                                  ARTICLE III

                                 PURCHASE PRICE

      3.1   PURCHASE PRICE AND CONSIDERATION. The purchase price for the Assets
shall be $61,706,000 ("Purchase Price"). At Closing, Buyer shall pay Sellers the
Purchase Price, as adjusted pursuant to this Article III, less the Deposit,. The
total consideration from Buyer to Sellers shall include the Purchase Price, as
adjusted pursuant to this Article III, plus the assumption of the Assumed
Liabilities.

$75,000 to reimburse Buyer for a portion of costs incurred in the course of due
diligence resulting from Buyer entering into this Agreement. This reimbursement,
if any, shall be made at the Closing or, if no Closing occurs, on or before
December 23, 2002.

      3.4   ALLOCATION OF THE PURCHASE PRICE. With respect to the E&P
Properties, the Purchase Price shall be allocated to the Assets as set forth in
Schedule 2.2(b) (the "Allocated Values"), which allocation shall be binding on
Sellers and Buyer and shall be used for the purposes of adjusting the Purchase
Price pursuant to Sections 3.6, 3.7, 3.9 and 12.4 and is not intended as a means
of valuation for any other purpose.

      3.5   ADJUSTMENT TO PURCHASE PRICE. The Purchase Price shall be adjusted
at Closing pursuant to the "Settlement Statement" prepared by Sellers and
submitted to Buyer at least nine days prior to Closing for Buyer's comment and
review. The Settlement Statement shall set forth

                                   -8-
<PAGE>

the Adjusted Purchase Price and associated calculations used to determine such
adjustments. The "Adjusted Purchase Price" shall be calculated as follows:

      Adjusted Purchase Price = $61,706,000 plus (Increased Debt + Credit
      Interest + Oil in Tanks + Positive GAAP Adjustments (if the net amount of
      all GAAP Adjustments is positive)) minus (Decreased Debt + Third Party
      Fees + Title Adjustments + Environmental Adjustments + GAAP Adjustments
      (if the net amount of all GAAP Adjustments is negative) and Gas
      Imbalances).

Where:

"Increased Debt" means the principal balance of the Company Debt immediately
prior to the Closing minus the principal balance of the Company Debt as of the
Effective Time (as shown on the Balance Sheet) but only to the extent that the
proceeds from any increase in Company Debt during such period does not result in
a breach of the representations of Sellers in Section 4.10 or the covenants of
Sellers in Section 6.1. If this calculation results in a negative number, the
value of "Increased Debt" shall be deemed to be zero.

"Credit Interest" means any accrued but unpaid interest and Commitment Fees (as
defined in the Company Debt) relating to the Company Debt at the time
immediately prior to Closing.

"Oil in Tanks" means the value of all oil retained by Sellers in pipelines,
tanks or other storage as of the Effective Time, which has been calculated by
Sellers as $137,109, and is subject to review by the parties.

"GAAP Adjustments" means any the aggregate net dollar amount of adjusting
journal entries that would be necessary in order to fairly present in accordance
with GAAP, applied on a basis consistent with the audited financial statements
of the Seller for the years ended December 31, 2001 and 2000, the Balance Sheet
but excluding any adjustment made in relation to (a) federal or state taxes, (b)
account coding, (c) depreciation depletion and amortization (DD&A), or (d) any
adjustment that duplicates any other adjustment to the Purchase Price. It is
agreed that (i) any amount shown on the Balance Sheet as an account receivable
that has not been paid as of the Closing Date shall be deemed to be required
under GAAP to be subtracted from the assets on the Balance Sheet, (ii) any
liability of Sellers as of June 30, 2002 that is not recorded on the Balance
Sheet shall be deemed to be required under GAAP to be added to the liabilities
on the Balance Sheet, and (iii) the liabilities of Sellers required by GAAP to
be shown on the Balance Sheets as of June 30, 2002 shall include Seller's good
faith estimate of all Taxes, whether or not assessed as of June 30, 2002, that
are based upon or measured by ownership of the Assets as of June 30, 2002 or
production of Hydrocarbons through June 30, 2002. All adjustments, whether
positive or negative, shall be calculated, and the net amount of adjustments
determined. No positive or negative GAAP Adjustment shall be made unless the
absolute value of the net amount of all such adjustments is equal to or greater
than $150,000.

"Decreased Debt" means the principal balance of the Company Debt as of the
Effective Time (as shown on the Balance Sheet) minus the principal balance of
Company Debt immediately prior to Closing. If this calculation results in a
negative number, then the value of "Decreased Debt" shall be deemed to be zero.

                                   -9-
<PAGE>

"Third Party Fees" means fees incurred after the Effective Time paid to Petrie
Parkman & Co. and Davis Graham & Stubbs LLP for services related to the
transactions contemplated by this Agreement as well as such fees for other third
parties, minus $80,000.

"Title Adjustments" means any Title Defect Adjustment made pursuant to Section
3.5 of this Agreement.

"Environmental Adjustment" means any adjustment to Purchase Price for an
Environmental Breach made pursuant to Section 3.6 of this Agreement.

"Gas Imbalances" means the gas imbalances shown on Schedule 4.13 calculated at
the rate of $2.00 per mcf.

      3.6   PURCHASE PRICE ADJUSTMENTS FOR TITLE DEFECTS.

            (a)   Review of Title Records. Upon execution of this Agreement,
Sellers shall make available to Buyer during regular business hours all Records
in Sellers' possession relating to the title to the Properties. Buyer shall be
entitled to review said title Records. Buyer shall have the right to reasonably
request copies of any and all such title Records and, upon such request, Sellers
shall provide the requested copies to Buyer.

            (b)   Notice Of Title Defects. Buyer shall have the right to provide
Sellers with written notice of Title Defects at any time from the date of this
Agreement to ten (10) days before the Closing Date. Such notice shall be in
writing and shall be effective only if it includes all of the following: (i) a
description of the E&P Property affected by the Title Defect, (ii) the
reasonable basis for the Title Defect, (iii) reasonable documentation supporting
the basis for the Title Defect, (iv) the Allocated Value of the affected E&P
Property, and (v) the dollar value associated with the Title Defect (the "Title
Defect Value") and the computations upon which Buyer's belief is based.
"Reasonable documentation supporting the basis" shall mean, for Title Defects
having the following bases: (a) if the basis is derived from a document, a copy
of such document, or pertinent part thereof, (b) if the basis is a gap in
Sellers' chain of title, the document preceding and following the gap, or a
title opinion reciting the gap in reasonable detail, (c) if the basis is a lien
or encumbrance, the document creating the lien or encumbrance or a title opinion
or title report reciting the lien or encumbrance in reasonable detail including
recording references, or (d) if the basis is failure to pay a rental when due on
a federal lease, a serial register page or other documentation from the United
States Bureau of Land Management (BLM) or the United States Minerals Management
Service (MMS).

