 This Termination Agreement and Release (“Agreement”) is made and entered into this 23rd day of December, 2005 (the “Signing Date”) by
and among Quachita Power, LLC, formerly known as Ouachita Power, LLC (“Quachita Power”), a Delaware limited liability company, and Dynegy Power Marketing, Inc. (“DYPM”), a Texas corporation. DYPM and Quachita Power are sometimes
referred to in this Agreement individually as a “Party” and collectively as the “Parties.” 
  
 RECITALS 
  
 A. An Amended and Restated Dependable Capacity and Conversion Services Agreement (as amended, the “Capacity and Services Agreement”) was entered into between Quachita Power and DYPM as of June 1, 2000 pursuant to which DYPM
agreed to purchase, and Quachita Power agreed to sell, certain quantities of electric energy and capacity from Quachita Power’s electric generating facility in Sterlington, Ouachita Parish, Louisiana. 
  
 B. The Parties remain bound by their obligations to each other under the
terms and conditions of the Capacity and Services Agreement, but the Parties have been engaged in discussions regarding specific arrangements whereby the Capacity and Services Agreement would be terminated in consideration for the payment of certain
sums by DYPM to Quachita Power. 
  
 C. As a consequence of those
discussions, the Parties desire to, upon satisfaction of the conditions set forth herein: (i) terminate the Capacity and Services Agreement in accordance with and subject to the provisions set forth below; (ii) execute mutual releases in
conjunction with the early termination of the Capacity and Services Agreement as set forth below; and (iii) provide for the payment of the Termination Amount (as defined below) in consideration for the termination of the Capacity and Services
Agreement and the releases set forth below. 
  
 NOW, THEREFORE,
in consideration of their mutual promises and other good and valuable consideration (the adequacy and receipt of which is hereby acknowledged), the Parties agree as follows: 
  
 1. DYPM shall pay to Quachita Power the aggregate amount of three hundred seventy million dollars ($370,000,000) (the
“Termination Amount”), subject to adjustment pursuant to the provisions of Paragraph 2(b), on the Effective Date (as defined in Paragraph 2) by wire transfer to the following account: 
  
 ABA: 053000196 
 Account Number: 000687649253 
 Account Name:
Ouachita Power Revenue 
 Reference: Dynegy Power Marketing 
  
 DYPM shall promptly provide to Quachita Power the Federal Reference Number for such wire. Once paid, the Termination Amount shall not be
refundable for any reason. 

 2. (a) DYPM shall pay the Termination Amount to Quachita Power on or before the date (the “Effective
Date”) which shall be the later of (i) December 31, 2005 and (ii) the date on which the following conditions shall be met to the reasonable satisfaction of Quachita Power (as acknowledged in writing by Quachita Power):

  
 (i) all consents and other authorizations
required to be obtained by Cogentrix Delaware Holdings, Inc. and Cogentrix Energy, Inc. under the Credit Agreement, dated as of April 14, 2005, among Cogentrix Delaware Holdings, Inc., as Borrower, Cogentrix Energy, Inc., BNP Paribas, as
Issuer, Union Bank of California, N.A., as Collateral Agent, BNP Paribas, as Administrative Agent, and the Arrangers and Lenders named therein in connection with the transactions contemplated hereby shall have been obtained; and 
  
 (ii) to the extent that any outstanding amounts are owed
under the Loan and Reimbursement Agreement, dated as of August 17, 2000 (as amended, the “Loan and Reimbursement Agreement”), among Quachita Power, as Borrower, the Lenders named therein, Bank of America, N.A., as Issuing Bank and
Administrative Agent, and Banc of America Securities LLC, as Syndication Agent, and such Loan and Reimbursement Agreement remains in full force and effect, all consents and other authorizations required to be obtained by Quachita Power under such
Loan and Reimbursement Agreement in connection with the transactions contemplated hereby shall have been obtained; and 
  
