                        REPORT OF INDEPENDENT ACCOUNTANTS






To the Board of Directors and
Shareholders of
National Fuel Gas Company

In our  opinion,  the  consolidated  financial  statements  listed  in the index
appearing under Item 10 on Page 32 present fairly, in all material respects, the
financial  position  of  National  Fuel  Gas  Company  and its  subsidiaries  at
September 30, 1997, and the results of their operations and their cash flows for
the  year  then  ended,  in  conformity  with  generally   accepted   accounting
principles.  These financial  statements are the responsibility of the Company's
management;  our  responsibility  is to express  an  opinion on these  financial
statements  based on our audit.  We conducted  our audit of these  statements in
accordance with generally accepted auditing standards which require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements,  assessing the accounting  principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for the opinion  expressed
above.

Our audit was made for the  purpose of  forming  an opinion on the  consolidated
financial statements taken as a whole. The consolidating information on Pages 35
through 58 is  presented  for  purposes of  additional  analysis  rather than to
present  financial  position,  results  of  operations  and  cash  flows  of the
individual companies. Accordingly, we do not express an opinion on the financial
position,  results of  operations  and cash flows of the  individual  companies.
However, the consolidating information on Pages 35 through 58 has been subjected
to the auditing  procedures  applied in the audit of the consolidated  financial
statements  and, in our opinion,  is fairly  stated in all material  respects in
relation to the consolidated financial statements taken as a whole.

                the  Partnership  pursuant  to the NGPLIP  Agreement  or the SIP
                Agreement,  as the case may be, or if either MidCon  Participant
                or NF  Participant  does  not  receive  requisite  Board  or SEC
                approval(s),  as the  case  may  be,  MidCon  Participant  or NF
                Participant shall withdraw from the Marketing Partnership.  Upon

                will only be entitled to a return of its capital  account in the
                Marketing  Partnership  if its Affiliate is entitled to a return
                of its Capital Account in the Partnership  which return shall be
                made  at the  same  time  its  Affiliate's  Capital  Account  is

                account  due  to  its   failure  to  make  a  required   capital
                contribution, such Participant shall contribute to the Marketing

                within sixty (60) days after the date of withdrawal.

                increased pro rata so that the total of all ownership  interests
                continues to be 100% after such withdrawal.

make any such  confidential  information  (other than its own)  available to any
unauthorized  Person without the prior written consent of the other Participants

harm. Accordingly,  the Participants agree that the injured Participant shall be
entitled,  in  addition  to other  remedies  which  may be  available  to it, to
immediate injunctive relief from any material breach of any of the provisions of

                                  INTRODUCTION

     This  relocation  policy manual has been  developed to assist you with your
move. It includes  information  regarding all of the  necessary  procedures  and
focuses on  providing  a complete  description  of your  entitlements.  New York
relocations  will  be  coordinated  by  Richard  J.  Miga  in the  Buffalo  Land
Department and Pennsylvania  relocations will be coordinated by Kevin J. Karg in
the  Erie  Land  Department   (hereinafter   referred  to  as  "your  relocation
coordinator"). Any questions should be addressed to your relocation coordinator.

     We are  cognizant of the fact that a relocation  involves  your family.  In
particular,  we want to include your spouse as an integral  part of the process.
The goal of the  company  relocation  policy is to enable you and your family to
relocate  with  minimal  inconvenience  and  without  unnecessary  expense.  The
function of this  manual is to provide  step by step  guidelines  to ensure that
these objectives will be attained.

     On behalf of the  management of National Fuel, we extend our best wishes to
you on your relocation and are ready to help you along the way.


            Step 1 - Initial Meeting with Your Relocation Coordinator

     Once officer approval has been given for your transfer, please contact your
relocation  coordinator at your earliest  convenience to schedule a meeting. The
initial  meeting  will  provide  you with the  opportunity  to review all of the
relocation steps with your relocation coordinator.


                         Step 2 - The Appraisal Process


     In order to determine the market value of your home, two appraisals must be
conducted.  One  certified  appraiser  is  chosen  by you and one is  chosen  by
National Fuel. National Fuel will pay the fees

<PAGE>


for  both  appraisals.  If  there  is a wide  disparity  in the two  appraisals,
National Fuel may arrange for a third  appraisal and consider it in place of the
appraisal that is, in National  Fuel's  judgment,  inaccurate.  Your  relocation
coordinator can provide you with a list of several certified  appraisers in your
geographical area. Do not select an appraiser you are considering as a potential
listing agent because that could result in a conflict of interest for the agent.
The two  appraisals  will be averaged to  determine  the  "market  value"  which
enables you to offer your home at a fair and marketable suggested listing price.
In addition, this figure will enable you to determine the net equity you have in
your home.  (Net  equity  equals  the  average  of the two  appraisals  less any
outstanding mortgages or home equity loans or liens).

     Once you know the value of your home and the underlying equity, you will be
able to make an  informed  decision  about the price range of home you should be
looking  for  at  your  new  location.  It is  important  to  remember  that  no
consideration  will be  given  by  National  Fuel if you  move to a more or less
expensive  residence,  or  because of  disparate  property  values in  different
geographical areas.

     * Please  remember to provide your  relocation  coordinator  with a copy of
your appraisal in a timely manner. Your relocation  coordinator will provide you
with a copy of the appraisal which National Fuel receives as well.

                      Step 3 - Selecting a Listing Realtor

     After the  appraisals  have  been  completed,  you will  need to  contact a
Realtor to have your home listed. If you sell the home through a board certified
Realtor,  the sales  commission  will be reimbursed by National Fuel. If you are
uncertain about choosing a Realtor, your relocation coordinator will provide you
with a list of several Realtors in your geographical area.

          Step 4 - Entering Into a Listing Agreement With Your Realtor


     Most listing agreements are standardized,  but please feel free to ask your
relocation  coordinator  about any uncertainty  you may have regarding  specific
terms and conditions of the agreement.  National 

<PAGE>

Fuel has a reimbursement cap of 6% on Realtors'  commissions.  If your Realtor's
standard commission exceeds 6%, you have the following options:

         1) Negotiate  with your Realtor to lower the rate to 6% (most  Realtors
         are agreeable to this reduction);

         2) Pay the additional commission yourself;

         3) Select another Realtor.

     The following provisions must appear in your listing agreement:

         1) The term must not exceed 90 days; and

         2) This exact language:

              "In the event  National  Fuel Gas Company or any of
         its subsidiaries  elects to purchase this residence,  it
         is  understood   and  agreed  that  there  shall  be  no
         commission or fees of any nature payable to the Realtor,
         agency and/or associates involved with this residence."

     Be careful about  determining  a listing price for your home.  Keep in mind
that National  Fuel may purchase  your home,  but only after it is listed with a
Realtor and if it does not sell within 90 days after the listing agreement date.
If during the above three-month period you receive a purchase offer at less than
the market value, the company may, subject to Senior Officer  approval,  pay the
difference to consummate the sale.

     Your Realtor may provide you with a booklet outlining some helpful hints to
prepare your home for showings. In most instances these cosmetic adjustments may
be made at a small expense;  however, National Fuel does not reimburse for these
types of expenses.


<PAGE>





               Step 5 - Purchase of Your Home by National Fuel or,

                 in the Alternative, Request for an Equity Loan

         If your home does not sell in 90 days, National Fuel will purchase your
home for its market value (see Step 2 - The Appraisal Process). If National does
purchase the home, the amount you receive will be:

         THE AVERAGE OF TWO APPRAISALS (MARKET VALUE)

         LESS:    ANY OUTSTANDING MORTGAGE, HOME EQUITY LOAN BALANCE, OR LIEN

         LESS:    3% REALTOR COMMISSION (HALF STANDARD BROKER'S FEE)
         ----------------------------------------------------------

         =        NET AMOUNT YOU WILL RECEIVE


         In the  alternative,  National  Fuel will,  at your  request,  consider
loaning  to you,  on a  demand  note at no  interest,  money  in an  amount  not
exceeding your equity in the home being sold.  This loan amount is calculated by
determining the market value of the property, less the amount of any outstanding
mortgages. Such demand note is to be repaid:

                  1)  within 30 days after the sale of your home, and

                  2)  not more than one year from the date the loan was made, or

                  3)  upon demand by National Fuel.

When an equity loan is provided  National Fuel may,  after the expiration of the
90 day listing period and upon your request,  make mortgage  payments to support
the residence until it is sold.

                Step 6 - Policy for Reimbursement of Expenses for

                        Transferred Supervisory Employees


         National Fuel shall reimburse  relocation  expenses for supervisors who
are requested by the company to change their place of residence as follows*:

                  1)  Living  expenses.  Living  expenses  for you at  your  new
                      ----------------
                  location for a duration to be  determined  by the  appropriate
                  Senior Officer in accordance with the following:

                           a)  Payment will be made for sleeping accommodations

                           b)  Payment  for  meals,  breakfast,  supper and also
                  lunch when this is in accordance with National Fuel's policy.

