of the Charter Documents of the Selling Stockholders, ExRes or any Significant Subsidiary; (b) require any consent, approval, authorization or permit of, filing with or notification to, any Governmental Authority, except (i) where the failure to
obtain such consent, approval, authorization or permit, or to make such filing or notification would not reasonably be expected to result in an ExRes Material Adverse Effect or (ii) those requirements that become applicable to ExRes or any

ERISA or its equivalent under foreign Law. 
  
 (k) Except as set
forth in Schedule 3.12(k), neither the execution and delivery of this Agreement nor the consummation of the transactions contemplated by this Agreement will (either alone or in conjunction with any other event) result in a material increase
in the amount of compensation or benefits or accelerate the vesting or timing of payment or cause the funding or delivery of any material compensation or benefits payable under any Employee Benefit Plan to or in respect of any person rendering
services to ExRes or its ERISA Affiliates, or require ExRes or its ERISA Affiliates to make a larger contribution to, or pay greater benefits under, any Employee Benefit Plan, or result in any material limitation on the right of ExRes or its ERISA
Affiliates to amend, merge, terminate or receive a reversion of assets from any Employee Benefit Plan or related trust. 
  
 (l) Each Employee Benefit Plan which is an “employee welfare benefit plan,” as such term is defined in Section 3(1) of ERISA, may be

all material respects with the health care continuation requirements of Part 6 of Title I of ERISA and Section 4980B of the Code. With respect to any Employee Benefit Plan that qualifies as a “health plan” or other “covered

 (m) Termination of employment of any Employee of ExRes or its

such payment for Taxes for any Straddle Tax Period shall be made by the Stockholders’ Representative to Buyer within five calendar days of the date when Buyer notifies the Stockholders’ Representative of an amount of such Taxes that is
payable to the relevant Taxing Authority. For purposes of this Section 5.8(a)(ii), in the case of any Taxes that are imposed on a periodic basis and are payable for a Straddle Tax Period, the portion of such Tax that relates to the portion of such
Tax period ending on the Closing Date shall: (A) in the case of any Tax other than Taxes based upon or related to income or receipts, be deemed to be the amount of such Tax for the entire Tax period multiplied by a fraction the numerator of which is
the number of days in the Tax period ending on the Closing Date and the denominator of which is the number of days in the entire Tax period; and (B) in the case of any Tax based upon or related to income or receipts be deemed equal to the amount
that would be payable if the relevant Tax period ended on the Closing Date. Any credits for Tax paid relating to a Straddle Tax Period shall be taken into account as though the relevant Tax period ended on the Closing Date. 
  
 (iii) Consistency in Preparation of Tax Returns. Except as consented
to in writing by the Stockholders’ Representative, which consent shall not be unreasonably withheld or delayed, or is required by Applicable Law, all such Tax Returns prepared in accordance with Sections 5.8(a)(i) and (ii) shall be prepared in
a manner consistent with the past practices of ExRes and its Subsidiaries, including any Tax elections and methods of Tax accounting. Furthermore, all Tax Returns (including Tax Returns for Post-Closing Tax Periods) shall report the transactions
that: (A) were the subject of the New England Purchase Agreement; and (B) gave rise to the Independence Restructuring Deduction, in a manner consistent with the past practices of ExRes and its Subsidiaries; provided, however, upon
receipt of a written notice from Buyer to Stockholders’ Representative of Buyer’s belief that a change in Applicable Law requires the transactions described in (A) and (B) above to be reported in a manner inconsistent with the past
practice of ExRes and its Subsidiaries, Stockholders’ Representative shall determine whether the change in reporting is required pursuant to Applicable Law. If Stockholders’ Representative agrees that such change in reporting is required
under Applicable Law, Buyer shall be permitted to report such transactions consistent with the notice provided to Stockholders’ Representative. The notice provided by Buyer shall provide details of how Buyer believes such transactions must now
be reported as required by Applicable Law. For purposes of this Section 5.8(a)(iii), a change in reporting that results in such transactions being reported in a manner not consistent with the past practices of ExRes and its Subsidiaries shall be
considered to be “required” only if the Stockholders’ Representative reasonably determines that the continued reporting of such transactions in a manner consistent with the past practices of ExRes and its Subsidiaries is not supported
by “Substantial Authority” as such term is defined in Section 6662 of the Code or any successor provisions that are similar thereto. 
  
 (b) Amendment of Tax Returns. Buyer shall not, and shall not permit any of its Affiliates to, amend any Tax Return of ExRes and its Subsidiaries
related to any Pre-Closing Tax Period or Straddle Tax Periods without the prior written consent of the Stockholders’ Representative, which consent shall not be unreasonably withheld or delayed. Similarly, the Stockholders’ Representative
shall not, and shall not permit any of its Affiliates to, amend any Tax Return of ExRes and its Subsidiaries related to any Pre-Closing Tax Period without the prior written consent of the Buyer, which consent shall not be unreasonably withheld or
delayed. 
  

 38 

 (c) Notice. The Stockholders’ Representative shall, and shall cause its Affiliates to, notify
Buyer in writing within 15 days after receipt of any notice (or otherwise becoming aware) by any of them of any Tax Proceeding with respect to ExRes and its Subsidiaries. Buyer shall, and shall cause ExRes and its Subsidiaries to notify the
Stockholders’ Representative in writing within 15 days after receipt of any notice (or otherwise becoming aware) by Buyer or any of its Affiliates of any Tax Proceeding with respect to ExRes and its Subsidiaries to the extent such notice
relates to any Pre-Closing Tax Period. The omission of any indemnified Party herein to give notice as provided in this Section 5.8(c) shall not relieve the indemnifying Party of its indemnification obligations under this Agreement except to the
extent that such omission results in failure of actual notice to the indemnifying Party and the indemnifying Party is materially damaged as a result of such failure to give notice. 
  
 (d) Tax Proceedings. 
  
 (i) The Selling Stockholders shall have the right to control and to represent ExRes and the Significant Subsidiaries and the Excluded Entities, through
counsel of their own choosing, and at their own expense, in any Tax Proceeding to the extent that any Buyer Indemnitee is, or may be, entitled to indemnification under Section 5.8(g) or to the extent the Selling Stockholders are entitled to any
refund under Section 5.8(f); provided, however, that: (A) Buyer shall have the right to participate through counsel of its own choosing and at its own expense in any such Tax Proceeding; (B) neither Buyer nor any of its Affiliates
shall be entitled in any way to compromise, release, waive, settle, modify or pay any claim with respect to Taxes for which any Buyer Indemnitee is or may be entitled to indemnification under Section 5.8(g) without prior written consent of the
Selling Stockholders, which consent shall not be unreasonably withheld or delayed; and (C) neither the Selling Stockholders nor any of their respective Affiliates shall be entitled in any way to compromise, release, waive, settle, modify or pay any
claim with respect to Taxes for which Buyer is, or may be, entitled to indemnification under Section 5.8(g) without the prior written consent of Buyer, which consent shall not be unreasonably withheld or delayed, but only to the extent that any such
compromise, release waiver, settlement, modification or payment may adversely impact Buyer, ExRes, the Significant Subsidiaries or the Excluded Entities (but, with respect to the Excluded Entities, only to the extent Buyer is obligated to share in
the Shared Indemnity Amount under Section 7.5(a)) for any Post-Closing Tax Period. Except to the extent provided in the preceding sentence, Buyer shall have the exclusive right to control, and to represent the interest of ExRes and the Significant
Subsidiaries for any Post-Closing Tax Period. 
  
 (ii)
Notwithstanding anything set forth in Section 5.8(d)(i) to the contrary, Buyer shall have the exclusive right to control and represent the interests of the Parties with respect to any Tax Proceeding for which Buyer is required to provide
indemnification under Section 7.1(b)(iii) so long as there are no other indemnification obligations by the Selling Stockholders pursuant to Section 5.8(g); provided, however, to the extent that any item for which Buyer has an
indemnification obligation as set forth herein is included in a consolidated Tax Return of which Exelon Corporation is the parent, Exelon Corporation shall have the right to control such Tax Proceeding and Buyer shall have the right to participate
(at its own expense) in such Tax Proceeding solely as such Tax Proceeding relates to such item for which Buyer has an indemnification obligation and Exelon Corporation shall not compromise, release, waive, settle, modify or pay any claim related to
such item without the consent of Buyer, which consent shall not be unreasonably withheld. 
  

 39 

 (iii) Notwithstanding anything set forth in Section 5.8(d)(i) or Section 5.8(d)(ii) to the contrary,
Buyer shall not provide (directly or indirectly, formally or informally, written or otherwise) any Taxing Authority with any materials, documentation or information related to the transactions that: (x) were the subject of the New England Purchase
Agreement; or (y) gave rise to the Independence Restructuring Deduction, in either case without the express written consent of the Stockholders’ Representative, which consent shall not be unreasonably withheld or delayed, unless required to do
so pursuant to an Order not requested by Buyer or its Affiliates. 
  
 (e) Cooperation; Record Retention. Each Party shall provide, and cause its Affiliates to provide, the other Parties with such assistance as may reasonably be requested in writing by them in connection with the preparation of any Tax
Return (including, at the request and sole expense of the Selling Stockholders, the filing of an amended Tax Return for a Pre-Closing Tax Period), the conduct of any Tax Proceeding and effectuating the terms of this Agreement, and each shall, and
shall cause its Affiliates, ExRes and its Subsidiaries to, retain and provide the requesting Party with any records or information which may be relevant to any such Tax Return, any such Tax Proceeding and Tax determination or other matter relating
to Taxes. Any information obtained pursuant to this Section 5.8(e) or pursuant to any other Section hereof providing for the sharing of information or review of any Tax Return shall be kept confidential by the Parties except to the extent a Party is
legally compelled to disclose such information. Each Party shall, and shall cause each of its Affiliates, ExRes and its Subsidiaries to, take any and all Commercially Reasonable Efforts, act in good faith, and cooperate fully, to permit the other
Parties to comply with their obligations hereunder. The Parties agree to retain, and to cause their Affiliates, ExRes and its Subsidiaries to retain, all books, records, Tax Returns, schedules, documents, work papers and other material items of
information relating to Taxes for any Pre-Closing Tax Period for the longer of: (i) the seven-year period beginning on the Closing Date; or (ii) the full period of the applicable statue of limitations, including any extension thereof. 
  
 (f) Refunds. To the extent any determination of Tax liability of
ExRes, the Significant Subsidiaries or the Excluded Entities, whether as the result of any audit or examination, a claim for refund, the filing of an amended Tax Return or otherwise, results in any refund of Taxes paid attributable to any
Pre-Closing Tax Period or Straddle Tax Period, any such refund shall belong to the Selling Stockholders, provided that in the case of any Tax refund with respect to any Straddle Tax Period, the portion of such Tax refund that shall belong to the
Selling Stockholders shall be that portion that is attributable to the portion of that period that ends on the Closing Date (determined on the basis of an interim closing of the books as of the Closing Date), and Buyer shall promptly pay any such
refund, and the interest actually received thereon, to the Stockholders’ Representative upon receipt thereof by Buyer or its Affiliates. Any and all other refunds shall belong to Buyer. 
  
