(b)

The Term shall consist of the Development Period, the Production Period and the Post-Production Period.

(c)

The “Development Period” shall commence on the Effective Date and shall terminate the Day prior to the commencement of the Production Period.

(d)

The “Production Period” shall commence on the date on which Seller makes initial deliveries of lignite from the Mine (the “Production Date”), which is expected to occur on May 5, 2016, and shall terminate on December 31, 2040, unless extended pursuant to Section 2.1(f) or terminated earlier in accordance with the other provisions of this Agreement.

(e)

The “Post-Production Period” shall commence when mining and delivery of lignite from the Mine permanently ceases and shall continue until the Mine reclamation bond is released to Seller by the North Dakota Public Service Commission.

-7-

(f)

The Production Period shall automatically extend for successive five-year periods until exhaustion of Seller’s lignite in the Reserves, unless notice of the desire not to extend the Production Period is given by either Buyer or Seller not less than six months prior to the expiration of the original or any extended Production Period then in effect.

2.2

Communication Regarding the Production Date

Seller anticipates that the period necessary to complete the permitting of the Mine is [**]. During the Development Period, Buyer and Seller shall meet not less than one time each calendar quarter to discuss the date on which Seller anticipates receiving the Mine permit. In the event that Seller does not anticipate it will receive the Mine permit [**], Seller shall notify Buyer of the anticipated Production Date in writing as soon as possible and not later than [**]. Such notice shall set forth the date on which Seller anticipates, based on information then reasonably available, the Production Date will occur. In such event, Seller and Buyer shall promptly use their collective reasonable best efforts to secure replacement fuel meeting the Quality Requirements in accordance with Section 2.9(c), in the quantity necessary to meet the Plant’s fuel requirements between May 5, 2016 and the anticipated Production Date set forth in Seller’s written notice to Buyer. Seller shall pay a portion of the cost of such replacement fuel under the circumstances contemplated by, and to the extent required by, Section 2.9(c). Buyer shall pay such cost if Seller is not obligated to do so pursuant to Section 2.9(c).

2.3

Sale and Purchase of Lignite

During the Production Period, Buyer hereby agrees to purchase and accept exclusively from Seller, and Seller hereby agrees to sell and deliver to Buyer, for the Compensation and upon the other terms and conditions hereinafter set forth, quantities of lignite from the Mine equal to the Plant’s fuel requirements as set forth in Section 2.5. In no event shall Buyer purchase or use any fuel for the Plant that is not produced at the Mine unless such purchase is made in accordance with Section 2.9. For the avoidance of doubt, this Agreement is an all requirements contract subject to the limitations set forth in Article 2-306 of the Uniform Commercial Code (N.D. Cent. Code § 41-02-23).

The foregoing dedication is a dedication of quantity and not a dedication of specific reserves within the Reserves.

[**]	Represents text deleted pursuant to a confidentiality treatment request filed with the Securities and Exchange Commission pursuant to Rule 24b-2 under the Securities Exchange Act of 1934, as amended

-8-

Seller intends to sublease the Reserves within the South Beulah Area of Interest from NACoal. Seller shall include in each such sublease a clause whereby Seller dedicates from the Reserves the quantity of lignite that is sufficient for the performance of Seller’s obligations under, and in accordance with, this Agreement. Seller shall record each such sublease in the official records of ▇▇▇▇▇▇ County, North Dakota.

2.4.2 Nothing in this Section 2.4 or any other section or exhibit of this Agreement:

(a)

is intended to, or shall be interpreted or construed to, constitute a sale, transfer, assignment or other conveyance, or an agreement to enter into any of the foregoing, of any Reserves or of any underlying leases or subleases of Reserves by Seller;

(b)

shall be construed as preventing Seller from making ▇▇▇▇▇▇▇ Sales pursuant to Section 14.2 or from mining and selling lignite from the Reserves to third parties as set forth in Section 14.3; or

(c)

shall be construed as preventing Buyer from selling lignite purchased from Seller and owned by Buyer to third parties as set forth in Section 14.5.

2.5

Quantity

The annual quantity of lignite to be sold and delivered by Seller to Buyer from the Reserves shall be the quantity required for (a) all of the Plant’s fuel requirements (except to the extent alternate fuel is used in accordance with Section 2.9) and (b) Buyer to make sales of lignite to third parties as permitted in Section 14.5. If any increase in Buyer’s lignite requirements for the Plant necessitates the acquisition by Seller of additional equipment, the hiring and training of additional employees or the acquisition of additional lignite reserves, Seller shall not be obligated to supply such increased lignite requirements until it is able to acquire and install such additional equipment, hire and train such additional employees, acquire such additional lignite reserves and do all other things necessary to supply such increased lignite requirements. If any long-term decrease in the Plant’s fuel requirements occurs, Seller shall use reasonable best efforts to reduce costs in a manner reasonably commensurate with the reduced Plant fuel requirements.

2.6

Designation of Deliveries

2.6.1 No later than April 1 of each Year during the Term, Buyer shall notify Seller in writing of the number of Tons of lignite that Buyer will require from the Mine at the Delivery Point during the subsequent Year on a Monthly basis (the “Delivery Year Nomination”), and an estimate of the quantity of Tons of lignite which Buyer estimates it will request Seller to deliver to the Delivery Point during each of the four subsequent Years.

2.6.2 At any time and from time to time, Buyer shall have the right, upon notice to Seller, to increase or to decrease any previously issued Delivery Year Nomination to the extent desired by Buyer, subject, however, to the limitations set forth in Section 2.5.

2.7

Rate of Delivery

The delivery of lignite to the Delivery Point shall be made in Monthly quantities that approximate the Monthly lignite requirements designated by Buyer pursuant to Section 2.6, or as otherwise directed by Buyer, subject, however, to the limitations set forth in Section 2.5.

-9-

2.8

Stockpile Inventories

Buyer and Seller shall mutually agree on the types, sizes and locations of lignite stockpiles to be maintained at the Mine and, if necessary, the Plant. It is expected that the aggregate amount of lignite in the Mine and any Plant stockpiles ordinarily will not be less than 200,000 Tons. Buyer shall have the right to require Seller to increase or decrease the size of the stockpiles or to change the Delivery Point, subject to (a) the limitations set forth in Section 2.5, (b) the then-current Annual Mining Plan and (c) the then-current mining conditions.

