NYISO’s satisfaction that the delay in meeting a Critical Path Milestone will not delay

8

SERVICE AGREEMENT NO. 2510

the Transmission Project’s In-Service Date beyond the Required Project In-Service Date, then the NYISO’s consent to extending the Critical Path Milestone date will not be
unreasonably withheld, conditioned, or delayed.  The NYISO’s written consent to a
revised Development Schedule proposed by the Developer will satisfy the amendment requirements in Article 15.8, and the NYISO will not be required to file the revised
Development Schedule with FERC.

3.3.5. Within fifteen (15) Calendar Days of the Developer’s discovery of a potential delay in

meeting an Advisory Milestone, the Developer shall inform the NYISO of the potential delay and describe the impact of the delay on meeting the Critical Path Milestones.  The Developer may extend an Advisory Milestone date upon informing the NYISO of such
change; provided, however, that if the change to the Advisory Milestone will delay a
Critical Path Milestone, the NYISO’s written consent to make such change is required as described in Article 3.3.4.

3.4. Modifications to Required Project In-Service Date

3.4.1. The Developer shall not make a change to the Required Project In-Service Date without

the prior written consent of the NYISO.  To request a change, the Developer must: (i)

accordance with the modified schedule.  If the Required Project In-Service Date is the
date prescribed by the NYPSC in its order identifying the Public Policy Transmission
Need or in a subsequent order, the Developer must also demonstrate that the NYPSC has
issued an order modifying its prescribed date.

3.4.2. The NYISO will promptly review Developer’s requested change to the Required Project

In-Service Date.  The Developer shall provide the NYISO with all required information
to assist the NYISO in making its determination and shall be responsible for the costs of
any study work the NYISO performs in making its determination.  If the Developer fails
to provide the NYISO with the information required to make its determination, the
NYISO shall not be obligated to make this determination.  The NYISO’s consent to
extend the Required Project In-Service Date will not be unreasonably withheld,
conditioned, or delayed if the Developer demonstrates to the NYISO’s satisfaction that:

(i) its proposed modified Required Project In-Service Date is reasonable in light of the
Public Policy Transmission Need, (ii) it has made reasonable progress against the
milestones set forth in the Development Schedule, and (iii) its proposed modified date

NYISO’s review and determination of material modifications to the Transmission Project under
Attachment P of the OATT.  The Developer may request that the NYISO review whether a
modification to the Transmission Project would constitute a Significant Modification.  The
Developer shall provide the NYISO with all required information to assist the NYISO in making
its determination regarding a Significant Modification and shall be responsible for the costs of
any study work the NYISO must perform in making its determination.  The NYISO’s consent to
the Significant Modification will not be unreasonably withheld, conditioned, or delayed if the
Developer demonstrates to the NYISO’s satisfaction that its proposed Significant Modification:

(i) does not impair the Transmission Project’s ability to satisfy the identified Public Policy

Transmission Need, (ii) does not delay the In-Service Date of the Transmission Project beyond
the Required Project In-Service Date, (iii) does not change the grounds upon which the NYISO
selected the Transmission Project as the more efficient or cost-effective transmission solution to
the identified Public Policy Transmission Need, and (iv) will not result in a significant adverse
impact to the reliability of the New York State Transmission System.  The NYISO’s
performance of this review shall not constitute its consent to delay the completion of any Critical
Path Milestone.

3.6.Billing and Payment

The NYISO shall charge, and the Developer shall pay, the actual costs of: (i) any study
work performed by the NYISO or its subcontractor(s) under Articles 3.3, 3.4, and 3.5, or (ii) any
assessment of the Transmission Project by the NYISO or its subcontractor(s) under Article 3.8.
The NYISO will invoice Developer on a monthly basis for the expenses incurred by the NYISO
each month, including estimated subcontractor costs, computed on a time and material basis.
The Developer shall pay invoiced amounts to the NYISO within thirty (30) Calendar Days of the
NYISO’s issuance of a monthly invoice.  In the event the Developer disputes an amount to be
paid, the Developer shall pay the disputed amount to the NYISO, pending resolution of the
dispute.  To the extent the dispute is resolved in the Developer’s favor, the NYISO will net the
disputed amount, including interest calculated from Developer’s date of payment at rates
applicable to refunds under FERC regulations, against any current amounts due from the
Developer and pay the balance to the Developer.  This Article 3.6 shall survive the termination,
expiration, or cancellation of this Agreement.

