               (b) The Guarantor agrees that upon the occurrence and during the
continuance of a Lease Event of Default, it (1) shall pay to the Owner Lessor

shall make such payment notwithstanding the fact that, pursuant to Section 17.1
of the Rumford Facility Lease, such amounts might not otherwise be payable by
the Lessee. The Guarantor's obligations in this Section 2.1(b) are direct and
primary obligations (and not obligations of a guarantor or surety) of the
Guarantor to the Owner Lessor and the Indenture Trustee (as assignee of the
Owner Lessor), which shall not be affected in any way by the provisions of
Section 2.1(a) above or any payments under any other Operative Documents of any

Trustee under this Guaranty with respect to the Debt Portion of Termination
Value and the Equity Portion of Termination Value shall first be applied to
satisfy the indebtedness evidenced by the Lessor Notes before being applied to
satisfy any claim in respect of the amounts and Overdue Interest referred to in
the preceding clause (B).

               (d) Notwithstanding anything herein or in the Collateral Trust
Indenture to the contrary, in the event that an Indenture Event of Default that
is attributable to a Lease Event of Default has occurred and is continuing and
the Indenture Trustee (as assignee of the Owner Trustee) forecloses upon and
sells, assigns or otherwise transfers, its interest in this Guaranty pursuant to
the provisions of the Collateral Trust Indenture, the Guarantor shall remain
obligated hereunder to pay to the Owner Lessor an amount equal to the amounts
referred to in Section 2.1(a)(3) and Section 2.1(b)(1) (but without

not a claim for the Equity Portion of Termination Value (Rumford) and the Equity
Portion of Periodic Rent (Rumford).

               Section 2.2. In the case of any failure by the Rumford Lessee to
perform and observe any term, provision or condition referred to in Section
2.1(a) when due pursuant to the Operative Documents, the Guarantor agrees to
cause such performance or observance to be done, and in the case of any failure
by the Rumford Lessee to make such payment as and when the same shall become due
and payable (by acceleration or otherwise), the Guarantor hereby agrees to make
such payment (and, in addition, such further amounts, if any, as shall be
sufficient to cover the costs and expenses of collection hereunder) as and when
such payment is due and payable.

               All obligations and indebtedness set forth in Section 2.1 above,

are direct, independent, and primary obligations of the Guarantor and are
absolute, present, unconditional and continuing obligations and are not
conditioned in any way upon the institution of suit or the taking of any other
action or any attempt to enforce performance of or compliance with the

the Rumford Lessee and shall constitute a guaranty of, and agreement with
respect to, payment and performance and not a guaranty of collection, binding

and effect and irrevocable without regard to the genuineness, validity, legality
or enforceability of the Participation Agreement, the Rumford Facility Lease,
the Tax Indemnity Agreement or any other agreement (including any other Rumford

        in the Participation Agreement and in any preliminary or final offering
        circular distributed in accordance with the terms of the Rumford
        Operative Documents) for purposes of or in connection with the Calpine
        Documents or any transaction contemplated therein is true and accurate
        in all material respects on the date as of which such information is
        dated or



                                       8
   11

        certified and not incomplete by omitting to state any fact necessary to
        make such information relating to the Guarantor (taken as a whole) not
        misleading in any material respect at such time in light of the
        circumstances under which such information was provided; 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
        Guarantor, or (ii) the descriptions of the Rumford Operative Documents
        or the tax consequences to beneficial owners of Certificates; provided,
        however, each of the Beneficiaries acknowledges 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 neither of the Facility
        Lessees makes any 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.

               (xii) The Guarantor is in compliance with all applicable
        statutes, regulations and orders of, and all applicable restrictions
        imposed by, all governmental bodies, domestic or foreign, in respect of
        the conduct of its business and the ownership of its property (including
        applicable statutes, regulations, orders and restrictions relating to
        environmental standards and controls), except such noncompliance as
        would not, in the aggregate, have a material adverse effect on the
        business, operations, property, assets or condition (financial or
        otherwise) of the Guarantor, or the Guarantor's ability to perform its
        obligations under the Calpine Documents.

               (xiii) The Guarantor has filed all tax returns and reports
        required by law to have been filed by it and has paid all taxes and
        governmental charges thereby shown to be owing (other than any such
        taxes or charges which are being diligently contested in good faith by
        appropriate proceedings and for which adequate reserves in accordance
        with GAAP shall have been set aside on its books), except such
        non-filing or non-payment, as the case may be, as would not, in the
        aggregate, have a material adverse effect on the business, operations,
        property, assets or condition (financial or otherwise) of the Guarantor.

               (xiv) No default has occurred under this Guaranty, which default
        would reasonably be expected to result in a material adverse effect on
        the business, operations, assets or condition (financial or otherwise)
        of the Guarantor.

               (xv) In accordance with Section 8.12 hereof and Section 14.04 of
        the Participation Agreement, the Guarantor has validly submitted to the
        jurisdiction of the Supreme Court of the State of New York, New York
        County and the United States District Court for the Southern District of

               Section 3.2. The Guarantor covenants and agrees that on and after
the date hereof and until this Guaranty is terminated pursuant to the terms
hereof the Guarantor shall:

               (a) file with the Owner Participant and the Indenture Trustee,
within 15 days after the filing with the SEC, copies of the annual reports and
of the information, documents and other reports (or copies of such portions of
any of the foregoing as the SEC may by rules and regulations prescribe) which
the Guarantor is required to file with the SEC pursuant to Section 13 or 15(d)
of the Exchange Act. In the event the Guarantor is at any time no longer subject
to the reporting requirements of Section 13 or 15(d) of the Exchange Act, it
shall file with the Owner Participant, and for so long as the Certificates
remain outstanding, the Indenture Trustee and the Pass Through Trustee, within
15 days after the Guarantor would have been required to file such documents with
the SEC, copies of the annual reports and of the information, documents and
other reports which the Guarantor would have been required to file with the SEC
if the Guarantor had continued to be subject to such Sections 13 or 15(d).
Delivery of such reports, information and documents to the Owner Participant,
the Indenture Trustee and the Pass Through Trustee is for informational purposes
only and their receipt of the same shall not constitute constructive notice of
any information contained therein or determinable from information contained
therein, including the Guarantor's compliance with any of its covenants
hereunder (as to which the Owner Participant, the Indenture Trustee and the Pass
Through Trustee are entitled to rely exclusively on Officers' Certificates);

