                                                                  EXECUTION COPY

                   MASTER OPERATION AND MAINTENANCE AGREEMENT

            THIS MASTER OPERATION AND MAINTENANCE AGREEMENT (the "Agreement"),
dated as of March 23, 2004 (the "Effective Date"), is entered into by and
between CALPINE GENERATING COMPANY, LLC, a Delaware limited liability company
("CGC"), the indirect wholly-owned subsidiaries of CGC listed on the signature
page hereof (each a "Facility Owner" or the "Company"), and CALPINE OPERATING
SERVICES COMPANY, INC., a Delaware corporation ("Operator").

                                    RECITALS

            A.    The Facility Owners own those fourteen gas-fired,
combined-cycle electric generation facilities described on Appendix B attached
hereto (each a "Facility").

            B. The Facility Owners are indirect, wholly-owned subsidiaries of
CGC.

            C.    Each Facility Owner desires to enter into this Agreement with
Operator pursuant to which Operator shall provide the Services with respect to
each Facility Owner's Facility, as more fully described herein.

            D.    Company and Operator have agreed to set forth their agreement
regarding the Services to be provided for each Facility in this single
Agreement, but the Agreement is intended to apply separately and independently
to each Facility, as described below.

            NOW, THEREFORE, in consideration of the mutual covenants and
agreements set forth herein and other valuable consideration, the parties hereto
agree as follows:

ARTICLE 1. DEFINITIONS

            1.1   Definitions. Capitalized terms used in this Agreement without
other definition shall have the meanings specified in Appendix A to this
Agreement, unless the context requires otherwise.

            1.2   General Terms. As used in this Agreement, the terms "herein,"
"herewith," and "hereof" are references to this Agreement, taken as a whole, the
term "includes" or "including" shall mean "including, without limitation," and
references to a "Section," "subsection," "clause," "Article," "Exhibit,"
"Appendix," or "Schedule" shall mean a Section, subsection, clause, Article,
Exhibit, Appendix or Schedule of this Agreement, as the case may be, unless in
any such case the context requires otherwise. All references to a given
agreement, instrument or other document shall be a reference to that agreement,
instrument or other document as modified, amended, supplemented and restated
through the date as of which such reference is made, and reference to a Law
includes any amendment or modification thereof. The singular shall include the
plural and the masculine shall

<PAGE>

include the feminine and neuter, and vice versa. Where the words "required,"
"approved," "satisfactory," "determined," "acceptable," "decision" or words of
like import are used in this Agreement, action by the Company is indicated
unless the context clearly indicates otherwise.

ARTICLE 2. EXHIBITS

            2.1   Appendix and Exhibits. This Agreement consists of this
document itself and the following Appendices which are specifically made a part
hereof by reference:

      APPENDIX A Definitions
      APPENDIX B Description of Facilities

            2.2   Conflicting Provisions. In the event of any conflict between
this document and any Appendix, schedule or exhibit hereto, the terms and
provisions of this document, as amended from time to time, shall control. In the
event of any conflict among the Appendices, the following order of priority
shall apply as among the Appendices: Appendix A and Appendix B. Subject to the
foregoing, the several instruments forming part of this Agreement are to be
taken as mutually explanatory of one another and in the case of ambiguities or
discrepancies within or between such parts the same shall be explained and
adjusted by the issuance of a written instruction by Company.

ARTICLE 3. APPOINTMENT; SERVICES

            3.1   Appointment.

            (a)   Subject to Sections 3.1(b) and 3.1(c) below, each Facility
Owner hereby appoints and retains Operator to carry out, throughout the Term,
the Services for each of the Facilities, including mobilizing in preparation for
carrying out the Services on the terms and conditions of this Agreement.
Operator hereby accepts such appointment and agrees to perform the Services in
accordance with the terms and conditions of this Agreement. This Agreement,
including all exhibits and attachments, shall constitute a separate contract
between each Facility Owner and Operator with respect to the Facility owned by
such Facility Owner, and "Facility Owner" shall be understood to mean the owner
of such Facility as indicated on Appendix B. Operator and each Facility Owner
agree that, upon the reasonable request of either party, they will execute
separate individual operation and maintenance agreements with respect to such
Facility Owner's Facility on the same terms and conditions (modified as
necessary to reflect the fact that only one Facility is covered) as are set
forth in this Agreement. The obligations and liabilities of Operator and the
applicable Facility Owner with respect to a given Facility are independent of
the obligations and liabilities of Operator and the other Facility Owners with
respect to the other Facilities, and events giving rise to a right to terminate
this Agreement with respect to one Facility shall not entitle Company or
Operator, as applicable, to terminate this Agreement with respect to any other
Facility.

            (b)   The Parties acknowledge that the Columbia Energy Center
Facility, the Pastoria Energy Center Facility and the Goldendale Energy Center
Facility have not yet achieved commercial operation and agree that Operator's
Services with respect to each of these Facilities will not commence until the
applicable Facility is ready to be started up and begin operation.

