(c)The following provisions shall govern the rights and obligations of the Parties to extend any of the dates for the Distribution Company TSA Critical Milestones not yet achieved under the Distribution Company TSA and the Critical Milestones not yet achieved under this Agreement:

(i)Purchaser may elect to require Owner to extend all of the dates for the Distribution Company TSA Critical Milestones not yet achieved under the Distribution Company TSA by up to four (4) six-month periods for a maximum combined period of two (2) years from the applicable dates set forth in Section 4.1(a) thereof by delivering Credit Support to Owner for the benefit of

Distribution Company (in addition to the Twenty-One Million, Eight Hundred Thousand Dollars ($21,800,000) of security delivered to Distribution Company and the other RFP Sponsors by Purchaser pursuant to the PPA and the Additional PPAs) in an amount equal to $5,000 per MW of PPA Contract Maximum Amount for each such six-month period, with a pro rata adjustment of the amount of any such additional Credit Support for any partial reduction of the applicable six-month period pursuant to Section 4.1(e). Any such election shall be made in a written notice to Owner on or prior to the first date for a Distribution Company TSA Critical Milestone that has not yet been achieved (as such date may have previously been extended). Such additional Credit Support shall be provided by Purchaser if there is a Purchaser Delay and Purchaser wishes to extend any Distribution Company TSA Critical Milestone date. In the event that there is both an Owner Delay and a Purchaser Delay and either Party wishes to extend any Distribution Company TSA Critical Milestone date by delivering additional Credit Support to Distribution Company, the additional Credit Support shall be provided in equal parts by Owner and Purchaser. Owner shall cause any additional Credit Support provided by Purchaser pursuant to this Section 4.1(c) to be returned to Purchaser upon the Commercial Operation Date; provided that, in the event the Commercial Operation Date is not achieved by the Target Date, Distribution Company shall have the rights and remedies set forth in Article XIV of the Distribution Company TSA, which, for the avoidance of doubt, shall include recourse against any Credit Support provided to Distribution Company.

(ii)Owner may elect to extend all of the dates for the Distribution Company TSA Critical Milestones not yet achieved under the Distribution Company TSA in accordance with Section 4.1(c) of the Distribution Company TSA.

In the event that there is both an Owner Delay and a Purchaser Delay and either Party wishes to extend any Distribution Company TSA Critical Milestone date by delivering additional Credit Support to Distribution Company, the additional Credit Support shall be provided in equal parts by Owner and Purchaser.

(iii)Upon any extension of any of the dates for the Distribution Company TSA Critical Milestones not yet achieved under the Distribution Company TSA, the corresponding dates for the Critical Milestones not yet achieved hereunder shall be extended accordingly; provided that Owner shall not agree to any extension of the Distribution Company TSA Critical Milestones beyond what is permitted under the Distribution Company TSA or this Agreement without the prior written consent of Purchaser, such consent not to be unreasonably withheld, conditioned or delayed.

(d)To the extent a Force Majeure event pursuant to Section 15.1 has occurred that prevents Owner or Purchaser from achieving the Critical Milestone dates for execution of the contract to purchase the converter station for the NECEC Transmission Line (Section 4.1(a)(v)), execution of the contract to purchase the converter station for the

Québec Line (Section 4.1(a)(vi)) or the Commercial Operation Date (Section 4.1(a)(vii)) by the applicable Critical Milestone date, the Critical Milestone date(s) impacted by such Force Majeure event shall be extended for the duration of the Force Majeure event, but under no circumstances shall extensions of those Critical Milestone dates exceed twelve (12) months beyond the applicable Critical Milestone date provided that (i) Owner shall not have the right to declare a Force Majeure event related to the Critical Milestone for Owner Approvals (Section 4.1(a)(i)), Municipal Owner Approvals (Section 4.1(a)(iii)), or the financing Critical Milestones (Section 4.1(a)(iv)); and (ii) Purchaser shall not have the right to declare a Force Majeure event related to the Critical Milestone for Canadian Approvals (Section 4.1(a)(ii)).

(e)In the event of a Regulatory Approval Delay, the date for each Critical Milestone not yet achieved shall be extended for the duration of the delay. The number of days of extension pursuant to the six-month extensions available under Section 4.1(c) shall be reduced by one day for each day of Regulatory Approval Delay pursuant to this subsection (e) up to a maximum reduction of 365 days. For purposes of illustration, Regulatory Approval Delay of two hundred ten (210) days would allow the Parties two six-month extensions and one extension of five months.

Section 4.2Commercial Operation Date.

(a)The “Target Date” for Commercial Operation is December 13, 2022 (as the same may be extended in accordance with Section 4.1(c), 4.1(d) or 4.1(e)) or such later date to which the Parties shall mutually agree in writing. Absent written agreement by the Parties, the Target Date may not be extended beyond December 13, 2024 unless such extension is due to Regulatory Approval Delay or an event of Force Majeure as set forth in Sections 4.1(d) and 4.1(e). The provisions of Sections 4.1(c), 4.1(d) and 4.1(e) and all other provisions of this Agreement are subordinate to this Section 4.2(a) and the aforesaid Section 4.1 provisions and such other provisions shall be construed in a manner that is consistent with this Section 4.2(a).

Such payments shall be made on a monthly basis pursuant to invoices delivered by Owner to Purchaser.

(ii)Québec Line Capacity is Lower. If, on the earlier of the Concurrent Remediation Date and the end of the Remediation Period, the operating capacity of the NECEC Transmission Line and the Québec Line have been increased to at or above 1,075 MW but less than 1,090 MW (and Distribution Company has waived any deficiency in capacity of the Québec Line or the NECEC Transmission Line), and the actual capacity of the Québec Line is less than the actual capacity of the NECEC Transmission Line, then Purchaser shall be liable to Owner for the Québec Line Capacity Deficiency Payment. Upon the making of such payment, this Agreement shall continue in effect at the actual operating capacity of the Québec Line that was considered for the purpose of determining such payment, and the Contract Capacity shall be deemed modified accordingly.

(iii)NECEC Transmission Line Capacity is Lower. If, on the earlier of the Concurrent Remediation Date and the end of the Remediation Period, the operating capacity of the NECEC Transmission Line and the Québec Line have been increased to at or above 1,075 MW but less than 1,090 MW, and the actual capacity of the NECEC Transmission Line is less than the actual capacity of the Québec Line, then Owner shall be liable to Purchaser for an amount equal to the Proportionate Share of the difference between the actual capacity of the Québec Line and the actual capacity of the NECEC Transmission Line as of the earlier of the Concurrent Remediation Date or the end of the Remediation Period, divided by an amount equal to 1,090 MW minus the actual capacity of the NECEC Transmission Line, multiplied by fifty percent (50%) of all costs prudently incurred by TransÉnergie as of the earlier of the Concurrent Remediation Date or the end of the Remediation Period in connection with the development and construction of the Québec Line. Upon the making of such payment, this Agreement shall continue in effect at the actual operating capacity of the NECEC Transmission Line that was considered for the purpose of determining such payment, and the Contract Capacity shall be deemed modified accordingly.

(iv)Both Lines Have Capacity Shortfall.

Without limitation of any obligations Owner may have under Section 15.1 hereof, in the event of damage to or loss of all or part of the NECEC Transmission Line, Owner shall exercise prompt, diligent commercially reasonable efforts to effectuate, in accordance with Good Utility Practice, such repairs and replacements as are necessary or desirable to restore the NECEC Transmission Line to its operating condition immediately prior to such damage or loss, including, for the avoidance of doubt, the application to such repairs or replacements of any potential or actual proceeds realized in connection with such damage or loss under any available or applicable

insurance policies (subject to insurance contract/policy terms and conditions of coverage) maintained pursuant to this Section 5.4. Subject to Owner’s compliance, in all material respects, with this Section 5.4, Section 6.3 and all other material terms and conditions with respect to the operation and maintenance of the NECEC Transmission Line, in the event that the costs to restore the NECEC Transmission Line to its operating condition immediately prior to such damage or loss exceed the available insurance proceeds by more than the greater of (a) an amount equal to three percent (3%) of the Net Book Value of the NECEC Transmission Line and (b) Thirty Million Dollars ($30,000,000), the Parties will negotiate in good faith an appropriate allocation of financial responsibility for such excess costs. In the event that the Parties do not agree on the allocation of financial responsibility, Purchaser shall be entitled to terminate this Agreement, upon thirty (30) days’ written notice to Owner, without liability to Owner; provided that, if within the thirty (30) day period following receipt of such notice, Owner agrees to assume that portion of the allocation of financial responsibility to which Purchaser objected, then the termination notice shall be deemed revoked and this Agreement shall not be terminated.

Section 5.5Compliance with Laws. At all times during the Term, the Parties shall comply with all Applicable Laws (including ISO-NE Rules to the extent applicable) and relevant Governmental Approvals and Third Party Consents.

Section 5.6Third Party Contracts. At all times during the Term, Owner shall, in a commercially reasonable manner, (a) satisfy its obligations under all third-party contracts entered into in connection with the NECEC Transmission Line, the AC Upgrades or CCIS Capacity Upgrades, and (b) administer all third-party contracts entered into in connection with the NECEC Transmission Line, the AC Upgrades or CCIS Capacity Upgrades.

Neither Purchaser nor its Affiliates shall be entitled to recover from Owner any losses, damages, costs or expenses related to the Québec Line or arising under the TransÉnergie OATT, except to the extent included in (a) an Owner Termination Payment, or (b) any damages paid pursuant to Section 4.4.1(a), Section 4.4.1(c), or Section 4.4.3.

