(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:

(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 7.3.1 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 RFP Sponsor TSAs during the term of the RFP Sponsor TSAs, 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 pursuant to the Purchaser TSAs 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 7.3.3 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 20.2, (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. The Parties expressly intend and agree that Purchaser’s transmission service under this Agreement shall be reduced before any reductions are applied to any RFP Sponsor’s transmission service under any RFP Sponsor TSA. Except as otherwise set forth in this Section 7.4, the Parties expressly intend and agree that any outages or reductions in Total Transfer Capability shall be borne equitably by all transmission rights holders served by the NECEC Transmission Line (including Owner, if applicable), and Owner acknowledges and agrees that it will not reduce the Firm Transmission Service available to Purchaser in an unduly discriminatory manner as compared with any other transmission rights holder served by the NECEC Transmission Line (including Owner, if applicable).

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 PPAs, 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.

Section 8.1Transmission Service Payments. During the period beginning on the Commercial Operation Date and ending on the twentieth (20th) anniversary of the Commercial Operation Date (unless earlier terminated) (the “Initial 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 “Initial Transmission Service Payment”) on a monthly basis in an amount calculated as set forth in Attachment K pursuant to invoices delivered by Owner to Purchaser. 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 “Second 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 “Second 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 Initial Transmission Service Payment or the Second Transmission Service Payment, as applicable, 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 Initial Transmission Service Payment or the Second 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. The Initial Purchaser Term and the Second Purchaser Term shall mean collectively the “Purchaser Term.” “Transmission Service Payment” means, as the context requires, the Initial Transmission Service Payment or the Second Transmission Service Payment.

Section 8.2Elective 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 PPAs, 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 PPAs), as it may be extended pursuant to Sections 3.1(c) through 3.1(f) of the PPAs 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 Purchaser Term. Notwithstanding the foregoing, if during the Purchaser 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.

(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.

Section 10.1Resale Rights of Purchaser. If and to the extent Purchaser determines from time to time, and in its sole discretion, that the transmission capacity available to Purchaser 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 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.

(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 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.

(a)Purchaser shall be entitled during the Purchaser Term to the 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 the 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.

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.

(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 Purchaser TSAs.

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 (d), clause (e) or clause (f):

(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.

(c)Purchaser’s failure to perform or comply with any of its obligations under this Agreement, other than those described in clauses (a) or (b) above, in each case, in any material respect, and, if such failure is susceptible to cure, such failure continues for thirty (30) days after the receipt by Purchaser of written notice thereof from Owner, unless such cure shall reasonably require a longer period, in which case Purchaser shall be provided an additional thirty (30) days to complete such cure so long as Purchaser has promptly commenced such cure and thereafter diligently pursues such cure.

(d)Any representation or warranty made by Purchaser in this Agreement is false or misleading at the time made in any material respect.

(f)An Event of Default (as defined in any PPA) by Purchaser under any PPA that does not result from a TSA Delivery Shortfall (as defined in any PPA) or a Transmission Delay (as defined in any PPA),or a Purchaser Default (as defined in any Purchaser TSA) occurs and is continuing.

Section 14.3Owner 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 Owner under this Agreement (an “Owner Default”); provided that an event of Force Majeure shall not excuse an event described in clause (a), clause (g) or clause (h):

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

(b)Owner’s failure to satisfy (other than as a result of a Purchaser Delay) any of the Critical Milestones in clauses (i), (iii), (iv), (v), or (vii) of Section 4.1(a) by the dates set forth therefor, as the same may be extended in accordance with Section 4.1(c), Section 4.1(d) or Section 4.1(e).

(c)Owner’s failure to comply in any material respect with the provisions of Section 5.1.1(a)(ii) and, if such failure is susceptible to cure, such failure continues for thirty (30) days after receipt by Owner of written notice thereof from Purchaser, unless such cure shall reasonably require a longer period, in which case Owner shall be provided an additional thirty (30) days to complete such cure so long as Owner has promptly commenced such cure and thereafter diligently pursues such cure.

