directors then still in office who either were directors at the beginning of
the period or whose election or nomination for election was previously so
approved, cease for any reason to constitute a majority thereof, or (iii) the
stockholders of the Company approve a merger or consolidation of the Company
with any other corporation, other than a merger or  1 
   consolidation
which would result in the Voting Securities of the Company outstanding
immediately prior thereto continuing to represent (either by remaining
outstanding or by being converted into Voting Securities of the surviving
entity) at least 80% of the total voting power represented by the Voting
Securities of the Company or such surviving entity outstanding immediately
after such merger or consolidation, or the stockholders of the Company approve
a plan of complete liquidation of the Company or an agreement for the sale or
disposition by the Company of (in one transaction or a series of transactions)
all or substantially all the Companys assets.  (b)           Claim: any
threatened, pending or completed action, suit or proceeding, or any inquiry or
investigation, whether instituted by the Company or any other party, that
Indemnitee in good faith, believes might lead to the institution of any such
action, suit or proceeding, whether civil, criminal, administrative,
investigative or other.  (c)           Expenses:
include attorneys fees and all other costs, expenses and obligations paid or
incurred in connection with investigating, defending, being a witness in or
participating in (including on appeal), or preparing to defend, be a witness in
or participate in any Claim relating to any Indemnifiable Event.  (d)           Indemnifiable
Event: any event or occurrence related to the fact that Indemnitee is or
was a director, officer, employee, agent or fiduciary of the Company, or is or
was serving at the request of the Company as a director, officer, employee,
trustee, agent or fiduciary of another corporation, partnership, joint venture,
employee benefit plan, trust or other enterprise, or by reason of anything done
or not done by Indemnitee in any such capacity.  (e)           Independent Legal
Counsel: an attorney or firm of attorneys, selected in accordance with the
provisions of Section 3, who shall not have otherwise performed services for
the Company or Indemnitee within the last five years (other than with respect
to matters concerning the rights of Indemnitee under this Agreement, or of
other indemnitees under similar indemnity agreements).  (f)            Potential Change
in Control: shall be deemed to have occurred if (i) the Company enters into
an agreement, the consummation of which would result in the occurrence of a
Change in Control; (ii) any person (including the Company) publicly announces
an intention to take or to consider taking actions which if consummated would
constitute a Change in Control; (iii) any person, other than a trustee or other
fiduciary holding securities under an employee benefit plan of the Company or a
corporation owned, directly or indirectly, by the stockholders of the Company
in substantially the same proportions as their ownership of stock of the
Company, who is or becomes the beneficial owner, directly or indirectly, of
securities of the Company representing 9.5% or more of the combined voting
power of the Companys then outstanding Voting Securities, increases his beneficial
ownership of such securities by five percentage points (5%) or more over the
percentage so owned by such person; or (iv) the Board adopts a resolution to
the effect that, for purposes of this Agreement, a Potential Change in Control
has occurred.  (g)           Reviewing Party:
any appropriate person or body consisting of a member or members of the
Companys Board of Directors or any other person or body appointed by the Board
who is not a party to the particular Claim for which Indemnitee is seeking
indemnification, or Independent Legal Counsel.  (h)           Voting Securities:
any securities of the Company which vote generally in the election of
directors.  2.             Basic Indemnification Arrangement.  (a)           In the event
Indemnitee was, is or becomes a party to or witness or other participant in, or
is threatened to be made a party to or witness or other participant in, a Claim
by reason of (or arising in part out of) an Indemnifiable Event, the Company
shall indemnify Indemnitee to the fullest extent permitted by law as soon as
practicable but in any event no later than thirty days after written demand is