Section 5.8Continuity of Rights and Responsibilities. Unless otherwise agreed in writing by the Parties or prohibited by Applicable Law, the Parties shall continue to provide service and honor commitments under this Agreement and continue to make payments in accordance with this Agreement pending resolution of any bona fide Dispute hereunder or relating hereto.

Section 5.9Right of First Offer to Purchase NECEC Transmission Line.

(a)Subject to the receipt of any required regulatory approvals and Third Party Consents, prior to conducting any Marketing Activities, Owner shall provide Purchaser with the right to offer to buy, directly or through an Affiliate, the NECEC Transmission Line in accordance with this Section 5.9, by providing Purchaser with written notice of Owner’s intent to sell the NECEC Transmission Line (to the extent that such sale relates only to the NECEC Transmission Line without any other material assets) (such notice, a “Marketing Notice”). Upon receipt of the Marketing Notice, Purchaser shall then have forty five (45) days to make an offer to purchase the NECEC Transmission Line, which offer shall contain reasonably detailed information relating to the price (such

price, the “Offer Price”) and all material economic terms of the transaction upon which Purchaser is willing to purchase the NECEC Transmission Line. If Purchaser elects to make such an offer, Owner shall, within thirty (30) days following the receipt of such offer, either (i) accept such offer, in which case the parties will proceed to close the purchase of the NECEC Transmission Line within the next sixty (60) days (or such longer period as is reasonably necessary to obtain all required approvals and consents) on the terms contained in such offer, or (ii) reject such offer.

(b)If Owner rejects the offer made by Purchaser, then Owner shall be free to thereafter sell the NECEC Transmission Line to third parties (subject to the provisions of this Agreement) within the twelve (12) months following the date of Owner’s rejection of Purchaser’s offer for a price higher than one hundred percent (100%) of the Offer Price, with economic terms not materially less favorable to Owner (taken in the aggregate) than those contained in Purchaser’s offer (or, if materially less favorable, then with such adjustments to the price to account for any such material differences in the economic terms of the sale).

Section 5.10Amendment to the PPA. Purchaser shall not amend or otherwise modify the PPA, or seek or provide any waiver of any term or condition of the PPA, in a manner that adversely and materially affects Purchaser’s rights under this Agreement or that would result in an increase in Owner’s liability pursuant to clause (b) of “Owner Termination Payment,” clause (b)(ii) of “Owner Termination Payment” (as defined in the Distribution Company TSA) or Section 3.3.3 or that would affect Owner’s rights under Section 7.2(b) without the consent of Owner, which consent shall not be unreasonably withheld, conditioned or delayed. Purchaser shall provide Owner with notice of any amendment or other modification to Section 8.3 of the PPA prior to the effective date of such amendment.

Section 5.11Amendment to the Distribution Company TSA. Owner shall not (a) terminate the Distribution Company TSA pursuant to Section 3.3.2 thereof or (b) agree to any amendment or other modification of the Distribution Company TSA, or seek or provide any waiver of any term or condition of the Distribution Company TSA, that adversely and materially affects Purchaser’s rights under this Agreement (including in a manner that would result in an increase in the credit support provided by Owner under the Distribution Company TSA), in each case without the consent of Purchaser, which consent shall not be unreasonably withheld, conditioned or delayed.

Article VI

PROCEDURES FOR OPERATION AND MAINTENANCE
OF THE NECEC TRANSMISSION LINE

Section 6.1Transmission Operating Agreement; ISO-NE Operational Control.

(a)Prior to entering into the Transmission Operating Agreement, Owner shall consult Purchaser with respect to the proposed terms and conditions thereof and Owner shall make a good faith effort to take into account any comments made by Purchaser. Purchaser shall promptly provide comments, if any, to Owner on such terms and conditions.

(b)As of the Commercial Operation Date, Owner shall transfer operational control over the NECEC Transmission Line, as defined in the Transmission Operating Agreement, to Transmission Operator in accordance with the Transmission Operating Agreement. Owner shall provide, and shall direct its Affiliates to provide, such information as Transmission Operator may require to discharge its obligations under the Transmission Operating Agreement, and Owner shall comply with the instructions of Transmission Operator to the extent provided in the Transmission Operating Agreement and the ISO-NE Tariff. The Parties acknowledge and agree that Owner shall not be in breach of, or be liable to Purchaser under, this Agreement, and no Owner Default shall occur, as a consequence of Owner’s compliance with such instructions of Transmission Operator; provided that Owner did not initiate or support instructions that would otherwise breach Owner’s obligations under this Agreement.

Section 6.2Good Utility Practice; Regulatory and Reliability Requirements. From and after the Commercial Operation Date, Owner shall (a) provide Firm Transmission Service, (b) operate and maintain the NECEC Transmission Line in accordance with Good Utility Practice and in compliance with all applicable regulatory requirements, including applicable NERC and Northeast Power Coordinating Council reliability standards, and (c) comply with all applicable operating instructions of ISO-NE and manufacturers’ warranties.

Section 6.3Scheduled Maintenance. With respect to each calendar year (or portion thereof) following the Construction Phase, Owner will prepare and deliver to Purchaser a Maintenance Plan not later than the Commercial Operation Date and two (2) months prior to the end of each calendar year thereafter, and shall be available for consultation with Purchaser with respect thereto (including for coordination of maintenance schedules). Consistent with Good Utility Practice, Owner shall use commercially reasonable efforts to coordinate with TransÉnergie with respect to scheduled maintenance so as to minimize outages, including by meeting annually (or as otherwise necessary in order to comply with any applicable ISO-NE or Canadian regulatory or system operator requirements) to develop a Maintenance Plan. From and after the Commercial Operation Date, Owner shall coordinate all planned maintenance with ISO-NE, consistent with ISO-NE Rules, and shall promptly provide applicable information concerning scheduled outages, as determined by ISO-NE, to Purchaser. To maximize value, to the extent possible and consistent with ISO-NE Rules, Owner shall not schedule maintenance of the NECEC Transmission Line during the months of December, January and February or June through September and shall operate the NECEC Transmission Line so as to maximize energy production during the hours of anticipated peak load and energy prices in New England; provided, however, that planned maintenance may be scheduled during such period to the extent the failure to perform such planned maintenance is contrary to operation of the NECEC Transmission Line in accordance with Good Utility Practice. Owner may modify a Maintenance Plan in accordance with Good Utility Practice; provided, however, that (a) a Maintenance Plan may not be modified for the purpose of reducing the magnitude or duration of a Non-Excused Outage, (b) any modification shall, to the extent commercially reasonable, maximize value in the manner described in this Section 6.3 and (c) Owner shall provide Purchaser with reasonable notice of any change in a Maintenance Plan. Any maintenance that is not included in the Maintenance Plan for a year and is not otherwise excused under Section 7.2 shall be a Non-Excused Outage.

Article VII

PURCHASER’S TRANSMISSION RIGHTS OVER THE
NECEC TRANSMISSION LINE

Section 7.1Transmission Service.

Section 7.1.1 Firm Transmission Service. Owner shall make available to Purchaser throughout the Purchaser Term transmission capacity on the NECEC Transmission Line in order to deliver electrical energy, as scheduled by Purchaser or its designee or assignee under the resale provisions of Article X, in such scheduled amount up to the Contract Capacity, measured at the Delivery Point (“Firm Transmission Service”). Firm Transmission Service shall be made available over the NECEC Transmission Line during the Purchaser Term, in a north-to-south direction, and to the extent available in a south-to-north direction, between the U.S. Border and the Delivery Point. Firm Transmission Service shall be subject to curtailment or interruption only as a result of an Excused Outage or as provided in Section 14.4(b). Without limiting Owner’s obligations under this Section 7.1.1, the quantity of Firm Transmission Service that Owner will provide in any hour shall not exceed the Proportionate Share of the Available Transfer Capability for such hour.

Section 7.1.2 Limitation on Transmission Service. Owner shall have no obligation to provide transmission service under this Agreement other than Firm Transmission Service. Purchaser shall have no right to redirect service to alternate points of delivery or receipt on any portion of the transmission system operated by ISO-NE other than the NECEC Transmission Line.

Section 7.1.3 Scheduling. All Firm Transmission Service shall be scheduled in accordance with the rules relating to the scheduling of electrical energy or capacity transactions over the NECEC Transmission Line, as established under the Transmission Operating Agreement (the “Scheduling Rules”).

Section 7.1.4 Owner’s Cooperation. Owner shall provide Purchaser with notice of any FERC or NERC regulatory proceedings relating to the NECEC Transmission Line or this Agreement to which Owner is a party promptly after Owner becomes aware of any such proceedings. Each Party will act in good faith regarding any such proceedings. Neither Party shall take any position in such proceeding that is contrary to such Party’s obligations under this Agreement.

Section 7.2Excused Outages or Reductions.

(a)Notwithstanding anything herein to the contrary, Owner shall not be in breach of, or be liable to Purchaser for any losses or damages under, this Agreement, and no Owner Default shall occur, as a consequence of an Excused Outage. “Excused Outages” means any outages of the NECEC Transmission Line or reductions in the Total Transfer Capability below the NECEC Transmission Line Capacity, whether as a result of a physical condition, legal impediment or otherwise, if and to the extent such outage or reduction is due to:

(i)Events of Force Majeure;

(ii)Scheduled maintenance in accordance with the applicable Maintenance Plan;

(iii)Outages or reductions in the availability of the Québec Line for any reason; or

(iv)Decisions of ISO-NE or any other independent system operator to reduce or suspend scheduling rights over the NECEC Transmission Line or the Québec Line, including as a result of any grid reliability issue, emergency condition as defined in any Interconnection Agreement or the ISO-NE Tariff, or to preserve facilities and equipment from physical damage and including any such decisions that arise from outages or reductions in the use or availability of transmission lines other than the NECEC Transmission Line or the Québec Line, which outage or reduction arises from or is attributable to Force Majeure or scheduled maintenance.

