and without regard to any other facts or circumstances. Subject to the
foregoing, except as provided in Section 19.2(d) hereof (relating to
distributions upon the dissolution of the Partnership), Section 11.8(b)
(relating to special allocations of Distributable Cash while the Tracking
Account Loan is outstanding), Section 11.12(b) (relating to special allocations
of Distributable Cash received in connection with any Niagara Mohawk
Proceeding), Section 11.12(d) (relating to special allocations of Distributable
Cash received in connection with the recovery of all or a portion of the
Casualty Insurance Claim Receivable) and Section 11.14 (relating to special
allocations of cash relating to TCC Net Revenues or TCC Revenue Shortfall),
Distributable Cash, if any, shall be distributed to the Partners in proportion
to their then existing Percentage Interests; PROVIDED, HOWEVER, that any
Distributable Cash otherwise allocable to one or more of the Partners pursuant
to this Section 10.1 but which is disbursed by the Partnership to a Curing
Credit Support Party as a result of, and to the extent of, the outstanding
balance of any amounts due to the Curing Credit Support Party on account of a
Credit Support Loan under the Credit Support Agreement, as required by Section
11.13 hereof, shall be treated for all purposes of this Agreement, including for
purposes of adjusting the respective Capital Accounts of the Partners pursuant
to Section 11.1(b), as having been distributed by the Partnership to the Partner
or Partners, as the case may be, that are Affiliated with the Credit Support
Defaulting Party.

     10.2 AMOUNTS WITHHELD.

  All amounts withheld pursuant to the Code or any state or local tax laws with
respect to any payment to the Partnership or to any Partner shall be treated as
amounts distributed pursuant to Sections 10.1 or 19.2(d) hereof for all purposes
of this Agreement. Amounts treated as distributed to any Person pursuant to such
Sections shall reduce the amount otherwise distributed or distributable to such
Person pursuant to such Sections.

     11. ALLOCATION OF PROFITS AND LOSSES.

     11.1 CAPITAL ACCOUNT.

  With respect to any Partner, a "Capital Account" shall be maintained for such
Partner in accordance with the following provisions:

          (a) To each Partner's Capital Account there shall be credited such
Partner's Capital Contributions, such Partner's distributive share of Profits
and any items in the nature of income or gain which are specially allocated
pursuant to Sections 11.5, 11.6, 11.8(a), 11.9(b), 11.12 and 11.14 hereof, and
the amount of any Partnership liabilities assumed by such Partner or which are
secured by any property distributed to such Partner as provided in Section
1.704-1(b)(2)(iv)(c) of the Regulations.

          (b) To each Partner's Capital Account there shall be debited the
amount of cash and the Gross Asset Value of any property distributed to such
Partner pursuant to any provision of this Agreement, such Partner's distributive
share of Losses and any items in the nature of expenses or losses which are
specially allocated pursuant to Sections 11.5, 11.6, 11.9(a), 11.12 and 11.14
hereof, and the amount of any liabilities of such Partner assumed by the
Partnership or which are secured by any property contributed by such Partner to
the Partnership as provided in Section 1.704-1(b)(2)(iv)(c) of the Regulations.

          (c) In the event all or a portion of an interest in the Partnership is
transferred in accordance with the terms of this Agreement, the transferee shall
succeed to the Capital Account of the transferor to the extent it relates to the
transferred interest.

          (d) In determining the amount of any Partnership liabilities for
purposes of this Section 11.1, there shall be taken into account Code Section
752(c) and any other applicable provisions of the Code and Regulations.

The foregoing provisions and the other provisions of this Agreement relating to
the maintenance of Capital Accounts are intended to comply with Regulations
Section 1.704-1(b), and shall be interpreted and applied in a manner consistent
with such Regulations. In the event the General Partner shall determine that it
is necessary to modify the manner in which the Capital Accounts, or any debits
or credits thereto (including, without limitation, debits or credits relating to
liabilities which are secured by contributions or distributed property or which
are assumed by the Partnership, General Partner, or Limited Partners), are
computed in order to comply with such Regulations, the General Partner may make
such modification; PROVIDED, that (i) it is not likely to have a material effect
on the amounts distributed to any Person pursuant to Section 19 hereof upon the
dissolution of the Partnership and (ii) prior to making any such modification
(A) the General Partner obtains the written consent of all Partners that may be
reasonably likely to be adversely affected by such modification or (B) if such
consent or consents cannot be obtained, the General Partner obtains a tax
opinion from a nationally recognized tax counsel with expertise in partnership
tax matters, which counsel is reasonably acceptable to the Partners holding a
majority in interest of the Percentage Interests, to the effect that the
proposed modifications of

<Page>

the General Partner are necessary to comply with the Regulations. The General
Partner also shall be entitled to make, subject to the foregoing proviso, (i)
any adjustments that are necessary or appropriate to maintain equality between
the Capital Accounts of the General Partner and Limited Partners and the amount
of Partnership capital reflected on the Partnership's balance sheet, as computed
for book purposes, in accordance with Regulations Section 1.704-1(b)(2)(iv)(q),
and (ii) any appropriate modifications in the event unanticipated events (for
example, the acquisition by the Partnership of oil or gas properties) might
otherwise cause this Agreement not to comply with Regulations Section
1.704-1(b).

     11.2 ALLOCATION OF LOSSES.

  Except as provided in Sections 11.5, 11.6, 11.8, 11.9, 11.12 and 11.14 hereof,
Losses of the Partnership for any taxable year shall be allocated to the
Partners in proportion to their then existing Percentage Interests. To the
extent that the allocation of a Loss to a Limited Partner would create or
increase an Adjusted Capital Account Deficit with respect to such Limited
Partner, however, such Loss shall instead be allocated to the General Partner.

     11.3 ALLOCATION OF PROFITS.

  Except as provided in Sections 11.5, 11.6, 11.8, 11.9, 11.12 and 11.14 hereof,
Profits of the Partnership for any taxable year shall be allocated to the
Partners in proportion to their then existing Percentage Interests.

     11.4 DEFICIT RESTORATION.

  Except as otherwise required by Applicable Laws or Sections 14.2(c) or 19.2(e)
of this Agreement, no Partner shall be required to contribute to any deficit of
the Partnership or to restore any debit Capital Account balance.

     11.5 REGULATORY ALLOCATIONS AND RELATED PROVISIONS.

  The following special allocations shall be made in the following order:

          (a) MINIMUM GAIN CHARGEBACK. Except as otherwise provided in Section
1.704-2(f) of the Regulations, notwithstanding any other provision of this
Section 11, if there is a net decrease in Partnership Minimum Gain during any
taxable year, each Partner shall be specially allocated items of Partnership
income and gain for such taxable year (and, if necessary, subsequent taxable
years) in an amount equal to such Person's share of the net decrease in
Partnership Minimum Gain, determined in accordance with Regulations Section
1.704-2(g). Allocations pursuant to the previous sentence shall be made in
proportion to the respective amounts required to be allocated to each Partner
pursuant thereto. The items to be so allocated shall be determined in accordance
with Sections 1.704-2(f)(6) and 1.704-2(j)(2) of the Regulations. This Section
11.5(a) is intended to comply with the minimum gain chargeback requirement in
Section 1.704-2(f) of the Regulations and shall be interpreted consistently
therewith.

<Page>

          (b) PARTNER MINIMUM GAIN CHARGEBACK. Except as otherwise provided in
Section 1.704-2(i)(4) of the Regulations, notwithstanding any other provision of
this Section 11.5, if there is a net decrease in Partner Nonrecourse Debt
Minimum Gain attributable to a Partner Nonrecourse Debt during any Partnership
taxable year, each Person who has a share of the Partner Nonrecourse Debt
Minimum Gain attributable to such Partner Nonrecourse Debt, determined in
accordance with Section 1.704-2(i)(5) of the Regulations, shall be specially
allocated items of Partnership income and gain for such Taxable year (and, if
necessary, subsequent taxable years) in an amount equal to such Person's share
of the net decrease in Partner Nonrecourse Debt Minimum Gain attributable to
such Partner Nonrecourse Debt, determined in accordance with Regulations Section
1.704-2(i)(4). Allocations pursuant to the previous sentence shall be made in
proportion to the respective amounts required to be allocated to each Partner
pursuant thereto. The items to be so allocated shall be determined in accordance
with Sections 1.704-2(i)(4) and 1.704-2(j)(2) of the Regulations. This Section
11.5(b) is intended to comply with the minimum gain chargeback requirement in
Section 1.704-2(i)(4) of the Regulations and shall be interpreted consistently
therewith.

