purposes and no other. The Premises shall not be used by Tenant for any illegal

         8.       Without limiting the other provisions of this Lease, the

this Lease: (a) any Rent is not paid within five (5) days after written notice

Building and shall not cure such failure within fifteen (15) days after written

Tenant under any section or chapter of the National Bankruptcy Act, as amended,
or any petition is filed against Tenant under said Act and is not discharged

virtue of this paragraph, Landlord shall have no obligation to notify Tenant of
any violations by Tenant of the terms of this Lease on more than two (2)
occasions during any twelve month period nor on more than five (5) occasions

                                      -7-
<PAGE>   8


                  Upon the occurrence of an event of default, in addition to and
not in limitation of any other right of remedy available to Landlord at law or
in equity, Landlord shall have the option of any time thereafter to:

                  (1)      Terminate this Lease (but Tenant shall nevertheless
remain liable for damages as hereinafter set forth), in which event Tenant shall
immediately surrender the Premises to Landlord but, if Tenant shall fail to so
do, Landlord may, without further notice and without prejudice to any other
remedy Landlord may have for possession or arrearages in Rent, enter upon the
Premises and expel or remove Tenant and Tenant's effects, by force if necessary,
without being liable to prosecution or any claim for damages therefor. Upon any
such termination Tenant shall pay to Landlord all Rent due and payable to the
date upon which this Lease shall have been terminated, and Landlord shall be
entitled to recover from Tenant, and Tenant shall pay to Landlord, on demand, as
and for liquidated and agreed final damages and not as penalty, a sum equal to
the amount by which the Base Rental and additional rent payable for the period
which otherwise would have constituted the unexpired portion of the Term
(conclusively presuming the additional rent to be the same as was payable for
the year immediately preceding such termination) exceeds the fair and reasonable
rental value of the Premises for the same period, both discounted at the rate of
seven percent per annum to present worth. In determining the fair and reasonable
rental value of the Premises, the rental realized by any relet, if such
reletting be accomplished by Landlord acting in good faith within a reasonable
time after termination of this Lease or after Landlord regains possession of the
Premises, shall be deemed prima facie to be the rental value, provided the new
lease is for a term of at least one (1) year and the new Tenant is a bona fide
third party. Furthermore, in determining the fair and reasonable rental value of
the Premises, all factors deemed relevant by Landlord should be considered as of
the time Landlord seeks to enforce such remedy, including, without limitation,
the length of time remaining in the Term, the market conditions in the general
area in which the Building is located, the likelihood of reletting the Premises
for a period of time equal to the remainder of the Term, the net effective
rental rates (taking into account all concessions) then being obtained for space
of similar type and size in similar buildings in the general area in which the
Building is located, vacancy levels in buildings in the general area in which
the Building is located, the anticipated duration of the period of time the
Premises will be unoccupied prior to reletting, the anticipated cost of
reletting, the then current levels of new construction that will be completed
during the remainder of the Term, and the degree to which such new construction
will likely affect vacancy and rental rates in buildings in the general area in
which the Building is located. Landlord and Tenant agree that it is difficult or
impossible to determine the actual damages Landlord will suffer from Tenant's
default hereunder and that the parties intend to provide for damages, not a
penalty, and that the agreed upon liquidated damages are fair and just and a
reasonable pre-estimate of such damages, all in accordance with O.C.G.A. Section
13-6-7.

                  (2)      Re-enter the Premises, without notice, either by
summary proceedings or by any other action or proceeding permitted by law
(without being liable for any claim for damages therefor), and repossess the
Premises and dispossess Tenant and any other persons from the Premises. Landlord
at any time thereafter may relet the Premises, or any part thereof, in the name
of Landlord or as agent for Tenant, for a term or terms which may, at Landlord's
option, be less than or exceed the period of the remainder of the Term, and at
such rent or rental or upon such other conditions, which may include concessions
as Landlord, in its sole reasonable discretion, shall determine. Landlord shall
receive the rents from such reletting and shall apply


                                      -8-
<PAGE>   9


the same, first, to pay such expenses as Landlord may have incurred in
connection with reentering, ejecting, removing, dispossessing, reletting,
altering, repairing, redecorating, subdividing, or otherwise preparing the
Premises for reletting, including without limitation brokerage and attorneys'
fees and expenses actually incurred; second, to the payment of any indebtedness
other than Rent charges and other sums due hereunder from Tenant to Landlord,
and the residue, if any, shall apply to the fulfillment of the terms, covenants
and conditions of Tenant hereunder, and Tenant hereby waives all claims to the
surplus, if any. Tenant shall be, and hereby agrees to be, liable for and to pay
Landlord any deficiency between the Rents, charges and other sums reserved
hereunder (conclusively presuming that additional rent is the same as payable
for the year immediately preceding such re-entry) and the net rentals, as
aforesaid, or relet, if any, for each month of the period which would otherwise
have constituted the balance of the Term. Tenant hereby agrees to pay such
deficiency in monthly installments on the date specified in this Lease for the
payment of Base Rental, and any suit or proceeding brought to collect a
deficiency for any month shall not prejudice or preclude in any way the right of
Landlord to collect a deficiency for any subsequent month by any similar suit or
proceeding. Landlord agrees to act in good faith to relet the Premises. Landlord
shall in no event be liable in any manner whatsoever for the failure to relet
the Premises or, in the event of such reletting, for failure to collect the
rents reserved thereunder. No such re-entry or taking possession of the Premises
by Landlord shall be construed as an election on its part to terminate this
Lease unless Landlord gives written notice to Tenant of such intention to so
terminate this Lease.

                  (3)      As agent for Tenant, Landlord, without thereby
waiving such default and without liability to Tenant in connection therewith,
may, but shall not be obligated to, cure any default of Tenant in the
performance by Tenant of any of the terms of this Lease on Tenant's part to be
performed. Landlord may enter the Premises at any time to cure any default
without any liability to Tenant. Tenant shall reimburse Landlord immediately
upon demand for any expenses which Landlord may incur in effecting compliance
with this Lease on behalf of Tenant.

                  (4)      [omitted]

         9.       If Tenant shall not remove all its effects from said Premises
at the expiration or termination of this Lease, Landlord may, at its option,
remove all or part of said effects in any manner that Landlord shall choose and
store the same without liability to Tenant for loss thereof, and Tenant shall
reimburse Landlord on demand for all reasonable expenses incurred in such
removal and also storage of said effects. Notwithstanding any changes to
paragraph 9, Landlord shall retain its statutory rights provided under Georgia
law.

POSSESSION

         10.      If this Lease is executed before the Premises become ready for
occupancy and Landlord cannot deliver possession of the Premises by the time the
Term is fixed herein to begin, this Lease shall not be void or voidable (except
as hereinbelow provided) and Tenant waives any claim for damages due to such
delay. In the event Landlord fails to deliver the Premises to Tenant for
occupancy before ninety (90) days after the Commencement Date due to reasons
other than the fault of Tenant or circumstances beyond the reasonable control of
Landlord, then


                                      -9-
<PAGE>   10

Tenant shall have the right and option to terminate this Lease as Tenant's sole
and exclusive remedy against Landlord.

SERVICES

         11.      Provided Tenant has not abandoned the Premises and there
exists no event of default on behalf of Tenant, Landlord shall furnish to the
Premises the following services in the following amounts:

                  (a)      Janitorial services on Monday through Friday, but
excepting New Year's Day, Memorial Day, July 4th, Labor Day, Thanksgiving Day
and the Friday following Thanksgiving Day, and Christmas Day (the "Holidays");

                  (b)      Electricity in the Premises on a level suitable as of
the date of this Lease for normal office use, including usual and normal small
office machines and similar equipment using 110 volt current, and lighting of
the Premises to building standard light levels produced by building standard
fluorescent lighting fixtures (Tenant being obligated to pay for replacement of
all light bulbs excluding fluorescent tubes); which shall be the responsibility
of Landlord.

                  (c)      Seasonal air conditioning and heating on Monday
through Friday, excluding the Holidays, from 8:00 A.M. to 6:00 P.M. and
Saturdays from 8:00 A.M. to 12:00 P.M.

                  Landlord reserves the right to prohibit installation within
the Premises of equipment using electricity in amounts greater than the amounts
provided, including, but not limited to, non-standard lighting, electric
heaters, air conditioners, data processing equipment, computer and allied
equipment components and duplicating equipment, telephone and telecommunication
equipment, stoves, microwaves, refrigerators and vending machines.

                  In no event shall Tenant's use of electric current exceed the
capacity of existing feeders to the Building, risers, wiring installations or
other facilities which serve utilities to the Premises. Landlord further
reserves the right to prohibit the installation of any additional equipment
(including, without limitation, the equipment described above, air cleaners and
exchangers, water filtration systems and devices, sinks, and water heaters)
unless and until arrangements are made by Tenant, acceptable to Landlord, to
install such additional equipment and to install supplementary air conditioning
equipment (including any submetering of the same) on the Premises at Tenant's
cost and expense to support such additional equipment and the use thereof. Any
cost of operation and maintenance of such additional equipment or supplementary
air conditioning services incurred by Landlord shall be paid by Tenant to
Landlord as additional rent on the monthly rental payment date set forth in this
Lease for Base Rental. Tenant shall be solely responsible for all damages to
Tenant, its employees, guest, invitees, officers, and agents and to the Premises
and to the Building and other tenants of the Building which result, directly or
indirectly, from the installation or use of the additional equipment abovesaid.
Should Tenant desire heating or air conditioning at times when such services are
not furnished by Landlord under the terms of this Lease, Landlord will furnish
such services as requested by Tenant upon reasonable advance written notice from
Tenant, in a format designated by Landlord, and Tenant shall pay to Landlord the
then currently established charges for such services as additional rent


                                      -10-
<PAGE>   11


on demand. Landlord shall not be liable for any damages directly or indirectly
resulting from the installation, use, or interruption of use of utilities or the
furnishing of services referred to in this paragraph where such interruption
results from circumstances beyond Landlord's reasonable control or from
interruptions made necessary by repairs and maintenance being undertaken by
Landlord. Notwithstanding any other term hereof to the contrary, Landlord shall
have no obligation to service, maintain, or repair any such additional
equipment. Tenant agrees to service, maintain, and repair all such additional
equipment.

SUBLETTING AND ASSIGNMENTS

         12.      Tenant shall not voluntarily, involuntarily, or by operation
of law assign, transfer, hypothecate, or otherwise encumber this Lease or any
interest herein and shall not sublet or permit the use by others of the Premises
or any part thereof without first obtaining in each instance Landlord's prior,
written consent, which consent Landlord shall be entitled to withhold in its
sole discretion. Landlord's consent to one assignment, sublease, transfer, or
hypothecation shall not be deemed consent to any other or further assignment,
sublease, transfer, or hypothecation. Any such assignment, sublease, transfer,
or hypothecation without Landlord's prior, written consent shall be void and
shall constitute an immediate event of default under this Lease. No acceptance
by Landlord of any Rent or any other sum of money from any assignee, subtenant
or other category of transferee shall release Tenant from any of its obligations
hereunder or be deemed to constitute Landlord's consent to any assignment,
sublease, transfer, or hypothecation. In the event Tenant shall desire to assign
this Lease or sublet the Premises or any part thereof, if Tenant is not then in
default under this Lease, Tenant shall give Landlord written notice at least
forty-five (45) days in advance of the date on which Tenant desires to make such
assignment or sublease, which notice shall specify: (a) the name and business of
the proposed assignee or subtenant, (b) reasonably detailed character and
financial references for the proposed assignee or subtenant (including a recent
certified financial statement), (c) the amount and location of space in the
Premises affected, (d) the proposed effective date and duration of the
subletting or assignment, (e) the proposed rental and all other consideration to
be paid to Tenant by such subtenant or assignee, and (f) the extent to which
parking utilization may be adversely affected by such assignee or subtenant and
their employees, guests, and invitees. Landlord shall then have a period of
thirty (30) days following receipt of such notice within which to notify Tenant
in writing that Landlord elects, at its option: (1) to terminate this Lease as
to the space so affected as of the date so specified by Tenant, in which event
Tenant will on the proposed commencement date in the sublease, surrender to
Landlord possession of the affected space and thereafter be relieved of all
further obligations to pay Rent hereunder as to such space; or (2) to permit
Tenant to assign or sublet such space, in which event any rent payable by
subtenant to Tenant in excess of the rental rate of this Lease, net of costs
associated with subleasing the premises including but not limited to free rent
and commission, shall be deemed additional rent owed by Tenant to Landlord under
this Lease in the same manner that Tenant pays Base Rental hereunder and in
addition thereto (similarly, any sums payable by any proposed assignee to Tenant
in consideration of an assignment of Tenant's interest in this Lease which are
properly allocable to such assignment [as determined by Landlord in its sole
discretion based upon reasonable attribution methods] shall be payable by Tenant
to Landlord as additional rent and in consideration of Landlord's consent to
such assignment); or (3) to withhold consent to Tenant's assignment or sublease
of such space and to continue this Lease in full force and effect as to the
entire Premises. If Landlord shall elect to terminate this Lease as aforesaid,
Tenant shall notify


                                      -11-
<PAGE>   12


Landlord in writing within ten (10) days thereafter of Tenant's intention to
either refrain from such assignment, subletting, or transfer or to accept the
termination of this Lease. If Tenant advises Landlord it intends to refrain from
such assignment, subletting, or transfer, then Landlord's right to terminate
this Lease as aforesaid shall be null and void in such instance. If Tenant fails
to so notify Landlord within said 10-day period, then Tenant will be deemed to
have accepted such termination of this Lease; and, upon any such termination,
Landlord shall have the right to enter into a direct Lease with Tenant's
proposed assignee, subtenant, or other transferee. In no event whatsoever, shall
(x) Tenant sublet, assign, or otherwise endeavor to transfer any interest of
Tenant in this Lease to any other existing tenant of space in Piedmont Center or
to any person or party or affiliate thereof which has been a tenant of space in
Piedmont Center within the preceding six (6) months, (y) Tenant communicate, in
writing, in any way the availability of all or any part of the Premises at a
rental rate which is less than the rate for which Landlord is then offering any
other space in the Building or the Complex, or (z) any advertisement or other
publication for subletting or assignment state the name (as distinguished from
the address) of the Building. Notwithstanding the giving by Landlord of its
consent to any assignment or sublease with respect to the Premises, no assignee
or sublessee may exercise any expansion option, right of first refusal option,
renewal, or extension option under this Lease except in accordance with a
separate written agreement entered into directly between such assignee or
sublessee and Landlord. Notwithstanding the giving by Landlord of its consent to
any assignment or sublease or any language contained in any such assignment of
sublease to the contrary, Tenant shall not be relieved of any of Tenant's
obligations or covenants under this Lease, and Tenant shall remain fully liable
hereunder. Tenant agrees to pay to Landlord, on demand, reasonable costs
(including, without limitation, attorneys' fees and expenses) incurred by
Landlord in connection with any request by Tenant for Landlord to consent to any
assignment or subletting by Tenant not to exceed $700.00 per request. Any
transfer after the date hereof, whether to one or more persons or entities and
whether at one or more different times, of a controlling interest in Tenant
(regardless whether Tenant is a corporation, partnership, or other entity),
whether voluntarily, by operation of law, or otherwise, shall be deemed an
assignment of this Lease within the meaning of this Paragraph 12.
Notwithstanding any other term or provision hereof, if Landlord consents to any
assignment or subletting of this Lease, Tenant shall have the sole obligation to
remove or cause to be removed any Hazardous Substances (as defined below)
required to be removed because of the assignee's or subtenant's renovations or
improvements of intended use of the Premises; and Landlord shall have no
responsibility therefor.

DESTRUCTION OR DAMAGE

         13.      (a)      In the event the Premises or the Building are damaged
by fire or other cause and in Landlord's reasonable estimation such damage can
be materially restored within one hundred fifty (150) days, Landlord shall
forthwith repair the same and this Lease shall remain in full force and effect,
except that Tenant shall be entitled to a proportionate abatement in Rent from
the date of such damage. Such abatement of Rent shall be made pro rata in
accordance with the extent to which the damage and the making of such repairs
shall interfere with the use and occupancy by Tenant of the Premises from time
to time. Within forty-five (45) days from the date of such damage, Landlord
shall notify Tenant, in writing, of Landlord's reasonable estimation of the
length of time within which material restoration can be made, and Landlord's
determination shall be binding on Tenant. For purposes of this Lease, the
Building or Premises shall be deemed "materially restored" if they are in such
condition as would not


                                      -12-
<PAGE>   13


prevent or materially interfere with Tenant's use of the Premises for the
purpose for which it was being used immediately before such damage.

                  (b)      If such repairs cannot, in Landlord's reasonable
estimation, be made within one hundred fifty (150) days, Landlord and Tenant
shall each have the option of giving the other, at any time within sixty (60)
days after such damage, notice terminating this Lease as of the date of such
damage. In the event of the giving of such notice, this Lease shall expire and
all interest of Tenant in the Premises shall terminate as of the date of such
damage as if such date had been originally fixed in this Lease for the
expiration of the Term. In the event that neither Landlord nor Tenant exercises
its option to terminate this Lease, then Landlord shall repair or restore such
damage, this Lease continuing in full force and effect, and the Rent hereunder
shall be proportionately abated as provided in Paragraph 13(a).

                  (c)      Landlord shall not be required to repair or replace
any damage or loss by or from fire or other cause to any panelings, decorations,
partitions, additions, railings, ceilings, floor coverings, office fixtures or
any other property or improvements installed on the Premises or belonging to
Tenant but in such instance, Landlord shall be obligated to repair and restore
all other portions of the Premises, including all walls, wall coverings,
carpets, ceilings, electrical, heating, ventilating, and air conditioning
equipment and other utility services, connections and wiring previously located
in the Premises. Any insurance which may be carried by Landlord or Tenant
against loss or damage to the Building or Premises shall be for the sole benefit
of the party carrying such insurance and under its sole control.

                  (d)      In the event that Landlord should fail to complete
such repairs and material restoration within sixty (60) days after the date
estimated by Landlord therefor as extended by this Paragraph 13, Tenant may, at
its option and as it sole remedy, terminate this Lease by delivering written
notice to Landlord, within fifteen (15) days after the expiration of said period
of time whereupon the Lease shall end on the date of such notice or such later
date fixed in such notice as if the date of such notice was the date originally
fixed in this Lease for the expiration of the Term; provided, however, that if
construction is delayed because of changes, deletions or additions in
construction requested by Tenant, strikes, lockouts, casualties, Acts of God,
war, material or labor shortages, government regulation or control or other
causes beyond the reasonable control of Landlord, the period for restoration,
repair or rebuilding shall be extended for the amount of time Landlord is so
delayed.

                  (e)      Notwithstanding anything to the contrary contained in
this Paragraph 13: (i) Landlord shall not have any obligation whatsoever to
repair, reconstruct, or restore the Premises when the damages resulting from any
casualty covered by the provisions of this Paragraph 13 occur during the last
twelve (12) months of the Term or any extension thereof, or if the damages are
not covered by Landlord's insurance, but if Landlord determines not to repair
such damages Landlord shall notify Tenant and if such damages shall render any
material portion of the Premises untenantable, Tenant shall have the right to
terminate this Lease by notice to Landlord within fifteen (15) days after
receipt of Landlord's notice, and (ii) in the event the holder of any
indebtedness secured by a mortgage, deed of trust, security deed or other
security instrument covering the Premises or Building requires that any
insurance proceeds be applied to such indebtedness, then Landlord shall have the
right to terminate this Lease by delivering written notice of termination to
Tenant within fifteen (15) days after such requirement is made


                                      -13-
<PAGE>   14


by any such holder, whereupon this Lease shall end on the date of such damage as
if the date of such damage were the date originally fixed in this Lease for the
expiration of the Term.

                  (f)      In the event of any damage or destruction to the
Building or Premises by any peril covered by the provisions of this Paragraph
15, it shall be Tenant's responsibility to properly secure the Premises and upon
notice from Landlord to remove forthwith, at its sole cost and expense, such
portion of all of the property belonging to Tenant or its licensees from such
portion or all of the Building or Premises as Landlord shall request.

CONDEMNATIONS

         14.      If the whole or any material part of the Premises shall be
taken or condemned by any competent authority, then the Term shall cease and
terminate from the date when the possession of the part so taken shall be
required for such use or purpose, and the entire amount of the condemnation
award shall be paid to Landlord (excepting only any portion of such award
designated for moving expenses). If the whole or any material part of the
Building shall be taken or condemned by any competent authority (regardless of
whether or not any portion of the Premises shall be so taken or condemned),
Landlord shall have the right to terminate this Lease upon notice to Tenant.

ALTERATION AND IMPROVEMENTS

         15.      Tenant will make no alterations in, or additions to, the
Premises without first obtaining Landlord's written consent. All such
alterations shall be made in accordance with all governmental laws, ordinances,
rules and regulations. All erections, additions, fixtures, and improvements,
(excluding, without limitation, telephone and telecommunication equipment and
cabling) (collectively, the "alterations") whether temporary or permanent in
character (except only movable office furniture and equipment of Tenant), made
in or upon the Premises, either by Tenant or Landlord, shall be Landlord's
property, and shall remain upon said Premises at the termination of the Term by
lapse of time or otherwise, without compensation to Tenant. At Landlord's
election, Tenant shall, at its sole expense, cause to be removed from the
Premises at the end of the Term all such alterations, provided Landlord notifies
Tenant of its duty to remove such alterations at the time of Landlord's consent.
As a condition to granting consent to the making of such alteration or
additions, Landlord may impose such requirements as Landlord may in its sole
reasonable discretion deem reasonable or necessary including, by way of
illustration and not limitation, requirements as to the manner in which or time
at which such work is performed, the design of such alterations, the quality of
materials and workmanship utilized in making such alterations, the selection of
the contractor who shall perform the work required to complete such alterations,
and the providing for all lien waivers and evidence of insurance with respect to
each contractor employed by Tenant. If, in connection with the initial build-out
of the Premises for Tenant or in connection with any subsequent alterations or
additions to the Premises, Tenant uses a contractor other than Landlord or its
affiliate, or an affiliate of PC Associates, then Landlord shall be paid a
supervisory fee equal to five percent (5%) of the total of the construction
contract with Tenant's third-party contractor or contractors. Said fee shall be
due and payable as and when payments are made under Tenant's construction
contract or contracts. Tenant shall pay, in addition to any sums due pursuant to
Paragraph 3 herein, any increase in real estate taxes attributable to any such
alteration for so long, during the Term, as


                                      -14-
<PAGE>   15


such increase is ascertainable; at Landlord's election said sums shall be paid
in the same way as sums due under Paragraph 3(b) herein.

ATTORNEY'S FEES; LATE PAYMENTS

         16.      In any action involving a dispute arising from the obligations
of the parties hereto the prevailing party shall be entitled to recover
reasonable actual attorneys' fees from the other party. In connection with any
installment of Rent not paid when due, Landlord shall be entitled to charge
Tenant either (a) interest on the Rent due at the rate of the lesser of (i)
fifteen percent (15%) per annum or (ii) the maximum rate allowed by law, after
as well as before judgment, from the due date until paid, or (b) a per diem fee
of $25.00 for each day after the due date until paid. Tenant agrees that the
actual loss to Landlord because of Tenant's failure to pay when due is not
readily calculable and that the foregoing is intended to provide liquidated
damages, not a penalty, and that the foregoing is a reasonable pre-estimate of
such loss.

RULES AND REGULATIONS

         17.      The rules and regulations attached to this Lease as Exhibit
"B" shall be and are hereby made an integral part of this Lease. Tenant, its
contractors, servants, and agents, will perform and abide by said rules and
regulations and any amendments or additions to said rules and regulations as may
be made from time to time by Landlord, upon notice to Tenant, for the safety,
care, cleanliness, and preservation of good order in the Building. Landlord
shall not be responsible to Tenant for the non-performance by any other tenant
or occupant of the Complex of any such rules and regulations.

NO ESTATE

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

HOLDING OVER

         19.      If Tenant remains in possession of the Premises after
expiration or termination of the Term, with Landlord's acquiescence and without
any distinct agreement of the parties, then Tenant by virtue of this paragraph
shall become a tenant from month-to-month at a monthly base rent, payable in
advance, in an amount equal to 150% of the amount of Base Rent payable for the
last month of the Term and otherwise subject to all of the conditions and
covenants of this Lease as though this Lease had originally been a
month-to-month tenancy. In no event shall there be a renewal of this Lease by
operation of law, and any such month-to-month tenancy may be terminated by
either Landlord or Tenant by giving thirty (30) days written notice to the
other. Notwithstanding the foregoing, if Tenant shall remain in possession of
the Premises as a holdover tenant without the acquiescence of Landlord or
otherwise in violation of the terms and provisions of this Lease, in addition to
any other rights and remedies available to Landlord, Landlord shall have the
immediate right to re-enter and take possession of the Premises.


                                      -15-
<PAGE>   16


SURRENDER OF PREMISES

         20.      At the expiration or termination of this Lease, Tenant shall
surrender the Premises (and all keys and/or access control keys and devices to
the Premises) to Landlord in good condition, natural wear and tear only
excepted. Any property, including, without limitation, cable communication
equipment, owned or leased by Tenant left upon the Premises at the termination
of this Lease shall be deemed abandoned by Tenant, and Landlord may thereafter
use or dispose of such property as Landlord sees fit without obligation to
Tenant. Tenant shall reimburse Landlord on demand for Landlord's costs and
expenses in removing, storing and disposing of such property, and Tenant shall
further indemnify and hold Landlord free and harmless from any liability, claim
or expense suffered or incurred by Landlord in connection with the removal or
disposal of such property. This Paragraph 20 shall expressly survive the
termination or expiration of this Lease, but only if such property remains on
the Premises for five (5) business days after notice is given by Landlord that
the property is subject to removal and loss. Notice to be given at the addresses
specified in paragraph 21 of the Lease.

         21.      Notices required or permitted hereunder or given to Tenant

                  Either party may, by written notice to the other, specify a
different address for notice purposes, except that Landlord may in any event use
the Premises as proper and sufficient for service of dispossessory or disraint
proceedings and notice of an event of default.

PARTIES

         22.      "Landlord" as used in this Lease shall include Landlord, its
representatives, assigns and successors-in-title to the Premises. It is
understood and agreed that the term "Landlord", as used in this Lease, means
only the owner (or the tenant under a superior lease) from time to time of the
Building so that in the event of any sale, Landlord as transferor shall be
relieved of all covenants and obligation of Landlord hereunder, and Tenant shall
attorn to any successor Landlord hereunder. "Tenant" shall include Tenant, its
representatives and, if this Lease shall be validly assigned or sublet, shall
include also Tenant's assignees or subtenants, as to the Premises covered by
such assignment or sublease. "Landlord" and "Tenant" include male and female,
singular and plural, corporation, partnership, other entity, or individual, as
may fit the particular parties.

CHANGE OF PREMISES

         23.      [OMITTED]

SECURITY DEPOSIT

         24.      Tenant shall deposit the amount of $17,326.83 (the "Security
Deposit") with Landlord upon the execution of this Lease. The acceptance by
Landlord of the Security Deposit paid by Tenant shall not render this Lease
effective unless and until Landlord shall have executed and delivered to Tenant
a fully executed copy of this Lease. Said sum shall be held by Landlord as
security for the faithful performance by Tenant of all the terms, covenants and
conditions of this Lease to be kept and performed by Tenant and not as an
advance rental deposit or as a measure of Landlord's damage in case of Tenant's
default. If Tenant defaults with respect to any provision of this Lease,
Landlord may use any part of the Security Deposit for the payment of any rent or
any other sum in default, or for the payment of any amount which Landlord may
spend or become obligated to spend by reason of Tenant's default, or to
compensate Landlord for any other loss or damage which Landlord may suffer by
reason of Tenant's default. If any portion is so used, Tenant shall within five
(5) days after written demand therefor, deposit with Landlord an amount
sufficient to restore the Security Deposit to its original amount and Tenant's
failure to do so shall be a material breach of this Lease. Except to such
extent, if any, as shall be required by law, Landlord shall not be required to
keep the Security Deposit separate from its general funds, and Tenant shall not
be entitled to interest on such deposit. If Tenant shall fully and faithfully
perform every provision of this Lease to be


                                      -17-
<PAGE>   18


performed by it, the Security Deposit or any balance thereof shall be returned
to Tenant at such time after termination of this Lease when Landlord shall have
determined that all of Tenant's obligations under this Lease have been
fulfilled.

SUBORDINATION

         25.      This Lease and all rights of Tenant hereunder are and shall be
inferior and subordinate to any mortgage, deed to secure debt, deed of trust or
other security instrument in the nature thereof which may now or hereafter
affect Landlord's interest in the Premises or Building and to any modifications,
renewals, consolidations, extensions, or replacements of any such security
instrument; provided, however, that Landlord, mortgagee, trustee or holder of
any such mortgage, deed to secure debt, deed of trust or other security
instrument in the nature thereof may, by notice to Tenant, elect to have
Tenant's interest in this Lease be superior to any such instrument, in which
case this Lease shall be deemed superior, whether this Lease was executed before
or after said instrument. This paragraph shall be self-operative, and no further
instrument of subordination shall be required by the holder of any such security
instrument. Tenant shall, however, execute, acknowledge, and deliver to Landlord
or the holder of any such security instrument, upon demand and without expense,
any and all instruments that may be requested by Landlord for the purpose of
subordinating (or making superior) this Lease and the rights of Tenant hereunder
to the rights and interests of the holder of such security instrument and for
any and all purposes reasonably related thereto. In the event the holder of any
such security instrument or purchaser at foreclosure shall hereafter succeed to
the rights of Landlord under this Lease, whether by foreclosure or other means,
Tenant shall attorn to and recognize same as the successor Landlord under this
Lease and shall promptly execute and deliver any instrument that may be
necessary to evidence such attornment.

ESTOPPEL CERTIFICATES

         26.      Tenant shall at any time and from time to time, upon not less
than ten (10) days prior, written notice from Landlord, execute, acknowledge and

EXCULPATION

         27.      Notwithstanding anything to the contrary contained herein,
express or implied, Landlord's obligations and liability to Tenant with respect
to this Lease shall be limited solely to Landlord's interest in the Building
(subject to the rights of any holders of security interests in the Building),
and neither Landlord nor any of its trustees, board of directors and officers,
as the case may be, its investment manager, the general partners thereof, or any

employees or agents of Landlord or the investment manager shall have any
personal liability whatsoever with respect to this Lease or Landlord's
obligations hereunder.

QUIET POSSESSION

         28.      Upon Tenant's paying the Rent hereunder and observing and
performing all of the covenants, conditions and provisions on Tenant's part to

Premises for the Term, subject to all of the terms and provisions of this Lease.
Notwithstanding the foregoing, Tenant agrees that any towing of any vehicles
which are owned by Tenant or its employees and which are illegally or improperly
parked shall not constitute a violation of Tenant's quiet enjoyment; and Tenant
hereby releases Landlord from all claims Tenant, its employees, guests, and
invitees may have against Landlord as a result of any proper exercise by
Landlord of its rights aforesaid. Such towing shall not, in any event,
constitute a breach of this Paragraph 28.

HAZARDOUS SUBSTANCES

         29.      Tenant hereby represents and warrants to Landlord that Tenant
has not brought or permitted to be brought, and covenants and agrees with
Landlord that Tenant will not bring or permit to be brought on the Premises or
any portion thereof any substances or materials (hereinafter collectively called
"Hazardous Substances") except those substances common used in business offices,
the generation, handling, manufacturing, treatment, storage, use,
transportation, or discharge of which are regulated by any state, federal, or
local law, rule, regulation, or notice or may result in a diminution or
impairment of air or water quality. Tenant hereby indemnifies and agrees to hold
Landlord harmless from and against (a) all costs, fees, and expenses (including,
without limitation, attorneys', engineers' and consultants' fees and costs
actually incurred) in connection with the presence of any Hazardous Substances
on the Premises first introduced by Tenant onto the Premises after the
Commencement Date; (b) all claims, liabilities, expenses, or damages imposed on
Landlord or incurred by Landlord by any person (including, without limitation,
any employee, invitee, or guest of Tenant), entity, or governmental body
whatsoever and arising out of any claims, action, administrative proceedings,
judgments, damages, penalties, fines, and costs, including, without limitation,
attorneys', engineers, and consultants' fees and costs, costs of investigation,
and settlement, that arise directly or indirectly from or in connection with the
presence, release, or suspected release of any Hazardous Substances at, or, or
about the Premises as a result of any action or omission of Tenant; (c) any
diminution in the value of the Building arising directly or indirectly from or
in connection with the presence, release, or suspected release of any Hazardous
Substances at, on, or near the Premises as a result of any action or omission of
Tenant; and (d) all loss of rental resulting from the presence, release, or
suspected release of any Hazardous Substances at, in, or near the Premises or
at, in, or near the Complex as a result of any action or omission by Tenant.
Tenant agrees to notify Landlord (i) of any investigation of the Premises for
Hazardous Substances by any consultant engaged by Tenant or others on Tenant's
behalf or any governmental or quasi-governmental agency, department, commission,
or committee and (ii) of any suit or threatened suit against Tenant with regard
to the discharge, release, or possible discharge or release of Hazardous
Substances at, near, or about the Premises. Further, Tenant agrees to provide
Landlord with true, correct, and complete copies of all test results conducted
by or at the request of Tenant with respect to the possible presence of
Hazardous Substances at,

