Conversion.The Borrower may from time to time elect to Convert any Advance (or portion thereof) of any Type to one or more
Advances of the same or any other Type on the following terms and subject to the following conditions:

Each
such Conversion shall be made as to all Advances comprising a single Borrowing, on notice given not later than 11:00 A.M. (New York City time) on the third Business Day prior
to the date of the proposed Conversion, in the case of any such Conversion into LIBOR Rate Advances, or on the Business Day of the proposed Conversion, in the case of any such Conversion into Base
Rate Advances, by the Borrower to the Administrative Agent, who shall give each Lender prompt notice thereof. Each such notice of Conversion (a "Notice of
Conversion") shall be in substantially the form ofExhibit 2.03(b)(i), specifying therein the requested (1) date
of such Conversion, (2) Type of, and, with respect to LIBOR Rate Advances, Interest Period applicable to, the Advances (or portions thereof) proposed to be Converted, (3) except in the
case of a Conversion described in subsection (iv), below, Type of Advances to which such Advances (or portions thereof) are proposed to be Converted, (4) in the case of a Conversion to LIBOR
Rate Advances, initial Interest Period to be applicable to the Advances resulting from such Conversion and (5) aggregate amount of Advances (or portions thereof) proposed to be Converted. In
the case of a proposed Conversion into LIBOR Rate Advances, the Administrative Agent shall promptly notify each Lender of the interest rate to be applicable to the Advances resulting from such
Conversion pursuant to Section 2.03(b)(ii) promptly after determination thereof.

LIBOR
Rate Advances may not be Converted on a date other than the last day of the Interest Period then applicable thereto, unless (i) the corresponding amounts, if any, payable to
the Lenders pursuant to Section 4.07 are paid contemporaneously with such Conversion and (ii) such corresponding amounts, if any, required to be so paid, are paid only from cash
contributions to the equity of the Borrower made for such purpose at such time.

No
Conversion may be requested by the Borrower hereunder unless made in compliance with this Section 2.03.

Any
selection by the Borrower of a longer or shorter Interest Period to be applicable to any LIBOR Rate Advance shall be deemed a Conversion pursuant to this Section 2.03, shall
be governed by the terms and conditions hereof and shall be notified to the Administrative Agent as herein provided. If no Notice of Conversion in respect of an Advance is received by the
Administrative Agent prior to the end of any Interest Period as provided in subsection (a)(i), above, such Advance shall be Converted to a Base Rate Advance.

No
Conversion to a LIBOR Rate Advance shall be made (i) so long as an Borrower Event of Default has occurred and is continuing and the Administrative Agent has determined that
such Conversion is not appropriate or (ii) after the date that is one month prior to the Maturity Date.



Anything in Section 2.01 or 2.02 to the contrary notwithstanding:

at
no time shall more than four different Interest Periods be in effect as to outstanding Borrowings hereunder;

each
Borrowing hereunder (whether from the making or Conversion of Advances hereunder, or both) which is to be comprised of LIBOR Rate Advances shall be in a minimum aggregate principal
amount no less than $1,000,000; and

no
Lender having a Working Capital Commitment shall be obligated to make a Working Capital Advance if, on and after the first anniversary of the Second Completion Date, on the date of
any such requested Advance, there shall not have been, during the immediately preceding twelve month period,

7

---

at least one thirty (30) consecutive day period during which no Working Capital Advances were outstanding.

Each
Notice of Borrowing and Notice of Conversion shall be irrevocable and binding on the Borrower after delivery thereof. In the case of any Borrowing which the related Notice of
Borrowing or Notice of Conversion specifies is to be comprised of LIBOR Rate Advances, the Borrower shall indemnify each Lender against any loss, cost or expense incurred by such Lender as a result of
any failure to fulfill on or before the date specified in such Notice of Borrowing or Notice of Conversion for such Borrowing the applicable conditions (if any) set forth in this Article II
(other than failure pursuant to the provisions of Section 2.03(b) or (c)) or in Article V, including any such loss (including loss of anticipated profits where such failure shall not
have been beyond the reasonable control of the Borrower), cost or expense incurred by reason of the liquidation or re-employment of deposits or other funds acquired by such Lender to fund
the Advance to be made by such Lender as part of such Borrowing when such Advance, as a result of such failure, is not made on such date.

So
long as any Swap Agreement is in effect with respect to any Advances, the Borrower shall maintain as LIBOR Rate Advances having Interest Periods corresponding to the payment dates
under such Swap Agreement an aggregate amount of Advances at least equal to the notional amount then in effect under such Swap Agreement, except to the extent that the Borrower would be prevented from
complying with this Section 2.03(c)(iii) by operation of Section 2.01, subsections (i) or (ii) of this Section 2.03(c) or Section 4.02(b).

Default Interest.Any principal amounts payable hereunder that are not paid when due shall (to the fullest extent permitted
by law) bear interest, from the date when due until paid in full, at a rate per annum equal at all times to the Default Rate.

THE LETTERS OF CREDIT

Commitments.Each Lender irrevocably agrees severally, on the terms and conditions contained in this Agreement, to
participate in each Letter of Credit and each Drawing thereunder in an aggregate amount not to exceed the product of (x) such Lender's Percentage and (y) the Aggregate LC Commitment (the
foregoing obligations being hereinafter referred to as each Lender's "LC Commitment"). Simultaneously with the issuance of each Letter of Credit, the
applicable LC Issuer shall be deemed to have sold and transferred to each Lender, and each Lender shall be deemed to have purchased and received from the applicable LC Issuer, in each case irrevocably
and without any further action by any party, an undivided interest and participation in each Letter of Credit and each Drawing in an amount equal to such Lender's LC Commitment. The Administrative
Agent shall promptly advise each Lender of any change in the Outstanding Amount, the Stated Amount or the Expiration Date in respect of each Letter of Credit, the cancellation or other termination of
a Letter of Credit and any Drawing;provided, however,that failure to provide such notice shall not limit or impair the rights of the applicable LC
Issuer hereunder or under the Loan Documents.

Amount and Term of Letters of Credit.(a) On the terms and subject to the conditions set forth herein (i) the
Project LC Issuer hereby agrees to issue the Project Letters of Credit to support the Development Projects' security and payment obligations under the Interconnection Agreements and Sithe Fore River's
security obligations under the Related Facilities Agreement, and (ii) the DSR LC Issuer hereby agrees to issue the DSR Letter of Credit to support the Borrower's obligation to provide to the
Collateral Agent, for the benefit of the Lenders, with the Debt Service Reserve Requirement upon the Second Completion Date, in each case in the applicable Stated Amount. The Letters of Credit shall
be effective on the date issued and, unless terminated or early expiring in accordance with their terms, shall expire on the Expiration Date, as the same may be extended. The amount available under
each Letter of Credit shall be (i) reduced by the amount of any Drawing thereunder, (ii) reduced by the amount stated in any Reduction Certificate submitted by the Borrower as permitted
pursuant to such Letter of Credit and (ii) reinstated, in the case of the DSR Letter of Credit or, prior to issuance of the DSR Letter of Credit, under any Interconnection Security Letter of
Credit, in connection with any repayment of a LC Loan advanced as a result of a Drawing thereunder,providedthat LC Loans remain available, pursuant to
the terms of this Agreement, at the time of such reinstatement.

Each
Letter of Credit shall be issued on not less than three Business Days' prior written notice thereof to the Administrative Agent (which shall promptly distribute copies of such
notice to the Lenders) and the applicable LC Issuer. Each such notice (a "Request for Issuance") shall specify (i) the date of
issuance and the Expiration Date thereof and (ii) such other information as shall demonstrate compliance of the Letter of Credit with the requirements specified therefor in this Agreement. Such
Request for Issuance shall be irrevocable unless modified or rescinded by the Borrower by written notice to the Administrative Agent and the applicable LC Issuer at least two Business Days prior to
the proposed date of issuance specified therein. Not later than 11:00 A.M. (New York City time) on the proposed date of issuance specified in such Request for Issuance, and upon fulfillment of
the applicable conditions precedent and other requirements set forth herein, the applicable LC Issuer shall issue such Letter of Credit and provide notice and a copy thereof to the Administrative
Agent.

Reimbursement of LC Issuer.(a) Subject to Section 3.03(b), the Borrower hereby agrees to pay or cause to be
paid to the DSR LC Issuer or the Project LC Issuer, as the case may be, not later than 5:00 P.M. (New York City time) on the Business Day following each date on which such LC Issuer shall pay
any amount under any Letter of Credit (the "LC Payment Date") issued by such LC Issuer (but in no event prior to the time of any such payment by such LC
Issuer) without requirement for presentation or demand of any kind whatsoever, a sum equal to the amount so paid plus interest at the Base Rate until such amount is reimbursed (including by using the
proceeds of an LC Loan);provided,that such LC Issuer shall, promptly inform the Borrower in writing of the amount so paid. The

9

---

Borrower's obligation to make payments under this subsection (a), and the right of such LC Issuer to receive the same, are absolute and unconditional as provided in Section 3.03, and the
Borrower agrees that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever;provided,that no delay in
making any payment shall constitute a default hereunder so long as the Borrower uses the LC Loans to make such payments immediately upon becoming available.