<PAGE>

            (c)   If CGC sells or otherwise transfers a Facility subject to this
Agreement, Company shall the right to terminate this Agreement with respect to
such Facility and the related Facility Owner (it being understood that a sale
in violation of agreements between the Company and the holders of the Secured
Obligations or a foreclosure on one or more of the Facilities by the holders of
the Secured Obligations does not constitute a sale by the Company for purposes
of this Section 3.1(c)). In such event, CGC, the applicable Facility Owner(s)
and Contractor shall amend this Agreement to add or delete such Facility and the
related Facility Owner, as applicable. If the Company sells or otherwise
transfers a Facility and elects to terminate this Agreement as provided above,
this Agreement shall not apply to such Facility and the related Facility Owner
from and after the effective date of such sale, and CGC, the applicable Facility
Owner and Operator will be released from all future liabilities, and will no
longer have any obligations, hereunder with respect to such Facility.

            3.2   Services. Subject to Sections 3.1(b) and 3.1(c), Operator
shall operate and maintain the Facilities in accordance with the standards
described in Section 4.1 below and perform, or cause to be performed, on behalf
of the applicable Facility Owner all customary and reasonable operating and
maintenance services provided by operators of power plants similar to the
Facilities, including the services described in this Section 3.2 with respect to
each Facility (the "Services"); provided, however, that the Services shall not
include any services provided or to be provided under the Administrative
Services Agreement. From and after the Effective Date, Operator shall:

            (a)   Advertise for, interview and hire qualified staff to operate
each Facility;

            (b)   Conduct orientation programs for new employees which describe
Operator's personnel policies, procedures and training programs;

            (c)   Train the staff;

            (d)   Prepare an Operating Plan, as described in Section 3.4;

            (e)   Develop a reasonable spare parts inventory lists and purchase
office equipment, initial tools, spare parts, and supplies to operate the plant;

            (f)   Operate and manage each Facility in accordance with the
Operating Plan and in compliance with all applicable Laws;

            (g)   Propose a budget for the approval of Company in accordance
with Section 8;

            (h)   Provide procurement services with respect to all materials
(except fuel), supplies, parts, equipment, vehicles, and other items and
inventory necessary for the operation and maintenance of each Facility;

            (i)   Prepare and maintain for the review of the Facility Owner
complete written operating instructions and maintenance procedures as required
(including a Maintenance Program, an Operating Program, a Safety Program and a
Water Treatment Program); identify facility improvements; plan changes; and
budget, schedule, and manage outage work;

<PAGE>

            (j)   Maintain an emergency response plan for each Facility, and
take such actions and implement such procedures as Operator deems necessary to
provide reasonable safety and security for each Facility;

            (k)   Perform, or cause to be performed by Subcontractors, all
ordinary maintenance (not including Major Maintenance) for the Facility in
accordance with the Operating Plan and the Maintenance Program;

            (l)   Prepare, in connection with the Operating Plan, an annual
schedule of anticipated fuel use, and advise the Facility Owner in a timely
manner as to changes in fuel requirements;

            (m)   Schedule, in coordination with the parties to the Power Sales
Contracts, power outages and maintenance shutdowns to minimize revenue loss;

            (n)   Collect data for reporting to permitting and licensing
agencies, including the Federal Energy Regulatory Commission, and prepare and
submit the required reports;

            (o)   Prepare a Hazardous Substances Plan for each Facility, update
such plan from time to time as appropriate, and observe the provisions of the
Hazardous Substance Plan applicable to such Facility;

            (p)   Maintain complete and accurate records of all activities
relating to each Facility, and provide monthly reports regarding the operation
and maintenance of each Facility to the Facility Owner;

            (q)   Enforce and represent Company in connection with its claims
under contractor's and manufacturer's warranties;

            (r)   Timely pay each Facility's vendors for the goods and services
they provide, unless Operator in good faith disputes any amounts due and reports
such dispute to the Facility Owner; and

            (s)   Provide such additional reports, certificates, invoices and
other information as Company may from time to time require.

            3.3   Emergencies. Notwithstanding any other provision of this
Agreement, if Operator believes in good faith that an Emergency exists at a
Facility and that changes or modifications in the Services for that Facility are
required to avoid or mitigate losses from such Emergency, Operator may make such
changes or modifications to the extent required by such Emergency. Operator
shall promptly notify Company of the Emergency, the remedial and preventive
measures taken, the costs incurred, and, if appropriate, proposals to modify
procedures or services in light of the circumstances resulting in the Emergency.

            3.4   Operating Plan. In furtherance of its general responsibilities
described elsewhere this Agreement, Operator shall have the following planning
responsibilities for each Facility:

<PAGE>

            (a)   Not less than sixty (60) Days prior to the respective
anticipated commercial operation dates of the Columbia Energy Center Facility,
the Pastoria Energy Center Facility and the Goldendale Energy Center Facility,
and within thirty (30) Days after the Effective Date with respect to the other
Facilities, and not less than sixty (60) Days prior to the end of each
subsequent Calendar Year, Operator shall prepare and submit for Company's
approval a detailed plan for the operation and maintenance (including both
routine and major maintenance) of each Facility, in each case for the following
Calendar Year. Unless otherwise agreed by Company and Operator, such plan shall
be divided into three principal categories: (i) routine operation and
maintenance, (ii) Major Maintenance and (iii) Capital Expenditures. The plan
shall include descriptions, rationales and procedures for both routine operation
or maintenance and for major maintenance, a description of projected results
from operations, including a schedule for meeting significant milestones, a
schedule of major maintenance outages for the upcoming Calendar Year, a
projection of heat rate, staffing plan and other organizational details,
including a description of the personnel required to achieve the results and
milestones, and such other matters as may be requested by Company. The Major
Maintenance and Capital Expenditures portions of such plan shall include
projections for scheduled inspections and overhauls and for Capital Expenditures
for each Facility over the next six years.

