                13.7.2. The Lessor's entitlement to damages shall be assessed on
                        the basis that the Lessor should have observed the

                        mitigate damages shall not by itself constitute

                        surrender by operation of law.

                any such default or breach.

        14.7.   Any such appropriation by the Lessor of the Bank Guarantee or
                part thereof shall not be deemed and shall not operate to waive
                any default or breach by the Lessee.

        14.8.   If the Bank Guarantee is appropriated by the Lessor, then the
                Lessee shall forthwith upon demand by the Lessor pay to the

wear and tear thereof and damages by the elements excepted. The Tenant shall not
make any alterations, additions or improvements to said premises without the
Landlord's written consent; and all alterations, additions or improvements made
by either of the parties hereto upon the premises, except movable office
furniture and trade fixtures put in at the expense of the Tenant, shall be the
property of the Landlord and shall remain upon and be surrendered with the
premises at the termination of this lease without molestation or injury.

        9. MAINTENANCE: The Lessor agrees to maintain the building affixed to
said land in a condition substantially the same as it now exists. The Lessee
agrees to maintain interior of the individual let office in a condition
substantially the same as it now exists with respect to general maintenance. The
Lessee further agrees to keep common areas free of nuisances and debris of
Lessee. Lessor shall provide limited janitorial service, reasonable (once a
week) trash removal and shall maintain the grounds, including landscaping and
snow removal, in a condition required in maintaining an office building.

        10. UTILITIES: The Landlord agrees that he will pay all reasonable
charges for gas or oil for heating, and for water consumed on the premises or
any part thereof during the said term as they shall become due. Landlord shall

<PAGE>   4

have the right to either pay the cost of electricity (which Lessor shall pay
initially), or to allocate the cost of electricity based upon square footage as
additional rent in the event that in Lessors sole discretion Tenant uses a
disproportionate amount of electricity, but landlord shall allocate and pay the
cost of electricity for common area square footage.

        11. TAXES: Landlord shall pay all taxes, assessments and charges which
shall be assessed and levied upon the leased premises or any part thereof during
the said term as they shall become due.

at all reasonable hours of the day and only in a commercially reasonable manner,
to inspect and/or make such repairs to the leased premises as the Lessor may
reasonably desire, without prosecution for such intrusion. The Lessor shall at
all times accord reasonable care to the Lessee's property.

        13. OBSERVANCE OF LAWS: Tenant shall duly obey and comply with all
public laws, ordinances, rules or regulations relating to the use of the leased
premises; provided, however, that any installation of fire prevention apparatus,
electric rewiring, plumbing changes or structural changes in the building on the
lease premises, required by any such law, ordinance, rule or regulation, shall
be made by Landlord without expense to Tenant.

        14. DEFAULT: "Default shall be defined as follows: failure by either of
the parties hereto to perform any covenant required to be performed by such
party under the terms and provisions of this lease, including Tenant's covenant
to pay rent by Due Date. Default shall automatically accelerate rent due, for
the full amount of rent due, during the term of this Lease, and allow Landlord
to demand and seize the security deposit made herewith. Tenant may not be liable
for entire accelerated amount because Landlord shall attempt to minimize damage,
by re-rental of the premises. Tenant hereby waives any notice of

<PAGE>   5

acceleration.

        15. EVICTION: In the event that Tenant fails to pay rent by the Due
Date, Landlord may at its option, serve upon Tenant a Notice to Quit, and both
Tenant and Landlord agree that eviction may be by Summary Proceedings. In
addition, Landlord may at its option use self-help and re-enter and repossess
the premises and remove and put out each and every occupant. So long as
Landlord's actions are reasonable and in accordance herewith, Tenant shall not
be entitled to any damages from Landlord on account of his re-entry.

        16. TERMINATION BY REASON OF DEFAULT: In the event that Tenant fails to
pay rent seven (7) days after service upon Tenant of Notice to Quit, Landlord
may at its option, immediately terminate this lease and pursue all legal
remedies. In the event that either party defaults for any reason, other than
Tenant's nonpayment of rent, and such default continues for fifteen days after
service of notice upon the defaulting party by the non-defaulting party, this
lease may be terminated, at the option of the non-defaulting party, fifteen days
after service of the notice. Such termination shall not relieve the defaulting
party from liability to the other party for such damages as may be suffered by
reason of such default.

        17. EXPENSES, DAMAGES LATE CHARGES AND INTEREST: Tenant hereby agrees to
pay Landlord expenses and costs, including payroll costs and actual attorneys
fees, reasonably incurred by Landlord but not to exceed $900.00, because of
Tenant's default and those fees resulting from any action for Summary
Proceedings against Tenant. The Landlord shall be entitled to, and Tenant agrees
to pay, interest on account of all rents past due 30 days from Due Date, same to
be charged at the rate of one and one half (1 1/2%) percent per month. Landlord
shall be entitled to and Tenant agrees to pay, a late fee of Twenty Five and
00/100 ($25.00) dollars if rent is not received within Fifteen (15) days of the
Due Date. Said interest charge and late fee shall be included as service charges
and be deemed part of additional rent. Any rent

<PAGE>   6

check tendered to the Landlord returned by the bank shall obligate the Tenant to
pay the Landlord Twenty Five and 00/100 ($25.00) Dollars immediately upon
receipt of notice, plus reimbursement of Landlord's bank charges for the
returned check.

        18. REMEDIES NOT EXCLUSIVE: It is agreed that each and every right,
remedy and benefit Provided by this lease shall be cumulative and shall not be

the property, office furniture and equipment placed upon the premises let
hereby. In the event of Tenant's default in the payments and covenants

or nature whatsoever sustained as a result of injury, loss or damage sustained
by any person who is in the employ of the Lessee or who is injured as a result

or, at the option of Tenant, as of the date on which the premises shall become
unsuitable for Tenant's regular business by reason of such taking, provided,
however, that if only a part of the leased premises shall be so taken, such
termination shall be at the option of Tenant only. If such a taking of only a
part of the leased premises occurs and Tenant elects not to terminate the lease,
there shall be an proportionate reduction of the rent to be paid under this
lease from and after the date such possession is taken for public use. Tenant

(90) days of said casualty without affecting Tenant's duties hereunder;

the Landlord personal information data on Exhibit "B" which shall be held in the

authorization of any agents or individuals of Lessee.

        26. WAIVER AND SEVERABILITY: No waiver of any rights hereunder shall be
deemed as a continuing waiver, nor shall it in any way prejudice any rights or
remedies provided hereby. The terms, conditions and covenants in this agreement
are severable, and the invalidity of one shall in no way affect the enforcement
of others.

written notice mailed or delivered to the premises leased hereunder, shall
