       Maximum Daily Receipt Obligation for such Point of Receipt plus  the
       applicable  Fuel Reimbursement Quantity; and provided  further  that

                                ARTICLE II
                             TERM OF AGREEMENT
                                     
   2.1 This  Agreement  shall become effective as of  the  date  set  forth
       hereinabove and shall continue in effect for a term ending March 31,
       2012  ("Primary Term") and shall remain in force from year  to  year

       year  or more prior to the end of the Primary Term or any successive
       term  thereafter.  Algonquin's right to cancel this  Agreement  upon
       the  expiration  of the Primary Term hereof or any  succeeding  term

       of the General Terms and Conditions.

   2.2 This  Agreement  may be terminated at any time by Algonquin  in  the
       event  Customer fails to pay part or all of the amount of  any  bill

       after  payment  is  due; provided Algonquin  gives  ten  days  prior
       written  notice to Customer of such termination and provided further
       such  termination shall not be effective if, prior to  the  date  of
       termination, Customer either pays such outstanding bill or furnishes
       a  good and sufficient surety bond guaranteeing payment to Algonquin
       of  such  outstanding  bill; provided that Algonquin  shall  not  be
       entitled  to terminate service pending the resolution of a  disputed
       bill  if  Customer  complies  with  the  billing  dispute  procedure
       currently on file in Algonquin's tariff.

       Algonquin's  existing FERC Gas Tariff as may be found  necessary  to
       assure  that the provisions in (a), (b), or (c) above are  just  and
       reasonable.
