Connecting Transmission Owner, at the Interconnection Customer’s option, a guarantee, a surety
bond, letter of credit or other form of security that is reasonably acceptable to the Connecting
Transmission Owner and is consistent with the Uniform Commercial Code of the jurisdiction
where the Point of Interconnection is located.  Such security for payment shall be in an amount
sufficient to cover the costs for constructing, designing, procuring, and installing the applicable
portion of the Connecting Transmission Owner’s Interconnection Facilities and Upgrades and
shall be reduced on a dollar-for-dollar basis for payments made to the Connecting Transmission
Owner under this Agreement during its term.  The Connecting Transmission Owner may draw
on any such security to the extent that the Interconnection Customer fails to make any payments
due under this Agreement.  In addition:

6.3.1   The guarantee must be made by an entity that meets the creditworthiness

requirements of the Connecting Transmission Owner, and contain terms and conditions that guarantee payment of any amount that may be due from the Interconnection Customer, up to an agreed-to maximum amount.

6.3.2   The letter of credit or surety bond must be issued by a financial institution or
insurer reasonably acceptable to the Connecting Transmission Owner and must
specify a reasonable expiration date.

6.3.3   Notwithstanding the above, Security posted for System Upgrade Facilities for a
Small Generating Facility required to enter the Class Year process, or cash or
Security provided for System Deliverability Upgrades, shall meet the
requirements for Security contained in Attachment S to the ISO OATT.

Article 7Assignment, Liability, Indemnity, Force Majeure, Consequential Damages, and
Default

7.1Assignment

This Agreement, and each and every term and condition hereof, shall be binding upon and inure to the benefit of the Parties hereto and their respective successors and assigns. This Agreement may be assigned by either Party upon 15 Business Days prior written notice and opportunity to object by the other Party; provided that:

7.1.1   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 that the Interconnection Customer promptly

notifies the NYISO and the Connecting Transmission Owner of any such

assignment. A Party may assign this Agreement without the consent of the other Party in connection with the sale, merger, restructuring, or transfer of a substantial portion of all of its assets, including the Interconnection Facilities it owns, so long as the assignee in such a transaction directly assumes all rights, duties and
obligation arising under this Agreement.

7.1.2   The Interconnection Customer 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 Small Generating
Facility.

7.1.3   Any attempted assignment that violates this article is void and ineffective.
Assignment shall not relieve a Party of its obligations, nor shall a Party’s
obligations be enlarged, in whole or in part, by reason thereof. An assignee is
responsible for meeting the same financial, credit, and insurance obligations as
the Interconnection Customer. Where required, consent to assignment will not be
unreasonably withheld, conditioned or delayed.

7.2Limitation of Liability

Each Party’s liability to the other Party for any loss, cost, claim, injury, liability, or

expense, including reasonable attorney’s fees, relating to or arising from any act or omission in its performance of this Agreement, shall be limited to the amount of direct damage actually incurred.  In no event shall either Party be liable to the other Party for any indirect, special, consequential, or punitive damages.

7.3Indemnity

7.3.1   This provision protects each Party from liability incurred to third parties as a
result of carrying out the provisions of this Agreement. Liability under this
provision is exempt from the general limitations on liability found in article 7.2.

7.3.2   Each Party (the “Indemnifying Party”) shall at all times indemnify, defend, and
hold harmless the other Party (the “ Indemnified Party”) from, any and all
damages, losses, claims, including claims and actions relating to injury to or death
of any person 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 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 by the Indemnified Party, or (ii) the
violation by the Indemnifying Party of any Environmental Law or the release by the Indemnifying Party of a Hazardous Substance.

7.3.3   If a Party is entitled to indemnification under this article as a result of a claim by a
third party, and the Indemnifying Party fails, after notice and reasonable
opportunity to proceed under this article, 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.

7.3.4   If the Indemnifying Party is obligated to indemnify and hold the Indemnified

Party harmless under this article, 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.

