      The foregoing schedule is based upon an assumed Commencement Date of
      January 1, 2002. If the actual Commencement Date is after January 1, 2002,
      the expiration date will be extended by the number of days after January
      1, 2002 until the Commencement Date (except that if the expiration date
      would not be the last day of a calendar month the term shall extend until
      the last day of the calendar month). If the actual Commencement Date is
      before January 1, 2002, an appropriate adjustment shall be made for the
      period prior to January 1, 2002, based upon the per square foot per year
      rental rate for the Premises of $15.00.

      F.  RENTABLE AREA OF THE BUILDING:  264,769 Square Feet

      G.  RENTABLE AREA OF THE PREMISES:  2,897 Square Feet

      H.  TENANT'S PROPORTIONATE SHARE:   One and 09/100 percent (1.09%) (the
                                          percentage calculated by dividing the
                                          Rentable Area of the Premises by the
                                          Rentable Area of the Building).
                                          Tenant's Proportionate Share shall be
                                          modified from time to time in the
                                          event the final design of the Building
                                          is hereafter modified such that the
                                          Rentable Area of the Premises or the
                                          Rentable Area of the Building, or
                                          both, differs from the square footage
                                          set forth herein. In such event,
                                          Landlord shall recalculate Tenant's
                                          Proportionate Share based upon such
                                          modification or change for the
                                          remainder of the Term and shall notify
                                          Tenant of such recomputed Tenant's
                                          Proportionate Share.

      I.  TARGET COMMENCEMENT DATE:       January 1, 2002

      J.  LEASE TERM:                     The period of time commencing on the
                                          Commencement Date and expiring sixty
                                          (60) months after the Commencement
                                          Date (except that if the expiration
                                          date would not be the last day of a
                                          calendar month the term shall extend
                                          until the last day of the calendar
                                          month), unless sooner terminated or
                                          extended as may be herein provided.

      K.  SECURITY DEPOSIT:               $25,000.00

      N.  EXHIBITS:           A.      Plan of Premises
                              B.      Rules and Regulations
                              C.      Construction Rider

1.02  EFFECT OF REFERENCE TO BASIC TERMS. Each reference in this Lease to any of
the Basic Terms contained in Paragraph 1.01 shall be construed to incorporate
into such reference the definition thereof as set forth in Paragraph 1.01.

ARTICLE 2 - QUIET ENJOYMENT

2.01  QUIET ENJOYMENT. Landlord covenants that Tenant, on paying the Rent herein
provided and keeping, performing and observing each and every term, covenant,
and condition herein required of Tenant, shall peaceably and quietly hold and
enjoy the Premises without hindrance or molestation by Landlord for the Lease
Term, subject to the terms of this Lease and any encumbrances, easements,
rights, covenants, conditions and restrictions of record existing as of the date
of this Lease or placed on the Building hereafter together with the
non-exclusive right to use, in common with others, the Common Areas (as defined
in Article 9).

ARTICLE 3 - GRANT, DELIVERY AND TERM

3.01  GRANT OF PREMISES. In consideration of the rents, terms, covenants, and
conditions hereinafter provided to be paid, kept, performed and observed,
Landlord hereby leases to Tenant and Tenant hereby leases from Landlord the
Premises.

3.02  CONDITIONS OF GRANT. Tenant shall have and hold the Premises for and
during the Lease Term, subject to the payment of the Rent and to the full and
timely performance by Tenant of all of the covenants and conditions hereinafter
set forth.

3.03  DELIVERY AND ACCEPTANCE OF PREMISES. Landlord shall make a good faith
effort to Substantially Complete the Premises ("Substantially Complete" having
the meaning as defined in Exhibit C, Construction Rider) by the Target
Commencement Date. However the actual commencement date shall be the
"Commencement Date" defined in Exhibit C. Promptly following the Commencement
Date, Landlord and Tenant shall execute and deliver to one another a
confirmation of the Commencement Date. No promise of Landlord to alter, remodel,
decorate, clean or improve the Premises or the Building and no representation
respecting the condition of the Premises or the Building has been made by
Landlord to Tenant, unless the same is contained herein or in the Construction
Rider. Tenant's taking possession of the Premises or any part thereof shall be
conclusive evidence against Tenant that the portion of the Premises taken
possession of was then in good order and satisfactory condition.

3.04  DELAY OF POSSESSION. If Landlord fails to give possession of the Premises
on the Target Commencement Date for any reason, Landlord shall not be subject to
any liability whatsoever for

                                        3
<Page>

such failure. Under such circumstances, neither the Lease Term nor Tenant's
obligation to pay Rent shall commence until the Commencement Date. If such a
delay is caused by a Tenant Delay (as defined in Exhibit C), then Tenant's
obligation to pay Rent shall commence on the date that the Premises would have
been Substantially Complete but for such Tenant Delay. No failure to give
possession on the Target Commencement Date shall affect or impair the validity
of this Lease or the obligations of Tenant, except as set forth above in this
Paragraph 3.04. Tenant agrees to accept the suspension or abatement of Rent
noted above in full settlement of all claims which Tenant might otherwise have
due to such delay.

3.05  SUBSTITUTE PREMISES. At any time hereafter, Landlord may substitute for
the Premises other premises (herein referred to as the "New Premises") provided:

      A.   The New Premises shall be located on a floor not lower than the ninth
      floor in the Building and be similar to the Premises in area;

      B.   Landlord shall pay the reasonable out-of-pocket expenses of Tenant
      for moving from the Premises to the New Premises, for improving the New
      Premises so that they are substantially similar to the Premises (including
      wiring and kitchen), and for the relocation of Tenant's office equipment
      including, but not limited to, telephone and computer systems; provided,
      however, instead of paying the expenses of moving Tenant's property,
      Landlord may elect to move Tenant's property under the reasonable
      direction of Tenant;

      C.   Such move shall be made during evenings, weekends, or otherwise so as
      to incur the least inconvenience to Tenant as reasonably possible;

      D.   Landlord shall give Tenant at least ninety (90) days notice before
      making such a substitution. The substitution date may be changed from time
      to time thereafter upon at least seven (7) days further notice by
      Landlord. On the actual date of relocation, Tenant shall vacate the
      Premises as if the term of the Lease expired on such date and comply with
      the requirements of this Lease imposed on Tenant upon the expiration of
      the Lease. If Landlord shall exercise its right hereunder, the New
      Premises shall thereafter be deemed for the purposes of the Lease to be
      the Premises; and

      E.   Tenant shall not be entitled to any compensation for any
      inconvenience or interference with Tenant's business, nor to any abatement
      or reduction in Rent, nor shall Tenant's obligations under this Lease be
      otherwise affected as a result of the substitution. However, Base Rent and
      Additional Rent shall be adjusted on a per square foot basis to reflect
      the rentable square footage of the New Premises as compared to the
      Premises. Such adjustment shall be set forth in writing by Landlord and
      considered an amendment to this Lease. Tenant agrees to cooperate with
      Landlord so as to facilitate the prompt completion by Landlord of its
      obligations under this Paragraph 3.06. Without limiting the generality of
      the preceding sentence, Tenant agrees to promptly provide to Landlord such
      approvals, instructions, plans, specifications or other information as may
      be reasonably requested by Landlord.

ARTICLE 4 - SURRENDER AND HOLDING OVER

4.01  SURRENDER. Upon the expiration of the term of the Lease or upon the
termination of Tenant's right of possession, whether by lapse of time or at the
option of Landlord as herein provided, Tenant shall promptly surrender the
Premises to Landlord in good order, repair and broom clean condition, ordinary
wear and casualty damage excepted. Prior thereto, Tenant shall remove its office
furniture, trade fixtures, office equipment and all other items of personal
property on the Premises not belonging to Landlord, including all cabling and
wiring installed in the Premises and/or the Building by or for the benefit of
Tenant. Tenant shall pay to Landlord upon demand the cost of repairing any
damage to the Premises and the Building caused by such removal. If Tenant shall
fail or refuse to remove any such property from the Premises, Tenant shall be
conclusively presumed to have abandoned the same, and title thereto shall
thereupon pass to Landlord without any cost by set-off, credit, allowance or
otherwise, and Landlord may at its option, accept the title to such property,
and, whether or not Landlord accepts such title, Landlord may at Tenant's
expense: (i) remove the same or any part in any manner that Landlord shall
choose, repairing any damage to the Premises caused by such removal; and
(ii) store or otherwise dispose of the same without incurring liability to
Tenant or any other person. If Landlord incurs any storage or other costs by
reason of Tenant's failure to remove any property which Tenant is obligated to
remove under this paragraph, Tenant upon demand shall pay to Landlord the amount
of costs so incurred.

4.02  HOLDOVER. If Tenant shall not immediately surrender the Premises or any
part thereof on the termination of the term of the Lease or of Tenant's right of
possession, whether by lapse of time or otherwise, as provided herein, Tenant
shall be deemed a tenant only by the month at 150% of the Base Rent and
Additional Rent in effect during the last month of the term of the Lease for
each month or part thereof during which Tenant shall retain possession of the
Premises or any part thereof thereafter. In addition, Tenant shall also pay all
damages, consequential and direct, if any, incurred by Landlord on account of
such holding over. Nevertheless, neither the provisions of this paragraph, the
acceptance of any Rent, nor any other act in apparent affirmance of tenancy
(other than a written waiver) shall be held as a waiver by Landlord of any right
of re-entry or any other rights or remedies of Landlord provided herein or at
law or equity.

ARTICLE 5 - SECURITY DEPOSIT

5.01  SECURITY DEPOSIT. Tenant herewith deposits with Landlord the Security
Deposit as security for the prompt, full, and faithful performance by Tenant of
every term, covenant and condition of this Lease.

      A.   If Tenant fails to perform any of its obligations hereunder, Landlord
      may use, apply or retain the whole or any part of the Security Deposit as
      damages for Tenant's default under Article 20, or for the payment of
      (i) any Rent or other sums of money which Tenant may not have paid when
      due, (ii) any sum expended by Landlord on Tenant's behalf in accordance
      with the provisions of this Lease, or (iii) any sum which Landlord may
      expend or be required to expend by reason of Tenant's default, including,
      without limitation, any damage or

                                        5
<Page>

      deficiency in or from the reletting of the Premises as provided in Article
      20. The use, application or retention of the Security Deposit, or any
      portion thereof, by Landlord shall not prevent Landlord from exercising
      any other right or remedy provided by this Lease or by law (it being
      intended that Landlord shall not first be required to proceed against or
      use the Security Deposit) and shall not operate as a limitation on any
      recovery to which Landlord may otherwise be entitled. If any portion of
      the Security Deposit is used, applied or retained by Landlord for the
      purposes set forth herein, Tenant agrees, within ten (10) days after the
      written demand therefor is made by Landlord, to deposit cash with Landlord
      in an amount sufficient to restore the Security Deposit to its amount
      prior to such use or application.

      B.   If Tenant shall fully and faithfully comply with all of the
      provisions of this Lease, the Security Deposit, or any balance thereof,
      shall be returned to Tenant, with interest at the rate of four percent
      (4%) per annum, after the last to occur of the expiration of the Term or
      upon any later date after which Tenant has properly vacated the Premises.
      In the absence of evidence satisfactory to Landlord of any permitted
      assignment of the right to receive the Security Deposit, or of the
      remaining balance thereof, Landlord may return the same to the original
      Tenant, regardless of one or more assignments of Tenant's interest in the
      Lease or the Security Deposit. In such event, upon the return of the
      Security Deposit or the remaining balance thereof to the original Tenant,
      Landlord shall be completely relieved of liability under this Article 5 or
      otherwise with respect to the Security Deposit.

      C.   Tenant acknowledges that Landlord has the right to transfer or
      mortgage its interest in the Building and in this Lease, and Tenant agrees
      that in the event of any such transfer or mortgage, Landlord shall have
      the right to transfer or assign the Security Deposit to the transferee or
      mortgagee. Upon written acknowledgement of transferee's or mortgagee's
      receipt of such Security Deposit, Landlord shall thereby be released by
      Tenant from all liability or obligation for the return of such Security
      Deposit and Tenant shall look solely to such transferee or mortgagee for
      the return of such Security Deposit.

      D.   The Security Deposit shall not be mortgaged, assigned, or encumbered
      in any manner whatsoever by Tenant without the prior written consent of
      Landlord.

