ARTICLE III—SALE AND PURCHASE OF LANDFILL GAS

3.1                               Sale and Purchase: Quantity—Except as provided in Section 3.2 below: Seller shall make available to Buyer for purchase all of the LFG that Seller extracts from the Landfill. It is the mutual expectation of Seller and Buyer that the Landfill will generate, and Seller will make available to Buyer, those quantities of Landfill Gas as described in Exhibit B attached hereto and incorporated herein. Seller agrees to deliver and sell to Buyer and Buyer agrees to accept and purchase from Seller all of its LFG up to those quantities shown in Exhibit B, available for use by Buyer in Buyer’s Facility, starting on the date that LFG is first delivered by Seller to the Delivery Point. Buyer will not be obligated to pay Seller for any LFG requirements until the date that Seller begins providing delivery of LFG to the Delivery Point. Any LFG produced by the Seller in excess of the quantities shown in Exhibit B will be made available for purchase by Buyer, but Buyer shall not be required to purchase such gas. Buyer shall notify Seller for the subsequent quarter in writing no later than the first day of the preceding quarter during the term of this Agreement whether it intends to accept LFG in excess of the amounts shown in Exhibit B and the amount it would accept if available for the succeeding quarter (for purposes of clarity, Buyer shall give notice by January 1 for each quarter beginning April 1 of that calendar year, by April 1 for the quarter starting July 1 of that calendar year, by July 1 for each quarter starting October 1 of that calendar year, and by October 1 for each quarter starting January 1 of the following calendar year). Notwithstanding the twelve (12)-month moratorium identified in Section 5.1, should Buyer fail to accept excess LFG for three consecutive quarters, Seller shall no longer be required to make such excess production available to Buyer as provided for herein. Once notice is given as set forth above, the election shall be binding upon both Buyer and Seller.

3.2                               Price. The price of LFG for the amounts identified in Exhibit B and purchased by Buyer during the term of this Agreement shall be $4.00 per MMBTU plus applicable taxes and fees. For any amounts of LFG provided in excess of the amounts identified in Exhibit B, Buyer shall pay Seller $2.50 per MMBTU plus applicable taxes and fees. If the Buyer extends the term of this Agreement as provided for in Article 4.1 of this Agreement, the price per MMBTU of all LFG sold under this Agreement during the extended period after the initial ten (10)-year term of the Agreement, will vary monthly based on the market price of natural gas. The price for LFG in each month during the extended period after the initial ten (10)-year term of the Agreement will be equal to 50 percent of the closing NYMEX® Henry Hub Natural Gas price as of the close of trading on the last trading day prior to each month. All LFG sold under this Agreement is subject to price adjustments as provided for in Article 5.1 of this Agreement.

3.3                               Invoices, Payment. Seller shall electronically record the total monthly LFG flow for the monthly period between the 26th day and the 25th day of each monthly period from the Facility Flow Meter. Seller shall calculate MMBTU Content based on the average methane content recorded electronically by the Landfill Methane Meter over the monthly invoicing period. Seller shall prepare and send to Buyer by the 15th day of each month an invoice which shall be accompanied by a report showing amounts for monthly LFG volume, average methane content, and

4

calculated monthly MMBTUs. Buyer shall remit payment to Seller within thirty (30) days following receipt of Seller’s invoices, which payment date shall be identified on Seller’s invoices.

3.4                               Meter Tests. Seller shall maintain the meters used to measure the LFG in good condition and repair, and shall have their respective meter inspected periodically by a reputable third party, but at least once each year. Copies of the inspection reports shall be made available to the other party upon request.

3.5                               Meter Out-of-Service. If, for any reason, the Facility Flow Meter is out-of-service or out-of-repair so that the amount of LFG delivered and used by Buyer cannot be ascertained or determined from its readings, the volume content of LFG delivered to Buyer during such period when the Facility Flow Meter is out-of-service shall be determined by utilizing readings from the Landfill Flow Meter installed by Seller at the Landfill taking into account any recurring changes in volume between the Landfill Flow Meter and the Facility Flow Meter.

3.6                               Errors in Billing. Should either party find at any time within one (1) year after the date of any invoice rendered by Seller that there has been an undercharge or an overcharge in the amount billed in the invoice, the party finding the error shall promptly notify the other party in writing. In the case of an undercharge, Seller shall submit a statement for such undercharge, and Buyer, upon verifying the same, shall pay such an amount within thirty (30) days after receipt of the statement but without interest. In the case of an overcharge, Seller shall refund the amount of the overcharge to Buyer within thirty (30) days of notification by Buyer, but without interest. Neither Seller nor Buyer shall have any liability for any undercharge or overcharge relating to invoices over one year old.
