--------
approximately 78,895 square feet each, or 157,790 square feet total, situated
upon the Land (hereinafter defined) commonly known as The Reserve at Green's

term "Buildings" shall mean Building A and Building B.

Commencement Date shall mean May 1, 2000.
-----------------


Land shall mean that certain tract of land situated in Harris County, Texas and

more particularly described on Exhibit A attached hereto and hereby made a part
                               ---------

----


                                  ARTICLE II.

     Section 2.1  Premises.  The Premises demised by this Lease consist of all
                  --------
of Building A consisting of 78,895 rentable square feet (the "Phase I Space")
(See Exhibit B), approximately 30,000 rentable square feet of space in Building
B (the "Phase II Space") (See Exhibit B) and approximately 32,000 additional
rentable square feet of space in Building B (the "Phase III Space") (See Exhibit
B) (collectively, the "Premises") for a total of 140,895 rentable square feet of
                       --------
area. The Premises are shown on the site plan attached as Exhibit B, and are
                                                          ---------
hereby made a part hereof by this reference. All square footage utilized in this
Lease has been, or will be as to future space made, in accordance with "Standard
Method for Measuring Floor Area in Office Buildings", published by the
Secretariat, Buildings Owners and Managers Association International (ANSI/BOMA
Z65.1-1996), approved June 7, 1996. Unless otherwise specifically designated,
all references to square footage or square feet in this Lease are to rentable
square footage or square feet. It is understood between both parties that for
purposes of the Lease Agreement, there shall be no add on factor.
Notwithstanding the foregoing, Landlord and Tenant acknowledge and agree that
the portion of the Premises located in Building B includes an electrical room.
For purposes of determining the rentable area of the Premises, the Premises has
only been allocated a pro rata share of the square footage of the electrical
room based upon the rentable area of the balance of the Premises in Building B
as compared to the rentable area of Building B. Further, Tenant agrees that
although such electrical room is included within the Premises, such room shall
remain a common area of the Building and shall be under Landlord's sole control
and Landlord shall have access to and from such electrical room and shall have
the right to utilize parts of the Premises for Landlord's use of and access to
the electrical room. Within thirty (30) days after the Phase II Commencement
Date (as that term is hereinafter defined) and the Phase III Commencement Date
(as that term is hereinafter defined), Landlord shall have the right with
Gensler, Tenant's architect, to remeasure the Phase II Space and the Phase III
Space in accordance with the foregoing standard and if determined by Landlord to
be different than the rentable square footage of the Phase II Space and the
Phase III Space described above, then the rentable square footage of the
Premises and all payments of Base Rent, Additional Rent and other sums hereunder
shall be adjusted accordingly. Tenant shall have
<PAGE>

the right to decrease the rentable area of the Phase II Space and the Phase III
Space subject to the following terms and conditions:

  (i)   Such right shall be exercised by Tenant, if at all, on or before
February 1, 2000 by written notice to Landlord;

  (ii)  Landlord and Tenant must agree upon the demising lines for the Phase II
Space and the Phase III Space within ten (10) days after Tenant's election to
adjust;

  (iii) Tenant shall have no right to decrease the total rentable area of the
Premises to less than 135,000; and

  (iv)  The Phase II Space and the Phase III Space must be contiguous along the
entire common demising line.

In the event that either (i) Landlord elects to remeasure the Premises using
Tenant architect, Gensler, as provided hereinabove, or (ii) Tenant elects to
decrease the rentable area of the Premises, then the rentable area of the
Premises shall be automatically adjusted in this Lease for all purposes as well
as Base Rent, Tenant's Pro Rata Share, the Tenant Improvement Allowance and all
other amounts herein which vary with the rentable square feet of the Premises.

In the event that Tenant leases less than all of the Project, Landlord covenants
and agrees to lease the balance of the Project to other third party office
tenants whose uses are consistent with the use and operation of the Project and
other similarly situated office buildings in the vicinity.

     Section 2.2  Term.  The Term of this Lease shall begin on the Commencement
                  ----
Date and shall continue in full force and effect for the Term of this Lease
unless extended or sooner terminated in accordance with the provisions of this
Lease. Notwithstanding the foregoing, Rent due hereunder with respect to the
Phase II Space shall not begin until the earlier of (i) July 1, 2000 or (ii) the
date Tenant begins use and beneficial occupancy of the Phase II Space (the
"Phase II Commencement Date") and Rent due hereunder with respect to the Phase
III Space shall not begin until the earlier of (a) September 1, 2000 or (b) the
date Tenant begins use and beneficial occupancy of the Phase III Space (the
"Phase III Commencement Date"), subject, however, to the terms of Special
Stipulation No. 2 in Exhibit C of this Lease. After the occurrence of the Phase
                     ---------
II Commencement Date, Tenant and Landlord shall execute a certificate in the
form attached hereto as Exhibit D stipulating and agreeing to the Phase II
                        ---------
Commencement Date and after the occurrence of the Phase III Commencement Date,
Tenant and Landlord shall execute a certificate in the form attached hereto as
Exhibit D stipulating and agreeing to the Phase III Commencement Date. Landlord
---------
acknowledges and agrees that use and beneficial occupancy of the Premises shall
not include construction and construction related activities such as the storing
of construction materials.

     Section 2.3  Use.  The Premises are to be used only for general office
                  ---
purposes which shall include, but not be limited to, employee training, employee
lunch room and/or kitchen facilities (including vending machines for Tenant's
use only), printing facilities and incidental storage and warehouse facilities
relating thereto, meeting and conference rooms, operation of an employee
cafeteria, operation of an employee delicatessen (solely for the use of Tenant's
employees and guests), telecommunication facility, data processing and computer
facilities and equipment and for no other business or purpose without the prior
written consent of Landlord which consent shall not be unreasonable withheld,
delayed or conditioned, provided such use is consistent with the use of
similarly situated office buildings in the area. No act shall be done in or
about the Premises that is unlawful or that will increase the existing rate of
insurance on the Building. In the event of a breach of this covenant, Tenant
shall immediately cease the performance of such unlawful act or such act that is
increasing or has increased the existing rate of insurance and shall pay to
Landlord any and all increases in insurance premiums resulting from such breach.
Tenant shall not commit or allow to be committed any waste upon the Premises, or
any public or private nuisance or other act or thing which disturbs the quiet
enjoyment of any other tenant in the Building. If any of Tenant's office
machines or equipment unreasonably disturb any other tenant in the Building,
then Tenant shall provide adequate insulation, or take such other action as may
be necessary to eliminate the noise or disturbance at its sole cost and expense.
Tenant shall not, without Landlord's prior consent except as outlined and
specifically agreed to within this Lease, install any equipment, machine,
device, tank or vessel which is subject to any federal, state or local
permitting requirement. Tenant, at its expense, shall comply with all applicable
laws, statutes, ordinances and governmental rules, regulations or requirements
governing the installation, operation and removal of any such equipment,
machine, device, tank or vessel. Tenant, at its expense, shall comply with all
applicable laws, statutes, ordinances, governmental rules, regulations or
requirements, and the applicable provisions of any recorded documents now
existing or hereafter in effect relating to its use, operation or occupancy of
the Premises and shall observe such reasonable rules and regulations as may be
adopted and made available to Tenant by Landlord from time to time for the
safety, care and cleanliness of the Premises or the Building and for the
preservation of good order therein. The current rules and regulations for the
Building are attached hereto as Exhibit F. Without limiting the foregoing,
                                ---------
Tenant agrees to be wholly responsible at Tenant's sole cost and expense for any
accommodations or alterations which need to be made to the interior of the
Premises to comply with the provisions of the Americans With Disabilities Act of
1990, as amended. Landlord shall be wholly responsible at Landlord's sole cost
and expense (subject to reimbursement pursuant to and in accordance with the
terms of Section 3.2 of this Lease, if applicable) for any accommodations or
alterations which need to be made to the exterior of the Premises and/or the
Project to comply with the provisions of the Americans with Disabilities Act of
1990, as amended, and the Texas Accessibility Standards, except for any
accommodations or alterations required by Tenant's Work (as that term is defined
in Exhibit E) or Tenant's particular use of the Premises. Notwithstanding the
   ---------
foregoing, Landlord shall be responsible, at its sole cost and expense (not
subject to any reimbursement hereunder), for the completion of the Building in
compliance with all applicable laws, ordinances, rules and regulations.

                                 ARTICLE III.

     Section 3.1  Rental Payments.
                  ---------------

     (a)  Base Rent.  Commencing on the Commencement Date and continuing
          ---------
thereafter throughout the Term, Tenant shall pay the Base Rent described in this
paragraph, which is due and payable each Lease Year during the Term hereof in
twelve (12) equal installments on the first (1st) day of each calendar month
during the Term, and Tenant shall make such installments to Landlord at
Landlord's address specified in this Lease (or such other address as may be
designated by Landlord from time to time) monthly in advance.  Base Rent during
the Term shall be as follows:

     Months of           Base Rent Per         Base Rent    Base Rent
       Term           Rentable Square Foot     Annually      Monthly
       ----           --------------------     --------      -------

     1 - 2                  $10.125         $  798,811.87  $ 66,567.66
     3 - 4                  $10.125         $1,102,561.80  $ 91,880.15
     5 - 9                  $10.125         $1,426,561.80  $118,880.15
     10 - 60                $12.775         $1,799,993.60  $149,994.46
     61 - 120               $14.125         $1,990,141.80  $165,845.15

Base Rent is subject to adjustment as provided in Section 2.1 above.  So long as
Tenant is not then in default under this Lease, in the event Tenant has paid
Landlord any Prepaid Rent such Prepaid Rent shall be applied to the first (1st)
monthly installment of Base Rent due hereunder.


     (b)  Partial Month.  If the Commencement Date is other than the first (1st)
          -------------
day of a calendar month or if this Lease expires or terminates on a day other
than the last day of a calendar month, then the installments of Base Rent for
such month or months shall be prorated based upon multiplying the applicable
Base Rent by a fraction, the numerator of which shall be the number of days of
the Term occurring during said commencement or termination month, as the case
may be, and the denominator of which shall be the number of days in such month.


     (c)  Payment; Late Charge; Past Due Rate.  The Base Rent, the Additional
          -----------------------------------
Rent (hereinafter defined), any Prepaid Rent and any and all other payments,
which Tenant is obligated to make to Landlord under this Lease, shall constitute
and are sometimes hereinafter collectively referred to as "Rent".  Tenant shall
                                                           ----
pay all Rent and other sums of money as shall become due from and payable by
Tenant to Landlord or to such other person or persons as may be designated by
notice from Landlord to Tenant from time to time in lawful money of the United
States of America at the times and in the manner provided in this Lease, without
demand, deduction, abatement, setoff, counterclaim or prior notice.  Tenant
hereby acknowledges that late payment to Landlord of Rent or other sums due
hereunder will cause Landlord to incur costs not contemplated by this Lease, the
exact amount of which will be extremely difficult to ascertain.  If any Rent or
other sum due to Landlord from Tenant is not received on or before five (5) days
after its due date, then Tenant shall pay to Landlord immediately upon
Landlord's demand therefor a late charge in an amount equal to three percent
(3%) of such overdue amount, plus any reasonable attorneys' fees and costs
incurred by Landlord by reason of Tenant's failure to pay Rent and other charges
when due hereunder; provided, however, if Tenant fails to pay Base Rent
hereunder within such 5-day period more than twice in any Lease Year, then
thereafter such late charge shall be assessed immediately upon Tenant's failure
to pay on or before the due date for any such Base Rent.