(d)A Non-Excused Outage pursuant to which (A) the Hourly Availability of the NECEC Transmission Line is less than one hundred percent (100%) for more than ninety (90) consecutive days and the average Hourly Availability of the NECEC Transmission Line over each calendar month in which the ninety (90) consecutive days occur is less than the Minimum Average Availability for each such month (whether as a result of a physical condition, legal impediment or otherwise), or (B) the Hourly Availability of the NECEC Transmission Line is less than one hundred percent (100%) for more than hundred twenty (120) days in any twelve (12) month period and the average Hourly Availability of the NECEC Transmission Line over each calendar month in which any such day occurs is less than the Minimum Average Availability for each such month (whether as a result of a physical condition, legal impediment or otherwise) in each case, unless otherwise excused under Section 7.2, provided, however, that if (i) Owner presents to RFP Sponsors and Purchaser (during the Initial Purchaser Term) or Purchaser (during the Second Purchaser Term) before the end of a Non-Excused Outage that would otherwise constitute an Owner Default under this clause (d), a request to delay termination of this Agreement for a period not to exceed twelve (12) months, together with a detailed plan (including reasonably satisfactory evidence of Owner’s financial and technical capability to timely effectuate such plan) acceptable to RFP Sponsors and Purchaser (during the Initial Purchaser Term) or Purchaser (during the Second Purchaser Term), each acting reasonably, to restore the capability of the NECEC Transmission Line to provide Firm Transmission Service in full within such period, and (ii) during the Initial Purchaser Term, Owner posts Credit Support with RFP Sponsors as set forth in Section 14.2(e) of the RFP Sponsor TSAs, Purchaser shall forbear terminating this Agreement under this clause (d) for such period, provided that, during any such period, Purchaser’s obligation to make Transmission Service Payments shall continue to 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, an Owner Default shall be deemed to have occurred and Purchaser shall have the rights and remedies set forth in Section 14.6 and Section 14.7 of the Purchaser TSAs.

(f)Owner’s failure to perform or comply with any of its obligations under this Agreement, other than those described in clauses (a), (b), (c) or (d) above, in each case, in any material respect, and, if such failure is susceptible to cure, such failure continues for thirty (30) days after the receipt by Owner of written notice thereof from Purchaser, unless such cure shall reasonably require a longer period, in which case Owner shall be provided an additional thirty (30) days to complete such cure so long as Owner has promptly commenced such cure and thereafter diligently pursues such cure.

(g)Any representation or warranty made by Owner in this Agreement is false or misleading at the time made in any material respect.

Section 14.11Modified Terms Applicable During Forbearance Period. In the event that Owner exercises its rights pursuant to Section 14.2(e) of the RFP Sponsor TSAs or Section 14.3(d) of this Agreement, during the continuation of the period of forbearance by Purchaser of its rights as contemplated by Section 14.3(d) of this Agreement or Section 14.2(e) of the RFP Sponsor TSAs, an additional $3 shall be available in clause (b) of the definition of Non-Excused Outage Payment for the calculation of such payment by Owner, and an additional Ten Million Dollars ($10,000,000) per Contract Year shall be available with respect to the limitation of liability contained in Section 7.3.1. If Owner is successful in providing Firm Transmission Service under this Agreement or Firm Transmission Service (as defined in the RFP Sponsor TSAs), as applicable, in full at or prior to the end of such period of forbearance, all such amounts shall revert at the time Firm Transmission Service or Firm Transmission Service (as defined in the RFP Sponsor TSAs), as applicable, is provided in full to the amounts applicable under this Agreement prior to Owner’s exercise of its rights under Section 14.3(d) of this Agreement or Section 14.2(e) of the RFP Sponsor TSAs.

(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. 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.

(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 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 RFP Sponsors (during the Initial Purchaser Term) or Purchaser (during the Second Purchaser Term) (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 RFP Sponsors (during the Initial Purchaser Term) or Purchaser (during the Second Purchaser Term) 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.

(d)A Party shall not be required to settle any strike, walkout, lockout or other labor dispute on terms that, in the sole judgment of such Party, are contrary to its interest. The settlement of strikes, walkouts, lockouts or other labor disputes shall be entirely within the discretion of the Party involved in such dispute.

Section 16.1Purchaser’s Guaranty. Concurrently with the execution of this Agreement, Purchaser shall cause Purchaser Guarantor to deliver to Owner a guaranty by Purchaser Guarantor of Purchaser’s payment obligations under this Agreement substantially in the form of Attachment J (the “Hydro-Québec Guaranty”).

Section 16.3Credit Downgrade Event. Purchaser Guarantor and Owner shall at all times meet the Credit Rating Requirements.

