         THIS LEASE AGREEMENT (the "Lease") is made and entered into as of the
Lease Date between Landlord and Tenant. All capitalized terms not otherwise
defined in the body of the Lease have the meanings established in the Lease
Information Summary above.

1.       LEASE GRANT.

         Subject to the terms of this Lease, Landlord leases to Tenant and
Tenant rents from Landlord the Premises in the Building. The Premises are
outlined on the floor plan attached to this Lease as Exhibit A.

2.       TERM.

         2.1.     Commencement Date.

         The term of this Lease (the "Term") will commence on the Commencement
Date and will end on the Termination Date. Upon Tenant's taking occupancy of the
Premises, Landlord and Tenant agree to sign the Certificate of Commencement Date
attached to this Lease as Exhibit G confirming the Commencement Date and the
Termination Date.

         2.2.     Condition of Premises.

                  Tenant's acceptance of possession of the Premises will be
deemed conclusive evidence that Tenant has approved and accepted the Premises in
their "AS-IS" condition on the date Tenant accepts possession. Landlord has no
obligation to make any changes or improvements to the Premises. The cost of any
such changes and/or improvements shall be paid for by Tenant in the manner set
forth in the Workletter attached hereto as Exhibit F, subject to Landlord's
obligation to fund Landlord's Contribution as set forth therein.

         2.3      Tenant's Termination Option.

         Provided an Event of Default is not in existence as of the date of the
Termination Notice and as of the Early Termination Date (as such terms are
defined below), Tenant shall have a one-time option to terminate this Lease (the
"Termination Option") effective on the last day of the sixth (6th) Lease Year
(the "Early Termination Date") by delivering written notice of such termination
(the "Termination Notice") to Landlord not less than the last day of the fifth
(5th) lease year, time being of the essence. Contemporaneously with its delivery
of the Termination Notice, Tenant must also pay to Landlord, by certified or
cashier's check or by wire transfer, a termination fee equal to $1,395,563.00,
(which is the sum of all of Landlord's unamortized costs, including but not
limited to Landlord's unamortized tenant improvements, leasing commissions and
rent abatement (calculated at the rate of 12% per year) as of the Early
Termination Date). In the event Tenant exercises its Termination Option, Tenant
will vacate and surrender possession of the Premises to Landlord on or before
the Early Termination Date in the manner required under this Lease. Any attempt
by Tenant to exercise its Termination Option by any method, at any time or in
any circumstances other than as specifically set forth in this Section 2.3 will
be null and void and of no force or effect at the sole option and discretion of
Landlord. The Termination Option is reserved solely to Tenant and will not inure
to the benefit of any assignees, sublessees, transferees, successors and/or
assigns of Tenant. Notwithstanding any exercise of the Termination Option by
Tenant pursuant to this Section 2.3, (i) Tenant shall remain liable to Landlord
for any and all Base Rent, Additional Rent and/or any other amounts due from
Tenant which accrue prior to the Early Termination Date but which become due on
or after the Early Termination Date, and (ii) Landlord and Tenant shall each
remain liable to the other for the performance of any and all of such party's
respective obligations which accrue prior to the Early Termination Date but
which become due on or after the Early Termination Date.

adjustments set forth in the last sentence of this Section 3.1, the first
monthly installment of Base Rent is due and payable on the Rent Commencement
Date; and subsequently. Base Rent is payable no later than the first day of each
month beginning on the Rent Commencement Date. The monthly Base Rent for any
partial month at the beginning of the Term will equal the product of 1/30 of the
monthly Base Rent in effect during the partial month multiplied by the number of
days in the partial month from and after the Rent Commencement Date.

         3.2.     Additional Rent.

                  (a) Payment of Additional Rent. Commencing on January 1st of
         the calendar year immediately following the Base Year, Tenant will pay

         capital improvements made in order to comply with any law, statute,
         ordinance, code, regulation or insurance requirement(s) promulgated by

         as amortized over the useful economic life of such improvements using

         removal, sweeping and snow removal); (8) legal, accounting, engineering
         and other professional fees and expenses relating to managing and

         of the Building or vacant space in the Building; (7) Taxes; (8) rental
         under any ground leases; (9) cost of repairs, alterations or
         replacements required as the result of the exercise of any right of
         eminent domain, to the extent Landlord has received an award; (10) cost
         of any special service or benefit rendered to a tenant of the Building
         which is not rendered generally to tenants of the Building; (11) costs
         and expenses incurred in connection with leasing space in the Building,
         such as tenant allowances, space planner fees, advertising and
         promotional expenses, and legal fees for the preparation of leases;
         (12) with respect to any leasing office in the Building, rent payable
         in excess of what is reasonable and customary for similar buildings;
         (13) court costs and legal fees incurred in connection with disputes
         with any tenant other than violations of Building rules and
         regulations; (14) costs incurred by reason of the adjudicated violation
         by Landlord of any lease or other contractual obligations; (15)
         Landlord's general overhead, except as it relates to management of the
         Building; (16) payments of any other cost or expense to the extent to

         reimbursements of Operating Costs and Taxes from tenants in the
         Building); (17) costs of paintings, sculptures and other art work
         within the Building; (18) any compensation paid to any person or entity
         controlled directly or indirectly by Landlord or any principal of
         Landlord but only to the extent such compensation exceeds what would
         have been earned had such services, supplies or materials been provided
         on a competitive basis; (19) costs (including, without limitation,
         attorneys' fees), fines or penalties incurred due to the adjudicated
         violation by Landlord of applicable laws and regulations; and (20) all

         and/or maintenance of the Building systems which costs for routine
         repairs and/or maintenance will not exceed $20,000 in any calendar
         year).

                  (d) Definition - Taxes. The term "Taxes" means all taxes,
         assessments and governmental charges payable in a calendar year,
         regardless of when such Taxes become a lien upon the Building,
         including but not limited to all real estate and transit district taxes
         and assessments, sewer charges, sales and use taxes, ad valorem taxes,
         personal property taxes, the Illinois Property Replacement Tax and any
         other taxes and assessments attributable to the Building (or its
         operation), the grounds, parking areas, driveways, and alleys around
         the Building, but excluding any federal and state taxes on the income
         of Landlord from the operation of the Building and excluding
         inheritance, estate, succession, transfer, gift, franchise or capital
         stock taxes, nor shall Taxes include any interest or penalties on
         account of Landlord's failure to pay such Taxes in a timely manner. If
         the present method of taxation changes so that in lieu of the whole or
         any part of any Taxes, there is levied on Landlord a capital tax
         directly on the rents received solely from the Building or a franchise
         tax, assessment, or charge based, in whole or in part, upon such rents
         for the Building, then all such taxes, assessments, or charges, or the
         part of such taxes so based, will be deemed to be included within the
         term "Taxes" for purposes of this Lease. Notwithstanding anything in
         this Section 3.2 to the contrary, for purposes of computing the Tax
         Adjustment, the Taxes shall be determined based on a Class 5a
         commercial property under the Cook County Classification Ordinance (or
         successor legislation).

                                       3

                  (e) Payment of Additional Rent. Landlord will make a good
         faith estimate of the Additional Rent to be due from Tenant for all or
         part of any calendar year during the Term, and Tenant agrees to pay to
         Landlord, on the January 1, 2007 and on the first day of each
         subsequent calendar month during the Term, an amount equal to 1/12th of
         the estimated Additional Rent for such full or partial calendar year.
         From time to time, Landlord may estimate and re-estimate the Additional
         Rent to be due from Tenant and deliver a copy of the estimate or
         re-estimate to Tenant. Subsequently, the monthly installments of
         Additional Rent payable by Tenant will be appropriately adjusted in
         accordance with Landlord's estimations so that by the end of the
         calendar year in question Tenant will have paid all of the Additional
         Rent as estimated by Landlord. By April 1 of each calendar year, or as
         soon after that date as practicable, Landlord will furnish to Tenant a
         statement of Operating Costs paid for the previous year, adjusted as
         provided in Section 3.2(f) below (the "Operating Costs Statement"). By
         September 1 of each calendar year, or as soon after that date as
         practicable, Landlord will furnish to Tenant a statement of the Taxes
         paid for the previous year, adjusted as provided in Section 3.2(f)
         below (the "Tax Statement"). If the Operating Costs Statement and/or
         the Tax Statement reveal(s) that Tenant paid more in Operating Costs
         Adjustment or Tax Adjustment than the actual amount for the year for
         which such statement was prepared, then Landlord will promptly credit
         Tenant for such excess. Likewise, if Tenant paid less in Operating
         Costs Adjustment than the actual amount for the year for which such
         statement was prepared, then Tenant shall pay such deficiency to
         Landlord within thirty (30) days after Landlord's invoice. This
         provision will survive the Termination Date of this Lease.

                  (f) Occupancy Adjustment. With respect to any calendar year or
         partial calendar year in which the Building is not fully occupied
         (including without limitation the Base Year), those Operating Costs
         (including management fees) which vary with occupancy of the Building
         for such period will, for the purposes of this Lease, be increased to
         the amount which would have been incurred had the Building been fully
         occupied.

                  (g) Operating Costs Adjustment - Sears Lease As of the date of
         this Lease, Sears Roebuck & Co. ("Sears") leases approximately 248,376
         rentable square feet of space (the "Retail Space") in the Building.
         During the Term, except as provided herein, total Operating Costs will
         be reduced by the annual amount set forth on Exhibit H attached to this
         Lease (the "Retail Contribution"). The Retail Contribution covers a
         portion of the Operating Costs (the "Sears Operating Costs") for water,
         management fees, administrative fees and insurance, being the services
         (the "Sears Services") which Landlord is, as of the date of this Lease,
         obligated to furnish to Sears under the Sears Lease. Any other services
         or requirements needed by Sears to operate the Retail Space are paid by
         Sears. Landlord further agrees that if in the future Landlord provides
         additional services (other than the Sears Services) to Sears or any
         other retail occupant of the Retail Space, then the cost of such
         additional services will not be included in Operating Costs. In
         addition, if following the expiration of the Sears Lease, the Retail
         Space is used for office purposes rather than retail purposes, the
         parties will make an equitable adjustment (on a proportionate basis) to
         (i) the Retail Contribution, (ii) Tenant's Proportionate Share -
         Operating Costs, (iii) the Base Year Operating Costs, and (iv) any
         other item(s) requiring an adjustment as a result of such conversion;
         provided, however, that in no event will any such adjustment result in
         Tenant paying any more or less, on a per square foot basis, than what
         Tenant would have paid had the Sears Lease not expired.

<PAGE>

                  (h) Tenant's Right to Review Operating Costs and Tax
         Computations. If Tenant takes exception to the calculation of the
         Operating Costs for any calendar year of the Term, including the
         applicable Base Year, for a period of six (6) months after receipt of
         the applicable Operating Costs Statement, Tenant shall have the right
         to examine and audit the records supporting such calculations. Tenant
         agrees that it may not withhold any payments or offset any amounts
         against Rent in connection with any such examination and review.
         Further, Tenant may engage the services of any consultant to make its
         own review of Landlord's calculation of Operating Costs. The cost of
         Tenant's consultant shall be borne solely by Tenant except as set forth
         below. If Landlord and Tenant agree or if there is a judicial
         determination that the Operating Costs have been overstated by
         Landlord, then Landlord shall recalculate the Operating Costs
         Adjustment, as applicable, and pay to Tenant any overpayment. If
         Landlord and Tenant agree or if there has been a judicial determination
         that the Operating Costs have been overstated by more than 5%, Landlord
         shall also pay the reasonable actual cost of Tenant's consultant,
         provided Tenant uses a third party non-affiliated consultant which
         bills for its services on a non-contingent basis.

                  (i) Landlord agrees that it will not collect more than one
         hundred percent (100%) of the increases in Operating Costs and Taxes
         (as such terms are defined and applicable under this Lease and under
         the leases in the Building for other tenants) from Tenant and all other
         tenants in the Building.

         3.3.     Payment.

         Tenant agrees to timely pay to Landlord during the Term Base Rent,
Additional Rent and all additional sums to be paid by Tenant to Landlord under
this Lease (collectively the "Rent"), without, except as otherwise set forth in
this Lease, notice, demand, abatement, deduction, setoff or counterclaim, at
Landlord's Address for Payment of Rent or as otherwise specified by Landlord.
Tenant further agrees to pay a late fee equal to five percent (5%) of any
delinquent payment to reimburse Landlord for its cost and inconvenience incurred
as a consequence of Tenant's delinquency. Notwithstanding anything above to the
contrary, Tenant will not be obligated to pay a late fee for the first two (2)
delinquent payments in any calendar year, if such payment (or payments) is (are)
received within ten (10) days of the due date. In no event, however, will the
charges permitted under this Section 3.3 or elsewhere in this Lease, to the
extent they are considered to be interest under law, exceed the maximum lawful
rate of interest. Notwithstanding anything above to the contrary, Tenant will
not be obligated to pay a late fee for the first two (2) delinquent payments in
any calendar year, if such payment (or payments) is (are) received within five
(5) days of the due date.

4.       SECURITY DEPOSIT.

         4.1.     Letter of Credit.

         Tenant will deliver to Landlord, simultaneously with the execution of
this Lease, a letter of credit (the "Letter of Credit") in the amount of the
Security Deposit as security for the prompt, full and faithful performance by
Tenant of the terms and provisions of this Lease. Landlord will have no
obligation to pay any interest on the Security Deposit to Tenant. The Security
Deposit is not an advance payment of Rent nor a measure or limit of Landlord's
damages upon an Event of Default (as defined in Section 15 below). The Letter of
Credit is subject to the following provisions:

                  (a) Form and Issuer. The Letter of Credit must (i) be a clean,
         unconditional, stand-by, irrevocable Letter of Credit in favor of
         Landlord in a form which is acceptable to Landlord in all respects (ii)
         bear an effective date substantially the same as the date of this
         Lease, and (iii) be issued by Wachovia Bank or by a federally insured
         national banking association located in Chicago, Illinois which is
         reasonably acceptable to Landlord in all respects.