     Section 3.2  Additional Rent.

Taxes"); provided, however, that if at any time during the Term the present
-----    --------  -------
method of taxation or assessment shall be so changed that the whole or any part
of the taxes, assessments, levies, impositions or charges now levied, assessed
or imposed on real estate and the improvements thereof shall be changed and as a
substitute therefor, or in lieu of or in addition thereto, taxes, assessments,
levies, impositions or charges shall be levied, assessed or imposed wholly or
partially as a capital levy or otherwise on the rents received from the Project
or the rents reserved herein or any part thereof, then such substitute or
additional taxes, assessments, levies, impositions or charges, to the extent so
levied, assessed or imposed, shall be deemed to be included within the Real
Estate Taxes to the extent that such substitute or additional tax would be
payable if the Project were the only property of Landlord subject to such tax.

     (ii) Operating Expense Exclusions.  Notwithstanding the foregoing,
          -----------------------------
Operating Expenses shall not include the following:

          a.   Cost of repairs or other work occasioned by fire, windstorm or

          tenant.

          e.   Costs incurred by Landlord for alterations or improvements which
          are considered capital improvements or replacements under generally

          j.     Any costs, fines or penalties incurred due to violations by
          Landlord or any governmental rule or authority, except if and to the
          extent such costs, fines or penalties are the subject of a good faith
          appeal by Landlord.

          k.     Compensation paid to officers and executives of Landlord (but
          it is understood that the on-site building manager and other on-site
          employees below the grade of building manager may carry a title such
          as vice president and the salaries and related benefits of these
          officer/employees of Landlord would be allowable Operating Expenses)
          and any general corporate overhead of the Landlord.

          l.     Cost incurred in the removal of asbestos or other substances
          considered to be detrimental to the health or the environment of

          m.     Costs associated with bringing the Building in compliance of
          general building codes, which codes were enacted prior to Tenant's
          occupancy, whether such work is performed before or after the
          Commencement Date of this Lease.

          (iii)  Tenant's Right to Audit.  In the event that within ninety (90)
                 -----------------------
days after Tenant's receipt of the Statement (as that term is hereinafter
defined) for the prior calendar year, Tenant reasonably believes that certain of
the Operating Expenses charged by Landlord include costs that are not properly
included within the term "Operating Expenses" or that Landlord has erred in
calculating same, Tenant shall have the right to audit Landlord's books and
records in accordance with this paragraph.  Tenant shall exercise such audit
right by providing Landlord with a written notice of Tenant's exercise of such
audit right within such 90-day period and a statement enumerating reasonably
detailed reasons for Tenant's objections to the Statement issued by Landlord
(the "Audit Notice").  Upon the receipt by Landlord of an Audit Notice, Landlord
shall instruct its property manager at the Building to meet with a designated
employee of Tenant (the "Tenant Representative") to discuss the objections set
forth in the Audit Notice.  Landlord shall provide the Tenant Representative
with reasonable access to Landlord's books and records at the Building relating
to Operating Expenses for the calendar year in question in order to attempt to
resolve the issues raised by Tenant in the Audit Notice.  If, within thirty (30)
days after Landlord's receipt of the Audit Notice, Landlord and Tenant are
unable to resolve Tenant's objections, then not later than ten (10) days after
the expiration of such 30-day period, Tenant shall notify Landlord if Tenant
wishes to employ an independent, reputable certified public accounting firm
charging for its services on an hourly rate or fixed fee (and not a contingent
fee) basis ("Acceptable Accountants") to inspect and audit Landlord's books and
records for the Building relating to the objections raised in Tenant's
statement.  Such audit shall be limited to a determination of whether or not
Landlord calculated the Operating Expenses in accordance with the terms and
conditions of this Lease and normal and customary accounting methods used by
owners of similar buildings in the area for calculating Tenant's Expense
Increase.  All costs and expenses of any such audit shall be paid by Tenant.
Any audit performed pursuant to the terms of this section shall be conducted
only by the Acceptable Accountants at the offices of Landlord's property manager
at the Building.  Notwithstanding anything contained herein to the contrary,
Tenant shall be entitled to exercise its audit right pursuant to this section
only in strict accordance with the foregoing procedures no more often than once
per calendar year and each such audit shall relate only to the calendar year
most recently ended.  In the event that Tenant fails to notify Landlord within
the foregoing 90-day period that Tenant objects to the Statement, then Tenant's
right to audit such year's Statement shall be null and void.  In the event such
inspection or audit by Tenant shall show that the Operating Expenses for any
Lease Year shall have been overstated by five percent (5%) or more, Landlord
agrees to pay the reasonable out-of-pocket costs of any audit conducted by
Tenant's independent certified public accountant (not to exceed, in any event,
the lesser of (i) Five Thousand Dollars ($5,000.00) or (ii) the total amount of
the overstatement) and to refund to Tenant, within thirty (30) days of the date
of receipt by Landlord of a copy of Tenant's audit, all or any portion of the
overpayment paid by Tenant as Additional Rent for the Lease Year in question.
In the event such inspection or audit by Tenant shall show that the Operating
Expenses for any Lease Year have been understated, then Tenant shall pay to
Landlord, within thirty (30) days of receipt by Tenant of the audit results,
such underpayment of Additional Rent.  In the event that Landlord disputes that
the results of Tenant's audit or inspection accurately reflects the terms and
conditions of this Lease and the application of such terms and conditions to the
Operating Expenses for such Lease Year, Landlord shall have the right to submit
such dispute to the American Arbitration Association for binding arbitration on
an expedited basis.  Landlord and Tenant agree to comply with the foregoing
provisions regarding refund/payment of the sums due after the arbitration
decision is rendered.

          (iv)   "Adjustment Period" means each calendar year occurring during
                  -----------------
the Term beginning with calendar year 2000, which shall be the first Adjustment
Period.

          (v)    "Tenant's Pro Rata Share" means the percentage calculated by
                  -----------------------
dividing the rentable area of the Premises (numerator) by the rentable area of
the Building (denominator), and expressing the fraction as a percentage.

     (b)  Gross-Up Adjustment.  If the Building is less than fully occupied or
          -------------------
if standard Landlord services are not provided to the entire Building during any
Adjustment Period, then Operating Expenses for such Adjustment Period shall be
"grossed up" by Landlord to that amount of Operating Expenses that, using
reasonable projections, would normally be expected to be incurred during the
Adjustment Period if the Building was ninety-five percent (95%) occupied and
receiving building standard Landlord services during the Adjustment Period, as
determined under generally accepted accounting principles consistently applied.

                                       5
<PAGE>

     (c)  Payment by Tenant.  Tenant hereby agrees to pay Landlord as additional
          -----------------
rent (the "Additional Rent") Tenant's Pro Rata Share of Operating Expenses for
           ---------------
any Adjustment Period.


     (d)  Manner of Payment.
          -----------------

          (i)    Landlord may give Tenant notice of Landlord's estimate of
amounts payable under this Section 3.2 for each Adjustment Period based upon
                           -----------
generally accepted accounting principles consistently applied. By the first day
of each month during the Adjustment Period, Tenant shall pay Landlord one-
twelfth (1/12th) of the estimated amount. If for any reason the estimate is not
given before the Adjustment Period begins, Tenant shall continue to pay on the
basis of the previous year's estimate, if any, until the month after the new
estimate is delivered to Tenant in writing.

          (ii)   Within one hundred twenty (120) days after each Adjustment
Period ends, or as soon thereafter as reasonably practical, Landlord shall give
Tenant a statement (the "Statement") showing the: (A) actual Operating Expenses
                         ---------
for the Adjustment Period; (B) the amount of Tenant's Pro Rata Share of such
Operating Expenses; (C) the amount, if any, paid by Tenant during the Adjustment
Period towards Tenant's Pro Rata Share of Operating Expenses; and (D) the amount
Tenant owes towards Tenant's Pro Rata Share of Operating Expenses or the amount
Landlord owes as a refund. Delay by Landlord in providing to Tenant any
Statement shall not relieve Tenant from the obligation to pay any Additional
Rent upon the rendering of such Statements.

          (iii)  If the Statement shows that the actual amount Tenant owes for
the Adjustment Period is less than the estimate of Tenant's Pro Rata Share of
Operating Expenses paid by Tenant during the Adjustment Period, Landlord shall
return the difference (the "Overpayment").  If the Statement shows that the
                            -----------
actual amount Tenant owes is more than any estimate of Tenant's Pro Rata Share
of Operating Expenses paid by Tenant during the Adjustment Period, Tenant shall
pay the difference (the "Underpayment").  The Overpayment or Underpayment shall
                         ------------
be paid within thirty (30) days after the Statement is delivered to Tenant.


          (iv)   During any Adjustment Period in which this Lease is not in
effect for a complete calendar year, unless it was ended due to Tenant's
default, Tenant's obligation for Additional Rent for those Adjustment Periods
shall be prorated by multiplying the Additional Rent for the Adjustment Period
by a fraction expressed as a percentage, the numerator of which is the number of
days of the Adjustment Period included in the Term and the denominator of which
is 365.

     (e)  Prepaid Rent.  Upon execution of this Lease, tenant shall pay to
          ------------
Landlord the Prepaid Rent.


                                  ARTICLE IV.


     Section 4.1  Services.
                  --------

     (a)  Services Provided.  Landlord shall furnish to Tenant while Tenant is
          -----------------
occupying the Premises:

          (i)    Cold domestic water for Tenant's restrooms and toilets in
locations as shown on the Building Plans which at a minimum shall provide
adequate water service for two (2) sets of restrooms for each of the Buildings
along with necessary water/sewer service for standard office water or as
required by applicable law or code.

          (ii)   Locks on the exterior entry doors; provided, however, Landlord
shall have no responsibility to prevent, and shall not be liable to Tenant for,
any liability or loss to Tenant, its agents, employees and visitors arising out
of losses due to theft, burglary, or damage or injury to persons or property
caused by persons gaining access to the Premises, and Tenant hereby releases
Landlord from all liability for such losses, damages or injury.  Landlord
acknowledges that Tenant plans to install a separate access control system
and/or expand the provided system, subject to Landlord's approval as to the
plans and specifications which approval shall not be unreasonably withheld,
conditioned or delayed.  Tenant shall have the right to remove any security
equipment that Tenant has installed in the Premises either during, or after, the
Term and any renewals thereof.  Tenant acknowledges that pursuant to the terms
of Section 5.1(c) of this Lease, Landlord may require Tenant to remove such
access control system upon the expiration or earlier termination of this Lease.
Further, in the event that Tenant installs such system, then Tenant shall
provide to Landlord a master key or access card to allow Landlord access to the
Premises as prescribed elsewhere in this Lease.

