           (d) If the Term commences at any time other than the first day of a
month or terminates at any time other than the last day of a month, the amount

"lockbox" or other depository whereby checks issued in payment of Rent are
initially cashed or deposited by a person or entity other than Landlord (albeit
on Landlord's authority), then, for any and all purposes under this Lease; (i)
Landlord shall not be deemed to have accepted such payment until ten (10) days
after the date on which Landlord shall have actually received such funds, and
(ii) Landlord shall be deemed to have accepted such payment if (and only if)
within said ten (10) day period, Landlord shall not have refunded (or attempted
to refund) such payment to Tenant. Nothing contained in the immediately
preceding sentence shall be construed to place Tenant in default of Tenant's
obligation to pay Rent if and for so long as Tenant shall timely pay the Rent
required pursuant to this Lease in the manner designated by Landlord.

            participate in the management, operation, repair, security or
            maintenance of any properties or buildings other than the Building,
            such expenses shall be proportionately allocated to the Building
            based upon the percentage of time devoted by such persons to the
            Building;

            (ii) All supplies and materials used in the operation and
            maintenance of the Property and Building;

            and whether imposed by taxing districts or authorities presently
            taxing the Property and Building or by others, subsequently created
            or otherwise, and any other taxes and assessments attributable to
            the Property and Building or its operation, but excluding federal
            and state taxes on income, death taxes, franchise taxes,
            development or impact taxes which relate solely to the Property,
            and any taxes imposed or measured on or by the income of Landlord
            from the operation of the Property or imposed in connection with
            any change of ownership of the Property (collectively, the "Real
            Estate Taxes") together with any reasonable attorneys' or
            consultants' fees incurred with respect to issues or concerns
            involving the Real Estate Taxes for the Building, the Property, or
            both; PROVIDED, HOWEVER, that if at any time during the Term, the
            present method of taxation or assessment shall be so changed that
            the whole or any part of the taxes, assessments, levies,
            impositions or charges now levied, assessed or imposed on real
            estate and the improvements thereof shall be changed and as a
            substitute thereof, or in lieu of, taxes, assessments, levies,
            impositions or charges shall be levied, assessed or imposed wholly
            or partially as a capital levy or otherwise on the rents received
            from the Property or the rents reserved herein or any part thereof,
            then such substitute or additional taxes, assessments, levies,
            impositions or charges, to the extent so levied, assessed or

                                      -3-

            imposed, shall be deemed to be included within the Real Estate
            Taxes to the extent that such substitute or additional tax would be
            payable if the Property were the only property of Landlord subject
            to such tax.

            (vii) Cost of repairs and general maintenance of the interior and
            exterior of the Property and Building (including, but not limited

            revenues and other expenses incurred for the general operation and
            management of the Property and Building;

            (ix) Amortization costs due to any capital expenditures incurred
            (i) which have the effect of reducing or limiting Operating Costs
            of the Property and Building, if such reduction or limitation
            inures to Tenant's benefit (but only to the extent and in the
            amount that such Operating Costs of the Property and Building are
            reduced), or (ii) which may be required by governmental authority
            (as set forth in item (xii) below) or by Landlord's insurance
            carrier (but only to the extent and in the amount that such
            Operating Costs of the Property and Building are reduced), or (iii)
            which improve or enhance the health of persons in the Building or
            the safety of the Building;

            (xxiii) The costs of any modifications made to the Building that
            are required by any applicable governmental laws, ordinances,
            codes, rules and regulations (including without limitation, Title
            III of the Americans with Disabilities Act of

                                      -5-
<PAGE>   9

            1990) as enacted, in effect, interpreted and enforced prior to the
            Commencement Date of this Lease;

            (xxiv) Costs incurred by Landlord due to the violation by Landlord
            of the terms and conditions of any lease of space in the Building
            or of the terms and conditions of any law, rule, regulation, order
            or other governmental requirement of any authority having

            (xxvi) The cost of acquisition or leasing of any items of "fine
            art" (rather than decorative art or seasonal decorations).

           (d) The term "Tenant's Share" shall mean the proportion that the
Square Feet in the Premises bears to ninety-five percent (95%) of the Total
Building Rentable Area, or the average percentage of the Total Building
Rentable Area actually leased in the Building for any calendar year, if such
average is greater than ninety-five percent (95%) of the Total Building
Rentable Area. The average shall be determined by adding together the total
leased space on the last day of each month during the calendar year in question
and dividing by twelve (12). Tenant's Share is used in this Lease to determine
the portion of Operating Costs payable by Tenant, on a per square foot per
annum basis. Notwithstanding anything to the contrary contained herein, if the
Building is not fully occupied during any calendar year (including calendar
year 2000), appropriate adjustments shall be made to determine Operating Costs
as though the Building had been fully occupied in such calendar year for the
entire calendar year. In no event shall Landlord be entitled to collect from
all tenants of the Building more than one hundred percent (100%) of Operating
Expenses applicable to the Building.

           (e) On January 15 of each calendar year after the calendar year in
which this Lease is executed (or as soon thereafter as practical if for reasons
beyond Landlord's reasonable control), Landlord shall provide Tenant with the
projected Operating Costs for such current calendar year, and Tenant shall
thereafter pay Tenant's Share of projected Operating Costs for operating the
Property and Building in excess of the Initial Operating Costs. Such projected
Operating Costs in excess of Initial Operating Costs shall be payable in
advance on a monthly basis by paying one-twelfth (1/12th) of such amount during
each month of such respective calendar year. If Landlord has not furnished
Tenant such comparison by January 15, Tenant shall continue to pay on the basis
of the prior year's estimate until the month after such comparison is given.
Landlord shall, within one hundred twenty (120) days (or as soon thereafter as
practical) after the end of each calendar year during the Term provide Tenant
an unaudited statement of such year's actual Operating Costs. If actual
Operating Costs are greater than projected Operating Costs, Tenant shall pay
Landlord, within thirty (30) days of such statement's receipt, Tenant's Share
of the difference thereof. If such year's projected Operating Costs are greater
than the actual Operating Costs, Landlord shall refund to Tenant, within thirty
(30) days of such statement issuance, Tenant's Share of the difference between
projected Operating Costs and actual Operating Costs.

           (f) If this Lease commences at any time other than the first day of
a calendar year or terminates at any time other than the last day of a calendar
year the amount of Operating Costs due from Tenant shall be proportionately
adjusted based on that portion of the year that this Lease was in effect.

           (g) Tenant's payments of Operating Costs shall not be deemed
payments of base rental under any governmental wage and price controls or
analogous governmental actions affecting the amount of Rent which Landlord may
charge Tenant for the Premises.

           (h) In the event that within one (1) year after Tenant's receipt of
Landlord's Statement for the prior calendar year, Tenant reasonably believes
that certain of the Operating Costs charged by Landlord include costs that are
not properly included within the term "Operating Costs" or that Landlord has
erred in calculating same, Tenant shall have the right to audit Landlord's
books and records in accordance with this paragraph. Tenant shall exercise

                                      -6-
<PAGE>   10

such audit right by providing Landlord with a written notice of Tenant's
exercise of such audit right within such one (1) year period and a statement
enumerating reasonably detailed reasons for Tenant's objections to the
statement issued by Landlord (the "Audit Notice"). Upon the receipt by Landlord
of the Audit Notice, Landlord shall instruct its property manager at the
Building to meet with a designated employee of Tenant (the "Tenant
Representative") to discuss the objections set forth in the Audit Notice.
Landlord shall provide the Tenant Representative with reasonable access to
Landlord's books and records at the Building relating to Operating Costs for
the calendar year in question in order to attempt to resolve the issues raised
by Tenant in the Audit Notice. If, within thirty (30) days after Landlord's
receipt of the Audit Notice, Landlord and Tenant are unable to resolve Tenant's
objections, then no later than ten (10) days after the expiration of such
30-day period, Tenant shall notify Landlord if Tenant wishes to employ an
independent, reputable certified public accounting firm charging for its
services on an hourly rate (and not a contingent fee) basis (unless such firm
is one of the "Big 5" or an affiliate thereof or successor thereto and uses
generally accepted accounting practices) ("Acceptable Accountants") to inspect
and audit Landlord's books and records for the Building to the objections
raised in Tenant's statement. Such audit shall be limited to a determination of
whether or not Landlord calculated the Operating Costs in accordance with the
terms and conditions of this Lease and normal and customary accounting methods
used by owners of similar buildings in the area in calculating the increase of
Operating Costs. All costs and expenses of any such audit shall be paid by
Tenant unless Landlord has overstated Operating Costs by more than five percent
(5%), in which case Landlord shall reimburse Tenant for Tenant's reasonable and
actual out-of-pocket expenses of such audit (not to exceed the amount of
Tenant's Share of such overcharge). Any audit performed pursuant to the terms
of this Section shall be conducted only by the Acceptable Accountants at the
offices of Landlord's property manager at the Building. Notwithstanding
anything contained herein to the contrary, Tenant shall be entitled to exercise
its audit right pursuant to this section only in strict accordance with the
foregoing procedures no more often than once per calendar year and each such
audit shall relate to the calendar year most recently ended; provided, however,
if Tenant discovers overcharges in Landlord's statement, Tenant shall be
entitled to audit the prior years' books and records (but in no event beyond
the date of Tenant's most recent prior audit) with respect to the item(s) for
which such overcharge is discovered. In the event that Tenant fails to notify
Landlord within the foregoing one year period that Tenant objects to Landlord's
statement, then Tenant's right to audit such year's statement shall be null and
void.

       4. DELIVERY OF THE PREMISES
         ------------------------

                  Landlord shall deliver possession of the Premises to Tenant,
with the improvements to be constructed pursuant to EXHIBIT "C", attached hereto
and by this reference incorporated herein, substantially complete on the
Commencement Date. If Landlord for any reason whatsoever cannot deliver
possession of the Premises, with the improvements to be constructed pursuant to
EXHIBIT "C" substantially complete to Tenant at the Commencement Date, this
Lease shall not be void or voidable, nor shall Landlord be liable to Tenant for
any loss or damage resulting therefrom. If the delay is not due to any of the
reasons set forth in Article 3 of EXHIBIT "C", Monthly Rental shall be waived
for the period between the Commencement Date and the date which Landlord
delivers possession of the Premises to Tenant. If the delay is due to any of
said reasons in Article 3 of EXHIBIT "C", Monthly Rental shall commence as of
the Commencement Date. Notwithstanding anything to the contrary contained
herein, if (a) Landlord is responsible for the build-out of the Premises and
Landlord does not achieve Substantial Completion with respect to the Premises on
or before September 1, 2001 then Tenant shall have the right to terminate this
Lease with notice to Landlord on or before September 11, 2001, or (b) if Tenant
is responsible for the build-out of the Premises and Landlord does not deliver
the Premises to Tenant on or before January 1, 2001, then Tenant shall have the
right to terminate this Lease with notice to Landlord on or before January 10,
2001. Failure by Tenant to provide notice to Landlord on a timely basis shall be
deemed a waiver of this right to terminate.

                  In addition to the foregoing, provided Tenant is not in
default (after the expiration of any applicable notice and cure period) under
its current lease of the 6th floor space in the Building, in the event the
Commencement Date does not occur on or before September 1, 2000, except for a
delay cause by Force Majeure or Tenant Delay (as that term is defined in EXHIBIT
"C"), then Tenant shall (i) be entitled to a rental abatement of one (1) day for
each day that elapses between September 1, 2000 and the actual Commencement Date
(which rental abatement shall commence

                                      -7-
<PAGE>   11

upon the actual Commencement Date). In the event that Tenant receives such an
abatement of Monthly Rental pursuant to the foregoing terms, the Term of this
Lease shall be extended one (1) day for each day of Rent abatement Tenant
receives such that Tenant shall (subject to early termination of this Lease in
accordance with Special Stipulations Number 6) pay 11 years of all Rent due
hereunder.

      5. ACCEPTANCE OF THE PREMISES
         --------------------------

           The taking of possession of the Premises by Tenant shall be
conclusive evidence that Tenant accepts the same "as is" and that said Premises
and the Building were in good and satisfactory condition for the use intended
at the time such possession was taken, subject to latent defects disclosed by
Tenant during the first Lease Year and "punch-list" items which Landlord agrees
to remedy within a reasonable time after Tenant's delivery of notice of the
same to Landlord. Tenant shall execute and deliver an "Acceptance of Premises"
agreement upon the taking of possession of the Premises, in the form attached
as EXHIBIT "B", by this reference incorporated herein.

