If, on the Scheduled Closing Date, the Owner Participant has made the Owner
Participant's Commitment available to the Owner Lessor in accordance with
Section 2.2(b), the Closing does not occur on such date and the Owner Lessor has
not returned such funds to the Owner Participant on or before 1:00 p.m., New
York City time, on such date, then Calpine shall reimburse the Owner Participant

including the day that such funds were made available to the Owner Lessor by the

resulting from such investments and, if such funds are made available to the
Owner Lessor and utilized to pay the Purchase Price or Transaction Costs on the
Closing Date, Calpine shall reimburse the Owner Lessor for any net loss realized
on the investment of such funds. If such funds are not so


                                       5
   13

utilized, Calpine shall, in addition to its obligation to reimburse the Owner
Participant for loss of use as provided above, reimburse the Owner Participant
on the date such funds are returned to the Owner Participant for any net loss
realized on the investment of such funds. In order to obtain funds for payment
of the Purchase Price or Transaction Costs or to return funds made available to
the Owner Lessor by the Owner Participant, the Owner Lessor is authorized to
sell any investments or obligations purchased as aforesaid.

        (e) Expiration of Commitments. The obligation of the Owner Participant
to make its Equity Investment shall expire at 11:59 p.m., New York City time, on
December 31, 2000. If the Closing Date has not occurred on or before December
31, 2000 the Transaction Parties shall have no obligation to consummate the
transactions contemplated under this Agreement and, except as provided in
Sections 2.3, 9.1 and 9.2, all obligations of the Transaction Parties shall

the Owner Lessor (with funds provided by the Owner Participant), assuming all
invoices have been approved by Calpine and received by the Owner Lessor by
December 26, 2000. All other Transaction Costs, fees, costs and expenses
incurred by the Facility Lessees, the Owner Lessor and the Owner Participant
shall be paid by Calpine. If the Overall Transaction is not consummated for any
reason (including as a result of the Facility Lessees' terminating this
Agreement pursuant to Section 12(a)), then Calpine shall bear all Transaction
Costs; provided, however, that Calpine shall not be obligated to pay Transaction
Costs incurred by the Owner Participant if the Overall Transaction is not
consummated on the basis of the provisions of this Agreement due to a failure of
the Owner Participant to satisfy any condition to the Closing required to be
satisfied by the Owner Participant.

for, and will pay as Supplemental Rent on an After-Tax Basis to the

the transactions contemplated hereby, including transfer of certain of its
assets and properties to the Owner Lessor, in good faith and without any intent
to defraud creditors of such Facility Lessee or subsequent purchasers. The
execution and delivery of the Operative Documents to which such Facility Lessee

whether or not such liabilities are required under GAAP to be shown on each
Facility Lessee's balance sheet. The execution and delivery of the Operative
Documents to which each Facility Lessee is a party will not leave it with
property remaining in its hands which would constitute unreasonably small assets
or capital, and each Facility Lessee has and, after giving effect to such
transactions will have, an adequate amount of assets and capital to engage in
its business now and in the future, based on the actual and anticipated needs
for capital of the businesses anticipated to be conducted by such Facility
Lessee, and based upon the other information described herein. After giving
effect to the transactions contemplated under the Operative Documents, each
Facility Lessee will be able to pay all of its debts and liabilities, including
unrecorded contingent liabilities, as they mature, each Facility Lessee will
have positive cash flow after paying all of its scheduled and anticipated debt

current assets in the ordinary and usual course of business to pay recurring
current debt, short-term debt and long-term debt as such debts mature.

         (ff) No Additional Fees. Except for the fees referred to in clause
(xviii) and (xix) of the definition of Transaction Costs, such Facility Lessee
has not paid or become obligated to pay any fee or commission to any broker,
finder or intermediary for or on account of arranging the financing of the
transactions contemplated by the Operative Documents.

Owner Participant, the Owner Lessor, the Indenture Trustee, the Pass Through
Trustee nor any Certificateholder solely as a result of execution, delivery and
performance of, and the consummation of the transactions contemplated by the
Operative Documents shall be or become (i) subject to regulation as a "public
utility company," "holding company," an "affiliate" of a "holding company" or a

electricity at market-based rates and with waivers of regulations customarily
granted to a public utility that sells wholesale power


                                       14

Participant, the Indenture Trustee and the Pass Through Trustee by or on behalf
of such Facility Lessee or any of its Affiliates in connection with the
transactions contemplated hereby contains any untrue statement of a material
fact or omit to state a material fact necessary in order to make the statements
contained therein, in light of the circumstances under which they were made, not
misleading; provided, that no representation or warranty is made with regard to
(i) any projections or other forward-looking statements provided by or on behalf
of the Facility Lessee, or (ii) the descriptions of the Operative Documents or
the tax consequences to beneficial owners of Certificates; provided, further,
each of the Transaction Parties acknowledge and agrees that (i) Calpine has
heretofore provided to the Appraiser, solely in order to assist the Appraiser in
connection with the preparation of the appraisal to be delivered by the
Appraiser to certain of the Transaction Parties at the Closing, certain (1)
general market information, (2) information about the Maine and Rhode Island
energy markets and (3) information passed along from other Persons and (ii) that
the Facility Lessee makes no representation or warranty whatsoever with respect
to the information described in clause (i) above except to the extent expressly
set forth in Section 4(b) of the Tax Indemnity Agreement.

access to transmission services and ancillary services sufficient to sell the
net generating capacity of such Facility at wholesale, and such Facility Lessee
has the authority to sell wholesale electric power from the net generating
capacity of such generating Facility at market-based rates.

default under any Operative Document.

Letter of Credit on or before a date that is not less than 45 days prior to the

         (f) As provided in the Qualifying Letter of Credit, in the event that
the Qualifying Letter of Credit is not replaced as provided in paragraphs (b),
(c) or (d) above, the Owner Participant shall be entitled to draw the full
amount thereof and cause the proceeds of such drawing to be deposited into the
Equity Collateral Account. Any such drawing or deposit shall not relieve the
Guarantor from its obligations under paragraphs (a), (b), (c) and (d) above to
maintain a Qualifying Letter of Credit, unless the Guarantor is unable to
discharge such obligations using its commercial efforts, but the failure to
maintain a Qualifying Letter of Credit shall not constitute, in whole or in
part, the basis of any Lease Default or Lease Event of Default under any
Operative Document. The Guarantor shall ensure at all times that the amounts on
deposit in the Equity Collateral Account from time to time are at least equal to
the applicable L/C Termination Values set forth in Exhibit L hereto for each
date set forth in such Exhibit L, as adjusted pursuant to Section 5.46(j) hereof
and subject to Section 5.46(k) hereof, provided that the failure to do so shall
not constitute, in whole or in part, the basis of any Lease Default or Lease
Event of Default under any Operative Document, and except to the extent
expressly provided in Section 16(e) of each Facility Lease. If the Guarantor,
subsequent to the Equity Collateral Account deposit described above (and prior
to application of such proceeds to the account of the Owner Participant as set
forth in paragraph (g) below) establishes a new Qualifying Letter of Credit and
is otherwise in compliance with its obligations under paragraphs (a), (b), (c)
and (d) above, the Owner Lessor shall forthwith return by wire transfer of
immediately available funds, the amounts held in the Equity Collateral Account
to the Guarantor.

         (g) The Equity Collateral Account shall be a segregated pledged
account, the documentation of which will be in form and substance satisfactory
to the Owner Participant, subject to a first priority security interest in favor
of the Owner Participant, and maintained by the Owner Participant to secure the
Guarantor's obligation under the Calpine Guaranties to pay the Equity Portion of
Termination Value as set forth in Section 2.1 of both such Calpine Guaranties.
The Owner Lessor shall be entitled (1) to retain control over the amounts on
deposit therein, and (2) to foreclose upon the funds therein upon the occurrence
and during the continuance of a Drawing Event. The Owner Participant shall
direct the Owner Lessor to, and the Owner Lessor shall, forthwith pay over, by
wire transfer of immediately available funds, to the Guarantor, any balance of
amounts remaining in the Equity Collateral Account after the Equity Portion of
Termination Value as specified in Section 2.1(b) of each Calpine Guaranty,
together with other amounts then due and payable to the Owner Participant and
Owner Lessor by the Facility Lessees or the Guarantor under the Operative
Documents, have been paid.

         (h) Costs and Expenses. The Guarantor shall pay the reasonable and
documented costs and expenses incurred by the Owner Participant in connection
with the actions referred to in this Section 5.46, except costs and expenses
attributable to a transfer by the Owner Participant of its rights in the Member
Interest pursuant to Section 7.1 of the Participation Agreement.

         (i) Gross Ups For Withholding Taxes. (i) If at any time the issuer of
any Qualifying Letter of Credit shall not be a United States person (within the
meaning of Section 7701 of the Code) and any deduction or withholding of tax is
required by Applicable Law (in effect at the time of issuance of the Qualifying
Letter of Credit) to be made in respect of any drawing or payment thereunder,
then Guarantor shall cause the Qualifying Letter of Credit to provide that the
amount to be paid thereunder shall be increased by the amount of such deduction
or


                                       38
   46

withholding such that the amount received by the Owner Participant is not less
than the amount it would have received in the absence of the application of any
such deduction or withholding.

                  (ii) In the event that there occurs a change in Applicable Law
    subsequent to the date any Qualifying Letter of Credit is issued such that
    deduction or withholding of tax is applicable to any payment under any such
    Qualifying Letter of Credit, the Guarantor shall (within 30 days after a
    Responsible Officer has Actual Knowledge of such change) furnish to the
    applicable Owner Participant an additional Qualifying Letter of Credit in an
    available amount equal in aggregate to the amount of withholding tax that
    would be required to be deducted or withheld on any given date in connection
    with a payment under the Qualifying Letter of Credit on such date.

         (j) Adjustment to L/C Termination Value. Any time an adjustment is made
to Termination Value pursuant to Section 3.4 of either of the Tiverton Facility
Lease or the Rumford Facility Lease, appropriate adjustments shall be made to
the L/C Termination Values set forth in such Facility Lease.

         (k) In the event of a failure by the Guarantor to comply with its
obligation under Sections 5.46(f) or (g) within 10 Business Days after receipt
of written notice of non-compliance from the Owner Participant, the Owner
Participant shall be entitled to deliver a notice of ECA Shortfall Event
referred to in Section 16(e) of each Facility Lease.


SECTION 6. COVENANTS OF THE OWNER LESSOR

         Section 6.1. Compliance with the LLC Agreement. The Owner Lessor hereby
covenants and agrees that it will:

         (a) comply with all of the terms of the LLC Agreement applicable to it;

Trust Indenture has not been terminated or discharged.

         Section 6.2. Owner Lessor's Liens. The Owner Lessor covenants that it
will not directly or indirectly create, incur, assume or suffer to exist any
Owner Lessor's Lien attributable to it and will promptly notify the applicable
Facility Lessee, the Owner Participant and the Indenture Trustee of the
imposition of any such Lien of which it has Actual Knowledge and shall promptly,
at its own expense, take such action as may be necessary to duly discharge such
Owner Lessor's Lien attributable to it.

