Landlord in the Premises in accordance with the Work Schedule, such improvements
shall be deemed so be "substantially completed" when Landlord, in its reasonable
judgment and in consultation with its architects and/or contractors, certifies
to Tenant that (i) such improvements have been substantially completed and (ii)
any certificate of occupancy necessary for Tenant's occupancy of the Premises in
accordance with the provisions of this Lease has been duly issued.

                                   ARTICLE III

                                      RENT

      3.1 BASE RENTAL: Tenant covenants and agrees to pay to Landlord the Base
Rental stipulated in Section 1.1(g), as same may be adjusted in accordance with
Section 3.2 below. The Base Rental (as so adjusted from time to time) shall be
payable monthly in advance in equal installments (initially as set out in
Section 1.1 (g), but as hereafter adjusted in accordance with Section 3.2) on
the first (1st) day of every calendar month during the Lease Term, prorated as
appropriate for partial months. If the Lease Term commences on other than the
first day of any calendar month, the first installment of Base Rental shall be a
prorated amount based upon the actual number of days in such month and shall be
due and payable on the Commencement Date.

      3.2 * See Sepcial Stipulations #1.

      3.3 OPERATING EXPENSE INCREASE:

            (a) Tenant covenants and agrees to pay to Landlord, as Operating
Expense Increase for each Expense Increase Year during the Lease Term, a sum
computed by subtracting the Operating Expense Base from the Operating Expenses
shown on the Operating Statement for the Expense Increase Year in question, and
multiplying the result by Tenant's Share. Under no circumstances shall Tenant be
entitled to any refund of or credit against Operating Expenses for any Expense
Increase Year should Operating Expenses ever be less than the Operating Expense
Base. Within one hundred twenty (120) days after the expiration of each Expense
Increase Year, Landlord shall furnish Tenant with an Operating Statement. The
Operating Expense Increase shall, except as provided in paragraph (b) of this
Section 3.3, be due from Tenant thirty (30) days after the rendering of the
Operating Statement for such Expense Increase Year.

            (b) Landlord may render an Estimated Operating Statement for any
Expense Increase Year. If and when so rendered from time to time, Tenant shall
pay to Landlord in advance on the first day of each calendar month the monthly
Estimated Operating Expense Increase installments provided for in such Estimated
Operating Statement, such payments to continue until another Estimated Operating
Statement is rendered. Upon the rendering of an Operating Statement for any
Expense Increase Year for which Estimated Operating Expense Increase
installments were paid by Tenant, Tenant shall, within thirty (30) days
thereafter, pay to Landlord the sum of (x) the excess, if any, of the Operating
Expense Increase due for such Expense Increase Year over the monthly Estimated
Operating Expense Increase installments paid by Tenant in respect of such
Expense Increase Year and (y) the excess, if any, of the Estimated Operating
Expense Increase installments due for the current Expense Increase Year, as
shown on the current Estimated Operating Statement, over the Estimated Operating
Expense Increase installments then being paid by Tenant multiplied by the number
of months which shall have elapsed, in whole or in part, since the commencement
of the current Expense Increase Year. If Tenant's Estimated Operating Expense
Increase installments for the prior or current Expense Increase Year shall
exceed the Operating Expense Increase due for the prior Expense Increase Year or
the Estimated Operating Expense Increase due for the current Expense Increase
Year, respectively, such excess shall first be credited against any amounts
shown due on the Operating Statement and the Estimated Operating Statement and
the balance, if any, shall be credited against the next succeeding installment
or installments of Operating Expense Increase or Estimated Operating Expense
Increase becoming due hereunder; provided, however, that if the Lease Term shall
expire or this Lease shall terminate prior to full application of such credit,
any balance due Tenant shall be refunded to Tenant by Landlord if Tenant is not
in default under this Lease (and, if Tenant is in default hereunder, such
balance shall be held as additional security for Tenant's performance, may be
applied by Landlord toward the cure of any such default and shall not be
refunded until any such default is completely cured by Tenant).

            (c) Operating Expense Increase shall be prorated on a daily basis
for any Expense Increase Year not wholly failing within the Lease Term.

            (d) Tenant acknowledges that certain Operating Expenses will vary
depending on overall occupancy levels in the Building. If the average occupancy
level of the Building was less than ninety-five percent (95%) of the total
rentable square footage of the Building during the Base Year or any Expense
Increase Year, the actual Operating Expenses for the Base Year or Expense
Increase Year in question, as applicable, shall be adjusted to equal Landlord's
reasonable estimate of Operating Expenses had ninety-five percent (95%) of the
total rentable square footage of the Building been occupied. Landlord and Tenant
further acknowledge that the Building is part of the larger Tower Place Complex,
and that certain of the costs of management, operation, maintenance, repair and
security of the Tower Place Complex from time to time shall be allocated among
and shared by two or more of the improvements in the Tower Place Complex
(including the Building). It is also understood that certain costs incurred with
respect to various facilities surrounding the Building may, from time to time,
be allocated (if appropriate) entirely to the Building. The determination of all
such costs and their allocation shall be made by

                                                                ----------------

Landlord in accordance with sound accounting principles. Accordingly, the term
"Operating Expenses", as used in this Lease with respect to the Building, shall
from time to time include some of the costs, expenses, and taxes enumerated in
Exhibit "D" to this Lease which were incurred with respect to and allocated to
or shared by the Building in accordance with the foregoing. Notwithstanding the
foregoing or anything else contained in this Lease to the contrary, Tenant
understands and agrees that its rights to use other portions of the Tower Place
Complex of which the Building is a part (including the Common Areas) are those
available to the general public and that this Lease does not grant to it
additional rights of use. Specifically, but without limitation, nothing in this
Lease affords Tenant any rights of parking within the Tower Place Complex except
as may be expressly provided in Section 8.27 hereof.

      3.4 GENERAL PROVISIONS REGARDING RENT:

            (a) The provisions of this Article concerning the payment of
Operating Expense Increase shall survive the expiration or earlier termination
of the Lease Term as to any and all sums due Landlord up to the date thereof,
including Operating Expense Increase due for the last Expense Increase Year, or
portion thereof, falling within the Lease Term, which sum shall be paid promptly
by Tenant in accordance with the terms of this Article III. Within one hundred
twenty (120) days following the expiration or earlier termination of the Lease
Term, Landlord shall render a final Operating Statement, certified by Landlord,
and Landlord and Tenant shall adjust the Operating Expense Increase payment or
credit due Landlord or Tenant, as the case may be, for the last Expense Increase
Year of the Lease Term, all in accordance with the foregoing provisions of
Section 3.3.

            (b) It is understood and agreed that Tenant's payments of Operating
Expense Increase shall not be deemed payments of rental as that term is
construed in relation to governmental wage and price control or analogous
governmental actions affecting the amount of rental which Landlord may charge
Tenant. Notwithstanding the foregoing, in the event that such governmental
actions or controls prevent the application of all or any part of the provisions
of this Article III regarding the payment of Operating Expense Increase, Tenant
hereby agrees to pay as monthly rent hereunder the monthly Base Rental plus
one-twelfth (1/12) of the Operating Expense Increase which was due for the
Expense Increase Year preceding the year of the institution of such actions or
controls, but in no case to exceed the maximum rent permitted by such actions or
controls.

            (c) Tenant covenants and agrees to be liable for and to pay in a
timely manner all taxes and assessments levied or assessed against personal
property, furniture and fixtures placed by Tenant in the Premises. Further, and
in addition to the Base Rental and Operating Expense Increase, Tenant shall
reimburse Landlord, within the thirty (30) days after written demand, for any
and all taxes payable by Landlord (other than net income taxes), whether or not
now customary or within the contemplation of the parties hereto, (i) upon,
measured by or reasonably attributable to the cost or value of Tenant's
equipment, furniture, fixtures, or personal property located in the Premises, or
any leasehold improvements made in or to the Premises by or for Tenant,
regardless of whether such improvements were constructed by Landlord or Tenant
and regardless of whether title to such improvements shall be in the name of
Landlord or Tenant; (ii) upon, measured by or reasonably attributable to the
Total Rent payable hereunder, or any component thereof, levied by any
governmental body with respect to the receipt of such Total Rent; (iii) upon or
with respect to the possession, leasing, operation, management, maintenance,
alteration, repair, use or occupancy by Tenant of the Premises or any portion
thereof; and, (iv) upon this transaction or any document to which Tenant is a
party creating or transferring rights, an interest or an estate in the Premises.
In the event that it shall not be lawful for Tenant so to reimburse Landlord,
the monthly Base Rental payable to Landlord under this Lease shall, to the
maximum extent permitted by law, be revised to net Landlord the same net Base
Rental after imposition of any such tax upon Landlord as would have been payable
to Landlord prior to the imposition of any such tax. Tenant shall also be solely
liable for any taxes, including rental, sales and use taxes, assessed directly
against Tenant by any governmental authority.

            (d) It is understood and agreed that Base Rental and Operating
Expense Increase shall be due and payable as provided herein, without set off or
deduction whatsoever. Base Rental, Operating Expense Increase and each and every
other charge, fee, cost or expense which Tenant is obligated or liable to pay
to, refund to or reimburse Landlord shall, for the purposes of the default
provisions of this Lease, be deemed additional rental due from Tenant, and
Tenant's failure to so pay, refund or reimburse when due shall entitle Landlord
to all the remedies provided for herein and at law or in equity on account of
failure to pay rent.

            (e) Base Rental, Operating Expense Increase and other sums due
hereunder shall be paid in legal tender at Manager's address set forth in
Section 8.1, or to such other address as may be specified by Landlord by notice
given from time to time as provided in such Section 8.1. No payment by Tenant or
receipt by Landlord of a lesser amount than the monthly installment of Base
Rental or any other component of Total Rent due under this Lease shall be deemed
to be other than on account of the earliest Base Rental or other such component
of Total Rent due hereunder, nor shall any endorsement or statement on any check
or any letter accompanying any check or payment of Total Rent (or any portion
thereof) 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 Total Rent or to pursue any other remedy provided in this Lease or under
applicable law.

            (f) Delay by Landlord in providing Tenant with any statements
regarding Operating Expense Increase shall not relieve Tenant from the
obligation to pay Operating Expense Increase upon the rendering of such
statements.

      3.5 INITIAL INSTALLMENT: Simultaneously with the execution of this Lease,
Tenant has paid to Landlord, and Landlord hereby acknowledges the receipt of,
the Initial Installment. Such sum shall be applied by Landlord to the first
monthly installment(s) of Base Rental as they become due hereunder. In the event
Tenant fails to take possession of the Premises in accordance with all the terms
hereof, such sum shall be retained by Landlord for application in reduction, but
not in satisfaction, of damages suffered by Landlord as a result of such breach
by Tenant.

      3.7 LANDLORD'S SECURITY INTEREST: In addition to any landlord's lien
arising at law or by statute, Landlord shall have, at all times, and Tenant
hereby grants to Landlord a valid security interest, to secure payment of Total
Rent and other sums of money becoming due hereunder from Tenant, and to secure
performance by Tenant of any covenant, agreement or condition contained herein,
in and upon all goods, wares, equipment, fixtures, furniture, improvements and
other personal property of Tenant presently or which may hereinafter be situated
in the Premises, and all proceeds therefrom, and such property shall not be
removed therefrom without the consent of Landlord until all arranges in Total
Rent as well as any and all other sums of money then due to Landlord hereunder
shall first have been paid and discharged and all of the covenants, agreements,
and conditions hereof have been fully complied with and performed by Tenant.
This provision shall be considered a security agreement and, in consideration of
this Lease, upon the occurrence of an Event of Default by Tenant, Landlord may,
in addition to any other remedies provided herein, exercise all remedies granted
a "Secured Party" under the Uniform Commercial Code in force in the State of
Georgia. Without limitation, Landlord may enter upon the Premises and take
possession of any and all goods, wares, equipment, fixtures, furniture,
improvements, and other personal property of Tenant situated on or in the
Premises, without liability for trespass or conversion, and sell the same at
public or private sale, with or without having such property at the sale, after
giving Tenant reasonable notice of the time and place of any public sale or of
the time after which any private sale is to be made, for cash or on credit, or
for such price and terms as Landlord deems best, at which sale the Landlord or
its assigns may purchase unless otherwise prohibited by law. Unless otherwise
provided by law, and without intending to exclude any other manner of giving
Tenant reasonable notice, the requirement of reasonable notice shall be met if
such notice is given in the manner prescribed in Section 8.1 of this Lease at
least five (5) days before the time of sale. Landlord may also, at its option,
foreclose the lien created hereby in the manner and form provided for the
foreclosure of security instruments or in any other manner permitted by law. The
proceeds from any such disposition, less any and all expenses connected with the
taking of possession, holding and selling of the property (including reasonable
attorneys' fees and other expenses), shall be applied as a credit against the
indebtedness secured by the security interest granted in this Section 3.7. Any
surplus shall be paid to Tenant or as otherwise required by law, and Tenant
shall pay any deficiencies forthwith. Upon request by Landlord, Tenant agrees to
execute and deliver to Landlord a financing statement or statements (and
continuation statements as necessary) in form sufficient to perfect the security
interest of Landlord in the aforementioned property and proceeds thereof under
the provisions of the Uniform Commercial Code in force in the State of Georgia.
Any statutory or common law lien for rent is not hereby waived, the security
interest herein granted being in addition and supplementary thereto.

                       RIGHTS AND DUTIES DURING LEASE TERM

      4.1 PREPARATION OF THE PREMISES:

            (a) Tenant acknowledges that it has inspected the Premises, that
Landlord has made no representations or warranties whatsoever respecting the
condition thereof or otherwise and that, except as may be expressly provided to
the contrary in the Work Schedule, Landlord has no obligation or duty to make
any alterations, improvements or repairs whatsoever in and to the Premises to
make same ready for Tenant's use and occupancy and Tenant takes and accepts the
Premises in their present "as is" condition. By occupying the Premises, Tenant
shall be deemed conclusively to have accepted the Premises as complying fully
with Landlord's covenants and obligations.

            (b) Initial improvements to the Premises, if any, shall be governed
by the Work Schedule.

            (c) If the installation of improvements in the Premises causes an
increase in the ad valorem taxes levied or assessed on the Building, Tenant
shall reimburse any such increase to Landlord within thirty (30) days following
written demand by Landlord as contemplated by Section 3.4(c).

            (d) Within thirty (30) days after the Commencement Date, Tenant will

specifically required to be paid for directly by Tenant, shall be included

request by Tenant delivered to the Building's Manager during normal business
hours at least twenty-four (24) hours prior to the time when such service is
desired. Any additional service so provided shall be at Tenants expense at such
hourly rates as may be determined from time to time by Landlord, which charge
Tenant shall promptly pay upon being

billed therefore. Landlord reserves the right to prohibit the use of heat
generating machines and equipment unless and until Tenant makes arrangements,
acceptable to Landlord, to install and maintain supplementary air-conditioning
equipment in the Premises at Tenant's cost and expense, and the costs of
operation of such shall be paid by Tenant on the Base Rental payment dates at
such rates as are established by Landlord; provided, however, that the
maintenance of such supplementary air-conditioning equipment shall be solely
Tenant's, and not Landlord's, duty and responsibility;

            (c) 110 volt electric current for lighting and for usual and normal
electric power for office space, all from existing electric circuits designated
by Landlord for Tenant's use. Landlord reserves the right to meter the Premises
or any portion thereof separately, and if the Premises (or any portions thereof)
are so separately metered, Tenant shall pay for all electricity furnished to the
Premises which is so separately metered. Tenant shall not, without Landlord's
prior written consent, use any equipment, including, without limitation,
electronic data processing machines, punch card machines, duplicating machines,
main frame computers, photocopiers, printers or any other machines which use
electric current in excess of 110 volts, which will increase the amount of
electricity ordinarily furnished for the use of the Premises as general office
space or which require clean circuits or other special distribution circuits. If
Tenant desires additional 110 volt electrical power beyond that supplied by
Landlord as provided above, electric current in excess of 110 volts, or other
special power requirements or circuits, then Tenant may request Landlord to
provide such supplemental power to the Premises, which request Landlord may
grant or withhold in its reasonable discretion. If Landlord furnishes such power
or circuits, Tenant shall pay Landlord, on demand, the cost of the design,
installation, and maintenance of the facilities required to provide such
additional or special electric power or circuits and the cost of all electric
current so provided at a rate not to exceed the actual cost to Landlord for such
current. Landlord may require separate electrical metering of such supplemental
electrical power or circuits to the Premises, and Tenant shall pay, on demand,
the cost of the design, installation, and maintenance of such metering
facilities. In no event shall Tenant have access to any electrical closets in
the Building, it being agreed that any electrical engineering design or contract
work shall be performed by Landlord or an electrical engineer and/or electrical
contractor designated by Landlord at Tenant's expense; See Special Stipulation
#2

            (d) Common use restrooms and toilets with hot and cold running
water; and

            (e) Drinking water available on each floor of the Building.

      4.3 LIABILITY OF LANDLORD: Landlord shall not be liable to Tenant in any
manner whatsoever for failure to furnish or delay in furnishing any service or
services provided for in this Lease and no such failure or delay shall
constitute actual or constructive eviction of Tenant or operate to relieve
Tenant from the prompt and punctual performance of each and all the covenants to
be performed herein by Tenant. Except in the case of Landlord's negligence,
Landlord shall also not be liable to Tenant for damage to person or property
caused by defects in, or repairs to, the cooling, heating, electric, water,
elevator or other apparatus or systems or by water discharged from sprinkler
systems, if any, in the Building; likewise, Landlord shall not be liable to
Tenant for the theft, mysterious disappearance, or loss of any property of
Tenant whether from the Premises or any part of the Building or Tower Place
Complex. Landlord agrees to make reasonable efforts to protect Tenant from
interference or disturbance by third persons, including other tenants; however
except in the case of Landlord's negligence, Landlord shall not be liable, and
Tenant shall not be relieved from its obligations hereunder, for any such
interference or disturbance, whether caused by another tenant or tenants of
Landlord, or by other persons.

      4.4 REPAIRS BY LANDLORD: Landlord shall have no duty to make any repairs
or improvements to the Premises except structural repairs and repairs to the
Building's base electrical, mechanical and plumbing systems necessary for safety
and tenantability, the necessity for which (i) Landlord is notified in writing
by Tenant, and (ii) is not brought about by any act or neglect of Tenant, its
agents, employees or visitors. Landlord shall not be liable for any failure to
make repairs or to perform any maintenance required hereunder unless such
failure shall persist for an unreasonable time after written notice of the need
of such repairs or maintenance is given to Landlord by Tenant in accordance with
Section 8.1 of this Lease. Tenant waives the right to make repairs at Landlord's
expense under any law, statute or ordinance now, or hereafter in effect.

      4.5 RIGHTS OF LANDLORD TO ENTER PREMISES: Tenant shall not change the
locks on any entrance to the Premises. Upon Tenant's written request to
Landlord, Landlord agrees to make a reasonable change of locks on behalf of
Tenant and at Tenant's sole cost and expense. Landlord and its agents, employees
and contractors may enter the Premises at such times as Landlord deems
reasonably necessary or desirable to inspect and examine same, to make such
repairs, additions, alterations, and improvements as Landlord desires to make to
the Building, including, without limitation, the erection, use and maintenance
of pipes and conduits, to supply janitorial service and any other service to be
provided by Landlord to Tenant hereunder, and to exhibit the Premises to
prospective purchasers or tenants. In the event of emergency, or if otherwise
necessary to prevent injury to persons or damage to property, such entry to the
Premises may be made by force without any liability whatsoever on the part of
Landlord for any resulting damage. Landlord may also take any and all needed
materials into and through the Premises that may be required to make such
repairs, additions, alterations, and improvements, all without being liable to
Tenant in any manner whatsoever. During such time as such work is being carried
on, provided such work is carried out in a manner so as not unreasonably to
interfere with the use and occupancy of the Premises by Tenant, Total Rent (nor
any portion thereof) shall in no way abate, and, regardless of Landlord's fault,
Tenant waives any claim and cause of action against Landlord for damages by
reason of loss or interruption to Tenant's business and profits therefrom
because of the prosecution of any such work.

