                                  ARTICLE 3
                              POINT OF RECEIPT

3.01  Shipper  shall  deliver or cause to be  delivered  gas for  transportation
hereunder and Transporter shall receive gas quantities up to Shipper's TCQ, plus
any   applicable   fuel  and  line  loss  makeup,   at  the  existing  point  of
interconnection  between  Transporter  and the  pipeline  system of  Transco  in
Rockingham County, North Carolina ("Point of Receipt"). Transporter shall accept
deliveries at the Point of Receipt at a pressure  sufficient to allow the gas to
enter  Transporter's  pipeline system at the varying pressures that may exist in
such system from time-to-time;  provided,  however, that such pressure(s) of the
gas  delivered or caused to be delivered by Shipper shall not exceed the maximum
operating pressure(s) specified by Transporter for the Point of Receipt.

3.02 Shipper shall make any necessary arrangements with Transco so as to be able
to deliver gas to Transporter at the Point of Receipt;  provided,  however, that
such arrangements are compatible with the operating  conditions on Transporter's
pipeline system.


                                   ARTICLE 4
                             POINT(S) OF DELIVERY

Transporter shall deliver to Shipper, or for the account of Shipper,  Equivalent
Quantities  hereunder  at the  existing  points of  interconnection  between the
systems of Transporter  and Shipper and any upstream  points of delivery  within
Shipper's  TCQ  capacity  entitlements.  Transporter  shall  design its pipeline
facilities and use reasonable efforts to deliver gas at the Point(s) of Delivery
at a minimum  pressure of not less than 500 psig.  The  maximum  pressure at the
Point(s)  of  Delivery  shall not  exceed  the  maximum  operating  pressure  of
Transporter's pipeline at such point(s).


                                   ARTICLE 5
                   DETERMINATION OF RECEIPTS AND DELIVERIES

5.01 Receipts and deliveries shall be allocated by  Transporter according to a
predetermined methodology administered by Transporter for the allocation among
shippers  each Day of each dt of gas which is  delivered by  Transporter  at the
Point(s) of Delivery. Under the current allocation methodology,  the quantity of
gas  allocated  each Day to each Shipper at the Point of Receipt shall be deemed
to be, to the maximum extent possible,  the quantities of gas delivered for such
Shipper's  account  at the  Point(s)  of  Delivery  hereunder  adjusted  for any
quantities attributable to fuel and line loss makeup.

5.02 Shipper shall cause  Transco to provide  Transporter  with a  predetermined
daily allocation  methodology in writing,  or electronically (by electronic data
transfer) for measured  quantities  based on scheduled  quantities in advance of
service  each Day and prior to any  intra-day  changes  pursuant to Section 7.02
below.  The daily  allocation  methodology  provided by Transco shall consist of
rankings for allocation among all shippers nominating service such that receipts
are  equivalent to the quantities  delivered by Transporter  plus any quantities
applicable for fuel or line loss makeup.







                                   ARTICLE 6
            DETERMINATION OF ALLOWABLE DAILY DELIVERY VARIATIONS
                           AND OVERRUN PENALTIES

6.01  Allowable  daily  delivery  variations  shall be the quantity  computed as
      follows:

(a) During  each Day of the  period  beginning  May 1 of any Year and  extending
through the next succeeding  September 30, 5 percent of Shipper's TCQ under this
Service Agreement.

(b)  During  each  Day of the  period  beginning  on  October  1 of any Year and
extending  through the next  succeeding  April 30, 3.5 percent of Shipper's  TCQ
under this Service Agreement.

6.02 Any quantity of gas taken by Shipper on any Day from  Transporter in excess
of  Shipper's  TCQ under  this  Service  Agreement  shall,  as  adjusted  by the
allowable daily delivery  variations  above,  be an  unauthorized  daily overrun
unless:

(a) Shipper is utilizing the firm capacity  entitlements of another firm shipper
that is not using that  capacity  entitlement  and  Shipper has  provided  prior
notice to Transporter, or

(b)  Shipper is  utilizing  Excess  Rate  Schedule  CFT  Service  which has been
scheduled by Shipper and allocated by Transporter on such Day.

6.03 In the event of a Force Majeure,  Shipper's revised TCQ pursuant to Article
17 below shall be utilized to determine the allowable  daily delivery  variation
and unauthorized daily overrun quantity and any penalties thereon.  Notice shall
be provided  by  Transporter  to Shipper of such  revised  TCQ by  telephone  or
telecopy.  Such  notice  shall be  confirmed  in writing  as soon as  reasonably
possible.