2.9

Permitted Alternate Fuel

Without limiting the all-requirements nature of this Agreement, Buyer shall have the right to purchase fuel for the Plant other than Seller’s lignite in the following limited circumstances:

(a)

Buyer may burn fuel oil (i) to aid in Plant start-up and (ii) to increase Btus in the event that the lignite delivered by Seller does not contain enough Btus to operate the Plant’s existing cyclone boiler;

(b)

Buyer may purchase alternate fuel for the Plant to the extent necessary to replace any lignite not delivered by Seller due to and during the continuance of (i) a Force Majeure event impacting Seller, (ii) a Governmental Order to the extent it forecloses Buyer from purchasing and utilizing Seller’s lignite at the Plant or (iii) a Seller Default, and in each case for no longer and to no greater extent;

(c)

If (i) the Production Date has not occurred by May 5, 2016 (for reasons not attributable to Buyer and not attributable to a Force Majeure affecting Seller) and (ii) Buyer’s existing stockpile on the Plant site is exhausted, Seller shall use reasonable best efforts to provide replacement fuel meeting the Quality Requirements until the Production Date occurs. In the event that Seller provides replacement fuel pursuant to the preceding sentence, Buyer shall pay to Seller for each 13,424,000 Btus of replacement fuel1 delivered an amount equal to the sum of (A) the estimated Cost of Production per Ton (as reflected in the then-current Annual Mining Plan) and (B) the Agreed Profit per Ton, and Seller shall pay the supplier of such replacement fuel for such replacement fuel. To the extent that Seller does not so provide replacement fuel, Buyer may purchase a quantity of alternate fuel that Buyer reasonably anticipates will be sufficient to fuel the Plant until the Production Date at the lowest cost available to Buyer (and for no longer and to no greater extent). In the event that Buyer provides replacement fuel pursuant to the preceding sentence, Seller shall pay to Buyer for each 13,424,000 Btus of replacement fuel so provided the difference between (X) Buyer’s actual cost therefor and (Y) the sum of (1) the estimated Cost of Production per Ton (as reflected in the then-current Annual Mining Plan) and (2) the Agreed Profit per Ton; or

1 13,424,000 Btus is the Btu equivalent of one Ton of lignite with a heat value of 6,712 Btus/lb. (2,000 x 6,712).

-10-

(d)

In accordance with the terms of any prior written consent of Seller to such purchase by Buyer, potentially including fuel blending by Buyer to prevent a fuel switch due to a Governmental Order.

2.10

Chemical Additives to Lignite

Buyer may add chemical additives to the lignite sold hereunder for the purpose of (a) improving the Plant’s compliance with Applicable Laws regulating emissions from the Plant or (b) generating or participating in the generation of federal income tax credits under the Internal Revenue Code.

Lignite Description

The lignite to be sold and delivered hereunder shall be from the Mine and shall be crushed Run-of-Mine Lignite having a top size of nominal three inch minus or such larger size as Buyer may specify in a notice to Seller. Seller shall deliver the lignite so as to be reasonably free from contaminants, including, but not limited to, rock, bone, slate, earth, pyrite, wood, metal and mine debris.

3.2

Annual Quality

Seller shall furnish to Buyer a projection of the quality of the lignite to be mined and delivered to Buyer each Year based on quality data which is available to Seller relating to Reserves within the South ▇▇▇▇▇▇ Area of Interest. Periodically, or at the request of Buyer, the Parties shall meet to discuss the quality of delivered lignite.

3.3

Minimum Lignite Quality Standards

In the event that the delivered quality of lignite in any Sampling Period, on an As-Delivered, As-Received basis, is below any minimum specification or above any maximum specification listed below (the “Quality Requirements”):

Specification	Minimum	Maximum

Calorific value, Btu/lb	6,500	N/A
Moisture, % by weight	N/A	40%
Ash, % by weight	4%	13%
Sulfur, % by weight	N/A	1.3%
Sodium (in ash), % by weight	N/A	8%

then the lignite delivered during such Sampling Period shall constitute “Non-conforming Lignite.”

WARRANTY AS TO LIGNITE SOLD HEREUNDER AS A GOOD: EXCEPT THAT THE LIGNITE SHALL MEET THE FOREGOING QUALITY REQUIREMENTS, SELLER MAKES NO, AND HEREBY DISCLAIMS ALL, WARRANTIES RELATED TO THE LIGNITE DELIVERED HEREUNDER, INCLUDING, WITHOUT LIMITATION, THE WARRANTIES OF FITNESS FOR A PARTICULAR PURPOSE AND MERCHANTABILITY.

3.4

Non-conforming Lignite

Buyer shall have the option to accept delivery of Non-conforming Lignite. Regardless of whether Buyer accepts delivery of such Non-conforming Lignite, Buyer shall compensate Seller for such Non-conforming Lignite in an amount equal to the Compensation minus the Agreed Profit for such Non-conforming Lignite. Except as provided in the last sentence of Section 15.1, the elimination of the Agreed Profit on Non-conforming Lignite is Buyer’s sole and exclusive remedy with respect to the delivery of Non-conforming Lignite by Seller.

Section 4.

Delivery Point; Title and Risk of Loss

The lignite from the Mine for use at the Plant shall be delivered by Seller to Buyer at the terminus of Seller’s conveyor to the Plant, or at such other point or place mutually agreed to by Buyer and Seller (the “Delivery Point”). Lignite shall be deemed to have been sold and delivered to Buyer, and title and risk of loss or damage thereto shall pass to Buyer, upon delivery of such lignite at the Delivery Point.

Section 5.

Mining Plans

5.2.1 Life-of-Mine Plan

(a)

Seller shall prepare and provide to Buyer in writing a mining plan covering the life-of-mine requirements (the “Life-of-Mine Plan”) for the design, development, construction, start-up and operation of the Mine, including the Development Period, the Production Period and the Post-Production Period to furnish from the Reserves the lignite requirements of Buyer under this Agreement. Seller’s initial Life-of-Mine Plan shall assume that Buyer’s life-of-mine lignite requirements shall be equal to 2,500,000 Tons per Year unless Buyer notifies Seller to use a different assumption. The Life-of-Mine Plan shall be based on the principle of recovering the most economic reserves from within the Reserves over the Term. The Life-of-Mine Plan shall be prepared in accordance with sound engineering and design practices and Applicable Laws and shall include, but not be limited to, production schedules, staffing and equipment requirements, estimated costs per Ton using the cost categories identified in Section 7, a property acquisition plan, schedule and estimated budget, a mine development plan, schedule and budget, method of operation, anticipated lignite quality characteristics, reclamation and permitting schedules, estimated capital budget containing estimates of all capital expenditures, commitments, and loan/lease requirements, operating cost estimates, mine design, mine projection maps, mine progression and reserve studies, and other documentation reasonably requested by Buyer. Seller will permit Buyer’s representatives to participate in the development of the Life-of-Mine Plan and any revisions thereto.

-13-

(b)

The Life-of-Mine Plan shall be completed and delivered by Seller to Buyer within three hundred sixty-five (365) Days of the Effective Date. Buyer shall review the Life-of-Mine Plan for reasonableness and completeness.

(b)

If Buyer does not give Seller such notice within sixty (60) Days after Buyer’s receipt thereof, Buyer shall be deemed to have approved such mining plan(s).

(c)

If Buyer disapproves an Annual Mining Plan or any portion(s) thereof, Buyer shall advise Seller of the reasons for such disapproval, and Buyer and Seller shall meet promptly, but no more than ten (10) Business Days after such disapproval was expressed, and attempt in good faith to resolve their differences with respect to the Annual Mining Plan. If Buyer and Seller are unable to resolve such differences within such ten (10) Business Days, Seller shall adopt such changes to the Annual Mining Plan as requested by Buyer, and shall submit a revised Annual Mining Plan within ten (10) Business Days following the failure of Buyer and Seller to resolve such differences.

5.2.4 Mine Development and Operation

(a)

Seller shall consult with and keep Buyer informed of the progress of Seller’s activities related to the Mine during the Term in such manner as Buyer may reasonably request.

(b)

Buyer and Seller shall meet quarterly (or at such other times as needed or requested by either Party) to review the progress of Seller’s activities related to the Mine during the Term.

-15-

(c)

Seller shall not make any capital expenditures unless they are generally reflected in a capital budget approved by Buyer as part of an Annual Mining Plan or unless otherwise specifically approved by Buyer; provided, however, Seller shall have the right during any Year to make capital expenditures required in the event of an Emergency without advance approval by Buyer. If the nature of the Emergency and the time elements involved do not allow sufficient time to obtain Buyer’s approval of such capital expenditure before it is incurred, Seller shall subsequently and promptly (but not later than two Business Days after such occurrence) give Buyer notice thereof.

(d)

Seller shall have the right, without the specific written approval of Buyer, to exceed the amount for any specific capital expenditure in any budget approved by Buyer by up to five percent (5%), provided that in no event shall any such excess expenditure exceed One Hundred Thousand Dollars ($100,000) (the “CapX Cap”) (subject to adjustment pursuant to Section 9) or such other amount as mutually agreed to by the Parties in any Year. If Seller desires Buyer’s approval to exceed a specific line item, budgeted, capital expenditure by more than five percent (5%) or more than the CapX Cap or such other amount as mutually agreed to by the Parties in any Year, Seller shall make such request by written notice as soon as practicable, and if Buyer neither approves nor disapproves such request within fifteen (15) Business Days after Seller’s delivery thereof, Buyer shall be deemed to have approved such request.

(e)

Except in the event of an Emergency, no material modification of or material deviation from the approved Annual Mining Plan shall be made without the written approval of Buyer, which approval shall not be unreasonably withheld.

5.3

Post-Mining Reclamation

5.3.1 Commencing with the issuance of the Mine permit (and thereafter at least as frequently as required by GAAP), Seller shall prepare in accordance with GAAP an estimate of all costs and expenses that will be incurred to finally reclaim and close the Mine in order to obtain the release of the reclamation bond from the North Dakota Public Service Commission (the “Post-Mining Reclamation Costs”), and the Parties shall mutually agree on the appropriate assumptions underlying the accrual of such costs and their inclusion in the Cost of Production under Section 7.2(a).

5.3.2 When requested by Buyer, but no less frequently than five Years after the commencement of the Production Period and every five Years thereafter, Seller shall submit to Buyer for its review and written approval proposed plans and estimated budgets for final reclamation activities during the Post-Production Period. Buyer shall not unreasonably withhold its approval of such plans and budgets as long as Seller utilizes generally accepted reclamation practices in preparing such plans and budgets. After Buyer’s written approval of such plans and budgets (or portions thereof), Seller shall seek Buyer’s prior written approval of any material changes to or from such final reclamation plans and budgets. Seller shall submit such reports regarding Seller’s activities and reclamation costs incurred as Buyer may request from time to time during the Post-Production Period.

-16-

5.3.3 Within ten Days of receipt from Buyer, Seller shall deposit all amounts for Post-Mining Reclamation Costs funded by Buyer pursuant to Section 7.2(a), or funded by Seller pursuant to Section 14.4 (third-party sales), in a trust account (the “Reclamation Account”) to be managed by a trustee to be proposed by Seller and approved by Buyer, in accordance with the North Dakota version of The Uniform Prudent Investor Act, as may be amended from time to time. Funds held in the Reclamation Account shall only be disbursed by the trustee upon receipt of a joint written disbursement instruction by Buyer and Seller and shall only be expended during the Post-Production Period to complete final Mine closure and reclamation; provided, however, that to the extent Buyer and Seller mutually agree that the Reclamation Account is over-funded from time-to-time, Buyer and Seller may mutually direct the Reclamation Account trustee to distribute the excess amount to the agent under the Plant Ownership Agreement for distribution to the Utilities. Seller and Buyer shall meet at least one time each Year during the Production Period and the Post-Production Period to discuss such account and any expenditures therefrom, and review related account statements and documents (“Reclamation Account Documentation”). Buyer shall have the right to inspect Reclamation Account Documentation as provided in Section 12.3(a).

5.4

Operating Contracts

Seller may determine that it is appropriate to enter into contracts with third parties to provide services to Seller in connection with performance of Seller’s obligations hereunder (“Operating Contracts”). Seller’s entry into any such Operating Contracts shall not relieve Seller of any of its obligations hereunder. All Operating Contracts shall provide that the third party that is performing services, and any party that may acquire Seller, may not terminate the Operating Contract in the event of a change-in-control of Seller. Seller shall provide Buyer reasonable advance notice in the event Seller intends to enter into an Operating Contract with total consideration to the third party thereto in excess of $1,000,000 (the “Operating Contract Threshold”) or a term in excess of twenty-four (24) months. Buyer shall have the opportunity to review and comment on such Operating Contracts prior to Seller’s execution thereof, and shall provide comments as promptly as reasonably practicable, taking into consideration Seller’s obligation to timely perform Seller’s obligations hereunder.

Section 6.

Financial Arrangements

6.1

Seller Responsible for Mine Financial Arrangements

Seller shall be responsible throughout the Term, for securing loans, leases, extensions of credit and other financial arrangements (“Seller’s Loans and Leases”) for Working Capital and capital assets including, without limitation, machinery, equipment (including one or more draglines), fixtures, fee lands upon which fixtures are located, roads, ponds, electric utility lines, water and gas pipelines and easements for all such lines and pipelines (“Capital Assets”) necessary for, but not limited to, the design, development, permitting, construction, equipping, start-up, operation, maintenance and reclamation of the Mine to the capacity required for producing the quantities of lignite to be purchased from Seller under this Agreement. Seller shall use reasonable best efforts to obtain the lowest cost Seller’s Loans and Leases that are available to Seller, and to include in the Seller’s Loans and Leases a lessee right to buyout or terminate prior to the end of the term of Seller’s Loans and Leases. Seller shall use its reasonable best efforts to structure the payment terms of Seller Loan and Lease Principal Obligations under the Seller’s Loans and Leases used to fund the original purchase of Capital Assets to correspond approximately with the depreciation or amortization expensed during the estimated useful life of Capital Assets. Seller’s obligations under this Section 6.1 in respect of Capital Assets shall terminate in the event that Buyer acquires all of the Capital Assets. For the avoidance of doubt, Seller’s or Seller’s Affiliate’s acquisition and financing costs related to its ▇▇▇▇▇▇ 8400 walking dragline, from its date of acquisition on May 21, 2012 (the “Pre-LSA Dragline Costs”), shall be deemed a Seller Loan and Lease.

-17-

6.2

Buyer’s Right to Replace Seller’s Loans and Leases

6.2.1 At any time, Buyer shall have the right to acquire all of Seller’s Capital Assets and obtain alternative arrangements to replace all of Seller’s Loans and Leases.

6.2.2 In order to exercise such right, Buyer shall give notice to Seller of Buyer’s election to acquire the Capital Assets and pay to Seller the Net Book Value of such Capital Assets. Seller shall use any necessary portion of such Buyer payment (including up to, but not exceeding, the full amount thereof) to discharge Seller’s Loan and Lease Principal Obligations and Seller’s Loan and Lease Obligations applicable to such Capital Assets. If any amount of Seller’s Loan and Lease Principal Obligations or Seller’s Loan and Lease Obligations (other than with respect to Working Capital) remain after such payment by Seller, then Buyer shall directly pay to the lender the remaining Seller’s Loan and Lease Principal Obligations, and shall reimburse to Seller promptly (after receiving proof of payment by Seller) all remaining Seller’s Loan and Lease Obligations (other than with respect to Working Capital) arising as a result of such acquisition. The Parties agree to execute and deliver such documents and instruments as may be reasonably necessary or appropriate to vest in Buyer Seller’s title to the Capital Assets, to release and hold harmless Seller and any of Seller’s Affiliates from all liability relating to all Seller’s Loan and Lease Principal Obligations applicable to such Capital Assets and to ensure Seller’s reimbursement for Seller’s Loan and Lease Obligations applicable to such Capital Assets. In the event Buyer so acquires the Capital Assets, Buyer shall provide Seller and its Affiliates with access to and use of the Capital Assets acquired by Buyer as reasonably necessary for Seller to perform its obligations under this Agreement and, at Seller’s request, Buyer shall execute and deliver licenses or other agreements containing terms and conditions mutually acceptable to Buyer and Seller confirming such Seller right of access and use.

6.2.3 If Buyer exercises its right to acquire all of Seller’s Capital Assets pursuant to this Section 6.2, Seller shall have the right to contribute its Capital Assets to a wholly-owned subsidiary of Seller or NACoal and cause Buyer to acquire the equity of such subsidiary pursuant to the terms and conditions of a purchase and sale agreement for the equity interests of such subsidiary for a purchase price equal to the Net Book Value of the Capital Assets contributed to the subsidiary and on other terms to be agreed by the Parties. In such event, the purchase and sale agreement shall include amendments to this Agreement referred to in Section 22.13 to reflect that all of the Mine’s Capital Assets are no longer owned by Seller, and that Buyer thereafter has the responsibilities in respect of Capital Assets set forth in the first sentence of Section 6.1.

Section 9.

Adjustment of Adjustable Amounts

The CapX Cap, the Development Fee, the Agreed Profit, the Cap Amounts and the Operating Contract Threshold (the “Adjustable Amounts”) are expressed in 2011 dollars and are subject to adjustment as follows:

(a)

Beginning on April 1, 2013, the Adjustable Amounts shall be increased or decreased, as appropriate, as of January 1, April 1, July 1 and October 1 of each Year in the same percentage by which (x) the first published value of the CPI-U Index for the third Month immediately preceding such January 1, April 1, July 1 or October 1 under consideration is greater or less than (y) the first published value of the CPI-U Index for June 2011 (which is 225.722, on the base 1982-1984 = 100). Such increased or decreased Adjustable Amounts shall be effective as of such January 1, April 1, July 1 or October 1 adjustment date and shall be included in the next Monthly invoice following such adjustment date, and any additional payment to be made by Buyer or refund to be made by Seller shall be made accordingly. An example calculation of such year-end adjustment is set forth in Exhibit C. If any adjustment made pursuant to this Section 9(a) is based upon a first published CPI-U Index figure that is subsequently revised, there shall be no further adjustment of such amount on the basis of such revision.

(b)

If at any time during the Term either Party reasonably believes that the CPI-U Index (or any index substituted therefor in accordance with the following provisions) does not reflect the true change in the price level of consumer goods and services in the United States, then upon the written request of either Party, Buyer and Seller shall undertake good faith negotiations to determine and agree upon a substitute index or method whereby such change in the price level of consumer goods and services in the United States can be determined. When and if such substituted index or method has been determined and mutually agreed upon, the same shall be substituted and put into effect commencing at a time mutually agreed upon by Seller and Buyer. If the CPI-U Index or any substitute index is changed in the future to use some base other than the base of 1982-1984 = 100, for the purposes hereof, the CPI-U Index or any substitute index, as the case may be, shall be adjusted so as to be in correct relationship to the base of 1982-1984 = 100, or some other alternative base which is mutually agreed by Buyer and Seller. If publication of the CPI-U Index or any substitute index is no longer made by any United States agency, the index to be used shall be that index agreed to by the Parties which after any necessary adjustment provides the most reasonable substitute for the CPI-U Index. If within ninety (90) Days the Parties cannot agree upon a substitute index, the matter shall be resolved by arbitration pursuant to Section 18.

Section 11.

Sampling and Analysis; Weights

11.1

Sampling and Analysis

11.1.1 All sampling, sample preparation and analysis of lignite shall be performed in accordance with this Section 11. The quality of lignite delivered by Seller to Buyer shall be determined by analyses of samples taken by Buyer once Daily (each Day, a “Sampling Period”) at a time and a location mutually agreed to by the Parties, which time and location shall be intended to result in samples that are fairly representative of the lignite delivered during the Day in which the samples are taken. Buyer shall collect representative samples by means of a mechanical belt sampling system to be operated and maintained by Buyer (the “Sampling System”).

11.1.2 The design and operation of the Sampling System and the procedures used for sample preparation shall meet standards to be mutually agreed to by the Parties. The Sampling System shall be enclosed to minimize moisture loss. If necessary due to the design and operating standards agreed by the Parties, Buyer and Seller shall mutually agree on commercially reasonable modifications of Plant and Mine procedures and equipment.