      4.6 AGREEMENTS OF TENANT: Tenant agrees that it shall:

            (a) at its own expense and except for the obligations of Landlord
expressly stated in Section 4.4 of this Lease, keep the Premises in good repair
and tenantable condition and indemnify Landlord against any loss, damage, or
expense arising by any failure of Tenant so to do or due to any act or neglect
of Tenant, its employees, agents or visitors;

            (b) make no alterations or additions of any kind in or to the
Premises or the Building without first obtaining Landlord's written consent
which shall not be unreasonably withheld; all such work, including additions,
fixtures and leasehold improvements (but not including moveable office furniture
and equipment and other personal property of Tenant), made or placed in or upon
the Premises or the Building either by Tenant or Landlord shall be and become
Landlord's property at the end of the Lease Term, all without compensation or

            (c) not use the Premises for any illegal purpose or violate any
statute, regulation, rule or order of any governmental body, nor create or allow
to exist any nuisances or trespasses, nor do any act in or about the Premises or
bring anything onto or into the Premises which will in any way increase the rate
of insurance on the Premises or reduce the value of the Building or its
attractiveness to other tenants, nor will Tenant deface or injure the Premises
or commit or allow waste to be committed on any portion thereof or overload any
floor of the Premises;

            (d) at its sole expense comply, as to its use of the Premises, with
all statutes, regulations, rules, ordinances and orders of any governmental
body, department or agency thereof, and abide by and observe the Rules and
Regulations;

            (e) indemnify and hold Landlord harmless from and against any and
all loss, cost, damage, expense, or liability whatsoever, including, without
limitation, court costs and reasonable attorneys' fees, imposed on Landlord by
any person whomsoever, caused in whole or in part by an act or omission of
Tenant or its agents, employees, invitees, licensees, contractors, subtenants or
assignees (the provisions of this Subsection to survive expiration or
termination of this Lease with respect to any act or omission occurring prior to
such expiration or termination);

            (f) report immediately in writing to Landlord any defective
condition in or about the Premises known to Tenant, and a failure so to report
shall make Tenant liable to Landlord for any expense or damage to Landlord
resulting from such defective condition;

            (g) pay interest to Landlord on demand, at the rate of one and
one-half percent (1 1/2%) per month or the maximum rate permitted by law,
whichever is lower, on any installment of Total Rent not paid when due, accruing
from the due date until paid;

            (h) pay to Landlord on demand, in the event that Landlord elects to
accept a payment of any part of the Total Rent which is not received by Landlord
within seven (7) days of its due date, a late charge in an amount equal to the
greater of Fifty Dollars ($50.00) or five percent (5%) of the total outstanding
amount due (which late charge represents an agreed upon charge for Landlord's
administrative expenses in processing late payments, and is not a payment for
the use of money or a penalty); provided, however, nothing contained herein
shall be deemed to require Landlord to accept any payment of Total Rent received
by Landlord after the due date;

            (i) pay to Landlord a processing and handling fee of Fifty Dollars
($50.00) for any check of Tenant's which is returned to Landlord because of
insufficient funds, as liquidated damages to compensate Landlord for its
additional administrative costs and expenses in handling such items, it being
agreed that the exact amount thereof would be difficult or impossible to
ascertain;

            (j) cooperate with Landlord in complying with all regulations of the
United States Department of Energy and of any governmental agency having
jurisdiction of the Building and/or Tower Place Complex, relating to the
conservation of energy, including, without limitation, any regulations requiring
the production of information regarding the consumption of energy within the
Building and/or Tower Place Complex, and Tenant shall indemnify and hold
Landlord harmless from and against any loss, cost, damage, or liability arising
out of any violation of any such regulations by Tenant, its employees, agents,
contractors, invitees, licensees, subtenants and assignees; and

            (k) install telephone service to the Premises only from the
telephone circuits designated by Landlord in writing as those serving the
Premises; if Tenant requires additional telephone service capacity for the
Premises, such capacity must be provided by a telecommunications provider
approved by Landlord, at no cost to Landlord, and the design and installation of
such supplemental capacity shall be subject to the reasonable approval of
Landlord.

      4.7 SIGNS: Tenant shall obtain the written approval of Landlord prior to
placing and maintaining, or causing or permitting to be placed and maintained,
any sign, advertising matter or other thing of any kind, on the exterior of the
Premises, or any decorating, lettering or advertising matter on any exterior
door to the Premises. Tenant shall not affix or attach anything to windows in
the Premises or, without Landlord's prior written consent in each instance
(which may be given on such condition as Landlord may reasonably elect), place
signs or similar matter on the Premises which will be visible from outside the
Premises. All exterior and elevator lobby signs shall, unless Landlord otherwise
specifically consents in writing, conform to uniform Building sign
specifications promulgated by Landlord and Landlord shall provide and install
same at Tenant's cost and expense.

      4.8 BUILDING NAME: Tenant acknowledges that the Building is part of the
Tower Place Complex known generally as "Tower Place." Tenant covenants and
agrees to cause all directory listings, advertising and all other printed or
written material containing Tenant's address at the Premises accurately to refer
to "Tower Place" or any other name given the Building and/or Tower Place Complex
by Landlord in accordance herewith; however, Tenant shall not, without the prior
written consent of Landlord, use the name Tower Place or any other name given
the Building or Tower Place Complex, or any other deceptively similar name, or
any associated service mark or logo of the Building and/or Tower Place Complex
for any purpose other than Tenant's business address and Tenant, under no
circumstances, shall use the word "Courtyard" in any signage or advertisement.
Upon written notice to Tenant, Landlord reserves the right, from time to time
and at its sole option, to name or change the name of the Building and/or Tower
Place Complex and to change the street address of the Building.

      4.9 HAZARDOUS MATERIALS:

            (a) Tenant hereby covenants that, from and after the date hereof and
thereafter during the Lease Term, Tenant shall not cause or permit any
"Hazardous Substances" (as hereinafter defined) to be placed, held, located or
disposed of in or about the Premises or the Tower Place Complex or any part of
either and that neither the Premises nor the Tower Place Complex, nor any part
of either, shall ever be used by Tenant or persons claiming under Tenant as a
storage site (whether permanent or temporary) for any Hazardous Substances. For
purposes of this Section 4.9, "Hazardous Substances" shall mean and include
those elements or compounds which are contained in the list of hazardous
substances adopted by the United States Environmental Protection Agency (EPA) or
the list of toxic pollutants designated by Congress or the EPA or which are
defined as hazardous, toxic, pollutant, infectious or radioactive by any other
federal, state or local statute, law, ordinance, code, rule, regulation, order
or decree regulating, relating to or imposing liability (including, without
limitation, strict liability) or

standards of conduct concerning, any hazardous, toxic or dangerous waste,
substance or material, as now or at any time hereafter in effect (collectively
"Environmental Laws").

            (b) Tenant hereby agrees to comply with all Environmental Laws with
regard to its use and occupancy of the Premises and to indemnify Landlord and
hold Landlord harmless from and against any and all losses, liabilities,
including strict liability, damages, injuries, expenses, including reasonable
attorneys' fees, costs of any settlement or judgment and claims of any and every
kind whatsoever paid, incurred or suffered by, or asserted against, Landlord by
any person, entity or governmental agency for, with respect to, or as a direct
or indirect result of Tenant's failure so to comply or the presence in, or the
escape, leakage, spillage, discharge, emission, or release from, the Premises of
any Hazardous Substance (including, without limitation, any losses, liabilities,
including strict liability, damages, injuries, expenses, including reasonable
attorneys' fees, costs of any settlement or judgment or claims asserted or
arising under the Comprehensive Environmental Response, Compensation and
Liability Act, any so-called federal, State or local "Superfund" or "Superlien"
laws or any other Environmental Law); provided, however, that the foregoing
indemnity is limited to matters arising solely from Tenant's violation of the
covenant contained in Subsection 4.9(a) above.

            (c) In the event Landlord suspects, in its reasonable opinion, that
Tenant has violated any of the covenants contained in this Section 4.9, or that
the Premises, Retail Complex or Tower Place Complex are not in compliance with
the Environmental Laws for any reason as to which Tenant is responsible
hereunder, or that the Premises, Retail Complex or Tower Place Complex are not
free of Hazardous Substances for any reason as to which Tenant is responsible
hereunder, Tenant shall take such steps as Landlord requires by written notice
to Tenant in order to confirm or deny such occurrences, including, without
limitation, the preparation of environmental studies, audits, surveys or
reports. In the event that Tenant fails to take such action, Landlord may take
such action and shall have such access to the Premises as Landlord deems
necessary, and the costs and expenses of all such actions taken by Landlord,
including, without limitation, Landlord's attorneys' fees, shall be due and
payable by Tenant upon demand therefor from Landlord as additional rent
hereunder. If any lender or governmental agency shall ever require testing to
ascertain whether or not there has been any release of hazardous materials, then
the reasonable costs thereof shall be reimbursed by Tenant to Landlord upon
demand as additional charges if such requirement applies to the Premises. In
addition, Tenant shall execute affidavits, representations and the like from
time to time at Landlord's request concerning Tenant's best knowledge and belief
concerning the presence of hazardous substances or materials on the Premises.
Further, Landlord reserves the right at any time and from time to time to enter
the Premises following reasonable advance notice thereof to Tenant (except in
cases of emergency) in order to perform periodic environmental studies, audits,
surveys and reports and in order to determine whether Tenant is in compliance
with the terms of this Section 4.9.

            (d) The obligations and liabilities of Tenant under this Section 4.9
shall survive the expiration or earlier termination of this Lease or other
enforcement of Landlord's remedies under this Lease.

      4.10 INSURANCE:

            (a) Tenant agrees that it shall carry fire and extended coverage
insurance insuring Tenant's interest in its improvements and betterments to the
Premises and any and all furniture, equipment, supplies, and other property
owned, leased, held or possessed by it and contained therein, in an amount equal
to the full insurable values thereof (it being understood that no lack of
inadequacy of insurance by Tenant shall in any event make Landlord subject to
any claim by virtue of any theft of or loss or damage to any uninsured or
inadequacy insured property).

            (b) Tenant shall also procure and maintain throughout the Lease Term
business interruption insurance in an amount that will reimburse Tenant for
direct or indirect loss of earnings attributable to all perils insured against
under this Section or attributable to the prevention of access to the Premises
by civil authority, and sufficient to reimburse Tenant for Total Rent in the
event of a casualty to, or temporary taking of, the Building or the Premises.

            (c) Tenant shall also procure and maintain throughout the Lease Term
a policy or policies of insurance, insuring Tenant, Landlord, Manager and any
other persons designated by Landlord, against any and all liability for injury
to or death of a person or persons and for damage to property occasioned by or
arising out of any construction work being done on the Premises, or arising out
of the condition, use, or occupancy of the Premises, or in any way occasioned by
or arising out of the activities of Tenant, its agents, employees, or licensees
in the Premises, or other portions of the Building or Tower Place Complex, in
amounts not less than $1,000,000 with respect to injuries to or death of any one
person, $1,000,000 with respect to any one casualty or occurrence and $1,000,000
with respect to property damage, or such higher annual policy aggregate limits
as Landlord may reasonably require from time to time during the Lease Term.
Tenant shall also carry or procure any other form or forms of insurance or any
changes or endorsements to the insurance required herein as Landlord or any
Mortgagee (as hereinafter defined) or lessor of Landlord may reasonably require,
from time to time, in form or in amounts.

            (d) Landlord and Tenant shall each have included in all policies of
insurance respectively obtained by them with respect to the Building and/or the
Premises a waiver by the insurer of all right of subrogation against the other
in connection with any loss or damage thereby insured against. So long as both
Landlord's and Tenant's policies then in force include such mutual waiver of
subrogation, Landlord and Tenant, to the fullest extent permitted by law, each
waive all right of recovery against the other for and agree to release the other
from liability for, loss or damage to the extent such loss or damage is covered
by valid and collectible insurance in effect at the time of such loss or damage.
If such waiver of subrogation shall not be obtainable or shall be obtainable
only at a premium over that chargeable without such waiver, the party seeking
such waiver shall notify the other thereof in writing, and the latter shall have
ten (10) days in which either (i) to procure on behalf of the notifying party
insurance with such waiver from a company or companies reasonably satisfactory
to the notifying party or (ii) to agree to pay such additional premium (in
Tenant's case, in the proportion which the rentable area of the Premises bears
to the area covered by the insurance policy of Landlord in question).

            (e) All insurance policies procured and maintained by Tenant
pursuant to this Subsection 4.10 shall be carried with companies licensed to do
business in the State of Georgia reasonably satisfactory to Landlord and shall
be noncancelable except after thirty (30) days' written notice to Landlord and
any designees of Landlord. Such policies or duly executed certificates of
insurance with respect thereto shall be delivered to Landlord prior to the date
that Tenant takes possession of the Premises, and renewals thereof as required
shall be delivered to Landlord at least thirty (30) days prior to the expiration
of each respective policy term. If Tenant shall fail to procure or maintain any
insurance required of Tenant

<PAGE>

hereunder, Landlord may, at its sole option, but shall not be required to,
procure and maintain the same at the cost and expense of Tenant, and Tenant
agrees to reimburse Landlord for same as additional rent due hereunder within
fifteen (15) days after receiving notice of the amount thereof from Landlord.

      4.11 LIENS: No work performed by Tenant in the Premises, whether pursuant
to this Lease or otherwise, whether in the nature of erection, construction,
alteration, addition, improvement, remodeling or repair, shall be deemed to be
for the immediate use and benefit of Landlord, and no mechanic's, materialman's
or other lien shall be allowed against the estate of Landlord by reason of any
consent given by Landlord to Tenant to improve the Premises. Tenant shall pay
promptly all persons furnishing labor or materials with respect to any work
performed by Tenant or its contractor on or about the Premises and Tenant shall
discharge of record within twenty (20) days following the filing thereof, by
payment or bonding, any mechanic's lien filed against the Premises, the Building
or the Tower Place Complex for work or materials claimed to have been furnished
to Tenant.

                            ASSIGNMENT AND SUBLETTING

      5.1 ASSIGNMENT AND SUBLETTING:

            (a) Tenant shall not, without the prior written consent of Landlord,
which shall not be unreasonably withheld, assign, hypothecate, or otherwise
transfer this Lease or any interest hereunder, or sublet the Premises or any
part thereof, or permit the use of the Premises by any party other than Tenant.
Landlord's consent or refusal to consent to a proposed assignment or sublease
must be an action which is taken reasonably and in good faith. For the purposes
of the immediately preceding sentence, Landlord shall be deemed to be acting
reasonably and in good faith in determining whether to consent to a proposed
assignment or sublease when Landlord considers such factors as, without
limitation, the identity and business reputation of the proposed assignee or
subtenant, the relationship of the proposed assignee or subtenant to the tenant
mix in the Building and/or the Tower Place Complex, the type or nature of the
proposed assignee's or subtenant's business, the creditworthiness of the
proposed assignee or subtenant, and any agreement or leasing restrictions with
existing tenants or other third parties that prohibit or restrict Landlord from
leasing to the proposed assignee or subtenant. Tenant agrees to pay to Landlord
as additional rental, on demand, a Five Hundred Dollar ($500.00) administrative
processing fee in connection with any request by Tenant for consent to a
proposed assignment or subletting and, in addition, reasonable out-of-pocket
costs incurred by Landlord (including, without limitation, attorneys' fees) in
connection with any request by Tenant for Landlord to consent to any assignment
or subletting by Tenant. All monies so paid shall be non-refundable in any
event, regardless of whether Landlord consents to the proposed assignment or
subletting. Any assignment or sublease shall not nullify these provisions, and
all later assignments or subleases shall be made likewise only after the prior
written consent of Landlord is obtained in each instance.

            (b) No sublease or assignment by Tenant shall relieve Tenant of any
liability hereunder. Without limiting the foregoing, if, with the consent of
Landlord, this Lease is assigned or the Premises or any part thereof is sublet
or occupied by any party other than Tenant, Landlord may, after default by
Tenant, collect rent from the assignee, subtenant or occupant, and apply the net
amount collected to the Total Rent herein reserved, but no such assignment,
subletting, occupancy, or collection shall be deemed (i) a waiver of any of
Tenant's covenants contained in this Lease, (ii) the acceptance by Landlord of
the assignee, subtenant, or occupancy as Tenant hereunder, or (iii) the release
of Tenant from further performance by Tenant of its covenants under this Lease.

            (c) The occupancy of the Premises by any successor firm or entity of
the Tenant or by any firm or entity into which or with which the Tenant may
become merged or consolidated shall be deemed an assignment of this Lease
requiring the prior written consent of Landlord.

            (d) Notwithstanding the giving by Landlord of its consent to any
assignment or sublease with respect to the Premises, no such assignee or
sublessee may exercise any expansion option, right of first refusal option, or
renewal option under this Lease, nor shall any such party have the benefit of
any specific signage or other similar privileges or rights which may be provided
to Tenant under this Lease except in accordance with a separate written
agreement entered into directly between such assignee or sublessee and Landlord.
After a permitted assignment or subletting, the original Tenant shall have no
right to exercise on behalf of a permitted assignee or sublessee as to the space
assigned or sublet any expansion option, right of first refusal option or
renewal or extension option.

            (e) Should Landlord permit any assignment or subletting by Tenant
and should the monies received as a result of such assignment or subletting
(when compared to the monies still payable by Tenant to Landlord) be greater
than Landlord would have received hereunder had not Landlord permitted such
assignment or subletting, then fifty percent (50%) of the "Gross Profit", shall
be payable by Tenant to Landlord, it being the parties' intention that Landlord,
in consideration of Landlord's permitting such assignment or subletting, shall
receive fifty percent (50%) of any Gross Profit from any such assignment or
subletting. Further, should the assignment or subletting giving rise to the
Gross Profit be arranged by Landlord (or its Manager) on Tenant's behalf (it
being understood that neither Landlord nor its Manager shall have any obligation
to arrange for same), one hundred percent (100%) of the Gross Profit shall be
paid to Landlord.

                              DEFAULT AND REMEDIES

      6.1 EVENTS OF DEFAULT: The occurrence of any of the following shall
constitute "Events of Default" (each an "Event of Default"):

            (a) Any part, portion or component of the Total Rent, or any other
sums payable under this Lease, or otherwise, not received when due;

                                                                ----------------

<PAGE>

            (b) The Premises are deserted, vacated, or not used as regularly or
consistently as would normally be expected for similar premises put to the same
or similar purposes as set forth in Section 2.1, even though Tenant continues to
pay Total Rent;

            (c) Any petition is filed by or against Tenant under any section or
chapter of the Federal Bankruptcy Code, and, in the case of a petition filed
against Tenant, such petition is not dismissed within sixty (60) days after the
date of such filing;

            (d) Tenant becomes insolvent or transfers property in fraud of
creditors;

            (e) Tenant makes an assignment for the benefit of creditors;

            (f) A receiver is appointed for any of the Tenants assets; or

            (g) Tenant breaches or fails to comply with any term, provision,
condition or covenant of this Lease, other than the payment of Total Rent, or
any of the Rules and Regulations, excepting Tenant shall not be deemed in
default if it commences to cure said default in a timely manner and diligently
proceeds to cure said default expeditiously.

      6.2 REMEDIES:

            (a) Upon the occurrence of an event of default, Landlord shall have
the option to do and perform any one or more of the following, in addition to,
and not in limitation of, any other right or remedy available to Landlord at law
or in equity or elsewhere under this Lease if the events of default described in
Subsections 6.1(a) or (b) are not cured within five (5) days after written
notice by Landlord of such default, if the events described in Subsection 6.1(g)
are not cured within twenty (20) days after written notice of such default
(unless such default gives rise to immediate threat to person or property, in
which case such event of default shall immediately entitle Landlord to its
rights and remedies) or if any of the other events of default are not cured
immediately:

                  (i) terminate this Lease, in which event Tenant shall
immediately surrender the Premises to Landlord, but if Tenant shall fail to do
so, Landlord may, without further notice and without prejudice so any other
remedy Landlord may have for possession or arrearages in Total Rent, enter upon
the Premises and expel or remove Tenant and Tenant's effects, by force if
necessary, without being subject to prosecution or liable for any claim for
damages therefore; and Tenant agrees to indemnify Landlord for all loss and
damage which Landlord may suffer by reason of such termination, whether through
inability to relet the Premises, or through decrease in rent, or otherwise (such
agreement to survive any such termination of this Lease); and/or

                  (ii) terminate Tenant's right of possession of the Premises
without terminating this Lease, and enter the Premises as the agent of Tenant,
by force if necessary, without being subject to prosecution or liable for any
claim for damages therefore, and relet the Premises as the agent of Tenant
without advertisement and by private negotiations and or any term Landlord deems
proper, and receive the rent therefor, and Tenant shall pay Landlord upon demand
any deficiency that may arise by reason of such reletting, but Tenant shall not
be entitled to any surplus funds generated by such reletting; Tenant shall
reimburse Landlord for all costs of reletting the Premises, including, but not
limited to, advertising expenses, commissions, and the cost of improvements
reasonably required in order to relet the Premises; and/or

                  (iii) as agent of Tenant, do whatever Tenant is obligated to
do by the provisions of this Lease and enter the Premises, by force if
necessary, without being subject to prosecution or liable for any claims for
damages therefor, in order to accomplish this purpose; Tenant agrees to
reimburse Landlord immediately upon demand for any expenses which Landlord may
incur in thus effecting compliance with this Lease on behalf of Tenant, and
Tenant further agrees that Landlord shall not be liable for any damages
resulting to Tenant from such action, whether caused by the negligence of
Landlord or otherwise; and/or

                  (iv) collect as liquidated damages and not as a penalty, and
in addition so all Total Rent and other amounts previously due and unpaid under
the terms and conditions of the Lease, the accelerated present value of the
Total Rent, and all other sums provided herein to be paid by Tenant during the
remainder of the Lease Term (the "Rent Balance"), less the Net Rental Value of
the Premises, as hereinafter defined; the term "Net Rental Value" shall mean the
fair rental value of the Premises for the remainder of the Lease Term reduced to
present value, less the Landlord's costs, expenses and attorneys' fees in
connection with the preparation of the Premises for reletting and for the
reletting itself; provided, however, the parties agree that in no event shall
the Net Rental Value exceed the Rent Balance; the parties further agree that the
damages caused by the Tenant's default would be difficult or impossible
accurately to estimate and that this measure of damages is a reasonable
pre-estimate of the Landlord's probable loss resulting from Tenant's breach; the
acceptance of the liquidated damages set forth in this paragraph shall not
constitute a waiver of any failure of Tenant thereafter occurring to comply with
any term, provision, condition or covenant of this Lease.

