QUESTAR CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
June 30, 1998
(Unaudited)

Note 1 - Basis of Presentation

The interim financial statements furnished reflect all adjustments
which are, in the opinion of management, necessary for a fair
presentation of the results for the interim periods presented.  All
such adjustments are of a normal recurring nature.  Due to the
seasonal nature of the business, the results of operations for the
three- and six-month periods ended June 30, 1998 are not necessarily
indicative of the results that may be expected for the year ending
December 31, 1998.  For further information refer to the consolidated
financial statements and footnotes thereto included in the Company's
annual report on Form 10-K for the year ended December 31, 1997.


Note 2 - Planned Purchases of Gas and Oil Company and a Pipeline

A Questar subsidiary announced its intention, July 27, 1998,  to
acquire 100 percent of the common stock of HSRTW, Inc., a wholly
owned subsidiary of HS Resources, Inc. for $157.5 million, effective
September 1, 1998.  In the cash transaction, Universal Resources will
obtain an estimated 150 billion cubic feet equivalent of proved oil
and gas reserves primarily in Oklahoma, as well as in Texas, Arkansas
and Louisiana. The purchase price includes $155 million for gas and
oil reserves and other assets and $2.5 million for working capital.
Approximately 80 percent of the reserves are natural gas. The Company
plans to finance the purchase through short-term borrowings and an
expansion of its existing production-based credit facility.

On June 25, 1998 in an unrelated transaction another Questar
subsidiary announced its intention to acquire 700 miles of oil
pipeline from ARCO Pipe line Company. The purchase price of the line
is $40 million with financial closing expected on or about September
30, 1998.  The pipeline extends from northwestern New Mexico to Long
Beach, California.  Questar Pipeline will operate the pipeline once
it is modified to carry natural gas.  Reconditioning the pipe and
adding compression are scheduled to begin as soon as possible and
will continue for 18-24 months for an estimated total cost up to $60
million.  The project will be financed through short-term borrowings
until long-term debt can be issued.


Note 3 - Common Stock Split

In June 1998, Questar's common stock was split two shares for each
share outstanding.  Common stock disclosures, such as, earnings per
share, dividends per share and number of shares outstanding in the
prior period financial statements have been restated to reflect the
split.


Note 4 - Comprehensive Income

The Company adopted Statement of Financial Accounting Standards
(SFAS) No. 130 "Reporting Comprehensive Income" beginning January 1,
1998.  SFAS No. 130 establishes new rules for reporting comprehensive
income and its components.   However, the adoption of this statement
had no impact on Questar's net income and its shareholders' equity.
SFAS No. 130 requires unrealized gains or losses on
available-for-sale securities and foreign currency translation
adjustments to be included in other comprehensive income. Formerly,
these transactions were reported separately in shareholders' equity.
Prior year amounts have been reclassified to conform to the
requirements of SFAS No. 130.

</TABLE>

Revenues from Market Resource operations were higher in the second
quarter of 1998 when compared with the second quarter of 1997 due
primarily to increased energy-marketing activities, particularly gas,
and higher gas production and prices.  Revenues were $68,335,000 or
23% lower in the first half of 1998 when compared to the prior year
period primarily the result of a 28% decrease in gas-marketing
volumes.  Energy marketing activities reported $368,000 of net income
in the first half of 1998 compared with a $945,000 loss in the first
half of 1997.

Gas production increased 2% in the first half of 1998 when compared
with the first half of 1997 and the average price increased 10%.  The
increase in production resulted from gas wells drilled in the Rocky
Mountain region in 1997.

Oil and NGL revenues were $10,755,000 lower in the first half
comparison due to a 30% drop in prices and a 9% decline in
production. The production decline was the result of the sale of
nonstrategic assets in 1997, normal production declines and a
temporary shutdown of the Brady processing plant due to a
construction project.

Market Resources hedged approximately 55% of its gas production
through June of 1999 with a price of about $2.10 per Mcf, net back to
the well.  Roughly 26% of its oil production was hedged at
approximately $16.90 per bbl for the remainder of 1998.  These
amounts include production volumes to be acquired from HS Resources.

Revenues for Questar Gas Management (QGM) decreased $8,335,000 or 39%
in the first half of 1998 compared with the same period in 1997 due
to a gathering contract revision and the sale of two processing
plants in 1997. Net income reported by QGM was $1,434,000 below last
year's income as a result of these factors and lower earnings from a
gas and NGL processing plant.

Revenues, less natural gas purchases, were $1,232,000 lower in the
second quarter of 1998 and $5,643,000 lower in the 6-month period
ended June 30, 1998 when compared with the same periods in 1997
because of several rate changes affecting the first half of 1998.  A
rate surcharge, associated with construction of a distribution
pipeline into southern Utah and in effect for the past 10 years, was
discontinued in September 1997.  Some general-service customers, who
met higher load factor standards, shifted to firm commercial rates,
which have a lower margin.  Retail usage of gas per customer fell
during the first half of 1998 after reaching an unusually high mark
in the first half of 1997. This is in large part attributable to
reaction to rising gas costs included in rates during the latter part
of 1997 and first part of 1998.

Partially offsetting the rate changes and lower usage per customer
has been the effect of a strong growth rate in the number of
customers served by Questar Gas.  The number of customers served grew
by 3.5% from a year ago to 643,696 at June 30, 1998.

Temperatures, as measured in degree days, were colder than normal in
the second quarter of 1998. However, the impact was slight because
temperatures are relatively mild during the second quarter in
comparison with the winter heating season that extends from November
through March.   Also, Questar Gas' rates include a
weather-normalization adjustment that reduces the revenue impact of
weather fluctuations.  Virtually all of Questar Gas' residential and
commercial volumes were covered under the weather-normalization
adjustment in the first half of both 1998 and 1997.

In March 1998, the Public Service Commission of Wyoming approved
Questar Gas' gas-merchant unbundling proposal that was filed in
Wyoming in 1997.  Under this plan, a transportation service option
was extended to residential and commercial customers as well as
industrial customers.  Customers choosing transportation service are
allowed to secure gas supplies directly from producers and marketers
and pay Questar Gas a fee for transportation services.  Questar Gas
continues to offer a traditional bundled sales service as well.  The
unbundling proposal called for an open enrollment period to be held
from March 1 through April 30.  However, no suppliers signed up to
provide gas to Wyoming customers.  Another open enrollment will be
held next year.  Questar expects that the option of unbundled service
in Wyoming will not have a material effect on earnings.

Volumes delivered to industrial customers increased 12% in the first
half of 1998 when compared with the same period of 1997 due to
additions of  new customers as well as expanded operations with
several ongoing customers.  Margins from gas delivered to industrial
customers are substantially lower than from gas delivered to
residential and commercial customers.

Questar Gas, as a result of acquiring Questar Pipeline's gas purchase
contracts, is responsible for any judgment rendered against Questar
Pipeline in a lawsuit that was tried before a jury in 1994.  In a
ruling issued June 2, 1998, the trial judge set aside all aspects of
the jury's verdict except for $.5 million in favor of a producer
related to certain contractual, take-or-pay issues.  Other than on
these take-or-pay matters, a judgment was entered on all other issues
in favor of Questar Pipeline.  A notice of appeal has been filed by
the producer.

Revenues were higher in the 3-, 6- and 12-month periods of 1998 due
primarily to increased firm-transportation and firm-storage
reservation charges.  Questar Pipeline expanded working gas capacity
by 5 Bcf at Clay Basin for a capital investment of $4 million.  The
expansion is expected to add about $3 million in annual storage
revenues.  Service began in the second quarter of 1998 and all new
capacity was committed to long-term contracts.

Income from unconsolidated affiliates in the 1998 periods include the
Company's share of earnings reported by TransColorado Gas
Transmission Co.  The noncash earnings reflect capitalization of
interest and equity costs (AFUDC) associated with the construction of
the TransColorado pipeline amounting to $405,000 in the 3-month
period, $723,000 in the 6-month period and $5,179,000 in the 12-month
period ended June 30, 1998.

Consolidated Results of Operations

Consolidated revenues were 18% higher in the second quarter ended
June 30, 1998 when compared with the second quarter of 1997 due to
increased revenues from energy-marketing and gas-distribution
activities.  Consolidated revenues were lower in the 6- and 12-month
periods ended June 30, 1998 when compared with the same periods of
1997 due primarily to decreased energy-marketing activities, oil
prices and oil production, which more than offset higher
gas-distribution revenues, gas production and gas prices during these
same reporting periods.

Natural gas and other product purchases were 60% higher in the second
quarter ended June 30, 1998 when compared with the second quarter of
1997 due to the increased cost, primarily of gas, purchased for
energy-marketing activities and higher gas costs recovered in
distribution rates.  Natural gas and other product purchases were
lower in the 6- and 12-month periods of 1998 due primarily to a
decrease in the quantity of gas purchased for energy-marketing
activities.

Increased labor-related costs for data processing caused a 4%
increase in operating and maintenance (O & M) expenses in the second
quarter of 1998 when compared with the same period in the prior year.
Cost-containment efforts, capitalizing labor costs associated with
construction projects and lower bad debt expenses in 1998 resulted in
lower O & M expenses in the 6- and 12-month periods of 1998.  The
Company continues efforts to resolve Year 2000 issues and expects
that the expense of becoming Year 2000 compliant will not be
material.  Depreciation expenses were lower in the 3- and 6- month
periods of 1998 when compared to the 1997 periods because of a lower
full-cost amortization rate and an adjustment associated with
transmission properties.  The full-cost amortization rate for
combined US and Canadian operations was $.83 per equivalent Mcf for
the first half of 1998 down from $.85 for the 1997 period.
Depreciation Other taxes, primarily production and property taxes,
were lower in the 6- and 12-month periods of 1998 because of lower
oil prices and production, and refunds and lower assessments of state
property taxes.

Eligible employees in the Company's Regulated Services group and in
Questar Energy Services, Inc., were offered an early retirement
program that was effective July 31, 1998.  Enhanced benefits will be
paid to 178 employees taking advantage of the offer.   The regulated
services work force was reduced by more than 10% or 177 employees,
which will decrease future operating expenses.  The Regulated
Services group will defer and amortize the costs associated with the
early retirement program over a five-year period in accordance with
past regulatory treatment.  The deferred annual charge is expected to
be more than offset by lower labor-related costs.

Interest and other income was higher in the 3- and 6-month periods of
1998 due primarily to a $5,727,000 pretax gain on an exchange of an
interest in Nextlink and $829,000 of interest earned on a
fiber-optics communications project with Nextlink.  In addition to
the items mentioned, higher pretax gains from selling Nextel shares
and increased earnings from unconsolidated affiliates resulted in an
increase in interest and other income reported in the 12-month period
ended June 30, 1998.

The effective income tax rate for the first six months was 32.1% in
1998 and 32.2% in 1997.  The Company recognized $4,246,000 of
production-related tax credits in the 1998 period and $4,917,000 in
the 1997 period.

Liquidity and Capital Resources

Operating Activities

Net cash provided from operating activities of $174,811,000 for the
first half of 1998 was $37,963,000 higher than was generated in the
same period of 1997.  The increase in cash flow resulted primarily
from collection of gas costs incurred by natural gas distribution
operations, which were under-collected in the first half of 1997.

Investing Activities

Capital expenditures were $93,521,000 for the first half of 1998, up
$27,513,000 from the $66,008,000 reported for the same period a year
ago.  A comparison of capital expenditures by lines of business for
the first six months of 1998 and 1997 plus an estimate for calendar
year 1998 are below.  The 1998 forecast includes announced purchases
of a gas and oil company for $157,500,000 and a pipeline for
$40,000,000.  Both transactions are expected to be effective in the
third quarter of 1998.

Financing Activities

In the first half of 1998 net cash flow provided from operating
activities was used to reduce short-term debt by $53,600,000 and
long-term debt by $38,638,000 and to fund capital expenditures.  The
Company intends to finance forecasted 1998 capital expenditures
through net cash provided from operating activities, bank borrowings
and issuing long-term debt.

Short-term borrowings, represented by commercial paper, amounted to
$77,600,000 at June 30, 1998 and $44,100,000 at June 30, 1997.  The
Company has short-term bank lines of credit, which serve as backup to
borrowings made under the commercial paper program.  The Company's
lines of credit borrowing capacity is $100 million April 1 through
September 30 to match seasonal-borrowing patterns. However, the
capacity is being expanded to $300 million for interim financing to
accommodate capital spending until long-term financing can be
arranged.

                            ARTICLE VII

          In furtherance but not in limitation of the powers conferred 
by the statutes of the State of Utah, the Board of Directors without 
the  authority, consent, vote or other action of the stockholders, or 
any of them, is expressly authorized:

          From time to time, as and when, and upon such terms and 
conditions as it may determine, to issue any part of the authorized 
capital stock of the Corporation, without being required to offer such 
stock on a pro rata basis to the stockholders of the Corporation.  

          To purchase, or otherwise acquire for the Corporation, any 
property, rights or privileges which the Corporation is authorized to 
acquire at such price or consideration and generally upon such terms 
and conditions as it deems fit.  

          In its discretion to pay for any property or rights acquired 
by the Corporation, either wholly or partly in money, stock, bonds, 
debentures, or other securities of the Corporation.  

          From time to time to fix and vary the amount of the working 
capital, and to direct and determine the use and disposition of any 
surplus or net profits, over and above the capital stock paid in; and 
in its discretion to use and apply any such surplus or accumulated 
profits in acquiring the bonds or other obligations or shares of the 
capital stock of this Corporation to such an extent and in such manner 
and upon such terms as the Board of Directors shall deem expedient, 
but no funds or property of the Corporation shall be used for the 
purchase of its own shares of capital stock when such use would cause 
any impairment of the capital of the Corporation, and shares of its 
capital stock, when acquired by the Corporation may, from time to 
time, successively be resold and repurchased.  

          To issue and sell, pledge or otherwise dispose of bonds, 
debentures or other obligations of the Corporation from time to time, 
without limitation as to amount, for any of the objects or purposes of 
the Corporation, and, if desired, to secure the same of any thereof by 
mortgage, pledge, deed of trust or otherwise, upon all or any part of 
the property of every kind of the Corporation, and to cause the 
Corporation to guarantee bonds, debentures, dividends or other 
obligations of other corporations.  

          At any time, or from time to time, to sell, assign, 
transfer, convey, lease or otherwise dispose of the whole or any part 
of the property and assets of every kind and nature of the Corporation 
upon such terms and conditions as the Board of Directors may deem 
expedient for the best interests of the Corporation.  

          To cause the Corporation to be licensed or recognized in any 
state, county, city or other municipality of the United States, the 
territories thereof, the District of Columbia, colonial possessions or 
territorial acquisitions, and in any foreign country, and in any town, 
city or municipality thereof, to conduct its business and have one or 
more offices therein.  

          To make, alter, amend or rescind the Bylaws of the 
Corporation.  

          To authorize and cause to be executed, mortgages and liens 
upon the real and personal property of the Corporation.  

          From time to time to determine whether and to what extent, 
and at what time and place and under what conditions and regulations, 
the accounts and books of this Corporation (other than the stock 
ledger) or any of them, shall be open to the inspection of the 
stockholders, and no stockholder shall have any right to inspect any 
account or book or document of this Corporation, except as permitted 
by statute of the State of Utah or authorized by the Board of 
Directors.  

          The Corporation may, in its Bylaws, confer powers additional 
to the foregoing upon the Directors in addition to the powers and 
authority expressly conferred upon them by statute.

                            ARTICLE XI

        1.  Effective as of the initial annual meeting of 
stockholders, there shall be thirteen (13) directors of the 
Corporation, notwithstanding any other provision of these Articles of 
Incorporation or of the Bylaws.  

        2.  The directors, except those hereinbefore named as initial 
directors and those chosen to fill a vacancy for an unexpired term, 
must be elected by the stockholders at the regular annual stockholders 
meeting, or, if not held, at any special meeting of the stockholders 
called for that purpose.  As to the directors elected at the initial 
annual meeting of stockholders, the first class of directors shall 
hold office for an initial term of one (1) year, the second class of 
directors shall hold office for an initial term of two (2) years, and

provision of these Articles of Incorporation or of the Bylaws, any 
director or directors, including the entire Board of Directors, may be 
removed at any time, but only with cause and by the affirmative vote 
of at least two-thirds of the issued and outstanding stock of the 
Corporation that is entitled to vote for the election of directors, 
and no qualification for the office of director that may be provided

any successor appointed by the remaining directors to fill the 
unexpired portion of the term of such director.  

        No director of the Corporation shall be personally liable to 
the Corporation or its stockholders for monetary damages for any 
breach of fiduciary duty by such director as a directory, except for 
liability (i) for any breach of the director's duty of loyalty to the 
Corporation or its stockholders; (ii) for acts or omissions not in 
good faith or that involve intentional misconduct or a knowing 
violation of law; (iii) for any transaction from which the director 
derived an improper personal benefit; or (iv) for any action that 
would result in statutory liability of the director under Section 
16-10-44 of the Utah Code Annotated.  Any repeal or modification of 
this paragraph 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.

                            ARTICLE XII

        The Corporation reserves the right to amend, alter, change or 
repeal any provisions contained in the Articles of Incorporation in 
the manner now or hereafter prescribed by statute, and all rights 
conferred upon stockholders herein are granted subject to this 
reservation.  Nevertheless, and in addition to any other provision of 
these Articles of Incorporation, the Bylaws, or statutes, the 
affirmative vote of eighty percent of the issued and outstanding 
capital stock of the Corporation that is entitled to vote for the 
election of directors shall be required for the deletion of language 
in or any amendment to Article XI, this Article XII, or Article XIV or 
for any amendment to these Articles of Incorporation or to the Bylaws 
(unless such amendment to the Bylaws is approved by the Directors in 
accordance with the Bylaws) that would restrict or limit the power or 
authority of the Board of Directors or any other officer or agent of 
the Corporation; that would vest any powers of the Corporation in any 
other officer or agent other than the Board of Directors or officers 
and agents appointed by or under the authority of the Board of 
Directors; that would require the approval of any stockholders in 
order for the Board of Directors or any officer or agent to take any 
action; or that would change the quorum requirement for any meeting of 
the Board of Directors, the vote by which it must act in connection 
with any matter, the manner of calling or conducting meetings of 
Directors, or the place of such meetings.  

