QUESTAR REGULATED SERVICES COMPANY,
                     QUESTAR GAS COMPANY, AND
                     QUESTAR PIPELINE COMPANY

                 ANNUAL MANAGEMENT INCENTIVE PLAN
         (As Amended and Restated Effective May 18, 1999)

          Paragraph 1.  Name.  The name of this Plan is the Annual
Management Incentive Plan (the Plan) for Questar Regulated Services
Company, Questar Gas Company, and Questar Pipeline Company
(collectively referred to as Regulated Services).

          Paragraph 2.  Purpose.  The purpose of the Plan is to
provide an incentive to officers and key employees of Regulated
Services for the accomplishment of major organizational and individual
objectives designed to further the efficiency, profitability, and
growth of Regulated Services.

          Paragraph 3.  Administration.  The Management Performance
Committee (Committee) of the Board of Directors of Questar Corporation
(Questar) shall have full power and authority to interpret and
administer the Plan.  Such Committee shall consist of no less than
three disinterested members of the Board of Directors.
Recommendations made by the Committee shall be reviewed by the Boards
of Directors of participating employers.

          Paragraph 4.  Participation.  Within 60 days after the
beginning of each year, the Committee shall nominate Participants from
the officers and key employees for such year.  The Committee shall
also establish a target bonus for the year for each Participant
expressed as a percentage of base salary or specified portion of base
salary.  Participants shall be notified of their selection and their
target bonus as soon as practicable.

          Paragraph 5.  Determination of Performance Objectives.
Within 60 days after the beginning of each year, the Committee shall
establish target, minimum, and maximum performance objectives for
Regulated Services and for its affiliates and shall determine the
manner in which the target bonus is allocated among the performance
objectives.  The Committee shall also recommend a dollar maximum for
payments to Participants for any Plan year.  The Board of Directors
shall take action concerning the recommended dollar maximum within 60
days after the beginning of the Plan year.  Participants shall be
notified of the performance objectives as soon as practicable once
such objectives have been established.

          Paragraph 6.  Determination and Distribution of Awards.  As
soon as practicable, but in no event more than 90 days after the close
of each year during which the Plan is in effect, the Committee shall
compute incentive awards for eligible participants in such amounts as
the members deem fair and equitable, giving consideration to the
degree to which the Participant's performance has contributed to the
performance of Regulated Services and its affiliated companies and
using the target bonuses and performance objectives previously
specified.  Aggregate awards calculated under the Plan shall not
exceed the maximum limits approved by the Board of Directors for the year
involved. To be eligible to receive a payment, the Participant must be
actively employed by Regulated Services or an affiliate as of the date
of distribution except as provided in Paragraph 8.

          Amounts shall be paid (less appropriate withholding taxes
and FICA deductions) according to the following schedule:

                        100%

          Paragraph 7.  Restricted Stock in Lieu of Cash.
Participants who have a target bonus of $10,000 or higher shall be
paid all deferred portions of such bonus with restricted shares of
Questar's common stock under Questar's Long-Term Stock Incentive Plan.
Such stock shall be granted to the participant when the initial award
is determined, but shall vest free of restrictions according to the
schedule specified above in Paragraph 6.

          Paragraph 8.  Termination of Employment.

          (a)  In the event a Participant ceases to be an employee
during a year by reason of death, disability or approved retirement,
an award, or a reduction in force, if any, determined in accordance
with Paragraph 6 for the year of such event, shall be reduced to
reflect partial participation by multiplying the award by a fraction
equal to the months of participation during the applicable year
through the date of termination rounded up to whole months divided by
12.

          For the purpose of this Plan, approved retirement shall mean
any termination  of service on or after age 60, or, with approval of
the Board of Directors, early retirement under Questar's qualified
retirement plan.  For the purpose of this Plan, disability shall mean
any termination of service that results in payments under Questar's
long-term disability plan. A reduction in force, for the purpose of
this Plan, shall mean any involuntary termination of employment due to
the Company's economic condition, sale of assets, shift in focus, or
other reasons independent of the Participant's performance.

     The entire amount of any award that is determined after the death
of a Participant shall be paid in accordance with the terms of
Paragraph 11.

          In the event of termination of employment due to disability,
approved retirement, or a reduction in force, a Participant shall be
paid the undistributed portion of any prior awards in his final
paycheck or in accordance with the terms of elections to voluntarily
defer receipt of awards earned prior to February 12, 1991, or deferred
under the terms of Questar's Deferred Compensation Plan.  In the event
of termination due to disability, approved retirement, or a reduction
in force, any shares of common stock previously credited to a
Participant shall be distributed free of restrictions during the last
month of employment.  The current market value (defined as the closing
price for the stock on the New York Stock Exchange on the date in
question) of such shares shall be included in the Participant's final
paycheck.  Such Participant shall be paid the full amount of any award
(adjusted for partial participation) declared subsequent to the date
of such termination within 30 days of the date of declaration.  Any
partial payments shall be made in cash.

          (b)  In the event a Participant ceases to be an employee
during a year by reason of a change in control, he shall be entitled
to receive all amounts deferred by him prior to February 12, 1991, and
all undistributed portions for prior Plan years.  He shall also be
entitled to an award for the year of such event as if he had been an
employee throughout such year.  The entire amount of any award for
such year shall be paid in a lump sum within 60 days after the end of
the year in question.  Such amounts shall be paid in cash.