            (b) If Landlord exercises any of the remedies set forth in Section
6.2(a) or under Georgia law, in addition to all other costs and expenses
Landlord shall be entitled to recover under this Lease, Landlord shall also be
entitled to recover:

                  (i) the cost of performing any other covenants which would
have otherwise been performed by Tenant;

                  (ii) the amount of any rental abatement or other rental
concession provided by Landlord to Tenant; provided, however, that in no event
shall Tenant's liability hereunder exceed the Total Rent due under this Lease;

                  (iii) all sums expended by Landlord, and not previously

                                   ARTICLE VII

                       DESTRUCTION OR DAMAGE: CONDEMNATION

      7.1 DESTRUCTION OF OR DAMAGE TO PREMISES: If because of fire, the
elements, or Act of God, the Premises or the Building is either destroyed or
damaged so as to render the Premises wholly unfit for occupancy, or if, in the
judgment of Landlord, the damage resulting cannot be repaired within sixty (60)
days from such damage, then at the option of Landlord to be exercised by giving
written notice to Tenant within sixty (60) days following the date of such
damage, this Lease shall terminate on the date of such election, and Tenant
shall immediately surrender the Premises to Landlord. In such event, and
regardless of whether Landlord elects to terminate this Lease, Tenant shall
continue to owe and pay Total Rent up to but not beyond the time of such
surrender, but Total Rent shall abate in proportion to the number of square feet
of rentable area of the Premises rendered unusable by such damage. Under no
circumstances shall Landlord be liable to Tenant for inconvenience, annoyance,
loss of profits, expenses, or any other type of injury or damage resulting from
the repair of any such damage, or from any repair, modification, arranging, or
rearranging of any portion of the Premises or any part or all of the Building or
for termination of this Lease as provided above. Tenant assumes the risks of any
and all damage to its personal property in or on the Premises and from any
casualty whatsoever.

      7.2 EMINENT DOMAIN: If all of the Premises or the Building is taken, or if
such a part of either is taken so as to render the remainder thereof unsuitable
for Landlord's or Tenant's purposes, for any public or quasi-public use by
eminent domain or by private purchase in lieu thereof, this Lease shall
terminate at the option of either Landlord or Tenant on the date that the
condemning authority actually takes possession of the part condemned. If this
Lease is not so terminated, or upon a taking not within the scope of the
foregoing, Total Rent shall abate for the period of such taking in proportion to
the area of the Premises taken. In no event shall Tenant have any right or claim
to any part of any award made to or received by Landlord for such taking, or
against Landlord or the condemning authority for the value of any unexpired term
of this Lease, and Tenant hereby assigns any such claim to Landlord. Nothing
herein contained, however, shall preclude Tenant from claiming, proving and
receiving from the condemning authority a separate award for the value of any of
Tenant's personal property taken which Tenant could have rightfully removed from
the Premises hereunder and for relocation and moving expenses, so long as the
Landlord's award is not thereby reduced.

      7.3 DETERMINATION OF TIME REQUIRED TO REBUILD: Within ten (10) business
days following any casualty described in Section 7.1, or any taking described in
Section 7.2, Landlord shall give Tenant a notice stating (a) Landlord's estimate
of the portion of the Premises rendered untenable as a result of such casualty
or taking and (b) Landlord's estimate of the time required for restoration. If
Landlord and Tenant do not agree within ten (10) days after the casualty or
taking as to the length of time which would be required for restoration, the
issue shall be submitted, promptly, by both parties, or either party, to the
president or principal officer of the Atlanta, Georgia, Chapter of the American
Institute of Architects (or successor thereto) whose determination shall be
binding upon the parties. Landlord and Tenant shall share equally in the cost of
obtaining the opinion of said person.

            7.4 PARTIAL DESTRUCTION OR TAKING: If the Premises are damaged as a
result of a casualty described in Section 7.1 or a taking described in Section
7.2 but this Lease is not terminated as a result of such casualty or taking, all
rental shall abate in proportion to the amount of the Premises which shall have
been rendered unusable; provided, however, that Tenant's obligation to pay Total
Rent shall not cease or abate if the damage to the Premises or the Building was
caused through the negligence or willful misconduct of Tenant, its agents,
employees, contractors, invitees, licensees, subtenants, or assignees. Further,
in such a case, Landlord will promptly, at its sole cost and expense, restore,
replace or rebuild the same as nearly as possible to the structural and
architectural condition existing immediately prior to such casualty or taking
and as expeditiously as practicable but within a period beginning on the
earliest date upon which the time required for restoration has been determined
and any options of Landlord or Tenant to terminate this Lease, if any, have
expired, and having a length not exceeding one hundred twenty-five percent
(125%) of the length of time required to rebuild as determined pursuant to
Section 7.3 as the same may be extended pursuant to Section 8.23, whereupon full
rental shall recommence. If the damage or seizure affects more than twenty-five
percent (25%) of the area of the Premises, or such a fraction that would leave
the remainder of the Premises untenable and Landlord fails to complete such
restoration, replacement or rebuilding within such period, Tenant shall be
entitled at any time up to the earlier often (10) days following the expiration
of the time permitted for restoration or the actual date of completion of
restoration, replacement or rebuilding, by notice to Landlord, to terminate this
Lease as of a date not more than sixty (60) days following the date of such
notice. Notwithstanding anything herein contained to the contrary, Landlord
shall have no obligation to repair any improvements to the Premises constructed
by Tenant or Tenant's agents or contractors or, if constructed or installed by
Landlord, any improvements required to be insured by Tenant in accordance with
the provisions of this Lease (unless insurance proceeds for repair are made
available to Landlord) and Tenant shall, upon substantial completion by Landlord
of its repairs required hereunder, promptly and diligently and at its sole cost
and expense, repair and restore any improvements to the Premises made by Tenant,
as well as Tenant's contents, to the condition thereof prior to such destruction
or damage.

notice must be given or taken shall run from the date of receipt as indicated on
the return postal receipt. Rejection or other refusal to accept or the inability
to deliver because of changed address of which no notice was given shall be
deemed receipt of the notice, demand or request sent. Any party may change its
address for notices to any other location within the continental United States
by notifying the other parties of the new address in the manner provided herein
for the giving of notices, with such change to become effective ten (10) days
after notice of the change of address is given. For the purposes hereof, notices
to Tenant shall be sent to the addresses set out in Section 1.1(n). Notices to
Landlord and Manager shall be sent to the following addresses:

                     (i)    To Landlord:

                            Tower Place, L.P.
                            c/o Regent Partners, Inc.
                            3348 Peachtree Road, NE
                            Suite 1000
                            Atlanta, Georgia 30326
                            Attn: Debra Cobbs

                     (With a copy of any notice sent to Landlord sent also to
Manager at Manager's address set forth as provided herein); and

                     (ii)   To Manager:

                            Regent Partners, Inc.
                            Tower Place
                            3348 Peachtree Road, NE
                            Suite 1000
                            Atlanta, Georgia 30326
                            Attn: Property Manager

            (b) Tenant hereby designates and appoints as its agent to receive
notice of all dispossessory or distraint proceedings the person in charge of or
occupying the Premises at the time such notice is given, or, if there is no such
person, then such service of notice may be made by attaching it on the main
entrance of the Premises.

            (c) In the event that Landlord gives notice to Tenant of the name
and address of any holder of a Landlord's Mortgage (such holder being herein
referred to as a "Mortgagee"), Tenant agrees to send to any such Mortgagee, by
certified mail, a copy of any notice of default given by Tenant to Landlord.
Tenant further agrees that if such default is not cured by Landlord, the
Mortgagee shall be allowed thirty (30) days in which to cure the default or, if
the default cannot be cured within the thirty (30)-day period, to begin
diligently pursuing such cure. Nothing herein contained shall in any way
obligate the Mortgagee to cure or pursue the cure of any such default.

      8.2 MANAGER: Landlord shall have the right to delegate any and all of its
obligations under this Lease to an entity engaged in the operation and
management of office buildings in the metropolitan area of Atlanta, Georgia (any
such entity herein referred to as "Manager"). Such delegation shall not,
however, relieve Landlord of any such obligations. The initial Manager is as
stated in Section 1.1(o) and such Manager's address is set out in Section
8.1(a) above. Landlord may designate a replacement Manager at any time and from
time to time by notice to Tenant.

      8.3 SURRENDER OF PREMISES: Upon the expiration or other termination of the
Lease Term, as the same may have been extended, Tenant shall promptly quit and
surrender to Landlord the Premises (and the keys thereto), together with all
improvements belonging to Landlord, free of debris, broom clean, ordinary wear
and tear excepted, and Tenant shall remove all of its personal property required
or permitted to be removed hereunder; provided, however, that Tenant shall not
be permitted to remove any movable furniture, personal property, or equipment
from the Premises at any time, including at the end of the Term or any renewal
thereof or other sooner termination of this Lease, if Tenant is then in material
default under this Lease. All such property not promptly removed by Tenant shall
be deemed abandoned by Tenant, and title to the same shall pass to Landlord
under this Lease as by a bill of sale.

      8.4 HOLDING OVER: Should Tenant remain in possession of the Premises after
the expiration or other termination of the Lease Term, Tenant shall be a tenant
at sufferance (absent a written agreement to the contrary signed by Landlord) at
a rental rate equal to one hundred fifty percent (150%) of the Total Rent then
applicable hereunder, and otherwise on the same terms and conditions as herein
provided as applicable to a tenancy at sufferance. In addition, Tenant shall
indemnify and hold harmless Landlord from all loss or damage which may result
from Tenant's holding over. Without limiting the foregoing, Tenant shall
indemnify Landlord against all claims made by any other Tenant or prospective
Tenant against Landlord resulting from such delay by Landlord in delivering
possession of the Premises to such tenant or prospective Tenant. Nothing herein
shall be construed as constituting Landlord's consent or approval to any such
holdover, nor operate to preclude or inhibit the exercise by Landlord of all of
its rights and remedies hereunder or available under applicable law to
dispossess or evict Tenant. There shall be no renewal of this Lease by operation
of law.

      8.5 BROKERS: Except with respect to Landlord's Broker (whose commission
Landlord shall pay) and Tenant's Broker, if any, (to whom Landlord's Broker is
obligated to pay a portion of such commission in accordance with a separate
written agreement between Landlord's Broker and Tenant's Broker), Tenant and
Landlord each represents and warrants to the other that no broker, agent,
commission salesman or other person has represented the warranting party in the
negotiations for and procurement of this Lease and of the Premises, and that no
commissions, fees or compensation of any kind are due and payable in connection
herewith to any such person or entity. The individual(s) executing this
Agreement on behalf of Tenant hereby swear to and for the benefit of Landlord,
any lender of Landlord holding a lien or security title interest in and to all
or any portion of the Building, any attorney certifying title to the Building
and any title insurance company insuring title to all or any portion of the
Building that (a) except for Tenant's Broker, if any, (i) all fees, commissions,
compensation or other amounts payable to any and all real estate brokers engaged
by Tenant in connection with the Lease have been paid in full, or (ii) the
rights of any and all real estate brokers engaged by Tenant to file any lien,
notice of lien or claim of lien under O.C.G.A. Section 44-14-600 et seq. have
been waived in writing by such broker, and (b) except for the commission payable
by

Landlord to Tenant's Broker, in accordance with the separate written agreement
between Landlord's Broker and Tenant's Broker, if any, all fees, commissions,
compensation or other amounts payable to Tenant's Broker in connection with this
Agreement have been paid in full. Each party further warrants that any
compensation arrangement with the parties excepted from the foregoing warranty
has been reduced to writing in its entirety in a separate agreement signed
simultaneously with or before this Lease by the party against whom the
commission or compensation is charged. Each party agrees to indemnify and hold
the other harmless from and against any claim for any such commissions, fees, or
other form of compensation by any such third party claiming through the
indemnifying party, including, without limitation, any and all claims, causes of
action, damages, costs and expenses (including attorneys' fees) associated
therewith.

      8.6 WAIVER OF RIGHTS: No failure or delay by Landlord to exercise any
right or power given it or to insist upon strict compliance by Tenant with any
obligation imposed on it, and no custom or practice of either party hereto at
variance with any term hereof shall constitute a waiver or a modification of the
terms hereof by Landlord or any right it has herein to demand strict compliance
with the terms hereof by Tenant. This Lease contains the sole and entire
Agreement of Landlord and Tenant and no prior or contemporaneous oral or written
representation or agreement between the parties and affecting the Premises shall
have legal effect. No representative, agent or employee of Landlord has or shall
have any authority to waive any provision of this Lease unless such waiver is
expressly made in writing and signed by an authorized representative of
Landlord.

      8.7 WAIVER OF HOMESTEAD AND EXEMPTION: BANKRUPTCY OF TENANT:

            (a) Tenant hereby waives and renounces all homestead or exemption
rights which Tenant may have under or by virtue of the Constitution and Laws of
the United States, Georgia, or any other State as against any debt Tenant may
owe Landlord under this Lease, and hereby transfers, conveys, and assigns to
Landlord all homestead or exemption rights which may be allowed or set apart to
Tenant, including such as may be set apart in any bankruptcy proceeding, to pay
any debt owing by Tenant to Landlord hereunder.

            (b) Tenant acknowledges that this Lease is a lease of nonresidential
real property and therefore agrees that Tenant, as the debtor in possession, or
the trustee for Tenant (collectively, the "Trustee") in any proceeding under
Title 11 of the United States Bankruptcy Code, as amended (the "Bankruptcy
Code"), relating to bankruptcy, shall not seek or request any extension of time
to assume or reject this Lease or to perform any obligations of this Lease which
arise from or after the order of relief. Further, Tenant agrees as follows:

                  (i) If the Trustee proposes to assume or to assign this Lease
or sublet the Premises (or any portion thereof) to any person or entity which
shall have made a bona fide offer to accept an assignment of this Lease or a
subletting on terms acceptable to the Trustee, then the Trustee shall give
written notice to Landlord and any Mortgagee of which Tenant has notice, setting
forth the name and address of such person or entity and the terms and conditions
of such offer, no later than twenty (20) days after receipt of such offer, but
in any event no later than ten (10) days prior to the date on which the Trustee
makes application to the Bankruptcy Court for authority and approval to enter
into such assumption and assignment or subletting. Landlord shall have the prior
right and option, to be exercised by written notice to the Trustee given at any
time prior to the effective date of such proposed assignment or subletting, to
accept an assignment of this Lease or subletting of the Premises upon the same
terms and conditions and for the same consideration, if any, as the bonafide
offer made by such person or entity, less any brokerage commissions which may be
payable out of the consideration to be paid by such person or entity for the
assignment or subletting of this Lease.

                  (ii) The Trustee shall have the right to assume Tenant's
rights and obligations under this Lease only if the Trustee: (i) promptly cures
or provides adequate assurance that the Trustee will promptly cure any default
under the Lease; (ii) compensates or provides adequate assurance that the
Trustee will promptly compensate Landlord for any actual pecuniary loss incurred
by Landlord as a result of Tenant's default under this Lease; and, (iii)
provides adequate assurance of future performance under the Lease. Adequate
assurance of future performance by any proposed assignee or subtenant shall
include, at a minimum, assurance that: (a) any proposed assignee or subtenant
shall deliver to Landlord a security deposit in an amount equal to at least
three (3) months' Base Rental accruing under the Lease; (b) any proposed
assignee or subtenant shall provide to Landlord an audited financial statement,
dated no later than six (6) months prior to the effective date of such proposed
assignment or sublease with no material change therein as of the effective date,
which financial statement shall show the proposed assignee or subtenant to have
a net worth equal to at least twelve (12) months' Base Rental accruing under the
Lease, or, in the alternative, the proposed assignee or subtenant shall provide
a guarantor of such proposed assignee's or subtenant's obligations under the
Lease, which guarantor shall provide an audited financial statement meeting the
requirements of this subpart and shall execute and deliver to Landlord a
guaranty agreement in form and substance acceptable to Landlord; and, (c) any
proposed assignee or subtenant shall grant to Landlord a security interest in
favor of Landlord in all furniture, fixtures, and other personal property to be
used by such proposed assignee or subtenant in the Premises. All payments of
Total Rent required of Tenant under this Lease, whether or not expressly
denominated as such in this Lease, shall constitute rent for the purposes of
Title 11 of the Bankruptcy Code.

                  (iii) For the purposes of the Bankruptcy Code relating to (i)
the obligation of the Trustee to provide adequate assurance that the Trustee
will "promptly" cure defaults and compensate for actual pecuniary loss, the word
"promptly" shall mean that cure of defaults and compensation will occur no later
than sixty (60) days following the filing of any motion or application to assume
this Lease; and (ii) the obligation of the Trustee to compensate or to provide
adequate assurance that the Trustee will promptly compensate Landlord for
"actual pecuniary loss" shall mean Landlord's damages upon default, including
but not limited to payments of past due Total Rent, including (without
limitation) interest at the rate provided for in Section 4.6(g), all attorneys'
fees, and all related costs and expenses of Landlord incurred in connection with
any default of Tenant and in connection with Tenant's bankruptcy proceedings.

                  (iv) Any person or entity to which this Lease is assigned
pursuant to the provisions of the Bankruptcy Code shall be deemed, without
further act or deed, to have assumed all of the obligations arising under this
Lease and each of the conditions and provisions hereof on and after the date of
such assignment. Any such assignee shall, upon the request of Landlord,
forthwith execute and deliver to Landlord an instrument, in form and substance
acceptable to Landlord, confirming such assumption.

      8.8 NO ESTATE IN LAND: RELATIONSHIP OF THE PARTIES: This Lease creates the
relationship of landlord and tenant between Landlord and Tenant. No estate shall
pass out of Landlord, and Tenant has only a usufruct which

<PAGE>

is not subject to levy and sale. Further, nothing contained herein shall be
deemed or construed by the parties hereto, or by any third party, as creating
the relationship of principal and agent, or of partnership, or of joint venture,
between the parties hereto, it being understood and agreed that no provision
contained herein, nor any acts of the parties hereto, shall be deemed to create
any relationship between such parties other than the relationship of landlord
and tenant.

      8.9 RECORDING: This Lease shall not be recorded by Tenant without
Landlord's consent endorsed hereon.

      8.10 GOVERNMENTAL REGULATIONS:

            (a) Tenant waives the benefits of all existing and future rent
control legislation and statutes and similar governmental rules and regulations,
whether in time of war or not, to the full extent permitted by law.

            (b) Except as provided in paragraph (c) of this Section 8.10, if, in
order to maintain the Building as an office building, or otherwise, or the
Premises for the use stipulated in Section 2.1, Landlord shall be required by
any governmental authority to repair, alter, remove, construct, reconstruct, or
improve any part or all of the Premises or the building, such action shall be
performed by Landlord but shall in no way affect Tenant's obligations under this
Lease. Tenant waives all claim for injury, damage or abatement of rent because
of such repair, alteration, removal, construction, reconstruction, or
improvement; provided, however, that if such action by Landlord renders the
Premises untenable, or if Landlord cannot reasonably complete such acts within
sixty (60) days after notice to it to perform such acts by the governmental
authority, either Landlord or Tenant, by written notice to the other delivered
not later than seventy (70) days after the date of notice to Landlord by such
governmental authority, may terminate this Lease, in which event Total Rent
shall be apportioned and paid up to and including the date the Premises become
untenable if terminated by Landlord, but up to and including the date of
termination if terminated by Tenant.

            (c) Without limiting the provisions of Section 4.6(d), Tenant shall,
at Tenant's sole cost and expense but subject to Landlord's prior written
approval, which approval shall not be unreasonably withheld, make each and every
alteration or addition to the Premises required to bring the Premises into
compliance with the requirements imposed by the Americans with Disabilities Act,
(42 U.S.C. Section 12101 et~q,) and any regulations promulgated pursuant
thereto ("ADA Requirements") effective from time to time during the Lease Term,
and any period of holding over by Tenant if:

                  (i) the requirement for such alteration or addition arises as
a result of:

                        (1)   any alteration or addition by Tenant; or

                        (2)   any violation by Tenant of any ADA Requirements;
                              or

                        (3)   a special use of the Premises or any part thereof
                              by Tenant or any assignee or subtenant of Tenant
                              (including, but not limited to, use for a facility
                              which constitutes, or, if open to the public
                              generally, would constitute, a "place of public
                              accommodation" under the ADA Requirements); or

                        (4)   the special needs of the employee(s) of Tenant or
                              any assignee or subtenant of Tenant; or

                  (ii) the ADA Requirements would otherwise make Tenant, rather
than Landlord, primarily responsible for making such alteration or addition.

