accounting principles or other recognized accounting practices, consistently
applied, including all additional direct costs and expenses of operation and
maintenance which Landlord determines that it would have paid or incurred during
such~ year if the Building had been one hundred percent (100%) occupied,
including by way of illustration and not limitation: real estate taxes and
assessments; insurance premiums; electrical and other utility charges including
common area lighting, parking and building lighting other than separately
billed electrical and other charges paid by Tenant as provided in this Lease;
service and other charges paid or incurred in the operation and maintenance of
the heating, ventilating and air-conditioning systems; cleaning and other
janitorial services, tools and supplies; repair costs; snow removal and
landscape maintenance costs; license and permit fees; management fees; and in

expenses, including those which would normally be amortized over a period not
exceeding five (5) years. There shall also be included in Operating Expenses the
cost of any capital improvement made to the Building by Landlord after the date
of this Lease, which is required under any governmental law or regulation that

whichever is higher.

per square foot for a particular calendar year (herein referred to collectively
as the "Additional Rent") shall be estimated annually by Landlord, and written
notice thereof shall be given to Tenant at least thirty (30) days prior to the
beginning of each calendar year. Tenant shall pay each month, at the same time

(1/12) of the estimated Additional Adjustment. If "Operating Expenses" increase
during a calendar year, Landlord may increase the estimated Additional Rent
during such year by giving Tenant written notice to that effect, and thereafter
Tenant shall pay to the Landlord, in each of the remaining months of sch year,
an amount equal to the amount of such increase in the Additional Rent divided by
the number of months remaining in such year.

Within ninety (90) days after the end of each such calendar year, Landlord shall
prepare and deliver to Tenant a statement showing in reasonable detail the
actual Operating Expenses and Tenant's actual Annual Rental Adjustment. Within
thirty (30) days after receipt of the aforementioned statement, Tenant shall pay
to Landlord, or Landlord shall credit against the next rent payment or payments
due from Tenant, as the case may be, the difference between the Tenant's Actual
Annual Rental Adjustment for the preceding calendar year and the estimated
amount paid by Tenant during such year.

      "With respect to a calendar year determination, the amount produced
      by the following formula:

          "Provided, however, that in the application of the second formula,
          above, the total Operating Expenses will be the total of the actual
          Operating Expenses incurred during the period between the end of the
          last preceding calendar year and the Expiration Date and an amount
          equal to the Operating Expenses incurred between the same month and
          day as in the Expiration Date during the last preceding calendar year
          and the end of that calendar year.

          "And, provided further that there shall be no Additional Rent payable
          if the application of the appropriate formula fails to produce a
          result that is in excess of $0.

          "Tenant or Tenant's accountants shall have the right to inspect and
          copy, at reasonable times and in a reasonable manner, following the
          delivery of Landlord's invoice for Additional Rent in order to verify
          the amounts thereof. If Tenant shall dispute any item or items
          included in the determination of Operating Expenses for a particular
          period, and such dispute is not resolved by the parties hereto within
          ninety (90) days after the invoice for Additional Rent was delivered
          to Tenant, then either party may, within thirty (30) days thereafter,
          request that a firm of independent certified public accountants
          selected by Landlord render an opinion as to whether or not the
          disput- ed item or items may properly be included in the determination
          of Additional Rental; and the opinion of such firm on the matter shall
          be conclusive and binding upon the parties hereto. The fees and
          expenses incurred in obtaining such an opinion shall be borne by the
          party adversely affected thereby; and if more than one item is
          disputed and the opinion adversely affects both parties, the fees and
          expenses shall be apportioned accordingly. If Tenant shall not dispute
          any item or items included in the determination of Additional Rent for
          a particular period within ninety (90) days after the invoice for
          Additional Rent was delivered to it, Tenant shall be deemed to have
          approved such statement."

3.03 - Service Charge. If any monthly installment of Base Rent or Additional
Rent provided for in this Lease, or any part thereof, is not paid within the
applicable period specified in Section 17.01(A), it shall be subject to a
service charge of one and one-half percent (1.5%) of the unpaid rent due for
each month or fraction thereof (or such lesser percentage as may be the maximum
amount permitted by law) until paid.

obligations under this Lease, Tenant has deposited with Landlord the sum
specified in G of the Basic Lease Provisions, which sum shall be held by
Landlord as a security deposit during the term of this Lease. If Tenant performs

required to be performed and observed by it, Landlord shall return the security
deposit, or balance thereof then held by Landlord, without interest, to Tenant
within thirty (30) days after the Expiration Date or after Tenant surrenders
possession of the Premises, whichever is later. In the event of a default by
Tenant in the payment of rent or the performance or observance of any of the
other terms, conditions or covenants of this Lease, then Landlord may, at its
option and without notice, apply all or any part of the security deposit in
payment of such rent or to cure any other such default; and if Landlord does so,
Tenant shall, upon request, deposit with Landlord the amount so applied so that
Landlord will have on hand at all times during the term of this Lease the full
amount of the security deposit. Landlord shall not be required to hold the
security deposit in a separate or trust account, but may commingle it with
Landlord's other funds.