            (b)   Operator shall consult with Company as it may request
regarding the assumptions and projections underlying the Operator's proposed
plan for each Facility. Company shall, within thirty (30) Days following the
receipt of Operator's proposed plan for a Facility, either accept the proposed
plan or modify the proposed plan; provided, however, that no modification may be
made which impairs Operator's ability to deliver Services for such Facility in
accordance with the standards set out at Section 4.1.

            (c)   Upon approval of a proposed plan by Company or upon its
modification by Company as provided in Section 3.4(d), the plan as approved or
modified shall be deemed to be the "Operating Plan" for the applicable Facility
for purposes of this Agreement and shall be implemented and carried out by
Operator in accordance with the terms and conditions of this Agreement. Operator
shall continue to operate each Facility in accordance the most recently approved
Operating Plan for such Facility until such time as a revised plan has been
approved by Company.

            (d)   From time to time during any Calendar Year, Company may, upon
consultation with Operator and by notice to Operator given not less than thirty
(30) Days prior to the effective date thereof, propose to amend the then current
Operating Plan for a Facility. Such notice shall be deemed to be a Change Order
with respect to such Facility as provided in Section 7.

            3.5   Subcontracts. Operator may subcontract with qualified
Subcontractors, including Affiliates of Operator, for such routine or
non-routine, work as is necessary to perform scheduled or unscheduled
maintenance and repairs, annual inspections and equipment overhauls.
Subcontracting shall not relieve Operator of any of its duties hereunder.
Operator shall not enter into any subcontract for the day-to-day operation or
the routine daily maintenance of a Facility without Company's prior written
approval. All subcontracts between Operator and its Affiliates shall be on terms
and conditions that are no less favorable to Company than would be obtained from
unaffiliated third parties.

respect to all of the Facilities except the Columbia Energy Center Facility, the
Pastoria Energy Center Facility and the Goldendale Energy Center Facility
(Services with respect to such Facilities commencing as set forth in Section
3.1(b)) and continuing for the balance of the Term. Each Plant Manager, and each
successor Plant Manager, shall be named by Operator by written notice to
Company, but each such nomination shall be subject to approval by Company, which
approval shall not be unreasonably withheld. Unless Company identifies its
reasons for not approving any person nominated to be Plant Manager in a notice
to Operator delivered within ten (10) Days following Company's receipt of
written notice of such person's nomination by Operator, such person shall be
deemed approved by Company.

            5.2   Plant Personnel. All personnel of Operator providing services
hereunder shall (a) meet minimum job qualifications associated with their
respective positions as determined by Operator, (b) possess experience and
training at least equal to standards generally set within the independent power
industry to carry out the tasks assigned (including, without limitation,
training with respect to handling of hazardous wastes, as Company deems
appropriate, and safety and industrial hygiene as appropriate), and (c) be
trained in accordance with the standards set forth in the Maintenance Program
for the applicable Facility. Operator shall employ competent and experienced
personnel, wherever practicable giving preference to qualified local residents.
Operator shall dedicate sufficient personnel to each Facility throughout the
Term to enable Operator to perform its obligations hereunder.

            5.3   Employee Compensation. The working hours, rates of
compensation and all other labor matters relating to the performance of the
Services by Operator's employees for each Facility shall be determined solely by
Operator, but in a manner consistent with industry standards and rates and the
O&M Budget for the applicable Facility.

            5.4   Fire Prevention. Operator's personnel shall be trained in the
basic elements of fire protection, including measures to ensure the safety of
personnel, the handling of minor fires and situations which may result in a
fire, and in emergency procedures for contacting and obtaining outside fire
fighting capabilities.

<PAGE>

            5.5   Drugs and Alcohol. No personnel of Operator on any Facility
Site shall be under the influence of, or in possession of, any alcoholic
beverage or controlled substance (except as prescribed by a physician, so long
as the performance or safety of the Facility is not affected thereby). Operator
shall implement, maintain and enforce a written alcohol and drug abuse policy
with respect to its personnel, as may from time to time be revised consistent
with Operator's corporate policy. Upon any request by Company, a copy of such
policy then in effect shall be provided to Company.

            5.6   Firearms and Animals. Except as agreed to in writing by
Company and Operator, no personnel of Operator or Company shall carry firearms,

            Company and its representatives shall have access at all reasonable
times to the Facility Sites, Facility operations, and, upon reasonable notice,
documents, materials, records and accounts relating to Facility operations, all
for purposes of inspection and review. During any inspection or review, Company
and its representatives shall comply with all of Operator's safety and security
procedures, and to conduct any inspection or review in a manner causing minimum
interference with Operator's activities. Operator shall cooperate with Company
in allowing other visitors access to the Facility Sites under conditions
mutually agreeable to the parties.