ARTICLE 6 - RENT

6.01  BASE RENT. Tenant covenants to pay to Landlord, without notice, deduction,
set-off or abatement of any kind, the Base Rent in lawful money of the United
States in consecutive monthly installments in advance commencing on the
Commencement Date and thereafter on or before the first day of each month during
the term of the Lease. Base Rent, Additional Rent defined below, and all other
amounts due from Tenant under this Lease shall collectively be referred to as
"Rent". Rent shall be payable to Landlord at Landlord's address shown at
Paragraph 1.01 or such other place as Landlord may designate from time to time
in writing. Anything to the contrary contained in this Lease notwithstanding, if
the Commencement Date is other than the first day of a calendar month, the Base
Rent and Additional Rent for such month shall be prorated on a per diem basis
and the prorated Rent for such month, as well as the first full calendar month's
Rent, shall be paid on or

                                        6
<Page>

before the first day of the first full calendar month of the term of the Lease.
The obligation to pay Rent hereunder is independent of each and every other
term, covenant, and condition contained in this Lease. It is the practice, but
not the obligation, of Landlord to submit to Tenant a statement for Rent due
under the terms of this Lease. However, if Landlord fails to deliver such
statement or discontinues such practice for any reason, it shall not be deemed
or construed to relieve Tenant of the obligation to pay Rent in the amounts,
manner and time required hereunder.

6.02  ADDITIONAL RENT. In addition to paying the Base Rent specified in
Paragraph 6.01 hereof, Tenant shall pay as "Additional Rent" the amounts
determined as hereinafter set forth, without setoff, deduction, notice or offset
of any kind. Additional Rent for each calendar year shall be that sum which is
the product of Tenant's Proportionate Share multiplied by each component of
Basic Costs (as defined below) incurred in each calendar year. Except as
otherwise noted herein, Tenant shall pay Landlord the Additional Rent in the
same manner, time and place as the Base Rent, on or before the first day of each
calendar month during the term of the Lease. Tenant's obligation to pay
Additional Rent accruing prior to expiration or termination of the term of the
Lease shall survive the expiration or termination of the term of the Lease.

6.03  BASIC COSTS. "Basic Costs" shall mean Taxes and Operating Expenses,
including adjustments provided for herein if any, determined in accordance with
generally accepted accounting and management principles consistently applied
unless otherwise noted herein.

6.04  TAXES. "Taxes" shall mean the following described taxes or assessments
payable during a calendar year by or on behalf of Landlord, whether imposed,
levied, or assessed pursuant to provisions now or at anytime hereafter in
effect, and regardless of the period of time for or to which such Taxes apply:
(i) all federal, state, and local government taxes, assessments, and charges,
general or special, ordinary or extraordinary, imposed, levied, or assessed with
respect to the Building, exclusive of interest and penalties; (ii) ad valorem
taxes assessed or imposed upon personal property owned by Landlord or its agents
and used in the management, operation, maintenance or repair of the Building;
(iii) transit taxes; (iv) occupational taxes or excise taxes levied on rentals
derived from the operation of the Building or the privilege of leasing property;
(v) all taxes, assessments, or charges of any kind imposed, levied, or assessed
on account of Rent hereunder or of Landlord's interest under this Lease; (vi)
any taxes which shall be levied to supplement, in addition to or in lieu of any
item described in (i), (ii), (iii), (iv), or (v) above; and (vii) the expense of
protesting, negotiating or contesting the amount or validity of any such taxes,
charges or assessments, including, but not limited to, reasonable attorney's
fees and court costs, whether or not any reduction or limitation is obtained.
Taxes shall not include any federal, state, or local net income, franchise,
capital stock, inheritance or estate taxes payable by Landlord, except to the
extent such taxes are in lieu of or a substitute for any of the taxes,
assessments and charges previously described herein. The amount of any refund of
Taxes received by Landlord shall be credited against Taxes for the calendar year
in which such refund is received. In determining the amount of Taxes for any
calendar year, the amount of special assessments to be included shall be limited
to the amount of the installments (plus any interest payable thereon) of such
special assessment required to be paid during such calendar year as if Landlord
had elected to have such special assessment paid over the maximum period of time
permitted by law. If the Building is not assessed as fully improved for any
calendar year or part thereof, Landlord may make an adjustment to the amount of
Taxes for each such calendar year to

                                        7
<Page>

reflect the amount of Taxes which would have been assessed if the Building had
been assessed as fully improved, and the amount of any such adjustment shall be
included in the amount of Taxes for such calendar year. If the Building is not
fully leased and occupied by tenants during all or any portion of a calendar
year, or if a portion of the Building becomes exempt from any Taxes, then
Landlord may make an adjustment to the amount of Taxes for such calendar year to
reflect the amount of Taxes which would have been assessed if the Building had
been fully leased and occupied by tenants during such calendar year or if such
exemption had not been applied, and the amount of any such adjustment shall be
included in the amount of Taxes for such calendar year. Notwithstanding any
provision in this Lease to the contrary, Taxes for any calendar year shall
include that amount caused by the increase in the assessed valuation of the
Building as a result of any and all improvements, additions or alteration done
or made in and about the Building in the calendar year in question or in prior
calendar years.

6.05  INSURANCE PREMIUMS. "Insurance Premiums" shall mean any premiums for
Landlord's insurance coverage described in Article 14 or other insurance
procured by Landlord relating to the Building, or the ownership, occupancy or
operations thereof.

6.06  OPERATING EXPENSES. "Operating Expenses" shall mean and include all costs
and expenses paid or incurred by or on behalf of Landlord in owning, managing,
maintaining, operating and repairing the Building, all related improvements
thereto and all machinery, equipment, landscaping, fixtures and other
facilities, including personal property used in conjunction therewith, all as
may now or hereafter exist in or on the Building. Operating Expenses shall
include, but shall not in any way be limited to except as hereafter specifically
provided, the following: (i) the cost of security and security devices and
systems; snow and ice and trash removal, cleaning and sweeping; maintenance,
repair and replacement of utility systems, elevators and escalators;
electricity, water, sewers, fuel, power, heating, lighting, air-conditioning and
ventilating, window cleaning, and janitorial or other service; (ii) the cost of
painting, uniforms, management fees, supplies or materials, sundries and sales
or use taxes on supplies, materials or services; (iii) the cost of planting and
replacing decorations, flowers and landscaping; (iv) the cost of wages and
salaries of all persons engaged in the operation, management, maintenance and
repair of the Building, and so-called fringe benefits (including, but not
limited to, social security taxes, unemployment insurance taxes, cost for
providing coverage for disability benefits, cost of any pensions,
hospitalization welfare or retirement plans, or any other similar or like
expenses incurred under the provisions of any collective bargaining agreement,
or any other cost or expense or expense reimbursement which Landlord pays or
incurs to provide benefits for employees so engaged in the operation,
management, maintenance and repair of the Building); (v) the charges of any
independent contractor who, under contract with Landlord or its representatives,
does any of the work of operating, managing, maintaining or repairing the
Building; (vi) legal and accounting expenses (except for legal fees incurred in
connection with the negotiation of leases or the collection of amounts due under
leases); (vii) all costs, expenses, charges and assessments allocable to the
Building under any reciprocal easement agreement, joint operating agreement,
declaration, covenants, or other agreement or instrument to which the Building
is subject; (viii) Insurance Premiums; and (ix) any other expense or charge,
whether or not hereinbefore mentioned, which, in accordance with generally
accepted accounting and management principles, would be considered as an expense
of owning, managing, operating, maintaining or repairing the Building, except as
specifically hereinafter provided.

                                        8
<Page>

          Operating Expenses shall not include (a) costs or other items included
within the meaning of the term "Taxes"; (b) costs of alterations of the premises
of tenants of the Building; (c) costs of capital improvements to the Building
except as noted below; (d) depreciation charges; (e) interest and principal
payments on mortgages or trust deeds on the Building; (f) real estate leasing
and brokerage commissions; and (g) any expenditure for which Landlord has been
reimbursed (other than pursuant to rent escalation or tax and operating expense
reimbursement provisions in leases), except as hereinafter provided.
Notwithstanding anything contained herein to the contrary, Operating Expenses
shall include the cost of any capital improvements to the Building or
appurtenant land which are intended to reduce Operating Expenses, or which are
required under any governmental laws, regulations or ordinances which were not
applicable to the Building or appurtenant land at the time it was constructed,
amortized over such reasonable period as Landlord shall determine, together with
interest on the unamortized cost of any such improvements (at the prevailing
construction loan rate available to Landlord on the date the cost of such
improvements was incurred).

6.07  ESTIMATES OF EXPENSES DURING VACANCY AND SERVICES TO PART OF BUILDING. If
the Building is not fully occupied by tenants during all or a portion of any
calendar year, Landlord may make appropriate adjustments for such year in the
components of Basic Costs which vary depending upon the occupancy level of the
Building, employing generally accepted accounting and management principles. Any
such adjustments shall also be deemed expenses paid or incurred by Landlord and
included in Basic Costs for such calendar year, as if the Building had been
fully occupied and Landlord had actually paid or incurred such expenses, to the
end that the actual amounts of such variable components of Basic Costs be fairly
borne by tenants occupying the Building. At any time when a service is furnished
to, or an item of Operating Expense is incurred with respect to only a portion
of the tenants of the Building, the cost of such service or the amount of such
item of Operating Expense may, if in Landlord's judgment it is appropriate to do
so, be allocated entirely to such tenants, and as appropriate Tenant's
Proportionate Share of such Operating Expenses shall be adjusted accordingly.

6.08  ESTIMATES OF ADDITIONAL RENT

      A.   Landlord may give Tenant, from time to time, written notice of its
      estimate of Additional Rent due in a calendar year. Tenant shall pay to
      Landlord, commencing on the first day of the calendar month following the
      month in which Landlord notifies Tenant of the estimated Additional Rent,
      one-twelfth (1/12) of the Additional Rent due in any said calendar year as
      estimated by Landlord. If at any time during any calendar year it appears
      to Landlord that the Additional Rent due for any calendar year will vary
      from its estimate thereof by more than ten percent (10%), Landlord may, by
      written notice to Tenant, revise its estimate for such year. Subsequent
      Additional Rent deposits by Tenant for such year shall be based on the
      revised estimate. Tenant shall make monthly payments of Additional Rent
      based on Landlord's most recent estimate thereof until Landlord notifies
      Tenant of a revision of such estimate. Tenant acknowledges that Landlord
      has not made and does not hereby make any representation or warranty
      whatsoever to Tenant as to the amount of Additional Rent or any component
      thereof which may become payable during the term of the Lease. Until
      Tenant's

                                        9
<Page>

      receipt of such estimate for any calendar year, Tenant shall pay the same
      monthly estimate as Tenant had most recently been notified of by Landlord.

      B.   Following the end of each calendar year and after Landlord shall
      deliver to Tenant a detailed statement of the actual amounts of Basic
      Costs for such calendar year. If Tenant's obligation for Additional Rent
      exceeds the deposits paid by Tenant, Landlord shall bill Tenant for the
      excess amount and Tenant shall pay to Landlord said amount within ten (10)
      days of billing. If Tenant's obligation for actual Additional Rent is less
      than the deposits paid by Tenant, Tenant shall, at Landlord's option,
      either be given a credit for the excess amount against the next Additional
      Rent payments due, or a refund of the excess so paid by Tenant, or if this
      Lease is terminated, such excess shall be credited against any amounts
      which Tenant owes Landlord pursuant to other provisions of this Lease and,
      to the extent all amounts which Tenant owes to Landlord hereunder have
      been paid, Landlord shall promptly pay such excess to Tenant. Delay in
      computing any item of Basic Costs shall neither be deemed a default by
      Landlord nor a waiver of the right to collect any item of Basic Costs.

6.09  REVIEW OF ADDITIONAL RENT. Tenant shall have the right to review all of
Landlord's bills, invoices and records concerning Additional Rent. Any such
review shall be conducted at Landlord's offices following not less than ten (10)
business days prior written notice and shall not unreasonably disrupt Landlord's
business operations. The cost of such review shall be paid by Tenant except in
the event the review reveals an error by Landlord which resulted in an
overcharge of actual (as distinguished from estimated) Additional Rent in excess
of ten percent (10%) of the total, in which event Landlord shall pay the
reasonable cost of the review (up to the amount of the overcharge). Any
undercharge or overcharge shall be paid, credited or refunded, as applicable, as
provided in Paragraph 6.08. Unless Tenant shall, by written notice to Landlord,
take exception to any item in any annual statement of Additional Rent within one
hundred eighty (180) days after the furnishing of said statement, such statement
shall be conclusively binding upon Tenant. Any amount shown by such statement to
be due to Landlord, whether or not written exception is taken to such statement,
shall be paid by Tenant as provided in Paragraph 6.08(B) above, without
prejudice to any such written exception.

6.10  SERVICE CHARGE. Tenant recognizes that late payment of Rent will result in
administrative expense to Landlord, the extent of which additional expense is
extremely difficult and economically impractical to ascertain. Tenant therefore
agrees that if Rent is not paid when due and payable pursuant to this Lease, a
late charge shall be imposed in an amount equal to three percent (3%) of the
unpaid Rent; provided however, that in the first instance within any 12-month
period during the term of the Lease no late charge shall be assessed unless
Tenant failed to make such payment within five (5) days after the date such
payment is due. The provisions of this Paragraph 6.10 in no way relieve Tenant
of the obligation to pay Rent on or before the date on which Rent is due, nor do
the terms of this Paragraph 6.10 in any way affect Landlord's remedies pursuant
to this Lease in the event Rent is unpaid after the date due.

