for payment, protest, notice of intent to accelerate, notice of acceleration or
any other notices of any kind, each of which is hereby expressly waived by
Borrower.

            7.2 TERMINATION OF LENDER'S OBLIGATIONS. Lender shall have the right
to immediately terminate and cease performance of any and all of Lender's
obligations under this Agreement, the Master Promissory Note and the Operating
Lease.

            7.3 ASSUMPTION OF DOVER NOTE. Lender shall have the right to either
(i) assume Borrower's obligations under the Dover Note, or (ii) purchase the
Dover Note from the holder of the Dover Note provided the holder consents to
such sale.

            7.4 ADDITIONAL RIGHTS. After any acceleration in accordance with
Section 7.1, Lender shall have, in addition to the rights and remedies provided
by this Agreement and the Master Promissory Note, all those rights and remedies
provided by the Security Instruments and by all applicable laws, including,
without limitation, the Uniform Commercial Code as enacted in the State of
California.

      8. SECURITY INSTRUMENTS. The Indebtedness shall be secured by a
combination of the Stock Pledge Agreement and the Personal Guaranty. Lender may
release all or some portion of the pledged shares upon a written required made
by Joe Allwein provided that (i) no Event of Default has occurred and is
continuing under this Agreement and (ii) Lender is satisfied in its sole and
absolute discretion that the payment of the Indebtedness will be sufficiently
secured after such requested release.

      9.    MISCELLANEOUS.

            9.1 FURTHER ASSURANCE. From time to time, Borrower will execute and
deliver to Lender such additional documents and will provide such additional
information as Lender may reasonably request to carry out the terms of this
Agreement and be informed of Borrower's financial condition and affairs.

            9.2 CUMULATIVE RIGHTS AND WAIVERS. Each and every right granted to
Lender hereunder or under the Master Promissory Note or any Security Instrument
delivered hereunder or in connection herewith, or allowed at law or equity shall
be cumulative of and may be exercised in addition to any and all other rights of
Lender, and no delay or failure in exercising any right shall operate as a
waiver thereof, nor shall any single or partial exercise by Lender of any right
preclude any other or future exercise thereof or the exercise of any other
right. Borrower expressly waives any presentment, demand, protest, or other
notice of any kind. No notice to or demand on Borrower or the Guarantors in any
case shall, of itself, entitle Borrower or the Guarantors to any other or
further notice or demand in similar or other circumstances. No delay or omission
by Lender in exercising any power or right hereunder shall impair any such right
or power or be construed as a waiver thereof or any acquiescence therein, nor
shall any single or partial exercise of any such power preclude other or further
exercise thereof, or the exercise of any other right or power hereunder.

            9.3 USURY. Regardless of any provision contained in this Agreement,
the Master Promissory Note or the Security Instruments, the holder of the Master
Promissory Note shall never be entitled to contract for, charge, receive, take,
collect, reserve or apply as interest on the Master Promissory Note any amount
in excess of the Maximum Rate, and, in the event such holder ever contracts for,
charges, receives, takes, collects, reserves or applies as interest any such
excess, such amount which would be deemed excessive interest shall be subject to
the usury provisions contained in the Master Promissory Note.

            9.4 NOTICES. All notices, requests, demands and other communications

            9.5 AMENDMENT. This Agreement may be amended, modified or
supplemented only by written agreement of the parties hereto.

            9.6 BINDING EFFECT; ASSIGNMENT. This Agreement shall be binding upon
and shall inure to the benefit of the parties hereto and their respective
successors and permitted assigns; provided, however, that neither this Agreement
nor any rights or duties hereunder may be assigned or delegated, as the case may
be, by Borrower without the prior written consent of Lender.

            9.7 HEADINGS. The headings in this Agreement are inserted for
convenience and identification only and are not intended to describe, interpret,
define, or limit the scope, extent, or intent of this Agreement or any provision
thereof.

            9.8 ENTIRE AGREEMENT. This Agreement embodies the entire agreement
and understanding of the parties hereto, and supersedes all prior agreements or
understandings (whether written or oral), with respect to the subject matter
hereof. There are no restrictions, promises, representations, warranties,
covenants or undertakings, other than those expressly set forth or referred to

            9.9 GOVERNING LAW AND VENUE. The validity of this Agreement and any

hereunder, shall be governed by the laws of the State of California (without
regard to its conflicts of law doctrines) and the venue for any action to
enforce or to interpret this Agreement shall be in a court of competent
jurisdiction located in the State of Colorado and each of the parties consents
to the jurisdiction of such court in any such action or proceeding and waives

illegal, invalid or unenforceable provision had never comprised a part hereof;
and the remaining provisions hereof shall remain in full force and effect and

its severance herefrom. Furthermore, in lieu of such illegal, invalid or
unenforceable provision(s) there shall be added automatically as a part of this
Agreement a provision as similar in terms to such illegal, invalid, or
unenforceable provision as may be possible and be legal, valid and enforceable
and that shall not be more restrictive than the one severed herefrom.