            (c)   Title Defect Adjustments And Exclusions. The Purchase Price
shall be reduced by an amount equal to the Title Defect Value (which reduction
shall be called a "Title Defect Adjustment") if the Title Defect Value for any
particular Asset exceeds $25,000 (as a threshold, but not as a deductible),
provided that the aggregate of all Title Defect Values exceed $100,000. No Title
Defect Adjustment shall be made if (i) Buyer agrees in writing to waive the
relevant Title Defect, (ii) the basis for the Title Defect has been removed by
Sellers at its sole cost and expense, or (iii) Sellers and Buyer reach an
agreement regarding cure of the Title Defect. If an Asset that is the subject of
the value of Title Defects has not been given an

                                  -10-
<PAGE>

Allocated Value, or if the Asset's Allocated Value is zero, Sellers are deemed
to have Defensible Title to such Asset.

            (d)   Title Defect Value. The Title Defect Value for any Asset shall
not exceed the Allocated Value of the Asset and shall be determined as follows:
(i) If the effect of the Title Defect is to reduce the actual Net Revenue
Interest to an amount less than that stated in Schedule 2.2(b), and if the Asset
is not subject to a reversion after payout, then the Title Defect Value is the
product of the Allocated Value attributed to such Asset, multiplied by a
fraction, the numerator of which is the difference between the Net Revenue
Interest set forth in Exhibit A and the actual Net Revenue Interest, and the
denominator of which is the Net Revenue Interest stated in Exhibit A; or (ii) or
if the Title Defect represents an obligation, encumbrance, burden or charge upon
the affected Asset (including any increase in Working Interest for which there
is not a proportionate increase in the Net Revenue Interest), the amount of the
Title Defect Value is to be determined by Buyer after taking into account: (A)
Allocated Value of the Asset, (B) the portion of the Asset affected by the Title
Defect, (C) the legal effect of the Title Defect, (D) the potential economic
effect of the Title Defect over the life of the affected Asset, (E) if the Title
Defect is a lien or encumbrance on the affected portion of the Asset, the cost
of removing such lien or encumbrance, and (F) the Title Defect Values placed
upon the Title Defect by Buyer and Sellers.

            (e)   Interest Additions. No later than ten Business Days prior to
Closing, Buyer will notify Sellers of any interest that should be an Asset or
Assumed Liability hereunder, but that is not listed, including any interest that
entitles Sellers to receive more than the NRI or obligates Sellers to bear costs
and expenses in an amount less than the WI, as WI and NRI are set forth on
Schedule 2.2(b), and including overriding royalty interests in wells drilled and
completed prior to the Effective Time (collectively, "Interest Additions");
provided, however, that the following shall not be considered Interest
Additions: (a) an increased NRI resulting from a reduced royalty rate due to
stripper well classification and (b) an after payout increase in WI or NRI
pursuant to a farmin, farmout or other agreement. Buyer's notice under this
Section 3.6(e) shall be in writing and shall include (i) a description of the
Interest Addition, (ii) the basis for the Interest Addition, (iii) the Allocated
Value of the Asset affected by the Interest Addition, and (iv) the value of the
Interest Addition or the amount by which Buyer, as applicable, believes the
Allocated Value of the Asset has been increased by the Interest Addition ("Value
of Interest Addition") and the computations upon which Buyer's belief is based,
which shall be consistent with the manner in which Title Defect Values are
determined. The Purchase Price shall be adjusted upwards for Interest Additions
only if (1) an Interest Addition exceeds $25,000, and (2) the sum of all
Interest Additions exceed $100,000, in which case the value of such Interest
Additions shall be offset against any downward adjustments for Title Defects,
and the amount of offset shall not exceed the total amount of Title Defect
Adjustment.

      3.7   PURCHASE PRICE ADJUSTMENT FOR ENVIRONMENTAL DEFECTS.

            (a)   Inspection of Premises. Upon execution of this Agreement and
subject to the Indemnification Agreement, Buyer shall be provided access during
regular business hours to the Seller-operated E&P Properties, and Sellers shall
use reasonable efforts to obtain permission for Buyer to gain access to the
third party-operated E&P Properties, for the purpose of inspecting the
environmental and physical condition of the same.

                                  -11-
<PAGE>

            (b)   Notice. At any time from the date of this Agreement to ten
days before the Closing Date, Buyer shall have the right to provide Sellers with
written notice (an "Environmental Notice") of any fact or circumstance that
evidences the material breach of Sellers' representation in Section 4.5
("Environmental Breach"). The Environmental Notice shall be in writing and shall
include all of the following: (i) a description of the Asset Property affected
by the Environmental Breach, (ii) the reasonable basis for the Environmental
Breach, (iii) reasonable documentation supporting the basis for the
Environmental Breach, (iv) the Allocated Value of the affected Asset, and (v)
Buyer's good faith estimate of the dollar amount of loss that will be incurred
by Buyer as a result of the Environmental Breach (the "Environmental Breach
Value") and the computations upon which Buyer's belief is based.

            (c)   Adjustment for Environmental Breach. If Buyer delivers an
Environmental Notice to Sellers, Sellers, at their election, shall have the
option of (A) remediating the Environmental Breach to the satisfaction of (i)
the appropriate state and federal agencies having jurisdiction prior to Closing,
or (ii) a third party where that third party has brought a claim for damages
resulting from the same set of facts giving rise to the Environmental Breach, or
(B) subject to Section 3.9, paying the Environmental Breach Value associated
with the Environmental Breach, and thereafter, in either case, Buyer shall waive
and indemnify Sellers for all losses associated with such Environmental Breach.
The Purchase Price shall be reduced by the Environmental Breach Value (each such
adjustment, an "Environmental Breach Adjustment") if the loss with respect to
any particular E&P Property exceeds $25,000 (as a threshold and not as a
deductible), and further provided that the aggregate of all Environmental Breach
Adjustments exceed $100,000.

      3.8   PURCHASE PRICE ADJUSTMENT DISPUTES. Notwithstanding Section 13.11(a)
and (b), if the parties disagree with the dollar amount of or information used
to calculate any adjustment to the Purchase Price pursuant to Section 3.5 or 3.6
or 3.7, then such party shall, at least seven (7) days prior to the Closing
Date, deliver a notice by facsimile or hand delivery to the other party stating
the existence and nature of such disagreement. Any such notice shall specify
those items or amounts subject to dispute. If such notice of disagreement is
delivered, then the Chief Operating Officer of Buyer and the President of
Sellers meet regularly as necessary for six (6) days following receipt of such
notice and use reasonable efforts to reach an agreement on the disputed items or
amounts. If within six (6) days following receipt of such notice the parties
have not reached an agreement, the parties shall submit the matter to Expedited
Arbitration for a final determination of the disputed matter.

