MGE and NIW II are sometimes referred to as the "parties."

1.

BACKGROUND INFORMATION, DEFINITIONS AND PURPOSE

1.1 Capitalized Terms. Unless otherwise defined in this Agreement, all capitalized terms in this Agreement shall have the meaning given them in a Substation Use and Easement Agreement dated December 13, 2004, between Northern and NEW II, a copy of which is attached to this Agreement as Exhibit 1, ("Substation Agreement"), a memorandum of which is recorded in the Worth County, Iowa records as document number 042691.

1.2 Substation Use and Easement Agreement Between Northern and NIW II. The Substation Agreement provides for easement rights pertaining to the Substation Property and use rights pertaining to the Phase I Substation, Phase II Substation and Combined Substation as those terms are defined in the Substation Agreement. MGE's rights under this Agreement are derivative of NIW II's rights by assignment and conveyance to MGE of MGE's Proportionate Share of NIW II's rights under the Substation Agreement and by purchase and conveyance of MGE's Proportionate Share of NIW II's ownership interest in the Exercise Property. MGE shall by reason of its ownership, to the extent of its Proportionate Share, enjoy the benefits of, and share the burdens of, MW II's rights and obligations under the Substation Agreement.

1.3 MGE Asset Purchase Agreement. NIW II and MGE are parties to an Asset Purchase Agreement dated and executed contemporaneously with this Agreement ("Asset Purchase Agreement") to which this Agreement is attached as Exhibit C. Pursuant to the terms of the Asset Purchase Agreement, MGE purchased a developed site and other rights necessary to

enable MGE to construct wind turbines with a total nameplate generating capacity not to exceed 29.7MW consisting of 18 1.65MW Vestas V82 wind turbines ("MGE Unit") to be in Commercial Operation on or before December 31, 2007. The MGE Unit constitutes a Future Generating Facility as defined in the Substation Agreement.

1.4 NIW II Top of Iowa Wind Farm Phase H. NIW II expects to construct the Top of Iowa Wind Farm Phase II ("Phase II Wind Farm"), a Future Generating Facility as defined in the Substation Agreement, consisting of wind turbines with total nameplate generating capacity up to 80.3MW to be in Commercial Operation on or before December 31, 2007. The Phase II Wind Farm may be one project under single ownership or may be two or more units each under separate ownership (each a "Unit"). The Unit or Units owned by NIW II are collectively referred to as the "NIW II Unit." Each of the NIW II Unit(s) constitute(s) a Future Generating Facility as defined in the Substation Agreement. NIW II, subject to the terms of this Agreement, will also construct the Phase II Substation to be ready to serve the MGE Unit and NIW H Unit(s) at or prior to the time each is ready to begin Commercial Operation.

1.5 Purpose. The purpose of this Agreement is to grant to MGE, subject to the terms of this Agreement and the Substation Agreement, all necessary rights to deliver the electricity produced by the MGE Unit to the Interconnection Point as defined in and in accordance with the Phase II Interconnection Agreement through NIW II's Transformer ("MW II Transformer") located in the Phase II Substation, together with all consents and reciprocal easements necessary to allow MGE access to the Combined Substation as reasonably needed for enjoyment of the rights granted in this Agreement and in the Asset Purchase Agreement.

2.

GRANT TO MGE OF NON-EXCLUSIVE ACCESS AND TRANSFORMER SHARING RIGHTS.

MGE's rights under this Agreement are derivative of MW H's rights under the Substation Agreement and MGE shall, to the extent of its Proportionate Share, enjoy the benefits of, and share the burdens of, NIW H's rights and obligations under the Substation Agreement. Subject to the terms and conditions of use set forth in the Substation Agreement, MW II grants to MGE (such grant constituting a partial "Assignment" within the meaning of Section 11.1 of the Substation Agreement) non-exclusive access to the Combined Substation to connect the MGE Unit to a tap or taps, as designated by NIW II, on the NIW II Transformer. The tap(s), MW II Transformer, related switches and equipment shall be sufficient to transmit and deliver energy generated by the MGE Unit through the NM II Transformer and Combined Substation to the interconnection point with the 161 Line (as that term is defined in the Substation Agreement) in compliance with the Substation Agreement and the Phase II Interconnection Agreement. This grant includes all access, transmission and communications easements, rights-of-way and any other easements and rights-of-way reasonably required in connection with such non-exclusive use of the Combined Substation including, but not limited to, an easement for installation of buried or above ground electrical collection lines and communications lines from the public right of way to their point of connection, as applicable, with the NIW II Transformer or communications and data system of the Phase II Substation. The rights granted MGE in this Agreement shall terminate as and when provided in Sections 2 and 4, as applicable, of the Substation Agreement.

3.

ALLOCATION OF INTERCONNECTION CAPACITY TO MGE

NIW II hereby allocates to MGE, subject to the terms of this Agreement, for MGE's use to serve the MGE Unit, subject to the terms of this Agreement and subject to the terms of the Phase II Interconnection Agreement, exclusive access to 29.7MW of NIW II's interconnection rights

under the Phase II Interconnection Agreement. The rights granted MGE under this Section shall terminate at the same time as NIW II's rights under the Phase II Interconnection Agreement terminate, or upon termination of this Agreement, if that is earlier.

4.

SUBSTATION IMPROVEMENTS.