11.1.3 All sample increments collected shall be designed to cut the full stream of lignite presented during the period in which such sample increments are collected. The values of current measurements of Sampling System cutter openings, cutter frequencies, cutter velocities, belt velocities and sample flow rates shall be made available by Buyer to Seller upon request and shall be reasonably acceptable to Seller.

-29-

11.1.4 Buyer shall monitor the sampling ratio of the Sampling System in accordance with standards mutually agreed to by the Parties. Buyer shall make the sampling ratio data available to Seller upon request.

11.1.5 Prior to any modification to the Sampling System, Buyer shall submit design drawings, specifications and sample extraction parameters for the new or modified Sampling System to Seller for its approval, which shall not be unreasonably withheld.

11.1.6 In the event that the Sampling System ceases to operate properly, Buyer shall immediately notify Seller of such cessation and Buyer’s intended course of action to remedy such cessation as soon as reasonably practicable. If the Sampling System malfunctions during the delivery of lignite under this Agreement, the weighted average of the sample analyses successfully taken during the previous seven consecutive Sampling Periods when the Sampling System was properly operating shall be used for those Sampling Periods where the Sampling System was not properly operating.

11.1.7 Using an enclosed ▇▇▇▇▇▇ and following the mutually agreed ASTM standards, Buyer shall divide the sample size into two laboratory sample splits, with each weighing a minimum of 2,000 grams. Each sample split shall be placed in suitable airtight containers and used as follows:

(a)

Buyer shall cause split one to be transported to and analyzed by a laboratory designated by Buyer.

(b)

Split two of each sample shall be used for referee purposes. If referee analysis is required, the referee’s expenses shall be borne by the Party calling for the referee sample.

(c)

Split two of each sample shall be properly identified and stored by Buyer for a period of not less than one Month after the receipt of the analytical results of split one.

11.1.8 For lignite deliveries for which a sample is not available or for which a sample is agreed by Buyer and Seller to be incorrect, the weighted average of the sample analyses successfully taken during the previous seven Sampling Periods when the Sampling System was properly operating shall be utilized.

11.1.9 All third-party analyses of lignite samples shall be in accordance with the mutually agreed ASTM standards. The designated laboratory shall also participate in round-▇▇▇▇▇ testing of lignite coals with other laboratories to verify its sample preparation and analysis procedures. Buyer or Seller may also, from time to time, submit blind samples to the designated laboratory for analysis and verification of accuracy and repeatability at the sole cost of the submitting Party. If the round-▇▇▇▇▇ testing or blind samples of lignite indicate that the analytic results of the designated laboratory are inconsistent with or do not conform to ASTM repeatability standards, the Parties shall designate another laboratory mutually agreed to by the Parties.

-30-

11.2

Analytical Results

The laboratory analyzing any sample shall electronically deliver the results of its analysis simultaneously to both Buyer and Seller. The results of the analyses performed by the designated laboratory on split one of the samples shall be binding on the Parties and shall be deemed to represent the quality of the lignite delivered hereunder, unless one Party notifies the other in writing of a dispute concerning such analysis within thirty (30) Business Days after receipt of the designated laboratory’s analysis of split one. If the analysis of split one is disputed, split two shall be analyzed and the quality characteristics of split two shall be deemed to represent the definitive quality characteristics of the lignite delivered during the Sampling Period covered by splits one and two.

11.3

Weighing

(a)

The weight of the lignite delivered to Buyer from the Mine shall be determined on scales utilized by Buyer at the Plant site on the Effective Date. If Buyer elects to replace its existing scale, Buyer and Seller shall mutually agree to the design, selection and installation of the replacement scale(s).

(b)

The scales shall be maintained and calibrated in accordance with the manufacturer’s recommended standards, and shall be calibrated on a regular basis agreed by the Parties and maintained within design tolerance. Each Party shall have the right to have a representative present at any and all times to observe the testing and calibration of the scale(s).

(c)

Seller shall have the right to install a check scale on Buyer’s conveyor belt(s) at Seller’s expense and, if Seller so installs a check scale, Seller shall be obligated to operate, maintain and calibrate such check scale in accordance with the manufacturer’s recommendations and otherwise as agreed by the Parties.

(d)

The weights determined pursuant to Section 11.3(a) shall be used to determine the total Tons of lignite delivered each Month under this Agreement. The total Tons of lignite delivered to Buyer each Month so determined shall be accepted as the quantity of lignite for which invoices are to be rendered and payments made in accordance with Section 8.

(e)

Seller shall be given a record of all weight determinations made by Buyer. Buyer shall perform an initial materials weight test within one Year of the Production Date and thereafter shall perform materials weight tests at least every five Years, and shall directly pay the costs thereof. If either Party at any time questions the accuracy of the scales, such Party may request a prompt test and adjustment of such scales by utilizing a materials weight test, the procedures for which the Parties shall mutually agree. The Parties shall split all costs of any such materials weight test unless the scale is found to be in error in excess of the manufacturer’s accuracy tolerances. If the scale is found to be in error, the Party owning/maintaining the scale shall pay all costs of the test. If a test reveals error in weight in excess of the manufacturer’s specified tolerances, the scale shall be adjusted to an accurate condition, and an appropriate retroactive adjustment shall be made in the invoices and payments affected by such inaccuracy; provided, however, no such adjustment shall be made for a period in excess of the lesser of (i) one half (1/2) of the period since the date that either Party first questioned the accuracy of the weights and the date of the last regularly scheduled test of the scales, or (ii) three Months.

General

If either Party is rendered unable, wholly or in part, by Force Majeure (as hereinafter defined) to carry out any of its obligations under this Agreement, and if within five (5) Business Days after the Party experiencing a Force Majeure is aware of the occurrence of such Force Majeure provides notice, including a detailed explanation of such Force Majeure, to the other Party, then the obligations of the Party giving such notice shall be suspended to the extent made necessary by such Force Majeure from the inception of the Force Majeure and during its continuance, but for no longer. The Party giving such notice shall diligently use its best efforts to eliminate the cause and effect of such Force Majeure insofar as possible with all reasonable dispatch. Any deficiencies in the production or delivery of lignite hereunder caused by Force Majeure shall not be made up under the provisions of this Agreement except by mutual agreement. No such event of Force Majeure shall excuse, alter or diminish the obligation of Buyer to make the payments provided for in Section 7 in accordance with Section 8. Notwithstanding anything to the contrary herein, this Agreement may, subject to Section 16.3, be terminated by Buyer if a Force Majeure affecting Seller and its effect are not eliminated within thirty (30) months from inception of such Force Majeure.

