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

         This Agreement, made this 18th day of October, 2001 by and between T&L
A Partnership of South Carolina, hereinafter referred to as Landlord, and
Advanced Biosensor, Inc., hereinafter referred to as Tenant.

                                   WITNESSETH

         That Landlord, for and in consideration of the rents, covenants and
agreements herein contained to be paid and agreed to be performed by Tenant,
does hereby warrant and lease to Tenant the following described property.

     PREMISES. All of that office space containing approximately 10,080 square
     feet as measured from the window surface of the outer building walls in the
     County of Richland, State of South Carolina, and hereinafter referred to as
     the "Leased Premises" located at No. 6 Woodcross Drive, Harbison Industrial
     Park, Columbia, SC 29212.

     TERM. The term of this Lease shall be for a period of three (3) years,
     commencing on the 1st day of November, 2001 and expiring on the last day of
     October, 2004.

     RENTAL. Tenant shall pay to Landlord promptly on the first day of each
     month in advance during the term of this Lease a monthly rental which shall
     be payable to T&L A Partnership (See Addendum "A"). In the event Tenant
     shall fail to pay any rental on the due date or within ten (10) days
     thereafter, late charges of six (6) percent of the monthly rental shall be
     added to the rental for each such late payment, and the same be treated as
     additional rent.

     NOTICES. Until otherwise notified in writing by Landlord, Tenant shall make
     payment of rental and give notices to Landlord at 1016 Calks Ferry Road,
     Lexington, SC 29072, attention of Gary L. Traywick, General Partner.
     Landlord shall give notices and other communications to Tenant by mailing
     same to:

             Advance Biosensor, Inc.
             No. 6 Woodcross Drive
             Columbia, SC  29212

     SECURITY DEPOSIT. The Security Deposit of $6,720.00 not on deposit with the
     Landlord will be retained as security during the term of this Lease for the
     faithful performance and observance of Tenant of the terms of this Lease.
     In the event Tenant defaults with respect to any of the terms of this Lease
     including, but not limited to, the payment of rent, Landlord may use the
     whole or any part of the deposit to the extent required, but Tenant shall
     remain liable for any additional amounts due. If Tenant shall comply fully
     with all of the terms of this Lease, the security deposit shall be returned
     to

<PAGE>

     Tenant upon the expiration of the lease term. In the event of the sale or
     lease of the property of which the leased premises are a part, Landlord
     shall have the right to transfer the unused security deposit to the new
     purchaser or lessee who shall be responsible to the Tenant for the security
     deposit and Landlord shall be released from all liability for its return.

     USE. The premises shall be used for the normal operating practices of
     Tenant's business, but shall not be used for any illegal purpose, nor in
     any way that would increase the rate of insurance or invalidate the
     insurance coverage on the premises, nor in any manner interfere with or
     infringe upon the rights of Landlord. Tenant shall at all times abide by
     the Rules and Regulations which are attached to and hereby expressly made a
     part of this Lease.

     1.   IMPROVEMENTS. Landlord agrees to allow Tenant to make changes to
          interior floor plan of building with prior notification in writing as
          to extent and type of modification. Tenant agrees to return building
          and interior to original configuration or negotiated monetary
          settlement for reconfiguration if deemed necessary by Landlord, prior
          to release of responsibilities of this Lease. All additions,
          alterations, and improvement allowed by Landlord shall be deemed to be
          the property of the Landlord and shall not be removed by Tenant
          without Landlord's consent. All additions, alterations, and
          improvements to grounds and building shall be done at Tenant's
          expense.

     2.   QUIET POSSESSION. Landlord warrants that is seized with good and
          sufficient title to the entire premises, and further covenants that if
          Tenant shall discharge the obligations herein set forth to be
          performed by Tenant, the Tenant shall have and enjoy the quiet and
          undisturbed possession of the leased premises without hindrance or
          interference from Landlord or any other person lawfully claiming by,
          through or under Landlord.

     3.   SERVICES. Tenant shall provide at his own expense a HVAC service
          contract for all maintenance and repair of heating/cooling units.
          Tenant is responsible for all maintenance and repair of the interior
          and exterior of the building and grounds, with the exception of the
          roof and structural damage which shall remain the Landlord's
          responsibility. (See Addendum "A").

     4.   PROPERTY TAXES, INSURANCE AND OPERATING EXPENSES. Landlord agrees to
          pay property taxes within fifteen (15) days or on before January 15 of
          each year of lease term. Tenant shall obtain property insurance in at
          least the same coverage as Landlord provided prior to lease, naming
          T&L as additional insured, and maintaining such coverage for the term
          of this Lease or extension.