          (c) QUALIFIED INCOME OFFSET. In the event any Partner unexpectedly
receives any adjustments, allocations, or distributions described in Section
1.704-1(b)(2)(ii)(d)(4), Section 1.704-1(b)(2)(ii)(d)(5) or Section
1.704-1(b)(2)(ii)(d)(6) of the Regulations, items of Partnership income and gain
shall be specially allocated to each such Partner in an amount and manner
sufficient to eliminate, to the extent required by the Regulations, the Adjusted
Capital Account Deficit of such Partner as quickly as possible; PROVIDED that an
allocation pursuant to this Section shall be made only if and to the extent that
such Partner would have an Adjusted Capital Account Deficit after all other
allocations provided for in this Section 11 have been tentatively made as if
this Section 11.5(c) were not in the Agreement.

          (d) GROSS INCOME ALLOCATION. In the event any Partner has a deficit
Capital Account at the end of any Partnership taxable year which is in excess of
the sum of (i) the amount such Partner is obligated to restore pursuant to any
provision of this Agreement, and (ii) the amount such Partner is deemed to be
obligated to restore pursuant to the penultimate sentences of Regulations
Sections 1.704-2(g)(1) and 1.704-2(i)(5), each such Partner shall be specially
allocated items of Partnership income and gain in the amount of such excess as
quickly as possible; PROVIDED that an allocation pursuant to this Section
11.5(d) shall be made only if and to the extent that such Partner would have a
deficit Capital Account in excess of such sum after all other allocations
provided for in this Section 11 have been made as if Section 11.5(c) hereof and
this Section 11.5(d) were not in the Agreement.

          (e) NONRECOURSE DEDUCTIONS. Nonrecourse Deductions for any taxable
year shall be allocated to the Partners in the same manner as Losses are
allocated pursuant to Section 11.2 above.

          (f) PARTNER NONRECOURSE DEDUCTIONS. Any Partner Nonrecourse Deductions
for any taxable year shall be specially allocated to the Partner who bears the
economic risk of loss with respect to the Partner Nonrecourse Debt to which such
Partner Nonrecourse Deductions are attributable in accordance with Regulations
Section 1.704-2(i)(1).

<Page>

          (g) SECTION 754 ADJUSTMENTS. To the extent an adjustment to the
adjusted tax basis of any Partnership asset pursuant to Code Section 734(b) or
Code Section 743(b) is required, pursuant to Regulations Section
1.704-1(b)(2)(iv)(m)(2) or Regulations Section 1.704-1(b)(2)(iv)(m)(4), to be
taken into account in determining Capital Accounts as the result of a
distribution to a Partner in complete liquidation of his interest in the
Partnership, the amount of such adjustment to Capital Accounts shall be treated
as an item of gain (if the adjustment increases the basis of the asset) or loss
(if the adjustment decreases such basis) and such gain or loss shall be
specially allocated to the Partners in accordance with their interests in the
Partnership in the event that Regulations Section 1.704-1(b)(2)(iv)(m)(2)
applies, or to the Partner to whom such distribution was made in the event that
Regulations Section 1.704-1(b)(2)(iv)(m)(4) applies.

     11.6 CURATIVE ALLOCATIONS.

  The allocations set forth in Sections 11.5(a), 11.5(b), 11.5(c), 11.5(d),
11.5(e), 11.5(f), and 11.5(g) hereof (the "Regulatory Allocations") are intended
to comply with certain requirements of the Regulations. It is the intent of the
Partners that, to the extent possible, all Regulatory Allocations shall be
offset either with other Regulatory Allocations or with special allocations of
other items of Partnership income, gain, loss or deduction pursuant to this
Section 11.6. Therefore, notwithstanding any other provision of this Article 11
(other than the Regulatory Allocations), the General Partner shall make such
offsetting special allocations of Partnership income, gain, loss or deduction in
whatever manner it determines to be appropriate so that, after such offsetting
allocations are made, each Partner's Capital Account balance is, to the extent
possible, equal to the Capital Account balance such Partner would have had if
the Regulatory Allocations were not part of the Agreement and all Partnership
items were allocated pursuant to Sections 11.2, 11.3, 11.8, 11.9, 11.12 and
11.14. In exercising its discretion under this Section 11.6, the General Partner
shall take into account future Regulatory Allocations under Sections 11.5(a) and
11.5(b) that, although not yet made, are likely to offset other Regulatory
Allocations previously made under Sections 11.5(e) and 11.5(f).

     11.7 TAX ALLOCATIONS.

  In accordance with Code Section 704(c) and the Regulations thereunder, income,
gain, loss, and deduction with respect to any property contributed to the
capital of the Partnership shall, solely for tax purposes, be allocated among
the Partners so as to take account of any variation between the Adjusted Basis
of such property to the Partnership for federal income tax purposes and its
initial Gross Asset Value. In the event the Gross Asset Value of any Partnership
asset is subject to adjustment, subsequent allocations of income, gain, loss,
and deduction with respect to such asset shall take account of any variation
between the Adjusted Basis of such asset for federal income tax purposes and its
Gross Asset Value in the same manner as under Code Section 704(c) and the
Regulations thereunder. Any elections or other decisions relating to such
allocations shall be made by the General Partner in any manner that reasonably
reflects the purpose and intention of this Agreement. Allocations pursuant to
this Section 11.7 are solely for purposes of federal, state, and local taxes and
shall not affect, or in any way be taken into account in computing, any Person's
Capital Account or share of Profits, Losses, other items, or

<Page>

distributions pursuant to any provision of this Agreement.

     11.8 SPECIAL ALLOCATIONS OF PROFIT AND LOSS AND DISTRIBUTABLE CASH WHILE
TRACKING ACCOUNT LOAN IS OUTSTANDING.

          (a) For each taxable year commencing with the first taxable year in
which principal payments on the Tracking Account Loan are paid by the
Partnership, there will be a special allocation of gross income otherwise
allocable to the Sithe Limited Partners away from such Sithe Limited Partners
and to Sithe/Independence, Inc. Such special allocation from each of the Sithe
Limited Partners to the General Partner will equal the lesser of:

               (i) the gross income otherwise allocable to such Sithe Limited
     Partner for such taxable year without regard to such special allocation;
     and

               (ii) the excess of (y) the sum of the Allocation Share of such
     Sithe Limited Partner for the current taxable year and each prior taxable
     year to which this Section 11.8(a) applies over (z) the cumulative amount
     of gross income specially allocated from such Sithe Limited Partner to the
     General Partner pursuant to this Section 11.8(a) for all prior taxable
     years.

The "Allocation Share" of a Sithe Limited Partner for each taxable year to which
this Section 11.8(a) applies shall be the product of its Tracking Account
Allocation Percentage for such taxable year multiplied by the amount of
principal payments made in such taxable year with respect to the Tracking
Account Loan.

          (b) (i) Throughout the period the Tracking Account Loan is
     outstanding, any Distributable Cash that would be distributed, but for this
     Section 11.8(b), to a Sithe Partner pursuant to Section 10.1 of this
     Agreement shall be distributed instead to Oswego Cogen pursuant to this
     Section 11.8(b)(i) if and to the extent that there shall exist a positive
     balance in the Special Distribution Account on such date. Such
     distributions shall be made to Oswego Cogen prior to, and with a priority
     over, the distribution of Distributable Cash to any of the Sithe Partners
     pursuant to Section 10.1; PROVIDED that any remaining Distributable Cash
     allocable to the Sithe Partners (after reflecting the special distribution
     described in the first sentence of this Section 11.8(b)(i)) shall be
     distributed among the Sithe Partners as provided in Section 10.1 of this
     Agreement.

               (ii) The Special Distribution Account on June 30, 2001 shall have
     a balance of zero. On each Special Distribution Account Determination Date,
     prior to the distribution of any Distributable Cash to the Sithe Partners,
     the Special Distribution Account shall be increased by an amount equal to
     the product of (A) the Percentage Interest of Oswego Cogen on such date and
     (B) the total amount of principal paid by the Partnership on or with
     respect to the Tracking Account Loan since the immediately preceding
     Special Distribution Account Determination Date, including any such
     principal paid on the

<Page>

     Special Distribution Account Determination Date. The Special Distribution
     Account shall be reduced (without duplication) by any amounts distributed
     to Oswego Cogen from time to time pursuant to Section 11.8(b)(i) of this
     Agreement. The Partnership shall furnish Oswego Cogen and each of the Sithe
     Partners a statement reflecting the outstanding balance of the Special
     Distribution Account, including all debits and credits thereto, from time
     to time but in all events as of each Special Distribution Account
     Determination Date.

               (iii) The amount of Distributable Cash distributed to Oswego
     Cogen pursuant to Section 10.1 of this Agreement shall not be reduced to
     any extent as a result of the payment or distribution of any amount
     pursuant to this Section 11.8(b) and the determination of the amount that
     is distributable to Oswego Cogen pursuant to Section 10.1 shall made
     without regard to the additional amount of Distributable Cash, if any, that
     is distributed to Oswego Cogen pursuant to this Section 11.8(b).