(b)Notwithstanding anything in Section 7.3.1 to the contrary, Purchaser shall remain obligated, during and to the extent of any Excused Outage, to pay the Transmission Service Payment without downward adjustment to reflect any such outage, reduction or delay. Owner shall seek to avoid and mitigate or remedy any Excused Outage consistent with Good Utility Practice.

(c)Notwithstanding anything herein to the contrary and without regard to whether an Excused Outage is due to Force Majeure, if an Excused Outage prevents Owner’s full or partial performance under this Agreement during the Purchaser Term for a period of twelve (12) consecutive months or more, Purchaser shall have the right, as provided in Section 15.1(c) herein, to terminate this Agreement upon written notice to Owner and without further recourse.

Section 7.3Non-Excused Outages or Reductions.

Section 7.3.1 Reduction in Transmission Service Payments. In the event the average Hourly Availability of the NECEC Transmission Line over any calendar month following the Commercial Operation Date due to a Non-Excused Outage is less than the Minimum Average Availability for such calendar month (whether as a result of a physical condition, legal impediment or otherwise), unless otherwise excused under Section 7.2 or Section 11.1, and as a result thereof Owner is unable (in whole or in part) to provide the full Contract Capacity of Firm Transmission Service contemplated by Section 7.1.1 during the Term or firm transmission service contemplated by Section 7.1.1 of the Distribution Company TSA during the term of the Distribution Company TSA, Purchaser shall have the right to recover from Owner, and Owner shall pay to Purchaser, for each such month during which a Non-Excused Outage occurs, the Non-Excused Outage Payment; provided that, in no event, shall the total amount of (a) all Non-Excused Outage Payments made in any Contract Year under this Agreement plus (b) all Non-Excused Outage Payments (as defined in the Purchaser TSAs) made in any Contract Year plus (c) all Non-Excused Outage Payments (as defined in the 110 MW TSA) made in any Contract Year exceed Twenty Million Dollars ($20,000,000); provided further that such cap shall be proportionately reduced in any Contract Year that is less than a full calendar year. Any Dispute

over whether or not or to what extent a Non-Excused Outage has occurred shall be resolved in accordance with Article XVII. Such amounts shall be payable on a monthly basis pursuant to invoices delivered by Purchaser to Owner. Owner shall seek to avoid, mitigate and remedy any Non-Excused Outage consistent with Good Utility Practice.

Section 7.3.2 [Intentionally Omitted].

Section 7.3.3 Liquidated Damages. The Parties acknowledge and agree that the payment of amounts by Owner to Purchaser under Section 7.3.1 and the modification of Purchaser’s payment obligations pursuant to Section 8.1 are an appropriate remedy and that any such payment or modification does not constitute a forfeiture or penalty of any kind. The Parties further acknowledge and agree that the damages for a Non-Excused Outage are difficult or impossible to determine and that the damages calculated hereunder constitute a reasonable approximation of the harm or loss to Purchaser as a result thereof.

Section 7.3.4 Sole and Exclusive Remedy. The rights provided in Section 3.3.5, this Section 7.3 and Section 8.1 shall collectively be the sole and exclusive remedies of Purchaser with respect to a Non-Excused Outage, subject to (a) Purchaser’s right to recover any costs or expenses (including reasonable attorneys’ fees) reasonably incurred by Purchaser to recover any amounts owed to Purchaser by Owner under this Agreement, (b) Purchaser’s right to recover payment of any indemnification obligations of Owner to Purchaser pursuant to Section 20.1, (c) Purchaser’s rights upon the occurrence of an Owner Default as described in Section 14.3 or (d) Purchaser’s rights in the event of Real Power Losses pursuant to Section 11.1.

Section 7.4Allocation of Outages.

Purchaser’s transmission service under the 110 MW TSA shall be reduced before any reductions are applied to Distribution Company’s transmission service under the Distribution Company TSA or the Additional RFP Sponsor TSAs.

Section 7.5Metering. Metering and telemetering requirements for the NECEC Transmission Line shall be established by Owner in accordance with Good Utility Practice and as necessary to (a) accomplish the purposes of, and to implement and administer, this Agreement and (b) satisfy the requirements of, and to implement and administer, the PPA, the Interconnection Agreement and the Transmission Operating Agreement.

Section 7.6Line Availability Information and Reporting. Owner shall make available to Purchaser on a real time basis information relating to the operation and availability of the NECEC Transmission Line and shall provide such additional information as Purchaser shall reasonably request.

Article VIII

PAYMENTS FOR TRANSMISSION SERVICE OVER THE
NECEC TRANSMISSION LINE

Section 8.1Transmission Service Payments. During the period beginning on the twentieth (20th) anniversary of the Commercial Operation Date and ending on the fortieth (40th) anniversary of the Commercial Operation Date (unless earlier terminated) (the “Purchaser Term”), except to the extent such payment is excused or reduced pursuant to the terms of this Agreement, Purchaser shall pay to Owner a transmission service payment (the “Transmission Service Payment”) on a monthly basis pursuant to invoices delivered by Owner to Purchaser equal to Seven Dollars Thirty Eight Cents ($7.38) per KW of Contract Capacity per month. The Transmission Service Payment shall be reduced in accordance with the formula set forth in Attachment G in the event and to the extent that the average Hourly Availability of the NECEC Transmission Line over any calendar month following the Commercial Operation Date due to a Non-Excused Outage is less than the Minimum Average Availability for such calendar month (whether as a result of a physical condition, legal impediment or otherwise), unless otherwise excused under Section 7.2, and as a result thereof Owner is unable (in whole or in part) to provide the full Contract Capacity of Firm Transmission Service contemplated by Section 7.1.1. To the extent there is a Dispute over whether or not or to what extent a Non-Excused Outage has occurred, Purchaser’s right, pursuant to this Section 8.1, to any reduction in the Transmission Service Payment shall be implemented upon the resolution of such Dispute and such reduction will be effective as of the date when such Dispute arose. Such adjustments shall be made on a monthly basis pursuant to invoices delivered by Owner to Purchaser.

Section 8.2Adjustment to Rate Upon Purchaser Step-in. Notwithstanding anything in the Distribution Company TSA to the contrary, in the event Purchaser elects to assume the rights and obligations of Distribution Company under the Distribution Company TSA, as provided in Section 14.8(a) or 14.8(b), the transmission service payment payable under the Distribution Company TSA by Purchaser for the remainder of the term thereunder shall be equal to that portion of the transmission service payment payable under the Distribution Company TSA comprising Owner’s non-capital expenses related to the NECEC Transmission Line, and Purchaser shall not be required to compensate Owner for any depreciation, equity return or cost of capital during the remainder of the term under the Distribution Company TSA. In the event of such assumption and upon request of Purchaser, the Parties shall amend the Distribution Company TSA to give effect to this Section 8.2.

Section 8.3Elective Upgrade Status; No Regional Rates. It is the intent of the Parties that the NECEC Transmission Line has Elective Transmission Upgrade status during the Term and that the AC Upgrades and the CCIS Capacity Upgrades constitute Network Upgrades under the ISO-NE Tariff required to accommodate the interconnection of the NECEC Transmission Line. The Parties acknowledge and agree that (a) as contemplated by the PPA, Purchaser shall participate in such Forward Capacity Auction (as defined in the ISO-NE Rules) qualification process as required to allow Purchaser to qualify a Seasonal Claimed Capability (as defined in the ISO-NE Rules) of not less than 1,200 MW over the NECEC Transmission Line no later than the Guaranteed Delivery Term Start Date (as defined in the PPA), as it may be extended pursuant to Sections 3.1(c) through 3.1(f) of the PPA and (b) such Network Upgrades, if any, shall be at

Owner’s sole expense. It is the further intent of the Parties that Owner’s recovery of the investment in and return on the NECEC Facilities and Purchaser’s obligation to pay for the NECEC Facilities, shall be solely governed by this Agreement. The Parties each shall refrain from taking steps to include all or part of the NECEC Facilities in ISO-NE regional transmission rates during the Term. Notwithstanding the foregoing, if during the Term all or part of the NECEC Facilities are included in ISO-NE regional rates paid by Purchaser, the payment required by Section 8.1 shall be reduced by the Proportionate Share of the revenues received by Owner from such ISO-NE rates with respect to the NECEC Facilities. “NECEC Facilities” means the NECEC Transmission Line, the AC Upgrades, and the CCIS Capacity Upgrades.

Article IX

RIGHTS UPON EXPIRATION OF TERM

Section 9.1Rollover Rights.

(a)Unless this Agreement is terminated early under Section 3.3, Section 14.4 or Section 14.6, Purchaser shall have rollover rights at the end of the Purchaser Term in accordance with FERC Order No. 890 et seq. and the FERC pro forma open access transmission service tariff, as such rights are defined as of the Effective Date.

(b)Owner shall not enter into any contract or other arrangement for use of the NECEC Transmission Line that is inconsistent with Purchaser’s rollover rights, as provided herein.