13.2

Definition

The term “Force Majeure” as used in this Agreement shall mean any and all causes beyond the reasonable control of the Party failing to perform, such as acts of God, strikes or other industrial disturbances, material shortages, labor organizing efforts, acts of the public enemy, wars, blockades, insurrections, riots, acts of terrorism, epidemics, pandemics, landslides, adverse geological or hydrological conditions, faults in lignite seams, lightning, hurricanes, tornadoes, earthquakes, fires, storms, floods, washouts, major breakdowns of or damage to Plant or Mine facilities (including haul roads between the Mine and the Plant), Plant or Mine equipment, interruptions to or contingencies of transportation, orders or acts or refusals to act by a governmental, military or civil authority (including without limitation, interruptions, whether by action or inaction, by federal, state or local governments or court orders, present and future, or acts or failures to act of any Governmental Entity having proper jurisdiction) and any other causes, whether of the kind herein enumerated or otherwise, beyond the reasonable control of the Party failing to perform, that wholly or partly prevent the mining, producing, processing and delivering of the lignite by Seller or the receiving and/or utilizing of the lignite by Buyer. The settlement of strikes or industrial disputes or disturbances or the resolution of labor organizing efforts shall be entirely within the discretion of the Party whose employees are affected, and the above requirement that any Force Majeure shall be remedied with all reasonable dispatch shall not require the settlement of strikes or the resolution of labor organizing efforts by acceding to the demands of the opposing party therein when such course is inadvisable in the discretion of the Party having the difficulty. A decrease in or lack of demand for electricity from Plant shall not constitute Force Majeure.

-33-

15.9

Exclusive Remedies; Limitation on Damages

The remedies provided for in this Agreement are the exclusive remedies of the Parties for violation of the terms and conditions of this Agreement and the NACoal Guaranty, as permitted by Applicable Law. Each Party acknowledges that it is sophisticated, has been represented by counsel, does not have disproportionate bargaining power in respect of remedies and voluntarily agrees to the limitations on remedies herein. No Party shall seek, and each Party hereby waives the right to seek, and agrees to prevent its Affiliates from seeking, any other remedies, whether available at law, in equity or otherwise; provided, however, that Seller and Buyer shall each have the right to seek temporary or permanent injunctions in the event that a breach of this Agreement has occurred and the affected Party reasonably concludes that such breach cannot be adequately addressed by money damages. Each Party hereby agrees that only the actual damages suffered by a Party shall be sought and may be recovered. None of the following types of damages shall be sought or recovered: consequential damages, indirect damages, exemplary damages, punitive damages, replacement fuel costs (except as provided in Section 2.9(b)(iii) and Section 2.9(c)), replacement power costs, and all similar types of damages and remedies. In the event Buyer breaches Section 2.3 by utilizing any fuel for the Plant other than Seller’s lignite, Buyer agrees that Seller shall be entitled to recover (a) its Agreed Profit over the remaining portion of the Term, excluding automatic extensions (assuming that Seller would have sold to Buyer 2,500,000 Tons annually), (b) the Cost of Production incurred by Seller before and after such breach, and (c) any amounts owed by Buyer in accordance with Section 7.3 and Section 15.8(b), as a measure of Seller’s actual damages and as an exclusive remedy for such breach. The remedy set forth in the preceding sentence shall not apply in the event this Agreement terminates in accordance with Section 16.1 or Section 16.2.

Section 16.

Certain Early Termination Events; Purchase of Seller’s Membership Interests Upon Termination

16.1

Automatic Early Termination for Governmental Order or Applicable Law Directly Prohibiting Mining or Use of Lignite

In the event that any final, non-appealable Governmental Order or Applicable Law, of indefinite duration (excluding any Governmental Order that results in fees, penalties or assessments as referred to in Section 7.2(a)(i)(kk)), is adopted after the Effective Date that either: (a) directly prohibits the mining, processing, loading or delivery of lignite as contemplated under this Agreement or (b) directly prohibits the receiving, accepting, unloading or use of lignite at the Plant as contemplated by this Agreement, then, when such prohibition is final and non-appealable or the Applicable Law becomes effective, Buyer shall be required to purchase Seller’s Membership Interests in accordance with Section 16.3, and this Agreement shall terminate.

16.2

Early Termination by Buyer for Certain Governmental Order or Applicable Law

In the event that Buyer closes the Plant or switches the fuel used by the Plant to a fuel other than lignite for a continuous period of more than twenty-four (24) months in response to Governmental Orders or Applicable Laws that cause Buyer to conclude that further operation of the Plant or use of lignite as fuel for the Plant is economically unfeasible, Buyer shall have the right to terminate this Agreement effective on the date of such closure of the Plant or the first day of the Plant outage that accommodates the Plant’s fuel switch, at which time Buyer shall be required to purchase Seller’s Membership Interests in accordance with Section 16.3.

16.3

Early Termination Buyout

16.3.1 In the event of a termination of this Agreement prior to the expiration of the Term or a termination of the Production Period prior to December 31, 2040, Buyer shall, or shall cause its affiliate to, promptly purchase Seller’s Membership Interests pursuant to the terms and conditions of a purchase and sale agreement for an amount equal to the Equity Value (the “Early Termination Buyout”).

-39-

16.3.2 In the event that a termination of this Agreement referred to in Section 16.3.1 occurs on or after January 1, 2024, Buyer’s obligations under Section 16.3.1 shall be conditioned on NACoal simultaneously purchasing from Seller:

(a)

all of Seller’s right, title and interest in its electric walking dragline(s) (the “Dragline”) pursuant to the terms and conditions of a purchase and sale agreement for an amount equal to the then Net Book Value of the Dragline; and

If Seller’s right, title and interest in the Rolling Stock is as lessee under a lease, the condition provided for in this Section 16.3.2(b) shall be satisfied if NACoal shall take an assignment of all of Seller’s rights under such lease and NACoal shall assume and be responsible for all of Seller’s obligations under such lease.

16.4

Mine Reclamation Obligations After Early Termination Buyout

In the event of an Early Termination Buyout, (a) Buyer shall own Seller and control the Reclamation Account, and shall cause Seller to complete mine closure and post-mining reclamation as required by Applicable Laws through final release of the Mine reclamation bond by the North Dakota Public Service Commission; (b) Buyer shall fund the cost thereof using funds from the Reclamation Account or provided by Buyer; (c) NACoal and its Affiliates shall have no obligation or liability related to final Mine closure and reclamation; and (d) Buyer shall indemnify and hold harmless NACoal and its Affiliates from and against any such obligation or liability.

In the event of any Early Termination Buyout (other than due to an event of Seller Default) or upon the buyout at the conclusion of the Term, the NACoal Guaranty shall terminate, except in respect of any Seller obligations under Section 15, and NACoal shall have no other obligations on account of the NACoal Guaranty.

-40-

Section 17.