     11.9 CERTAIN SPECIAL ALLOCATIONS OF DEDUCTION AND INCOME RELATED TO PROJECT
TRACKING ACCOUNT DEDUCTION.

          (a) One hundred percent (100%) of the deduction resulting from fixing
the amount of the Tracking Account Loan shall be allocated specially to the
General Partner for the year in which the liability for such amount is fixed.
If, pursuant to a determination by the Internal Revenue Service or a court, the
Tracking Account Loan liability is reallocated from the General Partner in whole
or in part to any or all of the Sithe Limited Partners, then a portion or
portions of the aforementioned deduction corresponding to (and equal to) the
reallocated portion or portions of the Tracking Account Loan liability shall
likewise be reallocated to the Sithe Limited Partners, as the case may be. In
the event that part or all of said deduction is reallocated in the manner set
forth in the preceding sentence, the General Partner shall make corresponding
adjustments to the manner in which income is specially allocated under the
provisions of Section 11.8(a).

          (b) Any income realized by the Partnership pursuant to Section
61(a)(12) of the Code in connection with the satisfaction, reduction of
principal amount or other compromise of the Tracking Account Loan shall be
allocated one hundred percent (100%) to the General Partner; PROVIDED, HOWEVER,
that in the event the second sentence of Section 11.9(a) is applicable, any such
income shall be allocable to and among the Sithe Partners in proportion to the
manner in which the deduction described in Section 11.9(a) was allocable among
the Sithe Partners.

     11.10 COST RECOVERY RECAPTURE; ALLOCATION OF COST RECOVERY.

  Notwithstanding the provisions of Sections 11.2 and 11.3, if taxable gain to
be allocated pursuant to Section 11.3 includes gain treated as ordinary income
for income tax purposes because it is attributable to cost recovery recapture,
such gain so treated as ordinary income for federal income tax purposes shall be
allocated to and reported by the Partners in proportion to the aggregate of all
of their respective shares of cost recovery allocations, and the Partnership
shall keep records of such allocations. Such allocations of recapture shall be
merely a characterization

<Page>

of the net gains allocated pursuant to Section 11.3 hereof, and shall not affect
the amount of net gain allocated to a Partner.

     11.11 DISTRIBUTIONS AND ALLOCATIONS IN RESPECT OF TRANSFERRED INTERESTS.

  If all or any portion of any Interest is transferred during any accounting
period, Profits, Losses, each item thereof and all other items attributable to
such Interest for such period shall be divided and allocated between the
transferor and the transferee by accounting for their varying interests during
such period in accordance with the interim closing of the books method as
provided in Code Section 706(d). For this purpose, any deduction relating to the
establishment of the Tracking Account Loan has been allocated to the portion of
the taxable year of the Partnership ending immediately prior to the effective
time of the acquisition by Cogeneration National Corporation of its former
Interest in the Partnership. All distributions on or before the date of transfer
of such Interest in compliance with the provisions of this Agreement shall be
made to the transferor, and all distributions thereafter shall be made to the
transferee.

     11.12 SPECIAL ALLOCATION OF INCOME, LOSS AND DISTRIBUTABLE CASH FOR
PROCEEDS OF CERTAIN LITIGATION AND THE CASUALTY INSURANCE CLAIM RECEIVABLE.

          (a) During any taxable year in which the Partnership realizes any
gross income (or net gain) attributable to any Niagara Mohawk Proceeding, such
gross income (or net gain) shall be specially allocated to and among the Sithe
Partners in proportion to their respective Tracking Account Allocation
Percentages. No portion of such gross income (or net gain) shall be allocated to
Oswego Cogen.

          (b) Any amount received by the Partnership that is attributable to any
Niagara Mohawk Proceeding shall be distributed to the Sithe Partners in
proportion to their respective Tracking Account Allocation Percentages (subject
to refund if and to the extent the Partnership is required, pursuant to the
terms and conditions of any settlement or judgment of any Niagara Mohawk
Proceeding, to refund any such amounts so distributed to such Partners). In the
event that the Partnership is required, pursuant to the terms and conditions of
any settlement or judgment of any Niagara Mohawk Proceeding, to refund any
amounts, then any expense, loss or reduction in gross income attributable to
such refund shall be specially allocated to and among the Sithe Partners in
proportion to their respective Tracking Account Allocation Percentages.

          (c) During any taxable year in which the Partnership realizes gross
income, loss or deduction, if any, attributable to the Casualty Insurance Claim
Receivable, including the settlement or compromise thereof, such gross income,
loss or deduction shall be specially allocated to and among the Sithe Partners
in proportion to their respective Tracking Account Allocation Percentages. No
portion of such gross income, loss or deduction shall be allocated to Oswego
Cogen.

          (d) Any amount received by the Partnership that is attributable to the
proceeds of the recovery of all or a portion of the Casualty Insurance Claim
Receivable shall be distributed to the Sithe Partners in proportion to their
respective Tracking Account Allocation Percentages. The

<Page>

General Partner has informed Oswego Cogen that the Partnership's accrual or
receipt of the proceeds of the Casualty Insurance Claim Receivable shall not
result in a reduction in the depreciable basis of the Partnership's properties
to any material extent.

     11.13 DISBURSEMENTS IN REPAYMENT OF CREDIT SUPPORT LOANS.

  Notwithstanding any other provision of this Agreement, if on any date the
General Partner proposes to make a distribution of Distributable Cash pursuant
to Section 10.1 there shall exist any amount due and owing to a Curing Credit
Support Party with respect to a Credit Support Loan, the General Partner shall
(a) determine the aggregate amount of Distributable Cash tentatively allocable
to all of the Partner or Partners Affiliated with the applicable Credit Support
Defaulting Party, after reflecting any adjustment in such amount resulting from
the application of Sections 11.8(b)(i) and (ii) and 11.14(a), if applicable, but
before applying this Section 11.13, and (b) disburse to the Credit Support
Curing Party, rather than to the Partner or Partners Affiliated with the
applicable Credit Support Defaulting Party, an amount equal to the lesser of (i)
one hundred percent (100%) of the amount determined in (a) above or (ii) the
amount necessary to reduce the outstanding balance owed by the Credit Support
Defaulting Party under such Credit Support Loan to zero. The General Partner
shall cause the Partnership's books and records, including the Partners' Capital
Account balances, to account for any such cash payments to the Credit Support
Curing Party as having been disbursed to the Partner or Partners Affiliated with
the applicable Credit Support Defaulting Party in proportion to their respective
Percentage Interests, as reflected in the last proviso contained in Section
10.1, followed by the distribution or payment of funds by such Partners to the
Credit Support Defaulting Party, followed, in turn, by the payment by such
Credit Support Defaulting Party to the Credit Support Curing Party of an amount
equal to the cash disbursements received by such Credit Support Curing Party
pursuant to this Section 11.13 in repayment of such Credit Support Loan.

     11.14 SPECIAL DISTRIBUTIONS AND ALLOCATIONS WITH RESPECT TO EXCESS TCC
REVENUES AND TCC REVENUE SHORTFALLS.

          (a) If the General Partner proposes to make a distribution of
Distributable Cash pursuant to Section 10.1 of this Agreement and at such time
there shall exist a positive balance in the Sithe Partners TCC Distribution
Account or the Oswego Cogen TCC Distribution Account as of the last day of the
month immediately preceding the date of the distribution, then, subject to the
provisions of Section 11.8 and Section 11.12, Distributable Cash shall be
distributed to the Sithe Partners (in the case of a positive balance in the
Sithe Partners TCC Distribution Account) or Oswego Cogen (in the case of a
positive balance in the Oswego Cogen TCC Distribution Account) in an amount
equal to the lesser of (i) the amount of Distributable Cash available to be
distributed to Partners and (ii) the amount necessary to reduce said positive
balance to zero. Distributions made pursuant to this Section or Section
19.2(d)(iv) shall be referred to as "TCC Distributions." In the event that
Distributable Cash is distributed to the Sithe Partners pursuant to the
provisions of this Section 11.14(a), such Distributable Cash shall be allocated
and distributed among the Sithe Partners in proportion to the balances of their
respective subaccounts in the Sithe Partners TCC Distribution Account
(maintained and determined in accordance with the provisions of Section 1.83).
The distribution of a TCC Distribution to the Sithe Partners

<Page>

pursuant to this Section 11.14(a) shall not reduce to any extent the amount of
Distributable Cash distributed to the Sithe Partners pursuant to Section 10.1 of
this Agreement (but it shall instead reduce the amount of Distributable Cash
distributed to Oswego Cogen under Section 10.1), and the determination of the
amount that is distributable to the Sithe Partners pursuant to Section 10.1
shall be made without regard to the distribution of Distributable Cash to the
Sithe Partners pursuant to this Section 11.14(a). The distribution of a TCC
Distribution to Oswego Cogen pursuant to this Section 11.14(a) shall not reduce
to any extent the amount of Distributable Cash distributed to Oswego Cogen
pursuant to Section 10.1 of this Agreement (but it shall instead reduce the
amount of Distributable Cash distributed to the Sithe Partners under Section
10.1), and the determination of the amount that is distributable to Oswego Cogen
pursuant to Section 10.1 shall be made without regard to the distribution of
Distributable Cash to Oswego Cogen pursuant to this Section 11.14(a). At no time
shall the Sithe Partners be required to make any Capital Contribution to the
Partnership or any payment to Oswego Cogen on account of a negative balance in
the Sithe Partners TCC Distribution Account, nor shall Oswego Cogen be obligated
to make any Capital Contribution to the Partnership or any payment to the Sithe
Partners on account of a negative balance in the Oswego Cogen TCC Distribution
Account.

