|The interim financial statements reflect all adjustments which are, in the opinion of management, necessary for a fair presentation of the results of operations for the interim periods presented. All such adjustments are of a normal recurring nature.  While the transportation and storage operations are influenced by weather conditions, the straight fixed-variable rate design, which allows for recovery of substantially all fixed costs in the demand or reservation charge, reduces the earnings impact of weather conditions.

|On October 20, 2002 Questar Pipeline sold Questar TransColorado, Inc., the holding company holding Questar's interest in the TransColorado pipeline to Kinder Morgan, Inc. and affiliates for $105.5 million.  The sale was effective October 1, 2002, subject to normal review by the Federal Trade Commission (FTC) under the Hart-Scott-Rodino Antitrust legislation.  Affiliates of Questar and Kinder Morgan were co-owners of the TransColorado Pipeline that extended from northwestern Colorado to northern New Mexico.  Questar Pipeline exercised a contractual right (put) in 2001 to sell its 50% interest to an affiliate of Kinder Morgan.  Following lengthy legal proceedings, a Colorado court issued a judgment upholding Questar Pipeline's right to exercise the put.  The proceeds from the sale are being held in escrow pending the outcome of the FTC review and when released will be used to retire debt at Questar Pipeline.

|On October 30, 2002, Questar Overthrust Pipeline Co., an affiliate of Questar Pipeline, acquired the final 10% partnership interest in the Overthrust Pipeline Company from El Paso affiliate, CIG Overthrust Inc.  The $1.8 million transaction gives Questar, through two affiliates, 100% interest in the 88-mile line, which runs from Evanston, Wyoming to Rock Springs, Wyoming.  The Overthrust Pipeline was initially constructed as the westernmost leg of the 800-mile Trailblazer Pipeline that continues to Beatrice, Nebraska. In the first quarter of 2002, Questar Pipeline had acquired an additional 18% interest in the Overthrust pipeline from Natural Gas Pipeline, an affiliate of Kinder Morgan.

|As of September 30, 2002, Questar Pipeline, directly or indirectly through subsidiaries, had interests in partnerships accounted for on an equity basis. As previously discussed in Notes 2 and 3, beginning with the fourth quarter of 2002 those relationships will cease.  Historically, Questar TransColorado, Inc. (a subsidiary of Questar Pipeline) owned 50% of TransColorado pipeline (a general partnership) and as of September 30, 2002, Questar Pipeline owned 90% of Overthrust Pipeline Company (a general partnership).  Questar Pipeline did not consolidate the financial results of Overthrust Pipeline because it did not have a controlling interest.  The partnership agreement required approval of each partner in any significant partnership decisions.  Transportation of natural gas was the primary business activity of these partnerships.  Summarized gross operating results of the partnerships are listed below.

|Operating and maintenance expenses were higher in the 2002 periods primarily because of legal fees, the start-up of operation of the eastern segment of the Southern Trails Pipeline and higher labor-related costs.  Operating expenses of the Southern Trails Pipeline were responsible for approximately a $2.3 million increase in the comparison of the year to date periods presented. Legal expenses were $1 million higher in the first nine months of 2002 when compared with the 2001 period primarily due to litigation surrounding the TransColorado pipeline.  The TransColorado litigation was resolved with the sale of Questar Pipeline's share of TransColorado in October of 2002.  Pension and medical expenses have increased approximately $.5 million in 2002.   The return earned on pension assets is lower in 2002 causing an increase in pension expenses. As a result of lower commodity prices, gas purchased and used in the QTS processing plant was approximately $.8 million less in the first nine months of 2002 compared with the 2001 period, partially offsetting the increases discussed.

|On October 20, 2002, the complex legal issues between the partners of TransColorado Gas Transmission Company were resolved with the sale of Questar TransColorado, Inc.'s 50% interest in the TransColorado Pipeline for $105.5 million. The parties arranged the sale after a Colorado judge declared that Questar TransColorado's right to put (sell) its 50% interest in the pipeline to an affiliate of Kinder Morgan was valid and enforceable. As a result of the sale, the Company reduced the carrying value of its investment in TransColorado by $3 million in the third quarter of 2002 to reflect the net realized value of the sale.

|The Company's share of the TransColorado partnership was a pretax profit of $4.8 million for the third quarter and $6.9 million for the first nine months of 2002. The pipeline has operated near capacity in the second and third quarters of 2002 as a result of the wide basis differentials between gas prices in the Rockies and the San Juan Basin. TransColorado reported a $1.5 million pretax loss for the year earlier nine-month period.

|Net cash provided from operating activities of $49.3 million in the nine months of 2002 was $2.5 million less than the amount reported for the same period of 2001 due to changes in operating assets and liabilities.  The decline resulted primarily from a timing difference caused by a reduction of accounts payable.

