prompt written notice of the scheduled and actual date of Financial Closing.
Section 4.09. Owner Taxes. Owner shall pay all real property taxes
assessed against the Property Site and any permanent use charges or
assessments such as water or sewer (but excluding charges and taxes for
construction utilities and fuel to be supplied by Contractor as required
hereunder, which shall be Contractor's responsibility), and Owner shall be
responsible for the payment of, or reimbursement to Contractor of, state or
local sales and/or use or excise taxes in connection with the purchase of any
equipment (including rentals, leases and consumables), except for such taxes
Owner contests in good faith (collectively, "Owner Taxes"). In the event
that Owner is required to pay additional state or local taxes because
Contractor failed to follow written instructions of Owner appropriately,
Contractor shall be responsible for the cost of such additional taxes.
Section 4.10. Owner's Cooperation. Owner shall cooperate in all
material respects to permit Contractor to perform its obligations hereunder
and shall make reasonable efforts to supply to Contractor, in a timely
manner, either directly or indirectly, material information and data that is
available to Owner and that is required for the performance of the Work.
Section 4.11. Owner's Representative. Owner shall designate in writing
one or more representatives at the Property Site (at least one of whom shall
be at the site during normal business hours) who shall have authority to
administer this Agreement on behalf of Owner, approve Contractor's
submissions hereunder and inspect the Work, as reasonably necessary for
Contractor's performance of the Work. Notwithstanding the foregoing,
Owner's Representative shall not have authority to approve Change Orders.
Section 4.12. Turbine Vendor Purchase Agreement. On the Financial
Closing Date, Owner shall execute the Turbine Vendor Assignment and
Assumption Agreement and shall use all reasonable efforts to have the Turbine
Vendor execute the Turbine Vendor Assignment and Assumption Agreement.
Contractor agrees to consent to such changes to the Turbine Vendor Assignment
and Assumption Agreement as reasonably requested by the Financing Parties.
Prior to assignment of the Turbine Vendor Purchase Agreement to Contractor,
(a) Owner agrees to make all payments to the Turbine Vendor thereunder when
and as due, and (b) Owner shall not amend or otherwise modify the Turbine
Vendor Purchase Agreement without the prior written consent of Contractor.
Section 4.13. Operation and Maintenance. Owner shall timely provide
operators having reasonable experience and qualifications for training and
for the operation of the Plant to support start-up and testing of the Plant
and to participate in the training of O&M Personnel by Contractor. From and
after the Commercial Operation Date for each Phase, Owner shall provide, or
cause to be provided, operation and maintenance of such Phase.
ARTICLE V
PROJECT SCHEDULE
Section 5.01. Commencement of Work. After the date hereof, Contractor
will commence performance of the Work so as to ensure completion of the Work
in accordance with the terms hereof. The Parties agree that any and all Work
performed prior to the Financial Closing Date (the "Prefunding Work"), except
to the extent required pursuant to a Notice to Proceed as set forth below and
except to the extent Contractor is entitled to reimbursement pursuant to
Section 7.02, shall be solely at Contractor's expense and risk, without right
of payment until the earlier of December 20, 1998, or Financial Closing. If
Financial Closing occurs by December 20, 1998, Contractor shall be entitled
to reimbursement pursuant to Section 7.02 and shall also be entitled to
recover demonstrated internal costs expended prior to that date. If
Financial Closing has not occurred by December 20, 1998, Owner shall have the
right to require Contractor to continue performing all or a portion of the
work prior to Financial Closing by giving Contractor a Notice to Proceed. In
such an event, Contractor shall be entitled to recovery of 50% of all
demonstrated Contractor Internal Costs expended prior to that date and 100%
of all such costs expended after December 20, 1998 (such amounts to be
invoiced and paid on a monthly basis). If Financial Closing occurs, all
payments hereunder shall be credited to the original Separated Contract Price
as listed in Exhibit J and no additional compensation or Change Orders shall
be warranted. In the event Financial Closing does not occur by July 1, 1999,
Contractor may suspend its services or the Parties may otherwise continue as
mutually agreed. Without limiting Contractor's obligations regarding the pre-
funding work, whether or not Owner has given Contractor a Notice to Proceed,
Contractor shall commence full performance of the work no later than the
Financial Closing date.
Section 5.02. Project Schedule.
(a) Contractor shall perform the Work in compliance with the Project
Schedule, including completing the Work required by the Guaranteed Commercial
Operation Dates and the Final Acceptance Date. Contractor hereby covenants
and warrants to Owner that in undertaking to complete the Work in accordance
with the terms hereof, Contractor has taken into consideration and made
reasonable allowances for hindrances and delays incident to such Work.
Contractor shall provide the reports as required herein, and provide any
further information required by Owner as Owner, the Financing Parties or the
Facilities Engineer may reasonably request to verify actual progress and
forecast future progress of the Work. Contractor shall promptly notify Owner
in writing of any occurrence that Contractor has reason to believe will
adversely affect the completion of the Work by the Guaranteed Commercial
Operation Dates or materially adversely affect completion of the Work in
accordance with the Project Schedule. Contractor will specify in said notice
the corrective action planned by Contractor with respect thereto.
(b) Without limiting the obligations of Contractor under Section
5.02(a), Contractor shall provide together with its monthly status reports
required hereunder any revisions to the Project Schedule that provide for the
orderly, practicable and expeditious completion of the Work in accordance
with the requirements of this Agreement. Each revised Project Schedule shall
be presented in such reasonable detail as Owner and the Facilities Engineer
may require and shall address all material elements of the Work. Contractor
shall consult with Owner in connection with each revision to the Project
Schedule provided under this paragraph. Notwithstanding anything contained
herein to the contrary, in the absence of a Change Order, no revision to the
Project Schedule shall in any way amend, alter or otherwise change the
Guaranteed Commercial Operation Date.
(c) When the Contractor becomes aware that Critical Milestone Number
1, 2, or 3 (Exhibit C) will not be achieved by the date required, Contractor
shall provide to Owner a written recovery plan that will demonstrate
achievement of the Milestone at the earliest possible date to minimize delay
of the Project Schedule.
(d) Upon the failure of Contractor to achieve Mechanical Completion of
Phase I by April 1, 2000, as that date may be extended pursuant to Article
VI, Contractor shall, within three days thereafter, submit a recovery plan,
which shall reasonably demonstrate the steps Contractor will take to achieve
Mechanical Completion of Phase I at the earliest date and Phase I Commercial
Operation by December 1, 2000. In addition, the Parties will mutually agree
upon and hire an Independent Engineer who will evaluate Contractor's recovery
plan and the completion status of Phase I. Costs of the Independent Engineer
shall be borne by Contractor. The Independent Engineer shall render a
written opinion within thirty (30) days as to the adequacy of Contractor's
recovery plan and whether or not Contractor will be able to achieve Phase I
Commercial Operation by December 1, 2000. If the Independent Engineer
confirms the Contractor's recovery plan, Contractor shall not be in default
of this Agreement and shall continue working to prosecute the work. If the
Independent Engineer does not, in its reasonable professional opinion,
believe that Contractor will be able to achieve Phase I Commercial Operation
by December 1, 2000, then, and in that event, Contractor shall have a period
of no more than thirty (30) days thereafter to demonstrate to the Independent
Engineer the efficacy of Contractor's recovery plan. To the extent
Contractor is unsuccessful in demonstrating the efficacy of Contractor's
recovery plan to achieve Phase I Commercial Operation by December 1, 2000 (as
that date may have been extended pursuant to Article VI), Contractor shall be
in default of this Agreement and Owner shall have the right, but not
obligation, to terminate Contractor's services pursuant to Article XV.
If Contractor does not achieve Phase I Commercial Operation by the Phase I
Guaranteed Commercial Operation Date, Contractor shall pay Schedule
Liquidated Damages as provided in Section 11.02. In that event, an
Independent Engineer shall employ the procedures set out in the previous
paragraph; provided however, in that instance the Independent Engineer shall
render an opinion within fifteen (15) days as to the adequacy of Contractor's
Recovery Plan, and in the event the Independent Engineer does not believe
that the Contractor will be able to achieve Phase I Commercial Operation by
December 1, 2000, then, in that event, Contractor shall have a period of
fifteen (15) days thereafter to demonstrate to the Independent Engineer the
efficacy of Contractor's Recovery Plan.
(e) In no event will the Contractor's failure to complete one or more
Milestones by the date required for such Milestone change, delay or otherwise
affect the required completion date for any other Milestone. Nothing
contained in this Article V shall relieve Contractor from its obligation to
pay Schedule Liquidated Damages in the event that Commercial Operation for
each Phase is not achieved by the applicable Guaranteed Commercial Operation
Date.
Section 5.03. Certain Prefunding Work. Without limiting the provisions
of Sections 5.01 and 5.02, the following provisions shall apply to certain
Prefunding Work:
(a) Contractor agrees to perform design and engineering services from
the date hereof so that completion of the Work will occur in accordance with
the Project Schedule, the Guaranteed Commercial Operation Dates and the other
terms hereof. The Parties agree that in the event this Agreement is
terminated prior to the earlier of Financial Closing or December 20, 1998,
for any reason, Contractor shall not be compensated or reimbursed for any of
the design and engineering services performed hereunder, including, without
limitation, any Contractor Internal Costs incurred or accrued by Contractor
in connection therewith.
(b) Subject to the terms of Section 2.03 and this paragraph (b),
commencing on the date hereof, Contractor shall enter into purchase orders
and agreements with Subcontractors and Vendors for Equipment so that
completion of the Work will occur in accordance with the Project Schedule,
the Guaranteed Commercial Operation Dates and the other terms hereof. In
order to minimize any costs associated with cancellation of such purchase
orders and agreements for Equipment between Contractor and its
Subcontractors and Vendors entered into prior to the Financial Closing Date
(the "Prefunding Purchase Orders"), Contractor shall use all reasonable
efforts to have included therein "no harm/no foul" provisions. As used
herein, "no harm/no foul" provisions mean that the Subcontractor or Vendor
shall use all reasonable efforts to sell the Equipment subject to the
purchase order or agreement to another purchaser at a commercially
reasonable price, and the proceeds thereof shall be used to offset any
amounts owing to such Subcontractor or Vendor upon the cancellation of such
purchase order or agreement. Contractor shall not enter into any Prefunding
Purchase Orders without the prior review and written approval of Owner
(including, without limitation, approval of any cancellation provisions
associated therewith), which approval shall be reasonably given under the
circumstances in order to permit Contractor to maintain the Project Schedule.
In the event that this Agreement is terminated prior to the Financial
Closing, the Parties agree that Contractor shall be entitled to reimbursement
for Total Prefunding Costs incurred pursuant to the terms of Section 7.02.
ARTICLE VI
CHANGE ORDERS
Section 6.01. Change Order at Owner's Request.
(a) Owner may at any time, by written notice to Contractor, request an
addition to or deletion from or other changes in the Work (together with any
necessary or requested amendments to this Agreement with respect thereto)
(hereinafter "Change" or "Changes"). Contractor shall reasonably review and
consider such requested Change and shall make a written response thereto
within fourteen (14) days after receiving such request. If Contractor
believes that giving effect to any Change requested by Owner will increase or
decrease its cost of performing the Work, shorten or lengthen the time needed
for completion of the Work, require modification of its warranties in Article
XII or require a modification of any other provisions of this Agreement, its
response to the Change request shall set forth such changes (including any
amendments to this Agreement) that Contractor deems necessary as a result of
the requested Change and its justification therefor. In the event that
Contractor fails to respond to Owner's request for a Change or notify Owner
of any changes as to cost, schedule, warranty obligations or other provisions
hereof resulting from the requested Change within fourteen (14) days after
receiving Owner's request for such Change, Contractor shall be deemed to have
accepted the requested Change as specified by Owner (including any amendments
hereto specified therein, if any) unconditionally and without additional
consideration or other amendments hereto (except as specified by Owner in its
request), in which event such requested Change shall be deemed to be a Change
Order and Contractor shall have waived any claims or offsets against Owner as
a result of the Change Order; provided that if such changes as to cost,
schedule, warranty obligations or other provisions hereof cannot be
determined within the specified fourteen (14) day period, and Contractor
submits a notice to Owner within such fourteen (14) day period that the
requested Changes will have an effect on costs, schedule, warranty
obligations or other provisions hereof and provides the expected date (which
shall be as soon as reasonably practicable) for its response with respect
thereto, the requested Change shall not become a Change Order so long as
Contractor provides such information as to the effect on costs, schedule,
warranty obligations and other provisions hereof by the date specified by
Contractor. If Contractor accepts the Changes requested by Owner (together
with any amendments to this Agreement specified therein), or if the Parties
agree upon a modification of such requested Changes, the Parties shall set
forth the agreed upon Change in the Work and agreed upon amendments to this
Agreement, if any, in a written change order signed by all Parties (a "Change
Order").
(b) Owner may at any time, by written notice to Contractor, propose
Changes in the Work or the Project Schedule due to a Force Majeure Event or
an Owner Caused Delay. If there is a material impact on Work or the
Project Schedule as a result of such Force Majeure Event or an Owner Caused
Delay, then the Parties agree to bargain reasonably and in good-faith for the
execution of a mutually acceptable Change Order, except as provided in
Section 14.03, Contractor will be limited to extensions of the Project
Schedule only for Force Majeure Events.
Section 6.02. Change Orders Requested by Contractor.
