      Subject to the terms, conditions and limitations hereof and
of  Pipeline's Rate Schedule FTS-7, and of the General Terms  and
Conditions,  transportation  service  hereunder  will  be   firm.
Subject  to the terms, conditions and limitations hereof  and  of
Pipeline's  Rate Schedule FTS-7, Pipeline agrees to  deliver  for
Customer's  account quantities of natural gas  up  to  Customer's

      Pipeline  shall  receive  for Customer's  account,  at  the
Customer  Point(s), for transportation hereunder daily quantities

MDQ.

      Pipeline shall receive for Customer's account, at  the  CNG

to  Customer's  MDQ, plus Applicable Shrinkage.   Pipeline  shall
transport  and  deliver for Customer's account, at  the  Customer

      Pipeline  shall  not  be  obligated  to,  but  may  at  its

of  gas  in  excess  of  the  applicable  Maximum  Daily  Receipt
Obligation  (MDRO),  plus  Applicable Shrinkage,  but  shall  not

                           ARTICLE II
                                
                        TERM OF AGREEMENT
                                
      This  Service Agreement shall become effective on  June  1,
1993, and shall continue in force and effect until April 15, 2000
and  from  year  to year thereafter unless terminated  by  either
party upon twenty-four months' prior written notice.  Subject  to
Section 22 of Pipeline's General Terms and Conditions and without
prejudice  to  such  rights,  this  Service  Agreement   may   be
terminated at any time by Pipeline in the event Customer fails to
pay  part  or all of the amount of any bill for service hereunder
and such failure continues for thirty (30) days after payment  is
due;  provided,  Pipeline gives thirty (30)  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  Pipeline  of  such  outstanding  bill.   Notwithstanding  the
foregoing,  service  shall  not be terminated  unless  and  until
Pipeline has received abandonment authority pursuant to Section 7
of  the Natural Gas Act.  Customer shall have the right to oppose
Pipeline's   application   to  the  Federal   Energy   Regulatory
Commission,   or  any  successor  agency,  for  such  abandonment
authority.   For  the  120  days following  termination  of  this
Service  Agreement, Pipeline shall utilize its  best  efforts  to
provide    Customer    with    such   additional    interruptible
transportation service, to be provided pursuant to Rate  Schedule
IT-1  or  successor of Rate Schedule IT-1, as  is  necessary  for
Customer to withdraw and receive delivery of all gas remaining in
storage pursuant to CNG's Rate Schedule GSS.

      Any portions of this Service Agreement necessary to correct
or  cash-out imbalances under this Service Agreement as  required
by  the  General  Terms  and Conditions of  Pipeline's  FERC  Gas
Tariff,  Volume  No.  1, shall survive the other  parts  of  this
Service  Agreement  until such time as such  balancing  has  been
accomplished.