ARTICLE 7 - UTILITY SERVICES

                                       10
<Page>

7.01  WATER SERVICE. During the term of the Lease, Landlord shall use its
commercially reasonable efforts to provide hot and cold water in common with
other tenants from the municipal mains for drinking, lavatory and toilet
purposes drawn through fixtures installed by Landlord, or by Tenant in the
Premises with Landlord's written consent. Tenant shall not waste or permit the
waste of water.

7.02  ELECTRICITY SERVICE. Adequate electrical wiring and facilities for

standard Building lighting fixtures shall be provided by Landlord and for
Tenant's incidental uses. Landlord shall permit Tenant to receive electric
service using Landlord's wire and conduits, to the extent available, suitable
and safely capable, to be used for such purposes. Electricity shall be furnished
by an approved electric utility company serving the area. Tenant shall make all
necessary arrangements directly with the utility company for separately metering
and paying for electric current furnished by it to the Premises, and Tenant
shall timely pay for all charges for electricity service billed to the Premises
during Tenant's occupancy thereof. The electricity used during the performance
of janitor service, the making of alterations or repairs in the Premises, and
the operation of any special air conditioning systems which may be required for
data processing equipment or for other special equipment or machinery installed
by Tenant, shall be paid for by Tenant. Tenant also agrees to purchase from
Landlord all lamps, bulbs, ballasts and starters, with the exception of free
standing light fixtures, used in the Premises during the term of the Lease.
Tenant shall make no alterations or additions to the electric equipment or
appliances without the prior written consent of Landlord in each instance.
Tenant covenants and agrees that at all times its use of electric current shall
never exceed the capacity of the feeders to the Building or the risers or wiring
installed thereon. Tenant will not without the written consent of Landlord use
any apparatus or device in the Premises which will in any way increase its usage
beyond the amount of electricity which Landlord determines to be reasonable for
use of the Premises as general office space. If Tenant shall require electric
current in excess of that which is reasonably obtainable from existing electric
outlets and normal for use of the Premises as general office space, then Tenant
shall first procure the consent of Landlord (which consent will not be
unreasonably withheld). Tenant shall pay all costs of installation of all
facilities necessary to furnishing such excess capacity and for such increased
electricity usage. Landlord reserves the right to require Tenant to install the
conduit, wiring and other equipment necessary to supply electricity for excess
incidental use requirements at Tenant's expense.

7.03  TELEPHONE SERVICE. Tenant shall arrange and pay for all telephone,
communications or data service installation and utilization costs in the
Premises. All wiring shall be done within the Premises only or approved Common
Areas, and Tenant's installation, repair and maintenance shall not interfere
with or disrupt the activities of any other tenant in the Building. All of
Tenant's telephone and telecommunications system requirements, and the
installation, repair, and maintenance requirements therefor, shall be submitted
in writing to Landlord and are subject to Landlord's prior approval, which shall
not be unreasonably withheld.

7.04  DISPROPORTIONATE USE. If Landlord shall from time to time reasonably
determine that the use of any utility or service in the Premises is
disproportionate to the use of other tenants, then at Landlord's request Tenant
shall install and maintain, at Tenant's expense, metering devices for checking
the use of any such utility or service in the Premises. Tenant shall pay
Landlord for the cost of such disproportionate use at rates established by
Landlord within ten (10) days after receipt of a statement therefor.

                                       11
<Page>

7.05  ADDITIONAL HVAC. Whenever, in Landlord's opinion, Tenant's use or
occupation of the Premises, including lighting, personnel, heat generating
machines or equipment, individually or cumulatively, causes the design loads for
the Building's heating and cooling equipment (the "HVAC System") to be exceeded
or to affect adversely the temperature or humidity otherwise maintained by the
HVAC System in the Premises or the Building, Landlord may, but shall not be
obligated to, temper such excess loads by installing supplementary heating or
air-conditioning units in the Premises or elsewhere where necessary. In such
event, or in the event Tenant chooses to install supplementary heating or
air-conditioning units in the Premises, the cost of such units and the expense
of installation, including, without limitation, the cost of preparing working
drawings and specifications, plus fifteen percent (15%) of such cost as an
overhead and supervision fee, shall be paid by Tenant as additional rent within
ten (10) days after Landlord's demand therefor. Alternatively, Landlord may
require Tenant to install such supplementary heating or air-conditioning units
at Tenant's sole expense. Landlord may operate and maintain any such
supplementary units, but shall have no continuing obligation to do so or
liability in connection therewith. The expense resulting from the operation and
maintenance of any such supplementary heating or air-conditioning units,
including rent for space occupied by any supplementary heating or
air-conditioning units installed outside the Premises, shall be paid by Tenant
to Landlord as additional rent at rates fixed by Landlord.

7.06  UTILITY PAYMENTS. Tenant shall pay each respective utility company
directly for any utilities serving the Premises which are metered or billed
directly to the Premises or Tenant. The cost of all utilities supplied to the
Premises which are not directly metered to the Premises shall be included in
Basic Costs.

7.07  SERVICE INTERRUPTION. Landlord does not warrant against and shall not be
liable to Tenant for any loss, injury or damage to property or otherwise caused
by or resulting from any variation, interruption, or failure of any utility
services due to any cause whatsoever, or from failure to make any repairs or
replacements or perform any maintenance. No interruption, variation, or failure
of such services incident to the making of repairs, alterations, or
improvements, or due to accident, strike, or conditions or events beyond
Landlord's control or any other reason shall be deemed an eviction or
disturbance of Tenant or relieve Tenant from paying Rent or any other of
Tenant's obligations hereunder.

7.08  DISCONTINUANCE OF SERVICES. Notwithstanding anything to the contrary
contained herein, and in addition to any of Landlord's remedies contained
herein, in the event that Tenant is in default of any of its material
obligations hereunder, Landlord shall have the right, except as restricted by
law, to discontinue providing Tenant any of the services described above without
such discontinuance being considered a constructive eviction or interference
with Tenant's use of the Premises.

ARTICLE 8 - USE, MAINTENANCE AND COMPLIANCE WITH LAWS

8.01  GENERAL USE. The Premises hereby leased shall be used by Tenant only for
the Permitted Uses and for no other purposes. Throughout the term of the Lease
Tenant shall, at Tenant's expense,

                                       12
<Page>

promptly comply with the Rules and Regulations set out in Exhibit B, and all
applicable governmental statutes, ordinances, rules, regulations, orders and
requirements in effect regulating the use of the Premises. Tenant shall not use
or permit the use of the Premises in any manner that will tend to create waste
or a nuisance, or will tend to unreasonably disturb other tenants in the
Building. Landlord may hereafter from time to time promulgate additional
reasonable rules and regulations regarding the Premises and the Building, and
Tenant shall comply with such rules and regulations, so long as such regulations
do not conflict with the Permitted Uses of the Premises by Tenant.

8.02  MAINTENANCE AND REPAIR BY TENANT. Tenant shall be responsible for all
necessary or appropriate maintenance, repair, and replacement to the Premises of
every kind or nature not hereinafter set forth specifically as the obligation of
Landlord. Tenant shall take good care of the Premises, and keep them in good

and, under the supervision or subject to the approval of Landlord and within a
reasonable period of time specified by Landlord, Tenant shall repair or replace
any damage or breakage to the Premises or the Building caused by Tenant or
Tenant's agents, employees, licensees, contractors, or invitees, or by Tenant's
equipment or installations. In the event Tenant fails to maintain, repair or

shall have the right, but not the obligation, to perform such maintenance,
repair or replacement in which event Tenant shall promptly reimburse Landlord
for its costs in providing such maintenance, repair or replacements together
with a ten percent (10%) charge for Landlord's incidental costs and expenses.
Such amounts charged to Tenant shall be deemed Rent under this Lease, payable

8.03  COMPLIANCE WITH LAWS. Tenant covenants to promptly comply throughout the
term of the Lease, at Tenant's sole cost and expense, with all laws, ordinances,
rules, regulations, and orders of any governmental bodies having jurisdiction

additions required thereby, foreseen or unforeseen, ordinary as well as
extraordinary. After the Commencement Date, Tenant will reimburse Landlord for
all expenditures made by Landlord which are required by municipal, state or
other governmental bodies due to the type or extent of Tenant's use of the
Premises. Tenant will likewise observe and comply with the requirements of all
policies of public liability, fire and other insurance at any time in force with
respect to the Building or the Premises and the personal property thereof.

permit any of its agents, contractors, employees, licensees or invitees to at
any time handle, use, manufacture, store or dispose of in or about the Premises
or the Building any (collectively "Hazardous Materials") flammables, explosives,
radioactive materials, hazardous wastes or materials, toxic wastes or materials,
or other similar substances, petroleum products or derivatives or any substance
subject to regulation by or under any federal, state and local laws and

rules and regulations issued pursuant to any of such laws or ordinances
(collectively "Environmental Laws"), nor shall

                                       13
<Page>

Tenant suffer or permit any Hazardous Materials to be used in any manner not
fully in compliance with all Environmental Laws, in the Premises or the Building
and appurtenant land or allow the environment to become contaminated with any
Hazardous Materials. Notwithstanding the foregoing, Tenant may handle, store,
use or dispose of products containing small quantities of Hazardous Materials
(such as aerosol cans containing insecticides, toner for copiers, paints, paint
remover and the like) to the extent customary and necessary for the use of the
Premises for general office purposes; provided that Tenant shall always handle,
store, use, and dispose of any such Hazardous Materials in a safe and lawful
manner and never allow such Hazardous Materials to contaminate the Premises,
Building and appurtenant land or the environment. Tenant shall protect, defend,
indemnify and hold Landlord harmless from and against any and all loss, claims,
liability or costs (including court costs and reasonable attorney's fees)
incurred by reason of any failure of Tenant to fully comply with all applicable
Environmental Laws, or the presence, handling, use or disposition in or from the
Premises of any Hazardous Materials (even though permissible under all
applicable Environmental Laws or the provisions of this Lease), or by reason of
any actual or asserted failure of Tenant to keep, observe, or perform any
provision of this Paragraph 8.05. The indemnity obligations of Tenant under this
paragraph shall survive any termination of the Lease.

ARTICLE 9 - COMMON AREAS

9.01  DEFINITION. The term "Common Areas" means all areas and facilities of the
Building not intended for lease to individual tenants, and which are instead
designed for the common use and benefit of Landlord and all or substantially all
of the tenants, their employees, agents, customers and invitees and which shall
be operated and maintained by Landlord. The Common Areas include, but not by way
of limitation, the roof, interior hallways, lobbies, elevators, common
restrooms, cafeteria or vending room facilities, if any, exterior walls, all
parking lots, loading dock and service areas, landscaped and vacant areas,
driveways, walks and curbs with facilities appurtenant to each as such areas may
exist from time to time. Landlord hereby grants to Tenant the non-exclusive use
of the Common Areas (except the roof, exterior walls, and any reserved or
designated parking) by Tenant, Tenant's employees, agents, customers, and
invitees, which use shall be subject at all times to the terms and conditions of
this Lease and the Rules and Regulations attached as Exhibit B and such
additional rules and regulations as Landlord may make pursuant to the terms
hereof.

parking spaces (numbers 65, 66, and 67) in the Building's parking lot.

ARTICLE 10 - TENANT'S FIXTURES, ALTERATIONS, AND LIENS

                                       14
<Page>

10.01 TENANT'S FIXTURES. Tenant, at Tenant's sole expense, may install in or
affix to the Premises necessary trade fixtures, personal property, equipment and
furniture, provided that such items are installed and are removable without
damage to the Building, and that such items do not exceed the weight bearing
capacity of the Premises or place any unusual demands on the utility services to
the Premises. Prior to the installation of such trade fixtures Tenant will
provide Landlord plans for their installation. Landlord may require that Tenant,
and Tenant upon demand shall, provide data regarding the weight and operating
characteristics of such trade fixtures and other property, and may deny approval
for such trade fixtures or other property if Landlord, acting reasonably,
determines that such trade fixtures will exceed Building capacities or place
unusual demands on the utility services to the Premises.