7.3.5   Promptly after receipt by the 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 this article 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.

7.4Consequential Damages

Other than as expressly provided for in this Agreement, neither Party shall be liable under any provision of this Agreement for any losses, damages, costs or expenses for any special,
indirect, incidental, consequential, or 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; provided, however, that damages for which a Party may be liable to the
other Party under another agreement will not be considered to be special, indirect, incidental, or
consequential damages hereunder.

7.5Force Majeure

7.5.1   As used in this article, a “Force Majeure Event” shall mean “any act of God, labor
disturbance, act of the public enemy, war, insurrection, riot, fire, storm or flood,
explosion, breakage or accident to machinery or equipment, any order, regulation

or restriction imposed by governmental, military or lawfully established civilian
authorities, or any other cause beyond a Party’s control. A Force Majeure Event
does not include an act of negligence or intentional wrongdoing.” For the
purposes of this article, this definition of Force Majeure shall supersede the
definitions of Force Majeure set out in Section 32.10.1 of the ISO OATT.

7.5.2   If a Force Majeure Event prevents a Party from fulfilling any obligations under

this Agreement, the Party affected by the Force Majeure Event (“Affected Party”)
shall promptly notify the other Party, either in writing or via the telephone, of the
existence of the Force Majeure event. The notification must specify in reasonable
detail the circumstances of the Force Majeure Event, its expected duration, and
the steps that the Affected Party is taking to mitigate the effects of the event on its
performance. The Affected Party shall keep the other Party informed on a

continuing basis of developments relating to the Force Majeure Event until the event ends. The Affected Party will be entitled to suspend or modify its
performance of obligations under this Agreement (other than the obligation to make payments) only to the extent that the effect of the Force Majeure Event cannot be mitigated by the use of Reasonable Efforts. The Affected Party will use Reasonable Efforts to resume its performance as soon as possible.

7.6Breach and Default

7.6.1   No Breach of this Agreement shall exist where such failure to discharge an
obligation (other than the payment of money) is the result of a Force Majeure
Event or the result of an act or omission of the other Party. Upon a Breach, the
non-breaching Party shall give written notice of such Breach to the Breaching
Party. Except as provided in article 7.6.2, the Breaching Party shall have 60
calendar days from receipt of the Breach notice within which to cure such Breach;
provided however, if such Breach is not capable of cure within 60 calendar days,
the Breaching Party shall commence such cure within 20 calendar days after
notice and continuously and diligently complete such cure within six months from
receipt of the Breach notice; and, if cured within such time, the Breach specified
in such notice shall cease to exist.

7.6.2   If a Breach is not cured as provided in this article, or if a Breach is not capable of
being cured within the period provided for herein, a Default shall exist and the
non-defaulting Party shall thereafter have the right to terminate this Agreement, in
accordance with article 3.3 hereof, by written notice to the defaulting Party at any
time until cure occurs, and be relieved of any further obligation hereunder and,
whether or not that Party terminate this Agreement, to recover from the defaulting
Party all amounts due hereunder, plus all other damages and remedies to which
they are entitled at law or in equity. The provisions of this article shall survive
termination of this Agreement.

7.6.3   In cases where the Interconnection Customer has elected to proceed under Section

32.3.5.3 of the SGIP, if the Interconnection Request is withdrawn or deemed withdrawn pursuant to the SGIP during the term of this Agreement, this Agreement shall terminate.

Article 8:Insurance

8.1 The Interconnection Customer shall, at its own expense, maintain in force general

liability insurance without any exclusion for liabilities related to the interconnection

undertaken pursuant to this Agreement. The amount of such insurance shall be sufficient
to insure against all reasonably foreseeable direct liabilities given the size and nature of
the generating equipment being interconnected, the interconnection itself, and the
characteristics of the system to which the interconnection is made. Such insurance
coverage is specified in Attachment 7 to this Agreement. The Interconnection Customer
shall obtain additional insurance only if necessary as a function of owning and operating
a generating facility. Such insurance shall be obtained from an insurance provider
authorized to do business in New York State where the interconnection is located.
Certification that such insurance is in effect shall be provided upon request of the
Connecting Transmission Owner, except that the Interconnection Customer shall show
proof of insurance to the Connecting Transmission Owner no later than ten Business
Days prior to the anticipated commercial operation date. An Interconnection Customer of
sufficient creditworthiness may propose to self-insure for such liabilities, and such a
proposal shall not be unreasonably rejected.

