(10) days after receipt of Written Notice thereof from Supplier;

10.2.3

Any representation or warranty of Buyer contained in this Agreement shall prove
to be false or misleading at the time such representation or warranty is made
and has a material adverse effect on either Party’s ability to perform its
obligations hereunder, and such false or misleading representation or warranty
and material adverse effect continue uncured for thirty (30) days after receipt
of Written Notice from Supplier;

10.2.4

Buyer voluntarily commences bankruptcy, insolvency, reorganization, stay,
moratorium or similar debtor-relief proceedings, or will have become insolvent
or generally does not pay its debts as they become due, or admits in writing its
inability to pay its debts, or makes an assignment for the benefit of creditors;

10.2.5

Insolvency, receivership, reorganization, bankruptcy, or a similar proceeding
shall have been commenced against Buyer and such proceeding remains undismissed
or unstayed for a period of ninety (90) days;

10.2.6

Except as otherwise expressly provided for in this Section 10.2, Buyer is in
material breach of its obligations under this Agreement and such material breach
continues uncured for thirty (30) days after receipt of Written Notice from
Supplier; or

10.2.7

A default in respect of Buyer shall have occurred and be continuing beyond the
applicable cure period therefor under the Wind Turbine Supply Agreement or the
Warranty Agreement.

10.3

Cure of an Event of Default

.  An Event of Default shall be deemed cured only if such default shall be
remedied within the relevant time period, if any, specified in Sections 10.1 and
10.2 after Written Notice has been sent to the defaulting Party from the
non-defaulting Party specifying the default and demanding that the same be
remedied (provided that the failure of a Party to provide such notice shall not
be deemed a waiver of such default).  Notwithstanding the

foregoing, in the event of a Supplier Event of Default set forth in
Sections 10.1.2, 10.1.4 or 10.1.6 or a Buyer Event of Default set forth in
Sections 10.2.3, 10.2.5 or 10.2.6, if such default is not reasonably capable of
cure within the relevant cure period set forth therein, but such default is
reasonably capable of cure within the additional cure period set forth in this
Section 10.3, then the default shall not be deemed a Supplier Event of Default
or a Buyer Event of Default, as applicable, if the defaulting Party commences to
remedy the default within the relevant cure period set forth therein and
thereafter diligently pursues such remedy until such default is fully cured;
provided, however, that in no event shall such additional period of time for the
defaulting Party to effect a cure for any such default exceed one hundred twenty
(120) days.  Notwithstanding anything contained herein, there shall be no
additional cure period allowed for a breach by Supplier under Section 10.1.5.  
Buyer agrees that it shall not terminate this Agreement in respect of any
Supplier Event of Default under Section 10.1 occurring with respect to Supplier,
but not Supplier Parent, if Supplier Parent shall have (i) cured in all material
respects all such Supplier Events of Default (other than the defaults under
Sections 10.1.3 or 10.1.4 , as applicable) and (ii) if there is then also a
Supplier Event of Default under Sections 10.1.3 or 10.1.4 , irrevocably assumed
this Agreement and the other Contract Documents.  Any such assumption shall be
pursuant to a written agreement reasonably acceptable to Buyer.  Supplier agrees
that it shall not terminate this Agreement in respect of any Buyer Event of
Default under Section 10.2 occurring with respect to Buyer, but not Buyer
Parent, if Buyer Parent shall have (i) cured in all material respects all such
Buyer Events of Default (other than the defaults under Sections 10.2.4 and
10.2.5 , as applicable) and (ii) if there is then also a Buyer Event of Default
under Sections 10.2.4 and 10.2.5 , irrevocably assumed this Agreement and the
other Contract Documents.  Any such assumption shall be pursuant to a written
agreement reasonably acceptable to Supplier.

10.4

Event of Default Remedies.

10.4.1

Termination by Buyer.  Upon the occurrence of a Supplier Event of Default which
remains uncured following expiration of any applicable cure period, Buyer,
without prejudice to any remedy provided herein or otherwise available at law or
in equity, may, by Written Notice to Supplier, terminate this Agreement.
 Subject to the rights and remedies for failure to meet the Availability set
forth in Exhibit D, the termination of this Agreement will be without prejudice
to any other rights or remedies which Buyer may have against Supplier, and no
termination of this Agreement will constitute a waiver, release or estoppel by
Buyer of any right, action or cause of action it may have against Supplier.