10.02 LEASEHOLD IMPROVEMENTS. Except as noted in Paragraph 10.01 Tenant shall
not make any alterations, improvements, or additions ("Leasehold Improvements")
to the Premises without the prior written consent of Landlord which consent
shall not be unreasonably withheld. Prior to Landlord's final approval of any
such Leasehold Improvements, Tenant must provide Landlord for Landlord's review
and approval: (i) acceptable construction plans and specifications, (ii) the
construction agreements between Tenant and a reputable contractor and
subcontractors (each reasonably satisfactory to Landlord), (iii) satisfactory
evidence (including, but not limited to, certificates of insurance against all
liability which may arise out of the Leasehold Improvements) that all
contractors and subcontractors will be properly insured, (iv) copies of
necessary permits and governmental authorizations, and (v) security for the
payment of all costs to be incurred in connection with the Leasehold
Improvements. Landlord may require that such insurance policies include Landlord
as an additional insured. All work shall be required to be done promptly and in
a good workmanlike manner using only good grades of materials and Tenant shall
promptly pay the cost of all such Leasehold Improvements. In addition, Tenant
shall reimburse Landlord for all sums expended for examination and approval of
the architectural and working plans and specifications for the work and for its
inspection and supervision of the work. Tenant shall also indemnify, defend and
hold Landlord harmless from any and all liabilities and costs of every kind and
description, including reasonable attorneys' fees, which may arise out of or be
connected in any way with the Leasehold Improvements or any work performed by
Tenant. Upon completing any Leasehold Improvements, Tenant shall furnish
Landlord with contractors' affidavits and full and final waivers of lien, and
all other supporting documentation as Landlord may reasonably require, all in
form satisfactory to Landlord. All Leasehold Improvements shall comply with all
insurance requirements and with all ordinances and regulations of any applicable
governmental authority. At all times, Tenant shall cause contractors and others
performing Leasehold Improvements for Tenant to work in harmony with the
contractors, agents and employees performing work in the Building for Landlord
or others, if any. All Leasehold Improvements, except movable furniture,
equipment and trade fixtures placed in the Premises at the expense of Tenant,
shall become the property of Landlord and at the election of Landlord, shall
either remain upon and be surrendered with the Premises to Landlord as a part
thereof at the termination of this Lease or shall be removed at the sole cost
and expense of Tenant.

10.03 MECHANICS' LIENS. Tenant has no authority or power to and shall not cause
or permit any mechanics' liens or other liens to be placed upon the Building or
any portion or component thereof or Landlord's interest therein whether created
by act or inaction of Tenant, operation of law, or otherwise, and in case of the
filing of any such lien or encumbrances or claim therefor, Tenant shall

                                       15
<Page>

promptly discharge same; provided, however, that Tenant shall have the right to
contest the validity or amount of any mechanics lien upon its prior posting of
security with Landlord, which security, in Landlord's sole judgment, must be
adequate to pay and discharge any such lien in full in addition to any
applicable interest, penalties and Landlord's reasonable estimate of its legal
fees. Tenant agrees to indemnify and hold Landlord harmless against any and all
liabilities, reasonable legal fees and other costs whatsoever incurred by
Landlord because of any mechanics' or other liens attributable to Tenant being
placed upon the Premises or the Building. Any mechanic's lien or claim for a
mechanic's lien which Tenant desires to contest as herein provided shall be
contested only in good faith, by appropriate proceedings diligently pursued,
and, in any event, such lien or claim for lien shall be released or removed
within six (6) months of the date such claim or lien first attached. If the lien
is not so contested and released or removed, Landlord, at its sole option and in
addition to any other available rights or remedies, may take any and all action
necessary to release and remove such lien or claim of lien (it being agreed by
Tenant that Landlord shall have no duty to investigate the validity thereof) and
Tenant shall promptly upon written notice reimburse Landlord for all sums, costs
and expenses (including but not limited to reasonable attorneys' fees) incurred
by Landlord in connection with the removal or release of any such lien or claim.

ARTICLE 11 - SERVICE AND MAINTENANCE BY LANDLORD AND RESERVATIONS

11.01 SPECIFIC RESERVATIONS. The Premises shall not include the roof, exterior
walls, foundation of the Building, or any of the Common Areas, or any other area
outside, above or below the Premises. In addition, so long as such activities do
not unreasonably interfere with Tenant's use of the Premises and reasonable
advance notice (except in emergency) is given Tenant prior to their
commencement, Landlord reserves the right to: place, install, maintain, carry
through, repair and replace such utility lines, pipes, wires, appliances,
tunneling and the like in, over, through, under and upon the Premises as may be
reasonably necessary or advisable for the servicing of the Premises or any other
portions of the Building; for such purposes, to reasonably enter upon the
Premises; and during the continuance of any of said work, to temporarily close
doors, entryways, public space and corridors to or in the Building and to
interrupt or temporarily suspend services or use of facilities, all without
affecting any of Tenant's obligations hereunder.

11.02 BUILDING ALTERATIONS BY LANDLORD. Notwithstanding any provision in this
Lease to the contrary, Landlord reserves the right at any time and from time to
time, without notice to Tenant or liability to Tenant for damage or injury to
property, person, or business and without constituting an eviction or
disturbance of Tenant's use or possession of the Premises or giving rise to any
claim for set-off or abatement of Rent: (i) to make alterations, changes and
additions to the Building (including the Common Areas), (ii) to add additional
areas to the Building and/or to exclude areas therefrom, (iii) to construct
additional buildings and other improvements on the land occupied by the
Building, (iv) to remove or relocate a part of the Building, and (v) to relocate
any other tenant in the Building, provided in each case such changes shall not
unreasonably interfere with the Permitted Uses.

11.03 SERVICES PROVIDED BY LANDLORD. Subject to such temporary interruptions
thereof as are consistent with what could normally be expected from a
well-managed building, Landlord agrees to provide the following general services
in connection with this Lease:

                                       16
<Page>

      in accordance with good standards applicable to normal occupancy of
      premises for office purposes subject to governmental regulations during
      the hours set forth in Exhibit B; provided, however, Landlord shall have
      no responsibility for failure thereof if the electrical power consumed on
      the Premises exceeds reasonable amounts as determined by Landlord, if
      Tenant installs partitions or other installations in locations which
      interfere with the proper operation of the Building systems or if the
      window covering on exterior windows is not kept fully closed;

      B.   To provide daily janitorial services to the Premises and Common Areas
      (Saturdays, Sundays and holidays excepted) in accordance with the
      standards of similar office buildings; and

      C.   To provide elevator service to each floor upon which the Premises
      are located provided such service is installed in the Building and
      provided that Landlord may prescribe the hours during which and the
      procedures under which freight elevator service shall be available and may
      limit the number of elevators providing service outside normal business
      hours.

      Landlord may (but shall not be obligated to) upon the request of Tenant
supply services to the Premises and the Building which are not provided for

prior to 1:00 p.m. of the day upon which such services are required or if such
services are required on a Saturday, Sunday or holiday, prior to 1:00 p.m. on
the business day next preceding the day for which such services are required.
The cost of any Additional Services supplied or furnished by Landlord to Tenant
shall not be included in Operating Expenses but rather shall be billed
separately to Tenant at Landlord's scheduled rate therefor from time to time, or
if there be no scheduled rate, then at the rate of one hundred fifteen percent
(115%) of Landlord's cost in providing them, such amount to be considered
additional rent hereunder. All charges for Additional Services shall be due and
payable at the same time as the installment of Base Rent with which they are
billed, or if billed separately, shall be due and payable within ten (10) days
after Tenant receives Landlord's bill therefor. Any such billings for Additional
Services shall include an itemization of the Additional Services rendered and
the charge for each such service. If Landlord shall not supply or furnish
Additional Services, only persons with prior written approval by Landlord (which
approval shall not be unreasonably withheld) shall be permitted to supply or
furnish Additional Services subject to the reasonable rules fixed by Landlord.
Tenant agrees that Landlord shall not be liable in damages (actual or
consequential), by abatement of Rent, setoff, deduction, claim, demand, or in
any other fashion, for failure to furnish or delay in furnishing any service
described in this Article 11 or for any diminution in the quality or quantity
thereof. Notwithstanding anything to the contrary contained herein, and in
addition to any of Landlord's remedies contained herein, in the event that
Tenant is in default of any of its material obligations under the Lease,
Landlord shall have the right to discontinue providing Tenant any of the
services described above without such discontinuance being considered a
constructive eviction or interference with Tenant's use of the Premises.

11.04    MAINTENANCE AND REPAIR BY LANDLORD

                                       17

           Premises) and casualty damage pursuant to Article 15.

      B.   Landlord shall not be liable for any failure to make repairs that are
      Landlord's responsibility herein until and unless Landlord is actually
      aware of the problem requiring repair and Landlord shall have had a
      reasonable time thereafter to make such repairs. Landlord reserves the
      right to the exclusive use of the roof and exterior walls of the Building.
      If any portion of the Premises which Landlord is obligated to maintain or
      repair is damaged by the negligence or willful actions or omissions of
      Tenant, its agents, employees, contractors, or invitees, then repairs or

      exercising any or all of the foregoing rights hereby reserved without

      such entry except that required in an emergency or for the provision of
      normal Landlord services, Landlord shall provide Tenant reasonable notice
      thereof; and

      M.   To enforce the Rules and Regulations attached as Exhibit B.

ARTICLE 13 - LANDLORD'S INABILITY TO PERFORM

13.01 LANDLORD'S INABILITY TO PERFORM. If by reason of inability to obtain

or intended as personal covenants, undertakings, or agreements by Landlord or
its partners, members, officers, directors, trustees, agents, employees, legal
representatives, successors or assigns. Any liability for damage or breach or
non-performance by Landlord shall be collectible only from Landlord's interest
in the Building and no personal liability is assumed by, nor at any time may be
asserted against, Landlord, its partners, members, officers, directors,
trustees, agents, employees, legal representatives, successors or assigns.

ARTICLE 14 - INSURANCE / INDEMNIFICATION

14.01 TENANT'S INSURANCE

      A.   Tenant covenants and agrees to maintain at all times during the term
      of the Lease, or any renewal thereof, a policy or policies of commercial
      general liability insurance against claims for personal injury, death or
      property damage (on an occurrence basis) with respect to the business
      carried on by Tenant in or from the Premises and Tenant's use and
      occupancy of the Premises and any other part of the Building, with
      coverage of not less than $1,000,000.00 combined single limit in respect
      to personal injury and/or death and/or property damage, or any other
      amount which Landlord may reasonably require, and comprehensive
      automobile liability insurance covering all owned, leased and hired
      automobiles of Tenant in the same amount. Such insurance shall include
      Landlord (and any other party requested by Landlord)

                                       20
<Page>

      as an additional insured and shall protect Landlord with respect to any
      claims as if Landlord were separately insured.

      B.   Tenant covenants and agrees to maintain at all times during the term
      of the Lease, or any renewal or extension thereof, insurance protection
      against "all risk of direct physical loss", as defined by Causes of Loss
      Special Form (CP 1030 or its equivalent), for the full replacement cost
      of all Leasehold Improvements and of all office furniture, trade
      fixtures, office equipment, merchandise and all other items of Tenant's
      property on the Premises, including business interests of Tenant and
      property under the care, custody or control of Tenant, which insurance

      days prior written notice, such requirement to be made on the basis that
      the required insurance is customary at the time for prudent tenants of
      properties similar to the Building.

14.02 LANDLORD'S APPROVAL. All insurance required to be maintained by Tenant
shall be on terms, with deductibles and with insurers satisfactory to Landlord,
which approval shall not be unreasonably withheld. Each policy shall contain an
undertaking by the insurer so that no material change adverse to Landlord will

than thirty (30) days' prior written notice to Landlord of the intended change,
lapse or cancellation. Whenever Landlord requests, Tenant shall furnish
Landlord, certificates or other evidences acceptable to Landlord regarding the
insurance required to be effected by Tenant hereunder. If Tenant shall fail to
take out, renew or keep in force such insurance, or if the evidences submitted
to Landlord are unacceptable to Landlord (or no such evidences are submitted
within a reasonable period after request therefor by Landlord), then Landlord
may give to Tenant written notice requiring compliance with this paragraph and
specifying the respects in which Tenant is not then in compliance. If Tenant
does not within forty-eight (48) hours provide appropriate evidence of
compliance with this paragraph, Landlord may (but shall not be obligated to)

under this Lease or otherwise, and Tenant shall pay all premiums and other
reasonable expenses incurred by Landlord to Landlord as additional rent on
demand.

shall determine. Landlord shall not in any way or manner insure any property of
Tenant or any property that may be in the Premises but not owned by Landlord.
Landlord shall keep the Building insured for the benefit of Landlord against
loss or damage by fire and such other risk or risks of a similar or dissimilar
nature as are now, or may in the future be, customarily covered with respect to
buildings and improvements similar in construction, general location, use,
occupancy and design to

                                       21
<Page>

the Building, including, but without limiting the generality of the foregoing,
windstorms, hail, explosion, vandalism, malicious mischief, and civil commotion,
provided coverage is obtainable. Landlord shall also maintain, for its benefit
and the benefit of its managing agent, general liability insurance against
claims for personal injury, death or property damage occurring upon, in or about
the Building, and any other insurance that Landlord deems appropriate and is
customarily carried with respect to buildings and improvements similar in
construction, general location, use, occupancy and design to the Building,
including loss of rents coverage.