 (g) Tax Indemnification. Except as provided herein, the Selling
Stockholders shall indemnify, defend and hold harmless each Buyer Indemnitee from and against any and all Tax Claims, or ExRes’, the Significant Subsidiaries’ and the Excluded Entities’ allocable portion 
  

 40 

 of such Tax Claims based on ExRes’, the Significant Subsidiaries’ and the Excluded Entities’ percentage
ownership of the Person subject to the Tax Claim, resulting from, arising out of or relating to: 
  
 (i) any and all Taxes imposed on or incurred by ExRes or its Significant Subsidiaries relating to (x): (A) any Pre-Closing Tax Period or portion of the
Straddle Tax Period that ends on the Closing Date and (B) any Pre-Closing Tax Period or portion of the Straddle Tax Period that ends on the Closing Date for Taxes incurred by ExRes, the Significant Subsidiaries or the Excluded Entities for the
transactions that were the subject of the New England Purchase Agreement, (y) the unpaid Taxes of any Person (other than ExRes, the Significant Subsidiaries and the Excluded Entities) including under Treasury Regulation Section 1.1502-6 (or any
similar provision of state, local or foreign Law) as a transferee, successor, or by Contract relating to the Pre-Closing Tax Period or portion of the Straddle Tax Period that ends on the Closing Date or (z) the unpaid Taxes of Exelon Corporation
arising solely as a result of ExRes or its Subsidiaries having been included in Exelon Corporation’s federal consolidated income Tax Return or similar state, local or foreign Tax Return, prior to the Closing Date; 
  
 (ii) any and all Taxes imposed on or incurred by the Excluded Entities
relating to (x) any Pre-Closing Tax Period or portion of the Straddle Tax Period that ends on the Closing Date but excluding any Taxes incurred by ExRes, the Significant Subsidiaries or the Excluded Entities for the transactions that were the
subject of the New England Purchase Agreement or (y) the unpaid Taxes of any Person (other than ExRes the Significant Subsidiaries and the Excluded Entities) including under Treasury Regulation Section 1.1502-6 (or any similar provision of state,
local or foreign Law) as a transferee, successor, or by Contract relating to the Pre-Closing Tax Period or portion of the Straddle Tax Period that ends on the Closing Date. For the avoidance of doubt, any indemnification for Taxes resulting from,
arising out of or related to the Independence Restructuring Deduction or the transactions that were the subject of the New England Purchase Agreement shall be indemnified pursuant to Section 5.8(g)(i) and not this Section 5.8(g)(ii); 
  
 (iii) any and all Taxes imposed on or incurred by the Excluded Entities
relating to (x) any Post-Closing Tax Period or (y) any unpaid Taxes of any Person (other than ExRes, the Significant Subsidiaries and the Excluded Entities) including under Treasury Regulation Section 1.1502-6 (or any similar provision of state,
local or foreign Law) as a transferee, successor, or by Contract relating to any Post-Closing Period; provided, however, the Buyer Indemnitees shall not be indemnified under this Section 5.8(g)(iii) for any and all Taxes imposed on or
incurred by the Excluded Entities for matters provided in Section 5.15 through 5.24, 5.27, 5.29 and 5.30, including the receipt or payment of funds by ExRes, the Significant Subsidiaries or the Excluded Entities pursuant to such Sections;

  
 (iv) the breach of any representation or warranty of the
Selling Stockholders provided in Section 3.9; or 
  
 (v) any
increase in Taxes or decrease in Tax attributes imposed on Buyer, ExRes or the Significant Subsidiaries that arise solely as a result of the Stockholders’ Representative determining that Buyer is prevented from reporting the transactions that
(xx) were the subject of the New England Purchase Agreement or (yy) gave rise to the Independence Restructuring Deduction, in either case, in a manner inconsistent with the past practices of ExRes or its Subsidiaries provided for in the second
sentence of Section 5.8(a)(iii); 
  

 41 

 provided, however, that the Selling Stockholders shall not indemnify any Buyer Indemnitee for: (A) any
Taxes imposed on or incurred by ExRes, the Significant Subsidiaries or the Excluded Entities as a result of a modification or deemed modification of any Swap Agreement or related agreements that would not have been incurred but for the actions of
Buyer or its Affiliates, (B) any Taxes imposed on or incurred by ExRes, the Significant Subsidiaries or the Excluded Entities as a result of any cancellation of indebtedness (“COD”) income that would not have been incurred but for
the actions of Buyer or its Affiliates and (C) any Taxes for Pre-Closing Tax Periods incurred by ExRes, the Significant Subsidiaries or the Excluded Entities as a result of any actions taken by Buyer or its Affiliates in violation of its obligations
pursuant to Section 5.8(d). 
  
 (h) Buyer Payments for the
Independence Restructuring Deduction. If the Selling Stockholders make an indemnification payment to Buyer pursuant to this Agreement related to or arising from the Independence Restructuring Deduction, Buyer shall make a payment to the Selling
Stockholders in the following circumstances: 
  
 (i) If Buyer
sells any of: (A) Independence; (B) the assets of Independence; or (C) any direct or indirect interest in Independence that is owned by Buyer or any of its Affiliates (“Independence Interests”), Buyer shall pay the Selling
Stockholders on the date of such sale an amount equal to (x) the effective tax rate on such date multiplied by (y) the increase, if any, in the usable tax basis, if any, created by a recharacterization of the Independence Restructuring Deduction or,
alternatively, an amount equal to any refund received by Buyer or an amount as determined in Section 5.8(i)(i) for any increase in Buyer’s Net Operating Losses (“NOL”) as a result of any increase in tax basis created by such
recharacterization; 
  
 (ii) If Buyer purchases the Reservoir
Loan, Buyer shall pay the Selling Stockholders on the date of such acquisition an amount equal to (x) the effective tax rate multiplied by (y) any deduction recognized and COD income foregone as a result of a recharacterization of the Independence
Restructuring Deduction or, alternatively, an amount equal to any refund received by Buyer or an amount as determined in Section 5.8(i)(i) for any increase in Buyer’s NOL as a result of any deduction created and COD income foregone as a result
of such recharacterization; and 
  
 (iii) If Buyer does not sell
the Independence Interests or purchase the Reservoir Loan, Buyer shall pay the Selling Stockholders an amount equal to any actual tax savings realized in years 2015-2034 as a result of a reduction of income in those years as a result of a
recharacterization of the Independence Restructuring Deduction. 
  
 If the Selling
Stockholders’ aggregate payments to Buyer for indemnification claims exceed the limit set forth in Section 7.5(a), for purposes of calculating Buyer’s obligation to make a payment to the Selling Stockholders pursuant to this Section
5.8(h), the following shall apply: (1) any payments for Tax Claims made by the Selling Stockholders to Buyer with respect to the Independence Restructuring Deduction pursuant to Section 5.8(g) shall be deemed to be paid 
  

 42 

 first; and (2) any payments to be made by Buyer to the Selling Stockholders pursuant to this Section 5.8(h) shall be
limited to the actual amount of the indemnity payments made by the Selling Stockholders to Buyer attributed to the Independence Restructuring Deduction by virtue of item (1) above. To the extent any indemnification claims pursuant to Sections
7.1(a)(i) and (iii) exceed the limitation amount set forth in Section 7.5(a) (the “Excess Cap Amount”) and Buyer is otherwise obligated to make a payment to Selling Stockholders under this Section 5.8(h), Buyer shall not be
obligated to make a payment pursuant to this Section 5.8(h) to the extent such payment obligation is less than the Excess Cap Amount and to the extent such payment obligation pursuant to this Section 5.8(h) exceeds the Excess Cap Amount, Buyer shall
pay such excess amount to the Selling Stockholder (the “Excess Cap Payment”). For the avoidance of doubt, the provisions of this Section 5.8(h) only govern what has been deemed paid by the Parties in respect of the limitations of
Section 7.5(a) and do not increase, decrease or otherwise alter the limitations provided for in Section 7.5(a) and the intent and operation of these provisions is illustrated on Schedule 5.8(h). 
  
 (i) Net Operating Loss Utilization. 
  
 (i) If a Tax adjustment by a Taxing Authority is made for any Pre-Closing
Tax Period or the portion of the Straddle Tax Period ending on or before the Closing Date and such adjustment would trigger a Tax indemnity pursuant to Section 5.8(g), to the extent the liability is for income Taxes, ExRes, the Significant
Subsidiaries or the Excluded Entities shall carry back their NOLs, to the extent permitted by Law, to offset such income tax liability and the Selling Stockholders shall compensate Buyer for such NOL utilization as follows: (A) to the extent Buyer
acquires the Reservoir Loan and recognizes COD income, the Selling Stockholders shall compensate Buyer for the use of such NOLs by cash payment in an amount equal to the effective Tax rate multiplied by the amount of such NOLs or (B) to the extent
Buyer does not acquire the Reservoir Loan or acquires the Reservoir Loan but does not recognize COD income, the Selling Stockholders shall compensate Buyer for the use of such NOLs by cash payment in the amount equal to the present value of the
available NOLs for each Tax year using a 10% discount rate per annum, the computation of which is set forth on Schedule 5.8(i) (which shall use as the starting point for such calculation the NOLs reported on the Tax Return of ExRes and its
Subsidiaries for the Tax Period ending on the Closing Date). 
  
 (ii) If the amount of the NOLs utilized in consummating the Preliminary Transactions, after taking into account any NOLs generated as a result of the Preliminary Transactions, is in excess of the amount set forth on Schedule 5.8(i)
(the “Excess NOL Amount”) the Selling Stockholders shall compensate Buyer for the use of such Excess NOL Amount in the manner set forth in Section 5.8(i)(i). 
  
 (j) Transfer Taxes. Payment for all stamp, documentary, recording and similar transfer Taxes (the “Transfer
Taxes”) incurred in connection with this Agreement (other than Transfer Taxes that result from the Preliminary Transactions, which shall be paid by the Selling Stockholders) and the transactions contemplated hereby shall be shared equally
between Buyer on the one hand and the Selling Stockholders on the other. Buyer shall file, to the extent required by applicable law, all necessary Tax Returns and other documentation with respect to all such transfer Taxes, and, if required by
Applicable Law, ExRes and its Subsidiaries shall join in the execution of any such Tax Returns or other documentation. Buyer shall provide 
  

 43 

 substantially final drafts of such Tax Returns to the Stockholders’ Representative no later than 15 calendar days
prior to the due date for such Tax Return and shall incorporate any reasonable comments relating to such Tax Returns timely provided in writing by the Stockholders’ Representative. Audits of any such Tax Returns shall be controlled jointly by
Buyer and the Selling Stockholders. Refunds of any Transfer Taxes (together with any associated interest) shall be shared equally by Buyer, on the one hand, and Selling Stockholders on the other hand. Notwithstanding the foregoing, the foregoing
shall not be interpreted to require Buyer to pay any of the Selling Stockholders’ income, gain or similar Taxes arising from any gain, income or other recognition resulting from the sale and purchase transactions contemplated by this Agreement,
and if Buyer is required under applicable domestic or foreign law to withhold and remit Taxes from the Purchase Price that are in respect of the foregoing and that are not otherwise Transfer Taxes, Buyer shall give reasonable notice of such fact to
the Stockholders’ Representative and the cash payable to the Selling Stockholders at Closing shall be reduced by the amount of such withholdings. 
  