      3.9   PREFERENTIAL RIGHTS. The parties acknowledge that certain of the E&P
Properties may be subject to a preferential right to purchase, as set forth on
Schedule 3.9. To the extent any preferential right is validly exercised,
resulting in the transfer of a Lease or Well to a third party, the Purchase
Price shall be reduced, or that portion of the Purchase Price previously paid to
Sellers by Buyer shall be refunded, in an amount equal to the Allocated Value
for the portion of the Assets subject to the validly exercised preferential
right. This reduction or refund, as the case may be, shall be Buyer's sole
remedy for the exercise of any preferential right affecting the E&P Properties.
If Sellers have transferred title or an interest in such a property to Buyer,
Buyer shall take such steps as necessary to convey the property to the holder of
the preferential right.

                                  -12-
<PAGE>

      3.10  CASUALTY LOSS. Prior to Closing, if a portion of the Assets is
destroyed by fire or other casualty, is taken or threatened to be taken in
condemnation or under the right of eminent domain ("Casualty Loss"), Buyer shall
purchase the Asset at Closing for, at Buyer's option, (i) the Allocated Value of
the Asset reduced by the estimated cost to repair such Asset (with equipment of
similar utility) up to the Allocated Value thereof (the reduction being the "Net
Casualty Loss") or (ii) the Allocated Value of the Asset and Sellers shall
assign Buyer all of Sellers' rights to any awards or other payments from third
parties arising out of the Casualty Loss.

      3.11  CONSENTS. If a necessary consent to assign any Lease or other Asset
has not been obtained as of the Closing, then the portion of the Assets for
which such consent has not been obtained shall not be excluded from the Assets
at the Closing, and Sellers shall use their reasonable efforts to, but shall not
be required to, obtain such consent as promptly as possible following Closing.
Buyer shall reasonably cooperate with Sellers in obtaining any required consent
including providing assurances of reasonable financial conditions, but Buyer
shall not be required to expend funds or make any other type of financial
commitments a condition of obtaining such consent.

injunctive relief to preserve the status quo pending arbitration.

            (a)   Any party may submit any dispute to arbitration by giving
written notice to the other parties to such dispute. Within ten Business Days
after receipt of such notice, each party to the dispute shall appoint one
arbitrator and within ten Business Days thereafter the two arbitrators so
appointed shall select a third arbitrator. If either party shall fail to make
such appointment within such ten-day period, the other party may request the
American Arbitration Association to appoint the second arbitrator. The American
Arbitration Association may thereupon appoint the second arbitrator. If the two
appointed arbitrators shall fail to select the third arbitrator within such
ten-day period, the parties to the dispute shall mutually select the third
arbitrator. If such parties are unable to agree upon such selection, then any
party may, upon at least five Business Days' prior written notice to the other
party, request the American Arbitration Association to appoint the third
arbitrator. The American Arbitration Association may thereupon appoint the third
arbitrator ("Third Arbitrator"). The Third Arbitrator shall be experienced in
corporate and financial matters and shall be impartial and unrelated, directly
or indirectly, so far as employment of services is concerned to either of the
parties or any of their respective affiliates; provided that, to the extent
concern matters of (i) oil and gas law, geology, and/or petroleum engineering
and/or (ii) environmental law and/or environmental science, then the Third
Arbitrator must be trained and knowledgeable in such matters.

            (b)   The Third Arbitrator shall investigate the facts and shall
hold hearings at which the parties may conduct limited discovery, present
evidence and arguments, be represented by counsel and conduct cross examination.
The Third Arbitrator shall render a written decision on the matter presented to
him or her as soon as practicable after his or her appointment and in any event
not more than forty-five days after such appointment. The decision of the Third
Arbitrator, which may include equitable relief, shall be final and binding on
the parties hereto, and judgment upon the decision may be entered in any court
having jurisdiction thereof. If the Third Arbitrator shall fail to render a
decision within such forty-five day period, either party may institute such
action or proceeding in such court as shall be appropriate in the circumstances
and upon the institution of such action, the arbitration proceeding shall be
terminated and shall be of no further force and effect. The prevailing party (in
the arbitration or in the court proceeding, as applicable) shall be awarded
reasonable attorneys' fees, expert and nonexpert witness costs and expenses, and
other costs and expenses incurred in connection with the arbitration, and the
fees and costs of the Third Arbitrator shall be borne by the nonprevailing party
unless, in either case, the Third Arbitrator or the court, as the case may be
for good cause determine otherwise. In resolving any dispute, the Third
Arbitrator shall apply the provisions of this Agreement, without varying
therefrom in any respect. The Third Arbitrator shall not have the power to add
to, modify or change any of the provisions of this Agreement.

      office of the American Arbitration Association ("AAA").

                  (2)   The parties shall attempt to select a mutually
      acceptable arbitrator. If the parties are unable to agree concerning the
      selection of an arbitrator within three (3) days of the respondent's
      receipt of the demand for arbitration, any party may notify AAA that the
      parties are unable to agree, and shall simultaneously provide a copy of
      its notice to all other parties. Within five (5) Business Days of AAA's
      receipt of notice from the parties that they are unable to agree to an
      arbitrator, AAA shall select an arbitrator.

                  (3)   Within three (3) days of receipt of written notice
      confirming the selection of the arbitrator, each party may submit to the
      arbitrator a written brief in support of its position no longer than five
      (5) pages, single spaced, on 8 1/2 by 11, with no more than twenty (20)
      pages of exhibits.

                  (4)   The arbitrator shall follow applicable law and
      precedent.

                  (5)   If the written briefs of both parties present one or
      more questions of law and no genuine issue as to any material fact, the
      arbitrator shall decide the dispute based solely upon the written
      submissions of the parties. If the arbitrator determines that there is a
      genuine concerning one or more material facts, the arbitrator may: (a)
      make a single request that the parties submit additional information or
      briefing within five (5) days of the arbitrator's request and/or (b)
      schedule a hearing to be held no later than five (5) Business Days after
      (i) the notice scheduling the hearing, if no additional information or
      briefing is requested, or (ii) the last date permitted for the submission
      of additional information or briefs, if applicable. Any hearing shall be
      limited to two (2) days, unless otherwise agreed by the parties.

                  (6)   The arbitrator shall render a decision within five (5)
      Business Days after the latest of: (a) the arbitrator's receipt of the
      written submissions of the parties; (b) the arbitrator's receipt of
      additional information or briefing requested by the arbitrator, if
      applicable; or (c) the conclusion of a hearing, if applicable. The
      arbitrator need not provide a written rationale for his or her decision.

                  (7)   There shall be no appeal from the decision of the
      arbitrator, and the decision shall be enforceable in any court with
      jurisdiction.

            (d)   Each party shall bear its own attorneys' fees and costs and
      shall bear one-half of the AAA and arbitrator's fees and costs with
      respect to any Arbitration.

      13.12 PUBLIC STATEMENTS. All public statements concerning this Agreement
and the transactions contemplated pursuant to this agreement shall be made only
upon the mutual consent of Buyer and Sellers, which consent shall not be
unreasonably withheld.