 (iii) all consents and other authorizations required to be obtained by Quachita Power or any affiliate from the Federal Energy Regulatory
Commission, including, but not limited to, any Section 203 filings, in connection with the transactions contemplated hereby or any transactions related to this Agreement, including, but not limited to, the acquisition by Cogentrix Ouachita
Holdings, Inc. of all of the membership interests in Quachita Power owned by MEP-I LLC (the “Acquisition Transaction”), shall have been obtained; and 
  

(iv) all filings required to be made by Cogentrix Ouchita Holdings, Inc. and MEP-I LLC under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (“HSR”), in connection with the consummation of the Acquisition Transaction shall have been timely made with the proper governmental authority, and any waiting period required under HSR relating to such
filings which is applicable to the consummation of the Acquisition Transaction shall have expired or been terminated. 
  
 (b) Each of the Parties shall use commercially reasonable efforts to satisfy the conditions set forth in this Paragraph 2, and to make and cause to be
made any filings with respect to consents or approvals set forth in Paragraphs 2(a)(iii) and (iv), as soon as reasonably practicable. In the event that the conditions set forth in this Paragraph 2 are not satisfied by December 31, 2005, the
Termination Payment shall be reduced pursuant to the following formula: 
  
 TP = $370,000,000.00 – (CP – [X × D]) 
  
 Where:

  

			
	 TP    =
	  	Termination Payment;

  

 2 

			
	 CP    =
	  	Capacity Payments (as such term is defined in the Capacity and Services Agreement) that are paid or that have accrued and not been paid and are not past due by DYPM to Quachita Power with
respect to periods after December 31, 2005 under the Capacity and Services Agreement (and excluding, for the avoidance of doubt, Capacity Payments with respect to November 2005 or December 2005);
		
	 X    =
	  	$60,000.00 from and including January 1, 2006, through and including February 28, 2006, and $40,000.00 from and after March 1, 2006; and
		
	 D    =
	  	The number of days between December 31, 2005 and the Effective Date.

  
 Notwithstanding the foregoing or any
other provision of this Agreement to the contrary, if the conditions set forth in this Paragraph 2 are not satisfied by March 31, 2006 (“Termination Date”) for any reason (other than the bad faith or willful misconduct of a Party),
this Agreement shall terminate and be of no further force and effect, and neither Party or any of their affiliates shall have any rights or obligations with respect to or arising out of this Agreement from and after the Termination Date. 

 
 (c) Each of the Parties shall continue to perform fully all of its
obligations under the Capacity and Services Agreement for the period (“Performance Period”) between the Signing Date and the Effective Date, including, without limitation, with respect to DYPM, its payment obligations thereunder, including
(i) obligations that have accrued and not been paid and are not past due and (ii) its obligation to pay the pro rata portion of any Capacity Payments applicable to the month in which the Capacity and Services Agreement is terminated
hereunder, which shall be in addition to its obligation to pay the Termination Amount. 
  
 3. The Capacity and Services Agreement shall terminate immediately on the Effective Date in consideration for, and subject to, the payment of the Termination Amount on or prior to such date. Except as provided in this
Agreement, none of the Parties shall have any further rights or obligations with respect to or arising out of the Capacity and Services Agreement after the Effective Date save and except for rights and obligations with respect to payment and
indemnity arising under the Capacity and Services Agreement prior to the Effective Date, provided that in the event of offsetting monetary obligations, such obligations shall be set off against each other and the Party owing any net amount following
such setoff shall pay such amount to the other Party. 
  