14.04 LANDLORD'S LIABILITY/PROPERTY DAMAGE OR LOSS. Tenant agrees, to the extent
not expressly prohibited by law, that Landlord, its officers, directors,
employees, legal representatives, agents and servants shall not be liable for,
and Tenant hereby waives all claims for, damage or loss to property and business
sustained during the term of the Lease by Tenant occurring in or about the
Building or the Premises, resulting directly or indirectly from any existing or
future condition, defect, matter or thing in, or on, or about the Building or
the Premises, or from equipment or appurtenances becoming out of repair or from
accident, or from any occurrence or act or omission of Landlord, its agents,
employees or servants, or another tenant or occupant of the Building or any
other person. This paragraph shall apply especially, but not exclusively, to
damage caused as aforesaid or by flooding, sprinkler leakage, snow, frost,
steam, excessive heat or cold, falling plaster, broken glass, sewage, gas, odors
or noise, or the bursting or leaking of pipes or plumbing fixtures, and shall
apply equally, whether any such damage or loss results from the act or omission
of other tenants or occupants in the Building or any other persons. Tenant
agrees to look exclusively to Tenant's insurance coverage in the event of such
loss.

14.05 INDEMNIFICATION OF LANDLORD/THIRD PARTY CLAIMS

      A.   Subject to Paragraph 14.06 below, to the extent not expressly
      prohibited by law, and except for damage to the Building covered by the
      insurance noted in Paragraph 14.03, Tenant shall indemnify and defend
      Landlord, its subsidiaries, directors, officers, employees, legal
      representatives, servants and agents and save them harmless from and
      against any and all loss (including loss of rents payable by Tenant or
      other tenants) and against all claims, actions, damages, liability and
      expense brought by any person(s), firm(s), or corporation(s) in connection
      with loss of life, bodily and personal injury or property damage arising
      from (i) any occurrence in, upon or at the Premises, (ii) any occurrence
      in, upon or at the Building occasioned wholly or in part by any act or
      omission of Tenant, its agents, contractors, employees, servants,
      licensees, concessionaires or invitees or by anyone permitted to be on the
      Premises by Tenant, or (iii) Tenant's negligent performance of or failure
      to perform any of its obligations under this Lease.

      B.   Anything herein to the contrary notwithstanding, in the event any
      damage to the Building arising wholly or in part out of any act or
      omission of Tenant, its agent, employees, contractors, or invitees, and
      all or any portion of Landlord's loss is "deductible" under Landlord's
      insurance policies, Tenant shall pay to Landlord on demand the amount of
      such deductible loss as additional rent.

                                       22

14.06 WAIVER OF SUBROGATION. Notwithstanding anything to the contrary contained
in this Lease, Tenant and Landlord release each other and waive any right of
recovery, whether direct or by way of subrogation, against each other, their
agents, officers and employees, for any loss of or damage to their respective
property, which occurs in or about the Building or Premises (regardless of the
cause or origin, including negligence of either party, or their agents, officers
or employees) to the extent that such loss or damage is covered under the
insurance required hereunder. The parties agree to immediately give each
insurance company providing insurance relating to this Lease, notice of the
terms of these mutual waivers, and, if necessary, to have the insurance policies
properly endorsed, so as to prevent the invalidation of the insurance coverages
by reason of the mutual waivers contained in this paragraph.

ARTICLE 15 - DAMAGE OR DESTRUCTION

15.01 RECONSTRUCTION FOLLOWING DAMAGE. Except as noted below, if the Premises or
Building are damaged or destroyed during the term of the Lease, Landlord shall
diligently repair or rebuild the Premises, in compliance with all applicable
laws, ordinances and regulations, to substantially the same condition in which
it existed as of the Commencement Date. Landlord shall be under no obligation to
restore any Leasehold Improvements made by Tenant after the Commencement Date.
Tenant acknowledges that Landlord shall be entitled to the full proceeds of any
insurance coverage, whether carried by Landlord or Tenant, for damage to those
items provided by Landlord either directly or through an allowance to Tenant,
which Landlord is obligated to or elects to restore as herein provided. Landlord
shall not be obligated to expend in restoration an amount in excess of the
proceeds of insurance recovered by Landlord with respect to such damage and
which are usable by Landlord for such restoration as permitted by any mortgagee.
If Landlord fails within one hundred eighty (180) days after such damage occurs
to substantially restore the Premises or eliminate any substantial interference
with Tenant's use of the Premises, Tenant may, by providing written notice to
Landlord no later than five (5) days after expiration of said one hundred eighty
(180) day period, terminate this Lease as of the end of the thirtieth (30th) day
after Landlord's receipt of such written notice, unless Landlord has
substantially restored the Premises or eliminated any substantial interference
with Tenant's use of the Premises within such 30-day period, in which case the
Lease shall remain in full force and effect. Such one hundred eighty (180) day
period shall be extended for reasonable delay caused by adjustment of insurance
loss or Force Majeure.

15.02 EXCESSIVE DAMAGE. If the Building or Premises is damaged or destroyed to
the extent that the Premises or Building cannot, in Landlord's sole judgment, be
fully repaired or restored by Landlord within one hundred eighty (180) days
after the date of the damage or destruction, Landlord may terminate this Lease
by providing Tenant written notice of Landlord's election within sixty (60) days
after the damage or destruction.

15.03 DAMAGE OR DESTRUCTION AT END OF TERM. If the Building or the Premises is
damaged or destroyed during the last twelve (12) months of the term of the
Lease, and the Premises or the Building cannot, in Landlord's sole judgment, be
fully repaired or restored by Landlord within sixty (60) days after the damage
or destruction, either Landlord or Tenant may terminate this Lease upon written
notice to the other.

                                       23
<Page>

15.04 RENT ABATEMENT. If the Premises are rendered untenantable but this Lease
is not terminated, all Rent shall abate (except as noted otherwise herein) from
the date of the damage or destruction until the restoration of the Premises is
substantially completed. If only a portion of the Premises is untenantable, Rent
shall be prorated on a per diem basis and apportioned in accordance with the
portion of the Premises which is usable by Tenant until the restoration of the
Premises is substantially completed.

ARTICLE 16 - ASSIGNMENT AND SUBLETTING

16.01 ASSIGNMENT AND SUBLETTING GENERALLY

      A.   Except as noted hereafter, Tenant shall not permit or suffer to exist
      any assignment, transfer, mortgage, encumbrance, conveyance, lien or
      hypothecation of this Lease, voluntarily or by operation of law, nor
      sublet or otherwise transfer its interest in all or any part of the
      Premises or permit the use of the Premises by any parties other than
      Tenant or its employees without the prior written consent of Landlord. Any
      action by Tenant in violation of this Paragraph 16.01 shall be void and of
      no effect.

      B.   If Tenant wishes to assign this Lease or sublet all or any part of
      the Premises it shall first give notice in writing in the manner required
      under this Lease of such intention to Landlord, furnishing Landlord with a
      copy of the proposed assignment or sublease document and full information
      as to the identity and financial status of the proposed assignee or
      subtenant. Thereupon, Landlord shall have, within fifteen (15) days of
      receipt of such notice and documents and information, the right to
      (i) terminate this Lease, or so much thereof as Tenant proposes to
      sublease, or (ii) approve or reject such assignment or subletting by
      written notice to Tenant. If no such response is given, Landlord shall be
      deemed to have elected to approve the assignment or subletting.
      Notwithstanding any assignment or sublease, Tenant shall remain liable
      hereunder and shall not be released without the express written agreement
      of Landlord to such release. The consent by Landlord to any assignment or
      subletting shall not constitute a waiver of the necessity for such consent
      to any subsequent assignment or subletting.

      C.   If Tenant's notice covers all of the Premises and if Landlord
      exercises its right to terminate this Lease as to such space, then the
      term of the Lease shall expire and end on the date stated in Tenant's
      notice for the commencement of the proposed assignment or sublease as
      fully and completely as if that date had been the expiration date. If,
      however, Tenant's notice covers less than all of the Premises, and if
      Landlord exercises its right to terminate this Lease with respect to such
      space described in Tenant's notice, then as of the date stated in Tenant's
      notice for the commencement of the proposed sublease, (i) the Base Rent
      and Tenant's Proportionate Share shall be adjusted on the basis of the
      number of rentable square feet retained by Tenant, (ii) Tenant shall on
      demand by Landlord pay to Landlord as additional rent the reasonable cost
      to physically divide and separate the parts of the Premises, (iii) Tenant
      shall upon demand pay to Landlord as additional rent fifteen percent (15%)
      of the

                                       24
<Page>

      amount payable under clause (ii) above to reimburse Landlord for all
      overhead, general conditions, fees and other costs and expenses arising
      from Landlord's involvement in such work, and (iv) Tenant shall execute
      and deliver to Landlord such amendments to this Lease as Landlord may
      reasonably require to evidence the partial termination of this Lease and
      this Lease as so amended shall continue thereafter in full force and
      effect.

      D.    Landlord shall not be deemed to have unreasonably withheld its
      consent to any assignment or sublease if its consent is withheld because
      (a) Tenant is then in default under this Lease or a notice of termination
      of this Lease or Tenant's right to possession hereunder shall have been
      given; (b) in the case of a sublease, the division of the Premises would
      result in a violation of any applicable law, ordinance, code or
      governmental rule or regulation; (c) in the reasonable judgment of
      Landlord, the proposed subtenant or assignee is of a character or is
      engaged in a business which would be deleterious to the reputation of
      Landlord or of the Building; (d) the proposed assignee or subtenant is not
      sufficiently responsible to perform its obligations under this Lease or
      the proposed sublease, as the case may be; or (e) the proposed assignee or
      subtenant is a tenant or occupant of the Building or is actively
      negotiating with Landlord or an agent of Landlord for space in the
      Building; provided, however, that the foregoing are merely examples of
      reasons for which Landlord may reasonably withhold its consent and shall
      not be deemed exclusive of any permitted reasons for reasonably
      withholding consent, whether similar or dissimilar to the foregoing
      examples.

      E.   If a subletting or assignment is so approved and the rents under such
      a sublease or assignment are greater than the Rents provided for herein,
      then Tenant shall pay to Landlord as additional rent 50% of the excess
      rents as and when received. Tenant shall furnish Landlord with a sworn
      statement, certified by an officer of Tenant or an independent certified
      public accountant, setting forth in detail the computation of excess
      rents, and Landlord, or its representatives, shall have access to the
      books, records and papers of Tenant in relation thereto, and the right to
      make copies thereof. If a part of the consideration for such sublease or
      assignment shall be payable other than in cash, the payment to Landlord
      shall be payable in such form as is reasonably satisfactory to Landlord.
      For purposes of this Paragraph 16.01(E), the term "excess rents" shall
      mean the excess, if any, of (i) all amounts received or to be received in
      the form of cash, cash equivalents, and non-cash consideration by Tenant
      from any assignee or sublessee over (ii) the sum of the Rent payable to
      Landlord hereunder (or, in the case of a sublease of a portion of the
      Premises, the portion of the Rent which is allocable on a per square foot
      basis to the space sublet), plus the amount of any reasonable advertising
      expenses, brokers' commissions, reasonable attorneys' fees, costs of
      tenant improvements and other actual, out-of-pocket expenses incurred by
      Tenant in connection with such assignment or sublease, all of which shall
      be, in the case of a sublease, amortized over the term of the sublease for
      the purpose of calculating the amounts of the periodic payments due to
      Landlord hereunder.

      F.   In no event shall Tenant assign this Lease or enter into any
      sublease, license, concession or other agreement for use, occupancy or
      utilization of any part of the Premises which provides for a rental or
      other payment for such use, occupancy or utilization based in whole or in
      part on the income or profits derived by any person from the Premises
      leased,

                                       25
<Page>

      used, occupied or utilized, and Tenant agrees that all assignments,
      subleases, licenses, concessions or other agreements for use, occupancy or
      utilization of any part of the Premises shall provide that the person
      having an interest in the possession, use, occupancy or utilization of the
      Premises shall not enter into any lease, sublease, license, concession or
      other agreement for use, occupancy or utilization of space in the Premises
      which provides for a rental or other payment for such use, occupancy or
      utilization based in whole or in part on the income or profits derived by
      any person from the Premises leased, used, occupied or utilized and any
      such purported assignment, sublease, license, concession or other
      agreement shall be absolutely void and ineffective as a conveyance of any
      right or interest in the possession, use, occupancy or utilization of any
      part of the Premises. In addition, in no event shall Tenant assign this
      Lease or enter into any sublease, license, concession or other agreement
      for use, occupancy or utilization of any part of the Premises which
      provides to a tenant of the Premises services other than those usually or
      customarily rendered in connection with the rental of space for occupancy
      only.

      G.   Tenant shall pay to Landlord upon demand by Landlord, notwithstanding
      that Landlord may have withheld its consent to any transfer contemplated
      by this Article 16, an amount sufficient to reimburse Landlord for all
      reasonable costs and expenses incurred by it, including but not limited to
      reasonable attorney's fees, in determining whether to grant or withhold
      any consent contemplated by this Article or otherwise in connection with
      any assignment, subletting or other transfer of Tenant's interest in this
      Lease, or any attempt to do any of the foregoing.

      H.   Any assignment or subletting by Tenant of all or any portion of the
      Premises shall automatically operate to terminate each and every special
      right, option, or election, if any exist, belonging to Tenant, including
      by way of illustration, but not limitation, any option to expand its
      Premises, to extend or renew the term of the Lease for all or any portion
      of the Premises, or to terminate as to all or any portion of the Premises
      - i.e. such rights and options shall cease as to both space sublet or
      assigned and as to any portion of the original Premises retained by
      Tenant.

16.02 SALE OF INTEREST IN TENANT. The transfer of a majority of the issued and
outstanding capital stock or membership interests, or sale or transfer of
substantially all of the assets of any corporate or limited liability company
tenant or subtenant of this Lease (including without limitation by way of any
merger, consolidation or other reorganization of Tenant, or any issuance, sale,
gift, transfer or redemption of any capital stock or membership interest,
whether voluntary, involuntary, or by operation of law, or any combination of
any of the foregoing transactions) or a majority of the total interest in the
profits, losses, and capital of any partnership tenant or subtenant (including
without limitation by way of any withdrawal or admittance of a partner or any
change in any partners interest in Tenant, whether voluntary, involuntary or by
operation of law, or any combination of any of the foregoing transactions),
however accomplished, and whether in a single transaction or a series of related
or unrelated transactions, shall be deemed an assignment of this Lease or of
such sublease.

16.03 MERGERS AND CONSOLIDATIONS. The foregoing notwithstanding, Tenant may,
without Landlord's consent (but only after notice to Landlord), and without
triggering Landlord's right of

                                       26
<Page>

recapture provided in this Article 16, assign this Lease or sublet the Premises
to (a) any entity that is the parent corporation or wholly-owned subsidiary of
Tenant, or (b) any owner of 10% or more of the outstanding interest in Tenant,
or (c) any entity resulting from a sale, merger, or consolidation of Tenant upon
the following conditions: (i) that the total assets and net worth of such
assignee shall be equal to or more than that of Tenant immediately prior to such
sale, consolidation, or merger; (ii) that Tenant is not at such time in default
hereunder; and (iii) that such successor shall execute an instrument in writing
in form and substance acceptable to Landlord fully assuming all of the
obligations and liabilities imposed upon Tenant hereunder and shall deliver the
same to Landlord. Tenant shall not be relieved of its obligations in the event
of such assignment.

ARTICLE 17 - ASSIGNMENT BY LANDLORD

17.01 ASSIGNMENT BY LANDLORD. The term "Landlord" as used in this Lease, so far
as covenants or obligations on part of Landlord are concerned, shall be limited
to mean and include only the owner or owners at the time in question of the fee
of the Premises, and in the event of any transfer or transfers of the title to
such fee, Landlord herein named (and in case of any subsequent transfers or
conveyances, the then grantor) shall be automatically freed and relieved, from
and after the date of such transfer or conveyance, of all liability as respects
the performance of any covenants or obligations on the part of Landlord
contained in this Lease thereafter to be performed; provided that any funds in
the hands of such Landlord or the then grantor at the time of such transfer, in
which Tenant has an interest, shall be turned over or credited to the grantee,
and any obligation then due and payable to Tenant by Landlord or the then
grantor under any provisions of this Lease, shall be paid to Tenant or assumed
by the grantee.

ARTICLE 18 - MORTGAGE AND TRANSFER

18.01 RIGHT TO TRANSFER

      A.   Landlord shall have the right to transfer, mortgage, pledge or
      otherwise encumber, assign, sell, sell and leaseback, lease (such lease
      being hereinafter referred to as a "Ground Lease" and the lessor
      thereunder as a "Ground Lessor") and convey, in whole or in part, the
      Premises, the Building, this Lease, and all or any part of the rights now
      or thereafter existing and all rents and amounts payable to Landlord under
      the provisions hereof. Nothing herein contained shall limit or restrict
      any such rights, and the rights of Tenant under this Lease shall be
      subject and subordinate to all instruments executed and to be executed in
      connection with the exercise of any such rights, including, but not
      limited to, the lien of any mortgage, deed of trust, or security agreement
      now or hereafter placed upon Landlord's interest in the Premises (such
      mortgage, deed of trust or security interest being hereinafter referred to
      as a "Mortgage" and the obligee thereunder as a "Mortgagee"). This
      paragraph shall be self-operative. However, Tenant covenants and agrees to
      execute and deliver upon demand such further instruments subordinating
      this Lease to the lien of any such Mortgage as shall be requested by
      Landlord and/or proposed Mortgagee, provided such Mortgagee shall agree
      not to interfere with Tenant's use and possession of the Premises pursuant
      to the terms hereof so

                                       27
<Page>

      long as Tenant is not in default hereunder. If any Mortgage is foreclosed
      or Landlord's interest under this Lease is conveyed or transferred in lieu
      of foreclosure, or if any Ground Lease is terminated:

           (i)   No person or entity which, as the result of any of the
           foregoing has succeeded to the interest of Landlord in this Lease
           (any such person or entity being hereafter called a "Successor")
           shall be liable for any default by Landlord or any other matter which
           occurred prior to the date such Successor succeeded to Landlord's
           interest in this Lease nor shall such Successor be bound by or
           subject to any offsets or defenses which Tenant may have against
           Landlord or any other predecessor in interest to such Successor;

           (ii)  Upon request of any Successor, Tenant will attorn, as Tenant
           under this Lease, subject to the provisions of this Paragraph 18.01
           to each Successor and will execute and deliver such instruments as
           may be necessary or appropriate to evidence such attornment within
           ten (10) days after receipt of a written request to do so; and

           (iii) No Successor shall be bound to recognize any prepayment of Rent
           by more than thirty (30) days.

      B.   Notwithstanding anything to the contrary contained herein, any
      Mortgagee or Ground Lessor may subordinate, in whole or in part, its
      Mortgage or Ground Lease (as the case may be) to this Lease by sending
      Tenant notice in writing subordinating such Mortgage or Ground Lease to
      this Lease, and Tenant agrees to execute and deliver to such Mortgagee or
      Ground Lessor such further instruments consenting to or confirming the
      subordination of such Mortgage or Ground Lease to this Lease and
      containing such other provisions which may be requested in writing by such
      Mortgagee or Ground Lessor within ten (10) days after notice to Tenant of
      such request.

      C.   Whether or not any Mortgage is foreclosed or any Ground Lease is
      terminated or any Successor succeeds to any interest of Landlord under
      this Lease, no Mortgagee, Ground Lessor, Successor or other successor of
      Landlord's interest in this Lease shall have any liability to Tenant for
      any security deposit paid to Landlord by Tenant hereunder, unless such
      security deposit has actually been received by such person.

      D.   Should any prospective Mortgagee or Ground Lessor require a
      modification or modifications of this Lease, which modification or
      modifications will not cause an increased cost or expense to Tenant or in
      any other way materially or adversely change the rights and obligations of
      Tenant hereunder, or diminish the duties or liabilities of Landlord, then
      and in such event, Tenant agrees that this Lease may be so modified and
      agrees to execute whatever documents are required therefor and deliver the
      same to Landlord within ten (10) days following the request therefor.
      Should any prospective Mortgagee or Ground Lessor require execution of a
      short form of Lease for recording (containing, among other customary
      provisions, the names of the parties, a description of the Premises and
      the term of the Lease),

                                       28
<Page>

      Tenant agrees to execute such short form of Lease and deliver the same to
      Landlord within ten (10) days following the request therefor.

      E.   Tenant agrees that the provisions of this paragraph shall remain in
      full force and effect, notwithstanding that any Mortgagee or Ground Lessor
      may directly or indirectly own or have an interest in Landlord, or in the
      Building in addition to its interest as Mortgagee or Ground Lessor.

18.02 ESTOPPEL LETTER. Tenant covenants and agrees to execute and deliver to
Landlord within ten (10) days of written request from Landlord, estoppel letters
setting forth: (i) the date of this Lease and any amendments thereto, the
Commencement Date, and any rights or options to extend or renew this Lease or
the term of the Lease or to purchase or of first refusal or offer with respect
to the Premises or the Building, (ii) the date through which Rents have been
paid hereunder, (iii) the amount of any security deposit held by Landlord,
(iv) whether Tenant is in occupancy of the Premises and the improvements and
space required to be furnished by Landlord with the Premises and the Building
have been completed and paid for in all respects as required by this Lease,
(v) whether the Lease is in full force and effect, (vi) whether Landlord or
Tenant is in default under the Lease and whether there are defenses or offsets
against the enforcement thereof, and setting forth such defaults, defenses or
offsets claimed by Tenant, (vii) whether Tenant is subject to any bankruptcy,
insolvency or similar proceedings in any federal, state or other court or
jurisdiction, and (viii) any other information which Landlord or its mortgagee
or prospective mortgagee or purchaser may reasonably require relating to the
Lease, which may include Tenant financial statements.

18.03 DELIVERY OF TRANSFER DOCUMENTS. If Tenant shall fail to deliver any
subordination document, attornment document, or estoppel letter that may be
submitted to Tenant under this Article 18 within ten (10) days after the request
by Landlord or any other permitted party, as the case may be, (i) Tenant hereby
makes, constitutes and irrevocably appoints Landlord as Tenant's
attorney-in-fact (such power of attorney being coupled with an interest) to
execute and deliver any such instruments for and in the name of Tenant, and
(ii) Tenant shall pay Landlord, as additional rent, a $100 per day penalty from
the end of the initial ten (10) day period until the date such documents are
signed and received by Landlord.

ARTICLE 19 - EMINENT DOMAIN

19.01 EMINENT DOMAIN. If the Premises, the Building, or such a substantial part
thereof, which in Landlord's reasonable judgment renders the remainder unfit for
the intended uses, shall be taken by any competent authority under the power of
the eminent domain or be acquired for any public or quasi-public uses or
purpose, the term of the Lease shall cease and terminate upon the effective date
of the taking and Tenant shall have no claim against Landlord for the value of
any unexpired term of the Lease. If any part of the Building is taken by any
competent authority under the power of eminent domain or is acquired for any
public or quasi-public uses or purpose, or if the configuration or grade of any
street or alley or other improvement or structure adjacent to the Building is
changed and such taking, or acquisition, or change of grade or configuration
makes it necessary or desirable in Landlord's judgment to remodel the Building
to conform to the taking, acquisition, or changed grade

                                       29
<Page>

or configuration, Landlord shall have the right to terminate this Lease after
having given written notice of termination to Tenant not less than ninety (90)
days prior to the date of termination designated in the notice. In either of
said events, Rent at the then current rate shall be apportioned as of the date
of the termination. If any portion of the Premises is so taken and the Lease is
not terminated, then Base Rent and Tenant's Proportionate Share shall be
equitably reduced to reflect the new rentable square footage of the Premises. No
money or other consideration shall be payable by Landlord to Tenant for the
right of termination and Tenant shall have no right to share in the condemnation
award or in any judgment for damages caused by the taking or the change of
grade. However, nothing in this paragraph shall preclude Tenant from
independently seeking an award from the authority for any damages or relocation
benefits which Tenant is entitled to under governing law, provided that such
separate award shall not reduce the award or judgment recoverable by Landlord.

