                    save to the extent that Gascor would not have incurred such
                    a liability had it claimed exemption from liability under
                    section 32 of the Act.

(n)       Apportionment of Receivables

          (1)       When a Gascor Customer whose Meter is capable of recording
                    metering data on a daily basis and storing data in a data
                    logger ceases to be a Gascor Customer on a Contestability
                    Date and becomes a Customer of the Agent on that
                    Contestability Date, the Agent must within 60 days after
                    that Contestability Date, read that customer's Meter and
                    issue a bill to that customer in respect of the unbilled Gas
                    supplied by the Agent to that customer on behalf of Gascor
                    prior to the relevant Contestability Date.

          (2)       When a Gascor Customer whose Meter does not record metering
                    data on a daily basis and cannot store data in a data logger
                    ceases to be a Gascor Customer on a Contestability Date and
                    becomes a Customer of the Agent on that Contestability Date,
                    the Agent must determine the quantity of Gas supplied by the
                    Agent to that Gascor Customer on behalf of Gascor prior to
                    that Contestability Date ("PRIOR GAS") by apportioning the
                    quantity of Gas billed after that Contestability Date which
                    relates to a period which includes that Contestability Date
                    between Gascor and the Agent in proportion to the number of
                    days in that period prior to and including the
                    Contestability Date and the number of days in that period
                    after the Contestability Date respectively.

          (3)       In relation to the apportionment under Clause 3.2(n)(ii),
                    only that proportion of the Receivables which relates to
                    Prior Gas is required to be deposited by the Agent in the
                    Designated Accounts pursuant to Clause 3.2(g).

          (4)       When a Gascor Customer ceases to be a Gascor Customer on a
                    Contestability Date and:

                    (A)       becomes a Customer of a person other than the
                              Agent on that Contestability Date; or

                    (B)       having become a Customer of the Agent on that
                              Contestability Date ceases to be a Customer of the
                              Agent before the quantity of Gas supplied by the
                              Agent to that Customer can be determined under
                              Clause 3.2(n)(i) or (ii),

                    the Parties must agree the basis on which the Receivables
                    relating to unbilled Gas supplied to the Gascor Customer on
                    behalf of Gascor prior to the Contestability Date shall be
                    determined. If the Parties cannot agree on such basis within
                    30 days of the Contestability Date, either Party may refer
                    the matter to Gascor's Accountants for determination, whose
                    determination shall be final and binding on the Parties. Any

                    such determination must be consistent with the relevant
                    provisions of the MSO Rules, the Distribution System Code
                    and the Customer Service Code.

                    when a Customer in the Agency Area ceases to be a Gascor
                    Customer, the Agent will cease to sell Gas to that Customer
                    as agent for Gascor and that, to the extent that the Agent
                    continues to sell Gas to that Customer, it will do so as
                    principal.

          (2)       Subject to Clause 3.3(d)(2), Gascor must, if it is able to
                    do so, assign to the Agent, with effect from each
                    Contestability Date, all Gascor's rights, title and interest
                    in and to any Sales Contract with a Customer who ceases to
                    be a Gascor Customer on that Contestability Date but
                    continues to be supplied Gas by the Agent, save for any
                    Receivables owed by that Customer as at that Contestability
                    Date (which Receivables will remain the property of Gascor).

          (3)       If the consent of the Customer is required for an assignment
                    under Clause 3.3(c)(2), then the Agent must use its best
                    endeavours to obtain that consent.

          (4)       An assignment under Clause 3.3(c)(2) must be made by
                    assignment in the form of the deed of assignment set out in
                    Schedule 4 or such other form as Gascor may approve.

          (5)       If a Sales Contract referred to in Clause 3.3(c)(2) cannot
                    be assigned to the Agent (whether because the consent of the
                    relevant Customer cannot be obtained or for any other
                    reason) or cannot be terminated by Gascor or is to remain in
                    effect following an election by Gascor not to exercise its
                    right of termination:

                    (A)       the Agent must:

                              (i)       to the extent it lawfully can, perform
                                        all the obligations of Gascor under the
                                        Sales Contract; and

                              without limitation, because the Agent has

          4.3 and 4.5(b).

(c)       Gascor shall not be required to purchase Gas from any person (other
          than a purchase from a Seller under the Principal Contract) in order
          to satisfy its obligations to the Agent under this Agreement.

4.2       INITIAL NOMINATIONS

(a)       (1)       Subject to Clause 7.3 of the Master Agreement, on or
                    before 15 December in each Contract Year the Agent must
                    provide Gascor with its best estimates, as a Reasonable and
                    Prudent Operator, of the requirements of Gascor Customers in
                    the Agency Area for Contract Gas for the following Contract
                    Year (expressed, in quantities for each Gas Month).

          (2)       Subject to Clause 7.3 of the Master Agreement, on or before
                    the penultimate Working Day of each Gas Month during the
                    Contract Term, the Agent must provide Gascor with its
                    updated best estimates, as a Reasonable and Prudent
                    Operator, of the requirements for Contract Gas of Gascor
                    Customers in the Agency Area for each of the following three
                    Gas Months (expressed in quantities for each Day).

(b)       Subject to Clause 7.3 of the Master Agreement, no later than 11 days
          (or, if that day is not a Working Day, then the immediately preceding
          Working Day) before the commencement of each Gas Month during the
          Contract Term, the Agent must nominate the total quantity of Contract
          Gas which the Agent requires under this Agreement for the following
          Gas Month and for each Day of that Gas Month. The total quantity
          nominated for a Day under this Clause 4.2(b), or deemed to have been
          nominated for a Day under Clause 4.2(d), will be the "INITIAL
          NOMINATION" for that Day.

(c)       The Agent must ensure that each Initial Nomination, and any variation
          pursuant to Clause 4.3, will be made in good faith and when given will
          be the Agent's best estimate as a Reasonable and Prudent Operator of
          its requirements for Contract Gas to be delivered under this Agreement
          for the relevant Gas Month or Day (as the case may be).

(d)       If the Agent fails to submit a nomination under Clause 4.2(b) for a
          Gas Month and for each Day of that Gas Month, the Agent will be deemed
          to have nominated:

          (1)       in respect of the Gas Month, a quantity of Contract Gas
                    equal to the quantity of Contract Gas (if any) which the
                    Agent estimated under Clause 4.2(a)(1) would be required for
                    that Gas Month; and

          (2)       in respect of each Day of the Gas Month, a quantity of
                    Contract Gas calculated by dividing the quantity of Contract
                    Gas (if any) which the Agent estimated under Clause


                                       25
<PAGE>


                    4.2(a)(1) would be required for the Gas Month by the number
                    of Days in the Gas Month.

(e)       If the Agent fails to provide Gascor with its best estimates for a
          Contract Year in accordance with Clause 4.2(a)(1), the Agent will be
          deemed to have estimated that the requirements of Gascor Customers in
          the Agency Area for Contract Gas in that Contract Year will be equal
          to zero.

4.3       VARIATION OF INITIAL NOMINATIONS

                              for the following Day, which may differ from and
                              vary the Initial Nomination.

                    (B)       If the Agent fails to notify Gascor in accordance
                              with Clause 4.3(a)(1)(A), then the Agent's
                              requirements for Contract Gas to be delivered for
                              the following Day will be taken to be the same as
                              those nominated under Clause 4.2(b) or deemed to
                              have been nominated under Clause 4.2(d).

                              its Sub-Sales Agreement;

                    (D)       any other Retailer or RCo in accordance with
                              Clause 3.3(a)(I) of its Sub-sales Agreement; or

                    with Clause 5.3(a) of the Principal Contract, which reflect
                    the aggregate quantity of gas for the following Day
                    nominated by the Agent under this Agreement and its
                    Sub-sales Agreement and all other Retailers under their

(d)       Subject to Clause 7.3 of the Master Agreement, if because of matters
          connected with the safety or integrity of the gas transportation

          an amended nomination to Gascor (irrespective of whether the Agent has
          previously given amended nominations on that Day pursuant to Clause
          4.3(b)). Any amended nomination given pursuant to this Clause 4.3(d)

          that Day under Clause 5.3(b) or 5.3(c) of the Principal Contract.

4.4       MEANING OF "DAILY NOMINATION"

(a)       The "Daily Nomination" for a Day means:

          (1)       the Initial Nomination for that Day unless a notice of

                              distribution pipelines operated by Stratus which
                              the Agent must estimate in accordance with the
                              Estimation Procedures;

                    MW        is the aggregate quantity of Gas (expressed in GJ)

                              at Class B Supply Points in the Agency Area on the
                              distribution pipelines operated by Westar which
                              the Agent must estimate in accordance with the
                              Estimation Procedures.

(b)       To the extent that VENCorp becomes able to determine the aggregate
          quantity of Gas supplied by the Agent in a Market Month to Contestable
          Customers in addition to Contestable Tariff D Customers and Second
          Tier Contestable Customers, then the Parties agree that VENCorp will
          be instructed to make such determinations.

(c)       The procedures for determining any quantity of Gas which the Agent is
          required to estimate in any Month for the purposes of Clause 6.4(a)
          (the "ESTIMATION Procedures") are, as at the date of this Agreement,
          those set out in Schedule 10.

(d)       At any time during the Contract Term either Party may notify the other
          Party that it seeks a review of the Estimation Procedures if it
          considers that the Estimation Procedures are not producing estimates
          which are fair and reasonable.

(e)       If a notice is given pursuant to Clause 6.4(d), the Parties must meet
          within [THIS PARAGRAPH CONTAINS CONFIDENTIAL INFORMATION WHICH HAS
          BEEN OMITTED, BUT FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
          COMMISSION.] days of such notice being given to seek to agree
          necessary amendments to the Estimation Procedures.

(f)       If the Parties are unable to agree amendments to the Estimation
          Procedures within a period of [THIS PARAGRAPH CONTAINS CONFIDENTIAL
          INFORMATION WHICH HAS BEEN OMITTED, BUT FILED SEPARATELY WITH THE
          SECURITIES AND EXCHANGE COMMISSION.] days of a notice being given
          under Clause 6.4(d), either Party may refer the matter to the Agent's
          auditors who shall be required (at the Agent's cost) to recommend
          amendments to the Estimation Procedures.

(g)       In determining any amendments to the Estimation Procedures, the
          Agent's auditors (and any Expert under Clause 6.4(h) must approve only
          those amendments which will ensure that the Estimation Procedures will


                                       36
<PAGE>


          operate in a fair and reasonable manner and in accordance with
          statutory accounting procedures.

(h)       If Gascor reasonably considers that any amendments to the Estimation
          Procedures as recommended by the Agent's auditors do not comply with
          Clause 6.4(g), Gascor may refer the matter to an Expert for
          determination in accordance with Clause 13 within [THIS PARAGRAPH
          CONTAINS CONFIDENTIAL INFORMATION WHICH HAS BEEN OMITTED, BUT FILED
          SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION.] days of
          receiving notice of the amendments recommended by the Agent's
          auditors.

(i)       The Estimation Procedures will be deemed to be amended to those agreed
          pursuant to Clause 6.4(e) or determined pursuant to Clause 6.4(f) or
          Clause 6.4(h) with effect from the date of such agreement or
          determination.

(j)       If:

          (1)       VENCorp cannot differentiate between Gas supplied to Gascor
                    Customers and Gas supplied to other Customers outside the
                    Agency Area; and

          (2)       the quantity of Gas estimated to be supplied to other
                    Customers outside the Agency Area is more than [THIS
                    PARAGRAPH CONTAINS CONFIDENTIAL INFORMATION WHICH HAS BEEN
                    OMITTED, BUT FILED SEPARATELY WITH THE SECURITIES AND
                    EXCHANGE COMMISSION.]% of the quantity of Gas supplied to
                    Gascor Customers in any period,

          then the Parties must endeavour to use, as far as practicable,
          metering data provided by VENCorp in order to estimate the quantity of
          Gas supplied to Gascor Customers but, if that data is not available,
          the Parties shall use the Estimation Procedures as modified to the
          extent required.

(k)       The Agent will enter into an agreement with VENCorp relating to the
          information to be provided by VENCorp as contemplated by this
          Agreement.

(l)       The Agent must provide Gascor with a copy of the agreement referred to
          in Clause 6.4(k) and, when reasonably requested by Gascor, any
          information provided by VENCorp to the Agent under that agreement.

6.5       REDETERMINATION OF GAS DELIVERED

(a)       If Qa in respect of a Gas Month is recalculated by the Agent pursuant
          to Clause 7.2(c) of the Master Agreement, the next Monthly Claim Form
          to be given by the Agent under Clause 6.8(d) must contain:

          (1)       a detailed reconciliation of (on the one hand) the amount of
                    the Commission paid by Gascor to the Agent for Contract Gas
                    for that Month in accordance with the Monthly Claim Form for
                    that Month against (on the other hand) the amount of the
                    Commission which Gascor should have paid to the Agent for


                                       37
<PAGE>

                    Contract Gas for that Month on the basis of Qa as
                    recalculated pursuant to Clause 7.2(c) of the Master
                    Agreement; and

          (2)       the amount payable by one Party to the other Party following
                    the reconciliation referred to in Clause 6.5(a)(l) so as to
                    ensure that the amount of the Commission paid by Gascor to
                    the Agent for Contract Gas in respect of that Month reflects
                    the quantity of Contract Gas delivered during that Month
                    under this Agreement.

(b)       If after the Agent has submitted a First Interim Statement, Second
          Interim Statement or Monthly Claim Form in respect of a Month pursuant
          to Clause 6.8(b), (c) or (d), either Party considers that Qa in
          respect of that Month was not properly measured or calculated in a
          material respect such that the putative Qa differs from the original
          Qa by more than [THIS PARAGRAPH CONTAINS CONFIDENTIAL INFORMATION
          WHICH HAS BEEN OMITTED, BUT FILED SEPARATELY WITH THE SECURITIES AND
          EXCHANGE COMMISSION.]% of the original Qa, whether as a result of a
          measurement error or because more accurate data has subsequently
          become available, and that a revised Qa should be substituted, the
          Agent must, upon becoming aware of the material discrepancy or being
          notified of the material discrepancy by Gascor, redetermine Qa for
          that Month and must then give Gascor a statement specifying the
          substituted QA, details of the improper measurement or calculation or
          new data and the consequential recalculation of Qb for the same Month.

(c)       If Qa in respect of a Month is recalculated by the Agent pursuant to
          Clause 6.5(b), the next Monthly Claim Form to be given by the Agent
          under Clause 6.8(d) must contain:

          (1)       a detailed reconciliation of (on the one hand) the amount of
                    the Commission paid by Gascor to the Agent for Contract Gas
                    for that Month in accordance with the Monthly Claim Form for
                    that Month against (on the other hand) the amount of the
                    Commission which Gascor should have paid to the Agent for
                    Contract Gas for that Month on the basis of Qa as
                    recalculated pursuant to Clause 6.5(b); and

          (2)       the amount payable by one Party to the other Party following
                    the reconciliation referred to in Clause 6.5(c)(l) so as to
                    ensure that the amount of the Commission paid by Gascor to
                    the Agent for Contract Gas in respect of that Month reflects
                    the quantity of Contract Gas delivered during that Month
                    under this Agreement.

(d)       If Qa is recalculated or redetermined by the Agent in accordance with
          Clause 6.5(b), the recalculated or redetermined quantity must be taken
          into account in the next Monthly Statement (as defined in the Agent's
          Sub-sales Agreement) to the extent that it has the effect of
          increasing or reducing Qb.

          amount set out in a Monthly Statement or an Annual Statement after 30
          June in the year following the year to which the Annual Statement
          relates, provided that if an amount due for payment as set out in a
          statement rendered to Gascor under Clause 18.3(a) or Clause 18.3(b) of
          the Principal Contract is disputed by a Seller or Gascor and the
          amount set out in that statement is found to be incorrect, each
          Statement rendered under this Agreement which is affected by that
          error shall be revised accordingly.

6.11      INTEREST ON LATE PAYMENT

(a)       If a Party does not dispute an amount payable by it under a Statement
          and the amount payable under the Statement is not paid by the due
          date, or if any disputed amount is withheld by Gascor but later
          determined or agreed to have been payable, then interest must be paid
          by the relevant Party at the Default Rate on the said amount from (and
          including) the original due date until (but excluding) the date paid.

(b)       If a Party does not pay any amount due to the other Party under this
          Agreement (other than an amount specified in a Monthly Statement as
          payable by Gascor) by the due date, then interest must be paid by the
          Party which owes the amount at the Default Rate on the said amount
          from (and including) the original due date until (but excluding) the
          date paid.

(c)       If any disputed amount has been paid by a Party but is later
          determined or agreed, in whole or in part, not to have been payable,
          then interest must be paid by the Party which received that payment at
          the Default Rate on the amount determined or agreed not to be payable
          from (and including) the original date of payment until (but
          excluding) the date of repayment.

          compounded quarterly on the last day of each Quarter.

6.12      INACCURACY

If after a payment has been made pursuant to a Statement or this Agreement which
was undisputed at the time of payment it is determined that the amount paid did
not accurately reflect the payment which should have been made in accordance
with this Agreement, the necessary adjustment will be made on the next Statement
after such determination and interest at the Default Rate less [THIS PARAGRAPH
CONTAINS CONFIDENTIAL INFORMATION WHICH HAS BEEN OMITTED, BUT FILED SEPARATELY
WITH THE SECURITIES AND EXCHANGE COMMISSION.] per annum will be payable on the
amount of the adjustment, from (and including) the date when such amount was
paid or should have been paid, as the case may be, to (but excluding) the date
of payment of the adjustment.

13.       EXPERT
--------------------------------------------------------------------------------

13.1      APPLICATION OF THIS CLAUSE

Wherever in this Agreement any person is to be appointed as an expert ("EXPERT")
or any matter is to be referred to an Expert, and whenever the Parties agree
that a point of difference between them is to be resolved by an Expert, this
Clause 13 will apply and there will be a single proceeding before the Expert for
the purposes of this Agreement. Gascor and the Agent will be bound by a
determination of an Expert in accordance with this Agreement, save in the event
of fraud or manifest error.

13.2      APPOINTMENT

The procedure for the appointment of an Expert is as follows:

(a)       The Party wishing the appointment to be made must give notice to that
          effect to the other Party, giving details of the matter which is
          proposed to be resolved by the Expert and designating its
          representative in negotiations, being a senior officer of the Party
          with authority to settle the matter. The other Party must within 5
          Working Days give notice designating its representative in
          negotiations, with similar authority.

(b)       Within 15 Working Days of the notice proposing the appointment of an
          Expert, the designated representatives of the Parties must meet to
          seek to resolve the matter.

(c)       If the matter to be referred to the Expert is not resolved by the
          representatives within a period of 10 Working Days of their first
          meeting or 25 Working Days from the date of the notice first referred
          to in Clause 13.2(a), the Parties must meet to agree upon a single
          Expert to whom the matter in dispute will be referred for
          determination.

(d)       If, within 20 Working Days of the first date on which the Parties were
          required to meet pursuant to Clause 13.2(c), the Parties fail to agree
          upon the appointment of a single Expert, any Party to the
          determination may request the President of the Institute of Chartered
          Accountants in Australia to appoint an Expert. In order for the
          request to be valid, the Party giving the request must, at the same
          time as the request is made, give a copy of the request to the other
          Party. Provided each Party is consulted prior to any appointment of an
          Expert, that appointment will be final and binding on the Parties.

13.3      QUALIFICATION

A person may not be appointed, or remain, an Expert if at the time of the
appointment or at any time before that person gives his or her determination
under such appointment, has, has had or may have some interest or duty (either
as an employee or adviser or otherwise) which conflicts or may conflict with his
or her function under such appointment.

13.4      POWERS AND DUTIES

(a)       The Parties may make submissions to the Expert in relation to any
          matter before the Expert for determination. The Expert must, promptly
          after his or her appointment, fix a reasonable time and place (being
          Melbourne unless the Parties agree otherwise) for receiving
          submissions or information from the Parties or from any other persons
          that he or she may think fit. The Expert may make such further
          enquiries and require such other evidence as the Expert may consider
          necessary for determining the matter before him or her and must, in
          accordance with this Agreement, determine the matter with all due
          diligence and speed.

(b)       The Expert will be deemed not to be an arbitrator, but shall render
          his or her decision as an expert and his or her decision will be final
          and binding on the Parties in the absence of fraud or manifest error.
          The Commercial Arbitration Act 1984 and the law relating to
          arbitrators will not apply to the Expert or his or her determination
          or the procedure by which the Expert reaches his or her determination.

