         NOW, THEREFORE, in consideration of the foregoing and the mutual
premises and covenants contained herein and in the Lease, and for other good and
valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, Landlord and Tenant hereby agree as follows:

         1. Defined Terms. All terms used herein and denoted by their initial
capitalization shall have the meanings set forth in the Lease unless set forth
herein to the contrary.

         2. Extension of Term. Effective immediately, Landlord and Tenant hereby
extend the term of the Lease for the Premises for an additional forty-five (45)
month period, commencing on October 1, 2003 (the "Extended Term Commencement
Date"), and ending on June 30, 2007, unless sooner terminated in accordance with
the terms of the Lease. That period commencing on the Extended Term Commencement
Date and continuing to and through June 30, 2007, is herein sometimes referred
to as the "Extended Term". Tenant leases the Premises during the Extended Term
on the same terms and conditions presently set forth in the Lease, except as
otherwise set forth herein to the contrary; provided, however, Tenant shall
receive no concessions or allowances on account of extending the term of the
Lease.

         3. Base Rental.

         (a) From and after the Extended Term Commencement Date to and through
the expiration of the Extended Term, Tenant shall pay to Landlord base rental
("Base Rental") for the 8125 Space, on the first day of each month without
demand, counter-claim or set-off in accordance with the following schedule:

Dates                   PSF      Annual Rental     Monthly Rental
-----                   ---      -------------     --------------
10/01/03 - 12/31/03     $0.00    $0.00             $0.00
01/01/04 - 09/30/05     $2.65    $214,321.44       $17,860.12
10/01/05 - 09/30/06     $2.70    $218,365.20       $18,197.10
10/01/06 - 06/30/07     $2.75    $222,408.96       $18,534.08

         (b) From and after the Extended Term Commencement Date to and through
December 31, 2004, Tenant shall pay to Landlord Base Rental for the 8055 Space,
as if the 8055 Space only contained 5,000 rentable square feet of space.
Thereafter, Tenant shall pay to Landlord Base Rental for the 8055 Space based
upon the actual square footage of the 8055 Space which is 17,200 rentable square
feet of space. Tenant shall pay such Base Rent for the 8055 Space on the first
day of each month without demand, counter-claim or set-off in accordance with
the following schedule:

Dates                   PSF      Annual Rental     Monthly Rental
-----                   ---      -------------     --------------
10/01/03 - 12/31/04     $2.00    $10,000.00        $   833.33

         4. Operating Expenses.

         (a) Notwithstanding anything to the contrary in the Lease, as amended
hereby, effective as of the Extended Term Commencement, Section 3(e) of the
Lease shall be of no further force and effect. Commencing on the Extended Term
Commencement Date, Tenant shall pay Landlord in accordance with the terms and
conditions set forth herein, throughout the Extended Term, as additional rental,
Tenant's pro rata share of the amount by which the amount of operating expenses
(as defined in Section 3(f) of the Lease) with respect to any given calendar
year exceed $0.15 per square foot. Prior to or promptly after the beginning of
each calendar year during the Extended Term, Landlord shall estimate the total
amount of operating expenses to be paid by Tenant during such calendar year, and
Tenant shall pay to Landlord one-twelfth (1/12) of such sum on the first day of
each calendar month during each such calendar year, or part thereof, during the
Extended Term. Within a reasonable time after the end of each calendar year,
Landlord shall submit to Tenant a statement of the actual amount of operating
expenses for such calendar year, and the actual amount owed by Tenant, and
within thirty (30) days after receipt of such statement, Tenant shall pay any
deficiency between the actual amount owed and the estimates paid during such
calendar year, or in the event of overpayment, Landlord shall either, at
Landlord's option, credit the amount of such overpayment toward the next
installment of operating expenses and/or Base Rental owed by Tenant or refund
such overpayment to Tenant; provided, however, any overage due Tenant during the
last year of the Extended Term shall be refunded to Tenant. The obligations in


