Lease or to perform certain other obligations which are not within the control
of Sublessor. Therefore, Sublessee is entitled to receive only those utilities

building maintenance services including janitorial and customary interior and
exterior maintenance as a part of the Rent paid. Sublessee waives and release

<PAGE>   3
Sublessee shall perform all repairs and maintenance to the Subleased Premises
as required by Sublessor (as tenant) under the Prime Lease. If Sublessee does
not perform such obligations within ten (10) days after receipt of Sublessor's
notice, Sublessor may, but need not, perform such obligations and Sublessee
shall reimburse Sublessor for such cost on demand. Sublessor shall have no
obligation to maintain or repair the Subleased Premises or any fixture or
furnishing therein. Sublessee shall promptly notify Sublessor of any maintenance
or repairs needed in the Subleased Premises, regardless of which party has the
obligation for such maintenance or repair.

                                   ARTICLE IV
               USE: COMPLIANCE WITH LAWS AND RULES AND REGULATIONS

         SECTION 4.01. USE. Sublessee may use the Subleased Premises for general
office purposes only and in no event for any use prohibited or restricted by the
Prime Lease or by law. Sublessee shall not commit or permit to be committed on

condition of the Prime Lease.

         SECTION 4.02. COMPLIANCE WITH LAWS, AND RULES AND REGULATIONS.
Sublessee shall, at its sole cost and expense, from and after the Commencement
Date comply with, and cause the Subleased Premises to comply with, all laws,

Sublessee's use and occupancy thereof. Sublessee agrees that it shall comply
with all laws and with the rules and regulations stated in the Prime Lease
including all rules or regulations later promulgated by Prime Lessor.

                                    ARTICLE V
                            RENT AND ADDITIONAL RENT

         SECTION 5.01. BASE RENT. Sublessee shall pay to Sublessor, an annual
base rent at the rate of $13.90 per rentable square foot per annum in the
aggregate amount of $503,819.40 ("BASE RENT") payable in equal monthly
installments of $41,984.95 in advance on the first day of each month, commencing
on the Commencement Date, prorated for any portion of a month.

         SECTION 5.02 ADDITIONAL RENT. In addition to paying the Base Rent due
hereunder, Sublessee shall pay to Sublessor, as Additional Rent, its
proportionate share of any escalations for increases in Operating Expenses (as
such term is defined in Section 2.02 of the Prime Lease), when and as such
Operating Expenses are billed to Sublessor (as tenant) from Prime Lessor under
the Prime Lease, said amount is currently $6.21 per rentable square foot. In
addition, any and all other charges imposed on Sublessor (as tenant) under the
Prime Lease shall be borne by Sublessee on the same terms and conditions as
provided for in the Prime Lease and likewise shall be paid to Sublessor when and
as such charges are billed to Sublessor (as tenant) under the Prime Lease.
Sublessee shall make any and all such payments directly to Sublessor at the
address stated in Section 5.05 hereof or such other persons as the Sublessor may
from time to time direct. For purposes hereof, Sublessee's proportionate share
of Operating Expenses shall be determined by multiplying Operating Expenses by a
fraction, the numerator of which is the number of rentable square feet of
Subleased Premises and the denominator of which is the number of rentable square
feet of the Premises as follows: Sublessee's proportionate share is
approximately 34.26% (36,246rsf/105,790rsf=34.26%). In the event that the Prime
Lessor invoices the Sublessor on a monthly basis for the estimated Operating
Expenses, Sublessor shall then invoice Sublessee on a monthly basis for the
estimated Operating Expenses, in accordance with Section 2.02 of the Prime
Lease. Sublessee shall have fifteen (15) days to pay Sublessor after receipt of
the written invoice. Within six (6) months following the close of each calendar
year and following receipt of the documentation from the Prime Lessor, Sublessor
shall provide an accounting showing in reasonable detail all computation of the
operating expenses for that year.

         SECTION 5.03. COST OF ADDITIONAL SERVICES. Sublessee shall also be
responsible for paying directly to Sublessor (or to such other persons as
Sublessor shall from time to time direct) the cost of any additional services
provided to the

                                       3

<PAGE>   4
Subleased Premises or based on Sublessee's use and occupancy of the Subleased
Premises. Sublessee shall make payment of any and all such services within
thirty (30) days following Sublessee's receipt of Sublessor's request for
payment.

         SECTION 5.04. LATE CHARGE. If any installment of Base Rent is not paid
by the tenth (10th) day of the month during which such Base Rent is due, or if
any other amount (including Additional Rent) is not paid by the tenth (10th) day
following the date such amount is due, then in addition to such sum, Sublessee
shall pay (i) a late fee equal to ten percent (10%) of such sum until paid.

         SECTION 5.05. PAYMENT. Base Rent, Additional Rent, and all other sums
payable by Sublessee under this Sublease shall be paid to Sublessor without
notice or demand and without any deduction, abatement or set-off in legal United
States tender at the following address:

                           MCI SYSTEMHOUSE CORP.

or to such other party or address as Sublessor may designate by written notice
to Sublessee. Invoices for rent due shall be rendered only for the first month
of the Sublease Term and not for recurring months. Sublessor's acceptance of
late rent payments shall not excuse such delay nor any future delays in payment
nor constitute a waiver of rights, notwithstanding any endorsement or
restriction that Sublessee may include with such payment.

         SECTION 5.06. TAX ON SUBLESSEE'S PERSONAL PROPERTY. Sublessee shall
also be responsible for paying any tax due on Sublessee's equipment or personal
property, if such tax is billed by the taxing authority.

                                   ARTICLE VI
                                SECURITY DEPOSIT

         Subtenant has deposited the sum of One Hundred Twenty Thousand and
No/l00 Dollars ($120,000.00) in a form of a Letter of Credit for the full term
of the Sublease, with Sublandlord as security for Subtenant's payment of rent
and performance of its other obligations under this Sublease. If Subtenant
defaults in its payment of rent or performance of its other obligations,
Sublandlord may draw down all or a part of the security deposit for the payment
of rent or any other sums in default, or for the payment of any other sums which
Sublandlord may spend by reason of Subtenant's default, or for the payment to
Sublandlord of any other loss or damage which Sublandlord may suffer by reason
of Subtenant's default.

         If Sublandlord uses any portion of the Letter of Credit, Subtenant will
restore the Letter of Credit to its original amount within five (5) days after
written demand from Sublandlord. The Security Deposit shall not be a limitation
on Sublandlord's damages or other rights under this Sublease, or a payment of
liquidated damages, or an advance payment of the rent. If Subtenant pays the
rent and performs all of its other obligations under this Sublease, Sublandlord
shall return the Letter of Credit to Subtenant within fifteen (15) days after
the end of the Sublease Term.

                                   ARTICLE VII

                                  ARTICLE VIII
                          INCORPORATION OF PRIME LEASE

         SECTION 8.01. INCORPORATION OF SUBLEASE WITH PRIME LEASE. So long as
the provisions of the Prime Lease pertaining to the Subleased Premises do not
conflict with or are applicable to the specific provisions of this Sublease (or
are not excluded below), such provisions are incorporated into and made a part
of this Sublease. Subject to the preceding sentence, Sublessee shall be bound by
all the provisions of the Prime Lease which pertain to the Subleased Premises
and shall perform all of the obligations and responsibilities that Sublessor is
obligated to perform (as tenant) pursuant to the Prime Lease related to the
Subleased Premises.

         Therefore, for purposes of this Sublease: (i) references in the Prime
Lease to "Landlord" shall mean the Sublessor; (ii) references in the Prime Lease
to "Tenant" shall mean the Sublessee; (iii) references in the Prime Lease to
"Leased Premises" or similar words shall mean the Subleased Premises; (iv)
references in the Prime Lease to "Term" shall mean the Sublease Term; and (v)
references in the Prime Lease to "use and occupancy" shall refer to Sublessee's
use and occupancy of the Subleased Premises. All terms not specifically defined
herein shall have the same meanings designated in the Prime Lease provided that
such words are not in conflict with the provisions of this Sublease.

         The Prime Lease contains certain provisions that are not applicable to
this Sublease. The parties agree that the following sections of the Prime Lease
are not incorporated into this Sublease: (i) any provisions that are in direct

                                        5

<PAGE>   6

conflict with the Sublease; (ii) any provisions relating to Prime Lessor's or
Sublessor's obligations regarding the initial construction of the Premises, the
intent of this provision being to acknowledge that construction of the Premises
covered by the Prime Lease are complete. Notwithstanding and in addition to the
preceding sentence, and not by way of limitation, the following provisions of
the Prime Lease shall not apply to Sublessee under this Sublease: Sections 15.4
and 16.14, Exhibits E and G, and Rider to Lease, Paragraphs 14, 18 and 19.

         SECTION 8.02. PRIVITY. Except as specifically provided herein, nothing
contained in this Sublease shall be construed to create privity of estate or
privity of contract between Sublessee and Prime Lessor.

         SECTION 8.03. BREACH OF PRIME LEASE: INDEMNIFICATION. Sublessee shall
not do or permit to be done any act or thing which will constitute a breach or
violation of any of the provisions of the Prime Lease or of any law, ordinance,
rule or regulation of any governmental body applicable to the Subleased Premises
and/or Sublessee's use and occupancy thereof. Sublessee will indemnify and hold
Sublessor harmless from and against all losses, costs, damages, expenses
(including reasonable attorneys' fees), penalties and liabilities which
Sublessor may incur or pay out by reason of any such violation or breach or any
injuries to persons or property occurring in, on or about the Subleased
Premises, or by reason of any breach, default or act of negligence hereunder by
Sublessee, its officers, employees or agents, or by reason of any work done on,
in or to the Subleased Premises by, for or on behalf of Sublessee. Likewise,
Sublessor shall not do or permit to be done any act or thing which will
constitute a breach or violation of any of the provisions of the Prime Lease.

         SECTION 8.04. RIGHTS/OBLIGATIONS. Notwithstanding any provision to the
contrary in this Sublease, Sublessee shall in no case have any rights with
respect to the Subleased Premises, unless and except as specifically provided in
this Sublease, and Sublessee hereby agrees to assume all of Sublessor's
obligations under the Prime Lease, except as may be specifically provided herein
to the contrary. For example, whenever a provision of the Prime Lease which is
incorporated herein by reference requires Sublessor (as tenant) under the Prime
Lease, to perform an act or conduct a repair, such provision shall obligate
Sublessee to perform such act.

         SECTION 8.05. TERMINATION OR MODIFICATION OF PRIME LEASE. If the term
of the Prime Lease is terminated prior to the expiration date of this Sublease,
this Sublease shall thereupon be terminated and Sublessor shall not be liable to
Sublessee by reason thereof unless such termination shall be due to the breach
or default of Sublessor under the terms of the Prime Lease. Sublessor hereby
agrees that it will not enter into any agreement with the Prime Lessor with
respect to the termination, surrender and acceptance of the Prime Lease, as
related to the Subleased Premises, without the prior written consent of the
Sublessee, which consent shall not be unreasonably withheld or delayed.

         SECTION 8.06. SUBORDINATION OF SUBLEASE TO THE PRIME LEASE. This
Sublease is subject and subordinate to the Prime Lease and to all mortgages,
ground leases, security agreements or other encumbrances to which the Prime
Lease is subject and subordinate. Sublessee shall not by any act or failure to
act cause any default under the Prime Lease nor do anything which is prohibited
under the Prime Lease.

         SECTION 8.07. DEFAULT BY PRIME LESSOR. If Prime Lessor shall default
under any of the provisions of the Prime Lease, such default shall not
constitute a default by Sublessor under this Sublease and Sublessor shall not be
obligated to cure Prime Lessor's default. Sublessor shall have no obligation to
enforce any right or remedy under the Prime Lease for Sublessee's benefit and
Sublessor shall have no liability to Sublessee for any default under the Prime
Lease by Prime Lessor.

                                   ARTICLE IX
                            ASSIGNMENT AND SUBLETTING

         SECTION 9.01. NO ASSIGNMENT AND SUBLETTING WITHOUT CONSENT. Sublessee
shall not assign or sublet this Sublease or any part of the Subleased Premises
or any right or privilege

                                       6

appurtenant thereto, and shall not suffer or permit any other person (excepting
agents, servants or associates of Sublessee) to occupy or use the Subleased
Premises or any portion thereof, without the prior written consent of Sublessor.
Further, any assignment or subletting by Sublessee without such prior written
consent of Sublessor shall be void and shall, at the option of Sublessor,
terminate this Sublease.

                                    ARTICLE X
                                    INSURANCE

         SECTION 10.01. SUBLESSEE'S INSURANCE. Sublessee shall maintain with
respect to the Subleased Premises comprehensive public liability and property
damage insurance in minimum limits as stated in Article 13 of the Prime Lease,
insuring Sublessor, Prime Lessor and Sublessee against bodily injury or death to
persons, and against damage to property as herein provided. Sublessee shall
deliver a certificate of such insurance to Sublessor and to Prime Lessor within
fifteen (15) days after the date hereof and Sublessor and Prime Lessor shall be
named as an additional insured on such policy. Such insurance policy shall be in
form reasonably satisfactory to Sublessor and to Prime Lessor, and shall be
placed with a company qualified to do business in the State where the Subleased
Premises are located. Such policy shall provide that it cannot be cancelled
without at least thirty (30) days prior written notice to Sublessor.

                                   ARTICLE XI
                                  MISCELLANEOUS

         SECTION 11.01. BROKERS. Sublessor and Sublessee acknowledge that Olive
Real Estate Group, Inc. has acted as broker with regard to the Subleased
Premises and that Sublessor shall be solely responsible for, and shall pay to
said broker, a real estate commission in accordance with the terms of a separate
agreement. Sublessor agrees to indemnify, defend and hold Sublessee harmless
from any claim for such commission, and furthermore, Sublessor agrees that
should any other broker make a claim for a commission based upon the actions of

1.   INTEREST RATE AND PAYMENT - The interest rate for your account will be paid
     until the maturity date of your certificate. Interest begins to accrue on
     the business day you deposit noncash items (for example, checks). Interest
     will not be compounded. Interest will be credited according to your
     instructions at the time your account is opened. The interest payment may
     be credited to your certificate at maturity, credited to another account at
     the Bank, or paid by cashier's check on either a monthly, quarterly,
     semi-annual or annual basis or at maturity of the certificate. However, if
     the certificate is less than 31 days, interest will only be credited at
     maturity. We use the daily balance method to calculate the interest on your
     account. This method applies a daily periodic rate to the principal rate in
     the account each day.

2.   ADDITIONAL DEPOSITS - After the account is opened, deposits will only be
     accepted on the maturity date or any date within the grace period.

3.   RENEWAL - This account will automatically renew at maturity for a like

     of two (2) business days on a maturity of a 7-31 day term account. You have
     a grace period of ten (10) business days on a maturity of a 32 or more day
     term account. The Bank reserves the right to terminate this term deposit
     during any renewal period upon 10 days written notice to depositor. If you
     withdraw your funds during the grace period, the term deposit will cease
     earning interest as of the maturity date.

4.   PENALTY FOR EARLY WITHDRAWAL - Partial withdrawals will not be permitted.
     If we permit a withdrawal before the maturity date, a penalty as shown
     below will be imposed.
     a.   Deposits with an original maturity of 31 days or less will forfeit all
          interest earned from the date of deposit. There is a minimum penalty
          of seven (7) days simple interest.
     b.   Deposits with an original maturity of 32 days to one year will forfeit
          an amount equal to 31 days simple interest at the interest rate paid

          the deposit.
     c.   Deposits with an original maturity of more than one year will forfeit
          an amount equal to 90 days simple interest at the interest rate being

                          AMENDMENT OF LEASE AGREEMENT

This Amendment of Lease is made this 9th day of December, 1996 by and between
One Mall, LLC, a Maryland Limited Liability Company (the "Landlord"), and SHL
ACT Systemhouse Corp., successor in interest to SHL Kee Systems Inc. (the
"Tenant").

                                    RECITALS

     1.   Landlord is the owner of the One Mall North Building (the "Building"),
          an office building located at 10025 Governor Warfield Parkway,
          Columbia, Maryland 21044.

     2.   The Landlord and the successor to the Tenant have entered into an
          agreement of Lease, dated July 31, 1995, whereby, among other things,
          the Landlord has leased unto the Tenant (the "Lease") that certain
          portion of the fourth floor of the Building containing approximately
          13,029 rentable square feet of space (the "Fourth Floor Space"), and
          that portion of the first floor at the Building (the "First Floor
          Space") containing approximately 3,750 rentable square feet.

     3.   The Lease has been assigned to the Tenant with Landlord's consent.

     4.   The Lease, pursuant to its terms, creates the obligation on the
          part of the Tenant to expand into the Must Take Space on the fourth
          floor of the Building as shown on Exhibit A of the Lease (the "Must
          Take Space") on or before September 1, 1996. Tenant actually expanded
          into the Must Take Space as of April 15, 1996 and has been paying rent
          pursuant to the terms set forth herein since that date.

     5.   Tenant desires to future expand on the first floor of the Building,
          in accordance with the terms and conditions and plan set forth below
          (the "First Floor Expansion Space").

NOW, THEREFORE, in consideration of the mutual promises of the parties hereto,
the promises, and other valuable consideration, the receipt and sufficiency
of which are hereby acknowledged, the parties hereto do hereby agree as follows:

     1.   Lease: Except as provided herein, all the terms and conditions under
          the Lease shall remain in full force and effect.

     2.   Must Take Space: As of April 15, 1996 the Fourth Floor Space shall be
          increased by the Must Take Space, as shown on Exhibit A hereto, which
          Must Take Space contains, the agreed upon equivalent of 775 rentable
          square feet (the Must Take Space and the Fourth Floor Space shall
          hereinafter collectively be the "Expanded Fourth Floor Space").

<PAGE>   18

3.   Rental:

     a)   From April 15, 1996 and throughout the Lease Term, the basic annual
          rent for the Must Take Space shall be paid at the same rental rates
          per rentable square foot and in the same manner as set forth in
          Section 5 of the Lease.

     b)   The rental to be paid by Tenant for the First Floor Expansion Space
          shall be at the rental rates set forth in the Lease plus ($2.00) per
          square foot and shall commence November 1, 1996.

     c)   The percentage of the Building that is occupied by the Tenant shall be
          increased by 3% for purposes of computing Tenant's allocable
          percentage of any Operating Expense and Real Estate Tax increases.

4.   Tenant Improvements: Tenant acknowledges and agrees that Landlord has
     delivered the Must Take Space as required under the Lease. The build out
     specifications for the First Floor Expansion Space is set forth on Exhibit
     B hereto and dated "Revision 20-08-96" which Landlord agrees to construct
     on a turn key basis. If Tenant makes any changes to the Exhibit, Tenant
     agrees to promptly reimburse Landlord for any costs Landlord incurs beyond
     the cost to construct the space.

5.   First Floor Expansion Space: The First Floor Expansion Space is shown on
     Exhibit B attached hereto and incorporated by reference herein and consists
     of 2,088 rentable square feet.

6.   Term: The initial Term for the Must Take Space and the First Floor
     Expansion Space shall be coterminous with the Term as set forth in the
     Lease, it being the express intention of the parties that the Term for the
     Must Take Space shall commence on April 15, 1996 and that the term for the
     First Floor Expansion Space shall commence on November 1, 1996, and shall
     expire on August 31, 2000. With respect to the First Floor Expansion Space
     only, Landlord agrees that Tenant provided Tenant is not in default
     hereunder, shall have the right to terminate the Lease as of December 31,
     1997, (the "Termination Date"), by doing all of the following:

                             ARTICLE 2.00 RENT

     2.01 BASE RENT. Lessee agrees to pay monthly as Base Rent during the term
of this Lease the sum of money set forth below, which amount shall be payable at
the address set forth in Section 16.07.

<PAGE>   24
                              Base Rental Rate/                  Monthly
    Months                       SF/YR/NNN                     Base Rent
     36                            $13.90                     $41,984.95

Monthly installment shall be due and payable on or before the first day of each
calendar month succeeding the Commencement Date during the term of this Lease
provided, if the Commencement Date should be a date other than the first day of
a calendar month, the monthly Base Rent set forth above shall be prorated based
on a thirty day month to the end of that calendar month, and all succeeding
installments of rent shall be payable on or before the first day of each
succeeding calendar month during the term of this Lease. Lessee shall pay as
additional rent, all other sums due under this Lease.

     2.02 OPERATING EXPENSES. Lessee agrees to pay as additional rent Lessee's
pro rata share of Operating Expenses as defined in Section 2.03 below. For
purposes of this Lease, Lessee's pro rata share shall be determined by dividing
36,246 (the approximate square footage for the Leased Premises) by 105,790 (the
approximate square footage of the building), multiplying the resulting quotient
by 100, and rounding to the second decimal place (approximately 34.26%).
Tenant's pro rata share shall be adjusted accordingly if the square footage of
the Leased Premises is increased pursuant to the terms of this Lease. Lessor may
invoice Lessee monthly for Lessee's pro rata share of the estimated Operating
Expenses for each calendar year, which amount shall be adjusted each year based
upon the anticipated Operating Expenses. Within six months following the close
of each calendar year, Lessor shall provide Lessee an accounting showing in
reasonable detail all computations of additional rent due under this section. In
the event the accounting shows that the total of the monthly payments made by
Lessee exceeds the amount of additional rent due by Lessee under this section,
the accounting shall be accompanied by a refund. In the event the accounting
shows that the total of the monthly payments made by Lessee is less than the
amount of additional rent due by Lessee under this section, the accounting shall
be accompanied by an invoice for the additional rent. Notwithstanding any other
provisions in this Lease, during the year in which the Lease terminates, Lessor,
prior to the termination date, shall have the option to invoice Lessee for
Lessee's pro rata share of the Operating Expenses based upon the previous year's
Operating Expenses. If this Lease shall terminate on a day other than the last
day of a calendar year, the amount of any additional rent payable by Lessee
applicable to the year in which such termination shall occur shall be prorated
on the ratio that the number of days from the commencement of the calendar year
to and including the termination date bears to 365. Lessee shall have the right,
at its own expense, within ninety (90) days of receipt of any invoice, to audit
Lessor's books relevant to the additional rent payable under such invoice. After
such ninety (90) day period, Lessee's right to audit with respect to such
invoice is waived. Lessee agrees to pay any additional rent due under this
section within thirty (30) days following receipt of the invoice or accounting
showing additional rent due. [See Rider, Paragraph 1.]

     2.03 DEFINITION OF OPERATING EXPENSES. The term "Operating Expenses"
includes all expenses incurred by Lessor with respect to the maintenance and
operation of the parking areas and the Building of which the Leased Premises are
a part, including, but not limited to, the following: maintenance, repair and
replacement costs; electricity, fuel, water, sewer, gas and other utility
charges; security, window washing and janitorial services; trash and snow
removal; landscaping and pest control; management fees, wages and benefits
payable to employees of Lessor whose duties are directly connected with the
operation and maintenance of the building; all services, supplies, repairs,
landscaping replacements or other expenses for maintaining and operating the
building or project including parking and common areas; the cost, including
interest, amortized over its useful life, of any capital improvement made to the
building which is required under any governmental law or regulation that was not
applicable to the building at the time it was constructed; the cost, including
interest, amortized over its useful life, of installation of any device or other
equipment which improves any system within the Leased Premises or the building;
all other expenses which would generally be regarded as operating, ownership and
maintenance expenses which would reasonably be amortized over a period in
accordance with

                                        2
<PAGE>   25
generally accepted Internal Revenue Service amortization schedules; all real
property taxes and installments of special assessments, including assessments by
means of deed restrictions and/or owners' associations which accrue against the
building of which the Leased Premises are a part during the term of this Lease;
and all insurance premiums Lessor is required to pay or deems necessary to pay,
including public liability insurance, with respect to the building. The term

work occasioned by fire, wind, the elements or other casualty to the extent of
insurance proceeds; income and franchise taxes of Lessor; expenses incurred in
leasing to or procuring of lessees, leasing commissions, advertising expenses
and expenses for the renovating of space for new lessees; interest or principal
payments on any mortgage or other indebtedness of Lessor; compensation paid to
any employee of Lessor above the grade of property manager; any depreciation
allowance or expense; Operating Expenses which are the direct responsibility of

directly billed to such lessee; any income, estate, inheritance, transfer tax,
excess profit or franchise tax on Lessor's business; all costs, including legal
fees, relating to activities for the solicitation and execution of leases of
space in the building; any delinquent interest or penalties due or charged for
late payment of taxes; or any legal fees incurred by Lessor in enforcing its
rights under other leases for premises in the building. [See Rider, Paragraph
2.]

     2.04 LATE PAYMENT CHARGE. Other remedies for nonpayment of rent
notwithstanding, if the monthly rental payment is not received by Lessor on or
before the tenth day; of the month for which the rent is due, or if any other
payment due Lessor by Lessee is not received by Lessor on or before the tenth
day of the month next following the month in which Lessee was invoiced, a late
payment charge of five percent (5%) applied to such past due amount shall become
due and payable in addition to such amounts owed under this Lease.

     2.05 INCREASE IN INSURANCE PREMIUM. If an increase in any insurance
premiums paid by Lessor for the building is caused by Lessee's use of the
Leased Premises in a manner other than as set forth in Section 1.06, or if
Lessee vacates the Leased Premises and causes an increase in such premiums, then
Lessee shall pay as additional rent the amount of such increase to Lessor,
within thirty (30) days after receipt of invoice with supporting documentation
attached.

     2.06 SECURITY DEPOSIT. Intentionally Deleted.

this Lease shall be applicable during that period, except that Lessee shall pay
Lessor as Base Rental for the period of such holdover an amount equal to one and
one-half (1.5) times the Base Rent which would have been payable by Lessee had
the holdover period been a part of the original term of this Lease. Lessee
agrees to vacate and deliver the Leased Premises to Lessor upon Lessee's receipt
of written notice from Lessor to vacate. The rental payable during the holdover
period shall be payable to Lessor on demand. No holding over by Lessee, whether
with or without the consent of Lessor, shall operate to extend the term of this
Lease.

                         ARTICLE 3.00 OCCUPANCY AND USE

     3.01 USE. Lessee warrants and represents to Lessor that the Leased Premises
shall be used and occupied only for the purpose as set forth in Section 1.06.
Lessee shall occupy the Leased Premises, conduct its business and control its
agents, employees, invitees and visitors in such a manner as is lawful,
reputable and will not create a nuisance. Lessee shall not permit any operation
which emits any odor or matter which intrudes into other portions of the
building, use any apparatus or machine which makes undue noise or causes
vibration in any portion of the building or otherwise interfere with, annoy or
disturb any other lessee in its normal business operations or Lessor in its
management of the building. Lessee shall neither permit any waste on the Leased
Premises nor allow the Leased Premises to be used in any

                                       3
<PAGE>   26
way which would, in the opinion of Lessor, be extra hazardous on account of fire
or which would in any way increase or render void the fire insurance on the
building.

     3.02 SIGNS. No sign of any type or description shall be erected, placed or
painted in or about the Leased Premises or project except those signs submitted
to Lessor in writing and approved by Lessor in writing, and which signs are in

     3.03 COMPLIANCE WITH LAWS, RULES AND REGULATIONS. Lessee, at Lessee's sole
cost and expense, shall comply with all laws, ordinances, orders, rules and
regulations of state, federal, municipal or other agencies or bodies having
jurisdiction over the use, condition or occupancy of the Leased Premises. Lessee
will comply with the rules and regulations of the building adopted by Lessor
which are set forth on Exhibit G attached to this Lease. Lessor shall have the
right at all times to change and amend the rules and regulations in any
reasonable manner as may be deemed advisable for the safety, care, cleanliness,
preservation of good order and operation or use of the building or the Leased
Premises. All changes and amendments to the rules and regulations of the
building will be sent by Lessor to Lessee in writing and shall thereafter be
carried out and observed by Lessee. [See Rider, Paragraph 3.]