      8.11 SUBORDINATION AND ATTORNMENT:

            (a) Except as provided in Subsection (c) below and subject to the
provisions of subsection (d) below, this Lease and all rights of Tenant
hereunder are and shall be subject and subordinate to the lien of Landlord's
Mortgage.

            (b) While Subsection (a) of this Section 8.11 is self-operative, and
no further instrument of subordination shall be necessary, Tenant shall, in
confirmation of such subordination, upon demand, at any time or times, execute,
acknowledge and deliver to Landlord or a holder of Landlord's Mortgage any and
all instruments requested by either of them to evidence such subordination.

            (c) Tenant shall, upon demand, at any time or times, execute,
acknowledge, and deliver to Landlord or to a holder of Landlord's Mortgage,
without expense, any and all instruments that may be necessary to make this
Lease superior to the lien of Landlord's Mortgage.

            (d) Tenant shall, at the option of any holder of Landlord's Mortgage
or any other purchaser at a foreclosure sale who shall hereafter succeed to the
rights of Landlord under this Lease (the "Purchaser"), attorn to and recognize
such Purchaser as Tenant's landlord under this Lease from and after the
foreclosure and for the balance of the Lease Term and shall promptly execute and
deliver any instrument that may be necessary to evidence such attornment. Upon
such attornment, this Lease shall continue in full force and effect as a direct
lease between such Purchaser and Tenant, subject to all of the terms, covenants
and conditions of this Lease; provided, however, that the Purchaser (including
its successors and assigns) shall not be (i) liable for any act or omission of
any prior Landlord under the Lease, (ii) subject to any offsets or defenses
which Tenant might have against any prior Landlord under the Lease, (iii) bound
by any Base Rental or other payments which Tenant might have paid for more than
the current month to any prior Landlord under the Lease, or (iv) bound by any
amendment or modification of the Lease made after the date of the foreclosed
Landlord's Mortgage without the prior written consent of the Mortgagee
thereunder. The provisions of this subsection (d) shall survive any termination
of this Lease resulting from a foreclosure of Landlord's Mortgage.

            (e) If Tenant fails at any time to execute, acknowledge and deliver
any of the instruments provided for by Subsections 8.11(b), (c) and (d) above
within ten (10) days after Landlord's demand so to do, Landlord, in addition to
the

<PAGE>

remedies allowed by Article VI, may execute, acknowledge and deliver any and all
of such instruments as the attorney-in-fact of Tenant and in its name, place and
stead, and Tenant hereby irrevocably appoints Landlord, its successors and
assigns, as such attorney-in-fact.

      8.12 ESTOPPEL CERTIFICATE: At any time and from time to time, Tenant, on
or before the date specified in a request therefor made by Landlord, which date
shall not be earlier than ten (10) days from the making of such request, shall
execute, acknowledge and deliver to Landlord a certificate in substantially the
same form as the Estoppel Certificate which is attached hereto as Exhibit "G"
and incorporated herein by reference. Each certificate delivered pursuant to
this Section may be relied on by any prospective purchaser or transferee of
Landlord's interest hereunder or of any part of Landlord's property or by any
holder or prospective holder of Landlord's Mortgage, or a mortgage or
prospective mortgage of any part of Landlord's other property.

      8.13 SEVERABILITY: Each clause and provision of this Lease shall be valid
and enforced to the fullest extent permitted by applicable law; however, if any
clause or provision of this Lease is or becomes illegal, invalid, or
unenforceable because of present or future laws or any rule or regulation of any
governmental body or entity, effective during its term, the intention of the
parties hereto is that the remaining parts of this Lease and the application of
such clause or provision to persons or circumstances other than those as to
which it is held invalid or unenforceable, shall not be affected thereby, unless
the amount of Total Rent payable hereunder is thereby decreased, in which event
Landlord may terminate this Lease. Should any of the provisions of this Lease
require judicial interpretation, it is agreed that the court interpreting or
construing the same shall not apply a presumption that the terms of any such
provision shall be more strictly construed against one party by reason of any
rule of construction that a document is to be construed most strictly against
the party who itself or through its agent prepared the same, it being agreed
that the agents of all parties have participated in the negotiation and
preparation of this Lease.

      8.14 CAPTIONS: The captions used in this Lease are for convenience only
and do not in any way limit or amplify the terms and provisions hereof.

      8.15 SUCCESSORS AND ASSIGNS: The provisions of this Lease shall inure to
the benefit of and be binding upon Landlord and Tenant, and their respective
successors, heirs, legal representatives and assigns, subject, however, in the
case of Tenant, to the provisions of Article V.

      8.16 SALE OF BUILDING: In the event of any sale or sales of the Building
(and the property on which same is situated) or of any lease thereof, the
Landlord named herein above shall be and hereby is entirely freed and relieved
of all covenants and obligations of Landlord hereunder accruing thereafter, and
it shall be deemed without further agreement that the purchaser, or the lessee,
as the case may be, has assumed and agreed to carry out any and all covenants
and obligations of Landlord hereunder during the period such party has
possession of the Building. Should the entire Building and the property on which
same is situated be severed as to ownership by sale and/or lease, then the owner
of the entire Building or the lessee of the entire Building that has the right
to lease space in the Building to tenants shall be deemed the "Landlord". Tenant
shall be bound to any succeeding Landlord for all the terms, covenants and
conditions hereof and shall execute any attornment agreement not in conflict
herewith at the request of any succeeding Landlord. The provisions of this
Section 8.16 shall apply to each and every sale, lease or other transfer of the
Building or the property on which same is situated, or both, during the Lease
Term.

      8.17 TRANSFER OF TENANTS: This Section 8.17 shall only be effective at
such times and from time to time as the Premises contain a rentable area of
3,000 square feet or less. Landlord hereby reserves the right, at its sole
option and upon giving at least sixty (60) calendar days written notice in
advance to Tenant, to transfer and remove Tenant from the Premises from time to
time to any other available space in the Tower Place Complex of substantially
equal area, which space shall, once Tenant has been relocated therein, be deemed
the "Premises" for purposes of this Lease. Landlord hereby agrees to bear the
expense of such transfer and removal, as well as the expense of any renovations
or alterations which are necessary to make the new space conform substantially
in layout and appointment with the Premises. Failure of Tenant to cooperate with
Landlord pursuant to this provision and to remove itself from the Premises shall
permit Landlord to enter the Premises and to remove Tenant and its property
therefrom and to relocate Tenant and its property in the new space provided by
Landlord pursuant to this provision, all without being liable to Tenant in any
manner whatsoever for such acts, except for the expenses which are expressly
provided in this Section 8.17 to be paid by Landlord.

      8.18 GOVERNING LAW: The laws of the State of Georgia shall govern the
interpretation, validity, performance and enforcement of this Lease.

      8.19 TIME IS OF THE ESSENCE: Except as otherwise specifically provided
herein, time is of the essence of this Lease.

      8.20 LIMITATION OF LIABILITY: Landlords obligations and liability to
Tenant with respect to this Lease shall be limited solely to Landlord's interest
in the Building, and Tenant shall look solely to Landlord's interest in the
Building for satisfaction of Tenant's remedies. Neither Landlord nor any
partner, officer, director, or shareholder of Landlord or of any partner of
Landlord shall have any personal liability whatsoever with respect to this
Lease.

      8.21 EXECUTION: This Lease may be executed in any number of counterparts,
each of which shall be deemed an original and any of which shall be deemed to be
complete in itself and shall be admissible into evidence or used for any purpose
without the production of the other counterparts.

      8.22 MULTIPLE/TENANTS: If Tenant is composed of more than one individual
or entity, then all are jointly and severally liable for the due and proper
performance of Tenant's duties and obligations arising under or in connection
with this Lease.

      8.23 FORCE MAJEURE: Landlord shall be excused from the performance of any
of its obligations for the period of any delay resulting from any cause beyond
its control, including, without limitation, all labor disputes, governmental
regulations or controls, fires or other casualties, inability to obtain any
material or services, or acts of God.

      8.24 QUIET ENJOYMENT: Provided that Tenant fully and timely performs all
the terms of this Lease on Tenant's part to be performed, including payment by
Tenant of all Total Rent, Tenant shall have, hold and enjoy the Premises

<PAGE>

during the Lease Term without hindrance or disturbance from or by Landlord;
subject, however, to all of the terms, conditions and provisions of this Lease,
Landlord's Mortgage and any and all ground leases, restrictive covenants,
easements, and other encumbrances now or hereafter affecting the Premises, the
Building or the Tower Place Complex (if applicable).

      8.25 ATTORNEYS' FEES: If any rent or other amount owing by Tenant to
Landlord under this Lease is collected by or through an attorney at law, Tenant
agrees so pay an additional amount equal to fifteen percent (15%) of such sum as
attorneys' fees.

      8.26 ALTERATIONS IN COMPOSITION OF COMMON AREAS: Landlord reserves the
right in its sole discretion to redesign, change, rearrange, alter, reconstruct,
modify, expand, reduce or supplement any and all of the facilities designed for
the common use and convenience of all tenants of the Tower Place Complex and/or
the Building, including, without limitation, parking areas, driveways and other
the Common Areas, so long as access to the Premises is not materially adversely
affected thereby. In furtherance, and not in limitation, of the foregoing,
Landlord shall have the right to erect additional stores or other structures in
the Tower Place Complex, or to add to or otherwise modify buildings and
facilities now or hereafter existing in the Tower Place Complex, and, in
connection with any such activity and construction, to erect temporary scaffolds
and other aids to construction on the exterior of the Premises, provided that
access to the Premises shall not be denied Tenant and that there shall be no
encroachment upon the interior of the Premises. Landlord shall have the right to
close the Common Areas or any portion thereof (including, without limitation,
all roadways, driveways, accessways, sidewalks and parking areas and facilities
now or hereafter within the Tower Place Complex) at such time and in such manner
as is necessary or appropriate, in Landlord's sole opinion, to prevent their
deduction as public rights-of-way or streets, and to do and perform such other
acts in, to and with respect to the Common Areas as at the time in question
accord with good and generally accepted standards of operation of mixed-use,
high-rise developments.

      8.27 PARKING: Tenant shall have the right on the Commencement Date to
lease parking spaces in the parking facilities of the Tower Place Complex
available to tenants therein (as same may be modified from time to time) up to
the maximum number of parking spaces stipulated in Section 1.1(r). All of such
spaces shall be unassigned and shall be leased at the posted monthly rental
rates in effect therefor from time to time. * Landlord and Tenant agree and
Tenant acknowledges that rates for spaces in the parking facilities of the Tower
Place Complex may vary according to the location of spaces in the facilities and
according to whether or not spaces are reserved or unreserved. Tenant further
acknowledges and agrees that Landlord may designate certain spaces within the
parking facilities of the Tower Place Complex as reserved or assigned spaces for
the benefit of Landlord, visitors to the project or tenants therein, other
tenants, couriers and delivery services and other persons. Tenant shall comply
and cause its employees to complete and sign the Tower Place Parking
Application. Tenant must comply with all rules and regulations established by
Landlord and/or the operator of the parking facilities as provided in the Tower
Place Parking Rules and Regulations, including, without limitation, any card,
sticker or other identification system, whether now or hereafter in effect, and
agrees to pay to Landlord a fifteen dollar ($15.00) or as modified from time to
time deposit for each parking card issued. All parking privileges granted
pursuant to this Section 8.27 are non-assignable and nontransferable by Tenant;
provided however, that parking privileges may be assigned or transferred by
Tenant in conjunction with a transfer, assignment or subletting allowed by
Article V of this Lease. Tenant agrees to pay, as additional rent, the sum of
$15.00 for any parking cards which become lost, mutilated or destroyed.

      8.28 SPECIAL STIPULATIONS: The Special Stipulations, if any, attached
hereto are made a part hereof by this reference, and to the extent they conflict
with any of the foregoing provisions, they shall control.

      8.29 AUTHORIZATION: As a material inducement to Landlord to enter into
this Lease, Tenant, and each party executing this Lease on behalf of Tenant,
intending that Landlord rely on each such representation and warranty,
represents and warrants to Landlord that:

            (a) the execution, delivery and full performance of this Lease by
Tenant do not and shall not constitute a violation of any contract, agreement,
undertaking, judgment, statute, regulation, governmental or court order or other
restriction of any kind to which Tenant is a party or by which Tenant is or may
be bound;

            (b) Tenant has executed and entered into this Lease free from fraud,

Lease in accordance with the terms hereof, and to transact business in the State
of Georgia; and

            (e) the execution and delivery of this Lease by the individual or
individuals executing this Lease on behalf of Tenant, and Tenant's performance
of its obligations under this Lease, have been duly authorized and approved by

                                  WORK SCHEDULE

                                       TO
                            TOWER PLACE OFFICE LEASE
                                 by and between
                                TOWER PLACE, L.P.
                                       and
                              QUALITY SYSTEMS, INC.

      1. Premises Leased "As Is". Tenant and Landlord agree and Tenant
acknowledges that the Premises are in all respects being leased by Landlord to
Tenant, and shall be accepted by Tenant, in their current "AS IS/WHERE IS"
condition and that Landlord has and shall have no obligation or duty whatsoever
to make any alterations, repairs or improvements of any kind or nature in or to
the Premises in order to prepare same for Tenant's occupancy, except for such
alterations, repairs or improvements, if any, as may be expressly provided in
Paragraph 2 below.

      2. Landlord's Work. Landlord, at its sole cost and expense, agrees to make
the following modifications to the Premises in accordance with Exhibit "E-1".

      3. Delays in Occupancy. If for any reason, other than Tenant delay as
described in Paragraph 4 below, Landlord cannot or is unable to deliver
possession of the Premises to Tenant on or before the Anticipated Commencement
Date in accordance with and in the condition required by this Work Schedule and
the Lease, the Lease shall not be void or voidable except as provided in the
following sentence, and Landlord shall not be liable to Tenant for any loss or
damage resulting from Landlord's failure or delay in so delivering possession of
the Premises, but in such case (and subject to Paragraph 4 below) the
Commencement Date shall not occur until Landlord is able to deliver the Premises
in the condition required by this Lease; the Expiration Date, however, shall not
otherwise be affected by such delay. Further, if for any reason other than
strikes, casualties, Tenant delay, or other causes beyond the control of
Landlord, possession of the Premises is not delivered to Tenant within ninety
(90) days after the Anticipated Commencement Date, or if possession is not so
delivered for any reason whatsoever other than Tenant delay on or before six (6)
months following the Anticipated Commencement Date, then this Lease shall be
voidable by either party upon thirty (30) days' written notice to the other
given at any time prior to delivery of possession in accordance with this Work
Schedule and the Lease, provided that such notice shall be void if possession is
delivered within said thirty (30) day period. If the Lease is voided pursuant to
this provision, then any monies advanced by Tenant to Landlord shall be returned
and the parties hereto shall have no further rights, claims or obligations under
the Lease.

      4. Tenant Delays. If on the Anticipated Commencement Date Landlord is
unable to deliver the Premises to Tenant in accordance with and in the condition
required by this Work Schedule and the Lease due to omission, delay or default
by Tenant or anyone acting under or for Tenant ("Tenant delay"), then Tenant's
obligations under this Lease (including, without limitation, the obligation to
pay Total Rent) shall nonetheless commence as of the Anticipated Commencement
Date (which shall in such case be the Commencement Date), except that, in the
event that Landlord cannot deliver possession of the Premises to Tenant on the
Anticipated Commencement Date because of Tenant delay, this Lease shall be
voidable at the sole option of Landlord at any time prior to Tenant's
performance of such obligations or payment of the Total Rent due under this
Lease; and, should Landlord so elect to void this Lease, all monies advanced by
Tenant to Landlord shall be retained by Landlord as liquidated damages (the
parties hereto recognizing and acknowledging the difficulty of determining
such damages), and thereafter the parties hereto shall have no further rights,
claims, or obligations under this Lease, except for such matters which by the
express terms of the Lease survive expiration or termination thereof.

possession of the Premises to Lessee. If possession of the Premises is not
delivered to Lessee within sixty (60) days after the Commencement Date, Lessee
may, at its option, by notice in writing to Lessor within ten (10) days after
the end of said sixty (60) day period, cancel this Lease, in which event the
parties shall be discharged from all obligations hereunder; provided further,
however, that if such written notice of Lessee is not received by Lessor within
said ten (10) day period, Lessee's right to cancel this Lease hereunder shall
terminate and be of no further force or effect. Except as may be otherwise
provided, and regardless of when the Original Term actually commences, if
possession is not tendered to Lessee when required by this Lease and Lessee does
not terminate this Lease, as aforesaid, the period free of the obligation to pay
Base Rent, if any, that Lessee would otherwise have enjoyed shall run from the
date of delivery of possession and continue for a period equal to the period
during which the Lessee would have otherwise enjoyed under the terms hereof, but
minus any days of delay caused by the acts, changes or omissions of Lessee.

the same may be adjusted from time to time, to Lessor in lawful money of the
United States, without offset or deduction, on or before the day on which it is
due under the terms of this Lease. Base Rent and all other rent and charges for
any period during the term hereof which is for less than one full month shall be
prorated based upon the actual number of days of the month involved. Payment of
Base Rent and other charges shall be made to Lessor at its address stated herein
or to such other persons or at such other addresses as Lessor may from time to
time designate in writing to Lessee.

      *4.2 Common Area Operating Expenses. Lessee shall pay to Lessor during the
term hereof, in addition to the Base Rent, Lessee's Share (as specified in
Paragraph 1.6(b)) of all Common Area Operating Expenses, as hereinafter defined,
during each calendar year of the term of this Lease, in accordance with the
following provisions: * Common Area Operating Expense cost shall be $0.05 per

buildings in the Industrial Center.

            (c) The inclusion of the Improvements, facilities and services set
forth in Subparagraph 4.2(a) shall not be deemed to impose an obligation upon
[ILLEGIBLE] to either have said improvements or facilities or to provide those

provides the [ILLEGIBLE] or Lessor has agreed elsewhere in this Lease to provide
the same or some of them.

            (d) Lessee's Share of Common Area Operating Expenses shall be
payable by Lessee within ten (10) days after a reasonably detailed statement of
[ILLEGIBLE] expenses is presented to Lessee by Lessor. At Lessor's option,

all or any portion of said Security Deposit for the payment of any amount due
Lessor or to reimburse or compensate Lessor for any liability, cost, expense,
loss or damage (including attorneys' fees) which Lessor may suffer of incur by
reason thereof. If [ILLEGIBLE] uses or applies all or any portion of said
Security Deposit, Lessee shall within ten (10) days after written request

Lessor shall, at the expiration or earlier termination of the term hereof and
after Lessee has vacated the Premises, return to Lessee (or, at Lessor's option,
to the last assignee, if any, of Lessee's interest herein), that portion of the
Security Deposit not used or applied by Lessor. Unless otherwise expressly
agreed in writing by Lessor, no part of the Security Deposit shall be considered
to be held in trust, to bear interest or other Increment for its use, or to be
prepayment for any monies to be paid by Lessee under this Lease.

6. Use.

      6.1 Permitted Use.

            (a) Lessee shall use and occupy the Premises only for the Permitted
Use set forth in Paragraph 1.8, or any other legal use which is reasonably
comparable thereto, and for no other purpose. Lessee shall not use or permit the
use of the Premises in a manner that is unlawful, creates waste or a nuisance,
or that disturbs owners and/or occupants of, or causes damage to the Premises or
neighboring premises or properties.

            (b) Lessor hereby agrees to not unreasonably withhold or delay its
consent to any written request by Lessee. Lessee's assignees or subtenants, and
by prospective assignees and subtenants of Lessee, its assignees and subtenants,
for a modification of said Permitted Use, so long as the same will not impair
the structural integrity of the improvements on the Premises or in the Building
or the mechanical or electrical systems therein, does not conflict with uses by
other lessees, is not significantly more burdensome to the Premises or the
Building and the improvements thereon, and is otherwise permissible pursuant to
this Paragraph 6. If Lessor elects to withhold such consent, Lessor shall within
five (5) business days after such request give a written notification of same,
which notice shall include an explanation of Lessor's reasonable objections to
the change in use.