ARTICLE 7. CHANGE ORDERS

            7.1   Change Orders. If at any time during any Calendar Year, either
Operator or Company desires to amend in a material respect the then current
Operating Plan for a Facility for any bona fide purpose, then such party shall
first provide the other party with a notice in writing requesting such
amendment. Within twenty (20) Days of such notice, Operator shall notify Company
of the anticipated increase or decrease in the O&M Budget for such Facility and
the anticipated extent of changes required to the Operating Plan for such
Facility in connection with implementation of such change. Unless implementation
of a Change Order is necessary to avoid or mitigate losses in connection with an
Emergency or liability resulting from a Changed Circumstance, Operator shall not
be permitted or required to materially deviate from the Operating Plan for the
Facility in question until Company and Operator have agreed upon the terms of
the Change Order. If a Change Order is required as a result of an Emergency,
Operator may implement measures necessary to avoid or mitigate losses to such
Facility, but shall obtain Company's approval before incurring expenditures in
excess of fifteen percent (15%) of the current O&M Budget.

            7.2   Agreement. Company and Operator shall endeavor diligently to
reach agreement upon the terms of a Change Order within thirty (30) Days after
the date of receipt of the Change Order request. If agreement is not reached
within that period, the matter will be submitted to the dispute resolution
procedure set forth in Section 16. Notwithstanding any other provision of this
Agreement, in the event of a Changed Circumstance affecting a Facility, Operator
shall not be deemed to be in default of its obligations hereunder for failure to
provide

<PAGE>

Services for such Facility in compliance with Sections 3.2 and 4 of this
Agreement if Company fails to approve a Change Order requested by Operator as a
result of such Changed Circumstance.

            7.3 Variations from the Budget. After variations from the O&M Budget
or changes in the Operating Plan, as appropriate, have been determined pursuant
to Section 7.2, the Change Order shall be signed by both parties and shall
contain a detailed description of the change in the Operating Plan and of any
changes in compensation to Operator required thereby. Upon approval of each
Change Order, the variations from the O&M Budget shall be deemed approved, and
the Operating Plan for the applicable Facility shall be deemed to be so amended.

 ARTICLE 8.   BUDGETS

            8.1   Budgets. In connection with the preparation of the annual
Operating Plan pursuant to Section 3.4, Operator shall also prepare and submit
to Company a proposed annual budget for each Facility for the following Calendar
Year (prepared in monthly detail and in then current dollars) based on the
Operating Plan for each Facility, and Operator's estimate of other costs and
expenses, including work and services provided hereunder on a cost reimbursable
basis. Company shall promptly review Operator's proposed annual budgets and may
request in writing changes, additions, deletions and modifications. Company and
Operator will then meet to agree upon final budgets for each Facility for the
following Calendar Year (for each Facility, such Facility's "O&M Budget") which
shall be subject to approval in writing by both parties. Company's approval of a
final O&M Budget for a Facility must include approval by a director or
financial officer of CGC. An approved final O&M Budget shall remain in effect
for each Facility throughout the applicable Calendar Year, subject to adjustment
or revision as set forth in Sections 8.3, 8.4 and 8.5.

            8.2   Prices For Work. All work and Services provided hereunder will
be provided on a cost reimbursable basis, including reasonable overhead costs.
Operator shall use commercially reasonable efforts to keep third party costs
incurred to reasonable levels, consistent with market prices. Costs payable to
Operator and its affiliates shall not, in the aggregate, exceed costs for
similar goods or services that would normally be charged by unrelated third
parties and shall in no event exceed the prices that Operator charges to
unrelated third parties for such goods or services. The Services provided by
Operator hereunder are for routine operation and maintenance activities. Major
Maintenance activities are covered by a separate agreement between Company and
Operator and are not subject to this Agreement. If Company desires to make
Capital Expenditures, Company and Operator must separately agree on the services
to be provided and the charges therefor.

            8.3   No Approved Budget. If Company has not approved Operator's
proposed O&M Budget for a Facility for a new Calendar Year, or if Operator has
failed to provide such budget in accordance with Section 8.1:

                  (a)   Operator shall nonetheless perform the Services for such
Facility based on the existing O&M Budget for that Facility, as adjusted
pursuant to Section 8.5, except that Operator shall only carry out Capital
Expenditures to such Facility (i) to the extent contracted for with third
parties, and budgeted for in a prior Calendar Year and either reserved

<PAGE>

for or with capital committed by Company, (ii) if such improvements constitute
improvements necessary or appropriate in light of an Emergency as provided in
Section 3.3 (subject to the limitations of Section 8.4), or (iii) if such
improvements are mutually agreed upon by the parties at such time; and

                  (b)   Subject to mutually agreed upon adjustments, Operator
shall be compensated for such Services in accordance with the existing O&M
Budget for such Facility, as adjusted pursuant to Section 8.5, with respect to
all other Services. When an O&M Budget for a Facility is approved after
commencement of the Calendar Year, it shall immediately become effective, and
shall include any adjustments necessary to make it retroactive to the first day
of the Calendar Year.

