         4.       Occupancy.

                  (a)      Sublessee shall use and occupy the Subleased Premises
         solely for business offices.

                  (b)      Sublessee covenants that it will occupy the Subleased
         Premises in accordance with the terms of the Lease and will not suffer
         to be done or omit to do any act that may result in a violation of or a
         default under any of the terms and conditions of the Lease, or render
         Sublessor liable for any charge or expense. Sublessee further covenants
         and agrees to indemnify Sublessor against and hold Sublessor harmless
         from any loss or liability arising out of, by reason of, or resulting
         from, Sublessee's failure to perform or observe any of the terms and
         conditions of the Lease pertaining to the Subleased Premises. Any other
         provision in this Sublease to the contrary notwithstanding, Sublessee
         shall pay to Sublessor, as additional rent, any and all sums that
         Sublessor may be required to pay to Lessor arising out of, by reason
         of, or resulting from Sublessee's failure to perform or observe one or
         more of the terms and conditions of the Lease pertaining to the
         Subleased Premises.

                  (c)      Sublessee agrees that Sublessor shall not be required
         to perform any of the covenants and obligations of Lessor under the
         Lease and, insofar as any of the covenants and obligations of Sublessor
         hereunder are required to be performed under the Lease by Lessor
         thereunder, Sublessee acknowledges that Sublessor shall be entitled to
         look to Lessor for such performance. Any default or failure of
         performance by Lessor shall not affect this Sublease or waive or defer
         any of Sublessee's obligations hereunder; provided, however, that in
         the event of any such default or failure of performance by Lessor,
         Sublessor shall take such action as may reasonably be required, under
         the circumstances, to secure such performance upon Sublessee's written
         request therefor.

                  (d)      If any event described in Section 12.01 of the Lease
         shall occur with respect to Sublessee or Sublessee's property or if
         Sublessee shall default in the payment of rent or additional rent
         hereunder or in the performance or observance of any of the terms,
         covenants and conditions of this Sublease or of the Lease on the part
         of Sublessee to be performed or observed, Sublessor shall be entitled
         to the rights and remedies herein provided or reserved by Lessor in the
         Lease, including the rights and remedies set forth in Section 12.02
         thereof.

         5.       Rent. Commencing on the ninetieth day after the earlier of (i)
Sublessee's occupancy or (ii) _ days after Sublessor delivers the Subleased
Premises to Sublessee after completing Sublessor's Work (described in Section 20
below) (the "Rent Commencement Date"), Sublessee shall pay to Sublessor an
annual rent (the "Rent") of One Hundred Eighty-Two Thousand Three Hundred
Forty-Three Dollars and 00 Cents ($182,343.00) in equal monthly installments of
Fifteen Thousand One Hundred Ninety-Five Dollars and Twenty-Five Cents
($15,195.25), payable in advance on the first day of each month. If the Rent
Commencement Date occurs on a day other than the first day of a month then
rent for the month in which such date occurs shall be prorated based on the
number of days remaining in that month and shall be due and payable on the Rent
Commencement Date. Commencing on the Rent Commencement Date, Sublessee shall
also pay to Sublessor its pro rata share (the "Pro Rata Share") of such
additional rent as is set forth in the Lease, including specifically

<PAGE>   3


the Pro Rata Share of the Operating Expense adjustment to Sublessor's Monthly
Base Rent as set forth in Section 22.03 of the Lease. The Pro Rata Share shall
be determined by dividing the rentable square footage of the Subleased Premises
by the rentable square footage of the Leased Premises. The Rent shall be subject
to annual CPI adjustments as set forth in Section 22.02 of the Lease.

         6.       Sublessee's Improvements. Subject to the provisions of the
Lease, any alterations, decorations, installations, additions or improvements in
or to the Subleased Premises shall be made by Sublessee, at Sublessee's expense,
and shall be subject to the prior written consent of Sublessor and Lessor. At
the request of Sublessor or Lessor, any such alterations, decorations,
installations, additions or improvements made by Sublessee shall be removed by
Sublessee, and Sublessee shall restore the Subleased Premises to its condition
at the time possession thereof was delivered to Sublessee, ordinary wear and
tear excepted, at Sublessee's cost and expense, at or prior to the expiration or
sooner termination of the term hereof.

         7.       Security Deposit. On the date of execution of this Sublease by
Sublessee, there shall be due and payable by Sublessee a security deposit in the
amount of Fifteen Thousand One Hundred Ninety-Five Dollars and Twenty-Five Cents
($15,195.25) to be held by Sublessor for the performance by Sublessee of
Sublessee's covenants and obligations under this Sublease, it being expressly
understood that the deposit shall not be considered an advance payment of rental
or a measure of Sublessor's or Lessor's damage in case of default by Sublessee.
Upon the occurrence of any event of default by Sublessee or breach by Sublessee
of Sublessee's covenants under this Sublease, Sublessor may, from time to time,
without prejudice to any other remedy, use the security deposit to the extent
necessary to make good any arrears of rent and/or damage, injury, expense or
liability caused to Sublessor by the event of default or breach of covenant, any
remaining balance of the security deposit to be returned by Sublessor to
Sublessee upon termination of the Sublease.

         8.       Condemnation and/or Termination. If the whole or any part of
the Subleased Premises shall be taken or condemned in any manner by any
competent authority for any public or quasi-public use, or if the Lessor under
the Lease or Sublessor as Lessee thereunder shall terminate the Lease as
provided in the Lease, in any such event, the term of this Sublease shall cease
and terminate as of the date of vesting of title or such condemnation or
termination as the case may be. Sublessee shall not participate in any
compensation awarded upon a total or partial taking of the Subleased Premises.

         9.       No Assignment or Subletting. Sublessee, for itself, its
successors and assigns, expressly covenants that it shall not assign, mortgage
or encumber this Sublease, nor sublet, nor suffer or permit the Subleased
Premises or any part thereof to be used by others, without the prior written
consent of Sublessor in each instance.

         10.      Expansion/Renewal Options. Any expansion, renewal or other
option provided to Sublessor in the Lease shall not be extended to or exercised
by Sublessee.