               (b) furnish to the Beneficiaries, promptly upon the Guarantor
obtaining Actual Knowledge of any action, suit or proceeding pending or
threatened against the Guarantor before any court or before any governmental
department, commission or agency or any arbitrator, which in the Guarantor's
good faith opinion would reasonably be likely to result in a material adverse
effect on the business, operations, property, assets or condition (financial or
otherwise) of the Guarantor, a certificate of a senior officer specifying the
nature of such action, suit or proceeding and the proposed response of the
Guarantor thereto;

               (c) furnish to the Beneficiaries, as soon as possible and in any
event within three days after the Guarantor obtains Actual Knowledge of default
by the Guarantor of any of its material obligations under this Guaranty, a
statement of an authorized officer of the Guarantor setting forth details of
such default and the action which the Guarantor has taken and proposes to take
with respect thereto. Notwithstanding the foregoing provision in this clause
(c), the Guarantor shall, within 120 days after the close of each fiscal year of
the Guarantor in which Certificates are outstanding hereunder, file with the
Owner Participant, and if the Certificates are outstanding during any part of
such fiscal year, the Indenture Trustee and the Pass Through Trustee, an
Officer's Certificate, provided that one Officer executing the same shall be the
principal executive officer, the principal financial officer or the principal
accounting officer of the Guarantor, covering the period from the date hereof to
the end of the fiscal year in which this Guaranty was executed and delivered by
the Guarantor, in the case of the first such certificate, and covering the
preceding fiscal year in the case of each subsequent certificate, and stating
whether or not, to the Actual Knowledge of each



                                       10
   13

such executing Officer, the Guarantor has complied with and performed and
fulfilled all covenants on its part contained in this Guaranty and is not in
Default in the performance or observance of any of the terms or provisions
contained in this Guaranty, and, if any such signer has obtained Actual
Knowledge of any Default by the Guarantor in the performance, observance or
fulfillment of any such covenant, terms or provision specifying each such
Default and the nature thereof; and

               (d) promptly furnish to the Owner Participant, the Owner Lessor,
the Indenture Trustee or the Pass Through Trustee such other information as the
Owner Lessor, Owner Participant, the Indenture Trustee and the Pass Through
Trustee may from time to time reasonably request with respect to the Guarantor.

        So long as the Indenture Trustee is also serving as the Pass Through
Trustee, delivery to the Indenture Trustee shall satisfy the Guarantor's
obligation to furnish information to the Pass Through Trustee under this Section
3.2

               Section 3.3. The Guarantor covenants and agrees that it will not
transfer or assign or cause to be transferred or assigned the Ownership Interest
in the Rumford Lessee to any other Person, without the prior written consent of
the Owner Lessor, the Owner Participant and, so long as the Lien of the
Collateral Trust Indenture has not been terminated or discharged, the Indenture
Trustee and the Pass Through Trustee (it being agreed and understood that a
consolidation with or merger of the Guarantor into, or a sale by the Guarantor
of all or substantially all of its assets to, another Person in accordance with
Section 3.6 hereof shall not be deemed to be a transfer or assignment of the
Ownership Interest in the Rumford Lessee for the purposes of this Section),
except as permitted in this Section 3.3 or in Section 8.4 hereof.
Notwithstanding the foregoing, and subject to Section 8.4 below, so long as this
Guaranty remains in full force and effect, the Guarantor may transfer a portion
of the Ownership Interest in the Rumford Lessee (provided that following such
transfer the Guarantor shall continue to own at least a majority of the
Ownership Interest in the Rumford Lessee, as well as at least a majority of the
Ownership Interest in the Rumford Lessee) without the consent of the Owner
Lessor, the Owner Participant, the Indenture Trustee, the Pass Through Trustee
or any other Transaction Party if the following conditions have been satisfied:

               (i) the Owner Lessor, the Owner Participant and, so long as the
        Lien of the Collateral Trust Indenture shall not have been terminated or
        discharged, the Indenture Trustee and the Pass Through Trustee shall
        have received an Opinion of Counsel to the effect that all regulatory
        approvals required in connection with such transfer have been obtained;

               (ii) all the obligations of the Rumford Lessee under the Rumford
        Operative Documents shall remain in full force and effect, the Guarantor
        shall reaffirm in writing all of its obligations hereunder in a manner
        reasonably satisfactory to the Owner Participant, such obligations of
        the Guarantor shall remain in full force and effect;



                                       11
   14

               (iii) no Significant Lease Default or Lease Event of Default
        shall have occurred and be continuing at the time of or immediately
        following such transfer;

               (iv) the transfer shall not subject the Rumford Lessee, the
        Rumford Lessee, the Owner Participant, the Owner Lessor, the Indenture
        Trustee, the Pass Through Trustee or any Certificateholder to regulation
        under PUHCA or state laws and regulations regarding the rate and
        financial or organizational regulation of electric utilities in the
        affected party's reasonable opinion, nor result in a Regulatory Event of
        Loss; and

               (v) the Rumford Lessee shall have paid, at no after-tax cost to
        such parties, all reasonable and documented out-of-pocket expenses
        (including reasonable attorneys' fees and expenses) of the Owner Lessor,
        the Owner Participant, the Indenture Trustee, the Lease Indenture
        Company and the Pass Through Trustee in connection with such assignment.