Effect of Waiver

Waiver by either Party of any breach by the other of any of the terms and provisions hereof or failure to exercise any option or right hereunder shall not be deemed to be a waiver of such breach, option or right on any other occasion of the same, nor a waiver of breach of any other term or condition nor a waiver of any other right to exercise any option or right.

Section 18.

Arbitration

18.1

Disputes Subject to Arbitration

Except as otherwise provided in this Agreement, any dispute between the Parties arising out of this Agreement for which the ultimate resolution is not expressly provided by this Agreement or for which arbitration is not expressly excluded shall be resolved by arbitration.

18.2

Notice of Arbitration

18.2.1 The Parties shall first make a diligent good faith attempt to resolve the dispute by mutual agreement. If a dispute has not been resolved within thirty (30) Days of being raised, the manager of the Mine and the manager of the Plant shall meet at least three times over a period of thirty (30) Days and shall attempt in good faith to resolve such dispute. If the dispute is not resolved by the managers, the chief executive officers of NACoal and Otter Tail (or the then-acting agent of the Utilities under the Plant Ownership Agreement if Otter Tail is not then so acting) shall meet at least two times over the immediately following period of thirty (30) Days and shall attempt in good faith to resolve such dispute. If the dispute is not resolved in either meeting, either Party may request arbitration by notice delivered to the other Party in writing within thirty (30) Days of the conclusion of the meetings of the chief executive officers. Such notice shall set forth in detail all claims to be arbitrated, and the amount(s) involved, if any. Such arbitration notice shall specify the position of the Party giving the notice in respect of each claim, the reasons therefor and the remedy sought in respect of each claim. Such arbitration notice shall be delivered to the other Party within one hundred twenty (120) Days of the date of the first knowledge of the claiming Party of the occurrence or conditions giving rise to the dispute. Any failure to request arbitration within such one hundred twenty (120) Day period shall be deemed a waiver of the right to arbitrate or litigate the dispute.

18.2.2 Within thirty (30) Days after an arbitration notice is received, the receiving Party shall by notice to the other Party specify its position in respect of each claim, the reasons therefor and the remedy sought in respect of each claim. All persons eligible to act as an arbitrator shall be disinterested persons qualified by experience to hear and determine the questions to be arbitrated, and if the nature of any such question shall so require, they shall be geologists or mining engineers experienced in the exploration for or mining of minerals under operating conditions similar to those which may be encountered in the South ▇▇▇▇▇▇ Area of Interest.

18.3

Selection of Arbitrators and Arbitration Proceedings

The dispute shall be arbitrated by a panel of three arbitrators meeting the criteria in Section 18.2.2, selected pursuant to the Commercial Arbitration Rules of the American Arbitration Association (“AAA Rules”). The arbitrators and Buyer and Seller shall complete hearings in Bismarck, North Dakota on the matters to be arbitrated within sixty (60) Days after the appointment of the arbitrators. The arbitrators shall make such examinations and investigations as they may deem necessary and shall render their decision in writing within thirty (30) Days following such hearings. The sixty-day hearing period and the thirty-day decision period may not be extended by the arbitrators for any reason without the prior written consent of Seller and Buyer, which may be withheld by either of them in their sole and absolute discretion.

-41-

18.4

Decision of the Arbitrators

The decision of the arbitrators shall be final and binding on the Parties, and judgment thereon may be entered in any court of competent jurisdiction. Except as herein otherwise specified, the arbitration shall be conducted pursuant to the AAA Rules in effect at the time of such arbitration and the cost and expense for the arbitration shall be shared equally between the Parties.

18.5

Certain Matters Not Subject to Arbitration

Seller may not initiate arbitration challenging a Buyer determination, approval or disapproval that Buyer is entitled to make under the terms of this Agreement, including without limitation under Section 2.6 (Designation of Deliveries), Section 5.2 (Mining Plans), Section 6.2 (Buyer’s Right to Replace Loans and Leases), Section 10 (Insurance) and Section 12.3 (Periodic Inspections), unless (a) Seller believes that any such Buyer determination, approval or disapproval is reasonably likely to be construed or interpreted in a fashion that would require Seller, in Seller’s reasonable opinion, to violate any Applicable Laws or create the risk of injury to any person or physical or environmental damage to any property and (b) Buyer does not agree with Seller’s opinion, in which case such a disagreement will be resolved by arbitration pursuant to this Section 18. During the pendency of such an arbitration, Seller will not be required to implement the disputed determination, approval or disapproval of Buyer.

18.6

No Excuse of Performance

The existence of a dispute that has or may become the subject of an arbitration shall in no way excuse either Buyer or Seller from performing its obligations under this Agreement, and each of the Parties shall continue to perform in accordance with the terms of this Agreement irrespective of the existence of any such dispute.

20.1

Proprietary and Confidential Data

(a)

Except as otherwise required under Applicable Laws, Buyer and Seller shall maintain as strictly confidential and not disclose to any third party nor use or exploit for any purpose other than the purpose of this Agreement, Confidential Information provided to the other Party, that is owned by the disclosing Party, licensed by the disclosing Party from a third party, or disclosed by the disclosing Party under this Agreement.

Each Party agrees to permit access to the Confidential Information of the other Party only by those employees, consultants, attorneys of the Parties and their Affiliates and their independent contractors who have a need to know and who have been informed that the Confidential Information is subject to confidentiality and non-use obligations under this Agreement and have confidentiality and non-use obligations with respect to the Confidential Information that are at least equivalent to those contained under this Agreement.

Section 22.

Miscellaneous

22.1

Action by Buyer

In any instance when Buyer shall be unable to take action on any matter arising under this Agreement due to a lack of unanimous agreement among the Utilities, the concurrence of the Utilities holding the required percentage of the ownership shares in the Plant under the then-current Plant Ownership Agreement (or its equivalent if none is then in effect) shall be deemed to be the action of all the Utilities and shall be binding upon Buyer provided that such action shall have been taken at a meeting properly noticed in accordance with the Plant Ownership Agreement. In the event that such concurrence cannot be obtained and such failure does not effectively prohibit Seller from so performing, Seller shall continue to perform in accordance with the Annual Mining Plan then in effect.

22.2

Agent for Buyer

The Utilities shall, in enforcing any right, giving any notice or taking any action under this Agreement, act jointly through Otter Tail who shall be deemed the agent for all of the Utilities for purposes of this Agreement. In addition, Seller may deal with Otter Tail as the representative of Buyer for any purpose in connection with this Agreement, and any notice given to Otter Tail in accordance with Section 22.12 shall be deemed to have been given to each Utility. Buyer may, at any time, replace Otter Tail as the agent for purposes of this Agreement with any one of the other Utilities in accordance with the provisions of the Plant Ownership Agreement, and by jointly giving Seller notice of such replacement in accordance with Section 22.12 of this Agreement.

