Exhibit (10)(g)

                                 Promissory Note

$400,000.00                                                      August 11, 2000

FOR VALUE RECEIVED, the undersigned, PAK MAIL CENTERS OF AMERICA, INC., a
Colorado corporation (the "Maker"), promises to pay to the order of D.P. Kelly &
Associates, L. P., an Illinois limited partnership ("Holder") at 701 Harger
Road, Oak Brook, Illinois, or at any other place designated from time to time by
the Holder, in lawful money of the United States, the principal sum of Four
Hundred Thousand Dollars ($400,000.00) plus interest as hereinafter provided on
the unpaid principal balance outstanding from time to time from the date hereof.

All payments made on account of the indebtedness evidenced by this Note shall be
applied first to accrued and unpaid interest on the unpaid principal balance and
the remainder to principal.

Interest on the unpaid principal balance outstanding from time to time shall
accrue from August 11, 2000 at a rate per annum (calculated on a 360-day year
basis for actual number of days elapsed) equal to the Prime Rate (as herein
defined). Interest on this Note shall be due and payable on the last day of each
month commencing August 31, 2000. The "Prime Rate" means the rate of interest
equal to the prime rate as announced from time to time at Bank One, NA, Chicago,
Illinois (Currently 9.5% per annum). The Prime Rate shall be adjusted quarterly
hereafter on the first (1st) day of each January, April, July and October,
provided, however, such interest rate due under this Note shall at no time
exceed eleven percent (11%) or be less than eight percent (8%).

At the election of the Holder hereof, the principal sum remaining unpaid hereon,
together with accrued interest thereon, shall become at once due and payable at
the place of payment aforesaid in case default shall occur in the payment, when
due, of any installment of principal or interest in accordance with the terms
hereof, and such default shall continue for (3) days after notice by the Holder
to the Maker of such default (in which event election may be made at any time
after the expiration of said three (3) days without notice).

The Maker further agrees to pay all expenses, including reasonable attorneys'
fees and legal expenses incurred by the holder or holders hereof in endeavoring
to collect any amounts payable hereunder which are not paid when due.

Any principal amount not paid when due (upon maturity, acceleration or
otherwise) shall, without notice, bear interest thereafter until paid a rate per
annum which is three (3) percentage points per annum above the Prime Rate but
never less than three (3) percentage points above the Prime Rate in effect when
such principal amount became due (the Default Rate).

Maker hereby waives protest, presentment for payment, demand for payment, notice
of nonpayment, and protest of dishonor, and consents to and waives notice of any
extension, renewal or modification of this Note granted by Holder.
Notwithstanding the foregoing, Holder shall not modify this Note without the
consent of Maker.

<PAGE>

No delay or omission on the part of the Holder is in exercising any remedy,
right or option hereunder shall operate as a waiver of such remedy, right or
option. In any event, a waiver on any one occasion shall not be construed as a
waiver or bar to any such remedy, right or option on a future occasion.

If any payment of principal or interest on this Note shall become due on a
Saturday, Sunday, or public holiday or national banking holiday, such payment
shall be made on the next succeeding business day and, in the case of a
principal payment, such extension of time shall be included in computing
interest in connection with such payment.

The Note may be prepaid in whole or in part at any time upon not less than two
(2) days notice to Holder hereof. Each such prepayment shall be accompanied by
accrued interest on the amount prepaid to the date fixed for prepayment.

IN WITNESS WHEREOF, Pak Mail centers of America, Inc. has caused this Note to be
executed this 11th day of August 2000.

CENTERS OF AMERICA, INC., a Colorado corporation ("Tenant").

                              W I T N E S S E T H :

                                    ARTICLE 1
                                     DEMISE

commonly referred to as PRIMECENTER AT RAMPART situated on that certain real

the exclusive or non-exclusive use of the tenants of the Office Park, all of
which inclusive of all of the buildings in the Office Park are hereinafter
collectively called the "Building Complex". In no event shall any other building
in the Building Complex or the roof of the Building be deemed a portion of the
Premises nor shall Tenant have any rights to access the roof of the Building
without Landlord's prior written consent, which consent may be given or withheld
in Landlord's sole discretion and which consent may impose any conditions to
such access as Landlord deems reasonably necessary to protect the roof from
damage and to otherwise keep and maintain any ongoing warranties.

     Such letting and hiring is upon and subject to the terms, conditions and
covenants herein set forth, and Tenant covenants as a material part of the
consideration for this Lease to keep and perform each and all of said terms,
conditions and covenants by it to be kept and performed and that this Lease is
made upon the condition of such performance.

                                    ARTICLE 2
                                      TERM

     2.1 Term. The term of this Lease and Tenant's obligation to pay rent shall
commence on the earlier to occur of (a) July 15, 1999, or (b) the date upon
which Tenant takes occupancy of the Premises for the purposes of conducting its
business (the "Commencement Date") and shall end at 5:00 p.m. on the last day of

                                       1

<PAGE>

the eighty-fourth (84th) month thereafter, unless extended or sooner terminated
as herein provided (the "Lease Term").

     2.2 Supplemental Agreement. Within five (5) days after the commencement of
the term of this Lease, Tenant agrees to execute a Supplemental Agreement in the
form attached as Exhibit D to become a part hereof, setting forth the
commencement and termination dates of the term of this Lease and such other
information as set forth therein, including the final determination of the
number of usable square feet in the Premises and any corresponding adjustments
hereto.

     2.3 Landlord's Work. Other than as set forth in the Work Letter attached
hereto as Exhibit C, Landlord shall have no obligation for the completion of the
Premises and Tenant shall accept the Premises in its "AS IS" condition as of the
date Landlord delivers possession thereof in accordance with the provisions of
the Work Letter, including any punch list items.

                                    ARTICLE 3
                                      RENT

     3.1 Base Rent. On or before the Commencement Date, Tenant shall elect one
of the two following options for payment of Base Rent during the term of the
Lease:

         OPTION A:

               Tenant agrees to pay as base annual rent (the "Base Rent") during
the first Lease Year of the Term of this Lease the sum of $12.50 per usable
square foot of the Premises per annum, triple net, which equates to
approximately $156,750 per annum payable in equal monthly installments of
$13,062.50, and Base Rent for each Lease Year thereafter shall be payable in
accordance with the schedule set forth below, without notice, deduction, set-off
or abatement to the Landlord at the address of Landlord as set forth in Section
26.1 or at such other address as the Landlord may notify the Tenant of in
writing, in lawful money of the United States payable in advance on the first
day of each month. If the Lease Term commences or terminates on a day other than
the first or last day of a calendar month respectively, then the installments of
Base Rent for such month or months shall be prorated and the installments so
prorated shall be paid in advance. The term "Lease Year" shall mean each twelve
month period subsequent to the Commencement Date.

         Months                       Base Rent Per Usable
                                    Square Foot Per Annum (nnn)
         13 - 24                            $12.75
         25 - 36                            $13.01
         37 - 48                            $13.27
         49 - 60                            $13.53
         61-72                              $13.80
         73-84                              $14.08

                                       2

<PAGE>

         OPTION B:

               Tenant agrees to pay as base annual rent (the "Base Rent") during
the first Lease Year of the Term of this Lease the sum of $12.50 per usable
square foot of the Premises per annum, triple net, in the same manner as set
forth in Option A above, however, Base Rent payments would not commence until
January 1, 2000, with all accrued Base Rent from the Commencement Date to
January 1, 2000 being amortized over the remaining Term of the Lease at ten
percent (10%) per annum, such Base Rent and Base Rent for each Lease Year
thereafter being payable in accordance with the following schedule:

         Months                     Base Rent Per Usable
                                    Square Foot Per Annum
         1- 5                               $-0-
         6 - 12                             $13.58
         13 - 24                            $13.83
         25 - 36                            $14.09
         37 - 48                            $14.35
         49 - 60                            $14.61
         61 - 72                            $14.88
         73 - 84                            $15.16

     3.2 Additional Rent. Any other sums of money or charges to be paid by the
Tenant pursuant to the provisions of this Lease may be designated as "Additional
Rent". A failure to pay Additional Rent shall be treated in all events as the
failure to pay rent.

     3.3 Interest on Late Payments and Late Payment Charge. Any rent (whether
Base Rent or Additional Rent) or other amount due from Tenant to Landlord under
this Lease not paid within five (5) days of the date due shall bear interest
from the date due until the date paid at the rate of two percent (2%) per month
(the "Default Rate"), but the payment of such interest shall not excuse or cure
any default by Tenant under this Lease. Failure to charge or collect such
interest in connection with any one or more such late payments shall not
constitute a waiver of Landlord's right to charge and collect such interest in
connection with any other or similar or like late payments.

     Furthermore, in the event any rent or other amounts owing hereunder are not
paid within five (5) days after the due date, then Landlord and Tenant agree
that Landlord will incur additional administrative expenses, the amount of which
will be difficult if not impossible to determine. Accordingly, in addition to
such required payment, Tenant shall pay to Landlord an additional one time late
charge for any such late payment in the amount of five percent (5%) of the
amount of such late payment. Notwithstanding the above, Landlord agrees that if
Landlord receives payment of such amounts due within five (5) days of Tenant's
written receipt of notice of nonpayment from Landlord, then Landlord shall waive
the interest on such late payment and the late charge, but Landlord (i) shall
have no obligation to waive such charges and interest more than twice during any

                                       3

<PAGE>

calendar year; (ii) shall have not obligation to give notice more than twice
during any calendar year; and (iii) shall have no obligation to waive any
charges if there is any prior existing uncured default under this Lease.

                                    ARTICLE 4
                     TAXES AND OPERATING EXPENSE ADJUSTMENT

     In addition to Base Rent, Tenant shall reimburse Landlord for Real Estate
Taxes and Operating Expenses (which sum may be adjusted pursuant to Section 4.2)
for the Building Complex as hereinafter set forth in this Section.

     4.1 Definitions. The following terms shall have the following meanings with
respect to the provisions of this Section 4.1:

         (a) "Tenant's Proportionate or Prorata Share" shall mean that fraction,
the numerator of which is the Usable Area of the Premises and the denominator of
which is 165,191 square feet being the total Usable Area of the Building Complex
and is equal to 7.5912% which calculation shall be final except as specifically
set forth herein and as same may be adjusted pursuant to the Supplemental
Agreement. At such time, if ever, any space is added to or subtracted from the
Premises as hereinbelow provided, the Tenant's Prorata Share shall be adjusted
accordingly. Landlord's system for measurement of usable area shall be a
modified BOMA with the total Building rentable useable ratio applied to every
floor based upon the Construction Drawings (as defined in the Work Letter) for
the Premises and the Building as determined by Landlord's architect.

         (b) "Real Estate Taxes" shall include (a) any form of assessment
(including any so-called "special" assessments), license tax, business license
fee, business license tax, commercial rental tax, levy, charge, penalty or tax,
imposed by any authority having the direct power to tax, including any city,
county, state or federal government, or any school, agricultural, lighting,
water, drainage or other improvement or special district thereof, against the
Premises, the Building, Property, or Building Complex or any legal or equitable
interest of the Landlord therein; (b) any tax on the Landlord's right to rent or
other income from the Premises or against the Landlord's business of leasing the
Premises; and (c) any assessments, tax, fee, levy or charge in substitution,
partially or totally, of or in addition to any assessment, tax, fee, levy or
charge previously included within the definition of Real Estate Taxes which may
be imposed by governmental agencies for such services as fire protection,
street, sidewalk and road maintenance, refuse removal and for other governmental
services formerly provided without charge to property owners or occupants. It is
the intention of the Landlord and the Tenant that all such new and increased
assessments, taxes, fees, levies and charges be included within the definition
of Real Estate Taxes for purposes of this Lease. The following shall also be
included within the definition of Real Estate Taxes for purposes of this Lease,
provided, however, that the Tenant shall pay the Landlord the entire amount
thereof: (i) any tax allocable to or measured by the area of the Premises or the
rental payable hereunder, including without limitation, any gross income,
privilege, sales or excise tax levied by the State, any political subdivision
thereof, city, municipal or federal government, with respect to the receipt of
such rental, or upon or with respect to the possession, leasing, operating,

the Premises or any portion thereof; and (ii) any tax upon this transaction or

                                       4

<PAGE>

any document to which the Tenant is a party, creating or transferring an
interest or an estate in the Premises. "Real Estate Taxes" shall not include the
Landlord's federal or state income, franchise, inheritance or estate taxes.
"Real Estate Taxes" included in this definition mean taxes or assessments in the
year assessed, without regard to the year in which same become due or payable.

         (c) "Operating Expenses" shall mean all maintenance and operating costs
of any kind or nature with respect to the operation, ownership and maintenance
of the Building and the Building Complex and shall include, but not be limited
to, the cost of building supplies, window cleaning, costs incurred in connection
with all energy sources for the Building such as propane, butane, natural gas,

Building Complex required by any change in the laws, ordinances, rules,
regulations or otherwise which were not in effect on the date the Landlord
obtained its building permit to construct the Building Complex required by any
governmental or quasi-governmental authority having jurisdiction over the
Building Complex which costs shall be amortized over the useful life of the
capital improvements or structural repair; and any costs incurred by the
Landlord in making capital improvements or other modifications to any Building
in the Building Complex or any part thereof, which costs shall be amortized over
the useful life of such improvement or modification with interest at the rate of
ten percent(10%) per annum on the unamortized amount, in accordance with such
reasonable life and amortization schedules as shall be determined by Landlord in
accordance with generally accepted accounting principles. Operating Expenses
shall expressly exclude costs of maintenance and repair reimbursed by insurance
proceeds, alterations or other specific costs attributable solely to other
tenant's space in the Building or Building Complex which were under the
respective terms of the lease such tenant's responsibility and thereupon billed
to such tenants, costs attributable to maintaining the structural integrity of
the foundation, walls and roof, costs of replacing the entire roof, and legal
fees for financing, sales of the Building Complex, preparing and enforcing
leases and any other legal fees which do not specifically relate to the
operation and maintenance of the Building Complex.

     4.2 Payments of Taxes and Operating Expenses. It is hereby agreed that
during each Lease Year of the Lease Term hereof, the Tenant shall pay to the
Landlord Tenant's Prorata Share of the amount of the Operating Expenses and Real
Estate Taxes for the Building Complex, with appropriate and equitable adjustment
for Variable Operating Expenses. It is agreed that the Tenant shall, during each
calendar year, including the calendar year in which the term of this Lease
commences, pay to the Landlord an estimate of the Tenant's Prorata Share of such
Real Estate Taxes and Operating Expenses as hereinafter set forth. Beginning
with the calendar year in which this Lease commenced, the Tenant shall pay to

                                       5

<PAGE>

the Landlord each month on the first day of the month an amount equal to
one-twelfth (1/12) of Tenant's Prorata Share of the Real Estate Taxes and
Operating Expenses for the new calendar year as reasonably estimated by the
Landlord, with an adjustment to be made between the parties at a later date as
hereinafter provided. Furthermore, Landlord may from time to time but no more
than three (3) times during any Lease Year furnish Tenant with notice of a
re-estimation of the Real Estate Taxes and Operating Expenses and Tenant shall
commence paying its re-estimated Prorata Share on the first day of the month
following receipt of said notice. As soon as practicable following the end of
any calendar year but in no event later than April 15th, the Landlord shall
submit to the Tenant a statement setting forth the exact amount of the Tenant's
Prorata Share of the Real Estate Taxes and Operating Expenses for the calendar
year just completed and the difference, if any, between the Tenant's actual
Prorata Share of the Real Estate Taxes and Operating Expenses for the calendar
year just completed and the estimated amount of the Tenant's Prorata Share of
the Real Estate Taxes and Operating Expenses (which were paid in accordance with
this subparagraph) for such year. Such statement shall also set forth the amount
of the estimated Real Estate Taxes and Operating Expenses reimbursement for the
new calendar year computed in accordance with the foregoing provisions. To the
extent that the Tenant's Prorata Share of the actual Real Estate Taxes and
Operating Expenses for the period covered by such statement are higher than the
estimated payments which the Tenant previously paid during the calendar year
just completed, the Tenant shall pay to the Landlord the difference within
thirty (30) days following receipt of said statement from the Landlord. To the
extent that the Tenant's Prorata Share of the actual Real Estate Taxes and
Operating Expenses for the period covered by the Statements are less than the
estimated payments which the Tenant previously paid during the calendar year
just completed, the Landlord may at its option either refund said amount to
Tenant or credit the difference against the Tenant's estimated reimbursement for
such Real Estate Taxes and Operating Expenses for the current year. In addition,
with respect to the monthly reimbursement, until the Tenant receives such
statement, the Tenant's monthly reimbursement for the new calendar year shall
continue to be paid at the then current rate, but the Tenant shall commence
payment to the Landlord of the monthly installments of reimbursement on the
basis of the statement beginning on the first day of the month following the
month in which Tenant receives such statement.

         The Tenant's obligation with respect to its Prorata Share of the Real
Estate Taxes and Operating Expenses shall survive the expiration or early
termination of this Lease and the Landlord shall have the right to retain the
Security Deposit, or so much thereof as it deems necessary, to secure payment of
the Tenant's Prorata Share of the actual Real Estate Taxes and Operating
Expenses for the portion of the final calendar year of the Lease during which
the Tenant was obligated to pay such expenses. If the Tenant occupies the
Premises for less than a full calendar year during the first or last calendar
years of the term hereof, the Tenant's Prorata Share for such partial year shall
be calculated by proportionately reducing the Real Estate Taxes and Operating
Expenses to reflect the number of months in such year during which Tenant
occupied the Premises. The Tenant shall pay its Prorata Share within thirty (30)
days following receipt of notice thereof.

         The Tenant shall have the right but not more than once per annum, at
any time within thirty (30) days after a statement of actual Real Estate Taxes
and Operating Expenses for a particular calendar year has been rendered by the

                                       6

<PAGE>

Landlord as provided herein, at Tenant's sole cost and expense, to examine the
Landlord's books and records during normal business hours (upon reasonable prior
written notice to Landlord), at Landlord's office relating to the determination
of such Real Estate Taxes and Operating Expenses. Unless Tenant objects to the
statement provided by Landlord, within said thirty (30) day period, such
statement and adjustment shall be deemed conclusive.

     4.3 Reimbursement Survives Termination. In the event of the termination of
this Lease by expiration of the stated term or for any other cause or reason
whatsoever prior to the determination of rental adjustment as hereinafter set
forth, the Tenant's agreement to reimburse Landlord up to the time of
termination shall survive termination of the Lease and the Tenant shall pay any
amount due to the Landlord within fifteen (15) days after being billed therefor.
In the event of the termination of this Lease by expiration of the stated term
or for any other cause or reason whatsoever, except default by the Tenant of any
of the terms or provisions of this Lease, prior to the determination of rental
adjustments as hereinabove set forth, the Landlord's agreement to refund any
excess additional rental paid by the Tenant up to the time of termination shall
survive termination of the Lease and the Landlord shall pay the amount due to
the Tenant within fifteen (15) days of the Landlord's determination of such
amount. This covenant shall survive the expiration or termination of this Lease.

         If the last year of the term of this Lease ends on any day other than
the last day of December, any payment due to the Landlord by reason of any
increase in Real Estate Taxes and Operating Costs shall be prorated on the basis
by which the number of days in such partial year bears to 365.

         Any failure of Landlord to furnish Tenant with an estimate of its
Prorata Share of Real Estate Taxes and Operating Expenses or any statements as
set forth in this Section 4 shall not act to relieve Tenant of its liability
therefor; and with respect to any deficiencies, Tenant agrees to pay same within
thirty (30) days of written demand from Landlord.

     4.4 Triple Net Lease. This Lease is "triple net" and all costs and expenses
of any kind or nature are to be borne by Tenant except as specifically set forth
as exclusions in the last sentence of Section 4.1(c) above.

     4.5 Building Complex. Landlord may from time to time add additional
buildings to the Building Complex, in which event Tenant's Pro Rata Share shall
be adjusted accordingly when each building is leased and occupied.

                                    ARTICLE 5
                                UTILITY SERVICES

     5.1 Utility Services. The Premises shall be separately metered for gas and
electricity, the costs for installation of such meters to be paid from the
Allowance as defined in Exhibit C hereof. Tenant agrees to pay directly to the
respective utility company for all such metered utilities prior to delinquency.
Landlord shall provide domestic water in reasonable quantity and Tenant shall
pay its Pro Rata Share thereof as an Operating Expense in accordance with

                                       7

<PAGE>

Article 4 hereof. Tenant acknowledges that all costs or expenses of any kind or
nature arising from or related to the heating, ventilation and air conditioning
(HVAC) system shall be borne by Tenant; however, Landlord shall oversee HVAC
preventative maintenance service for the HVAC system servicing Tenant's
Premises, which costs shall be billed to Tenant from time to time by Landlord
during the Lease Term and shall be paid by Tenant within thirty (30) days of
receipt of such written demand therefor. Tenant agrees to keep, maintain and
operate the HVAC in good condition and repair at Tenant's sole cost in
accordance with any warranties or rules or regulations promulgated by Landlord
from time to time concerning operation, maintenance and repair thereof.
Notwithstanding any of the above, the HVAC system and other mechanical systems
shall be part of the Building and the property of Landlord.

     5.2 Interruption of Utility Services. Tenant agrees that Landlord shall not
be liable for any interruption of any heating, air conditioning, electric
current, water, gas or any other utility service (or any failure to supply same,
as applicable) if restoration of such services or electric current is within
Landlord's reasonable control and Landlord uses reasonable diligence to restore
or supply such services or electric current. It is further agreed that Landlord
reserves the right to temporarily discontinue any services at such times as may
be necessary by reason of accident, unavailability of employees, repairs,
alterations, or improvements, or whenever by reason of strikes, lockouts, riots,
acts of God or any other happening or occurrence beyond the reasonable control
of Landlord. If any utility services are interrupted, Landlord shall not be
liable for damages to persons or property for any such discontinuance, nor shall
such discontinuance in any way be construed as a constructive or actual eviction
of Tenant or cause an abatement of rent or operate to release Tenant from any of
Tenant's obligations hereunder. Landlord's obligation, if any, to furnish any
utility services shall be conditioned upon the availability of adequate sources
from the public utility companies presently serving the Building Complex. If
Landlord elects in its reasonable discretion to temporarily discontinue utility
services to Tenant and/or the Building Complex then Landlord shall use
reasonable efforts to restore as soon as possible any utility service which has
been interrupted. Landlord shall have the right to reduce lighting in the public
area in the Building Complex as required by any mandatory fuel or energy-saving
program or architectural control committee or as otherwise required by law.
Tenant hereby acknowledges that Landlord shall have no responsibility or
liability for the HVAC system other than to enforce any manufacturer's
warranties applicable thereto and Landlord makes no representations or
warranties with respect to such HVAC system. Notwithstanding the foregoing,
Landlord hereby agrees that if there is an interruption or discontinuance of the
services which Landlord has agreed to provide that renders the Premises
untenantable and such interruption or discontinuance is within Landlord's
reasonable control and continues for a period of ten (10) or more consecutive
days after Landlord receives written notice thereof from Tenant (hereinafter
referred to as an "Unauthorized Interruption"), Tenant's rent shall abate,
provided Landlord can recover such rent through Landlord's rent loss/business
interruption insurance covering the Building, commencing at the end of said ten
(10) day period and continuing until such time as the Premises are rendered
tenantable, if Landlord has failed to correct or remediate the cause of such
Unauthorized Interruption within such ten day period. In any case, if the
Unauthorized Interruption is the result of any willful misconduct or negligent
acts on the part of Tenant, its agents or employees, or due to Tenant's default,
Tenant's rent shall not abate. If Tenant continues to nonetheless use any part
of the Premises for conducting its business, the rent shall abate only in
proportion to the part rendered untenantable and not so used. Furthermore, if

                                       8

<PAGE>

Landlord's rent loss/business interruption insurance will only cover a portion
of Tenant's rent, the rent shall abate only as to the portion covered by such
insurance.

     5.3 Other Services Paid by Tenant. Unless otherwise provided by Landlord,
Tenant shall separately arrange with the applicable local public authorities or
utilities or other service providers, as the case may be, for the furnishing of
and payment for all other services including all telephone services and other
services for the Premises as may be required by Tenant in the use of the
Premises. Tenant shall directly pay for such telephone services, including the
establishment and connection thereof, at the rates charged for such services by
said authority or utility, and the failure of Tenant to obtain or to continue to
receive such services for any reason whatsoever shall not relieve Tenant of any
of its obligations under this Lease.

     5.4 Above-Standard Service Requirements. If unusual heat-generating
machines or equipment cause the temperature in the Premises, or any part
thereof, to exceed the temperatures the HVAC system would be able to maintain in
such Premises were it not for such heat generating equipment, then Landlord
reserves the right to install supplementary air conditioning units in the
Premises, and the cost thereof, including the cost of installation and the cost
of operation and maintenance thereof, shall be paid by Tenant to Landlord upon
demand by Landlord.

         Tenant shall not, without the written consent of Landlord, connect with
electric current (except through existing electrical outlets in the Premises) or
water pipes any apparatus or device for the purposes of using electric current,
other energy or water except as set forth in Article 15 hereof.

     5.5 Cleaning. Landlord agrees to furnish to the Premises during regular
business hours, except holidays, as determined by Landlord, and subject to the
rules and regulations of the Building, trash removal services. Tenant shall,
however, provide its own janitorial or cleaning services, at Tenant's sole cost,
liability and responsibility, and by a janitorial or cleaning contractor or
employees at all times satisfactory to Landlord and Tenant's Prorata Share of
Operating Expenses for such items shall be adjusted accordingly. Tenant agrees
to comply with such rules and regulations as Landlord may promulgate from time
to time concerning janitorial and trash removal and storage. Tenant shall
promptly notify Landlord of the name of its janitorial cleaning company, as same
may be retained from time to time. The janitorial company shall be insured with
such coverage and companies as are reasonably acceptable to Landlord. Prior to
any janitorial company commencing services, reasonable evidence of such
insurance shall be provided to Landlord. The approval of Landlord and/or the
presence of insurance shall not relieve Tenant from any liability to Landlord
under this Lease arising from or related to such service providers.

                                    ARTICLE 6
                                  TENANT REPAIR

     6.1 Damage by Tenant. If the Building Complex, the Building, the Premises
or any portion thereof including but not limited to the HVAC system, pipes and
other apparatus, or members of elements of the Building (or any of them) used
for the purpose of climate control of the Building, or if the water pipes,

                                       9

<PAGE>

drainage pipes, electric lighting or other equipment of the Building or the roof
or outside walls of the Building or parking facilities of Landlord and also the
Tenant Finish including but not limited to the carpet, wall covering, doors and
woodwork, become damaged or are destroyed through the negligence, carelessness
or misuse of the Tenant, its servants, agents, employees or anyone permitted by
Tenant to be in the Building, or through it or them, then the cost of the
necessary repairs, replacements or alterations shall be borne by the Tenant who
shall forthwith pay the same on demand to the Landlord as Additional Rent.
Landlord shall have the exclusive right, but not the obligation, to make any
repairs necessitated by such damage.

     6.2 Maintenance. Tenant shall keep the Premises in as good order, condition
and repair as when they were entered upon. If Tenant fails to keep the Premises
in such good order, condition and repair as required hereunder to the
satisfaction of Landlord, Landlord may restore the Premises to such good order
and condition and make such repairs without liability to Tenant for any loss or
damage that may accrue to Tenant's property or business by reason thereof
(unless caused by the gross negligence or willful misconduct of Landlord), and
upon completion thereof, Tenant shall pay to Landlord, as Additional Rent, upon
demand, the cost of restoring the Leased Premises to such good order and
condition and of the making of the repairs.

     6.3 Good Condition. Tenant shall keep the Premises in reasonable good and
clean condition and shall also keep and cause its employees, agents, contractors
and invitees to keep the common areas of the Building Complex in clean
condition.

     6.4 Surrender. Tenant shall deliver, at the expiration of the Term hereof
or upon sooner termination of the Term, the Premises in good repair as aforesaid
and in a state of broom cleanliness.

     6.5 Broken Glass. Tenant shall pay on demand the cost of replacement with
identical quality, size and characteristics of glass broken on the Premises,
including outside windows and doors of the perimeter of the Leased Premises
(including perimeter windows in the exterior walls) during the continuance of
this Lease, unless the glass shall be broken by Landlord, its servants,
employees or agents acting on its behalf or is due to structural Building
problems not caused by Tenant, its servants, agents, employees or invitees.

                                    ARTICLE 7
                            ASSIGNMENT AND SUBLETTING

     7.1 Limitations. Tenant shall not sublet, assign or in any manner transfer
this Lease or any estate or interest in the Premises or any part thereof, or
grant any license, concession or other right to occupy any portion of the
Premises without the prior written consent of Landlord as set forth herein.
Landlord shall not unreasonably withhold or delay consent to any subletting or
assignment provided Tenant requests such consent in writing at least fifteen
(15) days prior to the proposed assignment or subletting and (i) Tenant is not
in default of this Lease, (ii) the use of the Premises does not violate the
Lease, including the Rules and Regulations attached thereto, (iii) the proposed
sublessee or assignee has a good business reputation, (iv) Tenant submits and
Landlord approves the most current audited financials for such sublessee or
assignee, (v) Tenant submits the form of assignment or sublease for Landlord's
prior reasonable review and approval, and (vi) such sublessee or assignee is not

                                       10

<PAGE>

a tenant in the Building. In no event shall Tenant have any right to sublet or
assign if there exists any default under this Lease. Consent by Landlord to one
or more sublettings or assignments of this Lease or of the Premises shall not
operate as a waiver of Landlord's rights under this section. Any such assignment
or subletting without Landlord's consent shall be deemed void and confer no
rights upon a third party. Notwithstanding any subletting or assignment, Tenant
and any guarantor of Tenant's obligations under this Lease shall at all times
remain fully responsible and liable for the payment of the rental herein
specified and for compliance with all other terms and conditions of this Lease.
Without in any way limiting Landlord's right to refuse to give consent, Landlord
reserves the right in the event it does give consent to impose such reasonable
conditions upon its consent as Landlord deems necessary including the
requirement of additional security which in Landlord's business judgment shall
insure the state of the Premises and the rentals due under this Lease. Landlord
shall also have the right in the event of such proposed subletting or assignment
to terminate this Lease in whole or in part, in which event Landlord shall have
the right, but not the obligation, to enter into a Lease with such proposed
sublessee or assignee.

         Neither this Lease nor any interest therein shall be assignable as to
the interest of Tenant by operation of law, without the written consent of
Landlord. A sale by Tenant of all or substantially all of its assets or all or
substantially all of its stock, if Tenant is a publicly traded corporation, a
merger of Tenant with another corporation; or the transfer of twenty-five
percent (25%) or more of the stock of Tenant if Tenant's stock is not publicly
traded; or the transfer of fifty percent (50%) or more of the beneficial
ownership interest in Tenant if Tenant is a partnership without the prior
written consent of Landlord, shall constitute a prohibited assignment hereunder,
subject to the limitations set forth above.

     7.2 Acceptance of Performance. If this Lease be assigned or if the Premises
or any part thereof be sublet or occupied by anybody other than Tenant, Landlord
may, after default by Tenant, collect the rent from the assignee, subtenant or
occupant and apply the net amount collected to the rent herein reserved
retaining the remainder, if any, for the account of Landlord, but no such
assignment, subletting, occupancy or collection shall be deemed an acceptance of
the assignee, subtenant or occupant as the Tenant hereof, or constitute a
release of Tenant from further performance by Tenant of the covenants on the
part of Tenant herein contained.

     7.3 Document Review. All documents utilized by Tenant to evidence any
subletting or assignment for which Landlord's consent has been requested, shall
be subject to prior reasonable approval by Landlord or its attorney. Tenant
shall pay on demand all of Landlord's reasonable costs and expenses, including
reasonable attorney's fees, incurred in determining whether or not to consent to
any requested subletting or assignment and for the review and approval of such
documentation. Landlord agrees that such reasonable costs and expenses will not
exceed $500.00 per request provided Tenant uses Landlord's form of assignment or
sublease, without modification.

     7.4 Affiliated Entities. Provided Tenant is not in default hereunder,
Tenant may sublet or assign to any Affiliated Entity (as defined below) without
Landlord's prior consent provided Tenant delivers to Landlord a copy of the
executed sublease or assignment on a Landlord approved form to Landlord within
ten (10) days of such subletting or assignment, which subletting or assignment

                                       11

<PAGE>

shall be subject to all of the liabilities and obligations set forth herein and
Tenant shall not be released of any of its liabilities hereunder. In no event,
however, in the event of an assignment shall such assignment have any material
adverse financial impact on Tenant's financial status. Tenant shall, prior to
such transfer, provide written evidence reasonably satisfactory to Landlord that
there shall be no material adverse financial impact on Tenant or Landlord
resulting from such assignment. For purposes hereof, Affiliated Entity shall
mean an entity which (i) controls, is controlled by, or is in common control
with Tenant; or (ii) results from the merger or consolidation with Tenant or
acquires all or substantially all of the assets or stock of Tenant.

                                    ARTICLE 8
                   TRANSFER BY LANDLORD AND LIMITED LIABILITY

     8.1 Transfer of Landlord's Interest. In the event of a sale, conveyance, or
assignment by Landlord of Landlord's interest in the Building Complex (other
than a transfer for security purposes only), Landlord shall be relieved from and
after the date specified in any such notice of transfer or assignment of all of
Landlord's obligations and liabilities accruing thereafter on the part of
Landlord, and Tenant agrees to look only toward such assignee or transferee of
Landlord's interest.

     8.2 Limited Liability of Landlord. Anything contained in this Lease to the
contrary notwithstanding, Tenant agrees that Tenant shall look solely to the
estate of Landlord in the Building Complex for the collection of any judgment
(or other judicial process) requiring the payment of money by Landlord in the
event of any default or breach by Landlord with respect to any of the terms and
provisions of this Lease to be observed or performed by Landlord, subject,
however, to the prior rights of the holder of any mortgage covering the Building
Complex, and no other assets of Landlord, its partners, agents, employees,
officers, or employees or officers of any of its partners shall be subject to
levy, execution or other judicial process for the satisfaction of Tenant's claim
and Landlord shall not be liable for any such default or breach except to the
extent of Landlord's estate in the Building Complex.

                                    ARTICLE 9
                             USE OF LEASED PREMISES

     9.1 Use. Except as expressly permitted by prior written consent of the
Landlord, the Leased Premises shall not be used other than for general business
office purposes, including, but not limited to, a training facility and for
shipping and receiving of office products. Any other use shall require
Landlord's prior written consent, which shall not be unreasonably withheld
provided that such use complies with applicable restrictive covenants and
zoning, the use is consistent with a first class suburban office building, and
does not generate, store, use, or dispose of any hazardous, toxic or infectious
substances in or from the Premises. All use of the Premises shall comply with
the terms of this Lease and all applicable laws, ordinances, regulations or
other governmental ordinances from time to time in existence.

     9.2 Compliance with Rules and Regulations. Tenant and employees and all
persons visiting or doing business with the Tenant in the Leased Premises shall
be bound by and shall observe the reasonable Rules and Regulations as set forth
in Exhibit E, attached hereto and made a part hereof, which may, at Landlord's

                                       12

<PAGE>

sole discretion, be promulgated, amended, or expanded from time to time during
the Lease term by the Landlord relating to the Building, the Building Complex
and/or the Premises of which notice in writing shall be given to the Tenant
within thirty (30) days of such clause at which time they will become effective
and all such rules and regulations as changed from time to time shall be deemed
to be incorporated into and form a part of this Lease. Any default in the
performance or observance of such rules and regulations shall be a default
hereunder and Landlord shall have all remedies provided for in this Lease in the
event of default by Tenant, Landlord however, shall not be responsible to Tenant
for nonobservance by any other tenant or person of any tenant or person of any
such rules and regulations.

                                    ARTICLE 10
                                    INSURANCE

     10.1 Tenant's Insurance. Tenant shall, during its occupancy of the Premises
and during the entire term hereof, at its sole cost and expense, obtain,
maintain and keep in full force and effect, and with Tenant, Landlord, any
subsequent purchaser of the Building when and if applicable, the property
manager and mortgagees of Landlord named as additional insureds therein as their
respective interests may appear, the following types and kinds of insurance:

         (a) Upon all personal property in, on or about the Premises and upon
all other property of every description and kind owned by Tenant and located in
the Building Complex or for which Tenant is legally liable or installed by or on
behalf of Tenant, including, without limitation, furniture, fittings,
installations, alterations, additions, partitions, fixtures and anything in the
nature of a trade fixture in an amount not less than the full replacement cost
thereof, with a Minimum Coverage on the Special Causes of Loss Form including
Sprinkler Leakage; and in the event that there shall be a dispute as to the
amount which comprises full replacement cost, the decision of Landlord or the
mortgagees of Landlord shall be conclusive. In no event shall the deductible for
such insurance be more than $1,000.00.

         (b) Bodily Injury Property Damage and Commercial General Liability
insurance including personal liability, contractual liability, non-owned
automotive liability, tenants' legal liability for the full replacement costs of
the Premises, and owners' and contractors' protective insurance coverage and a
cross-liability clause with respect to the Premises and Tenant's use of any part
of the Building Complex and which coverage shall include the business operations
conducted by Tenant and any other persons on the Premises. Such policies shall
be written on a comprehensive basis with limits of not less than $2,000,000.00
with respect to injuries or death of one or more persons, and not less than
$1,000,000.00 with respect to property damage and not less than $1,000,000.00
for any one occurrence, together with not less than a $2,000,000 umbrella
policy, and such higher limits for all such insurance as Landlord or the
mortgagees of Landlord may reasonably require. All policies shall name Landlord,
its managers and mortgagee as additional insureds. All policies shall be primary
and noncontributing over any valid and collectible insurance of any of the
additional insureds.

                                       13

<PAGE>

         (c) Any other form or forms of insurance as Landlord or the mortgagees
of Landlord may reasonably require from time to time in form, in amounts and for
insurance risks consistent with then prevalent insurance industry practices and
policies.

         (d) Business interruption insurance in such amounts as will reimburse
Tenant for direct or indirect loss of earnings attributable to all perils
commonly insured against by prudent tenants or attributable to prevention of
access to the Premises or to the Building as a result of such perils.

         (e) Workers' Compensation Insurance and Employers liability insurance
in amounts reasonably satisfactory to Landlord or as required by law.

         (f) If Tenant performs any work on the Premises, prior to the
commencement of any such work, Tenant shall deliver to Landlord certificates
issued by insurance companies qualified to do business in the State of Colorado,
evidencing that workmen's compensation and public liability insurance and
property damage insurance, all with companies in form and in amounts
satisfactory to Landlord, are in force and effect and maintained by all
contractors and subcontractors engaged by Tenant to perform such work and shall
name Landlord, its manager and mortgagee as additional insureds. Landlord or its
mortgagee may require any other form or types of insurance of such parties, and
may be added as an additional insured thereunder if so requested. All policies
shall be primary and noncontributory over any valid collectible insurance made
available to any of the additional insureds.

     All policies shall be taken out with insurers acceptable to Landlord and in
form satisfactory from time to time to Landlord. Tenant agrees that certificates
of insurance, or, if required by Landlord or the mortgagees of Landlord,
certified copies of each such insurance policies will be delivered to Landlord
as soon as practicable after the placing of the required insurance, but in no
event later than ten (10) days after Tenant takes possession of all or any part
of the Premises. All policies shall contain an undertaking by the insurers to
notify Landlord and the mortgagees of Landlord in writing not less than sixty
(60) days prior to any material change, cancellation or sooner termination
thereof.

     Tenant covenants and agrees that in the event of damage or destruction to
the leasehold improvements in the Premises covered by insurance as required to
be taken out by Tenant herein, and if Landlord or Tenant do not terminate this
Lease pursuant to Section 21.1 herein, Tenant will use the proceeds of such
insurance for the purpose of repairing or restoring such leasehold improvements.
In the event that Landlord or Tenant are entitled to terminate the Lease
pursuant to Article 21, then if the Premises have also been damaged, Tenant
shall pay to Landlord that amount of its insurance proceeds necessary to repair
the leasehold improvements.

     10.2 Landlord's Insurance. Landlord agrees to carry during the term hereof
insurance for fire, extended coverage, vandalism and malicious mischief,
insuring the Building Complex (excluding foundations, excavations and other
non-insurable items) for the full insurable value thereof. Landlord may, but
shall not be obligated to, take out and carry any other form or forms of
insurance as it or the mortgagees of Landlord may reasonably determine to be
advisable. All costs of such insurance shall be included as Operating Expenses
and notwithstanding any contribution by Tenant to the cost of insurance

                                       14

<PAGE>

premiums, as provided in Article 4, Tenant acknowledges that it has no right to
receive any proceeds from any such insurance policies carried by Landlord, and
that such insurance will be for the sole benefit of Landlord, with no coverage
for Tenant for any risk insured against.

     10.3 Subrogation. The parties hereto agree that any and all fire, extended
coverage and/or property damage insurance which is required to be carried by
either shall be endorsed with a subrogation clause, substantially as follows:
"This insurance shall not be invalidated should the insured waive, in writing
prior to a loss, any and all right of recovery against any party for loss
occurring to the property described therein"; and each party hereto waives all
claims for recovery from the other party, its officers, agents or employees for
any loss or damage (whether or not such loss or damage is caused by negligence
of the other party), and notwithstanding any provisions contained in this Lease
to the contrary, as a result of damage to any of its real or personal property
insured under valid and collectible insurance policies to the extent of the
collectible recovery under such insurance or which would have been collectible
had the party carried the insurance required to be maintained hereunder.

provided by Landlord to Tenant hereunder, to show the same to prospective

                           INDEMNIFICATION OF LANDLORD

     14.1 Tenant's Indemnity. Tenant shall indemnify the Landlord and save it
harmless from and against any and all loss (including loss of rentals payable by
the Tenant or other tenants in the event of loss either directly or indirectly
caused by any act or omission of Tenant unless such loss is covered by
Landlord's rent abatement insurance), claims, actions, damages, liability and

thereof, or occasioned wholly or in part by any act or omission of the Tenant,

invitees or by anyone permitted to be on Premises by the Tenant; however in no
event shall Tenant indemnify Landlord or hold it harmless from the gross
negligence or misconduct of Landlord, its agents, employees or contractors or

                                   ALTERATIONS

     15.1 Alterations by Tenant. Tenant shall not make, install or erect in or
to the Premises any installations, alterations, additions or partitions without
obtaining the Landlord's prior written consent in each instance, which consent
shall not be unreasonably withheld. Tenant shall also obtain the Landlord's
prior written consent to any change or changes in drawings or specifications,
and Tenant shall pay the cost to the Landlord of having its architects and/or
consultants review such plans and changes thereto prior to proceeding with any
work based on such drawings or specifications. All such work shall be performed
free and clear of all mechanic's liens and Landlord shall have no liability for
the performance of such work, notwithstanding its consent to any plans and
specifications. PROVIDED NEVERTHELESS that the Landlord may, at its option, at
Tenant's expense, require that the Landlord's contractors be engaged for any
mechanical or electrical work. Without limiting the generality of the foregoing,
any work performed by or for the Tenant shall be performed by competent workmen
whose labor union affiliations are not incompatible with those of any workmen
who may be employed in the Building Complex by the Landlord, its contractors or
subcontractors and all work shall be subject to the inspection and reasonable
review and approval by Landlord and/or its consultants. In addition to the above
all contractors and subcontractors must meet Landlord's specifications, as
solely determined by Landlord, for minimum requirements for insurance, bonds,
quality of work, experience and such other reasonably applicable factors. The
Tenant shall submit to the Landlord's supervision over construction, shall
provide Landlord upon request with financial assurances prior to the
commencement of alterations, and promptly pay to the Landlord's or the Tenant's
subcontractors, as the case may be, when due, the costs of all such work and of
all materials, labor and services involved therein and of all decoration and all
changes in the Building, its equipment or services necessitated thereby. The
Tenant covenants that the Tenant will not suffer or permit during the Term
hereof any mechanics' or other liens for work, labor, services or materials
ordered by the Tenant or for the cost of which the Tenant may be in any way
obligated, to attach to the Premises, to the Building or to the Building Complex
and that whenever and so often as any such liens shall attach or claims therefor
shall be filed, the Tenant shall, within thirty (30) days after the Landlord has
notice of the filing of the claim for lien, procure the discharge thereof by
payment or by giving security or in such other manner as is or may be required
or permitted by law or which shall otherwise satisfy Landlord and/or Landlord's
lender. The Tenant shall, at its own cost and expense, take out or cause to be
taken out any additional insurance or bonds reasonably required by the Landlord
to protect the Landlord's and the Tenant's interest during the period of
alteration.

         At least five (5) days prior to the commencement of any work permitted
to be done by persons requested by the Tenant on the Premises, the Tenant shall
notify the Landlord of the proposed work and the names and addresses of the
persons supplying labor and materials for the proposed work so that the Landlord
may avail itself of the provisions of statutes such as Section 38-22-105(2) of
the Colorado Revised Statutes (1973). During any such work on the Premises, the
Landlord, or its representatives, shall have the right to go upon and inspect

                                       17

<PAGE>

the Premises at all reasonable times, and shall have the right to post and keep
posted thereon notices such as those provided for by Section 38-22-105(2) C.R.S.
(1973) or to take any further action which the Landlord may deem to be proper
for the protection of the Landlord's interest in the Premises.

     15.2 Alterations by Landlord. Landlord hereby reserves the right at any
time and from time to time to make changes in, additions to, subtractions from
or rearrangements of the Building Complex, including, without limitation, all
improvements at any time thereof, all entrances and exits thereto, and to grant,
modify and terminate easements or other agreements pertaining to the use and
maintenance of all or parts of the Building and to make changes or additions to
the pipes, conduits, ducts, utilities and other necessary building services in
the Premises which serve other portions of the Building or the Building Complex,
provided that prior to the Commencement Date, the Landlord may alter the
Premises to the extent found necessary by the Landlord to accommodate changes in
construction design or facilities including major alterations but provided
always that the Premises, as altered, shall be in all material aspects
comparable to the Premises as defined herein. Landlord shall not unreasonably
obstruct or interrupt Tenant's access to the Premises and in such event Landlord
shall provide alternative access during all business hours. If Landlord elects
to block Tenant's access during non-business hours for non-emergencies, then
Landlord shall reasonably coordinate same with Tenant.

                              SIGNS AND ADVERTISING

     Except as set forth below, Tenant shall not install, paint, display,
inscribe, place or affix any sign, picture, advertisements, notice, lettering or
direction on any part of the Building Complex or in the interior of the Premises
or other portion of the Building any of which would be visible from outside the
Premises. With the prior written consent of Landlord, Landlord will permit one
sign on the door which constitutes the main entry, and one internally lit sign
up to 44 square feet in size located at the South and East fascia of the
Building and signage on the monument directory sign located nearest the Premises
pursuant to the sign criteria attached as Exhibit H, such rules and regulations
concerning placement, maintenance and removal of such signage as promulgated
from time to time by Landlord and pursuant to all laws, regulations and
ordinances of any applicable governmental authorities and the Rampart
Architectural Control Committee. Tenant shall not install, paint, display,
inscribe, place or affix, or otherwise attach, any sign, picture, advertisement,
notice, lettering or direction on the inside or outside of the Premises for
exterior view without the written consent of Landlord.

                  SUBORDINATION TO MORTGAGES AND DEEDS OF TRUST

     This Lease and the rights of Tenant hereunder shall be and are hereby made
subject and subordinate to the lien of any mortgages or deeds of trust now or
hereafter existing against the Building Complex and to all renewals,
modifications, consolidations, replacements and extensions thereof and to all
advances made, or hereafter to be made, upon the security thereof. Although such
subordination shall be self-operating, Tenant, or its successors in interest,
shall upon Landlord's request, execute and deliver upon the demand of Landlord
any and all instruments desired by Landlord, subordinating, in the manner
reasonably requested by Landlord, this Lease to any such mortgage or deed of

                                       18

<PAGE>

trust. Landlord is hereby irrevocably appointed and authorized as agent and
attorney-in-fact of Tenant to execute all such subordination instruments in the
event Tenant fails to execute said instruments within thirty (30) days after
notice from Landlord demanding the execution thereof.

         Should any mortgage or deed of trust affecting the Building Complex be
foreclosed, then:

         (a) the liability of the mortgagee, beneficiary or purchaser at such
foreclosure sale shall exist only so long as such mortgagee, beneficiary or
purchaser is the owner of the Building Complex and such liability shall not
continue or survive after further transfer of ownership; and

         (b) Tenant shall be deemed to have attorned, as Tenant under this
Lease, to the purchaser at any foreclosure sale thereunder, and this Lease shall
continue in full force and effect as a direct lease between and binding upon
Tenant and such purchaser at any foreclosure sale.

         As used in this Article 17 "mortgagee" and "beneficiary" shall include
successors and assigns of any such party, whether immediate or remote, the
purchaser of any mortgage or deed of trust, whether at foreclosure or otherwise,
and the successors, assigns and mortgagees and beneficiaries of such purchaser,
whether immediate or remote.

         Landlord, at the written request of Tenant, agrees to request any
mortgagee or beneficiary to enter into a non- disturbance agreement with Tenant,
in a form satisfactory to such mortgagee or beneficiary, stating that Tenant's
right to the continued use and possession of the Premises shall be under the
same terms and conditions as set forth in this Lease provided that at such time
Tenant is not in default of its obligations herein. Landlord makes no
representations or warranties that such non-disturbance agreement will be
entered into by any beneficiary or mortgagee, however, the self-operative
subordination of this Lease and attornment by Tenant is in such event
conditioned upon the mortgagee or beneficiary not disturbing Tenant's right
under this Lease, provided that Tenant is not in default hereof.

                   ESTOPPEL CERTIFICATE/FINANCIAL INFORMATION

     18.1 Estoppel Certificate. Tenant agrees that it will from time to time,
upon request by Landlord, execute and deliver to Landlord within ten (10) days
after demand therefor an estoppel certificate on Landlord's form as attached
hereto as Exhibit G, certifying that this Lease is unmodified and in full force
and effect (or if there have been modifications, that the same is in full force
and effect as so modified).

     18.2 Financial Information. Tenant shall, upon Landlord's written request,
deliver to Landlord a copy of Tenant's most recent financial statement, which
annual financial statement shall be prepared and reviewed by an independent
certified public accountant no less often than once per year in accordance with
generally accepted accounting principals ("GAAP").

                                 QUIET ENJOYMENT

     Subject to the terms and provisions of this Lease, Landlord covenants and
agrees that Tenant shall peaceably and quietly enjoy the Premises and Tenant's
rights hereunder during the term hereof, without hindrance by Landlord or those
claiming rights by or through Landlord.

                                   ARTICLE 20
                                    FIXTURES

     Any or all installations, alterations, additions, partitions and fixtures
in or upon the Premises other than the Tenant's trade fixtures, work stations
with movable walls, mounted video screens, raised platforms and cables beneath
the raised platforms, which are located upon the Premises, whether placed there
by the Tenant or the Landlord, shall, immediately upon such placement, become
the property of the Landlord without compensation therefor to the Tenant.
Notwithstanding anything herein contained, the Landlord shall be under no
obligation to repair, maintain or insure such installations, alterations,
additions, partitions and fixtures or anything in the nature of a leasehold
improvement made or installed by or on behalf of the Tenant. Unless otherwise
agreed to in writing, the Landlord may elect that any or all installations made
or installed by or on behalf of the Tenant be removed at the end of the Lease
Term and, if the Landlord so elects, it shall be the Tenant's obligation to
restore the Premises to the conditions they were in previous to such
alterations, installations, partitions and fixtures on or before the termination
of this Lease. Such removal and restoration shall be at the sole expense of the
Tenant.

                                   ARTICLE 21
                              DAMAGE OR DESTRUCTION

     21.1 Casualty. In the event that the Building should be totally destroyed
by fire, tornado or other casualty, or should be so damaged that rebuilding or
repairs cannot be completed within one hundred and eighty (180) days after the
date of such damage, Landlord may, at its option, terminate this Lease in which
event the rent shall be abated during the unexpired portion of this Lease
effective with the date of such damage, or Landlord may proceed to rebuild the
Building and the Premises. If the damage prohibits Tenant's use of the Premises,
cannot be repaired within one hundred and eighty days and was not caused by the
Tenant, then Tenant can elect to terminate this Lease by written notice to
Landlord received within sixty (60) days of the date of damage. In the event the
Building should be damaged by fire, tornado or other casualty, but only to such
extent that rebuilding or repairs in Landlord's reasonable estimation can be
completed within one hundred and eighty (180) days after the date of such
damage, or if the damage cannot be repaired within such time frame but Landlord
does not elect to terminate this Lease, in either such event, Landlord shall,
within sixty (60) days after the date of such damage commence to rebuild or
repair the Building and shall proceed with reasonable diligence to restore the
Building to substantially the same condition in which it was immediately prior
to the happening of the casualty, except that the Landlord shall not be required
to rebuild, repair or replace any part of the partitions, fixtures and other
improvements which may have been placed by the Tenant or other tenants within
the Building and rent shall equitably abate from the date of damage until such
damage is repaired if such casualty results in damage to Tenant's Premises or

                                       20

<PAGE>

prohibits its access to the Premises or use thereof. In the event any mortgagee
under a deed of trust, security agreement or mortgage on the Building should
require that the insurance proceeds be used to retire the mortgage debt,
Landlord shall have no obligation to rebuild and if Landlord so elects, this
Lease shall terminate upon notice to Tenant. Unless otherwise provided in this
Lease, any insurance which may be carried by the Landlord or the Tenant against
loss or damage to the Building or to the Premises shall be for the sole benefit
of the party carrying such insurance and under its sole control.

     21.2 Casualty Caused by Tenant. If fire or other casualty causing injury to
the Premises or other parts of the Building shall have been caused by the
negligence or misconduct of the Tenant, its agents, servants or employees, or by
any other persons entering the Building under express or implied invitation of
the Tenant, such injury may be reasonably repaired by the Landlord at the
reasonable expense of the Tenant.

                                   ARTICLE 22
                                  CONDEMNATION

     22.1 Eminent Domain. If any part of the Usable Area of the Premises is
taken by eminent domain, or by conveyance in lieu thereof then this Lease, at
the option of either party evidenced by notice to the other given within thirty
(30) days from such taking or conveyance, shall forthwith cease and terminate
entirely. In the event of such termination of this Lease, then rental shall be
due and payable to the actual date of such termination. If neither party
terminates this Lease, this Lease shall cease and terminate as to that portion
of the Premises so taken as of the date of such taking, and the rental
thereafter payable under this Lease shall be abated prorata from the date of
such taking in an amount by which that portion of the Usable Area of the
Premises so taken shall bear to the Usable Area of the Premises prior to such
taking. If any part of the Building Complex shall be taken by eminent domain, or
by conveyance in lieu thereof, and if such taking substantially interferes with
the Landlord's ownership or use of the Building Complex, the Landlord, at its
option, may upon thirty (30) days' notice to the Tenant, terminate this Lease as
of the date of such taking.

     22.2 Damages. All compensation awarded for any taking (or the proceeds of
private sale in lieu thereof) of the Premises or Building Complex shall be the
property of Landlord and Tenant hereby assigns its interest in any such award to
Landlord; provided, however, Landlord shall have no interest in any award made
to Tenant for the taking of Tenant's fixtures and other personal property or
moving expenses if a separate award for such items is made to Tenant.

     22.3 Restoration. If both Landlord and Tenant elect not to terminate this
Lease, Tenant shall remain in that portion of the Premises which shall not have
been appropriated or taken as herein provided, and Landlord agrees, at
Landlord's sole cost and expense (not to exceed the amount of condemnation
proceeds received by Landlord), to, as soon as reasonably possible, restore the
remaining portion of the Premises to a complete unit of like quality and
character as existed prior to such appropriation or taking.

                            LOSS AND DAMAGE AND DELAY

     23.1 Loss and Damage. The Landlord shall not be liable or responsible in
any way for:

         (a) any death or injury arising from or out of any occurrence in, upon
or at the Building Complex or for damage to property of the Tenant or others
located on the Premises, nor shall it be responsible in any event for damage to
any property of the Tenant or others from any cause whatsoever, unless such
damage, loss, injury or death results from the intentional misconduct or gross
negligence of the Landlord, its agents, servants or employees acting within the
scope of their employment. Without limiting the generality of the foregoing, the
Landlord shall not be liable for any injury or damage to persons or property
resulting from fire, explosion, falling plaster, steam, gas, electricity, water,
rain, snow or leaks from any part of the Premises or from the pipes, appliances,
plumbing works, roof, street, or subsurface of any floor or ceiling or from any
other place or because of dampness or climatic conditions from any other cause
of whatsoever kind. The Landlord shall not be liable for any damage whatsoever
caused by any other tenant or persons in or about the Building Complex, or by an
occupant of adjacent property thereto, or the public, or construction of any
private, public or quasi-public work. Tenant shall be responsible for all
security within the Premises and at the entrance to the Premises, if any, and
all property of the Tenant kept or stored on the Premises shall be kept or
stored at the risk of the Tenant only and the Tenant shall indemnify the
Landlord in the event of any claims arising out of damages to the same,
including any subrogation claim by the Tenant's insurers;

         (b) any act or omission (including theft, malfeasance or negligence) on
the part of any agent, contractor or person from time to time employed by the
Landlord to perform janitor services or security services, or repairs or
maintenance services, in or about the Premises or the Building; or

         (c) loss or damage, however caused, to money, securities, negotiable
instruments, papers or other valuables of the Tenant.

     23.2 Delays. Whenever and to the extent that the Landlord shall be unable
to fulfill, or shall be delayed or restricted in the fulfillment of, any
obligation hereunder in respect to the supply of or provision for, any service
or utility or the doing of any work or the making of any repairs by reason of
being unable to obtain the material, goods, equipment, service, utility or labor
required to enable it to fulfill such obligation or by reason of any statute,
law or any regulation or order passed or made pursuant thereto or by reason of
the order or direction of any governmental or quasi-governmental administrator,
controller or board, or any governmental department or officer or other
authority, or by reason of not being able to obtain any permission or authority
required thereby, or by reason of any other cause beyond its control, whether of
the foregoing character or not, the Landlord shall be entitled to extend the
time for fulfillment of such obligation by a time equal to the duration of such
delay or restriction, and the Tenant shall not be entitled to compensation for
any inconvenience, nuisance or discomfort thereby occasioned.

then Tenant shall not be in default so long as it has commenced to cure within
fifteen (15) days and is diligently prosecuting same to completion.

         (c) Tenant or any guarantor of Tenant's obligations under this Lease
shall die, cease to exist as a corporation or partnership or be otherwise

following remedies without any notice or demand whatsoever except as required by
applicable law:

         (a) Terminate this Lease, in which event Tenant shall immediately

without prejudice to any other remedy which it may have for possession or

claim of damages therefor.

                                       23

<PAGE>

         (b) Enter upon and take possession of the Premises and expel or remove
Tenant and any other person who may be occupying such Premises or any part
thereof, by force if necessary pursuant to applicable law, without being liable
for prosecution or any claim for damages therefor (except for acts in violation
of law), and relet the Premises and receive the rent therefor.

         (c) Enter upon the Premises, by force if necessary pursuant to
applicable law, without being liable for prosecution or any claim for damages
therefor (except for acts in violation of law), and do whatever Tenant is
obligated to do under the terms of this Lease; and Tenant agrees to reimburse
Landlord on demand for any expenses which Landlord may incur in thus effecting
compliance with Tenant's obligations under this Lease, and Tenant further agrees
that Landlord shall not be liable for any damages resulting to the Tenant from
such action, unless caused by the gross negligence of Landlord.

         (d) Alter all locks and other security devices at the Premises pursuant
to applicable law without terminating this Lease.

         Exercise by Landlord of any one or more of the remedies hereunder
granted or otherwise available shall not be deemed to be an acceptance of
surrender of the Premises by Tenant, whether by agreement or by operation of
law, it being understood that such surrender can be effected only by the written
agreement of Landlord and Tenant. No such alteration of locks or other security
devices and no removal or other exercise of dominion by Landlord over the
property of Tenant or others at the Premises shall be deemed unauthorized or
constitute a conversion, Tenant hereby consenting, after any event of default,
to the aforesaid exercise of dominion over Tenant's property within the
Premises. All claims for damages by reason of such reentry and/or repossession
and/or alteration of locks or other security devices are hereby waived, as all
claims for damages by reason of any distress warrant, forcible detainer
proceedings, sequestration proceedings or other legal process, to the extent
permitted by law. Tenant agrees that any reentry by Landlord may be pursuant to
judgment obtained in forcible detainer proceedings or other legal proceedings or
without the necessity for any legal proceedings, as Landlord may elect, and
Landlord shall not be liable in trespass or otherwise, to the extent permitted
by law.

         In the event Landlord elects to terminate the Lease by reason of an
event of default then notwithstanding such termination, Tenant shall be liable
for and shall pay to Landlord, at the address specified for notice to Landlord
herein, the sum of all rental and other indebtedness accrued to date of such
termination, plus, as damages, an amount equal to the total rental hereunder for
the remaining portion of the Lease term (had such term not been terminated by
Landlord prior to the date of expiration as stated herein), less the reasonable
rental value thereof, plus a sum equal to any other damages incurred by Landlord
by reason of such default.

         In the event that Landlord elects to repossess the Premises without
terminating the Lease, then Tenant shall be liable for and shall pay to Landlord
at the address specified for notice to Landlord herein, all rental and other
indebtedness accrued to the date of such repossession, plus rent required to
paid by Tenant to Landlord during the remainder of the Lease term until the date
of expiration of the term as stated herein diminished by any net sums thereafter

                                       24

<PAGE>

received by Landlord through reletting the Premises during such period (after
deducting expenses incurred by Landlord as provided below). In no event shall
Tenant be entitled to any excess of any rental obtained by reletting over and
above the rental herein reserved. Actions to collect amounts due by Tenant to
Landlord under this subparagraph may be brought from time to time, on one or
more occasions, without the necessity of Landlord's waiting until expiration of
the Lease term.

         In the event of any default or breach by Tenant, or threatened or
anticipatory breach or default, Tenant shall also be liable and shall pay to
Landlord, in addition to any sums provided to be paid above, broker's fees
incurred by Landlord in connection with reletting the whole or any part of the
Premises; the costs of removing and storing Tenant's or other occupants'
property; the costs of repairing, altering, remodeling, or otherwise putting the
Premises into condition acceptable to a new tenant or tenants; and all
reasonable expenses incurred by Landlord in enforcing or defending Landlord's
rights and/or remedies, including reasonable attorney's fees whether suit was
actually filed or not.

         In the event of termination or repossession of the Premises for an
event of default, Landlord shall not, except as set forth herein, have any
obligation to relet or attempt to relet the Premises or any portion thereof, or
to collect rental after reletting; and in the event of reletting, Landlord may
relet the whole or any portion of the Premises for any period to any tenant and
for any use or purpose. Landlord agrees to use reasonable efforts to mitigate
its damages, however, Landlord shall have no obligation to expend sums, give the
Premises priority over other vacant space nor to lease the space on less than
market terms.

         If Tenant shall fail to make any payment or cure any default hereunder
within the time herein permitted, Landlord, without being under any obligation
to do so and without thereby waiving such default, may make such payment and/or
remedy such other default for the account of Tenant (and enter the Premises for
such purpose), and thereupon Tenant shall be obligated to, and hereby agrees to
pay Landlord upon demand all costs, expenses and disbursements, including
reasonable attorney's fees incurred by Landlord in taking such remedial action.

         Landlord is entitled to accept, receive in cash or deposit any payment
made by Tenant for any reason or purpose or in any amount whatsoever, and apply
the same at Landlord's option to any obligation of Tenant and the same shall not
constitute payment of any amount owed except that to which Landlord has applied
the same. No endorsement or statement on any check or letter of Tenant shall be
deemed an accord and satisfaction or recognized for any purpose whatsoever. The
acceptance of any such check or payment shall be without prejudice to Landlord's
rights to recover any and all amounts owed by Tenant hereunder and shall not be
deemed to cure any other default nor prejudice Landlord's rights to pursue any
other available remedy.

     24.3 Landlord's Default. Landlord shall not be deemed in default hereunder
unless Tenant shall have given Landlord written notice of such default
specifying such default with particularity and Landlord shall thereupon have
thirty (30) days in which to cure any default unless such default cannot
reasonably be cured within such period wherein Landlord shall not be in default
if it commences to cure the default within the thirty (30) day period and

                                       25

<PAGE>

diligently pursues completion of same. In the event of any default, Tenant
agrees that its exclusive remedy shall be an action for damages.

     If the Tenant shall continue to occupy and continue to pay rent for the
Premises after the expiration of this Lease with or without the consent of the
Landlord, and without any further written agreement, the Tenant shall be a
tenant from month to month at a monthly Base Rent for the first three (3) months
following the expiration of this Lease, equal to the greater of (i) the market
rate at such time for comparable space in Arapahoe County, Colorado (the "Market

Rent payment due hereunder, and subject to all of the additional rentals, terms
and conditions herein set out except as to expiration of the Lease Term and the
greater of (i) the Market Rate or (ii) two hundred percent (200%) of the last
full monthly Base Rent payment due in the holdover period for any months
thereafter. Such holding over may be terminated by the Landlord or the Tenant
upon fifteen (15) days' notice. In the event that the Tenant fails to surrender
the Premises upon termination or expiration of this Lease or such month to month
tenancy, then the Tenant shall indemnify the Landlord against loss or liability
resulting from any delay of the Tenant in not surrendering the Premises,
including, but not limited to, any amounts required to be paid to third parties
who were to have occupied the Premises and any attorney's fees related thereto.

                                SECURITY DEPOSIT

     Tenant shall deposit with Landlord on or before the date of execution
hereof by Tenant the sum of Eighteen Thousand Three Hundred Eighty-One and
55/100 Dollars ($18,381.55) as security for the performance by Tenant of all of
the terms, covenants, and conditions required to be performed by it hereunder.
Such sum shall be returned to Tenant after a reasonable period after the
expiration of the Lease Term and delivery of possession of the Premises to
Landlord if, at such time, Tenant has fully performed all such terms, covenants
and conditions. Prior to the time when Tenant is entitled to the return of the
security deposit, Landlord shall be entitled to intermingle such deposit with
its own funds and to use same for such purposes as Landlord may determine. In
the event of default by Tenant in performing any of its obligations under this
Lease, Landlord may, in addition to any other right or remedy available to
Landlord hereunder, use, apply, or retain all or any part of this security
deposit for the payment of any unpaid rent or for any other amount which
Landlord may be required to expend by reason of the default of Tenant, including
any damages or deficiency in the reletting of the Premises or any attorney's
fees associated therewith, regardless of the whether the accrual of such damages
or deficiency occurs before or after an eviction. If a portion of the security
deposit is used or applied by Landlord during the term hereof, Tenant shall,
upon five (5) days written demand, deposit with Landlord an amount sufficient to
restore the security deposit to its original amount. Landlord shall return the
security deposit (or that portion of the security deposit not previously
applied) within thirty (30) days after the later of expiration of the lease term
or surrender by Tenant of the Premises without default.

         In addition to the foregoing, Tenant may, at its option, deposit an
additional Eight-Five Thousand Dollars ($85,000) with Landlord to be used by
Landlord at Tenant's discretion.

placed of record. In addition, if requested by the Landlord, the Tenant will
execute a memorandum of lease to be filed with the Colorado Department of
Revenue on such form as may be prescribed by said department within ten (10)
days after the execution of this Lease or any other such memorandum so that the
Landlord may avail itself of the provisions of the statutes such as Section

dealt with any broker in connection with this Lease, and that insofar as Tenant
knows, no other broker negotiated or participated in the negotiations of this
Lease, or submitted or showed the Premises, or is entitled to any commission in
connection herewith and Tenant agrees to indemnify Landlord against any
liability arising from a breach of this representation and warranty including
reasonable attorney's fees. Landlord shall have no obligation to pay any

                              ADDITIONAL PROVISIONS

     33.1 Option to Extend. Tenant shall have an option to extend the Lease for
one (1) additional consecutive term of five (5) years (the "Extended Term"). In
order to exercise such option, Tenant shall notify Landlord in writing at least
nine (9) months prior to the expiration of the Lease Term of its election to
exercise the option (and shall provide to Landlord at such time Tenant's most
recent financials which shall be reasonably acceptable to Landlord), upon which
time Landlord shall submit in writing within 30 days thereafter a proposal for
the then current Market Base Rental Rate (per usable square foot per annum) for
the Extended Term. Tenant shall have thirty (30) days from the receipt of said
notice to (i) accept the proposed Base Rental Rate in writing to Landlord or
(ii) elect not to extend. If Tenant elects not to extend or fails to timely

                                       29

<PAGE>

exercise its option, time being of the essence, the options shall automatically
terminate and be of no further force and effect and this Lease shall terminate
upon expiration of the then Lease Term. Any such extension shall be upon all of
the terms, conditions and covenants of this Lease except as to (i) the amount of
Base Rent, which shall be determined as set forth herein, (ii) other than as
remain applicable under this Lease, options to extend, expand or rights of
refusal, which shall not be applicable, and (iii) Tenant Allowances or other
economic concessions which shall not be applicable to the Extension Term. As
used herein, "Market Base Rental Rate" shall mean the then Base Rental Rate for
comparable first class multi-tenant office buildings of comparable size,
location and age, with comparable tenants leasing comparable amounts of space,
in the County of Arapahoe, Colorado, at such time, taking into account the
following factors (1) rent per usable square foot; (2) operating expenses and
real estate tax payments; (3) current rental escalators; and (4) rental
concessions, including tenant improvement allowances, if any, as applicable to
market renewals of leases.

     33.2 Parking. Landlord will make available to Tenant within the Building
Complex four (4) non-exclusive parking spaces for every 1000 usable square feet
of space in the Premises, including handicapped and visitor spaces. Landlord
agrees to designate no more than five (5) parking spaces (at such location
reasonably determined by Landlord) as "Pak Mail Visitor" spaces. Such spaces
shall be so marked by Landlord, but at Tenant's sole cost and expense. All
parking spaces shall be in and out, non-assigned parking spaces and shall be
free of charge for the Lease Term and Extended Term. Notwithstanding the above,
the right granted to Tenant to use such spaces is a license only and Landlord's
inability to make such spaces available at any time for reasons beyond
Landlord's control is not a material breach by Landlord of its obligations
hereunder. All vehicles parked in the parking areas and the personal property
therein shall be at the sole risk of Tenant and the users of such spaces and
Landlord shall have no liability for loss or damage thereto for whatever cause.

     33.3 Vacation. Tenant may vacate the Premises in whole or in part provided
Tenant (a) gives Landlord thirty (30) days prior written notice of its intent to
vacate, (b) complies with all other terms of the Lease including payment of Base
Rent and Additional Rent, (c) continually uses good faith efforts to either
obtain occupants for the Premises or reoccupy the Premises, and (d) Tenant keeps
the Premises lit and otherwise continues to give the appearance that the
Premises are occupied (but no on-site personnel shall be required).

     IN WITNESS WHEREOF, the parties hereto have executed this Lease this ______
day of May, 1999.

                                   WORK LETTER

     This WORK LETTER ("Work Letter") is entered into as of the ____ day of May,
1999, by and between GEDDES STREET, LLC, a Colorado limited liability company
("Landlord"), and PAK MAIL CENTERS OF AMERICA, INC., a Colorado corporation
("Tenant").

     R E C I T A L S:

A. Concurrently with the execution of this Work Letter, Landlord and Tenant have
entered into a lease (the "Lease") covering certain premises (the "Premises")
more particularly described in Exhibit A attached to the Lease. To the extent
applicable, the provisions of the Lease are incorporated herein by this
reference.

B. In order to induce Tenant to enter into the Lease and in consideration of the
mutual covenants hereinafter contained, Landlord and Tenant agree as follows:

1.   TENANT IMPROVEMENTS. As used in the Lease and this Work Letter, the term
"Tenant Improvements" or "Tenant Improvement Work" means those items of general
tenant improvement construction shown on the Construction Documents (described
in Paragraph 4 below), more particularly described in Paragraph 5 below.

2.   WORK SCHEDULE. Attached to this Exhibit C is a schedule ("Work Schedule")
which sets forth a timetable of critical dates for the planning and completion
of the installation of the Tenant Improvements and the Commencement Date of the
Lease. The Work Schedule describes certain of the critical items of work to be
done or approval to be given by Landlord and Tenant in connection with the
completion of the Tenant Improvements. All plans and drawings required by this
Work Letter and all work performed pursuant thereto are to be prepared and
performed in accordance with the Work Schedule. Based upon developments during
construction of the Tenant Improvements, the parties may modify the Work
Schedule as appropriate to reflect changes to the Work Schedule agreed to by the
parties and changes to the Work Schedule resulting from Tenant Delays or Force
Majeure Delays and Landlord caused delays.

3.   TENANT CONSTRUCTION REPRESENTATIVES. Landlord hereby appoints the following
person(s) as Landlord's representative ("Landlord's Representative") to act for
Landlord in all matters covered by this Work Letter: Ron McInroy, telephone
(303) 741-0700, facsimile (303) 741-6988. Tenant is entitled to rely on
information and decisions of Landlord's Representative, and the signature of
Landlord's Representative on documents, change orders and other instruments
delivered in connection with this Work Letter, shall be conclusive evidence of
Landlord's approval.

                                       C-1

Tenant hereby appoints the following person(s) as Tenant's representative
("Tenant's Representative") to act for Tenant in all matters covered by this
Work Letter: John Kelly, telephone (303)752-3500, facsimile (303)755-9721.
Landlord is entitled to rely on information and decisions of Tenant's
Representative, and the signature of Tenant's Representative on documents,
change orders, Work Cost Estimate and other instruments delivered in connection
with this Work Letter, shall be conclusive evidence of Tenant's approval.

All communications with respect to the matters covered by this Work Letter are
to be made to Landlord's Representative or Tenant's Representative, as the case
may be, in writing in compliance with the notice provisions of the Lease. Either
party may change its representative under this Work Letter at any time by
written notice to the other party in compliance with the notice provisions of
the Lease.

4.   TENANT IMPROVEMENT PLANS.

     (a) Preparation of Space Plans. Tenant and Landlord have approved
Intergroup, Inc. ("Space Planner") to prepare the architectural drawings for the
Premises. Tenant acknowledges that Landlord shall have no liability to assure
that the design of the Premises is satisfactory for Tenant and for Tenant's use.
Tenant agrees to cause the Space Planner to prepare the preliminary space plans
for the layout of Premises ("Space Plans") on or before the outside date for
preparation of the Space Plans set forth in the Work Schedule. The Space Plans
are to be sufficient to convey the architectural design of the Premises and
layout of the Tenant Improvements therein and are to be submitted to Landlord
upon completion for Landlord approval, which will not be unreasonably withheld.
If Landlord disapproves any aspect of the Space Plans, Landlord will advise
Tenant in writing of such disapproval and the reasons therefor in accordance
with the Work Schedule. Tenant will have until the outside date specified in the
Work Schedule to cause the Space Planner to redesign the Space Plans
incorporating the revisions required by Landlord and to obtain Landlord's final
approval of the Space Plans.

     (b) Preparation of Construction Documents. Based on the approved Space
Plans, Tenant will cause its Space Planner to prepare complete architectural
plans, drawings and specifications and complete engineered mechanical, plumbing,
structural (if required) and electrical working drawings for all of the Tenant
Improvements for the Premises (collectively, the "Construction Documents"). The
Tenant shall also cause the Space Planner to use building standard materials and
details for building spaces in accordance with the "Components of Standard
Tenant Finish for General Office Purposes" attached hereto as Exhibit J and
shall also use at Tenant's cost Landlord's engineers and consultants for
preparation of such working drawing. The Construction Documents are to be
completed on or before the outside date for completion of the Construction
Documents set forth in the Work Schedule. The Construction Documents will show:
(a) the subdivision (including partitions and walls), layout, lighting, finish
and decoration work (including carpeting and other floor coverings) for the
Premises, (b) all internal and external communications and utility facilities
which will require conduiting or other improvements from the base Building shell
work and/or within common areas; and (c) all other specifications for the Tenant
Improvements. The Construction Documents will be submitted to Landlord for
signature to confirm that they are consistent with the Space Plans. If Landlord
reasonably disapproves any aspect of the Construction Documents based on any

                                       C-2

<PAGE>

inconsistency with the Space Plans, which is reasonably acceptable to Landlord,
Landlord agrees to advise Tenant in writing of such disapproval and the reasons
therefor within the time frame set forth in the Work Schedule. Tenant will have
until the outside date specified in the Work Schedule to cause the Space Planner
to redesign the Construction Documents incorporating the revisions reasonably
requested by Landlord as to make the Construction Documents consistent with the
Space Plans and to obtain Landlord's final approval of the Space Plans.

     (c) Requirements of Tenant's Construction Documents. Tenant's Construction
Documents will include locations and complete dimensions, and the Tenant
Improvements, as shown on the Construction Documents, will: (i) be compatible
with the Building shell and with the design, construction and equipment of the
Building; (ii) comply with all applicable laws, ordinances, rules and
regulations of all governmental authorities having jurisdiction, and all
applicable insurance regulations; (iii) not require Building service beyond the
level normally provided to other tenants in the Building and will not overload
the Building floors; and (iv) be of a nature and quality consistent with the
overall objectives of Landlord for the Building, as determined by Landlord in
its reasonable but subjective discretion.

     (d) Submittal of Construction Documents. Once approved by Landlord and
Tenant, as provided in the Work Schedule, Tenant will cause the Space Planner to
submit the Construction Documents to the appropriate governmental agencies for
plan checking and the issuance of a building permit. Landlord will have the
right to review Space Planner's submittal package prior to delivery to such
governmental agencies. Space Planner, with the approval of Landlord and Tenant,
will make any changes to the Construction Documents which are requested by the
applicable governmental authorities to obtain the building permit. After
approval of the Construction Documents no further changes may be made without
the prior written approval of both Landlord and Tenant, and then only after
agreement by Tenant to pay any excess costs resulting from the design and/or
construction of such changes, if any. Tenant hereby acknowledges that any such
changes will be subject to the terms of Paragraph 8 below. Landlord shall have
no obligation to approve any further changes to the Construction Documents or
any amendment thereof or supplement thereto.

     (e) Work Cost Estimate and Statement. Prior to the commencement of
construction of any of the Tenant Improvements shown on the Construction
Documents, as provided in the Work Schedule, Landlord will cause the Contractor
to submit to Landlord and Tenant a written estimate of the cost to complete the
Tenant Improvement Work, which written estimate will be based on the
Construction Documents taking into account any modifications which may be
required to reflect changes in the Construction Documents required by the City,
County, Fire Department, Architectural Control Committee, and other governmental
approvals in which the Premises are located together with all space planning,
architectural engineering, supervision and other costs incurred in connection
therewith (the "Work Cost Estimate"). Tenant will either approve the Work Cost
Estimate or disapprove specific items and submit to Landlord revisions to the
Construction Documents to reflect deletions of and/or substitutions for such
disapproved items, and delays attributable to such changes shall be Tenant
Delays. Submission and approval of the Work Cost Estimate will proceed in
accordance with the Work Schedule. Upon Tenant's written approval of the Work
Cost Estimate (such approved Work Cost Estimate to be hereinafter known as the
"Work Cost Statement"), Landlord will have the right to cause the Contractor to

                                       C-3

<PAGE>

purchase materials and to commence the construction of the items included in the
Work Cost Statement pursuant to Paragraph 6 hereof. If the total costs reflected
in the Work Cost Statement exceed the Allowance as more specifically described
in Paragraph 5 below, Tenant agrees to pay such excess within fifteen (15) days
after billing therefor by Landlord without further notice, and Landlord's
billing will be within thirty (30) days of the date that said funds are due by
Landlord to its contractor or subcontractor. Throughout the course of
construction, any differences between the estimated Work Cost in the Work Cost
Statement and the actual Work Cost will be determined by Landlord and
appropriate adjustments and payments by Landlord or Tenant, as the case may be,
will be made within fifteen (15) days of billing, as set forth above. Delays in
completion of the Tenant Improvements shall be Tenant Delays, as set forth in
Paragraph 8 below.

5.   PAYMENT FOR THE TENANT IMPROVEMENTS.

     (a) Allowance. Landlord hereby grants to Tenant a tenant improvement
allowance of $22.16 per useable square foot of the Premises, plus at Tenant's
election, if the actual Work Cost exceeds the foregoing allowance, an additional
$4.00 per useable square foot, which amount if used by Tenant shall be added to
Base Rent and amortized from the earlier of January 1, 2000 or the Commencement
Date over the remainder of the Lease term at the rate of ten percent (10%) per
annum (such $22.16 per useable square foot allowance and $4.00 per useable
square foot allowance, if applicable, being collectively referred to as the
"Allowance"). The Allowance is to be used for all design, construction,

     (b) Excess Costs. The cost of each item referenced in Paragraph 5(a) above

Tenant agrees to deposit with Landlord such excess within fifteen (15) days
after invoice therefor and Landlord's billing will be within thirty (30) days of
the date that said funds are due by Landlord to its contractor or subcontractor.
In no event shall Tenant be entitled to any remaining balance of the Allowance.

     (d) Changes. If, after the Construction Documents have been prepared and
the Work Cost Statement has been established, Tenant requires any changes or
substitutions to the Construction Documents, any additional estimated costs
related thereto are to be paid by Tenant to Landlord prior to the commencement
of construction of the Tenant Improvements. Any changes to the Construction
Documents will be approved by Landlord and Tenant in the manner set forth in
Paragraph 4 above and will, if necessary, require the Work Cost Statement to be
revised and agreed upon between Landlord and Tenant in the manner set forth in
Subparagraph 4(e) above. Changes to the Construction Documents which delay
completion of the Tenant Improvements will constitute "Tenant Delays" as

billing will be within thirty (30) days of the date that said funds are due by
Landlord to its contractor or subcontractor.

available to Tenant as a credit against any obligations of Tenant under the
Lease.

6.   CONSTRUCTION OF TENANT IMPROVEMENTS. Until Tenant approves the Construction
Documents and Work Cost Statement, Landlord will be under no obligation to cause
the Contractor to commence the construction of any of the Tenant Improvements.
Following Tenant's approval of the Work Cost Statement described in Subparagraph
4(e) above and upon Tenant's payment of the total amount by which such Work Cost
Statement exceeds the Allowance, if any, Landlord will cause the Contractor to
commence and diligently proceed with the construction of the Tenant
Improvements, subject to Tenant Delays (as described in Paragraph 8 below) and
Force Majeure Delays (as described in Paragraph 9 below).

7.   COMMENCEMENT DATE AND SUBSTANTIAL COMPLETION.

     (a) Commencement Date. No Tenant Delay of any kind shall cause an extension
of the Commencement Date as set forth in Section 2.1 of the Lease.

     (b) Substantial Completion; Punch-List. The Tenant Improvements will be
deemed to be substantially completed ("Substantial Completion") when: (a)
Landlord is able to provide Tenant with reasonable access to the Premises; (b)
when the Space Planner certifies to Tenant and Landlord that the Contractor has
substantially performed all of the Tenant Improvement Work required to be
performed by Landlord under this Work Letter substantially in accordance with
the Construction Documents, other than minor "punch-list" type items and
adjustments which do not materially interfere with Tenant's access to or use of
the Premises (the "Punch List"); (c) Contractor has obtained a temporary
certificate of occupancy or other required equivalent approval from the local
governmental authority permitting occupancy of the Premises. Within five (5)
business days after receipt of such certificate from the Contractor, Tenant will
conduct a walk-through inspection of the Premises with Landlord, Tenant's
Representative and the Contractor, and the parties will jointly prepare a
written Punch List specifying those Punch List items which require completion,
which items Landlord will cause the Contractor to thereafter diligently
complete, subject to Force Majeure. Tenant may not take occupancy prior to
preparation of the Punch List. If Tenant takes occupancy prior to completion of
the Punch List, it shall take possession subject to all terms and conditions of
this Lease and in no event may Tenant interfere with or delay the completion of
the Punch List.

8.   TENANT DELAYS. For purposes of this Work Letter, "Tenant Delays" means any
delay in the completion of the Tenant Improvements resulting from any or all of
the following: (a) Tenant's failure to timely perform any of its obligations
pursuant to this Work Letter, including any failure to complete, on or before
the due date therefor, any action item which is Tenant's responsibility pursuant
to the Work Schedule delivered by Landlord to Tenant pursuant to this Work
Letter provided Landlord notifies Tenant in writing within a reasonable time
that Tenant's failure to act will delay the completion of the Tenant
Improvements; (b) Tenant's changes to Space Plans or Construction Documents
after Landlord's approval thereof; (c) in the delivery, installation or
completion of Tenant's requested materials, finishes, or installations; (d) any

                                       C-6

<PAGE>

delay of Tenant in making payment to Landlord for Tenant's share of the Work
Cost; or (e) any other act, delay or failure to act caused directly or
indirectly by Tenant, Tenant's employees, agents, architects, contractors,
independent contractors, consultants and/or any other person performing or
required to perform services on behalf of Tenant, including without limitation,
delay, action or inaction by Space Planner, it being acknowledged by Tenant that
Tenant has selected such party to provide services pursuant to this Work Letter.
These items will only amount to Tenant Delays if such events actually delay the
Commencement Date of this Lease. Landlord agrees to use reasonable efforts to
notify Tenant of Tenant Delays.

9.  FORCE MAJEURE DELAYS. For purposes of the Lease and this Work Letter, "Force
Majeure Delays" means any actual delay in the construction of the Tenant
Improvements resulting from events beyond the reasonable control of either
party, including but not limited to, delays caused or contributed to by
governmental or quasi-governmental entities, lenders, and acts of God.

10. TENANT APPROVALS. Anything submitted to Landlord by Tenant's Representative
shall be deemed to have the prior approval of Tenant. Furthermore, anything
submitted to Tenant's Representative for approval which is not disapproved
within five (5) business days of receipt of the submission shall be deemed
approved in all respects. The five (5) business day response period does not
extend the dates set forth in the Work Schedule for such approvals. All notices
given in connection with this Work Letter shall be in accordance with Section
26.1 of the Lease.

11. ADA. Landlord acknowledges and represents that the common areas of the
Building were constructed in accordance with Title III of the Americans with
Disabilities Act as in effect at the time of issuance of the building permit for
the Building. Improvements required for compliance with ADA for restrooms and
water fountains in the Premises will be part of the Tenant Improvements to be
constructed in accordance with this Work Letter.

12. HAZARDOUS MATERIALS. Landlord represents, to its current, actual knowledge,
that the Building was constructed in compliance with all applicable federal,
state and local ordinances relating to environmental protection and/or hazardous
materials.

    IN WITNESS WHEREOF, the undersigned Landlord and Tenant have caused this
Work Letter to be duly executed by their duly authorized representatives as of
the date of the Lease.
