                                  OFFICE LEASE

         THIS LEASE AGREEMENT (the "Lease"), dated as of November 16, 1999, made
by and between the undersigned Landlord and the undersigned Tenant;

                          W I T N E S S E T H  T H A T:

         Landlord, for and in consideration of the rents, covenants,
agreements, and stipulations herein contained, to be paid, kept, and
performed by Tenant, has leased and rented, and by these presents hereby
leases and rents unto Tenant, and Tenant hereby leases upon the terms and
conditions herein contained, the Premises described in Section 1.1(b) below,
with no easement for light or air included in the Premises. This Lease shall
create the relationship of landlord and tenant between Landlord and Tenant;
no estate shall pass out of Landlord, and Tenant has only a usufruct which is
not subject to levy and sale. So long as Tenant shall observe and perform the
covenants and agreements binding on it hereunder and subject to the terms and
provisions hereof, Tenant shall at all times during the Lease Term peacefully
and quietly have and enjoy possession of the Premises.

         This Lease shall be applied and construed in a commercially reasonable
manner. Whenever herein the consent, approval or concurrence of either Landlord
or Tenant shall be required for action or forbearance by the other party, it is
agreed that such consent, approval or concurrence shall not be unreasonably
withheld, delayed or conditioned, except as to matters specified as being in the
"sole discretion" of the party from which the consent, approval or concurrence
is required. Such specific discretionary consent, approval or concurrence may be
withheld, delayed or conditioned without regard to any standard of
reasonableness.

                                       I.

                         PREMISES AND OTHER DEFINITIONS

         Unless the context otherwise specifies or requires, the following terms
shall have the meanings herein specified:

                                       1
<PAGE>

         1.1      PREMISES. Terms used in defining Premises are

                  (a) The term "Building" shall mean Pershing Point Plaza,
         located at 1375 Peachtree Road, N.E., Atlanta, Georgia 30309 which
         consists of an office building with a terrace level and seven (7)
         floors of office space.

                  (b) The term "Premises" shall mean that portion of the
         Building located on the floors of the Building specified in the Lease
         Summary, which portion is shown on the floor plan(s) attached hereto as
         EXHIBIT "A". Landlord and Tenant acknowledge that the location of the
         space to be leased to Tenant as Phase 5 will be determined by whether
         or not an existing tenant of the Building, Benefit Services
         Corporation, a Georgia corporation or its successors or assignees
         ("BSC"), renews its lease for a term extending beyond the existing
         expiration date of such term, which is August 31, 2001. If Landlord and
         BSC renew the BSC lease, then Phase 5 shall be the space shown as
         Option A in the Lease Summary. If Landlord and BSC do not renew the
         lease of its space, then Phase 5 shall be the space shown as Option B
         in the Lease Summary. Landlord shall advise Tenant of which option will
         apply to Tenant's lease of Phase 5 under this Lease after the deadline
         by which BSC must exercise its option to renew its lease under the
         terms of its existing lease of space in the Building. Under either
         Option A or Option B, and notwithstanding anything this Lease to the
         apparent contrary, Tenant has agreed to lease from Landlord, and
         Landlord has agreed to lease to Tenant, in accordance with the terms of
         this Lease, not less than 264,174 square feet of Rentable Area on the
         schedule set forth in the Lease Summary under the heading "Occupancy
         and Delivery Date Schedule."

                  (c) Upon any expansion or contraction of the Premises pursuant
         to the terms of this Lease or other agreement of the parties, the term
         "Premises" shall be deemed to apply to such space as adjusted by such
         expansion or contraction.

         1.2  AREA OF THE PREMISES AND BUILDING - Terms used in defining the
area of the Premises and the Building are:

                  (a) The "Rentable Area" of the Premises and the Building for
         all purposes of this Lease shall be the agreed quantity of square
         footage so designated in the Lease Summary as "Area of the Premises,"
         subject to Section 1.2(c) below The "Rentable Area" of any space on any
         multi-tenant floor of the Building shall be determined by multiplying
         the " Usable Area" (as defined below) of such space by a factor of 1.15
         and the "Rentable Area" of any space on any floor of the Building

                                       2
<PAGE>

         leased entirely to a single tenant shall be determined by multiplying
         the Usable Area of such space by a factor of 1.10.

                  (b) The "Usable Area" of the Premises and of the Building for
         all purposes of this Lease shall be the "usable area" thereof
         determined pursuant to the Standard Method for Measuring Floor Area in
         Office Buildings (ANSI/BOMA Z65.1-1996 (the "BOMA Standards"). For
         purposes of the foregoing, "Usable Area" shall not include sill areas,
         porches, areas under roof line overhangs, areas devoted to Building
         standard mechanical rooms, Building standard bathrooms (other than
         private bathrooms), Building standard electrical room, Building
         standard telephone equipment rooms, Building standard stairwells, fire
         towers, Building standard elevator shafts, Building standard flues,
         vents, stacks, pipes and pipe shafts, Building standard vertical shafts
         and ducts and other similar areas that are part of the Base Building
         Condition or their enclosing walls.

                  (c) Landlord and Tenant acknowledge that the Rentable Areas of
         the Premises and the Building as set forth in the Lease Summary are
         estimates only, and that after delivery of each Phase of the Premises
         (as defined in Section 2.1 below), Landlord will cause the architect of
         record for the Building to measure the Usable Area of such Phase of the
         Premises in accordance with the BOMA Standards. Tenant shall have ten
         (10) days after receipt of such certification to independently verify
         the calculations of Landlord's architect and to notify Landlord of any
         objection thereto; if Tenant fails to notify Landlord of any such
         objections within such ten (10) day period, then the certification of
         Landlord's architect shall be deemed confirmed by Tenant and binding on
         both parties hereto. If Landlord and Tenant are unable to agree upon
         the Usable Area of any Phase of the Premises or any other portion of
         the Building, either party may submit the subject matter of their
         dispute to binding arbitration by the American Arbitration Association
         office in Atlanta, Georgia in accordance with the rules thereof. After
         Landlord's architect certifies its calculation of the Usable Area of a
         Phase of the Premises and Tenant has confirmed, or is deemed to have
         confirmed, such calculation or such calculation is determined by
         arbitration, Landlord and Tenant agree, at Landlord's option, to enter
         into an amendment to this Lease confirming the Usable Area and the
         Rentable Area of such Phase of the Premises and the Building.
         Furthermore, all calculations set forth in the Lease based on the area
         of the Premises, including, without limitation, Base Rental, Tenant's
         Percentage Share and Landlord's Allowance for Tenant Improvement Costs,
         shall be adjusted based on the Rentable Area of the Premises and the
         Building certified by Landlord's architect-.

         1.3 TENANT'S PERCENTAGE SHARE. "Tenant's Percentage Share" means and
shall be equal to the percentage stated in the Lease Summary, or as modified in
accordance with this Lease. Landlord and Tenant acknowledge that Tenant's
Percentage Share has been obtained by dividing the Rentable Area of the Premises
by ninety-five percent (95%) of the agreed Rentable Area of the Building, and
multiplying the quotient by 100. In the event

                                       3
<PAGE>

Tenant's Percentage Share is changed during a calendar year by reason of a
change in the Rentable Area of the Premises (for example, by reason of the
occurrence of the Occupancy Date for any Phase of the Premises, as set forth
in the Lease Summary) or the Rentable Area of the Building, Tenant's
Percentage Share shall thereafter mean the result obtained by using the
revised Rentable Area in the foregoing formula. If the Tenant's Percentage
Share changes during a calendar year, Tenant's Percentage Share for the
calendar year shall be determined on the basis of the number of days during
such calendar year at each percentage share.

         1.4 "OPERATING EXPENSES" shall mean all costs paid or incurred by
Landlord in the management, operation, maintenance, repair and security of the
Building and related amenities in a prudent, businesslike and commercially
reasonable manner, including without limitation, the following:

                  (a) Costs and expenses for the maintenance and repair of the
         Building and the personal property used in connection therewith,
         including, without limitation, (i) the heating, ventilating, and air
         conditioning equipment, (ii) plumbing and electrical systems, (iii)
         light bulbs and glass, including replacement thereof, and (iv)
         elevators.

                  (b) Cleaning and janitorial costs and expenses, including
         window cleaning expenses, for the Building.

                  (c) Landscaping and grounds maintenance costs and expenses.

                  (d) Utility costs and expenses including, without limitation,
         those for electricity and other fuels and forms of power or energy,
         water charges, sewer and waste disposal, which are not separately
         metered and borne by Tenant for its own use at its election.

                  (e) Costs and expenses of redecorating, repainting, and
         recarpeting the common areas of the Building; provided, however, that,
         except as specified in subsections (f) and (j) hereof, the costs of
         structural changes to the Building which should be capitalized in
         accordance with sound accounting principles shall not be allocated or
         charged to the Premises without Tenant's prior written approval.

                  (f) Amortization (calculated as hereinafter specified) of the
         costs of all repairs, alterations, additions, changes, replacements and
         other items required by any law or governmental regulation imposed
         after the date of this Lease, including structural changes, regardless
         of whether such costs, when incurred, are classified as capital
         expenditures under generally accepted accounting principles. With
         respect to the costs described in the immediately preceding sentence
         which are capital expenditures, the amount of such capital expenditure
         shall be amortized over the useful life of the capital improvement,
         with a reasonable salvage value, all as

                                       4
<PAGE>

         determined in accordance with generally accepted accounting principles,
         with interest at the same rate as Landlord is paying for the funds to
         finance the capital improvements (or if Landlord is not financing the
         costs, then 1% above the Prime Rate). For each calendar year during the
         Lease Term which is also within the useful life of the capital
         improvement, only that amortized amount (including interest),
         determined in accordance with foregoing, shall be included in Operating
         Expenses.

                  (g) Cost of wages and salaries of all persons engaged in the
         management, operation, maintenance, repair and security of the
         Building, and so-called fringe benefits, including social security
         taxes, unemployment insurance taxes, costs for providing coverage for
         disability benefits, costs of any pensions, hospitalization, welfare or
         retirement plans, or any other similar or like expense incurred under
         the provisions of any collective bargaining agreement, costs of
         uniforms, and all other costs or expenses which the Landlord pays to or
         on behalf of employees engaged in the management, operation,
         maintenance, repair and security of the Building. This item of
         Operating Expenses shall include, without limitation, expenses, fringe
         benefits and other compensation to management personnel to the extent
         reasonably and directly allocable to the management, operation
         maintenance, repair and security of the Building.

                  (h) Charges of any independent contractor which, under
         contract with the Landlord or its manager or representatives, does any
         of the work of operating, maintaining, repairing or providing security
         for the Building.

                  (i) Legal and accounting fees and expenses, including, without
         limitation, such fees and expenses related to seeking or obtaining
         reductions in and/or refunds of Property Taxes.

                  (j) Amortization over such period of time as Landlord shall
         reasonably determine with a reasonable salvage value, and, with
         interest at a rate per annum equal to the greater of (i) the Prime Rate
         plus two percentage points or (ii) the rate Landlord is paying for
         funds borrowed for the purpose of financing the capital improvements in
         question, of capital expenditures for capital improvements made by
         Landlord after completion of the Building where such capital
         improvements are for the purpose of, or result in, reducing Operating
         Expenses, but only to the extent such Operating Expenses have been so
         reduced.

                  (k) Landlord's insurance cost and expenses for all types of
         insurance carried by Landlord with respect to the Building, provided
         that such costs and expenses with respect to insurance coverage that
         is not substantially the same as the coverage in effect on January 1,
         2001 shall be included in Operating Expenses only to the extent such
         coverage is reasonable and customary for projects similar to the
         Building located in the Midtown, Atlanta, Georgia market area.

                                       5
<PAGE>

                  (l) Security service costs and expenses.

                  (m) Management fees and expenses (not to exceed three percent
         (3%) of the gross revenue collected from Tenants of the Building, their
         agents, employees or contractors, or otherwise received with respect to
         the Building and any appurtenant facilities).

                  (n) Property Taxes.

                  (o) Such other costs, fees and expenses paid by Landlord from
         time to time, in connection with the management, operation,
         maintenance, repair and security of the Building.

Operating Expenses shall not include (i) depreciation on the Building, (ii)
tenant improvement costs, (iii) real estate brokers' commissions, (iv) interest
and capital items other than those referred to above, (v) the cost of special
services rendered to a particular tenant of the Building, which are payable by
such tenant, (vi) costs and expenses associated with the repair of latent
defects in the construction of the Building (which, by way of illustration and
not limitation, shall not include repairs due to ordinary wear and tear), (vii)
increases in Property Taxes that are directly attributable to sale of the
building, but such exclusion shall apply only if the Building were assessed at
its full fair market value prior to such sale, and (viii) those items set forth
in Exhibit "J" attached hereto and incorporated herein by this reference. If the
average occupancy level was less than ninety-five (95%) percent of the total
Rentable Area of the Building during a calendar year, the actual Operating
Expenses (exclusive of Property Taxes for this purpose only) for that calendar
year shall be adjusted to equal Landlord's reasonable estimate of Operating
Expenses had ninety-five (95%) percent of the total Rentable Area of the
Building been occupied. Landlord and Tenant acknowledge that certain of the
costs of management, operations, maintenance, repair and security of the
development from time to time shall be allocated among and shared by the owners
of two or more of the buildings in the development (including the Building). The
determination of such costs and their allocation shall be made by Landlord in
accordance with sound accounting principles. Accordingly, the term "Operating
Expenses", as used in this Lease, from time to time shall include some costs,
expenses, and taxes enumerated above which were incurred with respect to other
buildings in the development but which are allocated to and shared by the
Building in accordance with the foregoing. Notwithstanding the foregoing, Tenant
understands and agrees that its rights to use other portions of the development
of which the Building is a part are those available to the general public and
that this Lease does not grant to it additional rights of use.

Landlord will use reasonable efforts to maintain Operating Expenses consistent
with the standards of other office buildings in the Midtown, Atlanta, Georgia
market area of similar age, size and use, and shall not utilize these Operating
Expense pass-throughs for anything other than a reimbursement for actual costs
incurred to operate the Building.

         1.5 "PRIME RATE" shall mean the rate of interest announced from time to
time by Wachovia Bank of Georgia, N.A., or its successors, as its prime rate of
interest. An increase or decrease in the Prime Rate shall result in a
corresponding increase or decrease in the rate of interest being charged
hereunder and shall take effect on the day the increase or decrease in the Prime
Rate is made effective. In the event that Wachovia Bank of Georgia, N.A., or its
successors, shall abandon or abolish the practice of publishing the Prime Rate,
or should the same become unascertainable, Landlord shall designate a comparable
reference rate which shall then be deemed to be the Prime Rate under this Lease.

         1.6 "PROPERTY TAXES" shall mean the following: (a) personal property ad
valorem taxes imposed upon the furniture, fixtures, machinery, equipment,
apparatus, systems, and appurtenances used in connection with the Building for
the operation thereof; (b) real estate ad valorem taxes, assessments, impact
fees, sewer charges and transit taxes; (c) private assessments against the
Building under any private regime, and annual or special assessments and other
levies made by a community improvement district or other public or quasi-public
authority; and (d) any other federal, state, or local governmental charge,
general, special, ordinary or extraordinary (but not including income or
franchise taxes or any other taxes imposed upon or measured by Landlord's income
or profits, unless the same shall be imposed in lieu of real estate ad valorem
taxes) which may now or hereafter be levied or assessed against the Building and
the land underlying the Building or the rents derived from the Building (in the
case of special taxes or assessments which may be payable in installments, only
the amount of installments paid during a calendar year shall be included in the
taxes for that year).

                                       II.

                         TERM, ASSIGNMENT AND SUBLETTING
                         -------------------------------

         2.1 TERM.

                  (a) Tenant takes and accepts the Premises from Landlord in
         their present condition and as suited for the use intended by Tenant,
         except for such improvements as may be expressly provided for in
         Section 4.1(a), for the term described below (the "Lease Term"). The
         Lease Term shall commence on the date specified in the Lease Summary as
         the Commencement Date (the "Commencement Date"), and shall end at 6:00
         p.m. Atlanta local time on the date specified in the Lease Summary as
         the Expiration Date (the "Expiration Date").

                  (b) Landlord will deliver the Premises in phases (each a
         "Phase" and collectively, the "Phases"), with each Phase being
         delivered to Tenant pursuant to Section 4.1(a) by the "Delivery Date"
         stipulated for such Phase in the Lease

                                       7
<PAGE>

         Summary. The date upon which Tenant's obligation to pay Base Rental
         under this Lease with respect to a particular Phase is also as set
         forth in the Lease Summary as the "Base Rental Commencement Date" for
         such Phase (the "Base Rental Commencement Date")- Notwithstanding the
         foregoing, Tenant's obligation to pay Additional Rental and other
         charges under this Lease with respect to a particular Phase shall
         commence upon the date set forth in the Lease Summary as the "Occupancy
         Date" for such Phase. If for any reason whatsoever any particular Phase
         is not delivered to Tenant in the condition required pursuant to
         Section 4.1(a) below by the date stipulated in the Lease Summary as the
         "Delivery Date" for such Phase, this Lease shall not be void or
         voidable, nor shall Landlord be liable to Tenant for any resulting loss
         or damages. If Landlord is unable to deliver possession of such Phase
         by the Delivery Date for such Phase set forth in the Lease Summary for
         any reason other than delay caused by Tenant (including changes in the
         Drawings and Specifications), the Tenant shall not be obligated to pay
         Base Rental, Additional Rental or other charges under this Lease (other
         than costs for tenant improvements as provided in the Tenant
         Improvement Agreement) until a period has elapsed subsequent to the
         date such Phase is delivered to Tenant in the condition required by
         Section 4.1, which period is equal to the number of days between the
         scheduled Occupancy Date and the scheduled Delivery Date for such Phase
         as set forth in the Lease Summary; provided, however, that if Tenant
         occupies such Phase for the purpose of conducting business therefrom
         prior to expiration of such period, then Tenant's obligation to pay
         Base Rental, Additional Rental and other charges under this Lease shall
         commence on the first date of such occupancy. Furthermore, if Tenant is
         unable to occupy any Phase of the Premises because Tenant is unable to
         obtain a certificate of occupancy (or other documentation permitting
         legal occupancy) for such Phase on or after the Base Rental
         Commencement Date for such Phase, as set forth in the Lease Summary,
         which date for this purpose only shall be deferred by the number of
         days of delay due to force majeure (as described in Section 9.12) or
         delays caused by Tenant, and if the sole reason for Tenant being unable
         to obtain such certificate of occupancy (or other documentation
         permitting legal occupancy) for such Phase is any defect in the Base
         Building Condition (as that term is defined in Section 4.1) not caused
         by Tenant or its contractors in connection with the completion of
         Tenant's improvements to the Premises, then, in addition to the rent
         deferral described above, Tenant shall be entitled to a rent abatement
         equal to one (1) day of the Base Rental attributable to the portion of
         the Phase for which a certificate of occupancy (or other documentation
         permitting legal occupancy) has not issued for each day of such
         Landlord caused delay up to a maximum of thirty (30) days of delay, and
         after such thirty (30) day period, any continuing delay in Tenant's
         being able to take legal occupancy shall entitle Tenant to a rent
         abatement equal to two (2) days of the Base Rental attributable to the
         portion of the Phase for which a certificate of occupancy (or other
         documentation permitting legal occupancy) has not issued for each day
         of such continuing day of a Landlord caused delay beyond the first
         thirty (30) days of delay. Such deferral and rent abatement shall be
         Tenant's sole remedy for Landlord's

                                       8
<PAGE>

         failure to deliver possession of any Phase of the Premises. Except as
         aforesaid, no delay of possession shall operate to relieve Tenant of
         Tenant's obligations to Landlord (including the payment of rent and
         other amounts) as provided in this Lease. Notwithstanding the
         foregoing, if possession of any Phase of the Premises has not been
         delivered to Tenant within six (6) months following the Delivery Date
         for such phase set forth in the Lease Summary, for any reason
         whatsoever other than a force majeure event described in Section 9.12,
         either Landlord or Tenant, at its option at any time thereafter but
         prior to the delivery of possession, may terminate this Lease by notice
         to the other, and Landlord and Tenant shall thereupon be released from
         all obligations under this Lease; provided, however, that with respect
         only to Tenant's right to terminate pursuant to this sentence, the
         scheduled Delivery Date shall be postponed by the number of days of
         delay caused by Tenant.

         2.2 TENANT ACCEPTANCE AGREEMENT. Within twenty (20) days after the
Delivery Date for a Phase, Tenant shall execute and deliver to Landlord a
Tenant Acceptance Agreement in the form attached hereto as EXHIBIT "B". Tenant
may state in such Tenant Acceptance Agreement any defects in the Base
Building Condition (as that term is defined in Section 4.1) remaining to be
repaired or completed by Landlord, and Tenant thereby shall preserve its
objection to such listed defects. Tenant shall have waived objection to any
defects not so listed in the Tenant Acceptance Agreement except that Tenant
shall retain the right to object to latent defects not subject to detection
upon reasonable inspection of the Base Building Condition of any Phase of the
Premises prior to the Delivery Date for such Phase, provided that objections
to latent defects not disclosed in writing to Landlord within thirty (30)
days subsequent to the Delivery Date shall be deemed waived

         2.3 REMOVAL OF TENANT'S PERSONAL PROPERTY. Upon or prior to the
termination of this Lease, Tenant shall remove from the Premises and the
Building all its personal property (including, without limitation, all wiring
and cabling installed by Tenant or its contractors within the walls, ceiling or
floor of the Premises), repair any damage caused by such removal and peaceably
surrender the Premises to Landlord in the same condition as on the Occupancy
Date for each Phase, normal wear and tear excepted. Such property of Tenant not
so removed from the Premises or the Building upon the termination of this Lease
shall be considered abandoned by Tenant and may be disposed of by Landlord in
any manner whatsoever without accounting to Tenant for same or being liable in
any way to Tenant for such disposition. Upon surrender of possession of the
Premises, Tenant shall deliver to Landlord all keys to the Premises.

         2.4 HOLDING OVER . In no event shall there be any renewal of this Lease
by operation of law, and if Tenant remains in possession of the Premises after
the termination of this Lease without written authorization executed by Landlord
and Tenant, but with the acquiescence or consent of Landlord, Tenant shall be
deemed to be occupying the Premises under a month-to-month periodic tenancy at a
monthly rental equal to one hundred twenty-

                                       9
<PAGE>

five (125%) percent of the Base Rental in effect under this Lease for the full
month prior to the expiration or termination of this Lease, as set forth in the
Lease Summary, plus all Additional Rental provided for in this Lease, and
otherwise subject to all the covenants and provisions of this Lease insofar as
the same are applicable to a month-to-month periodic tenancy. Landlord and
Tenant agree that any such periodic tenancy may be terminated by thirty (30)
days prior written notice by either party to the other party, notwithstanding
any contrary provision of applicable law (the benefits of which are hereby
expressly waived). If Tenant remains in possession after termination of this
Lease without Landlord's acquiescence or consent, Tenant thereupon shall be
deemed a tenant-at-sufferance subject to summary eviction as provided by law.

         2.5 ASSIGNMENT AND SUBLEASING

                  (a) Tenant shall not, without Landlord's prior written
         consent, (i) assign, convey, mortgage, pledge, encumber, or otherwise
         transfer (whether voluntarily, by operation of law, or otherwise) this
         Lease or any interest thereunder; (ii) allow any transfer thereof or
         any lien upon Tenant's interest by operation of law; (iii) sublease the
         Premises or any part thereof; or (iv) permit the use or occupancy of
         the Premises or any portion thereof by any party other than Tenant; and
         any attempt to consummate any of the foregoing without Landlord's
         consent shall be void. Landlord hereby agrees that, subject to the
         terms and conditions of this Section 2.5, Landlord will not
         unreasonably withhold, condition or delay its consent to an assignment
         or sublease to any assignee or subtenant who is acceptable to Tenant
         (it being agreed, however, that if the holder of any mortgage, deed to
         secure debt or other similar security instrument withholds, conditions
         or delays its consent to a proposed assignment or sublease pursuant to
         a right to do so under such mortgage, deed to secure debt or other
         security instrument, then Landlord shall be deemed reasonable in
         withholding, conditioning or delaying Landlord's consent thereto).
         Contract employees or others performing services directly for Tenant
         shall not be deemed sublessees, assignees, or otherwise be subject to
         the provisions of this Section 2.5.

                  (b) Notwithstanding anything herein to the contrary, if at any
         time or from time to time during the Lease Term, Tenant desires to
         sublease all or a portion of the Premises or assign the Lease, Tenant
         shall notify Landlord in writing (hereinafter referred to in this
         Section 2.5 as the "Notice") of such desire, which notice shall contain
         (1) the name and address of the proposed subtenant or assignee and its
         form of organization, (2) the nature of the proposed subtenant's or
         assignee's business to be conducted in the Premises, (3) the terms and
         conditions of the proposed sublease or assignment, and (4) financial
         statements for the three most recent completed fiscal years of the
         proposed subtenant or assignee and. such other financial information as
         Landlord shall request, including a bank reference, together with a
         request that Landlord approve such assignment or subletting. Landlord
         shall then have the options: (i) to sublease from Tenant such space
         (hereinafter referred

                                       10
<PAGE>

         to as "Subject Space") at the same Base Rental and Additional Rental as
         Tenant is required to pay to Landlord under this Lease for the same
         space; (ii) to terminate this Lease or this Lease with respect to the
         Subject Space only; or (iii) to review such proposed assignment or
         sublease for approval or disapproval. The option to sublease, to
         terminate, or to review, as the case may be, shall be exercisable by
         Landlord in writing within a period of thirty (30) days after receipt
         of the Notice; and if Landlord fails to otherwise notify Tenant,
         Landlord shall be deemed to have elected to review such proposed
         assignment or sublease for approval or disapproval pursuant to Section
         2.5(e).

                  (c) If Landlord elects to terminate this Lease and the Subject
         Space constitutes the entire Premises, then this Lease shall terminate
         on the date set forth in Landlord's notice to Tenant, which termination
         shall be no earlier than thirty (30) and no later than ninety (90) days
         after the date of such notice. If the Subject Space does not constitute
         the entire Premises and Landlord so exercises its option to terminate
         this Lease with respect to the Subject Space, then this Lease shall
         remain in full force and effect except that the Base Rental, Rental
         Adjustment and Tenant's Percentage Share shall be reduced to conform to
         the reduced Rentable Area of the Premises.

                  (d) In the event Landlord exercises the option to sublease the
         Subject Space, the term of the subleasing from Tenant to Landlord shall
         be the term set forth in the Notice (which shall not be longer than the
         then current Lease Term unless Landlord expressly agrees in writing
         that any extension or renewal option contained in this Lease will apply
         to such Subject Space) and shall be on such terms and conditions as are
         contained in this Lease to the extent applicable, except that Landlord
         shall have the right further to sublease or assign the sublease of
         Subject Space.

                  (e) If Landlord fails to exercise either its option to
         sublease or its option to terminate within the aforesaid thirty-day
         period but elects to review the proposed assignment or sublease for
         approval or disapproval, Tenant shall submit to Landlord within twenty
         (20) days after said period a copy of the proposed assignment or
         sublease and such additional information concerning the proposed
         assignee or sublessee as may be requested by Landlord for Landlord's
         review. Within thirty-five (35) days subsequent to Landlord's receipt
         of the proposed assignment or sublease and such requested additional
         information, Landlord, in its reasonable discretion, shall approve or
         disapprove in writing the proposed assignment or sublease and the
         proposed assignee or subtenant, subject, however, to all of the
         following conditions:

                  (i)      The sublease or assignment shall be on the same terms
                           and conditions set forth in the notice given to
                           Landlord.