22.5

Severability

The invalidity or unenforceability of any particular provision of this Agreement shall not affect the other provisions hereof unless it substantially and adversely affects the value of this Agreement to one of the Parties; and in the absence of any such substantial and adverse effect, this Agreement shall be construed in all respects as if such invalid or unenforceable provision were omitted.

-46-

22.6

1. Guaranty by The North American Coal Corporation. FOR VALUE RECEIVED, the sufficiency of which is hereby acknowledged, THE NORTH AMERICAN COAL CORPORATION, a Delaware corporation (“Guarantor”), does hereby unconditionally and absolutely guarantee, as a primary obligor and not merely as a surety, to OTTER TAIL POWER COMPANY, a Minnesota corporation (“Otter Tail”), NORTHERN MUNICIPAL POWER AGENCY, a political subdivision and municipal corporation of the State of Minnesota (“Northern Municipal”), MONTANA-DAKOTA UTILITIES CO., a division of MDU Resources Group, Inc., a Delaware corporation (“Montana-Dakota”) and NORTHWESTERN CORPORATION, a Delaware corporation doing business as NorthWestern Energy (“Northwestern” and, together with Otter Tail, Northern Municipal and Montana-Dakota, the “Owners”), and each of their successors and assigns (the Owners and their successors and assigns collectively referred to as “Principals”), the full and prompt payment and performance by COYOTE CREEK MINING COMPANY, L.L.C., a Nevada limited liability company (“Seller”), of each and every covenant, agreement and obligation of Seller (the ”Obligations”) set forth in the Lignite Sales Agreement, dated as of October 10, 2012 (the “LSA”), by and between Seller and the Owners. This is a present and continuing guaranty of payment and performance of the Obligations and not of collection.

2. Amendment of the LSA. Guarantor acknowledges and agrees that the LSA may be amended and modified from time to time and that the performance of Seller thereunder may be modified or waived from time to time and that no such amendment, modification or waiver shall serve to limit, reduce or waive Guarantor’s obligation hereunder as a primary obligor under the LSA as so amended or modified, whether or not Guarantor has received notice of such amendment, modification or waiver.

3. Certain Waivers. Guarantor waives presentment, demand, notice of dishonor, protest, notice of protest, nonpayment or default to Seller or Guarantor, and all other notices to which Guarantor may otherwise be entitled, other than notices to which Seller is entitled pursuant to the LSA. Guarantor hereby waives all surety defenses, except indefeasible payment and performance in full.

4. Direct Guaranty; Partial Performance. The liability of Guarantor under this Guaranty shall be direct and immediate and not conditional or contingent upon the pursuit of any remedies against Seller or any other person or entity. Guarantor irrevocably waives any and all rights to require that an action be brought against Seller or any other person or entity prior to action against Guarantor hereunder. If the Obligations are partially performed through the election of Principals to pursue any of the remedies mentioned herein or if any Obligation is otherwise partially performed, Guarantor shall remain unconditionally and absolutely liable for the entire cost of Principals’ partial performance of the Obligations and the entire unperformed amount of any such Obligations.

5. Bankruptcy. The obligations of Guarantor under this Guaranty shall remain in full force and effect without regard to, and shall not be released, discharged or in any way modified or otherwise affected by any bankruptcy, insolvency, reorganization, arrangement, readjustment composition, dissolution, liquidation or similar proceeding with respect to Seller or the properties or the creditors of Seller or any action taken by any trustee or receiver or by any court in any such proceeding. Guarantor agrees to pay Principals’ reasonable attorneys’ fees incurred in successfully enforcing their respective rights under this Guaranty. Guarantor agrees that, if at any time all or any part of the payments theretofore applied by Principals from Seller to any Obligation is rescinded or Principals are required to pay any amount thereof to any party due to the insolvency, bankruptcy, liquidation or reorganization of Seller or the determination that such payment by Seller is held to constitute a preference under the bankruptcy laws, such Obligation and/or Guarantor’s liability hereunder shall, for the purposes of this Guaranty, be deemed to have been continued in existence to the extent of such payment, and this Guaranty shall continue to be effective or reinstated, as the case may be, as though such application by Principals had not been made and Guarantor agrees to pay such amount to Principals upon demand. Notwithstanding anything to the contrary in this Guaranty, Principals shall not have any rights under this Guaranty, and this Guaranty shall be void and of no force and effect, with respect to a Bankruptcy or the insolvency of Seller that directly results from a Principal’s breach of any of its payment or other obligations under the Agreement.

6. Severability. In the event that any one or more provisions contained herein shall for any reason be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision hereof and this Guaranty shall be construed as if such invalid, illegal or unenforceable provision had never been contained herein.

7. Duration; Setoff; Successors. Except for any settlement or compromise of the Obligations voluntarily entered into by Principals, or any of them, this is a continuing Guaranty until all Obligations have been extinguished, and Guarantor agrees, subject to the foregoing exception, that the obligations, covenants and agreements of Guarantor hereunder shall not be discharged, affected or impaired by any act, event or condition other than full performance and indefeasible payment in full of the Obligations; provided, however, that this Guaranty shall terminate and Guarantor shall be relieved of its obligations under the terms of this Guaranty to the extent provided in Section 16.6 of the LSA. Guarantor expressly waives any rights to setoff or subrogation. The provisions of this Guaranty shall be binding upon Guarantor and its successors and assigns, and shall inure to the benefit of Principals and their respective successors and assigns.

8. Representations and Warranties. Guarantor represents and warrants to Principals as follows:

EXHIBIT C

Example of Adjustment of the Adjustable Amounts

The formula for adjustment of the Adjustable Amounts is as follows:


AA =	x	times the Adjustable Amount
AA =	y	times the Adjustable Amount

Where:

AA = the Adjustable Amount

x = Value of CPI-U Index for the third Month immediately preceding the January 1, April 1, July 1 or October 1 adjustment date under consideration

y = Value of CPI-U Index for June 2011 (which is 225.722, on the base 1982-1984 = 100)

Example calculation of Agreed Profit to be made on [January] 1, 20[12]:

Note:

The CPI-U Index figures used in this Exhibit C are examples only and are not intended to relate to actual circumstances or to be used in actual calculations.

x = [October] 2011 CPI-U Index = [227.000]

y = June 2011 CPI-U Index = 225.722


	[227.000]
AA =	225.722	X [] = [] X [**]

AA =	[**]	(which amount would be used as the billing basis for the Agreed Profit for the period from [January] 1, 20[12] to [April] 1, 20[12], with such adjustment to be included in the first invoice following [January] 1, 20[12]).

If the CPI-U Index for [October] 2011 were later revised, there would be no further adjustment of the Adjustable Amounts on the basis of such revision.
