Connecting Transmission Owner shall invoice Developer for such costs pursuant to

Article 12 and shall use due diligence to minimize its costs.  In the event Developer suspends

work by Connecting Transmission Owner required under this Agreement pursuant to this Article

5.16, and has not requested Connecting Transmission Owner to recommence the work required under this Agreement on or before the expiration of three (3) years following commencement of such suspension, this Agreement shall be deemed terminated.  The three-year period shall begin on the date the suspension is requested, or the date of the written notice to Connecting
Transmission Owner and NYISO, if no effective date is specified.

5.17Taxes.

5.17.1 Developer Payments Not Taxable.

The Developer and Connecting Transmission Owner intend that all payments or property transfers made by Developer to Connecting Transmission Owner for the installation of the
Connecting Transmission Owner’s Attachment Facilities and the System Upgrade Facilities and the System Deliverability Upgrades shall be non-taxable, either as contributions to capital, or as an advance, in accordance with the Internal Revenue Code and any applicable state income tax laws and shall not be taxable as contributions in aid of construction or otherwise under the
Internal Revenue Code and any applicable state income tax laws.

5.17.2 Representations and Covenants.

In accordance with IRS Notice 2001-82 and IRS Notice 88-129, Developer represents

and covenants that (i) ownership of the electricity generated at the Large Generating Facility will
pass to another party prior to the transmission of the electricity on the New York State
Transmission System, (ii) for income tax purposes, the amount of any payments and the cost of
any property transferred to the Connecting Transmission Owner for the Connecting
Transmission Owner’s Attachment Facilities will be capitalized by Developer as an intangible
asset and recovered using the straight-line method over a useful life of twenty (20) years, and

23

SERVICE AGREEMENT NO. 2593

(iii) any portion of the Connecting Transmission Owner’s Attachment Facilities that is a “dualuse intertie,” within the meaning of IRS Notice 88-129, is reasonably expected to carry only a de minimis amount of electricity in the direction of the Large Generating Facility.  For this purpose, “de minimis amount” means no more than 5 percent of the total power flows in both directions, calculated in accordance with the “5 percent test” set forth in IRS Notice 88-129.  This is not
intended to be an exclusive list of the relevant conditions that must be met to conform to IRS
requirements for non-taxable treatment.

At Connecting Transmission Owner’s request, Developer shall provide Connecting

Transmission Owner with a report from an independent engineer confirming its representation in clause (iii), above.  Connecting Transmission Owner represents and covenants that the cost of the Connecting Transmission Owner’s Attachment Facilities paid for by Developer will have no net effect on the base upon which rates are determined.

5.17.3 Indemnification for the Cost Consequences of Current Tax Liability Imposed
Upon the Connecting Transmission Owner.

Notwithstanding Article 5.17.1, Developer shall protect, indemnify and hold harmless

Connecting Transmission Owner from the cost consequences of any current tax liability imposed against Connecting Transmission Owner as the result of payments or property transfers made by Developer to Connecting Transmission Owner under this Agreement, as well as any interest and penalties, other than interest and penalties attributable to any delay caused by Connecting
Transmission Owner.

Connecting Transmission Owner shall not include a gross-up for the cost consequences
of any current tax liability in the amounts it charges Developer under this Agreement unless (i)
Connecting Transmission Owner has determined, in good faith, that the payments or property
transfers made by Developer to Connecting Transmission Owner should be reported as income
subject to taxation or (ii) any Governmental Authority directs Connecting Transmission Owner
to report payments or property as income subject to taxation; provided, however, that Connecting
Transmission Owner may require Developer to provide security, in a form reasonably acceptable
to Connecting Transmission Owner (such as a parental guarantee or a letter of credit), in an
amount equal to the cost consequences of any current tax liability under this Article 5.17.
Developer shall reimburse Connecting Transmission Owner for such costs on a fully grossed-up
basis, in accordance with Article 5.17.4, within thirty (30) Calendar Days of receiving written
notification from Connecting Transmission Owner of the amount due, including detail about how
the amount was calculated.

This indemnification obligation shall terminate at the earlier of (1) the expiration of the ten-year testing period and the applicable statute of limitation, as it may be extended by the Connecting Transmission Owner upon request of the IRS, to keep these years open for audit or adjustment, or (2) the occurrence of a subsequent taxable event and the payment of any related indemnification obligations as contemplated by this Article 5.17.

24

SERVICE AGREEMENT NO. 2593

5.17.4 Tax Gross-Up Amount.

Developer’s liability for the cost consequences of any current tax liability under this

Article 5.17 shall be calculated on a fully grossed-up basis.  Except as may otherwise be agreed
to by the parties, this means that Developer will pay Connecting Transmission Owner, in
addition to the amount paid for the Attachment Facilities and System Upgrade Facilities and
System Deliverability Upgrades, an amount equal to (1) the current taxes imposed on Connecting
Transmission Owner (“Current Taxes”) on the excess of (a) the gross income realized by
Connecting Transmission Owner as a result of payments or property transfers made by
Developer to Connecting Transmission Owner under this Agreement (without regard to any
payments under this Article 5.17) (the “Gross Income Amount”) over (b) the present value of
future tax deductions for depreciation that will be available as a result of such payments or
property transfers (the “Present Value Depreciation Amount”), plus (2) an additional amount
sufficient to permit the Connecting Transmission Owner to receive and retain, after the payment
of all Current Taxes, an amount equal to the net amount described in clause (1).

For this purpose, (i) Current Taxes shall be computed based on Connecting Transmission
Owner’s composite federal and state tax rates at the time the payments or property transfers are
received and Connecting Transmission Owner will be treated as being subject to tax at the
highest marginal rates in effect at that time (the “Current Tax Rate”), and (ii) the Present Value
Depreciation Amount shall be computed by discounting Connecting Transmission Owner’s
anticipated tax depreciation deductions as a result of such payments or property transfers by
Connecting Transmission Owner’s current weighted average cost of capital.  Thus, the formula
for calculating Developer’s liability to Connecting Transmission Owner pursuant to this Article

5.17.4 can be expressed as follows: (Current Tax Rate x (Gross Income Amount - Present Value Depreciation Amount))/(1 - Current Tax Rate).  Developer’s estimated tax liability in the event taxes are imposed shall be stated in Appendix A, Attachment Facilities and System Upgrade Facilities and System Deliverability Upgrades.

