SECOND AMENDED AND RESTATED
                        SPLIT DOLLAR INSURANCE AGREEMENT

         WHEREAS.  National  Fuel  Gas  Company  (hereinafter,  with  any of its
subsidiaries,  collectively called the "Company"),  in recognition of the highly
valued services of Gerald T. Wehrlin  (hereinafter called the "Executive"),  the
Executive's  importance  to  the  success  of  the  Company,  and  the  need  of
Executive's family for financial security in the event of Executive's death, has
authorized  the adoption of a split dollar  insurance  agreement  benefiting the
Executive; and

         WHEREAS,  the  Executive  and the  Company  desire to amend in  certain
respects  and to restate in its  entirety  the terms of the Amended and Restated
Split Dollar Insurance and Death Benefit  Agreement between them dated September
15, 1997,  as amended by an agreement  dated March 29, 1999;  which  Amended and
Restated  Agreement amended in certain respects and restated in its entirety the
agreement between them dated April 1, 199 1; and

         WHEREAS,   the  Executive  has  agreed  not  to   participate   in  any
noncontributory group term life insurance program while employed by the Company;
and

         WHEREAS,  the Company  desires to recover the  premiums it pays for the
purchase  of a life  insurance  policy  or  policies  for  these  purposes  upon
termination of this Agreement; and

         WHEREAS,  the  Executive  has assigned all of his interest in a certain
life insurance policy to his Trustees, as hereinafter more fully described.

         NOW THEREFORE,  for mutual  consideration,  the receipt and adequacy of
which the Company and Executive each acknowledge, the Company, the Executive and
the Trustees agree as follows:






I.       LIFE INSURANCE
         By an Irrevocable Trust Agreement dated January 26, 1999, the Executive
has  established a trust to which the Executive has assigned all of his interest
in a life insurance policy,  Policy Number 3485474  (hereinafter,  together with
any additional or replacement  policy and any supplementary  contracts issued in
connection  therewith,  called the  "Policy")  in the face  amount of  $711,529,
issued by the Guardian Life Insurance Company of America,  of New York, New York
(hereafter  called the  "Insurer").  The Trustee or Trustees acting from time to
time under such Trust Agreement (the "Trustees")  shall be the sole owner of the
Policy and may  exercise all rights and  incidents of ownership  with respect to
the Policy,  except as specifically  provided in this  Agreement.  To secure the
Company's interest under this Agreement, the Trustees have executed a collateral
assignment of the Policy to the Company (the "Collateral Assignment").

II.      PREMIUMS
         The Company  shall pay the total  premiums due on the Policy during the
term of this  Agreement.  Premiums  shall be paid  directly to the Insurer on or
before the due date,  extended by any grace period.  At the Company's  election,
Policy dividends may be applied to reduce premiums.  Notwithstanding  the above,
after the Executive  reaches age 65 or if the  Executive's  employment  with the
Company  terminates  prior  to such  age,  the  Company  shall  have no  further
obligation to make premium payments pursuant to this Section II.

III.     BENEFICIARY

         The Trustees may from time to time while this Agreement is in force, by
such  written  notice to the Insurer as the Insurer may require,  designate  the
beneficiary or beneficiaries (the "Beneficiary") to receive the Death Benefit as
provided in this Agreement.






IV.      TERMINATION OF AGREEMENT

         A. This  Agreement  shall  terminate  upon the earliest to occur of the
following:

                  a) January 1, 2008 (the Executive's 70th birthday), unless the
              Company and the Executive agree in writing to a later date;

                  b) mutual  agreement of the Company and the Executive prior to
              such date;

                  c) the Executive's death.

         B. If the  Executive's  employment  with the Company is terminated  for
Cause, as hereinafter  defined,  or if the Executive engages in Competition,  as
hereinafter defined, with the Company, whether or not the Executive's employment
with the Company has been  terminated,  the Company may terminate this Agreement
by  written  notice to the  Executive.  In the event of  termination  under this
Subsection B, the Executive shall forfeit all rights under this Agreement,  and,
notwithstanding anything in this Agreement, the Company shall be entitled to any
and all interests in the Policy.

