installment.

4.      USE. The Premises shall be used only for general office purposes,
        ---
computer and telecommunications equipment room (including, without limitation,
collocation services to Tenant's customers) and for no other use or purpose
without the prior written consent of Landlord. Except as otherwise permitted in
this Lease, outside storage, including without limitation, trucks and other
vehicles, is prohibited without Landlord's prior written consent, which consent
shall not be unreasonably withheld, conditioned or delayed. Tenant shall at its
own cost and expense obtain any and all other licenses and permits necessary for
any such use. Landlord represents to the best of its knowledge and belief that
applicable governmental laws, ordinances and regulations permit the use of the
Premises for general offices and computer and telecommunications equipment room,
and that the Premises is in compliance with all such applicable laws, ordinances
and regulations. During the Demised Term, Landlord shall comply with all such
applicable governmental laws, ordinances and regulations regarding the Premises,
the Building and the Land except to the extent Tenant must comply under this
Paragraph. Tenant shall comply with all governmental laws, ordinances and
regulations applicable to its specific use of the Premises, and shall promptly
comply with all governmental orders and directives for the correction,
prevention and abatement of nuisances caused by Tenant or its agents, employees,
customers or invitees in or upon, or connected with, the Premises, all at
Tenant's sole expense. Tenant shall not permit any objectionable or unpleasant
odors, smoke, dust, gas, noise or vibrations to emanate from the Premises, nor
take any other action which would constitute a nuisance. Without Landlord's
prior written consent, Tenant shall not receive, store or otherwise handle any
product, material or merchandise which is explosive or highly inflammable.
Tenant will not permit the Premises to be used for any purpose or in any manner
(including, without limitation, any method of storage) which would render the
insurance thereon void or the insurance risk more hazardous (unless Tenant
agrees to pay any increased premiums) or cause the State Board of Insurance or
other insurance authority to disallow any sprinkler credits. Tenant shall not
use the Premises for the generation, storage, transportation or disposal of
dangerous, toxic or hazardous materials, chemicals, wastes or similar
substances; provided, however,

                                       2
<PAGE>

that Tenant may use materials or substances in small quantities as are typically
used in an office building and in a telecommunications and computer equipment
room, and materials required for cleaning and maintaining computer and
telecommunications equipment and batteries and fuel for Tenant's equipment and
fixtures.

5.   TAXES.
     -----

     (a) Landlord agrees to pay before delinquency, all taxes, assessments and
governmental charges of any kind and nature whatsoever (hereinafter collectively
referred to as "taxes") lawfully levied or assessed against the Premises;
provided, however, that the amount of taxes to be paid by Landlord hereunder for
the Premises shall be proportionately reimbursed to it by Tenant, pursuant to
Paragraph 8.

     (b) If at any time during the term of this Lease, the present method of
taxation shall be changed so that in lieu of the whole or any part of any taxes,
assessments or governmental charged, levied, assessed or imposed on real estate
and the improvements thereon, there shall be charged, levied, assessed or
imposed on Landlord a capital levy or other tax directly on the rents received
therefrom and/or a franchise tax, assessment, levy or charge measured by or
based, in whole or in part, upon such rents for the present or any future
building or buildings on the Premises, then all such taxes, assessments, levies
or charges, or the part thereof so measured or based, shall be deemed to be
included within the term "taxes" for the purposes hereof.

          (1) Landlord shall have the right (but no obligation unless Tenant
     requests Landlord to do so) to employ a tax consulting firm to attempt to
     assure a fair tax burden on the building or buildings in which the Premises
     are located and grounds surrounding the Premises within the applicable tax
     jurisdiction. Tenant shall pay to Landlord upon demand from time to time,
     as additional rent, the amount of Tenant's "proportionate share" (as
     defined in subparagraph 8(e) herein) of the cost of such service provided
     that such firm is successful in reducing the taxes, but in no event shall
     Tenant's share exceed the amount of the reduction in taxes attributable to
     Tenant unless Tenant has requested Landlord to employ such services.

          (2) Any payment to be made pursuant to this Paragraph 5 shall be
     prorated in the event any portion of the Demised Term is not within a full
     real estate tax year.

6.   LANDLORD'S REPAIRS. Landlord shall at its expense maintain only the roof,
     ------------------
foundation, the structural soundness of the exterior walls of the Premises, the
Building and the Land in good and safe working order and repair, reasonable wear
and tear excepted, and in a condition at least comparable to other first class
office buildings in the Atlanta, Georgia metropolitan area. Tenant shall repair
and pay for any damage caused by the negligence of Tenant, or Tenant's
employees, agents or invitees, or caused by Tenant's default hereunder. The term
"walls" as used herein shall not include windows, glass or plate glass, doors,
special store fronts or office entries. Tenant shall within a reasonable amount
of time give Landlord written notice of defect or need for repairs, after which
Landlord shall have reasonable opportunity to repair same or cure such defect.
So long as Landlord proceeds' with reasonable diligence to cure any defect or
perform any repairs or maintenance, Landlord's liability with respect to any
defects, repairs or maintenance for which Landlord is responsible under any of
the provisions of this Lease shall be limited to the cost of such repairs or
maintenance or the curing of such defect, unless such defect is caused by
Landlord's negligence or intentional misconduct.

7.   TENANT'S REPAIRS.
     ----------------

     (a)  Tenant shall at its own cost and expense keep and maintain all parts
of the Premises (except those for which Landlord is expressly responsible under
the terms of this Lease) in good condition, promptly making all necessary
repairs and replacements, including but not limited to, windows, glass and plate
glass, doors, any special office entry, interior walls and finish work, floors
and floor covering, heating and air conditioning systems, plumbing work and
fixtures within the Premises, interior termite and pest extermination within the

<PAGE>

     (b) Tenant shall provide Landlord with prior notice of any repair to be
undertaken by Tenant and such other information as Landlord may reasonably
request with respect to such repair, except such notice shall not be required if
immediate repair is necessary for security or safety reasons or to prevent the
disruption of services to the Premises.