If
the DSR LC Issuer or the Project LC Issuer, as the case may be, shall not have been reimbursed in full for any payment made by such LC Issuer under any Letter of Credit on any LC
Payment Date, the Administrative Agent shall promptly notify each other Lender. Each such Lender shall, on the day of such notification, make a loan to the Borrower, by depositing with the Collateral
Agent for the account of such LC Issuer, in immediately available funds, an amount equal to the amount of such Lender's participation in such Drawing plus any interest accrued in accordance with
clause (a) above. In the event that any Lender fails to make available to the Collateral Agent for the account of such LC Issuer the amount of such loan, such LC Issuer shall be entitled to
recover such amount on demand from such Lender together with interest thereon at (i) for the first three (3) days of nonpayment, the Federal Funds Rate and (ii) thereafter, the
Federal Funds Rate plus 2.00%. Each loan by a Lender pursuant to this Section 3.03(b) shall be deemed a "LC Loan" under this Agreement. LC Loans
which may be made by each Lender shall be evidenced by a LC Loan Note of the Borrower in the form ofExhibit 3.03(b),dated the Closing Date,
payable to such Lender for the account of its Lending Office in an aggregate principal amount equal to its LC Commitment and otherwise duly completed. At no time shall the aggregate principal amount
of all outstanding LC Loans exceed the Aggregate LC Commitment. The Borrower shall pay interest pursuant to Section 4.05 of the Depositary Agreement on the unpaid principal amount of each LC
Loan resulting from a Drawing, from the date of such LC Loan until such principal amount has been repaid in full. Such interest shall be paid at a rate per annum, at the Borrower's option, either,
(1) the rate then applicable to Base Rate Project Advances plus 0.125% or (2) the rate then applicable to LIBOR Rate Project Advances plus 0.125%,provided,
however,that interest with respect to LC Loans resulting from drawings under either Interconnection Payment Letter of Credit, shall be paid at a rate per annum, at the
Borrower's option, either (1) the rate then applicable to Base Rate Project Advances or (2) the rate then applicable to LIBOR Rate Project Advances. The Borrower shall repay the
principal amount of each LC Loan as, when and to the extent
monies are available for such purpose pursuant to Section 4.05 of the Depositary Agreement,provided, however,that principal owed in connection
with LC Loans resulting from drawings under either Interconnection Payment Letter of Credit, shall be payable in installments payable on each Payment Date in accordance with the repayment schedule set
forth on Schedule 2.01(e), with any remaining principal, interest, fees and costs due in respect of such LC Loans due and payable on the Maturity Date. All LC Loans shall mature on the Maturity
Date.

In
the event that any LC Loan described in Section 3.03(b) cannot for any reason be made on the date otherwise required above (including as a result of the occurrence of an Event
of Bankruptcy with respect to the Borrower or any Project Company), then each Lender shall forthwith purchase (as of the date such LC Loan would otherwise have been made) from the applicable LC Issuer
a participation in the unreimbursed portion of the Drawing in an amount equal to the product of such Lender's Percentage of the Aggregate LC Commitment multiplied by the amount of the unreimbursed
portion of such Drawing. Each Lender's obligation to make each such payment to the applicable LC Issuer shall be absolute, unconditional and irrevocable and shall not be affected by any circumstance
whatsoever, including the occurrence or continuance of any Borrower Default, Borrower Event of Default, Project Default or Project Event of Default, or the failure of any other Lender to make any
payment under this 3.03(c), and each Lender further agrees that each such payment shall be made without any offset, abatement, withholding, or reduction whatsoever.

Obligations Absolute.(a) The payment obligations of the Borrower under this Agreement in respect of any payment under
each Letter of Credit and any LC Loans made under Section 3.03(b),

failure, omission or delay on the part of any Lender, the Borrower, or any other Person to enforce, assert or exercise any right, power or remedy conferred by this Agreement or any
other Transaction Document, or any other act or acts on the part of any Lender, the Borrower or any other Person;

the
voluntary or involuntary liquidation, dissolution, sale or other disposition of all or substantially all the assets of, the marshalling of assets and liabilities, receivership,

---

the
release or discharge by operation of law of the Borrower from the performance or observance of any obligation, covenant or agreement contained in any of the Transaction Documents;
and

any
other circumstance or happening whatsoever, whether or not similar to any of the foregoing.

Without
limiting the effect of subsection (a), above, or any provision hereof, the Borrower agrees with the LC Issuers that:

each
LC Issuer is authorized to make payments under each Letter of Credit issued thereby upon the presentation of the documents provided for therein and, subject to
Section 3.04(a)(v), conforming to the requirements thereof, without regard to whether (1) the Borrower has failed to fulfill any of its obligations with respect to any Transaction
Document or (2) any Borrower Default, Borrower Event of Default or other default has occurred thereunder or hereunder;

each
LC Issuer shall be entitled to rely upon any certificate, notice, demand or other communication (whether by cable, telegram, telex or other written communication) including any
thereof from or purporting to be from any beneficiary of any Letter of Credit, believed by it in good faith to be genuine and to have been signed or sent by the proper Person or Persons (and no such
reliance or failure shall place either LC Issuer under any liability to the Borrower or any Lender or limit or otherwise affect the Borrower or any Lender's obligations under this Agreement); and

any
action, inaction or omission on the part of either LC Issuer under or in connection with any Letter of Credit issued thereby or the related instruments or documents, if taken in good
faith and in conformity with such laws, regulations or customs as each such LC Issuer may reasonably deem to be applicable, shall be binding upon the Borrower and each Lender (and shall not place
either LC Issuer under any liability to the Borrower or any Lender or limit or otherwise affect the Borrower's or any Lender's obligations under this Agreement).

None
of the foregoing provisions of this Section 3.04 and Section 3.05 shall be deemed a waiver of, and the Borrower expressly reserves the right to bring suit against
either LC Issuer for, damages arising out
of such LC Issuer's gross negligence or willful misconduct as determined by a court of competent jurisdiction.

Liability of LC Issuers and the Lenders.The Borrower assumes all risks of the acts or omissions of any beneficiary or
transferee of any of the Letters of Credit. None of the LC Issuers, the Lenders, the Administrative Agent nor any of their respective officers or directors shall be liable or responsible for
(a) the use which may be made of any of the Letters of Credit or any acts or omissions of any beneficiary or transferee thereof in connection therewith; (b) the validity, sufficiency or
genuineness of documents, or of any endorsement thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent or forged or any statement therein proves to
be untrue or inaccurate in any respect whatsoever; (c) payment by either LC Issuer against presentation of documents which do not comply with the terms of any of the Letters of Credit issued
thereby, including failure of any documents to bear any reference or adequate reference to such Letter of Credit; or (d) any other circumstances whatsoever in making or failing to make payment
under any of the Letters of Credit, except that the Borrower and any Lender shall have a claim against a LC Issuer, and such LC Issuer shall be liable to the Borrower and any Lender, to the extent,
and only to the extent, of any direct, as opposed to consequential, damages suffered by the Borrower or such Lender as a result of such LC Issuer's willful misconduct or gross negligence as determined
by a court of competent jurisdiction (provided, that such LC Issuer's willful failure to pay under any of the Letters of Credit issued thereby shall not
constitute gross negligence or willful misconduct if such LC Issuer reasonably and in good faith believed itself to be prohibited by law or legal authority from making such payment). In furtherance
and not in limitation of the foregoing, each LC Issuer may accept sight drafts and accompanying certificates presented under any of the Letters of Credit issued thereby that appear on

12

---

their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary.

Extension of the Stated Expiration Date.Thirty (30) days prior to the Stated Expiration Date of any Standby Letter of
Credit, such Stated Expiration Date shall be extended for a period of one year from such Stated Expiration Date and shall thereafter be automatically extended in the same manner for additional
one-year periods until the Maturity Date. Each Standby Letter of Credit shall terminate upon the earliest to occur of (a) the Stated Expiration Date, as such date may have been
extended pursuant to the foregoing sentence, (b) a drawing or drawings under a Standby Letter of Credit by the beneficiary thereof equal to, in the aggregate, the then applicable maximum Stated
Amount thereof, which Stated Amount, or any portion thereof, has not been reinstated in accordance with the provisions of Section 3.02(a), and (c) the delivery of a notice of termination
of such Standby Letter of Credit to each of the Borrower and the beneficiary of such Standby Letter of Credit by the applicable LC Issuer. Following receipt by each of the Borrower and the beneficiary
of the notice described in clause (c) of the preceding sentence, such Standby Letter of Credit shall be terminated on the date specified in such notice.

PAYMENTS



The Borrower shall make, or shall direct the Depositary to make, each payment required to be made by the Borrower hereunder and under the other Loan Documents
without setoff, deduction or counterclaim not later than 12:00 noon (New York City time) on the day when due in Dollars to the Administrative Agent in immediately available funds. Funds received by
the Administrative Agent after such time shall be deemed to have been received on the next Business Day.