          (b) Commencing with the first taxable year in which, pursuant to
Section 11.14(a) or Section 19.2(d)(iv), either (i) the Sithe Partners receive
any distribution with respect to the Sithe Partners TCC Distribution Account or
(ii) Oswego Cogen receives any distribution with respect to the Oswego Cogen TCC
Distribution Account, gross income of the Partnership shall be specially
allocated to and among the Partners that received such distribution or
distributions in proportion to, and up to the amount of, the excess of (A) the
TCC Distributions received by each such Partner in the current taxable year and
all previous taxable years over (B) the cumulative amount of gross income
allocated to such Partner for prior taxable years pursuant to this Section
11.14(b). If gross income is specially allocated to the Sithe Partners pursuant
to this Section 11.14(b), the gross income otherwise allocable to Oswego Cogen
shall be reduced by the amount of such special allocation (and such special
allocation shall not reduce the amount of gross income otherwise allocable to
the Sithe Partners). If gross income is specially allocated to Oswego Cogen
pursuant to this Section 11.14(b), the gross income otherwise allocable to the

     properties or prospects of the Partnership;

               (xi) make any material press release or communication with the

     otherwise), results of operations, Business, properties or prospects of the
     Partnership;

               (xii) except as contemplated by Section 12.9 hereof, change the

               (ii) the Partners hereby expressly pre-approve and ratify any
     action taken or to be taken by the General Partner, without the consent of
     any other Partner, for the purpose of:

                    (1) seeking to amend the Indenture in order to permit Sithe
          Energies, Inc. to own, directly or indirectly, less than fifty-one

          entering into of contracts or agreements and events of similar import
          that are to be taken, or proposed to be taken, by such subsidiary (or
          any of its subsidiaries) shall be subject to the provisions of Section
          12.4(b) as if such subsidiary (or, if applicable, its subsidiary) were
          the Partnership;

                    (4) during the period commencing on July 1, 2001 and ending

     Partnership is a party and which have been entered into by the Partnership
     on or prior to July 1, 2001 or in compliance with the provisions of Section

     12.5 DUTIES AND OBLIGATIONS OF THE GENERAL PARTNER.

<Page>

          (a) The General Partner shall take all actions which may be necessary
or appropriate (i) for the continuation of the Partnership's valid existence as
a limited partnership under the laws of the State of Delaware (and of each other
jurisdiction in which such existence is necessary to protect the limited
liability of the Limited Partners or to enable the Partnership to conduct its
Business) and (ii) for the achievement of the Partnership's purposes in
accordance with the provisions of this Agreement and Applicable Laws.

          (b) The General Partner shall be responsible for the safekeeping and
use of all of the funds and assets of the Partnership, whether or not in its
immediate possession, or control, and shall not employ or permit another to
employ such funds or assets in any manner except for the benefit of the
Partnership.

          (c) The General Partner shall devote to the Partnership such time as
may be necessary for the proper performance of its duties hereunder.

          (d) The General Partner shall conduct the affairs of the Partnership
in the best interests of the Partnership and of the Partners, including the
safekeeping and use of all Partnership funds and assets for the benefit of the
Partnership.

     12.6 POWER OF ATTORNEY.

          (a) Each Limited Partner by its execution of this Agreement
irrevocably constitutes and appoints the General Partner as such Limited
Partner's true and lawful attorney and agent, with full power and authority in
such Limited Partner's name, place and stead, to execute, acknowledge, deliver,
file and record in the appropriate public offices: (i) all certificates or other
instruments (including, without limitation, counterparts of this Agreement) and
amendments thereto which the General Partner deems appropriate to qualify or
continue the Partnership as a limited partnership (or a partnership in which
special partners have limited liability) in the jurisdictions in which the
Partnership conducts its Business; (ii) all instruments and amendments thereto
which the General Partner deems appropriate to reflect any change or
modification of the Partnership or the admission of additional or substituted
Partners; (iii) all documents of conveyance and other instruments which the
General Partner deems appropriate to evidence and reflect any sales or transfer
by or the dissolution and termination of the Partnership; (iv) all consents to
transfers of Interests, to the admission of additional or Substituted Limited
Partners or to the withdrawal or reduction of any Person's invested capital; in
each case to the extent that such actions are authorized by the terms of this
Agreement; and (v) the execution of any or all of the documents reasonably
necessary to the conduct of the Business of the Partnership.

          (b) The foregoing grant of authority (i) is a special power of
attorney coupled with an interest in favor of the General Partner and as such
shall be irrevocable and shall survive the death or insanity (or, in the case of
a Limited Partner that is a corporation, association, partnership, joint venture
or trust, shall survive the merger, dissolution or other termination of its
existence) of a Limited Partner; (ii) may be exercised for a Limited Partner by
a facsimile signature of the General Partner or by listing the Limited Partner,
executing any instrument with a single signature of the General Partner acting
as attorney-in-fact for all of them, and (iii) shall

<Page>

survive the assignment by a Limited Partner of the whole or any portion of its
Interest, except that where the assignee of the whole thereof has furnished a
power of attorney and has been approved by the General Partner for admission to
the Partnership as a Substituted Limited Partner, this special power of attorney
shall survive such assignment for the sole purpose of enabling the General
Partner to execute, acknowledge and file any instrument necessary to effect such
substitution and shall thereafter terminate.

     12.7 INDEPENDENT ACTIVITIES.

  The Limited Partners and their respective Affiliates (other than the General
Partner), and any Affiliate of the General Partner, may, notwithstanding the
existence of this Agreement, engage in whatever activities they choose, whether
the same shall be competitive with the Partnership or otherwise, without having
or incurring any obligation to offer or disclose any interest in such activities
to the Partnership or any Partner. Neither this Agreement nor any activity
undertaken pursuant hereto shall prevent such Persons from engaging in any
activity, or require the General Partner to permit the Partnership or any
Partner to participate therein, and, as a material part of the consideration for
the General Partner's execution hereof and admission of the Limited Partners,
each of the Partners hereby waives, relinquishes and renounces any such right or
claim of participation in any other venture or activity engaged or participated
in by such Person(s), except pursuant to a written agreement signed by the
General Partner. It is specifically understood and agreed that Affiliates of the
General Partner may organize and participate as general partner in partnerships
which may engage in activities substantially identical to the activity engaged
in by this Partnership.

     12.8 EXEMPT WHOLESALE GENERATOR STATUS.

  Each of the Partners shall exercise their good faith efforts to cooperate and
take such actions as may be reasonably necessary to cause the Partnership to
obtain the status of an Exempt Wholesale Generator pursuant to the rules and
regulations of the Federal Energy Regulatory Commission; PROVIDED that no
Partner shall be obligated to take any action to cause the Partnership to obtain
Exempt Wholesale Generator status pursuant to this Section 12.8 if, in the
reasonable judgment of such Partner, such action could reasonably be expected to
cause a material adverse change in the condition (financial or otherwise),
results of operations, Business, properties or prospects of the Partnership.

     12.9 AMENDED AND RESTATED OPERATIONS AND MAINTENANCE AGREEMENT;
RESTRICTIONS ON CHANGE OF CONTROL OF OPERATOR; ADMINISTRATIVE SERVICES
AGREEMENT.

          (a) The General Partner and the Limited Partners acknowledge and agree
that the General Partner currently is in negotiations, on behalf of the
Partnership, with the Operator to amend and restate the Operations and
Maintenance Agreement (such new agreement, the "Second Amended and Restated
Operations and Maintenance Agreement"). The General Partner shall use
commercially reasonable efforts to promptly conclude the negotiations of such
agreement containing terms substantially in accordance with the proposed terms
set forth in Exhibit B hereto. If, following the execution and delivery of the
Second Amended and Restated

<Page>

Operations and Maintenance Agreement, a "Change of Control" shall have occurred
(as such term is described in the proposed terms set forth in Exhibit B, which
provisions shall be reflected in the Second Amended and Restated Operations and
Maintenance Agreement), the General Partner shall furnish to the Operator a
notice that the Partnership desires the Second Amended and Restated Operations
and Maintenance Agreement to continue in effect despite the occurrence of such
Change of Control if, and only if, directed to do so in writing by Oswego Cogen.
The General Partner shall promptly notify Oswego Cogen of the occurrence of any
such Change of Control. The Partners acknowledge that the exercise of the
Partnership's and the Operator's respective rights and obligations under the
Second Amended and Restated Operations and Maintenance Agreement shall be
subject to the Indenture, Security Agreement and the consent previously executed
by the Operator with the Collateral Agent.

that the General Partner currently is in negotiations, on behalf of the
Partnership, with Sithe Energies Power Services, Inc. to conclude an agreement
(the "Administrative Services Agreement") for the provision by Sithe Energies
Power Services, Inc., as the Administrative Services Provider, of certain
administrative services to the Partnership. The General Partner shall use
commercially reasonable efforts to promptly conclude the negotiations of such
agreement containing terms substantially in accordance with the proposed terms
set forth in Exhibit C hereto.