     3.04 WARRANTY OF POSSESSION. Lessor warrants that it has the right and
authority to execute this Lease, and Lessee, upon payment of the required rents
and subject to the terms, conditions, covenants and agreements contained in this
Lease, shall have possession of the Leased Premises during the full term of this
Lease as well as any extension or renewal thereof. Lessor shall not be
responsible for the acts or omissions of any other lessee or third party that
may interfere with Lessee's use and enjoyment of the Leased Premises.

     3.05 INSPECTION. Lessor or its authorized agents shall at any and all
reasonable times have the right to enter the Leased Premises to inspect the
same, to supply janitorial service or any other service to be provided by
Lessor, to show the Leased Premises to prospective purchasers and lenders of the
Building at any time upon reasonable prior verbal notice or to prospective
lessees during the last twelve (12) months of the Lease Term or if the Lessee is
in default then Lessor may show the Premises at any time, and to alter, improve
or repair the Leased Premises or any other portion of the building. Lessee
hereby waives any claim for damages for injury or inconvenience to or
interference with Lessee's business, any loss of occupancy or use of the Leased
Premises, and any other loss occasioned thereby (however, Lessee shall have the
right to have an employee or other agent present during any entry to show the
Premises or perform scheduled maintenance and shall in fact supply such escort
upon reasonable prior verbal request of Lessor). Lessor shall at all times have
and retain a key with which to unlock all of the doors in, upon and about the
Leased Premises except for portions of the Leased Premises that are on a
separate security system, which shall be accessible at any time upon prior
verbal request of Lessor, subject to Lessee's right to have an escort present.
Lessee shall not change Lessor's lock system or in any other manner prohibit
Lessor from entering the Leased Premises; however, Lessee may install, at its
expense, a "card key" or other similar security system provided Lessor is also
provided a "key" to the system. Lessor shall have the right to use any and all
means which Lessor may deem proper to open any door in an emergency without
liability therefor.

Lessee during the term of this Lease. Lessee shall pay all telephone charges.

regulations, such service on Saturday afternoons, Sundays, evenings and holidays
to be furnished only upon the request of Lessee, who shall bear the entire
cost). Lessor shall also provide routine maintenance, painting and electric
lighting service for all public areas and special service areas of the building
in

                                       4

<PAGE>   27
the manner and to the extent deemed by Lessor to be standard. Lessor may, in
its sole discretion, provide additional services not enumerated herein. Failure
by Lessor to any extent to provide these defined services or any other services
not enumerated, or any cessation thereof, shall not render Lessor liable in any
respect for damages to either person or property, be construed as an eviction of
Lessee, work an abatement of rent or relieve Lessee from fulfillment of any
covenant in this Lease. Should any of the equipment or machinery break down, or
for any cause cease to function properly, Lessor shall use reasonable diligence
to repair the same promptly, but Lessee shall have no claim for rebate of rent
on account of any interruption in service occasioned from the repairs. Lessor
reserves the right from time to time to make changes in the utilities and
services provided by Lessor to the building. [See Rider, Paragraph 4.]

     4.02 THEFT OR BURGLARY. Lessor shall not be liable to Lessee for losses to
lessee's property or personal injury caused by criminal acts or entry by
unauthorized persons into the Leased Premises or the building.

     4.03 JANITORIAL SERVICE. Lessor shall furnish janitorial services to the
Leased Premises and public areas of the building five times per week during the
term of this Lease, excluding holidays. Lessor shall not provide janitorial
service to kitchens.

     4.04 EXCESSIVE UTILITY CONSUMPTION. Lessee shall pay all utility costs
occasioned by electrodata processing machines, telephone equipment, computers
and other equipment of high electrical consumption, including without
limitation, the cost of installing, servicing and maintaining any special or
additional inside or outside wiring or lines, meters or submeters, transformers,
poles, air conditioning costs, or the cost of any other equipment necessary to
increase the amount or type of electricity or power available to the Leased
Premises. Lessor may at Lessee's expense submeter the Leased Premises and Lessee
shall pay for such utility costs used therein.

     4.05 WINDOW COVERINGS. Lessor shall furnish and install window coverings on
all exterior windows to maintain a uniform exterior appearance. Lessee shall not
remove or replace these window coverings or install any other window covering
which would affect the exterior appearance of the building. Lessee may install
lined or unlined over draperies on the interior sides of the Lessor furnished
window coverings for interior appearance or to reduce light transmission,
provided such over draperies do not affect the exterior appearance of the
building or affect the operation of the building's heating, ventilating and air
conditioning systems.

     4.06 CHARGE FOR SERVICE. Unless otherwise excluded in Section 2.02 hereof,
all costs of Lessor for providing the services set forth in Article 4.00 (except
those charges paid by Lessee pursuant to Section 4.04) shall be subject to the
additional rent provisions in Section 2.02.

                      ARTICLE 5.00 REPAIRS AND MAINTENANCE

     5.01 LESSOR REPAIRS. Unless otherwise excluded in Section 2.02 hereof,
Lessor shall not be required to make any improvements, replacements or repairs
of any kind or character to the Leased Premises or the project during the term
of this Lease except as are set forth in this section. Lessor shall maintain
only the roof, foundation, parking and common areas, the structural soundness of
the exterior walls, doors, corridors, windows and other standard structures or
standard equipment serving the Leased Premises, expressly excluding equipment
installed by or for the Lessee. Lessor's cost of maintaining and repairing the
items set forth in this section are subject to the additional rent provisions in
Section 2.02. Lessor shall not be liable to Lessee, except as expressly provided
in this Lease, for any damage or inconvenience, and Lessee shall not be entitled
to any abatement or reduction of rent, except as stated in the Lease, by reason
of any repairs, alterations or additions made by Lessor under this Lease.

     5.02 LESSEE REPAIRS. Lessee shall, at its own cost and expense, repair or
replace any damage or injury to all or any part of the Leased Premises caused by
any act or omission of Lessee or Lessee's agents, employees, invitees, licensees
or

                                       5
<PAGE>   28
visitors; provided, however, if Lessee fails to make the repairs or replacements
promptly, Lessor may, at its option, make the repairs or replacements, and the
costs of such repairs or replacements shall be charged to Lessee as additional
rent and shall become payable by Lessee with the payment of the rent next due
hereunder.

     5.03 REQUEST FOR REPAIRS. All requests for repairs or maintenance that are
the responsibility of Lessor pursuant to any provision of this Lease must be
made in writing to Lessor at the address in Section 1.05.

                    ARTICLE 6.00 ALTERATIONS AND IMPROVEMENTS

     6.01 LESSOR IMPROVEMENTS. If construction to the Leased Premises is to be
performed by Lessor prior to or during Lessee's occupancy, Lessor will complete
the construction of the improvements to the Leased Premises in accordance with
Exhibit C.

     6.02 LESSEE IMPROVEMENTS. Lessee shall not make or allow to be made any
alterations or physical additions in or to the Leased Premises without first
obtaining the written consent of Lessor, the consent for which may in the
reasonable discretion of Lessor be denied. Any alterations, physical additions
or improvements to the Leased Premises made by Lessee shall at once become the
property of Lessor and shall be surrendered to Lessor upon the termination of
this Lease; provided, however, Lessor, at its option, may require Lessee to
remove any physical additions and/or repair any alterations in order to restore
the Leased Premises to the condition existing at the time Lessee took
possession, all costs of removal and/or alterations to be borne by Lessee. This
clause shall not apply to moveable equipment or furniture owned by Lessee, which
may be removed by Lessee at the end of the term of this Lease if Lessee is not
then in default and if such equipment and furniture are not then subject to any
other rights, liens and interests of Lessor. [See Rider, Paragraph 5.]

     6.03 MECHANICS LIEN. Lessee will not permit any mechanic's or materialman's
lien(s) or other lien to be placed upon the Leased Premises or the building and
nothing in this Lease shall be deemed or construed in any way as constituting
the consent or request of Lessor, express or implied, by inference or otherwise,
to any person for the performance of any labor or the furnishing of any
materials to the Leased Premises, or any part thereof, nor as giving Lessee any
right, power, or authority to contract for or permit the rendering of any
services or the furnishing of any materials that would give rise to any
mechanic's, materialman's or other lien against the Leased Premises. In the
event any such lien is attached to the Leased Premises, then, in addition to any
other right or remedy of Lessor, Lessor may, but shall not be obligated to,
obtain the release of or otherwise discharge the same. Any amount paid by Lessor
for any of the aforesaid purposes shall be paid by Lessee to Lessor on demand as
additional rent. [See Rider, Paragraph 6.]

                              ARTICLE 7.00 CASUALTY

     7.01 SUBSTANTIAL DESTRUCTION. If the Leased Premises should be totally
destroyed by fire or other casualty, or if the Leased Premises should be damaged
so that rebuilding cannot reasonably be completed within ninety (90) working
days after the date of written notification by Lessee to Lessor of the
destruction, this Lease shall at Lessor's option terminate and the rent shall be
abated for the unexpired portion of the Lease, effective as of the date of the
written notification. Notwithstanding the foregoing, if the casualty occurs
during the last year of the Lease Term, Lessee, at its option, may terminate
this Lease upon thirty (30) days written notice to Lessor.

     7.02 PARTIAL DESTRUCTION. If the Leased Premises should be partially
damaged by fire or other casualty, and rebuilding or repairs can reasonably be
completed within ninety working days from the date of written notification by
Lessee to Lessor of the destruction, or Lessor does not elect to terminate this
Lease then Lessor shall, to the extent of insurance proceeds received by Lessor,
proceed with reasonable diligence to rebuild or repair the building or other
improvements to substantially the same condition in which they existed prior to
the damage. If the Leased Premises are to be rebuilt or repaired and are
untenantable in whole or in part following the damage, and

                                       6
<PAGE>   29
the damage or destruction was not caused or contributed to by act or negligence
of Lessee, its agents, employees, invitees or those for whom Lessee is
responsible, the rent payable under this Lease during the period for which the
Leased Premises are untenantable shall be equitably abated to such an extent as
may be fair and reasonable under the circumstances based upon the area of the
Leased Premises which are untenantable.

     7.03 HOLD HARMLESS. Lessor shall not be liable to Lessee's employees,
agents, invitees, licensees or visitors, or to any other person, for an injury
to person or damage to property on or about the Leased Premises caused by an act
or omission of Lessee, its agents, servants or employees, or of any other person
entering upon the Leased Premises under express or implied invitation by
Lessee, or caused by the improvements located on the Leased Premises becoming
out of repair, to the extent the improvements are not attributed to Lessor's
maintenance obligations as set forth in Section 5, the failure or cessation of
any service provided by Lessor (including security service and devices), or
caused by leakage of gas, oil, water or steam or by electricity emanating from
the Leased Premises. Lessee agrees to indemnify and hold harmless Lessor of and
from any loss, attorney's fees, expenses or claims arising out of any such
damage or injury.

                            ARTICLE 8.00 CONDEMNATION

     8.01 SUBSTANTIAL TAKING. If all or a substantial part of the Leased
Premises are taken for any public or quasi-public use under any governmental
law, ordinance or regulation, or by right of eminent domain or by purchase in
lieu thereof, and the taking would prevent or materially interfere with the use
of the Leased Premises for the purpose for which it is then being used (as
reasonably determined by Tenant to the extent that the actual square footage of
the Leased Premises is rendered untenantable), this Lease shall terminate and
the rent shall be abated during the unexpired portion of this Lease effective on
the date physical possession is taken by the condemning authority. With respect
to a partial taking of any portion of the Building or Building Complex other
than Suite 200, the election to terminate this Lease shall be in Lessor's
discretion. Lessee shall have no claim to the condemnation award or proceeds in
lieu thereof. Lessee may, in a separate legal action, make any separate claims
against the condemning authority permitted by Colorado law for trade fixtures
and moving expenses, but in no event shall any award to Lessee reduce the award
to Lessor.

     8.02 PARTIAL TAKING. If a portion of the Leased Premises shall be taken for
any public or quasi-public use under any governmental law, ordinance or
regulation, or by right of eminent domain or by purchase in lieu thereof, and
this Lease is not terminated as provided in Section 8.01 above, Lessor shall at
Lessor's sole risk and expense, restore and reconstruct the building and other
improvements on the Leased Premises to the extent necessary to make it
reasonably tenantable. The rent payable under this Lease during the unexpired
portion of the term shall be equitably abated to such an extent as may be fair
and reasonable under the circumstances based upon the area of the Leased
Premises which are untenantable. Lessee shall have no claim to the condemnation
award or proceeds in lieu thereof. Lessee may, in a separate legal action, make
any claims against the condemning authority permitted by Colorado law, but in no
event shall any award to Lessee reduce the award to Lessor.

                       ARTICLE 9.00 ASSIGNMENT OR SUBLEASE

     9.01 LESSOR ASSIGNMENT. Lessor shall have the right to sell, transfer or
assign, in whole or in part, its rights and obligations under this Lease and in
the building. Any such sale, transfer or assignment shall operate to release
Lessor from any and all liabilities under this Lease arising after the date of
such sale, assignment or transfer.

     9.02 LESSEE ASSIGNMENT. Lessee shall not assign, in whole or in part, this
Lease, or allow it to be assigned, in whole or in part, by operation of law or
otherwise or mortgage or pledge the same, or sublet the Leased Premises, in
whole or in part, without the prior written consent of Lessor, and Lessor may
consider the intended

                                       7

<PAGE>   30
use, parking requirements, and financial condition of the prospective assignee
or subtenant in deciding whether to consent, and in no event shall any such
assignment or sublease ever release Lessee or any guarantor from any obligation
or liability hereunder. No assignee or sublessee of the Leased Premises or any
portion thereof may assign or sublet the Leased Premises or any portion thereof.
Any assignment or subletting in violation hereof is void at Lessor's option.
[See Rider, Paragraph 7.]

     9.03 CONDITIONS OF ASSIGNMENT. If Lessee desires to assign or sublet all or
any part of the Leased Premises, it shall so notify Lessor at least thirty (30)
days in advance of the date on which Lessee desires to make such assignment or
sublease. Lessee shall provide Lessor with a copy of the proposed assignment or
sublease and such information as Lessor might request concerning the proposed
sublessee or assignee to allow Lessor to make informed judgments as to the
financial condition, reputation, operations and general desirability of the
proposed sublessee or assignee. Within fifteen days after Lessor's receipt of
Lessee's proposed assignment or sublease and all required information concerning
the proposed sublessee or assignee, Lessor shall have the following options: (1)
cancel this Lease as to the Leased Premises or portion thereof proposed to be
assigned or sublet; (2) consent to the proposed assignment or sublease, and, if
the rent due and payable by any assignee or sublessee under any such permitted
assignment or sublease (or a combination of the rent payable under such
assignment or sublease plus any bonus or any other consideration or any payment
incident thereto) exceeds the rent payable under this Lease for such space,
Lessee shall pay to Lessor all such excess rent and other excess consideration,
less any reasonable expenses incurred in obtaining the assignment or sublease,
within ten days following receipt thereof by Lessee; or (3) refuse, in its sole
discretion and judgment, to consent to the proposed assignment or sublease. Upon
the occurrence of an event of default, if all or any part of the Leased Premises
are then assigned or sublet, Lessor, in addition to any other remedies provided
by this Lease or provided by law, may, at its option, collect directly from the
assignee or sublessee all rents becoming due to Lessee by reason of the
assignment or sublease, and Lessor shall have a security interest in all
properties on the Leased Premises to secure payment of such sums. Any collection
directly by Lessor from the assignee or sublessee shall not be construed to
constitute a novation or a release of Lessee or any guarantor from the further
performance of its obligations under this Lease.

     9.04 SUBORDINATION. Lessee accepts this Lease subject and subordinate to
any recorded mortgage or deed of trust lien presently existing or hereafter
created upon the building or project and to all existing recorded restrictions,
covenants, easements and agreements with respect to the building or project.
Lessor is hereby irrevocably vested with full power and authority to subordinate
Lessee's interest under this Lease to any first mortgage or deed of trust lien
hereafter place on the Leased Premises, and Lessee agrees upon demand to execute
additional instruments subordinating this Lease as Lessor may require. If the
interests of Lessor under this Lease shall be transferred by reason of
foreclosure or other proceedings for enforcement of any first mortgage or deed
of trust lien on the Leased Premises, Lessee shall be bound to the transferee
(sometimes called the "Purchaser") under the terms, covenants and conditions of
this Lease for the balance of the term remaining, including any extensions or
renewals, with the same force and effect as if the Purchaser were Lessor under
this Lease, and, if requested by the Purchaser, Lessee agrees to attorn to the
Purchaser, including the first mortgagee under any such mortgage if it be the
Purchaser, as its Lessor. [See Rider, Paragraph 8].

     9.05 ESTOPPEL CERTIFICATES. Lessee agrees to furnish, from time to time,
within fifteen (15) days after receipt of a request from Lessor or Lessor's
mortgagee, a statement certifying, if applicable, the following: Lessee is in
possession of the Leased Premises; the Leased Premises are acceptable except for
defects which Lessor is obligated to repair, if any, specifying same; the Lease
is in full force and effect; the Lease is unmodified; Lessee claims no present
charge, lien, or claim of offset against rent; the rent is paid for the current
month, but is not prepaid for more than one month and will not be prepaid for
more than one month in advance; there is no existing default by reason of some
act or omission by Lessor; and such other matters as may be reasonably required
by Lessor or Lessor's mortgagee. Lessee's failure to deliver such statement, in
addition to being a default under this Lease, shall be

                                       8
<PAGE>   31
deemed to establish conclusively that this Lease is in full force and effect
except as declared by Lessor, that Lessor is not in default of any of its
obligations under this Lease, that Lessor has not received more than one month's
rent in advance, and such other matters as set forth in the estoppel.

                               ARTICLE 10.00 LIENS

                             Intentionally Deleted.

                       ARTICLE 11.00 DEFAULT AND REMEDIES

     11.01 DEFAULT BY LESSEE. The following shall be deemed to be events of
default by Lessee under this Lease: (1) Lessee shall fail to pay when due any
installment of rent or other payment required pursuant to this Lease and the
failure is not cured within ten (10) days after receipt of written notice;
provided, however, Lessee shall not be entitled to more than two (2) notices of
a delinquency in payment during any calendar year; (2) Lessee shall abandon any
substantial portion of the Leased Premises; (3) Lessee shall fail to comply with
any term, provision or covenant of this Lease, other than the payment of rent,
and the failure is not cured within twenty (20) days after receipt of written
notice by Lessee or if such default cannot reasonably be cured within twenty
(20) days, then Lessee has failed to commence to cure within such twenty (20)
day period and/or fails to diligently prosecute same to completion, or to the
extent that such default does not interfere with or disturb any other lessee or
violate law, then such cure period shall be thirty (30) days; (4) Lessee shall
file a petition or be adjudged bankrupt or insolvent under any applicable
federal or state bankruptcy or insolvency law or admit that it cannot meet its
financial obligations as they become due; or a receiver or trustee shall be
appointed for all or substantially all of the assets of Lessee; or Lessee shall
make a transfer in fraud of creditors or shall make an assignment for the
benefit of creditors; (5) Lessee shall vacate or abandon the Leased Premises
except as permitted by the Rider, Paragraph 9; or (6) Lessee shall do or permit
to be done any act which results in a lien being filed against the Leased
Premises or the building and/or project of which the Leased Premises are a part
and Lessee has not removed such lien within thirty (30) days after receipt of
notice of such filing.

     11.02 Remedies for Lessee's Default. Upon the occurrence of any event of
default set forth in this Lease, Lessor shall have the option to pursue any one
or more of the remedies set forth herein without any notice or demand. (1)
Lessor may enter upon and take possession of the Leased Premises, by picking or
changing locks if necessary, and lock out, expel or remove Lessee and any other
person who may be occupying all or any part of the Leased Premises without being
liable for any claim for damages, and relet the Leased Premises on behalf of
Lessee and receive the rent directly by reason of the reletting. Lessee agrees
to pay Lessor on demand any deficiency that may arise by reason of any reletting
of the Leased Premises; further, Lessee agrees to reimburse Lessor for any
expenditures made by it in order to relet the Leased Premises, including, but
not limited to, commissions, remodeling and repair costs. (2) Lessor may enter
upon the Leased Premises, by picking or changing locks if necessary, without
being liable for any claim for damages, and do whatever Lessee is obligated to
do under the terms of this Lease. Lessee agrees to reimburse Lessor on demand
for any expenses which Lessor may incur in effecting compliance with Lessee's
obligations under this Lease; further, Lessee agrees that Lessor shall not be
liable for any damages resulting to Lessee from effecting compliance with
Lessee's obligations under this Lease caused by the negligence of Lessor or
otherwise. (3) Lessor may terminate this Lease, in which event Lessee shall
immediately surrender the Leased Premises to Lessor, and if Lessee fails to
surrender the Leased Premises, Lessor may, without prejudice to any other remedy
which it may have for possession or arrearages in rent, enter upon and take
possession of the Leased Premises, by picking or changing locks if necessary,
and lock out, expel or remove Lessee and any other person who may be occupying
all or any part of the Leased Premises without being liable for any claim for
damages. (4) Lessor may, in addition to any other damages and sums due Lessor
including past due rents and attorneys' fees, elect to terminate the Lease, and
recover in addition to the above a sum equal to all Base Rent and additional
sums due for the remaining term of the Lease, as reasonably determined

                                       9
<PAGE>   32
by Lessor using existing estimates of Operating Expenses, less the reasonable
rental value of the Leased Premises over the remaining term. Lessee agrees to
pay on demand the amount of all loss and damage which Lessor may suffer by
reason of the default by Lessee including arising from the termination of this
Lease under this section, whether through inability to relet the Leased Premises
on satisfactory terms or otherwise. Notwithstanding any other remedy set forth
in this Lease, in the event Lessor has made rent concessions of any type or
character, or waived any Base Rent, and Lessee defaults at any time during the
terms of this Lease, the rent concessions, including any waived Base Rent, shall
be cancelled and the amount of the Base Rent or other rent concessions shall be
due and payable immediately as if no rent concessions or waiver of any Base Rent
had ever been granted. A rent concession or waiver of the Base Rent shall not
relieve Lessee of any obligation to pay any other charge due and payable under
this Lease including without limitation any sum due under Section 2.02.
Notwithstanding anything contained in this Lease to the contrary, this Lease may
be terminated by Lessor only by mailing or delivering written notice of such
termination to Lessee, and no other act or omission of Lessor shall be construed
as a termination of this Lease. All sums not paid when due shall accrue interest
at the Default Rate.

                            ARTICLE 12.00 RELOCATION

                             Intentionally Deleted.

                             ARTICLE 13.00 INSURANCE

     13.01 GENERAL REQUIREMENTS. Lessee shall, during its occupancy of the
Leased Premises and during the entire term hereof and any extended term, at its
sole cost and expense, obtain, maintain and keep in full force and effect the
following types and kinds of insurance:

     (a) Property Insurance upon property of every description and kind owned by
     the Lessee and located in the building or on the project or for which the
     Lessee is legally liable or installed by or on behalf of the Lessee,
     including, without limitation furniture, fixtures, fittings, installations,
     alterations, additions, partitions, fixtures and anything in the nature of
     a leasehold improvement in an amount of not less than the full replacement
     cost thereof on an all risk basis. In the event that there is a dispute as
     to the amount which comprises full replacement cost, the decision of the
     Lessor or the mortgagees of the Lessor shall be conclusive. Evidence of
     this insurance shall be provided on ACORD Form 27.

     (b) Commercial General Liability Insurance which shall include but not be
     limited to bodily injury, property damage, personal injury and broad form
     contractual liability and non-owned automobile liability in an amount of
     not less than $1,000,000 per occurrence and $2,000,000 in the aggregate
     combined single limit. The Lessor, the Lessor's agent, the Lessor's
     mortgagee and any other parties which the Lessor shall deem necessary shall
     be named as an additional insured therein as their respective interests may
     appear. This insurance shall be considered to be primary and
     noncontributory to any other insurance carried by the Lessor.

     (c) Automobile Liability Insurance (if applicable) in an amount of not less
     than $1,000,000 combined single limit for bodily injury and property damage
     providing coverage for all owned, non-owned and hired automobiles.

     (d) Workers' Compensation Insurance in the statutory form and amounts
     required by the State of Colorado and Employer's Liability Insurance in an
     amount of not less than:

             $500,000 bodily injury by accident, each accident
             $500,000 bodily injury by disease, policy limit
             $500,000 bodily injury by disease, each employee

                                       10

<PAGE>   33
     (e) Any other form or forms of insurance as the Lessor or the Lessor's
     mortgagees may reasonably require from time to time in form, in amounts and
     for insurance risks against which a prudent tenant would protect itself.

     (f) If Lessee or any contractor of Lessee performs any work on the Leased
     Premises, prior to the commencement of any such work, Lessee shall deliver
     to Lessor certificates issued by insurance companies licensed to do
     business in the State of Colorado, evidencing commercial general liability,
     workers' compensation, employer's liability, automobile liability and other
     insurance as required by Lessor and its mortgagees, in amounts and with
     companies reasonably satisfactory to Lessor, are in force and effect and
     maintained by all contractors and subcontractors engaged by Lessee to
     perform such work, and name where requested Lessor, Lessor's agent and
     Lessor's mortgagee as additional insureds.

              All policies shall be written with insurers licensed to do
     business in the State of Colorado and shall carry an A. M. Best rating of
     not less than AX (A Ten). The Lessee agrees that certificates of insurance
     evidencing the required insurance will be delivered to the Lessor no less
     than ten (10) days prior to each policy's annual renewal date. Such
     certificates will evidence that thirty (30) days written shall be sent to
     the Lessor prior to cancellation or nonrenewal of any policy, and shall
     evidence the Lessor, Lessor's agent and Lessor's mortgagee as additional
     insureds as required under subparagraph 13.01(b).

              The Lessee covenants and agrees that in the event of damage or
     destruction to the leasehold improvements in the Leased Premises covered by
     insurance as required to be taken out by the Lessee herein, and if the
     Lessor or Lessee do not terminate this Lease as specifically set forth in
     this Lease, the Lessee will use the proceeds of such insurance for the
     purpose of repairing or restoring such leasehold improvements at least up
     to and including the amounts of the unamortized Allowance. In the event
     that Lessor or Lessee are entitled to terminate the Lease, then if the
     premises have been damaged, Lessee shall pay to Lessor all of its insurance
     proceeds relative to Lessee's cabling costs, but in no event greater than
     the amount of Seventy-Two Thousand Dollars ($72,000).

     13.02 LESSOR'S INSURANCE. Lessor agrees to carry or cause to be carried
during the term hereof commercial general liability insurance covering bodily
injury, property damage and personal injury in an amount carried by prudent
owners of comparable properties and deemed prudent by the Lessor. Lessor may,
but shall not be obligated to, take out and carry any other form or forms of
insurance as it or the mortgagees of Lessor may reasonably determine to be
advisable. Notwithstanding any contribution by Lessee to the cost of insurance
premiums, Lessee acknowledges that it has no right to receive any proceeds from
any such insurance policies carried by Lessor, and that such insurance will be
for the sole benefit of Lessor, with no coverage for Lessee for any risk insured
against.

     13.03 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.

     16.01 WAIVER. Failure of Lessor to declare an event of default immediately
upon its occurrence, or delay in taking any action in connection with an event
of default, shall not constitute a waiver of the default, but Lessor shall have
the right to declare the default at any time and take such action as is lawful
or authorized under this Lease. Pursuit of any one or more of the remedies set
forth in Article 11.00 above shall not preclude pursuit of any one or more of
the other remedies provided elsewhere in this Lease or provided by law, nor

damages accruing to Lessor by reason of the violation of any of the terms,
provisions or covenants of this Lease. Failure by Lessor to enforce one or more
of the remedies provided upon an event of default shall not be deemed or
construed to constitute a waiver of the default or of any other violation or
breach of any of the terms, provisions and covenants contained in this Lease.

     16.02 ACT OF GOD. Neither Lessor nor Lessee shall be required to perform
any covenant or obligation in this Lease, or be liable in damages to the other

any of the terms, covenants, agreements or conditions contained in this Lease
and Lessor places in the hands of an attorney the enforcement of all or any

of the possession of the Leased Premises, Lessee agrees to pay Lessor's costs of
collection, including reasonable attorney's fees for the services of the
attorney, whether suit is actually filed or not.