            8.4   Limitation on Expenditures. The O&M Budget for each Calendar
Year for each Facility shall constitute the control document for that Facility
pursuant to which Operator shall incur expenses on behalf of Company with
respect to such Facility. If at any time during the Calendar Year for a
Facility Operator anticipates an O&M Budget overrun for such Calendar Year in
the aggregate of 15% or greater of the fixed operating expenses (i.e. not
including fuel or other variable expenses and not including costs and expenses
incurred in connection with an Emergency), Operator shall so notify Company in
writing and shall prepare a proposed Change Order for such Facility
incorporating such variation from the affected O&M Budget;

            8.5   Escalation of Budgets. In the absence of contrary information,
the estimated cost of Services for a preliminary O&M Budget shall be made by
increasing each Expense Category in such O&M Budget related to such Services by
the product derived from multiplying each such amount by the Escalation Quotient
for the Calendar Year in which the adjustment occurs, or if the indices for such
year have not yet been published, by the Escalation Quotient derived by using
the indices most recently published as of the date of calculation.

            8.6   Budget Meetings. At Company's request Operator shall meet with
Company

                  (a)   not less frequently than quarterly, to review Operator's
performance under the O&M Budget and Operating Plan for each Facility for such
Calendar Year, and to consider upcoming Capital Expenditures under the O&M
Budget for such Facility and further actions to be taken by Operator in
implementing such Operating Plan; and

                  (b)   from time to time, on an informal basis as reasonably
requested by Company, to review such aspects of Operator's performance with
respect to a Facility as Company specifies.

ARTICLE 9. COMPENSATION

            9.1   Compensation. Operator shall be compensated for the Services
on a cost reimbursable basis, including reasonable overhead costs, as described
in Section 8.2.

            9.2   Reimbursable Expenses. Operator shall be reimbursed for all
costs (including internal costs and amounts paid to third parties) incurred for
Services as provided in

<PAGE>

Article 8. In lieu of making direct payment itself of any costs or expenses
owed to suppliers, vendors, service providers or other third parties for goods
and services provided to the Facilities in connection with the Services
hereunder, Operator may request that Company pay such costs and expenses
directly to such suppliers, vendors, service providers and other third parties,
in which event Company shall do so in a timely manner, provided that such costs
and expenses do not exceed the amounts provided therefor in the O&M Budget (plus
any amounts permitted under Section 8.4). Operator shall give Company as much
prior notice as reasonably possible (which need not exceed thirty (30) Days) in
the event it requests such direct payment by Company and shall review and
approve all invoices from suppliers, vendors, service providers and other third
parties prior to submitting them to Company for payment. No amounts directly
paid by Company as provided herein may be recovered by Operator under this
Section 9.2.

ARTICLE 10. PAYMENT

            10.1  Invoices. Within ten (10) Days after the last Day of each
month after the Effective Date (or, in the case of the Columbia Energy Center
Facility, the Pastoria Energy Center Facility and the Goldendale Energy Center
Facility, the date Services hereunder commence with respect to each such
Facility pursuant to Section 3.1(b)) during the Term, Operator shall send
Company an invoice for each Facility setting forth in reasonable detail the
amount of costs and expenses to be reimbursed and Operator's overhead costs for
such Facility for such preceding month, accompanied by such supporting
documentation and additional data as Company may reasonably request.

            10.2  Payment. Subject to Sections 9.2 and 10.3, within twenty (20)
Days following the date Company receives an invoice for a Facility under Section
10.1, Company shall pay to Operator the undisputed amount of the invoice. All
payments to Operator shall be made by wire transfer to the account of the
Operator, or such other depository as Operator shall designate by written notice
to Company. Any amounts owing from Operator to Company hereunder with respect to
a particular Facility may at Company's option be credited against amounts owing
by Company to Operator hereunder with respect to such Facility.

            10.3  Notice of Payment Disputes. Notwithstanding the foregoing, if
prior to the expiration of the applicable period for payment referenced in
Section 10.2, Company disputes that the quality of any Services provided for a
particular Facility is in accordance with this Agreement, Company shall, prior
to the expiration of such period, provide Operator with written notice
identifying the basis for such dispute. Thereafter, the payment of such disputed
amounts shall be deferred until such dispute has been resolved to the
satisfaction of Company and Operator. Any dispute which is not resolved by
mutual agreement may be resolved in accordance with Section 16.

            10.4  Late Payments. If there is a dispute about any amount invoiced
by Operator, the amount not in dispute shall be promptly paid as described in
this Section 10. Any disputed amounts which are ultimately determined to have
properly payable, as well as any undisputed amounts not paid when due, shall be
paid with interest at the lower of (a) the Reference Rate plus two percent (2%),
or (b) the highest rate permitted under applicable law.

<PAGE>


            10.5  Audit. Operator shall, throughout the Term of this Agreement
and for thirty-six (36) months following the expiration or earlier termination
hereof with respect to each Facility, maintain readily accessible books and
records of the costs and expenses incurred for such Facility (including copies
of supporting invoices) incurred in connection with this Agreement. Company may,
from time to time and upon reasonable notice to Operator, review (or cause its
auditors to review), such books and records.