                            INDEMNIFICATION AGREEMENT

     INDEMNIFICATION AGREEMENT, made and executed as of the 15th day of April,
2004 (this "Agreement"), by and between Bill Barrett Corporation, a Delaware
corporation (the "Company"), and _______________, an individual resident of the
State of Colorado (the "Indemnitee").

     WHEREAS, the Company is aware that, in order to induce highly competent
persons to serve the Company as directors or officers or in other capacities,
the Company must provide such persons with adequate protection through insurance
and indemnification against inordinate risks of claims and actions against them
arising out of their service to and activities on behalf of the Company;

     WHEREAS, the Company recognizes that the increasing difficulty in obtaining
directors' and officers' liability insurance, the increasing cost of such
insurance and the general reductions in coverage of such insurance have made
attracting and retaining such persons more difficult;

     WHEREAS, the Company recognizes the substantial increase in corporate
litigation in general, subjecting directors and officers to expensive litigation
risks at the same time as the availability and coverage of liability insurance
has been severely limited;

     WHEREAS, the Board of Directors of the Company has determined that it is in
the best interests of the Company's stockholders that the Company act to assure
such persons that there will be increased certainty of such protection in the
future;

     WHEREAS, it is reasonable, prudent and necessary for the Company to
contractually obligate itself to indemnify such persons to the fullest extent
permitted by applicable law so that they will continue to serve the Company free
from undue concern that they will not be so indemnified; and

     WHEREAS, the Indemnitee is willing to serve, continue to serve and take on
additional service for or on behalf of the Company or any of its direct or
indirect wholly-owned subsidiaries on the condition that he/she be so
indemnified.

     NOW, THEREFORE, in consideration of the premises and the mutual promises
and covenants contained herein, and for other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, the Company and
the Indemnitee do hereby agree as follows:

     1. DEFINITIONS. For purposes of this Agreement:

        (a) "Change in Control" shall mean:

<PAGE>

            (i)   a "change in control" of the Company of a nature that would be
                  required to be reported in response to Item 6(e) of Schedule
                  14A for a proxy statement filed under Section 14(a) of the
                  Securities Exchange Act of 1934, as amended (the "Act"), as in
                  effect on the date of this Agreement;

            (ii)  a "person" (as that term is used in 14(d)(2) of the Act)
                  becomes the beneficial owner (as defined in Rule 13d-3 under
                  the Act) directly or indirectly of securities representing 30%
                  or more of the combined voting power for election of directors
                  of the then outstanding securities of the Company unless (1)
                  such person is a signatory to the Stockholders' Agreement for
                  the Company and (2) such person becomes such a beneficial
                  owner of such securities as a result of a transaction with
                  one, or more than one, other person who is also a signatory to
                  such Stockholders' Agreement;

            (iii) the individuals who at the beginning of any period of two
                  consecutive years or less (starting on or after the date of
                  this Agreement) constitute the Company's Board of Directors
                  cease for any reason during such period to constitute at least
                  a majority of the Company's Board of Directors, unless the
                  election or nomination for election of each new member of the
                  Board of Directors was approved in advance by vote of a
                  majority of the members of such Board of Directors then still
                  in office who were members of such Board of Directors at the
                  beginning of such period;

            (iv)  the stockholders of the Company approve any reorganization,
                  merger, consolidation or share exchange as a result of which
                  the common stock of the Company shall be changed, converted or
                  exchanged into or for securities of another organization or
                  any dissolution or liquidation of the Company or any sale or
                  the disposition of 50% or more of the assets or business of
                  the Company; or

            (v)   the stockholders of the Company approve any reorganization,
                  merger, consolidation or share exchange with another
                  corporation unless (1) the persons who were the beneficial
                  owners of the outstanding shares of the common stock of the
                  Company immediately before the consummation of such
                  transaction beneficially own more than 60% of the outstanding
                  shares of the common stock of the successor or survivor
                  corporation in such transaction immediately following the
                  consummation of such transaction and (2) the number of shares
                  of the common stock of such successor or survivor corporation
                  beneficially owned by the persons described in Section
                  1(a)(v)(1) immediately following the

                                       2
<PAGE>

                  consummation of such transaction is beneficially owned by each
                  such person in substantially the same proportion that each
                  such person had beneficially owned shares of the Company
                  common stock immediately before the consummation of such
                  transaction, provided (3) the percentage described in Section
                  1(a)(v)(1) of the beneficially owned shares of the successor
                  or survivor corporation and the number described in Section
                  1(a)(v)(2) of the beneficially owned shares of the successor
                  or survivor corporation shall be determined exclusively by
                  reference to the shares of the successor or survivor
                  corporation which result from the beneficial ownership of
                  shares of common stock of the Company by the persons described
                  in Section 1(a)(v)(1) immediately before the consummation of
                  such transaction.

        (b) "Disinterested Director" shall mean a director of the Company who is
     not or was not a party to the action, suit, investigation or proceeding in
     respect of which indemnification is being sought by the Indemnitee.

        (c) "Expenses" shall include all attorneys' fees, retainers, court
     costs, transcript costs, fees of experts, witness fees, travel expenses,
     duplicating costs, printing and binding costs, telephone charges, postage,
     delivery service fees, and all other disbursements or expenses incurred in
     connection with prosecuting, defending, preparing to prosecute or defend,
     investigating or being or preparing to be a witness in any threatened,
     pending or completed action, suit or proceeding, whether civil, criminal,
     administrative or investigative in nature.

        (d) "Independent Counsel" shall mean a law firm or a member of a law
     firm that neither is presently nor in the past five years has been retained
     to represent (i) the Company or the Indemnitee in any matter material to
     either such party or (ii) any other party to the action, suit,
     investigation or proceeding giving rise to a claim for indemnification
     hereunder. Notwithstanding the foregoing, the term "Independent Counsel"
     shall not include any person who, under the applicable standards of
     professional conduct then prevailing, would have a conflict of interest in
     representing either the Company or the Indemnitee in an action to determine
     the Indemnitee's right to indemnification under this Agreement.

        (e) "Stockholders' Agreement" shall mean the agreement, dated March 28,
     2002, by and among the Company and the investors named therein, as may be
     amended from time to time.

     2. SERVICE BY THE INDEMNITEE. The Indemnitee agrees to serve as a director
or officer of the Company and will discharge his/her duties and responsibilities
to the best of his/her ability so long as the Indemnitee is duly elected or
qualified in accordance with the provisions of the Certificate of Incorporation,
as amended (the "Certificate"), and the Bylaws, as amended (the "Bylaws"), of
the Company and the General Corporation Law of the State of Delaware, as amended
(the "DGCL"), or until his/her earlier death, retirement, resignation or
removal. The

                                       3
<PAGE>

Indemnitee may at any time and for any reason resign from such position (subject
to any other obligation, whether contractual or imposed by operation of law), in
which event this Agreement shall continue in full force and effect after such
resignation. Nothing in this Agreement shall confer upon the Indemnitee the
right to continue in the employ of the Company or as a director of the Company,
or affect the right of the Company to terminate, in the Company's sole
discretion (with or without cause) and at any time, the Indemnitee's employment,
in each case, subject to any contractual rights of the Indemnitee created or
existing otherwise than under this Agreement.