10.4.2

Termination by Supplier.  Upon the occurrence of a Buyer Event of Default which
remains uncured following expiration of any applicable cure period, Supplier,
without prejudice to any remedy provided herein or otherwise available at law or
in equity, may, by Written Notice to Buyer, terminate, or suspend performance
under, this Agreement.  The termination of, or suspension of performance under,
this Agreement shall be without prejudice to any other rights or remedies which
Supplier may have against Buyer, and no termination of, or suspension of
performance under, this Agreement shall constitute a waiver, release or estoppel
by Supplier of any right, action or cause of action it may have against Buyer.

10.5

Effect of Termination

.  No termination under Section 10.4 will release either Party from any
obligations arising hereunder prior to such termination.  The exercise of the
right

of a Party to terminate this Agreement, as provided herein, does not preclude
such Party from exercising other remedies that are provided herein or are
available at law or in equity; provided, that no Party will have a right to
terminate, revoke or treat this Agreement as repudiated other than in accordance
with the other provisions of this Agreement; and provided, further, that the
Parties’ respective rights upon termination will be subject to the liability
limitations of Article 7.  Except as otherwise set forth in this Agreement,
remedies are cumulative, and the exercise of, or failure to exercise, one or
more of them by a Party will not limit or preclude the exercise of, or
constitute a waiver of, other remedies by such Party.  

ARTICLE 11
INDEMNIFICATION

11.1

General

11.1.1

Indemnification by Supplier.  Supplier hereby agrees to indemnify, defend and
hold harmless Buyer and any Financing Party and any of their respective
officers, agents, shareholders, partners, members, employees, representatives,
consultants, advisors and/or their respective assigns (each a “Buyer Indemnified
Party”), from and against any and all Losses incurred or suffered by Buyer or
any Buyer Indemnified Party for (a) any violation of any Applicable Law or
Permit to be complied with hereunder by any Supplier Responsible Party; (b)
injury to or death of persons including employees of Supplier; and (c) any loss
of or physical damage to the property of any Buyer Indemnified Party or any
third parties to the extent not covered by Buyer’s insurance, and to the extent
they are the result of the intentional or negligent acts or omissions of
Supplier, its Subcontractors or any Person or entity directly employed by any of
them, or any Person or entity for whose acts any of them are liable during the
performance of Supplier’s obligations under this Agreement (collectively, the
“Supplier Responsible Parties”); provided, however, that Supplier shall have no
liability for damages to the proportionate extent resulting from any Buyer
Responsible Party’s performance or non-performance under this Agreement or the
negligence or willful misconduct of any Buyer Responsible Party.  The Parties
agree that obligations giving rise to the payment of liquidated damages under
this Agreement shall not give rise to a claim of indemnity under this
Section 11.1.1.

11.1.2

Indemnification by Buyer.  Buyer hereby agrees to indemnify, defend and hold
harmless Supplier and the Subcontractors and any of their respective officers,
agents, shareholders, partners, members, Affiliates, employees, representatives,
consultants, advisors and/or their respective assigns (each a “Supplier
Indemnified Party”), from and against any and all Losses incurred or suffered by
Supplier or any Supplier Indemnified Party for (a) any violation of any
Applicable Law or Permit to be complied with hereunder by any Buyer Responsible
Party; (b) injury to or death of persons including employees of Buyer; (c) any
loss of or physical damage to the property of any Supplier Indemnified Party or
any third parties, to the extent not covered by Supplier’s insurance, and to the
extent arising out of or resulting from the intentional or negligent acts or
omissions of Buyer, its subcontractors, or any Person or entity directly
employed by any of them, or any Person or entity for whose acts any of them are
liable during performance of Buyer’s obligations under this Agreement
(collectively, “Buyer Responsible Parties”); and (d) any failure of any Buyer
Responsible Party to pay for Sales Taxes for which Buyer is responsible pursuant
to this Agreement; provided, however, that Buyer shall

have no liability for any Losses to the proportionate extent resulting from any
Supplier Responsible Party’s performance or non-performance under this Agreement
or the negligence or willful misconduct of any Supplier Responsible Party.

11.2

Comparative Negligence

. It is the intent of the Parties that where, as between the Parties, negligence
is determined to have been joint or contributory, principles of comparative
negligence will be followed and each Party shall bear the proportionate cost of
any loss, damage, expense or liability attributable to that Party’s negligence.