                                       5
<PAGE>

                  (b) Expiration; Extension or Replacement. The Letter of Credit
         must: (i) have an expiration date no earlier than the Termination Date
         of this Lease, or (ii) be renewed annually through the Termination
         Date, in which event Tenant must submit to Landlord original amendments
         extending the Letter of Credit expiration date (or replacement Letters
         of Credit with extended expiration dates), on an annual basis no later
         than thirty (30) days prior to the expiration date of the Letter of
         Credit then in effect. Failure to so extend the expiration date of the
         Letter of Credit in the foregoing manner will, in addition to all of
         Landlord's other remedies, entitle Landlord to draw down the Letter of
         Credit without notice to Tenant and to hold or apply the proceeds as
         provided in this Lease.

                  (c) Draws. If there shall occur an Event of Default under this
         Lease, Landlord may but is not obligated to draw down on all or a
         portion of the Letter of Credit without notice to Tenant and apply the
         proceeds to the payment of any sum owing or any other sum which
         Landlord may be required or deems necessary to spend or incur by reason
         of such Event of Default. If Landlord draws upon the Letter of Credit
         and any portion of the proceeds of such draw is not required for such
         purposes, Landlord will treat such unused proceeds as a cash security
         deposit, as security for the full and prompt performance by Tenant of
         the terms and covenants of this Lease and apply the same as provided in
         Section 4.1 above. Following any such application of the Security
         Deposit as described above, Tenant agrees to pay to Landlord on demand
         the amount so applied in order to restore the Security Deposit to its
         original amount or restore the Letter of Credit in an amount equal to
         the amount drawn. Provided that Tenant has performed all of its
         obligations under this Lease, Landlord will, within thirty (30) days
         after the end of the Term, return the Security Deposit or Letter of
         Credit to Tenant. If Landlord transfers its interest in the Premises
         and the transferee assumes Landlord's obligations under this Lease,
         then Landlord will assign the Security Deposit to the transferee and
         Landlord subsequently will have no further liability for the return of
         the Security Deposit. In such event, Tenant agrees to cooperate with
         Landlord and take all reasonable actions necessary to effectuate the
         assignment of the Security Deposit to the transferee.

         4.2.     INTENTIONALLY DELETED

5.       LANDLORD'S OBLIGATIONS.

         5.1.     Services.

         Landlord will furnish to the Premises (1) water at those points of
supply provided for general use of tenants of the Building; (2) heating and air
conditioning between 8:00 a.m. and 6:00 p.m. on weekdays and from 8:00 a.m. to
1:00 p.m. on Saturdays (collectively "Normal Business Hours"); (3) janitorial
service to the Premises on weekdays, other than holidays, for Building-standard
installations as set forth on Exhibit C, and such window washing as may from
time to time be reasonably required (but not less than two (2) times per
calendar year for exterior window washing, weather permitting); (4) passenger
elevators for ingress and egress, provided that Landlord may reasonably limit
the number of operating elevators during hours which are not Normal Business
Hours; and (5) electrical current for Tenant's equipment in a sufficient
quantity to meet Normal Office Usage (as defined below), provided that Tenant
will be responsible for the cost of any additional electrical requirements

                                       6
<PAGE>

beyond Normal Office Usage. In a manner comparable to other renovated Class B
office buildings of similar age and type in the "Loop" area of downtown Chicago,
Landlord will (i) maintain the common areas, systems, and equipment servicing
the Building in reasonably good order and condition, and (ii) provide building
security services. If Tenant desires any heating or air conditioning at any time
other than during Normal Business Hours, then such services will be supplied to
Tenant upon the written request (including an email notice from authorized
Tenant personnel) of Tenant delivered to Landlord not less than twenty-four (24)
hours prior to the business day for which such extra usage is required and prior
to 3:00 P.M. on the business day immediately preceding any weekend day or
holiday for which such extra service is required. Notwithstanding the provisions
set forth in the immediately preceding sentence, Landlord will use commercially
reasonable efforts to provide heating or air-conditioning for extra usage on a
business day if written request is received prior to 3:00 P.M. on such business
day. Tenant, upon demand from Landlord, will pay Landlord for such services at
rates determined by Landlord from time to time (it being acknowledged that such
rate is currently $150.00 per hour per floor). Landlord and Tenant acknowledge
that Tenant has access to the Building twenty-four (24) hours a day, seven (7)
days a week.

         5.2.     Utilities.

         Since the respective utilities are not separately metered at the
Premises and billed directly to Tenant by the service provider, Tenant will pay
directly to Landlord as Rent, upon demand by Landlord, the cost of all utilities
used or consumed at, on or in the Premises. Such cost will be the actual cost
(with no profit or markup) to Landlord based upon Tenant's usage evidenced by
the submeters servicing the Premises. Such meters will be read by Landlord on a
periodic basis. If at any time in the future the respective utilities are
separately metered at the Premises and billed directly by the service provider,
then Tenant shall pay directly to each provider of such utilities the cost of
all utilities used or consumed at, on or in the Premises as and when the charges
for the same become due and payable. If Tenant fails to pay for any of the above
services when the same become due and payable, then, provided Landlord has given
Tenant not less than ten (10) days prior notice, Landlord will have the right
but not the duty to pay the same, which amount so paid will be deemed Rent and
will be payable immediately upon demand from Landlord. Tenant agrees to (i) keep
and cause to be kept closed all windows in the Premises, (ii) at all times
reasonably cooperate with Landlord in the operation of the heating and air
conditioning systems, and (iii) abide by all reasonable regulations and
requirements which Landlord may prescribe to permit the proper functioning and
protection of the heating and air conditioning systems.

         5.3.     Excess Utility Use.

         Landlord is not required to furnish electrical current for equipment
whose electrical energy consumption exceeds Normal Office Usage (as defined
below). If Tenant's requirements for or consumption of electricity exceed 7
watts/rsf for receptacle and lighting ("Normal Office Usage"), Landlord will, at
Tenant's expense, make reasonable efforts to supply such service through the
then-existing feeders and risers serving the Building and the Premises, and
Tenant agrees to pay to Landlord the cost of such service within thirty (30)
days after Landlord has delivered to Tenant an invoice for such services.
Landlord may determine the amount of such additional consumption and potential
consumption by any verifiable method, including installation of a separate meter
in the Premises installed, maintained, and read by Landlord, at Tenant's
expense. Tenant may not install any electrical equipment requiring special
wiring or requiring voltage in excess of Normal Office Usage unless approved in
advance and in writing by Landlord, which approval will be within Landlord's
sole discretion. Tenant agrees not to use electricity in the Premises which
exceeds the capacity of existing feeders and risers to or wiring in the
Premises. If approved by Landlord, any risers or wiring required to meet
Tenant's excess electrical requirements will be installed by Landlord, upon

                                       7
<PAGE>

Tenant's request and at Tenant's cost, if, in Landlord's judgment, the same are
necessary and will not cause permanent damage to the Building or the Premises,
cause or create a dangerous or hazardous condition, entail excessive or
unreasonable alterations, repairs, or expenses, or interfere with or disturb
other tenants of the Building. If Tenant uses machines or equipment in the
Premises which affect the temperature otherwise maintained by the air
conditioning system or otherwise overload any utility, Landlord may install
supplemental air conditioning units or other supplemental equipment in the
Premises, and such cost, including the cost of installation, operation, use, and
maintenance, will be paid by Tenant to Landlord within thirty (30) days after
Landlord has delivered to Tenant an invoice for such cost. The costs, if any,
for which Tenant is responsible under this Section 5.3 will be at Landlord's
actual cost without profit or mark up.

         5.4.     Restoration of Services.

                  Landlord agrees to use reasonable efforts to restore any
service that becomes unavailable. Such unavailability will not, however, render
Landlord liable for any damages, be a constructive eviction of Tenant,
constitute a breach of any implied warranty, or entitle Tenant to any abatement
of Tenant's obligations under this Lease. . Notwithstanding any provision to the
contrary in this Lease, if there is a cessation, interruption or reduction of
any of the services agreed to be furnished by Landlord under this Section 5 and
if (a) the same does not arise as a result of an act or omission of Tenant, (b)
as a result, the Premises, or any portion of the Premises are rendered
Untenantable (as defined below), and (c) such Untenantability continues without
interruption for a period of five (5) consecutive days after Tenant has notified
Landlord, then the Rent payable under this Lease shall be equitably abated, to
the extent of such Untenantability until the Premises are no longer
Untenantable. The foregoing abatement of Rent shall become effective as of the
first business day following the day on which Tenant gave notice to Landlord
that the Premises became Untenantable. "Untenantable" and "Untenantability"
means that the entire Premises are not occupied by Tenant in the normal course
of its business, except that the Premises shall not be deemed untenantable if
there are present in the Premises a limited number of employees of Tenant who
are performing activities such as securing the Premises and removing files and
computers.

5.5.     Chilled Water Usage.

         Tenant has elected to utilize chilled water for supplemental
air-conditioning equipment. At Tenant's sole cost, Landlord shall either (i)
install a BTU meter to measure the usage of chilled water, such measurement to
be made in ton hours or (ii) change Tenant a flat fee per ton per month for its
water usage. In the event Tenant elects subparagraph (i) above, Tenant will
permit necessary access to the Premises and Landlord will take meter readings on
a monthly basis and Tenant further agrees to pay $0.36 per ton hour for its
actual chilled water usage. Within thirty (30) days after receipt from Landlord
of the calculation of the cost of the monthly ton hour usage, Tenant will pay
Landlord such amount as calculated by Landlord.

         5.6      Landlord's Representations.

         Landlord represents as follows:

                  (a) Landlord has received no notice that the Building,
         including its common areas, is not in general compliance with the
         requirements of the Americans With Disabilities Act.

                  (b) Landlord has received no notice of any violation of any
         environmental law applicable to the Building.

                                       8

6.       IMPROVEMENTS; ALTERATIONS; REPAIRS; MAINTENANCE.

         6.1.     Improvements; Alterations.

         The provisions of this Section 6.1 shall apply to improvements and
alterations contemplated subsequent to the tenant improvements described in the
Workletter. No alterations, physical additions or improvements in or to the
Premises may be made without Landlord's prior written consent which consent
shall not unreasonably be withheld. Landlord may withhold its consent to any
alteration or addition that could affect the Building's structure or its HVAC,
plumbing, electrical or mechanical systems. Tenant may not paint or install
lighting, signs, window or door lettering, or advertising media of any type on
or about the Premises in a location visible from outside the Premises without
the prior written consent of Landlord. Tenant acknowledges that Landlord may
withhold its consent to any such painting or installation which could affect the
appearance of the exterior of the Building or of any common areas of the
Building. All alterations, additions and improvements installed in the Premises
must be (i) performed at Tenant's expense and only in accordance with plans and
specifications which have been previously submitted to and approved in writing
by Landlord, and (ii) constructed, maintained and used by Tenant at its own risk
and expense in accordance with all laws. Landlord's approval of the plans and
specifications is not a representation by Landlord that such alterations,
additions, or improvements comply with any law. Prior to commencing any work,
Tenant agrees to reimburse Landlord for the actual out-of-pocket costs incurred
to third parties by Landlord in connection with supervising such alterations,
additions or improvements performed by Tenant subsequent to the tenant
improvements described in the Workletter. Tenant agrees that it will remove or
cause its contractor(s) to remove all waste and debris from the Premises upon
the completion of any alterations, additions or improvements. Notwithstanding
anything in this Section 6.1 to the contrary, Landlord's consent will not be
required if (i) the alterations do not affect the HVAC, plumbing, electrical or
mechanical systems of the Building, (ii) the alterations do not affect the
structure of the Building, (iii) the cost of the alterations do not exceed
$15,000 in any six (6) month period and (iv) Tenant has notified Landlord of
such alterations prior to commencement of any work.

         6.2.     Repairs and Maintenance.

         Tenant agrees to maintain the Premises in a clean, safe, and operable
condition, and will not permit or allow to remain any waste or damage to any
portion of the Premises. Tenant agrees to pay for the cost of repairing or
replacing, subject to Landlord's direction and supervision, any damage to the
Premises and the Building caused by Tenant, Tenant's employees, Tenant's
transferees, or their respective agents, contractors, or invitees. If Tenant
fails to commence such repairs or replacements within fifteen (15) days after
the occurrence of such damage, then Landlord may make the same at Tenant's cost.
If any such damage occurs outside of the Premises, then Landlord may elect to
repair such damage at Tenant's expense, rather than having Tenant repair such
damage. The cost of all repair or replacement work performed by Landlord under
this Section 6.2 must be paid by Tenant to Landlord, together with a supervisory
and administrative fee equal to ten percent (10%) of the cost of the repair or
replacement work performed by Landlord, within thirty (30) days after Landlord
has invoiced Tenant for such cost and will constitute Rent under this Lease.
Notwithstanding anything in this Section 6.2 to the contrary, in the event
Landlord recovers any insurance proceeds for the costs of any repairs made
pursuant to this Section 6.2, Landlord will reimburse Tenant to the extent
Tenant has paid such costs.

         6.3.     Performance of Work.

         Only Landlord or contractors and subcontractors approved in writing by
Landlord (which approval shall not unreasonably be withheld, conditioned or
delayed) may perform the work described in this Section 6. Tenant will cause all
contractors and subcontractors to procure and maintain insurance coverage naming
Landlord as an additional insured against such risks, in such amounts, and with
such companies as Landlord may reasonably require. All such work must be
performed in accordance with all applicable governmental requirements and in a
good and workmanlike manner so as not to damage the Premises, the Building or
the components of the Building. Tenant agrees to defend, indemnify and hold
Landlord, its trustees, beneficiaries, employees, successors and assigns
harmless from and against any claims, liabilities, damages, losses, costs and
expenses, including but not limited to attorney's fees and court costs, suffered
or incurred by Landlord arising from any of Tenant's alterations, additions or
improvements to the Premises, except to the extent caused by the negligence or
willful misconduct of Landlord, its agents or employees.

         6.4.     Mechanic's Liens.

         Tenant must not permit any mechanic's lien(s) to be filed against the
Premises or the Building for any work performed, materials furnished, or
obligations incurred by or at the request of Tenant. If such a lien is filed,
then, within ten (10) days after Landlord has delivered notice of the filing to
Tenant, Tenant must either pay the amount of the lien or diligently contest such
lien and deliver to Landlord a bond or other security reasonably satisfactory to
Landlord. If Tenant fails to timely take either such action, then Landlord may
pay the lien claim, and any amounts so paid, including expenses and interest,
will constitute Rent payable by Tenant to Landlord within thirty (30) days after
Landlord has invoiced Tenant for such payment. Tenant agrees to defend,
indemnify and hold Landlord, its trustees, beneficiaries, employees, successors
and assigns harmless from and against any claims, liabilities, damages, losses,
costs and expenses, including but not limited to attorney's fees and court
costs, suffered or incurred by Landlord arising from the presence or removal of
any mechanic's lien(s) affecting the Premises and/or the Building relating to
any work performed, materials furnished or obligations incurred by or at the
request of Tenant.