      6. USE AND COMPLIANCE
         ------------------

           Tenant shall use the Premises only for professional, executive
office purposes, generally in accordance with the manner of use by other
tenants in the Building. Tenant shall also be entitled to use a portion of the
Premises for a computer room and show room for Tenant's products, provided that
Tenant shall not conduct any retail sales within the Premises. The occupancy
rate of the Premises shall in no event be more than one (1) person per 200
rentable square feet within said Premises. Tenant shall conduct its business in
the manner and according to the generally accepted business principles of the
business or profession in which Tenant is engaged. Tenant's use of the Premises
shall not violate any ordinance, law or regulation of any governmental body or
the "Rules and Regulations" of Landlord (the "Rules") as set forth in EXHIBIT
"E" attached hereto and made a part hereof, or cause an unreasonable amount of
use of any of the services provided in the Building.

      7. TENANT'S CARE OF THE PREMISES
         -----------------------------

           (a) Tenant will maintain the Premises and the fixtures and
appurtenances therein in a first-class condition, normal wear and tear and
casualty excepted, and will not commit or permit waste therein. Any repair
work, maintenance and any alterations permitted by Landlord in the Premises (i)
shall be done at Tenant's sole cost and expense; (ii) shall, with respect to
material alternations or repairs which affect building systems, be done by
Landlord's employees or agents or, with Landlord's consent, by persons
requested by Tenant; and (iii) shall first be consented to by Landlord;
provided that Landlord shall not unreasonably withhold or delay its consent for
interior, non-structural alterations. Tenant shall, at Tenant's expense, but
under the direction of Landlord and performed by Landlord's employees or
agents, or with Landlord's consent, by persons requested by Tenant and
consented to by Landlord, promptly repair any injury or damage to the Premises
or Building caused by the misuse or neglect thereof by Tenant, by Tenant's
contractors, subcontractors, customers, employees, licensees, agents, or
invitees (but only to the extent not covered by insurance required to be
maintained by Landlord under this Lease).

           (b) Tenant agrees to be wholly responsible at Tenant's sole cost and
expense for the compliance of the Premises with the provisions of the Americans
With Disabilities Act of 1990, as amended (the "ADA"). If it is determined that
the interior, nonstructural portions of the Premises are not in compliance with
the ADA to at least the minimum extent required under regulations then in
effect, Tenant as its sole obligation, shall cause the interior, nonstructural
portions of the Premises to be in compliance. Landlord hereby agrees to be
responsible, at its sole cost and expense (subject to reimbursement by tenants
of the Building including Tenant to the extent expressly provided elsewhere in
this Lease) for the compliance of the Building with all such rules,
regulations, laws and ordinances, unless such compliance arises out of Tenant's
specific use of the Premises. Notwithstanding anything to the contrary
contained in this Lease, Landlord shall be wholly responsible at Landlord's
sole cost and expense for the compliance of the bathrooms, stairwell and
elevator core located within and/or serving the 7th and 8th floors of

                                      -8-
<PAGE>   12

the Building with all governmental laws, ordinances, regulations, codes and
rules enacted and applicable prior to the Commencement Date of this Lease.

           (c) Tenant will not, without Landlord's prior consent, make
alterations, additions or improvements (including, but not limited to,
structural alterations, additions or improvements but excluding cosmetic
alterations such as painting, wall coverings and floor coverings and other
improvements which do not affect the Building Systems and do not cost in excess
of $25,000.00 and provided Tenant gives Landlord notice of such work at least
10 days prior to installation) in or about the Premises and will not do
anything to or on the Premises which will increase the rate of insurance on the
Building or the Property. All alterations, additions or improvements of a
permanent nature made or installed by Tenant to the Premises shall become the
property of Landlord at the expiration or early termination of this Lease.
Landlord reserves the right to require Tenant to remove any improvements or
additions made to the Premises by Tenant and to repair and restore the Premises
to their condition prior to such alteration, addition or improvement,
reasonable wear and tear, unrepaired casualty and condemnation excepted,
provided Landlord has notified Tenant at the time Tenant requests the right to
make such alteration, addition or improvement that such item must be removed by
Tenant at the expiration or early termination of the Term.

           (d) No later than the last day of the Term, Tenant will remove
Tenant's personal property and repair injury done by or in connection with
installation or removal of said property and surrender the Premises (together
with all keys, access cards or entrance passes to the Premises and/or the
Building) in as good a condition at the beginning of the Term, reasonable wear
and tear, unrepaired casualty and condemnation excepted. All property of Tenant
remaining in the Premises after expiration or early termination of the Term
shall be deemed conclusively abandoned and may be removed by Landlord, and
Tenant shall reimburse Landlord for the cost of removing the same, subject
however, to Landlord's right to require Tenant to remove any improvements or
additions made to the Premises by Tenant pursuant to the preceding Paragraph.

           (e) In doing any work on the installation of Tenant's furnishings,
fixtures, or equipment in the Premises, Tenant will use only contractors or
workers consented to by Landlord prior to the time such work is commenced.
Landlord may condition its consent upon its receipt from such contractors or
workers of acceptable (i) lien waivers; and (ii) evidence of liability and
personal property insurance coverage in amounts and with insurance carriers
satisfactory to Landlord. Tenant shall promptly remove any lien or claim of
lien for material or labor claimed against the Premises or Building, or both,
by such contractors or workers if such claim should arise, and hereby
indemnifies and holds Landlord harmless from and against any and all loss,
cost, damage, expense or liabilities including, but not limited to, reasonable
attorney's fees, incurred by Landlord, as a result of or in any way related to
Tenant's failure to timely remove such claims or liens.

           (f) All personal property brought into the Premises by Tenant, its
employees, licensees and invitees shall be at the sole risk of Tenant, and
Landlord shall not be liable for theft thereof or of money deposited therein or
for any damages thereto, unless caused by the negligence or willful misconduct
of Landlord.

            (b) The services provided in Paragraph 8(a) are predicated on and
            are in anticipation of the use of the Premises as follows:

            (i) Services shall be provided for the Building during normal
            business hours (except as otherwise expressly set forth herein) as
            described in the Rules.

            (ii) HVAC design is based on sustained outside temperatures being
            no higher than 95 degrees Fahrenheit and no lower than 14 degrees
            Fahrenheit with sustained occupancy of the Premises by no more than
            one person per 150 square feet of floor area and heat generated by
            electrical lighting and fixtures not to exceed 3.0 watts per square
            foot.

            (iii) Electric power usage and consumption for the Premises shall
            be based on lighting of the Premises during normal business hours

            volt, 20 amp circuits (allowable load of 15 amps). Heavier use
            items shall not be used or installed, unless expressly permitted

            electrical consumption, or if Tenant's electrical design requires
            low voltage or high voltage circuits in excess of Tenant's share of
            the Building standard circuits, as such share is determined by
            Landlord in Landlord's reasonable judgment, Landlord may (at
            Tenant's expense), if reasonably possible, install within the
            Building one (1) additional high voltage panel and/or one (1)
            additional low voltage panel with associated transformer (the
            "Additional Electrical Equipment") as necessary to accommodate the
            aforesaid requirements.

                                     -10-
<PAGE>   14

            If the Additional Electrical Equipment is installed because
            Tenant's low or high voltage rated electrical design load exceeds
            the applicable Building standard rated electrical design load (on a
            per square foot basis), then a meter may also be added by Landlord
            (at Tenant's expense) to measure the electricity provided through
            the Additional Electrical Equipment.

           (c) If Tenant uses any services in an amount or for a period in
excess of that provided for herein, Landlord also reserves the right to charge
Tenant reimbursement for the cost of such added services. Current charges for
after hours HVAC are $30.00 per hour for the first floor and $10.00 per hour
for each subsequent floor. Landlord reserves the right to install separate
metering devices to determine such excessive periods and/or amounts, at
Tenant's sole cost and expense. If there is disagreement as to such additional
charge, the opinion of the appropriate local utility company or an independent
professional engineering firm shall prevail.

           (d) Landlord shall not be liable for any damages directly or
indirectly, and Tenant shall have no right of set-off or reduction in Rent,
resulting from the installation, use, malfunction, or interruption of use of
any equipment in connection with the furnishing of services referred to herein,
including, but not limited to, any interruption in services by any cause beyond
the immediate control of the Landlord; provided however, Landlord shall
exercise due care in furnishing adequate and uninterrupted services. Without
limitation on the foregoing, under no circumstances shall Landlord incur
liability for damages caused directly or indirectly by any malfunction of
Tenant's computer systems resulting from or arising out of the failure or
malfunction of any electrical, air conditioning or other system serving the
Building, and Tenant hereby expressly waives the right to make any such claim
against Landlord.

           (e) Notwithstanding anything to the contrary contained in Section
8(d) above, if Tenant cannot reasonably use the Premises for Tenant's intended
business operations by reasons of any interruption in services to be provided
by Landlord (and the Premises is untenantable for Tenant's use, in Tenant's
reasonable business judgment) and such interruption is caused by the negligence
of Landlord, and such condition exists for three (3) business days, then
Tenant's Monthly Rental shall be equitably abated for that portion of the
Premises that Tenant is unable to use for Tenant's intended business operations
until such service is restored to the Premises. If any interruption in such
services is due to the willful misconduct of Landlord or its employees,
Tenant's Monthly Rental shall be equitably abated immediately following
Tenant's notice to Landlord of such interruption. Tenant shall not, however, be
entitled to any abatement of Monthly Rental if the interruption or abatement in
service or the failure by Landlord to furnish such service is due to a cause
beyond Landlord's control (an "Unavoidable Interruption"), except if and to the
extent Landlord's loss of such rents with respect to the Unavoidable
Interruption is reimbursed by Landlord's insurance (or would have been
reimbursed had Landlord carried rental loss insurance required by this Lease).
By way of example only, there shall be no abatement of Monthly Rental if
Landlord is unable to furnish water or electricity to the Premises if no water
or electricity is then being made available to the Building by the supplying
utility company or municipality, unless Landlord's loss of rents with respect
to such Unavoidable Interruption is or would have been reimbursed by Landlord's
insurance as described in the previous sentence. At the time of the loss of
service, Tenant must give written notice promptly to Landlord of the loss of
service and its claim for abatement and Tenant only shall be entitled to
abatement of Monthly Rental in proportion to the area rendered unusable.
Landlord may prevent or stop an abatement by providing substantially the same
service in similar quality and quantity by temporary or alternative means until
the service can be restored. Such abatement shall be Tenant's sole remedy for
loss of service and Tenant shall have no right to terminate this Lease.

      9. ELECTRONIC SERVICES
         -------------------

           (a) Tenant may, in a matter consistent with the provisions and
requirements of this Lease, install, maintain, replace, remove or use any
communications or computer or other electronic service wires, cables and
related devices (collectively, the "Lines") at the Building in or serving the
Premises, provided: (a) Tenant shall obtain Landlord's prior written consent,
which consent may be conditioned as reasonably required by Landlord, (b) if
Tenant at any time uses any equipment that may create an electromagnetic field
exceeding the normal insulation ratings of ordinary twisted pair riser cable or
may cause radiation higher than normal background radiation, the Lines therefor
(including riser cables) shall be appropriately insulated to prevent such
excessive electromagnetic fields or radiation, and (c) Tenant shall pay all
costs in connection therewith. Landlord reserves the right to require that
Tenant remove any Lines which are installed in violation of these provisions.
Tenant shall not, without the prior written consent of Landlord in each
instance, grant to any third party a security interest or lien in or on the
Lines, and any such security interest or lien granted without Landlord's
written consent shall be null and void.

           (b) As used herein "Electronic Services Provider" means a business
which provides telephone, telegraph, telex, video, other telecommunications or
other services which permit Tenant to receive or transmit information by the
use of electronics and which require the use of wires, cables, antennas or
similar devices in or on the Building. The services of Electronic Services
Providers are sometimes referred to herein as "Electronic Services."

           (c) Landlord shall have no obligation (a) to install any Electronic
Services equipment or facilities, (b) to make available to Tenant the services
of any particular Electronic Services Provider, (c) to allow any particular
Electronic Services Provider access to the Building, or (d) to continue to
grant access to an Electronic Services Provider once such provider has been
given access to the Building. Landlord may (but shall not have the obligation
to): (x) install new Lines at the property, (y) create additional space for
Lines at the property, and (z) adopt reasonable and uniform rules and
regulations with respect to the Lines.

           (d) Tenant acknowledges and agrees that all Electronic Services
desired by Tenant shall be ordered and utilized at the sole expense of Tenant.
Unless Landlord otherwise requests or consents in writing, all of Tenant's
Electronic Services equipment shall be and remain solely in the Tenant's
Premises and the telephone closet(s) on the floor(s) on which Tenant's Premises
is located, in accordance with rules and regulations adopted by Landlord from
time to time. Unless otherwise specifically agreed to in writing, Landlord
shall have no responsibility for the maintenance of Tenant's Electronic
Services equipment, including Lines, nor for any Lines or other infrastructure
to which Tenant's Electronic Services equipment may be connected. Tenant agrees
that, to the extent any Electronic Services are interrupted, curtailed or
discontinued, Landlord shall have no obligation or liability with respect
thereto and it shall be the sole obligation of Tenant at its own expense to
obtain substitute service. Except to the extent arising from the intentional or
negligent acts of Landlord or Landlord's agents or employees, (i) Landlord
shall have no liability for damages arising from, and Landlord does not warrant
that Tenant's use of any Lines will be free from the following (collectively,
the "Line Problems"): (a) any eavesdropping or wire-tapping by unauthorized
parties, (b) any failure of any Lines to satisfy Tenant's requirements, or (c)
any shortages, failures, variations, interruptions, disconnections, loss or
damage caused by the installation, maintenance, replacement, use or removal of
Lines by or for other tenants or occupants at the property, and (ii) such Line
Problems shall not be deemed an actual or constructive eviction of Tenant,
render Landlord liable to Tenant for abatement of Monthly Rental, or relieve
Tenant from performance of Tenant's obligations under this lease. Unless caused
by the negligence or willful misconduct of Landlord, Landlord in no event shall
be liable for damages by reason of loss or profits, business interruption or
other consequential damage arising from any Line Problems.

           (e) Landlord shall have the right, upon reasonable prior notice to
Tenant, to interrupt or turn off Electronic Services facilities in the event of
emergency or as necessary in connection with maintenance, repairs or
construction at the Building or installation of Electronic Services equipment
for other tenants in the Building or on account of violation by the Electronic
Services Provider or owner of the Electronic Services equipment of any
obligation to Landlord or

                                     -12-
<PAGE>   16

in the event that Tenant's use of the Electronic Services infrastructure of the
Building materially interferes with the Electronic Services of other tenants in
the Building.

           (f) Any and all Electronic Services equipment installed in the
Tenant's Premises or elsewhere in the Building by or on behalf of Tenant,
excluding Lines, or other facilities for Electronic Services reception or
transmittal, shall be removed prior to the expiration or earlier termination of
the Lease term, by Tenant at its sole cost or, at Landlord's election, by
Landlord at Tenant's sole cost, with the cost thereof to be paid as Additional
Rent. Landlord shall have the right, however, upon written notice to Tenant
given no later than thirty (30) days prior to the expiration or earlier
termination of the Lease term (except that the notice period shall extend to
thirty (30) days beyond the date of termination of the Lease if it is
terminated by either party due to a default by the other), to require Tenant to
abandon and leave in place, without additional payment to Tenant or credit
against Rent, any and all Electronic Services, Lines and related
infrastructure, or selected components thereof, whether located in the Tenant's
Premises or elsewhere in the Building.

           (g) In the event that Tenant wishes at any time to utilize the
services of an Electronic Services Provider whose equipment is not then
servicing the Building, no such Electronic Services Provider shall be permitted
to install its Lines or other equipment within the Building without first
securing the prior written approval of Landlord. Landlord's approval shall not
be deemed any kind of warranty or representation by Landlord, including,
without limitation, any warranty or representation as to the suitability,
competence, or financial strength of the Electronic Services Provider. Without
limitation of the foregoing standard, unless all of the following conditions
are satisfied to Landlord's satisfaction, it shall be reasonable for Landlord
to refuse to give its approval: (a) Landlord shall incur no current expense or
risk or future expense whatsoever with respect to any aspect of the Electronic
Services Provider's provision of its Electronic Services, including without
limitation, the costs of installation, materials and services; (b) prior to
commencement of any work in or about the Building by the Electronic Services
Provider, the Electronic Services Provider shall supply Landlord with such
written indemnities, insurance, financial statements, and such other items as
Landlord reasonably determines to be necessary to protect its financial
interests and the interests of the Building relating to the proposed activities
of the Electronic Services Provider; (c) the Electronic Services Provider
agrees to abide by such rules and regulations, Building and other codes, job
site rules and such other requirements as are reasonably determined by Landlord
to be necessary to protect the interests of the Building, the tenants in the
Building, and Landlord, in the same or similar manner as Landlord has the right
to protect itself and the Building with respect to proposed alterations as
described in Article 7 of this Lease; (d) Landlord reasonably determines that,
considering other potential uses for space in the Building, there is sufficient
space in the Building for the placement of all of the Electronic Services
Provider's equipment, conduit, Lines and other materials; (e) the Electronic
Services Provider agrees to abide by Landlord's requirements, if any, that the
Electronic Services Provider use existing Building conduits and pipes or use
Building contractors (or other contractors approved by Landlord); (f) Landlord
is reasonably compensated for space used in the Building for the storage and
maintenance of the Electronic Services Provider's equipment, for the fair
market value of the Electronic Services Provider's access to the Building, for
the use of common or core space within the Building and the costs which may
reasonably be expected to be incurred by Landlord; (g) the Electronic Services
Provider agrees to deliver to Landlord detailed "as built" plans immediately
after the installation of the Electronic Services Provider's equipment is
complete; and (h) all of the foregoing matters are documented in a written
license agreement between Landlord and the Electronic Services Provider, the
form and content of which is reasonably satisfactory to Landlord.

           (h) Notwithstanding any provision of the proceeding paragraphs to
the contrary, the refusal of Landlord to grant its approval to any prospective
Electronic Services Provider shall not be deemed a default or breach by
Landlord of its obligation under this Lease unless and until Landlord is
adjudicated to have acted unreasonably, recklessly or maliciously with respect
to Tenant's request for approval, and in that event, Tenant shall still have no
right to terminate the Lease or claim an entitlement to rent abatement, but
may, as Tenant's sole and exclusive recourse seek a judicial order of specific
performance compelling Landlord to grant its approval as to the prospective
provider in question. The provisions of this paragraph may be enforced solely
by Tenant and Landlord, are not for the benefit of any other party, and
specifically but without

                                     -13-
<PAGE>   17

limitation, no telephone or other Electronic Services Provider shall be deemed
a third party beneficiary of this Lease.

           (i) Tenant shall not utilize any wireless Electronic Services
equipment (other than usual and customary cellular telephones), including
antennae and satellite receiver dishes, within the Tenant's Premises, within
the Building or attached to the outside walls or roof of the Building, without
Landlord's prior written consent. Such consent may be conditioned in such a
manner so as to protect Landlord's financial interests and the interests of the
Building, and the other tenants therein, in a manner similar to the
arrangements described in the immediately preceding paragraphs.

           (j) In the event that Electronic Services equipment, Lines and
facilities or satellite and antennae equipment of any type installed by or at
the request of Tenant within the Tenant's Premises, on the roof, or elsewhere
within or on the Building causes interference to equipment used by another
party, Tenant shall cease using such equipment, Lines and facilities or
satellite and antennae equipment until the source of the interference is
identified and eliminated and Tenant shall assume all liability related to such
interference. Tenant shall cooperate with Landlord and other parties, to
eliminate such interference promptly. In the event that Tenant is unable to do
so, Tenant will substitute alternative equipment which remedies the situation.
If such interference persists, Tenant shall, at Landlord's sole discretion,
remove such equipment.

      10. DESTRUCTION OR DAMAGE TO PREMISES
          ---------------------------------

           (a) If the Premises or the Building are totally destroyed (or so
substantially damaged as to be untenantable in the reasonable determination of
the Architect of the Building) by storm, fire, earthquake or other casualty,
Landlord shall have the option to:

            (i) Terminate this Lease as of the date of the occurrence of the
            storm, earthquake, fire or other casualty by giving notice to
            Tenant within sixty (60) days from the date of such damage or
            destruction; or

            (ii) Commence the process of restoration of the Premises to a
            tenantable condition within sixty (60) days from the date of such
            casualty, and proceed with due diligence to complete said
            restoration of the Premises. If Landlord chooses to restore the
            Premises, Rent shall abate with respect to the untenantable portion
            of the Premises from the date of such casualty until the date of
            substantial restoration thereof.

If, for any reason other than Tenant Delay (relating to the restoration of the
Premises), Landlord fails to substantially complete any restoration following
any full or partial casualty within one hundred eighty (180) days of the date of
the casualty, this Lease may be terminated as of the date of the casualty upon
notice from either party to the other, given not more than ten (10) business
days following the expiration of said one hundred eighty (180) day period. If
such notice is not given, this Lease shall remain in force and effect and Rent
shall commence upon delivery of the Premises to Tenant in a tenantable condition
(evidenced by notice to Tenant that the Premises are substantially completed).

           (b) If the Premises are damaged but not rendered wholly untenantable
by any event set forth in Paragraph 9(a) above such that critical functions
within the Premises of Tenant are working sufficiently as to allow Tenant to
conduct normal business activity in at least a portion of the Premises, Rent
shall abate in the proportion the Premises have been made untenantable.
Landlord shall restore the Premises expeditiously, and upon the date of
restoration, full Rent shall commence. Notwithstanding the foregoing, if
Landlord is unable to substantially complete restoration of the Premises within
one hundred eighty (180) days following the casualty, this Lease may be
terminated by either party upon written notice to the other given no more than
five (5) days following the expiration of said one hundred eighty (180) day
period.

      11. DEFAULT BY TENANT; LANDLORD'S REMEDIES
          --------------------------------------

           (a) The occurrence of any of the following shall constitute an Event
of Default hereunder by Tenant:

            (i) The Rent or any other sum of money due of Tenant hereunder is
            not paid within five (5) business days following Tenant's receipt
            of written notice of such nonpayment from Landlord, provided that
            Landlord shall not be required to provide such notice and
            opportunity to cure more than (2) times in any calendar year during
            the Term;

            (ii) The Premises are abandoned or vacated for a period in excess
            of ninety (90) consecutive days and Tenant shall have failed to pay
            Rent hereunder and maintain the Premises for such period in
            accordance with its obligations under this Lease;

            (iii) Any petition is filed by or against Tenant under any section
            or chapter of the National or Federal Bankruptcy Act or any other
            applicable Federal or State bankruptcy, insolvency or other similar
            law, and, in the case of a petition filed against Tenant, such
            petition is not dismissed within thirty (30) days after the date of
            such filing; if Tenant shall become insolvent or transfer property
            to defraud creditors; if Tenant shall make an assignment for the
            benefit of creditors; or if receiver is appointed for more than 85%
            of Tenant's assets;

            (iv) Tenant fails to bond off or otherwise remove any lien filed
            against the Premises or the Building by reason of Tenant's actions,
            within ten (10) days after Tenant has notice of the filing of such
            lien;

            (v) Tenant fails to observe, perform and keep the covenants,
            agreements, provisions, stipulations, conditions and Rules herein
            contained to be observed, performed and kept by Tenant (other than
            the failure to pay when due any Rent or any other sum of money
            becoming due Landlord hereunder, which under all circumstances is
            governed by and subject to Paragraph 10(a)(i) herein), and persists
            in such failure after thirty (30) days written notice by Landlord
            requiring that Tenant remedy, correct, desist or comply (or if any
            such failure to comply on the part of Tenant would reasonably
            require more than thirty (30) days to rectify, unless Tenant
            commences rectification within the thirty (30) day notice period
            and thereafter promptly, effectively and continuously proceeds with
            the rectification of the failure to comply on the part of Tenant
            and, in all such events, cures such failure to comply on the part
            of Tenant no later than ninety (90) days after such notice).

           (b) Upon the occurrence of an Event of Default, Landlord shall have
the option to do and perform any one or more of the following:

            (i) Terminate this Lease, in which event Tenant shall immediately
            surrender the Premises to Landlord. If Tenant shall fail to do so,
            Landlord may, without further notice and without prejudice to any
            other remedy Landlord may have, lawfully enter upon the Premises
            without the requirement of resorting to the dispossessory procedures
            set forth in O.C.G.A. secs. 44-7-50 ET SEQ. and expel or remove
            Tenant and Tenant's effects without being liable for any claim for
            trespass or damages therefor. Upon any such termination, Tenant
            shall remain liable to Landlord for damages, due and payable monthly
            on the day Rent would have been payable hereunder, in an amount
            equal to the Rent and any other amounts which would have been owing
            by Tenant for the balance of the Term, had this Lease not been
            terminated, less the net proceeds, if any, of any reletting of the
            Premises by Landlord, after deducting all of Landlord's costs and
            expenses (including, without limitation, advertising expenses and
            professional fees) incurred in connection with or in any way related
            to the termination of this Lease, eviction of Tenant and such
            reletting; and/or

                                     -15-
<PAGE>   19

            (ii) With respect only to a monetary default and so long as Simmons
            Company is the primary obligor under this Lease (and otherwise
            applicable to any default hereunder), declare the entire amount of
            Rent calculated on the current rate being paid by Tenant, and other
            sums which in Landlord's reasonable determination would become due
            and payable during the remainder of the Term (including, but not
            limited to, increases in Rent pursuant to Paragraph 2(b) and 3(d)
            herein), discounted to present value by using a reasonable discount
            rate selected by Landlord, to be due and payable immediately. Upon
            such acceleration of such amounts, Tenant agrees to pay the same at
            once, together with all Rent and other amounts theretofore due,
            less the market value of the Premises for the remainder of the
            Term, as determined by Landlord (taking into consideration the
            probable costs of marketing and reletting the Premises,
            then-current rental rates, probable rental rates for the remainder
            of the Term, probable concession packages, the probability of
            reletting the Premises and the probable amount of time which will
            elapse before the Premises are relet), at Landlord's address as
            provided herein; provided however, that such payment shall not
            constitute a penalty or forfeiture but shall constitute liquidated
            damages for Tenant's failure to comply with the terms and
            provisions of this Lease (Landlord and Tenant agreeing that
            Landlord's actual damages in such an event are impossible to
            ascertain and that the amount set forth above is a reasonable
            estimate thereof). The acceptance of such payment by Landlord shall
            not constitute a waiver of rights or remedies to Landlord for any
            failure of Tenant thereafter occurring to comply with any term,
            provision, condition or covenant of this Lease; and/or

            (iii) Lawfully enter the Premises as the agent of Tenant without
            the requirement of resorting to the dispossessory procedures set
            forth in O.C.G.A. secs. 44-7-50 ET SEQ. and without being liable for
            any claim for trespass or damages therefor, and, in connection
            therewith, rekey the Premises, remove Tenant's effects therefrom
            and store the same at Tenant's expense, without being liable for
            any damage thereto, and relet the Premises as the agent of Tenant,
            without advertisement, by private negotiations, for any term
            Landlord deems proper, and receive the rent therefor. Tenant shall
            pay Landlord on demand any deficiency that may arise by reason of
            such reletting, but Tenant shall not be entitled to any surplus so
            arising. Tenant shall reimburse Landlord for all reasonable costs
            and expenses (including, without limitation, advertising expenses
            and reasonable professional fees) incurred in connection with or in
            any way related to the eviction of Tenant and reletting the
            Premises. Landlord, in addition to but not in lieu of or in
            limitation of any other right or remedy provided to Landlord under
            the terms of this Lease or otherwise (but only to the extent such
            sum is not reimbursed to Landlord in conjunction with any other
            payment made by Tenant to Landlord), shall have the right to be
            immediately repaid by Tenant the amount of all sums expended by
            Landlord and not repaid by Tenant in connection with preparing or
            improving the Premises to Tenant's specifications and any and all
            costs and expenses incurred in renovating or altering the Premises
            to make it suitable for reletting; and/or

            (iv) As agent of Tenant, do whatever Tenant is obligated to do
            under this Lease, including, but not limited to, lawfully entering
            the Premises, without being liable to prosecution or any claims for
            damages, 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. Landlord shall not be liable for any damages
            resulting to Tenant from such action, unless caused by the
            negligence or willful misconduct of Landlord or otherwise.

           (c) Pursuit by Landlord of any of the foregoing remedies shall not
preclude the pursuit of general or special damages incurred, or of any of the
other remedies provided herein, at law or in equity.

                                     -16-
<PAGE>   20

           (d) No act or thing done by Landlord or Landlord's employees or
agents during the Term shall be deemed an acceptance of a surrender of the
Premises. Neither the mention in this Lease of any particular remedy, nor the
exercise by Landlord of any particular remedy hereunder, at law or in equity,
shall preclude Landlord from any other remedy Landlord might have under this
Lease, at law or in equity. Any waiver of or redress for any violation of any
covenant or condition contained in this Lease or any of the Rules now or
hereafter adopted by Landlord, shall not prevent a subsequent act, which would
have originally constituted a violation, from having all the force and effect
of an original violation. The receipt by Landlord of Rent with knowledge of the
breach of any covenant in this Lease shall not be deemed a waiver of such
breach.

      12. ASSIGNMENT AND SUBLETTING
          -------------------------

           (a) Tenant shall not sublet any part of the Premises, nor assign
this Lease or any interest herein, nor, once any such sublet or assignment is
consented to by Landlord, amend or modify the terms of such sublet or
assignment, without the prior consent of Landlord, which consent shall not be
unreasonably withheld, delayed or conditioned. In no event shall Tenant be
permitted to sublease space or assign its interest in the Lease to any existing
occupant of the Building (whether as a tenant under a lease or otherwise), or
to any subsidiary or affiliate thereof or related party thereto with rent at
below market sublease rates. In any event, no assignee or sublessee other than
one permitted under Section 12(c) below (or Tenant, on behalf or for the
benefit of an assignee or sublessee) shall have the right to exercise any
extension or renewal of Term, or any right to expand or otherwise increase the
size of the Premises. Landlord may deny consent to an assignment or sublease
if, by way of illustration but not limitation, the rate of compensation,
including, but not limited to, all rent, requested by Tenant for the portion of
the Premises to be subleased or for the assignment of the Lease would impact
upon or impair Landlord's ability to rent space in the Building at the then
market rate as offered by Landlord or if the financial statements of the
proposed assignee or sublessee are unsatisfactory. Additionally, neither Tenant
nor any other person having an interest in the possession, use, occupancy or
utilization of the Premises shall enter into any lease, sublease, license,
concession, assignment or other agreement for use, occupancy or utilization of
space in the Premises which provides for rental or other payment for such use,
occupancy or utilization based, in whole or in part, on the net income or
profits derived by any person or entity from the Premises leased, used,
occupied or utilized. Any such purported lease, sublease, license, concession,
assignment or other agreement shall be absolutely void and ineffective as a
conveyance of any right or interest in the possession, use, occupancy or
utilization of any part of the Premises. If such a sublease is entered into,
neither the rental payable thereunder nor the amount thereof passed on to any
person or entity shall have deducted therefrom any expenses or costs related in
any way to the subleasing of such space.

           (b) Consent by Landlord to one assignment or sublease shall not
destroy or waive this provision, and all later assignments and subleases shall
likewise be made only upon prior consent of Landlord, which consent shall not
be unreasonably withheld, delayed or conditioned. If a sublease or assignment
is consented to by Landlord, any sublessees or assignees shall become liable
directly to Landlord for all obligations of Tenant hereunder assumed by such
subtenant or assignee under such sublease or assignment without relieving or in
any way modifying Tenant's liability hereunder. If Tenant notifies Landlord of
Tenant's intent to sublease or assign this Lease, Landlord shall within ten
(10) business days from such notice (a) consent to such proposed subletting;
(b) deny such consent, giving reasons for denying such consent at the time of
the denial; and (c) elect to sublease the space, or take the assignment, as
applicable, on the same terms and conditions as offered by the third-party. If
Landlord gives its consent to any such assignment or sublease, fifty percent
(50%) of any rent or other cost to the assignee or subtenant for all or any
portion of the Premises (net of any reasonable expenses incurred by Tenant in
connection with such sublease or assignment, including without limitation legal
fees, brokerage commissions, concessions payable to such subtenant or assignee
and the cost of any improvements or alterations necessary to effect such
sublease or assignment) over and above the Rent payable by Tenant for such
space shall be due and payable, and shall be paid, to Landlord. If a sublease
or assignment is made as herein provided, Tenant shall pay Landlord a charge
equal to the actual costs incurred by Landlord, in Landlord's reasonable
judgment (including, but not limited to, the use and time of Landlord's
personnel), for all of the necessary legal and accounting

                                     -17-
<PAGE>   21

services required to accomplish such assignment or subletting in an amount not
to exceed $1,000.00 per request.

           (c) Notwithstanding any provision to the contrary, Tenant may assign
this Lease or sublet the Premises without Landlord's consent (i) to any
corporation or other entity that controls, is controlled by or is under common
control with Tenant; (ii) to any corporation or other entity resulting from a
merger, acquisition, consolidation or reorganization of or with Tenant; (iii)
in connection with the sale of all or substantially all of the assets of
Tenant, so long as Tenant provides evidence to Landlord in writing that such
assignment or sublease complies with the criteria set forth in (i), (ii) or
(iii) above and provided such assignee, subtenant or successor-in-interest
expressly assumes Tenants' obligations and liability hereunder and has a net
worth equal to or greater than Tenant had on the date of transfer. No such
assignment, sublease or transfer, however, shall release Tenant form any
covenant, liability or obligation under this Lease.

      13. CONDEMNATION
          ------------

           If the Premises, or a part of such Premises such that the Premises
in the reasonable judgment of the Architect for the Building are untenantable
or Tenant's ability to carry out its normal business operations in the Premises
is materially and adversely impaired, are taken by eminent domain or other
similar proceeding or are conveyed in lieu of such taking, this Lease shall
expire on the date when title or right of possession vests, and Rent paid for
any period beyond said date shall be repaid to Tenant. If there is a partial
taking where this Lease is not terminated, the Rent shall be adjusted in
proportion to the square feet of Premises taken, determined by the Architect
for the Building. In either event, Landlord shall be entitled, and Tenant shall
not have any right, to claim any award made in any condemnation proceeding,
action or ruling relating to the Building or the Property; provided, however,
Tenant shall be entitled to make a claim in any condemnation proceeding, action
or ruling relating to the Building for Tenant's moving expenses and the
unamortized value of leasehold improvements in the Premises actually paid for
by Tenant, to the extent such claim does not in any manner impact upon or
reduce Landlord's claim or award in such condemnation proceeding, action or
ruling. Landlord shall have, in Landlord's sole discretion, the option of
terminating this Lease if any such condemnation, action, ruling or conveyance
in lieu thereof makes continuation of Landlord's use of the Building
economically unfeasible and Landlord closes or demolishes the Building.

      14. INSPECTIONS
          -----------

           Landlord, its agents or employees may enter the Premises upon prior
verbal notice to Tenant (except in the event of an emergency) and at reasonable
hours to (a) exhibit the Premises to prospective purchasers or tenants of the
Premises or the Building but only within the last twelve (12) months of the
Term; (b) inspect the Premises to see that Tenant is complying with its
obligations hereunder; and (c) make repairs (i) required of Landlord under the
terms hereof; (ii) to any adjoining space in the Building; or (iii) to any
systems serving the Building which run through the Premises.

      15. SUBORDINATION
          -------------

           (a) This Lease shall be subject and subordinate to any underlying
land leases or deeds to secure debt which may now or hereafter affect this
Lease, the Building or the Property and also to all renewals, modifications,
extensions, consolidations, and replacements of such underlying land leases and
such deeds to secure debt. This provision shall be self-operative and no
further instrument shall be required to effect such subordination of the Lease.
Notwithstanding the foregoing, if any Mortgagee shall request confirmation of
the subordination set forth in this Paragraph 14, Tenant shall, at Landlord's
request, execute and deliver such further instruments, in a reasonable form, as
may be desired by the holder of the deed to secure debt (a "Mortgagee") or by
any lessor under any such underlying land leases. Notwithstanding the
foregoing, Landlord or such Mortgagee shall have the right to subordinate or
cause to be subordinated, in whole or in part, any such underlying land leases
or deeds to secure debt to this Lease (but not in respect to priority of
entitlement of insurance or condemnation proceeds) on the terms and subject to
the conditions that such Mortgagee deems appropriate in its discretion. If any
such underlying land leases or deeds to secure debt terminate for any reason or
any such

                                     -18-
<PAGE>   22

deeds to secure debt are foreclosed or a conveyance in lieu of foreclosure is
made for any reason, Tenant shall, notwithstanding any subordination, deliver
to Mortgagee within ten (10) business days of written request an attornment
agreement, providing that such Tenant shall continue to abide by and comply
with the terms and conditions of this Lease.

           (b) If any proceedings are brought for the foreclosure of, or in the
event of exercise of the power of sale or conveyance in lieu of foreclosure
under any deed to secure debt, Tenant shall at the option of the purchaser at
such foreclosure or other sale, attorn to such purchaser and recognize such
person as Landlord under this Lease. The institution of any suit, action or
other proceeding by a Mortgagee or a sale of the Property pursuant to the
powers granted to a Mortgagee under its deed to secure debt, shall not, by
operation of law or otherwise, result in the cancellation or the termination of
this Lease or of the obligations of Tenant hereunder.

           (c) If such purchaser requests and accepts such attornment, from and
after such attornment, Tenant shall have the same remedies against such
purchaser for the breach of an agreement contained in this Lease that Tenant
might have had against Landlord if the deed to secure debt had not been
terminated or foreclosed, except such purchaser shall not be (i) liable for any
act or omission of the prior Landlord; (ii) subject to any offsets or defenses
which Tenant might have against the prior Landlord; or (iii) bound by any Rent
or security deposit which Tenant might have paid more than one (1) month in
advance to the prior Landlord.

           (d) Notwithstanding anything to the contrary, in the event a
Mortgagee encumbers the Building or the Premises currently or at any time
following the date of this Lease, Landlord shall obtain from such mortgagee a
signed subordination, non-disturbance and attornment agreement in a form
reasonably satisfactory to Tenant.

      16. INDEMNIFICATION AND HOLD HARMLESS
          ---------------------------------

           (a) Tenant hereby indemnifies and holds Landlord harmless from and
against any injury, expense, damage, liability or claim, imposed on Landlord by
any person whomsoever, whether due to damage to the Premises, claims for
injuries to the person or property of any other tenant of the Building for any
purpose whatsoever, or administrative or criminal action by a governmental
authority, whether such injury, expense, damage, liability or claim results
either directly or indirectly negligence, willful misconduct or breach of any
provisions of this Lease by Tenant, the agents, servants, or employees of
Tenant, or any other person entering upon the Premises under express or implied
invitation or consent of Tenant, and then only to the extent not covered by
Landlord's insurance. Tenant further agrees to reimburse Landlord or Landlord's
property manager for any costs or expenses, including, but not limited to,
court costs and reasonable attorney's fees, which Landlord may incur in
investigating, handling or litigating any such claim or any action by a
governmental authority.

           (b) Tenant shall give prompt notice to Landlord of any materially
defective condition in or about the Premises known to Tenant.

      17. INSURANCE.
          ---------

            (a) Tenant shall carry (at its sole expense during the Term):

            (i) all-risk property insurance, insuring Tenant's interest in its
            improvements to the Premises and any and all furniture, fixtures,
            equipment, supplies, inventory, contents and other property owned,
            leased, held or possessed by Tenant and contained therein, such
            insurance coverage to include business interruption insurance for
            one hundred percent (100%) of Tenant's gross revenues for a period
            of twelve (12) months. Such insurance shall be in an amount equal
            to the full replacement cost of such improvements and property, as
            such may increase from time to time, without deduction for
            depreciation, providing protection against all perils included
            within the classification of fire, extended coverage, vandalism,
            malicious mischief, special extended peril (all risk), boiler and
            machinery, flood, glass breakage and sprinkler leakage, and naming
            Landlord as loss payee as its interest may appear;

                                     -19-
<PAGE>   23

            (ii) worker's compensation insurance as required by applicable law;

            (iii) comprehensive or commercial general liability insurance on an
            occurrence basis 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, and covering Tenant's
            indemnification obligations imposed by Paragraph 15 of this Lease,
            the limits of such policy or policies to be in amounts not less
            than One Million and No/100 Dollars ($1,000,000) in primary
            liability coverage and Five Million and No/100 Dollars ($5,000,000)
            in excess liability coverage; and

            (iv) primary automobile liability insurance with limits of not less
            than One Million and No/100 Dollars ($1,000,000) per occurrence,
            covering owned and non-owned vehicles used by Tenant.

      Landlord retains the right, in its reasonable discretion, to increase the
amount of insurance required to be carried by Tenant not more frequently than
annually based on such factors as inflation, Tenant's insurance claims history,
the advice of Landlord's insurance advisors and any other relevant factors. All
said insurance policies shall be carried with companies licensed to do business
in the State of Georgia reasonably satisfactory to Landlord and shall be
noncancellable except after thirty (30) days written notice to Landlord. Each
policy shall name Landlord and any mortgagee designated by Landlord as
additional insureds and provide that it is primary to, and not contributing
with, any policy carried by Landlord, or other designated person covering the
same loss. Tenant shall deliver duly executed certificates of such insurance to
Landlord prior to the Commencement Date and at least thirty (30) days prior to
the expiration of each respective policy term. No insurance policy or policies
required to be carried by Tenant will be subject to more than a $25,000.00
deductible limit without Landlord's prior written consent. Landlord reserves
the right to require Tenant to carry such other insurance (including, without
limitation and as applicable, plate glass insurance, automobile liability
insurance, builder's risk insurance and liquor liability insurance) and
endorsements customarily required by landlords of tenants similarly situated,
in such amounts as Landlord in its reasonable discretion may deem necessary or
appropriate. If Tenant fails to take out or keep in force any insurance
required to be carried by Tenant, or to provide evidence of the same as
required herein, Landlord shall have the right, but shall not be obligated, to
obtain such insurance at the sole cost and expense of Tenant, and Tenant shall
reimburse Landlord for the cost thereof upon demand as additional Rent.

            (b) During the term of this Lease, Landlord shall carry
comprehensive general liability and casualty insurance with respect to the
Building in amounts generally required by institutional lenders providing
mortgage financing for similar buildings in the area.

            (c) Each of Landlord and Tenant hereby releases the other from any
and all liability or responsibility to the other or anyone claiming through or
under them by way of subrogation or otherwise for any loss or damage to
property caused by fire or any other perils insured in the policies and
insurance covering such property required to be maintained hereunder, even if
such loss or damage shall have been caused by the fault or negligence of the
other party, or anyone for whom such party may be responsible, including any
other tenants or occupants of the remainder of the Building; provided, however,
that this release shall be applicable and in force and effect only to the
extent that such release shall be lawful at the time and in any event only with
respect to loss or damage incurring during such times as the releasing parties'
policies shall contain a clause or endorsement to the effect that any such
release shall not adversely affect or impair said policies or prejudice the
right of the releasing party to recover thereunder and then only to the extent
of the insurance proceeds payable under such policies. Each of Landlord and
Tenant agrees that it will require its insurance carrier to include in its
policies such a clause or endorsement. Failure to obtain such an endorsement
shall not release the waiver contained in this Lease.

      18. REMEDIES CUMULATIVE
          -------------------

            The rights given to Landlord and Tenant herein are in addition to
any rights that may be given to Landlord or Tenant by any statute or under law.

                                     -20-
<PAGE>   24

      19. ENTIRE AGREEMENT - NO WAIVER
          ----------------------------

            This Lease contains the entire agreement of the parties hereto and
no representations, inducements, promises or agreements, oral or otherwise,
between the parties not embodied herein shall be of any force and effect. The
failure of either party to insist in any instance on strict performance of any
covenant or condition hereof, or to exercise any option herein contained, shall
not be construed as a waiver of such covenant, condition or option in any other
instance. This Lease cannot be changed or terminated orally, and can be
modified only in writing, executed by each party hereto.

      20. HOLDING OVER
          ------------

            If Tenant remains in possession of the Premises after expiration of
the Term, or after any termination of the Lease by Landlord, with Landlord's
acquiescence and without any written agreement between the parties, Tenant
shall be a tenant at sufferance and such tenancy shall be subject to all the
provisions hereof, except that the Monthly Rental for said holdover period
shall be one hundred fifty percent (150%) the amount of the Monthly Rental due
in the last month of the Term. There shall be no renewal of this Lease by
operation of law. Neither the acceptance of Rent by Landlord nor anything in
this Paragraph shall be construed as a consent by Landlord to the possession of
the Premises by Tenant after the expiration of the Term or any termination of
the Lease by Landlord, or as an exclusive remedy in the event of a holdover.
With respect to any holdover continuing for more than sixty (60) days following
the expiration of the Lease Term, Tenant shall indemnify Landlord (i) against
all claims for damages by any other tenant to whom Landlord may have leased all
or any part of the Premises effective upon the termination or expiration of
this Lease, and (ii) for all other losses, costs and expenses, including
reasonable attorneys' fees, incurred by reason of such holding over.

      21. HEADINGS
          --------

            The headings in this Lease are included for convenience only and
shall not be taken into consideration in any construction or interpretation of
any part of this Lease.

      22. NOTICES.
          -------

            Any notice, request or consent by either party to the other
hereunder shall be valid only if in writing and shall be deemed to be duly
given only if hand-delivered, or sent by certified mail or by a recognized
national overnight delivery service which has a receipt of notice as a part of
its delivery function. Such notices shall be addressed (i) if to Tenant, at the
Premises, with a copy to Arthur Jay Schwartz, Esq., Smith, Gambrell & Russell,
LLP, Suite 3100, Promenade II, 1230 Peachtree Street, N.E., Atlanta, Georgia
30309, and (ii) if to Landlord, at Landlord's address set forth above, or at
such other address for either party as that party may designate by notice to
the other. Notice shall be deemed given, if delivered personally, upon delivery
thereof, and if mailed, upon the mailing thereof.

      23. HEIRS, SUCCESSORS, AND ASSIGNS - PARTIES
          ----------------------------------------

            (a) This Lease shall bind and inure to the benefit of Landlord and
Tenant, and their respective successors, heirs, legal representatives and
assigns. The term "Landlord" as used in this Lease means only the owner (or the
ground lessee) for the time being of the Property and Building of which the
Premises are a part, so that in the event of any sale or sales of said Property
(or of any lease thereof) whereby such purchaser or lessee assumes in writing
all of Landlord's obligations under this Lease from and after the date of such
sale or lease, Landlord named herein shall be and hereby is entirely released
of all covenants and obligations of Landlord hereunder accruing after such sale
or lease, 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 following such sale or
lease of the Property and Building. If the Property and Building are severed as
to ownership by sale and/or lease, the owner of the entire Building or lessee
of the entire Building that has the right to lease space in the Building to
tenants shall be deemed "Landlord". Tenant shall be bound to any such
succeeding party for performance by Tenant of all the terms, covenants, and
conditions of this Lease and

                                     -21-
<PAGE>   25

agrees to execute any attornment agreement not in conflict with the terms and
provisions of this Lease at the request of any such party.

            (b) The parties "Landlord" and "Tenant" and pronouns relating
thereto, as used herein, shall include male, female, singular and plural,
corporation, partnership or individual, as may fit the particular parties.

      24. ATTORNEY'S FEES
          ---------------

            If Landlord has to engage or consult with an attorney as a result
of or in connection with a failure by Tenant to pay any Rent as and when due
under the Lease, then Tenant shall owe to Landlord, in addition to and not in
lieu of any other amounts due hereunder, and shall pay within ten (10) days
after demand for payment therefor is made, all such reasonable attorneys fees
actually incurred by Landlord. Also, if any law suit or court action between
Landlord and Tenant arises out of or under this Lease, the prevailing party in
such law suit or court action shall be entitled to and shall collect from the
non-prevailing party the reasonable attorney's fees and court costs actually
incurred by the prevailing party with respect to said lawsuit or court action.

      25. TIME OF ESSENCE
          ---------------

            TIME IS OF THE ESSENCE OF THIS LEASE.

      26. NO ESTATE IN LAND
          -----------------

            Tenant has only a usufruct under this Lease, not subject to levy or
sale. No estate shall pass out of Landlord by this Lease.

      27. SECURITY DEPOSIT
          ----------------

            [Intentionally Omitted.]

      28. COMPLETION OF THE PREMISES
          --------------------------

            Landlord shall supervise completion of the work described in
EXHIBIT "C" subject to payments which may be required of Tenant thereunder. Any
work required by Tenant as provided for in said EXHIBIT "C" shall be performed
within the provisions and according to all standards of said EXHIBIT "C".

      29. PARKING ARRANGEMENTS
          --------------------

            Landlord shall maintain 3.25 unreserved parking spaces per 1,000
usable square feet of the Premises for use by Tenant and Tenant's invitees and
employees, as may be modified from time to time, and Tenant (and Tenant's
guests and employees) shall only be entitled to use that amount of parking
spaces (determined on a parking space per square foot leased basis). Such
parking shall be available subject to the reasonable limitations and conditions
from time to time imposed by Landlord; provided, however, that in no event
shall Tenant be required to pay any additional charge with respect to such
parking, it being hereby acknowledged by Landlord and Tenant that any charges
with respect to parking are wholly encompassed by the Monthly Rental payable by
Tenant hereunder. In addition, Tenant shall be entitled to one (1) reserved
space in the Concourse I parking facilities without additional charge. Said
parking shall be maintained on the Property or on areas located in the vicinity
of the Property.

      30. RULES AND REGULATIONS
          ---------------------

            The Rules on EXHIBIT "E" are a part of this Lease. Landlord may
from time to time amend, modify, delete or add additional Rules for the use,
operation, safety, cleanliness and care of the Premises and the Building. Such
new or modified Rules shall be effective upon notice to Tenant. Tenant will
cause its employees and agents, or any others permitted by Tenant to occupy or
enter the Premises to at all times abide by the Rules. If there is a breach of
any Rules, Landlord shall have all remedies in this Lease provided for in an
Event of Default by Tenant and shall, in addition, have any remedies available
at law or in equity, including but not limited to, the right to

                                     -22-
<PAGE>   26

enjoin any breach of such Rules. Landlord shall not be responsible to Tenant
for the nonobservance by any other tenant or person of any such Rules.

      31. RIGHT TO RELOCATE
          -----------------

            If at any time during the Lease Term, the Premises contains less
than 10,000 rentable square feet or if following any sublease or assignment,
Tenant occupies less than 10,000 rentable square feet in the Premises, then, at
any time or from time to time during the Lease Term, Landlord shall have the
unrestricted and unconditional right to relocate Tenant and/or any sublessee
occupying less than 10,000 rentable square feet for the entire remaining term
of this Lease in effect as of the date of such sublease or any assignee
occupying less than 10,000 rentable square feet from the portion of the
Premises so occupied, to any other comparable office space in either the
Building or in that certain building adjacent to the Building and known as
"Concourse Corporate Center II". Landlord shall deliver notice to Tenant of
Landlord's desire to relocate Tenant, together with a proposal for the area to
which such Premises shall be relocated. Should Landlord exercise its right to
relocate Tenant under this Paragraph 30 then (i) all expenses of said
relocation or of any necessary renovation or alteration, necessary to provide
Tenant improvements comparable to those that existed in the original space at
the time of such relocation shall be paid by Landlord, and (ii) following such
relocation, the substituted space shall for all purposes thereinafter
constitute the Premises and all terms and conditions of this Lease shall apply
with full force and effect to the Premises as so relocated. If Tenant has not
relocated its premises within ninety (90) days after Landlord first notifies
Tenant of Landlord's desire to relocate Tenant, then it shall be an event of
default on the part of Tenant, and Landlord shall have, as a part of its
remedies, the right to terminate this Lease. Such termination shall be
effective upon any date selected by Landlord in the Termination Notice which is
at least ten (10) days after the Termination Notice is given by Landlord to
Tenant. In no event shall Tenant incur any costs with respect to the relocation
nor following such relocation pay any Rent in excess of the amounts payable
under this Lease unless the square footage of the Premises was increased in
accordance with Tenant's request. Notwithstanding the foregoing, if the
relocation premises has less rentable square footage than the Premises at the
time of such relocation, Tenant shall be entitled to a proportionate reduction
in Monthly Rental and Tenant's Share, taking into consideration the reduced
rentable square footage of the relocation premises. Tenant hereby further
covenants and agrees to promptly execute and deliver to Landlord any lease
amendment or other such document appropriate to reflect the changes in the
Lease described or contemplated above.

      32. LATE PAYMENTS
          -------------

            Any payment due of Tenant hereunder not received by Landlord within
five (5) business days following Tenant's receipt of written notice from
Landlord of such nonpayment of the date when due shall be assessed a five
percent (5%) charge for Landlord's administrative and other costs in processing
and pursuing the payment of such late payment, and shall be assessed an
additional five percent (5%) charge for the aforesaid costs of Landlord for
each month thereafter until paid in full. Acceptance by Landlord of a payment,
and the cashing of a check, in an amount less than that which is currently due
shall in no way affect Landlord's rights under this Lease and in no way be an
accord and satisfaction. This provision does not prevent Landlord from
declaring the non-payment of Rent when due an event of default hereunder.

      33. ESTOPPEL CERTIFICATE
          --------------------

            Tenant shall, within ten (10) business days of the written request
by Landlord, execute, acknowledge and deliver to Landlord, any Mortgagee,
prospective Mortgagee or any prospective purchaser or transferee of the
Property, the Building, or both (as designated by Landlord), an Estoppel
Certificate in such reasonable, non-recordable form as Landlord may from time
to time require, evidencing to Tenant's actual knowledge whether or not (a)
this Lease is in full force and effect; (b) this Lease has been amended in any
way; (c) Tenant has accepted and is occupying the Premises; (d) there are any

      34. SEVERABILITY AND INTERPRETATION
          -------------------------------

            (a) If any clause or provision of this Lease shall be deemed
illegal, invalid or unenforceable under present or future laws effective during
the Term, the remainder of this Lease shall not be affected by such illegality,
invalidity or unenforceability, and in lieu of each clause or provision of this
Lease that is illegal, invalid or unenforceable, there shall be added as a part
of this Lease a clause or provision as similar in terms to such illegal,
invalid or unenforceable clause or provision as may be possible and be legal,
valid and enforceable.

            (b) If any provisions of this Lease require judicial
interpretation, 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 or the other by reason of the rule of construction
that a document is to be construed most strictly against the party who itself
or through its agent prepared the same, as all parties hereto have participated
in the preparation of this Lease.

      35. MULTIPLE TENANTS
          ----------------

            If more than one individual or entity comprises and constitutes

duties and obligations arising under or in connection with this Lease.

      36. FORCE MAJEURE
          -------------

            Except as otherwise set forth herein, Landlord and Tenant shall be
excused for the period of any delay and shall not be deemed in default with
respect to the performance of any of the terms, covenants, and conditions of
this Lease when prevented from so doing by causes beyond such party's control,
which shall include, but not be limited to, all labor disputes, governmental
regulations or controls, fire or other casualty, inability to obtain any
material or services, or acts of God.

      37. QUIET ENJOYMENT
          ---------------

            So long as Tenant is in full compliance with the terms and
conditions of this Lease, Landlord shall warrant and defend Tenant in the quiet
enjoyment and possession of the Premises during the Term against any and all
claims made by, through or under Landlord, subject to the terms of this Lease.

      38. BROKERAGE COMMISSION; INDEMNITY
          -------------------------------

            HINES PROPERTIES, INC. ("HINES") HAS ACTED AS AGENT FOR LANDLORD IN
THIS TRANSACTION AND JULIEN J. STUDLEY, INC. ("STUDLEY") HAS ACTED AS AGENT FOR
TENANT IN THIS TRANSACTION. BOTH HINES AND STUDLEY ARE TO BE PAID A COMMISSION
BY LANDLORD. Tenant warrants that there are no other claims for broker's
commissions or finder's fees in connection with its execution of this Lease.
Tenant hereby indemnifies Landlord and holds Landlord harmless from and against
all loss, cost, damage or expense, including, but not limited to, attorney's
fees and court costs, incurred by Landlord as a result of or in conjunction
with a claim of any real estate agent or broker, if made by, through or under
Tenant. Landlord hereby indemnifies Tenant and holds Tenant harmless from and
against all loss, cost, damage or expense, including, but not limited to,
attorney's fees and court costs, incurred by Tenant as a result of or in

      39. EXCULPATION OF LANDLORD
          -----------------------

                                     -24-
<PAGE>   28

            Tenant agrees that Tenant shall look solely to Landlord's interest
in the Building, the Property and Landlord's personal property used in
connection therewith ("Landlord's Personal Property") for the satisfaction of
any claim, judgment or decree against Landlord based upon any default hereunder
(a "Tenant Claim"), and no other property or assets of Landlord, its successor
or assigns, or any partner, member, shareholder or other beneficial owner of
any interest in Landlord, or any partner, member, shareholder or other
beneficial owner of any such beneficial owner, shall be subject to the levy,
execution or other enforcement procedure for the satisfaction of any such
Tenant Claim. For purposes of this Section, and subject to the exceptions set
forth below, "interest in the Building, the Property and Landlord's Personal
Property" shall mean, and Tenant may satisfy any Tenant Claim from (i)
Landlord's right, title and interest in the Building, the Property and
Landlord's Personal Property, including net rental income (after deducting all
Operating Costs of the Building including payment of any mortgage) and net
proceeds from a sale received by Landlord after the date Landlord has been
found liable for such Tenant Claim by a court of competent jurisdiction and the
same is not appealable by Landlord ("Claim Date"), (ii) any net insurance or
condemnation proceeds received by Landlord because of damage or condemnation to
or of the Building, the Property and Landlord's Personal Property after the
Claim Date, and (iii) Landlord's right, title and interest in any ground lease,
or master lease or other lease of the Building having Landlord as the tenant
thereunder. Nothing in this Section shall be interpreted to mean that Tenant
cannot be awarded specific performance or injunctive relief. No holder or
beneficiary of any mortgage or deed to secure debt on any part of the Property
shall have any liability to Tenant hereunder for any default of Landlord unless
any written agreement between Tenant and such holder or beneficiary shall
provide otherwise. For the purposes of this paragraph, the "net proceeds" from
a sale or of insurance or condemnation shall mean the gross proceeds received
by Landlord, less in each instance the reasonable costs and expenses
(including, without limitation, attorney's fees and expenses) paid or incurred
in connection with collection of such proceeds, and less any amount applied to
any indebtedness encumbering the Property or Building or (in the case of
insurance or condemnation proceeds) the restoration or repair of the Property,
Building or Premises. If the Property is sold during the pendency of a Tenant
Claim, Tenant shall have the right to look to the new landlord's interest in
the Property as it exists at the time of the judgment. Landlord agrees that as
a condition precedent to the effectiveness of the release in favor of Landlord
set forth above with respect to any Tenant Claim which originates from events
or circumstances occurring prior to a sale or transfer of the Property but
which has not been reduced to judgment prior to such sale or transfer, Landlord
will cause the purchaser or transferee of the Property to assume Landlord's
liability with respect to all obligations and liabilities of Landlord accruing
under the Lease prior to the date of transfer.

      40. ORIGINAL INSTRUMENT
          -------------------

            Any number of counterparts of this Lease may be executed, and each
such counterpart shall be deemed to be an original instrument.

      41. GEORGIA LAW
          -----------

            This Lease has been made under and shall be construed and
interpreted under and in accordance with the laws of the State of Georgia.

      42. NO RECORDATION OF LEASE
          -----------------------

            Without the prior consent of Landlord, neither this Lease nor any
memorandum hereof shall be recorded or placed on public record.

      43. HAZARDOUS MATERIALS
          -------------------

            (a) As used in this Lease, the term "Hazardous Materials" shall
mean and include any substance that is or contains petroleum, asbestos,
polychlorinated biphenyls, lead, or any other substance, material or waste
which is now or is hereafter classified or considered to be hazardous or toxic
under any federal, state or local law, rule, regulation or ordinance relating
to pollution or the protection or regulation of human health, natural resources
or the environment, including without limitation, the Comprehensive
Environmental Response, Compensation and Liability Act of 1980, as amended, 42

and Recovery Act, as amended, 42 U.S.C. Section 6901 et seq., and any
applicable state or local laws and the regulations adopted under these acts

            (b) Tenant shall not (either with or without negligence) cause or
permit the escape, disposal or release of any Hazardous Materials on or in the
Premises, Building or Property. Tenant shall not allow the storage or use of
Hazardous Materials on or in the Premises, Building or Property in any manner
not sanctioned by law or by the highest standards prevailing in the industry
for the storage and use of such Hazardous Materials, nor allow to be brought
into the Building, the Premises or the Property, any such Hazardous Materials
except to use in the ordinary course of Tenant's business, and then only in
compliance with applicable law. 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 regarding the presence of Hazardous
Materials on the Premises. In all events, Tenant shall indemnify Landlord in
the manner elsewhere provided in this Lease from any release of Hazardous
Materials on the Premises occurring while Tenant is in possession, or elsewhere
if caused by Tenant or persons acting under Tenant's control. The within
covenants shall survive the expiration or earlier termination of the Lease
Term.

            (c) Landlord shall comply with all laws relating to Hazardous
Materials.

      44. LEASE BINDING UPON DELIVERY
          ---------------------------

            This Lease shall not be binding until and unless all parties have
duly executed said Lease and a fully executed counterpart of said Lease has
been delivered to Tenant.

      45. SPECIAL STIPULATIONS
          --------------------

            The special stipulations attached hereto as EXHIBIT "F" and made a
part hereof, if any, shall control if in conflict with any of the foregoing
provisions of this Lease.

      46. LANDLORD'S CONSENT
          ------------------

            Unless any consent or approval required of Landlord hereunder is
expressly set forth as subject to Landlord's sole or absolute discretion, such
consent or approval shall not be unreasonably withheld, conditioned or delayed.

5.       Within twenty (20) Working Days after final approval of the Tenant
         Space Plans, Tenant's Architect shall prepare and deliver to Landlord
         the prepared Tenant Improvement Construction Documents.

6.       By the end of the fifth (5th) full Working Day after receipt of the
         Tenant Improvement Construction Documents, Landlord shall review and
         resubmit the same to Tenant's Architect, either with Landlord's consent
         or comments thereto.

7.       By the end of the fifth (5th) full Working Day after receipt of
         Landlord's comments to the Tenant Improvement Construction Documents,
         Tenant's Architect shall resubmit to Landlord the Tenant Improvement
         Construction Documents with such changes or information as requested by
         Landlord.

8        The process described in Section 2.01(5), (6) and (7) shall continue
         until final approval by Landlord and Tenant and such documents shall
         constitute the final Tenant Improvement Construction Documents.

9.       Any approval or consent by Landlord of any items submitted by Tenant
         to and/or reviewed by Landlord pursuant to this Work Letter shall be
         deemed to be strictly limited to an acknowledgment of approval or
         consent by Landlord thereto and shall not imply or be deemed to imply
         any representation or warranty by Landlord that the design is safe or
         structurally sound or will comply with any legal or governmental
         requirements. Any deficiency, mistake or error in design (expressly
         excluding the engineering drawings), although the same has the consent
         or approval of Landlord, shall be the sole responsibility of Tenant,
         and Tenant shall be liable for all costs and expenses which may be
         incurred and all delays suffered in connection with or resulting from
         any such deficiency, mistake or error in design.

Section 3.01  Pricing of Tenant Improvements
--------------------------------------------

(a) Within ten (10) Working Days after final approval of the Tenant Improvement
Construction Documents, Landlord or Tenant (the selection of which shall be at
Tenant's option) shall obtain a price proposal for the Tenant Improvements from
Contractor. Such price proposal shall be subject to Tenant's review and
approval, which approval by Tenant shall not be unreasonably withheld or
delayed. Should Tenant desire to seek adjustments of such price proposal, Tenant
shall work promptly with Tenant's Architect and Contractor to alter the Tenant
Improvement Construction Documents to cause the price quotation to be acceptable
to Tenant and to establish the Tenant Improvement Costs. Upon determination of
the Tenant Improvement Costs and the written approval of the Tenant Improvement
Construction Documents by Tenant, Tenant shall have given final approval of the
same, and Landlord or Tenant, (the selection of which shall be at Tenant's
option) shall be authorized to proceed with contracting with Contractor for the
construction and installation of the Tenant Improvements in accordance with the
Tenant Improvement Construction Documents.

(b) Included in the pricing for the Tenant Improvements shall be the cost of
those Building Standard Materials which Tenant is obligated to purchase under
this Work Letter, which shall be purchased by Tenant in appropriate quantities
for the Premises. The cost of such Building Standard Materials shall be charged
against the Allowance, to the extent available. Landlord shall be entitled to
provide Contractor with Building Standard Materials at Tenant's cost (charged
against the Allowance, to the extent available).

Section 3.02  Construction of Tenant Improvements.
-------------------------------------------------

         Landlord and Tenant shall mutually agree upon whether Landlord or
Tenant shall be responsible for entering into the Construction Contract with
Contractor to construct the Tenant Improvements.

Section 3.03  Tenant Delay
--------------------------

As used herein, the term "Tenant Delay" shall mean delays in the completion of
construction of the Tenant Improvements or other improvements which are caused
by Tenant, its employees, architects, engineers or consultants. The following
are examples of Tenant Delay:

                  A. Tenant's failure to furnish any information or documents
                  in accordance with this Work Letter;

                  B. Failure by Tenant or its employees, architects, engineers,
                  space planners or others employed by Tenant to timely comply
                  with the schedule set forth in Article 2 hereof;

                  C. Any Change Order (including, without limitation, any change
                  in the Tenant Improvement Construction Documents made pursuant
                  to Section 3.01 hereof) resulting in an extension of the
                  estimated date of substantial completion of the improvements,
                  and any failure by Tenant to respond to a "Change Order Effect
                  Notice" (as herein defined) within the time period required
                  hereunder;

                  D. If in the performance or prosecution of Tenant's Work,
                  Tenant's employees or agents interfere with or in any manner
                  hinder Contractor from prosecuting to the fullest extent
                  possible the Tenant Improvements work; or

                  E. Tenant requires any "long-lead time" leasehold improvement
                  item (e.g. millwork) which cannot be fabricated, delivered to
                  the job, and completely installed within the same time frame
                  as the remainder of the Tenant Improvements shown on the
                  Tenant Improvement Construction Documents.

         Landlord shall promptly notify Tenant of the occurrence of any event or
         circumstance which causes, or in Landlord's reasonable judgment will
         cause, a Tenant Delay. For each of such day of Tenant Delay, Landlord
         shall have an additional day to complete the work required hereunder.

Section 3.04  Completion of Premises
------------------------------------

                  A.  Substantial Completion of the Premises shall have
                  occurred, as to any floor, upon the following:

                                    (i) the Tenant Improvements shall have been
                           completed as to the floor, in good and workmanlike
                           order and in substantial compliance with the
                           Construction Contract, except for Punch List Items
                           and otherwise sufficient so that Tenant's Architect
                           can execute the most recently published version of
                           AIA form G704, titled "Certificate of Substantial
                           Completion"; and

                                    (ii) Contractor shall have obtained a
                           certificate of occupancy (or evidence reasonably
                           satisfactory to Landlord and Tenant that upon
                           completion of the Tenant's Work, a certificate of
                           occupancy will be issued) for the Premises in
                           question, permitting occupancy and use of the floor
                           of the Premises in question for the purpose permitted
                           in this Lease;

provided however, that, if and to the extent compliance with any of the
conditions set forth in clauses (i) and (ii) above would have occurred earlier
but for any days of Tenant Delay, then

                                      -4-
<PAGE>   37

compliance with such condition shall be deemed to have occurred on the date it
would have occurred but for the days of Tenant Delay.

Section 3.05  Changes in Plans and Specifications
-------------------------------------------------

                  A. If at any time after the Tenant Improvement Costs are
                  determined, Tenant desires to make Change Orders, Tenant shall
                  submit to Landlord and Contractor for pricing by Contractor
                  working drawings and specifications for any and all such
                  desired Change Order. Contractor shall respond to Tenant, with
                  an estimate of the effect of such desired Change Order on
                  Tenant Improvement Costs and the schedule of anticipated
                  Substantial Completion (the "Change Order Effect Notice").
                  Tenant shall have three (3) Working Days to respond to such
                  Change Order Effect Notice, with the authorization required
                  hereunder, although Tenant may, within said three (3) Working
                  Day period, request more time to finally respond to the Change
                  Order Effect Notice. A failure by Tenant to respond to any
                  such Change Order Effect Notice shall be denial of consent,
                  and, upon denial of a proposed Change Order, Contractor shall
                  proceed with its work in accordance with the Tenant
                  Improvement Construction Documents. Once the cost and the
                  schedule change, if any, for such Change Order has been
                  approved by Tenant, all references in this Work Agreement to
                  the "Tenant Improvement Construction Documents" shall be to
                  the Tenant Improvement Construction Documents, as changed
                  pursuant to this Section 3.05, and all references to "Tenant
                  Improvement Costs" shall include the net aggregate approved
                  cost for the Change Orders determined in this Section 3.05
                  (after taking into account any savings affected by such Change
                  Order).

                  B. Once the Change Order, the costs therefor and the schedule
                  change associated therewith have been approved and a form
                  evidencing such approval executed by Tenant, satisfactory to
                  Landlord, is delivered to Landlord, if applicable, Tenant
                  shall have given full authorization to Landlord to cause
                  Contractor to proceed with the work of constructing the Tenant
                  Improvements in accordance with the Tenant Improvement
                  Construction Documents as so modified; provided that any
                  changes required by Tenant which constitute a material
                  deviation from the previously approved Tenant Improvement
                  Construction Documents shall be effective only after the
                  approval of Landlord, which approval shall not be unreasonably
                  withheld or delayed unless such change would result in a
                  material delay in the completion of the work being done by
                  Contractor.

Section 3.06  General Provisions Applicable to Tenant's Work
------------------------------------------------------------

1.       Landlord will require a high grade, first-class operation to be
         conducted in the Premises. Tenant's Work shall be performed in a
         first-class manner, using new and first-class, quality materials.
         Tenant's Work shall be constructed and installed in accordance with all
         applicable laws, ordinances, codes and rules and regulations of
         governmental authorities. Tenant shall promptly correct any of Tenant's
         Work which is not in conformance therewith.

2.       If Landlord is performing the Tenant Improvements, Landlord shall give
         notice to Tenant of the projected date by which Landlord shall have
         completed the Tenant Improvements on any full floor at least fifteen
         (15) business days prior to said date, and shall provide Tenant with
         access to the Premises for the performance of Tenant's Work and Tenant
         shall proceed forthwith to commence the performance of such work and
         shall diligently pursue such work to completion. Tenant's contract
         parties and subcontractors shall be subject to administrative
         supervisions by Landlord in their use of the Building and their
         relationship with Contractor, or contractors of other tenants in the
         Building. The entry by Tenant and/or its contract parties into the
         Premises for the performance of Tenant's Work shall be subject to all
         of the terms and conditions of the Lease except the payment of Rent.
         If Landlord allows Tenant and/or its contract parties to enter the
         Premises and to commence the performance of Tenant's Work prior to the
         Completion Date, such entry by Tenant shall be at Tenant's sole risk.

3.       Tenant's Work shall be coordinated and conducted to maintain harmonious
         labor relations and not (a) to interfere unreasonably with or to delay
         the completion of any work being per-

                                      -5-
<PAGE>   38

         formed by Contractor or by any other tenant in the Building; or (b) to
         interfere with or disrupt the use and peaceful enjoyment of other
         retail or office tenants in the Building. Contractor shall have
         priority over Tenant's Work.

4.       Tenant and Tenant's contract parties shall perform their work,
         including any storage for construction purposes, within the Premises
         only. Tenant shall be responsible for removal, as needed, from the
         Premises and the Building of all trash, rubbish, and surplus materials
         resulting from any of Tenant's Work being performed in the Premises.
         Tenant shall exercise extreme care and diligence in removing such
         trash, rubbish, or surplus materials from the Premises to avoid
         littering, marring, or damaging any portion of the Building. If any
         such trash, rubbish, or surplus materials are not promptly removed
         from the Building in accordance with the provisions hereof or if any
         portion of the Building is littered, marred, or damaged, Landlord may
         cause same to be removed or repaired, as the case may be, at Tenant's
         cost and expense. If Landlord incurs any costs or expenses in
         performing the above, Tenant shall pay Landlord the amount of any such
         actual cost and expenses promptly upon demand therefor.

         Dollars ($5.00) per rentable square foot of the Premises to be used for
         the excess costs. The Advance shall be disbursed by Landlord to Tenant

                                   -----------

                              SPECIAL STIPULATIONS
                              --------------------

1.       Right of First Offer.
         --------------------

                  (i) Attached hereto as EXHIBIT F-1 is a list of the current
                  anticipated lease expiration dates and size of the respective
                  premises on the seventh (7th) floor of the Building (each of
                  these premises is referred to, individually and collectively,
                  as the "First Offer Space").

                  (ii) Subject to the rights, as of the date of this Lease, of
                  any other tenants in the Building expressly set forth in
                  their leases, prior to execution of a lease for any of the
                  First Offer Space, on or prior to September 1, 2006, and so
                  long as Tenant is not then in default under this Lease,
                  Landlord will notify Tenant of the terms and conditions upon
                  which it would be willing to lease the First Offer Space to
                  Tenant which terms shall include Rent at the same amount then
                  in effect under the Lease.