         11.      Quiet Enjoyment. Sublessor covenants and agrees with Sublessee
that, provided Sublessee pays and performs all of its covenants, agreements and
obligations under this Sublease, Sublessee may peaceably and quietly enjoy the

by Tenant to Landlord at lease execution. Adjusted Monthly Base Rent shall be
prorated for partial months within the Term. All charges, costs and sums
required to be paid by Tenant to Landlord under this Lease including Exhibit

services:

             (1) heat and air-conditioning in the Premises, Monday through
    Friday from 8:00 a.m. to 6:00 p.m., excluding national holidays, to the
    extent reasonably necessary for the comfortable occupancy of the Premises

    requirements and restrictions) and in the absence of the use of machines,
    equipment or devices which affect the temperature otherwise maintained in
    the Premises; (2) city water from the regular Building fixtures for
    drinking, lavatory and toilet purposes only; (3) customary cleaning and
    janitorial services in the Premises Monday through Friday, excluding

    removal in the "Common Areas" (hereinafter defined); (5) adequate passenger
    elevator service in common with other tenants of the Building; (6)
    electricity for normal building usage; if the Tenant shall require
    electrical current or install electrical equipment including but not limited
    to electrical heating, refrigeration equipment, unusually heavy computer
    use, electronic data processing machines, punch card machines, or machines
    or equipment using current which will, in the reasonable judgment of the
    Landlord, in any way materially increase the amount of the electricity
    usually furnished for use in general office space. Tenant will obtain prior
    written approval from the Landlord and pay periodically for the additional
    direct expense involved, including any installation cost of equipment for
    metering said electricity; and (7) all lamps furnished to the Tenant by
    Landlord shall be paid for by the Tenant at not more than the current retail
    price charged therefor.

    5.02     ADDITIONAL AND AFTER-HOUR SERVICES

             Landlord shall not be obligated to furnish any services or
utilities, other than those stated in 5.01 above. If Landlord elects to furnish
services or utilities requested by Tenant in addition to those listed in 5.01 or
at times other than those stated in 5.01, Tenant shall pay to Landlord the
prevailing charges for such services and utilities, within ten (10) days after
billing. If Tenant fails to make any such payment, Landlord may, without notice
to Tenant and in addition to Landlord's other remedies under this Lease,
discontinue any or all of such additional or after-hours services. No such
discontinuance of any service shall result in any liability of Landlord to
Tenant or be considered an eviction or a disturbance of Tenant's use of the
Premises. Landlord shall provide air-conditioning in the Premises Saturday from
8:00 a.m. to 12:00 p.m. at no cost to Tenant.

5.03         DELAYS IN FURNISHING SERVICES

             If as a result of any failure to furnish or delay in furnishing
    any of the services described in 5.01, the Premises are rendered
    substantially untenantable for said period of seventy-two (72) consecutive
    hours and Tenant is unable to occupy the Premises due to such
    untenantability, then, commencing upon the expiration of said 72-hour
    period, Adjusted Monthly Base Rent shall abate for the duration of such
    untenantability until Tenant is able to resume or does resume occupancy of
    the Premises. Tenant agrees that Landlord shall not be liable for damages
    for failure to furnish or delay in furnishing any service if attributable
    to any of the causes described in 26.06 and if not thus attributable, then
    only to the extent of abatement of Rent. No failure or delay shall be
    considered to be an eviction or disturbance of Tenant's use or possession
    of Premises.


                                                                         Page 3

the Building outside the Premises in connection with providing telephone
service to the Premises.

diminution or alteration of the Common Areas be considered a constructive or
actual eviction.


                                                                         Page 4

relating to the condition of the Premises. No agreement of Landlord to alter,
remodel, decorate, clean or improve the Premises, the Building, the Common
Areas or the Complex and no representation regarding the condition of the
Premises, the Building, the Common Areas or the Complex has been made by or on

cause its officers, agents, contractors and employees to so comply and to use
its best efforts to cause its customers, invitees, concessionaires, suppliers

change the area, level, location or arrangement of parking areas and other
facilities located in the Common Areas; to close all or any portion of the
Common Areas to such extent as may, in the opinion of Landlord, be legally
sufficient to prevent a dedication thereof or accrual of any rights to any
person or the public therein; to close temporarily all or any part of the
parking areas or parking facilities; and to do and perform such other acts in
and to the Common Areas as, in the exercise of good business judgment, Landlord
shall determine to be advisable. Landlord will operate and maintain the Common

from time to time.

        10. ALTERATION AND IMPROVEMENTS SUBSEQUENT TO INITIAL OCCUPANCY

10.01    TENANT'S ALTERATIONS SUBSEQUENT TO INITIAL OCCUPANCY

         Tenant shall not, without the prior written consent of Landlord (which
consent shall not be unreasonably withheld or delayed, make or cause to be made
any structural alterations, improvements, additions or installations in or to
the Premises subsequent to the initial occupancy of the Premises by Tenant. If
Landlord so consents, before commencement of any such work or delivery of any
materials into the Premises or the Building, Tenant shall furnish to Landlord
for approval; architectural plans and specifications, names and addresses of all
contractors, contracts, necessary permits and licenses, certificates of
insurance and instruments of indemnification against any and all claims, costs,

all in such form and amount as may be reasonably satisfactory to Landlord. In
addition, prior to commencement of any such work or delivery of any materials
into the Premises, Tenant shall provide Landlord with evidence reasonably
satisfactory to Landlord of Tenant's ability to pay for such work and materials
in full. Tenant agrees to hold Landlord, (Building Manager - agent for the

the cost of all such work. Upon completion of such work, Tenant shall furnish
Landlord with contractor's affidavits and full and final waivers of lien and
receipted bills covering all labor and materials expended. All such work shall

requirements, ordinances and rules (including the Board of Fire Underwriters),
and all requirements of applicable insurance companies. All such work shall be
done in a good and workmanlike manner and with the use of good grades of
materials including fire protection grades equivalent with those of the
Building. Tenant shall permit Landlord, if Landlord so desires, to supervise
construction operations in connection with such work; provided, however, that
such supervision or right to supervise by Landlord and the approval or
disapproval of the plans and specifications for such work in any situation shall
not constitute any warranty by Landlord to Tenant of the adequacy of the design,
workmanship or quality of such work or materials for Tenant's intended use or
impose any liability upon Landlord in connection with their performance of such
work. All structural alterations, improvements, additions and installations to
or on the Premises shall (subject to Article 13) become part of the Premises at
the time of their installation and shall remain in the Premises at the
expiration or termination of this Lease or termination of Tenant's right to
possession of the Premises, without compensation or credit to Tenant.

Landlord's consent for decorative alterations such as installation of wall
coverings, hanging or paintings, prints and other wall hangings, painting of
walls or similar alterations affecting only the interior of the Premises.

                                                                         Page 7

laborer or supplier of any other lien to be filed against the Complex, the
Building, the Common Areas, the land which comprises the Complex, the
Premises,or any part of such property arising out of work performed, or alleged
to have been performed by, or at the direction of, or on behalf of Tenant. If
any such lien or claim for lien is filed, Tenant shall within five (5) days
after such filing either have such lien or claim for lien released of record or
shall deliver to Landlord a bond or other security in form, consent, amount and
issued by a company reasonably satisfactory to Landlord indemnifying Landlord,
Manager and others designated by Landlord against all costs and liabilities
resulting from such lien or claim for lien and the foreclosure or attempted
foreclosure thereof. If Tenant fails to have such lien or claim for lien so
released or to deliver such bond to Landlord, Landlord, without investigating
the validity of such lien, may pay or discharge the same and Tenant shall
reimburse Landlord upon demand for the amount so paid by Landlord, including
Landlord's expenses and attorney's fees.