8.2 The Connecting Transmission Owner agree to maintain general liability insurance or self-

insurance consistent with the existing commercial practice. Such insurance or self-
insurance shall not exclude the liabilities undertaken pursuant to this Agreement.

8.3 The Parties further agree to notify one another whenever an accident or incident occurs

resulting in any injuries or damages that are included within the scope of coverage of such insurance, whether or not such coverage is sought.

Article 9: Confidentiality

9.1 Confidential Information shall mean any confidential and/or proprietary information

provided by one Party to the other Party that is clearly marked or otherwise designated
“Confidential.” For purposes of this Agreement all design, operating specifications, and
metering data provided by the Interconnection Customer shall be deemed Confidential
Information regardless of whether it is clearly marked or otherwise designated as such.
Confidential Information shall include, without limitation, information designated as such
by the NYISO Code of Conduct contained in Attachment F to the ISO OATT.

9.2 Confidential Information does not include information previously in the public domain,

required to be publicly submitted or divulged by Governmental Authorities (after notice
to the other Party and after exhausting any opportunity to oppose such publication or
release), or necessary to be divulged in an action to enforce this Agreement. Each Party
receiving Confidential Information shall hold such information in confidence and shall

not disclose it to any third party nor to the public without the prior written authorization from the Party providing that information, except to fulfill obligations under this
Agreement, or to fulfill legal or regulatory requirements.

9.2.1   Each Party shall employ at least the same standard of care to protect Confidential
Information obtained from the other Party as it employs to protect its own
Confidential Information.

9.2.2   Each Party is entitled to equitable relief, by injunction or otherwise, to enforce its
rights under this provision to prevent the release of Confidential Information
without bond or proof of damages, and may seek other remedies available at law
or in equity for breach of this provision.

9.3 Notwithstanding anything in this article to the contrary, and pursuant to 18 CFR §

lb.20, if FERC, during the course of an investigation or otherwise, requests

information from the other Party that is otherwise required to be maintained in
confidence pursuant to this Agreement, the Party shall provide the requested
information to FERC, within the time provided for in the request for information.
In providing the information to FERC, the Party may, consistent with 18 CFR §
388.112, request that the information be treated as confidential and non-public by
FERC and that the information be withheld from public disclosure. Each Party is
prohibited from notifying the other Party to this Agreement prior to the release of
the Confidential Information to FERC. The Party shall notify the other Party to
this Agreement when it is notified by FERC that a request to release Confidential
Information has been received by FERC, at which time either of the Parties may
respond before such information would be made public, pursuant to 18 CFR §
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.

9.4 Consistent with the provisions of this article 9, the Parties to this Agreement will

cooperate in good faith to provide each other, Affected Systems, Affected System Operators, and state and federal regulators the information necessary to carry out the terms of the SGIP and this Agreement.

Article 10: Disputes

10.1 The Connecting Transmission Owner and Interconnection Customer agree to attempt to

resolve all disputes arising out of the interconnection process according to the provisions of this article.

10.2In the event of a dispute, the Parties will first attempt to promptly resolve it on an

informal basis. If the Parties cannot promptly resolve the dispute on an informal basis, then either Party shall provide the other Party with a written Notice of Dispute. Such notice shall describe in detail the nature of the dispute.

10.3 If the dispute has not been resolved within two Business Days after receipt of the notice,

either Party may contact FERC’s Dispute Resolution Service (“DRS”) for assistance in resolving the dispute.