(c)       Each Party to the determination will bear the costs and expenses of

          otherwise specifically provided in this Agreement, the cost and
          expenses of the Expert will be apportioned between the Parties in such
          proportions as the Expert, in the circumstances, considers proper.

          Expert's determination must be kept confidential by the Parties to the
          determination during the term of this Agreement and for five years
          after the termination of this Agreement and shall not be disclosed
          except as may be permitted under Clause 18. Nothing in this Clause
          13.5(a) applies to or in relation to or restricts in any way:

          (1)       disclosure of information to the Expert; or

          (2)       disclosure of the matter for determination or the
                    determination in the course of legal proceedings or in the
                    course of any other judicial, arbitral or administrative
                    proceedings (including proceedings before an arbitrator)
                    between the Parties.

(b)       It will be a term of the Expert's appointment that the Expert be
          required to undertake to keep confidential matters coming to his or
          her knowledge by reason of his or her appointment and carrying it out,
          for a period ending no earlier than the date which is five years after
          the termination of the Master Agreement.

13.6      REMOVAL OF EXPERT

If an Expert appointed under this Clause 13 has not arrived at a determination
within three Months of the date of his or her appointment, any Party to the
determination may, upon giving notice to the other, terminate such appointment


                                       53
<PAGE>


and a new Expert must be appointed and the matter in dispute must be resubmitted
for determination in accordance with this Clause 13.

13.7      REFERRAL TO EXPERT DOES NOT AFFECT OBLIGATIONS

The referral of a dispute or difference to an Expert pursuant to this Clause 13
will not affect the obligations of the Parties to supply or take Gas in
accordance with the terms and conditions of this Agreement.

13.8      COMMUNICATIONS TO BE COPIED TO OTHER PARTY

Any communication by one Party with the Expert (whether pursuant to Clause 13.4
or otherwise) must be copied, at the same time, to the other Party.

20.       SEVERANCE
--------------------------------------------------------------------------------

20.1      GENERAL CASE

(a)       If the whole or any part of a provision of this Agreement is or
          becomes void, unenforceable or illegal or otherwise contravenes any
          law or statute, it is severed from this Agreement and the remainder of
          this Agreement continues in full force and effect.

(b)       If the severance referred to in Clause 20. 1 (a) would alter the basic
          nature of this Agreement (other than a Party's right to information),
          this Agreement will be deemed to have terminated on the date upon
          which the Parties first become aware of the provision being void,
          unenforceable or illegal or otherwise contravening any law or statute.

20.2      EXEMPTION EVENT

(a)       If any Party becomes aware that the Exemption is likely to be repealed
          or amended or to cease to apply to any of the Sellers, the Agent,
          Gascor and this Agreement or to lapse within 3 months (the occurrence
          of each such event being an ("EXEMPTION EVENT"), that Party must
          notify the other Party. The Parties must meet within 5 Working Days of
          such notice to discuss the potential Exemption Event.

(b)       (1)       If following a meeting pursuant to Clause 20.2(a), a
                    Party reasonably considers that the Exemption Event may
                    result in that Party being in contravention of Part IV of
                    the Trade Practices Act 1974, the Party may so notify the
                    other Party and the Parties must then jointly brief, as soon
                    as reasonably practicable, a Senior Counsel or equivalent
                    (experienced in matters relating to the Trade Practices Act
                    1974) to advise on the likelihood of such a contravention.

          (2)       If the Parties are unable to agree on counsel within 5
                    Working Days of a Party's notice under Clause 20.2(b)(1),
                    any Party may request that the Chairman of the Victorian Bar
                    Council nominate counsel and such nomination will be binding
                    on the Parties.

20.3      NEW AGREEMENT

(a)       If either:

          (1)       this Agreement is terminated pursuant to Clause 20. 1 (b) or

          (2)       the advice obtained from counsel pursuant to Clause 20.2(b)
                    confirms the likelihood of a contravention of Part IV of the
                    Trade Practices Act 1974 upon the occurrence of the
                    Exemption Event, and the Exemption has not been replaced by
                    another regulation, enactment or arrangement having the same
                    effect as the Exemption,


                                       65
<PAGE>

          the Parties must meet as soon as possible thereafter and negotiate in
          good faith with the intent of agreeing the terms of a new agency
          agreement on terms and conditions (including without limitation price)
          similar to those in this Agreement taking into account the effect of
          those provisions that contravene or are likely in any Party's
          reasonable opinion to contravene the provisions of Part IV of the
          Trade Practices Act 1974.

(b)       Negotiations commenced under Clause 20.3(a)(2) may cease upon it
          becoming apparent that:

          (1)       the Exemption will not be repealed, amended, cease to apply
                    or lapse;

          (2)       the Exemption has been replaced by another regulation,
                    enactment or arrangement having the same effect as the
                    Exemption; or

          (3)       the Exemption is not required in order to prevent a Party
                    being in contravention of Part IV of the Trade Practices Act
                    1974.

(c)       If:

          (1)       the Parties have not agreed the terms of a new agreement
                    within 60 days after the occurrence of an Exemption Event;

          (2)       the Exemption has not been replaced by another regulation,
                    enactment or arrangement having the same effect as the
                    Exemption; and

          (3)       it has not become apparent that the Exemption is not
                    required in order to prevent the Party seeking to utilise
                    this Clause 20.3(c) being a contravention of Part IV of the
                    Trade Practices Act 1974,

                    a Party may by notice to the other Party terminate this
                    Agreement with effect from the later of:

                    (A)       the Exemption being repealed, amended, ceasing to
                              apply to each of the Agent, Gascor and this
                              Agreement or lapsing; and

                    (B)       the date of such notice.