11.3

Availability of Insurance

.  Notwithstanding anything to the contrary in this Article 11, neither Party
will be required to provide any indemnification to the other Party for any
Losses when and to the extent that insurance proceeds are available therefor.

11.4

Indemnification Procedure

.  When a Party hereunder (“Indemnifying Party”) is required to indemnify the
other Party (“Indemnified Party”) in accordance with this Article 11, the
Indemnifying Party will assume on behalf of such Indemnified Party, and conduct
with due diligence and in good faith, the defense of any claim against such
Party, whether or not the Indemnifying Party will be joined therein, and the
Indemnified Party will cooperate with the Indemnifying Party in such defense.
 The Indemnifying Party will be in charge of the defense and settlement of such
claim; provided, that without relieving the Indemnifying Party of its
obligations hereunder or impairing the Indemnifying Party’s right to control the
defense or settlement thereof, the Indemnified Party may elect to participate
through separate counsel in the defense of any such claim, but the fees and
expenses of such counsel will be at the expense of such Indemnified Party,
except in the event that (a) the Indemnified Party will have reasonably
concluded, acting in good faith and on the advice of counsel, that there exists
a material conflict of interest between the Indemnifying Party and the
Indemnified Party in the conduct of the defense of such claim (in which case the
Indemnifying Party will not have the right to control the defense or settlement
of such claim, on behalf of such Indemnified Party), or (b) the Indemnifying
Party will not have employed counsel to assume the defense of such claim within
a reasonable time after notice of the commencement of an action thereon, in
which case the fees and expenses of counsel will be paid by the Indemnifying
Party.  No Indemnifying Party will settle any such claims or actions in a manner
which would require any action or forbearance from action by any Indemnified
Party without the prior written consent of the Indemnified Party, which consent
will not be unreasonably withheld.

11.5

Survival

.  The provisions of this Article 11 shall survive the termination or expiration
of this Agreement.

ARTICLE 12
ARBITRATION

12.1

Arbitration Procedure

.  Any controversy, claim or dispute between the Parties hereto arising out of
or related to this Agreement, or the alleged breach, termination, or invalidity
hereof (“Dispute”), will be submitted for arbitration before a single arbitrator
in accordance with the provisions contained herein and in accordance with the
Commercial Arbitration Rules of the American Arbitration Association (“AAA”) in
effect at the time of the arbitration (“Rules”) (but such arbitration shall not
be required to be conducted under the auspices of AAA); provided,

however, that notwithstanding any provisions of such Rules, the Parties shall
have the right to take depositions (up to three (3) per Party) and obtain
documents from the other Party regarding the subject matter of the arbitration.
 Experts retained by a Party for the Dispute shall prepare reports in accordance
with Fed. R. Civ. P. 26, which reports shall be exchanged as directed by the
arbitrator.  If the Parties cannot agree upon an arbitrator within twenty (20)
days following the service of the Arbitration Notice, then the arbitrator shall
be selected pursuant to 9 U.S.C. sec. 5 or applicable state law.  Any Party
desiring arbitration shall serve on the other Party its notice of intent to
arbitrate (“Arbitration Notice”).  The Arbitration Notice shall be made within a
reasonable time after the Dispute has arisen, and in no event shall it be made
after the date when institution of legal or equitable proceedings based on such
Dispute would be barred by the applicable statute of limitations.  All
arbitration shall take place in the City of Chicago, Illinois, unless otherwise
agreed to by the Parties.  Each Party shall be required to exchange documents to
be used in the arbitration proceeding not less than fifteen (15) days prior to
the arbitration or as directed by the arbitrator.  The Parties shall use all
commercially reasonable efforts to conclude the arbitration as soon as
practicable.  The arbitrator shall determine all questions of fact and law
relating to any Dispute hereunder, including but not limited to whether or not
any Dispute is subject to the arbitration provisions contained herein.  The
arbitration proceedings provided hereunder are hereby declared to be
self-executing, and it shall not be necessary to petition a court to compel
arbitration.  Judgment upon the award rendered by the arbitrator may be entered
in any court having jurisdiction.