7.       USE.

         Tenant may use the Premises only for the Permitted Use, and must comply
with all applicable statutes, laws, ordinances, codes, orders, rules and
regulations, as well as all requirements (of which Tenant has been provided
notice) of any of Landlord's insurance providers, relating to the use, condition
and occupancy of the Premises. The Premises may not be used for any use which
(i) is disreputable, creates fire hazards, or results in an increased rate of
insurance on the Building or its contents; (ii) would violate any covenant,
agreement, term, provision or condition of this Lease or is in contravention of
the certificate of occupancy or zoning ordinances pertaining to the Building;
(iii) would serve any foreign, federal, state, county, municipal or other
governmental entity or agency that either (a) regularly attracts to its premises
large numbers of persons in the general public (e.g., without limitation,
Immigration and Naturalization Service, Social Security Administration) or (b)
creates security risks to Building tenants materially greater than risks caused

                                       10
<PAGE>

by general office tenants (e.g., Bureau of Alcohol, Tobacco and Firearms, U. S.
Marshall, Federal Bureau of Investigation); (iv) would alter, affect or
interfere with or would overload the electrical, mechanical or HVAC systems or
any other component of the Building, or would exceed the floor load per square
foot which the floor was designed to carry and which is allowed by law; or (v)
would, in Landlord's reasonable judgment, in any way adversely impair or tend to
impair or exceed the design criteria, structural integrity, character,
reputation or appearance of the Building. Tenant will not conduct or permit the
generation, transportation, storage, installation, treatment or disposal, either
in the Building or in the Premises, of any hazardous or toxic materials (other
than materials which are used in the operation of common office machines or
equipment or in cleaning the office and are properly and lawfully stored), and
Tenant will keep the Building and the Premises free of any lien or claim imposed
under any federal, state or local environmental statute, law, ordinance, code,
rule or regulation. If, because of Tenant's acts, the rate of insurance on the
Building or its contents increases, Tenant must pay to Landlord the amount of
such increase on demand. Tenant agrees to conduct its business and control its
agents, employees, and invitees in such a manner as not to create any nuisance
or unreasonably interfere with other tenants or Landlord in its management of
the Building.

8.       ASSIGNMENT AND SUBLETTING.

         8.1.     Transfers; Consent.

                  (a) Transfers. Tenant may not, without the prior written
         consent of Landlord, which consent may be granted or withheld by
         Landlord in its reasonable discretion, do any of the following:

                           (i) assign, transfer, or encumber this Lease or any
                  estate or interest in this Lease, whether directly or by
                  operation of law;

                           (ii) permit any other entity to become Tenant under
                  this Lease by merger, consolidation, or other reorganization;
                  provided, however, Tenant does not need to obtain Landlord's
                  consent if, after giving effect to such merger, consolidation
                  or other reorganization, Tenant maintains fifty percent (50%)
                  of the ownership in or voting control of such new entity and
                  the minimum tangible net worth of such new entity is the same
                  as that of Tenant at the beginning of this Lease;

                           (iii) if Tenant is an entity other than a corporation
                  whose stock is publicly traded, permit the transfer of an
                  ownership interest in Tenant so as to result in a change in
                  the current control of Tenant (except as otherwise provided in
                  Section 8.1(d) below);

                           (iv) sublet any portion of the Premises;

                           (v) grant any license, concession or other right of
                  occupancy of any portion of the Premises; or

                           (vi) permit the use of the Premises by any parties
                  other than Tenant.

                  Any of the events listed in Section 8.1(a)(i) through
         8.1(a)(vi) above are referred to as a "Transfer".

                  Without limitation as to Landlord's right to reasonably
         withhold its consent, by way of example, Landlord may withhold its
         consent to a Transfer if Tenant's proposed transferee (1) is a tenant
         in the Building whose space needs can otherwise be accommodated by
         Landlord, in Landlord's reasonable discretion; (2) is not of good
         reputable character; (3) does not have the financial wherewithal to pay
         to Tenant its sublease rent and perform all of Tenant's obligations
         under this Lease; (4) does not intend to use the Premises only for the
         Permitted Use; (5) creates security risks to the Building Tenants
         materially greater than risks caused by general office tenants (e.g.
         Bureau of Alcohol, Tobacco and Firearms, U.S. Marshall, and Federal
         Bureau of Investigation); or (6) is a foreign, federal, state, county,
         municipal or other governmental entity.

                                       11
<PAGE>

                  (b) Procedure to Obtain Consent. If Tenant requests Landlord's
         consent to a Transfer, then Tenant must provide Landlord with a written
         description of all terms and conditions of the proposed Transfer,
         copies of the proposed documentation, and the following information
         about the proposed transferee: name and address; reasonably
         satisfactory information about its business and business history; its
         proposed use of the Premises; banking, financial, and other credit
         information that Landlord may request; and general references
         sufficient to enable Landlord to determine the proposed transferee's
         creditworthiness and character. Landlord will provide Tenant with a
         written response to such Transfer request within thirty (30) days after
         Landlord's receipt of Tenant's written request. Concurrently with
         Tenant's request for consent to a Transfer, Tenant agrees to (i) pay to
         Landlord an assignment fee in the amount of One Thousand and 00/100
         Dollars ($1,000.00), and (ii) reimburse Landlord immediately upon its
         request for all of its expenses (including but not limited to
         reasonable attorneys' fees and administrative fees) incurred in
         connection with considering any request for consent to a Transfer.
         Nothing in this Section 8.1(b) may be construed as granting to any
         third party the rights of a third-party beneficiary, so as to entitle
         such third party to seek to enforce any of the above provisions.

                  (c) Obligations After Transfer. If Landlord consents to a
         proposed Transfer, then both Tenant and the proposed transferee must
         (i) deliver to Landlord a written agreement acceptable in all respects
         to Landlord under which the proposed transferee expressly assumes all
         of Tenant's obligations under this Lease, and (ii) if requested by
         Landlord, execute the consent form required by Landlord. Landlord's
         consent to a Transfer will not release Tenant from its obligations
         under this Lease, but rather Tenant and its transferee will be jointly
         and severally liable for such obligations. Landlord's consent to any
         Transfer does not waive Landlord's rights as to any subsequent
         Transfers. If an Event of Default occurs while the Premises or any part
         of the Premises are subject to a Transfer, then Landlord, in addition
         to its other remedies, may collect rent due and owing directly from
         such transferee and apply such rent against Rent. Tenant authorizes its
         transferees to make payments of rent directly to Landlord upon receipt
         of notice from Landlord to do so.

                  (d) Permitted Transfers. Notwithstanding anything this Section
         8 to the contrary, Tenant shall have the right, without Landlord's
         consent, to assign this Lease or sublease the Premises to, or allow
         occupancy of the Premises by a parent corporation of Tenant or an
         affiliated corporation of Tenant or any entity which controls, is
         controlled by, or is under common control with Tenant, provided Tenant
         is not released or discharged from any disability or obligation under
         this Lease and further provided Tenant gives Landlord prior written
         notice of such Transfer. In addition, provided Tenant notifies Landlord
         prior to any Transfer described in Sub-section 8.1(a)(iii) above, such
         Transfer may be made without Landlord's prior consent as long as the
         tangible net worth of Tenant, as newly constituted, or the new entity,
         as the case may be, is equal to or greater than the tangible net worth
         of Tenant on the Commencement Date.

         8.2.     Recapture.

         In the event Tenant causes or seeks to cause a Transfer (other than a
Permitted Sublease, as defined below), Landlord may terminate this Lease and
recapture the applicable space as of the date the proposed Transfer is to be
effective, or within thirty (30) days after the date of Landlord's discovery of
the Transfer, as the case may be. Landlord may exercise this termination right
within thirty (30) days after Landlord's receipt of Tenant's written request for
Landlord's consent, or within thirty (30) days after learning of such Transfer
if Landlord's consent has not been requested by Tenant. If Landlord terminates
this Lease as provided above, then this Lease will cease and Tenant shall pay to

                                       12
<PAGE>

Landlord all Rent accrued through the Termination Date. Subsequently, Landlord
may lease the Premises to the prospective transferee (or to any other person)
without liability to Tenant. Notwithstanding anything above to the contrary, if
Landlord exercises its right to recapture, then Tenant may, within five (5) days
following receipt of Landlord's notice to exercise its right of recapture,
rescind its request regarding such Transfer; provided, however, that any such
rescission may only be invoked two (2) times during the Term. "Permitted
Sublease" means a sublease (i) entered into by Tenant prior to three (3) years
before the Termination Date, (ii) subleasing less than 25,000 square feet of the
Premises and (iii) expiring not later than two (2) years before the Termination
Date.

         8.3.     Additional Compensation.

         Tenant agrees to pay to Landlord, immediately upon receipt, fifty
percent (50%) any and all funds received by Tenant for a Transfer in excess of
the Rent allocable to the Premises after Tenant has first recovered its
reasonable out-of-pocket transfer costs, if any, including, but not limited to,
tenant improvements costs, leasing commissions, free rent and other monetary
concessions granted to the transferee in the Transfer.

         8.4      Intentionally Deleted.

9.       INSURANCE; WAIVERS; SUBROGATION; INDEMNITY.

         9.1.     Insurance.

         Tenant agrees to maintain throughout the Term the following insurance
         policies:

                  (a) comprehensive general liability insurance in amounts of
         not less than a combined single limit of $3,000,000.00 or such other
         amounts as Landlord may, from time to time, reasonably require, and
         consistent with that required of similar tenants in similar office
         buildings, insuring Tenant, Landlord, Landlord's agents and their
         respective affiliates against all liability for injury to or death of a
         person or persons or damage to property arising from the use and
         occupancy of the Premises;

                  (b) insurance covering the full value of Tenant's property and
         improvements, and other property (including property of others) in the
         Premises;

                  (c) contractual liability insurance sufficient to cover
         Tenant's indemnity obligations under this Lease;

                  (d) worker's compensation insurance, containing a waiver of
         subrogation endorsement acceptable to Landlord; and

                  (e) business interruption insurance.

         Tenant will, prior to taking possession of the Premises and prior to
the commencement of any work in the Premises, furnish Landlord with certificates
of such insurance and such other evidence satisfactory to Landlord confirming
Tenant's maintenance of all insurance coverages required under this Lease and
naming Landlord and any other parties requested by Landlord as additional
insured(s), provided such other parties would customarily be named as an
additional insured on insurance maintained by an office tenant in a similar
class office building. Each certificate must contain a written obligation on the
part of each insurance company to notify Landlord at least thirty (30) days
before cancellation or a material change of any such insurance policies. All
such insurance policies must be (i) issued by insurers authorized to do business
in the State of Illinois and which are rated at least A-VIII in Best's Key
Rating Guide, and (ii) issued by companies and be in form and substance
reasonably satisfactory to Landlord. The term "affiliate" means any person or
entity, directly or indirectly, controlling, controlled by, or under common
control with the party in question. Tenant acknowledges and agrees that it is
not permitted to self-insure under this Lease except for workers compensation
insurance.

                                       13
<PAGE>

         9.2.     Landlord Insurance

         Landlord shall maintain the following insurance at all times, until the
expiration of the Term:

                  (a) Physical Damage Insurance including, but not limited to,
        fire, sprinkler leakage, vandalism and all other risks of direct
        physical loss as insured against under special broad form coverage
        endorsement for the full replacement cost of the Building. Such
        insurance shall be written on an "all risks" of physical loss or damage
        basis, for the full replacement cost value of the Building and in
        amounts that meet any coinsurance clause of the policies of insurance.

                  (b) Commercial General Liability Insurance (with broad form
        commercial liability endorsement, including contractual liability
        insurance and bodily injury liability) with respect to the Building and
        land covering, without limitation, any liability for bodily injury,
        personal injury, including death and property damage with limits at
        least equal to those required to be carried by Tenant.

         9.3.     Waiver of Negligence; No Subrogation.
         Landlord and Tenant each waives any claim it might have against the
other for damage to or theft, destruction, loss, or loss of use of any property
(a "Loss"), to the extent the same is insured against under any insurance policy
that covers the Building, the Premises, Landlord's or Tenant's fixtures,
personal property, leasehold improvements, or business, or with respect to such
matters as are required to be insured against under the terms of this Section 9,
regardless of whether the negligence of the other party caused such loss.
Landlord's waiver under this Section 9.2 will not, however, include any
deductible amounts on insurance policies carried by Landlord nor any coinsurance
penalty which Landlord may sustain. Each party will cause its insurance carrier
to endorse all applicable policies waiving the carrier's rights of recovery
under subrogation or otherwise against the other party.

         9.4.     Indemnity by Tenant.

         Except to the extent such loss is caused by the negligence or willful
misconduct of Landlord or is covered (or is required to be covered under this
Lease) by Landlord's or Tenant's applicable insurance, Tenant agrees to defend,
indemnify and hold Landlord, its trustees, beneficiaries, employees and agents
harmless from and against all claims, demands, liabilities, causes of action,
suits, judgments, and expenses (including attorneys' fees) for any loss arising
from (i) any occurrence on the Premises and/or the Building caused by or
contributed to by Tenant, its subtenants, licensees, employees, invitees,
contractors and/or agents (collectively "Tenant's Affiliates"), and (ii)
Tenant's or any of Tenant's Affiliates' failure to perform its obligations under
this Lease. This indemnity provision will survive the termination or expiration
of this Lease.

         9.5.     Indemnity by Landlord.

         Except to the extent such loss is covered (or is required to be covered
under this Lease) by Landlord's or Tenant's applicable insurance, Landlord shall
protect, indemnify and save Tenant and its officers, agents and employees
harmless from and against any and all obligations liabilities, costs, damages,
claims and expenses including attorneys fees for any loss arising from (i)
Landlord's failure to perform its obligations under this Lease, or (ii) the
negligence or willful misconduct of Landlord, its agents, contractors, servants,
employees or invitees, during the Term. This indemnity provision will survive
the termination or expiration of this Lease.