6.04  In  the  event  on  any  Day  Shipper  takes  unauthorized  daily  overrun
quantities, Shipper shall pay Transporter:

(a) an overrun  charge  equal to the 100 percent  load factor FT rate per dt for
quantities up to, but not exceeding,  the daily allowable delivery variation set
forth in Section 6.01 above, and

(b) an overrun penalty of $25 per dt for each dt of  unauthorized  daily overrun
quantities in excess of the daily  delivery  variation set forth in Section 6.01
above.

6.05 All overrun  penalties  collected by Transporter  during any calendar year,
less an amount equal to the 100 percent load factor FT rate per dt multiplied by
the total volume of overruns, shall be directly refunded to each non-overrunning
firm  transportation  shipper  for the  Month(s)  in which such  penalties  were
incurred based on each such  non-overrunning  shipper's fixed cost  contribution
under its service  agreement with Transporter as a percentage of the total fixed
cost  contributions  of all  non-overrunning  shippers  under  all firm  service
agreements. Such refunds shall be made by January 31 of each calendar year.

6.06 The payment of a penalty for an unauthorized  overrun  quantity shall under
no  circumstances  be  considered  as  giving  Shipper  the  right to take  such
unauthorized  overrun  quantity  nor  shall  such  payment  be  considered  as a
substitute  for any other remedy  available to  Transporter or any other shipper
against the offending shipper for such unauthorized overrun.

                                ARTICLE 7
                        SCHEDULING AND BALANCING

7.01 Shipper shall nominate  service under this Service  Agreement in advance of
each Month or in advance of each Day in accordance with the nomination deadlines
of  Transco.  Transporter,  in its sole  judgement,  may  waive  any  nomination
deadlines,  on  a  non-discriminatory  basis,  if  Transporter  determines  that
operating  conditions  permit.  Such  nominated  quantities  shall be subject to
confirmation  by  Transporter  which  shall  be  based  on  the  best  operating
information available to






Transporter.  Such confirmed  quantity  shall be deemed the scheduled  quantity.
Shipper  and  Transporter  shall  have  scheduling  personnel  available  to  be
contacted seven days a week, twenty-four hours a day.

7.02 During any Day, Shipper may request to reschedule,  on a prospective basis,
quantities  scheduled  pursuant  to  Section  7.01  above,  provided  that  such
quantities are consistent with rescheduled quantities and deadlines on Transco.

7.03 Shipper shall endeavor to balance  receipts and deliveries as reasonably as
practicable  so that the  quantities  delivered  by Transco to  Transporter  are
consistent  with the  actual  quantities  taken by Shipper  at the  Point(s)  of
Delivery.  Shipper shall have the  responsibility  to monitor daily receipts and
deliveries during the Month based on the best information available.

7.04 Transporter shall provide its latest estimated  allocation data on receipts
and deliveries to all parties  requesting such data. These allocated  quantities
will be subject to change and the data is  offered  for  informational  purposes
only, and should not be relied on by Shipper for any purposes whatsoever.

                                 ARTICLE 8
                        SHIPPER'S RESPONSIBILITIES

Shipper recognizes that, as between it and Transporter, Shipper has sole control
over its physical  takes of gas from  Transporter's  system and  therefore has a
duty to refrain from taking delivery of unauthorized overrun quantities. Shipper
further  recognizes that Shipper may cause hardship and economic damage to other
shippers in the event Shipper takes delivery of unauthorized  overrun quantities
for which  Shipper  may be held  accountable  either  through a direct  cause of
action by such other  shippers or as an impleaded or third party  defendant in a
suit by such other  shippers.  In no event shall the payment of a penalty for an
overrun  quantity  pursuant to this Service  Agreement be  considered  as giving
Shipper  the right to take such  unauthorized  overrun  quantity  nor shall such
payment  be  considered  as a  substitute  for all  other  rights  and  remedies
(including  but not limited to  consequential  damages)  available  to any other
shipper against Shipper.