 4. As of
the Effective Date, but subject to the payment of the Termination Amount and, in addition, any accrued but unpaid amounts owed by DYPM under the Capacity and Services Agreement arising during the Performance Period, Quachita Power and all of its
present and former parent companies, affiliates, subsidiaries, and divisions, and its and their agents, assigns, attorneys, employees, representatives, officers, directors, predecessors and successors, and each and all of them (collectively, the
“Quachita Releasors”), release, and shall be deemed to have forever released and discharged, DYPM and all of its present and former parent companies, affiliates, subsidiaries, and divisions, and its and their agents, assigns, attorneys,
employees, representatives, officers, directors, predecessors and successors, and each and all of them (collectively, the “Dynegy Released Entities and Persons”), from any and all claims, demands and causes of action of every kind and
nature, whether known or unknown, suspected or

unsuspected, accrued or unaccrued, liquidated or unliquidated, fixed, contingent, direct, derivative or indirect, consequential, for lost profits or business
or economic loss, or otherwise, whether at common law, equitable, or statutory, whether in court, arbitration or other forum, whether based on contract, tort, express or implied warranty, breach of a duty of good faith and fair dealing, tortious
interference with prospective economic advantage, fraud, equitable estoppel, promissory estoppel, unjust enrichment, punitive damages or other cause of action or theory that the Quachita Releasors have, may have, or claim to have or hereafter may
acquire against the Dynegy Released Entities and Persons, in each case arising by reason or in respect of any act, omission, cause, matter or thing whatsoever, whether known or unknown, in connection with the Capacity and Services Agreement, and
whether arising prior to or after the Effective Date. 
  
 5. As of

Entities and Persons”), from any and all claims, demands and causes of action of every kind and nature, whether known or unknown, suspected or unsuspected, accrued or unaccrued, liquidated or unliquidated, fixed, contingent, direct, derivative
or indirect, consequential, for lost profits or business or economic loss, or otherwise, whether at common law, equitable, or statutory, whether in court, arbitration or other forum, whether based on contract, tort, express or implied warranty,

unknown, in connection with the Capacity and Services Agreement, and whether arising prior to or after the Effective Date. 
  
 6. In furtherance of the foregoing, the Parties agree as follows: 
  

(a) The Guaranty (the “Cogentrix Guaranty”) issued by Cogentrix Energy, Inc., dated October 1, 2002, in favor of DYPM, to secure certain
payment obligations of Quachita Power up to the aggregate amount of five million dollars ($5,000,000) pursuant to Section 2.6(b) of the Capacity and Services Agreement shall: (i) include and guarantee Quachita Power, LLC’s obligations
under this Agreement (subject, in all cases, to the $5,000,000 limitation of liability set forth in the Cogentrix Guaranty); and (ii) terminate irrevocably and no longer be of any force and effect immediately upon the Effective Date, and
Cogentrix Energy, Inc. shall be released from all of its obligations under the Cogentrix Guaranty immediately upon such termination. 
  
 (b) The Guaranty (the “Dynegy Guaranty”) issued by Dynegy Holdings Inc., dated April 19, 2005, in favor of Quachita Power, to secure
certain payment obligations of DYPM pursuant to Section 2.6(c) of the Capacity and Services Agreement, shall: (i) include and

guarantee DYPM’s obligations under this Agreement; and (ii) terminate irrevocably and no longer be of any force and effect immediately upon the
Effective Date, and Dynegy Holdings Inc. shall be released from all of its obligations under the Dynegy Guaranty immediately upon such termination; provided, however, that in the event that any unpaid Capacity Payments or Energy
Payments (as each such term is defined in the Capacity and Services Agreement) are due and owing on the Effective Date, the Dynegy Guaranty shall remain in effect to secure the payment by DYPM of such Capacity Payments and Energy Payments up to the
aggregate outstanding amount thereof (the “Remaining Guaranty Obligations”) until such Capacity Payments and Energy Payments shall be paid in full, at which time the Remaining Guaranty Obligations of Dynegy Holdings Inc. shall terminate
irrevocably and no longer be of any force and effect. 
  
 7. Each
of the Quachita Releasors and each of the DYPM Releasors hereby covenants, upon and following the Effective Date, not to sue or otherwise seek recovery of any amount, damage or injury in any litigation, arbitration or other forum for any claim
released under this Agreement; provided that nothing herein shall limit or release any action or claim for enforcement of this Agreement. Each of the Quachita Power Released Entities and Persons, and each of the DYPM Released Entities and
Persons may, in addition to any other rights or remedies it may have at law or in equity, plead this Agreement as a bar to any claim, or proceeding in respect of any claim, released under this Agreement. 
  