4.1(a) Design and Construction. NIW-II shall be responsible for design and construction of the Phase II Substation and interconnection structure, switches and other facilities comprising the Phase II Substation, including the NIW II Transformer which shall be a 112 MVA transformer, with taps as reasonably required by MGE^. to allow connection of the MGE Unit to the low side of the NIW II Transformer. MGE, at its expense, shall have the right to review and approve the plans and specifications for the Phase H Substation and for the NIW II Transformer, which review and approval shall not be unreasonably withheld, delayed or conditioned. NIW II's design and construction of the Phase II Substation shall conform to the most current version of the National Electric Safety Code and be in accordance with prudent utility practice. Materials used to construct the Phase II Substation shall be of utility grade. MGE and NIW-II shall share the costs of constructing the Phase II Substation, including the MW II Transformer, in proportion to the nameplate capacity of the MGE Unit and NIW II Unit(s) to the total Units utilizing the NIW II Transformer (as to each of MGE and MW II, its "Prorata Portion"). MGE's Prorata Portion is 29.7/110 and NIW II's Prorata Portion is 80.3/110. MGE and MW II each shall be solely responsible for design and construction of its respective electrical collection lines within the MGE Unit and the NIW II Unit, and those located on the Combined Substation connecting the respective Units to the MW II Transformer, and for the cost of making and testing, as necessary, their respective connection(s) to the tap(s) provided on the MW II Transformer.

4.1(b) Design and Construction Milestones. MGE and NIW II recognize and acknowledge that time is of the essence in the completion of construction of the Phase II Substation. The Phase II Substation shall be energized and capable of delivering energy from the MGE Unit by no later than July 31, 2007 (the "Energization Date"). In order to meet the Energization Date, the Parties agree to the following design and construction milestone schedule (the "Milestones"):

(1)

NIW II shall deliver the specifications for the Phase II-Transformer ("Transformer Specifications") to MGE by no later than October 15, 2006.

(2)

MGE shall review the Transformer Specifications by no later than October 20, 2006.

(3)

NIW II shall order the Phase II Transformer (for which MGE has approved the Specifications) by no later than November 1, 2006.

(4)

NIW II shall deliver the plans and specifications for the Phase II Substation (the "Substation Plans") to MGE and parties required to approve the Substation Plans under the Substation Agreement by no later than December 1, 2006.

(5)

MGE shall review the Substation Plans by no later than February 1, 2007. NIW II use its best efforts to ensure that parties required to approve the Substation Plans do so no later than February 5, 2007.

(6)

NIW II shall have fully executed contracts for the construction of the Phase II Substation with contractors reasonably acceptable to MGE by no later than March 1, 2007.

(7)

NIW II shall have begun significant construction activities by no later than April 1, 2007.

(8)

NIW II shall ensure that all of the equipment needed for the Phase II Substation (including but not limited to the transformer, switch gear, circuit breakers, and high-voltage meters) is delivered to the construction site by no later than June 30, 2007..

(9)

NIW II shall ensure that the Phase II Substation is energized and capable of delivering energy from the MGE Unit by no later than July 31, 2007.

In the event that NIW II fails to meet any Milestone, MGE shall have the right, but not the obligation, to take over and complete the construction of the Phase II Substation. MGE's right to take over and complete the construction of the Phase II Substation is in addition to any other remedy that MGE has under this Agreement or pursuant to law or equity. The grant of easement rights to MGE under Section 8.1 of this Agreement shall be expressly applicable to any takeover of construction by MGE. NIW II shall be responsible for and shall reimburse MGE for NIW II's Prorata Portion plus any additional design and construction costs related to NIW II's failure. If such reimbursement is made on or before December 31, 2008, whether by payment or offset under the terms of the Asset Purchase Agreement, all of NIW II's rights in the Phase II Substation and under this Agreement and the Substation Agreement shall be fully and automatically restored without further action by NIW II or MGE. If such reimbursement is not made on or before December 31, 2008, then MGE shall have the right upon thirty days written notice to MW II to declare a forfeiture of and assume ownership of NIW II's rights in the Phase II Substation, this Agreement and the Substation Agreement.

4.2

Allocation of Costs of Construction. MGE shall reimburse NIW II for its Prorata

Portion of the direct costs incurred in constructing the Phase II Substation and interconnection structure in compliance with the Substation Agreement and the Phase II Interconnection Agreement, including any changes to or upgrades of the Phase I Substation needed to accommodate the addition of the Phase II Substation and any upgrades required under the Interconnection Agreement as it may be amended or modified or as may be required by MISO or LPL, less any reimbursements received for the upgrades (collectively, "Construction Costs"). The cost of capacitor banks and other equipment needed solely due to characteristics of the turbines chosen by either NW/ II or MGE for its respective Unit(s) shall be borne by the party for whom the cost was incurred. This is not directly addressed in the term sheet, but seems fair if different turbines are used with differing equipment requirements.

4.3

Installation of Meters. Notwithstanding the foregoing, MGE and NIW-II, each at
its own cost, will install meters at the low side of the transformer.

4.4 Credit Enhancement by MGE. When NIW II contracts for the purchase of the NIW II Transformer ("Transformer Contract"), MGE shall become a party to the Transformer Contract and shall be fully liable thereunder for the purpose of assuring the supplier of the NIW II Transformer of timely payment of all amounts due under the Transformer Contract. This provision shall not affect the obligations of NIW II and MGE to make payment of Construction Costs as provided herein. To the extent MGE actually advances funds under this Section in excess of its Prorata Portion of amounts due under the Transformer Contract, MGE shall have the right to offset and deduct such excess from any payments due NIW II or its assigns hereunder or under the Asset Purchase Agreement.

4.5 Payment of Construction Costs. When NIW II contracts for the design, construction and equipping of the Phase II Substation including the NIW II Transformer and any changes to or upgrades of the Phase I Substation needed to accommodate the addition of the Phase II Substation, and purchase of equipment to be installed in the Phase II Substation, NIW II shall furnish to MGE copies of all contracts, purchase orders for such design, construction and equipment (collectively, "Construction Contracts"). NIW II shall promptly furnish to MGE copies of all invoices received by NIW II pursuant to the Construction Contracts and for any other Construction Costs incurred as provided in Section 4.1. MGE shall reimburse NIW II for its Prorata Portion of all Constructions Costs incurred and paid by NIW II within 15 days after receipt of the invoices from NIW II.