                                  ARTICLE 9
                        TRANSPORTER'S RESPONSIBILITIES

Transporter  recognizes  that it has a duty to use  reasonable  care and prudent
operating  procedures to allow Shipper to schedule for delivery  within its TCQ,
as adjusted pursuant to a Force Majeure situation or Operating  Conditions,  the
gas quantities  available to Shipper up to the amount  verified and confirmed by
Transporter  based on the best operating  information  available to Transporter.
Transporter  also  recognizes  that unless forces beyond  Transporter's  control
(including,  but not limited  to,  Force  Majeure,  or the failure of Shipper or
Shipper's gas supplier to deliver  scheduled gas quantities  into  Transporter's
system) cause interference with Transporter's ability to redeliver,  Transporter
has a duty  to  tender  to  Shipper  for  redelivery  the gas  quantities  which
Transporter  has  verified and  confirmed  as available to Shipper.  Transporter
further  recognizes  that a breach of its duties  herein may cause  hardship and
economic damage to Shipper,  for which Shipper  reserves all rights and remedies
(including but not limited to consequential  damages), and for which Transporter
may be held accountable.

                                 ARTICLE 10
                             RATES AND CHARGES

10.01 For firm  transportation  service provided to Shipper  hereunder,  Shipper
shall pay to Transporter each month the sum of the following charges:

(a)  Reservation  Charge:  Shipper's  TCQ  multiplied  by the  reservation  rate
applicable  to  deliveries in the rate zone in which the gas is delivered and as
set forth on currently effective Sheet No.
1 of Transporter's tariff.







(b)  Commodity  Charge:  The  applicable  commodity  rate set forth on currently
effective Sheet No. 1 multiplied by the quantities of gas (dts) delivered.

(c) Excess CFT Charge:  The  applicable  rate set forth on  currently  effective
Sheet No. 1 multiplied by the excess CFT quantity delivered during that month.

10.02  Transporter shall retain from the quantities of gas received on behalf of
Shipper hereunder any applicable fuel and line loss make-up  associated with the
transportation  service provided  hereunder.  Transporter will evaluate any fuel
retention  percentages  applicable  to Shipper's  service on an annual basis and
will make any  necessary  filings  with the NCUC to reflect any changes at least
thirty (30) days prior to April 1 of each calendar year.

10.03 Transporter shall have the right, from time-to-time,  through filings with
the  governmental  agency  having  jurisdiction  to seek to change  the rates or
allowance for fuel, and to change the other terms and conditions of this Service
Agreement,  without limitation or reservation;  provided,  however, that (a) the
character of firm service, (b) the term, (c) the quantities, (d) the Point(s) of
Receipt and  Delivery,  and (e) the  delivery  pressure  shall not be subject to
change hereunder without mutual agreement of the parties. Shipper shall have the
right to oppose any of the  foregoing and to seek other changes to the terms and
conditions  of this  Service  Agreement  to the extent  that  Shipper is legally
permitted to do so under applicable provision(s) of law.

                                 ARTICLE 11
                               QUALITY OF GAS

11.01  The  parties  hereto   recognize  that  the  natural  gas  delivered  for
transportation   hereunder  will  necessarily  be  commingled  in  Transporter's
pipeline system with gas received from other sources,  and that the specific gas
delivered to Transporter  cannot be  redelivered  for Shipper's  account.  It is
further  agreed that the natural gas delivered to and by  Transporter  hereunder
shall be merchantable natural gas.

11.02  All  gas  delivered  to  Transporter   for  Shipper  and  redelivered  by
Transporter to Shipper shall meet the quality  standards for  transportation  on
the interstate pipeline system of Transco as amended from time-to-time.

                                 ARTICLE 12
                     MEASUREMENT AND MEASURING EQUIPMENT

12.01  The unit of the natural gas deliverable hereunder shall be a Dekatherm of
gas on the measurement basis hereinafter set forth.

12.02 The  quantity  and the  Heating  Value of the  natural  gas  delivered  by
Transporter  to or for the  account  of  Shipper  or  delivered  by  Shipper  to
Transporter for redelivery shall be determined as follows:

(i) The unit of volume  for the  purpose of  measurement  shall be one (1) Cubic
Foot  of  gas at a  temperature  of 60  degrees  Fahrenheit  and at an  absolute
pressure of fourteen and seventy-three  hundredths  (14.73)  pounds per square
inch.

(ii) The unit of weight for the purpose of measurement shall be one (1) pound 
mass of gas.

(iii The average absolute atmospheric pressure shall be assumed to be 14.73 
pounds per square inch.