 (k) Tax Treatment of Allegheny Companies and MRA Companies. The Parties shall treat the Tax ownership of the Allegheny Companies and the MRA
Companies consistent with the legal ownership of such entities and shall file all applicable Tax Returns in a manner consistent with such legal ownership. In addition, the Parties shall cooperate in drafting any Decommissioning or related agreements
consistent with the preceding sentence. 
  
 (l) No
§338(h)(10) Election. Each Party covenants and agrees that no election under §338(h)(10) or §338(g) of the Internal Revenue Code will be made with regard to the purchase of the ExRes Shares under this Agreement. 
  
 (m) Tax Sharing Agreements. Except for the agreements listed on
Schedule 5.8(m), all Tax sharing agreements or similar agreements between ExRes and its Stockholders, shall be terminated as of the Closing Date and, after the Closing Date, ExRes shall not be bound thereby or have any liability or obligation
with respect to such agreements. 
  
 (n) Conflict. In the
case of any conflict between any of the terms set forth in this Section 5.8 and the terms set forth in Article VII, the terms of this Section 5.8 shall control. 
  

(o) Swap Credit Return Transaction. The Parties agree that the transactions that occur as part of the Swap Credit Return Transaction shall be
treated for Tax purposes as occurring at the beginning of the day following the Closing Date, including, if applicable, pursuant to Treasury Regulation 1.1502-76(b)(1)(ii)(B). 
  
 5.9 Indemnification and Insurance. 
  
 (a) Buyer agrees that all rights to indemnification and exculpation existing in favor of ExRes and its Subsidiaries or any
present or former director, officer, employee, fiduciary or agent of ExRes and its Subsidiaries, including the advancing of related expenses in each case as provided in the respective Charter Documents of ExRes and its Subsidiaries in effect as of
the date hereof, with respect to matters occurring prior to the Closing, shall survive the Closing and shall continue in full force and effect until November 25, 2009. Buyer shall not amend or restate or permit any of its Subsidiaries to amend or
restate any such Charter Document 
  

 44 

 in any manner that would adversely affect the indemnification or exculpation rights of any such present or former
director, officer, employee, fiduciary or agent provided by the foregoing. To the extent that any Person who was a director, officer, employee, fiduciary or agent of ExRes or any of its Subsidiaries prior to Closing is paid by Buyer pursuant to
indemnification or exculpation pursuant to the Charter Documents of ExRes or any of its Subsidiaries, which indemnification or exculpation is not paid by the insurance described in this Section 5.9, Exelon shall reimburse the Buyer for such unpaid
amount. 
  
 (b) Exelon shall provide directors’ and
officers’ “liability run-off” insurance with respect to ExRes and its Subsidiaries until November 25, 2009, which insurance shall cover wrongful acts occurring between December 18, 2000 and the Closing Date. Such coverage shall be no
less favorable in coverage and amount than the directors’ and officers’ insurance for ExRes and its Subsidiaries in effect immediately prior to the Closing Date. Exelon shall acquire and pay for in full prior to the Closing Date such
directors’ and officers’ “liability run-off” insurance. 
  
 (c) Following the Closing, for as long as Exelon is responsible under Section 5.15 for the payment to Sithe of costs and expenditures associated with any Allegheny Company, Buyer shall cause Sithe to continue to
maintain, at Exelon’s expense to the extent not paid by the Allegheny Companies in the Ordinary Course, with respect to such Allegheny Company, insurance (other than directors’ and officers’ insurance, which is addressed in Sections
5.9(a) and (b)) that is no less favorable in coverage and amount than the applicable insurance in effect for such Allegheny Company immediately prior to the Closing. Exelon shall be responsible for any and all costs, liabilities and obligations
related to such insurance policies and claims or losses, including deductibles, self-insured retentions, claims adjusting expenses, loss conversion factor expenses, retroactive premium adjustments, audits, collateral requirements and associated
benefits and any other costs that become due and payable in connection with such insurance coverages and/or associated claims or losses, to the extent not paid by the Allegheny Companies in the Ordinary Course. 
  
 (d) Following the delivery, in accordance with Section 5.16, of a
Decommissioning Notice with respect to any MRA Company that is not an Ogdensburg Company, for as long as Exelon is responsible under Section 5.16 for the payment to Buyer of costs and expenditures associated with the Decommissioning of such MRA
Company, Buyer shall cause Sithe to maintain, at Exelon’s expense to the extent not paid by the MRA Companies in the Ordinary Course, with respect to each such MRA Company, insurance (other than directors’ and officers’ insurance,
which is addressed in Sections 5.9(a) and (b)) that is no less favorable in coverage and amount than the applicable insurance in effect for such MRA Company immediately prior to the Closing. Exelon shall be responsible for any and all costs,
liabilities and obligations related to such insurance policies and claims or losses, including deductibles, self-insured retentions, claims adjusting expenses, loss conversion factor expenses, retroactive premium adjustments, audits, collateral
requirements and associated benefits and any other costs that become due and payable in connection with such insurance coverages and/or associated claims or losses, to the extent not paid by the MRA Companies in the Ordinary Course. 
  

 45 

 (e) Following the Closing, for as long as Exelon is responsible under Section 5.16 for the payment to
Buyer of costs and expenditures associated with any Ogdensburg Company, Buyer shall cause Sithe to maintain, at Exelon’s expense to the extent not paid by the Ogdensburg Companies in the Ordinary Course, with respect to such Ogdensburg Company,
insurance (other than directors’ and officers’ insurance, which is addressed in Sections 5.9(a) and (b)) that is no less favorable in coverage and amount than the applicable insurance in effect for such Ogdensburg Company immediately prior
to the Closing. Exelon shall be responsible for any and all costs, liabilities and obligations related to such insurance policies and claims or losses, including deductibles, self-insured retentions, claims adjusting expenses, loss conversion factor
expenses, retroactive premium adjustments, audits, collateral requirements and associated benefits and any other costs that become due and payable in connection with such insurance coverages and/or associated claims or losses, to the extent not paid
by the Ogdensburg Companies in the Ordinary Course. 
  
 (f) The
Selling Stockholders will, and will cause ExRes to use Commercially Reasonable Efforts to, renew any existing insurance coverage listed on Schedule 3.14, and the Selling Stockholders will not, and will not permit ExRes or any of its
Subsidiaries to, renew any such existing insurance coverage for a term that extends beyond the Closing Date without Buyer’s prior written consent, which consent shall not be unreasonably withheld or delayed; provided, however, in
the event that Buyer’s approval cannot be obtained, the Selling Stockholder shall be permitted to renew such coverage with terms no less favorable in all material respects than those currently in effect or, if such terms are not available, on
commercially reasonable terms. The Selling Stockholders shall use Commercially Reasonable Efforts to obtain such renewals without provisions providing for the implementation of penalties relating to the cancellation of any such policy. 

 
 5.10 Credit Support. 
  
 (a) Buyer shall use Commercially Reasonable Efforts to cause the Selling
Stockholders and their Affiliates to be released at or immediately after the Closing from all guarantees, letters of credit or other credit support listed in Schedule 5.10(a). 
  
 (b) Except as set forth in (c) and (d) below, at Closing, Buyer will provide the necessary credit support for ExRes and the
Significant Subsidiaries to carry on its or their respective business activities. 
  
 (c) Selling Stockholders will provide and shall maintain the guarantees, letters of credit and any other types of credit support, including restricted cash collateral referred to in Section 5.24, necessary for the MRA
Companies, the Allegheny Companies and the Excluded Entities, except that, with respect to the MRA Companies, Selling Stockholders shall be released from any obligation to provide credit support for any MRA Company if Buyer fails to provide a
Decommissioning Notice with respect to an MRA Company within the time period set for in Section 5.16(a). Schedule 5.10(c) contains a list of all guarantees, letters of credit and other credit support provided by Exelon and its Affiliates with
respect to the MRA Companies and the Excluded Entities. If a Decommissioning Notice is not delivered by Buyer within the time period set forth in Section 5.16(a) with respect to an MRA Company, Buyer shall cause the Selling Stockholders and their
Affiliates to be released within 210 days after the Closing from all 
  

 46 

 guarantees, letters of credit or other credit support listed in Schedule 5.10(c) with respect to such MRA Company.
If an event occurs (or fails to occur) between the Closing Date and the effective date of a Decommissioning Notice with respect to any MRA Company for which Exelon or its Affiliates are required to make a payment pursuant to any such guarantee,
letter of credit or other credit support, Buyer shall promptly pay to Exelon an amount equal to any such payment made by Exelon or its Affiliates. 
  
 (d) The Parties further agree to take the actions specified in Schedule 5.10(d) (the “Swap Credit Return Transaction”).

  
 5.11 Employee Matters. 
  
 (a) As of the Closing Date, neither ExRes nor any of its Subsidiaries shall
have any employees, except: (i) the employees of Sithe identified on Schedule 5.11(a) and the TEG/TEP Employees; and (ii) the employees of SEPS identified on Schedule 5.11(b). The employment of the individuals listed on such Schedules
above who are Active Employees as of the Closing Date shall continue immediately after the Closing, and each such individual is referred to in this Agreement as a “Continuing Employee.” All full-time and part-time employees,
employees on workers’ compensation, military leave, maternity leave, leave under the Family and Medical Leave Act of 1993, or sick leave, and employees on other approved leaves of absence with a legal or contractual right to reinstatement
listed on such Schedules are referred to in this Agreement as “Active Employees.” 
  
 (b) With respect to any new or replacement employee benefit plans sponsored by Buyer or its Subsidiaries following the Closing Date, Buyer shall, and
shall cause its Subsidiaries to, (i) waive all pre-existing conditions, exclusions, and waiting periods with respect to participation and coverage requirements applicable to the Continuing Employees and their covered dependents under any new or
replacement health insurance plan in which the Continuing Employees may be eligible to participate after the Closing Date, (ii) provide each Continuing Employee with credit for payments made by such employee or their covered dependents prior to the
Closing Date for purposes of satisfying any applicable co-payment, deductible or out-of-pocket requirements under any new or replacement health insurance plan in which such employees or their covered dependents may be eligible to participate after
the Closing Date, and (iii) give credit to the Continuing Employees, solely for purposes of satisfying any vesting or eligibility requirements of any new or replacement employee benefit plan, program or arrangement in which Continuing Employees may
be eligible to participate after the Closing Date, for services rendered prior to the Closing Date to ExRes, or any of its Subsidiaries, or, to the extent recognized by the ExRes benefit plans in existence as of the date of this Agreement, for
services rendered to any other Person; provided, that any of the foregoing shall not apply to the extent that it would result in duplication of benefits. 
  