8.   COMMON AREA COSTS. Tenant shall pay, as additional rent, to Landlord
     -----------------
Tenant's "proportionate share" of the reasonable cost and expense of all

limitation, the parking area leased by Landlord to third parties), including,
but not limited to the mowing of grass, maintenance of parking areas, entrances
and driveways, security lighting, landscape maintenance and irrigation, water
and sewer charges. Payment shall be made on the first day of each month based on
the projected cost of such maintenance. At the end of each year, Landlord shall

will be, at Tenant's option, either credited against the following years
payments or refunded to Tenant. Tenant shall also be responsible for all of its
janitorial and trash removal and all other expenses related directly to the
operation of Tenant's business. The books and records maintained reflecting
common area maintenance costs shall be made available for Tenant's inspection at
reasonable times.

     (ix)   Cost of service or maintenance contracts with independent
            contractors for the operation, maintenance, repair, replacement, or

     (x)    Cost of maintaining accounting books and records.

     (xi)   Costs of contractual management or administration fees and other

     (xii)  Cost of trash removal, garbage, snow and ice removal; servicing,

principles consistently applied; costs incurred because Landlord violated the

paintings, or other objects of art; costs incurred to remedy structural defects
in the original construction of the Building; any costs, fines, or penalties

or order; costs incurred to test, survey, cleanup, contain, abate, remove, or
otherwise remedy hazardous wastes or asbestos-containing materials unless the
same were in the Premises because of Tenant's negligence or intentional
misconduct; and other expenses that under generally accepted accounting
principles consistently applied would not be considered normal maintenance,
repair, management or operation expenses. Landlord shall use reasonable efforts
to keep Operating Costs at reasonable amounts while maintaining a high quality
Project.

     b.     The actual amount of additional rent payable shall be an amount
equal to the tenant's proportionate share of the Operating Costs for the
calendar year in question. "Calendar Year" shall mean any period during the
Demised Term of this Lease commencing on January 1 and ending on the next
following December 31.

     c.     At the commencement of the Demised Term and thereafter through the
end of the calendar year in which the Term commences, Tenant shall pay an
estimated amount of $2.06/sf per year or $6,041.12 per month as Tenant's
estimated additional rent. On or before December 31st of each Calendar Year
during the Demised Term, or as soon thereafter as practicable but in no event
later than March 1 of the next calendar year, Landlord shall give Tenant written
notice of its estimate of the additional rent for the next ensuing calendar
year. When the base rent shall be due and payable, Tenant

                                       5
<PAGE>

shall also pay to Landlord one-twelfth (1/12) of such estimated additional rent,
provided that if such notice is not given in December, Tenant shall continue to
pay the monthly payment based on the additional rent computed for the previous
calendar year until the month after such notice is given.

     d.     As soon as practicable after the close of each calendar year, but in
no event later than March 1 of the following calendar year, Landlord shall
deliver to Tenant a final itemized statement in reasonable detail of the
additional rent for the immediately preceding calendar year and such statement
shall be final and binding upon Landlord and Tenant, except as hereinafter
provided. If such statement shows an amount owing by Tenant that is less than
the payments actually made by the Tenant for the immediately preceding calendar
year, Tenant, at Tenant's option, shall be credited for such excess against the
next monthly payments of additional rent, or Tenant shall be entitled to a
refund of such excess. If such statement shows an amount owing by Tenant that is
more than the payments actually made by the Tenant for the immediately preceding
calendar year, Tenant shall pay the deficiency to Landlord within thirty (30)
days after delivery of the statement. Landlord shall keep and maintain records,
of all Operating Costs for a period of not less than two (2) years, which
records shall be made available to Tenant at reasonable times at Landlord's
offices for inspection and copying by Tenant or its representatives, at Tenant's
cost. If Tenant disputes any item of Operating Costs, Tenant may engage its own
accountants to verify the accuracy of the statement or the reasonableness of the
estimated Operating Costs. If Tenant's accountants determine that an error has
been made, Landlord and Tenant shall endeavor to agree upon the matter, failing
which such matter shall be submitted to an independent certified public
accountant selected by Landlord with Tenant's approval, for a determination
which will be conclusive and binding upon Landlord and Tenant. All costs
incurred by Tenant for Tenant's accountants shall be paid for by Tenant unless
an error is determined to exist pursuant to the procedure outlined above of more
than two percent (2%) of the Operating Costs, in which event Landlord shall
reimburse Tenant for such costs. If it is determined that any portion of the
Operating Costs were not properly chargeable to Tenant, then Landlord shall
promptly credit or refund, at Tenant's option, the appropriate sum to Tenant,
and Tenant's share of the Operating Costs shall be adjusted, if required.

     e.     Tenant's "proportionate share", as used in this Lease, shall mean
one hundred percent (100%).

9.   TENANT IMPROVEMENTS TO PREMISES. Tenant shall not make any alterations,
     -------------------------------
additions or improvements to the Premises, exterior or interior, without the
prior written consent of Landlord, which consent shall not be unreasonably
withheld, conditioned or delayed, except for unattached movable fixtures which
may be installed without drilling, cutting or otherwise defacing, damaging or
overloading the Premises. Except as otherwise provided in this Lease or the
Addendum attached hereto, all alterations, additions or improvements erected by
Tenant shall be and remain the property of Tenant during the term of this Lease
and Tenant shall, unless Landlord otherwise elects as provided below, remove all
alterations, additions or improvements erected by Tenant and restore the
Premises to their original condition, reasonable wear and tear and loss by
casualty excepted, by the date of termination of this Lease; provided, however,
that if Landlord so elects prior to termination of this Lease, such alterations,
additions or improvements shall become the property of Landlord as of the date
of termination of this Lease (unless Landlord and Tenant have otherwise agreed).
All construction work done by Tenant in the Premises shall be performed in a
good and workmanlike manner and in compliance with all governmental
requirements.

10.  SIGNAGE. Except as otherwise permitted in this Lease or the Addendum
     -------
attached hereto, Tenant shall not install any signs (exterior or interior)
visible from outside the Premises except with the prior written consent of
Landlord, which consent shall not be unreasonably withheld, conditioned or
delayed. Any permitted signs shall be maintained in compliance with applicable
governmental rules and regulations governing such signs. Tenant shall be
responsible to Landlord for any damage caused by the installation, use or
maintenance of said signs. Tenant agrees, upon removal of said signs, to repair
all damage (including discoloration) incidental thereto.

11.  RIGHT OF ENTRY; INSPECTION. Upon advance notice to Tenant (except in case
     --------------------------
of an emergency), and upon the terms and conditions contained in this Lease and
the Addendum attached

                                       6
<PAGE>

hereto, Landlord and Landlord's agents and representatives shall have the right
to enter and inspect the Premises at any reasonable time during business hours,
to ascertain the condition of the Premises, to make such repairs as may be
required or permitted to be made by Landlord under the terms of this Lease, or
to show the Premises to prospective purchasers or within the last six (6) months
of the Demised Term, to prospective tenants. Landlord shall have the right to
place or erect on the Premises a suitable sign indicating the Premises are
available for rent during the last six (6) months of the Demised Term.

     (a) Tenant shall give written notice to Landlord at least thirty (30) days
prior to vacating the Premises and shall arrange to meet with Landlord for a
joint inspection of the Premises prior to vacating. In the event of Tenant's
failure to give such notice or arrange joint inspection, Landlord's inspection
at or after Tenant's vacating the Premises shall, if reasonable, be conclusively
deemed correct for purposes of determining Tenant's responsibility for repairs
and restoration.

12.  UTILITIES. Landlord represents to the best of its knowledge and belief that
     ---------
water, gas, electricity and telephone service connections are available to the
Premises in a quantity and quality at least equivalent to the services provided
by other first class office buildings in the Atlanta, Georgia metropolitan
area; but Tenant shall pay for all gas, heat, light, power, telephone, sprinkler
charges and other utilities and services used in or from the Premises, together
with any taxes, penalties, surcharges or the like pertaining thereto and any
maintenance charges for utilities and shall furnish all electric light bulbs and
tubes. If any such services are not separately metered to Tenant, Tenant shall
pay Tenant's proportionate share. Landlord agrees to cooperate, and not take any
action that might interfere, with Tenant's ability to obtain any utility
services. Landlord shall in no event be liable for any interruption or failure
of utility services on the Premises so long as such interruption or failure of
utility services is not caused by Landlord or its agents; provided, however,
that if any interruption or failure of utility services to the Premises occurs,
Landlord will cooperate in any efforts to restore services.

13.  ASSIGNMENT AND SUBLETTING.
     -------------------------

     (a) Tenant shall not, directly or indirectly, have the right to assign this
Lease or to sublet the whole or any part of the Premises without the prior
written consent of Landlord, which shall not be unreasonably withheld,
conditioned or delayed. Consent to any assignment or sublease shall not be
deemed a waiver of the right of Landlord to approve or disapprove a further
assignment or subletting. Notwithstanding any permitted assignment or
subletting, except as otherwise agreed by Landlord in connection with a
permitted assignment or subletting, Tenant shall at all times remain directly,
primarily and fully responsible and liable for the payment of the rent herein
specified and for compliance with all of its other obligations under the terms,
provisions and covenants of this Lease. Upon the occurrence of an "event of
default," as hereinafter defined, if the Premises or any part thereof are then
assigned or sublet, Landlord, in addition to any other remedies herein provided,
or provided by law, may at its option collect directly from such assignee or
subtenant all rents becoming due to Tenant under such assignment or sublease and
apply such rent against any sums due to Landlord from Tenant hereunder, and no
such collection shall be construed to constitute a novation or a release of
Tenant from the further performance of Tenant's obligations hereunder.

     (b) In the event that Tenant assigns this Lease or sublets the Premises or
any part thereof, as permitted herein, and at any time receives rent and/or
other consideration which exceeds that which Tenant would at that time be
obligated to pay Landlord, Tenant shall pay to Landlord fifty percent (50%) of
the net excess in such rent as such rent is received by Tenant and fifty percent
(50%) of any other net consideration received by Tenant from such assignee or
subtenant. In addition, should Landlord agree to an assignment or sublease
agreement, Tenant will pay to Landlord on demand a sum equal to all Landlord's
costs, including reasonable attorney's fees, incurred in connection with such
assignment or transfer, all such costs not to exceed $500.00 per assignment or
transfer. If an assignment or subletting is approved, Tenant shall be entitled
to deduct from any excess proceeds described in this subparagraph 13.b. its
reasonable expenses incurred in connection with such assignment or subletting
(including, without limitation, leasing commissions, improvements made to the
Premises by Tenant for its own use and also for the transferee, costs incurred

14.  INSURANCE.
     ---------

     (a) Landlord agrees to maintain standard fire and extended coverage
insurance covering the buildings of which the Premises are a part in an amount
not less than one hundred percent (100%) of the "replacement cost" thereof as
such term is defined in the Replacement Cost Endorsement to be attached thereto,
insuring against the perils of Fire, Lightning and Extended Coverage, such
coverage and endorsements to be as defined, provided and limited in the standard
bureau forms prescribed by the insurance regulatory authority for the State in
which the Premises are situated for use by insurance companies admitted in such
state for the writing of such insurance on risks located within such state.
Subject to the provisions of Paragraph 15, such insurance shall be for the sole
benefit of Landlord and under its sole control. Landlord also agrees to maintain
comprehensive general public liability insurance with a combined single limit of
not less than $1,000,000.00.