         Section 6.3. Amendments to Operative Documents. The Owner Lessor
covenants that it will not unless such action is expressly permitted by the
Operative Documents (a) through its own action terminate any Operative Document

any such amendment, supplement, waiver or modification) such Operative Documents
in any manner or (c) except as provided in Section 11 hereof or Section


                                       39
   47

2.10 of the Collateral Trust Indenture, take any action to prepay or refund the
Lessor Notes or amend any of the payment terms of the Lessor Notes without, in
each case, the prior written consent of the applicable Facility Lessee so long
as no Significant Lease Default or Lease Event of Default shall have occurred
and be continuing and, in the case of clause (a) or (b), the Indenture Trustee
so long as the Lien of the Collateral Trust Indenture has not been terminated or
discharged.

         Section 6.4. Transfer of the Owner Lessor's Interest. Other than as
permitted by the Operative Documents, the Owner Lessor covenants that it will
not assign, pledge, sell, lease, convey or otherwise transfer any of its then
existing right, title or interest in and to the Owner Lessor's Interest, the
Lessor Estate or the other Operative Documents.

         Section 6.5. Owner Lessor; Lessor Estate. The Owner Lessor covenants
that it will not voluntarily take any action to subject the Owner Lessor or the
Lessor Estate to the provisions of any applicable bankruptcy, insolvency or
similar law (as now or hereafter in effect).

         Section 6.6. Limitation on Indebtedness and Actions. The Owner Lessor
covenants that it will not incur any indebtedness nor enter into any business or
activity except as required or expressly permitted by any Operative Document.

         Section 6.7. Change of Location. The Owner Lessor shall provide the
Owner Participant, the Indenture Trustee, the Certificateholders, the Pass
Through Trustee and the Facility Lessees 30 days' written notice of any
relocation of the Owner Lessor's chief executive office or the place where
documents and records relating to the Owner Lessor or the Lessor Estate are kept
from the location set forth in Section 3.2(g) and of any change in its name.


SECTION 7. COVENANTS OF THE OWNER PARTICIPANT

         Section 7.1. Restrictions on Transfer of Member Interest.

         (a) The Owner Participant covenants and agrees that it shall not during
the Facility Lease Term assign, convey or transfer any of its right, title or
interest in the Member Interest without the prior written consent of the
Facility Lessees and, so long as the Lien of the Collateral Trust Indenture has
not been terminated or discharged, without the prior written consent of the
Indenture Trustee; provided, however, that the Owner Participant may, without
such consent, assign to CSFB, on a contingent basis, the rights of the Owner
Participant to receive certain revenues and assets deriving from or attributable
to the Owner Participant's ownership of the Member Interest, pursuant to the
CSFB-OP Letter Agreement as in effect on the Closing Date, a copy of which has
been delivered to the Facility Lessees and the Indenture Trustee, and provided,
further, that the Owner Participant may, subject to Section 7.8, assign, convey
or transfer all or any part of its interest in the Member Interest without such
consent to a Person (the "Transferee") which shall assume the duties and
obligations of the Owner Participant under the Operative Documents with respect
to the interest being transferred pursuant to an OP Assignment and Assumption
Agreement substantially in the form of Exhibit J hereto, if each of the
following conditions shall have been satisfied on or prior to such transfer:


                                       40
   48

               (i) The Facility Lessees, the Indenture Trustee and the Pass
Through Trustee shall have received an opinion(s) of counsel (including an
opinion with respect to a guaranty pursuant to clause (iii) of this Section 7.1,
if applicable), which opinion(s) and counsel are reasonably satisfactory to the
Facility Lessees and consistent in scope to the opinions delivered on behalf of
the Owner Participant at the Closing, including that all regulatory approvals
required in connection with such transfer or necessary to assume the Owner
Participant's obligations under the Operative Documents shall have been
obtained;;

               (ii) the Transferee shall be a "United States person" within the
meaning of Section 7701(a)(30) of the Code;

               (iii) the Transferee shall be either (A) an Affiliate of the
transferor Owner Participant which does not otherwise qualify under clause (B)
below (but in any event, such Affiliate shall not be a Competitor of Calpine);
provided that all of the payment and performance obligations of the Transferee
with respect to the interest being transferred under the Operative Documents
shall be guaranteed by the transferor Owner Participant, or a Person then
providing a guaranty of the transferor Owner Participant's obligations
hereunder, pursuant to an OP Parent Guaranty or (B) a Person which meets, or the
payment and performance obligations of which with respect to the interest being
transferred under the Operative Documents are guaranteed (pursuant to a OP
Parent Guaranty) by a Person (the transferor Owner Participant or such other
guarantor, the "Transferee Guarantor") which meets, the following criteria: (1)
the tangible net worth of the Transferee or Transferee Guarantor, is at least
equal to $75 million calculated in accordance with GAAP; and (2) unless waived
in writing by the Facility Lessees prior to such transfer, such Transferee is
not a Competitor of Calpine; and

               (iv) upon consummation of such transfer, there shall not be more
than four (4) Owner Participants for the Overall Transaction; provided that any
related Owner Participants that shall have the same decision maker and vote
their interest together as a single vote shall count as one for purposes of this
clause (iv).

         Notwithstanding the foregoing, the restrictions set forth in Section
7.1 shall not inure to the benefit of the Facility Lessee if such transfer
occurs during the continuance of a Significant Lease Default or Lease Event of
Default.

         (b) For purposes of determining whether a Transferee is a "Competitor"
of Calpine, Calpine shall provide to the transferor Owner Participant on or
prior to the Closing Date a list of entities which Calpine reasonably believes
in its good faith judgment are competitors of Calpine or any of its Affiliates,
in the business in which Calpine or any of its Affiliates is engaged as of the
Closing Date, which list shall be attached to the Participation Agreement as
Exhibit K. Any such Person on such list shall be deemed to be a "Competitor" for
purposes of Section 7.1(a). The initial list of Competitors may be modified or
supplemented (in a manner consistent with the first sentence of this clause
(b)), from time to time, but no later than five Business Days after the Facility
Lessees receives each notice from the Owner Participant of its intent to
transfer its interest and, in addition, no more than once in any calendar year
plus each time the Facility Lessees receives such notice of transfer from the
Owner Participant, and such list as modified shall govern for the purposes of
this Section 7.1(b).


                                       41
   49

         (c) No Facility Lessee shall be responsible for any adverse tax
consequence to the Owner Lessor or the Owner Participant resulting from any
transfer pursuant to this Section 7.1 and the Pricing Assumptions shall not be
changed as a result of any such transfer.

         (d) The Owner Participant shall give the Owner Lessor, the Indenture
Trustee and the Facility Lessees 10 Business Days' prior written notice of such
transfer, specifying the name and address of any proposed Transferee and such
additional information as shall be necessary to determine whether the proposed
transfer satisfies the requirements of this Section 7.1. If requested by the
Owner Participant or the Indenture Trustee, the Facility Lessees will
acknowledge qualifying transfers. All reasonable fees, expenses and charges of
the Indenture Trustee, the Pass Through Trustee, any Qualifying Letter of Credit
Bank (if it should impose fees, expenses and charges), and the Facility Lessees
(including reasonable attorneys' fees and expenses in connection with any such
transfer or proposed transfer), including any of the foregoing relating to any
amendments to the Operative Documents required in connection therewith, shall be
paid by the Owner Lessor, without any right of indemnification from the Facility
Lessees or any other Person; provided, however, that the Owner Participant shall
have no obligation to pay fees, expenses or charges of the Facility Lessees as a
result of any transfer while a Significant Lease Default or a Lease Event of
Default is continuing, in which case the Facility Lessees shall be obligated to
pay such costs.

         (e) Upon any such transfer in compliance with this Section 7.1, (i)
such Transferee shall (x) be deemed the "Owner Participant" for all purposes,
and (y) enjoy the rights and privileges and perform the obligations of the Owner
Participant hereunder and under each of the OP Assignment and Assumption
Agreement, the Calpine Guaranties and each other Operative Document to which
such Owner Participant is a party, and each reference in this Agreement, the
Calpine Guaranties and each other Operative Document to the "Owner Participant"
shall thereafter be deemed to include such Transferee for all purposes and (ii)
the transferor Owner Participant and the OP Guarantor, if any, of such
transferor Owner Participant's obligations shall be released from all
obligations hereunder and under each other Operative Document to which such
transferor or OP Guarantor is a party or by which such transferor Owner
Participant or OP Guarantor is bound to the extent such obligations are
expressly assumed by a Transferee meeting the requirements of this Section 7.1;
provided, however, that in no event shall any such transfer waive or release the
transferor or its OP Guarantor from any liability accruing or existing in
respect of any period occurring on or prior to or occurring simultaneously with
such transfer.

         (f) The transfer restrictions set forth in Section 7.1 (other than the
requirement that the Owner Participant and the Transferee enter into an OP
Assignment and Assumption Agreement) shall also apply to any transfer of the
equity ownership interests of an Owner Participant which has as its sole (or
substantially equivalent to sole) business activity its participation in the
transactions contemplated by the Operative Documents. In the case of such a
transfer of equity ownership interests which satisfies such restrictions of this
Section 7.1, the Owner Participant's obligations under the Operative Documents
shall continue, but the Owner Participant shall, except in the case of a
transfer to a transferee described in clause (a)(iii)(A) above, procure a new OP
Parent Guaranty from a guarantor meeting the requirements of clause (a)(iii)(B)
above.


                                       42
   50

         Section 7.2. Owner Participant's Liens. The Owner Participant covenants
that it will not directly or indirectly create, incur, assume or suffer to exist
any Owner Participant's Lien and the Owner Participant shall promptly notify the
Facility Lessees and the Indenture Trustee of the imposition or existence of any
such Lien of which the Owner Participant has Actual Knowledge and shall
promptly, at its own expense, take such action as may be necessary to duly
discharge such Owner Participant's Lien.

         Section 7.3. Amendments or Revocation of LLC Agreement. Notwithstanding
anything to the contrary contained in the LLC Agreement, the Owner Participant
covenants that it will not (a) amend, supplement, or otherwise modify Section 10
of the LLC Agreement without the prior written consent of the Facility Lessees
so long as no Significant Lease Default or Lease Event of Default has occurred
and is continuing, and without the prior written consent of the Indenture
Trustee so long as the Lien of the Collateral Trust Indenture has not been
terminated or discharged, or (b) revoke, or otherwise waive compliance with or
terminate the LLC Agreement without the prior written consent of the Facility
Lessees so long as no Significant Lease Default or Lease Event of Default has
occurred and is continuing, and the Indenture Trustee so long as the Lien of the
Collateral Trust Indenture has not been terminated or discharged.

         Section 7.4. Bankruptcy Filings. The Owner Participant agrees that it
will not file a petition, or join in the filing of a petition, seeking
reorganization, arrangement, adjustment or composition of, or in respect of, the
Owner Lessor under the Bankruptcy Code, or any other applicable federal or state
law or the law of the District of Columbia.

         Section 7.5. Instructions. The Owner Participant agrees that it will
not instruct the Owner Lessor to take any action prohibited by this Agreement or
any other Operative Document.

         Section 7.6. Intentionally Omitted.

         Section 7.7. Intentionally Omitted.

