total net lease (a "net, net, net lease"), whereby the Tenant has the obligation

and repair; the cost of personnel to implement such services; the cost of
maintaining in good working condition the HVAC system(s) for the Leased
premises; the cost of maintaining in good working condition the elevator(s) for
the Leased Premises, if applicable; and costs to cover Landlord's management

less than the estimated costs, the Landlord shall forthwith refund the amount of
the Tenant's excess payment to the Tenant.
    Additionally, upon Lease expiration or termination Landlord shall also
determine Tenant's prorated Prorata Share of the annualized actual costs of the
foregoing expenses for the number of days the Lease is in effect during the
calendar year in which the Lease expires or terminates.  If the annualized
actual costs are greater than the estimated costs, the Tenant shall pay its
prorated Tenant's Prorata Share of the difference between the estimated costs
and the annualized actual costs to the Landlord, or, if the annualized actual
costs are less than the estimated costs, the Landlord shall forthwith refund the
excess to the Tenant.  For purposes of calculating Tenant's share of expenses
under this paragraph, annualized actual costs shall be the sum of actual costs
for the year at the time of reconciliation plus the total estimated costs
prorated for the number of days from the date the last actual cost was paid to
the end of the year.

the property shall not be a breach of this Lease by Landlord nor give rise to

remove all persons and property therefrom, without being liable to indictment,
prosecution for damage therefore, or for forcible entry and detainer and
repossess and enjoy the Leased Premises, together with all additions thereto or
alterations and improvements thereof.  Landlord may, at its option, at any time
and from time to time thereafter, relet the Leased Premises or any part thereof
for the account of Tenant or otherwise, and receive and collect the rents
therefore and apply the same first to the payment of such expenses as Landlord
may have incurred in recovering possession and for putting the same in good
order and condition for rerental, and expense, commissions and charges paid by
Landlord in reletting the Leased Premises.  Any such reletting may be for the
remainder of the term of this Lease or for a longer or shorter period.  In lieu

Lease, the equivalent of the amount of all rent reserved herein and all other
charges required to be paid by Tenant, less the net amount received by Landlord
for such reletting, if any, unless waived by written notice from Landlord to
Tenant.  No action by Landlord to obtain possession of the Leased Premises
and/or to recover any amount due to Landlord hereunder shall be taken as a
waiver of Landlord's right to require full and complete performance by Tenant of
all terms hereof, including payment of all amounts due hereunder or as an
election on the part of Landlord to terminate this Lease Agreement.  If the
Leased Premises shall be reoccupied by Landlord, then, from and after the date
of repossession, Tenant shall be discharged of any obligations to Landlord under
the provisions hereof for the payment of rent.  If the Leased Premises are
reoccupied by the Landlord pursuant hereto, and regardless of whether the Leased
Premises shall be relet or possessed by Landlord, all fixtures, additions,
furniture, and the like then on the Leased Premises may be retained by Landlord.
In the event Tenant is in default under the terms hereof and, by the sole
determination of Landlord, has abandoned the Leased Premises, Landlord shall
have the right to remove all the Tenant's property from the Leased Premises and
dispose of said property in such a manner as determined best by Landlord, at the
sole cost and expense of Tenant and without liability of Landlord for the
actions so taken and without liability on the part of Landlord for any action so
taken.

for the benefit of creditors, or, if the Tenant's leasehold interest under the
terms of this Lease Agreement shall be levied upon by execution or seized by
virtue of any writ of any court of law, or, if application be made for the
appointment of a receiver for the business or property of Tenant, or, if a
petition in bankruptcy shall be filed by or against Tenant, then and in any such
case, at Landlord's option, with or without notice, Landlord may terminate this
Lease and immediately retake possession of the Leased Premises without the same
working any forfeiture of the obligations of Tenant hereunder.
    d. Tenant hereby grants to the Landlord a security interest in and to any
and all of Tenant's property located in, on or adjacent to the Leased Premises
as security for Tenant's full and complete performance of the terms and
conditions of this Lease, which security interest is enforceable by Landlord as
provided by the laws of the State of Colorado.
    e. In addition to all rights and remedies granted to Landlord by the terms
hereof, Landlord shall have available any and all rights and remedies available
at law or in equity, or under the statutes of the State of Colorado.  No remedy
herein or otherwise conferred upon or reserved to Landlord shall be considered
exclusive of any other remedy but shall be cumulative and shall be in addition
to every other remedy given hereunder or now or hereafter existing at law or in
equity or by statute.  Further, all powers and remedies given by this Lease to
Landlord may be exercised, from time to time, and as often as occasion may arise
or as may be deemed expedient. No delay or omission of Landlord to exercise any
right or power arising from any default shall impair any such right or power or
shall be considered to be a waiver of any such default or acquiescence thereof.
The acceptance of rent by Landlord shall not be deemed to be a waiver of any
breach of any of the covenants herein contained or of any of the rights of
Landlord to any remedies herein given.
    f. If Tenant shall, for any reason, vacate the Leased Premises before the
current expiration date, landlord shall have the right to accelerate rental
payments and any and all future rent payments due during the course of the Lease

expenses, including all reasonable attorney's fees incurred by the
non-defaulting party in pursuing such remedy, if such non-defaulting party is
awarded substantially the relief requested.

40. Administrative Charges.  In the event any check, bank draft or negotiable
instrument given for any money payment hereunder shall be dishonored at any time
and from time to time, for any reason whatsoever not attributable to Landlord,
Landlord shall be entitled, in addition to any other remedy that may be
available, (1) to make an administrative charge of $100.00 or three times the
face value of the check, bank draft or negotiable instrument, whichever is
smaller, and (2) at Landlord's sole option, to require Tenant to make all future
rental payments in cash or cashiers check.