      6.2 Hazardous Substances.

            (a) Reportable Uses Require Consent. The term "Hazardous Substance"
as used in this Lease shall mean any product, substance, chemical, material or
waste whose presence, nature, quantity and/or intensity of existence, use,
manufacture, disposal, transportation, spill, release or effect, either by
itself or in combination with other materials expected to be on the Premises, is
either: (i) potentially injurious to the public health, safety or welfare, the
environment, or the Premises; (ii) regulated or monitored by any governmental
authority; or (iii) a basis for potential liability of Lessor to any
governmental agency or third party under any applicable statute or common law
theory. Hazardous Substance shall include, but not be limited to, hydrocarbons,
petroleum, gasoline, crude oil or any products or by-products thereof. Lessee
shall not engage in any activity in or about the Premises which constitutes a
Reportable Use (as hereinafter defined) of Hazardous Substances without the
express prior written consent of Lessor and compliance in a timely manner (at
Lessee's sole cost and expense) with all Applicable Requirements (as defined in
Paragraph 6.3). "Reportable Use" shall mean (i) the installation or use of any
above or below ground storage tank, (ii) the generation, possession, storage,
use, transportation, or disposal of a Hazardous Substance that requires a permit
from, or with respect to which a report, notice, registration or business plan
is required to be filed with, any governmental authority, and (iii) the presence
in, on or about the Premises of a Hazardous Substance with respect to which any
Applicable Laws require that a notice be given to persons entering or occupying
the Premises or neighboring properties. Notwithstanding the foregoing, Lessee
may, without Lessor's prior consent, but in compliance with all Applicable
Requirements, use any ordinary and customary materials reasonably required to be
used by Lessee in the normal course of the Permitted Use, so long as such use is
not a Reportable Use and does not expose the Premises or neighboring properties
to any meaningful risk of contamination or damage or expose Lessor to any
liability therefor. In addition, Lessor [ILLEGIBLE] without any obligation to do
so) condition its consent to any Reportable Use of any Hazardous Substance by
Lessee upon Lessee's giving Lessor such [ILLEGIBLE] assurances as Lessor, in its
reasonable discretion, deems necessary to protect itself, the public, the
Premises and the environment against damage, contamination or injury and/or
liability therefor, including but not limited to the installation (and, at
Lessor's option, removal on or before Lease expiration or earlier termination)
of reasonably necessary protective modifications to the Premises (such as
concrete encasements) and/or the deposit of an additional Security Deposit under
Paragraph 5 hereof.

Initials: [ILLEGIBLE]

            (b) Duty to Inform Lessor. If Lessee knows, or has reasonable cause
to believe, that a Hazardous Substance has come to be located in, on, under or
about the Premises or the Building, other than as previously consented to by
Lessor, Lessee shall immediately give Lessor written notice thereof, together
with a copy of any statement, report, notice, registration, application, permit,
business plan, license, claim, action, or proceeding given to, or received from,
any governmental authority or private party concerning the presence, spill,
release, discharge of, or exposure to, such Hazardous Substance including but
not limited to all such documents as may be involved in any Reportable Use
involving the Premises. Lessee shall not cause or permit any Hazardous Substance
to be spilled or released in, on, under or about the Premises (including,
without limitation, through the plumbing or sanitary sewer system).

            (c) Indemnification. Lessee shall indemnify, protect, defend and
hold Lessor, its agents, employees, lenders and ground lessor, if any, and the
Premises, harmless from and against any and all damages, liabilities, judgments,
costs, claims, liens, expenses, penalties, loss of permits and attorneys' and
consultants' fees arising out of or involving any Hazardous Substance brought
onto the Premises by or for Lessee or by anyone under Lessee's control. Lessee's
obligations under this Paragraph 6.2(c) shall include, but not be limited to,
the effects of any contamination or injury to person, property or the
environment created or suffered by Lessee, and the cost of Investigation
(including consultants' and attorneys' fees and testing), removal, remediation,
restoration and/or abatement thereof, or of any contamination therein involved,
and shall survive the expiration or earlier termination of this Lease. No
termination, cancellation or release agreement entered into by Lessor and Lessee
shall release Lessee from its obligations under this Lease with respect to
Hazardous Substances, unless specifically so agreed by Lessor in writing at the
time of such agreement.

            6.3 Lessee's Compliance with Requirements. Lessee shall, at Lessee's
sole cost and expense, fully, diligently and in a timely manner, comply with all
"Applicable Requirements," which term is used in this Lease to mean all laws,
rules, regulations, ordinances, directives, covenants, easements and
restrictions of record, permits, the requirements of any applicable fire
insurance underwriter or rating bureau, and the recommendations of Lessor's
engineers and/or consultants, relating in any manner to the Premises (including
but not limited to matters pertaining to (i) industrial hygiene, (ii)
environmental conditions on, in, under or about the Premises, including soil and
groundwater conditions, and (iii) the use, generation, manufacture, production,
installation, maintenance, removal, transportation, storage, spill, or release
of any Hazardous Substance), now in effect or which may hereafter come into
effect. Lessee shall, within five (5) days after receipt of Lessor's written
request, provide Lessor with copies of all documents and information, including
but not limited to permits, registrations, manifests, applications, reports and
certificates, evidencing Lessee's compliance with any Applicable Requirements
specified by Lessor, and shall immediately upon receipt, notify Lessor in
writing (with copies of any documents involved) of any threatened or actual
claim, notice, citation, warning, complaint or report pertaining to or involving
failure by Lessee or the Premises to comply with any Applicable Requirements.

            6.4 Inspection; Compliance with Law. Lessor, Lessor's agents,
employees, contractors and designated representatives, and the holders of any
mortgages, deeds of trust or ground leases on the Premises ("Lenders") shall
have the right to enter the Premises at any time in the case of an emergency,
and otherwise at reasonable times, for the purpose of inspecting the condition
of the Premises and for verifying compliance by Lessee with this Lease and all
Applicable Requirements (as defined in Paragraph 6.3), and Lessor shall be
entitled to employ experts and/or consultants in connection therewith to advise
Lessor with respect to Lessee's activities, including but not limited to
Lessee's installation, operation, use, monitoring, maintenance, or removal of
any Hazardous Substance on or from the Premises. The costs and expenses of any
such inspections shall be paid by the party requesting same, unless a Default or
Breach of this Lease by Lessee or a violation of Applicable Requirements or a
contamination, caused or materially contributed to by Lessee, is found to exist
or to be imminent, or unless [ILLEGIBLE] is requested or ordered by a
governmental authority as the result of any such existing or imminent violation
or contamination. In such case, Lessee [ILLEGIBLE] request reimburse Lessor or
Lessor's Lender, as the case may be, for the costs and expenses of such
inspections.

(Compliance with Covenants, Restrictions and Building Code), 7.2 (Lessor's
Obligations), 9 (Damage or Destruction), and 14 (Condemnation), Lessee shall, at
Lessee's sole cost and expense and at all times, keep the Premises and every
part thereof in good order, condition and repair (whether or not such portion of
the Premises requiring repair, or the means of repairing the same, are
reasonably or readily accessible to Lessee, and whether or not the need for such
repairs occurs as a result of Lessee's use, any prior use, the elements or the
age of such portion of the Premises), including, without limiting the generality
of the foregoing, all equipment or facilities specifically serving the Premises,
such as plumbing, heating, air conditioning, ventilating, electrical, lighting
facilities, boilers, fired or unfired pressure vessels, fire hose connections if
within the Premises, fixtures, interior walls, interior surfaces of exterior
walls, ceilings, floors, windows, doors, plate glass, and skylights, but
excluding any items which are the responsibility of Lessor pursuant to Paragraph
7.2 below. Lessee, in keeping the Premises in good order, condition and repair,
shall exercise and perform good maintenance practices. Lessee's obligations
shall include restorations, replacements or renewals when necessary to keep the
Premises and all improvements thereon or a part thereof in good order, condition
and state of repair.

            (b) Lessee shall, at Lessee's sole cost and expense, procure and
maintain a contract, with copies to Lessor, in customary form and substance for
and with a contractor specializing and experienced in the inspection,
maintenance and service of the heating, air conditioning and ventilation system
for the Premises. However, Lessor reserves the right, upon notice to Lessee, to
procure and maintain the contract for the heating, air conditioning and
ventilating systems. [ILLEGIBLE] Lessor so elects, Lessee shall reimburse
Lessor, upon demand, for the cost thereof.

            (c) If Lessee fails to perform Lessee's obligations under this
Paragraph 7.1, Lessor may enter upon the Premises after ten (10) days' prior

notice shall be required), perform such obligations on Lessee's behalf, and put
the [ILLEGIBLE] in good order, condition and repair, in accordance with

parkways, driveways, landscaping, fences, signs and utility systems serving the
Common Areas and all parts thereof, as well as providing the services for which
there is a Common Area Operating Expense pursuant to Paragraph 4.2. Lessor shall
not be obligated to paint the exterior or interior surfaces of exterior walls
nor shall Lessor be obligated to maintain, repair or replace windows, doors or
plate glass of the Premises. Lessee expressly waives the benefit of any statute
now or hereafter in effect which would otherwise afford Lessee the right to make
repairs at Lessor's expense or to terminate this Lease because of Lessor's
failure to keep the Building, Industrial Center or Common Areas in good order,
condition and repair.

      7.3 Utility Installations, Trade Fixtures, Alterations.

            (a) Definitions; Consent Required. The term "Utility Installations"
is used in this Lease to refer to all air lines, power panels, electrical
[ILLEGIBLE] security, fire protection systems, communications systems, lighting
fixtures, heating, ventilating and air conditioning equipment, plumbing, and
fencing in, on, or about the Premises. The term "Trade Fixtures" shall mean
Lessee's machinery and equipment which can be removed without doing material
damage to the Premises. The term "Alterations" shall mean any modification of
the improvements on the Premises which are provided by Lessor under the terms of
this Lease, other than Utility Installations or Trade Fixtures. "Leases-Owned
Alterations and/or Utility Installations" are defined as Alterations and/or
Utility Installations made by Lessee that are not yet owned by Lessor pursuant
to Paragraph 7.4(a). Lessee shall not make nor cause to be made any Alterations
or Utility Installations in, on, under or about the Premises without Lessor's
prior written consent. Lessee may, however, make non-structural Utility
Installations to the interior of the Premises (excluding the roof) without
Lessor's consent but upon notice to Lessor, so long as they are not visible from
the outside of the Premises, do involve puncturing, relocating or removing the
roof or any existing walls, or changing or interfering with the fire sprinkler
or fire detection systems and the cumulative cost thereof during the term of
this Lease as extended does not exceed $25,000

Initials [ILLEGIBLE]

            (b) Consent. Any Alterations or Utility Installations that Lessee
shall desire to make and which require the consent of the Lessor shall be
presented to Lessor in written form with detailed plans. All consents given by
Lessor, whether by virtue of Paragraph 7.3(a) or by subsequent specific consent,
shall be deemed conditioned upon: (i) Lessee's acquiring all applicable permits
required by governmental authorities; (ii) the furnishing of copies of such
permits together with a copy of the plans and specifications for the Alteration
or Utility Installation to Lessor prior to commencement of the work thereon; and
(iii) the compliance by Lessee with all conditions of said permits in a prompt
and expeditious manner. Any Alterations or Utility Installations by Lessee
during the term of this Lease shall be done in a good and workmanlike manner,
with good and sufficient materials, and be in compliance with all Applicable
Requirements. Lessee shall promptly upon completion thereof furnish Lessor with
as-built plans and specifications therefor. Lessor may, (but without obligation
to do so) condition its consent to any requested Alteration or Utility
installation that costs $25,000 or more upon Lessee's providing Lessor with a
lien and completion bond in an amount equal to one and one-half times the
estimated cost of such Alteration or Utility Installation.

            (c) Lien Protection. Lessee shall pay when due all claims for labor
or materials furnished or alleged to have been furnished to or for Lessee or for
use on the Premises, which claims are or may be secured by any mechanic's or
materialmen's lien against the Premises or any interest therein. Lessee shall
give Lessor not less than ten (10) days' notice prior to the commencement of any
work in, on, or about the Premises, and Lessor shall have the right to post
notices of non-responsibility in or on the Premises as provided by law. If
Lessee shall, in good faith, contest the validity of any such lien, claim or
demand, then Lessee shall, at its sole expense, defend and protect itself,
Lessor and the Premises against the same and shall pay and satisfy any such
adverse judgment that may be rendered thereon before the enforcement thereof
against the Lessor or the Premises. If Lessor shall require, Lessee shall
furnish to Lessor a surety bond satisfactory to Lessor in an amount equal to one
and one-half times the amount of such contested lien claim or demand,
indemnifying Lessor against liability for the same, as required by law for the
holding of the Premises free from the effect of such lien or claim. In addition,
Lessor may require Lessee to pay Lessor's reasonable attorneys' fees and costs
in participating in such action if Lessor shall decide it is to its best
interest to do so.

      7.4 Ownership, Removal, Surrender, and Restoration.

            (a) Ownership. Subject to Lessor's right to require their removal
and to cause Lessee to become the owner thereof as hereinafter provided in this
Paragraph 7.4, all Alterations and Utility Installations made to the Premises by
Lessee shall be the property of and owned by Lessee, but considered a part of
the Premises. Lessor may, at any time and at its option, elect in writing to
Lessee to be the owner of all or any specified part of the Lessee-Owned
Alterations and Utility Installations. Unless otherwise instructed per
Subparagraph 7.4(b) hereof, all Lessee-Owned Alterations and Utility
Installations shall, at the expiration or earlier termination of this Lease,
become the property of Lessor and remain upon the Premises and be surrendered
with the Premises by Lessee

            (b) Removal. Unless otherwise agreed in writing, Lessor may require
that any or all Lessee-Owned Alterations or Utility Installations be removed by
the expiration or earlier termination of this Lease, notwithstanding that their
Installation may have been consented to by Lessor. Lessor may require the
removal [ILLEGIBLE] time of all or any part of any Alterations or Utility
Installations made without the required consent of Lessor.

            (c) Surrender/Restoration. Lessee shall surrender the Premises by
the end of the last day of the Lease term or any earlier termination date, clean
and free of debris and in good operating order, condition and state of repair,
ordinary wear and tear excepted. Ordinary wear and tear shall not include any
damage or deterioration that would have been prevented by good maintenance
practice or by Lessee performing all of its obligations under this Lease. Except
as otherwise agreed or specified herein, the Premises, as surrendered, shall
include the Alterations and Utility Installations. The obligation of Lessee
shall include the repair of any damage occasioned by the installation,
maintenance or removal of Lessee's Trade Fixtures, furnishings, equipment, and
Lessee-Owned Alterations and Utility Installations, as well as the removal of
any storage tank installed by or for Lessee, and the removal, replacement, or
remediation of any soil, material or ground water contaminated by Lessee, all as
may then be required by Applicable Requirements and/or good practice. Lessee's
Trade Fixtures shall remain the property of Lessee and shall be removed by
Lessee subject to its obligation to repair and restore the Premises per this
Lease.

8. Insurance; Indemnity.

      8.1 Payment of Premiums. The cost of the premiums for the insurance
policies maintained by Lessor under this Paragraph 8 shall be a Common Area
Operating Expense pursuant to Paragraph 4.2 hereof. Premiums for policy periods
commencing prior to, or extending beyond, the term of this Lease shall be
prorated to coincide with the corresponding Commencement Date or Expiration
Date.

      8.2 Liability Insurance.

            (a) Carried by Lessee. Lessee shall obtain and keep in force during
the term of this Lease a Commercial General Liability policy of insurance
protecting Lessee, Lessor and any Lender(s) whose names have been provided to
Lessee in writing (as additional insureds) against claims for bodily injury,
personal injury and property damage based upon, involving or arising out of the
ownership, use, occupancy or maintenance of the Premises and all areas
appurtenant thereto. Such insurance shall be on an occurrence basis providing
single limit coverage in an amount not less than $1,000,000 per occurrence with
an "Additional Insured-Managers or Lessors of Premises" endorsement and contain
the "Amendment of the Pollution Exclusion" endorsement for damage caused by
heat, smoke or fumes from a hostile fire. The policy shall not contain any
intra-insured exclusions as between insured persons or organizations, but shall
include coverage for liability assumed under this Lease as an "Insured contract"
for the performance of Lessee's indemnity obligations under this Lease. The
limits of said insurance required by this Lease or as carried by Lessee shall
not, however, limit the liability of Lessee nor relieve Lessee of any obligation
hereunder. All insurance to be carried by Lessee shall be primary to and not
contributory with any similar insurance carried by Lessor, whose insurance shall
be considered excess insurance only.

            (b) Carried by Lessor. Lessor shall also maintain liability
insurance described in Paragraph 8.2(a) above, in addition to and not in lieu
of, the insurance required to be maintained by Lessee. Lessee shall not be named
as an additional insured therein.

      8.3 Property Insurance-Building, Improvements and Rental Value.

            (a) Building and Improvements. Lessor shall obtain and keep in force
during the term of this Lease a policy or policies in the name of Lessor, with
loss payable to Lessor and to any Lender(s), insuring against loss or damage to
the Premises. Such insurance shall be for full replacement cost, as the same
shall exist from time to time, or the amount required by any Lender(s), but in
no event more than the commercially reasonable and available insurable value
thereof if, by reason of the unique nature or age of the improvements involved,
such latter amount is less than full replacement cost. Lessee-Owned Alterations
and Utility Installations, Trade Fixtures and Lessee's personal property shall
be insured by Lessee pursuant to Paragraph 8.4. If the coverage is available and
commercially appropriate, Lessor's policy or policies shall insure against all
risks of direct physical loss or damage (except the perils of flood and/or
earthquake unless required by a Lender), including coverage for any additional
costs resulting from debris removal and reasonable amounts of coverage for the
enforcement of any ordinance or law regulating the reconstruction or replacement
of any undamaged sections of the Building required to be demolished or removed
by reason of the [ILLEGIBLE] cement of any building, zoning, safety or land use
laws as the result of a covered loss, but not including plate glass insurance.
Said policy or policies shall [ILLEGIBLE] contain an agreed valuation provision
in lieu of any co-insurance clause, waiver of subrogation, and inflation guard
protection causing an increase in the annual property insurance coverage amount
by a factor of not less than the adjusted U.S. Department of Labor Consumer
Price Index for All Urban Consumers for the city nearest to where the Premises
are located.

            (b) Rental Value. Lessor shall also obtain and keep in force during
the term of this Lease a policy or policies in the name of Lessor, with loss
payable to Lessor and any Lender(s), insuring the loss of the full rental and
other charges payable by all lessees of the Building to Lessor for one year
(including all Real Property Taxes, insurance costs, all Common Area Operating
Expenses and any scheduled rental increases). Said insurance may provide that in
the event the Lease is terminated by reason of an insured loss, the period of
indemnity for such coverage shall be extended beyond the date of the completion
of repairs or replacement of the Premises, to provide for one full year's loss
of rental revenues from the date of any such loss. Said insurance shall contain
an agreed valuation provision in lieu of any co-insurance clause, and the amount
of coverage shall be adjusted annually to reflect the projected rental income,

other buildings in the Industrial Center if said increase is caused by Lessee's
acts, omissions, use or occupancy of the Premises.

            (d) Lessee's Improvements. Since Lessor is the Insuring Party,
Lessor shall not be required to insure Lessee-Owned Alterations and Utility
Installations unless the item in question has become the property of Lessor
under the terms of this Lease.

      8.4 Lessee's Property Insurance. Subject to the requirements of Paragraph
8.5, Lessee at its cost shall either by separate policy or, at Lessor's
[ILLEGIBLE] by endorsement to a policy already carried, maintain insurance
coverage on all of Lessee's personal property, Trade Fixtures and Lessee-Owned
[ILLEGIBLE] and Utility Installations in, on, or about the Premises similar in
coverage to that carried by Lessor as the Insuring Party under Paragraph 8.3(a).
Such insurance shall be full replacement cost coverage with a deductible not to
exceed * * per occurrence. The proceeds from any such insurance shall be used by
Lessee for the replacement of personal property and the restoration of Trade
Fixtures and Lessee-Owned Alterations and Utility Installations. Upon request
from [ILLEGIBLE], Lessee shall provide Lessor with written evidence that such
insurance is in force. * *-$10,000

      8.5 Insurance Policies. Insurance required hereunder shall be in companies
duly licensed to transact business in the state where the Premises are located,

days after the earlier of the Early Possession Date or the Commencement Date,
certified copies of, or certificates evidencing the existence and amounts of,

perils required to be insured against under Paragraph 8. The effect of such
releases and waivers of the right to recover damages shall not be limited by the
amount of insurance carried or required, or by any deductibles applicable
thereto. Lessor and Lessee agree to have their respective insurance companies
issuing property damage insurance waive any right to subrogation that such
companies may have against Lessor or Lessee, as the case may be, so long as the
insurance is not invalidated thereby.

pursuit of any claim or any action or proceeding involved therein, and whether
or not (in the case of claims made against Lessor) litigated and/or reduced to
judgment. In case any action or proceeding be brought against Lessor by reason
of any of the foregoing matters, Lessee upon notice from Lessor shall defend the
same at Lessee's expense by counsel reasonably satisfactory to Lessor and Lessor
shall cooperate with Lessee in such defense. Lessor need not have first paid any
such claim in order to be so indemnified.