                           ARTICLE XIII

        The private property of the stockholders shall not be liable 
for any obligations or debts of the Corporation.  

                            ARTICLE XIV

        1.  The affirmative vote of the holders of not less than 
eighty percent of the outstanding shares of capital stock of the 
Corporation entitled to vote shall be required for the approval or 
authorization of any "Business Combination" (as hereinafter defined) 
involving a "Related Person" (as hereinafter defined); provided, 
however, that the eighty percent voting requirement shall not be 
applicable if:

             (a)  The "Continuing Directors" (as hereinafter defined) 
of the Corporation by a two-thirds vote have expressly approved such 
Business Combination either in advance of or subsequent to such 
Related Person's having become a Related Person; or

             (b)  The following conditions are satisfied:

                 (i)  The aggregate amount of the cash and the "Fair 
Market Value" (as hereinafter defined) of the property, securities or 
"Other Consideration" (as hereinafter defined) to be received per 
share by all holders of capital stock of the Corporation in the

Business Combination, is not less than the "Highest Per Share Price" 
or the "Highest Equivalent Price" (as hereinafter defined) paid by the 
Related Person in acquiring any of its holdings of the Corporation's 
capital stock; and

                 (ii)  A proxy statement complying with the 
requirements of the Securities Exchange Act of 1934, as amended, 
whether or not the Corporation is then subject to such requirements 
shall have been mailed to all stockholders of the Corporation for the 
purpose of soliciting stockholder approval of the Business 
Combination.  The proxy statement shall contain at the front thereof, 
in a prominent place, the position of the Continuing Directors as to 
the advisability (or inadvisability) of the Business Combination and, 
if deemed advisable by a majority of the Continuing Directors, the 
opinion of an investment banking firm selected by the Continuing 
Directors as to the fairness of the terms of the Business Combination, 
from the point of view of the holders of the outstanding shares of 
capital stock of the Corporation other than any Related Person.  

        Such eighty percent vote shall be required notwithstanding the 
fact that no vote may be required or that a lesser percentage may be 
specified by law or in any agreement with any national securities 
exchange or otherwise.  

        2.  For purposes of this Article XIV:

             (a)  The term "Business Combination" shall mean (i) any 
merger, consolidation or share exchange of the Corporation or a 
subsidiary of the Corporation with or into a Related Person, in each 
case without regard to which entity is the surviving entity; (ii) any 
sale, lease, exchange, transfer or other disposition, including 
without limitation a mortgage or any other security device, of all or 
any "Substantial Part" (as hereinafter defined) of the assets of the 
Corporation (including without limitation any voting securities of a 
subsidiary of the Corporation) or a subsidiary of the Corporation to 
or with a Related Person (whether in one transaction or series of 
transactions); (iii) any sale, lease, exchange, transfer or other 
disposition, including without limitation a mortgage or any other 
security device, of all or any Substantial Part of the assets of a 
Related Person to the Corporation or a subsidiary of the Corporation; 
(iv) the issuance, transfer or delivery of any securities of the 
Corporation or a subsidiary of the Corporation by the Corporation or 
any of its subsidiaries to a Related Person (other than an issuance or 
transfer of securities which is effected on a pro rata basis to all 
stockholders of the Corporation); (v) any recapitalization or 
reclassification of securities (including any reverse stock split) 
that would have the effect of increasing the voting power of a Related 
Person; (vi) the issuance or transfer by a Related Person of any 
securities of such Related Person to the Corporation or a subsidiary 
of the Corporation (other than an issuance or transfer of securities 
which is effected on a pro rata basis to all stockholders of the 
Related Person); (vii) the adoption of any plan or proposal for the 
liquidation or dissolution of the Corporation proposed by or on behalf 
of a Related Person; or (viii) any agreement, plan, contract or other 
arrangement providing for any of the transactions described in this 
definition of Business Combination.  

             (b)  The term "Related Person" shall mean and include any 
individual, partnership, corporation or other person or entity which, 
as of the record date for the determination of stockholders entitled 
to notice of and to vote on any Business Combination, or immediately 
prior to the consummation of such transaction, together with its 
"Affiliates" and "Associates" (as defined in Rule 12b-2 of the General 
Rules and Regulations under the Securities Exchange Act of 1934 as in 
effect at the date of the adoption of this Article XIV by the 
stockholders of the Corporation (collectively, and as so in effect, 
the "Exchange Act")), are "Beneficial Owners" (as defined in Rule 
13d-3 of the Exchange Act) in the aggregate of 10% or more of the 
outstanding shares of any class of capital stock of the Corporation, 
and any Affiliate or Associate of any such individual, corporation, 
partnership or other person or entity.  Notwithstanding any provision 
of Rule 13d-3 to the contrary, an entity shall be deemed to be the 
Beneficial Owner of any share of capital stock of the Corporation that 
such entity has the right to acquire at any time pursuant to any 
agreement, or upon exercise of conversion rights, warrants or options, 
or otherwise.  

             (c)  The term "Substantial Part" shall mean more than 20% 
of the fair market value, as determined by two-thirds of the 
Continuing Directors, of the total consolidated assets of the 
Corporation and its subsidiaries taken as a whole as of the end of its 
most recent fiscal year ended prior to the time the determination is 
being made.  

             (d)  The term "Other Consideration" shall include, 
without limitation, Common Stock or other capital stock of the 
Corporation retained by stockholders of the Corporation other than 
Related Persons or parties to such Business Combination in the event 
of a Business Combination in which the Corporation is the surviving 
corporation.  

             (e)  The term "Continuing Director" shall mean a Director 
who is unaffiliated with any Related Person and either (i) was a 
member of the Board of Directors of the Corporation immediately prior 
to the time the Related Person involved in a Business Combination 
became a Related Person or (ii) was designated (before his or her 
initial election or appointment as Director) as a Continuing Director 
by a majority of the then Continuing Directors.  

             (f)  The terms "Highest Per Share Price" and "Highest 
Equivalent Price" as used in this Article XIV shall mean the 
following:  if there is only one class of capital stock of the 
Corporation issued and outstanding, the Highest Per Share Price shall 
mean the highest price that can be determined to have been paid at any 
time by the Related Person for any share or shares of that class of 
capital stock.  If there is more than one class of capital stock of 
the Corporation issued and outstanding, the Highest Equivalent Price 
shall mean with respect to each class and series of capital stock of 
the Corporation, the amount determined by a majority of the Continuing 
Directors, on whatever basis they believe is appropriate, to be the 
highest per share price equivalent of the Highest Per Share Price that 
can be determined to have been paid at any time by the Related Person 
for any share or shares of any class or series of capital stock of the 
Corporation.  In determining the Highest Per Share Price and Highest 
Equivalent Price, all purchases by the Related Person shall be taken 
into account regardless  of whether the shares were purchased before 
or after the Related Person became a Related Person.  Also, the 
Highest Per Share Price and the Highest Equivalent Price shall include 
any brokerage commissions, transfer taxes, soliciting dealers' fees 
and other expenses paid by the Related Person with respect to the 
shares of capital stock of the Corporation acquired by the Related 
Person.  In the case of any Business Combination with a Related 
Person, the Continuing Directors shall determine the Highest Per Share 
Price and the Highest Equivalent Price for each class and series of 
capital stock of the Corporation.  

             (g)  The term "Fair Market Value" shall mean (i) in the 
case of stock, the highest closing sale price during the 30-day period 
immediately preceding the date in question of a share of such stock on 
the Composite Tape for New York Stock Exchange-Listed Stocks, or, if 
such stock is not quoted on the Composite Tape, on the Exchange, on 
the principal United States securities exchange registered under the 
Securities Exchange Act of 1934 on which such stock is listed, or, if 
such stock is not listed on any such exchange, the highest closing bid 
quotation with respect to a share of such stock during the 30-day 
period preceding the date in question on the National Association of 
Securities Dealers, Inc., Automated Quotation System or any system 
then in use, or if no such quotations are available, the fair market 
value on the date in question of a share of such stock as determined 
by a two-thirds vote of the Continuing Directors in good faith; and 
(ii) in the case of property other than stock or cash, the fair market 
value of such property on the date in question as determined by a 
two-thirds vote of the Continuing Directors in good faith.  

        3.  The determinations of the Continuing Directors as to Fair 
Market Value, Highest Per Share Price, Highest Equivalent Price, and 
the existence of a Related Person or a Business Combination shall be 
conclusive and binding.  

        4.  Nothing contained in this Article XIV shall be construed 
to relieve any Related Person from any fiduciary obligation imposed by 
law.  

        5.  The fact that any Business Combination complies with the 
provisions of paragraph 1(b) of this Article XIV shall not be 
construed to impose any fiduciary duty, obligation or responsibility 
on the Board of Directors, or any member thereof, to approve such 
Business Combination or recommend its adoption or approval to the 
stockholders of the Corporation, nor shall such compliance limit, 
prohibit or otherwise restrict in any manner the Board of Directors, 
or any member thereof, with respect to evaluations of or actions and 
responses taken with respect to such Business Combination.  

        6.  Notwithstanding any other provisions of these Articles of 
Incorporation or the Bylaws of the Corporation, the affirmative vote 
of the holders of not less than eighty percent of the outstanding 
shares of capital stock shall be required to amend, alter, change or 
repeal, or adopt any provisions inconsistent with, this Article XIV.  

        The foregoing Restated Articles of Incorporation correctly set 
forth without change the corresponding provisions of the Restated 
Articles of Incorporation as previously amended and supersede the 
Restated Articles of Incorporation as amended.

     SECTION 7.  The Secretary shall give, but in case of his failure 
any other officer of the Corporation may give, written or printed 
notice to the stockholders stating the place, day and hour of each 
meeting of stockholders and, in case of a special meeting, the purpose 
or purposes for which the meeting is called.  Such notice shall be 
given not less than ten (10) nor more than fifty (50) days before the 
date of the meeting.  

     SECTION 8.  Notice may be given either personally or by mail, and 
if given by mail, such notice shall be deemed to be delivered when

such address as it appears on the stock transfer books of the 
Corporation, with postage prepaid thereon.  

     SECTION 9.  At each meeting of the stockholders, every 
stockholder having the right to vote shall be entitled to vote in 
person, or by proxy appointed by an instrument in writing, subscribed 
by such stockholder and bearing a date not more than eleven months

voted upon by stockholders.  A proposal shall be properly brought 
before the meeting if it is specified in the notice of such meeting 
(or any supplement to such notice) mailed by the Corporation to the 
stockholders, or if it is otherwise properly brought before the 
meeting by or at the direction of the Corporation's Board of 
Directors, or if such proposal is otherwise properly brought before 
such meeting by a stockholder entitled to vote at such meeting who has

annual meeting may refuse to allow any business to be brought before 
the meeting if the stockholder seeking to bring the business has not 
complied with the procedures specified in this section of the 
Corporation's Bylaws.

     SECTION 13.  At any meeting of stockholders at which directors 
are to be elected, nominations of persons for election to the 
Corporation's Board of Directors may be made by or at the direction of 
the Board of Directors or by any stockholder entitled to vote for the 
election of directors at such meeting.  Any stockholder proposing to 
make such nominations, if other than at the direction of the Board of 
Directors, may nominate one or more persons for election as directors 
only if written notice of such stockholder's intent to make such 
nominations has been given, by certified return receipt mail, to the 
Corporation's Secretary at the Corporation's principal executive 
office.  Such notice must be received by the Corporation not less than 
fifty nor more than ninety days prior to the date of the meeting.  The

meeting may refuse to acknowledge the nomination of any person not 
made in compliance with the procedures specified in this section of 
the Corporation's Bylaws.

     SECTION 14.  The Chairman of the Board of Directors, or in his 
absence, the presiding officer, shall have complete authority to 
establish the rules of conduct to be followed at any meeting of 
stockholders and to make all decisions concerning procedural issues or 
questions raised at any meeting of stockholders; provided, however, 
that the Chairman or presiding officer shall not take any action or 
make any decision that contravenes applicable state law.

                          DIRECTORS

following the most recent election of such class and when their 
successors are elected and qualified.  Notwithstanding any other 
provision of the Articles of Incorporation or these Bylaws, any 
director, or directors, including the entire Board of Directors, may 
be removed, but only for cause and by the affirmative vote of at least 
two-thirds of the issued and outstanding stock of the Corporation that 
is entitled to vote for the elections of directors, and no 
qualification for the office of director that may be provided for in 
the Articles of Incorporation or Bylaws shall apply to any director in 
office at the time such qualification was adopted or to any successor 
appointed by the remaining directors to fill the term of such 
director.

or more offices and keep the books of the Corporation outside of Utah

     SECTION 17.  In addition to the powers and authority by these 
Bylaws expressly conferred upon them, the Board of Directors may 
exercise all such powers of the Corporation and do all such lawful 
acts and things as are not by statute of the State of Utah, or by the 
Articles of Incorporation, or by these Bylaws directed or required to 
be exercised or done by the stockholders.  

                         COMMITTEES

     SECTION 18.  The Board of Directors, by resolution or resolutions 
passed by a majority of the whole Board, may designate one or more 
Committees, one of which Committees shall be known as the Executive 
Committee, and with each Committee to consist of two or more of the 
directors of the Corporation.  To the extent provided in the Articles 
of Incorporation, these Bylaws, or resolution, the Committees shall 
have and may exercise the powers conferred upon them by the Board of 
Directors; provided, however, that the Executive Committee when so 
appointed by resolution of the Board of Directors shall have and may 
exercise the power of the Board of Directors in the management of the 
business and affairs of the Corporation and may have power to 
authorize the seal of the Corporation to be affixed to all papers that 
may require it.  All Committees, except the Executive Committee, when 
so appointed, shall have such name or names as may be stated in these 
Bylaws or may be determined from time to time by resolutions adopted 
by the Board of Directors.

their services, but the Board of Directors by resolution shall fix the 
fees to be allowed and paid to directors, as such, for their services 
and provide for the payment of the expenses of the directors incurred 
by them in performing their duties.  Nothing herein contained, 
however, shall be considered to preclude any director from serving the 
Corporation in any other capacity and receiving compensation therefor.  

     SECTION 21.  Fees to members of special or standing committees 
and expenses incurred by them in the performance of their duties, 
shall also be fixed and allowed by resolution of the Board of

specifically provided by statute, by the Articles of Incorporation, or

otherwise, any acts required or permitted to be taken by the Board of 
Directors at a meeting may be taken without a meeting if all the 
directors take the action, each director signs a written consent 
describing the action taken, and the consents are filed with the 
records of the Corporation.  Action taken by consent is effective when 
the last director signs the consent, unless the consent specifies a 
different effective date.  A signed consent has the effect of a 
meeting vote and may be described as such in any document.

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)  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.



                           QUESTAR CORPORATION

                    ANNUAL MANAGEMENT INCENTIVE PLAN

            (As amended and restated effective May 19, 1998)

           Paragraph 1.  Name.  The name of this Plan is the Questar 
Corporation Annual Management Incentive Plan (the Plan).  

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

           Paragraph 3.  Administration.  The Management Performance 
Committee (Committee) of the Board of Directors 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.  

           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 the 
Company and for its major operating subsidiaries 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 the Company 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 the Company 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.  For 1992 and 
subsequent years, participants who have a target bonus of $10,000 or 
higher shall be paid all deferred portions of such bonus with restricted 
shares of the Company's common stock under the Company'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, 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 the Company's qualified 
retirement plan.  For the purpose of this Plan, disability shall mean 
any termination of service that results in payments under the Company's 
long-term disability plan.  

           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 
or approved retirement, 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 the Company's 
Deferred Compensation Plan.  In the event of termination due to 
disability or approved retirement, 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.

           A Change in Control of the Company shall be deemed to have 
occurred if (i) any "Acquiring Person" (as such term is defined in the 
Rights Agreement dated as of February 13, 1996, between the Company 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 the Company 
representing 25 percent or more of the combined voting power of the 
Company; or (ii) the following individuals cease for any reason to 
constitute a majority of the number of directors then serving:  
individuals who, as of May 19, 1998, constitute the Company'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 the Company) 
whose appointment or election by the Board or nomination for election by 
the Company's stockholders was approved or recommended by a vote of at 
least two-thirds of the directors then still in office who either were 
directors on May 19, 1998, or whose appointment, election or nomination 
for election was previously so approved or recommended; or (iii) the 
Company's stockholders approve a merger or consolidation of the Company 
or any direct or indirect subsidiary of the Company with any other 
corporation, other than a merger or consolidation that would result in 
the voting securities of the Company 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 the Company 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 the Company (or similar transaction) in which no 
person is or becomes the beneficial owner, directly or indirectly, of 
securities of the Company representing 25 percent or more of the 
combined voting power of the Company's then outstanding securities; or 
(iv) the Company'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 the Company of all or substantially all of 
the Company's assets, other than a sale or disposition by the Company 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 the Company in substantially the same 
proportions as their ownership of the Company 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 the Company'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 Company's Board of 
Directors, 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 Company's Board of Directors 
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, 1984, and 
shall remain in effect until it is suspended or terminated as provided 
by Paragraph 12.

or ordinary income recognized as a result of exercising stock options.  
Compensation shall include any base salary deferred by the Nominee

3.   PARTICIPATING CORPORATIONS

     The benefits provided to Nominees and their families by the Plan 
depend upon the employment and compensation histories of the Nominees.

     The Plan will recognize all employment with the Company including 
periods of employment with a predecessor organization immediately 
prior to the acquisition of control of such organization by the 
Company.  