Article X

RESALE OF TRANSMISSION SERVICE

Section 10.1Resale Rights of Purchaser. If and to the extent Purchaser (including, prior to the Purchaser Term, in its capacity as assignee of transmission rights under Section 20 of the PPA) determines from time to time, and in its sole discretion, that the transmission capacity available to Purchaser relevant to the receipt of Firm Transmission Service over the NECEC Transmission Line pursuant to this Agreement exceeds Purchaser’s needs, Purchaser shall then offer to resell such unused capacity to third parties in accordance with Applicable Law as may then be in effect (including the terms and conditions of FERC Order No. 890 et seq., if applicable).

Section 10.2Capacity Releases for Daily and Hourly Use. From and after the Commercial Operation Date, if and to the extent the Proportionate Share of the Available Transfer Capability exceeds the amount of electrical energy that is scheduled by Purchaser for delivery over the NECEC Transmission Line using Firm Transmission Service by the applicable scheduling deadline (as in effect at such time) established pursuant to the Scheduling Rules, then the transmission capacity that is available for resale to third parties for the following day, and the price at which any such resales are offered, shall be posted on the OASIS site established pursuant to Section 10.3.

Section 10.3OASIS.

(a)Owner or an Affiliate of Owner (in such capacity, the “OASIS Administrator”) shall establish an OASIS site for the NECEC Transmission Line and administer such site in accordance with applicable FERC requirements for the establishment and administration of OASIS sites. None of Owner, the OASIS Administrator or Purchaser shall be liable to each other or any third party for any decisions the OASIS Administrator makes regarding the appropriate price for resales of unused transmission capacity or the level of any such resales the OASIS Administrator is able to make. The Parties agree that there shall be no damages as between each other or third parties for actions by the OASIS Administrator with respect to resales of unused transmission capacity.

(b)To the extent resales are made available by Purchaser pursuant to Section 10.1, the OASIS Administrator shall post on the OASIS site information regarding such resales, (i) in accordance with written instructions provided by Purchaser from time to time and (ii) at a price established by Purchaser from time to time, and in its sole discretion, as permitted under Applicable Law.

Section 10.4Proceeds from Capacity Releases and Transmission Resales. Except as otherwise provided in Section 14.4(b), Purchaser’s proceeds received by Owner of any capacity releases and transmission resales that are made during the Purchaser Term pursuant to this Article X shall be credited, net of reasonable fees (including attorneys’ fees) and other expenses incurred in connection with performance of the functions described in Section 10.2 and Section 10.3, against any Transmission Service Payment or other amounts owed to Owner by Purchaser for the calendar month subsequent to the calendar month in which such proceeds were received.

Section 10.5Owner’s Rights and Obligations. Except as expressly provided in the Proposal Agreements, Owner shall have no right or obligation to offer any transmission service over the NECEC Transmission Line for sale or resale to any Person other than Purchaser, as provided herein.

Article XI

REAL POWER LOSSES, CONGESTION AND CAPACITY RIGHTS

Section 11.1Real Power Losses. Purchaser shall be responsible for all Real Power Losses associated with Firm Transmission Service; provided, however, that, if and to the extent any Real Power Losses associated with Firm Transmission Service between the U.S. Border and the Delivery Point are due to Owner’s failure to exercise Good Utility Practice or otherwise discharge its obligations under this Agreement, (a) such incremental Real Power Losses shall be treated as Non-Excused Outages for which Owner shall be liable in accordance with Section 7.3 and (b) the Transmission Service Payments owed by Purchaser shall be reduced pursuant to Section 8.1; and provided, further, that during the Term Owner shall (x) exercise diligent, commercially reasonable efforts to maximize the warranty or similar obligations of its vendors and suppliers for the NECEC Transmission Line with respect to such Real Power Losses under any Construction Contract or otherwise and (y) credit, assign or pay over to Purchaser any amounts receivable by or paid to Owner under such warranties or similar obligations, including

liquidated damages under any Construction Contract, related to such Real Power Losses, and the rights and remedies contemplated by Section 3.3.5, Section 7.3, Section 8.1 and this Section 11.1, shall collectively be the sole and exclusive remedy of Purchaser with respect to any such incremental Real Power Losses.

Section 11.2Other Rights.

(a)Purchaser shall be entitled during the Purchaser Term to its Transmission Percentage of the following, without duplication and without additional cost to Purchaser or compensation to Owner: (i) all Other Transmission Rights associated with the NECEC Transmission Line or the AC Upgrades, in each case, that are issued in accordance with the ISO-NE Tariff or otherwise granted under the ISO-NE Rules, or otherwise created or awarded by ISO-NE and (ii) all other Market Products that are issued in accordance with the ISO-NE Tariff or granted under the ISO-NE Rules, or otherwise created or awarded by ISO-NE, that derive from the acquisition of transmission service over the NECEC Transmission Line. As Owner’s sole obligation under this clause (a), upon its receipt of any of the entitlements or rights described in the foregoing sentence, Owner shall promptly convey such entitlements or rights to Purchaser.

(b)In the event tie benefits or interconnection capability credits (or any similar concept) are ever deemed applicable to the NECEC Transmission Line and to the extent allocated to any Party during the Purchaser Term, Purchaser shall be entitled to its Transmission Percentage of one hundred percent (100%) of the economic benefits associated therewith (however entitled and whether existing now or in the future), without additional cost to Purchaser or compensation to Owner.

(c)Owner shall have no obligation to support the creation or establishment of any of the rights described in clauses (a)(ii) and (b) above, but Owner may not oppose the creation or establishment of any such right, unless otherwise agreed in writing by Purchaser. Neither Section 2.5 nor the foregoing sentence shall be construed in any way to limit the right of any Affiliate of Owner to oppose the creation or establishment of any of the rights described in clauses (a)(ii) and (b) above.

Article XII

[INTENTIONALLY OMITTED]

Article XIII

BILLING AND PAYMENTS

Section 13.1Invoices. Within seven (7) Business Days after the first day of each calendar month following the commencement of the Purchaser Term, Owner shall submit an Invoice to Purchaser for the Transmission Service Payments owed for the preceding calendar month, and Purchaser shall pay the amounts set forth in the Invoice to Owner within fourteen (14) Business Days following its receipt of such Invoice. All payments shall be made in immediately available funds payable to Owner by wire transfer to a bank named by Owner, in accordance with wiring instructions provided to Purchaser by Owner in writing. Owner shall be entitled to change the place or recipient for payment by thirty (30) days’ prior written notice to Purchaser.

Section 13.2Procedures for Billing Disputes.

(a)In the event of any Dispute with respect to the amount owed to Owner by Purchaser under this Agreement, Purchaser shall have no right to withhold payment of the Disputed amount pending resolution of the Dispute; provided, however, that, in the event such Dispute is resolved in favor of Purchaser, Owner shall complete the following tasks consistent with the resolution of such Dispute: (i) retroactively adjust all payments previously made by Purchaser; (ii) promptly refund all overpayments previously made by Purchaser, together with interest thereon in immediately available funds or by wire transfer, in each case, in accordance with wiring instructions provided to Owner by Purchaser in writing; and (iii) thereafter conform all future Invoices to reflect the resolution of such Dispute, as applicable. Purchaser’s payment of any Disputed amounts shall be without prejudice to any right or remedy that Purchaser may have under this Agreement to contest any such amount.

(b)Purchaser shall not have the right to challenge any Invoice or to bring any action of any kind challenging the propriety of any Invoice after the second (2nd) anniversary of the receipt of such Invoice. If an Invoice is not rendered within two (2) years after the end of the calendar month during which such Invoice should have been rendered hereunder, then the right to payment of such Invoice is waived.

Section 13.3Interest. All interest payable under this Section 13.3 shall be calculated pursuant to 18 C.F.R. § 35.19a(a), as such regulation (or any successor thereto) is in effect during the period during which such interest is due. Amounts not paid when due to Owner or Purchaser under this Agreement shall bear interest from the date such amount was due until the date of payment of such overdue amount. For the avoidance of doubt, as illustrated in Attachment H, if all or a portion of the amount to which such interest relates is later refunded pursuant to this Agreement, then, in calculating that refund, such interest shall not be included in the refund. Refunds of overpayments owed to Purchaser by Owner under this Agreement shall begin to accrue interest on the amount subject to refund, as originally invoiced, from the earlier to occur of the due date or the date of payment of the monthly Invoices to which the overpayment relates and shall continue to accrue interest until the date of payment of such refund.

Section 13.4Obligation to Make Payments. The Parties acknowledge and agree that, except as set forth in Section 8.1, Section 13.5 and Section 14.6(d), no cause or event whatsoever shall excuse or suspend Purchaser’s obligation to pay Transmission Service Payments or any other amounts payable by Purchaser under this Agreement. The Parties also acknowledge and agree that no cause or event whatsoever shall excuse or suspend any amounts payable by Owner under this Agreement.

Section 13.5Offsets. Except as otherwise provided in Section 3.4(a) and Section 14.6(d), neither Party shall be entitled to deduct or set-off payment of any amount owed to the other Party under this Agreement against payment of any amount owing under this Agreement. The Parties shall have the right to deduct or set-off payments of amounts owed hereunder against payments of amounts owing under the 110 MW TSA or the Purchaser TSAs.

Article XIV

EVENTS OF DEFAULT AND REMEDIES

Section 14.1Purchaser Defaults. Except to the extent excused as a result of an event of Force Majeure in accordance with Article XV, the occurrence of one or more of the following events shall constitute a default by Purchaser under this Agreement (a “Purchaser Default”); provided that an event of Force Majeure shall not excuse an event described in clause (a), clause (e), clause (f) or clause (g):

(a)Purchaser’s failure to pay any undisputed amount due to Owner under this Agreement by the due date, which failure is not cured within ten (10) days after the receipt by Purchaser of a written demand from Owner that such amount is due and owing and has not been timely paid.