               Section 3.4. Subject to Section 4, the Guarantor shall not, and
shall not permit any Restricted Subsidiary to, enter into any Sale/Leaseback
Transaction unless (i) the Guarantor or such Restricted Subsidiary would be
entitled to create a Lien on such property securing Indebtedness in an amount
equal to the Attributable Debt with respect to such transaction without equally
and ratably securing the Obligations (Rumford) pursuant to Section 3.5 or (ii)
the net proceeds of such sale are at least equal to the fair value (as
determined by the Board of Directors) of such property or asset and the
Guarantor or such Restricted Subsidiary shall apply or cause to be applied an
amount in cash equal to the net proceeds of such sale to the retirement, within
180 days of the effective date of any such arrangement, of Indebtedness of the
Guarantor or any Restricted Subsidiary; provided, however, that in addition to
the transactions permitted pursuant to the foregoing clauses (i) and (ii), the
Guarantor or any Restricted Subsidiary may enter into a Sale/Leaseback
Transaction as long as the sum of (x) the Attributable Debt with respect to such
Sale/Leaseback Transaction and all other Sale/Leaseback Transactions entered
into pursuant to this proviso plus (y) the amount of outstanding Indebtedness
secured by Liens Incurred pursuant to the final proviso to Section 3.5 does not
exceed 15% of Consolidated Net Tangible Assets as determined based on the
consolidated balance sheet of the Guarantor as of the end of the most recent
fiscal quarter for which financial statements are available; and provided,
further, that a Restricted Subsidiary may enter into a Sale/Leaseback
Transaction with respect to property or assets owned by such Restricted
Subsidiary, the proceeds of which are used to explore, drill, develop,
construct, purchase, repair, improve or add to property or assets of any
Restricted Subsidiary, or to repay (within 365 days of the commencement of full
commercial operation of any such property) Indebtedness Incurred to explore,
drill, develop, construct, purchase, repair, improve or add to property or
assets of any Restricted Subsidiary.

               Section 3.5. Subject to Section 4, the Guarantor shall not, and
shall not permit any Restricted Subsidiary to, directly or indirectly, incur any
Lien on any of its properties or assets (including Capital Stock), whether owned
at the date hereof or thereafter acquired, in each case to secure Indebtedness
of the Guarantor or any



                                       12
   15

Restricted Subsidiary, other than (a)(1) Liens incurred by the Guarantor or any
Restricted Subsidiary securing Indebtedness Incurred by the Guarantor or such
Restricted Subsidiary, as the case may be, to finance the exploration, drilling,
development, construction or purchase of or by, or repairs, improvements or
additions to, property or assets of the Guarantor or such Restricted Subsidiary,
as the case may be, which Liens may include Liens on the Capital Stock of such
Restricted Subsidiary or (2) Liens incurred by any Restricted Subsidiary that
does not own, directly or indirectly, at the time of such original incurrence of
such Lien under this clause (2) any operating properties or assets, securing
Indebtedness Incurred to finance the exploration, drilling, development,
construction or purchase of or by, or repairs, improvements or additions to,
property or assets of any Restricted Subsidiary that does not, directly or
indirectly, own any operating properties or assets at the time of such original
incurrence of such Lien, which Liens may include Liens on the Capital Stock of
one or more Restricted Subsidiaries that do not, directly or indirectly, own any
operating properties or assets at the time of such original incurrence of such
Lien, provided, however, that the Indebtedness secured by any such Lien may not
be issued more than 365 days after the later of the exploration, drilling,
development, completion of construction, purchase, repair, improvement, addition
or commencement of full commercial operation of the property or assets being so
financed; (b) Liens existing on the date hereof (other than Liens relating to
Indebtedness or other obligations being repaid or Liens that are otherwise
extinguished with the proceeds of the offering of the Certificates); (c) Liens
on property, assets or shares of stock of a Person at the time such Person
becomes a Subsidiary; provided, however, that any such Lien may not extend to
any other property or assets owned by the Guarantor or any Restricted
Subsidiary; (d) Liens on property or assets at the time the Guarantor or a
Subsidiary acquires the property or asset, including any acquisition by means of
a merger or consolidation with or into the Guarantor or a Subsidiary; provided,
however, that such Liens are not incurred in connection with, or in
contemplation of, such merger or consolidation; and provided, further, that the
Lien may not extend to any other property or asset owned by the Guarantor or any
Restricted Subsidiary; (e) Liens securing Indebtedness or other obligations of a
Subsidiary owing to the Guarantor or a Restricted Subsidiary or of the Guarantor
owing to a Subsidiary; (f) Liens incurred on assets that are the subject of a
Capitalized Lease Obligation to which the Guarantor or a Subsidiary is a party,
which shall include, Liens on the stock or other ownership interest in one or
more Restricted Subsidiaries leasing such assets; (g) Liens to secure any
refinancing, refunding, extension, renewal or replacement (or successive
refinancings, refundings, extensions, renewals or replacements) as a whole, or
in part, of any Indebtedness secured by any Lien referred to in the foregoing
clauses (a), (b), (c), (d) and (f), provided, however, that (x) such new Lien
shall be limited to all or part of the same property or assets that secured the
original Lien (plus repairs, improvements or additions to such property or
assets and Liens on the stock or other ownership interest in one or more
Restricted Subsidiaries beneficially owning such property or assets) and (y) the
amount of the Indebtedness secured by such Lien at such time (or, if the amount
that may be realized in respect of such Lien is limited, by contract or
otherwise, such limited lesser amount) is not increased (other than by an amount
necessary to pay fees and expenses, including premiums, related to the
refinancing, refunding, extension, renewal or replacement of such Indebtedness);
and (h) Liens by which the Obligations (Rumford)