                  (iii) If within ten (10) business days after receipt of
                  Landlord's notice, Tenant agrees in writing to lease such
                  First Offer Space for a term not to exceed the remaining
                  initial term of this Lease and upon such terms and conditions
                  set forth in Landlord's notice, Landlord and Tenant will
                  execute an amendment to this Lease adding such First Offer
                  Space to the Premises within thirty (30) days after
                  Landlord's receipt of Tenant's notice of intent to lease upon
                  all the same terms as this Lease except as modified by the
                  terms in Landlord's notice. If Tenant does not deliver its
                  notice of intent to lease such First Offer Space or elects
                  not to lease such First Offer Space within such 10-business
                  day period, then this right of first offer to lease such
                  First Offer Space will lapse and be of no further effect and
                  Landlord will have the right to lease such First Offer Space
                  to any third party on the same or any other terms and
                  conditions, whether or not such terms and conditions are more
                  or less favorable than those offered to Tenant; provided,
                  however that the rental rate offered to any third-party shall
                  be no less than 85% of the rental rate offered to Tenant. In
                  addition, if Landlord does not ultimately enter into a lease
                  for such First Offer Space within one (1) year or such space
                  is leased but then again becomes available (following the
                  expiration of any renewal periods granted therein) during the
                  Term of this Lease, such space shall again be subject to
                  Tenant's Right of First Offer hereunder. Landlord agrees that
                  the remaining First Offer Space listed on EXHIBIT F-1 hereto
                  shall remain subject to the terms of this Special Stipulation
                  No. 1.

                  (iv) The right granted to Tenant under this paragraph is
                  personal to Tenant, and in the event of any assignment of
                  this Lease or sublease by Tenant, this right of first offer
                  to lease the First Offer Space shall thenceforth be void and
                  of no further force and effect.

                  (v) In the event Tenant accepts the First Offer Space,
                  Landlord shall provide Tenant with a tenant improvement
                  allowance (the "First Offer Allowance") equal to the original
                  Tenant Improvement Allowance (subject to proration as
                  hereinafter set forth) to be used towards the improvement of
                  the First Offer Space. The amount of the First Offer
                  Allowance shall be prorated for each month of the Term
                  remaining following the commencement of the Lease with
                  respect to the First Offer Space. In other words, the amount
                  of the First Offer Allowance shall be equal to the product of
                  (i) the Tenant Improvement Allowance (expressed on a rentable
                  square foot basis) multiplied by (ii) the rentable square
                  footage in the First Offer Space leased, multiplied by (iii)
                  a fraction, the numerator of which is the number of full
                  months remaining in the initial term of this Lese and the
                  denominator of which is 132.

2.       SIGNAGE. Landlord shall provide, at no cost to Tenant, interior
         building signage in the Building's lobby directory, and building
         standard signage at the entrance to the Premises. Landlord shall also
         provide, at Tenant's cost, but subject to reimbursement out of the
         Allowance to the extent available, a building standard panel on the
         pylon sign located in front of the Building which is currently utilized
         exclusively by Xerox. Tenant's right to signage hereunder shall be
         non-exclusive.

3.       RENEWAL OPTION. So long as this Lease is in full force and effect and
         Tenant is not in default hereunder, Tenant shall have the option (the
         "Extension Option") to extend the Term for the entire Premises for two
         (2) additional period of five (5) years (the "Extension Periods" and,
         individually, an "Extension Period") subject to the following terms and
         conditions:

         a.       Tenant shall not have the right to assign the Extension Option
                  to any sublessee or assignee of the Premises other than to a
                  permitted transferee under Section 12(c) of the Lease, nor may
                  such sublessee or assignee exercise or enjoy the benefit of
                  such Extension Option.

         b.       Tenant shall have given Landlord written notice of its
                  exercise of the Extension Option on or before twelve (12)
                  months prior to the expiration of the Term.

         c.       The Extension Option shall be only applicable to the entire
                  Premises, as it may have expanded or contracted from time to
                  time pursuant to the terms of this Lease.

         d.       The terms and conditions of this Lease, as it may have been
                  amended from time to time, shall remain in full force and
                  effect during any Extension Period except that the term "Base
                  Rent" shall be modified to mean the rent charged at the
                  Prevailing Market Rate (as hereinafter defined).

         e.       "Prevailing Market Rate" shall mean the then prevailing
                  market rate for rent for leases in similar quality buildings
                  in the market for space comparable to the Premises taking
                  into account such factors offered to third party tenants for
                  comparable space, including, without limitation, as the base
                  services year for pass-through expenses, rent and other
                  concessions, tenant improvement allowances, lease commissions
                  saved or incurred, and moving allowances. If Landlord and
                  Tenant cannot agree in writing on the Prevailing Market Rate
                  within thirty (30) days after Tenant's notice of its election
                  to renew, the Prevailing Market Rate shall be determined by
                  the Three Broker Method set forth below. Tenant shall have no
                  option to renew this Lease beyond the expiration of the
                  second Renewal Term, and the Premises shall be delivered in
                  their existing condition (on an "as is" basis) at the time
                  each Renewal Term commences.

                  The "Three Broker Method" shall operate as follows: The
                  Prevailing Market Rate shall be based upon the current fair
                  market rental rate for comparable space in comparable
                  buildings in the Atlanta, GA "perimeter" area, (taking into
                  account concessions which are being offered in the
                  marketplace) which shall be determined by a board of three (3)
                  licensed real estate brokers, one of whom shall be named by
                  Landlord, one by Tenant, and the two so appointed shall select
                  a third broker. Each member of the board of brokers shall be
                  licensed in Georgia as a real estate broker, specializing in
                  the field of commercial office leasing in the Atlanta, Georgia
                  area, having no less than ten (10) years' experience in such
                  field, and recognized as ethical and reputable within the
                  field. Landlord and Tenant agree to make their appointments
                  within five (5) days after Landlord and Tenant are unable to
                  agree upon the Prevailing Market Rate. The two (2) brokers
                  selected by Landlord and Tenant shall select the third broker
                  within ten (10) days after they both have been appointed, and
                  each broker, within fifteen (15) days after the third broker
                  is elected, shall submit his or her determination of the
                  Prevailing Market Rate. The Prevailing Market Rate shall be
                  the determination of the broker that is not the highest or the
                  lowest (or, if two brokers reach an identical determination,
                  the determination of such two brokers). Landlord and Tenant
                  shall each pay the fee of the broker selected by it, and they
                  shall equally share the payment of the fee of the third
                  broker.

         f.       Within ten (10) business days following the determination of
                  the "Prevailing Market Rate" pursuant to the "Three Broker
                  Method" described in subsection e above, Tenant shall have the
                  right to revoke its exercise of its renewal option by written
                  notice to Landlord; in which event this Lease shall expire as
                  if such renewal option had never been exercised by Tenant.

         g.       Within ten (10) days after the establishment of the Prevailing
                  Market Rate provided Tenant has not revoked its exercise of
                  its renewal option as aforesaid, Landlord and Tenant agree to
                  enter into active and good faith negotiation of an amendment
                  to this Lease to evidence the exercise of the Extension
                  Option.

4.  SUBLEASE. Landlord acknowledges that Tenant is currently subleasing Suite
770 from Valinor, Inc. pursuant to a Sublease Agreement dated March 30, 1999
(the "Sublease"). If (a) Tenant occupies Suite 800 pursuant to this Lease prior
to the expiration of the term of the Sublease and (b) Tenant no longer occupies
Suite 770, Landlord shall, effective on the later to occur of (a) and (b)
above, either assume Tenant's obligations under the Sublease or cause Valinor,
Inc. to terminate the Sublease so that Tenant shall have no obligations
thereunder as of the effective date of such assumption or termination.

5.  EXPANSION RIGHT. So long as Tenant is not in default hereunder, Tenant shall
have the right (the "Expansion Option") to lease the Expansion Space (as that
term is hereinafter defined) at any time or from time to time during the Term
of this Lease pursuant to and in accordance with the following terms and
conditions:

         a.       The Expansion Space shall mean, individually or collectively,
                  Suites 750, 760 and 780 in the Building.

         b.       Tenant shall provide Landlord with six (6) months prior
                  notice of its election to exercise the Expansion Option.
                  Should Tenant exercise the Expansion Option, the Expansion
                  Space shall be added to this Lease from and after the date
                  Landlord delivers the Expansion Space to Tenant, or such
                  earlier date to which Landlord and Tenant may mutually agree,
                  through the last day of the Term, as the same may be
                  extended. The Expansion Space shall be subject to all terms
                  and provisions of this Lease, including Base Rent (on a per
                  square foot basis), and Additional Rent then in effect for
                  the Premises.

         c.       Landlord shall provide to Tenant a tenant improvement
                  allowance for the Expansion Space in an amount equal to the
                  product of the Tenant Improvement Allowance (on a rentable
                  square foot basis) times the rentable square footage of the
                  Expansion Space times a fraction, the numerator of which is
                  the number of full calendar months remaining in the initial
                  Term of the Lease and the denominator of which is 132.

         d.       If the Expansion Space is currently occupied, Landlord shall
                  relocate the tenant pursuant to the terms of its lease. In
                  the event Landlord must relocate any tenant within the
                  affected Expansion Space, Tenant agrees to pay all reasonable
                  relocation costs incurred by Landlord in relocating such
                  tenant, including restoration or improvements costs for the
                  relocated space of such tenant. Landlord will inform Tenant
                  of Landlord's reasonable estimate of the proposed relocation
                  costs prior to effecting the relocation and Tenant shall have
                  the opportunity to revoke its exercise of the Expansion
                  Option by notice to Landlord within ten (10) days of Tenant's
                  receipt of the aforesaid relocation costs estimate.

         e.       Notwithstanding anything to the contrary, Tenant's Expansion
                  Option shall be subject to the rights of any existing tenants
                  in any of the Expansion Space (including any renewal rights
                  thereunder).

         Landlord hereby agrees that it shall include a relocation provision in
each new lease entered into for any portion of the Expansion Space.

                                      -3-

6.  EARLY TERMINATION RIGHT. Notwithstanding anything to the contrary contained
in this Lease, provided Tenant is not in default hereunder, Tenant shall have
the option to terminate this Lease, effective on the last day of the eight (8th)
Lease Year, the last day of the ninth (9th) Lease Year, or the last day of the
tenth (10th) Lease Year (the "Termination Dates") by providing Landlord with
written notice of such Termination Option election (the "Termination Notice").
Such Termination Notice shall be effective only if it is given to Landlord at
least twelve (12) months prior to the respective Termination Date (the
"Termination Notice Deadline"); accordingly, if Tenant has not given its
Termination Notice to Landlord prior to the Termination Notice Deadline with
respect to such Termination Date, the Termination Option with respect to said
Termination Date shall expire and be of no further force or effect. Tenant shall
have no right or option to terminate this Lease pursuant to this paragraph at
any time after the Last Termination Notice Deadline. As a condition precedent to
any termination of this Lease pursuant to the provisions of this paragraph,
Tenant shall pay to Landlord an amount as a termination fee equal to one hundred
percent (100%) of the unamortized portion (amortized at eleven percent (11%) per
annum) of the tenant improvement allowance which includes twenty five dollars
($25.00) per rentable square plus the cost of repairing the ceiling. The
termination fee shall be paid no later than sixty (60) days prior to the end of
this Lease. It is hereby acknowledged that any such amount required to be paid
by Tenant in connection with such early termination is not a penalty but a
reasonable pre-estimate of the damages which would be incurred by Landlord as a
result of such early termination of this Lease (which damages are impossible to
calculate more precisely) and, in that regard, constitutes liquidated damages
with respect to such loss. Tenant shall continue to be liable for its
obligations under this Lease to and through the Termination Date including,
without limitation, additional rental that accrues pursuant to the terms of this
Lease, with all of such obligations surviving the early termination of this
Lease. The rights granted to Tenant under this paragraph are personal to Tenant,
and in the event of any assignment of this Lease or sublease by Tenant, this
Termination Option shall thenceforth be void and of no further force or effect.

                  Letter shall be deemed to be strictly limited to an
                  acknowledgment of approval or consent by Landlord thereto and
                  shall not imply or be deemed to imply any representation or
                  warranty by Landlord that the design is safe or structurally
                  sound or will comply with any legal or governmental
                  requirements. Any deficiency, mistake or error in design
                  (expressly excluding the engineering drawings), although the

                  sole responsibility of Tenant, and Tenant shall be liable for
                  all costs and expenses which may be incurred and all delays
                  suffered in connection with or resulting from any such
                  deficiency, mistake or error in design."