 (c) (i) The Selling Stockholders shall cause Sithe to take all actions necessary to terminate the Sithe Energies Group Retirement 401(k) Plan (the
“Sithe 401(k) Plan”) and the Sithe Energies, Inc. Excess Benefit Plan immediately prior to the Closing Date on terms approved in writing by Buyer, which approval shall not be unreasonably withheld or delayed. 
  

 47 

 (ii) In connection with the termination of the Sithe 401(k) Plan, Buyer agrees that the Sithe 401(k)
Plan will be amended in the following two respects. First, the amendment will provide that after the Sithe 401(k) Plan’s termination, participants, who are employed by a participating employer, with current outstanding loans may continue to
repay such loans until Sithe 401(k) Plan distributions commence. Second, the amendment will provide that (A) if the Sithe 401(k) Plan terminates before December 31, 2004, then the 2004 profit sharing contribution will be allocated as of the
termination date instead of December 31, 2004 and (B) if the Sithe 401(k) Plan terminates after 2004, for purposes of allocating the profit sharing contribution, if any, the termination date of the Sithe 401(k) Plan shall be substituted for the last
day of the plan year. The terms of this amendment shall be approved in advance of execution by Buyer, which approval shall not be unreasonably withheld or delayed. 
  
 (iii) After the Sithe 401(k) Plan receives a favorable IRS determination letter stating that it is qualified as of its date
of termination, Buyer agrees to direct the appropriate defined contribution plan or plans that it or its Subsidiaries maintain to accept direct rollovers of individuals’ account balances, including outstanding plan loans and promissory notes,
from the Sithe 401(k) Plan. 
  
 (d) In addition, the Parties shall
cooperate in taking Commercially Reasonable Efforts to cause those Continuing Employees designated by the Buyer to terminate participation on or after the Closing in those Employee Benefit Plans designated by the Buyer and to commence participation
on or after the Closing in employee benefit plans maintained by the Buyer or its Subsidiaries. 
  
 (e) With respect to any individual who is a Sithe Employee, or who is designated as an Independence employee on Schedule 5.11(b), the Selling Stockholders shall reimburse ExRes or any of its Significant Subsidiaries,
on a monthly basis for all Damages incurred on or after the Closing Date that are attributable to any period of time prior to and including the Closing Date, including any salary, employment contract, nonqualified plan, bonus, severance payments,
termination and other employment-related costs relating to calendar year 2004 and prior calendar years; provided, however, the Selling Stockholders shall not have a reimbursement obligation with respect to any such payments that are used to increase
the unrestricted cash amount described in Section 6.1(e). For purposes of the Selling Stockholders’ reimbursement obligations not subject to the last sentence of this Section 5.11(e), each MRA Employee shall be treated as a Sithe Employee until
a Decommissioning Notice is effective as provided in Section 5.16. After such effectiveness, an MRA Employee shall be treated as an Allegheny Employee for reimbursement purposes, but only to the extent of any such amounts not reimbursed by such
Allegheny Company or MRA Company. 
  
 (f) With respect to any
individual who is an Allegheny Employee or who is or was employed by ExRes or one of its prior or current Affiliates or Subsidiaries but who is not a Sithe Employee or an employee identified on Schedule 5.11(b) as an Independence employee,
the Selling Stockholders shall reimburse ExRes or any Significant Subsidiary on a monthly basis for all Damages incurred on or after the Closing Date, including any employment contract, COBRA, non-qualified plan, bonus, severance, termination and
Employee Benefit Plan payments and other employment-related costs; provided, however, the Selling Stockholders shall not have a reimbursement obligation with respect to any such payments that are used to increase the unrestricted cash amount
described in Section 6.1(e) or to the extent any such amounts are reimbursed by an Allegheny Company or MRA Company, as applicable. 
  

 48 

 (g) The Selling Stockholders shall reimburse ExRes or any Significant Subsidiary for all Damages incurred
on or after the Closing Date that are related or attributable to the employee benefit plans, programs and policies sponsored or maintained by prior Affiliates or Subsidiaries of ExRes that are not Affiliates or Subsidiaries of ExRes as of the
Closing Date or such entities’ participation in and withdrawal from the Employee Benefit Plans. 
  
 (h) Additional Selling Stockholder Reimbursements. 
  
 (i) Welfare Plan Benefits. Notwithstanding any other provision of this Agreement to the contrary, Selling Stockholders shall reimburse ExRes or
any Significant Subsidiary, on a monthly basis, for all Damages incurred on or after the Closing Date for Self-Funded Welfare Plan Reimbursements for (A) benefits provided in accordance with COBRA, to the extent not reimbursed by an Allegheny
Company or an MRA Company, as applicable, to MRA Employees, Allegheny Employees, and individuals who terminated employment with ExRes or one of its Subsidiaries on or prior to the Closing Date (“Former Employees”) and (B) benefits
provided in accordance with the Sithe Energies, Inc. Severance Benefit Plan for Designated Employees (“Severance Plan”) to Sithe Employees and Former Employees. In addition, the Selling Stockholders shall reimburse ExRes or any
Significant Subsidiary, on a monthly basis, for any other Damages incurred that are related or attributable to the provision of health care benefits under the Severance Plan. For purposes of this Section 5.11(h), “Self-Funded Welfare Plan
Reimbursement” shall mean the dollar amount of benefits, including medical, dental and vision care benefits, paid by a Self-Funded Welfare Plan with respect to a participant less the dollar amount of any contributions made by such participant
during the particular measuring period being used for reimbursement purposes. For purposes of this Section 5.11(h), “Self-Funded Welfare Plan” shall mean an employee welfare benefit plan, as defined in Section 3(1) of ERISA, of ExRes or
one of its ERISA Affiliates, the benefits of which are not provided through insurance contracts or policies issued by an insurance company, other than stop loss policies.

to Closing, but paid after the Closing; and (B) with respect to MRA Employees and Allegheny Employees, prior to such employee’s termination but paid after such termination, provided that such benefit payment is not reimbursed by an Allegheny
Company or an MRA Company. 
  
 (iii) Accrued Vacation.

 49 

 an MRA Company, as applicable; provided, however, that Buyer and its Significant Subsidiaries shall not
take any action that will result in the acceleration of the payment of such accrued vacation amounts other than as a result of employee termination or provide for the non-cash payment of such accrued vacation amounts.

5.11(b) as Sithe Employees may be eligible to participate in after the Closing Date. Buyer shall have no obligation to provide to any TEG/TEP Employee any additional severance, bonus, retention, incentive, or other payments and benefits unless
requested and paid for by Exelon. The Parties acknowledge that Sithe retains the right to terminate the employment of any TEG/TEP Employee for Cause after providing Exelon with three days’ prior written notice of such termination, without any
liability and obligation to Sithe or Buyer, and that neither Buyer nor Sithe has any obligation to replace any TEG/TEP Employee that resigns or whose employment is terminated for Cause. 
  
 5.13 WARN Act. If a plant closing or a mass layoff occurs or is deemed to occur after Closing with respect to ExRes
or any of its Subsidiaries or any of their respective facilities in connection with the transactions contemplated by this Agreement, after Closing, Buyer shall be solely responsible for providing all notices required under the WARN Act (and any
similar applicable state or local Laws) and for taking all remedial measures including the payment of all liabilities and obligations if such notices are not provided.

Cause. 
  
 5.15 Allegheny Companies. Following the Closing:

  
 (a) Subject to Section 5.15(c), Buyer shall cause ExRes and
its Subsidiaries to operate the business and affairs of the Allegheny Companies in the Ordinary Course. Except as required by Applicable Law or a Contract in existence as of the Closing Date, Buyer shall not and shall not permit ExRes or any of its

 (b) Buyer shall make corporate personnel of ExRes and its Subsidiaries, which shall include one or more of the Designated Employees designated by Exelon, reasonably available at no cost to Exelon, other than its reimbursement of
out-of-pocket costs incurred in connection therewith, to assist Exelon with any action relating to the Allegheny Companies. From the Closing until December 31, 2005, Buyer shall not and shall not permit ExRes or its Subsidiaries to terminate any

thereof to such Allegheny Company and any Subsidiary of ExRes and (ii) Buyer and its Affiliates shall be entitled to state publicly that such determination was made by Exelon and that neither Buyer nor its Affiliates shall incur any liability or
obligation with respect thereto (provided, that Buyer will give Exelon reasonable notice before its first such public statement and shall give Exelon a reasonable opportunity to comment on such public statement). 
  
 (d) Exelon, in its sole discretion and expense, shall have the option to
cause ExRes and its Subsidiaries, through Buyer, to terminate, transfer or take any other reasonable 
  

 51 

 action with respect to the Allegheny Operating and Management Agreements. If Exelon deems it desirable to take such
action with respect to the Allegheny Operating and Management Agreements, it shall communicate such decision to Buyer in writing, upon the receipt by Buyer of which Buyer shall use Commercially Reasonable Efforts to effectuate such termination in a
prompt and timely manner and in accordance with Exelon’s instructions. 
  
 (e) Within ten Business Days following the end of each successive month after the Closing, Buyer shall cause ExRes and its Subsidiaries to provide to Exelon a statement setting forth, in reasonable detail, any costs

following the Closing Date (“Excluded Taxes”)) that have not been reimbursed under the Allegheny Operating and Management Agreements or are not reasonably expected to be reimbursed promptly after such costs or expenditures were
incurred or paid by ExRes and its Subsidiaries in the month immediately preceding such statement with respect to the Allegheny Companies. Within ten Business Days after receiving such statement, Exelon shall pay to ExRes and its Subsidiaries an
amount, in cash, equal to the total of all costs and expenditures (other than Excluded Taxes) set forth on such statement. Notwithstanding the foregoing, Exelon shall not be required to reimburse ExRes and its Subsidiaries for any costs or

Exelon shall have given its prior written consent to such costs or expenditures (other than Taxes), which consent shall not be unreasonably withheld or delayed. 
  

(f) If Buyer reasonably believes, based on estimates, invoices or documentation provided to Exelon by Buyer, that ExRes and its Subsidiaries will be
entitled to payment under Section 5.15(e) in any month in excess of $250,000, Buyer may provide a preliminary statement to Exelon during the preceding month stating such fact and Exelon shall advance to ExRes and its Subsidiaries the amount set
forth in such preliminary statement within ten Business Days after receiving such preliminary statement. If the estimated payment set forth for a month in a preliminary statement varies from the actual payment made for such month, the statement for
such month shall take such variance into account and the Parties will make true-up payments accordingly.

completion of Decommissioning activity with respect to such MRA Company, to be netted against any negative MRA Value in such successive month(s). 
  
