         federal  income tax on the same  amounts,  at the same times and in the

         NATIONAL FUEL GAS COMPANY,  a corporation  duly  organized and existing
under the laws of the State of New Jersey (herein  referred to as the "Company",
which term includes any successor Person under the Indenture  referred to on the
reverse hereof), for value received, hereby promises to pay to

or registered assigns, the principal sum of ____________________  Dollars on the
Maturity Date specified  above, and to pay interest thereon at the Interest Rate
specified above,  semi-annually on the Interest Payment Dates specified above of
each year and on the Maturity Date specified above,  from the Original  Interest
Accrual Date specified  above or from the most recent  Interest  Payment Date to
which interest has been paid, unless the Company shall default in the payment of
interest due on such Interest  Payment  Date,  in which case  interest  shall be
payable from the next preceding Interest Payment Date to which interest has been
paid,  or, if no  interest  has been paid on this  Security,  from the  Original
Interest  Accrual  Date.  In the event that any  Interest  Payment Date is not a
Business Day, then payment of interest  payable on such date will be made on the
next  succeeding  day which is a Business Day (and without any interest or other
payment in respect of such  delay)  with the same force and effect as if made on
such Interest Payment Date. The interest so payable, and punctually paid or duly
provided for, on any Interest  Payment Date will, as provided in the  Indenture,
be paid to the Person in whose name this  Security  (or one or more  Predecessor
Securities)  is registered  at the close of business on the Regular  Record Date
for such interest, which shall be the 15th day of the calendar month (whether or
not a Business Day) next preceding such Interest Payment Date; provided, that if
the  Original  Issue Date of this  Security  is after a Regular  Record Date and
before the  corresponding  Interest  Payment  Date,  interest so payable for the
period from and including the Original Issue Date to but excluding such Interest
Payment Date shall be paid on the next succeeding  Interest  Payment Date to the
Holder hereof on the related  Regular Record Date; and provided,  further,  that
interest payable at Maturity shall be paid to the Person to whom principal shall
be paid.  Any such  interest not so  punctually  paid or duly  provided for will
forthwith  cease to be payable to the Holder on such Regular Record Date and may
either  be paid to the  Person  in  whose  name  this  Security  (or one or more
Predecessor  Securities)  is  registered  at the close of  business on a Special
Record  Date  for the  payment  of such  Defaulted  Interest  to be fixed by the
Trustee,  notice of which shall be given to Holders of Securities of this series
not less than 10 days prior to such Special  Record Date, or be paid at any time
in any  other  lawful  manner  not  inconsistent  with the  requirements  of any
securities  exchange on which the  Securities of this series may be listed,  and
upon such notice as may be required by such exchange, all as more fully provided
in the Indenture.

                  Payment of the principal of (and premium, if any) and interest
on this Security will be made at the office or agency of the Company  maintained
for that purpose in The City of New York,  the State of New York in such coin or
currency  of the  United  States of  America  as at the time of payment is legal
tender for payment of public and private debts;  provided,  however, that (a) at
the option of the Company, interest on this Security may be paid by check mailed
to the address of the person entitled  thereto,  as such address shall appear on
the Security Register or by wire transfer to an account designated by the person
entitled thereto,  and (b) upon the written request of a Holder of not less than
$10 million in aggregate principal amount of Securities of this series delivered
to the  Company  and the Paying  Agent at least ten days  prior to any  Interest
Payment  Date,  payment of  interest on such  Securities  to such Holder on such
Interest  Payment Date shall be made by wire transfer of  immediately  available
funds to an account maintained within the continental United States specified by
such Holder or, if such Holder  maintains an account  with the entity  acting as
Paying Agent, by deposit into such account.

                  Reference  is hereby  made to the further  provisions  of this
Security set forth on the reverse hereof, which further provisions shall for all
purposes have the same effect as if set forth at this place.

                  Unless  the  certificate  of  authentication  hereon  has been
executed by the Trustee  referred to on the reverse hereof by manual  signature,
this  Security  shall not be entitled to any benefit  under the  Indenture or be
valid or obligatory for any purpose.

