        FOR
VALUE RECEIVED, the undersigned, Questar Market Resources, Inc., a Utah corporation (herein called "Borrower"), hereby promises to pay to the order of SUNTRUST BANK (herein
called "Lender"), the principal sum of                        Dollars
(US$                        ), or, if greater or less, the aggregate unpaid principal amount of the Tranche B Loans made under
this Note by Lender
to Borrower pursuant to the terms of the Credit Agreement (as hereinafter defined), together with interest on the unpaid principal balance thereof as hereinafter set forth, both principal and interest
payable as herein provided in lawful money of the United States of America at the offices of US Agent under the Credit Agreement, 901 Main Street, Dallas, Texas or at such other place within Dallas
County, Texas, as from time to time may be designated by the holder of this Note. 


        This
Note (a) is issued and delivered under that certain US Credit Agreement dated as of April 19, 1999 among Borrower, Bank of America, N.A., individually and as
administrative agent ("US Agent"), and the lenders (including Lender) referred to therein (herein, as from time to time supplemented, amended or restated, called the "Credit Agreement"), and is a
"Tranche B Note" as defined therein, (b) is subject to the terms and provisions of the Credit Agreement, which contains provisions for payments and prepayments hereunder and acceleration of the
maturity hereof upon the happening of certain stated events, and (c) is given in partial renewal and extension (but not in extinguishment or novation) of (i) that certain Promissory Note
dated April 17, 2000, executed and delivered by Borrower and payable to the order of Toronto Dominion (Texas), Inc., in the stated principal amount of US $3,333,333.33, (ii) that
certain Promissory Note dated April 17, 2000, executed and delivered by Borrower and payable to the order of The Industrial Bank of Japan, Limited, in the stated principal amount of US
$1,666,666.67, and (iii) that certain Promissory Note dated April 17, 2000, executed and delivered by Borrower and payable to the order of Sumitomo Mitsui Banking Corporation, formerly
known as The
Sumitomo Bank, Limited, in the stated principal amount of US $1,666,666.67. Payments on this Note shall be made and applied as provided herein and in the Credit Agreement. Reference is hereby made to
the Credit Agreement for a description of certain rights, limitations of rights, obligations and duties of the parties hereto and for the meanings assigned to terms used and not defined herein. 


        The
principal amount of this Note, together with all interest accrued hereon, shall be due and payable in full on the Tranche B Maturity Date. 


        Tranche
B Loans that are US Base Rate Loans (exclusive of any past due principal or interest) from time to time outstanding shall bear interest on each day outstanding at the US Base
Rate in effect on such day; provided that if an Event of Default has occurred and is continuing, US Base Rate Loans shall bear interest on each day outstanding at the applicable Default Rate in effect
on such day. On each Interest Payment Date Borrower shall pay to the holder hereof all unpaid interest which has accrued on the US Base Rate Loans to but not including such Interest Payment Date. Each
Tranche B Loan that is a US Dollar Eurodollar Loan (exclusive of any past due principal or interest) shall bear interest on each day during the related Interest Period at the related Adjusted US
Dollar Eurodollar Rate in effect on such day; provided that if an Event of Default has occurred and is continuing, such US Dollar Eurodollar Loan shall bear interest on each day outstanding at the
applicable Default Rate in effect on such day. On each Interest Payment Date relating to such US Dollar Eurodollar Loan, Borrower shall pay to the holder hereof all unpaid interest which has accrued
on such US Dollar Eurodollar Loan to but not including such Interest Payment Date. 



        All

foregoing subsection (a) or by reference to the Highest Lawful Rate in the definitions of US Base Rate, Adjusted US Dollar Eurodollar Rate, and Default Rate), this Note shall bear interest at
the Highest Lawful Rate and shall continue to bear interest at the Highest Lawful Rate until such time as the total amount of interest accrued hereon equals (but does not exceed) the total amount of
interest which would have accrued hereon had there been no Highest Lawful Rate applicable hereto. 


        Notwithstanding
the foregoing paragraph and all other provisions of this Note, in no event shall the interest payable hereon, whether before or after maturity, exceed the maximum amount
of interest which, under applicable Law, may be charged on this Note, and this Note is expressly made subject to the provisions of the Credit Agreement which more fully set out the limitations on how
interest accrues hereon. The term "applicable Law" as used in this Note shall mean the laws of the State of Utah or the laws of the United States, whichever laws allow the greater interest, as such
laws now exist or may be changed or amended or come into effect in the future. 


        If
this Note is placed in the hands of an attorney for collection after default, or if all or any part of the indebtedness represented hereby is proved, established or collected in any
court or in any bankruptcy, receivership, debtor relief, probate or other court proceedings, Borrower and all endorsers, sureties and guarantors of this Note jointly and severally agree to pay
reasonable attorneys' fees and collection costs to the holder hereof in addition to the principal and interest payable hereunder. 