         Section 7.8. Right of First Refusal. In the event the Owner Participant
desires to sell, lease, convey or otherwise transfer its Member Interest or
cause the Owner Lessor to sell all or substantially all of the Owner Lessor's
Interest at any time during the three (3) year period commencing on the
termination or expiration of the Facility Lease (except in the event that a
Lease Event of Default shall have existed at such time of termination or
expiration), any such sale or other transfer shall be subject to each Facility
Lessee's right of first refusal on the terms and conditions set forth in this
Section 7.8. The Owner Participant shall give the Facility Lessees prompt
written notice of all bona fide offers that have been received from any other
Person to purchase or acquire its interest of the Owner Lessor's Interest or the
Member Interest of the Owner Participant, and which offers it wishes to accept,
together with a full and complete statement of the price and all of the terms,
conditions and provisions contained in such offers. The Facility Lessees shall
thereafter have the right within a period of 45 days from and after the receipt
by them of such notice (the "Notice Period") to notify the Owner Participant of
its intent to exercise its right of first refusal; provided however, if both
Facility Lessees exercise their right of first refusal hereunder, then the
Facility Lessees shall collectively purchase or acquire 100% of the interest to
be conveyed in the Owner Lessor's Interest or the Member Interest of the Owner
Participant, as the case may be. If a Facility Lessee elects to exercise the
right provided in the


                                       43
   51

preceding sentence, it will within 60 days of such notice (the "Agreement
Period") execute a contract on the same terms and conditions as the offer giving
rise to such right. If neither of the Facility Lessees give such notice to the
Owner Participant within the 45 day period or execute such a contract within 60
days of such notice, the Owner Participant will be free to proceed under the
terms and conditions set forth in its notice to the Facility Lessees, unless the
failure to execute the contract within 60 days is attributable to acts or
omissions of the Owner Participant. In the event that such terms are revised in
any way that changes the agreement for sale, lease, conveyance or transfer such
that the terms of the sale are less favorable to the Owner Participant (it being
understood and agreed that any reduction in the price or a change in the terms
of payment thereof in a manner beneficial to the potential purchaser shall be
deemed to be less favorable to the Owner Participant), the Owner Participant
shall again comply with the notice and right of first refusal provisions of this
Section prior to entering into such revised agreement; provided that, for such
revised offer, the Notice Period shall be 10 Business Days from the date of such
new notice, and the Agreement Period shall not exceed 45 days from the date of
the Facility Lessees' notice accepting such new terms.


SECTION 8. COVENANTS OF THE INDENTURE TRUSTEE AND THE PASS THROUGH TRUSTEE

         Section 8.1. Indenture Trustee's Liens. Neither the Lease Indenture
Company, nor the Indenture Trustee will directly or indirectly create, incur,
assume or suffer to exist any Indenture Trustee's Lien attributable to it and
arising out of events or conditions not related to its rights in the Indenture
Estate or the administration thereof, and will promptly notify the Owner
Participant, the Owner Lessor and the Facility Lessees of the imposition of any
such Lien of which it has Actual Knowledge and shall promptly (and in any event
within 30 days of obtaining Actual Knowledge of such Lien), at its own expense,
take such action as may be necessary to duly discharge such Indenture Trustee's
Lien.

         Section 8.2. Pass Through Trustee's Covenant Not to Transfer Lessor
Notes.

         Section 8.2. The Pass Through Trustee agrees that it will not transfer
any Lessor Note (or any part thereof) to any entity (except to a successor Pass
Through Trustee appointed pursuant to the terms of the Pass through Trust
Agreement) until it receives from such entity a certification which makes a
representation and warranty as of the date of such transfer that no part of the
funds to be used by it for the purchase and holding of such Lessor Note (or any
part thereof) constitutes assets of any Plan or that such purchase and holding
will be covered by a prohibited transaction class exemption issued by the U.S.
Department of Labor.

             (xi) the continuing fees (if any) and expenses of the Owner Lessor

the Operative Documents (other than the Facility Leases and the Facility Site

this paragraph (ii), such transfer is required by the terms of the Operative

   54

Documents or occurs during the continuance of a Lease Event of Default;
(provided that this paragraph (ii) shall not serve to cap the indemnity to be
received by a transferee Indemnitee for a Claim (other than a Claim relating
solely to or arising solely out of any offer, transfer, sale, assignment or
other disposition of any such rights or interests) based on what the relevant
transferor Indemnitee would have received had no such transfer occurred);

             (iii) with respect to any Indemnitee, any Claim attributable to (i)
the gross negligence or willful misconduct of such Indemnitee or a Related Party
except to the extent such gross negligence or willful misconduct is attributable
to any breach by the Facility Lessees (or any of them) or any other Calpine
Party of any covenant, representation or warranty contained in any Operative
Document or (ii) any violation of Applicable Law by any such Person except to
the extent attributable to a violation of Applicable Law by the Facility Lessees
(or either of them) or any other Calpine Party or to any breach by the Facility
Lessees (or any of them) or such other Calpine Party of any covenant,
representation or warranty contained in any Operative Document;

             (iv) as to any Indemnitee, any Claim to the extent attributable to
the noncompliance of such Indemnitee or a Related Party, with any of the terms
of, or any misrepresentation or breach of warranty by such Indemnitee or Related
Party contained in any Operative Document made by such Indemnitee or Related
Party or any breach by such Indemnitee or a Related Party of any covenant
contained in any Operative Document or any breach by such Indemnitee or a
Related Party of any covenant contained in any Operative Document made by such
Indemnitee or Related Party except to the extent attributable to any breach by a
Facility Lessee or any other Calpine Party of any covenant, representation or
warranty contained in any Operative Document;

             (v) any Claim constituting or arising from an Owner Lessor's Lien;

             (vi) with respect to the Indenture Trustee and the Lease Indenture
Company, any Claim constituting or arising from a Indenture Trustee's Lien;

             (vii) with respect to the Owner Participant, any claim constituting
or arising from an Owner Participant's Lien;

             (viii) any Claim that is a Tax, or is a cost of contesting a Tax
whether or not the relevant Facility Lessee is required to indemnify therefor
pursuant to Section 9.2 hereof or under the Tax Indemnity Agreement;

             (ix) any failure on the part of the Administrator to distribute in
accordance with the LLC Agreement or the LLC Administration Agreements any
amounts received by it under the Operative Documents and distributable by it
thereunder;

             (x) a Claim arising out of a Indenture Default or Lease Indenture
Event of Default that is not also (or attributable to) a Lease Default or Lease
Event of Default;

             (xi) with respect to a particular Indemnitee and Related Party, any
obligation or liability expressly assumed in any Operative Document by the
Indemnitee seeking indemnification;


                                       47
   55

             (xii) any Claim that constitutes scheduled principal and/or
interest on the Lessor Notes, Additional Lessor Notes, or the corresponding
payments under the Certificates or any Additional Certificates; and

             (xiii) any Claim relating to the payment of any amount which
constitutes Transaction Costs which the Owner Participant is obligated to pay
pursuant to Section 2.3(a) hereof or any other amount to the extent such
Indemnitee or a Related Party has expressly agreed in any Operative Document to
pay such amount without express right of reimbursement;

provided that the terms "omission," "gross negligence" and "willful misconduct,"
when applied with respect to the Owner Lessor, the Owner Participant, the
Indenture Trustee, the Pass Through Trustee or any Affiliate of any thereof,
shall not include any liability imputed as a matter of law to such Indemnitee
solely by reason of any such entity's interest in the Facilities or the Facility
Sites or such Indemnitee's failure to act in respect of matters which are or
were the obligation of the Facility Lessees under this Agreement or any other
Operative Document. Nothing herein shall be deemed to constitute a guaranty of
any useful life or any present or future residual value of the Facilities or a
guaranty that any amount of any Secured Indebtedness will be paid.

         (c) Insured Claims. Subject to the provisions of paragraph (e) of this
Section 9.1, in the case of any Claim indemnified by the Facility Lessees
hereunder which is covered by a policy of insurance maintained by the Facility
Lessees, each Indemnitee agrees, unless it and each other Indemnitee shall waive
its rights to indemnification (for itself and each Related Party thereto) in a
manner reasonably acceptable to the Facility Lessees, to cooperate, at the sole
cost and expense of the Facility Lessees, with insurers in exercise of their
rights to investigate, defend or compromise such Claim.

         (d) After-Tax Basis. The Facility Lessees agree that any payment or
indemnity pursuant to this Section 9.1 in respect of any Claim shall be made on
an After-Tax Basis to the Indemnitees.

         (e) Claims Procedure. Each Indemnitee shall promptly after such
Indemnitee shall have Actual Knowledge thereof notify the Facility Lessees of
any Claim as to which indemnification is sought; provided, that the failure so
to notify the Facility Lessees shall not reduce or affect the Facility Lessees'
liability which it may have to such Indemnitee under this Section 9.1, and no
payment hereunder by the Facility Lessees to an Indemnitee shall be deemed to
constitute a waiver or release of any right or remedy that the Facility Lessee
may have against any such Indemnitee for actual damages resulting directly from
the failure or delay of such Indemnitee to give the Facility Lessees such
notice. Subject to the foregoing, any amount payable to any Indemnitee pursuant
to this Section 9.1 shall be paid within thirty (30) days after receipt of such
written demand therefor from such Indemnitee, accompanied by a certificate of
such Indemnitee stating in reasonable detail the basis for the indemnification
thereby sought and (if such Indemnitee is not a party hereto) an agreement to be
bound by the terms hereof as if such Indemnitee were such a party. The foregoing
shall not, however, constitute an obligation to disclose confidential
information of any kind without the execution of an appropriate confidentiality
agreement. Promptly after the Facility Lessees receive notification of such
Claim accompanied by a written statement describing in reasonable detail the
Claims which are the


                                       48
   56

subject of and basis for such indemnity and the computation of the amount so
payable, the Facility Lessees shall, without affecting its obligations
hereunder, notify such Indemnitee whether it intends to pay, object to,
compromise or defend any matter involving the asserted liability of such
Indemnitee. The Facility Lessees shall have the right to investigate and so long
as no Significant Lease Default or Lease Event of Default shall have occurred
and be continuing, the Facility Lessees shall have the right in its sole
discretion, to defend or compromise any Claim for which indemnification is
sought under this Section 9.1 which the Facility Lessees acknowledge is subject
to indemnification hereunder; provided that no such defense or compromise shall
involve any danger of (i) foreclosure, sale, forfeiture or loss of, or
imposition of a Lien on any part of the Facilities, the Facility Sites, the
Lessor Estate or the Indenture Estate or the impairment of the Facilities in any
material respect or (ii) any criminal liability being incurred or any material
adverse effect on such Indemnitee; provided, further, that no Claim shall be
compromised by the Facility Lessees on a basis that admits any criminal
violation or gross negligence or willful misconduct on the part of such
Indemnitee without the express written consent of such Indemnitee; and provided,
further, that to the extent that other Claims unrelated to the transactions
contemplated by the Operative Documents are part of the same proceeding
involving such Claim, the Facility Lessees may assume responsibility for the
contest or compromise of such Claim only if the same may be and is severed from
such other Claims (and each Indemnitee agrees to use reasonable efforts to
obtain such a severance). In the event that in the course of the investigation
or defense of a claim, the Facility Lessees shall in good faith reasonably
determine that it is not liable for indemnification with respect thereto under
this Section 9.1, it may give notice to the applicable Indemnitee of such fact;
and, in such case, any acknowledgment, theretofore made by the Facility Lessees
of liability with respect to such claim under this Section 9.1 shall be deemed
revoked, and the Facility Lessees may thereupon cease to defend such claim;
provided that (i) the Facility Lessees shall have given the Indemnitee
reasonable prior notice of its intention to renounce such acknowledgment, (ii)
the Facility Lessees' conduct regarding the defense of such claim or any
decision to withdraw from such defense shall not prejudice or have prejudiced
the Indemnitee's ability to contest such claim (taking into account, among other
things, the timing of the Facility Lessees' withdrawal and the theory or
theories upon which the Facility Lessees shall have based its defense), and
(iii) the Facility Lessees shall have given such Indemnitee all materials,
documents and records relating to its defense of such claim as such Indemnitee
shall have reasonably requested in connection with the assumption by such
Indemnitee of the defense of such claim at the cost and expense of such Facility
Lessee. In the event that the Facility Lessees shall cease to defend any claim
pursuant to the preceding sentence, the Facility Lessees shall indemnify each
Indemnitee, without regard to any exclusion that might otherwise apply
hereunder, to the extent that the actions of the Facility Lessees in defending
such claim or the manner or time of the Facility Lessees' election to withdraw
from the defense of such claim shall have caused such Indemnitee to incur any
loss, cost, liability or expense which such Indemnitee would not have incurred
had the Facility Lessees not ceased to defend such claim in such manner or such
time. If the Facility Lessees elect, subject to the foregoing, to compromise or
defend any such asserted liability, it may do so at its own expense and by
counsel selected by it. Upon the Facility Lessees' election to compromise or
defend such asserted liability and prompt notification to such Indemnitee of its
intent to do so, such Indemnitee shall cooperate at the Facility Lessees'
expense with all reasonable requests of the Facility Lessees in connection
therewith and will provide the Facility Lessee with all information not within
the control of the Facility Lessees as is reasonably