presented to the Company, against any and all Expenses, judgments, fines,
penalties and amounts paid in settlement (including all  2 
   interest,
assessments and other charges paid or payable in connection with or in respect
of such Expenses, judgments, fines, penalties or amounts paid in settlement) of
such Claim. If so requested by Indemnitee, the Company shall advance (within
two business days of such request) any and all Expenses to Indemnitee (an  Expense Advance).  (b)           Notwithstanding the
foregoing, the obligations of the Company under Section 2(a) shall be subject
to the condition that the Reviewing Party shall not have determined (in a
written opinion, in any case in which the Independent Legal Counsel referred to
in Section 3 hereof is involved) that Indemnitee would not be permitted to be
indemnified under applicable law.  (c)           Notwithstanding the
foregoing, the obligation of the Company to make an Expense Advance pursuant to
Section 2(a) shall be subject to the condition that, if, when and to the extent
that the Reviewing Party determines that Indemnitee would not be permitted to
be so indemnified under applicable law, the Company shall be entitled to be
reimbursed by Indemnitee (who hereby agrees to reimburse the Company) for all
such amounts theretofore paid; provided, however, that if Indemnitee has
commenced or thereafter commences legal proceedings in a court, of competent
jurisdiction to secure a determination that Indemnitee should be indemnified
under applicable law, any determination made by the Reviewing Party that
Indemnitee would not be permitted to be indemnified under applicable law shall
not be binding and Indemnitee shall not be required to reimburse the Company
for any Expense Advance until a final judicial determination is made with
respect thereto (as to which all rights of appeal therefrom have been exhausted
or lapsed).  (d)           If there has not
been a Change in Control, the Reviewing Party shall be selected by the Board of
Directors, and if there has been such a Change in Control (other than a Change
in Control which has been approved by a majority of the Companys Board of
Directors who were directors immediately prior to such Change in Control), the
Reviewing Party shall be the Independent Legal Counsel referred to in Section 3
hereof.  (e)           If there has been no
determination by the Reviewing Party or if the Reviewing Party determines that
Indemnitee substantively would not be permitted to be indemnified in whole or
in part under any applicable law, Indemnitee shall have the right to commence
litigation in any court in the States of Colorado or Delaware having subject
matter jurisdiction thereof and in which venue is proper seeking an initial
determination by the court or challenging such determination by the Reviewing
Party or any aspect thereof, including the legal or factual bases therefor, and
the Company hereby consents to service of process and to appear in any such
proceeding. Any determination by the Reviewing Party otherwise shall be
conclusive and binding on the Company and Indemnitee.  (f)            Notwithstanding
anything else contained herein, in no event shall Indemnitee be entitled to
indemnification under this Agreement for any Claims that relate to liability:
(i) under Section 16(b) of the Securities Exchange Act of 1934, as amended;
(ii) under federal or state securities laws for insider trading; (iii)
conduct finally adjudged as constituting active or deliberate dishonesty or
willful fraud or illegality; (iv) conduct finally adjudged as producing an
unlawful personal benefit to Indemnitee; or (v) prior to a Change of Control,
under any Claim initiated by the Indemnitee unless the Board of Directors of
the Company shall have authorized or consented to such Claim.  3.             Change in Control.  The Company agrees that if there is a Change in Control of the
Company (other than a Change in Control which has been approved by a majority
of the Companys Board of Directors who were directors immediately prior to
such Change in Control) then with respect to all matters thereafter arising
concerning the rights of Indemnitee to indemnity payments and Expense Advances
under this Agreement or any other agreement or Company Bylaw now or hereafter
in effect relating to Claims for Indemnifiable Events, the Company shall seek
legal advice only from Independent Legal Counsel selected by Indemnitee and
approved by the Company (which approval shall not be unreasonably withheld).