 If Buyer reasonably believes, based on estimates, invoices or documentation provided to Exelon by Buyer, that the MRA Value (after giving effect to any netting pursuant
to this Section 5.16(c)) for any month will be negative and in excess of $250,000, Buyer may provide a preliminary statement to Exelon during the preceding month stating such fact and Exelon shall advance to Buyer the amount set forth in such
preliminary statement within ten Business Days after receiving such preliminary statement. If the estimated MRA Value set forth for a month in a preliminary statement varies from the actual MRA Value for such month, the Monthly MRA Statement for

dispute is resolved. If any Party fails to make timely payments of any such invoiced amount, then the Party to whom the amount is owed shall be entitled to collect from the owing Party the amount of such invoice together with interest at the
“prime rate” as published in The Wall Street Journal on any unpaid amount that is determined to be due.

 (a) General. In case at any time after the Closing any further action
is necessary or desirable to carry out the purposes of this Agreement, each Party will take such further action (including executing and delivering such further instruments and documents) as any other Party reasonably may request, all at the
requesting Party’s sole cost and expense (unless the requesting Party is entitled to indemnification therefor under this Agreement). In addition, at the Selling Stockholders’ request, Buyer shall provide information to, and cooperate with,
the Selling Stockholders with respect to the ownership and operation of the MRA Companies and the Allegheny Companies to enable the Selling Stockholders to fulfill their obligations under this Agreement related to the MRA Companies (if a

the Excluded Entities. 
  
 (b) Litigation Support. So long
as any Party (the “Requesting Party”) is a party to, or actively is contesting or defending against any Action in connection with (i) the transactions contemplated by this Agreement or (ii) any fact, situation, circumstance, status,
condition, activity, practice, plan, occurrence, event, incident, action, failure to act, or transaction on or prior to the Closing Date involving ExRes, any Significant Subsidiary or any Excluded Entity, each other Party will cooperate with such
Party and such Party’s counsel in the contest or defense, make available their personnel, and provide such testimony and access to their books and records as will be necessary in connection with the contest or defense, at the sole cost and
expense of the Requesting Party (unless the Requesting Party or one of its Affiliates is entitled to indemnification therefor under this Agreement). 
  
 (c) Confidentiality. Each Selling Stockholder will treat and hold as such all of the Confidential Information, refrain from using any of the
Confidential Information except in connection with this Agreement, and, upon the request of Buyer, deliver promptly to Buyer or destroy all tangible embodiments (and all copies) of the Confidential Information which are in such Selling
Stockholder’s possession in each case, forever, provided, however, that Selling Stockholder shall be entitled to retain one copy of such Confidential Information. If any Selling Stockholder is ever requested or required (by oral question or
request for information or documents in any Action) to disclose any Confidential Information, that Selling Stockholder will 
  

 59 

 notify Buyer promptly of the request or requirement so that Buyer may seek an appropriate protective Order or waive
compliance with this Section. If, in the absence of a protective Order or the receipt of a waiver hereunder, any Selling Stockholder that, on the written advice of counsel, is compelled to disclose any Confidential Information to any Governmental
Authority or else stand liable for contempt, that Selling Stockholder may disclose the Confidential Information to the Governmental Authority; provided, however; that the disclosing Selling Stockholders will use their Commercially Reasonable Efforts
to obtain, upon the reasonable request of Buyer, an Order or other assurance that confidential treatment will be accorded to such portion of the Confidential Information required to be disclosed as Buyer may designate. “Confidential
Information” shall have the same meaning as “Evaluation Material” as defined in the Confidentiality Agreement without regard to clause (ii) of the second paragraph of the Confidentiality Agreement, other than with respect to any
material or information of the Excluded Entities. 
  
 (d)

Stockholders or its Affiliates, any employee or then currently active independent contractor of SEPS providing services to any Independence Entity or any person who was an employee or then currently active independent contractor of SEPS providing
services to any Independence Entity, within the six-month period immediately preceding such solicitation of employment, other than such person (A) whose employment or independent contractor relationship was terminated by the applicable Person, or
(B) who independently responded to a general solicitation for employment by such Selling Stockholder or such Selling Stockholder’s Affiliate; or (ii) induce or attempt to induce, any employee or independent contractor of SEPS providing services
to any Independence Entity, to terminate such employee’s employment or independent contractor’s active contractual relationship with such Person.

 60 

 subject to Selling Stockholders’ approval, such approval not to be unreasonably withheld or delayed (the
“Waiver Procedure”); (b) after Buyer delivers such notice, the Selling Stockholders and ExRes shall cause Independence and SIFC to promptly commence obtaining, and use Commercially Reasonable Efforts to obtain, such Waiver
substantially in accordance with such Waiver Procedure; and (c) Buyer shall promptly reimburse Independence and SIFC for all out of pocket costs and expenses (including any payments to the Trustee or Holders of Outstanding Bonds (as such terms are
defined in the Trust Indenture) including their respective counsel, if required) it reasonably incurs in obtaining such Waiver (provided, that prior to incurring or committing to any significant cost or expense for which it may claim reimbursement,

statute, shall not reduce the amount of Damages for which such Buyer Indemnitee is due indemnification. 
  
 7.2 Procedure; Notice. 
  
 (a) The expiration or termination of the availability of indemnification under this Article VII with respect to any representation or warranty shall not
affect the Parties’ obligations under this Article VII if the Person required to provide indemnification under this Agreement (the “Indemnifying Party”) has received proper notice of the claim or event for which indemnification
is sought prior to such expiration or termination. 
  
 (b) Except
to the extent otherwise provided in Section 10.6, the rights and remedies of the Indemnitees under this Article VII are exclusive and in lieu of any and all other rights and remedies that the Indemnitees and Buyer Indemnitees may have under this
Agreement for monetary relief after the Closing Date, with respect to: (i) any breach of or failure to perform any covenant, agreement, or representation or warranty set forth in this Agreement; or (ii) the assets, liabilities, obligations,
business, or operations of ExRes or any of the Significant Subsidiaries, as the case may be. 
  
 (c) Notwithstanding anything to the contrary in this Agreement, no Party (including an Indemnitee) shall be entitled to recover from any other Party (including an Indemnifying Party), for any Damages under this
Agreement caused by the gross negligence or willful misconduct of a Party or Indemnitee. Except with respect to Third Party Claims made against any Indemnitee, no Party shall have any indemnification obligation under this Article VII to any other
Person with respect to any Damages consisting of incidental, indirect, consequential or punitive damages or lost profits. 
  
 (d) If any Indemnitee receives notice of the assertion of any claim or of the commencement of any Action made or brought by any Person who is not a Party
or any Affiliate of a Party (a “Third Party Claim”) with respect to which indemnification is to be sought from an Indemnifying Party, the Indemnitee shall give such Indemnifying Party reasonably prompt written notice thereof, but in
any event such notice shall be given no later than 20 calendar days 
  

 67 

 after the Indemnitee’s receipt of notice of such Third Party Claim. Such notice shall describe the nature of the
Third Party Claim in reasonable detail and shall indicate the estimated amount, if practicable, of the Damages that has been or may be sustained by the Indemnitee. The Indemnifying Party will have the right to participate in or, by giving written
notice to the Indemnitee, to elect to assume the defense of any Third Party Claim at such Indemnifying Party’s expense and by such Indemnifying Party’s own counsel; provided, that the counsel for the Indemnifying Party who shall conduct
the defense of such Third Party Claim shall be reasonably satisfactory to the Indemnitee. The Indemnitee shall cooperate in good faith in such defense at such Indemnitee’s own expense. If an Indemnifying Party elects not to assume the defense
of any Third Party Claim, the Indemnitee may compromise or settle such Third Party Claim over the objection of the Indemnifying Party, which settlement or compromise shall conclusively establish the Indemnifying Party’s liability pursuant to
this Agreement. 
  
 (i) If, within 20 calendar days after an
Indemnitee provides written notice to the Indemnifying Party of any Third Party Claim, the Indemnitee receives written notice from the Indemnifying Party that such Indemnifying Party has elected to assume the defense of such Third Party Claim as
provided in Section 7.2(d), the Indemnifying Party will not be liable for any legal expenses subsequently incurred by the Indemnitee in connection with the defense thereof; provided, however, that if the Indemnifying Party shall fail to take
reasonable steps necessary to defend diligently such Third Party Claim within 20 calendar days after receiving notice from the Indemnitee that the Indemnitee believes the Indemnifying Party has failed to take such steps, the Indemnitee may assume
its own defense and the Indemnifying Party shall be liable for all reasonable expenses thereof. 
  
 (ii) Without the prior written consent of the Indemnitee, the Indemnifying Party shall not enter into any settlement of any Third Party Claim that would
lead to liability or create any financial or other obligation on the part of the Indemnitee for which the Indemnitee is not entitled to indemnification hereunder. If a firm offer is made to settle a Third Party Claim without leading to liability or
the creation of a financial or other obligation on the part of the Indemnitee and the Indemnifying Party desires to accept and agree to such offer, the Indemnifying Party shall give written notice to the Indemnitee to that effect. If the Indemnitee
fails to consent to such firm offer within 20 calendar days after its receipt of such notice, the Indemnifying Party shall be relieved of its obligations to defend such Third Party Claim and the Indemnitee may contest or defend such Third Party
Claim. In such event the maximum liability of the Indemnifying Party as to such Third Party Claim will be the amount of such settlement offer plus reasonable costs and expenses paid or incurred by the Indemnitee up to the date of said notice.

  
 (e) Any claim by an Indemnitee on account of Damages for which
indemnification is available under this Article VII that does not result from a Third Party Claim (a “Direct Claim”) shall be asserted by giving the Indemnifying Party written notice thereof, stating the nature of such claim in
reasonable detail, but in any event such notice shall not be given later than 20 calendar days after the Indemnitee becomes aware of such Direct Claim, and the Indemnifying Party shall have a period of 20 calendar days within which to respond to
such Direct Claim. If the Indemnifying Party does not respond within such 20 calendar day period, the Indemnifying Party shall be deemed to have accepted such Direct Claim. If the Indemnifying Party rejects such Direct Claim, the Indemnitee will be
free to seek enforcement of its right to indemnification under this Agreement. 
  

 68 

 (f) If the amount of any Damages for which an indemnification payment is made under this Article VII, at
any time subsequent to the making of an indemnity payment in respect thereof, is reduced by recovery, settlement or otherwise under or pursuant to any insurance coverage, or pursuant to any claim, recovery, settlement or payment by, from or against
any other entity, the amount of such reduction, less any costs, expenses or premiums incurred in connection therewith (together with interest thereon from the date of payment thereof by the insurer or third-party to the date of repayment at the
“prime rate” as published in The Wall Street Journal) shall promptly be repaid by the Indemnitee to the Indemnifying Party. To the extent that the indemnification cap contemplated by Section 7.5 has been reached or claims are pending that
would cause such cap to be reached, this Section 7.2(f) shall have no further effect with respect to additional claims that are subject to such cap. 
  