     12.10 CERTAIN ACTIONS UPON THE OCCURRENCE OF AN EVENT OF LOSS; TECHNICAL
DISPUTES.

          (a) EVENTS OF LOSS. Notwithstanding Section 12.4, the Partners hereby
expressly pre-approve any action taken or to be taken by the General Partner for
the purpose of making any determination and certification pursuant to Section
6.10(c) of the Indenture following an Event of Loss; PROVIDED, that the
execution and delivery of any material contracts or agreements proposed by the
General Partner on behalf of the Partnership in connection with the
reconstruction or repair of the Project following an Event of Loss shall require
the General Partner to demonstrate, subject to confirmation by the Technical
Expert if requested by Oswego Cogen as provided in Section 12.10(b) below, that
the reconstruction or repair of the Project in accordance with such contracts or
agreements is commercially reasonable, taking into account the impact, if any,
on the Project's revenues and expenses and general market conditions at such
time.

          (b) TECHNICAL DISPUTES. In the event Oswego Cogen disputes any
determination of the General Partner pursuant to Section 12.10(a), such dispute
shall be deemed a "Technical Dispute" hereunder and Oswego Cogen shall be
entitled to notify the General Partner that it desires to refer such Technical
Dispute to a Technical Expert for resolution in accordance with the provisions
of Section 12.10(c) and (d). Notwithstanding the foregoing or Section 12.4(b) to
the contrary, in the event the Partnership receives Casualty Proceeds (as
defined in the Indenture) from any Event of Loss that do not exceed, in the
aggregate, $10,000,000, the Partners hereby expressly pre-approve any action
taken or to be taken by the General Partner for the purpose of reconstructing,
repairing or otherwise restoring any portion of the electric or steam generation
facilities at the Project following the occurrence of such Event of Loss and the
Technical Dispute provisions of Section 12.10(c) and (d) below shall not be
available to Oswego Cogen.

<Page>

          (c) DESIGNATION OF TECHNICAL EXPERT. Within ten (10) days following
receipt of a notice referring a Technical Dispute to a Technical Expert, the
representatives of the General Partner and Oswego Cogen shall confer in an
effort to agree upon a Technical Expert to hear the dispute. If such parties are
unable to agree upon the appointment of a Technical Expert then, at the end of
such ten (10) day period, each party shall, within five (5) days, notify the
other party in writing of its designation of three proposed Technical Experts.
Each party shall promptly strike two of the proposed Technical Experts
designated by the other party. The remaining two proposed Technical Experts
shall, within two (2) days, select one of them to hear the dispute; provided,
that if one of the parties still objects to the dispute being heard by such
selected Technical Expert, then, within two (2) days, such two proposed
Technical Experts shall select a third Technical Expert and such third Technical
Expert shall hear the dispute.

          (d) TECHNICAL DISPUTE PROCEDURES. The Technical Expert shall render a
decision resolving the matter within sixty (60) days of the date of his or her
selection as the Technical Expert. The decision of the Technical Expert shall be
in writing and shall be final and binding upon the parties and not subject to
appeal or review. The Partnership shall bear all costs and expenses of the
Technical Expert procedure and the Technical Expert shall not have the authority
to award costs or attorneys' fees to either party. The Technical Expert shall
resolve the Technical Dispute in accordance with the procedures set forth in the
Commercial Arbitration Rules of the American Arbitration Association, and such
decision may be confirmed and enforced in, and judgment upon the award entered
by, any federal or state court having jurisdiction over the parties.

     12.11 PROVISIONS AFFECTING THE TCC.

          (a) During the period commencing on July 1, 2001 and ending on
December 31, 2001, Oswego Cogen or an Affiliate thereof may, at its option,
undertake and commence on behalf of the Partnership a competitive auction or
substantially similar bid process designed to solicit competitive bid proposals
from creditworthy purchasers for the purchase or acquisition by any such
purchaser(s) of all of the TCC with the objective of locking in for the
Partnership an equal and fixed monthly revenue stream for the TCC (a "TCC
Transaction"). In the event that Oswego Cogen or an Affiliate thereof decides to
undertake and commence such auction or bid process pursuant to the immediately
preceding sentence, (i) Oswego Cogen shall, for so long as it (or its Affiliate)
continues such efforts, provide the General Partner with notice pursuant to
Section 24.10, on at least a weekly basis, of the likelihood for success and
proposed or expected timing of such auction or bid process and (ii) the General
Partner shall cooperate with Oswego Cogen (or its Affiliate, as the case may be)
in facilitating the consummation of the auction or bid process, taking into
account that such auction or bid process will be conducted on behalf of the
Partnership. The General Partner shall not take any action pursuant to Section
12.4(d)(ii)(4) that would reasonably be expected to interfere with Oswego
Cogen's (or its Affiliate's) right to secure a TCC Transaction for the
Partnership pursuant to this Section 12.11.

          (b) Oswego Cogen shall promptly submit, or cause to be promptly
submitted, to the General Partner the results of any auction or bid process and
the details of any proposed TCC Transaction following its receipt thereof.
Neither the General Partner nor the Partnership shall

<Page>

have any obligation to submit the proposed TCC Transaction to the Partners for
their approval or disapproval (as required pursuant to Section 12.4(b)(xiv)
hereof) and, if the Partners approve, to seek to effect such TCC Transaction
unless such TCC Transaction if consummated would: (i) commence no later than
April 1, 2002; (ii) have a scheduled expiration date of no earlier than December
31, 2008; (iii) obligate the purchaser (or purchasers) thereunder to pay to the
Partnership over the entire term of such TCC Transaction fixed, equal monthly
payments, with each such payment (or, if multiple purchasers, the aggregate
amount of such monthly payments) to be equal to or greater than the TCC Baseline
Net Revenue Amount (determined without regard to whether a particular month
comes within the TCC Allocation Period); (iv) be entered into with a purchaser
which has, or which is supported by a party which has, an investment grade
credit rating from a nationally recognized credit rating agency; (v) would
satisfy the conditions of Section 12.1(c), if applicable; and (vi) would require
the purchaser (or purchasers) to acquire all (and not merely a portion) of the
TCC through the scheduled expiration date of the TCC Transaction. If a TCC
Transaction proposed by Oswego Cogen (or its Affiliate, as the case may be)
satisfies the conditions immediately above, the General Partner shall use
commercially reasonable efforts, acting in good faith, to (i) timely submit the
TCC Transaction to the Partners for their approval or disapproval as required
pursuant to Section 12.4(b)(xiv) hereof and, if the Partners approve the TCC
Transaction, (ii) take such actions which may be reasonably necessary to
consummate such TCC Transaction. Oswego Cogen and each of the Sithe Partners
shall be free to approve or disapprove the proposed TCC Transaction pursuant to
the provisions of Section 12.4(b)(xiv) notwithstanding any other provision of
this Section 12.11.

          (c) Consummation of a proposed TCC Transaction as contemplated above
shall not limit or otherwise restrict the amount of income allocated to, or
Distributable Cash distributable to, the Sithe Partners or Oswego Cogen, as the
case may be, pursuant to Section 11.14 hereof; PROVIDED, HOWEVER, that for the
avoidance of doubt, the special allocations of gross income and Distributable
Cash provided in Section 11.14 shall terminate with respect to the period ending
December 31, 2005 despite the fact that the TCC Transaction may continue through
2008 or longer.

     13. INVESTMENT AND OPERATING RESTRICTIONS.

     13.1 TRANSFERS OF PROPERTY.

  The signature of the General Partner shall be sufficient to pass title to any
property owned by the Partnership or to execute any promissory notes, trust
deeds, mortgages or other instruments of hypothecation, and each of the Limited
Partners agrees that a copy of this Agreement, subject to appropriate
confidentiality protections, may be shown to the appropriate parties in order to
confirm the same, and further agrees that the signature of the General Partner
shall be sufficient to execute any documents necessary to effectuate this or any
other provision of this Agreement.