                                       49
   57

available to such Indemnitee which the Facility Lessees may reasonably request;
provided, however, that such Indemnitee shall not, unless otherwise required by
Applicable Law, be obligated to disclose to the Facility Lessees or any other
Person, or permit the Facility Lessees or any other Person to examine (i) any
income tax returns of the Owner Participant or (ii) any confidential information
or pricing information not generally accessible by the public possessed by the
Owner Participant (and, in the event that any such information is made
available, the Facility Lessees shall treat such information as confidential and
shall take all actions reasonably requested by such Indemnitee for purposes of
obtaining a stipulation from all parties to the related proceeding providing for
the confidential treatment of such information from all such parties). Where the
Facility Lessees, or the insurers under a policy of insurance maintained by the
Facility Lessees, undertake the defense of such Indemnitee with respect to a
Claim (with counsel reasonably satisfactory to such Indemnitee and without
reservation of rights against such Indemnitee), no additional legal fees or
expenses of such Indemnitee in connection with the defense of such Claim shall
be indemnified hereunder unless such fees or expenses were incurred at the
request of the Facility Lessees or such insurers. Notwithstanding the foregoing,
an Indemnitee may participate at its own expense in any judicial proceeding
controlled by the Facility Lessees pursuant to the preceding provisions, but
only to the extent that such party's participation does not in the reasonable
opinion of counsel to the Facility Lessees interfere with such control or
defense of such claim; provided, however, that such party's participation does
not constitute a waiver of the indemnification provided in this Section 9.1;
provided, further, that if and to the extent that (i) such Indemnitee is advised
by counsel that an actual or potential conflict of interest exists where it is
advisable for such Indemnitee to be represented by separate counsel or (ii)
there is a risk that such Indemnitee may be subject to criminal liability and
such Indemnitee informs the Facility Lessees that such Indemnitee desires to be
represented by separate counsel, such Indemnitee shall have the right to control
its own defense of such Claim and the reasonable fees and expenses of such
defense (including, without limitation, the reasonable fees and expenses of such
separate counsel) shall be borne by the Facility Lessees. So long as no Lease
Event of Default described in clause (a), (b), (g) or (h) of Section 16 of a
Facility Lease shall have occurred and be continuing, no Indemnitee shall enter
into any settlement or other compromise with respect to any Claim without the
prior written consent of the Facility Lessees unless (i) the Indemnitee waives
its rights to indemnification hereunder or (ii) the Facility Lessees have not
acknowledged their indemnity obligation with respect thereto and there is a
significant risk that a default judgment will be entered against such
Indemnitee. Nothing contained in this Section 9.1(e) shall be deemed to require
an Indemnitee to contest any Claim or to assume responsibility for or control of
any judicial proceeding with respect thereto.

        (f) Subrogation. To the extent that a Claim indemnified by the Facility
Lessees under this Section 9.1 is in fact paid in full by the Facility Lessees
or an insurer under an insurance policy maintained by the Facility Lessees, the
Facility Lessees (so long as no Lease Event of Default shall have occurred and
be continuing) or such insurer shall be subrogated to the rights and remedies of
the Indemnitee on whose behalf such Claim was paid to the extent of such payment
(other than rights of such Indemnitee under insurance policies maintained at its
own expense) with respect to the transaction or event giving rise to such Claim.
Should an Indemnitee receive any refund, in whole or in part, with respect to
any Claim paid by the Facility Lessees hereunder, it shall promptly pay over to
the Facility Lessees the lesser of (i) the amount refunded reduced by the amount
of any Tax incurred by reason of the receipt or accrual of such refund and
increased by the amount of any Tax (but not in excess of the amount of such


                                       50
   58

reduction) saved as a result of such payment or (ii) the amount the Facility
Lessees or any of their insurers has paid in respect of such Claim; provided
that, so long as a Significant Lease Default or Lease Event of Default shall
have occurred and is continuing such amount may be held by the Owner Lessor as
security for the Facility Lessees' obligations under the Facility Leases and the
other Operative Documents.

        (g) Minimize Claims. The Owner Participant, the Owner Lessor, and each
of the other Transaction Parties will use their respective reasonable and
diligent efforts to minimize Claims indemnifiable by the Facility Lessees under
this Section 9.1, including by complying with reasonable requests by the
Facility Lessees to do or to refrain from doing any act if such compliance is,
in the good faith opinion of the Owner Participant, the Owner Lessor, or such
other Transaction Party, as the case may be, of a purely ministerial nature or
otherwise has no unindemnified adverse impact on the Owner Participant, the
Owner Lessor, or such Transaction Party, as the case may be, or any Affiliate of
any thereof or on the business or operations of any of the foregoing.

        Section 9.2. General Tax Indemnity.

        (a) Indemnity. Except as provided in paragraph (b), the Facility Lessees
jointly and severally agree to indemnify each of the Owner Participant, the
Owner Lessor, the Lease Indenture Company in its individual capacity, the
Indenture Trustee, the Pass Through Company in its individual capacity, the Pass
Through Trustee, each Certificateholder and their respective successors and
assigns, the past and present partners or members of or holders of the ownership
interests in, as the case may be, the Owner Participant (each of the foregoing,
together with any Affiliate thereof, a "Tax Indemnitee") for, to hold each Tax
Indemnitee harmless from and to defend each Tax Indemnitee against all Taxes
that are imposed upon or with respect to or borne by or asserted against any Tax
Indemnitee, the Facilities, the Easements, the Facility Sites, or any portion or
Component thereof or any interest therein, or upon any Operative Document or
interest therein, or in any way arising out of, in connection with or relating
to, any of the following:

            (i) the construction, financing, refinancing, acquisition,
operation, warranty, ownership, possession, maintenance, repair, lease,
condition, alteration, modification, restoration, refurbishing, rebuilding,
return, transport, assembly, repossession, servicing, dismantling, abandonment,
retirement, decommissioning, preparation, installation, storage, replacement,
purchase, sale or other disposition, insuring, sublease, or other use or non-use
of, the imposition of any lien (or incurrence of any liability to refund or pay
over any amount as a result of any lien) on, the Facilities, the Facility Sites,
the Easements or any portion or Component thereof or any interest therein;

            (ii) the Facilities, the Facility Sites, the Easements, any portion
thereof or Component or interest therein, the applicability of the Facility
Leases to the Facilities, or the conduct of the business or affairs of the
Facility Lessees or Calpine, the Facilities or the Facility Sites;


                                       51
   59

            (iii) the manufacture, design, purchase, acceptance, rejection,
delivery, non-delivery, redelivery or condition of, or improvement to, the
Facilities, the Easements, the Facility Sites or any portion or Component
thereof, or any interest therein;

            (iv) the Facility Leases, or any other Operative Document, the
execution or delivery thereof, any other documents contemplated thereby or the
performance, enforcement or amendment of any terms thereof;

            (v) the payment or receipt of Periodic Rent, Basic Rent and
Supplemental Rent or any other payment, receipt or earning under the Facility
Leases or the Facility Site Subleases or arising from the Facilities, the
Facility Sites, the Easements, or any portion or Component thereof or any
interest therein;

            (vi) any other amount paid or payable pursuant to the Operative
Documents;

            (vii) the conveyance of title to the Facilities; or

            (viii) otherwise relating to the transactions contemplated by the
Operative Documents.

        Notwithstanding anything herein to the contrary and without regard to
paragraph (b) hereof, the Facility Lessees will indemnify the Owner Participant
and the Owner Lessor on an After-Tax Basis for any Taxes collected by way of
withholding (and any interest, penalties or additions to tax associated
therewith) (or for the failure to withhold taxes) imposed on the Lessor Notes or
the Additional Lessor Notes or any other payments to each Certificateholder or
the Indenture Trustee (each a "Certificateholder Indemnitee"), including any
penalties, interest, or additions to tax applicable in connection therewith;
provided, however, that if the Facility Lessees are required, for any reason, to
indemnify the Owner Participant or the Owner Lessor with respect to any failure
to withhold such tax, and the withholding tax would otherwise be an Excluded Tax
under Section 9.2(b) without regard to the first sentence of this paragraph,
then the Certificateholder Indemnitee with respect to which such withholding was
not made will pay the amount of tax not withheld to the relevant taxing
authority if such taxes remain unpaid or will reimburse the Facility Lessees for
the amount of tax not withheld, but paid to such taxing authority, on demand,
plus interest at (a) the Lease Debt Rate during the period commencing on the
date the Facility Lessees shall have made the indemnity payment to such taxing
authority and ending the earlier of the date of repayment by such Tax Indemnitee
and five Business Days after the date the Facility Lessees demand reimbursement
thereof pursuant to this sentence, and (b) the Overdue Rate for the period
thereafter to the date the Facility Lessees actually receive such payment.

        (b) Excluded Taxes. The indemnity provided for in paragraph (a) above
shall not extend to any of the following Taxes (the "Excluded Taxes"):

            (i) Taxes imposed by the United States federal government or any
state or local government, any political subdivision of any of the foregoing,
imposed on, based on or measured by gross or net income, receipts, capital gain,
capital or net worth, or conduct of business (other than, in each case, Taxes
that are in the nature of sales, use, rental, license, value added (to the
extent value added taxes are not imposed in clear and direct substitution for
income


                                       52
   60

taxes), property or similar taxes ("Income Taxes")), including any such Taxes
collected by way of withholding, minimum or alternative minimum taxes, and
franchise taxes; provided that this exclusion (i) shall not affect any express
requirement that payments be made on an "after-tax" basis nor shall it apply to
Taxes that would have been imposed on a Certificateholder Indemnitee had the
transactions contemplated by the Operative Documents been the sole connection
between the jurisdiction imposing such Taxes and the Certificateholder
Indemnitee with respect to which such Taxes were imposed;

            (ii) Taxes imposed on a Tax Indemnitee other than a
Certificateholder Indemnitee that are attributable to any act, event or omission
by such Tax Indemnitee that occurs after expiration or other termination of the
Facility Leases and surrender of the Facilities to the Owner Lessor or its
successors (or in the case of a Certificateholder Indemnitee, Taxes imposed for
any period after the repayment of the Lease Debt) in accordance with the
Facility Leases, (in contrast to an act, event or omission occurring prior to or
simultaneous with such expiration, termination or surrender (or, in the case of
a Certificateholder Indemnitee, such repayment)), provided that this exclusion
shall not apply so long as a Lease Event of Default shall have occurred and be
continuing;

            (iii) Taxes imposed on a Tax Indemnitee that are attributable to the
gross negligence or willful misconduct of such Tax Indemnitee, unless such
negligence or misconduct is imputed to such Tax Indemnitee solely as a result of
its participation in the transactions contemplated by the Operative Documents
and not as a result of any action or inaction by such Tax Indemnitee;

            (iv) Taxes imposed on a Tax Indemnitee arising from a breach by such
Tax Indemnitee of any of its representations, warranties or covenants under any
Operative Document except to the extent attributable to any breach by the
Facility Lessees or any other Calpine Party of any covenant, representation or
warranty contained in any Operative Document;

            (v) Taxes (A)(x) arising out of, or caused by any voluntary direct
or indirect assignment, sale, transfer or other voluntary disposition or (y) an
involuntary direct or indirect transfer or disposition resulting from a
bankruptcy or similar proceeding for relief of debtors in which such Tax
Indemnitee is a debtor or a foreclosure by a creditor of such Tax Indemnitee, in
the case of either (x) or (y),(1) by the Owner Participant of all or part of its
Member Interest, (2) by the Owner Lessor of all or part of its interest in the
Facilities or the Facility Sites, or (3) by the Indenture Trustee of any
interest in the Lease Debt or the Indenture Estate, or (4) in the case of the
Owner Lessor or the Owner Participant of any direct or indirect interest in the
Owner Lessor or the Owner Participant, in each case to the extent imposed
directly by reason of any transfer described in this clause (v)(A), or (B)
imposed after any such transfer to the extent that, under law in effect on the
date of the transfer such Taxes exceed the amount of Taxes that would be
indemnified hereunder had there been no such assignment, sale, transfer or other
voluntary disposition, unless such transfer or disposition occurs during the
continuance of a Lease Event of Default or is otherwise pursuant to the Facility
Lessees' exercise of their rights under the Operative Documents;


                                       53
   61

            (vi) Taxes imposed on a Tax Indemnitee that would not have been
imposed but for the creation or existence of any Owner Lessor's Lien or Owner
Participant's Lien attributable to such Tax Indemnitee;

            (vii) Taxes that are included as a part of the cost of the
Facilities;

            (viii) Intentionally Omitted.

            (ix) With respect to the Owner Participant, Taxes for which the
Facility Lessees are obligated to indemnify the Owner Participant under the Tax
Indemnity Agreement (or which are expressly excluded from indemnification
thereunder);

            (x) Taxes that are imposed on a Tax Indemnitee (other than a
Certificateholder Indemnitee) resulting from the Owner Lessor not being treated
as a grantor trust or other conduit entity for federal, state or local income
tax purposes, but only to the extent such Taxes exceed Taxes indemnified
hereunder that otherwise would have been imposed and are otherwise
indemnifiable;

            (xi) Taxes imposed on a Tax Indemnitee that are attributable to the
failure of such Tax Indemnitee to comply with certification, information,
documentation, reporting or other similar requirements concerning the
nationality, residence, identity or connection with the jurisdiction imposing
such Taxes; provided that the foregoing exclusion shall only apply if such
compliance is required by statute or regulation of the jurisdiction imposing
such Taxes as a precondition to relief or exemption from or reduction in such
Taxes, such Tax Indemnitee is eligible to comply with such requirement, the
Facility Lessees shall have given such Tax Indemnitee timely written notice of
such requirement and the Tax Indemnitee shall have determined in good faith that
compliance with any such requirement shall not result in any identified
non-immaterial adverse effect to its interests or to those of its Affiliates;

            (xii) Taxes consisting of interest, penalties, additions to tax or
fines resulting from a failure of such Tax Indemnitee to properly and timely
file returns as required by a taxing authority unless such failure is
attributable to the Facility Lessees not providing information that it is
expressly required to provide under the Operative Documents;

            (xiii) Taxes imposed on any Tax Indemnitee resulting from an
amendment, modification, supplement to or waiver of any provision of, any
Operative Document which amendment, modification, supplement or waiver was not
requested by or consented to by the Facility Lessees, and as to which the
Facility Lessees are not a party and the Tax Indemnitee (or, in the case of the
Owner Participant, the Owner Lessor if acting at the express direction of the
Owner Participant or any Related Party) is a party, unless such amendment,
modification, supplement or waiver (A) was required by applicable law or the
Operative Documents, (B) may be necessary or appropriate to, and is in
conformity with, any amendment to any Operative Document requested by the
Facility Lessee in writing, or (C) was consented to by a Calpine Party;

            (xiv) Taxes imposed as a result of, or in connection with, any
"prohibited transaction," within the meaning of Section 4975 of the Code,
Section 406 of ERISA or any comparable laws of any Governmental Entity, engaged
in by any Tax Indemnitee (which for this


                                       54
   62

purpose shall include any ERISA Affiliate thereof) resulting from the breach by
such Tax Indemnitee of any of its representations or warranties contained in
Section 3.4(g) or Section 8.2 of the Participation Agreement;

            (xv) Taxes to the extent such Taxes would not have been imposed on a
Tax Indemnitee if such Tax Indemnitee or any related Tax Indemnitee were a
United States Person; and

            (xvi) Taxes imposed that would not have been imposed on a Tax
Indemnitee but for the activities in the taxing jurisdiction of such Tax
Indemnitee or any Affiliate thereof unrelated to the transactions contemplated
by the Operative Documents.

        (c) Payment. Notwithstanding anything to the contrary herein and without
regard to paragraph (b) hereof, any payment by the Facility Lessees pursuant to
this Section 9.2 shall be increased by amounts necessary to ensure that all such
payments are made on an After-Tax Basis. Each payment required to be made by the
Facility Lessees to a Tax Indemnitee pursuant to this Section 9.2 shall be paid
either (i) when due directly to the applicable taxing authority by the Facility
Lessees if they are permitted to do so, or (ii) where direct payment is not
permitted, and with respect to gross up amounts, in immediately available funds
to such Tax Indemnitee by the later of (A) 10 days following the Facility
Lessees' receipt of the Tax Indemnitee's written demand for the payment pursuant
to clause (g)(i) below (which demand shall be accompanied by a written statement
of the Tax Indemnitee describing in reasonable detail the Taxes for which the
Tax Indemnitee is demanding payment and the computation of such Taxes), (B)
subject to paragraph (g) below, in the case of amounts which are being contested
pursuant to such paragraph (g), at the time and in accordance with a final
determination of such contest or (C) in the case of any indemnity demand for
which the Facility Lessees have requested review and determination pursuant to
paragraph (d) below, the completion of such review and determination; provided,
however, in no event later than the date which is one Business Day prior to the
date on which such Taxes are required to be paid to the applicable taxing
authority. Any amount payable to the Facility Lessees pursuant to paragraph (e)
or (f) below shall be paid promptly after the Tax Indemnitee realizes a Tax
Benefit giving rise to a payment under paragraph (e) or receives a refund or
credit giving rise to a payment under paragraph (f), as the case may be, and
shall be accompanied by a statement of the Tax Indemnitee computing in
reasonable detail the amount of such payment. Upon the final determination of
any contest pursuant to paragraph (g) below in respect of any Taxes for which
the Facility Lessees have made a Tax Advance, the amount of the Facility
Lessees' obligation under paragraph (a) above shall be determined as if such Tax
Advance had not been made. Any obligation of the Facility Lessees under this
Section 9.2 and the Tax Indemnitee's obligation to repay the Tax Advance will be
satisfied first by set off against each other, and any difference owing by
either party will be paid within 10 days of such final determination.

        (d) Independent Examination. Within 10 days after the Facility Lessees
receives any computation from the Tax Indemnitee, the Facility Lessees may
request in writing that an independent public accounting firm selected by the
Tax Indemnitee and reasonably acceptable to the Facility Lessees review and
determine on a confidential basis the amount of any indemnity payment by the
Facility Lessees to the Tax Indemnitee pursuant to this Section 9.2 or any
payment by a Tax Indemnitee to the Facility Lessees pursuant to paragraph (e) or
(f) below. The


                                       55
   63

Tax Indemnitee shall cooperate with such accounting firm and supply it with all
information reasonably necessary for the accounting firm to conduct such review
and determination (but not tax returns and books); provided that such accounting
firm shall agree in writing in a manner reasonably satisfactory to the Tax
Indemnitee to maintain the confidentiality of such information. The parties
hereto agree that the independent public accounting firm's sole responsibility
shall be to verify the computation of any payment pursuant to this Section 9.2
and that matters of interpretation of this Participation Agreement or any other
Operative Document are not within the scope of the independent accountant's
responsibility. The fees and disbursements of such accounting firm will be paid
by the Facility Lessees; provided that such fees and disbursements will be paid
by the Tax Indemnitee if the verification results in an adjustment in the
Facility Lessees' favor of 5 percent or more of the indemnity payment or
payments computed by the Tax Indemnitee.

        (e) Tax Benefit. If, as the result of any Taxes paid or indemnified
against by the Facility Lessees under this Section 9.2, the aggregate Taxes
actually paid by the Tax Indemnitee for any taxable year and not subject to
indemnification pursuant to this Section 9.2 are less (whether by reason of a
deduction, credit, allocation or apportionment of income or otherwise) than the
amount of such Taxes that otherwise would have been payable by such Tax
Indemnitee (a "Tax Benefit"), then to the extent such Tax Benefit was not taken
into account in determining the amount of indemnification payable by the
Facility Lessees under paragraph (a) or (c) above and provided no Significant
Lease Default or Lease Event of Default shall have occurred and be continuing
(in which event the payment provided under this Section 9.2(e) shall be deferred
until the Significant Lease Default or Lease Event of Default has been cured),
such Tax Indemnitee shall pay to the Facility Lessees the lesser of (A) (y) the
amount of such Tax Benefit, plus (z) an amount equal to any United States
federal, state or local income tax benefit resulting to the Tax Indemnitee from
the payment under clause (y) above and this clause (z) (determined using the
same assumptions as set forth in the second sentence under the definition of
After-Tax Basis) and (B) the amount of the indemnity paid pursuant to this
Section 9.2 giving rise to such Tax Benefit; provided, however, that any excess
of (A) over (B) shall be carried forward and reduce the Facility Lessees'
obligations to make subsequent payments to such Tax Indemnitee pursuant to this
Section 9.2. If it is subsequently determined that the Tax Indemnitee was not
entitled to such Tax Benefit, the portion of such Tax Benefit that is required
to be repaid or recaptured will be treated as Taxes for which the Facility
Lessees must indemnify the Tax Indemnitee pursuant to this Section 9.2 without
regard to paragraph (b) hereof.

        Notwithstanding anything to the contrary herein, each Certificateholder
Indemnitee shall determine the allocation of any tax benefits, savings, credit,
deduction or allocation in its sole good faith discretion and each position to
be taken on its tax return shall be in its sole control and it shall not be
required to disclose any tax return or related documentation to any Person.