          (iii)  Electrical capacity to the Premises in the amount of eleven
(11.00) watts per square foot of rentable area (the "Building standard rated
electrical design load").  The Building Standard rated electrical design load
shall be the total watts per rentable square foot available to the Premises for
all purposes including, without limitation, operation of the HVAC system.


                 Should Tenant desire electrical capacity in excess of the
Building standard rated electrical design load, any additional equipment,
including, without limitation, high voltage panels shall be installed by
Landlord at Tenant's sole cost and expense, subject to Tenant's price approval
of the costs and expenses of such additional equipment.

                                       6
<PAGE>

          Except as expressly provided above, Tenant shall be responsible, at
its sole cost and expense, for all services and utilities to the Premises,
excluding those outlined in the Operating Expenses including, without
limitation, heating, ventilation and air conditioning.  Landlord and Tenant
acknowledge and agree that electricity serving the Premises shall (and other
utilities may) be separately metered or submetered at Tenant's sole cost and
expense and Tenant shall be solely responsible for paying all such costs
directly to the utility provider.  Further, Landlord shall not be obligated to
furnish any janitorial services to the Premises.  Tenant shall at its expense
throughout the Term cause janitorial services to be provided to the Premises by
contracting directly with a janitorial service company approved by Landlord
which approval shall not be unreasonably withheld, delayed or conditioned.
Tenant shall not be obligated to pay Landlord any pro-rata share of janitorial
services, and or any other Operating Expenses for which Tenant pays separately
from Operating Expenses, which Landlord provides exclusively to any portion of
the Buildings occupied by third parties.


     (b)  Cessation of Services. To the extent the services described in Section
          ---------------------                                          -------
4.1(a) of this Lease require electricity, gas and water supplied by public
------
utilities , Landlord's covenants thereunder shall only impose on Landlord the
obligation to use its best efforts to cause the applicable public utilities to
furnish the same.  Failure by Landlord to furnish the services described in this
Section 4.1 to any extent, or any cessation thereof, shall not render Landlord
-----------
in default hereunder or liable in any respect for damages to either person or
property, or be construed as an eviction of Tenant, or work an abatement of
Rent, or relieve Tenant from fulfillment of any covenant or agreement hereof,
except as provided herein below.  In addition to the foregoing, should any of
the equipment or machinery break down, cease to function properly for any cause,
or be intentionally turned off for testing or maintenance purposes, Tenant shall
have no claim for abatement or reduction of Rent or damages on account of an
interruption in service occasioned thereby or resulting therefrom; provided,
                                                                   --------
however, Landlord agrees to use diligent efforts to repair said equipment or
-------
machinery and to restore said services.

     (c)  Interruption of Service.  Notwithstanding anything to the contrary
          -----------------------
contained in this Lease, if Tenant cannot reasonably use the Premises for
Tenant's intended business operations by reason of any interruption in services
to be provided by Landlord (and Tenant does not in fact use the Premises) and
such condition exists for three (3) consecutive business days, then Tenant's
Base Rent shall be equitably abated for that portion of the Premises that Tenant
is unable to use for Tenant's intended business operations until such service is
restored to the Premises. Tenant shall not, however, be entitled to any
abatement of Base Rent if the interruption or abatement in service or the
failure by Landlord to furnish such service is the result of force majeure or is
the result of an interruption or abatement in service of a public utility
(collectively, an "Unavoidable Interruption"). By way of example only, there
shall be no abatement of Base Rent if Landlord is unable to furnish water or
electricity to the Premises if no water or electricity is then being made
available to the Building by the supplying utility company or municipality. At
the time of the loss of service, Tenant must give written notice promptly to
Landlord of the loss of service and its claim for abatement and Tenant only
shall be entitled to abatement of Base Rent in proportion to the area rendered
unusable. Landlord may prevent or stop abatement by providing substantially the
same service in similar quality and quantity by temporary or alternative means
until the cause of the loss of service can be corrected. Such abatement shall be
Tenant's sole remedy for loss of service and Tenant shall have no right to
terminate this Lease, unless such interruption of service continues for sixty
(60) consecutive days, and is not an Unavoidable Interruption, in which case
Tenant shall have such rights and remedies available to Tenant at law or in
equity.

     Section 4.2  Occupancy of Premises.  Tenant shall, throughout the Term of
                  ---------------------
this Lease, at its own expense, maintain all improvements on the Premises in the
manner set forth in Section 5.1 of this Lease, and shall keep the Premises free
from waste, damage or nuisance, and shall deliver up the Premises in a clean and
sanitary condition at the expiration or termination of this Lease or the
termination of Tenant's right to occupy the Premises by Tenant, in good repair
and condition, reasonable wear and tear and damage by casualty, as set forth in
Section 6.3 of this Lease excepted. In the event Tenant should neglect to
maintain and/or return the Premises in such manner, Landlord shall have the
right, but not the obligation after providing Tenant with thirty (30) days
written notice specifying the particulars of such correction to be made,
together with a reasonable time thereafter to correct the same, to cause repairs
or corrections to be made, and any reasonable costs therefor shall be payable by
Tenant to Landlord within ten (10) days of demand therefor by Landlord. Upon the
expiration or termination of this Lease or the termination of Tenant's right to
occupy the Premises by Tenant, Landlord shall have the right to reenter and
resume possession of the Premises. No act or thing done by Landlord or any of
Landlord's agents (hereinafter defined) during the Term of the Lease shall be
deemed an acceptance of a surrender of the Premises, and no agreement to accept
a surrender of the Premises shall be valid unless the same be made in writing
and executed by Landlord.

     Section 4.3  Landlord's Entry.  Tenant shall permit Landlord and its agents
                  ----------------
to enter the Premises at all reasonable times to inspect the same; to show the
Premises to prospective tenants (only within twelve (12) months of the
expiration of the term of this Lease and with notice to Tenant), or interested
parties such as prospective lenders and purchasers; to exercise its rights under
this Lease; to discharge Tenant's obligations when Tenant has failed to do so
within the time required under this Lease or within a reasonable time after
written notice from Landlord, whichever is earlier, though Landlord shall in no
event be obligated to do so; to post notices of nonresponsibility and similar
notices and "For Sale" signs at any time and to place "For Lease" signs upon or
adjacent to the Building or the Premises at any time within twelve (12) months
of the expiration of the term of this Lease. Tenant shall permit Landlord and
its agents to enter the Premises at any time in the event of an emergency. When
reasonably necessary during such as emergency, Landlord may temporarily close
entrances, doors, or other facilities without liability to Tenant by reason of
such closure.

                                       7

     Section 4.4  Hazardous Materials.
                  -------------------

     (a)  As used in this Lease, the term "Hazardous Materials" shall mean and
include any substance that is or contains petroleum, asbestos, polychlorinated
biphenyls, lead, or any other substance, material or waste which is now or is
hereafter classified or considered to be hazardous or toxic under any federal,
state or local law, rule, regulation or ordinance relating to pollution or the
protection or regulation of human health, natural resources or the environment
(collectively "Environmental Laws") or poses or threatens to pose a hazard to
               ------------------
the health or safety of persons on the Premises or any adjacent property.

     (b)  Tenant agrees that during its use and occupancy of the Premises it
will not permit Hazardous Materials to be present on or about the Premises
except in a manner and quantity necessary for the ordinary performance of
Tenant's business and that it will strictly comply with all Environmental Laws
relating to the use, storage or disposal of any such Hazardous Materials. In
connection therewith, Landlord acknowledges that Tenant may install and utilize
printing facilities in the Premises so long as such facilities do not occupy
more than 20,000 rentable square feet of area.

     (c)  Tenant shall give prompt written notice to Landlord of:  (A) becoming
aware of any use, generation, manufacture, production, storage, release,
discharge or disposal of any Hazardous Materials on, under, from or about the
Premises or the migration thereof to or from other property; (B) the
commencement, institution or threat of any proceeding, inquiry or action by or
notice from any local, state or federal governmental authority with respect to
the use or presence of any Hazardous Materials on the Premises or the migration
thereof from or to other property; (C) all claims made or threatened by any
third party against Tenant or the Premises relating to any damage, contribution,
cost recovery, compensation, loss or injury resulting from any Hazardous
Materials; (D) Tenant's discovery of any occurrence or condition on any real
property adjoining or in the vicinity of the Premises that could cause the
Premises or any part thereof to be subject to any restrictions on the ownership,
occupancy, transferability or use of the Premises under any Environmental Law,
or any regulation adopted in accordance therewith, or to be otherwise subject to
any restrictions on the ownership, occupancy, transferability or use of the
Premises under any Environmental Law; and (E) obtaining knowledge of any
occurrence of expense by any governmental authority or others in connection with
the assessment, containment or removal of any Hazardous Materials located on,
under, from or about the Premises or any property adjoining or in the vicinity
of the Premises.

     (d)  If Tenant's use of Hazardous Materials on or about the Premises
results in a release, discharge or disposal of Hazardous Materials on, in, at,
under, or emanating from, the Premises or the Land, Tenant shall provide
immediate notice of the same to Landlord and agrees to investigate, clean up,
remove or remediate such Hazardous Materials in full compliance with (i) the
requirements of (A) all Environmental Laws and (B) any governmental agency or
authority responsible for the enforcement of any Environmental Laws; and (ii)
any additional requirements of Landlord that are reasonably necessary to protect
the value of the Premises or the Land. Provided, however, Tenant shall not take
any action under this Section 4.4(d) without first obtaining Landlord's consent
                      --------------
thereto. Landlord shall also have the right, but not the obligation, to take
whatever action with respect to any such Hazardous Materials that it deems
reasonably necessary to protect the value of the Premises or the Land. All costs
and expenses paid or incurred by Landlord in the exercise of such right shall be
payable by Tenant upon demand.

     (e)  Upon reasonable notice to Tenant, Landlord may inspect the Premises
for the purpose of determining whether there exists on the Premises any
Hazardous Materials or other condition or activity that is in violation of the
requirements of this Lease or of any Environmental Laws. The right granted to
Landlord herein to perform inspections shall not create a duty on Landlord's
part to inspect the Premises, or liability on the part of Landlord for Tenant's
use, storage or disposal of Hazardous Materials, it being understood that Tenant
shall be solely responsible for all liability in connection therewith.

