1.       TERM, SCHEDULING, QUANTITY, PRICE, & BALANCING

1.1     This Agreement shall commence as of the first date written above and remain in effect, subject to the termination rights set forth herein, until terminated by either Party in a manner not inconsistent with an effective Confirmation. Except with respect to termination resulting from an Event of Default, if one or more Confirmations is in effect, termination of the Agreement shall not be effective until the expiration of the latest Delivery Period as provided in an effective Confirmation.

1.2     Seller agrees to sell and schedule for delivery to Buyer, and Buyer agrees to purchase and receive from Seller, natural gas as set forth in any Confirmation effective between the Parties, as it may be amended from time to time with mutual agreement of the Parties.

1.3     The Price for the Baseload or Contract Quantity, as applicable, shall be set forth on the applicable Confirmation. In the event that the Price is identified as “NYMEX Last Day Settle plus Market Basis” (or “NYM LDS plus Mkt Basis”), then the Price shall be the sum of two price components: (i) Commodity, and (ii) Basis. The Commodity price shall be equal to “NYMEX Last Day Settle”, as defined in the Definitions Rider, for the applicable month, unless the Parties mutually agree to fix the Commodity price. The Basis price shall be reasonably determined by Seller unless the Parties mutually agree to a Basis price.

1.4     A mutual agreement, if any, to establish a fixed Price, (whether the Commodity, Basis or both price components) may take the form of counterparts, with the Buyer submitting an offer and the Seller indicating its agreement to the terms of such offer in separate writings. Buyer and Seller agree that any written fixed price request(s) submitted by Buyer shall be deemed an offer by Buyer to buy. Only terms (i) affirmatively confirmed by Seller in a Confirmation amendment in response to Buyer’s fixed price request, or (ii) contained in a fully executed Confirmation, shall be binding on the Parties. Neither Buyer nor Seller shall contest the enforceability of an agreement on the grounds that the agreement is in counterparts as described herein, the fixed price request or Confirmation amendment is delivered in an electronic form or by facsimile, or that either of a fixed price request or a Confirmation amendment as described herein is not a writing. Quantities with fixed prices (or a fixed price component) shall be deemed the first natural gas through the meter with respect to the applicable month.

1.5     In the event that the quantity of natural gas that can be delivered to Buyer is less than the quantity agreed to be purchased for the relevant period, Buyer shall remain liable for the entire quantity it agreed to purchase. Seller will provide a credit at prevailing market prices for that portion of the purchased quantity that could not be delivered. In the event that Buyer’s expected Use will exceed the quantity of gas purchased by Buyer and/or available to Buyer without incurring Imbalance Charges for the relevant period, Seller will use commercially reasonable efforts to provide Incremental Supply at prevailing market prices as adjusted for Fuel, if applicable, and margin. Credits for Cashout and/or charges for Incremental Supply shall appear as separate line items on Seller’s invoice to Buyer, including applicable price and quantity. If no Balancing Service is

noted on the effective Confirmation, then notwithstanding the terms of Sections 1.5, 1.6 and 1.7 herein, Buyer is responsible for all balancing activities, and Buyer shall pay all Imbalance Charges and charges related to Cashout. In the event that Seller delivers and Buyer accepts gas to Accounts after the expiration of the applicable Confirmation, the Price for such post-expiration sales shall be NYM LDS plus Mkt Basis.

1.6     Buyer and Seller shall use commercially reasonable efforts to provide each other with sufficient notice to allow timely and accurate nominations in accordance with the nomination requirements of that Transporter, as they may change from time to time due to Constraint Day requirements or otherwise. Buyer accepts the following responsibilities: Buyer hereby appoints Seller as its agent for the purposes of balancing, including the receipt of current and historic Usage, storage, billing and transportation data from Transporter. Buyer agrees to assist Seller in the timely collection of data directly and through Transporter, notify Seller of usage expectations and any material changes to those usage expectations, and comply with any Daily Limitations concerning use. If Usage data is unavailable electronically, Buyer shall obtain usage data manually and deliver that information weekly via facsimile or electronic mail, or as requested by Seller.

1.7      If Balancing Service is indicated on the applicable Confirmation, Seller agrees to monitor and review all information provided to the Seller by Buyer and Transporter regarding Buyer’s gas Use. Based on such information, Seller shall use commercially reasonable effort to keep Buyer within the balancing parameters established by Transporter. Seller shall pass through to Buyer and Buyer shall pay for any Imbalance Charges and/or Cashout resulting from Buyer’s failure to (i) fulfill its obligations set forth in 1.6, (ii) maintain telemetry if applicable, and/or (iii) meet Daily Limitations with respect to Use.

Gas Inventory. Unless Buyer’s Accounts are billed on nominations (rather than actual use), when Buyer’s Accounts are enrolled, Seller shall acquire any inventory of gas allocated to Buyer’s Accounts by Transporter, if any, and credit Buyer for that inventory at prevailing market prices. Upon termination of the Agreement, or as otherwise agreed upon by the Parties in a Confirmation, Seller shall have the right, to credit Buyer’s Account with gas and charge Buyer prevailing market prices as adjusted for Fuel for such gas.