     3. INDEMNIFICATION. The Company shall indemnify the Indemnitee and advance
Expenses to the Indemnitee as provided in this Agreement to the fullest extent
permitted by the Certificate, the Bylaws in effect as of the date hereof and the
DGCL or other applicable law in effect on the date hereof and to any greater
extent that the DGCL or applicable law may in the future from time to time
permit. Without diminishing the scope of the indemnification provided by this
Section 3, the rights of indemnification of the Indemnitee provided hereunder
shall include, but shall not be limited to, those rights hereinafter set forth,
except that no indemnification shall be paid to the Indemnitee:

        (a) on account of any action, suit or proceeding in which judgment is
     rendered against the Indemnitee for disgorgement of profits made from the
     purchase or sale by the Indemnitee of securities of the Company pursuant to
     the provisions of Section 16(b) of the Act or similar provisions of any
     federal, state or local statutory law;

        (b) on account of conduct of the Indemnitee which is finally adjudged by
     a court of competent jurisdiction to have been knowingly fraudulent or to
     constitute willful misconduct;

        (c) in any circumstance where such indemnification is expressly
     prohibited by applicable law;

        (d) with respect to liability for which payment is actually made to the
     Indemnitee under a valid and collectible insurance policy or under a valid
     and enforceable indemnity clause, Bylaw or agreement (other than this
     Agreement), except in respect of any liability in excess of payment under
     such insurance, clause, Bylaw or agreement;

        (e) if a final decision by a court having jurisdiction in the matter
     shall determine that such indemnification is not lawful (and, in this
     respect, both the Company and the Indemnitee have been advised that it is
     the position of the Securities and Exchange Commission that indemnification
     for liabilities arising under the federal securities laws is against public
     policy and is, therefore, unenforceable, and that claims for
     indemnification should be submitted to the appropriate court for
     adjudication); or

        (f) in connection with any action, suit or proceeding by the Indemnitee
     against the Company or any of its direct or indirect wholly-owned

                                       4
<PAGE>

     subsidiaries or the directors, officers, employees or other Indemnitees of
     the Company or any of its direct or indirect wholly-owned subsidiaries, (i)
     unless such indemnification is expressly required to be made by law, (ii)
     unless the action, suit or proceeding was previously authorized by a
     majority of the Board of Directors of the Company, (iii) unless such
     indemnification is provided by the Company, in its sole discretion,
     pursuant to the powers vested in the Company under applicable law or (iv)
     except as provided in Sections 12 and 14 hereof.

     4. ACTIONS OR PROCEEDINGS OTHER THAN AN ACTION BY OR IN THE RIGHT OF THE
COMPANY. The Indemnitee shall be entitled to the indemnification rights provided
in this Section 4 if the Indemnitee was or is a party or is threatened to be a
party to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative in nature, other than
an action by or in the right of the Company, by reason of the fact that the
Indemnitee is or was a director, officer, employee, agent or fiduciary of the
Company, or any of its direct or indirect wholly-owned subsidiaries, or is or
was serving at the request of the Company, or any of its direct or indirect
wholly-owned subsidiaries, as a director, officer, employee, agent or fiduciary
of any other entity, including, but not limited to, another corporation,
partnership, limited liability company, employee benefit plan, joint venture,
trust or other enterprise, or by reason of any act or omission by him/her in
such capacity. Pursuant to this Section 4, the Indemnitee shall be indemnified
against all Expenses, judgments, penalties (including excise and similar taxes),
fines and amounts paid in settlement which were actually and reasonably incurred
by the Indemnitee in connection with such action, suit or proceeding (including,
but not limited to, the investigation, defense or appeal thereof), if the
Indemnitee acted in good faith and in a manner the Indemnitee reasonably
believed to be in or not opposed to the best interests of the Company, and, with
respect to any criminal action or proceeding, had no reasonable cause to believe
his/her conduct was unlawful.

     5. ACTIONS BY OR IN THE RIGHT OF THE COMPANY. The Indemnitee shall be
entitled to the indemnification rights provided in this Section 5 if the
Indemnitee was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding brought by or in the
right of the Company to procure a judgment in its favor by reason of the fact
that the Indemnitee is or was a director, officer, employee, agent or fiduciary
of the Company, or any of its direct or indirect wholly-owned subsidiaries, or
is or was serving at the request of the Company, or any of its direct or
indirect wholly-owned subsidiaries, as a director, officer, employee, agent or
fiduciary of another entity, including, but not limited to, another corporation,
partnership, limited liability company, employee benefit plan, joint venture,
trust or other enterprise, or by reason of any act or omission by him/her in any
such capacity. Pursuant to this Section 5, the Indemnitee shall be indemnified
against all Expenses actually and reasonably incurred by him/her in connection
with the defense or settlement of such action, suit or proceeding (including,
but not limited to the investigation, defense or appeal thereof), if the
Indemnitee acted in good faith and in a manner the Indemnitee reasonably
believed to be in or not opposed to the best interests of the Company; provided,
however, that no such indemnification shall be made in respect of any claim,
issue or matter as to which the Indemnitee shall have been adjudged to be liable
to the Company, unless and only to the extent that the Court of Chancery of the
State of Delaware or the court in which such action, suit or proceeding was
brought shall determine upon application that, despite the adjudication of
liability but in

                                       5
<PAGE>

view of all the circumstances of the case, the Indemnitee is fairly and
reasonably entitled to indemnity for such Expenses which such court shall deem
proper.

     6. GOOD FAITH DEFINITION. For purposes of this Agreement, the Indemnitee
shall be deemed to have acted in good faith and in a manner the Indemnitee
reasonably believed to be in or not opposed to the best interests of the
Company, or, with respect to any criminal action or proceeding, to have had no
reasonable cause to believe the Indemnitee's conduct was unlawful, if such
action was based on any of the following: (a) the records or books of the
account of the Company or other enterprise, including financial statements; (b)
information supplied to the Indemnitee by the officers of the Company or other
enterprise in the course of his/her duties; (c) the advice of legal counsel for
the Company or other enterprise; or (d) information or records given in reports
made to the Company or other enterprise by an independent certified public
accountant or by an appraiser or other expert selected with reasonable care by
the Company or other enterprise.

