electrical, plumbing or HVAC equipment through the areas behind the walls, below
the floors or above the drop ceilings; and (e) to exercise any other right or
perform any other obligation that Landlord has under this Lease.  Landlord shall
be allowed to take all material into and upon the Premises that may be required
to make any repairs, improvements and additions, or any alterations, without in
any way being deemed or held guilty of trespass and without constituting a
constructive eviction of Tenant.  The Rent reserved herein shall not abate while
said repairs, alterations or additions are being made and Tenant shall not be
entitled to maintain a set-off or counterclaim for damages against Landlord by
reason of loss from interruption to the business of Tenant because of the
prosecution of any such work.  All such repairs, decorations, additions and
improvements shall be done during ordinary business hours, or, if any such work
is at the request of Tenant to be done during any other hours, the Tenant shall
pay all overtime and other extra costs.

     20.  Services.

lavatories;

                    (iv)   Soap, paper towels, and toilet tissue for public
restrooms;

                    (v)    Janitorial service during normal business hours

generally maintained in similar office buildings in the Atlanta, Georgia,
metropolitan area;

                    (vi)   Custodial, electrical and mechanical maintenance
services during normal business hours;

                    (vii)  Electric power for lighting and outlets not in excess

connected load;

                    (viii) Replacement of Building standard lamps and ballasts
as needed during normal business hours;

                    (ix)   Repairs and maintenance as described in Section 10 of
this Lease during normal business hours;

                    (x)    General management, including supervision,
inspections, recordkeeping, accounting, leasing and related management functions
during normal business hours;

                    (xi)   Mail delivery during normal business hours through
the common mailroom located in the Building in the manner currently provided;
provided, however, that notwithstanding the "full service" nature of this Lease
or any provisions hereof to the contrary, the reasonable and actual cost of
labor and supplies associated with the operation of said mailroom (including all
operating expenses except postage) shall be divided between Landlord and Tenant
on a 60/40 basis (i.e., Tenant shall be responsible for 40% of such cost), and
Tenant's postage (including courier, express mail and the like) shall be
separately metered. Tenant shall be billed by Landlord monthly for such postage
and such share of other costs, with payment due from Tenant to Landlord within
ten (10) days of receipt of each such monthly invoice (which invoices shall be
accompanied by copies of supporting documentation evidencing Tenant's postage),
and such amounts due from Tenant shall constitute Additional Rent hereunder.
Notwithstanding the foregoing, Landlord and Tenant agree to cooperate in good
faith to reapportion the allocation of such operating expenses at the beginning
of each fiscal year of Landlord's during the Term based on volume of Tenant's
usage during the immediately preceding fiscal year (or portion thereof); and

                    (xii)  Security guard service during normal business hours
substantially in the manner currently provided.

          (b)  Tenant shall have no right to any services in excess of those
provided herein.  If Tenant uses services in an amount or for a period in excess
of that provided for herein, then Landlord reserves the right to:  charge Tenant
as Additional Rent hereunder a reasonable sum as reimbursement for the direct
and actual cost of such added services; and/or charge Tenant for the cost of any
additional equipment or facilities or modifications thereto, necessary to
provide the additional services.

                                      -6-
<PAGE>

          (c)  Landlord shall not be liable for any damages directly or
indirectly resulting from the interruption in any of the services described
above unless and to the extent resulting from the negligence or willful
misconduct of Landlord or its agents, employees or contractors, nor shall any
such interruption entitle Tenant to any abatement of Rent except as expressly
set forth herein, or any right to terminate this Lease.  Landlord shall use all
reasonable efforts to furnish uninterrupted services as required above.
Notwithstanding anything to the contrary contained herein, if Tenant cannot
reasonably use (and actually ceases to use) all or any material portion of the
Premises for Tenant's intended business operations by reason of any interruption
in services to be provided by Landlord as a result of the acts or omissions of
Landlord, its agents or employees, and such interruption continues for five (5)
or more consecutive business days, then Base Rent due under this Lease shall be
abated starting with the day immediately succeeding such five (5) business day
period for that portion of the Premises that Tenant is unable (and actually
ceases) to use for Tenant's intended business operations until such services are
restored to the Premises.  Tenant shall not be entitled to the rent abatement
right set forth above if the service interruption is caused by the act or
omission of Tenant, its agents or employees.

     21.  Indemnities.  Tenant does hereby indemnify and save harmless Landlord
          ------------
against all claims for damages to persons or property anywhere in the Building
or on the Property to the extent caused by the negligence or willful misconduct
of Tenant, its agents or employees or which occur in the Premises (or arise out
of actions taking place in the Premises) except to the extent such damage is
caused by the negligence or willful misconduct of Landlord, its agents or
employees.  Landlord does hereby indemnify and hold Tenant harmless against all
claims for damaged persons or property to the extent caused by the negligence or
willful misconduct of Landlord, its agents or employees.  The indemnities set
forth hereinabove shall include the application to pay reasonable expenses
actually incurred by the indemnified party, including, without limitation,
reasonable, actually incurred attorneys' fees.  The indemnities contained herein
do not override the waivers contained in Section 22(e) below.

     22.  Tenant's Insurance; Waivers.
          ----------------------------

          (a)  Tenant further covenants and agrees that from and after the date
of delivery of the Premises from Landlord to Tenant, Tenant will carry and
maintain, at its sole cost and expense, the following types of insurance, in the
amounts specified and in the form hereinafter provided for:

               (i)  Liability Insurance in the Commercial General Liability form
(or reasonable equivalent thereto) covering the Premises and Tenant's use
thereof against claims for personal injury or death, property damage and product
liability occurring upon, in or about the Premises, such insurance to be written
on an occurrence basis (not a claims made basis), to be in combined single
limits amounts not less than $3,000,000 and to have general aggregate limits of
not less than $5,000,000 for each policy year. The insurance coverage required
under this Section 22(a)(i) shall, in addition, extend to any liability of
Tenant arising out of the indemnities provided for in Section 21 and, if
necessary, the policy shall contain a contractual endorsement to that effect.
The general aggregate limits under the Commercial General Liability insurance
policy or policies must apply separately to the Premises and to Tenant's use
thereof (and not to any other location or use of Tenant) and such policy shall
contain an endorsement to that effect. The certificate of insurance evidencing
the Commercial General Liability form of policy shall specify all endorsements
required herein and shall specify on the face thereof that the limits of such
policy applies separately to the Premises.

                                      -7-
<PAGE>

               (ii)   Insurance covering all trade fixtures, merchandise and
personal property from time to time in, on or upon the Premises, and
alterations, additions or changes made by Tenant pursuant to Section 10, in an
amount not less than one hundred percent (100%) of their full replacement value
from time to time during the Term, providing protection against perils included
within the standard form of "all-risks" fire and casualty insurance policy,
together with insurance against sprinkler damage, vandalism and malicious
mischief. Any policy proceeds from such insurance shall be held in trust by
Tenant's insurance company for the repair, construction and restoration or
replacement of the property damaged or destroyed (and shall be released to the
party who is required to restore the damaged property in question pursuant to
the terms hereof, and if no such party is so designated herein, then to Tenant)
unless this Lease shall cease and terminate under the provisions of Section 28
of this Lease (in which case they will be distributed to Landlord to the extent
allocable to damage to improvements or alterations made to the Premises, and to
Tenant to the extent allocable to damage to Tenant's trade fixtures, merchandise
and personal property).

               (iii)  Workers' Compensation and Employer's Liability insurance
affording statutory coverage and containing statutory limits with the Employer's
Liability portion thereof to have minimum limits of $100,000.00.

               (iv)   Business Interruption Insurance equal to not less than
fifty percent (50%) of the estimated gross earnings (as defined in the standard
form of business interruption insurance policy) of Tenant at the Premises which
insurance shall be issued on an "all risks" basis (or its equivalent).

          (b)  All policies of the insurance provided for in Section 22(a) shall
be issued in form acceptable to Landlord by insurance companies with a rating
and financial size of not less than A-X in the most current available "Best's
Insurance Reports", and licensed to do business in the state in which Landlord's
Building is located.  Each and every such policy:

               (i)    shall, with respect to the commercial general liability
insurance required above, name Landlord (as well as any mortgagee of Landlord
and any other party reasonably designated by Landlord) as an additional insured.

               (ii)   shall be delivered to each of Landlord and any such other
parties in interest within thirty (30) days after delivery of possession of the
Premises to Tenant and thereafter within thirty (30) days prior to the
expiration of each such policy, and, as often as any such policy shall expire or
terminate. Renewal or additional policies shall be procured and maintained by
Tenant in like manner and to like extent;

               (iii)  shall contain a provision that the insurer will give to
Landlord and such other parties in interest at least thirty (30) days notice in
writing in advance of any material change, cancellation, termination or lapse,
or the effective date of any reduction in the amounts of insurance; and

               (iv)   shall be written as a primary policy which does not
contribute to and is not in excess of coverage which Landlord may carry.

          (c)  Any insurance provided for in Section 22(a) may be maintained by
means of a policy or policies of blanket insurance, covering additional items or
locations or insureds, provided, however, that:

                                      -8-
<PAGE>

               (i)    with respect to the commercial general liability insurance
required above, Landlord and any other parties in interest from time to time
designated by Landlord to Tenant shall be named as an additional insured
thereunder as its interest may appear;

               (ii)   the coverage afforded Landlord and any such other parties
in interest will not be reduced or diminished by reason of the use of such
blanket policy of insurance;

               (iii)  any such policy or policies [except any covering the risks
referred to in Section 22(a)(i)] shall specify therein (or Tenant shall furnish
Landlord with a written statement from the insurers under such policy
specifying) the amount of the total insurance allocated to the Tenant's
improvements and property more specifically detailed in Section 22(a); and

               (iv)   the requirements set forth in this Section 22 are
otherwise satisfied.

          (d)  Landlord shall maintain at all times during the Term of this
Lease, with such deductible as Landlord in its sole judgment determines
advisable, insurance on the "All-Risk" or equivalent form on a Replacement Cost
Basis against loss or damage to the Building.  Such insurance shall be in the
amount of 80% of the replacement value of the Building (excluding all fixtures
and property required to be insured by Tenant under this Lease).    Landlord
shall also maintain at all times during the Term commercial general liability
insurance with limits at least equal to the amount as Tenant is required to
maintain pursuant to Section 22(a)(i) of this Lease.

          (e)  Notwithstanding anything to the contrary set forth hereinabove,
Landlord and Tenant do hereby waive any and all claims against one another for
damage to or destruction of real or personal property to the extent such damage
or destruction can be covered by "all risks" property insurance of the types
described above.  Each party shall also be responsible for the payment of any
deductible amounts required to be paid under the applicable "all risks" fire and
casualty insurance carried by the party whose property is damaged.  These
waivers shall apply if the damage would have been covered by a customary "all
risks" insurance policy, even if the party fails to obtain such coverage.  The
intent of this provision is that each party shall look solely to its insurance
with respect to property damage or destruction which can be covered by "all
risks" insurance of the types described above.

     23.  Governmental Requirements.  Tenant shall, at its own expense, promptly
          -------------------------
comply with all requirements of any legally constituted governmental or public
authority made necessary by reason of any unique use by Tenant of the Premises
(as opposed to office and administrative uses generally), including, without
limitation, the Americans with Disabilities Act (the "ADA"). Landlord shall
otherwise cause the Buildings and Common Area to be in compliance with all
applicable laws, regulations and ordinances, including the ADA.

     24.  Intentionally Omitted.
          ---------------------

     25.  Assignment and Subletting.  Tenant may not, without the prior written
          -------------------------
consent of Landlord, which consent may be withheld by Landlord in its sole,
unfettered discretion, assign this Lease or any interest hereunder, or sublet
the Premises or any part thereof, or permit the use of the Premises by any party
other than Tenant.  In the event that Tenant is a corporation or entity other
than an individual, any transfer of a majority or controlling interest in Tenant
(whether by stock transfer, merger, operation of law or otherwise) shall be
considered an assignment for

                                      -9-
<PAGE>

purposes of this paragraph and shall require Landlord's prior written consent.
Consent to one assignment or sublease shall not destroy or waive this provision,
and all later assignments and subleases shall likewise be made only upon the
prior written consent of Landlord. Subtenants or assignees shall become liable
to Landlord for all obligations of Tenant hereunder, without relieving Tenant's
liability hereunder and, in the event of any default by Tenant under this Lease,
Landlord may, at its option, but without any obligation to do so, elect to treat
such sublease or assignment as a direct Lease with Landlord and collect rent
directly from the subtenant. In addition, upon any request by Tenant for
Landlord's consent to an assignment or sublease, Landlord may elect to terminate
this Lease and recapture all of the Premises (in the event of an assignment
request) or the applicable portion of the Premises (in the event of a subleasing
request); provided, however, if Landlord notifies Tenant that Landlord elects to
exercise this recapture right, Tenant may, within five (5) business days of its
receipt of Landlord's notice, notify Landlord that Tenant withdraws its request
to sublease or assign, in which case Tenant shall continue to lease all of the
Premises, subject to the terms of this Lease and Landlord's recapture notice
shall be null and void. If Tenant desires to assign or sublease, Tenant must
provide written notice to Landlord describing the proposed transaction in detail
and providing all documentation (including detailed financial information for
the proposed assignee or subtenant) reasonably necessary to let Landlord
evaluate the proposed transaction. Landlord shall notify Tenant within thirty
(30) days of its receipt of such notice whether Landlord elects to exercise its
recapture right and, if not, whether Landlord consents to the requested
assignment or sublease. If Landlord fails to respond within such thirty (30) day
period, Landlord will be deemed not to have elected to recapture and not to have
consented to the assignment or sublease. If Landlord does consent to any
assignment or sublease request and the assignee or subtenant pays to Tenant an
amount in excess of the Rent due under this Lease (after deducting Tenant's
reasonable, actual expenses in obtaining such assignment or sublease), Tenant
shall pay 50% of such excess to Landlord as and when the monthly payments are
received by Tenant. Notwithstanding anything to the contrary contained in this
Section 25, Tenant may assign or sublet its rights and obligations under this
Lease without Landlord's prior consent to a successor corporation into which or
with which Tenant is merged or consolidated or which acquired all or
substantially all of Tenant's assets and property, provided that such successor
corporation assumes substantially all of the obligations and liabilities of
Tenant hereunder.

     26.  Tenant Default/Landlord Remedies.
          --------------------------------

     (a)  Tenant Default.  If Tenant shall default in the payment of Rent herein
          --------------
reserved when due and fails to cure such default within five (5) business days
after written notice of such default is given to Tenant by Landlord; or if
Tenant shall be in default in performing any of the terms or provisions of this
Lease other than the provisions requiring the payment of Rent, and fails to cure
such default within thirty (30) days after written notice of such default is
given to Tenant by Landlord or, if such default cannot be cured within thirty
(30) days, Tenant shall not be in default if Tenant promptly commences and
diligently proceeds the cure to completion as soon as possible and in all events
within sixty (60) days; or if Tenant is adjudicated a bankrupt; or if a
permanent receiver is appointed for Tenant's Property and such receiver is not
removed within ninety (90) days after written notice from Landlord to Tenant to
obtain such removal; or if, whether voluntarily or involuntarily, Tenant takes
advantage of any debtor relief proceedings under any present or future law,
whereby the Rent or any part thereof, is, or is proposed to be, reduced or
payment thereof deferred; or if Tenant's effects should be levied  upon or
attached and such levy or attachment is not satisfied or dissolved within thirty
(30) days after written notice from Landlord to Tenant to obtain satisfaction
thereof; then, and in any of said events, Landlord, at its option, may exercise
any or all of the remedies set forth in Section 26(b) below.

                                      -10-
<PAGE>

     (b)  Landlord Remedies.  Upon the occurrence of any default set forth in
          -----------------
Section 26 above which is not cured by Tenant within the applicable cure period
provided therein, if any, Landlord may exercise all or any of the following
remedies:

          (i)   terminate this Lease by giving Tenant written notice of
termination, in which event this Lease shall terminate on the date specified in
such notice and all rights of Tenant under this Lease shall expire and terminate
as of such date, Tenant shall remain liable for all obligations under this Lease
up to the date of such termination and Tenant shall surrender the Premises to
Landlord on the date specified in such notice, and if Tenant fails to so
surrender, Landlord shall have the right, without notice, to enter upon and take
possession of the Premises and to expel and remove Tenant and its effects
without being liable for prosecution or any claim of damages therefor;

          (ii)  terminate this Lease as provided in the immediately preceding
subsection and recover from Tenant all damages Landlord may incur by reason of
Tenant's default, including without limitation, the then present value of (1)
the total Rent which would have been payable hereunder by Tenant for the period
beginning with the day following the date of such termination and ending with
the Expiration Date of the term as originally scheduled hereunder, minus (2) the
aggregate reasonable rental value of the Premises for the same period (as
determined by a real estate broker licensed in the State of Georgia, who has at
least ten (10) years experience, immediately prior to the date in question
evaluating commercial office space, taking into account all relevant factors
including, without limitation, the length of the remaining Term, the then
current market conditions in the general area, the likelihood of reletting for a
period equal to the remainder of the Term, net effective rates then being
obtained by landlords for similar type space in similar buildings in the general
area, vacancy levels in the general area, current levels of new construction in
the general area and how that would affect vacancy and rental rates during the
period equal to the remainder of the Term and inflation), plus (3) the costs of
recovering the Premises, and all other expenses incurred by Landlord due to
Tenant's default, including, without limitation, reasonable attorneys' fees
actually incurred, plus (4) the unpaid Rent earned as of the date of
termination, plus interest, all of which sum shall be immediately due and
payable by Tenant to Landlord;

          (iii) without terminating this Lease, and without notice to Tenant,
Landlord may in its own name, but as agent for Tenant enter into and take
possession of the Premises and re-let the Premises, or a portion thereof, as
agent of Tenant, upon any terms and conditions as Landlord may deem necessary or
desirable (Landlord shall have no obligation to attempt to re-let the Premises
or any part thereof). Upon any such re-letting, all rentals received by Landlord
from such re-letting shall be applied first to the costs incurred by Landlord in
accomplishing any such re-letting, and thereafter shall be applied to the Rent
owed by Tenant to Landlord during the remainder of the term of this Lease and
Tenant shall pay any deficiency between the remaining Rent due hereunder and the
amount received by such re-letting as and when due hereunder;

          (iv)  allow the Premises to remain unoccupied and collect Rent from
Tenant as it becomes due; or

          (v)   pursue such other remedies as are available at law or in equity.

     27.  Landlord Default/Tenant Remedies. Landlord shall not be in default
          --------------------------------
unless it fails to perform the obligations required of it by this Lease within
thirty (30) days after written notice from Tenant specifying which obligation
Landlord has failed to perform; provided, however, that if the nature of the
specified obligation is such that more than thirty (30) days are

                                      -11-
<PAGE>

reasonably required to complete its cure, then Landlord shall not be in default
if it commences to cure within said thirty (30) day period and thereafter
diligently prosecutes the same to completion. As to Landlord's maintenance and
repair obligations hereunder, if Landlord has not cured or commenced to cure a
maintenance or repair default set forth in said notice within said thirty (30)
day period, Tenant, may, at its option, cure such default. If Tenant elects to
cure said default, Tenant shall, prior to commencement of said work, provide to
Landlord a specific description of the work to be performed by Tenant and the
name of Tenant's contractor. Any materials used shall be of equal or better
quality than currently exists in the Building and Tenant's contractor shall be
adequately insured and of good reputation. Landlord shall reimburse Tenant for
the reasonable, actual cost of said cure upon receipt of adequate bills or other
supporting evidence substantiating said cost, less any amounts otherwise
reimbursable to Tenant under any insurance policies carried by Tenant.

     28.  Destruction or Damage.
          ---------------------

          (a) If the Building or the Premises are totally destroyed by storm,
fire, earthquake, or other casualty, or damaged to the extent that, in
Landlord's reasonable opinion the damage cannot be restored within one hundred
eighty (180) days of the date Landlord provides Tenant written notice of
Landlord's reasonable estimate of the time necessary to restore the damage, or
if the damage is not covered by standard "all risks" property insurance and as a
result Landlord elects not to restore such damage, Landlord or Tenant shall have
the right to terminate this Lease effective as of the date of such destruction
or damage by written notice to the other on or before thirty (30) days following
Landlord's notice described in the next sentence and Rent shall be accounted for
as between Landlord and Tenant as of that date.  Landlord shall provide Tenant
with notice within forty-five (45) days following the date of the damage of the
estimated time needed to restore, and whether the loss is covered by Landlord's
insurance coverage (and if not, whether Landlord nevertheless elects to
restore).

          (b) If the Premises are damaged by any such casualty or casualties but
neither party is entitled to or neither party elects to terminate this Lease as
provided in subparagraph (a) above, this Lease shall remain in full force and
effect, Landlord shall notify Tenant in writing within forty-five (45) days of
the date of the damage that the damage will be restored (and will include
Landlord's good faith estimate of the date the restoration will be complete), in
which case Rent shall abate as to any portion of the Premises which is not
usable, and Landlord shall restore the Premises to substantially the same
condition as before the damage occurred as soon as practicable, whereupon full
Rent shall recommence.

     29.  Eminent Domain.  If the whole of the Building or Premises, or such
          --------------
portion thereof as will make the Building or Premises unusable in the reasonable
judgment of Landlord and Tenant, cooperating together reasonably and in good
faith, for their intended purposes, is condemned or taken by any legally
constituted authority for any public use or purpose, then in either of said
events, Landlord or Tenant may terminate this Lease by written notice to the
other and the Term hereby granted shall cease from that time when possession
thereof is taken by the condemning authorities, and Rent shall be accounted for
as between Landlord and Tenant as of that date.  If a portion of the Building or
Premises is so taken, but not such amount as will make the Premises unusable in
the reasonable judgment of Landlord and Tenant, cooperating together reasonably
and in good faith, for the purposes herein leased, or if neither Landlord nor
Tenant elect to terminate this Lease as aforesaid, this Lease shall continue in
full force and effect and the Rent shall be reduced prorata in proportion to the
amount of the Premises so taken.  Tenant shall have no right or claim to any
part of any award made to or received by Landlord for such condemnation or
taking, and all awards for such condemnation or taking shall be made solely to

                                      -12-
<PAGE>

Landlord. Tenant shall, however, have the right to pursue any separate award
that does not reduce the award to which Landlord is entitled.

     30.  Service of Process.  Except as otherwise provided by law, Tenant
          ------------------
hereby appoints as its agent to receive the service of all dispossessory or
distraint proceedings and notices thereunder, the person in charge of or
occupying the Premises at the time of such proceeding or notice; and if no
person be in charge or occupying the Premises, then such service may be made by
attaching the same to the front entrance of the Premises.

     31.  Mortgagee's Rights.
          ------------------

          (a) Tenant agrees that this Lease shall be subject and subordinate (i)
to any mortgage, deed to secure debt or other security interest now encumbering
the Property and to all advances which may be hereafter made, to the full extent
of all debts and charges secured thereby and to all renewals or extensions of
any part thereof, and to any mortgage, deed to secure debt or other security
interest which any owner of the Property may hereafter, at any time, elect to
place on the Property; (ii) to any assignment of Landlord's interest in the
leases and rents from the Building or Property which includes the Lease which
now exists or which any owner of the Property may hereafter, at any time, elect
to place on the Property; and (iii) to any Uniform Commercial Code Financing
Statement covering the personal property rights of Landlord or any owner of the
Property which now exists or any owner of the Property may hereafter, at any
time, elect to place on the foregoing personal property (all of the foregoing
instruments set forth in (i), (ii) and (iii) above being hereafter collectively
referred to as "Security Documents").  Tenant agrees upon request of the holder
of any Security Documents ("Holder") to hereafter execute any documents which
the counsel for Landlord or Holder may deem necessary to evidence the
subordination of the Lease to the Security Documents.

          (b) In the event of a foreclosure pursuant to any Security Documents,
Tenant shall at the election of the Landlord, thereafter remain bound pursuant
to the terms of this Lease as if a new and identical Lease between the purchaser
at such foreclosure ("Purchaser"), as landlord, and Tenant, as tenant, had been
entered into for the remainder of the Term hereof and Tenant shall attorn to the
Purchaser upon such foreclosure sale and shall recognize such Purchaser as the
Landlord under the Lease.  Such attornment shall be effective and self-operative
without the execution of any further instrument on the part of any of the
parties hereto.  Tenant agrees, however, to execute and deliver at any time and
from time to time, upon the request of Landlord or of Holder, any instrument or
certificate that may be necessary or appropriate in any such foreclosure
proceeding or otherwise to evidence such attornment.

          (c) If the Holder of any Security Document or the Purchaser upon the
foreclosure of any of the Security Documents shall succeed to the interest of
Landlord under the Lease, such Holder or Purchaser shall have the same remedies,
by entry, action or otherwise for the non-performance of any agreement contained
in the Lease, for the recovery of Rent or for any other default or event of
default hereunder that Landlord had or would have had if any such Holder or
Purchaser had not succeeded to the interest of Landlord.

          (d) Tenant hereby acknowledges that if the interest of Landlord
hereunder is covered by an assignment of Landlord's interest in Lease, Tenant
shall pay all Rent due and payable under the Lease directly to the Holder of the
assignment of Landlord's interest in Lease upon notification of the exercise of
the rights thereunder by the Holder thereof.

          (e) Notwithstanding anything to the contrary set forth in this Section
31, the

                                      -13-
<PAGE>

Holder of any Security Documents shall have the right, at any time, to elect to
make this Lease superior and prior to its Security Document. No documentation,
other than written notice to Tenant, shall be required to evidence that the
Lease has been made superior and prior to such Security Documents, but Tenant
hereby agrees to execute any documents reasonably requested by Landlord or
Holder to acknowledge that the Lease has been made superior and prior to the
Security Documents.

          (f) Notwithstanding anything to the contrary contained in this Section
31, Tenant's subordination of the Lease to any Security Documents currently
encumbering the Premises is conditioned upon Landlord obtaining a subordination,
non-disturbance and attornment agreement substantially in the form attached
hereto as Exhibit G and made a part hereof (an "SNDA") from the Holder of any
          ---------
such Security Documents, which SNDA Tenant must execute simultaneously with the
execution of this Lease.

          (g) Notwithstanding anything to the contrary contained in this Section
31, this Lease and all rights of Tenant hereunder shall only be subject and
subordinate to the lien and security title of any Security Documents created
after the date hereof provided that the Holder of said Security Documents
executes and delivers an SNDA.  Tenant shall promptly execute such SNDA upon
Landlord's or such Holder's request.

     32.  Tenant's Estoppel.  Tenant shall, from time to time, upon not less
          -----------------
than ten (10) days prior written request by Landlord, execute, acknowledge and
deliver to Landlord a written statement certifying that this Lease is unmodified
and in full force and effect (or, if there have been modifications, that the
same is in full force and effect as modified and stating the modifications), the
dates to which the Rent has been paid, that Tenant is not in default hereunder
and has no offsets or defenses against Landlord under this Lease, and whether or
not to the best of Tenant's knowledge Landlord is in default hereunder (and if
so, specifying the nature of the default), it being intended that any such
statement delivered pursuant to this paragraph may be relied upon by a
prospective purchaser of Landlord's interest or by a mortgagee of Landlord's
interest or assignee of any security deed upon Landlord's interest in the
Premises.

     33.  Attorney's Fees and Homestead.  If either party exercises any of the
          -----------------------------
remedies provided to it under this Lease as a result of the other party's
failure to comply with its obligations, or if either party brings any action to
enforce its rights under this Lease, the defaulting party shall be obligated to
reimburse the non-defaulting party, on demand, for all costs and expenses,
including reasonable attorneys' fees and court costs, actually incurred in
connection therewith.  Tenant waives all homestead rights and exemptions which
he may have under any law against any obligations owing under this Lease and
Tenant hereby assigns to Landlord his homestead and exemption.

     34.  Parking.  No rights to specific parking spaces are granted under this
          -------
Lease; however, subject to Landlord's rights pursuant to the last sentence of
this Section 34, Tenant shall be entitled, without charge,  to use up to 3
spaces per each 1,000 rentable square feet of space in the Premises in the
parking facilities located on the Property.  All parking spaces provided to
Tenant shall be unreserved and are to be used by Tenant, its employees and
invitees in common with the other tenants of the Building and their employees
and invitees.  Subject to Tenant's rights herein, Landlord reserves the right to
build improvements upon, reduce the size of, relocate, reconfigure, eliminate,
and/or make alterations or additions to such parking facilities at any time.

          (b) Tenant shall be responsible for the removal and disposal of any
waste deemed by any governmental authority having jurisdiction over the matter
to be hazardous or infectious waste or waste requiring special handling, such
removal and disposal to be in accordance with any and all applicable
governmental rules, regulations, codes, orders or requirements.  Tenant agrees
to separate and mark appropriately all waste to be removed and disposed of
through the janitorial service pursuant to (a) above and hazardous, infectious
or special waste to be removed and disposed of by Tenant pursuant to this
subparagraph (b).  Tenant hereby indemnifies and holds harmless Landlord from
and against any loss, claims, demands, damage or injury Landlord may suffer or
sustain as a result of Tenant's failure to comply with the provisions of this
subparagraph (b).

     37.  Surrender of Premises.  Whenever under the terms hereof Landlord is
          ---------------------
entitled to possession of the Premises, Tenant at once shall surrender the
Premises and the keys thereto to Landlord in the same condition as on the
Commencement Date hereof, natural wear and tear and casualty and condemnation
only excepted, and Tenant shall remove all of its personalty therefrom and
shall, if directed to do so by Landlord, remove all improvements and restore the
Premises to its original condition prior to the construction of any improvements
which have been made therein by or on behalf of Tenant subsequent to the
Commencement Date; provided, however, that in connection with any alterations or
improvement made by or on behalf of Tenant in accordance with Section 12 hereof,
Tenant shall only be required to remove any such alterations or improvement and
restore the Premises if Landlord shall have conditioned its consent to such
alterations or improvement on such removal and restoration occurring at the
expiration of this Lease.  Tenant's obligation to observe or perform these
covenants shall survive the expiration or other termination of the Term of this
Lease.  If the last day of the Term of this Lease or any renewal falls on Sunday
or a legal holiday, this Lease shall expire on the business day immediately
preceding.

     38.  Cleaning Premises.  Upon vacating the Premises, Tenant agrees to
          -----------------
return the Premises to Landlord broom clean and in the same condition when
Tenant's possession commenced, natural wear and tear, casualty and condemnation
excepted.

     39.  No Estate In Land.  This contract shall create the relationship of
          -----------------
landlord and tenant between Landlord and Tenant; no estate shall pass out of
Landlord; Tenant has only a usufruct, not subject to levy or sale, and not
assignable by Tenant except with Landlord's consent.

     40.  Cumulative Rights.  All rights, powers and privileges conferred
          -----------------
hereunder upon the parties hereto shall be cumulative but not restrictive to
those given by law.

     41.  Paragraph Titles; Severability.  The paragraph titles used herein are
          ------------------------------
not to be considered a substantive part of this Lease, but merely descriptive
aids to identify the paragraph to which they refer. If any paragraph or
provision herein is held invalid by a court of competent jurisdiction, all other
paragraphs or severable provisions of this Lease shall not be affected thereby,
but shall remain in full force and effect.

     42.  Damage or Theft of Personal Property.  All personal property brought
          ------------------------------------
into the

                                      -15-
<PAGE>

Premises shall be at the risk of the Tenant only and Landlord shall not be
liable for theft thereof or any damage thereto occasioned by any acts of co-
tenants, or other occupants of the Building, or any other person, except, with
respect to damage to the Premises, as may be occasioned by the negligent or
willful act of the Landlord, its employees and agents.

     43.  Holding Over.  In the event Tenant remains in possession of the
          -------------
Premises after the expiration of the Term hereof, or of any renewal term, with
Landlord's written consent, Tenant shall be a tenant at will and such tenancy
shall be subject to all the provisions hereof, except that the monthly rental
shall be at 150% of the monthly Base Rent payable hereunder upon such expiration
of the Term hereof, or of any renewal term.  In the event Tenant remains in
possession of the Premises after the expiration of the Term hereof, or any
renewal term, without Landlord's written consent, Tenant shall be a tenant at
sufferance and may be evicted by Landlord without any notice, but Tenant shall
be obligated to pay rent for such period that Tenant holds over without written
consent at the same rate provided in the previous sentence and shall also be
liable for any and all other damages Landlord suffers as a result of such
holdover including, without limitation, the loss of a prospective tenant for
such space.  There shall be no renewal of this Lease by operation of law or
otherwise.  Nothing in this Section shall be construed as a consent by Landlord
for any holding over by Tenant after the expiration of the Term hereof, or any
renewal term.

     44.  Intentionally omitted.

     45.  Building Allowance and Tenant Finishes.
          --------------------------------------

          (a) Landlord will provide to Tenant an allowance (as the same may be
reduced as of the date hereof as hereinafter provided, the "Allowance") of
$345,000.00 to be applied to the cost of the Work and Additional Work described
in Exhibit "B".  For purposes hereof, the cost of the Work and Additional Work
   ----------
shall be deemed to include, but not be limited to, the cost of the Preliminary
Plans, the Plans and Specifications, all permits and all tenant buildout
relating thereto.  To the extent any of the Work is or has been performed by
Landlord prior to the date hereof, the cost thereof (as reasonably evidenced to
Tenant) shall be applied against and shall reduce the Allowance remaining as of
the date hereof on a dollar for dollar basis. Tenant and Landlord agree that all
costs of the Work and Additional Work in excess of such Allowance which are
requested by Tenant and approved by Landlord shall be paid by Tenant to Landlord
as follows:  twenty-five (25%) percent of Tenant's estimated costs prior to the
commencement of the Work, fifty percent (50%) of Tenant's estimated costs within
five (5) business days of Landlord's notice to Tenant that fifty percent (50%)
of the Work is complete and the balance of actual costs within five (5) business
days of "Substantial Completion" (as hereinafter defined).  The amount due for
each installment shall be set forth in a written invoice from Landlord.  Should
Tenant fail to pay for such excess costs when due as herein provided, such
amount due shall accrue interest at the annual rate of ten (10.0%) percent from
the date such payment is due until paid and the failure to pay such amount when
due shall be a default, subject to the provisions of Section 26.

          (b) The Work Letter attached hereto as Exhibit "B", and executed by
                                                 ----------

shall control in the event of a conflict with the provisions contained in this
Lease.

Building, annexed hereto, and all reasonable rules and regulations which

government and management of said Building, are hereby

or omissions of any other tenant, Tenant or third party that may interfere with
Tenant's use and enjoyment of the Premises.

          ----------------
parties and no representations, inducements, promises or agreements, oral or
otherwise, between the parties not embodied herein shall be of any force or
effect.

     49.  Limitation of Liability.  Landlord's obligations and liability with
          -----------------------
respect to this Lease shall be limited solely to Landlord's interest in the
Building, as such interest is constituted from time to time, and neither
Landlord nor any partner of Landlord, or any officer, director, shareholder, or
partner of any partner of Landlord, shall have any personal liability whatsoever
with respect to this Lease.

     50.  Submission of Agreement.  Submission of this Lease to Tenant for
          -----------------------
signature does not constitute a reservation of space or an option to acquire a
right of entry.  This Lease is not binding or effective until execution by and
delivery to both Landlord and Tenant.

     51.  Authority.  Each of the persons executing this Lease on behalf of
          ---------
Tenant does hereby personally represent and warrant that Tenant is a duly
organized and validly existing corporation, that Tenant is qualified to do
business in the State of Georgia, that Tenant has full right, power and
authority to enter into this Lease, and that each person signing on behalf of
Tenant is authorized to do so.

     52.  Intentionally omitted.

     53.  Broker Disclosure.  Landlord represents that it has dealt with no
broker in connection with this Lease.  Landlord agrees that, if any broker makes
a claim for a commission based upon the actions of Landlord, Landlord shall
indemnify, defend and hold Tenant harmless from any such claim.  Tenant
represents that it has dealt with no broker in connection with the Lease.
Tenant agrees that, if any other broker makes a claim for a commission based
upon the actions of Tenant, Tenant shall indemnify, defend and hold Landlord
harmless from any such claim.

          -------
either party under this Lease shall be in writing and must be given only by
certified mail, return receipt requested, by hand delivery or by nationally
recognized overnight courier service at the addresses set forth below.  Any such
notice shall be deemed given on the date sent or deposited for delivery in
accordance with one of the permitted methods described above.  The time period
for responding to any such notice shall begin on the date the notice is actually
received, but refusal to accept delivery or inability to accomplish delivery
because the party can no longer be found at the then current notice address,
shall be deemed receipt.  Either party may change its notice address by notice
to the other party in accordance with the terms of this Section 54.  The
following are the initial notice addresses for each party:

                                 (WORK LETTER)


     To induce Tenant to enter into the Lease (to which this Exhibit B is
attached) and in consideration of the mutual covenants hereinafter contained,
Landlord and Tenant agree as follows:

     1.   Landlord shall build out the 2/nd/ floor of the Premises substantially
in accordance with the preliminary plans and specifications and/or preliminary
floor plans set forth on Exhibit B-1 attached hereto and incorporated herein
                         -----------
(the "Preliminary Plans"; the work contemplated by the Preliminary Plans being
referred to herein as the "Work"). Tenant shall otherwise accept the Premises in
their AS IS condition. Within thirty (30) days after the date of the Lease,
Landlord shall prepare and submit to Tenant a set of plans and specifications
and/or construction drawings (collectively, the "Plans and Specifications")
based on the Preliminary Plans. Tenant shall have five (5) business days after
receipt of the Plans and Specifications in which to review and to give to
Landlord written notice of its approval of the Plans and Specifications or its
requested changes to the Plans and Specifications. Tenant shall have no right to
request any changes to the Plans and Specifications which would materially alter
either the Premises or the exterior appearance or basic nature of the Building,
as the same are contemplated by the Preliminary Plans. If Tenant fails to
approve or request changes to the Plans and Specifications by five (5) business
days after its receipt thereof, then Tenant shall be deemed to have approved the
Plans and Specifications and the same shall thereupon be final. If Tenant
requests any changes to the Plans and Specifications, Landlord shall make those
changes which are reasonably requested by Tenant and shall within ten (10) days
of its receipt of such request submit the revised portion of the Plans and
Specifications to Tenant. Tenant may not thereafter disapprove the revised
portions of the Plans and Specifications unless Landlord has unreasonably failed

Plans and Specifications, as modified by said revisions, shall be deemed to be
final upon the submission of said revisions to Tenant. Tenant shall at all times
in its review of the Plans and Specifications, and of any revisions thereto, act
reasonably and in good faith. After Tenant has approved the Plans and
Specifications or the Plans and Specifications have otherwise been finalized
pursuant to the procedures set forth hereinabove, any subsequent changes to the
Plans and Specifications requested by Tenant shall be at Tenant's sole cost and
expense and subject to Landlord's written approval, which approval shall not be
unreasonably withheld, conditioned or delayed. Landlord shall use reasonable
speed and diligence to "Substantially Complete" the Work.

     2.   Any other work desired by Tenant, and approved by Landlord (which
approval shall not be unreasonably withheld), shall be performed by Landlord or
Landlord's contractors, unless Landlord otherwise consents in writing.  If
Tenant desires any work in addition to the Work described in Section 1 hereof
("Additional Work"), Tenant shall submit to Landlord or Landlord's agent (at
Tenant's sole cost and expense) the necessary drawings, plans and specifications
for the Additional Work within five (5) days of the date of the Lease.  Prior to
commencing any such Additional Work requested by Tenant, Landlord or Landlord's
agent shall submit to Tenant a written estimate of the cost of such Additional
Work.  If Tenant shall fail to approve said estimate within seven (7) days from
the receipt thereof, the same shall be deemed disapproved in all respects by
Tenant and Landlord shall not be authorized to proceed thereon. If Tenant
desires any changes in the Additional Work after having approved the initial
plans and
<PAGE>

cost estimate, Tenant shall be required to sign such field order changes
requested by Landlord or Landlord's contractors or agents to evidence any such
change desired by Tenant. Tenant acknowledges that no cost estimate will be
given for any changes in the Additional Work after the initial cost estimate has
been approved by Tenant, and Tenant shall be responsible for any and all costs
associated with any such change. The Allowance shall be applied toward the cost
of the Work and the excess, if any, toward the Additional Work. Any costs of the
Work and Additional Work in excess of the Allowance specified in the Lease shall
be due and payable from Tenant to Landlord as provided in Section 45 of the
Lease.

     3.   For purposes of this Lease, the term "Substantial Completion" (or any
variation thereof) shall mean completion of construction of the Work in
accordance with the Plans and Specifications, subject only to Punchlist items
established as hereinafter set forth, so that Tenant can lawfully occupy and
conduct its business on the 2/nd/ floor of the Premises, as established by the
delivery by Landlord to Tenant of a certificate of occupancy (or temporary
certificate of occupancy or its equivalent) for the 2/nd/ floor of the Premises
issued by the appropriate governmental authority, if a certificate is so
required by a governmental authority (and if it is not so required, then
"Substantial Completion" shall be evidenced by a Certificate of Substantial
Completion on standard AIA Form G-704 certified by Landlord's architect). If the
Substantial Completion of the Work by Landlord is delayed due to any act or
omission of Tenant or Tenant's representatives, including any delays by Tenant
in the submission of plans, drawings, specifications or other information or in
approving any drawings or estimates or in giving any authorization or approval,
the Work shall be deemed Substantially Completed on the date when they would
have been Substantially Complete but for such delay. Upon Substantial Completion
of the Work, a representative of Landlord and a representative of Tenant
together shall inspect the Work and generate a punchlist of defective or
uncompleted items relating to the completion of the Work (the "Punchlist"),
which Punchlist shall be incorporated into the certificate to be executed and
delivered by each of the parties upon such Substantial Completion in the form
attached hereto as Exhibit "E" (the "Completion Certificate"). Landlord shall,
within a reasonable time after the Punchlist is prepared and agreed upon by
Landlord and Tenant (and such certificate is executed and delivered by tenant as
aforesaid), complete such incomplete work and remedy such defective work as is
set forth on the Punchlist. All construction work performed by Landlord shall be
deemed approved by Tenant in all respects except for items of said work which
are not completed or do not conform to the Plans and Specifications and which
are included on the Punchlist upon the execution and delivery of the Completion
Certificate.

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

THIS AGREEMENT ("Agreement") made as of the ____ day of ___________________,
2000, by and among THE PRUDENTIAL INSURANCE COMPANY OF AMERICA (together with
its successors or assigns in interest, collectively "Lender"), National Data
Corporation ("Landlord"), Global Payments Inc. ("Tenant").


                               R E C I T A L S:
                               ---------------

Lender is the owner and the holder of a loan evidenced by a promissory note (the
"Note") dated  April 16, 1998 and amended April 29, 1999 in the face amount of
               -----------------------------------------
$3,500,000. The Note is secured by a Deed to Secure Debt and Security Agreement
(the "Mortgage") dated the same date as said Note, and recorded at the Real
Property Records of the Dekalb County, Georgia clerk of superior court, Book
9948, page 16, covering the real property described therein (the "Mortgaged
Premises").

Tenant is the tenant under that certain Lease Agreement dated __________________
(the Lease"), between Tenant and National Data Corporation as landlord (said
landlord and its successors and assigns under the Lease hereinafter collectively
called "Landlord"), covering all or part of the Mortgaged Premises as set forth
under the Lease (hereinafter called the "Demised Premises").

Tenant and Lender desire to confirm their understanding with respect to the
Lease and the Mortgage.

     THEREFORE, in consideration of the mutual covenants and agreements herein
contained and other good valuable consideration, the receipt and sufficiency of
which are hereby acknowledged by all parties, Lender and Tenant agree as
follows:

     1.   Subordination. Subject in all respects to the provisions of this
          -------------
Agreement, the Lease is now, and will at all times and for all purposes be
subordinate, in every respect, to the Mortgage. The Lease is subordinate, in
each and every respect, to any and all increases, renewals, modifications,
extensions, substitutions, replacements and/or consolidations of the Mortgage,
(collectively a "Modification"), provided that any and all Modifications shall
nevertheless be subject to the terms of this Agreement.

     2.   Non-Disturbance. So long as Tenant is not in material default under
          ---------------
the Lease beyond the expiration of all applicable notice and cure periods,
Tenant shall not be joined as a party defendant in any actions to foreclose the
Mortgage, and the Lease shall not be terminated,


<PAGE>

nor shall Tenant's use, possession or enjoyment of the Demised Premises for the
balance of the term or extensions or renewals thereof, or any of the rights or
privileges of Tenant under or provided by the Lease, be terminated or disturbed
in any way, by any foreclosure or exercise of private power of sale or any other
action or proceeding instituted under or in connection with the Mortgage in case
Lender takes possession of the Mortgaged Premises pursuant to any provisions
thereof.

     3.   Attornment. If Lender or any other party succeeds to the interest of
          ----------
Landlord under the Lease in any manner, including but not limited to
foreclosure, exercise of any power of sale, succession by deed in lieu or other
conveyance (a "Succession"), such party shall be deemed to have assumed the
obligations of the Landlord thereafter arising, accruing or to be performed, and
Tenant will attorn to and be bound to such party (whether Lender or another
party) after receiving notice of such Succession and will recognize Lender or
such other party as the landlord under the Lease. Such attornment and the
provisions of this Agreement shall be effective and self-operative without the
execution of any further instrument. Tenant, upon request, will sign and deliver
any instruments reasonably requested to evidence such attornment. Tenant waives
the provisions of any statute or rule of law, now or hereafter in effect, which
may give or purport to give Tenant any right or election to terminate or
otherwise adversely affect the Lease and the obligations of Tenant thereunder as
a result of any such foreclosure or trustee's sale.

     4.   Limitation On Lender's Liability. Upon any Succession, Lender shall
          --------------------------------
not be (a) liable for any act or omission of the Landlord under said Lease,
except to the extent the same constitutes a continuing default under the Lease
following such party's acquisition of title of the Mortgaged Premises, (b)
subject to any offsets or defenses which Tenant may have against the Landlord
arising or occurring prior to the Succession, except for offsets arising under
the Lease after Lender has received notice and opportunity to cure pursuant to
Paragraph 6 below, (c) bound by any rent or additional rent which Tenant may
have paid to Landlord for more than the current month, unless paid to Lender or
otherwise actually received by Lender, (d) bound by any material amendment or
modification of the Lease made without Lender's prior written consent, (e)
liable for any security deposit paid by Tenant to Landlord unless such deposit
is delivered to Lender, (f) liable for or obligated to pay for repairs,
replacements, damages or allowances not made, performed or paid by the Landlord
if such performance or payment was due prior to the Succession, or (g) liable
for the payment of any leasing commissions, the triggering event for which arose
or occurred prior to the Succession. Any reference to Landlord includes all
prior landlords under the Lease.

     5.   Tenant's Warranty. Tenant warrants to Lender, as of the date hereof,
          -----------------
that (a) attached is a true, correct and complete copy of the Lease, (b) To
Tenant's actual knowledge there are no defaults on the part of Landlord under
the Lease, (c) the Lease is a complete statement of the agreement of the parties
with respect to the leasing of the Demised Premises, and (d) the Lease is
validly executed by Tenant and in full force and effect. Tenant acknowledges and
warrants to Lender that it has not knowingly subordinated the Lease or any of
its rights under the Lease to any lien or mortgage other than the Mortgage.

     6.   Lender Cure Rights. Tenant agrees to give Lender a copy of any notice
          ------------------
of default ("Default Notice") which Tenant provides to Landlord under the Lease
by sending such written

<PAGE>

notice to Lender at Suite 1400, Two Ravinia Drive, Atlanta, Georgia 30346,
referencing Loan Number 6102570 by certified mail, return receipt requested.
After receipt of a Default Notice, Lender shall have the right, but not the
obligation, to correct or cure the Landlord default within 10 days after the end
of the cure period provided Landlord by the Lease terms. Until such period
expires, within which Lender may correct or cure the default, Tenant agrees to
take no action to exercise remedies provided to Tenant under the Lease terms.
Tenant will accept Lender's cure of any Landlord default. Landlord acknowledges
and consents to the foregoing.

     7.   Rent Payment. Immediately upon written notice to Tenant (a) that
          ------------
Lender has been entitled to collect rents pursuant to its rights under the
Mortgage or any other loan documents acting to secure the Note following a
default under the Loan, or (b) of Lender's succeeding to the Landlord's interest
under the Lease, Tenant agrees to pay all rents due under the Lease directly to
Lender (in accordance with the Lease). Landlord consents to the foregoing and
authorizes and directs Tenant to make payment of such monies to Lender after
Tenant's receipt of such notice. Landlord agrees that any payments so made by
Tenant after receipt of such a notice shall be applied and credited toward
Tenant's obligations under the Lease, regardless of whether Lender was properly
authorized to require such payments from Tenant, and Landlord releases Tenant
from any claim relative to Tenant's payment to Lender based on Lender's demand.

     8.   Complete Agreement. This Agreement supersedes, as between the parties
          ------------------
hereto, all of the terms and provisions of the Lease which are inconsistent
herewith.

     9.   No Oral Modification/Binding Effect. This Agreement may not be
          -----------------------------------
modified orally or in any manner other than by an agreement in writing signed by
the parties hereto or their respective successors in interest. This Agreement
shall inure to the benefit of and be binding upon the parties hereto and their
successors and assigns.

     10.  Laws. This Agreement shall be construed in accordance with the laws of
          ----
the State where the Mortgaged Premises are located.

     11.  Automatic Amendment of Lease. Upon a Succession, the Lease is
          ----------------------------
automatically amended as follows:

     a.   Hazardous Materials. All representations, warranties, indemnities or
          -------------------
     hold harmless provisions in favor of Tenant from Landlord dealing with the
     presence, use, transportation, disposal, contamination, exposure to or in
     any way arising out of hazardous or toxic materials, chemicals or wastes
     ("Hazardous Materials") are deleted as to Lender. Lender, however, as
     Landlord, covenants and agrees to (a) comply with all laws governing
     Hazardous Materials ("Hazardous Materials Laws"), (b) store, use and
     dispose of all Hazardous Materials at the Mortgaged Premises in accordance
     with all applicable Hazardous Materials Laws, and (c) remove, remediate
     and/or clean up, as applicable, in accordance with all applicable Hazardous
     Materials Laws, all Hazardous Materials at the Mortgaged Premises (to the
     extent not caused by Tenant or its employees, contractors or agents)
     impairing Tenant's use or access to the Demised Premises.

<PAGE>

     b.   Insurance. Tenant will at all times carry liability coverage for its
          ---------
     activities and operations at the Demised Premises, listing Lender and
     Landlord as additional insureds, in accordance with such coverage amounts
     as are required by the Lease. Lender will have no liability to Tenant for
     any indemnity or hold harmless provision under the Lease where Lender is
     otherwise covered by Tenant's liability coverage(s) as carried by Tenant or
     which Tenant is required to carry under the Lease. All insurance required
     to be carried by Landlord under the Lease may be effected by Lender by
     self-insurance or by a policy or policies of blanket insurance covering
     additional items or locations or assureds and with such deductibles as
     Lender may from time to time determine. Tenant has no rights in any policy
     or policies maintained by Lender.


          IN WITNESS WHEREOF, the parties hereto have caused this Agreement to
     be duly executed the day and year first above written.