3.7.Project Monitoring

The Developer shall provide regular status reports to the NYISO in accordance with the monitoring requirements set forth in the Development Schedule, the Public Policy Transmission Planning Process Manual and Attachment Y of the OATT.

3.10.2. The creation of any subcontractor relationship shall not relieve the hiring Party of any of
its obligations under this Agreement.  The hiring Party shall be fully responsible to the
other Party for the acts or omissions of any subcontractor the hiring Party hires as if no
subcontract had been made.

15

SERVICE AGREEMENT NO. 2510

ARTICLE 7. BREACH AND DEFAULT

7.1.Breach

A Breach of this Agreement shall occur when: (i) the Developer notifies the NYISO in
writing that it will not proceed to develop the Transmission Project for reasons other than those
set forth in Articles 8.1(i) through (iv); (ii) the Developer fails to meet a Critical Path Milestone,
as the milestone may be extended with the agreement of the NYISO under Article 3.3.4 of this
Agreement, set forth in the Development Schedule in Appendix C to this Agreement; (iii) the
Developer makes a Significant Modification to the Transmission Project without the prior

written consent of the NYISO; (iv) the Developer fails to pay a monthly invoice within the
timeframe set forth in Article 3.6; (v) the Developer misrepresents a material fact of its
representations and warranties set forth in Article 12; (vi) a Party assigns this Agreement in a
manner inconsistent with the terms of Article 10 of this Agreement; (vii) the Developer fails to
comply with any other material term or condition of this Agreement; (viii) a custodian, receiver,
trustee or liquidator of the Developer, or of all or substantially all of the assets of the Developer,
is appointed in any proceeding brought by the Developer; or (ix) any such custodian, receiver,
trustee, or liquidator is appointed in any proceeding brought against the Developer that is not
discharged within ninety (90) Days after such appointment, or if the Developer consents to or
acquiesces in such appointment.  A Breach shall not occur as a result of a Force Majeure event in
accordance with Article 15.5.  A Breach shall also not occur as a result of a delay caused by a
Connecting Transmission Owner or an Affected System Operator.

7.2.Default

Upon a Breach, the non-Breaching Party shall give written notice of the Breach to the
Breaching Party describing in reasonable detail the nature of the Breach and, where known and
applicable, the steps necessary to cure such Breach, including whether and what such steps must
be accomplished to complete the Transmission Project by the Required Project In-Service Date.
The Breaching Party shall have thirty (30) Calendar Days from receipt of the Breach notice to
cure the Breach, or such other period of time as may be agreed upon by the Parties, which

agreement the NYISO will not unreasonably withhold, condition, or delay if it determines a

longer cure period will not threaten the Developer’s ability to complete the Transmission Project by the Required Project In-Service Date; provided, however, that if the Breach is the result of a
Developer’s inability or failure to meet a Critical Path Milestone, the Developer may only cure
the Breach if either: (i) it meets the Critical Path Milestone within the cure period and
demonstrates to the NYISO’s satisfaction that, notwithstanding its failure to timely meet the
Critical Path Milestone, the Transmission Project will achieve its In-Service Date no later than
the Required Project In-Service Date, or (ii) the Developer requests in writing within the cure
period, and the NYISO consents to, a change to the missed Critical Path Milestone in accordance with Article 3.3.4.  If the Breach is cured within such timeframe, the Breach specified in the
notice shall cease to exist.  If the Breaching Party does not cure its Breach within this timeframe or cannot cure the Breach in a manner that provides for the Transmission Project to be completed by the Required Project In-Service Date, the non-Breaching Party shall have the right to declare a Default and terminate this Agreement pursuant to Article 8.1.

