"Borrower"),  and THE BANK OF NOVA SCOTIA ("Scotia Capital"),  as administrative
agent (in such capacity, the "Agent").

                              W I T N E S S E T H:

     WHEREAS,  the Borrower and Scotia Capital have heretofore  entered into (i)
the  Amended  and  Restated  Credit  Agreement,  dated as of July  16,  2003 (as
amended,  supplemented  or  otherwise  modified  from time to time,  the "Credit
Agreement"),  among the Borrower,  the various financial  institutions as are or
may become parties thereto (the "Participating Lenders"), and Scotia Capital, as
administrative agent and (ii) the L/C Agreement;

     WHEREAS,  on or about  September 2, 2004, all  outstanding  loans under the
Credit  Agreement were repaid by the Borrower,  all commitments  thereunder were
terminated  and all  outstanding  letters  of credit  issued  by Scotia  Capital
thereunder  (the  "Scotia  Letters  of  Credit")  and  participated  in by  each
Participating  Lender thereunder were fully cash collateralized  pursuant to the
Cash Collateral  Agreement,  dated as of September 2, 2004 (the "Cash Collateral
Agreement"),  made by the Borrower in favor of Scotia Capital,  in each case, as
required under the Credit Agreement, with the proceeds (the "Gas Sale Proceeds")
of the sale by the  Borrower  of certain  Designated  Assets (as  defined in the
Credit  Agreement),  which  Designated  Assets  constituted  collateral  for the
obligations of the Borrower under the Credit Agreement;

     WHEREAS,  the  Borrower  intends to issue  $785,000,000  of First  Priority

Trustee,  and to use a portion of the proceeds thereof (such portion,  the "Bond
Proceeds  Collateral")  to cash  collateralize  the Scotia  Letters of Credit as
replacement  cash  collateral  for the Gas Sale  Proceeds,  as set forth in this
Amendment;

     WHEREAS,  the Borrower and the Agent now desire to amend the L/C Agreement,
inter  alia,  to deem the Scotia  Letters of Credit  issued  pursuant to the L/C
Agreement rather than pursuant to the Credit Agreement, as hereinafter provided;

the  termination  of the Credit  Agreement,  its  release  of the  Participating
Lenders  and  the  Gas  Sale  Proceeds  and its  undertaking  of the  unilateral
obligation (rather than shared with the Participating Lenders) to pay any drafts
presented against the Scotia Letters of Credit,  the Borrower has agreed to cash
collateralize the Scotia Letters of Credit by substituting the Gas Sale Proceeds
under the Cash Collateral  Agreement with the Bond Proceeds Collateral hereunder
and under the L/C Agreement;