5.17.5 Private Letter Ruling or Change or Clarification of Law.

At Developer’s request and expense, Connecting Transmission Owner shall file with the
IRS a request for a private letter ruling as to whether any property transferred or sums paid, or to
be paid, by Developer to Connecting Transmission Owner under this Agreement are subject to
federal income taxation.  Developer will prepare the initial draft of the request for a private letter
ruling, and will certify under penalties of perjury that all facts represented in such request are
true and accurate to the best of Developer’s knowledge.  Connecting Transmission Owner and
Developer shall cooperate in good faith with respect to the submission of such request.

Connecting Transmission Owner shall keep Developer fully informed of the status of
such request for a private letter ruling and shall execute either a privacy act waiver or a limited
power of attorney, in a form acceptable to the IRS, that authorizes Developer to participate in all
discussions with the IRS regarding such request for a private letter ruling.  Connecting
Transmission Owner shall allow Developer to attend all meetings with IRS officials about the
request and shall permit Developer to prepare the initial drafts of any follow-up letters in
connection with the request.

25

SERVICE AGREEMENT NO. 2593

5.17.6 Subsequent Taxable Events.

If, within 10 years from the date on which the relevant Connecting Transmission Owner
Attachment Facilities are placed in service, (i) Developer Breaches the covenants contained in
Article 5.17.2, (ii) a “disqualification event” occurs within the meaning of IRS Notice 88-129, or
(iii) this Agreement terminates and Connecting Transmission Owner retains ownership of the
Attachment Facilities and System Upgrade Facilities and System Deliverability Upgrades, the
Developer shall pay a tax gross-up for the cost consequences of any current tax liability imposed
on Connecting Transmission Owner, calculated using the methodology described in Article

5.17.4 and in accordance with IRS Notice 90-60.

5.17.7 Contests.

In the event any Governmental Authority determines that Connecting Transmission

Owner’s receipt of payments or property constitutes income that is subject to taxation,

Connecting Transmission Owner shall notify Developer, in writing, within thirty (30) Calendar
Days of receiving notification of such determination by a Governmental Authority.  Upon the
timely written request by Developer and at Developer’s sole expense, Connecting Transmission
Owner may appeal, protest, seek abatement of, or otherwise oppose such determination.  Upon
Developer’s written request and sole expense, Connecting Transmission Owner may file a claim
for refund with respect to any taxes paid under this Article 5.17, whether or not it has received
such a determination.  Connecting Transmission Owner reserves the right to make all decisions
with regard to the prosecution of such appeal, protest, abatement or other contest, including the
selection of counsel and compromise or settlement of the claim, but Connecting Transmission
Owner shall keep Developer informed, shall consider in good faith suggestions from Developer
about the conduct of the contest, and shall reasonably permit Developer or an Developer

representative to attend contest proceedings.

Developer shall pay to Connecting Transmission Owner on a periodic basis, as invoiced
by Connecting Transmission Owner, Connecting Transmission Owner’s documented reasonable
costs of prosecuting such appeal, protest, abatement or other contest, including any costs
associated with obtaining the opinion of independent tax counsel described in this Article 5.17.7.
The Connecting Transmission Owner may abandon any contest if the Developer fails to provide
payment to the Connecting Transmission Owner within thirty (30) Calendar Days of receiving
such invoice.  At any time during the contest, Connecting Transmission Owner may agree to a
settlement either with Developer’s consent or after obtaining written advice from nationally-
recognized tax counsel, selected by Connecting Transmission Owner, but reasonably acceptable
to Developer, that the proposed settlement represents a reasonable settlement given the hazards
of litigation.  Developer’s obligation shall be based on the amount of the settlement agreed to by
Developer, or if a higher amount, so much of the settlement that is supported by the written
advice from nationally-recognized tax counsel selected under the terms of the preceding
sentence.  The settlement amount shall be calculated on a fully grossed-up basis to cover any
related cost consequences of the current tax liability.  The Connecting Transmission Owner may
also settle any tax controversy without receiving the Developer’s consent or any such written
advice; however, any such settlement will relieve the Developer from any obligation to

26

SERVICE AGREEMENT NO. 2593

indemnify Connecting Transmission Owner for the tax at issue in the contest (unless the failure to obtain written advice is attributable to the Developer’s unreasonable refusal to the
appointment of independent tax counsel).

5.17.8 Refund.

In the event that (a) a private letter ruling is issued to Connecting Transmission Owner
which holds that any amount paid or the value of any property transferred by Developer to
Connecting Transmission Owner under the terms of this Agreement is not subject to federal
income taxation, (b) any legislative change or administrative announcement, notice, ruling or
other determination makes it reasonably clear to Connecting Transmission Owner in good faith
that any amount paid or the value of any property transferred by Developer to Connecting
Transmission Owner under the terms of this Agreement is not taxable to Connecting
Transmission Owner, (c) any abatement, appeal, protest, or other contest results in a
determination that any payments or transfers made by Developer to Connecting Transmission
Owner are not subject to federal income tax, or (d) if Connecting Transmission Owner receives a
refund from any taxing authority for any overpayment of tax attributable to any payment or
property transfer made by Developer to Connecting Transmission Owner pursuant to this
Agreement, Connecting Transmission Owner shall promptly refund to Developer the following:

(i) Any payment made by Developer under this Article 5.17 for taxes that is
attributable to the amount determined to be non-taxable, together with interest thereon,

(ii) Interest on any amounts paid by Developer to Connecting Transmission Owner for such taxes which Connecting Transmission Owner did not submit to the taxing authority, calculated in accordance with the methodology set forth in FERC’s regulations at 18 C.F.R. §35.19a(a)(2)(iii) from the date payment was made by Developer to the date Connecting
Transmission Owner refunds such payment to Developer, and

(iii) With respect to any such taxes paid by Connecting Transmission Owner, any
refund or credit Connecting Transmission Owner receives or to which it may be entitled from
any Governmental Authority, interest (or that portion thereof attributable to the payment
described in clause (i), above) owed to the Connecting Transmission Owner for such
overpayment of taxes (including any reduction in interest otherwise payable by Connecting
Transmission Owner to any Governmental Authority resulting from an offset or credit);
provided, however, that Connecting Transmission Owner will remit such amount promptly to
Developer only after and to the extent that Connecting Transmission Owner has received a tax
refund, credit or offset from any Governmental Authority for any applicable overpayment of
income tax related to the Connecting Transmission Owner’s Attachment Facilities.