     16.04 SUCCESSORS. This Lease shall be binding upon and inure to the benefit
of Lessor and Lessee and their respective heirs, personal representatives,
successors and assigns. It is hereby covenanted and agreed that should Lessor's
interest in the Leased Premises cease to exist for any reason during the term of
this Lease, then notwithstanding the happening of such event this Lease
nevertheless shall remain unimpaired and in full force and effect, and Lessee
hereunder agrees to attorn to the then owner of the Leased Premises.

     16.05 RENT TAX. If applicable in the jurisdiction where the Leased Premises
are situated, Lessee shall pay and be liable for all rental, sales and use taxes
or other similar taxes, if any, levied or imposed by any city, state, county or

the parties at the respective addresses set forth in Section 1.05. [See Rider,

     16.08 SUBMISSION OF LEASE. Submission of this Lease to lessee for signature
does not constitute a reservation of space or an option to lease. This Lease is
not effective until execution by and delivery to both Lessor and Lessee.

     16.09 CORPORATE AUTHORITY. If Lessee executes this Lease as a corporation,
each of the persons executing this Lease on behalf of Lessee does hereby
personally represent and warrant that Lessee is a duly authorized and existing
corporation, that Lessee is qualified to do business in the state in which the
Leased Premises are located, that the corporation has full right and authority
to enter into this Lease, and that each person signing on behalf of the
corporation is authorized to do so. In the event any representation or warranty
is false, all persons who execute this Lease shall be liable, individually, as
Lessee.

     16.10 SEVERABILITY. If any provision of this Lease or the application
thereof to any person or circumstance shall be invalid or unenforceable to any
extent, the remainder of this Lease and the application of such provisions to
other persons or circumstances shall not be affected thereby and shall be
enforced to the greatest extent permitted by law.

     16.11 LESSOR'S LIABILITY. If Lessor shall be in default under this Lease
and, it as a consequence of such default, Lessee shall recover a money judgment
against Lessor, such judgment shall be satisfied only out of the right, title
and interest of Lessor in the buildings as the same may then be encumbered and
neither Lessor nor any person or entity comprising Lessor shall be liable for
any deficiency. In no event shall Lessee have the right to levy execution
against any property of Lessor nor any person or entity comprising Lessor other
than its interest in the building as herein expressly provided. In no event,
however, shall Lessor be deemed in default unless it fails to cure such default
within twenty (20) days of written notice or if such default cannot reasonably
be cured within twenty (20) days, then Lessor shall not be deemed in default if
it has commenced to cure and diligently prosecutes same to completion.

     16.12 INDEMNITY. Lessor agrees to indemnify and hold harmless Lessee from
and against any liability or claim, whether meritorious or not, arising with
respect to any broker whose claim arises by, through or on behalf of Lessor.

                                    EXHIBIT C

                        LESSEE IMPROVEMENT WORK AGREEMENT

1.   Lessee Finish Allowance

     Lessor hereby grants to Lessee a Lessee Finish Allowance equal to $326,214
($9.00 per rentable square foot of the Leased Premises). The Lessee Finish
Allowance is to be used only for payment of the cost of preparing the space
plans and the final plans, including mechanical, electrical, plumbing,
engineering and structural drawings and of all other aspects necessary to
complete the final plans, and payment for carpet, paint and other improvements
set forth in the final plans; and any construction, management fee equal to 3%
of the total construction costs. Said Lessee Finish Allowance shall be credited
against the aggregate cost of Lessee Work, as hereinafter defined. Any unused
portion of the allowance, up to $1.00 per rentable square foot, may be used by
Lessee as (i) a rent credit against the first rent dollars owing under this
Lease, or (ii) up to $2.00 per rentable square foot may be applied towards
Lessee's cabling costs. If Lessee requires Lessee Work in excess of the Lessee
Finish Allowance, then Lessee agrees that it shall pay for said work in excess
of the Lessee Finish Allowance in accordance with the terms for payment of
Additional Work as more specifically set forth in Paragraph 2 hereof, including
provision for profit and overhead.

2.   Lessee Work

     Lessor agrees to complete the work depicted in the space plan attached
hereto as Exhibit C-1 (the "Lessee Work") in a good and workmanlike manner,
subject, however, to extensions equal to the delays suffered by Lessor and
caused by strikes, lockouts, fire or other casualty loss, acts of God,
unavailability of materials, hostile or war-like action, riot or other causes
beyond Lessor's reasonable control. If Lessee shall require any changes to the
attached plans and specifications or the Lessee Work depicted in such attached
plans and specifications ("Additional Work"), then, providing Lessor agrees to
such changes, Lessee shall pay, within thirty (30) days of the billing after
work has been completed. Lessor agrees to perform such Additional Work up to
$3.00 per rentable square foot. All costs and expenses associated with Lessor's
Additional Work shall bear interest at the rate of 2.9% per month.

3.   Commencement of Rent

     Lessee's obligation to pay Rent under the Lease shall not commence until
the date the Leased Premises are Ready for Occupancy; provided, however, that if
Lessor shall be delayed in rendering the Leased Premises Ready for Occupancy
beyond the Commencement Date set out in Section 1.03 of this Lease as a result
of one or more of the following:

     (a) Lessee's failure to devote the time or furnish the information required
in connection with the space plan for the Lessee Work; or

     (b) Lessee's failure to timely deposit the estimated costs for the
Additional Work within the time period specified in Paragraph 2 above; or

     (c) Lessee's changes in the Lessee Work, in the space plan relating
thereto, or in the plans for the Additional Work (notwithstanding Lessor's
approval of any such changes); or

     (d) Any other act or omission by Lessee or its agents;

then and in any such event, Lessee's obligation to commence the payment of Rent
under the Lease on the Commencement Date provided for in Section 1.03 shall not
be affected or deferred on account of such delay.

                                      C-1

<PAGE>   42

4.   Alternate Commencement Date

     If Lessor is unable to cause the Leased Premises to be Ready for Occupancy
by the Commencement Date for reasons other than those set out in subsection (a)
through (d) of Paragraph 3 above then the Commencement Date of the Lease shall
be on the first date the Leased Premises are Ready for Occupancy; provided,
however if the date the Leased Premises are Ready for Occupancy is not the first
day of a month, then the Commencement Date shall be the first day of the month
immediately following the date the Leased Premises are Ready for Occupancy. The
period between the date the Leased Premises are Ready for Occupancy and the
Commencement Date shall be deemed to be the Interim Lease Term and Lessee shall
be obligated to pay Rent for such Interim Lease Term on a pro rata basis based
on the Base Rent for the first full month of the Term and Lessee shall hold the
Leased Premises during the Interim Lease Term under all of the other terms and
conditions of this Lease. In the event the Commencement Date set out in Section
1.03 of the Lease is changed as provided for in this Paragraph 4 then (i) if the
Leased Premises are Ready for Occupancy after the Commencement Date set out in
Section 1.03 of the Lease then the Expiration Date of the Lease as provided for
in Section 1.03 of the Lease shall be extended such that beginning with the
adjusted Commencement Date the Term shall extend for the number of months set
out in Section 1.03 of the Lease, or (ii) if the Leased Premises are Ready for
Occupancy prior to the Commencement Date set out in Section 1.03 of the Lease
then the Commencement Date shall be adjusted as provided for in this Paragraph
4, however the Expiration Date shall remain as set out in Section 1.03 of the
Lease. In either such event, Lessee shall, at Lessor's request, execute a
Memorandum of Commencement Date in which the parties specify the Commencement
Date and Expiration Date of the Lease.

     "Ready for Occupancy" as used herein shall mean the date on which Lessor
shall have substantially completed all its work outlined in this Work Letter.
The issuance of a Certificate of Occupancy (or its equivalent) for the Leased
Premises or a certificate from Lessor's architect or space planner certifying
substantial completion of the work shall conclusively control the date the
Leased Premises are substantially complete, the date on which the Leased
Premises are Ready for Occupancy and the date Lessee's obligation to pay Rent
commences. Lessor agrees to use its best efforts to provide Lessee with at least
fifteen (15) days prior notice of the date the Leased Premises are expected to
be Ready for Occupancy. Lessor's undertaking to provide fifteen (15) days prior
notice to Lessee shall not change, alter, or otherwise affect Lessee's
obligations under this Lease to take occupancy of the Leased Premises when the
same are Ready for Occupancy.

5.   Miscellaneous

     (a) Except to the extent otherwise indicated herein, the initially
capitalized terms used in this Lessee Improvement Work Agreement shall have the
meanings assigned to them in the Lease.

     (b) The terms and provisions of this Lessee Improvement Work Agreement are
intended to supplement and are specifically subject to all the terms and
provisions of the Lease. In the event of conflict between the terms of this
Lessee Improvement Work Agreement and the Lease, then the provisions of the
Lease shall govern.

     (c) Prior to the date the Leased Premises are Ready for Occupancy, Lessor's
contractor and Lessee shall inspect the Leased Premises and jointly complete a
"punch list" of incomplete or defective work and thereafter Lessor shall
exercise due diligence to cause such punch list items to be completed.

     (d) This Lessee Improvement Work Agreement may not be amended or modified
other than by supplemental written agreement executed by authorized
representatives of the parties hereto.

     (e) Lessee shall not be entitled to any credits, whether in the form of
materials or money, for unused work or materials.

                                      C-2

<PAGE>   43

     (f) All standard Lessee Work shall be performed in accordance with Exhibit
C-1.

     (g) Lessor's approval of Lessee's plans or the Lessee Work shall create no
responsibility or liability on the part of Lessor for their completeness, design
sufficiency, or compliance with all laws, rules and regulations of governmental
agencies or authorities, including but not limited to the Americans with
Disabilities Act.

     caustics, or any flammable, explosive or hazardous material without written
     consent of Lessor. Nothing herein shall prohibit the use of a microwave
     oven.

5.   Lessor will not be responsible for lost or stolen personal property,

     request. Lessee shall not leave any vehicle in a state of disrepair
     (including without limitation, flat tires) on the Leased Premises or

     of a vehicle shall create any liability on Lessor or be deemed to interfere

     and posted speed limits must be observed. Parking is prohibited in areas

     and are not transferable. Every person is required to park and lock his
     vehicle. All responsibility for damage to vehicles or persons is assumed by
     the owner of the vehicle or its driver.

     equipment, or dispatch or receipt by Lessee of any merchandise or materials
     which requires use of elevators or stairways, or movement through the
     building entrances or lobby, shall be restricted to hours designated by
     Lessor. All such movement shall be under supervision of Lessor and carried
     out in the manner agreed between Lessee and Lessor by prearrangement before
     performance. Such prearrangement will include determination by Lessor of
     time, method, and routing of movement and limitations imposed by safety or
     other concerns which may prohibit any article, equipment or any other item
     from being brought into the building. Lessee assumes, and shall indemnify
     Lessor against, all risks and claims of damage to persons and properties
     arising in connection with any said movement.

16.  Lessor shall not be liable for any damages from the stoppage of elevators
     for necessary or desirable repairs or improvements or delays of any sort or
     duration in connection with the elevator service.

     written approval of the Lessor, which shall not be unreasonably withheld.

18.  Lessee agrees to cooperate and assist Lessor in the prevention of
     canvassing, soliciting and peddling within the building or project.

19.  Lessor reserves the right to exclude from the building or project, between
     the hours of 6:00 p.m. and 7:00 a.m. on weekdays and at all hours on
     Saturday, Sunday and legal holidays, all persons who are not known to the
     building or project security personnel and who do not present a pass to the
     building signed by the Lessee. Each Lessee shall be responsible for all
     persons for whom he supplies a pass.

20.  It is Lessor's desire to maintain in the building or project the highest
     standard of dignity and good taste consistent with comfort and convenience
     for Lessees. Any action or condition not meeting this high standard should
     be reported directly to Lessor. Your cooperation will be mutually
     beneficial and sincerely appreciated. Lessor reserves the right to make
     such other and further reasonable rules and regulations as in its judgment
     may from time to time be necessary, for the safety, care and cleanliness of
     the Leased Premises and for the preservation of good order therein.

                              (FOR RECEIVING ONLY)

     THIS SATELLITE DISH LICENSE is made and entered into this _______, day of
_______, 1997 by and between North Creek I-III L.P., a Delaware limited
partnership ("Lessor") and MCI Systemhouse Corp., a Delaware corporation
("Lessee").

                              W I T N E S S E T H:

     WHEREAS, Lessor and Lessee have entered into a Lease dated _______________
(the "Lease") for premises located in that certain building known as North Creek
II located in Colorado Springs, State of Colorado (the "Building"); and

     WHEREAS, Lessee is desirous of locating a satellite dish on the roof of the
Building; and

     WHEREAS, Lessor is willing to permit same only upon the following terms and
conditions.

     NOW, THEREFORE, in consideration of the premises and other good and
valuable consideration, the parties hereto agree as follows:

     1. Grant of License. Provided Lessee provides Lessor with detailed
information regarding the satellite dish for Lessor's prior review and approval
(which may be given or withheld by Lessor in its sole discretion), Lessor grants
to Lessee a non-exclusive license for the term of the Lease, said term being
more specifically described in Section 3 below, for the purpose of installing,
maintaining and operating a satellite dish not to exceed two (2) meters (the
"Satellite") on a portion of the roof located on the Building as shown on
Appendix __ attached hereto (the "Roof Space"). The actual location of the Roof
Space shall be in Lessor's reasonable discretion. The grant of this license is
for the sole benefit of and use by Lessee and the Satellite's use shall be
personal to and may not be assigned, sublet or transferred in whole or in part
except pursuant to an assignment or sublease according to the Lease to be used
solely by such sublessee or assignee for its own purposes. No third party may
use the Satellite nor may Lessee receive any fees or other payment for the use
of such Satellite. Lessor makes no representation or warranty as to the fitness
for any purpose of the Roof Space and shall have no liability of any kind or
nature directly or indirectly arising from or related to the Satellite and
Related Equipment as hereinafter defined.

     2. Installation. Lessee shall be permitted to install the one (1)
Satellite. All installation expenses shall be at Lessee's sole cost and expense.
Installation expenses shall include, but not be limited to, all of the
incremental costs related to repairing or replacing the roof of the Building in
conjunction with such installation and the cost of installation of a walkway
providing access to the Satellite (the "Walkway"). Prior to commencing the
installation of the Satellite and any related equipment, conduits, cables and
materials located on the Roof Space or in other parts of the Building
(collectively, the "Related Equipment"), Lessee shall submit plans and
specifications regarding installation of the Satellite and any Related Equipment
to Lessor for review and reasonable approval, which approval shall not be
unreasonably withheld. Lessee shall have a reasonable right of access to the
chases, telephone and electrical closets located in the Building for purposes of
installing, repairing and maintaining the Related Equipment, provided, however,
such access shall be subject to the reasonable approval of Lessor, which
approval shall not be unreasonably withheld. The Related Equipment to be
installed in the telephone and electrical closets shall consist of
_________________________ and shall not occupy more than ___________ cubic
inches, provided that such space is available within the Building prior to the
execution of this License. The plans and specifications shall include load
factors, electrical platforms leading to the Satellite and any other
specifications as Lessor may require. Lessee agrees that Lessor may require
certain aesthetic specifications concerning the

                                      G-1
<PAGE>   50

appearance of the Satellite and any Related Equipment, which specifications
shall be in the reasonable discretion of Lessor.

     3. Term. Lessee's right to use the Roof Space shall commence on the date on
which Lessee commences installation of the Satellite or any of the Related
Equipment, and shall terminate upon the termination of the Lease (the "Term") as
such Lease may be extended. Upon the termination hereof, the Satellite, the
Walkway and the Related Equipment shall be removed by Lessee at Lessee's
expense, and Lessee shall repair any damage to the building and roof caused by
the removal and restore the roof.

     4. License Fee.

                              Intentionally Deleted

     5. Reroofing and Repair. Lessee acknowledges that Lessor may be repairing
or installing a new roof on the Building during the term of this License.
Lessor, the roofing contractor or consultant and Lessee shall coordinate the
repair and/or reroofing of the Roof and Lessee shall pay in advance on demand
all increases in costs of repair or reroofing arising from or related to the
Satellite, the Walkways and the Related Equipment. Furthermore, to the extent
that the Satellite, Walkways or any Related Equipment need to be dismantled,
relocated, repaired or replaced in conjunction with such reroofing or repair,
all costs and expenses shall be borne by Lessee, and Lessor shall have no
liability in connection therewith, including, without limitation, any
interruption in service.

     6. Permits. Prior to commencing the installation of the Satellite, Walkways
and/or Related Equipment, Lessee shall, at its own cost and expense, obtain each
and every permit including building permits and approvals of any applicable
architectural control committee for same and deliver same to Lessor. Lessor
makes no representations or warranties with respect to zoning or any other
approvals. If Lessee cannot obtain such necessary permits or such permits affect
the Building or the Roof Space in any way by means of additional requirements,
then this License shall be deemed null and void and of no further force and
effect, unless Lessor in writing waives the conditions set forth herein.

     7. Repair and Maintenance of Satellite and Related Equipment. Lessee agrees
that it shall keep and maintain the Satellite, Walkways and the Related
Equipment in good condition and repair, at Lessee's sole cost and expense, in
such a manner so as not to conflict or interfere with the use of other
facilities installed in the Building and consistent with first-class office
buildings in Colorado Springs, Colorado. Furthermore, Lessee agrees that it
shall not damage nor shall it permit any damage to the roof or the Roof Space or
the Building in conjunction with the Satellite and the Related Equipment. Lessee
agrees that the Satellite and the Related Equipment shall be of such types and
frequencies that will not cause interference with other antennas or dishes in
the North Creek Complex in operation at the time of Lessee's installation. In
the event the Satellite or the Related Equipment cause such interference, Lessee
shall immediately take all steps necessary to correct and eliminate the
interference. If Lessee cannot eliminate the interference within a reasonable
time of notification thereof, it shall remove the Satellite and Related
Equipment causing the interference. Lessee shall use its best efforts to notify
any telephone and/or electrical service persons of the location of the Related
Equipment in the Building in order to minimize any interference with such
equipment.

     8. Repair and Maintenance of the Roof. Lessee hereby acknowledges and
agrees that Lessor, its agents, employees, contractors or anyone else permitted
by Lessor to be on the roof of the Building may from time to time inspect,
repair, replace or maintain the roof or any part or parts thereof, or install
additional improvements or fixtures on the said roof. Lessee shall maintain the
Walkway at it sole expense, except Lessor shall be liable for the cost of
repairs or maintenance to the Satellite, Walkway and Related Equipment caused by
Lessor's misconduct or gross negligence.

     9. Compliance with Law and Warranties. Lessee, at Lessee's sole cost and
expense, agrees to install, keep, maintain, operate and remove the Satellite,
Walkways and the Related Equipment in accordance with all applicable laws,
rules, regulations, statutes, ordinances or other requirements of any kind or
nature of any governmental or quasi-governmental authority or the requirements
of Lessor's insurance underwriters and in compliance with any roofing
warranties.

     10. Alterations and Mechanic's Liens. Lessee shall not without the prior
written consent of Lessor, which consent shall not be unreasonably withheld,
make any alterations, improvements or additions to the Satellite, the Related
Equipment or any other materials related thereto. Lessee agrees that it shall
not alter, add to or move the Satellite, the Walkway or Related Equipment
without Lessor's consent, which consent shall not be unreasonably withheld by
Lessor. In the event that Lessee desires to perform any alterations,
improvements, additions, repairs or other work on the Satellite, Walkways or the
Related Equipment, Lessee shall first submit to Lessor a written request
therefor outlining the repairs, alterations, or other matters which Lessee is
requesting Lessor's consent. The work necessary to perform any of the repairs or
alterations under this section shall be done by employees or contractors
approved in advance by Lessee subject to written contracts containing all
conditions Lessor may reasonably impose, including insurance provisions. Lessee
agrees that it shall defend and hold Lessor and the Building harmless from all
costs, damages, liens, for labor, services or materials related to any work done
on the additions by Lessee.

     11. Damage by Lessee. Subject to the waiver of subrogation as set forth in
Section 13.03 of the Lease, which is incorporated herein by reference, if the
Building, Building Complex, elevators, boilers, engines, pipes, electrical
apparatus, or any other elements of the Building or the Building roof or any
portion thereof, become damaged or destroyed through any act of Lessee, its
servants, agents, employees, contractors or anyone permitted by Lessee to be
working in the Building or on the Satellite, Walkways or the Related Equipment,
whether or not such act was a result of the negligence or willful misconduct of
Lessee or any such party, then the cost of any repairs, replacements,
alterations and all damages incurred by Lessor shall be borne by Lessee who
shall, within thirty (30) days of demand, pay the same to Lessor.

     12. Lessee's Insurance. Lessee shall with respect solely to the Satellite,
during the entire term of this License, at its sole cost and expense, obtain,
maintain, and keep in full force and effect insurance with coverages, amounts,
with companies and in form reasonably acceptable to Lessor naming Lessor and
Mortgagees of Lessor as insureds thereunder. If the cost of Lessor's insurance
increases as a result directly or indirectly of this License, the Satellite or
the Related Equipment then Lessee shall pay the costs of such increases directly
to Lessor upon demand.

     13. Attorneys' Fees. In the event of any litigation or arbitration between
Lessor and Lessee to enforce any provision of this License or any right of
either party hereto, the unsuccessful party to such litigation or arbitration
shall pay to the successful party all costs and expenses, including reasonable
attorneys' fees, incurred therein.

     14. Indemnification; Release. From and after the Effective Date, Lessee
hereby agrees to indemnify, defend, and save Lessor harmless from and against
all claims, demands, liability, loss, cost, damage, or expense, including
attorneys' fees, incurred by or asserted against Lessor as a result of or
arising out of this License including the installation, use or existence of the
Satellite, Walkways and Related Equipment by Lessee. This indemnity shall
survive expiration or termination of this License and/or the Lease for a period
of time not to exceed one (1) year. Lessee hereby irrevocably releases Lessor,
its agents, employees, invitees or contractors, from any claims, damages,
expenses or costs of any kind or nature, whether known or unknown, arising from
or related to this License or any act or the negligence of Lessor, its
employees, agents, invitees or contractors, excepting, however, any costs,
claims or damages relating to the gross negligence or willful acts of Lessor, it
being understood and agreed that the Satellite and Related Equipment are at the
sole risk, cost and expense of Lessee.

payable hereunder, and such failure shall continue for thirty (30) days after

had within such thirty (30) day period, Lessee shall not in good faith have
commenced such performance within such thirty (30) day period and shall not
thereafter diligently proceed to completion;

     16. Remedies of Lessor. If any one or more events of default shall happen,
then Lessor shall have the right, at Lessor's election, to terminate this
License by written notice to Lessee, and to pursue any other remedy provided in
law or in equity for damages incurred by Lessor.

tenant's use of their Premises and equipment therein nor may the antenna or dish
cause or pose any possible health risk of any kind or nature.

     ADDITIONAL PROVISIONS TO THE LEASE:

14.  EXTENSION OPTIONS

     Notwithstanding any provisions contained in this Lease to the contrary, in
addition to the initial term hereof, Lessee shall have the right to extend the
term of this Lease for an additional term of five (5) years (the "EXTENSION
PERIOD") commencing on the date immediately following the expiration date and
ending on the date immediately preceding the sixth (6) anniversary of the
commencement date of the Extension Period. If Lessee elects to exercise such
option, it shall do so by giving notice of such election to Lessor no sooner
than one (1) year and no later than six (6) months before the beginning of
the Extension Period. Such Extension Period shall be on the same terms and
conditions as are set forth herein except for rent which shall be 100% of the
then current Fair Market Rent ("FMR") as hereinafter defined. The word "TERM" as
used in this Lease and this Rider shall include the above mentioned Extension
Period.

     If Lessee gives notice in accordance with the provisions of this Paragraph,
and the parties are unable to agree to the Fair Market Rent within thirty (30)
days after receipt of the notice from Lessor setting forth the Base Rent then
Lessee at its sole option and as its sole right or remedy may either (i)
initiate the appraisal process provided for herein by giving notice to that
effect to the Lessor, or (ii) revoke its exercise of its option to extend. If
Lessee initiates an appraisal then the Lessee shall specify in such notice the
name and address of the Appraiser designated on its behalf. Lessor shall have
ten (10) business days from receipt of such notice of appraisal to appoint its
own Appraiser and notify Lessee thereof. All Appraisers designated shall be real
estate brokers licensed in the State of Colorado with at least ten (10) years
experience in office building leasing in Colorado Springs, Colorado. The third
appraiser must be impartial and must not have been directly engaged by Lessor or
Lessee for two and one half years preceding the appraisal process. If the Lessor
fails to notify the Lessee of the appointment of its Appraiser within the time
above specified, then the appointment of the second Appraiser shall be made in
the same manner as hereinafter provided for the appointment of a third Appraiser
in a case where the two Appraisers appointed hereunder and the parties are
unable to agree upon such appointment. The two Appraisers so chosen shall meet
within ten (10) days after the second Appraiser is appointed, and if the two
Appraisers shall not agree, they shall together appoint a third Appraiser. If
the two Appraisers are unable to agree upon such appointment within thirty (30)
days after the appointment of the second Appraiser, then either party, on behalf
of both and no notice to the other, may apply for the appointment of a third
Appraiser to the District Court Judge for El Paso County.

     The majority of the Appraisers shall determine the Fair Market Rent for the
Leased Premises and render a written report of their determination to both
Lessor and Lessee within thirty (30) days of the appointment of the second
Appraiser or thirty (30) days of the appointment of the third Appraiser, if such
third Appraiser is appointed pursuant to the provisions hereof, and
determination of the Fair Market Rent by the majority of the Appraisers shall be
binding and conclusive on both Lessor and Lessee.

     Each party shall pay the fees and expenses of the one of the two original
Appraisers appointed by or for such party, and the fees and expenses of the
third Appraiser and all other expenses (not including the attorneys' fees,
witness fees and similar expenses of the parties, which shall be borne
separately by each of the parties) of the appraisal process shall be borne by
the parties equally.

     In the event Lessor or Lessee initiates the appraisal process and as of the
commencement date of the Extension Period the amount of the Fair Market Rent has
not been determined, Lessee shall pay the base rent payable by Lessee hereunder
as of the Expiration Date of the Initial Term and when such determination has
been made, it shall be retroactive as of the commencement date of the Extension
Period and any deficiency or overpayment shall be paid by Lessee to Lessor, or
if applicable Lessor to Lessee, within thirty (30) days after the date of such
determination.

                                       4

<PAGE>   56
     Lessee's occupancy of the Leased Premises during the Extension Period shall
be on the same terms and conditions as are in effect immediately prior to the
expiration date of the initial term of this Lease, provided, however, (i) base
rent shall be as determined herein; (ii) Lessee shall have no further right to
any allowances, tenant finish, renewals or monetary concessions, if any,
included in Base Rent.

     If Lessee does not send notice pursuant to the provisions hereof, the
option to extend shall be of no further force or effect and shall be deemed
deleted from this Lease. Time shall be of the essence as to Lessee's delivery of
notice.

     If this Lease is extended, then Lessor or Lessee can request the other
party hereto to execute a supplemental agreement setting forth the exercise of
Lessee's right to extend the term of this Lease, the last day of the Extension
Period, and the base rent for the respective Extension Period.

     For purposes hereof, Fair Market Rent shall mean the base rent for a
reasonably comparable renewal term of a comparable size lease in El Paso County,
Colorado, for a building of similar size, age, condition and amenities.

15.  QUIET ENJOYMENT

     Notwithstanding any provision contained in this Lease to the contrary,
Lessor covenants and agrees with Lessee that upon Lessee's paying the rent and
any additional rent and observing and performing all of the terms, covenants and
conditions on Lessee's part to be observed and performed, Lessee may peaceably
and quietly enjoy from claims of parties claiming by or through Lessor (1) the
Leased Premises hereby demised, and (2) such other rights as Lessee is granted
under this Lease subject to the terms of the Lease.