      8.8 Exemption of Lessor from Liability. Lessor shall not be liable for
injury or damage to the person or goods, wares, merchandise or other property of
Lessee, Lessee's employees, contractors, invitees, customers, or any other

results from fire, steam, electricity, gas, water or rain, or from the breakage,
leakage, obstruction or other defects of pipes, fire sprinklers, wires,
appliances, plumbing, air conditioning or lighting fixtures, or from any other
cause, whether said injury or damage results from conditions arising upon the

9. Damage or Destruction.

      9.1 Definitions.

            (a) "Premises Partial Damage" shall mean damage or destruction to
the Premises, other than Lessee-Owned Alterations and Utility Installations, the
repair cost of which damage or destruction is less than fifty percent (50%) of
the then Replacement Cost (as defined in Paragraph 9.1(d)) of the Premises
(excluding Lessee-Owned Alterations and Utility Installations and Trade
Fixtures) immediately prior to such damage or destruction.

            (b) "Premises Total Destruction" shall mean damage or destruction to
the Premises, other than Lessee-Owned Alterations and Utility Installations, the
repair cost of which damage or destruction is fifty percent (50%) or more of the
then Replacement Cost of the Premises (excluding Lessee-Owned Alterations and
Utility Installations and Trade Fixtures) immediately prior to such damage or
destruction. In addition, damage or destruction to the Building, other than
Lessee-Owned Alterations and Utility Installations and Trade Fixtures of any
lessees of the Building, the cost of which damage or destruction is fifty
percent (50%) or more of the then Replacement Cost (excluding Lessee-Owned
Alterations and Utility Installations and Trade Fixtures of any lessees of the
Building) of the Building shall, at the option of Lessor, be deemed to be
Premises Total Destruction.

            (c) "Insured Loss" shall mean damage or destruction to the Premises,
other than Lessee-Owned Alterations and Utility Installations and Trade
Fixtures, which was caused by an event required to be covered by the insurance
described in Paragraph 8.3(a) irrespective of any deductible amounts or coverage
[ILLEGIBLE] involved.

            (d) "Replacement Cost" shall mean the cost to repair or rebuild the
improvements owned by Lessor at the time of the occurrence to their condition
existing immediately prior thereto, including demolition, debris removal and
upgrading required by the operation of applicable building codes, ordinances or

            (e) "Hazardous Substance Condition" shall mean the occurrence or
discovery of a condition involving the presence of, or a contamination by, a
Hazardous Substance as defined in Paragraph 6.2(a), in, on, or under the

that is an Insured Loss occurs, then Lessor shall, at Lessor's expense, repair
such damage (but not Lessee's Trade Fixtures or Lessee-Owned Alterations and
Utility Installations) as soon as reasonably possible and this Lease shall
continue in full force and effect. In the event, however, that there is a
shortage of insurance proceeds and such shortage is due to the fact that, by
reason of the unique nature of the improvements in the Premises, full
replacement cost insurance coverage was not commercially reasonable and
available, Lessor shall have no obligation to pay for the shortage in insurance
proceeds or to fully restore the unique aspects of the Premises unless Lessee
provides Lessor with the funds to cover same, or adequate assurance thereof,
within ten (10) days following receipt of written notice of such shortage and
request therefor. If Lessor receives said funds or adequate assurance thereof
within said ten (10) day period, Lessor shall complete them as soon as
reasonably possible and this Lease shall remain in full force and effect. If
Lessor does not receive such funds or assurance within said period, Lessor may
nevertheless elect by written notice to Lessee within ten (10) days thereafter
to make such restoration and repair as is commercially reasonable with Lessor
paying any shortage in proceeds, in which case this Lease shall remain in full
force and effect. If Lessor does not receive such funds or assurance within such
ten (10) day period, and if Lessor does not so elect to restore and repair, then
this Lease shall terminate sixty (60) days following the occurrence of the
damage or destruction. Unless otherwise agreed, Lessee shall in no event have
any right to reimbursement from Lessor for any funds contributed by Lessee to
repair any such damage or destruction. Premises Partial Damage clue to flood or
earthquake shall be subject to Paragraph 9.3 rather than Paragraph 9.2,
notwithstanding that there may be some insurance coverage, but the net proceeds
of any such insurance shall be made available for the repairs if made by either
Party.

      9.3 Partial Damage - Uninsured Loss. If Premises Partial Damage that is
not an Insured Loss occurs, unless caused by a negligent or willful act of
Lessee (in which event Lessee shall make the repairs at Lessee's expense and
this Lease shall continue in full force and effect), Lessor may at Lessor's
option, either (i) repair such damage as soon as reasonably possible at Lessor's
expense, in which event this Lease shall continue in full force and effect, or
(ii) give written notice to Lessee within thirty (30) days after receipt by
Lessor of knowledge of the occurrence of such damage of Lessor's desire to
terminate this Lease as of the date sixty (60) days following the date of such
notice. In the event Lessor elects to give such notice of Lessor's intention to
terminate this Lease, Lessee shall have the right within ten (10) days after the
receipt of such notice to give written notice to Lessor of Lessee's commitment
to pay for the repair of such damage totally at Lessee's expense and without
reimbursement from Lessor. Lessee shall provide Lessor with the required funds
or satisfactory assurance thereof within thirty (30) days following such
commitment from Lessee. In such event this Lease shall continue in full force
and effect, and Lessor shall proceed to make such repairs as soon as reasonably
possible after the required funds are available. If Lessee does not give such
notice and provide the funds or assurance thereof within the times specified
above, this Lease shall terminate as of the date specified in Lessor's notice of
termination.

      9.4 Total Destruction. Notwithstanding any other provision hereof, if
Premises Total Destruction occurs (including any destruction required by any
authorized public authority), this Lease shall terminate sixty (60) days
following the date of such Premises Total Destruction, whether or not the damage
or destruction is an Insured Loss or was caused by a negligent or willful act of
Lessee. In the event, however, that the damage or destruction was caused by
Lessee, Lessor shall have the right to recover Lessor's damages from Lessee
except as released and waived in Paragraph 9.7.

      9.5 Damage Near End of Term. If at any time during the last six (6) months
of the term of this Lease there is damage for which the cost to repair
[ILLEGIBLE] one month's Base Rent, whether or not an Insured Loss, Lessor may,
at Lessor's option, terminate this Lease effective sixty (60) days following the
date of occurrence of such damage by giving written notice to Lessee of Lessor's
election to do so within thirty (30) days after the date of occurrence of such
damage. Provided, however, if Lessee at that time has an exercisable option to
extend this Lease or to purchase the Premises, then Lessee may preserve this
Lease by (a) exercising such option, and (b) providing Lessor with any shortage
in insurance proceeds (or adequate assurance thereof) needed to make the repairs
on or before the earlier of (i) the date which is ten (10) days after Lessee's
receipt of Lessor's written notice purporting to terminate this Lease, or (ii)
the day prior to the date upon which such option expires. If Lessee duly
exercises such option during such period and provides Lessor with funds (or
adequate assurance thereof) to cover any shortage in insurance proceeds, Lessor
shall, at Lessor's expense repair such damage as soon as reasonably possible and
this Lease shall continue in full force and effect. If Lessee fails to exercise
such option and provide such funds or assurance during such period, then this
Lease shall terminate as of the date set forth in the first sentence of this
Paragraph 9.5.

      9.6 Abatement of Rent; Lessee's Remedies.

            (a) In the event of (i) Premises Partial Damage or (ii) Hazardous
Substance Condition for which Lessee is not legally responsible, the Base Rent,
Common Area Operating Expenses and other charges, if any, payable by Lessee
hereunder for the period during which such damage or condition, its repair,
remediation or restoration continues, shall be abated in proportion to the
degree to which Lessee's use of the Premises is impaired, but not in excess of
proceeds from insurance required to be carried under Paragraph 8.3(b). Except
for abatement of Base Rent, Common Area Operating Expenses and other charges, if
any, as aforesaid, all other obligations of Lessee hereunder shall be performed
by Lessee, and Lessee shall have no claim against Lessor for any damage suffered
by reason of any such damage, destruction, repair, remediation or restoration.

            (b) If Lessor shall be obligated to repair or restore the Premises
under the provisions of this Paragraph 9 and shall not commence, in a
substantial and meaningful way, the repair or restoration of the Premises within
ninety (90) days after such obligation shall accrue, Lessee may, at any time
prior to the commencement of such repair or restoration, give written notice to
Lessor and to any Lenders of which Lessee has actual notice of Lessee's election
to terminate [ILLEGIBLE] on a date not less than sixty (60) days following the
giving of such notice. If Lessee gives such notice to Lessor and such Lenders
and such repair or [ILLEGIBLE] is not commenced within thirty (30) days after
receipt of such notice, this Lease shall terminate as of the date specified in
said notice. If Lessor or a [ILLEGIBLE] commences the repair or restoration of
the Premises within thirty (30) days after the receipt of such notice, this
Lease shall continue in full force and effect. "Commence" as used in this
Paragraph 9.6 shall mean either the unconditional authorization of the
preparation of the required plans, or the beginning of the actual work on the
Premises, whichever occurs first.

      9.7 Hazardous Substance Conditions. If a Hazardous Substance Condition
occurs, unless Lessee is legally responsible therefor (in which case Lessee
shall make the investigation and remediation thereof required by Applicable
Requirements and this Lease shall continue in full force and effect, but subject

to Lessor's rights under Paragraph 6.2(c) and Paragraph 13), Lessor may at
Lessor's option either (i) investigate and remediate such Hazardous Substance
Condition, if required, as soon as reasonably possible at Lessor's expense, in
which event this Lease shall continue in full force and effect, or (ii) if the
estimated cost to investigate and remediate such condition exceeds twelve (12)
times the then monthly Base Rent or $100,000 whichever is greater, give written
notice to Lessee within thirty (30) days after receipt by Lessor of knowledge of
the occurrence of such Hazardous Substance Condition of Lessor's desire to
terminate this Lease as of the date sixty (60) days following the date of such
notice. In the event Lessor elects to give such notice of Lessor's intention to
terminate this Lease, Lessee shall have the right within ten (10) days after the
receipt of such notice to give written notice to Lessor of Lessee's commitment
to pay for the excess costs of (a) investigation and remediation of such
Hazardous Substance Condition to the extent required by Applicable Requirements,
over (b) an equal amount equal to twelve (12) times the then monthly Base Rent
or $100,000, whichever is greater. Lessee shall provide Lessor with the funds
required of Lessee or satisfactory [ILLEGIBLE] thereof within thirty (30) days
following said commitment by Lessee. In such event this Lease shall continue in
full force and effect, and Lessor shall [ILLEGIBLE] make such investigation and
remediation as soon as reasonably possible after the required funds are
available. If Lessee does not give such notice and provide the required funds or
assurance thereof within the time period specified above, this Lease shall
terminate as of the date specified in Lessor's notice of termination.

      9.8 Termination, Advance Payments. Upon termination of this Lease pursuant
to this Paragraph 9. Lessor shall return to Lessee any advance payment made by

      9.9 Waiver of Statutes. Lessor and Lessee agree that the terms of this
Lease shall govern the effect of any damage to or destruction of the Premises
and the Building with respect to the termination of this Lease and hereby waive
the provisions of any present or future statute to the extent it is inconsistent
herewith.

10. Real Property Taxes.

      10.1 Payment of Taxes. Lessor shall pay the Real Property Taxes, as
defined in Paragraph 10.2, applicable to the Industrial Center, and except as
otherwise provided in Paragraph 10.3, any such amounts shall be included in the
calculation of Common Area Operating Expenses in accordance with the provisions
of Paragraph 4.2.

      10.2 Real Property Tax Definition. As used herein, the term "Real Property
Taxes" shall include any form of real estate tax or assessment, general,
special, ordinary or extraordinary, and any license fee, commercial rental tax,
improvement bond or bonds, levy or tax (other than inheritance, personal income
or estate taxes) imposed upon the Industrial Center by any authority having the
direct or indirect power to tax, including any city, state or federal
government, or any school, agricultural, sanitary, fire, street, drainage, or
other improvement district thereof, levied against any legal or equitable
interest of Lessor in the Industrial Center or any portion thereof, Lessor's
right to rent or other income therefrom, and/or Lessor's business of leasing the
Premises. The term "Real Property Taxes" shall also include any tax, fee, levy,
assessment or charge, or any increase therein, imposed by reason of events
occurring, or changes in Applicable Law taking effect, during the term of this
Lease, including but not limited to a change in the ownership of the Industrial
Center or in the improvements thereon, the execution of this Lease, or any
modification, amendment or transfer thereof, and whether or not contemplated by
the Parties. In calculating Real Property Taxes for any calendar year, the Real
Property Taxes for any real estate tax year shall be included in the calculation
of Real Property Taxes for such calendar year based upon the number of days
which such calendar year and tax year have in common.

      10.3 Additional Improvements. Common Area Operating Expenses shall not
include Real Property Taxes specified in the tax assessor's records and work
sheets as being caused by additional improvements placed upon the industrial

Lessor at the time Common Area Operating Expenses are payable under Paragraph
4.2, the entirety of any increase in Real Property Taxes if assessed solely by
reason of Alterations, Trade Fixtures or Utility Installations placed upon the
Premises by Lessee or at Lessee's request.

      10.4 Joint Assessment. If the Building is not separately assessed, Real
Property Taxes allocated to the Building shall be an equitable proportion of the
Real Property Taxes for all of the land and improvements included within the tax
parcel assessed, such proportion to be determined by Lesser from the respective
valuations assigned in the assessor's work sheets or such other information as
may be reasonably available. Lessor's reasonable determination thereof, in good
faith, shall be conclusive.

      10.5 Lessee's Property Taxes. Lessee shall pay prior to delinquency all
taxes assessed against and levied upon Lessee-Owned Alterations and Utility
installations, Trade Fixtures, furnishings, equipment and all personal property
of Lessee contained in the Premises or stored within the Industrial Center. When
[ILLEGIBLE], Lessee shall cause its Lessee-Owned Alterations and Utility
Installations, Trade Fixtures, furnishings, equipment and all other personal
property to be [ILLEGIBLE] and billed separately from the real property of
Lessor. If any of Lessee's said property shall be assessed with Lessor's real
property, Lessee shall pay Lessor the taxes attributable to Lessee's property
within ten (10) days after receipt of a written statement setting forth the
taxes applicable to Lessee's property.

11. Utilities. Lessee shall pay directly for all utilities and services supplied
to the Premises, including but not limited to electricity, telephone, security,
gas and cleaning of the Premises, together with any taxes thereon. If any such
utilities or services are not separately metered to the Premises or separately
billed to the Premises, Lessee shall pay to Lessor a reasonable proportion to be
determined by Lessor of all such charges jointly metered or billed with other
premises in the Building, in the manner and within the time periods set forth in
Paragraph 4.2(d).

12. Assignment and Subletting.

      12.1 Lessor's Consent Required.

            (a) Lessee shall not voluntarily or by operation of law assign,
transfer, mortgage or otherwise transfer or encumber (collectively, "assign") or
sublet all or any part of Lessee's interest in this Lease or in the Premises
without Lessor's prior written consent given under and subject to the terms of
Paragraph 36.

            (b) A change in the control of Lessee shall constitute an assignment
requiring Lessor's consent. The transfer, on a cumulative basis, of twenty-five
percent (25%) or more of the voting control of Lessee shall constitute a change
in control for this purpose.

            (c) The involvement of Lessee or its assets in any transaction, or
series of transactions (by way of merger, sale, acquisition, financing,
refinancing, transfer, leveraged buy-out or otherwise), whether or not a formal
assignment or hypothecation of this Lease or Lessee's assets occurs, which
results or will result in a reduction of the Net Worth of Lessee, as hereinafter
defined, by an amount equal to or greater than twenty-five percent (25%) of such
Net Worth of Lessee as it was represented to Lessor at the time of full
execution and delivery of this Lease or at the time of the most recent
assignment to which Lessor has consented, or as it exists immediately prior to
said transaction or transactions constituting such reduction, at whichever time
said Net Worth of Lessee was or is greater, shall be considered an assignment of
this Lease by Lessee to which Lessor may reasonably withhold its consent. "Net
Worth of Lessee" for purposes of this Lease shall be the net worth of Lessee
(excluding any Guarantors) established under generally accepted accounting
principles consistently applied.

            (d) An assignment or subletting of Lessee's interest in this Lease
without Lessor's specific prior written consent shall, at Lessor's option, be a
Default curable after notice per Paragraph 13.1, or a non-curable Breach without
the necessity of any notice and grace period. If Lessor elects to treat such
unconsented to assignment or subletting as a non-curable Breach, Lessor shall
have the right to either: (i) terminate this Lease, or (ii) upon thirty (30)
days, written notice ("Lessor's Notice"), increase the monthly Base Rent for the
Premises to the greater of the then fair market rental value of the Premises, as
reasonably determined by Lessor, or one hundred ten percent (110%) of the Base
Rent then in effect, Pending determination of the new fair market rental value,
if disputed by Lessee, Lessee shall pay the amount set forth in Lessor's Notice,
with any overpayment credited against the next installment(s) of Base Rent
coming due, and any underpayment for the period retroactively to the effective
date of the adjustment being due and payable immediately upon the determination
thereof. Further, in the event of such Breach and rental adjustment, (i) the
purchase price of any option to purchase the Premises held by Lessee shall be
subject to similar adjustment to the then fair market value as reasonably
determined by Lessor (without the Lease being considered an encumbrance or any
deduction for depreciation or obsolescence, and considering the Premises at its
highest and best use and in good condition) or one hundred ten percent (110%) of
the price previously in effect, (ii) any index-oriented rental or price
adjustment formulas contained in this Lease shall be adjusted to require that
the base index be determined with reference to the index applicable to the time
of such adjustment, and (iii) any fixed rental adjustments scheduled during the
remainder of the Lease term shall be increased in the same ratio as the new
rental bears to the Base Rent in effect immediately prior to the adjustment
specified in Lessor's Notice.

            (e) Lessee's remedy for any beach of this Paragraph 12.1 by Lessor
shall be limited to compensatory damages and/or injunctive relief.

      12.2 Terms and Conditions Applicable to Assignment and Subletting.

            (a) Regardless of Lessor's consent, any assignment or subletting
shall not (i) be effective without the express written assumption by such
assignee or sublessee of the obligations of Lessee under this Lease, (ii)
release Lessee of any obligations hereunder, nor (iii) alter the primary
liability of Lessee for the payment of Base Rent and other sums due Lessor
hereunder or for the performance of any other obligations to be performed by
Lessee under this Lease.

            (b) Lessor may accept any rent or performance of Lessee's
obligations from any person other than Lessee pending approval or disapproval of
an assignment. Neither a delay in the approval or disapproval of such assignment
nor the acceptance of any rent for performance shall constitute a waiver or
estoppel of Lessor's right to exercise its remedies for the Default or Breach by
Lessee of any of the terms, covenants or conditions of this Lease.

            (c) The consent of Lessor to any assignment or subletting shall not
constitute a consent to any subsequent assignment or subletting by Lessee or to
any subsequent or successive assignment or subletting by the assignee or
sublessee. However, Lessor may consent to subsequent sublettings and assignments
of the sublease or any amendments or modifications thereto without notifying
Lessee or anyone else liable under this Lease or the sublease and without
obtaining their consent, and such action shall not relieve such persons from
liability under this Lease or the sublease.

            (d) In the event of any Default or Breach of Lessee's obligation
under this Lease, Lessor may proceed directly against Lessee, any Guarantors or
anyone else responsible for the performance of the Lessee's obligations under
this Lease, including any sublessee, without first exhausting Lessor's remedies
against any other person or entity responsible therefor to Lessor, or any
security held by Lessor.

            (e) Each request for consent to an assignment or subletting shall be
in writing, accompanied by information relevant to Lessor's determination as to
the financial and operational responsibility and appropriateness of the proposed
assignee or sublessee, including but not limited to the intended use and/or
[ILLEGIBLE] modification of the Premises, if any, together with a non-refundable
deposit of $1,000 or ten percent (10%) of the monthly Base Rent applicable to
the [ILLEGIBLE] the Premises which is the subject of the proposed assignment or
sublease, whichever is greater, as reasonable consideration for Lessor's
considering and [ILLEGIBLE] the request for consent. Lessee agrees to provide
Lessor with such other or additional information and/or documentation as may be
reasonably requested by Lessor.

            (f) Any assignee of, or sublessee under, this Lease shall, by reason
of accepting such assignment or entering into such sublease, be deemed,
[ILLEGIBLE] benefit of Lessor, to have assumed and agreed to conform and comply
with each and every term, covenant, condition and obligation herein to be
observed or performed by Lessee during the term of said assignment or sublease,
other than such obligations as are contrary to or inconsistent with provisions
of an assignment or sublease to which Lessor has specifically consented in
writing.

            (g) The occurrence of a transaction described in Paragraph 12.2(c)
shall give Lessor the right (but not the obligation) to require that the
Security Deposit be increased by an amount equal to six (6) times the then
monthly Base Rent, and Lessor may make the actual receipt by Lessor of the
Security Deposit Increase a condition to Lessor's consent to such transaction.