     Compensation paid directly by the Company to the Nominee will be 
recognized for the purpose of determining the benefit payable under 
this Plan.  The amount of Compensation paid by any other organization 
affiliated with the Company will be recognized only if the Company's 
Board designates such organization as an eligible Participating 
Corporation, and the Board of Directors of such designated 
organization adopts a resolution agreeing to participate under the 
terms of the Plan.  A Participating Corporation may revoke future 
participation at any time, except, however, that such revocation shall 
not deprive any Nominee, Spouse, or Dependent of benefits that such 
Nominee, Spouse or Dependent is then eligible to receive.

     The benefits payable to any Nominee or to the Nominee's family 
that depend upon amounts of Compensation paid by two or more 
Participating Corporations shall be allocated among them.

     The Company may provide a funding source for benefits payable 
under the Plan by purchasing insurance policies on the lives of 
Nominees.  The premiums, cash values, loans and interest of any policy 
on the life of a Nominee whose benefits depend upon  Compensation paid 
by two or more organizations will be allocated among the Participating 
Corporations. 

4.   PARTICIPATION IN THE PLAN AND ELIGIBILITY FOR BENEFITS

     Participation in this Plan shall be limited to those key 
executive employees of the Company or its affiliates nominated prior 
to June 20, 1986, by the Company's Board  or the Board of Directors of 
a Participating Corporation.  To become eligible for Retirement 
Benefits under the Plan, a Nominee must have continued in the 
employment of the Company until completion of 15 years of service or 
the attainment of age 65, whichever first occurs.  Any Nominee who 
reaches age 65 or who has a total of 15 years of service with the 
Company (counting no single annual period of service more than once) 
and who is at such time a Nominee of more than one Participating 
Corporation, shall be eligible for Retirement Benefits as herein 
provided from all Participating Corporations having nominated such 
employee.

     The Company may impose such other terms and conditions as it 
shall deem to be desirable including but not limited to an agreement 
that the Nominee shall consult upon the request of the Company 
following retirement and shall not disclose any trade secrets or other 
confidential information and shall engage in no competitive business 
activities, directly or indirectly, after retirement.

     All Nominees who elect to participate must sign an agreement and 
consent to insurance being issued upon their lives to be paid for by 
the Company and with the Company as beneficiary and agree to terms and 
conditions above specified.  Such agreements shall not constitute an 
employment contract, and the Company may dismiss or demote such 
Nominee as an officer at any time.  The Nominee may voluntarily 
terminate employment as an officer at any time.  A Nominee who ceases 
to serve as an officer shall be terminated from this Plan and shall 
forfeit all benefit rights under this Plan unless the Nominee has 
satisfied the eligibility requirements as hereinafter provided prior 
to the date on which service as an officer ends. 

5.   RETIREMENT BENEFITS

     A Nominee who becomes eligible for retirement benefits under the 
Company's Regular Retirement Plan shall be eligible to commence 
Retirement Benefits under this Plan.  Except as set forth in Section 
6, the first payment of Retirement Benefits will be due on the first 
day of the month following retirement under the provisions of a 
Regular Retirement Plan, and payments will continue on the first of 
each month thereafter so long as the Nominee is alive.

     A Nominee who is not eligible to receive benefits under the 
Company's Regular Retirement Plan may receive Retirement Benefits 
under this Plan if declared eligible to receive such benefits by the 
Board of Directors.

     A Nominee may elect to waive any Retirement Benefits payable 
under the terms of this Plan to the extent that such benefits would be 
payable under the Company's make-up Supplemental Executive Retirement 
Plan in the absence of the Nominee's participation in this Plan.

     The basic annual retirement amount of such a Nominee shall be ten 
percent (10%) of the Final Average Earnings of the Nominee. 

6.   LUMP-SUM ELECTION

     A Nominee has a one-time election to receive the present value of 
his Retirement Benefit in a lump sum.  The Nominee shall make this 
election at least one year prior to his retirement.  The present value 
of the Retirement Benefit shall be calculated using a standard 
mortality table referred to as the "83 Group Annuity Mortality Table" 
and 80 percent of the six-month average rate for the 30-year Treasury 
bonds prior to the Nominee's retirement.  When making this election, 
the Nominee shall also indicate when the lump-sum payment shall be 
made and if it is to be made in more than one installment.  The full 
amount of any lump-sum payment, together with credited interest, must 
be paid within five years of the Nominee's retirement.  Any deferred 
payouts of lump-sum payments shall be credited with interest 
calculated at a monthly rate using the appropriate 30-year Treasury 
bond quoted in the Wall Street Journal on the first business day of 
each month.  (The appropriate 30-year Treasury bond shall be the bond 
that has the closest maturity date (by month) preceding the date on 
which the interest is to be credited.)  Any lump-sum payments that are 
not deferred shall be paid on the first business day of the month 
following the Nominee's retirement date or as soon thereafter as is 
administratively practicable.  The Nominee's spouse must consent to 
the Nominee's election to receive a lump-sum payment.  This consent 
must be in writing and must acknowledge the effect of such election.

     If the Nominee fails to timely make an election prior to his 
retirement, the Nominee shall receive monthly Retirement Benefits.

7.   FAMILY PROTECTION BENEFITS

     A Family Protection Benefit shall become payable upon the event 
that the Nominee dies in the active service of the Company or after 
retirement and leaves a surviving Spouse or Dependent.

     In the event that the Nominee dies prior to retirement and before 
having 25 years of service or satisfying the age and service 
requirements for early or normal retirement under the Company's 
Regular Retirement Plan, the amount of the Family Protection Benefit 
shall be equal to the full benefit calculated in accordance with 
Section 5 that would have been payable if the Nominee had been deemed 
to have satisfied the eligibility requirements under this Plan as of 
the date of death.  The first payment will be due on the first day of 
the month following the date of death, and payments will continue on 
the first day of each month thereafter provided that the Spouse or a 
Dependent is alive and, in the case of a Dependent, until such 
Dependent has reached his/her 18th birthday.

     In the event that the Nominee dies prior to retirement but after 
having 25 years of service or satisfying the age and service 
requirements for early or normal retirement under the Company's 
Regular Retirement Plan, the amount of the Family Protection Benefit 
shall be equal to one-half of the benefit calculated in accordance 
with Section 5 that would have been payable if the Nominee had been 
deemed to have satisfied the eligibility requirements under this Plan 
as of the date of death.  The first payment will be due on the first 
day of the month following the date of death, and payments will 
continue on the first day of the month thereafter provided that the 
Spouse or a Dependent is alive and, in the case of a Dependent, until 
such Dependent has reached his/her 18th birthday.

     In the event that the Nominee dies after retirement and did not 
elect a lump-sum, the amount of the Family Protection Benefit shall be 
equal to one-half of the Nominee's Retirement Benefits under this 
Plan.  The first payment will be due on the first day of the month 
following the date of death and payments will continue on the first of 
each month thereafter provided that the Spouse or a Dependent is alive 
and, in the case of a Dependent, until such Dependent has reached 
his/her 18th birthday.

     Family Protection Benefit payments shall be paid in full to the 
surviving Spouse or divided equally amongst those Dependents who have 
not reached their 18th birthdays in the event that there is no Spouse. 

8.   ALLOCATION OF BENEFITS

     Benefit payments from the Plan attributable to a Nominee will be 
allocated to and paid directly by the Company and the Participating 
Corporations. 

9.   FINANCING THE BENEFITS

     The Company may enter into life insurance policies on the lives 
of the Nominees to protect against the burdens of premature death and 
to provide for an orderly financing program.  The policies will be 
owned by the Company, and the proceeds will be paid to the Company.  
The Nominee will have no beneficial interest in any such insurance 
policy.

     The premium payments, cash values, loans and interest of any 
policies on the life of a Nominee for any calendar year will be 
allocated among the Participating Corporations.

     Proceeds from policies on the lives of Nominees will be allocated 
in proportion to the total benefits and premiums paid by and for which 
each Participating Corporation is ultimately responsible. 

10.  PAYMENT OF BENEFITS

     Benefits as well as premium payments will be the obligation of 
the Company and/or Participating Corporations. 

11.  ADMINISTRATION

     The Management Performance Committee of the Company's Board shall 
administer the Plan and may appoint an officer of the Company to 
assist the Committee with this responsibility.  The Board shall have 
the sole responsibility to interpret the Plan and adopt such rules and 
regulations for carrying out the Plan as it may deem necessary.  
Decisions of the Board shall be final and binding. 

12.  SUCCESSOR TO THE COMPANY

     The Company shall require any successor or assign, whether direct 
or indirect, by purchase, merger, consolidation or otherwise, to all 
or substantially all of the business and/or assets of the Company, to 
assume and agree to pay any Retirement Benefits in the same manner and 
to the same extent that the Company would be required to perform if no 
such succession or assignment had taken place.

13.  CHANGE IN CONTROL AND LEGAL FEES

     The Company shall pay all legal fees and expenses that a Retired 
Nominee or a Nominee may reasonably incur as a result of the Company's 
contesting the validity or enforceability of such person's right to 
receive benefits under the terms of this Plan following a "Change in 
Control" of the Company.    

     In the event that a Change in Control of the Company occurs and a 
Nominee's employment with the Company or its successor(s) terminates, 
the Nominee shall receive a full lump-sum payment of his Retirement 
Benefits calculated as set forth in Section 6 within 30 days of 
his/her termination.

     A Change in Control of the Company shall be deemed to have 
occurred if (i) any Acquiring Person (as such term is defined in the 
Rights Agreement dated as of February 13, 1996, between the Company 
and ChaseMellon Shareholder Services L.L.C.) 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 the Company 
representing 25 percent or more of the combined voting power of the 
Company; or (ii) the following individuals cease for any reason to 
constitute a majority of the number of directors then serving:  
individuals who, as of May 19, 1998, constitute the Company'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 the Company) 
whose appointment or election by the Board or nomination for election 
by the Company's stockholders was approved or recommended by a vote of 
at least two-thirds (2/3) of the directors then still in office who 
either were directors on May 19, 1998, or whose appointment, election 
or nomination for election was previously so approved or recommended; 
or (iii) the Company's stockholders approve a merger or consolidation 
of the Company or any direct or indirect subsidiary of the Company 
with any other corporation, other than a merger or consolidation that 
would result in the voting securities of the Company 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 the 
Company or such surviving entity or any parent thereof outstanding 
immediately after such merger or consolidation, or a merger or 
consolidation effected to implement a recapitalization of the Company 
(or similar transaction) in which no person is or becomes the 
beneficial owner, directly or indirectly, of securities of the Company 
representing 25 percent or more of the combined voting power of the 
Company's then outstanding securities; or (iv) the Company'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 the Company of all or substantially all of the 
Company's assets, other than a sale or disposition by the Company 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 the Company in substantially the 
same proportions as their ownership of the Company 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.

14.  AMENDMENT OR TERMINATION

     The Board may at any time amend, alter, modify or terminate this 
Plan; provided, however, that any such action shall not adversely 
affect the rights of any current Nominees or their Spouses or 
Dependents then eligible to receive benefits under the Plan on the 
date of such amendment, alteration, modification or termination.


EXECUTIVE SEVERANCE COMPENSATION PLAN
(As Amended and Restated effective May 19, 1998)

     Section 1.  Purpose.  Questar Corporation and its affiliated 
companies (hereinafter collectively referred to as "Questar" or the 
"Company") consider the establishment and maintenance of a sound and 
vital management to be essential to protecting and enhancing the best 
interest of the Company, its shareholders, customers, and other 
employees.  The Executive Severance Compensation Plan (hereinafter 
referred to as the "Plan") is designed to encourage the officers of 
the Company and its affiliated companies to continue to dedicate their 
full attention and energy to their duties as officers without 
distraction from the potentially disturbing circumstances arising from 
the possibility of a change in control of Questar.  

     Section 2.  Term of Plan.  This Plan was originally adopted on 
September 22, 1983, and has been amended and restated several times 
since, most recently as of May 19, 1998. The Plan as amended shall be 
automatically extended for one-year periods as of January 1 of each 
year, unless not later than September 30 of the preceding year, the 
Company, through its Board of Directors, shall determine that it does 
not wish to extend the Plan; and provided, further, that the Plan 
shall continue in effect for a period of 36 months beyond the date on 
which a "Change in Control" of the Company, as defined in Section 3, 
shall have occurred.

     Section 3.  Definitions.  The terms used in this Plan shall have 
the meanings set forth below:  

     a.   "Cause" shall mean the willful and continued failure to 
perform employment duties, after a written demand for substantial 
performance is made by the Chief Executive Officer of the Successor 
Entity or the willful engaging in conduct that is materially injurious 
to the Successor Entity.  No act or failure to act shall be considered 
"willful" unless done or omitted to be done in bad faith and without a 
reasonable belief that such action or omission was in the best 
interests of the Successor Entity.  

     b.   A "Change in Control" of the Company shall be deemed to have 
occurred if (i) any "Acquiring Person" (as such term is defined in the 
Rights Agreement dated as of February 13, 1996, between the Company 
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 the 
Company representing 25 percent or more of the combined voting power 
of the Company; or (ii) the following individuals cease for any reason 
to constitute a majority of the number of directors then serving:  
individuals who, as of May 19, 1998, constitute the Company'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 the Company) 
whose appointment or election by the Board or nomination for election 
by the Company's stockholders was approved or recommended by a vote of 
at least two-thirds of the directors then still in office 
who either were directors on May 19, 1998, or whose appointment, 
election or nomination for election was previously so approved or 
recommended; or (iii) the Company's stockholders approve a merger or 
consolidation of the Company or any direct or indirect subsidiary of 
the Company with any other corporation, other than a merger or 
consolidation that would result in the voting securities of the 
Company 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 the Company 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 
the Company (or similar transaction) in which no person is or becomes 
the beneficial owner, directly or indirectly, of securities of the 
Company representing 25 percent or more of the combined voting power 
of the Company's then outstanding securities; or (iv) the Company'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 the Company of all or substantially all of the 
Company's assets, other than a sale or disposition by the Company 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 the Company in substantially the 
same proportions as their ownership of the Company 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.

     c.   "Dependent" shall mean any member of a Participant's 
household who is eligible for benefits under specified welfare benefit 
plans sponsored by the Company or Successor Entity.

     d.   "Disability" shall mean termination of employment that 
results in payments under the Company's Long-Term Disability Plan or a 
similar plan sponsored by Successor Entity.

     e.   "Participant" shall mean a person who serves as an officer 
of the Company and/or its affiliated companies nominated by the Board 
of Directors to participate in the Plan who assents to the terms of 
the Plan by signing an agreement that incorporates the terms of the 
Plan.  (A form of the agreement is attached as Appendix A.)

     f.   "Successor Entity" shall mean the entity existing after the 
date of the Change in Control.

     g.   "Termination of Employment" shall mean involuntary 
termination of the responsibilities, status, titles, salary, or 
benefits of the respective Participant's employment, within three 
years following a Change in Control, or a voluntary termination of the 
Participant's employment if made within the "Window Period."

     h.   "Voluntary Retirement" shall mean voluntary termination of 
employment in accordance with the terms of the Company's qualified 
Retirement Plan or any retirement arrangement established for the 
Participant with his consent.

     i.   "Window Period" shall mean a thirty-day period that begins 
on the first anniversary of a Change in Control.

     Section 4.  Participation in the Plan.  Participation in this 
Plan shall be limited to Participants who accept the terms and 
conditions of the Plan by signing and returning an agreement that 
incorporates the terms of the Plan.

     Participation in the Plan is at the discretion of the Board of 
Directors of the Company.  A Participant may be terminated from the 
Plan by action by the Board of Directors taken before the date of any 
Change in Control of the Company.  

     Participants shall be automatically terminated from the Plan upon 
death, Disability, Voluntary Retirement, or termination prior to any 
Change in Control of the Company.

     Section 5.  Termination of Employment Following Change in 
Control.  In the event of any Change in Control of the Company, a 
Participant is entitled to receive the compensation and benefits 
specified in Sections 9 through 15 upon Termination of Employment, 
unless such termination occurs as a result of death, Disability, 
Voluntary Retirement, or Cause.  

     Section 6.  Notice of Termination of Employment.  To terminate 
the employment of a Participant, the Successor Entity shall notify the 
Participant, in writing, of Termination of Employment.  Such notice 
shall be mailed, postage prepaid, to the Participant at the home 
address shown on Company records and shall include a statement 
concerning the Participant's right to receive the benefits specified 
in Sections 9 through 15.  

     Termination of Employment shall not occur until proper written 
notice is given as above provided by the Successor Entity.  Until the 
Successor Entity provides such notice, a Participant is entitled to be 
paid the same compensation and benefits earned prior to the Change in 
Control.  

     To terminate employment during the Window Period, a Participant 
shall send a written notice to the Successor Entity at its principal 
place of business, which shall constitute an election of the 
Participant to receive the benefits specified in Sections 9 through 
15.

     Section 7.  Constructive Termination of Employment.  In the event 
that the Successor Entity, following a Change in Control, decreases 
the base salary, target bonus percentage, or stock option grant (or 
the equivalent) earned by or awarded to a Participant as an employee 
of the Company prior to a Change in Control and takes such action 
without securing the Participant's signed consent, the Successor 
Entity shall be deemed to have constructively terminated the 
Participant's employment.  A constructive termination shall constitute 
a Termination of Employment for purposes of the Participant's right to 
receive the compensation and benefits specified herein.