                                       20
<PAGE>

the immediately preceding sentence shall survive the expiration or any earlier
termination of the Lease. If Tenant does not notify Landlord of any objection to
Landlord's year-end statement within thirty (30) days of Landlord's delivery
thereof, Tenant shall be deemed to have accepted such statement as true and
correct and shall be deemed to have waived any right to dispute the excess
operating expenses due pursuant to that statement. If the Extended Term
Commencement Date shall fall on other than the first day of the calendar year,
and/or if the last day of the Extended Term shall fall on other than the last
day of the calendar year, Tenant's proportionate share of the operating expenses
for such calendar year shall be apportioned prorata. The obligation to pay such
additional rental amounts shall survive the termination of the Lease, as amended
hereby. For all purposes of the Lease, as amended hereby, the term "Pro Rata
Share" shall mean (i) with respect to the 8125 Space, the ratio of the total
floor area of the 8125 Space to the total floor area of the 8125 Building or the
Project, as applicable (and consistent with historic practice of allocating
operating expenses under the Lease), and (ii) with respect to the 8055 Space,
the ratio of 17,200 square feet to the total area of the 8055 Building or the
Project, as applicable (and consistent with historic practice of allocating
operating expenses under the Lease).

         (b) For purposes of calculating Tenant's share of Landlord's operating
expenses pursuant to Section 3 of the Lease, as amended hereby, Landlord and
Tenant hereby agree that, commencing with the second full calendar year of the
Extended Term, Landlord's operating expenses less Uncontrollable Costs shall be
deemed not to increase by more than five percent (5.0%) (such percentage cap is
herein referred to as the "Operating Expense Cap") from one calendar year to the
next calendar year, regardless of any actual increases in operating expenses;
provided, however, in the event that in any calendar year any such increase in
operating expenses is in fact greater than the Operating Expense Cap (any such
increase in excess of the Operating Expense Cap being hereinafter collectively
referred to as the "Carryover Percentage"), Landlord shall have the right to add
all of the Carryover Percentage (or such portion thereof as will not produce a
total increase in operating expenses in excess of the Operating Expense Cap) to
the increases in operating expenses occurring over any of the following years of
the Extended Term in which such increases in operating expenses are less than
the Operating Expense Cap, on a cumulative basis until all such Carryover
Percentages have been used to increase operating expenses for purposes of
calculating Tenant's share of Landlord's operating expenses payable pursuant to
Section 3 of the Lease, as amended hereby. The foregoing provisions of this
Section notwithstanding, real estate taxes and assessments, all utility costs
and expenses, including, without limitation, those for electricity and other
fuels and forms of power or energy, water charges, sewer and waste disposal, all
costs to comply with legal requirements, and the cost of all casualty, liability
and other insurance applicable to the Building and/or the Project and Landlord's
personal property used in connection with the Building and/or the Project (all
of the foregoing are herein collectively referred to as "Uncontrollable Costs")
shall not be subject to any limitation or cap, and, accordingly, the total
dollar increase in operating expenses, and Tenant's share of Landlord's
operating expenses payable pursuant to Section 3 of the Lease, for any and each
calendar year during the Extended Term shall be calculated without any
limitation or cap on Uncontrollable Costs.

         5. Condition of the Premises/Use of Premises.

         (a) Notwithstanding anything to the contrary contained or implied in
this Fourth Amendment, Tenant agrees that it will accept possession of the
Premises during the Extended Term in an "as is, where is" condition, and that no
representations, warranties, or inducements, with respect to any condition of
the Premises have been made by Landlord, or its designated representatives, to
Tenant, or its designated representatives. In furtherance of the foregoing,
Tenant hereby acknowledges that no promises to decorate, alter, repair or
improve the Premises either before or after the execution of this Fourth
Amendment have been made to Tenant, or its designated representatives, by
Landlord, or its designated representatives.

                                       21
<PAGE>

         (b) Notwithstanding anything to the contrary contained in the Lease, as
amended hereby, Tenant shall use the 8055 Space for dry storage purposes only
and for no other use. Tenant's use of the Premises shall be in compliance with
any and all applicable laws, codes, rules, ordinances and regulations from any
and all applicable governing authorities.

         6. HVAC Maintenance. Notwithstanding anything to the contrary contained
in the Lease or this Fourth Amendment, in the event the heating, ventilation and
air conditioning ("HVAC") system serving the 8125 Space requires repair or
replacement during the Extended Term, Tenant shall bear any and all costs
associated with such maintenance and repair of the HVAC system up to a maximum
amount of $1,000.00 per Occurrence (as defined below), and Landlord shall pay
any and all costs associated with such maintenance and repair of the HVAC system
in excess of $1,000.00 per Occurrence ("Excess HVAC Costs"). Notwithstanding the
foregoing, Landlord shall have no obligation to pay for any repairs or
maintenance of the HVAC system serving the 8125 Space in the event Tenant fails
to properly maintain the HVAC system pursuant to a standard HVAC maintenance
agreement with a licensed HVAC contractor, as required by the Lease. Further,
Landlord makes no warranty and shall have no obligation to make any repairs or
perform any maintenance on the HVAC system necessitated by the negligence or
intentional misconduct of Tenant, or its officers, employees, agents,
contractors, sublessees or invitees. "Occurrence" shall mean any one problem
associated with the HVAC system in any sixty (60) consecutive day period during
the Extended Term regardless of the number of visits by the HVAC
contractor(s)/vender(s).