                                       14

10.      SUBORDINATION; ATTORNMENT; NOTICE TO LANDLORD'S MORTGAGEE.

         10.1.    Subordination.

         Subject to the provisions of this Section 10.1, this Lease is
automatically subordinate to any deed of trust, mortgage, or other security
instrument, or any ground lease, master lease or primary lease, that now or
subsequently covers all or any part of the Building without any further action
or writing of the parties (the mortgagee under any such mortgage or the lessor
under any such lease is referred to below as a "Landlord's Mortgagee"). In
addition, Tenant agrees to execute and deliver to the requesting party a written
agreement confirming any such subordination to any present or future Landlord's
Mortgagee; provided Landlord shall have furnished to Tenant a non-disturbance
agreement from such Landlord's Mortgagee (specifically excluding lessors under
ground leases existing on the date of this Lease) in the customary form then in
use by Landlord's Mortgagee. Any Landlord's Mortgagee may at any time
unilaterally elect to make this Lease superior to its mortgage, ground lease or
other interest in the Premises by so notifying Tenant in writing. Not later than
sixty (60) days after the execution of this Lease, and as a condition to
Tenant's agreement to subordinate to the current Landlord's Mortgagee, Landlord
shall deliver to Tenant a non-disturbance agreement from the current Landlord's
Mortgagee (and specifically excluding current lessors under ground leases
existing on the date of this Lease) in the form customarily in use by Landlord's
Mortgagee.

         10.2.    Attornment.

         Tenant agrees to attorn to any party succeeding to Landlord's interest
in the Premises, whether by purchase, foreclosure, deed in lieu of foreclosure,
power of sale, attornment, termination of lease, or otherwise. Within ten (10)
business days after such party's request, Tenant will execute and deliver to the
requesting party a written agreement(s) confirming such attornment.

         10.3.    Notice to Landlord's Mortgagee.

         Tenant may not seek to enforce any remedy it may have for any default
on the part of the Landlord without first giving written notice by certified
mail, return receipt requested, specifying the default in reasonable detail, to
any Landlord's Mortgagee whose address has been given to Tenant, and affording
such Landlord's Mortgagee a reasonable opportunity to perform Landlord's
obligations under this Lease.

11.      RULES AND REGULATIONS.

         Tenant must comply with the rules and regulations of the Building which
are attached as Exhibit B. Landlord may, from time to time, change such rules
and regulations for the safety, care, or cleanliness of the Building and related
facilities, provided that such changes will not unreasonably interfere with
Tenant's use of the Premises. Tenant is responsible for the compliance with such
rules and regulations by its employees, agents, and invitees. Landlord agrees
that any revisions to or enforcement of the rules and regulations will be
uniform and nondiscriminatory as to all tenants in the Building. In the event of
any conflict between the provisions of this Lease and the rules and regulations
of the Building, the provisions of this Lease will govern.

                                       15
<PAGE>

12.      CONDEMNATION.

         12.1.    Total Taking.

         If the entire Building or Premises is taken by right of eminent domain
or conveyed in lieu of eminent domain (a "Taking"), this Lease will terminate
and Rent will be apportioned as of the date of the Taking, and Tenant will have
no claim against Landlord for the value of the unexpired Term.

         12.2.    Partial Taking -- Tenant's Rights.

         If any part of the Building becomes subject to a Taking and such Taking
will prevent Tenant from conducting its business in the Premises in a manner
reasonably comparable to that conducted immediately before such Taking for a
period of more than one hundred eighty (180) days, then Tenant may terminate
this Lease as of the date of such Taking by giving written notice to Landlord
within thirty (30) days after the Taking, and Rent will be apportioned as of the
date of such Taking. If Tenant does not terminate this Lease, then Rent will
abate on a basis reasonably determined by Landlord as to that portion of the
Premises rendered untenantable by the Taking.

         12.3.    Partial Taking -- Landlord's Rights.

         If any material portion but less than all of the Building becomes
subject to a Taking and Landlord makes a good faith determination that (i) such
Taking will prevent Tenant from conducting its business in the Premises in a
manner reasonably comparable to that conducted immediately before such Taking
for a period of more than one hundred eighty (180) days, (ii) restoring the
Premises would be uneconomical, (iii) the condemnation award is insufficient to
rebuild or restore the Building or the Premises, or (iv) Landlord is required to
pay any condemnation award arising from the Taking to any Landlord's Mortgagee,
then Landlord may terminate this Lease by delivering written notice to Tenant
within thirty (30) days after such Taking, and Rent will be apportioned as of
the date of such Taking. If Landlord does not so terminate this Lease, then this
Lease will continue, but if any portion of the Premises has been taken, Rent
will abate as provided in the last sentence of Section 12.2 above.

         12.4.    Award.

         If any Taking occurs, then Landlord is entitled to receive the entire
award or other compensation for the land on which the Building is situated, the
Building, and other improvements taken, and Tenant may separately pursue a claim
against the condemnor for the value of Tenant's personal property which Tenant
is entitled to remove under this Lease (but because of the condemnation is
unable to move such property), the portion of Tenant's leasehold improvements
not paid for by Landlord, moving costs, and other claims it may have so long as
such claim does not diminish Landlord's award. In no event may Tenant seek or
file any claim against Landlord.

13.      FIRE OR OTHER CASUALTY.

         13.1.    Landlord's Rights.

         If all or any part of the Building and/or the Premises is (are) damaged
by fire or other casualty (a "Casualty") then, subject to Landlord's rights to
terminate set forth below, Landlord shall repair and restore the damaged
portions of the Building and the Premises to its or their condition prior to the
Casualty, as further set forth in Section 13.2 below, with reasonable
promptness, subject to reasonable delays for insurance adjustments and delays
caused by matters beyond Landlord's reasonable control, but Landlord shall not
be obligated to expend an amount in excess of the proceeds awarded pursuant to
the applicable insurance policy or policies. Within sixty (60) days after the
date of the Casualty, (such date referred to as the "Casualty Determination

                                       16

Date"), Landlord shall make a reasonable good faith determination of whether (i)
the Premises and/or the Building can be restored within one hundred eighty (180)
days of the Casualty Determination Date and (ii) whether more than fifty percent
(50%) of the rentable square footage of the Building, including the Premises,
has been destroyed or rendered untenantable by the Casualty. If Landlord
reasonably determines that the Premises cannot be rebuilt within such one
hundred eighty (180) day period or that more than fifty percent (50%) of the
Building are so destroyed or untenantable as set forth in the preceding
sentence, then either Landlord or Tenant may terminate this Lease by giving the
other party written notice ("Casualty Termination Notice") of such election to
terminate within twenty (20) days following the Casualty Determination Date, and
Base Rent and Additional Rent will equitably abate to the extent of the Casualty
as of the date of the Casualty. Such termination shall be effective sixty (60)
days after the Casualty Termination Notice.

         If the Premises or the Building are damaged by a Casualty during the
last fifteen (15) months of the Term, and there is an option period remaining
under Section 23 below, and if Tenant exercises such option, then Landlord shall
proceed in accordance with the provisions of the immediately preceding
paragraph. If the Premises or the Building are damaged by a Casualty during the
last fifteen (15) months of the Term, and there is no option period remaining
under Section 21.21 below, or if an option period remains and Tenant does not
exercise its option to extend, then if Landlord or Tenant makes a reasonable
good faith determination that restoring the Premises would be uneconomical, or
Landlord, in reasonably good faith, determines that (i) there are insufficient
insurance proceeds to rebuild or restore the Building or the Premises, or (ii)
Landlord is required to pay any insurance proceeds arising out of the Casualty
to any Landlord's Mortgagee, then either Landlord or Tenant may terminate this
Lease by giving the other party written notice of such election to terminate
(the "Second Casualty Termination Notice") within sixty (60) days after the
Casualty has occurred (the "Second Casualty Termination Date"), and Base Rent
and Additional Rent will equitably abate to the extent of the Casualty as of the
date of the Casualty. Such termination shall be effective sixty (60) days after
the date of the Second Casualty Termination Notice.

         13.2.    Repair Obligation.

         If Landlord and Tenant both elect not to terminate this Lease following
a Casualty, then Landlord, within a reasonable time after such Casualty, will
proceed with reasonable diligence to repair, restore or rehabilitate the
Building and/or the Premises, as the case may be, to substantially the same
condition as they existed immediately before such Casualty. However, Landlord
will not be required to repair or replace any of the furniture, equipment,
fixtures, and other leasehold improvements which may have been placed by or at
the request of Tenant or other occupants in the Building or the Premises and
required to be insured by Tenant or other tenants, and Landlord's obligation to
repair or restore the Building and/or the Premises will be limited to the extent
of the insurance proceeds actually received by Landlord for the Casualty in
question. In the event that the insurance proceeds actually received or to be
received by Landlord do not or will not permit Landlord to repair, restore or
rehabilitate the Premises and/or the Building, as the case may be, to
substantially the same condition as they were before such Casualty, then
Landlord will notify Tenant at such time as it reasonably believes that such

                                       17
<PAGE>

repair, restoration or rehabilitation will not be completed to such condition,
and within thirty (30) days of receipt of such notice, Tenant will have the
right to terminate this Lease, and Base Rent and Additional Rent will abate as
of the date of the Casualty. During such repair or rebuilding of the Building
and/or the Premises, Rent for the portion of the Premises rendered untenantable
by the damage will be abated from the date of damage until the completion of the
repair, restoration or rehabilitation. In the event that Landlord and Tenant
both elect not to terminate the Lease and Landlord proceeds to repair the
Building and/or the Premises and, the restoration of the Building and/or the
Premises is not substantially complete on or before three hundred sixty (360)
days from the Casualty Determination Date, Tenant may terminate this Lease by
giving Landlord notice of such election (the "Repair Period Tenant Termination
Notice"), and Base Rent and Additional Rent will abate as of the date of the
Casualty. Such termination shall be effective on the date of the Repair Period
Tenant Termination Notice.

14.      PERSONAL PROPERTY TAXES.

         Tenant is liable for all taxes based upon this Lease or the receipt of
Rent due under this Lease and all taxes levied or assessed against any personal
property, furniture or fixtures placed by Tenant in the Premises. If any taxes
for which Tenant is liable are levied or assessed against Landlord or Landlord's
property and Landlord elects to pay the same, or if the assessed value of
Landlord's property is increased by inclusion of such personal property,
furniture or fixtures and Landlord elects to pay the taxes based on such
increase, then Tenant shall pay to Landlord as Rent, upon demand, the part of
such taxes for which Tenant is primarily liable under this Lease. Landlord may
not, however, pay such amount if Tenant notifies Landlord that it will contest
the validity or amount of such taxes before Landlord makes such payment, and
subsequently diligently proceeds with such contest in accordance with law and if
the non-payment does not pose a threat of lien or other cloud on Landlord's
title to the Building, or threat of loss or seizure of the Building or interest
of Landlord in the Building.

15.      DEFAULT.

         15.1.    Events of Default.

         Each of the following occurrences will constitute an "Event of
Default":

                  (a) Tenant's failure to pay Rent on or before the date when
         due; provided, however, not more than two (2) times in any calendar
         year during the Term, Landlord agrees to give Tenant notice of such
         failure and Tenant shall have five (5) days from such notice to cure
         such failure to pay Rent;

                  (b) Tenant's failure to perform, comply with or observe any
         other agreement or obligation of Tenant under this Lease and the
         continuance of such failure for a period of more than thirty (30) days
         after Landlord has delivered written notice thereof to Tenant;
         provided, however, if the breach cannot be reasonably cured within such
         thirty (30) day period so long as Tenant is diligently proceeding to
         cure such breach, then the thirty (30) day period shall be extended for
         such additional time as may be reasonably necessary, but in no event in
         excess of one hundred twenty (120) days;

                  (c) The filing of a petition by or against Tenant (the term
         "Tenant" includes, for the purpose of this Section 15(c), any guarantor
         of the Tenant's obligations under this Lease) (1) in any bankruptcy or
         other insolvency proceeding; (2) seeking any relief under any state or
         federal debtor relief law; (3) for the appointment of a liquidator or
         receiver for all or substantially all of Tenant's property or for
         Tenant's interest in this Lease; or (4) for the reorganization or
         modification of Tenant's capital structure. If, however, such a
         petition is filed against Tenant, then such filing will not be an Event
         of Default unless Tenant fails to have the proceedings initiated by
         such petition dismissed within sixty (60) days after such filing;

                                       18
<PAGE>

                  (d) The failure by Tenant to take initial possession of and
         initially occupy the Premises in accordance with the terms of this
         Lease;

                  (e) The failure of any guarantor(s) of this Lease to comply
         with the terms and conditions of its(their) guaranty; and

                  (g) Any Event of Default under the Other Lease (as defined in
         Section 21.24 below).

         15.2.    Default Interest.

         All past due Rent and any other payments required of Tenant under this
Lease will be deemed Rent and interest will accrue from the date due until paid
at the rate of interest equal to two percent (2%) over the corporate base rate
or so-called "prime rate" as announced from time to time by JP Morgan Chase
Corporation.

16.      REMEDIES.

         Upon any Event of Default, Landlord may, at its election, in addition
to all other rights and remedies afforded Landlord under this Lease or by law or
equity, take any one or more of the following actions:

         16.1.    Right To Terminate.

         Upon the occurrence of an Event of Default, Landlord has the right to
terminate the Lease and obtain possession of the Premises. Landlord may make its
election to terminate known to Tenant by delivery of a notice of termination.
Such termination is immediately effective and Landlord, if necessary, is
entitled to commence immediately an action in summary proceedings to recover
possession of the Premises.

         16.2.    Receipt Of Money After Termination.

         No receipt of money by Landlord from Tenant after the termination of
this Lease shall act to reinstate, continue or extend the Term, nor affect or
waive any notice given by Landlord to Tenant prior to such receipt of money.