(iv) The temperature of the gas flowing  through the meters,  when necessary for
computing  gas  quantities,  shall  be  determined  by the  use  of a  recording
thermometer or other temperature measuring device. The arithmetic average of the
temperature  recorded  each  24-hour  day, or so much of the 24 hours as gas has
been flowing, shall be used in computing gas quantities or






instantaneous temperature measurements may be applied to metering instruments to
provide the quantity computation.

(v) The specific  gravity of the gas flowing through the meters,  when necessary
for computing gas quantities, shall be, unless otherwise agreed upon, determined
by  the  use  of  a  recording  gravitometer  or  an  online  process  type  gas
chromatograph.  The arithmetic average of the 24- hour record, or so much of the
24 hours as gas has been flowing, or continuous  instantaneous  specific gravity
measurement  may be applied to  metering  instruments  to  provide  the  quality
computation.

(vi) The deviation of the gas from Ideal Gas Laws shall be calculated  following
the  recommendations  of the ANSI/API 2530 "Orifice  Metering of Natural Gas and
Other Related  Hydrocarbon  Fluids"  (A.G.A.  Report No. 3) including the A.G.A.
Manual for Determination of  Supercompressibility  Factors of natural Gas or the
A.G.A.  Transmission  Measurement  Committee Report No. 8  "Compressibility  and
Supercompressibility  for  Natural  Gas and  Other  Hydrocarbon  Gases."  If the
composition  of the gas is such as to render the above  procedure  inapplicable,
other methods for determination of the deviation  factors,  mutually agreed upon
by Shipper and Transporter, shall be used.

(vii) The Heating  Value shall be determined by either (1) the use of a suitably
located  and  acceptable  make  gas  chromatograph  or  (2)  calculation  from a
fractional analysis, or (3) methods outlined in A.G.A. Gas Measurement Committee
Report  No.  5,  latest  edition,  or (4)  other  methods  mutually  acceptable.
Dekatherms  delivered  shall be  determined  by either (1)  multiplying  the Mcf
delivered by a fraction the numerator of which is the Btu per cubic foot and the
denominator of which is 1,000 or (2)  multiplying the pounds mass delivered by a
fraction the numerator of which is the Btu per pound mass and the denominator of
which is 1,000,000.

12.03 Unless otherwise agreed to,  Transporter will install,  maintain,  own and
operate,  at its own expense, at or near each Point of Receipt and each Point of
Delivery,  measuring  stations  properly  equipped with standard orifice meters,
flange  connections,  orifice plates and other necessary  measuring equipment or
other  standard  type meter  suitable  for the purpose by which the  quantity of
natural gas shall be measured and  determined.  The Heating Value of natural gas
received  or  delivered  shall be measured  and  determined  as provided  above.
Orifice  meters where used shall be installed  and operated in  accordance  with
ANSI/API "Orifice Metering of Natural Gas and Other Related Hydrocarbon Fluids"
latest revision, and shall include the use of straightening vanes.

12.04 Shipper acting jointly with Transporter may install, maintain and operate,
at its own expense,  such check  measuring  equipment as desired,  provided that
such  equipment  shall be so installed as not to interfere with the operation of
Transporter's measuring equipment.

12.05 Each party  shall have the right to be present at the time of  installing,
reading, cleaning, changing,  repairing,  inspecting,  testing,  calibrating, or
adjusting done in connection  with measuring  equipment  involved in billing and
used in measuring or checking the  measurement of receipts and  deliveries.  The
records from such measuring  equipment shall remain the property of their owner,
but upon request, each will submit to the other its records and charts, together
with calculations  therefrom for inspection and verification,  subject to return
within ten (10) days after receipt thereof.

12.06 All  installations  of  measurement  equipment  applying  to or  affecting
receipts  and  deliveries  shall be made in such manner as to permit an accurate
determination of the quantity of natural gas delivered and ready verification of
the accuracy of measurement.  Care shall be exercised by Transporter and Shipper
in the installation,  maintenance and operation of pressure regulating equipment
so as to prevent any  inaccuracy  in the  determination  of the  quantity of gas
received or delivered hereunder.

12.07  In the event a meter is out of service, or registering inaccurately, the
quantity of natural gas received or delivered shall be determined,







(i)  By using the registration of any check meter or meters if installed and 
accurately registering, or, in the absence of (i),

(ii) By  correcting  the error or the  percentage of error if  ascertainable  by
calibration,  test, or mathematical  calculation,  or in the absence of both (i)
and (ii), then

(iii) By estimating the quantity of receipts or deliveries  during periods under
similar conditions when the meter was registering accurately.