     Section 8.  Termination of Employment for Cause.  The Successor 
Entity cannot terminate the Participant's employment for Cause unless 
the Participant has willfully and continuously failed to perform his 
employment duties after receiving a written demand for substantial 
performance made by the Chief Executive Officer of the Successor 
Entity or unless the Participant has willfully engaged in conduct that 
is materially injurious to the Successor Entity after the Change in 
Control.  For purposes of this Section, no act, or failure to act, by 
a Participant shall be deemed "willful" unless done, or omitted to be 
done, by a Participant not in good faith and without reasonable belief 
that his action or omission was in the best interests of the Successor 
Entity.  The Successor Entity, through its Board of Directors, must 
notify the Participant in writing that the employment is being 
terminated for Cause.  The Notice of Termination shall include a list 
of factual findings to sustain the judgment that the Participant's 
employment has been terminated for Cause.  After receiving a Notice of 
Termination for Cause, the Participant shall have the right to seek 
arbitration or legal review of the Successor Entity's determination 
that the employment was terminated for Cause and to continue receiving 
all salary and benefits in effect prior to receipt of the Notice of 
Termination until the conclusion of such arbitration or legal review 
proceedings or the expiration of one year from the date of the receipt 
of the Notice of Termination, whichever event occurs first.

     In the event that arbitration or legal review proceedings do not 
uphold the Termination of Employment for Cause, the Participant shall 
have the right to receive the benefits specified in Sections 9 through 
15, but such benefits shall be reduced by the benefits received during 
the pendency of the arbitration or legal review proceedings.

     Section 9.  Compensation and Benefits.  

     a.   Upon Termination of Employment following a Change in 
Control, a Participant is entitled to receive a cash payment equal to 
twice the annual salary at the rate in effect for such Participant 
immediately prior to the Change in Control.  The Participant is also 
entitled to receive a cash payment equal to twice the higher of the 
average annual amount earned by the Participant under the Annual 
Management Incentive Plan ("AMIP") and any other annual incentive 
compensation plans maintained by the Company for the three years 
preceding a Change in Control or the average annual target amount 
specified under such plans for the years in question.  (The AMIP is 
described in Appendix B to this Plan.)  Any Participant whose 
employment is terminated at any time after the date of a Change in 
Control of the Company is also entitled to receive the amounts 
previously awarded or allocated to or earned by him under the AMIP and 
any other annual incentive compensation plans then in effect. 

     Any compensation and benefits payable under the terms of this 
Plan shall be payable, in a single lump-sum payment within ten days of 
Termination of Employment.  

     b.   Upon Termination of Employment, the Participant is entitled 
to receive a pro rata bonus payment under the AMIP and any other 
annual incentive compensation plans in effect for the year in which 
the Termination of Employment occurred and shall be based on the 
portion of such year the Participant was employed.  The full amount of 
this bonus payment shall be payable in a single lump-sum payment 
within 60 days after the end of the year in which his employment 
terminated.

     Section 10.  Deferred Compensation Benefits.  Upon ceasing to be 
employed by the Successor Entity at any time of a Change in Control of 
the Company, a Participant is also entitled to receive the amounts 
previously deferred by him under the Company's AMIP, Deferred 
Compensation Plan for Directors, Deferred Compensation Plan, Deferred 
Share Plan, Deferred Share Make-Up Plan, and other deferred 
compensation plans then in effect.  (The Company's deferred 
compensation plans are described in Appendix B.)

     Notwithstanding any other provisions of such deferred 
compensation plans, lump-sum distributions of account balances shall 
be automatically distributed within 30 days following the Change in 
Control.

     Section 11.  Supplemental Retirement Benefits.  

     a.   Upon Termination of Employment, a Participant who has a 
vested right under the Company's Retirement Plan shall be entitled to 
receive a supplemental retirement benefit equal to the difference 
between the amount payable to him under the terms of the Company's 
Retirement Plan and the amount that would have been payable to him had 
he been credited with two additional years of service under the 
Company's Retirement Plan.  Benefits payable hereunder shall be 
calculated using the Participant's annual compensation (as the term 
"compensation" is defined in the Company's Supplemental Executive 
Retirement Plan ("SERP") or Special Situation Retirement Plan 
("SERP2") and other supplemental retirement plans then in effect) for 
the last full year prior to the Termination of Employment as his 
compensation for the additional years of service credited to the 
Participant under the terms of this provision.  Upon Termination of 
Employment, a Participant who does not have a vested right under the 
Company's Retirement Plan at such time shall be entitled to receive a 
supplemental retirement benefit equal to the amount that would have 
been payable to him under the terms of the Company's Retirement Plan 
and SERP or SERP2 had he become vested under the terms of such Plans 
if he had continued in the Company's employment for the two-year 
period of time following his Termination of Employment after the 
Change in Control.  (The Company's supplemental retirement plans are 
described in Appendix B.)

     b.   Upon Termination of Employment, a Participant who is 
entitled to receive supplemental retirement benefits under the terms 
of the Company's SERP or SERP2 shall be entitled to receive such 
benefits.  Benefits payable under the Company's SERP or SERP2 shall be 
calculated using the Participant's annual compensation (as the term 
compensation is defined in the Company's SERP or SERP2) for the last 
full year prior to the Termination of Employment as his compensation 
for the two additional years of service credited to the Participant 
under the terms of this provision. 

     c.  Any Participant who is a Nominee in the Company's Executive 
Incentive Retirement Plan ("EIRP") and who has satisfied the 
eligibility requirements contained in the EIRP at the date of a Change 
in Control of the Company shall have the right to receive the 
retirement benefits specified in the EIRP.  The Participant's 
surviving spouse and dependent children shall also have the right to 
receive the family protection benefits specified in the EIRP in the 
event of the Participant's death.  

     Section 12.  Special Lump-Sum Provision.  Upon Termination of 
Employment, a Participant shall receive a single-installment, lump-sum 
payment of supplemental retirement benefits under the EIRP, SERP and 
SERP2.  The present value of such benefits shall be calculated using a 
standard mortality table referred to as the "83 Group Annuity 
Mortality Table" and 80 percent of the six-month average rate for the 
30-year Treasury bonds (using the six-month period ending prior to the 
Participant's Termination of Employment).  This lump-sum payment shall 
be made within 30 days of a Participant's Termination of Employment.

     Section 13.  Stock Options and Restricted Stock.  Upon a Change 
in Control, all stock options and stock appreciation rights granted 
under the Company's Long-Term Stock Incentive Plan and its successors 
shall vest.  A Participant shall have 60 days following a Change in 
Control to exercise any vested stock options and stock appreciation 
rights, notwithstanding a Termination of Employment, or to receive a 
cash payment equal to the value of such vested stock options.  Upon a 
Change in Control, all shares of restricted stock granted as partial 
payment of earned bonuses under the AMIP or other annual incentive 
compensation plans adopted by the Company shall immediately vest free 
of restrictions and shall be distributed.

     Section 14.  Miscellaneous Benefits.  Upon Termination of 
Employment at any period of time within three years from the date of a 
Change in Control of the Company, a Participant shall receive (for 
himself and his Dependents), at the sole expense of the Successor 
Entity, life, disability, accident and health insurance benefits, or a 
payment to reimburse for coverage obtained by the Participant, 
substantially similar to those received or eligible to be received 
prior to Termination of Employment, for a period of six months 
following Termination of Employment, unless within such period the 
Participant chooses to take Voluntary Retirement, in which event the 
Participant will be entitled to receive the same benefits as any 
eligible employee choosing to retire prior to the Change in Control.  

     Section 15.  Tax Provision.  The benefits payable under the terms 
of the Plan (excluding any benefits earned prior to the Termination of 
Employment), are collectively referred to as "Severance Payments."  
The Severance Payments are designed to be fully deductible under 
Section 280G of the Internal Revenue Code of 1986, as amended (the 
"Code").  However, if any portion of the Severance Payments will be 
subject to the excise tax ("Excise Tax") imposed by Section 4999 of 
the Code, the Company or Successor Entity shall pay to the Participant 
at the time specified in Section 9 an additional estimated amount (the 
"Gross-Up Payment") such that the net amount retained by the 
Participant, after deduction of any Excise Tax on the Severance 
Payments and any federal and state taxes payable on the Gross-Up 
Payment, shall be equal to the Severance Payments (adjusted for 
applicable federal and state taxes).  In the event that the Excise Tax 
is subsequently determined to be less than the amount taken into 
account at the time of the Participant's Termination of Employment, 
the Participant shall repay to the Successor Entity the portion of the 
Gross-Up Payment attributable to the Excise Tax and federal and state 
income tax imposed on the Gross-Up payment being repaid by the 
participant if such repayment results in a reduction in Excise Tax and 
federal and state income tax deduction plus interest on the amount of 
such repayment at the applicable rate (as defined in Section 174(d) of 
the Code).  In the event that the Excise Tax is determined to exceed 
the amount taken into account at the time of Termination of Employment 
(including by reason of any payment that is unknown or undetermined at 
the time of the Gross-Up Payment), the Successor Entity shall make an 
additional payment in respect of such excess (plus any interest 
payable with respect to such excess) at the time that the amount of 
such excess is finally determined.

     Section 16.  Binding Agreement.  Any and all agreements entered 
into pursuant to this Plan with individual officers of the Company 
shall be binding upon any Successor Entity as defined above.  The 
Company will require any Successor Entity to expressly assume and 
agree to perform such agreements.  Failure of the Company to obtain 
such assumption and agreement prior to the effective date of control 
by the Successor Entity shall be a breach of the agreement entered 
into pursuant to the terms of the Plan and shall entitle Participants 
to receive compensation from the Company in the same amount and on the 
same terms as they would otherwise be entitled to receive, except that 
the day prior to the date upon which the Successor Entity obtains 
control shall be deemed the date of Termination of Employment.

     Section 17.  Miscellaneous.  

     a.   Except as set forth in Section 18, no provisions outlined in 
this Plan and the separate agreements entered into pursuant to such 
Plan may be modified, waived, or discharged after the date of a Change 
in Control unless such waiver, modification, or discharge is agreed to 
in writing by the Participant.  No waiver by either a Participant or 
Successor Entity at any time or any breach of any condition or 
provision of this Plan or the separate agreements entered into 
pursuant to this Plan shall be deemed a waiver of similar or 
dissimilar provisions or conditions at the time or at any prior or 
subsequent time.  

     b.   The validity, interpretation, construction and performance 
of this Plan and the separate agreements entered into pursuant to such 
Plan shall be governed by the laws of the State of Utah.  

     c.   The invalidity or unenforceability of any provision of this 
Plan and the separate agreements entered pursuant to such Plan shall 
not affect the validity or enforceability of any other provision of 
the Plan and the separate agreements, which shall remain in full force 
and effect.  

     d.   The Participants are entitled to receive the benefits 
specified in Sections 9 through 15 of this Plan in accordance with the 
terms of the Plan.  Such benefits are not to be construed as 
"damages."   

     e.   Upon written request by the Participant, the Successor 
Entity shall be obligated to pay the legal fee, and expenses incurred 
by any Participant reasonably expended to obtain, protect or enforce 
any right or benefit provided by this Plan and the individual 
agreements executed pursuant to such Plan.  The Successor shall be 
obligated to reimburse the Participant for legal fees within 30 days 
of receiving the Participant's request for reimbursement.

     Section 18.  Amendment or Termination of Plan.  This Plan and the 
individual agreements entered into pursuant to this Plan may be 
amended or terminated by action of the Company's Board of Directors 
taken prior to a Change in Control of the Company.  Notwithstanding 
any other provision of the Plan to the contrary, in the event that the 
consummation of a Change in Control is contingent on using pooling of 
interest accounting methodology, the Board of Directors may take any action
necessary to preserve the use of pooling of interest accounting.

Section 8 of the Plan expressed as a share of Common Stock.

     "Restricted Period" shall mean the period of years selected by 
the Committee during which a grant of Restricted Stock or Restricted 
Stock Units may be forfeited to the Company.

     "Restricted Stock" shall mean shares of Common Stock contingently 
granted to a Participant under Section 9 of the Plan.

     "Restricted Stock Unit" shall mean a fixed or variable dollar 
denominated unit contingently awarded under Section 9 of the Plan.

     "Right" shall mean a Stock Appreciation Right granted under 
Section 7.

     "Stock Unit Award" shall mean an Award of Common Stock or units 
granted under Section 10.

     "Termination of Employment" shall mean the date on which a

resignation, in the case of a voluntary termination; and the date on 
which the Company actually notifies the Participant of his/her 
termination, in the case of an involuntary termination.  This term, as 
defined, does not include termination of employment as the result of 
an Approved Retirement, Disability, or death.

Section 3.  Administration

     The Plan shall be administered by the Committee.  The Committee 
shall have sole and complete authority to adopt, alter and repeal such 
administrative rules, guidelines and practices governing the operation 
of the Plan, and to interpret the terms and provisions of the Plan.  
The Committee's decisions shall be binding upon all persons, including 
the Company, stockholders, an Employer, Employees, Participants and 
Designated Beneficiaries.

Section 4.  Eligibility

     Awards may only be granted to officers and key employees of or 
consultants to the Company or any Affiliate who have the capacity to 
contribute to the success of the Company.  When selecting Participants 
and making Awards, the Committee may consider such factors as the 
Employee's functions and responsibilities and the Employee's past, 
present and future contributions to the Company's profitability and 
growth.

     Neither the members of the Committee nor any member of the Board 
who is not an Employee of the Company shall be eligible to receive 
awards.

     Nothing contained in the Plan or in any individual agreement 
pursuant to the terms of the Plan shall confer upon any Participant 
any right to continue in the employment of the Company or to limit in 
any respect the right of the Company to terminate the Participant's 
employment at any time and for any reason.

Section 5.  Maximum Amount Available for Awards and Maximum Award

     The aggregate number of shares of Common Stock that may be issued 
under Awards pursuant to this Plan on an annual basis shall not exceed 
one percent (1%) of the issued and outstanding shares of Common Stock 
as of the first day of each calendar year for which the Plan is in 
effect.  Any shares available in any year using this formula that are 
not granted under this Plan or other plans in which stock is awarded 
to Employees would be available for use in subsequent years.  Shares 
of Common Stock may be made available from the authorized but unissued 
shares of the Company or from shares reacquired by the Company, 
including shares purchased in the open market.  In the event that an 
Option or Right expires or is terminated unexercised as to any shares 
of Common Stock covered thereby, or any Award in respect of shares is 
forfeited for any reason under the Plan, such shares, to the extent 
not precluded by applicable law or regulation, shall be again 
available for Awards pursuant to the Plan.

     In the event that the Committee shall determine that any stock 
dividend, extraordinary cash dividend, recapitalization, 
reorganization, merger, consolidation, split-up, spin-off, 
combination, exchange of shares, warrants or rights offering to 
purchase Common Stock at a price substantially below fair market value 
or other similar corporate event affects the Common Stock such that an 
adjustment is required in order to preserve the benefits or potential 
benefits intended to be made available under this Plan, then the 
Committee, in its sole discretion, may take action.  The Committee may 
adjust any or all of the number and kind of shares that thereafter may 
be awarded or optioned and sold or made the subject of Rights under 
the Plan, the number and kind of shares subject to outstanding Options 
and other Awards, and the grant, exercise or conversion price with 
respect to any of the foregoing and/or, if deemed appropriate, make 
provision for a cash payment to a Participant or a person who has an 
outstanding Option or other Award.  

     There is a maximum of 100,000 shares that can be the subject of 
Awards granted to any single Participant in any given fiscal year.

Section 6.  Stock Options

     (a)  Grant.  Subject to the provisions of the Plan, the Committee 
shall have sole and complete authority to determine the Employees to 
whom Options shall be granted, the number of shares to be covered by 
each Option, the option price therefor and the conditions and 
limitations, applicable to the exercise of the Option.  The Committee 
shall have the authority to grant Incentive Stock Options, 
Nonqualified Stock Options, or both types of Options.  In the case of 
Incentive Stock Options, the terms and conditions of such grants shall 
be subject to and comply with such rules as may be prescribed by 
Section 422 of the Code and any implementing regulations.

     (b)  Option Price.  The Committee shall establish the option 
price at the time each Option is granted, which price shall not be 
less than 100 percent of the Fair Market Value of the Common Stock on 
the date of grant.

     (c)  Exercise.  Each Option shall be exercisable at such times 
and subject to such terms and conditions as the Committee, in its sole 
discretion, may specify in the applicable Award or thereafter; 
provided, however, that in no event may any Option granted hereunder 
be exercisable earlier than six months after the date of such grant or 
after the expiration of ten years from the date of such grant.  The 
Committee may impose such conditions with respect to the exercise of 
Options, including without limitation, any conditions relating to the 
application of federal or state securities laws, as it may deem 
necessary or advisable.

     No shares shall be delivered pursuant to any exercise of an 
Option until payment in full of the option price is received by the 
Company.  Such payment may be made in cash, or its equivalent, or, if 
and to the extent permitted by the Committee, by exchanging shares of 
Common Stock owned by the optionee (which are not the subject of any 
pledge or other security interest), or by a combination of the 
foregoing, provided that the combined value of all cash and cash 
equivalents and the Fair Market Value of any such Common Stock so 
tendered to the Company, valued as of the date of such tender, is at 
least equal to such option price.

     (d)  Transferability.  Participants are allowed to transfer 
vested Nonqualified Stock Options to Family Members or family trusts, 
provided that such options were granted as of and after February 10, 
1998 and provided that such transfers are made and transferred Options 
are exercised in accordance with procedural rules adopted by the 
Committee.

Section 7.  Stock Appreciation Rights

     (a)  The Committee may, with sole and complete authority, grant 
Rights in tandem with an Option.  Rights shall not be exercisable 
earlier than six months after grant, shall not be exercisable after 
the expiration of ten years from the date of grant and shall have an 
exercise price of not less than 100 percent of the Fair Market Value 
of the Common Stock on the date of grant.

     (b)  A Right shall entitle the Participant to receive from the 
Company an amount equal to the excess of the Fair Market Value of a 
share of Common Stock on the exercise of the Right over the grant 
price thereof.  The Committee shall determine whether such Right shall 
be settled in cash, shares of Common Stock or a combination of cash 
and shares of Common Stock.