         16.3.    Recovery Of Damages.

         Landlord agrees to use commercially reasonable efforts to mitigate
damages caused by a default or breach of Tenant. If Landlord terminates this
Lease at any time for any breach, then in addition to any other remedies it may
have, Landlord may recover from Tenant by reason of such breach all Rent accrued
and unpaid for the period up to and including such termination date, as well as
all other additional sums payable by Tenant under this Lease. In addition,
Landlord may recover as damages for loss of the bargain and not as a penalty the
sum of (i) the aggregate sum which at the time of such termination represents
the excess, if any, of the present value of the aggregate Rent and Additional
Rent at the same annual rate for the remainder of the Term as then in effect
over the then present value of the then aggregate fair rental value of the
Premises for the balance of the Term immediately prior to such termination, such
present worth to be computed in each case on the basis of a five percent (5%)
per annum discount from the respective dates upon which Rent would have been
payable under this Lease had the Term not been terminated, and (ii) any
additional damages, including any reasonable costs or expenditures to fit the
Premises to the needs of Tenant and any other reasonable costs as provided in
this Lease or permitted under applicable law.

                                       19
<PAGE>

         16.4.    Right To Re-Enter.

         If the Event of Default is the nonpayment of Rent, Landlord may, as an
alternative to terminating the Lease, serve a written demand for possession or
payment. Unless the Rent is paid in accordance with the demand for possession or
payment, Landlord is entitled to possession of the Premises and Tenant will then
have no further right to possession under the Lease. Tenant remains liable to
Landlord for the payment of all Rent and other charges which Tenant has agreed
to pay under this Lease throughout the remainder of its Term. If Landlord elects
to re-enter, as provided, it may from time to time, without terminating this
Lease, make such alterations and repairs as may be necessary in order to relet
the Premises, and relet all or any part of such Premises for such term or terms
(which may be for a term extending beyond the Term of this Lease) and at such
rental or rentals and upon such other terms and conditions as Landlord in its
reasonable discretion may deem advisable. Upon each such reletting all rentals
and other sums received by Landlord from such reletting are applied, first, to
the payment of any indebtedness other than rent due under this Lease from Tenant
to Landlord; second, to the payment of any costs and expenses of such reletting,
including reasonable brokerage fees and attorneys' fees and costs of such
alterations and repairs; third, to the payment of Rent and other charges due
from Tenant, and the residue, if any, will be held by Landlord and applied in
payment of future rent as the same may become due and payable. If such rentals
and other sums received from such reletting during any month are insufficient to
pay the Rent and other charges due from Tenant, Tenant agrees to pay such
deficiency to Landlord. Such deficiency will be calculated and paid monthly. No
such re-entry or taking possession of such premises by Landlord may be construed
as an election on its part to terminate this Lease. Notwithstanding any such
reletting without termination, Landlord may at any time elect to terminate this
Lease for such previous breach.

         16.5.    Independent Covenant.

         Tenant acknowledges and agrees that its obligation to pay Rent under
this Lease is an independent covenant and that such obligation to pay Rent is
not subject to setoff or recoupment in connection with any action for summary
proceedings to recover possession of the Premises.

         16.6.    Legal Expenses.

         If Landlord or Tenant is required to bring an action arising out of the
covenants, terms, conditions or provisions of this Lease, or if Landlord
undertakes an action for summary proceedings to recover possession of the
Premises, the prevailing party will be reimbursed by the other party for such
reasonable costs and attorneys' fees as the prevailing party may incur in
connection with such action.

17.      PAYMENT BY TENANT; NON-WAIVER.

         17.1.    Payment by Tenant.

         Upon any Event of Default, Tenant agrees to pay to Landlord all costs
incurred by Landlord (including court costs and reasonable attorneys' fees and
expenses not covered under Section 16.6 above) in (1) obtaining possession of
the Premises, (2) removing and storing Tenant's or any other occupant's
property, (3) repairing, restoring, altering, remodeling, or otherwise putting
the Premises into condition acceptable to a new tenant, (4) if Tenant is
dispossessed of the Premises and this Lease is not terminated, reletting all or
any part of the Premises (including brokerage commissions, cost of tenant finish
work, and other costs incidental to such reletting), (5) performing Tenant's
obligations which Tenant failed to perform, and (6) enforcing its rights,
remedies and recourses arising out of the Event of Default or in obtaining
advice about the same. To the full extent permitted by law, Landlord and Tenant
agree the federal and state courts of the state in which the Premises and
Building are located have exclusive jurisdiction over any matter relating to or
arising from this Lease and the parties' rights and obligations under this
Lease.

                                       20
<PAGE>

         17.2.    No Waiver.

         Landlord's acceptance of any payment from Tenant following an Event of
Default will be deemed Rent and will not waive Landlord's rights regarding such
Event of Default. No waiver by Landlord or Tenant of any violation or breach by
the other of any term(s) contained in this Lease will waive such party's rights
regarding any future violation of such term(s). Landlord's acceptance of any
partial payment of Rent will not waive Landlord's rights with regard to the
remaining portion of the Rent that is due, regardless of any endorsement or
other statement on any instrument delivered in payment of Rent or any writing
delivered in connection with such Rent. Accordingly, Landlord's acceptance of a
partial payment of Rent will not constitute an accord and satisfaction of the
full amount of the Rent that is due.

18.      SURRENDER OF PREMISES.

         No act by Landlord will be deemed an acceptance of a surrender of the
Premises, and no agreement to accept a surrender of the Premises will be valid
unless it is in writing and signed by Landlord (except that no such writing
shall be required upon the surrender of the Premises at the scheduled
Termination Date). At the expiration or termination of this Lease, Tenant must
deliver to Landlord the Premises with all improvements in good repair and
condition, broom-clean, except for reasonable wear and tear (and condemnation
and Casualty damage, as to which Sections 12 and 13 above control). All
alterations, additions, improvements, equipment, wiring and furniture (other
than the initial tenant improvements constructed pursuant to the Workletter
which Tenant shall not be required by Landlord to remove) made in or upon the
Premises (for which Landlord has requested removal at the time of Landlord's
consent) must, at Landlord's option upon notice to Tenant, either be removed by
Tenant (and Tenant must repair all damage caused by such removal) or remain on
the Premises without compensation to Tenant. Tenant must also deliver to
Landlord all keys to the Premises. So long as Tenant has performed all of its
obligations under this Lease, Tenant may remove all unattached trade fixtures
and personal property placed in the Premises by Tenant, provided that Tenant
remains obligated to repair all damage caused by such removal. All items not so
removed will be deemed to have been abandoned by Tenant and may be appropriated,
sold, stored, destroyed, or otherwise disposed of by Landlord without notice to
Tenant and without any obligation to account for such items. The provisions of
this Section 18 will survive the end of the Term.

19.      HOLDING OVER.

         If Tenant fails to vacate the Premises at the end of the Term, then
Tenant will be a tenant-at-will and, in addition to all other damages and
remedies to which Landlord may be entitled for such holding over, Tenant must
pay to Landlord a monthly Base Rent for all or any part of a month equal to 150%
of the aggregate Base Rent plus all other Rent payable during the last month of
the Term. Tenant is also responsible for all damages (exclusive of consequential
damages), incurred or sustained by Landlord by reason of such retention,
together with all costs incurred by Landlord (including but not limited to
reasonable attorneys' fees) in connection with such holdover. In addition, if
Tenant's holdover continues for sixty (60) days or more, Landlord may elect,
upon notice to Tenant, that such holding over will constitute a renewal of this
Lease for one (1) year from the date of Landlord's notice, at the stated
holdover rate, but acceptance by Landlord of Rent after such termination will
not in and of itself constitute a renewal. Nothing contained in this Section 19,
however, will be construed or operate as a waiver of Landlord's right of
re-entry or any other right of Landlord.

                                       21

20.      CERTAIN RIGHTS RESERVED BY LANDLORD.

         Landlord reserves the following rights which may be exercised without
notice (except as otherwise expressly provided below) and without liability to
Tenant for damage or injury to property, person or business, and without
effecting an eviction or disturbance of Tenant's use or possession of the
Premises, nor giving rise to any claim for setoff or abatement of Rent or
affecting any of Tenant's obligations under this Lease:

                  (a) To decorate and to make inspections, repairs, alterations,
         additions, changes, or improvements, whether structural or otherwise,
         in and about the Building during ordinary business hours, and if Tenant
         desires to have such work done during other than business hours, Tenant
         agrees to pay all overtime and additional expenses resulting from such
         work; to enter upon the Premises with prior reasonable notice and,
         during the continuance of any such work, to temporarily close doors,
         entryways, public space, and corridors in the Building; and to
         interrupt or temporarily suspend Building services and facilities
         agreed to be furnished by Landlord, all without the same constituting
         an eviction of Tenant in whole or in part and without abatement of Rent
         by reason of loss or interruption of the business of Tenant or
         otherwise and without in any manner rendering Landlord liable for
         damages or relieving Tenant from the performance of Tenant's
         obligations under this Lease, except as otherwise provided in Section
         5.4; provided, however, reasonable access to the Premises will be
         maintained and the business of Tenant may not be interfered with
         unreasonably;

                  (b) To change the name and street address of the Building, and
         to change the arrangement and location of entrances or passageways,
         doors, and doorways, corridors, elevators, stairs, restrooms or other
         public parts of the Building, but not those lying exclusively within
         the Premises;

                  (c) To take such reasonable measures as Landlord deems
         advisable for the security of the Building and its occupants; including
         evacuating the Building for cause, suspected cause, or for drill
         purposes; temporarily denying access to the Building; and closing the
         Building after normal business hours and on Sundays and holidays,
         subject, however, to Tenant's right to enter when the Building is
         closed after normal business hours under such reasonable regulations as
         Landlord may prescribe from time to time for application to and for the
         benefit and protection of all tenants of the Building;

                  (d) Upon prior oral notice (which shall be given a reasonable
         amount of time in advance except for emergencies) to Tenant, to enter
         the Premises during reasonable hours (i) at any time during the Term to
         show the Premises to prospective purchasers or lenders, or (ii) during
         the last twelve (12) months of the Term to show the Premises to
         prospective tenants, and to decorate, remodel, repair, alter or
         otherwise prepare the Premises for reoccupancy at any time after Tenant
         abandons the Premises;

                  (e) Upon prior written notice to Tenant, and limited to only
         one (1) occasion during the Term, to relocate Tenant within the
         Building to new space (the "Relocation Space") which is comparable in
         size, utility and condition to the Premises. Such relocation will be
         effective on a date specified by Landlord, which date will not be less
         than ninety (90) days after Landlord's notice. If Landlord relocates
         Tenant, Landlord will (i) cause the physical relocation move to occur
         in an evening or over a weekend but only between January 16 and October
         31, (ii) give Tenant an allowance sufficient to cover Tenant's
         reasonable costs to reconstruct the Relocation Space to a standard

                                       22
<PAGE>

         substantially similar to the Premises on the date of the relocation,
         (iii) cause the Relocation Space to be located on the 11th floor of the
         Building or higher (so long as the Relocation Space is located on a
         floor with substantially the same functionality and useable square
         footage), (iv) pay all other reasonable out-of-pocket costs related to
         the relocation (i.e. stationary and printed material, computer and
         telephone relocation etc). Upon such relocation, the Relocation Space
         will be deemed to be the Premises, the terms of the Lease will remain
         in full force and apply to the Relocation Space, and Landlord and
         Tenant agree to execute an amendment to this Lease confirming such
         relocation of Tenant to the Relocation Space within twenty (20) days
         after Tenant takes possession of the Relocation Space;

                  (f) To maintain within the lobby of the Building a directory
         containing a standard listing with Tenant's name and such other
         listings reasonably required by Tenant;

                  (g) To install and maintain signs on the exterior and interior
         of the Building;

                  (h) To prescribe and approve in advance the location and style
         of any suite number and identification sign or lettering on the door to
         the Premises occupied by Tenant, the cost of which signage shall be
         borne by Tenant;

                  (i) To retain at all times and to use in appropriate instances
         pass keys to the Premises;

                  (j) To grant to anyone the right to conduct any business or
         render any service in the Building, whether or not it is the same as or
         similar to the use expressly permitted to Tenant in Section 7 above;

                  (k) To have access for Landlord and other tenants of the
         Building to all mail chutes according to the rules of the United States
         Post Office;

                  (l) To enter the Premises at any time for reasonable purposes,
         including supplying janitor service or other service to be provided to
         Tenant under this Lease; and

                  (m) To require all persons entering or leaving the Building
         during such hours as Landlord may from time to time determine to
         identify themselves to watchmen or security personnel by registration
         or otherwise, and to establish their right to enter or leave the
         Building; provided Landlord will not be liable in damages for any error
         with respect to admission to or eviction or exclusion of any person
         from the Building. In case of fire, invasion, insurrection, mob, riot,
         civil disorder, public excitement or other commotion, or threat
         thereof, Landlord reserves the right to limit or prevent access to the
         Building during the continuance of same, shut down elevator service,
         activate elevator emergency controls, or otherwise take such action or
         preventive measures deemed necessary by Landlord for the safety of the
         tenants or other occupants of the Building or the protection of the
         Building and the property in the Building. Tenant agrees to cooperate
         in any reasonable safety program developed by Landlord.

21.      MISCELLANEOUS.

         21.1.    Landlord Transfer.

         Landlord may transfer any portion of the Building and any of its rights
under this Lease. If Landlord assigns its rights under this Lease, then Landlord
will be released from any further obligations under this Lease, provided that
the assignee assumes Landlord's obligations under this Lease in writing.

                                       23
<PAGE>

         21.2.    Landlord's Liability.

         The liability of Landlord and Landlord's Affiliates (as defined below)
to Tenant for any default by Landlord under the terms of this Lease will be
recoverable only from the interest of Landlord in the Building, and Tenant
agrees to look solely to Landlord's interest in the Building for the enforcement
of any judgment, award, order or other remedy under or in connection with this
Lease. Under no circumstances will Landlord or Landlord's Affiliates have any
personal liability for any of the foregoing matters. The term "Landlord's
Affiliates" means collectively Landlord's property manager and its and
Landlord's respective current and future affiliates, trustees, beneficiaries,
principals, investors, directors, officers, general or limited partners,
shareholders, managers, employees, agents, representatives, successors and
assigns.

         21.3.    Force Majeure.

         Other than for Tenant's obligations under this Lease which can be
performed by the payment of money (e.g., payment of Rent and maintenance of
insurance), whenever a period of time is prescribed for action to be taken by
either party, such party will not be liable or responsible for, and there will
be excluded from the computation of any such period of time, any delays due to
strikes, riots, acts of God, shortages of labor or materials, war, governmental
laws, regulations, or restrictions, or any other causes of any kind whatsoever
which are beyond the reasonable control of such party.