12.08 The accuracy of Transporter's measurement  equipment shall be verified by
Transporter  at  reasonable  intervals,  and, if  requested,  in the presence of
representatives of Shipper, but Transporter shall not be required as a matter of
routine to verify the accuracy of such  equipment more  frequently  than once in
any thirty (30) day period.

12.09  If,  upon  test,  any  measurement  equipment,  including  recording  gas
chromatograph,  is found to be in error not more than two percent (2%), previous
recording of such equipment shall be considered  accurate in computing  receipts
and  deliveries;  but  such  equipment  shall  be  adjusted  at once  to  record
correctly.  If,  upon  test,  any  measurement  equipment  shall  be found to be
inaccurate by an amount exceeding two percent (2%) at a recording  corresponding
to the average hourly rate of flow for the period since the last preceding test,
then any previous  recordings of such equipment shall be corrected to zero error
for any period which is definitely  known,  but, in case the period is not known
definitely or agreed upon, such correction  shall be for a period extending over
one-half of the time elapsed  since the date of the last test,  not  exceeding a
correction period of 16 days.

12.10  Transporter  and  Shipper  shall  preserve  all  original  or  equivalent
electronic test data,  charts, or other similar records for a period required by
the applicable rules of regulatory agencies having jurisdiction.

                                 ARTICLE 13
                             TERM OF AGREEMENT

13.01 This Agreement shall be effective as of the date hereof and shall continue
in effect until the  expiration  of the  twentieth  (20th)  Contract  Year,  and
year-to-year  thereafter,  subject to  termination by either party at the end of
the Contract Year or any year  thereafter  upon two years advance written notice
to the other party.

13.02 Firm transportation service hereunder shall commence at the Effective Time

in the Agreement and Plan of Merger, as amended.

                                 ARTICLE 14
                            BILLING AND PAYMENT

14.01 Transporter shall render its bill on or before the first Day of each Month
for the  Reservation  Charges  due for  service  rendered  hereunder  during the
preceding  calendar Month. On or before the 10th day of each Month,  Transporter
shall render its bill for any remaining charges for gas services rendered during
the preceding  calendar  Month.  Such bill shall include any Commodity  Charges,
Excess CFT Charges,  any  adjustments  to the charges billed on the first day of
the Month, and any penalties for unauthorized  overruns  applicable to the Month
for which the bill is rendered.

14.02 Transporter and Shipper shall each, upon request of the other,  deliver to
the  other  for  examination  such  pertinent  records  and  charts  as shall be
necessary to verify the accuracy of any statement, chart, or computation made by
either of them under or pursuant to any of the provisions hereof.

14.03  Shipper,   except  as  otherwise  hereinafter  provided,   shall  pay  to
Transporter  by wire transfer of  immediately  available  funds on or before the
10th day of each Month for the Reservation  Charges due for service  rendered by
Transporter hereunder during the preceding month and billed by






Transporter  in the statement for such month,  and on or before the 20th day for
each Month for any remaining  charges for services which are due  hereunder.  If
the normal  payment due date is a Saturday,  Sunday or holiday,  this payment is
due the following business Day.

14.04  Should  Shipper  fail to pay all of the  amount  of any bill for  service
hereunder when such amount is due, interest on the unpaid portion of such amount
shall  accrue  at the rate  equal to the prime  rate of  CitiBank,  N.A.  or its
successor,  calculated  from the due date  until  the date of  payment.  If such
failure to pay continues for thirty (30) days after payment is due, Transporter,
in  addition to any other  remedy it may have  hereunder,  may  suspend  further
transportation  of natural gas  hereunder  until such amount is paid;  provided,
however, that if Shipper in good faith shall dispute the amount of any such bill
or any part hereof,  and shall pay to Transporter  such amount as it concedes to
be correct,  and at any time thereafter within thirty (30) days of a demand made
by  Transporter,  shall furnish good and  sufficient  surety bond,  guaranteeing
payment to Transporter of the amount  ultimately found to be due under such bill
after a final  determination,  which may be reached either by agreement  between
the parties,  arbitration or judgment for a court or by any regulatory authority
having  jurisdiction,  then Transporter shall not be entitled to suspend further
delivery of natural gas unless and until  default be made in the  conditions  of
such bond.