                                       13
   16

are secured equally and ratably with other Indebtedness pursuant to this Section
3.5; in any such case without effectively providing that the Obligations
(Rumford) shall be secured equally and ratably with (or prior to) the
obligations so secured for so long as such obligations are so secured; provided,
however, that the Guarantor or a Restricted Subsidiary may Incur other Liens to
secure outstanding Indebtedness as long as the sum of (x) the lesser of (A) the
amount of outstanding Indebtedness secured by Liens Incurred pursuant to this
proviso (or, if the amount that may be realized in respect of such Lien is
limited, by contract or otherwise, such limited lesser amount) and (B) the fair
value (as determined by the Board of Directors) of the property securing such
item of Indebtedness, plus (y) the Attributable Debt with respect to all
Sale/Leaseback Transactions entered into pursuant to the first proviso to
Section 3.4 does not exceed 15% of Consolidated Net Tangible Assets as
determined based on the Consolidated balance sheet of the Guarantor as of the
end of the most recent fiscal quarter for which financial statements are
available.

               Section 3.6. (a) The Guarantor covenants and agrees that it shall
not consolidate or merge with or into any other Person, or sell, assign, convey,
lease, transfer or otherwise dispose of, all or substantially all of its
properties or assets to any Person or Persons in one or a series of
transactions, unless immediately after giving effect to such transaction,

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

               (ii) either (A) the Guarantor shall be the continuing Person, or
        (B) the Person (if other than the Guarantor) formed by such
        consolidation or into which the Guarantor is merged or to which the
        properties and assets of the Guarantor are sold, assigned, conveyed,
        transferred, disposed of or leased as aforesaid shall be an entity
        organized and existing under the laws of the United States or any State
        thereof or the District of Columbia and shall execute and deliver to the
        Owner Participant, the Owner Lessor and, so long as the Lien of the
        Collateral Trust Indenture shall not have been terminated or discharged,
        the Indenture Trustee and the Pass Through Trustee, a Guarantor's
        Assignment and Assumption Agreement; and

               (iii) each of the Owner Participant, the Owner Lessor and, so
        long as the Lien of the Collateral Trust Indenture shall not have been
        terminated or discharged, the Indenture Trustee and the Pass Through
        Trustee shall have received an Officer's Certificate of the Guarantor,
        the surviving entity or the transferee, as the case may be, in form and
        substance reasonably satisfactory to each of such parties, stating that
        the proposed merger, consolidation, assignment, conveyance, transfer,
        disposition, lease or sale, and the Guarantor Assignment and Assumption
        Agreement complies with the terms of this Section 3(a) and, as to legal
        matters, an Opinion of Counsel; and

               (iv) In addition to the conditions set forth in clauses (i)
        through (iii) above, the Guarantor, subject to Section 4, will not
        consummate any such



                                       14
   17

        consolidation, merger or sale of all or substantially all of its
        properties or assets unless the long-term unsecured debt of the
        resulting, surviving or succeeding entity shall have a credit rating
        assigned by the Rating Agencies that is not less than the lower of (x)
        the credit rating of the long-term unsecured debt of the Guarantor
        assigned by the Rating Agencies immediately prior to such transaction
        and (y) a credit rating of the long-term unsecured debt of the
        resulting, surviving or succeeding entity assigned by the Rating
        Agencies that is Investment Grade; provided however, the foregoing
        credit rating condition set forth in this paragraph may be waived by the
        Owner Participant in its sole discretion, and provided further, that if
        such credit rating condition is not otherwise satisfied, or waived by
        the Owner Participant, the Guarantor, the surviving entity or the
        transferee, as the case may be, may provide (and maintain in accordance
        with the provisions of Section 5.46(vi)(b) through (k) of the
        Participation Agreement (with appropriate conforming changes)) in the
        alternative, either (A) a Qualifying Letter of Credit from a Qualifying
        Letter of Credit Bank with at least an A rating from S&P and A2 rating
        from Moody's covering the Equity Portion of Termination Value from time
        to time throughout the Lease Term, or (B) if the long-term unsecured
        debt of the surviving entity or the transferee, as the case may be, has
        a credit rating assigned by the Rating Agencies at least equal to that
        of Calpine at Closing, a Qualifying Letter of Credit from a Qualifying
        Letter of Credit Bank with at least an A rating from S&P and A2 from
        Moody's covering fifty percent (50%) of the Equity Portion of
        Termination Value from time to time throughout the Lease Term or (C)
        alternative or additional credit support arrangements which result in
        the satisfaction of the rating condition in either clause (x) or clause
        (y) above, provided that such arrangements contemplated in this
        sub-clause (C) are satisfactory to the Owner Participant and result in
        the satisfaction of such rating condition.

               (b) Upon the consummation of such transaction described in
Section 3.6(a), the resulting, surviving or succeeding entity, if other than the
Guarantor, shall succeed to, and be substituted for, and may exercise every
right and power and shall perform every obligation of, the Guarantor under this
Guaranty and each other Calpine Document, and from and after the effective date
and time of the consummation of such transfer, the Guarantor shall be released
from all obligations accruing hereunder other than those accruing prior to such
effective date and time.

               Section 3.7. The Guarantor shall, together with each payment it
makes hereunder, provide a written notice to each Beneficiary or Beneficiaries
which are the intended recipients of such payment of the amount payable to each
such Beneficiary and the Rumford Operative Document(s) with respect to which
such payment is being made.