(a) It is the intent of the Owner and Contractor that the Scope of Work
attached hereto as Exhibit "A" includes all items necessary for the proper
execution and completion of the Work. Work not described in the Scope of
Work attached hereto as Exhibit "A" will not be required without a Change
Order unless that work is consistent with and reasonably inferable from the
Scope of Work, so that a design-build contractor of Contractor's experience
and expertise should have anticipated that the work would have been required.
(b) Subject to paragraphs (b) and (c) below, Contractor may at any
time, by written notice to Owner, request a Change in the Work (together with
any necessary or requested amendments to this Agreement). If Contractor
believes that such requested Change will increase or decrease its cost of
performing the Work, lengthen or shorten the time needed for completion of
the Work, require modification of its warranties in Article XII or require a
modification of any other provisions of this Agreement, it shall notify Owner
of such, setting forth its justification for and effect of such changes,
within ten (10) days after making a request for a Change. In the event that
Contractor does not provide a written notice to Owner specifying the effect
of such requested Changes as to cost, schedule, warranty obligations or other
provisions hereof within ten (10) days after giving written notice of a
requested Change, and if Owner approves of the requested Change, then such
requested Change shall be deemed to be a Change Order as specified by
Contractor in its initial request (including any amendments hereto specified
therein, if any) unconditionally and without additional consideration or
other amendments hereto (except as specified by Contractor in its initial
request), and Contractor shall have waived any claims or offsets against
Owner as a result of such Change Order. If Owner accepts the Changes
requested by Contractor (together with amendments to this Agreement specified
therein, if any), or if the Parties agree upon a modification of such
requested Changes, the Parties shall set forth the agreed upon Change in the
Work and agreed upon amendments to this Agreement, if any, in a written
Change Order signed by all Parties.
(c) Contractor may at any time, by written notice to Owner, propose
Changes in the Work or the Critical Milestones (i) due to a Force Majeure
Event, provided that such Force Majeure Event has an impact that will
actually, demonstrably, adversely and materially affect Contractor's
ability to complete one or more Milestones by the required dates, (ii) due to
an Owner Caused Delay, provided that such Owner Caused Delay has a
demonstrable material cost increase to Contractor and/or schedule impact that
will actually, demonstrably, adversely and materially affect Contractor's
ability to complete one or more Milestones by the required dates or (iii) due
to a Change In Law, provided that such Change In Law prevents Contractor from
performing all or a portion of the Work, has a demonstrable material cost
increase to Contractor and/or has a schedule impact that will actually,
demonstrably, adversely and materially affect Contractor's ability to
complete one or more Milestones by the required dates. Unless the foregoing
conditions are met, Contractor may not request a Change in the Work or
Critical Milestones due to a Force Majeure Event, Owner Caused Delay or
Change In Law. If Owner agrees that Contractor has met all of the applicable
condition precedents for a requested Change, then the Parties agree to
bargain reasonably and in good faith for the execution of a mutually
acceptable Change Order. If in such event the Parties are unable to agree on
a mutually acceptable Change Order, then the dispute shall be resolved in
accordance with Article XVII, except as otherwise provided in Section 6.03,
and except as provided in Section 14.03, Contractor will be limited to
extensions of the Project Schedule only for Force Majeure Events.
(d) If Contractor knows of circumstances or events that do or may
require a Change in the Work or Project Schedule, and Contractor does not
provide written notification to Owner of such within ten (10) days after the
date Contractor knows of such circumstances or events, then Contractor shall
not have any right to request or require any additional consideration or
other changes as to cost, schedule, warranty obligations or other provisions
hereof, and Contractor shall have waived any claims or offsets against Owner,
with respect to any Change Order or any necessary Change in the Work or
Project Schedule arising out of such circumstances or events.
(e) The cost of Change Orders shall be determined as provided in the
attached Exhibit K.
Section 6.03. Changes to Separated Contract Price; Disputes. A Change
Order initiated by either Party may have the effect of either increasing or
decreasing the Separated Contract Price. Any Contractor response to a Change
Order under Section 6.01 and any Contractor request for Changes under Section
6.02, shall be accompanied by a proposed all-inclusive final lump sum cost
(separating materials and labor) to Owner. In the event that the Parties are
unable to reach an agreement on an all inclusive final lump sum cost to Owner
as a result of a requested Change, then Contractor agrees to perform the
requested Change using the Contractor's Rate Schedule pending resolution of
the dispute pursuant to Article XVII. In addition, in the event that Owner
and Contractor are unable to reach agreement on a Change Order for a Change
requested by either Owner or Contractor, at the direction of the Owner
(and only at the direction of Owner), Owner's proposed Changes shall become
effective as a Change Order and Contractor shall continue to perform the Work
in accordance with such Change Order and the proposed Changes shall be
performed per Contractor's Rate Schedule pending resolution of the dispute
pursuant to Article XVII.
Section 6.04. Information Requests. Owner may request that
Contractor provide written information (prior to the issuance of a request
for Changes) regarding the effect of a contemplated Change on pricing,
scheduling, warranty obligations or on other terms of the Agreement. The
purpose of such a request will be to determine whether or not a Change
will be requested. Contractor shall provide the requested information
within fourteen (14) days after the receipt of said request. Contractor
will be allowed to reasonably delay its response to such request to the
extent that fulfilling such request would significantly delay progress on
the Work, unless Owner agrees to extend the required completion date for
the affected Milestone. Such an information request is not a Change Order
and does not authorize Contractor to commence performance of the
contemplated change in Scope of Work.
ARTICLE VII
SEPARATED CONTRACT PRICE; PAYMENTS TO CONTRACTOR
Section 7.01. Separated Contract Price. Owner shall pay Contractor the
Separated Contract Price, which will separately state the cost for materials
and labor, as full payment for all Work to be performed by Contractor under
this Agreement. The following amounts that may be payable to Contractor
pursuant to the terms hereof are in addition to the Separated Contract Price:
(i) any Early Completion Bonus and/or Performance Bonus; (ii) interest
payable on delayed payments by Owner hereunder; (iii) sales tax
reimbursement, if any, pursuant to Section 3.24; and (iv) internal costs
payable to Contractor pursuant to Section 5.01. Except as expressly provided
in herein, payments of the Separated Contract Price shall be made based on
completion of Milestones in accordance with the Milestone Payment Table
("Milestone Payments"), subject to the terms and conditions hereof.
Section 7.02. Prefunding Costs.
(a) Prior to the tenth (10th) day of each month prior to the Financial
Closing Date, Contractor shall submit a statement to Owner that contains the
following information: (i) all Contractor Internal Costs incurred the
previous month, (ii) all Prefunding Third Party Costs incurred or accrued
during the previous month and to date, and (iii) all cancellation costs under
Prefunding Purchase Orders accrued or for which Contractor became
contingently liable for during the previous month and to date. Such
statements shall include separate line items for material and labor costs, if
any. In addition, Contractor shall submit to Owner appropriate and
reasonable documentation to evidence and support the amounts set forth in
each statement. Upon request by Owner, Contractor shall promptly provide
additional supporting documentation as reasonably necessary to support
Contractor's statement. Amounts indicated in such statements shall be due
and payable in accordance with the terms of this Section 7.02.
(b) In the event that this Agreement is terminated prior to Financial
Closing, Contractor shall promptly submit a statement to Owner that contains
the following information: (i) all Prefunding Third Party Costs incurred
since the end of the previous month through the termination date, (ii) all
Prefunding Cancellation Costs actually incurred by Contractor, and (iii)
Contractor's Internal Costs that are due pursuant to Section 5.01. Such
statements shall include separate line items for labor costs and materials
costs. Contractor shall submit to Owner appropriate and reasonable
documentation to evidence and support the amounts set forth in such invoice.
Upon request by Owner, Contractor shall promptly provide additional
supporting documentation as reasonably necessary to support Contractor's
invoice. Within thirty (30) days after receipt of such statement, provided
that Contractor has delivered all Lien waivers requested by Owner in
accordance with Section 7.06(c), Owner shall reimburse Contractor for the
Total Prefunding Costs actually incurred that remain after the deducting
amounts that Owner disputes as not being due and owing. After December 20th,
assuming the Contractor has received a Notice to Proceed as provided herein,
Contractor shall be paid on a monthly basis for all third party costs
incurred even if Financial Closing does not ultimately occur.
Section 7.03. Financial Closing Payment. At least three (3) Business
Days prior to the Financial Closing Date, Contractor may submit to Owner a
Request For Payment reflecting (a) all Pre-funding Third Party Costs actually
incurred; (b) each Milestone completed prior to Financial Closing; and (c)
all internal costs incurred prior to December 20, 1998 less amounts paid, if
any, and all unpaid internal costs incurred after December 20, 1998 and prior
to Financial Closing if, in any event, Contractor received written notice to
continue work after December 20, 1998 and prior to Financial Closing
(separating materials and labor) for each Milestone (other than Turbine
Vendor Milestones) completed prior to the Financial Closing Date. At
Financial Closing (and only at Financial Closing), provided that Contractor
has delivered all Lien waivers requested by Owner in accordance with Section
7.06(c), the duly executed Parent Guaranty and all other documents reasonably
required by the Financing Parties, Owner shall pay to Contractor the amount
that remains after the deducting from the Milestone Payments requested any
amounts that Owner disputes as not being due and owing.
Section 7.04. Post Financial Closing. Commencing after the Financial
Closing Date, prior to the tenth (10th) day of each month following any month
in which the Contractor achieves completion of a Milestone, Contractor may
submit to Owner a Request For Payment (separating materials and labor) for
each Milestone completed during the previous month. Each Request For Payment
shall be accompanied by a Milestone Achievement Certificate, duly executed by
the Contractor Project Manager, and a Milestone Payment Certification duly
executed by the Contractor Site Manager and Owners representative (if
approved), for each Milestone completed. Within thirty (30) days after its
receipt of a Request For Payment, provided that Contractor has delivered all
Lien waivers requested by Owner in accordance with Section 7.06(c), Owner
shall pay to Contractor the amount that remains after the deduction from the
Milestone Payment requested of the following amounts: (i) any portion thereof
that Owner disputes as not being due and owing, (ii) any overpayment made by
Owner for any previous period, and (iii) any Schedule Liquidated Damages and
Performance Liquidated Damages (including interest thereon) payable by
Contractor.
Section 7.05. General Provisions Payments.
(a) If applicable, any payment by Owner shall be accompanied by a
notice to Contractor specifying the amount of each deduction and setting
forth the reason(s) why the deduction is justified. If any such amount
deducted from the requested amount is subsequently determined, by agreement
of the Parties or by arbitration pursuant to Article XVII, to have been
unjustifiably so deducted, Contractor shall be entitled to payment of such
amount, plus interest thereon at the Reference Rate from the date that such
amount should have been paid until the date of such payment. Pending the
resolution of any disputed Milestone Payment or invoice submitted
hereunder, Contractor shall continue performance of the Work.
(b) Failure or forbearance on the part of Owner in withholding any
amounts due under a Milestone Payment or invoice shall not be construed as
accepting or acquiescing to any disputed claims. In addition, the making of
any Milestone Payment by Owner shall not constitute an admission by it that
the Work covered by such payment (or any Work previously performed) is
satisfactory or timely performed, and Owner shall have the same right to
challenge the satisfactoriness and timeliness of such Work as if it had not
made such payment. If, after any such payment has been made, it is
subsequently determined that Contractor was not entitled to all or a portion
of any such payment, Contractor shall promptly refund all or a portion of
such payment to Owner with interest thereon at the Reference Rate from the
date that Contractor received such payment to the date of refund.
(c) Notwithstanding any other provision to the contrary contained
herein, Owner shall have no obligation to make payments to Contractor
hereunder at any time when Contractor is in breach of this Agreement. Owner
shall release payments withheld pursuant to this Section 7.05(c) when
Contractor cures all such breaches to the satisfaction of Owner.
(d) Each payment made pursuant to this Article shall be paid directly
to Contractor. Such payment shall be wire-transferred to an account or
accounts designated by Contractor in its Request For Payment.
Section 7.06. Financing Parties' Requirements and Lien Waivers.
(a) Contractor acknowledges that Owner will borrow certain funds from
the Financing Parties for the construction of the Plant and that, as a
condition to making loans to Owner, the Financing Parties may from time to
time require certain documents from Contractor and its Subcontractors and
Vendors. In connection therewith, Contractor agrees to furnish to the
Financing Parties, and to use its best efforts to cause its Subcontractors
and Vendors to furnish to the Financing Parties, such written information,
certificates, copies of invoices and receipts, lien waivers (upon payment),
affidavits and other like documents as the Financing Parties may reasonably
request. Upon the request of the Financing Parties, as a condition
precedent to Financial Closing, Contractor shall state in writing whether or
not it is satisfied with Owner's performance to that date.
(b) Contractor shall promptly execute any additional documentation as
may be reasonably requested by the Financing Parties, including, but not
limited to, documents evidencing Contractor's consent to assignment of this
Agreement as a security to the Financing Parties or otherwise upon the
occurrence of events specified in such documents and any reasonable
modifications to this Agreement.
(c) As a condition precedent to the making of any payment hereunder,
Owner shall require that Contractor and each of its Substantial
Subcontractors and Substantial Vendors provide Owner with a certificate (in
substantially the form as Exhibit H and Exhibit H-1 attached hereto)
stating that all amounts due to Contractor and its Subcontractors and
Vendors have been paid. Contractor shall provide such certificates
simultaneously with each application for payment.