                                      -19-
<PAGE>   20

near, or about the Premises. Any permitted alterations or permitted improvements
to the Premises made by Tenant shall be made and maintained in compliance with
all environmental, health, and safety laws applicable to the Premises. In
addition to its rights under Paragraph 7 above, Landlord shall have the right,
but not the obligation or duty, to enter or to have its engineer and consultants
enter the Premises at reasonable hours to test for the presence of Hazardous
Substances. Such testing shall be at Landlord's expenses; provided, however, if
such testing reveals the presence of Hazardous Substances above any permissible
levels or quantities, Tenant shall promptly reimburse Landlord for the costs of
such tests and shall promptly remove or cause to be removed any excessive
Hazardous Substances. The indemnifications contained in this Paragraph 29 shall
inure to the benefit of Landlord, its successors, successors-in-title, assigns,
mortgagees, lenders, partners, joint venturers, officers, directors, members,
employees, and agents. The terms and provisions of this Paragraph 29 shall
survive the expiration or earlier termination of this Lease.

NON-LIABILITY AND INDEMNIFICATION

         30.      None of the Landlord Entities (as defined in Paragraph 32)
shall be liable and Tenant hereby waives all claims against them for any damage
to any property or any injury to any person in or about the Premises or the
Building by or from any cause whatsoever (including, without limitation, rain or
water leakage of any character from the roof, windows, walls, basement, pipes,
plumbing works or appliances, the Building not being in good condition or
repair, gas fire, oil, electricity or theft), except to the extent caused by or
arising from the gross negligence or willful misconduct of Landlord or its
agents, employees or contractors. Tenant shall protect, indemnify and hold the
Landlord Entities harmless from and against any and all loss, claims, liability
or costs (including court costs and attorney's fees) incurred by reason of (a)
any damage to any property (including but not limited to property of any
Landlord Entity) or any injury (including but not limited to death) to any
person occurring in, on or about the Premises or the Complex to the extent that
such injury or damage shall be caused by or arise from any actual or alleged
act, neglect, fault, or omission by or of Tenant, its agents, servants,
employees, invitees, or visitors to meet any standards imposed by any duty with
respect to the injury or damage; (b) the conduct or management of any work or
thing whatsoever done by Tenant in or about the Premises or from transactions of
Tenant concerning the Premises; (c) Tenant's failure to comply with any and all
governmental laws, ordinances and regulations applicable to the condition or use
of the Premises or its occupancy; or (d) any breach or default on the part of
Tenant in the performance of any covenant or agreement on the part of Tenant to
be performed pursuant to this Lease, including, but not limited to, Paragraph
29. The provisions of this Paragraph shall survive the termination or expiration
of this Lease with respect to any claims or liability accruing prior to such
termination or expiration.

ENTIRE AGREEMENT, ETC.

         31.      This Lease contains the entire agreement of the parties, and
no representation or agreements, oral or otherwise, between the parties not
embodied herein shall be of any force or effect. No failure of Landlord to
exercise any power given Landlord hereunder, or to insist upon strict compliance
by Tenant of any obligation hereunder, and no custom or practice of the parties
at variance with the terms hereof, shall constitute a waiver of Landlord's right
to demand exact compliance with the terms hereof. Submission of this Lease shall
not be deemed to be a

                                      -20-
<PAGE>   21

reservation of the Premises. Landlord shall not be bound by this Lease until it
has received a copy of this Lease duly executed by Tenant and has delivered to
Tenant a copy of this Lease duly executed by Landlord, and until such delivery
Landlord reserves the right to exhibit and lease the Premises to other
prospective tenants. Notwithstanding anything contained in this Lease to the
contrary, Landlord may withhold delivery of possession of the Premises from
Tenant until such time as Tenant has paid to Landlord any security deposit
required by Paragraph 24, the first month's rent as set forth in Paragraph 3 and
any sum owed pursuant to this Lease.

                  This Lease may be executed in one or more counterparts, each
of which shall be deemed an original, and all of which shall constitute one and
the same instrument. This Lease shall be governed by the laws of the State of
Georgia. Tenant shall not record this Lease or any memorandum hereof. The terms
of this Lease are to be given their meaning under Georgia law without any
presumption or construction for or against any party over the other as to the
author of said terms, because all parties hereto jointly claim said terms as
their own for purposes of this Lease.

DEFINED TERMS AND HEADINGS

         32.      The Paragraph headings shown in this Lease are for convenience
of reference and shall in no way define, increase, limit or describe the scope

Landlord shall apply to and inure to the benefit of all of the following
"Landlord Entities", being Landlord, Landlord's investment manager, and the
trustees, boards of directors, officers, general partners, beneficiaries,
stockholders, employees and agents of each of them. Any option granted to
Landlord shall also include or be exercisable by Landlord's trustee,
beneficiary, agents and employees, as the case may be. In any case where this
Lease is signed by more than one person or entity, the obligations under this
Lease shall be joint and several. The terms "Tenant" and "Landlord" or any
pronoun used in place thereof shall indicate and include the masculine or
feminine, the singular or plural number, individuals, firms or corporations, and
each of their respective successors, executors, administrators and permitted
assigns, according to the context hereof. The term "rentable area" shall mean
the rentable area of the Premises or the Building as calculated by the Landlord
on the basis of the plans and specifications of the Building including a
proportionate share of any common areas. Tenant hereby accepts and agrees to be
bound by the figures for the rentable space footage of the Premises and Tenant's
Share as defined in Paragraph 3.

TIME OF ESSENCE

         33.      Time is of the essence of this Lease.

BROKERS

         34.      Tenant represents and warrants to Landlord that, except for
William Leonard & Co. ("Broker"), Tenant has not engaged or had any
conversations or negotiations with any broker, finder or other third party
concerning the leasing of the Premises to Tenant who would be entitled to any
commission or fee based on the execution of this Lease. Tenant hereby further
represents and warrants to Landlord that Tenant is not receiving and is not
entitled to receive any rebate, payment or other remuneration, either directly
or indirectly, from Broker, and that it is

<PAGE>   22

not otherwise sharing in or entitled to share in any commission or fee paid to
Broker by Landlord or any other party in connection with the execution of this
Lease, either directly or indirectly. Tenant hereby indemnifies Landlord against
and from any claims for any brokerage commissions (except those payable to
Broker, all of which are payable by Landlord pursuant to a separate agreement)
and all costs, expenses and liabilities in connection therewith, including,
without limitation, reasonable attorneys' fees and expenses, for any breach of
the foregoing. The foregoing indemnification shall survive the termination or
expiration of this Lease.