     7. INDEMNIFICATION FOR EXPENSES OF SUCCESSFUL PARTY. Notwithstanding the
other provisions of this Agreement, to the extent that the Indemnitee has served
on behalf of the Company, or any of its direct or indirect wholly-owned
subsidiaries, as a witness or other participant in any class action or
proceeding, or has been successful, on the merits or otherwise, in defense of
any action, suit or proceeding referred to in Sections 4 and 5 hereof, or in
defense of any claim, issue or matter therein, including, but not limited to,
the dismissal of any action without prejudice, the Indemnitee shall be
indemnified against all Expenses actually and reasonably incurred by the
Indemnitee in connection therewith.

     8. PARTIAL INDEMNIFICATION. If the Indemnitee is entitled under any
provision of this Agreement to indemnification by the Company for some or a
portion of the Expenses, judgments, fines and amounts paid in settlement
actually and reasonably incurred by the Indemnitee in connection with the
investigation, defense, appeal or settlement of such suit, action, investigation
or proceeding described in Sections 4 and 5 hereof, but is not entitled to
indemnification for the total amount thereof, the Company shall nevertheless
indemnify the Indemnitee for the portion of such Expenses, judgments, penalties,
fines and amounts paid in settlement actually and reasonably incurred by the
Indemnitee to which the Indemnitee is entitled.

     9. PROCEDURE FOR DETERMINATION OF ENTITLEMENT TO INDEMNIFICATION. (a) To
obtain indemnification under this Agreement, the Indemnitee shall submit to the
Company a written request, including documentation and information which is
reasonably available to the Indemnitee and is reasonably necessary to determine
whether and to what extent the Indemnitee is entitled to indemnification. The
Secretary of the Company shall, promptly upon receipt of a request for
indemnification, advise the Board of Directors in writing that the Indemnitee
has requested indemnification. Any Expenses incurred by the Indemnitee in
connection with the Indemnitee's request for indemnification hereunder shall be
borne by the Company. The Company hereby indemnifies and agrees to hold the
Indemnitee harmless for any Expenses incurred by the Indemnitee under the
immediately preceding sentence irrespective of the outcome of the determination
of the Indemnitee's entitlement to indemnification.

                                       6
<PAGE>

     (b) Upon written request by the Indemnitee for indemnification pursuant to
Sections 4 and 5 hereof, the entitlement of the Indemnitee to indemnification
pursuant to the terms of this Agreement shall be determined by the following
person or persons, who shall be empowered to make such determination: (i) if a
Change in Control shall have occurred, by Independent Counsel (unless the
Indemnitee shall request in writing that such determination be made by the Board
of Directors (or a committee thereof) in the manner provided for in clause
(b)(ii) of this Section 9) in a written opinion to the Board of Directors, a
copy of which shall be delivered to the Indemnitee; (ii) if a Change in Control
shall not have occurred, (A) by the Board of Directors of the Company, by a
majority vote of a quorum consisting of Disinterested Directors, or (B) if a
quorum consisting of Disinterested Directors is not obtainable, or if a majority
vote of a quorum consisting of Disinterested Directors so directs, by
Independent Counsel in a written opinion to the Board of Directors, a copy of
which shall be delivered to the Indemnitee. The Independent Counsel shall be
selected by the Board of Directors and approved by the Indemnitee. Upon failure
of the Board of Directors to so select, or upon failure of the Indemnitee to so
approve, the Independent Counsel shall be selected by the Chancellor of the
State of Delaware or such other person as the Chancellor shall designate to make
such selection. Such determination of entitlement to indemnification shall be
made not later than 45 days after receipt by the Company of a written request
for indemnification. If the person making such determination shall determine
that the Indemnitee is entitled to indemnification as to part (but not all) of
the application for indemnification, such person shall reasonably prorate such
part of indemnification among such claims, issues or matters. If it is so
determined that Indemnitee is entitled to indemnification, payment to Indemnitee
shall be made within 10 days after such determination.

     10. PRESUMPTIONS AND EFFECT OF CERTAIN PROCEEDINGS. (a) In making a
determination with respect to entitlement to indemnification, the Indemnitee
shall be presumed to be entitled to indemnification hereunder and the Company
shall have the burden of proof in the making of any determination contrary to
such presumption.

     (b) If the Board of Directors, or such other person or persons empowered
pursuant to Section 9 to make the determination of whether the Indemnitee is
entitled to indemnification, shall have failed to make a determination as to
entitlement to indemnification within 45 days after receipt by the Company of
such request, the requisite determination of entitlement to indemnification
shall be deemed to have been made and the Indemnitee shall be absolutely
entitled to such indemnification, absent actual and material fraud in the
request for indemnification or a prohibition of indemnification under applicable
law. The termination of any action, suit, investigation or proceeding described
in Sections 4 or 5 hereof by judgment, order, settlement or conviction, or upon
a plea of nolo contendere or its equivalent, shall not, of itself: (i) create a
presumption that the Indemnitee did not act in good faith and in a manner which
he/she reasonably believed to be in or not opposed to the best interests of the
Company, or, with respect to any criminal action or proceeding, that the
Indemnitee has reasonable cause to believe that the Indemnitee's conduct was
unlawful; or (ii) otherwise adversely affect the rights of the Indemnitee to
indemnification, except as may be provided herein.

     11. ADVANCEMENT OF EXPENSES. Subject to applicable law, all reasonable
Expenses actually incurred by the Indemnitee in connection with any threatened
or pending action, suit or proceeding shall be paid by the Company in advance of
the final disposition of such action, suit

                                       7
<PAGE>

or proceeding, if so requested by the Indemnitee, within 20 days after the
receipt by the Company of a statement or statements from the Indemnitee
requesting such advance or advances. The Indemnitee may submit such statements
from time to time. The Indemnitee's entitlement to such Expenses shall include
those incurred in connection with any proceeding by the Indemnitee seeking an
adjudication or award in arbitration pursuant to this Agreement. Such statement
or statements shall reasonably evidence the Expenses incurred by the Indemnitee
in connection therewith and shall include or be accompanied by a written
affirmation by the Indemnitee of the Indemnitee's good faith belief that the
Indemnitee has met the standard of conduct necessary for indemnification under
this Agreement and an undertaking by or on behalf of the Indemnitee to repay
such amount if it is ultimately determined that the Indemnitee is not entitled
to be indemnified against such Expenses by the Company pursuant to this
Agreement or otherwise. Each written undertaking to pay amounts advanced must be
an unlimited general obligation but need not be secured, and shall be accepted
without reference to financial ability to make repayment.

