                     THE MASTER FIRM PURCHASE/SALE AGREEMENT
                                 BY AND BETWEEN

                      PG & E ENERGY TRADING-GAS CORPORATION
                                      DATED
                                NOVEMBER 1, 1999


This Amendment, (the "Amendment") to that certain Master Firm Purchase/Sale
Agreement between Bluefield Gas Company, a West Virginia corporation ("BGC"),
and PG & E Energy Trading-Gas Corporation, a California corporation ("Energy
Trading"), dated November 1, 1999 (the "Master Firm Agreement"), is entered into
by BGC and ENERGY TRADING, effective as of November 1, 1999.

        WHEREAS, BGC and ENERGY TRADING have entered into a Letter of Intent,
dated October 18, 1999, pursuant to which ENERGY TRADING has agreed to manage
all of BGC's natural gas, transportation and storage assets, exclusive of LNG
facilities;

        WHEREAS, ENERGY TRADING's asset management shall include its assumption
of 100% of BGC's natural gas requirements up to 15,740/dth per day, on a firm
uninterruptible basis;

        WHEREAS, a portion of BGC's gas requirements will be pulled from storage
and on any given day the contract withdrawal plan may differ from physical
storage activities, and a portion of such requirements may be sold to BGC by
ENERGY TRADING under the terms of the Master Firm Agreement; and

        WHEREAS, to further facilitate ENERGY TRADING's management of BGC's
assets, the parties desire to amend the Master Firm Agreement to (i) govern
ENERGY TRADING's asset management responsibilities, including management of
BGC's storage capacity located at the storage facilities listed on Exhibit A
hereto and (ii) .458271 Bcf of natural gas owned by BGC and stored at the
storage facilities (the "Storage Assets"), which Storage Assets shall then be
loaned back and forth between the parties during the term thereof.

        NOW, THEREFORE, in consideration of the mutual covenants herein
contained, BGC and ENERGY TRADING agree as follows:

        1.     ARTICLE 1. TERM of the Master Firm Agreement is hereby deleted in
               its entirety and replaced by the following:







               "ARTICLE 1. TERM.  This Master Firm Agreement shall govern all
               Transactions for (i) the firm purchase or sale of gas between the
               parties, and (ii) ENERGY TRADING's management of BGC's Storage
               Assets under Article 9 hereof, to be in effect until October 31,
               2000. At ENERGY TRADING's sole election, the term of this Master
               Firm Agreement may be extended through October 31, 2001. Should
               ENERGY TRADING elect to extend this Master Finn Agreement, it
               must give notice to BGC prior to the close of business on
               February 29, 2000. Both parties agree that if the Master Firm
               Agreement is extended, and BGC so desires, they will negotiate in
               good faith to develop a plan for Energy Trading to take title to
               BGC's storage capacity and stored gas until delivery to BGC's
               citygate. Termination of this Master Firm Agreement shall in all
               instances be subject to Section 8.4.

        2.     The Master Firm Agreement is hereby amended to add an ARTICLE 9.
               ASSET MANAGEMENT. Article 9 shall read as follows:

               "ARTICLE 9. ASSET MANAGEMENT. 9.1 Management Services. Beginning
               on November 1, 1999, ENERGY TRADING agrees to assume full
               responsibility for supplying 100% of BGC's natural gas
               requirements up to 15,740/dth per day, on a firm uninterruptible
               basis, and to provide asset management services to BGC, such
               services to be provided for the remainder of the term of this
               Master Firm Agreement.

               9.2 Limited Agency Appointment. In order to facilitate ENERGY
               TRADING's management services, BGC hereby appoints ENERGY TRADING
               its limited agent for the purpose of nominating injections and
               withdrawals from storage, buying and selling natural gas on its
               behalf. As BGC's limited agent, ENERGY TRADING's role shall be
               one of independent contractor, and in no event shall the
               relationship between the parties be construed as a partnership,
               joint venture or full agency relationship. At all times during
               ENERGY TRADING's agency, title to all gas withdrawn from,
               purchased, sold or injected into storage shall reside with BGC.

               9.3 Management Fee Waiver. In lieu of any management fee payable
               to ENERGY TRADING for its asset management services hereunder,
               BGC waives all proceeds, if any, recognized by ENERGY TRADING in
               the management of the Storage Assets, other than the demand
               charge provided for in the Special Conditions section of the
               Transaction Confirmation.

               9.4 Inadequate Performance. Notwithstanding any other provisions
               in this Master Firm Agreement, BGC shall have a unilateral right
               to terminate this Master Firm Agreement before March 31, 2000,
               upon 10 days' notice to ENERGY TRADING, for inadequate
               performance. "Inadequate performance" shall only






               mean ENERGY TRADING's failure to supply the firm citygate natural
               gas volumes to BGC, as contracted by the parties unless ENERGY
               TRADING'S performance is excused under the Master Firm Agreement.

        3.     For purposes of incorporating this Amendment into the Master Finn
               Agreement, as between the parties, the term "Seller" shall refer
               to ENERGY TRADING, either in its own right or on behalf of BGC,
               and the terms "Buyer" and "Customer" shall refer to BGC.

        4.     The commercial terms of the Letter of Intent between the parties
               are incorporated herein by this reference and made a part hereof.

        5.     Except as set forth in this Amendment, the terms of the Master
               Firm Agreement are ratified and confirmed in all respects by the
               parties.

IN WITNESS WHEREOF, the parties have executed this Amendment effective as of the
1st day of November, 1999.
