|3.1  At any time that the NEA Plant is operating at leastone combustion turbine using natural gas, Seller shall make available to Buyer at the Delivery Point the lesser of (i) 55% of all Flue Gas produced by the NEA Plant or (ii) an amount of Flue Gas containing carbon dioxide of sufficient quantities for Buyer to manufacture a maximum daily quantity of 192.5Tons of carbon dioxide per day; provided, however, that upon the exercise of Buyer's assumption obligations under the Three Party Agreement, Seller shall make available the lesser of (x) all Flue Gas produced by the NEA Plant or (y) an amount of Flue Gas containing carbon dioxide of sufficient quantities to manufacture a maximum daily quantity of 350 Tons of carbon dioxide per day. If any government regulatory permit which restricts the quantity of manufactured carbon dioxide to 350 Tons per day at the Facility is revised during the Initial Supply Period such that the quantity of manufactured carbon dioxide can be increased, then Seller will increase the quantity of Flue Gas to sufficient quantities to manufacture a maximum daily quantity of 350 Tons per day of carbon dioxide per day referenced in the preceding sentence proportionately to the increase in the allowed quantity of manufactured carbon dioxide permitted in the revised government regulatory permit. Upon such increase, Seller shall make available to Buyer at the Delivery Point 50% of all Flue Gas produced by the NEA Plant at any time that the NEA Plant is operating at least one combustion turbine using natural gas.

|(b)  If a party determines, after using all reasonable due diligence that disclosure of this Agreement or the filing of copies of this Agreement is required under any requirement of the Securities and Exchange Commission, such party will, to the maximum extent permitted by law, take all reasonable actions including, without limitation, requesting confidential treatment pursuant to the rules and regulations of the Securities and Exchange Commission of such Confidential Information to limit from any public disclosure such information under the Freedom of Information Act.

Upon the termination of this Agreement, the receiving party shall:  (i) promptly return all Confidential Information of the disclosing party to it, whether in written or electronic form, and neither receiving party nor any of its employees shall retain any copies, extracts, or other reproductions thereof, in whole or in part, in any form whatsoever; and (ii) take reasonable steps to assure that all documents, memoranda, notes, and other writings or electronic records prepared by it which include or reflect any Confidential Information belonging to the disclosing party and cannot be returned pursuant to (i) above, are destroyed.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
|(d)  Irreparable Harm.  Receiving party recognizes that disclosing party and its Affiliates, if relevant, may suffer irreparable harm as a result of the unauthorized disclosure, reproduction or use of any Confidential Information and that monetary damages will be inadequate to compensate disclosing party for such breach. Therefore, receiving party agrees that in the event of any failure to comply with the provisions of this Section, disclosing party shall be entitled to seek a preliminary injunction, and any other equitable relief in order to protect and recover the Confidential Information.

|9.1  In the event that a party to this Agreement has reasonable grounds to believe that the other party hereto has failed to fulfill any obligation hereunder, or, that its expectation of receiving due performance under this Agreement may be impaired, such party will promptly notify the other party in writing of the substance of its belief. The party receiving such notice must respond in writing within thirty (30) days of receipt of such notice and either provide evidence of cure of the condition specified, or provide an explanation why it believes that its performance is in accordance with the terms and conditions of this Agreement, and also specify three (3) dates, all of which must be within thirty (30) days from the date of its response, for a meeting to resolve the dispute. The claiming party will then select one (1) of the three (3) dates, and a dispute resolution meeting will be held. If the parties cannot in good faith discussions resolve their dispute, the parties will be free to pursue all remedies allowed under the law without prejudice.