         21.4.    Brokerage.

         Tenant has not dealt with any broker or agent in connection with the
negotiation or execution of this Lease, other than Landlord's Broker and
Tenant's Broker, whose commissions are payable by Landlord. Landlord's
commission obligation to Tenant's Broker is One Hundred Fifty-Thousand Dollars
($150,000). Tenant agrees to defend, indemnify and hold Landlord harmless from
and against all claims, damages, costs, expenses, attorneys' fees and other
liabilities for commissions or other compensation claimed by Tenant's Broker or
any other broker or agent.

         21.5.    Estoppel Certificates.

                  (a) From time to time, Tenant agrees to furnish to Landlord,
         Landlord's Mortgagee or any third party designated by Landlord, within
         ten (10) business days after Landlord has made a request, a written
         estoppel certificate signed by Tenant or an authorized signatory of
         Tenant in a form customarily used by Landlord's Mortgagee or other
         third party designated by Landlord, confirming and certifying to such
         party, as of the date of such estoppel certificate, to the extent
         factual or known, (i) that Tenant is in possession of the Premises,
         (ii) that this Lease is unmodified and in full force and effect (or if
         there have been modifications, that this Lease is in full force and
         effect as modified and setting forth such modification); (iii) that
         Tenant has no offsets, claims or defenses against Rent or the
         enforcement of any right or remedy of Landlord, or any duty or
         obligation of Tenant under this Lease (and, if so, specifying the same
         in detail); (iv) the dates through which Base Rent and Additional Rent
         have been paid; (v) that Tenant has no knowledge of any then uncured
         defaults on the part of Landlord under this Lease (or if Tenant has
         knowledge of any such uncured defaults, specifying the same in detail);
         (vi) that Tenant having made due investigation has no knowledge of any
         event having occurred that authorizes the termination of this Lease by
         Tenant (or if Tenant has such knowledge, specifying the same in
         detail): (vii) the amount of any Security Deposit held by Landlord;
         (viii) that there are no actions, whether voluntary or otherwise,
         pending against Tenant; and (ix) other matters reasonably requested by
         Landlord or such other party. If Tenant fails to deliver the estoppel
         certificate described above within such ten (10) business day period,
         Landlord shall make a second request to Tenant for the estoppel
         certificate. Notwithstanding anything in this Lease to the contrary, if
         Tenant fails to deliver the estoppel certificate within ten (10)
         business days after the second request, then, in addition to any other
         remedies Landlord may have under this Lease, Tenant acknowledges and
         agrees that Landlord is authorized to act as Tenant's attorney-in-fact
         to execute the estoppel certificate on behalf of Tenant, and Tenant
         will be bound by the terms of the estoppel certificate prepared and
         executed by Landlord. Tenant's authorization of Landlord to act as
         Tenant's attorney-in-fact under this Section 21.6 will be exclusively
         for the purpose of executing the estoppel certificate described above.

                  (b) From time to time, but no more frequently than one (1)
         time in any twelve (12) month period, Landlord agrees to furnish to
         Tenant or any third party designated by Tenant, within ten (10)
         business days after Tenant has made a request, a written estoppel
         certificate signed by Landlord or an authorized signatory of Landlord,
         confirming and certifying to such party, as of the date of such
         estoppel certificate, to the extent factual or known, (i) that the
         Lease is in full force and effect, (ii) the dates to which Rent has
         been paid, (iii) that neither Landlord nor Tenant is in default in the
         performance of the Lease nor has either such party committed any breach
         of the Lease, nor has notice of default been given by one party to the
         other, (iv) the Lease constitutes the only agreement between Landlord
         and Tenant with respect to the Premises, and the Lease has not been
         amended, modified or superseded.

         21.6.    Notices.

         21.7.    Severability.

         If any clause or provision of this Lease is illegal, invalid or
unenforceable under present or future laws, then the remainder of this Lease
will not be affected, and in lieu of such clause or provision, a clause or
provision as similar in terms to such illegal, invalid or unenforceable clause
or provision will be deemed added to this Lease as may be possible and be legal,
valid, and enforceable.

         21.8.    Amendments; Binding Effect.

         This Lease may not be amended except by instrument in writing signed by
Landlord and Tenant. No provision of this Lease will be deemed to have been
modified or waived by Landlord unless such modification or waiver is in writing
signed by Landlord. No custom or practice which may evolve between the parties
in the administration of the terms of this Lease will waive or diminish the
right of Landlord to insist upon the performance by Tenant in strict accordance
with the terms of this Lease, except as expressly modified in writing signed by
Landlord and Tenant. The terms and conditions contained in this Lease will inure
to the benefit of and be binding upon the parties, and upon their respective
successors in interest and legal representatives, except as otherwise expressly
provided. This Lease is for the sole benefit of Landlord and Tenant, and, other
than Landlord's Mortgagee, no third party may be deemed a third party
beneficiary.

         21.9.    Quiet Enjoyment.

         Provided Tenant has performed all of its obligations under this Lease,
Tenant may peaceably and quietly hold and enjoy the Premises for the Term,
without hindrance from Landlord or any party claiming by, through, or under
Landlord, subject to the terms and conditions of this Lease.

         21.10.   No Merger.

         No merger of the leasehold estate created under this Lease with the fee
estate in all or any part of the Premises will occur if the same person acquires
or holds, directly or indirectly, this Lease or any interest in this Lease and
the fee estate in the leasehold Premises or any interest in such fee estate.

         21.11.   No Offer.

         The submission of this Lease to Tenant may not be construed as an
offer, and Tenant will have no rights under this Lease unless Landlord executes
a copy of this Lease and delivers it to Tenant.

         21.12.   Entire Agreement; Governing Law.

         This Lease constitutes the entire agreement between Landlord and Tenant
regarding the subject matter of this Lease and supersedes all prior related oral
statements and writings. Except for those set forth in this Lease, no
representations, warranties, or agreements have been made by Landlord or Tenant
to the other with respect to this Lease or the obligations of Landlord or Tenant
in connection with this Lease. This Lease shall be governed by, construed under
and be enforceable in accordance with the laws of the State of Illinois.

         21.13.   Calendar Days.

         Landlord and Tenant mutually, knowingly, irrevocably, voluntarily and
intentionally waive the right to a trial by jury in any action, proceeding or
counterclaim brought by either of the parties against the other in connection
with this Lease. Each party further warrants and represents that it has reviewed
this waiver with its legal counsel and that each has waived its jury trial
rights following consultation with legal counsel. This waiver applies to any and
all subsequent amendments and any other agreements relating to this Lease. In
the event of litigation, this Lease may be filed as a written consent to a trial
by the court sitting without a jury. Tenant further agrees that in the event
Landlord commences any summary proceeding for non-payment of Rent, Tenant will
not interpose any non-compulsory counterclaim of any nature or description in
such proceeding.

         21.16.   Landlord's Remedies Cumulative.

         No reference to any specific right or remedy will preclude Landlord
from exercising any other right, having any other remedy or maintaining any
action to which it may otherwise be entitled at law or in equity.

         21.17.   Prohibition Against Recordation.

         Tenant may not record all or any part of this Lease or any memorandum
of this Lease. Any recording by Tenant of all or any part of this Lease or any
memorandum of this Lease will be in violation of this Lease and will be void,
and Tenant agrees to indemnify Landlord, its trustees, beneficiaries, agents,
successors and assigns for any losses, damages or expenses of any nature
whatsoever incurred by reason of such recording. In the event Tenant records or
causes all or any part of this Lease or any memorandum of this Lease to be
recorded, Tenant hereby irrevocably appoints Landlord as Tenant's
attorney-in-fact, coupled with an interest, to execute and record a certificate
to clear any cloud on the title to the Building created by the improper
recordation. Tenant's authorization of Landlord to act as Tenant's
attorney-in-fact under this Section 21.17 will be exclusively for the purpose of
executing the certificate described above.

         21.18.   Confidentiality.

         Tenant agrees to maintain in strict confidence the information and
terms contained in this Lease, including but not limited to the Rent due from
Tenant hereunder (collectively the "Confidential Information"). Tenant shall not
under any circumstances disclose all or any portion of the Confidential
Information to any other person or entity, and shall maintain the Confidential
Information in the strictest confidence. Notwithstanding the foregoing, however,
Tenant may disclose the Confidential Information (i) to Tenant's employees,
attorneys, accountants, lenders and other consultants (the "Tenant Parties") to
the extent that the Tenant Parties reasonably need to know such Confidential
Information in order to perform services on behalf of Tenant; (ii) to the extent
required by any applicable statute, law, regulation, governmental authority or
court order; and (iii) in connection with any litigation or proceeding that may
arise between the parties in connection with this Lease. Tenant shall advise the
Tenant Parties of the provisions of this Section 21.18 and cause such Tenant
Parties to keep the Confidential Information confidential and otherwise comply
with the terms of this Section 21.18. Any breach by Tenant or any of the Tenant
Parties of any of the covenants and obligations contained in this Section 21.18
shall constitute a default under this Lease, in which event Landlord shall be
entitled to exercise any and all of its remedies under this Lease. The
undertakings of Tenant pursuant to this Section 21.18 shall survive the
termination of this Lease.

         21.19.   Joint and Several Liability.

         If two (2) or more individuals, corporations, partnerships or other
business associations (or any combination of two (2) or more thereof) sign this
Lease as Tenant, the liability of each such individual, corporation, partnership
or other business association to pay Rent and perform all of Tenant's other
obligations under this Lease are deemed to be joint and several.

         21.20.   Corporate Tenants.

         If Tenant is a corporation, the persons executing this Lease on behalf
of Tenant hereby covenant and warrant that Tenant is a duly constituted
corporation qualified to do business in the State of Illinois; all of Tenant's
franchise and corporate taxes have been paid to date; and such persons are duly
authorized by the board of directors of such corporation to execute and deliver
this Lease on behalf of Tenant.

         21.21. Option To Renew.

Provided an Event of Default is not in existence as of the date of the Renewal
Notice or on the commencement of the Renewal Period, Tenant shall have the
option (the "Renewal Option") to renew the Term of this Lease for one (1)
additional five (5) year period (the "Renewal Period"). If Tenant desires to
exercise the Renewal Option, Tenant must deliver written notice (the "Renewal
Notice") to Landlord not less than twelve (12) months prior to the scheduled
expiration of the Term; otherwise, the Renewal Option will lapse and be deemed
forever waived by Tenant. The same terms and conditions that are contained in
this Lease will apply during the Renewal Period, except that the Base Rent will
be ninety-five percent (95%) the then Prevailing Market Rental Rate (as defined
on Exhibit J), Landlord will make its determination of the then Prevailing
Market Rental Rate and send such determination to Tenant not less than ninety
(90) days prior to the commencement of the Renewal Period. Any attempt by Tenant
to exercise the Renewal Option by any method, at any time or under any
circumstances other than as specifically set forth herein will be null and void
and of no force or effect at the sole option and discretion of Landlord. In the
event that Tenant does not agree with Landlord's determination of the then
Prevailing Market Rental Rate, then Tenant must notify Landlord within ten (10)
business days after receipt of Landlord's determination that (a) it rescinds it
exercise of the Renewal Option (and the Renewal Option will be deemed waived by
Tenant), or (b) that it disputes such determination. In the event Tenant does
not notify Landlord of its dispute within such ten (10) business day period,
Tenant will be deemed to have accepted Landlord's determination of Prevailing
Market Rental Rate. If Tenant does notify Landlord of its dispute within such
ten (10) business day period, and if the parties are unable to resolve such
matter within thirty (30) days of the expiration of such ten (10) business day
period, then either party may request that the matter be resolved by binding
arbitration administered and conducted under the Commercial Arbitration Rules of
the American Arbitration Association and pursuant to the provisions of the
Illinois Uniform Arbitration Act. The parties agree that the arbitrator must be
a real estate professional with at least ten (10) years leasing experience in
the leasing of commercial office space in Chicago, Illinois. Not less than ten
(10) days prior to the arbitration hearing, the parties shall exchange with each
other their last, best determinations of the then Prevailing Market Rental Rate.
The arbitrator shall be limited to awarding only one or the other of the two
amounts submitted.