     (f)  Landlord shall have the right, no more than once per year, to engage
or cause Tenant to engage, each at Landlord's sole cost and expense, an
environmental consultant acceptable to both Landlord and Tenant, to review
compliance by Tenant with all applicable laws and standards existing at such
time with respect to the practice relating to contamination or hazardous waste
compliance methods, conditions and procedures and Tenant's development of a plan
to identify, contain and remediate problems caused by such Hazardous Materials.
The foregoing sentence shall not be deemed to require an environmental
compliance audit, unless otherwise reasonably recommended pursuant to such
review. In the event that Landlord reasonably believes that there may be a
violation or threatened violation by Tenant of any Environmental Law or a
violation or threatened violation by Tenant of any covenant under this Article
IV, Landlord is authorized, but not obligated, by itself, is agents, employees
or workmen to enter at any reasonable time, so long as Landlord uses its
reasonable best efforts to not unduly interfere with Tenant's normal conduct of
business, upon any part of the Premises for the purposes of inspecting the same
for Hazardous Materials and Tenant's compliance with this Article IV, and such
inspections may include, without limitation, soil borings. Tenant agrees to pay
to Landlord, upon Landlord's demand, all actual and customary expenses, costs or
other amounts incurred by Landlord in performing any inspection for the purposes
set forth in this Section 4.4 only if it is found that Tenant has violated any
provision of this Section 4.4.

     (g)  Tenant shall surrender the Premises to Landlord upon the expiration or
earlier termination of this Lease free of debris, waste or Hazardous Materials
placed on or about the Premises by Tenant or its agents, employees, contractors
or invitees, and in a condition which complies with all Environmental Laws.

     (h)  Tenant agrees to indemnify and hold harmless Landlord and Landlord's
Related Parties (as defined in Section 5.3 of the Lease) from and against any
                               -----------
and all claims, losses (including, without limitation, loss

                                       8
<PAGE>

in value of the Premises or the Land), judgments, demands, causes of action,
liabilities and expenses (including reasonable attorney's fees and costs arising
from the same) sustained by Landlord attributable to (i) any Hazardous Materials
placed on or about the Premises by Tenant or its agents, employees, contractors
or invitees or (ii) Tenant's breach of any provision of this Section. Landlord
agrees to indemnify and hold harmless Tenant from and against any and all
claims, losses, judgements, demands, causes of actions, liabilities and expenses
(including reasonable attorneys' fees and costs arising from the same) sustained
by Tenant attributable to any Hazardous Materials placed on or about the
Premises by Landlord or its agents, employees, contractors and invitees.

     (i)  The provisions of this Section shall survive the expiration or earlier
termination of this Lease.

     (j)  Landlord represents and warrants that to the best of its knowledge, as
     of the Commencement Date, the Project and Premises are free of any
     Hazardous Materials.


                                  ARTICLE V.

  Section 5.1  Leasehold Improvements.
               ----------------------

     (a)  Acceptance of Premises.  Tenant has made a complete inspection of the
          ----------------------
Premises including the  physical condition of the Building and any improvements,
expenses, operation and maintenance, zoning, status of title and use that may be
made of the Premises and every other matter or thing affecting the Premises, and
shall accept the Premises in their "AS IS," "WHERE IS," and "WITH ALL FAULTS"
condition on the Commencement Date without recourse to Landlord, subject to the
terms of Exhibit E attached hereto and hereby made a part hereof.  Landlord has
         ---------
not made and does not make any representations and warranties whatsoever with
respect to the Premises or otherwise with respect to this Lease, except as
otherwise provided herein and may be set forth on Exhibit E hereto.  Landlord
                                                  ---------
shall have no obligation to furnish, equip or improve the Premises except for
the satisfactory completion of all work to be performed by Landlord as otherwise
provided for herein.


     (b)  Improvements and Alterations.  Tenant shall not make or allow to be
          ----------------------------
made (except as otherwise provided in this Lease) any improvements, alterations
or physical additions (including fixtures) in or to the Premises or the Project
in excess of $50,000 for any one alteration, addition or improvement or which
affect any structural or building system components of the Premises or Project
(mechanical, electrical or plumbing) or which under applicable laws require a
building, electrical, plumbing or other permit, without first obtaining the
written consent of Landlord, including Landlord's written approval of Tenant's
contractor(s) and of the plans, working drawings and specifications relating
thereto except as set forth in Exhibit E.  Approval by Landlord of any of
Tenant's drawings and plans and specifications prepared in connection with any
alterations, improvements, modifications or additions to the Premises or the
Project shall not constitute a representation or warranty of Landlord as to the
adequacy or sufficiency of such drawings, plans and specifications, or
alterations, improvements, modifications or additions to which they relate, for
any use, purpose or conditions, but such approval shall merely be the consent of
Landlord as required hereunder.  Except as otherwise expressly provided in
Exhibit E attached hereto, any and all furnishing, equipping and improving of or
---------
other alteration and addition to the Premises shall be: (i) made at Tenant's
sole cost, risk and expense, and in the case of alterations, improvements or
additions requiring a permit by Tenant and if it is necessary for Landlord to
employ a third party consultant to review Tenant's plans and specifications,
then Tenant shall reimburse Landlord for Landlord's actual reasonable costs
incurred in connection with such consultant; (ii) performed in a prompt, good
and workmanlike manner with labor and materials of such quality as the initial
tenant improvements; (iii) constructed in accordance with all plans and
specifications approved in writing by Landlord, which approval shall not be
unreasonably withheld, delayed, or conditioned prior to the commencement of any
such work only if such work is in excess of $50,000 (as described hereinabove);
(iv) prosecuted diligently and continuously to completion so as to minimize
interference with the normal business operations of other tenants in the
Building; and (v) performed by contractors approved in writing by Landlord which
approval shall not be unreasonable withheld, delayed or conditioned.  Landlord
and Tenant will mutually agree to a list of contractors or subcontractors who
may be employed by Tenant for any such work at the time the proposed work is to
be completed.  Tenant shall have no (and hereby waives all) rights to payment or
compensation for any such item.  Tenant shall notify Landlord upon completion of
such alterations, improvements, modifications or additions and Landlord shall
inspect same for workmanship and compliance with the approved plans and
specifications.  Tenant and its contractors shall comply with all reasonable
requirements Landlord may impose on Tenant or its contractors with respect to
such work (including but not limited to, insurance, indemnity and bonding
requirements) only if modification is in excess of $50,000, and shall deliver to
Landlord a complete copy of the "as-built" or final plans and specifications for
all alterations or physical additions so made in or to the Premises within
thirty (30) days of completing the work.  Tenant shall not place safes, vaults,
filing cabinets or systems, libraries or other heavy furniture or equipment
within the Premises after the initial occupancy of the Premises without
Landlord's prior written consent which consent shall not be unreasonably
withheld, delayed or conditioned.

     (c)  Title to Alterations.  All Alterations, physical additions,
          --------------------
modifications or improvements in or to the Premises (including fixtures) shall,
when made, become the property of Landlord except as provided for in the Lease
(security system, generator, UPS, etc.) and shall be surrendered to Landlord
upon termination or expiration of this Lease or termination of Tenant's right to
occupy the Premises, whether by lapse of time or otherwise, without any payment,
reimbursement or compensation therefor; provided, however, that Tenant shall
                                        --------  -------
retain title to and shall remove from the Premises movable equipment or
furniture owned by Tenant, repair any damage caused thereby, and return the
Premises to their preexisting condition.  Notwithstanding any of the foregoing
to the contrary, Landlord may require Tenant to remove all alterations,
additions or improvements to the Premises including, without limitation, any
computer, satellite or telecommunications equipment or hardware, whether or not
such

                                       9

alterations, additions, or improvements are located in the Premises upon the
expiration or earlier termination of this Lease or the termination of Tenant's
right to possession of the Premises and restore the same to Building standard
condition, reasonable wear and tear excepted, provided that Landlord advises
Tenant in writing that such must be removed when Landlord grants its consent for
any such alterations. The rights conferred to Landlord under this Section 5.1(c)
shall be in addition to (and not in conflict with) any other rights conferred on
Landlord by this Lease, in equity or at law.

     (d)  Personal Property Taxes; Sales, Use and Excise Taxes.  Tenant shall be
          ----------------------------------------------------
responsible for and shall pay ad valorem taxes and other taxes, assessments or
charges levied upon or applicable to Tenant's personal property, the value of
Tenant's leasehold improvements in the Premises in excess of Building standard
(and if the taxing authorities do not separately assess Tenant's leasehold
improvements, Landlord may make a reasonable allocation of the taxes assessed on
the Project to give effect to this Section 5.1(d)) and all license fees and
                                   --------------
other fees or charges imposed on the business conducted by Tenant on the
Premises before such taxes, assessments, charges or fees become delinquent.
Tenant shall also pay to Landlord with all Rent due and owing under this Lease
an amount equal to any sales, rental, excise and use taxes levied, imposed or
assessed by the State or any political subdivision thereof or other taxing
authority upon any amounts classified as rent.


     (e)  Repairs, Maintenance and Property Management.  Tenant shall, at its
          --------------------------------------------
sole cost and expense, repair and maintain the Premises during the Term of this
Lease including, without limitation, all components thereof such as the HVAC
systems, plumbing and electrical and all other installations reflected on the
Final Plans including, if necessary, the replacement of such components.  All
repairs, alterations or additions that affect the Project's structural
components or base building mechanical, electrical or plumbing systems shall be
made by Landlord or its contractors only at Landlord's sole cost and expenses
(subject, however, to reimbursement pursuant to and in accordance with the terms
of Section 3.2 of this Lease, if applicable).  Landlord shall repair and
maintain the Landlord's Work as defined in Exhibit E, unless such repairs or
                                           ---------
maintenance is due to Tenant's negligence or willful misconduct.  Landlord's
repairs and maintenance costs may be included in Operating Expenses if otherwise
permitted pursuant to the terms of this Lease.  Unless otherwise provided
herein, Landlord shall not be required to make any improvements to or repairs of
any kind or character to the leasehold improvements located in the Premises
during the Term.

Tenant's obligation to maintain the Premises shall include the obligation to
repair, maintain and replace (if necessary,) the HVAC system and Tenant hereby
agrees to enter into a preventative maintenance/service contract with a
maintenance contractor approved by Landlord (which approval shall not be
unreasonably withheld, delayed or conditioned) for servicing all air
conditioning, heating, ventilating and other such equipment within or servicing
the Premises.

     Section 5.2  Liens.  Tenant shall keep the Premises and the Building free
                  -----
from any liens, including but not limited to liens filed against the Premises by
any governmental agency, authority or organization, arising out of any work
performed, materials ordered or obligations incurred by or on behalf of Tenant,
and Tenant hereby agrees to indemnify and hold Landlord, its agents, employees,
independent contractors, officers, directors, partners, and shareholders
harmless from any liability, cost or expense for such liens. Tenant shall cause
any such lien imposed to be released of record by payment or posting of the
proper bond acceptable to Landlord within ten (10) business days after the
earlier of imposition of the lien or written request by Landlord. If Tenant
fails to remove any lien within the prescribed ten (10) business day period,
then Landlord may do so at Tenant's expense and Tenant's reimbursement to
Landlord for such amount, including attorneys' fees and costs, shall be deemed
Additional Rent. Tenant shall have no power to do any act or make any contract
which may create or be the foundation for any lien, mortgage or other
encumbrance upon the reversion or other estate of Landlord, or of any interest
of Landlord in the Premises.