                           c)   Payment   for   or   provision   of   round-trip
                  transportation  home not more often than once a week.

                  2)  Costs  associated  with  sale of  existing  residence  and
                      ----------------------------------------------------------
                  purchase of new  residence.  Costs that are incurred  when you
                  --------------------------
                  sell your existing  residence and purchase a new residence are
                  reimbursed in accordance with the following:

                           a)  Mortgage  rate   differential.   Because  of  the
                               -----------------------------
                  potential  disparity  between  mortgage  rates  at the time of
                  relocation and historical rates,  National Fuel will pay, when
                  applicable,  annually to you, for the three years beginning on
                  the first  anniversary of the move, a cash allowance  equal to
                  the interest  rate on the new mortgage  less the interest rate
                  on your prior  mortgage (on the  residence  being moved from),
                  times the principle balance remaining on the prior mortgage at
                  the time of the  transfer.  If you are no longer in the employ
                  of National  Fuel or sell the new house  before the end of the
                  three-year period,  the allowance will immediately  terminate.
                  You  must  provide  the  relocation  coordinator  with  a bank
                  statement  indicating the interest rate and mortgage  balance.
                  This allowance will be treated as ordinary income.


- - -------------------
*All  expenses  associated  with the  relocation  should  be  submitted  to your
relocation coorindator for reimbursement.

                           b)  Closing  expenses.  National  Fuel will  pay,  in
                               -----------------
                  connection  with the transfer,  within one year of the date of
                  the  transfer,  the  "Reimbursable   Expenses"  set  forth  on
                  Appendix A. Immediately after the closing,  you should provide
                  closing   statements  to  the   relocation   coordinator   for
                  appropriate reimbursement.

                           c) Salary allowance.  You will be paid a five percent
                              ----------------
                  (5%)  allowance on salary in effect at the time of transfer in
                  the year of the  transfer,  and a two and one-half  percent (2
                  1/2%)  allowance  in  the  subsequent  year,  payable  on  the
                  anniversary of the move, to cover the  incidental  expenses of
                  the  required  move.  These  allowances  will  be  treated  as
                  ordinary income. 

                  3) House-hunting expenses. Payment for any reasonable expenses
                     ----------------------

                  location.  Reimbursable  expenses include  mileage,  meals and
                  hotel.

                  4) Household moving costs.  Reasonable  direct moving costs of
                     ----------------------
                  furniture and personal possessions, including mileage, packing
                  and  necessary  unpacking  charges,  in  accordance  with  the
                  following:

                           a) You should  receive a cost  estimate from at least
                  two reputable moving companies and, unless otherwise  directed
                  by National Fuel,  select the moving company which submits the
                  least  expensive  estimate.  National Fuel may, at its option,
                  receive a cost estimate from an additional  moving company and
                  require you to select such company.

<PAGE>

                           b) The  moving  company's  bill  will be paid  either
                  directly by National  Fuel or you may pay the bill and present

                                   APPENDIX B

                               TAX CONSIDERATIONS

         In general,  certain moving expense  reimbursements are excludable from
an employee's income if the following conditions are met:

               The expenses must be incurred in connection with the commencement
               of work at a new location.

               The employee's  commute to the new place of work must be at least
               50 miles farther than the employee's  commute from his or her old
               residence, and;

               The  employee  must work in the new  location for 39 weeks during
               the 12-month period following the move.

                            QUALIFIED MOVING EXPENSES

         Qualified moving expenses incurred by and reimbursed either directly to
or indirectly for an employee are excluded from Gross Income on Form W-2.

         Qualified moving expenses are:

               Traveling  expenses,   (including   Lodging),   from  the  former
               residence to the new residence, and;

               Moving  expenses for  transporting  household  goods and personal
               effects from the former residence to the new residence.