                                       11
<PAGE>

                  (ii)     The proposed assignee or sublessee shall engage in a
                           business in the Premises which is consistent with the
                           then standards of the Building, compatible with use
                           of the Building by other occupants thereof, and is
                           permitted by the provisions of Section 5.1 hereof,
                           and the use of the Premises or any portion thereof by
                           such subtenant or assignee will not, in Landlord's
                           estimation, increase the scope or quantity of
                           services or utilities then being furnished to Tenant
                           as of the proposed date of assignment or subletting.

                  (iii)    The proposed assignee or sublessee is of good repute
                           and of sufficient financial worth to perform its
                           obligations under this Lease or under the sublease,
                           as applicable, and Tenant shall have provided
                           Landlord with proof thereof.

                  (iv)     No subletting or assignment shall release Tenant of
                           Tenant's obligation or alter the primary liability of
                           Tenant to pay the Base Rental, Additional Rental and
                           other charges hereunder and to perform all other
                           obligations to be performed by Tenant under this
                           Lease.

                  (v)      All rental rates to be charged to any such sublessee
                           under any sublease entered into prior to December 31,
                           2001 shall not be less than the current market rates
                           for similar space leased for a similar term in the
                           Building or buildings of similar quality and grade in
                           the Midtown, Atlanta, Georgia market area, and no
                           sublessee shall have any right to assign this Lease
                           or further sublet the Premises.

                  (f) Notwithstanding the giving by Landlord of its consent to
         any assignment or sublease with respect to the Premises, no assignee or
         sublessee, other than an assignee or sublessee who is an "affiliate" of
         Tenant as provided in Section 2.5(m), may exercise any expansion
         option, preemptive right or so-called right of first refusal to lease,
         or term renewal or extension option under this Lease except in
         accordance with a separate written agreement entered into directly
         between such assignee or sublessee and Landlord. Subsequent to an
         approved assignment or sublease, the original Tenant shall have no
         right to exercise on behalf of the assignee or sublessee (as to the
         space assigned or subleased) any expansion option, preemptive right or
         so-called right of first refusal to lease or term renewal or extension
         option.

                  (g) Tenant agrees to pay to Landlord, as additional rental on
         demand, actual, reasonable costs incurred by Landlord (including,
         without limitation, any administrative fee charged to Landlord by
         Landlord's management company for the Building) (i) in connection with
         any request by Tenant for Landlord to consent to any

                                       12
<PAGE>

         assignment or subleasing by Tenant, and (ii) in providing any services
         or materials to any assignee or sublessee of Tenant.

                  (h) Any transfer or series of transfers resulting in a change
         in the controlling interest in Tenant (whether Tenant is a corporation,
         partnership, trust or other entity), whether voluntarily, by operation
         of law, or otherwise, shall be deemed an assignment of this Lease
         within the meaning of this Section 2.5, except that Tenant may merge or
         consolidate with EarthLink Network, Inc., and the entity surviving such
         transaction shall be deemed a permitted assignee under this Lease.

                  (i) In the case of an assignment or subletting, fifty percent
         (50%) of any sums or other economic consideration (for example, but not
         by way of limitation, increased rental, forgiveness of an obligation,
         or services given at no cost or at reduced cost) received by Tenant or
         its agents as a result of such assignment or subletting, whether
         denominated as consideration for the assignment, as rental under the
         sublease or otherwise, which exceed, in the aggregate, the sum of (x)
         the total sums which Tenant is obligated to pay Landlord under this
         Lease either (i) for the Premises, if the entire Premises is assigned
         or sublet, or (ii) pro rata on a square foot basis for that portion of
         the Premises assigned or sublet, if less than the entire Premises is
         assigned or sublet, plus (y) the amortized portion of market standard
         brokerage commissions, market standard tenant improvement allowances,
         market standard moving allowances and reasonable legal fees, if any,
         actually incurred by Tenant in consummating such sublease (such
         amortization to be on a straight-line basis over the remaining portion
         of the Lease Term after the rent commencement date under such
         assignment or sublease) shall be payable to Landlord as additional
         rental under this Lease without affecting or reducing any rental or
         other obligation of Tenant under this Lease.

                  (j) If. as provided herein, this Lease is assigned or the
         Premises or any part thereof is subleased or occupied by any party
         other than Tenant, Landlord may, after default by Tenant, collect rent
         from the assignee, subtenant or occupant, and apply the net amount
         collected to the Base Rental and Additional Rental herein reserved, but
         no such assignment, subleasing, occupancy or collection shall be deemed
         (i) a waiver of any of Tenant's covenants contained in this Lease, (ii)
         the acceptance by Landlord of the assignee, subtenant or occupant as
         Tenant, or (iii) the release of Tenant from further performance by
         Tenant of its covenants under this Lease.

                  (k) No assignment of or sublease under this Lease shall
         release Tenant from, or serve as a defense against, Tenant's primary
         liability under this Lease. Furthermore, Landlord's approval of or
         consent to an assignment or sublease transaction shall not affect
         Landlord's rights under this Section 2.5 as to any subsequent proposed
         assignment or sublease.

                  (l) Tenant covenants and agrees to deliver to Landlord one (1)
         fully executed counterpart of the instruments and documents (including
         amendments thereto) evidencing any approved assignment or subleasing
         effected pursuant to this Lease. Such delivery shall be made promptly
         following the execution of any such instrument or document.

                  (m) Notwithstanding anything to contrary in this Section 2.5,
         Tenant shall have the right to assign this Lease or sublet the Premises
         to any firm, person, corporation, partnership or other entity which (i)
         controls, is controlled by or is under common control with Tenant or
         (ii) if Tenant (or, if Tenant is a wholly-owned subsidiary, Tenant's
         parent company) is a public company, is deemed an "affiliate" of Tenant
         in accordance with the promulgated definition of such term under the
         rules and regulations of the Federal Securities and Exchange
         Commission, or its successor agency, provided in each of the foregoing
         instances (x) Tenant shall give notice to Landlord of the proposed
         assignment or subletting and, together with such notice, any financial
         information with respect to Tenant's affiliate, as Landlord may
         reasonably request, at least thirty (30) days in advance of the
         consummation thereof, and (y) Tenant shall not be released from
         liability under this Lease, which shall remain primary. The term
         "control," as used in the immediately preceding sentence and in Section
         2.5(m), means, with respect to a corporation, the right to the
         exercise, directly or indirectly, of more than 50% of the voting rights
         attributable to the shares of the controlled corporation, and, with
         respect to any person or entity that is not a corporation, the
         possession, directly or indirectly, of the power to direct or cause the
         direction of the management or policies of the controlled person or
         entity. As used in this Lease, an "affiliate" of Tenant shall be deemed
         an entity described in this Section 2.5(m).

         2.6 RIGHT OF RECAPTURE. THIS SECTION 2.6 SHALL BE EFFECTIVE ONLY IF
TENANT, AT ANY TIME AFTER FEBRUARY 1, 2002, CEASES TO OCCUPY AT LEAST 150,000
SQUARE FEET OF THE RENTABLE AREA IN THE BUILDING: If the Premises, or any
portion thereof in excess of 25,000 square feet of Rentable Area (whether or not
contiguous), is abandoned or deserted, or vacated for a period of more than
ninety (90) consecutive days or one hundred twenty (120) business days (whether
or not consecutive) in any twelve (12) month period, then Landlord may, at its
option, upon written notice to Tenant, terminate this Lease from time to time as
to such portion or portions of the Premises that have been so abandoned,
deserted or vacated (or any part thereof) and cause such portion or portions of
the Premises (or such part thereof) to be returned to Landlord upon demand,
without terminating the Lease as to the balance of the Premises. Following any
termination of this Lease as to a portion or portions of the Premises, Tenant
shall have no further rights with respect to such portion or portions of the
Premises, and shall immediately surrender such portion or portions of the
Premises broom-clean, with all people and property of Tenant removed therefrom,
and Tenant shall have no further obligation to pay rent with respect to such
portion or portions of the Premises, but Tenant shall continue to be liable for
all of its obligations under this Lease with respect to such portion or portions
of the Premises arising

                                       14
<PAGE>

prior to such termination and with respect to all obligations under this Lease
relating to those portions of the Premises for which this Lease has not been
terminated.

                                      III.

                                RENT AND DEPOSITS

         3.1 BASE RENTAL. Tenant shall pay to Landlord an annual base rent in
monthly installments for and during the Lease Term the amounts specified in the
Lease Summary (the "Base Rental"). The monthly installments of Base Rental
shall be paid in advance on the first day of every calendar month during the
Lease Term.

         3.2 RENTAL ADJUSTMENT. [Intentionally deleted.]

         3.3 OPERATING EXPENSES AND PROPERTY TAXES. In addition to the Base
Rental, Tenant shall pay as additional rental (the "Additional Rental"), for
each calendar year during the Lease Term, Tenant's Percentage Share (which shall
be the sum of Tenant's Percentage Share of each Phase of the Premises for which
the Occupancy Date has occurred, subject to the provisions of Section 1.3 above)
of the total Operating Expenses for the calendar year in question. The
Additional Rental payable pursuant to this Section 3.3 shall be determined and
adjusted in accordance with the following procedures:

                  (a) During each December of the Lease Term, or as soon
         thereafter as practicable, Landlord shall give Tenant written notice of
         its estimate of Additional Rental payable under this Section 3.3 for
         the ensuing calendar year. On or before the first day of each month
         during the ensuing calendar year, Tenant shall pay to Landlord 1/12 of
         such estimated amounts together with the Base Rental, provided that if
         such notice is not given in December Tenant shall continue to pay
         during the ensuing calendar year on the basis of the amounts payable
         during the calendar year just ended, until the month after such notice
         is given. If at any time or times it appears to Landlord that the
         actual amount payable under this Section 3.3 for the current calendar
         year will vary from Landlord's estimate by more than 5%, Landlord may
         revise, by notice to Tenant, its estimate for such year, and subsequent
         payments by Tenant for such year shall be based upon such revised
         estimate. Failure to make a revision contemplated by the immediately
         preceding sentence shall not prejudice Landlord's right to collect the
         full amounts of Additional Rental payable under this Section 3.3.
         Notwithstanding the foregoing, for calendar year 2000, estimated
         payments of Additional Rental payable under this Section 3.3 shall be
         made at the rate of Six and 75/100 Dollars ($6.75) per square foot of
         Rentable Area of each Phase of the Premises for which the Occupancy
         Date has occurred during calendar year 2000. Such amount shall not
         constitute a floor or otherwise

                                       15
<PAGE>

         have any bearing upon the amount of estimated payments for any calendar
         year subsequent to calendar year 2000.

                  (b) Within one-hundred and twenty (120) days after the close
         of each calendar year during the Lease Term, or as soon after such
         120-day period as practicable, Landlord shall deliver to Tenant a
         statement of the adjustments to be made pursuant to this Section 3.3
         for the calendar year just ended certified by certified public
         accountants designated by Landlord, and such statement shall be final
         and binding upon Landlord and Tenant absent manifest error. If on the
         basis of such statement Tenant owes an amount of Additional Rental that
         is less than the estimated payments for the calendar year just ended
         previously made by Tenant, Landlord shall credit such excess to the
         next payments of Additional Rental coming due pursuant to this Section
         3.3 or, if the term of this Lease is about to expire, refund such
         excess to Tenant if Tenant is not in default under this Lease (in the
         instance of an event of default such excess shall be held as additional
         security for Tenant's performance, may be applied by Landlord to cure
         any such event of default, and shall not be refunded until any such
         event of default is cured). If on the basis of such statement Tenant
         owes an amount of Additional Rental that is more than the estimated
         payments for the calendar year just ended previously made by Tenant,
         Tenant shall pay the deficiency to Landlord within thirty (30) days
         after delivery of the statement.

                  (c) If the Lease term shall expire on a day other than the
         last day of a calendar year, the amount of Additional Rental payable
         pursuant to this Section 3.3 shall be the product of multiplying the
         Additional Rental which otherwise would have been payable for the full
         calendar year by a fraction, the numerator of which is the actual
         number of days of the calendar year in question included within the
         Lease Term, and the denominator of which is 365. The expiration of this
         Lease shall not affect the obligations of Landlord and Tenant pursuant
         to subsection (b) of this Section 3.3 to be performed subsequent to
         such expiration.

                  (d) Notwithstanding anything in this Section 3.3 of this Lease
         to the contrary, Tenant's Percentage Share of increases in
         "controllable" Operating Expenses (as that term is hereinafter defined)
         for any calendar year shall not include a portion of such
         "controllable" Operating Expenses for such year to the extent the
         amount of such "controllable" Operating Expenses exceeds the product of
         (i) "controllable" Operating Expenses for the immediately preceding
         calendar year, multiplied by (ii) 105%. For the purposes of this
         subsection (d), "controllable" Operating Expenses are defined to be all
         Operating Expenses other than taxes, utility costs, cost of labor that
         is provided directly or indirectly through a contractor at or near
         minimum wage, and insurance costs. For avoidance of doubt, Tenant's
         obligations with respect to increases in Property Taxes shall not be
         subject to the limitations set forth in this subsection (d).

                                       16
<PAGE>

                  (e) Within one hundred twenty (120) days after Tenant receives
         the annual statement of adjustment described in subsection (b) above,
         Tenant may contest the statement by written notice to Landlord, which
         notice shall specify the particular areas of Operating Expenses that
         Tenant desires to contest; provided, however, that no such contest
         shall entitle Tenant to withhold or delay amounts due to Landlord as
         set forth in Landlord's statement. If no such contest is made by
         written notice to Landlord delivered within such 120-day period, such
         statement shall be binding upon Tenant in all respects. If Tenant
         timely contests such statement, Tenant shall have the right to inspect
         and examine, at reasonable times during normal business hours,
         Landlord's books of account and records pertaining to the Operating
         Expenses of the Building for the calendar year in question and for the
         immediately preceding calendar year, all at Tenant's sole cost and
         expense. Such inspection shall be conducted by an independent certified
         public accountant who in no event is compensated on a contingent fee
         basis. Such inspection shall be conducted in Landlord's office in
         Atlanta, Georgia, at Tenant's expense, and shall be completed within
         five (5) business days after such inspection is commenced, with written
         notice to Landlord of the results thereof, by no later than forty-five
         (45) days after the date of Tenant's notice of contest delivered to
         Landlord pursuant to the foregoing provisions of this subsection (e);
         any matters not specifically disputed in a written notice timely filed
         with Landlord after such audit has been completed shall be final and
         binding upon Tenant in all respects. Landlord may have an agent or
         employee present during such inspection and audit. If the contest
         ultimately results in Landlord and Tenant agreeing that Tenant has
         overpaid Landlord for its share of Operating Expenses, such overpayment
         shall be refunded by Landlord to Tenant within thirty (30) days after
         the date such contest is so resolved. Furthermore, if a review by
         Tenant disclosed a discrepancy of greater than five percent (5%) in any
         category of Operating Expenses (a "Material Discrepancy") for the year
         being reviewed, then Tenant shall have the right to review Landlord's
         records of Operating Expenses for such category for the four (4)
         calendar years immediately prior to the calendar year in which the
         Material Discrepancy occurred, but not any calendar year prior to
         calendar year 2000.

         3.4 COMMITMENT DEPOSIT. [Intentionally deleted.]

         3.5 SECURITY DEPOSIT. [Intentionally deleted.]

         3.6 PAYMENTS. Tenant shall pay to Landlord all Base Rental, additional
rent, and all other charges due and owing by Tenant under this Lease without
deduction or set off, in legal tender, and at Landlord's address specified in
the Lease Summary or as otherwise directed from time to time by Landlord.

         3.7 RENT FOR PARTIAL MONTHS. A prorated monthly installment, based on
a thirty (30) day month, shall be paid in advance (i) on the Commencement Date
for any fraction of a month if the Lease Term begins on any day other than the
first day of any

                                       17
<PAGE>

month and (ii) on the first day of the final month of the Lease Term for any
fraction of a month if the Lease Term shall terminate on any day other than the
last day of any month.

                                      IV.

                PREPARATION, MAINTENANCE AND REPAIR OF PREMISES

         4.1 PREPARATION OF THE PREMISES.

                  (a) Landlord shall deliver each Phase of the Premises to
         Tenant in the condition required for such Phase when delivered, as
         follows:

                  Phase 1  "As Is" condition, provided that (other than with
                           respect to the areas shown on EXHIBIT "A" hereto as
                           the "Terrace Level - Phase I" and the "Print Shop")
                           all prior tenant improvements therein shall have been
                           demolished and removed by Landlord, at its expense
                  Phase 2  "As Is" condition, provided that (other than with
                           respect to the area shown on EXHIBIT "A" hereto as
                           "Phase IIB") all prior tenant improvements therein
                           shall have been demolished and removed by Landlord,
                           at its expense
                  Phase 3  Base Building Condition (in process on Delivery Date)
                  Phase 4  Base Building Condition (completed on Delivery Date)
                  Phase 5  Base Building Condition (completed on Delivery Date)

         As used in this Lease, the term "Base Building Condition" shall mean
         the condition described in Attachment "C-1" attached to and
         incorporated into this Lease. Said Attachment "C-1" is also a part of
         the Tenant Improvement Agreement attached as EXHIBIT "C" to this Lease
         and made a part hereof by this reference (the "Tenant Improvement
         Agreement").

                  (b) Tenant shall construct or install in the Premises the
         Tenant Improvements, as defined in and to be constructed or installed
         pursuant to the provisions of the Tenant Improvement Agreement. Tenant
         agrees to comply with all of the terms and provisions of the Tenant
         Improvement Agreement, including, without limitation, the obligation to
         pay, as additional rental, all amounts due Landlord under Section 3
         thereof according to the payment procedures contained therein. Landlord
         acknowledges that Tenant intends to increase the floor loading capacity
         of the Terrace Level and the first (1st) floor of the Building in
         certain areas and to install a conduit zone completely enclosed by
         concrete block that would be of sufficient size to permit passageway
         for persons as well as for seven (7) six inch (6")

                                       18
<PAGE>

         conduits plus seven (7) four inch (4") conduits, and that the foregoing
         improvements are essential components of Tenant's operations in the
         Building. Landlord agrees that it will be reasonable in working with
         Tenant, at no cost to Landlord, to accomplish these features for the
         Building. In connection therewith, Tenant expressly acknowledges and
         agrees that:

                  (i) Any and all costs incurred in connection with making any
                  such improvements shall be deemed Tenant Improvement Costs for
                  purposes of Exhibit "C' to this Lease;

                  (ii) If any such improvements required by Tenant compromise
                  the marketability of any other leaseable space in the
                  Building, such space shall be included in the Premises and
                  leased by Tenant pursuant to the terms of this Lease;

                  (iii) If such improvements eliminate or compromise any parking
                  spaces in the on-site Parking Facility, such spaces shall be
                  leased by Tenant as part of its parking allotment under
                  Section 9.15 of this Lease;

                  (iv) Any such improvements required by Tenant must comply with
                  applicable laws, codes, ordinances, rules and regulations; and

                  (v) Tenant will remove any such improvements upon the
                  expiration or earlier termination of this Lease, if requested
                  to do so by Landlord.

         In addition to the foregoing, as part of the initial construction of
         Tenant Improvements to the Premises, Tenant may submit to Landlord
         requests respecting the location of sprinklers in the Premises, and
         Landlord agrees to cooperate reasonably with Tenant in connection with
         such relocation as long as (i) such request is received sufficiently in
         advance of the installation of any sprinklers for Landlord to
         accommodate Tenant's request without delay in completion of the
         Building renovation, (ii) any such location of sprinklers must comply
         with applicable laws, codes, ordinances, rules and regulations, and
         (iii) any incremental costs incurred by Landlord as a result of any
         such location or relocation of sprinklers in order to accommodate
         Tenant (over the cost Landlord would have incurred in the absence of
         such request) shall be a part of the Tenant Improvement Costs for
         purposes of Exhibit "C" to this Lease.

                  (c) If Tenant causes the Tenant Improvements to exceed in
         value the value of the Base Building Condition PLUS Landlord's
         Allowance for Tenant Improvement Costs (as such term is defined in the
         Tenant Improvement Agreement), and if the installation or construction
         of such Tenant Improvements

                                       19
<PAGE>

         causes an increase in the ad valorem taxes on the Building, then Tenant
         shall pay from time to time, as additional rental, any such increase in
         act valorem taxes on demand of Landlord.

                  (d) Tenant acknowledges that any space delivered to Tenant in
         "as is" condition will be subject to some renovation work by Landlord
         after such delivery in order to remove existing restrooms and convert
         such space to Usable Area and to complete renovations to other portions
         of the Building. At present the scope of this work is as described in
         the plans referenced in EXHIBIT "I" hereto, and the estimated time for
         completion of work sufficient for Tenant's occupancy is August, 2000,
         with additional work (including, without limitation, bathroom
         renovation) estimated to be completed by December 1, 2000. Landlord
         shall complete such work on a timely basis and in a good and
         workmanlike manner, and shall be responsible for any repairs thereto.
         Any entry by Landlord into the Premises to complete such work shall be
         governed by Section 4.9 of this Lease. In addition to the renovation
         work to the Premises described above, Tenant acknowledges that the
         Building will be undergoing a major renovation from and after the date
         this Lease is executed, which renovation is projected to be
         substantially completed in August, 2000. In consideration of the
         disruption of Tenant's operations resulting from such renovation work,
         Landlord has agreed to allow Tenant to occupy the Premises until August
         1, 2000 without any charge for Base Rental. Landlord agrees to complete
         the Building renovations in substantial accordance with the plans
         described on EXHIBIT "I" hereto (which plans Tenant hereby approves),
         subject to change orders issued during the course of renovation work
         that do not materially vary the overall design, construction or level
         of finishes from those shown in the aforesaid plans and renderings.

         4.2 REPAIRS BY TENANT. Tenant shall at its own expense keep the
Premises in good repair and tenantable condition and indemnify Landlord against
any loss, damage, or expense arising by reason of any failure of Tenant so to
keep the Premises in good repair and tenantable condition or due to any act or
neglect of Tenant, its agents, employees, contractors, invitees, licensees,
tenants, or assignees. If Tenant fails to perform, or cause to be performed,
such maintenance and repairs, then at the option of Landlord, in its sole
discretion, any such maintenance or repair may be performed or caused to be
performed by Landlord and the cost and expense thereof charged to Tenant, and
Tenant shall pay the amount thereof to Landlord on demand as additional rental.

         4.3 REPAIRS BY LANDLORD. Landlord shall maintain in good order and
repair, subject to normal wear and tear, casualty and condemnation, the Building
(excluding the Premises and other portions of the Building leased to other
tenants), including without limitation, public areas, the parking lot and
landscaped areas, elevators, stairs, corridors, common restrooms, the
mechanical, plumbing and electrical systems and the structure itself (including
the glass exterior surfaces of the Premises). The cost of any such repairs or
maintenance to the foregoing necessitated by the intentional acts or omissions,
negligence

                                       20
<PAGE>

or gross negligence of Tenant, or its agents, employees, contractors, invitees,
licensees, tenants or assignees, however, shall be reimbursed by Tenant to
Landlord upon demand as additional rental.

         4.4 ALTERATIONS BY TENANT. Tenant shall make no alterations or
additions of any kind in or to the Premises without first obtaining
Landlord's prior written consent. Such consent may be granted or withheld in
Landlord's sole discretion; provided, however, Landlord agrees it will not
unreasonably withhold its consent to cosmetic or non-structural alterations
or additions which do not involve structure, walls, floors, Building systems,
electrical installations or the obtaining of building permits or otherwise
result directly or indirectly in Landlord incurring any costs not paid by
Tenant in full. Except as may otherwise be agreed by Landlord in writing at
the time of granting its consent, all such work, including additions,
fixtures, and Tenant Improvements (but excluding moveable office furniture
and equipment and other personal property of Tenant) made or placed in or
upon the Premises by either Tenant or Landlord shall be and become the
Landlord's property at the termination of this Lease by lapse of time or
otherwise, all without compensation or payment to Tenant. Approved
alterations or additions made by Tenant shall be at the sole expense and
liability of Tenant, and Tenant's indemnity in Subsection 7.3(d) hereof shall
apply to any contractors engaged by Tenant in connection therewith. Landlord
shall have the right to take depreciation with respect to the Tenant
Improvements to the extent of the Landlord's Allowance and Tenant shall have
the right to take depreciation with respect to Tenant Improvements to the
extent that it contributes towards the cost of Tenant Improvements in excess
of Landlord's Allowance. If at the time of Landlord's approval of the plans
for any tenant improvements to the Premises after the initial Tenant
Improvements are completed pursuant to Section 4.1(b) of this Lease, Tenant
requests in writing that Landlord designate which, if any, of such tenant
improvements Landlord will require Tenant to remove at Tenant's expense prior
to the expiration or earlier termination of this Lease, Tenant shall not be
obligated to remove any of such tenant improvements from the Premises, except
to the extent such removal is required in writing at the time of Landlord's
approval of such plans in response to such request from Tenant.

         4.5 DISCHARGE OF LIENS . Tenant is not authorized to contract for or on
behalf of Landlord for work on or the furnishing of materials to the Premises or
any other part of the Building. Tenant shall discharge of record by payment,
bond or otherwise, within ten (10) days subsequent to the date of its receipt of
notice thereof from Landlord, any mechanic's, laborer's or similar lien filed
against the Premises or the Building for work or materials claimed to have been
furnished at the instance of Tenant. If Tenant shall fail to cause such lien or
claim of lien to be so discharged or bonded within such period, in addition to
any other right or remedy it may have, Landlord may, but shall not be obligated
to, discharge the same by paying the amount claimed to be due or by procuring
the discharge of such lien or claim by deposit in court or bonding, and in any
such event, Landlord shall be entitled, if Landlord so elects, to compel the
prosecution of any action for the foreclosure of such lien or claim by the
claimant and to pay the amount of the judgment, if any, in favor of the

                                       21
<PAGE>

claimant, with interest, costs and allowances, Tenant shall pay as additional
rental on demand from time to time any sum or sums so paid by Landlord and all
costs and expenses incurred by Landlord, including, but not limited to,
attorneys' fees in processing such discharge or in defending any such action.

         4.6 DAMAGE AND DESTRUCTION.

                  (a) If the Building or Premises is damaged partially or wholly
         by fire, the elements, act of God or other casualty, and if such damage
         cannot, in Landlord's reasonable estimation, be materially restored
         within ninety (90) days of such damage, then Landlord may, at its sole
         option, terminate this Lease as of the date of such fire or casualty
         and the Lease Term shall end an such date as if that date had been
         originally fixed in this Lease for the expiration of the Lease Term.
         Landlord shall exercise its option provided herein by written notice to
         Tenant within sixty (60) days of such fire or other casualty.

                  (b) If this Lease is not terminated pursuant to subsection (a)
         above, then Landlord shall proceed with all due diligence to repair and
         restore the Building or Premises, as the case may be (except that
         Landlord may elect not to rebuild, and thus terminate this Lease, if
         such damage occurs during the last year of the Lease Term, regardless
         of any term renewal option which is unexercised at the date of
         occurrence of the casualty). Landlord's obligation to restore the
         Premises under the preceding sentence shall be discharged upon
         Landlord's restoration of the Premises to Base Building Condition, as
         defined in EXHIBIT "C" hereto. Tenant shall be responsible for
         restoration of Tenant Improvements utilizing its own funds, without
         allowance or reimbursement from Landlord. If Landlord shall fail to
         complete such repairs and material restoration within one hundred fifty
         (150) days after the date of such damage and Tenant's use and enjoyment
         of the Premises is then materially impaired by the uncompleted
         restoration, 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, or because of 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 150-day
         period for restoration, repair, or rebuilding shall be extended for the
         amount of time Landlord is so delayed. In no event shall Landlord be
         required to rebuild, repair, or replace any personal property,
         equipment or trade fixtures which belong to Tenant.

