                                       3


The remedies provided in this Note, the Note Purchase Agreement and the Security
Agreement shall be cumulative, and shall be in addition to any other rights or
remedies now or hereafter provided by law or equity. No delay, failure or
omission by Holder or any holder of this Note, in respect of any default by the
Company, to exercise any right or remedy shall constitute a waiver of the right
to exercise the right or remedy with respect to any such default or subsequent
default.

Notice of demand, presentation for payment, notice of nonpayment or dishonor,
protest and notice of protest are hereby waived by the Company. The Company
agrees that the granting, with or without notice, of any extension or extensions
of time for payment of any sum or sums due hereunder, or for the performance of
any covenant, condition or agreement contained herein, or the granting of any
other indulgences to the Company, or any other modifications to or amendment of
this Note, or the acceptance, release or substitution by Holder of any security,
shall in no way release or discharge the liability of the Company.

In the event that (i) the Company issues and sells shares of its capital stock
to investors in a bona-fide arms' length transaction for aggregate consideration
(excluding conversion of any outstanding indebtedness) of at least $5,000,000 (a
"Qualified Offering") and (ii) any principal amount of this Note is then
outstanding or was repaid within 120 days of the closing of such Qualified
Offering, then the Holder shall have the right, but not the obligation, (A) to
convert any unpaid principal and interest then outstanding under this Note into
the same class and series of shares of capital stock that are issued and sold in
the Qualified Offering ("Offered Shares") at a conversion price that is equal to
the lowest per share price paid by the Investors in the Qualified Offering and
(B) to purchase up to that number of Offered Shares with an aggregate purchase
price equal to the amount repaid under this Note during said 120-day period at a
price that is equal to the lowest per share price paid by the Investors in the
Qualified Offering. In each such case, the Offered Shares so acquired by Holder
shall have the same rights and privileges provided to the purchasers in the
Qualified Offering. Upon a conversion or partial conversion of this Note into
shares of the Company's capital stock pursuant to clause (A) of this paragraph,
the Holder shall surrender this Note to the Company. Upon the purchase in the
Qualified Offering of any Offered Shares that the Holder is entitled to purchase
pursuant to the terms of clause (B) of this paragraph, the Holder will pay to
the Company an amount in cash or other immediately available funds equal to the
aggregate purchase price of the shares so purchased. As soon as practicable
thereafter, the Company shall issue and deliver to the Holder a certificate for
the number of shares of capital stock to which it shall be entitled as
aforesaid, together with a cash adjustment in respect of any fraction of a share
if not convertible into a number of whole shares. If this Note is only partially
converted into shares of the Company's capital stock and the remaining principal
and accrued interest hereunder is not paid in full, the Company shall, upon
surrender of this Note, issue to the Holder a replacement promissory note, in
form and substance substantially in the form hereof. The Company shall notify
the Holder in writing not less than ten (10) business days prior to the closing
of a Qualified Offering, specifying the material terms of the Qualified
Offering, the anticipated closing date of the Qualified Offering, and the
identity of the persons and entities then anticipated to purchase shares in the
Qualified Offering. If the Holder intends to convert all or part of this Note or
to purchase shares in the Qualified Offering



                                       4


pursuant to the terms of this paragraph, the Holder shall notify the Company in
writing not less than five (5) business days prior to the anticipated closing
date of such Qualified Offering (as stated in the Company's notice) of its
intent to so acquire shares, which notice shall specify the number of shares the
Holder intends to acquire, and whether and the extent to which such shares will
be acquired by conversion of this Note or pursuant to the purchase rights set
forth above. If the Holder does not deliver notice to the Company according to
the terms of the preceding sentence, the Holder shall forfeit any right it may
otherwise have had to participate in such Qualified Offering.

Anything in this Note to the contrary notwithstanding, no provision of this
Note, whether operating individually or in conjunction with any applicable
provisions of the Note Purchase Agreement, shall require the payment or permit
the collection of interest in excess of the highest rate permitted by applicable
law, and any portion of the interest otherwise payable under this Note, whether
operating individually or in conjunction with any applicable provisions of the
Note Purchase Agreement, which is in excess of the highest rate permitted by
applicable law shall be credited to the principal of this Note, or, if such
principal has been repaid, be refunded to the Company.

If any of the provisions of this Note, the Note Purchase Agreement or the
Security Agreement shall be held to be invalid or unenforceable, the
determination of invalidity or unenforceability of any such provision shall not
affect the validity or enforceability of any other provision or provisions
hereof.

This Note shall be binding upon the Company and its successors and assigns and
shall inure to the benefit of and be enforceable by Holder and its successors
and assigns.

All notices to the Company expressly required in this Note shall be given in
accordance with the terms of the notice provisions of the Note Purchase
Agreement.

This Note shall be construed and enforced in accordance with the laws of the
State of Colorado.