         7. Termination Right for 8125 Space. Tenant shall have the one-time
right to terminate the Lease, as amended hereby, as the same applies to the 8125
Space, effective as of the last day of the twenty-seventh (27th) full calendar
month following the Extended Term Commencement Date (the "Effective Termination
Date for the 8125 Space"), subject to the following terms and conditions:

         (a) Landlord shall have received from Tenant written notice delivered
in accordance with the notice provisions of the Lease that Tenant has
irrevocably exercised its right to terminate the Lease, as the same applies to
the 8125 Space, at least one hundred eighty (180) days prior to the Effective
Termination Date for the 8125 Space, time being of the essence.

         (b) In consideration of Landlord granting to Tenant the right to
terminate the Lease, as amended hereby, as the same applies to the 8125 space,
as described above, Tenant shall deliver to Landlord contemporaneously with
Tenant's notice described in subsection (a) above, a certified check in an
amount equal to Forty-One Thousand and 00/100ths Dollars ($41,000.00).

         (c) On or before the Effective Termination Date for the 8125 Space, as
set forth above, Tenant shall have removed from the 8125 Space all its personal
property which the Lease allows Tenant to remove, Tenant shall have removed all
of its signage, and Tenant shall have peacefully surrendered the 8125 Space and
the keys thereto to Landlord in the same condition as on the original
commencement date of the Lease, only normal wear and tear excepted.

         (d) The Lease, as amended hereby, shall be in full force and effect as
the same pertains to the 8125 Space on the date of the exercise of such
termination option and the Effective Termination Date for the 8125 Space, and,
further, there shall exist no bona fide material monetary default on the part of
Tenant under the Lease, as amended hereby, beyond any applicable notice and cure
period, on the date of the exercise of such termination option and on the
Effective Termination Date for the 8125 Space.

         (e) If Tenant fails to exercise such termination option as provided in
and in strict accordance with the terms of this Section 7, or if the conditions
in subsections (a) through and including (d) above are not entirely satisfied,
Tenant's option to terminate the Lease, as amended hereby, as the same applies
to the 8125 Space, shall automatically terminate and be of no further force or
effect, or if exercised, shall be void.

         8. Tenant's Termination Right for 8055 Space. Tenant shall have the
on-going right to terminate the Lease, as amended hereby, as the same applies to
the 8055 Space, effective as of December 31st of each calendar year during the
Extended Term commencing with December 31, 2004 (the specific December 31st on
which the Lease as the same applies to the 8055 Space terminates shall be
referred to as the "Effective Termination Date for the 8055 Space"), subject to
the following terms and conditions:

                                       22
<PAGE>

         (a) Landlord shall have received from Tenant written notice delivered
in accordance with the notice provisions of the Lease that Tenant has
irrevocably exercised its right to terminate the Lease, as the same applies to
the 8055 Space, on or before the November 1st directly preceding the Effective
Termination Date for the 8055 Space, time being of the essence.

         (b) On or before the Effective Termination Date for the 8055 Space, as
set forth above, Tenant shall have removed from the 8055 Space all its personal
property which the Lease allows Tenant to remove, Tenant shall have removed all
of its signage, and Tenant shall have peacefully surrendered the 8055 Space and
the keys thereto to Landlord in the same condition as on the date Tenant first
occupied the 8055 Space, only normal wear and tear excepted.

         (c) The Lease, as amended hereby, shall be in full force and effect as
the same pertains to the 8055 Space on the date of the exercise of such
termination option and the Effective Termination Date for the 8055 Space, and,
further, there shall exist no bona fide material monetary default on the part of
Tenant under the Lease, as amended hereby, beyond any applicable notice and cure
period, on the date of the exercise of such termination option and on the
Effective Termination Date for the 8055 Space.