12.2

Attorneys’ Fees

.  In any arbitration or litigation to enforce the provisions of this Agreement,
the prevailing Party in such action shall be entitled to the recovery of its
reasonable legal fees and expenses (including reasonable attorneys’ fees and
legal costs), fees of the arbitrator, costs and expenses such as expert witness
fees, as fixed by the arbitrator or court without necessity of noticed motion.

12.3

Performance During Dispute

.  Subject to Section 10.4 with respect to a termination of this Agreement and
the right to suspend performance of obligations hereunder, while any
controversy, dispute or claim arising out of or relating to this Agreement is
pending, Buyer and Supplier shall continue to perform their obligations
hereunder notwithstanding such controversy, dispute or claim.

12.4

Third Parties

.  If a controversy, claim, dispute or difference arises between Buyer and
Supplier which is subject to the arbitration provisions hereunder and there
exists or later arises a controversy, claim, dispute or difference between Buyer
and/or Supplier and any third party arising out of or related to the same
transaction or series of transactions (“Third Party Controversy”), Buyer or
Supplier shall be entitled to require that (i) the other Party be joined as a
party to any arbitration of such Third Party Controversy being pursued with such
third party and Supplier or Buyer (as the case may be) shall permit, and
cooperate in, such joinder or (ii) the third party be joined as a party to the
arbitration proceeding hereunder; provided, however, that for purposes of clause
(i) above the third party must be a party to an agreement with Supplier or
Buyer, or Affiliate of Supplier or Buyer, which provides for arbitration of
disputes thereunder in accordance with rules and procedures substantially the
same in all material respects as provided for herein; and provided further that,
for purposes of clause (ii) above, the third party consents to such joinder
within ten (10) days after an Arbitration Notice has been filed.  Once a third
party is

joined to a dispute hereunder pursuant to this Section 12.4, such third party
shall be entitled to treatment as a Party for purposes of the arbitration
procedures of this Article 12.

12.5

Language

.  All arbitration proceedings shall be conducted in the English language.

12.6

Survival

.  The provisions of this Article 12 shall survive the termination or expiration
of this Agreement.

ARTICLE 13
SUCCESSORS AND ASSIGNS

13.1

Assignment

.  This Agreement shall be binding upon and shall inure to the benefit of the
successors and permitted assigns of Supplier and Buyer.  This Agreement, and any
rights or obligations hereunder, may only be assigned or otherwise transferred
in whole, and not in part.  Further, neither Party may assign this Agreement, or
any rights or obligations hereunder, except: (i) upon the prior written consent
of the other Party, which consent shall not be unreasonably withheld, provided
that Supplier shall have no obligation to consent to any assignment unless the
proposed assignee or transferee is (A) a creditworthy entity with a net worth at
least equal to the net worth of Buyer on the date of assignment or transfer and
(B) not a wind turbine manufacturer or an Affiliate of a wind turbine
manufacturer; (ii) to an Affiliate upon prior Written Notice to the other Party,
provided, however, that in the case of Buyer such Affiliate is (A) a
creditworthy entity with a net worth at least equal to the net worth of Buyer on
the date of assignment or transfer and (B) not a wind turbine manufacturer or an
Affiliate of a wind turbine manufacturer; (iii) to a Financing Party as
collateral security, upon prior Written Notice to the other Party; or (iv) upon
Written Notice to the other Party, to any entity succeeding to all or
substantially all of such Party’s assets.  Notwithstanding the foregoing, upon
any assignment of this Agreement by Supplier, the Supplier Parent Guaranty will
remain in full force and effect until Buyer is issued and accepts alternate
payment security.  No assignment or other transfer shall relieve either Party of
its respective obligations hereunder.  Any assignment not in conformity with
this Agreement shall be null and void and shall be deemed to be a material
breach of this Agreement.  For purposes of this Agreement, an assignment shall
be deemed to include any transfer or sale of all or substantially all of the
assets or business of a Party or a merger, consolidation or other transaction
that results in a change in control of a Party.

13.2

Certain Restrictions

.  Notwithstanding anything in this Article 13 to the contrary, (i) no Party may
assign or transfer this Agreement, in whole or in part, unless such assignment
or transfer is made together with the Wind Turbine Supply Agreement and
(ii) Buyer shall assign or transfer this Agreement to any purchaser of the
Project or any Person succeeding to substantially all of Buyer’s interests in
the Project.

13.3

Certain Expenses.