16.  AUTHORITY TO EXECUTE

     Notwithstanding any provision contained in this Lease to the contrary, the
parties hereto represent and warrant that each has the authority to enter into
this Lease and that the signatories hereto are authorized representatives of
Lessor and Lessee respectively.

17.   PARKING

     Provided Lessee is not in default and subject to casualty, condemnation and
applicable laws, Lessee shall at all times during the term of this Lease, at no
additional cost to Lessee, including any extensions or renewals thereof, have up
to 3 parking spaces for each 1000 square feet of the Leased Premises.

18.  CONNECTIVITY

     Lessor hereby grants to Lessee the right, at its sole cost and expense, to
install two (2) six (6) inch conduits between the North Creek II Building and
the North Creek III Building for the placement of fiber optic risers and cables
between the respective Leased Premises of Lessee, along with accompanying access
to existing chases and other building facilities in order to install cables
measuring 2-2 1/2 inches in diameter. Lessee shall submit all plans and
specifications for installation of its conduits to Lessor for Lessor approval
prior to beginning any construction, which approval shall not be unreasonably
withheld or delayed. Lessee shall at its sole cost and expense keep, maintain
and repair the conduits in good condition and repair. The conduit is subject to
existing easements, and any applicable laws.

     In addition, upon the execution of the attached Satellite Dish License
Agreement (Exhibit G), Lessor hereby grants to Lessee the right to install one
(1) receiving only satellite dish on the roof of the Building, along with
accompanying access to existing chases and other building facilities in order to
install cables measuring approximately 2-2 1/2 inches in diameter to the
satellite dish. Lessee shall submit all plans and specifications for
installation of the satellite dish and accompanying cables to Lessor for Lessor
approval prior to beginning any construction, which approval shall not be

                                       5
<PAGE>   57

unreasonably withheld or delayed. Upon termination of Lessee's right to use such
conduit, Lessee shall remove any of its cabling and fiber optics, clean the
conduit and surrender the conduit to Lessor, which shall remain the property of
Lessor.

19.  COLLOCATION OF EQUIPMENT

     Lessor hereby grants to Lessee the right to locate equipment owned by
Lessee's customers upon the Leased Premises; provided, however, that:

   (i)   the placement of such equipment upon the Leased Premises will not
         create in the third party customer a possessory interest in the Leased
         Premises;

   (ii)  all equipment placed upon the Leased Premises by a third party customer
         shall remain the personal property of the third party customer;
         provided prior written notice thereof is given to Lessor, the third
         party customer releases Lessor from any and all claims arising from the
         presence of the equipment in on or about the Leased Premises, and the
         third party customer agrees to remove the equipment within one (1) day
         of receipt of notice, and repair any damage if the Lessee's rights to
         possession have been terminated.

   (iii) Lessee shall indemnify and hold Lessor harmless from any and all
         damages, liabilities and other claims arising from the existence of the
         third party customer's equipment upon the Leased Premises in accordance
         with Section 7.03 of this Lease during the term of this Lease and any
         extensions thereof.

   (iv)  in the event Lessor deems the Lessee's placement of such equipment upon
         the Leased Premises does create in the third party customer a
         possessory right in the Leased Premises, Lessee agrees to execute a
         sublease agreement with Lessor covering the space utilized by Lessee's
         customer's equipment within the Leased Premises.

   (v)   all costs and expenses by Lessor arising from or relating to such
         equipment shall be borne by Lessee and payable upon demand including
         reasonable attorneys fees and costs.

   (vi)  the existence or placement of the equipment in on or about the Leased
         Premises shall not violate this Lease including the rules and
         regulations, and any insurance requirements.

5.   RIDER TO SECTION 6.02 - LESSEE IMPROVEMENTS

     Notwithstanding the provisions of Section 6.02, Lessor agrees to not
unreasonably withhold consent to alterations within the Leased Premises which do
not affect either the structure of the building (including the roof) or the
building systems, which systems include without limitation electrical, plumbing
and HVAC. Lessee may install vending machines in the Leased Premises for
exclusive use of Lessee's employees and Lessee shall be responsible for the cost
of any additional maintenance or utilities required for such machines. Upon the
prior written approval of Lessor, Lessee may retain its own licensed contractor
for all work within the Leased Premises, provided that such contractor meets all
reasonable insurance requirements of Lessor and such contractor would not
violate or invalidate any outstanding warranties for work.

6.   RIDER TO SECTION 6.03 - MECHANICS LIEN

     Notwithstanding any provision contained in this Lease to the contrary,
Lessee shall have a period of thirty (30) days from and after Lessee's receipt
of notice of the filing of any such mechanic's or materialmen's lien within
which to post a bond or to cause such lien to be released of record before
Lessor may exercise its rights under this section.

7.   RIDER TO SECTION 9.02 - ASSIGNMENT

     Notwithstanding anything to the contrary contained hereinabove, Lessee
shall have the right, without obtaining Lessor's prior written consent, to
assign or sublease all or any portion of the Leased Premises to the following
parties on the following conditions:

          a.  Any subsidiary or affiliate of Lessee, provided Lessee owns a
     substantial interest in such affiliate or subsidiary;

          b.  Any parent corporation of Lessee;

          c.  Any subsidiary or affiliate of Lessee's parent corporation if such
     parent owns a substantial interest in such subsidiary or affiliate; or

          d.  Any corporation into which Lessee may be merged or consolidated or
     which purchases all or substantially all of the assets or stock of Lessee;
     provided that the resulting corporation has as net worth at least equal to
     Lessee's net worth as of the date hereof;

and provided that:

          (1) Lessee continues to remain primarily liable on its obligations set
     forth herein;

          (2) Any such subtenant and/or assignee shall assume and be bound by
     all obligations of Lessee for payment of all amounts of rental and other
     sums and the performance of all covenants required by Lessee pursuant to
     this Lease; and

          (3) Any such subtenant and/or assignee intends to operate the Leased
     Premises in accordance with the usage restrictions of this Lease and under
     the same name as Lessee.

Not less than thirty (30) days subsequent to the effective date of such
transaction, Lessee shall provide Lessor with copies of the documents evidencing
such transaction and such evidence as Lessor may reasonably require to establish
that such transaction falls within the terms and provisions of this
subparagraph. All subletting and assignments shall be on forms approved by
Lessor in advance. If Lessor's then standard subletting or assignment form is
not utilized then Lessee shall pay Lessor's reasonable costs to have such
sublease or assignment forms reviewed. Any subletting

                                    ("Sublease") between MCI SYSTEMHOUSE CORP.,
                                    a Delaware corporation ("SUBLESSOR") and
                                    CHANNELPOINT, INC., a Delaware corporation
                                    ("SUBLESSEE") concerning certain premises
                                    ("PREMISES") commonly known as Suite 200 in
                                    North Creek II, 5755 Mark Dabling Boulevard,
                                    Colorado Springs, Colorado

Ladies and Gentlemen:

         Reference is hereby made to your request for consent to the subletting
contemplated by the Sublease.

         We hereby consent to such subletting, subject to the following
understandings, agreements and conditions, notwithstanding anything contained in
the Sublease to the contrary:

         1.       Neither this consent nor the terms of the Sublease modifies,
                  amends, waives or affects any of the terms, covenants,
                  conditions, provisions or agreements of the lease from the
                  undersigned to Sublessor dated on or about June 30, 1997, as
                  may have been amended ("LEASE"), nor affects Sublessor's
                  obligations thereunder, which Lease shall continue to apply to
                  all the space covered by the Lease and the use and occupancy
                  thereof. The Sublease is subject and subordinate at all times
                  to this consent and to the Lease and all of its terms,
                  covenants, conditions, provisions and agreements.

         2.       This consent shall not be construed to create a
                  landlord-tenant relationship or privity of contract or estate
                  between the undersigned and Sublessee.

         3.       Nothing contained herein shall be construed as a consent to,
                  approval of, or ratification by the undersigned of any of the
                  particular provisions of the Sublease or as a representation
                  or warranty by the undersigned in respect thereof. The
                  undersigned is not passing on the terms, covenants and
                  conditions of the Sublease and is not assuming any obligations
                  under the Sublease.

         4.       Neither the Sublease, nor this consent thereof shall be
                  construed as a consent by the undersigned to any further
                  subletting either by Sublessor or by Sublessee.

         5.       This consent is not assignable, nor shall this consent be a
                  consent to any amendment, modification, extension or renewal
                  of the Sublease, without the undersigned's prior written
                  consent.

         6.       Intentionally omitted.

         7.       Sublessor and Sublessee covenant and agree that under no
                  circumstances shall the undersigned be liable for any
                  brokerage commission or other charge or expense in connection
                  with the Sublease and both Sublessor and Sublessee agree to
                  indemnify the undersigned, its directors, officers, agents,
                  shareholders and employees against same and against any cost
                  or expense (including, without limitation, attorney's fees and
                  disbursements) incurred by the undersigned, its directors,
                  officers, agents, shareholders and employees in resisting any
                  claim for any such brokerage commission.

         8.       If for any reason the term of the Lease shall terminate, the
                  Sublease shall automatically be terminated, and on or prior to
                  the date of such termination of the Sublease, Sublessee shall
                  quit and surrender the Premises to the undersigned in
                  accordance with all applicable provisions of the Lease.

         9.       The execution of this consent by Sublessor and by Sublessee
                  shall indicate their joint and several confirmation of the
                  foregoing conditions and their agreement to be bound thereby.
                  The failure of Sublessor and Sublessee to execute this consent
                  and deliver it to the undersigned within 30 days of the date
                  hereof shall render this consent void ab initio and of no
                  force or effect, without any further action of the
                  undersigned.

         10.      The parties hereby acknowledge that any special rights under
                  the Lease that, by their terms are personal or non-assignable,
                  including, but not limited to, extension, expansion,
                  relocation, early termination, signage, or rights that by
                  their terms are personal or non-assignable, are not being
                  assigned by the Sublease (notwithstanding anything to the
                  contrary contained therein), and, to the extent that such
                  rights by their terms no longer apply after a sublease, then
                  such rights shall be of no further force or effect.

                           the undersigned and Sublessee in the form attached
                           hereto as Exhibit A wherein Sublessee agrees to
                           delete Section 3 of the Rider to that certain lease
                           dated March 25, 1997 between Sublessee, as Tenant and
                           the undersigned, as Landlord, for certain other
                           premises at North Creek II;

                  (b)      execution of a Tenant Estoppel Certificate by

                  (c)      execution of a Tenant Estoppel Certificate by

                           Building in the form attached hereto as Exhibit C;
                           and

                           Corporation at North Creek III in the form attached
                           hereto as Exhibit D.

         In the event that Sublessor fails or refuses to execute and deliver to
the undersigned any or all of the foregoing documents (executed by the
appropriate party) together with the fully executed copy of this Consent to
Sublease, then this Consent to Sublease shall, at the sole option of the
undersigned, be null and void.

document described and dated as follows First Amendment to Lease dated May 23,
1997 (collectively, and as amended herein, the "Lease").

         B. The parties mutually desire to amend the Lease on and subject to the
terms and conditions hereof.

         NOW, THEREFORE, in consideration of the mutual terms and conditions
herein contained, the parties hereby agree as follows:

         1. AMENDMENT. The parties agree that the Lease shall be amended in
accordance with the following terms and conditions:

                                 BUILDING LEASE

     THIS LEASE is made this 12th day of July 1999, between WESTMOOR BUSINESS
PARK LTD., LLLP, a Colorado limited liability limited partnership, ("Landlord")
and CHANNELPOINT, INC., a Colorado corporation ("Tenant").

     1. Premises: Landlord hereby leases to Tenant those certain premises
designated on the floorplan(s) attached hereto as Exhibit A and incorporated
herein by this reference (the "Premises"), consisting of a total of
approximately 9,040 square feet of space (Rentable Area) on the second floor(s),
suite(s) 210 of the building known as Building Three ("Building"), located in
Westmoor Technology Park ("Westmoor Technology Park") at 10155 Westmoor Drive,
Westminster, Colorado 80021 located on the real property more particularly
described on Exhibit B attached hereto and incorporated herein by this
reference, together with a non-exclusive right, subject to the provisions
hereof, to use all appurtenances thereunto, including, but not limited to,
parking areas and any other areas designated by Landlord for use by tenants of
the Building (the Building, real property on which the same is situated, parking
areas, other areas and appurtenances are hereinafter collectively sometimes
called the "Building Complex"). For purposes of this Lease, "Rentable Area" of
the Premises shall mean and refer to the area of the Premises, as determined by
Landlord's architect, utilizing the methodology of calculation outlined on
Exhibit A-l consistently applied in the Building. The exact square footage of
the Premises shall be calculated by Landlord's architect at the time the
construction documents for the Premises have been completed. This Lease is
subject to the terms, covenants and conditions set forth herein and Tenant and
Landlord each covenant as a material part of the consideration for this Lease to
keep and perform each and all of said terms, covenants and conditions to be kept
and performed by them.

     2. Term:

         (a) The term of this Lease shall be for sixty (60) months (the "Primary
Lease Term") commencing at 12:01 a.m. on September 1, 1999 (the "Commencement
Date") and terminating at 12:00 midnight on August 31, 2004 (the "Termination
Date"), unless sooner terminated pursuant to the terms hereof. In the event the
Premises are not "Ready for Occupancy" as such term is defined in Paragraph 20
hereof, the Commencement Date shall mean and refer to the date the Premises are
Ready for Occupancy.

         (b) If, as a result of the postponement or acceleration of the
Commencement Date, the Primary Lease Term would begin other than on the first
day of the month, Tenant shall pay proportionate rent at the same monthly rate
set forth herein (also in advance) for such partial month and all other terms
and conditions of this Lease shall be in force and effect during such partial
month, and the end of the Primary Lease Term hereof shall be adjusted to a date
which is the last day of the month sixty (60) months after the Commencement
Date. Tenant agrees to execute and deliver to Landlord, in form attached hereto
as Exhibit C, an Estoppel and Commencement Date Certificate, within ten (10)
days of the date the Primary Lease Term commences, certifying as to the actual
commencement and termination dates of the Primary Lease Term, the rent
commencement date, if different, and such other matters as may be required by
Landlord.

     3. Rent: Tenant shall pay to Landlord, rent for the Premises ("Base Rent")
as follows:

<TABLE>
<CAPTION>
          Period (by month)       Annual Base Rent          Monthly Base Rent          Rate/RSF
          -----------------       ----------------          -----------------          --------
<S>                              <C>                       <C>                      <C>
              1 - 36                 $124,752.00               $10,396.00               $13.80
              37 - 60                $135,961.60               $11,330.13               $15.04
</TABLE>

<PAGE>   7

All installments of Base Rent shall be payable in advance, on the first (1st)
day of each calendar month during the term hereof. Rent for the first and last
months of the term hereof shall be prorated based upon the number of days during
each of said months that the Lease term was in effect. One monthly installment
of Base Rent shall be due and payable on the date of execution of this Lease by
Tenant. All Base Rent shall be paid without notice, demand, deduction or offset,
at the office of Landlord or to such other person or at such other place as
Landlord may designate in writing. Tenant shall pay to Landlord as "Additional
Rent" all other sums due under this Lease. All payments of Base Rent and
Additional Rent shall be paid in United States currency.

     4. Security Deposit: It is agreed that Tenant, concurrently with the
execution of this Lease, has deposited with Landlord, and will keep on deposit
at all times during the term hereof, the sum of Ten Thousand Seven Hundred
Sixty-nine Dollars and No/100 ($10,769.00), the receipt of which is hereby
acknowledged, as security for the payment by Tenant of the rent and all other
sums herein agreed to be paid and for the faithful performance of all the terms,
conditions and covenants of this Lease. If, at any time during the term hereof,
Tenant shall be in default in the performance of any provisions of this Lease,
Landlord shall have the right, but shall not be obligated, to use said deposit,
or so much thereof as necessary, in payment of any rent in default,
reimbursement of any expense incurred by Landlord, and in payment of any damages
incurred by the Landlord by reason of Tenant's default. In such event, Tenant
shall, on written demand of Landlord, forthwith remit to Landlord a sufficient
amount in cash to restore said deposit to its original amount. In the event said
deposit has not been utilized as aforesaid, said deposit, or as much thereof as
has not been utilized for such purposes, shall be refunded to Tenant without
interest, within sixty (60) days after the termination of this Lease upon full
performance of this Lease by Tenant and vacation of the Premises by Tenant.
Landlord shall have the right to commingle said deposit with other funds of
Landlord. Landlord may deliver the funds deposited herein by Tenant to any
purchaser of Landlord's interest in the Premises in the event such interest is
sold, and thereupon Landlord shall be discharged from further liability with
respect to such deposit. If the claims of Landlord exceed the amount of said
deposit, Tenant shall remain liable for the balance of such claims.

     5. Rent Adjustment:

         (a) The following terms shall have the following meanings with respect
to the provisions of this Paragraph 5:

            (1) "Building Rentable Area" shall mean all rentable space available
for lease in the Building, as determined by Landlord's architect, utilizing the
methodology of calculation as outlined on Exhibit A-1 and consistently applied
to the Building. If there is a significant change in the aggregate Building
Rentable Area, of a permanent nature, as a result of an addition to the
Building, partial destruction thereof or similar circumstance, Landlord's
accountants shall determine and make an appropriate adjustment to the provisions
herein.

            (2) "Tenant's Pro Rata Share" shall mean a fraction, the numerator
of which is the Rentable Area of the Premises (i.e., 9,040 square feet) and the
denominator of which is the Building Rentable Area (i.e., 97,916 feet), and is
equal to 9.23%. At such time, if ever, any space is added to or subtracted from
the Premises pursuant to the terms of this Lease, Tenant's Pro Rata Share shall
be increased or decreased accordingly.

            (3) "Operating Expenses" shall mean:

                A. All operating expenses of any kind or nature which are
necessary, ordinary or customarily incurred with respect to the operation and
maintenance of the Building Complex as determined in accordance with generally
accepted accounting principles and shall include, but not be limited to:

                   (i) Costs of supplies, including but not limited to the cost
of "relamping" all tenant lighting as the same may be required from time to
time;

                                       2
<PAGE>   8

                   (ii) Costs incurred in connection with obtaining and
providing energy for the Building Complex, including but not limited to costs of
propane, butane, natural gas, steam, electricity, solar energy and fuel oils,
coal or any other energy sources as well as costs for heating, ventilation, and
air conditioning services ("HVAC");

                   (iii) Costs of water and sanitary and storm drainage
services;

                   (iv) Costs of janitorial services;

                   (v) Costs of Security services or systems;

                   (vi) Costs of general maintenance and repairs, including
costs under HVAC and other mechanical maintenance contracts; and repairs and
replacements of equipment used in connection with such maintenance and repair
work;

                   (vii) Costs of maintenance and replacement of landscaping;
and costs of maintenance, repair, striping and repaving of parking areas, common
areas, plazas and other areas used by tenants of the Building Complex,
exclusively or in common with others, including trash and snow removal;

                   (viii) Any fees, costs or assessments imposed by any property
owners association;

                   (ix) Insurance premiums, including fire and all-risk
coverage, together with loss of rent endorsement; public liability insurance;
and any other insurance carried by Landlord on the Building Complex or any
component parts thereof;

                   (x) Labor costs, including wages and other payments, costs to
Landlord of worker's compensation and disability insurance, payroll taxes,
welfare fringe benefits and all legal fees and other costs or expenses incurred
in resolving any labor disputes;

                   (xi) Professional building management fees;

                   (xii) Salaries of on site employees hired by Landlord or its
property manager;

                   (xiii) Legal, accounting, inspection and other consultation
fees (including, without limitation, fees charged by consultants retained by
Landlord for services that are designed to produce a reduction in Operating
Expenses or reasonably to improve the operation, maintenance or state of repair
of the Building Complex) incurred for the normal prudent operation of the
Building Complex;

                   (xiv) The costs of capital improvements and structural
repairs and replacements made in or to the Building Complex or the cost of any
machinery or equipment installed in the Building Complex in order to conform to
any applicable laws, ordinances, rules, regulations or orders of any
governmental or quasi-governmental authority having jurisdiction over the
Building Complex (herein, "Required Capital Improvement"); the costs of any
capital improvements and structural repairs and replacements designed primarily
to reduce Operating Expenses (herein, "Cost Savings Improvements"); and a
reasonable annual reserve for all other capital improvements and structural
repairs and replacements reasonably necessary to permit Landlord to maintain the
Building as an office building. The expenditures for Required Capital
Improvements and Cost Savings Improvements shall be amortized over the useful
life of such capital improvement or structural repair or replacement (as
determined by Landlord's accountants), provided that the amortized amount of any
Cost Savings Improvement shall be limited in any year to the reduction in
Operating Expenses as a result thereof; and

                                       3
<PAGE>   9

                   (xv) "Real Estate Taxes" including all real property taxes
and assessments levied against the Building Complex by any governmental or
quasi-governmental authority, including any taxes, assessments, surcharges, or
service or other fees of a nature not presently in effect which shall hereafter
be levied on the Building Complex as a result of the use, ownership or operation
of the Building Complex or for any other reason, whether in lieu of or in
addition to any current real estate taxes and assessments; provided, however,
that any taxes which shall be levied on the rentals of the Building Complex
shall be determined as if the Building Complex were Landlord's only property
and provided further, that in no event shall the term "Taxes and Assessments",
as used herein, include any federal, state or local income taxes levied or
assessed on Landlord, unless such taxes are a specific substitute for real
property taxes; such term shall, however, include gross taxes on rentals and
expenses incurred by Landlord for tax consultants and in contesting the amount
or validity of any such Taxes or Assessments (all of the foregoing are
collectively referred to herein as "Taxes"). "Assessments" shall include any and
all so-called special assessments, license tax, business license fee, business
license tax, commercial rental tax, levy, charge 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 or
the Building Complex, or against any legal or equitable interest of Landlord
therein. For the purposes of this Lease, any special assessment shall be deemed
payable in such number of installments as is permitted by law, whether or not
actually so paid. If the Building Complex has not been fully assessed as a
completed project, for the purposes of computing the Real Estate Taxes for any
adjustment required herein, the same shall be increased by Landlord's
accountants, in accordance with their estimate of what the assessment will be,
upon full completion of the Building Complex, including installation of all
tenant finish items. Any difference in actual Real Estate Taxes in any year and
the estimated Real Estate Taxes used by Landlord in the calculation of Operating
Expenses paid by Tenant shall be reflected in the reconciliation of Operating
Expenses described in Paragraph 5(e) below.

                   (xvi) Any other expense which under generally accepted
accounting principles would be considered a normal maintenance or operating
expense.

     If Landlord selects an accrual accounting basis for calculating Operating
Expenses, Operating Expenses shall be deemed to have been paid when such
expenses have accrued in accordance with generally accepted accounting
principles.

                B. Operating Expenses shall expressly exclude Landlord's income
taxes; leasing commissions, advertising and promotional expenses; interest on
debt or amortization payments on any mortgages or deeds of trust except as
provided in Paragraph 5(a)(3)(A)(xii); costs of repairs or other work occasioned
by fire, windstorm or other casualty to the extent of insurance proceeds
received; costs of repairs or other work to the Building or Building systems
covered by warranty; and any other expense which under generally accepted
accounting principles would not be considered a normal maintenance or operating
expense, except as otherwise specifically provided herein.

         (b) If, during any year or portion thereof, the Building is less than
ninety-five percent (95%) occupied, those Operating Expenses which vary with the
occupancy levels in the Building shall be adjusted by Landlord to reflect the
level of Operating Expenses which reasonably would be incurred by Landlord in
the event the Building were ninety-five percent (95%) occupied; similarly, Real
Estate Taxes shall be adjusted by Landlord to reflect a fully occupied, fully
assessed Building, and the Building revenue shall be treated as if there were no
"free rent" periods or periods of rental abatement in making such adjustment
(such adjustments as described in this sentence being referred to herein as a
"Gross-Up"). Further, Operating Expenses shall be retroactively adjusted by
Landlord to include the cost of all maintenance contracts incurred by Landlord
during the second year of operation of the Building and any costs of operation
or maintenance in the Building which would have been incurred during the Base
Year but for the fact that such costs and/or expenses were covered by warranties
covering the Building during the initial twelve (12) months of the Building's
operation (or such longer warranty period as Landlord may have procured), it
being the intent of the parties that Operating Expenses (i) shall not be
artificially low by virtue of the fact that any Building components were subject
to contract warranties, and (ii) shall reflect the entire costs of ownership and
operation of the Building during a normal twelve (12) month period, such
adjustment being agreed to

                                       4
<PAGE>   10

by the parties. Landlord shall not recover through Operating Expenses any item
of cost more than once. Landlord shall, at all times during the entire term of
this Lease, operate, manage, maintain and repair the Building in a lawful,
efficient and businesslike manner in accordance with sound property management
practices.

         (c) From and after the Commencement Date, Tenant shall pay to Landlord
as Additional Rent during the balance of the term hereof an estimate of Tenant's
Pro Rata Share of Operating Expenses as reasonably estimated by Landlord,
payable monthly, at the rate of one twelfth (1/12) thereof, on the same date and
at the same place Base Rent is payable, with an adjustment to be made between
the parties at a later date as hereinafter provided. Landlord shall deliver to
Tenant, as soon as practicable following the end of any calendar year, an
estimate of the Operating Expenses for the new calendar year (the "Budget
Sheet"). Until receipt of the Budget Sheet, Tenant shall continue to pay its
monthly Tenant's Pro Rata Share of Operating Expenses based upon the estimate
for the preceding calendar year. To the extent that the Budget Sheet reflects an
estimate of Tenant's Pro Rata Share of Operating Expenses for the new calendar
year greater than the amount actually paid to the date of receipt of the Budget
Sheet for the new calendar year, Tenant shall pay such amount to Landlord within
thirty (30) days of receipt of the Budget Sheet. Upon receipt of the Budget
Sheet, Tenant shall thereafter pay the amount of its monthly Tenant's Pro Rata
Share of Operating Expenses as set forth in the Budget Sheet. As soon as
practicable following the end of any calendar year, but not later than May 1st,
Landlord shall submit to Tenant a statement in reasonable detail describing the
computations of the Operating Expenses setting forth the exact amount of
Tenant's Pro Rata Share of Operating Expenses for the calendar year just
completed (the "Statement"), and the difference, if any, between the actual
Tenant's Pro Rata Share of Operating Expenses for the calendar year just
completed and the estimated amount of Tenant's Pro Rata Share of Operating
Expenses paid by Tenant to Landlord. Notwithstanding the foregoing, Landlord's
failure to deliver the Statement to Tenant on or before May 1st, shall in no way
serve as a waiver of Landlord's rights under this Paragraph. To the extent that
the actual Tenant's Pro Rata Share of Operating Expenses for the period covered
by the Statement is higher than the estimated Tenant's Pro Rata Share of
Operating Expenses which Tenant previously paid during the calendar year just
completed, Tenant shall also pay to Landlord such balance within thirty (30)
days following receipt of the Statement from Landlord. To the extent that the
actual Tenant's Pro Rata Share of Operating Expenses for the period covered by
the Statement is less than the estimated Tenant's Pro Rata Share of Operating
Expenses which Tenant previously paid during the calendar year just completed,
Landlord shall credit the excess against any sums then owing or next becoming
due from Tenant under the Lease. In addition to the above Operating Expenses,
Tenant shall pay monthly upon receipt of Landlord's invoice, the Tenant's
electric usage for the Premises, as determined by the check meter installed as
provided for in paragraph 7(b).

         (d) If the Lease term hereunder covers a period of less than a full
calendar year during the first or last calendar years of the term hereof,
Tenant's Pro Rata Share of Operating Expenses for such partial year shall be
calculated by proportionately reducing the Operating Expenses to reflect the
number of months in such year during which Tenant leased the Premises (the
"Adjusted Operating Expenses"). The Adjusted Operating Expenses shall then be
compared with the actual Operating Expenses for said partial year to determine
the amount, if any, of any increases in the actual Operating Expenses for such
partial year over the Adjusted Operating Expenses. Tenant shall pay Tenant's Pro
Rata Share of any such increases within ten (10) days following receipt of
notice thereof.