     5.   DAMAGE TO PREMISES. If the leased premises are damaged or destroyed by
          fire or other casualty, Landlord shall begin repair or restoration of
          the leased premises within sixty (60) days after the date full
          insurance is paid to Landlord and if not begun within this time period
          the Tenant shall have the option of terminating this Lease; provided,
          however, that if the said damage shall occur

                                       3
<PAGE>

          within six (6) months of the expiration date of this Lease, Landlord
          shall have the right within fifteen (15) days to elect to terminate
          this Lease; and provided, further, that should the building in which
          the leased premises are located be damaged by fire or other casualty
          to such an extent that Landlord determines to discontinue the leasing
          of office space in the building, then Landlord shall have the right
          within fifteen (15) days to elect to terminate this Lease. If the
          damage or destruction to the leased premises was caused without fault
          of Tenant, the rental required by this Lease shall abate
          proportionately to the extent that the premises are untenable by
          Tenant. In the event of the termination of this Lease, the term hereby
          granted shall cease, rent shall be apportioned and paid to the date of
          such damage, and Tenant shall not be liable for any further rent after
          such termination. All furniture, trade fixtures, files and other
          property of Tenant located at the leased premises shall be at the sole
          risk of Tenant, and Landlord shall not in any way be liable for damage
          to such property of Tenant.

          Except as may be otherwise be provided in this Lease, Landlord and
          Tenant mutually agree that in the event of loss or damage to the
          entire premises, the leased premises and/or any contents, each party
          shall look first to any insurance in its favor before making any claim
          against the other party, and to the extent possible without additional
          cost, each part shall obtain for each policy of such insurance
          provisions permitting waiver of any claim against the other party for
          loss or damage within the scope of its insurance, and each party to
          such extent permitted for itself and its insurers waives all such
          insured claims against the other party.

     6.   MAINTENANCE AND REPAIRS. Tenant shall keep the leased premises in good
          care during the term of this Lease and shall surrender same with keys
          thereto at the end of the lease term in good and clean condition,
          reasonable wear and tear and damage by fire or other casualty
          excepted.

     7.   RIGHT OF ENTRY. Landlord shall have the right to enter the leased
          premises at reasonable hours to examine the same, or to install
          plumbing, electrical, telephone or mechanical lines, or to make such
          repairs, additions or alterations as it shall deem necessary, or to
          exhibit the same to prospective purchasers, or to exhibit the premises
          beginning ninety (90) days prior to the expiration of the lease term
          to prospectives.

     8.   ASSIGNMENTS. Landlord agrees that Tenant can assign or sublet in whole
          or in part any portion of the premises. Any assignee or sublessee must
          agree to abide by all of the terms of this Lease, and Tenant shall not
          be relieved from any of its obligations assumed under this Lease.

     9.   SUBORDINATION. Tenant agrees that its rights under this Lease shall at
          all times by subordinated to the lien or any and all mortgages, ground
          or underlying leases, or to the lien resulting from any other method
          of financing or financing now or hereafter in force against the land
          and/or building of which the leased premises are a part provided that
          the mortgagee or other lienholder shall agree

                                       4
<PAGE>

          that so long as the Tenant is not in default under the terms hereof,
          Tenant's rights under said Lease shall not be disturbed and that if on
          account of foreclosure or sale pursuant to the terms of any such
          security instruction the new owner will attorn to the Tenant and
          complete the Landlord's obligations under this Lease provided the
          Tenant is not then and does not thereafter default under the terms
          hereof. Tenant agrees to execute any documents which may be required
          to effectuate the subordination.

     10.  CONDEMNATION. If any time during the term of this Lease the entire
          property or any such substantial part as may render it unsuitable for
          its current use is taken for a public or quasi-public use under
          statute or any right of eminent domain, then in such event, when title
          vests in the condemning authority, the term of this Lease shall
          immediately cease and the Lease shall terminate. Tenant shall have no
          claim against the award made to Landlord for such taking or against
          Landlord for the value of any unexpected term of this Lease.