  If Supplier incurs any out-of-pocket cost or expense (including attorneys’
fees) in connection with any collateral assignment to or cooperation with any
Financing Party, or any regulatory treatment or approval sought by Buyer related
to this Agreement or the Project, Buyer shall pay Supplier for such reasonable
costs and expenses upon demand therefor.

13.4

Subcontracts

.  Buyer hereby agrees that Supplier may subcontract to a third party all or a
portion of the work to be performed hereunder, but the use of any Subcontractors
will not relieve Supplier of its responsibilities and obligations under this
Agreement nor relieve Supplier in any way from any liability arising hereunder.

ARTICLE 14
CONFIDENTIALITY AND PUBLICITY

14.1

Confidential Information

.  

14.1.1

A Party (the “Disclosing Party”) may disclose to the other Party (the “Receiving
Party”) certain non-public information of a sensitive commercial nature,
including the terms and conditions of this Agreement and all technical, product,
marketing, financial, personnel, planning, and other information (“Confidential
Information”).  Confidential Information marked “confidential,” “proprietary,”
or similar language may be orally so designated or may not be marked or
designated but is nevertheless non-public information of such Disclosing Party.
 Confidential Information is received by the Receiving Party in confidence and
in trust.  Accordingly, the Receiving Party shall use the Disclosing Party’s
Confidential Information only as expressly permitted by this Agreement and shall
limit the disclosure of Confidential Information to consultants, auditors,
employees, subcontractors or agents of the Receiving Party or any Financing
Party who have a need to know such Confidential Information for purposes
expressly authorized by this Agreement and who are bound in writing by
confidentiality terms no less restrictive than those contained herein; provided,
that the Receiving Party shall use commercially reasonable efforts to coordinate
with the Disclosing Party prior to the dissemination of Confidential Information
to such parties and shall give the Disclosing Party a reasonable opportunity to
object to such dissemination on the grounds that the proposed type or category
of Confidential Information is not being disseminated on a “need-to-know” basis.
 The Receiving Party shall provide to the Disclosing Party copies of its written
confidentiality agreements entered into with its consultants, auditors,
employees, subcontractors or agents (and in the case of Buyer, the Financing
Party) prior to any disclosure to such parties.  Nothing in this Section 14.1
shall prohibit either Party from disclosing to third parties the fact that it
has entered into this Agreement with the other Party, or to the extent
disclosure of information is required in connection with either Party’s
application for Permits.  Notwithstanding anything to the contrary contained
herein, the Receiving Party may disclose Confidential Information to the extent
required to comply with an order of a Governmental Authority with appropriate
jurisdiction or as required to be disclosed under Applicable Law or any
securities exchange requirement, provided that:

(i)

if the Receiving Party receives such an order, it shall promptly provide a copy
of such order to the Disclosing Party, and the Disclosing Party shall have the
right to seek to obtain a protective order or other remedy preventing or
limiting disclosure.  If such protective order or other remedy is not obtained,
the Receiving Party shall furnish only that portion of the Confidential
Information that it is advised in writing by counsel that it is legally required
to disclose.  The Receiving Party shall use diligent efforts to cooperate with
the Disclosing Party in its efforts to obtain reliable assurance that
confidential treatment will be accorded the Confidential Information; and

(ii)

if the Receiving Party is required to make a disclosure of Confidential
Information pursuant to any Applicable Law or any securities exchange
requirement, the Receiving Party shall first seek confidential treatment of such
Confidential Information, and in all such cases, the Disclosing Party shall have
the right to approve the description of such Confidential Information being
disclosed.

14.1.2

The Receiving Party shall notify the Disclosing Party immediately if the
Receiving Party learns of any misappropriation or misuse of the Confidential
Information and shall cooperate with the Disclosing Party to prevent such
misappropriation or misuse.  The Receiving Party shall return to the Disclosing
Party all Confidential Information upon written request or upon expiration or
termination of this Agreement and shall certify in writing that it has done so.

14.2

Publicity

.  Neither Buyer nor Supplier shall publish any drawing, photograph, video or
film or directly or indirectly disclose any information relating to the services
to be performed under this Agreement to the press, radio, television or other
news media without the prior written consent of the other Party (which consent
shall not be unreasonably withheld or delayed) and subject to such reasonable
conditions as may be prescribed by such Party.