TENANT'S BANKRUPTCY OR INSOLVENCY

         35.      If at any time and for so long as Tenant shall be subjected to
the provisions of the United States Bankruptcy Code or other law of the United
States or any state thereof for the protection of debtors as in effect at such
time (each a "Debtor's Law"): Tenant, Tenant as debtor-in-possession, and any
trustee or receiver of Tenant's assets (each a "Tenant's Representative") shall
have no greater right to assume or assign this Lease or any interest in this
Lease, or to sublease any of the Premises than accorded to Tenant in Paragraph
12 hereof, except to the extent Landlord shall be required to permit such
assumption, assignment or sublease by the provisions of such Debtor's Law.
Without limitation of the generality of the foregoing, any right of any Tenant's
Representative to assume or assign this Lease or to sublease any of the Premises
shall be subject to the conditions that:

                  (a)      Such Debtor's Law shall provide to Tenant's
Representative a right of assumption of this Lease which Tenant's Representative
shall have timely exercised and Tenant's Representative shall have fully cured
any default of Tenant under this Lease.

                  (b)      Tenant's Representative or the proposed assignee, as
the case shall be, shall have deposited with Landlord as security for the timely
payment of Rent an amount equal to the larger of: (a) three months' Base Rental
and other monetary charges accruing under this Lease; and (b) any sum specified
in Paragraph 24 hereof; and shall have provided Landlord with adequate other
assurance of the future performance of the obligations of Tenant under this
Lease. Without limitation, such assurances shall include, at least, in the case
of assumption of this Lease, demonstration to the satisfaction of Landlord that
Tenant's Representative has and will continue to have sufficient unencumbered
assets after the payment of all secured obligations and administrative expenses
to assure Landlord that Tenant's Representative will have sufficient funds to
fulfill the obligations of Tenant under this Lease; and, in the case of
assignment, submission of current financial statements of the proposed assignee,
audited by an independent certified public accountant reasonably acceptable to
Landlord and showing a net worth and working capital in amounts determined by
Landlord to be sufficient to assure the future performance by such assignee of
all of the Tenant's obligations under this Lease.

                  (c)      The assumption or any contemplated assignment of this
Lease or subleasing any part of the Premises, as shall be the case, will not
breach any provision in any other lease, mortgage, financing agreement or other
agreement by which Landlord is bound.

                  (d)      Landlord shall have or would have had absent the
Debtor's Law, no right under Paragraph 12 hereof to refuse consent to the
proposed assignment or sublease by reason of

                                      -22-

reputation or interest of the Building or the tenants of the Building may be
denied access to the Building or may be ejected from the Building.

<CAPTION>
                           <S>                  <C>

</TABLE>

         The above said base rental shall be subject to adjustment as provided
for in the Lease.

         3.       Beginning on January 1, 2001, Tenant's base rental figures
shown in paragraph 2 herein shall be adjusted annually by two and one-quarter
percent (2.25%). The adjusted figures shall establish the new base rental
figure.

         4.       Tenant shall provide to Landlord either a Letter of Credit
(LOC) or Certificate of Deposit (CD) issued by a bank with a branch in Metro
Atlanta equal to the sum of $100,000.00. This sum shall be increased by fifty
percent (50%) of any increase over the $10.00 per rentable square foot Tenant
Improvement Allowance provided for in the Lease. Tenant shall provide such LOC
or CD within thirty (30) days of execution of the Lease or prior to the
commencement of construction of the improvements in the Premises, whichever is
sooner. Should Tenant fail to provide an acceptable LOC or CD to Landlord within
said time frame given herein, this Lease shall become null and void, and Tenant
shall reimburse Landlord for any costs it has expended on construction drawings
and associated costs for the Premises. Said LOC or CD shall be payable to
Landlord in the event Tenant defaults under the terms and conditions of this
Lease. Said LOC or CD shall have an initial term of not less than one (1) year
and shall be renewed for two (2) additional twelve (12) month periods not less

required. Notwithstanding anything to the contrary in Paragraph 8 of the Lease,
should Tenant fail to provide Landlord with proof of said renewal of the LOC or
CD thirty days prior to the expiration of the LOC or CD, an event of default
shall have immediately occurred and Landlord shall be entitled to call the LOC

accompanied by an affidavit stating that an event of default has occurred on the
part of the Tenant and remains uncured, provided a cure period is applicable.
Provided no event of default has occurred and remains uncured after the
appropriate cure period during the first three (3) years of Lease Term, the
requirement of this LOC or CD shall be waived. Should Tenant become a publicly
traded company, provided Tenant is not in default under the terms of this Lease,
then ninety (90) days after the date upon which the Tenant became a publicly
traded company, the LOC or CD shall be waived. Similarly, should Tenant receive
another round of capital funding of at least $5,000,000.00, the LOC or CD shall
be waived ninety (90) days after the date the abovesaid sum is deposited in
Tenant's account.

         5.       Provided Tenant is not in default under the terms and
conditions of this Lease and has not sublet its entire Premises, Tenant shall
have the option to lease approximately 4,265 rentable square feet as shown
outlined in green on Exhibit "A" attached hereto on August 1, 2000 provided
Tenant has given Landlord written notice of its intent to exercise said option
not later than March 1, 2000. Should Tenant exercise said option the rental rate
shall be that rate Tenant is paying at that time. Further, Landlord shall
provide a prorated amount of the original Tenant Improvement Allowance set forth
in Exhibit "D". The proration shall be based on the total months of occupancy
for the option space.

on approximately 13,640 rentable square feet or any portion thereof on the sixth
floor of Building Seven, should the tenant who presently occupies said space not
renew its lease or should such space become available for lease. Tenant shall
have five (5) days to exercise its right in writing after notification from
Landlord that Landlord has a bona fide third party offer for said space. Absence
of notice by Tenant shall be deemed to be a waiver of the rights provided
herein. The terms and conditions for such space shall be the same as those
agreed upon between the Landlord and the third party for the space.

         7.       Landlord hereby provides Tenant with a Second Right of Refusal
on approximately 16,000 rentable square feet on the fourth floor of Building
Seven, subject to existing tenants' rights. Tenant shall have five (5) days to
exercise its right in writing after notification from Landlord that Landlord has
a bona fide third party offer for said space. Absence of notice by Tenant shall
be deemed to be a waiver of the rights provided herein. The terms and conditions
for such space shall be the same as those agreed upon between the Landlord and
the third party for the space.