The intent of this provision is to leave both the Developer and Connecting Transmission
Owner, to the extent practicable, in the event that no taxes are due with respect to any payment
for Attachment Facilities and System Upgrade Facilities and System Deliverability Upgrades
hereunder, in the same position they would have been in had no such tax payments been made.

27

SERVICE AGREEMENT NO. 2593

5.17.9 Taxes Other Than Income Taxes.

Upon the timely request by Developer, and at Developer’s sole expense, Connecting

Transmission Owner shall appeal, protest, seek abatement of, or otherwise contest any tax (other
than federal or state income tax) asserted or assessed against Connecting Transmission Owner
for which Developer may be required to reimburse Connecting Transmission Owner under the
terms of this Agreement.  Developer shall pay to Connecting Transmission Owner on a periodic
basis, as invoiced by Connecting Transmission Owner, Connecting Transmission Owner’s
documented reasonable costs of prosecuting such appeal, protest, abatement, or other contest.
Developer and Connecting Transmission Owner shall cooperate in good faith with respect to any
such contest.  Unless the payment of such taxes is a prerequisite to an appeal or abatement or
cannot be deferred, no amount shall be payable by Developer to Connecting Transmission
Owner for such taxes until they are assessed by a final, non-appealable order by any court or
agency of competent jurisdiction.  In the event that a tax payment is withheld and ultimately due
and payable after appeal, Developer will be responsible for all taxes, interest and penalties, other
than penalties attributable to any delay caused by Connecting Transmission Owner.

5.18Tax Status; Non-Jurisdictional Entities.

5.18.1 Tax Status.

33

SERVICE AGREEMENT NO. 2593

9.5Real and Reactive Power Control and Primary Frequency Response.

9.5.1   Power Factor Design Criteria.

9.5.1.1  Synchronous Generation.  Developer shall design the Large Generating Facility
to maintain effective composite power delivery at continuous rated power output at the Point of
Interconnection at a power factor within the range of 0.95 leading to 0.95 lagging unless the
NYISO or the Transmission Owner in whose Transmission District the Large Generating Facility
interconnects has established different requirements that apply to all generators in the New York
Control Area or Transmission District (as applicable) on a comparable basis, in accordance with
Good Utility Practice.

The Developer shall design and maintain the plant auxiliary systems to operate safely throughout the entire real and reactive power design range.

9.5.1.2  Non-Synchronous Generation.  Developer shall design the Large Generating
Facility to maintain composite power delivery at continuous rated power output at the high-side of the generator substation at a power factor within the range of 0.95 leading to 0.95 lagging,
unless the NYISO or the Transmission Owner in whose Transmission District the Large
Generating Facility interconnects has established a different power factor range that applies to all non-synchronous generators in the Control Area or Transmission District (as applicable) on a
comparable basis, in accordance with Good Utility Practice.   This power factor range standard
shall be dynamic and can be met using, for example, power electronics designed to supply this
level of reactive capability (taking into account any limitations due to voltage level, real power
output, etc.) or fixed and switched capacitors, or a combination of the two.  This requirement
shall only apply to newly interconnection non-synchronous generators that have not yet executed a Facilities Study Agreement as of September 21, 2016.

The Developer shall design and maintain the plant auxiliary systems to operate safely throughout the entire real and reactive power design range.

9.5.2   Voltage Schedules.

Once the Developer has synchronized the Large Generating Facility with the New York
State Transmission System, NYISO shall require Developer to operate the Large Generating
Facility to produce or absorb reactive power within the design capability of the Large Generating
Facility set forth in Article 9.5.1 (Power Factor Design Criteria).  NYISO’s voltage schedules
shall treat all sources of reactive power in the New York Control Area in an equitable and not
unduly discriminatory manner.  NYISO shall exercise Reasonable Efforts to provide Developer
with such schedules in accordance with NYISO procedures, and may make changes to such
schedules as necessary to maintain the reliability of the New York State Transmission System.
Developer shall operate the Large Generating Facility to maintain the specified output voltage or
power factor at the Point of Interconnection within the design capability of the Large Generating
Facility set forth in Article 9.5.1 (Power Factor Design Criteria) as directed by the Connecting
Transmission Owner’s system operator or the NYISO.  If Developer is unable to maintain the
specified voltage or power factor, it shall promptly notify NYISO.

34

SERVICE AGREEMENT NO. 2593

9.5.3   Payment for Reactive Power.

NYISO shall pay Developer for reactive power or voltage support service that Developer
provides from the Large Generating Facility in accordance with the provisions of Rate Schedule

2 of the NYISO Services Tariff.

9.5.4   Voltage Regulators.

Whenever the Large Generating Facility is operated in parallel with the New York State
Transmission System, the automatic voltage regulators shall be in automatic operation at all
times.  If the Large Generating Facility’s automatic voltage regulators are not capable of such
automatic operation, the Developer shall immediately notify NYISO, or its designated
representative, and ensure that such Large Generating Facility’s real and reactive power are
within the design capability of the Large Generating Facility’s generating unit(s) and steady state
stability limits and NYISO system operating (thermal, voltage and transient stability) limits.
Developer shall not cause its Large Generating Facility to disconnect automatically or
instantaneously from the New York State Transmission System or trip any generating unit
comprising the Large Generating Facility for an under or over frequency condition unless the
abnormal frequency condition persists for a time period beyond the limits set forth in
ANSI/IEEE Standard C37.106, or such other standard as applied to other generators in the New
York Control Area on a comparable basis.

9.5.5   Primary Frequency Response.

Developer shall ensure the primary frequency response capability of its Large Generating
Facility by installing, maintaining, and operating a functioning governor or equivalent controls.
The term “functioning governor or equivalent controls” as used herein shall mean the required
hardware and/or software that provides frequency responsive real power control with the ability
to sense changes in system frequency and autonomously adjust the Large Generating Facility’s
real power output in accordance with the droop and deadband parameters and in the direction

needed to correct frequency deviations.  Developer is required to install a governor or equivalent
controls with the capability of operating: (1) with a maximum 5 percent droop ± 0.036 Hz
deadband; or (2) in accordance with the relevant droop, deadband, and timely and sustained
response settings from an approved Applicable Reliability Standard providing for equivalent or
more stringent parameters.  The droop characteristic shall be: (1) based on the nameplate
capacity of the Large Generating Facility, and shall be linear in the range of frequencies between