     13.2 RECEIPT OF FUNDS.

  If, at any time during the continuance of this Agreement, cash, bills or other
securities or evidence of indebtedness arising out of or in any manner connected
to this Partnership shall be

<Page>

received by a Limited Partner (except for distributions by the Partnership to a
Limited Partner as permitted by this Agreement), the same shall be brought to
the attention of the General Partner and shall be deposited promptly in a
banking institution or wherever the funds and profits of this Partnership are
held or shall be turned over to the General Partner.

     14. ADDITIONAL GENERAL PARTNER; REMOVAL OF A GENERAL PARTNER.

     14.1 ADDITIONAL GENERAL PARTNER.

  Persons may be admitted to the Partnership as additional General Partners with
the consent of the General Partner and all of the Limited Partners. The addition
of one or more General Partners shall not increase the total distributions or
allocations to the General Partners as a group.

     14.2 REMOVAL OF A GENERAL PARTNER.

          (a) Any General Partner may be removed as general partner, but not as
a Partner, upon a vote of the Limited Partners holding seventy-five percent
(75%) of the Interests in the Partnership that are not owned by Affiliates of
the General Partner, in the event that, pursuant to a final, non-appealable
judgment, it shall have been determined that the General Partner has committed
fraud or engaged in willful misconduct in connection with the Business of the
Partnership; PROVIDED, HOWEVER, that no removal shall be effective until a
replacement general partner is appointed pursuant to Section 14.2(b). Upon such
removal, the Interest of the General Partner as removed shall be converted into
an Interest as a Limited Partner.

          (b) Unless the General Partner and the Limited Partners otherwise
agree, if the last General Partner is removed as general partner pursuant to
Section 14.2(a), a replacement general partner shall be appointed with the
written approval of all of the Limited Partners which are not Affiliates of the
removed General Partner, such replacement general partner shall be deemed
admitted to the Partnership immediately prior to the removal of the predecessor
General Partner and such replacement general partner hereby is authorized to and
shall continue the Business of the Partnership. Any replacement general partner
appointed pursuant to this Section 14.2(b) shall either purchase a one percent
(1%) Percentage Interest in the Partnership for the fair market value thereof or
be assigned all or part of the Percentage Interest of one or more of the
consenting Limited Partners. No General Partner shall be admitted as such
pursuant to this Section 14.2(b) if the admission of such General Partner would
violate any of the limitations on transfer set forth in Sections 15.3(b) through
(e).

          (c) Any General Partner which is removed as a general partner of the
Partnership shall continue to remain liable as a general partner for all debts
and obligations of the Partnership incurred prior to or as a result of such
removal, but shall not have any liability for any debts and liabilities of the
Partnership incurred after such removal. Notwithstanding the foregoing,
following the removal of any General Partner, such General Partner shall remain
obligated, pursuant to Section 19.2(e) hereof, to restore any negative balance
existing in such General Partner's Capital Account upon the liquidation of the
Partnership or of such General Partner's interest in the Partnership; PROVIDED,
HOWEVER, that such obligation shall not exceed the deficit

<Page>

balance existing on the date of the conversion of such General Partner's
Interest as General Partner into an Interest as a Limited Partner.

     15. ASSIGNABILITY OF INTERESTS.

     15.1 TRANSFER OF LIMITED PARTNERS' INTEREST.

  Except as provided in this Section 15, the only restrictions on the assignment
or hypothecation of the Interests of the Limited Partners shall be that the
assignor shall first have obtained the written consent of all of the Partners;
PROVIDED, HOWEVER, that such consent shall not be unreasonably withheld,
conditioned or delayed. Any Limited Partner, however, shall be entitled, without
receiving the consent of the other Partners but subject to the provisions of
Sections 15.3 and 15.6, to transfer or hypothecate its Interest, without
relieving itself of liability hereunder, (i) as security for any financing, (ii)
to any of its Affiliates or (iii) in the case of the Sithe Partners, to Exelon
Corporation, a Pennsylvania corporation, or any Affiliates of Exelon
Corporation; PROVIDED, HOWEVER, that any such transfer does not have the
consequence described in clause (i) of the immediately following sentence.
Without limiting the rights of the Partners whose consent is required for a
proposed transfer by another Partner of its Interest, it shall not be
unreasonable for a Partner to withhold its consent if (i) such transfer would
result in a termination of the Partnership for federal income tax purposes
pursuant to Code Section 708 or (ii) such transfer is proposed to be made to a
Person (or an Affiliate thereof) that is an adverse litigant of the Partnership,
of any Partner or of any Affiliate of any Partner in any material litigation.

     15.2 RIGHT OF FIRST NEGOTIATION.

  In the event that a Limited Partner (hereafter, the "Selling Partner") desires
to make an assignment of all or a portion of its Interest to a Person other than
an Affiliate of the Selling Partner, the Selling Partner agrees to first
negotiate exclusively for a period of not less than thirty days with the Offeree
for the purchase by the Offeree or its designee of such Interest. For purposes
hereof, "Offeree" means either (1) Oswego Cogen, in the event the Selling
Partner is one of the Sithe Partners, or (2) Sithe Energies, Inc., in the event
the Selling Partner is Oswego Cogen. In the event that after such time period an
agreement cannot be reached between the Selling Partner and the Offeree, the
Selling Partner may proceed to assign its Interest to any other Person, subject
to the consent requirements of Section 15.1; PROVIDED, HOWEVER, that in the
event the Selling Partner fails to so assign its Interest within six months of
the date on which the Selling Partner and the Offeree fail to reach agreement,
the Selling Partner may not assign its Interest without once again complying
with the provisions of this Section 15.2. No Limited Partner shall transfer its
Interest to an Affiliate and then transfer ownership in such Affiliate to
another Person to avoid compliance with this Section 15.2. Notwithstanding the
foregoing, the right of first negotiation set forth in this Section 15.2 shall
not apply (i) to the transfer or assignment of all or a portion of the Interests
of Sithe/Independence, Inc., Sithe Energies, Inc., Sithe Energies U.S.A., Inc.,
Mitex, Inc. or Oswego Cogen to the extent necessary (and only to the extent
necessary) to prevent the Partnership from becoming a Person primarily engaged
in the generation or sale of electric power (other than electric power solely
from cogeneration facilities or small power production facilities), as defined
in 18 C.F.R. ss. 292.206, including a sale or

<Page>

transfer described in Section 15.4 or (ii) to any proposed transfer by the Sithe
Partners of all or a portion of their respective Interests to Exelon
Corporation, a Pennsylvania corporation, or any Affiliates of Exelon
Corporation.

     15.3 LIMITATIONS ON TRANSFER.

  Notwithstanding any provision of this Section 15 to the contrary, any
otherwise permitted transfer shall be deemed void ab initio and shall have no
force or effect, to the fullest extent permitted by law, if:

          (a) such transfer would, in the written opinion of a qualified tax
advisor or counsel to the Partnership, cause the Partnership to cease to be
classified as a partnership for federal or state income tax purposes;

          (b) such transfer would require the registration of such transferred
Interest pursuant to any applicable federal or state securities laws or would
subject the Partnership to regulation under the Investment Company Act of 1940
or the Employee Retirement Income Security Act of 1974, each as amended;

          (c) such transfer would result in a material adverse effect on the
Partnership with respect to any Applicable Law, or is proposed to be made to any
Person who lacks the legal right, power, or capacity to own such Interest;

          (d) in the case of a transfer by Oswego Cogen, such transfer is
proposed to be made to any Person who is, or whose Affiliate is, an "electric
utility company", "electric utility holding company", "public utility company"
or "public utility holding company" under PUHCA (other than any such Person that
is exempt pursuant to Sections 3(a)(3) or 3(a)(5) of PUHCA); PROVIDED, HOWEVER,
that the foregoing transfer limitation shall cease to apply if and to the extent
that the Project has ceased to qualify as a Qualifying Facility and the
Partnership is not pursuing actions reasonably intended to reestablish
Qualifying Facility status for the Project;

          (e) in the case of a transfer by one of the Sithe Partners, such
transfer is proposed to be made to any Person who is, or whose Affiliate is, an
"electric utility company", "electric utility holding company", "public utility
company" or "public utility holding company" under PUHCA (other than any such
Person that is exempt pursuant to Sections 3(a)(3) or 3(a)(5) of PUHCA), if,
taking into account the status of the existing Partners in the Partnership (and
their Affiliates) such transfer would result in a loss by the Project of its
status as a Qualifying Facility; PROVIDED, HOWEVER, that the foregoing transfer
limitation shall cease to apply if and to the extent that the Project has ceased
to qualify as a Qualifying Facility and the Partnership is not pursuing actions
reasonably intended to reestablish Qualifying Facility status for the Project;
or

          (f) such transfer would result in a breach of any material obligation
under any material contract or agreement to which the Partnership is a party.

     15.4 MANDATORY SALES OR RESTRUCTURING.

<Page>

          (a) In the event that the Commission determines, pursuant to an order
that has not been stayed, enjoined or set aside, that Enron Corp. is not an
exempt holding company under Section 3(a)(3) or Section 3(a)(5) of PUHCA, Oswego
Cogen shall take such actions as may be reasonably necessary to avoid the loss
by the Partnership of the Project's status as a Qualifying Facility, including,
if necessary, the sale or other restructuring of its Interest. Any such sale,
transfer or restructuring of the Interest of Oswego Cogen shall be subject to
all restrictions on the transfer of its Interest contained in Section 15.3. A
sale or transfer by Oswego Cogen of its Interest pursuant to this Section 15.4
shall not require the consent of any Partner unless its proposed transferee is
described in subclause (ii) of the last sentence of Section 15.1, in which case
prior consent of the other Partners shall be required. Notwithstanding the
foregoing, if the sale or transfer of the Interest by Oswego Cogen would result
in a termination of the Partnership for purposes of Code Section 708, Oswego
Cogen shall hold harmless and pay to each of the other Partners an amount equal
to (i) the net present value of any adverse net federal and state income tax
consequences it will suffer as a direct result of the termination of the
Partnership for tax purposes, including, without limitation, any readjustment to
the depreciation periods or methods applicable to the Partnership's depreciable
properties, plus (ii) an additional payment necessary to reimburse the Partners
for the net federal and state income taxes owed on any payment under the
foregoing subclause (i) and this subclause (ii) (such net federal and state
income taxes to be conclusively presumed to be imposed at a combined effective
tax rate of forty percent (40%) regardless of the actual effective tax rate or
tax situation of the Partners or of any Partner); PROVIDED, HOWEVER, that Oswego
Cogen shall not be required to pay any amount pursuant to the foregoing
subclause (ii) in the event that Oswego Cogen obtains an opinion from a
nationally recognized accounting or law firm, selected by Oswego Cogen and
consented to by the Partners holding a majority in interest of the Interests of
the Partnership (excluding the Interest held by Oswego Cogen), such consent not
to be unreasonably withheld, to the effect that the payment by Oswego Cogen of
amounts pursuant to subclause (i) should not be treated as taxable income to the
Partners. For purposes of this Section 15.4, any net present value calculation
shall be determined using a discount rate of ten percent (10%) and an assumed
effective combined income tax rate of forty percent (40%).

          (b) In the event that Oswego Cogen determines, in its reasonable
business judgment, that a sale or other restructuring of its Interest pursuant
to Section 15.4(a) would be reasonably likely to have a material adverse effect
on it, Oswego Cogen may provide written notice thereof to the General Partner,
and, if requested by Oswego Cogen, the General Partner shall consider in good
faith any reasonable proposals of Oswego Cogen that may eliminate the (i)
regulatory or contractual requirements for the Project to continue to qualify as
a Qualifying Facility and (ii) the requirement hereunder for Oswego Cogen to
sell or otherwise restructure its Interest; PROVIDED, HOWEVER, that the General
Partner shall not be required to take any action that would not be in compliance
with the Indenture; and PROVIDED, FURTHER, that if any such proposed action
would not be in compliance with the Indenture, the General Partner agrees, upon
the reasonable written request of Oswego Cogen, to cooperate in good faith with
Oswego Cogen in seeking on behalf of the Partnership and Sithe Funding a waiver
or modification to the Indenture if the General Partner reasonably determines
that such proposed action would not have an adverse effect on the business,
financial condition, properties or prospects of the Partnership. In making such

<Page>

determination, the General Partner shall consider, among other things, (x) any
financial support or contributions to be provided or made by Oswego Cogen to or
for the benefit of the Partnership and/or any of the other Partners in
connection with or resulting from any change in the status of the Project and
the Partnership proposed by Oswego Cogen pursuant to this Section 15.4(b) and
(y) letters from each of Standard & Poor's Ratings Corporation, a Division of
the McGraw-Hill Companies, Moody's Investors Service, Inc. and Fitch, Inc., or
the rating agencies then rating the Bonds, obtained by Oswego Cogen (or, if
reasonably requested by Oswego Cogen, by the Partnership or Sithe Funding, at
the expense of Oswego Cogen), stating that the rating of the Bonds (as defined
in the Indenture) will not be reduced as a result of any change in the status of
the Project and the Partnership proposed by Oswego Cogen pursuant to this
Section 15.4(b) (collectively, the "Ratings Confirmation Letters"). For the
avoidance of doubt, the General Partner shall have no obligation to consider any
proposed action of, or cooperate with, Oswego Cogen pursuant to this Section
15.4(b) in the event that Oswego Cogen fails to obtain, or cause to be obtained,
the Ratings Confirmation Letters and provide copies thereof to the General
Partner. The costs and expenses of seeking any waiver or modification to the
Indenture for the purposes of this Section 15.4(b) shall be borne solely by
Oswego Cogen, and Oswego Cogen hereby agrees to indemnify and hold harmless the
Partnership and each of the other Partners for any costs or expenses incurred by
the Partnership or such Partner, as the case may be, in furtherance of the
foregoing.

     15.5 CERTAIN SALES BY THE SITHE PARTNERS.

  In the event that a sale or transfer of a portion of any of the Interests held
by the Sithe Partners is necessary to avoid the loss by the Partnership of the
Project's status as a Qualifying Facility as a result of the exercise by Exelon,
or any successor or assignee thereof, of any right to acquire an additional
ownership interest in Sithe Energies, any such sale or transfer shall be subject
to all of the restrictions on the transfer of Interests contained in Section
15.3. A sale or transfer by any of the Sithe Partners pursuant to this Section
15.5 shall not require the consent of any Partner (but only to the extent of the
portion of such sale that is necessary to avoid the loss by the Partnership of
the Project's status as a Qualifying Facility), unless its proposed transferee
is described in subclause (ii) of the last sentence of Section 15.1, in which
case prior consent of the other Partners shall be required. Notwithstanding the
foregoing, if the sale or transfer of the Interest by the selling Sithe
Partner(s) would result in a termination of the Partnership for purposes of Code
Section 708, the selling Sithe Partner(s) shall hold harmless and pay to each of
the other Partners an amount equal to (i) the net present value of any adverse
net federal and state income tax consequences it will suffer as a direct result
of the termination of the Partnership for tax purposes, including, without
limitation, any readjustment to the depreciation periods or methods applicable
to the Partnership's depreciable properties, plus (ii) an additional payment
necessary to reimburse the Partners for the net federal and state income taxes
owed on any payment under the foregoing subclause (i) and this subclause (ii)
(such net federal and state income taxes to be conclusively presumed to be
imposed at a combined effective tax rate of forty percent (40%) regardless of
the actual effective tax rate or tax situation of the Partners or of any
Partner); PROVIDED, HOWEVER, that the selling Sithe Partner(s) shall not be
required to pay any amount pursuant to the foregoing subclause (ii) in the event
that such selling Sithe Partner(s) obtains an

<Page>

opinion from a nationally recognized accounting or law firm, selected by such
selling Sithe Partner(s) and consented to by Oswego Cogen, such consent not to
be unreasonably withheld, to the effect that the payment by such selling Sithe
Partner(s) of amounts pursuant to subclause (i) should not be treated as taxable
income to the Partners. For purposes of this Section 15.5, any net present value
calculation shall be determined using a discount rate of ten percent (10%) and
an assumed effective combined income tax rate of forty percent (40%).

     15.6 EXPENSES.

  No transfer described in Sections 15 shall be effective unless the transferor
or transferee pays to the Partnership all direct out-of-pocket costs reasonably
incurred by the Partnership as a result of such transfer and indemnifies the
Partnership (in a manner which is reasonably satisfactory to the General
Partner) for any such costs that may be reasonably incurred by the Partnership
thereafter as a result of such transfer.

     16. RESERVED.

     17. SUBSTITUTED LIMITED PARTNER.

     17.1 CONDITIONS.

  No assignee of the whole or any portion of the Interest of any Person who is
not a General Partner shall have the right to become a Substituted Limited
Partner in place of his assignor, unless all of the following conditions are
satisfied:

          (a) a written instrument of assignment, fully executed and
acknowledged by the assignor, has been filed with the Partnership setting forth
the intention of the assignor that the assignee become a Substituted Limited
Partner in its place;

          (b) the assignor and assignee have executed and acknowledged such
other instruments as the General Partner may deem necessary or desirable to
effect such admission, including the written acceptance and adoption by the
assignee of the provisions of this Agreement; and

          (c) the General Partner has consented in writing to the substitution,
which consent will not be unreasonably withheld.

     17.2 EFFECT OF ASSIGNMENT WITHOUT SUBSTITUTION.

  In the case of assignments where the assignee does not become a Substituted
Limited Partner, the Partnership shall recognize the assignment not later than
the last day of the calendar month following receipt of notice of assignment and
required documentation for the limited purposes of allocating Profits and Losses
and making distributions pursuant to the terms of this Agreement.