Section 8.  Performance Shares

     (a)  The Committee shall have sole and complete authority to 
determine the Employees who shall receive Performance Shares and the 
number of such shares for each Performance Period and to determine the 
duration of each Performance Period and the value of each Performance 
Share.  There may be more than one Performance Period in existence at 
any one time, and the duration of Performance Periods may differ from 
each other.

     (b)  Once the Committee decides to use Performance Shares, it 
shall establish Performance Goals for each Period on the basis of 
criteria selected by it.  During any Period, the Committee may adjust 
the Performance Goals for such Period as it deems equitable in 
recognition of unusual or non-recurring events affecting the Company, 
changes in applicable tax laws or accounting principles, or such other 
factors as the Committee may determine.

     (c)  As soon as practicable after the end of a Performance 
Period, the Committee shall determine the number of Performance Shares 
that have been earned on the basis of performance in relation to the 
established Performance Goals.  Payment Values of earned Performance 
Shares shall be distributed to the Participant or as soon as 
practicable after the expiration of the Performance Period and the 
Committee's determination.  The Committee shall determine whether 
Payment Values are to be distributed in the form of cash and/or shares 
of Common Stock.

Section 9.  Restricted Stock and Restricted Stock Units

     (a)  Subject to the provisions of the Plan, the Committee shall 
have sole and complete authority to determine the Employees to whom 
shares of Restricted Stock and Restricted Stock Units shall be 
granted, the number of shares of Restricted Stock and the number of 
Restricted Stock Units to be granted to each Participant, the duration 
of the Restricted Period during which and the conditions under which 
the Restricted Stock and Restricted Stock Units may be forfeited to 
the Company, and the other terms and conditions of such Awards.

     (b)  Shares of Restricted Stock and Restricted Stock Units may 
not be sold, assigned, transferred, pledged or otherwise encumbered, 
except as herein provided, during the Restricted Period.  At the 
expiration of the Restricted Period, the Company shall deliver such 
certificates to the Participant or the Participant's legal 
representative.  Payment for Restricted Stock Units shall be made to 
the Company in cash and/or shares of Common Stock, as determined at 
the sole discretion of the Committee.

Section 10.  Other Stock Based Awards

     (a)  In addition to granting Options, Rights, Performance Shares, 
Restricted Stock, Restricted Stock Units, the Committee shall have 
authority to grant Stock Unit Awards to Participants that can be in 
the form of Common Stock or units, the value of which is based, in 
whole or in part, on the value of Common Stock.  Subject to the 
provisions of the Plan, Stock Unit Awards shall be subject to such 
terms, restrictions, conditions, vesting requirements and payment 
rules as the Committee may determine in its sole and complete 
discretion at the time of grant.

     (b)  Any shares of Common Stock that are part of a Stock Unit 
Award may not be assigned, sold, transferred, pledged or otherwise 
encumbered prior to the date on which the shares are issued or, if 
later, the date provided by the Committee at the time of grant of the 
Stock Unit Award.

     Stock Unit Awards may provide for the payment of cash 
consideration by the person to whom such Award is granted or provide 
that the Award, and any Common Stock to be issued in connection 
therewith, if applicable, shall be delivered without the payment of 
cash consideration, provided that for any Common Stock to be purchased 
in connection with a Stock Unit Award the purchase price shall be at 
least 50 percent of the Fair Market Value of such Common Stock on the 
date such Award is granted.

     Stock Unit Awards may relate in whole or in part to certain 
performance criteria established by the Committee at the time of 
grant.  Stock Unit Awards may provide for deferred payment schedules 
and/or vesting over a specified period of employment.  In such 
circumstances as the Committee may deem advisable, the Committee may 
waive or otherwise remove, in whole or in part, any restriction or 
limitation to which a Stock Unit Award was made subject at the time of 
grant.

     (c)  In the sole and complete discretion of the Committee, an 
Award, whether made as a Stock Unit Award under this Section 10 or as 
an Award granted pursuant to Sections 6 through 9, may provide the 
Participant with dividends or dividend equivalents (payable on a 
current or deferred basis) and cash payments in lieu of or in addition 
to an Award.

Section 11.  Termination of Employment

     The following provisions define a Participant's status in the 
event of termination of employment:

     (a)  Options and Rights.  If a Participant shall cease to be 
employed by the Company or an Affiliate either directly or in a 
consulting role, any Option and any Right granted to him under the 
Plan shall terminate in accordance with the following rules:

          (1)  A Participant who terminates employment for any reason 
other than Approved Retirement, Disability or death shall lose the 
right to exercise any Options or Rights as of Termination of 
Employment.  Any Options transferred to a Family Member or family 
trust shall also be terminated as of the Participant's Termination of 
Employment for any reason other than Approved Retirement, Disability, 
or death.

          (2)  A Participant who terminates employment as a result of 
an Approved Retirement shall have a period of time specified in the 
individual agreements by which Options are granted to exercise such 
Options or Rights.

          (3)  A Participant who is Disabled shall have 12 months 
after Termination of Employment in which to exercise an Option or 
Right.

          (4)  Upon the death of a Participant during employment, the 
Participant's Designated Beneficiary shall have 12 months from the 
date of death to exercise the Participant's Option or Right.  Upon the 
death of a Participant after an Approved Retirement but within the 
period specified by the Committee to exercise Options or Rights after 
the Participant's Approved Retirement, the Participant's Designated 
Beneficiary shall have the period specified by the Committee to 
exercise the Option or Right.

          (5)  The foregoing notwithstanding, a Participant or the 
Participant's Designated Beneficiary shall not be permitted to 
exercise an Option or Right after the expiration date.

     (b)  Restricted Stock.  If a Participant terminates employment 
before the end of the Restricted Period for a reason other than death, 
Approved Retirement, Disability, or Change of Control, the Participant 
shall forfeit all shares of Restricted Stock as of Termination of 
Employment.  If a Participant terminates employment as a result of 
death, Approved Retirement, or Change of Control, the Committee, in 
its sole discretion, shall determine what portion, if any, of the 
Restricted Stock shall be freed from restrictions.

     (c)  Performance Shares and Other Awards.  If a Participant 
ceases to be an Employee before the end of any Performance Period as a 
result of death, Approved Retirement, or Disability, the Committee may 
authorize the payment to such Participant or his Designated 
Beneficiary of a pro rata portion of the amount that would have been 
paid to him had he continued as an Employee to the end of the 
Performance Period.  In the event a Participant terminates employment 
for any other reason, any amounts for outstanding Performance Periods 
shall be forfeited as of Termination of Employment.

Section 12.  General Provisions

     (a)  Withholding.  The Employer shall have the right to deduct 
from all amounts paid to a Participant in cash any taxes required by 
law to be withheld in respect of Awards under this Plan.  In the case 
of payments of Awards in the form of Common Stock, the Committee shall 
require the Participant to pay to the Employer the amount of any taxes 
required to be withheld with respect to such Common Stock, or, in lieu 
thereof, the Employer shall have the right to retain (or the 
Participant may be offered the opportunity to elect to tender) the 
number of shares of Common Stock whose Fair Market Value equals the 
amount required to be withheld.

     (b)  Awards.  Each Award shall be evidenced in writing delivered 
to the Participant and shall specify the terms and conditions and any 
rules applicable to such Award.

     (c)  Nontransferability.  Except as provided in Section 6(d), no 
Award shall be assignable or transferable, and no right or interest of 
any Participant shall be subject to any lien, obligation or liability 
of the Participant, except by will or the laws of descent and 
distribution.

     (d)   No Rights as Stockholder.  Subject to the provisions of the 
applicable Award, no Participant or Designated Beneficiary shall have 
any rights as a stockholder with respect to any shares of Common Stock 
to be distributed under the Plan until becoming the holder.  
Notwithstanding the foregoing, in connection with each grant of 
Restricted Stock hereunder, the applicable Award shall specify if and 
to what extent the Participant shall not be entitled to the rights of 
a stockholder in respect of such Restricted Stock.

     (e)  Construction of the Plan.  The validity, construction, 
interpretation, administration and effect of the Plan and of its rules 
and regulations, and rights relating to the Plan, shall be determined 
solely in accordance with the laws of Utah.

     (f)  Effective Date.  Subject to the approval of the stockholders 
of the Company, the Plan shall be effective on March 1, 1991.  No 
Options or Awards may be granted under the Plan, however, until the 
Plan is approved by the Company's shareholders or after May 20, 2001.  

     (g)  Amendment of Plan.  The Board of Directors may amend, 
suspend or terminate the Plan or any portion thereof at any time, 
provided that no amendment shall be made without stockholder approval 
if such approval is necessary to comply with any tax or regulatory 
requirement, including for these purposes any approval requirement 
that is a prerequisite for exemptive relief under Section 16(b) of the 
Securities Exchange Act of 1934.  

     (h)  Amendment of Award.  The Committee may amend, modify or 
terminate any outstanding Award with the Participant's consent at any 
time prior to payment or exercise in any manner not inconsistent with 
the terms of the Plan, including without limitation, to change the 
date or dates as of which an Option or Right becomes exercisable; a 
Performance Share is deemed earned; Restricted Stock becomes 
nonforfeitable; or to cancel and reissue an Award under such different 
terms and conditions as it determines appropriate.

Section 13.  Change of Control.

     In the event of a Change of Control of the Company, all Options, 
Restricted Stock, and other Awards granted under the Plan shall vest 
immediately. 

     A Change in Control of the Company shall be deemed to have 
occurred if (i) any "Acquiring Person" (as such term is defined in the 
Rights Agreement dated as of February 13, 1996, between the Company 
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 the 
Company representing 25 percent or more of the combined voting power 
of the Company; or (ii) the following individuals cease for any reason 
to constitute a majority of the number of directors then serving:  
individuals who, as of May 19, 1998, constitute the Company's Board of 
Directors 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 the Company) whose 
appointment or election by the Board or nomination for election by the 
Company's stockholders was approved or recommended by a vote of at 
least two-thirds of the directors then still in office who either were 
directors on May 19, 1998, or whose appointment, election or 
nomination for election was previously so approved or recommended; or 
(iii) the Company's stockholders approve a merger or consolidation of 
the Company or any direct or indirect subsidiary of the Company with 
any other corporation, other than a merger or consolidation that would 
result in the voting securities of the Company 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 the Company 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 the Company (or similar transaction) 
in which no person is or becomes the beneficial owner, directly or 
indirectly, of securities of the Company representing 25 percent or 
more of the combined voting power of the Company's then outstanding 
securities; or (iv) the Company'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 the Company of 
all or substantially all of the Company's assets, other than a sale or 
disposition by the Company 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 the Company in substantially the same proportions as 
their ownership of the Company 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.


                        QUESTAR CORPORATION
             DEFERRED COMPENSATION PLAN FOR DIRECTORS
              (As Amended and Restated May 19, 1998)

 1.  Purpose of Plan.

          The purpose of the Deferred Compensation Plan for Directors 
     ("Plan") is to provide Directors of Questar Corporation (the 
     "Company") with an opportunity to defer compensation paid to them 
     for their services as Directors.

 2.  Eligibility.

          Subject to the conditions specified in this Plan or 
     otherwise set by the Executive Committee of the Company's Board 
     of Directors, all voting Directors of the Company who receive 
     compensation for their service as Directors are eligible to 
     participate in the Plan.  Eligible Directors are referred to as 
     "Directors."  Directors who elect to defer receipt of fees or who 
     have account balances are referred to as "Participants" in this 
     Plan.

 3.  Administration.

          The Company's Board of Directors shall administer the Plan 
     and shall have full authority to make such rules and regulations 
     deemed necessary or desirable to administer the Plan and to 
     interpret its provisions.

 4.  Election to Defer Compensation.

          (a)  Time of Election.  A Director can elect to defer future 
     compensation or to change the nature of his election for future 
     compensation by submitting a notice prior to the beginning of the 
     calendar year.  A newly elected Director is entitled to make a 
     choice within five days of the date of his election or 
     appointment to serve as a Director to defer payment of 
     compensation for future service.  An election shall continue in 
     effect until the termination of the Participant's service as a 
     Director or until the end of the calendar year during which the 
     Director serves written notice of the discontinuance of his 
     election.

          All notices of election, change of election, or 
     discontinuance of election shall be made on forms prepared by the 
     Corporate Secretary and shall be dated, signed, and filed with 
     the Corporate Secretary.  A notice of change of election or 
     discontinuance of election shall operate prospectively from the 
     beginning of the calendar year, but any compensation deferred 
     shall continue to be held and shall be paid in accordance with 
     the notice of election under which it was withheld.

          (b)  Amount of Deferral.  A Participant may elect to defer 
     receipt of all or a specified portion of the compensation payable 
     to him for serving as a Director and attending Board and 
     Committee Meetings as a Director.  For purposes of this Plan, 
     compensation does not include any funds paid to a Director to 
     reimburse him for expenses or any income recognized by him as a 
     result of exercising options under the Company's Stock Option 
     Plan for Directors.

          (c)  Period of Deferral.  When making an election to defer 
     all or a specified percentage of his compensation, a Participant 
     shall elect to receive the deferred compensation in a lump sum 
     payment within 45 days following the end of his service as a 
     Director or in a number of annual installments (not to exceed 
     four), the first of which would be payable within 45 days 
     following the end of his service as a Director with each 
     subsequent payment payable one year thereafter.  Under an 
     installment payout, the Participant's first installment shall be 
     equal to a fraction of the balance in his Deferred Compensation 
     Account as of the last day of the calendar month preceding such 
     payment, the numerator of which is one and the denominator of 
     which is the total number of installments selected.  The amount 
     of each subsequent payment shall be a fraction of the balance in 
     the Participant's Account as of the last day of the calendar 
     month preceding each subsequent payment, the numerator of which 
     is one and the denominator of which is the total number of 
     installments elected minus the number of installments previously 
     paid.  The term "balance," as used herein, refers to the amount 
     credited to a Participant's Account or to the Fair Market Value 
     (as defined in Section 5 (a)) of the Phantom Shares of the 
     Company's Common Stock credited to his Account.

          (d)  Phantom Stock Option and Certificates of Deposit 
     Option.  When making an election to defer all or a specified 
     percentage of his compensation, a Participant shall choose 
     between two methods of determining earnings on the deferred 
     compensation.  He may choose to have such earnings calculated as 
     if the deferred compensation had been invested in the Company's 
     Common Stock at the Fair Market Value (as defined in Section 5 
     (a)) of such stock as of the date such compensation amount would 
     have otherwise been payable to him ("Phantom Stock Option") or 
     may choose to have earnings calculated as if the deferred 
     compensation had been invested in negotiable certificates of 
     deposit at the time such compensation would otherwise be payable 
     to him ("Certificates of Deposit Option").

          The Participant must choose between the two options for all 
     of the compensation he elects to defer in any given year.  He may 
     change the option for future compensation by filing the 
     appropriate notice with the Corporate Secretary before the first 
     day of each calendar year, but such change shall not affect the 
     method of determining earnings for any compensation deferred in a 
     prior year.

 5.  Deferred Compensation Account.

          A Deferred Compensation Account ("Account") shall be 
     established for each Participant.

          (a)  Phantom Stock Option Account.  If a Participant elects 
     the Phantom Stock Option, his Account will include the number of 
     shares and partial shares of the Company's Common Stock (to four 
     decimals) that could have been purchased on the date such 
     compensation would have otherwise been payable to him.  The 
     purchase price for such stock is the Fair Market Value of such 
     stock, i.e., the closing price of such stock as reported on the 
     Composite Tape of the New York Stock Exchange for such date or 
     the next preceding day on which sales took place if no sales 
     occurred on the actual payable date.

          The Participant's Account shall also include the dividends 
     that would have become payable during the deferral period if 
     actual purchases of Common Stock had been made, with such 
     dividends treated as if invested in Common Stock as of the 
     payable date for such dividends.

          (b)  Certificates of Deposit Option Account.  If a 
     Participant elects the Certificates of Deposit Option, his 
     Account will be credited with any compensation deferred by the 
     Participant at the time such compensation would otherwise be 
     payable and with interest calculated at a monthly rate using the 
     typical rates paid by major banks on new issues of negotiable 
     Certificates of Deposit on amounts of $1,000,000 or more for one 
     year as quoted in The Wall Street Journal under "Money Rates" 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.  The interest credited to each Account shall be 
     based on the amount held in the Account at the beginning of each 
     particular month.

 6.  Statement of Deferred Compensation Account.

          Within 45 days after the end of the calendar year, a 
     statement will be sent to each Participant listing the balance in 
     his Account as of the end of the year.

7.   Retirement

          Upon retirement or resignation as a Director from the Board 
     of Directors or upon appointment as a non-voting Senior Director, 
     a Participant shall receive payment of the balance in his Account 
     in accordance with the terms of his prior instructions and the 
     terms of the Plan.  Upon appointment as a non-voting Senior 
     Director of the Company, a Participant shall also receive payment 
     of account balances under any other Deferred Compensation Plans 
     maintained by the Company's affiliates unless the Participant 
     serves as a Director of the affiliate maintaining the account 
     balance.

 8.  Payment of Deferred Compensation.

          (a)  Phantom Stock Option.  The amount payable to the 
     Participant choosing the Phantom Stock Option shall be the cash 
     equivalent of the stock using the Fair Market Value of such stock 
     on the date of withdrawal.

          (b)  Certificates of Deposit Option.  The amount payable to 
     the Participant choosing the Certificate of Deposit Option shall 
     include the interest on all sums credited to the Account, with 
     such interest credited to the date of withdrawal.

          (c)  The date of withdrawal for both the Phantom Stock 
     Option Account and the Certificates of Deposit Option Account 
     shall be the last day of the calendar month preceding payment or 
     if payment is made because of death, the date of death.

          (d)  The payment shall be made in the manner (lump sum or 
     installment) chosen by the Participant.  In the event of a 
     Participant's death, payment shall be made within 45 days of the 
     Participant's death to the beneficiary designated by the 
     Participant or, in the absence of such designation, to the 
     Participant's estate.

