5445 NE Dawson Creek Parkway
Hillsboro, Oregon 97124                                                  RADISYS

        RadiSys considers the establishment and maintenance of a sound and vital
management to be essential to protecting and enhancing the best interests of
RadiSys and its shareholders. In order to induce Executive to remain employed by
RadiSys in the face of uncertainties about the long-term strategies of RadiSys
and their potential impact on the scope and nature of Executive's position with
RadiSys, this Agreement, which has been approved by the Board of Directors of
RadiSys, sets forth the bonus and severance benefits that RadiSys will provide
to Executive in the event of Termination of Executive's Employment by RadiSys
without Cause during the period beginning the date of this Agreement and ending
eighteen (18) months following the first day of employment of the RadiSys Chief
Executive Officer hired to succeed Ronald A. Dilbeck (such period is referred to
as the "Term"), under the circumstances described in this Agreement.

        1. EMPLOYMENT RELATIONSHIP. Executive is currently employed by RadiSys
as Sr. Vice President Corporate Marketing and Business Development. Executive
and RadiSys acknowledge that either party may terminate this employment
relationship at any time and for any or no reason, subject to the obligation of
RadiSys to provide the benefits specified in this Agreement in accordance with
the terms hereof.

        2. RELEASE OF CLAIMS; RESIGNATION. In consideration for and as a
condition precedent to receiving the severance benefits outlined in this
Agreement, Executive agrees to execute a Release of Claims in the form attached
as EXHIBIT A ("Release of Claims") and to provide a written resignation of
employment and all corporate offices in the form attached as EXHIBIT B
("Resignation"). Executive promises to execute and deliver the Release of Claims
and the Resignation to RadiSys within the later of (a) forty-five (45) days from
the date

<PAGE>

Executive receives the Release of Claims or (b) the last day of Executive's
active employment.

        3. COMPENSATION UPON TERMINATION; NONCOMPETITION. In the event of a
Termination of Executive's Employment (as defined in Section 6.1) at any time
during the Term other than for Cause (as defined in Section 6.2 of this
Agreement), Death or Disability (as defined in Sections 6.4 and 6.3 of this
Agreement), and contingent upon Executive's execution, delivery and
nonrevocation of the Release of Claims, execution and delivery of the
Resignation, and continued noncompetition with RadiSys, Executive shall be
entitled to the following benefits in lieu of any other compensation for periods
subsequent to the date of termination:

           3.1 As bonus pay, RadiSys shall pay Executive, in periodic payments
on regular paydays over twelve (12) months beginning on the later of (a) the
termination of employment or (b) eight (8) days after execution and
nonrevocation of the Release of Claims, the total amount equal to twelve (12)
months of the Executive's then current base salary subject to the following
restrictions:

               3.1.1 During the period of such periodic payments, Executive
agrees that Executive will not individually, and will not serve as or become a
director, officer, partner, limited partner, employee, agent, representative,
material stockholder (greater than ten percent (10%) of a company's outstanding
shares), creditor, or consultant of or to, or serve in any other capacity with
any business worldwide which shall in any manner, directly or indirectly:

                   (a) Engage or prepare to engage in any business which
competes with RadiSys;

                   (b) Solicit, hire or otherwise assist in any effort that
attempts to employ or otherwise utilize the services of any RadiSys employee;

                   (b) Solicit, divert, or accept orders for goods or services
that are substantially competitive with the goods or services sold by RadiSys
from any customer of RadiSys.

               3.1.2 Executive acknowledges and agrees that the time, scope,
worldwide geographic area, and other provisions of this Section 3.1 and its
subparts are reasonable under the circumstances. Executive further agrees that
if, at any time, despite the express agreement of the parties hereto, a court of
competent jurisdiction holds that any portion of this Section 3.1 and its
subparts are unenforceable for any reason, the maximum restrictions of time,
scope, or geographic area reasonable under the circumstances, as determined by
such court, will be substituted for any such restrictions held unenforceable.

           3.2 Executive may be entitled to extend coverage under any group
health plan in which Executive and Executive's dependents are enrolled at the
time of termination of employment under the COBRA continuation laws for the
eighteen- (18-) month statutory period, or so long as Executive remains eligible
under COBRA.

                                       2
<PAGE>

           RadiSys will pay Executive a lump sum payment in an amount equivalent
to the reasonably estimated cost Executive may incur to extend such coverage for
a period of twelve (12) months under the COBRA continuation laws Executive and
Executive's dependents group health and dental plan coverage in effect at the
time of termination. Subject to Section 4, Executive may use the net payment, as
well as any payment made under Section 3.1, for such COBRA continuation coverage
or for any other purpose.

           3.3 Executive shall be entitled to a portion of the benefits under
the Executive MBO Plan or the incentive plan in effect at the time of
termination, if any payment is earned under such plan, prorated for the portion
of the incentive plan year during which Executive was a participant. For
purposes of this Agreement, Executive's participation in any annual targeted
incentive plan will be considered to have ended on Executive's last day of
active employment. Prorated awards, if any, shall not be due and payable by
RadiSys to Executive until the date that all awards are paid to other eligible
employees after the incentive plan year has ended. Unless the applicable
incentive plan provides for a greater payment for a participant whose employment
terminates prior to the end of an incentive plan year (in which case the
applicable plan payment shall be made), the proration shall be calculated
pursuant to this Section 3.3. The payment, if any, that would have been made
under Executive's award had Executive been made a participant for the full
incentive plan year shall be calculated after the end of the incentive plan
year. Such amount shall be divided by the total number of days in the incentive
plan year and the result multiplied by the actual number of days during the
incentive plan year of Executive's participation in the plan.

           3.4 RadiSys will pay up to Fifteen Thousand and No/100 Dollars
($15,000.00) to Executive or to a third party outplacement firm selected by
Executive so that Executive may obtain career counseling assistance to Executive
for a period of one (1) year following Executive's termination date if Executive
so chooses.

        4. WITHHOLDING; SUBSEQUENT EMPLOYMENT. All payments provided for in
Sections 3.1, 3.2, 3.3 and 3.4 of this Agreement are subject to and will be
reduced by applicable withholding obligations imposed by federal, state or local
laws and regulations. Except as provided in Section 3.1 and its subparts, the
amount of any payment provided for in this Agreement shall not be reduced,
offset or subject to recovery by RadiSys because of any compensation earned by
Executive as the result of employment by another employer after termination.

                                       3
<PAGE>

        5. OTHER AGREEMENTS. In the event that severance benefits are payable to
Executive under any other agreement with RadiSys in effect at the time of
termination (including but not limited to any change of control, "golden
parachute" or employment agreement, but excluding for this purpose any stock
option agreement or stock bonus agreement or stock appreciation right agreement
that may provide for accelerated vesting or related benefits upon the occurrence
of a change in control), the benefits provided in this Agreement shall not be
payable to Executive. Executive may, however, elect to receive all of the
benefits provided for in this Agreement in lieu of all of the benefits provided
in all such other agreements. Any such election shall be made with respect to
the agreements as a whole, and Executive cannot select some benefits from one
agreement and other benefits from this Agreement.

        6. DEFINITIONS.

           6.1 Termination of Executive's Employment. Termination of Executive's
Employment means that RadiSys has terminated Executive's employment with RadiSys
(including any subsidiary of RadiSys). If Executive is assigned additional or
different titles, tasks or responsibilities from those currently held or
assigned, consistent with Executive's areas of professional expertise, whether
at RadiSys or any subsidiary of RadiSys, such circumstances shall not constitute
a Termination of Executive's Employment.

           6.2 Cause. Termination of Executive's Employment for "Cause" shall
mean Termination upon (a) the willful failure by Executive to perform
substantially Executive's reasonably assigned duties with RadiSys after written
notice outlining the deficiencies and after a demand for substantial performance
is delivered to Executive by the Board, Chief Executive Officer or President of
RadiSys or (b) the willful engaging by Executive in illegal conduct which is
materially and demonstrably injurious to RadiSys. No act, or failure to act, on
Executive's part shall be considered willful unless done or omitted to be done,
by Executive without reasonable belief that Executive's action or omission was
in, or not opposed to, the best interests of the Company. Any act, or failure to
act, based upon authority given pursuant to a resolution duly adopted by the
Board of Directors shall be conclusively presumed to be done, or omitted to be
done, by Executive in the best interests of the Company.

           6.3 Disability. Termination of Executive's Employment based on
"Disability" shall mean termination without further compensation under this
Agreement, due to Executive's absence from Executive's full-time duties with
RadiSys for one hundred eighty (180) consecutive days as a result of Executive's
incapacity due to physical or mental illness, unless within thirty (30) days
after notice of termination by RadiSys following such absence Executive shall
have returned to the full-time performance of Executive's duties.

           6.4 Death. Executive's employment terminates upon Executive's death
without further compensation under this Agreement.

        7. SUCCESSORS; BINDING AGREEMENT.

           7.1 This Agreement shall be binding on and inure to the benefit of
RadiSys and its successors and assigns.

           7.2 This Agreement shall inure to the benefit of and be enforceable
by Executive and Executive's legal representatives, executors, administrators
and heirs.

        8. RESIGNATION OF CORPORATE OFFICES. Executive will resign employment
and Executive's office, if any, as a director, officer or trustee of RadiSys,
its subsidiaries or affiliates, effective as of the date of termination of
employment. Executive agrees to provide RadiSys the Resignation that conforms
with Exhibit B and that no severance will be paid until after the Resignation is
provided.

        9. GOVERNING LAW, ARBITRATION. This Agreement shall be construed in
accordance with and governed by the laws of the State of Oregon. Executive and
RadiSys agree that any dispute or controversy arising under or in connection
with this Agreement or the breach thereof, shall be settled exclusively by
arbitration under the commercial rules of the American Arbitration Association,
and judgment upon the award rendered by the Arbitrator may be entered in any
Court having jurisdiction thereof. In the event of any arbitration or
administrative or civil action to enforce the provisions of this Agreement, each
party agrees to bear its own attorney fees and costs at any proceeding, trial
and/or on appeal.

        10. AMENDMENT. No provision of this Agreement may be modified unless
such modification is agreed to in a writing signed by Executive and RadiSys.

Lease Commencement Date in accordance with the provisions of SCHEDULE 6 in
order to perform the Work (as defined in the Work Letter Agreement attached

Rent and Tenant's Pro Rata Share of Excess Operating Costs, taxes and insurance
(other than the insurance required pursuant to SCHEDULE 6) for the period prior
to the Lease Commencement Date, but all other covenants and conditions of this
Lease shall be binding on the parties commencing at such prior occupancy.

                                 ARTICLE THREE
                                PAYMENT OF RENT

     3.1 RENT:

     a.  Tenant shall pay each monthly installment of Base Rent in advance on
     the first calendar day of each month. During the Base Year, no Excess
     Operating Costs (as defined in Section 3.3 below) shall be paid by Tenant.
     For each calendar year following the Base Year, Tenant shall pay each
     monthly installment of Tenant's Pro Rata Share of Excess Operating Costs in
     advance together with each monthly installment of Base Rent. Monthly
     installments for any fractional calendar month, at the beginning or end of
     the Lease Term, shall be prorated based on the number of days in such
     month. Base Rent, together with all other amounts payable by Tenant to
     Landlord under this Lease, including, without limitation, any late charges
     and interest due Landlord for Rent not paid when due, shall be sometimes
     referred to collectively as "RENT". Tenant shall pay all Rent, without
     deduction or set-off, to Landlord or Managing Agent at a place specified by
     Landlord. Rent not paid when due shall bear interest until paid, at the
     rate of two percent (2%) per month, or at the maximum rate allowed by law,
     whichever is less, from the date when due. Tenant shall also pay a
     processing charge of Fifty Dollars ($50.00) with each late payment of Rent.
     Landlord agrees to waive the processing and interest charge for late
     payments of Rent once during any calendar year during the Lease Term,
     provided any such late Rent payment is paid in full within ten (10) days of
     the date when due. Nothing contained in this paragraph shall be deemed to
     prohibit Tenant from being able to credit excess Allowance (as defined in
     SCHEDULE 6) to Base Rent due hereunder to the extent permitted under
     Paragraph 3.05 of SCHEDULE 6.

     b.  Notwithstanding anything to the contrary contained herein, Landlord
     agrees to abate Base Rent for (i) the first three (3) months and eighteen
     (18) days of the first year of the Lease Term, and (ii) the first month of
     the second year of the Lease Term.

     3.2 DEPOSIT:

     a.  Tenant has paid to Landlord the Deposit as security for performance of
     Tenant's obligations under this Lease. In the event Tenant fully complies
     with all the terms and conditions of this Lease, the Deposit shall be
     refunded to Tenant, without interest unless otherwise required by law, upon
     expiration of this Lease. Landlord may, but is not obligated to, apply a
     portion of the Deposit to cure any default hereunder and Tenant

                                       3

<PAGE>

     shall pay on demand the amount necessary to restore the Deposit in full
     within thirty (30) days after notice by Landlord.

     b.  Notwithstanding anything to the contrary contained in this Section 3.2,
     the Deposit shall be in the form of a letter of credit (the "LETTER OF
     CREDIT") and the following additional provisions shall apply. The Letter of
     Credit and any substitute Letter of Credit shall be issued in a form and by
     a bank approved by Landlord (the "BANK"), which approval shall not be
     unreasonably withheld or delayed. The Bank shall have net worth of not less
     than Five Hundred Million Dollars ($500,000,000). Tenant shall deposit the
     Letter of Credit with Landlord upon Tenant's execution of this Lease.
     Tenant shall maintain the Letter of Credit, or a substitute Letter of
     Credit, in accordance with the terms hereof, in full force and effect at
     all times during the Lease Term and for a period of thirty (30) days
     thereafter (the last day of such thirty (30) day period shall be referred
     to as the "RETURN DATE"). If the Letter of Credit expires before the Return
     Date, Tenant shall replace the Letter of Credit deposited with Landlord by
     providing Landlord with a substitute Letter of Credit at least thirty (30)
     days prior to the expiration date of the then effective Letter of Credit
     being held by Landlord in the amount required hereunder. Landlord shall
     have the right to draw upon the Letter of Credit and apply such Letter of
     Credit or portion thereof to cure any default of Tenant under this Lease in
     same manner described in Section 3.2(a). Within thirty (30) days of the
     Return Date, Landlord shall return the Letter of Credit, or so much thereof
     as shall not have theretofore been applied in accordance with the terms of
     this Section 3.2 or drawn upon by Landlord and applied to cure any default
     of Tenant existing as of such date. Notwithstanding anything to the
     contrary contained herein, so long as there shall not have been any (i)
     monetary Event of Default hereunder, or (ii) non-monetary Event of Default
     which shall not have been cured within applicable cure periods. Tenant
     shall have the right, commencing on the second (2nd) anniversary of the
     Lease Commencement Date and on each anniversary thereafter, to reduce the
     amount of the Letter of Credit by 20% per year (i.e., by $69,432.00 per
     year); provided, however, that in no event shall the Letter of Credit be
     reduced to less than 50% of the initial Security Deposit amount. Tenant may
     exercise the foregoing right to reduce the Letter of Credit by providing
     Landlord with a substitute Letter of Credit in the form and amount required
     hereunder.

     3.3 OPERATING COSTS: Tenant shall pay Tenant's Pro Rata Share of any Excess
Operating Costs as set forth below. As used herein, "EXCESS OPERATING COSTS"
shall mean any excess of (i) Landlord's Operating Costs for any calendar year
following the Base Year over (ii) the actual Operating Costs of the Base Year.

     a. "OPERATING COSTS" shall mean all reasonable and actual expenses relating
     to the Leased Premises, the Building or the Project, including but not
     limited to: real estate taxes and assessments; gross rents, sales, use,
     business, corporation, franchise or other taxes (except income taxes);
     utilities not separately chargeable to other tenants; insurance premiums
     and (to the extent used) deductibles; maintenance, repairs and
     replacements; refurbishing and repainting; cleaning, janitorial and other
     services; equipment, tools, materials and supplies; air conditioning,
     heating and elevator service; property management including management fees
     (provided that such management fees shall not exceed 3% of gross revenues
     for the Project); security; employees and contractors;

                                       4
<PAGE>

     resurfacing and restriping of walks, drives and parking areas; signs,
     directories and markers; landscaping; and snow and rubbish removal.
     Operating Costs shall not include (a) expenses for legal services, (b)
     real estate brokerage and leasing commissions, (c) Landlord's income taxes
     and income tax accounting, (d) interest and depreciation, (d) general
     corporate overhead, (e) capital improvements to the Building or Project
     except for capital improvements installed for the purpose of reducing or
     controlling expenses, or required by any governmental or other authority
     having or asserting jurisdiction over the Building or Project provided
     that the cost of such improvements shall be allocated over the useful life
     of such improvements, (f) space planning expenses, (g) promotional
     expenses, (h) rent abatements and lease takeover expenses, (i) costs of
     electricity outside normal business hours sold to tenants of the Building
     by Landlord for which Landlord is entitled to reimbursement from such
     tenants as an additional charge, (j) costs incurred by Landlord in
     connection with bringing the Building into compliance with all applicable
     codes and other laws to the extent such requirements were in existence as
     of the date of this Lease, and (k) salaries and benefits of employees of
     Landlord and its affiliates above the grade of Building or Project
     manager. If any expense, though paid in one year, relates to more than one
     calendar year, at option of Landlord, such expense may be proportionately
     allocated among such related calendar years.

     Cook County real estate taxes are payable in arrears for the preceding
     calendar year. For purposes of determining taxes for any given calendar
     year, the amount to be included for such year (a) from special assessments
     payable in installments, shall be the amount of the installments (and any
     interest) due and payable during such calendar year, (b) from all other
     taxes, shall be the amount accrued, assessed or otherwise imposed for such
     calendar year without regard to when any such taxes are payable, and (c)
     from any adjustment to any taxes by the taxing authority, when such
     adjustment has resulted in a corresponding adjustment payment by or to
     Landlord, shall constitute an adjustment to taxes for the calendar year
     during which such adjustment is made or received by Landlord, as the case
     may be. Notwithstanding any other provision contained in this Lease, taxes
     shall also include all reasonable costs and expenses (including, without
     limitation, reasonable legal, tax consultants, and appraisal fees and
     court costs) charged for the protest or the reduction of any of the
     aforesaid taxes, whether or not such protest or reduction is ultimately
     successful.

     In the event that the Building is not at least 95% leased during any
     calendar year, Landlord may make appropriate adjustments to those
     Operating Costs which vary with occupancy of the Building, using
     reasonable projections, to adjust such costs to an amount that would
     normally be expected to be incurred if the Building were 95% leased, and
     such adjusted costs shall be used for purposes of this Section 3.3. Such
     adjustment shall not apply to any calendar year during the Lease Term if
     such adjustment was not made during the Base Year, and in no event shall
     any such adjustment exceed 100% of actual Operating Costs.

     b. Tenant shall pay, in equal monthly installments, Tenant's Pro Rata Share
     of any estimated Excess Operating Costs for each calendar year which falls
     (in whole or in part) during the Lease Term (prorated for any partial
     calendar year at the beginning or end of the Lease Term). From time to time
     (but not more than annually), based on actual and

                                       5

<PAGE>

     projected Operating Cost data, Landlord may adjust its estimate of
     Operating Costs upward or downward. Within thirty (30) days after notice to
     Tenant of a revised estimate of Operating Costs, Tenant shall remit to
     Landlord a sum equal to any shortage of the amount which should have been
     paid to date for the then current calendar year based on the revised
     estimate, and all subsequent monthly estimated payments shall be based on
     the revised estimate.

     c.   As soon as possible, after the first day of each year Landlord shall
     compute the actual Operating Costs for the prior calendar year, and shall
     give notice thereof to Tenant. Within thirty (30) days after receipt of
     such notice, Tenant shall pay any deficiency between estimated and actual
     in Tenant's Pro Rata Share of any Excess Operating Costs for the prior
     calendar year (prorated for any partial calendar year at the beginning or
     end of the Lease Term). In the event of overpayment by Tenant, Landlord
     shall apply the excess to the next payment of Rent when due, until such
     excess is exhausted or until no further payments of Rent are due, in which
     case, Landlord shall pay to Tenant the balance of such excess within thirty
     (30) days thereafter. Tenant or its representatives shall have the right,
     upon reasonable notice, to examine Landlord's books and records with
     respect to the Operating Costs at the management office during normal
     business hours at any time within thirty (30) days following the delivery
     by Landlord to Tenant of the notice of actual Operating Costs. Tenant shall
     have an additional ten (10) days to file any written exception to any of
     the Operating Costs. If such examination discloses that Tenant's Pro Rata
     Share of Excess Operating Costs was overstated by ten percent (10%) or
     more, then Landlord shall reimburse Tenant for the reasonable costs of such
     examination within thirty (30) days after receipt of an invoice for such
     costs.

     d.   Landlord maintains its records on an accrual accounting basis rather
     than a cash accounting basis for Operating Costs purposes, and therefore
     Operating Costs shall be deemed to have been paid when such expenses have
     accrued. Any adjustment of an item of Operating Costs included in a
     particular calendar year which results in a corresponding adjustment
     payment by or to Landlord shall constitute an adjustment to Operating Costs
     during the calendar year when such adjustment is made.

     3.4  TAXES:  In addition to Base Rent and other sums to be paid by Tenant
hereunder, Tenant shall reimburse Landlord, as additional Rent, on demand, any
taxes payable by Landlord (a) upon, measured by or reasonably attributable to
the cost or value of Tenant's equipment, fixtures and other personal property
located in the Leased Premises or by the cost or value of any leasehold
improvements made to the Leased Premises by Tenant or Landlord, regardless of
whether title to such improvements are held by Tenant or Landlord; (b) upon or
measured by the monthly rental payable hereunder, including, without
limitation, any gross receipts tax or excise tax; (c) upon or with respect to
the possession, leasing, operation, management, maintenance, alteration,
repair, use or occupancy by Tenant of the Leased Premises or any portion
thereof; (d) upon this Lease or any document to which Tenant is a party
creating or transferring an interest or an estate in the Leased Premises. The
foregoing taxes shall not be included as part of Operating Costs to the extent
that Tenant is directly reimbursing Landlord therefor. Further, in no event
shall the foregoing taxes include Landlord's income taxes.

constructed in the Leased Premises as described in the Work Letter attached
hereto as SCHEDULE 6 (the "LEASEHOLD IMPROVEMENTS"). The expenses to be

Improvements are specified in SCHEDULE 6. Tenant and its contractors may enter
the Leased Premises as of the date that Tenant executes this Lease, prior to

Improvements. Tenant agrees that any such entry into the Leased Premises shall
be deemed to be subject to all of the terms, conditions, covenants and
provisions of this Lease (including, without limitation, the provisions of
SCHEDULE 6), except as to the covenant to pay Base Rent and Tenant's Pro Rata
Share of Operating Costs.

     4.2  CONDITION OF LEASED PREMISES: Except as expressly provided in SCHEDULE
6 attached hereto, Tenant acknowledges and agrees that it shall take possession
of and accepts the Leased Premises in an "as is" condition, without any warranty
as to the condition thereof. Upon the Lease Commencement Date or as soon
thereafter as is practicable, Tenant shall execute and deliver to Landlord a
letter in the form attached as SCHEDULE 7, acknowledging the Lease Commencement
Date. No agreement of Landlord, the Managing Agent or their respective agents or
employees to alter, remodel, decorate, clean or improve the Leased Premises (or
to provide Tenant with any credit or allowance for the same), and no
representation regarding the condition of the Leased Premises, has been made by
or on behalf of Landlord or such other parties or relied upon by Tenant, except
as stated in the Work Letter attached as SCHEDULE 6.

                                PROJECT SERVICES

     5.1  PROJECT SERVICES: Landlord shall furnish the following Project
     Services:

     a.   Utility Services:  Landlord shall provide the utility services listed
     on SCHEDULE 3 (the "UTILITY SERVICES"). Electric power for Tenant lighting
     and operating of office machines is separately metered and billed by
     Commonwealth Edison.

     b.   Maintenance Services:  Landlord shall provide maintenance of all
     interior and exterior common areas of the Building including lighting,
     landscaping, cleaning, painting, maintenance and repair of the exterior of
     the Building and its structural portions and roof, including but not
     limited to all of the services listed on SCHEDULE 4 (the "MAINTENANCE
     SERVICES").

     c.   Parking:  Landlord shall provide the reserved parking spaces as
     provided in Section 1.1(j). In addition, Tenant shall be entitled to use,
     without charge and in common with the other tenants of the Project,
     non-reserved parking spaces at the Project based on 3.1 parking spaces per
     1,000 square feet of the Leased Premises as of the Lease Commencement Date
     (such reserved and non-reserved parking spaces being referred to
     collectively as the "PARKING"). Tenant acknowledges that the terms and
     conditions

                                       7

<PAGE>
     described in SCHEDULE 5 attached hereto shall apply to Tenant's use of the
     Parking under this Lease.

     The Utility Services, the Maintenance Services and Parking described above
shall be collectively referred to as "PROJECT SERVICES". The costs of Project
Services shall be a part of Operating Costs.

     5.2 INTERRUPTION OF SERVICES: Landlord does not warrant that any of the
Project Services will be free from interruption. Any Project Service may be
suspended by reason of accident or of necessary repairs, alternations or
improvements, or by strikes or lockouts, or by reason of operation of law, or
causes beyond the reasonable control of Landlord. Subject to possible rent
abatement as may be provided pursuant to the conditions described in Section
8.1, any such interruption or discontinuance of such Project Services shall
never be deemed a disturbance of Tenant's use and possession of the Leased
Premises, or render Landlord liable to Tenant for damages by abatement of rent
or otherwise, or relieve Tenant from performance of Tenant's obligations under
this Lease; provided, however, that should such interruption or discontinuance
of Project Services which materially impairs Tenant's ability to conduct its
business continue for four (4) consecutive business days, then beginning on
the fifth business day, Landlord shall abate Base Rent and Tenant's Pro Rata
Share of Excess Operating Costs, for that portion of the Leased premises
rendered untenantable, from the fifth business day after said interruption or
discontinuance until the Project Services are restored. In addition,
notwithstanding anything to the contrary contained herein. if any such
interruption or discontinuance of Project Services shall occur as a result of a
condition which affects on the Project (and does not affect office buildings in
general in the Chicago-O'Hare area), and if (i) such interruption or
discontinuance is within Landlord's reasonable control, (ii) such interruption
or discontinuance does not arise as a result of an act or omission of Tenant,
(iii) as a result of such interruption or discontinuance, the Leased Premises
is rendered untenantable and Tenant in fact so ceases to use the Leased
Premises for significant business operations, and (iv) such interruption or
discontinuance continues for a period of ninety (90) consecutive days, then
Tenant shall have the right to terminate this Lease by prior written notice to
Landlord given within thirty (30) days after the expiration of such period (but
prior to any restoration of Project Services), which termination shall be
effective as of the date of such notice.