 8. Except to the extent otherwise provided in this Agreement, each of the
Parties is responsible for its own respective costs, disbursements, and attorney’s fees incurred in connection with the negotiation and execution of this Agreement. 
  
 9. If it becomes necessary for any Party to proceed against the other Party for breach of any of the terms of this Agreement
or to enforce the terms hereof, then the Party that is determined by any court of competent jurisdiction to have breached the terms hereof or failed to perform its obligations hereunder shall pay to the other Party, in addition to any other damages,
all reasonable attorneys’ fees and costs incurred by the other Party in such proceeding; provided, however, NEITHER PARTY SHALL BE LIABLE TO
THE OTHER PARTY FOR ANY INDIRECT, SPECIAL, CONSEQUENTIAL, PUNITIVE, OR EXEMPLARY
LOSS OR DAMAGE THAT MAY BE SUFFERED BY THE OTHER PARTY, INCLUDING
ANY LOST PROFITS, REVENUE, OR EARNINGS OR LOST OPPORTUNITY OR USE,
WHETHER ARISING IN CONTRACT, TORT (INCLUDING NEGLIGENCE AND STRICT LIABILITY), OR
OTHERWISE, AND EACH PARTY HEREBY RELEASES THE OTHER PARTY FROM LIABILITY
THEREFROM. THIS PARAGRAPH 9 IS NOT INTENDED AND SHALL NOT BE CONSTRUED
TO LIMIT A PARTY’S RIGHT TO RECOVER REASONABLE ATTORNEYS’ FEES,
COURT COSTS, OR OTHER COSTS AND EXPENSES INCURRED BY SUCH PARTY AS
SET FORTH IN THIS PARAGRAPH 9. NOTWITHSTANDING THE FOREGOING PROVISIONS OF THIS
SECTION 9 OR ANYTHING IN THIS AGREEMENT TO THE CONTRARY, UNTIL THE
EFFECTIVE DATE, IF ANY, THE CAPACITY AND SERVICES AGREEMENT AND THE
PARTIES’ OBLIGATIONS THEREUNDER SHALL NOT BE AMENDED, MODIFIED OR TERMINATED IN
WHOLE OR IN PART AS A RESULT OF ANY OF THE PROVISIONS
OF THIS AGREEMENT. 
  
 10. Each Party agrees that, upon and following the Effective Date, this Agreement is intended to constitute a general release, and THIS AGREEMENT IS INTENDED TO EXTEND TO CLAIMS WHICH A PARTY DOES NOT KNOW OR SUSPECT TO EXIST IN ITS FAVOR
AT THE TIME OF EXECUTING THIS AGREEMENT, WHICH IF KNOWN BY IT 

  

 5 

 
COULD HAVE MATERIALLY AFFECTED ITS SETTLEMENT WITH THE OTHER PARTY. EACH PARTY EXPRESSLY WAIVES ANY RIGHTS THAT PARTY MAY HAVE UNDER ANY APPLICABLE STATUTE
OR COMMON LAW PRINCIPLE LIMITING ANY SUCH UNKNOWN CLAIM, OR OTHERWISE CONCERNING THIS RELEASE AND/OR THE CLAIMS RELEASED HEREUNDER. 
  
 11. In making this compromise settlement and release, the Parties are each relying upon their own respective judgment and knowledge as to all aspects of
the Capacity and Services Agreement and upon the advice of their own respective attorneys. Neither of the Parties hereto shall be considered to be the drafter of this Agreement or any provision hereof for the purpose of any statute, case law or rule
of interpretation or construction that would or might cause any provision to be construed in favor of or against any Party. In making this compromise settlement and release, the Parties acknowledge that they have not relied upon the representations
or statements of the other Party other than those recitals, representations and warranties set out in this Agreement. 
  
