    (b)           Commencing
on the date hereof and for a period of one hundred twenty (120) days thereafter
and so long thereafter as may be extended upon the mutual agreement of the
Parties, which agreement shall not be unreasonably withheld (the “Screening
Period”), Holdco shall screen the BP Assets, the PD Assets, the Baker

reasonably request.  During the Screening Period and thereafter if
such assets are required to be transferred to Holdco or any Sub in accordance
with this Paragraph 4,
Higher Perpetual, Higher Power and Perpetual shall not solicit any offers,
market or enter into (or permit to exist) any agreement or Encumbrance affecting

offers, market or enter into any agreement respecting the Baker Assets or the
Haynes Assets (except as expressly provided for in this Agreement), written or
oral, with any other Person relating to the development, construction or
operation of Baker or Haynes that conflicts with the terms hereof or the
transactions contemplated by the Transactions Documents.

     

    (c)           If
at the end of the Screening Period, the aggregate Expected MWs of the BP Assets
and the PD Assets are less than 600 MW of installed capacity (the “Target
MWs”), with the approval of the Members, which shall not be unreasonably
delayed or denied, Holdco may elect by written notice delivered no later than
the first business day after the end of the Screening Period, to substitute the
Baker Assets and/or the Haynes Assets for either or both of the BP Assets and
the PD Assets, such that the Expected MWs of the assets owned and developed by
Holdco and the Subs equals or exceeds the Target MWs.  Upon such
election by Holdco, Higher Power on behalf of Higher Perpetual shall transfer
and assign the Baker Assets to the Baker Sub and/or the Haynes Assets to the
Haynes Sub, as applicable, free and clear of all Encumbrances other than
Permitted Encumbrances pursuant to an agreement substantially in the form of the

reasonably request.  Concurrently, the BP Sub shall transfer and
assign the BP Assets, and the PD Sub shall transfer and assign the PD Assets, as
applicable, to Higher Power on behalf of Higher Perpetual free and clear of all
Encumbrances created by, through or under Holdco or the Subs other than
Permitted Encumbrances, pursuant to an agreement in form and substance
reasonably acceptable to Holdco and Higher Power The assumed Installed Capacity
of the Wind Farms is set forth on Exhibit F
attached hereto.

    5.           Higher Perpetual and Holdco
Payment Obligations.

     

    (a)           Higher
Perpetual shall pay to Higher Power each Developer Fee on the date of the
applicable event specified in Paragraph 3, but
only to the extent such event occurs and such Developer Fee has not already been
paid by Perpetual pursuant to Paragraph 3 or
by any other Person and if Higher Perpetual and Perpetual (and all other
Persons) fail to make such payment within thirty (30) days of the applicable
event specified in Paragraph 3 (or if such payment is avoided, rescinded or must
otherwise be returned by Higher Power for any reason including as a result of
any insolvency, bankruptcy or reorganization proceeding) Holdco shall pay to
Higher Power such Developer Fee; provided however
that, Holdco’s liability for any Notice to Proceed Fee shall be limited to
$10,000 per megawatt of Installed Capacity and if Holdco shall pay such amount,
Higher Power shall have been paid in full for such Notice to Proceed Fee and
shall have no claim to Perpetual, Higher Perpetual, Holdco or their Affiliates
for any additional amount pursuant to this Agreement; provided further
however, that if Holdco pays such Notice to Proceed Fee for any Wind Farm and is
required to pay the Sale Fee for such Wind Farm, such Sale Fee to be paid by
Higher Perpetual and/or Holdco shall be $86,250 per megawatt of Installed
Capacity.  Perpetual and Higher Perpetual acknowledge and agree that
Holdco shall have the ability to collect from Higher Perpetual and Perpetual the
amount of such Developer Fees with interest accrued thereon at the rate of 15%
per annum from the date of such payment to but excluding the date of such
payment, and that any failure by Perpetual and Higher Perpetual to make such
payment shall entitle Holdco and DeWind to exercise their rights and remedies
under Section 4.08 of the LLC Agreement and other applicable law, which
may, among other things, result in a dilution of Higher Perpetual’s Membership
Interest under the LLC Agreement.  Holdco’s obligation to pay the
Developer Fees to Higher Power when due is not subject to the making and funding
of Capital Calls under the LLC Agreement. Each
of Higher Perpetual, Perpetual and Holdco waives, to the extent permitted by
law, any applicable surety defenses; provided that Holdco's waiver shall not
impair its ability to recover any payment of the Sale Fee with interest as
described in this Section 5(a) or the ability of Holdco and DeWind to exercise
their rights described in this Section 5(a).

     

    (b)           Holdco
shall upon Higher Power’s execution and delivery of the Contribution Agreement
on behalf of Higher Perpetual pay to Higher Power $607,500 in reimbursement for
funds currently on deposit with a government agency or other Person and assume
all rights and obligations of Higher Power with respect to all rights of Higher
Power pursuant to the interconnect applications as listed on Exhibit G
attached hereto.

     

    (c)           Before
Permanent Financing occurs for such Wind Farm, the BP Assets (or substituted
assets pursuant to Paragraph 4(c))
and/or the PD Assets (or assets substituted pursuant to Paragraph 4(c)) may
only be sold or otherwise disposed of to a Third Party if any unpaid Developer
Fees applicable to such Assets shall have been assigned to and assumed by the
acquiring Third Party pursuant to a written agreement under which Higher Power
would receive the related Developer Fees payable on the related Commercial
Operation Date.

Pringle, Palo Duro, Baker, Haynes, and (with respect to title work only) Little
Pringle One and Little Pringle Two in accordance with Prudent Wind Industry
Practices as set forth on Exhibit H attached
hereto.

     

    7.           Late
Payments.  In the event any payment (including Developer Fees)
due to either Party is not paid when such amount becomes due hereunder, then
interest shall accrue on such outstanding amount and shall be payable to such
Party at a rate of the Prime Rate as published in the Wall Street Journal plus two
percent per annum, or the maximum rate permitted by applicable law, whichever is
less.  Interest shall begin to accrue on the date payment was
due.

Agreement.  In order to induce one another to enter into this
Agreement, each of the Parties represents that it has determined that the terms
of this Agreement are fair and reasonable under all the circumstances and that
this determination has been based solely upon its independent judgment after
consulting with counsel, and that, in making this determination, it has had an
adequate opportunity to discuss and assess the merits of its
claims.

     

    16.           Severability.  If
and for so long as any provision of this Agreement shall be deemed to be judged
invalid for any reason whatsoever, such invalidity shall not affect the validity
or operation of any other provision of this Agreement except only so far as
shall be necessary to give effect to the construction of such invalidity, and
any such invalid provision shall be deemed severed from this Agreement without
affecting the validity of the balance of this Agreement.

or consents provided for or permitted to be given under this Agreement must be

Notwithstanding the foregoing, (a) the Parties may at any time seek

    2.1           In

defense of an inconvenient forum to the maintenance of such action or proceeding
in any such court.

     

    3.4           EACH
OF THE PARTIES HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY RIGHT
IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR
