         I. All terms, covenants and conditions contained in this Second

         rental for September 2000 shall also be due and payable in the amount
         of $2,312.63. Together with the execution of this Second Amendment,

6.       Tenant Improvement Allowance: "As Is". Landlord shall have no
         obligation to perform any construction or make any additional

         improvements or alterations, in connection with this Second Amendment.
         Tenant acknowledges and agrees that all construction obligations of
         Landlord under the Lease have been performed in full and accepted, and
         Tenant hereby accepts New Suite 730 in its "as is" condition. Landlord
         will install a lock on the entrance door to Suite 730 and key the same
         as Suite 780. Landlord at Tenant's cost will provide New Suite 730 with
         150 amps of 480 volt power.

         whose commission shall be paid by the Landlord. Each of the parties
         agrees to indemnify, defend and protect the other from and against, any

         a part. The obligations of Landlord under the Lease shall not be
         personally binding on, nor shall any resort be had to the private
         properties of, any of its trustees or board of directors and officers,
         as the case may be, the general partners thereof or any beneficiaries,
         stockholders, employees or agents of Landlord, or the investment

         (3)      Landlord agrees to perform the work required to be performed
                  by Landlord under the Lease Improvement Agreements with
                  diligence, subject to events and delays due to causes beyond
                  Landlord's reasonable control. The Initial Premises and the
                  Third Floor Expansion Premises shall be deemed substantially
                  completed and possession delivered when Landlord has
                  substantially completed the work to be constructed or
                  installed pursuant to the provisions of the Primary Lease
                  Improvement Agreement with respect thereto, subject only to
                  the completion of items on Landlord's Punch List (and
                  exclusive of the installation of all telephone and other
                  communications facilities and equipment and other finish work
                  to be performed by parties other than Landlord). In the event
                  of any dispute as to when and whether the work performed or
                  required to be performed by Landlord has been substantially
                  completed, the certificate of an A.I.A. registered architect
                  rendering services with respect to the Tenant Improvements on
                  or about the Initial Premises or the Third Floor Expansion
                  Premises, as the case may be, or a temporary or final
                  certificate of occupancy issued by the local governing
                  authority shall be conclusive evidence of such completion,
                  effective on the date of said architect's certificate or said
                  temporary or final certificate of occupancy. Landlord shall
                  deliver Landlord's Punch List to Tenant simultaneously with
                  the delivery of the Initial Premises and the Third Floor
                  Expansion Premises, as the case may be. Tenant shall approve
                  or make reasonable additions to Landlord's Punch List within
                  five (5) days after delivery of the Initial Premises and the
                  Third Floor Expansion Premises, as the case may be. Subject to
                  delays caused by Tenant or otherwise beyond Landlord's
                  reasonable control, Landlord shall complete the items listed
                  on Landlord's Punch List within thirty (30) days following
                  delivery of the Initial Premises and the Third Floor Expansion
                  Premises, as the case may be.

         (4)      If substantial completion of the Third Floor Expansion
                  Premises, or possession thereof by Tenant, is delayed because
                  any tenant or other occupant thereof holds over and the
                  Landlord is delayed, using good faith efforts in Landlord's
                  discretion in acquiring possession thereof, Landlord shall not
                  be deemed in default, nor in any way liable to Tenant because
                  of such delay, and Tenant agrees to accept possession of such
                  premises at such time as Landlord is able to tender the same,
                  which date shall thenceforth be deemed the Third Floor
                  Expansion Effective Date notwithstanding any other provision
                  hereof to the contrary.

         (5)      The taking of possession by Tenant shall be deemed
                  conclusively to establish that the Building and the Premises
                  with respect to which possession is so taken have been
                  completed in accordance with the plans and specifications and
                  are in good and satisfactory condition as of when possession
                  was so taken (except for such items, if any, as are described
                  in Landlord's Punch List). Contemporaneously with execution of
                  this Lease and thereafter and upon the occurrence of each of
                  the Third Floor Expansion Effective Date and the Fourth Floor
                  Expansion Effective Date, Tenant shall execute and deliver to
                  Landlord a commencement and estoppel certificate in the form
                  attached hereto as Exhibit "D" and by this reference
                  incorporated herein, as modified to accurately reflect the
                  terms of this Lease.

5.       RENT

         (1)      Tenant shall pay to Landlord Base Rent as set forth in
                  Paragraph 1 hereof and other items of Rent as set forth herein
                  commencing on the Commencement Date and throughout the Lease
                  Term, monthly in advance (unless otherwise specified in this
                  Lease) on or before the first day of each month during the
                  term hereby demised in lawful money of the United States,
                  without demand, deduction or offset whatsoever, to Landlord at
                  Landlord's Address or to such other firm or to such other
                  place as Landlord may from time to time designate in writing.
                  If the Commencement Date occurs on a day other than the first
                  day of a calendar month, the monthly rental for such month
                  shall be appropriately prorated.

         (2)      Tenant agrees that if Rent or any other payment due hereunder
                  from Tenant to Landlord remains unpaid ten (10) days after
                  said amount is due, the amount of such unpaid rent or other
                  payment shall be increased by a late charge to be paid to
                  Landlord by Tenant in an amount equal to the greater of (i)
                  Fifty and No/100 Dollars ($50.00) per day that such payment is
                  delinquent, or (ii) five percent (5%) of the amount of the
                  delinquent rent or other payment. The amount of the late
                  charge to be paid to Landlord by Tenant for any month shall be
                  computed on the aggregate amount of delinquent rents and other
                  payments, including all accrued late charges, then
                  outstanding. Tenant agrees that such amount is a reasonable
                  estimate of the loss and expense to be suffered by Landlord as
                  a result of such late payment by Tenant and may be charged by
                  Landlord to defray such loss and expense. The provisions of
                  this paragraph in no way relieve Tenant of the obligation to
                  pay Rent or other payments on or before the date on which they
                  are due, nor do the terms of this paragraph in any way affect
                  Landlord's remedies pursuant to Paragraph 21 of this Lease in
                  the event said Rent or other payment is unpaid after the date
                  due.

6.       ADJUSTMENTS TO RENT

         (1)      [INTENTIONALLY OMITTED]

         (2)      Tenant's Share of Increased Operating Costs. In addition to
                  payment of Base Rent and all other charges provided for in
                  this Lease, Tenant shall pay as part of Rent Tenant's Pro Rata
                  Share of any increase in the total annual Operating Costs.
                  Said payments shall be made in the following manner:

                  (i) At least thirty (30) days prior to the commencement of
each Calendar Year during the term hereof, Landlord shall furnish Tenant with a
written statement, prepared in good faith, setting forth the Estimated Costs for
such Calendar Year, and a statement showing the amount by which Tenant's Pro
Rata Share of the Estimated Costs exceeds Tenant's pro rata share of Base Year
Operating Costs. Tenant shall pay one-twelfth (1/12) of its Pro Rata Share of
such excess monthly.

                  (ii) Within ninety (90) days after the close of each Calendar
Year, Landlord shall deliver to Tenant a written statement setting forth the
Actual Costs during that Calendar Year. If such Actual Costs exceed the
Estimated Costs paid by Tenant to Landlord for such Calendar Year, Tenant shall
pay to Landlord its Pro Rata Share of such excess within forty-five (45) days
after receipt of such statement. If the statement shows such Actual Costs to be
less than the Estimated Costs, then Landlord shall credit the difference against
rent due for the calendar months next following receipt of Landlord's written
statement, or refund the difference to Tenant if the term has expired.

         (3)      Gross Up of Operating Costs. Anything to the contrary in this
                  Paragraph 6 notwithstanding, in the event that the Building is
                  not at least 95% occupied during any period of calendar year
                  1999 or any subsequent or Calendar Year, Landlord shall make

                                       9
<PAGE>   10

                  reasonable adjustments necessary to project what the Actual
                  Costs would have been had the Building been 95% occupied
                  during the full term of the year and those projected Operating
                  Costs shall be deemed to be the Actual Costs for purposes of
                  this Paragraph.

7.       COMPLIANCE WITH LAWS

         Tenant shall not use the Premises or permit anything to be done in or
about the Premises which will in any way conflict with any law, statute,
ordinance, or governmental rule or regulation now in force or which may
hereafter be enacted or promulgated. Except as may be contemplated by the
provisions of Paragraphs 4, 5, 6, 8 and 14 of the Special Stipulations, Tenant
shall not do or permit anything to be done on or about the Premises or bring or
keep anything therein which will in any way increase the rate of any insurance
upon the Building or any of its contents or cause a cancellation of said
insurance or otherwise affect said insurance in any manner and Tenant shall, at
its sole cost and expense, promptly comply with all laws, statutes, ordinances,
and governmental rules, regulations, or requirements now in force or which may
hereafter be in force and with the requirements of any board of fire
underwriters or other similar body now or hereafter constituted relating to or
affecting the condition, use, or occupancy of the Premises, excluding structural
changes not related to or affected by alterations or improvements made by or for
Tenant or Tenant's acts. The judgment of any court of competent jurisdiction or
the admission of Tenant in an action against Tenant, whether Landlord be a party
thereto or not, that Tenant has so violated any such law, statute, ordinance,
rule, regulation, or requirement, shall be conclusive evidence of such violation
as between Landlord and Tenant.

8.       ALTERATIONS

         Tenant shall not make or suffer to be made any alterations, additions,
or improvements in, on, or to the Premises or any part thereof without the prior
consent of Landlord. Any such alterations, additions, or improvements in, on, or
to said Premises, except for Tenant's movable furniture and equipment, shall, at
Landlord's election, immediately become Landlord's property. Except as otherwise
provided in the Special Stipulations, at the expiration or sooner termination of
the term herein provided, such alterations, additions or improvements shall, at
Landlord's option, either (i) remain on the Premises without compensation to
Tenant, or (ii) with respect to alterations made after the Commencement Date
(other than Tenant Improvements), be removed by Tenant at Tenant's sole cost and
expense and Tenant shall forthwith and with all due diligence, at its sole cost
and expense, repair and restore the Premises to the condition existing prior to
installation of such alterations, ordinary wear and tear excepted. At the time
that Tenant request's Landlord's prior consent to any alteration, Tenant may
request Landlord's determination as to whether such alteration, addition or
improvement shall, at the termination of the Lease, remain a part of the
Premises as Landlord's property, or be removed by Tenant as described
hereinabove. In the event Landlord consents to the making of any alteration,
addition, or improvement by Tenant, the same shall be made by Tenant, at
Tenant's sole cost and expense, in accordance with all applicable laws,
ordinances, and regulations and all requirements of Landlord's and Tenant's
insurance policies, and in accordance with plans and specifications approved by
Landlord. Any contractor, subcontractor or other person selected by Tenant to
make such alterations, additions or improvements, must first be approved in
writing by Landlord, or, at Landlord's option, the alteration, addition, or
improvement shall be made by Landlord for Tenant's account and Tenant shall
reimburse Landlord for the cost thereof within twenty (20) days after receipt of
a statement. Landlord and Tenant recognize that some types of alterations,
additions or improvements to the Premises may affect the density of use of the
Premises, and that such changes may require mechanical changes in how Building
services are provided to the Premises. Therefore, in considering any proposed
alterations, additions or improvements, Landlord may also require that Tenant
reimburse Landlord for the cost of changes to mechanical systems providing
Building services to the Premises (e.g., re-routing or otherwise adjusting HVAC
conduits serving the Premises). Landlord shall have the right to assess an
administrative fee to cover Landlord's expense in reviewing any proposed
alteration, addition or improvement (other than with respect to the Tenant
Improvements with respect to which Tenant is required to pay a construction
management fee in

                                       10
<PAGE>   11

accordance with the terms of the Leasehold Improvement Agreements). In addition,
subject in all respects to the qualifications contained in the parenthetical
contained in the immediately preceding sentence, if such alteration, addition or
improvement is approved, Landlord shall also have the right to assess an
administrative fee to cover Landlord's expense in supervising Tenant's work in
implementing such alteration, addition or improvement. Such assessments of
administrative fees shall be payable upon demand, and shall be considered part
of Rent under this Lease.

9.       REPAIR

         (1)      By taking possession of the Premises, Tenant accepts the
                  Premises with respect to which possession is so taken as being
                  in the condition in which Landlord is obligated to deliver
                  them and otherwise in good order, condition and repair (except
                  for such items, if any, as are described in Landlord's Punch
                  List). Tenant shall, at all times during the term hereof at
                  Tenant's sole cost and expense, keep the Premises and every
                  part thereof in good order, condition and repair, excepting
                  ordinary wear and tear, damage thereto by fire, earthquake,
                  Act of God or the elements. Tenant shall upon the expiration
                  or sooner termination of the term hereof, unless Landlord
                  demands otherwise as in Paragraph 8 hereof provided, surrender
                  to Landlord the Premises and all repairs, changes,
                  alterations, additions, and improvements thereto in the same
                  condition as when received, or when first installed, ordinary
                  wear and tear, damage by fire, earthquake, Act of God, or the
                  elements excepted. It is hereby understood and agreed that
                  Landlord has no obligation to alter, remodel, improve, repair,
                  decorate, or paint the Premises or any part thereof except as
                  specified in the Initial Premises Lease Improvement Agreement
                  and the Expansion Space Lease Improvement Agreement, and that
                  no representations respecting the condition of the Premises or
                  the Building have been made by Landlord to Tenant, except as
                  specifically herein set forth.

         (2)      Tenant shall repair all damage to the Building including
                  common areas, restrooms, hallways, elevators, or any other
                  area, fixture, or equipment of the Building caused by Tenant's
                  installation or removal of its property or resulting from any
                  negligent act or conduct of Tenant, its employees,
                  contractors, agents, licensees or invitees.

         (3)      All maintenance or repairs made by Tenant shall be made in
                  accordance with all applicable laws, ordinances and
                  regulations, and all requirements of Landlord's and Tenant's
                  insurance policies and any contractor or person selected by
                  Tenant to make the same, and all subcontractors must first be
                  approved in writing by Landlord, or, at Landlord's option, the
                  maintenance or repair shall be made by Landlord for Tenant's
                  account and Tenant shall reimburse Landlord for the cost
                  thereof within twenty (20) days after receipt of a statement.
                  In any event, all repairs shall be equal in quality and
                  workmanship to the original work.

10.      LIENS

         Tenant shall keep the Premises free from any liens arising out of any
work performed, material furnished, or obligations incurred by Tenant. In the
event that Tenant shall not, within ten (10) days following the imposition of
any such lien, cause the same to be released of record by payment or posting of
a proper bond, Landlord shall have, in addition to all other remedies provided
herein and by law, the right, but not the obligation, to cause the same to be
released by such means as it shall deem proper, including payment of the claim
giving rise to such lien. All such sums paid by Landlord and all expenses
incurred by it in connection therewith shall be considered additional rent and
shall be payable to it by Tenant on demand and with interest at the rate of
eighteen percent (18%) per annum or the rate four percent (4%) higher than the
prime commercial lending rate from time to time of Wachovia Bank, N.A.,

                                       11
<PAGE>   12

whichever is more, provided however that if such rate exceeds the maximum rate
permitted by law the maximum lawful rate shall apply; the interest rate so
determined is hereinafter called the "Agreed Interest Rate." Landlord shall have
the right at all times to post and keep posted on the Premises any notices
permitted or required by law, or which Landlord shall deem proper for the
protection of Landlord, the Premises, the Building, and any other party having
an interest therein, from mechanics' and materialmen's liens, and Tenant shall
give to Landlord at least five (5) business days prior written notice of
commencement of any construction on the Premises.

11.      ASSIGNMENT AND SUBLETTING

                                       12
<PAGE>   13

         (1)      Tenant shall not sell, assign, encumber, or otherwise transfer
                  by operation of law or otherwise this Lease or any interest
                  herein, sublet the Premises or any portion thereof, or suffer
                  any other person to occupy or use the Premises or any portion
                  thereof, without the prior written consent of Landlord as
                  provided herein, nor shall Tenant permit any lien to be placed
                  on the Tenant's interest by operation of law. Tenant shall, by
                  written notice, advise Landlord of its desire from and after a
                  stated date (which shall not be less than thirty (30) days nor
                  more than ninety (90) days after the date of Tenant's notice)
                  to sublet the Premises or any portion for any part of the term
                  hereof; and in such event Landlord shall have the right, to be
                  exercised by giving written notice (a "Recapture Notice") to
                  Tenant within fifteen (15) business days after receipt of
                  Tenant's notice, to terminate this Lease as to the portion of
                  the Premises described in Tenant's notice and such notice
                  shall, if given, terminate this Lease with respect to the
                  portion of the Premises therein described as of the date
                  stated in Tenant's notice; provided, however, that Tenant may
                  elect to withdraw any such assignment or subletting notice
                  upon receipt of a Recapture Notice from Landlord by delivering
                  written notice (a "Reinstatement Notice") to Landlord of such
                  withdrawal within three (3) business days from receipt of a
                  Recapture Notice and, upon receipt by Landlord of the
                  Reinstatement Notice, the original notice sent by Tenant to
                  Landlord for purposes of requesting an assignment or sublease
                  of Tenant's interest hereunder shall be withdrawn and this
                  Lease shall remain unaltered and in full force and effect. Any
                  assignment or subletting notice by Tenant shall state the name
                  and address of the proposed subtenant, and Tenant shall
                  deliver to Landlord a true and complete copy of the proposed
                  sublease with said notice. If said notice shall specify all of
                  the Premises and Landlord shall give a Recapture Notice with
                  respect thereto, this Lease shall terminate on the date stated
                  in Tenant's notice (unless any such Recapture Notice is
                  withdrawn as provided hereinabove by Tenant's timely delivery
                  of a Reinstatement Notice to Landlord). If, however, this
                  Lease shall terminate pursuant to the foregoing with respect
                  to less than all the Premises, the rent, as defined and
                  reserved hereinabove and as adjusted pursuant to Paragraph 6,
                  shall be adjusted on a pro rata basis to the number of square
                  feet retained by Tenant, and this Lease as so amended shall
                  continue thereafter in full force and effect. If Landlord,
                  upon receiving said notice by Tenant with respect to any of
                  the Premises, shall not exercise its right to terminate,
                  Landlord will not unreasonably withhold or delay its consent
                  to Tenant's subletting the Premises specified in said notice.
                  Landlord, acting reasonably and in good faith, may deny
                  consent to an assignment or sublease if, by way of
                  illustration but not limitation, (i) the credit rating of the
                  proposed assignee or sublessee is unacceptable, (ii) the type
                  of business to be conducted by the proposed assignee or
                  sublessee on the Premises is in violation of any exclusive
                  rights granted to other tenants of the Building or is
                  inappropriate for a first class office building, (iii) the
                  density of use of the Premises by the proposed assignee or
                  sublessee is significantly greater than the then current
                  density of use of the Premises by Tenant, or (iv) 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. Tenant shall, at
                  Tenant's own cost and expense, discharge in full any
                  outstanding commission obligation on the part of Landlord with
                  respect to this Lease, and any commissions which may be due
                  and owing as a result of any proposed assignment or
                  subletting, whether or not the Lease is terminated pursuant
                  hereto and rented by Landlord to the proposed subtenant or any
                  other tenant. Tenant shall pay to Landlord immediately upon
                  receipt fifty percent (50%) of all rent or other consideration
                  received by Tenant from any such assignee or subtenant, either
                  initially or over the term of the assignment or sublease,
                  which is in excess of (x) the rental obligation required under
                  the terms of this Lease for the Premises or portion thereof
                  for which consent is granted, and (y) marketing fees,
                  brokerage

                                       13
<PAGE>   14

                  commissions and build-out expenses of Tenant in entering into
                  such assignment or sublease.

         (2)      Any subletting hereunder by Tenant shall not result in
                  Tenant's being released or discharged from any liability under
                  this Lease. As a condition to Landlord's prior written consent
                  as provided for in this Paragraph 11, the subtenant or
                  subtenants shall agree in writing to comply with and be bound
                  by all of the terms, covenants, conditions, provisions, and
                  agreements of this Lease, and Tenant shall deliver to Landlord
                  promptly after execution, an executed copy of each sublease
                  and an agreement of said compliance by each subtenant. If an
                  event of default, as hereinafter defined, should occur while
                  the Premises or any part thereof are then sublet, Landlord, in
                  addition to any other remedies herein provided or provided by
                  law, may at its option collect directly from the subtenant all
                  rents and other sums becoming due to Tenant under the sublease
                  and apply the rent against any sums due to Landlord by Tenant
                  hereunder, and Tenant hereby authorizes and directs any such
                  subtenant to make payments of rent directly to Landlord upon
                  receipt of notice from Landlord. No direct collection by
                  Landlord from any subtenant will be construed to constitute a
                  novation or a release of Tenant from the further performance
                  of its obligations hereunder. Receipt by Landlord of rent from
                  any assignee, subtenant, or occupant of the Premises will not
                  be deemed a waiver of the covenants contained in this Lease or
                  a release of Tenant under the Lease. The receipt by Landlord
                  from any subtenant obligated to make payments of rent will be
                  a full and complete release, discharge, and acquittance to the
                  subtenant of its obligations to Tenant to the extent of any
                  such amount of rent so paid to Landlord. Landlord is
                  authorized and empowered, on behalf of Tenant to endorse the
                  name of Tenant upon any check, draft, or other instrument
                  payable to Tenant with respect to the Premises and evidencing
                  payment of rent, or any part thereof, and to receive and apply
                  the proceeds therefrom in accordance with the terms hereof.

         (3)      Landlord's consent to any sale, assignment, encumbrance,
                  subletting, occupation, lien, or other transfer shall not
                  release Tenant from any of Tenants obligations hereunder or be
                  deemed to be consent to any subsequent occurrence. Any sale,
                  assignment, encumbrance, subletting, occupation, lien or other
                  transfer of this Lease which does not comply with the
                  provisions of this Paragraph 11 shall be void.

         (4)      Any transfer of this Lease by merger, consolidation, or
                  liquidation or any change in ownership of or power to vote the
                  majority of outstanding voting stock of Tenant or, if Tenant
                  is a partnership, any withdrawal, replacement or substitution
                  of any partner or partners, either general or limited, shall
                  constitute an assignment whether the result of a single or
                  series of transactions, and shall be subject to Landlord's
                  approval under subparagraph 11 (a); provided, however, that
                  Landlord's approval shall not be required to any transfer of
                  this Lease by merger, consolidation, the sale of Tenant or any
                  portion thereof, a public offering, a change in the legal
                  structure of Tenant or any change in ownership of or power to
                  vote the majority of outstanding voting stock of Tenant,
                  whether the result of a single transaction or of a series of
                  transactions if following such transfer the net worth of
                  Tenant or its successor equals or exceeds the net worth of
                  Tenant immediately prior to such transfer (collectively,
                  "Permitted Transfers"). A Permitted Transfer shall not be
                  deemed a sublease, assignment or transfer of this Lease for
                  purposes of Special Stipulations 2 or 3 set forth on Exhibit
                  "G" hereto.

12.      INSURANCE AND INDEMNIFICATION

                                       14
<PAGE>   15

         (1)      Landlord shall not be liable to Tenant and Tenant hereby
                  waives all claims against Landlord and any of its partners for
                  any injury or damage to any person or property in or about the
                  Premises by or from any cause whatsoever, excepting Landlord's
                  gross negligence or willful acts, and, without limiting the
                  generality of the foregoing, whether caused by water leakage
                  of any character from the roof, walls, basement, or other
                  portion of the Premises or the Building, or caused by gas,
                  fire, Acts of God, discharge of sprinklers, excessive heat or
                  cold, sewage, odors, noise, bursting or leakage of pipes or
                  plumbing fixtures, riot, strike, court order, governmental
                  body or authority, other tenants, or explosion of the Building
                  or the complex of which it may be a part or any, part thereof.
                  Tenant will hold Landlord harmless from damages due to the
                  interruption of Tenant's business caused by any damage
                  whatsoever.

         (2)      Tenant shall hold Landlord harmless from and defend Landlord
                  against any and all claims or liability from any injury or
                  damage to any person or property whatever: (i) occurring in,
                  on, or about the Premises or any part thereof, and (ii)
                  occurring in, on, or about any facilities (including without
                  limitations, elevators, stairways, passageways or hallways),
                  the use of which Tenant may have in conjunction with other
                  tenants of the Building, when such injury or damage shall be
                  caused in part or in whole by the act, neglect, fault of, or
                  omission of any duty with respect to the same by Tenant, its
                  agents, servants, employees or any other person entering the
                  Premises with express or implied invitation of Tenant. Tenant
                  further agrees to indemnify and save harmless Landlord against
                  and from any and all claims by or on behalf of any person,
                  firm, or corporation, arising from the conduct or management
                  of any work or thing whatsoever done by Tenant in or about the
                  Premises, and will further indemnify and save Landlord
                  harmless against and from any and all claims arising from any
                  breach or default on the part of Tenant in the performance of
                  any covenant or agreement on the part of Tenant to be
                  performed pursuant to the terms of this Lease, or arising from
                  any act or negligence of Tenant, or any of its agents,
                  contractors, servants, employees or licensees and from and
                  against all costs, counsel fees, expenses and liabilities
                  incurred in connection with any such claim or action or
                  proceeding brought thereon. Landlord hereby indemnifies and
                  agrees to save Tenant harmless against any and all liability,
                  loss, cost, damage or expense, including without limitation
                  court costs and reasonable attorney's fees, imposed on Tenant
                  and caused by the negligence or willful misconduct of
                  Landlord, its employees, agents or contractors, or occurring
                  in connection with any default of Landlord hereunder. All
                  property in the Building or Premises belonging to Tenant, its
                  agents, employees, or invitees shall be there at the risk of
                  Tenant. Tenant agrees to indemnify and save harmless Landlord
                  against claims for damage to, theft, misappropriation, or loss
                  of said property unless said claims are caused directly or
                  indirectly through Landlord's gross negligence. Furthermore,
                  and subject to the proviso set forth in the immediately
                  preceding sentence with respect to Landlord's gross
                  negligence, in case any action or proceeding shall be brought
                  against Landlord by reason of any claims or liability, Tenant
                  agrees to defend such action or proceedings at Tenant's sole
                  expense by counsel reasonably satisfactory to Landlord. The
                  provisions of this Paragraph 12 shall survive the expiration
                  or termination of this Lease with respect to any claims or
                  liability occurring prior to such expiration or termination.

         (3)      Tenant agrees to purchase at its own expense and to keep in
                  force during the term of this Lease the following policies of
                  insurance: (i) worker's compensation/employer's liability
                  insurance with a limit of $1,000,000; (ii) commercial general
                  liability insurance in respect of the Premises and the conduct
                  or operation of business therein, including personal injury
                  and property damage, with contractual liability endorsement,
                  with a combined single limit of not less than Three Million
                  Dollars ($3,000,000.00); and (iii)

                                       15
<PAGE>   16

                  business auto liability insurance with a limit of $1,000,000
                  (stating any hired and non-owned autos, or any auto). Said
                  policies shall: (a) name Landlord as an additional insured and
                  insure Landlord's contingent liability under this Lease
                  (except for the worker's compensation policy, which shall
                  instead include a waiver of subrogation endorsement in favor
                  of Landlord), (b) be issued by an insurance company or
                  companies which is/are acceptable to Landlord and licensed to
                  do business in the State of Georgia, and (c) provide that said
                  insurance shall not be canceled unless thirty (30) days prior
                  written notice shall have been given to Landlord. Said policy
                  or policies or certificates thereof shall be delivered to
                  Landlord by Tenant upon commencement of the term of the Lease
                  and upon each renewal of said insurance. In addition, Landlord
                  may request a copy of any of the aforementioned insurance
                  policies not more than once per year. The purchase of such
                  insurance shall not release Tenant of any legal obligations
                  contained within this Lease.

13.      WAIVER OF SUBROGATION

         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 policies of insurance covering
such property, 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 that time and
in any event only with respect to loss or damage occurring during such times as
the releasor's 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 releasor 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 carriers 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.

                           that which is described on Exhibit "H" attached
                           hereto and by this reference made a part hereof),
                           including operation of building standard lighting and
                           general office machines of a type which require no
                           more than a 110 volt duplex outlet; and

                  (5)      security services during the times and in a manner
                           that such services are in Landlord's judgment
                           customarily furnished in comparable office buildings
                           in the immediate market area, including a security

                           comparable office buildings in the immediate market
                           area; and

                  (6)      All building standard fluorescent lighting. All
                           incandescent and nonstandard fluorescent lights shall
                           be maintained at Tenant's expense;

                  (7)      All temperature control devices and air diffusers;
                           and

                           hinges, and closers.

         The services described in items (2), (3), (4), (6) and (7) above shall
be furnished twenty-four (24) hours per day, seven (7) days per week, subject to
the provisions of subparagraph (f) of this Paragraph 14.

         (3)      For the purpose of this Lease, normal business hours ("Normal
                  Business Hours") shall be from 8:00 am. to 6:00 p.m. Monday
                  through Friday and from 8:00 am. to 1:00 p.m. on Saturday,
                  excluding holidays established by Landlord. Notwithstanding
                  the foregoing, Tenant shall have access to the Premises
                  twenty-four (24) hours per day, seven (7) days per week.

         (4)      Landlord shall provide additional or after hours heating or
                  air conditioning at Tenant's request upon at least twenty-four
                  (24) hours advance notice, and Tenant shall pay the building
                  standard charge for such services as determined from time to
                  time by Landlord. As of the date of this Lease, the building
                  standard charge for additional or after hours heating or air
                  conditioning is $50.00 per hour per floor of the Building (or
                  portion thereof if Tenant occupies less than a full floor),
                  with such rate being subject to change at Landlord's
                  discretion. The obligation hereunder to make such additional
                  utilities available will be subject to the rules and
                  regulations of any municipal or any other governmental
                  authority regulating the business of providing such utility
                  service. Tenant agrees to keep closed all window coverings, if
                  any, when necessary because of the sun's position, and Tenant
                  also agrees at all times to cooperate fully with Landlord and
                  to abide by all regulations and requirements which Landlord
                  may prescribe for the proper functioning and protection of
                  said heating, ventilating, and air conditioning system. Except
                  with respect to the Telecommunications Equipment, Tenant will
                  not, without the prior written consent of Landlord (which
                  consent shall not be unreasonably withheld or delayed), use
                  any heat generating equipment, machines, or excess lighting in
                  the Premises which affect the amount of energy required to
                  maintain the temperature

                                       17
<PAGE>   18

                  otherwise maintained by the heating, ventilating and air
                  conditioning system. In the event of such consent, Landlord
                  reserves the right to install supplementary air conditioning
                  equipment and the cost thereof, including the ongoing cost of
                  additional electricity, chilled water (if available), and/or
                  domestic water consumed as a result of the use of such
                  equipment, shall be paid by Tenant to Landlord upon demand.
                  The type, size and location of such supplemental air
                  conditioning equipment shall be determined or approved by
                  Landlord.

         (5)      Except with respect to the Telecommunications Equipment and
                  the Supplemental HVAC relating thereto (as more particularly
                  addressed in the Special Stipulations, including the
                  provisions of Paragraph 18 thereof requiring separate metering
                  for purposes of calculating Tenant's electrical usage in
                  excess of the Building standard), Tenant will not, without
                  written consent of Landlord, use within the Premises or the
                  Building any device or machine, in any number or combination
                  thereof or for any number of hours, which will in any way
                  cause Tenant to use electricity or water in excess of that
                  which Landlord has established as standard for the Building
                  for use of the Premises during Normal Business Hours for use
                  as general office space. Moreover, with respect to electrical
                  service (and except as contemplated by the first sentence of
                  this Paragraph), Tenant's use thereof shall not exceed, either
                  in voltage, rate of capacity, use beyond Normal Business
                  Hours, or overall load, that which Landlord deems to be
                  standard for the Building. For purposes hereof, "electrical
                  standard" for the Building is more fully described and
                  identified on Exhibit "H" attached hereto and by this
                  reference made a part hereof. Except as otherwise contemplated
                  by the provisions of Paragraphs 4, 5 and 10 of the Special
                  Stipulations, if Tenant in Landlord's judgment shall require
                  such additional water or electrical current, Tenant shall
                  first procure the consent of Landlord, which consent may not
                  be unreasonably withheld or delayed (and, if withheld with
                  respect to any request for additional electrical current,
                  shall be further governed by the provisions of Paragraph 10 of
                  the Special Stipulations), and Landlord may cause a special
                  meter to be installed so as to measure such additional
                  domestic water, chilled water (if available), or electrical
                  current. The cost of any such meters and of installation,
                  maintenance, and repair thereof shall be paid for by Tenant,
                  and Tenant agrees to pay Landlord or the utility company, as
                  the case may be, on demand, for the ongoing cost of
                  consumption of such additional water or electricity. In the
                  event that Landlord is responsible for reading the meter and
                  invoicing the Tenant, Landlord shall be entitled to charge the
                  Tenant the reasonable additional expenses for so doing.

         (6)      Landlord shall not be in default hereunder or be liable for
                  any damage directly or indirectly resulting from, nor shall
                  the rental herein reserved be abated by reason of, the (i)
                  installation, use, or interruption of use of any equipment in
                  connection with the furnishing of any of the foregoing
                  services or utilities, or the making of repairs or
                  improvements to the Premises or the Building, or (ii) failure
                  to furnish or delay in furnishing any such services or
                  utilities when such failure is caused by Acts of God or the
                  elements, strikes, governmental orders, accidents, or other
                  conditions beyond the reasonable control of the Landlord or by
                  the making of repairs or improvements to the Premises or to
                  the Building; unless, however, any matter described in the
                  foregoing Subparagraph (i) of this Subparagraph results from
                  the gross negligence or willful misconduct of Landlord, its
                  agents or employees, in which case Rent hereunder shall be
                  abated on a pro rata basis for any portion of the Premises
                  rendered untenantable as a result thereof should Building
                  services to the Premises (including, without limitation, water
                  and electricity serving the Premises) be interrupted for ten
                  (10) consecutive

                                       18
<PAGE>   19

                  Business days.

         (7)      It shall be Tenant's responsibility and expense to install,
                  move, maintain, adjust, and repair its property and fixtures,
                  including but not limited to, its: signage, pictures, bulletin
                  boards, plaques, furniture, above standard flooring, filing
                  cabinets, computer cables. computer equipment, business
                  machines, draperies, blinds, kitchen appliances, special water
                  heaters, kitchen cabinets, private restroom fixtures, special
                  air conditioning or power conditioning equipment, locks for
                  furniture and filing cabinets, paging systems, modular
                  furniture components (including task lighting. flat wiring,
                  and power distribution cables), combination locks, specialty
                  electrical devices, exhaust fans, fire extinguishers, carpet
                  squares, and/or other furniture, fixtures, or equipment
                  installed by Tenant, or which were supplied, specified, or
                  requested by Tenant and installed by Landlord.

         (8)      Any sums payable under this Paragraph shall be considered
                  additional rent and Landlord shall have the same remedies for
                  a default in payment of such sums as for a default in the
                  payment of rent.

         (9)      Tenant may contract for additional or supplemental janitorial
                  services to the Premises (at Tenant's sole cost and expense)
                  so long as Tenant uses the same janitorial service engaged by
                  Landlord from time to time and provides Landlord with a copy
                  of the separate agreement entered into with such janitorial
                  service describing the scope and nature of services to be
                  rendered within the Premises.

15.      ESTOPPEL CERTIFICATE

         Within ten (10) days following any written request which Landlord may
make from time to time, Tenant shall execute and deliver to Landlord a
certificate substantially in the form attached hereto as Exhibit "D" attached
hereto (as modified to accurately reflect the terms of this Lease) or in such is
the form as is reasonably requested by any mortgagee, beneficiary, purchaser or
prospective purchaser of the building or any interest thereon, indicating
thereon any exceptions thereto which may exist at that time. Failure of the
Tenant to execute and deliver such certificate shall constitute an acceptance of
the Premises and acknowledgment by Tenant that the statements included in
Exhibit "D" (as modified to accurately reflect the terms of this Lease) are true
and correct without exception.

<PAGE>   20

16.      HOLDING OVER

         Tenant will, at the termination of this Lease by lapse of time or
otherwise, yield up immediate possession to Landlord. If Tenant retains
possession of the Premises or any part thereof after such termination or if any
of Tenant's property remains which Landlord has previously requested be removed,
then Landlord may serve written notice upon Tenant that such holding over
constitutes either (i) creation of a month to month tenancy, upon the terms and
conditions set forth in this Lease, or (ii) creation of a tenancy at sufferance,
in any case upon the terms and conditions set forth in this Lease; provided,
however, that the monthly rental [or daily rental under (ii)] shall, in addition
to all other sums which are to be paid by Tenant hereunder, whether or not as
additional rent, be equal to one hundred fifty percent (150%) of the rental
being paid monthly to Landlord under this Lease immediately prior to such
termination [prorated in the case of (ii) on the basis of a 365 day year for
each day Tenant remains in possession]. If no such notice is served, then a
tenancy at sufferance shall be deemed to be created at the rent in the preceding
sentence. Tenant shall also pay to Landlord all damages sustained by Landlord
resulting from retention of possession by Tenant, including the loss of any
proposed subsequent tenant for any portion of the Premises. The provisions of
this paragraph shall not constitute a waiver by Landlord of any right of entry
as herein set forth; nor shall receipt of any rent or any other act in apparent
affirmance of the tenancy operate as a waiver of the right to terminate this
Lease for a breach of any of the terms, covenants, or obligations herein on
Tenant's part to be performed.

17.      SUBORDINATION

                                       20
<PAGE>   21

         So long as Tenant is not disturbed from possession of the Premises
unless and until Tenant has defaulted hereunder and all applicable notice, grace
and cure periods have expired, this Lease shall be subject and subordinate
(without the necessity of any additional document being executed by Tenant for
the purpose of effecting a subordination) at all times to: (a) all ground leases
or underlying leases which may now exist or hereafter be executed affecting the
Building, the Property, or any part thereof, and (b) the lien of any first
mortgage or deed to secure debt which may now exist or hereafter be executed in
any amount for which said Building, land, ground leases or underlying leases, or
Landlord's interest or estate in any of said items is specified as security,
together with all renewals, modifications, consolidations, participations,
replacements, and extensions of any such first mortgage or deed to secure debt.
Notwithstanding the foregoing, Landlord or the holder of any first mortgage or
deed to secure debt on the Building or the Property or any part thereof shall
have the right to subordinate or cause to be subordinated in whole or in part
any such ground leases or underlying leases or any such liens to this Lease (but
not in respect to priority of entitlement of insurance or condemnation
proceeds). In the event that any ground lease or underlying lease terminates for
any reason or any first mortgage or deed to secure debt is foreclosed or a
conveyance in lieu of foreclosure is made for any reason, Tenant shall,
notwithstanding any subordination, attorn to and become the Tenant of the
successor in interest to Landlord at the option of such successor in interest.
Tenant covenants and agrees to execute and deliver, upon demand by Landlord or
the holder of any first mortgage or deed to secure debt on the Building or the
Property or any part thereof and in the form requested by Landlord or the holder
of any first mortgage or deed to secure debt on the Building or the Property or
any part thereof, any additional documents evidencing the priority of
subordination of this Lease with respect to any such ground leases or underlying
leases or the lien of any such mortgage or deed to secure debt, provided,
however, that Tenant receives from the holder of such mortgage or deed to secure
debt an agreement in form reasonably satisfactory to Tenant and said holder
that, so long as Tenant is not in default under this Lease, Tenant shall not be
disturbed in its possession of the Premises, and that any action or proceeding
in lieu thereof will not result in the cancellation or termination of this
Lease, and that in the event of any such foreclosure or sale, this Lease shall
continue in full force and effect, as a direct lease between Tenant and the then
owner of the Premises upon all terms, covenants and conditions herein. Tenant
hereby irrevocably appoints Landlord as attorney-in-fact of Tenant to execute,
deliver, and record any such documents in the name and on behalf of Tenant so
long as such nondisturbance assurances are contained therein. Landlord hereby
represents and warrants that the Property is not presently encumbered by a
mortgage or deed to secure debt.

18.      RULES AND REGULATIONS

         Tenant shall faithfully observe and comply with the Rules and
Regulations. Landlord shall not be responsible for the nonperformance by any
other tenant or occupant of the Building of any of the Rules and Regulations.

19.      ENTRY BY LANDLORD

         Landlord reserves and shall at all times upon reasonable verbal notice
to Tenant (except in case of emergency) have the right to enter the Premises to
inspect the same to determine if Tenant is complying with all terms and
provisions of this Lease, to perform Tenant's obligations under this Lease in
accordance with Paragraph 25 hereof, to supply janitorial service and any other
service to be provided by Landlord to Tenant hereunder (it being understood that
Tenant may elect to contract directly for its own janitorial service with
Landlord's approved vendor in accordance with Section 14(i) hereof) and, with
reasonable prior notice, to show said Premises to prospective purchasers,
mortgagees or tenants, to post notices of nonresponsibility, and to alter,
improve, or repair the Premises and any portion of the Building of which the
Premises are a part or to which access is conveniently made through the
Premises, without abatement of rent and may for that purpose erect, use, and
maintain scaffolding, pipes, conduits, and other necessary structures in and
through the Premises where reasonably required by the character of

                                       21
<PAGE>   22

the work to be performed, provided that entrance to the Premises shall not be
blocked thereby, and further provided that the business of Tenant shall not be
interfered with unreasonably. In the case of any alteration, improvements or
repairs requiring access to or construction within the Fourth Floor Expansion
Premises, Landlord shall use reasonable efforts in designing such improvements
to avoid wherever possible the Fourth Floor Expansion Premises and, where
required, shall use reasonable efforts to minimize any impact on the Fourth
Floor Expansion Premises or any use by Tenant thereof. In connection with the
aforesaid and except for the gross negligence or willful misconduct of Landlord,
its agents or employees, Tenant hereby waives any claim for damages for any
injury or inconvenience to or interference with Tenant's business, any loss of
occupancy or quiet enjoyment of the Premises, and any other loss occasioned
thereby. For each of the aforesaid purposes, Tenant agrees that its doors shall
be keyed to Landlord's building standard master keying system and that Landlord
shall at all times have and retain master or pass keys with which to unlock all
of the doors in, upon, and about the Premises, and Landlord shall have the right
to use any and all means which Landlord may deem necessary or proper to open
said doors in an emergency, in order to obtain entry to any portion of the
Premises, and any entry to the Premises, or portions thereof obtained by
Landlord by any of said means, or otherwise, shall not under any circumstances
be construed or deemed to be a forcible or unlawful entry into, or a detainer
of, the Premises, or an eviction, actual or constructive, of Tenant from the
Premises or any portions thereof. Landlord shall also have the right at any
time, without the same constituting an actual or constructive eviction and
without incurring any liability to Tenant therefor, to change the arrangement
and/or location of entrances or passageways, doors and doorways and corridors,
elevators, stairs, toilets, or other public parts of the Building.

20.      INSOLVENCY OR BANKRUPTCY

         The appointment of a receiver to take possession of all or
substantially all of the assets of Tenant or an assignment of Tenant for the
benefit of creditors, or any action taken or suffered by Tenant under any
insolvency, bankruptcy, or reorganization act shall at Landlord's option
constitute a breach of this Lease by Tenant. In addition to other remedies for
default as set forth in Paragraph 21 hereof, upon the happening of any such
event or at any time thereafter, at Landlord's option, this Lease shall
terminate five (5) days after written notice of termination from Landlord to
Tenant. In no event shall this Lease be assigned or assignable by operation of
law or by voluntary or involuntary bankruptcy proceedings or otherwise and in no
event shall this Lease or any rights or privileges hereunder be an asset of
Tenant under any bankruptcy, insolvency, or reorganization proceedings.

21.      DEFAULT

         (1)      The following events shall be deemed to be events of default
                  by Tenant under this Lease:

                  (1)      Tenant shall fail to pay when or before due any sum
                           of money becoming due to be paid to Landlord
                           hereunder, whether such sum be any installment of the
                           Base Rent herein reserved, any other amount treated
                           as Rent hereunder, or any other payment or
                           reimbursement to Landlord required herein, whether or
                           not treated as additional Rent hereunder, and such
                           failure shall continue for a period of five (5)
                           business days from written notice from Landlord to
                           Tenant that such payment was due; provided, however,
                           that Landlord shall only be required to give such
                           written notice two (2) times in any twelve (12) month
                           period and any further failure by Tenant within such
                           twelve (12) month period to pay any such sum within
                           five (5) days of the date such payment is due shall
                           constitute an immediate default hereunder with no
                           requirement that Landlord give any such further
                           written notice; or

                  (2)      Tenant shall fail to comply with any term, provision,
                           or covenant of this Lease

                                       22
<PAGE>   23

                           other than by failing to pay when or before due any
                           sum of money becoming due to Landlord hereunder, and
                           shall not cure such failure within twenty (20) days
                           (forthwith, if the default involves a hazardous
                           condition) after written notice thereof to Tenant or,
                           in the event that any such cure is not capable of
                           being completed within such twenty (20) day period,
                           Tenant fails to commence its cure within such twenty
                           (20) day period or thereafter fails to pursue such
                           cure with diligence to completion within sixty (60)
                           days from the date of original receipt of written
                           notice of default; or

                  (3)      Tenant shall fail to vacate the Premises immediately
                           upon termination of this Lease, by lapse of time or
                           otherwise, or upon termination of Tenant's right to
                           possession only; or

                  (4)      The leasehold interest of Tenant shall be levied upon
                           under execution or be attached by process of law or
                           Tenant shall fail to contest diligently the validity
                           of any lien or claimed lien and give sufficient
                           security to Landlord to insure payment thereof or
                           shall fail to satisfy any judgment rendered thereon
                           and have the same released, and such default shall
                           continue for ten (10) days after written notice
                           thereof to Tenant; or

                  (5)      Tenant shall fail to perform any of its obligations
                           under any agreement with Landlord other than this
                           Lease and such failure shall continue for a period of
                           twenty (20) days after written notice from Landlord
                           to Tenant; or

                  (6)      Default by any Guarantor of this Lease of the terms
                           of its Guaranty, or the bankruptcy or insolvency of
                           any Guarantor.

         (2)      Upon the occurrence of any such events of default described in
                  this Paragraph or elsewhere in this Lease, Landlord shall have
                  the option to pursue any one or more of the following remedies
                  without any notice or demand whatsoever:

                  (1)      Landlord may, at its election, terminate this Lease
                           or terminate Tenant's right to possession only,
                           without terminating the Lease;

                  (2)      Upon any termination of this Lease, whether by lapse
                           of time or otherwise, or upon any termination of
                           Tenant's right to possession without termination of
                           the Lease, Tenant shall surrender possession and
                           vacate the Premises immediately and deliver
                           possession thereof to Landlord, and Tenant hereby
                           grants to Landlord full and free license to enter
                           into and upon the Premises in such event with or
                           without process of law and to repossess Landlord of
                           the Premises as of Landlord's former estate and to
                           expel or remove Tenant and any others who may be
                           occupying or within the Premises and to remove any
                           and all property therefrom, without being deemed in
                           any manner guilty of trespass, eviction, or forcible
                           entry or detainer, and without incurring any
                           liability for any damage resulting therefrom, Tenant
                           hereby waiving any right to claim damage for such
                           re-entry and expulsion, and without relinquishing
                           Landlord's right to rent or any other right given to
                           Landlord hereunder or by operation of law;

                  (3)      Upon termination of this Lease, whether by lapse of
                           time or otherwise, Landlord shall be entitled to
                           recover as damages, all Rent and other sums due and
                           payable by Tenant on the date of termination, plus
                           the sum of: (i) an amount equal to the then present
                           value of the entire amount of the Rent calculated
                           using a discount

                                       23
<PAGE>   24

                           rate equal to the average discount rate for auctioned
                           3-month Treasury Bills as of the date of termination
                           of this Lease, and other sums provided herein to be
                           paid by Tenant for the residue of the stated term
                           hereof, less the fair rental value of the Premises
                           for such residue (taking into account the time and
                           expense necessary to obtain a replacement tenant or
                           tenants, including expenses hereinafter described in
                           Paragraph 21(b)(4) relating to recovery of the
                           Premises, preparation for reletting and for reletting
                           itself), and (ii) the cost of performing any other
                           covenants which would have otherwise been performed
                           by Tenant.

                  (4)         (i) Upon any termination of Tenant' s right to
                           possession only without termination of the Lease,
                           Landlord may, at Landlord's option, enter into the
                           Premises, remove Tenant's signs and other evidences
                           of tenancy, and take and hold possession thereof as
                           provided in Paragraph 21(b)(2) above, without such
                           entry and possession terminating the Lease or
                           releasing Tenant in whole or in part from any
                           obligation, including Tenant's obligation to pay the
                           Rent, hereunder for the full term. In any such case,
                           Tenant shall pay forthwith to Landlord the Rent due
                           from month to month as same becomes due for the
                           residue of the stated term hereof plus any other sums
                           provided herein to be paid by Tenant,

                           (ii) Landlord shall use commercially reasonable
                  efforts to relet the Premises or any part thereof for such
                  Rent and upon such terms as Landlord in its sole discretion
                  shall determine (including the right to relet the Premises for
                  a greater or lesser term than that remaining under this Lease,
                  the right to relet the Premise as a part of a larger area, and
                  the right to change the character or use made of the Premises)
                  and Landlord shall not be required to accept any tenant
                  offered by Tenant or to observe any instructions given by
                  Tenant about such reletting. In any such case, Landlord may
                  make repairs, alterations and additions in or to the Premises,
                  and redecorate the same to the extent Landlord deems necessary
                  or desirable, and Tenant shall, upon demand, pay the cost
                  thereof, together with Landlord's expenses of reletting
                  including, without limitation, any broker's commission
                  incurred by Landlord. If the consideration collected by
                  Landlord upon any such reletting plus any sums previously
                  collected from Tenant are not sufficient to pay the full
                  amount of all Rent, together with the costs of any repairs,
                  alterations, additions, redecorating, and Landlord's expenses
                  of reletting and the collection of the rent accruing therefrom
                  (including reasonable attorney's fees and reasonable broker's
                  commissions,) Tenant shall pay to Landlord the amount of such
                  deficiency upon demand and Tenant agrees that Landlord may
                  file suit to recover any sums failing due under this section
                  from time to time;

                  (5)      Landlord may, at Landlord's option, enter into and
                           upon the Premises, with or without process of law, if
                           Landlord determines in its sole discretion that
                           Tenant is not acting within a commercially reasonable
                           time to maintain, repair, or replace anything for
                           which Tenant is responsible hereunder and correct the
                           same, without being deemed in any manner guilty of
                           trespass, eviction or forcible entry and detainer,
                           and without incurring any liability for any damage
                           resulting therefrom, and Tenant agrees to reimburse
                           Landlord, on demand, as additional Rent for any
                           expenses which Landlord may incur in thus effecting
                           compliance with Tenant's obligations under this
                           Lease;

                  (6)      Any and all property which may be removed from the
                           Premises by Landlord pursuant to the authority of the
                           Lease or by law, to which Tenant is or may be
                           entitled, may be handled, removed, and stored, as the
                           case may be, by or at the

                                       24
<PAGE>   25

                           direction of Landlord at the risk, cost and expense
                           of Tenant, and Landlord shall in no event be
                           responsible for the value, preservation, or
                           safekeeping thereof. Tenant shall pay to Landlord,
                           upon demand, any and all expenses incurred in such
                           removal and all storage charges against such property
                           so long as the same shall be in Landlord's possession
                           or under Landlord's control. Any such property of
                           Tenant not retaken by Tenant from storage within
                           thirty (30) days after removal from the Premises
                           shall, at Landlord's option, be deemed conveyed by
                           Tenant to Landlord under this Lease as by a bill of
                           sale without further payment or credit by Landlord to
                           Tenant.

         (3)      Pursuit of any of the foregoing remedies shall not preclude
                  pursuit of any of the other remedies herein provided or any
                  other remedies provided by law (all such remedies being
                  cumulative) nor shall pursuit of any remedy herein provided
                  constitute a forfeiture or waiver of any Rent due to Landlord
                  hereunder or any damages accruing to Landlord by reason of the
                  violation of any of the terms, provisions, and covenants
                  herein contained. No act or thing done by Landlord or its
                  agents during the term hereby granted shall be deemed a
                  termination of this Lease or an acceptance of the surrender of
                  the Premises, and no agreement to terminate this Lease or
                  accept a surrender of the Premises shall be valid unless in
                  writing signed by Landlord. Landlord's acceptance of the
                  payment of Rent or other payments hereunder after the
                  occurrence of an event of default shall not be construed as a
                  waiver of such default, unless Landlord so notifies Tenant in
                  writing. Forbearance by Landlord in enforcing one or more of
                  the remedies herein provided upon an event of default shall
                  not be deemed or constitute a waiver of such default or of
                  Landlord's right to enforce any such remedies with respect to
                  such default or any subsequent default. If, on account of any
                  breach or default by Tenant in Tenant's obligations under the
                  terms and conditions of this Lease, it shall become necessary
                  or appropriate for Landlord to employ or consult with an
                  attorney concerning or to enforce or defend any of Landlord's
                  rights or remedies hereunder, Tenant agrees to pay any
                  reasonable attorney's fees so incurred.

         (4)      Without limiting the foregoing, Tenant hereby appoints and
                  designates the Premises as a proper place for service of
                  process upon Tenant and agrees that service of process upon
                  any office manager or corporate officer of Tenant within the
                  Premises shall constitute personal service of such process
                  upon Tenant (provided, however, Landlord does not hereby waive
                  the right to serve Tenant with process by any other lawful
                  means) provided that a copy of such process is also mailed to
                  Tenant at the Premises by U.S. Certified Mail, and Tenant
                  hereby further expressly waives any right to trial by jury.

22.      DAMAGE BY FIRE, ETC.

         (1)      If the Building, improvements, or Premises are rendered
                  partially or wholly untenantable by fire or other casualty,
                  and if such damage cannot, in Landlord's reasonable
                  estimation, be materially restored within one hundred twenty
                  (120) days of such damage, then Landlord may, at its sole
                  option, terminate this Lease as of the date of such fire or
                  casualty. Landlord shall exercise its option provided herein
                  by written notice to Tenant within sixty (60) days of such
                  fire or other casualty. For purposes hereof, the Building,
                  improvements, or Premises shall be deemed "materially
                  restored" if they are in such condition as would not prevent
                  or materially interfere with Tenant's use of the Premises for
                  the purpose for which it was then being used.

         (2)      If this Lease is not terminated pursuant to Paragraph 22(a),
                  then Landlord shall proceed with all due diligence to repair
                  and restore the Building and the Premises, at Landlord's

                                       25
<PAGE>   26

                  cost, (except that Landlord may elect not to rebuild if such
                  damage occurs during the last year of the term exclusive of
                  any option which is unexercised at the date of such damage).
                  Any restoration of the Premises by Landlord shall not include
                  replacement of furniture, equipment or other items of Tenant's
                  property.

         (3)      If this Lease shall be terminated pursuant to this Paragraph
                  22(a), the term of this Lease shall end on the date of such
                  damage as if that date had been originally fixed in this Lease
                  for the expiration of the term hereof. If this Lease shall not
                  be terminated by Landlord pursuant to this Paragraph 22(a) and
                  in the event that Landlord should fail to complete such
                  repairs and material restoration within one hundred eighty
                  (180) days after the date of such damage, Tenant may, at its
                  option and as its sole remedy, terminate this Lease by
                  delivering written notice to Landlord, whereupon the Lease
                  shall end on the date of such notice as if the date of such
                  notice were the date originally fixed in this Lease for the
                  expiration of the term hereof, provided, however, that if
                  construction is delayed because of changes, deletions, or
                  additions in construction requested by Tenant, strikes,
                  lockouts, casualties, Acts of God, war, material or labor
                  shortages, governmental regulation or control or other causes
                  beyond the reasonable control of Landlord, the period for
                  restoration, repair or rebuilding shall be extended for the
                  amount of time Landlord is so delayed.

         (4)      Tenant agrees that during any period of restoration or repair
                  of the Premises, Tenant shall continue the operation of
                  Tenant's business within the Premises to the extent
                  practicable. During the period from the date of the damage or
                  the date all or a portion of the Premises is rendered
                  untenantable until the date that the untenantable portion of
                  the Premises is materially restored, the Rent shall be reduced
                  to the extent of the proportion of the Premises which is
                  untenantable, however, there shall be no abatement of other
                  sums to be paid by Tenant to Landlord as required by this
                  Lease.

         (5)      In no event shall Landlord be required to rebuild, repair or
                  replace any part of the partitions, fixtures, additions and
                  other improvements constructed or installed by Tenant pursuant
                  to the provisions of Paragraph 8 hereof or any of the
                  improvements constructed or installed by Tenant pursuant to
                  the terms of the Fourth Floor Expansion Premises Lease
                  Improvement Agreement. Landlord has the right but not the
                  obligation to rebuild, repair, or replace at Tenant's expense
                  so much of the partitions, fixtures, additions and other
                  improvements as may be necessary to ensure that the Premises
                  are materially restored. Any insurance which may be carried by
                  Landlord or Tenant against loss or damage to the Building or
                  Premises shall be for the sole benefit of the party carrying
                  such insurance and under its sole control except that
                  Landlords insurance may be subject to control by (i) the
                  holder or holders of any indebtedness secured by a mortgage or
                  deed to secure debt covering any interest of Landlord in the
                  Premises, the Building, or the Property, and/or (ii) the
                  ground lessor of the Property.

         (6)      Notwithstanding anything herein to the contrary, in the event
                  the holder of any indebtedness secured by a mortgage or deed
                  to secure debt covering the Premises, Building, or Property or
                  the ground lessor of the Property requests that any insurance
                  proceeds be paid to it, then Landlord shall have the right to
                  terminate the Lease by delivering written notice of
                  termination to Tenant within fifteen (15) days after such
                  requirement is made by any such person, whereupon the Lease
                  shall end on the date of such damage as if the date of such
                  damage were the date originally fixed in this Lease for the
                  expiration of the Lease Term.

         (7)      In the event of any damage or destruction to the Building or
                  the Premises by any peril

                                       26
<PAGE>   27

                  covered by the provisions of this Paragraph 22, Tenant shall,
                  upon notice from Landlord, remove forthwith, at its sole cost
                  and expense, all or such portion of the property belonging to
                  the Tenant or its licensees from all of the Building or the
                  Premises, or such portion, as Landlord shall request. Tenant
                  hereby indemnifies and holds Landlord harmless from any loss,
                  liability, costs, and expenses, including attorney's fees,
                  arising out of any claim or damage or injury as a result of
                  any alleged failure to secure the Premises properly prior to
                  such removal and/or during such removal, except for loss,
                  liability, cost or expense caused by the negligence of
                  Landlord, its agents or employees.

23.      CONDEMNATION

         (1)      If any substantial part of the Premises, Building or Property
                  should be taken for any public or quasi-public use under
                  governmental law, ordinance, or regulation, or by right of
                  eminent domain, or by private purchase in lieu thereof and the
                  taking would prevent or materially interfere with Tenant's
                  then existing Permitted Use of the Premises, this Lease shall
                  terminate effective when the physical taking shall occur in
                  the same manner as if the date of such taking were the date
                  originally fixed in this Lease for the expiration of the term
                  hereof.

         (2)      If part of the Premises, Building, or Property shall be taken
                  for any public or quasi-public use under any governmental law,
                  ordinance or regulation, or by right of eminent domain, or by
                  private purchase in lieu thereof, and this Lease is not
                  terminated as provided in Paragraph 23(a), this Lease shall
                  not terminate but the Rent payable hereunder during the
                  unexpired portion of this Lease shall be reduced to such
                  extent, if any, as may be fair and reasonable under all of the
                  circumstances, and Landlord shall undertake to restore the
                  Building and Premises to a condition suitable for Tenant's
                  use, as near to the condition thereof prior to such taking as
                  is reasonably feasible under all circumstances.

         (3)      Tenants shall not share in any condemnation award or payment
                  in lieu thereof or in any award for damages resulting from any
                  grade change of adjacent streets, the same being hereby
                  assigned to Landlord by Tenant; provided, however, that Tenant
                  may separately claim and receive from the condemning
                  authority, if legally payable, compensation for Tenant's
                  removal and relocation costs and for Tenant's loss of business
                  and/or business interruption, except that no such claim shall
                  diminish or otherwise adversely affect Landlord's award or the
                  awards of any and all ground and underlying lessors and
                  mortgages.

         (4)      Notwithstanding anything to the contrary contained in this
                  Paragraph 23, if the temporary use or occupancy of any part of
                  the Premises shall be taken or appropriated under power of
                  eminent domain during the term of this Lease, this Lease shall
                  be and remain unaffected by such taking or appropriation and
                  Tenant shall continue to pay in full all Rent payable
                  hereunder by Tenant during the term of this Lease. In the
                  event of any such temporary appropriation or taking, Tenant
                  shall be entitled to receive that portion of any award which
                  represents compensation for the use of or occupancy of the
                  Premises during the term of this Lease, and Landlord shall be
                  entitled to receive that portion of any award which represents
                  the cost of restoration of the Premises and the use and
                  occupancy of the Premises after the end of the Lease Term.

24.      SALE BY LANDLORD

         The covenants and obligations of Landlord hereunder shall be binding
upon the Landlord named herein and its successors and assigns, only with respect
to their respective periods of time as Landlord hereunder. In the event of a
sale or conveyance by Landlord of the Building, the same shall operate to
release Landlord from any future liability upon any of the covenants or
conditions, express or implied, herein contained in favor of Tenant, and in such
event Tenant agrees to look solely to the successor in interest of Landlord in
and to this Lease. Tenant agrees to attorn to the purchaser or assignee in any
such sale.

25.      RIGHT OF LANDLORD TO PERFORM

         All covenants and agreements to be performed by the Tenant under any of
the terms of this Lease shall be performed by Tenant at Tenant's sole cost and
expense and without any abatement of Rent except as expressly provided herein.
If the Tenant shall fail to pay any sum of money, other than Rent, required to
be paid by it hereunder or shall fail to perform any other act on its part to be
performed hereunder, and such failure shall continue for ten (10) days after
notice thereof by the Landlord, the Landlord may, but shall not be obligated so
to do, and without waiving or releasing the Tenant from any obligations of the
Tenant, make any such payment or perform any such act on the Tenant's part to be
made or performed as in this Lease provided. All sums so paid by the Landlord
and all necessary incidental costs, together with interest thereon at the Agreed
Interest Rate from the date of such payments by the Landlord, shall be payable
as additional Rent to the Landlord on demand, and the Tenant covenants to pay
any such sums, and the Landlord shall have, in addition to any other right or
remedy of the Landlord, the same rights and remedies in the event of nonpayment
thereof by the Tenant as in the case of default by the Tenant in the payment of
the Rent.

26.      SURRENDER OF PREMISES

         (1)      At the end of the term or any renewal thereof or other sooner
                  termination of this Lease, the Tenant will peaceably deliver
                  up to the Landlord possession of the Premises, together with
                  all improvements or additions (other than improvements
                  specifically authorized or required to be removed by Tenant
                  pursuant to the terms of this Lease and the Special
                  Stipulations attached hereto) upon or belonging to the same,
                  by whomsoever made, in the same condition as received, or
                  first installed, reasonable wear and tear, damage by fire,
                  earthquake, Act of God, or the elements alone excepted. Tenant
                  may, upon the termination of this Lease, remove all movable
                  furniture and equipment belonging to Tenant, at Tenant's sole
                  cost, repairing any damage caused by such removal. Property
                  not so removed shall be deemed abandoned by the Tenant, and
                  title to the same shall thereupon pass to Landlord. Upon
                  request by Landlord, unless otherwise agreed to in writing by
                  Landlord, Tenant shall remove, at Tenant's sole cost, any or
                  all permanent improvements or additions to the Premises
                  installed by or at the expense of Tenant and all movable
                  furniture and equipment belonging to Tenant which may be left
                  by Tenant and repair any damage resulting from such removal.

         (2)      The voluntary or other surrender of this Lease by Tenant, or a
                  mutual cancellation thereof, shall not work a merger, and
                  shall, at the option of the Landlord, either terminate all or
                  any existing subleases or subtenancies, or operate as an
                  assignment to Landlord of any or all such subleases or
                  subtenancies.

<PAGE>   29

27.      WAIVER

         If either Landlord or Tenant waives the performance of any term,
covenant or condition contained in this Lease, such waiver shall not be deemed
to be a waiver of any subsequent break or nonperformance of the same or any
other term, covenant, or condition contained herein. Furthermore, the acceptance
of Rent by Landlord shall not constitute a waiver of any preceding breach by
Tenant of any term, covenant or condition of this Lease, regardless of
Landlord's knowledge of such preceding breach at the time Landlord accepted such
Rent. Failure by Landlord to enforce any of the terms, covenants, or conditions
of this Lease for any length of time shall not be deemed to waive or to decrease
the right of Landlord to insist thereafter upon strict performance by Tenant.
Waiver by Landlord of any term, covenant, or condition contained in this Lease
may only be made by a written document signed by Landlord.

28.      NOTICES

         All notices and demands which may or are required to be given by either
party to the other hereunder shall be in writing and shall be deemed given when
delivered or mailed as required below. All notices and demands by one party to
the other shall be either delivered to the Premises or sent by a commercial
interstate courier service offering proof of delivery or by United States
Certified or Registered mail, postage and fees prepaid. Notices and demands by
Landlord to Tenant shall be addressed to the Tenant at the Premises in care of
Mr. Ken Gavranovic, with a copy to Alon Panovka, Esq., 5064 Roswell Road, Suite
D-101, Atlanta, Georgia 30342, or to such other place as the Tenant may from
time to time designate in a notice to the Landlord. Notices and demands by
Tenant to the Landlord shall be addressed to the Landlord at Landlord's Address,
or to such other firm or to such other place as Landlord may from time to time
designate in a notice to the Tenant. If requested by Landlord, Tenant shall send
copies of any notices and demands by Tenant to the holder or holders of any
mortgage or deed to secure debt on the Property or any part thereof.

29.      CERTAIN RIGHTS RESERVED TO THE LANDLORD

         The Landlord may enter upon the Premises and/or may exercise any or all
of the following rights hereby reserved without being deemed guilty of an
eviction or disturbance of the Tenant's use or possession and without being
liable in any manner to the Tenant and without abatement of Rent or affecting
any of the Tenant's obligations hereunder:

         (1)      To change the name or street address of the Building;

         (2)      To install and maintain a sign or signs on the exterior of the
                  Building;

         (5)      To grant to anyone the exclusive right to conduct any
                  particular business or undertaking in the Building; provided,
                  however, that the granting of any such exclusive rights shall
                  in no way limit or restrict Tenant's right to use and enjoy
                  the Premises or the rights expressly granted to Tenant under
                  this Lease;

                                       29
<PAGE>   30

         (6)      To close the Building after regular working hours and on the
                  legal or nationally observed holidays subject, however, to
                  Tenants right of admittance, under such reasonable regulations
                  as Landlord may prescribe from time to time, which may
                  include, by way of example but not of limitation, that persons
                  entering or leaving the Building identify themselves to a
                  watchman by registration or otherwise and that said persons
                  establish their right to enter or leave the Building; and

         (7)      To take any and all measures, including inspections, repairs,
                  alterations, decorations, additions, and improvements to the
                  Premises or the Building, and identification and admittance
                  procedures for access to the Building as may be necessary or
                  desirable for the safety, protection, preservation or security
                  of the Premises or the Building or the Landlord's interests,
                  or as Landlord may deem necessary or desirable in the
                  operation of the Building.

30.      ABANDONMENT

         If Tenant shall be dispossessed by process of law, or otherwise, any
personal property belonging to Tenant and left on the Premises shall, at the
option of Landlord, be deemed to be abandoned and title thereto shall thereupon
pass to Landlord, in addition to other remedies available to Landlord for
Tenants defaults under this Lease.

31.      SUCCESSORS AND ASSIGNS

         Subject to the provisions of Paragraph 11 hereof, the terms, covenants,
and conditions contained herein shall be binding upon and inure to the benefit
of the heirs, successors, executors, administrators, and assigns of the parties
hereto.

32.      ATTORNEY'S FEES

         In the event that any action or proceeding is brought to enforce any
term, covenant, or condition of this Lease on the part of Landlord or Tenant,
the prevailing party in such litigation shall be entitled to reasonable
attorney's fees to be fixed by the court in such action or proceeding.

33.      SECURITY DEPOSIT

                                       30
<PAGE>   31

         (1)      Tenant shall pay to Landlord upon execution of this Lease a
                  Security Deposit in the amount of $372,227.00 for the faithful
                  performance of all terms, covenants, and conditions of this
                  Lease. Tenant agrees that Landlord may apply said Security
                  Deposit to remedy any failure by Tenant to repair or maintain
                  the Premises or to perform any other terms, covenants, and
                  conditions contained herein. If Tenant has kept and performed
                  all terms, covenants, and conditions of this Lease during the
                  term hereof and the Security Deposit has not been applied to
                  Rent as provided below in this Paragraph, Landlord will on the
                  termination hereof, promptly return said sum to Tenant or the
                  last permitted assignee of Tenant's interest hereunder at the
                  expiration of the Lease term. Should Landlord use any portion
                  of said sum to cure any default by Tenant hereunder, Tenant
                  shall forthwith replenish said sum to such original amount.
                  Landlord shall not be required to keep the Security Deposit
                  separate from its general funds. Tenant shall be entitled to
                  interest on any such deposit in an amount equal to one-half of
                  the interest accruing thereon from time to time. Landlord
                  shall deposit the Security Deposit in a money market account
                  with such depository as Landlord and Tenant may mutually agree
                  upon from time to time. Tenant's share of interest on the
                  Security Deposit shall accrue and be added to the Security
                  Deposit, and shall be disbursed from time to time at the time
                  and in the manner the Security Deposit is disbursed in
                  accordance with the terms of this Paragraph. Landlord's share
                  of such interest shall be paid to Landlord from time to time
                  as Landlord may direct and shall be retained by Landlord (not
                  as security, but for its own account) in consideration for the
                  execution of this Lease and the administration of the account
                  in which the Security Deposit is deposited. Upon the
                  occurrence of any events of default described in Paragraph 21
                  of this Lease (subject to any applicable notice, grace and
                  cure periods), the Security Deposit shall become due and
                  payable to Landlord for application of the proceeds thereof
                  against Tenant's obligations hereunder in such manner as
                  Landlord may direct.

         (2)      Subject to other terms and conditions contained in this Lease,
                  if the Building is conveyed by Landlord voluntarily or
                  involuntarily, said Security Deposit shall be turned over to
                  (or credited to the account of) the Landlord's grantee or
                  successor and, if so, Tenant hereby releases Landlord from any
                  and all liability with respect to said deposit and its
                  application or return. Should Landlord fail or refuse to so
                  transfer or credit any voluntary or involuntary transferee of
                  the Property with the Security Deposit (or any portion of the
                  Security Deposit then held by Landlord), Tenant shall
                  nonetheless be entitled to a credit against Rent accruing from
                  time to time hereunder (in the amount of any such undisbursed
                  portion of the Security Deposit so held by Landlord) at the
                  time and in the manner the Security Deposit is required to be
                  applied toward payment of Rent under this Paragraph, until
                  such Security Deposit is so applied in full.

         (3)      A portion of the Security Deposit in the amount of $279,170.00
                  (the "Principal Deposit") shall be held by Landlord as
                  hereinabove provided until such time as Tenant has established
                  to the reasonable satisfaction of Landlord that Tenant has (i)
                  actually received $10,000,000.00 or more in cash from the
                  issuance and sale of stock in Tenant as a result of one or
                  more public offerings in a recognized stock exchange, or
                  through the private placement and sale of stock in Tenant, and
                  (ii) taking into account receipt of such $10,000,000.00 in
                  cash, Tenant has a net worth of not less than $10,000,000.00
                  according to generally accepted accounting principles
                  consistently applied. At such time as Tenant has satisfied
                  each of the foregoing conditions (but not otherwise), Landlord
                  shall thereafter apply the Principal Deposit against Rent and
                  other charges due and payable under this Lease at the time the
                  same become due and payable hereunder. At such time as the
                  Principal Deposit has been fully applied against Rent or other
                  obligations of Tenant hereunder, Tenant shall resume payment
                  of Rent and such other

                                       31
<PAGE>   32

                  charges at the time and in the manner the same become due and
                  payable as contemplated by the terms and conditions of this
                  Lease.

         (4)      The remaining portion of the Security Deposit (other than the
                  Principal Deposit) in the amount of $93,057.00 (the
                  "Additional Deposit") shall be held by Landlord as hereinabove
                  provided until the third anniversary of the Commencement Date,
                  at which time Landlord shall apply the Additional Deposit
                  against Rent and other charges due and payable under the Lease
                  at the time the same become due and payable hereunder so long
                  as no event of default has occurred and is continuing under
                  this Lease. In addition, in the event that the conditions
                  described in the foregoing subparagraphs 33(c)(i) and (ii) are
                  satisfied as a result of the issuance and sale of stock in
                  Tenant in connection with one or more initial public offerings
                  in a recognized stock exchange (but not from the private sale
                  of stock pursuant to a private placement memorandum, or
                  otherwise) on or before the third anniversary of the
                  Commencement Date, Landlord shall thereafter apply the
                  Additional Deposit against Rent and other charges due and
                  payable under this Lease at the time the same become due and
                  payable hereunder. If, and only if, at the time Landlord is
                  required under this subparagraph to apply the Additional
                  Deposit against Rent or other Tenant obligations Landlord is
                  at the same time then required to apply the Principal Deposit
                  against such obligations (or vice versa, as the case may be),
                  Landlord is nonetheless authorized and directed to hold the
                  Additional Deposit and apply the same against Rent and other
                  obligations at such time as the Principal Deposit has been
                  fully applied thereto. At such time as the Additional Deposit
                  has been fully applied against Rent or other obligations of
                  Tenant hereunder, Tenant shall resume payment of Rent and such
                  other charges at the time and in the manner the same become
                  due and payable as contemplated by the terms and conditions of
                  this Lease.

34.      FINANCIAL STATEMENTS

         Within ten (10) days following Landlord's request therefor, Tenant
shall provide to Landlord copies of (a) if available, the most recent fiscal
year financial statements for Tenant and any Guarantors of this Lease, as
audited by a certified public accountant, and (b) the most recent fiscal quarter
financial statements for Tenant and any Guarantors of this Lease, as certified,
respectively, by Tenant and each such Guarantor. The financial statements shall
include, but not necessarily be limited to, a balance sheet, statements of
income and retained earnings, and a statement of source and uses of funds. All
such statements shall be prepared in accordance with the generally accepted
accounting principles.

35.      TENANT AUTHORITY

         If Tenant signs as a corporation or partnership, each of the persons
executing this Lease on behalf of Tenant does hereby covenant and warrant that
Tenant is a duly authorized and existing corporation or partnership, as the case
may be, that Tenant has and is qualified to do business in Georgia, that the
corporation or partnership has full right and authority to enter into this
Lease, and that each and all of the persons signing on behalf of the corporation
or partnership are authorized to do so. Upon Landlord's request, Tenant shall
provide Landlord with evidence reasonably satisfactory to Landlord confirming
the foregoing covenants and warranties.

36.      MORTGAGEE AND GROUND LESSOR APPROVALS

         The approval or consent of Landlord shall not be deemed to have been
unreasonably withheld for purposes of any provisions of this Lease requiring
such consent if any mortgagee (which shall include the holder of any deed to
secure debt ) of the Premises, Building, or Property or any portion thereof, or
the ground lessor of the Property, shall refuse or withhold its approval or
consent thereto. Any requirement of Landlord pursuant to this Lease which is
imposed pursuant to the direction of any such mortgagee or ground lessor shall
be deemed to have been reasonably imposed by Landlord if made in good faith.

37.      MISCELLANEOUS

         (1)      Time is of the essence of this Lease and all of its
                  provisions. Periods of time expressed in days for performance,
                  unless otherwise specified, shall mean calendar days.

         (2)      This Lease shall in all respects be governed by the laws of
                  the State of Georgia.

         (3)      This Lease, together with its exhibits, contains all the
                  agreements of the parties hereto and supersedes any previous
                  negotiations. There have been no representations made by the
                  Landlord or any representative or agent of Landlord, or
                  understandings made between the parties other than those set
                  forth in this Lease and its exhibits. This Lease may not be
                  modified except by a written instrument by the parties hereto.

         (4)      All obligations of Tenant hereunder not fully performed as of
                  the expiration or earlier termination of the term of this
                  Lease shall survive the expiration or earlier termination of
                  the term hereof.

         (5)      If any clause, phrase, provision, or portion of this Lease or
                  the application thereof to any person or circumstance shall be
                  invalid or unenforceable under applicable law, such event
                  shall not affect, impair, or render invalid or unenforceable
                  the remainder of this Lease or any other clause, phrase,
                  provision or portion hereof, nor shall it affect the
                  application of any other clause, phrase, provision, or portion
                  hereof to other persons or circumstances, and it is also the
                  intention of the parties to this Lease that in lieu of each
                  such clause, phrase, provision, or portion of this Lease that
                  is invalid or unenforceable, there be added as a part of this
                  Lease contract a clause, phrase, provision or portion as
                  similar in terms to such invalid or unenforceable clause,
                  phrase, provision or portion as may be possible and be valid
                  and enforceable.

         (6)      Whenever a period of time is herein described for action to be
                  taken by Landlord, the Landlord shall not be liable or
                  responsible for, and there shall be excluded from the
                  computation for any such period of time, any delays due to
                  causes of any kind whatsoever which are beyond the control of
                  Landlord.

         (7)      Notwithstanding any other provision of this Lease to the
                  contrary, if the Commencement Date hereof shall not have
                  occurred before twelve (12) months following the date hereof,
                  this Lease shall be null and void and neither party shall have
                  any liability or obligation to the other hereunder. The
                  purpose and intent of this provision is to avoid the
                  application of the rule against perpetuities to this Lease.

         (8)      Anything contained in the foregoing provisions of this section
                  to the contrary notwithstanding, neither Tenant nor any other
                  person having an interest in the possession, use, occupancy,
                  or utilization of the Premises shall enter into any lease,

                                       33
<PAGE>   34

                  sublease, license, concession, 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 from the Premises leased,
                  used, occupied or utilized (other than an amount based on a
                  fixed percentage or percentages of receipts of sales), and any
                  such proposed lease, sublease, license, concession, or other
                  agreement shall be absolutely void and ineffective as a
                  conveyance of any right of interest in the possession, use,
                  occupancy, or utilization of any part of the Premises.

38.      LANDLORD'S LIEN'S

         (1)      In addition to any statutory lien for Rent in Landlord's
                  favor, Landlord shall have and Tenant hereby grants to
                  Landlord a continuing security interest for all rentals and
                  other sums of money becoming due hereafter from Tenant, upon
                  all goods, wares, equipment, fixtures, furniture, inventory,
                  accounts, contract rights, chattel paper, and other personal
                  property of Tenant situated on the Premises, and following any
                  Tenant default such property shall not be removed therefrom
                  without the consent of Landlord until all arrearages in Rent
                  as well as any and all other sums of money then due to
                  Landlord hereunder shall first have been paid and discharged.
                  So long as Tenant is not in default under this Lease beyond
                  any applicable notice, grace or cure period hereunder,
                  Landlord shall agree to subordinate its security interest
                  contained herein in favor of security interests granted by
                  Tenant for purposes of financing personal property located
                  within the Premises.

         (2)      In the event of a default under this Lease, Landlord shall
                  have, in addition to any other remedies provided herein or by
                  law, all rights and remedies under the Uniform Commercial
                  Code, including without limitation the right to sell the
                  property described in this Paragraph 38 at public or private
                  sale upon five (5) days' notice to Tenant. Tenant hereby
                  agrees that this Lease shall constitute a security agreement
                  and further agrees to execute such financing statements and
                  other instruments necessary or desirable in Landlord's
                  discretion to perfect the security interest hereby created.
                  Any statutory lien for Rent is not hereby waived, the express
                  contractual lien herein granted being in addition and
                  supplementary thereto.

39.      QUIET ENJOYMENT

         Landlord represents and warrants that it has full right and authority
to enter into this Lease and that Tenant, while paying the rental and performing
its other covenants and agreements herein set forth, shall peaceably and quietly
have, hold, and enjoy the Premises for the term hereof without hindrance or
molestation from Landlord or any party claiming by, through or under Landlord,
and Landlord shall defend Tenant's quiet enjoyment of the Premises, subject to
the terms and provisions of this Lease. In the event this Lease is a sublease,
then Tenant agrees to take the Premises subject to the provisions of the prior
leases. Landlord shall not be liable for any interference or disturbance by
other tenants or third persons, nor shall Tenant be released from any of the
obligations of this Lease because of such interference or disturbance.

40.      LANDLORD'S LIABILITY

         Any liability of Landlord hereunder shall be enforceable only out of
Landlord's interest in the Building or Property and in no event out of the
separate assets of any constituent partner of Landlord. 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.

<PAGE>   35

41.      NO ESTATE

         This contract shall create the relationship of Landlord and Tenant, and
no estate shall pass out of Landlord. Tenant has only a usufruct, not subject to
levy and sale and not assignable by Tenant, except as provided for herein and in
compliance herewith.

42.      [INTENTIONALLY OMITTED]

43.      LEASE EFFECTIVE DATE

         Submission of this instrument for examination or signature by Tenant
does not constitute a reservation of or option for lease, and it is not
effective as a lease or otherwise until execution by both Landlord and Tenant.

44.      HAZARDOUS MATERIALS

         Tenant shall not cause or permit the escape, disposal, or release of
any biologically or chemically active or other hazardous substances or materials
in, on, or about the Premises. Neither Tenant nor Landlord shall allow the
storage or use of such substances or materials in, on, or about the Premises in
any manner not sanctioned by law or by the highest standards prevailing in the
industry for the storage and use of such substances or materials, nor allow to
be brought into the Premises any such materials or substances except to use in
the ordinary course of Tenant's business, and then only after written notice has
been given to Landlord of the identity of such substances or materials
excepting, however, ordinary office and cleaning supplies. Without limitation,
hazardous substances and materials shall include those described in the
Comprehensive Environmental Response, Compensation and Liability Act of 1980, as
amended, 42 U.S.C. Section 9601 et seq., the Resource Conservation and Recovery
Act, as amended, 42 U.S.C. Section 6901 et seq., any applicable state or local
laws and the regulations adopted under these acts. If any lender or governmental
agency shall ever require testing to ascertain whether or not there has been any
release of hazardous materials in, on, or about the Premises, then the
reasonable costs thereof shall be reimbursed by Tenant to Landlord upon demand
as additional charges if such requirement applies to Tenant's use and occupancy
of 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 substances or materials
introduced by Tenant on the Premises. In all events, Tenant shall indemnify
Landlord in the manner elsewhere provided in this Lease from any release of
hazardous materials in, on, or about the Premises occurring while Tenant is in
possession, or elsewhere if caused by Tenant or persons acting under Tenant. The
within covenants shall survive the expiration or earlier termination of the
Lease term.

45.      BROKERAGE PROVISIONS.

         Landlord and Tenant represent and warrant that no broker, commission
agent, real estate agent or salesperson other than Broker has participated in
the negotiation of this Lease, its procurement or the procurement of Landlord or
Tenant. Landlord's Broker has represented Landlord in this transaction and shall
be paid a commission by Landlord pursuant to a separate, written agreement.
Tenant's Broker has represented Tenant in this transaction and shall be paid a
commission by Landlord pursuant to a separate, written agreement. Landlord and
Tenant hereby acknowledge and agree that no person, firm, corporation or entity
other than Broker is or shall be entitled to the payment of any fee, commission,

Landlord shall and does hereby indemnify and agree to hold Tenant harmless from
and against any claims, demands, actions and judgments of any and all brokers,
agents and other intermediaries alleging a commission, fee or other payment to
be owing by reason of Landlord's dealings, negotiations or communications in
connection with this Lease or the demise of the Premises. Likewise, Tenant shall
and does hereby indemnify and agree to hold Landlord harmless from and against
any claims, demands, actions and judgments of any and all brokers (other than
Broker), agents and other intermediaries alleging a commission, fee or other
payment to be owing by reason of Tenant's dealings, negotiations or
communications in connection with this Lease or the demise of the Premises. The
terms of this Paragraph 45 shall survive the expiration or other termination of
this Lease.

46.      HEALTH/FITNESS FACILITY

         Landlord and Tenant acknowledge and agree that Landlord has constructed
and operates in the Project a health and fitness facility (the "Health/Fitness
Facility"), and that the cost of maintaining and operating the Health/Fitness
Facility shall be included as a part of Operating Costs. If at any time during
the term of this Lease Landlord makes membership in the Health/Fitness Facility
available to tenants of the Project for a fee such that the membership fees
collected are sufficient to cover the expense of operating and maintaining the
Health/Fitness Facility, then such operation and maintenance costs shall not be
included as part of Operating Costs. In addition, only the amount by which the
operating and maintenance expenses of the Health/Fitness Facility exceed the
revenues derived therefrom shall be included in Operating Costs. In any event,
Landlord shall at all times have the right to require, as a condition to access
to the Health/Fitness Facility, that each individual entering the Health/Fitness
Facility sign an appropriate form documenting a waiver of claims against
Landlord and the operator of the Health/Fitness Facility.

48.      PREPAID BASE RENT

         Landlord has received a prepayment of Base Rent from Tenant in the
amount of $97,953.94 with respect to the Initial Premises. Such Base Rent
Prepayment shall be applied to Base Rent payments due from Tenant under the
Lease, commencing on the Commencement Date and on the first day of each
succeeding month thereafter until exhausted, at which time Tenant shall resume
making payments of Base Rent to Landlord as set forth in Paragraph 5 hereof. In
the event that the remaining portion of such prepaid Base Rent is insufficient
to pay the full amount of Base Rent due to Landlord in any month, Tenant shall
pay the remainder upon the due date thereof.

                              RULES AND REGULATIONS

1.       Sidewalks, halls, passages, exits, entrances, elevators and stairways
         shall not be obstructed by tenants or used by them for any purpose
         other than for ingress to and egress from their respective premises.
         The halls, passages, exits, entrances, elevators, escalators and
         stairways are not intended for the use of the general public and
         Landlord shall in all cases retain the right to control and prevent
         access thereto by all persons whose presence, in the judgment of
         Landlord, shall be prejudicial to the safety, character, reputation and
         interests of the Building and its tenants, provided that nothing herein
         contained shall be construed to prevent such access to persons with
         whom any tenant normally deals in the ordinary course of such tenant's
         business unless such persons are engaged in illegal activities. No
         tenant, and no employees or invitees of any tenant, shall go upon the
         roof of the Building, except as authorized by Landlord or as permitted
         by the provisions of the Special Stipulations governing access thereto
         and the use thereof.

2.       No sign, placard, picture, name, advertisement or notice, visible from
         the exterior of the premises shall be inscribed, painted, affixed,
         installed or otherwise displayed by any tenant either on its premises
         or any part of the Building without the prior written consent of
         Landlord, and Landlord shall have the right to remove any such sign,
         placard, picture, name, advertisement, or notice without notice to and
         at the expense of that tenant.

         If Landlord shall have given such consent to any tenant at any time,
         whether before or after the execution of the lease, such consent shall
         in no way operate as a waiver or release of any of the provisions
         hereof or of such lease, and shall be deemed to relate only to the
         particular sign, placard, picture, name, advertisement or notice so
         consented to by Landlord and shall not be construed as dispensing with
         the necessity of obtaining the specific written consent of Landlord
         with respect to any other such sign, placard, picture, name,
         advertisement or notice.

         All approved signs or lettering on doors and walls shall be printed,
         painted, affixed or inscribed at the expense of the tenant by a person
         approved by Landlord.

3.       The bulletin board or directory of the Building will be provided
         exclusively for the display of the name and location of tenants only
         and Landlord reserves the right to exclude any other names therefrom.

4.       No curtains, draperies, blinds, shutters, shades, screens or other
         coverings, awnings, hangings or decorations shall be attached to, hung,
         or placed in or used in connection with, any window or door on the
         premises of any tenant without the prior written consent of Landlord.
         In any event and with the prior written consent of Landlord, all such
         items shall be installed in such a manner that they shall in no way be
         visible from the exterior of the Building. No articles shall be placed
         or kept on the window sills so as to be visible from the exterior of
         the Building. No articles shall be placed against glass partitions or
         doors which might appear unsightly from outside the premises of any
         tenant.

         If Landlord shall determine that articles located in any tenant's
         premises can be seen through any glass partitions or doors between the
         Premises and any common areas of the Building and that such articles
         are placed or arranged in an unsightly manner, Landlord may install
         tinting or frosting on such glass partitions or doors.

5.       Landlord reserves the right to exclude from the Building between the
         hours of 6 p.m. and 8 a.m. Monday through Friday, and at all hours on
         Saturdays, Sundays, and holidays all persons who

                                   EXHIBIT "A"
                                   Page 1 of 6
<PAGE>   40

         are not tenants or their accompanied guests in the Building. Each
         tenant shall be responsible for all persons which it allows to enter
         the Building and shall be liable to Landlord for all acts of such
         persons.

         Landlord shall in no case be liable for damages for error with regard
         to the admission to or exclusion from the Building of any person other
         than actual damages arising by reason of Landlord's gross negligence or
         willful misconduct.

         During the continuance of any invasion, mob, riot, public excitement or
         other circumstance rendering such action advisable in Landlord's
         reasonable, good faith opinion, Landlord reserves the right to prevent
         access to the Building by closing the doors, or otherwise, for the
         safety of tenants and protection of the Building and property in the
         Building.

6.       No tenant shall employ any person or persons other than the janitor or
         Landlord for the purpose of cleaning the Premises unless otherwise
         agreed to by Landlord in writing. Except with the written consent of
         Landlord, no person or persons other than those approved by Landlord
         shall be permitted to enter the Building for the purpose of cleaning
         the same. No tenant shall cause any unnecessary labor by reason of such
         tenant's carelessness or indifference in the preservation of good order
         and cleanliness of the premises. Landlord shall in no way be
         responsible to any tenant for any loss of property on the premises,
         however occurring, or for any damage done to the effects of any tenant
         by the janitor or any other employee or any other person unless such
         loss or damage arises by reason of Landlord's gross negligence.
         Landlord shall not be responsible for the preservation of good order
         and cleanliness of the premises when the premises are occupied after
         Normal Business Hours.

7.       Each tenant shall see that all doors of its premises are closed and
         securely locked and must observe strict care and caution that all water
         faucets and other utilities that are not being used by Tenant while
         such premises are closed shall be carefully shut off, so as to prevent
         waste or damage, and for any default or carelessness the tenant shall
         make good all injuries sustained by other tenants or occupants of the
         Building. On multiple-tenancy floors, all tenants shall keep the door
         or doors to the Building corridors closed at all times except for
         ingress and egress.

8.       Each tenant shall not waste electricity, water or air conditioning and
         agrees to cooperate fully with Landlord to assure the most effective
         operation of the Building's heating and air conditioning, and shall
         refrain from attempting to adjust any controls except for minor
         adjustments to such controls for purposes of keeping the temperature of
         the interior of the Premises within the range normally customary for
         comparable Premises in the Atlanta metropolitan area. Each tenant shall
         keep window coverings in its premises closed when the effect of
         sunlight or cold weather would impose unnecessary loads on the
         Building's heating or air conditioning systems.

9.       Only one key or key-card for each office in the premises shall be
         furnished to tenant without charge. Additional keys are available at a
         charge of $3.00 each; additional key-cards are available at a charge of
         $7.00 each. No additional lock, latch, key-card or bolt of any kind
         shall be placed upon any door nor shall any changes be made in existing
         locks, key-cards or mechanisms thereof without written consent of
         Landlord, which consent shall not be unreasonably withheld, conditioned
         or delayed. If Landlord shall give its consent to a change in existing
         locks, then tenant shall in each case furnish Landlord with the key,
         key-card, or other appropriate mechanism for any such lock. At the
         termination of the Lease, tenant shall return to Landlord all keys,
         key-cards, or other mechanisms furnished to tenant by Landlord, or
         otherwise procured by Tenant, and in the event of loss of any such
         items so furnished, Tenant shall pay to Landlord the cost thereof.

<PAGE>   41

10.      No tenant shall make or have made additional copies of any keys or
         access devices provided by Landlord. Each tenant, upon the termination
         of the tenancy, shall deliver to Landlord all keys or access devices
         for the Building, offices, rooms and toilet rooms which shall have been
         furnished to the tenant or which the tenant shall have made. In the
         event of the loss of any keys or access devices so furnished by
         Landlord, tenant shall pay Landlord therefor.

11.      The toilet rooms, toilets, urinals, wash bowls, and other apparatus
         shall not be used for any purpose other than that for which they were
         constructed and no foreign substance of any kind whatsoever, including
         coffee grounds, shall be thrown therein, and the expense of any
         breakage, stoppage or damages resulting from violation of this rule
         shall be borne by the tenant who, or whose employees or invitees, shall
         have caused it.

12.      Except in connection with Tenant's use and operation of the Generator
         and/or the Supplemental HVAC system, as more particularly discussed in
         the Special Stipulations, no tenant shall use or keep on its premises
         or the Building any kerosene, gasoline or inflammable or combustible
         fluid or material. Except for such Supplemental HVAC System, no tenant
         shall use any method of heating or air conditioning other than that
         supplied by Landlord.

13.      Smoking is not permitted anywhere in the Building, or along the
         Building grounds or in any parking facilities, except for in such
         areas, if any, as shall be designated by Landlord from time to time.

14.      No tenant shall use, keep or permit to be used or kept in its premises
         any foul or noxious gas or substance or permit or suffer such premises
         to be occupied or used in a manner offensive or objectionable to
         Landlord or other occupants of the Building by reason of noise, odors
         and/or vibrations or interfere in any way with other tenants or those
         having business therein, nor shall any birds or animals other than
         seeing eye dogs and like animals be brought or kept in or about any
         premises of the Building.

15.      No cooking shall be done or permitted by any tenant on its premises
         except for cooking from which there are no strong or offensive odors in
         standardized non-commercial microwave ovens (except that use by the
         tenant of Underwriter's Laboratory approved equipment for the
         preparation of coffee, tea, hot chocolate and similar beverages for
         tenants and their employees shall be permitted, provided that such
         equipment and use is in accordance with all applicable federal, state,
         and city laws, codes, ordinances, rules and regulations) nor shall its
         premises be used for lodging.

16.      Except with the prior written consent of Landlord, no tenant shall sell
         or permit the sale, at retail, of newspapers, magazines, periodicals,
         theater tickets or any other goods or merchandise in or on its
         premises, nor shall tenant carry on, or permit or allow any employee or
         other person to carry on, the business of stenography, typewriting,
         printing, photocopying or any similar business in or from its premises
         for the service or accommodation of occupants of any other portion of
         the Building, nor shall its premises be used for the storage of
         merchandise or for manufacturing of any kind, or the business of a
         public barber shop, beauty parlor, nor shall its premises be used for
         any improper, immoral or objectionable purpose, or any business
         activity other than that specifically provided for in that tenant's
         lease.

17.      If tenant requires telegraphic, telephonic, burglar alarm or similar
         services, it shall first obtain, and comply with, Landlord's reasonable
         instructions for their installation. No tenant shall operate any
         television, radio, recorder or sound system in such a manner as to
         cause a nuisance to any other tenant of the Building.

                                   EXHIBIT "A"
                                   Page 3 of 6
<PAGE>   42

18.      Landlord will act reasonably in directing electricians as to where and
         how telephone, telegraph and electrical wires are to be introduced or
         installed. No boring or cutting for wires will be allowed without the
         prior written consent of Landlord. The location of burglar alarms,
         telephones, call boxes and other office equipment affixed to the
         premises shall be subject to the written approval of Landlord, which
         approval shall not be unreasonably withheld or delayed.

19.      Except as otherwise provided in the Special Stipulations, no tenant
         shall install any radio or television antenna, loudspeaker or any other
         device on the exterior walls or the roof of the Building. No tenant
         shall interfere with radio or television broadcasting or reception from
         or in the Building or elsewhere.

20.      No tenant shall lay linoleum, tile, carpet or any other floor covering
         so that the same shall be affixed to the floor of its premises in any
         manner except as approved in writing by Landlord. The expense of
         repairing any damage resulting from a violation of this rule or the
         removal of any floor covering shall be borne by the tenant by whom, or
         by whose contractors, employees or invitees, the damage shall have been
         caused.

21.      No furniture, freight, equipment, materials, supplies, packages,
         merchandise, or other property will be received in the Building or
         carried up or down the elevators except between such hours and in such
         elevators as shall be reasonably designated by Landlord. Landlord,
         acting reasonably, shall have the right to prescribe the weight, size
         and position of all safes, furniture, files, bookcases or other heavy
         equipment brought into the Building. Safes or other heavy objects
         shall, if considered necessary by Landlord, stand on wood strips of
         such thickness as determined by Landlord to be necessary to distribute
         properly the weight thereof. Landlord will not be responsible for loss
         of or damage to any such safe, equipment or property from any cause,
         and all damage done to the Building by moving or maintaining any such
         safe, equipment or other property shall be repaired at the expense of
         the responsible tenant.

         Business machines and mechanical equipment belonging to any tenant
         which cause noise or vibration that may be transmitted to the structure
         of the Building or to any space therein to such a degree as to be
         objectionable to Landlord or to any tenants in the Building shall be
         placed and maintained by tenant, at tenants expense, on vibration
         eliminators or other devices sufficient to eliminate noise or
         vibration. The persons employed to move such equipment in or out of the
         Building must be acceptable to Landlord (acting reasonably) and must
         carry appropriate amounts of liability and worker's compensation
         insurance. Upon Landlord's request, Landlord shall be named as
         additional insured under such person's liability insurance policy, and
         Landlord may require proof of insurance in the form of a certificate of
         insurance.

22.      All movement in or out of the Building of furniture or office
         equipment, or dispatch or receipt by tenants of any bulky material,
         merchandise or materials which requires the use of elevators or
         stairways, or movement through the Building entrances or lobby shall be
         under the supervision of Landlord and in the manner agreed between the
         tenant and Landlord by prearrangement before the performance as set
         forth in the Tenant Move-In Rules and Regulations attached hereto as
         Exhibit "A-1" and by this reference incorporated herein. Such
         prearrangement initiated by Tenant will include the determination by
         Landlord, and as to the time, method, and routing of movements and as
         to limitations for safety and or other concern which may prohibit any
         article, equipment or any other item from being brought into the
         Building. Tenant assumes all risks as to the damage to articles moved
         and injury to persons or public engaged or not engaged in such
         movement, including equipment, property and personnel of Landlord if
         damaged or injured as a result of acts in connection with carrying out
         this service for a tenant from the time of entering the Building to
         completion of work. All damages done to the Building by the
         installation or

                                   EXHIBIT "A"
                                   Page 4 of 6
<PAGE>   43

         removal of any property of a tenant or done by a tenant's property
         while in the Building, shall be repaired at the expense of such tenant.

23.      No tenant shall place a load upon any floor of its premises which
         exceeds the load per square foot which such floor was designed (or
         redesigned and retrofitted with Landlord's permission) to carry and
         which is allowed by law. Without Landlord's consent, which consent
         shall not be unreasonably withheld, conditioned or delayed, no tenant
         shall mark, or drive nails (other than to hang pictures), screw or
         drill into, the partitions, woodwork or plaster or in any way deface
         its premises or any part thereof.

24.      No tenant shall install, maintain or operate upon its premises any
         vending machines without the written consent of Landlord.

25.      There shall not be used in any space, or in the public areas of the
         Building, either by any tenant or others, any hand trucks except those
         equipped with rubber tires and side guards or other such
         material-handling equipment as Landlord may approve. No other vehicles
         of any kind shall be brought by any tenant into or kept in or about its
         premises.

26.      Each tenant shall store all of its trash and garbage within the
         interior of its premises. No material shall be placed in the trash
         boxes or receptacles if such material is of such nature that it may not
         be disposed of in the ordinary and customary manner of removing and
         disposing of trash and garbage in the city without violation of any law
         or ordinance governing such disposal. All trash, garbage and refuse
         disposal shall be made only through entryways and elevators provided
         for such purposes and at such times as Landlord shall designate.

27.      Canvassing, soliciting, distribution of handbills or any other written
         materials, and peddling in the Building are prohibited and each tenant
         shall cooperate to prevent the same. No tenant shall make room-to-room
         solicitation of business from other tenants in the Building.

28.      Landlord reserves the right to exclude or expel from the Building any
         person who, in Landlord's judgment, is intoxicated or under the
         influence of liquor or drugs or who is in violation of any of the Rules
         and Regulations of the Building.

29.      Without the prior written consent of Landlord, no tenant shall use the
         name of the Building in connection with or in promoting or advertising
         the business of such tenant except as that tenant's address.

30.      Each tenant shall comply with all energy conservation, safety, fire
         protection and evacuation procedures and regulations established by any
         governmental agency, and all reasonable rules, regulations and
         procedures established therefor by Landlord.

31.      Tenant assumes any and all responsibility for protecting its premises
         from theft, robbery and pilferage, which includes keeping doors locked
         and other means of entry to the premises closed.

32.      The requirements of each tenant will be attended to only upon
         application at the office of the Building by an authorized individual.
         Employees of Landlord shall not perform any work or do anything outside
         of their regular duties unless under special instructions from
         Landlord, and no employees will admit any person (tenant or otherwise)
         to any office without specific instructions from Landlord.

33.      No waiver by Landlord of any one or more of these Rules and Regulations
         for the benefit of any particular tenant shall be construed as a waiver
         of such Rules and Regulations in favor of any

         other tenant or tenants, nor prevent Landlord from thereafter enforcing
         any such Rules and Regulations against any or all tenants of the
         Building.

34.      Landlord reserves the right to make such other reasonable rules and
         regulations as in its judgment may from time to time be needed for
         safety and security, for care and cleanliness of the Building and for
         the preservation of good order therein, and to apply such rules and
         regulations uniformly to all tenants of the Building. Each tenant

         and any additional reasonable rules and regulations which are adopted.

35.      All wallpaper or vinyl fabric materials which any tenant may install on
         painted walls shall be applied with a strippable adhesives. The use of
         nonstrippable adhesives will cause damage to the walls when materials
         are removed and repairs made necessary thereby shall be made by
         Landlord at that tenant's expense.

36.      Each tenant will refer all contractors, contractors' representatives
         and installation technicians, rendering any service to such tenant, to
         Landlord's reasonable supervision, approval, and control before
         performance of any contractual service. This provision shall apply to
         all work performed in the Building, including installations of
         telephones, telegraph equipment, electrical devices and attachments and
         installations of any nature affecting floors, walls, woodwork, trim,
         windows, ceilings, equipment or any other physical portion of the
         Building.

37.      Each tenant shall give prompt notice to Landlord of any accidents to or
         defects in plumbing, electrical fixtures, or heating apparatus so that
         such accidents or defects may be attended to promptly.

38.      Each tenant shall be responsible for the observance of all of the
         foregoing Rules and Regulations by its employees, agents, clients,
         customers, invitees and guests.

39.      These Rules and Regulations are in addition to, and shall not be
         construed to in any way modify, alter or amend, in whole or in part,
         the terms, covenants, agreements and conditions of any lease of any
         premises in the Building.

49.      Landlord, Tenant's representative responsible for coordinating the
         move, and Tenant's furniture installation company, delivery company,
         moving company and related vendors involved in the move shall meet no
         less than fifteen (15) days prior to Tenant's scheduled move-in date to
         coordinate times, establish methods of delivery and reserve use of the
         loading docks, service corridors, elevators and stairwells for the
         move. There will be no charge for the right to reserve or use the
         loading docks, service corridors, elevators and stairwells for the
         move.

50.      Tenant's moving contractor will provide Landlord with a certificate of
         insurance evidencing coverage of workmen's compensation insurance
         affording applicable statutory coverage, and containing required
         statutory limits.

51.      All companies making deliveries in connection with the move are to
         adhere to the moving rules and regulations pertaining to the protection
         of the Premises and the Building. All costs associated with adhering to
         such protection procedures shall be the responsibility of the Tenant
         and/or Tenant's freight, moving or delivery company.

         (1)      Protection should be installed the evening prior to the move
                  and removed immediately upon completion. Tenant (or its moving
                  company) is responsible for leaving the area in as clean a
                  condition as it was prior to the move.

         (2)      The Building floor covering must be protected with masonite or
                  plywood along the prescribed route of movement through the
                  Building, as outlined by Landlord.

         (3)      The elevator lobbies, Building corridors and doors must be
                  protected with cardboard, plywood or other materials
                  pre-approved by Landlord.

         (4)      The elevator and entrance door frames must be protected with
                  2' x 4' boards at 90 degree angles taped to said door frames.

         (5)      The elevator cab walls and flooring must be protected with
                  masonite, plywood or soft pads.

         (6)      The movement of materials, furniture, etc. is limited only to
                  those corridors stairwells, elevators and service areas
                  designated by Landlord.

52.      It is the Tenant's responsibility to notify Landlord of items to be
         moved which are unusually large or heavy (in excess of 3,500 pounds) or
         which may require review by Landlord. Any large items that cannot be
         placed in the service elevator will require special hoisting
         arrangements which will be made through the Landlord. Tenant's moving
         contractor should include in the bid price to the Tenant any additional
         charges required for extra services which may need to be provided by
         the elevator contractor to hoist large items.

53.      Access control personnel will be notified as to the move-in schedule
         and will monitor the progress of the move. Any changes in the move-in
         schedule must be reported to Landlord or

         be required by the access control personnel for the moving contractor's
         supervisor and for the Tenant's representative responsible for
         coordinating the move.

54.      Landlord specifically reserves the right to modify any of these move-in
         rules and regulations and to establish such additional reasonable rules
         and regulations as in its reasonable judgment shall from time-to-time
         be required for the safety, protection, care and cleanliness of the
         Building, the operation thereof, the preservation and good order
         therein or the protection and comfort of the other tenants of the
         building and their agents, employees and guest.

                       PRIMARY LEASE IMPROVEMENT AGREEMENT

55.      GENERALLY

         Landlord and Tenant acknowledge and agree that this Primary Lease
Improvement Agreement shall govern the terms and conditions on which Tenant
Improvements shall be constructed and installed in the Initial Premises and the
Third Floor Expansion Premises, as the case may be. The text of each of the
following paragraphs has been prepared specifically with reference to the
Initial Premises and, except as hereinafter provided, shall also apply in each
and every respect to the buildout of the Third Floor Expansion Premises.
Wherever the context so requires, any reference in this Primary Lease
Improvement Agreement to Tenant Improvements, Plans, Landlord's Work and
Tenant's Cost shall apply mutatis mutandis to the construction of Tenant
Improvements in the Third Floor Expansion Premises, with the following
exceptions. Landlord's Allowance for construction of Tenant Improvements shall
be $12.00 per rentable square foot with respect to the Third Floor Expansion
Premises. In addition, Landlord has not agreed to provide any additional other
tenant improvement allowance or so-called "Additional Allowance" (other than as
set forth in the immediately preceding sentence) to Tenant for purposes of
funding the cost of Tenant Improvements in the Third Floor Expansion Premises.
Moreover, in no event and under no circumstances shall the cap applied to
payment by Tenant of Tenant's Cost under subparagraph 4(b), below, apply in any
respect whatsoever to Tenant's obligation to pay for Tenant's Cost of Tenant
Improvements to the Third Floor Expansion Premises. In the event that the cost
of the Tenant Improvements for the Third Floor Expansion Premises is less than
Landlord's Allowance therefor (the "Remaining Allowance"), Tenant shall have the
right to apply any such Remaining Allowance toward payment of Tenant's Cost of
Tenant Improvements for the Fourth Floor Expansion Premises. Any portion of the
Remaining Allowance shall be disbursed by Landlord to Tenant upon satisfaction
of each and every condition set forth in subparagraph 2(c) of the Fourth Floor
Expansion Premises Lease Improvement Agreement.

56.      IMPROVEMENTS

         (1)      At Tenant's expense, Landlord shall furnish and install
                  substantially in accordance with the construction drawings and
                  specifications approved by Tenant and Landlord, partitions,
                  doors, lighting fixtures, acoustical ceiling, floor coverings,
                  electrical outlets, telephone outlets, air conditioning, fire
                  sprinklers, signage, wall finishes, and construction clean-up
                  and other improvements required by Tenant which are normally
                  performed by the construction trades (the "Tenant
                  Improvements"). Landlord shall cause to be prepared at
                  Tenant's expense all architectural plans and specifications,
                  and all structural, mechanical and electrical engineering
                  plans and specifications (the "Plans") required for Tenant's
                  occupancy. The preparation of the Plans shall not include
                  selection of non-building standard finishes, or any fixtures
                  or furniture, or any other elements of interior design.

         (2)      At Landlord's expense, Landlord shall or has provided the
                  improvements described in Exhibit "C-3" attached hereto and by
                  this reference incorporated herein (hereinafter referred to as
                  "Landlord's Work").

         (3)      Landlord shall provide a construction management team that
                  will supervise and facilitate construction of all Tenant
                  Improvements. Such construction management team shall receive
                  a management fee in an amount equal to five percent (5%) of
                  all costs associated with the Tenant Improvements (including
                  any portion relating to "Tenant's Cost"(as

                                   EXHIBIT "C"
                                  Page 1 of 4
<PAGE>   51

                  hereinafter defined)). Such construction management fee shall
                  be paid to Landlord's construction manager as a disbursement
                  from "Landlord's Allowance" (as defined below).

         (1)

57.      LANDLORD'S ALLOWANCE

         As Landlord's contribution to work provided in Paragraph 1(a), Landlord
shall provide Tenant with an allowance of Two Hundred Eight Thousand Four
Hundred Fifty-Two and 00/100 Dollars ($208,452.00) ("Landlord's Allowance") with
respect to the Initial Premises. Notwithstanding the above, Tenant may, at
Tenant's discretion, use all or any portion of Landlord's Allowance for costs
related to design and construction of the Tenant Improvements, Tenant's signage
costs, moving expenses and installation of Tenant's furniture; provided,
however, that as a condition to Tenant's right to use Landlord's Allowance for
such purposes, Tenant shall be required to improve and finish all portions of
the Initial Premises to at least the following minimum standards: (i) a fully
completed ceiling with lights connected and switched and ceiling tiles
installed; (ii) the base building heating, ventilating and air conditioning
system installed, including interior duct work, supply grills, and interior zone
controls; (iii) sprinkler heads installed or relocated in accordance with
applicable codes; (iv) a fully operational and certified life safety system
installed; (v) finished floors; (vi) all drywall surfaces fully skimmed, sanded,
painted and finished; (vii) standard electrical distribution outlets for
convenience power installed and connected; and (viii) a certificate of occupancy
from the appropriate governmental authority shall be issued for such space.
Landlord represents and warrants to Tenant that implementation of the Plans will
(i) exceed the minimum standards set forth in the immediately preceding
sentence, and (ii) result in the completion of all improvements called for in
the pricing drawings approved by Landlord and Tenant.

[THE FOLLOWING PARAGRAPH APPLIES ONLY TO CONSTRUCTION OF TENANT IMPROVEMENTS IN
THE INITIAL PREMISES, AND NOT OTHERWISE]

         In addition to the Landlord's Allowance described above, Landlord
agrees to provide Tenant with an additional allowance with respect to
construction of Tenant Improvements in the Initial Premises up to the amount of
Forty-Nine Thousand Five Hundred Twenty-Two and 26/100 Dollars ($49,522.26),
which allowance is hereinafter referred to as the "Additional Allowance." Tenant
shall pay interest on the Additional Allowance in advance for the twelve month
period beginning on the Commencement Date at a rate of fifteen percent (15%) per
annum in the amount of up to Seven Thousand Four Hundred Twenty-Eight and 34/100
Dollars ($7,428.34), as follows: (i) the sum of Six Thousand Eight Hundred Four
and 83/100 Dollars ($6,804.83) shall be paid by Tenant to Landlord upon the full
execution and delivery of this Lease, and (ii) the balance of interest on the
Additional Allowance due to Landlord for the twelve month period beginning on
the Commencement Date, up to a maximum Six Hundred Twenty-Three and 51/100
dollars ($623.51), shall be paid by Tenant to Landlord upon demand. Upon the
first anniversary of the Commencement Date, Tenant shall elect either to (1)
repay to Landlord the full amount of the Additional Allowance, or (2) amortize
the Additional Allowance on a straight-line basis with interest at the rate of
fifteen percent (15%) per annum over the remainder of the Lease Term. In such
event, Tenant may prepay to Landlord all or any portion of the Additional
Allowance at any time and from time to time. Any such payments made by Tenant
shall be additional rent and shall, at Landlord's option, be paid as and when
Tenant's installments of Base Rent become due.

58.      TENANT'S COST

         (1)      Tenant shall bear the cost, if any, of the Tenant's
                  Improvements over and above the Landlord's Allowance and the
                  Additional Allowance (with respect to only the Initial
                  Premises)(such additional cost is hereinafter referred to as
                  "Tenant's Cost"). The cost of any modifications of any part of
                  the work described in Paragraph 1 already completed that are
                  requested by Tenant shall constitute part of Tenant's Cost. In
                  addition, subject to Landlord's approval (which approval shall
                  not be unreasonably withheld or delayed), Tenant may install
                  additional air conditioning units in the Initial Premises.

         (2)      Notwithstanding subparagraph (a) of this Paragraph 3 to the
                  contrary, Landlord agrees that Landlord shall be solely
                  responsible for and shall bear all cost and expenses incurred
                  in connection with the repairs, renovations and improvements
                  to the Initial Premises made in accordance with the Plans as
                  approved by Tenant in excess of $263,817.56; provided however,
                  that Tenant shall pay for all costs associated with any
                  Tenant-requested changes or modifications of the improvements
                  as defined by the Plans in Paragraph 1 of this Exhibit "C"
                  after the Plans have been approved by Tenant. Tenant will be
                  liable for any increase in construction costs if Tenant causes
                  a Tenant Delay.

         (3)      Tenant shall pay one-half (1/2) of all amounts payable by
                  Tenant to Landlord pursuant to this Paragraph 4 of this
                  Exhibit "C" immediately following Tenant's approval of the
                  price to be paid to Landlord as per subparagraph 5(b) hereof.
                  Tenant shall pay the remaining amounts immediately upon the
                  Commencement Date of the Lease (or, in the case of the Third
                  Floor Expansion Premises, upon the Third Floor Expansion
                  Effective Date).

59.      PLANNING SCHEDULE

         (1)      Preparation and Approval of Plans:

                  (1)      Landlord and Tenant shall diligently pursue the
                           preparation of the Plans in accordance with Exhibits
                           "C-1" and "C-2", as the case may be. Failure of
                           Tenant to provide said instructions by the dates
                           specified in Exhibits "C-1" and "C-2", as the case
                           may be, shall constitute a Tenant Delay.

                  (2)      The Plans shall then be prepared in conformance with
                           Landlord's requirements and all applicable codes,
                           ordinances and laws, and shall specify materials and
                           details equal to or better than Landlord's building
                           standard. The Plans shall be subject to approval of
                           Landlord and the government officials having
                           jurisdiction. Landlord shall submit complete
                           construction plans to Tenant for approval and Tenant
                           shall approve said Plans in accordance with Exhibits
                           "C-1" and "C-2", as the case may be. Failure of
                           Tenant to approve the Plans in accordance with
                           Exhibits "C-1" and "C-2", as the case may be, shall
                           constitute a Tenant Delay.

         (2)      Upon receipt of the approved Plans, Landlord shall provide a
                  quotation based upon competitively bid subcontract pricing for
                  the work to Tenant for approval as the price to be paid by
                  Tenant to Landlord for Tenant's Cost. Upon written approval of
                  such price by Tenant, Landlord and Tenant shall be deemed to
                  have given final approval to the Plans as the basis on which
                  the quotation was made, and Landlord shall be authorized to
                  proceed with the improvements to the Initial Premises in
                  accordance with such Plans. Tenant will not unreasonably
                  withhold its approval of such price. Failure of Tenant to

                                   EXHIBIT "C"
                                   Page 3 of 4
<PAGE>   53

                  approve or disapprove such price in accordance with Exhibits
                  "C-1" and "C-2", as the case may be, or unreasonable
                  disapproval of such price, shall constitute a delay by Tenant
                  in accordance with the provisions of Paragraph 4(b) of the
                  Lease. Landlord shall not be obligated to proceed with any
                  improvements of the Initial Premises until such time as Tenant
                  approves a price for the Tenant's Cost. Exhibits "C-1" and
                  "C-2", as the case may be, provide the intermediate actions
                  required of both Landlord and Tenant to satisfy the schedule
                  hereof.

         (3)      Any delays caused by Tenant's revision or change orders to the
                  approved Plans shall not constitute a delay by Tenant in
                  accordance with the provisions of Paragraph 4(b) of this Lease
                  with respect to the Initial Premises so long as such revisions
                  or change orders are solely and reasonably related to Tenant's
                  election to expand the size of the Initial Premises from
                  12,917 rentable square feet, as originally contemplated by
                  Landlord and Tenant, to the present size of 17,371 rentable
                  square feet. Landlord hereby agrees that Tenant may occupy any
                  portion of the Initial Premises as same becomes ready for
                  Tenant's occupancy notwithstanding that the entire Initial
                  Premises is not ready for Tenant's occupancy at such time.

60.      TENANT'S WORK

         All work not within the scope of the normal construction trades
employed in the Building, including, but not limited to, furnishing and
installing of telephones, furniture, and office equipment shall be furnished and
installed by Tenant at Tenant's expense. Tenant shall adopt a schedule in
conformance with the schedule of Landlord's contractors and conduct its work in
such a manner as to maintain harmonious labor relations and as not to interfere
unreasonably with or delay the work of Landlord's contractors. Tenant's
contractors and subcontractors shall be acceptable to and approved by Landlord
and shall be subject to the administrative supervision of Landlord. Contractors
and subcontractors engaged by Tenant shall employ persons and means to insure so
far as may be possible the progress of the work without interruption on account
of strikes, work stoppages or similar causes for delay. Landlord shall give
access and entry to the Premises to Tenant and its contractors and
subcontractors and reasonable opportunity and time and reasonable use of
facilities to enable Tenant to adapt the Premises for Tenant's use; provided,
however, that if such entry is prior to the Commencement Date or the Third Floor
Expansion Effective Date, as the case may be, such entry shall be subject to all
the terms and conditions of the Lease, except the payment of Rent.

                  Seventeen Thousand Two Hundred Sixty and 00/100 Dollars
                  ($217,260.00) with respect to the Fourth Floor Expansion

                  Landlord acknowledge and agree that at Tenant's option (and
                  subject to the Fourth Floor Expansion Plans), Tenant shall
                  have the right to utilize an exposed ceiling in any or all
                  areas of the Fourth Floor Expansion Premises in lieu of
                  ceiling grid and ceiling tile. Any such election by Tenant
                  must be noted on the Fourth Floor Expansion Plans. Landlord
                  and Tenant agree that such an election by Tenant will result
                  in savings to Landlord, and as such, Landlord agrees that it
                  shall provide Tenant with an additional credit in an amount
                  equal to the difference between (1) $6,100, and (2) the
                  product obtained by multiplying the sum of $6,100 by a
                  fraction, the numerator of which is the number of ceiling
                  tiles that Tenant elects to install in the Fourth Floor
                  Expansion Premises and the denominator of which is the number
                  of ceiling tiles that may be installed in the ceiling grid as
                  configured as of the date hereof (as denominated by Tenant on
                  the Fourth Floor Expansion Plans) (the "Fourth Floor Base
                  Building Credit Allowance"). The Fourth Floor Base Building
                  Credit Allowance shall be paid to Tenant in the same manner as
                  the Landlord's Fourth Floor Expansion Allowance. In addition,
                  in the event that Tenant elects to remove all or any portion
                  of the ceiling grid, Tenant shall pay Landlord an amount equal
                  to the product obtained by multiplying the sum of $12,920 by a
                  fraction, the numerator of which is the square footage of the
                  ceiling grid that is removed, and the denominator of which is
                  the total square footage of the ceiling grid actually
                  installed as of this date (as denominated by Tenant on the
                  Fourth Floor Expansion Plans), which amount shall be paid by
                  Tenant to Landlord on or before the Fourth Floor Expansion
                  Effective Date. Notwithstanding the above, Tenant may, at
                  Tenant's discretion, use up to Fifty-Four Thousand Three
                  Hundred Fifteen and 00/100 Dollars ($54,315.00) of Landlord's
                  Fourth Floor Expansion Allowance for costs related to design
                  and construction of the Fourth Floor Expansion Tenant
                  Improvements, Tenant's signage costs, moving expenses and
                  installation of Tenant's furniture.

         (2)      Landlord shall pay Landlord's Fourth Floor Expansion Allowance

                  conformance with Landlord's reasonable requirements and all
                  applicable codes, ordinances and laws, and shall specify
                  materials and details equal to or better than Landlord's
                  building standard. The Fourth Floor Expansion Plans shall be
                  subject to approval of Landlord (which approval shall not be
                  unreasonably withheld, conditioned or delayed), and the
                  government officials having jurisdiction. Tenant shall submit
                  complete construction plans to Landlord for approval and
                  Landlord shall approve said Fourth Floor Expansion Plans in
                  accordance with Exhibit "E-1".

         (2)      Upon Landlord's approval of the Fourth Floor Expansion Plans
                  and completion of Landlord's Fourth Floor Expansion Work,
                  Tenant shall be authorized to proceed with the improvement of
                  the Premises in accordance with the Fourth Floor Expansion
                  Plans. Exhibit "C-1" provides the intermediate actions
                  required of both Landlord and Tenant to satisfy the schedule
                  hereof. Landlord shall have the right to engage such technical
                  consultants, planners, and engineers as may be reasonably
                  required to assist Landlord in evaluating the Fourth Floor
                  Expansion Tenant Improvements and the Fourth Floor Expansion
                  Plans, all at Tenant's sole cost and expense; provided,
                  however, that in no event shall Tenant's cost therefor exceed
                  1.5% of aggregate amount of the Specified Contract Amounts and
                  the Generator and Supplemental HVAC Costs.

65.      TENANT'S WORK

         All work not within the scope of the normal construction trades
employed in the Building, including, but not limited to, furnishing and
installing of the Telecommunications Equipment, telephones, furniture, and
office equipment shall be furnished and installed by Tenant at Tenant's expense.
Tenant's Contractors shall be acceptable to and approved by Landlord (which
approval shall not be unreasonably withheld, conditioned or delayed), and shall
be subject to the reasonable administrative supervision of Landlord. Contractors
engaged by Tenant shall employ persons and means to insure so far as may be
possible the progress of the work without interruption on account of strikes,
work stoppages or similar causes for delay. Landlord shall give access and entry
to the Fourth Floor Expansion Premises to Tenant and its Contractors and
reasonable opportunity and time and reasonable use of facilities to enable
Tenant to adapt the Expansion Premises for Tenant's use; provided, however, that
if such entry is prior to the Fourth Floor Expansion Effective Date, such entry
shall be subject to all the terms and conditions of the Lease, except the
payment of Rent. In furtherance of the foregoing, Tenant covenants and agrees
that the Fourth Floor Expansion Plans shall include plans outlining specifically
the location of the conduit paths to be installed by Tenant. Any and all such
conduit paths shall be of a size approved by Landlord and shall be installed at
a location in the Building risers specified by Landlord. At Landlord's option,
Landlord may request Tenant to install additional conduit at the time Tenant
installs conduit in the risers for purposes of serving the Premises, and
Landlord shall pay for the cost and expense of such additional conduit and any
incremental labor cost (if any) incurred by Tenant as a result of installation
of such additional conduit. Tenant will not unreasonably withhold, condition or
delay its consent to Landlord's request to so install the additional conduit
described and identified in the immediately preceding sentence.

         that such rates are subject to increases based on market conditions.

2.       RENEWAL OPTION.

         (a)      Tenant, provided that it is not in default and has not sublet
                  the Premises or assigned this Lease, shall have one (1) option
                  to extend the term of this Lease for a period of five (5)
                  years. To exercise such option, Tenant shall be required to
                  give Landlord written notice of Tenant's desire to exercise
                  such option at least eight (8) months prior to the then
                  existing expiration date of the Lease Term.

         (b)      Within fifteen (15) days after Tenant's notice to Landlord
                  setting forth Tenant's desire to extend the Lease Term
                  pursuant to this Paragraph 2, Landlord shall notify Tenant as
                  to whether Landlord approves or denies such extension.
                  Landlord's decision shall be subject to Landlord's reasonable
                  evaluation and consideration of the following:

                  (i)      whether there is an Event of Default under this Lease
                           or any condition which, with the giving of notice and
                           the passage of time, would constitute an Event of
                           Default under this Lease; and

                  (ii)     the status of Tenant's credit at the time of Tenant's
                           notice of its desire to extend the Lease Term.

         (c)      During the Lease Term as extended by this extension option as
                  properly exercised and approved by Landlord, all terms and
                  conditions of this Lease shall remain unchanged and in full
                  force and effect, except that Base Rent during the Lease Term
                  as so extended shall be the then current effective market rate
                  for tenants for similar office space in the Building and as
                  determined in Landlord's reasonable judgment. In determining
                  said then current effective market rate, the following
                  factors, among others, shall be taken into account and given
                  effect: size, location of Premises, lease term, condition of
                  Premises, economic concessions then being granted by Landlord
                  to tenants, and services provided by Landlord.

         (d)      If Tenant is entitled to and properly exercises the foregoing
                  renewal option, Landlord shall prepare an amendment (the
                  "Renewal Amendment") to reflect changes in the Base Rent,
                  Lease Term, termination date and other appropriate terms.
                  Tenant shall execute and return such Renewal Amendment to
                  Landlord within fifteen (15) days after Tenant's receipt
                  thereof from Landlord. If Tenant, in its sole discretion, is
                  not satisfied with the terms of the Renewal Amendment offered
                  by Landlord, Tenant may decline to execute the same and this
                  Lease shall not be extended.

3.       RIGHT OF SECOND REFUSAL.

         Tenant shall have the right of second refusal on the fifth (5th) floor
         of the Building (the "Second Refusal Space"), subject to the prior
         right of first refusal granted to Turner Broadcasting System, Inc. Such
         right of second refusal shall be exercised as follows: In the event
         that, at any time during the Lease Term, Landlord receives and desires
         to accept one or more offers (each, an "Offer") to lease a Second
         Refusal Space and any other tenant of the Building with a prior right
         of first refusal with respect thereto declines to exercise its right of
         first refusal with respect to such Second Refusal Space, then Landlord
         shall advise Tenant in writing (the "Advice") of such facts. The Advice
         shall include a statement that the Advice is being given pursuant to
         the right of second refusal granted in this Lease and a statement that
         Tenant must respond to the Advice within ten (10) days of its receipt
         of same or lose its right to lease the offered space. The Advice shall
         also include the identity of the prospective tenant and a true, correct
         and complete copy of the signed Offer. Tenant may lease such Second
         Refusal Space in its entirety only, under the terms contained in the
         Offer or on such other terms as may be acceptable to Landlord in its
         reasonable discretion, by delivering written notice (the "Notice of
         Exercise") of its election to lease the Second Refusal Space covered by
         such Offer to Landlord within said ten (10) days period, except that
         Tenant shall have no such right of second refusal, and Landlord need
         not provide Tenant with an Advice, if:

                  1.       Tenant is in default under the Lease at the time
                           Landlord would otherwise deliver the Advice; or

                  2.       the Premises, or any portion thereof, is sublet at
                           the time Landlord would otherwise deliver the Advice;
                           or

                  3.       the Lease has been assigned prior to the date
                           Landlord would otherwise deliver the Advice; or

                  4.       Tenant is not occupying the Premises on the date
                           Landlord would otherwise deliver the Advice.

                  The term for the Second Refusal Space shall commence upon the
         commencement date specified in the Advice and thereupon such Second
         Refusal Space shall be considered a part of the Premises, provided that
         all of the terms specified in the Advice shall govern Tenant's leasing
         of the Second Refusal Space and, only to the extent that they do not
         conflict with the Advice, the terms and conditions of this Lease shall
         apply to the Second Refusal Space.

                  The Second Refusal Space (including improvements and
         personalty, if any) shall be accepted by Tenant in its condition and
         as-built configuration existing on the earlier of the date Tenant takes
         possession of the Second Refusal Space or the date the term for such
         Second Refusal Space commences, unless the Advice specifies any work to
         be performed by Landlord in the Second Refusal Space, in which case
         Landlord shall perform such work in the Second Refusal Space.

                  The rights of Tenant hereunder with respect to any Second
         Refusal Space shall terminate on the earlier to occur of (i) the date
         six (6) months prior to the expiration date of the original Lease Term
         (without regard to renewals or extensions thereof); (ii) with respect
         only to any Second Refusal Space described in an Advice (but not
         otherwise), Tenant's failure to exercise its right of second refusal
         within the ten (10) day period provided hereinabove with respect to any
         such Second Refusal Space for which an Advice is so given by Landlord;
         and (iii) with respect only to any Second Refusal Space described in an
         Advice (but not otherwise), the date Landlord would have provided
         Tenant an Advice thereof if Tenant had not been in violation of one or
         more of the conditions set forth hereinabove.

                                   EXHIBIT "G"

<PAGE>   75

              If Tenant exercises its right of second refusal, Landlord shall
         prepare an amendment (the "Amendment") adding the Second Refusal Space
         to the Premises on the terms set forth in the Advice, and reflecting
         the changes in the Base Rent, Approximate Rentable Area of the
         Premises, Tenant's Pro Rata Share, and other appropriate terms. A copy
         of the Amendment shall be (i) sent to Tenant within a reasonable time
         after receipt of the Notice of Exercise executed by Tenant, and (ii)
         executed by Tenant and returned to Landlord within ten (10) days
         thereafter.

4.            TELECOMMUNICATIONS EQUIPMENT.

         Upon, prior to or after completion of the Fourth Floor Expansion
         Premises, Tenant shall have the right, to install the
         Telecommunications Equipment in the Fourth Floor Expansion Premises.
         Tenant agrees that all such equipment shall comply with all applicable
         Lease provisions. Tenant (or its authorized representative) shall (a)
         install the Telecommunications Equipment in compliance with all
         applicable codes, ordinances, and statutes, (b) be responsible to
         obtain all governmental approvals, permits, licenses, and the like
         related to such installation and the operation of the
         Telecommunications Equipment, (c) comply with all insurance
         requirements applicable thereto, and (d) indemnify and hold Landlord
         harmless for any claims, damages, losses, liabilities, or expenses
         (including reasonable attorneys' fees) which Landlord may incur or
         sustain by reason of any failure of Tenant to install the
         Telecommunications Equipment in compliance with all applicable codes,
         ordinances, and statutes and for any damage to the Premises, Building,
         or Property caused by such installation. Landlord shall not be liable
         for the failure of the Telecommunications Equipment (unless caused by
         the negligent action or failure to act by Landlord or its agents) or
         for the improper installation thereof by Tenant. Upon the expiration or
         sooner termination of this Lease, Tenant will remove the
         Telecommunications Equipment and the cabling from the risers, along
         with any ancillary equipment or structures and shall repair any damage
         to the Premises, the Building, or any other improvements to the
         Property caused thereby. Tenant covenants that the Telecommunications
         Equipment will not emit radiation in excess of that which may be
         permitted under applicable law or regulation, as same may be modified
         from time to time, including, without limitation, regulations of the
         Federal Communications Commission, the Environmental Protection Agency,
         and the Occupational Safety and Health Administration, applicable to
         the emission of radiation from active telecommunications equipment or
         similar facilities. Other than with respect to the rights of any
         tenants, occupants or licensees under any currently existing leases or
         licenses for space at the Property to continue to use and enjoy any
         telecommunications or other equipment, Landlord will not knowingly
         perform (or fail to perform) any act or permit any tenant, occupant or
         licensor of the Property, and their respective employees and invitees,
         or any other person or entity to perform (or fail to perform) any act,
         that may interfere with or impede Tenant's use of the
         Telecommunications Equipment. Tenant understands and agrees, however,
         that Landlord may be required to shut down the power or other Building
         services from time to time and, in such event, Landlord shall cooperate
         with Tenant to the fullest extent possible to schedule such matters at
         a time that may be mutually convenient in order to permit to the
         fullest extent possible Tenant to continue to use the
         Telecommunications Equipment in an unimpeded and uninterrupted manner.
         Except in the case of emergency, Landlord shall provide Tenant with
         written notice at least three (3) Business days prior to the date that
         Landlord intends to shut down the power or other Building services. In
         the event that Landlord so shuts down the power or other Building
         services, in no event and under no circumstances shall Tenant's use of
         the Generator, the Rooftop Equipment or the Supplement HVAC Systems be
         impeded or interrupted unless such power or other Building services are
         shut down as a result of an emergency. Landlord shall act reasonably
         and in good faith for purposes of determining whether a state of
         emergency exists sufficient to require the power or other Building
         services to be shut down from time to time.

5.       SUPPLEMENTAL HVAC.

         Subject to (i) compliance with all rules, regulations, statutes and
         codes of any governmental authority having jurisdiction thereover, (ii)
         Landlord's prior written consent, which consent shall not be
         unreasonably withheld, conditioned or delayed, and (iii) Tenant's
         removal and restoration obligation set forth below, Tenant shall have
         the right to install supplemental heating, ventilation and
         air-conditioning systems (the "Supplemental HVAC Systems"), to provide
         HVAC capacity to the Premises sufficient for Tenant's Permitted Use.
         The foregoing shall include granting to Tenant a right of access to,
         and the non-exclusive use of, areas outside the Premises (including
         areas within which the Building HVAC equipment and accessories are
         located), for installation, maintenance, repair and (if necessary)
         replacement of certain components of such Supplemental HVAC Systems;
         provided such access shall be coordinated with Landlord and conducted
         at such times and in such manner as is reasonably approved by Landlord
         in order to ensure that any such work is performed properly, in
         compliance with all applicable legal requirements and with a minimum of
         disruption to, interference with and/or interruption of the quiet use
         and enjoyment by all tenants of the Building of their respective
         premises and the common areas. Although the precise location of the
         principal components of the Supplemental HVAC Systems cannot be finally
         determined until such time as Landlord has reviewed Tenant's Plans with
         respect thereto, Landlord presently anticipates that such principal
         components will be located in the parking garage directly across from
         the northeast side of the second floor of the Building. The precise
         location of the Supplemental HVAC Systems (and its principal
         components) shall be identified by Landlord upon approval by Landlord
         of Tenant's Plans. Any parking spaces eliminated as a result of the
         installation of the Supplement HVAC Systems shall be paid for by Tenant
         at the prevailing rate from time to time, and any such parking spaces
         so utilized by Tenant for installing and operating the Supplement HVAC
         Systems shall reduce the number of parking spaces otherwise available
         to Tenant pursuant to the terms and provisions of Paragraph 1 of these
         Special Stipulations. In connection with Landlord's evaluation and
         identification of the location of the Supplemental HVAC Systems (and
         its principal components), Tenant acknowledges and agrees that Landlord
         must approve the size, weight, drainage, and other specifications of
         the Supplemental HVAC Systems, its integration with any Building
         systems, and any impact it may have thereon, and that Tenant shall
         install at Landlord's direction such screening as Landlord may require
         for purposes of making the area surrounding the Supplemental HVAC
         Systems esthetically pleasing and reducing any noise and vibration
         emanating from the Supplemental HVAC Systems (which screening shall be
         constructed and installed by Tenant at its sole cost and expense).
         Although the precise location of the Supplemental HVAC Systems (and its
         principal components) cannot be identified as of this date, Landlord
         hereby represents and warrants that it will designate an area of the
         Property outside the Premises for purposes of locating, constructing
         and installing the Supplemental HVAC Systems (and its principal
         components). In connection with the foregoing, Tenant shall be
         permitted to vent out the portion of the Fourth Floor Expansion
         Premises (the precise location of which shall be approved by Landlord)
         which faces the rear of the Building, at Tenant's sole cost and
         expense. Tenant (a) shall install the Supplemental HVAC Systems in
         compliance with all applicable codes, ordinances, and statutes, (b)
         shall be responsible to obtain all governmental approvals, permits,
         licenses, and the like related to such installation, (c) shall comply
         with all legal and insurance requirements applicable thereto, and (d)
         shall indemnify and hold Landlord harmless for any claims, damages,
         losses, liabilities, or expenses (including reasonable attorneys' fees)
         which Landlord may incur or sustain by reason of any failure of Tenant
         to install the Supplemental HVAC Systems in compliance with all
         applicable codes, ordinances, and statutes and for any damage to the
         Premises, Building, or Property caused by such installation. Landlord
         shall not be liable for the failure of the Supplemental HVAC Systems
         (unless caused by the negligent action or failure to act by Landlord or
         its agents) or for the improper installation thereof by Tenant. Upon
         the expiration or sooner termination of this Lease, Tenant shall remove
         the Supplemental HVAC Systems installed pursuant hereto (along with any
         and all ancillary equipment or structures) from the Premises and repair
         any damage to the Premises or Building caused by such removal.

6.       GENERATOR.

         Subject to (i) compliance with all rules, regulations, statutes and
         codes of any governmental authority having jurisdiction thereover, (ii)
         Landlord's prior written consent as to the location and design and
         installation plans and specifications therefor, which consent shall not
         be unreasonably withheld, delayed or conditioned, and (iii) Tenant's
         removal and restoration obligation set forth below, Tenant shall have
         the right to purchase and install one generator (including any
         necessary appurtenant equipment that is a part thereof, the
         "Generator") and one fuel storage tank for the Generator (the
         "Generator Fuel Tank") in the lower level of the parking garage of the
         Building at a spot to be more specifically identified by Landlord (the
         "Generator Area"). The precise location of the Generator shall be
         determined based on the size and specifications of the Generator
         submitted by Tenant to and approved by Landlord. Any parking spaces
         eliminated after the date hereof as a result of the installation of the
         Generator and Generator Fuel Tank shall be paid for by Tenant at the
         prevailing rate from time to time, and any such parking spaces so
         utilized by Tenant for installing and operating the Generator and
         Generator Fuel Tank shall reduce the number of parking spaces otherwise
         available to Tenant pursuant to the terms and provisions of Paragraph 1
         of these Special Stipulations. Additionally, Landlord shall furnish a
         pathway for Tenant to run lines from the Premises to the Generator at a
         location chosen by Landlord as more fully set forth in Paragraph 7
         hereof. Tenant's installation, use and operation of the Generator and
         the Generator Fuel Tank shall be exercised: (1) in such manner as will
         not create any hazardous condition or interfere with or impair the
         operation of the heating, ventilation, air conditioning, plumbing,
         electrical, fire protection, life safety, public utilities or other
         systems or facilities in the Building; (2) in compliance with all
         applicable laws, codes and regulations and the requirements of any
         board of fire insurance underwriters or other similar bodies now or
         hereafter constituted relating to or affecting thereto; (3) in such a
         manner as will not directly or indirectly interfere with, delay,
         restrict or impose any expense, work or obligation upon Landlord in the
         use or operation of such Building; and (4) at Tenant's cost, including
         the cost of repairing all damage to the Building and any personal
         injury and/or property damage attributable to the installation,
         inspection, adjustment, maintenance, removal or replacement of any
         equipment, apparatus or facilities pursuant to this Paragraph 6. In
         connection with Tenant's use of the Generator and the Generator Fuel
         Tank, and subject to the above-stated responsibilities of Tenant,
         Tenant shall have the right to operate the Generator at such intervals
         and for such periods of time as may be recommended by or required by
         the manufacturer of such generator for testing or maintenance purposes,
         or at such other intervals as Tenant deems necessary in its reasonable
         judgment for purposes of operating its business; provided (i) to the
         fullest extent possible, Tenant will provide notice to Landlord of the
         scheduled times for such regular testing and operation for maintenance
         purposes, (ii) Tenant will use all reasonable and diligent efforts to
         perform any testing or periodic operation for maintenance purposes
         outside of Normal Business Hours (it being acknowledged by Landlord
         that certain testing and operation for maintenance and other business
         purposes will necessarily take place during peak operational periods,
         which may include during Normal Business Hours), and (iii) such testing
         will be performed in a manner reasonably calculated to minimize any
         inconvenience to other tenants and occupants of the Building, and their
         respective employees and invitees.

         Tenant will obtain prior to the installation of the Generator and
         Generator Fuel Tank, any and all necessary licenses, approvals and
         permits necessary for the installation, maintenance and use of the
         Generator, Generator Fuel Tank and any equipment installed in
         connection therewith. Tenant shall indemnify and hold Landlord harmless
         from and against any and all loss, cost (including reasonable
         attorney's fees incurred in defending Landlord), damage or liability
         arising out of any violations of any laws, statutes, ordinances, rules
         or regulations, or arising out of the use, operation and maintenance of
         the Generator and the Generator Fuel Tank, including, without

                                   EXHIBIT "G"
                                  Page 5 of 12
<PAGE>   78

         limitation any damage Landlord may sustain as a result of the
         malfunction, leaking or any other condition of the Generator, Generator
         Fuel Tank or other related equipment described in this paragraph. If
         the rate of any insurance carried by Landlord is increased as a result
         of Tenant's installation of the Generator and related Generator Fuel
         Tank, then Tenant will pay to Landlord within thirty (30) days after
         Landlord delivers to Tenant a certified statement from Landlord's
         insurance carrier stating that the rate increase was caused thereby, a
         sum equal to the difference between the original premium and the
         increased premium resulting therefrom. Upon the expiration or sooner
         termination of this Lease, Tenant shall remove the Generator and
         Generator Fuel Tank along with any ancillary equipment or structures
         and shall repair any damage to the Premises, the Building, or any other
         improvements to the Property caused thereby.

7.       CONNECTING RIGHTS.

         Landlord agrees that the right of Tenant to install the facilities and
         systems described in Paragraphs 4, 5, 6, 10 and 13 hereof includes (i)
         the right to connect such systems to the Premises by running supply
         lines, connections, cabling and other appropriate means of connection
         from the areas of the Building within which certain equipment forming a
         part of such systems are installed to all areas of the Premises,
         including the use of vertical risers, core areas and other means of
         connection as are shown on the Plans or as may otherwise be designated
         by Landlord in good faith, and (ii) a right of access to such areas in
         order to perform necessary maintenance, repair, replacement (if
         necessary) and testing, provided such access shall be coordinated with
         Landlord and conducted at such times and in such manner as is
         reasonably approved by Landlord in order to ensure that any such work
         is performed properly, in compliance with all applicable legal
         requirements and with a minimum of disruption to, interference with
         and/or interruption of the quiet use and enjoyment by all tenants of
         the Building of their respective premises and the common areas.
         Landlord warrants and represents that the right of quiet enjoyment
         granted by Landlord to other tenants of the Building will not impede or
         unreasonably interfere with the rights granted to Tenant in
         subparagraphs (i) and (ii) of this Paragraph (it being understood,
         however, that such Tenant rights shall be subject to the reasonable
         rules and regulations of Landlord designed to minimize any disruption
         to or interference with the quiet use and enjoyment by other tenants of
         the Building). In performing the connections and other activities
         described in this Paragraph, Tenant (a) shall perform same in
         compliance with all applicable codes, ordinances, and statutes, (b)
         shall be responsible to obtain all governmental approvals, permits,
         licenses, and the like related thereto, (c) shall comply with all legal
         and insurance requirements applicable thereto, (d) shall repair and/or
         restore any areas of Building or Land affected thereby, and (e) shall
         indemnify and hold Landlord harmless for any claims, damages, losses,
         liabilities, or expenses (including reasonable attorneys' fees) which
         Landlord may incur or sustain by reason of any failure of Tenant to
         perform same in compliance with all applicable codes, ordinances, and
         statutes and for any damage to the Premises, Building, or Property
         caused thereby. Unless Landlord notifies Tenant no later than ninety
         (90) days prior to the last day of the Lease Term that it is requiring
         Tenant to surrender the connections and lines described in this
         Paragraph 7 as redesigned by Tenant in accordance herewith upon the
         expiration or sooner termination of this Lease (in which case the same
         shall be surrendered by Tenant at such time), then Tenant will, on or
         before the date of expiration or sooner termination of this Lease (and
         at Tenant's sole expense), remove such connections and repair any
         damage to the Premises, the Building, or any other improvements to the
         Property caused thereby, provided the foregoing removal obligation will
         not be construed to require the removal of any cables or
         telecommunications lines which thereafter continues to serve as a
         connection to telecommunications service being provided to tenants of
         the Building. Landlord agrees to cooperate with Tenant and its general
         contractor to facilitate such access, provided (i) such access will be
         scheduled at night or during other non-business hours, or at such other
         times as may be consented to by the affected tenants, consistent with
         the rights of such tenants pursuant to

                                   EXHIBIT "G"
                                  Page 6 of 12
<PAGE>   79

         their leases, including the right of quiet enjoyment, (ii) such work
         shall be performed in accordance with all of the provisions of this
         Paragraph 7 with regard to the performance of such work by Tenant and
         its contractors, and (iii) such work will be performed as expeditiously
         as possible, in a manner which will cause a minimum of disturbance and
         disruption to the affected tenants, and in all events in a manner which
         will not violate the rights of such affected tenants, or their quiet
         enjoyment, under their respective leases. Without limitation, unless
         approved by the affected tenant(s), the foregoing will include
         protection of any furniture, fixtures and/or equipment of such affected
         tenants, removal of construction equipment, tools and other items
         necessary to perform such work from the affected areas except when such
         work is actively being conducted, and daily clean-up of construction
         debris, dust and materials in a manner acceptable to the affected
         tenants.

8.       FLOOR LOADING.

         Tenant agrees that it shall not place a load upon any floor which
         exceeds the load per square foot which such floor was designed to carry
         and which is allowed by law; provided, however, that Landlord shall
         permit reinforcing the load capacity of the Fourth Floor Expansion
         Premises and the Third Floor Expansion Premises (and, possibly, the
         Fifth Floor in the event Tenant occupies the Fifth Floor pursuant to
         this Lease, or otherwise) (collectively, the "Permitted Reinforcement
         Floors"), pursuant to plans and specifications approved by Landlord
         (which approval shall not be unreasonably withheld, conditioned or
         delayed), so long as (a) Tenant shall remove any and all improvements
         constructed or installed by Tenant for purposes of so reinforcing the
         Permitted Reinforcement Floors upon the expiration or earlier
         termination of the Lease, and (b) any and all improvements so
         constructed or installed by Tenant for purposes of so reinforcing the
         Permitted Reinforcement Floors are located within the Premises leased
         from time to time by Tenant (and the Fifth Floor of the Building in the
         event Tenant occupies such Fifth Floor pursuant to this Lease, or such
         other areas in, on or about the interior of the Building core as
         permitted by Landlord in writing, which permission shall not be
         unreasonably withheld, conditioned or delayed.), and shall not be
         visible in any way from the exterior of the Premises.

9.       FIRE PROTECTION.

         Landlord consents and agrees to the installation by Tenant of a fire
         protection system within the Fourth Floor Expansion Premises, which
         shall be a FM200 fire suppression, dry sprinkler system (or such other
         system approved by Landlord, which approval shall not be unreasonably
         withheld, conditioned or delayed). Landlord will enable Tenant to
         connect up to ten (10) zones to Landlord's fire alarm system. All costs
         including programming the system shall be at Tenant's sole cost and
         expense. All costs associated with the modification or removal of any
         existing Landlord systems shall be at Tenant's sole cost and expense.

10.      ELECTRICAL.

         In order to accommodate and provide adequate electrical service for
         Tenant's Permitted Use within the Fourth Floor Expansion Premises,
         Tenant will be permitted to supplement the electrical service serving
         the Fourth Floor Expansion Premises in order to utilize at all times
         during the Term an additional 2,000 amps of 3 Phase, 480 volt
         electrical service available to the Building (in addition to that which
         is currently available as part of the Building standard), provided that
         such service will be installed from the Building electrical room to the
         Fourth Floor Expansion Premises at Tenant's sole expense, all in
         accordance with plans approved by Landlord, not to be unreasonably
         withheld, conditioned or delayed. At such time as Landlord's
         electrician has certified that such additional 2000 amps of electrical
         service is available in the Building electrical room for Tenant's
         installation into the Fourth Floor Expansion Premises, Tenant agrees

                                   EXHIBIT "G"
                                  Page 7 of 12
<PAGE>   80

         to pay Landlord a single, lump sum payment of $50,000.00 for such
         electrical service, which amount shall be deemed and construed to be a
         Tenant Cost under the terms of the Fourth Floor Expansion Premises
         Lease Improvement Agreement (and therefore eligible for payment from
         Landlord's Fourth Floor Expansion Allowance in accordance with the
         terms of the Fourth Floor Expansion Premises Lease Improvement
         Agreement). Landlord hereby warrants and represents that the aforesaid
         additional 2000 amps are presently available to the Building and will
         remain available to the Building for Tenant's sole and exclusive use
         during the Term. Without limitation, Tenant agrees that any
         modifications to the electrical systems contemplated herein must be
         performed and conducted at such times and in such manner as will avoid
         to the fullest extent possible and practical any disruption or
         interruption in electrical service to the Building which are either
         occupied or otherwise in use. Landlord must approve any disruption or
         interruption in electrical service to any other areas of the Building,
         which approval shall not be unreasonably withheld, conditioned or
         delayed so long as such interruption is scheduled during non-business
         hours. In addition, upon notice by Tenant submitted no earlier than the
         first anniversary of the Fourth Floor Expansion Effective Date (and no
         later than the third anniversary of the Fourth Floor Expansion
         Effective Date, after which time Tenant's rights contemplated in this
         sentence shall expire), Tenant shall have the right to request an
         additional 1,000 amps of 3 Phase, 480 volt electrical service (in
         addition to that which is described hereinabove) for purposes of
         servicing the Fourth Floor Expansion Premises, but not otherwise. Upon
         receipt of Tenant's request, Landlord shall provide Tenant with an
         estimate of the cost of providing such service to the Building
         electrical room. Upon receipt of Tenant's payment of the anticipated
         cost of providing such electrical service (together with a fee in the
         amount of ten percent (10%) of such cost to be paid to Landlord on
         account of the cost to order, construct, and install such additional
         service to the Building electrical room), Landlord shall enter into
         such contracts as may be necessary or appropriate, if any, for purposes
         of arranging for such additional electrical service to be provided to
         the Building electrical room, and shall thereafter diligently pursue
         the construction and installation of such service through completion.
         Landlord hereby warrants and represents that the aforesaid additional
         1000 amps are presently available to the Building and will remain
         available to the Building for Tenant's sole and exclusive use during
         the Term if Tenant exercises its rights thereto as provided herein on
         or before the third anniversary of the Fourth Floor Expansion Date (at
         which time Tenant's right to such additional amps shall terminate if
         not then exercised by Tenant pursuant to the terms hereof). In the
         event that Tenant requests any additional electrical service beyond
         that which is described in the immediately preceding provisions of this
         Special Stipulation, Landlord shall cooperate in good faith with Tenant
         to provide such additional service so long as the allocation of such
         additional service shall not, in Landlord's sole determination,
         adversely affect Landlord's ability to provide existing or future
         tenants of the Building with the level of electrical service Landlord
         may anticipate to be utilized by such tenants. In the event that
         Landlord is unable to accommodate Tenant's request for additional
         electrical service in excess of the additional 3000 amps described
         hereinabove, Landlord shall cooperate with Tenant to permit Tenant to
         purchase additional electrical service directly from Georgia Power or
         any other provider of electrical service to the Building. Any and all
         costs and expenses associated with such installation or use of the
         additional power shall be paid for by Tenant. In the event that
         Landlord is in a position to accommodate Tenant's request for
         additional electrical service beyond that which is expressly provided
         for in this Special Stipulation, Landlord shall provide Tenant with an
         estimate of the cost of providing such service. Upon receipt of
         Tenant's payment of the anticipated cost of providing such additional
         electrical service (together with a fee in the amount of ten percent
         (10%) of such cost to be paid to Landlord on account of the cost to
         order, construct and install such additional service to the Building
         electrical room), Landlord shall enter into such contracts as may be
         necessary or appropriate for purposes of arranging for such additional
         electrical service to be provided to the Building electrical room for
         installation to the Premises by Tenant, and shall thereafter diligently
         pursue the construction and installation of such service to the
         Building electrical room through completion.

11.      SOUND CONTROL.

         Tenant is responsible for taking the necessary measures to reduce any
         sound transmissions caused by Tenant's Telecommunications Equipment
         between the Premises and the adjacent premises. In addition, the
         Generator, including radiator, shall be installed in a walk-around
         type, sound attenuating enclosure which shall limit the sound to no
         more than 85 dBA as measured at three (3) feet from any side, top or
         bottom, under all operating conditions.

12.      ADDITIONAL SECURITY SYSTEM.

         Tenant hereby agrees to the exercise by Landlord and its agents and
         employees, within their sole discretion, of such security measures as
         Landlord deems necessary or appropriate for the Building.
         Notwithstanding the foregoing, Tenant may install a security system
         within the Premises, provided such system and its installation (i)
         shall be subject to Landlord's prior written approval, which shall not
         be unreasonably withheld (provided it shall not be unreasonable for
         Landlord to deny consent to any system which is not compatible with the
         building's overall security and fire safety and life safety systems),
         (ii) shall be in accordance with all applicable legal requirements
         (iii) shall be performed at Tenant's sole expense, and shall be
         otherwise installed in accordance with the provisions governing
         alterations under Section 8 of the Lease.

13.      MFS FIBER.

         Landlord and Tenant agree to cooperate for purposes of facilitating the
         installation by MFS/Worldcom of fiber optic service (the "MFS Fiber")
         to the Building. Landlord and Tenant acknowledge that there are no
         assurances that MFS/Worldcom will agree to install the MFS Fiber to the
         Building, and neither such party shall have any obligation to pay any
         cost or expense in connection with such installation to the Building.
         In the event that MFS/Worldcom so elects to install the MFS Fiber to
         the Building, Tenant shall pay the cost and expense of installing such
         cable, conduit, and other improvements as may be required for purposes
         of connecting the MFS Fiber from the point at which the MFS Fiber is
         installed in the Building to the Premises. Landlord agrees that in the
         event that the MFS Fiber is installed in the Building, Landlord shall
         (a) use reasonable efforts to cooperate with MFS/Worldcom to ensure the
         continuous operation and maintenance of the MFS Fiber in the Building
         and the Premises during the Lease Term, and (b) take no action which
         would cause the termination or interruption of the MFS Fiber service to
         the Building or the Premises without Tenant's prior consent, which
         consent shall not be unreasonably withheld, conditioned or delayed.

14.      ROOF EQUIPMENT.

         It is understood by Landlord that Tenant may desire to install two
         satellite dishes and a microwave relay station antenna (the "Roof
         Equipment") on the roof of the Building for the purpose of transmitting
         and receiving aerial transmissions. At least thirty (30) days prior to
         the time that Tenant contemplates installation of the Roof Equipment,
         Tenant shall deliver to Landlord detailed specifications for the Roof
         Equipment, and Landlord and Tenant shall use their reasonable efforts
         to determine and agree to a location on the roof of the Building where,
         and a method by which, the Roof Equipment can be installed by Tenant
         (but at no cost or expense to Landlord) without, in the reasonable
         judgment of Landlord and the design architect of the Building (which
         judgment shall not be unreasonably withheld or delayed), interfering
         with or impeding the operations of Landlord or the operations of any
         present tenant of the Building at the time the Roof Equipment is
         installed, or requiring any design or other changes to the Building.

                                   EXHIBIT "G"
                                  Page 9 of 12
<PAGE>   82

         At such time as the location and installation method are thus
         determined and agreed, Tenant, at its sole cost and expense, may
         install such Roof Equipment at the location and in the manner agreed by
         Landlord and Tenant at such time as Landlord shall reasonably designate
         (it being understood and agreed that Landlord hereby represents and
         warrants that Landlord shall reserve at all times during the Term of
         the Lease space sufficient on the Roof to install the Roof Equipment of
         the kinds and types customarily installed by communication companies
         with communications requirements comparable to Tenant's). If the agreed
         location for the Roof Equipment is in such a position that the Roof
         Equipment will be visible from the ground, Landlord may require that
         Tenant, at Tenant's expense, provide, install and maintain an
         appropriate screen around the Roof Equipment. Tenant shall cause the
         installation of the Roof Equipment and any screen to be conducted in a
         good, workmanlike and lien-free manner that will not interfere with or
         impede the operation of the Building and the conduct of business by
         other tenants of the Building. Tenant shall perform such installation,
         and shall at all times maintain and operate the Roof Equipment in such
         a manner as to always be in compliance with all applicable governmental
         codes, statutes, ordinances, rules and regulations and all requirements
         of Landlord's and Tenant's insurance policies, and shall obtain such
         licenses or permits as may be required by applicable law. Landlord
         makes no warranties whatsoever as to the permissibility of, or the
         ability to obtain licenses or permits with respect to, the Roof
         Equipment. Prior to installation of the Roof Equipment and throughout
         the Lease Term upon Landlord's request, Tenant shall provide Landlord
         with documentation (i) evidencing that Tenant has entered into an
         appropriate contract for the regular maintenance and monitoring of the
         Roof Equipment, and (ii) confirming that Tenant's liability insurance
         as required under Paragraph 12 of this Lease covers all of Tenant's
         activities in installing, maintaining and operating the Roof Equipment.
         Tenant agrees that it shall pay Landlord as additional Rent the sum of
         $1,200.00 per year for each satellite dish comprising a portion of the
         Roof Equipment installed pursuant to the provisions of this Special
         Stipulation, and $1,000.00 per year for the microwave relay station
         antenna comprising the balance of such Roof Equipment. Landlord shall
         incur no cost or expense related to or arising out of the Roof
         Equipment or the purchase, installation, maintenance, repair or
         operation of the Roof Equipment, Tenant agreeing to pay all of same.
         Tenant hereby indemnifies and agrees to hold Landlord harmless from and
         against any and all loss, cost, damage and liability incurred by
         Landlord arising out of or related to the Roof Equipment or Tenant's
         purchase, installation, maintenance, repair or operation of the Roof
         Equipment. If at any time during the term of this Lease after the
         initial installation of the Roof Equipment, Landlord determines that
         the location or operation of the Roof Equipment impedes the operation
         of the Building or impedes the operations of any tenant (other than any
         Tenant in the Building prior to the date hereof which Tenant hereby
         covenants not to disturb through the use of the Roof Equipment) or
         proposed tenant of the Building, then Landlord, at Landlord's expense
         (and without disruption or interruption of the operation of the Rooftop
         Equipment during any period of relocation without Tenant's consent,
         which consent shall be provided at reasonable times upon reasonable
         notice), may relocate the Roof Equipment to another location on the
         roof which location shall be subject to Tenant's reasonable approval.
         In addition, Tenant hereby recognizes, understands and agrees that
         Landlord is entitled to install for its own account, or permit the
         installation by other tenants or persons, other antenna and
         telecommunication facilities on the roof of the Building without
         Tenant's approval or consent after the date hereof so long as the
         installation and/or operation of such antenna or other
         telecommunications equipment will not unreasonably interfere with the
         operation of Tenant's Roof Equipment. At the end of the Lease Term,
         Tenant, at Tenant's sole cost and expense, shall remove the Roof
         Equipment from the Building, and shall restore the roof of the Building
         to its condition as of the Commencement Date.

15.      INTERPRETATION.

         In the event of any direct or indirect conflict between the terms of
         this Exhibit "G" and the terms of the body of this Lease, and any
         Exhibits hereto, this Exhibit "G" shall govern and control in all
         respects.

16.      ACCESS.

         Subject in all respects to the provisions of this Lease governing
         casualty, condemnation, governmental regulation or intervention and
         emergencies, Tenant and Tenant's employees, agents, sub-contractors,
         invitees, assignee's and licensee's shall have continuous and
         uninterrupted access (24 hours per day on every day of each year during
         the Lease Term) to the Premises, Telecommunications Equipment,
         Supplemental HVAC Systems, Generator Area, Generator, Generator Fuel
         Tank, the connectors described in Paragraph 5(d) of this Exhibit "G",
         the Roof Equipment, and the MFS Fiber (collectively, the "Tenant
         Area"), for purposes concerning or pertaining to Tenant's Permitted
         Use, including without limitation, the delivery, installation,
         maintenance and repair of equipment or other personal property therein
         or thereto.

17.      QUIET ENJOYMENT.

         Landlord represents and warrants that Tenant shall peaceably and
         quietly have, hold and enjoy the right to use the Tenant Area without
         interference, hindrance or molestation from Landlord or any party
         claiming by, through or under Landlord upon (and subject to) the terms
         and conditions of this Lease.

18.      ADDITIONAL BUILDING SERVICES.

         Landlord and Tenant have agreed that Tenant may install the
         Supplemental HVAC Systems that will require additional chilled water as
         part of the installation and operation thereof. As such, Tenant shall
         cause a special meter or submeter (as directed by Landlord) to be
         installed in order to measure the actual amount of chilled water
         consumed by Tenant. In addition, Landlord and Tenant anticipate that
         the Telecommunications Equipment and the Supplemental HVAC Systems will
         result in the use of electrical current in excess of the building
         standard allocated in accordance with Exhibit "H"attached hereto. Upon
         receipt of Tenant's Plans for the Fourth Floor Expansion Premises,
         Landlord shall cooperate with Tenant for purposes of identifying such
         meters and submeters as may be required to be installed for purposes of
         measuring the amount of electrical current so utilized by Tenant in
         excess of the foregoing building standard allocation, and Tenant shall
         construct and install such meters or submeters as part of the Fourth
         Floor Expansion Tenant Improvements. The cost and expense of such
         meters or submeters, as the case may be, for purposes of measuring
         chilled water and/or electricity shall be paid for and installed by
         Tenant at its sole cost and expense. Landlord shall cause such meters
         or submeters to be read monthly, in arrears, and shall render an
         invoice to Tenant for the services measured thereby to be paid at the
         time and in the manner Base Rent and other charges are required to be
         paid hereunder.

         Finally, Landlord and Tenant acknowledge that this Lease permits Tenant
         to install Telecommunications Equipment on the Third Floor Expansion
         Premises (and, possibly, the Fifth Floor in the event that Tenant
         occupies the Fifth Floor pursuant to the terms of this Lease, or
         otherwise) (the "Additional Telecommunications Space"). In the event
         that Tenant elects to utilize Additional Telecommunications Space for
         the construction, installation and operation of Telecommunications
         Equipment, Landlord must review and approve (which approval shall not
         be unreasonably withheld, conditioned or delayed) all equipment, tenant
         improvement, and other plans proposed by Tenant for purposes of
         constructing, installing and operating any Telecommunications Equipment
         within the Additional Telecommunications Space as a condition to
         Landlord's permission to so construct, install and operate any
         Telecommunications Equipment

                                   EXHIBIT "G"
                                 Page 11 of 12

         within the Additional Telecommunications Space. Tenant hereby ratifies
         and confirms the provisions of the Lease requiring Tenant to pay for
         any increased usage in electricity (including any additional electrical
         amperage contemplated by the provisions of Paragraph 10 of these
         Special Stipulations), water, or other utilities serving the Premises
         in excess of those services generally consumed by tenants of general
         office space, and shall install such meters or submeters (as directed
         by Landlord) for purposes of measuring the consumption of such
         additional utilities or other services as a result of the installation
         of the Telecommunications Equipment in the Additional
         Telecommunications Space, or otherwise.