Section 14.7Purchaser Step-in Rights.

(a)In the event that (i) an Owner Default or an Owner Default (as defined in the Distribution Company TSA) occurs or (ii)(A) Owner exercises its rights pursuant to Section 14.2(e) of the Distribution Company TSA or Section 14.3(e) of this Agreement and (B) at the end of the first six (6) months of the period of forbearance by Purchaser of its rights as contemplated by Section 14.3(e) of this Agreement or Section 14.2(e) of the Distribution Company TSA, Owner is not providing Firm Transmission Service in full, then Purchaser shall have the right, but not the obligation, to (x) assume control of and possess and operate the NECEC Transmission Line as agent for Owner (in accordance with Owner’s rights, obligations and interest under this Agreement, the Distribution Company TSA and the Additional RFP Sponsor TSAs, as applicable) during the period provided for herein, pursuant to an agreement to be negotiated in good faith between Owner and Purchaser or (y) assume ownership, control of, possession and operation of the NECEC Transmission Line, in each case, which right shall be exercisable by written notice to Owner and subject to the receipt of any required regulatory approvals and Third Party Consents.

(b)Upon receipt of such written notice to assume ownership of the NECEC Transmission Line (the “Acquisition Notice”), Owner shall (i) provide such documents and information as is reasonably necessary for Purchaser to determine any amount owed pursuant to Section 14.7(c) and (ii) take all necessary action to effect the transfer of the NECEC Transmission Line to Purchaser (or its designated Affiliate), including causing all permits, title to land and property, and interests in all contracts (including Owner’s rights under this Agreement, the 110 MW TSA, the Purchaser TSAs, the Distribution Company TSA and the Additional RFP Sponsor TSAs, as applicable) applicable to the NECEC Transmission Line to be transferred to Purchaser or such designated Affiliate. Each Party shall, and each Party shall use commercially reasonable efforts to cause its Affiliates to, cooperate to obtain any required regulatory approvals and Third Party Consents necessary to effect the transfer of the NECEC Transmission Line to Purchaser.

(c)In consideration for acquiring the NECEC Transmission Line, on the closing date, as reasonably determined by Purchaser and specified in the Acquisition Notice, Purchaser shall pay to Owner an amount equal to (i) if such Owner Default occurs prior to the Commercial Operation Date, all costs prudently incurred by Owner as of the date of the Acquisition Notice in connection with the development and construction of the NECEC Transmission Line or (ii) if such Owner Default occurs on or after the Commercial Operation Date, the lesser of (A) one hundred percent (100%) of Owner’s investment in the NECEC Transmission Line as of the notice date and (B) the fair market value of the NECEC Transmission Line, as reasonably determined by a third party appraiser selected by Purchaser and reasonably acceptable to Owner (which amount shall be net of the costs of any such appraisal). The amount to be paid pursuant to this clause (c) shall be in satisfaction of any consideration required to be paid pursuant to Section 14.7 of all Purchaser TSAs and shall be determined within fifteen (15) days after the delivery of the Acquisition Notice or such other time period as is reasonably practicable.

(d)Upon receipt of all required regulatory approvals and Third Party Consents and the payment set forth in clause (c) above, Owner shall transfer to Purchaser (or its designated Affiliate), without recourse or warranty (except as to title and the absence of any liens other than liens arising in the ordinary course), all of Owner’s right, title and interest in and to the NECEC Transmission Line free and clear of all liens other than liens arising in the ordinary course and Purchaser (or such designated Affiliate) shall be assigned all rights of Owner under all contracts required for the ownership and operation of the NECEC Transmission Line and shall assume all liabilities and obligations of Owner arising under such contracts after the transfer (other than applicable contracts between Owner and its lenders, the liabilities and obligations of Owner thereunder to be completely satisfied and discharged by Owner as of closing) and Owner shall cease to be a Party.

(e)Upon Purchaser (or its designated Affiliate) assuming ownership and control of the NECEC Transmission Line:

(i)(A) Purchaser (or its designated Affiliate) shall have the right to terminate this Agreement and Purchaser may recover, as applicable, any accrued but unpaid amounts under Section 4.4.1, Section 4.4.3, or Section 7.3.1 or (B) Purchaser (or its designated Affiliate) shall assume Owner’s obligations under this Agreement pursuant to this Section 14.7 and Purchaser shall enter into such amendments to this Agreement as are reasonably necessary in order to give effect to such rights and that are consistent with the terms and conditions of this Agreement and are subject to applicable regulatory approvals;

(ii)Purchaser (or its designated Affiliate) shall assume the rights and obligations of Owner under the Distribution Company TSA, the Additional RFP Sponsor TSAs, the 110 MW TSA and the Purchaser TSAs for the remainder of the term thereof (excluding any rights and obligations accrued prior to such assumption).

(f)In connection with an event occurring that gives rise to Purchaser’s step-in rights pursuant to Section 14.7(a) (a “Step-In Trigger Event”) and the exercise by Purchaser of its rights under this Section 14.7, Owner shall pay liquidated damages to Purchaser (without duplication of any amounts paid under Section 14.7 of any other Purchaser TSA) in an amount equal to:

(i)if such Step-In Trigger Event occurs on or before December 31, 2019, Twelve Million Dollars ($12,000,000);

(ii)if such Step-In Trigger Event occurs after December 31, 2019, but on or before December 31, 2020, Thirty Million Dollars ($30,000,000);

(iii)if such Step-In Trigger Event occurs after December 31, 2020, but on or before December 31,2021, Seventy-Three Million Dollars ($73,000,000);

(iv)if such Step-In Trigger Event occurs after December 31, 2021 but before the Commercial Operation Date, Ninety Million Dollars ($90,000,000); or

(v)if such Step-In Trigger Event occurs on or after the Commercial Operation Date, One Hundred Million Dollars ($100,000,000).

The assumption by Purchaser (or its designated Affiliate) of ownership and control of the NECEC Transmission Line under this Section 14.7 shall constitute a waiver by Purchaser of all other remedies or damages that may be available at law or in equity against Owner; provided, however, that Purchaser shall not waive any right to, and Owner shall remain liable for, the liquidated damages set forth in this Section 14.7(f), any accrued but unpaid amounts under Section 4.4.1, Section 4.4.2, or Section 7.3.1 hereof or any express modification of Purchaser’s payment obligations that have accrued under this Agreement before or as of such termination, and any indemnification obligations of Owner to Purchaser under this Agreement, together with any costs or expenses (including reasonable attorneys’ fees) reasonably incurred by Purchaser to recover such damages or such indemnified or other amounts owed to Purchaser by Owner.

(g)Notwithstanding this Section 14.7, in the event that an Owner Default occurs and at any time prior to Purchaser (or its designated Affiliate) assuming ownership and control of the NECEC Transmission Line, (i) Purchaser may exercise its termination rights pursuant to Section 14.6(a) and the exercise of such termination rights shall result in a revocation of Purchaser’s step-in rights under Section 14.7(a) or (ii) Purchaser may revoke the exercise of its step-in rights under Section 14.7(a).

(h)Owner shall not grant any Person, other than a secured party in accordance with Section 22.3, a right to assume control of, possess and operate the NECEC Transmission Line that is equal to or superior to Purchaser’s right under this Section 14.7.

(i)As requested by Purchaser following its purchase of the NECEC Transmission Line pursuant to this Section 14.7, Owner agrees to grant to Purchaser (or its designated Affiliate) any such other rights of way, and assign to Purchaser or such designated Affiliate such other contracts to which it is then a party, as shall be necessary for the ownership, operation, and maintenance of the NECEC Transmission Line.

(j)Owner shall deliver true, correct and complete copies of all applicable contracts and books and records to Purchaser for its review no later than ten (10) days after receipt of the Acquisition Notice. Following the timely delivery by Owner to Purchaser of all such contracts and books and records, Purchaser shall be required to notify Owner at least twenty (20) days prior to the expected closing date if the terms and conditions of the assignment and assumption of any such contracts will not be satisfactory to Purchaser (or its designated Affiliate) and, if Purchaser does so notify Owner, such notice shall result in the revocation of the Acquisition Notice, and the Parties shall be deemed to be in the same position as if Purchaser had not delivered such Acquisition Notice. As a condition of closing, Owner shall completely satisfy and discharge its

liabilities and obligations under all applicable contracts between Owner and its lenders and Owner shall obtain written releases, in recordable form reasonably acceptable to Purchaser, of all liens (whether for the benefit of its lenders or otherwise) on the NECEC Transmission Line and the applicable contracts other than liens arising in the ordinary course, and Owner obligates itself to satisfy such liabilities and obligations and to obtain such releases as of closing.

Section 14.8Early Termination of Distribution Company TSA.

(a)Upon any termination of the Distribution Company TSA as a result of a Distribution Company default thereunder, Purchaser shall have the right, exercisable in its sole discretion, to assume the rights and obligations (subject to the adjustment set forth in Section 8.2) of Distribution Company under the Distribution Company TSA for the remainder of the term thereunder by written notice to Owner; provided that Purchaser shall have no obligations for amounts owed by Distribution Company to Owner prior to Purchaser’s assumption in accordance with this Section 14.8(a), including any amounts owed as a result of a Distribution Company default thereunder, and provided that Hydro-Québec shall execute and deliver an amendment to the Hydro-Québec Guaranty, in form and substance reasonably satisfactory to Owner, to guarantee such assumed obligations.