14.05 If within  twelve (12)  months of the date of  payment,  it shall be found
that Shipper has been  overcharged or undercharged in any form whatsoever  under
the  provisions  hereof,  and  Shipper  shall  have  actually  paid the  bill(s)
containing such  overcharge or  undercharge,  then within thirty (30) days after
the final determination thereof, Transporter shall refund the amount of any such
overcharge  with interest  thereon at the prime rate of the CitiBank N.A. or its
successor  from the time such  overcharge  was paid to the date of  refund,  and
Shipper shall pay the amount of any such undercharge but without interest.

14.06 In the event an error is  discovered in the amount billed in any statement
rendered by Transporter, such error shall be adjusted within thirty (30) days of
the  determination  thereof,  provided that claim  therefor shall have been made
within  sixty (60) days from the date of  discovery  of such  error,  but in any
event, within twelve (12) months from the date of payment.

14.07 If rendition  of a bill to Shipper by  Transporter  is delayed  beyond the
date specified herein,  then Shipper shall pay such bill by wire transfer within
ten (10) days after rendition thereof.

                                 ARTICLE 15
                             ASSUMPTION OF RISK

15.01 As between the parties  hereto,  Shipper  shall be deemed to be in control
and possession of the gas to be transported  hereunder  until it shall have been
delivered to Transporter at the Point of Receipt; and Shipper shall be deemed to
be in  control  and  possession  of the gas to be  transported  hereunder  after
delivery for Shipper's  account at the Point of Delivery.  Transporter  shall be
deemed to be in control and possession of such gas after the delivery thereof to
Transporter at the Point of Receipt and prior to delivery  thereof for Shipper's
account at the Point of Delivery.

15.02  Transporter  shall have no  responsibility  with respect to any gas to be
transported  hereunder  or on account of anything  which may be done,  happen or
arise with respect  thereto  until it is delivered  into its  facilities  at the
Point of Receipt and after it is received for Shipper's  account at the Point of
Delivery.  Shipper shall have no  responsibility  with respect to such gas or on
account of  anything  which may be done,  happen or arise with  respect  thereto
after causing the delivery  thereof to  Transporter  at the Point of Receipt and
prior to delivery thereof for Shipper's account at the Point of Delivery.

                                 ARTICLE 16
                                 WARRANTIES

Shipper  warrants for itself,  its successors  and assigns,  that it will at the
time of delivery to Transporter for  transportation  have good and  merchantable
title to or the legal right to tender all gas delivered hereunder






free and clear of all liens,  encumbrances  and claims.  Shipper shall indemnify
Transporter  and save it  harmless  from all suits,  actions,  debts,  accounts,
damages, costs, losses and expenses arising from or out of adverse claims of any
or all persons to said gas, including claims for any royalties,  taxes,  license
fees or charges applicable to such gas or to the delivery thereof to Transporter
for transportation under this Service Agreement.

                                   ARTICLE 17
                                 FORCE MAJEURE

17.01 In the event of either party being rendered unable,  wholly or in part, by
Force Majeure or Operating  Conditions to carry out its  obligations  other than
(i)  the  obligation  of  Shipper  to pay the  monthly  Reservation  Charge  due
Transporter (except as provided in 17.03 below), and (ii) the obligation to make
payment of amounts  accrued  and due at the time  thereof,  it is agreed that on
such  party's  giving  notice  and full  particulars  of such  Force  Majeure or
Operating  Conditions  in writing or by  telecopy  to the other  party  within a
reasonable  time after the  occurrence of the cause relied on, the obligation of
both  parties,  so far as they are  affected by such Force  Majeure or Operating
Conditions,  shall be  suspended  during the  continuance  of any  inability  so
caused,  but for no longer  period,  and such cause  shall so far as possible be
remedied with all reasonable dispatch.  Neither party shall be liable in damages
to the  other  for any  act,  omission  or  circumstance  occasioned  by,  or in
consequence of, Force Majeure or Operating Conditions, as herein defined in this
Service Agreement.