 12. This Agreement supersedes any and all prior oral or written agreements entered into by and among the Parties concerning the termination of the
Capacity and Services Agreement and the settlement and releases herein and comprises the entire and final agreement and understanding of the Parties. This Agreement may not be amended or modified orally and any proposed amendment or modification of
this Agreement shall be effective only upon each Party’s signature of a written instrument that makes express reference to this Agreement and expressly states that it is an amendment hereof. Each of the Parties hereto represents that it has had
the advice of counsel concerning the terms and conditions of this Agreement and in entering into it; and each Party expressly assumes the risk of any mistake of fact or law relating to this Agreement. 
  
 13. Upon and following the Effective Date, this Agreement reflects the
compromise of the Parties’ respective rights under the Capacity and Services Agreement. This Agreement shall in no way be deemed or construed to constitute an admission of any liability, obligation or right by either of the Parties. 

 
 14. Upon and following the Effective Date, each Party agrees to execute
and deliver, or cause to be executed and delivered, all instruments, certificates, and documents, and to take all such other actions, as the other Party may reasonably request in order to implement and effectuate the purpose and intent of this
Agreement. 
  
 15. Each of the Parties covenants, warrants and
represents, as of the Signing Date, that:

 6 

 (c) The person executing this Agreement is fully authorized to execute this Agreement on behalf of such

 (d) Subject to Paragraph 2(a), neither this Agreement,
nor any obligation, duty or requirement hereunder, if performed as provided herein, violates or would cause a default of any agreement, contract, or indenture to which it is a party or by which it is bound, or any order of a court or other
governmental entity asserting jurisdiction; and 
  
 (e) This
Agreement represents the legal, valid and binding obligation of such Party, enforceable in accordance with its terms. 
  
 16. Each of the representations, warranties, agreements and covenants of the Parties contained in this Agreement shall survive the execution and delivery
of this Agreement and the date hereof and shall be binding upon and enforceable by the successors and assigns of the Parties. 
  
 17. Nothing in this Agreement is intended to apply to or to operate as a cancellation or release of any obligations under any agreement or contract (other

as of the Signing Date or the Effective Date. 
  
 18. This
Agreement shall be governed by and construed in accordance with the law of the State of New York, exclusive of conflicts of laws provisions that would direct the application of any other governing law.

to perform any covenants of the Buyer or Dynegy contained in this Agreement or any Ancillary Agreement. 
  
 8.3 Environmental Indemnification. Without limiting the generality of the obligations of Buyer set forth in
Section 8.2 above, Buyer and Dynegy agree, jointly and severally, to release, indemnify, defend and hold harmless the Seller Indemnified Parties from and against, and agree not to sue or join the Seller Indemnified Parties in any lawsuit
or proceeding for, any and all claims, actions, suits, demands, liabilities (including, without limitation, strict liability arising under Environmental Laws), obligations, damages, judgments, awards, penalties, settlements, fines, losses, costs,
and expenses (including, without limitation, reasonable legal fees), of any kind or nature, directly or indirectly resulting from, relating to or arising out of the following and attributable to or arising from any event, condition, circumstance,
activity, practice, incident, action or plan existing, commencing, or occurring at any time, whether prior to or after the closing, relating in any way to RRP or Termo Alpha or any of their respective assets or Business Facilities (including without
limitation the ownership, operation or use of any of the Business Facilities): 
  
 (a) Any actual or threatened violation of, liability under, non-compliance with, or environmental response obligation arising pursuant to,
any Environmental Laws; 
  
 (b) Any liability,
including, without limitation, strict liability, associated with the treatment, storage, disposal, or transportation for treatment, storage, or disposal, of Materials of Environmental Concern generated at any time by RRP, Termo Alpha or the Facility
or for which RRP or Termo Alpha arranged at any time for treatment, storage or disposal; and 
  
 (c) The presence at any time of any Materials of Environmental Concern exceeding naturally-occurring concentrations on, in, under or
affecting all or any portion of any of the Business Facilities of RRP or Termo Alpha or the Facility and any release or threatened release at any time with respect to Materials of Environmental Concern. 
  