In the event of a sale of the land and Building of which the Premises are a
part, Landlord shall have the right to transfer the security deposit to its
purchaser, and Landlord shall thereupon be released by Tenant from all
responsibility for the return of such deposit; and Tenant agrees to look solely
to the new purchaser or lessee for the return of such deposit. In the event of

Building or the Premises) by fire or other casualty, then either party hereto
may, at its option, terminate this Lease by giving the other party written
notice of such termination within thirty (30) days after the date of such
casualty. In such event, rent shall be apportioned to an shall cease as of the
date of such casualty. If neither party exercises this option, then the Premises
shall be reconstructed and restored, at Landlord's expense, to substantially the
same condition as they were prior to the casualty; provided however that the
Landlord's obligation hereunder shall be limited to the reconstruction of such
of the tenant finish improvements as were originally required to be made by
Landlord in accordance with the plans and specifications referred to in
Section 5.01; and further provided that, if Tenant has made any additional
improvements pursuant to Section 9.02, Tenant shall reimburse Landlord for the
cost of reconstructing the same. In the event of such reconstruction, rent shall
be abated from the date of the casualty until substantial completion.of the
recon- struction repairs; and this Lease shall continue in full force and effect
for the balance of the term.

10.02 - Partial Destruction of the Premises. If the Premises should be damaged
by fire or other casualty, but not substantially destroyed or damaged to the
extent provided in Section 10.01, then such damaged part of the Premises shall
be reconstructed and restored, at Landlord's expense, to substantially the same
condition as it was prior to the casualty; provided however that Landlord's
obligation hereunder shall be limited to the reconstruction of such of the
tenant finish improvements as were originally required to be made by Landlord in
accordance with the plans and specifications referred to in Section 5.01, and
further provided that, if Tenant has made any additional improvements pursuant
to Section 9.02, Tenant shall reimburse Landlord for the cost or reconstructing
the same. In such event, if the damage is expected to prevent Tenant from
carrying on its business in the Premises to an extent exceeding 30% of its
normal business activity, rent shall be abated in the proportion which the
approximate area of the damaged part bears to the total area in the Premises
from the date of the casualty until substantial completion of the reconstruction
repairs; and this Lease shall continue in full force and effect for the balance
of the term. Landlord shall use reasonable diligence in completing such
reconstruction repairs, but in the event Landlord fails to complete the same
within one hundred eighty (180) days from the date of the casualty, Tenant may,
at its option, terminate this Lease upon giving Landlord written notice to that
effct, whereupon both parties shall be released from all further obligations and
liability hereunder.

that Landlord shall not be responsible for, and shall not be obligated to insure
against, any loss of or damage, to any of Tenant's property or any additional
improvements which Tenant may construct on the Premises as provided in Section

Section 5.01 or any alterations or improvements made by Tenant pursuant to
Section 9.02 result in an increase in the premiums charge during the term of
this Lease on the casualty insurance carried by Landlord on the Building, then
the cost of such increase in insurance premiums shall be borne by Tenant, who
shall be separately billed theref or and shall reimburse Landlord for the same
as additional rent.

other's employees, agents, customers and invitees from any and all liability for

the Building by reason of fire or other casualty which could be insured against
under a standard fire and extended coverage insurance policy, regardless of
cause, including the negligence of the other party and its employees, agents,
customers and invitees. Each party further agrees that such insurance carried by
either of them shall contain a clause whereby the insurance company waives its
right of subrogation against the other party. Because the provisions of this
Section 10.04 are intended to preclude the assignment of any claim mentioned
herein by way of subrogation or otherwise to an insurance company or any other

same. Tenant's obligation to indemnify Landlord hereunder shall include the duty

domain or shall be conveyed to such authority in lieu of such taking, and if

untenantable and inadequate for use by Tenant for the purpose for which they
were leased, then Tenant may, at its option, terminate this Lease as of the date
Tenant is required to surrender possession of the Premises by giving Landlord
notice of such termination. If a part of the Premises shall be taken or conveyed
but the remaining part is tenantable and adequate for Tenant's use, then this
Lease shall be terminated as to the part taken or conveyed as of the date Tenant
surrenders possession; Landlord shall make such repairs, alterations and
improvements as may be necessary to render the part not taken or conveyed

If, because of any act or omission of Tenant or anyone claiming by, through or
under Tenant, any mechanic's lien or other lien shall be filed against the
Premises or in the Building or against other property of Landlord (whether or

expense, cause the same to be discharged of record within thirty (30) days after
the date of filing thereof, and shall also indemnify Landlord and hold it
harmless from any and all claims, losses, damages, judgements, settlements,
costs and expenses, including attorneys' fees, resulting therefrom or by reason
thereof. Landlord may, but shall not be obligated to, pay the claim upon which
such lien is based so as to have such lien released of record; and, if Landlord

taxes, levied or imposed upon Tenant's business operations in the Premises and
any personal property or similar taxes levied or imposed upon Tenant's trade
fixtures, leasehold improvements or personal property located within the
Premises. In the event any such taxes, assessments, fees or charges are charged
to the account of, or are levied or imposed upon the property of, Landlord,
Tenant shall reimburse Landlord for the same as additional rent. Notwithstanding
the foregoing, Tenant shall have the right to contest in good faith any such
item and to defer payment, if required, until after Tenant's liability theref or