(b)During any suspension of all or part of Owner’s obligations or Distribution Company’s rights under the Distribution Company TSA, Purchaser shall have the right, exercisable in its sole discretion, to assume the rights and obligations (subject to the adjustment set forth in Section 8.2) of Distribution Company under the Distribution Company TSA by written notice to Owner, and, in the event Purchaser elects to assume such Distribution Company’s obligations, Owner shall thereafter resume performance of its obligations thereunder. For the avoidance of doubt, the exercise by Purchaser of any rights hereunder shall be without prejudice to the rights of Purchaser under the PPA.

Section 14.9Disputes. Any Dispute over whether or not an Owner Default or Purchaser Default has occurred shall be resolved in accordance with Article XVII.

Article XV

FORCE MAJEURE

Section 15.1Definition; Conditions.

(a)The term “Force Majeure” means an event or circumstance (i) that is not within the reasonable control of the Party claiming its occurrence; (ii) that could not have been prevented or avoided by such Party through the exercise of reasonable diligence and (iii) that prohibits or prevents such Party from performing its obligations under this Agreement. Under no circumstances shall Force Majeure include (w) any full or partial curtailment in the operation of the NECEC Transmission Line that is caused by or arises from a mechanical or equipment breakdown or other mishap or events or conditions attributable to normal wear and tear or flaws of the NECEC Transmission Line, unless such curtailment or mishap is caused by one of the following: acts of God such as floods, hurricanes, tornados, or other significantly unusual and abnormal weather conditions, such as severe blizzards and severe ice storms; sabotage; terrorism or war; national or regional general strikes, lockouts or other labor disputes, (x) any occurrence or event that increases the costs or causes an economic hardship to a Party but is not otherwise a Force Majeure, (y) Owner’s ability to sell transmission service involving the NECEC Transmission Line at a price greater than that set out in this Agreement or (z) Purchaser’s ability to procure transmission service at a price lower than that provided in this Agreement or Purchaser’s ability to sell generation at a price higher than that provided in the PPA. In addition, a delay or inability to perform attributable to a Party’s lack of preparation, a Party’s failure to timely obtain and maintain all necessary permits (excepting the Regulatory Approval other than the obligations to file for Regulatory Approval) or qualifications, any delay or failure of Owner to obtain the Owner Approvals or of Purchaser to obtain the Canadian Approvals, a failure to satisfy contractual conditions or commitments, or lack or deficiency in funding or other resources shall each not constitute a Force Majeure or be the basis for a claim of Force Majeure. Neither Party may raise a claim of Force Majeure based in whole or in part on the failure of Purchaser to fulfill any of its obligations under the PPA (including related to the availability of the Québec Line) unless such failure is due to “force majeure” or “uncontrollable force” or a similar term as defined under the PPA.

(b)Subject to Section 15.1(a), if a Party is unable, wholly or in part, by Force Majeure to perform its obligations under this Agreement, such performance shall be excused and suspended so long as the circumstances that give rise to such inability exist or would exist if the Party claiming the Force Majeure used commercially reasonable efforts to cure such circumstances, but for no longer period. The Party whose performance is affected shall give prompt notice thereof to the other Party; such notice may be given orally or in writing but, if given orally, it shall be promptly confirmed in writing, providing details regarding the nature, extent and expected duration of the Force Majeure, its anticipated effect on the ability of such Party to perform its obligations under this Agreement, and the estimated duration of any interruption in service or other adverse effects resulting from such Force Majeure, and shall be updated or supplemented to keep the other Party advised of the effect and remedial measures being undertaken to overcome

the Force Majeure. Such inability to perform shall be promptly corrected to the extent it may be corrected through the exercise of due diligence consistent with Good Utility Practice. Neither Party shall be liable for any losses or damages arising out of a suspension of performance that occurs because of Force Majeure. Notwithstanding any such suspension of performance, Purchaser shall be obligated to make Transmission Service Payments as though Firm Transmission Service was then being provided at or greater than the Minimum Average Availability.

(c)Notwithstanding the foregoing, if the Force Majeure prevents full or partial performance under this Agreement for a period of twelve (12) consecutive months or more, the Party whose performance is not prevented by Force Majeure shall have the right to terminate this Agreement upon written notice to the other Party and without further recourse, provided, however, that if (i) Owner presents a request to delay termination of this Agreement for a period not to exceed twelve (12) months, together with a detailed plan reasonably acceptable to Purchaser and Distribution Company (including reasonably satisfactory evidence of Owner’s financial and technical capability to timely effectuate such plan) to restore the capability of the NECEC Transmission Line to provide Firm Transmission Service in full within such period, to Purchaser and Distribution Company before the end of a period in which Owner’s provision of Firm Transmission Service has been prevented in whole or in part by an event of Force Majeure, Purchaser shall forbear terminating this Agreement under this clause (c) for such period, provided that, during any such period, Purchaser’s obligation to make Transmission Service Payments shall be reduced to the extent Firm Transmission Service is then being provided at less than the Minimum Average Availability. In the event Owner is not providing Firm Transmission Service in full at the end of such period of forbearance, or if Owner fails to exercise diligent, commercially reasonable efforts consistent with Good Utility Practice to timely effectuate such plan, Purchaser may terminate this Agreement under this clause (c). In no event will any delay or failure of performance caused by any conditions or events of Force Majeure extend this Agreement beyond its stated Term.

DISPUTE RESOLUTION

Section 17.1Consultation.

(a)The Parties shall initially attempt to resolve any Dispute through consultations between the Parties. Subject to Section 17.2 and except as expressly provided otherwise in this Agreement, if a Dispute has not been timely resolved pursuant to this clause (a) within fifteen (15) Business Days after written notice of such Dispute has been given, then either Party may seek to resolve such Dispute in the courts of the Commonwealth of Massachusetts or a U.S. District Court in the Commonwealth of Massachusetts and any appellate court from any thereof that has subject matter jurisdiction; provided, however, if the Dispute is subject to Section 17.2, then either Party may elect to proceed with the mediation through FERC's Dispute Resolution Service. If one Party fails to participate in the consultations provided for in this Section 17.1, the other Party can initiate mediation prior to the expiration of the fifteen (15) Business Days. Unless otherwise agreed, the Parties will select a mediator from the FERC panel. The Parties may, by written agreement signed by both Parties, alter any time deadline, location(s) for meeting(s) or procedure outlined herein or in FERC’s rules for mediation. The procedure specified herein shall be the sole and exclusive procedure for the resolution of Disputes.

(b)All negotiations, consultations, and mediations pursuant to this Section 17.1 shall be deemed to be confidential and shall be treated as compromise and settlement negotiations, and no evidence with regard to any proposal made during such negotiations, consultations or mediations shall be admissible in any FERC proceeding or filing under Section 17.2 or in any other judicial or other proceeding.

(a)In the event a Dispute over any matter is not resolved in accordance with Section 17.1, either Party shall have the right to file for relief with FERC to the extent that matter is within the primary or exclusive jurisdiction of the FERC. Nothing contained in this Agreement shall be construed as precluding a Party from filing any answer, protest or other opposition to any FERC filing made by the other Party, unless expressly prohibited under the terms of this Agreement.

(b)In the event any Dispute is submitted to FERC for resolution as provided in Section 17.2(a), the Party submitting the Dispute to FERC shall be responsible for providing written notice of such filing to the other Interested Parties. Unless both Parties agree that the Dispute does not implicate any of the Proposal Agreements other than this Agreement, each Party consents and agrees that (i) each Interested Party is an interested party in the Dispute and (ii) in order to avoid inconsistent interpretations and adjudications of the Proposal Agreements, any Interested Party may, without objection from any other Interested Party, whether by means of joinder, consolidation or otherwise, submit such matters as it considers sufficiently related to the Dispute to FERC to be jointly determined by FERC with the Dispute. Notwithstanding the foregoing, in the event FERC determines that it does not have the jurisdiction to, or otherwise does not want to, hear or determine any portion of a Dispute or other matter so referred to FERC, either Party may seek to resolve such Dispute in the courts of the Commonwealth of Massachusetts or a U.S. District Court in the Commonwealth of Massachusetts and any appellate court from any thereof that has subject matter jurisdiction.

Section 17.3Consent to Jurisdiction. Subject to Section 17.2, each Party agrees that any legal action or proceeding with respect to or arising out of this Agreement or any other Proposal Agreement shall be brought in or removed to the courts of the Commonwealth of Massachusetts or a U.S. District Court in the Commonwealth of Massachusetts that has subject matter jurisdiction and any appellate court from any thereof. By execution and delivery of this Agreement, each Party hereby accepts for itself and in respect of its property, generally and unconditionally, the jurisdiction of the aforesaid courts. The Parties irrevocably consent to the service of process out of any of the aforementioned courts in any such action or proceeding by the mailing of copies thereof by registered or certified airmail, postage prepaid, to the applicable Party at its respective addresses for notices as specified in Section 23.4. Nothing herein shall affect the right to serve process in any other manner permitted by law. Each Party hereby waives any right to stay or dismiss any action or proceeding under or in connection with this Agreement or any other Proposal Agreement brought before the foregoing courts on the basis of forum non-conveniens.

Section 17.4WAIVER OF JURY TRIAL. EACH PARTY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL ACTION, PROCEEDING, CAUSE OF ACTION, OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

In addition, to the extent any third party, or FERC acting sua sponte, seeks to amend or otherwise modify, or requests FERC to amend or otherwise modify, any provision of this Agreement, the standard of review for any proposed amendment or other modification shall be the “public interest” standard of review set forth in United Gas Pipe Line Co. v.