 The obligations of the Buyer and Dynegy hereunder are not contingent upon the
assertion of a claim, directive, action or proceeding by a Governmental Authority or third party. Buyer 

  

 13 

 
and Dynegy shall be solely liable for all such environmental matters notwithstanding any Seller Indemnified Party’s potential strict liability or
alleged negligence. 
  
 8.4 Tax
Liability. Notwithstanding anything contained herein to the contrary, the Buyer shall be under no duty or obligation to indemnify the Seller for any income tax liability due to the assignment, sale or transfer of the Membership
Interests. 
  
 8.5 Survival
Periods. The representations and warranties set forth in Section 3 and Section 4 shall survive the Closing for a period of two years; provided, however, that the representations and warranties set
forth in Section 3.1 (Ownership of Membership Interests), Section 3.2 (Authority of Seller) and Section 4.2 (Authority of Buyer) shall survive the Closing indefinitely. All other covenants and agreements of the
Parties set forth in this Agreement shall survive the Closing indefinitely. 
  
 8.6 Limitations on Liability. 
  
 (a) In no event shall Seller or NRG (determined on a combined basis) have any liability or obligation with respect to claims pursuant to
Section 8.1 for any amounts in excess of the aggregate Purchase Price. 
  
 (b) In no event shall Buyer or Dynegy (determined on a combined basis) have any liability or obligation with respect to claims pursuant to
Section 8.2 or Section 8.3 for any amounts in excess of the aggregate Purchase Price. 
  
 (c) No indemnifying Party (“Indemnitor”) shall have any obligation to indemnify a Party for special, punitive, indirect
or consequential damages, lost profits or similar items, except with respect to matters involving actions, claims or other proceedings brought or asserted by third parties and then only to the extent that an indemnified party (“Indemnified
Party”) is required to pay any such damages, lost profits or similar items to such third parties. Nothing in this Agreement is intended to require the payment by the Indemnitor of duplicative, in whole or in part, indemnity payments to an
Indemnified Party. 
  
 (d) The amount of any
Losses for which indemnification is provided by an Indemnitor under Section 8.1 or Section 8.2 shall be net of (1) any amounts recovered by the Indemnified Party with respect to such Losses pursuant to any
indemnification by or indemnification agreement with any third party in excess of any associated cost to the Indemnified Party in obtaining such indemnification; (2) any insurance proceeds or other reimbursement received as an offset against
such Losses (and no right of subrogation shall accrue hereunder to any insurer or third-party indemnitor); and (3) an amount equal to the net cash tax benefit actually received attributable to such Losses. If the amount to be netted is
determined after payment by the Indemnitor of any amount, the Indemnified Party shall repay to the Indemnitor, promptly after such determination, any amount that the Indemnitor would not have had to pay pursuant to this Section 8.6 had
such determination been made at the time of payment. 
  
 (e) All indemnification payments made in accordance with this Section 8 will be treated as an adjustment to the Purchase Price, except to the extent that the Laws of a 

  

 14 

 
particular jurisdiction provide otherwise, in which case such payments shall be made in an amount sufficient to indemnify the relevant Party on an after-Tax
basis (determined by reference to actual out-of-pocket Tax liability incurred by the relevant Party). 
  
 (f) Any claim for indemnification with respect to any of such matters identified in Section 8.5 above which is not asserted by
notice given as herein provided within such specified period of survival may not be pursued and is hereby irrevocably waived after such time. 
  
 (g) No Party shall be required to pay or be liable for any Losses with respect to an individual claim (which individual claim shall
include claims arising out of the same or substantially related circumstances) under Section 8.1 or Section 8.2 unless and until the Losses for such claim exceed One Hundred Fifty Thousand Dollars ($150,000) (the “De
Minimis Amount”). 
  