10.4 The DRS will assist the Parties in either resolving their dispute or in selecting an

appropriate dispute resolution venue (e.g., mediation, settlement judge, early neutral

evaluation, or technical expert) to assist the Parties in resolving their dispute. The result of this dispute resolution process will be binding only if the Parties agree in advance. DRS can be reached at 1-877-337-2237 or via the internet at

http://www.ferc.gov/legal/adr.asp.

10.5Each Party agrees to conduct all negotiations in good faith and will be responsible for

one-half of any costs paid to neutral third-parties.

10.6 If either Party elects to seek assistance from the DRS, or if the attempted dispute

resolution fails, then either Party may exercise whatever rights and remedies it may have in equity or law consistent with the terms of this Agreement.

Article 11: Taxes

11.1 The Parties agree to follow all applicable tax laws and regulations, consistent with

FERC policy and Internal Revenue Service requirements.

11.2 Each Party shall cooperate with the other Parties to maintain the other Party’s tax status.

Nothing in this Agreement is intended to adversely affect the tax status of either Party
including the status of any Connecting Transmission Owner with respect to the issuance of bonds including, but not limited to, Local Furnishing Bonds. Notwithstanding any
other provisions of this Agreement, LIPA, NYPA and Consolidated Edison Company of New York, Inc. shall not be required to comply with any provisions of this Agreement
that would result in the loss of tax-exempt status of any of their Tax-Exempt Bonds or
impair their ability to issue future tax-exempt obligations. For purposes of this provision, Tax-Exempt Bonds shall include the obligations of the Long Island Power Authority,
NYPA and Consolidated Edison Company of New York, Inc., the interest on which is not included in gross income under the Internal Revenue Code.

11.3 LIPA and NYPA do not waive their exemptions, pursuant to Section 201(f) of the FPA,

from Commission jurisdiction with respect to the Commission’s exercise of the FPA’s general ratemaking authority.

11.4 Any payments due to the Connecting Transmission Owner under this Agreement shall be

adjusted to include any tax liability incurred by the Connecting Transmission Owner with respect to the interconnection request which is the subject of this Agreement.  Such
adjustments shall be made in accordance with the provisions of Article 5.17 of the LGIA in Attachment X of the ISO OATT. Except where otherwise noted, all costs, deposits,
financial obligations and the like specified in this Agreement shall be assumed not to
reflect the impact of applicable taxes.

Article 12: Miscellaneous

12.1 Governing Law, Regulatory Authority, and Rules

The validity, interpretation and enforcement of this Agreement and each of its provisions shall be governed by the laws of the state of New York, without regard to its conflicts of law principles. This Agreement is subject to all Applicable Laws and Regulations. Each Party
expressly reserves the right to seek changes in, appeal, or otherwise contest any laws, orders, or regulations of a Governmental Authority.

12.2Amendment

The Parties may amend this Agreement by a written instrument duly executed by the Parties, or under article 12.12 of this Agreement.

12.3 No Third-Party Beneficiaries

This Agreement is not intended to and does not create rights, remedies, or benefits of any character whatsoever in favor of any persons, corporations, associations, or entities other than the Parties, and the obligations herein assumed are solely for the use and benefit of the Parties, their successors in interest and where permitted, their assigns. Notwithstanding the foregoing, any
subcontractor of the Connecting Transmission Owner assisting that Party with the
Interconnection Request covered by this Agreement shall be entitled to the benefits of
indemnification provided for under Article 7.3 of this Agreement and the limitation of liability
provided for in Article 7.2 of this Agreement.

12.4Waiver

12.4.1 The failure of a Party to this Agreement to insist, on any occasion, upon strict

performance of any provision of this Agreement will not be considered a waiver of any obligation, right, or duty of, or imposed upon, such Party.

12.4.2 Any waiver at any time by a Party of its rights with respect to this Agreement
shall not be deemed a continuing waiver or a waiver with respect to any other
failure to comply with any other obligation, right, duty of this Agreement.
Termination or default of this Agreement for any reason by Interconnection
Customer shall not constitute a waiver of the Interconnection Customer’s legal
rights to obtain an interconnection from the NYISO. Any waiver of this
Agreement shall, if requested, be provided in writing.