All
computations of interest based on the Base Rate and of Fees payable pursuant to Section 4.09 shall be made by the Administrative Agent on the basis of a year of 365 or
366 days, as the case may be. All other computations of interest and Fees hereunder (including computations of interest based on the LIBOR Rate) shall be made by the Administrative Agent on the
basis of a year of 360 days. In each such case, such computation shall be made for the actual number of days (including the first day but excluding the last day) occurring in the period for
which such interest or Fees are payable. Each such determination by the Administrative Agent shall be conclusive and binding for all purposes, absent manifest error.

Whenever
any payment hereunder or under any other Loan Document shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business
Day, and such extension of time shall in such case be included in the computation of payment of interest and Fees hereunder;provided, however, that if
such extension would cause payment of interest on or principal of LIBOR Rate Advances to be made in the next following calendar month, such payment shall be made on the next preceding Business Day and
such reduction of time shall in such case be included in the computation of payment of interest hereunder.



Optional Prepayments.The Borrower may, at any time upon at least one (1) Business Days' notice to the Administrative
Agent stating the proposed date and aggregate principal amount of the prepayment, and if such notice is given the Borrower shall, prepay the outstanding principal amount of Advances comprising part of
the same Borrowing, in whole or ratably in part, together with (A) accrued interest to the date of such prepayment on the principal amount prepaid and (B) the amounts, if any, payable to
each Swap Bank as a result of such prepayment pursuant to any Swap Agreement;provided, however, that (1) each partial prepayment shall be in an
aggregate principal amount, in the case of LIBOR Rate Advances, not less than $1,000,000 or whole number multiple

13

---

thereof and, in the case of Base Rate Advances, not less than $100,000 or whole number multiple thereof, (2) no partial payment of LIBOR Rate Advances shall be permitted unless the remaining
principal amount of such Advances having the same Interest Period shall aggregate at least $10,000,000 or shall have been concurrently Converted in accordance with Sections 2.03(b) and (c) and
(3) no such prepayment of Advances other than Base Rate Advances shall be permitted unless the corresponding amounts, if any, payable pursuant to Section 4.07 are paid contemporaneously
with such prepayment.



Concurrently
with receipt by the Borrower from any Project Company of amounts constituting a mandatory payment under Section 3.02(a) of the Project Company Guarantee, the same
shall be forthwith applied as prepayments in accordance with clause (iii), below.

If
required pursuant to Section 4.09 of the Depositary Agreement to apply all or a portion of amounts on deposit in the Distribution Account, such amounts shall be forthwith
applied as prepayments in accordance with clause (iii) below.

The
proceeds of each prepayment required to be made pursuant to clauses (i) and (ii) above, shall be applied to prepay Advances in an aggregate principal amount which, when
added to any Swap Claims due in connection with such prepayment, would equal the amount of such proceeds. Swap Claims, if any, shall be payable on each such date of prepayment.

All
prepayments of Advances shall be prepaid in inverse order of maturity of such Advances,provided,however, that any Performance
Liquidated Damages (as defined in the EPC Agreements) applied in accordance with Section 4.02(b)(i) shall be applied to reduce outstanding Advances pro rata in accordance with Schedule 2.01(e)attached hereto. The Administrative Agent shall give prompt notice to each Lender of the amount of each prepayment made by the
Borrower under this Section 4.02.

Increased Cost and Reduced Return; Additional Interest; Capital Adequacy.

Increased Cost and Reduced Return.If the adoption of any Requirement of Law or any change therein, or any change in the
interpretation or administration thereof by any Governmental Authority charged with the interpretation or administration thereof, or compliance by any Lender (or its Lending Office) with any request
or directive applicable to such Lender (whether or not having the force of law) of any such Governmental Authority:

shall
subject any Lender (or its Lending Office) to any tax, duty or other charge with respect to its LIBOR Rate Advances, Notes, Commitments or its obligation to make LIBOR Rate
Advances, or shall cause the withdrawal or termination of any previously granted exemption with respect to any taxes or shall change the basis of taxation of, or increase the taxes on, payments to any
Lender (or its Lending Office) of the principal of or interest on its LIBOR Rate Advances or any other amounts due under this Agreement in respect of its LIBOR Rate Advances or its obligation to make
LIBOR Rate Advances (except for any net income taxes imposed on the overall net income of any Lender or its Lending Office by a Governmental Authority in a jurisdiction with which such Lender has a
present or former connection unrelated to the transactions contemplated by the Transaction Documents) or imposes taxes or reserves in respect of the unutilized portion of any Lender's Commitment,
which in each case occurred as a result of the execution and delivery of this Agreement by such Lender; or

shall
impose, modify or deem applicable any reserve, liquidity, cash margin, special deposit, deposit insurance or assessment or other regulatory or similar requirement (including,
without limitation, any such requirement imposed by the Board of Governors, but excluding, with respect to any LIBOR Rate Advance, any such requirement included in an applicable LIBOR Reserve
Percentage) against assets of, deposits with or for the account of, or credit extended by, any Lender (or its Lending Office) or shall impose on any Lender (or its Lending Office) or on the London
interbank market any other condition affecting its LIBOR Rate Advances, Notes, Commitments or its obligation to make LIBOR Rate

14

---

Advances, which in each case would not have occurred but for execution and delivery of this Agreement by such Lender;

and
the result of any of the foregoing is to increase the cost to any Lender (or its Lending Office) of making or maintaining any LIBOR Rate Advance or to reduce the amount of any sum received or
receivable by any Lender (or its Lending Office) under this Agreement or under its Notes, with respect thereto or to cause that Lender to make any payment or forego any interest, fees or other return
on, or calculated by reference to any sum received or receivable by that Lender under this Agreement or Note, as the case may be, by an amount deemed by any Lender, acting reasonably, to be material,
such Lender shall promptly notify the Borrower and the Administrative Agent of such event and promptly deliver to the Borrower and the Administrative Agent a certificate setting forth in reasonable
detail the amount of that increased cost actually imposed or assessed or that reduction, payment or foregone interest, fees or other return and the basis for the determination of that amount. The
determinations of that Lender in such certificate shall be conclusive and binding for all purposes, absent manifest error. Within ten (10) days after demand by that Lender (with a copy to the
Borrower and the Administrative Agent), the Borrower shall pay to that Lender the amount shown as due on any such certificate.

Additional Interest.In the event that any Lender shall determine (which determination shall be conclusive and binding for
all purposes, absent manifest error) at any time that it is required to maintain reserves in respect of LIBOR Rate Advances during any period during which the principal amount of any LIBOR Rate
Advance is outstanding (each such period, for such Lender, a "LIBOR Reserve Period"), but only in respect of any period during which any reserve shall
actually be maintained by such Lender for its LIBOR Rate Advances as a result of a reserve requirement applicable to it pursuant to regulations of the Board of Governors of the Federal Reserve System
in connection with LIBOR Rate Advances, then such Lender shall promptly give notice to the Borrower
and the Administrative Agent of such determination, and the Borrower shall directly pay to such Lender additional interest on the unpaid principal amount of such LIBOR Rate Advance during such LIBOR
Reserve Period at a rate per annum which shall, during each monthly period applicable to such LIBOR Rate Advance, be the amount by which (x) the LIBOR Rate for such monthly period divided (and
rounded upward, if necessary, to the next whole multiple of 1/100 of 1%) by a percentage equal to 100% minus the then stated maximum rate of all reserve requirements (including, without
limitation, any marginal, emergency, supplemental, special or other reserves) applicable to such Lender in respect of LIBOR Rate Advances exceed (y) the LIBOR Rate for such monthly period. Any
Lender so requesting compensation shall furnish along with such notice a certificate setting forth in reasonable detail the cost actually incurred (or, if such calculation is impractical, reasonable
estimate of such cost) to maintain such reserves and the basis for the determination of that compensation. The determinations of the Lender in such certificate shall be binding and conclusive for all
purposes, absent manifest error. Additional interest payable pursuant to the immediately preceding sentence shall be paid by the Borrower at the time that it is otherwise required to pay interest in
respect of such LIBOR Rate Advance or, if later demanded by any Lender, within ten (10) days after such demand. Each Lender agrees that, if it gives notice to the Borrower and the
Administrative Agent of the existence of a LIBOR Reserve Period, it shall promptly notify the Borrower and the Administrative Agent of any termination thereof, at which time the Borrower shall cease
to be obligated to pay additional interest to such Lender pursuant to the first sentence of this paragraph until such time, if any, as a subsequent LIBOR Reserve Period shall occur.