                      11. WAIVER OF CLAIMS AND INDEMNITY

act or omission to the extent actually paid by the proceeds of insurance
obtained and maintained under this Lease Agreement by Landlord in connection
with the Building. Landlord shall cause its policy or policies of insurance to
contain effective waivers of subrogation for the benefit of Tenant.

      B. Landlord and the Manager shall not be responsible or liable to Tenant

<PAGE>   14
                             12. EVENTS OF DEFAULT

this Lease: (1) Tenant fails to pay any installment of Rent when due or within
five (5) days thereafter; (2) Tenant fails to observe or perform any of the
other covenants, conditions or provisions of this Lease or under the Work Letter
to be observed or performed by Tenant and fails to cure such default within
fifteen (15) days after written notice to Tenant; provided, however, that if the
nature of Tenant's default is such that more than fifteen (15) days are
reasonably required for its cure, then Tenant shall not be deemed to be in
default if Tenant commences such cure within said fifteen (15) days and
thereafter diligently pursues such cure to completion; (3) the interest of
Tenant in this Lease is levied upon under execution or other legal process; (4)
a petition is filed by or against Tenant to declare Tenant bankrupt or seeking a

Tenant; (5) Tenant is declared insolvent by law or any assignment of Tenant's
property is made for the benefit of creditors; (6) a receiver is appointed for

12.02     LANDLORD'S REMEDIES

     Upon the occurrence of an event of default by Tenant under this Lease,
Landlord, at its option, without further notice or demand to Tenant, may in
addition to all other rights and remedies provided in this Lease, at law or in
equity:

     A.   Terminate this Lease and Tenant's right of possession of the Premises,
and at Landlord's option, discontinue any or all services set forth in Paragraph
5.01 and 9.01, and recover all damages to which Landlord is entitled under law,
specifically including, without limitation, all Landlord's expenses of
reletting (including repairs, alterations, improvements, additions, decorations,
legal fees and brokerage commissions).

     B.   Terminate Tenant's right of possession of the Premises without
terminating this Lease, in which event Landlord may, but shall not be obligated
to, relet the Premises, or any part thereof for the account of Tenant, for such
rent and upon such terms and conditions as are acceptable to Landlord. For
purposes of such reletting, Landlord is authorized to redecorate, repair, alter
and improve the Premises to the extent reasonably necessary. Until Landlord does
relet the Premises, Tenant shall pay Landlord monthly on the first day of each
month during the period that Tenant's right of possession is terminated, a sum
equal to the amount of Rent due under this Lease for such month (less any amount
which Landlord could have realized if Landlord relet the premises to a
reputable, credit-worthy substitute tenant procured by Tenant and presented to
Landlord in writing which substitute


                                                                          Page 9
<PAGE>   15
tenant was ready, willing and able to lease to the form of this Lease). If
and when the Premises are relet and a sufficient sum is not realized from such
reletting after payment of all Landlord's expenses of reletting (including
repairs, alterations, improvements, additions, decorations, legal fees and
brokerage commissions) to satisfy the payment of Rent due under this Lease for
any month, Tenant shall pay Landlord any such deficiency monthly upon demand.
Tenant agrees that Landlord may file suit to recover any sums due to Landlord
under this section from time to time and that such suit or recovery of any
amount due Landlord shall not be any defense to any subsequent action brought
for any amount not previously reduced to judgment in favor of Landlord. If
Landlord elects to terminate Tenant's right to possession only without
terminating this Lease, Landlord may, at its option, enter into the Premises,
remove Tenant's signs and other evidences of tenancy, and take and hold
possession thereof, as stated in Article 13; provided, however, that such entry
and possession shall not terminate this Lease or release Tenant, in whole or in
part, from Tenant's obligation to pay the Rent reserved hereunder for the full
Term or from any other obligation of Tenant under this Lease.

     C.  In the event a petition is filed by or against Tenant seeking a plan
or reorganization or arrangement under the Bankruptcy Code, Landlord and
Tenant agree, to the extent permitted by law, that the trustee in bankruptcy
shall determine within sixty (60) days after commencement of the case, whether
to assume or reject this Lease.

     D.  To the extent permitted by law, declare the entire balance of rent for
the remainder of the term of this Lease as due payable in full, and Landlord
shall have a lien on all property and fixtures of Tenant in or on the Premises
to secure the payment of all sums due.

     E.  Pursue any other remedy now or hereafter available to Landlord under
the laws or judicial decisions of the state wherein the Premises are located.

12.03  ATTORNEY'S FEES

     If the Tenant is finally determined to be in default hereunder, Tenant
shall pay, upon demand, all costs and expenses including reasonable attorneys'
fees, incurred by Landlord in enforcing Tenant's obligations under this Lease,
and the Work Letter or resulting from Tenant's default under this Lease.

                           13. SURRENDER OF PREMISES

     Upon the expiration or termination of this Lease or termination of Tenant's
right of possession of the Premises, Tenant shall surrender and vacate the
Premises immediately and deliver possession thereof to Landlord in a clean,
good and tenantable condition, ordinary wear, tear and aging excepted. Upon any
termination which occurs other than by reasons of Tenant's default, Tenant
shall be entitled to remove from the Premises all unattached and movable trade
fixtures and personal property of Tenant without credit or compensation from
Landlord, provided Tenant immediately shall repair all damage resulting from
such removal and shall restore the Premises to a tenantable condition, ordinary
wear, tear and aging excepted. In the event possession of the Premises is not
immediately delivered to Landlord or if Tenant shall fail to remove any
unattached and movable trade fixtures and personal property which may be
removed from the Premises by Tenant but which are not so removed upon the
vacancy of the Premises shall be conclusively presumed to have been abandoned
by Tenant and title to such property shall pass to Landlord without any
payment or credit and Landlord may, at its option and at Tenant's expense,
store and/or dispose of such property.


                                                                         Page 10


<PAGE>   16
                               14.  HOLDING OVER

     Tenant shall pay Landlord 150% of the Adjusted Monthly Base Rent then
applicable for each month or partial month during which Tenant retains
possession of the Premises, or any part of the Premises, after the expiration or
termination of this Lease, or the termination of Tenant's right of possession of
the Premises. In addition, Tenant shall indemnify Landlord against all
liabilities and damages sustained by Landlord by reason of such retention of
possession. The provisions of this Article shall not constitute a waiver by
Landlord of any re-entry rights of Landlord available under this Lease or by
law. If Tenant retains possession of the Premises, or any part of the Premises,
for thirty (30) days after the expiration or termination of this Lease, then at
the sole option of Landlord expressed by written notice to Tenant, but not
otherwise, such holding over shall constitute a renewal of this Lease for a
period of month to month on the same terms and conditions and at 150% of the
Adjusted Monthly Rent then applicable.

                     15.  DAMAGE BY FIRE OR OTHER CASUALTY

15.01  SUBSTANTIAL UNTENANTABILITY

     If either the Premises, the Building or the Complex is rendered
substantially untenantable by fire or other casualty, Landlord may elect by
giving Tenant written notice within ninety (90) days after the date of said
fire or casualty, either to: (1) terminate this Lease as of the date of the
fire or other casualty; or (2) proceed to repair or restore the Premises, the
Building or the Complex (other than leasehold improvements and personal property
installed by Tenant), to substantially the same condition as existed
immediately prior to such fire or casualty.

     If Landlord elects to proceed pursuant to subsection (2) above, Landlord's
notice shall contain Landlord's reasonable estimate of the time required to
substantially complete such repair or restoration. If such estimate indicates
that the time so required will exceed one hundred twenty (120) days from the
date of the casualty, then Tenant shall have the right to terminate this Lease
as of the date of such casualty by giving written notice to Landlord not later
than thirty (30) days after the date of the Landlord's notice. If Landlord's
estimate indicates that the repair or restoration can be substantially completed
within one hundred twenty (120) days, or if Tenant fails to exercise its said
right to terminate this Lease, this Lease shall remain in force and effect.

15.02  INSUBSTANTIAL UNTENANTABILITY

     If either the Premises, the Building or the Complex is damaged by fire or
other casualty but is not rendered substantially untenantable, then Landlord
shall diligently proceed to repair and restore the damaged portions thereof,
other than the leasehold improvements and personal property installed by Tenant,
to substantially the same condition as existed immediately prior to such fire or
casualty, unless such damage occurs during the last twelve (12) months of the
Term, in which event Landlord shall have the right to terminate this Lease as of
the date of such fire or other casualty by giving written notice to Tenant
within thirty (30) days after the date of such fire or other casualty.

15.03  RENT ABATEMENT

     If all or any part of the Premises are damaged by fire or other casualty
and this Lease is not terminated, Adjusted Monthly Base Rent shall abate for all
or that part of the Premises which are untenantable on a per diem and
proportionate area basis from the date of the fire or other casualty until
Landlord has substantially completed the repair and restoration work in the
Premises which it is required to perform, provided, that as a result of such
fire or other casualty, Tenant does not occupy the portion of the Premises which
are untenantable during such period.


                                                                         Page 11
<PAGE>   17

                               16. EMINENT DOMAIN

16.01  SUBSTANTIAL TAKING

       If all or any part of the Premises, the Building or the Complex is
permanently taken or condemned by any competent authority for any public use or
purpose (including a deed given in lieu of condemnation), which renders the
Premises substantially untenantable, this Lease shall terminate as of the date
title vests in such authority, and Adjusted Monthly Base Rent shall be
apportioned as of such date.

16.02  INSUBSTANTIAL TAKING

       If any part of the Premises, the Building or the Complex is taken or
condemned for any public use or purpose (including a deed given in lieu of
condemnation) and this Lease is not terminated pursuant to 16.01, Adjusted
Monthly Base Rent shall be reduced for the period of such taking by an amount
which bears the same ratio to Adjusted Monthly Base Rent then in effect as the
number of square feet of Rentable Area in the Premises so taken or condemned,
if any, bears to the number of square feet of Rentable Area specified in 1.01I.
Landlord, upon receipt and to the extent of the award in condemnation or
proceeds of sale, shall make necessary repairs and restorations (exclusive of
leasehold improvements and personal property installed by Tenant) to restore
the Premises remaining to as near its former condition as circumstances will
permit, and to the Building and Complex to the extent necessary to constitute
the portion of same not so taken or condemned as a complete architectural unit.
On the event of any taking or condemnation described in this Section 16.02, the
Rentable Area of the Premises stated in 1.01I and the Rentable Area of the
Complex as specified in this Lease, shall be reduced, respectively, for all
purposes under this Lease by the number of square feet of Rentable Area of the
Premises, if any, and the Complex, if any, so taken or condemned as determined
and certified by an independent professional architect selected by Landlord.

16.03  COMPENSATION

       Landlord shall be entitled to receive the entire price or award from any
such sale, taking or condemnation without any payment to Tenant, and Tenant
hereby assigns to Landlord Tenant's interest, if any, in such award; provided,
however, Tenant shall have the right separately to pursue against the condemning
authority an award in respect of the loss, if any, to leasehold improvements
paid for by Tenant without any credit or allowance from Landlord. Under no
circumstances shall the Tenant seek or be entitled to any compensation for the
value of its leasehold estate.

                            17.  TENANT'S INSURANCE

       Tenant, at its expense, shall maintain in force during the Term:


                                                                         Page 12

     A. comprehensive general public liability insurance, which shall include
coverage for contractual liability and tenant's legal liability, including
personal injury (including death) and property damage, all on an occurrence
basis with respect to the business carried on in or from the Premises and
Tenant's use and occupancy of the Premises with coverage for any one occurrence
or claim of not less than $1,000,000 or such other amount as Landlord may
reasonably require.

     8. fire and extended coverage insurance for the replacement value of
Tenant's property (including fixtures, leasehold improvements and equipment)
located in the Premises and such other insurance against such other perils and
in such amounts as Landlord may from time to time reasonably require upon not
less than ninety (90) days' prior written notice, such requirements to be made
on the basis that the required insurance is customary at the time for prudent
tenants of properties similar to the Complex in the area of the city stated in
1.01A.

     All insurance required to be maintained by Tenant shall be on terms and
with insurers reasonably acceptable to Landlord. Each policy shall contain a
waiver by the insurer of any rights of subrogation or indemnity or any other
claim to which the insurer might otherwise be entitled as provided in Section
11.03 and shall also contain an undertaking by the insurer that no material
change adverse to Landlord or Tenant will be made, and the policy will not
lapse or be canceled except after not less than thirty (30) days prior written
notice to Landlord of the intended change, lapse or cancellation. Tenant shall
furnish to Landlord, if and whenever requested by it, certificates or other
evidences acceptable to Landlord as to the insurance from time to time
maintained by Tenant and the renewal or continuation in force of such insurance.