     Section 5.3  Indemnification.  Tenant shall defend, indemnify and hold
                  ---------------
harmless Landlord, its agents, employees, officers, directors, partners and
shareholders ("Landlord's Related Parties") from and against any and all
               --------------------------
liabilities, judgments, demands, causes of action, claims, losses, damages,
costs and expenses, including reasonable attorneys' fees and costs, arising out
of the use, occupancy, conduct, operation, or management of the Premises by, or
the willful misconduct or negligence of, Tenant, its officers, contractors,
licensees, agents, servants, employees, guests, invitees, or visitors in or
about the Building or Premises or arising from any breach or default under this
Lease by Tenant, or arising from any accident, injury, or damage, howsoever and
by whomsoever caused, to any person or property, occurring in or about the
Building or Premises. This indemnification shall survive termination or
expiration of this Lease. This provision shall not be construed to make Tenant
responsible for loss, damage, liability or expense resulting from injuries to
third parties caused by the negligence or willful misconduct of Landlord, or its
officers, contractors, licensees, agents, employees, or invitees or arising from
any breach or default under this Lease by Landlord.

     Section 6.1    Condemnation.
                    ------------

     (a)     Total Taking. In the event of a taking or damage related to the
             ------------
exercise of the power of eminent domain, by any agency, authority, public
utility, person, corporation or entity empowered to condemn property (including
without limitation a voluntary conveyance by Landlord in lieu of such taking or
condemnation) (individually, a "Taking") of (i) the entire Premises, (ii) so
                                ------
much of the Premises as to prevent or substantially impair its use by Tenant
during the Term of this Lease or (iii) portions of the Building or Project
required for reasonable access to, or reasonable use of, the Premises
(individually, a "Total Taking"), the rights of Tenant under this Lease and the
                  ------------
leasehold estate of Tenant in and to the Premises shall cease and terminate as
of the date upon which title to the property taken passes to and vests in the
condemnor or the effective date of any order for possession if issued prior to
the date title vests in the condemnor ("Date of Taking").
                                        --------------

     (b)     Partial Taking. In the event of a Taking of only a part of the
             --------------
Premises or of a part of the Project which does not constitute a Total Taking
during the Term of this Lease (individually, a "Partial Taking"), the rights of
                                                --------------
Tenant under this Lease and the leasehold estate of Tenant in and to the portion
of the property taken shall cease and terminate as of the Date of Taking, and an
adjustment to the Rent shall be made based upon the reduced area of the
Premises.

     (c)     Termination by Landlord or Tenant. In the event of a Taking of the
             ---------------------------------
Building (other than the Premises) such that, in Landlord's or Tenant's
reasonable opinion, the Building cannot be restored in a manner that makes its
continued operation practically or economically feasible, or if a portion of the
Premises or the Project is taken which renders the Premises (or the remaining
balance thereof) unusable for Tenant's intended business purposes, at Tenant's
sole but reasonable discretion,  Landlord or Tenant may terminate this Lease by
giving notice to the other party within thirty (30) days after the date notice
of such Taking is received by Landlord and Landlord provides Tenant a copy of
such notice.

     (d)     Rent Adjustment. If this Lease is terminated pursuant to this
             ---------------
Section 6.1, Landlord shall refund to Tenant any prepaid unaccrued Rent and any
-----------
other sums due and owing to Tenant (less any sums then due and owing Landlord
by Tenant), and Tenant shall pay to Landlord any remaining sums due and owing
Landlord under this Lease, each prorated as of the Date of Taking where
applicable.

     (e)     Repair. If this Lease is not terminated as provided for in this
             ------
Section 6.1, then Landlord at its expense shall promptly repair and restore the
-----------
Building, Project and/or the Premises to approximately the same condition that
existed at the time Tenant entered into possession of the Premises, wear and
tear excepted (and Landlord shall have no obligation to repair or restore
Tenant's improvements to the Premises or Tenant's Property), except for the part
taken, so as to render the Building or Project as complete an architectural unit
as practical, but only to the extent of the condemnation award received by
Landlord for the damage.

     (f)     Awards and Damages. Landlord reserves all rights to damages and
             ------------------
awards paid because of any Partial or Total Taking of the Premises or the
Project. Further, Tenant shall not make claims against Landlord or the
condemning authority for damages including, without limitation, any damages
based upon the value of Tenant's leasehold estate; provided, however, Tenant may
claim and recover from the condemning authority a separate award for Tenant's
moving expenses, business dislocation damages, Tenant's Property and any other
award that would not reduce the award payable to Landlord.

     Section 6.2    Force Majeure.  Neither Landlord nor Tenant shall be
                    -------------
required to perform any term, provision, agreement, condition or covenant in
this Lease (other than the obligations of Tenant to pay Rent as provided herein)
so long as such performance is delayed or prevented by "Force Majeure", which
                                                        -------------
shall mean acts of God, strikes, injunctions, lockouts, material or labor
restrictions by any governmental authority, civil riots, floods, fire, theft,
public enemy, insurrection, war, court order, requisition or order of
governmental body or authority, and any other cause not reasonably within the
control of Landlord or Tenant and which by the exercise of due diligence
Landlord or Tenant is unable, wholly or in part, to prevent or overcome. Neither
Landlord nor any mortgagee shall be liable or responsible to Tenant for any loss
or damage to any property or person occasioned by any Force Majeure, or for any
damage or inconvenience which may arise through repair or alteration of any part
of the Project as a result of any Force Majeure.

     Section 6.3    Fire or Other Casualty.
                    ----------------------

     (a)     Damage. If any portion of the Premises shall be destroyed or
             ------
damaged by fire or any other casualty, Tenant shall immediately give notice
thereof to Landlord. If any portion of the Premises or Project shall be
destroyed or damaged by fire or any other casualty then, at the option of
Landlord, Landlord may restore and repair the portion of the Premises or Project
damaged and, if the Premises are rendered untenantable in whole or in part by
reason of such casualty as determined by Landlord, Tenant shall be entitled to
an equitable percentage abatement of the Rent hereunder (subject to the
limitation in Section 7.3(c) below) until such time as the damaged portion of
              --------------
the Premises (exclusive of any of Tenant's Property or Tenant's improvements)
are repaired or restored by Landlord to the extent required hereby or either
Tenant or Landlord may terminate this Lease whereupon all Rent accrued up to the
time of such termination and any other sums due and owing shall be paid by
Tenant to Landlord (less any sums then due and owing Tenant by Landlord) and any
remaining sums due and owing by Landlord to Tenant shall be paid to Tenant. In
no event shall Landlord have any obligation to repair or restore any such
destruction or damage.

                                      11
<PAGE>

     (b)     Repair. Landlord shall use reasonable efforts to give Tenant
             ------
written notice of its decisions, estimates or elections under this Section 6.3
                                                                   -----------
within forty five (45) days after any such damage or destruction. If Landlord
has elected to repair and restore the Premises or other portion of the Project,
this Lease shall continue in full force and effect, and the repairs will be made
within two hundred ten (210) days subject to the provisions of Section 6.2 of
                                                               -----------
this Lease. Should the repairs not be completed within that period, both
Landlord and Tenant shall each have the option of terminating this Lease by
written letter of termination. If this Lease is terminated as herein permitted,
Landlord shall refund to Tenant any prepaid Rent (unaccrued as of the date of
damage or destruction) and any other sums due and owing by Landlord to Tenant
(less any sums then due and owing Landlord by Tenant) and any remaining sums due
and owing by Tenant to Landlord shall be paid to Landlord. If Landlord has
elected to repair and reconstruct the Premises or other portion of the Project
to the extent stated above, the Term will be extended for a time equal to the
period from the occurrence of such damage to the completion of such repair and
reconstruction with Rent during such extended period being the same as the last
rent paid by Tenant immediately prior to such extended period. If Landlord
elects to rebuild the Premises or other portion of the Project, Landlord shall
only be obligated to restore or rebuild the Premises or other portion of the
Project to approximately the same condition as existed at the time Tenant
entered into possession of the Premises, wear and tear excepted and not be
required to rebuild, repair or replace any part of Tenant's Property or Tenant's
leasehold improvements. Notwithstanding anything contained in this Lease to the
contrary, if Landlord shall elect to repair and restore the Premises or other
portion of the Project pursuant to this Section 6.3, in no event shall Landlord
                                        -----------
be required to expend under this Article VII any amount in excess of the
                                 -----------
proceeds actually received from the insurance carried by Landlord pursuant to
Section 6.4(a) of this Lease. Landlord shall not be liable for any inconvenience
--------------
or annoyance to Tenant or injury to the business of Tenant resulting in any way
from such damage or destruction or the disregard of the repair thereof.

     (c)     Negligence of Tenant.  Notwithstanding the provisions of Sections
             --------------------                                     --------
6.3(a) and 6.3(b) of this Lease, if the Premises, the Project or any portion
-----------------
thereof, are damaged by fire or other casualty resulting from the fault or
negligence of Tenant or any of Tenant's agents, the Rent under this Lease will
not be abated during the repair of that damage, and Tenant will be liable to
Landlord for the cost and expense of the repair and restoration of the Premises,
the Project or any part thereof, caused thereby to the extent that cost and
expense is not covered by insurance proceeds (including without limitation the
amount of any insurance deductible).

     Section 6.4    Insurance.
                    ---------

     (a)     Landlord shall maintain, or cause to be maintained, standard fire
and extended coverage insurance on the Buildings and Building standard tenant
improvements (excluding leasehold improvements by Tenant in excess of Building
standard and Tenant's Property) in amounts considered by Landlord to be
reasonable and customary. The insurance required to be obtained by Landlord may
be obtained by Landlord through blanket or master policies insuring other
entities or properties owned or controlled by Landlord.

     (b)     Tenant shall, at its sole cost and expense, procure and maintain
during the Term of this Lease all such policies of insurance as Landlord may
require, including without limitation comprehensive general liability insurance
(including personal injury liability, premises/operation, property damage,
independent contractors and broad form contractual coverage in support of the
indemnifications of Landlord by Tenant under this Lease) in amounts of not less
than a combined single limit of $1,000,000; comprehensive automobile liability
insurance; business interruption insurance; contractual liability insurance;
property insurance with respect to Tenant's Property, and all leasehold
improvements, alterations and additions in excess of Building standard, to be
written on an "all risk" basis for full replacement cost; worker's compensation
and employer's liability insurance; and comprehensive catastrophe liability
insurance; all maintained with companies, on forms and in such amounts as
Landlord may, from time to time, reasonably require and with Landlord to be
included as an additional insured. With respect to all third party insurance
carriers, the insurer must be licensed to do business in the state in which the
Building is located. In the event that Tenant fails to take out or maintain any
policy required by this Section 6.4 to be maintained by Tenant, such failure
                        -----------
shall be a defense to any claim asserted by Tenant against Landlord by reason of
any loss sustained by Tenant that would have been covered by such policy,
notwithstanding that such loss may have been proximately caused solely or
partially by the negligence or willful misconduct of Landlord or any of
Landlord's Related Parties. If Tenant does not procure insurance as required,
Landlord may, upon advance written notice to Tenant, cause this insurance to be
issued and Tenant shall pay to Landlord the premium for such insurance within
ten (10) days of Landlord's demand, plus interest at the Default Rate until
repaid by Tenant. Tenant shall provide to Landlord a certificate of insurance
that shall provide that Landlord shall be given at least thirty (30) days' prior
written notice of any cancellation or nonrenewal of any such policy. A
certificate evidencing each such policy shall be deposited with Landlord by
Tenant on or before the Commencement Date, and a replacement certificate
evidencing each subsequent policy shall be deposited with Landlord at least
thirty (30) days prior to the expiration of the preceding such policy. All
insurance policies obtained by Tenant shall be written as primary policies
(primary over any insurance carried by Landlord), not contributing with and not
in excess of coverage which Landlord may carry, if any. Notwithstanding the
foregoing, so long as Tenant maintains a net worth of at least $100,000,000.00,
Tenant shall have the right to assume, insure or maintain a plan of self-
insurance for all or any part of the insurance required by Landlord under this
Lease.