     (b) Notwithstanding, the foregoing, Tenant shall pay, as additional rent,
to Landlord, Tenant's proportionate share of the cost of such insurance
coverage, pursuant to Paragraph 8. Any payment to be made pursuant to this
subparagraph 14.a. shall be prorated for any portion of the Demised Term which
is not a full premium period under said insurance policy.

     (c) Tenant shall, throughout the term of this Lease, at its cost and
expense, provide and keep in force a comprehensive general public liability
insurance policy with a combined single limit of not less than $1,000,000.00.
Tenant shall be solely responsible for keeping insured, to the extent Tenant
elects, its own personal property located on the Premises.

     (d) All insurance provided by Tenant as required by this subparagraph 14.b.
shall name, as additional insured, Landlord and any mortgagees or deed to secure
debt holders of the Premises, and be carried by such responsible companies and
in such form reasonably satisfactory to Landlord.

     (e) Tenant agrees to deliver to Landlord on or before the Commencement Date
the original policy of insurance required by this subparagraph 14.b. or
certificate thereof and evidence of payment of, premium. At least five (5) days
prior to the expiration of each such policy, Tenant shall deliver to Landlord
the new original policy or certificate for renewal insurance and evidence of
payment of premium.

     (f) Tenant shall not violate or knowingly permit to be violated any of the
conditions or provisions of any policy required by this subparagraph 14.b.

     (g) Each insurance policy (including renewal insurance) or certificates
thereof issued by the insurer shall contain an agreement by the insurer that
such policy shall not be canceled without at least thirty (30) days prior
written notice to Landlord, and in no event shall such policies be canceled by
Tenant without Landlord's prior written consent, unless such policies are being
replaced with new policies meeting the requirements of this paragraph 14.

     (h) Tenant and Landlord, shall cooperate in connection with the collection
of any insurance monies that may be due in the event of loss. Tenant and
Landlord shall execute and deliver such proofs or loss and other instruments
which may be required for the purpose of obtaining the recovery of any such
insurance monies.

     (i) Any insurance provided for in this Paragraph 14 may be effected by a
policy or policies of blanket insurance; provided, however, that the amount of
the total insurance allocated to the Premises shall be such as to furnish in
protection the equivalent of separate policies in the amount herein required,
and, provided further, that in all other respects, any such policy or policies
shall comply with the other provisions of this Lease. In any such case, it shall
not be necessary to deliver the original of any such blanket policy, but rather
a certified duplicate as such policy or certificate thereof.

     (j) Landlord hereby waives all claims against Tenant covered by insurance
or, if Landlord fails to carry any insurance required by this Lease, claims that
would be covered by the insurance

                                       8
<PAGE>

required to be carried under this Lease and agrees that each policy of insurance
carried by Landlord shall contain a waiver of subrogation under which Landlord's
insurers waive any claim they may have against Tenant or any person under
Tenant's control notwithstanding that the damage suffered is caused by the act,
omission, fault or want of skill of Tenant or such person.

     (k) Tenant hereby waives all claims against Landlord covered by insurance
or, if Tenant fails to carry any insurance required by this Lease, claims that
would be covered by the insurance required to be carried under this Lease and
agrees that each policy of insurance carried by Tenant shall contain a waiver of
subrogation under which Tenant's insurers waive any claim they may have against
Landlord or any person under Landlord's control notwithstanding that the damage
suffered is caused by the act, omission, fault or want of skill of Landlord or
such person.

15.  DAMAGE OR DESTRUCTION; SUBROGATION.
     ----------------------------------

     (a) If the Premises should be damaged or destroyed by fire, tornado or
other casualty, Tenant shall give immediate written notice thereof to Landlord.

     (b) If the Premises shall be totally destroyed by fire, tornado or other
casualty, or if they should be so damaged thereby that rebuilding or repairs
cannot, in Landlord's estimation, be completed within one hundred twenty (120)
days after the date upon which Landlord is notified by Tenant of such damage,
either Landlord or Tenant may terminate this Lease by written notice to the
other party whereupon all rights and obligations hereunder shall cease and
terminate, effective upon the date of the occurrence of such damage.

     (c) Subject to the foregoing, if the Premises should be damaged or
destroyed by any peril covered by the insurance required to be provided by
Landlord under subparagraph 14.a, but only if neither Landlord or Tenant has
terminated this Lease as provided under subparagraph 15(b), this Lease shall not
be terminated, and Landlord shall, at its sole cost and expense thereupon,
proceed with reasonable diligence to rebuild and repair the Premises to
substantially the condition in which they existed prior to such damage, except
that Landlord shall not be required to rebuild, repair or replace any part of
the partitions, fixtures, additions and other improvements which may have been
placed in, on or about the Premises by Tenant. If the Tenant's use and enjoyment
of the Premises for its normal business operations are materially adversely
affected, in whole or in part, following such damage, the rent payable hereunder
during the period in which Tenant's use and enjoyment of the Premises for its
normal business operations are materially adversely affected shall be abated' to
such extent as may be fair and reasonable under all of the circumstances. In the
event that Landlord should fail to complete such repairs and rebuilding within
one hundred twenty (120) days after the date upon which Landlord is notified by
Tenant of such damage, Tenant may, at its option, terminate this Lease by
delivering, written notice of termination to Landlord as Tenant's exclusive
remedy (provided that Landlord proceeded with reasonable diligence to perform
such repairs and rebuilding), whereupon all rights and obligations hereunder
shall cease and terminate.