59 and 61 Hz that are outside of the deadband parameter; or (2) based on an approved Applicable
Reliability Standard providing for an equivalent or more stringent parameter.  The deadband
parameter shall be: the range of frequencies above and below nominal (60 Hz) in which the
governor or equivalent controls is not expected to adjust the Large Generating Facility’s real
power output in response to frequency deviations.  The deadband shall be implemented: (1)
without a step to the droop curve, that is, once the frequency deviation exceeds the deadband
parameter, the expected change in the Large Generating Facility’s real power output in response
to frequency deviations shall start from zero and then increase (for under-frequency deviations)
or decrease (for over-frequency deviations) linearly in proportion to the magnitude of the

35

SERVICE AGREEMENT NO. 2593

frequency deviation; or (2) in accordance with an approved Applicable Reliability Standard

providing for an equivalent or more stringent parameter.  Developer shall notify NYISO that the primary frequency response capability of the Large Generating Facility has been tested and
confirmed during commissioning.  Once Developer has synchronized the Large Generating
Facility with the New York State Transmission System, Developer shall operate the Large
Generating Facility consistent with the provisions specified in Articles 9.5.5.1 and 9.5.5.2 of this Agreement.  The primary frequency response requirements contained herein shall apply to both synchronous and non-synchronous Large Generating Facilities.

9.5.5.1 Governor or Equivalent Controls.

Whenever the Large Generating Facility is operated in parallel with the New York State
Transmission System, Developer shall operate the Large Generating Facility with its governor or
equivalent controls in service and responsive to frequency.  Developer shall: (1) in coordination
with NYISO, set the deadband parameter to: (1) a maximum of ±0.036 Hz and set the droop
parameter to a maximum of 5 percent; or (2) implement the relevant droop and deadband settings
from an approved Applicable Reliability Standard that provides for equivalent or more stringent
parameters.  Developer shall be required to provide the status and settings of the governor and
equivalent controls to NYISO and/or the Connecting Transmission Owner upon request.  If
Developer needs to operate the Large Generating Facility with its governor or equivalent
controls not in service, Developer shall immediately notify NYISO and the Connecting
Transmission Owner, and provide both with the following information: (1) the operating status
of the governor or equivalent controls (i.e., whether it is currently out of service or when it will
be taken out of service); (2) the reasons for removing the governor or equivalent controls from
service; and (3) a reasonable estimate of when the governor or equivalent controls will be
returned to service.  Developer shall make Reasonable Efforts to return its governor or
equivalent controls into service as soon as practicable.  Developer shall make Reasonable Efforts
to keep outages of the Large Generating Facility’s governor or equivalent controls to a minimum
whenever the Large Generating Facility is operated in parallel with the New York State
Transmission System.

9.5.5.2 Timely and Sustained Response.

Developer shall ensure that the Large Generating Facility’s real power response to

sustained frequency deviations outside of the deadband setting is automatically provided and
shall begin immediately after frequency deviates outside of the deadband, and to the extent the
Large Generating Facility has operating capability in the direction needed to correct the
frequency deviation.  Developer shall not block or otherwise inhibit the ability of the governor or
equivalent controls to respond and shall ensure that the response is not inhibited, except under
certain operational constraints including, but not limited to, ambient temperature limitations,
physical energy limitations, outages of mechanical equipment, or regulatory requirements.  The
Large Generating Facility shall sustain the real power response at least until system frequency
returns to a value within the deadband setting of the governor or equivalent controls.  An
Applicable Reliability Standard with equivalent or more stringent requirements shall supersede
the above requirements.

9.5.5.3 Exemptions.

36

SERVICE AGREEMENT NO. 2593

Large Generating Facilities that are regulated by the United States Nuclear Regulatory Commission shall be exempt from Articles 9.5.5, 9.5.5.1, and 9.5.5.2 of this Agreement.  Large Generating Facilities that are behind the meter generation that is sized-to-load (i.e., the thermal load and the generation are near-balanced in real-time operation and the generation is primarily controlled to maintain the unique thermal, chemical, or mechanical output necessary for the
operating requirements of its host facility) shall be required to install primary frequency response capability requirements in accordance with the droop and deadband capability requirements
specified in Article 9.5.5, but shall be otherwise exempt from the operating requirements in
Articles 9.5.5, 9.5.5.1, 9.5.5.2, and 9.5.5.4 of this Agreement.

9.5.5.4 Electric Storage Resources.

Developer interconnecting an electric storage resource shall establish an operating range
in Appendix C of its LGIA that specifies a minimum state of charge and a maximum state of
charge between which the electric storage resource will be required to provide primary frequency
response consistent with the conditions set forth in Articles 9.5.5, 9.5.5.1, 9.5.5.2, and 9.5.5.3 of
this Agreement.  Appendix C shall specify whether the operating range is static or dynamic, and
shall consider (1) the expected magnitude of frequency deviations in the interconnection; (2) the
expected duration that system frequency will remain outside of the deadband parameter in the
interconnection; (3) the expected incidence of frequency deviations outside of the deadband
parameter in the interconnection; (4) the physical capabilities of the electric storage resource; (5)
operational limitations of the electric storage resources due to manufacturer specification; and (6)
any other relevant factors agreed to by the NYISO, Connecting Transmission Owner, and
Developer.  If the operating range is dynamic, then Appendix C must establish how frequently
the operating range will be reevaluated and the factors that may be considered during its
reevaluation.

Developer’s electric storage resource is required to provide timely and sustained primary
frequency response consistent with Article 9.5.5.2 of this Agreement when it is online and
dispatched to inject electricity to the New York State Transmission System and/or receive
electricity from the New York State Transmission System.  This excludes circumstances when
the electric storage resource is not dispatched to inject electricity to the New York State
Transmission System and/or dispatched to receive electricity from the New York State
Transmission System.  If Developer’s electric storage resource is charging at the time of a
frequency deviation outside of its deadband parameter, it is to increase (for over-frequency
deviations) or decrease (for under-frequency deviations) the rate at which it is charging in
accordance with its droop parameter.  Developer’s electric storage resource is not required to
change from charging to discharging, or vice versa, unless the response necessitated by the droop
and deadband settings requires it to do so and it is technically capable of making such a
transition.

9.6Outages and Interruptions.

9.6.1Outages.

9.6.1.1 Outage Authority and Coordination.

37

and sequence of events records, and any disturbance information required by Good Utility
Practice.

9.10Phasor Measurement Units

A Developer shall install and maintain, at its expense, phasor measurement units

(“PMUs”) if it meets the following criteria:  (1) completed a Class Year after Class Year 2017; and (2) proposes a new Large Facility that either (a) has a maximum net output equal to or greater than 100 MW or (b) requires, as Attachment Facilities or System Upgrade Facilities, a new substation of 230kV or above.

PMUs shall be installed on the Large Facility on the low side of the generator step-up

transformer, unless it is a non-synchronous generation facility, in which case the PMUs shall be installed on the Developer side of the Point of Interconnection.  The PMUs must be capable of
performing phasor measurements at a minimum of 60 samples per second which are
synchronized via a high-accuracy satellite clock. To the extent Developer installs similar quality equipment, such as relays or digital fault recorders, that can collect data at least at the same rate as PMUs and which data is synchronized via a high-accuracy satellite clock, such equipment
would satisfy this requirement.

Developer shall be required to install and maintain, at its expense, PMU equipment which
includes the communication circuit capable of carrying the PMU data to a local data
concentrator, and then transporting the information continuously to the Connecting Transmission
Owner and the NYISO; as well as store the PMU data locally for thirty days. Developer shall
provide to Connecting Transmission Owner and the NYISO all necessary and requested
information through the Connecting Transmission Owner’s and the NYISO’s synchrophasor
system, including the following: (a) gross MW and MVAR measured at the Developer side of
the generator step-up transformer (or, for a non-synchronous generation facility, to be measured
at the Developer side of the Point of Interconnection); (b) generator terminal voltage and current
magnitudes and angles; (c) generator terminal frequency and frequency rate of change; and

(d) generator field voltage and current, where available; and (e) breaker status, if available. The
Connecting Transmission Owner will provide for the ongoing support and maintenance of the
network communications linking the data concentrator to the Connecting Transmission Owner
and the NYISO, consistent with ISO Procedures detailing the obligations related to SCADA
data.

restoration of service.

NYISO and Connecting Transmission Owner shall use Reasonable Efforts to minimize
the effect of such actions or inactions on the Large Generating Facility or the Developer’s
Attachment Facilities.  NYISO or Connecting Transmission Owner may, on the basis of
technical considerations, require the Large Generating Facility to mitigate an Emergency State
by taking actions necessary and limited in scope to remedy the Emergency State, including, but
not limited to, directing Developer to shut-down, start-up, increase or decrease the real or
reactive power output of the Large Generating Facility; implementing a reduction or
disconnection pursuant to Article 13.4.2; directing the Developer to assist with blackstart (if
available) or restoration efforts; or altering the outage schedules of the Large Generating Facility and the Developer’s Attachment Facilities.  Developer shall comply with all of the NYISO and
Connecting Transmission Owner’s operating instructions concerning Large Generating Facility
real power and reactive power output within the manufacturer’s design limitations of the Large
Generating Facility’s equipment that is in service and physically available for operation at the
time, in compliance with Applicable Laws and Regulations.

13.4.2 Reduction and Disconnection.

NYISO or Connecting Transmission Owner may reduce Energy Resource

Interconnection Service and Capacity Resource Interconnection Service or disconnect the Large
Generating Facility or the Developer’s Attachment Facilities, when such reduction or
disconnection is necessary under Good Utility Practice due to an Emergency State.  These rights
are separate and distinct from any right of Curtailment of NYISO pursuant to the ISO OATT.
When NYISO or Connecting Transmission Owner can schedule the reduction or disconnection
in advance, NYISO or Connecting Transmission Owner shall notify Developer of the reasons,

47

SERVICE AGREEMENT NO. 2593

timing and expected duration of the reduction or disconnection.  NYISO or Connecting

Transmission Owner shall coordinate with the Developer using Good Utility Practice to schedule
the reduction or disconnection during periods of least impact to the Developer and the New York
State Transmission System.  Any reduction or disconnection shall continue only for so long as
reasonably necessary under Good Utility Practice.  The Parties shall cooperate with each other to
restore the Large Generating Facility, the Attachment Facilities, and the New York State
Transmission System to their normal operating state as soon as practicable consistent with Good
Utility Practice.

13.5Developer Authority.

Consistent with Good Utility Practice and this Agreement, the Developer may take

whatever actions or inactions with regard to the Large Generating Facility or the Developer’s

Attachment Facilities during an Emergency State in order to (i) preserve public health and safety,
(ii) preserve the reliability of the Large Generating Facility or the Developer’s Attachment
Facilities, (iii) limit or prevent damage, and (iv) expedite restoration of service.  Developer shall
use Reasonable Efforts to minimize the effect of such actions or inactions on the New York State
Transmission System and the Connecting Transmission Owner’s Attachment Facilities.  NYISO
and Connecting Transmission Owner shall use Reasonable Efforts to assist Developer in such
actions.

13.6Limited Liability.

Except as otherwise provided in Article 11.6 of this Agreement, no Party shall be liable
to another Party for any action it takes in responding to an Emergency State so long as such
action is made in good faith and is consistent with Good Utility Practice and the NYISO Tariffs.

The provisions of this Article will survive termination of this Agreement.

ARTICLE 18. INDEMNITY, CONSEQUENTIAL DAMAGES AND INSURANCE

18.1Indemnity.

Each Party (the “Indemnifying Party”) shall at all times indemnify, defend, and save

harmless, as applicable, the other Parties (each an “Indemnified Party”) from, any and all

or damage to property, the alleged violation of any Environmental Law, or the release or
threatened release of any Hazardous Substance, demand, suits, recoveries, costs and expenses,
court costs, attorney fees, and all other obligations by or to third parties (any and all of these a
“Loss”), arising out of or resulting from (i) the Indemnified Party’s performance of its
obligations under this Agreement on behalf of the Indemnifying Party, except in cases where the
Indemnifying Party can demonstrate that the Loss of the Indemnified Party was caused by the
gross negligence or intentional wrongdoing of the Indemnified Party or (ii) the violation by the
Indemnifying Party of any Environmental Law or the release by the Indemnifying Party of any
Hazardous Substance.

50

SERVICE AGREEMENT NO. 2593

18.1.1Indemnified Party.

If a Party is entitled to indemnification under this Article 18 as a result of a claim by a third party, and the Indemnifying Party fails, after notice and reasonable opportunity to proceed under Article 18.1.3, to assume the defense of such claim, such Indemnified Party may at the expense of the Indemnifying Party contest, settle or consent to the entry of any judgment with respect to, or pay in full, such claim.

18.1.2Indemnifying Party.