     Section 6.5    Waiver of Subrogation Rights.  Each party hereto waives all
                    ----------------------------
rights of recovery, claims, actions or causes of actions arising in any manner
in its (the "Injured Party's") favor and against the other party for loss or
             ---------------
damage to the Injured Party's property located within or constituting a part or
all of the Project, to the extent the loss or damage: (a) is covered by the
Injured Party's insurance; or (b) would have been covered by the insurance the
Injured Party is required to carry under this Lease, whichever is greater,
regardless of the cause or origin, including the sole, contributory, partial,
joint, comparative or concurrent negligence of the other party. This waiver

                                      12
<PAGE>

also applies to each party's directors, officers, employees, shareholders,
partners, representatives and agents. The waiver set forth in this Section 6.5
                                                                   -----------
shall be in addition to, and not in substitution for, any other waivers,
indemnities or exclusions of liability set forth in this Lease.

                                 ARTICLE VII.


     Section 7.1    Default by Tenant.  The occurrence of any one or more of
                    -----------------
the following events shall constitute a default by Tenant under this Lease:


     (a)     Tenant shall fail to pay to Landlord any Rent or any other monetary
charge due from Tenant hereunder as and when due and payable;

     (b)     Tenant breaches or fails to comply with any term, provision,
condition or covenant of this Lease, other than as described in Section 7.1(a),
or with any of the Building rules and regulations now or hereafter established
to govern the operation of the Project;

     (c)     A Transfer (hereinafter defined) shall occur, without the prior
written approval of Landlord;

     (d)     The interest of Tenant under this Lease shall be levied on under
execution or other legal process;

     (e)     Any petition in bankruptcy or other insolvency proceedings shall be
filed by or against Tenant, or any petition shall be filed or other action taken
to declare Tenant a bankrupt or to delay, reduce or modify Tenant's debts or
obligations or to reorganize or modify Tenant's capital structure or
indebtedness or to appoint a trustee, receiver or liquidator of Tenant or of any
property of Tenant, or any proceeding or other action shall be commenced or
taken by any governmental authority for the dissolution or liquidation of Tenant
and, within thirty (30) days hereafter, Tenant fails to secure a discharge
thereof;

     (f)     Tenant shall become insolvent, or Tenant shall make an assignment
for the benefit of creditors, or Tenant shall make a transfer in fraud of
creditors, or a receiver or trustee shall be appointed for Tenant or any of its
properties;

     (g)     During the first twelve (12) months of the Term, Tenant shall
desert, abandon or vacate the Premises or any substantial portion thereof or
fails to operate its business in the Premises for any reason other than
destruction or condemnation of the Premises; thereafter, Tenant shall have the
right to vacate all or any part of the Premises so long as Tenant continues to
comply with all of the other terms and conditions of this Lease;

     (h)     Tenant shall do or permit to be done anything which creates a lien
upon the Premises or the Project and such lien is not removed within the time
period specified in Section 5.2 hereof.

     Section 7.2    Landlord's Remedies.  Upon occurrence of any default by
                    -------------------
Tenant under this Lease and (i) if the event of default described in Section
7.1(a) is not cured within ten (10) days after receipt by Tenant of written
notice from Landlord of such default (provided, however, Landlord shall only be
obligated to notify Tenant in writing twice during any twelve (12) month period,
thereafter, Tenant shall be in default if Tenant fails to pay any sum due under
this Lease as and when due); or (ii) the events described in Sections 7.1(b),
(d), (f) and (g) are not cured within thirty (30) days after written notice from
Landlord of such default (unless such default cannot reasonably be corrected
within said thirty (30) days in which event Tenant shall not be in default if
Tenant commences such correction within said thirty (30) days and thereafter
diligently prosecutes such correction to completion; there being no notice and
cure period for events of defaults described in Sections 7.1(c), (e) and (h)
except as otherwise set forth herein), the 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 by law or in equity or by
this Lease:

     (a)     Continue this Lease in full force and effect, and this Lease shall
continue in full force and effect as long as Landlord does not terminate this
Lease, and Landlord shall have the right to collect Rent, Additional Rent and
other charges when due.

of (i) the cost of recovering the Premises, (ii) the cost of removing and
storing Tenant's or any other occupant's property, (iii) the unpaid Rent and any
other sums accrued hereunder at the date of termination, (iv) a sum equal to the
amount, if any, by which the present value of the total Rent and other benefits
which would have accrued to Landlord under this Lease for the remainder of the
Term, if the terms of this Lease had been fully complied with by Tenant,
discounted at five percent (5%) per annum exceeds the total fair market value of
the Premises for the balance of the Term (it being the agreement of the parties
hereto that Landlord shall receive the benefit of its bargain), (v) the cost of
reletting the Premises including, without limitation, the cost of restoring the
Premises to the condition necessary to rent the Premises at the prevailing
market rental rate, normal wear and tear excepted, (vi) any increase in
insurance premiums caused by the vacancy of the Premises, (vii) the amount of
any unamortized improvements to the Premises paid for by Landlord, (viii) the
amount of any unamortized brokerage commission or other costs paid by Landlord
in connection with the leasing of the Premises and (ix) any other sum of money
or damages owed by Tenant to Landlord. In the event Landlord shall elect to
terminate this Lease, Landlord shall at once have all the rights of reentry upon
the Premises, without becoming liable for damages, or guilty of trespass.

     (c)     Terminate Tenant's right of occupancy of the Premises and reenter
and repossess the Premises by entry, forcible entry or detainer suit or
otherwise, without demand or notice of any kind to Tenant and without
terminating this Lease, without acceptance of surrender of possession of the
Premises, and without becoming liable for damages or guilty of trespass, in
which event Landlord may, but shall be under no obligation to, relet the
Premises or any part thereof for the account of Tenant (nor shall Landlord be
under any obligation to relet the Premises before Landlord relets or leases any
other portion of the Project or any other property under the ownership or
control of Landlord) for a period equal to or lesser or greater than the
remainder of the Term of the Lease on whatever terms and conditions Landlord, at
Landlord's sole discretion, deems advisable. Tenant shall be liable for and
shall pay to Landlord all Rent payable by Tenant under this Lease (plus interest
at the Default Rate provided in Section 3.1(c) of this Lease if in arrears) plus
an amount equal to (i) the cost of recovering possession of the Premises, (ii)
the cost of removing and storing any of Tenant's or any other occupant's
property left on the Premises or the Project after reentry, (iii) the cost of
decorations, repairs, changes, alterations and additions to the Premises and the
Project, (iv) the cost of any attempted reletting or reletting and the
collection of the rent accruing from such reletting, (v) the cost of any
brokerage fees or commissions payable by Landlord in connection with any
reletting or attempted reletting, (vi) any other costs incurred by Landlord in
connection with any such reletting or attempted reletting, (vii) the cost of any
increase in insurance premiums caused by the termination of possession of the
Premises, (viii) the cost of any increase in insurance premiums caused by the
termination of possession of the Premises, (ix) the amount of any unamortized
improvements to the Premises paid for by Landlord, (x) the amount of any
unamortized brokerage commissions or other costs paid by Landlord in connection
with the leasing of the Premises and (xi) any other sum of money or damages owed
by Tenant to Landlord at law., It is agreed to by Landlord and Tenant that all
the above will be reduced by any sums received by Landlord through any reletting
of the Premises; provided, however, that in no event shall Tenant be entitled to
                 --------  -------
any excess of any sums obtained by reletting over and above Rent provided in
this Lease to be paid by Tenant to Landlord. For the purpose of such reletting
Landlord is authorized to make any repairs, changes, alterations or additions in
or to the Premises that may be necessary. Landlord may file suit to recover any
sums falling due under the terms of this Section 7.2(c) from time to time, and
                                         --------------
no delivery to or recovery by Landlord of any portion due Landlord hereunder
shall be any defense in any action to recover any amount not theretofore reduced
to judgment in favor of Landlord. No reletting shall be construed as an election
on the part of Landlord to terminate this Lease unless a written notice of such
intention is given to Tenant by Landlord. Notwithstanding any such reletting
without termination, Landlord may at any time thereafter elect to terminate this
Lease for such previous default and/or exercise its rights under Section 7.2(b)
                                                                 --------------
of this Lease.

     (d)     Enter upon the Premises and do whatever Tenant is obligated to do
under the terms on this Lease; and Tenant agrees to reimburse Landlord on demand
for any expenses which Landlord may incur in effecting compliance with Tenant's
obligations under this Lease plus fifteen percent (15%) of such cost to cover
overhead plus interest at the Default Rate provided in this Lease, and Tenant
further agrees that Landlord shall not be liable for any damages resulting to
Tenant from such action. No action taken by Landlord under this Section 7.2(d)
shall relieve Tenant from any of its obligations under this Lease or from any
consequences or liabilities arising from the failure to perform such
obligations.

     (e)     Change all door locks and other security devices of Tenant at the
Premises and/or the Project, and Landlord shall not be required to provide the
new key to the Tenant except during Tenant's regular business hours, and only
upon the condition that Tenant has cured any and all defaults hereunder and in
the case where Tenant owes Rent to the Landlord, reimbursed Landlord for all
Rent and other sums due Landlord hereunder.  Landlord, on terms and conditions
satisfactory to Landlord in its sole discretion, may upon request from Tenant's
employees, enter the Premises for the purpose of retrieving therefrom personal
property of such employees, provided, Landlord shall have no obligation to do
so.

     (f)     Exercise any and all other remedies available to Landlord in this
Lease, at law or in equity.

