QUESTAR GAS COMPANY, a corporation duly organized and existing under the laws of the State of Utah (herein called the "Company", which term includes any successor corporation under the Indenture hereinafter referred to), for value received, hereby promises to pay to CEDE & CO., or registered assigns, the principal sum of                        DOLLARS ($                        ) at Stated Maturity as specified above (except to the extent redeemed or repaid prior to the Stated Maturity), and to pay interest thereon from the Original Issue Date specified above or from the most recent Interest Payment Date (subject to the provisions below) to which interest has been paid or duly provided for, periodically on each Interest Payment Date, commencing with the first such Interest Payment Date next succeeding the Original Issue Date specified above, and at Stated Maturity (the date on each such Stated Maturity, Redemption Date, and Optional Repayment Date and the date on which principal or an installment of principal is due and payable by declaration of acceleration pursuant to the Indenture being referred to hereinafter as a "Maturity" with respect to principal payable on such date), at the Interest Rate specified above, until the principal hereof is paid or made available for payment; provided, that if such Original Issue Date is after a Regular Record Date and before the Interest Payment Date immediately following such Regular Record Date, interest payments will commence on the second Interest Payment Date following the Original Issue Date. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date (except at Maturity) will, as provided in the Indenture, be paid to the Person in whose name this Note (or one or more Notes which are Predecessor Securities) is registered at the close of business on the Regular Record Date next preceding such Interest Payment Date. Any such interest which is payable, but not so punctually paid or duly provided for on any Interest Payment Date, will forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Note (or one or more Notes which are Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to the Holder of this Note not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes of this series may be listed, upon such notice as may be required by such exchange, all as more fully provided in the Indenture. Reference herein to "this Note", "hereof", "herein" and comparable terms shall include an Addendum hereto if an Addendum is specified above.

        Any provision contained herein with respect to the calculation of the rate of interest applicable to this Note, its payment dates or any other matter relating hereto may be modified as specified in an Addendum relating hereto if so specified above.

will be made on the following day that is a Business Day with respect to this Note as if it were made on the date such payment was due and no interest shall accrue on the amount so payable for the period from and after such Interest Payment Date or Maturity, as the case may be. Unless otherwise specified on the first page of this Note, the Interest Rate on this Note will be computed on the basis of a 360-day year of twelve 30-day months.

        This Note will be redeemable as a whole or in part, at the option of the Company at any time, at a Redemption Price equal to the greater of (i) 100% of its principal amount and (ii) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus [    ] basis points, plus in each case accrued and unpaid interest thereon to the date of redemption.

        "Treasury Rate" means, with respect to any Redemption Date, the rate per annum equal to the semiannual equivalent yield to maturity or interpolated (on a day count basis) of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.

        "Comparable Treasury Issue" means the United States Treasury security or securities selected by an Independent Investment Banker as having a maturity or interpolated (on a day count basis) comparable to the remaining term of this Note that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of a comparable maturity to the remaining term of this Note. "Independent Investment Banker" means one of the Reference Treasury Dealers appointed by the Trustee after consultation with the Company.

        "Comparable Treasury Price" means, with respect to any Redemption Date, (i) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (ii) if the Trustee obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations. "Reference Treasury Dealer Quotations" means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 3:30 p.m. New York time on the third business day preceding such Redemption Date.

        Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date interest will cease to accrue on this Note or portions thereof called for redemption.

        In the event of redemption of this Note in part only, a new Note for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

If no Optional Repayment Date is set forth on the first page hereof, this Note will not be repayable at the option of the Holder prior to Stated Maturity. On any Optional Repayment Date, this Note will be repayable in whole or in part in increments of $1,000 at the option of the Holder hereof at a price equal to 100% of the principal amount to be repaid, together with interest thereon payable to the Optional Repayment Date, on notice in the form entitled "Option to Elect Repayment" below, duly completed, given together with this Note by such Holder to the Company not more than 60 nor less than 30 days prior to the Optional Repayment Date. In the event of repayment of this Note in part only, a new Note for the portion hereof not repaid will be issued in the name of the Holder hereof upon the surrender hereof. Exercise of such repayment option by the Holder shall be irrevocable.

        If an Event of Default with respect to the Notes shall occur and be continuing, the principal of all of the Notes may be declared due and payable in the manner and with the effect provided in the Indenture.