 9.  Payment, Change in Control

          Notwithstanding any other provisions of this Plan or 
     deferral elections made pursuant to Section 4 of this Plan, a 
     Director, in the event of a Change in Control of the Company, 
     shall be entitled to elect a distribtuion of his account balance 
     within 60 days following the date of a Change in Control.

          A "Change in Control" of the Company shall be deemed to have 
     occurred if (i) any "Acquiring Person" (as such term is defined 
     in the Rights Agreement dated as of February 13, 1996, between 
     the Company 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 the Company representing 25 percent or more of the 
     combined voting power of the Company; or (ii) the following 
     individuals cease for any reason to constitute a majority of the 
     number of directors then serving:  individuals who, as of May 19, 
     1998, constitute the Company'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 the Company) whose 
     appointment or election by the Board or nomination for election 
     by the Company's stockholders was approved or recommended by a 
     vote of at least two-thirds of the directors then still in office 
     who either were directors on May 19, 1998, or whose appointment, 
     election or nomination for election was previously so approved or 
     recommended; or (iii) the Company's stockholders approve a merger 
     or consolidation of the Company or any direct or indirect 
     subsidiary of the Company with any other corporation, other than 
     a merger or consolidation that would result in the voting 
     securities of the Company 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 the Company 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 the 
     Company (or similar transaction) in which no person is or becomes 
     the beneficial owner, directly or indirectly, of securities of 
     the Company representing 25 percent or more of the combined 
     voting power of the Company's then outstanding securities; or 
     (iv) the Company'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 the Company of all or 
     substantially all of the Company's assets, other than a sale or 
     disposition by the Company 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 the Company in substantially the same 
     proportions as their ownership of the Company 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.

10.  Hardship Withdrawal.

          Upon petition to and approval by the Executive Committee, a 
     Participant may withdraw all or a portion of the balance in his 
     Account in the case of financial hardship in the nature of an 
     emergency, provided that the amount of such withdrawal cannot 
     exceed the amount reasonable necessary to meet the financial 
     hardship.  The Executive Committee shall have sole discretion to 
     determine the circumstances under which such withdrawals are 
     permitted.

 11. Amendment and Termination of Plan

          The Plan may be amended, modified or terminated by the 
     Company's Board of Directors.  No amendment, modification, or 
     termination shall adversely affect a Participant's rights with 
     respect to amounts accrued in his Account.  In the event that the 
     Plan is terminated, the Board of Directors has the right to make 
     lump-sum payments of all Account balances on such date as it may 
     determine.

12.  Nonassignability of Plan.

          The right of a Participant to receive any unpaid portion of 
     his Account shall not be assigned, transferred, pledged or 
     encumbered or be subject in any manner to alienation or 
     attachment.

13.  No Creation of Rights.

          Nothing in this Plan shall confer upon any Participant the 
     right to continue as a Director.  The right of a Participant to 
     receive any unpaid portion of his Account shall be an unsecured 
     claim against the general assets and will be subordinated to the 
     general obligations of the Company.

14.  Effective Date.

          The Plan shall become effective on October 15, 1984, and 
     shall remain in effect until it is discontinued by action of the

     effective May 1, 1991, was amended and restated effective 
     February 13, 1996, and was further amended and restated effective 
     May 19, 1998.

exclusive of any other forms of additional Compensation such as the 
Company's cost for any public or private employee benefit plan or any 
income recognized by the Participant as a result of exercising stock 
options.  A Participant's Compensation for any Plan Year shall include 
any 401(k) contributions made by the Participant under Questar 
Corporation's Employee Investment Plan or other tax-qualified plan, 
and any Compensation deferred under the Questar Corporation Deferred 
Share Make-Up Plan.  An Officer's Compensation also shall include the

     "Retired Participant" refers to a Participant who has satisfied

payable to Retired Participant under the terms of the Plan calculated 
as set forth in Section 5 or Section 7.

 3.  EFFECTIVE DATE

     The Plan is effective January 1, 1987.  The Company's 
Equalization Benefit Plan was merged into the Plan effective May 19, 
1998.

 4.  PARTICIPATION IN THE PLAN AND ELIGIBILITY FOR BENEFITS

     Participation in the Plan shall be limited to Participants of the 
Company and Participating Corporations.  To become eligible for 
Supplemental Retirement Benefits under the Plan, a Participant must 
have a vested right to receive benefits under the Retirement Plan.  A 
Retired Participant cannot receive benefits under the Plan during any 
period that his monthly benefits from the Retirement Plan are 
suspended.  

 5.  SUPPLEMENTAL RETIREMENT BENEFITS

     A Participant who satisfies the eligibility requirements 
described above shall be eligible to receive Supplemental Retirement 
Benefits under the Plan.  The first payment of Supplemental Retirement 
Benefits will be due on the first day of the month following 
retirement, and payments will continue on the first day of each month 
thereafter so long as the Retired Participant is alive or so long as 
his/her surviving spouse is entitled to receive monthly benefits under 
the Retirement Plan.  (The Retired Participant's surviving spouse must 
have been married to the Participant at date of his/her retirement.)

     The monthly Supplemental Retirement Benefit shall equal the 
monthly benefit that would have been payable to or on behalf of a 
Retired Participant under the Retirement Plan if the limitation on 
annual benefits imposed by Section 415 of the Code and if the 
limitation on annual compensation as defined in Section 401(a)(17) of 
the Code were not applicable, and if the Retired Participant had not 
voluntarily chosen to defer any compensation under the terms of the 
Questar Corporation Deferred Share Make-Up Plan, less the monthly 
benefits payable from the Retirement Plan and the EIRP (if any).  

     Except as provided in Section 7, the monthly Supplemental 
Retirement Benefit payable to or on behalf of the Retired Participant 
as determined herein shall be paid in the same form as such Retired 
Participant's benefits are payable under the Retirement Plan.  Any 
monthly Supplemental Retirement Benefits payable to the Retired 
Participant's surviving spouse shall be reduced by the monthly 
benefits payable to such surviving spouse under the Retirement Plan 
and the EIRP (if any).

6.   LUMP SUM ELECTION.

     A Participant has a one-time election to receive the present 
value of his Supplemental Retirement Benefit in a lump sum.  The 
Participant shall make this election at least one year prior to 
retirement.  The present value shall be calculated using a standard 
mortality table referred to as the "83 Group Annuity Mortality Table" 
and 80 percent of the six-month average rate for 30-year Treasury bond 
(prior to the Participant's retirement).  When making this election, 
the Participant shall also indicate when the lump-sum payment shall be 
made and if it is to be made in more than one installment.  The full 
amount of any lump-sum payment, together with credited interest, must 
be paid within five years of the Participant's retirement.  Any 
deferred payouts of lump-sum payments shall be credited with interest 
calculated at a monthly rate using the appropriate 30-year Treasury 
bond quoted in the Wall Street Journal on the first business day of 
each month.  (The appropriate 30-year Treasury bond shall be the bond 
that has one closest to maturity date (by month) preceding the date on 
which the interest is to be credited.)  Any lump-sum payments that are 
not deferred shall be paid on the first business day of the month 
following the Participant's retirement date or as soon thereafter as 
is administratively practicable.  If the Participant fails to make an 
election at least one year prior to retirement, the Participant shall 
receive monthly benefits.

     Notwithstanding this provision, a Participant who has not been 
advised that he may receive Supplemental Retirement Benefits and has 
not received an opportunity to make a lump-sum election at least one 
year prior to his retirement shall receive any Supplemental Retirement 
Benefits in one lump-sum payment.  The calculation of this benefit and 
the payment of this benefit shall be made in accordance with the 
provisions of this Section.

 7.  FUNDING

     The Supplemental Retirement Benefits payable under the Plan shall 
be paid by the Company and Participating Corporations out of general 
assets.  In its discretion, the Board may establish a trust fund or 
make other arrangements to assure payment of the Supplemental 
Retirement Benefits. 

 8.  ALLOCATION OF COSTS

     The cost of Supplemental Retirement Benefits paid to or on behalf 
of Retired Participants shall be allocated to and be the 
responsibility of the Company and Participating Corporations.

 9.  ADMINISTRATION

     The Committee shall administer the Plan and may appoint an 
officer of the Company to assist the Committee with this 
responsibility.  The Committee shall have the sole responsibility to 
interpret the Plan and to adopt such rules and regulations for 
carrying out the Plan as it may deem necessary.  Decisions of the 
Committee shall be final and binding.

10.  AMENDMENT OR TERMINATION

     The Board may at any time amend, modify, or terminate this Plan; 
provided, however, that any Retired Participants or their surviving 
spouses receiving Supplemental Retirement Benefits under the Plan at 
the date of amendment or termination shall continue receiving such 
benefits as if such amendment or termination had not occurred and 
provided that any amendment, modification, or termination of the Plan 
shall not adversely affect the right of any Participant to receive 
benefits earned prior to such action.

11.  SUCCESSOR TO THE COMPANY

     The Company shall require any successor or assign, whether direct 
or indirect, by purchase, merger, consolidation or otherwise, to all 
or substantially all of the business and/or assets of the Company, to 
assume and agree to pay any Supplemental Retirement Benefits in the 
same manner and to the same extent that the Company would be required 
to perform if no such succession or assignment had taken place.

12.  CHANGE IN CONTROL AND LEGAL FEES

     The Company shall pay all legal fees and expenses that a Retired 
Participant or a Participant may reasonably incur as a result of the 
Company's contesting the validity or enforceability of such 
participant's right to receive benefits under the terms of this Plan 
following a "Change in Control" of the Company. 

     In the event that a Change in Control of the Company occurs and a 
Participant's employment with the Company or its successor(s) 
terminates, the Participant shall receive a lump-sum payment of his 
Supplemental Retirement Benefits within 30 days of the Participant's 
termination.  Such benefits shall be calculated as set forth in 
Section 6.

     A Change in Control of the Company shall be deemed to have 
occurred if (i) any Acquiring Person (as such term is defined in the 
Rights Agreement dated as of February 13, 1996, between the Company 
and ChaseMellon Shareholder Services L.L.C.) 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 the Company 
representing 25 percent or more of the combined voting power of the 
Company; or (ii) the following individuals cease for any reason to 
constitute a majority of the number of directors then serving:  
individuals who, as of May 19, 1998, constitute the 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 the Company) whose appointment or election by the Board 
or nomination for election by the Company's stockholders was approved 
or recommended by a vote of at least two-thirds (2/3) of the directors 
then still in office who either were directors on May 19, 1998, or 
whose appointment, election or nomination for election was previously 
so approved or recommended; or (iii) the Company's stockholders 
approve a merger or consolidation of the Company or any direct or 
indirect subsidiary of the Company with any other corporation, other 
than a merger or consolidation that would result in the voting 
securities of the Company 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 the Company or such 
surviving entity or any parent thereof outstanding immediately after 
such merger or consolidation, or a merger or consolidation effected to 
implement a recapitalization of the Company (or similar transaction) 
in which no person is or becomes the beneficial owner, directly or 
indirectly, of securities of the Company representing 25 percent or 
more of the combined voting power of the Company's then outstanding 
securities; or (iv) the Company'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 the Company of 
all or substantially all of the Company's assets, other than a sale or 
disposition by the Company 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 the Company in substantially the same proportions as 
their ownership of the Company 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.

5.   Election to Defer Compensation and Deemed Investment.

     (a)  Deferral Election.  In order to participate in the Plan 
during 1989, an Employee must make an election to defer from 2 to 6 
percent of his annual Compensation in excess of the Compensation 
Limit.  For the first Plan Year, which is a partial Plan Year, such 
election must be made at or prior to the effective date of this Plan 
and can only be made as to Compensation to be paid for future 
services.  For all subsequent Plan Years, the election must be made 
prior to the first day of the Plan Year in which it is to become 
effective and can only be made with respect to Compensation to be paid 
for future services.  A deferral election, once made, shall remain in 
effect for subsequent Plan Years until it is revoked or modified by 
the Participant.  A Participant can modify or revoke his deferral 
election with respect to Compensation to be paid for future services 
by submitting a new election or a revocation prior to the beginning of 
the Plan Year in which such new deferral election or revocation is to 
become effective.  All notices of election or revocation shall be made 
on forms prepared by the Company's Secretary and shall be dated, 
signed, and filed with the Company's Secretary.

     (b)  Deemed Investment.  Any amounts deferred by a Participant 
shall be accounted for as if invested in shares of Common Stock 
purchased at a price equal to the average price paid for shares of 
Common Stock purchased by the trustee of the Investment Plan during 
the quarter (prior to January 1, 1996) or month (after such date) in 
which the deferrals are made under this Plan.  This amount shall be 
credited to a Participant's account on a monthly (quarterly prior to 
January 1, 1996) basis.  In addition, a Participant's account shall be 
credited on a quarterly basis with an amount equal to the dividends 
that would have become payable during the deferral period if actual 
purchases of Common Stock had been made, with such dividends accounted 
for as if invested in Common Stock as of the payable date for such 
dividends.  Any credited shares treated as if they were purchased with 
dividends shall be deemed to have been purchased at a price equal to 
the average price of shares purchased with reinvested dividends under 
the Investment Plan during the quarter in which the deemed purchases 
are treated as being made under this Plan.  Each share of Common Stock 
that is deemed to be purchased under this Paragraph 5(b) shall be 
reflected in a Participant's account as a Deferred Share.

6.   Matching Allocations.

     (a)  Amount.  A Participant who makes an election under Section 5 
is entitled to the same Matching Allocations as are made under the 
terms of the Investment Plan.  The Matching Allocations are 100 
percent for the first 2 percent of contributed Compensation; 75 
percent for the second 2 percent; and 50 percent for the last 2 
percent.

     If there are any Excess ESOP Allocations under the Investment 
Plan for a Plan Year, a Participant shall be entitled to an additional 
allocation under this Plan if he is employed by an Employer on the 
last day of such Plan Year or if his employment terminated during such 
Plan Year as a result of an event described in 3.5.1, 3.5.2 or 3.5.3 
of the Investment Plan.  Such additional allocation, or "Excess ESOP 
Allocation," shall be calculated by multiplying the compensation 
deferred by the Participant under the Plan during the Plan Year by the 
same percentage used for the Excess ESOP Allocation in the Investment 
Plan for the comparable year.  Any compensation deferred pursuant to 
this Plan between January 1, 1998 and the effective date of the 
Deferred Share Make-Up Plan that is represented by Deferred Shares 
transferred to such plan shall be excluded from the Compensation 
deferred pursuant to the terms of this Plan for purposes of 
calculating the Excess ESOP Allocation.

     The amount of Matching Allocations shall be accounted for as if 
invested in shares of Common Stock purchased at a price equal to the 
average price paid for shares of Common Stock purchased by the trustee 
of the Investment Plan during the month (quarter prior to January 1, 
1996) in which Matching Allocations are deemed to be made under this 
Plan.  Common Stock deemed to have been purchased with Matching 
Allocations shall be credited to a Participant's account on a monthly 
(quarterly prior to January 1, 1996) basis.  The amount of any Excess 
ESOP Allocations for a Plan Year shall be accounted for as if invested 
in shares of Common Stock purchased at a price equal to the average 
price paid for shares of Common Stock purchased by the trustee of the 
Investment Plan during the last month (quarter prior to January 1, 
1996) of such Plan Year.  Common Stock deemed to have been purchased 
with Excess ESOP Allocations shall be credited to a Participant's 
account as of the last day of the Plan Year to which such Excess ESOP 
Allocations relate.

     In addition, a Participant's account shall be credited on a 
quarterly basis with an amount equal to the dividends that would have 
become payable during the deferral period if actual purchases of 
Common Stock had been made, with such dividends accounted for as if 
invested in Common Stock as of the payable date for such dividends.  
Any credited shares treated as if they were purchased with dividends 
shall be deemed to have been purchased at a price equal to the average 
price paid for shares purchased with reinvested dividends under the 
Investment Plan during the quarter in which the deemed purchases are 
treated as being made under this Plan.  Each share of Common Stock 
that is deemed to be purchased under this Section 6 shall be reflected 
in the Participant's account as a Deferred Share.

     (b)  Vesting.  A Participant shall be vested in the portion of 
his account attributable to Matching Allocations and Excess ESOP 
Allocations to the same extent as such Participant is vested in any 
Matching Allocations and Excess ESOP Allocations credited to his 
account under the Investment Plan.

7.   Transfer of Existing Account Balances, Deferred Share Make-Up 
Plan.

     Any Deferred Shares allocated to a Participant's account balance 
under this Plan prior to June 1, 1998, shall be transferred to the 
Deferred Share Make-Up Plan as of such date to the extent that such 
Deferred Shares are attributable to six percent of Compensation 
deferred in excess of the Compensation Limit and can be segregated 
from any Deferred Shares attributable to six percent of any 
Compensation deferred pursuant to the Company's Deferred Compensation 
Plan.

8.   Statement of Deferred Share Account.

     An annual statement shall be sent to each Participant within 60 
days following the end of each year showing for each preceding Plan 
Year the Compensation deferred, Matching Allocations, Excess ESOP 
Allocations, the total Deferred Shares credited to the Participant's 
account, and the number of these Deferred Shares that are attributable 
to the Participant's deferred Compensation, to Matching Allocations, 
Excess ESOP Allocations, and to reinvested dividends.  Such 
information shall be shown on a monthly (quarterly prior to January 1, 
1996) basis.