(d) Contractor hereby subordinates any Liens to which it may be
entitled under Applicable Law or under the provisions of this Agreement to
any Lien granted in favor of the Financing Parties, whether such Lien in
favor of Financing Parties is created, attached or perfected prior to or
after the Lien in favor of Contractor. In addition, Contractor shall
submit proof satisfactory to Owner that it has included in each contract
entered into by it with a Subcontractor or Vendor a requirement that any
Lien to which such Subcontractor or Vendor may be entitled to thereunder or
by Applicable Law shall be subordinate and inferior to any Lien granted in
favor of the Financing Parties, whether such Lien in favor of Financing
Parties is created, attached or perfected prior to or after the Lien in
favor of such Subcontractor or Vendor.
(e) In the event of Owner's default under this Agreement, the
Financing Parties shall have the right to cure Owner's default and, in such
event, Contractor's duties and obligations under this Agreement shall be
unaffected. In that regard, the Financing Parties shall have (i) thirty
(30) days from the date notice of default is delivered to the Financing
Parties to cure such default if such default is the failure to pay amounts
to Contractor which are due and payable under the Contract or (ii) not less
than forty-five (45) days to cure such default if the breach or default
cannot be cured by the payment of money to Contractor so long as the
Financing Parties or their designee shall have commenced to cure the
default within such forty-five (45) day period and thereafter diligently
pursues such cure to completion and continues to perform any monetary
obligations under the Contract and all other obligations under the Contract
are performed by Owner or the Financing Parties. If possession of the
Project is necessary to cure such breach or default, and the Financing
Parties declare Owner in default and commence foreclosure proceedings, the
Financing Parties will be allowed a reasonable period to complete such
proceedings. If the Financing Parties are prohibited by any court order or
proceedings from curing the default or from commencing or prosecuting
foreclosure proceedings, the foregoing time periods shall be extended by
the period of such prohibition. Contractor further agrees to perform its
obligations hereunder for the benefit of the Financing Parties in the event
of Owner's default under this Agreement or under the Financing Documents,
provided that the Financing Parties (or its assignee) shall have cured all
defaults of Owner's obligations hereunder and shall have paid all amounts
then due, including costs to cure. In such event, the Financing Parties
(or its assignee) shall have the rights and obligations of Owner under this
Agreement; provided the Financing Parties shall have no personal liability
to Contractor for the performance of such obligations, and the sole
recourse of Contractor in seeking the enforcement of such obligations shall
be to such parties' interest in the Project.
ARTICLE VIII
TITLE, RISK OF LOSS AND POSSESSION
Section 8.01. Clear Title. Contractor warrants and guarantees that
legal title to and the ownership of the Work including, without limitation,
all Equipment, intellectual property (i.e. patents, licenses, methods,
processes, trade secrets, know how, etc.), Drawings, Final Plans, operation
and maintenance manuals and any operating spare parts purchased by
Contractor on behalf of Owner at Owner's request in connection with the
construction, operation and maintenance of each Phase shall pass to Owner,
free and clear of any and all Liens on the earlier of the Commercial
Operation Date for each Phase or upon the termination of this Agreement.
Section 8.02. Risk of Loss. For each Phase, from date hereof until
the Commercial Operation Date for such Phase, Contractor hereby assumes the
risk of loss for the Phase and the Work related thereto including: (a) any
Equipment for such Phase whether on or off the Job Site, (b) all other Work
for such Phase completed on or off the Job Site and (c) all Work for such
Phase in progress. All Equipment not yet incorporated into the Plant shall
be stored in secured areas. Contractor shall bear the responsibility of
preserving, safeguarding, and maintaining such Equipment and any other
completed Work and Work in progress (including spare parts provided by
Owner). If any loss, damage, theft or destruction occurs to the Phase or
Work related thereto, on or off the Job Site for which Contractor has so
assumed the risk of loss, Contractor shall, at its cost, promptly repair or
replace the property affected thereby, provided however, Contractor shall
not be required to repair or replace, unless Owner makes the proceeds of
insurance available. Following the transfer of clear title to Owner as
stated above in Section 8.01, risk of loss for the Phase and related Work
shall pass to Owner (excluding the Contractor Equipment and other items to
be removed by Contractor, which shall remain the responsibility of
Contractor). From and after the date of the transfer of the care, custody,
and control of the Facility or portion thereof (a) Owner shall assume all
risk of physical loss or damage thereto, and all responsibility for
compliance by the Plant or portion thereof, with applicable safety and
environmental laws, and all other applicable laws and (b) Owner shall, and
does hereby, release Contractor from, and Owner will and shall cause
insurers to waive Rights of Subrogation against Contractor and its vendors
and subcontractors for loss or damage to the Plant which may thereafter
occur; provided, however, Contractor shall continue to be responsible
through Final Acceptance for claims, physical loss or damage to the work to
the extent resulting from Contractor's negligent acts or omissions, and/or
failure to comply with contractual requirements.
Section 8.03. Possession of Phases Following Commercial Operation.
Unless Owner has earlier taken possession and control of the Plant and the
Work pursuant to the terms hereof, Owner shall take possession and control
of each Phase and the related Work on the Commercial Operation Date for
each Phase. Contractor shall thereafter use all reasonable efforts to
minimize interference with Owner's operation of such Phase while completing
the Work under this Agreement.

Rating Guide (a "Qualified Insurer").
Section 9.04. Certificates of Insurance. Contractor shall require all
insurers under the Contractor Insurance Policies to provide the Financing
Parties, Owner and such other interested Persons as may be designated by
Owner with certificates of insurance, in form and substance acceptable to the
Financing Parties and Owner, evidencing and describing the insurance policies
and endorsements maintained hereunder upon commencement of the Work, or upon

transmission.
Section 9.06. Subcontractors' Insurance. Before permitting any of
its Subcontractors to perform any Work at the Job Site, Contractor shall
obtain a certificate of insurance from each such Subcontractor evidencing
that such Subcontractor has obtained the insurance required of
Subcontractors by Contractor and in the case of Substantial Subcontractors,
as required by Owner. All policies of Subcontractors shall include a
waiver of any right of subrogation of the insurers thereunder against
Owner, the Financing Parties and Contractor, and any right of the insurers
to set-off or counterclaim, offset or any other deduction, whether by
attachment or otherwise, in respect of any liability or any such Person
insured under such policy. Policies provided by Substantial Subcontractor
shall be in amounts and upon conditions as are customarily and normally
provided in the power generation industry.
Section 9.07. Remedy on Failure to Insure. If Contractor shall fail
to obtain and keep in force the Contractor Insurance Policies, Owner may,
without limiting any other remedy it may have, obtain and keep in force any
such insurance and pay such premium or premiums as may be necessary for
that purpose and recover from Contractor whether by way of deduction,
offset or otherwise the cost of obtaining and maintaining such insurance.
Section 9.08. Management of Insurance Policies. Except as directed
by Owner, Contractor shall be responsible for managing and administering
all Contractor Insurance Policies, including the filing of all claims and
the taking of all necessary and proper steps to collect any proceeds on
behalf of the relevant insured Person. Contractor shall at all times keep
Owner informed of the filing and progress of any claim. If Contractor
shall fail to perform these responsibilities, Owner may take such action as
it determines appropriate under the circumstances. In the event Contractor
collects proceeds on behalf of other Persons, it shall ensure that these
are paid directly from the insurers to the relevant Person and, in the
event that it receives any such proceeds, it shall, unless otherwise
directed by Owner, pay such proceed to such Party forthwith and prior
thereto, hold the same in trust for the recipient.
Section 9.09. Owner Insurance Policies. Prior to the Initial Site
Mobilization by Contractor and continuing through the Final Acceptance
Date, Owner shall obtain and maintain in force an All Risk Installation and
Builder's Risk Insurance Policy (the "Builder's Risk Policy") in an amount
at least equal to the full replacement value of the Project. A certificate
of insurance evidencing the Builder's Risk Insurance coverage and, if
applicable, the Delay in Start-Up insurance shall be furnished to
Contractor prior to Initial Site Mobilization by Contractor. Contractor and
its Subcontractors shall be named as additional insureds thereunder only as
their respective interests may appear. The Builder's Risk Policy shall
contain the following terms: an amount equal to the full replacement value
of the Work for "all risks" of physical loss or damage except as
hereinafter provided, including coverage for earth movement, flood, boiler
and machinery, transit and off-site storage accident exposure, start-up and
testing coverage until the Final Acceptance Date, but excluding the
Contractor Equipment and personal property. The Builder's Risk Policy may
contain separate sub-limits and deductibles subject to insurance company
underwriting guidelines. The Builder's Risk Policy will be maintained in
accordance with terms currently available in the insurance market for the
construction of electric generating facilities. Subject to insurance
company underwriting and approval, Delay in Start-Up insurance shall be
provided and maintained by Owner in an amount covering a period of
indemnity equal to twelve (12) months. Such Delay in Start-Up insurance
shall only apply in the event of physical loss or damage to the Work caused
by an insured peril under the Builder's Risk Policy. In the event a loss
is sustained under the Builder's Risk Policy, such loss will be adjusted by
Owner and/or the Financing Parties with the insurance companies.
Contractor will assist the Owner and the Financing Parties in the
adjustment of losses. Contractor shall replace or repair any loss or
damage (so long as Contractor is compensated therefor from any proceeds
received as a result of such loss) and complete the Work in accordance with
this Agreement. The Owner and the Contractor agree to waive all rights of
recovery against each other for damages caused by fire and/or other perils
to the extent covered by the Builder's Risk Policy.
Section 9.10. Contractor's Assistance. Contractor shall cooperate
with Owner in obtaining and maintaining the insurance policies of Owner and
shall provide all Drawings, Final Plans, certificates and other information
that Owner or its insurers may reasonably require. Contractor shall with
all due diligence comply with the conditions of Owner's insurance polices
and all reasonable requirements of the insurers in connection with the
settlement of claims, the recovery of losses and the prevention of
accidents and shall bear at its own cost the consequences of any failure to
do so.
Section 9.11. No Limitation on Liability. Nothing in this Article IX
shall be deemed to limit Contractor's liability under this Agreement to the
insurance coverages required by this Article. Except for the coverage
limits of liability for insurance companies set forth in Section 9.01, no
limitation of liability provided to Contractor under this Agreement is
intended nor shall run to the benefit of any insurance company or in any
way prejudice, alter, diminish, abridge or reduce, in any respect, the
amount of proceeds of insurance otherwise payable to Owner or the Financing
Parties under coverage required to be carried by Contractor under this
Agreement, it being the intent of the Parties that the full amount of
insurance coverage bargained for be actually available notwithstanding any
limitation of liability contained in this Agreement, if any.
ARTICLE X
SYCHRONIZATION, TESTS AND FINAL ACCEPTANCE
Section 10.01. General.
(a) All start-up, synchronization, operation and testing conducted by
Contractor shall be in accordance with this Agreement, applicable
manufacturers' instructions and warranty requirements, Applicable Laws,
Applicable Permits, Prudent Utility Practices and any and all applicable
rules as agreed to by Owner and Contractor. Contractor shall provide Owner
with at least thirty (30) days advance written notice of the first test of
each Phase that involves delivering energy to the Grid. In addition, no
test of the Plant or any Phase that delivers electrical output shall be
conducted unless Contractor gives prior written notice thereof as provided
in the following paragraph (b). Owner, Financing Parties, Utility and the
Facilities Engineer and their respective authorized representatives shall
have the right to inspect the Work and to be present during the start-up,
synchronization, operation and testing of each Phase pursuant to this
Article X.
(b) Prior to performing any Test, Contractor shall deliver to Owner,
the Financing Parties and the Facilities Engineer a written notice of such
Test (a "Test Notice") and specifying a date for commencement of any or all
of the Tests for such Phase. Contractor shall coordinate the scheduling of
any Guaranteed Performance Test with the dispatch schedule for the Plant or
the Phase, as applicable, so as not to interfere with Owner's or its
Affiliates' obligations with respect thereto. Contractor shall deliver a
Test Notice at least ten (10) Business Days prior to the commencement of
any Test. If Owner, within five (5) Business Days after its receipt of
such Test Notice, delivers to Contractor a written notice (i) denying that
the prerequisites for performing such Test have been completed and (ii)
stating the facts upon which such reasonable denial is based, then upon
receipt of such notice, Contractor shall take such action as is appropriate
to remedy the conditions described in such notice from Owner. Following
any such remedial action, Contractor may deliver to Owner, the Financing
Parties and the Facilities Engineer a new Test Notice conforming to the
requirements of this paragraph (b), and the provisions of this paragraph
(b) shall apply with respect to such new Test Notice in the same manner as
they applied with respect to the original Test Notice. The foregoing
procedure shall be repeated as often as necessary until Owner no longer
rejects the Test Notice; provided, however, if the Contractor is required
to notify following receipt of Owner's written notice in which Owner denies
that the prerequisites for performing a task have been completed, such
renotification may be given within five (5) business days of such notice by
Owner, and Owner shall have three (3) business days following the receipt
of such resubmitted notice to file written objections above. Contractor
shall reschedule Tests as reasonably requested by Owner to accommodate the
schedules of Persons whom the Owner deems necessary to attend the Tests.