5.

SUBSTATION OPERATION AND METERING

5.1 Operation and Maintenance Costs. The NIW II Transformer and the Phase H Substation shall be owned by the parties as tenants-in-common, each owning an undivided interest in the assets, based on the Prorata Portion of the respective party. MW II shall promptly furnish to MGE copies of all invoices received by NIW II for Necessary Expenses incurred pursuant to the Substation Agreement, other costs of operating and maintaining the Phase II Substation including the MW II Transformer (collectively "O&M Costs"). MGE, within 15 days after receipt of the invoices from NIW II, shall reimburse NIW II for its Prorata Portion of all O&M Costs incurred and paid by MW II. NIW II and MGE shall each have the right, but not the duty, to advance payment in full any O&M Costs including Necessary Expenses and the other party, within thirty (30) days after receipt of a statement for the expenses thus advanced, shall reimburse the party making the advance an amount equal to that party's Prorata Portion of the total amount advanced. NIW II shall provide MGE as soon as practicable with written notice of the receipt of any notice of default under the Substation Agreement or the Phase II Interconnection Agreement and MGE may cure any such default. If NIW II breaches its obligations to operate and maintain the MW II Transformer and the Phase II Substation, and fails to cure any such breach within 30 days after receipt of notice of breach (or in such shorter time period if necessary to avoid imminent damage to the MW II Transformer and Phase II Substation), MGE may take such reasonable actions as it, in its sole discretion, deems reasonably necessary to remedy such breach, provided such actions shall not interfere with MW ifs or Northern's use of the Combined Substation. In the event that NIW II's actions or inaction, in the reasonable judgment of MGE, may result in termination within the next 90 days of the Substation Agreement under Section 2 thereof, MGE shall notify NIW II of the measures MGE contends are necessary to prevent such termination. If NIW II within thirty days after receipt of such notice, fails to take action adequate to prevent termination of the Substation Agreement, MGE may take over operation and maintenance of the Phase II Substation, in which case MW II shall assign its

rights under the Substation Agreement to MGE and NIW II shall pay MGE its Prorata Portion of the O&M Costs, to the extent necessary to prevent termination of the Substation Agreement. NIW II shall have the right and option for one year following its assignment of rights to MGE to reacquire the interests transferred pursuant to this Section upon reimbursing MGE for costs actually incurred by MGE to prevent termination of the Substation Agreement.

 5.2 Metering Equipment and Location. NIW II shall provide, install, or arrange for transmission owner to install, and shall operate, maintain, and read, appropriate meters in compliance with the requirements of the Article 10 of the Interconnection Agreement ("Project Metering"). Such meters shall be used for quantity measurements under this Agreement. MGE, at its sole expense, may install and maintain check Meters, SCADA devices, and all associated metering and communication equipment to permit an accurate determination of the quantities of capacity and energy delivered under this Agreement; provided, however, that such equipment shall be operated and maintained in a manner that complies with the Interconnection Agreement and does not interfere with the installation, maintenance and operation of Project Metering and associated measuring equipment or the Combined Substation and interconnection facilities. ).

The Project Metering shall be at the Delivery Point. MW II and MGE and owners of other Units, if any, in the Phase II Wind Farm shall each install a meter or meters at the low side of the MW II Transformer to determine how much energy each Unit is delivering to the transformer and how much is being delivered by the remainder of the Units in the Phase II Wind Farm. Output as metered at the Delivery Point will be assumed to be in the same proportions as the metered, low side inputs. If permitted by MISO under the Phase II Interconnection Agreement, and agreed by all parties using the Phase II Substation, low-side compensated meters may be used in lieu of the low side/high side metering combination described in this Section and in Section 4.3.

 5.3 Measurements. Readings of Project Meter shall be conclusive as to the amount of energy delivered onto the power grid through the MW II Transformer, and the low side meters as to the amount of energy delivered to the NIW II Transformer. In the event the Project Meter or low side meter is out of service or is determined, pursuant to this Section 5.3, to be registering inaccurately, measurement of energy delivered shall be determined by:

(a)

Check meter(s), if installed and registering accurately; or

(b)

In the absence of an installed and accurately registering check meter, by making a mathematical calculation if upon a calibration test of Project Meter or the low side meters, a percentage error is ascertainable; or

(c)

In the absence of both an installed and properly registering check meter or low side meters and an ascertainable percentage of error, estimating by reference to quantities measured during periods of similar conditions when the Project Meter or low side meters were registering accurately; or

(d)

If no reliable information exists as to the period over which such meter was registering inaccurately, it shall be assumed for correction purposes hereunder that such inaccuracy began at a point in time midway between the testing date and the last previous date on which such meter was tested and found to be accurate, but not to exceed six months prior to the testing date.