If an Indemnifying Party is obligated to indemnify and hold any Indemnified Party

harmless under this Article 18, the amount owing to the Indemnified Party shall be the amount of such Indemnified Party’s actual Loss, net of any insurance or other recovery.

18.1.3Indemnity Procedures.

Promptly after receipt by an Indemnified Party of any claim or notice of the

commencement of any action or administrative or legal proceeding or investigation as to which
the indemnity provided for in Article 18.1 may apply, the Indemnified Party shall notify the
Indemnifying Party of such fact.  Any failure of or delay in such notification shall not affect a
Party’s indemnification obligation unless such failure or delay is materially prejudicial to the
Indemnifying Party.

Except as stated below, the Indemnifying Party shall have the right to assume the defense
thereof with counsel designated by such Indemnifying Party and reasonably satisfactory to the
Indemnified Party.  If the defendants in any such action include one or more Indemnified Parties
and the Indemnifying Party and if the Indemnified Party reasonably concludes that there may be
legal defenses available to it and/or other Indemnified Parties which are different from or
additional to those available to the Indemnifying Party, the Indemnified Party shall have the right
to select separate counsel to assert such legal defenses and to otherwise participate in the defense
of such action on its own behalf.  In such instances, the Indemnifying Party shall only be
required to pay the fees and expenses of one additional attorney to represent an Indemnified
Party or Indemnified Parties having such differing or additional legal defenses.

The Indemnified Party shall be entitled, at its expense, to participate in any such action,
suit or proceeding, the defense of which has been assumed by the Indemnifying Party.
Notwithstanding the foregoing, the Indemnifying Party (i) shall not be entitled to assume and
control the defense of any such action, suit or proceedings if and to the extent that, in the opinion
of the Indemnified Party and its counsel, such action, suit or proceeding involves the potential
imposition of criminal liability on the Indemnified Party, or there exists a conflict or adversity of
interest between the Indemnified Party and the Indemnifying Party, in such event the
Indemnifying Party shall pay the reasonable expenses of the Indemnified Party, and (ii) shall not
settle or consent to the entry of any judgment in any action, suit or proceeding without the
consent of the Indemnified Party, which shall not be unreasonably withheld, conditioned or
delayed.

51

SERVICE AGREEMENT NO. 2593

18.2No Consequential Damages.

Other than the liquidated damages heretofore described and the indemnity obligations set
forth in Article 18.1, in no event shall any Party be liable under any provision of this Agreement

punitive damages, including but not limited to loss of profit or revenue, loss of the use of
equipment, cost of capital, cost of temporary equipment or services, whether based in whole or in
part in contract, in tort, including negligence, strict liability, or any other theory of liability;

18.3.11 Within sixty (60) days following execution of this Agreement, and as soon

as practicable after the end of each fiscal year or at the renewal of the insurance policy and in
any event within ninety (90) days thereafter, Developer and Connecting Transmission Owner

53

SERVICE AGREEMENT NO. 2593

shall provide certificate of insurance for all insurance required in this Agreement, executed by each insurer or by an authorized representative of each insurer.

18.3.12 Notwithstanding the foregoing, Developer and Connecting Transmission

the other Party that it meets the requirements to self-insure and that its self-insurance program
meets the minimum insurance requirements in a manner consistent with that specified in Articles

18.3.1 through 18.3.9 and provide evidence of such coverages.  For any period of time that a Party’s senior debt is unrated by Standard & Poor’s or is rated at less than investment grade by Standard & Poor’s, such Party shall comply with the insurance requirements applicable to it under Articles 18.3.1 through 18.3.9.

Parties; provided that a Party may assign this Agreement without the consent of the other Parties
to any Affiliate of the assigning Party with an equal or greater credit rating and with the legal
authority and operational ability to satisfy the obligations of the assigning Party under this
Agreement; provided further that a Party may assign this Agreement without the consent of the
other Parties in connection with the sale, merger, restructuring, or transfer of a substantial
portion or all of its assets, including the Attachment Facilities it owns, so long as the assignee in
such a transaction directly assumes in writing all rights, duties and obligations arising under this
Agreement; and provided further that the Developer shall have the right to assign this
Agreement, without the consent of the NYISO or Connecting Transmission Owner, for collateral
security purposes to aid in providing financing for the Large Generating Facility, provided that
the Developer will promptly notify the NYISO and Connecting Transmission Owner of any such
assignment.  Any financing arrangement entered into by the Developer pursuant to this Article
will provide that prior to or upon the exercise of the secured party’s, trustee’s or mortgagee’s
assignment rights pursuant to said arrangement, the secured creditor, the trustee or mortgagee
will notify the NYISO and Connecting Transmission Owner of the date and particulars of any
such exercise of assignment right(s) and will provide the NYISO and Connecting Transmission
Owner with proof that it meets the requirements of Articles 11.5 and 18.3.  Any attempted

54

SERVICE AGREEMENT NO. 2593

unreasonably withheld, conditioned or delayed.

ARTICLE 20. SEVERABILITY

If any provision in this Agreement is finally determined to be invalid, void or

unenforceable by any court or other Governmental Authority having jurisdiction, such

third party is not acting at the direction of the Connecting Transmission Owner) seeks and
obtains such a final determination with respect to any provision of the Alternate Option (Article

5.1.2), or the Negotiated Option (Article 5.1.4), then none of these provisions shall thereafter have any force or effect and the rights and obligations of Developer and Connecting
Transmission Owner shall be governed solely by the Standard Option (Article 5.1.1).

ARTICLE 21. COMPARABILITY

The Parties will comply with all applicable comparability and code of conduct laws, rules and regulations, as amended from time to time.

receiving Party; (2) was in the lawful possession of the receiving Party on a non-confidential
basis before receiving it from the disclosing Party; (3) was supplied to the receiving Party

(4) was independently developed by the receiving Party without reference to Confidential

Information of the disclosing Party; (5) is, or becomes, publicly known, through no wrongful act
or omission of the receiving Party or Breach of this Agreement; or (6) is required, in accordance
with Article 22.9 of this Agreement, Order of Disclosure, to be disclosed by any Governmental
Authority or is otherwise required to be disclosed by law or subpoena, or is necessary in any
legal proceeding establishing rights and obligations under this Agreement.  Information
designated as Confidential Information will no longer be deemed confidential if the Party that
designated the information as confidential notifies the other Party that it no longer is
confidential.

22.5Release of Confidential Information.