        (f) Refund. If a Tax Indemnitee obtains a refund or credit of all or
part of any Taxes paid, reimbursed or advanced by the Facility Lessees pursuant
to this Section 9.2, the Tax Indemnitee promptly shall pay to the Facility
Lessees (x) the amount of such refund or credit (net of any Tax payable by the
Tax Indemnitee as a result of the receipt or accrual of such refund or credit)
plus (y) an amount equal to any United States federal, state or local income tax
benefit realized by such Tax Indemnitee by reason of such payment to the
Facility Lessees (determined using the same assumptions as set forth in the
second sentence under the definition of After-Tax


                                       56
   64

Basis); provided that (A) if at the time such payment is due to the Facility
Lessees a Significant Lease Default or Lease Event of Default shall have
occurred and be continuing, such amount shall not be payable until such
Significant Lease Default or Lease Event of Default has been cured, and (B) the
amount payable to the Facility Lessees pursuant to this sentence shall not
exceed the amount of the indemnity payment in respect of such refunded or
credited Taxes that was made by the Facility Lessees. Any excess of (x) and (y)
over (B) in this Section 9.2(f) shall be carried forward and reduce the Facility
Lessees' obligations to make subsequent payments to such Tax Indemnitee pursuant
to this Section 9.2. If it is subsequently determined that the Tax Indemnitee
was not entitled to such refund or credit, the portion of such refund or credit
that is required to be repaid or recaptured will be treated as Taxes for which
the Facility Lessees must indemnify the Tax Indemnitee pursuant to this Section
9.2 without regard to paragraph (b) hereof. If, in connection with a refund or
credit of all or part of any Taxes paid, reimbursed or advanced by the Facility
Lessees pursuant to this Section 9.2, a Tax Indemnitee receives an amount
representing interest on such refund or credit, the Tax Indemnitee promptly
shall pay to the Facility Lessees (1) the amount of such interest that shall be
fairly attributable to such Taxes paid, reimbursed or advanced by the Facility
Lessees prior to the receipt of such refund or credit (net of Taxes payable in
respect of the receipt or accrual of such interest) and (2) any Tax savings
resulting from payments made by the Tax Indemnitee under (1) and (2).

        (g) Contest.

            (i) Notice of Contest. If a written claim for payment is made by any
taxing authority against a Tax Indemnitee for any Taxes with respect to which
the Facility Lessees may be liable for indemnity hereunder (a "Tax Claim"), such
Tax Indemnitee shall give the Facility Lessees written notice of such Tax Claim
promptly after its receipt, and shall furnish the Facility Lessees with copies
of such Tax Claim and all other writings received from the taxing authority to
the extent relating to such claim; provided that failure to so notify the
Facility Lessees shall not relieve the Facility Lessees of any obligation to
indemnify the Tax Indemnitee hereunder except to the extent that such failure
effectively precludes the ability to conduct a contest hereunder (and without
limiting any damage claim or remedy the Facility Lessees may otherwise have for
such failure).

            (ii) Control of Contest. Subject to subsection (g)(iii) below, the
Facility Lessee will be entitled to contest (acting through counsel selected by
the Facility Lessees and reasonably satisfactory to the Tax Indemnitee), and
control the contest of, any Tax Claim if (A) such Tax Claim may be pursued in
the name of the Facility Lessees and may be segregated procedurally from tax
claims for which the Facility Lessees are not obligated to indemnify the Tax
Indemnitee or (B) the Tax Indemnitee requests that the Facility Lessees control
such contest. In the case of all other Tax Claims, the Tax Indemnitee will
contest the Tax Claim if the Facility Lessees shall request that the Tax be
contested (subject to subsection (g)(iii) below), and the following rules shall
apply with respect to such contest:

                 (1) the Tax Indemnitee will control the contest of such Tax
Claim (acting through counsel selected by the Tax Indemnitee and reasonably
satisfactory to the Facility Lessees) at the Facility Lessees' expense,


                                       57
   65

                 (2) the decisions regarding what actions to be taken shall be
made by the Tax Indemnitee in its sole judgment, and

                 (3) the Tax Indemnitee shall not otherwise settle, compromise
or abandon such contest without the Facility Lessees' prior written consent
except as provided in paragraph (g)(iv) below.

        In either case, the party conducting such contest shall consult in good
faith with the other party and its designated counsel with respect to such Tax
Claim and shall provide the other party with copies of any reports or claims (or
extracts therefrom) issued by the relevant auditing agents or taxing authority
relating to such Tax Claim.

            (iii) Conditions of Contest. Notwithstanding the foregoing, no
contest with respect to a Tax Claim will be required or permitted pursuant to
this Section 9.2, and the Facility Lessees shall be required to pay the
applicable Taxes without contest, unless:

                 (1) within 30 days after written notice by the Tax Indemnitee
to the Facility Lessees of such Tax Claim (or such shorter period, to be
specified by the Tax Indemnitee in such notice, as required for taking action
with respect to such Tax Claim), the Facility Lessees shall request in writing
to the Tax Indemnitee that such Tax Claim be contested,

                 (2) no Significant Lease Default or Lease Event of Default has
occurred and is continuing, unless the Facility Lessees have provided security
for the indemnity payment and the expenses of contest in a manner reasonably
acceptable to the Tax Indemnitee, both as to coverage and credit,

                 (3) there is no risk of sale, forfeiture or loss of, or the
creation of any Lien on any Facilities, the Facility Sites, or any portion or
Component thereof or any interest therein as a result of such Tax Claim;
provided that this clause (3) shall not apply if the Facility Lessees post
security satisfactory to the Tax Indemnitee, both as to coverage and credit, in
its sole discretion,

                 (4) there is no risk of imposition of any criminal penalties or
liabilities,

                 (5) if such contest involves payment of such Tax, the Facility
Lessees will advance such amount necessary to pay the Tax to the Tax Indemnitee
or its Affiliates on an interest-free basis and with no after-tax cost to such
Tax Indemnitee (a "Tax Advance"),

                 (6) The Facility Lessees agree to pay (and pays on demand) and
with no after-tax cost to such Tax Indemnitee or its Affiliates all reasonable
costs, losses and expenses incurred by the Tax Indemnitee in connection with the
contest of such claim (including, without limitation, all reasonable legal,
accounting and investigatory fees and disbursements and penalties, interest and
additions to tax),

                 (7) the Tax Indemnitee has been provided at the Facility
Lessees' sole expense with an opinion, reasonably acceptable to such Tax
Indemnitee, of independent tax counsel selected by the Tax Indemnitee and
reasonably acceptable to the Facility Lessees to the effect that there is a
Reasonable Basis for contesting such Tax Claim,


                                       58
   66

                 (8) in the case of a judicial appeal, the appeal is not to the
U.S. Supreme Court,

                 (9) if such contest is controlled by the Facility Lessees,
prior to commencement of a judicial action with respect to the contest, the
Facility Lessees shall have admitted in writing its liability to pay an
indemnity pursuant to this Section 9.2 with respect to such Tax, which admission
shall be binding on the Facility Lessees unless and to the extent such contest
is determined in a manner that conclusively demonstrates that the Facility
Lessees are not so liable,

                 (10) if the amount of Taxes at issue is in excess of $20,000,
and

                 (11) if the subject matter of such claim shall be of a
continuing or recurring nature and shall have previously been decided pursuant
to this paragraph (g), there shall have been a change in law after such
previously decided claim and such Tax Indemnitee receives, at the Facility
Lessees' sole cost, an opinion of counsel selected by such Tax Indemnitee and
reasonably acceptable to the Facility Lessees to the effect that such change is
favorable to the position asserted in the previous contest.

            (iv) Waiver of Indemnification. Notwithstanding anything to the
contrary contained in this Section 9.2, the Tax Indemnitee at any time may elect
to decline to take any action or any further action with respect to (and the
Facility Lessees shall not be permitted to contest) a Tax Claim and may in its
sole discretion settle or compromise any contest with respect to such Tax Claim
without the Facility Lessees' consent if the Tax Indemnitee:

                 (1) waives its right to any indemnity payment by the Facility
Lessees pursuant to this Section 9.2 in respect of such Tax Claim (and any other
claim for Taxes with respect to any other taxable year the contest of which is
effectively precluded by the Tax Indemnitee's declination to take action with
respect to the Tax Claim), and

                 (2) promptly repays to the Facility Lessees any Tax Advance and
any amount paid to such Tax Indemnitee under Section 9.2(a) above in respect of
such Taxes, but not any costs or expenses with respect to any such contest.

        Except as provided in the preceding sentence, any such waiver shall be
without prejudice to the rights of the Tax Indemnitee with respect to any other
Tax Claim.

        (h)    Reports.

               (i) If any report, statement or return is required to be filed by
a Tax Indemnitee with respect to any Tax that is subject to indemnification
under this Section 9.2, the Facility Lessees will (1) notify the Tax Indemnitee
in writing of such requirement not later than 30 days prior to the date such
report, statement or return is required to be filed (determined without regard
to extensions) and (2) either (y) unless directed by the Tax Indemnitee
otherwise, if permitted by applicable law, prepare such report, statement or
return for filing by the Facility Lessees in such manner as will show the
ownership of the Facilities by the Owner Lessor for United States federal, state
and local income tax purposes (if applicable), send a copy of such report,
statement or return to the Tax Indemnitee and timely file such report, statement
or return


                                       59
   67

with the appropriate taxing authority, or (z) in all other cases, prepare and
furnish to such Tax Indemnitee not later than 30 days prior to the date such
report, statement or return is required to be filed (determined without regard
to extensions) a proposed form of such report, statement or return for filing by
the Tax Indemnitee; provided that the only consequence for failure to file after
compliance by the Facility Lessees with the requirements hereof shall be a loss
of indemnification from the Facility Lessees in respect of any Tax to the extent
resulting from such failure.

            (ii) Each of the Tax Indemnitee and the Facility Lessees, as the
case may be, will timely provide the other, at the Facility Lessees' expense,
with all information in its possession that the other party may reasonably
require and request to satisfy its tax filing obligations.

        (i) Non-Parties. If a Tax Indemnitee is not a party to this Agreement,
the Facility Lessees may require such Tax Indemnitee to agree in writing, in a
form reasonably acceptable to the Facility Lessees, to the terms of this Section
9.2 prior to making any payment to such Tax Indemnitee under this Section.
Subject to the preceding sentence, the Facility Lessees' obligations under this
Section 9.2 shall inure to the benefit of each and every Tax Indemnitee without
regard to whether such Tax Indemnitee is a party to this Agreement.


SECTION 10. FACILITY LESSEE'S RIGHT OF QUIET ENJOYMENT

        Each party to this Agreement acknowledges notice of, and consents in all
respects to, the terms of the Facility Leases and the Facility Site Subleases
and expressly, severally and as to its own actions only, agrees that, so long as
no Lease Event of Default has occurred and is continuing, it shall not take or
cause to be taken any action or direct that any action be taken, which is
contrary to or inconsistent with any Facility Lessee's rights under its Facility
Lease and Facility Site Sublease, including the right to possession, use and
quiet enjoyment of such Facility, Easements and Facility Site.