         (e) Tenant shall have the right at its own expense and at a reasonable
time (after written notice to Landlord) within thirty (30) days after receipt of
the Statement to audit Landlord's books relevant to the Additional Rent due
under this Paragraph 5. In the event Tenant does not audit Landlord's books and
deliver the results thereof to Landlord within said 30-day period, the terms and
amounts set forth in the Statement shall be deemed conclusive and final and
Tenant shall have no further right to adjustment. In the event Tenant's
examination reveals that an error has been made in Landlord's determination of
Tenant's Pro Rata Share of Operating Expenses and Landlord agrees with such
determination, then the amount of such adjustment shall be payable by Landlord
or Tenant, to the other party as the case may be. In the event Tenant's
examination reveals an error has been made in Landlord's determination of
Tenant's Pro Rata Share of Operating Expenses, and Landlord disagrees with the
results thereof, Landlord shall have thirty (30) days to obtain an audit from an
accountant of its choice to determine Tenant's Pro Rata Share of Operating
Expenses. In the event Landlord's accountant and Tenant's accountant are unable
to reconcile their audits, both accountants shall mutually agree upon a third
accountant, whose determination of Tenant's Pro Rata Share

                                       5
<PAGE>   11

of Operating Expenses shall be conclusive. In the event the amount of error by
Landlord is determined to be ten percent (10%) or more, the reasonable costs of
the three audits made pursuant to this subparagraph shall be paid by Landlord.
In the event the amount of error by Landlord is determined to be less than ten
percent (l0%), the reasonable costs of the three audits made pursuant to this
subparagraph shall be paid by Tenant.

         (f) Landlord's failure during the Lease term to prepare and deliver any
statements or bills, or Landlord's failure to make a demand under this Paragraph
or under any other provision of this Lease shall not in any way be deemed to be
a waiver of, or cause Landlord to forfeit or surrender its rights to collect any
items of Additional Rent which may have become due pursuant to this Paragraph
during the term of this Lease. Tenant's liability for all Additional Rent due
under this Paragraph 5 shall survive the expiration or earlier termination of
this Lease.

     6.  Character of Occupancy:

         (a) The Premises are to be used for general offices and product
demonstration to clients not inconsistent with the character and type of tenancy
found in comparable office buildings of a similar size, use and character in the
Northwest Suburban area of Denver, Colorado and for no other purpose without the
prior written consent of Landlord. Tenant shall, at its sole expense, comply
with all laws applicable to its use of the Premises and obtain all permits or
licenses required for the transaction of business at the Premises.

         (b) Tenant shall not suffer nor permit the Premises nor any part
thereof to be used in any manner, nor anything to be done therein, nor suffer or
permit anything to be brought into or kept therein, which would in any way (i)
make void or voidable any fire or liability insurance policy then in force with
respect to the Building Complex, (ii) make unobtainable from reputable insurance
companies authorized to do business in the state of Colorado any fire insurance
with extended coverage, or liability, elevator, boiler or other insurance
required to be furnished by Landlord under the terms of any lease or mortgage to
which this Lease is subordinate at standard rates, (iii) cause or in Landlord's
reasonable opinion be likely to cause physical damage to the Building Complex or
any part thereof, (iv) constitute a public or private nuisance, (v) impair, in
the opinion of Landlord, the appearance, character or reputation of the Building
Complex, (vi) discharge objectionable fumes, vapors or odors into the Building
air conditioning system or into the Building flues or vents not designed to
receive them or otherwise in such manner as may unreasonably offend other
occupants of the Building, (vii) impair or interfere with any of the Building
services or impair or interfere with or tend to impair or interfere with the use
of any of the other areas of the Building by, or occasion discomfort, or
annoyance to Landlord or any of the other tenants or occupants of the Building
Complex, any such impairment or interference to be based upon the judgment of
Landlord, (viii) increase on an ongoing periodic basis the pedestrian traffic in
and out of the Premises or the Building above an ordinary level, (ix) create
waste in, on or around the Premises, Building, or Building Complex, or (x) make
any noise or set up any vibration which will disturb other tenants, except in
the course of permitted repairs or alterations at times permitted by Landlord.

         (c) Tenant shall not use the Premises nor permit anything to be done in
or about the Premises or Building Complex which will in any way conflict with
any law, statute, ordinance, protective covenants affecting the Building Complex
or governmental or quasi-governmental rules or regulations now in force or which
may hereafter be enacted or promulgated. Tenant shall give written notice within
two (2) days from receipt thereof to Landlord of any notice it receives of the
violation of any law or requirement of any public authority with respect to the
Premises or the use or occupation thereof. Landlord shall give prompt notice to
Tenant of any notice it receives relative to the violation by Tenant of any law
or requirement of any public authority with respect to the Premises or the use
or occupation thereof.

         (d) Tenant, by execution of this Lease and occupancy of the Premises,
agrees to comply with any declaration of covenants, conditions and restrictions
for the Westmoor Technology Park, now or hereafter entered into, as the same may
be amended from time to time ("Covenants") as applicable to Tenant's use and
enjoyment of the Premises, Building Complex and Westmoor Technology Park. In
addition to all rights available to Landlord hereunder, in the event Landlord is
obligated to pay to the association created pursuant to the Covenants
("Association") any fines, assessments, charges or other amounts on account of
any act or omission of Tenant, its

                                        6
<PAGE>   12
agents, employees or invitees, Tenant shall, upon demand, reimburse Landlord for
such amounts, together with interest thereon at the Interest Rate. Landlord
shall deliver to Tenant a copy of the Covenants at such time as the same are
recorded in the real property records of Jefferson County, Colorado ("Records"),
and Landlord shall deliver copies of the amendments thereto at such time as such
amendments are recorded in the Records.

     7. Services and Utilities:

         (a) Landlord agrees, without charge except as provided herein with
respect to Operating Expenses, and in accordance with standards from time to
time prevailing for buildings in the Westmoor Technology Park area, to furnish
water to the Building for use in lavatories and drinking fountains (and to the
Premises if the plans for the Premises so provide); during ordinary business
hours to furnish such heated or cooled air to the Premises as may, in the
judgment of Landlord, be reasonably required for the comfortable use and
occupancy of the Premises provided that Tenant complies with the recommendations
of Landlord's engineer or other duly authorized representative, regarding
occupancy and use of the Premises; to provide janitorial services for the
Premises (including such interior and exterior window washing as may be
required), such janitorial services to be provided five days a week, except for
"Holidays" as herein defined; to cause electric current to be supplied for
lighting the Premises and public halls; and to furnish such snow removal
services to the Building Complex as may, in the judgment of Landlord, be
reasonably required for safe access to the Building Complex.

         (b) Landlord shall provide electricity for normal office purposes
including but not limited to fluorescent and incandescent lighting, including
task and task ambient lighting systems and for normal office equipment including
but not limited to duplicating (reproduction) machines, communications and audio
visual equipment, vending machines, personal computers (provided they do not
require any additional voltage or special electrical requirements) executive
kitchen equipment, internal communication systems (which may include piped-in
music) and Tenant's data room. Tenant shall install, as part of its tenant
improvements, a check meter to determine the amount of electric current usage
Tenant is utilizing for the Premises. The cost of such usage, and check meter,
including but not limited to monitoring, installation and repair thereof, shall
be paid by Tenant.

         (c) If Tenant requires water in excess of that usually furnished or
supplied for use in the Premises as general office space, Tenant shall first
procure the consent of Landlord for the use thereof. Tenant agrees to pay to
Landlord such amounts as Landlord determines are necessary to cover the costs of
such increased use of water, including, but not limited to, the cost of
installation, monitoring, maintenance and repair of any check meter or other
instrument necessary to measure the use of additional water.

         (d) Tenant agrees that Landlord shall not be liable for failure to
supply any heating, air conditioning, elevator, electrical, janitorial, lighting
or other services during any period when Landlord uses reasonable diligence to
supply such services, or during any period Landlord is required to reduce or
curtail such services pursuant to any applicable laws, rules or regulations, now
or hereafter in force or effect, it being understood and agreed to by Tenant
that Landlord may discontinue, reduce or curtail such services, or any of them
at such times as it may be necessary by reason of accident, unavailability of
employees, repairs, alterations, improvements, strikes, lockouts, riots, acts of
God, application of applicable laws, statutes, rules and regulations, or due to
any other happening beyond the reasonable control of Landlord. In the event of
any such interruption, reduction or discontinuance of Landlord's services,
Landlord shall not be liable for damages to persons or property as a result
thereof, nor shall the occurrence of any such event in any way be construed as
an eviction of Tenant, or operate to release Tenant from any of Tenant's
obligations hereunder, except in the event that a discontinuance of services(s)
renders the Premises unuseable and continues for a period of more than seven
(7) days, in which case Base Rent shall be abated until said services(s) are
restored.

         (e) Whenever heat generating machines or equipment are used by Tenant
in the Premises which affect the temperature otherwise maintained by the air
conditioning system, Landlord reserves the right to install supplementary air
conditioning units in the Premises in the event Landlord's independent
consulting engineer determines same are necessary as a result of Tenant's use of
lights or equipment which generate heat loads in excess

                                        7
<PAGE>   13
of those for which the HVAC system is designed and the cost therefor, including
the cost of installation, operation and maintenance thereof, shall be paid by
Tenant to Landlord upon demand by Landlord.

         (f) In the event that Tenant has any special or additional electrical
or mechanical requirements related to its use of the Premises, any such
electrical or mechanical equipment must be located within the Premises. Such
electrical or mechanical requirements, for the purposes hereof, shall include by
way of example, but not limitation, any internal telephone system. The foregoing
shall in no way be construed as granting to Tenant additional rights to use any
such special or additional electrical or mechanical equipment in its Premises
without the prior written consent of Landlord. Any additional cost or expense
related to or resulting from such electrical or mechanical requirements shall be
the sole obligation of Tenant.

         (g) If Tenant requires HVAC service beyond ordinary business hours
(hereafter "After Hours Usage"), such service must be requested from the
Building manager at least twenty-four (24) hours prior thereto. After Hours
Usage shall only be supplied in one-half floor increments of the Building, for a
minimum of four (4) hours with increments of one half (1/2) hour thereafter.
Tenant shall reimburse Landlord, as Additional Rent, for all costs and expenses
for After Hours Usage in an amount equal to $38.00 per hour. If more than one
tenant is being furnished After Hour Usage during the same period, the charge to
Tenant shall be appropriately pro rated to reflect such multiple use of After
Hour Usage. The After Hours Usage rate may be modified by Landlord as utility
rates change.

     8. Quiet Enjoyment: Subject to the provisions of this Lease, Landlord
covenants that Tenant on paying the rent and performing the covenants of this
Lease on its part to be performed shall and may peacefully and quietly have,
hold and enjoy the Premises for the term of this Lease. Landlord shall not be
responsible for the acts or omissions of any other tenant or third party which
may interfere with Tenant's use and enjoyment of the Premises. In the event of
any transfer or transfers of Landlord's interest in the Premises or in the real
property of which the Premises are a part, other than a transfer for security
purposes only, the transferor shall be automatically relieved of any and all
obligations and liabilities on the part of Landlord accruing from and after the
date of such transfer.

     9. Maintenance and Repairs:

         (a) Notwithstanding any other provisions of this Lease, Landlord shall
repair and maintain in a good condition the structural portions of the Building,
including the elevators, plumbing, air conditioning, heating and electrical
systems installed or furnished by Landlord, unless such maintenance and repairs
are caused in part or in whole by the act, neglect, fault or omission of Tenant,
its agents, servants, employees, licensees or invitees, in which case Tenant
shall pay to Landlord, on demand, the cost of such maintenance and repairs less
the amount of any insurance proceeds received by Landlord on account thereof, if
applicable. Landlord shall also maintain and keep in good order and repair the
Building roof; the curtain wall, including all glass connections at the
perimeter of the Building; all exterior doors, including any exterior plate
glass within the Building; the Building ventilating systems; elevators; Building
telephone and electrical closets; public portions of the Building or Building
Complex, including but not limited to the landscaping, walkways, and upper floor
lobbies and corridors, parking structure, and interior portions of the Building
above and below grade which are not covered by leases.

         (b) Tenant, at Tenant's sole cost and expense, except for services
furnished by Landlord pursuant to Paragraph 7 hereof, shall maintain, in good
order, condition and repair, the Premises, including the interior surfaces of
the ceilings (if damaged or discolored due in whole or in part to the act,
neglect, omission or fault of Tenant), walls and floors, all doors, interior
glass partitions or glass surfaces (not exterior windows) and pipes, electrical
wiring, switches, fixtures and other special items, subject to the provisions of
Paragraph 15 hereof. In the event Tenant fails to so maintain the Premises in
good order, condition and repair, Landlord shall give Tenant notice to do such
acts as are reasonably required to maintain the Premises. In the event Tenant
fails to promptly commence such work and diligently pursue it to completion,
then Landlord shall have the right, but shall not be required, to do such acts
and expend such funds at the expense of Tenant as are reasonably required to
perform such work. The funds so expended plus twenty percent (20%) of such
amounts as an overhead/administrative charge shall be due and payable

                                       8
<PAGE>   14
by Tenant within ten (10) days after receipt of Landlord's invoice therefor.
Landlord shall have no liability to Tenant for any damage, inconvenience or
interference with the use of the Premises by Tenant as a result of performing
any such work.

     10. Alterations and Additions:

         (a) Tenant shall make no alterations, additions or improvements to the
Premises or any part thereof without obtaining the prior written consent of
Landlord with the exception of additions or improvements that cost less than
$5,000.00 and are nonstructural in nature. Tenant shall submit any such request
to Landlord at least thirty (30) days prior to the proposed commencement date of
such work. Landlord may impose, as a condition to such consent, and at Tenant's
sole cost, such requirements as Landlord may deem necessary in its judgment,
including without limitation, the manner in which the work is done, a right of
approval of the contractor by whom the work is to be performed and the times
during which the work is to be accomplished, approval of all plans and
specifications and the procurement of all licenses and permits. Landlord shall
be entitled to post notices on and about the Premises with respect to Landlord's
non-liability for mechanics' liens and Tenant shall not permit such notices to
be defaced or removed. Tenant further agrees not to connect any apparatus,
machinery or device to the Building systems, including electric wires, fiber
optic systems, telecommunication systems, cable trays, duct work, water pipes,
fire safety, heating and mechanical systems, without the prior written consent
of Landlord.

         (b) All alterations, improvements and additions to the Premises,
including, by way of illustration but not by limitation, all counters, screens,
grilles, special cabinetry work, partitions, paneling, carpeting, drapes or
other window coverings and light fixtures, shall be deemed a part of the real
estate and the property of Landlord and shall remain upon and be surrendered
with the Premises as a part thereof without molestation, disturbance or injury
at the end of the Lease term, whether by lapse of time or otherwise, unless
Landlord, by notice given to Tenant no later than fifteen (15) days prior to the
end of the term, shall elect to have Tenant remove all or any of such
alterations, improvements or additions (excluding non-movable office walls), and
in such event, Tenant shall promptly remove, at its sole cost and expense, such
alterations, improvements and additions and restore the Premises to the
condition in which the Premises were prior to the making of the same, reasonable
wear and tear excepted. Any such removal, whether required or permitted by
Landlord, shall be at Tenant's sole cost and expense, and Tenant shall restore
the Premises to the condition in which the Premises were prior to the making of
the same, reasonable wear and tear excepted. All movable partitions, machines
and equipment which are installed in the Premises by or for Tenant, without
expense to Landlord, and can be removed without structural damage to or
defacement of the Building or the Premises, and all furniture, furnishings and
other articles of personal property owned by Tenant and located in the Premises
(all of which are herein called "Tenant's Property") shall be and remain the
property of Tenant and may be removed by it at any time during the term of this
Lease. However, if any of Tenant's Property is removed, Tenant shall repair or
pay the cost of repairing any damage to the Building or the Premises resulting
from such removal. All additions or improvements which are to be surrendered
with the Premises shall be surrendered with the Premises, as a part thereof, at
the end of the term or the earlier termination of this Lease.

         (c) If Landlord permits persons requested by Tenant to perform any
alterations, repairs, modifications or additions to the Premises, then 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 where the
Premises are located evidencing that worker's compensation, public liability
insurance and property damage insurance, all in amounts, with companies and on
forms satisfactory to Landlord, are in force and maintained by all such
contractors and subcontractors engaged by Tenant to perform such work. All such
policies shall name Landlord as an additional insured and shall provide that the
same may not be canceled or modified without thirty (30) days prior written
notice to Landlord.

         (d) Tenant, at its sole cost and expense, shall cause any permitted
alterations, decorations, installations, additions or improvements in or about
the Premises to be performed in compliance with all applicable requirements of
insurance bodies having jurisdiction, and in such manner as not to interfere
with, delay, or impose

                                       9
<PAGE>   15

any additional expense upon Landlord in the construction, maintenance or
operation of the Building, and so as to maintain harmonious labor relations in
the Building.

     11. Entry by Landlord:

         Landlord and its agents shall have the right to enter the Premises at
all reasonable times and upon reasonable notice for the purpose of examining or
inspecting the same, to supply any services to be provided by Landlord
hereunder, to show the same to prospective purchasers of the Building, to make
such alterations, repairs, improvements or additions to the Premises, the
Building or other premises within the Building, as Landlord may deem necessary
or desirable, and to show the same to prospective tenants of the Premises.
Landlord shall use its best efforts to limit its entries into the Premises to no
more than two (2) times per month, by no more than five (5) people at a time,
and with at least twenty-four (24) hours notice. Landlord and its agent may
enter the Premises at all times and without advance notice for the purpose of
responding to an actual or apparent emergency. Landlord may for the purpose of
supplying scheduled janitorial services and evaluating janitorial services at
any time and from time to time enter the Premises by means of a master key
without liability to Tenant and without affecting this Lease. If, during the
last 60 days of the term hereof, Tenant shall have removed substantially all of
its property from the Premises, Landlord may immediately enter and alter,
renovate and redecorate the Premises without elimination or abatement of rent or
incurring liability to Tenant for any compensation.

     12. Mechanic's Liens: Tenant shall pay or cause to be paid all costs for
work done by or on behalf of Tenant or caused to be done by or on behalf of
Tenant on the Premises of a character which will or may result in liens against
Landlord's interest in the Premises, Building or Building Complex and Tenant
will keep the Premises, Building and Building Complex free and clear of all
mechanic's liens and other liens on account of work done for or on behalf of
Tenant or persons claiming under Tenant. Tenant hereby agrees to indemnify,
defend and save Landlord harmless of and from all liability, loss, damages,
costs or expenses, including attorneys' fees, incurred in connection with any
claims of any nature whatsoever for work performed for, or materials or supplies
furnished to Tenant, including lien claims of laborers, materialmen or others.
Should any such liens be filed or recorded against the Premises, Building or
Building Complex with respect to work done for or materials supplied to or on
behalf of Tenant or should any action affecting the title thereto be commenced,
Tenant shall cause such liens to be released of record within ten (10) days
after notice thereof. If Tenant desires to contest any such claim of lien,
Tenant shall nonetheless cause such lien to be released of record by the posting
of adequate security with a court of competent jurisdiction if provided by
applicable law or statute of the state where the Premises are located. If Tenant
shall be in default in paying any charge for which such a mechanic's lien or
suit to foreclose such a lien has been recorded or filed and shall not have
caused the lien to be released as aforesaid, Landlord may (but without being
required to do so) pay such lien or claim and any costs associated therewith,
and the amount so paid, together with interest at the Interest Rate and
reasonable attorneys' fees incurred in connection therewith, shall be
immediately due and payable from Tenant to Landlord as Additional Rent.

     13. Damage to Property, Injury to Persons:

         (a) Tenant, for itself and its legal representatives, successors and
assigns, as a material part of the consideration to be rendered to Landlord
under this Lease, hereby waives all claims of liability against Landlord.
Tenant, for itself and its legal representatives, successors and assigns, hereby
indemnifies and agrees to hold harmless Landlord, its agents, employees,
contractors, legal representatives, successors and assigns, from any and all
claims of liability for any injury or damage to any person or property
whatsoever occurring in, on or about the Premises or the Building Complex or any
part thereof, to the extent such injury or damage is caused by the negligence,
fault or omission of Tenant, its agents, contractors, employees, licensees or
invitees. Tenant further agrees to indemnify and to hold Landlord harmless from
and against any and all claims arising from any breach or default in the
performance of any obligation on Tenant's part to be performed under the terms
of this Lease, or arising from any act or negligence of Tenant, or any of its
agents, contractors, employees, licensees or invitees. Such indemnities shall
include by way of example, but not limitation, all costs, reasonable attorneys'
fees, expenses and liabilities incurred in or about any such claim, action or
proceeding.

                                       10

<PAGE>   16
         (b) Landlord shall not be liable to Tenant for any damage by or from
any act or negligence of any co-tenant or other occupant of the Building
Complex, or by any owner or occupant of adjoining or contiguous property.
Landlord shall not be liable for any injury or damage to persons or property
resulting in whole or in part from the criminal activities of others. To the
extent not covered by normal fire and extended coverage insurance, Tenant agrees
to pay for all damage to the Building Complex, as well as all damage to persons
or property of other tenants or occupants thereof, caused by the misuse,
neglect, act, omission or negligence of Tenant or any of its agents,
contractors, employees, licensees or invitees.

         (c) Neither Landlord nor its agents or employees shall be liable for
any damage to property entrusted to Landlord, its agents or employees, or
employees of the building manager, if any, nor for the loss or damage to any
property occurring by theft or otherwise, nor for any injury or damage to
persons or property resulting from fire, explosion, falling plaster, steam, gas,
electricity, water or rain which may leak from any part of the Building Complex
or from the pipes, appliances or plumbing works therein or from the roof, street
or subsurface or from any other place or resulting from dampness, or any other
cause whatsoever; provided, however, nothing contained herein shall be construed
to relieve Landlord from liability for any personal injury resulting from its
gross negligence. Neither Landlord nor its agents or employees shall be liable
for interference with the lights, view or other incorporeal hereditaments, nor
shall Landlord be liable for any latent defect in the Premises or in the
Building or Building Complex. Tenant shall give prompt notice to Landlord in
case of fire or accidents in or about the Premises or the Building or of defects
therein or in the fixtures or equipment located therein.

         (d) In case any claim, demand, action or proceeding is made or brought
against Landlord, its agents or employees, by reason of any obligation on
Tenant's part to be performed under the terms of this Lease, or arising from any
act or negligence of Tenant, its agents or employees, or which gives rise to
Tenant's obligation to indemnify Landlord, Tenant shall be responsible for all
costs and expenses, including but not limited to reasonable attorneys' fees
incurred in defending or prosecution of the same, as applicable.

     14. Insurance:

         (a) Landlord agrees to carry and maintain general public liability
insurance against claims for personal injury, including death and property
damage in or about the Building Complex (excluding Tenant's Property), such
insurance to be in such amounts as Landlord (or its mortgagees) may deem
appropriate. Such insurance may expressly exclude property paid for by tenants
or paid for by Landlord for which tenants have reimbursed Landlord located in,
or constituting a part of the Building or the Building Complex. Such insurance
shall afford coverage for damages resulting from (a) fire, (b) perils covered by
extended coverage insurance, and (c) explosion of steam and pressure boilers and
similar apparatus located in the Building or the Building Complex. Landlord may
carry such other additional insurance coverage as Landlord or Landlord's
mortgagee deems appropriate including coverage for loss of rents. All such
insurance shall be procured from a responsible insurance company or companies
authorized to do business in the State where the Premises are located.

         (b) Tenant shall, at its own cost, at all times during the term of this
Lease and any extensions hereof, procure and maintain insurance for hazard, fire
and extended coverage on Tenant's Property and the contents of the Premises in
an amount equal to full replacement cost thereof, and comprehensive general
liability insurance, including coverage for bodily injury, property damage,
personal injury (employee and contractual liability exclusions deleted),
products and completed operations, contractual liability, owner's protective
liability, host liquor legal liability and broad form property damage with the
following limits of liability: Two Million Dollars ($2,000,000.00) each
occurrence combined single limit for bodily injury, property damage and personal
injury; Two Million Dollars ($2,000,000.00) aggregate for bodily injury and
property damage for products and completed operations. All such insurance shall
be procured from a responsible insurance company or companies authorized to do
business in the State where the Premises are located, with general
policyholder's ratings of not less than "A" and a financial rating of not less
than "XI" in the most current available Best's Insurance Reports, and shall be
otherwise satisfactory to Landlord. All such policies shall name Landlord as an
additional insured, and shall provide that the same may not be canceled or
altered except upon thirty (30) days prior written notice to Landlord. All
insurance maintained by Tenant shall be

                                       11

<PAGE>   17
primary to any insurance provided by Landlord. If Tenant obtains any general
liability insurance policy on a claims-made basis, Tenant shall provide
continuous liability coverage for claims arising during the entire term of this
Lease, regardless of when such claims are made, either by obtaining an
endorsement providing for an unlimited extended reporting period in the event
such policy is canceled or not renewed for any reason whatsoever or by obtaining
new coverage with a retroactive date the same as or earlier than the expiration
date of the canceled or expired policy. Tenant shall provide certificate(s) of
such insurance to Landlord upon commencement of the Lease term and at least
thirty (30) days prior to any annual renewal date thereof and upon request from
time to time and such certificate(s) shall disclose that such insurance names
Landlord as an additional insured, in addition to the other requirements set
forth herein. The limits of such insurance shall not, under any circumstances,
limit the liability of Tenant hereunder.

         (c) Each party agrees to use its best efforts to include in each of its
policies insuring against loss, damage or destruction by fire or other casualty
a waiver of the insurer's right of subrogation against the other party, or if
such waiver should be unobtainable or unenforceable (i) an express agreement
that such policy shall not be invalidated if the insured waives the right of
recovery against any party responsible for a casualty covered by the policy
before the casualty; or (ii) any other form of permission for the release of the
other party. If such waiver, agreement or permission shall not be, or shall
cease to be, obtainable without additional charge or at all, the insured party
shall so notify the other party promptly after learning thereof. In such case,
if the other party shall so elect and shall pay the insurer's additional charge
therefor, such waiver, agreement or permission shall be included in the policy,
or the other party shall be named as an additional insured in the policy. Each
such policy which shall so name a party hereto as an additional insured shall
contain, if obtainable, agreements by the insurer that the policy will not be
canceled without at least thirty (30) days prior notice to both insureds and
that the act or omission of one insured will not invalidate the policy as to the
other insured. Any failure by either party, if named as an additional insured,
promptly to endorse to the order of the other party, without recourse, any
instrument for the payment of money under or with respect to the policy of which
the other party is the owner or original or primary insured, shall be deemed a
default under this Lease.

         (d) Each party hereby releases the other party with respect to any
claim (including a claim for negligence) which it might otherwise have against
the other party for loss, damage or destruction with respect to its property
(including the Building, Building Complex, the Premises and rental value or
business interruption) occurring during the term of this Lease to the extent to
which it is insured under a policy or policies containing a waiver of
subrogation or permission to release liability or naming the above party as an
additional insured as provided above.

         (e) Neither Landlord, the Building manager, if any, nor their
respective agents shall be liable for any damage to the property of Tenant or
others entrusted to employees of the Building, nor for the loss of or damage to
any property of Tenant by theft or otherwise and Tenant shall indemnify Landlord
of and from any loss or damages, costs or actions Landlord may suffer or incur
as a result of such loss or damage to Property.

     15. Damage or Destruction to Building:

         (a) In the event that the Premises or the Building are damaged by fire
or other insured casualty and the insurance proceeds have been made available
therefor by the holder or holders of any mortgages or deeds of trust covering
the Building, the damage shall be repaired by and at the expense of Landlord to
the extent of such insurance proceeds available therefor, provided such repairs
and restoration can, in Landlord's reasonable opinion, be made within two
hundred ten (210) days after the occurrence of such damage without the payment
of overtime or other premiums, and until such repairs and restoration are
completed, the Base Rent shall be abated in proportion to the part of the
Premises which is unusable by Tenant in the conduct of its business, as may be
reasonably determined by Landlord, (but there shall be no abatement of Base Rent
by reason of any portion of the Premises being unusable for a period equal to
one day or less). Landlord agrees to notify Tenant within forty-five (45) days
after such casualty if it estimates that it will be unable to repair and restore
the Premises within said two hundred ten (210) day period. Such notice shall set
forth the approximate length of time Landlord estimates will be required to
complete such repairs and restoration. Notwithstanding anything to the contrary
contained herein, if Landlord cannot or estimates it cannot make such repairs
and restoration within said two hundred ten (210) day period, then Tenant may,
by written notice

                                       12

<PAGE>   18
to Landlord cancel this Lease, provided such notice is given to Landlord within
fifteen (15) days after Landlord notifies Tenant of the estimated time for
completion of such repairs and restoration. Notwithstanding the preceding
sentence, Tenant may not cancel this Lease as hereinabove stated if the damage
to the Premises or the Building is in whole or in part the result of the act,
omission, fault or negligence of Tenant, its agents, contractors, employees,
licensees or invitees. Except as provided in this Paragraph 15, there shall be
no abatement of rent and no liability of Landlord by reason of any injury to or
interference with Tenant's business or property arising from the making of any
such repairs, alterations or improvements in or to the Building, Premises or
fixtures, appurtenances and equipment. Tenant understands that Landlord will not
carry insurance of any kind on Tenant's Property, including furniture and
furnishings, or on any fixtures or equipment removable by Tenant under the
provisions of this Lease, or any improvement installed in the Premises by or on
behalf of Tenant, and that Landlord shall not be obligated to repair any damage
thereto or replace the same.

         (b) In case the Building throughout shall be so injured or damaged,
whether by fire or otherwise (though the Premises may not be affected, or if
affected, can be repaired within said 210 days) that Landlord, within sixty (60)
days after the happening of such injury, shall decide not to reconstruct or
rebuild the Building, then notwithstanding anything contained herein to the
contrary, upon notice in writing to that effect given by Landlord to Tenant
within said sixty (60) days, Tenant shall pay the rent, properly apportioned up
to date of such casualty, this Lease shall terminate from the date of delivery
of said written notice, and both parties hereto shall be released and discharged
from all further obligations hereunder (except those obligations which expressly
survive termination of the Lease term).

     16. Condemnation:

         (a) If the whole of the Premises or so much thereof as to render the
balance unusable by Tenant for the proper conduct of its business shall be taken
under power of eminent domain or transferred under threat thereof, then this
Lease, at the option of either Landlord or Tenant exercised by either party
giving notice to the other of such election within thirty (30) days after such
conveyance or taking possession, whichever is earlier, shall forthwith cease and
terminate and the rent shall be duly apportioned as of the date of such taking
or conveyance. No award for any partial or entire taking shall be apportioned
and Tenant hereby assigns to Landlord any award which may be made in such taking
or condemnation, together with any and all rights of Tenant now or hereafter
arising in or to the same or any part thereof. Notwithstanding the foregoing,
Tenant shall be entitled to seek, directly from the condemning authority, an
award for its removable trade fixtures, equipment and personal property and
relocation expenses, if any, to the extent Landlord's award is not diminished.
In the event of a partial taking which does not result in a termination of this
Lease, Base Rent shall be reduced in proportion to the reduction in the size of
the Premises so taken and this Lease shall be modified accordingly. Promptly
after obtaining knowledge thereof, Landlord or Tenant, as the case may be, shall
notify the other of any pending or threatened condemnation or taking affecting
the Premises or the Building.

         (b) If all or any portion of the Premises shall be condemned or taken
for governmental occupancy for a limited period, this Lease shall not terminate
and Landlord shall be entitled to receive the entire amount of any such award or
payment thereof as damages, rent or otherwise. Tenant hereby assigns to Landlord
any award which may be made in such temporary taking, together with any and all
rights of Tenant now or hereafter arising in or to the same or any part thereof.
Tenant shall be entitled to receive an abatement of Base Rent in proportion to
the reduction in the size of the Premises so taken.

     17. Assignment and Subletting:

         (a) Tenant shall not permit any part of the Premises to be used or
occupied by any persons other than Tenant and its employees, nor shall Tenant
permit any part of the Premises to be used or occupied by any licensee or
concessionaire or permit any persons other than Tenant, its employees and
invitees, to be upon the Premises. Tenant shall not voluntarily, by operation of
law, or otherwise, assign, transfer or encumber this Lease or any interest
herein nor sublet or part with possession of all or any part of the Premises
(any and all of which shall

                                       13
<PAGE>   19
hereinafter be referred to as "Transfer") without Landlord's prior written
consent, which shall not be unreasonably withheld. Any Transfer without the
prior written consent of Landlord shall constitute a default hereunder and shall
be void ab initio and shall confer no rights upon any third party,
notwithstanding Landlord's acceptance of rent payments from any purported
transferee. Landlord's consent to any requested assignment of this Lease or
subletting of all or any part of the Premises shall be subject to the following
conditions:

            (1) such consent and resulting subletting or assignment shall not
relieve Tenant of its primary obligations hereunder, including the obligation
for payment of all rents due hereunder;

            (2) Landlord, at its option and from time to time, may collect the
rent from the subtenant or assignee, and apply the net amount collected to the
rent herein reserved, but no such collection shall be deemed an acceptance by
Landlord of the subtenant or assignee as the tenant hereof, or a release of
Tenant from further performance of covenants on the part of Tenant herein
contained;

            (3) any such subtenant or assignee shall be a company or other
entity of good repute, engaged in a business or profession compatible with and
in keeping with the then standards of the Building and financially capable of
performing its obligations with respect to the Premises;

            (4) such subtenant or assignee shall assume and agree to perform all
of Tenant's obligations under this Lease insofar as they pertain to the space so
sublet or assigned; and

            (5) Tenant is not in default of any term or condition of this Lease
at the time it requests Landlord's consent.

         (b) In the event of any Transfer of this Lease or all or any part of
the Premises by Tenant, Landlord in addition to any rights contained herein,
shall have the option, at its discretion, to collect and receive the excess of
rent due to Tenant from such sublessee or assignee over the Base Rent due
hereunder. Further, in the event of any Transfer of this Lease of all or any
part of the Premises by Tenant without the prior written consent of Landlord,
Landlord, in addition to any rights contained herein shall have the following
options, at its discretion:

            (1) To give Tenant written notice of Landlord's intention to
terminate this Lease on the date such notice is given or on any later date
specified therein, whereupon, on the date specified in such notice, Tenant's
right to possession of the Premises shall cease and this Lease shall thereupon
be terminated, except as to any uncompleted obligations of Tenant; or

            (2) To re-enter and take possession of the Premises or the part
thereof subject to such Transfer, and to enforce all rights of Tenant, and
receive and collect all rents and other payments due to Tenant, in accordance
with such sublet or assignment of the Premises, or any part thereof, as if
Landlord was the sublettor or assignor, and to do whatever Tenant is permitted
to do pursuant to the terms of such sublease or assignment.

         (c) At the time of making a request for Landlord's consent to a
Transfer and not less than thirty (30) days prior to the proposed effective date
thereof, Tenant shall provide to Landlord such information as Landlord, its
accountants and attorneys, shall reasonably require with respect to such
proposed Transfer, including but not limited to name and address of the proposed
transferee, description of business operations, financial information and
certificate of corporate authority and good standing or partnership certificate,
as applicable.

         (d) Consent of Landlord to a Transfer shall not relieve Tenant from
seeking consent to any subsequent Transfers.

         (e) Subletting or assignments by subtenants or assignees shall not be
permitted under any circumstances, nor shall Tenant be permitted to assign this
Lease or sublet all or any part of the Premises during any

                                       14
<PAGE>   20
period of time that all or any portion of the Base Rent is abated. Further, no
option to renew or extend the term of this Lease or to lease additional space,
if any, shall be exercisable by any subtenant or assignee.

         (f) All subleases or assignments shall be in writing and a copy thereof
provided to Landlord within ten (10) days of its effective date. All subleases
shall further contain an express provision that in the event of any default by
Tenant under this Lease and upon notice thereof to the subtenant from Landlord,
all rentals payable by the subtenant shall be paid directly to Landlord, for the
Tenant's account, until subsequent notice from Landlord that such default has
been cured. Notwithstanding the foregoing, receipt by Landlord of rent directly
from the subtenant shall not be considered a waiver of the default on the part
of Tenant, nor an acceptance of such subtenant.

         (g) Tenant shall have no right to sublet any portion of the Premises or
assign the Lease to any tenant in the Westmoor Business Park without Landlord's
prior written consent which may be withheld for any reason or no reason.
Furthermore, Tenant shall under no circumstances sublet space within the
Premises at a rental rate less than 80% of the then prevailing base rent within
the Building Complex.

         (h) No consent of Landlord shall be required for any assignment or
sublease to a successor of Tenant whether by merger, reorganization, stock sale,
sale of substantially all of Tenant's assets, or to an "Affiliate" of Tenant,
which includes any entity controlled by or under common control with the Tenant.

     18. Estoppel Certificate: Tenant further agrees at any time and from time
to time on or before five (5) days after written request by Landlord, to
execute, acknowledge and deliver to Landlord an estoppel certificate certifying
(to the extent it believes the same to be true) 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 modified, and stating the modifications), that
there have been no defaults thereunder by Landlord or Tenant (or if there have
been defaults, setting forth the nature thereof), the date to which the rent and
other charges have been paid, if any, that Tenant claims no present charge,
lien, claim or offset against rent, the rent is not prepaid for more than one
month in advance and such other matters as may be reasonably required by
Landlord, Landlord's mortgagee, or any potential purchaser of the Building, it
being intended that any such statement delivered pursuant to this Paragraph may
be relied upon by any prospective purchaser of all or any portion of Landlord's
interest herein, or a holder of any mortgage or deed of trust encumbering any
portion of the Building Complex. Tenant's failure to deliver such statement
within such time shall be a default under this Lease. Notwithstanding the
foregoing, in the event that Tenant does not execute the statement required by
this paragraph, Tenant hereby grants to Landlord a power of attorney coupled
with an interest to act as Tenant's attorney in fact for the purpose of
executing such statement or statements required by this Paragraph.

     19. Default:

         (a) The following events (herein referred to as an "event of default")
shall constitute a default by Tenant hereunder;

               (1) Tenant shall fail to pay within five (5) days of when due any
installment of Base Rent, Additional Rent or any other amounts payable
hereunder;

               (2) This Lease or the estate of Tenant hereunder shall be
transferred to or shall pass to or devolve upon any other person or party in
violation of the provisions of this Lease, except as permitted herein;

               (3) This Lease or the Premises or any part thereof shall be taken
upon execution or by other process of law directed against Tenant, or shall be
taken upon or subject to any attachment at the instance of any creditor or
claimant against Tenant, and said attachment shall not be discharged or disposed
of within fifteen (15) days after the levy thereof;

               (4) Tenant shall file a petition in bankruptcy or insolvency or
for reorganization or arrangement under the bankruptcy laws of the United States
or under any insolvency act of any state, or shall

                                       15

<PAGE>   21

voluntarily take advantage of any such law or act by answer or otherwise, or
shall be dissolved or shall make an assignment for the benefit of creditors;

               (5) Involuntary proceedings under any such bankruptcy law or
insolvency act or for the dissolution of Tenant shall be instituted against
Tenant, or a receiver or trustee shall be appointed of all or substantially all
of the property of Tenant, and such proceedings shall not be dismissed or such
receivership or trusteeship vacated within thirty (30) days after such
institution or appointment;

               (6) Tenant shall fail to take possession of the Premises within
thirty (30) days of the Commencement Date;

               (7) Tenant shall abandon or permanently vacate the Premises for
ten (10) consecutive days;

               (8) Tenant shall fail to perform any of the other agreements,
terms, covenants or conditions hereof on Tenant's part to be performed (other
than the obligation to pay rent or any other charges payable hereunder), and
such nonperformance shall continue for a period of fifteen (15) days after
notice thereof by Landlord to Tenant; provided, however, that if Tenant cannot
reasonably cure such nonperformance within fifteen (15) days, Tenant shall not
be in default if it commences cure within said fifteen (15) days and diligently
pursues the same to completion, with completion occurring in all instances
within sixty (60) days; and

               (9) Tenant shall fail to obtain a release of any mechanic's lien,
as required herein.

               (10) Tenant shall violate or breach any covenants or condition
contained in the Covenants or any rules or regulations of the Association
established pursuant thereto and shall not cure such violation or breach within
fifteen (15) days after notice thereof from the Association or from Landlord.

         (b) Upon the occurrence of an event of default, Landlord shall have the
right, at its election, then or at any time thereafter and while any such event
of default shall continue, either:

               (1) To give Tenant written notice of Landlord's intention to
terminate this Lease on the date such notice is given or on any later date
specified therein, whereupon, on the date specified in such notice, Tenant's
right to possession of the Premises shall cease and this Lease shall thereupon
be terminated; provided however, all of Tenant's obligations, including but not
limited to, the amount of Base Rent and other obligations reserved in this Lease
for the balance of the term hereof, shall immediately be accelerated and due and
payable.

               (2) To re-enter and take possession of the Premises or any part
thereof and repossess the same as Landlord's former estate and expel Tenant and
those claiming through or under Tenant, and remove the effects of both or
either, using such force for such purposes as may be reasonably necessary,
without being liable for prosecution thereof, without being deemed guilty of any
manner of trespass and without prejudice to any remedies for arrears of rent or
preceding breach of covenants or conditions. Should Landlord elect to re-enter
the Premises as provided in this Paragraph 19(b)(2) or should Landlord take
possession pursuant to legal proceedings or pursuant to any notice provided for
by law, Landlord may, from time to time, without terminating this Lease, relet
the Premises or any part thereof in Landlord's or Tenant's name, but for the
account of Tenant, for such term or terms (which may be greater or less than the
period which would otherwise have constituted the balance of the term of this
Lease) and on such conditions and upon such other terms (which may include
concessions of free rent and alteration and repair of the Premises) as Landlord,
in its discretion, may determine, and Landlord may collect and receive the rents
therefor. Landlord shall in no way be responsible or liable for any failure to
relet the Premises or any part thereof or for any failure to collect any rent
due upon such reletting. No such re-entry or taking possession of the Premises
by Landlord shall be construed as an election on Landlord's part to terminate
this Lease unless a written notice of such intention be given to Tenant. No
notice from Landlord hereunder or under a forcible entry and detainer statute or
similar law shall constitute an election by Landlord to terminate this Lease
unless such notice specifically so states.

                                       16

<PAGE>   22

Landlord reserves the right following any such re-entry and/or reletting, to
exercise its right to terminate this Lease by giving Tenant such written notice,
in which event, this Lease will terminate as specified in said notice.

         (c) In the event that Landlord does not elect to terminate this Lease
as permitted in Paragraph 19(b)(l) hereof, but on the contrary, elects to take
possession as provided in Paragraph 19(b)(2), Tenant shall pay to Landlord (i)
the rent and other sums as herein provided, which would be payable hereunder if
such repossession had not occurred, less (ii) the net proceeds, if any, of any
reletting of the Premises after deducting all Landlord's expenses in connection
with such reletting, including but without limitation, all repossession costs,
brokerage commissions, legal expenses, attorneys' fees, expenses of employees,
alteration and repair costs and expenses of preparation for such reletting. If,
in connection with any reletting, the new lease term extends beyond the existing
term, or the premises covered thereby include other premises not part of the
Premises, a fair apportionment of the rent received from such reletting and the
expenses incurred in connection therewith as provided aforesaid will be made in
determining the net proceeds from such reletting. Tenant shall pay such rent and
other sums to Landlord monthly on the days on which the rent would have been
payable hereunder if possession had not been retaken.

         (d) In the event this Lease is terminated, Landlord shall be entitled
to recover forthwith against Tenant as damages for loss of the bargain and not
as a penalty, an aggregate sum which, at the time of such termination of this
Lease, represents the excess, if any, of the aggregate of the rent and all other
sums payable by Tenant hereunder that would have accrued for the balance of the
term over the aggregate rental value of the Premises (such rental value to be
computed on the basis of a tenant paying not only a rent to Landlord for the use
and occupation of the Premises, but also such other charges as are required to
be paid by Tenant under the terms of this Lease) for the balance of such term,
both discounted to present worth at the rate of eight percent (8%) per annum.
Alternatively, at Landlord's option, Tenant shall remain liable to Landlord for
damages in an amount equal to the rent and other sums arising under the Lease
for the balance of the term had the Lease not been terminated, less the net
proceeds, if any, from any subsequent reletting, after deducting all expenses
associated therewith and as enumerated above. Landlord shall be entitled to
receipt of such amounts from Tenant monthly on the days on which such sums would
have otherwise been payable.

         (e) Suit or suits for the recovery of the amounts and damages set forth
above may be brought by Landlord, from time to time, at Landlord's election and
nothing herein shall be deemed to require Landlord to await the date whereon
this Lease or the term hereof would have expired had there been no such default
by Tenant or no such termination, as the case may be.

         (f) After an event of default by Tenant, Landlord may sue for or
otherwise collect all rents, issues and profits payable under all subleases on
the Premises, including those past due and unpaid.

         (g) After an event of default by Tenant, Landlord may without
terminating this Lease, enter upon the Premises, with force if necessary,
without being liable for prosecution of any claim for damages, without being
deemed guilty of any manner of trespass and without prejudice to any other
remedies, and do whatever Tenant is obligated to do under the terms of this
Lease. Tenant agrees to reimburse Landlord on demand for any expenses which
Landlord may incur in effecting compliance with the Tenant's obligations under
this Lease; further, Tenant agrees that Landlord shall not be liable for any
damages resulting to Tenant from effecting compliance with Tenant's obligations
under this subparagraph caused by the negligence of Landlord or otherwise.

         (h) No failure by Landlord to insist upon the strict performance of any
agreement, term, covenant or condition hereof or to exercise any right or remedy
consequent upon a breach thereof, and no acceptance of full or partial rent
during the continuance of any such breach, shall constitute a waiver of any such
breach of such agreement, term, covenant or condition. No agreement, term,
covenant or condition hereof to be performed or complied with by Tenant, and no
breach thereof, shall be waived, altered or modified except by written
instrument executed by Landlord. No waiver of any breach shall affect or alter
this Lease, but each and every agreement, term, covenant and condition hereof
shall continue in full force and effect with respect to any other then existing
or subsequent breach thereof. Notwithstanding any unilateral termination of this
Lease, this Lease shall continue in force

                                       17

<PAGE>   23

and effect as to any provisions hereof which require observance or performance
of Landlord or Tenant subsequent to termination.

         (i) Nothing contained in this Paragraph shall limit or prejudice the
right of Landlord to prove and obtain as liquidated damages in any bankruptcy,
insolvency, receivership, reorganization or dissolution proceeding, an amount
equal to the maximum allowed by any statute or rule of law governing such
proceeding and in effect at the time when such damages are to be proved, whether
or not such amount be greater, equal to or less than the amounts recoverable,
either as damages or rent, referred to in any of the preceding provisions of
this Paragraph.

         (j) Any rents or other amounts owing to Landlord hereunder which are
not paid within five (5) days of the date they are due, shall thereafter bear
interest from the due date at the rate of eighteen percent (18%) per annum
("Interest Rate") until paid. Similarly, any amounts paid by Landlord to cure
any default of Tenant or to perform any obligation of Tenant, shall, if not
repaid by the Tenant within five (5) days of demand by Landlord, thereafter bear
interest from the date paid by Landlord at the Interest Rate until paid. In
addition to the foregoing, Tenant shall pay to Landlord whenever any Base Rent,
Additional Rent or any other sums due hereunder remain unpaid more than five (5)
days after the due date thereof, an administrative charge to compensate Landlord
for the costs and expenses associated with handling a delinquent account equal
to ten percent (10%) of the amount due. Further, in the event of default by
Tenant, in addition to all other rights and remedies, Landlord shall be entitled
to receive from Tenant all sums, the payment of which may previously have been
waived or abated by Landlord, or which may have been paid by Landlord pursuant
to any agreement to grant Tenant a rental abatement or other monetary inducement
or concession, including but not limited to any tenant finish allowance or
moving allowance, together with interest thereon from the date or dates such
amounts were paid by Landlord or would have been due from Tenant but for the
abatement, at the Interest Rate, until paid; it being understood and agreed that
such concession or abatement was made on the condition and basis that Tenant
fully perform all obligations and covenants under the Lease for the entire term.
Not withstanding the above, said ten Percent (10%) penalty shall be waived by
Landlord for the first two (2) occurrences during any calendar year provided the
Payment is received on or before the tenth (10th) day of the month.

         (k) Each right and remedy provided for in this Lease shall be
cumulative and shall be in addition to every other right or remedy provided for
in this Lease now or hereafter existing at law or in equity or by statute or
otherwise, including, but not limited to, suits for injunctive or declaratory
relief and specific performance. The exercise or commencement of the exercise by
Landlord of any one or more of the rights or remedies provided for in this Lease
now or hereafter existing at law or in equity or by statute or otherwise shall
not preclude the simultaneous or subsequent exercise by Landlord of any or all
other rights or remedies provided for in this Lease, or now or hereafter
existing at law or in equity or by statute or otherwise. All costs incurred by
Landlord in connection with collecting any amounts and damages owing by Tenant
pursuant to the provisions of this Lease or to enforce any provision of this
Lease, including by way of example, but not limitation, reasonable attorneys'
fees from the date any such matter is turned over to an attorney, shall also be
recoverable by Landlord from Tenant. LANDLORD AND TENANT AGREE THAT ANY ACTION
OR PROCEEDING ARISING OUT OF THIS LEASE SHALL BE HEARD BY A COURT SITTING
WITHOUT A JURY AND THUS HEREBY WAIVE ALL RIGHTS TO A TRIAL BY JURY.

     20. Completion of Premises:

         (a) Landlord has agreed to complete the Premises as more fully set
forth in a work letter (the "Work Letter") attached hereto and incorporated
herein as Exhibit D. Other than as set forth in the Work Letter, Landlord shall
have no obligation for the completion of the Premises, and Tenant shall accept
the Premises in its "as is" condition on the Commencement Date. Landlord shall
not have any obligation for the repair or replacement of any portions of the
interior of the Premises, including but not limited to carpeting, draperies,
window coverings, wallcoverings or painting, which are damaged or wear out
during the term hereof, regardless of the cause therefor, except as may
otherwise be specifically set forth in this Lease. If the Premises are not Ready
for Occupancy (as hereafter defined) on the Commencement Date, unless such delay
is caused by Tenant, its agents or employees, the

                                       18

<PAGE>   24
rental obligations hereunder shall not commence until the Premises are Ready for
Occupancy, whereupon, this Lease and all covenants, conditions and terms hereof
shall be in full force and effect; and the Termination Date hereof shall be
postponed as set forth in paragraph 2(b). The postponement of the rent and term
herein provided for such period shall be in full settlement for all claims which
Tenant might have by reason of the Premises not being Ready for Occupancy on the
Commencement Date. If Tenant wishes to take possession of all or any part of the
Premises prior to the date the Premises are Ready for Occupancy, it must first
secure the prior written consent of Landlord and such occupancy shall in no way
hinder, delay or interfere with Landlord's work in completion of the Premises,
and in such event, all terms and provisions of this Lease, including the
obligation to pay rent at a rate equal to the monthly rate provided in Paragraph
3 (prorated accordingly) shall apply. "Ready for Occupancy" as that term is used
herein shall mean the date when all major construction aspects of the Premises
and any remodeling work to be performed by Landlord to the extent agreed to in
the Work Letter are completed although minor items are not completed (including
but not limited to, touch-up plastering or repainting which does not
unreasonably interfere with Tenant's ability to carry on its business in the
Premises). The certificate of the architect (or other representative of
Landlord) in charge of supervising the completion or remodeling of the Premises
shall control conclusively the date upon which the Premises are Ready for
Occupancy. If Landlord is delayed in delivering the Premises to Tenant because
the same are not Ready for Occupancy or due to the failure of a prior occupant
to vacate the same, then the rent and term shall be postponed as hereinabove set
forth, and such postponement shall be in full settlement of all claims which
Tenant may otherwise have by reason of the delay of delivery.

         (b) Landlord, at its sole option, may allow Tenant to enter into the
Premises for the purpose of installing furniture, fixtures and equipment and
other leasehold improvements, including, but not limited to, wall and floor
coverings, millwork and draperies, subject to the terms of the Work Letter prior
to the Commencement Date at its sole risk and with no obligation to pay rent
provided that such entry and work do not unreasonably interfere in any way with
the performance of Landlord's work or other workers in and about the Building.
At any time during such period of early entry, if Landlord notifies Tenant that
Tenant's entry or work is interfering with or delaying the performance of work
to be performed by Landlord or other workers in and about the Building, or
causing any disruption whatsoever, Tenant shall forthwith discontinue any
further work and shall vacate the Premises, and shall cause its workmen or
contractors to remove therefrom, any equipment, materials or installations which
are the subject of Landlord's notice.

     21. Removal of Tenant's Property: All movable furniture and personal
effects of Tenant not removed from the Premises upon the vacation or abandonment
thereof or upon the termination of this Lease for any cause whatsoever shall
conclusively be deemed to have been abandoned and may be appropriated, sold,
stored, destroyed or otherwise disposed of by Landlord without notice to Tenant
and without obligation to account therefor, and Tenant shall reimburse Landlord
for all expenses incurred in connection with the disposition of such property.

     22. Holding Over: Should Tenant, with Landlord's written consent, hold over
after the termination of this Lease, Tenant shall be deemed a tenant at will.
During such holdover period, Tenant shall be liable for all damages incurred by
Landlord as a result of Tenant's withholding of the Premises. Should Tenant
holdover after the termination of this Lease, with Landlord's consent, Tenant
shall become a tenant from month to month only upon each and all of the terms
herein provided as may be applicable to such month to month tenancy and any such
holding over shall not constitute an extension of this Lease. During such
holding over, Tenant shall pay monthly rent equal to one hundred fifty percent
(150%) of the last monthly rental rate and the other monetary charges as
provided herein. Such tenancy shall continue until terminated by Landlord, as
provided by law, or until Tenant shall have given to Landlord at least thirty
(30) days written notice prior to the last day of the calendar month intended as
the date of termination of such month to month tenancy.

     23. Parking and Common Areas: Tenant shall have the right to utilize five
(5) parking spaces for every one thousand (1,000) usable square feet of the
Premises, in the parking area adjacent to the Building during the Primary Lease
Term. Landlord shall have the right, without obligation, and from time to time,
to change the number, size, location, shape and arrangement of parking areas and
other common areas, create designated or reserved spaces, restrict parking of
tenants or their guests to designated areas, designate loading or handicap
loading areas and to,

                                       19

<PAGE>   25

change the level or grade of parking. Except as otherwise specifically provided
herein, all access roads, courtyards and other areas, facilities or improvements
furnished by Landlord are for the general and nonexclusive use in common of all
tenants of the Building, and those persons invited upon the land upon which the
Building is situated and shall be subject to the exclusive control and
management of Landlord, and Landlord shall have the right, without obligation to
establish, modify and enforce such rules and regulations, which the Landlord may
deem reasonable and/or necessary. Unless as otherwise provided, Tenant's use of
the parking area, as herein set forth, shall be in common with other tenants of
the Building and any other parties permitted by Landlord to use the parking
area. The parking rights herein granted shall not be deemed a lease but shall be
construed as a license granted by Landlord to Tenant for the term of this Lease.
Landlord shall not have the obligation to monitor the utilization of the parking
areas or to verify correct utilization of parking facilities by tenants of the
Building.

     24. Surrender and Notice: Upon the expiration or earlier termination of
this Lease, Tenant shall promptly quit and surrender to Landlord the Premises
broom clean, in good order and condition, ordinary wear and tear and loss by
fire or other casualty excepted, and Tenant shall remove all of its movable
furniture and other effects and such alterations, additions and improvements as
Landlord shall require Tenant to remove pursuant to Paragraph 10 hereof. In the
event Tenant fails to so vacate the Premises on a timely basis as required,
Tenant shall be responsible to Landlord for all costs and damages, including but
not limited to any amounts required to be paid to third parties who were to have
occupied the Premises, incurred by Landlord as a result of such failure, plus
interest thereon at the Interest Rate on all amounts not paid by Tenant within
five (5) days of demand, until paid in full.

     25. Acceptance of Premises by Tenant: Taking possession of the Premises by
Tenant shall be conclusive evidence as against Tenant that the Premises were in
the condition agreed upon between Landlord and Tenant, and acknowledgment of
satisfactory completion of the fix-up work which Landlord has agreed in writing
to perform, except as otherwise set forth herein.

     26. Subordination and Attornment:

         (a) This Lease, and all rights of Tenant hereunder, are and shall be
subject and subordinate in all respects to all present and future ground leases,
overriding leases and underlying leases and/or grants of term of the real
property and/or the Building or the Building Complex now or hereafter existing
and to all deeds of trust, mortgages and building loan agreements, including
leasehold mortgages and building loan agreements, which may now or hereafter
affect the Building or the Building Complex or any of such leases, whether or
not such deeds of trust or mortgages shall also cover other lands or buildings,
to each and every advance made or hereafter to be made under such deeds of trust
or mortgages, and to all renewals, modifications, replacements and extension of
such leases, deeds of trust and mortgages. The provisions of this Paragraph
shall be self-operative and no further instrument of subordination shall be
required. However, in confirmation of such subordination, Tenant shall promptly
execute and deliver to Landlord (or such other party so designated by Landlord)
at Tenant's own cost and expense, within five (5) days after request from
Landlord an instrument, in recordable form if required, that Landlord, the
lessor of any such lease or the holder of any such deed of trust or mortgage or
any of their respective successors in interest or assigns may request evidencing
such subordination. Failure by Tenant to comply with the requirements of this
Paragraph shall be a default hereunder. Notwithstanding the foregoing, in the
event that Tenant does not execute such documents as may be required to confirm
the subordination set forth in this Paragraph, Tenant hereby grants to Landlord
a power of attorney coupled with an interest to act as Tenant's attorney in fact
for the purposes of executing whatever documents are necessary to evidence such
subordination. The leases to which this Lease is, at the time referred to,
subject and subordinate pursuant to this Paragraph are hereinafter sometimes
called "superior leases" and the deeds of trust or mortgages to which this Lease
is, at the time referred to, subject and subordinate are hereinafter sometimes
called "superior deeds of trust" or "superior mortgages". The lessor of a
superior lease or the beneficiary of a superior deed of trust or superior
mortgage or their successors in interest or assigns are hereinafter sometimes
collectively referred to as a "superior party". Notwithstanding the foregoing,
upon Tenant's request, Landlord agrees to request such superior party grant to
Tenant a non-disturbance agreement in the form then being used by such superior
party for such purposes, providing that Tenant, notwithstanding a default by
Landlord, shall be entitled to remain in

                                       20

<PAGE>   26
possession of the Premises in accordance with the terms of this Lease for so
long as Tenant shall not be in default of any term, condition or covenant of
this Lease. Further, Tenant shall attorn to such superior party.

         (b) Tenant shall take no steps to terminate this Lease, without giving
written notice to such superior party, and a reasonable opportunity to cure
(without such superior party being obligated to cure), any default on the part
of Landlord under this Lease.

         (c) If, in connection with the procurement, continuation or renewal of
any financing for which the Building or the Building Complex or of which the
interest of the lessee therein under a superior lease represents collateral in
whole or in part, a lender shall request reasonable modifications of this Lease
as a condition of such financing, Tenant will not unreasonably withhold its
consent thereto provided that such modifications do not increase the obligations
of Tenant under this Lease or adversely affect any rights of Tenant or decrease
the obligations of Landlord under this Lease.

     27. Payments After Termination: No payments of money by Tenant to Landlord
after the termination of this Lease, in any manner, or after giving of any
notice (other than a demand for payment of money) by Landlord to Tenant, shall
reinstate, continue or extend the term of this Lease or affect any notice given
to Tenant prior to the payment of such money, it being agreed that after the
service of notice of the commencement of a suit or other final judgment granting
Landlord possession of the Premises, Landlord may receive and collect any sums
of rent due, or any other sums of money due under the terms of this Lease or
otherwise exercise its rights and remedies hereunder. The payment of such sums
of money, whether as rent or otherwise, shall not waive said notice or in any
manner affect any pending suit or judgment theretofore obtained.

     28. Authorities for Action and Notice:

         (a) Except as otherwise provided herein, Landlord may, for any matter
pertaining to this Lease, act by and through its Building manager or any other
person designated in writing from time to time.

         (b) All notices or demands required or permitted to be sent by one
party to the other hereunder as required by law shall be in writing and shall be
deemed to have been validly given or served by delivery of same in person to the
addressee by facsimile, or by depositing same with Fed Ex or other carrier,
service for next business day delivery, or in the United States mail, postage
prepaid, registered or certified mail return receipt requested, addressed as

shall commence to run from the next business day after deposit with Fed Ex or
other courier service or the date on the return receipt of the notice, demand or
request reflecting the date of delivery or rejection of the same by the
addressee thereof in the case of a deposit in the United States mail. Rejection
or other refusal to accept or the inability to deliver because of changed

notice, demand or request sent. By giving to the other party hereto at least 30
days' written notice thereof in accordance with the provisions hereof, the
parties hereto shall have the right from time to time to change their respective
addresses.

     29. Liability of Landlord: Landlord's liability under this Lease shall be
limited to Landlord's estate and interest in the Building (or to the proceeds
thereof) and no other property or other assets of Landlord or its partners (if
Landlord is a partnership), agents, employees, legal representatives, successors
or assigns, shall be subject to levy, execution or other enforcement procedure
for the satisfaction of Tenant's remedies under or with respect to this Lease,
the relationship of Landlord and Tenant hereunder or Tenant's use and occupancy
of the Premises. Nothing contained in this Paragraph shall be construed to
permit Tenant to offset against rents due a successor landlord, a judgment (or
other judicial process) requiring the payment of money by reason of any default
of a prior landlord, except as otherwise specifically set forth herein.

     30. Brokerage: Landlord is represented by the Frederick Ross Company
("Landlord Broker") Tenant represents and warrants that it has dealt only with
Prime West Real Estate Services (the "Tenant Broker") in the negotiation of this
Lease. Landlord shall make payment of the brokerage fee due to the Landlord
Broker and Tenant Broker (through Landlord Broker's Agreement) pursuant to and
in accordance with Landlord's separate agreement with the Landlord Broker.
Tenant hereby agrees to indemnify and hold the Landlord harmless of and from any
and all loss, costs, damages or expenses (including, without limitation, all
attorneys' fees and disbursements) by reason of any claim of or liability to any
other broker or person claiming through Tenant and arising out of or in
connection with the negotiation, execution and delivery of this Lease.
Additionally, Tenant acknowledges and agrees that Landlord shall have no
obligation for payment of any brokerage fee or similar compensation to any
person with whom Tenant has dealt or may in the future deal with respect to
leasing of any additional or expansion space in the Building or renewals or
extensions of this Lease. In the event any claim shall be made against Landlord
by any other broker who shall claim to have negotiated this Lease on behalf of
Tenant or to have introduced Tenant to the Building or to Landlord, Tenant shall
be liable for payment of all reasonable attorneys' fees, costs and expenses
incurred by Landlord in defending against the same, and in the event such broker
shall be successful in any such action, Tenant shall, in addition, make payment
to such Broker.

     31. Taxes:

         (a) Tenant shall be liable for and shall pay at least ten (10) days
before delinquency and Tenant hereby agrees to indemnify and hold Landlord
harmless from and against any liability in connection with, all taxes levied
against any personal property, fixtures, machinery, equipment, apparatus,
systems and appurtenances placed by or on behalf of Tenant in or about or
utilized by Tenant in, upon or in connection with the Premises ("Equipment
Taxes"). If any Equipment Taxes are levied against Landlord or Landlord's
property or if the assessed value of Landlord's property is increased by the
inclusion therein of a value placed upon such personal property, fixtures,
machinery, equipment, apparatus, systems or appurtenances of Tenant, and if
Landlord, after written notice to Tenant, pays the Equipment Taxes or taxes
based upon such an increased assessment (which Landlord shall have the right to
do regardless of the validity of such levy, but under proper protest if
requested by Tenant prior to such payment and if payment under protest is
permissible), Tenant shall pay to Landlord upon demand, as Additional Rent
hereunder, the taxes so levied against Landlord or the proportion of such taxes
resulting from such increase in the assessment; provided, however, that in any
such event, Tenant shall have the right, on behalf of Landlord and with
Landlord's full cooperation, but at no cost to Landlord, to bring suit in any
court of competent jurisdiction to recover the amount of any such tax so paid
under protest, and any amount so recovered shall belong to Tenant (provided
Tenant has previously paid such amount to Landlord). Notwithstanding the
foregoing to the contrary, Tenant shall cooperate with Landlord to the extent
reasonably necessary to cause the fixtures, furnishings, equipment and other
personal property to be assessed and billed separately from the real property of
which the Premises form a part, and Landlord shall use reasonable efforts to
treat all other Tenants on the same basis.

                                       22

<PAGE>   28
         (b) Tenant shall pay to Landlord, as Additional Rent, any excise,
sales, privilege or other tax, assessment or other charge (other than income or
franchise taxes) imposed, assessed or levied by any governmental or
quasi-governmental authority or agency upon Landlord on account of this Lease,
the rent or other payments made by Tenant hereunder, any other benefit received
by Landlord hereunder, Landlord's business as a lessor hereunder, or otherwise
in respect of or as a result of the agreement or relationship of Landlord and
Tenant hereunder.

     32. Substitution of Premises: Notwithstanding anything herein to the
contrary, Landlord shall have the right at any time and from to time to time to
substitute other premises located within the Building for the Premises subject
to the same terms and conditions set forth herein; provided, however, that the
substituted Premises shall contain at least as much square footage as the
originally leased Premises without any increase in the then rental rate. In
connection therewith, Landlord agrees to pay all reasonable moving expenses of
Tenant and of Tenant's permitted sub-lessees, including the reasonable
replacement of Tenant improvements. Tenant shall be required to move into such
substituted premises within 30 days of notice from Landlord of its exercise of
this right.

     33. Rights Reserved to Landlord:

         (a) All portions of the Building are reserved to Landlord except the
Premises and the inside surfaces of all walls, windows and doors bounding in the
Premises, but including exterior building walls, core corridor walls and doors
and any core corridor entrance. Landlord also reserves any space in or adjacent
to the Premises used for shafts, stacks, pipes, conduits, fan rooms, ducts,
electric or other utilities, sinks or other building facilities, and the use
thereof, as well as the right to access thereto through the Premises for the
purposes of operation, maintenance and repair, upon written notice of not less
than twenty-four (24) hours, except in the event of emergencies or apparent
emergencies, when no prior notice shall be required.

         (b) Landlord shall have the following rights without liability to
Tenant for damage or injury to property, person or business (all claims for
damage being hereby waived and released), and without effecting an eviction or
disturbance of Tenant's use or possession of the Premises or giving rise to any
claim for setoffs or abatement of rent:

             (1) To enter the Premises as more fully provided in this Lease.

             (2) To install and maintain signs on the exterior and interior of
the Building, except within the Premises, provided the signs do not block either
completely or partially the exterior windows of the Premises.

             (3) To have pass keys to the Premises.

             (4) To have access to all mail chutes according to the rules of the

the Building or any adjacent or nearby building, land, street or alley.

             (6) To grant to anyone the exclusive right to conduct any business
or render any service in the Building, provided such exclusive right shall not
operate to exclude Tenant from the use expressly permitted by this Lease.

             (7) To increase the size or alter the configuration of the Common
Area.

     34. Force Majeure Clause: Wherever there is provided in this Lease a time
limitation for performance by Landlord of any obligation, including but not
limited to obligations related to construction, repair, maintenance or service,
the time provided for shall be extended for as long as and to the extent that
delay in compliance with such limitation is due to an act of God, governmental
control or other factors beyond the reasonable control of Landlord.

                                       23

<PAGE>   29
     35. Signage:

         (a) No sign, advertisement or notice shall be inscribed, painted or
affixed on any part of the inside or outside of the Building unless of such
color, size and style and in such place upon or in the Building as shall be
first designated by Landlord, but there shall be no obligation or duty on
Landlord to allow any sign, advertisement or notice to be inscribed, painted or
affixed on any part of the inside or outside of the Building. A directory in a
conspicuous place in the Building lobby area, with the Tenant's name along with
the names of the other tenants in the Building, shall be provided by Landlord on
a one time basis. Any necessary revision to such directory shall be made by
Landlord, at Tenant's expense, within a reasonable time after written notice
from Tenant of the change making the revision necessary. Landlord shall have the
right to remove all nonpermitted signs without notice to Tenant and at the
expense of Tenant.

         (b) Tenant shall only be permitted to install building standard signs
and logos, subject to Landlord's prior written consent and criteria as to size,
design, materials and location.

     36. Attorneys' Fees: In the event of any dispute hereunder, or any default
in the performance of any term or condition of this Lease, the prevailing party
shall be entitled to recover all costs and expenses associated therewith,
including reasonable attorneys' fees.

     37. Hazardous Materials:

         (a) Tenant shall not cause or permit any Hazardous Material to be
brought upon, kept, or used in or about the Premises by Tenant, its agents,
employees, contractors, licensees or invitees, without the prior written consent
of Landlord (which Landlord shall not unreasonably withhold as long as Tenant
demonstrates to Landlord's reasonable satisfaction that such Hazardous Material
is necessary or useful to Tenant's business and will be used, kept and stored in
a manner that complies with all laws regulating any such Hazardous Material so
brought upon or used or kept in or about the Premises). If Tenant breaches the
obligations stated in the preceding sentence, or if the presence of Hazardous
Material on the Premises caused or permitted by Tenant results in
contamination of the Premises or Building Complex, or any part thereof, or if
contamination of the Premises or Building Complex by Hazardous Material
otherwise occurs for which Tenant is legally liable to Landlord for damage
resulting therefrom, then Tenant shall indemnify, defend and hold Landlord, its
agents, employees, legal representatives, successors and assigns, harmless from
any and all claims, judgments, damages, penalties, fines, costs, liabilities, or
losses (including, without limitation, diminution in value of the Premises and
Building Complex, damages for the loss or restriction on use of any rentable or
usable space or of any amenity of the Premises or Building Complex, damages
arising from any adverse impact on marketing of space in the Building, and sums
paid in settlement of claims, attorneys' fees, consultant fees and expert fees)
which arise during or after the Lease term as a result of such contamination.
This indemnification of Landlord by Tenant includes, without limitation, costs
incurred in connection with any investigation of site conditions or any cleanup,
remedial, removal or restoration work required by any federal, state, or local
governmental agency or political subdivision because of Hazardous Material
present in or about the Building Complex or the soil or ground water on or under
the Building Complex. Without limiting the foregoing, if the presence of any
Hazardous Material on or about the Building Complex caused or permitted by
Tenant results in any contamination of any portion thereof, Tenant shall
promptly take all actions at its sole expense as are necessary to return the
Building Complex to the condition existing prior to the introduction of any such
Hazardous Material, subject to obtaining Landlord's prior written consent to the
actions to be taken by Tenant. Landlord may properly require its consent to the
selection of the contractors and other experts involved in the inspection,
testing and removal or abatement activities, the scope of activities to be
performed, the manner and method for performance of such activities, and such
other matters as may be required or requested by Landlord for the safety of and
continued use of the Building Complex and all occupants thereof. The obligations
and liabilities of Tenant herein shall survive expiration or termination of this
Lease.

         (b) "Hazardous Material", as used in this Lease, shall be construed in
its broadest sense and shall include asbestos, other asbestotic material (which
is currently or may be designated in the future as a Hazardous

                                       24

<PAGE>   30
Material), any petroleum base products, pesticides, paints and solvents,
polychlorinated biphenyl, lead, cyanide, DDT, acids, ammonium compounds and
other chemical products (excluding commercially used cleaning materials in
ordinary quantities) and any substance or material if defined or designated as a
hazardous or toxic substance, or other similar term, by any federal, state or
local law, statute, regulation, or ordinance affecting the Building Complex or
Premises presently in effect or that may be promulgated in the future, as such
statutes, regulations and ordinances may be amended from time to time.

     38. Americans with Disabilities Act.

         (a) Landlord shall, subject to reimbursement as part of the Building's
Operating Expenses, be responsible for any alterations, modifications or
improvements to the Common Areas which are required under Title III of the
Americans With Disabilities Act ("ADA"). Not included as part of the Building's
Operating Expenses shall be any alterations or improvements made to another
tenant's premises in the Building.

         (b) Tenant shall, at Tenant's sole cost and expense, be responsible for
any alterations, modifications or improvements to the Premises, and the
acquisition of any auxiliary aids, required under the ADA, including all
alterations, modifications or improvements required: (1) as a result of Tenant
(or any subtenant, assignee or concessionaire) being a Public Accommodation (as
defined in the ADA); (2) as a result of the Premises being a Commercial Facility
(as defined in the ADA); (3) as a result of any leasehold improvements made to
the Premises by, or on behalf of, Tenant or any subtenant, assignee or
concessionaire (whether or not Landlord's consent to such leasehold improvements
was obtained); or (4) as a result of the employment by Tenant (or any subtenant,
assignee or concessionaire) of any individual with a disability.

         (c) With respect to the use restrictions set forth in Paragraph 6 of
this Lease, and the restrictions on assignments and subletting set forth in
Paragraph 17 of this Lease, it is hereby specifically understood and agreed that
Landlord shall have no obligation to consent to, or permit, a use of the
Premises, or an assignment of the Lease or a sublease of the Premises
(collectively herein a "Use Change") if such Use Change would require the making
of any alterations, modifications or improvements to the Premises or the Common
Areas, or the acquisition of any auxiliary aids, required under the ADA, unless
Tenant performs all such acts and satisfies Landlord's requirements for
financial responsibility for the costs of such compliance (which may include, by
way of example, posting of a completion bond, or establishment of an escrow
account).

         (d) With respect to the Leasehold Improvements (as described in the
Work Letter Agreement), Tenant shall be responsible for compliance with the ADA
in the design and layout of the Leasehold Improvements and Landlord shall have
no responsibility therefore.

     39. Bankruptcy or Insolvency. If the Tenant becomes a debtor under Chapter
7 of the United States Bankruptcy Code, or in the event that a petition for
reorganization or adjustment of debts is filed concerning the Tenant under
Chapter 11 or Chapter 13 of the Bankruptcy Code, or a proceeding filed under
Chapter 7 is transferred to Chapter 11 or 13, the Trustee or the Tenant, as
Debtor-in-Possession, shall be deemed to have rejected this Lease. No election
by the Trustee or Debtor-in-Possession to assume this Lease shall be effective
unless each of the following conditions, which Landlord and Tenant hereby
acknowledge to be commercially reasonable in the context of a bankruptcy
proceeding, has been satisfied, and the Landlord has so acknowledged in writing:

         (a) The Trustee or Debtor-in-Possession has cured, or has provided the
Landlord "adequate assurance" (as hereinafter defined) that from the date of
such assumption, the Trustee or Debtor-In-Possession will promptly cure all
monetary and non-monetary defaults under this Lease.

         (b) The Trustee or Debtor-in-Possession has compensated, or has
provided to the Landlord adequate assurance that within ten (10) days of the
date of assumption, the Landlord will be compensated, for any pecuniary loss
incurred by the Landlord arising from default of the Tenant, the Trustee or the
Debtor-in-Possession as recited in the Landlord's written statement of pecuniary
loss sent to the Trustee or Debtor-in-Possession.

                                       25
<PAGE>   31

         (c) The Trustee or Debtor-in-Possession has provided the Landlord with
adequate assurance of future performance of each of the Tenant's, the Trustee's,
or Debtor-in-Possession's obligations under this Lease; provided, however, that:

             (1) The Trustee or Debtor-in-Possession shall also deposit with the
Landlord, as security for the timely payment of rent and other sums due
hereunder, an amount equal to three months Base Rent, Additional Rent and other
monetary charges accruing under this Lease; and

             (2) The obligations imposed upon the Trustee or
Debtor-in-Possession shall continue with respect to the Tenant or any assignee
of this Lease after the completion of the bankruptcy proceedings.

         (d) For purposes of this Paragraph, Landlord and Tenant acknowledge
that, in the context of the bankruptcy proceeding of the Tenant, at a minimum,
"adequate assurance" shall mean:

             (1) The Trustee or Debtor-in-Possession will continue to have
sufficient unencumbered assets after the payment of all secured obligations and
administrative expenses to assure the Landlord that the Trustee or
Debtor-in-Possession will have sufficient funds to fulfill all of the
obligations of Tenant under this Lease; or

             (2) The Bankruptcy Court shall have entered an order segregating
sufficient cash payable to the Landlord, and the Trustee or Debtor-in-Possession
shall have granted to the Landlord a valid and perfected first lien and security
interest or mortgage in property of the Tenant, the Trustee or
Debtor-in-Possession, acceptable as to value and kind to the Landlord, in order
to secure to the Landlord the obligation of the Tenant, Trustee or
Debtor-in-Possession to cure the monetary or non-monetary defaults under the
Lease within the time period set forth above.

         (e) The following conditions shall apply to any assignment of this
Lease in Bankruptcy Proceedings:

             (1) If the Trustee or Debtor-in-Possession has assumed this Lease
and elects to assign the Lease to any other person, such interest or estate of
Tenant in this Lease may be so assigned only if the Landlord has acknowledged in
writing that the intended assignee can provide to the Landlord "adequate
assurance of future performance" (as hereinafter defined) of all of the terms,
covenants and conditions of this Lease to be performed by the Tenant.

             (2) For the purposes of this provision, Landlord and Tenant
acknowledge that, in the context of a bankruptcy proceeding, at a minimum,
"adequate assurance of future performance" shall mean that each of the following
conditions has been satisfied, and the Landlord has so acknowledged in writing:

                 A. The proposed assignee has submitted a current financial
statement audited by a Certified Public Accountant which shows the net worth and
working capital and amounts determined by Landlord to be sufficient to assure
the future performance by such assignee of all of Tenant's obligations under
this Lease;

                 B. The proposed assignee, if requested by the Landlord, shall
have obtained guarantees in form and substance satisfactory to the Landlord from
one or more persons who satisfy the Landlord's standards of creditworthiness;

                 C. The Landlord has obtained all consents or waivers from any
third party required under any lease, mortgage, financing arrangement, or other
agreement by which the Landlord is bound, in order to permit the Landlord to
consent to such assignment.

     40. Miscellaneous:

         (a) The rules and regulations attached hereto as Exhibit E, as well as
such rules and regulations as may hereafter be adopted by Landlord for the
safety, care and cleanliness of the Premises and the Building and the
preservation of good order thereon, are hereby expressly made a part hereof, and
Tenant agrees to obey all such rules

                                       26

<PAGE>   32
and regulations. The violation of any of such rules and regulations by Tenant
shall be deemed a breach of this Lease by Tenant affording Landlord all the
remedies set forth herein. Landlord shall not be responsible to Tenant for the
nonperformance by any other tenant or occupant of the Building of any of said
rules and regulations.

         (b) The term "Landlord" as used in this Lease, so far as covenants or
obligations on the part of Landlord are concerned, shall be limited to mean and
include only the owner or owners of the Building at the time in question, and in
the event of any transfer or transfers of the title thereto, Landlord herein
named (and in the case of any subsequent transfers or conveyances, the then
grantor) shall be automatically released from and after the date of such
transfer or conveyance of all liability in respect to the performance of any
covenants or obligations on the part of Landlord contained in this Lease
thereafter to be performed and relating to events occurring thereafter; provided
that any funds in the hands of Landlord or the then grantor at the time of such
transfer in which Tenant has an interest shall be turned over to the grantee,
and any amount then due and payable to Tenant by Landlord or the then grantor
under any provisions of this Lease shall be paid to Tenant.

         (c) As used in this Lease, the term "ordinary business hours" shall
mean the hours from 7:00 a.m. to 6:00 p.m., Monday through Friday, and 8:00 a.m.
to 1:00 p.m. on Saturday, except for New Year's Day, Presidents' Day, Memorial
Day, Independence Day, Labor Day, Thanksgiving Day, Christmas Day, and any other
national or state holiday as may be established from time to time ("Holidays").

         (d) This Lease shall be construed as though the covenants herein
between Landlord and Tenant are independent and not dependent and Tenant shall
not be entitled to any setoff of the rent or other amounts owing hereunder
against Landlord, if Landlord fails to perform its obligations set forth herein,
except as herein specifically set forth; provided, however, the foregoing shall
in no way impair the right of Tenant to commence a separate action against
Landlord for any violation by Landlord of the provisions hereof so long as
notice is first given to Landlord and any holder of a mortgage or deed of trust
covering the Building Complex or any portion thereof whose address Tenant has
been notified in writing and so long as an opportunity has been granted to
Landlord and such holder to correct such violation as provided in Paragraph
40(h) hereof.

         (e) If any clause or provision of this Lease is illegal, invalid or
unenforceable under present or future laws effective during the term of this
Lease, then and in that event, it is the intention of the parties hereto that
the remainder of this Lease shall not be affected thereby, and it is also the
intention of the parties to this Lease that in lieu of each clause or provision
of this Lease that is illegal, invalid or unenforceable, there shall be added as
a part of this Lease a clause or provision as similar in terms to such illegal,
invalid or unenforceable clause or provision as may be possible and be legal,
valid and enforceable, provided such addition does not increase or decrease the
obligations of or derogate from the rights or powers of either Landlord or
Tenant.

         (f) The captions of each paragraph are added as a matter of convenience
only and shall be considered of no effect in the construction of any provision
or provisions of this Lease.

         (g) Except as herein specifically set forth, all terms, conditions and
covenants to be observed and performed by the parties hereto shall be applicable
to and binding upon their respective heirs, administrators, executors,
successors and assigns. The terms, conditions and covenants hereof shall also be
considered to be covenants running with the land.

         (h) Except as otherwise specifically provided herein, in the event
Landlord shall fail to perform any of the agreements, terms, covenants or
conditions hereof on Landlord's part to be performed, and such nonperformance
shall continue for a period of thirty (30) days after written notice thereof,
from Tenant to Landlord, or if such performance cannot be reasonably had within
such thirty (30) day period, and Landlord shall not in good faith have commenced
such performance within such thirty (30) day period and proceed therewith to
completion, it shall be considered a default of Landlord under this Lease.
Tenant shall give written notice to Landlord in the matter herein set forth and
shall afford Landlord a reasonable opportunity to cure any such default. In
addition, Tenant shall send notice of such default by certified or registered
mail, with proper postage prepaid, to the holder of any mortgages

                                       27

<PAGE>   33
or deeds of trust covering the Building Complex or any portion thereof of whose
address Tenant has been notified in writing and shall afford such holder a
reasonable opportunity to cure any alleged default on Landlord's behalf.

         (i) If there is more than one entity or person which or who are the
Tenants under this Lease, the obligations imposed upon Tenant under this Lease
shall be joint and several.

         (j) No act or thing done by Landlord or Landlord's agent during the
term hereof, including but not limited to any agreement to accept surrender of
the Premises or to amend or modify this Lease, shall be deemed to be binding
upon Landlord unless such act or things shall be by an officer of Landlord or a
party designated in writing by Landlord as so authorized to act. The delivery of
keys to Landlord, or Landlord's agent, employees or officers shall not operate
as a termination of this Lease or a surrender of the Premises. No payment by
Tenant or receipt by Landlord of a lesser amount than the monthly rent herein
stipulated shall be deemed to be other than on account of the earliest
stipulated rent, nor shall any endorsement or statement on any check or any
letter accompanying any check or payment as rent be deemed an accord and
satisfaction and Landlord may accept such check or payment without prejudice to
Landlord's right to recover the balance of such rent or pursue any other remedy
available to Landlord.