9.   Payment of Account Balance.

     (a)  Period of Deferral.  When making the first deferral election 
under Paragraph (a) of Section 5, a Participant shall elect to receive 
all deferred Compensation, Matching Allocations, and Excess ESOP 
Allocations either in a lump-sum payment within 45 days following his 
death, Disability, or termination of employment or in a number of 
annual installments (not to exceed four), the first of which would be 
payable within 45 days following his death, Disability or termination 
of employment with each subsequent payment payable one year 
thereafter.  The account balance shall be valued using the Fair Market 
Value of the Company's Common Stock on the last day of the calendar 
month preceding payment and shall be converted to a cash balance based 
upon such Fair Market Value.  Under an installment payout, the 
Participant's first installment shall be equal to a fraction of the 
balance credited to his account as of the last day of the calendar 
month preceding such payment, the numerator of which is one and the 
denominator of which is the total number of installments selected.  
The amount of each subsequent payment shall be a fraction of the 
balance in the Participant's account as of the last day of the 
calendar month preceding each subsequent payment, the numerator of 
which is one and the denominator of which is the total number of 
installments elected minus the number of installments previously paid.

     (b)  Adverse Tax Determination.  If there is a determination by 
the Internal Revenue Service (IRS) that a Participant should be taxed 
on some or all of the amounts allocated to his account prior to the 
distribution date(s) elected under Paragraph (a) of this Section 9, 
the Participant may elect to have all amounts determined to be 
currently taxable paid to him immediately prior to the time he must 
pay any taxes owed as a result of such IRS determination.

     (c)  Change in Control.  Notwithstanding any other provision of 
this Plan, in the event of a "Change in Control" of the Company, all 
Deferred Shares credited to a Participant's account shall be converted 
to cash equal in amount to the Fair Market Value of the Deferred 
Shares if converted into shares of the Company's Common Stock.  The 
cash shall be distributed to him within 60 days following the Change 
in Control.  The account balance shall be valued using the Fair Market 
Value of the Company's Common Stock on the last day of the calendar 
month preceding payment.

     A Change in Control of the Company shall be deemed to have 
occurred if (i) any "Acquiring Person" (as such term is defined in the 
Rights Agreement dated as of February 13, 1996, between the Company 
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 the 
Company representing 25 percent or more of the combined voting power 
of the Company; or (ii) the following individuals cease for any reason 
to constitute a majority of the number of directors then serving:  
individuals who, as of May 19, 1998, constitute the Company'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 the Company) 
whose appointment or election by the Board or nomination for election 
by the Company's stockholders was approved or recommended by a vote of 
at least two-thirds of the directors then still in office who either 
were directors on May 19, 1998, or whose appointment, election or 
nomination for election was previously so approved or recommended; or 
(iii) the Company's stockholders approve a merger or consolidation of 
the Company or any direct or indirect subsidiary of the Company with 
any other corporation, other than a merger or consolidation that would 
result in the voting securities of the Company 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 the Company 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 the Company (or similar transaction) 
in which no person is or becomes the beneficial owner, directly or 
indirectly, of securities of the Company representing 25 percent or 
more of the combined voting power of the Company's then outstanding 
securities; or (iv) the Company'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 the Company of 
all or substantially all of the Company's assets, other than a sale or 
disposition by the Company 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 the Company in substantially the same proportions as 
their ownership of the Company 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.

     (d)  Method of Payment.  All amounts credited to a Participant's 
account shall be distributed to him or, in the event of his death, to 
his Beneficiary, in cash and in accordance with the election made by 
the Participant.  

     (e)  Source of Payments.  Each participating Employer will pay 
all benefits for its Employees arising under this Plan, out of its 
general assets.

10.  Amendment and Termination of Plan.

     The Plan may be amended, modified or terminated by the Company's 
Board of Directors at any time; provided, however, no such amendment, 
modification or termination shall be made in the event there is a 
Change in Control, as defined in Paragraph (c) of Section 9.  In 
addition, no amendment, modification, or termination shall reduce any 
deferred benefit under the Plan reflected in a Participant's account 
prior to the date of such amendment or termination.  

11.  Non-assignability of Benefits.

     To the extent consistent with applicable law, the Participant's 
deferred benefits under this Plan shall not be assigned, transferred, 
pledged, or encumbered or be subject in any manner to alienation or 
attachment.

12.  No Creation of Rights.

     Nothing in this Plan shall confer upon any Participant the right 
to continue as an Employee or to receive annual Compensation in excess 
of the Compensation Limit.  The right of a Participant to receive a 
cash distribution shall be an unsecured claim against the general 
assets of his Employer.  Nothing contained in this Plan nor any action 
taken hereunder shall create, or be construed to create, a trust of 
any kind, or a fiduciary relationship between the Company and the 
Participants, Beneficiaries, or any other persons.  All accounts under 
the Plan shall be maintained for bookkeeping purposes only and shall 
not represent a claim against specific assets of any Employer.

13.  Effective Date.

     The Plan, as originally adopted, was effective on July 1, 1989.  
The Plan, as most recently amended and restated, is effective May 19, 
1998, and shall remain in effect until it is discontinued by action of 
the Company's Board of Directors.

5.   Transfer of Account Balances, Deferred Share Plan.

     Any Deferred Shares allocated to an Employee's account balance 
under the Deferred Share Plan prior to June 1, 1998, shall be

deferred in excess of the Compensation Limit and can be segregated 
from any Deferred Shares attributable to six percent of any 
Compensation deferred pursuant to the Company's Deferred Compensation 
Plan.

6.   Election to Defer Compensation and Deemed Investment.

     (a)  Deferral Election.  Any Employee who has previously made an 
election to defer Compensation for purposes of the Deferred Share Plan 
shall automatically become a Participant in this Plan for 1998 and 
subsequent years at such time that his/her Compensation exceeds the 
Compensation Ceiling.  A deferral election, once made, shall remain in 
effect for subsequent Plan Years until it is revoked or modified by 
the Participant.  A Participant can modify or revoke his/her deferral 
election with respect to Compensation to be paid for future services 
by submitting a new election or a revocation prior to the beginning of 
the Plan Year in which such new deferral election or revocation is to 
become effective.  All notices of election or revocation shall be made 
on forms prepared by the Company's Secretary and shall be dated, 
signed, and filed with the Company's Secretary.

     (b)  Deemed Investment.  Any amounts deferred by a Participant 
shall be accounted for as if invested in shares of Common Stock 
purchased at a price equal to the average price paid for shares of 
Common Stock purchased by the trustee of the Investment Plan during 
month in which the deferrals are made under this Plan.  This amount 
shall be credited to a Participant's account on a monthly basis.  In 
addition, a Participant's account shall be credited on a quarterly 
basis with an amount equal to the dividends that would have become 
payable during the deferral period if actual purchases of Common Stock 
had been made, with such dividends accounted for as if invested in 
Common Stock as of the payable date for such dividends.  Any credited 
shares treated as if they were purchased with dividends shall be 
deemed to have been purchased at a price equal to the average price of 
shares purchased with reinvested dividends under the Investment Plan 
during the quarter in which the deemed purchases are treated as being 
made under this Plan.  Each share of Common Stock that is deemed to be 
purchased under this Paragraph 6(b) shall be reflected in a 
Participant's account as a Deferred Share.

7.   Matching Allocations.

     (a)  Amount.  A Participant who makes an election under Section 6 
is entitled to the same Matching Allocations as are made under the 
terms of the Investment Plan.  The Matching Allocations are 100 
percent for the first 2 percent of contributed Compensation; 75 
percent for the second 2 percent; and 50 percent for the last 2 
percent.

     If there are any Excess ESOP Allocations under the Investment 
Plan for a Plan Year, a Participant shall be entitled to an additional 
allocation under this Plan if he is employed by an Employer on the 
last day of such Plan Year or if his employment terminated during such 
Plan Year as a result of an event described in 3.5.1, 3.5.2 or 3.5.3 
of the Investment Plan.  Such additional allocation shall be 
calculated by multiplying the Compensation deferred by the Participant 
under the Plan during the Plan Year by the same percentage used for 
the Excess ESOP Allocation in the Investment Plan for the comparable 
year.  Any Compensation deferred pursuant to the Deferred Share Plan 
between January 1, 1998 and the effective date of this Plan that is 
represented by Deferred Shares transferred to this Plan shall be 
included in Compensation deferred pursuant to the terms of this Plan 
for purposes of calculating the Excess ESOP Allocation.

     The amount of Matching Allocations shall be accounted for as if 
invested in shares of Common Stock purchased at a price equal to the 
average price paid for shares of Common Stock purchased by the trustee 
of the Investment Plan during the month in which Matching Allocations 
are deemed to be made under this Plan.  Common Stock deemed to have 
been purchased with Matching Allocations shall be credited to a 
Participant's account on a monthly basis.  The amount of any Excess 
ESOP Allocations for a Plan Year shall be accounted for as if invested 
in shares of Common Stock purchased at a price equal to the average 
price paid for shares of Common Stock purchased by the trustee of the 
Investment Plan during the last month of such Plan Year.  Common Stock 
deemed to have been purchased with Excess ESOP Allocations shall be 
credited to a Participant's account as of the last day of the Plan 
Year to which such Excess ESOP Allocations relate. 

     In addition, a Participant's account shall be credited on a 
quarterly basis with an amount equal to the dividends that would have 
become payable during the deferral period if actual purchases of 
Common Stock had been made, with such dividends accounted for as if 
invested in Common Stock as of the payable date for such dividends.  
Any credited shares treated as if they were purchased with dividends 
shall be deemed to have been purchased at a price equal to the average 
price paid for shares purchased with reinvested dividends under the 
Investment Plan during the quarter in which the deemed purchases are 
treated as being made under this Plan.  Each share of Common Stock 
that is deemed to be purchased under this Section 7 shall be reflected 
in the Participant's account as a Deferred Share.

     (b)  Vesting.  A Participant shall be vested in the portion of 
his account attributable to Matching Allocations and Excess ESOP 
Allocations to the same extent as such Participant is vested in any 
Matching Allocations and Excess ESOP Allocations credited to his 
account under the Investment Plan.

8.   Statement of Deferred Share Account.

     An annual statement shall be sent to each Participant within 60 
days following the end of each year showing for each preceding Plan 
Year the Compensation deferred, Matching Allocations, Excess ESOP 
Allocations, the total Deferred Shares credited to the Participant's 
account, and the number of these Deferred Shares that are attributable 
to the Participant's deferred Compensation, to Matching Allocations, 
Excess ESOP Allocations, and to reinvested dividends.  Such 
information shall be shown on a monthly basis.

9.   Payment of Account Balance.

     (a)  Period of Deferral.  The Participant's prior deferral 
election(s) for the Deferred Share Plan shall be applicable to this 
Plan for any amounts transferred to this Plan.  When making a first 
deferral election under Paragraph (a) of Section 6, a Participant 
shall elect to receive all deferred Compensation, Matching 
Allocations, and Excess ESOP Allocations either in a lump-sum payment 
within 45 days following his death, Disability, or termination of 
employment or in a number of annual installments (not to exceed four), 
the first of which would be payable within 45 days following his 
death, Disability or termination of employment with each subsequent 
payment payable one year thereafter.  The account balance shall be 
valued using the Fair Market Value of the Company's Common Stock on 
the last day of the calendar month preceding payment and shall be 
converted to a cash balance based upon such Fair Market Value.  Under 
an installment payout, the Participant's first installment shall be 
equal to a fraction of the balance credited to his account as of the 
last day of the calendar month preceding such payment, the numerator 
of which is one and the denominator of which is the total number of 
installments selected.  The amount of each subsequent payment shall be 
a fraction of the balance in the Participant's account as of the last 
day of the calendar month preceding each subsequent payment, the 
numerator of which is one and the denominator of which is the total 
number of installments elected minus the number of installments 
previously paid.

     (b)  Adverse Tax Determination.  If there is a determination by 
the Internal Revenue Service (IRS) that a Participant should be taxed 
on some or all of the amounts allocated to his account prior to the 
distribution date(s) elected under Paragraph (a) of this Section 9, 
the Participant may elect to have all amounts determined to be 
currently taxable paid to him immediately prior to the time he must 
pay any taxes owed as a result of such IRS determination.

     (c)  Change in Control.  Notwithstanding any other provision of 
this Plan, in the event of a "Change in Control" of the Company, all 
Deferred Shares credited to a Participant's account shall be converted 
to cash equal in amount to the Fair Market Value of the Deferred 
Shares if converted into shares of the Company's Common Stock.  The 
cash shall be distributed to him within 60 days following the Change 
in Control.  The account balance shall be valued using the Fair Market 
Value of the Company's Common Stock on the last day of the calendar 
month preceding payment.

     A "Change in Control" of the Company shall be deemed to have 
occurred if (i) any "Acquiring Person" (as such term is defined in the 
Rights Agreement dated as of February 13, 1996, between the Company 
and ChaseMellon Shareholder Services L.L.C.) 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 the Company 
representing 20 percent or more of the combined voting power of the 
Company; or (ii) the following individuals cease for any reason to 
constitute a majority of the number of directors then serving:  
individuals who, as of May 19, 1998, constitute the Company'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 the Company) 
whose appointment or election by the Board or nomination for election 
by the Company's stockholders was approved or recommended by a vote of 
at least two-thirds (2/3) of the directors then still in office who 
either were directors on May 19, 1998, or whose appointment, election 
or nomination for election was previously so approved or recommended; 
or (iii) the Company's stockholders approve a merger or consolidation 
of the Company or any direct or indirect subsidiary of the Company 
with any other corporation, other than a merger or consolidation that 
would result in the voting securities of the Company 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 the 
Company or such surviving entity or any parent thereof outstanding 
immediately after such merger or consolidation, or a merger or 
consolidation effected to implement a recapitalization of the Company 
(or similar transaction) in which no person is or becomes the 
beneficial owner, directly or indirectly, of securities of the Company 
representing 25 percent or more of the combined voting power of the 
Company's then outstanding securities; or (iv) the Company'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 the Company of all or substantially all of the 
Company's assets, other than a sale or disposition by the Company 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 the Company in substantially the 
same proportions as their ownership of the Company 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.

     (d)  Method of Payment.  All amounts credited to a Participant's 
account shall be distributed to him or, in the event of his death, to 
his Beneficiary, in cash and in accordance with the election made by 
the Participant.  

     (e)  Source of Payments.  Each participating Employer will pay 
all benefits for its Employees arising under this Plan.

10.  Amendment and Termination of Plan.

     The Plan may be amended, modified or terminated by the Company's 
Board of Directors at any time; provided, however, no such amendment, 
modification or termination shall be made in the event there is a 
Change in Control, as defined in Paragraph (c) of Section 9.  In 
addition, no amendment, modification, or termination shall reduce any 
deferred benefit under the Plan reflected in a Participant's account 
prior to the date of such amendment or termination.  

11.  Non-assignability of Benefits.

     To the extent consistent with applicable law, the Participant's 
deferred benefits under this Plan shall not be assigned, transferred, 
pledged, or encumbered or be subject in any manner to alienation or 
attachment.

12.  No Creation of Rights.

     Nothing in this Plan shall confer upon any Participant the right 
to continue as an Employee or to receive annual Compensation in excess 
of the Compensation Limit.  The right of a Participant to receive a 
cash distribution shall be an unsecured claim against the general 
assets of his Employer.  Nothing contained in this Plan nor any action 
taken hereunder shall create, or be construed to create, a trust of 
any kind, or a fiduciary relationship between the Company and the 
Participants, Beneficiaries, or any other persons.  All accounts under 
the Plan shall be maintained for bookkeeping purposes only and shall 
not represent a claim against specific assets of any Employer.

13.  Effective Date.

     The Plan is adopted effective on May 19, 1998, and shall remain 
in effect until it is discontinued by action of the Company's Board of 
Directors.

 3.  EFFECTIVE DATE

     The Plan is effective May 19, 1998.  Some provisions in this Plan 
were formerly included in the Company's SERP.

 4.  PARTICIPATION IN THE PLAN AND ELIGIBILITY FOR BENEFITS

     Participation in the Plan shall be limited to highly compensated 
employees of the Company and Participating Corporations who are 
eligible to defer compensation pursuant to the Company's Deferred 
Compensation Plan.  To become eligible for Supplemental Retirement 
Benefits and Special Supplemental Retirement Benefits under the Plan, 
a Participant must have a vested right to receive benefits under the 
Retirement Plan.  A Retired Participant cannot receive benefits under 
the Plan during any period that his monthly benefits from the 
Retirement Plan are suspended.  

 5.  SUPPLEMENTAL RETIREMENT BENEFITS

     A Participant who satisfies the eligibility requirements 
described above shall be eligible to receive Supplemental Retirement 
Benefits under the Plan.  The first payment of Supplemental Retirement 
Benefits will be due on the first day of the month following 
retirement, and payments will continue on the first day of each month 
thereafter so long as the Retired Participant is alive or so long as 
his surviving spouse is entitled to receive monthly benefits under the 
Retirement Plan.  (The Retired Participant's surviving spouse must 
have been married to the Participant at date of such Participant's 
retirement.)

     The monthly Supplemental Retirement Benefit shall equal the 
monthly benefit that would have been payable to or on behalf of a 
Retired Participant under the Retirement Plan if the limitation on 
annual benefits imposed by Section 415 of the Code and if the 
limitation on annual compensation as defined in Section 401(a)(17) of 
the Code were not applicable, and if the Retired Participant had not 
voluntarily chosen to defer any compensation under the terms of the 
Questar Corporation Deferred Compensation Plan and the Questar 
Corporation Deferred Share Plan, less the monthly benefits payable 
from the Retirement Plan, the EIRP (if any), and the SERP (if any).  
The monthly Supplemental Retirement Benefit of a Special Situation 
Officer shall be calculated using the years of service credited to him 
for purposes of calculating the Special Supplemental Retirement 
Benefits as provided in Section 6.

     Except as provided in Section 7, the monthly Supplemental 
Retirement Benefit  payable to or on behalf of the Retired Participant 
as determined herein shall be paid in the same form as such Retired 
Participant's benefits are payable under the Retirement Plan.  Any 
monthly Supplemental Retirement Benefits payable to the Retired 
Participant's surviving spouse shall be reduced by the monthly 
benefits payable to such surviving spouse under the Retirement Plan, 
the EIRP (if any), and the Supplemental Executive Retirement Plan.