 (h) Except claims
made pursuant to the Litigation Agreement for which there shall be no Deductible, no Party shall be required to pay or be liable with respect to any claim for indemnification under Section 8.1 or Section 8.2 unless and until
the aggregate amount of Losses to Buyer’s Indemnified Persons based upon, attributable to or resulting from these indemnities of Sellers exceed, in the aggregate, Six Hundred Fifty Thousand Dollars ($650,000) (the
“Deductible”), disregarding any individual claim (which individual claim shall include claims arising out of the same or substantially related circumstances) that does not exceed the De Minimis Amount applicable pursuant to
Section 8.6(g) and then only to the extent that such Losses exceed the Deductible. 
  
 8.7 Procedure for Indemnification Claims. 
  
 (a) Third Party Claims. 
  
 (i) Each Party shall, with reasonable promptness after obtaining knowledge thereof, provide the other Party or parties against whom a
claim for indemnification is to be made under this Section 8 with written notice of all third party actions, suits, proceedings, claims, demands or assessments that may be subject to the indemnification provisions of this
Section 8, (collectively, “Third Party Claims”), which notice shall include a statement of the basis of the claim for indemnification, including a summary of the facts or circumstances that form the basis for the claim,
a good faith estimate of the amount of Losses claimed by the third party and copies of any pleadings or demands from the third party. Notwithstanding the foregoing, provided that such notice is in any event given within the survival periods stated
in Section 8.5, the failure to provide such notice reasonably promptly shall not release the Indemnitor from any of its obligations under this Section 8, except to the extent that the Indemnitor is materially prejudiced by
such failure, and shall not relieve the Indemnitor from any other obligation or liability that it may have to the Indemnified Party otherwise than under this Section 8. 
  

 15 

 (ii) A potential Indemnitor shall have 30 days after its receipt of the claim notice to
notify the potential Indemnified Party in writing whether or not the potential Indemnitor agrees that the claim is subject to this Section 8 and, if so, whether the Indemnitor elects to undertake, conduct and control, through counsel of
its choosing (subject to the consent of the Indemnified Party, such consent not to be withheld unreasonably) and at its sole risk and expense, the settlement or defense of the Third Party Claim; provided, however, that if legal counsel to the
Indemnified Party determines, in writing provided to Indemnitor, that there exists or is reasonably likely to exist a conflict of interest which makes it inappropriate for the same counsel to represent both the Indemnified Party and the Indemnitor,
then the Indemnified Party shall be entitled to retain its own counsel (such counsel subject to the reasonable approval of the Indemnitor), with the reasonable costs and expenses of such counsel to be paid by the Indemnitor. 
  
 (iii) If within 30 days after its receipt of the claim
notice the Indemnitor notifies the Indemnified Party that it elects to undertake the settlement or defense of the Third Party Claim, the Indemnified Party shall cooperate reasonably with the Indemnitor in connection therewith including, without
limitation, by making available to the Indemnitor all relevant information and the testimony of employees material to the defense of the Third Party Claim. The Indemnitor shall reimburse the Indemnified Party for reasonable out-of-pocket costs
incurred in connection with such cooperation. The Indemnified Party shall be entitled to approve any proposed settlement that would impose any obligation or duty on the Indemnified Party or include a finding or admission of any violation of
applicable law on the part of the Indemnified Party, which approval shall not be unreasonably withheld. So long as the Indemnitor is diligently and in good faith contesting the Third Party Claim (1) the Indemnified Party shall be entitled to
participate in all aspects of, but not conduct or control, the settlement or defense of the Third Party Claim through counsel and advisors chosen by the Indemnified Party, at its expense, and (2) the Indemnified Party shall not pay or settle
the Third Party Claim. Notwithstanding the foregoing, the Indemnified Party shall have the right to pay or settle any Third Party Claim at any time without the consent of the Indemnitor, provided that the terms and conditions of such settlement
involve solely the payment of money damages and the Indemnified Party waives any right to indemnification therefor by the Indemnitor. 
  