No Party shall release or disclose Confidential Information to any other person, except to
its Affiliates (limited by FERC Standards of Conduct requirements), subcontractors, employees,
consultants, or to parties who may be considering providing financing to or equity participation
with Developer, or to potential purchasers or assignees of a Party, on a need-to-know basis in
connection with this Agreement, unless such person has first been advised of the confidentiality
provisions of this Article 22 and has agreed to comply with such provisions.  Notwithstanding
the foregoing, a Party providing Confidential Information to any person shall remain primarily
responsible for any release of Confidential Information in contravention of this Article 22.

22.6Rights.

Each Party retains all rights, title, and interest in the Confidential Information that each Party discloses to the other Party.  The disclosure by each Party to the other Parties of
Confidential Information shall not be deemed a waiver by any Party or any other person or entity of the right to protect the Confidential Information from public disclosure.

22.7No Warranties.

By providing Confidential Information, no Party makes any warranties or representations
as to its accuracy or completeness.  In addition, by supplying Confidential Information, no Party

56

SERVICE AGREEMENT NO. 2593

22.8Standard of Care.

Each Party shall use at least the same standard of care to protect Confidential Information it receives as it uses to protect its own Confidential Information from unauthorized disclosure, publication or dissemination.  Each Party may use Confidential Information solely to fulfill its obligations to the other Parties under this Agreement or its regulatory requirements, including the ISO OATT and NYISO Services Tariff.  The NYISO shall, in all cases, treat the information it receives in accordance with the requirements of Attachment F to the ISO OATT.

22.9Order of Disclosure.

If a court or a Government Authority or entity with the right, power, and apparent

authority to do so requests or requires any Party, by subpoena, oral deposition, interrogatories,

requests for production of documents, administrative order, or otherwise, to disclose Confidential
Information, that Party shall provide the other Parties with prompt notice of such request(s) or
requirement(s) so that the other Parties may seek an appropriate protective order or waive
compliance with the terms of this Agreement.  Notwithstanding the absence of a protective order
or waiver, the Party may disclose such Confidential Information which, in the opinion of its
counsel, the Party is legally compelled to disclose.  Each Party will use Reasonable Efforts to
obtain reliable assurance that confidential treatment will be accorded any Confidential
Information so furnished.

22.10Termination of Agreement.

Upon termination of this Agreement for any reason, each Party shall, within ten (10)
Calendar Days of receipt of a written request from the other Parties, use Reasonable Efforts to

other Parties) or return to the other Parties, without retaining copies thereof, any and all written
or electronic Confidential Information received from the other Parties pursuant to this
Agreement.

22.11Remedies.

The Parties agree that monetary damages would be inadequate to compensate a Party for
another Party’s Breach of its obligations under this Article 22.  Each Party accordingly agrees
that the other Parties shall be entitled to equitable relief, by way of injunction or otherwise, if the
first Party Breaches or threatens to Breach its obligations under this Article 22, which equitable
relief shall be granted without bond or proof of damages, and the receiving Party shall not plead
in defense that there would be an adequate remedy at law.  Such remedy shall not be deemed an
exclusive remedy for the Breach of this Article 22, but shall be in addition to all other remedies
available at law or in equity.  The Parties further acknowledge and agree that the covenants

contained herein are necessary for the protection of legitimate business interests and are

reasonable in scope.  No Party, however, shall be liable for indirect, incidental, or consequential
or punitive damages of any nature or kind resulting from or arising in connection with this
Article 22.

57

SERVICE AGREEMENT NO. 2593

22.12Disclosure to FERC, its Staff, or a State.

Notwithstanding anything in this Article 22 to the contrary, and pursuant to 18 C.F.R.
section 1b.20, if FERC or its staff, during the course of an investigation or otherwise, requests
information from one of the Parties that is otherwise required to be maintained in confidence
pursuant to this Agreement or the ISO OATT, the Party shall provide the requested information
to FERC or its staff, within the time provided for in the request for information.  In providing the

notified by FERC or its staff that a request to release Confidential Information has been received
by FERC, at which time the Parties may respond before such information would be made public,
pursuant to 18 C.F.R. section 388.112.  Requests from a state regulatory body conducting a
confidential investigation shall be treated in a similar manner if consistent with the applicable
state rules and regulations.  A Party shall not be liable for any losses, consequential or otherwise,
resulting from that Party divulging Confidential Information pursuant to a FERC or state
regulatory body request under this paragraph.

disclosing Party to be required to be disclosed in connection with a dispute between or among
the Parties, or the defense of litigation or dispute; (iii) otherwise permitted by consent of the
other Party, such consent not to be unreasonably withheld; or (iv) necessary to fulfill its
obligations under this Agreement, the ISO OATT or the NYISO Services Tariff.  Prior to any
disclosures of a Party’s Confidential Information under this subparagraph, or if any third party or
Governmental Authority makes any request or demand for any of the information described in
this subparagraph, the disclosing Party agrees to promptly notify the other Party in writing and
agrees to assert confidentiality and cooperate with the other Party in seeking to protect the

Connecting Transmission Owner shall provide Developer and NYISO a status report on the
construction and installation of Connecting Transmission Owner’s Attachment Facilities and
System Upgrade Facilities and System Deliverability Upgrades, including, but not limited to, the
following information:  (1) progress to date; (2) a description of the activities since the last
report; (3) a description of the action items for the next period; and (4) the delivery status of
equipment ordered.

24.3Updated Information Submission by Developer.

The updated information submission by the Developer, including manufacturer

information, shall occur no later than one hundred eighty (180) Calendar Days prior to the Trial Operation.  Developer shall submit a completed copy of the Large Generating Facility data
requirements contained in Appendix 1 to the Standard Large Facility Interconnection Procedures. It shall also include any additional information provided to Connecting Transmission Owner for the Interconnection Facilities Study.  Information in this submission shall be the most current
Large Generating Facility design or expected performance data.  Information submitted for
stability models shall be compatible with NYISO standard models.  If there is no compatible
model, the Developer will work with a consultant mutually agreed to by the Parties to develop and supply a standard model and associated information.