          For the purpose of this Plan, a "change in control" shall be
deemed to have occurred if (i) any Acquiring Person (as that term is
used in the Rights Agreement dated February 13, 1996, between Questar
and ChaseMellon Shareholder Services, L.L.C. ("Rights Agreement")) is
or becomes the beneficial owner (as such term is used in Rule 13d-3
under the Securities Exchange Act of 1934) of securities of Questar
representing 25 percent or more of the combined voting power of
Questar, or (ii) the following individuals cease for any reason to
constitute a majority of the number of directors then serving as
directors of Questar:  individuals who, as of May 19, 1998, constitute
Questar's Board of Directors (Board) and any new director (other than
a director whose initial assumption of office is in connection with an
actual or threatened election contest, including but not limited to a
consent solicitation, relating to the election of directors of
Questar) whose appointment of election by the Board or nomination for
election by Questar's stockholders was approved or recommended by a
vote of at least two-thirds of the directors when still in office who
either were directors on May 19, 1998, or who appointment, election or
nomination for election was previously so approved or recommended; or
(iii Questar stockholders approve a merger or consolidation of Questar
or any direct of indirect subsidiary of Questar with any other
corporation, other than a merger of consolidation that would result in
the voting securities of Questar outstanding immediately prior to such
merger or consolidation continuing to represent (either by remaining
outstanding or by being converted into voting securities of the
surviving entity or any parent thereof) at least 60 percent of the
combined voting power of the securities of Questar or such surviving
entity or its parent outstanding immediately after such merger or
consolidation, or a merger or consolidation effected to implement a
recapitalization of Questar (or similar transaction) in which no
person is or becomes the beneficial owner, directly or indirectly, of
securities of Questar representing 25 percent or more of the combined
voting power of Questar's then outstanding securities; or (iv)
Questar's stockholders approve a plan of complete liquidation or
dissolution of the Company or there is consummated an agreement for
the sale or disposition by Questar of all or substantially all of
Questar's assets, other than a sale of disposition by Questar of all
or substantially all of the Company's assets to an entity, at least 60
percent of the combined voting power of the voting securities of which
are owned by stockholders of Questar in substantially the same
proportion as their ownership of Questar immediately prior to such
sale.  A change in control, however, shall not be considered to have
occurred until all conditions precedent to the transaction, including
but not limited to, all required regulatory approvals have been
obtained.

          Paragraph 9.  Interest on Previously Deferred Amounts.
Amounts voluntarily deferred prior to February 12, 1991, shall be
credited with interest from the date the payment was first available
in cash to the date of actual payment.  Such interest shall be
calculated at a monthly rate using the typical rates paid by major
banks on new issues of negotiable Certificates of Deposit in the
amounts of $1,000,000 or more for one year as quoted in The Wall
Street Journal on the first day of the relevant calendar month or the
next preceding business day if the first day of the month is a
non-business day.

          Paragraph 10.  Coordination with Deferred Compensation Plan.
Some Participants are entitled to defer the receipt of their cash
bonuses under the terms of Questar's Deferred Compensation Plan, which
became effective November 1, 1993.  Any cash bonuses deferred pursuant
to the Deferred Compensation Plan shall be accounted for and
distributed according to the terms of such plan and the choices made
by the Participant.

          Paragraph 11.  Death and Beneficiary Designation.  In the
event of the death of a Participant, any undistributed portions of
prior awards shall become payable.  Amounts previously deferred by the
Participant, together with credited interest to the date of death,
shall also become payable.  Each Participant shall designate a
beneficiary to receive any amounts that become payable after death
under this Paragraph or Paragraph 8.  In the event that no valid
beneficiary designation exists at death, all amounts due shall be paid
as a lump sum to the estate of the Participant.  Any shares of
restricted stock previously credited to the Participant shall be
distributed to the Participant's beneficiary or, in the absence of a
valid beneficiary designation, to the Participant's estate, at the
same time any cash is paid.

          Paragraph 12.  Amendment of Plan.  The Boards of Directors
for the participating employers, at any time, may amend, modify,
suspend, or terminate the Plan, but such action shall not affect the
awards and the payment of such awards for any prior years.  The Boards
of Directors for the participating employers cannot terminate the Plan
in any year in which a change of control has occurred without the
written consent of the Participants.  The Plan shall be deemed
suspended for any year for which the Board of Directors has not fixed
a maximum dollar amount available for award.

          Paragraph 13.  Nonassignability.  No right or interest of
any Participant under this Plan shall be assignable or transferable in
whole or in part, either directly or by operation of law or otherwise,
including, but not by way of limitation, execution, levy, garnishment,
attachment, pledge, bankruptcy, or in any other manner, and no right
or interest of any Participant under the Plan shall be liable for, or
subject to, any obligation or liability of such Participant.  Any
assignment, transfer, or other act in violation of this provision
shall be void.

          Paragraph 14.  Effective Date of the Plan.  The Plan shall
be effective with respect to the fiscal year beginning January 1,
1997, and shall remain in effect until it is suspended or terminated
as provided by Paragraph 12.  This Plan replaces the individual plans
previously adopted by Questar Gas and Questar Pipeline that became
effective January 1, 1984.  Plan participants who previously received
awards under predecessor plans or any other Annual Management
Incentive Plan adopted by an affiliate shall be treated as ongoing
participants for purposes of the distribution schedule in Paragraph 6.