SECTION 4. BENEFICIARIES; TERMINATION OF CERTAIN COVENANTS

               The Owner Participant, the Owner Lessor, the Trust Company (but
only to the extent indemnified under the Participation Agreement) and, so long
as the Lien of the Collateral Trust Indenture has not been terminated or
discharged, the Indenture Trustee and the Lease Indenture Company, and (but only
to the extent expressly referred to



                                       15
   18

herein, and with respect to Section 3.2(a) hereof and with respect to the
obligations of the Rumford Lessee under the Participation Agreement) the Pass
Through Trustee (for the benefit of the Certificateholders) and the Pass Through
Company, in each case, together with their respective permitted successors and
assigns (and with respect to clause (ii) below, the other related Persons
referred to therein), are each beneficiaries of this Guaranty (each a
"Beneficiary" or, together, the "Beneficiaries"); provided that, notwithstanding
the foregoing or any other provision of this Guaranty, (i) the Owner Participant
shall be the sole and exclusive beneficiary of, and shall have the sole right to
enforce, (A) clause (iv) of Section 3.6(a) hereof, (B) clause (4) of Section
2.1(a) hereof to the extent relating to the Rumford Lessee's indemnity
obligation under the Tax Indemnity Agreement, (ii) to the extent that the
Rumford Lessee is obligated to indemnify a particular Beneficiary (or any
Affiliate, agent director, officer, or employee thereof) in accordance with
Section 9 of the Participation Agreement, then such Beneficiary (or such
Affiliate, agent, director, officer or employee) shall be the sole and exclusive
beneficiary of, and shall have the sole right to enforce, the Guarantor's
guaranty of, and agreement with respect to, such indemnification obligation
hereunder, (iii) the Owner Lessor shall be the sole and exclusive beneficiary
of, and shall have the sole right to enforce clause (B) of Section 2.1(c) hereof
and the fourth sentence of Section 2.1(b) hereof, and (iv) the Indenture
Trustee, the Lease Indenture Company, the Pass Through Trustee and the Pass
Through Company shall be the sole and exclusive beneficiaries of the provisions
of Section 3.4 and Section 3.5 hereof; provided however, with respect to this
clause (iii), once the Certificates shall have been paid in full, the covenants
set forth in Section 3.4 and Section 3.5 hereof shall, subject to the
immediately following sentence, immediately and without any further action
terminate and be of no further force or effect. Any amendment, waiver or
modification of or supplement to Section 3.4 or Section 3.5 which is consented
to by the Indenture Trustee shall be binding upon the Owner Lessor and the Owner
Participant. Notwithstanding the foregoing or anything herein or in any of the
Rumford Operative Documents to the contrary, if the Owner Lessor shall have
issued additional Lease Debt at the request of the Rumford Lessee in accordance
with Section 11 of the Participation Agreement prior to, simultaneously with, or
after payment in full of the Certificates and such new Lease Debt is outstanding
on or after the date the Certificates are paid in full, the covenants set forth
in Section 3.4 and Section 3.5 shall, to the extent required by the terms of
such new Lease Debt, remain in effect or thereafter become effective if not then
in effect, but shall be for the sole and exclusive benefit of, and enforceable
solely by, the holder of such new Lease Debt. Upon repayment of such new Lease
Debt, or compliance with the terms thereof, the covenants set forth in Section
3.4 and Section 3.5 shall immediately and without further action terminate and
be of no further force and effect. Notwithstanding any of the preceding
provisions, a breach of Sections 3.4 or 3.5 under this Guaranty at such time as
such breach shall have become an "Event of Default" under Section 7.1 shall
constitute a Lease Event of Default under the circumstances provided in, and to
the extent set forth in, the Rumford Facility Lease.

SECTION 5. BENEFICIARIES' RIGHTS

               Each Beneficiary may at any time and from time to time without
the consent of, or notice to the Guarantor, without incurring responsibility to
the Guarantor



                                       16

and without impairing or releasing the obligations of the Guarantor hereunder,
upon or without any terms or conditions and in whole or in part:

               (a) change the manner, place or terms of payment of, and/or
change or extend the time of payment of, renew or alter, any of the Obligations
(Rumford) due to it, any security therefor, or any liability incurred directly
or indirectly in respect thereof, and, subject to clause (d) below, the guaranty
and agreement herein made shall apply to the Obligations (Rumford) due to it as
so changed, extended, renewed or altered;

               (b) sell, exchange, release, surrender, realize upon or otherwise
deal with in any manner and in any order any property by whomsoever at any time
pledged or mortgaged to secure, or howsoever securing, the Obligations (Rumford)
or any liabilities (including any of those hereunder) incurred directly or
indirectly in respect thereof or hereof due to it, and/or any offset
thereagainst due to it;

               (c) exercise or refrain from exercising any rights against the
Rumford Lessee or others or otherwise act or refrain from acting;

               (d) settle or compromise any of the Obligations (Rumford) due to
it, any security therefor or any liability (including any of those hereunder)
incurred directly or indirectly in respect thereof or hereof, and may
subordinate the payment of all or any part thereof to the payment of any
liability (whether due or not) of the Rumford Lessee to its creditors other than
the Guarantor; provided that any settlement or compromise with respect to, or
other reduction (by operation of law or negotiation) of, any of the Obligations
(Rumford) (or amounts underlying such Obligations (Rumford)) due to it (whether
occurring before or after the occurrence of a Lease Event of Default) shall not
alter the amount of the original Obligations (Rumford) due to it guaranteed
hereby and the Guarantor acknowledges and agrees that its obligations hereunder
shall be for the full amount of the Obligations (Rumford) due to it without
giving effect to any such settlement, compromise or other reduction;

               (e) apply any sums by whomsoever paid or howsoever realized to
any liability or liabilities of the Rumford Lessee to such Beneficiary
regardless of what liabilities or liabilities of the Rumford Lessee remain
unpaid;

               (f) consent to or waive any breach of, or any act, omission or
default under, the Participation Agreement or the Rumford Facility Lease, or
otherwise amend, modify or supplement the Participation Agreement or the Rumford
Facility Lease or any of such other instruments or agreements; and/or

               (g) act or fail to act in any manner referred to in this Guaranty
which may deprive the Guarantor of its right to subrogation against the Rumford
Lessee to recover full indemnity for any payments made pursuant to this
Guaranty.