 (g) Notwithstanding anything to the contrary in this Section 7.2, a failure to give timely notice as provided in this Section 7.2 shall not affect the
rights or obligations of any Party hereunder except if, and only to the extent that, as a result of such failure, the Party that was entitled to receive such notice was materially prejudiced as a result of such failure. 
  
 7.3 Insurance and Indemnity Proceeds. To the extent that any of the
indemnification obligations of any Indemnifying Party pursuant to this Article VII are covered by insurance (other than insurance paid for by Buyer or its Affiliates or, after the Closing, ExRes or any Significant Subsidiary) or any right to
indemnification held by any Indemnitee (other than pursuant to this Article VII) (the “Other Indemnification Rights”), such Indemnitee shall be entitled to indemnification pursuant to this Article VII only with respect to the amount
of Damages that is in excess of the cash proceeds actually received by such Indemnitee pursuant to such insurance or right to indemnification. Such Indemnitee shall use Commercially Reasonable Efforts to collect at the Indemnifying Party’s
expense all amounts due to such Indemnitee pursuant to any such insurance or right to indemnification. If such Indemnitee receives such cash insurance or indemnification proceeds prior to the time a Claim is paid, then the amount payable by the
Indemnifying Party pursuant to such Claim shall be reduced by the amount of such proceeds. If such Indemnitee receives such cash insurance or indemnification proceeds after such Claim has been paid, then upon the receipt by the Indemnitee of any
such cash proceeds, up to the amount of Damages incurred by such Indemnitee with respect to such Claim, such Indemnitee shall remit to the Indemnifying Party an amount equal to the lesser of (i) the amount of such cash proceeds (net of reasonable
expenses) or (ii) the amount that was previously paid by the Indemnifying Party to such Indemnitee in satisfaction of such Claim. If the Indemnitee refuses to collect, fails to collect or otherwise fails to use Commercially Reasonable Efforts to
collect all amounts due to such Indemnitee pursuant to any such insurance or right to indemnification, then the Indemnitee shall assign its Other Indemnification Rights to the Indemnifying Party or provide the Indemnifying Party with a power of
attorney permitting the Indemnifying Party to enforce such Other Indemnification Rights on the Indemnitee’s behalf or the Indemnifying Party shall be subrogated to such Other Indemnification Rights of the Indemnitee; provided however, that if
such Other Indemnification Rights cannot be assigned and a power of attorney cannot be provided and the Indemnifying Party cannot receive such subrogation, then, in either case, upon the Indemnifying Party’s written request, the Indemnitee

  

 69 

 shall use reasonable efforts to cause its Affiliates and/or Subsidiaries to pursue in a reasonable manner all such rights
and remedies that the Indemnitee and its Affiliates and/or Subsidiaries may have under such Other Indemnification Rights; provided, further, that to the extent the Indemnitee and its Affiliates and/or Subsidiaries would not be required under any
pre-existing contractual obligation or applicable fiduciary law principles to pursue such Other Indemnification Rights and/or remedies, any reasonable out-of-pocket cost or expense incurred by the Indemnitee and its Affiliates and/or Subsidiaries in
connection with such pursuit of rights and/or remedies shall be solely for the account of the Indemnifying Party, who will promptly reimburse the Indemnitee for all such costs and expenses. 
  
 7.4 Characterization. The Parties agree to report any payment made
pursuant to this Article VII or Section 5.8(g) as an adjustment to the purchase price for the ExRes Shares for federal income tax reporting purposes, unless otherwise required by Applicable Law. To the extent that a payment under those sections
referenced in this Section 7.4 is owing to one or more members of the Buyer Indemnitees, all such payments shall be made to Buyer. If any Taxing Authority challenges such characterization and asserts that there is Tax due in respect of any payments
made pursuant to those sections referenced in this Section 7.4, the payor of such payment otherwise required under those sections referenced in this Section 7.4 shall make an additional payment to the recipient of such payments so that the after-Tax
amount received by the recipient of such payments equals the amount of payment otherwise required under those sections referenced in this Section 7.4. 
  
 7.5 Limits; Deductible. Notwithstanding anything in this Agreement to the contrary, but subject to the other provisions of this Article VII:

  
 (a) Except as provided in Section 7.5(a)(iii) below, the
Selling Stockholders shall have no obligation to make indemnification payments to the Buyer Indemnitees under Sections 5.8(g) (other than Section 5.8(g)(i)(z)), 7.1(a)(i), 7.1(a)(iii), and Section 7.1(a)(iv)(K) of more than $200.0 million in the
aggregate. 
  
 (i) If the aggregate of all indemnity claims under
Sections 5.8(g) (other than Section 5.8(g)(i)(z)), 7.1(a)(i), 7.1(a)(iii), and Section 7.1(a)(iv)(K) is greater than $200 million, and claims are made under Sections 5.8(g)(ii) or 5.8(g)(iii), then the Selling Stockholders shall be obligated to make
additional payments of some portion of the Shared Indemnity Amount, if any, as provided in Section 7.5(a)(iii) below. 
  
 (ii) Shared Indemnity Amount shall be determined as follows: 
  
 A = the total of all indemnity claims under Sections 5.8(g), 7.1(a)(i), 7.1(a)(iii), and Section 7.1(a)(iv)(K), but excluding claims under Sections
5.8(g)(i)(z) 
  
 B = the total of all indemnity claims under
Sections 5.8(g)(ii) and 5.8(g)(iii) 
  
 C = A – B

  
 If C is less than $200.0 million, then 
  

 70 

 D = $200.0 million – C 
  
 If C is equal to or greater than $200.0 million, then D = zero 
  
 Shared Indemnity Amount = B – D 
  
 (iii) The Selling Stockholders shall be obligated to pay 50% of the Shared
Indemnity Amount for Shared Indemnity Amounts up to $50.0 million. In the event that the Shared Indemnity Amount exceeds $50.0 million, the Selling Stockholders shall be obligated to pay 50% of the Shared Indemnity Amount up to $50.0 million and
then 100% of all amounts of the Shared Indemnity Amount that are in excess of $50.0 million shall be paid to Buyer by the Selling Stockholders. For the avoidance of doubt, it is understood and agreed that Buyer shall never be obligated to bear more
than $25.0 million of the Shared Indemnity Amount. 
  
 Examples of the application
of this Section 7.5 (a) are set forth in Schedule 7.5. 
  
 (b) The Selling Stockholders shall have no obligation to indemnify the Buyer Indemnitees for any Damages under Sections 5.8(g) (other than Section 5.8(g)(i)(z)), 7.1(a)(i) or 7.1(a)(iii) unless: (i) the indemnified amount that would be
payable by the Selling Stockholders with respect to any given indemnifiable claim or series of related claims exceeds $25,000 (together with up to $75,000 payable by Buyer pursuant to Section 7.1(a)(iv)(K), “Includable Claims”); and
(ii) the aggregate amount for all Includable Claims exceeds $2.0 million, and then only to the extent of any such excess over $2.0 million. 
  
 (c) The Buyer Indemnitees may not make claims for indemnification under Section 7.1(a)(iv)(J) after the fifth anniversary of the Closing Date. 

 
 ARTICLE VIII 
  
 TERMINATION 
  
 8.1 Termination. 
  
 (a) This Agreement may be terminated at any time prior to the Closing Date
by mutual written consent of the Stockholders’ Representative and Buyer. 
  
 (b) This Agreement may be terminated by the Selling Stockholders or Buyer, if: (i) any Governmental Authority shall have issued an Order permanently restraining, enjoining or otherwise prohibiting the Closing, and
such Order shall have become final and nonappealable; (ii) any Applicable Law shall have been enacted or issued, which, directly or indirectly, prohibits the consummation of the Closing; (iii) the closing conditions set forth in Article VI are not
substantially satisfied by March 31, 2005; or (iv) the Closing contemplated hereby shall have not occurred on or before March 31, 2005 (the “Termination Date”); provided, that if any of Buyer’s Required Regulatory
Approvals or Seller’s Required Regulatory Approvals have not been obtained, diligent efforts are being undertaken to obtain such approval, authorization or consent, and all other conditions provided for in Article VI have been satisfied,
waived, or are then capable of being satisfied but for the delay in Closing, then at the election of either Party the references in the foregoing sentence to March 31, 2005 shall be extended for up to 90 calendar 
  

 71 

 days and this Agreement may not be terminated so long as such diligent efforts continue; and provided, further, that the
right to terminate this Agreement under clause (iii) of this Section 8.1(b) shall not be available to any Party whose failure to fulfill any obligation under this Agreement has been the cause of, or resulted in, the failure of the Closing to occur
on or before such date. 
  
 (c) Except as otherwise provided in
this Agreement, this Agreement may be terminated by Buyer if any of Buyer’s Required Regulatory Approvals, the receipt of which is a condition to the obligation of Buyer to consummate the Closing as set forth in Section 6.1(d), shall have been
denied (and a petition for rehearing or refiling of an application initially denied without prejudice shall also have been denied). 
  
 (d) This Agreement may be terminated by the Selling Stockholders, if any of Sellers’ Required Regulatory Approvals, the receipt of which is a
condition to the obligation of the Selling Stockholders to consummate the Closing as set forth in Section 6.2(d), shall have been denied (and a petition for rehearing or refiling of an application initially denied without prejudice shall also have
been denied). 
  
 (e) This Agreement may be terminated by Buyer,
in its sole discretion, if there has been a violation or breach by the Selling Stockholders of any covenant, representation or warranty contained in this Agreement that has resulted in an ExRes Material Adverse Effect (a “Seller
Default”) and such Seller Default is not cured by the earlier of the Closing Date or 45 calendar days after receipt by the Stockholders’ Representative of written notice specifying particularly such Seller Default, and such Seller
Default has not been waived by Buyer. If, prior to the Closing, there is a Seller Default not so cured, Buyer shall have the right to either: (i) terminate this Agreement; or (ii) subject to Section 10.1, proceed to Closing and make a claim after
Closing under Article VII. 
  
 (f) This Agreement may be
terminated by the Selling Stockholders, in their sole discretion, if there has been a violation or breach by Buyer of any covenant, representation or warranty contained in this Agreement that has resulted in a Buyer Material Adverse Effect (a
“Buyer Default”) and such Buyer Default is not cured by the earlier of the Closing Date or the date 45 calendar days after receipt by Buyer of written notice specifying particularly such Buyer Default, and such Buyer Default has not
been waived by the Selling Stockholders. If, prior to the Closing, there is a Buyer Default not so cured, the Selling Stockholders shall have the right to either: (i) terminate this Agreement; or (ii) subject to Section 10.1, proceed to Closing and
make a claim after Closing under Article VII. 
  
 8.2 Procedure
and Effect of Termination. 
  
 (a) Except for the obligations
under this Article VIII, Article IX and Article X (other than Section 10.3), if this Agreement is terminated under Section 8.1, then, except as provided in this Section 8.2, all further obligations of the Parties under this Agreement will terminate.