                           18.  RULES AND REGULATIONS

     Tenant agrees for itself and for its subtenants, employees, agents, and

comparable index reflecting changes in the cost of living or purchasing power of
the consumer dollar published by any other governmental agency, bank or other
financial institution, or any recognized authority.


                                                                         Page 14

Landlord for the purpose of reducing Operating Costs or which may be required

of such costs over the useful like thereof; and (9) replacements other than as
a result of obsolescence.

     F. "Operating Expense Base" shall mean the average Operating Costs per
square foot of rentable space in the Premises stated in 1.01I hereof during the

or used in connection therewith (including any rental or similar taxes levied in
lieu of or in addition to general real and/or personal property taxes). For
purposes hereof, Taxes for any year shall be Taxes which are due for payment or
paid in that year, rather than Taxes which are assessed or become a lien during
such year. There shall be included in Taxes for any year the amount of all fees,

defined, such substituted taxes or assessment shall be included in the Taxes.

22.02 CPI ADJUSTMENT TO MONTHLY BASE RENT

      Effective as of each Adjustment Date, Monthly Base Rent shall be increased

Monthly Base Rent increase in account of the Consumer Price Index exceed four
percent (4%) per annum. compounded.


                                                                         Page 15

all controllable expenses which shall not include real estate taxes,
insurance, utilities and all other contracts subject to labor union and/or
minimum wage, i.e. janitorial, landscaping.

22.04    PROJECTIONS

         For purposes of calculating Operating Costs for any Adjustment Year,
Landlord may make reasonable estimates, forecasts or projections (collectively,
the "Projections") of Operating Costs for such Adjustment year. Not less than
ten (10) days prior to each Adjustment Date, Landlord shall deliver to Tenant a
written statement setting forth the Projections of Operating Costs for the
Adjustment Year in which such Adjustment Date occurs and providing a
calculation of the increase in installments of Monthly Base Rent to become
effective as of said Adjustment Date; provided, however, that the failure of
Landlord to provide any such statement shall not relieve Tenant from its
obligation to continue to pay Adjusted Monthly Base Rent at the rate then in
effect under this Lease, and if and when Tenant receives such statement from
Landlord, Tenant shall pay any increases in Monthly Base Rent reflected thereby
effective retroactively to the most recently preceding Adjustment Date.

22.05    READJUSTMENTS

         On or about April 1st following the end of each Adjustment Year, or at
such later time as Landlord shall be able to determine the actual amounts of
Operating Costs for the Adjustment Year last ended adjusted in accordance with
this Section, Landlord shall notify Tenant in writing of such actual amounts.
If such actual amounts exceed the Projections for such Adjustment Year, the
Tenant shall, within thirty (30) days after the date of such written notice
from Landlord, pay to Landlord its proportionate share of the excess based on
the Net Rentable Area of the Premises as compared to the total rentable office
area. The obligation to make such payments shall survive the expiration or
earlier termination of the Term. If the total Adjusted Monthly Base Rent paid
by Tenant during such Adjustment Year exceeds the amount thereof payable for
such year based upon actual Operating Costs for such Adjustment Year, then
Landlord shall credit such excess to installments of Adjusted Monthly Base Rent
payable after the date of Landlord's notice until such excess has been
exhausted, or if this Lease shall expire prior to full application of such
excess, Landlord shall pay to Tenant the balance thereof not theretofor applied
against Rent. No interest or penalties shall accrue on any amounts which
Landlord is obligated to credit or to pay Tenant by reason of this Section.
Notwithstanding any provision hereof to the contrary, in no event shall there
be any readjustment as herein provided such that the Adjusted Monthly Base Rent
shall be less than the initial Monthly Base Rent as specified in 1.01H
hereof.

22.06    PARTIAL OCCUPANCY

         For purposes of determining adjustments and readjustments to
installments of Monthly Base Rent for any Adjustment Year in which less than
ninety-five percent (95%) of the rentable area of the Building is occupied by
tenants, the amount of Taxes and Operating Expenses for such Adjustment Year
shall be increased to the amount that would have been payable had there been at
least ninety-five percent (95%) occupancy in the Building during such
Adjustment Year.


                                                                        Page 16

22.07    BOOKS AND RECORDS

         Landlord shall maintain books and records showing Operating Costs in
accordance with sound accounting and management practices and shall retain such
books and records for a period of one (1) year after the end of each calendar
year during which such operational costs were paid or incurred. The books and
records shall be available to Tenant for inspection during normal business
hours upon prior reasonable notice.

                            23. REAL ESTATE BROKERS

         Tenant represents that, except for the broker, if any, setforth in
1.01L hereof as Tenant's Broker, Tenant has not dealt with any real estate

person initiated or participated in the negotiation of this Lease, or showed
the Premises to Tenant. Tenant agrees to indemnify and hold harmless Landlord
and the Manager from and against any and all liabilities and claims for
commissions and fees arising out of a breach of the foregoing representation.
Landlord shall only be responsible for the payment of all commissions to the
broker, if any, specified in this Article 23, based upon the leasing commission
policy of Landlord applicable to the Complex as of the date of this Lease.

                        24. SUBORDINATION AND ATTORNMENT

24.01    SUBORDINATION

         This Lease and the rights of Tenant hereunder are expressly subject

hereafter existing encumbering the Complex, or any part thereof, and all

mortgage, and to all advances made or hereafter to be made upon the security of
said mortgage. Tenant agrees to execute and deliver such further instruments
subordinating this Lease to the Lien of any such mortgage as may be requested

recognize such mortgagee or purchaser, in foreclosure as Tenant's Landlord under
this Lease. Tenant agrees to execute and deliver at any time upon reasonable

         This Lease and the Exhibits attached hereto contain the entire
agreement between Landlord and Tenant concerning the Premises and there are no
other agreements, either oral or written. Neither Landlord nor any agent of

the Premises, or the Building of which the Premises is a part, or the Complex
in which the Building is located, or the use of any amenities or facilities,
except as herein expressly set forth. Any agreement hereinafter made shall be
ineffective to change, waive, modify, discharge or terminate it in whole or in
part unless such agreement is in writing and signed by the party against whom
enforcement of the change, waiver, modifications, discharge or termination is
sought.

26.03    NO OPTION

         The execution of the Lease by Tenant and delivery of same to Landlord
or Manager does not constitute a reservation of or option for the Premises or
an agreement to enter into a Lease and this Lease shall become effective only
if and when Landlord executes and delivers same to Tenant; provided, however,
the execution and delivery by Tenant of this Lease to Landlord or the Manager
shall constitute an irrevocable offer by Tenant to lease the Premises on the
terms and conditions herein contained, which offer may not be withdrawn or
revoked for thirty (30) days after such execution and delivery.