Anything herein to the contrary notwithstanding, any exercise of rights or
remedies by any Beneficiary hereunder or under any other Rumford Operative
Document, or the failure or any Beneficiary to exercise any rights or remedies
hereunder in accordance with the provisions hereof or under any other Rumford
Operative Document, shall not in



                                       17
   20

any way adversely affect the ability of any other Beneficiary to exercise its
rights or remedies hereunder.

SECTION 6. SURVIVAL OF GUARANTY AND PAYMENT AGREEMENT (RUMFORD)

               Notwithstanding anything to the contrary herein, this Guaranty
shall continue to be effective or be reinstated, as the case may be, if at any
time any of the amounts paid to any of the Beneficiaries, in whole or in part,
is required to be repaid upon the insolvency, bankruptcy, dissolution,
liquidation, or reorganization of the Guarantor or the Rumford Lessee or any
other Person, or as a result of the appointment of a custodian, interviewer,
receiver, trustee, or other officer with similar powers with respect to the
Guarantor or the Rumford Lessee or any other Person or any substantial part of
the property of the Guarantor or the Rumford Lessee or such other Person, all as
if such payments had not been made.

SECTION 7. DEFAULTS; REMEDIES; SUBROGATION

               Section 7.1. Defaults. The following events shall constitute an
"Event of Default" hereunder (whether any such event shall be voluntary or
involuntary or come about or be effected by operation of law or pursuant to or
in compliance with any judgment, decree or order of any court or any order, rule
or regulation of any Governmental Entity):

               (a) the Guarantor or the Rumford Lessee under the Rumford
Facility Lease shall fail to make any payment with respect to Periodic Rent or
Termination Value (including the Equity Portion of Termination Value or Debt
Portion of Termination Value) when due and payable under such Rumford Facility
Lease or this Guaranty within five (5) days after the same shall become due
thereunder; or

               (b) the Guarantor or the Rumford Lessee shall fail to make any
other amount payable under any Rumford Operative Document after the same shall
become due thereunder and such failure shall have continued from a period of ten
(10) Business Days after receipt by the Rumford Lessee and the Guarantor of
written notice of such failure by the Rumford Lessee and/or the Guarantor, as
applicable;

               (c) The Guarantor shall fail to comply with its covenants set
forth in Section 3.3 (transfer of Lessee ownership), 3.6 (Guarantor merger) or
8.4 (assignment of Guaranty) of this Guaranty.

               (d) the Guarantor shall fail to perform or observe any covenant,
obligation or agreement to be performed or observed by it under any Calpine
Document (other than any covenant, obligation or agreement referred to in
clauses (a) or (b) of this Section 7.1) in any material respect, which shall
continue unremedied for (1) with respect to the Guarantor's guaranty of, and
agreement with respect to, any nonmonetary obligation, covenant or agreement of
the Rumford Lessee under any of the Rumford Operative Documents, 30 days after
receipt by the Guarantor of written notice thereof from the Owner Participant,
the Owner Lessor, the Indenture Trustee or the Pass Through



                                       18
   21

Trustee; provided, however, if such condition cannot be remedied within such
30-day period, then the period within which to remedy such condition shall be
extended up to an additional 180 days, so long as the Guarantor diligently
pursues such remedy and such condition is reasonably capable of being remedied
within such additional 180-day period, and (2) with respect to any other
obligation, covenant or agreement hereunder, 30 days after receipt by the
Guarantor of written notice thereof;

               (e) there shall have occurred either (i) a default by the
Guarantor or any Restricted Subsidiary under any instrument or instruments under
which there is or may be secured or evidenced any Indebtedness of the Guarantor
or any Restricted Subsidiary of the Guarantor (other than the Obligations
(Rumford)) having an outstanding principal amount of $50,000,000 (or its foreign
currency equivalent) or more individually or in the aggregate that has caused
the holders thereof to declare such Indebtedness to be due and payable prior to
its Stated Maturity, unless such declaration has been rescinded within 30 days
or (ii) a default by the Guarantor or any Restricted Subsidiary in the payment
when due of any portion of the principal under any such instrument or
instruments, and such unpaid portion exceeds $50,000,000 (or its foreign
currency equivalent) individually or in the aggregate and is not paid, or such
default is not cured or waived, within any grace period applicable thereto,
unless such Indebtedness is discharged within 30 days of the Guarantor or a
Restricted Subsidiary becoming aware of such default;

               (f) the Guarantor or any Significant Subsidiary pursuant to or
within the meaning of any Bankruptcy Law:

                      (i)    commences a voluntary case;

                      (ii)   consents to the entry of an order for relief
                             against it in an involuntary case;

                      (iii)  consents to the appointment of a Custodian of it or
                             for all or substantially all of its property;

                      (iv)   makes a general assignment for the benefit of its
                             creditors; or

                      (v)    admits in writing its inability to generally pay
                             its debts as such debts become due;

               or takes any comparable action under any foreign laws relating to
insolvency;

               (g) an involuntary case or other proceeding shall be commenced
against the Guarantor or any Significant Subsidiary seeking (i) liquidation,
reorganization or other relief with respect to it or its debts under Title 11 of
the Bankruptcy Code or any bankruptcy, insolvency or other similar law now or
hereafter in effect, or (ii) the appointment of a trustee, receiver, liquidator,
custodian or other similar official with respect to it or any substantial part
of its property or (iii) the winding-up or liquidation of



                                       19
   22

the Guarantor or such Significant Subsidiary; and such involuntary case or other
proceeding shall remain undismissed and unstayed for a period of 60 days;

               (h) any representation or warranty made by the Guarantor herein
shall prove to have been incorrect in any material respect when made or
misleading in any material respect when made because of the omission to state a
material fact and such incorrect or misleading representation is and continues
to be material and unremedied for a period of 30 days after receipt by the
Guarantor of written notice thereof; provided, however, that if such condition
cannot be remedied within such 30-day period, then the period within which to
remedy such condition shall be extended up to an additional 60 days, so long as
the Guarantor diligently pursues such remedy and such condition is reasonably
capable of being remedied within such additional 60-day period.