                  (c) If this Lease is not terminated by Landlord pursuant to
         this Section 4.6 and if the Premises are unfit for occupancy in whole
         or in part following such damage, the Base Rental and Rental Adjustment
         payable during the period in which the Premises are unfit for occupancy
         shall abate for the period from the date

                                       22
<PAGE>

         of such casualty until the earlier of sixty (60) days after Landlord
         completes its restoration work or the date Tenant resumes occupancy of
         the Premises for the purpose of conducting business therefrom, and
         Tenant's Percentage Share shall be reduced for such period in
         proportion to the number of square feet of Rentable Area of the
         premises rendered unusable by such damage; provided, however, that no
         such abatement and reduction shall be made under the provisions of this
         subsection (c) in excess of the amount of rent insurance proceeds
         actually collected by Landlord and directly attributable to rent loss
         under this Lease (taking into account rent loss under all other leases
         of space in the Building) in the event such damage shall have been
         caused through the negligence or willful misconduct of Tenant, its
         agents, employees, contractors, invitees, licensees, tenants or
         assignees.

                  (d) in the event of any damage or destruction to the Building
         or the Premises, Tenant shall, upon notice from Landlord, remove
         forthwith, at its sole cost and expense, such portion or all of the
         property belonging to Tenant (other than partitions, fixtures,
         additions and similar improvements), from such portion or all of the
         Building or the Premises as Landlord shall request and Tenant agrees to
         indemnify and hold Landlord harmless from any loss, liability, costs,
         and expenses, including attorneys' fees, arising out of any claim of
         damage or injury as a result of any alleged failure by Tenant to secure
         properly the Premises following such damage or destruction and prior to
         such removal.

                  (e) 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 Landlord's insurance may be subject to control by
         the holder or holders of any indebtedness secured by a mortgage or deed
         to secure debt covering any interest of Landlord in the Premises or the
         Building.

                  (f) 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 or Building requires that any
         insurance proceeds be paid to it, such that restoration of the Building
         cannot be performed, then Landlord shall have the right to terminate
         this Lease by delivering written notice of termination to Tenant within
         thirty (30) days after such requirement is made by any such holder,
         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.

                  (g) If any such casualty stated in this Section 4.6 occurs,
         Landlord shall not be liable to Tenant for inconvenience, annoyance,
         loss of profits, expenses, or any other type of injury or damage
         resulting from the repair of any such damage, or from any repair,
         modification, arranging, or rearranging of any portion of the

                                       23
<PAGE>

         Premises or any part or all of the Building or for termination of this
         Lease as provided in this Section 4.6.

         4.7 EMINENT DOMAIN.

                  (a) If all or any substantial part of the Building or of the
         Premises 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 the use of the Premises for the
         purpose for which it is then being used, 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 Lease Term.

                  (b) If part of the Building or Premises is 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
         subsection (a) above, this Lease shall not terminate but the Base
         Rental and Rental Adjustment payable hereunder during the unexpired
         portion of this Lease and Tenant's Percentage Share 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 immediately prior to such taking as is reasonably
         feasible under the circumstances.

                  (c) Tenant 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, to the extent
         provided by law, separately claim against and receive from the
         condemning authority, if legally payable, compensation for Tenant's
         removal, relocation costs, loss of business, business interruption and
         loss of trade fixtures, but only if and to the extent no such claim or
         award therefor will reduce or affect Landlord's awards.

                  (d) Notwithstanding anything to the contrary contained in this
         Section 4.7, if during the Lease Term the use or occupancy of any part
         of the Building or Premises shall be taken or appropriated temporarily
         for any public or quasi-public use under any governmental law,
         ordinance, or regulation, or by right of eminent domain, this Lease
         shall be and remain unaffected by such taking or appropriation and
         Tenant shall continue to pay in full all rental payable hereunder by
         Tenant during the Lease Term. 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 loss of use
         or occupancy of the Premises during the Lease Term, and Landlord shall
         be entitled to receive that portion of any award

                                       24
<PAGE>

         which represents the cost of restoration and compensation for the loss
         of use or occupancy of the Premises after the end of the term of this
         Lease.

         4.8 REPORTS OF DEFECTS. Tenant shall report to Landlord immediately in
writing any damage to or defective condition in or about the Building or
Premises known to Tenant.

         4.9 LANDLORD'S RIGHT TO ENTER PREMISE. Tenant shall not change the
locks on any entrance to the Premises or install additional locks without
Landlord's prior written consent, which consent shall be in Landlord's sole
discretion. Upon Tenant's written request to Landlord, Landlord will make a
reasonable change of locks on behalf of Tenant and at Tenant's sole cost and
expense. Landlord and its agents, employees and contractors shall have the right
to enter the Premises at such times as Landlord deems reasonably necessary to
make necessary repairs, additions, alterations and improvements to the Building,
including, without limitation, the erection, use and maintenance of pipes and
conduits and repairs to adjacent promises or other premises and the renovations
contemplated by Section 4. 1(d) above or by the Tenant Improvement Agreement.
Landlord shall also be allowed to take into and through the Premises any and all
needed materials that may be required to make such repairs, additions,
alterations and improvements, all without being liable to Tenant in any manner
whatsoever. During such time as work is being carried on in or about the
Premises, provided such work is carried out in a manner so as not to interfere
unreasonably with the conduct of Tenant's business therein, the rent provided
herein shall in no wise abate, and Tenant waives any claim and cause of action
against Landlord for damages by reason of loss or interruption to Tenant's
business and profits therefrom because of the prosecution of any such work or
any part thereof. In addition, upon reasonable notice to Tenant (which may be
oral), Landlord and its agents, employees and contractors shall have the right
to enter the Premises during normal business hours, without undue interference
with the conduct of Tenant's business therein, to inspect and examine the
Premises and to exhibit the Premises to prospective purchasers, tenants and
lenders. In the event of emergency, or if otherwise necessary to prevent injury
to persons or damage to property, such entry to the Premises may be made by
force without any liability whatsoever on the part of Landlord for damage
resulting from such forcible entry.

                                       V.

                                USE AND SERVICES
                                ----------------

         5.1 USE. Tenant shall use the Premises for the purposes stated in
the Lease Summary and for no other purpose. Tenant shall not use the Premises
for any illegal purpose, nor violate any statute, regulation, rule or order
of any governmental body in its use thereof, nor create or allow to exist any
nuisances or trespasses, nor do any act in or about the Premises or bring
anything onto or into the Premises which will in any way increase the rate of
insurance on the Premises nor deface or injure the Premises or overload the
floor of the Premises.

                                       25
<PAGE>

         5.2 SERVICES. Provided no event of default shall have occurred under
this Lease, Landlord agrees to provide to Tenant, as Landlord deems reasonably
necessary, the following services:

                  (a) General cleaning and janitorial service required as a
         result of normal, prudent use of the Premises and completion in
         accordance with the basic Janitorial Specifications provided in Exhibit
         "G," performed by a service selected by Landlord, and only on Mondays
         through Fridays, inclusive, with New Year's Day, Martin Luther King
         Day, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and
         Christmas Day (herein collectively called the "Holidays") excepted.
         Notwithstanding the foregoing, Tenant may take over all responsibility
         for cleaning Tenant's Premises by giving Landlord not less than sixty
         (60) days advance notice of such election, in which event (i) Landlord
         shall not charge Tenant for any janitorial costs as Operating Expenses
         other than such costs as are incurred to clean and maintain common
         areas of the Building and the Building structure; and (ii) Landlord
         shall have no further obligation respecting janitorial service to the
         Premises;

                  (b) Heating and air-conditioning service daily on Mondays
         through Fridays, inclusive, with Holidays excepted, from 8:00 A.M. to
         7:00 P.M. and on Saturdays, if not a Holiday, from 8:00 A.M. to 1:00
         P.M. Landlord reserves the right to prohibit the use of machines and
         equipment which generate heat in their operation that put excessive
         demands on Landlord's base building air-conditioning system unless and
         until arrangements are made by Tenant, acceptable to Landlord, to
         obtain and install in the Premises at Tenant's cost supplementary
         air-conditioning equipment, and the cost of operation and maintenance
         of such equipment shall be paid by Tenant on the Base Rental payment
         dates at such rates as are established from time to time by Landlord.
         Notwithstanding the foregoing, if Tenant provides for such supplemental
         air conditioning at its expense, as aforesaid, in accordance with
         Landlord's requirements and plans and specifications approved by
         Landlord, Landlord will not object to Tenant's use of Tenant's
         computer equipment, other office machinery and computer rooms in the
         Premises as shown on the drawings and specifications approved by
         Landlord from time to time in accordance with this Lease, to the extent
         such equipment, machinery and rooms are adequately serviced, in
         Landlord's reasonable judgment, by such supplemental air conditioning.
         Should Tenant desire either heating or air-conditioning at times when
         such services are not furnished by Landlord under the terms of this
         Lease, Landlord may elect, entirely at its option, to furnish such
         services as requested by Tenant upon not less than 24 hours notice from
         Tenant. Such service shall be provided at an hourly charge of
         FORTY-FIVE and N0/100 DOLLARS ($45.00) per hour per building (i.e.,
         north wing or south wing of the Building) (subject to increase from
         time to time to reflect actual increases in the cost to landlord of
         providing such services to Tenant), which charges Tenant shall promptly
         pay upon invoice from

                                       26
<PAGE>

         Landlord. Payments for such additional services shall be deemed
         additional rental due from Tenant;

                  (c) Outside air ventilation for the Building to provide 20
         cfm per person (assuming a design condition of one person per 142
         rentable square feet) in accordance with ASHRAE Standard 62-1989.
         Landlord agrees to maintain fresh air within the Premises in compliance
         with ASHRAE Standard 62-1989.

                  (d) Passenger and freight elevator service to all floors of
         the Building on which the Premises are located daily on Mondays through
         Fridays, inclusive, with Holidays excepted, from 8:00 A.M. to 7:00 P.M.
         and on Saturdays, if not a Holiday, from 8:00 A.M. to 1:00 P.M. At
         least one elevator shall be operative at all other hours. A freight
         elevator will be available at all hours, subject to scheduling with
         Landlord and Tenant's paying any reasonable costs actually incurred by
         Landlord associated with Tenant's use of the freight elevator outside
         of normal operating costs;

                  (e) Landlord shall furnish electric current in a quantity
         sufficient to ensure that Tenant has constant access to and ability to
         use a minimum of seven (7) watts per usable square foot of the Premises
         for small business machinery only from electric circuits designated by
         Landlord for Tenant's use, exclusive of Building standard tenant
         lighting and HVAC. Such circuits will be fed into one or more of the
         existing electrical panels (a 480/277 volt panel or panels for Building
         standard tenant lighting and a 208/120 volt panel or panels for tenant
         outlet requirements) in the electrical closet or closets located on the
         same Building floor as the Premises. Tenant's usage of said panels on
         any given floor shall not exceed Tenant's pro rata share (based on
         rentable square footage) of the panels' capacity. Tenant shall not use
         any electrical equipment which in Landlord's opinion will overload the
         wiring installations or interfere with the reasonable use thereof by
         other users in the Building. Tenant shall not install or operate in the
         Premises any electric power generation equipment or transformer
         carrying substantial non-linear loads, producing above-average amounts
         of heat, or not having the capability of neutralizing harmonic
         distortion. Tenant shall not, without Landlord's prior written consent
         in each instance, which consent shall not be unreasonably withheld,
         connect any items such as non-Building standard tenant lighting,
         vending equipment, printing or duplicating machines, computers (other
         than desktop word processors and personal computers), auxiliary air
         conditioners, and other computer related equipment to the Building's
         electrical system, or make any alteration or addition to the system.
         If Tenant desires any such items, additional 208/120 volt electrical
         power beyond that supplied by Landlord as provided above, electric
         current in excess of 208/120 volts for purposes other than Building
         standard tenant lighting, or other special power requirements or
         circuits, then Tenant may request Landlord to provide such supplemental
         power or circuits to the Premises. If Landlord furnishes any special
         power or circuits, Tenant shall pay Landlord, on demand, the cost of
         the

                                       27
<PAGE>

         design, installation and maintenance of the facilities required to
         provide such additional or special electric power or circuits, and the
         cost of all electric current so provided at a rate not to exceed that
         which would be charged by Georgia Power Company, or its successor, if
         Tenant were a direct customer thereof. Landlord may require separate
         electrical metering of such supplemental electric power or circuits to
         the Premises, and Tenant shall pay, on demand, the cost of the design,
         installation and maintenance of such metering facilities. In no event
         shall Tenant have access to any electrical closets in the Building, it
         being agreed that any electrical engineering design or contract work
         shall be performed at Tenant's expense by Landlord or an electrical
         engineer and/or electrical contractor designated by Landlord. With
         respect to any proposed separate metering or electrical surcharge
         Tenant shall have the right to have its own engineer review such
         proposal to confirm for Tenant the reasonableness thereof. All invoices
         respecting the design, installation and maintenance of the facilities
         requested by Tenant shall be paid within thirty (30) days of Tenant's
         receipt thereof. Landlord's charge to Tenant for the cost of electric
         current so provided shall be paid within thirty (30) days of receipt of
         invoice by Tenant; and

                  (f) Common use restrooms, toilets, and drinking fountains
         available on each floor or partial floor of the Building occupied by
         Tenant.

                  (g) Landlord shall provide security services for the Building,
         the Common Areas and the parking facility for the Building specified in
         Section 9.15(a) of this Lease (the "Parking Facility") consisting of
         the following:

                  (i) Subject to compliance with applicable laws, codes,
                  ordinances, rules and regulations, Landlord shall install, at
                  Landlord's sole cost, a security system (the "Security
                  System") consisting of (i) a "card-key" access system on all
                  exterior doors of the Building, all doors providing entry to
                  the Premises and all elevators operating after hours and (ii)
                  security cameras (monitored 24 hours a day, 7 days per week)
                  that are located in locations reasonably agreed upon by
                  Landlord and Tenant. Such Security System must permit the use
                  of the fire stairwells for emergency exiting in accordance
                  with applicable codes and any requirements Landlord may
                  impose. Landlord shall provide Tenant with any keys or codes
                  necessary to access the Premises after installation of the
                  Security System and Tenant may coordinate its security system
                  with Landlord's security system.

                  (ii) Landlord will make reasonable efforts, at no cost to
                  Landlord, to coordinate with Tenant during the planning stage
                  of the renovation of the Building concerning the integration
                  of Landlord's and Tenant's security systems.

                  (iii) At least two (2) uniformed guards, one of which shall be
                  stationed in the main entrance lobby and the other of which
                  shall cruise the Building and the on-site Parking Facility
                  during the times that such services are customarily and
                  generally furnished in comparable office buildings in the
                  Midtown, Atlanta, Georgia market area. One (1) such guard
                  shall, if available, escort Tenant's employees to/from
                  vehicles in the on-site Parking Facility of the Building upon
                  Tenant's request. One of the guards may be designated by
                  Tenant, but Tenant hereby releases, indemnifies and holds
                  harmless Landlord with respect to any and all liability
                  arising from any incident in which the guard designated by
                  Tenant is involved.

         Notwithstanding the foregoing, Tenant acknowledges that: (x) Landlord
         and its agents, employees and contractors cannot guaranty the security
         of the Building, the Common Areas, or the Parking Facility, (y)
         Landlord shall not be liable for the willful misconduct, gross
         negligence or negligence of other tenants or third parties including,
         without limitation, vandalism, theft, mysterious disappearances and
         damage to property or person; and (z) Tenant, for itself and its
         agents, employees, business invitees and licensees, releases Landlord
         and its agents, employees and contractors from any and all loss, cost
         or damage that Tenant, or its agents, employees, business invitees or
         licensees may suffer or incur as a result of the matters described in
         clause (y) above.

                  (h) Tenant shall be afforded access to its Premises on a
         24-hour-per-day basis, although such access may be subject to the Rules
         and Regulations and reasonable security measures.

                                       VI.

                              COMPLIANCE WITH LAWS

         6.1 TENANT'S COMPLIANCE WITH LAWS. Tenant shall comply, at its own
expense, with all statutes, regulations, rules, ordinances, and orders of any
governmental body, department, or agency thereof which apply to or result from
Tenant's use or occupancy of the Premises and shall abide by and observe the
Rules and Regulations attached to this Lease as EXHIBIT "D" and such other rules
and regulations for the use, occupancy, or operation of the Building as may
hereafter be established in writing by Landlord.

         6.2 RENT CONTROL. Tenant waives the benefit of all existing and future
rent control laws and similar governmental rules and regulations, whether in
time of war or not, to the full extent permitted by law.

                                       29

         6.3 BUILDING ALTERATIONS. If, in order to maintain the Building as an
office building or otherwise, Landlord shall be required by any governmental
authority to repair, alter, remove, construct, reconstruct, or improve any part
or all of the Building or Premises, Tenant's obligations under this Lease will
not be affected and Tenant waives all claims for injury, damage, or abatement of
rent because of such repair, alteration, removal, construction, reconstruction,
or improvement, or lack thereof; provided, however, that if such action by
Landlord shall render the Premises partially or wholly unfit for occupancy and
if, in Landlord's reasonable estimation, it cannot complete such acts within
ninety (90) days, then at the option of Landlord to be exercised by giving
written notice to Tenant within sixty (60) days following the date of notice to
Landlord by such governmental authority, this Lease shall terminate on the date
of such election and Tenant shall immediately surrender the Premises to
Landlord. In such event Tenant shall continue to owe and pay rent and other
charges up to but not beyond the time of such surrender. If Landlord shall elect
not to terminate this Lease as provided above, Landlord and Tenant shall have
the same respective rights and obligations as provided above in Sections 4.6(b)
and (c), and the provisions of Section 4.6(g) shall apply regardless of whether
or not Landlord elects to terminate this Lease.

         6.4 TAXES PAYABLE BY TENANT. In addition to Base Rental and other
charges to be paid by Tenant hereunder, Tenant shall reimburse Landlord upon
demand for any and all taxes payable by Landlord whether or not now customary or
within the contemplation of the parties hereto, to the extent not included in
Property Taxes: (a) upon, measured by or reasonably attributable to the cost or
value of Tenant's equipment, furniture, fixtures and other personal property
located in the Premises or by the cost or value of any improvements made in or
to the Premises by Tenant regardless of whether title to such improvements shall
be in Tenant or Landlord; (b) upon or measured by the rental payable hereunder
in the nature of a sales tax upon rent or a so-called "rent tax", but not
federal or state income taxes of Landlord; and (c) upon this transaction or any
document to which Tenant is a party creating or transferring an interest in the
Premises. In the event that it shall not be lawful for Tenant so to reimburse
Landlord, the monthly rental payable to Landlord under this Lease shall be
revised to net Landlord the same net rental after imposition of any such tax
upon Landlord as would have been payable to Landlord if such tax had not been
imposed

                                      VII.

                    INSURANCE, LIABILITY AND INDEMNIFICATION

         7.1 INSURANCE.

                  (a) Tenant agrees to carry fire and extended coverage
         insurance insuring Tenant's interest in its improvements and
         betterments to the Premises, including, without limitation, the Tenant
         Improvements, and any and all furniture,

                                       30
<PAGE>

         equipment, supplies, and other property owned, leased, held, or
         possessed by it and contained therein, such insurance coverage to be
         in an amount equal to the full insurable value of such improvements and
         property. 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.

                  (b) Tenant also agrees to carry a policy or policies of
         worker's compensation and comprehensive general liability insurance,
         including personal injury and property damage, with contractual
         liability endorsement, in the amount of Five Hundred Thousand Dollars
         ($500,000.00) for property damage and One Million Dollars
         ($1,000,000.00) per occurrence for personal injuries or deaths of
         persons occurring in or about the Premises. Said policies shall: (i)
         name Landlord as an additional insured and insure Landlord's contingent
         liability under this Lease, (ii) be issued by an insurance company
         which is reasonably acceptable to Landlord and licensed to do business
         in the State of Georgia, and (iii) provide that said insurance shall
         not and may 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.

                  (c) Landlord shall, carry fire and extended coverage insurance
         for the completed Building (excluding land, foundations and other
         uninsurable components) and on-site Parking Facility (except that
         Landlord shall have no obligation to maintain insurance as to tenant
         improvements), in such amount as is required by the holder of a first
         priority deed to secure debt encumbering the Building (or, if none, in
         an amount that prudent landlords of first class office buildings in the
         Midtown, Atlanta, Georgia market area would ordinarily and customarily
         carry); provided, however, that Landlord shall be entitled to
         self-insure pursuant to a bona fide self-insurance program as to all or
         any portion of the risk of loss that would otherwise by insured by the
         aforesaid insurance coverage. For purposes of Section 7.2 of this
         Lease, Landlord's waiver of subrogation and release of Tenant for
         liabilities covered by insurance shall extend to liabilities otherwise
         required under this Lease to be insured against but with respect to
         which Landlord has elected to self-insure in whole or in part, as well
         as liabilities encompassed by the insurance coverage maintained by
         Landlord.

         7.2 WAIVER OF SUBROGATION AND RELEASE . Landlord and Tenant shall
obtain from their respective insurers under all policies of fire, theft and
other property damage insurance maintained by either of them at any time during
the term of this Lease insuring or covering the Building or any portion thereof
or personal property or operations therein, a waiver of all rights of
subrogation which the insurer of one party might have against the other party,
and Landlord and Tenant shall each indemnify the other against any loss or
expense, including reasonable attorney's fees, resulting from the failure to
obtain such waiver.

                                       31
<PAGE>

         Landlord and Tenant, to the fullest extent permitted by law, each
waives all rights of recovery against the other, and releases the other from
liability, for loss or damage to the extent (but only to the extent) of the sum
of (i) the deductible amount under the applicable insurance policy (or, in the
case of self-insurance by Landlord, the amount of deductible customarily
maintained in the Midtown, Atlanta, Georgia market area by prudent landlords of
buildings comparable to the Building insuring similar risks), plus (ii) either
the collected insurance proceeds received by the party suffering such loss or
damage or, in the case of self-insurance by Landlord, the amount of insurance
proceeds that would have been paid with respect to such loss had Landlord
maintained the insurance coverage otherwise required under Section 7.1 of this
Lease; provided, however, that if either Landlord or Tenant fails to obtain
and/or maintain in full force and effect the insurance coverage required of such
party under Section 7.1(c) hereof (including without limitation the required
waivers of subrogation and the required naming of Landlord as an additional
insured) other than (in the case of Landlord only) pursuant to a bona fide
self-insurance program that complies with Section 7.1, the party so failing to
maintain and/or obtain insurance coverage (the "failing party") shall
nevertheless waive and release (and shall be deemed to have waived and released)
the other party (the "non-failing party") from its liability as set forth above,
as fully as if the failing party had not so failed to obtain and/or maintain
such insurance coverage, but the non-failing party shall in such event not waive
or release (or be deemed to have waived or released) any obligation or liability
of the failing party to the non-failing party.

         7.3 INDEMNITY . Tenant agrees to indemnify and hold Landlord harmless
from and defend Landlord against any and all claims or liability for any injury
or death to any person or damage to any property whatsoever:

                  (a) either (i) occurring in, on or about the Premises, or (ii)
         occurring in, on, or about any facilities (including, without
         limitation, elevators, stairways, passageways or hallways) the use of
         which Tenant may have in conjunction with other tenants of the
         Building, when such injury, death or damage shall be caused by the act,
         neglect or fault of, or omission of any duty with respect to the same,
         by Tenant, its agents, employees, contractors, invitees, licensees,
         tenants, or assignees;

                  (b) arising from any work or thing whatsoever done by or on
         behalf of Tenant in or about the Premises or from transactions of the
         Tenant concerning the Premises;

                  (c) arising from any breach or event of default on the part of
         the Tenant in the performance of any covenant or agreement on the part
         of the Tenant to be performed pursuant to the terms of this Lease, or

                  (d) otherwise arising from any act or neglect of the Tenant,
         or any of its agents, employees, contractors, invitees, licensees,
         tenants or assignees.

                                       32
<PAGE>

         7.4 LIABILITY OF LANDLORD . Except as otherwise provided herein,
Landlord shall be liable to Tenant for direct damages proximately occasioned by
the negligence or intentional acts of Landlord, its agents and employees acting
within the scope of their agency or employment, but not for consequential or
speculative damages such as business loss. Landlord shall not be liable to
Tenant or to any person, firm, corporation or other business association
claiming by, through or under Tenant, for failure to furnish or for delay in
furnishing any service provided for in this Lease, and no such failure or delay
by Landlord shall be an actual or constructive eviction of Tenant nor shall any
such failure or delay operate to relieve Tenant from the prompt and punctual
performance of each and all the covenants to be performed herein by Tenant; nor
for defects in the cooling, heating, electric, water, elevator, or other
apparatus or systems or for water discharged from sprinkler systems in the
Building; nor for the theft, mysterious disappearance, or loss of any property
of Tenant whether from the Premises or any part of the Building. Landlord agrees
to make reasonable efforts to protect Tenant from interference or disturbance by
third persons, including other tenants; however, Landlord shall not be liable
for any interference, disturbance or act whether caused by another tenant or
tenants of Landlord or other person, nor shall Tenant be relieved from any
obligation herein because of such interference, disturbance or act.

         Notwithstanding the provisions of this Section 7.4 to the contrary, if
Landlord fails to furnish or delays in furnishing any essential Building service
Landlord is obligated to provide under this Lease (including water, electricity,
sewer, elevators, HVAC and restrooms) for any reason other than a reason beyond
Landlord's control, Tenant shall be entitled to abate Base Rental until the
service is restored, but only under the following terms and conditions:

                  (a) The loss of service must be of a material nature so as to
         render the Premises substantially unusable for the purposes
         contemplated by this Lease for a period of not less than three (3)
         consecutive days after the notice described in clause (b) below is
         given by Tenant to Landlord;

                  (b) At the time of the lose of service, Tenant must give
         written notice promptly to Landlord of the loss of service and its
         claim for abatement under this Section 7.4 and Tenant only shall be
         entitled to abatement of Base Rental, assuming all other conditions of
         this Section 7.4 are satisfied, if such notice is timely given to
         Landlord;

                  (c) Landlord may prevent or stop abatement by providing
         substantially the same service by temporary or alternative means until
         the cause of the loss of service can be corrected; and

                  (d) In no event shall Tenant be entitled to any abatement of
         rent as a result of (i) any loss of service as a result of an event
         contemplated under any of

                                       33
<PAGE>

         Sections 4.4, 4.6 or 4.7 of this Lease or (ii) any loss of service to
         any area outside of the Premises if such loss of service is not
         essential to the customary use and enjoyment of the Premises by
         Tenant.

Landlord agrees to use commercially reasonable efforts to restore any essential
Building services.

         7.5 LIMITATION OF LIABILITY. Landlord's obligations and liability with
respect to this Lease shall be limited solely to Landlord's interest in the
Building, as such interest is constituted from time to time, and neither
Landlord (beyond its interest in the Building) nor any officer, director,
shareholder or partner of Landlord shall have any personal liability whatsoever
with respect to this Lease. In any action or proceeding brought to enforce the
obligation of Landlord to Tenant under this Lease, Landlord and Tenant agree
that any final judgment or decree shall be enforceable against Landlord only to
the extent of Landlord's interest in the Building, as aforesaid, and any such
judgment or decree shall not be capable of execution against, nor be a lien on,
any assets of Landlord other than its interest in the Building, as aforesaid.