Capital Adequacy.If (i) the adoption after the date hereof of any generally applicable Law regarding capital adequacy
(including, without limitation, a requirement which affects a Lender's (or any Person controlling such Lender) allocation of capital resources to its obligation in respect of that Lender's obligations
hereunder), (ii) any change after the date hereof in any such existing law or in the interpretation or administration thereof by any applicable Governmental Authority charged with the
interpretation or administration thereof or (iii) compliance by any Lender (or any Person controlling

15

---

such Lender) with any generally applicable request or directive regarding capital adequacy (whether or not having the force of law) of any such Governmental Authority has or would have the effect of
reducing the rate of return on any Lender's (or any Person controlling such Lender) capital as a consequence of any Advance to a level below that which such Lender (or any Person controlling such
Lender) could have achieved but for such adoption, change or compliance by an amount deemed by such Lender (or any Person controlling such Lender), acting reasonably, to be material, then within ten
(10) days after delivery by such Lender to the Borrower and the Administrative Agent of a certificate setting forth in reasonable detail the amount of such reduced return and the basis for the
determination of such amount (which certificate shall be binding and conclusive for all purposes, absent manifest error), the Borrower shall pay to such Lender such additional amount or amounts as
will compensate such Lender (or any Person controlling such Lender) for that amount of reduced return.

Claims.Each Lender will promptly notify the Borrower and the Administrative Agent of any event of which it has knowledge,
occurring after the date hereof, which will entitle any Lender to compensation pursuant to this Section 4.03 and will designate a different Lending Office if such designation will avoid the
need for, or reduce the amount of, such compensation and will not, in the sole judgment of such Lender, be otherwise disadvantageous to such Lender;provided,
however,that the Borrower shall not be obligated to compensate any Lender pursuant to this Section 4.03 for any costs incurred by such Lender more than 90 days
before the date such Lender notifies the Borrower of such event.

Illegality.If any Requirement of Law, or any change therein, or any change in the interpretation or administration thereof
by any Governmental Authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender (or its Lending Office) with any request,
directive or assertion, applicable to such Lender (whether or not having the force of law) of any such Governmental Authority, central bank or comparable agency shall make it unlawful or impossible
for any Lender (or its Lending Office) to make, maintain or fund LIBOR Rate Advances and such Lender shall so notify the Administrative Agent, the Administrative Agent shall forthwith give notice
thereof to the other Lenders and the Borrower whereupon until such Lender notifies the Borrower and the Administrative Agent that the circumstances giving rise to such suspension no longer exist, the
obligation of such Lender to make LIBOR Rate Advances, or to convert outstanding Advances into LIBOR Rate Advances, shall be suspended;provided,that
such Lender will designate a different Lending Office if such designation will permit the making of LIBOR Rate Advances and will not, in the sole judgment of such Lender, be otherwise disadvantageous
to such Lender. In the event that the making of LIBOR Rate Advances is suspended, as a result of the circumstances described in this Section 4.04, the affected Lender agrees to accept, in lieu
thereof, the conversion of the interest rate on such LIBOR Rate Advance to the Base Rate.

Basis for Determining Interest Rate Inadequate or Unfair.If on or prior to the first day of the Interest Period for any
LIBOR Rate Advance:



the
Administrative Agent shall forthwith give notice thereof (which notice shall describe in reasonable detail the basis for such determination) to the Borrower and each Lender, whereupon until the
Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such suspension no longer exist, (i) the obligations of the Lenders to make LIBOR Rate Advances,
or to

16

---

convert outstanding Advances into LIBOR Rate Advances, shall be suspended and (ii) each outstanding LIBOR Rate Advance shall be converted into a Base Rate Advance on the last day of the
Interest Period applicable thereto;provided, that any Lender making a claim pursuant to clause (b) above will designate a different Lending
Office if such designation will permit the making of LIBOR Rate Advances and will not, in the sole judgment of such Lender, be otherwise disadvantageous to such Lender.

Assignment.If the Borrower so requests from and after notice to the Borrower of any compensation due to any Lender under
Section 4.03 or 4.10 or the suspension of any Lender from the making of LIBOR Rate Advances under Section 4.04 or 4.05, the Administrative Agent shall arrange an assignment of such
Lender's proportionate share of the Total Commitments to an assignee selected by the Borrower (and reasonably acceptable to the Administrative Agent) subject to the provisions below, and such
assigning Lender hereby consents to any such assignment. Any assignment or transfer made by a Lender pursuant to this Section 4.06 shall satisfy the following conditions: (i) the
Borrower shall promptly pay when due all reasonable fees and expenses of such Lender incurred or to be incurred in connection with such transfer or assignment and (ii) any assignment of all or
part of the Total Commitments shall be made without recourse, representation or warranty (other than the representation or warranty that the assignor is the legal and beneficial owner of the interest
being assigned, free and clear of any adverse claim), and the Assignee shall pay to the Administrative Agent for the account of the assigning Lender in immediately available funds all amounts
outstanding or payable under this Agreement and any other Loan Document to each Lender assigning its interest in the Total Commitments;provided,
however,that assignment documentation in form and substance as set forth inExhibit 10.07(a)hereto shall be deemed
acceptable.

Breakage Costs.If the Borrower for any reason, including without limitation any prepayment pursuant to Section 4.02
or an acceleration of maturity of the Advances pursuant to Section 8.01, makes any payment of principal with respect to any LIBOR Rate Advance on any day other than the last day of an Interest
Period applicable thereto, fails to borrow, prepay or convert any LIBOR Rate Advance after notice has been given to the Lenders in accordance with the terms hereof, or fails to make a payment or a
prepayment in the manner and at the time specified in this Agreement, the Borrower shall promptly reimburse any Lender upon demand for any resulting loss, cost or expense incurred by it, including,
without limitation, any loss, cost or expense actually incurred in obtaining, liquidating or employing deposits from third parties. Without limiting the foregoing, the Borrower shall indemnify each
Lender against any direct loss, cost or expense that any Lender may sustain or incur as a consequence of any event described in the preceding sentence, including, but not limited to, any interest,
premium or penalty paid by any Lender to lenders of funds borrowed by it or deposited with it for the purpose of making or maintaining such LIBOR Rate Advance. A certificate as to the amount of any
such loss, cost or expense in reasonable detail (specifying the basis of such loss or expense) shall be promptly submitted by such Lender to the Borrower (with copies to the Administrative Agent) and
shall be binding and conclusive for all purposes, absent manifest error.

Sharing of Payments, etc.If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any
right of set-off, or otherwise) on account of the Advances owing to it in excess of its ratable share of payments on account of the Advances obtained by all the Lenders, such Lender shall
transfer such portions of such excess amount to the Administrative Agent for the account of the other Lenders as shall be necessary to cause all Lenders to share ratably in such excess amount. As used
herein, the terms ratable and nonratable shall be determined by reference to the respective Percentages of the Lenders.

17

---



The Borrower agrees to pay to the Administrative Agent for the account of each Lender a commitment fee on the average daily unused amount of such Lender's Project
Commitment, Working Capital Commitment and LC Commitment from the Closing Date, in the case of each Lender initially a party hereto, and from the effective date specified in the Lender Assignment
pursuant to which it became a Lender, in the case of each assignee of such Lender which becomes a Lender in accordance with the terms of this Agreement, until the Maturity Date or until such time as
the commitment is cancelled at the rate of 0.375% per annum, payable quarterly in arrears on each Payment Date, commencing on the first such date to occur following the Closing.

The
Borrower further agrees to pay to the Administrative Agent for the account of the LC Issuers a letter of credit fee on the aggregate Stated Amount of all outstanding Letters of
Credit (as reduced by drawings thereunder and scheduled reductions in the amount thereof) from the date of issuance of each Letter of Credit, until the Expiration Dates thereof at the rate equal to
the then Applicable Margin for LIBOR Rate Advances payable quarterly in arrears on each Payment Date, commencing on the first such date to occur following the initial issuance of any Letter of Credit,
with final payment on the final Expiration Date of any Letter of Credit.

The
Borrower further agrees to pay (i) the Lead Arrangers, an arrangement fee, (ii) the Administrative Agent, an annual administration fee and (iii) each LC Issuer,
a fronting fee, in the amounts and at the times specified in the Fee Letter.

The
Borrower further agrees to pay for the account of each LC Issuer, such additional nominal administrative fees and charges (including cable charges) as are generally associated with
letters of credit, in accordance with such LC Issuer's standard internal charge guidelines.



