SERVICE AGREEMENT
                                 (ESS Service)

          AGREEMENT made this 19th day of September 1995, by and between
NATIONAL FUEL GAS SUPPLY CORPORATION, a Pennsylvania corporation, hereinafter
called "Transporter", and NATIONAL FUEL GAS DISTRIBUTION CORPORATION,
hereinafter called "Shipper".

          WITNESSETH:  That, in consideration of the mutual covenants herein
contained, the parties hereto agree that  Transporter will store natural gas for
Shipper during the term, at the rates and on the terms and conditions
hereinafter provided.


                                   ARTICLE I

                                   Quantities

          Beginning on the date on which storage service is commenced hereunder
and thereafter for the remaining  term  of  this  Agreement,  and  subject  to
the  provisions  of Transporter's ESS Rate Schedule, Transporter agrees to cause
to be injected into storage for Shipper's account, store, and withdraw from
storage,  quantities of natural gas as follows:

         Maximum Storage Quantity (MSQ) of 2,000,000 Dekatherms (Dth)
         Maximum Injection Quantity (Contract MDIQ) of 11,765 Dth
         Maximum Withdrawal Quantity (Contract MDWQ) of 13,245 Dth


                                   ARTICLE II

                                      Rate

          Unless otherwise mutually agreed in a written amendment to this
Agreement, or unless a different rate is specified in the release forms attached
hereto, for each dekatherm of gas transported for Shipper by Transporter
hereunder, Shipper shall pay Transporter the maximum rate provided under Rate
Schedule ESS set forth in Transporter's effective FERC Gas Tariff.  In the event
that the Transporter places on file with the Federal Energy Regulatory
Commission ("Commission") another rate schedule which may be applicable to
transportation service rendered hereunder, then Transporter,  at its option, may
from and after the  effective  date of such  rate  schedule,  utilize  such rate
schedule in performance of this  Agreement.  Such a rate  schedule(s)  or

<PAGE 2>

superseding  rate schedule(s) and any revisions  thereof which shall be filed
and become effective shall apply to and be a part of this Agreement. Transporter
shall have the right to propose,  file and make effective with the  Commission,
or other body having jurisdiction, changes and revisions of any effective rate
schedule(s), or to propose, file, and make effective superseding rate schedules,
for the purpose of changing the rate, charges, and other provisions thereof
effective as to Shipper.

          Shipper agrees to reimburse Transporter for the filing fees associated
with this service and paid to the Commission.


                                   ARTICLE III

                                Term of Agreement

          This Agreement shall be effective as of January 1996, and shall
continue in effect until April 15, 2006, and shall continue in effect thereafter
until terminated by either  Shipper or Transporter effective as of April 1 of
any year, upon twelve (12) months' written notice to the other.


                                    ARTICLE IV

                               Regulatory Approval

          Performance under this Agreement by Transporter and Shipper shall be
contingent upon  Transporter and Shipper receiving all necessary regulatory or
other governmental approvals upon terms satisfactory to each.  Should
Transporter and Shipper be denied such approvals to provide the service
contemplated herein or construct  and  operate any  necessary  facilities
therefor  upon the terms and conditions  requested  in  the  application
therefor, then Transporter's and Shipper's obligations hereunder shall
terminate.

          In particular, performance under this Agreement shall be contingent
upon permanent certification of Transporter's storage facilities at Allegany
State Park.


                                     ARTICLE V

                  Incorporation By Reference of Tariff Provisions

          To the extent not inconsistent with the terms and conditions of this
Agreement, the provisions of Rate Schedule ESS, or any effective superseding
rate schedule or otherwise  applicable rate schedule,  including any provisions
of the General Terms and Conditions incorporated therein, and any revisions

<PAGE 3>

thereof that may be made effective hereafter are hereby made applicable to and a
part hereof by reference.


                                    ARTICLE VI

                                   Miscellaneous

                  1. No change,  modification  or alteration  of this  Agreement
shall be or become  effective  until executed in writing by the parties  hereto,
and no course of dealing  between the parties  shall be  construed  to alter the
terms hereof, except as expressly stated herein.

                  2. No waiver by any party of any one or more  defaults  by the
other in the performance of any provisions of this Agreement shall operate or be
construed as a waiver of any other default or defaults,  whether of a like or of
a different character.

                  3. Any company  which  shall  succeed by  purchase,  merger or
consolidation of the gas related  properties,  substantially as an entirety,  of
Transporter  or of Shipper,  as the case may be, shall be entitled to the rights
and shall be subject to the  obligations of its  predecessor in title under this
Agreement.  Either party may, without  relieving itself of its obligations under
this Agreement, assign any of its rights hereunder to a company with which it is
affiliated,  but  otherwise,  no assignment  of this  Agreement or of any of the
rights or obligations hereunder shall be made unless there first shall have been
obtained the consent thereto in writing of the other party. Consent shall not be
unreasonably withheld.