(a)In the event Owner fails to meet the Credit Rating Requirements, Owner shall promptly furnish to Purchaser, in an amount equal to the Proportionate Share multiplied by Two Hundred Fifty Million Dollars ($250,000,000), Additional Credit Support.

(b)In the event Purchaser Guarantor fails to meet the Credit Rating Requirements, Purchaser shall promptly furnish to Owner, in an amount equal to the Proportionate Share multiplied by Two Hundred Fifty Million Dollars ($250,000,000), Additional Credit Support.

(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.

(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.

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.

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.

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 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 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.

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 PPAs or the 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 PPAs, 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 PPAs or the RFP Sponsor TSAs.

Section 20.3Procedures. 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 20.3, 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 20.4Defenses. 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 20.5Cooperation. 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 20.6Recovery. 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 20.7Subrogation. 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.

Section 21.5NO OTHER REPRESENTATIONS OR WARRANTIES. THE REPRESENTATIONS AND WARRANTIES OF OWNER SET FORTH IN Section 21.1 AND Section 21.3 ARE OWNER’S SOLE REPRESENTATIONS AND WARRANTIES ASSOCIATED WITH THE NECEC TRANSMISSION LINE AND ARE MADE IN LIEU OF ALL OTHER REPRESENTATIONS, WARRANTIES, AND GUARANTEES, EXPRESS OR IMPLIED, ASSOCIATED WITH THE NECEC TRANSMISSION LINE, INCLUDING REPRESENTATIONS OR WARRANTIES AS TO MERCHANTABILITY, USAGE, SUITABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE.

Set forth below are, to the best of Purchaser’s knowledge, the Governmental Approvals and Third Party Consents, in each case, required to commence construction of the Québec Line:

Owner shall obtain and maintain with qualified insurers authorized to issue insurance of the types described below in the State of Maine.

During construction of the NECEC Transmission Line Owner shall maintain or effect to be maintained the following insurance coverages:

After the Commercial Operation Date Owner shall provide coverage both in terms of scope and limits of coverage that are in accordance with Good Utility Practice and the long-standing practice of Owner. Operational coverage shall include the following insurance types:

Note: At any time after the Commercial Operation Date Owner may choose, as far as it is consistent with Good Utility Practice, to self-insure on customary terms and conditions any coverage (or coverage part) where it meets any state or regulatory requirements of self-insurers.

In the event that a Transmission Service Payment is subject to reduction pursuant to Section 8.1, such reduced payment shall equal the Transmission Service Payment that would otherwise be payable under the Agreement for a particular month multiplied by the lesser of 1 or the following fraction:

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.

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.

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).

If later, on July 1, 2024, the aforesaid payment is required to be refunded, the refund will equal the $1,000 payment made on July 1, 2023 (the original amount invoiced), plus the interest accrued on that $1,000 payment from the due date of June 15, 2023 to the date of refund on July 1, 2024. 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, 2023] to which such interest relates [here, the $5 late interest fee] is later refunded pursuant to this Agreement [here, on July 1, 2024], then, in calculating that refund, such interest [here, $5] shall not be included in the refund.”

EN CONSÉQUENCE, eu égard à ce qui précède, la Caution s’entend avec le Bénéficiaire sur ce qui suit :		NOW THEREFORE, in consideration of the premises, the Guarantor hereby agrees with the Beneficiary as follows:

Article 1. Cautionnement à l’égard du paiement. La Caution garantit absolument, irrévocablement et inconditionnellement au Bénéficiaire, ses ayants droit et endossataires et cessionnaires, le prompt paiement à l’échéance de toutes les sommes dues actuellement et ultérieurement par HQUS au Bénéficiaire conformément aux Conventions, sur demande écrite du Bénéficiaire stipulant que HQUS a manqué à ses obligations découlant des Conventions et que la somme réclamée est due au Bénéficiaire; toutefois, la responsabilité qui incombe à la Caution en vertu du présent Cautionnement est limitée à la Somme Globale (telle que définie ci-dessous) majorée de tous les frais raisonnables engagés par le Bénéficiaire pour faire valoir ses droits contre la Caution en vertu du présent Cautionnement, y compris les honoraires d’avocats, frais de justice et coûts semblables. Aux fins du présent Cautionnement, la « Somme Globale » signifie : (a) CENT MILLIONS DE DOLLARS U.S. (U.S. $100,000,000) sur réception de l’Approbation Réglementaire (Regulatory Approval, tel que défini aux Conventions) ; (b) augmenté à DEUX CENT MILLIONS DE DOLLARS U.S. (U.S.$200,000,000) sur réception des Approbations du Propriétaire (Owner Approvals, tel que défini aux Conventions) ; (c) augmenté à DEUX CENT CINQUANTE MILLIONS DE DOLLARS U.S. (U.S.$250,000,000) commençant trente (30) jours avant le vingtième (20^e) anniversaire de la Commercial Operation Date (Commercial Operation Date, tel que défini aux Conventions) ; et (d) réduit à DEUX CENT MILLIONS DE DOLLARS U.S. (U.S.$200,000,000) à compter du trentième (30^e) anniversaire de la Commercial Operation Date (Commercial Operation Date, tel que défini aux Conventions).		Section 1. Payment Guaranty. The Guarantor absolutely, irrevocably, and unconditionally guarantees to the Beneficiary, its successors and endorsees and assignees, the prompt payment when due of all present and future amounts owed by HQUS to the Beneficiary in accordance with the Agreements, upon a written demand by the Beneficiary stating that HQUS has failed to fulfill its obligations and liabilities resulting from the Agreements and that the amount claimed is due and payable to the Beneficiary, provided that the liability of the Guarantor under this Guaranty shall be limited in the aggregate to the Maximum Amount (as hereinafter defined) plus all reasonable expenses incurred by the Beneficiary to enforce its rights against the Guarantor under this Guaranty including, without limitation, attorneys' fees, court costs and similar costs. For purposes of this Guaranty, the “Maximum Amount” shall mean: (a) ONE HUNDRED MILLION U.S.DOLLARS (U.S. $100,000,000) commencing on receipt of the Regulatory Approval (as defined in the Agreements); (b) increased to TWO HUNDRED MILLION U.S. DOLLARS (U.S. $200,000,000) commencing on receipt of the Owner Approvals (as defined in the Agreement) (c) increased to TWO HUNDRED AND FIFTY MILLION U.S. DOLLARS (U.S. $250,000,000) thirty (30) days prior to the twentieth (20^th) anniversary of the Commercial Operation Date (as defined in the Agreements); and (d) decreased to TWO HUNDRED MILLION U.S. DOLLARS (U.S. $200,000,000) on the thirtieth (30th) anniversary of the Commercial Operation Date (as defined in the Agreements).
À la demande de la Caution, le Bénéficiaire fournira à celle-ci tous les renseignements utiles se rapportant à la teneur et aux conditions des obligations de HQUS en ce qui concerne les Conventions ainsi qu’un relevé de compte détaillé relatif aux factures et aux paiements.		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 billings 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 la portée 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 donner 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.		Section 6. Waiver of Notice. The Guarantor waives notice of the acceptance of this Guaranty, notice of dishonor, presentment and demand, except as set forth in Section 1, notice of exercise of any right and all other notices whatsoever.
Article 7. Déclarations et garanties. La Caution fait les déclarations et donne les garanties suivantes : a) Elle est une société dûment organisée, elle existe validement, elle est en règle en vertu des lois du territoire où elle a été constituée en société et elle a en tant que société tous les pouvoirs nécessaires pour signer, livrer et exécuter le présent Cautionnement. b) La signature, la livraison et l'exécution du Cautionnement ont été et demeurent dûment autorisées par toutes les mesures nécessaires de la part de la Caution et ne violent aucune disposition de la loi ou des documents constitutifs de la Caution ni aucune restriction contractuelle liant la Caution ou ses actifs. c) Le Cautionnement constitue l'obligation juridique, valide et exécutoire de la Caution et il est susceptible d'exécution contre la Caution conformément à ses conditions, sous réserve, quant à l'exécution, de la législation en matière de faillite, d'insolvabilité et de réorganisation et de toute législation semblable et sous réserve des principes généraux d’equity.		Section 7. Representations and Warranties. The Guarantor represents and warrants that: a) It is a corporation duly organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation and has full corporate power to execute, deliver and perform this Guaranty. b) The execution, delivery and performance of the Guaranty have been and remain duly authorized by all necessary corporate action and do not contravene any provision of law or the Guarantor's constitutional documents or any contractual restriction binding on the Guarantor or its assets. c) The Guaranty constitutes a legal, valid and binding obligation of the Guarantor enforceable against the Guarantor in accordance with its terms, subject, as to enforcement, to bankruptcy, insolvency, reorganization and other similar laws and to general principles of equity.
Article 8. Compensation et demandes reconventionnel-les. La Caution est fondée à faire valoir tous les droits et moyens de défense que HQUS peut invoquer en vertu des Conventions, et peut notamment exiger toute compensation ou présenter toute demande reconventionnelle que HQUS ou une autre société du même groupe que la Caution peut ou pourrait invoquer. Toutefois, la responsabilité de la Caution en vertu Cautionnement n’est en rien modifiée en cas de faillite, d’insolvabilité, de dissolution ou de liquidation de HQUS.		Section 8. Setoff and Counterclaims. The Guarantor shall be entitled to assert all rights and defenses that HQUS may be entitled to under the Agreements, including, but not limited to, any setoff or counterclaims that HQUS or any other affiliate of the Guarantor is or may be entitled to. Notwithstanding the preceding sentence, the liability of the Guarantor under the Guaranty shall not be affected because of the bankruptcy, insolvency, dissolution or liquidation of HQUS.
Article 9. Résiliation. La présente garantie de paiement constitue un cautionnement continu en vigueur pendant la durée des Conventions jusqu’à l’exécution intégrale des obligations de HQUS en vertu des Conventions et au paiement intégral de toutes les obligations.		Section 9. Termination.