                                      VIII.

                   EVENT OF DEFAULT AND RELATED REQUIREMENTS
                   -----------------------------------------

         8.1 DEFAULT AND REMEDIES

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

                  (i) The Base Rental or Additional Rental is not paid when due,
                  and such failure of payment shall continue for more than ten
                  (10) days subsequent to the date of receipt by Tenant of
                  written notice of non-payment from Landlord, provided that
                  Landlord shall not be obligated to provide such notice and
                  opportunity to cure more than two (2) times in any calendar
                  year during the Lease Term, and the third or any subsequent
                  occasion of a failure to pay Base Rental or Additional Rental
                  when due during any such calendar year shall constitute a
                  Default. No right to receive notice or cure period in favor of
                  Tenant shall affect Tenant's obligation to pay late fees or
                  interest under Section 8.3 for having failed to make timely
                  payment of a monetary obligation;

                  (ii) Any other sum of money payable under this Lease is not
                  paid when due, and such failure of payment shall continue for
                  more than thirty (30) business days subsequent to the date of
                  receipt by Tenant of written notice

                                       34
<PAGE>

                  of non-payment from Landlord, provided that Landlord shall not
                  be obligated to provide such notice and opportunity to cure
                  more than two (2) times in any calendar year during the Lease
                  Term, and the third or any subsequent occasion of such failure
                  during any such calendar year shall constitute a Default. No
                  right to receive notice or cure period in favor of Tenant
                  shall affect Tenant's obligation to pay late fees or interest
                  under Section 8.3 for having failed to make timely payment of
                  a monetary obligation;

                  (iii) [Intentionally deleted.]

                  (iv) [Intentionally deleted.]

                  (v) Tenant's interest in the Lease or the Premises shall be
                  subjected to any attachment, levy, or sale pursuant to any
                  order or decree entered against Tenant in any legal proceeding
                  and such order or decree shall not be vacated within thirty
                  (30) days of entry thereof;

                  (vi) Tenant breaches or fails to comply with any of the Rules
                  and Regulations in EXHIBIT "D" hereto, as the same may
                  hereafter be amended from time to time, and such breach or
                  failure shall continue for more than thirty (30) days
                  subsequent to the date of receipt by Tenant of written notice
                  of such breach or failure from Landlord;

                  (vii) Tenant breaches or fails to comply with any other term,
                  provision, condition, or covenant of this Lease, and such
                  breach or failure shall continue for more than thirty (30)
                  days subsequent to the date of receipt by Tenant of written
                  notice of such breach or failure from Landlord (if the matter
                  in question is not reasonably susceptible of cure by Tenant
                  within the thirty-day period, then Tenant shall have such
                  additional time as may reasonably be necessary, as set forth
                  in a schedule for such curative action reasonably agreed upon
                  by Landlord and Tenant during such thirty (30) day period,
                  provided that Tenant institutes the curative action within the
                  thirty-day period and prosecutes the same diligently to
                  completion); provided, however, that if such breach or failure
                  by Tenant is of such a nature as to create an emergency
                  condition (which, for this purpose, shall mean a condition
                  that poses an immediate threat to the safety or security of
                  persons or property, a nuisance to other tenants of the
                  Building as to which a tenant has registered a complaint with
                  Landlord, a breach or default condition (or a condition that,
                  with notice or passage of time, or both, would constitute a
                  breach or default) under any loan or other agreement between
                  Landlord and a third party, or any condition adversely
                  affecting the structural integrity or systems of the
                  Building), such event shall constitute a default immediately
                  upon Landlord giving Tenant notice thereof, but

                                       35
<PAGE>

                  Landlord shall not have the right to terminate this Lease by
                  reason of such default by Tenant (notwithstanding anything in
                  Section 8.1(b) to the contrary), but Landlord may, in addition
                  to any other remedies hereunder, cure such default for and on
                  behalf of Tenant, and at Tenant's expense, and receive from
                  Tenant the reasonable cost of such curative action incurred by
                  Landlord, as additional rent, together with interest thereon
                  at the rate set forth in Section 8.3 hereof from the date such
                  cost is incurred to the date reimbursed by Tenant; or

                  (viii) Tenant, if a corporation, joint venture, partnership,
                  limited partnership or trust, without Landlord's prior written
                  consent and the written assumption of this Lease by another
                  party approved by Landlord, both in Landlord's sole
                  discretion, shall be dissolved (except that a dissolution in
                  connection with a permitted assignment or subletting as set
                  forth in Section 2.5 (m) or Tenant's merger with Earth Link
                  shall not constitute a Default).

                  (b) Upon the occurrence of a Default, Landlord shall have the
         option to do and perform any one or more of the following in addition
         to, and not in limitation of, any other remedy or right permitted it at
         law or in equity or by this Lease (but subject to clause (vii) of
         Section 8.1(a) above):

                  (i) Landlord, with or without terminating this Lease, may
                  immediately or at any time thereafter reenter the Premises and
                  perform, correct or repair any condition which shall
                  constitute a failure on Tenant's part to keep, observe,
                  perform, satisfy, or abide by any term, condition, covenant,
                  agreement, or obligation of this Lease or of the Rules and
                  Regulations now in effect or hereafter adopted, and Tenant
                  shall fully reimburse and compensate Landlord on demand for
                  all costs and expenses incurred by Landlord in such
                  performance, correction or repairing, including accrued
                  interest as provided in the next sentence. All sums so
                  expended to cure Default shall accrue interest from the date
                  of demand until date of payment at a rate of interest which is
                  the lower of (x) a per annum rate equal to the Prime Rate
                  plus two percent, or (y) sixteen (16%) percent per annum, but
                  in no event at a rate higher than that permitted by applicable
                  law.

                  (ii) Landlord, with or without terminating this Lease, may
                  immediately or at any time thereafter demand in writing that
                  Tenant vacate the Premises and thereupon Tenant shall vacate
                  the Premises and remove therefrom all property thereon
                  belonging to or placed on the Premises by, at the direction
                  of, or with consent of Tenant within ten (10) days of receipt
                  by Tenant of such notice from Landlord, whereupon Landlord
                  shall have the right to reenter and take possession of the

                                       36
<PAGE>

                  Premises. Any such demand, reentry and taking possession of
                  the Premises by Landlord shall not of itself constitute an
                  acceptance by Landlord of a surrender of this Lease or of the
                  Premises by Tenant and shall not of itself constitute a
                  termination of this Lease by Landlord.

                  (iii) Landlord, with or without terminating this Lease, may
                  immediately or at any time thereafter reenter the Premises
                  and remove therefrom Tenant and all property belonging to or
                  placed on the Premises by, at the direction of, or with
                  consent of Tenant. Any such reentry and removal by Landlord
                  shall not of itself constitute an acceptance by Landlord of a
                  surrender of this Lease or of the Premises by Tenant and shall
                  not of itself constitute a termination of this lease by
                  Landlord.

                  (iv) Landlord, with or without terminating this Lease, may
                  immediately or at any time thereafter relet the Premises or
                  any part thereof for such time or times, at such rental or
                  rentals and upon such other terms and conditions as Landlord
                  in its sole discretion may deem advisable, and Landlord may
                  make any alterations or repairs to the Premises which it may
                  deem necessary or proper to facilitate such reletting; and
                  Tenant shall pay all costs of such reletting including but not
                  limited to the cost of any such alterations and repairs to the
                  Premises, attorneys' fees, and brokerage commissions; and if
                  this Lease shall not have been terminated, Tenant shall
                  continue to pay all rent and all other charges due under this
                  Lease up to and including the date of beginning of payment of
                  rent by any subsequent tenant of part or all of the Premises,
                  and thereafter Tenant shall pay monthly during the remainder
                  of the term of this Lease the difference, if any, between the
                  rent and other charges collected from any such subsequent
                  tenant or tenants and the rent and other charges reserved in
                  this Lease, but Tenant shall not be entitled to receive any
                  excess of any such rents collected over the rents reserved
                  herein.

                  (v) Landlord may immediately or at any time thereafter
                  terminate this Lease, and this Lease shall be deemed to have
                  been terminated upon receipt by Tenant of written notice of
                  such termination. Upon such termination Landlord shall have
                  the right to recover from Tenant, as liquidated damages, the
                  following:

                           (A)      the worth, at the time of the award, of the
                                    unpaid rent that is due and payable at the
                                    time of termination of this Lease; and

                           (B)      the worth, at the time of the award, of the
                                    amount by which the unpaid rent that would
                                    have been earned after the date of
                                    termination of this Lease until the time of
                                    the award

                                       37
<PAGE>

                                    exceeds the amount of rent that could have
                                    been reasonably obtained by Landlord using
                                    reasonable diligence and good faith efforts
                                    to relet the Premises; and

                           (C)      the worth, at the time of the award, of the
                                    amount by which the unpaid rent for the
                                    balance of the Lease Term (or the then
                                    current extension period) after the time of
                                    the award exceeds the amount of rent that
                                    could have been reasonably obtained by
                                    Landlord using reasonable diligence and good
                                    faith efforts to relet the Premises; and

                           (D)      any other amount and court costs necessary
                                    to compensate Landlord for all detriment
                                    directly caused by Tenant's failure to
                                    perform its obligations under this Lease;
                                    provided Tenant shall never have any
                                    liability or responsibility whatever for any
                                    consequential or indirect damages

                           Any amount due Landlord for future rent obligations
                  under subsection (C) above may, at Tenant's option, be paid
                  immediately in cash, or in lieu thereof, Tenant may give
                  Landlord its promissory note in the face amount due Landlord,
                  which shall be payable by Tenant to Landlord, in equal monthly
                  principal installments together with interest on the unpaid
                  principal for a term equal to what would have been the
                  remaining portion of the Lease Term (or the then current
                  extension period). Payment of such note shall be guaranteed in
                  writing in a form and by a guarantor which are reasonably
                  acceptable to Landlord.

                           The following words and phrases as used in this
                  Section 8.1(b)(v) shall have the following meanings;

                           (x) The "worth at the time of the award" as used in
                           Section 8.1(b)(v)(A) and (B) shall be computed by
                           allowing interest at the lesser of (a) the Prime Rate
                           plus three percent (3%) or (b) the maximum rate
                           permitted by law.

                           (y) The "worth at the time of the award" as used in
                           Section 8.1(b)(v)(C) shall be computed by
                           discounting the amount at the discount rate of the
                           Federal Reserve Bank of Atlanta at the time of the
                           award, plus two percent (2%); and

                           (z) The term "time of the award" shall mean either
                           the date upon which Tenant pays to Landlord the
                           amount recoverable by Landlord as set forth above or
                           the date of entry of any

                                       38

                           determination, order or judgment of any court,
                           whichever first occurs.

                  (vi) Landlord may exercise all remedies granted a "Secured
                  Party" under the Georgia Uniform Commercial Code. Landlord
                  shall have a lien upon all goods, chattels or personal
                  property of any description belonging to Tenant which are
                  placed in, or become a part of, the Premises, as security for
                  the performance by Tenant of its obligations under this Lease,
                  which lien shall not be in lieu of or in any way affect any
                  statutory landlord's lien given by law, but shall be
                  cumulative thereto; and Tenant hereby grants to Landlord a
                  security interest in all such property placed in the Premises,
                  which shall be subject to rights of Tenant's lenders or others
                  providing financing for such property. In the event Landlord
                  exercises its option to terminate this Lease, or to reenter
                  and relet the Premises as provided herein, Landlord may at its
                  option take possession of all of Tenant's property on the
                  Premises and sell the same at public or private sale after
                  giving Tenant reasonable notice of the time and place of any
                  public sale, or of the time after which any private sale is to
                  be made, for cash or on credit, or for such prices and terms
                  as Landlord deems best, with or without having the property
                  present at such sale. In addition, Landlord may at its option
                  foreclose this lien in the manner and form provided by the
                  foreclosure of security instruments or in any other manner
                  permitted by law. The proceeds of any such foreclosure or sale
                  shall be applied first to the necessary and proper expense of
                  removing, storing and selling such property, including
                  reasonable attorney's fees, then to the payment of any
                  indebtedness, other than rent, due hereunder from Tenant to
                  Landlord, including interest thereon, then to the payment of
                  any rent or other sums due or to become due under this Lease,
                  with the balance, if any, to be paid to Tenant.

                  (c) If Landlord reenters the Premises or terminates this Lease
         pursuant to any of the provisions of this Lease, Tenant hereby waives
         all claims for damages which may be caused by such reentry or
         termination by Landlord. Tenant shall and does hereby agree to
         indemnify and hold Landlord harmless from any loss, cost (including
         court costs and attorneys' fees), or damages suffered by Landlord by
         reason of such reentry or termination. No such reentry or termination
         shall be considered or construed to be a forcible entry.

                  (d) No course of dealing between Landlord and Tenant or any
         failure or delay on the part of Landlord in exercising any rights of
         Landlord under this Section 8.1 or under any other provisions of this
         Lease shall operate as a waiver of any rights of Landlord hereunder or
         under any other provisions of this Lease, nor shall any waiver of a
         Default an one occasion operate as a waiver of any subsequent Default
         or of any other Default. No express waiver shall affect any condition,

                                       39
<PAGE>

         covenant, rule, or regulation other than the one specified in such
         waiver and that one only for the time and in the manner specifically
         stated.

                  (e) The exercise by Landlord of any one or more of the rights
         and remedies provided in this Lease shall not prevent the subsequent
         exercise by Landlord of any one or more of the other rights and
         remedies herein provided. All remedies provided for in this Lease are
         cumulative and may, at the election of Landlord, be exercised
         alternatively, successively, or in any other manner and are in addition
         to any other rights provided for or allowed by law or in equity.

         8.2 INSOLVENCY OR BANKRUPTCY. The making by Tenant of an assignment for
the benefit of its creditors, the appointment under state law of a receiver to
take possession of all or substantially all of Tenant's assets, or the voluntary
or involuntary involvement of Tenant as a principal in a state law insolvency or
reorganization proceeding, may, at the option of Landlord, be deemed and
declared a Default by Tenant hereunder. Tenant covenants and agrees promptly to
notify Landlord in writing of (i) the occurrence of any of the events described
in the preceding sentence or any event similar thereto, whether occurring in
Georgia or any other jurisdiction, and (ii) the institution by or against Tenant
of any proceeding under the United States Bankruptcy Code including a copy of
the petition filed to initiate such proceeding.

         8.3 LATE PAYMENTS . Tenant shall pay, in the event Base Rental,
Additional Rental, or other charge to be paid by Tenant hereunder is not paid
when due, (A) a late fee of five (5%) percent of the amount past due, which
late fee Tenant acknowledges is an agreed reimbursement to Landlord for the
administrative expense incurred by Landlord as a result of Tenant's late payment
and not a penalty; and (B) interest on the amount past due (excluding late
fees) at a rate (the "Default Rate") which is the lower of (x) a per annum rate
equal to the Prime Rate plus three percent, or (y) sixteen (16%) percent per
annum, but in no event at a rate higher than that permitted by applicable law,
from due date until paid. Should Tenant make a partial payment of past due
amounts, the amount of such partial payment shall be applied first, to late
fees, second, to accrued but unpaid interest, and third, to past due amounts,
in inverse order of their due date.

         8.4 ATTORNEYS' FEES FOR COLLECTION . If any Base Rental, Additional
Rental or other debt owing by Tenant to Landlord hereunder is collected by or
through an attorney-at-law, Tenant agrees to pay an additional amount, as
attorneys' fees, Landlord's actual reasonable costs thereof. In connection with
any payment of attorneys' fees and costs pursuant to this Section 8.4, Landlord
and Tenant hereby waive any right either might have under O.C.G.A. Section
13-1-11 respecting the determination of such attorneys' fees and costs.

         8.5 WAIVER OF HOMESTEAD - Tenant hereby waives and renounces all
homestead or exemption rights which Tenant may have under or by virtue of the
Constitutions and Laws of the United States of America, the State of Georgia,
and any other State as against

                                       40
<PAGE>

any debt or sum Tenant may owe Landlord under this Lease and hereby transfers,
conveys, and assigns to Landlord all homestead or exemption rights which may be
allowed or set apart to Tenant, including such as may be set apart in any
bankruptcy proceeding to pay any debt or sum owing by Tenant to Landlord
hereunder.

         8.6 NO WAIVER OF RIGHTS. No failure or delay of either party to
exercise any right or power given it herein or to insist upon strict compliance
by the other party of any obligation imposed on it herein and no custom or
practice of either party hereto at variance with any term hereof shall
constitute a waiver or a modification of the terms hereof by either party or any
right it has herein to demand strict compliance with the terms hereof by the
other party. Neither party has or shall have any authority to waive any
provision of this Lease unless such waiver is expressly made in writing.

         8.7 LANDLORD'S DEFAULTS. Notwithstanding any other provision of this
Lease to the contrary, in the event of any default by Landlord under this Lease,
Tenant will give Landlord written notice specifying such default with
particularity, and Landlord shall then have thirty (30) days in which to cure
any such default; provided, however, in the event any such default cannot with
reasonable diligence be cured within such thirty-day period, Landlord shall have
such additional reasonable period of time as is necessary to cure such default
so long as Landlord commences such cure within such thirty-day period and shall
diligently prosecute in good faith such cure to completion. Unless and until
Landlord fails to so cure any default after such notice, Tenant shall not have
any remedy or cause of action by reason thereof. If Landlord fails to cure such
default prior to the expiration of such cure period, then Tenant may give an
additional notice to Landlord and upon the expiration of ten (10) days after
such second notice without such default having been cured, Tenant may cure such
default, all on behalf of and at the expense of Landlord, and do all necessary
work and make all necessary payments in connection therewith. Landlord shall pay
Tenant the reasonable amount actually incurred by Tenant, together with interest
thereon at the Default Rate from the date of payment until re-payment, within
thirty (30) days after notice from Tenant that such cost has been incurred
together with supporting invoices evidencing the amount of such cost. If
Landlord fails to pay the amount requested by Tenant within such thirty (30) day
period, then Tenant may withhold up to twenty-five percent (25%) of each payment
of Base Rental thereafter due to Landlord to satisfy the payment of such
indebtedness (with such offset to be applied first to accrued and unpaid
interest); provided, however, that Tenant shall be entitled to increase such
withholding up to one hundred percent (100%) of any and all such payments of
Base Rental to Landlord at such time that the unpaid and unapplied amount of
such indebtedness (including accrued, unpaid interest) equals or exceeds
seventy-five percent (75%) of the remaining unpaid Base Rental obligations
payable for the balance of the then current term of this Lease. Notwithstanding
the foregoing, in the event Landlord notifies Tenant that Landlord disputes
Tenant's allegation of a Landlord default under this Lease (such notice to be
given prior to the expiration of the cure period afforded Landlord, as recited
above, with respect to such alleged default), then Landlord shall have the right
to institute an arbitration proceeding in accordance with the provisions of
EXHIBIT "F" hereto within ten (10) days after

                                       41
<PAGE>

the effective date of such dispute notice, in such case, Tenant shall not
exercise the foregoing "self-help" rights (except in an emergency), nor shall
Landlord be liable for any expenses incurred by Tenant in connection therewith,
nor shall Tenant make any offset against Base Rental, until (in each case) such
time as all such arbitration proceedings are completed. All reasonable
attorneys' fees and arbitration costs in any such proceeding which are incurred
by the prevailing party shall be paid by the other party. If the holder of a
properly recorded first mortgage or deed to secure debt has notified Tenant, in
writing, that it is the holder of such lien on the Premises and shall so
request, then Tenant shall provide such holder with a duplicate copy of any
notice sent to Landlord covering a default hereunder and such holder shall be
granted sixty (60) days after receipt thereof (as such time period may be
extended beyond such 60-day period as reasonably necessary to correct or remedy
such default, so long as such holder commences such corrective action within
such 60-day period and thereafter diligently pursues the same to completion), to
correct or remedy such default (provided, however, that such holder shall
provide written notice to Tenant on or before the thirty-first (31st) day after
receipt of Tenant's notice of default as to whether such holder intends to cure
said default).

                                       IX.

         9.4 SUBORDINATION AND ATTORNMENT.

                  (a) Except as provided in subsections (c) and (d) below, and
         subject to subsection (e) below, this Lease and all rights of Tenant
         hereunder are and shall be subject and subordinate to (i) the lien,
         title and interest of any first-in-priority mortgage, first-in-
         priority deed to secure debt, first-in-priority deed of trust, or other
         first-in-priority instrument in the nature thereof which may now or
         hereafter affect Landlord's estate or interest in and to the Building
         or the land underlying the Building and to any other first-in-priority
         instrument encumbering the fee title of the Building or the land
         underlying the Building and to any modifications, renewals,
         consolidations, extensions, or replacements thereof; and (ii) all
         ground leases which may hereafter be executed affecting the Building or
         the land underlying the Building.

                  (b) Subsection (a) above shall be self-operative, and no
         further instrument of subordination shall be required by the holder of
         any such instrument affecting or encumbering the Building or the land
         underlying the Building. In confirmation of such subordination, Tenant
         shall, upon demand, at any time or times, execute, acknowledge and
         deliver to Landlord or the holder of any such mortgage, deed to secure
         debt, deed of trust, or other instrument or to the lessor under any
         such ground lease, without expense, any and all instruments that may
         be requested by Landlord or such holder or such lessor to evidence the
         subordination of this Lease and all rights hereunder to any such
         mortgage, deed to secure debt, deed of trust, or other instrument or
         the grant of any such ground lease, and each such renewal,
         modification, consolidation, replacement, and extension thereof.

                                       43
<PAGE>

                  (c) Tenant shall, upon demand of Landlord, at any time or
         times, execute, acknowledge, and deliver to Landlord or to the holder
         of any mortgage, deed to secure debt, deed of trust, or other
         instrument affecting or encumbering the Building or the land underlying
         the Building or to the lessor under any ground lease affecting, the
         Building or the land underlying the Building, without expense, any and
         all instruments that may be necessary to make this Lease superior to
         any such mortgage, deed to secure debt, deed of trust or other
         instrument or the grant of any such ground lease, and each renewal,
         modification, consolidation, replacement, and extension thereof.

                  (d) If the holder of any mortgage, deed to secure debt, deed
         of trust or other instrument affecting or encumbering the Building or
         the land underlying the Building or if the lessor under any ground
         lease affecting the Building or the land underlying the Building shall
         hereafter succeed to the rights of Landlord under this Lease, whether
         through possession or foreclosure action or exercise of private power
         of sale or delivery of a new lease, Tenant shall, at the option of such
         holder or lessor, attorn to and recognize such successor as Tenant's
         landlord under this Lease as of the date of such succession to
         Landlord's interest and shall promptly execute and deliver any
         instrument that may be necessary to evidence such attornment. Upon such
         attornment, this Lease shall continue in full force and effect as a
         direct lease between such successor Landlord and Tenant, subject to all
         of the terms, covenants, and conditions of this Lease.

                  (e) Notwithstanding the foregoing, Tenant's agreement in
         Section 9.4(a) above is expressly conditioned upon Landlord obtaining,
         at no cost to Landlord, from any lessor under a future ground lease or
         the holder of any future mortgage or security deed encumbering the
         Building a commercially reasonable agreement (a "Nondisturbance
         Agreement") stating that such lessor or holder, as the case may be,
         will not disturb Tenant's occupancy of the Premises in the event of a
         foreclosure of such mortgage or security deed or a termination of such
         ground lease, provided there is not a Default under this Lease.
         Landlord shall be deemed to have satisfied such condition under this
         Section 9.4(e) if Landlord delivers to Tenant a Nondisturbance
         Agreement to Tenant for signature on such lessor's or holder's form of
         subordination, nondisturbance and attornment agreement as proposed by
         such lessor or holder to be used with respect to this Lease, so long as
         such form sets forth the nondisturbance covenant required by this
         Section 9.4(e) and is consistent with commercially reasonable standards
         for such agreements as generally used in Atlanta, Georgia. Tenant
         hereby expressly approves a Nondisturbance Agreement in the form
         attached as EXHIBIT "K' hereto. Landlord agrees to deliver a
         Nondisturbance Agreement substantially in the form of EXHIBIT "K'
         executed by Landlord and Landlord's existing mortgagee within thirty
         (30) days after the date of this Lease.

<PAGE>

                  (f) In the event of any conflict between the terms and
         conditions of this Lease and the terms and conditions of any
         Nondisturbance Agreement executed by both Landlord and Tenant, the
         terms of such Nondisturbance Agreement shall control.

                  (g) Landlord hereby represents and warrants that Landlord has
         not entered into any mortgage, deed to secure debt or ground lease with
         respect to the Building subsequent to September 1, 1998.

         9.5 ESTOPPEL CERTIFICATE . At any time and from time to time, Tenant,
on or before the date specified in a request therefor made by Landlord, which
date shall not be earlier than ten (10) days from the making of such request,
covenants and agrees to execute, acknowledge and deliver to Landlord a
certificate evidencing (i) whether or not this Lease is in full force and
effect, (ii) whether or not this Lease has been amended in any manner, and if so
specifying such amendment or amendments, (iii) whether or not there are any
existing events of default on the part of Landlord hereunder to the knowledge of
Tenant and specifying the nature of such events of default, if any, and (iv) the
date to which rent, and other amounts due hereunder, if any, have been paid.
Each certificate delivered pursuant to this Section may be relied on by any
prospective purchaser or transferee of Landlord's interest hereunder or of any
part of Landlord's property or by any mortgagee of Landlord's interest hereunder
or of ANY part of Landlord's property or by an assignee of any such mortgagee or
by any ground lessor of Landlord's interest hereunder.

         9.6 SEVERABILITY . If any clause or provision of this Lease is or
becomes illegal, invalid or unenforceable because of present or future laws or
any rule or regulation of any governmental body or entity, effective during the
Lease Term, the intention of the parties hereto is that the remaining parts of
this Lease shall not be affected thereby, unless the lack of such clause or
provision is, in the sole determination of Landlord, essential to the rights of
both parties in which event Landlord shall have the right to terminate this
Lease on written notice to Tenant.

         9.7 CAPTIONS. The captions used in this Lease are for convenience only
and do not in any way limit or amplify the terms and provisions hereof.

         9.8 SUCCESSORS AND ASSIGNS. The words "Landlord" and "Tenant" as used
herein shall include the respective contracting party, whether singular or
plural, and whether an individual, masculine or feminine, or a corporation,
general partnership, joint venture, limited partnership or trust. The provisions
of this Lease shall inure to the-benefit of and be binding upon Landlord and
Tenant, and their respective successors, heirs and assigns, subject, however, in
the case of Tenant, to the provisions of Section 2.5 hereof. It is understood
and agreed that the term "Landlord", as used in this Lease, means only the
owner(s), or the lessee(s), from time to time of the Building and/or the land
underlying the Building so that in the event of any sale or sales of the
Building and/or the land underlying the Building, or of any lease thereof, the
Landlord named herein shall be and hereby is

                                       45
<PAGE>

entirely freed and relieved of all covenants and obligations of Landlord
hereunder accruing thereafter to the extent of such sale or lease, and it shall
be deemed without further agreement that the purchaser, or the lessee, as the
case may be, has assumed and agreed, to the same extent, to carry out any and
all covenants and obligations of Landlord hereunder during the period such party
has possession of all or such portion of the Building and/or the land underlying
the Building which it has purchased or leased. Should all of the land underlying
the Building and the entire Building be severed as to ownership by sale and/or
lease, then, unless the Tenant is otherwise notified to the contrary in writing,
either the owner of the entire Building or the lessee of the entire Building, as
the case may be, which has the right to lease space in the Building to tenants
shall be deemed the "Landlord". Tenant shall be bound to any successor landlord
for all the terms, covenants, and conditions hereof and shall execute any
attornment agreement not in conflict herewith at the request of any successor
landlord.

         9.9 GEORGIA LAW. The laws of the State of Georgia shall govern the
interpretation, validity, performance and enforcement of this Lease.

         9.10 TIME IS OF THE ESSENCE. Time is of the essence of this Lease.
Unless specifically provided otherwise, all references to terms of days or
months shall be construed as references to calendar days or calendar months,
respectively.

         9.11 EXECUTION. This Lease may be executed in any number of
counterparts, each of which shall be deemed an original and any of which shall
be deemed to be complete in itself and may be introduced into evidence or used
for any purpose without the production of the other counterparts.

         9.12 FORCE MAJEURE. A party to this Lease shall be excused from the
performance of its duties and obligations under this Lease, except obligations
for the payment of money such as Base Rental, for the period of delay, but in no
event longer than ninety (90) days, caused by labor disputes, governmental
regulations, riots, war, insurrection, acts of God or other causes beyond the
control of the party whose performance is being excused (but such causes shall
not include insufficiency of funds).

         9.13 MULTIPLE TENANTS. Should more than one party enter into this
Lease as Tenant, each party so constituting Tenant shall be liable, jointly and
severally with the other or others, for all obligations of Tenant under this
Lease, and Landlord may enforce its rights hereunder against such party with or
without seeking enforcement thereof against the other or others.

         9.14 MUTUAL WARRANTY OF AUTHORITY. Landlord warrants to Tenant that
Landlord is a validly existing limited partnership under the laws of the State
of Georgia, that its entry into and performance of this Lease has been duly
authorized, and that the party executing this Lease on its behalf is duly
authorized to do so. Tenant, if other than an individual, warrants to Landlord
that Tenant is a validly existing legal entity under the

                                       46
<PAGE>

laws of the state of its formation and that it is duly qualified to do business
in the State of Georgia, that its entry into and performance of this Lease has
been duly authorized, and that the officer(s), partner(s) or trustee(s), as
applicable, executing this Lease on its behalf are duly authorized to do so.

         9.15 PARKING RIGHTS. For use by Tenant and its employees and invitees,
Landlord shall provide for Tenant's use seven days a week, 24 hours per day the
number of unassigned parking spaces as designated in the Lease Summary. Such
spaces shall be located in the on-site Parking Facility or in the parking
facility for 1365 Peachtree Road, a parking facility located on the property of
the First Presbyterian Church and, if necessary, such other location or
locations as is mutually acceptable to Landlord and Tenant, with Landlord and
Tenant hereby agreeing, that a location in the area described on EXHIBIT "H"
hereto or otherwise not more than a ten (10) minute shuttle ride from the
Building (if Landlord provides such a shuttle) is mutually acceptable, so long
as Tenant reasonably approves such location as being reasonably safe and secure,
with reasonable acceptable security assess and illumination. After acceptance of
such location, Landlord shall preserve the condition of such Parking Facility as
originally presented to Tenant for its approval. Any such off-site facilities so
provided shall be deemed a part of the "Parking Facility" for purposes of this
Lease, except where reference is made to the on-site parking Facility and
Landlord's obligation to provide spaces therein. Not less than the greater of
(x) 376 parking spaces, or (y) two (2) spaces per 1,000 square feet of Rentable
Area of the Premises will be located in the on-site Parking Facility (including,
without limitation, the facility for the 1365 Peachtree building) and shall be
available to Tenant during the Term of this Lease on a twenty-four (24) hour,
seven (7) days a week basis. Regardless of the location of the parking spaces
provided to Tenant, such parking spaces shall be provided to Tenant at the
prevailing market rate for such parking spaces, as said market rates shall be
determined and adjusted from time to time (except that the initial 376 parking
spaces provided in the on-site Parking Facility shall be $60.00 per space per
month during the Term) by Landlord or by the operator of such parking facility
at its sole discretion (the current market rate for spaces located in the
on-site Parking Facility is $60.00 per space per month). Tenant shall pay such
monthly charges to Landlord or to the operator of the Parking Facility on or
before the first (1st) day of each calendar month throughout the term of the
Lease, and Tenant shall abide by and comply with any and all regulations
promulgated by Landlord, the owner of the subject parking facility, or the
operator of the Parking Facility with respect to such parking spaces. All such
parking spaces attributable to any Phase of the Premises not rented at any time
after the Base Rental Commencement Date for such Phase may be rented or
otherwise disposed of by Landlord or the operator of the Parking Facility in the
ordinary course of their business without further obligation to Tenant with
respect thereto or any spaces in replacement thereof.

         9.16 NO RECORDATION OF LEASE. This Lease is not in recordable form,
and Tenant agrees not to record or permit the recording of this Lease.

         9.17 HAZARDOUS SUBSTANCES.

                  (a) Tenant hereby covenants that Tenant shall not cause or
         permit any "Hazardous Substances" (as hereinafter defined) to be
         placed, held, located or disposed of in, on or at the Premises or any
         part thereof and neither the Premises nor any part thereof shall ever
         be used as a dump site or storage site (whether permanent or temporary)
         for any Hazardous Substances during the Lease Term.

                  (b) Tenant hereby agrees to indemnify Landlord and hold
         Landlord harmless from and against any and all losses, liabilities,
         including strict liability, damages, injuries, expenses, including
         reasonable attorneys' fees, costs of any settlement or judgment and
         claims of any and every kind whatsoever paid, incurred or suffered by,
         or asserted against, Landlord by any person or entity or governmental
         agency for, with respect to, or as a direct or indirect result of the
         presence on or under, or the escape, seepage, leakage, spillage,
         discharge, emission, discharging or release from, the Premises of any
         Hazardous Substance (including, without limitation, any losses,
         liabilities, including strict liability, damages, injuries, expenses,
         including reasonable attorneys' fees, costs of any settlement or
         judgment or claims asserted or arising under the Comprehensive
         Environmental Response, Compensation and Liability Act, any so-called
         federal, state or local "Superfund" or "Superlien" laws, statute, law,
         ordinance, code, rule, regulation, order or decree regulating, relating
         to or imposing liability, including strict liability, substances or
         standards of conduct concerning any Hazardous Substance), provided,
         however, that the foregoing indemnity is limited to matters arising
         solely from Tenant's violation of the covenant contained in subsection
         (a) above.

                  (c) For purposes of this Lease, "Hazardous Substances" shall
         mean and include those elements or compounds which are contained in the
         list of hazardous substances now or hereafter adopted by the United
         States Environmental Protection Agency (the "EPA") or the list of toxic
         pollutants designated by Congress or the EPA or which are now or
         hereafter defined as hazardous, toxic, pollutant, infectious or
         radioactive by any other Federal, state or local statute, law,
         ordinance, code, rule, regulation, order or decree regulating, relating
         to, or imposing liability or standards of conduct concerning, any
         hazardous, toxic or dangerous waste, substance or material, as now or
         at any time hereafter in effect.

                  (d) Landlord shall have the right but not the obligation, and
         without limitation of Landlord's rights under this Lease, to enter onto
         the Premises or to take such other actions as it deems necessary or
         advisable to cleanup, remove, resolve or minimize the impact of, or
         otherwise deal with, any Hazardous Substance following receipt of any
         notice from any person or entity (including without limitation the EPA)
         asserting the existence of any Hazardous Substance in, on or at

                                       48
<PAGE>

         the Premises or any part thereof which, if true, could result in an
         order, suit or other action against Tenant or Landlord or both. All
         reasonable costs and expenses incurred by Landlord in the exercise of
         any such rights, which costs and expenses result from Tenant's
         violation of the covenant contained in subsection (a) above, shall be
         deemed additional rental under this Lease and shall be payable by
         Tenant upon demand.

                  (e) This Section 9.17 shall survive cancellation, termination
         or expiration of this Lease.

         9.18 NAMES. Upon written notice to Tenant, Landlord reserves the right,
from time to time, to change the name of the development, the name of the
Building and the street address of the Building, except that Landlord shall not
use the name of any tenant of the Building to identify the Building unless such
tenant occupies more space in the Building at the time the Building is so named
than does Tenant. Tenant shall not, without the prior written consent of
Landlord, use the name given the development, the Building, or any other
deceptively similar name, or use any associated service mark or logo of the
development or the Building for any purpose other than Tenant's business
address.

         9.19 SHARED COMMUNICATIONS SERVICES. Landlord may contract with a
vendor (the "Shared Services Vendor") to make available to tenants of the
Building certain shared communications services. With respect to such shared
communications services, if and so long as available, Landlord and Tenant agree
as follows:

                  (a) Tenant, at its election, may contract with Shared Services
         Vendor or any other vendor for communications services, including,
         without limitation, Southern Bell Telephone and Telegraph Company, the
         public utility provider of telecommunications regulated by the Georgia
         Public Service Commission. Tenant may make such election at its sole
         and absolute discretion.

                  (b) Tenant acknowledges and agrees that Shared Services Vendor
         is an independent contractor of Landlord and not Landlord's employee,
         agent, partner or joint venturer and Tenant waives any and all right
         Tenant may have or claim to have to assert the contrary.

                  (c) Tenant acknowledges and agrees that any cessation or
         interruption of shared communications services or default by Shared
         Services Vendor under the terms and conditions of Tenant's agreement
         with Shared Services Vendor shall not constitute a default under this
         Lease nor a constructive eviction by Landlord of Tenant. Tenant agrees
         that it shall not abate or setoff against any amount of Base Rental,
         Rental Adjustment, additional rent or other sum due under this Lease
         for any claim against Shared Services Vendor or for a default under
         Tenant's agreement with Shared Services Vendor. Tenant waives and
         releases Landlord from any and all claims Tenant may have, now or in
         the future, against

                                       49
<PAGE>

         Landlord, if any, that arise from or are related to the acts,
         omissions, negligence or gross negligence of Shared Services Vendor or
         its agents and employees.

         9.20 OWNERSHIP AND MANAGEMENT DISCLOSURE. Landlord discloses to Tenant,
and Tenant acknowledges, that Landlord is the owner of record of the Building
and the Premises and that Landlord's Broker, and its affiliates, are to manage
the Building and the Premises on behalf of Landlord. The address of Landlord's
Broker is 50 Glenlake Parkway, Suite 520, Atlanta, Georgia 30328. Landlord
shall provide Tenant with notice of any change in the management of the Building
at least thirty (30) days prior to any such change.

         9.21 EFFECT OF LEASE TERMINATION. No termination of this Lease by
reason of exercise of an optional right, lapse of time, failure of condition or
election of a party to terminate shall release or otherwise relieve either party
from liability for breach of this Lease or from performance of any contractual
obligation provided herein accruing prior to such termination. The possessory
rights of Tenant, however, shall cease and expire as of the effective time of
any such termination.

         9.22 SPECIAL STIPULATIONS. The Special Stipulations, if any, attached
hereto as EXHIBIT "E" and made a part hereof, are hereby incorporated herein and
in the event they conflict with any of the foregoing provisions, the Special
Stipulations shall control.

         WHEREAS, Tenant is the successor-in-interest to MEI and has acquired

the contrary, Tenant's obligation to pay rent on the First Amendment
Expansion Area shall be delayed by one day for each day that Tenant's
occupancy is delayed past November 14, 2000 due to Landlord's failure to
complete the Base Building Improvements including, without limitation,

         3. TENANT'S PERCENTAGE SHARE. Effective on the First Amendment
Expansion Date, the Lease Summary shall be amended to reflect that Tenant's

event that Tenant makes improvements, installs equipment, or takes any other
action (either with or without Landlord's consent) and such improvements,
equipment or actions preclude the use of any parking spaces for vehicular
parking, whether by blocking the parking space or reasonable access thereto,
then such unusable parking spaces shall be counted towards the total number of
unreserved spaces provided to Tenant under the Lease Summary and Section 9.15 as
if Tenant had the full use thereof.

         10. NO FURTHER AMENDMENTS; RATIFICATION. Except as expressly amended
herein, all terms and conditions of the Lease remain unamended and in full
force and effect and are hereby ratified and confirmed by Landlord and

and conditions of this First Amendment shall control.

                        SECOND AMENDMENT TO OFFICE LEASE

         THIS SECOND AMENDMENT TO OFFICE LEASE (hereinafter referred to as this
"Second Amendment") is effective as of this 21st day of December, 2000, by and
between KINGSTON ATLANTA PARTNERS, L.P., a Delaware limited partnership
(hereinafter referred to as "Landlord"), and EARTHLINK, INC., a Delaware
corporation (hereinafter referred to as "Tenant").

                              W I T N E S S E T H:

         WHEREAS, Landlord and Mindspring Enterprises, Inc., a Delaware
corporation (hereinafter referred to as "MEI") entered into that certain
Office Lease, dated November 16, 1999, as amended by the First Amendment to
Office Lease dated May 15, 2000 (hereinafter referred to as the "Lease"),
pursuant to which MEI leased from Landlord certain premises on the Terrace,
1st, 2nd, 3rd, 4th, 5th, 6th and 7th Floors of Pershing Point Plaza located
at 1375 Peachtree Road, N.E., Atlanta, Georgia 30309 (hereinafter referred to
as the "Building"), which premises are more particularly described in the
Lease (hereinafter referred to as the "Premises"); and

         WHEREAS, Tenant is the successor-in-interest to MEI and has acquired
all of MEI's right, title and interest in, to and under the Lease; and

         WHEREAS, Landlord and Tenant desire to amend the Lease to revise the
Lease Summary, and to provide for such other related matters as are hereinafter
set forth;

         NOW, THEREFORE, for and in consideration of the mutual covenants and
conditions set forth herein, and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, Landlord and Tenant
hereby agree as follows:

         1. DEFINED TERMS. Capitalized terms used herein, unless otherwise
defined herein, shall have the meanings given such terms in the Lease.

         2. LEASE SUMMARY. The Lease Summary, as attached to the Lease, is
hereby deleted and Exhibit B-1 attached hereto is hereby inserted in lieu
thereof. In the event of any conflict between the text of the Lease, as
amended by this Second Amendment, and the Lease Summary attached hereto as
Exhibit B-1, the Lease Summary shall control.

         3. LEASE OF SUNDRIES SHOP. Landlord hereby leases to Tenant and Tenant
hereby leases from Landlord those certain additional premises (the "Shop
Premises") located in the Building and commonly referred to as the "Sundries
Shop." The Shop Premises are more particularly described on the Site Plan
attached hereto as EXHIBIT A. The Shop Premises comprise 1,266 rentable square
feet. The rental to be paid by Tenant to Landlord for the Shop Premises shall be
the same AS the per rentable square foot "Base Rental" described in the Base
Rental section of the Lease Summary attached hereto (commencing with a rate of
$12.85 per

<PAGE>

square foot until 10/01/01, increasing to $13.24 on 10/02/01 and ending with a
rate of $15.35 on 10/01/07 all as more fully described in the Lease Summary and
based upon 1,266 rentable square feet). All other terms and conditions for
payment of rental as set forth in the Lease shall also apply to the payment of
rental for the Shop Premises including, without limitation, the provisions for
manner and time of payment, late payment and default. Tenant agrees that the
Shop Premises shall not be used for the operation of a delicatessen, restaurant
or other establishment that sells hot sandwiches and/or other hot meals. There
shall be no cooking by microwave, oven or otherwise in the Shop Premises. The
Shop Premises shall only be used for the operation of a sundries shop selling
items typically sold in sundries shops located in office buildings in the
Atlanta area including, by way of example, greeting cards, cold beverages,
pre-packages snacks, and health and beauty items such as over the counter
medications and hosiery. Tenant shall be permitted to sell Earthlink branded
apparel in the Shop Premises as well as related items such as accessories
bearing the Earthlink logo. Landlord shall have the right to approve the design
of any display at the Shop Premises that is visible from a public corridor or
other public area of the Building. Tenant shall not be permitted to sell any
name brand coffee at the Shop Premises but shall be permitted to sell generic
coffee. The Shop Premises may be open for business Monday through Friday from 7
am to 6 pm or such longer hours as may be agreed to by Landlord. All other
provisions of the Lease that are generally applicable to Tenant's original
leased premises shall also be applicable to the Shop Premises. No additional
parking shall be provided by Landlord to Tenant by virtue of the addition of the
Shop premises to the premises leased by Tenant from Landlord in the Building.

         4. UTILITIES. Effective as of December 1, 2000, the provisions of the
Lease with respect to utilities (which for purposes of this provision shall mean
electricity, gas, water and sewer) shall be modified as follows:

         (a) In order to accommodate Tenant's "around the clock" operations in
the Premises, Tenant shall have the right to utilize the Premises 24 hours per
day, 7 days per week, each day of each year throughout the Lease Term, subject
to the terms and conditions set forth herein. Landlord will continue to furnish
all of the services set forth in Section 5.2 of the Lease, but the timing
limitations on the services of electricity shall no longer be applicable. In
addition, the after hours or overtime charge for HVAC shall no longer be
applicable. In consideration of Landlord's agreement to furnish services on an
around the clock basis, Tenant will pay as Additional Rent the cost of all
utilities provided to the Premises in the manner set forth herein.

         (b) The cost of providing utilities to the Premises and the Building
shall still be considered part of Operating Expenses, but utilities will be
billed separately and calculated in accordance with the terms of this
provision. Landlord hereby represents and warrants that the Kinko's space
(containing approximately 5,965 rentable square feet and located in Suite 100
South Tower of the Building) is currently separately metered for all
utilities and will continue to be separately metered throughout the Lease
Term. Landlord further agrees that throughout the Lease Term, all other
tenant spaces in the Building (except the Premises) will be either separately
metered or submetered or utility consumption for such space will be measured
by means of engineering calculations. In order to ascertain utility
consumption based on engineering calculations, Landlord shall retain a
professional engineer with substantial experience in these matters to conduct
a survey of all tenant spaces (not otherwise separately metered or submetered
and excluding the Premises) and estimate consumption of all utilities for

                                       2
<PAGE>

each such space based on the density of occupancy, all equipment that operates
in the space, and any other relevant factors. In addition, Landlord shall
estimate the cost of providing utility services for the lighting on the parking
decks of the Building, the Atrium Lobby and the parking exhaust fans. Such items
shall be treated as normal Operating Expense and shall be prorated over the
entire Building for purposes of operating expenses escalations. From time to
time, if occupancy, equipment profiles or other relevant factors change
materially, the survey of the tenant spaces and resulting utility consumption
shall be updated.

         (c) Tenant will pay Landlord for all utilities consumed in the Building
except for (i) utilities consumed by Kinko's or any other tenants spaces
separately metered, (ii) utilities consumed by other tenants in the Building (as
measured by submetering or engineering calculation), and (iii) the common area
utility expenses set forth in Section 4(b) above, provided that Tenant shall pay
its Percentage Share of such expenses as part of Operating Expenses
(hereinafter, the "Net Utility Cost"). Notwithstanding the foregoing, all
utility accounts will still be maintained in Landlord's name, and Landlord will
still be responsible for payment of the utility bills from the various utility
providers. All utility charges will be billed to Tenant without additional
charge or markup of any kind.

         (d) Landlord's shall provide Tenant an initial estimate of the monthly
Net Utility Cost as soon as possible following execution of this Second
Amendment. Tenant shall pay to Landlord each month Landlord's estimate of the
monthly Net Utility Cost. Landlord shall have the right to adjust this estimate
from time to time, but not more than four (4) times per calendar year. Any
disagreements between Landlord and Tenant as to the appropriateness of
landlord's estimate shall be resolved by a qualified engineer. Each year when
Operating Expenses are reconciled pursuant to Section 3.3 of the Lease, the Net
Utility Cost shall also be reconciled in a similar manner. To this end, Landlord
shall provide Tenant with copies of all utility statements for the applicable
months, together with the information necessary to accurately determine the
appropriate utility charges to other tenants in the Building (based on separate
metering, submetering or engineering calculations, as applicable). Further,
Tenant shall have audit rights with respect to utilities generally in accordance
with the provisions of Section 3.3 of the Lease.

         (e) Understanding the additional wear and tear of equipment, Tenant
agrees to additional depreciation of equipment at $0.07/RSF to be passed through
to Tenant as a part of Building Operating Expenses each and every year of the
Lease.

         5. PARKING. Notwithstanding anything to the contrary contained in the
Lease including Section 9.15, Tenant agrees that from the date of this Second
Amendment forward, Landlord's only obligations to Tenant with respect to Tenant
parking and parking rights shall be as follows:

         (a) Landlord hereby confirms that the on-site Parking Facility contains
648 parking spaces, and Landlord agrees that at all times during the Lease Term
Landlord will maintain not less than 597 parking spaces in the on-site Parking
Facility.

         (b) Landlord shall provide for the exclusive use of Tenant, its
employees and invitees, (i) 502 parking spaces in the on-site Parking
Facility; and (ii) an additional 100 parking spaces located either in the
on-site Parking Facility or in the parking facility for 1365 Peachtree Road or

                                       3
<PAGE>

in a parking facility located on the property of the First Presbyterian Church,
or, if necessary, such other location or locations mutually acceptable to
Landlord and Tenant. Landlord and Tenant hereby agree that a location in the
area described on EXHIBIT "H" attached hereto or otherwise not more than a
10-minute shuttle ride from the Building (if Landlord provides such a shuttle)
is mutually acceptable so long as Tenant approves such location as being
reasonably safe and secure with reasonably acceptable security, access and
illumination. After selection of such location, Landlord shall preserve such
off-site parking facility in the same condition as originally presented to
Tenant for its approval, normal wear and tear excepted. Any such off-site
parking facility so provided shall be deemed a part of the "Parking Facility"
for purposes of this Lease, except where reference is made to the on-site
Parking Facility and Landlord's obligation to provide spaces therein. All
parking spaces shall be available to Tenant during the Lease Term on a 24 hour,
7 day per week basis (except for spaces used by congregants and invitees of the
First Presbyterian Church on Sundays).

         (c) The 502 parking spaces located in the on-site Parking Facility will
be located as shown in EXHIBIT "H-1" attached hereto. Such parking spaces shall
be for the exclusive use of Tenant, its employees and invitees, for the entire
Lease Term, and the location of such parking spaces may not be changed without
the prior written consent of both Landlord and Tenant. The exclusive parking
areas of Tenant will be clearly marked as such. Further, Landlord agrees to make
commercially reasonable efforts to prevent other parties from utilizing Tenant's
parking spaces.

         (d) Landlord may utilize the remaining parking spaces in the on-site
Parking Facility for parking by other tenants of the Building, their invitees
and employees, as well as third parties; provided, however, Landlord will
maintain not less than ten (10) visitors spaces in the on-site Parking Facility.
Such visitor spaces shall be located in the area shown on EXHIBIT "H-1" and will
be clearly marked as such.

         (e) The monthly parking rate for the initial 376 spaces provided to
Tenant in the on-site Parking Facility will be $60.00 per space per month during
the entire Lease Term. The monthly parking rate for the remaining 126 parking
spaces in the on-site Parking Facility and for the additional 100 parking spaces
(wherever located) shall be the prevailing market rate for such parking spaces,
as said market rate shall be determined and adjusted from time to time by
Landlord or by the operator of such parking facility in its reasonable
discretion. Tenant shall pay such monthly charges to Landlord or, if directed by
Landlord, to the operator of the applicable Parking Facility on or before the
first day of each calendar month throughout the Lease Term, and Tenant shall
abide and comply with any and all reasonable regulations promulgated by
Landlord, the owner of applicable Parking Facility with respect to such parking
spaces.

             Notwithstanding anything to the contrary contained herein,
Landlord acknowledges that Tenant will be charged on the number of parking
spaces rented by Tenant and not on the number of parking cards utilized by
Tenant.

         (f) Landlord shall manage the on-site Parking Facility, or shall cause
the Parking Facility to be managed, in a commercially reasonable manner
consistent with other parking facilities in the Midtown Atlanta area. Such
management will include providing parking attendants and valet parking during
the operating hours, 8am - 6pm, Monday through Friday,

                                       4
<PAGE>

cleaning and general maintenance of the Parking Facility and security services
in accordance with Section 5.2(g) of the Lease. If Tenant desires to have the
parking services extended beyond normal hours, Landlord and Tenant may enter
into a special services agreement for such additional services.

         (g) Tenant will administer the issuance and maintenance of parking
cards for its employees and will be responsible for tracking possession of
parking cards, the number issued, and vehicle identification information with
respect to its employees. Tenant shall receive 502 parking cards from the
Landlord or Landlord's designee at no cost. Tenant may obtain additional or
replacing cards from time to time and the cards are reimbursable to the Landlord
at the then prevailing market cost. In order to accommodate Tenant's multi-shift
operations, Tenant shall have the ability to issue multiple cards for each
parking space. Tenant shall be responsible for ensuring that Tenant's employees
park only in the parking spaces assigned to Tenant.

         6. NO FURTHER AMENDMENTS: RATIFICATION. Except as expressly amended
herein, all terms and conditions of the Lease remain in full force and effect
and are hereby ratified and confirmed by Landlord and Tenant. In the event of
any conflict between the terms and conditions of this Second Amendment and any
of the terms and conditions of the Lease, the terms and conditions of this
Second Amendment shall control.

         hereunder shall nevertheless continue in full force and effect.
         However, in such event Landlord and Tenant shall agree on an amendment
         of the original Lease Commencement Date to reflect such delay or delays
         and shall, in each instance, execute and attach hereto an amendment in
         the form of that attached as EXHIBIT F hereto stating such amended
         Lease Commencement Date and, if applicable, an amended Expiration Date
         and no rental shall be payable by Tenant hereunder until the amended
         Lease Commencement Date. The delay in commencement of the Term and in
         the accrual of rent described in the foregoing sentence shall
         constitute full settlement of

         all claims that Tenant might otherwise have by reason of the Premises
         not being ready for occupancy on the original Lease Commencement Date
         specified in Section I. above.

         If the Premises are not ready for occupancy by Tenant on the Lease
         Commencement Date due to one or more delays caused by Tenant, or anyone
         acting under or for Tenant, Landlord shall have no liability for such
         delay and the Lease Commencement Date shall nevertheless begin as of
         the Lease Commencement Date stated in Section I. (as extended only
         because of Landlord's delay pursuant to this subsection C., if
         applicable).

         (4)

D.       ACCEPTANCE AND SUITABILITY

         Within fifteen (15) days following the date Tenant takes possession
         of the Premises, Tenant may provide Landlord with a "punch list"
         which sets forth any itemization of any corrective work to be
         performed by Landlord with respect to the Landlord's Work as set
         forth in the Construction Work Letter; provided, however, that
         Tenant's obligation to pay Monthly Rental as provided below shall
         not be affected thereby. (5)If Tenant fails to submit such "punch
         list" to Landlord within such fifteen (15) day period, Tenant agrees
         that by taking possession of the Premises it will conclusively be
         deemed to have inspected the Premises and found the Premises in
         satisfactory condition. Tenant acknowledges that neither Landlord,
         nor any agent, employee or servant of Landlord, has made any
         representation with respect to the Premises or the Project, or with
         respect to the suitability of them for the conduct of Tenant's
         business, nor has Landlord agreed to undertake any modifications,
         alterations, or improvements of the Premises or Project, except as
         specifically provided in this Lease.

         TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, LANDLORD HEREBY
         DISCLAIMS, AND TENANT WAIVES THE BENEFIT OF, ANY AND ALL IMPLIED
         WARRANTIES, INCLUDING IMPLIED WARRANTIES OF HABITABILITY, FITNESS OR
         SUITABILITY FOR PURPOSE, OR THAT THE BUILDING OR THE IMPROVEMENTS IN
         THE PREMISES HAVE BEEN CONSTRUCTED IN A GOOD AND WORKMANLIKE MANNER.
         TENANT EXPRESSLY ACKNOWLEDGES THAT LANDLORD DID NOT CONSTRUCT OR
         APPROVE THE QUALITY OF CONSTRUCTION OF THE BUILDING.