     (d) Notwithstanding anything herein to the contrary, in the event the
holder of any indebtedness secured by a mortgage or deed to secure debt covering
the Premises requires that the insurance proceeds be applied in such
indebtedness, then Landlord shall have the right to terminate this Lease unless
Tenant agrees to pay the cost of any repairs in excess of the available
insurance proceeds by delivering written notice of termination to Tenant within
fifteen (15) days after such requirement is made by any such holder, whereupon
all rights and obligations hereunder shall cease and terminate.

     (e) Each of Landlord and Tenant hereby releases the other from any loss or
damage to property caused by fire or any other perils insured through or under
them by way of subrogation or otherwise for any loss or damage to property
caused by fire or any other perils insured in policies of insurance covering
such property or in the policies of insurance required under this Lease,
whichever is greater, even if such loss or damage shall have been caused by the
fault or negligence of the other party, or anyone for whom such party may be
responsible; provided, however, that this release shall be applicable and in
force and effect only with respect to loss or damage occurring during such times
as the

                                       9
<PAGE>

releasor's policies shall contain a clause or endorsement to the effect that any
such release shall not adversely affect or impair said policies or prejudice the
right of the releasor to recover thereunder and then only to the extent of the
insurance proceeds payable under such policies. Each of the Landlord and Tenant
agrees that it will use its best efforts to cause its insurance carriers to
include in its policies such a clause or endorsement. If extra costs in excess
of commercially reasonable rates shall be charged therefor, each party shall
advise the other thereof and of the amount of the extra costs, and the other
party, at its election, may pay the same, but shall not be obligated to do so.
If the other party declines to pay such extra costs, both parties shall be
released of their obligation to obtain the waiver.

16.  LIABILITY. Landlord shall not be liable to Tenant or Tenant's employees,
     ---------
agents, invitees, patrons or visitors, or to any other person whomsoever, for
any injury to person or damage to property on or about the Premises, resulting
from and/or caused in part or whole by, the negligence or misconduct of Tenant,
its employees, agents, invites, patrons or visitors, or caused by the buildings
and improvements located on the Premises becoming out of repair due to
activities of or arising at the instance of Tenant, its agents' or employees,
use, generation, storage or disposal of toxic or hazardous materials or
substances on or about the Premises due to activities of or arising at the
instance of Tenant, its agents or employees, or caused by leakage of gas, oil,
water or steam or by electricity emanating from the Premises, and Tenant hereby
covenants and agrees that it will at all times indemnify and hold safe and
harmless the Premises, Landlord and Landlord's agents and employees from any
loss, liability, claims, suits, costs, expenses, including without limitation,
reasonable attorney's fees and damages, both real and alleged, arising out of
any such damage or injury, except injury to persons or damage to property the
cause of which is the negligence or misconduct of Landlord or the failure of
Landlord to repair any part of the Premises which Landlord is obligated to
repair and maintain hereunder within a reasonable time after the receipt of
written notice from Tenant of needed repairs. Landlord hereby covenants and
agrees that it will at all times indemnify and hold safe and harmless Tenant and
Tenant's agents, employees, invitees and customers from any loss, liability,
claims, suits, costs, expenses, including without limitation, reasonable
attorney's fees and damages, both real and alleged, for any injury to person or
damage to property on or about the Premises resulting from and/or caused in part
or whole by, the negligence or misconduct of Landlord, its employees, agents,
invites, patrons or visitors, or caused by the buildings and improvements
located on the Premises becoming out of repair due to activities of or arising
at the instance of Landlord, its agents or employees, use, generation, storage
or disposal of toxic or hazardous materials or substances on or about the
Premises due to activities of or arising at the instance of Landlord, its agents
or employees, except injury to persons or damage to property the cause of which
is the negligence or misconduct of Tenant or the failure of Tenant to repair any
part of the Building which Tenant is obligated to repair and maintain hereunder
within a reasonable time after the receipt of written notice from Landlord of
needed repairs.

17.  CONDEMNATION.
     ------------

     (a) If eighty percent (80%) or more of the gross square footage of the
building in which the Premises are located should be taken for public or quasi-
public use under any governmental law, ordinance or regulation by right of
eminent domain, or by private purchase in lieu thereof, Landlord shall have the
right to terminate this Lease and the rent shall be abated effective on the date
of Landlord's election to so terminate. Additionally, if the whole or any part
of the Premises should be taken for any public or quasi-public use under any
governmental law, ordinance or regulation, or by right of eminent domain, or by
private purchase in lieu thereof and the taking would prevent or materially
interfere with the use of the Premises for the purpose for which they are being
used, this Lease shall terminate, whereupon all rights and obligations
hereunder shall cease and terminate, effective on the date of the physical
taking of the Premises.

     (b) If part of the Premises shall be taken for any public or quasi-public
use, under any governmental law, ordinance or regulation, or by right of eminent
domain, or by private purchase in lieu thereof, and this Lease is not terminated
as provided in subparagraph 17.a, this Lease shall not terminate but the rent
payable hereunder during the unexpired portion of this Lease shall be reduced to
such extent as may be fair and reasonable under all of the circumstances.

                                       10
<PAGE>

     (c) In the event of any such taking or private purchase in lieu thereof,
Landlord and Tenant shall each be entitled to receive and retain such separate
awards and/or portion of lump sum awards as may be allocated to their respective
interests in any condemnation proceedings.

