DEDICATION AND QUANTITY 1.1 Subject to the other provisions of this Agreement, Seller does hereby commit and dedicate to the performance of this Agreement and agrees to sell and deliver to Buyer hereunder one hundred percent (100%) of the Gas production which Seller owns, controls or has the right to sell, pursuant to the Conveyance (as such Exhibit may from time to time be amended, restated, supplemented, or otherwise modified) and that is capable of being transported to Buyer's Purchaser under contracts with Buyer's Transporters (herein called the "Marketed Volumes"). Seller represents and warrants that it has the right to market and sell to Buyer hereunder the Marketed Volumes. Seller hereby agrees to sell to Buyer, and Buyer hereby agrees to purchase from Seller, upon the terms of this Agreement all of the Marketed Volumes which are actually delivered to and accepted by Buyer's Purchaser. 1.2 During the term hereof and as required by the applicable Buyer's Marketing Agreements, Seller shall provide to Buyer, or to Buyer's designee, a written nomination setting forth the quantity of Gas to be delivered to Buyer, or to Buyer's designee, each Day during such Month (herein called the "First-of-the-Month Nominated Quantity"). Seller shall provide to Buyer, or to Buyer's designee, such notice as is required by the applicable Buyer's Marketing Agreements prior to 2 5 any Day for which Seller desires to nominate a quantity of Gas for sale and delivery hereunder that is different from the First-of-the-Month Nominated Quantity. 1.3 In no event shall the volumes of Gas that Seller is obligated to sell and deliver to Buyer, or to Buyer's designee, or that Buyer or Buyer's designee have agreed to purchase and receive from Seller under the terms of this Agreement ever exceed the volumes of Gas which can be legally produced or purchased under the applicable rules and regulations of the Railroad Commission of Texas. 1.4 In consideration of the execution and delivery of this Agreement by the Buyer, the Seller hereby indemnifies, exonerates and holds the Buyer and each of its respective officers, directors, employees and agents (herein, collectively, called the "Indemnified Parties") free and harmless from and against any and all actions, causes of action, suits, losses, costs, liabilities, damages and expenses (including, without limitation, reasonable attorney's fees and disbursements) incurred in connection therewith (irrespective of whether any such Indemnified Party is a Party to the action for which indemnification hereunder is sought), excluding any portion of such actions, causes of action, suits, losses, costs, liabilities, damages and expenses (including, without limitation attorney's fees and disbursements) resulting from the gross negligence or wilful misconduct of any Indemnified Party (herein collectively called the "Indemnified Amounts"), incurred by the Indemnified Parties or any of them as a result of, or arising out of, or relating to (1) Buyer's Marketing Agreements or (2) this Agreement. IT IS UNDERSTOOD BY THE PARTIES HERETO THAT THE INDEMNITIES BY SELLER IN FAVOR OF THE BUYER IN THIS AGREEMENT SHALL BE APPLICABLE NOTWITHSTANDING THAT ANY INDEMNIFIED AMOUNTS OTHERWISE COVERED BY THIS AGREEMENT ARE ATTRIBUTABLE TO THE NEGLIGENCE (OTHER THAN GROSS NEGLIGENCE OR WILFUL MISCONDUCT) OF BUYER (WITHOUT REGARD TO WHETHER SUCH NEGLIGENCE IS SOLE, JOINT, CONCURRENT, ACTIVE OR PASSIVE), ANY PRE-EXISTING CONDITION OR DEFECT OR ANY FORM OF STRICT LIABILITY. 1.5 In the event that Buyer incurs, owes or is liable for any Indemnified Amount under Section 1.4 above, Seller shall pay such Indemnified Amount by wire transfer of immediately available funds to Buyer within five (5) days following Buyer's written demand therefor. In addition to, and not in limitation of the foregoing, Buyer is hereby authorized at any time and from time to time, without notice to Seller, to setoff and apply any and all sums held and any other sums at any time owing to or for the credit or the account of Seller against any and all sums owing to Buyer (including, without limitation, reasonable attorney's fees and disbursements and any Indemnified Amount), together with interest on such amounts at the Agreed Rate until paid in full, irrespective of whether or not Buyer will have made any demand under this Agreement. Buyer agrees promptly to notify Seller after any such setoff and application. The rights of the Buyer under this Section 1.5 are in addition to other rights and remedies (including, without limitation, other rights of setoff) which Buyer may have. The provisions of Sections 1.4 and 1.5 shall survive the termination of this Agreement. 3 6 ARTICLE II. PRICE OF GAS AND NATURAL GAS LIQUIDS 2.1 The Price per MMBtu of Gas on which the Net Price shall be determined shall be the Price per MMBtu paid, calculated each Month by the relevant Buyer's Purchaser for such Gas (excluding Products of Processing) delivered hereunder during each applicable calendar Month from each field listed in Exhibit B hereto. As described in Section VIII of Exhibit A, Buyer will pay the Net Price to Seller for all Marketed Volumes (including Products of Processing) delivered to Buyer and subsequently delivered to the relevant Buyer's Purchaser and accepted and paid for by such Buyer's Purchaser hereunder. 2.2 Notwithstanding anything contained in Paragraph 2.1 above to the contrary, if deliveries of volumes of Gas from any of the fields listed on Exhibit B give rise to an adjustment in Price under any Buyer's Marketing Agreement, then the price for any such volumes of Gas delivered by Seller during that month shall be a price per MMBtu equal to the applicable Price, with adjustments thereto on account of such deliveries pursuant to the terms of the applicable Buyer's Marketing Agreements for such Gas. 2.3 If, during the term of this Agreement, the index or trade publication cited in any Buyer's Sales Contract above ceases to exist or be published, the provisions of such Buyer's Sales Contract with respect to a replacement index or pricing mechanism for such Buyer's Sales Contract shall apply in determining the Price for Gas from such field hereunder. Otherwise, the Parties will endeavor to mutually agree to a replacement index or pricing mechanism for Gas from such field. In the event the Parties cannot agree to a replacement index or pricing mechanism for such Gas, then this Agreement shall terminate with respect to the purchase of Gas from such field at the end of the last Day for which an agreed upon price is applicable. 2.4 Subject to the terms of Section VII of Exhibit A, Prices paid by Buyer under this Article II are inclusive of severance tax reimbursement to Buyer. 2.5 The price payable for all volumes of Products of Processing which are redelivered for the account of Buyer after processing by Buyer's Processor, if any, shall be the Market Price per gallon then in effect for such Products of Processing. Seller shall have the right to elect, from time to time on prior written notice to Buyer and the relevant Buyer's Processor, to process or not process Seller's Gas for the recovery of Products of Processing in accordance with the terms and provisions of the respective Buyer's Processor's contract. 4 7 ARTICLE III. SELLER'S POINT(S) OF DELIVERY 3.1 The points of delivery from Seller to Buyer for each field listed on Exhibit B shall be the delivery point specified for such field as "Seller's Delivery Point" on such Exhibit. In the event Seller delivers or causes to be delivered Gas at any other delivery point, Buyer shall (to the extent it is reasonably able to under the Buyer's Marketing Agreements) accept delivery subject to a reduction in Net Price as provided in the definition of such term to compensate Buyer for the reasonable charges, if any, resulting therefrom, otherwise Buyer, or Buyer's designee, may elect not to accept delivery.