ARTICLE 11. RESPONSIBILITIES OF COMPANY

            11.1  General. Company shall furnish, or cause to be furnished, to
Operator, at Company's expense, such information, documentation, services,
materials and other items described in this Article 11 with respect to each
Facility, together with such other items that are not required to be provided by
Operator hereunder and which are reasonably requested by Operator to perform the
Services for the applicable Facility and to otherwise fulfill its obligations
under this Agreement. All such items shall be made available at such times and
in such manner as may be required for the expeditious and orderly performance of
the Services by Operator.

            11.2  Notice of Completion. Company shall give immediate written

            11.4  Facilities. Company shall provide necessary facilities at each
Facility for Operator's use in performing the Services for such Facility,
including a furnished and completely equipped office facility, a completely

storage is adequate to protect the same from damage or destruction.

            11.5  Approval. Company shall bear responsibility for reviewing and
approving all required plans, budgets, and schedules for each Facility in a
timely fashion.

            11.6  Parts and Tools. Company shall provide Operator an initial

all equipment, vehicles and operations manuals and procedures that are available
for such Facility, and shall provide, consistently with the inventory lists

tools, supplies, consumables, equipment, vehicles and operations manuals and
procedures.

            11.7  Information. Company shall provide to Operator technical,
operational, and other information relating to each Facility reasonably
available to Company. Subject to the standard of performance of the Services set
forth in Section 4.1, Operator shall be entitled to rely upon such information
in the performance of the Services for such Facility.

<PAGE>

            11.8  Taxes. Company shall have responsibility for payment of all

            11.11. Remedies for Breach of Article 11. In the event of a breach
by Company of any of its obligations under this Article 11 with respect to a
Facility, Operator shall be entitled to suspend its performance hereunder with
respect to such Facility (but only for such Facility) (i) to the extent
prevented or restricted in performing its Services for such Facility by such
breach or (ii) if such breach involves the failure to pay taxes or insurance
premiums with respect to such Facility as provided in Sections 11.8 and 11.9, in
either case until such breach has been cured. Operator shall not be entitled to
terminate this Agreement with respect to the affected Facility on account of a
breach of Company's obligations under this Article 11 unless (i) the breach is
the failure to pay taxes or insurance premiums with respect to such Facility as
provided in Sections 11.8 and 11.9, and such breach is not cured within thirty
(30) Days after written notice thereof to Company or (ii) continued performance
of this Agreement by Operator with respect to such Facility could violate any
applicable Law or could reasonably be expected to subject Operator to
unreasonable liability.

ARTICLE 12. INDEPENDENT CONTRACTOR

            Operator shall be an independent contractor with respect to the
performance of the Services hereunder for each Facility. Neither Operator nor
its employees, subcontractors, vendors or suppliers, or the employees of any
such parties employed in Facility operations, shall be deemed to be agents,
representatives, employees, or servants of Company, except to the extent of any
express agency created hereunder pursuant to the authority granted to Operator
under Section 3. Except as otherwise expressly provided herein, this Agreement
shall not constitute Operator as the legal representative or agent of Company,
nor shall Operator have the right or authority to assume, create or incur any
liability or obligation, express or implied, against, in the name of, or on
behalf of Company or its partners. This Agreement is not intended to create, and
shall not be construed to create, a relationship of partnership or an
association for profit between Company and Operator.

ARTICLE 13. TERM AND TERMINATION

            13.1  Term. This Agreement shall become effective on the Effective
Date and, if not earlier terminated pursuant to this Article 13, shall continue
for ten (10) years (the "Term"), and shall thereafter continue for successive
one-year renewal terms; provided, however, that either party may terminate this
Agreement upon the last day of the initial term or any renewal term by giving
the other party not less than ninety (90) Days' written notice prior to the
scheduled termination date of the initial term or any renewal term.

<PAGE>

            13.2  Termination. Either party hereto may terminate this Agreement
for cause as to a particular Facility upon thirty (30) Days prior written notice
to the other party: (a) in the event of a Bankruptcy Event affecting such other
party (in the case of Company, CGC and the applicable Facility Owner, as
appropriate) or such party's guarantor; (b) subject to Section 11.11, in the
event of a material failure by such other party to perform its obligations
hereunder with respect to such Facility in accordance with the requirements of
this Agreement, if such other party does not cure such breach or failure within
thirty (30) Days of the date of a notice from the first party demanding such
cure (or within such longer period of time as is reasonably necessary to
accomplish such cure, but not to exceed ninety (90) Days in the aggregate, if it
cannot be reasonably accomplished within such thirty (30) Day period and such
other party diligently commences and continues such cure in such period), or (c)
a party's guarantor shall repudiate, disaffirm, disclaim, or reject, in whole or
in part, or challenge the validity of the guaranty. Notwithstanding any
provision herein to the contrary, no failure of Operator to do any act or
perform any Services for a particular Facility that results from lack of
required approval by Company shall be deemed a breach of this Agreement. For the
avoidance of doubt, Company and Operator agree that an event giving rise to a
right to terminate this Agreement with respect to one Facility shall not give
Company or Operator, as applicable, the right to terminate this Agreement with
respect to another Facility unless such event or another event independently
gives such party the right to terminate this Agreement with respect to such
other Facility.