If the Developer’s data is different from what was originally provided to Connecting

Transmission Owner and NYISO pursuant to an Interconnection Study Agreement among

Connecting Transmission Owner, NYISO and Developer and this difference may be reasonably
expected to affect the other Parties’ facilities or the New York State Transmission System, but
does not require the submission of a new Interconnection Request, then NYISO will conduct
appropriate studies to determine the impact on the New York State Transmission System based
on the actual data submitted pursuant to this Article 24.3.  Such studies will provide an estimate
of any additional modifications to the New York State Transmission System, Connecting

Transmission Owner’s Attachment Facilities or System Upgrade Facilities or System

Deliverability Upgrades based on the actual data and a good faith estimate of the costs thereof.
The Developer shall not begin Trial Operation until such studies are completed.  The Developer

59

SERVICE AGREEMENT NO. 2593

shall be responsible for the cost of any modifications required by the actual data, including the cost of any required studies.

24.4Information Supplementation.

Prior to the Commercial Operation Date, the Developer and Connecting Transmission
Owner shall supplement their information submissions described above in this Article 24 with
any and all “as-built” Large Generating Facility information or “as-tested” performance
information that differs from the initial submissions or, alternatively, written confirmation that
no such differences exist.  The Developer shall conduct tests on the Large Generating Facility as
required by Good Utility Practice such as an open circuit “step voltage” test on the Large
Generating Facility to verify proper operation of the Large Generating Facility’s automatic
voltage regulator.

Unless otherwise agreed, the test conditions shall include: (1) Large Generating Facility
at synchronous speed; (2) automatic voltage regulator on and in voltage control mode; and (3) a
five percent change in Large Generating Facility terminal voltage initiated by a change in the
voltage regulators reference voltage.  Developer shall provide validated test recordings showing
the responses of Large Generating Facility terminal and field voltages.  In the event that direct
recordings of these voltages is impractical, recordings of other voltages or currents that mirror
the response of the Large Generating Facility’s terminal or field voltage are acceptable if

information necessary to translate these alternate quantities to actual Large Generating Facility terminal or field voltages is provided.  Large Generating Facility testing shall be conducted and results provided to the Connecting Transmission Owner and NYISO for each individual
generating unit in a station.

Subsequent to the Commercial Operation Date, the Developer shall provide Connecting
Transmission Owner and NYISO any information changes due to equipment replacement, repair,
or adjustment.  Connecting Transmission Owner shall provide the Developer and NYISO any
information changes due to equipment replacement, repair or adjustment in the directly
connected substation or any adjacent Connecting Transmission Owner substation that may affect
the Developer Attachment Facilities equipment ratings, protection or operating requirements.
The Developer and Connecting Transmission Owner shall provide such information no later than
thirty (30) Calendar Days after the date of the equipment replacement, repair or adjustment.

ARTICLE 25. INFORMATION ACCESS AND AUDIT RIGHTS

25.1Information Access.

Each Party (“Disclosing Party”) shall make available to another Party (“Requesting

Party”) information that is in the possession of the Disclosing Party and is necessary in order for
the Requesting Party to: (i) verify the costs incurred by the Disclosing Party for which the
Requesting Party is responsible under this Agreement; and (ii) carry out its obligations and
responsibilities under this Agreement.  The Parties shall not use such information for purposes
other than those set forth in this Article 25.1 of this Agreement and to enforce their rights under
this Agreement.

25.2Reporting of Non-Force Majeure Events.

Each Party (the “Notifying Party”) shall notify the other Parties when the Notifying Party becomes aware of its inability to comply with the provisions of this Agreement for a reason other than a Force Majeure event.  The Parties agree to cooperate with each other and provide
necessary information regarding such inability to comply, including the date, duration, reason for the inability to comply, and corrective actions taken or planned to be taken with respect to such inability to comply.  Notwithstanding the foregoing, notification, cooperation or information
provided under this Article shall not entitle the Party receiving such notification to allege a cause for anticipatory breach of this Agreement.

25.3Audit Rights.

Subject to the requirements of confidentiality under Article 22 of this Agreement, each
Party shall have the right, during normal business hours, and upon prior reasonable notice to
another Party, to audit at its own expense the other Party’s accounts and records pertaining to the
other Party’s performance or satisfaction of its obligations under this Agreement.  Such audit
rights shall include audits of the other Party’s costs, calculation of invoiced amounts, and each
Party’s actions in an Emergency State.  Any audit authorized by this Article shall be performed
at the offices where such accounts and records are maintained and shall be limited to those
portions of such accounts and records that relate to the Party’s performance and satisfaction of
obligations under this Agreement.  Each Party shall keep such accounts and records for a period
equivalent to the audit rights periods described in Article 25.4 of this Agreement.

25.4Audit Rights Periods.

25.4.1 Audit Rights Period for Construction-Related Accounts and Records.

Accounts and records related to the design, engineering, procurement, and construction of Connecting Transmission Owner’s Attachment Facilities and System Upgrade Facilities and

ARTICLE 26. SUBCONTRACTORS

26.1General.

Nothing in this Agreement shall prevent a Party from utilizing the services of any

subcontractor as it deems appropriate to perform its obligations under this Agreement; provided, however, that each Party shall require its subcontractors to comply with all applicable terms and conditions of this Agreement in providing such services and each Party shall remain primarily liable to the other Parties for the performance of such subcontractor.

26.2Responsibility of Principal.

The creation of any subcontract 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 Parties for the acts or omissions of any subcontractor the hiring Party hires as if no subcontract had been made; provided, however, that in no event shall the NYISO or Connecting Transmission Owner be liable for the actions or inactions of the Developer or its subcontractors with respect to
obligations of the Developer under Article 5 of this Agreement.  Any applicable obligation
imposed by this Agreement upon the hiring Party shall be equally binding upon, and shall be construed as having application to, any subcontractor of such Party.

The obligations under this Article 26 will not be limited in any way by any limitation of subcontractor’s insurance.

ARTICLE 27. DISPUTES

27.1Submission.

In the event any Party has a dispute, or asserts a claim, that arises out of or in connection
with this Agreement or its performance (a “Dispute”), such Party shall provide the other Parties
with written notice of the Dispute (“Notice of Dispute”).  Such Dispute shall be referred to a
designated senior representative of each Party for resolution on an informal basis as promptly as
practicable after receipt of the Notice of Dispute by the other Parties.  In the event the designated
representatives are unable to resolve the Dispute through unassisted or assisted negotiations
within thirty (30) Calendar Days of the other Parties’ receipt of the Notice of Dispute, such
Dispute may, upon mutual agreement of the Parties, be submitted to arbitration and resolved in
accordance with the arbitration procedures set forth below.  In the event the Parties do not agree
to submit such Dispute to arbitration, each Party may exercise whatever rights and remedies it
may have in equity or at law consistent with the terms of this Agreement.