Such counsel, among other things, shall render its written opinion to the
Company and Indemnitee as to whether and to what extent the Indemnitee would be
permitted to be indemnified under applicable law. The Company agrees to pay the
reasonable fees of the Independent Legal Counsel referred to above and to fully  3 
   indemnify such counsel against
any and all expenses (including attorneys fees), claims, liabilities and
damages arising out of or relating to this Agreement or its engagement pursuant
hereto.  4.             Establishment of Trust.  (a)           In the event of a
Potential Change in Control, the Company shall: (i) upon written request by
Indemnitee, create a trust for the benefit of Indemnitee, with the trustee chosen
by Indemnitee; (ii) from time to time upon written request of Indemnitee, fund
such trust in an amount sufficient to satisfy any and all Expenses reasonably
anticipated at the time of each such request to be incurred in connection with
investigating, preparing for and defending any Claim relating to an
Indemnifiable Event, and any and all judgments, fines, penalties and settlement
amounts of any and all Claims relating to an Indemnifiable Event from time to
time actually paid or claimed, reasonably anticipated or proposed to be paid.  (b)           Notwithstanding
anything else contained herein, in no event shall the Company be required to
deposit more than Five Hundred Thousand Dollars ($500,000) in any trust created
hereunder in excess of amounts deposited in respect of reasonably anticipated
Expenses.  (c)           The amount or
amounts to be deposited in the trust pursuant to the foregoing funding
obligation shall be determined by the Reviewing Party, in any case in which the
Independent Legal Counsel referred to above is involved.  (d)           The terms of the
trust shall provide that upon a Change in Control (i) the trust shall not be
revoked or the principal thereof invaded, without the written consent of the
Indemnitee, (ii) the trustee shall advance, within two business days of a
request by the Indemnitee, any and all Expenses to the Indemnitee (and the
Indemnitee hereby agrees to reimburse the trust under the circumstances under
which the Indemnitee would be required to reimburse the Company under Section
2(b) of this Agreement), (iii) the trust shall continue to be funded by the
Company in accordance with the funding obligation set forth herein, (iv) the
trustee shall promptly pay to Indemnitee all amounts for which Indemnitee shall
be entitled to indemnification pursuant to this Agreement or otherwise, and (v)
all unexpended funds in such trust shall revert to the Company upon a final
determination by the Reviewing Party or a court of competent jurisdiction, as
the case may be, that Indemnitee has been fully indemnified under the terms of
this Agreement.  5.             Indemnification for Additional Expenses.  The Company shall indemnify Indemnitee
against any and all expenses (including attorneys fees) and, if requested by
Indemnitee, shall (within two business days of such request) advance such
expenses to Indemnitee, which are incurred by Indemnitee in connection with any
action brought by Indemnitee for (i) indemnification or advance payment of
Expenses by the Company under this Agreement or any other agreement or Company
Bylaw now or hereafter in effect relating to Claims for Indemnifiable Events
and/or (ii) recovery under any directors and officers liability insurance
policies maintained by the Company, regardless of whether Indemnitee ultimately
is determined to be entitled to such indemnification, advance expense payment
or insurance recovery, as the case may be.  6.             Partial Indemnity, Etc.  If Indemnitee is entitled under any provision of this Agreement
to indemnification by the Company for some or a portion of the Expenses, judgments,
fines, penalties and amounts paid in settlement of a Claim but not, however,
for all of the total amount thereof, the Company shall nevertheless indemnify
Indemnitee for the portion thereof to which Indemnitee is entitled. Moreover,
notwithstanding any other provision of this Agreement, to the extent that
Indemnitee has been successful on the merits or otherwise in defense of any or
all Claims relating in whole or in part to an Indemnifiable Event or in defense
of any issue or matter therein, including dismissal without prejudice,
Indemnitee shall be indemnified against all Expenses incurred in connection
therewith.  7.             Burden of Proof. 
In connection with any determination by the Reviewing Party or otherwise
as to whether Indemnitee is entitled to be indemnified hereunder the burden of
proof shall be on the Company to establish that Indemnitee is not so entitled.  8.             No Presumptions. 