            (h) Lessor, as a condition to giving its consent to any assignment
or subletting, may require that the amount and adjustment schedule of the rent
payable under this Lease be adjusted to what is then the market value and/or
adjustment schedule for property similar to the Premises as then constituted, as
determined by Lessor.

      12.3 Additional Terms and Conditions Applicable to Subletting. The
following terms and conditions shall apply to any subletting by Lessee of all or
[ILLEGIBLE] of the Premises and shall be deemed included in all subleases under
this Lease whether or not expressly incorporated therein:

            (a) Lessee hereby assigns and transfers to Lessor all of Lessee's
interest in all rentals and income arising from any sublease of all or a portion
of the Premises heretofore or hereafter made by Lessee, and Lessor may collect
such rent and income and apply same toward Lessee's obligations under this
Lease; provided, however, that until a Breach (as defined in Paragraph 13.1)
shall occur in the performance of Lessee's obligations under this Lease. Lessee
may, except as otherwise provided in this Lease, receive, collect and enjoy the
rents accruing under such sublease. Lessor shall not, by reason of the foregoing
provision or any other assignment of such sublease to Lessor, nor by reason of
the collection of the rents from a sublessee, be deemed liable to the sublessee
for any failure of Lessee to perform and comply with any of Lessee's obligations
to such sublessee under such Sublease. Lessee hereby irrevocably authorizes and
directs any such sublessee, upon receipt of a written notice from Lessor stating
that a Breach exists in the performance of Lessee's obligations under this
Lease, to pay to Lessor the rents and other charges due and to become due under
the sublease. Sublessee shall rely upon any such statement and request from
Lessor and shall pay such rents and other charges to Lessor without any
obligation or right to inquire as to whether such Breach exists and
notwithstanding any notice from or claim from Lessee to the contrary. Lessee
shall have no right or claim against such sublessee, or, until the Breach has
been cured, against Lessor, for any such rents and other charges so paid by said
sublessee to Lessor.

            (b) In the event of a Breach by Lessee in the performance of its
obligations under this Lease, Lessor, at its option and without any obligation
to do so, may require any sublessee to attorn to Lessor, in which event Lessor
shall undertake the obligations of the sublessor under such sublease from the
time of the exercise of said option to the expiration of such sublease;
provided, however, Lessor shall not be liable for any prepaid rents or security
deposit paid by such sublessee to such sublessor or for any other prior defaults
or breaches of such sublessor under such sublease.

            (c) Any matter or thing requiring the consent of the sublessor under
a sublease shall also require the consent of Lessor herein.

            (d) No sublessee under a sublease approved by Lessor shall further
assign or sublet all or any part of the Premises without Lessor's prior written
consent.

            (e) Lessor shall deliver a copy of any notice of Default or Breach
by Lessee to the sublessee, who shall have the right to cure the Default of
Lessee within the grace period, if any, specified in such notice. The sublessee
shall have a right of reimbursement and offset from and against Lessee for any
such Defaults cured by the sublessee.

13. Default; Breach; Remedies.

      13.1 Default; Breach. Lessor and Lessee agree that if an attorney is
consulted by Lessor in connection with a Lessee Default or Breach (as
hereinafter defined), $350.00 is a reasonable minimum sum per such occurrence
for legal services and costs in the preparation and service of a notice of
Default, and that Lessor may include the cost of such services and costs in said
notice as rent due and payable to cure said default. A "Default" by Lessee is
defined as a failure by Lessee to observe, comply with or perform any of the
terms, covenants, conditions or rules applicable to Lessee under this Lease. A
"Breach" by Lessee is defined as the occurrence of any one or more of the
following Defaults, and, where a grace period for cure after notice is specified
herein, the failure by Lessee to cure such Default prior to the expiration of
the applicable grace period, and shall entitle Lessor to pursue the remedies set
forth in Paragraphs 13.2 and/or 13.3:

            (a) The vacating of the Premises without the intention to reoccupy
same, or the abandonment of the Premises.

            (b) Except as expressly otherwise provided in this Lease, the
failure by Lessee to make any payment of Base Rent, Lessee's Share of Common
Area Operating Expenses, or any other monetary payment required to be made by
Lessee hereunder as and when due, the failure by Lessee to provide Lessor
[ILLEGIBLE] evidence of insurance or surety bond required under this Lease, or
the failure of Lessee to fulfill any obligation under this Lease which endangers
[ILLEGIBLE] life or property, where such failure continues for a period of three
(3) days following written notice thereof by or on behalf of Lessor to Lessee.

            (c) Except as expressly otherwise provided in this Lease, the
failure by Lessee to provide Lessor with reasonable written evidence (in duty
executed original form, if applicable) of (i) compliance with Applicable
Requirements per Paragraph 6.3, (ii) the inspection, maintenance and service
contracts required under Paragraph 7.1(b), (iii) the rescission of an
unauthorized assignment or subletting per Paragraph 12.1, (iv) a Tenancy
Statement per Paragraphs 16 or 37, (v) the subordination or non-subordination of
this Lease per Paragraph 30, (vi) the guaranty of the performance of Lessee's
obligations under this Lease if required under Paragraphs 1.11 and 37, (vii) the
execution of any document requested under Paragraph 42 (easements), or (viii)
any other documentation or information which Lessor may reasonably require of
Lessee under the terms of this lease, where any such failure continues for a
period of ten (10) days following written notice by or on behalf of Lessor to
Lessee.

            (d) A Default by Lessee as to the terms, covenants, conditions or
provisions of this Lease, or of the rules adopted under Paragraph 40 hereof that
are to be observed, complied with or performed by Lessee, other than those
described in Subparagraphs 13.1(a), (b) or (c), above, where such Default
continues for a period of thirty (30) days after written notice thereof by or on
behalf of Lessor to Lessee; provided, however, that if the nature of Lessee's
Default is such that more than thirty (30) days are reasonably required for its
cure, then it shall not be deemed to be a Breach of this Lease by Lessee if
Lessee commences such cure within said thirty (30) day period and thereafter
diligently prosecutes such cure to completion.

            (e) The occurrence of any of the following events: (i) the making by
Lessee of any general arrangement or assignment for the benefit of creditors;
(ii) Lessee's becoming a "debtor" as defined in 11 U.S. Code Section 101 or any
successor statute thereto (unless, in the case of a petition filed against
Lessee, the same is dismissed within sixty (60) days); (iii) the appointment of
a trustee or receiver to take possession of substantially all of Lessee's assets
located at the Premises or of Lessee's interest in this Lease, where possession
is not restored to Lessee within thirty (30) days: or (iv) the attachment,
execution or other judicial seizure of substantially all of Lessee's assets
located at the Premises or of Lessee's interest in this Lease, where such
seizure is not discharged within thirty (30) days; provided, however, in the
event that any provision of this Subparagraph 13.1(e) is contrary to any
applicable law, such provision shall be of no force or effect, and shall not
affect the validity of the remaining provisions.

            (f) The discovery by Lessor that any financial statement of Lessee
or of any Guarantor, given to Lessor by Lessee or any Guarantor, was materially
false.

            (g) If the performance of Lessee's obligations under this Lease is
guaranteed: (i) the death of a Guarantor, (ii) the termination of a Guarantor's
liability with respect to this Lease other than in accordance with the terms of
such guaranty, (iii) a Guarantor's becoming insolvent or the subject of a
bankruptcy filing, (iv) a Guarantor's refusal to honor the guaranty, or (v) a
Guarantor's breach of its guaranty obligation on an anticipatory breach basis,
and Lessee's failure, within sixty (60) days following written notice by or on
behalf of Lessor to Lessee of any such event, to provide Lessor with written
alternative assurances of security, which, when coupled with the then existing
resources of Lessee, equals or exceeds the combined financial resources of
Lessee and the Guarantors that existed at the time of execution of this Lease.

      13.2 Remedies. If Lessee fails to perform any affirmative duty or
obligation of Lessee under this Lease, within ten (10) days after written notice
to Lessee (or in case of an emergency, without notice), Lessor may at its option
(but without obligation to do so), perform such duty or obligation on Lessee's
behalf, including but not limited to the obtaining of reasonably required bonds,
insurance policies, or governmental licenses, permits or approvals. The costs
and expenses of any such performance by Lessor shall be due and payable by
Lessee to Lessor upon invoice therefor. If any check given to Lessor by Lessee
shall not be honored by the bank upon which it is drawn, Lessor, at its own
option, may require all future payments to be made under this Lease by Lessee to
be made only by cashier's check. In the event of a Breach of this Lease by
Lessee (as defined in Paragraph 13.1), with or without further notice or demand,
and without limiting Lessor in the [ILLEGIBLE] of any right or remedy which
Lessor may have by reason of such Breach, Lessor may:

            (a) Terminate Lessee's right to possession of the Premises by any
lawful means, in which case this Lease and the term hereof shall terminate and
Lessee shall immediately surrender possession of the Premises to Lessor. In such
event Lessor shall be entitled to recover from Lessee: (i) the worth at the time
of the award of the unpaid rent which had been earned at the time of
termination; (ii) the worth at the time of award of the amount by which the
unpaid rent which would have been earned after termination until the time of
award exceeds the amount of such rental loss that the Lessee proves could have
been reasonably avoided; (iii) the worth at the time of award of the amount by
which the unpaid rent for the balance of the term after the time of award
exceeds the amount of such rental loss that the Lessee proves could be
reasonably avoided; and (iv) any other amount necessary to compensate Lessor for
all the detriment proximately caused by the Lessee's failure to perform its
obligations under this Lease or which in the ordinary course of things would be
likely to result therefrom including but not limited to the cost of recovering
possession of the Premises, expenses of reletting, including necessary
renovation and alteration of the Premises, reasonable attorneys' fees, and that
portion of any leasing commission paid by Lessor in connection with this Lease
applicable to the unexpired term of this Lease. The worth at the time of award
of the amount referred to in provision (iii) of the immediately preceding
sentence shall be computed by discounting such amount at the discount rate of
the Federal Reserve Bank of San Francisco or the Federal Reserve Bank District
in which the Premises are located at the time of award plus one percent (1%).
Efforts by Lessor to mitigate damages caused by Lessee's Default or Breach of
this Lease shall not waive Lessor's right to recover damages under this
Paragraph 13.2. If termination of this Lease is obtained through the provisional
remedy of unlawful detainer, Lessor shall have the right to recover in such
proceeding the unpaid rent and damages as are recoverable therein, or Lessor may
reserve the right to recover all or any part thereof in a separate suit for such
rent and/or damages. If a notice and grace period required under Subparagraph
13.1(b), (c) or (d) was not previously given, a notice to pay rent or quit, or
to perform or quit, as the case may be, given to Lessee under any statute
authorizing the forfeiture of leases for unlawful detainer shall also constitute
the applicable notice for grace period purposes required by Subparagraph
13.1(b), (c) or (d). In such case, the applicable grace period under the
unlawful detainer statue shall run concurrently after the one such statutory
notice, and the failure of Lessee to cure the Default within the greater of the
two (2) such grace periods shall constitute both an [ILLEGIBLE] detainer and a
Breach of this Lease entitling Lessor to the remedies provided for in this Lease
and/or by said statute.

            (b) Continue the Lease and Lessee's right to possession in effect
(in California under California Civil Code Section 1951.4) after Lessee's Breach
and recover the rent as it becomes due, provided Lessee has the right to sublet
or assign, subject only to reasonable limitations. Lessor and Lessee agree
[ILLEGIBLE] the limitations on assignment and subletting in this Lease are
reasonable. Acts of maintenance or preservation, efforts to relet the Premises,
or the appointment of a receiver to protect the Lessor's interest under this
Lease, shall not constitute a termination of the Lessee's right to possession.

            (c) Pursue any other remedy now or hereafter available to Lessor
under the laws or judicial decisions of the state wherein the Premise are
located.

<PAGE>

            (d) The expiration or termination of this Lease and/or the
termination of Lessee's right to possession shall not relieve Lessee from
liability under any indemnity provisions of this Lease as to matters occurring
or accruing during the term hereof or by reason of Lessee's occupancy of the
Premises.

      13.3 inducement Recapture In Event of Breach. Any agreement by Lessor for
free or abated rent or other charges applicable to the Premises, or for the
giving or paying by Lessor to or for Lessee of any cash or other bonus,
inducement or consideration for Lessee's entering into this Lease, all of which
concessions are hereinafter referred to as "Inducement Provisions" shall be
deemed conditioned upon Lessee's full and faithful performance of all of the
terms, covenants and conditions of this Lease to be performed or observed by
Lessee during the term hereof as the same may be extended. Upon the occurrence
of a Breach (as defined in Paragraph 13,1) of this Lease by Lessee, any such
Inducement Provision shall automatically be deemed deleted from this Lease and
of no [ILLEGIBLE] force or effect, and any rent, other charge, bonus, inducement
or consideration theretofore abated, given or paid by Lessor under such an
Inducement [ILLEGIBLE] shall be immediately due and payable by Lessee to Lessor,
and recoverable by Lessor, as additional rent due under this Lease,
notwithstanding any subsequent cure of said Breach by Lessee. The acceptance by
Lessor of rent or the cure of the Breach which Initiated the operation of this
Paragraph 13.3 shall not be deemed a waiver by Lessor of the provisions of this
Paragraph 13.3 unless specifically so stated in writing by Lessor at the time of
such acceptance.

      13.4 Late Charges. Lessee hereby acknowledges that late payment by Lessee
to Lessor of rent and other sums due hereunder will cause Lessor to incur costs
not contemplated by this Lease, the exact amount of which will be extremely
difficult to ascertain. Such costs include, but are not limited to, processing
and accounting charges, and late charges which may be imposed upon Lessor by the
terms of any ground lease, mortgage or deed of trust covering the Premises.
Accordingly, if any installment of rent or other sum due from Lessee shall not
be received by Lessor or Lessor's designee within ten (10) days after such
amount shall be due, then, without any requirement for notice to Lessee, Lessee
shall pay to Lessor a late charge equal to six percent (6%) of such overdue
amount. The parties hereby agree that such late charge represents a fair and
reasonable estimate of the costs Lessor will incur by reason of late payment by
Lessee Acceptance of such late charge by Lessor shall in no event constitute a
waiver of Lessee's Default or Breach with respect to such overdue amount, nor
prevent Lessor from exercising any of the other rights and remedies granted
hereunder. In the event that a late charge is payable hereunder, whether or not
collected, for three (3) consecutive installments of Base Rent, then
notwithstanding Paragraph 4,1 or any other provision of this Lease to the
contrary, Base Rent shall, at Lessor's option, become due and payable quarterly
in advance.

      13.5 Breach by Lessor. Lessor shall not be deemed in breach of this Lease
unless Lessor fails within a reasonable time to perform an obligation required
to be performed by Lessor. For purposes of this Paragraph 13.5, a reasonable
time shall in no event be less than thirty (30) days after receipt by Lessor,
and by any Lender(s) whose name and address shall have been furnished to Lessee
in writing for such purpose, of written notice specifying wherein such
obligation of Lessor has not been performed; provided, however, that if the
nature of Lessor's obligation is such that more than thirty (30) days after such
notice are reasonably required for its performance, then Lessor shall not be in
breach of this Lease if performance is commenced within such thirty (30) day
period and thereafter diligently pursued to completion.

      14. Condemnation. If the Premises or any portion thereof are taken under
the power of eminent domain or sold under the threat of the exercise of said
power (all of which are herein called "condemnation"), this Lease shall
terminate as to the part so taken as of the date the condemning authority takes
title or possession, whichever first occurs. If more than ten percent (10%) of
the floor area of the Premises, or more than twenty-five percent (25%) of the
portion of the Common Areas designated for Lessee's parking, is taken by
condemnation, Lessee may, at Lessee's option, to be exercised in writing within
ten (10) days after Lessor shall have given Lessee written notice of such taking
(or in the absence of such notice, within ten (10) days after the condemning
authority shall have taken possession) terminate this Lease as of the date the
condemning authority takes such possession. If Lessee does not terminate this
Lease in accordance with the foregoing, this Lease shall remain in full force
and effect as to the portion of the Premises remaining, except that the Base
Rent shall be reduced in the same proportion as the rentable floor area of the
Premises taken bears to the total rentable floor area of the Premises. No
reduction of Base Rent shall occur if the condemnation does not apply to any
portion of the Premises. Any award for the taking of all or any part of the
Premises under the power of eminent domain or any payment made under threat of
the exercise of such power shall be the property of Lessor, whether such award
shall be made as compensation for diminution of value of the leasehold or for
the taking of the fee, or as severance damages: provided, however, that Lessee
shall be entitled to any compensation, separately awarded to Lessee for Lessee's
relocation expenses and/or loss of Lessee's Trade Fixtures. In the event that
this Lease is not terminated by reason of such condemnation, Lessor shall to the
extent of its net severance damages received, over and above Lessee's Share of
the legal and other expenses incurred by Lessor in the condemnation matter,
repair any damage to the Premises caused by such condemnation authority. Lessee
shall be responsible for the payment of any amount in excess of such net
severance damages required to complete such repair.

15. Brokers' Fees.

      15.1 Procuring Cause. The Broker(s) named in Paragraph 1.10 is/are the
procuring cause of this Lease.

      15.2 Additional Terms. Unless Lessor and Broker(s) have otherwise agreed
in writing, Lessor agrees that: (a) if Lessee exercises any Option (as defined
in Paragraph 39.1) granted under this Lease or any Option subsequently granted,
or (b) if Lessee acquires any rights to the Premises or other premises in which
Lessor has an interest, or (c) if Lessee remains in possession of the Premises
with the consent of Lessor after the expiration of the term of this Lease after
having failed to exercise an Option, or (d) if said Brokers are the procuring
cause of any other lease or sale entered into between the Parties pertaining to
the Premises and/or any adjacent property in which Lessor has an interest, or
(e) if Base Rent is increased, whether by agreement or operation of an
escalation clause herein, then as to any of said transactions, Lessor shall pay
said Broker(s) a fee in accordance with the schedule of said Broker(s) in effect
at the time of the execution of this Lease.

      15.3 Assumption of Obligations. Any buyer or transferee of Lessor's
interest in this Lease. whether such transfer is by agreement or by operation of
law, shall be deemed to have assumed Lessor's obligation under this Paragraph
15. Each Broker shall be an intended third party beneficiary of the provisions
of Paragraph 1,10 and of this Paragraph 15 to the extent of its interest in any
commission arising from this Lease and may enforce that right directly against
Lessor and its successors.

      15.4 Representations and Warranties. Lessee and Lessor each represent and
warrant to the other that it has had no dealings with any person, firm, broker
or finder other than as named in Paragraph 1.10(a) in connection with the
negotiation of this Lease and/or the consummation of the transaction
contemplated hereby, and that no broker or other person, firm or entity other
than said named Broker(s) is entitled to any commission or finder's fee in
connection with said transaction. Lessee and Lessor do each hereby agree to
indemnify, protect, defend and hold the other harmless from and against
liability for compensation or charges which may be claimed by any such unnamed
broker, finder or other similar party by reason of any dealings or actions of
the indemnifying Party, including any costs, expenses, and/or attorneys' fees
reasonably incurred with respect thereto.

16. Tenancy and Financial Statements.

      16.1 Tenancy Statement. Each Party (as "Responding Party") shall within
ten (10) days after written notice from the other Party (the "Requesting Party")
execute, acknowledge and deliver to the Requesting Party a statement in writing
in a form similar to the then most current "Tenancy Statement" form published by
the American Industrial Real Estate Association, plus such additional
information, confirmation and/or statements as may be reasonably requested by
the Requesting Party.

      16.2 Financial Statement. If Lessor desires to finance, refinance, or sell
the Premises or the Building, or any part thereof, Lessee and all Guarantors
shall deliver to any potential lender or purchaser designated by Lessor such
financial statements of Lessee and such Guarantors as may be reasonably required
by such lender or purchaser, including but not limited to Lessee's financial
statements for the past three (3) years. All such financial statements shall be
received by Lessor and such lender or purchaser in confidence and shall be used
only for the purposes herein set forth.

17. Lessor's Liability. The term "Lessor" as used herein shall mean the owner or
owners at the time in question of the fee title to the Premises. In the event of
a transfer of Lessor's title or interest in the Premises or in this Lease,
Lessor shall deliver to the transferee or assignee (in cash or by credit) any
unused Security Deposit held by Lessor at the time of such transfer or
assignment. Except as provided in Paragraph 15.3, upon such transfer or
assignment and delivery of the Security Deposit, as aforesaid, the prior Lessor
shall be relieved of all liability with respect to the obligations and/or
covenants under this Lease thereafter to be performed by the Lessor. Subject to
the foregoing, the obligations and/or covenants in this Lease to be performed by
the Lessor shall be binding only upon the Lessor as hereinabove defined.

      Severability. The invalidity of any provision of this Lease, as determined
by a court of competent jurisdiction, shall in no way affect the validity of any
other provision hereof.