Section 19.2Change in ISO-NE Rules; Change in Applicable Law or Accounting Treatment.

(a)This Agreement is subject to the ISO-NE Rules. If, during the Term, any ISO-NE Rule is terminated, modified or amended, or is otherwise no longer applicable, resulting in a material alteration of a material right or obligation of a Party hereunder, the Parties agree to negotiate in good faith in an attempt to amend or clarify this Agreement to embody the Parties’ original intent regarding their respective rights and obligations under this Agreement; provided that neither Party shall have any obligation to agree to any particular amendment or clarification of this Agreement. The intent of the Parties is that any such amendment or clarification reflect, as closely as possible, the intent, substance and effect of the ISO-NE Rule being replaced, modified, amended or made inapplicable as such ISO-NE Rule was in effect prior to such termination,

modification, amendment or inapplicability; provided that such amendment or clarification shall not in any event alter (i) the purchase and sale obligations of the Parties pursuant to this Agreement or (ii) the Transmission Service Payment. In the event the Parties cannot agree upon such amendments within sixty (60) days after such ISO-NE Rule or ISO-NE Practice change described above, the Dispute shall be resolved in accordance with Article XVII.

(b)If, during the Term, there is a change in Applicable Law (other than tax laws or regulations) or accounting standards or rules or a change in the interpretation or applicability thereof that would result in a (A) material adverse balance sheet or creditworthiness impacts on Purchaser associated with this Agreement or the amounts paid for Firm Transmission Service purchased hereunder, or (B) an adverse impact on the economic benefits (including those stemming from the fiscal conditions provided for herein) that any Party enjoys under this Agreement or that are provided for herein for any Party during the Term, the Parties shall use commercially reasonable efforts to agree to an amendment to the Agreement to avoid or mitigate such impacts and restore the economic benefits to each affected Party; provided that such amendment mitigates any material adverse effect(s) on each non-affected Party (as identified by each such Party, acting reasonably) that could reasonably be expected to result from such amendment, but only to the extent that such mitigation can be accomplished in a manner that is consistent with the purpose of such amendment. In the event the Parties cannot agree on an amendment in accordance with this Section 19.2(b), the Dispute shall be resolved in accordance with Article XVII.

(c)Upon a determination by a court or regulatory body having jurisdiction over this Agreement or any of the Parties, or over the establishment and enforcement of any of the statutes or regulations or orders or actions of regulatory agencies (including the MDPU) supporting this Agreement or the rights or obligations of the Parties hereunder that any of the statutes or regulations supporting this Agreement or the rights or obligations of the Parties hereunder, or orders of or actions of regulatory agencies (including the MDPU) implementing such statutes or regulations, or this Agreement on its face or as applied, violates any Applicable Law (including the State or Federal Constitution) (an “Adverse Determination”), each Party shall have the right to suspend performance under this Agreement without liability. Owner may provide transmission service to a third party during any period of time for which Purchaser suspends payments under this Section 19.2(c). Upon an Adverse Determination becoming final and non-appealable, this Agreement shall be rendered null and void.

(d)For the avoidance of doubt, it is understood that the provisions of Article XVII regarding dispute resolution apply to any Dispute under this Article XIX.

INDEMNIFICATION

Section 20.1Purchaser Indemnity. Purchaser shall indemnify, defend and hold harmless Owner and Owner’s Affiliates and their respective officers, directors, shareholders, managers, members, partners, agents, employees, representatives, and permitted successors and assigns (each, an “Owner Indemnified Party”) from and against any and all claims, demands, suits, proceedings, judgments, losses, liabilities or damages, in each case, resulting from any third-party claims, together with any costs and expenses (including reasonable attorneys’ fees) incurred by any such Owner Indemnified Party, and arising out of the negligence, willful misconduct or criminal misconduct of Purchaser or its agents. Purchaser shall have no obligations under the immediately preceding sentence to the extent any claims, demands, suits, proceedings, judgments, losses, liabilities, damages, costs and expenses (including reasonable attorneys’ fees) incurred by any such Owner Indemnified Party are caused by or arise from the negligence, willful misconduct or criminal misconduct of, or breach or default of contract by, an Owner Indemnified Party. This Section 20.1 shall not apply to any claims for delay damages, cover damages, termination payments or other liquidated damages, in each case, that are asserted by any RFP Sponsor under the PPA, the Additional PPAs, the Distribution Company TSA or the Additional RFP Sponsor TSAs.

Section 20.2Owner Indemnity. Owner shall indemnify, defend and hold harmless Purchaser and Purchaser’s Affiliates and their respective officers, directors, shareholders, managers, members, partners, agents, employees, representatives and permitted successors and assigns (each, a “Purchaser Indemnified Party”) from and against any and all claims, demands, suits, proceedings, judgments, losses, liabilities or damages, in each case, resulting from any third-party claims, together with any costs and expenses (including reasonable attorneys’ fees) incurred by any such Purchaser Indemnified Party, including any such liabilities incurred by a Purchaser Indemnified Party under the PPA, and arising out of the negligence, willful misconduct or criminal misconduct of Owner or its agents, including such claims, costs and expenses arising from environmental liabilities or from property damage, in each case to the extent related to the NECEC Transmission Line. Owner shall have no obligations under the immediately preceding sentence to the extent any claims, demands, suits, proceedings, judgments, losses, liabilities, damages, costs and expenses (including reasonable attorneys’ fees) incurred by any such Purchaser Indemnified Party are caused by or arise from the negligence, willful misconduct or criminal misconduct of, or breach or default of contract by, a Purchaser Indemnified Party. This Section 20.2 shall not apply to any claims for delay damages, cover damages, termination payments or other liquidated damages, in each case, that are asserted by any RFP Sponsor under the PPA, the Additional PPAs, the Distribution Company TSA or the Additional RFP Sponsor TSAs.

Section 20.3[Intentionally Omitted].

Section 20.4Procedures. Promptly after the receipt by any Person seeking indemnification under this Article XX (the “Indemnified Party”) of written notice of the assertion of any claim by a third party with respect to any matter in respect of which indemnification may be sought hereunder (a “Third Party Claim”), the Indemnified Party shall give written notice (the “Indemnification Notice”) to the Party from which indemnification is sought (the “Indemnifying Party”), and shall thereafter keep the Indemnifying Party reasonably informed with respect thereto; provided, however, that the failure of the Indemnified Party to give the Indemnifying Party notice as provided herein shall not relieve the Indemnifying Party of any of its obligations hereunder, except to the extent that the Indemnifying Party is materially prejudiced by such failure. The Indemnifying Party shall be entitled to assume the defense of any Third Party Claim by written notice to the Indemnified Party of such intention given within thirty (30) days after the receipt by the Indemnifying Party of the Indemnification Notice; provided, however, that counsel selected by the Indemnifying Party shall be reasonably satisfactory to the Indemnified Party. The Indemnifying Party shall be liable for the fees and expenses of counsel employed by the Indemnified Party for any period during which the Indemnifying Party has not assumed the defense of any Third Party Claim (other than during any period during which the Indemnified Party has failed to give notice of such Third Party Claim as provided above). If the Indemnifying Party shall assume the defense of the Third Party Claim, then the Indemnifying Party shall not compromise or settle such Third Party Claim without the prior written consent of the Indemnified Party, which consent shall not be unreasonably withheld, delayed or conditioned; provided, however, that the Indemnified Party shall have no obligation to consent to any settlement that (a) does not include, as an unconditional term thereof, the giving by the claimant or the plaintiff of a release of the Indemnified Party from all liability with respect to such Third Party Claim or (b) involves the imposition of equitable remedies or the imposition of any material obligations on such Indemnified Party other than financial obligations for which such Indemnified Party is indemnified hereunder. As long as the Indemnifying Party is contesting any such Third Party Claim on a timely basis, the Indemnified Party shall not pay, compromise or settle any claims brought under such Third Party Claim. Notwithstanding the assumption by the Indemnifying Party of the defense of any Third Party Claim as provided in this Section 20.4, the Indemnified Party shall be permitted to participate in the defense of such Third Party Claim and to employ counsel at its own expense (it being understood that the Indemnifying Party controls such defense); provided, however, that, if the defendants in any Third Party Claim shall include both an Indemnifying Party and any Indemnified Party, and such Indemnified Party shall have reasonably concluded that counsel selected by the Indemnifying Party has a conflict of interest because of the availability of different or additional defenses to such Indemnified Party, such Indemnified Party shall then have the right to select separate counsel to participate in the defense of such Third Party Claim on its behalf, at the expense of the Indemnifying Party; provided that the Indemnifying Party shall not be obligated to pay the expenses of more than one separate counsel for all Indemnified Parties, taken together.

Section 20.5Defenses. If the Indemnifying Party shall fail to notify the Indemnified Party of its desire to assume the defense of any Third Party Claim within the prescribed period of time, or shall notify the Indemnified Party that it will not assume the defense of any such Third Party Claim, then the Indemnified Party may assume the defense of any such Third Party Claim, in which case it may do so acting in good faith and otherwise in such manner as it may deem appropriate, and the Indemnifying Party shall be bound by any determination made in such Third Party Claim.

Section 20.6Cooperation. The Indemnified Party and the Indemnifying Party shall each cooperate fully (and shall each cause its Affiliates to cooperate fully) with the other in the defense of any Third Party Claim pursuant to this Article XX. Without limiting the generality of the foregoing, each such Person shall furnish the other such Person (at the expense of the Indemnifying Party) with such documentary or other evidence as is then in its or any of its Affiliates’ possession, as may reasonably be requested by the other Person for the purpose of defending against any such Third Party Claim.

