INDEMNIFICATION AGREEMENT

This Agreement, effective ________________, between Questar Corporation, a Utah
corporation (the “Company”), and _______________ (the “Director”).
WHEREAS, the Director has agreed to serve as a director of the Company and in
that capacity will perform a valuable service for the Company;
WHEREAS, both the Company and the Director recognize the increased risk of
litigation and other claims being asserted against directors of public companies
in today’s business environment;
WHEREAS, the Bylaws of the Company require the Company to indemnify its
directors and the Director has agreed to serve as a director of the Company in
part in reliance on such Bylaws;
WHEREAS, costs, limits in coverage and availability of directors’ and officers’
liability insurance policies and developments in the application, amendment and
enforcement of statutory and bylaw indemnification provisions generally have
raised questions concerning the adequacy and reliability of the protection
afforded to directors and have increased the difficulty of attracting and
retaining qualified persons to serve as directors;
WHEREAS, to provide the Director with protection against personal liability, to
enhance the Director’s service to the Company in an effective manner, and to
provide the Director with specific contractual assurance that the protection
promised by the Bylaws will be available to the Director (regardless of, among
other things, any amendment to or revocation of the Bylaws or any change in the
composition of the Company’s Board of Directors or any acquisition transaction
relating to the Company), the Company wishes to provide in this Agreement for
the indemnification of, and the advancing of expenses to, the Director to the
full extent (whether partial or complete) permitted by law and as set forth in
this Agreement.

--------------------------------------------------------------------------------

NOW, THEREFORE, in consideration of the foregoing and the covenants contained
herein, and intending to be legally bound hereby, the Company and the Director
do hereby agree as follows:
1.    Definitions. As used in this Agreement:
(a)    The term “Proceeding” shall include any threatened, pending or completed
claim, action, suit or proceeding or any inquiry or investigation, whether
brought by or in the right of the Company or otherwise, whether of a civil,
criminal, administrative or investigative nature, whether of a formal or
informal nature, and in which the Director was, is, or is threatened to be
involved as a party or otherwise, by reason of the fact that he is or was a
Director of the Company or any of its affiliates; or by reason of the fact that
he is or was serving at the request of the Company as a director, officer,
employee, or agent of another corporation, partnership, joint venture, trust, or
other enterprise; or by reason of any action taken by him or any inaction on his
part while acting in any such capacity, in each case whether or not he is acting
or serving in any such capacity at the time any liability or expense is incurred
for which indemnification or reimbursement can be provided under this Agreement.
(b)    The term “Expense” shall include, without limitation, expenses of
investigations, judicial or administrative proceedings or appeals, judgments,
fines and penalties, amounts paid in settlement by the Director, attorneys’ fees
(including fees and expenses of counsel selected by the Director) and
disbursements, and any expenses of establishing a right to indemnification under
Paragraph 6 hereof.
2.    Indemnification. The Company shall indemnify the Director against all
Expenses actually and reasonably incurred by him in connection with any
Proceeding, except to the extent set forth in Paragraph 3 below and in
accordance with the provisions specified in this Agreement. The termination of
any such Proceeding by judgment, order of court, settlement, conviction, or upon
a plea of nolo contendre, or its equivalent, shall not, of itself, create a
presumption that the

--------------------------------------------------------------------------------

Director did not act in good faith and in a manner that he reasonably believed
to be in or not opposed to the best interests of the Company, and with respect
to any criminal proceeding, that the Director had reasonable cause to believe
that his conduct was unlawful.
3.    Exclusions. No indemnification for Expenses shall be made under this
Agreement (a) on account of any suit in which a final judgment is rendered
against the Director for an accounting of profits made from the purchase or sale
by him of securities of the Company pursuant to the provisions of Section 16(b)
of the Securities Exchange Act of 1934, as amended (the”1934 Act”), or similar
provisions of any federal, state, or local law or on account of any suit in
which a final judgment is rendered against the Director for violation of Section
10(b) or Rule 10b(5) of the 1934 Act or similar provisions of any federal,
state, or local law; (b) on account of the Director’s conduct that is finally
adjudged by a court to have constituted intentional fraud, recklessness, or
willful misconduct; (c) if a final decision by a court having jurisdiction in
the matter shall determine that such indemnification is not lawful; (d) to the
extent that the Director has voluntarily become a party to any Proceeding
without the written consent of the Company; (e) to the extent that the Director
has been reimbursed by insurance; (f) in connection with a proceeding by or in
the right of the Company in which the Director was adjudged liable to the
Company; or (g) in connection with any proceeding in which the Director was
adjudged liable to the Company on the basis of receiving an improper benefit.
4.    Indemnification of Expenses of Successful Party. Notwithstanding any other
provision of this Agreement, to the extent that the Director has been successful
on the merits or otherwise in defense of any Proceeding or in defense of any
claim, issue, or matter therein, including dismissal without prejudice, the
Director shall be indemnified against all Expenses incurred in connection
therewith (except Expenses for which the Director has been reimbursed by
insurance).