         (k) Landlord shall have the right to construct other buildings or
improvements in any common area, or any other area designated by Landlord for
use by tenants or to change the location, character or make alterations of or
additions to any of said common areas or other areas. Landlord, during the
entire term of this Lease, shall have the right to change the number and name of
the Building at any time without liability to Tenant.

         (l) Tenant acknowledges and agrees that it has not relied upon any
statements, representations, agreements or warranties, except such as are
expressed in this Lease.

         (m) Notwithstanding anything to the contrary contained herein,
Landlord's liability under this Lease shall be limited to its interests in this
building.

         (n) Time is of the essence hereof.

         (o) Tenant and Landlord and the party executing this Lease on behalf of
each of them represent to each other that such party is authorized to do so by
requisite action of the board of directors or partners, as the case may be, and
agree upon request to deliver to each other a resolution or similar document to
that effect.

         (p) This Lease shall be governed by and construed in accordance with
the laws of the State where the Premises are located.

         (q) This Lease, together with the exhibits attached hereto, contains
the entire agreement of the parties and may not be amended or modified in any
manner except by an instrument in writing signed by both parties. Tenant shall
not record this Lease or a memorandum hereof.

         (r) In the event Landlord makes available any area in the Building
complex for use as an athletic/health facility, Tenant agrees that Landlord
shall not be liable for any injury or damage to persons or property arising out
of the use of such health facility by Tenant, its employees or invitees, and
further agrees to indemnify Landlord against any claims, demands or damages
associated therewith. Tenant further agrees to execute and deliver to Landlord,
upon request, an indemnification agreement, in form acceptable to Landlord, as a
condition precedent to use of any such health facility by Tenant and its
employees.

         (s) Tenant shall not use the name of the Building, the Building Complex
or the development in which the Building is situated as part of its legal or
trade name, nor for any purpose other than as an address for the business to be
conducted by Tenant in the Premises.

                                       28
<PAGE>   34
         (t) The submission or delivery of this document for examination and
review does not constitute an option, an offer to lease space in the Building or
an agreement to lease. This document shall have no binding effect on the parties
unless and until executed by both Landlord and Tenant.

         (u) Tenant may not record this Lease and any such recordation shall at
the option of Landlord, be a default of Tenant hereunder.

     IN WITNESS WHEREOF, Landlord and Tenant have executed this Lease the day
and year first above written.

                                    ADDENDUM

This Addendum is attached to and forms an integral part to the Lease by and
between Westmoor Business Park Ltd., LLLP, a Colorado limited liability limited
partnership and ChannelPoint, Inc., a Colorado corporation, for the Premises
known as Suite 210, 10155 Westmoor Drive, Westminster, Colorado and shall
supercede the terms and conditions of the Lease and where inconsistent govern
the rights and obligations of the parties. All definitions used herein shall
except as set forth herein have the meanings set forth in the Lease.

     1. Expansion Option: Tenant shall have the right to enlarge the area of the
Premises by a minimum of 6,000 additional square feet of rentable area. In the
event Tenant notifies Landlord ("Expansion Notice") of its desire to lease a
minimum of 6,000 additional square feet of rentable area, Landlord shall use
reasonable efforts to deliver said additional space ("Expansion Space") either
in the Tenant's existing Building or another building within Westmoor
Technology Park as determined by Landlord, within nine (9) months of the receipt
of Tenant's notice. Upon delivery of the Expansion Space the terms and
conditions of the Lease shall be modified as follows:

          A.   The term of the Lease for the Expansion Space shall be five (5)
               years.

          B.   If the Expansion Space is within the Building and the Expansion
               Notice is delivered within the first eighteen (18) months of the
               Lease Commencement Date, the Base Rent for the Expansion Space
               shall be the rate then in effect for the existing Premises and
               the Tenant Improvement Allowance shall be the same as for the
               Premises, provided the expansion occurs in space not previously
               leased.

          C.   The term of the Lease for the existing Premises shall be extended
               so as to be coterminous with the term of the Lease for the
               Expansion Space. The Base Rent for the Expansion Space shall be
               as provided for under this Lease for the Premises. If however,
               the Expansion Space has previously been occupied, the Tenant
               Improvement Allowance shall be the then equivalent to that which
               is being given for comparable space being leased within the Park
               at comparable rental rates.

          D.   If the Expansion Notice is received after the first eighteen (18)
               months of the Primary Lease Term or the expansion occurs at any
               time in a building within Westmoor Technology Park other than the
               Building, the Base Rental Rate shall be the then current market
               rate being charged for the Expansion Space as determined by
               Landlord.

          E.   The Expansion Notice shall be delivered no later than twelve (12)
               months prior to the expiration of the Primary Lease Term.

     2. Consolidation Option: In the event Tenant notifies Landlord
("Consolidation Notice") of its desire to consolidate its existing Premises with
a minimum of 6,000 rentable square feet of additional space into a new location
("Consolidation Space"), Landlord shall use reasonable efforts to deliver said
Consolidation Space either in Tenant's existing Building or another building
within Westmoor Technology Park as determined by Landlord, within nine (9)
months of the receipt of Tenant's Consolidation Notice. The terms and conditions
of the Lease with respect to the Consolidation Space are as follows:

          A.   A new Lease shall be entered into for the Consolidation Space
               ("Consolidation Space Lease"). The term of the Lease for the
               Consolidation Space shall be not less than five (5) years.

          B.   If the Consolidation Space is within the Building and
               Consolidation Notice is delivered within the first eighteen (18)
               months of the Lease Commencement Date, the Base Rent for

                                        1

<PAGE>   37
               the Consolidation Space shall be the rate then in effect for the
               existing Premises and the Tenant Improvement Allowance shall be
               the same as for the Premises, provided the consolidation occurs
               in space not previously leased.

          C.   If Consolidation Notice is received after the first eighteen (18)
               months of the Primary Lease Term or the consolidation occurs at
               any time in a building within Westmoor Technology Park other than
               the Building, the Base Rental Rate shall be the then current
               market rate being charged for the Consolidation Space as
               determined by Landlord, and the Tenant Improvement Allowance
               shall be equivalent to that then offered for space in the Park.

          D.   If the Consolidation Space under either (B) or (C) above has been
               previously leased and occupied, the Tenant Improvement Allowance
               shall be the then equivalent to that which is being changed for
               comparable space being re-leased within Westmoor Technology Park
               as determined by Landlord.

          E.   The Lease for the Premises shall be terminated effective as of
               the Commencement Date of the Consolidation Space Lease, and
               Tenant shall pay (i) the unamortized portion of all commissions
               paid under the Lease at an annual interest rate of 10%, and (ii)
               a cancellation charge based on the following formulas:

               o    If the Consolidation Space is more than 15,000 net rentable
                    square feet, but less than 20,000 net rentable square feet,
                    Tenant shall pay a lease cancellation charge equal to the
                    product of $7.50 multiplied by the net rentable square feet
                    of the Premises at the time of relocation;

               o    If the Consolidation Space is greater than 20,000 net
                    rentable square feet, but less than 25,000 net rentable
                    square feet, Tenant shall pay a lease cancellation charge
                    equal to the product of $5.00 multiplied by the net rentable
                    square feet of the Premises at the time of relocation;

               o    If the Consolidation Space is greater than 25,000 net
                    rentable square feet, but less than 30,000 net rentable
                    square feet, Tenant shall pay a lease cancellation charge
                    equal to the product of $2.50 multiplied by the net rentable
                    square feet of the Premises at the time of relocation; or

               o    If the Consolidation Space is greater than 30,000 net
                    rentable square feet, no lease cancellation charge shall be
                    payable.

          F.   Notwithstanding the foregoing, if additional space is available
               on the same floor as Tenant's Premises, Landlord shall not be
               obligated to consolidate Tenant's premises into another building
               in Westmoor Technology Park. Tenant shall then lease additional
               space on the same floor as the Premises, whether or not
               contiguous to the Premises, under the terms and conditions
               described in this Addendum in Section 1, Expansion Option.

          G.   The Consolidation Notice shall be delivered no later than twelve
               (12) months prior to the expiration of the Primary Lease Term.

                                        2
<PAGE>   38
     3. Termination Right: If Landlord is unable to provide Expansion Space in
the park for Tenant's expansion as detailed in Section 1 above or Consolidation
Space as detailed in Section 2 above, Tenant shall have the right to terminate
the Lease effective 180 days after Landlord notifies Tenant that it is unable to
provide additional space in the Park, such notification from Landlord shall be
delivered to Tenant no more than thirty (30) days after Landlord receives
Tenant's notice of the exercise of the Expansion Option or the Consolidation
Option. Following notice from Landlord that additional space in the Park is not
available, Tenant shall have forty-five (45) days to locate suitable space to
which to relocate and notify Landlord of Tenant's intent to terminate the Lease,
in which case Tenant shall be obligated for paying (i) the unamortized portion
of the Tenant Improvement Allowance and all commissions paid under the lease at
an annual interest rate of ten percent (10%), and (ii) three (3) months Base
Rent. During that forty-five (45) days, Tenant shall also have the option to
rescind its option to terminate the Lease, thus remaining in the Premises for
the remainder of the Lease Term.

<PAGE>   48
     5. Landlord Work and Tenant Extra Work.

         (a) Landlord will pay as much as the non-cash Tenant Finish Allowance
for the construction of Tenant's improvements in the Premises in accordance with
the Plans and Specifications (including, without limitation, all permits, taxes,
and construction management, architectural, engineering and construction
contractor's fees associated with the construction).

Tenant may be entitled to a credit against first Base Rents due for any Tenant
Finish Allowance which is not used.

         (b) Tenant will pay for the costs of all Tenant Extra Work (including,
without limitation, permits, taxes, and all space planning, architectural,
engineering and construction contractor's fees associated with the Tenant Extra
Work, and an amount sufficient to reimburse Landlord for overhead and related
expenses incurred in connection with the Tenant Extra Work). All requested
Tenant Extra Work will be subject to Landlord's prior written approval in
accordance with Paragraph 6.

     6. Landlord's Approval. Landlord, in its sole discretion, may withhold its
approval of any Tenant Space Plan, Tenant Work Drawings, Tenant Extra Work or
Change Orders which require work which:

         (a) exceeds or affects the structural integrity of the Building, or any
part of the heating, ventilating, air conditioning, plumbing, mechanical,
electrical, communication or other systems of the Building;

         (b) is not approved by the holder of any mortgage or deed of trust
encumbering the building at the time the work is proposed;

         (c) would not be approved by a prudent owner of property similar to the
Building;

         (d) violates any agreement which affects the Building or binds
Landlord;

         (e) Landlord reasonably believes will reduce the market value of the
Premises or the Building at the end of the Term;

         (f) does not conform to applicable building code or is not approved by
any governmental authority with jurisdiction over the Premises.

     7. Schedule of Tenant Improvement Activities.

         (a) On or before the Submission Date, Tenant will submit to Landlord
the improvement plan for the Premises (the "Tenant Space Plan"). Within five (5)
days after its receipt of the proposed Tenant Space Plan, Landlord shall provide
written notice of whether or not Landlord approves the proposed Tenant Space
Plan. If Landlord fails to give Tenant said notice by the fifth day, then the
Tenant Space Plan shall be deemed approved. If Landlord's notice objects to the
proposed Tenant Space Plan, the notice will set forth how the proposed Tenant
Space Plan fails to meet Landlord's requirements and how the proposed Tenant
Space Plan must be changed in order to overcome Landlord's objections. Tenant
will then submit a revised Tenant Space Plan to Landlord.

         (b) Within 15 days after approval or deemed approval of the Tenant
Space Plan, Tenant shall furnish to Landlord the construction drawings the
"CD's" for the construction of Tenant's Improvements (the "Improvements"). The
CD's shall be in such a condition so as to allow the issuance of a building
permit for the construction.

<PAGE>   49
     8. Payment for Tenant Extra Work. Tenant will pay to Landlord, in advance,
the total amount payable by Tenant for Tenant Extra Work.

     9. Change Orders. Tenant may authorize changes in work during construction
only by written instructions to Landlord's Representative on a form approved by
Landlord. All such changes will be subject to Landlord's prior written approval
in accordance with Paragraph 6. Prior to commencing any change, Landlord will
prepare and deliver to Tenant, for Tenant's approval, a change order (the
"Change Order") setting forth the total cost of such change, which will include
associated architectural, engineering and construction contractor's fees, and an
amount sufficient to reimburse Landlord for overhead and related expenses
incurred in connection with the Change Order. If Tenant fails to approve and pay
for such Change Order within five (5) days after delivery by Landlord, Tenant
will be deemed to have withdrawn the proposed change and Landlord will not
proceed to perform the change. Upon Landlord's receipt of Tenant's approval and
payment, Landlord will proceed to perform the change.

     10. Completion and Commencement Date. As provided in Section 2 and 20 of
the Lease, the Term of the Lease (and therefore Tenant's obligation for the
payment of Rent) shall not commence until Landlord has substantially completed
all work to be performed by Landlord as set forth in this Work Letter; provided,
however, that if Landlord is delayed in substantially completing such work as a
result of:

         (a) late submission of Tenant information, Space Plan or CD's;

         (b) Change Orders requested by Tenant;

         (c) delays in obtaining non-Building standard construction materials
requested by Tenant;

         (d) Tenant's failure to timely approve any item requiring Tenant's
approval;

         (e) any other delays by Tenant; and

         (f) any other act or omission of Tenant or Tenant's architects,
engineers, contractors or subcontractors (all of which shall be deemed to be
delays caused by Tenant),

         the foregoing shall be items of "Tenant Delay",

then the Commencement Date shall only be extended pursuant to Section 20 of the
Lease until the date on which Landlord would have substantially completed
performance of such work but for such delays. Except as provided in the Lease,
postponement of the commencement of the Term shall be in full settlement of all
claims that Tenant might otherwise have against Landlord by reason of the
Premises not being ready for occupancy by Tenant as of the originally scheduled
Commencement Date set forth in Section 2 of the Lease.

floor and the other units the first floor.

The system will be ducted to fan powered parallel flow type VAV boxes with
electric heating coils serving perimeter zones and cooling only pinch down boxes
serving interior spaces. On the average there will be one zone box for every
1,600 SF. Typically, each exposure will have two fan-powered boxes at an average
of 1,200 SF each, and the interior spaces will have a box for every 2,000 SF.
All zone boxes will be ducted to square ceiling diffusers during tenant finish
and all electrical and control wiring for the boxes will be done under the
tenant finish allowance.

          Option") to extend the term of the Lease for one (1) period of five
          (5) years ("Option Term").

          A.   The Renewal Option shall apply to all space under the Lease at
               the time the Renewal Notice is given to the Landlord and shall be
               on the following terms and conditions.

                                       2

<PAGE>   62
               1.   Written notice ("Renewal Notice") of exercise of the Renewal
                    Option shall be given to Landlord no later than nine (9)
                    months prior to the expiration of the Primary Lease Term. If
                    Tenant timely exercises a Renewal Option, the Lease shall be
                    deemed extended, and thereafter the parties shall execute an
                    amendment to the Lease setting forth the terms of the
                    extension.

               2.   Unless Landlord is timely notified by Tenant in accordance
                    with subparagraph (1) above, it shall be conclusively deemed
                    that Tenant does not desire to exercise the Renewal Option,
                    and the Lease shall expire in accordance with its terms, at
                    the end of the Primary Lease Term.

               3.   Tenant's right to exercise a Renewal Option shall be
                    conditioned upon Tenant not being in default under the Lease
                    at the time of the exercise of a Renewal Option or at the
                    time of commencement of the Option Term.

               4.   If Tenant exercises the Renewal Option, Landlord shall
                    provide Tenant with a tenant improvement allowance
                    comparable to that being provided by Landlord to other
                    tenants in the Westmoor Technology Park renewing their
                    leases for comparable space and for comparable terms.

               5.   The Renewal Option granted hereunder shall be upon the terms
                    and conditions contained in the Lease, except the rental to
                    be paid by Tenant for the Option Term shall be the then
                    current "Market Rate" for such period for similar quality
                    buildings in the competitive market but no less than the
                    Base Rent for the Premises on the Commencement Date of the
                    Primary Lease Term.

          B.   For the purposes of this paragraph 4, the term "Market Rate"
               shall mean an amount per rentable square foot per annum for the
               Premises which is representative of and comparable to the
               consideration then paid (as of the inception of the Renewal Term)
               for substantially equivalent lease transactions ("Comparable
               Transactions") for new or renewal leases which are executed
               within six

                                       3

<PAGE>   63

               (6) months of Tenant's exercise of the Renewal Option for
               substantially equivalent office space in the Westmoor Technology
               Park (the "Competitive Market") taking into account (i) the
               amount of space in the Premises; (ii) tenant improvement
               allowances, relocation allowances, free rent, landlord-paid
               brokerage commissions and other concessions required to attract
               new tenants or retain existing tenants; and (iii) the applicable
               base year or expense stop, if any, and as adjusted to reflect the
               applicable Base Year applicable to a Renewal Option, for
               operating expenses and real estate taxes; provided, however, that
               any non-arms length lease transactions entered into between
               landlords and tenants in the Competitive Market are expressly
               excluded from consideration in determining the Market Rent.

          C.   Failure to Renew. A failure to renew in the time and manner set
               forth herein and within the time period provided herein shall
               result in automatic termination of the Renewal Option.

          D.   Arbitration of Market Rate. Landlord shall provide written notice
               of its good faith determination of the Market Rate within thirty
               (30) days after Tenant provides its Renewal Notice to Landlord.
               Tenant shall have thirty (30) days ("Tenant's Review Period")
               after receipt of Landlord's notice of Landlord's determination of
               the Market Rate within which to accept Landlord's determination.
               In the event Tenant fails to accept in writing such rental
               proposed by Landlord then such proposal shall be deemed rejected,
               and Landlord and Tenant shall attempt to agree upon such Market
               Rate, using their best good faith efforts. If Landlord and Tenant
               fail to reach agreement within fifteen (15) days following
               Tenant's Review Period ("Outside Agreement Date"), then each
               party shall place in a separate envelope a final proposal as to
               the Market Rate and such determination shall be submitted to
               arbitration in accordance with subsections (1) through (5) below.
               If Landlord fails to timely deliver the initial written
               determination of the Market Rate which triggers Tenant's Review
               Period, then Tenant may commence such negotiations by providing
               the initial notice, in which event Landlord shall have thirty
               (30) days ("Landlord's Review Period") after receipt of Tenant's
               notice of the new rental within

                                       4

               which to accept such rental. In the event Landlord fails to
               accept in writing such rental proposed by Tenant, then such
               proposal shall be deemed rejected, and Landlord and Tenant shall
               attempt in good faith to agree upon such Market Rate, using their
               best good faith efforts. If Landlord and Tenant fail to reach
               agreement within fifteen (15) days following Landlord's Review
               Period (which shall be in such event, the "Outside Agreement
               Date" in lieu of the above definition of such date), then each
               party shall place in a separate sealed envelope its final
               proposal as to the Market Rate and such determination shall be
               submitted to arbitration in accordance with subsections (1)
               through (5) below.

               1.   Landlord and Tenant shall meet with each other within five
                    (5) business days of the Outside Agreement Date and exchange
                    the sealed envelopes and then open such envelopes in each
                    other's presence. If Landlord and Tenant do not mutually
                    agree upon the Market Rate within one (1) business day of
                    the exchange and opening of envelopes, then, within ten (10)
                    business days of the exchange and opening of envelopes,
                    Landlord and Tenant shall agree upon and jointly appoint a
                    single arbitrator who shall by profession be a competent MAT
                    appraiser with at least five (5) years experience in
                    properties in the vicinity of the Building Complex
                    unaffiliated with either Landlord or Tenant.

               2.   The arbitrator shall, within thirty (30) days of his or her
                    appointment, reach a decision as to whether the parties
                    shall use Landlord's or Tenant's submitted Market Rate, and
                    shall notify Landlord and Tenant of such determination.

               3.   If Landlord and Tenant fail to agree upon and appoint an
                    arbitrator, then the appointment of the arbitrator shall be
                    made by the Presiding Judge of the Jefferson County District
                    Court, or, if he or she refuses to act, by any judge having
                    jurisdiction over the parties.

               4.   The cost of arbitration shall be paid by Landlord and Tenant
                    equally.

               5.   The Market Rate as determined by the arbitration provision
                    specified above shall be final.

               6.   In addition to the Base Rent to be paid during the Option
                    Term, Tenant shall continue to be liable to pay its Pro Rata
                    Share of Operating Expenses, as more particularly provided
                    in the Lease.

5.   Right of First Refusal. In the event that Landlord (i) offers to lease
     space in the Building to a prospective tenant; or (ii) receives an offer to
     lease space in the Building from a prospective tenant which it is willing
     to accept (the events in (i) and (ii) are each a "Refusal Event" and such
     prospective tenant is hereafter referred to as the "Third Party" with
     respect to all or a portion of the balance of the leasable space in the
     east wing of the second floor of the Building, of which Landlord has
     control, which is hereafter referred to as the "Refusal Space") Landlord
     shall first offer to Tenant the right to lease the Refusal Space (the
     "Refusal Right") on the following terms, conditions and procedures:

     A.   Upon the occurrence of a Refusal Event, Landlord shall tender to
          Tenant notice (the "Refusal Notice") of the fact of the Refusal Event
          and the "Economic Terms" pursuant to which Landlord would be willing
          to lease the Refusal Space to the Third Party. The Economic Terms
          shall only include (x) the rentable area of the Refusal Space; (y) the
          Base Rent to be charged (z) the term and commencement date of the
          prospective lease; (aa) the amount of tenant finish allowance to be
          granted to the Third Party; (bb) the operating expense methodology;
          (cc) renewal and expansion options and (dd) the location of the
          Refusal Space.

                                       6

<PAGE>   66

     B.   Tenant shall have a period of five (5) business days from the tender
          of the Refusal Notice to give notice to Landlord ("Refusal Notice
          Response") of its irrevocable commitment to lease the Refusal Space
          upon the Economic Terms and upon the other terms and conditions of the
          Lease except that the term of the lease for the Refusal Space shall be
          the greater of (i) the time remaining in the Primary Lease Term or any
          Option Term or (ii) the term set forth in the Refusal Notice. Tenant's
          failure to timely tender the Refusal Notice Response shall irrevocably
          be deemed a rejection of the Refusal Space.

     C.   If Tenant rejects or is deemed to have rejected the Refusal Space,
          Landlord may (i) lease the Refusal Space to the Third Party on the
          Economic Terms and any other non Economic Terms and (ii) Tenant shall
          have no further right to lease the Refusal Space.

     D.   Tenant shall only be afforded the Refusal Right if Tenant is not in
          default of its obligations under the Lease at the time of the Refusal
          Event.

     E.   If Tenant timely exercises the Refusal Right, Tenant shall execute and
          deliver to Landlord all documentation reasonably requested by
          Landlord.

     Tenant hereby waives its Refusal Right with respect to Suite 201 of the
     Building, for which Landlord is currently negotiating a lease with ATP,
     Inc. and PPD Development, Inc.

6.   Consolidation Option: In the event Tenant notifies Landlord ("Consolidation
     Notice") of its desire to consolidate its existing Premises with a minimum
     of 100% of the Premises then being leased by Tenant of additional space
     into a new location ("Consolidation Space") (i.e. the rentable square
     footage of the Consolidation Space must be no less than double the rentable
     square footage of the Premises then being leased by Tenant at the time the
     Consolidation Notice is given), Landlord shall use reasonable efforts to
     deliver said Consolidation Space either in Tenant's existing Building or
     another building within Westmoor Technology Park as determined by Landlord
     within twelve (12) months of the receipt of Tenant's Consolidation Notice.
     The terms and conditions of the Lease with respect to the Consolidation
     Space are as follows:

                                       7

<PAGE>   67

     A.   A new Lease shall be entered into for the Consolidation Space
          ("Consolidation Space Lease"). The term of the Lease for the
          Consolidation Space shall be not less than five (5) years.

     B.   If the Consolidation Space is within the Building and Consolidation
          Notice is delivered within the first eighteen (18) months of the Lease
          Commencement Date, the Base Rent for the Consolidation Space shall be
          the rate then in effect for the existing Premises and the Tenant
          Improvement Allowance shall be the same as for the Premises, provided
          the consolidation occurs in space not previously leased.

     C.   If Consolidation Notice is received after the first eighteen (18)
          months of the Primary Lease Term or the consolidation occurs at any
          time in a building within Westmoor Technology Park other than the
          Building, the Base Rental Rate shall be the then current market rate
          being charged for the Consolidation Space as determined by Landlord,
          and the Tenant Improvement Allowance shall be equivalent to that then
          offered for space in the Westmoor Technology Park.

     D.   If the Consolidation Space under either (B) or (C) above has been
          previously leased and occupied, the Tenant Improvement Allowance shall
          be the then equivalent to that which is being changed for comparable
          space being re-leased within Westmoor Technology Park as determined by
          Landlord.

     E.   The Lease for the Premises shall be terminated effective as of the
          Commencement Date of the Consolidation Space Lease, and Tenant shall
          pay (i) the unamortized portion of all commissions paid under the
          Lease at an annual interest rate of 10%, and (ii) a cancellation
          charge based on the following formulas:

                                       8

<PAGE>   68

          o    If the amount of additional space being leased as part of the
               Consolidation Space is more than 25,000 net rentable square feet,
               but less than 35,000 net rentable square feet, Tenant shall pay a
               lease cancellation charge equal to the product of $7.50
               multiplied by the net rentable square feet of the Premises at the
               time of consolidation;

          o    If the amount of additional space being leased as part of the
               Consolidation Space is greater than 35,000 net rentable square
               feet, but less than 45,000 net rentable square feet, Tenant shall
               pay a lease cancellation charge equal to the product of $5.00
               multiplied by the net rentable square feet of the Premises at the
               time of consolidation;

          o    If the amount of additional space being leased as part of the
               Consolidation Space is greater than 45,000 net rentable square
               feet, but less than 55,000 net rentable square feet, Tenant shall
               pay a lease cancellation charge equal to the product of $2.50
               multiplied by the net rentable square feet of the Premises at the
               time of consolidation; or

          o    If the amount of additional space being leased as part of the
               Consolidation Space is greater than 55,000 net rentable square
               feet, no lease cancellation charge shall be payable.

     F.   Notwithstanding the foregoing, if additional space is available on the
          same floor as Tenant's Premises, Landlord shall not be obligated to
          consolidate Tenant's premises into another building in Westmoor
          Technology Park. Tenant shall then lease additional space on the same
          floor as the Premises, whether or not contiguous to the Premises,
          under the terms and conditions described in this Section.

     G.   The Consolidation Notice shall be delivered no later than twelve (12)
          months prior to the expiration of the Primary Lease Term.

7.   Termination Right: If Landlord is unable to provide Consolidation Space as
     detailed in the preceding Section, Tenant shall have the right to terminate
     the Lease effective 180 days after Landlord notifies Tenant that it is
     unable to provide additional space in the Westmoor Technology Park, such
     notification from Landlord shall be delivered to Tenant no more than thirty
     (30) days after Landlord receives Tenant's notice of the exercise of the
     Consolidation Option. Following notice from Landlord that additional space
     in the Westmoor Technology Park is not available, Tenant shall have
     forty-five (45) days to locate suitable space to which to relocate and
     notify Landlord of Tenant's intent to terminate the Lease, in which case
     Tenant shall be obligated for paying (i) the unamortized portion of the
     Tenant Improvement Allowance and all commissions paid under the lease at an
     annual interest rate of ten percent (10%), and (ii) three (3) months Base
     Rent. During that forty-five (45) days, Tenant shall also have the option
     to rescind its option to terminate the Lease, thus remaining in the
     Premises for the remainder of the Lease Term.

8.   Deletion of Lease Addendum. The Addendum attached to the Original Lease is
     hereby deleted and is null and void and of no further force or effect
     whatsoever.