18.  HOLDING OVER. Tenant shall, at the termination of this Lease by lapse of
     ------------
time or otherwise, deliver immediate possession of the Premises to Landlord. If
Landlord agrees in writing that Tenant may hold over after the expiration or
termination of this Lease, unless the parties hereto otherwise agree in writing
on the terms of such holding over, the hold over tenancy shall be subject to
termination by Landlord at any time upon not less than thirty (30) days advance
written notice, or by Tenant at any time upon not less than thirty (30) days
advance written notice, and all of the other terms and provisions of this Lease
shall be applicable during that period, except that Tenant shall pay Landlord,
from time to time, upon demand, as rental for the period of any such holding
over, an amount equal to one and one-fourth (1-1/4) of the rent in effect on the
termination date, computed on a daily basis for each day of the hold over
period. No holding over by Tenant, whether with or without consent of Landlord,
shall operate to extend this Lease except as otherwise expressly provided. The
preceding provisions of this Paragraph 18 shall not be construed as Landlord's
consent for Tenant to hold over.

19.  QUIET ENJOYMENT. Landlord represents and warrants that it has full right
     ---------------
and authority to enter into this Lease and that Tenant, upon paying the rental
herein set forth and performing its other covenants and agreements herein set
forth and performing its other covenants and agreements herein set forth, shall
peaceably and quietly have, hold and enjoy the Premises for the term hereof,
subject to the terms and provisions of this Lease.

20.  EVENTS OF DEFAULT. The following events shall each be deemed to be an event
     -----------------
of default by Tenant under the Lease:

     (a) Tenant shall fail to pay any installment of the rent herein required
within five (5) days after written notice thereof from Landlord to Tenant,
provided, however, that Landlord shall not be required to give such notice more
than twice in any calendar year.

     (b) Tenant shall become insolvent, or shall make a transfer to defraud
creditors, or shall make an assignment for the benefit of creditors.

     (c) Tenant shall file a petition under any section or chapter of the
National Bankruptcy Act, as amended, or under any similar law or statute of the
United States or any State thereof, or Tenant shall be adjudged bankrupt or
insolvent in proceedings filed against Tenant thereunder, and such petition or
proceeding is not vacated or stayed within ninety (90) days after it is filed.

     (d) A receiver or trustee shall be appointed for all or substantially all
of the assets of Tenant and such appointment is not vacated or stayed within
ninety (90) days after it is made.

     (e) Tenant shall desert, abandon or vacate the Premises and cease paying
rent hereunder.

     (f) Tenant shall fail to comply with any term, provision or covenant of
this Lease (other than as set forth in clauses (a) through (e) in this Paragraph
20), and shall not cure such failure within thirty (30) days after written
notice thereof to Tenant, unless such failure takes longer than thirty (30) days
to cure and Tenant commences to cure within said thirty (30)-day period and
diligently pursues the cure to completion, but in no event shall the thirty
(30)-day cure period be extended by more than sixty (60) additional days.

21.  REMEDIES. Upon the occurrence of any events of default described in
     --------
Paragraph 20 hereof, Landlord shall have the option to pursue any one or more of
the following remedies without notice or demand whatsoever, but subject to the
provisions of the Addendum attached to this Lease:

     (a) Terminate this Lease in which event Tenant shall immediately surrender
the Premises to Landlord, and if Tenant fails so to do, Landlord may, without
prejudice to any other remedy which it may

                                       11
<PAGE>

have for possession or arrearage in rent, avail itself of dispossessory
proceedings against Tenant, and Tenant agrees to pay to Landlord on demand the
amount of all loss and damages which Landlord may suffer by reason of such
termination, whether through inability to relet the Premises on satisfactory
terms or otherwise.

     (b) Enter upon and take possession of the Premises and expel or remove
Tenant and any other person who may be occupying the Premises or any part
thereof pursuant to any dispossessory proceeding against Tenant, without being
liable for prosecution or any claim for damages thereof, and relet the Premises
and receive the rent therefor; and Tenant agrees to pay to the Landlord on
demand any deficiency that may arise by reason of such reletting. In the event
Landlord is successful in reletting the Premises at a rental in excess of that
agreed to be paid by Tenant pursuant to the terms of this Lease, Landlord and
Tenant each mutually agree that Tenant shall not be entitled, under any
circumstances, to such excess rental, and Tenant does hereby specifically waive
any claim to such excess rental.

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

     (d) Landlord shall have all other rights and remedies provided by law or in
equity. In the event Tenant fails to pay any installment of rent hereunder
within five (5) days after such installment is due, to help defray the
additional cost to Landlord for processing such late payments, Tenant shall pay
to Landlord a late charge in an amount equal to five percent (5%) of such
installment; and the failure to pay such amount within ten (10) days shall be an
event of default hereunder after the expiration of five (5) days written notice
thereof from Landlord to Tenant and such late charge having not been paid by
Tenant. This provision for such late charge shall be in addition to all of
Landlord's other rights and remedies hereunder or at law and shall not be
construed as liquidated damages or as limiting Landlord's remedies in any
manner.

