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 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 any 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, amount 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 (iii) 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 asssets 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 repect, 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,