14.3

Survival

.  The provisions of this Article 14 shall survive the termination or expiration
of this Agreement.

ARTICLE 15
GENERAL PROVISIONS

15.1

Waiver

any future occasion.

15.2

Right of Waiver

.  Each Party, in its sole discretion, shall have the right, but shall have no
obligation, to waive, defer or reduce any of the requirements to which the other
Party is subject under this Agreement at any time; provided, however, that
neither Party shall be deemed to have waived, deferred or reduced any such
requirements unless such action is in writing and signed by the waiving Party.
 A Party’s exercise of any rights hereunder shall apply only to such
requirements and on such occasions as such Party may specify and shall in no
event relieve the other Party of any requirements or other obligations not so
specified.

accordance with the following formula:

Availability (0-100%) = [ex104004.gif] [ex104004.gif]

Where:

(i)

“Calendar Hours” shall equal the total number of hours in the applicable
Production Period.

(ii)

“Supplier Controllable Hours” shall equal the total number of hours during the
applicable Production Period during which the relevant Wind Turbine was
unavailable to generate electricity due to one or more of the following:

(1)

the Wind Turbine being paused or withdrawn from use by Supplier for reasons
other than those covered in the definition of Supplier Uncontrollable Hours set
forth below; and

(2)

an error identified by the Wind Turbine controller that is defined as a
“Manufacturer responsibility” in the Error Code Allocation Table;

provided, however, that if any of the events described above in paragraphs (1)
and (2) occur simultaneously in the same hour, then the relevant hour shall only
be counted once in order to prevent double counting.

(iii)

“Supplier Uncontrollable Hours” shall equal the total number of hours during the
applicable Production Period during which the relevant Wind Turbine was
unavailable to generate electricity due to one or more of the following:

of infringement or improper use of intellectual property in relation to the
Turbine Equipment;

(3)

the Wind Turbine being paused or withdrawn from use by Buyer, or any employee,
subcontractor, agent or representative of Buyer (other than Supplier, its
Affiliates and Subcontractors) for any reason other than for safety reasons
related to a Defect;

(4)

the electric transmission or distribution system to which the Project is
interconnected operating outside the defined voltage, frequency limits, or other
operational parameters of the Wind Turbines;

(5)

defects in the Balance of Plant Work preventing or adversely affecting the
performance or operation of the Wind Turbine;

(6)

Buyer failing to provide Access to Supplier in accordance with Section 4.1 of
the Agreement or otherwise failing to comply with its obligations under the
Agreement in a manner that delays or prevents Supplier from performing its
obligations under the Agreement or otherwise prevents or adversely affects the
performance or operation of the Wind Turbine; and

(7)

an error identified by the Wind Turbine controller that is not defined as a
“Manufacturer responsibility” in the Error Code Allocation Table;

provided, however, that if any of the events described above in paragraphs (1)
through (7) occur simultaneously in the same hour, then the relevant hour shall
only be counted once in order to prevent double counting.

3.3

Availability Calculation Verification.  Promptly after Supplier calculates the
Measured Average Availability in accordance with Section 3.2, Supplier shall
provide to Buyer Written Notice of the results of such calculation.  Such notice
shall (a) include the calculated Measured Average Availability (including backup
information on which the calculation was based and reflecting the duration of
each fault and applicable error code from the Error Code Allocation Table,
applicable to such fault), (b) identify the number of hours that were subject to
the provisos regarding double counting in Section 3.2(b)(ii) and Section
3.2(b)(iii), and (c) identify the number of hours, and whether such hours were
treated as Supplier Controllable Hours or Supplier Uncontrollable Hours, in
which an error was identified in the Wind Turbine controller and the error code
for such error was mischaracterized by the controller.  Such notice shall
contain a statement that Buyer has ten (10) Business Days to respond to the
notice.  Buyer may, within ten (10) Business Days following receipt of the
foregoing notice, request in writing that the Parties meet to reconcile any
disagreements concerning the calculation of the Measured Average Availability.
 Following receipt of such a request, the Parties shall meet at a mutually
agreeable time and location to review the calculation of the Measured Average
Availability, and shall negotiate reasonably and in good faith to resolve any
disagreements concerning such calculation.

3.4

Availability Damages.  