            13.3  Termination Dispute. If the parties disagree as to the
materiality of any claimed default, or as to the applicability of any cure
period, or as to the adequacy of any cure, said disagreement shall be submitted
to an advisory panel selected in accordance with Section 16 of this Agreement,
which shall be charged with preparing a non-binding written appraisal of such
disagreement, to be issued as soon as practicable by said advisory panel and in
any event within thirty (30) Days of its selection. In the event the parties are
unable to resolve their dispute or disagreement within ten days following their
receipt of the advisory panel's written appraisal, then either party may submit
such dispute or disagreement for resolution by binding arbitration under the
rules of the American Arbitration Association ("AAA"). as set forth in Article
16.2 of this Agreement.

            13.4  Termination for Convenience. Company shall have the right,
during the Term hereof, to terminate this Agreement with respect to any
Facility, without cause (including upon the sale of a Facility), upon ninety
(90) Days prior written notice to Operator and payment of the amounts described
in Section 13,6. If Company elects to terminate this Agreement pursuant to this
Section 13.4 as to a particular Facility, the parties shall confer and set out a
description of the activities required in order to terminate this Agreement with
respect to such Facility in an orderly manner, including matters addressed in
Section 13.5. At Company's request, from the date of the termination notice
through the effective date of termination (the "Transition Period"). Operator
will continue to operate and maintain the applicable Facility, assist in
training a replacement Operator and perform such other transition work as
Company may reasonably request. During the Transition Period, Operator shall be
paid with respect to the applicable Facility in accordance with Section 9.1. In
addition, upon the effective date of a termination of this Agreement with
respect to a Facility pursuant to this Section 13.4, Company shall pay to
Operator, in addition to the amounts described in the preceding sentence, the
amounts specified in Sections 13.5 and 13.6.

<PAGE>

            13.5  Facility Condition at End of Term. Upon expiration or
termination of this Agreement with respect to a Facility, Operator shall remove
its personnel from the applicable Facility Sites and shall leave such Facilities
in good condition, normal wear and tear and any other degradation for which
Operator is not responsible excepted. All special tools, improvements, inventory
of supplies, spare parts, safety equipment, operating and maintenance manuals
and procedures, operating and financial records and any other items furnished
under this Agreement with respect to such Facility shall be left at the
applicable Facility Site and shall remain the property of Company without
additional charge. Company also shall have the right, in its sole discretion, to
directly assume and become liable for any contracts or obligations related to
the terminated Facility that Operator may have undertaken with third parties,
with such third party's consent, in connection with the Services for such
Facility, and Operator shall execute all documents and take all other reasonable
steps required by Company which may be required to assign to and vest in Company
all rights, benefits, interests and title in connection with such contracts or
obligations. If Company elects not to directly assume or become liable for any
such contracts or other obligations with respect to a terminated Facility,
Company shall reimburse Operator for any additional costs reasonably incurred by
Operator in connection with the termination or other discharge of such contracts
or obligations with respect to such Facility, if such contracts or obligations
have been entered into or incurred by Operator in accordance with the provisions
of this Agreement.

            13.6  Termination Payment. In the event of a termination of this
Agreement as to a particular Facility pursuant to Section 13.2 (if Company was
the defaulting party) or Section 13.4, Operator shall be entitled, in addition
to all other amounts due to it hereunder as of the date of termination, to
receive a termination payment equal to all costs and expenses reasonably
incurred by Operator as a direct result of such termination, including (a) all
relocation and severance costs incurred with respect to Operator's employees at
the applicable Facility which Operator is contractually or legally obligated to
pay to its employees (other than pursuant to any "golden parachute" or other
like provisions contained in such contracts) or which are incurred with the
prior written consent of Company in accordance with established personnel
policies of Operator, and (b) the cost reasonably incurred by Operator in
withdrawing from the applicable Facility and otherwise demobilizing its
operations with respect to such Facility. Such amounts shall be due and payable
by Company within thirty (30) Days of Operator's submission of an invoice
therefor.

            13.7  Effect of Termination. No termination of this Agreement shall
deprive a party of amounts or other performance due to such party for any period
prior to the date of such termination, or relieve any party of the consequences
of its breach of this Agreement. Election to terminate this Agreement with
respect to a Facility pursuant to Section 13.2 shall not constitute an election
of remedies and, subject to Article 14, shall be without prejudice to any other
remedies at law or in equity available to the non-defaulting party by reason of
any default of the other party. For the avoidance of doubt, Company or Operator,
consistently with such party's rights under this Agreement, may elect to
terminate this Agreement with respect to a particular Facility due to a breach
or default of the other party with respect to such Facility, in which case this
Agreement shall terminate as to such Facility, but such termination shall not
affect the rights and obligations of Company and Operator with respect to the
other Facilities, and this Agreement shall continue in force with respect to
those other Facilities.