     Section 7.3    Waiver of Duty to Relet or Mitigate. Notwithstanding
                    -----------------------------------
anything contained herein to the contrary, to the full extent permitted under
applicable law, Tenant and Landlord agree that Landlord shall have no duty to
relet the Premises or otherwise mitigate damages under this Lease and Tenant
hereby releases Landlord from any and all duty to relet the Premises or
otherwise mitigate damages. Tenant agrees that Landlord shall not be liable, nor
shall Tenant's obligations hereunder be diminished, because of Landlord's
failure to relet the Premises or collect rent due with respect to such
reletting. Furthermore, Tenant hereby waives any and all rights to plead such
failure of Landlord to mitigate damages as an affirmative defense in any
proceeding based on any Default by Tenant under this Lease. In the event, and
only in the event, that (despite such waiver and contrary to the intent of the
parties hereunder) applicable law requires Landlord to attempt to mitigate
damages, Landlord and Tenant agree that any such duty to mitigate shall be
satisfied and Landlord shall be deemed to have used objectively reasonable
efforts to fill the Premises by doing the following: (a) posting a "For Lease"
sign on the Premises; (b) advising Landlord's leasing agent of the availability
of the Premises; and (c) advising at least five (5) national outside commercial
brokerage entities of the availability of the Premises; provided, however, that
                                                        --------  -------
Landlord shall not be obligated to relet the Premises before leasing any other
unoccupied portions of the Project and any other property under the ownership or
control of Landlord. If Landlord receives any payments from the reletting of the
Premises and is required to mitigate damages (despite the intent of the parties
hereunder), any such payment shall first be applied to any costs or expenses
incurred by Landlord as a result of Tenant's Default under this Lease.

     Section 7.4    Reentry. If Tenant fails to allow Landlord to reenter and
                    -------
repossess the Premises, Landlord shall have full and free license to enter into
and upon the Premises with process of law for the purpose of repossessing the
Premises, expelling or removing Tenant and any others who may be occupying or
within the

                                      14
<PAGE>

Premises, removing any and all property therefrom and changing all door locks of
the Premises. Landlord may take these actions without being deemed in any manner
guilty of trespass, eviction or forcible entry or detainer, without accepting
surrender of possession of the Premises by Tenant, and without incurring any
liability for any damage resulting therefrom, including without limitation any
liability arising under applicable state law and without relinquishing
Landlord's right to Rent or any other right given to Landlord hereunder or by
operation of law or in equity.

     Section 7.5    Rights of Landlord in Bankruptcy. Nothing contained in this
                    --------------------------------
Lease shall limit or prejudice the right of Landlord to prove for and obtain in
proceedings for bankruptcy or insolvency, by reason of the expiration or
termination of this Lease or the termination of Tenant's right of occupancy, an
amount equal to the maximum allowed by any statute or rule of law in effect at
the time when, and governing the proceedings in which, the damages are to be
proved, whether or not the amount be greater, equal to, or less than the amount
of the loss or damages referred to in this Section 7.5. In the event that under
applicable law, the trustee in bankruptcy or Tenant has the right to affirm this
Lease and continue to perform the obligations of Tenant hereunder, such trustee
or Tenant shall, in such time period as may be permitted by the bankruptcy court
having jurisdiction, cure all defaults of Tenant hereunder outstanding as of the
date of the affirmance of this Lease and provide to Landlord such adequate
assurances as may be necessary to ensure Landlord of the continued performance
of Tenant's obligations under this Lease.

     Section 7.6    Waiver of Certain Rights. To the extent permitted by
                    ------------------------
applicable law, Tenant hereby expressly waives any and all rights Tenant may
have under applicable state law to its right to redeem the Premises or otherwise
recover possession of the Premises after a termination of this Lease. Tenant
hereby waives any and all liens (whether statutory, contractual or
constitutional) it may have or acquire as a result of a breach by Landlord under
this Lease. Tenant also waives and releases any statutory lien and offset rights
it may have against Landlord, including without limitation the rights conferred
upon applicable state law.

     Section 7.7    Non-Waiver. Failure on the part of Landlord to complain of
                    ----------
any action or nonaction on the part of Tenant, no matter how long the same may
continue, shall not be deemed to be a waiver by Landlord of any of its rights
under this Lease. Further, it is covenanted and agreed that no waiver at any
time of any of the provisions hereof by Landlord shall be construed as a waiver
of any of the other provisions hereof and that a waiver at any time of any of
the provisions hereof shall not be construed as a waiver at any subsequent time
of the same provisions. The consent or approval by Landlord to or of any action
by Tenant requiring Landlord's consent or approval shall not be deemed to waive
or render unnecessary Landlord's consent or approval to or of any subsequent
similar act by Tenant.

     Section 7.8    Holding Over. In the event Tenant remains in possession of
                    ------------
the Premises after the expiration or termination of this Lease without the
execution of a new lease, then Tenant, at Landlord's option, shall be deemed to
be occupying the Premises as a tenant at will at a base rental equal to one
hundred twenty five percent (125%) for the first thirty (30) days, then one
hundred fifty percent (150%) thereafter of the then applicable Base Rent, and
shall otherwise remain subject to all the conditions, provisions and obligations
of this Lease insofar as the same are applicable to a tenancy at will, including
without limitation the payment of all other Rent; provided, however, nothing
                                                  --------  -------
contained herein shall require Landlord to give Tenant more than thirty (30)
days prior written notice to terminate Tenant's tenancy-at-will. No holding over
by Tenant after the expiration or termination of this Lease shall be construed
to extend or renew the Term or in any other manner be construed as permission by
Landlord to hold over. Tenant shall indemnify Landlord against all claims for
damages by any other tenant to whom Landlord may have leased all or any part of
the Premises effective upon the termination or expiration of this Lease, and for
all other losses, costs and expenses, including reasonable attorneys' fees,
incurred by reason of such holding over.

     Section 7.9    Abandonment of Personal Property. Any personal property
                    --------------------------------
left in the Premises or any personal property of Tenant left about the Project
at the expiration or termination of this Lease, the termination of Tenant's
right to occupy the Premises or the abandonment, desertion or vacating of the
Premises by Tenant, shall be deemed abandoned by Tenant and may, at the option
of Landlord, be immediately removed from the Premises or such other space by
Landlord and stored by Landlord at the full risk, cost and expense of Tenant.
Landlord shall in no event be responsible for the value, preservation or
safekeeping thereof. In the event Tenant does not reclaim any such personal
property and pay all costs for any storage and moving thereof within thirty (30)
days after the expiration or termination of this Lease, the termination of
Tenant's right to occupy the Premises or the abandonment, desertion or vacating
of the Premises by Tenant, Landlord may dispose of such personal property in any
way that it deems proper. If Landlord shall sell any such personal property, it
shall be entitled to retain from the proceeds the amount of any Rent or other
expenses due Landlord, together with the cost of storage and moving and the
expense of the sale. Notwithstanding anything contained herein to the contrary,
in addition to the rights provided herein with respect to any such property,
Landlord shall have the option of exercising any of its other rights or remedies
provided in the Lease or exercising any rights or remedies available to Landlord
at law or in equity.

     Section 7.10   Quiet Enjoyment. So long as there is no continuing event
                    ---------------
of default by Tenant as defined in Section 7.1, Landlord covenants and agrees
that Tenant shall peacefully and quietly have, hold and enjoy the Premises for
the Term without hindrance by Landlord or any person claiming through or under
Landlord.


                                 ARTICLE VIII.


     Section 8.1    Transfers. Except in strict accordance with the provisions
                    ---------
of this Article VIII, Tenant shall not, by operation of law or otherwise, (a)
assign, transfer, mortgage, pledge, hypothecate or otherwise encumber this

                                      15
<PAGE>

Lease, the Premises or any part of or interest in this Lease or the Premises,
(b) grant any concession or license within the Premises, (c) sublet all or any
part of the Premises or any right or privilege appurtenant to the Premises, or
(d) permit any other party to occupy or use all or any part of the Premises
(collectively, a "Transfer"), without the prior written consent of Landlord
which consent shall not be unreasonably withheld, delayed or conditioned. This
prohibition against a Transfer includes, without limitation, (i) any subletting
or assignment which would otherwise occur by operation of law, merger,
consolidation, reorganization, transfer or other change of Tenant's corporate or
proprietary structure, except in accordance with this Section 8.1; (ii) an
assignment or subletting to or by a receiver or trustee in any Federal or State
bankruptcy, insolvency, or other proceedings; (iii) the sale, assignment or
transfer of all or substantially all of the assets of Tenant, with or without
specific assignment of Lease; (iv) the change in control in a partnership; or
(v) conversion of Tenant to a limited liability entity. If Tenant converts to a
limited liability entity without obtaining the prior written consent of
Landlord: (i) the conversion shall be null and void for purposes of the Lease,
including the determination of all obligations and liabilities of Tenant and its
partners to Landlord; (ii) all partners of Tenant immediately prior to its
conversion to a limited liability shall be fully liable, jointly and severally,
for obligations of Tenant accruing under this Lease pre-conversion and post-
conversion, and all members and other equity holders in Tenant post-conversion
shall be fully liable for all obligations and liabilities of Tenant accruing
under the Lease after the date such members and other equity holders are
admitted to the limited liability entity as if such person or entity had become
a general partner in a partnership; and (iii) Landlord shall have the option of
declaring Tenant in Default under this Lease. If Tenant requests Landlord's
consent to any Transfer, then Tenant shall provide Landlord with a written
description of all terms and conditions of the proposed Transfer, copies of the
proposed documentation, and the following information about the proposed
transferee: name and address; reasonably satisfactory information about its
business and business history; its proposed use of the Premises; a copy of the
proposed sublease or assignment agreement; banking, financial and other credit
information; and general references sufficient to enable Landlord to determine
the proposed transferee's creditworthiness and character. Landlord's consent to
a Transfer shall not release Tenant from performing its obligations under this
Lease, but rather Tenant's transferee shall assume all of Tenant's obligations
under this Lease in a writing satisfactory to Landlord, and Tenant and its
transferee shall be jointly and severally liable therefor. Landlord's consent to
any Transfer shall not waive Landlord's rights as to any subsequent Transfer. If
the aggregate rental, bonus or other consideration paid by a transferee for any
such space exceeds the sum of (y) Tenant's Rent to be paid to Landlord for such
space during such period less (z) Tenant's costs and expenses actually incurred
in connection with such Transfer, including reasonable brokerage fees,
reasonable costs of finishing or renovating the space affected and reasonable
cash rental concessions, which costs and expenses are to be amortized over the
term of the Transfer (a "Profit"), then fifty percent (50%) of such Profit shall
be paid to Landlord over the term after such amount is earned by Tenant
(notwithstanding the foregoing, Tenant shall be entitled to retain one hundred
percent (100%) of any Profit with respect to the first thirty thousand (30,000)
rentable square feet of Premises subleased by Tenant). Such Profit in the case
of a sublease shall be calculated and adjusted (if necessary) on a Lease Year
(or partial Lease Year) basis, and there shall be no cumulative adjustment for
the Term. Landlord shall have the right to audit Tenant's books and records
relating to the Transfer. Tenant authorizes its transferees to make payments of
rent and any other sums due and payable, directly to Landlord upon receipt of
notice from Landlord to do so. Any attempted Transfer by Tenant in violation of
the terms and covenants of this Article VIII shall be void and shall constitute
a Default by Tenant under this Lease. In the event that Tenant requests that
Landlord consider a sublease or assignment hereunder, Tenant shall pay
Landlord's reasonable fees including Landlord's reasonable attorney's fees, not
to exceed Five Hundred and 00/100 Dollars ($500.00) per transaction, incurred in
connection with the consideration of such request.