         8.       Seasonal air conditioning and heating on Saturdays shall be

                                    EXHIBIT D

                             LEASEHOLD IMPROVEMENTS


         This Exhibit "D" is a part of the Lease between PIEDMONT OFFICE CENTER,
INC., a Delaware corporation, as Landlord, and NOVIENT, INC., a Georgia
corporation, as Tenant, for Suite 500, Seven Piedmont Center.

         1.       Tenant accepts the Premises in its present "as-is" condition.
Landlord will contribute up to $10.00 per rentable square foot towards leasehold
improvements, including cable and telephone work to the Premises.

         2.       Landlord's Work. Landlord shall provide design and
construction of the work to the Premises described on Schedule 1 attached hereto
("Landlord's Work"). Tenant may not use or occupy the Premises with a number of
personnel greater than is contemplated in the approved space plans. As further
provided herein, Tenant shall be responsible for the incremental cost of
Landlord's Work in excess of the Maximum TI Allowance (as defined below).

         3.       Cost and Allowance.

                  (a)      This Lease and the rental rates provided for herein
are premises on a total cost of Landlord's Work not to exceed $212,850.00
($10.00 per RSF) (the "Maximum TI Allowance"). The "cost of Landlord's Work"
includes, without limitation:

                           (i)      All costs and expenses  actually incurred by
Landlord pertaining to Landlord's Work, including, but not limited to, costs
charged by contractors, subcontractors and general and other conditions costs
and expenses in connection with preparation of the Premises for occupancy;

                           (ii)     All costs and expenses of preparation of the
plans for such construction, and site inspection and contract administration by
Landlord's consulting architects and/or engineers;

                           (iii)    All costs of permits, licenses and other
approvals required for the performance of Landlord's Work; and

                           (iv)     A construction management fee to Landlord,
or Landlord's agent, of five percent (5%) of the total of all such costs under
the foregoing subsections (i), (ii) and (iii).

                  (b)      If the total cost of Landlord's Work exceeds the
Maximum TI Allowance, the entire amount of such excess (the "Excess TI Cost")
shall be borne by Tenant and shall be paid to Landlord by Tenant upon demand as
additional rent under the Lease. Prior to commencing any of Landlord's Work,
Landlord shall submit to Tenant for Tenant's reasonable approval a written
estimate of the cost of Landlord's Work (the "Estimate"). If Tenant fails to
either approve or reasonably object to the Estimate within five (5) business
days after Tenant's receipt thereof, then Tenant shall be deemed to have
approved the Estimate. Landlord will require Tenant to deposit with Landlord
within five (5) days after Landlord's written request

<PAGE>   36

therefore the amount of the agreed-upon Estimate which exceeds the Maximum TI
Allowance (the "Excess TI Deposit"). The Excess TI Deposit shall be held as
security for the payment of and shall be credited, without interest, against the
sums payable by Tenant under this Lease. Landlord shall not be required to
commence the Landlord's Work until payment of the Excess TI Deposit is received.
Any delay in completing Landlord's Work by the Commencement Date that results
from a delay by Tenant to deposit the Excess TI Deposit with Landlord within
said five (5) day period shall be deemed a delay caused by Tenant under Section
2(c) of the Lease.

                  (c)      Notwithstanding anything to the contrary contained
herein, Tenant may notify Landlord prior to the Commencement Date of Tenant's
election to reimburse Landlord for the Excess TI Cost by payments to Landlord of
monthly additional rent (in the same manner and on the same terms as Base
Rental) in an amount that would fully amortize the Excess TI Cost with interest
at twelve percent (12%) over the initial Term of the Lease. Notwithstanding
anything to the contrary contained herein, the maximum amount of the Excess TI
Cost which Tenant may elect to amortize hereunder is $42,570.00 ($2.00 per
rentable square foot), and any amount of the Excess TI Cost which exceeds said
maximum amount shall be paid by Tenant to Landlord upon demand.

         4.       Miscellaneous.

                  (a)      Except as set forth in this Exhibit D, Landlord has
no other agreement with Tenant and has no obligation to do any work with respect
to the Premises. Any other work in the Premises which may be permitted by
Landlord pursuant to the terms and conditions of the Lease shall be done at
Tenant's sole cost and expense and in accordance with the terms and provisions
of the Lease.

                  (b)      All rights and remedies of Landlord herein created or
otherwise existing at law or equity are cumulative, and the exercise of one or
more such rights or remedies shall not be deemed to exclude or waive the right
to the exercise of any other rights or remedies. All such rights and remedies
may be exercised and enforced concurrently and whenever and as often as deemed
desirable.

                  (c)      This Exhibit D shall not be deemed applicable to any
additional space added to the original Premises at any time or from time to
time, whether by any options under the Lease or otherwise, or to any portion of
the original Premises or any additions thereto in the event of a renewal or
extension of the original term of the Lease, whether by any options under the
Lease or otherwise.

         5.       Recapture of Concessions. Tenant understands and agrees that
in entering into this Lease, Landlord is relying upon receipt of all the Base
Rental to become due with respect to all of the Premises over the full Term of
this Lease for amortization, including an interest factor of ten percent (10%)
per annum (the "Interest Rate") of the Concession Amount. For purposes hereof,
the "Concession Amount" shall be defined as the aggregate of the Maximum TI
Allowance, any amount of the Excess TI Cost which Tenant has elected to amortize
hereunder and the brokers' commissions becoming due by reason of this Lease.

<PAGE>   37

                  Accordingly, Tenant agrees that if this Lease or Tenant's
right to possession of the Premises leased hereunder shall be terminated as of
any date ("Termination Date") prior to the expiration of the full Term hereof by
any reason other than a Landlord default, there shall be due and owing to
Landlord as of the day prior to the Termination Date, as rent in addition to all
other amounts owed by Tenant as of such Termination Date, the amount
("Unamortized Amount") of the Concession Amount determined as set forth below,
provided, however, that in the event that the Unamortized Amount is recovered by
Landlord pursuant to any other provision of this Lease, Landlord agrees that it
shall not attempt to recover the Unamortized Amount pursuant to this paragraph.

                  For the purposes hereof, the Unamortized Amount shall be
determined in the same manner as the remaining principal balance of a mortgage
with the Interest Rate payable in level payments over the same length of time as
the current Term of the Lease would be determined; to illustrate, according to a
standard mortgage amortization table, the principal amount outstanding (i.e. the
unamortized amount) at the end of the fifth year of a loan of $1,000.00 payable
in level payments with interest at 8% over ten years will be $598.00 assuming
all payments to that point are made as due.