16

SERVICE AGREEMENT NO. 2510

7.3.Remedies

Upon the occurrence of an event of Default, the non-defaulting Party shall be entitled: (i)
to commence an action to require the defaulting Party to remedy such Default and specifically
perform its duties and obligations hereunder in accordance with the terms and conditions hereof;
and (ii) to exercise such other rights and remedies as it may have in equity or at law; provided,
however, the defaulting Party’s liability under this Agreement shall be limited to the extent set
forth in Article 9.1.  No remedy conferred by any provision of this Agreement is intended to be
exclusive of any other remedy and each and every remedy shall be cumulative and shall be in
addition to every other remedy given hereunder or now or hereafter existing at law or in equity
or by statute or otherwise.  The election of any one or more remedies shall not constitute a

waiver of the right to pursue other available remedies. This Article 7.3 shall survive the termination, expiration, or cancellation of this Agreement.

ARTICLE 8. TERMINATION

8.1.Termination by the NYISO

The NYISO may terminate this Agreement by providing written notice of termination to
the Developer in the event that: (i) the Developer notifies the NYISO that it is unable to or has
not received the required approvals or authorizations by Governmental Authorities required to
develop, construct, and operate the Transmission Project by the Required Project In-Service
Date; (ii) the Developer notifies the NYISO that its required approvals or authorizations by
Governmental Authorities have been withdrawn by the Governmental Authorities; (iii) the
Developer cannot complete the Transmission Project by the Required Project In-Service Date for
any reason: (A) including the occurrence of a Force Majeure event that will prevent the
Developer from completing the Transmission Project by the Required Project In-Service Date,
but (B) excluding a delay caused by a Connecting Transmission Owner or an Affected System
Operator; or (iv) the NYISO declares a default pursuant to Article 7.2 of this Agreement.

If the NYISO identifies grounds for termination under Articles 8.1(iii) or (iv) or receives
notice from the Developer under Articles 8.1(i) or (ii), the NYISO may, prior to providing a
written notice of termination, take action in accordance with Section 31.4.12.3.1.3 of Attachment
Y of the OATT to address the Public Policy Transmission Need and, notwithstanding the
confidentiality provisions in Article 11.2, may disclose information regarding the Transmission
Project to Governmental Authorities as needed to implement such action.  If the NYISO decides
to terminate this Agreement under Article 8.1(i), (ii), (iii), or (iv), it will provide written notice of
termination to the Developer, which notice will specify the date of termination.  If the
Agreement was filed and accepted by FERC pursuant to Section 31.4.12.2 of Attachment Y of
the OATT, the NYISO will, following its provision of a notice of termination to the Developer,
promptly file with FERC for its acceptance a notice of termination of this Agreement.

In the event of termination under Articles 8.1 (i) or (ii), the Developer may be eligible for
cost recovery under the OATT in the manner set forth in Attachment Y and Schedule 10 of the
OATT.  In the event of termination under Articles 8.1(iii) or (iv), cost recovery may be permitted
as determined by FERC.  In the event of termination for any reason under this Article 8.1, the
Developer shall use commercially reasonable efforts to mitigate the costs, damages, and charges

17

SERVICE AGREEMENT NO. 2510

arising as a consequence of termination and any transfer or winding up of the Transmission
Project.

8.2. Reporting of Inability to Comply with Provisions of Agreement

Notwithstanding the notification requirements in Article 3 and this Article 8 of this

Agreement, each Party shall notify the other Party promptly upon the notifying Party becoming aware of its inability to comply with any provision of this Agreement.  The Parties agree to
cooperate with each other and provide necessary information regarding such inability to comply, including the date, duration, reason for inability to comply, and corrective actions taken or
planned to be taken with respect to such inability to comply.

8.3. Transmission Project Transfer Rights Upon Termination

If the NYISO terminates this Agreement pursuant to Article 8.1, the NYISO shall have
the right, but shall not be required, to request an entity other than the Developer to complete the
Transmission Project.  The NYISO may exercise this right by providing the Developer with
written notice within sixty (60) days after the date on which this Agreement is terminated.  If the
NYISO exercises its right under this Article 8.3 and Section 31.4.12.3.1.3 of Attachment Y of
the OATT, the Developer shall work cooperatively with the NYISO’s designee pursuant to the
requirements set forth in Section 31.4.12.3.1.4 of Attachment Y of the OATT to implement the
transition, including entering into good faith negotiations with the NYISO’s designee to transfer
the Transmission Project to the NYISO’s designee.  All liabilities under this Agreement existing
prior to such transfer shall remain with the Developer, unless otherwise agreed upon by the
Developer and the NYISO’s designee as part of their good faith negotiations regarding the
transfer.  This Article 8.3 shall survive the termination, expiration, or cancellation of this
Agreement.