Any and all payments to any Lender, each LC Issuer, the Administrative Agent or the Collateral Agent (each such Lender, LC Issuer, Administrative Agent or
Collateral Agent, a "Payee") by or on behalf of the Borrower hereunder or under any other Transaction Document shall be made free and clear of and
without reduction or withholding for any and all present or future taxes, duties, levies, imposts, deductions, charges or withholdings, and any and all interest, penalties, and other liabilities
imposed with respect thereto, imposed by or on behalf of any Governmental Authority, excluding (x) any net income taxes (or franchise or similar taxes imposed in lieu of net income taxes)
imposed on a Payee's overall net income, or (y) other taxes imposed by a jurisdiction on such Payee to the extent such taxes would not have been imposed but for a present or former connection
between such Payee and such jurisdiction unrelated to the transactions contemplated by the Transaction Documents (all such taxes, duties, levies, imposts, deductions, charges, fees, withholdings,
interest, penalties and other liabilities,
collectively or individually, howsoever imposed and not excluded under clause (x) or (y) above being hereinafter referred to as "Covered
Taxes"). If the Borrower shall be required by law to withhold or deduct any Covered Taxes from or in respect of any sum payable hereunder or under any other Transaction
Document to any Payee, (i) the sum payable shall be increased by an amount as may be necessary so that after making all required withholdings (including withholdings applicable to additional
sums payable under this Section 4.10), such Payee receives an amount equal to the sum it would have received had no such reduction or withholding been made, (ii) the Borrower shall make
such reduction or withholding and (iii) the Borrower shall pay the full amount withheld to the relevant Governmental Authority or other authority in accordance with Requirement of Law. In
addition, the Borrower agrees to pay to the relevant Governmental Authority or other authority in accordance with Requirement of Law any present or future stamp, recording or documentary taxes, or any
other excise or property taxes, charges or similar levies that arise under the laws of any jurisdiction from any payment made hereunder or under any other Transaction Document or from the execution,
delivery,

18

---

registration, performance or otherwise with respect to this Agreement or any other Transaction Document. Each Lender that is not a United States person (within the meaning of
Section 7701(a)(30) of the Code) (a "Foreign Lender") shall make reasonable effort to notify the Borrower of any such taxes referred to in the
preceding sentence that are imposed in the jurisdiction in which such Foreign Lender is organized and, if its lending office (relating to transactions contemplated by the Transaction Documents) is
located outside the United States, in the jurisdiction in which such lending office is located, to the extent such Foreign Lender is aware of such taxes.

The
Borrower shall indemnify each relevant Payee, on an after-tax basis, for the full amount of Covered Taxes paid by such Payee or any liability arising therefrom or with
respect thereto (including, without limitation, reasonable attorneys' fees and expenses and other fees and expenses), whether or not such Covered Taxes were correctly or legally asserted by the
relevant Governmental Authority. Each Payee shall give notice to the relevant Borrower of the assertion of any claim against such Payee relating to such Payee's Covered Taxes as promptly as is
practicable after being notified of such assertion;provided,that any failure to notify the Borrower promptly of such assertion shall not relieve the
Borrower of its obligation under this Section 4.10,provided, however, that the Borrower shall not be obligated to make an indemnity payment to a
Payee in respect of penalties, interest and other similar liabilities attributable to any Covered Taxes (but shall not be relieved of the obligation to make an indemnity payment for the relevant
Covered Taxes) if (i) written demand therefor has not been made by such Payee within ninety (90) days from the date on which such Payee received written notice of the imposition of
Covered Taxes by the relevant taxing or Governmental Authority (except in the case where the ultimate amount of the Covered Taxes could not be determined within such 90-day period), but
only to the extent such penalties, interest and other similar liabilities are attributable to such failure or delay by the Payee in making such written demand or (ii) such penalties, interest
and other liabilities are solely attributable to the gross negligence or willful misconduct of the Payee or its Affiliates as determined by a court of competent jurisdiction. Payments by the Borrower
pursuant to this indemnification shall be made within twenty (20) days after the date the Payee makes written demand therefor (submitted through the Administrative Agent), which demand shall be
accompanied by a certificate describing in reasonable detail the basis thereof. A certificate as to the amount of such payment or liability prepared by such Payee, absent manifest error, shall be
final, conclusive and binding for all purposes.

As
soon as practicable after the date of any payment of Covered Taxes by the Borrower to the relevant Governmental Authority, the Borrower shall furnish to the Administrative Agent, who
will then forward
it to each affected Payee, the original or a certified copy of a receipt or other certificate issued by such Governmental Authority (or, if such copy or certificate is not available, any other
evidence of payment reasonably satisfactory to the Agent and such affected Payee or Payees) evidencing payment thereof and identifying the Covered Taxes paid. The Borrower shall compensate each Payee
for all reasonable losses and expenses sustained by such Payee as a result of any failure by the Borrower to so furnish such original or copy of such receipt or certificate.

19

---

Each Payee shall, (i) on the date such Payee becomes a party to this Agreement and (ii) before expiration of a previously delivered form, certification or document, from
time to time within 30 days after the reasonable written request of the relevant Borrower, provide to the Borrower two (2) copies, appropriately completed, of any form, document or other
certification necessary for such Payee to be exempt from, or entitled to a reduced rate of, Covered Taxes on payments pursuant to this Agreement or any other Transaction Document (including, in the
case of each Foreign Lender, an IRS Form W-8BEN or W-8ECI, as applicable, plus, in the case of a Foreign Lender claiming a portfolio interest exemption, a certificate as
to its non-bank status (in the form attached hereto asExhibit 4.10(d))) and such additional statements and forms as may be
reasonably requested by the Borrower from time to time;provided,however, that no Payee shall have any
obligation to provide any form, document or other certification if (i) the Payee is not entitled under Requirement of Law to provide such form, document or other certification or
(ii) the provision of such form, document or other certification would prejudice the interests of such Payee or its Affiliates (as reasonably determined by such Payee in its reasonable
judgment).

Notwithstanding
anything to the contrary in this Section 4.10 or any other provision of this Agreement, the Borrower shall not be required to pay any Covered Taxes to or on behalf
of any Payee to the extent that such Payee shall fail to comply with the requirements of Section 4.10(d) and, as a result of such failure, the Borrower is required by law to withhold Covered
Taxes from any payment to be made to or for the benefit of such Payee.

If
a Payee receives a refund of any Covered Tax from the jurisdiction imposing such tax, for which Covered Tax a payment has been made by the Borrower pursuant to this
Section 4.10 which refund in the reasonable judgment of such Payee is allocable to such payment by the Borrower made under this Section 4.10, the amount of such refund, net of all
out-of-pocket or other expenses (including any taxes on a refund or on interest received or credited) such Payee reasonably determines to have been incurred in connection with
obtaining such refund, shall be paid over to the Borrower;provided,however, that the Borrower, upon
the request of such Payee, agrees to repay the amount paid over to the Borrower (plus penalties, interest and other charges) to such Payee in the event such Payee is required to repay such refund with
respect to which a payment was made by such Payee to the Borrower. Notwithstanding anything to the contrary in this Section 4.10, such Payee shall have no obligation to cooperate with respect
to any contest (or continue to cooperate with respect to any contest), or seek or claim any refund, if such Payee reasonably determines that its interests would be adversely affected by so cooperating
(or continuing to cooperate) or by seeking or claiming any such refund.

If
the Borrower is required to pay additional amounts to or for the account of any Payee pursuant to this Section 4.10, then such Payee shall, at the request of the Borrower,
change the jurisdiction of its
applicable lending office if such change (i) will eliminate or reduce any such Covered Taxes which may thereafter accrue, and (ii) in such Payee's sole discretion, is determined not to
be otherwise disadvantageous to such Payee,provided, that the fees, charges, costs and expenses that are related to such change shall be borne by the
Borrower (and the mere existence of such expenses, fees or costs shall not be deemed to be disadvantageous to the Payee). Further, each Lender will consider in good faith any reasonable requests by
the Borrower to take actions to reduce or eliminate any Covered Taxes that are indemnifiable hereunder, but no Lender shall be obligated to take any such action that it determines in its sole

THE ADMINISTRATIVE AGENT AND THE TECHNICAL COMMITTEE

Authorization and Action.Each Lender hereby appoints and authorizes the Administrative Agent to take such action as agent on
its behalf and to exercise such powers under this Agreement as are delegated to the Administrative Agent by the terms hereof, together with such powers as are reasonably incidental thereto. As to any
matters not expressly provided for by any Loan Document (including enforcement thereof or collection thereunder), the Administrative Agent shall not be required to exercise any discretion or take any
action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Required Lenders or, if required by
the terms hereof, all Lenders, and such instructions shall be binding upon all Lenders and the LC Issuers;provided, however, that the Administrative
Agent shall not be required to take any action which exposes the Administrative Agent to personal liability or which is contrary to this Agreement or applicable Law. The Administrative Agent agrees to
deliver promptly to each Lender notice of each notice given to it by the Borrower pursuant to the terms of this Agreement or by any Project Company under the terms of the Project Company Guarantee.

Agent's Reliance, etc.Neither the Administrative Agent nor any of its directors, officers, agents or employees shall be
liable for any action taken or omitted to be taken by it or them under or in connection with any Loan Document, except for its or their own gross negligence or willful misconduct as found by a court
of competent jurisdiction. Without limitation of the generality of the foregoing, the Administrative Agent: (a) may treat the payee of any Note as the holder thereof until the Administrative
Agent receives and accepts a Lender Assignment or other assignment or transfer documentation entered into by the Lender which is the payee of such Note, as assignor or transferor, and an assignee, as
assignee or transferee, as provided in Section 10.07; (b) may consult with legal counsel (including counsel for the Borrower), independent public accountants and other experts selected
by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (c) makes no warranty or
representation to any Lender and shall not be responsible to any Lender for any statements, warranties or representations made in or in connection with any Loan Document; (d) shall not have any
duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or
conditions of any Loan Document on the part of the Borrower or to inspect the Project or any other property (including the books and records) of the Borrower; (e) shall not be responsible to
any Lender for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of any Transaction Document or any other instrument or document furnished pursuant hereto or
thereto; (f) shall incur no liability under or in respect of any Loan Document by acting upon any notice, consent, certificate or other instrument or writing (which may be by telegram,
telecopy, cable or telex) believed by it to be genuine and signed or sent by the proper party or parties and (g) shall not be charged with having knowledge of any Borrower Default, Borrower
Event of Default, Project Default or Project Event of Default unless provided with written notice thereof.