     12. REMEDIES OF THE INDEMNITEE IN CASES OF DETERMINATION NOT TO INDEMNIFY
OR TO ADVANCE EXPENSES. In the event that a determination is made that the
Indemnitee is not entitled to indemnification hereunder or if the payment has
not been timely made following a determination of entitlement to indemnification
pursuant to Sections 9 and 10, or if Expenses are not advanced pursuant to
Section 11, the Indemnitee shall be entitled to a final adjudication in an
appropriate court of the State of Delaware or any other court of competent
jurisdiction of the Indemnitee's entitlement to such indemnification or advance.
Alternatively, the Indemnitee may, at the Indemnitee's option, seek an award in
arbitration to be conducted by a single arbitrator chosen by the Indemnitee and
approved by the Company, which approval shall not be unreasonably withheld or
delayed. If the Indemnitee and the Company do not agree upon an arbitrator
within 30 days following notice to the Company by the Indemnitee that it seeks
an award in arbitration, the arbitrator will be chosen pursuant to the rules of
the American Arbitration Association (the "AAA"). The arbitration will be
conducted pursuant to the rules of the AAA and an award shall be made within 60
days following the filing of the demand for arbitration. The arbitration shall
be held in Denver, Colorado. The Company shall not oppose the Indemnitee's right
to seek any such adjudication or award in arbitration or any other claim. Such
judicial proceeding or arbitration shall be made de novo, and the Indemnitee
shall not be prejudiced by reason of a determination (if so made) that the
Indemnitee is not entitled to indemnification. If a determination is made or
deemed to have been made pursuant to the terms of Section 9 or Section 10 hereof
that the Indemnitee is entitled to indemnification, the Company shall be bound
by such determination and shall be precluded from asserting that such
determination has not been made or that the procedure by which such
determination was made is not valid, binding and enforceable. The Company
further agrees to stipulate in any such court or before any such arbitrator that
the Company is bound by all the provisions of this Agreement and is precluded
from making any assertions to the contrary. If the court or arbitrator shall
determine that the Indemnitee is entitled to any indemnification hereunder, the
Company shall pay all reasonable Expenses actually incurred by the Indemnitee in
connection with such adjudication or award in arbitration (including, but not
limited to, any appellate proceedings).

     13. NOTIFICATION AND DEFENSE OF CLAIM. Promptly after receipt by the
Indemnitee of notice of the commencement of any action, suit or proceeding, the
Indemnitee will, if a claim in respect thereof is to be made against the Company
under this Agreement, notify the Company in

                                       8
<PAGE>

writing of the commencement thereof. The omission by the Indemnitee to so notify
the Company will not relieve the Company from any liability that it may have to
the Indemnitee under this Agreement or otherwise, except to the extent that the
Company may suffer material prejudice by reason of such failure. Notwithstanding
any other provision of this Agreement, with respect to any such action, suit or
proceeding as to which the Indemnitee gives notice to the Company of the
commencement thereof:

          (a) The Company will be entitled to participate therein at its own
     expense.

          (b) Except as otherwise provided in this Section 13(b), to the extent
     that it may wish, the Company, jointly with any other indemnifying party
     similarly notified, shall be entitled to assume the defense thereof with
     counsel reasonably satisfactory to the Indemnitee. After notice from the
     Company to the Indemnitee of its election to so assume the defense thereof,
     the Company shall not be liable to the Indemnitee under this Agreement for
     any legal or other Expenses subsequently incurred by the Indemnitee in
     connection with the defense thereof other than reasonable costs of
     investigation or as otherwise provided below. The Indemnitee shall have the
     right to employ the Indemnitee's own counsel in such action, suit or
     proceeding, but the fees and Expenses of such counsel incurred after notice
     from the Company of its assumption of the defense thereof shall be at the
     expense of the Indemnitee unless (i) the employment of counsel by the
     Indemnitee has been authorized by the Company, (ii) the Indemnitee shall
     have reasonably concluded that there may be a conflict of interest between
     the Company and the Indemnitee in the conduct of the defense of such action
     and such determination by the Indemnitee shall be supported by an opinion
     of counsel, which opinion shall be reasonably acceptable to the Company, or
     (iii) the Company shall not in fact have employed counsel to assume the
     defense of the action, in each of which cases the fees and Expenses of
     counsel shall be at the expense of the Company. The Company shall not be
     entitled to assume the defense of any action, suit or proceeding brought by
     or on behalf of the Company or as to which the Indemnitee shall have
     reached the conclusion provided for in clause (ii) above.

          (c) The Company shall not be liable to indemnify the Indemnitee under
     this Agreement for any amounts paid in settlement of any action, suit or
     proceeding affected without its written consent, which consent shall not be
     unreasonably withheld. The Company shall not be required to obtain the
     consent of the Indemnitee to settle any action, suit or proceeding which
     the Company has undertaken to defend if the Company assumes full and sole
     responsibility for such settlement and such settlement grants the
     Indemnitee a complete and unqualified release in respect of any potential
     liability.

          (d) If, at the time of the receipt of a notice of a claim pursuant to
     this Section 13, the Company has director and officer liability insurance
     in effect, the Company shall give prompt notice of the commencement of such
     proceeding to the insurers in accordance with the procedures set forth in
     the respective policies.

                                       9
<PAGE>

     The Company shall thereafter take all necessary or desirable action to
     cause such insurers to pay, on behalf of the Indemnitee, all amounts
     payable as a result of such proceeding in accordance with the terms of the
     policies.

     14. OTHER RIGHT TO INDEMNIFICATION. The indemnification and advancement of
Expenses provided by this Agreement are cumulative, and not exclusive, and are
in addition to any other rights to which the Indemnitee may now or in the future
be entitled under any provision of the Bylaws or Certificate of the Company, the
Certificate or Bylaws or other governing documents of any direct or indirect
wholly-owned subsidiary of the Company, any vote of the stockholders or
Disinterested Directors, any provision of law or otherwise. Except as required
by applicable law, the Company shall not adopt any amendment to its Bylaws or
Certificate the effect of which would be to deny, diminish or encumber the
Indemnitee's right to indemnification under this Agreement.

     15. DIRECTOR AND OFFICER LIABILITY INSURANCE. The Company shall, from time
to time, make the good faith determination whether or not it is practicable for
the Company to obtain and maintain a policy or policies of insurance with
reputable insurance companies providing the officers and directors of the
Company, and any direct or indirect wholly-owned subsidiary of the Company, with
coverage for losses from wrongful acts, or to ensure the Company's performance
of its indemnification obligations under this Agreement. Among other
considerations, the Company will weigh the costs of obtaining such insurance
coverage against the protection afforded by such coverage. Notwithstanding the
foregoing, the Company shall have no obligation to obtain or maintain such
insurance if the Company determines in good faith that such insurance is not
necessary or is not reasonably available, if the premium costs for such
insurance are disproportionate to the amount of coverage provided, if the
coverage provided by such insurance is limited by exclusions so as to provide an
insufficient benefit or if the Indemnitee is covered by similar insurance
maintained by a direct or indirect wholly-owned subsidiary of the Company.
However, the Company's decision whether or not to adopt and maintain such
insurance shall not affect in any way its obligations to indemnify its officers
and directors under this Agreement or otherwise. In all policies of director and
officer liability insurance, the Indemnitee shall be named as an insured in such
a manner as to provide the Indemnitee the same rights and benefits as are
accorded to the most favorably insured of the Company's directors, if the
Indemnitee is a director; or of the Company's officers, if the Indemnitee is not
a director of the Company, but is an officer. The Company agrees that the
provisions of this Agreement shall remain in effect regardless of whether
liability or other insurance coverage is at any time obtained or retained by the
Company; except that any payments made to, or on behalf of, the Indemnitee under
an insurance policy shall reduce the obligations of the Company hereunder.