26.04    ACCORD AND SATISFACTION

         No payment by Tenant or receipt by Landlord of a lesser amount than
any installment or payment of Rent due shall be deemed to be other than on

letter accompanying a check or payment of Rent shall 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 installment or payment of
rent or pursue any other remedies available to Landlord. No receipt of money by
Landlord from Tenant after the termination of this Lease or Tenant's right of
possession of the Premises shall reinstate, continue or extend the Term.
Landlord may apply any such payment to any obligation of Tenant to Landlord
then outstanding, in Landlord's sole discretion.

26.06    FORCE MAJEURE

         Neither party hereto shall be deemed in default with respect to any of
the terms, covenants and conditions of this Lease, if such party fails to
timely perform same and such failure is due in whole or in part to any strike
lockout, labor trouble (whether legal or illegal), civil disorder, inability to
procure materials, failure of power, restrictive governmental laws and
regulations, riots, insurrections, war, fuel shortages, accidents, casualties,
Acts of God, acts caused directly or indirectly by the other party (or such
other party's agents, employees or invitees) or any other cause beyond the
commercially reasonable control of the non-performing party; provided, however,
that nothing herein shall excuse Tenant's failure to pay Adjusted Monthly Rent
or any other charges due to Landlord hereunder except as specifically provided
herein.

26.07    CAPTIONS

         The Article and Section captions in this lease are inserted only as a

after the expiration of any grace period elsewhere under this Lease or the Work
Letter expressly granted to Tenant for the performance of such duty, to perform
such duty on behalf and at the expense of Tenant without further prior notice
to Tenant, and all sums expended or expenses incurred by Landlord in performing
such duty shall be deemed to be additional Rent under this Lease and shall be
due and payable upon demand by Landlord.

26.11    RELATIONSHIPS

         The relationship between Landlord and Tenant is that of landlord and
tenant and nothing herein shall be construed to give rise to any other
relationships including, without limitation, a creditor and debtor
relationship.

26.12    INVALIDITY

         If any term(s), condition(s), covenant(s), clause(s) or provision(s)
herein contained shall operate or would prospectively operate to invalidate

clause(s), and provision(s) shall be held for naught as though not herein

                                                                        Page 19

26.13    LIMITATION OF LANDLORD'S LIABILITY

         Anything contained in this Lease to the contrary notwithstanding,

for any default or breach by Landlord of any of its obligations under this
Lease, subject, however, to the prior rights of any ground or underlying
landlord or the holder of any mortgage covering the Building or of Landlord's
interest therein. No other assets of the Landlord shall be subject to levy,
execution or other judicial process for the satisfaction of Tenant's claim.
These provisions shall not be deemed, construed or interpreted to be or
constitute an agreement, express or implied, between Landlord and Tenant that
the Landlord's interest hereunder and in the Building shall be subject to
impressment or an equitable lien or otherwise. Nothing herein contained shall
be construed to limit any right of injunction against the Landlord, where
appropriate.

officers, agents and employees, from and against any and all claims, damages,
expenses, penalties, liability and costs, resulting or arising from a breach of
the covenant contained in the paragraph above.

         The provisions of this Section 26.14 shall survive the expiration or

26.15    TRANSFER OF LANDLORD'S INTEREST

         In the event of the sale, assignment or transfer by Landlord of its
interest in the Building or in this Lease (other than a collateral assignment
to secure a debt of Landlord) to a successor in interest who expressly assumes
the obligations of Landlord hereunder, Landlord shall thereupon be released or
discharged from all of its covenants and obligations hereunder, except such
obligations as shall have accrued prior to any such sale, assignment or
transfer; and tenant agrees to look solely to such successor in interest of
Landlord for performance of such obligations. Any security given by Tenant to
Landlord to secure performance by Tenant of its obligations hereunder may be
assigned by


                                                                        Page 20

<PAGE>   26

Landlord to such successor in interest of Landlord; and, upon acknowledgment by
such successor of receipt of such security and its express assumption of the
obligation to account to Tenant for such security in accordance with the terms
of the Lease, Landlord shall thereby be discharged of any further obligation
relating thereto. Landlord's assignment of the Lease or of any or all of its
rights herein shall in on manner affect Tenant's obligations hereunder. Tenant
shall thereafter attorn and look to such assignee, as Landlord, provided Tenant
has first received written notice of such assignment of Landlord's interest.
Landlord shall have the right to freely sell, assign or otherwise transfer its
interest in the Building and/or this Lease.

26.16

          It is understood that Landlord is subject to the Employee Retirement
Income Security Act ("ERISA") and has furnished to Tenant a list of individuals
and entities transactions with which might result in a prohibited transaction
under ERISA or would otherwise cause a breach of an ERISA related requirement.
Tenant hereby warrants and represents that Tenant is not related to or
affiliated with any person or entity shown on a list to be furnished by
Landlord such that Tenant is a "party in interest" to such person or entity as
that term is defined in ERISA Section 3(14) and (15), a copy of which section
is attached hereto as Exhibit D, as that Section may be interpreted or amended.
Tenant agrees that each time that Landlord makes additions to such list that
Tenant will either make the warranty requested above or shall disclose to
Landlord the relationship with such party on the list that would cause Tenant
to be unable to make such warranty and representation. Tenant agrees to
indemnify and hold Landlord harmless from any cost, expense or damages which
may result from a breach of the warranty and representation made by Tenant.

26.17 RIDERS

          All Riders attached hereto and executed both by Landlord and Tenant
shall be deemed to be a part hereof and hereby incorporated herein.

          IN WITNESS WHEREOF, this Lease has been executed as of the date set
forth in 1.01D hereof.

                                   EXHIBIT "A"

                               Tenant Improvements

1. Space Planning          If, at the time this Lease is executed, a space plan
                           has not been prepared and approved by both Landlord
                           and Tenant, Tenant shall provide Landlord's space
                           planner with its space requirements in order to
                           prepare a space plan. This information should be
                           provided by September 25, 1998. Once the space plan
                           has been prepared by the space planner, and delivered
                           to Tenant, Tenant shall have five (5) days to modify,
                           if necessary, and approve the plan. Landlord shall
                           then estimate the cost of building out the space
                           pursuant to the plan and shall submit such estimate
                           to Tenant for approval. Tenant shall have seven (7)
                           days to approve the budget for the buildout of its
                           space.

                           In the event Tenant's improved space is not available
                           for occupancy by the Commencement Date stated in
                           Section 1.01F of this Lease and Tenant has met all
                           of the deadlines described above, Tenant's obligation
                           to pay rent will begin on the date the space is ready
                           for occupancy, and the rental schedule shall be
                           adjusted accordingly. However, if Tenant has not met
                           the time table described above and the space is not
                           ready for occupancy on the Commencement Date, the
                           obligation to pay rent will commence on the
                           Commencement Date.