BNP PARIBAS and Affiliates.With respect to its Commitments and the Notes issued to it, BNP PARIBAS shall have the same
rights and powers under this Agreement as any other Lender and may exercise the same as though it were not the Administrative Agent; and the term
"Lender" or "Lenders" shall, unless otherwise expressly indicated, include BNP PARIBAS in its individual
capacity. BNP PARIBAS and its Affiliates may accept deposits from, lend money to, act as trustee under indentures of and generally engage in any kind of business with, the Borrower, each Member, any
of their respective Affiliates and any Person who may do business with or own securities of the Borrower, a Member or any Affiliate of the Borrower or of a Member, all as if BNP PARIBAS were not the
Administrative Agent and without any duty to account therefor to the Lenders.

Lender Credit Decision.Each Lender acknowledges that it has, independently and without reliance upon the Administrative
Agent or any other Lender and based on the financial information

43

---

referred to in Section 6.01(n) and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement.

Indemnification.The Lenders agree to indemnify the Administrative Agent (to the extent not reimbursed by the Borrower),
ratably according to the respective principal amounts of the Notes and the interests in the Letters of Credit then held by each of them (or if no Notes or Letters of Credit are at the time
outstanding, ratably according to the respective Percentages of the Lenders), from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against the Administrative Agent in any way relating to or arising out of this Agreement or
any action taken or omitted by the Administrative Agent under this Agreement;provided, that no Lender shall be liable for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Administrative Agent's gross negligence or willful misconduct as
found by a court of competent jurisdiction. Without limitation of the foregoing, each Lender agrees to reimburse the Administrative Agent promptly upon demand for its ratable share of any
out-of-pocket expenses (including counsel fees) incurred by the Administrative Agent in connection with the preparation, execution, delivery, administration, modification,
amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement to the extent that the
Administrative Agent is entitled to reimbursement for such expenses pursuant to Section 10.04 but is not reimbursed for such expenses by the Borrower, as the case may be.

Successor Administrative Agent.The Administrative Agent may resign at any time by giving written notice thereof to the
Lenders and the Borrower and may be removed at any time with or without cause by the Required Lenders, with any such resignation or removal to become effective only upon the appointment of a successor
Administrative Agent pursuant to this Section 9.06. Upon any such resignation or removal, the Required Lenders shall have the right to appoint a successor Administrative Agent, which shall be a
Lender or shall be another commercial bank, trust company or insurance company reasonably acceptable to the Borrower. If no successor Administrative Agent shall have been so appointed by the Required
Lenders, and shall have accepted such appointment, within 30 days after the retiring Administrative Agent's giving of notice of resignation or the Required Lenders' removal of the retiring
Administrative Agent, then the retiring Administrative Agent may, on behalf of the Lenders, appoint a successor Administrative Agent, which shall be a Lender or shall be another commercial bank or
trust company reasonably acceptable to the Borrower. Upon the acceptance of any appointment as Administrative Agent hereunder by a successor Administrative Agent and the execution and delivery by the
Borrower and the successor Administrative Agent of an agreement relating to the annual administration fees to be paid to the successor Administrative Agent as contemplated by Section 4.09(a) in
connection with its acting as Administrative Agent hereunder, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the
retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations under this Agreement. After any retiring Administrative Agent's resignation or
removal hereunder as Administrative Agent, the provisions of this Article IX shall continue to inure to its benefit as to any actions taken or omitted to be taken by it while it was
Administrative Agent under this Agreement.

Technical Committee.Each Lender hereby appoints and authorizes each of the Lead Arrangers, Credit Lyonnais, The Bank of Nova
Scotia and CoBank to act as its technical committee hereunder and under the other Loan Documents (the "Technical Committee") with such powers as are expressly delegated to the Technical Committee by
the terms of this Agreement and the other Loan Documents, together with such other powers as are reasonably incidental thereto and the power to appoint each of its additional members. The Technical
Committee shall not have any duties or responsibilities except those expressly set forth in this Agreement or in any other Loan Document, or be a trustee or a

44

---

fiduciary for any Lender. Notwithstanding anything to the contrary contained herein the Technical Committee shall not be required to take any action which is contrary to this Agreement or any other
Loan Documents or any Requirement of Law or exposes the Technical Committee to any liability. All decisions and determinations to be made by the Technical Committee hereunder and under the other Loan
Documents shall be made by consent of four of its five members. Borrower and each Lender hereby agrees that the protective provisions set forth in Sections 9.02 through 9.05 shall apply to and
protect, mutatis mutandis, each member of the Technical Committee and all determinations, decisions, actions or inactions taken or omitted to be taken by the Technical Committee. In the event that any
member of the Technical Committee at any time reduces its Commitment to less than $20,000,000, either the Borrower or the Administrative Agent may request the remaining members of the Technical
Committee to have such Lender removed. In the event that any member of the Technical Committee at any time ceases to be a Lender hereunder, is removed pursuant to the immediately preceding sentence or
otherwise resigns from the Technical Committee, then the Administrative Agent in consultation with the Borrower, shall appoint a Lender as a successor member to the Technical Committee; provided
(I) such Lender shall be a Lender with one of the ten largest Commitments at such time among the Lenders who are not then members of the Technical Committee and (ii) Borrower does not
disapprove of such Lender within five (5) Business Days of receipt of notice of such Lender's appointment to the Technical Committee.

by any Person by reason of or in connection with consummation of the transactions contemplated by the Commitment Letter dated December 7, 2000 among Sithe and the Lead Arrangers, the Loan

"Project Matters"), initiated by a Person other than the parties hereto, other than as a result of the Indemnified Person's gross negligence or willful
misconduct as found by a court of competent jurisdiction.

Without
limiting the generality of subsection (b), above, the Borrower further agrees to indemnify and hold harmless each Indemnified Person from and against any and all claims, losses,
liabilities, suits, obligations, fines, damages, judgments, penalties, charges, costs and expenses (including reasonable attorneys' fees and disbursements) (whether civil or criminal, arising under a
theory of negligence or strict liability, or otherwise) which may be imposed on, incurred or paid by or asserted against such Indemnified Person in connection with or resulting from any Environmental
Discharge relating to any Project (each, an "Environmental Matter" and collectively, the "Environmental
Matters") (I) at, upon or under any property of the Borrower or any of its Affiliates or any Project Party by or on behalf of any Person or (ii) by or on behalf
of the Borrower or any of its Affiliates or any Project Party at any time and in any place.

The
agreements of the Borrower in subsections (b) and (c), above, shall be in addition to any liabilities that the Borrower may otherwise have and shall apply whether or not a
Secured Party or any other Indemnified Person is a formal party to any lawsuit, claim or other proceeding. Solely for purposes of enforcing the agreements set forth in subsections (b) and (c),
above, the Borrower hereby consents, to the extent permitted by Law, to personal jurisdiction, service and venue in any court in which any claim or proceeding that relates to a Project Matter or an
Environmental Matter is brought against an Indemnified Person.

The
Borrower's obligations under this Section 10.04 shall survive the repayment of all amounts owing to the Lenders under the Notes and the termination of the Commitments. If and
to the extent that the obligations of the Borrower under this Section 10.04 are unenforceable for any reason, the Borrower agrees to make the maximum contribution to the payment and
satisfaction thereof which is permissible under applicable law.

The
Lenders agree to indemnify and hold harmless the LC Issuers, the Administrative Agent, the Collateral Agent, the Lead Arrangers and each member of the Technical Committee and their
respective officers, directors, employees, professional advisors and Affiliates, in their respective capacities as such (to the extent not reimbursed by the Borrower and without limiting the
obligation, if any, of the Borrower to do so), from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind whatsoever which may at any time be imposed on, incurred by or asserted against the Administrative Agent, any Lead Arranger or any member of the Technical Committee in its capacity as such in any
way relating to or
arising out of this Agreement or any Loan Document, or the performance of its duties and responsibilities hereunder or any action taken or omitted to be taken by the Administrative Agent, any Lead
Arranger or any member of the Technical Committee in its capacity as such under or in connection with any of the foregoing; provided, that the Lenders shall not be liable for the payment of any
portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements to the extent that any of the foregoing result in such Person's gross
negligence or willful misconduct as determined by a court of competent jurisdiction. The agreements in this Section 10.04(f) shall survive the payment or satisfaction in full of the
Obligations.