     (e) Landlord shall mitigate its damages by making reasonable efforts to
relet the Premises on reasonable terms. If Landlord relets for a period of time
longer than the current Demised Term, then any expenses related to the new
lease, including, without limitation, leasing commissions, free rent and tenant
improvements, shall be allocated throughout the entire reletting term to not
unduly reduce the amount of consideration received by Landlord during the
remaining period of the Demised Term. Pursuit of any of the foregoing remedies
shall not preclude pursuit of any of the other remedies 'herein provided or any
other remedies provided by law, nor shall pursuit of any remedy herein provided
constitute a forfeiture or waiver of any rent due to Landlord hereunder or any
damages accruing to Landlord by reason of the violation of any of the terms,
provisions and covenants herein contained. No act or thing done by the Landlord
or its' agents during the Demised Term shall be deemed a termination of this
Lease or any acceptance of the surrender of the Premises, and no agreement to
terminate this Lease or accept a surrender of the Premises shall be valid unless
in writing signed by Landlord. No waiver by Landlord or Tenant of any violation
or breach of any of the terms, provisions and covenants herein contained shall
be deemed or construed to constitute a waiver of any other violation or breach
of any of the terms, provisions and covenants herein contained. Landlord's
acceptance of the payment of rental or other payments hereunder after the
occurrence of an event of default shall not be construed as a waiver of such
default, unless Landlord so notifies Tenant in writing. Forbearance by Landlord
to enforce one or more of the remedies herein provided upon an event of default
shall, not be deemed or construed to constitute a waiver of such default or of
Landlord's right to enforce any such remedies with respect to such default or
any subsequent default.

     (f) Tenant agrees to indemnify and hold Landlord harmless from any and all
losses, costs, expenses (including, without limitation, reasonable attorney's
fees), liabilities, causes of action, suits, claims and damages arising out of
or in connection with any violation or breach of, or failure of Tenant to

                                       12
<PAGE>

fully and completely observe, satisfy, perform and comply with the terms and
conditions of this Lease, provided, however, that Tenant shall only be
responsible for Landlord's attorney's fee in the event that a judgment has been
rendered or a judicial decision or ruling has been issued against Tenant.

     (g) Landlord agrees to indemnify and hold Tenant harmless from any and all
losses, costs, expenses (including, without limitation, reasonable attorney's
fees), liabilities, causes of action, suits, claims and damages arising out of
or in connection with any violation or breach of, or failure of Landlord to
fully and completely observe, satisfy, perform and comply with the terms and
conditions of this Lease, provided, however, that Landlord shall only be
responsible for Tenant's attorney's fee in the event that a judgment has been
rendered or a judicial decision or ruling has been issued against Landlord.

22.  MORTGAGES. Tenant, hereby agrees and accepts that this Lease is and shall
     ---------
be subject and subordinate to any mortgage(s) and/or deeds to secure debt
(collectively referred to as the "Mortgage") now or any time hereafter
constituting a lien or charge upon the Premises or the improvements situated
thereon; provided, however, that, so long as Tenant fulfills all of its
obligations under this Lease, Tenant's possession of the Premises and Tenant's
other rights under this Lease shall not be disturbed or impaired by the holder
of any such Mortgage or any person claiming through or under Landlord.;
Notwithstanding the foregoing, if the holder of any such Mortgage elects to have
Tenant's interest in this Lease superior to any such instrument, then by notice
to Tenant from such holder, this Lease shall be deemed superior to such lien,
whether this Lease was executed before or after said Mortgage. Any documents
required to be executed to confirm such subordination, nondisturbance and
attornment shall be executed and delivered by the appropriate party within five
(5) business days after request in order to confirm the foregoing provisions.

     (a) If, in connection with obtaining financing or refinancing for the
Premises, or a sale of the Premises, any lender or purchaser shall request
reasonable modifications in this Lease as a condition to such financing or
purchase, Tenant will not unreasonably withhold or delay or defer its consent
thereto, provided that such modifications do not increase the obligations of
Tenant hereunder or adversely affect Tenant's rights hereunder.

23.  MECHANIC'S LIENS. Tenant shall have no authority, express or implied, to
     ----------------
create or place any lien or encumbrance of any kind or nature whatever upon or
in any matter to bind, the interest of Landlord in the Premises or to charge
the rental payable hereunder for any claim in favor of any person dealing with
Tenant, including those who may furnish materials or perform labor for any
construction or repairs and each such claim shall affect and each such lien
shall attached to, if at all, only the leasehold interest granted to Tenant by
this instrument. Tenant covenants and agrees that it will pay or cause to be
paid or have fully bonded within thirty (30) days after its receipt of notice
that a lien has been filed all sums legally due and payable by it on account of
any labor performed or materials furnished in connection with any work performed
by or at the request of Tenant on the Premises on which any lien is or can be
validly and legally asserted against its leasehold interest in the Premises or
the improvements thereon and that it will save and hold Landlord harmless from
any and all loss, cost or expense based on or arising out of asserted claims or
liens against the leasehold estate or against the right, title and interest of
Landlord in the Premises or under the terms of this Lease,

24.  NOTICES. Any notices, demands, payments or other communications required or
     -------

Lease of Tenant. If any of the rents, or other charges or sums payable by Tenant
to Landlord shall be overdue and unpaid, or should Landlord make payments on

much thereof as may be necessary to compensate Landlord toward the payment of
the rents, charges or other sums due from Tenant, or towards any loss, damage or
expense sustained by Landlord resulting from such default on the part of Tenant;
and in such event, Tenant shall, upon demand, restore the security deposit to
the original sum deposited. In the event Tenant performs all of Tenant's
obligations under this Lease, the security deposit shall be returned in full to
Tenant within thirty (30) days after the date of the expiration or sooner
termination of the term of this Lease and the surrender of the Premises by
Tenant in compliance with the provisions of this Lease.

27.  LIMITATIONS AND LANDLORD'S LIABILITY. Any liability for damages or breach
     ------------------------------------
or nonperformance by Landlord, or arising out of the subject matter of this
Lease or the relationship created hereby, shall be limited to, and collectible
only out of, Landlord's interest in the Premises and in particular the proceeds
received by it for the sale of the building and no personal liability is assumed
by, or shall at any time be asserted against, Landlord or its affiliated
corporations, its and their partners, venturers, directors, shareholders,
officers, agents, servants and employees, or any of its or their successors or
assigns, all such liability, if any, being expressly waived and released by
Tenant. Landlord's review, supervision, commenting on or approval of any aspect
of work to be done by or for Tenant is solely for Landlord's protection, and
except as expressly provided, creates no warranties or duties to Tenant or to
third parties.