The downgrade will not materially affect Questar Pipeline's growth strategy.

|On July 1, 2002, Questar Corporation filed a shelf registration statement with the Securities and Exchange Commission to issue common equity or mandatory convertible securities if necessary to achieve debt-reduction goals.

In addition, forward-looking statements generally can be identified by the use of forward-looking terminology such as "may", "will", "could", "expect", "intend", "project", "estimate", "anticipate", "believe", "forecast", or "continue" or the negative thereof or variations thereon or similar terminology.  Although these statements are made in good faith and are reasonable representations of the Company's expected performance at the time, actual results may vary from management's stated expectations and projections due to a variety of factors.

|As previously mentioned under Item 1., as of September 30, 2002, Questar Pipeline's subsidiary Questar TransColorado, Inc. was a 50 percent partner in TransColorado.  This partnership was originally formed in 1990 to build and operate the TransColorado pipeline that commenced operations March 31, 1999.  (The partnership agreement was subsequently amended in 1995, 1997 and 1998.)  This pipeline extends from a point on Questar Pipeline's system 25 miles east of Rangely in northwestern Colorado and extends 292 miles to the Blanco hub in northwestern New Mexico. The partnership agreement is filed as Exhibit 10.3 to Questar Pipeline's 2001 Annual Report on Form 10-K.



|As of September 30, 2002, Questar Pipeline also had a 90 percent interest in and is the operating partner of Overthrust Pipeline Company ("Overthrust"), a general partnership that was organized in 1979 to construct, own and operate the Overthrust segment of Trailblazer Pipeline System ("Trailblazer").  The 88-mile Overthrust segment is the western-most of Trailblazer's three segments; Trailblazer itself is an 800-mile pipeline that transports gas from producing areas in the Rocky Mountains to the Midwest.  The remaining 10 percent was owned by an affiliate of El Paso Corporation and was purchased by Questar in October 2002. (The partnership agreement is filed as Exhibit 10.1 to Questar Pipeline's 2001 Annual Report on Form 10-K.)

|Gains and losses on the reacquisition of debt are deferred and amortized as debt expense over the would-be remaining life of the retired debt or the life of the replacement debt in order to match regulatory treatment.  The cost of the early retirement windows offered to employees is capitalized and amortized over a five-year period in accordance with regulatory treatment.   The Company records cumulative increases in deferred taxes as income taxes recoverable from customers.  The Company has adopted procedures with the FERC to include under- and over-provided deferred taxes in customer rates on a systematic basis.  Questar Pipeline uses the deferral method to account for investment tax credits as required by the FERC.  Regulation allows the Company to recover costs, but does not provide for a return on these assets.  A list of regulatory assets at December 31 follows:

|INDEMNIFICATION AND LIABILITY INSURANCE
|---------------------------------------



|SECTION 41.  (a)  Voluntary Indemnification.  Unless otherwise provided in the Articles of Incorporation, the Corporation shall indemnify any individual made a party to a proceeding because he is or was a director of the Corporation, against liability incurred in the proceeding, but only if the Corporation has authorized the payment in accordance with the applicable statutory provisions [Sections 16-10a-902 and 16-10a-904 of Utah's Revised Business Corporation Act] and a determination has been made in accordance with the procedures set forth in such provision that the director conducted himself in good faith; that he reasonably believed that his conduct, if in his official capacity with the Corporation, was in its best interests and that his conduct, in all other cases, was at least not opposed to the Corporation's best interests; and that he had no reasonable cause to believe his conduct was unlawful in the case of any criminal proceeding.
|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(b)  The Corporation may not voluntarily indemnify a director in connection with a proceeding by or in the right of the Corporation in which the director was adjudged liable to the Corporation or in connection with any other proceeding charging improper personal benefit to him, whether or not involving action in his official capacity, in which he was adjudged liable on the basis that personal benefit was improperly received by him.
|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(c)  Indemnification permitted under Paragraph (a) in connection with a proceeding by or in the right of the Corporation is limited to reasonable expenses incurred in connection with the proceeding.
|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(d)  If a determination is made, using the procedures set forth in the applicable statutory provision, that the director has satisfied the requirements listed herein and if an authorization of payment is made, using the procedures and standards set forth in the applicable statutory provision, then, unless otherwise provided in the Corporation's Articles of Incorporation, the Corporation shall pay for or reimburse the reasonable expenses incurred by a director who is a party to a proceeding in advance of the final disposition of the proceeding if the director furnishes the Corporation a written affirmation of his good faith belief that he has satisfied the standard of conduct described in this Section, furnishes the Corporation a written undertaking, executed personally or on his behalf, to repay the advance if it is ultimately determined that he did not meet the standard of conduct (which undertaking must be an unlimited general obligation of the director, but need not be secured and may be accepted without reference to financial ability to make repayment); and if a determination is made that the facts then known of those making the determination would not preclude indemnification under this Section.
|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(e)  Mandatory Indemnification.  Unless otherwise provided in the Corporation's Articles of Incorporation, the Corporation shall indemnify a director or officer of the Corporation who was wholly successful, on the merits or otherwise, in the defense of any proceeding to which he was a party because he is or was a director or officer of the Corporation against reasonable expenses incurred by him in connection with the proceeding.
|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(f)  Court-Ordered Indemnification.  Unless otherwise provided in the Corporation's Articles of Incorporation, a director or officer of the Corporation who is or was a party to a proceeding may apply for indemnification to the court conducting the proceeding or to another court of competent jurisdiction.  The court may order indemnification if it determines that the director or officer is entitled to mandatory indemnification as provided in this Section and applicable law, in which case the court shall also order the Corporation to pay the reasonable expenses incurred by the director or officer to obtain court-ordered indemnification.  The court may also order indemnification if it determines that the director or officer is fairly and reasonably entitled to indemnification in view of all the relevant circumstances, whether or not the director or officer met the applicable standard of conduct set forth in this Section and applicable law.  Any indemnification with respect to any proceeding in which liability has been adjudged in the circumstances described in Paragraph (b) above is limited to reasonable expenses.
|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(g)  Indemnification of Others.  Unless otherwise provided in the Corporation's Articles of Incorporation, an officer, employee, or agent of the Corporation shall have the same indemnification rights provided to a director by this Section.   The Board of Directors may also indemnify and advance expenses to any officer, employee, or agent of the Corporation, to any extent consistent with public policy as determined by the general or specific purpose of the Board of Directors.
|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(h)  Insurance.  The Corporation may purchase and maintain liability insurance on behalf of a person who is or was a director, officer, employee, fiduciary, or agent or the Corporation, or who, while serving as a director, officer, employee, fiduciary, or agent of the Corporation, is or was serving at the request of the Corporation as a director, officer, partner, trustee, employee, fiduciary or agent of another foreign or domestic corporation, other person, of an employee benefit plan, or incurred by him in that capacity or arising from his status as a director, officer, employee, fiduciary, or agent, whether or not the Corporation has the power to indemnify him against the same liability under applicable law.

|LIMITATION ON LIABILITY
|-----------------------



|SECTION 41.  No director of the Corporation shall be personally liable to the Corporation or its stockholders for monetary damages for any action taken or any failure to take any action, as a director, except liability for (a) the amount of a financial benefit received by a director to which he is not entitled; (b) an intentional infliction of harm on the Corporation or the shareholders; (c) any action that would result in liability of the director under the applicable statutory provision concerning unlawful distributions [Section 16-10-842 of Utah's Revised Business Corporation Act]; or (d) an intentional violation of criminal law.  This provision shall not limit the liability of a director for any act or omission occurring prior to August 11, 1992.  Any repeal or modification of this provision by the stockholders shall be prospective only and shall not adversely affect any limitation on the personal liability of a director of the Corporation for acts or omissions occurring prior to the effective date of such repeal or modification.