Upon (I) the occurrence and during the continuance of any Borrower Event of Default and (ii) the granting of the request or consent specified by
Section 8.01 to authorize the Administrative Agent to declare the Notes or amounts under the Letter of Credit due and payable pursuant to the provisions of Section 8.01, each Lender and
the LC Issuers is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand,
provisional or final) at any time held and other indebtedness at any time owing by such Lender or the LC Issuers to or for the credit or the account of the Borrower against any and all of the
obligations of the Borrower now or hereafter existing under this Agreement and the Notes held by such Lender or under the Letter of Credit, irrespective of whether or not such Lender or the LC Issuers
shall have made any demand under this Agreement or such Notes or under the Letter of Credit and although such obligations may be unmatured;provided,
however, that any amounts obtained by any Lender through its right of set-off shall be shared, ratably, by the Lenders. Each Lender each LC Issuer agrees promptly
to notify the Borrower after any such set-off and application made by such Lender or either LC Issuer,provided, that the failure to give
such notice shall not affect the validity of such set-off and application. The rights of each Lender and the LC Issuers under this Section 10.05 are in addition to other rights and
remedies (including other rights of set-off) which such Lender and the LC Issuers may have.

The
Borrower agrees that, to the extent permitted by applicable Law, it shall have no right of set-off or deduction in respect of its obligations hereunder, and that the
obligations of the Lenders hereunder are several and not joint. Nothing contained herein shall constitute a relinquishment or waiver of the Borrower's rights to any independent claim that the Borrower
may have against the Administrative Agent or any Lender for the Administrative Agent's or such Lender's, as the case may be, breach of this Agreement, gross negligence or willful misconduct as
determined by a court of competent jurisdiction, but no Lender shall be liable for the conduct of the Administrative Agent or any other Lender, and the Administrative Agent shall not be liable for the
conduct of any Lender.

Binding Effect.This Agreement shall become effective when it shall have been executed by the Borrower, the LC Issuers, the
Administrative Agent and each Lender whose name appears on the signature pages hereto and thereafter shall be binding upon and inure to the benefit of the Borrower,
the Administrative Agent, each Lender and the LC Issuers and their respective successors and assigns, except that the Borrower shall not have the right to assign its rights hereunder or any interest
herein without the prior written consent of all of the Lenders.



Assignments.Each Lender, with the consent of the Borrower (unless a Borrower Event of Default or a Material Borrower Default
has occurred and is continuing) and the consent of the Administrative Agent (which consents shall not be unreasonably withheld); may assign to one or more banks, financial institutions, or other
entities all or a portion of its rights and obligations under this Agreement and the other Loan Documents (including all or a portion of its Commitments, the Advances owing to it and the Note or Notes
held by it);provided, however, that (A) each such assignment shall be of a constant, and not a varying, percentage of all of the assigning
Lender's rights and obligations under this Agreement, (B) the amount of the Commitment of the assigning Lender being assigned pursuant to each such assignment (determined as of the date of the
Lender Assignment with respect to such assignment) shall in no event be less than the lesser of (x) the amount of such Lender's then remaining Commitment and (y) $10,000,000 (except in
the case of assignments between Lenders at the time already parties hereto), and (C) each assignee Lender shall comply with and be subject to the requirements of Section 4.10, including
submission of the forms required under Section 4.10(d), and (D) the parties to each such assignment shall execute and deliver to the Administrative Agent a duly completed Lender
Assignment, together with any Note or Notes subject to such assignment.

48

---

Notwithstanding the foregoing, any Lender in the ordinary course of its business and in accordance with Requirements of Law, may at any time assign to any Affiliate thereof without consent of the
Borrower or the Administrative Agent. Upon such execution, delivery, acceptance and recording, from and after the effective date specified in each Lender Assignment, (x) the assignee thereunder
shall be a party hereto and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such Lender Assignment, shall have the rights and obligations of a Lender
hereunder and (y) the Lender assignor thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Lender Assignment, relinquish its rights
and be released from its obligations under this Agreement (and, in the case of a Lender Assignment covering all or the remaining portion of an assigning Lender's rights and obligations under this
Agreement, such Lender shall cease to be a party hereto).

By
executing and delivering a Lender Assignment, the Lender assignor thereunder and the assignee thereunder confirm to and agree with each other and the other parties hereto as follows:
(I) other than as provided in such Lender Assignment, such assigning Lender makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or
representations made in or in connection with any Loan Document or the execution, legality, validity, enforceability, genuineness, sufficiency or value of any Loan Document or any other instrument or
document furnished pursuant thereto; (ii) such assigning Lender makes no representation or warranty and assumes no responsibility with respect to the financial condition of the Borrower or the
performance or observance by the
Borrower of any of its obligations under any Loan Document or any other instrument or document furnished pursuant thereto; (iii) such assignee confirms that it has received a copy of each Loan
Document, together with copies of the Closing Base Case and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Lender
Assignment; (iv) such assignee will, independently and without reliance upon the Administrative Agent, such assigning Lender or any other Lender and based on such documents and information as
it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under the Loan Documents; (v) such assignee appoints and authorizes the
Administrative Agent to take such action as agent on its behalf and to exercise such powers under the Loan Documents as are delegated to the Administrative Agent by the terms thereof, together with
such powers as are reasonably incidental thereto; and (vi) such assignee agrees that it will perform in accordance with their terms all of the obligations which by the terms of the Loan
Documents are required to be performed by it as a Lender.

Upon
its receipt of a Lender Assignment executed by an assigning Lender and an assignee, together with any Note or Notes subject to such assignment, the Administrative Agent shall, if
such Lender Assignment has been completed and is in substantially the form ofExhibit 10.07(a), (I) accept such Lender Assignment and
(ii) give prompt notice thereof to the Borrower. Within five Business Days after its receipt of such notice, the Borrower shall execute and deliver to the Administrative Agent in exchange for
each surrendered Note a new Note to such assignee in an amount equal to the Commitment assumed by it pursuant to such Lender Assignment and, if the assigning Lender has retained a Commitment
hereunder, a new Note or Notes to the assigning Lender in an aggregate amount equal to the Commitment retained by it hereunder. The aggregate principal amount of the new Note or Notes delivered to the
assignee and the assigning Lender shall be equal to the aggregate principal amount of such surrendered Note or Notes.

Participations.Each Lender may sell participations to one or more banks, financial institutions, or other entities in all or
a portion of its rights and obligations under the Loan Documents (including all or a portion of its Commitment, the Advances owing to it and the Note or Notes held by it); provided, however, that
(I) such Lender's obligations under this Agreement (including its Commitment to the Borrower hereunder) shall remain
unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) such Lender shall remain the holder

49

---

of any such Note for all purposes of this Agreement, (iv) the Borrower, the Administrative Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection
with such Lender's rights and obligations under this Agreement, (v) the participating banks, financial institutions or other entities shall be entitled to the cost protection provisions
contained in Sections 4.03(a), 4.03(c) and 4.06 only if the Lender from which such participant acquired its participation would have been entitled to such cost protection provisions had such Lender
not sold such participation hereunder, (vi) the participating banks, financial institutions or other entities shall not have any right to approve any amendment or waiver of any provision of any
Loan Document or to consent to the departure by the Borrower therefrom, unless the approval of all the Lenders is required for such amendment, waiver or consent, (viii) such participations
shall in no event be less than the lesser of (x) the amount of such Lender's then remaining Commitment and (y) $5,000,000 (except in the case of assignments between Lenders at the time
already parties hereto) and (ix) such Lender shall provide notice of such participation promptly thereafter.

Disclosure.Any Lender may, in connection with any assignment or participation or proposed assignment or participation
pursuant to this Section 10.07, disclose to the assignee or participant or proposed assignee or participant, any information relating to the Borrower furnished to such Lender by or on behalf of
the Borrower;provided, that prior to any such disclosure the assignee or participant or proposed assignee or participant shall agree, in accordance
with the terms of Section 10.08, to preserve the confidentiality of any Confidential Information received by it from such Lender.

Notwithstanding
anything to the contrary contained herein, any Lender (a "Granting Lender") may grant to a special purpose funding vehicle
(a "SPC"), identified as such in writing from time to time by the Granting Lender to the Administrative Agent and the Borrower, the option to provide to
the Borrower all or any part of any Advance that such Granting Lender would otherwise be obligated to make to the Borrower pursuant to this Agreement; provided, that (I) nothing herein shall
constitute a commitment by any SPC to make any Advance, (ii) if an SPC elects not to exercise such
option or otherwise fails to provide all or any part of such Advance, the Granting Lender shall be obligated to make such Advance pursuant to the terms hereof. The making of a Advance by an SPC
hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if, such Advance were made by such Granting Lender. Each party hereto hereby agrees that no SPC shall be liable
for any indemnity or similar payment obligation under this Agreement (all liability for which shall remain with the Granting Lender). In furtherance of the foregoing, each party hereto hereby agrees
(which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior
indebtedness of any SPC, it will not institute against, or join any other person in instituting against, such SPC any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings
under the laws of the United States or any State thereof. In addition, notwithstanding anything to the contrary contained in this Section 10.07(d), any SPC may (I) with notice to, but
without the prior written consent of, the Borrower and the Administrative Agent and without paying any processing fee therefor, assign all or a portion of its interest on any Advances to the Granting
Lender or to any financial institutions (consented to by the Borrower and Administrative Agent) providing liquidity and/or credit support to or for the account of such SPC to support the funding or
maintenance of Advances and (ii) disclose on a confidential basis any non-public information relating to its Advances to any rating agency, commercial paper dealer or provider of
any surety, guarantee or credit or liquidity enhancement to such SPC. This Section 10.07(d) may not be amended or modified without the written consent of the SPC, which consent may not be
unreasonably withheld.