 (iv) If the potential Indemnitor does not provide the notice described in Section 8.7(a)(ii) within the 30-day period required
thereby or if the potential Indemnitor fails to either contest or undertake settlement negotiations in connection with the Third Party Claim, the Indemnified Party shall thereafter have the right to contest, settle or reach a compromise with respect
to the Third Party Claim at its exclusive discretion, at the risk and expense of the Indemnitor, and the Indemnitor will thereby waive any claim, defense or argument that the Indemnified Party’s settlement or defense of such Third Party Claim
is in any respect inadequate or unreasonable. Notwithstanding the foregoing, if the potential Indemnitor fails to provide the notice described in Section 8.7(a)(ii) within the 30-day period required thereby, the potential Indemnified
Party shall 

  

 16 

 
provide one fax notice of such Third Party Claim to the chief legal officer of the potential Indemnitor. If the Potential Indemnitor still does not provide
the required notice within three days after receipt of such fax notice, the potential Indemnitor shall not be deemed by such failure to have accepted liability for the Third Party Claim except to the extent that the Indemnified Party is materially
prejudiced by the failure to provide notice within the 30-day period. 
  
 (b) Non Third Party Claims. 
  
 (i) Each Party shall deliver to the other Party or parties against whom a claim for indemnification is to be made under this Section 8 written notice of any claims for indemnification under this
Section 8, other than Third Party Claims, which notice shall include a statement of the basis of the claim for indemnification, including a summary of the facts or circumstances that form the basis for the claim, and a good faith
estimate of the actual or future potential amount of Losses. 
  
 (ii) A potential Indemnitor shall have 30 days after its receipt of the claim notice to notify the potential Indemnified Party in writing whether or not the potential Indemnitor agrees that the claim is subject to
this Section 8 (a “Response Notice”). If the potential Indemnitor does not provide a Response Notice to the Indemnified Party within the required 30-day period, the Indemnitor shall be deemed to accept liability for all
Losses described in the claim notice. Notwithstanding the foregoing, if the potential Indemnitor fails to provide a Response Notice within such 30-day time period the potential Indemnified Party shall provide one fax notice of such claim to an
officer of the potential Indemnitor. If the potential Indemnitor does provide a Response Notice within three days after receipt of such fax notice, the potential Indemnitor shall not be deemed by such failure to have accepted liability for the claim
except to the extent that the Indemnified Party is materially prejudiced by the failure to provide such notice within the 30-day period. 
  
 (c) Exclusive Remedy. A Party’s right to indemnification provided in this Section 8 is the
sole and exclusive remedy of that Party from and after the Closing with respect to any Losses arising out of or relating to the negotiation, execution, delivery, performance or non-performance of this Agreement or the transactions contemplated
hereby; provided, however, that nothing in this Section 8.8 shall restrict or prohibit any Party from bringing any action (i) for injunctive relief or specific performance to the extent legally available or (ii) in the
event of fraud by a Party. Each Party waives any provision of applicable Law to the extent it would initiate, limit or restrict the agreement in this Section 8.8. 
  
 SECTION 9. MISCELLANEOUS 
  
 9.1 Costs and Expenses. Unless otherwise expressly provided in this Agreement, each Party shall pay be responsible for

provided in this Agreement, no waiver of any of the provisions of this Agreement shall be deemed, or shall constitute, a waiver of any other provision, whether or not similar, nor shall any waiver constitute a continuing waiver, and no waiver shall
be binding on any Party unless evidenced by an instrument in writing executed by the Party against whom the waiver is sought to be enforced.

the other, such consent not to be unreasonably withheld or delayed. 
  
 9.6 Notices. All notices, consents, requests, instructions, approvals and other communications provided for herein shall be validly given, made or served, if in writing and delivered personally or by