[ILLEGIBLE]

Tenant's Initials

---------------------------
(4)      In the event that the Lease Commencement Date fails to occur within
         sixty (60) days of the Lease Commencement Date specified in Section I.
         above (which sixty (60) day period shall be extended one day for each
         day of delay caused by Tenant or force majeure (as defined in Section
         XXXIII.K. below)), then Tenant's obligation to pay Monthly Rental shall
         be delayed one day for each day after expiration of such sixty (60) day
         period (as so extended) and prior to the actual Lease Commencement
         Date. For example, if the Lease Commencement Date occurs May 1, 1997
         (a delay of seventy-six(76) days), solely as a result of Landlord
         delay, then Tenant's obligation to pay Monthly Rental shall commence
         May 17, 1997, notwithstanding the occurrence of the Lease Commencement
         Date.

(5)      Upon receipt of such punch-list, Landlord shall promptly commence to
         complete the items noted thereon which Landlord agrees are properly
         included on the punch-list, and will use reasonable efforts to complete
         such items within thirty (30) days of receipt of the punch-list.

         during the Term, rental for the entire Term in the total amount as set
         forth in EXHIBIT D payable in monthly installments (the "Monthly
         Rental") in the amount set forth in EXHIBIT D, which sum shall be
         payable by Tenant on or before the first day of each month, in advance,

         prior demand therefor and (7) without any abatement, deduction or
         setoff whatsoever. Monthly Rental for the first full month of the Term
         when rental is due shall be paid upon the execution hereof. If the
         Lease Commencement Date should occur on a day other than the first day
         of a calendar month, or the Expiration Date should occur on a day other
         than the last day of a calendar month, then the rental for such
         fractional month shall be prorated on a daily basis upon a thirty (30)
         day calendar month.

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

     (4) Notwithstanding the foregoing, Landlord will cure any latent defects
         in Landlord's Work which are not readily ascertainable upon a thorough
         walk-through of the Premises, which defects are identified by Tenant in
         a written notice given to Landlord within six (6) months of the Lease
         Commencement Date. Moreover, the provisions of this Section III.D.
         shall not abrogate Landlord's obligations pursuant to Section X.A.
         below.

         payment. Where no other time is stated herein for payment, payment of
         any amount payable from Tenant to Landlord hereunder shall be due,
         and made, within ten (10) days after Tenant's receipt of Landlord's
         invoice or statement therefor.

                  would have been paid or incurred by Landlord had the Building
                  been (12) rented and occupied and the amount so determined

                  such year.

B.       REIMBURSEMENT

         Within a reasonable time before the commencement of each calendar year
         during the Term, Landlord shall deliver to Tenant a reasonable estimate
         of the anticipated Common Operating Costs for the forthcoming calendar
         year. Tenant shall pay to Landlord, as additional rental, commencing on

         shall not be less than zero dollars($0). The estimated monthly charge

         of parking areas, painting buildings, refurbishing landscaping or
         walkways and similar items) during the year which was not included in
         determining the estimated Common Operating Costs, may be billed
         separately to Tenant according to Tenant's Proportionate Share.

C.   REBATE OR ADDITIONAL CHARGES

     Within a reasonable time after the end of each calendar year, Landlord
     shall furnish to Tenant a statement (each, an "Annual Statement") showing
     the total Common Operating Costs and Tenant's Proportionate Share of the
     Common Operating Costs less the Basic Operating Expense for the calendar
     year just ended. Tenant shall have the right, by written notice to Landlord
     given within(15) days after receipt of an Annual Statement, to
     protest specific items on the most recent Annual Statement; to be
     effective, Tenant's notice must state with specificity the item(s) to which
     Tenant objects. Tenant's failure to object to an Annual Statement as, when
     and in the manner provided in the preceding sentence shall render such
     Annual Statement binding on Tenant. If the amount of estimated Common
     Operating Costs less the Base Operating Expense paid by Tenant for any year
     during the Term exceeds the actual the Common Operating Costs less the Base
     Operating Expense for such year, Landlord shall apply any amounts due to
     Tenant hereunder to any outstanding amounts due or amounts next coming due
     from Tenant to Landlord. If the estimated Common Operating Costs less the
     Base Operating Expense for such year are less than the actual Common
     Operating Costs less the Base Operating Expense for such year, then Tenant
     shall pay to Landlord, within thirty (30) days of Tenant's receipt of the
     Annual Statement, as additional rent. Tenant's Proportionate Share of the
     difference between the amount of actual Common Operating Costs in excess of
     the Base Operating Expense and the amount of estimated Common Operating
     Costs in excess of Base Operating Expense. In the event the Term of this
     Lease expires, or this Lease is otherwise terminated. Landlord shall
     compute and prorate the credit or deficiency up to the date the Lease
     expired or was terminated and may apply any credit due Tenant to any
     outstanding amounts due by Tenant hereunder at that time and, at the end
     of the Lease, so long as Tenant is not then in default, shall (16)
     refund any excess to Tenant.

D.   CONTROL OF COMMON AREAS

     Landlord shall have the sole and exclusive control of the Common Areas, as
     well as the right to make changes to the Common Areas. Notwithstanding the
     preceding sentence, Landlord is not responsible for any harm or damage to
     any of Tenant's officers, agents, or employees as a result of their use of
     the Common Areas (17).  Landlord's rights shall include, but not be limited
     to, the right to (a) restrain the use of the Common Areas by unauthorized
     persons, (b) utilize from time to time any portion of the Common Areas for
     promotional and related matters, (c) temporarily close any portion of the
     Common Areas for repairs, improvements or alterations, (d) change the shape
     and size of the Common Areas or change the location of improvements within
     Common Areas, including, without limitation, parking areas, roadways and
     curb cuts, and (e) prohibit access to or use of Common Areas that are
     designated for the storage of supplies or operation of equipment necessary
     to operate the Project or Building. (18) Landlord may determine the

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

    16   promptly

    17   except subject to Sections XIV.C. and XV.b. below, if and to the
         extent it is determined by a court of competent jurisdiction the
         same were caused by Landlord's gross negligence or willful misconduct.

    18   ; provided, however, Landlord shall not exercise its rights pursuant
         to (b), (c) or (d) above so as to unreasonably interfere with
         Tenant's use and enjoyment of or access to the Premises

                                       8

     nature, size and extend of the Common Areas as well as make changes to the
     Common Areas from time to time which, in its (19) opinion, are deemed
     desirable.

SECTION VI. SECURITY DEPOSIT                        SEE ADDENDUM SECTION XXXV.D.

Upon execution of this Lease, Tenant shall deposit with Landlord the Security
Deposit defined in Section I. above, which shall be held by Landlord as
security for the performance by Tenant of all terms, covenants and conditions
of this Lease. It is expressly understood and agreed that such deposit is not
an advance rental deposit or a measure of Landlord's damage in case of
Tenant's default. If Tenant defaults with respect to any provision of this
Lease, including, but not limited to, the provisions relating to the payment
of rent or the obligation to repair and maintain the Premises or to perform
any other term, covenant or condition contained herein, Landlord may (but
shall not be required to), without prejudice to any other remedy provided
herein or provided by law and without notice to Tenant, use the Security
Deposit, or any portion of it, to cure the default or to compensate Landlord
for all damages sustained by Landlord resulting from Tenant's default. Tenant
shall immediately on demand pay to Landlord a sum equivalent to the portion
of the Security Deposit so expended or applied by Landlord as provided in
this paragraph so as to maintain the Security Deposit in the sum initially
deposited with Landlord. Although the Security Deposit shall be deemed the
property of Landlord, if Tenant is not in default at the expiration or
termination of this Lease, Landlord shall return the Security Deposit to
Tenant.  Landlord shall not be required to keep the Security Deposit separate
from its general funds and Landlord, not Tenant, shall be entitled to all
interests, if any, accruing on any such deposit. Upon any sale or transfer of
its interest in the Building, Landlord shall transfer the Security Deposit to
its successor in interest in the Building. Landlord shall transfer the
Security Deposit to its successor in interest and thereupon. Landlord shall
be released from any liability or obligation with respect thereto.

SECTION VII. TENANT'S TAXES

To the extent not covered as a Common Operation Cost, Tenant shall be liable for
any tax (now or hereafter imposed by any governmental entity) applicable to or
measured by or on the rents or any other charges payable by Tenant under this
Lease, including (but not limited to) any gross income tax, gross receipts tax
or excise tax with respect to the receipt of such rent or other charges or the
possession, leasing or operation, use or occupancy of the Premises, but not
including any net income, franchise, capital stock, estate or inheritance taxes.
If any such tax is required to be paid to the governmental taxing entity
directly by Landlord, then Landlord shall pay the amount due and, upon demand,
shall be fully reimbursed by Tenant for such payment.

Tenant shall also be liable for all taxes levied against leasehold held by
Tenant or against any personal property, leasehold improvements, additions,
alterations and fixtures placed by or for Tenant in, on or about the
Premises, Building and Project or constructed by Landlord (20) for Tenant in
the Premises; and if any such taxes are levied against Landlord or Landlord's
property, or if the assessed value of such property is increased (whether by
special assessment or otherwise) by the inclusion therein of value placed on
such leasehold, personal property, leasehold improvements, additions,
alterations and fixtures, and Landlord pays such any such taxes (which
Landlord shall have the right to do regardless of the validity thereof).
Tenant, upon demand, shall fully reimburse Landlord for the taxes so paid by
Landlord or for the proportion of such taxes resulting from such increase in
any assessment.

SECTION VIII. USE OF PREMISES

A.       PERMITTED USES

         Tenant shall use the Premises and Common Areas solely for the
         Permitted Use specified in subsection I.M. above, and for no other
         use, and under the name specified in subsection I.B. above. Tenant
         shall, at its own cost and expense, obtain any and all licenses and
         permits necessary for any such use. Tenant shall not do or permit
         anything to be done in or about the premises, Common Areas, Building
         or Project which will in any way (21) obstruct or interfere with the
         rights of other tenants or occupants of the Project or injure them
         or use or allow the Premises to be used for any unlawful purpose,
         nor shall Tenant cause, maintain or permit any nuisance in, on or
         about the Premises and Common Areas or permit any odors to emanate
         from the Premises and intrude upon the Common Areas or the premises
         of other tenants. Tenant shall not commit or suffer to be committed
         any waste in or upon the Premises, Common Areas, Building or
         Project. Tenant shall not do or permit anything to be done in or
         about the Premises, Common Areas, Building or Project which may
         render the insurance thereon void or increase the insurance risk
         thereon. If an increase in any fire and extended coverage insurance
         premiums paid by Landlord for the Building and Project is caused by
         Tenant's use and occupancy of the Premises, (22) then tenant shall
         pay as additional rental the amount of such increase to Landlord.

B.       COMPLIANCE WITH LAWS

         (23)

         Tenant shall not use the Premises, Building, Project, or Common
         Areas in any way (or permit or suffer anything to be done in or
         about the same) which will conflict with any law, statute, ordinance
         or governmental rule or regulation or any covenant, condition or
         restriction (whether or not of public record) affecting the
         Premises, Project or Building, now in force or which may hereafter
         be enacted or promulgated including, but not limited to, the
         provisions of any city or county zoning codes regulating the use
         thereof. Tenant shall, at its sole cost and expense, promptly comply
         with (a) all laws, statutes, ordinances and governmental rules and
         regulations, now in force or which may hereafter be in force,
         applicable to Tenant (24) its use of business or operations in the
         Premises, (b) all requirements, and other covenants, conditions and
         restrictions, now in force or which may hereafter be in force, which
         affect the Premises, and (c) all requirements, now in force or which
         may hereafter be in force, 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, Building
         or Project. The judgment of any court of competent jurisdiction or
         the admission by Tenant in any action against Tenant, whether
         Landlord be a party thereto or not, that Tenant has violated any
         law, statute, ordinance, governmental rule or regulation or any
         requirement, covenant, condition or restriction shall be conclusive
         of the fact as between Landlord and Tenant. Tenant agrees to fully
         indemnify Landlord against any liability, claims or damages arising
         as a result of a breach of the provisions of this subsection by
         Tenant, and against

_______________________________

(21)   , in Landlord's reasonable opinion,

(22)   as evidenced by a letter from the insurance company,

(23)   If and to the extent that Landlord's Work or the Common Areas are not in
       compliance with applicable governmental requirements as in effect and as
       applied to the Building as of the Lease Commencement Date, Landlord
       shall, if, as and when required by such applicable governmental
       authorities, cause Landlord's Work or the Common Areas, as applicable, to
       comply therewith.

(24)   relating to

                                       10
<PAGE>

         all costs, expenses, fines or other charges arising therefrom,
         including, without limitation, reasonable attorneys' fees and related
         costs incurred by Landlord in connection therewith, which indemnity
         shall survive the expiration or earlier termination of this Lease.
         Without limiting the generality of the foregoing, it is expressly
         understood and agreed that, subject to (25) performance by Landlord of
         Landlord's Work described in EXHIBIT C hereto. Tenant is accepting the
         Premises "AS IS," in its present state and condition, without any
         representations or warranties from Landlord of any kind whatsoever,
         either express or implied, with respect to the Premises or the
         Building, including without limitation the compliance of the Premises
         or the Building with The Americans With Disabilities Act and the rules
         and regulations promulgated thereunder, as amended from time to time
         (the "ADA").(26) Except as otherwise provided for in EXHIBIT C hereto,
         if Tenant's use of the Premises or operations therein cause Landlord
         to incur any obligation under the ADA, as reasonably determined by
         Landlord, then Tenant shall reimburse Landlord for Landlord's costs and
         expenses in connection therewith. If Tenant's initial use of the
         Premises is not a "place of public accommodation" within the meaning of
         the ADA, then Tenant may not thereafter change the use of the Premises
         to cause the Premises to become a "place of public accommodation." In
         the event that Tenant desires or is required hereby to make Alterations
         (as defined below) to the Premises in order to satisfy its obligations
         under the ADA, then all such Alterations shall be subject to any
         requirements in the Lease with respect to Alterations of the Premises,
         and shall be performed at Tenant's sole cost and expense. Except for
         Alterations to the Premises, Tenant shall have no right whatsoever to
         make any alterations or modifications to any portion of the Building or
         its appurtenant facilities. Tenant shall be responsible for insuring
         that the Premises and Tenant's use thereof and operations therein fully
         and completely comply with the ADA.

C.       HAZARDOUS MATERIALS                        See Addendum Section XXXV.E.

         Tenant covenants and agrees that it shall not cause or permit any
         Hazardous Material (as defined below) to be brought upon, kept, or
         used in or about the Premises, Building or Project by Tenant, its
         agents, employees, contractors or invitees. The foregoing covenant
         shall not extend to substances typically used in general office
         applications so long as (i) such substances and any equipment which
         generates such substances are maintained only in such quantities as
         are reasonably necessary for Tenant's operations in the Premises,
         (ii) such substances are used strictly in accordance with the
         manufacturers' instructions therefor, (iii) such substances are not
         disposed of in or about the Project in a manner which would
         constitute a release or discharge thereof, and (iv) all such
         substances and any equipment which generates such substances are
         removed from the Project by Tenant upon the expiration or earlier
         termination of this Lease. Any use, storage, generation, disposal,
         release or discharge by Tenant of Hazardous Materials in or about
         the Project as is permitted pursuant to this subsection C, shall be
         carried out in compliance with all applicable federal, state and
         local laws, ordinances, rules and regulations. Moreover, no
         hazardous waste resulting from any operations by Tenant shall be
         stored or maintained by Tenant in or about the Project for more than
         ninety (90) days prior to removal by Tenant. Tenant shall, annually
         within thirty (30) days after Tenant's receipt of Landlord's written
         request therefor, provide to Landlord a written list identifying any
         Hazardous Materials then maintained by Tenant in the Project, the use
         of each such Hazardous Material and the approximate quantity
         of each such Hazardous Material so maintained by Tenant, together with
         written certification by Tenant stating, in substance, that neither
         Tenant nor any person for whom Tenant is responsible has released or
         discharged any Hazardous Materials in or about the Project.

______________________________

(25)   footnote 23 above and to

(26)   Notwithstanding the foregoing, but subject to the three immediately
       succeeding sentences of this subsection B., Landlord shall be
       responsible, at Landlord's sole cost and expense, for compliance of the
       Common Areas with the ADA.

                                       11

         In the event that Tenant proposes to conduct any use or to operate
         any equipment which will or may utilize or generate a Hazardous
         Material other than as specified in the first paragraph of this
         subsection, Tenant shall first in writing submit such use or
         equipment to Landlord for approval. No approval by Landlord shall
         relieve Tenant of any obligation of Tenant pursuant to this
         subsection, including the removal, clean-up and indemnification
         obligations imposed upon Tenant by this subsection. Tenant shall,
         within five (5) days after receipt thereof, furnish to Landlord
         copies of all notices or other communications received by Tenant
         with respect to any actual or alleged release or discharge of any
         Hazardous Material in or about the Premises or the Project and
         shall, whether or not Tenant receives any such notice or
         communication, notify Landlord in writing of any discharge or
         release of Hazardous Material by Tenant or anyone for whom Tenant is
         responsible in or about the Premises or the Project. In the event
         that Tenant is required to maintain any Hazardous Materials license
         or permit in connection with any use conducted by Tenant or any
         equipment operated by Tenant in the Premises, copies of each such
         license or permit, each renewal or revocation thereof and any
         communication relating to suspension, renewal or revocation thereof
         shall be furnished to Landlord within five (5) days after receipt
         thereof by Tenant. Compliance by Tenant with the two immediately
         preceding sentences shall not relieve Tenant of any other obligation
         of Tenant pursuant to this subsection.

         Upon any violation of the foregoing covenants, Tenant shall be
         obligated, at Tenant's sole cost, to clean-up and remove from the
         Project all Hazardous Materials introduced into the Project by Tenant
         or any person or entity for whom Tenant is responsible. Such clean-up
         and removal shall include all testing and investigation required by any
         governmental authorities having jurisdiction and preparation and
         implementation of any remedial action plan required by any governmental
         authorities having jurisdiction. All such clean-up and removal
         activities of Tenant shall, in each instance, be conducted to the
         satisfaction of Landlord and all governmental authorities having
         jurisdiction. Landlord's right of entry pursuant to Section XI. shall
         include the right to enter and inspect the Premises for violations of
         Tenant's covenants herein.

         Tenant shall indemnify, defend and hold harmless Landlord, its
         partners, and its and their successors, assigns, partners, officers,
         employees, agents, lenders and attorneys from and against any and all
         claims, liabilities, losses, actions, costs and expenses (including
         attorneys' fees and costs of defense) incurred by such indemnified
         persons, or any of them, as the result of (A) the introduction into or
         about the Project by Tenant or anyone for whom Tenant is responsible of
         any Hazardous Materials, (B) the usage, storage, maintenance,
         generation, disposition or disposal by Tenant or anyone for whom Tenant
         is responsible of Hazardous Materials in or about the Project, (C) the
         discharge or release in or about the Project by Tenant or anyone for
         whom Tenant is responsible of any Hazardous Materials, (D) any injury
         to or death of persons or damage to or destruction of property
         resulting from the use, introduction, maintenance, storage, generation,
         disposal, disposition, release or discharge by Tenant or anyone for
         whom Tenant is responsible of Hazardous Materials in or about the
         Project, and (E) any failure of Tenant or anyone for whom Tenant is
         responsible to observe the foregoing covenants of this subsection.

         Upon any violation of the foregoing covenants, Landlord shall be
         entitled to exercise all remedies available to a landlord against a
         defaulting tenant, including but not limited to those set forth in
         Section XX. Without limiting the generality of the foregoing, Tenant
         expressly agrees that Landlord may, at its option, (I) (27) immediately
         terminate this Lease or (II) (28) continue this Lease in effect until

______________________________

(27)   which is not cured within the applicable cure period and, at Landlord's
       sole option, upon the third or subsequent violation of any one or more of
       the foregoing covenants (regardless of whether any prior violations were
       cured within any applicable cure period),

(28)   upon any such violation,

         compliance by Tenant with its clean-up and removal covenant
         notwithstanding any earlier expiration date of the term of this Lease.

         pursuant to this subsection.

                                                      Sections XXXV.C.(2) and F.

   So long as Tenant is not in default hereunder (of a type described in clauses
   (4) - (6) of Section XX.A. below), Landlord agrees to make available to the
   Premises, during the Building's normal business hours of 7:00 a.m. to 6:00
   p.m. Monday through Friday and 8:00 a.m. to 12:00 p.m. on Saturday (holidays
   excepted), which hours are subject to change from time to time as reasonably

   the area where the Project is located, all of which shall be subject to the
   Rules of the Building as well as any governmental requirements or standards
   relating to, among other things, energy conservation. Tenant agrees to pay,
   as a Common Operating Cost in accordance with Section V. above, Tenant's
   Proportionate Share in excess of the Base Operating Expense of the full cost
   of all utilities supplied to the Premises, together with any taxes thereon,
   (33) any such service or utilities (34) are separately metered to the
   Premises, Tenant shall pay the cost thereof in a timely manner directly to
   the utility company providing such service. Tenant's obligations in this
   Section regarding utilities include, but are not limited to, all charges for
   gas, water and electricity used on the Premises, and for all electric light
   lamps or tubes. If any such utility or service is not separately metered to
   the Premises, Tenant shall be required to pay any increased cost, as

   services as reasonably determined by Landlord or any unusual or non-customary
   use beyond that which Landlord has agreed to make available as described
   above, or resulting from special electrical, cooling and ventilating needs
   created in certain areas by telephone equipment, computers and other similar
   equipment or uses. If the Building is designed for individual tenant
   operation of the HVAC, Tenant agrees to pay the cost of operating the HVAC at
   any time other than the schedule of hours for providing the same set forth
   above, which cost may include the operation of the HVAC for space located
   outside the Premises when such space is serviced concurrently with the
   operation of the HVAC for the benefit of the Premises.

B. LIMITATION ON LANDLORD'S OBLIGATIONS

   Landlord shall not be in breach of its obligations under this Section unless
   Landlord fails to make any repairs or perform maintenance which it is
   obligated to perform hereunder and such failure persists for an unreasonable
   time after written notice of a need for such repairs or maintenance is given
   to Landlord by Tenant. Landlord shall not be liable for and Tenant shall not
   be entitled to any abatement or reduction of rent by reason of Landlord's
   failure to furnish any of the foregoing when such failure is caused by
   accidents, breakage, repairs, strikes, brownouts, blackouts, lockouts or
   other labor disturbances or labor disputes of any character, or by any other
   cause, similar or dissimilar, beyond the reasonable control of Landlord, nor
   shall such failure under such circumstances be construed as a constructive or
   actual eviction of Tenant. (35) Landlord shall not be liable under any
   circumstances for loss or injury to property or business, however occurring,
   through or in connection with or incidental to Landlord's failure to furnish
   any of said service or utilities.

C. EXCESS SERVICE

   Tenant shall not, without the written consent of Landlord, use any apparatus
   or device in the Premises, including, without limitation, electronic data
   processing machines, punch card machines or machines using in excess of one
   hundred twenty (120) volts or which consumes more electricity than is usually
   furnished or supplied for the  Permitted Use of the Premises, as determined
   by Landlord. Tenant shall not consume water or electric current in excess of
   that usually furnished or supplied for the use of the Premises (as determined
   by Landlord), without first procuring the written consent of Landlord, which
   Landlord may refuse. The excess cost (including any penalties for excess
   usage) for such water and electric current shall be established by an
   estimate made by a utility company or independent engineer hired by Landlord
   at Tenant's expense and Tenant shall pay such excess costs each month with
   the Monthly Rental. All costs and expenses of modifying existing equipment,
   cables,  lines, etc. or installing additional equipment, cables, lines, etc.
   to accommodate such excess usage or use by Tenant of such apparatus or device
   shall be borne by Tenant.

--------------
     (35)  If, as a result of Landlord's negligence or willful misconduct,
           utility service to the Premises is interrupted and continues
           interrupted for a period of in excess of three (3) consecutive
           business days after written notice thereof is given to Landlord by
           Tenant (which three (3) business day period shall be extended by
           force majeure events described in Section XXXIII.K below) and which
           interruption materially prohibits the use of the Premises for the
           Permitted Use, then Monthly Rental and Tenant's obligation to pay
           Common Operating Costs shall abate from and after expiration of such
           three (3) business day period (as so extended) until service is
           restored (regardless of whether it is later interrupted) if and to
           the extent that Tenant's ability to conduct business within the
           Premises is materially and adversely affected by the interruption.

D. SECURITY SERVICES

   Certain security measures (both by electronic equipment and personnel) may be
   provided by Landlord in connection with the Building and Common Areas.
   However, Tenant hereby acknowledges that such security is intended to be only
   for the benefit of the Landlord in protecting its property from fire, theft,
   vandalism and similar perils and while certain incidental benefits may accrue
   to the Tenant therefrom, such security is not for the purpose of protecting
   either the property of Tenant or the safety of its officers, employees,
   servants or invitees. By providing such security, Landlord assumes no
   obligation to Tenant and shall have no liability arising therefrom. If, as a
   result of Tenant's occupancy of the Premises, Landlord in its (36) discretion
   determines that it is necessary to provide security or implement additional
   security measures or devices in or about the Building or the Common Areas,
   Tenant shall be required to pay, as additional rent, the cost or increased
   cost, as the case may be, of such security.

   intentional act or omission of Tenant or any person claiming through or under
   Tenant or any of Tenant's employees, suppliers, shippers, customers or
   invitees, in which event Tenant shall repair such damage at its sole cost and
   expense. Tenant hereby waives and releases its right to make repairs at
   Landlord's expense under any law, statute, ordinance, rules and regulations
   now or hereafter in effect in any jurisdiction in which the Project is
   located.

obtain Landlord's preliminary consent, which preliminary consent may be given
or denied(53) in Landlord's sole discretion.(54) Tenant shall submit such
information as Landlord may require, including without limitation plans and
specifications for the Alterations. Any professional fees or other costs and
expenses incurred by Landlord in reviewing such plans and specifications
shall be paid to Landlord by Tenant as additional rent upon demand. After

writing, immediately become the property of Landlord, without compensation to
Tenant, but Landlord has no obligation to repair, maintain or insure those
Alterations. Carpeting, shelving and cabinetry are considered improvements of
the Premises and not moveable trade fixtures, regardless of how or where
affixed. No Alterations will be removed by Tenant from the Premises either

Landlord free and harmless from and against all liability, loss, damage,
cost, attorney's fees and any other expense incurred on account of claims by
any person performing work or furnishing materials or supplies for Tenant or
any person claiming under Tenant. Landlord may require Tenant to provide
Landlord, at Tenant's sole cost and expense, a lien and completion bond in an
amount equal to one and one-half times the estimated cost of such
improvements, to insure Landlord against any liability for mechanic's liens
and to insure completion of the work. Landlord shall have the right at all
times to post on the Premises any notices permitted or required by law, or
that Landlord shall deem proper, for the protections of Landlord, the
Premises, the Building and the Project, and any other party having an
interest therein, from

         in the aggregate, over a twelve (12) month period in excess of

or for Tenant or any person or entity claiming through or under Tenant. In the
event that Tenant shall not, within fifteen (15) days following the imposition
of any such lien, cause the same to be released of record by payment or passing
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 such
lien to be released by such means as Landlord deems proper, including payment of
the claim giving rise to such lien. All such sums paid and all expenses incurred

    maintain the level of insurance protection at least equal to the protection

    secure the insurance coverage required under this Section XIV., then
    Landlord shall have, in addition to all other remedies provided herein and
    by law, the right, but not the obligation, to procure and maintain such
    insurance, the cost of which shall be due and payable to Landlord by Tenant
    on demand.

    any other policy of property insurance carried by such waiving party in lieu
    thereof) at the time of such loss or damage. The foregoing waiver shall be
    effective whether or not a waiving party actually obtains and maintains such
    insurance which such waiving party is required to obtain and maintain

      of this Section, Tenant is deemed a co-insurer by its insurance
      carrier, then any loss or damage which Tenant shall sustain by reason
      thereof shall be borne by Landlord and shall be immediately paid by
      Landlord upon receipt of a bill therefor and evidence of such loss.