                                   SCHEDULE 2

                               ACCOUNTING POLICIES


The following accounting policies must be used for the purpose of preparing the
Agency Records:

1.        SALES REVENUE

Sales revenue for a Month is:

(a)       the aggregate amount, expressed in dollars, invoiced in that Month by
          the Agent to Gascor Customers in respect of Gas including Related
          Charges; plus

(b)       the sales revenue accrual for unbilled Gas supplied to Gascor
          Customers in the Month determined as follows:

          (1)       at the end of the Month, the accrual is the quantity of Gas
                    supplied to Gascor Customers which has not been billed to
                    those customers converted to revenue based on the prevailing
                    Tariff Order or December 1997 Tariff Order;

          (2)       the amount of the accrual must be reconcilable to the total
                    quantity of Gas deemed to be made available to the Agent in
                    the Month under this Agreement and purchased by the Agent
                    from other persons, after making adjustments for the
                    reversal of the closing accrual for the preceding Month, the
                    billed revenue in the Month and unaccounted for gas;

          (3)       the accrual must be calculated by applying both the fixed
                    and variable charges contained within the prevailing tariff
                    to the quantity of Gas referred to in paragraph (1)(b)(1);
                    less

(c)       the closing accrual for the preceding Month.

2.        BAD AND DOUBTFUL DEBTS

(a)       A specific provision must be made for the entire amounts of bad and
          doubtful debts that remain outstanding [THIS PARAGRAPH CONTAINS
          CONFIDENTIAL INFORMATION WHICH HAS BEEN OMITTED, BUT FILED SEPARATELY
          WITH THE SECURITIES AND EXCHANGE COMMISSION.] days or more after the
          relevant invoice date.

(b)       A reversal of the provision for bad and doubtful debts must be made to
          the extent that debts previously classified as bad or doubtful are
          subsequently collected.

(c)       Gascor, in consultation with the Agent, will determine at least
          annually which debts that have previously been provided for will be


                                       71
<PAGE>


          written off and will advise the Agent when provisions in respect of
          such debts are to be removed from the bad debt provision.

                          SCHEDULE 3 - RETAINED PROFIT

                                     PART 1

                         CALCULATION OF RETAINED PROFIT

1.        The amount of profit ("RETAINED PROFIT") which Gascor will retain in
          each Month during the Contract Term (being variable RPM in the formula
          contained in Clause 6.3) will be calculated as follows:

          [THIS PARAGRAPH CONTAINS CONFIDENTIAL INFORMATION WHICH HAS BEEN
          OMITTED, BUT FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
          COMMISSION.]

          Where:

          RPM       is the amount of the Retained Profit for a Month ("MONTHM");

          AM        is the amount ("COMPONENT A") calculated in accordance with
                    paragraph 2 of Part 1 of this Schedule for MonthM; and

          BM        is the amount ("COMPONENT B") calculated in accordance with
                    paragraphs 3 to 5 (inclusive) of Part 1 of this Schedule for
                    MonthM;

          provided that if [THIS PARAGRAPH CONTAINS CONFIDENTIAL INFORMATION
          WHICH HAS BEEN OMITTED, BUT FILED SEPARATELY WITH THE SECURITIES AND
          EXCHANGE COMMISSION.] is less than zero, RPM shall be deemed to be
          zero.

2.        Component A for MonthM is calculated as follows:

          [THIS PARAGRAPH CONTAINS CONFIDENTIAL INFORMATION WHICH HAS BEEN
          OMITTED, BUT FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
          COMMISSION.]

          Where:

          AM        is Component A for MonthM;

          AMB       is the amount set out in column 2 of Part 2 of this Schedule
                    against MonthM;

          CPINt-1 is the Consumer Price Index (All Groups - weighted average of
          eight capital cities), as first published by the Australian Bureau of
          Statistics for the Quarter ended 30 September in the calendar year
          immediately prior to the Contract Year in which MonthM falls or, if
          MonthM falls in the Contract Year ending on [THIS PARAGRAPH CONTAINS
          CONFIDENTIAL INFORMATION WHICH HAS BEEN OMITTED, BUT FILED SEPARATELY
          WITH THE SECURITIES AND EXCHANGE COMMISSION.], [THIS PARAGRAPH
          CONTAINS CONFIDENTIAL INFORMATION WHICH HAS BEEN OMITTED, BUT FILED
          SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION.]; and


                                       73
<PAGE>


          CPIBN is the base Consumer Price Index (All Groups - weighted average
          of eight capital cities) being [THIS PARAGRAPH CONTAINS CONFIDENTIAL
          INFORMATION WHICH HAS BEEN OMITTED, BUT FILED SEPARATELY WITH THE
          SECURITIES AND EXCHANGE COMMISSION.] (the Consumer Price Index (All
          Groups - weighted average of eight capital cities) for the Quarter
          ended [THIS PARAGRAPH CONTAINS CONFIDENTIAL INFORMATION WHICH HAS BEEN
          OMITTED, BUT FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
          COMMISSION.].