                                       8

<PAGE>

     Project. Nothing contained herein shall require Tenant to be responsible
     for violations with any of the foregoing to the extent such violations
     existed as of the date of this Lease.

     c. Nuisances or Waste: Tenant shall not do or permit anything to be done in
     or about the Leased Premises, or bring or keep anything in the Leased
     Premises that may increase Landlord's fire and extended coverage insurance
     premium, damage the Building or the Project, constitute waste, constitute
     an immoral purpose, or be a nuisance, public or private, or menace or other
     disturbance to tenants of adjoining premises or anyone else.

     d. Hazardous Substances: Tenant shall (i) comply with all Environmental
     Laws; (ii) not cause or permit any Hazardous Materials to be treated,
     stored, disposed of, generated, or used in the Leased Premises or the
     Project, provided, however, that Tenant may store, use or dispose of
     products customarily found in offices and used in connection with the
     operation and maintenance of property if Tenant complies with all
     Environmental Laws and does not contaminate the Leased Premises, Project or
     environment; (iii) promptly after receipt, deliver to Landlord any
     communication concerning any past or present, actual or potential violation
     of Environmental Laws, or liability of either party for Environmental
     Damages. "ENVIRONMENTAL LAWS" mean all applicable present and future
     statutes, regulations, rules, ordinances, codes, permits or orders of all
     governmental agencies, departments, commissions, boards, bureaus, or
     instrumentalities of the United States, states and their political
     subdivisions and all applicable judicial, administrative and regulatory
     decrees and judgments relating to the protection of public health or safety
     or of the environment. "HAZARDOUS MATERIALS" include substances (1) which
     require remediation under any Environmental Laws; or (2) which are or
     become defined as a "hazardous waste", "hazardous substance", pollutant or
     contaminant under any Environmental Laws; or (3) which are toxic,
     explosive, corrosive, flammable, infectious, radioactive, carcinogenic or
     mutagenic; or (4) which contain petroleum hydrocarbons, polychlorinated
     biphenyls, asbestos, asbestos containing materials or urea formaldehyde.
     "ENVIRONMENTAL DAMAGES" means all claims, judgments, losses, penalties,
     fines, liabilities, encumbrances, liens, costs and reasonable expenses of
     investigation, defense or good faith settlement resulting from violations
     of Environmental Laws, and including, without limitation: (A) damages for
     personal injury and injury to property or natural resources; (B) reasonable
     fees and disbursement of attorneys, consultants, contractors, experts and

     abatement, containment, closure, restoration or monitoring work required by
     any Environmental Law and other costs reasonably necessary to restore full
     economic use of the Leased Premises or Project.

     e. Alterations and Improvements: Tenant shall make no alterations or
     improvements to the Leased Premises without the prior written approval of
     Landlord (which approval shall not be unreasonably withheld or delayed) and
     Landlord's mortgagee, if any. Notwithstanding the foregoing, Tenant shall
     have the right, without the necessity of obtaining Landlord's consent, to
     make non-structural, decorative alterations or improvements to the Leased
     Premises, the cost of which shall not exceed $25,000.00 in the aggregate
     and the performance of which does not require the issuance of a building
     permit under applicable building codes and ordinances. Any such alterations
     or improvements by Tenant shall be done in a good and workmanlike manner,
     at Tenant's

                                       9
<PAGE>

     expense, by a licensed contractor approved by Landlord and in conformity
     with plans and specifications approved by Landlord. Landlord shall have the
     right to supervise any alterations or improvements for which Landlord's
     consent is required, in which event Tenant shall pay to Landlord on demand
     a fee for such supervision in an amount equal to five percent (5%) of the
     cost of such alterations or improvements (exclusive of "soft costs"). If
     requested by Landlord, Tenant will post a bond or other security reasonably
     satisfactory to Landlord to protect Landlord against liens arising from
     work performed for Tenant. Landlord's approval of the plans and
     specifications for Tenant's alterations or improvements shall create no
     responsibility or liability on the part of Landlord for their completeness,
     design sufficiency, or compliance with all laws, rules and regulations of
     governmental agencies or authorities.

     f.  Liens: Tenant shall keep the Leased Premises, the Building and the
     Project free from liens arising out of any work performed, materials
     furnished or obligations incurred by or for Tenant. If, at any time, a lien
     or encumbrance is filed against the Leased Premises, the Building or the
     Project as a result of Tenant's work, materials or obligations, Tenant
     shall promptly discharge such lien or encumbrance. If such lien or
     encumbrance has not been removed within thirty (30) days from the date it
     is filed, Tenant agrees to deposit with Landlord cash or a bond, which
     shall be in a form and be issued by a company acceptable to Landlord in its
     sole discretion, in an amount equal to 150% of the amount of the lien, to
     be held by Landlord as security for the lien being discharged.

     g.  Rules and Regulations: Tenant shall observe, perform and abide by all
     the rules and regulations promulgated by Landlord from time to time.
     SCHEDULE 2 sets forth Landlord's rules and regulations in effect on the
     date hereof.

     h.  Signage: Tenant shall obtain the prior approval of the Landlord (which
     approval shall not be unreasonably withheld or delayed) before placing any
     sign or symbol in doors or windows or elsewhere in or about the Leased
     Premises, or upon any other part of the Building, or Project including
     building directories. Any signs or symbols which have been placed without
     Landlord's approval may be removed by Landlord. Upon expiration or
     termination of this Lease, all signs installed by Tenant shall be removed
     and any damage resulting therefrom shall be promptly repaired, or such
     removal and repair may be done by Landlord and the cost charged to Tenant
     as Rent.

     6.2  INSURANCE: Tenant shall, at its own expense, procure and maintain
during the Lease Term: (i) all risk insurance, including coverage for loss or
damage resulting from water (exclusive of flood insurance) or theft, on
merchandise, trade fixtures, and personal property owned by the Tenant, and
property of others in the Tenant's possession, on a full replacement cost and
agreed value basis, and (ii) worker's compensation insurance in at least the
statutory amounts, and (iii) commercial general liability insurance with respect
to the Leased Premises and Tenant's activities in the Leased Premises and in the
Building and the Project, providing bodily injury, personal injury, contractual
liability, and property damage coverage with a maximum $5,000 deductible, or
such other amount approved by the Landlord, in writing, and minimum coverage
limits as follows:

                                       10
<PAGE>

     a. $2,000,000 with respect to bodily injury or death, personal injury,
     contractual liability and property damage arising out of any one
     occurrence;

     Nothing in this Section 6.2 shall prevent Tenant from obtaining insurance
of the kind and in the amounts provided for under this paragraph under a blanket
insurance policy covering other properties as well as the Leased Premises,
provided, however, that any such policy of blanket insurance (i) shall specify
the amounts of the total insurance allocated to the Leased Premises, which
amounts shall not be less than the amounts required by subparagraph a. above,
and (ii) such amounts so specified shall be sufficient to prevent any one of the
assureds from becoming a coinsurer within the terms of the applicable policy,
and (iii) shall, as to the Leased Premises, otherwise comply as to endorsements
and coverage with the provisions of this paragraph. Tenant's insurance shall be
with a company which has a rating equal to or greater than Best's Insurance
Reports classification of A, Class X or its equivalent, as such classification
is determined as of the Lease Commencement Date. Landlord and Landlord's
mortgagee, if any, shall be named as "additional insureds" under Tenant's
general liability insurance, and such Tenant's insurance shall be primary and
non-contributing with Landlord's insurance. Tenant's insurance policies shall
contain endorsements requiring 30 days notice to Landlord and Landlord's
mortgagee, if any, prior to any cancellation, lapse or nonrenewal or any
reduction in amount of coverage.

Tenant shall deliver to Landlord as a condition precedent to its taking
occupancy of the Leased Premises, certificates of Insurance for all required
insurance obligations hereunder including evidence of contractual liability and
additional insured status on a primary and non-contributing basis with respect
to liability coverage, or certified copies of any of the policies evidencing
such insurance obligations.

Landlord shall, at its own expense, procure and maintain during the Lease Term
fire and extended coverage insurance for 100% replacement value of the
Building, including all improvements and fixtures thereto.

     6.3 REPAIRS:  Tenant, at its sole expense, agrees to maintain the interior
of the Leased Premises in a neat, clean and sanitary condition. If Tenant fails
to maintain or keep the Leased Premises in good repair and such failure
continues for five (5) days after written notice from Landlord or if such
failure results in a nuisance or health or safety risk, Landlord may perform
any such required maintenance and repairs and the cost thereof shall be payable
by Tenant as Rent within ten (10) days of receipt of an invoice from Landlord.
Tenant shall also pay to Landlord the costs of any repair to the Building or
Project necessitated by any act or neglect of Tenant.

     6.4 ASSIGNMENT AND SUBLETTING:  Tenant shall not assign, mortgage, pledge,
or encumber this Lease, or permit all or any part of the Leased Premises to be
subleased without the prior written consent of Landlord and Landlord's
mortgagee, if any, which consent shall not be unreasonably withheld or delayed.
Any transfer of this Lease by merger, consolidation, reorganization or
liquidation of Tenant, or by operation of law, or change in ownership of or
power to vote the majority of the outstanding voting stock of a corporate
Tenant, or by change in ownership of a controlling partnership interest in a
partnership Tenant, shall constitute an assignment for the purposes of this
paragraph. Notwithstanding the foregoing, Tenant shall have

                                       11

<PAGE>

the right to assign or sublease part or all of the Lease Premises to any of its
subsidiaries, affiliates or any parent corporation of Tenant with prior written
notice to Landlord provided that (i) Tenant continues to be primarily liable on
its obligations as set forth herein; (ii) any such assignee or sublessee shall
assume and be bound by all covenants and obligations of Tenant herewith;
(iii) the proposed assignee or sublessee is, in Landlord's good faith
judgment, compatible with other tenants in the Building and seeks to use the
Leased Premises only for the Permitted Purpose and for a use that is not
prohibited under the terms of a lease with another tenant in the Building; and
(iv) such use would not result in a material change in the number of personnel
working in, or members of the general public visiting, the Leased Premises.

     In addition to other reasonable bases, Tenant hereby agrees that Landlord
shall be deemed to be reasonable in withholding its consent, if: (a) such
proposed assignment or sublease is to any party who is then a tenant of the
Building or the Project if Landlord has comparable area; or (b) Tenant is in
default under any of the terms, covenants, conditions, provisions and agreements
of this Lease at the time of request for consent or on the effective date of
such subletting or assignment; or (c) the proposed subtenant or assignee is, in
Landlord's good faith judgment, incompatible with other tenants in the Building,
or seeks to use any portion of the Leased Premises for a use not consistent with
other uses in the Building, or is financially incapable of assuming the
obligations of this Lease; or (d) the proposed assignee of sublessee or its
business is subject to compliance with additional requirements of the law
(including related regulations) commonly known as the "Americans with
Disabilities Act" beyond those requirements which are applicable to the Tenant,
unless the proposed assignee of sublessee shall: (i) first deliver plans and
specifications for complying with such additional requirements and obtain
Landlord's consent thereto, and (ii) comply with all Landlord's conditions for
or contained in such consent, including without limitation, requirements for
security to assure the lien-free completion of such improvements. Tenant shall
submit to Landlord the name of a proposed assignee or subtenant, the terms of
the proposed assignment or subletting, a copy of the proposed assignment
document or sublease, the nature of the proposed subtenant's business and such
information as to the assignee's or subtenant's financial responsibility and
general reputation as Landlord may reasonably require.

     No subletting or assignment, even with the consent of Landlord, shall
relieve Tenant of its primary obligation to pay the Rent and to perform all of
the other obligations to be performed by Tenant hereunder. The acceptance of
Rent by Landlord from any other person or entity shall not be deemed to be
waiver by Landlord of any provision of this Lease or to be a consent to any
assignment, subletting or other transfer. Consent to one assignment, subletting
or other transfer shall not be deemed to constitute consent to any subsequent
assignment, subletting or transfer.

     In lieu of giving any consent to a sublet or an assignment of all the
Leased Premises, Landlord may, at Landlord's option, elect to terminate this
Lease. In the case of a proposed subletting of a portion of the Leased Premises,
Landlord may, at Landlord's option, elect to terminate the Lease with respect to
that portion of the Leased Premises being proposed for subletting. The effective
date of any such termination shall be thirty (30) days after the proposed
effective date of any proposed assignment or subletting.

     Fifty percent (50%) of any proceeds in excess of Base Rent and Tenant's Pro
Rata Share of Excess Operating Costs which is received by Tenant pursuant to an
assignment or subletting

                                       12
<PAGE>

consented to by Landlord, less reasonable brokerage commissions actually paid by
Tenant, and less other costs incurred by Tenant in connection with making the
space available for lease, shall be remitted to Landlord as extra Rent within
thirty (30) days of receipt by Tenant. For purposes of this paragraph, all money
or value in whatever form received by Tenant from or on account of any party as
consideration for an assignment or subletting (except for the sale of Tenant's
personal property and inventory at its then reasonable market value) shall be
deemed to be proceeds received by Tenant pursuant to an assignment or
subletting.

     6.5  ESTOPPEL CERTIFICATE:  From time to time and within ten (10) days
after request by Landlord, Tenant shall execute and deliver a certificate to
any proposed lender or purchaser, or to Landlord, together with a true and
correct copy of this Lease, certifying with any appropriate exceptions, (i)
that this Lease is in full force and effect without modification or amendment,
(ii) the amount of Rent payable by Tenant and the amount, if any, of Prepaid
Rent and Deposit paid by Tenant to Landlord, (iii) the nature and kind of
concessions, rental or otherwise, if any, which Tenant has received or is
entitled to receive, (iv) that Tenant has not assigned its rights under this
Lease or sublet any portion of the Leased Premises, (v) that Landlord has
performed all of its obligations due to be performed under this Lease and that
there are no defenses, counterclaims, deductions or offsets outstanding or
other excuses for Tenant's performance under this Lease, (vi) that such
proposed lender or purchaser may rely on the information contained in the
certificate, and (vii) any other fact reasonably requested by Landlord or such
proposed lender or purchaser.

                           LANDLORD'S RESERVED RIGHTS

     7.1  INTENTIONALLY OMITTED

     7.2  ADDITIONAL RIGHTS RESERVED TO LANDLORD:  Without notice and without
liability to Tenant or without effecting an eviction or disturbance of Tenant's
use or possession, Landlord shall have the right to (i) grant utility easements
or other easements in, or replat, subdivide or make other changes in the legal
status of the land underlying the Building or the Project as Landlord shall
deem appropriate in its sole discretion, provided such changes do not
substantially interfere with Tenant's use of the Leased Premises for the
Permitted Purpose; (ii) enter the Leased Premises at reasonable times
upon reasonable prior notice (or, in the event of an emergency, at any time and
without notice) to inspect, alter or repair the Leased Premises or the Building
and to perform any acts related to the safety, protection, reletting, sale or
improvement of the Leased Premises or the Building; (iii) change the name or
street address of the Building or the Project; (iv) install and maintain signs
on and in the Building and the Project; and (v) make such rules and regulations
as, in the sole judgment of Landlord, may be needed from time to time for the
safety of the tenants, the care and cleanliness of the Leased Premises, the
Building and the Project and the preservation of good order therein.

                                 ARTICLE EIGHT
                          CASUALTY AND UNTENANTABILITY

     8.1  CASUALTY AND UNTENANTABILITY:  If the Building is made substantially
untenantable or it Tenant's use and occupancy of the Leased Premises are
substantially interfered

                                       13
<PAGE>
with due to damage to the common areas of the Building or if the Leased
Premises are made wholly or partially untenantable by fire or other casualty,
Landlord may, by notice to Tenant within forty-five (45) days after the damage,
terminate this Lease. Such termination shall become effective as of the date of
such casualty.

     If the Leased Premises are made partially or wholly untenantable by fire
or other casualty and this Lease is not terminated as provided above, Landlord
shall restore the Leased Premises to the condition they were in on the Lease
Commencement Date, not including any personal property of Tenant or alterations
performed by Tenant (other than the initial Leasehold Improvements).

     If the Landlord does not terminate this Lease as provided above, and
Landlord fails within one hundred twenty (120) days from the date of such
casualty to restore the damaged common areas thereby eliminating substantial
interference with Tenant's use and occupancy of the Leased Premises, or fails to
restore the Leased Premises to the condition they were in on the Lease
Commencement Date, not including any personal property or alterations performed
by Tenant (other than the initial Leasehold Improvements), Tenant may terminate
this Lease as of the end of such one hundred twenty (120) day period.

     Notwithstanding anything to the contrary contained herein, the parties
hereto acknowledge and agree that, to the extent any Superior Instrument (as
defined in Section 13.4 below) conflicts with the terms of this Article 8, the
terms of such Superior Instrument shall control with respect to the
disbursement and application of insurance proceeds, and that Landlord will
comply with all requirements of the holder of any such Superior Instrument to
deposit such insurance proceeds in escrow pending the application and
disbursement of such insurance proceeds.

     In the event of termination of this Lease pursuant to this section, Rent
shall be prorated on a per diem basis and paid to the date of the casualty,
unless the Leased Premises shall be tenantable, in which case Rent shall be
payable to the date of the lease termination. If the Leased Premises are
untenantable and this Lease is not terminated, Rent shall abate on a per diem
basis from the date of the casualty until the Leased Premises are ready for
occupancy by Tenant. If part of the Leased Premises are untenantable, Rent
shall be prorated on a per diem basis and apportioned in accordance with the
part of the Leased Premises which is usable by Tenant until the damaged part is
ready for Tenant's occupancy. Notwithstanding the foregoing, if any damage was
proximately caused by an act or omission of Tenant, its employees, agents,
contractors, licensees or invitees, then, in such event, Tenant agrees that
Rent shall not abate or be diminished during the term of this Lease.