         21.22. Right of First Offer.

         So long as (i) Tenant does not then have under sublease in excess of
10,000 rentable square feet of the Premises and (ii) no Event of Default is in
existence as of the date Tenant notifies Landlord of Tenant's desire to exercise
its "Right of First Offer" (as defined below), Tenant shall have a right of
first offer (the "Right of First Offer") to rent any portion of the eleventh
(11th) floor of the Building (the "ROFO Premises") if the ROFO Premises become
available during the Term (including the Renewal Period), subject to the terms
and conditions set forth below. Notwithstanding anything contained herein to the
contrary, all or any portion of the ROFO Premises will not be considered
available and subject to Tenant's Right of First Offer if (x) any tenant of the
Building occupying the ROFO Premises (a "Pre-existing Tenant") pursuant to a
lease in effect as of the date of "Landlord's Notice" (as defined below) has a
right to extend or renew the term of its lease, (y) Landlord and the
Pre-existing Tenant agree to extend the term of such existing lease or enter
into a new lease for all or any portion of the ROFO Premises, or (z) any other
tenant in the Building having the right to lease or occupy all or any portion of
the ROFO Premises exercises its right to lease such portion of the ROFO Premises
(including any extension or renewal of such lease) if the ROFO Premises become

                                       28
<PAGE>

available during the Term, including after Tenant's failure to exercise its
Right of First Offer. Landlord represents that, as of the date of this Lease, no
other party has rights to lease any or all of the ROFO Premises except as
follows: A Tenant in the Building as of the date of this Lease has an expansion
option for between 8,000 and 10,000 rentable square feet on certain space
designated by Landlord on the 11th floor of the Building or above. Such
expansion right, if not exercised, expires after July 1, 2006. At any time
during the Term that Landlord desires to market or lease all or any portion of
the ROFO Premises, Landlord will notify Tenant in writing ("Landlord's Notice")
of Landlord's intention to so market or lease the ROFO Premises, together with
the date when the ROFO Premises can be made available to Tenant (the
"Availability Date") and the terms and conditions upon which Landlord is
prepared to lease all or any portion of such ROFO Premises (the "ROFO Premises
Terms and Conditions"). Tenant must then notify Landlord in writing within
twenty (20) days following Tenant's receipt of Landlord's Notice whether Tenant
desires to exercise its Right of First Offer. Tenant's Right of First Offer may
only be exercised as to the entire ROFO Premises identified in Landlord's
Notice. If Tenant declines to exercise its Right of First Offer or does not
notify Landlord of Tenant's election to exercise its Right of First Offer with
respect to the ROFO Premises within such twenty (20) day period, then Landlord
may enter into a new lease with any third party with respect to such ROFO
Premises and Tenant will be deemed to have waived its Right of First Offer with
respect to the ROFO Premises, identified in Landlord's Notice, except in the
event of a Subsequent Occurrence (as defined below). "Subsequent Occurrence"
means (i) that Landlord has not entered into a third party lease for a
substantial portion of the ROFO Space within nine (9) months of delivery of
Landlord's Notice or (ii) that Landlord has entered into a third party lease for
a substantial portion of the ROFO Space within such nine (9) month period and
such lease terminates prior to the Termination Date of this Lease. If Tenant
elects to exercise its Right of First Offer and so notifies Landlord within such
twenty (20) day period, then Tenant will accept a lease of the ROFO Premises as
of the Availability Date in its then "AS-IS" condition, subject to the ROFO
Premises Terms and Conditions, and otherwise on the same terms and conditions
contained in the Lease, except that (1) the Base Rent for the ROFO Premises will
be calculated at the rate per rentable square foot set forth on Exhibit I
attached; (2) the initial Base Rental rate for the ROFO Premises will be the
rate shown on Exhibit I for the Lease Year in which the ROFO Rent Commencement
Date falls and will correspondingly increase on the first day of each subsequent
Lease Year as shown on Exhibit I; (3) Tenant will be given a $30/RSF tenant
improvement allowance to be disbursed and administered in accordance with the
provisions of the Workletter; (4) the term "Premises" for all purposes of this
Lease will include the ROFO Premises, and (5) the numerator of Tenant's
Proportionate Share will increase by the amount of rentable square feet
contained within the ROFO Premises. Tenant will commence paying Rent (the "ROFO
Rent Commencement Date") for the ROFO Premises on the first to occur of (x) the
90th day following the Availability Date or (y) the date on which Tenant
commences its use of the ROFO Premises in the conduct of its business. Within
thirty (30) days after Tenant elects to exercise its Right of First Offer,
Landlord and Tenant will enter into an amendment to this Lease in order to
incorporate the ROFO Premises Terms and Conditions and to otherwise conform such
terms and provisions to this Lease.

         21.23.   Storage

         Landlord agrees to make available to Tenant up to Two Thousand (2,000)
square feet of storage space in the Building, provided Tenant notifies Landlord
in writing of its intention to lease such storage space on or before September
1, 2005. The storage space will be leased pursuant to the terms and provisions
of Landlord's customary storage lease agreement at a gross rental of twelve
dollars ($12.00) per rentable square foot and for a term co-terminus with the
Termination Date under this Lease.

         21.24.   Other Lease

         Tenant is presently a tenant at 360 N. Michigan Avenue, Chicago,
Illinois pursuant to a lease (with an affiliate of Landlord) dated January 3,
2003 and amended on March 31, 2000, November 30, 2000, July 3, 2002, September
30, 2002 and July 27, 2005 (such lease and all amendments collectively referred
to as the "Other Lease"). The amendment dated July 27, 2005 is referred to as
the "Fifth Amendment". Tenant acknowledges that any Event of Default as defined
under the Other Lease will constitute an Event of Default under this Lease. The
execution and delivery of this Lease is subject to and conditioned upon the
simultaneous execution and delivery of the Fifth Amendment. Pursuant to the
Fifth Amendment, among other things, the termination date of the Other Lease is
being advanced to such earlier date or dates as more particularly described
therein, such that from and after such advanced termination date or dates (and
subject to the provisions of the Fifth Amendment), the Other Lease shall
terminate as provided in the Fifth Amendment.

         21.25.   Rent Abatement/Cash Payment - Sublease

         Tenant will be entitled to either, at Landlord's election, a cash
payment or Base Rent abatement under this Lease equal to the 360 Sublease
Amounts (defined below). Pursuant to the Fifth Amendment, the landlord of the
Other Lease (the "360 Landlord") will be assigned all of Tenant's right, title
and interest under the 360 Subleases (defined below). The "360 Sublease Amounts"
means the aggregate base rent actually collected by the 360 Landlord from the
360 Subleases (defined below) under the 360 Subleases (defined below) from
August 1, 2005 until the earlier of (i) the Rent Commencement Date under this
Lease or (ii) the applicable termination dates of each of the respective 360
Subleases. The 360 Sublease Amounts will not include rent abated to the 360
Subtenants or any rent collected by the 360 Landlord from the 360 Subtenants for
space in the 360 North Michigan building not covered by the 360 Subleases. The
"360 Subtenants" under the "360 Subleases" are Amstadter, Relevant C, Roberts
and Kobald, Alacritude, Sotos and Robotics and are more fully described in the
Fifth Amendment. Within 45 days following the termination of the last of the 360
Subleases, Landlord will send Tenant a calculation of the 360 Sublease Amounts.
If Landlord elects Base Rent abatement, the 360 Sublease Amounts will be applied
to the next Base Rent payments due under this Lease until fully applied. If
Landlord elects a cash payment, Landlord will promptly deliver to Tenant a check
in the amount of the 360 Sublease Amounts.

                                   WORKLETTER

         THIS WORKLETTER (the "Workletter") is referred to in and specifically
made a part of that certain lease dated July 27, 2005 (the "Lease") by and
between ONE NORTH DEARBORN PROPERTIES, LLC, a Delaware limited liability company
("Landlord"), and COOLSAVINGS, INC., a Delaware corporation ("Tenant").

         1._______Lease. Landlord and Tenant agree that their respective rights
and obligations with respect to the construction of the Premises shall be as
provided in the Lease and in this Workletter. All of the terms used herein which
are defined in the Lease shall have the same meanings as provided in the Lease
unless otherwise stated herein.

         2. Work. Tenant, at its sole cost and expense, shall perform or cause
to be performed the work (the "Work") in the Premises provided for in the Plans
(as defined in paragraph 3 below) submitted to and approved by Landlord.
Tenant's Work shall be constructed in a good and workmanlike fashion, in
accordance with the requirements set forth below and in compliance with all
applicable laws, ordinances, rules and other governmental requirements. Tenant
shall commence the construction of the Work promptly following completion of the
preconstruction activities provided for in paragraph 3 below and shall
diligently proceed with all such construction. Tenant shall coordinate its Work
so as to avoid material interference with any other work being performed by or
on behalf of Landlord and other tenants at the Building. Any approvals or
consents by Landlord hereunder shall not unreasonably be withheld or delayed.

         3. Preconstruction Activities.

                  (a) On or before October 15, 2005, Tenant shall submit the
         following information and items to Landlord for Landlord's review and
         approval:

                           (i) a detailed construction schedule containing the
                  major components of the Work and the time required for each,
                  including the scheduled commencement date of construction of
                  the Work, milestone dates and the estimated date of completion
                  of construction;

                           (ii) an itemized statement of the estimated
                  construction cost, including permits and architectural and
                  engineering fees;

                           (iii) evidence reasonably satisfactory to Landlord of
                  Tenant's ability to pay the cost of the Work as and when
                  payments become due. Such evidence shall be in the form of an
                  unconditional written commitment from a responsible lender to
                  pay for the Work or evidence of current net assets in the form
                  of cash, cash equivalents or other liquid assets of Tenant
                  which have been and will continue to be segregated for payment
                  of the Work when due;

                           (iv) the names and addresses of Tenant's contractors
                  (and the contractors' subcontractors) to be engaged by Tenant
                  for the Work ("Tenant's Contractors"). Landlord has the right
                  to approve or disapprove Tenant's Major Contractors (as
                  defined below), which approval will not be unreasonably
                  withheld or delayed. Tenant shall not employ as Tenant's
                  Contractors any persons or entities disapproved by Landlord.
                  If Landlord has affirmatively approved only certain
                  contractor(s) and/or subcontractor(s) from Tenant's Major
                  Contractor list, Tenant shall employ as Tenant's Major
                  Contractors only those persons or entities so approved.
                  Landlord may, at its election, designate a list of approved
                  Major Contractors (at least three (3) designees for each
                  category): "Major Contractors" means Tenant's General
                  Contractor and the contractors performing work relating to the
                  electrical, mechanical, plumbing and life-safety systems;
<PAGE>

                           (v) certified copies of insurance policies or
                  certificates of insurance as hereinafter described. Tenant
                  shall not permit Tenant's Contractors to commence work until
                  the required insurance has been obtained and certified copies
                  of policies or certificates have been delivered to Landlord;
                  and

                           (vi) the Plans for the Work, which Plans shall be
                  subject to Landlord's approval in accordance with paragraph
                  3(b) below.

         Notwithstanding anything in this Section 3 to the contrary, Tenant may
(i) have reasonable access to the Premises for the purpose of space planning and
design activities and (ii) perform demolition work on the Premises after it has
obtained its demolition permit and furnished Landlord with its demolition plans
and applicable insurance certificates, which plans and insurance certificates
have been reasonably approved by Landlord.

         Tenant will update such information and items by notice to Landlord of
any material changes.

                  (b) As used in this Workletter, the term "Plans" shall mean
         full and detailed architectural and engineering plans and
         specifications covering the Work (including, without limitation,
         architectural, mechanical and electrical working drawings for the
         Work). The Plans shall be subject to Landlord's approval and the
         approval of all local governmental authorities requiring approval, if
         any. Landlord shall give its approval or disapproval (giving general
         reasons in case of disapproval) of the Plans within seven (7) days
         after receipt thereof by Landlord. Landlord agrees not to unreasonably
         withhold its approval of said Plans; provided, however, that Landlord
         shall not be deemed to have acted unreasonably if it withholds its
         consent because, in Landlord's opinion: (i) the Work is likely to
         affect adversely Building systems, the structure of the Building or the
         safety of the Building and its occupants; (ii) the Work would
         materially increase Landlord's ability to furnish services to Tenant or
         other tenants; (iii) the Work would increase the cost of operating the
         Building; (iv) the Work would violate any governmental laws, rules or
         ordinances; (v) the Work contains or uses hazardous or toxic materials;
         (vi) the Work would adversely affect the appearance of the Building;
         (vii) the Work would adversely affect another tenant's premises; or
         (viii) the Work is prohibited by any mortgage on the Building. The
         foregoing reasons, however, shall not be exclusive of the reasons for
         which Landlord may withhold consent, whether or not such other reasons
         are similar to or dissimilar from the foregoing. Landlord shall
         cooperate with Tenant by discussing or reviewing preliminary plans and
         specifications, at Tenant's request prior to completion of the full,
         final detailed Plans, in order to expedite preparation of the final
         Plans and the approval process. If Landlord notifies Tenant that
         changes are required to the final Plans submitted by Tenant, Tenant
         shall, within ten (10) days thereafter, submit to Landlord for its
         approval the Plans as amended in accordance with the changes so
         required. The Plans shall also be revised, and the Work shall be
         changed, to incorporate any work required in the Premises by any local
         governmental field inspector.


                                       2
<PAGE>

                  (c) Landlord shall give its approval or disapproval (giving
         general reasons in case of disapproval) of all items other than the
         Plans set forth in Section 3(b) above within ten (10) days after
         receipt by Landlord.

                  (d) No Work shall be undertaken or commenced by Tenant in the
         Premises until:

                           (i) the Plans have been submitted to and approved by
Landlord;

                           (ii) all necessary building permits have been applied
                  for or obtained by Tenant;

                           (iii) all required insurance coverages have been
                  obtained by Tenant. (Failure of Landlord to receive evidence
                  of such coverage upon commencement of the Work shall not waive
                  Tenant's obligations to obtain such coverages.);

                           (iv) proper provision, which is reasonably
                  satisfactory to Landlord, has been made by Tenant for payment
                  in full of the cost of the Work in excess of Landlord's
                  Contribution, if any;

                           (v) items required to be submitted to Landlord prior
                  to commencement of construction of the Work have been so
                  submitted and have been approved, where required;

                           (vi) the construction escrow referred to in paragraph
                  10, if any, hereof has been established; and

                           (vii) Landlord has given written notice that the Work
                  can proceed, subject to such reasonable conditions as Landlord
                  may impose, except that if all conditions set forth in clauses
                  (i) through (vi) above have been satisfied, Landlord shall be
                  deemed to have given its notice to proceed.

         4. Delays. No delays in completion of the Work will in any way excuse
or delay Tenant's obligation to pay Base Rent from and after the Rent
Commencement Date, except for a delay caused by Landlord.

         5. Change Orders. All changes to the final Plans requested by Tenant
(other than minor field changes which do not materially affect the Plans) must
be approved by Landlord in advance of the implementation of such changes as part
of the Work. All delays caused by Tenant-initiated change orders, including,
without limitation, any stoppage of work during the change order review process,
are solely the responsibility of Tenant and shall cause no delay in the
commencement of the Lease or the rental and other obligations therein set forth.

         6. Standards of Design and Construction and Conditions of Tenant's
Work.


                                       3
<PAGE>

         All work done in or upon the Premises by Tenant shall be done according
to the standards set forth in this paragraph 6, except as the same may be
modified in the Plans approved by or on behalf of Landlord and Tenant.

                  (a) Tenant's Plans and all design and construction of the Work
         shall comply with all applicable statutes, ordinances, regulations,
         laws, codes and industry standards, including but not limited to
         requirements of Landlord's fire insurance underwriters. Approval by
         Landlord of the Plans shall not constitute a waiver of this requirement
         or assumption by Landlord of responsibility for compliance. Where
         several sets of the foregoing laws, codes and standards must be met,
         the strictest shall apply where not prohibited by another law, code or
         standard.

                  (b) Tenant shall obtain, at its own cost and expense, all
         required building permits and, when construction has been completed,
         shall use commercially reasonable efforts to obtain, at its own cost
         and expense, an occupancy permit for the Premises (if issued by the
         City of Chicago) which permit shall be delivered to Landlord. Tenant's
         failure to obtain such permits shall not cause a delay in the
         commencement of the Lease or the rental and other obligations therein
         set forth.

                  (c) Tenant's Contractors shall be licensed contractors,
         possessing good labor relations, capable of performing quality
         workmanship and working in harmony with Landlord's contractors and
         subcontractors and with other contractors and subcontractors in the
         Building.

                  (d) Landlord shall have the right, but not the obligation, to
         perform on behalf of and for the account of Tenant, subject to
         reimbursement by Tenant, any work (i) which Landlord reasonably deems
         to be necessary on an emergency basis, (ii) which pertains to the
         erection of temporary safety barricades or signs during construction,
         or (iii) which pertains to other work in the Building.

                  (e) Tenant shall use only new, quality materials in the Work,
         except where explicitly shown otherwise in the Plans approved by
         Landlord and Tenant. Tenant shall obtain warranties of at least one (1)
         year's duration from the completion of the Work against defects in
         workmanship and materials on all work performed and equipment installed
         in the Premises as part of the Work.

                  (f) Tenant and Tenant's Contractors shall make all efforts and
         take all steps appropriate to construction activities undertaken in a
         fully occupied, first-class renovated office building so as not to
         interfere with the operation of the Building and shall, in any event,
         comply with all reasonable rules and regulations existing from time to
         time at the Building. Tenant and Tenant's Contractors shall take all
         precautionary steps to minimize dust, noise and construction traffic
         and to protect their facilities and the facilities of others affected
         by the Work and to properly police same. Construction equipment and
         materials are to be kept within the Premises, and delivery and loading
         of equipment and materials shall be done at such locations and at such
         time as Landlord shall direct so as not to burden the construction or
         operation of the Building.

                  (g) Landlord shall have the right to order Tenant or any of
         Tenant's Contractors who violate the requirements imposed on Tenant or
         Tenant's Contractors in performing work to cease work and remove its
         equipment and employees from the Building, provided 24 hours notice is
         given and the violation is not cured within such period. No such action
         by Landlord shall delay the commencement of the Lease or the rental and
         other obligations therein set forth.

                                       4
<PAGE>

                  (h) Landlord will be responsible for all utility costs or
         charges for any service (including HVAC, hoisting or freight elevator
         and the like) through the earlier of the Rent Commencement Date under
         this lease or April 1, 2006. Tenant shall pay for all support services
         provided by Landlord's contractors. All use of freight elevators is
         subject to scheduling by Landlord. Tenant shall arrange and pay for
         removal of construction debris and shall not place debris in the
         Building's waste containers, for which Landlord will provide space for
         placement of such waste containers.

                  (i) Tenant shall permit access to the Premises, and the Work
         shall be subject to inspection, by Landlord and Landlord's architects,
         engineers, contractors and other representatives at all times during
         the period in which the Work is being constructed and installed and
         following completion of the Work.

                  (j) Tenant shall proceed with its work expeditiously,
         continuously and efficiently for the construction of the Work. Tenant
         shall notify Landlord upon completion of the Work and shall furnish
         Landlord and Landlord's title insurance company with such further
         documentation as may be necessary under paragraphs 9 below.

                  (k) Tenant shall have no authority to deviate from the Plans
         in performance of the Work, except pursuant to a written change order
         pursuant to Paragraph 5 hereof. Tenant shall furnish to Landlord
         "as-built" drawings of the Work within thirty (30) days after
         completion of the Work.

                  (l) Landlord shall have the right to run utility lines, pipes,
         conduits, duct work and component parts of all mechanical and
         electrical systems where necessary or desirable through the Premises in
         a manner that does not unreasonably interfere with Tenant's use of the
         Premises or unreasonably interfere with Tenant's completion of the
         Work, to repair, alter, replace or remove the same, and to require
         Tenant to install and maintain proper access panels thereto.

                  (m) Tenant shall impose on and enforce all applicable terms of
         this Workletter against Tenant's architect and Tenant's Contractors.

         7.       Insurance and Indemnification.

                  (a) In addition to any insurance which may be required under
         the Lease, Tenant shall secure, pay for and maintain or cause Tenant's
         Contractors to secure, pay for and maintain during the continuance of
         construction and fixturing work within the Building or Premises,
         insurance in the following minimum coverages and limits of liability:

                           (i) workers' compensation and employers' liability
                  insurance with limits of not less than $500,000.00, or such
                  higher amounts as may be required from time to time by any
                  employee benefit acts or other statutes applicable where the
                  work is to be performed, and in any event sufficient to
                  protect Tenant's Contractors from liability under the
                  aforementioned acts;

                                       5
<PAGE>

                           (ii) comprehensive or commercial general liability
                  insurance (including contractors' protective liability) in an
                  amount not less than $2,000,000.00 per occurrence, whether
                  involving bodily injury liability (or death resulting
                  therefrom) or property damage liability or a combination
                  thereof with a minimum aggregate limit of $2,000,000.00, and
                  with umbrella coverage with limits not less than
                  $10,000,000.00. Such insurance shall provide for explosion and

                  contractual liability coverage and shall insure Tenant's
                  Contractors against any and all claims for bodily injury,
                  including death resulting therefrom, and damage to the
                  property of others and arising from its operations under the
                  contracts whether such operations are performed by Tenant's
                  Contractors or by anyone directly or indirectly employed by
                  any of them;

                           (iii) comprehensive automobile liability insurance,
                  including the ownership, maintenance and operation of any
                  automotive equipment, owned, hired or non-owned, in an amount
                  not less than $500,000.00 for each person in one accident and
                  $1,000,000.00 for injuries sustained by two or more persons in
                  any one accident, and property damage liability in an amount
                  not less than $1,000,000.00 for each accident. Such insurance
                  shall insure Tenant's Contractors against any and all claims
                  for bodily injury, including death resulting therefrom, and
                  damage to the property of others arising from its operations
                  under the contracts, whether such operations are performed by
                  Tenant's Contractors or by anyone directly or indirectly
                  employed by any of them;

                           (iv) "all risk" builder's risk insurance upon the
                  entire Work to the full insurable value thereof. This
                  insurance shall include the interests of Landlord and Tenant
                  (and their respective contractors and subcontractors of any
                  tier to the extent of any insurable interest therein) in the
                  Work and shall insure against the perils of fire and extended
                  coverage and shall include "all risk" builder's risk insurance
                  for physical loss or damage including, without duplication of
                  coverage, theft, vandalism and malicious mischief. If portions
                  of the Work are stored off the site of the Building or in
                  transit to said site are not covered under said "all risk"
                  builder's risk insurance, then Tenant shall effect and
                  maintain similar property insurance on such portions of the
                  Work. Any loss insured under said "all risk" builder's risk
                  insurance is to be adjusted with Landlord and Tenant and made
                  payable to Landlord as trustee for the insureds, as their
                  interests may appear.

         All policies (except the workers' compensation policy) shall be
endorsed to include as additional insured parties Landlord and its
beneficiaries, their partners, directors, officers, employees and agents,
Landlord's contractors, Landlord's architects, and such additional persons as
Landlord may designate. The waiver of subrogation provisions contained in the
Lease shall apply to all insurance policies (except the workers' compensation
policy) to be obtained by Tenant pursuant to this paragraph. The insurance
policy endorsements shall also provide that all additional insured parties shall

or nonrenewal of coverage and shall provide that the insurance coverage afforded

                  (b) Without limitation of the indemnification provisions
         contained in the Lease, to the fullest extent permitted by law Tenant
         agrees to indemnify, protect, defend and hold harmless Landlord,
         Landlord's contractors and Landlord's architects and their partners,
         directors, officers, employees and agents, from and against all claims,
         liabilities, losses, damages and expenses of whatever nature arising
         out of or in connection with the Work or the entry of Tenant or
         Tenant's Contractors into the Building and the Premises, including,
         without limitation, mechanics' liens or the cost of any repairs to the
         Premises or Building necessitated by activities of Tenant or Tenant's
         Contractors and bodily injury to persons or damage to the property of
         Tenant, its employees, agents, invitees or licensees or others. It is
         understood and agreed that the foregoing indemnity shall be in addition
         to the insurance requirements set forth above and shall not be in
         discharge of or in substitution for same or any other indemnity or
         insurance provision of the Lease.

         8.       Landlord's Contribution; Excess Amounts.

         In accordance with Section 9 below, Landlord shall make a dollar
contribution in the amount of One Million Three Hundred Fifty Thousand Dollars
($1,350,000) (based on $30.00 per Agreed Rentable Sq. Ft.) ("Landlord's
Contribution") to reimburse Tenant or pay on Tenant's behalf, as applicable, for
the cost of the Work, including its architectural, engineering, and third party
consulting fees; telephone/data costs; and furniture, fixtures and equipment.
Notwithstanding anything this Workletter to the contrary, Landlord may deduct
from Landlord's Contribution any amounts due to Landlord or its architects or
engineers under this Workletter. Any portion of Landlord's Contribution which is
not used by Tenant shall be applied to the Base Rent next due until fully
expended.

         9. Construction Escrow. Prior to commencement of any construction or
payment to Tenant or to any of Tenant's Contractors, Tenant shall, at Landlord's
option, establish a construction escrow or other payment procedure acceptable to
Landlord and each holder of a mortgage on the Building providing for payment to
Tenant's Contractors and payment of all other costs associated with the Work as
the Work progresses, upon the satisfactory review of lien waivers and sworn
statements from Tenant's Contractors and other applicable parties and, if
applicable, upon the title insurance company's willingness to issue title
insurance over mechanics' liens relating to Tenant's contracts and the Work to
the date of each draw. As set forth below, Landlord shall make periodic funding
of Landlord's Contribution to pay for the Work when required under contracts for
the Work. Tenant shall not permit the Premises or the Building to become subject
to any lien on account of labor, material or services furnished to Tenant. If
Landlord's Contribution is less than the estimated cost of the Work, Tenant
shall, from time to time, deposit funds into such escrow as Landlord may
reasonably direct, in amounts sufficient to pay the excess costs of the Work.
From and after the determination that Tenant must make deposits to cover the
excess costs of the Work, the amount Tenant shall deposit for each monthly
disbursement will be that portion of the excess spread equally over the
remaining number of monthly payments to Tenant's contractors and subcontractors,
as reasonably determined by Landlord. Notwithstanding the foregoing computation,
any portion of the unpaid excess shall be paid by Tenant by the first to occur
of (i) Landlord's final payment of the Landlord's Contribution or (ii) the Rent
Commencement Date. Tenant may not withdraw funds except to pay Tenant's
Contractors, unless Landlord has consented to such withdrawal. The construction
escrow agreement, if applicable, shall contain the foregoing restriction on
withdrawal of funds by Tenant and shall also provide that if Tenant fails to pay
for the Work when due or if any mechanics' lien is filed in connection with the
Work, (and such payment is not made within ten (10) business days after notice
from Landlord or such mechanic's lien is not released or otherwise dealt with as
provided in the Lease) Landlord may use and withdraw the funds in the escrow to
pay for the Work or remove the lien without Tenant's consent. Tenant shall
provide such contractor's affidavits, tenant (owner) statements, partial and
final waivers of lien, architect's certificates and any additional documentation
(including, without limitation, Tenant or contractor personal undertakings)
which may be requested by such title insurance company or any holder of a
mortgage on the Building in connection with said escrow or consistent with any
other title insurance requirements concerning the Work. Landlord agrees to
process draw requests within thirty (30) days of receipt of all required
documentation.

         10.      Freight Elevators.

         While Tenant completes Tenant's Work, Tenant, at no additional cost,
shall have access to the Building's freight elevators, for hoisting and access
to the Premises.

         11.      Miscellaneous.

                  (a) Except as expressly set forth herein, Landlord has no
         other agreement with Tenant to improve the Premises and has no other
         obligation to do any other work or pay any amounts with respect to the
         Premises. Any other work in the Premises which may be permitted by
         Landlord pursuant to the terms and conditions of the Lease or this
         Workletter shall be done at Tenant's sole cost and expense and in
         accordance with the terms and conditions of the Lease.

                  (b) This Workletter shall not be deemed applicable to any
         additional space added to the original Premises at any time or from
         time to time, whether by any options under the Lease or otherwise, or
         to any portion of the original Premises or any additions thereto if the
         initial term of the Lease is renewed or extended, whether by any
         options under the Lease or otherwise, unless expressly so provided in
         the Lease or any amendment or supplement thereto.

                  (c) The failure by Tenant to pay any amount(s) due Landlord
         pursuant to this Workletter within the time periods herein stated shall
         be deemed a default under the terms of the Lease, for which Landlord
         shall be entitled to exercise all remedies available to Landlord for
         nonpayment of Rent, and all late payments shall be subject to interest
         and late charges as provided in the Lease.

                  (d) This Workletter is being executed in conjunction with the
         Lease and is subject to the limitation of Landlord's liability set
         forth therein. In the event of a conflict between the Lease and this
         Workletter, the terms of this Workletter shall govern.

                          PREVAILING MARKET RENTAL RATE

         "Prevailing Market Rental Rate" shall mean the fixed base rent per
annum which, on such date, a willing landlord under no compulsion would agree to
accept from a tenant, having the creditworthiness of Tenant, and such a willing
tenant under no compulsion would agree to pay, for a lease of such space for
such period, on all of the terms and conditions of this Lease to be applicable
including (i) any construction allowance and/or free rent period to which Tenant
will be entitled, or the absence of such allowance and/or free rent period, as
the case may be, (ii) Tenant's obligation to pay additional rent based upon
operating expenses and taxes and/or the base year or amount to be applicable to
such obligation, (iii) all other economic concessions, and (iv) all applicable
market brokerage commissions paid in the downtown Chicago market.

         The Prevailing Market Rental Rate shall be ascertained on a "net
effective" or "level pay" basis by (a) calculating the net present value of (i)
the net rental rate; (ii) any rent adjustments other than for increases in
operating expenses and real estate taxes; (iii) Landlord concessions including
but not limited to demolition, tenant improvement contributions, lease
assumptions, credits for rent, operating expenses or real estate taxes; and (iv)
brokerage commissions; and then (b) amortizing the net present value amount over
the remaining term of the Lease (or renewal period) at a market interest rate
utilized by other landlords of similar properties in downtown Chicago.