17.02 If, due to Force Majeure or Operating Conditions, Transporter is unable to
receive, transport or redeliver gas tendered by Shipper for transportation or if
Shipper  is  unable  to  deliver  gas to  Transporter,  then  Transporter,  upon
providing as much notice as possible under all of the circumstances, shall order
reduction of Shipper's TCQ to the extent  necessary  depending upon the type and
location  of the  occurrence,  in  accordance  with  the  following  procedures:
Transporter  shall  order  allocation,  to the  extent  necessary,  of  affected
transportation  service to all shippers  proportionate  to each  shipper's  TCQ.
Where  Transporter's  ability to render  service  is  impaired  in a  particular
segment of Transporter's  system, then such allocation shall be effected only in
that segment of Transporter's system in which service has been impaired.

17.03 Such causes or  contingencies  affecting the  performance by either party,
however,  shall not relieve it of liability  unless such party shall give notice
and full  particulars  of such cause or contingency in writing or by telecopy to
the other party within a reasonable  time after the occurrence  relied upon, nor
shall such causes or  contingencies  affecting the  performance  by either party
relieve it of  liability  in the event of its  failure to use due  diligence  to
remedy the situation and remove the cause with all reasonable dispatch, provided
that the resolution of strikes, lockouts or other labor disputes shall be within
the  sole  discretion  of  the  parties   involved   therein.   Such  causes  or
contingencies  affecting  the  performance  by either  party  shall not  relieve
Shipper from its  obligations  to make  payments of monthly  Reservation  Charge
except to the extent of Transporter's negligence or willful misconduct.

                              MISCELLANEOUS

19.01  Transporter  grants the right to Shipper to direct  tie-ins  between  its
distribution  system and  Transporter's  intrastate  pipeline for the purpose of
serving its franchise area subject to the negotiation of mutual  agreeable terms
and conditions (including reimbursement  arrangements and/or incremental charges
and the construction, operation and maintenance specifications for such tie-ins)
which will be set forth in an  Interconnect  and  Reimbursement  Agreement to be
negotiated and executed by Shipper and Transporter.

19.02 This  Agreement  reflects  the entire  agreement  between the parties with
respect to the subject  matter hereof and  supersedes  all prior  agreements and
understandings,  oral and written, among the parties with respect to the subject
matter hereof.  This Agreement can be amended,  restated or supplemented only by
the written agreement of Transporter and Shipper.

19.03 No  waiver  by  either  party of any  default  by the  other  party in the
performance of any provision, condition or requirement herein shall be deemed to
be a waiver of, or in any manner  release the other party from,  performance  of
any other provision,  condition or requirement  herein, nor shall such waiver be
deemed to be a waiver  of, or in any manner a release  of, the other  party from
future performance of the same provision, condition or requirement. Any delay or
omission of either  party to exercise any right  hereunder  shall not impair the
exercise of any such right,  or any like right,  accruing to it  thereafter.  No
waiver of a right  created by this  Agreement  by one party shall  constitute  a
waiver of such right by the other party  except as may  otherwise be required by
law with  respect to persons  not  parties  hereto.  The failure of one party to
perform  its  obligations  hereunder  shall not release the other party from the
performance of such obligations.

19.04 This  Agreement  may be assigned by Shipper  without the prior  consent of
Transporter   provided  that  Shipper  remains   responsible  for  any  and  all
obligations under this Agreement.

19.05 This Agreement and the obligations of the parties hereunder are subject to
all  applicable  laws,  rules,   orders  and  regulations  of  any  governmental
authorities having jurisdiction, and to the extent of






conflict,  such laws, rules, orders and regulations of governmental  authorities
having jurisdiction shall control.

19.06 Any provision of this Agreement that is prohibited or unenforceable  shall
be ineffective to the extent of that  prohibition  or  unenforceability  without
invalidating  the  remaining  provisions  hereof or  affecting  the  validity or
enforceability of that provision in any other jurisdiction.

19.07 This  Agreement  may be executed in  counterparts,  each of which shall be
deemed an original,  but all of which together shall constitute one and the same
instrument.








19.08 THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE LAWS OF THE STATE OF NORTH CAROLINA.  EXCLUDING, HOWEVER,
ANY CONFLICT OF LAWS RULES OR PRINCIPLES WHICH MIGHT REFER THE
CONSTRUCTION OR OPERATION OF THE TERMS OF THIS AGREEMENT TO THE
LAWS OF ANOTHER STATE.

         IN WITNESS  WHEREOF,  the  parties  have caused  this  Agreement  to be
executed  by their duly  authorized  representatives  as of the date first above
written.