 6.  SPECIAL SUPPLEMENTAL RETIREMENT BENEFITS.

     A Special Situation Officer shall be eligible to receive Special 
Supplemental Retirement Benefits under the Plan.

     The Special Supplemental Retirement Benefit is designed to 
provide a Special Situation Officer with a supplemental retirement 
benefit that is equal to the difference between the monthly Retirement 
Plan benefit that he would have received if his years of service prior 
to his break in service could be credited to him for purposes of 
calculating his benefit under the Retirement Plan and the monthly 
Retirement Plan benefit that he is entitled to receive because he 
cannot be given credit for such years of service under the Retirement 
Plan.

     The first payment of Special Supplemental Retirement Benefits 
will be due on the first day of the month following retirement and 
payments will continue on the first day of each month thereafter so 
long as the Special Situation Officer is alive or so long as his 
surviving spouse is entitled to receive monthly benefits under the 
Retirement Plan.  (The surviving spouse must have been married to the 
Special Situation Officer at date of such Officer's retirement.)

     The monthly benefit payable under this Section is not offset by 
any monthly benefit payable under the EIRP or SERP.  Except as 
provided in Section 7, the monthly benefit payable to the Special 
Situation Officer upon his retirement shall be paid in the same form 
as his benefits under the Retirement Plan.

7.   LUMP SUM ELECTION.

     A Participant has a one-time election to receive the present 
value of his Supplemental Retirement Benefit and Special Supplemental 
Retirement Benefit (if applicable) in a lump sum.  The Participant 
shall make this election at least one year prior to retirement.  The 
present value shall be calculated using a standard mortality table 
referred to as the "83 Group Annuity Mortality Table" and 80 percent 
of the six-month average rate for 30-year Treasury bond (prior to the 
Participant's retirement).  When making this election, the Participant 
shall also indicate when the lump-sum payment shall be made and if it 
is to be made in more than one installment.  The full amount of any 
lump-sum payment, together with credited interest, must be paid within 
five years of the Participant's retirement.  Any deferred payouts of 
lump-sum payments shall be credited with interest calculated at a 
monthly rate using the appropriate 30-year Treasury bond quoted in the 
Wall Street Journal on the first business day of each month.  (The 
appropriate 30-year Treasury bond shall be the bond that has one 
closest to maturity date (by month) preceding the date on which the 
interest is to be credited.)  Any lump-sum payments that are not 
deferred shall be paid on the first business day of the month 
following the Participant's retirement date or as soon thereafter as 
is administratively practicable.  The Participant's spouse must 
consent to the Participant's election to receive a lump-sum payment.  
Such consent must be in writing and must acknowledge the effect of 
such election. 

     If the Participant fails to make an election at least one year 
prior to retirement, the Participant shall receive monthly benefits.

 8.  FUNDING

     The Supplemental Retirement Benefits and Special Supplemental 
Retirement Benefits payable under the Plan shall be paid by the 
Company and Participating Corporations out of general assets.  In its 
discretion, the Board may establish a trust fund or make other 
arrangements to assure payment of the Supplemental Retirement Benefits 
and Special Supplemental Retirement Benefits. 

 9.  ALLOCATION OF COSTS

     The cost of Supplemental Retirement Benefits and Special 
Supplemental Retirement Benefits paid to or on behalf of Retired 
Participants shall be allocated to and be the responsibility of the 
Company and Participating Corporations.

10.  ADMINISTRATION

     The Committee shall administer the Plan and may appoint an 
officer of the Company to assist the Committee with this 
responsibility.  The Committee shall have the sole responsibility to 
interpret the Plan and to adopt such rules and regulations for 
carrying out the Plan as it may deem necessary.  Decisions of the 
Committee shall be final and binding.

11.  AMENDMENT OR TERMINATION

     The Board may at any time amend, modify, or terminate this Plan; 
provided, however, that any Retired Participants or their surviving 
spouses receiving Supplemental Retirement Benefits and Special 
Supplemental Retirement Benefits under the Plan at the date of 
amendment or termination shall continue receiving such benefits as if 
such amendment or termination had not occurred and provided that any 
amendment, modification, or termination of the Plan shall not 
adversely affect the right of any Participant to receive benefits 
earned prior to such action.

12.  SUCCESSOR TO THE COMPANY

     The Company shall require any successor or assign, whether direct 
or indirect, by purchase, merger, consolidation or otherwise, to all 
or substantially all of the business and/or assets of the Company, to 
assume and agree to pay any Supplemental Retirement Benefits and 
Special Supplemental Retirement Benefits in the same manner and to the 
same extent that the Company would be required to perform if no such 
succession or assignment had taken place.

13.  CHANGE IN CONTROL AND LEGAL FEES

     The Company shall pay all legal fees and expenses that a Retired 
Participant or a Participant may reasonably incur as a result of the 
Company's contesting the validity or enforceability of such person's 
right to receive benefits under the terms of this Plan following a 
"Change in Control" of the Company. 

     In the event that a Change in Control of the Company occurs and a 
Participant's employment with the Company terminates, the Participant 
shall receive a lump-sum payment of his Supplemental Retirement 
Benefits and Special Situation Retirement Benefits within 30 days of 
the Participant's termination.  Such benefits shall be calculated as 
set forth in Section 7.

     A Change in Control of the Company shall be deemed to have 
occurred if (i) any "Acquiring Person" (as such term is defined in the 
Rights Agreement dated as of February 13, 1996, between the Company 
and ChaseMellon Shareholder Services L.L.C.) 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 the Company 
representing 25 percent or more of the combined voting power of the 
Company; or (ii) the following individuals cease for any reason to 
constitute a majority of the number of directors then serving:  
individuals who, as of May 19, 1998, constitute the 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 the Company) whose appointment or election by the Board 
or nomination for election by the Company's stockholders was approved 
or recommended by a vote of at least two-thirds (2/3) of the directors 
then still in office who either were directors on May 19, 1998, or 
whose appointment, election or nomination for election was previously 
so approved or recommended; or (iii) the Company's stockholders 
approve a merger or consolidation of the Company or any direct or 
indirect subsidiary of the Company with any other corporation, other 
than a merger or consolidation that would result in the voting 
securities of the Company 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 the Company or such 
surviving entity or any parent thereof outstanding immediately after 
such merger or consolidation, or a merger or consolidation effected to 
implement a recapitalization of the Company (or similar transaction) 
in which no person is or becomes the beneficial owner, directly or 
indirectly, of securities of the Company representing 25 percent or 
more of the combined voting power of the Company's then outstanding 
securities; or (iv) the Company'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 the Company of 
all or substantially all of the Company's assets, other than a sale or 
disposition by the Company 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 the Company in substantially the same proportions as 
their ownership of the Company 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.


                      QUESTAR CORPORATION
                  DEFERRED COMPENSATION PLAN
               FOR HIGHLY COMPENSATED EMPLOYEES

     Questar Corporation hereby amends this DEFERRED COMPENSATION PLAN 
FOR HIGHLY COMPENSATED EMPLOYEES, effective February 13, 1996.  This

recognized by the employee as a result of exercising stock options.  
An Employee's Compensation for any Plan Year shall include any

Compensation for a Plan Year agreed upon under one or more 
Compensation reduction agreements entered into pursuant to the Questar 
Corporation Cafeteria Plan.

     "Disability" means a condition that renders a Participant unable 
to engage in any substantial gainful activity by reason of any 
medically determinable physical or

annual Compensation in order to reduce current tax payment 
obligations.

3.   Administration.

     The Management Performance Committee of the Company's Board of 
Directors shall construe and administer the Plan and shall have full 
authority to make such rules and regulations deemed necessary or 
desirable to carry out such administration. The Management Performance 
Committee may appoint an officer or department to assist with the

Participants, Beneficiaries and Employers.

4.   Eligibility.

     All officers and any key manager whose annual Compensation is 
expected to exceed $125,000 are eligible to participate in the Plan.

5.   Election to Defer Compensation.

     In order to participate in the Plan during 1993, an Employee must 
make an election to defer at least $500 per month of participation.  
For the first Plan Year, which is a partial Plan Year, such election 
must be made at or prior to the effective date of this Plan and can 
only be made as to Compensation to be paid for future services.  In 
order to participate in subsequent Plan Years, an Employee must make 
an election to defer an amount from $5,000 to 50 percent of annual 
Compensation.  Such elections must be made prior to the first day of 
the Plan Year in which it is to become effective and can only be made 
with respect to Compensation to be paid for future services.  A 
deferral election, once made, shall remain in effect for subsequent 
Plan Years until it is revoked or modified by the Participant.  A 
Participant can modify or revoke his deferral election with respect to 
Compensation to be paid for future services by submitting a new 
election or a revocation prior to the beginning of the Plan Year in 
which such new deferral election or revocation is to become effective.  
All notices of election or revocation shall be made on forms prepared 
by the Company's Secretary and shall be dated, signed, and filed with 
the Company's Secretary.

6.   Elections, Deemed Investments.

     When making an election to defer Compensation, an Employee must 
choose between two methods of determining earnings on the deferred 
Compensation.  He may choose to have such earnings calculated as if 
the deferred Compensation had been invested in shares of the Company's 
Common Stock (the "Common Stock Option") or he may choose to have 
earnings calculated by adding 100 basis points to the interest payable 
on a 10-Year Treasury Note (the "Treasury Note Option").  An Employee 
may also choose to allocate his deferred Compensation between the 
options in increments of 25 percent, 50 percent, or 75 percent.

     The Participant must designate his deemed investment for all of 
the Compensation he elects to defer in any given year.  He may change 
the deemed investment for future deferred Compensation by filing the 
appropriate notice with the Company's Corporate Secretary before the 
first day of each calendar year, but such change shall not affect the 
method of determining earnings of any Compensation deferred in a prior 
year.

     Any deferred Compensation accounted for under the Common Stock 
Option  shall be accounted for as if invested in shares of Common 
Stock purchased at a price equal to the average price paid for shares 
of Common Stock purchased by the trustee of the Tax-Qualified Plan 
during the month (quarter prior to January 1, 1996) in which the 
deferrals are made under this Plan.  This amount shall be credited to 
a Participant's account on a monthly (quarterly prior to January 1, 
1996) basis.  In addition, a Participant's account shall be credited 
on a quarterly basis with an amount equal to the dividends that would 
have become payable during the deferral period if actual purchases of 
Common Stock had been made, with such dividends accounted for as if 
invested in Common Stock as of the payable date for such dividends.  
Any credited shares treated as if they were purchased with dividends 
shall be deemed to have been purchased at a price equal to the average 
price of shares purchased with reinvested dividends under the 
Tax-Qualified Plan during the quarter in which the deemed purchases 
are treated as being made under this Plan.

     If a Participant elects the Treasury Note Option, his account 
will be credited with any Compensation deferred by the Participant in 
any given month.  Interest shall be calculated at a monthly rate 
calculated by dividing by 12 the sum of 100 basis points plus the rate 
for the appropriate 10-Year Treasury Note as quoted in the Wall Street 
Journal on the first business day of each month.  The appropriate 
10-Year Treasury Note shall be the Note that is the closest (in terms 
of months) to the date on which the interest is credited.  The 
interest deemed to be credited to each Account shall be based on the 
amount credited to such Account at the beginning of each particular 
month.

7.   Integration with Other Plans.

     If an employee elects to reduce his Compensation under the terms 
of this Plan, six percent of any Compensation deferred shall be 
accounted for under the terms of the Questar Corporation Deferred 
Share Plan.  A Participant's benefits (if any) under the Company's 
Executive Incentive Retirement Plan shall be based on the 
Participant's base salary including any base salary deferred under the 
terms of this Plan or the Company's Deferred Share Plan or any base 
salary reductions under the Company's Tax-Qualified Plan or Cafeteria 
Plan.  A Participant's benefits (if any) under the Company's 
Supplemental Executive Retirement Plan or Equalization Benefit Plan 
shall be based on the Participant's Compensation plus any Compensation 
deferred under the terms of this Plan or the Company's Deferred Share 
Plan.

8.   Account Statement.

     Within 60 days after the end of the calendar year, a statement 
shall be sent to each Participant listing the balance in his account 
as of the end of the year.

9.   Payment of Account Balances.

     When making the first deferral election under Paragraph 5, a 
Participant shall determine when to receive the Compensation deferred 
by him.  A Participant can elect to receive such deferred Compensation 
at a specified date prior to his termination of employment, e.g., 
December 31, 2001, upon his termination of employment or at a 
specified time within five years after his termination of employment.  
A Participant can also elect whether to receive deferred Compensation 
in a lump-sum payment or in a number of annual installments (not to 
exceed four).  A Participant cannot change such elections for 
Compensation previously deferred, but can change such elections for 
Compensation to be paid for future services.

     Under the Common Stock Option, the account balance shall be 
valued using the Fair Market Value of the Company's Common Stock on 
the last day of the calendar month preceding payment and shall be 
converted to a cash balance based upon such Fair Market Value.  Under 
an installment payout, the Participant's first installment shall be 
equal to a fraction of the balance credited to his account (or the 
portion of his account to be paid in installments) as of the last day 
of the calendar month preceding such payment, the numerator of which 
is one and the denominator of which is the total number of 
installments selected.  The amount of each subsequent payment shall be 
a fraction of the balance in the Participant's account as of the last 
day of the calendar month preceding each subsequent payment, the 
numerator of which is one and the denominator of which is the total 
number of installments elected minus the number of installments 
previously paid.

     Under the Treasury Note Option, the account balance shall be 
valued as of the date of withdrawal, which is the last day of the 
calendar month preceding payment, with interest credited to such date.  
Under an installment payout, the Participant's first installment shall 
be equal to a fraction of the balance credited to his account (or the 
portion of his account to be paid in installments) as of the last day 
of the calendar month preceding such payment, the numerator of which 
is one and the denominator of which is the total number of 
installments selected.  The amount of each subsequent payment shall be 
a fraction of the balance in the Participant's account as of the last 
day of the calendar month preceding each subsequent payment, the 
numerator of which is one and the denominator of which is the total 
number of installments elected minus the number of installments 
previously paid.

10.  Miscellaneous Payment Issues.

     (a)  Adverse Tax Determination.  If there is a determination by 
the Internal Revenue Service (IRS) that a Participant should be taxed 
on some or all of the amounts allocated to his account prior to the 
distribution date(s) elected under Paragraph 9, the Participant may 
elect to have all amounts determined to be currently taxable paid to 
him immediately prior to the time he must pay any taxes owed as a 
result of such IRS determination.

     (b)  Change in Control.  Notwithstanding any other provision of 
this Plan, in the event of a "Change in Control" of the Company (as 
defined below), all deferred Compensation credtired to a Participant's 
account shall be distributed to him within 60 days following the 
Change in Control.

     A Change in Control of the Company shall be deemed to have 
occurred if (i) any "Acquiring Person" (as such term is defined in the 
Rights Agreement dated as of February 13, 1996, between the Company 
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 the 
Company representing 25 percent or more of the combined voting power 
of the Company; or (ii) the following individuals cease for any reason 
to constitute a majority of the number of directors then serving:  
individuals who, as of May 19, 1998, constitute the Company'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 the Company) 
whose appointment or election by the Board or nomination for election 
by the Company's stockholders was approved or recommended by a vote of 
at least two-thirds of the directors then still in office who either 
were directors on May 19, 1998, or whose appointment, election or 
nomination for election was previously so approved or recommended; or 
(iii) the Company's stockholders approve a merger or consolidation of 
the Company or any direct or indirect subsidiary of the Company with 
any other corporation, other than a merger or consolidation that would 
result in the voting securities of the Company 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 the Company 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 the Company (or similar transaction) 
in which no person is or becomes the beneficial owner, directly or 
indirectly, of securities of the Company representing 25 percent or 
more of the combined voting power of the Company's then outstanding 
securities; or (iv) the Company'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 the Company of 
all or substantially all of the Company's assets, other than a sale or 
disposition by the Company 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 the Company in substantially the same proportions as 
their ownership of the Company 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.

     (c)  Method of Payment.  All amounts credited to a Participant's 
account shall be distributed to him or, in the event of his death, to 
his Beneficiary, in cash and in accordance with the election made by 
the Participant.  

     (d)  Source of Payments.  Each participating Employer will pay 
all benefits for its Employees arising under this Plan, and all costs, 
charges and expenses relating thereto, out of its general assets.

11.  Amendment and Termination of Plan.

     The Plan may be amended, modified or terminated by the Company's 
Board of Directors at any time.  Provided, however, no such amendment, 
modification or termination shall be made in the event there is a 
Change in Control, as defined in Paragraph 10(b).  In addition, no 
amendment, modification, or termination shall reduce any deferred 
benefit under the Plan reflected in a Participant's account prior to 
the date of such amendment or termination.  

12.  Non-assignability of Benefits.

     To the extent consistent with applicable law, the Participant's 
deferred benefits under this Plan shall not be assigned, transferred, 
pledged, or encumbered or be subject in any manner to alienation or 
attachment.

13.  No Creation of Rights.

     Nothing in this Plan shall confer upon any Participant the right 
to continue as an Employee of an Employer.  The right of a Participant 
to receive a cash distribution shall be an unsecured claim against the 
general assets of his Employer.  Nothing contained in this Plan nor 
any action taken hereunder shall create, or be construed to create, a 
trust of any kind, or a fiduciary relationship between the Company and 
the Participants, Beneficiaries, or any other persons.  All accounts 
under the Plan shall be maintained for bookkeeping purposes only and 
shall not represent a claim against specific assets of any Employer.  

14.  Effective Date.

     The Plan, as originally adopted, was effective November 1, 1993.  
The Plan, as amended and restated, is effective February 13, 1996, and 
shall remain in effect until it is discontinued by action of the 
Company's Board of Directors.