  
 (b) Subject to Section 10.1(b)(iii), if Buyer or the Selling
Stockholders terminate this Agreement pursuant to Section 8.1(e) or 8.1(f), as the case may be, then the rights of the non-breaching Party(ies) to pursue all legal and equitable remedies for Damages such Party(ies) suffer will survive such
termination unimpaired. 
  

 72 

 (c) If Buyer delivered a notice to Exelon under Section 5.31 and this Agreement is terminated by Buyer
pursuant to Section 8.1(e), the Selling Stockholders will reimburse Buyer for all amounts for which Buyer reimbursed Independence and SIFC under Section 5.31. 
  

ARTICLE IX 
  
 THE STOCKHOLDERS’ REPRESENTATIVE 
  
 9.1 The Stockholders’ Representative. 
  
 (a) The Selling Stockholders hereby authorize, direct and appoint Exelon (in such capacity, the “Stockholders’ Representative”) to
act as sole and exclusive agent, attorney-in-fact and representative of the Selling Stockholders, with full power of substitution with respect to all matters under this Agreement, including determining, giving and receiving notices and processes
hereunder, receiving distributions of the Purchase Price to or for the benefit of the Selling Stockholders, contesting and settling any and all claims for payment or indemnification pursuant to Article V or VII, resolving any other disputes
hereunder, performing the duties expressly assigned to Exelon hereunder and to engage and employ agents and representatives and to incur such other expenses as Exelon shall reasonably deem necessary or prudent in connection with the foregoing.
Exelon shall have the sole and exclusive right on behalf of any Selling Stockholder to take any action or provide any waiver, or receive any notice with respect to any claims for payment or indemnification under Article V or VII and to settle any
claim or controversy arising with respect thereto. Any such actions taken, exercises of rights, power or authority, and any decision or determination made by Exelon, shall be absolutely and irrevocably binding on each Selling Stockholder as if such
Selling Stockholder personally had taken such action, exercised such rights, power or authority or made such decision or determination in such Selling Stockholder’s individual capacity, and no Selling Stockholder shall have the right to object,
dissent, protest or otherwise contest the same. Any action required to be taken by the Selling Stockholders hereunder or any action which the Selling Stockholders, at their election, have the right to take hereunder, shall be taken only by Exelon
and no Selling Stockholder acting on its own shall be entitled to take any such action. All deliveries and payments to be made by Buyer to any Selling Stockholder hereunder shall be made exclusively to Exelon on behalf of the Selling Stockholders
and any delivery or payment so made to Exelon shall constitute full performance of the obligations hereunder of Buyer to the Selling Stockholders. Buyer shall not be liable for allocation of particular deliveries and payments among the Selling
Stockholders. 
  
 (b) The appointment of Exelon as each Selling
Stockholder’s attorney-in-fact revokes any power of attorney heretofore granted that authorized any other Person or Persons to represent such Selling Stockholder with regard to this Agreement, the ExRes Shares and the transactions contemplated
hereby. The appointment of the Stockholders’ Representative as attorney-in-fact pursuant hereto is coupled with an interest and is irrevocable. The obligations of each Selling Stockholder pursuant to this Agreement: (i) will not be terminated
by operation of law, liquidation, dissolution, bankruptcy, insolvency or similar event with respect to such Selling 
  

 73 

 Stockholder or any proceeding in connection therewith, or any other event; and (ii) shall survive the delivery of an
assignment by any Selling Stockholder of the whole or any fraction of its interest in any payment due to it under this Agreement. 
  
 (c) Exelon hereby accepts the foregoing appointment and agrees to serve as the Stockholders’ Representative, subject to the provisions hereof, for
the period of time from and after the date hereof without compensation except for the reimbursement from the Selling Stockholders of reasonable out of pocket expenses incurred by Exelon in its capacity as such. 
  
 (d) The provisions of this Article IX shall in no way impose any liabilities
or obligations on Buyer. In particular, notwithstanding any notice received by Buyer to the contrary and absent bad faith or willful misconduct, Buyer shall be fully protected in relying upon and shall be entitled to rely upon, shall have no
liability or obligations to the Selling Stockholders with respect to actions, decisions and determinations of the Stockholders’ Representative and shall be entitled to assume that all actions, decisions and determinations of the
Stockholders’ Representative are fully authorized by all of the Selling Stockholders. 
  
 (e) The Buyer may conclusively and absolutely rely, without inquiry, and until the receipt of written notice of a change of the Stockholders’ Representative under Section 9.1, may continue to rely, without
inquiry, upon the action of the Stockholders’ Representative as the action of each Selling Stockholder in all matters referred to in this Agreement. The Selling Stockholders shall indemnify the Buyer for all Damages incurred by it and its
Affiliates arising out of disputes between the Selling Stockholders or between a Selling Stockholder and the Stockholders’ Representative. 
  
 ARTICLE X 
  
 MISCELLANEOUS PROVISIONS 
  
 10.1 Amendment and Modification. 
  
 (a) Subject to Applicable Law, this Agreement may be amended, modified or supplemented only by written agreement of the Selling Stockholders and Buyer. 
  
 (b) Notwithstanding the foregoing, if a Party becomes aware at any time before the Closing Date that a disclosure schedule
previously delivered by such Party was inaccurate or incomplete when delivered or has become inaccurate or incomplete as a result of subsequent events, such Party shall deliver to the other Parties no later than ten Business Days after such
discovery (but in any event no later than five calendar days prior to the Closing Date) an amendment or supplement to such schedule; provided, however, that: 
  

(i) if such amendment or supplement is based on events or matters that arose before the date of this Agreement, no such amendment or supplement shall
be given effect for purposes of determining the fulfillment of the condition precedent set forth in Section 6.1(j), unless the Selling Stockholders agree to indemnify the Buyer Indemnitees for all Damages with respect to such events or matters;

  

 74 

 (ii) if such amendment or supplement is based on events or matters that arise after the date of this
Agreement and that are expressly permitted to occur under Section 5.1, such amendment or supplement shall be immediately effective and the Schedules shall be read for all purposes as so amended or supplemented; 
  
 (iii) if such amendment or supplement is based on events or matters that
arise after the date of this Agreement, such events or matters are not expressly permitted under Section 5.1 and such events or matters would reasonably be expected to result in Damages (if the Closing were to occur) to the Buyer Indemnitees of
greater than or equal to $5.0 million (or $2.0 million if the Selling Stockholders do not exercise their option under clause (iv) below), Buyer or the Selling Stockholders may terminate this Agreement upon five Business Days prior written notice to
the other Parties in which case no Party shall have any liability or obligation to any other Party (except to the extent a Party is otherwise in breach of this Agreement); 
  
 (iv) if such amendment or supplement is based on events or matters that arise after the date of this Agreement, such events
or matters are not expressly permitted under Section 5.1 and such events or matters would reasonably be expected to result in Damages (if the Closing were to occur) to the Buyer Indemnitees of greater than $2.0 million and less than $5.0 million, at
the Selling Stockholders’ option, such amendment or supplement shall be given effect for purposes of determining the fulfillment of the condition precedent set forth in Section 6.1(j) if the Selling Stockholders agree to indemnify the Buyer
Indemnitees for all Damages with respect to such events or matters; and 
  
 (v) if such amendment or supplement is based on events or matters that arise after the date of this Agreement, such events are not expressly permitted under Section 5.1, and such events or matters would reasonably be
expected to result in Damages (if the Closing were to occur) to the Buyer Indemnitees of less than $2.0 million, such amendment or supplement shall be given effect for determining the fulfillment of the condition precedent set forth in Section
6.1(j) and the Selling Stockholders shall indemnify the Buyer Indemnitees for all Damages with respect to such events or matters. 
  
 (c) Only such events or matters or series of related events or matters that are reasonably expected to constitute liabilities or obligations exceeding
$50,000 may be counted in determining whether the Selling Stockholders may exercise their right to proceed to Closing pursuant to clauses (iii), (iv) and (v) of Section 10.1(b). 
  
 10.2 Waiver of Compliance; Consents. Except as otherwise provided in this Agreement, any failure of any of the
Parties to comply with any obligation, covenant, agreement or condition in this Agreement may be waived by the Party entitled to the benefits thereof only by a written instrument signed by the Party granting such waiver, but such waiver of such
obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent failure to comply therewith. 
  
 10.3 Survival of Indemnification, Representations and Warranties. 
  
 (a) The representations and warranties set forth in Section 3.18 (captioned “Compliance with Environmental Laws”),
shall survive for a period of three years. The 
  

 75 

 representations and warranties set forth in Section 3.2 (captioned “Authorization; Validity”), Section 3.3
(captioned “Consents and Approvals; No Conflicts”) and Section 3.4 (captioned “Capitalization”) shall survive the Closing indefinitely. The representations and warranties set forth in Section 3.9 (captioned “Taxes”) and
in Section 3.12 (captioned “ERISA”) shall survive for a period that is 90 calendar days after the applicable statute of limitations (including applicable extensions). All other representations and warranties contained in this Agreement
shall survive the Closing but shall terminate and expire at the close of business on the date that is 18 months after the Closing Date. All covenants and agreements, other than the covenant set forth in Section 5.8(g) (captioned “Tax
Indemnification”), the survival of which is governed by this Section 10.3, shall be perpetual, unless otherwise specified. 
  
 (b) Except as otherwise provided in this Agreement, indemnities herein shall survive the Closing and shall be perpetual; provided, however, that: (i) the
indemnity provided under Section 7.1(a)(iv)(E) shall survive the Closing for the life of Sithe’s investment in K Road and Sithe’s obligations under the K Road Guarantee; (ii) the indemnity provided under Section 7.1(a)(iv)(F) shall survive
the Closing for the life of the Dexter Lease; and the indemnity provided under Section 7.1(a)(iv)(G) shall survive the Closing until the earlier to occur of either (A) the expiration of the applicable statute of limitations or (B) with respect to
the indemnity relating to POSDEF, the earlier of: (x) the entry by FERC of a final, binding, non-appealable determination granting that POSDEF did not lose its QF Status during the period after December 18, 2000 as a result of Exelon’s indirect
acquisition of its interest in Sithe or (y) the effective date of the settlement filed in FERC Docket Nos. EL04-26 and QF85-311 and, with respect to the indemnity relating to Luz, the earlier of: (x) the entry by FERC of a final, binding,
non-appealable determination granting that Luz did not lose its QF Status during the period after December 18, 2000 as a result of Exelon’s indirect acquisition of its interest in Sithe to Luz or (y) the effective date of the settlement filed
in FERC Docket Nos. EL04-26 and QF86-734; and (iii) the indemnity provided under Section 5.8(g) shall survive the Closing until the date that is 90 days after the expiration of the applicable statute of limitations (including applicable extensions).

  
 10.4 Notices. All notices and other communications

 77 

 AS PROVIDED IN SECTION 7.2(c), NEITHER PARTY NOR ITS AFFILIATES SHALL SEEK OR BE LIABLE FOR ANY PUNITIVE OR CONSEQUENTIAL
DAMAGES, INCLUDING LOSS OF REVENUE OR INCOME, OR LOSS OF BUSINESS REPUTATION OR OPPORTUNITY RELATING TO ANY BREACH OR ALLEGED BREACH OF THIS AGREEMENT. 
  