2.       BILLING AND PAYMENT

2.1     Seller shall submit to Buyer an invoice setting forth the quantity of natural gas purchased by Buyer during the preceding month and the total amount due. Billing will be based on actual Use plus applicable Fuel, unless otherwise provided on the applicable effective Confirmation. If the actual Use is not available from the Transporter by the invoice date, the invoice may be based on an estimate using nominated quantities, or as otherwise provided in the applicable effective Confirmation. Buyer shall remit payment to Seller within ten days of the invoice date for the total amount due set forth on the invoice. Payments that exceed $50,000 shall be made by wire transfer, EFT or ACH.

Payments shall be made by wire and/or ACH to:

US Bank ABA - 075000022

Acct - 182380410411

Payment by Check shall be made payable to:

Integrys Energy Services - Natural Gas, LLC

P.O. Box 3145

Milwaukee, WI 53201-3145

If Consolidated Billing is indicated on the effective Confirmation, then Seller shall include the Transporter distribution fees on the monthly invoice. Past due and other charges due Transporter, that apply to service prior to the effective date of the Confirmation will not be included in Seller’s invoice to Buyer. Seller may discontinue this service at any time with notice to Buyer.

2.2     If Buyer disputes the amount payable under any invoice rendered hereunder, Buyer shall pay when due the amount not in dispute under such invoice as well as provide documentation to support the amount paid or disputed. Buyer recognizes that Buyer’s assertion of an inaccurate Usage determination by Transporter, in the absence of a redundant metering device to support that claim, is not adequate support to withhold payment. Any payment by Buyer shall not be deemed to be a waiver of Buyer’s right to recoup any overpayment, nor shall acceptance of any payment be deemed to be a waiver of Seller’s right to any underpayment. Any claim must be made within two (2) years of the date of the invoice or last revision thereof.

2.3     In the event the Buyer falls to pay the undisputed amount due to Seller when due, the unpaid portion of the undisputed amount shall accrue at a rate equal to one and one half percent (1-1/2%) per month, provided that in no event shall such rate exceed the maximum rate allowed by law, compounded daily from the date such payment is due until the same is paid.

3.       FINANCIAL RESPONSIBILITY

Buyer (i) agrees to provide Seller with required information, including pertinent financial information and other information required for Seller to assess Buyer’s financial position, and (ii) authorizes the applicable utility, credit reporting agencies, trade references, and other relevant parties to release data to Seller relating to Buyer’s billing, usage, and credit data with such authorization enduring for the term of this Agreement. When reasonable grounds for insecurity of payment arise, including without limitation when Buyer seeks to establish a fixed price (whether Commodity, Basis or both), Seller may demand adequate assurance of performance. Adequate assurance of performance must be delivered to Seller no later than three (3) Business Days after the date of request, and must be in a form, from an issuer, and in an amount, acceptable to Seiler.

4.       EVENT OF DEFAULT

Upon the occurrence of an Event of Default, the Party not committing the Event of Default (“Non-Defaulting Party”) shall have the right to suspend service and/or terminate this Agreement, including all effective Confirmations, in addition to any and all other remedies available hereunder.

5.       REMEDY

5.1     During any Delivery Period, if either Party commits an Event of Default (the “Defaulting Party”), then the Defaulting Party shall pay and the Non-Defaulting Party shall be entitled to, as its exclusive remedy, early termination damages arising out of the Event of Default as reasonably calculated by Seller (“Early Termination Damages”). The Parties expressly acknowledge that should an Event of Default occur, damages would be difficult to ascertain and quantify, and agree that this provision for calculating damages (i) is reasonable in light of the anticipated or actual harm, (ii) shall be followed in lieu of any other methods of calculating or estimating direct actual damages, and (iii) is not a penalty.

5.2     If Seller commits an Event of Default and the price for replacement natural gas, including any associated costs reasonably incurred by Buyer in obtaining replacement natural gas, is higher than the Price set forth on the applicable Confirmation (as it may be amended), then Seller shall pay Buyer Early Termination Damages in the amount of such positive difference multiplied by the Contract Quantity or Baseload Quantity, as applicable.

5.3     If Buyer commits an Event of Default and the price at which Seller re-sells or could re-sell natural gas, less any associated costs reasonably incurred by Seller, is less than the amount that would have been paid under the applicable Confirmation, then Buyer shall pay Seller Early Termination Damages in the amount of such positive difference multiplied by the Contract Quantity or Baseload Quantity, as applicable. In determining the price at which Seller could re-sell the natural gas, Seller may consider quotations for replacement transactions supplied by one or more third parties and relevant market data supplied by one or more third parties or internal sources, provided that information from internal sources must be of the same type used by Seller in the regular course of its business for the valuation of similar transactions. Seller shall act in good faith and use commercially reasonable procedures when determining the price at which natural gas could have been resold.

5.4      In the event that the Contract Quantity or Baseload Quantity is identified as Full Requirements on the applicable Confirmation, then the Parties agree that Seller’s forecasted quantity for Buyer for the applicable period should be used when calculating the remedy due the Non-Defaulting Party. Payment for Early Termination Damages shall be due within two (2) Business Days of the invoice date for said Early Termination Damages. In the event the Defaulting Party fails to pay amounts in accordance with the previous sentence, the Defaulting Party shall be responsible for (i) interest equal to one and one half percent (1 1/2%) per month, provided that such rate does not exceed the maximum rate allowed by law, compounded daily from the date such payment is due until the same is paid and (ii) all reasonable costs of collection, including attorneys’ fees.