ARTICLE 20 - DEFAULT AND REMEDIES

20.01 DEFAULT GENERALLY. Tenant shall be deemed in default under the terms of
this Lease if any of the following events occur:

      A.   Tenant shall have failed to pay an installment of Base Rent,
      Additional Rent or any other amount payable hereunder, and such failure
      shall be continuing for a period of more than five (5) days after written
      notice to Tenant that such amount was due;

      B.   There shall be a default under any term, condition, covenant, or
      other obligation on the part of Tenant to be kept, observed or performed
      hereunder (other than a condition, covenant, agreement or other obligation
      to pay Base Rent, Additional Rent or any other amount of money) and such
      default shall be continuing for a period of more than fifteen (15) days
      after written notice to Tenant; provided, however, if such default may not
      be practicably cured by Tenant within such fifteen (15) day period, and
      provided further Tenant shall commence to cure the default within the
      fifteen (15) day period, the fact that the default is not cured within the
      fifteen (15) day period shall not constitute a breach of the Lease so long
      as Tenant diligently proceeds to cure the default and such default is
      cured within a reasonable period thereafter. Notwithstanding the fifteen
      (15) day period for cure noted above, if the default creates a hazardous
      situation or involves disturbance of the quiet enjoyment of other Building
      tenants, Tenant must cure the default immediately upon notice;

      C.   If any policy of insurance upon the Building or any part thereof
      shall be canceled or threatened with cancellation by the insurer by reason
      of the use or occupation of the Premises by Tenant, or any assignee,
      sub-tenant or licensee of Tenant, or anyone permitted by Tenant to be upon
      the Premises, and Tenant after receipt of written notice from Landlord
      shall have failed to take such immediate steps with respect to such use or
      occupation as shall enable Landlord to reinstate or avoid cancellation (as
      the case may be) of such policy of insurance;

      D.   The Premises shall be vacated or abandoned, or remain unoccupied for
      fifteen (15) consecutive days or more while capable of being occupied,
      unless Tenant has provided Landlord prior written notice of its intent to
      vacate or abandon the Premises;

                                       30
<Page>

      E.   The balance of the term of the Lease or any other interest of Tenant
      in this Lease or any of the goods and chattels of Tenant shall at any time
      be seized or levied in execution, attachment or other legal process; or

      F.   Any of the following shall be done or suffered to be done: (i) Tenant
      shall make any assignment for the benefit of creditors; (ii) Tenant shall
      become the subject of commencement of an involuntary case under the
      federal bankruptcy law as now or hereafter constituted, or of a petition
      against Tenant seeking reorganization, arrangement, adjustment or
      composition of or in respect of Tenant under the federal bankruptcy law as
      now or hereafter constituted, or under any other applicable federal or
      state bankruptcy, insolvency, reorganization or other similar law, or
      seeking the appointment of a receiver, liquidator, or assignee, custodian,
      trustee, sequestrator (or similar official) of Tenant or any substantial
      part of its property, or seeking the winding-up or liquidation of its
      affairs and such involuntary case or petition is not dismissed within
      sixty (60) days after the filing thereof; (iii) Tenant shall commence a
      voluntary case or institutes proceedings to be adjudicated a bankrupt or
      insolvent, or consents to the institution of bankruptcy or insolvency
      proceedings against it, under the federal bankruptcy laws as now or
      hereafter constituted or any other applicable federal or state bankruptcy
      or insolvency or other similar law, or Tenant rejects this Lease pursuant
      to a bankruptcy filing, or consents to the appointment of or taking
      possession by a receiver or liquidator or assignee, trustee, custodian,
      sequestrator (or other similar official) of Tenant or of any substantial
      part of its property, or admits in writing its inability to pay its debts
      generally as they become due; (iv) Tenant, its stockholders or its
      governing Board of Directors, Managers, or Partners, or any committee
      thereof takes any action contemplating, in preparation for or in
      furtherance of any of the occurrences, steps or proceedings in items
      (ii) or (iii) above; (v) Tenant, if a corporation, shall take any steps or
      suffer any order to be made for its winding-up or termination of its
      corporate existence, not approved by Landlord.

20.02 LANDLORD'S REMEDIES. Landlord shall have the following rights and
remedies, all of which are cumulative and not alternative and not to the
exclusion of any other or additional rights and remedies in law or equity
available to Landlord by statute or otherwise:

      A.   to remedy or attempt to remedy any default of Tenant, and in doing so
      to make any payments due or alleged to be due by Tenant to third parties
      and to enter upon Premises to do any work or other things therein (without
      such entry being in any way deemed a repossession of the Premises or a
      termination of this Lease), and in such event all reasonable expenses of
      Landlord in remedying or attempting to remedy such default shall be
      payable by Tenant to Landlord on demand;

      B.   to terminate this Lease forthwith by leaving upon the Premises or by
      affixing to an entrance door to the Premises or otherwise delivering to
      Tenant a notice terminating the Lease, in which event the term of the
      Lease and all right, title and interest of Tenant hereunder shall end on
      the date stated in the notice;

                                       31
<Page>

      C.   to terminate the right of Tenant to possession of the Premises
      without terminating this Lease, whereupon the right of Tenant to
      possession of the Premises or any part thereof shall cease on the date
      stated in such notice;

      D.   to enforce the provisions of this Lease and to enforce and protect
      the rights of Landlord hereunder by a suit or suits in equity and/or at
      law for the specific performance of any covenant or agreement contained
      herein, and for the enforcement of any other appropriate legal or
      equitable remedy, including without limitation (i) injunctive relief,
      (ii) recovery of all monies due or to become due from Tenant under any of
      the provisions of the Lease, and (iii) any other damages incurred by
      Landlord by reason of Tenant's default under this Lease.

20.03 DAMAGES

      A.   If Landlord exercises any of the remedies provided for in
      subparagraph 20.02(B) or (C) above, Tenant shall surrender possession of
      and vacate the Premises and immediately deliver possession thereof to
      Landlord, and Landlord may re-enter and take complete and peaceful
      possession of the Premises.

      B.   If Landlord terminates the right of Tenant to possession of the
      Premises without terminating this Lease, such termination of possession
      shall not release Tenant, in whole or in part, from Tenant's obligation to
      pay Rent hereunder for the full term of the Lease. Furthermore the present
      value (such present value to be computed on the basis of a per annum
      discount rate equal to seven percent (7%)) of the aggregate amount of Rent
      for the period from the date stated in the notice terminating possession
      to the date of the expiration of the term of the Lease absent such
      termination shall, at the option of Landlord, be immediately due and
      payable by Tenant to Landlord, together with any other monies due
      hereunder, and Landlord shall have the right to immediate recovery of all
      such amounts. In the alternative, Landlord shall have the right from time
      to time to recover from Tenant (without the need to commence new process),
      and Tenant shall remain liable for, all Rent not theretofore accelerated
      and paid pursuant to the foregoing sentence, as well as for any other sums
      thereafter accruing as they become due under this Lease during the period
      from the date of such notice of termination of possession to the date the
      term of the Lease would expire if not terminated early. In any such case,
      Landlord may, but shall be under no obligation to (except to the extent
      required by law), relet the Premises or any part thereof for the account
      of Tenant for such rent, for such time (which may be for a term extending
      beyond the term of the Lease) and upon such terms as Landlord in
      Landlord's sole discretion shall determine, and Landlord shall not be
      required to accept any tenant offered by Tenant or to observe any
      instructions given by Tenant relative to such reletting; provided,
      however, that any Rent received by reason of such reletting shall be
      applied as described below. Also, in any such case, Landlord may change
      the locks or other entry devices of the Premises and make repairs,
      alterations and additions in or to the Premises and redecorate the same to
      the extent deemed by Landlord necessary or desirable and Tenant shall upon
      written demand pay the cost thereof together with Landlord's expenses of
      reletting, including, without limitation, brokerage commissions payable to
      Landlord or Landlord's agent or to others. Landlord may collect

                                       32
<Page>

      the rents from any such reletting and apply the same first to the payment
      of the expenses of reentry, redecoration, repair and alterations and the
      expenses of reletting and second to the payment of Rent, and any excess or
      residue shall operate only as an offsetting credit to reduce the amount of
      Rent due and owing or paid as a result of acceleration or as the same
      thereafter becomes due and payable hereunder; provided that the use of
      such offsetting credit to reduce the amount of Rent due Landlord, if any,
      shall not be deemed to give Tenant any right, title or interest in or to
      such excess or residue and any such excess or residue shall belong to
      Landlord solely. No such reentry, repossession, repairs, alterations,
      additions, or reletting shall be construed as an eviction or ouster of
      Tenant or as an election on Landlord's part to terminate this Lease, or
      shall operate to release Tenant in whole or in part from any of Tenant's
      obligations hereunder unless a written notice of such intention is given
      to Tenant, and Landlord may, at any time and from time to time sue and
      recover judgment for any deficiencies from time to time remaining after
      the application from time to time of the proceeds of any such reletting.

      C.   In the event of the termination of this Lease by Landlord as provided
      for by subparagraph 20.02(B) above, Landlord shall be entitled to recover
      from Tenant all damages and other sums which Landlord is entitled to
      recover under any provision of this Lease or at law or equity, including,
      but not limited to, all the fixed dollar amounts of Rent accrued and
      unpaid for the period up to and including such termination date, as well
      as all other additional sums payable by Tenant, or for which Tenant is
      liable or in respect of which Tenant has agreed to indemnify Landlord
      under any of the provisions of this Lease, which may be then owing and
      unpaid, and all costs and expenses, including without limitation court
      costs and reasonable attorneys' fees incurred by Landlord in the
      enforcement of its rights and remedies hereunder and, in addition, any
      damages provable by Landlord as a matter of law including, without
      limitation, an amount equal to the excess of the Rent provided to be paid
      for the remainder of the term of the Lease over the fair market rental
      value of the Premises (determined at the date of termination of this
      Lease) after deduction of all anticipated expenses of reletting.

      D.   All amounts owed by Tenant to Landlord under this Lease shall be
      deemed additional rent and unless otherwise provided, and (other than the
      Base Rent and Additional Rent which shall be due as provided) shall be
      paid within ten (10) days from the date Landlord renders a statement of
      account therefor to Tenant. All such amounts (including Base Rent and
      Additional Rent) shall bear interest from the date due until the date paid
      at the annual rate of eighteen percent (18%) or at the then maximum legal
      rate of interest, if any, whichever is lower. Tenant shall pay all of
      Landlord's costs, charges and expenses, including without limitation,
      court costs and reasonable attorneys' fees, incurred in enforcing Tenant's
      obligations under this Lease or incurred by Landlord in any litigation,
      negotiation or transaction in which Tenant causes Landlord, without
      Landlord's fault, to become involved or concerned.

      E.   If Tenant shall file for protection under the United States
      Bankruptcy Code now or hereafter in effect, or a trustee in bankruptcy
      shall be appointed for Tenant, Landlord and Tenant agree, to the extent
      permitted by law, to request that the debtor-in-possession or

                                       33
<Page>

      trustee-in-bankruptcy, if one shall have been appointed, either assume or
      reject this Lease within sixty (60) days after such appointment.

20.04 NO REINSTATEMENT. No receipt of money by Landlord from Tenant after the
expiration or termination of this Lease or after the service of any notice or
after the commencement of any suit, or after final judgment for possession of
the Premises, shall reinstate, continue or extend the term of the Lease or
affect any such notice, demand or suit unless expressly agreed to in writing by
Landlord.

20.05 WAIVER. No waiver by Landlord of any default or breach of any covenant by
Tenant hereunder shall be inferred from any omission by Landlord to take action
on account of such default, and no express waiver shall affect any default other
than the default specified in the waiver and then said waiver shall be operative
only for the time and to the extent therein stated. The consent or approval of
Landlord to any act of Tenant shall not be deemed to waive or render unnecessary
Landlord's consent or approval to any subsequent similar acts. No waiver by
Landlord of any provision under this Lease shall be effective unless in writing
and signed by Landlord. Landlord's acceptance of full or partial payment of Rent
during the continuance of any breach of this Lease shall not constitute a waiver
of any such breach of this Lease. Efforts by Landlord to mitigate damages caused
by Tenant's breach of this Lease shall not be construed as a waiver of
Landlord's right to recover damages.

ARTICLE 21 - MISCELLANEOUS

21.01 NO OPTION. Submission of this instrument for examination does not
constitute a reservation of or option for the Premises. The instrument does not
become effective as a lease or otherwise until execution and delivery by both
Landlord and Tenant.

21.02 BROKERS. Tenant and Landlord each hereby represents to the other that it
has dealt directly with and only with the broker or brokers set forth in
Paragraph 1.01 and that it does not know of another broker who negotiated this
Lease or is entitled to any commission in connection herewith. Tenant and
Landlord hereby agree to indemnify, defend (with counsel reasonably acceptable
to the other) and hold the other harmless from and against all losses, damages,
claims, liens, liabilities, costs and expense (including without limitation
reasonable attorneys' fees) arising from any claims or demands of any other
broker or brokers or finders for any commission or other compensation alleged to
be due such broker or brokers or finders in connection with its participating in
the negotiation of this Lease or in exhibiting the Premises on behalf of the
indemnifying party.

21.03 ACCORD AND SATISFACTION. No payment by Tenant of a lesser amount than the
Rent nor any endorsement on any check or letter accompanying any check or
payment as Rent shall be deemed an accord and satisfaction of full payment of
Rent, and Landlord may accept such payment without prejudice to Landlord's right
to recover the balance of such Rent or to pursue other remedies.

21.04 FINANCIAL STATEMENTS. In the event of a proposed sale or other transfer,
financing or refinancing by Landlord of the Building, where the proposed lender
or purchaser requests tenant financial statements, within ten (10) days after
Landlord's request, Tenant shall deliver to Landlord

                                       34
<Page>

the most current year-end financial statements of Tenant and any guarantor of
this Lease, which statements shall have been reviewed or audited by an
independent certified public accountant.