 10.7 Governing Law, Consent to Jurisdiction, Etc. 
  
 (a) THIS AGREEMENT SHALL BE CONSTRUED, PERFORMED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT GIVING EFFECT TO ITS PRINCIPLES
OR RULES OF CONFLICT OF LAWS TO THE EXTENT SUCH PRINCIPLES OR RULES WOULD REQUIRE OR PERMIT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION. 
  
 (b) Each of the Parties hereby irrevocably and unconditionally submits, for itself and its property, to the exclusive jurisdiction of any court of the
State of New York sitting in Manhattan or any Federal court of the United States of America sitting in the Southern District of New York and any appellate court from any thereof, in any Action arising out of or relating to this Agreement or the
Transactions or for recognition or enforcement of any judgment relating to such transactions, and each of the parties hereby irrevocably and unconditionally agrees that all claims in respect of any such Action shall be heard and determined in such
court of the State of New York or, to the extent permitted by Applicable Law, in such Federal court. Each of the Parties agrees that a final judgment in any such Action shall be conclusive and may be enforced in other jurisdictions by suit on the
judgment or in any other manner provided by law. 
  
 (c) Each of
the Parties hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any Action arising out of or related to this Agreement
or the Transactions in any such New York state or federal court. Each of the Parties hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such Action in any such court. Each of
the Parties shall designate and appoint an agent for the service of process in the State of New York in connection with any dispute arising under this Agreement, and agrees to consider any legal process or any demand or notice made or served on such
agent as being made to it. 
  
 (d) THE PARTIES EACH HEREBY AGREE
TO WAIVE THEIR RESPECTIVE RIGHTS TO JURY TRIAL OF ANY DISPUTE BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY OTHER AGREEMENTS RELATING HERETO OR ANY DEALINGS AMONG THEM RELATING TO THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. The scope of
this waiver is intended to be all encompassing of any transaction contemplated hereby, including Contract claims, tort claims, breach of duty claims, and all other material inducement to enter into a business relationship and that they will continue
to rely on the waiver in their related future dealings. Each Party further represents and warrants that it has reviewed this waiver with its legal counsel, and that each knowingly and voluntarily waives its jury trial rights following consultation
with legal counsel. NOTWITHSTANDING ANYTHING TO THE CONTRARY HEREIN, THIS WAIVER IS IRREVOCABLE, MEANING THAT IT MAY NOT BE MODIFIED ORALLY OR IN 
  

 78 

 WRITING, AND THE WAIVER WILL APPLY TO ANY AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT OR TO ANY
OTHER DOCUMENTS OR AGREEMENTS RELATING HERETO. In the event of an Action, this Agreement may be filed as a written consent to trial by a court. 
  
 10.8 Professional Fees and Expenses. Except as expressly set forth in this Agreement, each Party shall pay all legal, accounting, and other fees
and expenses incurred by such Party in connection with this Agreement and the transactions contemplated thereby. The Selling Stockholders will promptly reimburse Buyer for any such fees or expenses incurred prior to Closing in connection with the

this Agreement. 
  
 10.11 Schedules and Exhibits. Except as
otherwise provided in this Agreement, all Exhibits and Schedules referred to in this Agreement are intended to be and hereby are specifically made a part of this Agreement. 
  
 10.12 Entire Agreement. This Agreement, including the Exhibits, Schedules, documents, certificates and instruments
referred to in this Agreement or therein, embody the entire agreement and understanding of the Parties in respect of the transactions contemplated by this Agreement. There are no restrictions, promises, representations, warranties, covenants or
undertakings, other than those expressly set forth or referred to in this Agreement or therein. It is expressly acknowledged and agreed that there are no restrictions, promises, representations, warranties, covenants or undertakings contained in any
material made available to Buyer pursuant to the terms of the Confidentiality Agreement. This Agreement supersedes all prior agreements and understandings between the Parties other than the Confidentiality Agreement with respect to such
transactions. 
  
 10.13 Severability. Any provision of this
Agreement that is invalid or unenforceable in any jurisdiction shall be ineffective to the extent of such invalidity or unenforceability without invalidating or rendering unenforceable the remaining provisions hereof, and any such invalidity or
unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction; provided that if any provision of this Agreement, as applied to any Party or to any circumstance, is adjudged by a
Governmental Authority, arbitrator, or mediator not to be enforceable in accordance with its terms, the Parties agree that the Governmental Authority, arbitrator, or mediator making such determination will have the power to modify the provision in a
manner consistent with its objectives such that it is enforceable, and/or to delete specific words or phrases, and in its reduced form, such provision will then be enforceable and will be enforced.

 10.14 Third Party Beneficiaries. Other than those Persons entitled to indemnity under Article VII,
there are no third party beneficiaries having rights under or with respect to this Agreement. 
  
 10.15 Schedules. 
  
 (a)
If there is any inconsistency between the statements in the body of this Agreement and those in the Schedules (other than an exception expressly set forth in the Schedules with respect to a specifically identified representation or warranty), the
statements in the body of this Agreement will control. 
  
 (b) The
disclosures in the Schedules relate only to the representations and warranties in the Section or paragraph of the Agreement to which they expressly relate and not to any other representation or warranty in this Agreement. 
  
 (c) Nothing in the Schedules will be deemed adequate to disclose an exception
to a representation or warranty made herein, unless the Schedules identify the exception with reasonable particularity. 
  
 (d) Certain items are listed in the Schedules for informational purposes because they do not rise above applicable materiality thresholds and, as such,
are not required to be disclosed in such Schedules. In no event shall the listing of such items in the Schedules be deemed or interpreted to broaden or otherwise amplify the representations and warranties, covenants or agreements contained in this
Agreement, and nothing in the Schedules shall influence the construction or interpretation of any of the representations and warranties contained in this Agreement. The headings contained in the disclosure schedules are for convenience of reference
only and shall not be deemed to modify or influence the interpretation of the information or the standard of materiality contained in the Schedules or this Agreement. 
  
 (e) With respect to any event or matter for which Buyer has been indemnified pursuant to Section 7.1(a)(iv), the Selling
Stockholders shall not be required to schedule any items in connection with any of the representations and warranties in Article III. To the extent such event or matter is covered by the indemnity as set forth in Section 7.1(a)(iv), the absence of
the disclosure of any such event or matter shall not form the basis of any claim for any breach of any representation or warranty in Article III. 
  
 10.16 Time. Time is of the essence in the performance of this Agreement. 
  
 10.17 Construction. The Parties have participated jointly in the negotiation and drafting of this Agreement. If an
ambiguity or question of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the Parties and no presumption or burden of proof will arise favoring or disfavoring any Party because of the authorship of any
provision of this Agreement. Any reference to any federal, state, local, or foreign Law will be deemed also to refer to Law as amended and all rules and regulations promulgated thereunder, unless the context requires otherwise. The words “this
Agreement,” “herein,” “hereof,” “hereby,” “hereunder,” and words of similar import refer to this Agreement as a whole and not to any particular subdivision unless expressly so limited. The Parties intend
that each representation, warranty, and covenant contained herein will have independent significance. If any Party has breached any 
  

 80 

 representation, warranty, or covenant contained herein in any respect, the fact that there exists another representation,
warranty or covenant relating to the same subject matter (regardless of the relative levels of specificity) which the Party has not breached will not detract from or mitigate the fact that the Party is in breach of the first representation,
warranty, or covenant. 
  
 10.18 Joint and Several
Obligations. Notwithstanding anything to the contrary in this Agreement, the covenants and obligations of, and the representations and warranties made by or attributable to, any Selling Stockholder pursuant to this Agreement will be deemed to be
made by and attributable to each Selling Stockholder, jointly and severally, and the Buyer will have the right to pursue remedies against any one or more Selling Stockholder, without any obligation to give notice to or pursue all Selling
Stockholders or to give notice to or pursue any individual Selling Stockholder before pursuing any other Selling Stockholders. 
  
 10.19 Electronic Signatures. 
  
 (a) Notwithstanding the Electronic Signatures in Global and National Commerce Act (15 U.S.C. Sec. 7001 et. seq.), the Uniform Electronic
Transactions Act, or any other Law relating to or enabling the creation, execution, delivery, or recordation of any Contract or signature by electronic means, and notwithstanding any course of conduct engaged in by the Parties, no Party will be
deemed to have executed this Agreement or any other document contemplated hereby (including any amendment, waiver or other change thereto) unless and until such Party shall have executed such document on paper by a handwritten original signature or
any other symbol executed or adopted by a Party with current intention to authenticate such document contemplated. 
  
 (b) Delivery of a copy of this Agreement or any other document contemplated hereby bearing an original signature by facsimile transmission (whether
directly from one facsimile device to another by means of a dial-up connection or whether mediated by the worldwide web), by electronic mail in “portable document format” (“.pdf”) form, or by any other electronic means intended
to preserve the original graphic and pictorial appearance of a document, will have the same effect as physical delivery of the paper document bearing the original signature. “Originally signed” or “original signature” means or
refers to a signature that has not been mechanically or electronically reproduced.

 Re: Amendment of Stock Purchase Agreement—Special Payroll Payment 
  
 Gentlemen: 
  
 Reference is made
to that certain Stock Purchase Agreement, dated as of November 1, 2004, as amended by those certain letter agreements dated December 2, 2004 and December 31, 2004 (the “SPA”), in each case by and among Exelon SHC, Inc., Exelon New England
Power Marketing, L.P., Dynegy New York Holdings Inc. and ExRes SHC, Inc. Capitalized terms used herein without definition shall have the definitions given such terms in the SPA. 
  
 Section 6.1(e) of the SPA requires as one of Buyer’s closing conditions that ExRes and Sithe have in the aggregate at
least $25,370,000 in unrestricted cash (the “Base Unrestricted Cash Amount”) as of the Closing Date, as such amount is adjusted as provided in Section 6.1(e). Buyer has requested that ExRes and Sithe make a special payroll payment to their
employees outside the ordinary course of business for a partial payroll period ending January 31, 2005 (the “Special Payroll Payment”) and that the Base Unrestricted Cash Amount be reduced by the amount of the Special Payroll Payment made.
As such, the parties to the SPA hereby agree that, because of the $449,767 Special Payroll Payment, Section 6.1(e) of the SPA shall be amended by deleting the number $25,370,000 therefrom and replacing such number with the number $24,920,233.

 Except as amended, modified or waived hereby, the SPA remains in full force and effect and is hereby
ratified and affirmed. This letter agreement may be executed in any number of counterparts, all of which taken together shall constitute one and the same amendatory instrument, and any of the parties hereto may execute this letter agreement by
signing any such counterpart. This letter agreement shall be governed by, and construed in accordance with, the internal laws of the State of New York.

 IN WITNESS WHEREOF, the parties have duly executed this letter agreement as of the date first above
written.