Toutefois, le Bénéficiaire peut céder ses droits, intérêts ou obligations découlant des présentes à un cessionnaire de ses droits en vertu des Conventions advenant une cession permise en vertu de ses dispositions.		Section 10. Assignment.

The Transmission Service Payment for a given calendar month shall be equal to the unit price per kW-month for the then-current Contract Year (the “Unit Price”), as set forth in the table below, multiplied by the Contract Capacity expressed in kW.

Contract Year	Unit Price ($/kW-month)
Contract Year 1	$9.16
Contract Year 2	$9.35
Contract Year 3	$9.53
Contract Year 4	$9.73
Contract Year 5	$9.92
Contract Year 6	$10.12
Contract Year 7	$10.32
Contract Year 8	$10.53
Contract Year 9	$10.74
Contract Year 10	$10.95
Contract Year 11	$11.17
Contract Year 12	$11.40
Contract Year 13	$11.62
Contract Year 14	$11.86
Contract Year 15	$12.09
Contract Year 16	$12.33
Contract Year 17	$12.58
Contract Year 18	$12.83
Contract Year 19	$13.09
Contract Year 20	$13.35

In the event the anniversary of the Commercial Operation Date falls within the middle of a calendar month (month M), the Unit Price for each month M shall be equal to: the Unit Price for the Contract Year that is ending (Contract Year Y), multiplied by the proportion of the days of the calendar month M that are part of that Contract Year Y, plus the Unit Price for the Contract Year that is beginning (Contract Year Y+1), multiplied by the proportion of the days of the calendar month M that are part of that Contract Year Y+1, the resulting calculation being rounded to the nearest cent.

Examples. For all examples, assume the Commercial Operation Date is December 13, 2022, with December being month M.

•Example 1. The Unit Price for the month of December 2022 is as follows: (($0 [no Transmission Service Payment prior to Contract Year 1] * 12/31 [proportion of days in December 2022 that are prior to Contract Year 1]) + ($9.16 [Unit Price for Contract Year 1] * 19/31 [proportion of days in December that are part of Contract Year 1])) = $5.61/kW-month.

•Example 2. The Unit Price for the month of December 2023 is as follows: (($9.16 [Unit Price for Contract Year 1] * 12/31 [proportion of days in December that are part of Contract Year 1]) + ($9.35 [Unit Price for Contract Year 2] * 19/31 [proportion of days in December that are part of Contract Year 2])) = $9.28/kW-month.

•Example 3. The Unit Price for the month of December 2041 is as follows: (($13.35 [Unit Price for Contract Year 20] * 12/31 [proportion of days in December that are part of Contract Year 20]) + ($0 [no Transmission Service Payment after Contract Year 20] * 19/31 [proportion of days in December that are after end of Contract Year 20])) = $5.17/kW-month.

		(Contract Capacity x 0.90)
1 -		minus (Contract Capacity x A)
		(Contract Capacity x 0.90)

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