 5.4 Testing and Correction. The accuracy of each Project Meter shall be tested and verified as provided in the Interconnection Agreement and the cost of test shall be a Necessary Expense. MGE and NIW II shall have the right to access, with reasonable notice to the other and at reasonable times, to the other party's low side meters in order to test and verify the accuracy of such meters' measurements and recordings. Such inspections and verifications shall be at the sole expense of the party making the inspection. If any party or power purchaser entitled to do so under its power purchase agreement has installed a check meter the party or power purchaser shall test and verify each such meter shall be accurate within a one percent (1%) variance in accordance with commonly accepted meter testing procedures. Each party to this Agreement and power purchaser entitled to do so under its power purchase agreement shall have the right to be present when any other party is performing any maintenance and testing on the meters provided it has given the other party reasonable notice of its desire to be present. Each party shall bear the cost of the testing of its own meters. If either party disputes a meter's accuracy or condition, it shall so advise the owner of the meter in writing. The owner of the meter shall, within fifteen (15) days after receiving such notice, advise the disputing party in writing as to its position concerning the meter's accuracy and reasons for taking such position. If the parties are unable to resolve their disagreement through reasonable negotiations, then either party may submit such dispute to an unaffiliated third-party engineering company mutually acceptable to the parties to test the meter. If the tested meter is found to be registering within the permitted variance indicated in the Interconnection Agreement, and a low side meter is found to be registering within the permitted one percent (1%) variance, the disputing party shall bear the cost of inspection; otherwise, the cost shall be borne by the owner of the meter. Any repair or replacement shall be made at the owner's expense as soon as practicable, based on the third-party engineer's report. If, upon testing, any meter is found to be accurate or to be in error by not more than the permitted 1% variance, previous recordings of such meter shall be considered accurate in computing deliveries hereunder, but if in error, such meter shall be promptly adjusted to record correctly. If, upon testing, any meter shall be found to be in error by an amount exceeding the permitted 1% variance, then such meter shall be promptly adjusted to record properly and any previous recordings by such meter shall be adjusted in accordance with Section 5.3 hereof. If, upon testing, any meter is found to be in error by more than the permitted variance indicated in the Interconnection Agreement, the payments for energy shall be adjusted to reflect the corrected measurements determined pursuant to Section 5.3. The party paying such difference shall also pay interest at the prime rate and such payment (including such interest) shall be made within

thirty (30) days of receipt of a corrected billing statement.

-

 5.5 Maintenance and Records. The parties shall provide for their respective low side meters to be read on a daily basis and for the Project Meter to be read on a daily basis or as more frequently required under the Phase II Interconnection Agreement. MGE and NIW II shall furnish to each all data from their respective low side meters and the Project Meter for the purpose of calculating each party's Proportionate Share of the energy produced and delivered to the Interconnection Point as defined in the Phase II Interconnection Agreement. Data from the Project Meter shall be provided to NIW II and MGE no later than the time it is provided to MISO. A party desiring real time compensated low side metering, if permitted by MISO under the Phase H Interconnection Agreement, and if agreed by all parties using the Phase II Substation, may at its own expense install such meters as are agreed and permitted. Each party shall have the right to be present whenever the other party reads, cleans, changes, repairs, inspects, tests, calibrates, or adjusts the equipment used in measuring or checking the measurement of the energy delivered through the NIW II Transformer to the 161 Line. Each party shall give at least forty-eight (48) hours notice to the other Party in advance of taking any such actions. The records from each party's measuring equipment shall remain the property of that party, but, upon request, each party

will submit to the other its records and charts, together with calculations therefrom, for inspection, verification and copying, subject to return within ten (10) days after receipt thereof.

6.

TERM AND REMOVAL OF SUBSTATION.

The term of this Agreement and of the consents and easements granted in it ("Term") shall coincide with the Term of the Substation Agreement unless sooner terminated by MGE. MW II agrees that, despite the fact it may be permitted under Section 4 of the Substation Agreement, NIW II shall not remove any part of the Combined Substation it owns if such removal will affect the safety or operation of equipment necessary to MGE's exercise and enjoyment of the rights granted MGE in this Agreement. Should Northern desire to remove equipment from the Combined Substation that is necessary to the parties' exercise and enjoyment of their respective rights in the Combined Substation, NIW II and MGE shall each pay its respective Proportionate Share of the cost; should the equipment to be removed affect only MGE or MW II, the affected party shall pay the entire cost. NIW II at the request of MGE and subject to the above payment terms, shall exercise its rights pursuant to Section 4 of the Substation Use Agreement to purchase any of such equipment to be removed and shall leave it in operation for the Term of this Agreement or such lesser period of time that it is necessary to MGE's exercise and enjoyment of the rights granted MGE in this Agreement.

7.

CONDITIONS OF USE BY MGE.

7.1 Payment of Construction Costs, Refund of Reimbursements for Upgrades. NIW II shall not be required to allow the MGE Unit to use the MW II Transformer until MW-II has been reimbursed for the MGE Unit's Prorata Portion of the Construction Costs. MGE's Prorata Portion of reimbursements, including interest, received by MW II for any upgrades that may be required under the Phase II Interconnection Agreement shall be refunded to MGE as and when received by NIW II.

7.2 Operation and Maintenance. During the Term, MGE shall: (a) pay all amounts due to NIW II under this Agreement for O&M Costs as provided in Section 5.1, including, without limitation, Necessary Expenses and costs of operating and maintaining the NIW II Transformer, and (b) not interfere with the operation and maintenance of the MW II Unit(s) or the Wind Farm in any manner. NIW II shall not change, use or modify the Combined Substation so as to prevent or interfere with MGE's use of the Combined Substation or the energy production of the MGE Unit

If MGE or NIW II experiences operating difficulties with any portion of its generation facilities and the parties dispute the cause of such difficulties, the parties shall as quickly as reasonably possible implement a solution (permanent or temporary) that will minimize total lost revenues or damage. MGE shall cooperate with NIW II in fulfilling its obligations under Section 5 of the Substation Agreement. Thereafter, MGE shall cooperate with NEW II and Northern to promptly determine the cause of the difficulties, using if necessary the services of appropriate unaffiliated third party experts, and as between MGE and NIW II, the party found to have caused the difficulty shall reimburse the other and/or Northern (if required to do so under the Substation Agreement) for lost revenue and reasonable out of pocket expenses incurred to investigate, mitigate and cure such difficulties.