ARTICLE 14. INDEMNIFICATION; LIMITATION OF LIABILITY

            14.1  Operator Indemnification. Subject to Sections 14.4 and 14.5,
with respect to each Facility, Operator shall defend, indemnify and hold Company
and its Indemnitees harmless from and against any and all claims, actions,
damages, expenses (including reasonable attorneys' fees), losses or liabilities
incurred by or asserted against Company or its Indemnitees for injury (including
death) to persons or damage or destruction to property and any and all fees or
penalties incurred by Company, including damages arising from environmental
contaminants, to the extent that such claims, actions, damages, expenses,
losses, liabilities, including damages arising from environmental contaminants,
are caused by Operator's breach of this Agreement or the negligence or willful
misconduct of Operator, its Affiliates, employees, partners, agents, officers or
directors.

            14.2  Company Indemnification. Company shall defend, indemnify and
hold Operator and its Indemnitees harmless from and against any and all claims,
actions; damages, expenses (including reasonable attorneys' fees), losses or
liabilities incurred by or asserted against Operator or its Affiliates,
officers, directors, employees or agents with respect to any Facility to the
extent that such claims, actions, damages, expenses, losses or liabilities are
caused by the negligence or willful misconduct of Company, its Affiliates,
employees, partners, agents, officers or directors.

            14.3  Environmental Indemnification. Company also shall defend,
indemnify and hold Operator and its Indemnitees harmless from and against any
and all claims, actions, damages, fines, penalties, expenses (including those
actions asserted by any governmental or regulatory body) incurred by or asserted
against Operator or its Indemnitees that arise out of or result from any
environmental contamination of any Facility or the property of any third party,
whether arising before or after the Effective Date, except, as to any such
contamination or failure occurring after the Effective Date, to the extent that
such claims, actions, damages, fines, penalties or expenses arise directly from
Operator's negligence or willful misconduct.

            14.4  Limitation of Liability. Notwithstanding any provision in this
Agreement to the contrary, no party nor its Indemnitees shall be liable
hereunder for consequential or indirect loss or damage, including loss of
project revenues, cost of capital, loss of goodwill, increased operating costs,
or any other special, incidental or punitive damages; provided, however, that
the foregoing limitation shall not apply to damages resulting from the willful
misconduct of a party hereto; provided, further that nothing in this sentence
shall limit the obligations of Company and Operator under this Article 14 to
indemnify the other party with respect to claims by third parties otherwise
covered by the provisions of this Article 14. Operator's maximum cumulative
liability under this Agreement with respect to a particular Facility, including
liability for matters resulting from Operator's breach of this Agreement with
respect to such Facility, shall be limited to $100,000 with respect to each
Facility during each Calendar Year in which liability is sought to be imposed;
provided, however, that the foregoing limitation of liability shall not apply to
damages resulting from Operator's willful misconduct, and provided further that
Operator shall not be liable to the extent that a liability is covered by the
proceeds collected under any policy of insurance then in force with respect to
the Services performed for such Facility, with respect to which the insurer has
waived subrogation against Operator (which proceeds shall be applied directly to
satisfy Operator's liability under this

<PAGE>

Agreement). The parties agree that, except for such liability, Company's only

<PAGE>

accordance with the rules of the American Arbitration Association; provided that
unless otherwise agreed between the parties there shall be three arbitrators who
are disinterested persons of recognized competence in the area at issue, one
named in writing by each of the parties within ten days after demand for
arbitration is made, and a third to be chosen by the two so named within thirty
(30) Days after demand for arbitration is made. Should either party refuse or
neglect to join in the appointment of the arbitrators, the arbitrator selected
by the other party shall be the sole arbitrator of the dispute. The place of
arbitration shall be San Jose, California, unless in any particular case the
parties agree upon a different venue. The award of the arbitrators shall be
final and binding upon the parties, and judgment thereon may be entered in any
court having jurisdiction thereof.

(b) the reasonable attorneys' fees of such other party, and (c) any other
reasonable out-of-pocket expenses incurred by such other party in connection
with the arbitration proceeding. In all other instances, each party shall pay
for its own costs and expenses arising out of any arbitration, with the cost of
any third arbitrator being shared equally by the parties.

            16.4  No Interruption. The pendency of these dispute resolution
procedures shall not in and of itself relieve either party from its duty to
perform under this Agreement with respect to the affected Facility or serve to
delay or suspend the operation of such Facility or the performance of the
Services hereunder with respect to such Facility or any other Facility.

ARTICLE 17. FORCE MAJEURE

            17.1  Excuse for Force Majeure. A delay in or failure of performance
hereunder by either party shall be excused to the extent caused by Force
Majeure, with the exception of payment obligations. The foregoing provisions
allowing a party to claim excuse due to Force Majeure shall not relieve such
party from using its reasonable efforts to overcome or remove such Force
Majeure. A party claiming such failure or delay shall give prompt notice thereof
to the other party, together with a description of such efforts to overcome the
Force Majeure.

            17.2  Legal Changes. In the event a party is unable to perform due
to legislative, judicial, or regulatory agency action affecting a particular
Facility, this Agreement shall be amended as appropriate with respect to such
Facility to comply with the legal change, which caused the non-performance.