 (62) (herein "Claims")

 (63) Notwithstanding the foregoing, if and to the extent that a court of
      competent jurisdiction determines that a Claim was caused by the gross

      by Tenant in defending Landlord in connection with such Claim.

     the satisfaction of any such claim, judgment, injunction or decree.
     Moreover, Tenant agrees that Landlord shall in no event and under no
     circumstances be responsible for any consequential damages incurred or
     sustained by Tenant, or its employees, agents, contractors or invitees as a
     result of or in any way connected to Tenant's occupancy of the Premises.

     damage to any property or person occasioned by theft, fire, act of God,
     public enemy, injunction, riot, strike, insurrection, war, court order,
     requisition, or order of governmental body or authority, or for any damage
     or inconvenience that may arise through repair or alteration of any part of

     relevant to such decision, including but not necessarily limited to the
     following, all of which are agreed to be reasonable factors for Landlord's
     consideration:

     (1)  The financial strength of the proposed assignee or subtenant (which
          shall be at least equal to that of Tenant as of the date of execution
          of this Lease).

     (2)  The experience of the proposed assignee or subtenant with respect to
          businesses of the type and size which such assignee or subtenant
          proposes to conduct in the Premises.

     (3)  The quality and nature of the business and/or services to be conducted
          in or from the Premises by the proposed assignee or subtenant and in
          any other locations which it has.

     (4)  Violation of exclusive use rights previously granted by Landlord to
          other tenants of the Building or Project.

     (5)  The effect of the type of services and business which the proposed
          assignee or subtenant proposes to conduct in the Premises upon the
          tenant mix in the Building or in the portion of the Project which
          contains the Premises, including duplication of services offered by
          surrounding tenants and compatibility of the services and business
          which such assignee or subtenant proposes to conduct in or offer from
          the Premises with business and services conducted by surrounding
          tenants in the Project.

(66) Tenant shall also provide to Landlord the foregoing information at the time
     Tenant notifies Landlord of any Assignment or Sublease for which Landlord's
     consent is not required hereunder.

     (8)  Whether the business in the Premises is, and whether the business to
          be operated by the proposed assignee or subtenant will be, a(68)

     (9)  Whether there then exists any default by Tenant pursuant to this Lease
          or any non-payment or non-performance by Tenant under this Lease
          which, with the passage of time and/or the giving of notice, would
          constitute a default under this Lease.

     (10) Any fact or factor upon which Landlord reasonably concludes that the
          business to be conducted by such assignee or subtenant will not be a
          financial success in the Premises.

     Moreover, Landlord shall be entitled to be reasonably satisfied that each
     and every covenant, condition or obligation imposed upon Tenant by this
     Lease and each and every right, remedy or benefit afforded Landlord by this
     Lease is not impaired or diminished by such Assignment or Sublease. In no
     event shall there be any substantial change in the use of the Premises in
     connection with any Assignment or Sublease except as expressly approved in
     writing by Landlord in advance. Landlord and Tenant acknowledge that the
     express standards and provisions set forth in this Lease dealing with
     Assignment and Sublease, including those set forth in subsections XVI.D.,
     E. and G. have been freely negotiated and are reasonable at the date hereof
     taking into account Tenant's proposed use of the Premises and the nature of
     the Building and Project. No withholding of consent by Landlord for any
     reason deemed sufficient by Landlord shall give rise to any claim by Tenant
     or any proposed assignee or subtenant or entitle Tenant to terminate this
     Lease or to any abatement of rent. Approval of any Assignment of Tenant's
     interest shall, whether or not expressly so stated, be conditioned upon
     such assignee assuming in writing all obligations of Tenant hereunder by a
     written instrument satisfactory to Landlord.

D.   If Landlord consents to the Sublease or Assignment within said thirty (30)
     day period, Tenant may enter into such Assignment or Sublease of the
     Premises or portion thereof, but only upon the terms and conditions set
     forth in the notice furnished by Tenant to Landlord pursuant to subsection
     B. above; provided, however, that in connections with(69) such Assignment
     or Sublease(70), as a condition to Landlord's consent, Tenant shall pay to
     Landlord one hundred percent (100%) of the excess, if any, of (i) in the
     case of an Assignment, the rental and other payment obligations of the
     proposed assignee under the terms of the proposed Assignment over (71) the
     rental and other payment obligations of Tenant under the terms of this
     Lease(72), or (ii) in the case of a Sublease, the amount proposed to be
     paid by the sublessee over (73) the proportionate amount of rental and
     other

     in Tenant's Work and which are usable and used by the assignee and
     brokers' commissions, advertising costs and costs of tenant improvements
     required to be paid or performed by Tenant as a condition to or in
     connection with such Assignment

   payment obligations required to be paid by Tenant to Landlord under the terms
   of this Lease (74) as applicable to the portion of the Premises so subleased.

E. No consent by Landlord to any Assignment or Sublease by Tenant shall
   relieve Tenant of any obligation to be performed by Tenant under this Lease,
   whether arising before or after the Assignment or Sublease. The consent by
   Landlord to any Assignment or Sublease shall not relieve Tenant of the
   obligation to obtain Landlord's express written consent to any other
   Assignment or Sublease. Any Assignment or Sublease that is not in compliance
   with this Section shall be void and, at the option of Landlord, shall
   constitute a material default by Tenant under this Lease. The acceptance of
   rent by Landlord or payment to Landlord of any other monetary obligation by a
   proposed assignee or sublessee shall not constitute the consent by Landlord
   to such Assignment or Sublease. Tenant shall promptly provide to Landlord a
   copy of the fully executed Sublease or Assignment.

F. Any sale or other transfer, including transfer by consolidation, merger
   or reorganization, of twenty-five percent (25%) or more of the voting stock
   of Tenant, if Tenant is a corporation, or any sale or other transfer of
   twenty-five percent (25%) or more of the partnership interest in Tenant, if
   Tenant is a partnership, shall be an Assignment for purposes of this Section.
   As used in this subsection, the term "Tenant" shall also mean any entity that
   has guaranteed Tenant's obligation under this Lease, and the prohibition
   hereof shall be applicable to any sales or transfers of stock or partnership
   interests of said guarantor.

G. Each assignee, sublessee or other transferee, other than Landlord, shall
   assume, as provided in this subsection all obligations of Tenant under this
   Lease and shall be and remain liable jointly and severally with Tenant for
   the payment of Monthly Rental and all other monetary obligations hereunder,
   and for the performance of all the terms, covenants, conditions and
   agreements herein contained on Tenant's part to be performed for the Term;
   provided, however, that the assignee, sublessee, or other transferee shall be
   liable to Landlord for rent only in the amount set forth in the Assignment or
   Sublease. No Assignment shall be binding on Landlord unless the assignee or
   Tenant shall deliver to Landlord a counterpart of the Assignment and an
   instrument in recordable form that contains a covenant of assumption by the
   assignee satisfactory in substance and form to Landlord, consistent with the
   requirements of this subsection but the failure or refusal of the assignee to
   execute such instrument of assumption shall not release or discharge the
   assignee from its liability as set forth above.

H. If this Lease is assigned to any person or entity pursuant to the
   provisions of the Bankruptcy Code, 11 U.S.C. Section 101 ET SEQ., (the
   "Bankruptcy Code"), any and all monies or other consideration payable or
   otherwise to be delivered in connection with such assignment shall be paid
   or delivered to Landlord, shall be and remain the exclusive property of
   Landlord and shall not constitute property of Tenant or of the estate of
   Tenant within the meaning of the Bankruptcy Code. Any and all monies or other
   considerations constituting Landlord's property under the preceding sentence
   not paid or delivered to Landlord shall be held in trust for the benefit of
   Landlord and be promptly paid or delivered to Landlord.

I. Any person or entity to which this Lease is assigned pursuant to the
   provisions of the Bankruptcy Code, shall be deemed, without further act or
   deed, to have assumed all of the obligations arising under this Lease on and
   after the date of such assignment. Any

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

(74)      plus (2) the unamortized costs of improvements incurred and paid for
          by Tenant (I.E., not covered by the Tenant Allowance) which are
          included in Tenant's Work and which are usable and used by the
          subtenant and brokers' commissions, advertising costs and costs of
          tenant improvements required to be paid or performed by Tenant as a
          condition to or in connection with such Sublease, spread evenly over
          the term of the Sublease and deducted from the sublessee's rentals so
          amortized, in each case

                                       26

<PAGE>

   such assignee shall upon demand execute and deliver to Landlord an
   instrument confirming such assumption.

J. Tenant shall pay Landlord's expenses and (75) attorneys' fees
   incurred in processing an Assignment or Sublease, but in no event less than
   Five Hundred Dollars ($500.00) for each such proposed transfer to cover
   the legal review and processing expenses of Landlord, whether or not Landlord
   shall grant its consent to such proposed transfers.

K. All options to extend, renew or expand, if any, contained in this Lease are
   personal to Tenant (76). Consent by Landlord to any Assignment or
   Subletting shall not include consent to the assignment or transfer of any
   such rights with respect to the Premises or any special privileges or extra
   services granted to Tenant by this Lease, or any addendum or amendment
   hereto or letter of agreement. All such options, rights, privileges and extra
   services shall terminate upon such assignment or subletting unless Landlord
   specifically grants in writing such options, rights, privileges and extra
   services to such assignee or subtenant.

SECTION XVII. TRANSFER OF LANDLORD'S INTEREST

In the event Landlord shall sell or otherwise convey its title to the
Building, then, after the effective date of such sale or conveyance, Landlord
shall have no further liability under this Lease to Tenant except as to
matters of liability which have accrued and are unsatisfied as of the date of
sale or conveyance, and Tenant shall seek performance solely from Landlord's
purchaser or successor in title. In connection with such sale or transfer,
Landlord may assign its interest under this Lease without notice to or
consent by Tenant. In such event, Tenant agrees to be bound to any successor
Landlord.

SECTION XVIII. DAMAGE AND DESTRUCTION

A. MINOR INSURED DAMAGE

   In the event the Premises or the Building, or any portion thereof, is damaged
   or destroyed by any casualty that is covered by the insurance maintained by
   Landlord pursuant to Section XIV, above, then Landlord shall rebuild, repair
   and restore the damaged portion thereof, provided that (1) the amount of
   insurance proceeds available to Landlord equals or exceeds the cost of such
   rebuilding, restoration and repair, (2) such rebuilding, restoration and
   repair can be completed within one hundred eighty (180) days after the work
   commences in the (77) opinion of a registered architect or engineer
   appointed by Landlord, (3) the damage or destruction has occurred more than
   twelve (12) months before the expiration of the Term, and (4) such
   rebuilding, restoration or repair is then permitted, under applicable
   governmental laws, rules and regulations, to be done in such a manner as to
   return the damaged portion thereof to substantially its condition immediately
   prior to the damage or destruction, including, without limitation, the same
   net rentable floor area. To the extent that insurance proceeds must be paid
   to a mortgagee or beneficiary under, or must be applied to reduce any
   indebtedness secured

   the condemnation or taking, this Lease shall automatically terminate as of
   the earlier of the date on which actual physical possession is taken by the
   condemnor or the date of dispossession of Tenant as a result of such
   condemnation or other taking. If less than all or substantially all of the
   Premises is so condemned or taken, this Lease shall automatically terminate
   only as to the portion of the Premises so taken as of the earlier of the date
   on which actual physical possession is taken by the condemnor or the date of
   dispossession of Tenant as a result of such condemnation or taking (79). If
   such portion of the Building is condemned or otherwise taken so as to
   require, in the opinion of Landlord, a substantial alteration or
   reconstruction of the remaining portions thereof, this Lease may be
   terminated by Landlord, as of the date on which actual physical possession is
   taken by the condemnor or dispossession of Tenant as a result of such
   condemnation or taking, by written notice to Tenant within sixty (60) days
   following notice to Landlord of the date on which such physical possession is
   taken or dispossession will occur.

B. AWARD

   Landlord shall be entitled to the entire award if any condemnation
   proceeding or other proceeding for taking for public or quasi-public use,
   including, without limitation, any award made for the value of the leasehold
   estate created by this Lease. No award for any partial or total taking shall
   be apportioned, and Tenant hereby assigns to Landlord any award that may be
   made in such condemnation or other taking, together with any and all rights
   of Tenant now or hereafter arising in or to the same or any part thereof.
   Although all damages in the event of any condemnation are to belong to
   Landlord whether such damages are awarded as compensation for diminution in
   value of the leasehold or to the fee of the Premises. Tenant shall have the
   right to claim and recover from the condemnor, but not from Landlord, such
   compensation as may be separately awarded or recoverable by Tenant in
   Tenant's own right on account of damages to Tenant's business by reason of
   the condemnation and for or on account of any cost or loss to which Tenant
   might be put in removing Tenant's merchandise, furniture and other personal
   property, fixtures, and equipment or for the interruption of or damage to
   Tenant's business.

C. ABATEMENT IN RENT

   In the event of a partial condemnation or other taking that does not
   result in a termination of this Lease as to the entire Premises pursuant to
   this Section the rent and all other charges shall abate in proportion to the
   portion of the Premises taken by such condemnation or other taking. If this
   Lease is terminated, in whole or in part, pursuant to any of the provisions
   of this Section all rentals and other charges payable by Tenant to Landlord
   hereunder and attributable to the Premises taken shall be paid up to the date
   upon which actual physical possession shall be taken by the condemnor.
   Landlord shall be entitled to retain all of the Security Deposit until such
   time as this Lease is terminated as to all of the Premises.

D. TEMPORARY TAKING

   If all or any portion of the Premises is condemned or otherwise taken for
   public or quasi-public use for a limited period of time (80), this Lease
   shall remain in full force and effect and Tenant shall continue to perform
   all terms, conditions and covenants of this Lease; provided, however, the
   rent and all other charges payable by Tenant to Landlord

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

(79)     ; provided, hovever, if more than ten percent (10%) of the Premises is
         taken in condemnation, then unless Landlord makes available additional
         replacement space in the Building, Tenant shall have the right to
         terminate the Lease, effective as of the date such portion of the
         Premises is taken.

(80)     (not to exceed six (6) consecutive months, if the taking materially
         impairs Tenant's ability to use the Premises)

<PAGE>

         (a) The worth at the time of award of the unpaid rent which had been
             earned at the time of termination;

         (b) The worth at the time of award of the amount by which the unpaid
             rent which would have been earned after termination until the time
             of award exceeds the amount of such rental loss that Tenant
             proves could have been reasonably avoided;

         (c) The worth at the time of award of the amount by which the unpaid
             rent for the balance of the Term after the time of award exceeds
             the amount of rental loss that Tenant proves could be reasonably
             avoided; and

         (d) Any other amount necessary to compensate Landlord
             for all the detriment proximately caused by Tenant's failure
             to perform its obligations under this Lease or which in the
             ordinary course of things would be likely to result therefrom,
             including, but not limited to, any(93) attorneys' fees,
             broker's commissions or finder's fees (not only in connection
             with the reletting of the Premises, but also that portion of
             any leasing commission paid by Landlord in connection with
             this Lease which is applicable to that portion of the Term
             which is unexpired as of the date on which this Lease is
             terminated); the then unamortized cost of any tenant
             improvements constructed for or on behalf of Tenant by or at the
             expense of Landlord or of any moving allowance or other
             concession made available to Tenant and/or paid by Landlord
             pursuant to this Lease; any costs for repairs, clean-up,
             refurbishing, removal (including the repair of any damage
             caused by such removal) and storage (or disposal) of Tenant's
             personal property, equipment, fixtures, and anything else that
             Tenant is required (under this Lease) to remove but does not
             remove; any costs for alterations, additions and renovations;
             and any other costs and expenses, including reasonable
             attorneys' fees and costs, incurred by Landlord in regaining
             possession of and reletting (or attempting to relet) the
             Premises.

    (2) The right to continue this Lease in effect and to enforce all of
        Landlord's rights and remedies under this Lease, including the right
        to recover rent and any other additional monetary charges as they
        become due, for as long as Landlord does not terminate Tenant's right
        to possession. Acts of maintenance or preservation, efforts to relet
        the Premises, the appointment of a receiver upon Landlord's initiative
        to protect its interest under this Lease or Landlord's withholding of
        consent to an Assignment or Subletting pursuant to the terms and
        conditions of Section XVI, above shall not constitute a termination of
        Tenant's right to possession.

    (3) The foregoing provisions of clause (2) shall apply even
        though Tenant has breached the Lease and abandoned the Premises, in
        which case Landlord shall have the right to re-enter the Premises
        with or without process of law to eject therefrom all parties in
        possession thereof, and, without terminating this Lease, at any
        time and from time to time, but without obligation to do so, to
        relet the Premises and the improvements located therein or any part
        or parts of any thereof for the account of Tenant, or otherwise, on
        such conditions as Landlord in its discretion may deem proper, with
        the right to make alterations and repairs to the Premises in
        connection therewith, and to receive and collect the rents
        therefor, and apply the same (i) first to the payment of such costs
        and expenses as Landlord may have paid, assumed or incurred: (A) in
        recovering possession of the Premises and said improvements,
        including attorneys' fees, and costs; (B) expenses for placing the
        Premises and said improvements in good order and condition, for
        decorating and preparing the Premises for reletting; (C) for making

---------------------
  (93) reasonable

                                         32

<PAGE>

        any alterations, repairs, changes or additions to the Premises that
        may be necessary or convenient; and (D) all other costs and
        expenses, including leasing and subleasing commissions, and charges
        paid, assumed or incurred by Landlord in or upon reletting the
        Premises and said improvements, or in fulfillment of the covenants
        of Tenant under this Lease; (ii) then to the payment of Monthly
        Rental, Tenant's Proportionate Share of Common Operating Costs, and
        other monetary obligations due and unpaid hereunder; and (iii) any
        balance shall be held by Landlord and applied in payment of future
        amounts as the same may become due and payable hereunder. Any such
        reletting may be for the remainder of the term of this Lease or for
        a longer or shorter period. The tenant(s) or subtenant(s)
        thereunder shall be under no obligation whatsoever with regard to
        the application by Landlord of any rent collected by Landlord from
        such tenant or subtenant to any and all sums due and owing or which
        may become due and owing under the provisions of this Lease, nor
        shall Tenant have any right or authority whatever to collect any
        rent whatever from such tenant(s) or subtenant(s). If Tenant has
        been credited with any rent received by such reletting and such
        rent shall not be promptly paid to Landlord by the tenant(s) or
        subtenant(s), or if such rentals received from reletting during any
        month are less than those to be paid during that month by Tenant
        hereunder, Tenant shall pay any such deficiency to Landlord. Such
        deficiency shall be calculated and paid monthly. Tenant shall also
        pay to Landlord as soon as ascertained, any costs and expenses
        incurred by Landlord in such reletting or in making such
        alterations and repairs not covered by the rentals received from
        such reletting. No taking of possession of the Premises by Landlord
        shall be construed as Landlord's acceptance of a surrender of the
        Premises by Tenant or an election of Landlord's part to terminate
        this Lease unless written notice of such intention is given to
        Tenant. Notwithstanding any such subletting without termination,
        Landlord may at any time thereafter elect to terminate this Lease
        for such previous breach. Election by Landlord to proceed pursuant
        to this clause (3) shall be made upon written notice to Tenant and
        shall be deemed an election of the remedy described in California
        Civil Code Section 1951.4 (providing that a lessor of real property
        may continue a lease in effect after a lessee's breach or
        abandonment and recover rent as it becomes due, if the lessee has
        the right to sublet or assign, subject only to reasonable
        limitations). If Landlord elects to pursue such remedy, unless
        Landlord relets the Premises, Tenant shall have the right to
        sublet the Premises and to assign its interest in this Lease,
        subject to all of the standards and conditions set forth in Section
        XVI. Landlord may elect to terminate the prosecution of such remedy
        at any time by written notice to Tenant, and the right of Tenant to
        sublet or assign shall terminate upon receipt by Tenant of such
        notice.

    (4) The right to have a receiver appointed for Tenant, upon
        application by Landlord, to take possession of the Premises and to
        apply any rental collected from the Premises and to exercise all
        other rights and remedies granted to Landlord pursuant to this
        subsection.

SECTION XXI. LATE PAYMENTS/INTEREST AND LATE CHARGES

A.  INTEREST

    Any amount due from Tenant to Landlord which is not paid when
    due shall bear interest at the maximum rate permitted by law from
    the date such payment is due until paid, except that amounts spent
    by Landlord on behalf of Tenant shall bear interest at such rate
    from the date of disbursement by Landlord which Tenant agrees is to
    compensate

                                     33

<PAGE>

    Landlord for Tenant's use of Landlord's money after it is due.
    Payment of such interest shall not excuse or cure any default by Tenant
    pursuant to this Lease. Such rate shall remain in effect after the
    occurrence of any breach or default hereunder by Tenant to and
    until payment of the entire amount due.

B.  LATE CHARGES

    TENANT HEREBY ACKNOWLEDGES THAT IN ADDITION TO LOST INTEREST,
    THE LATE PAYMENT BY TENANT TO LANDLORD OF RENT OR ANY OTHER SUMS
    DUE HEREUNDER WILL CAUSE LANDLORD TO INCUR OTHER COSTS NOT
    CONTEMPLATED IN THIS LEASE, THE EXACT AMOUNT OF WHICH WILL BE
    EXTREMELY DIFFICULT AND IMPRACTICABLE TO ASCERTAIN. SUCH OTHER
    COSTS INCLUDE, BUT ARE NOT LIMITED TO, PROCESSING, ADMINISTRATIVE
    AND ACCOUNTING COSTS, AND LATE CHARGES WHICH MAY BE IMPOSED UPON
    LANDLORD BY THE TERMS OF ANY ENCUMBRANCE COVERING THE PREMISES.
    ACCORDINGLY, IF ANY INSTALLMENT OF RENT OR ANY ADDITIONAL RENT OR
    OTHER SUM DUE FROM TENANT SHALL NOT BE RECEIVED BY LANDLORD WHEN
    SUCH AMOUNT SHALL BE DUE (WITHOUT REGARD TO ANY GRACE PERIOD
    GRANTED IN THIS LEASE), TENANT SHALL PAY TO LANDLORD AS ADDITIONAL
    RENT HEREUNDER A LATE CHARGE EQUAL TO (94) PERCENT ((95)%) OF SUCH OVERDUE
    AMOUNT. THE PARTIES HEREBY AGREE THAT (I) SUCH LATE CHARGE REPRESENTS A
    FAIR AND REASONABLE ESTIMATE OF THE COSTS LANDLORD WILL INCUR IN
    PROCESSING SUCH DELINQUENT PAYMENT BY TENANT, (II) SUCH LATE CHARGE
    SHALL BE PAID TO LANDLORD AS LIQUIDATED DAMAGES FOR EACH DELINQUENT
    PAYMENT, AND (III) THE PAYMENT OF THE LATE CHARGE IS TO COMPENSATE
    LANDLORD FOR THE ADDITIONAL ADMINISTRATIVE EXPENSE INCURRED BY LANDLORD
    IN HANDLING AND PROCESSING DELINQUENT PAYMENTS.

C.  CONSECUTIVE LATE PAYMENT OF RENT

    Following each (96) consecutive late payment of rent, Landlord shall
    have the option (i) to require that beginning with the first payment of
    rent next due, rent shall no longer be paid in monthly installments but
    shall be payable quarterly three (3) months in advance and/or (ii) to
    require that Tenant increase the amount, if any, of the Security Deposit
    by one hundred percent (100%), which additional Security Deposit shall

D.  NO WAIVER

    Neither assessment nor acceptance of partial payments, interest
    or late charges by Landlord shall constitute a waiver of Tenant's
    default with respect to such overdue amount, nor prevent Landlord

SECTION XXII. LIEN FOR RENT

SECTION XXIII. HOLDING OVER

         Any holding over by Tenant in the possession of the Premises, or any
         portion thereof, after the expiration or earlier termination of the
         Term, with or without the consent of Landlord, shall be construed to
         be a tenancy from month to month at (97) of the Monthly Rental
         herein specified for the last month in the Term (prorated on a
         monthly basis) unless Landlord shall specify a lesser amount for
         rent in its sole discretion, together with an amount estimated by
         Landlord for the monthly Common Operating Costs payable under this
         Lease, and shall otherwise be on the terms and conditions herein
         specified as far as applicable. Any holding over without Landlord's
         consent shall constitute a default by Tenant and shall entitle
         Landlord to pursue all remedies provided in this Lease and Tenant
         shall be liable for any and all direct or consequential damages or
         losses of Landlord resulting from Tenant's holding over without

shall also pay to Landlord all such amounts, including attorneys' fees,
incurred by Landlord in responding to any request by Tenant (a) to amend or
modify this Lease or (b) to prepare any statement or document in connection
with this Lease, including without limitation estoppel certificates or
subordination agreements or the like. Such amounts shall be payable upon
demand. In addition, if any action shall be instituted by either Landlord or
Tenant for the enforcement or interpretation of any of its rights or remedies
in or under this Lease, the prevailing party shall be entitled to recover from
the losing party all costs incurred by the prevailing party in said action
and any appeal therefrom, including reasonable attorneys' fees and court
costs to be fixed by the court therein. In the event Landlord is made a party
to any litigation between Tenant and any third party, then Tenant shall pay
all costs and attorneys' fees incurred by or imposed upon Landlord in
connection with such litigation; provided, however, if Landlord is ultimately
held to be liable, then Landlord shall reimburse Tenant for the cost of any
attorneys' fees paid by Tenant on behalf of Landlord.

SECTION XXV. MORTGAGE PROTECTION/SUBORDINATION

A.       SUBORDINATION

         The rights of Tenant under this Lease are and shall be, at the
         option of Landlord, either subordinate or superior to any mortgage
         or deed of trust (including a consolidated mortgage or deed of
         trust) constituting a lien on the Premises, Building or Project, or
         Landlord's interest therein or any part thereof, whether such
         mortgage or deed of trust has heretofore been, or may hereafter be,
         placed upon the Premises by Landlord, and to any ground or master
         lease if Landlord's title to the Premises or any part thereof is or
         shall become a leasehold interest. To further assure the foregoing
         subordination or superiority, Tenant shall, upon Landlord's request,
         together with the request of any mortgagee under a mortgage or
         beneficiary under a deed of trust or ground or master lessor,
         execute any instrument (including without limitation an amendment to
         this Lease that does not materially and adversely affect Tenant's
         rights or duties under this Lease), or instruments intended to
         subordinate this Lease, or at the option of Landlord, to make it
         superior to any mortgage, deed of trust, ground or master lease.
         Notwithstanding any such subordination, Tenant's right to occupy the
         Premises pursuant to this Lease shall remain in effect for the full
         Term as long as Tenant is not in default hereunder.