     17.3 DISCRETION OF GENERAL PARTNER.

<Page>

  The General Partner may elect to treat an assignee which has not become a
Substituted Limited Partner as a Substituted Limited Partner in the place of its
assignor should it deem, in its reasonable judgment, that such treatment is in
the best interest of the Partnership for any of its purposes or for any of the
purposes of this Agreement.

     17.4 CONSENT NOT REQUIRED.

  No consent of the Limited Partners is required to effect the substitution of a
Limited Partner, except that a Limited Partner assigning its Interest must
evidence its intention that its assignee be admitted as a Substituted Limited
Partner in its place and execute any instruments required in connection
therewith.

     17.5 AMENDMENT OF CERTIFICATE.

  The General Partner will amend the Certificate of Limited Partnership if, as
and when required to reflect the substitution of the Limited Partner.

     17.6 MISCELLANEOUS.

  Upon the bankruptcy or insolvency of a Limited Partner or upon the dissolution
or other cessation of a non-individual Limited Partner's existence as a legal
entity, the authorized representative of such entity shall have all the rights
of the Limited Partner for the purpose of effecting the orderly winding up and
dissolution of the business of such entity, and shall have such power as such
entity possessed to constitute a successor as an assignee of its Interest in the
Partnership and to join, if necessary, with such assignee in making application
to substitute such assignee as the Limited Partner.

     18. WITHDRAWAL.

     The General Partner shall not withdraw from the Partnership without the
express written consent of all of the Partners. The withdrawal of any Limited
Partner shall not cause a dissolution of the Partnership, and the Business shall
continue without interruption. In the event of the withdrawal, for any reason,
of the General Partner, the Partnership shall dissolve, unless the Business is
continued by any remaining General Partner. In the event of the withdrawal of
the last remaining General Partner, the Partnership shall dissolve, unless
within 90 days after the occurrence of such withdrawal, each of the Partners not
Affiliated with such General Partner agree in writing to continue the Business
of the Partnership and to the appointment, effective as of the date of
withdrawal of the last General Partner, of one or more additional General
Partners, who are hereby authorized to and shall continue the Business of the
Partnership.

     19. DISSOLUTION AND LIQUIDATION OF THE PARTNERSHIP.

     19.1 EVENTS CAUSING DISSOLUTION.

  The Partnership shall terminate upon the happening of any of the following
events:

<Page>

          (a) the removal or withdrawal of the General Partner, except as
provided in Sections 14 and 18 hereof;

          (b) the sale or other disposition of all or substantially all of the
assets of the Partnership;

          (c) the election by the General Partner and the approval of each of
the Limited Partners to dissolve the Partnership; or

          (d) the entry of a decree of judicial dissolution of the Partnership.

Dissolution of the Partnership shall be effective on the day on which the event
occurs giving rise to the dissolution, but the Partnership shall not terminate
until the Partnership's Certificate of Limited Partnership shall have been
cancelled, and the assets of the Partnership shall have been distributed as
provided in Section 19.2(d) hereof. Notwithstanding the dissolution of the
Partnership, prior to the termination of the Partnership, as aforesaid, the
Business of the Partnership shall continue to be governed by this Agreement.

     19.2 LIQUIDATION.

          (a) Upon dissolution of the Partnership, the General Partner, or, if
none, a Person approved in accordance with Applicable Laws by the Limited
Partners (a "Liquidating Trustee"), shall liquidate the assets of the
Partnership, apply and distribute the proceeds thereof as contemplated by this
Agreement and cause the cancellation of the Partnership's Certificate of Limited
Partnership.

          (b) Notwithstanding the foregoing, in the event that the General
Partner or the Liquidating Trustee, as the case may be, shall determine that an
immediate sale of part or all of the Partnership assets would cause undue loss
to the Partners, the General Partner or the Liquidating Trustee, as the case may
be, in order to avoid such loss, may, after having given notice to all the
Partners, to the extent not then prohibited by Applicable Laws, either defer
liquidation of and withhold from distribution for a reasonable time any assets
of the Partnership except those necessary to satisfy the Partnership's then
current debts and obligations, or distribute the assets in kind.

          (c) If any assets of the Partnership are to be distributed in kind,
such assets shall be distributed on the basis of the fair market value thereof,
and any Person entitled to any interest in such assets shall receive such
interest therein as a tenant-in-common with all other Persons so entitled. The
fair market value of such assets shall be determined by an independent appraiser
to be selected by the General Partner or the Liquidating Trustee, as the case
may be.

          (d) The proceeds from the liquidation of the assets of the Partnership
shall be distributed, after all allocations of Profit or Loss (and items of
income, gain, loss and deduction) have been made in accordance with Section 11
hereof, in the following order:

               (i) First, to pay the expenses of liquidation of, and the claims
     and obligations

<Page>

     of the Partnership, including any obligations under the Project Documents,
     other than the debts or obligations owing to the Partners whether matured
     or contingent, or to establish reasonable reserves therefor, all in
     accordance with Applicable Laws;

               (ii) Second, to such debts or obligations as are owing to the
     Partners;

               (iii) Third, to Oswego Cogen, in an amount equal to the lesser of
     (i) the balance of its Special Distributions Account and (ii) its positive
     Capital Account balance;

               (iv) Fourth, to any Partner having a positive balance in its TCC
     Distribution Account (or subaccount) an amount equal to the lesser of: (i)
     the balance of such Partner's TCC Distribution Account (or subaccount) and
     (ii) such Partner's positive Capital Account balance (determined, in the
     case of Oswego Cogen, after reducing such Capital Account balance to take
     into account any distributions made pursuant to the provisions of Section
     19.2(d)(iii) hereof);

               (v) Fifth, to the Partners in proportion to, and up to the
     amounts of, their respective positive Capital Account balances (determined
     after reducing the balance of the Capital Account of each Partner to take
     into account any distributions made to such Partner pursuant to the
     provisions of Sections 19.2(d)(iii) or (iv) hereof); and

               (vi) Sixth, to the Partners in proportion to their Percentage
     Interests.

          (e) In the event that any current or former General Partner's Capital
Account is negative upon liquidation of the Partnership (or of the General
Partner's interest in the Partnership), and after giving effect to all
contributions (including any amount considered contributed by such General
Partner to the Partnership under Section 1.704-1(b)(2)(iv)(c) of the
Regulations), distributions and allocations for all taxable years, including the
taxable year during which the final liquidating distribution occurs, such
General Partner shall contribute to the capital of the Partnership the amount
necessary to restore its Capital Account to zero (or, if applicable, the amount
determined pursuant to Section 14.2(c) hereof), and the amount so contributed
shall be treated as additional proceeds from the liquidation of the assets of
the Partnership and shall be distributed in accordance with and pursuant to
Section 19.2(d) hereof. The General Partner shall make such contribution by no
later than the end of the taxable year during which such liquidation occurs (or,
if later, within 90 days after the date of such liquidation). This Section
19.2(e) is intended to impose an unconditional obligation on the General Partner
to restore any deficit balance in its Capital Account in accordance with the
requirements of Section 1.704-1(b)(2)(ii)(b)(3) of the Regulations, and it shall
be interpreted and applied accordingly.

          (f) The General Partner may, upon the liquidation of the Partnership
or of the General Partner's Interest, expressly assume any liability of the
Partnership. Any such assumption of liability by the General Partner is intended
to be treated as an assumption of such liability for purposes of Section
1.704-1(b)(2)(iv)(c) of the Regulations, and this Section 19.2(f) shall be
interpreted and applied accordingly.

                             affecting Owner or the Project, the cost of which
                             would be an expense to Owner under any Project
                             Document, would affect the revenues of the Project,
                             would be covered by any Project insurance policy or

Restrictions on
Expenditures:                Operator shall be authorized to make such
                             expenditures and incur such expenses on behalf of
                             Owner as are approved by Owner in the annual Budget
                             for the Project. In addition, Operator may incur
                             expenses on behalf of Owner for purposes of
                             maintenance and repairs up to [$1,000,000] per

                             event of an imminent risk of personal injury,
                             significant property or environmental damage, or

                             (an "Emergency"), Operator is authorized to incur
                             any necessary costs and expenses without Owner's
                             prior approval in responding to or mitigating any
                             damage, loss or injury threatened by such

                             (to be included in the agreement). Operator shall
                             notify Owner as soon as practicable under the
                             circumstances of the occurrence of any Emergency
                             and any resulting costs and expenses incurred or
                             proposed to be incurred in connection with such
                             Emergency.

                             Agreement. Operator shall promptly notify Owner of
                             the need, if any, to make advances of the estimated

                             by the 20th day of each calendar month a statement
                             and reasonably detailed breakdown of actual costs
                             for the preceding month.

                             to Operator in such year; PROVIDED, HOWEVER, that
                             such limitations on liability shall not apply with
                             respect to any loss, damage or liability resulting
                             from or arising out of the fraud, gross negligence