        The grace periods set forth in Section 7.1(a) and (b) above shall not
affect in any way the right hereunder of any Beneficiary entitled to a payment
of any amount payable to it, or performance of any obligation, by the Rumford
Lessee under any Rumford Operative Document to demand prompt payment thereof, or
performance thereof, by the Guarantor immediately upon any failure of the
Rumford Lessee to pay or perform the same when it has become due (and, for the
avoidance of doubt, without regard to the existence of any cure or grace period
before such failure by the Rumford Lessee becomes a Lease Event of Default);
provided, however, notwithstanding the foregoing, no Lease Event of Default
under Section 16(m) and no remedies under the Rumford Facility Lease may be
exercised until a Calpine Guaranty Event of Default has occurred and is
continuing.

               Section 7.2. Remedies. Subject to the last paragraph of Section
7.1, each Beneficiary shall be entitled to (a) all rights and remedies to which
it may be entitled hereunder or at law, in equity or by statute and may proceed
by appropriate court action to enforce the terms hereof and to recover damages
for the breach hereof. Each and every remedy of the Beneficiaries shall, to the
extent permitted by law, be cumulative and shall be in addition to any other
remedy now or hereafter existing at law or in equity. At the option of each
Beneficiary and upon notice to the Guarantor, the Guarantor may be joined in any
action or proceeding commenced by such Beneficiary against the Rumford Lessee in
respect of any Obligations (Rumford) and recovery may be had against the
Guarantor in such action or proceeding or in any independent action or
proceeding against the Guarantor, without any requirement such Beneficiary first
assert, prosecute or exhaust any remedy or claim against the Rumford Lessee.
Notwithstanding any of the foregoing, if an Event of Default specified in clause
(e) or (f) of Section 7.1 with respect to the Guarantor occurs, all monetary
Obligations (Rumford) shall ipso facto become and be immediately due and payable
without any declaration or other act on the part of the Owner Participant, the
Owner Lessor, the Indenture Trustee or the Pass Through Trustee.

               Section 7.3. Subrogation. The Guarantor will not exercise any
rights that it may acquire by way of subrogation under this Guaranty, by any
payment made hereunder or thereunder or otherwise, until all of the Obligations
(Rumford) and all other obligations of the Rumford Lessee and the Guarantor
owing to any of the Beneficiaries (or any other party) under the Rumford
Operative Documents shall have been paid in full.



                                       20
   23

If any amount shall be paid to the Guarantor on account of such subrogation
rights at any time when all of the Obligations (Rumford) and such other
obligations shall not have been paid in full, such amount shall be held in trust
for the benefit of the Beneficiary to whom such Obligation (Rumford) or other
obligation is payable and shall forthwith be paid to such Beneficiary to be
credited and applied to such Obligation (Rumford) or other obligation, whether
matured or unmatured, in accordance with the terms of the Rumford Operative
Document under which such Obligation (Rumford) or other obligation arose. If (i)
the Guarantor shall make payment to any Beneficiary of all or any part of the
Obligations (Rumford) or other obligations and (ii) all the Obligations
(Rumford) and such other obligations shall be paid and performed in full, such
Beneficiary will, at the Guarantor's request and expense, execute and deliver to
the Guarantor appropriate documents, without recourse, subject to Section 6
hereof, necessary to evidence the transfer by subrogation to the Guarantor of an
interest in the Obligations (Rumford) and such other obligations resulting from
such payment by the Guarantor.

               Section 7.4. Waiver of Demands, Notices, Etc.

               (a) Without limiting the last sentence of Section 7.1, the
Guarantor hereby unconditionally waives (i) notice of any of the matters
referred to in the second sentence of Section 2.3 hereof; (ii) all notices which
may be required by statute, rule of law or otherwise, now or hereafter in
effect, to preserve any rights against the Guarantor hereunder, including,
without limitation, any demand, proof or notice of non-payment of any Obligation
(Rumford); (iii) any right to the enforcement, assertion or exercise of any
right, remedy, power or privilege under or in respect of the Rumford Facility
Lease (or under or in respect of any other agreement including any Rumford
Operative Document); (iv) notice of acceptance of this Guaranty, demand,
protest, presentment, notice of default and any requirement of diligence; (v)
any requirement to exhaust any remedies or to mitigate any damages resulting
from default by the Rumford Lessee or any Person under the Rumford Facility
Lease (or under any other agreement including any Rumford Operative Document);
and (vi) any other circumstance whatsoever which might otherwise constitute a
legal or equitable discharge, release or defense of a guarantor or surety, or
which might otherwise limit recourse against the Guarantor, other than
satisfaction in full of the Obligations (Rumford).

               (b) This Guaranty is a continuing one and all of the Obligations
(Rumford) shall be conclusively presumed to have been created in reliance
hereon. No failure or delay on the part of any Beneficiary in exercising any
right, power or privilege hereunder and no course of dealing among the
Guarantor, any Beneficiary or the Rumford Lessee shall operate as a waiver
thereof, nor shall any single or partial exercise of any right, power or
privilege hereunder preclude any other or further exercise thereof or the
exercise of any other right, power or privilege. The rights, powers and remedies
herein expressly provided are cumulative and not exclusive of any rights, powers
or remedies which the Beneficiary would otherwise have. No notice to or demand
on the Guarantor in any case shall entitle the Guarantor to any other further
notice or demand in similar or other circumstances or constitute a waiver of the
rights of any Beneficiary to any other or further action in any circumstances
without notice or demand.