V.       REPAYMENT OF PREMIUMS TO THE COMPANY
         Upon  termination of this  Agreement,  the Company shall be entitled to
repayment  of the amount of the total  premiums  paid by the Company to maintain
the  Policy,  less the  amount of any  distributions  therefrom  to the  Company
(including the outstanding balance of any Policy loans to the Company) (the "Net
Premiums").  Such repayment may be made in cash or, if this Agreement terminates
during  the  Executive's  lifetime,  in the  form  of a  paid-up  policy  having
equivalent value, as the Company may elect. If full repayment is not made within
60 days of  termination  of this  Agreement,  the Company may enforce its rights
under the Collateral  Assignment,  including (without  limitation) recovery from
the Insurer  out of the  proceeds of the Policy or by  surrender  thereof.  Upon
receipt of the Net Premiums,  the Company shall promptly  release the Collateral
Assignment.





VI.       DEATH BENEFIT WHILE AGREEMENT IS IN FORCE
         A. If this Agreement terminates by reason of the Executive's death, the
Beneficiary shall be entitled to receive from the proceeds of the Policy,  after
repayment of the Net Premiums,  an amount (the "Death Benefit") equal to the sum
of 24 times the base monthly  salary  payable by the Company to the Executive in
the month preceding the Executive's  death (or, if the Executive is retired,  in
the month prior to the  commencement of such  retirement) and two times the most
recent award,  if any, paid to the Executive under any of the Company's lump sum
payment programs  including the Annual At Risk  Compensation  Incentive  Program
(AARCIP).  Awards of  restricted  stock made to the Executive for service in the
Company's  fiscal  year 1996 or later to  supplement  an  AARCIP  award for that
fiscal  year,  which was  approximately  equal to the maximum  AARCIP award then
permissible  consistent with the shareholder  approval applicable to that AARCIP
award,  shall also be  included  in the  calculation  of the  Executive's  Death
Benefit at the rate of two times the most recent such award of restricted stock,
if any. The restricted  stock shall be valued at the average of the high and low
market value on the grant date. If the  Executive has retired (on  disability or
otherwise)  and  becomes   reemployed  by  the  Company,   the  latest  date  of
commencement  of  retirement  shall be used for purposes of computing  the Death
Benefit.  If the proceeds of the Policy after  repayment of the Net Premiums are
inadequate  to pay  the  Death  Benefit  in  full,  the  Company  shall  have no
obligation for the shortfall.

         B. The  Company  shall  notify  the  Insurer of the amount of the Death
Benefit within 30 days of the death of the Executive  while this Agreement is in
force,  and  the  Death  Benefit  shall  be paid to the  Beneficiary  under  the
settlement option elected by the Trustees or the Beneficiary.

         C. After payment of the Death Benefit, the Company shall be entitled to
any remaining  balance of the proceeds of the Policy,  and the Beneficiary,  the
Trustees and the  Executive's  estate  shall have no further  rights in or under
this Agreement or the Policy.





VII.     OTHER COMPANY BENEFITS
         The   Executive   shall   have  no   right   to   participate   in  any
non-contributory  group-term life insurance plan  maintained by the Company.  In
other respects,  the benefits provided to the Executive under this Agreement and
the Policy shall be separate from and in addition to other  benefits that may be
offered  by  the  Company  to  the  Executive,  including  any  non-contributory
accidental death and dismemberment coverage that the Company maintains.

VIII.    POLICY LOANS
         While this Agreement is in force, neither the Trustees nor any Assignee
shall borrow against or pledge the Policy as security for any debt.

IX.      ASSIGNMENT OF THE POLICY AND THIS AGREEMENT
         A. The Policy may not be assigned, transferred, pledged, surrendered or
otherwise  encumbered or alienated  without the written  consent of the Company.
Any assignee pursuant to this Section and any other successor to the Executive's
interest  in the Policy  (both  referred to herein as the  "Assignee")  shall be
bound by this restriction.

         B. The rights and  obligations  of this  Agreement  are personal to the
Executive  and  the  Trustees  and  may not be  assigned;  however,  one or more
successor Trustees may be appointed.

X.       REPLACEMENT OF THE POLICY
         The  Company  shall  have the night to replace  the  Policy  with a new
policy or policies,  with the consent of the Executive  and the Trustees,  which
consent shall not  unreasonably be withheld.  In the event of such  replacement,
the  Company  shall have the right to receive  the cash  surrender  value of any
policy being canceled or surrendered.





XI.      AMENDMENT
         This  Agreement  may be altered,  amended or modified only by a written
Agreement  signed by the Company,  the  Executive  and the Trustees  (or, if the
Policy has been  assigned,  the  Assignee).  This  Agreement and any  amendments
hereto  shall be binding upon the Company,  the  Executive  and the Trustees and
their legal representatives, successors, beneficiaries and assigns. In the event
that the Company becomes a party to any merger, consolidation or reorganization,
this  Agreement  shall remain in full force and effect as an  obligation  of the
Company or its successors in interest.

