Indemnified Party's failure to provide any such notice to the Indemnifying Party
will not relieve the Indemnifying Party of or from any of its obligations

amount of any settlement affected without its prior written consent.

                  6.3      Consequential Damages. Except with respect to a
Party's fraud or willful misconduct, and except with respect to damages sought
by a third party in connection with a third party claim, none of the Parties, or
their Affiliates, will be liable to the other Parties, or their Affiliates, for
any damages other than direct damages. Each Party agrees that it is not entitled

                  7.11     Expenses. Except as otherwise provided herein, the
Parties will each pay their own expenses incident to the negotiation,

disbursements of their respective investment bankers, accountants and counsel.

                  7.12     Waiver. No failure on the part of any Party to

thereof, nor will any single or partial exercise preclude any further or other
exercise of such or any other right.

                  7.14     Arbitration; Jurisdiction. Any dispute, controversy
or claim arising under or related to this Agreement, regardless of the legal
theory upon which it is based, will be settled by final, binding arbitration
pursuant to the Federal Arbitration Act, 9 U.S.C. Section 1 et seq., in
accordance with the American Arbitration Association Commercial Arbitration
Rules. Nothing herein will, however, prohibit a Party from seeking temporary or
preliminary injunctive relief in a court of competent jurisdiction. In any
arbitration, the number of arbitrators will be three. If all three Parties to
this Agreement are parties to the arbitration, each of the three Parties shall
have the right to appoint one arbitrator. If only two Parties to this Agreement
are parties to the arbitration, each of the Parties shall have the right to
appoint one arbitrator, who will together appoint a third neutral arbitrator
within thirty (30) days after the appointment of the last party-designated
arbitrator. All arbitration proceedings will take place in Denver, Colorado. The
arbitrators will be entitled to award monetary and equitable relief, including
specific performance and other injunctive relief; provided, however, that only
damages allowed pursuant to this Agreement may be awarded. Except as otherwise
expressly provided in this Section 7.14, each Party will bear the expenses of
its own counsel and will jointly bear the expenses of the arbitrators. The
arbitrators will allocate the remaining costs of the arbitration proceeding. The
Parties agree that the arbitrators will include, as an item of damages, the
costs of arbitration, including reasonable legal fees and expenses, incurred by
the prevailing party if the arbitrators determine that either (a) the
non-prevailing party did not act in good faith when disputing its liability
hereunder to the prevailing party or when initiating a claim against the
prevailing party; or (b) the prevailing party has had to resort to arbitration
with respect to a substantially similar claim more than twice in any thirty-six
(36) month period. Should it become necessary to resort or respond to court
proceedings to enforce a Party's compliance with this Section 7.14, such
proceedings will be brought only in the federal or state courts located in the
State of Colorado, which will have exclusive jurisdiction to resolve any
disputes with respect to this Agreement, with each Party irrevocably consenting
to the jurisdiction thereof. If the court directs or otherwise requires
compliance herewith, then all costs and expenses, including reasonable
attorneys' fees incurred by the Party requesting such compliance, will be
reimbursed by the non-complying Party to the requesting Party.

                  7.15     General Rules of Construction. For all purposes of
this Agreement and the Exhibits and Schedules delivered pursuant to this
Agreement: (i) the terms defined in Article I have the meanings assigned to them
in Article I and include the plural as well as the singular; (ii) all accounting
terms not otherwise defined herein have the meanings assigned under GAAP; (iii)
all references in this Agreement to designated "Articles," "Sections" and other
subdivisions are to the designated Articles, Sections and other subdivisions of
the body of this Agreement; (iv) pronouns of either gender or neuter will
include, as appropriate, the other pronoun forms; (v) the words "herein,"
"hereof" and "hereunder" and other words of similar import refer to this
Agreement as a whole and not to any particular Article, Section or other
subdivision; (vi) "or" is not exclusive; (vii) "including" and "includes" will
be deemed to be followed by "but not limited to" and "but is not limited to,"
respectively; (viii) any definition of or reference to any law, agreement,
instrument or other document herein will be construed as referring to such law,
agreement, instrument or other document as from time to time amended,

supplemented or otherwise modified; and (ix) any definition of or reference to
any statute will be construed as referring also to any rules and regulations
promulgated thereunder.