     Section 8.2    Permitted Transfers. Notwithstanding any provision to the
                    -------------------
contrary, Tenant may assign this Lease or sublet the Premises without Landlord's
consent (i) to any corporation or affiliate or any other entity that controls,
is controlled by or is under common control with Tenant; (ii) to any corporation
or other entity resulting from a merger, acquisition, consolidation or
reorganization of or with Tenant; (iii) in connection with the sale of all or
substantially all of the assets of Tenant (collectively, a "Permitted
Transferee"), so long as Tenant provides evidence to Landlord in writing that
such assignment or sublease complies with the criteria set forth in (i), (ii) or
(iii) above and provided such assignee, subtenant or successor-in-interest
expressly assumes Tenants' obligations and liabilities hereunder. No such
assignment, sublease or transfer, however, shall release Tenant from any
covenant, liability or obligation under this Lease unless agreed to by Landlord
in writing.

     Section 8.3    Assignment by Landlord. Landlord shall have the right at
                    ----------------------
any time to sell, transfer or assign, in whole or in part, by operation of law
or otherwise, its rights, benefits, privileges, duties, obligations or interests
in this Lease or in the Premises, the Building, the Land, the Project and all
other property referred to herein, without the prior consent of Tenant, and such
sale, transfer or assignment shall be binding on Tenant. After such sale,
transfer or assignment, Tenant shall attorn to such purchaser, transferee or
assignee, and Landlord shall be released from all liability and obligations
under this Lease accruing after the effective date of such sale, transfer or
assignment.

     Section 8.4    Limitation of Landlord's Liability. Any provisions of this
                    ----------------------------------
Lease to the contrary notwithstanding, Tenant hereby agrees that no personal,
partnership or corporate liability of any kind or character (including, without
limitation, the payment of any judgment) whatsoever now attaches or at any time
hereafter under any condition shall attach to Landlord or any of Landlord's
Related Parties or any mortgagee for payment of any amounts payable under this
Lease or for the performance of any obligation under this Lease. The exclusive
remedies of Tenant for the failure of Landlord to perform any of its obligations
under this Lease shall be to proceed against the interest of Landlord in and to
the Project. Further, in no event shall Landlord be liable to Tenant, or any
interest of Landlord in the Project be subject to execution by Tenant, for any
indirect, special, consequential or punitive damages. In no event shall Tenant
be liable to Landlord for any indirect, special, consequential (except for
Tenant's indemnity of Landlord set forth in Section 7.8 hereof) or punitive
damages.

                                  ARTICLE IX.


     Section 9.1    Subordination. Landlord represents and warrants to Tenant
                    -------------
that the Project is not currently subject to any mortgage, deed of trust, ground
lease or similar encumbrance. This Lease shall be subject and subordinated at
all times to (a) all ground or underlying leases which may hereinafter be
executed affecting the Project, and (b) the lien or liens of all mortgages and
deeds of trust in any amount or amounts whatsoever hereafter placed on the
Project or Landlord's interest or estate therein or on or against such ground or
underlying leases and to all renewals, modifications, consolidations,
replacements and extensions thereof and to each advance made or hereafter to be
made thereunder. Tenant shall execute and deliver upon demand any instruments,
releases or other documents requested by Landlord, any lessor or mortgagee for
the purpose of subjecting and subordinating this Lease to such ground leases,
mortgages or deeds of trust. Tenant shall attorn to any party succeeding to
Landlord's interest in the Premises, whether by purchase, foreclosure, deed in
lieu of foreclosure, power of sale, termination of lease or otherwise, only upon
such party's request and at such party's sole discretion but not otherwise.
Notwithstanding such attornment, Tenant agrees that any such successor in
interest shall not be (a) liable for any act or omission of, or subject to any
rights of setoff, claims or defenses otherwise assertable by Tenant against, any
prior owner of the Project (including without limitation, Landlord), (b) bound
by any rents paid more than one (1) month in advance to any prior owner, and (c)
if such successor is a mortgagee or a ground lessor whose address has been
previously given to Tenant, bound by any modification, amendment, extension or
cancellation of the Lease not consented to in writing by such mortgagee or
ground lessor. Tenant shall execute all such agreements confirming such
attornment as such party may reasonably request. Tenant shall not seek to
enforce any remedy it may have for any default on the part of Landlord without
first giving written notice by certified mail, return receipt requested,
specifying the default in reasonable detail, to any mortgagee or lessor under a
lien instrument or lease covering the Premises whose address has been given to
Tenant, and affording such mortgagee or lessor a reasonable opportunity to
perform Landlord's obligations hereunder. Notwithstanding the generality of the
foregoing, any mortgagee or ground lessor may at any time subordinate any such
deeds of trust, mortgages, other security instruments or ground leases to this
Lease on such terms and conditions as such mortgagee or ground lessor may deem
appropriate.

     Section 9.2    Estoppel Certificate or Three-Party Agreement. Tenant
                    ---------------------------------------------
agrees within fifteen (15) business days following request by Landlord (a) to
execute, acknowledge and deliver to Landlord and any other persons specified by
Landlord, a certificate or three-party agreement among Landlord, Tenant and/or
any third party dealing with Landlord, certifying (i) that this Lease is
unmodified and in full force and effect, or, if modified, stating the nature of
such modification (ii) the date to which the Rent and other charges are paid in
advance, if any, (iii) that there are not, to Tenant's knowledge, any uncured
defaults on the part of Landlord hereunder, or so specifying such defaults, if
any, as are claimed and/or (iv) any other matters as such third party may
reasonably require in connection with the business dealings of Landlord and/or
such third party. Tenant's failure to deliver such certificate or three-party
agreement within such fifteen (15) business day period shall be conclusive upon
Tenant (x) that this Lease is in full force and effect without modification
except as may be represented by Landlord, (y) that to Tenant's knowledge there
are no uncured defaults in Landlord's performance, and (z) that no Rent has been
paid in advance except as set forth in this Lease.

     Section 9.3    Notices. Any notice, request, approval, consent or other
                    -------
communication required or contemplated by this Lease must be in writing, unless
otherwise in this Lease expressly provided, and may be given or be served by
depositing the same in the United States Postal Service, postpaid and certified
and addressed to the party to be notified, with return receipt requested, or by
delivering the same in person to such party (or, in case of a corporate party,
to an officer of such party), or by prepaid telegram or express overnight mail
service, when appropriate, addressed to the party to be notified. Notice
deposited in the mail in the manner hereinabove described shall be effective
from and after three (3) days (exclusive of Saturdays, Sundays and postal
holidays) after such deposit. Notice given in any other manner shall be
effective only if and when delivered to the party to be notified or at such
party's address for purposes of notice as set forth herein. For purposes of
notice the addresses of the parties shall, until changed as herein provided, be
as provided on the first page of this Lease; provided, that any notices sent to
Tenant will only be effective if copies thereof are simultaneously sent to IKON
Office Solutions, Inc. 70 Valley Stream Parkway, Malvern PA 19355, Attn: Real
estate Department and 810 Gears Road, Houston, Texas, Attn: Facilities Manager,
and provided, that any notices sent to Landlord will only be effective if copies
thereof are simultaneously sent to Brookdale Investors Three, L.P., 3343

     Section 10.1   Rights and Remedies Cumulative. The rights and remedies of
                    ------------------------------
Landlord and Tenant under this Lease shall be nonexclusive and each right or
remedy shall be in addition to and cumulative of all other rights and remedies
available to Landlord and Tenant under this Lease or at law or in equity.
Pursuit of any right or remedy shall not preclude pursuit of any other rights or
remedies provided in this Lease or at law or in equity, nor shall pursuit of any
right or remedy constitute a forfeiture or waiver of any Rent due to Landlord or
services to be provided to Tenant or of any damages accruing to Landlord or
Tenant by reason of the violation of any of the terms of this Lease.

     Section 10.2   Legal Interpretation. This Lease and the rights and
                    --------------------
obligations of the parties hereto shall be interpreted, construed and enforced
in accordance with the laws of the state in which the Building is located and
the United States. The determination that one or more provisions of this Lease
is invalid, void, illegal or unenforceable shall not affect or invalidate any
other provision of this Lease, and this Lease shall be construed as if such
invalid, illegal or unenforceable provision had never been contained in this
Lease, and, so far as is reasonable and possible, effect shall be given to the
intent manifested by the portion held invalid or inoperative. All obligations of
either party hereunder not fully performed as of the expiration or termination
of the Term of this Lease shall survive the expiration or termination of the
Term of this Lease and shall be fully enforceable in accordance with those
provisions pertaining thereto. Article and section titles and captions appearing
in this Lease are for convenient reference only and shall not be used to
interpret or limit the meaning of any provision of this Lease. No custom or
practice which may evolve between the parties in the administration of the terms
of this Lease shall waive or diminish the right of Landlord to insist upon the
performance by Tenant in strict accordance with the terms of this Lease. This
Lease is for the sole benefit of Landlord and Tenant, and, without the express
written consent thereto, no third party shall be deemed a third party
beneficiary hereof. Tenant agrees that this Lease supersedes and cancels any and
all previous statements, negotiations, arrangements, brochures, agreements and
understandings, if any, between Landlord and Tenant with respect to the subject
matter of this Lease or the Premises and that this Lease, including written
extrinsic documents referred to herein, is the entire agreement of the parties,
and that there are no representations, understandings, stipulations, agreements,
warranties or promises (express or implied, oral or written) between Landlord
and Tenant with respect to the subject matter of this Lease or the Premises. It
is likewise agreed that this Lease may not be altered, amended, changed or
extended except by an instrument in writing signed by both Landlord and Tenant.
The terms and provisions of this Lease shall not be construed against or in
favor of a party hereto merely because such party is the "Landlord" or the
"Tenant" hereunder or because such party or its counsel is the draftsman of this
Lease. All references to days in this Lease and any Exhibits or Addendums hereto
mean calendar days, not working or business days, unless otherwise stated.

     Section 10.3   Authority. Both Tenant and the person executing this Lease
                    ---------
on behalf of Tenant warrant and represent unto Landlord that (a) Tenant is a
duly organized and validly existing legal entity, in good standing and qualified
to do business in the state in which the Building is located, with no
proceedings pending or contemplated for its dissolution or reorganization,
voluntary or involuntary, (b) Tenant has full right, power and authority to
execute, deliver and perform this Lease, (c) the person executing this Lease on
behalf of Tenant is authorized to do so, (d) upon execution of this Lease by
Tenant, this Lease shall constitute a valid and legally binding obligation of
Tenant, and (e) upon request of Landlord, such person will deliver to Landlord
satisfactory evidence of the matters set forth in this Section. Both Landlord
and the person executing this Lease on behalf of Landlord warrant and represent
unto Tenant that (a) Landlord is a duly organized and validly existing legal
entity, in good standing and qualified to do business in the state in which the