2. Landlord's Work:        In addition to the allowance provided below, Landlord
                           shall provide building standard light fixtures (at a
                           ratio of one fixture for every 85 USF) window
                           treatments, and ceiling tile stacked on the floor,
                           ceiling grid in place, sprinkler system installed on
                           a 12 foot grid, HVAC high pressure duct and VAV boxes
                           in place for an open floor plan.

3. Landlord's Allowance:   Tenant shall pay, as "additional rent," the excess
                           cost as described below within ten days of receipt of
                           an invoice. Landlord shall have the improvements as
                           described on Tenant's Drawings, Sheet A100 by
                           Peterson Associates, dated 9-15-98 and 9-23-98
                           attached hereto constructed at Landlord's expense and
                           Tenant agrees to pay Landlord at time of occupancy
                           $78,682.00 which is Tenant's share or excess cost of
                           said improvement cost.

                              Rules and Regulations

1.       The Landlord may refuse admission to the Building outside of ordinary
business hours to any person not known to the watchman in charge or not
properly identified, and may require all persons admitted to or leaving the
Building outside of ordinary business hours to register. Any person whose
presence in the Building at any time shall, in the reasonable judgment of the
Landlord, be prejudicial to the safety, character, reputation and interest of
the Building or its Tenants may be denied access to the Building or may be
ejected therefrom. In case of invasion, riot, public excitement or other
commotion, the Landlord may prevent all access to the Building during the
continuance of the same, by closing the doors or otherwise, for the safety of
the Tenants, the Building and protection of property in the Building. The
Landlord may require any person leaving the Building with any package or other
object to exhibit a pass from the Tenant from whose Premises the package or
object is being removed, but the establishment and enforcement of such
requirement shall not impose any responsibility on the Landlord for the
protection of any Tenant against the removal of property from the Premises of
the Tenant. The Landlord shall in no way be liable to any Tenant for damages or
loss arising from the admission, exclusion or ejection of any person to or from
the Tenant's Premises or the Building under the provisions of this rule.

2.       Landlord reserves the right to exclude or expel from the building any
person who in the judgment of Landlord is intoxicated or under the influence of
liquor or drugs.

3.       Tenants shall not do or permit anything to be done in their Premises or
bring or keep anything therein which will in any way obstruct or interfere with
the rights of other tenants, or do, or permit anything to be done in their
Premises which shall, in the judgment of the Landlord or its manager, in any
other way injure or annoy them, or conflict with the laws relating to fire, or
with the regulations of the fire department or with any insurance policy upon
the Building or any part thereof or any contents therein or conflict with any of
the Rules and Ordinances of the public building or health authorities.

4.       All electrical equipment used by Tenants shall be U.L. approved.
Nothing shall be done or permitted in Tenant's Premises, and nothing shall be
brought into or kept in the Premises which would impair or interfere with any of
the Building services or the proper and economic heating, cooling, cleaning or
other servicing of the Building or the Premises.


                                                                          Page 1
<PAGE>   31


5.       Tenants shall not install or operate any steam or gas engine or boiler,
or carry on any mechanical business, in the building. The use of oil, gas or
inflammable liquids for heating, lighting or other purposes is expressly

brought into the Building. Tenants shall not use any other method of heating
than that supplied by the Landlord.

6.       Tenants shall give Landlord prompt notice of all accidents to or
defects in air-conditioning equipment, plumbing, electric facilities or any part
or appurtenance of their Premises.

7.       Tenants shall use electric, gas and any other form of energy only from
such sources of supply as is furnished in the Building.

8.       All deliveries to the Building for or by any Tenant are to be made
through the service entrance to Building as designated by Landlord, unless
special permission is granted by Landlord for the use of other Building
entrances.

9.       Furniture, equipment or supplies shall be moved in or out of the
Building as designated by Landlord, unless special permission is granted by
Landlord for the use of other Building entrances.

10.      Should any Tenant desire to place in the Building any unusually heavy
equipment, including, but not limited to, large files, safes and electronic data
processing equipment, it shall first obtain approval of the Landlord to place
such items within the Building, for the use of the Building elevators, and for
the proposed location in which such equipment is to be installed. The Landlord
shall have the power to prescribe the weight and position of any equipment that
may exceed the weight load limits of the building structure, and may further
require, at the tenant's expense, the reinforcement of any flooring on which
such equipment may be placed, and/or to have an engineering study performed to
determine such weight and position of equipment, to determine added
reinforcement required, and/or determine whether or not such equipment can be
safely placed within the Building.

11.      Tenants shall not place additional locks or bolts of any kind upon any
of the doors of their Premises and no lock on any door therein shall be changed
or altered in any respect. Duplicate keys for Tenant's Premises and toilet rooms
(if applicable) shall be procured only from Landlord, which may make a
reasonable charge therefor. Upon the termination of a Tenant's lease, all keys
of the Premises and toilet rooms shall be delivered to the Landlord.

12.      Tenants shall not leave any refuse in the public hallways or other
areas of the Building (excepting Tenant's own Premises) for disposal.

                                                                          Page 2



<PAGE>   32


13.      Landlord shall have the right to prohibit any advertising by Tenants
which, in Landlord's reasonable opinion, tends to impair the reputation of the
Building or its desirability as a building or offices; upon written notice from
the Landlord, Tenant shall refrain from or discontinue such advertising.

14.      If a Tenant employs laborers or others outside of the Building, such
Tenant shall not have its employees paid in at the Building, but shall arrange
to pay their payrolls elsewhere. Tenants shall not advertise for laborers,
giving an address at the Building.

15.      Bicycles or other vehicles shall not be permitted in the offices,
halls, corridors, lobbies and elevators of the Building, nor shall any
obstruction of sidewalks or entrances of the Building by such be permitted.

16.      The sidewalks, entries, passages, elevators and staircases shall not be
obstructed or used by Tenants, their servants, agents or visitors for any other
purpose than ingress and egress to and from the respective offices.

17.      Canvassing, soliciting and peddling in the Building is prohibited and
tenants shall cooperate to prevent the same.

18.      No animals, birds or pets (other than seeing-eye dogs) of any kind
shall be allowed in Tenant's Premises or Building.