         (d) If Tenant fails to exercise such termination option as provided in
and in strict accordance with the terms of this Section 8, or if the conditions
in subsections (a) through and including (c) above are not entirely satisfied,
Tenant's option to terminate the Lease, as amended hereby, as the same applies
to the 8055 Space for a specific December 31st shall automatically terminate and
be of no further force or effect, or if exercised, shall be void.

         9. Landlord's Termination Right/Tenant's Right of First Refusal.
Notwithstanding anything to the contrary contained in the Lease, as amended
hereby, the parties acknowledge and agree that the 8055 Space contains a total
of approximately 17,200 rentable square feet; provided, however, during the
first fifteen (15) months of the Extended Term, Tenant is paying Base Rental on
the 8055 Space as if the 8055 Space contained 5,000 rentable square feet.
Notwithstanding anything to the contrary contained herein and in consideration
of the reduced Base Rental for the 8055 Space and Tenant's termination right as
set forth in Section 8 above, Tenant acknowledges that Landlord shall have the
right to terminate the Lease as the same applies to the 8055 Space in accordance
with the terms and conditions set forth herein.

         (a) During the Extended Term, Landlord shall have the right to market
the 8055 Space to third parties upon terms and conditions acceptable to Landlord
in Landlord's sole discretion. Additionally, Tenant acknowledges that, in
accordance with the Third Amendment, Landlord has the right, upon reasonable
prior oral or written notice to Tenant, to exhibit the 8055 Space to prospective
tenants and that during the duration of the Extended Term Landlord has the
right, but not the obligation, to market the 8055 Space to such prospects.

         (b) In the event Landlord obtains a written offer from a prospective
tenant to lease all or any portion of the 8055 Space and Landlord desires to
accept such offer, then Landlord shall promptly submit to Tenant in writing all
of the terms and conditions of such proposed offer to lease (hereinafter
referred to as the "Offer") and Tenant shall have the right and option to lease
the 8055 Space upon the same monetary terms and conditions, including any offer
of free rent and leasehold improvement allowances, and term length as embodied
in the copy of such Offer submitted to Tenant by Landlord, but otherwise upon
the same terms and conditions as the Lease, as amended hereby. Notwithstanding
the foregoing, in the event Tenant accepts the terms of the Offer, Tenant's
termination right for the 8055 Space as set forth in Section 8 above, shall
automatically terminate and be of no further force and effect.

         (c) If Tenant shall elect to exercise its right to lease the 8055
Space, written notice of such election shall be given to Landlord within ten
(10) days from the time that Tenant first received a copy of the Offer from
Landlord (hereinafter referred to as the "Offer Period"). If Tenant does not
accept the terms of the Offer within the Offer Period or Tenant waives its
rights under the Offer (no notice is deemed to be a waiver of such right), then
Landlord, at Landlord's option shall have the right to terminate the Lease, as
amended hereby, as the same applies to the 8055 Space, upon thirty (30) days
advance written notice to Tenant.

                                       23
<PAGE>

         (d) In the event the Lease, as amended hereby, is terminated as the
same pertains to the 8055 Space, in accordance with the terms of this Section 9,
then on or before the actual termination date, Tenant shall remove from the 8055
Space all its personal property which the Lease allows Tenant to remove, Tenant
shall remove all of its signage, and Tenant shall peacefully surrender the 8055
Space and the keys thereto to Landlord in the same condition as on the date
Tenant first occupied the 8055 Space, only normal wear and tear excepted.

         (e) In the event Tenant accepts the terms of the Offer, Landlord and
Tenant shall enter into a written agreement modifying and supplementing the
Lease, as amended hereby, and specifying the appropriate terms and provisions
relating to the terms and conditions of the Offer, including, without
limitation, increasing, adjusting or augmenting rent.

         10. Guaranty Release. As a material inducement for Tenant to enter into
this Fourth Amendment, effective as of the Effective Date, Landlord releases
Guarantor from any and all claims first arising under the Lease from and after
the Effective Date. Guarantor shall be a third party beneficiary, entitled to
enforce this provision.