                          NON-QUALIFIED MOVING EXPENSES

         Reimbursements relating to non-qualified moving expenses are includable
as income to the employee.  Non-qualified moving expenses are any expenses other
than qualified  moving  expenses  incurred by or reimbursed  either  directly or
indirectly  in  association  with a move.  To offset the increased tax liability
related to such  reimbursements,  National  Fuel will  "gross up" these  expense
reimbursements  except for the interest rate  differential and salary allowance,
so  that  any  additional  tax  liability  relating  to  such  reimbursement  is
minimized.  (If questions  arise regarding this "gross up"  calculation,  please
contact the Payroll Department.) Non-qualified moving expenses include the 
following:

               Salary  Allowance - 5% first year and 2 1/2% second year 

               Interest Rate  Differential  

               Storage  Charges  

               Purchase of the  employee's residence

               Expenses  associated  with the sale of the old or purchase of the
               new residence 

               Cost of meals or other  personal  costs  reimbursed

               Reasonable   expenses   associated   with  house  hunting  visits
               
               Temporary  living expenses - if applicable  

               Expenses  incurred in the settling of an  unexpired  lease or the
               acquisition  of a new  lease  on  property  to be used as the new
               residence - if applicable

         These expense  reimbursements  will be grossed-up for tax purposes with
the exception of the Salary Allowance and Interest Rate Differential.

         There may be other  non-qualified  expenses  associated with moving. If
you have any questions, please contact your relocation coordinator.






                        AGREEMENT PURSUANT TO RULE 45 (c)
                        ---------------------------------

                  UNDER THE PUBLIC UTILITY HOLDING ACT OF 1935
                  --------------------------------------------



         WHEREAS,   National  Fuel  Gas  Company  ("National"),   a  corporation
organized  under the laws of the State of New  Jersey and a  registered  holding
company under the Public Utility Holding  Company Act of 1935 ("Act"),  together
with its wholly-owned subsidiaries, listed below:

         National Fuel Gas Distribution Corporation
         National Fuel Gas Supply Corporation
         Seneca Resources Corporation
         Leidy Hub, Inc.
         Highland Land & Minerals, Inc.
         Utility Constructors, Inc.
         Data-Track Account Services, Inc.
         National Fuel Resources, Inc.
         Horizon Energy Development, Inc.
         Seneca Independence Pipeline Company
         Niagara Energy Trading Inc.
         Niagara Independence Marketing Company

join annually in the filing of a consolidated federal income tax return; and

         WHEREAS,   it  is  the  intention  of  National  and  its  subsidiaries
(hereinafter  collectively  referred  to as the  "System"),  to enter into a Tax
Agreement for the allocation of current federal income taxes; and

         WHEREAS,  Rule 45 (c) of the Act has been adopted by the Securities and
Exchange  Commission  with the  specific  intention  of  providing  a method  of
allocation of consolidated  federal income taxes by a registered holding company
and its subsidiaries;

         NOW,  THEREFORE,  the System  does hereby  covenant  and agree with one
another that the consolidated current federal income tax liability of the System
shall be  allocated  pursuant to Rule 45 (c) of the Act, so that each company of
the System will benefit mutually from the application of said Rule, as follows:

<PAGE>

         FIRST:  There shall be allocated  and preserved to each company the tax
effects of its own capital gains or losses which shall be subject to the capital
gains rate, if applicable, its tax credits,  investment tax credit recapture and
the effects of any other  material  items taxed at different  rates or involving
special  benefits  or  limitations  as may  result  from  an  unexpected  event,
including  changes to the  Internal  Revenue Code which may be  applicable  to a
particular company, including its carry-over amounts to the extent those amounts
are absorbed in the taxable year.

         SECOND:  After giving  effect to the special  allocations  described in
paragraph  First above,  the balance of the current tax  liability of the System
shall  be  allocated  to each  System  company  on the  basis  of each of  their
respective  contributions of corporate taxable income to the total  consolidated
taxable  income of the  System,  excluding  income  subject to  taxation  at the
capital gains rate, if applicable. The tax attributable to such income will have
been separately allocated pursuant to paragraph First above. However, so long as
National has negative  corporate  taxable income,  no portion of the current tax
liability shall be allocated to National as a corporate tax credit. Instead, the
negative corporate taxable income of National shall be allocated to those System
companies which have positive  corporate taxable income, on the basis of each of
these companies'  contribution of positive corporate taxable income to the total
positive  corporate taxable income of the System. The tax allocated to a company
under this  paragraph,  which may be either  positive  or  negative  (except for
National)  shall be equal to the  consolidated  tax  liability  multiplied  by a
fraction, the numerator of which is the positive corporate taxable income of the
Company (as adjusted by National's  negative  corporate taxable income described
in  this  paragraph  Second  above  and in  paragraph  Third);  or the  negative
corporate  taxable  income of the Company  (as  adjusted  in  paragraph  Third),
including any carry-over loss attributable to the Company to the extent absorbed
in the taxable year, and the  denominator of which is the  consolidated  taxable
income of the System (as adjusted in paragraphs First and Third). Companies with

<PAGE>

taxable  income  will be  allocated  a tax  liability  under this  method  while
companies with net operating  losses  (except  National) will be allocated a tax
benefit or credit.

         THIRD:  The tax effect of intercompany  transactions  eliminated in the
calculation  of  consolidated  taxable  income  shall  be  eliminated  from  the
corporate  taxable income of the companies  involved in such transactions in the
calculations provided in paragraph Second.

         FOURTH:   Any   consolidated   alternative   minimum   income  tax  and
environmental tax arising from consolidated  alternative  minimum taxable income
(AMTI)  will be  allocated  among  the  companies  on the basis of each of their
respective  contributions  of positive  AMTI to the total  positive  AMTI of the
System.

         FIFTH:  Under the method of allocation  described in  paragraphs  First
through Fourth above, the companies agree that the tax allocated to each company
(except  National) shall not exceed the amount of tax of such company based upon
a separate  return  computed as if such company had always filed its tax returns
on a separate  return  basis.  However,  in computing  the  separate  return tax
liability of a company,  items of  carry-forward,  carry-back  and  intercompany
transactions, to the extent that any or all of these items have been utilized by
the System in a prior taxable year's allocation, will be disregarded in order to
comply with the separate return  limitation  provisions set forth in Rule 45 (c)
of the  Act and  regulations  promulgated  under  Section  1552 of the  Internal
Revenue  Code.  Thus,  to the extent  that a company  receives a tax  benefit or
credit  pursuant to  paragraph  Second  above,  such  benefit or credit would be
applied to reduce any tax credits in future  years to which such  company  might
otherwise  become  entitled under the separate return  limitation  provisions of
Rule 45 (c) of the Act and  regulations  promulgated  under  Section 1552 of the
Internal Revenue Code.

<PAGE>


         IT IS FURTHER AGREED by and among the System as follows:

         I.  PAYMENTS:  It is agreed  that those  companies  allocated a current
             --------
federal income tax liability under this agreement will pay the Internal  Revenue
Service a portion of that  liability in the amounts and on the dates directed by
National,  as determined and pursuant to the applicable sections of the Internal
Revenue Code.  Another  portion of the current  federal  income tax liability of
those  companies  shall  be  paid  by them to the  other  companies  which  were
allocated a tax benefit.  Such  payments will also be made in the amounts and on
the dates directed by National.

         II.  SEPARATE RETURN  LIABILITY:  The System intends that the result of
              --------------------------
the proposed method of allocation and payment will be:

         (a) No company will pay more than its separate  return  liability as if
         it had always filed separate returns.  However,  the qualifications set
         out in paragraph  Fifth above  concerning the calculation of a separate
         return tax shall apply; 

         (b) Each company  having a net operating  loss or other net tax benefit
         will  receive  in  current  cash  payments  the  benefit of its own net
         operating  loss (except as described in paragraph  Second) or other net
         tax  benefits to the extent that the other  companies  can utilize such
         items to  offset  the tax  liability  they  would  otherwise  have on a
         separate return basis.

         III.   EFFECTIVE  DATE:  This  Tax  Agreement  will  be  effective  for
                ---------------
allocation of the current income tax liability of the system for the fiscal year
1997 and all  subsequent  years  until  this Tax  Agreement  shall be amended in
writing by each of the  companies  which is a party  thereto.  

         IV. APPROVAL AND  AMENDMENTS:  Any amendments to this Tax Agreement may
             ------------------------
be made only with the unanimous  written  consent of all the parties  hereto.  A

<PAGE>

copy of this Tax Agreement is being filed as an exhibit to  National's  Form U5S
Annual  Report to the  Securities  and  Exchange  Commission  for the year ended
September 30, 1997.  Any  amendments  to this Tax Agreement  will be filed as an
exhibit  to  National's  Form  U5S for  the  year  when  the  amendment  becomes
effective.  It is  contemplated  that any additional  companies  which hereafter
become  associated  with the  System  shall  have the  option of  joining in and
becoming a party to this Tax Agreement by amendment thereto.

         V. PRIOR AGREEMENTS  SUPERSEDED:  Any prior agreements  relating to the
allocation of income tax liability among the System are superseded.

         IN WITNESS  WHEREOF,  each of the  parties  hereto have caused this Tax
Agreement  to be executed  in its name and on its behalf by one of its  officers
duly authorized, and its corporate seal to be affixed hereto by its Secretary on
this 28th day of January 1998.