3.        Prior to the end of each Contract Year (or, if the relevant CPI data
          is not available, as soon as reasonably practicable after the relevant
          CPI data becomes available) an estimate of Component B to apply for
          each Month in the following Contract Year will be made by Gascor by
          applying the following formula:

          [THIS PARAGRAPH CONTAINS CONFIDENTIAL INFORMATION WHICH HAS BEEN
          OMITTED, BUT FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
          COMMISSION.]

          Where:

          BM        is the estimated amount of Component B for MonthM;

          BMB       is the amount set out in column 3 of Part 2 of this Schedule
                    against MonthM;

          CPIEt     is the estimated CPI for the Contract Year in which MonthM
                    falls, being equal to CPIE (as defined in paragraph (a) of
                    Schedule 4 to the Principal Contract) for that year; and

          CPIAB     is the actual CPI for the [THIS PARAGRAPH CONTAINS
                    CONFIDENTIAL INFORMATION WHICH HAS BEEN OMITTED, BUT FILED
                    SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION.]
                    calendar year (being the arithmetic average, rounded to the
                    third decimal place, of the CPI for each of the four
                    Quarters of that calendar year), being equal to CPIA (as
                    defined in paragraph (c) of Schedule 4 to the Principal
                    Contract) for that year.

4.        For the purposes of calculating the Retained Profit during each
          Contract Year (as itemised in the Monthly Claim Forms), Component B
          will be calculated on the basis of the estimated amount of Component B
          as determined in accordance with paragraph 3 of Part 1 of this
          Schedule

5.        If the estimated amount of Component B for January in any Contract
          Year cannot be determined in accordance with paragraph 3 of Part 1 of
          this Schedule by the date on which the Agent must give a Statement for
          that month because of the unavailability of CPIEt, the Agent must, for
          the purpose of calculating the estimated amount of Component B for
          that month, use, in place of CPIEt, the estimated CPI for the previous
          Contract Year and make appropriate reconciliation in the next Monthly
          Claim Form.

6.        Promptly after the CPI for each year becomes available (generally
          during the third week in January of the following year), the actual
          amount of Component B applicable for each Month in the Contract Year
          just ended will be calculated by Gascor in accordance with the
          following formula:


                                       74
<PAGE>


          [THIS PARAGRAPH CONTAINS CONFIDENTIAL INFORMATION WHICH HAS BEEN
          OMITTED, BUT FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
          COMMISSION.]

          Where:

          RB        is the actual amount of Component B for MonthM;

          BMB       is as defined in paragraph 3 of Part 1 of this Schedule;

          CPIAt     is the actual CPI for that year, being equal to CPIA (as
                    defined in paragraph (c) of Schedule 4 to the Principal
                    Contract) for that year; and

          CPIAB     is as defined in paragraph 3 of Part 1 of this Schedule.

7.        After calculating the actual amount of Component B for each Month in a
          Contract Year in accordance with paragraph 5 of Part 1 of this
          Schedule, Gascor must calculate the difference between the aggregate
          estimated amounts of Component B for each Month of that Contract Year
          and the aggregate actual amounts of Component B for each Month of that
          Contract Year ("RECONCILIATION AMOUNT").

8.        The Reconciliation Amount determined in respect of a Contract Year in
          accordance with paragraph 6 of Part 1 of this Schedule will be taken
          into account in the next Annual Statement in accordance with Clause
          6.8(e)(3)(B) of this Agreement.

                                     PART 3

                          VARIATION OF RETAINED PROFIT

1.        The Parties acknowledge that the method of calculating the Retained
          Profit as set out in Part 1 of this Schedule assumes that the
          Contestability Dates will be as follows:

          CONTESTABILITY DATE                   CUSTOMER LOAD (GIGAJOULES)

          1 October 1999                        more than 500,000
          1 March 2000                          100,000 to 499,999
          1 September 2000                      5,000 to 99,999
          1 September 2001                      All remaining customers


2.        If:

          (d)       there is any change in any Contestability Date; or

          (e)       any increase in the reference tariffs of Transmission
                    Pipelines Australia Pty Ltd (ACN 079 089 268) or
                    Transmission Pipelines Australia (Assets) Pty Ltd (ACN 079
                    136 413) (together, or separately, "TPA"), as set out in the
                    access arrangements of TPA relating to the principal
                    transmission system approved by the ACCC under the Code on
                    18 December 1998, made in recognition of the capital costs
                    incurred by TPA in constructing or commissioning the
                    existing transmission pipeline between Barnawartha in
                    Victoria and Culcairn in New South Wales or the
                    construction, installation or commissioning of the proposed
                    new compressor at Springhurst,

          (each a "VARIATION EVENT")

          then the Base Amounts will be varied to take account of the Variation
          Event in accordance with paragraphs 3 to 9 (inclusive).

3.        If Gascor considers that a Variation Event is likely to occur, or a
          Variation Event has occurred, Gascor must appoint KPMG of 161 Collins
          Street, Melbourne Vic 3000 or, if KPMG are unable to accept the
          appointment, such member of The Institute of Chartered Accountants in
          Australia or the Australian Society of Certified Practising
          Accountants as the Parties may agree (such agreement not to be
          unreasonably withheld or delayed) ("REVIEWING ACCOUNTANT") to
          determine the variations required to be made to the Base Amounts as a
          result of the Variation Event.