     16. SPOUSAL INDEMNIFICATION. The Company will indemnify the Indemnitee's
spouse to whom the Indemnitee is legally married at any time the Indemnitee is
covered under the indemnification provided in this Agreement (even if the
Indemnitee did not remain married to him or her during the entire period of
coverage) against any pending or threatened action, suit, proceeding or
investigation for the same period, to the same extent and subject to the same
standards, limitations, obligations and conditions under which the Indemnitee is
provided indemnification herein, if the Indemnitee's spouse (or former spouse)
becomes involved in a pending or threatened action, suit, proceeding or
investigation solely by reason of his or her

                                       10
<PAGE>

status as the Indemnitee's spouse, including, without limitation, any pending or
threatened action, suit, proceeding or investigation that seeks damages
recoverable from marital community property, jointly-owned property or property
purported to have been transferred from the Indemnitee to his/her spouse (or
former spouse). The Indemnitee's spouse or former spouse also may be entitled to
advancement of Expenses to the same extent that the Indemnitee is entitled to
advancement of Expenses herein. The Company may maintain insurance to cover its
obligation hereunder with respect to the Indemnitee's spouse (or former spouse)
or set aside assets in a trust or escrow funds for that purpose.

     17. INTENT. This Agreement is intended to be broader than any statutory
indemnification rights applicable in the State of Delaware and shall be in
addition to any other rights the Indemnitee may have under the Company's
Certificate, Bylaws, applicable law or otherwise. To the extent that a change in
applicable law (whether by statute or judicial decision) permits greater
indemnification by agreement than would be afforded currently under the
Company's Certificate, Bylaws, applicable law or this Agreement, it is the
intent of the parties that the Indemnitee enjoy by this Agreement the greater
benefits so afforded by such change.

     18. ATTORNEY'S FEES AND OTHER EXPENSES TO ENFORCE AGREEMENT. In the event
that the Indemnitee is subject to or intervenes in any proceeding in which the
validity or enforceability of this Agreement is at issue or seeks an
adjudication or award in arbitration to enforce the Indemnitee's rights under,
or to recover damages for breach of, this Agreement the Indemnitee, if he/she
prevails in whole or in part in such action, shall be entitled to recover from
the Company and shall be indemnified by the Company against any actual expenses
for attorneys' fees and disbursements reasonably incurred by the Indemnitee.

     19. 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 the Indemnitee, who shall execute all documents required and shall
do all acts that may be necessary to secure such rights and to enable the
Company effectively to bring suit to enforce such rights.

     20. EFFECTIVE DATE. The provisions of this Agreement shall cover claims,
actions, suits or proceedings whether now pending or hereafter commenced and
shall be retroactive to cover acts or omissions or alleged acts or omissions
which heretofore have taken place. The Company shall be liable under this
Agreement, pursuant to Sections 4 and 5 hereof, for all acts of the Indemnitee
while serving as a director and/or officer, notwithstanding the termination of
the Indemnitee's service, if such act was performed or omitted to be performed
during the term of the Indemnitee's service to the Company.

     21. DURATION OF AGREEMENT. This Agreement shall continue until and
terminate upon the later of: (a) ten years after the Indemnitee has ceased to
occupy any of the positions or have any relationships described in Sections 4
and 5 of this Agreement and (b) the final termination of all pending or
threatened actions, suits, proceedings or investigations to which the Indemnitee
may be subject by reason of the fact that he/she is or was a director, officer,
employee, agent or fiduciary of the Company, or any direct or indirect
wholly-owned subsidiary of the Company, or is or was serving at the request of
the Company as a director, officer, employee, agent or fiduciary of any other
entity, including, but not limited to, another corporation, partnership, limited
liability company, employee benefit plan, joint venture, trust or

                                       11
<PAGE>

other enterprise, or by reason of any act or omission by the Indemnitee in any
such capacity. The indemnification provided under this Agreement shall continue
as to the Indemnitee even though he/she may have ceased to be a director or
officer of the Company, or any direct or indirect wholly-owned subsidiary of the
Company. This Agreement shall be binding upon the Company and its successors and
assigns, including, without limitation, any corporation or other entity which
may have acquired all or substantially all of the Company's assets or business
or into which the Company may be consolidated or merged, and shall inure to the
benefit of the Indemnitee and his/her spouse, successors, assigns, heirs,
devisees, executors, administrators or other legal representations. The Company
shall require any successor or assignee (whether direct or indirect, by
purchase, merger, consolidation or otherwise) to all or substantially all of the
business and/or assets of the Company, by written agreement in form and
substance reasonably satisfactory to the Company and the Indemnitee, expressly
to assume and agree to perform this Agreement 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.

     22. DISCLOSURE OF PAYMENTS. Except as expressly required by any federal
securities laws or other federal or state law, neither party hereto shall
disclose any payments under this Agreement unless prior approval of the other
party is obtained.

     23. SEVERABILITY. If any provision or provisions of this Agreement shall be
held invalid, illegal or unenforceable for any reason whatsoever, (a) the
validity, legality and enforceability of the remaining provisions of this
Agreement (including, but not limited to, all portions of any Sections of this
Agreement containing any such provision held to be invalid, illegal or
unenforceable) shall not in any way be affected or impaired thereby and (b) to
the fullest extent possible, the provisions of this Agreement (including, but
not limited to, all portions of any paragraph of this Agreement containing any
such provision held to be invalid, illegal or unenforceable, that are not
themselves invalid, illegal or unenforceable) shall be construed so as to give
effect to the intent manifest by the provision held invalid, illegal or
unenforceable.

     24. COUNTERPARTS. This Agreement may be executed by one or more
counterparts, each of which shall for all purposes be deemed to be an original
but all of which together shall constitute one and the same agreement. Only one
such counterpart signed by the party against whom enforceability is sought shall
be required to be produced to evidence the existence of this Agreement.

     25. CAPTIONS. The captions and headings used in this Agreement are inserted
for convenience only and shall not be deemed to constitute part of this
Agreement or to affect the construction thereof.

     26. ENTIRE AGREEMENT, MODIFICATION AND WAIVER. This Agreement constitutes
the entire agreement and understanding of the parties hereto regarding the
subject matter hereof, and no supplement, modification or amendment of this
Agreement shall be binding unless executed in writing by both 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. No supplement, modification or
amendment to this Agreement shall limit or restrict any right of the Indemnitee
under this Agreement in respect

                                       12
<PAGE>

of any act or omission of the Indemnitee prior to the effective date of such
supplement, modification or amendment unless expressly provided therein.

principles.