For purposes of this Agreement, the termination of any claim, action,
suit or proceeding, by judgment, order, settlement (whether with or without
court approval) or conviction, or upon a plea of nolo contendere, or its
equivalent, shall not create a presumption that Indemnitee did not meet  4 
   any particular standard of conduct
or have any particular belief or that a court has determined that
indemnification is not permitted by applicable law. In addition, neither the
failure of the Reviewing Party to have made a determination as to whether
Indemnitee has met any particular standard of conduct or had any particular
belief, nor an actual determination by the Reviewing Party that Indemnitee has
not met such standard of conduct or did not have such belief, prior to the
commencement of legal proceedings by Indemnitee to secure a judicial
determination that Indemnitee should be indemnified under applicable law shall
be a defense to Indemnitees claim or create a presumption that Indemnitee has
not met any particular standard of conduct or did not have any particular
belief.  9.             Nonexclusivity, Etc. The rights of the Indemnitee
hereunder shall be in addition to any other rights Indemnitee may have under
the Companys Bylaws or the Delaware General Corporation Law or otherwise. To
the extent that a change in the Delaware General Corporation Law (whether by
statute or judicial decision) permits greater indemnification by agreement than
would be afforded currently under the Companys Bylaws and this Agreement, it
is the intent of the parties hereto that Indemnitee shall enjoy by this Agreement
the greater benefits so afforded by such change.  10.           Liability Insurance. To the extent the Company
maintains an insurance policy or policies providing directors and officers
liability insurance, Indemnitee shall be covered by such policy or policies, in
accordance with its or their terms, to the maximum extent of the coverage
available for any Company director or officer.  11.           Period of Limitations. No legal action shall be
brought and no cause of action shall be asserted by or in the right of the
Company against Indemnitee, Indemnitees spouse, heirs, executors or personal
or legal representatives after the expiration of two years from the date of
accrual of such cause of action, and any claim or cause of action of the
Company shall be extinguished and deemed released unless asserted by the timely
filing of a legal action within such two-year period; provided, however, that
if any shorter period of limitations is otherwise applicable to any such cause
of action such shorter period shall govern.  12.           Amendments, Etc. No supplement, modification or
amendment of this Agreement shall be binding unless executed in writing by both
of the parties hereto. No waiver of any of the provisions of this Agreement
shall be deemed or shall constitute a waiver of any other provisions hereof
(whether or not similar) nor shall such waiver constitute a continuing waiver.  13.           Subrogation. In the event of payment under this
Agreement, the Company shall be subrogated to the extent of such payment to all
of the rights of recovery of Indemnitee, who shall execute all papers required
and shall do everything that may be necessary to secure such rights, including
the execution of such documents necessary to enable the Company effectively to
bring suit to enforce such rights.  14.           No Duplication of Payments. The Company shall not
be liable under this Agreement to make any payment in connection with any Claim
made against Indemnitee to the extent Indemnitee has otherwise actually
received payment (under any insurance policy, Bylaw or otherwise) of the
amounts otherwise indemnifiable hereunder.  15.           Binding Effect, Etc. This Agreement shall be
binding upon and inure to the benefit of and be enforceable by the parties
hereto and their respective successors, assigns, including any direct or
indirect successor by purchase, merger, consolidation or otherwise to all or
substantially all of the business, and/or assets of the Company, spouses,
heirs, executors and personal and legal representatives. This Agreement shall
continue in effect regardless of whether Indemnitee continues to serve as an
officer or director of the Company or of any other enterprise at the Companys
request.  16.           Severability. The provisions of this Agreement
shall be severable in the event that any of the provisions hereof (including
any provision within a single section, paragraph or sentence) is held by a
court of competent jurisdiction to be invalid, void or otherwise unenforceable
in any respect, and the validity and enforceability of any such provision in every
other respect and of the remaining provisions hereof shall not be in any way
impaired and shall remain enforceable to the fullest extent permitted by law.  5 
   17.           Governing Law. This Agreement shall be governed by
and construed and enforced in accordance with the laws of the State of Delaware
applicable to contracts made and to be performed in such state without giving
effect to the principles of conflicts of laws.  IN WITNESS WHEREOF,
the parties hereto have executed this Agreement as of June 14, 2001  WESTERN GAS