         11. Brokers. Tenant represents and warrants to Landlord that other than
Carter & Associates, LLC ("Carter"), no broker, agent, commission salesperson,
or other person, including, without limitation, New Southern Commercial
Properties and/or New South Commercial Properties, Inc., has represented Tenant
in the negotiations for and procurement of this Fourth Amendment and the
extension of the term and that, other than Carter, no commissions, fees or
compensation of any kind are due and payable in connection herewith to any
broker, agent, commission salesperson or other person as a result of any act or
agreement of Tenant, including without limitation New Southern Commercial
Properties and/or New South Commercial Properties, Inc. Tenant agrees that, if
any broker other than Carter makes a claim for a commission based upon the
actions of Tenant, Tenant shall indemnify, defend and hold Landlord harmless
from any such claim. Landlord shall pay Carter a commission pursuant to a
separate written agreement. The parties hereto do hereby acknowledge and agree
that Grubb & Ellis Company has acted as agent for Landlord and not for Tenant in
this transaction and shall be paid a commission by Landlord in connection with
this transaction pursuant to the terms of a separate written commission
agreement. Landlord agrees that, if any other broker other than Grubb & Ellis
Company makes a claim for a commission based upon the actions of Landlord,
Landlord shall indemnify, defend and hold Tenant harmless from any such claim.

         12. Notice Address. From and after the date of this Fourth Amendment,
Tenant's notice address as set forth in Section 33 of the Lease is hereby
deleted and replaced with the following:

             Sparks Exhibits & Environments, Inc.
             8125 Troon Circle
             Suite D
             Austell, GA 30168
             Attn: Timothy Oughton

         13. Miscellaneous. This Fourth Amendment shall be governed by and
construed in accordance with the laws of the State of Georgia, and shall be
binding upon and inure to the benefit of the parties hereto and their respective
successors, successors-in-title, representatives and permitted assigns. In the
event of any inconsistency or conflict between the terms of this Fourth
Amendment and of the Lease, the terms of this Fourth Amendment shall control.
Time is of the essence of all of the terms of this Fourth Amendment. The
signatory of Tenant represents to Landlord that he is duly authorized to execute
and deliver this Fourth Amendment on behalf of Tenant. The Lease together with
this Fourth Amendment constitutes and contains the sole and entire agreement of
the parties hereto with respect to the subject matter hereof and no prior or
contemporaneous oral or written representations or agreements between the
parties and relating to the subject matter hereof shall have any legal effect.
Effective immediately, and except for the options contained in Sections 7, 8 and
9 of this Fourth Amendment, any and all options, including without limitation,
expansion options, renewal options, termination options, extension options, and
rights of first refusal or negotiation, granted to Tenant pursuant to the Lease
are null and void and of no further force or effect. Effective immediately,
Landlord's option to relocate Tenant as set forth in Section 2 of the Second
Amendment is hereby null and void and of no further force and effect. The
submission of this Fourth Amendment for examination does not constitute an offer
to enter into a contract and this Fourth Amendment shall be effective only upon
execution hereof by Landlord and Tenant. Except as hereinabove provided, all
other terms and conditions of the Lease shall remain unchanged and in full force
and effect, and are hereby ratified and confirmed by the parties hereto. Tenant


                                       24
<PAGE>

hereby acknowledges and agrees that, as of the date hereof, the Lease is subject
to no offsets, claims, counterclaims or defenses of any nature whatsoever.
Landlord acknowledges and agrees that to its actual knowledge, without
investigation or inquiry, Tenant is not in default under the Lease. References
to the "knowledge" of Landlord contained in this Fourth Amendment shall refer
only to the actual knowledge of the Designated Employee (as hereinafter defined)
of Landlord, and shall not be construed, by imputation or otherwise, to refer to
any other officer, agent, manager, representative or employee of Landlord or any
affiliate thereof or to impose upon such Designated Employee any duty to
investigate the matter to which such actual knowledge, or the absence thereof,
pertains. As used herein, the term "Designated Employee" shall refer to Nancy
Bryan, the current property manager of the Project. This Fourth Amendment may
not be changed, modified, discharged or terminated orally in any manner other
than by an agreement in writing signed by Landlord and Tenant or their
respective heirs, representatives, successors and permitted assigns. If any
clause or provision of this Fourth Amendment is illegal, invalid or
unenforceable under present or future laws, the remainder of this Fourth
Amendment shall not be affected thereby, and in lieu of each clause or provision
of this Fourth Amendment which is illegal, invalid or unenforceable, there shall
be added as a part of this Fourth Amendment a clause or provision as nearly
identical to the said clause or provision as may be legal, valid and
enforceable.

         IN WITNESS WHEREOF, the parties hereto have executed this Fourth
Amendment on the day and year first above written.


                                 LANDLORD:
