Loan Papers are being executed and delivered, and are intended to be performed,
in the State of Colorado, and the substantive Laws of such state shall govern
the validity, construction, enforcement, and interpretation of the Loan Papers,
unless otherwise specified therein. Each party consents to the personal
jurisdiction of the state and federal courts located in the State of Colorado in
connection with any controversy related to this Amendment, the Loan Agreement,
or any of the Loan Papers, waives any argument that venue in any such forum is
not convenient and agrees that any litigation initiated by any of them in
connection with this Amendment, the Loan Agreement, or any of the Loan Papers,
shall be venued in either the District Court of the City and County of Denver,
Colorado, or the United States District Court, District of Colorado. Each UK
Subsidiary hereby appoints the Borrower as its authorized agent upon which
notices hereunder or any process may be served in any suit, action or proceeding
arising out of or based on this Amendment or any Loan Papers which are
instituted in any of the aforementioned state or federal courts in Colorado and
expressly accepts the jurisdiction of any court in respect of such action. Such
appointment shall be irrevocable so long as any Obligations remain unpaid unless
and until the appointment of a successor or authorized agent located in Colorado
and notice thereof is give to Bank. Each of the UK Subsidiaries will take any
and all action, including the filing of any and all documents and instruments,
that may be necessary to continue such appointment or appointments in full force
and effect as aforesaid. EACH OF THE UK SUBSIDIARIES HEREBY IRREVOCABLY WAIVES
ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR
RELATING TO THIS AMENDMENT OR THE LOAN AGREEMENT OR THE TRANSACTIONS
CONTEMPLATED HEREBY.

     SECTION 8.3 SEVERABILITY. If any provision of this Amendment or any of the
Loan Papers is held to be illegal, invalid, or unenforceable under present or
future Laws effective during the term thereof, such provision shall be fully
severable; the appropriate Loan Paper shall be construed and enforced as if such
illegal, invalid, or unenforceable provision had never comprised a part thereof;
and the remaining provisions thereof shall remain in full force and effect and
shall not be affected by the illegal, invalid, or unenforceable provision or by
its severance therefrom. Furthermore, in lieu of such illegal, invalid, or
unenforceable provision there shall be added automatically as a part of such
Loan Paper a provision as similar in terms to such illegal, invalid, or
unenforceable provision as may be possible and be legal, valid, and enforceable.

     SECTION 8.4 SURVIVAL. Except as specifically provided herein, all
representations, warranties, covenants and agreements of the UK Subsidiaries
contained herein shall continue in full force and effect so long as any part of
the Obligations remains unpaid and, except as otherwise indicated, shall not be
affected by any investigation made by any party.

     SECTION 8.5 FURTHER ASSURANCES. Each of the UK Subsidiaries agrees that at
any time and

                                       16

from time to time, upon the written request Bank, it will execute and deliver
such further documents and do such further acts and things Bank may reasonably
request in order to fully effect the purpose of this agreement and the other
Loan Papers and to provide for the payment of the principal and interest on the
Obligations in accordance with the terms and provisions of the Loan Papers.

     SECTION 8.6 COUNTERPARTS. This Amendment has been executed in a number of
identical counterparts, each of which, for all purposes, is to be deemed an
original, and all of which constitute, collectively, one Amendment, but, in
making proof of this Amendment, it shall not be necessary to produce or account
for more than one such counterpart.

     SECTION 8.7 FORM OF DOCUMENTS. Each agreement, document, instrument, or
other writing to be furnished to Bank under any provision of this agreement must
be in form and substance satisfactory to Bank and its counsel.


                                       17