                      [FORM OF REVERSE OF MEDIUM-TERM NOTE]

                  This Security is one of a duly authorized  issue of securities
of the Company (herein called the "Securities"),  issued and to be issued in one
or more series under an Indenture (For Unsecured Debt  Securities),  dated as of
October 1, 1999 (herein,  together with any amendments or  supplements  thereto,
called the "Indenture", which term shall have the meaning assigned to it in such
instrument),  between the Company and The Bank of New York,  as Trustee  (herein

Indenture),  and reference is hereby made to the Indenture,  including the Board
Resolutions and Officer's Certificate filed with the Trustee on October 14, 1999

the Company, the Trustee and the Holders of the Securities and of the terms upon
which the  Securities  are, and are to be,  authenticated  and  delivered.  This
Security is one of the series  designated on the face hereof.  The acceptance of
this  Security  shall be deemed to  constitute  the consent and agreement by the
Holder hereof to all terms and provisions of the Indenture.

                  The Indenture  contains  provisions for defeasance at any time
of the entire  indebtedness  of the Company in respect of this Security,  or any
portion of the principal amount thereof, upon compliance with certain conditions
set forth in the Indenture, including the Officer's Certificate described above.

                  If an Event of  Default  with  respect to  Securities  of this
series shall occur and be  continuing,  the principal of the  Securities of this
series  may be  declared  due and  payable  in the  manner  and with the  effect
provided in the Indenture.

                  The  Indenture  permits,  with certain  exceptions  as therein
provided,  the  amendment  thereof  and  the  modification  of  the  rights  and
obligations  of the Company and the rights of the Holders of the  Securities  of
each series to be affected  under the  Indenture  at any time by the Company and
the Trustee with the consent of the Holders of a majority in principal amount of
the  Securities  at the time  Outstanding  of all  series  to be  affected.  The
Indenture  also  contains   provisions   permitting  the  Holders  of  specified
percentages  in principal  amount of the  Securities  of each series at the time
Outstanding, on behalf of the Holders of all Securities of such series, to waive
compliance  by the Company with certain  provisions of the Indenture and certain
past defaults  under the Indenture and their  consequences.  Any such consent or
waiver by the Holder of this Security  shall be conclusive and binding upon such
Holder and upon all future  Holders of this Security and of any Security  issued
upon the  registration  of  transfer  hereof or in  exchange  herefor or in lieu
hereof,  whether  or not  notation  of such  consent or waiver is made upon this
Security.

the Holder of this Security shall not have the right to institute any proceeding
with respect to the Indenture or for the appointment of a receiver or trustee or
for any other remedy  thereunder,  unless (a) such Holder shall have  previously
given the Trustee  written notice of a continuing  Event of Default with respect
to the  Securities  of this  series,  (b) the Holders of a majority in aggregate
principal  amount of the  Securities  of all series at the time  Outstanding  in
respect of which an Event of Default shall have occurred and be continuing shall
have made written request to the Trustee to institute  proceedings in respect of
such Event of Default in its own name as  Trustee,  (c) such  Holder  shall have
offered the Trustee reasonable  indemnity,  (d) the Trustee shall have failed to
institute any such proceeding for 60 days after receipt of such notice,  request
and offer of  indemnity,  and (e) the Trustee  shall not have  received from the
Holders of a majority in aggregate  principal amount of Securities of all series
at the time  Outstanding  in  respect  of which an Event of  Default  shall have
occurred  and be  continuing a direction  inconsistent  with such  request.  The
foregoing  shall not apply to any suit instituted by the Holder of this Security
for the  enforcement  of any  payment  of  principal  hereof or any  premium  or
interest hereon on or after the respective due dates expressed herein.

                  No reference  herein to the Indenture and no provision of this
Security  or of the  Indenture  shall  alter or  impair  the  obligation  of the
Company,  which is absolute and  unconditional,  to pay the principal of and any
premium and interest on this Security at the times,  place and rate,  and in the
coin or currency, herein prescribed.

form without coupons in denominations of $____. As provided in the Indenture and
subject to certain limitations therein set forth,  Securities of this series are

surrendering the same for such registration of transfer,  and exchangeable for a
like aggregate  principal  amount of Securities of this series and of like tenor
and of authorized  denominations,  as requested by the Holder  surrendering  the
same.

                  No service charge shall be made for any such  registration  of
transfer or exchange, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

                  The  Company,  the Trustee and any agent of the Company or the
Trustee may treat the Person in whose name this  Security is  registered  as the
absolute owner hereof for all purposes, whether or not this Security be overdue,
and  neither  the  Company,  the Trustee nor any such agent shall be affected by
notice to the contrary.

Indenture shall have the meanings assigned to them in the Indenture.