ARTICLE 9. LIABILITY AND INDEMNIFICATION

9.1.Liability

Notwithstanding any other provision in the NYISO’s tariffs and agreements to the

contrary, neither Party shall be liable, whether based on contract, indemnification, warranty,

equity, tort, strict liability, or otherwise, to the Other Party or any Transmission Owner, NYISO
Market Participant, third party or any other person for any damages whatsoever, including,
without limitation, direct, incidental, consequential (including, without limitation, attorneys’ fees
and litigation costs), punitive, special, multiple, exemplary, or indirect damages arising or
resulting from any act or omission under this Agreement, except in the event the Party is found
liable for gross negligence or intentional misconduct in the performance of its obligations under

actual damages.  This Article 9.1 shall survive the termination, expiration, or cancellation of this
Agreement.

18

SERVICE AGREEMENT NO. 2510

9.2.Indemnity

Notwithstanding any other provision in the NYISO’s tariffs and agreements to the
contrary, each Party shall at all times indemnify and save harmless, as applicable, the other

damages (including, without limitation, any consequential, incidental, direct, special, indirect,
exemplary or punitive damages and economic costs), losses, claims, including claims and actions
relating to injury to or death of any person or damage to property, liabilities, judgments,
demands, suits, recoveries, costs and expenses, court costs, attorney and expert fees, and all other
obligations by or to third parties, arising out of, or in any way resulting from this Agreement,
provided, however, that the Developer shall not have any indemnification obligation under this
Article 9.2 with respect to any loss to the extent the loss results from the gross negligence or
intentional misconduct of the NYISO; provided, further, that the NYISO shall only have an
indemnification obligation under this Article 9.2 with respect to any loss resulting from its gross
negligence or intentional misconduct to the same extent as provided in Section 2.11.3(b) of the
ISO OATT.  This Article 9.2 shall survive the termination, expiration, or cancellation of this
Agreement.

ARTICLE 10.ASSIGNMENT

This Agreement may be assigned by a Party only with the prior written consent of the other Party; provided that:

(i) any Change of Control shall be considered an assignment under this Article 10 and shall require the other Party’s prior written consent;

(ii) an assignment by the Developer shall be contingent upon the Developer or assignee demonstrating to the satisfaction of the NYISO prior to the effective date of the
assignment that: (A) the assignee has the technical competence, financial ability, and materials, equipment, and plans to comply with the requirements of this Agreement and to construct and place in service the Transmission Project by the Required Project InService Date consistent with the assignor’s cost estimates for the Transmission Project; and (B) the assignee satisfies the requirements for a qualified developer pursuant to
Section 31.4.4 of Attachment Y of the OATT; and

(iii) the Developer shall have the right to assign this Agreement, without the consent of

upon the exercise of the secured creditor’s, trustee’s, or mortgagee’s assignment rights
pursuant to said arrangement, the secured creditor, the trustee, or the mortgagee will
notify the NYISO of the date and particulars of any such exercise of assignment right(s),

Appendix A

Project Description

1.Transmission Project Overview

The transmission project is the New York Energy Solution Project (“Transmission

Project”) that was submitted by the Developer, evaluated as part of the NYISO’s Public Policy Transmission Planning Process, and selected by the NYISO Board of Directors on April 8, 2019 as the more efficient or cost-effective transmission solution to the need to increase the
UPNY/SENY transfer capability, which constitutes Segment B of the AC Transmission Public Policy Transmission Needs identified by the New York State Public Service Commission
(“NYPSC”) in its December 17, 2015 order in Case No. 12-T-0502.  The Transmission Project, as described below, contains modifications that the Developer requested to make on July 22,
2021, April 6, 2022, July 5, 2022, and August 5, 2022, and that the NYISO consented to in
accordance with Article 3.5 of the Agreement.

The Transmission Project will be mainly located in three counties (Rensselaer, Columbia and Dutchess) in the northern and mid-Hudson Valley, New York and will consist of the
components described in Sections 2 and 3 below.  The Transmission Project will be built entirely within existing transmission line corridors and property owned by the incumbent Transmission Owners, including National Grid.