Contractor shall promptly notify each of Owner, the Financing Parties and
the Facilities Engineer of any proposed change in the schedule of Tests and
may not conduct any Test under such proposed changed schedule unless Owner,
the Financing Parties and the Facilities Engineer receive reasonable
advance notice of the actual date of commencement of such rescheduled Test.
Owner shall be responsible for notifying the Utility and any Person other
than the Utility, Financing Parties and the Facilities Engineer for
witnessing Tests.
Section 10.02. Synchronization. Together with the notice of the
Scheduled Synchronization Date, Contractor shall provide Owner and Utility
a start-up and test schedule for the applicable Phase and copies of all
manufacturers' specifications, schedules of protection schemes, and
protection relay settings. Contractor shall promptly give Owner and
Utility notice of any expected change in the Scheduled Synchronization Date
or other information provided with the notice as described above (or any
modifications thereto); provided that Contractor shall provide at least ten
(10) days prior written notice of the actual synchronization date. The
Contractor shall perform the synchronization procedures in accordance with
the Scope of Work and Utility's requirements. Utility and its authorized
representatives shall have the right to be present during the
synchronization.
Section 10.03. Minimum Performance Tests. After a Phase (a) has
achieved Mechanical Completion, as determined by Contractor and approved by
Owner, (b) has been synchronized with the Grid in accordance with the Scope
of Work and Utility's requirements, (c) is capable of being operated
safely, normally and continuously in accordance with the requirements of
this Agreement at all operating conditions and modes specified in the Scope
of Work (although minor portions of such Phase not essential to its safe
continuous and reliable operation may remain to be completed), and (d) is
ready for the Minimum Performance Tests to be performed in accordance with
this Agreement, Contractor shall conduct the Minimum Performance Tests for
such Phase in accordance with the terms of this Agreement, including the
Scope of Work, after complying with the notice provisions of Section
10.01(b). If a Phase fails all or any part of a Minimum Performance Test
as determined in accordance with the Scope of Work and Section 11.09(a),
Contractor shall take appropriate corrective action and the Minimum
Performance Test shall be performed again. If the Phase fails all or any
part of the retest, Contractor shall take appropriate corrective action and
the Minimum Performance Test shall be repeated. Subject to the terms and
conditions contained herein, so long as Contractor is paying when due
Schedule Liquidated Damages (if applicable), Contractor may repeat the
Minimum Performance Test as it determines necessary prior to termination of
this Agreement. Contractor shall provide a written report of the results
of each Minimum Performance Test to Owner, the Facilities Engineer and the
Financing Parties.
Section 10.04. Guaranteed Performance Tests.
(a) After each Phase has achieved the Minimum Performance Levels
necessary for Commercial Operation as determined pursuant to Section
11.09(a), and the Phase is capable of being operated safely, normally and
continuously in accordance with the requirements of this Agreement at all
operating levels specified in the Scope of Work (although minor portions of
such Phase not essential to its safe continuous and reliable operation may
remain to be completed), and after complying with the notice provisions of
Section 10.01(b), Contractor shall conduct the Guaranteed Performance Tests
for such Phase in accordance with the terms of this Agreement, including
the Scope of Work. If the Phase fails all or any part of a Guaranteed
Performance Test as determined in accordance with the Scope of Work and
Section 11.09(b), Contractor shall take appropriate corrective action and
the Guaranteed Performance Test shall be performed again. If the Phase
fails all or any part of the retest, Contractor shall take appropriate
corrective action and the Guaranteed Performance Test shall be repeated.
Subject to the terms and conditions contained herein, so long as Contractor
is paying when due Schedule Liquidated Damages (if applicable), Contractor
may repeat the Guaranteed Performance Test for a Phase as it determines
necessary until one hundred eighty (180) days after the Commercial
Operation Date for such Phase or the earlier termination of this Agreement.
Contractor shall provide a written report of the results of each Guaranteed
Performance Test to Owner, the Facilities Engineer and the Financing
Parties.
(b) If the results of additional Guaranteed Performance Tests
continue to demonstrate that the Plant fails to meet the Guaranteed
Performance Levels and all other requirements for Final Acceptance have
been met, at any time after the Phase II Guaranteed Commercial Operation
Date and prior to termination of this Agreement, the Contractor may, at its
discretion, submit a notice to Owner of Final Acceptance in accordance with
Section 10.07 and pay the applicable damages pursuant to Section 11.05.
Providing that Guaranteed Performance Tests demonstrate that the Plant
continues to achieve Minimum Performance Levels necessary for Commercial
Operation and for Final Acceptance as determined pursuant to this
Agreement, if Contractor elects to accept liquidated damages for certain
performance guarantees pursuant to Section 11.05 in lieu of achieving
Guaranteed Performance Levels, Contractor may submit proposed Final
Acceptance Certificate in accordance with Section 10.07 no later than 180
days after the Phase II Guaranteed Commercial Operation Date and pay the
applicable liquidated damages. The parties understand and agree that the
Contrator's obligations to achieve Guaranteed Performance Levels with
respect to emissions and noise (see Sections 11.04(c) and 11.04(d)) are
absolute obligations which must be achieved no later than 180 days after
the Phase II Guaranteed Commercial Operation Date.
Section 10.05. Punch List.
(a) During the Performance of the Work, Contractor shall maintain a
list setting forth parts of the Work which remain to be performed in order
to confirm that the Work fully complies with the terms of this Agreement.
Contractor shall promptly provide a copy of such list to Owner upon
request.
(b) No later than fourteen (14) days after the Phase I Commercial
Operation Date, Contractor shall prepare and submit to Owner a
comprehensive list (the "Punch List") of items to be completed for such
Phase to reach Final Acceptance. Contractor shall make such revisions to
the Punch List as and when requested by Owner from time to time; provided
that Contractor shall not be obligated to include any items on the Punch
List that directly relate to any Phase I Equipment for which Owner has
taken operational care, custody and control if such items were submitted by
Owner more than the later of (i) twenty-one (21) days after the Phase I
Commercial Operation Date or (ii) seven (7) days after receipt of the Punch
List from Contractor pursuant to this paragraph (b).
(c) No later than seven (7) days after the Phase II Commercial
Operation Date, Contractor shall submit to Owner a revised Punch List
including all items to be completed to reach Final Acceptance. Contractor
shall make such revisions to the Punch List as and when requested by Owner
from time to time; provided that Contractor shall not be obligated to
include any items on the Punch List that directly relate to any Phase II
Equipment for which Owner has taken operational care, custody and control
if such items were submitted more than the later of (i) fourteen (14) days
after the Phase II Commercial Operation Date or (ii) seven (7) days after
receipt of the Punch List from Contractor pursuant to this paragraph (c).
(d) Upon request of Owner, Contractor shall promptly estimate the
reasonable commercial value of all items on the punch list that have not
been completed. The Parties agree that with respect to punch list items
that remain uncompleted and which are preventing Final Acceptance, it may
be more expedient for Owner to complete such punch list items, as its
election and option. If the Parties are able to agree upon the commercial
value of all items on the punch list, and the Owner so elects, at its sole
discretion, the Owner may, in lieu of requiring the Contractor to complete
the punch list items, require the Contractor to pay to Owner an amount
equal to 150% of the commercial value of the remaining punch list items as
agreed upon by the Owner. Owner shall have the right to offset such amount
owed by Contractor against any amounts owed by Owner to Contractor at Final
Acceptance, or otherwise under this Agreement.
Section 10.06. Commercial Operation.
(a) After completing the Minimum Performance Tests in accordance with
Section 10.03, when the Contractor determines that all of the requirements
for Commercial Operation for a Phase have been completed, Contractor shall
provide written notice thereof to Owner, the Financing Parties and the
Facilities Engineer. Except as provided in Section 10.06(b), the date
specified by Contractor on which Phase I Commercial Operation or Phase II
Commercial Operation was achieved in its notice to Owner of Commercial
Operation shall be the "Phase I Commercial Operation Date" or the "Phase II
Commercial Operation Date", respectively.
(b) Within three (3) Business Days following receipt by Owner of such
notice of Commercial Operation, Owner shall notify Contractor in writing
whether or not Owner and the Facilities Engineer believe that Contractor
has fulfilled the requirements of Phase I Commercial Operation or Phase II
Commercial Operation, as applicable. If Owner and the Facilities Engineer
determine that Contractor has not fulfilled such requirements for
Commercial Operation, Owner shall specify in such notice to Contractor in
reasonable detail the reasons for determining that the requirements for
Commercial Operation have not been met. Contractor shall promptly act to
correct such deficiencies so as to achieve Commercial Operation for the
applicable Phase as soon as possible (and no later than by the applicable
Guaranteed Commercial Operation Date if such date has not already passed).
Following any such remedial action, Contractor shall deliver to Owner and
the Facilities Engineer a new notice of Commercial Operation and the
provisions of this Section 10.06(b) shall apply with respect to such new
Commercial Operation notice in the same manner as they applied to the
original Commercial Operation notice. The foregoing procedure shall be
repeated as often as necessary, so long as Contractor is paying when due
Schedule Liquidated Damages (if applicable), until the earlier of (i) Owner
and the Facilities Engineer no longer reject Contractor's Commercial
Operation notice and Owner provides its own notice to Contractor that
Commercial Operation has been achieved, or (ii) termination of this
Agreement. The date specified by Owner and the Facilities Engineer on
which the Phase I Commercial Operation or Phase II Commercial Operation, as
applicable, was achieved in its notice to Contractor of Commercial
Operation shall be the "Phase I Commercial Operation Date" or "Phase II
Commercial Operation Date", respectively.
(c) If Contractor fails to achieve Phase I Commercial Operation by
the Phase I Guaranteed Commercial Operation Date, and/or Phase II
Commercial Operation by the Phase II Guaranteed Commercial Operation Date,
Contractor shall pay to Owner the Schedule Liquidated Damages pursuant to
Article XI. Payment of such damages shall not relieve Contractor from its
obligations hereunder to achieve Commercial Operation for each Phase and
Final Acceptance.
Section 10.07. Final Acceptance of the Plant. After achieving
Commercial Operation for each Phase in accordance with Section 10.06, when
the Contractor determines that all of the requirements for Final Acceptance
have been completed (other than execution of the Final Acceptance
Certificate by Owner), or when the Contractor has elected to or is required
to pursuant to Section 10.04(b), Contractor shall submit a proposed Final
Acceptance Certificate, in substantially the form attached hereto as
Exhibit G, to Owner and the Facilities Engineer. As soon thereafter as
reasonably practicable, a team consisting of representatives of Owner, the
Financing Parties, the Facilities Engineer and Contractor shall make a
final inspection of the Plant. Within ten (10) Business Days following
such final inspection, Owner, with the consent of the Financing Parties,
shall notify Contractor in writing whether such Persons believe that
Contractor has fulfilled the requirements of this Agreement to reach Final
Acceptance (other than execution of the Final Acceptance Certificate by
Owner). If Owner and the Financing Parties determine that such
requirements have been fulfilled, Owner will execute the proposed Final
Acceptance Certificate. If Owner and the Financing Parties determine in
good faith that, notwithstanding Contractor's delivery of the proposed
Final Acceptance Certificate, the requirements for Final Acceptance have
not been fulfilled, then Owner shall deliver a written notice to such
effect to Contractor describing in reasonable detail the deficiencies noted
and corrective action recommended, including projected target dates for the
completion of such incomplete or remedial Work. Contractor shall promptly
act to correct any such deficiencies. The procedure set forth in this
Section 10.07(a) shall be repeated as necessary, so long as Contractor is
paying when due Schedule Liquidated Damages (if applicable), until the
earlier of (i) Owner and the Financing Parties no longer reject
Contractor's proposed Final Acceptance Certificate and Owner executes such
certificate or (ii) termination of this Agreement.
ARTICLE XI
CONTRACTOR GUARANTEES
Section 11.01. Completion Guarantee.
(a) Contractor hereby guarantees that Phase I Commercial Operation
will occur no later than the Phase I Guaranteed Commercial Operation Date,
and Phase II Commercial Operation will occur no later than the Phase II
Guaranteed Commercial Operation Date.
(b) In the event that Phase I Commercial Operation occurs after the
Phase I Guaranteed Commercial Operation Date but prior to December 1, 2000
or, Phase II Commercial Operation occurs after the Phase II Guaranteed
Commercial Operation Date and Contractor is able to achieve Commercial
Operation within one hundred fifty (150) days after the Phase II Guaranteed
Commercial Operation Date, Owner shall be relegated as its sole remedy to
the assessment of Schedule Liquidated Damages provided for in Section
11.02. Provided the Contractor has not otherwise materially breached the
Agreement, is paying the assessed Schedule Liquidated Damages, and schedule
progress appears to the Owner and Independent Engineer to be sufficient to
achieve Phase I Commercial Operation by December 1, 2000, and Phase II
Commercial Operation within one hundred fifty (150) days of the Phase II
Guaranteed Commercial Operation Date, the failure to achieve Commercial
Operation by the applicable Guaranteed Commercial Operation Date shall not
be considered an event of default under this Agreement.
(c) If and in the event the Contractor fails to achieve Phase I
Commercial Operation prior to December 1, 2000 or Phase II Commercial
Operation within one hundred fifty (150) days of the Phase II Guaranteed
Commercial Date, then, in that event, the Contractor shall be considered in
default, and may be terminated as provided for in Article XV of this
Agreement.