SECTION 11. SUPPLEMENTAL FINANCING IMPROVEMENTS; OPTIONAL REFINANCINGS

        Section 11.1. Financing Improvements. Upon the request of a Facility
Lessee delivered at least 90 days prior to financing a portion of the cost of
any Improvement, the Owner Lessor and the Indenture Trustee agree to cooperate
with such Facility Lessee to (a) issue Additional Lessor Notes under the
Collateral Trust Indenture to finance such Improvement which will rank pari
passu with the applicable Lessor Notes and/or any applicable Additional Lessor
Notes then outstanding; (b) execute and deliver one or more supplements to the
Collateral Trust Indenture for purpose of subjecting the Owner Lessor's interest
in any such Improvements to the Liens thereof, and (c) execute and deliver an
amendment to the applicable Facility Lease to reflect the adjustments required
by clause (iv) below; provided, however, that (x) the Owner Participant shall
have been given the opportunity, but shall have no obligation, to provide all or
part of the funds required to finance any such Improvement by making an
Additional Equity Investment in such amount, if any, as it may determine in its
sole and absolute discretion, but such Facility Lessee shall have no obligation
to accept such Additional Equity Investment; and (y) the


                                       60
   68

conditions set forth below and in Section 2.12 of the Collateral Trust Indenture
shall have been satisfied. The obligation to finance such Improvements through
the issuance of Additional Lessor Notes under Section 2.12 of the Collateral
Trust Indenture (any financing of Improvements through the issuance of such
Additional Lessor Notes under the Collateral Trust Indenture being called a
"Supplemental Financing") is subject to the following additional conditions:

            (i) there shall be no more than one such financing in any calendar
year;

            (ii) the applicable Additional Lessor Notes (A) shall have a final
maturity no later than the final maturity of the Lessor Notes issued on the
Closing Date and (B) will be fully repaid out of additional Basic Rent, as
adjusted pursuant to the applicable Facility Lease, during the Facility Lease
Term;

            (iii) the applicable Additional Lessor Notes shall have an average
life to maturity equal to the average life to maturity of the Lessor Notes
issued on the Closing Date;

            (iv) appropriate adjustments to Basic Rent and Termination Value
(determined without regard to any tax benefits associated with such
Improvements, unless the Owner Participant is making an Additional Equity
Investment) shall be made to protect the Owner Participant's Net Economic
Return;

            (v) the applicable Facility Lessee shall have paid, on an After-Tax
Basis, all reasonable costs and expenses of the Transaction Parties, including
the reasonable fees and expenses of counsel to the Owner Participant, the Owner
Lessor, the Indenture Trustee, the Lease Indenture Company, the Pass Through
Company and the Pass Through Trustee, in each case to the extent incurred in
connection with any financing or refinancing pursuant to this Section 11 whether
or not the financing is consummated;

            (vi) no Significant Lease Default or Lease Event of Default shall
have occurred and be continuing unless the Improvements to be constructed with
the proceeds of the applicable Additional Lessor Notes shall cure such
Significant Lease Default or Lease Event of Default and such Improvements shall
be made in compliance with the Operative Documents;

            (vii) such Additional Lessor Notes represent an aggregate amount not
less than $20 million, nor greater than 100% of the costs of the Improvements
being financed; provided that the aggregate balance of the Notes for such
Facility never exceeds 80% of the fair market value (which fair market value
shall be determined by an appraiser selected by the Facility Lessees and
reasonably acceptable to the Owner Participant) of such Facility taking into
account the fair market value of such Improvements;

            (viii) the Owner Participant shall have received a favorable opinion
of its tax counsel satisfactory to such Owner Participant to the effect that
such financing creates no incremental tax risk not indemnified to the Owner
Participant's satisfaction (including additional indebtedness incurred to
finance the Improvements not constituting "qualified nonrecourse indebtedness"
within the meaning of Treasury Regulations Section 1-861-10T(b));


                                       61
   69

            (ix) the Owner Participant shall suffer no adverse accounting
effects under GAAP as a result of such financing;

            (x) the Facility Lessees shall have made or delivered such
representations, warranties, covenants, opinions or certificates as the Owner
Participant, the Indenture Trustee may reasonably request;

            (xi) the applicable Facility Lessee or the Guarantor shall have, at
such time, a credit rating of at least investment grade from S&P and Moody's;

            (xii) the applicable Facility Lessee shall pay to (a) the Owner
Participant a fee of $100,000 and (b) the Pass Through Trustee for the benefit
of the Certificateholders, to be shared by such Certificateholders on a pro rata
basis, a fee of $100,000 for each such financing, in each case other than the
first financing; and

            (xiii) Calpine shall have affirmed to the Transaction Parties that
the Calpine Guaranties cover the additional indebtedness contemplated by this
Section 11.1.

        Notwithstanding the prior provision dealing with the financing of
Improvements through the Facility Leases, the Facility Lessees shall at all
times have the right to fund Improvements to the Facilities other than through
the Facility Leases; provided that Required Improvements and non-Severable
Improvements may only be financed other than through the Facility Leases on an
unsecured basis. Notwithstanding any of the foregoing of this Section 11.1,
except for Required Improvements and Improvements relating to pollution control,
no Improvement shall materially decrease the value, residual value, utility or
remaining useful life of such Facility immediately prior to such Improvement or
cause such Facility to become limited-use property.

        Section 11.2. Optional Refinancing of Lease Debt. Each Facility Lessee
shall have the right, exercisable at any time on no more than three occasions,
to request the Owner Lessor (and the Owner Lessor shall reasonably consider and
not unreasonably withhold its consent), to refund or refinance the Lease Debt
(and all Certificates then outstanding), in whole but not in part, through the
issuance of Additional Lessor Notes; provided that all conditions to the
issuance of such Additional Lessor Notes contained in Section 2.12 of the
Collateral Trust Indenture shall have been satisfied and all applicable
Make-Whole Amounts shall have been paid. Any refinancing under this Section 11.2
shall also be subject to satisfaction of the following additional conditions:

            (i) the Owner Lessor shall be able to issue and sell such debt in an
amount adequate to accomplish such refunding or refinancing;

            (ii) such Additional Lessor Notes shall have a final maturity no
later than the final maturity date of the Lessor Notes issued on the Closing
Date and will be fully repaid out of Basic Rent during the Facility Lease Term;

            (iii) appropriate adjustments to Basic Rent and Termination Value
shall be made to protect the Owner Participant's Net Economic Return; provided
that no adjustments shall be made to the amortization schedule;


                                       62
   70

            (iv) no Significant Lease Default or Lease Event of Default shall
have occurred and be continuing;

            (v) the Owner Participant shall suffer no adverse accounting effects
under GAAP;

            (vi) such Facility Lessee shall have made or delivered such
representations, warranties, covenants, opinions and certificates as the Owner
Participant may reasonably request, which representations, warranties, covenants
and agreements shall be of no greater scope than those provided by such Facility
Lessee under the Operative Documents to which it is a party (except to the
extent necessitated by differences between existing Operative Documents and the
terms and conditions of the proposed refinancing);

            (vii) all documentation in connection with such refinancing shall be
reasonably satisfactory to the Owner Lessor and the Owner Participant;

            (viii) the Owner Participant shall receive a consent fee of $100,000
in the aggregate for each refinancing after the first such refinancing;

            (ix) the Lease Debt as financed constitutes qualified nonrecourse
indebtedness within the meaning of Treasury Regulations Section 1-861-10T(b) and
the Owner Participant shall have received an opinion satisfactory to it to such
effect; and

            (x) the Owner Participant shall receive an opinion satisfactory to
it that the refinancing (as opposed to the right to request such refinancing)
shall not result in any incremental tax risk not indemnified to the Owner
Participant's satisfaction.

        Calpine shall have affirmed in writing to the Transaction Parties that
the Calpine Guaranties cover the additional indebtedness contemplated by this
Section 11.1.

        Section 11.3. Cooperation. The Owner Participant will cooperate with and
assist the Facility Lessees in connection with any refinancing and/or assumption
of the Lease Debt, so long as such refinancing and/or assumption of the Lease
Debt is in accordance with the terms of the Operative Documents. The Owner
Participant will execute such agreements and documents as may be necessary with
respect to any such refinancing and will instruct the Owner Lessor to act
accordingly.


SECTION 12. CERTAIN ADJUSTMENTS TO PERIODIC RENT AND TERMINATION VALUE

        (a) Prior to or on the Closing Date, Periodic Rent and Termination Value
shall be adjusted, either upward or downward, in accordance with the Facility
Leases:

            (i) at the request of a Facility Lessee, to re-optimize the Lease
Debt; provided such re-optimization shall not adversely affect the Owner Lessor
or the Owner Participant;


                                       63
   71

            (ii) at the request of a Facility Lessee or the Owner Participant,
to reflect any changes in the Pricing Assumptions, including, without
limitation, (x) the initial interest rate on any of the applicable Lessor Notes
which is different from the applicable interest rate set forth in the Pricing
Assumptions, (y) an increase in the Transaction Costs from the amount assumed in
the Pricing Assumptions, unless the Facility Lessees have elected to pay such
increase, and (z) a Closing Date other than the Scheduled Closing Date; and

            (iii) at the request of a Facility Lessee or the Owner Participant
to reflect any enactment, promulgation, release or adoption of, amendment to or
change in the Code, Treasury Regulations, Revenue Rulings or Revenue Procedures
("Tax Law Change") enacted prior to the Closing;

provided that if any adjustment required by this paragraph (a) would result in
(i) a Facility Lease not qualifying as an operating lease for a Facility Lessee
under FASB 13 or FASB 98, or (ii) the aggregate of all rent adjustments made on
or before, or contemplated to be made on, the Closing Date (other than
adjustments to reflect a change in Transaction Costs or the actual interest rate
of the Certificates) shall cause either (x) the after-tax net present value of
Basic Rent discounted at 6% to increase by more than 100 basis points or (y) the
total Basic Rent to increase by more than 2%, then in either such case, the
Facility Lessees shall not be obligated to close the Overall Transaction.

        (b) After the Closing Date, Periodic Rent and Termination Value, as well
as the coverage under the Qualifying Letter of Credit, shall be adjusted at the
request of a Facility Lessee or the Owner Participant in accordance with the
terms of the related Facility Lease to which it is a party.

        (c) Any adjustment pursuant to this Section 12 shall be calculated (A)
to preserve the Owner Participant's Net Economic Return through the Basic Lease
Term and (B) to the extent consistent with (A) above, to maintain operating
lease treatment for each Facility Lessee; provided, however, that to the extent
consistent with preserving the Owner Participant's Net Economic Return, all
adjustments shall at the option of the Facility Lessees be calculated to (x)
minimize the average annual Periodic Rent over the Basic Lease Term for the
Facility Lessees' GAAP accounting purposes and/or (y) minimize the present value
to each Facility Lessee of Periodic Rent; and provided, further, that no such
adjustment shall require the Owner Participant to record a loss as of the date
such adjustment is made. Adjustments will be computed by the Owner Participant
based upon the Pricing Assumptions and the Tax Assumptions originally used to
calculate the Basic Rent and Termination Value. Adjustments made pursuant to
this Section 12 shall be subject to verification as provided in Section 3.4 of
each Facility Lease.


SECTION 13. TRANSFER OF THE FACILITY LESSEE OWNERSHIP

        Section 13.1. Transfer of the Facility Lessee Ownership.

        (a) Each Facility Lessee covenants and agrees that it shall not during

SECTION 14. MISCELLANEOUS

        Section 14.1. Consents; Cooperation. The Owner Participant covenants and
agrees that it shall not unreasonably withhold its consent to any consent
requested of the Owner Lessor under the terms of the Operative Documents that by
its terms is not to be unreasonably withheld by the Owner Lessor.

        Section 14.2 Successor Owner Lessor. The parties hereto agree that the
transfer or assignment pursuant to the terms of the LLC Agreement by the Owner
Lessor to a successor Owner Lessor, will not violate the terms of any Operative
Document.