                                  ARTICLE NINE
                                  CONDEMNATION

     9.1 CONDEMNATION: If all or any part of the Leased Premises shall be taken
under power of eminent domain or sold under imminent threat to any public
authority or private entity having such power, this Lease shall terminate as to
the part of the Leased Premises so taken or sold, effective as of the date
possession is required to be delivered to such authority. In such event, Base
Rent shall abate in the ratio that the portion of Tenant's Square Footage taken
or sold

                                       14
<PAGE>

bears to Tenant's Square Footage. If a partial taking or sale of the Leased
Premises, the Building or the Project (i) substantially reduces Tenant's Square
Footage resulting in a substantial inability of Tenant to use the Leased
Premises for the Permitted Purpose, or (ii) renders the Building or the Project
not commercially viable to Landlord in Landlord's sole opinion, either Tenant in
the case of (i), or Landlord in the case of (ii), may terminate this Lease by
notice to the other party within thirty (30) days after the terminating party
receives written notice of the portion to be taken or sold. Such termination
shall be effective one hundred eighty (180) days after notice thereof, or when
the portion is taken or sold, whichever is sooner. All condemnation awards and
similar payments shall be paid and belong to Landlord, except any amounts
awarded or paid specifically to Tenant for removal and reinstallation of
Tenant's trade fixtures, personal property or Tenant's moving costs.

                             WAIVER AND INDEMNITY

     10.1 LIABILITY WAIVER:  Except for those claims arising from the
Landlord's negligence or willful misconduct, Tenant, to the extent permitted by
law, hereby releases Landlord and waives any right of recovery or subrogation
for injury to persons or damage to property sustained by any third person
(including employees), firm, or corporation against which Tenant is provided
protection by the insurance coverage afforded Tenant through any Liability or
Workers' Compensation Insurance Policies. Tenant agrees that such policies of
insurance shall contain appropriate waiver of subrogation and right of recovery
clauses (for property perils and damage only).

     10.2 INDEMNIFICATION:

     a.   Tenant agrees that Tenant will indemnify and hold and save Landlord
     whole and harmless of, from and against all suits, losses, costs,
     liabilities, claims demands, actions, expenses and judgments of every kind
     and character suffered by, recovered from or asserted against Landlord on
     account of injury or damage to person or property to the extent that any
     such damage or injury may be incident to, arise out of, or be caused,
     either proximately or remotely, by an act, omission, negligence, or
     misconduct on the part of the Tenant or any of its agents, servants,
     employees, contractors, patrons, guests, licensees, or invitees or of any
     other reason entering upon the Leased Premises under or with the express or
     implied invitation or permission of Tenant or when any such injury or
     damage is the result, proximate or remote, of the violation by Tenant or
     any of its agents, servants, employees, contractors, patrons, guests,
     licensees or invitees of any law, ordinance, or governmental order, or when
     any such injury or damage may in any other way arise from or out of the
     occupancy or use by Tenant, its agents, servants, employees, contractors,
     patrons, guests, licensees or invitees of the Leased Premises, except to
     the extent caused by Landlord's negligence or willful misconduct or by any
     of Landlord's agents, servants, employees, contractors, patrons, guests,
     licensees or invitees. Tenant agrees to indemnify, defend, reimburse and
     hold Landlord harmless against any Environmental Damages incurred by
     Landlord arising from Tenant's breach of Section 6.1(d) of the Lease.

                                       15

<PAGE>

     b.  Landlord agrees to hold Tenant harmless and indemnified against claims
     and liability for injuries to all persons and for damage to or loss of
     property occurring in or about the Leased Premises or the Building due to
     Landlord's breach of this Lease or due to the negligence of Landlord, its
     contractors, agents, employees, licensee or invitees.

     10.3  WAIVER OF SUBROGATION: In the event of fire or other loss to the
Leased Premises or the Building, Tenant and Landlord release each other and
waive any right of subrogation or recovery against each other for loss or
damage to the waiving party or its respective property, which occurs in or
about the Leased Premises or Building, whether due to the negligence of either
party, their agents, employees, officers, contractors licensees, invitees or
otherwise, to the extent that such loss or damage is insurable against under
the terms of the insurance contracts required hereunder. Tenant and Landlord
agree that all policies of insurance obtained by either of them in connection
with the Leased Premises shall contain appropriate waiver of subrogation
clauses.

     10.4  LIMITATION OF LANDLORD'S LIABILITY: The obligations of Landlord
under this Lease do not constitute personal obligations of the individual
partners, shareholders, directors, officers, employees or agents of Landlord,
and Tenant shall look solely to Landlord's interest in the Building and land
and to no other assets of Landlord for satisfaction of any liability in respect
of this Lease. Tenant will not seek recourse against the individual partners,
shareholders, directors, officers, employees or agents of Landlord or any of
their personal assets for such satisfaction. Notwithstanding any other
provisions contained herein, Landlord shall not be liable to Tenant, its
contractors, agents or employees for any consequential damages or damages for
loss of profits.

                                 ARTICLE ELEVEN
                    TENANT'S DEFAULT AND LANDLORD'S REMEDIES

     11.1  TENANT'S DEFAULT: It shall be an "EVENT OF DEFAULT" if Tenant shall
(i) fail to pay any monthly installment of Base Rent or Tenant's Pro Rata
Share of Excess Operating Costs, or any other sum payable hereunder within ten

any of the other conditions, covenants or agreements herein made by Tenant, and
such violation or failure shall continue for fifteen (15) days after written
notice thereof to Tenant by Landlord; provided, however, if such default is of

not be an Event of Default if Tenant commences to cure within such fifteen (15)
day period and diligently prosecutes such cure to completion within the time
reasonably required for such cure, not to exceed sixty (60) days; (iv) make a
general assignment for the benefit of its creditors or file a petition for
bankruptcy or other reorganization, liquidation, dissolution or similar relief;
(v) have a proceeding filed against Tenant seeking any relief mentioned in (iv)
above; (vi) have a trustee, receiver or liquidator appointed for Tenant or a
substantial part of its property; (vii) abandon or vacate the Leased Premises
and any portion of Rent is delinquent; (viii) default under any other lease, if
any, within the Building or the Project; or (ix) if Tenant is a partnership, if
any partner of

                                       16

<PAGE>

the partnership is involved in any of the acts or events described in
subparagraphs (i) through (viii) above.

     11.2 REMEDIES OF LANDLORD: If an Event of Default occurs, Landlord, may, at
its option, five (5) days after written notice to Tenant, reenter the Leased
Premises, remove all persons therefrom, take possession of the Leased Premises,
and remove all of Tenant's personal property at Tenant's risk and expense and,
either (i) terminate this Lease and Tenant's right of possession of the Leased
Premises or (ii) maintain this Lease in full force and effect and endeavor to
relet all or part of the Leased Premises. In the event Landlord elects to
maintain this Lease, Landlord shall have the right to relet the Leased Premises
for such rent and upon such terms as Landlord deems reasonable and necessary,
and Tenant shall be liable for all damages sustained by Landlord, including but
not limited to, any deficiency in Rent for the period of time which would have
remained in the Lease Term in the absence of any termination, leasing fees,
attorneys' fees, other marketing and collection costs, the cash value of any
concessions granted to Tenant and all expenses of placing the Leased Premises in
first class rentable condition. Landlord retains the right to terminate this
Lease, at any time, notwithstanding that Landlord fails to terminate this Lease
initially. If Landlord is unable after diligent efforts to relet the Leased
Premises within one hundred twenty (120) days after termination of this Lease,
Landlord may elect at any time thereafter to have Tenant immediately pay, as
liquidated damages and not as a penalty, all Rent then due and the present value
(discounted at 10%) of all Rent which would have become due (based on Base Rent
and Tenant's Pro Rata Share of Excess Operating Costs payable at the time of
such election and the cash value of any concessions granted to Tenant) for the
period of time which would have remained in the Lease Term in the absence of any
termination over the then reasonable rental value of the Leased Premises for the
remaining Lease Term. Notwithstanding anything to the contrary contained herein,
Landlord agrees to use commercially reasonable efforts to mitigate its damages
following an Event of Default by Tenant.

The remedies granted to Landlord herein shall be cumulative and shall not
exclude any other remedy allowed by law, and shall not prevent the enforcement
of any claim Landlord may have against Tenant for anticipatory breach of the
unexpired term of this Lease, including without limitation, a claim for
attorney's fees incurred by Landlord.

                                 ARTICLE TWELVE
                                  TERMINATION

     12.1 SURRENDER OF LEASED PREMISES: On expiration of this Lease, if no Event
of Default exists, Tenant shall surrender the Leased Premises in the same
condition as when the Lease Term commenced, ordinary wear and tear or damage
from casualty excepted. Except for furnishings, trade fixtures and other
personal property installed at Tenant's expense, all alterations, additions or
improvements, whether temporary or permanent in character, made in or upon the
Leased Premises, either by Landlord or Tenant, shall be Landlord's property and
at the expiration or earlier termination of the Lease Term shall remain on the
Leased Premises without compensation to Tenant, except if requested by Landlord,
Tenant, at its expense and without delay, shall remove any alterations,
additions or improvements made to the Leased Premises by Tenant designated by
Landlord to be removed (such designation by Landlord shall occur at the time
Landlord consents to such improvements), and repair any damage to the Leased

                                       17

<PAGE>

Premises or the Building caused by such removal. If Tenant fails to repair the
Leased Premises, Landlord may complete such repairs and Tenant shall reimburse
Landlord for such repair and restoration. Landlord shall have the option to
require Tenant to remove all its property. If Tenant fails to remove such
property as required under this Lease, Landlord may dispose of such property in
its sole discretion without any liability to Tenant, and further may charge the
cost of any such disposition to Tenant.

     12.2 HOLD OVER TENANCY: If Tenant shall hold over after the Lease
Expiration Date, Tenant may be deemed, and Landlord's option, to occupy the
Leased Premises as a tenant from month to month, which tenancy may be
terminated by one month's written notice. During such tenancy, Tenant agrees to
pay to Landlord, monthly in advance, an amount equal to 150%, for the first
thirty (30) days of such tenancy, and 200% thereafter; of all Rent which would
become due (based on Base Rent and Tenant's Pro Rata Share of Excess Operating
Costs payable for the last month of the Lease Term, together with all other
amounts payable by Tenant to Landlord under this Lease), and to be bound by all
of the terms, covenants and conditions herein specified. If Landlord relets the
Leased Premises or any portion thereof to a new tenant and the term of such new
lease commences during the period for which Tenant holds over, Landlord shall
also be entitled to recover from Tenant all costs and expenses, attorneys fees,
damages or loss of profits incurred by Landlord as a result of Tenant's failure
to deliver possession of the Leased Premises to Landlord when required under
this Lease.

                                ARTICLE THIRTEEN
                                 MISCELLANEOUS

     13.1 QUIET ENJOYMENT: If and so long as Tenant pays all Rent and keeps and
performs each and every term, covenant and condition herein contained on the
part of Tenant to be kept and performed, Tenant shall quietly enjoy the Leased
Premises without hindrance by Landlord.

     13.2 ACCORD AND SATISFACTION: No receipt and retention by Landlord of any
payment tendered by Tenant in connection with this Lease shall constitute an
accord and satisfaction, or a compromise or other settlement, notwithstanding
any accompanying statement, instruction or other assertion on the contrary
unless Landlord expressly agrees to an accord and satisfaction, or a compromise
or other settlement, in a separate writing duly executed by Landlord. Landlord
will be entitled to treat any such payments as being received on account of any
item or items of Rent, interest, expense or damage due in connection herewith,
in such amounts and in such order as Landlord may determine at its sole option.

     13.3 SEVERABILITY: The parties intend this Lease to be legally valid and
enforceable in accordance with all of its terms to the fullest extent permitted
by law. If any term hereof shall be invalid or unenforceable, the parties agree
that such term shall be stricken from this Lease to the extent unenforceable,
the same as if it never had been contained herein. Such invalidity or
unenforceability shall not extend to any other term of this Lease, and the
remaining terms hereof shall continue in effect to the fullest extent permitted
by law, the same as if such stricken term never had been contained herein.

     13.4  SUBORDINATION AND ATTORNMENT: Tenant acknowledges that this Lease is
subject and subordinate to all leases in which Landlord is lessee and to any
mortgage or deed of trust now in force against the Building and to all advances
made or hereafter to be made thereunder, or any amendments or modifications
thereof, and shall be subordinate to any future leases in which Landlord is
lessee and to any future mortgage or deed of trust hereafter in force against
the Building and to all advances made or hereafter to be made thereunder (all
such existing and future leases, mortgages and deeds of trust referred to
collectively as "SUPERIOR INSTRUMENTS"). Tenant also agrees that if the holder
of any Superior Instrument elects to have this lease superior to its Superior
Instrument and gives notice of its election to Tenant, then this lease shall be
superior to the lien of any such lease, mortgage or deed of trust and all
renewals, replacements and extensions thereof, whether this Lease is dated
before or after such lease, mortgage or deed of trust. If requested in writing
by Landlord or any first mortgagee or ground lessor of Landlord, Tenant agrees
to execute a subordination agreement required to further affect the provisions
of this section. Notwithstanding anything to the contrary contained herein,
Landlord agrees to use commercially reasonable efforts to secure a
non-disturbance agreement from the holder of any Superior Instrument entered
into after the date of this Lease.

     In the event of any transfer in lieu of foreclosure or termination of a
lease in which Landlord is lessee or the foreclosure of any Superior Instrument,
or sale of the Property pursuant to any Superior Instrument, Tenant shall attorn
to such purchaser, transferee or lessor and recognize such party as landlord
under this Lease, provided such party acquires and accepts the Leased Premises
subject to this lease. The agreement of Tenant to attorn contained in the
immediately preceding sentence shall survive any such foreclosure sale or
transfer.

     13.5  ATTORNEY'S FEES: If the services of an attorney are required by any
party to secure the performance under this Lease or otherwise upon the breach
or default of the other party to the Lease, or if any judicial remedy is
necessary to enforce or interpret any provision of the Lease, the prevailing
party shall be entitled to reasonable attorney's fees, costs and other
expenses, in addition to any other relief to which such prevailing party may be
entitled.

pronouns in the singular number are uniformly used throughout this Lease
regardless of gender, number or fact of incorporation of the parties hereto.

     13.8  TIME: Time is of the essence of this Lease.

     13.9  ENTIRE AGREEMENT: This Lease and the schedules and addenda attached
set forth all the covenants, promises, agreements, representations, conditions,
statements and understandings between Landlord and Tenant concerning the Leased
Premises and the Building and the Project, and there are no representations,
either oral or written between them other than those in this Lease. This Lease
shall not be amended or modified except in writing signed by

                                       19
<PAGE>

both parties. Failure to exercise any right in one or more instances shall not
be construed as a waiver of the right to strict performance or as an amendment
to this Lease.

Lease shall be in writing and served on the parties at the addresses listed in
Section 1.1(n) and paragraph 1.1(o). Any notice shall be either (i) personally

and 1.1(o) may be changed by written notice to the other parties, provided,
however, that no notice of a change of address or Fax number shall be effective

indemnify and hold harmless the other party against any loss, cost, expense or
liability for any compensation, commission, fee or charge, including reasonable

conditions, express or implied, herein contained in favor of Tenant, and in such
event Tenant agrees to look solely to the responsibility of the successor in
interest of Landlord in and to this Lease provided that the transferee assumes
Landlord's obligations hereunder. This Lease shall not be affected by any such
sale, conveyance or transfer.

     13.14  RIGHT OF FIRST OFFER: If, at any time during the Term, Landlord
shall desire to lease any space comprising a part of Suite 450 on the fourth
floor of the Building, as depicted on SCHEDULE 1A (the "ROFO SPACE") to a third
party, other than the existing tenant in any such space, and provided that there
shall be no uncured Event of Default by Tenant under this Lease, Landlord shall
first give Tenant written notice ("LANDLORD'S NOTICE") of the Business Terms (as
hereinafter defined) upon which Landlord is planning to market the ROFO Space.
As used herein, "BUSINESS TERMS" means the lease term (the "ROFO TERM"), the

ROFO Space for purposes of the subject Landlord's Notice, or (ii) accept the
ROFO Space on the Business Terms set forth in Landlord's Notice. If Tenant
fails to deliver Tenant's Notice within such five (5) business day period,
Tenant shall be deemed to have waived its rights to the ROFO Space. If Tenant
timely elects to accept the ROFO Space, Landlord and Tenant shall, within thirty
30) days from the date of Tenant's Notice, enter into a lease amendment with
respect to the ROFO Space reflecting the Business Terms provided in Landlord's
Notice. In the event Tenant elects to waive its rights (or is deemed to have
waived its rights) as to any ROFO Space, Landlord shall have the absolute right
to lease the ROFO Space to any other person or entity on any terms and
conditions, and Tenant shall have no further rights with respect to the ROFO
Space, unless (i) the ROFO Space has not been leased within 180 days following
Landlord's Notice as to such ROFO Space, or (ii) Landlord proposed to lease the
ROFO Space to a third party at a net effective rental rate that is less than 95%

lease storage space in the lower level of the Project, subject to availability,
at the gross rental rate of $12.00 per square foot.

Leasehold Improvements:

          (a) Prior to commencing the Leasehold Improvements, Tenant shall
          submit to Landlord for Landlord's review and approval (i) the names
          and addresses of Tenant's contractors (and said contractors (and said
          contractor's subcontractors) and materialmen to be engaged by Tenant
          for the Leasehold Improvements (individually, a "TENANT

<PAGE>

          CONTRACTOR" and collectively, "TENANT'S CONTRACTORS"), and (ii)
          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. Landlord has the right to reasonably approve or disapprove
          all or any one or more of Tenant's Contractors.

          (b) Tenant, at its sole cost and expense (subject to the Allowance, as
          hereinafter defined), shall perform, or cause to be performed, the
          Leasehold Improvements in the Leased Premises in accordance with the
          Construction Documents. The Leasehold Improvements shall be
          constructed in a good and workmanlike fashion, in accordance with the
          requirements set forth herein and in compliance with all applicable
          laws, statutes, ordinances, codes, rules and regulations. Tenant shall
          commence the construction of the Leasehold Improvements promptly after
          completion of the preconstruction activities described in paragraph
          3.01(a) above and shall diligently proceed with all such construction.
          Tenant shall coordinate the construction of the Leasehold Improvements
          so as to avoid unreasonable interference with any other work being
          performed by or on behalf of Landlord and other tenants of the
          Building.

          (c) Tenant shall, at its own cost and expense, obtain all required
          building permits and occupancy permits. Tenant's failure to obtain
          such permits shall not cause a delay in the Lease Commencement Date or
          the obligation to pay Rent or any other obligations set forth in the
          Lease.

     3.02 If there are any changes in the Leasehold Improvements requested by,
or on behalf of, Tenant from the work as reflected in the Construction
Documents, each such change must receive the prior written approval of Landlord,
which approval shall not be unreasonably withheld or delayed, and Tenant shall
bear the cost of all such changes.

     3.03 Tenant acknowledges that Landlord's sole monetary obligation is to pay
the costs attributable to the construction of the Leasehold Improvements, up to
an aggregate maximum limit of $20.00 per square foot of Tenant's Square Footage
(the "ALLOWANCE"), and Tenant shall pay all other costs of the construction of
the Leasehold Improvements ("TENANT'S SHARE"). In addition, all costs
attributable to changes and variations from the Construction Documents
(including, without limitation, any fees and expenses of the consultants and any
increased costs of construction) shall be paid by Tenant. The Allowance shall be
paid out to Tenant from time to time during the course of construction of the
Leasehold Improvements, but not more often than once a month. Disbursements of
the requested amounts shall be made upon submission to Landlord of the following
documents:

          (a) a draw request from Tenant in a form acceptable to Landlord,
          together with copies of the invoices for which payment is being
          requested;

          (b) lien waivers (to the extent available under local law) and sworn
          statements from Tenant's Contractors, subcontractors, laborers and
          material suppliers pertaining to the Leasehold Improvements;

          (c) a certificate from Tenant's architect that all work (labor and
          materials) for which the draw request has been made has been completed
          and performed in a

<PAGE>
          good and workmanlike manner and substantially in accordance with the
          Construction Documents;

          (d) such evidence as Landlord may reasonably require certifying that
          any portion of the Leasehold Improvements requiring inspection by
          governmental authorities has been duly inspected and approved; and

          (e) such other evidence as Landlord may reasonably require in order to
          establish that the work for which payment is being requested has been
          satisfactorily completed and paid for or is to be paid for from the
          requested disbursement.

In addition, the final payment request shall also be accompanied by (1) final
lien waivers from Tenant's Contractor, subcontractors, laborers and material
suppliers, (2) as-built drawings of the Leased Premises; and (3) a certificate
from Tenant's architect that the Work has been substantially completed in
accordance with the Construction Documents.

     3.04 Tenant shall pay Landlord a supervisory fee in an amount equal to
three percent (3%) of the direct cost of the materials and labor for the Work
(and all change orders with respect thereto) to defray Landlord's administrative
and overhead expenses incurred to review the Plans and coordinate with Tenant's
project manager the staging and progress of the Work.

     3.05 Notwithstanding anything to the contrary contained herein, up to
$10.00 per square foot of Tenant's Square Footage of the Allowance may be
applied to the cost of the following: (i) permits and inspections, (ii)
architectural and engineering costs, (iii) Tenant's moving costs, (iv)
Landlord's supervisory fees, (v) the costs of consultants utilized by Tenant in
connection with the Leased Premises, (vi) furniture or furnishings to be
installed in the Leased Premises, (vii) telecommunications and cabling in the
Leased Premises, (viii) Tenant's signage at the Leased Premises, and (ix) Base
Rent due hereunder.

4.   Lease Commencement Date; Delays

     4.01 Tenant shall notify Landlord when Substantial Completion has been
achieved. In the event Tenant fails to complete the Leasehold Improvements on or
before the Lease Commencement Date, Tenant shall be responsible for Rent and all
other obligations set forth in the Lease from the Lease Commencement Date
regardless of the degree of completion of the Leasehold Improvements on such
date, and no such delay in completion of the Leasehold Improvements shall
relieve Tenant of any of its obligations under the Lease.

     4.02 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 Lease
Commencement Date or the payment of Rent and other obligations therein set
forth. All increases in the cost of the Work resulting from such change orders
shall (subject to the Allowance) be borne by Tenant.

5.   Insurance; Indemnity

     5.01 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 the Leased Premises, insurance in the

<PAGE>

          (a) Worker's Compensation Insurance with limits not less than those
          required by law.

          (b) Commercial General Liability Insurance (including Contractors'
          Protective Liability) in an amount not less than $1,000,000 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 $1,000,000, and with
          umbrella coverage with limits not less than $10,000,000.00. Such
          insurance shall provide for explosion and collapse, completed
          operations coverage and broad form blanket 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.

          (c) 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.

          (d) "All-risk" Builder's Risk Insurance upon the Leasehold
          Improvements 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 Leasehold Improvements 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 Leasehold Improvements 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 Leasehold Improvements. 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.

     5.02 All policies (except the Worker's Compensation policy) shall be
endorsed to include as additional insureds, Landlord (and the constituent
members of Landlord generally), the Managing Agent, 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 Worker's Compensation
policy) to be obtained by Tenant pursuant to this paragraph. The insurance
policy endorsements shall also provide that all additional insured parties shall
be given thirty (30) days' prior written notice of any reduction, cancellation
or non-renewal of coverage (except that ten (10) days' notice shall be
sufficient in the case of cancellation for non-payment of premium) and shall
provide that the insurance coverage afforded to the additional insured parties
thereunder shall be primary to any insurance carried independently by said
<PAGE>

additional insured parties. Additionally, where applicable, each policy shall
contain a cross-liability and severability of interest clause.

     5.03   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 property manager and
their respective members, beneficiaries, 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
construction of the Leasehold Improvements or the entry of Tenant or Tenant's
Contractors into the Building and the Leased Premises, including, without
limitation, mechanic's liens, the cost of any repairs to the Leased Premises or
Building necessitated by activities of Tenant or Tenant's Contractors, bodily
injury to persons or damage to the property of Tenant, its employees, agents,
invitees, licensees or others, except to the extent caused by Landlord's
negligence or willful misconduct. 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.

6.   Miscellaneous Provisions. Landlord and Tenant further agree as follows:

     6.01   Except as herein expressly set forth with respect to the Leasehold
Improvements, Landlord has no agreement with Tenant and has no obligation to do
any work with respect to the Leased Premises. Any other work in the Leased
Premises which may be permitted by Landlord pursuant to the terms and
conditions of the Lease shall be done at Tenant's sole cost and expense and in
accordance with the terms and conditions of the Lease. Notwithstanding the
foregoing, on or before the Lease Commencement Date, Landlord, at Landlord's
sole cost and expense, shall construct the common corridor outside the Leased
Premises as shown on the Preliminary Plan.

     6.02   This Schedule shall not be deemed applicable to: (a) any additional
space added to the original Leased Premises at any time, whether by the
exercise of any options under the Lease or otherwise, or (b) any portion of the
original Leased Premises or any additions thereto in the event of a renewal or
extension of the original Lease Term, whether by the exercise of any options
under the Lease or any amendment or supplement thereto. The construction of any
additions or improvements to the Leased Premises not contemplated by this
Schedule shall be effected pursuant to a separate work letter agreement or
other document, in the form then being used by Landlord and specifically
addressed to the allocation of costs relating to such construction.

     6.03   If Tenant fails to make any payment relating to the Leasehold
Improvements as required hereunder and such failure shall continue for fifteen
(15) days after written notice from Landlord, Landlord, at its option, may
complete the Leasehold Improvements pursuant to the Construction Documents and
continue to hold Tenant liable for the costs thereof and all other costs due to
Landlord. Tenant's failure to pay any amounts owed by Tenant hereunder when due
or Tenant's failure to perform its obligations hereunder shall also constitute
a default under the Lease and Landlord shall have all the rights and remedies
granted to Landlord under the Lease for nonpayment of any amounts owed
thereunder or failure by Tenant to perform its obligations thereunder.

     6.04   On or before the Lease Commencement Date, Landlord, at Landlord's
sole cost and expense, shall construct the common corridor outside the Leased
Premises as shown on
<PAGE>

corridor shall not be charged against the Allowance.
