          (3)       the Buyer under Clause 4.3(b), 4.3(d) or 4.5(b) of its

(c)       If Gascor is informed by the Sellers pursuant to Clause 5.5(b) of the
          Principal Contract of the Sellers' best estimate of the quantity of
          Gas which the Sellers will be able to deliver on the Day following the

3.8       QUANTITY OF GAS DELIVERED UNDER THIS AGREEMENT

(a)       The quantity of Gas delivered by Gascor to the Buyer under this
          Agreement in a Gas Month ("QB") shall be calculated as follows:

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

          Where:

          Qt        is the total quantity of Gas, expressed in GJ, allocated to
                    the Buyer in respect of that Gas Month pursuant to Clause
                    7.1(b) of the Master Agreement; and

          Qa        is the quantity of Gas (if any), expressed in GJ, delivered
                    by Gascor to the Buyer in that Gas Month under the Buyer's
                    Agency Agreement as determined in accordance with Clause
                    6.4(a) of that agreement.

(b)       If and for so long as any Gas is supplied to a Retailer under its
          Agency Agreement the Buyer must calculate Qb for each Gas Month and
          notify Gascor of its calculation in writing on or before the 12th day
          of the following Gas Month.

(c)       If Qb in respect of a Gas Month is recalculated by the Buyer pursuant
          to Clause 7.2(b) or (c) of the Master Agreement, the next Monthly
          Statement to be given by Gascor to the Buyer under Clause 8. 1 (a)
          must contain:

          (1)       a detailed reconciliation of (on the one hand) the amount
                    paid for Gas by the Buyer for that Gas Month in accordance
                    with the Monthly Statement for that Gas Month against (on
                    the other hand) the amount which should have been paid for
                    Gas by the Buyer for that Gas Month on the basis of Qb as
                    recalculated pursuant to Clause 7.2(b) or (c) of the Master
                    Agreement; and

          (2)       the amount payable by one Party to the other Party following
                    the reconciliation referred to in Clause 3.8(c)(1) so as to
                    ensure that the amount paid by the Buyer for Gas in respect
                    of that Gas Month reflects the quantity of Gas delivered
                    during that Gas Month under this Agreement.

(d)       If Qa is recalculated or redetermined by the Buyer in accordance with
          Clause 6.5(b) of the Buyer's Agency Agreement, the recalculated or
          redetermined quantity must be taken into account in the next Monthly


                                       19
<PAGE>


          Statement to the extent that it has the effect of increasing or
          reducing Qb.

(e)       If the Buyer fails to notify Gascor of its calculation of Qb in
          accordance with Clause 3.8(b) by the time specified in that Clause,
          the Buyer must pay interest at the Default Rate on the net sum payable
          by the Buyer to Gascor as specified in the next Monthly Statement from
          (but excluding) the date on which Gascor should have given a Monthly
          Statement containing a statement of Qb for that Gas Month until (and
          including) the date on which Gascor gives a Monthly Statement which
          contains a statement of Qb for that Gas Month.

3.9       ALTERNATE GAS

(a)       If Gascor is deemed to have failed to have delivered to the Buyer
          under this Agreement any quantity of Gas in accordance with Clause
          7.12 of the Master Agreement ("UNDELIVERED GAS"), the Buyer may
          purchase on behalf of Gascor a quantity of Sales Gas ("ALTERNATE GAS")
          in lieu of all or part of the Undelivered Gas.

(b)       If the Buyer purchases Alternate Gas on behalf of Gascor pursuant to
          Clause 3.9(a), the Buyer must pay on behalf of Gascor all costs
          relating to the purchase and transportation of the Alternate Gas,
          provided that Gascor shall, subject to Clause 13.6 of the Master
          Agreement, reimburse the Buyer such costs if and to the extent that
          Gascor is entitled to recover compensation from the Sellers under
          Clause 23.4 of the Principal Contract for the sum of:

          (1)       the excess cost to Gascor of that quantity of Alternate Gas
                    over the amount that would have been paid by Gascor to the
                    Sellers for the quantity of Undelivered Gas equivalent to
                    that quantity of Alternate Gas on the basis that the
                    Undelivered Gas would have been C Market Gas (as defined in
                    the Principal Contract); and

          (2)       the net cost or benefit of transporting that quantity of
                    Alternate Gas.

(c)       Gascor shall execute such agreements as the Buyer may reasonably
          request to enable Gascor to recover compensation from the Sellers (in
          the event of a failure by the Sellers to deliver under the Principal
          Contract any quantity of Gas which they are obliged to deliver) in
          respect of any fixed costs or direct damages which, if incurred by the
          Buyer, would not be recoverable by Gascor under the Principal
          Contract, provided that the Buyer indemnifies Gascor and keeps Gascor
          indemnified from and against any claim, action, damage, loss,
          liability, cost, charge, expense, outgoing or payment which Gascor
          pays, suffers, incurs or is liable for in connection with entering
          into such arrangements or agreements.

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 Sellers, the Buyer, 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,


                                       43
<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 agreement
          for the supply of gas 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 Buyer, Gascor and this
                              Agreement or lapsing; and

                    (B)       the date of such notice.

                    quantity of the Buyer's MDQ reduction for a Month is
                    calculated by adding the quantities of the Buyer's MDQ

(c)       The Monthly instalment in respect of each Month is payable in
          accordance with Clause 8.