Anything
in this Section 10.07 to the contrary notwithstanding, any Lender may assign and pledge all or any portion of its Loans and its Notes to any Federal Reserve Bank as
collateral security pursuant to Regulation A of the Board of Governors of the Federal Reserve System and any Operating

50

---

Circular issued by such Federal Reserve Bank. No such assignment shall release the assigning Lender from its obligations hereunder.



In connection with the negotiation and administration of this Agreement and the other Loan Documents, the Borrower has furnished and will from time to time
furnish to the Administrative Agent and the Lenders (each, a "Recipient") written information which is confidential (such information, other than any
such information which (I) was publicly available, or known to the Recipient otherwise than through other information previously provided by or on behalf of the Borrower and identified as being
confidential, at the time of disclosure, (ii) subsequently becomes publicly available other than through any act or omission by the Recipient or (iii) otherwise subsequently becomes
known to the Recipient other than through a Person whom the Recipient knows to be acting in confidence (or in violation of his or its obligations to the Borrower), being hereinafter referred to as
"Confidential Information"). The Recipient will maintain the confidentiality of any Confidential Information in accordance with such procedures as the
Recipient applies generally to information of that nature. It is understood, however, that the foregoing will not restrict the Recipient's ability to freely exchange such Confidential Information with
current or prospective participants in or assignees of the Recipient's position herein, but the Recipient's ability to so exchange Confidential Information shall be conditioned upon any such
prospective participant's or assignee's entering into an agreement for the benefit of the Borrower as to confidentiality substantially identical to this provision. It is further understood that the
foregoing will not prohibit the disclosure of any or all Confidential Information if and to the extent that such disclosure may be required or requested (I) by a regulatory agency or otherwise
in connection with an examination of the Recipient's records by appropriate authorities, (ii) pursuant to court order, subpoena or other legal process or in connection with any pending or
threatened litigation, (iii) otherwise as required by law or (iv) in order to protect its interests or its rights or remedies hereunder or under the other Loan Documents. In the event of
any required disclosure under clause (ii) or (iii), above, the Recipient agrees to use reasonable efforts to inform the Borrower as promptly as practicable before such disclosure so that the
Borrower may make such disclosure on behalf of any Lender or potential Lender, the Administrative Agent, any Secured Party, the Collateral Agent or any participant (to the extent that the Borrower is
not prohibited from doing so by Law) or seek a protective order or other appropriate remedy. To the extent that the Borrower does not make such disclosure on behalf of the Person required to make such
disclosure, the Person making such disclosure shall furnish only that portion of Confidential Information that it reasonably determines to be required by Law to be furnished and will exercise its
reasonable efforts to obtain reliable assurance that confidential treatment will be accorded such Confidential Information.

The
Borrower shall not use the name of the Administrative Agent, the Collateral Agent, the LC Issuers, the Depositary or any Secured Party in any advertisement without the express
written consent of such party, nor shall the Administrative Agent, the Collateral Agent, the Depositary or any Secured Party use the name of the Borrower in any advertisement (other than any
advertisement concerning the transactions contemplated by this Agreement) without the express written consent of the Borrower.

WAIVER OF JURY TRIAL; Limitation of Liability.(a) THE BORROWER, THE ADMINISTRATIVE AGENT AND THE LENDERS EACH HEREBY
IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR ANY OTHER INSTRUMENT OR DOCUMENT
DELIVERED HEREUNDER OR THEREUNDER.

(b)  No
claim shall be made by the Borrower or any Affilitate thereof against any Secured Party, or any of their Affiliates, directors, employees, attorneys, or agents for
any special, indirect, consequential, or punitive damages in respect of any breach or wrongful conduct (whether or not the

51

---

claim therefor is based on contract, tort, or duty imposed by law), in connection with, arising out of, or in any way related to the transactions contemplated by this Agreement or the other Loan
Documents or any act or omission or event occurring in connection therewith; and the Borrower and each Affiliate thereof hereby waives, releases, and agrees not to sue upon any such claim for any such
damages, whether or not accrued and whether or not known or suspected to exist in its favor.

Additional Collateral.The Lenders agree that any Collateral taken or received by or on behalf of the Lenders as security for
the Borrower's obligations under the Loan Documents will be held by the respective holder of such security not only for the benefit of the Lenders but also for the benefit of the other Secured
Parties, and that the proceeds of any such security (whether before, during or after the pendency of any proceeding against the Borrower under the Federal Bankruptcy Code) shall be applied in
accordance with the terms of the Depositary Agreement, it being understood that the Lenders may release or obtain reimbursement or other payments under the Loan Documents from all or any of such
Collateral at any time or from time to time without any consent of, notice to or payment to or for the account of, any Lender or the holder of any Note.

GOVERNING LAW, ETC.THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE
STATE OF NEW YORK, WITHOUT GIVING EFFECT TO THE CONFLICT OF LAWS PRINCIPLES THEREOF (EXCEPT SECTIONS 5-1401 AND 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW). THE BORROWER,

EXTENT IT MAY EFFECTIVELY DO SO, THE DEFENSE OF AN INCONVENIENT FORUM AND (IV) CONSENTS TO THE SERVICE OF PROCESS BY MAIL. A FINAL JUDGMENT IN ANY SUCH ACTION SHALL BE CONCLUSIVE AND MAY BE
ENFORCED IN OTHER JURISDICTIONS. NOTHING HEREIN SHALL AFFECT THE RIGHT OF ANY PARTY TO SERVE LEGAL PROCESS IN ANY MANNER PERMITTED BY LAW OR AFFECT ITS RIGHT TO BRING ANY ACTION IN ANY OTHER COURT.

Relation of the Parties; No Beneficiary.No term, provision or requirement, whether express or implied, of any Loan Document,
or actions taken or to be taken by any party thereunder, shall be construed to create a partnership, association, or joint venture between such parties or any of them. No term or provision of the Loan
Documents shall be construed to confer a benefit upon, or grant a right or privilege to, any Person other than the parties thereto.

No Recourse to Affiliates.Anything herein to the contrary notwithstanding, and except as expressly provided to the contrary
in any Loan Document, the payment of the Obligations by the Borrower and the performance of all other obligations of the Borrower and the Project Companies under this Agreement and the other Loan
Documents, and any certificate, notice, instrument or document delivered pursuant hereto or thereto are special obligations of the Borrower or the Project Companies, as the case may be, and, except
for Sithe New England's obligation in respect of the Equity Contribution Agreement, Sithe's obligations under the Equity Guarantee, the Sithe Undertaking and the Administrative Services Agreements,
Sithe Power Marketing's obligations under the Power Marketing Agreement, the SPM Security Agreement and SPM Depositary Agreement, Sithe New England Power Services under the Sithe Mystic Station O&M

had with respect thereto to) its members or any of its or their Affiliates, or any shareholder, partner, officer, director, employee, agent, attorney, consultant or controlling person of any such
member or Affiliate; except to the extent

relating to such member's or such Affiliate's express obligations under any Transaction Document, no action shall be brought against members or any Affiliates of the Borrower or its members, or any
shareholder, partner, officer, director, employee, agent, attorney, consultant or controlling person of any thereof as such, and any judicial proceedings a Lender, the Administrative Agent, the
Collateral Agent or the LC Issuers may institute against the Borrower shall be limited to seeking the preservation, enforcement, foreclosure or other sale or disposition of the Liens and security
interests now or at any time hereafter securing the repayment of the Advances and performance by the Borrower of its other covenants and obligations hereunder and under the other Loan Documents; and,
except to the extent relating to any member's or such Affiliate's express obligations under any Transaction Document, no judgment for any deficiency upon the obligations hereunder, or under the other
Loan Documents, shall be obtainable by the Administrative Agent, the Collateral Agent, the LC Issuers or any Lender against any of the members or their Affiliates or the Borrower's Affiliates or any
shareholder, partner, officer or director of any thereof. Nothing in this Section 10.14 shall be construed so as to prevent the Administrative Agent, the Collateral Agent, the LC Issuers or any
Lender from commencing any action, suit or proceeding with respect to the Borrower or causing legal papers to be served upon any member to the extent required to obtain jurisdiction over the Borrower.

Subject
to Section 4.12 of the Depositary Agreement, each payment and transfer to any Affiliate permitted under any Loan Document or Project Document, each Permitted Dividend and
each other payment or distribution by the Borrower or any Project Company that is not made in breach of its obligations under the Loan Documents shall be received by the Borrower's and the Project

holders of Obligations or other claims arising from any of the Loan Documents, including any and all avoidance and recovery rights and other claims of any type or description arising in favor of any
or all of the Lenders and any such other holders pursuant to any applicable law, all of which are hereby expressly and forever waived and released.