Section 20.7Recovery. The amount of any indemnity hereunder shall be reduced by any insurance proceeds actually recovered by the Indemnified Party in connection with the Third Party Claim. If at any time subsequent to the receipt by an Indemnified Party of an indemnity payment hereunder, such Indemnified Party (or any Affiliate thereof) receives any recovery, settlement or other similar payment with respect to the Third Party Claim for which it received such indemnity payment (a “Recovery”), such Indemnified Party shall then promptly pay to the Indemnifying Party the amount of such Recovery, less any expenses incurred by such Indemnified Party (or its Affiliates) in connection with such Recovery, but in no event shall any such payment exceed the amount of such indemnity payment.

Section 20.8Subrogation. To the extent the Indemnifying Party makes or is required to make any indemnity payment to the Indemnified Party, the Indemnifying Party shall be entitled to exercise, and shall be subrogated to, any rights and remedies (including rights of indemnity, rights of contribution and other rights of recovery) that the Indemnified Party or any of its Affiliates may have against any other Person with respect thereto, whether directly or indirectly related. The Indemnified Party shall permit the Indemnifying Party to use the name of the Indemnified Party and the names of the Indemnified Party’s Affiliates in any transaction or in any proceeding or other matter involving any of such rights or remedies; and the Indemnified Party shall take such actions as the Indemnifying Party may reasonably request for the purpose of enabling the Indemnifying Party to perfect or exercise its right of subrogation hereunder.

		(Contract Capacity x 0.90)

Where A =		∑ Hourly Availability for all hours in such month
Where A =		∑ Hours in such month

For purposes of calculating A, Excused Outages (for which Owner is paid full Transmission Service Payments pursuant to the terms of the Agreement) will be regarded as hours in which one hundred percent (100%) of Contract Capacity was provided.

Attachment H

Refund Calculation

This example is intended to illustrate the methodology for the calculation of a subsequent refund of a late payment. This example and the numbers used in this example are purely illustrative and are in no way intended to supersede any part of the Agreement, including Section 13.3.

Assumptions

•

Interest Rate = 12 percent per annum (compounded monthly)

June 2043 Billing


Invoice Amount	$1,000
Date of Invoice	June 1, 2043
Due Date	June 15, 2043
Payment Date	July 1, 2043

The total amount due on the date of payment is $1,005, which amount is computed by adding $1,000 (the original amount invoiced) and $5 (the ½ month late interest fee).

Subsequent Refund

If later, on July 1, 2044, the aforesaid payment is required to be refunded, the refund will equal the $1,000 payment made on July 1, 2043 (the original amount invoiced), plus the interest accrued on that $1,000 payment from the due date of June 15, 2043 to the date of refund on July 1, 2044. To ensure that the refund does not double recover interest, the following language has been included in Section 13.3 of the Agreement: “[I]f all or a portion of the amount [here, the $1,000 payment due on June 15, 2043] to which such interest relates [here, the $5 late interest fee] is later refunded pursuant to this Agreement [here, on July 1, 2044], then, in calculating that refund, such interest [here, $5] shall not be included in the refund.”

At the Guarantor's request, the Beneficiary shall provide the Guarantor with any useful information respecting the content and the terms and conditions of the obligations and liabilities of HQUS with regard to the Agreements and a statement of account with details of xxxxxxxx and payments.

Article 2. Nature du Cautionnement. Les obligations qui incombent à la Caution en vertu des présentes sont assujetties à toutes les clauses contractuelles de protection, de limitation, de renonciation et d’exclusion et à tous les droits dont bénéficie HQUS en vertu des Conventions, et la Caution bénéficie de toute modification apportée aux Conventions, de toute renonciation à ses dispositions et de tout consentement donné à l’inexécution d’une de ses dispositions dans la mesure où HQUS aurait eu droit à ces avantages, le cas échéant. Néanmoins, le

présent Cautionnement ne peut être considéré comme éteint ni modifié d’aucune façon du fait de l’existence, de la validité, de l’opposabilité, de la perfection ou de xx xxxxxx de toute sûreté donnée en garantie d’obligations quelconques de HQUS découlant des Conventions.

Section 2. Nature of Guarantee. The Guarantor's obligations hereunder shall be subject to all the contractual protections, limitations, waivers, exclusions and rights which HQUS has under the Agreements, and the Guarantor shall be entitled to the benefits of any modification of, amendment to, waiver of or consent to departure from the Agreements to the extent, if any, HQUS would have been entitled to such benefits. Nonetheless, this Guaranty shall not be deemed discharged, impaired or affected by the existence, validity, enforceability, perfection, or extent of any collateral for any obligations under the Agreements of HQUS.

Article 3. Consentements, renonciations et renouvellements. La Caution convient que le Bénéficiaire peut en tout temps, soit avant ou après l'échéance, sans xxxxxx d’avis à la Caution ou obtenir d’autre consentement de celle‑ci, prolonger le délai de paiement d’obligations de paiement découlant des Conventions, échanger ou remettre toute sûreté donnée à leur égard ou encore renouveler les Conventions, et qu'il peut également conclure toute entente avec HQUS ou avec toute autre partie aux obligations prévues aux Conventions, toute personne responsable à l'égard de ces obligations ou toute personne ayant un intérêt dans celles-ci, relativement au prolongement, au renouvellement, au paiement, à la décharge ou à la libération de ces obligations ou encore à la conclusion d'un compromis visant celles-ci, en tout ou en partie, ou relativement à toute modification des conditions y afférentes ou des conditions de toute convention passée entre le Bénéficiaire et HQUS ou n'importe laquelle de ces autres parties ou personnes, sans toucher le présent Cautionnement de quelque manière que ce soit. La Caution convient que le Bénéficiaire peut recourir à elle relativement au paiement des obligations découlant des Conventions, que le Bénéficiaire ait ou non recouru à une sûreté accessoire ou qu'il ait ou non exercé un recours contre tout autre débiteur principal ou secondaire de n'importe laquelle des obligations découlant des Conventions.

Section 3. Consents, Waivers and Renewals. The Guarantor agrees that the Beneficiary may at any time and from time to time, either before or after maturity thereof, without notice to or further consent of the Guarantor, extend the time of payment of any payment obligations under the Agreements, exchange or surrender any collateral therefor, or renew the Agreements, and may also make any agreement with HQUS or with any other party to, or person liable for, or any of the obligations contemplated in the Agreements, or interested therein, for the extension, renewal, payment, compromise, discharge or release thereof, in whole or in part, or for any modification of the terms thereof or of any agreement between the Beneficiary and HQUS or any such other party or person, without in any way impairing or affecting this Guaranty. The Guarantor agrees that the Beneficiary may resort to the Guarantor for payment in virtue of the Agreements, whether or not the Beneficiary shall have resorted to any collateral security, or shall have proceeded against any other obligor principally or secondarily obligated with respect to any of the obligations in virtue of the Agreements.

Article 4. Subrogation. Dans tous les cas, y compris l’insolvabilité de HQUS, la Caution n'exercera aucun droit qu'elle peut acquérir par voie de subrogation tant que toutes les sommes dues au Bénéficiaire en vertu des Conventions n'auront pas été payées intégralement. Sous réserve de ce qui précède, sur paiement de toutes les obligations liées aux Conventions, la Caution sera subrogée dans les droits du Bénéficiaire contre HQUS et le Bénéficiaire s’engage à prendre, aux frais de la Caution, les mesures que la Caution pourra raisonnablement lui demander de prendre pour faire valoir cette subrogation.

Section 4. Subrogation. In any case, including HQUS's insolvency, the Guarantor will not exercise any rights, which it may acquire by way of subrogation, before all amounts due to the Beneficiary under the Agreements shall have been paid in full. Subject to the foregoing, upon payment of all the obligations related to the Agreements, the Guarantor shall be subrogated to the rights of the Beneficiary against HQUS and the Beneficiary agrees to take, at the Guarantor's expense, such steps as the Guarantor may reasonably request to implement such subrogation.

Article 5. Droits cumulatifs. Aucune omission de la part du Bénéficiaire d'exercer tout droit, recours ou pouvoir conféré par les présentes, et aucun retard à le faire ne constituent une renonciation à cet égard, et l'exercice unique ou partiel par le Bénéficiaire d'un droit, recours ou pouvoir quelconque conféré par les présentes n'empêche pas l'exercice ultérieur de tout droit, recours ou pouvoir. Tous et chacun des droits, recours et pouvoirs qui sont conférés par les présentes au Bénéficiaire ou dont celui-ci peut se prévaloir en vertu de la loi ou d'une autre convention sont cumulatifs et non exclusifs, et ils peuvent être exercés par le Bénéficiaire de temps à autre.		Section 5. Cumulative Rights. No failure on the part of the Beneficiary to exercise, and no delay in exercising any right, remedy or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise by the Beneficiary of any right, remedy or power hereunder preclude any other future exercise of any right, remedy or power. Each and every right, remedy and power hereby granted to the Beneficiary or allowed to it by law or other agreement shall be cumulative and not exclusive of any other, and may be exercised by the Beneficiary from time to time.
Article 6. Renonciation aux avis. La Caution renonce à l'avis d'acceptation du présent Cautionnement, ainsi qu'à tout avis de refus, de présentation et de demande, sauf comme il est indiqué à l'article 1, à tout avis d’exercice d’un droit et à tous autres avis, quels qu'ils soient.