(d) If and in the event Phase I Commercial Operation has not occurred
by December 1, 2000, or Phase II Commercial Operation has not occurred
within one hundred fifty (150) days after the Phase II Guaranteed
Commercial Operation Date, and if in such event the Schedule Liquidated
Damages have not been exhausted, and Contractor is permitted to continue
performance, Owner's damage for delay will remain limited by liquidated
damages and those damages will be assessed on a day-by-day basis as before.
Section 11.02. Schedule Liquidated Damages.
(a) Owner and Contractor acknowledge and agree that any failure to
achieve Commercial Operation for each Phase by the applicable Guaranteed
Commercial Operation Date will directly cause substantial damage to Owner,
which damage cannot be ascertained with reasonable certainty. Accordingly,
if Contractor shall fail to achieve Commercial Operation for either Phase
by the applicable Guaranteed Commercial Operation Date, subject to Section
11.07(c), it shall pay to Owner, as liquidated damages, the following
amounts (collectively, the "Schedule Liquidated Damages"):
(i) for Phase I, an amount equal to [ ] for each day (or
portion thereof) that Phase I Commercial Operation is delayed beyond
the Phase I Guaranteed Commercial Operation Date, commencing with the
first day following the Phase I Guaranteed Commercial Operation Date
through and including the thirtieth (30th) day. After the thirtieth
(30th) day, Contractor will pay an amount equal to [ ] for each
day through and including the Phase I Commercial Operation Date; and
(ii) for Phase II, an amount equal to [ ] for each day (or
portion thereof) that Phase II Commercial Operation is delayed beyond
the Phase II Guaranteed Commercial Operation Date, commencing with the
first day following the Phase II Guaranteed Commercial Operation Date
through and including the sixtieth (60th) day. After the sixtieth
(60th) day, Contractor will pay an amount equal to [ ] for each
day through and including the Phase II Commercial Operation Date.
(b) It is understood and agreed between the Parties that the terms,
conditions and amounts fixed pursuant to this Article XI as liquidated
damages for failure to achieve Commercial Operation for each Phase by the
applicable Guaranteed Commercial Operation Date are reasonable, considering
the damages that Owner would sustain in such event, and that these amounts
are agreed upon and fixed as liquidated damages because of the difficulty
of ascertaining the exact amount of damages that would be sustained as a
result of delay in achieving Commercial Operation. Payment of such
liquidated damages shall not relieve Contractor of any of its obligations
hereunder. Furthermore, the remedy provided in this Section 11.02 is in
addition to the remedies provided in Section 11.05 and Articles XII, XV and
XVI and elsewhere in this Agreement. Notwithstanding anything contained
herein to the contrary, in the event that Contractor has not achieved
Commercial Operation for a Phase but has reached its maximum liability
hereunder for payment of Schedule Liquidated Damages, Contractor shall be
in breach of this Agreement.
Section 11.03. Early Completion Bonus. In the event Contractor
achieves Commercial Operation for either Phase prior to the applicable
Guaranteed Commercial Operation Date, then Owner shall pay to Contractor
the following amounts (collectively, the "Early Completion Bonus"):
(a) for Phase I, a bonus equal to the sum of [ ] for each day
(or portion thereof) that Phase I Commercial Operation is achieved prior to
the Phase I Guaranteed Commercial Operation Date, commencing with the first
day following the Phase I Commercial Operation Date through and including
the Phase I Guaranteed Commercial Operation Date; provided, however, that
the amount of the Early Completion Bonus payable by Owner for Phase I shall
not exceed [ ]; and
(b) for Phase II, a bonus equal to the sum of [ ] for each day
(or portion thereof) that Phase II Commercial Operation is achieved prior
to the Phase II Guaranteed Commercial Operation Date, commencing with the
first day following the Phase II Commercial Operation Date through and
including the Phase II Guaranteed Commercial Operation Date; provided,
however, that the amount of the Early Completion Bonus payable by Owner for
Phase II shall not exceed [ ].
No Early Completion Bonus shall be paid for early completion days occurring
prior to June 1, 2000 for Phase I and July 1, 2000 for Phase II.
Notwithstanding anything contained herein to the contrary, for purposes of
determining the Early Completion Bonus, the applicable Guaranteed
Commercial Operation Date shall not be extended or otherwise altered due to
any Force Majeure Events.
Section 11.04. Performance Guarantees in Excess of Minimum Performance
Levels.
(a) Plant Net Power Output Guarantee. Contractor guarantees to Owner
that the Net Power Output of the Plant will be equal to or greater than
1,000,000 kilowatts when corrected to the Guarantee Design Conditions
contained in the Scope of Work (the "Plant Net Power Output Guarantee").
The Plant Net Power Output is the sum of the Net Power Output of Phase I as
determined by the final Net Capacity and Heat Rate Test for Phase I when
corrected to the Guarantee Design Conditions and the Net Power Output of
Phase II as determined by the final Net Capacity and Heat Rate Tests for
Phase II when corrected to the Guarantee Design Conditions (the "Plant Net
Power Output").
(b) Plant Net Heat Rate Guarantee. Contractor guarantees to Owner
that the Net Heat Rate of the Plant will be equal to or less than 7,000 Btu
per KwH when firing design basis natural gas and when corrected to the
Guarantee Design Conditions (the "Plant Net Heat Rate Guarantee"). The
Plant Net Heat Rate is the sum of the Phase I Corrected Fuel Consumption,
and Phase II Corrected Fuel Consumption divided by the Plant Net Power
Output NKW (the "Plant Net Heat Rate").
(c) Emissions Guarantee. Contractor guarantees to Owner that the
emission of air contaminants into the atmosphere from the Plant shall be
equal to or less than the emissions limitations contained in the Applicable
Permits (as demonstrated through the use of the air quality sampling
criteria and the techniques referenced therein and excluding for purposes
of determining compliance with the Applicable Permits all variances and
waivers that may be applicable thereto) (the "Emissions Guarantee").
(d) Noise Guarantee. Contractor guarantees to Owner that the Plant
will function at a noise level that does not exceed the lower of (i) 75 dbA
at the Property Site boundary or (ii) that required by Applicable Law and
Applicable Permits (excluding for purposes of determining compliance with
the Applicable Permits all variances and waivers that may be applicable
thereto) under the modes of operation as described in the Scope of Work
(the "Noise Guarantee").
Section 11.05. Liquidated Damages for Certain Performance Guarantees.
(a) Subject to Section 11.07(c), the Parties agree that the
liquidated damages for failure to achieve the Guaranteed Performance Levels
specified in Sections 11.04(a) and 11.04(b) (as determined pursuant to
Section 11.09(b)) are as follows (collectively, the "Performance Liquidated
Damages"):
(i) Deficiency in Net Power Output. If the Plant Net Power
Output is less than ninety-nine percent (99%) of the Plant Net Power
Output Guarantee, Contractor shall pay to Owner an amount equal to
[ ] multiplied by the difference of ninety-nine (99%) of the Plant
Net Power Output Guarantee less the actual Plant Net Power Output
(each measured in kW).
(ii) Failure to Meet Guaranteed Net Heat Rate. If the Plant Net
Heat Rate is greater than one hundred two percent (102%) of the Plant
Net Heat Rate Guarantee, Contractor shall pay to Owner an amount equal
to [ ] multiplied by the difference of the Plant Net Heat Rate
less one hundred two percent (102%) of the Plant Net Heat Rate
Guarantee (each measured in Btu HHV per kilowatt hour).
(b) At any time within one hundred fifty (150) days following the
Phase II Commercial Operation Date, Contractor, at its option, may elect to
pay the liquidated damages set out herein in lieu of achieving the Plant
Net Power Output Guarantee and/or Plant Net Heat Rate Guarantee. The 11.04
Emissions Guarantee and Noise Guarantee are absolute requirements, no
liquidated damages are applicable thereto, and those guarantees must be met
before Final Acceptance. At no time between Commercial Operation and Final
Acceptance shall the performance of the Plant fall below Minimum
Performance Levels for reasons not due to Owner's operation of the Facility
as defined herein. If and in the event the Contractor does not elect to
utilize Performa Liquidated Damages, and fails to achieve the Plant Net
Power Output Guarantee or Plant Net Heat Rate Guarantee within one hundred
eighty (180) days following Phase II Commercial Operation, Contractor shall
be in default and Owner shall be entitled to recovery of all actual damages
occasioned thereby, and Owner shall be entitled to terminate this
Agreement.
Section 11.06. Performance Bonuses. Subject to the maximum amount of
bonuses payable as set forth below, the bonuses for the Contractor
achieving performance in excess of the Guaranteed Performance Levels
specified in Sections 11.04(a) and 11.04(b) (as determined pursuant to
Section 11.09(b)) are as follows (collectively, the "Performance Bonuses"):
(a) Net Power Output Bonus. If Contractor achieves a Plant Net Power
Output in excess of one hundred one percent (101%) of the Plant Net Power
Output Guarantee, Owner shall pay to Contractor an amount equal to [ ]
multiplied by the difference of the Plant Net Power Output of such Phase
less one hundred one percent (101%) of the Guaranteed Net Power Output
(each measured in kW).
(b) Net Heat Rate Bonus. If Contractor achieves a Plant Net Heat
Rate that is less than ninety-eight percent (98%) of the Guaranteed Net
Heat Rate, Owner shall pay to Contractor an amount equal to [ ]
multiplied by the difference of ninety-eight percent (98%) of the
Guaranteed Net Heat Rate less the Plant Net Heat Rate (each measured in Btu
HHV per kilowatt hour).
Notwithstanding anything contained herein to the contrary, the aggregate
amount of Performance Bonuses payable by Owner hereunder shall not exceed
[ ].
Section 11.07. Payment of Liquidated Damages.
(a) Schedule Liquidated Damages, if any, under this Article XI shall
accrue on a daily basis for each day (or portion thereof) of delay. Within
thirty (30) days after the end of each month during which Schedule
Liquidated Damages accrue under this Article XI, Owner shall provide
Contractor with a statement of the amount of Schedule Liquidated Damages
owed for such month. In addition, after the final Guaranteed Performance
Test performed demonstrates that the Plant has failed to achieve any or all
of the Guaranteed Performance Levels specified in Sections 11.04(a) and
11.04(b), Owner shall provide Contractor with a statement of the amount of
Performance Liquidated Damages owed. Contractor shall pay any Schedule
Liquidated Damages and Performance Liquidated Damages pursuant to this
Article XI within ten (10) days after receipt of such statement(s). Any
amounts not paid when due shall accrue interest from the due date until
paid at the Reference Rate. Owner shall have the right to offset any
amounts owing to Owner under this Article against Milestone Payments or
other amounts owing to Contractor. In addition, Owner in its sole
discretion may, but is not obligated to, collect Schedule Liquidated
Damages and/or Performance Liquidated Damages by drawing on the Letter of
Credit. Liquidated Damages are the exclusive remedies for delays if and in
the event the Plant ultimately achieves Commercial Operation before the
amount of Schedule Liquidated Damages are exhausted. Further, provided
that Contractor has timely paid Schedule Liquidated Damages, the failure to
achieve Commercial Operation prior to one hundred fifty (150) days from the
Guaranteed Commercial Operation Date shall not be considered a default and
Owner shall not be entitled to terminate and/or assess actual damages
during that time frame.
(b) Except as provided in Section 11.07(c), Contractor's obligation
to pay Schedule Liquidated Damages and Performance Liquidated Damages when
and as provided in this Article is an absolute and unconditional
obligation, and shall not be released, discharged, diminished, or in any
way affected by (i) any default by Owner in the performance or observance
of any of its obligations hereunder, (ii) the assignment by Owner of this
Agreement to the Financing Parties or any other Person, or (iii) any other
circumstances, happening, condition or event. Contractor shall pay such
liquidated damages without deduction, set-off, reduction or counterclaim.
(c) Notwithstanding anything contained herein to the contrary, the
aggregate amount of Schedule Liquidated Damages and Performance Liquidated
Damages payable by Contractor hereunder shall not exceed twenty-five
percent (25%) of the Separated Contract Price. Subject to the aggregate
amount of liquidated damages referenced above, schedule liquidated damages
shall be limited to 15% of the Separated Contract Price and Performance
Liquidated Damages shall be limited to 15% of the Separated Contract Price.
Section 11.08. Payment of Bonuses.
(a) The aggregate of any Early Completion Bonus and/or Performance Bonus
shall be payable to Contractor in two (2) interest-free (until due, owing
and unpaid) equal semi-annual payments out of "Disttributable Cash"
following Final Acceptance of the Plant. Any amounts not paid hereunder
due to the inadequacy of "Distributable Cash" shall be carried over for
payment (with interest thereon accruing at the Stipulated Interest Rate)
until the next succeeding payment date. It is understood that no equity
distributions may be made to any partner of the Owner until any due or past-
due Early Completion Bonus or Performance Bonus amount is paid.
(b) Contractor understands and agrees that the distributions of
Distributable Cash may be restricted by the Security Deposit Agreement.