--------------------------------------------------------------------------------

12.    Savings Clause. If this Agreement or any portion of it shall be
invalidated on any ground by any court of competent jurisdiction, the Company
shall nevertheless indemnify the Director as to any Expenses with respect to any
Proceeding to the full extent permitted by any applicable portion of this
Agreement that shall not have been invalidated.
13.    Contribution. If the full indemnification provided in Paragraph 2 may not
be paid to the Director because such indemnification is prohibited by law, then
in respect of any actual or threatened Proceeding in which the Company is
jointly liable with the Director (or would be if joined in such Proceeding), the
Company shall contribute to the amount of Expenses incurred by the Director for
which indemnification is not available in such proportion as is appropriate to
reflect (a) the relative benefits received by the Company on the one hand and
the Director on the other hand from the transaction from which such proceeding
arose and (b) the relative fault of the Company and the Director, as well as any
other relevant equitable considerations. The relative fault of the Company,
which shall be deemed to include its other directors, officers and employees, on
the one hand, and of the Director, on the other hand, shall be determined by
reference to, among other things, the parties’ relative intent, knowledge,
access to information, and opportunity to correct or prevent the circumstances
resulting in such Expenses. The Company agrees that it would not be just and
equitable if contribution pursuant to this paragraph were determined by any
method of allocation that does not take account of the foregoing equitable
considerations.
14.    Notice and Information. The Director, as a condition precedent to his
right to be indemnified under this Agreement, shall give to the Company prompt
notice in writing of any claim for which indemnity will or could be sought under
this Agreement. Notice to the Company for this or any other purpose under this
Agreement shall be directed to Questar Corporation, 180 East 100 South, P. O.
Box 45433, Salt Lake City, Utah 84145-0433, Attention: Keith O. Rattie (or such
other address as the Company shall designate in writing to the Director). Any
notice to the Director shall

--------------------------------------------------------------------------------

be given at such address as he shall designate in writing to the Company. Notice
shall be deemed received three days after the date postmarked if sent by
certified or registered mail properly addressed.
In addition, the Director shall give the Company such information and
cooperation as it may reasonably require and as shall be within the Director’s
power.
15.    Effective Date. The Company’s indemnity obligations hereunder shall be
applicable to any and all claims made after the effective date of this Agreement
regardless of when the facts upon which such claims are based occurred.
16.    Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall constitute the original.
17.    Applicable Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of Utah.
18.    Continuing Effect. This Agreement shall be binding upon the Director and
upon the Company, their successors and assigns, and shall inure to the benefit
of the Director’s heirs, personal representatives, executors, assigns and estate
and to the benefit of the Company, its successors and assigns. The
indemnification under this Agreement shall continue as to the Director even
though he may have ceased to be a Director.
19.    Headings. The headings of the paragraphs of this Agreement are inserted
for convenience only and shall not be deemed to be part of this Agreement as to
affect the construction hereof.
20.    Miscellaneous. No provision of this Agreement may be modified, waived, or
discharged unless such waiver, modification or discharge is agreed to in writing
signed by the Director and the Company. No waiver by either party hereto at any
time of any breach by the other party hereto of, or compliance with, any
condition or provision of this Agreement to be performed

--------------------------------------------------------------------------------

by such other party shall be deemed a waiver of similar or dissimilar provisions
or conditions at the same or at any prior or subsequent time. No agreements or
representations, oral or otherwise, express or implied, with respect to the
subject matter hereof have been made by either party which are not set forth
expressly in this Agreement.
IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
effective as of ____________________.