MGE or MW II shall each have the right, but not the duty, to advance payment in full any Necessary Expenses or other sums payable under this Agreement and the other party, within

thirty (30) days after receipt of a statement for the expenses thus advanced, shall reimburse the party making the advance an amount equal its Prorata Portion of the total amount advanced.

8.

FINANCING AND ASSIGNMENT.

12.1 Right to Mortgage and Assign. MGE and NIW II may, upon notice to the other party, without the other party's consent or approval, mortgage, collaterally assign, or otherwise encumber and grant security interests in all or any part of their respective interest in this Agreement, the Phase I Substation, the Phase II Substation, NIW II Transformer, the Substation Property, the MGE Unit, and NIW II Unit(s) (collectively, "Wind Farm Assets"). These various security interests in all or a part of the Wind Farm Assets are collectively referred to as "Mortgages" and the holders of the Mortgages, their designees and assigns are referred to as "Mortgagees." The Mortgages shall comply with and be subject to the terms of the Substation Agreement and this Agreement. MGE and MW II shall also have the right without the other party's consent to sell, convey, lease; or assign all or any portion of its Wind Farm Assets on either an exclusive or a non-exclusive basis, or to grant sub-easements co-easements, separate easements, leases, licenses or similar rights, however denominated (collectively, "Assignment"), to one or more persons or entities (collectively, "Assignees"). Assignees and Mortgagees shall use the Wind Farm Assets only for the uses permitted under this Agreement. Assignees and Mortgagees shall have all rights and remedies allowed them under then existing laws except as limited by their individual agreements with MGE or MW II.

12.2 Mortgagee/Assignee Obligations. Any Mortgagee or Assignee that does not directly hold an interest in the Wind Farm Assets, or whose interest is held solely for security purposes, shall have no obligation or liability under this Agreement prior to the time the Mortgagee or Assignee directly holds an interest in this Agreement, or succeeds to absolute title to MGE's or to NIW II's interest. A Mortgagee or Assignee shall be liable to perform obligations under this Agreement only for and during the period it directly holds such interest or absolute

title. Any Assignment permitted under this Agreement shall release MGE, NIW II or other assignor from obligations accruing after the date that liability is assumed by the Assignee.

12.3 Right to Cure Defaults/Notice of Defaults/Right to New Agreement. To prevent termination of this Agreement or any rights or easements created by this Agreement, or any partial interest in such rights or this Agreement, MGE, NIW II, any Mortgagee or Assignee shall have the right, but not the obligation, at any time to perform any act necessary to cure any default and to prevent the termination of this Agreement or any interest in the Wind Farm Assets.

12.4 Extended Cure Period. If any default by MGE or NIW II under this Agreement cannot be cured without obtaining possession of all or part of the Wind Farm Assets, then any such default shall be deemed remedied if a Mortgagee or Assignee: (a) within sixty (60) days after receipt of notice of the default acquires possession of all or part of the Wind Farm Assets, or begins appropriate judicial or nonjudicial proceedings to obtain the same; (b) diligently prosecutes any such proceedings to completion; and (c) after gaining possession of all or part of the Wind Farm Assets performs all other obligations as and when the same are due in accordance with the terms of this Agreement. If a Mortgagee or Assignee is prohibited by any court or by operation of any bankruptcy or insolvency laws from commencing or prosecuting the proceedings described above, the sixty (60) day period specified above for commencing proceedings shall be extended for the period of such prohibition.

12.5 Certificates, etc. MGE and NIW II shall execute estoppel certificates (certifying as to truthful matters, including without limitation that no default then exists under this Agreement, if such be the case), and consents to assignment and non-disturbance agreements as MGE, NIW II, or any Mortgagee or Assignee may reasonably request from time to time. The party who requests such certificates shall pay the reasonable expenses of the other parties to negotiate and review such requested certificates, or such costs may be shared as the parties may otherwise agree. MGE and NIW II shall cooperate in amending this Agreement from time to time to include any provision that may be reasonably requested by MGE, NIW II or any Mortgagee or Assignee to implement the provisions contained in this Agreement or to preserve a Mortgagee's security interest

13. MORTGAGEE PROTECTION.

13.3 New Agreement.

13.3(a) If this Agreement terminates because of MGE or NIW II's default, if the rights granted in this Agreement are foreclosed, or if this Agreement is rejected or disaffirmed pursuant to bankruptcy law or other law affecting creditor's rights and, within ninety (90) days after such event, MGE, NIW II or any Mortgagee or Assignee shall have arranged to the reasonable satisfaction of the non-defaulting party for the payment of all fees or other charges due and payable by MGE or NIW II as of the date of such event, then such non-defaulting party shall execute and deliver to MGE, NIW II or such Mortgagee or Assignee or to a designee of one of these parties, as the case may be, a new agreement affecting the Substation Property which (i) shall be for a term equal to the remainder of the Term before giving effect to such rejection or termination; (ii) shall contain the same covenants, agreements, terms, provisions and limitations as this Agreement (except for any requirements that have been fulfilled by MGE, NIW II or any Mortgagee or Assignee prior to rejection or termination of this Agreement); and, (iii) shall include that portion of the Wind Farm Assets in which MGE, NIW II or such other Mortgagee or Assignee had an interest on the date of rejection or termination.

13.3(b) After the termination, rejection or disaffirmation of this Agreement and during the period thereafter during which any Mortgagee shall be entitled to enter into a new agreement affecting the Substation Property, the non-defaulting party will not terminate the rights of any Assignee unless in default under its Assignment.

