          Re:  National Fuel Gas Company and Subsidiaries
               Form U-1 Application or Declaration (File No. 70-10074)
               -------------------------------------------------------

Ladies and Gentlemen:

     This opinion relates to the Application or Declaration, filed on July 18,
2002, as amended (as amended, the "Application-Declaration"), under the Public
Utility Holding Company Act of 1935, as amended (the "Holding Company Act"), by
National Fuel Gas Company, a New Jersey corporation ("National"), and each of
the following wholly-owned subsidiaries of National (collectively, the
"Subsidiaries"), National Fuel Gas Distribution Corporation ("Distribution"),
National Fuel Gas Supply Corporation, Horizon Energy Development, Inc. and its
subsidiaries, Highland Forest Resources, Inc., Leidy Hub, Inc., Data-Track
Account Services, Inc., Seneca Independence Pipeline Company, Seneca Resources
Corporation and its subsidiaries, Upstate Energy Inc., Niagara Independence
Marketing Company, National Fuel Resources, Inc. and Horizon Power, Inc.
Capitalized terms used but not defined in this opinion have the meanings
assigned thereto in the Application-Declaration.

     The Application-Declaration seeks authorization, from the effective date of
the order of the Securities and Exchange Commission (the "Commission") thereon
through December 31, 2005 for the financing and other transactions described in
summary form in Section 1.3 of the Application-Declaration and in greater detail
elsewhere in the Application-Declaration (collectively, the "Proposed
Transactions"). The Application-Declaration also relates to certain other
transactions over which National and the Subsidiaries have requested that the
Commission reserve jurisdiction.

     Based upon the foregoing and subject to the qualifications and assumptions
hereinafter specified, I am of the opinion that:

     1. The Subsidiaries are corporations duly organized and validly existing
under the laws of their respective jurisdictions of incorporation.

     2. If (i) the Proposed Transactions are consummated as contemplated by the
Application-Declaration and in accordance with the terms of the order or orders
of the Commission with respect thereto, all state securities or blue sky laws,
and, with respect to any securities registered with the Commission pursuant to
the Securities Act of 1933, as amended, the registration statement(s) relating
to such securities; (ii) the Boards of Directors of National and the
Subsidiaries, as the case may be, or duly appointed and authorized committees
thereof, or, in the case of certain securities, duly elected and authorized
officers thereof, approve and authorize, (a) each Proposed Transaction involving
National or a Subsidiary, as the case may be, and (b) each plan, agreement,
amendment, indenture, mortgage, deed of trust, supplemental indenture, officer's
certificate, guarantee and any and all other documents (together, "Operative
Documents") to be used in connection with each such Proposed Transaction; (iii)
each Operative Document (a) has been duly executed and delivered by National or
such Subsidiary, as the case may be, and, to the extent required, filed by
National, (b) if applicable, has been duly authorized, executed and delivered
by, and shall be the legal, valid and binding obligation of, each other party to
such Operative Document, including each Approved Counterparty, and (c) shall
have become effective; (iv) each security to be issued pursuant to the Proposed
Transactions shall have been duly executed, authenticated and delivered, as
appropriate, for the consideration contemplated; (v) the issuance of securities
by Distribution shall have been authorized by the Public Service Commission of
the State of New York and the Pennsylvania Public Utility Commission, if such
authorization shall have been required; (vi) each Financing Subsidiary and
Special Purpose Subsidiary shall be duly organized and validly existing under
the laws of its jurisdiction of organization; (vii) each debt security issued by
any such Financing Subsidiary or Special Purpose Subsidiary shall be a valid and
binding obligation of such issuer enforceable in accordance with its terms; and
(viii) no act or event other than as described herein shall have occurred
subsequent to the date hereof which would change the opinions expressed herein:

     (a) All state laws applicable to the Proposed Transactions involving the
Subsidiaries, as described in the Application-Declaration, will have been
complied with;

     (b) The debt securities, guaranties and other forms of credit support to be
issued by any Subsidiary and the Interest Rate Hedges and Anticipatory Hedges to
be executed and delivered by any Subsidiary will be valid and binding
obligations of such Subsidiary enforceable in accordance with their respective
terms, subject as to enforceability to (i) bankruptcy, insolvency,
reorganization, fraudulent transfer, fraudulent conveyance, moratorium or other
similar laws affecting the enforcement of creditors' rights and remedies, and
(ii) the application of general principles of equity (regardless of whether such
enforceability is considered in a proceeding in equity or at law) including,
without limitation (x) the possible unavailability of specific performance,
injunctive relief or any other remedy, and (y) concepts of materiality,
commercial reasonableness, good faith, fair dealing and equitable subordination;

     (c) National or any Non-Utility Subsidiary, as the case may be, will
legally acquire (i) the debt securities of direct and indirect Non-Utility
Subsidiaries and of Distribution, and (ii) the equity securities of Financing

Subsidiaries, Special Purpose Subsidiaries and, if applicable, reorganized
Non-Utility Subsidiaries; and

     (d) The consummation of the Proposed Transactions, as described in the
Application-Declaration, will not violate the legal rights of the holders of any
securities issued by National or any Subsidiary.

     I express no opinion as to (i) the subject matter jurisdiction of a federal
court to consider any dispute arising out of any Interest Rate Hedge or
Anticipatory Hedge, (ii) the provision of any Interest Rate Hedge or
Anticipatory Hedge to the extent such provision waives any objection by any
party to the laying of venue of any action or proceeding brought in any court
and any claim that any such action or proceeding has been brought in any
inconvenient forum or (iii) the enforceability of any provision of any Interest
Rate Hedge or Anticipatory Hedge relating to judgment currencies.

     In rendering the opinions expressed in paragraphs 2(b), and 2(d) hereof, I
have assumed that the issuance and sale of any long-term debt securities or
equity securities by National or any Subsidiary (including, without limitation,
Non-Utility Subsidiaries, Financing Subsidiaries and Special Purpose
Subsidiaries) will be in compliance with (i) all applicable restrictions set
forth in the respective Operative Documents, and (ii) so long as any debentures
or other evidences of indebtedness of National are outstanding under that
certain Indenture, dated as of October 15, 1974, as amended and supplemented (as
amended and supplemented, the "1974 Indenture"), between National and Irving
Trust Company (now The Bank of New York), as Trustee, all applicable
restrictions set forth in the 1974 Indenture.

     I am a member of the New York Bar and do not hold myself out as an expert
on the laws of any other state. Although I am not a member of the Bar of the
Commonwealth of Pennsylvania or the State of Delaware, I have studied the
relevant laws of those states in order to render certain of the opinions set
forth above. Accordingly, this opinion is expressly limited to the laws of such
jurisdictions as they relate to the matters covered herein.

     I hereby consent to the use and filing of this opinion as an exhibit to the
Application-Declaration.

                                           Very truly yours,

                                           /s/ Anna Marie Cellino

                                           Anna Marie Cellino