12.5Entire Agreement

This Agreement, including all Attachments, constitutes the entire agreement between the Parties with reference to the subject matter hereof, and supersedes all prior and contemporaneous understandings or agreements, oral or written, between the Parties with respect to the subject matter of this Agreement. There are no other agreements, representations, warranties, or
covenants which constitute any part of the consideration for, or any condition to, either Party’s compliance with its obligations under this Agreement.

12.6 Multiple Counterparts

This Agreement may be executed in two or more counterparts, each of which is deemed an original but all constitute one and the same instrument.

12.7No Partnership

This Agreement shall not be interpreted or construed to create an association, joint

venture, agency relationship, or partnership between the Parties or to impose any partnership

obligation or partnership liability upon either Party. Neither Party shall have any right, power or authority to enter into any agreement or undertaking for, or act on behalf of, or to act as or be an agent or representative of, or to otherwise bind, the other Party.

12.8Severability

If any provision or portion of this Agreement shall for any reason be held or adjudged to

be invalid or illegal or unenforceable by any court of competent jurisdiction or other

Governmental Authority, (1) such portion or provision shall be deemed separate and

independent, (2) the Parties shall negotiate in good faith to restore insofar as practicable the

benefits to each Party that were affected by such ruling, and (3) the remainder of this Agreement shall remain in full force and effect.

12.9 Security Arrangements

Infrastructure security of electric system equipment and operations and control hardware and software is essential to ensure day-to-day reliability and operational security. FERC expects the NYISO, the Connecting Transmission Owner, Market Participants, and Interconnection
Customers interconnected to electric systems to comply with the recommendations offered by the President’s Critical Infrastructure Protection Board and, eventually, best practice
recommendations from the electric reliability authority. All public utilities are expected to meet basic standards for system infrastructure and operational security, including physical,
operational, and cyber-security practices.

12.10  Environmental Releases

Each Party shall notify the other Party, first orally and then in writing, of the release of
any hazardous substances, any asbestos or lead abatement activities, or any type of remediation
activities related to the Small Generating Facility or the Interconnection Facilities, each of which
may reasonably be expected to affect the other Party. The notifying Party shall: (1) provide the
notice as soon as practicable, provided such Party makes a good faith effort to provide the notice
no later than 24 hours after such Party becomes aware of the occurrence, and (2) promptly

furnish to the other Party copies of any publicly available reports filed with any governmental authorities addressing such events.

12.11  Subcontractors

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 Party for the performance of such subcontractor.

12.11.1 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 Party to the extent provided for in
Sections 32.7.2 and 32.7.3 above 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 Connecting Transmission
Owner be liable for the actions or inactions of the Interconnection
Customer or its subcontractors with respect to obligations of the
Interconnection Customer under 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.

12.11.2The obligations under this article will not be limited in any way by any

limitation of subcontractor’s insurance.

12.12  Reservation of Rights

Nothing in this Agreement shall alter the right of the Connecting Transmission Owner to make unilateral filings with FERC to modify this Agreement with respect to any rates, terms and conditions, charges, classifications of service, rule or regulation under Section 205 or any other applicable provision of the Federal Power Act and FERC’s rules and regulations thereunder
which rights are expressly reserved herein, and the existing rights of the Interconnection
Customer to make a unilateral filing with FERC to modify this Agreement under any applicable provision of the Federal Power Act and FERC’s rules and regulations are also expressly reserved herein; provided that each Party shall have the right to protest any such filing by the other Party and to participate fully in any proceeding before FERC in which such modifications may be
considered.  Nothing in this Agreement shall limit the rights of the Parties or of FERC under
Sections 205 or 206 of the Federal Power Act and FERC’s rules and regulations, except to the
extent that the Parties otherwise agree as provided herein.