Contractor also agrees that any default, breach, rejection or repudiation
by Owner of any obligation or provision contained in this Sections 11.03,
11.06 and 11.08 shall not be a default by Owner under this Agreement;
provided, however, that if Owner repudiates (a) its obligations to make
payments first to Contractor before any distributions to any other person,
or (b) to cause the Trustee to make payments to Contractor required by
Section 11.08(d) hereof, as to which, in both cases, Contractor shall have
a legal claim sounding in debt, but only against such Distributable Cash
held by Owner but not paid to Contractor when owed, and in no event shall
Contractor terminate this Agreement on account of any such repudiation. In
no event shall Contractor make any claim against or assert any lien on the
Facility or any other asset of Owner by reason of the matters set forth in
this Sections 11.03, 11.06 and 11.08. The obligations to pay Early
Completion and/or Performance Bonus shall be non-recourse to Owner except
to the extent Owner receives Distributable Cash, and then recourse shall be
limited to such Distributable Cash. Contractor agrees that it shall have
no right to institute any action or proceeding or otherwise take any action
against the Owner trustee with respect to this Sections 11.03, 11.06 and
11.08.
(c) For purposes of Sections 11.03, 11.06 and 11.08 "Distributable Cash"
shall mean (A) for any period, the amount, if any by which project revenues
for such period exceed the sum of (i) project expenses for such period,
plus (ii) contribution to all reserve fund accounts for the period, plus
(iii) any required fees, and (B) "Indenture Agreement" shall mean that
certain Indenture Agreement between the Owner and the Person named as
Trustee in the Recitals of the Indenture Agreement.
(d) For so long as the Indenture Agreement is in effect, Owner agrees to
promptly distribute to Contractor, on a semi-annual basis, to the extent of
funds available therefor, the Distributable Cash, if any, payable to
Contractor hereunder, as provided in this Section 11.08 and pursuant to the
terms of the Indenture Agreement, in all cases senior and prior to any
payments of Distributable Cash to any other person.
(e) If the Indenture Agreement shall be amended or terminated so that
cash is no longer distributed to Owner thereunder, but is distributed to Owner
free and clear of any lien pursuant to some other agreement, then
"Distributable Cash" shall mean such cash being distributed to Owner pursuant
to such other agreement.
(f) The provisions of Sections 11.03, 11.06 and 11.08 above represent the
entire agreement of the parties concerning the payment of an Early
Completion Bonus and Performance Bonus and supersede, and shall not be
modified by, any Change Order.
Section 11.09. Determination of Performance.
(a) Contractor's compliance with the Minimum Performance Levels for
purposes of achieving Commercial Operation shall be determined on the basis
of the Minimum Performance Tests conducted in accordance with Article X and
the results of such tests shall be conclusive for such purpose. During the
Minimum Performance Test, the Net Power Output and net heat rate of the
Phase shall be measured concurrently at the same point while the Phase is
operating in compliance with the Emissions Guarantee (including for this
purpose all waivers and variances permitted under Applicable Permits).
(b) Subject to the tolerances set forth below, Contractor's
compliance with the Guaranteed Performance Levels, or the extent of its
failure to comply therewith, for purposes of achieving Final Acceptance
shall be determined on the basis of the Guaranteed Performance Tests
conducted in accordance with Article X and the results of such tests shall
be conclusive for such purpose. The Guaranteed Performance Tests shall be
conducted for each Phase separately and the results thereof shall be
combined in order to determine overall Plant performance as more fully
described in the Scope of Work. The Net Power Output and Net Heat Rate of
a Phase shall be determined pursuant to the Net Capacity and Heat Rate Test
and shall be measured concurrently at the same point while the Phase is
operating in compliance with the Emissions Guarantee (excluding for this
purpose all waivers and variances permitted under Applicable Permits).
Tolerances with respect to the results of the Guaranteed Performance Tests
shall be plus or minus one percent (1%) for the Plant Net Power Output
Guarantee and plus or minus two percent (2%) for the Plant Net Heat Rate
Guarantee. In the event the applicable Guaranteed Performance Test
demonstrates results at or within such tolerance bands, no liquidated
damages or bonuses shall be applicable. In the event the applicable
Guaranteed Performance Test demonstrates results outside of the relevant
tolerance band, liquidated damages and bonuses, as applicable, shall be
calculated on a "net" basis by deducting the amount of such tolerance band
from the results. Compliance with the Emissions Guarantee and the Noise
Guarantee shall be determined pursuant to the Emissions Test and the Noise
Test, respectively. The Emissions Test for each Phase shall be performed
by the earlier of (a) sixty (60) days after the Commercial Operation Date
for such Phase or (b) one hundred eighty (180) days after first fire for
such Phase.
Section 11.10. Minimum Performance Levels. Notwithstanding anything
herein to the contrary, it is a requirement that the Plant achieve the
Guaranteed Performance Levels as determined pursuant to Section 11.09(b) no
later than one hundred eighty (180) days after the Commercial Operation
Date of each Phase. Provided that each phase maintains Minimum Performance
Levels, the Contractor shall have the option during the one hundred eighty
(180) day period provided above to pay liquidated damages in lieu of
Guaranteed Performance Levels as specified in Section 11.05. There are not
liquidated damages payable by the Contractor hereunder in lieu of achieving
the emissions guarantee and the noise guarantee for the Plant. The Parties
agree that the Plant can only be operated in compliance with all Applicable
Permits. Notwithstanding anything contained herein to the contrary, in the
event that a phase has achieved Commercial Operation and prior to Final
Acceptance, such phase is not capable of being operated in accordance with
all the Plant's operating procedures and all applicable permits and the
other requirements of this Agreement, and all operating conditions
specified in the Scope of Work, Contractor shall be in default of this
Agreement.
Section 11.11. Retainage. No later than the earlier of (a) the
Financial Closing Date or (b) the date on which Owner provides a Notice to
Proceed, Contractor shall, at its own expense, cause the LC Issuing Bank to
issue and maintain, by renewal or replacement, for the periods specified
herein irrevocable, unconditional, transferable, standby, revolving letters
of credit in favor of Owner meeting the requirements of this Section 11.11
and in form and substance acceptable to Owner (as shown on Exhibit U
herein) and the Financing Parties (individually and collectively, the
"Letter of Credit"). The Letter of Credit shall constitute security for
Contractor's obligations hereunder. No later than ten (10) days after the
date hereof, Contractor shall provide to Owner a written commitment, in
form and substance acceptable to Owner and the Financing Parties, from the
LC Issuing Bank that it will issue and maintain the Letter of Credit.
Owner may, in its sole discretion, assign the Letter of Credit and such
written commitment to any Financing Party, lending agency, trustee or their
assignees or designees without the consent of Contractor. All fees and
charges, including, without limitation, issuing, commitment and operation
fees and charges, relating to the Letter of Credit shall be borne by
Contractor. The Letter of Credit shall comply with and be subject to the
following terms and conditions:
(a) Upon issuance, the Letter of Credit shall have a face amount
equal to ten percent (10%) of the total payments made (or to be made) by
Owner to Contractor through the date of such issuance. On a quarterly
basis, Contractor shall amend the Letter of Credit to an amount not less
than ten percent (10%) of the Milestone Payments scheduled to be made
during the next calendar quarter. Contractor shall not be entitled to
receive payment absent evidence that such amendments have been made. After
both Phases have successfully completed the Guaranteed Performance Tests,
Contractor may reduce the face amount of the Letter of Credit to an amount
equal to five percent (5%) of the Separated Contract Price. Thirty (30)
days after Final Acceptance, Owner shall return the Letter of Credit to the
LC Issuing Bank with instructions for cancellation.
(b) Following three (3) days written notice to Contractor, Owner
shall have the right to draw upon the Letter of Credit by presenting to the
LC Issuing Bank a draw certificate pursuant to the Letter of Credit
attached hereto as Exhibit U. Owner may draw upon the Letter of Credit for
Schedule Liquidated Damages, Performance Liquidated Damages for payment of
unpaid suppliers and payments made to remove liens filed by Contractor's
subcontractors, any and all other amounts payable to Owner hereunder and
for any other purpose specified in the draw certificate. Within two (2)
Business Days after any drawdown by Owner, Contractor shall restore the
Letter of Credit to the amount Contractor is required to maintain pursuant
to the preceding paragraph (a) and shall provide Owner and the Financing
Parties with evidence of such restoration. The Letter of Credit shall
allow Owner to immediately draw up to the full amount then available for
drawing thereunder in the event of any delay or failure by Contractor to
restore the Letter of Credit as so required.
(c) Each Letter of Credit shall have a term of at least twelve (12)
months. At least thirty (30) days prior to the expiration of the Letter of
Credit then in effect, Contractor shall cause the LC Issuing Bank to renew
the Letter of Credit or issue a new Letter of Credit and deliver such
renewed or new Letter of Credit to Owner.
(d) Owner, at Owner's expense, shall have the right to require
Contractor to provide a Bond to pay liens or claims pursuant to Section
53.201 through 53.211 of The Texas Property Code.
Section 11.12. Parent Guaranty. Contractor is a North Carolina
general partnership composed of Fluor Xxxxxx, Illinois, Inc., a Delaware
corporation, and Duke Project Services, Inc., a North Carolina corporation.
The respective corporate parents are Fluor Xxxxxx, Inc., a California
corporation and Duke Capital Corp., a Delaware corporation. Prior to
Financial Closing, Contractor shall provide to Owner an irrevocable,
unconditional guarantee in substantially the form of Exhibit I, duly
executed by the parent companies of both general partners for the benefit
of Owner and the Financing Parties under terms and conditions acceptable to
Owner and the Financing Parties ("Parent Guarantee"). In order to provide
Owner and the Financing Parties with evidence of Contractor's and
Contractor Parent Companies' financial ability to complete the Plant,
Contractor agrees to comply with reasonable requests for financial
information. Anything to the contrary notwithstanding, the Parent
Guarantee shall require Contractor's Parent Company to pay the reasonable
cost and expenses, including attorneys' fees, incurred in collecting funds
from Contractor Parent Company in the event of a default by Contractor
hereunder, or Contractor Parent Company under the Parent Guarantee.

any action (including correction of Defects) may be taken by Owner or a
third party chosen by Owner, without giving prior notice to the Contractor,
and in the case of a Defect, the reasonable cost of correction shall be
paid by the Contractor. In the event such action is taken by Owner, the
Contractor shall be promptly notified within one Business Day after
correction efforts are implemented, and shall assist whenever and wherever
possible in making the necessary corrections.
Section 12.05. Vendors and Subcontractors. Contractor shall, for the
protection of Contractor and Owner, obtain from the Vendors and
Subcontractors such guarantees and warranties with respect to Work
performed and Equipment supplied, used and installed hereunder as are
reasonably obtainable, which guarantees and warranties shall equal or

earlier of the Commercial Operation Date for each Phase or termination of
this Agreement, Contractor shall deliver to Owner copies of all relevant
contracts providing for such guarantees and warranties.
Section 12.06. Assignment of Warranties. Except as provided in
Section 12.01(d) of this Agreement, upon the earlier of the expiration of
Contractor's express warranty or termination of this Agreement, Contractor
shall assign to Owner all warranties received by it from Subcontractors and
Vendor or otherwise obtained under Section 12.05 pertaining to such Phase
(or the Plant or Work in the event of termination of this Agreement). Such
assignment of warranties to Owner must also allow Owner to further assign
such warranties. However, in the event that Owner makes any warranty claim
against Contractor with respect to Equipment or services supplied in whole
or in part by any Subcontractor or Vendor, and Contractor fulfills its
obligations with respect to such claim by Owner, Contractor shall be
entitled to enforce for its own benefit any warranty given by such
Subcontractor or Vendor with respect to such Equipment and services.

ARTICLE XIV
FORCE MAJEURE AND OWNER CAUSED DELAY
Section 14.01. Definition of Force Majeure Event.
(a) As used herein, the term "Force Majeure Event" shall mean any
event or circumstance, or combination of events or circumstances, that
arise after the date hereof, are beyond the reasonable control of the Party
claiming the Force Majeure Event, are unavoidable or could not be prevented
or overcome by the reasonable efforts and due diligence of the Party
claiming the Force Majeure Event and has an impact which will actually,
demonstrably, adversely and materially affect Contractor's ability to
complete one or more Milestones by the required date and performance of its
obligations in accordance with the terms of this Agreement. Without
limiting the generality of the foregoing, events that may give rise to a
Force Majeure Event include, without limitation, acts of God, natural
disasters, fires, earthquakes, lightning, floods, storms, civil
disturbances, riots, war, strikes, lockouts or other labor disputes (except
as set forth below), and the action of or failure to act on the part of any
Government Authority having or asserting jurisdiction that is binding upon
the Parties and has been opposed by all reasonable means. For the
avoidance of doubt, the term "Force Majeure Event" does not include,
without limitation, events that affect the cost or availability of
equipment, labor, materials or supplies, or strikes, lockouts or other
labor disputes with respect to the Labor of the Party (or its
Subcontractors and Vendors, as applicable) desiring to claim a Force
Majeure Event.
(b) Contractor has included ordinary lost days due to adverse weather
in its agreement to perform within the times set forth herein and thus
Contractor shall not be entitled to an extension of the time as a result of
weather conditions normally experienced in the geographic area. Only when
the number of days lost or adverse weather exceeds the number usually
encountered in the geographic area for any given month (as reported by the
National Weather Service or some other agency) will time be extended by
the excess.
Section 14.02. Notice of Force Majeure Event. The Party claiming a
Force Majeure Event shall within five (5) Business Days after it knows or
should have known of the occurrence of the Force Majeure Event (or in any
event, no later than sixty (60) days after the commencement of the Force
Majeure Event), give the other Party written notice describing the details
of the cause and nature of the Force Majeure Event, the anticipated length
of delay due to the Force Majeure Event and any other affect on the Party's
performance of its obligations hereunder; provided that if the Force
Majeure Event results in a breakdown of communications rendering it not
reasonably practicable to give notice within the applicable time limit
specified herein, then the Party claiming a Force Majeure Event shall give
such notice as soon as reasonably practicable after the reinstatement of
communications, but no later than five (5) Business Days after such
reinstatement. Within fifteen (15) days after initial notification, such
Party shall provide sufficient proof of the occurrence and duration of such
Force Majeure Event to the other Party and shall thereafter provide the
other Party with periodic supplemental updates to reflect any change in
information given to the other Party as often as requested by the other
Party. The Party claiming the Force Majeure Event shall give notice to the
other Party of (a) the cessation of the relevant Force Majeure Event and
(b) the cessation of the effects of such Force Majeure Event on the
performance by it of its obligations under this Agreement as soon as
practicable after becoming aware of each of (a) and (b) above.
Section 14.03. Delay from Force Majeure Event. So long as the
conditions set forth in this Section 14.03 are satisfied and subject to
Section 14.07, neither Party shall be responsible or liable for or deemed
in breach of this Agreement because of any failure or delay in complying
with its obligations under or pursuant to this Agreement to the extent that
such failure has been caused, or contributed to, by one or more Force
Majeure Events or its effects or by any combination thereof, and in such
event:
(a) except as otherwise provided herein, the performance by the Party
claiming the Force Majeure Event of its obligations hereunder shall be
suspended, and in the event that such Party is required to start or
complete an action during a specific period of time, such start date or
period for completion shall be extended, on the condition that: (i) such
suspension of performance and extension of time shall be of no greater
scope and of no longer duration than is required by the effects of the
Force Majeure Event; (ii) the Party claiming the Force Majeure Event
complies with Section 14.02; and (iii) the Party claiming the Force Majeure
Event continually uses commercially reasonable efforts to alleviate and
mitigate the cause and effect of the Force Majeure Event and remedy its
inability to perform;
(b) except as otherwise provided herein, the performance by the Party
not claiming the Force Majeure Event of its obligations hereunder shall be
suspended, and in the event that such Party is required to start or
complete an action during a specific period of time, such start date or
period for completion shall be extended; provided that such suspension of
performance and extension of time shall be of no greater scope and of no
longer duration than is required by any suspension of performance or
extension of time pursuant to the preceding clause (a) or other effects of
the Force Majeure Event; and
(c) in the event Contractor desires to claim a Force Majeure Event,
it must submit a request for Changes pursuant to Section 6.02(b), and
Contractor shall only be entitled to suspension of performance or extension
of time (including an extension of any Guaranteed Commercial Operation
Date) with respect thereto to the extent agreed upon by both Parties
pursuant to a Change Order in accordance with the principles of Section
14.03 and 6.02(b). Notwithstanding the above, if and in the event a
particular Force Majeure Event extends for a period of time exceeding
thirty (30) days, the Contractor shall be entitled to a Change Order
compensating Contractor for demonstrated reasonable extended job site
overhead costs, including but not limited to, idle equipment costs,
incurred by reason of such delay.
Section 14.04. Definition of Owner Caused Delay. As used herein, the
term "Owner Caused Delay" shall mean a delay that will actually,
demonstrably, adversely, and materially affect the critical path of the
Project. Such delay must be caused directly and solely as a result of
Owner's failure to perform its obligations hereunder.
Section 14.05. Notice of Owner Caused Delay. In the event Contractor
desires to claim an Owner Caused Delay, Contractor shall within five (5)
Business Days after it knows or should have known of the occurrence of the
Owner Caused Delay, give Owner written notice describing the details of the
Owner Caused Delay, the anticipated length of delay due to the Owner Caused
Delay and any other affect on Contractor's performance of its obligations
hereunder. Within fifteen (15) days after initial notification, Contractor
shall provide sufficient proof of the occurrence and duration of such Owner
Caused Delay to Owner and shall thereafter provide Owner with periodic
supplemental updates to reflect any change in information given to Owner as
often as requested by Owner.
Section 14.06. Delay from Owner Caused Delay. So long as the
conditions set forth in this Section 14.06 are satisfied and subject to
Section 14.07, Contractor shall not be responsible or liable for or deemed
in breach of this Agreement because of any failure or delay in completing
the Work in accordance with the Project Schedule or achieving Commercial
Operation by the Guaranteed Commercial Operation Date to the extent that
such failure has been caused by one or more Owner Caused Delays, and in
such event, except as otherwise provided herein, the start date or period
for completion of any portion of the Work shall be extended, on the
condition that: (i) such suspension of performance and extension of time
shall be of no greater scope and of no longer duration than is required by
the effects of the Owner Caused Delay; (ii) Contractor complies with
Section 14.05; and (iii) Contractor provides all assistance reasonably
requested by Owner for the elimination or mitigation of the Owner Caused
Delay. In the event Contractor desires to claim an Owner Caused Delay, it
must submit a request for Changes pursuant to Section 6.02(b), and
Contractor shall be entitled to suspension of performance or extension of
time (including an extension of any Guaranteed Commercial Operation Date)
together with demonstrated reasonable extended Job Site overhead costs,
including but not limited to, idle equipment costs, incurred by reason of
such delay to the extent agreed upon by both Parties pursuant to a Change
Order in accordance with the principles of Sections 14.03 and 6.02(b).
Section 14.07. Performance Not Excused. The payment of money owed
shall not be excused because of a Force Majeure Event or Owner Caused
Delay. In addition, a Party shall not be excused under this Article from
timely performance of its obligations hereunder to the extent that the
claimed Force Majeure Event or Owner Caused Delay was caused by any
negligent or intentional acts, errors, or omissions, or for any breach or
default of this Agreement by such Party. Furthermore, no suspension of
performance or extension of time shall relieve the Party benefiting
therefrom from any liability for any breach of the obligations that were
suspended or failure to comply with the time period that was extended to
the extent such breach or failure occurred prior to the occurrence of the
applicable Force Majeure Event or Owner Caused Delay. Notwithstanding
anything contained herein to the contrary, Contractor shall not be entitled
to receive any reimbursement or compensation for demobilization and/or
remobilization required as a result of any Force Majeure Event.

Section 15.03. Termination by Owner for Convenience. Owner may
terminate this Agreement at any time for any reason in its sole discretion
by giving written notice thereof to Contractor, which termination shall be

Payment Table for completed Milestones and accordance with the Cost Plus
Formula for partially completed Milestones. Contractor shall document the
costs claimed under clauses (b), (c), (d) and (e) above to Owner's
satisfaction and shall supply Owner with copies of the Subcontractor and
Vendor invoices and other receipts covering amounts claimed under such
clauses. Contractor shall submit an invoice to Owner for the Termination
Payment with the supporting information and documents referred to above,
and Owner shall pay such invoice within thirty (30) days after its receipt
of same unless it disputes any portion thereof, in which event Owner shall
only pay the undisputed portion of the Termination Payment within such
thirty (30) day period and the dispute over the remainder of the claimed
Termination Payment may be resolved pursuant to Article XVII. Contractor
shall utilize reasonable commercial efforts to include termination for
convenience provision with terms similar to the foregoing in all
subcontracts, contracts and purchase orders.
Section 15.04. Suspension by Owner for Convenience. Owner may suspend
all or a portion of the Work to be performed under this Agreement at any
time for any reason in its sole discretion by giving written notice thereof
to Contractor. Upon receiving any such notice of suspension, unless the

notice; (c) promptly make every reasonable effort to obtain suspension,
with terms satisfactory to Owner, of all orders, subcontracts and rental
agreements to the extent they relate to performance of suspended Work; (d)
continue to protect and maintain the Work performed, including those
portions on which Work has been suspended; and (e) take any other
reasonable steps to minimize costs and expenses associated with such
suspension. As full compensation for any suspension under this Section,
Contractor will be reimbursed by Owner for the following costs, reasonably
incurred, without duplication of any item, to the extent that such costs
directly result from such suspension of the Work and to the extent that
they do not reflect reimbursement for Contractor's, Vendors' or
Subcontractors' anticipated profit from unperformed work: (a) a standby
charge, sufficient to compensate Contractor for keeping, to the extent
required in the suspension notice, its organization and the Contractor
Equipment committed to the Work on a standby basis, as agreed to by Owner
and Contractor; (b) all necessary and reasonable costs incurred in
connection with demobilization and remobilization of Contractor's facility
and Labor and the Contractor Equipment; and (c) an equitable amount to
reimburse Contractor for the cost of receiving, maintaining and protecting
that portion of Work upon which performance has been suspended, as agreed
to by Owner and Contractor. Upon delivery of notice by Owner to Contractor
to resume suspended Work, Contractor shall immediately resume performance
under this Agreement to the extent required in the notice. If Contractor
desires to request a Change Order as a result of a suspension of Work under
this Section, it must, within fourteen (14) days after receipt of notice to
resume the suspended Work, submit to Owner a request for Changes in
accordance with Article VI, which request shall be accompanied by
sufficient documentation setting forth the schedule impact and monetary
extent of such claim in sufficient detail to permit thorough analysis by
Owner; provided that if such information is not available within such
fourteen (14) day period, Contractor shall notify Owner of such within such
fourteen (14) day period and provide an expected date (which shall be as
soon as reasonably practicable) for providing such information. If
Contractor does not submit a request for Changes within such fourteen (14)
day period and provide the information regarding schedule and monetary
impact as required above within such fourteen (14) day period (or by the
expected date if not possible during such fourteen (14) day period),
Contractor shall not be entitled to any additional consideration or other
amendments hereto and shall be deemed to have waived all claims and offsets
against Owner as a result of the suspension of Work. Contractor shall
permit access by Owner to pertinent records for purposes of reviewing the
claims by Contractor of schedule and monetary impact. No adjustment to the
Guaranteed Commercial Operation Dates, Separated Contract Price or other
terms herein shall be made for any suspension of Work under this Section to
the extent that performance would have been suspended, delayed or
interrupted as a result of any Force Majeure Event or Contractor's
noncompliance with the requirements of this Agreement. Contractor shall
use reasonable commercial efforts to include a suspension for convenience
provision with terms similar to the foregoing in all subcontracts and
purchase orders.
Section 15.05. Termination Due To Force Majeure Event. If a Force
Majeure Event has occurred and continues for a period of at least three
hundred and sixty-five (365) days, then, notwithstanding that the Parties
may by reason thereof have been granted an extension of required dates,
either Party may deliver a written notice to the other Party stating its
intention to terminate this Agreement. If at the expiration of thirty (30)
days after the other Party's receipt of such notice, the Force Majeure
Event is continuing, this Agreement shall terminate immediately. In the
event of such termination, Contractor shall be entitled to receive (a)
payments for Work (other than Prefunding Work) completed prior to such
termination for which Contractor has not previously been paid and (b)
payments for Prefunding Work, if any, due pursuant to Section 7.02. The
amount of consideration for such completed Work (other than Prefunding
Work) shall be determined in accordance with the Milestone Payment Table
for completed Milestones and the Cost Plus Formula for any partially
completed Milestones. Each Party shall bear its own costs and expenses in
connection with a termination of this Agreement pursuant to this Section.
Section 15.06. Termination by Contractor. Contractor may terminate
this Agreement upon the following terms and conditions:
(a) In the event that Owner fails to make any payment of amounts due
to Contractor hereunder by the date such payment becomes due (other than
payment of amounts disputed by Owner), Contractor may give written notice
thereof to Owner. If the amount due, plus any interest due thereon, is not
paid within thirty (30) days after the date of Owner's receipt of such
notice from Contractor, then Contractor shall have, at its option, the
right to suspend its performance of the Work. If Contractor so suspends
performance of the Work hereunder, it shall immediately resume performance
of the Work upon receipt of payment of the amounts due (other than disputed
amounts). At any time during a suspension of Work by Contractor under this
paragraph (a), Contractor may give written notice to Owner of its intent to
terminate this Agreement. If all amounts due (other than disputed amounts)
are not paid by Owner within thirty (30) days after Owner's receipt of such
notice from Contractor, this Agreement shall terminate immediately. In the
event of such termination, Contractor shall be entitled to a Termination
Payment in accordance with the terms of Section 15.03.
(b) If after the Financial Closing Date, the duration of suspension
of Work by Owner pursuant to Section 15.04 and Owner Caused Delays exceed
two hundred seventy (270) days, Contractor may give written notice to Owner
of its intention to terminate this Agreement. If at the expiration of
fifteen (15) days after Owner's receipt of such notice, Owner has not
provided Contractor with a notice to resume the suspended Work or the Owner
Caused Delay is continuing, as the case may be, this Agreement shall
terminate immediately. In the event of such termination, Contractor shall
be entitled to receive compensation for Work completed prior to such
termination for which Contractor has not previously been paid. The amount
of consideration for such completed Work shall be determined in accordance
with the Milestone Payment Table for completed Milestones and the
Contractor's Rate Schedule Exhibit K, for any partially completed
Milestones. Contractor shall bear all costs and expenses in connection
with a termination of this Agreement pursuant to this paragraph (b).
Section 15.07. Continuing Obligations and Remedies During Event
of Default. In the event of the occurrence of any default hereunder (a)
neither Party shall be relieved of any of its liabilities or obligations
hereunder, unless and until such liabilities and obligations are terminated
in accordance with the provisions hereof, and (b) each Party shall have the
right to pursue any right or remedy available to it, hereunder.

Owner in preparing an inventory of all Equipment in use or in storage at
the Job Site; and (g) Contractor shall take such other action as required
hereunder upon termination of this Agreement.

this Agreement pursuant to this Article XV, the rights and obligations of
the Parties hereunder shall terminate, except for (a) rights and
obligations accrued as of the date of termination, (b) rights and

Material or rendered removal or remediation of Pre-Existing Hazardous
Material more costly; and
(c) claims arising out of Contractor's use of Owner supplied
specification for the gas and steam turbine generators and ancillary
equipment.
Section 16.03. Conditions of Indemnification. The respective rights
and obligations of the Parties and the other indemnitees under this Article
XVI with respect to claims resulting from the assertion of liability by
third parties shall be subject to the following terms and conditions:
(a) Notice of Proceedings. Within fourteen (14) days (or such
earlier time as might be required to avoid prejudicing the indemnifying
Party's position) after receipt of notice of commencement of any action
evidenced by service of process or other legal pleading, the Person
claiming to be indemnified under the terms of this Section (the
"indemnified Person") shall give the Party from which indemnification is
sought (the "indemnifying Party") written notice thereof, together with a
copy of such claim, process or other legal pleading. Failure of the
indemnified Person to give such notice will not reduce or relieve the
indemnifying Party of liability hereunder unless and to the extent that the
indemnifying Party was precluded from defending such claim, action, suit or
proceeding as a result of the failure of the indemnified Person to give
such notice. In any event, the failure to so notify shall not relieve the
indemnifying Party from any liability that it may have to the indemnifying
Person otherwise than under this Article XVI.
(b) Conduct of Proceedings. Each Party and each other indemnitee
shall have the right, but not the obligation, to contest, defend and
litigate any claim, action, suit or proceeding by any third party alleged
or asserted against it arising out of any matter in respect of which it is
entitled to be indemnified hereunder and the reasonable costs and expenses
thereof (including reasonable attorneys fees and expert witness fees)
shall be subject to the said indemnity; provided that the indemnifying
Party shall be entitled, at its option, to assume and control the defense
of such claim, action, suit or proceeding at its expense upon its giving
written notice thereof to the indemnified Person. The indemnified Person
shall provide reasonable assistance to the indemnifying Party, at the
indemnifying Party's expense, in connection with such claim, action, suit
or proceeding. Upon such assumption, the indemnifying Party shall
reimburse the indemnified Person for the reasonable costs and expenses
previously incurred by it prior to the assumption of such defense by the
indemnifying Party. The indemnifying Party shall keep the indemnified
Person informed as to the status and progress of such claim, action, suit
or proceeding. Except as set forth in paragraph (c) below, in the event
the indemnifying Party assumes the control of the defense, the indemnifying
Party will not be liable to the indemnified Person under this Article for
any legal fees or expenses subsequently incurred by the indemnified Person
in connection with such defense. The indemnifying Party shall control the
settlement of all claims over which it has assumed the defense; provided,
however, that the indemnifying Party shall not agree to or conclude any
settlement that affects the indemnified Person without the prior written
approval of the indemnified Person, (whose said approval shall not be
unreasonably withheld).
(c) Representation. In the event the indemnifying Party assumes
control of the defense, the indemnified Person shall have the right to
employ its own counsel and such counsel may participate in such claim,
action, suit or proceeding, but the fees and expenses of such counsel shall
be at the expense of such indemnified Person, when and as incurred, unless:
(i) the employment of counsel by such indemnified Person has been
authorized in writing by the indemnifying Party; (ii) the indemnified
Person shall have reasonably concluded that there may be a conflict of
interest between the indemnifying Party and the indemnified Person in the
conduct of the defense of such action; or (iii) the indemnified Person
shall have reasonably concluded and specifically notified the indemnifying
Party either that there may be specific defense available to it which are
different from or additional to those available to the indemnifying Party.
If any of the preceding clauses (i) through (iii) shall be applicable, then
counsel for the indemnified Person shall have the right to direct the
defense of such claim, action, suit or proceeding on behalf of the
indemnified Person and the reasonable fees and expenses of such counsel
shall be reimbursed by the indemnifying Party.
Section 16.04. Contributory Negligence. If, due to the joint,
concurring, comparative or contributory fault, negligence or willful
misconduct of the Parties which gives rise to Damages for which the Parties
are entitled to indemnification under this Article, then such Damages shall
be allocated between the Parties in proportion to their respective degrees
of fault, negligence or willful misconduct contributing to such Damages.
Section 16.05. Remedies Not Exclusive. The rights of indemnity shall
not be exclusive with respect to any other right or remedy provided for in
this Agreement, either in law or equity.
Section 16.06. Tax Effect of Indemnification. Notwithstanding any
term or provision of this Agreement to the contrary, any indemnity payments
owned by a Party shall be reduced by any tax benefits to the indemnified
Person and increased by any tax detriments to the indemnified Person
resulting from such indemnity payment.
Section 16.07. Survival of Indemnification. The indemnification
provisions of this Article shall survive the Final Acceptance Date and the
termination of this Agreement.
ARTICLE XVII
DISPUTE RESOLUTION
Section 17.01. Friendly Consultation. In the event of any dispute,
controversy or claim between the Parties arising out of or relating to this
Agreement, or the breach, termination or invalidity thereof (collectively,
a "Dispute"), the Parties shall attempt in the first instance to resolve
such Dispute through friendly consultations between the Parties. If such
consultations do not result in a resolution of the Dispute within thirty
(30) days, then the Dispute may be submitted by either Party to binding
arbitration pursuant to the terms of Section 17.02, irrespective of the
magnitude thereof, the amount in dispute or whether such Dispute would
otherwise be considered justifiable or ripe for resolution by any court or
arbitral tribunal, by giving written notice thereof to the other Party;
provided, however that in no event shall a Party have the right to submit
the Dispute to arbitration if the institution of legal or equitable
proceedings based on such Dispute would be barred by any applicable statute
of limitations. The Parties agree to attempt to resolve all Disputes
arising hereunder promptly, equitably and in a good faith manner. The
Parties further agree to provide each other with reasonable access during
normal business hours to any and all non-privileged records, information
and data pertaining to such Dispute.
Section 17.02. Arbitration.
(a) Except as otherwise provided in Section 17.01 and Owner's
injunctive relief in accordance with Section 18.04, any Dispute shall be
settled exclusively and finally by binding arbitration in accordance with
the provisions of this Section. This Agreement and the rights and
obligations of the Parties shall remain in full force and effect pending
the award in such arbitration proceeding, which award shall determine
whether and when termination of this Agreement, if relevant, shall become
effective.
(b) The arbitration shall be conducted in accordance with the
Construction Industry Arbitration Rules of the American Arbitration
Association, except as such rules conflict with the provisions of this
Article XVII, in which event the provisions of this Article XVII shall
prevail.
(c) Any Party electing to arbitrate a Dispute shall designate its
nomination for an arbitrator in its notice to the other Party electing to
submit the Dispute to arbitration. The Party receiving such notice shall,
within ten (10) Business Days thereafter, by return written notice, state
whether it will accept such nomination, or decline to accept it and
designate its nomination for an arbitrator. One arbitrator shall control
the proceedings if such nomination of an arbitrator is accepted or if the
receiving Party fails to nominate an arbitrator within the required ten
(10) day period. If the receiving Party timely nominates an arbitrator,
the arbitral tribunal shall consist of three (3) arbitrators, with the two
selected arbitrators choosing a third. In the event the arbitrators fail
to appoint the third arbitrator within thirty (30) days after they have
accepted their appointment, the third arbitrator shall be appointed by the
American Arbitration Association. No arbitrator shall be a former or
present Affiliate, employee, director, officer, agent, representative,
advisor, consultant or counsel of either Party.
(d) The place of arbitration shall be Dallas, Texas, unless in any
particular case the Parties agree upon a different venue. Within ten (10)
days after the selection of the arbitrator(s), the arbitrator(s) shall
convene by teleconference with the Parties and establish the time and
procedure for arbitration; provided, however, that the arbitrator(s) must
use their best efforts to establish the arbitration as soon as practicable,
but not later than twenty-one (21) days after such teleconference.
(e) The arbitrator(s) shall not have the authority to amend or modify
the terms of this Agreement. Any decision or award of the arbitrator(s)
pursuant to this Section 17.02 shall be final and binding upon the Parties.
The Parties agree that the arbitral award may be enforced against the
Parties to the arbitration proceeding or their assets wherever they may be
found and that a judgment upon the arbitral award may be entered in any
court having competent jurisdiction thereof. The Parties expressly submit
to the jurisdiction of any such court. The Parties hereby waive, to the
extent permitted by law, any rights to appeal or to review of such award by
any court or tribunal. The prevailing party in any arbitration proceeding
shall be entitled to recovery costs, and reasonable and necessary
attorney's fees.
(f) Interest at the Reference Rate from the date the amount in
dispute was first due until the date of payment shall be due and payable to
the Party in receipt of an arbitration award.
(g) The rights and obligations of the Parties under this Article XVII
shall not be impaired, reduced or otherwise affected as a result of any of
the following: (i) the receipt by a Party from any third party of any
amounts in reimbursement of Damages that are the subject of the Dispute; or
(ii) either Party has assigned or otherwise transferred any or all of its
rights and/or obligations under this Agreement as permitted hereunder.
Section 17.03. Continuing Obligations and Rights. When any Dispute
occurs and is the subject of friendly consultations or arbitration,
Contractor shall continue the Work in accordance with the Project Schedule
and the terms hereof and Owner shall continue to make payments of
undisputed amounts in accordance with this Agreement, and the Parties shall
otherwise continue to exercise their rights, and fulfill their respective
obligations, under this Agreement. While any friendly consultations or
arbitration is pending, neither Party shall exercise any other remedies
hereunder arising by virtue of the matters in Dispute.
Section 17.04. Interim Remedies. Before a notice to arbitrate is
given or prior to the selection of the arbitrator(s), nothing contained
herein shall prevent a Party from applying to a court that would otherwise
have jurisdiction for provisional or interim measures. After the
arbitrator(s) has been selected, they shall have sole jurisdiction to hear
such applications, except that any measures ordered by the arbitrator(s)
may be immediately and specifically enforced by a court otherwise having
jurisdiction over the Parties.
Section 17.05. Tolling Statute of Limitations. All applicable
statutes of limitation and defenses based upon the passage of time and
similar contractual limitations shall be tolled while the procedures
specified in this Article XVII are pending. The Parties will take such
action, if any, required to effectuate such tolling. Without prejudice to
the procedures specified in this Article XVII, a Party may file a complaint
for statute of limitations purposes, if in its sole judgment such action
may be necessary to preserve its claims or defenses. Despite such action,
the Parties will continue to participate in good faith in the procedures
specified in this Article XVII.
ARTICLE XVIII
MISCELLANEOUS
Section 18.01. Assignment.

1.0 PROJECT OVERVIEW
1.1 Introduction
The Scope of Work for the Owner Paris Power Project (Project) as contained
within this document is developed to provide definition to the Project.
Capitalized terms used herein, and not otherwise defined herein shall have
the meanings ascribed to them in the Turnkey Engineering, Procurement and
Construction Agreement for Combined Cycle Generation Facility between
Owner Paris Power, L.L.P. (Owner) and Duke/Fluor Xxxxxx (Contractor)
dated as of September 30, 1998.
The power plant shall be designed to provide all the electrical power
produced in excess of the internal parasitic loads to Texas Utilities
(Utility). The Plant shall deliver (net) approximately 1000 MW at 345 kV to
Utility. The primary power equipment will consist of four (4) General
Electric (GE) model PG 7241 FA combustion turbine generators; equipped
with inlet air evaporation coolers, four (4) three pressure level heat
recovery steam generators (HRSG) with intermediate pressure reheat;

21.0 MODES OF OPERATION
Six modes of operation for the plant have been identified: Normal Case,
Design Case, Turbine Bypass Case, Start-up Case, Grid Failure Case, and
Emergency Shutdown.
These cases are defined as:
21.1 Design Case: Design Case is 100% of total capacity with all four
combustion turbines and steam turbines in operation and is based on the
design basis fuel, water supply, design conditions and requirements of
Section 3. Power for running plant auxiliary systems supplied by plant.
21.2 Normal Cases:
- Four gas turbines and two steam turbines operating with the
facility output between 50 percent and 100 percent of total capacity.
- Two gas turbines and steam turbines operating with the
facility output between 25 percent and 50 percent of total capacity.
- One gas turbine and one steam turbine operating with the
facility output between 13 percent and 25 percent of total capacity.
- One gas turbine and one steam turbine operating with the
three gas turbines and the second steam turbine cycling on and
off line every 12 hours.
21.3 Turbine Bypass Case: The conditions of this case are:
- Trip of a steam turbine and no boiler safety valves lift
during all loading conditions.
21.4 Start-Up Case: This case can be either a cold or hot start. The
conditions of this case are similar to the turbine bypass case but with the
following clarification:
- During startup, initial steam production will be bypassed
until the steam is at a sufficient temperature and pressure
before being admitted to the steam turbine. It is intended that
the steam be admitted to the steam turbine as early as possible
so as to minimize thermal shock to the turbine and to minimize
bypass operation. However, should the steam turbine be unable to
accept the steam, the bypass system must be able to accommodate
steam production up to 125 percent of the rated steam production of one
HRSG.