ARTICLE XV -- ASSIGNMENT AND SUBLETTING
----------------------------------------

Tenant will not assign this Lease or sublet the Premises, or any part thereof,

permitted assignment or subletting, Tenant shall nevertheless, at all times,
remain fully responsible and liable for the payment of rent and the performance
and observance of all of Tenant's other obligations under the terms, conditions
and covenants of this Lease. No assignment or subletting of the Premises or any
part thereof shall be binding upon Landlord unless such assignee or subtenant
shall deliver to Landlord an instrument (in recordable form, if requested)
containing an agreement of assumption of all of Tenant's obligations under this
Lease. Upon the occurrence of an event of default, if all or any part of the
Premises are then assigned or sublet, Landlord, in addition to any other
remedies provided by this Lease or by law, may, at its option, collect directly
from the assignee or subtenant all rent becoming due to Landlord by reason of
the assignment or subletting. Any collection by Landlord from the assignee or
subtenant shall not be construed to constitute a waiver or release of Tenant
from the further performance of its obligations under this Lease or the making
of a new lease with such assignee or subtenant.

Landlord may, in its sole discretion, refuse to give its consent to any proposed
assignee or subtenant, the prevailing market or quoted rental rates for space in
the Building or other comparable buildings, and the proposed use of the Premises
by, or business of, the proposed assignee or subtenant. If Landlord refuses to
give its consent to any proposed assignment or subletting, Landlord may, at its

terminate this Lease by giving Tenant thirty (30) days prior written notice of
such termination, whereupon each party shall be released from all further
obligations and liability hereunder.

operate to release  Landlord  from  liability  hereunder  after the date of such
conveyance as provided in Section 17.04.

to any mortgage presently existing or hereafter placed upon the Building by so

of either document. Tenant shall, at Landlord's request, execute and deliver to
Landlord, without cost, any instrument which may be deemed necessary or
desirable by Landlord to confirm the subordination of this Lease; and, if Tenant
fails or refuses to do so, Landlord may execute such instrument in the name and
as the act of Tenant. Notwithstanding the foregoing, no default by Landlord,
under any such mortgage shall affect Tenant's rights hereunder so long as Tenant
is not in default under this Lease. Tenant shall, in the event any proceedings
are brought for the foreclosure of any such mortgage, attorn to the purchaser
upon any such foreclosure and recognize such purchaser as the landlord under
this Lease.

B.   Tenant shall fail to perform or observe any term, condition, covenant or
     obligation required to be performed or observed by it under this Lease for
     a period of thirty (30) days after notice thereof from Landlord; provided,
     however, that if the term, condition, covenant or obligation to be
     performed by Tenant is of such nature that the same cannot reasonably be
     performed within such thirty day period, such default shall be deemed to
     have been cured if Tenant commences such performance within said thirty day
     period and thereafter diligently undertakes to complete the same.

C.   Tenant shall vacate or abandon the Premises, or fail to occupy the Premises
     for a period of thirty (30)'days.

     of the same).

17.02 - Remedies of Landlord. Upon the occurrence of any event of default set
forth in Section 1701, Landlord shall have the following rights and remedies, in
addition to those alowed by law, any one or more of, which may be exercised
without further notice to or demand upon Tenant:

A.   Landlord may apply the security deposit or re-enter the Premises and cure
     any default of Tenant, in which event Tenant shall reimburse Landlord as
     additional rent for any costs and expenses which Landlord may incur to cure
     such default; and Landlord shall not be liable to Tenant for any loss or
     damage which Tenant may sustain by reason of Landlord's negligence or
     otherwise.

B.   (1)  Landlord may terminate this Lease as of the date of such default,
          in which event: (i) neither Tenant nor any person claiming under or

     (2)  Landlord may, without terminating this Lease, re-enter the Premises
          and re-let all or any part of the Premises for a term different from
          that which would otherwise have constituted the balance of the term of
          this Lease and for rent and on terms and conditions different from
          those contained herein, whereupon Tenant shall be obligated to pay to
          Landlord as liquidated damages the difference between the rent
          provided for herein and that provided for in any lease covering a
          subsequent re-letting of the Premises, for the period which would

the breach of this Lease by Landlord if it shall fail to perform or observe any
term, condition, covenant or obligation required to be performed or observed by
it under this Lease for a period of thirty (30) days after notice thereof from
Tenant; provided, however, that if the term, condition, covenant or obligation
to be performed by Landlord is of such nature that the sane cannot reasonably be
performed within such thirty day period, such default shall be deemed to have
been cured if Landlord commences such performance within said thirty day period
and thereafter diligently undertakes to complete the same. Upon the occurrence
of any such default, Tenant may sue for injunctive relief or to recover damages
for any loss resulting from the breach, but Tenant shall not be entitled to
terminate this Lease or withhold or abate any rent due hereunder.