13.3(c) If more than one Mortgagee makes a written request for a new agreement pursuant to this provision, the new agreement shall be delivered to the Mortgagee requesting such

new agreement whose Mortgage is prior in lien, and the written request of any other Mortgagee whose lien is subordinate shall be void and of no further force or effect.

13.3(d) The provisions of this Section 12 shall survive the termination, rejection or disaffirmation of this Agreement and shall continue in full force and effect thereafter to the same extent as if this Section 13 were a separate and independent contract made by MGE, NIW II and each Mortgagee, and, from the effective date of such termination, rejection or disaffirmation of this Agreement to the date of execution and delivery of such new agreement, such Mortgagee may use and enjoy the Substation Property without hindrance by the non-defaulting party or any person claiming by, through or under either of them; provided that all of the conditions for the new agreement as set forth above are complied with.

13.3(e) The party requesting or receiving the new agreement shall pay the non-defaulting party's reasonable legal fees and other out of pocket expenses related to preparation, review, execution and delivery of the new agreement.

13.4 Mortgagee's Consent to Amendment, Termination or Surrender. Notwithstanding any provision of this Agreement to the contrary, the parties agree that so long as there exists an unpaid Mortgagee, this Agreement shall not be modified or amended, and neither MGE or MW II shall not accept a surrender, cancellation or release of all or any part of the Wind Farm Assets from MGE or MW II, prior to expiration of the Term without the prior written consent of the Mortgagee. This provision is for the express benefit of and shall be enforceable by each Mortgagee as if it were a party named in this Agreement.

13.5 No Merger. There shall be no merger of this Agreement or of the rights created under this Agreement with the fee or any other estate in the Substation Property by reason of the fact that this Agreement or any interest in this Agreement may be held, directly or indirectly, by or for the account of any person or persons who shall own any other interest in the Substation Property.

Midwest Renewable Energy Corporation ("MREC") holds an option to purchase additional real property adjacent to the Substation Property as shown in the drawing attached as Exhibit A ("Expansion Property") that it intends to assign to NIW II. If MREC or NIW II exercises its option to purchase all or a portion of the Expansion Property ("Exercise Property"), the legal description of the Substation Property, without additional action or documentation by the parties, shall be amended to include the Exercise Property.

1.2 IPL Easement. IPL is the grantee and holder of easement rights for an existing 161 kV transmission line located generally at the east end of the Substation Property and Expansion Property ("161 Line") under an easement recorded in Real Estate Deed Record 27,

#1187 of the Worth County Records ("IPL Easement"). A copy of the IPL Easement is attached to this Agreement as Exhibit B.

1.3 Phase I Substation. Northern, at its expense, has constructed an electrical substation ("Phase I Substation") on the Substation Property. The Phase I Substation consists of all fencing, security devices, electrical lines, meters, monitoring equipment, switches, transformers, and other electrical equipment necessary to condition and increase the voltage of electricity generated by Northern's Top of Iowa Wind Farm ("Wind Farm") to make it suitable for transmission on and to interconnect with the 161 Line and related and communications equipment and lines.

1.4 Phase II Substation. The "Phase II Substation" means future expansions or additions of equipment on the Substation Property to accommodate future electrical generating facilities perhaps including a future wind energy electric generating facility to be constructed in the area by NIW II commonly known as the "Top of Iowa Wind Farm Phase II" wind farm project and/or a generating facility using another energy source (collectively, "Future Generating Facilities") with a nameplate rating of not greater than 190 MW. The Phase II Substation will consist of all fencing, security devices, electrical lines, meters, monitoring equipment, switches, transformers, and other electrical and communications equipment necessary to condition and increase the voltage of electricity generated by the Future Generating Facilities to make it suitable for transmission on and to interconnect with the 161 Line.

1.5 Combined Substation. The Phase I Substation and Phase II Substation (if and when built) are sometimes, collectively, referred to as the "Combined Substation." Until (if ever) construction on the Phase II Substation begins, references to the Combined Substation shall be deemed to refer only to the Phase I Substation.

1.6

Purpose. The purpose of this Agreement is to grant all consents and reciprocal easements between Northern and NIW II necessary to allow:

1.6(a). Northern and IPL in its capacity as Northern's contractor to service the Phase I Substation including all reasonably necessary and appropriate access to the Phase 11 Substation (if and when built) and the Substation Property to fulfill its responsibilities under an Interconnection Agreement, dated July 9, 2001, between IPL and Northern ("Phase I Interconnection Agreement"), and to otherwise safely and efficiently operate and maintain the Phase I Substation in compliance with all applicable safety and regulatory requirements;

1.6(b). NIW II and IPL in its capacity as NIW II's contractor to service the Phase II Substation including all reasonably necessary and appropriate access to the Phase I Substation and the Substation Property to construct, operate and maintain the Phase II Substation on the Substation Property serving the Future Generating Facilities in accordance with this Agreement, future power purchase agreements between NIW II and its power purchasers, an Interconnection Agreement among Northern Iowa Windpower II, LLC, IPL and MISO dated November 24, 2003 ("Phase II Interconnection Agreement"), other future interconnection agreements involving NIW II, Midwest Renewable Energy Corporation and/or Midwest Renewable Energy Projects, LLC, their subsidiaries and successors in interest, and to otherwise safely and efficiently operate and maintain the Phase II Substation in compliance with all applicable safety and regulatory requirements.

2. GRANT OF NON-EXCLUSIVE ACCESS TO NIW II.

Subject to the terms and conditions of use set forth in this Agreement, Northern grants to NIW II non-exclusive access to connect to the Phase I Substation, to use the Phase I Substation, and to transmit energy generated by its Future Generating Facilities through the Phase I Substation to the interconnection point with the 161 line. This grant includes all access, transmission and communications easements, rights-of-way and any other easements and rights-of-way reasonably required in connection with such non-exclusive use of the Phase I Substation and for NIW II to develop, construct, connect to the existing Phase I Substation, operate, maintain, repair and remove the Phase 11 Substation on the Substation Property. The rights granted NIW II in this Agreement shall terminate January 1, 2008 if the Phase II Substation has not been constructed by that date. Once (if ever) the Phase II Substation is constructed, rights granted NIW II in this Agreement shall terminate on the three hundred sixty-fifth (365th) consecutive day that the Phase II Substation ceases to be used for electrical substation purposes if that date is earlier than the end of the Term indicated in Section 5 of this Agreement. Non-use of the Phase II Substation during reconstruction or re-powering of the Future Generating Facilities or the Phase II Substation shall not be deemed to be a cessation of use giving rise to termination pursuant to the preceding sentence. Upon termination as to the Phase II Substation, NIW II's obligations under this agreement shall also terminate, except for liabilities or obligations arising before the date of termination.

3.

SUBSTATION IMPROVEMENTS.

As a part of the access granted in the preceding section, NIW II shall have the right, at its sole cost and expense, to install (and connect to existing infrastructure in the Phase I Substation) a transformer in the Phase II Substation that shall at all times remain the sole property of NIW II. NIW 11 shall have the right, at its sole cost and expense, to construct improvements to the Phase II Substation that are necessary for its use of the Phase II Substation in connection with construction, testing, operation, maintenance and removal of its Future Generating Facilities. The design, engineering and other technical and operational aspects of the transformer and any and all improvements to the Phase II Substation shall be subject to prior written approval by Northern which shall not be unreasonably withheld or delayed. Northern shall respond to NIW II in writing to each request for approval as quickly as is commercially reasonable given the nature of the request, but in any event within thirty (30) days of receipt thereof. If the Phase I Substation shall be required to be out of service to accommodate implementation of the Phase II Substation, prior to any such out of service period, NIW II and Northern shall in good faith negotiate for a payment from NIW II to Northern that would reimburse Northern for any lost production from the Wind Farm. No work shall be done that would result in any out of service period until NIW II and Northern shall have agreed in writing to the amount or method for calculating such payment, which agreement shall not be unreasonably withheld or delayed.

4.

TERM AND REMOVAL OF SUBSTATION.

The term of this Agreement and of the consents and easements granted in it ("Term") shall begin upon signing of this Agreement by the parties and shall end on the first to occur of the following dates: (a) January 1, 2008 if N1W II has not by then constructed the Phase 11 Substation; (b) failure to pay the Granting Fee to Northern within the time allowed under Section 6; (c) termination pursuant to Section 2 for non-use of the Phase II Substation; and, (d) the three hundred sixty-fifth (365th) consecutive day (extended, if applicable, by Section 2) that all electrical generating facilities and their replacements using the Combined Substation or

Substation Property cease production of electricity. Northern and NIW II each shall have the express right, at any time and in its sole discretion, to remove any part of the Combined Substation it owns. If removal of any part of the Combined Substation will affect the safety or operation of equipment owned by any owner of the Phase I Substation or Phase II Substation, the party contemplating the equipment removal ("Withdrawing Party") shall consult with and obtain the prior written consent of the other party before conducting the contemplated removal. The party affected by the Withdrawing Party's equipment removal shall have the right to purchase any of such equipment to be removed at a fair market price to be determined by a third party expert chosen by the parties.

5.

CONDITIONS OF USE BY NIW H.

During the Term, NIW II shall (a) pay all amounts due to Northern under this Agreement, including, without limitation, fees as required in Section 6 of this Agreement, (b) maintain in good working order and repair at all times the Phase 11 Substation and those parts of the Phase II Substation, if ever constructed, wherever located on the Substation Property, that connect with or otherwise affect the Combined Substation, and (c) not interfere with the operation and maintenance of the Wind Farm in any manner. NIW II shall not change, use or modify the Combined Substation so as to prevent or interfere with Northern's use of the Combined Substation or the energy production of the Wind Farm. NIW 11 shall be free to carry out its business activities in its sole discretion, which shall not conflict with Northern's access and use of the Combined Substation.

If either NIW II or Northern experiences operating difficulties with any portion of its generation facilities, after interconnection of the Future Generating Facilities with the Combined Substation, as to which there is a dispute between the parties about what is causing such difficulties, the parties shall as quickly as possible implement a solution (permanent or temporary) that will minimize total lost revenues or damage. Thereafter, NIW 11 and Northern shall promptly determine the cause of the difficulties, using if necessary the services of appropriate third party experts, and the party found to have caused the difficulty shall reimburse the other for lost revenue and reasonable out of pocket expenses incurred to investigate, mitigate and cure such difficulties.

NIW 11 and Northern agree that the existing Phase I Substation is adequate for meeting the needs and requirements of Northern to export its power production and deliver to its buyers of power. The activities or contracts of NIW II shall in no way inhibit or limit Northern's ability to sell and deliver power into the transmission system. If transmission constraints exist at a time when Northern enters into new or amended sales contracts, then the parties shall have such rights to move the electricity generated by the Wind Farm and the Future Generating Facilities as would exist if they were served by separate substations connected to the 161 Line located within two miles the Substation.

Within ninety (90) days after it executes a power purchase agreement or agreements providing for sale of all of the power to be generated by the Future Generating Facilities, but in no event later than January 1, 2008, NIW II shall pay Northern a one time fee (the "Granting Fee") in the amount of Five Hundred Thousand Dollars ($500,000). Notwithstanding any provision herein to the contrary, if NIW II does not complete the installation of the Phase 11 substation and elects to allow this Agreement to terminate, then NIW II shall not owe any Granting Fee, operating, or maintenance expenses.

During the Term, but with NIW H's financial obligation beginning upon completion of the Phase II Substation, Northern and NIW H shall share equally the operating and maintenance expenses (including, without limitation, replacement or repair costs, but specifically excluding such operating and maintenance expenses with respect to the transformers of each of the Wind Farm and the Future Generating Facilities which shall be the sole obligation of Northern and NIW II, respectively) of the Combined Substation ("Necessary Expenses"). Northern or NIW II shall each have the right, but not the duty, to advance payment in full any Necessary Expenses and the other party, within thirty (30) days after receipt of a statement for the expenses thus advanced, shall reimburse the party making the advance an amount equal to fifty percent (50%) of the total amount advanced.

12.3

New Agreement.

12.3(a) If this Agreement terminates because of Northern or NIW II's default, if the rights granted in this Agreement are foreclosed, or if this Agreement is rejected or disaffirmed pursuant to bankruptcy law or other law affecting creditor's rights and, within ninety (90) days after such event, Northern, NIW II or any Mortgagee or Assignee shall have arranged to the reasonable satisfaction of the non-defaulting party for the payment of all fees or other charges due and payable by Northern or NIW II as of the date of such event, then such non-defaulting party shall execute and deliver to Northern, NIW II or such Mortgagee or Assignee or to a designee of one of these parties, as the case may be, a new agreement affecting the Substation Property which (i) shall be for a term equal to the remainder of the Term before giving effect to such rejection or termination; (ii) shall contain the same covenants, agreements, terms, provisions and limitations as this Agreement (except for any requirements that have been fulfilled by Northern, NIW II or any Mortgagee or Assignee prior to rejection or termination of this Agreement); and, (iii) shall include that portion of the Wind Farm Assets in which Northern, NIW II or such other Mortgagee or Assignee had an interest on the date of rejection or termination.

12.3(b) After the termination, rejection or disaffirmation of this Agreement and during the period thereafter during which any Mortgagee shall be entitled to enter into a new agreement affecting the Substation Property, the non-defaulting party will not terminate the rights of any Assignee unless in default under its Assignment.

12.3(c) If more than one Mortgagee makes a written request for a new agreement pursuant to this provision, the new agreement shall be delivered to the Mortgagee requesting such new agreement whose Mortgage is prior in lien, and the written request of any other Mortgagee whose lien is subordinate shall be void and of no further force or effect.

12.3(d) The provisions of this Section 12 shall survive the termination, rejection or disaffirmation of this Agreement and shall continue in full force and effect thereafter to the same extent as if this Section 12 were a separate and independent contract made by Northern, NIW Il and each Mortgagee, and, from the effective date of such termination, rejection or disaffirmation of this Agreement to the date of execution and delivery of such new agreement, such Mortgagee may use and enjoy the Substation Property without hindrance by the non-defaulting party or any person claiming by, through or under either of them; provided that all of the conditions for the new agreement as set forth above are complied with.

12.3(e) The party requesting or receiving the new agreement shall pay the non-defaulting party's reasonable legal fees and other out of pocket expenses related to preparation, review, execution and delivery of the new agreement.

This provision is for the express benefit of and shall be enforceable by each Mortgagee as if it were a party named in this Agreement.

 12.5 No Merger. There shall be no merger of this Agreement or of the rights created under this Agreement with the fee estate in the Substation Property by reason of the fact that this Agreement or any interest in this Agreement may be held, directly or indirectly, by or for the

account of any person or persons who shall own any interest in the fee estate. No merger shall occur unless and until all persons at the time having an interest in the fee estate in the Substation Property and all persons (including each Mortgagee) having an interest in this Agreement or in the estate of Northern or NIW II shall sign and record a written instrument effecting such merger.

12.6 Further Amendments. At Northern's or NIW II's request, the other party shall amend this Agreement to include any provision which may reasonably be requested by a proposed Mortgagee; provided, however, that such amendment does not impair any of such party's rights under this Agreement or increase the burdens, liabilities or obligations of such party under this Agreement. Upon the request of any Mortgagee, Northern and NIW II shall execute any additional instruments reasonably required to evidence such Mortgagee's rights under this. Agreement. The party who requests such amendments shall pay the reasonable expenses of the other parties to negotiate and review such requested amendments, or such costs may be shared as the parties may otherwise agree.

15.

MISCELLANEOUS.

15.1 Unavoidable Delays.

The affected party shall use its reasonable efforts to avoid or remove the causes of nonperformance and shall continue performance whenever the causes for nonperformance are removed.

15.2 Run With the Land.

Should any provision of this Agreement be held, in a final and unappealable decision by a court of competent jurisdiction, to be either invalid, void or unenforceable, the remaining provisions of this Agreement shall remain in full force and effect, unimpaired by the holding. Notwithstanding any other provision of this Agreement, the parties agree that in no event shall the Term be for longer periods than the longest periods permitted by applicable law.

15.7 Tax Credits. If under applicable law one of the parties becomes ineligible for any tax credit, benefit or incentive for alternative energy expenditure established by any local, state or federal government, then, at requesting party's option and expense, the remaining parties shall amend this Agreement or replace it with a different instrument so as to convert the requesting party's interest in the Substation Property to a substantially similar interest that makes it eligible for such tax credit, benefit or incentive. No party shall be required to perform under this Section if it will cause that party financial detriment, interfere with its business activities or would result in a breach of any obligation under any agreement to which it is a party.

15.8 Approvals. No approval required by this Agreement shall be unreasonably delayed. Unless a longer or shorter time is specified, all approvals required of either party shall be given or refused in writing within ten (10) business days after receipt of the request for approval.