19.      The water closets, urinals, waste lines, vents or flues of the Building

                                   EXHIBIT "E"

                                EXPANSION RIGHTS

During the original term of the Lease, if Tenant is not then in default under
this Lease, and if, at any time during the first four (4) years of the Term
of this Lease, Landlord intends to make an offer to lease any space not leased
and vacant on the fourth (4th) floor of the Building to a third party, Landlord
shall first give Tenant written notice of the square footage, availability date
and terms of the offer Landlord intends to make, including, without limitation,
the tenant improvement allowance, if any, Landlord intends to offer. Tenant
shall have ten (10) business days after receipt of any such notice to elect to
lease all such space on the terms offered. If Tenant rejects any such offer, or
fails to respond to any such offer within said period, Landlord shall be free to
lease the offered space upon substantially the same terms and conditions as
those contained in Landlord's notice. A reduction in the rental terms of ten
percent (10%) or less shall not be deemed a substantial change in the terms. If
Landlord substantially changes the terms and conditions on which Landlord is
offering any such space, Landlord shall resubmit such offer to Tenant and Tenant
shall have ten (10) business days in which to accept any new offer. If Tenant
accepts any such offer, the space offered shall be added to the Premises at the
rental set forth in Landlord's offer on the same terms and conditions set forth
in Landlord's offer. In the event Tenant leases such space, Tenant's obligation
to pay Rent on such space shall commence thirty (30) days after Tenant accepts
said offer to lease space or upon delivery of said space finished as specified
in Landlord's offer whichever comes first. If Tenant rejects or fails to respond
to any such offer within the required period, Landlord may proceed to Lease
space to the other party and Tenant shall have waived its right to lease such
space until it next comes vacant and available.

In addition to Tenant's right of first offer set forth above, within 48 months
after the Lease Commencement Date, Tenant shall also have the right to lease any
or all of the vacant space on the fourth (4th) floor of the Building by giving
Landlord written notice of its desire to lease such vacant/unleased additional
space, provided however, that once Landlord has delivered written notice
pursuant to the preceding paragraphs, the terms of the preceding paragraph shall
apply with respect to such space. Such notice from Tenant for additional space
shall specify the space to be leased and the proposed date on which Tenant shall
begin leasing such additional space; provided the additional space being leased
by Tenant is configured to leave any unleased space on the floor in a
configuration that is usable and leaseable without discount and has
proportionately the same amount of exterior glass to interior space as the space
being leased and the Rent shall commence within sixty (60) days of said notice
for said additional space notice. The rental rate for the additional space shall
be at the then current rental rates for comparable space in the Building, except
if Tenant exercises the right of first offer within the first six months after
the Commencement Date of the Lease, then the rental rate for said additional
space shall be the same square foot rental rate as the rate used for the
original 16,660 RSF premises. Based on the number of months remaining on the
original lease term, Landlord shall contribute $.25 per month per usable square
foot toward tenant's required upfit or build out cost for said additional leased
space. Ex.: Tenant leases 2,000 usable square feet with three years remaining on
the lease term, Landlord would contribute 2,000 x $.25 x 36 mo. = $18,000 or
$9.00/USF. Except as otherwise set forth in this Exhibit "E", the terms set
forth in this Lease shall apply to any additional space on the fourth (4th)
floor of the Building.

                                 RENEWAL OPTION

Tenant shall have one (1) option to renew the Term of this Lease for a five (5)
year period. Such option is conditioned upon Tenant's not being in default under
this Lease at that time. Tenant shall exercise the option by written notice to
Landlord given on or before the date six (6) months before the commencement of
the renewal period in question. The option shall terminate if notice is not
timely given by Tenant. The option period shall commence upon the expiration of
the initial Term. All references to the "Term" of this Lease shall, unless the
context shall clearly indicate a different meaning, be deemed to include a
reference to the initial Term of this Lease as renewed as herein provided. Such
renewal shall be on the same terms and conditions as are set forth herein except
that Adjusted Monthly Base Rent at the commencement of each renewal period shall
be the then existing fair market rental for the Premises and the Operating
Expense Base shall be the Operating Cost per rentable square foot for the year
in which the renewal period commences. "Fair Market Rental" shall mean the fair
market rental applicable to commercial office space of size and quality similar
to the Premises in the South Park area of Charlotte, North Carolina, in the
proximity of the Building then being paid by tenants exercising a renewal or
extension of office space taking into consideration all terms, conditions,
considerations and concessions being offered by landlords for renewals and
extensions of such comparable space and the absence of those considerations and
concessions and reduced or absent leasing commissions that would otherwise be
offered and incurred were this Lease a new lease rather than an extension of an
existing lease. Fair Market Rental shall be determined as follows: upon
Landlord's receipt of Tenant's notice of exercise of the renewal option, the
parties shall attempt to agree on the Rent to be applicable during the renewal
period in question, but if the parties cannot agree on the Rent to be applicable
during said renewal period within thirty (30) days after Tenant's notice, then
within twenty (20) days after the expiration of said 30-day period if Tenant has
not rescinded its notice of exercise of the renewal option due to the inability
of the parties to agree on the Fair Market Rental, Landlord and Tenant shall
each appoint an appraiser and the two appraisers so appointed shall attempt to
agree upon the Fair Market Rental for the Premises. If within thirty (30) days
after the date of appointment of the last appraiser appointed hereunder the two
appraisers cannot agree upon the Fair Market Rental, then within five (5) days
after the expiration of such 30-day period both appraisers shall submit their
written opinion of such Fair Market Rental to Landlord and Tenant, and the two
appraisers shall then select a third appraiser. The third appraiser shall
submit his opinion as the Fair Market Rental for the Premises to both Landlord
and Tenant within thirty (30) days following his appointment. If the rental as
set by the third appraiser is an amount between the rental as set by the two
other appraisers, then his opinion shall be final and binding on the parties
hereto. If the rental as set by the third appraiser is lower than the lower
rental as set by the other two appraisers, or higher than the higher rental as
set by the other two appraisers, the rental as set by the third appraiser shall
be disregarded totally, and the applicable rental shall be the amount computed
by averaging the rental as set by the first two appraisers. If the two
appraisers fail to agree upon the third appraiser within five (5) days after the
expiration of the 30-day period they have to agree upon the rental, then the
third appraiser shall be selected by the highest ranking officer of the American
Arbitration Association's office in Charlotte, North Carolina. All appraisals
shall be expressed as a rental per square foot. Each appraiser shall have an
M.A.I. and/or S.R.P.A. designation, be licensed in the State of North Carolina
(if North Carolina licenses appraisers), be disinterested and be experienced
with the appraisal of rental property in the South Park area of Charlotte, North
Carolina. Each party shall bear the fees and expenses of the appraiser appointed
by it, and the parties shall equally share the fees and expenses of the third
appraiser. Upon Tenant exercising this renewal option, Landlord shall provide a
refurbishment allowance sufficient to cover all carpet cleaning, painting and
any necessary refurbishments required in the Premises. Such allowance shall be
taken into account in determining the Fair Market Rental for the Premises and
shall be based on the current market for refurbishment allowances.