2.Components of the Transmission Project

a. The Transmission Project consists of the following components:

•   A new 345 kV/115 kV double-circuit transmission line from a new Knickerbocker
switching station to the existing Pleasant Valley substation, and the rebuild of
approximately 2.1 miles of the 115 kV Blue Stores Tap;

•   A new 345 kV Knickerbocker switching station at the proposed, greenfield site in
Schodack, New York, which will house a two-step series compensator (33.3% and

16.67%) for the new 345 kV Knickerbocker to Pleasant Valley transmission line;

•   Rebuild of the existing NYSEG Churchtown 115 kV switching station in Claverack,
New York, which will require decommissioning of the existing facility; and

•   Two (2) new 135 MVAR 345 kV capacitor banks located in a new capacitor bank

station (“Van Wagner Capacitor Bank Station”) that will bifurcate the Athens to

Pleasant Valley 345 kV line (Line #91) and the Leeds to Pleasant Valley 345 kV Line (Line #92).

1

SERVICE AGREEMENT NO. 2510

The Transmission Project also includes additional upgrades to existing transmission
facilities as identified by the NYPSC in its December 17, 2015, order identifying the AC
Transmission Public Policy Transmission Needs—i.e., upgrades to the Rock Tavern 345 kV
substation and Coopers Corners substation and upgrades to the Shoemaker to Sugarloaf 138 kV facilities.  The Developer modified the upgrades identified by the NYPSC after performing
engineering and design work, and such upgrades are generally referred to as the “Rock Tavern to Sugarloaf component.”  Specifically, the Rock Tavern to Sugarloaf component contains the
following facilities and related work:

•   Terminal upgrades to the Rock Tavern 345 kV substation and Coopers Corners
substation;

•    Rebuild of the existing 115 kV Sugarloaf switching station, located in Chester, New
York, as a four-breaker ring bus substation with a 115 kV/138 kV autotransformer;

•   Replacement of an existing 12-mile overhead 115 kV transmission line with a new
115 kV transmission line, beginning at the existing 115 kV Rock Tavern substation,
located in New Windsor, New York, and terminating at the rebuilt 115 kV Sugarloaf
switching station; and

•   A new 138 kV transmission line beginning at the existing, rebuilt 115 kV Sugarloaf
switching station and terminating at the existing Orange and Rockland 138 kV
Sugarloaf switching station.; and

•   Terminal upgrades to the Orange and Rockland 138 kV Sugarloaf switching station to
accommodate the new 138 kV transmission line.

The Transmission Project has also been modified to include the installation of two (2)
phase angle regulators (“PARs”) on the Cricket Valley - Long Mountain 345 kV line (Line
#398), together with a spare PAR, that will be housed in a new substation to be located in
Dutchess County, New York.  The new substation will be located approximately 400 feet south
of Consolidated Edison Company of New York, Inc.’s right of way for its Line #398.  The PARs
and substation will be developed, constructed, and owned by the Developer.  The PARs are
required to address thermal degradation between the New York Control Area and New England,
which need was originally identified in the System Impact Study for the Transmission Project
pursuant to the NYISO’s Transmission Interconnection Procedures under Attachment P and was
common across the proposals to address Segment B of the AC Transmission Public Policy
Transmission Needs.

b. Network Upgrade Facilities:

The Transmission Project requires upgrades and expansions to existing transmission

facilities owned by Transmission Owners that will be identified as Network Upgrade Facilities and addressed in Transmission Project Interconnection Agreements or engineering, procurement, and construction agreements, as described below:

2

3.Interconnection Facilities

The Developer submitted an Interconnection Request for the Transmission Project to be
studied in the NYISO’s Transmission Interconnection Procedures under Attachment P to the
NYISO’s Open Access Transmission Tariff (“OATT”). The NYISO assigned the Transmission
Project Queue No. 543. The NYISO evaluated the impact of the Transmission Project on the
New York State Transmission System through Transmission Interconnection Studies.  These
studies determined that the interconnection and operation of the Transmission Project will

require the construction of certain Network Upgrade Facilities identified in the Facilities Study and include, but not be limited to, modifications to existing transmission facilities that the
Developer proposed as a component of the Transmission Project in the Public Policy