         (98)

B.       ATTORNMENT

         Notwithstanding subsection A, above, Tenant agrees (1) to attorn to
         any mortgagee of a mortgage or beneficiary of a deed of trust
         encumbering the Premises and to any party acquiring title to the
         Premises by judicial foreclosure, trustee's sale, or deed in lieu of
         foreclosure, and to any ground or master lessor, as the successor to
         Landlord hereunder, (2) to execute any attornment agreement reasonably
         requested by a mortgagee, beneficiary, ground or master lessor, or
         party so acquiring title to the Premises, and (3) that this Lease,
         subject to the rights under any outstanding non-disturbance agreement,
         at the option of such mortgagee, beneficiary, or ground or master
         lessor, or other party, shall remain in force notwithstanding any such
         judicial foreclosure, trustee's sale, deed in lieu of foreclosure, or
         merger of titles. Notwithstanding the foregoing, neither a

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

(98)     Notwithstanding the foregoing, this Lease shall not be subordinate to
         any future encumbrance in favor of Landlord's lender for the Project
         unless and until Tenant, Landlord and such lender shall have mutually
         executed and delivered a Subordination, Non-Disturbance and Attornment
         Agreement, substantially in the form of EXHIBIT 1 hereto (which Tenant
         shall, upon request by Landlord, execute and deliver, and Tenant's
         failure to do so within ten (10) days after written demand therefor by
         Landlord shall constitute a default by Tenant under this Lease).

                                      36

<PAGE>

         mortgagee of a mortgage or beneficiary of a deed of trust encumbering
         the Premises, any party acquiring title to the Premises by judicial
         foreclosure, trustee sale, or deed in lieu of foreclosure, or any
         ground lessor or master lessor, as the successor to Landlord hereunder,
         shall be liable or responsible for any breach of a covenant contained
         in this Lease that occurred before such party acquired its interest in
         the Premises or for any continuing breach thereof until after the
         successor Landlord has received the notice and right to cure as
         provided herein, and no such party shall be liable or responsible for
         any security deposits held by Landlord hereunder which have not been
         transferred or actually received by such party, and such party shall
         not be bound by any payment of rent or additional rent for more than
         two (2) months in advance.

C.       AMENDMENT

         If any lending institution with which Landlord has negotiated or may
         negotiate for financing for the Building or Project requires any
         changes to this Lease, Tenant shall promptly execute and deliver an
         amendment to this Lease prepared by Landlord and embodying such
         changes, so long as such changes do not materially increase Tenant's
         obligations (99) hereunder.(100) In the event that Tenant shall fail
         to execute and deliver such amendment within twenty (20) days after
         receipt thereof by Tenant, such failure shall constitute a default
         hereunder by Tenant and shall entitle Landlord to all remedies
         available to a landlord against a defaulting tenant pursuant to a
         written lease, including but not limited to those remedies set forth
         in Section XX.

SECTION XXVI. ESTOPPEL CERTIFICATE/FINANCIAL STATEMENTS

         to Landlord a statement in the form provided by Landlord (a) certifying
         that this Lease is unmodified and in full force and effect, or, if
         modified, stating the nature of such modification and certifying that
         this Lease, as so modified, is in full force and effect and the date
         to which the rent and other charges are in advance, if any; (b)

         defaults on the part of Landlord hereunder, or specifying such defaults

         acknowledging the amount of the Security Deposit held by Landlord; and
         (d) containing such other information regarding this Lease or Tenant as

         estoppel certificate within such time shall be conclusive upon Tenant
         that (i) this Lease is in full force and effect without modification
         except as may be represented by Landlord, (ii) to Tenant's knowledge
         there are no uncured defaults in Landlord's performance, (iii) no
         rent has been paid in advance except as set forth in this Lease, and

         for the purposes of calculating Tenant's Proportionate Share of Common
         Operating Costs, deprives Tenant of its options pursuant to Addendum
         Section XXXV.A., restricts Tenant's ability to access or use the
         Premises for the Permitted Use, reduces the parking spaces available to
         Tenant or requires Tenant to use Landlord's provider of janitorial
         services.

(101)    Upon Tenant's written request therefor, Landlord agrees to deliver
         to Tenant, not more than twice per calendar year, an estoppel
         certificate containing information of the type described in clauses
         (a) through (d) of the previous sentence.

         such statements and that said statements accurately and fairly depict
         the financial condition of Tenant. Said financial statements are an

         including a balance sheet and income statement, dated within ninety
         (90) days of the request from Landlord. (104)

SECTION XXVII. PARKING                             See Addendum Section XXXV.H.

    covenant, or condition or of any subsequent breach of the same or of any
    other term, covenant, or condition contained in this Lease. Landlord's

         ADDENDUM TO LEASE BETWEEN THE MUTUAL LIFE INSURANCE COMPANY
      OF NEW YORK, AS LANDLORD, AND EARTHLINK NETWORK, INC., AS TENANT,
                          DATED SEPTEMBER __, 1996

SECTION XXXV. ADDENDUM

A.  PREMISES

    (1)  RIGHT OF FIRST REFUSAL

         During the twelve (12) month period commencing on the Lease
         Commencement Date, Tenant shall have a one-time right of first
         refusal to lease the second floor of the Building (the "Expansion
         Space") from Landlord if, after the Lease Commencement Date and
         during the initial Term of this Lease, Landlord is or becomes
         interested in marketing such space. Landlord shall notify Tenant in
         writing upon receipt by Landlord from a third party of an offer for
         any portion of the Expansion Space (including all) that Landlord
         desires to accept. Tenant shall, within five (5) business days
         following its receipt of Landlord's notice, indicate in writing its
         intention to add to the Premises the entire portion of the Expansion
         Space (including all) so offered by Landlord on the terms and
         conditions specified herein. Any failure by Tenant to respond to
         Landlord's notice within such five (5) business day period, or any
         notice by Tenant specifying Tenant's acceptance of the Expansion
         Space on terms other than those set forth herein or of only a
         portion of the Expansion Space so offered by Landlord, shall cause
         Tenant's rights under this subsection A.(1) to terminate with
         respect to the Expansion Space so offered, and Landlord shall
         thereafter be free to lease the Expansion Space so offered to
         another party at any rate and on any terms Landlord chooses.

         If Tenant is entitled to and gives notice to Landlord within such
         five (5) business days of its desire to add the offered Expansion
         Space to the Premises, the entire Expansion Space shall be added to
         the Premises on the following terms and conditions: the Expansion
         Space so offered shall be delivered by Landlord to Tenant as soon as
         the same is available and shall be added to the Premises on the same
         terms and conditions set forth in this Lease with respect to the
         Premises (except that the Security Deposit for the Expansion Space
         shall be prorated such that Tenant shall deposit an amount equal to
         $1.455 per square foot of Rentable Area within the Expansion Space
         (per year) of the balance of the Term with respect to such Expansion
         Space, the Tenant Allowance shall be an amount equal to $2.50 per
         square foot of Rentable Area within the Expansion Space per year of
         the balance of the Term with respect to the Expansion Space and the
         Lease Commencement Date with respect to the Expansion Space shall be
         a date selected by Landlord as the date for Substantial Completion
         of Landlord's Work therein) AND the balance of the Expansion Space
         (i.e., the portion of the Expansion Space, if any, not covered by
         the third party offer) shall be added to the Premises and delivered
         by Landlord to Tenant on the day before the first anniversary of the
         date Landlord's notice offering Tenant the Expansion Space was given
         (or sooner, if mutually agreed in writing by Landlord and Tenant),
         on the terms and conditions set forth herein with respect to the
         Expansion Space identified in Landlord's notice.

         Notwithstanding anything to the contrary contained in this
         subsection A.(1), Landlord shall be required to offer any portion of
         the Expansion Space (including all) to Tenant, and Tenant shall be
         entitled to exercise its rights hereunder with respect thereto, only
         if, at the time of such offer and exercise, respectively, Tenant is
         not in default under any of the terms, conditions, provisions or

                                         45

<PAGE>

                  (b)      Within ten (10) days after such notice is given,
                           Tenant may elect in written notice to Landlord
                           either to (i) unequivocally accept such Monthly
                           Rental for the ensuing Additional Term as determined
                           by Landlord or (ii) submit the matter of the fair
                           market value for the purpose of determining Monthly
                           rental (only) to appraisal in accordance with (c)
                           below. Tenant's failure to make a written election
                           strictly in accordance with the preceding sentence
                           shall be deemed to be an acceptance of the Monthly
                           Rental as determined by Landlord, EXCEPT that an
                           equivocal acceptance of the Monthly Rental shall be
                           deemed an election by Tenant to submit the matter of
                           the fair market value for the purpose of determining
                           Monthly rental (only) to appraisal in accordance with
                           (c) below; and

                  (c)      If Tenant elects or is deemed to have elected to
                           submit the matter to appraisal in accordance with (b)
                           above, then each party shall, by written notice to
                           the other party given within ten (10) days after such
                           election or deemed election by Tenant, select an
                           appraiser. If either party shall fail to select an
                           appraiser in such manner and within such time, the
                           single appraiser actually selected shall perform the
                           appraisal. If each party timely and properly selects
                           an appraiser, the two appraisers selected by the
                           parties shall determine and attempt to agree on the
                           fair market rental value for the ensuing Additional
                           Term within thirty (30) days after their appointment;
                           if they are unable to so agree and their appraised
                           values differ by more than five percent (5%) in the
                           aggregate over the ensuing Additional Term, the two
                           appraisers shall, by written notice to Landlord and
                           Tenant, select a third appraiser within five (5) days
                           after expiration of the thirty (30) day period within
                           which they were to determine and agree on the fair
                           market rental, which third appraiser shall analyze
                           the fair market rental for the ensuing Additional
                           Term. If they cannot agree on a third appraiser
                           within such time period, or if both parties fail to
                           select an appraiser in the manner and within the time
                           herein provided, either party may have the third (or
                           sole, if applicable) appraiser appointed by
                           application to the presiding judge of the Los Angeles
                           County Superior Court or his or her designee. If
                           the appraised values of the first two appraisers are
                           within five percent (5%) in the aggregate over the
                           ensuing Additional Term, then Landlord shall
                           calculate the average of the two appraised values
                           as a flat rental rate for the ensuing Additional
                           Term, which average shall be the fair market rental
                           rate for such Additional Term.

                           The appraisers shall have the MAI designation and a
                           minimum of ten (10) years experience in the Los
                           Angeles County (Glendale/Pasadena) office market.
                           Each of the first two appraisers shall analyze the
                           fair market rental value of the Premises and shall
                           give written notice to the parties of his or her
                           appraisal within thirty (30) days following his or
                           her appointment or selection, but in no event later
                           than the commencement of the Additional Term. If a
                           single appraiser is used, his or her determination
                           shall be the fair market rental rate. If three
                           appraisers are used, the third appraiser shall select
                           one of the values determined by the first two
                           appraisers as the fair market rental rate. The cost
                           of the appraisals shall be shared equally by Landlord
                           and Tenant.

         (2)      The provisions of Sections III.B. and C. and EXHIBIT C shall
                  not apply to the Additional Term; and

         (3)      In the case of the First Additional Term, there shall be one
                  further option to extend the Term, and, in the case of the
                  Second Additional Term, there shall be no further options to
                  extend the Term. In the event Tenant fails or is not entitled
                  to exercise its option for the First Additional Term, or
                  Tenant is deemed

                                       47

<PAGE>

                  (pursuant to (1)(b) above) to have elected to terminate the
                  Lease upon receipt of Landlord's notice of the fair market
                  rental for the First Additional Term, then Tenant's option for
                  the Second Additional Term shall lapse and shall thereafter
                  not be exercisable by Tenant.

C.       COMMON OPERATING COSTS

         (1)      As used in this Lease, the term "Project Operating Costs"
                  shall include all costs of the type included in Common
                  Operating Costs applicable to the Common Areas and/or the
                  Project in general, such as real property taxes applicable to
                  the Common Areas, liability insurance with respect to the
                  Common Areas, maintenance service for the buildings within the
                  Project and repair costs with respect to the Project or any
                  equipment or machinery therein, but excluding costs which are
                  directly and separately identifiable to the operation and
                  maintenance of the Building or other buildings within the
                  Project. Common Operating Costs shall also include the
                  Building's share of Project Operating Costs, which shall
                  include, as appropriate, liability and other insurance with
                  respect to the Project generally, expenses of operating and
                  maintaining the parking structures, landscaping expenses for
                  exterior landscaping within the Project, security services
                  for the Project, property management fees and costs for a
                  manager and fees and other charges in connection with
                  membership in energy conservation associations and traffic
                  management organizations. To the extent that, in Landlord's
                  sole but reasonable judgment, it may not be equitable to
                  allocate certain Project Operating Costs on a pro rata basis
                  based upon the Rentable Areas of the buildings in the
                  Project, as the case may be, then Landlord may allocate the
                  same on such basis as Landlord, in its sole but reasonable
                  judgment, determines to be equitable.

         (2)      Notwithstanding anything to the contrary in the Lease,
                  Tenant's Proportionate Share of any and all costs of providing
                  janitorial service to the Premises which are includable in
                  Common Operating Costs in accordance with this Lease shall be
                  payable by Tenant, commencing on the Lease Commencement Date
                  and on the first day of each calendar month in the Term
                  thereafter, without any deduction for the Base Operating
                  Expense attributable to such janitorial services. In addition,
                  electrical service to the Premises will be separately metered,
                  and Tenant shall pay such separately metered costs directly to
                  the providers of such utilities as provided in Section IX.A.
                  of the Lease. Accordingly, costs attributable to tenant-area
                  janitorial services and/or to tenant-area electrical shall be
                  excluded from the Base Operating Expense, and Tenant's
                  Proportionate share of all Common Operating Costs, other than
                  such janitorial and electrical utility costs, shall be
                  determined by reference to the Base Operating Expense, as so
                  reduced.

         (3)      In the event that during all or any portion of any calendar
                  year, including the year used in calculating the Base
                  Operating Expense, the Building is not assessed as a completed
                  building, at such time as the Building is thereafter assessed
                  as a fully completed building, Landlord shall make an
                  adjustment to the Common Operating Costs for such year
                  (including the year for the Base Operating Expense, if
                  applicable) employing sound accounting and management
                  principles, to reflect the Common Operating Costs that would
                  have been paid or incurred by Landlord had the Building been
                  fully completed. In no event shall Landlord be entitled to
                  recover from tenants of the Project more than one hundred
                  percent (100%), in the aggregate, of the increase in Common
                  Operating Costs actually incurred by Landlord.

         (4)      Notwithstanding the foregoing, the following shall not be
                  included in Common Operating Costs (or shall be deducted
                  therefrom if included therein):

                  (a)      Costs incurred by Landlord in performing or providing
                           special work or services to a particular tenant of
                           the Project at such tenant's cost, and

                                       48
<PAGE>

                           costs of any additions, changes, replacements and
                           other items to tenant-area premises which are made
                           exclusively to prepare for a new tenant's occupancy
                           and which benefit only that particular tenant;

                  (b)      Compensation paid to officers and executives of
                           Landlord and of Landlord's managing agent who are not
                           directly involved in the management of the Project;

                  (c)      Costs which were previously included in Common
                           Operating Costs for either the base year (i.e., 1997)
                           or any other year during the Term which are
                           reimbursed to Landlord by insurance or condemnation
                           proceeds, under warranty or otherwise outside of
                           Common Operating Costs;

                  (d)      Costs of repairs or restoration incurred by reason of
                           fire or other casualty if and to the extent that
                           Landlord failed to obtain insurance against such fire
                           or casualty, if such insurance was available at
                           commercially reasonable rates and was required to be
                           carried by Landlord pursuant to this Lease; provided,
                           however, that the foregoing shall not apply to
                           preclude Landlord from including in Common Operating
                           Costs the deductible amounts under insurance policies
                           maintained by Landlord;

                  (e)      Any financing or refinancing costs and expenses

                           and rent under any ground or underlying lease;

                  (f)      Any real estate brokerage commissions or other costs
                           incurred in procuring tenants or any fee or other
                           form of compensation in lieu of such commission;

                  (g)      Any media advertising or any other advertising

                           the Building or any rentable space therein; provided,
                           however, that the foregoing shall not apply to
                           preclude Landlord from including in Common Operating
                           Costs, costs incurred in connection with signage for
                           the Project which is not exclusively for marketing

                           improvements (as reasonably determined by Landlord)
                           except: (i) to the extent the same are amortized over
                           the reasonable useful life of the item as reasonably
                           determined by Landlord and included in Common
                           Operating Costs as so amortized, or (ii) those
                           designed to reduce Common Operating Costs; provided,
                           however, in no event shall the foregoing apply to
                           preclude Landlord from including in Common Operating
                           Costs, costs of routine maintenance and repair;

                           Landlord, would be excluded from Common Operating
                           Costs pursuant to item (h) above; provided, however,

                           person or entity, if and to the extent that such
                           costs exceed the amount that would have been paid if
                           the services or materials had been procured from an

                           space in the Building or the Project which would not
                           otherwise be included in Common Operating Costs in
                           the absence of such default;

                  (m)      Fines or penalties for late payments or
                           non-compliance with laws assessed against Landlord as
                           a result of Landlord's negligence;

                           than the Common Areas and/or the management office at
                           the Building; and

                  (o)      Costs incurred in connection with bringing the
                           Premises, Building, Project or Common Areas into
                           initial compliance with any laws as in effect and as
                           applicable thereto as of the date of this Lease.

         (5)      Upon receipt of Tenant's notice protesting an Annual Statement
                  delivered to Tenant by Landlord pursuant to Section V.C. of
                  the Lease, Landlord will provide to Tenant reasonable
                  documentary back-up for those item(s) protested by Tenant.
                  Tenant shall pay to Landlord upon demand as additional rent
                  the costs and expenses incurred by Landlord in responding to
                  such request. In the event that, upon reviewing the back-up so
                  provided by Landlord, Tenant disagrees with the amount charged
                  by Landlord to Tenant for any such item, Tenant may so notify
                  Landlord. If Landlord agrees with the findings of Tenant, then
                  an appropriate adjustment shall be made. In the event that
                  there is a disagreement, then Landlord and Tenant shall each
                  identify an accountant, who shall meet to resolve the dispute,
                  whose determination shall be binding upon Landlord and Tenant.
                  Any such dispute must be resolved within nine (9) months after
                  the end of the year to which the Annual Statement applies.

D.       SECURITY DEPOSIT

         All or any portion of the Security Deposit described in Section I.L. of
         the Lease may be provided by Tenant in the form of one or more
         irrevocable letters of credit from an independent financial institution
         selected by Tenant and acceptable to Landlord in the form of EXHIBIT
         "I" hereto (collectively (if applicable) the "Letter of Credit"). If
         Tenant elects to provide a Letter of Credit to satisfy all or a portion
         of its obligations pursuant to Sections I.L. and VI. of the Lease,
         Tenant shall deliver to Landlord, concurrently with the execution and
         delivery of this Lease, cash and/or a Letter of Credit in the aggregate
         amount of Eight Hundred Thousand Dollars ($800,000.00) as security for
         Tenant's full and faithful performance of its obligations and payment
         of amounts due pursuant to this Lease. Notwithstanding anything to the
         contrary herein, in no event shall Landlord be required to accept a
         letter of credit in excess of, in the aggregate, Four Hundred Thousand
         Dollars ($400,000.00) from any one financial institution.
         Notwithstanding the foregoing sentence, (a) Landlord hereby agrees that
         the Letter of Credit initially provided to Landlord upon execution and
         delivery of this Lease may be drawn on Union Bank of California in the
         entire amount required to be posted (i.e., $800,000.00) and (b) prior
         to renewing the Letter of Credit annually, Tenant shall give notice to
         Landlord of the financial institution(s) with whom Tenant proposes to
         renew the Letter of Credit for the ensuing year, and Landlord shall
         have the right to approve such financial institution(s) for the renewal
         Letter of Credit, and may require Tenant to provide two Letters of
         Credit if the aggregate amount thereof is greater than Four Hundred
         Thousand Dollars ($400,000.00) if Landlord, in its sole but reasonable
         discretion, deems the financial strength of the proposed financial
         institution to be insufficient. Any Letter of Credit

                                       50

<PAGE>

         provided hereunder shall be as available to Landlord as if the same
         were a cash security deposit made pursuant to Section VI. of the Lease.
         Any such Letter of Credit shall be renewed by Tenant annually, on or
         before its expiration date and, if Landlord does not receive an
         original replacement letter of credit at least three (3) business days
         prior to the expiration date of an expiring Letter of Credit, then
         Landlord shall have the right to draw the as-yet unexpired Letter of
         Credit in full, provided, however, that in the absence of the
         occurrence, prior to the applicable anniversary date set forth below,
         of any event giving rise to Landlord's right to use, apply or retain
         all or any part of the Security Deposit pursuant to Section VI. of
         the Lease (herein, an "Event"), then Tenant's obligation shall be to
         renew the Letter of Credit in an applicable amount (in the aggregate,
         if applicable, with other Letters of Credit provided hereunder) set
         forth below. The occurrence of an Event prior to any anniversary date
         set forth below shall cause Tenant's obligation to provide the Letter
         of Credit pursuant to this Addendum Section to continue thereafter
         without any of the subsequent reductions described herein.

E.       HAZARDOUS MATERIALS

         (1)      To the best of Landlord's knowledge, Landlord has not itself
                  used the Building or Project in violation of governmental laws
                  and regulations governing Hazardous Materials applicable to
                  the Project and, Landlord's actual knowledge, the Building
                  does not contain any Hazardous Materials in violation of law
                  and/or friable asbestos, and the only non-friable asbestos
                  discovered in the Building is in roofing materials located on
                  the roof of the Building. Notwithstanding anything to the
                  contrary in this Lease, in the event that Hazardous Materials
                  are discovered in the Project, the presence of which is not
                  caused by a breach of the obligations of Tenant set forth in
                  Section VI.C. of the Lease, Landlord shall, at Landlord's sole
                  cost and expense, remove, remediate, or otherwise deal with
                  such Hazardous Materials if, as and when required by
                  applicable governmental authorities.

         (2)      Due to the former existence of a landfill in the area of the
                  Project, a methane venting system has been installed at the
                  Project and on adjacent properties. In addition, a nearby
                  property owner, whose property is closer to the Southern
                  California Edison (SCE) power lines which are in the general
                  geographic area of the Project, has experienced some
                  interference with MacIntosh computers adjacent to the walls of
                  its premises nearest the power lines, which may be caused by
                  electric and magnetic fields which may be being induced by the
                  SCE power lines. Landlord is unaware of any similar or related
                  complaints from the occupant of the other building at the
                  Project or from the former occupant of the Building.
                  Information with respect to the possible effects of power
                  lines on equipment and human health is available from SCE, and
                  Landlord will make available to Tenant upon request a copy of
                  such SCE information and any other environmental reports in
                  Landlord's possession regarding the Project. Tenant accepts
                  the Premises "AS-IS" with respect to the SCE power lines and
                  the effect thereof.

                                       51

F.       SERVICE AND UTILITIES

         Access to the Building is available 24 hours per day, 7 days per week
         via a card-key security system. Landlord may assess a charge for any
         access cards for such system provided to Tenant and/or its employees.
         Utilities are, subject to Section XXXIII.K. below, available 24 hours
         per day, subject to Tenant's payment to Landlord of the reasonable
         costs thereof, as determined by Landlord. In the event that the
         Premises are not separately zoned such that after-hours HVAC can be
         made available to the Premises (only), and Tenant requests after-hours
         HVAC service to the Premises at the same time as a tenant or occupant
         of another area of the Building which is in the same zone as the
         Premises requests the same, then (unless the fees to Tenant and such
         other tenant or occupant are prorated by Landlord) any fees received by
         Landlord for such after-hours HVAC from such other tenant or occupant
         for any period of time for which Tenant is assessed a charge for
         after-hours HVAC shall be applied to reduce the charge imposed on
         Tenant.

G.       JANITORIAL SERVICE

         So long as Tenant is the only occupant of the Building, Tenant may
         provide janitorial service to the Premises, the scope and the provider
         of which are subject to Landlord's prior written approval. Landlord
         hereby approves Omni Facility Group of Pasadena as that initial
         provider of Tenant's janitorial service; provided, however, that
         Landlord reserves the right to approve the proposed scope of such
         provider's service and the contract therefor, and further reserves
         the right to require Tenant to replace such provider (and any
         subsequent provider) if Landlord determines that health, cleanliness
         or maintenance conditions are adversely affected by the standard and
         level of service provided. If Tenant elects to contract directly for
         janitorial service, Tenant shall provide to Landlord a copy of the
         contract therefor for Landlord's approval. In the event that another
         tenant or occupant takes occupancy of the Building, Landlord shall
         have the right to require that janitorial service to the Premises be
         provided by Landlord's contractor, at Tenant's cost as provided in
         Addendum Section XXXV.C.(2) above, in accordance with Landlord's
         standard janitorial specifications, a copy of which are attached to
         the Lease as EXHIBIT G, but which are subject to change from time to
         time.

H.       PARKING

         Landlord shall make available for the use of Tenant, its employees,
         contractors, agents and invitees up to 4 unreserved parking spaces per
         1,000 square feet of Rentable Area, free of charge (subject to
         applicable governmental requirements) for the initial Term. If and so
         long as Tenant is the only tenant in the Building, Tenant may, with
         Landlord's prior written consent, restrict access to the parking area
         serving the Building so long as Landlord and its agents, employees and
         invitees are provided free access thereto and any improvements in
         connection therewith are treated as "Alterations" within the meaning of
         Section XII. of the Lease.

I.       SIGNAGE

         Notwithstanding anything to the contrary in Section XXVIII. of the
         Lease, Tenant may install on or before the Lease Commencement Date, at
         Tenant's sole cost and expense, one sign indicating Tenant's name on
         the Building and may erect a monument sign for the Project, and, on
         such date (if any) as the entire second floor is added to the Premises
         pursuant to Addendum Section XXXV.A. above upon exercise by Tenant of
         its rights thereunder, a second sign above the entrance to the
         Building, and in each case the contents, design, size, materials,
         location and method of application of each such sign shall be subject
         to Landlord's prior written approval and compliance with the CC&Rs for
         the Project, all applicable sign programs and all other governmental
         requirements then in effect for the Project. From and after the date,
         if any, that Tenant leases the entire Building, and so long as there
         is no other occupant of the Building, Landlord shall not

         NOW, THEREFORE, IN CONSIDERATION OF the foregoing recitals, and for
other good and valuable consideration, the receipt and adequacy of which are
hereby acknowledged, the parties hereto hereby agree as follows:

of the Lease is hereby amended to be Fifty-Four Thousand Seven Hundred
Forty-Eight (54,748) square feet.

                  b. Tenant's Proportionate Share of Common Operating Costs set
forth in Section I.Q. of the Lease is hereby amended to be forty-nine and
fifty-eight one-hundredths percent (49.58%).

                  c. EXHIBIT D to the Lease is hereby deleted and replaced with
Exhibit D to this Amendment.

                  d. The Tenant Allowance (as defined in EXHIBIT C to the Lease)

in the Premises).

         3. LEASE IN EFFECT. Landlord and Tenant acknowledge and agree that the
Lease, as hereby amended, remains in full force and effect in accordance with
its terms. To the extent that any provision of this Amendment shall conflict
with the Lease as in effect prior to the date hereof, this Amendment shall
prevail.

         IN WITNESS WHEREOF, the undersigned have executed this Amendment to be
effective as of the day and year first above written.

restoration or similar rights set forth in the Lease. Provided that Tenant has
performed all of its obligations hereunder, Tenant may remove all Tenant

such item which was paid for, in whole or in part, by Landlord or any wiring or
cabling unless Landlord requires such removal).