21.05 NOTICE. Except as otherwise herein provided, whenever by the terms of this
Lease notice shall or may be given either to Landlord or to Tenant, such notice
shall be in writing and shall be deemed to have been properly served only if
sent via certified mail return receipt requested, hand-delivery, or by overnight
courier, to the appropriate address set forth in Paragraph 1.01, provided,
however, that either Landlord or Tenant may change the location at which it
receives notices, to another location within the United States of America, upon
not less than ten (10) days notice. Communications delivered by hand or
overnight courier shall be deemed to have been served on the date of receipt.
Mailed communications shall be deemed to have been served at the time the same
were posted plus three (3) business days. Notwithstanding the foregoing, notices
served with respect to emergency matters may be communicated in person or by
telephone.

21.06 EXHIBITS. Reference is made to the Exhibits listed in Paragraph 1.01,
which Exhibits are attached hereto and incorporated herein by reference.

21.07 SURVIVAL. Tenant agrees that its obligations in any provision of this
Lease intended to survive, shall survive the termination of this Lease.

21.08 TENANT'S AUTHORITY. If Tenant signs as a corporation or partnership, each
of the persons executing this Lease on behalf of Tenant does hereby covenant and
warrant that Tenant is a duly authorized and existing entity, that Tenant has
and is qualified to do business in the state in which the Premises are located,
that Tenant has full right and authority to enter into this Lease, and that each
and every person signing on behalf of Tenant is authorized to do so. Upon
Landlord's request, Tenant shall provide Landlord with evidence reasonably
satisfactory to Landlord confirming the foregoing covenants and warranties.

21.09 PERSONS BOUND. The agreements, covenants and conditions of this Lease
shall be binding upon and inure to the benefit of the successors and assigns of
each of the Parties, except that no assignment, encumbrance or subletting by
Tenant, unless permitted by the provisions of this Lease, shall vest any right
in the assignee, encumbrancer or subtenant under such assignment, encumbrance or
subletting.

21.10 PARTIAL INVALIDITY. If any term, covenant, condition or provision of this
Lease, or the application thereof to any person or circumstance, shall to any
extent be declared invalid, unenforceable or in violation of a party's legal
rights, then such term, covenant, condition or provision shall be deemed to be
null and void and unenforceable. However, all other provisions of this Lease, or
the application of such term or provision to persons or circumstances other than
those to which are held invalid, unenforceable or violative of legal rights,
shall not be affected thereby, and each and every other term, condition,
covenant and provision of this Lease shall be valid and be enforced to the
fullest extent permitted by law.

21.11 CAPTIONS. The headings and captions used throughout this Lease are for
convenience and reference only and shall in no way be held to explain, modify,
amplify, or aid in the interpretation,

                                       35
<Page>

construction or meaning of any provisions in this Lease. In the event of any
conflict, inconsistency, or disagreement, the most restrictive Article shall
prevail. The words "Landlord" and "Tenant" wherever used in this Lease shall be
construed to mean plural where necessary, and the necessary grammatical changes
required to make the provisions hereof apply to corporations, limited liability
companies, partnerships, or individuals, men and women, shall in all cases be
assumed as though in each case fully expressed.

21.12 APPLICABLE LAW. This Lease, its interpretation and enforcement shall be
governed by the internal laws of the state in which the Premises are located,
without resort to the choice or conflicts of law provisions of that or any other
state.

21.13 RIGHTS CUMULATIVE. All rights and remedies of Landlord under this Lease
shall be cumulative and none shall exclude any other rights
and remedies allowed by law.

21.14 RECORDATION OF LEASE. Neither Party may record this Lease or a memorandum
thereof without the prior written consent of the other party.

21.15 ENTIRE AGREEMENT. This Lease contains the entire agreement between the
Parties and no modification of this Lease shall be binding upon the Parties
unless evidenced by an agreement in writing signed by Landlord and Tenant after
the date hereof. If there be more than one party comprising Tenant, the
provisions of this Lease shall be applicable to and binding upon all such
tenants jointly and severally.

21.16 WAIVER OF JURY. Landlord and Tenant agree that, to the extent permitted by
law, each shall and hereby does waive trial by jury in any action, proceeding or
counterclaim brought by either against the other on any matter whatsoever
arising out of or in any way connected with this Lease.

ARTICLE 22 - OPTION TO RENEW

      A.   Tenant shall have and is hereby granted one (1) option to renew the
Lease with respect to all (but not less than all) of the Premises for five (5)
years (the "Renewal Term") by notice in writing received by Landlord not less
than nine (9) months prior to the expiration of the then current Term of the
Lease, time being of the essence for the giving of such notice. All of the
covenants, conditions and provisions of the Lease shall be applicable to the
Renewal Term, except that the Annual and Monthly Base Rent shall be adjusted to
the current "Market Rental Rate" for the Premises as of the date the Renewal
Term is to commence with appropriate increases each year thereafter. Landlord
shall advise Tenant of the new monthly rental rate for a Renewal Term within
fifteen (15) days after a request therefore from Tenant; provided however that
Tenant's failure to timely make such request shall not extend the date upon
which Tenant must give notice of its exercise of the option to renew. Landlord's
notification of the new rental may include an escalation to provide for a change
in the fair market rental rate between the time of notification and commencement
of the Renewal Term. In no event shall the Annual and Monthly Base Rent be
subject to determination or modification by any person, entity, court or
authority other than as expressly set forth herein, and in no event shall the
Annual and Monthly Base Rent for the Renewal

                                       36
<Page>

Term be less than the monthly rental during the last year of the current term of
the Lease. Tenant shall have fifteen (15) days from the receipt of Landlord's
notice to either accept or dispute Landlord's determination of the Market Rental
Rate. In the event that Tenant disputes Landlord's determination, Tenant shall
so notify Landlord and advise Landlord of Tenant's determination of the Market
Rental Rate for the Renewal Term. If, after engaging in good faith negotiations,
Landlord and Tenant cannot agree upon the Market Rental Rate within thirty (30)
days of Landlord's receipt of Tenant's original notice of its intent to exercise
its Renewal Option, the "Dispute Resolution Mechanism" described in subparagraph
D below shall apply.

      B.   Tenant's exercise of the foregoing option to renew is subject to the
conditions that (i) the Lease is in full force and effect, (ii) Tenant is not in
default hereunder at the time of notification or at any time after notification
and through commencement of the Renewal Term, (iii) neither the Premises nor any
part thereof have been sublet (other than as permitted under the Lease without
the need for Landlord's consent), (iv) Tenant has not assigned the Lease (other
than as permitted under the Lease without the need for Landlord's consent),
(v) Tenant (or a sublessee or assignee permitted under the Lease without the
need for Landlord's consent) occupies the Premises itself, and (vi) that both at
the time of notification and commencement there has been no material adverse
change in the financial condition of the Tenant since the date of the Lease, as
reasonably determined by Landlord.

      C.   For purposes of this Lease, "Market Rental Rate" shall mean the
rental, as of the date for which such Market Rental Rate is being calculated,
per annum per rentable square foot, for comparable space of comparable size,
which Landlord is offering or prepared to offer in good faith at that time to
third parties for a similar term for such other space in the Building or if no
other comparable space is available in the Building, then for comparable space
in other comparable buildings in the Schaumburg, Illinois office market, taking
into account prevailing market conditions.

      D.   The Dispute Resolution Mechanism shall be as follows: no later than
fifteen (15) days after the end of the 30-day period, Landlord and Tenant shall
jointly appoint as arbitrator a commercial real estate broker licensed in
Illinois with a minimum of ten (10) years experience in the applicable market.
If Landlord and Tenant cannot agree on an acceptable arbitrator, Landlord and
Tenant shall each choose, within an additional fifteen (15) days thereafter, its
own arbitrator who meets the qualifications described above. The arbitrators
shall then jointly select, within an additional ten (10) days, an arbitrator to
serve as the arbitrator hereunder. If either Landlord or Tenant fails to choose
its own arbitrator within said fifteen (15) day period, then the arbitrator
chosen by the other shall resolve the dispute. Within ten (10) days after
appointment (whether mutually by the parties, by default of one party to choose
an arbitrator, or by selection by the two arbitrators), Landlord and Tenant
shall each submit to the arbitrator(s) in writing its good faith estimate of the
Market Rental Rate for the Renewal Term. Within ten (10) days after receipt of
the last of the determinations, the arbitrator(s) shall choose either Landlord's
or Tenants' determination of Market Rental Rate. The cost of the arbitrator(s)
shall be borne by the party whose determination of the Market Rental Rate was
not selected by the arbitrator.

      E.   Landlord shall have no obligation to make improvements, decorations,
repairs, alterations or additions to the Premises as a condition to Tenant's
obligations to pay Rent during the

                                       37
<Page>

Renewal Term unless otherwise agreed to by the parties at the time the amendment
set forth below is executed. In the event that Tenant exercises the renewal
option set forth herein, Tenant agrees to enter into an amendment to the Lease
incorporating the Renewal Term and the Annual and Monthly Base Rent applicable
thereto within thirty (30) days following the exercise of the renewal option,
but in no event shall a delay in the full execution of such amendment nullify
Tenant's exercise of the option to renew.

ARTICLE 23 - TEMPORARY SPACE

            Notwithstanding anything to the contrary contained in this Lease,
during the period of _____, 2001 until the Commencement Date, Tenant will lease
from Landlord on a temporary basis the 6,116 rentable square feet located in
Suite 1200 of the Building (hereinafter referred to as the "Temporary Space"),
which suite is currently subleased by Tenant. All of the terms and conditions of
this Lease shall apply to the lease of the Temporary Space (as if Landlord and
Tenant had entered into a separate lease of the Temporary Space), except that
until such time as the Premises is Substantially Complete, Tenant shall pay Base
Rent and Additional Rent for the Temporary Space at the rental rates for the
Premises as set forth in Paragraph 1.01 above, except that (a) Tenant's right to
use the Temporary Space shall expire on the Commencement Date of this Lease, and
(b) Tenant shall accept the Temporary Space in its current "AS IS" condition.

      IN WITNESS WHEREOF, the parties have signed this Lease as of the date and
year hereinabove set forth.

("Landlord's Work"): (i) paint all existing painted walls in the Premises using
Tenant's choice of Building standard paint and colors; and (ii) remove the
existing carpeting and install new carpet and vinyl base in the entire Premises,
using Tenant's choice of Building standard carpet and colors. Other than as

alter or remodel the Premises. Unless otherwise provided herein, all such
installations shall remain the property of Landlord.

     B.   Landlord shall pay the cost of Landlord's Work. Landlord's Work
shall be completed in a good and workmanlike manner in accordance with
applicable laws. Landlord's Work shall be performed during normal business
hours.

     C.   Landlord shall make a good faith effort to substantially complete
the Landlord's Work not later than the Target Commencement Date set forth in
Paragraph 1.01 of the Lease; provided, however, that the Commencement Date shall
be extended for a period equal to the period of any delay encountered by
Landlord because of Force Majeure (as defined in the Lease), which shall
include, in addition to other named events, vacation of the Premises by existing
tenants, and Tenant Delays.

2.   TENANT'S WORK. Tenant, at its sole cost and expense, shall perform all work
(other than Landlord's Work) as required to put the Premises in a condition to
permit the conduct of Tenant's business therein and in accordance with the
requirements of this Lease. Landlord shall provide Tenant with access to the
Premises as soon as the existing tenant vacates (without obligation for the
payment of Rent until the Commencement Date) for the purpose of permitting
Tenant and/or its contractors to commence installation of Tenant's cabling and
wiring in the Premises. Such improvements shall be performed in accordance with
the terms of this Lease.

3.   COMMENCEMENT DATE. Notwithstanding anything to the contrary stated in this
Lease, the obligations of the Tenant to pay Rent to Landlord as otherwise
provided in this Lease shall not begin or commence until the "Commencement Date"
which for purposes of this Lease shall be the earlier of dates noted below:

     A.   The date when Landlord's Work is substantially completed,
notwithstanding Tenant Delays or a requirement to complete minor corrective
work.

     B.   The date on which the Landlord's Work would have been
substantially completed but for Tenant Delays. For this purpose "Tenant Delays"
shall include, but not be limited to delays caused in whole or in part by:
(i) Tenant's delay in approving materials (e.g. carpet or paint), giving

                                      C-1

authorizations; or (ii) delay in the completion of Tenant's Work; or (iii) any
other delay and/or default on the part of Tenant.

     C.   The date on which Tenant takes occupancy of the Premises, other than
as provided in Paragraph 2 above.

     Notwithstanding anything to the contrary contained in this Lease, if the
installation and operation of the Tenant's telecommunication system is not
complete and operable by the Commencement Date, then the Commencement Date shall
be extended to such date of completion and operation, but in no event later than
January 15, 2002.

4.   MISCELLANEOUS. This Construction Rider is expressly made a part of the
Lease and is subject to each and every term and condition thereof, including,
without limitation, the limitations on liability set forth therein.
