         (ii)     the benefits described in Paragraph 9(b)(v) for the
         Continuation Period, provided that the Continuation Period shall be
         twelve (12) months in the event the Company terminates the Contractor's
         employment for bona fide performance - related reasons (as determined
         by the Board ) and provided further that the Company shall not be
         required to grant any new awards to the Contractor.

employment is terminated as a result of the death of the Contractor, then to the
extent possible the Company shall maintain coverage for the Contractor's
dependents under the Contractor Benefit Plans maintained by the Company,
including without limitation health insurance programs, for a period of six (6)
months as if the Contractor were still an Contractor of the Company. The
foregoing notwithstanding, in the event the Contractor's dependents become or
are eligible for comparable coverage to that set out in the Contractor Benefit
Plans, the coverage provided by the Company under this Subsection (d) shall
terminate immediately.

above, the Contractor shall not be required to mitigate the amount of any
payment contemplated thereby (whether by seeking new employment or in any other
manner) and, except as expressly provided in Paragraph 9(b)(v) and the
corresponding provision in Subsections 9(c) (d), no payment or entitlement under
this Section 9 shall be reduced by earnings that the Contractor may receive from
any other source.

time during the Term and for a period of 1 year thereafter, either directly,

Notwithstanding the foregoing, the Company acknowledges and agrees that the
Contractor is entitled to accept positions on the Board of Directors and
Advisory Boards of other companies so long as such companies are not competitors
of the Company and the performance of duties on behalf of such companies does
not adversely impact on or affect the Contractor's functioning as an Contractor
of the Company.

and/or assets, by an agreement in substance and form satisfactory to the
Contractor, to assume this Agreement and to agree expressly to perform this
Agreement in the same manner and to the same extent as the Company would be
required to perform it in the absence of a succession. The Company's failure to
obtain such agreement prior to the effectiveness of a succession shall be a
breach of this Agreement and shall entitle the Contractor to all of the
compensation, benefits and reimbursements to which he or she would have been
entitled hereunder if the Company had involuntarily terminated his or her
employment without Cause immediately after such succession becomes effective.
For all purposes under this Agreement, the term "Company" shall include any

limitation by bankruptcy, garnishment, attachment or other creditor's process,
and any action in violation of this Subsection 11(b) shall be void.

(c)      Notice - Notices and all other communications contemplated by this
Agreement shall be in writing and shall be deemed to have been duly given when
personally delivered or when mailed by registered or certified mail, return
receipt requested and postage prepaid. In the case of the Contractor, mailed
notices shall be addressed to the Contractor at the most recent home address
provided by the Contractor to the Company in writing. In the case of the
Company, mailed notices shall be addressed to its corporate headquarters, and
all notices shall be directed to the attention of its President.

(d)      Waiver - No provision of this Agreement shall be modified, waived or
discharged (including without limitation the notice periods set out in Section
8) unless the modification, waiver or discharge is agreed to in writing and
signed by the Contractor and by an authorized officer of the Company (other than
the Contractor). No waiver by either party of any breach of, or of compliance
with, any condition or provision of this Agreement by the other party shall be
considered a waiver of any other condition or provision or of the same condition
or provision at another time.

(e)      Whole Agreement - This Agreement (together with any additional
agreements relating to non-competition, confidentiality and inventions, stock
options and Company plans and programs relating to Contractors) constitutes the
entire agreement between the parties, there being no other agreements,

are not expressly set forth herein. This Agreement supersedes all prior written
agreements between the Contractor and the Company.

(f)      No Setoff; Withholding Taxes - With the exception of taxes and other
legally required deductions, Contractor contributions to benefit and other plans

obligation, against any payments to the Contractor under this Agreement.

provisions of this Agreement shall not affect the validity or enforceability of

performance of this Agreement shall be governed by the laws of the Colorado and
the parties attorney to the courts of Colorado USA.