XII.     DEFINITION OF TERMS
         A.  "Cause"  means  serious,  willful  misconduct  in  respect  of  the
Executive's  obligations  to the Company that has damaged or is likely to damage
the Company,  including  (without  limitation)  any  endeavor by the  Executive,
directly or indirectly,  to interfere in the business  relations of or otherwise
harm the Company, as the Company shall reasonably determine.

         B.  "Competition"  means any employment,  consulting  contract or other
arrangement,  before or after the termination of the Executive's employment with
the  Company,  with any person or entity  that is then or  becomes  engaged in a
business  enterprise of any sort that is, in any material  respect,  competitive
with the Company,  or any assistance by the Executive to any such  enterprise in
engaging in such competition.

XIII.    NONINTERFERENCE
         The  Executive  and the  Trustees  covenant  that  the  Executive,  the
Trustees,  any  Assignee  and the  Beneficiary  shall  not  interfere  with  the
Company's  rights under this Agreement or take any voluntary  action that causes
the Policy to fall or lapse,  in whole or in part. The Executive,  the Trustees,
any Assignee and the Beneficiary  will cooperate with Company and the Insurer in
all respects in obtaining and  maintaining  the Policy and shall,  if necessary,
use their best efforts





to provide,  from time to time, such evidence of insurability as the Insurer may
require.

XIV.     MISCELLANEOUS
         A. If any  part of this  Agreement  or the  application  of any part to
certain  persons  or  circumstances  shall  be  invalid  or  unenforceable,  the
remainder of the Agreement shall continue to be effective.

         B. This  Agreement  shall be construed and regulated  under the laws of
the State of New York.

         C. The  Executive  understands  that the benefits  provided  under this
Agreement will or may result in taxable  income to him and the Company  reserves
the right to implement tax  withholding  respecting  such amounts as and when it
may deem such withholding appropriate.

XV.      ERISA PROVISIONS
         This  Agreement  constitutes  part of a welfare  benefit plan ("Welfare
Plan") and, as such, the following provisions are part of this Agreement and are
intended to meet the requirements of Title I of the Employee  Retirement  Income
Security Act of 1974 ("ERISA"):

         1.       The named fiduciary of the Welfare Plan is the Company.

         2.       The  funding  policies  under  the  Welfare  Plan are that all
                  premiums  on the  Policy be  remitted  to the  Insurer  by the
                  Company when due, less any amount paid by the  Executive,  the
                  Trustees, or the Assignee, in their sole discretion.

         3.       Direct  payment  by the  Insurer  is the basis of  payment  of
                  benefits under this Agreement.

         4.       For claims procedure  purposes with respect to claims asserted
                  under the Welfare Plan,  the "Claims  Manager" shall be Robert
                  J. Dauer,  or such other person as may be designated from time
                  to time by the Company.





                 a.        If for any reason a claim for  benefits  is made by a
                           participant  under the Welfare Plan  ("Claimant") and
                           is denied by the Company,  the Claims  Manager  shall
                           deliver  to  the   Claimant  a  written   explanation
                           specifying the reasons for the denial, the provisions
                           on which such denial is based, such other data as may
                           be  pertinent,  and the  procedures  available to the
                           Claimant to obtain  review of the claim,  all written
                           in a  manner  calculated  to  be  understood  by  the
                           Claimant. For this purpose,

                 (i)       the claim shall be deemed filed when presented in
                           writing to the Claims Manager; and

                 (ii)      the Claims Manager's  explanation shall be in writing
                           delivered to the Claimant  within 90 days of the date
                           the claim is filed.

                 (b)       The Claimant shall have 60 days following  receipt of
                           the  denial  of the  claim to file  with  the  Claims
                           Manager a written  request  for review of the denial.
                           For  such   review,   the  Claimant  or  his  or  her
                           representative  may submit  pertinent  documents  and
                           written issues and comments.

                 (c)       The Claims  Manager  shall have  discretion to decide
                           the issue on review and shall  furnish  the  Claimant
                           with a  copy  of  the  decision  within  60  days  of
                           receiving  the  Claimant's  request for review of the
                           claim.  The  decision on review shall be written in a
                           manner  calculated  to be  understood by the Claimant
                           and shall  specify the reasons for the  decision,  as
                           well as the  provisions  on  which  the  decision  is
                           based.  If a copy of the decision is not so furnished
                           to the Claimant  within such 60 days, the claim shall
                           be deemed denied on review.






         IN WITNESS  WHEREOF,  the parties have executed  this  Agreement on the