(a)

To the extent that Availability Liquidated Damages are owed by Supplier to Buyer
hereunder, such damages shall be calculated in accordance with the following
formula:

Availability Liquidated Damages = (PAA – MAA)  LD Rate  Wind TurbinePROD

Where:

PAA =

“Projected Average Availability” for the relevant Production Period, which is
equal to:

90%

for the Production Period consisting of the first six (6) months of the First
Production Year;

95%

for the Production Period consisting of the second six (6) months of the First
Production Year; and

95%

for each subsequent Production Period.

MAA =

Measured Average Availability calculated for the relevant Production Period in
accordance with Section 3.2.

LD Rate =

$50 per MWh

Wind TurbinePROD =

The sum of net metered output (in MWh) of all Wind Turbines during the relevant
Production Period, as measured by Buyer’s revenue quality meter, divided by the
Measured Average Availability calculated for the relevant Production Period in
accordance with Section 3.2.

(b)

Supplier shall pay Availability Liquidated Damages, if any, to Buyer within
thirty (30) days after the date on which the calculation made pursuant to
Section 3.2 is approved in accordance with Section 3.3; provided, that if there
is a good faith dispute between the Parties regarding the calculation or the
responsibility for the failure, Supplier shall pay the undisputed portion of the
Availability Liquidated Damages and the balance, if any, shall be paid upon
resolution of such dispute in accordance with the dispute resolution provisions
set forth in Article 12 of the Agreement.

3.5

Availability Bonus.  

(a)

If for any Production Period, the Measured Average Availability for such
Production Period is greater than 96% for such Production Period, Buyer shall
pay Supplier a bonus for such Production Period (the “Availability Bonus”),
calculated pursuant to the formula set forth below:

Availability Bonus = (MAA – 96%   Bonus Rate  Wind TurbinePROD

Where:

MAA =

Measured Average Availability calculated for the relevant Production Period in
accordance with Section 3.2.

Bonus Rate =

50% of the LD Rate.

Wind TurbinePROD =

The sum of net metered output (in MWh) of all Wind Turbines during the relevant
Production Period, as measured by Buyer’s revenue quality meter, divided by the
Measured Average Availability calculated for the relevant Production Period in
accordance with Section 3.2.

(b)

Buyer shall pay Availability Bonuses, if any, to Supplier within thirty (30)
days after the date on which the calculation made pursuant to Section 3.2 is
approved in accordance with Section 3.3; provided, that if there is a good faith
dispute between the Parties regarding the calculation or the responsibility for
the failure, Buyer shall pay the undisputed portion of the Availability Bonuses
and the balance, if any, shall be paid upon resolution of such dispute pursuant
to the dispute resolution provisions set forth in Article 12 of the Agreement.

4.

Audit Rights.  Buyer shall have the right to review all data reasonably
necessary to verify the Measured Average Availability calculation provided by
Supplier pursuant to Section 3.3.  Supplier shall provide such information to
Buyer within ten (10) Business Days following receipt of a written request from
Buyer for such information.  If Buyer disputes the accuracy of any calculation
of the Measured Average Availability, including the allocation of faults as set
forth in the Error Code Allocation Table, Buyer shall notify Supplier in writing
no later than thirty (30) days following receipt of the foregoing information.
 Buyer’s rights under this Section 4 shall terminate ninety (90) days after
termination of the Agreement.

5.

Remedies Not a Penalty.  The Parties acknowledge and agree that it is difficult
or impossible to determine with precision the amount of damages that would or
might be incurred by Buyer as a result of the failure of the Wind Turbines to
maintain the Projected Average Availability.  It is understood and agreed by the
Parties that (i) Buyer shall be damaged by the failure of the Turbine Equipment
to maintain the Projected Average Availability, (ii) it would be impracticable
or extremely difficult to fix the actual damages resulting therefrom, (iii) any
sums which would be payable under this Exhibit D are in the nature of liquidated
damages, and not a penalty, and are fair and reasonable, and (iv) each payment
represents a reasonable estimate of fair compensation for the losses that may
reasonably be anticipated from each such failure.  Payment of the liquidated
damages set forth in this Exhibit D will be the sole and exclusive remedy of
Buyer and the sole and exclusive liability and exclusive measure of damages of
Supplier with respect to any failure of the Wind Turbines to maintain the
Projected Average Availability.  Once payment of such liquidated damages has
been paid, Supplier shall be relieved of any and all further liability in
respect of such failure.