        Borrower
and all endorsers, sureties and guarantors of this Note hereby severally waive demand, presentment, notice of demand and of dishonor and nonpayment of this Note, protest, notice
of protest, notice of intention to accelerate the maturity of this Note, declaration or notice of acceleration of the maturity of this Note, diligence in collecting, the bringing of any suit against
any party and any notice of or defense on account of any extensions, renewals, partial payments or changes in any manner of or in this Note or in any of its terms, provisions and covenants, or any
releases or substitutions of any security, or any delay, indulgence or other act of any trustee or any holder hereof, whether before or after maturity. 



        THIS NOTE AND THE RIGHTS AND DUTIES OF THE PARTIES HERETO SHALL BE GOVERNED BY THE LAWS OF THE STATE OF UTAH (WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW),
EXCEPT TO THE EXTENT THE SAME ARE GOVERNED BY APPLICABLE FEDERAL LAW.

made to the Credit Agreement for a description of certain rights, limitations of rights, obligations and duties of the parties hereto and for the meanings assigned to terms used and not defined
herein. 


        For
the purposes of this Note, "Competitive Bid Rate Payment Date" means, with respect to each Competitive Bid Loan: (i) the day on which the related Competitive Bid Interest
Period ends, and (ii) any day on which past due interest or past due principal is owed hereunder with respect to such Competitive Bid Loan and is unpaid. If the terms hereof or of the Credit
Agreement provide that payments of interest or principal with respect to such Competitive Bid Loan shall be deferred from one Competitive Bid Rate Payment Date to another day, such other day shall
also be a Competitive Bid Rate Payment Date. 


        The
principal amount of this Note and interest accrued hereon, shall be due and payable as set forth in the Credit Agreement, and shall in any event be due in full on the last day of the
US Facility Commitment Period. 


        Each
Competitive Bid Loan (exclusive of any past due principal or past due interest) shall bear interest on each day during the related Competitive Bid Interest Period at the Competitive
Bid Rate in effect on such day for such Competitive Bid Loan, provided that if an Event of Default has occurred and is continuing such Competitive Bid Loan shall bear interest on each day outstanding
at the applicable Default Rate in effect on such day. On each Competitive Bid Rate Payment Date relating to any Competitive Bid Loan, Borrower shall pay to the holder hereof all unpaid interest which
has accrued on such Competitive Bid Loan to but not including such Competitive Bid Rate Payment Date. 


        All
past due principal of and past due interest on Competitive Bid Loans shall bear interest on each day outstanding at the applicable Default Rate in effect on such day, and such
interest shall be due and payable daily as it accrues. Notwithstanding the foregoing provisions of this paragraph: (a) this Note shall never bear interest in excess of the Highest Lawful Rate,
and (b) if at any time the rate at which interest is payable on this Note is limited by the Highest Lawful Rate (by the foregoing clause (a) or by reference to the Highest Lawful Rate in
the definitions of Competitive Bid Rate and Default Rate), this Note shall bear interest at the Highest Lawful Rate and shall continue to bear interest at the Highest Lawful Rate until such time as
the total amount of interest accrued hereon 









equals (but does not exceed) the total amount of interest which would have accrued hereon had there been no Highest Lawful Rate applicable hereto. 


        Notwithstanding
the foregoing paragraph and all other provisions of this Note, in no event shall the interest payable hereon, whether before or after maturity, exceed the maximum amount
of interest which, under applicable Law, may be charged on this Note, and this Note is expressly made subject to the provisions of the Credit Agreement which more fully set out the limitations on how
interest accrues hereon. The term "applicable Law" as used in this Note shall mean the laws of the State of Utah or the laws of the United States, whichever laws allow the greater interest, as such
laws now exist or may be changed or amended or come into effect in the future. 


        If
this Note is placed in the hands of an attorney for collection after default, or if all or any part of the indebtedness represented hereby is proved, established or collected in any
court or in any bankruptcy, receivership, debtor relief, probate or other court proceedings, Borrower and all endorsers, sureties and guarantors of this Note jointly and severally agree to pay
reasonable attorneys' fees and collection costs to the holder hereof in addition to the principal and interest payable hereunder. 


        Borrower
and all endorsers, sureties and guarantors of this Note hereby severally waive demand, presentment, notice of demand and of dishonor and nonpayment of this Note, protest, notice
of protest, notice of intention to accelerate the maturity of this Note, declaration or notice of acceleration of the maturity of this Note, diligence in collecting, the bringing of any suit against
any party and any notice of or defense on account of any extensions, renewals, partial payments or changes in any manner of or in this Note or in any of its terms, provisions and covenants, or any
releases or substitutions of any security, or any delay, indulgence or other act of any trustee or any holder hereof, whether before or after maturity. 


        THIS NOTE AND THE RIGHTS AND DUTIES OF THE PARTIES HERETO SHALL BE GOVERNED BY THE LAWS OF THE STATE OF UTAH (WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW),
EXCEPT TO THE EXTENT THE SAME ARE GOVERNED BY APPLICABLE FEDERAL LAW.