19. Interest on Past-Due Obligations. Any monetary payment due Lessor hereunder,
other than late charges, not received by Lessor within ten (10) days following
the date on which it was due, shall bear interest from the date due at the prime
rate charged by the largest state chartered bank in the state in which the
Premises are located plus four percent (4%) per annum, but not exceeding the
maximum rate allowed by law, in addition to the potential late charge provided
for in Paragraph 13.4.

20. Time of Essence. Time is of the essence with respect to the performance of
all obligations to be performed or observed by the Parties under this Lease.

21. Rent Defined. All monetary obligations of Lessee to Lessor under the terms
of this Lease are deemed to be rent.

22. No Prior or other Agreements; Broker Disclaimer. This Lease contains all
agreements between the Parties with respect to any matter mentioned herein and
no other prior or contemporaneous agreement or understanding shall be effective.
[ILLEGIBLE]

23. Notices.

shall be in writing and may be delivered in person (by hand or by messenger or
courier service) or may be sent by regular, certified or registered mail or U.S.
Postal Service Express Mail, with postage prepaid, or by facsimile transmission
during normal business hours, and shall be deemed sufficiently given if served
in a manner specified in this Paragraph 23. The addresses noted adjacent to a
Party's signature on this Lease shall be that Party's address for delivery or
mailing of notice purposes. Either Party may by written notice to the other
specify a different address for notice purposes, except that upon Lessee's
taking possession of the Premises, the Premises shall constitute Lessee's
address for the purpose of mailing or delivering notices to Lessee. A copy of

transmission thereof, provided a copy is also delivered via delivery or mail. If
notice is received on a Saturday or a Sunday or a legal holiday, it shall be
deemed received on the next business day.

24. Waivers. No waiver by Lessor of the Default or Breach of any term, covenant
or condition hereof by Lessee, shall be deemed a waiver of any other term,
covenant or condition hereof, or of any subsequent Default or Breach by Lessee
of the same or any other term, covenant or condition hereof. Lessor's consent
to, or approval of, any such act shall not be deemed to render unnecessary the
obtaining of Lessor's consent to, or approval of, any subsequent or similar act
by [ILLEGIBLE] or be construed as the basis of an estoppel to enforce the
provision or provisions of this Lease requiring such consent. Regardless of
Lessor's knowledge of a Default or Breach at the time of accepting rent, the
acceptance of rent by Lessor shall not be a waiver of any Default or Breach by
Lessee of any provision hereof. Any payment given Lessor by Lessee may be
accepted by Lessor on account of moneys or damages due Lessor, notwithstanding
any qualifying statements or conditions made by Lessee in connection therewith,
which such statements and/or conditions shall be of no force or effect
whatsoever unless specifically agreed to in writing by Lessor at or before the
time of deposit of such payment.

25. Recording. Either Lessor or Lessee shall, upon request of the other,
execute, acknowledge and deliver to the other a short form memorandum of this
Lease for recording purposes. The Party requesting recordation shall be
responsible for payment of any fees or taxes applicable thereto.

26. No Right To Holdover. Lessee has no right to retain possession of the
Premises or any part thereof beyond the expiration or earlier termination of
this Lease. In the event that Lessee holds over in violation of this Paragraph
26 then the Base Rent payable from and after the time of the expiration or
earlier termination of this Lease shall be increased to two hundred percent
(200%) of the Base Rent applicable during the month immediately preceding such
expiration or earlier termination. Nothing contained herein shall be construed
as a consent by Lessor to any holding over by Lessee.

27. Cumulative Remedies. No remedy or election hereunder shall be deemed
exclusive but shall, wherever possible, be cumulative with all other remedies at
law or in equity.

28. Covenants and Conditions. All provisions of this Lease to be observed or
performed by Lessee are both covenants and conditions.

29. Binding Effect; Choice of Law. This Lease shall be binding upon the Parties,
their personal representatives, successors and assigns and be governed by the
laws of the State in which the Premises are located. Any litigation between the
Parties hereto concerning this Lease shall be initiated in the county in which
the Premises are located.

30. Subordination; Attornment; Non-Disturbance.

      30.1 Subordination. This Lease and any Option granted hereby shall be
subject and subordinate to any ground lease, mortgage. deed of trust, or other
hypothecation or security device (collectively, "Security Device"), now or
hereafter placed by Lessor upon the real property of which the Premises are a
part, to any and all advances made on the security thereof, and to all renewals,
modifications, consolidations, replacements and extensions thereof. Lessee
agrees that the Lenders holding any such Security Device shall have no duty
liability or obligation to perform any of the obligations of Lessor under this
Lease, but that in the event of Lessor's default with respect to any such
obligation, Lessee will give any Lender whose name and address have been
furnished Lessee in writing for such purpose notice of Lessor's default pursuant
to Paragraph 13.5. If any Lender shall elect to have this Lease and/or any
Option granted hereby superior to the lien of its Security Device and shall give
written notice thereof to Lessee, this Lease and such Options shall be deemed
prior to such Security Device, notwithstanding the relative dates of the
documentation or recordation thereof.

      30.2 Attornment. Subject to the non-disturbance provisions of Paragraph
30.3, Lessee agrees to attorn to a Lender or any other party who acquires
ownership of the Premises by reason of a foreclosure of a Security Device, and
that in the event of such foreclosure, such new owner shall not: (i) be liable
for any act or omission of any prior lessor or with respect to events occurring
prior to acquisition of ownership, (ii) be subject to any offsets or defenses
which Lessee might have against any prior lessor, or (iii) be bound by
prepayment of more than one month's rent.

      30.3 Non-Disturbance. With respect to Security Devices entered into by
Lessor after the execution of this lease, Lessee's subordination of this Lease
shall be subject to receiving assurance (a "non-disturbance agreement") from the
Lender that Lessee's possession and this Lease, including any options to extend
[ILLEGIBLE] hereof, will not be disturbed so long as Lessee is not in Breach
hereof and attorns to the record owner of the Premises.

      30.4 Self-Executing. The agreements contained in this Paragraph 30 shall
be effective without the execution of any further documents; provided, however,
that upon written request from Lessor or a Lender in connection with a sale,
financing or refinancing of Premises, Lessee and Lessor shall execute such
further writings as may be reasonably required to separately document any such
subordination or non-subordination, attornment and/or non-disturbance agreement
as is provided for herein.

31. Attorneys' Fees. If any Party or Broker brings an action or proceeding to
enforce the terms hereof or declare rights hereunder, the Prevailing Party (as
hereafter defined) in any such proceeding, action, or appeal thereon, shall be
entitled to reasonable attorneys' fees. Such fees may be awarded in the same
suit or recovered in a separate suit, whether or not such action or proceeding
is pursued to decision or judgment. The term "Prevailing Party" shall include,
without limitation, a Party or Broker who substantially obtains or defeats the
relief sought, as the case may be, whether by compromise, settlement, judgment,
or the abandonment by the other Party or Broker of its claim or defense. The
attorneys' fee award shall not be computed in accordance with any court fee
schedule, but shall be such as to fully reimburse all attorneys' fees reasonably
incurred. Lessor shall be entitled to attorneys' fees, costs and expenses
incurred in preparation and service of notices of Default and consultations in
connection therewith, whether or not a legal action is subsequently commenced in
connection with such Default or resulting Breach. Broker(s) shall be intended
third party beneficiaries of this Paragraph 31.

32. Lessor's Access; Showing Premises; Repairs. Lessor and Lessor's agents shall
have the right to enter the Premises at any time, in the case of an emergency,
and otherwise at reasonable times for the purpose of showing the same to
prospective purchasers, lenders, or lessees, and making such alterations,
repairs, improvements or additions to the Premises or to the Building, as Lessor
may reasonably deem necessary. Lessor may at any time place on or about the'
Premises or Building any ordinary "For Sale" signs and Lessor may at any time
during the last one hundred eighty (180) days of the term hereof place on or the
Premises any ordinary "For Lease" signs. All such activities of Lessor shall be
without abatement of rent or liability to Lessee.

33. Auctions. Lessee shall not conduct, nor permit to be conducted, either
voluntarily or involuntarily, any auction upon the Premises without first having
obtained Lessor's prior written consent. Notwithstanding anything to the
contrary in this Lease, Lessor shall not be obligated to exercise any standard
of reasonableness in determining whether to grant such consent.

34. Signs. Lessee shall not place any new sign upon the exterior of the Premises
or the Building, except that Lessee may, with Lessor's prior written consent,
install (but not on the roof) such signs as are reasonably required to advertise
Lessee's own business so long as such signs are in a location designated by
Lessor and comply with Applicable Requirements and the signage criteria
established for the Industrial Center by Lessor. Lessor hereby approves Lessee's
existing signs irrespective of the requirements of Exhibit D herein. The
[ILLEGIBLE] installation of any sign on the Premises by or for Lessee shall be
subject to the provisions of Paragraph 7 (Maintenance, Repairs, Utility
Installations, Trade Fixtures and Alterations). Unless otherwise expressly
agreed herein, Lessor reserves all rights to the use of the roof of the
Building, and the right to install advertising signs on the Building, including
the roof, which do not unreasonably interfere with the conduct of Lessee's
business; Lessor shall be entitled to all revenues from such advertising signs.

35. Termination; Merger. Unless specifically stated otherwise in writing by
Lessor, the voluntary or other surrender of this Lease by Lessee, the mutual
termination or cancellation hereof, or a termination hereof by Lessor for Breach
by Lessee, shall automatically terminate any sublease or lesser estate in the
Premises; provided, however, Lessor shall, in the event of any such surrender,
termination or cancellation, have the option to continue any one or all of any
existing subtenancies. Lessor's failure within ten (10) days following any such
event to make a written election to the contrary by written notice to the holder
of any such lesser interest, shall constitute Lessor's election to have such
event constitute the termination of such interest.

36. Consents.

            (a) Except for Paragraph 33 hereof (Auctions) or as otherwise
provided herein, wherever in this Lease the consent of a Party is required to an
[ILLEGIBLE] or for the other Party, such consent shall not be unreasonably
withheld or delayed. Lessor's actual reasonable costs and expenses (including
but not limited to architects', attorneys', engineers' and other consultants'
fees) incurred in the consideration of, or response to, a request by Lessee for
any Lessor consent pertaining to this Lease or the Premises, including but not
limited to consents to an assignment a subletting or the presence or use of a
Hazardous Substance, shall be paid by Lessee to Lessor upon receipt of an
invoice and supporting documentation therefor. In addition to the deposit
described In Paragraph 12.2(e), Lessor may, as a condition to considering any
such request by Lessee, require that Lessee deposit with Lessor an amount of
money (in addition to the Security Deposit held under Paragraph 5) reasonably
calculated by Lessor to represent the cost Lessor will incur in considering and
responding to Lessee's request. Any unused portion of said deposit shall be
refunded to Lessee without interest. Lessor's consent to any act, assignment of
this Lease or subletting of the Premises by Lessee shall not constitute an
acknowledgment that no Default or Breach by Lessee of this Lease exists, nor
shall such consent be deemed a waiver of any then existing Default or Breach,
except as may be otherwise specifically stated in writing by Lessor at the time
of such consent.

            (b) All conditions to Lessor's consent authorized by this Lease are
acknowledged by Lessee as being reasonable. The failure to specify herein any
particular condition to Lessor's consent shall not preclude the impositions by
Lessor at the time of consent of such further or other conditions as are then
reasonable with reference to the particular matter for which consent is being
given.

37. Guarantor.

    [ILLEGIBLE]

      Quiet Possession. Upon payment by Lessee of the rent for the Premises and
the performance of all of the covenants, conditions and provisions on Lessee's
part to be observed and performed under this Lease, Lessee shall have quiet
possession of the Premises for the entire term hereof subject to all of the
provisions of this Lease.

      39.2 Options Personal to Original Lessee. Each Option granted to Lessee in
this Lease is personal to the original Lessee named Paragraph 1.1[ILLEGIBLE],
and cannot be voluntarily or involuntarily assigned or exercised by any person
or entity other than said original Lessee while the original Lessee is in full
and actual possession of the Premises and without the intention of thereafter
assigning or subletting. The Options, if any, herein granted to Lessee are not
assignable, either as a part of an assignment of this Lease or separately or
apart therefrom, and no Option may be separated from this Lease in any manner,
by reservation or otherwise.

      39.3 Multiple Options. In the event that Lessee has any multiple Options
to extend or renew this Lease, a later option cannot be exercised unless the
prior Options to extend or renew this Lease have been validly exercised.

      39.4 Effect of Default on Options.

            (a) Lessee shall have no right to exercise an Option,
notwithstanding any provision in the grant of Option to the contrary: (i) during
the period commencing with the giving of any notice of Default under Paragraph
13.1 and continuing until the noticed Default is cured, or (ii) during the
period of time any monetary obligation due Lessor from Lessee is unpaid (without
regard to whether notice thereof is given Lessee), or (iii) during the time
Lessee is in Breach of this Lease, or (iv) in the event that Lessor has given to
Lessee three (3) or more notices of separate Defaults under Paragraph 13.1
during the twelve (12) month period immediately preceding the exercise of the
Option, whether or not the Defaults are cured.

            (b) The period of time within which an Option may be exercised shall
not be extended or enlarged by reason of Lessee's inability to exercise an
Option because of the provisions of Paragraph 39.4(a)

            (c) All rights of Lessee under the provisions of an Option shall
terminate and be of no further force or effect, notwithstanding Lessee's due and
timely exercise of the Option, if, after such exercise and during the term of
this Lease, (i) Lessee fails to pay to Lessor a monetary obligation of Lessee
for a period of thirty (30) days after such obligation becomes due (without any
necessity of Lessor to give notice thereof to Lessee), or (ii) Lessor gives to
Lessee three (3) or more notices of separate Defaults under Paragraph 13.1
during any twelve (12) month period, whether or not the Defaults are cured, or
(iii) if Lessee commits a Breach of this Lease.

observe all reasonable rules and regulations ("Rules and Regulations") which
Lessor may make from time to time for the management, safety, care, and

without the consent or joinder of Lessee, such easements, rights of way, utility
raceways, and dedications that Lessor deems necessary, and to cause the
recordation of parcel maps and restrictions, so long as such easements, rights
of way, utility raceways, dedications, maps and restrictions do not reasonably
interfere with the use of the Premises by Lessee. Lessee agrees to sign any
documents reasonably requested by Lessor to effectuate any such easement rights,
dedication, map or restrictions.

43. Performance Under Protest. If at any time a dispute shall arise as to any
amount or sum of money to be paid by one Party to the other under the provisions
hereof, the Party against whom the obligation to pay the money is asserted shall
have the right to make payment "under protest" and such payment shall not be
regarded as a voluntary payment and there shall survive the right on the part of
said Party to institute suit for recovery of such sum. If it shall be adjudged
that [ILLEGIBLE] was no legal obligation on the part of said Party to pay such
sum or any part thereof, said Party shall be entitled to recover such sum or so
much thereof as it [ILLEGIBLE] legally required to pay under the provisions of
this Lease.

44. Authority. If either Party hereto is a corporation, trust, or general or
limited partnership, each individual executing this Lease on behalf of such
entity represents and warrants that he or she is duly authorized to execute and
deliver this Lease on its behalf. if Lessee is a corporation, trust or
partnership, Lessee shall, within thirty (30) days after request by Lessor,
deliver to Lessor evidence satisfactory to Lessor of such authority.

45. Conflict. Any conflict between the printed provisions of this Lease and the
typewritten or handwritten provisions shall be controlled by the typewritten or
handwritten provisions.

46. Otter. Preparation of this Lease by either Lessor or Lessee or Lessor's

deemed an offer to lease. This Lease is not intended to be binding until
executed and delivered by all Parties hereto.

47. Amendments. This Lease may be modified only In writing, signed by the
parties in interest at the time of the modification. The Parties shall amend
this Lease from time to lime to reflect any adjustments that are made to the
Base Rent or other rent payable under this Lease. As long as they do not
materially change Lessee's obligations hereunder, Lessee agrees to make such
reasonable non-monetary modifications to this Lease as may be reasonably
required by an institutional insurance company or pension plan Lender in
connection with the obtaining of normal financing or refinancing of the property
of which the Premises are a part.

48. Multiple Parties. Except as otherwise expressly provided herein, if more
than one person or entity is named herein as either Lessor or Lessee, the
obligations of such multiple parties shall be the joint and several
responsibility of all persons or entities named herein as such Lessor or Lessee.

                           ADDENDA TO LEASE AGREEMENT

THIS ADDENDA is attached to and, by this reference, made a part of the Lease
Agreement dated April 3, 2000 made by and between ORANGEWOOD BUSINESS CENTER,
INC., a California corporation, as Lessor and Quality Systems, Inc. a California
corporation, as Lessee for the Premises located at 1701 E. Edinger Avenue, Bldg.
E, Units 5 - 8, Santa Ana, California.

                             49. COMPLIANCE WITH LAW
--------------------------------------------------------------------------------

49.1 Compliance with Law.

            Lessee, at Lessee's expense, shall comply with all laws, rules,
orders, ordinances, directions, regulations and requirements of federal, state,
county and municipal authorities pertaining to Lessee's use of the Premises and
with the recorded covenants, conditions and restriction, regardless of when they
become effective, including, with limitation, all applicable federal, state and
local laws, regulations or ordinances pertaining to air and water quality,
Hazardous Materials (as hereinafter defined), waste disposal, air emissions and
other environmental matters, all zoning and other land use matters, and utility
availability, and with any direction of any public officer or officers, pursuant
to law, which shall impose any duty upon Lessor or Lessee with respect to the
use or occupation of the Premises.

49.2 Use of Hazardous Materials.

            (1) Lessee shall (i) not cause or permit any Hazardous Material to
be brought upon, kept or used in or about the Premises or the Project by Lessee,
its agents, employees, contractors or invitees without the prior written consent
of Lessor, which Lessor shall not reasonable withhold as long as Lessee
demonstrates to Lessor's reasonable satisfaction that such Hazardous Material is
necessary or useful to Lessee's business and will be used, kept and stored in a
manner that complies with all laws regulating any such Hazardous Material so
brought upon or used or kept in or about the premises. If Lessee breaches the
obligations stated in the preceding sentence, or if the presence of Hazardous
Material on the Premises or the Project caused or permitted by Lessee results in
contamination of the Premises or the Project, or if contamination of the
Premises or the Project by Hazardous Material otherwise occurs for which Lessee
is legally liable to Lessor for damage resulting therefrom, then Lessee shall
indemnify, defend and hold Lessor harmless from any and all claims, judgments,
damages, penalties, fines, costs, liabilities or losses (including, without
limitation, diminution in value of the Premises or the Project, damages for the
loss or restriction on use of rentable or usable space or of any amenity of the
Premises or the Project, damages arising from any adverse impact on marketing of
space, and sums paid in settlement of claims, attorneys' fees, consultant fees
and expert fees) which arise during or after the Lease term as a result of such
contamination.

This indemnification of Lessor by Lessee includes, without limitation, costs
incurred in connection with any investigation of site conditions or any
clean-up, remedial, removal or restoration work required by any federal, state
or local governmental agency or political subdivision because of Hazardous
Material present in the soil or ground water on or under the Premises or the
Project. Without limiting the foregoing, if the presence of any Hazardous
Material on the Premises or the Project caused or permitted by Lessee results in
any contamination of the Premises or the Project, Lessee shall promptly take all
actions at its sole expense as are necessary to return the Premises and the
Project to the condition existing prior to the introduction of any such
Hazardous Material to the Premises or the Project; provided that Lessor's
approval of such actions shall first be obtained, which approval shall not be
unreasonably withheld so long as such actions would not potentially have any
material adverse long-term or short-term effect on the Premises or the Project.
The foregoing indemnity shall survive the expiration or earlier termination of
this Lease.

            (2) Definition of "Hazardous Material". As used herein, the term
"Hazardous Material" means any hazardous or toxic substance, material or waste,
including, but not limited to, those substances, materials, and wastes listed in
the United States Department of Transportation Hazardous Materials Table (49 CFR
172.101) or by the Environmental Protection Agency as hazardous substances (40
CFR Part 302) and amendments thereto, or such substances, materials and wastes
that are or become regulated under any applicable local, state or federal law.

            (3) Disclosure. At the commencement of this Lease, and on January 1
of each year thereafter (each such date being hereafter called "Disclosure
Dates"), including January 1 of the year after the termination of this Lease,
Lessee shall disclose to Lessor the names and amounts of all Hazardous
Materials, or any combination thereof, which were stored, used or disposed of on
or about the Premises, or which Lessee intends to store, use or dispose of on or
about the Premises.

            (4) Inspection. Lessor and its agents shall have the right, but not
the duty, to inspect the premises and the Project at any time to determine
whether Lessee is complying with the terms of this Lease. If Lessee is not in
compliance with this Lease, Lessor shall have the right to immediately enter
upon the Premises and the Project to remedy any contamination caused by Lessee's