        Section 14.3. Bankruptcy of Lessor Estate. If (i) all or any part of the
Lessor Estate becomes the property of a debtor subject to the reorganization
provisions of Title 11 of the United States Code, as amended from time to time,
(ii) pursuant to such reorganization provisions the Owner Participant is
required, by reason of the Owner Participant being held to have recourse
liability to the debtor or the trustee of the debtor directly or indirectly, to
make payment on account of any amount payable as principal or interest on the
Lessor Notes, and (iii) the Indenture Trustee actually receives any Excess
Amount, as defined below, which reflects any payment by the Owner Participant on
account of clause (ii) above, the Indenture Trustee upon written request of the
Owner Participant shall promptly refund to the Owner Participant such Excess
Amount (and, to the extent so refunded, such amount owing under the Lessor Notes
shall be reinstated). For purposes of this Section 14.3, "Excess Amount" means
the amount by which such payment exceeds the amount which would have been
received by the Indenture Trustee if the Owner Participant had not become
subject to the recourse liability referred to in clause (ii) above, as stated in
the Owner Participant's written request to the Indenture Trustee. Nothing
contained in this Section 14.3 shall prevent the Indenture Trustee from
enforcing any personal recourse obligations (and retaining the proceeds thereof)
of the Owner Participant as contemplated by this Participation Agreement (other
than referred to in clause (ii)).

        Section 14.4. Waivers. No term, covenant, agreement or condition of this
Agreement may be terminated, amended or compliance therewith waived (either
generally or in a particular instance, retroactively or prospectively) except by
an instrument or instruments in writing executed by each party hereto.

        Section 14.5. Notices. Unless otherwise expressly specified or permitted
by the terms hereof, all communications and notices provided for herein shall be
in writing or by a telecommunications device capable of creating a written
record, and any such notice shall become effective (a) upon personal delivery
thereof, including, without limitation, by overnight mail or courier service,
(b) in the case of notice by United States mail, certified or registered,
postage prepaid, return receipt requested, upon receipt thereof, or (c) in the
case of notice by such a telecommunications device, upon transmission thereof;
provided such transmission is promptly confirmed by either of the methods set
forth in clauses (a) or (b) above, in each case addressed to each party hereto
at its address set forth below or, in the case of any such party hereto, at such
other address as such party may from time to time designate by written notice to
the other parties hereto:

        Section 14.13. Limitation of Liability

        (a) None of the Owner Participant, the Owner Lessor, the Indenture
Trustee, the Lease Indenture Company, the Pass Through Trustee, the Pass Through
Trustee Company or the Certificateholders shall have any obligation or duty to
the Facility Lessees or to others with respect to the transactions contemplated
hereby, except those obligations or duties expressly set forth in this Agreement
and the other Operative Documents to which such Person is a party, and none of
the Owner Participant, the Owner Lessor, the Indenture Trustee, the Lease
Indenture Company, the Pass Through Trustee, the Pass Through Company or the
Certificateholders shall be liable for performance by any other party hereto of
such other party's obligations or duties hereunder. Without limitation of the
generality of the foregoing, under no circumstances whatsoever shall the Owner
Participant be liable to the Facility Lessees for any action or inaction on the
part of the Owner Lessor in connection with the transactions contemplated
herein, whether or not such action or inaction is caused by willful misconduct
or gross negligence of the Owner Lessor, unless such action or inaction is at
the written direction of the Owner Participant.

        (b) Neither Facility Lessee or any other Calpine Party shall have any
obligation or duty to the Owner Participant, the Owner Lessor, the Indenture
Trustee, the Lease Indenture Company, the Pass Through Trustee, the Pass Through
Company, the Certificateholders or to others with respect to the transactions

such other party's obligations or duties hereunder.

        (c) The Lease Indenture Company and the Pass Through Company are
entering into the Operative Documents to which it is a party solely as trustees
under the Collateral Trust Indenture and the Pass Through Trust Agreement,
respectively, and not in their individual capacities, except as expressly
provided herein or therein, and in no case whatsoever shall the Lease Indenture
Company and the Pass Through Company be personally liable for, or for any loss
in respect of, any of the statements, representations, warranties, agreements or
obligations of the Owner Lessor hereunder or under any other Operative Document,
as to all of which the other parties hereto agree to look solely to the
Indenture Estate and the Lessor Estate, respectively; provided, however, that
the Lease Indenture Company and the Pass Through Trust Company shall be liable
hereunder for their own negligence or willful misconduct or for a breach of
their representations, warranties and covenants made in their individual
capacity under any Operative Document.

        (d) The right of the Indenture Trustee or the Pass Through Trustee to
perform any discretionary act enumerated herein or in any other Operative
Document (including, without limitation, the right to consent to any action
which requires their consent and the right to waive any provision of, or consent
to any change or amendment to, any of the Operative Documents) shall not be
construed as a duty, and neither the Indenture Trustee nor the Pass Through
Trustee shall be liable or answerable for other than its negligence or willful
misconduct in the performance of such acts. In connection with any such
discretionary acts, the Indenture Trustee may in its sole discretion (but shall
not, except as otherwise provided herein or in the Collateral Trust Indenture or
as otherwise required by Applicable Law, have any obligation to) request the


                                       71
   79

approval or instruction of the Pass Through Trustee as the holder of the Lessor
Notes, and the Pass Through Trustee may in its sole discretion (but shall not,
except as otherwise provided in the Operative Documents or as otherwise required
by Applicable Law, have any obligation to) request the approval of the
Certificateholders.

        (e) The Owner Participant will give the Facility Lessees at least 15
days' prior notice of any proposed amendment or supplement to the LLC Agreement
(other than an amendment solely effecting a transfer of the Owner Participant's
interest in the Lessor Estate) and deliver true, complete and fully executed
copies to the Facility Lessees of any amendment or supplement to the LLC
Agreement. No amendment or supplement to the LLC Agreement that would reasonably
be expected to materially adversely affect the interests of the Facility Lessees
or the Indenture Trustee shall become effective without the written consent of
the Indenture Trustee and the Facility Lessees.

Operative Documents, or the subject matter hereof or thereof may not be enforced
in or by such court.

        (b) TO THE EXTENT PERMITTED BY APPLICABLE LAW, EACH OF THE PARTIES

duly execute and deliver such further documents to make such further assurances

nothing contained in this Participation Agreement or any other Operative
Document shall be deemed or construed to create a partnership, joint venture or
other co-ownership arrangement by and among any of them.

        Section 14.18. Entire Agreement. This Agreement, together with the other
applicable Operative Documents, constitutes the entire agreement of the parties
hereto and thereto with respect to the subject matter hereof and thereof and
supersedes all oral and all prior written agreements and understandings with
respect to such subject matter; provided that, notwithstanding the foregoing,
the obligations of Calpine with respect to fees, expenses and indemnifications
set forth in the letter agreement, dated October 16, 2000 between Calpine and
CSFB shall not be superceded hereby and shall remain in full force and effect.

        Section 14.19. Public Utility Regulation The Facility Lessees, the Owner
Lessor and the Owner Participant agree to cooperate and to take reasonable
measures to alleviate the source or consequence of any regulation constituting a

of the Facility Lessees, so long as there shall be no adverse consequences to
the Owner Lessor or the Owner Participant as the result of such cooperation or
taking of reasonable measures.

        Section 14.21. Confidentiality of Information. Each of the parties
hereto agrees that any information (x) contained herein or in the other
Operative Documents (including any terms, conditions, agreements, financial
projections, and other financial and operating information contained herein or
therein, and the terms of any insurance policies required or otherwise
maintained pursuant hereto), (y) disclosed or to be disclosed by one such party
to another such party (for purposes of this Section 14.21, each of the parties
to this Agreement being referred to herein as a "Receiving Party") in connection
with this Agreement or any other Operative Document, or (z) otherwise received
in connection with this Agreement or any other Operative Document (or the
transactions contemplated thereby) and designated by the disclosing party in
writing as confidential, shall, in each case, be kept confidential by the
Receiving Party and shall not be used otherwise than in connection with the
business of the Parties contemplated hereunder except:

        (a) to the extent such information is generally available to the public
prior to the Receiving Party's receipt thereof, or which becomes public after
such receipt, but through no violation by such Receiving Party of this Section
14.21;

        (b) as may be required by Applicable Law or, upon prompt prior written
notice to the affected party, by judicial process;

        (c) as may be independently developed by the Receiving Party other than
in connection with the transactions contemplated hereby with respect to the
Facilities or the Facility Sites;

        (d) as may be disclosed to counsel, auditors or accountants to the
Receiving Party, or to the National Association of Insurance Commissioners;

        (e) to the extent used in connection with any litigation to which the
Receiving Party is a party, provided that the other parties hereto shall have
been given prompt prior written notice (to the extent permitted by law) of such
proposed disclosure;

        (f) as may be disclosed to any transferee or proposed transferee of the
Receiving Party; provided, however, that, prior to any such disclosure, any such
transferee or proposed transferee, as the case may be, shall have agreed in
writing to be bound by the terms of this Section 14.20; or

        (g) as may be necessary or desirable in connection with the enforcement
of remedies by any party to any of the Operative Documents.

        The foregoing obligation as to confidentiality and non-use shall survive
the termination of this Agreement for a period of five years.

        Section 14.22. Reliance. Calpine and the Facility Lessees agree that the
Transaction Parties may rely on the Environmental Reports.

        Section 14.23. Intentionally Omitted

        Section 14.24. Amendments, Etc. No Operative Document nor any of the
terms thereof (including the terms of this Section 14.24) may be terminated,
amended, supplemented, waived or modified, except by an instrument in writing
(a) signed in the case of a waiver, by the party against which enforcement of
such waiver is sought, and no such waiver shall become effective unless signed
copies thereof shall have been delivered to each such party or (b) in the case
of termination, amendments, supplements or modifications, consented to by all
parties hereto; provided, however, that the consent of the Facility Lessees is
not required in the case of amendments to any Operative Document to which the
Facility Lessees are not a party and which would not increase or accelerate the
Facility Lessees' or the Guarantor's obligations under any of the Operative
Documents nor impair the Facility Lessees' or the Guarantor's rights under any
of the Operative Documents; provided further, that the consent of the Facility
Lessees, the Indenture Trustee or the Pass Through Trustee shall not be required
(but the consent of the Guarantor shall be so required) for the amendment,
termination, replacement, supplement, waiver or modification of any Qualifying
Letter of Credit. Notwithstanding the foregoing, Section 5.6 of the Collateral
Trust Indenture shall not be amended without the Guarantor's consent.

        Section 14.25. Credit for Certain Disbursements. Notwithstanding any
other provision of this Agreement or any provision of any other Operative
Document, any payment to the Owner Participant under a Qualified Letter of
Credit (exclusive of any deposit into the Equity Collateral Account) or from the
Equity Collateral Account shall reduce, dollar-for-dollar, the obligation of the
Guarantor under the Calpine Guaranty (Tiverton), on the one hand, and the
Guarantor under the Calpine Guaranty (Rumford), on the other hand, the aggregate
amount of such reductions to be allocated between the respective amounts of the
Equity Portion of Termination Value applicable, on the date of such reduction,
to the Calpine Guaranty (Tiverton) and to the Calpine Guaranty (Rumford),
respectively. Upon the reduction referred to in the prior sentence becoming
effective, comparable and parallel reductions will automatically be made in the
Termination Values specified in the Facility Leases.