4.        For the purposes of determining the variations required to be made to
          the Base Amounts, the Reviewing Accountant must use the ["Gascor
          Retained Profit"] model developed and used by KPMG for the purposes of
          determining the Base Amounts and must use the same assumptions and
          inputs as were used for the purposes of determining the Base Amounts,
          save to the extent that, in the Reviewing Accountants' reasonable


                                       78
<PAGE>


          opinion, the assumptions and inputs have or need to be changed to take
          account of the Variation Event.

5.        It must be a term of the appointment of the Reviewing Accountant that
          the Reviewing Accountant must not disclose to the Agent any
          information relating to the determination or variation of another
          Retailer's Base Amounts (as defined in that Retailer's Agency
          Agreement).

6.        The Reviewing Accountant will be deemed not to be an arbitrator, but
          shall give its decision as an expert and its decision shall be final
          and binding on the Parties in the absence of fraud or manifest error.

7.        The costs and expenses of the Reviewing Accountant must be borne by
          Gascor.

8.        Any variation of the Base Amounts as determined in accordance with
          paragraphs 2 to 4 (inclusive), will take effect from the date on which
          the Variation Event occurred, whether or not the variation is
          determined by the Reviewing Accountant before or after that date, and,
          for the avoidance of doubt, the Reviewing Accountant may vary the Base
          Amounts with retrospective effect (in which case the Reviewing
          Accountant must specify, and the Parties must give effect to, any
          necessary reconciliation).

9.        For the purposes of this Part 4, a variation of the Base Amounts may
          include a reduction or increase in the length of the period in respect
          of which Base Amounts (as varied) are calculated commensurate with the
          Contract Term.

1.        For the purposes of this Part 4:

          "FAILURE OF SUPPLY" means a total failure by the Sellers to supply any
          Gas at the Point of Delivery for a period of at least [THIS PARAGRAPH
          CONTAINS CONFIDENTIAL INFORMATION WHICH HAS BEEN OMITTED, BUT FILED

          hours.

2.        If, in any Month during the Contract Term (other than a Month ending
          on or prior to [THIS PARAGRAPH CONTAINS CONFIDENTIAL INFORMATION WHICH
          HAS BEEN OMITTED, BUT FILED SEPARATELY WITH THE SECURITIES AND
          EXCHANGE COMMISSION.]), there is a Failure of Supply (whether that
          Failure of Supply commences before or during that Month), the Retained
          Profit for that Month ("MONTHM") shall be adjusted as follows:

          [THIS PARAGRAPH CONTAINS CONFIDENTIAL INFORMATION WHICH HAS BEEN
          OMITTED, BUT FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
          COMMISSION.]

          ARP       is the amount of the Retained Profit for MonthM as adjusted;

          RPM       is the amount of the Retained Profit for MonthM as
                    calculated in accordance with Part 1 of this Schedule;

          HM        is the [THIS PARAGRAPH CONTAINS CONFIDENTIAL INFORMATION
                    WHICH HAS BEEN OMITTED, BUT FILED SEPARATELY WITH THE
                    SECURITIES AND EXCHANGE COMMISSION.] in MonthM; and

          HF        is the [THIS PARAGRAPH CONTAINS CONFIDENTIAL INFORMATION
                    WHICH HAS BEEN OMITTED, BUT FILED SEPARATELY WITH THE
                    SECURITIES AND EXCHANGE COMMISSION.] in MonthM during which
                    the Sellers totally failed to supply any Gas at the Point of
                    Delivery.

                              ESTIMATION PROCEDURES

The estimated quantity of Gas supplied to each Contestable Customer in the
Agency Area in a Month will be determined by calculating the quantity of Gas,
expressed in GJ, underlying the sales revenue generated by the Agent from that
Contestable Customer in that Month.

The procedures for determining the estimated quantity of Gas supplied by the
Agent to a Contestable Customer in the Agency Area in a Month, as required for
the purposes of Clause 6.4(a), are as follows:

1.        The quantity of Gas invoiced to the Contestable Customer in a Month
          must be determined and the number of days covered by the invoice must
          be converted into equivalent days by treating weekend days and public
          holidays as [THIS PARAGRAPH CONTAINS CONFIDENTIAL INFORMATION WHICH
          HAS BEEN OMITTED, BUT FILED SEPARATELY WITH THE SECURITIES AND
          EXCHANGE COMMISSION.] instead of unity (except where there are other
          consumption patterns). The invoiced quantity will then be divided by
          the number of equivalent days to obtain a GJ/equivalent day amount.

2.        The number of days from but excluding the day on which the Contestable
          Customer's meter was last read to and including the last day of the
          Month in respect of which the estimate is being determined will be
          converted into equivalent days and an accrual will be calculated by
          multiplying the number of equivalent days by the GJ/equivalent day
          amount.

3.        The estimated quantity of Gas supplied in a Month to the Contestable
          Customer will then be determined by taking the aggregate quantity,
          expressed in GJ, invoiced to the Contestable Customer in that Month
          and adding an accrual for the estimated quantity of unbilled Gas
          supplied to the Contestable Customer in that Month, as determined in
          accordance with paragraph 2, and deducting the accrual, as determined
          in respect of the Contestable Customer in accordance with paragraphs 1
          and 2 for the preceding Month.