28.  PARKING. Parking shall be available to Tenant on an exclusive basis for
     -------
forty-six (46) parking places. Tenant agrees not to overburden the parking
facilities and agrees to cooperate with Landlord in the use of parking
facilities. "Parking" as used herein means the use of Tenant's employees, its
visitors, invitees, and customers for the parking of motor vehicles for such
periods of time as are reasonably necessary in connection with use of and/or
visits to the Premises. No vehicle may be repaired or serviced in the parking
area and any vehicle deemed abandoned by Landlord will be towed from the project
and all cost therein shall be borne by Tenant. All driveways, ingress and
egress, and all parking spaces are for the joint use of all tenants. Except as
otherwise provided in this Lease and the Addendum attached hereto, no area
outside of the Premises shall be used by Tenant for storage without Landlord's
prior written permission. There shall be no parking permitted on any of the
streets. Tenant shall pay to Landlord as Additional Rent simultaneously with the
payment of Base Rent a charge for each parking space (the "Parking Charge").
During the first Lease Year, the Parking Charge will be $35.00 per month per
parking space. Beginning with the second Lease Year, and on the first day of
each subsequent Lease Year, the Parking Charge shall be increased by three
percent (3%) over the Parking Charge for the previous Lease Year. As used
herein, the term "Lease Year" shall mean each twelve calendar month period
during the Demised Term; provided, however, that the first Lease Year shall also
include any partial month after the Commencement Date.

29.  RULES AND REGULATIONS. This Lease is subject to such reasonable rules and
     ---------------------
regulations as may hereafter be adopted and promulgated by Landlord, provided
such rules and regulations (a) are not inconsistent with other rights granted to
Tenant under this Lease (and, in the event of any inconsistency between the
rules and regulations and this Lease, the terms and provisions of this Lease
shall govern), (b) do not unreasonably interfere with Tenant's normal business
operations or Tenant's use and enjoyment of the Premises, (c) do not require
payment of additional monies, and (d) are provided to Tenant at least thirty
(30) days prior to the effective date thereof. Landlord agrees to use reasonable
efforts to uniformly enforce all rules and regulations that are applicable to
all tenants in the Building.

Premises, Tenant shall pay to Landlord any amount reasonably estimated by

heating and air conditioning systems and equipment therein, in good condition
and repair, reasonable wear and tear and loss by casualty excepted; however,
Tenant shall not be required to return the Premises in a condition any better
than the condition it was taken at the beginning of the Demised Term. Tenant
shall also, prior to vacating the Premises, pay to Landlord the amount, as
estimated by Landlord, of Tenant's obligation hereunder for real estate taxes
and insurance premiums for the year in which this Lease expires or terminates if
not previously paid as part bf the Operating Costs. All such amounts shall be
used and held by Landlord for payment of such obligations of Tenant hereunder,
with Tenant being liable for any additional costs therefor upon demand by
Landlord, or with any excess to be promptly returned to Tenant after all such
obligations have been determined and satisfied, as the case may be. Any security
deposit held by Landlord shall be credited against the amount payable by Tenant
under this subparagraph 30.h.

     (i) If any clause, sentence, paragraph or provision of this Lease is
illegal, invalid or unenforceable under present or future laws effective during
the term of this Lease, then and in that event, it is the intention of the
parties hereto that the remainder of this Lease shall not be affected thereby,
and it is also the intention of the parties to this Lease that in lieu of each
clause, sentence, paragraph or provision of this Lease that is illegal, invalid
or unenforceable, there be added as a part of this Lease contract a clause,
sentence, paragraph or provision as similar in terms to such illegal, invalid or
unenforceable cause or provision as may be possible and be legal, valid and
enforceable.

reasonable attorneys' fees and expenses Landlord incurs in enforcing any of the
obligations of Tenant under this Lease, or in any litigation or negotiation in
which Landlord shall, by virtue of this Lease or Landlord's ownership of the
Premises, become involved in, through or on account of this Lease. Provided
Tenant is the prevailing party, Landlord agrees to pay reasonable attorneys'
fees and expenses Tenant incurs in enforcing any of

<PAGE>

the obligations of Landlord under this Lease, or in any litigation or
negotiation in which Tenant shall, by virtue of this Lease, become involved in,
through or on account of this Lease.

     (k)   This Lease shall create the relationship of landlord and tenant
between Landlord and Tenant; no estate shall pass out of Landlord; Tenant has
only a usufruct, not subject to levy and sale.

     (l)   Neither this Lease, nor any memorandum, affidavit or other writing
with respect thereto, shall be recorded by Tenant or by anyone acting through,
under or on behalf of Tenant, and the recording thereof in violation of this
provision shall make this Lease voidable at Landlord's election.

     (m)   All references in this Lease to "the date hereof" or similar
references shall be deemed to refer to the last date, in point of time, on which
all parties hereto have executed this Lease.

     (n)   This Lease may be executed in counterparts, each of which shall be
deemed an original and all of which shall constitute one and the same Lease

into consideration the tenant improvements, and giving a credit for any vacant
period and leasing commissions). If Tenant desires to renew this Lease, Tenant
shall so notify Landlord at least thirty (30) days after receipt of Landlord's
notice. If Landlord and Tenant cannot agree on the market rent, they agree to
submit the matter to arbitration as provided in this Lease.