                                       21
   24

               (c) If a claim is ever made upon any Beneficiary for repayment or
recovery of any amount or amounts received in payment or on account of any of
the Obligations (Rumford) and any of the Beneficiaries repays all or part of
said amount by reason of (a) any judgment, decree or order of any court or
administrative body having jurisdiction over such Beneficiary or any of its
property or (b) any settlement or compromise of any such claim effected by such
Beneficiary with any such claimant (including the Rumford Lessee), then and in
such event the Guarantor agrees that any such judgment, decree, order,
settlement or compromise shall be binding upon it, notwithstanding any
revocation hereof or the cancellation of the Rumford Facility Lease or other
instrument evidencing any liability of the Rumford Lessee, and the Guarantor
shall be and remain liable to the aforesaid Beneficiaries hereunder for the
amount so repaid by or recovered from such Beneficiary to the same extent as if
such amount had never originally been received by any such Beneficiary.

               Section 7.5. Costs and Expenses. The Guarantor agrees to pay on
an After-Tax Basis any and all reasonable costs and expenses (including
reasonable legal fees) incurred by any Beneficiary in enforcing its rights under
this Guaranty.

               Section 7.6. Survival of Remedies and Subrogation Rights. The
provisions of this Section 7 shall survive the term of this Guaranty and the
payment in full of the Obligations (Rumford) and the termination of the Rumford
Operative Documents.

SECTION 8. MISCELLANEOUS

               Section 8.1. Amendments and Waivers. No term, covenant, agreement

waived (either generally or in a particular instance, retroactively or
prospectively) except by an instrument or instruments in writing executed by the
Guarantor and consented to by the Beneficiaries.

        this Guaranty shall be deemed to be satisfactory to the Owner
        Participant); and

shall have expired, prevent the operation of such statute of limitations.

               Section 8.12. Consent to Jurisdiction; Waiver of Trail by Jury;

               (a) The Guarantor (i) hereby irrevocably submits to the

Avenue, 5th Floor, New York, NY 10001 as its authorized agent to receive for and
on its behalf service of any summons, complaint or other legal process in any
such action, suit or



                                       25

proceeding in the State of New York for so long as any obligation of the
Guarantor shall remain outstanding hereunder or under any of the other Rumford
Operative Documents. The Guarantor shall grant an irrevocable power of attorney
to National Registered Agent, Inc. in respect of such appointment and shall
maintain such power of attorney in full force and effect for so long as any
obligation of the Guarantor shall remain outstanding hereunder or under any of
the Rumford Operative Documents.

               Section 8.13. Agreement for Benefit of Parties Hereto. Nothing in
this Guaranty, express or implied, is intended or shall be construed to confer
upon, or to give to, any person other than the parties hereto and their
respective successors and assigns, any right, remedy or claim under or by reason
of this Guaranty or any covenant, condition or stipulation hereof; and the
covenants, stipulations and agreements contained in this Guaranty are and shall
be for the sole and exclusive benefit of the parties hereto and their respective
successors and assigns. The Guarantor acknowledges that certain of the rights of
the Owner Lessor hereunder have been or shall be assigned to and may be enforced
by the Indenture Trustee pursuant to the terms of the Collateral Trust Indenture
(excluding, among other things, rights to Excepted Payments), the Guarantor
hereby consents to such assignment and the Guarantor agrees to render
performance of such assigned obligations directly to the Indenture Trustee (as
assignee of the Owner Lessor). The Guarantor agrees to make all payments which
have been so assigned owing to the Owner Lessor under this Guaranty directly to
the account of the Indenture Trustee to be specified to the Guarantor in
writing, or to such other account specified in writing from time to time by the
Indenture Trustee.

               Section 8.14. Termination of Guaranty. Upon the full payment and
satisfaction of the Obligations (Rumford) and all of the Guarantor's obligations
hereunder, this Guaranty shall terminate and shall be of no further effect.
Nevertheless, this Guaranty shall continue to be effective or be reinstated, as
the case may be, if at any time, any payment, or any part thereof, of any of the
Obligations (Rumford) is rescinded or must otherwise be returned by any
Beneficiary upon the insolvency, bankruptcy, dissolution, liquidation or
reorganization of the Rumford Lessee or otherwise, all as though such payment
had not been made.

               Section 8.15. Additional Obligations (Rumford). Upon the
assumption by the Rumford Lessee of the Rumford Notes in connection with a
termination of the Rumford Lease, as permitted therein, the obligation of the
Rumford Lessee to pay principal of, and Make-Whole Amount if any, and interest
on the Rumford Notes, and amounts payable by it to the Indenture Trustee under
the Collateral Trust Indenture, shall thereupon become Obligations (Rumford) for
all purposes of this Guaranty, and the Guarantor shall therefor execute and
deliver to the Indenture Trustee such further guaranties, instruments and
documents as the Indenture Trustee may reasonably request in order to more fully
effectuate the Guarantor's unconditional guaranty of such additional Obligations
(Rumford).

               Section 8.16. Miscellaneous Provisions.

               (a) The provisions of Section 2 of this Guaranty are subject to
the provisions of Section 14.25 of the Participation Agreement.

               (b) When determining the amount of unpaid Equity Portion of
Termination Value to be paid by the Guarantor under Section 2 of this Guaranty,
the correct amount thereof shall be the applicable amount of Equity Portion of
Termination Value (as set forth in Exhibit A hereto) for the date of the demand
for payment or if the amount of Equity Portion of Termination Value is not set
forth for such date on Exhibit A hereto, the Equity Portion of Termination Value
shall be determined by interpolation between the values set forth on Exhibit A
for the date next preceding the date of the demand and the date next succeeding
the date of the demand on a straight-line basis assuming thirty day months.

               (c) The payment obligations of the Guarantor hereunder shall rank
pari passu with all other senior unsecured indebtedness of the Guarantor for
borrowed money.