     11.  HOLD HARMLESS. Tenant agrees to indemnify and save Landlord harmless
          against any and all claims, demands, damages, cost and expenses,
          including reasonable attorney's fees for the defense thereof existing
          from the conduct of the management of the business operated by Tenant
          to the leased premises or from any breach or default on the part of
          Tenant of any covenant or provision of this Lease or from any act of
          Tenant, its employees or agents, and Tenant agrees to defend any such
          action or proceeding by counsel reasonably satisfactory to Landlord.
          Landlord shall not be responsible for the carelessness or negligence
          of other tenants. Landlord agrees to hold Tenant harmless for injury
          to any person by virtue of any structural or other defect in the
          building occupied by Tenant.

     12.  DEFAULT. If Tenant shall fail to pay the base rent or any additional
          rent as provided within this Lease or shall fail to perform any of the
          covenants and agreements required under this Lease, or if Tenant shall
          vacate or abandon the leased premises prior to the expiration of the
          term of this Lease or suffer the lease to be taken under any writ of
          execution, or if a petition to bankruptcy, insolvency or for
          reorganization is filed by or against Tenant, or if Tenant shall make
          an assignment for the benefit of creditors, then in any of such
          events, Landlord may deem Tenant to be in default under this Lease and
          if such default is not remedied to Landlord's satisfaction within
          fifteen (15) days after written notice of such default is delivered to
          Tenant, Landlord may at its option terminate this Lease and all rents
          then due and which would become due during the remainder of the term,
          together with such special damages that Landlord may suffer, shall
          immediately become due and payable. Landlord shall also have the right
          of re-entry and repossession of the leased premises and may expel
          Tenant and remove all property therefrom with the right to sell same
          and apply the proceeds against any amounts due under this Lease.
          Landlord may at its option without terminating this Lease have full
          right of entry and may make such reasonable alterations and repairs as
          may be needed in order to relet the leased premises or any part
          thereof upon such rental, terms and conditions as it deems advisable,
          and Tenant shall remain liable to Landlord for any deficiency between
          the rent reserved hereunder

                                       5
<PAGE>

          for the remainder of the term and the rental, if any, obtained by
          Landlord in reletting. The failure of Landlord to relet the premises
          shall not in any way release or reduce Tenant's liability.

     13.  ATTORNEY'S FEES. If Tenant defaults in the performance of any of the
          covenants of this Lease and by reason thereof Landlord employs the
          services of an attorney to enforce performance by Tenant, to evict
          Tenant, to collect monies due by Tenant, or to perform any service
          based upon said default, then the Tenant shall pay a reasonable
          attorney's fee and all reasonable expenses and costs incurred by
          Landlord pertaining thereto.

     14.  NON-WAIVER. The failure of Landlord or Tenant to insist upon strict
          performance of any of the terms, conditions and covenants herein shall
          not be deemed to be a waiver of any rights or remedies that Landlord
          or Tenant may have, and shall not be deemed a waiver of any subsequent
          breach or default in the term, conditions and covenants herein
          contained except as may expressly be waived in writing.

     15.  HOLDING OVER. In the event Tenant shall continue to remain in and
          occupy the premises with the consent of Landlord after the expiration
          of the term of this Lease, such holding over shall not be deemed in
          any way to be a renewal or extension of the term of this Lease, but
          shall constitute a tenancy from month to month only, subject to all
          the covenants and conditions of this Lease, other than those relating
          to the term hereof, for which tenancy Tenant agrees to pay Landlord a
          mutually agreed upon month-by-month rental.

     16.  NON-EASEMENT. It is understood and agreed that this Lease does not
          grant any rights to light and air over property adjoining the land on
          which the leased premises are situated.

     17.  GENERAL.

          A.   This Agreement shall be governed by and construed according to
               the laws of the State of South Carolina.

          B.   The captions and titles appearing within this Lease are for
               reference only and shall not be considered a part of this Lease
               or in any way to modify, amend or affect the provisions thereof.

          C.   The proper grammatical changes shall be understood and shall
               apply where necessary to designate the plural rather than the
               singular and the masculine or feminine gender.

          D.   This Lease may be recorded by either party. The cost of South
               Carolina Documentary Stamp Taxes due shall be paid by the Tenant.

          E.   This Lease dated October 18, 2001 sets forth all of the
               covenants, premises, agreements, conditions and understandings
               between Landlord

                                       6
<PAGE>

               and Tenant, concerning the leased premises. No subsequent
               alteration or amendment shall be binding upon Landlord or Tenant
               unless reduced to writing and signed by each party.

          F.   Landlord does not in any way or for any purpose become a partner
               of Tenant in the conduct of its business, or otherwise, or a
               joint venturer or a member of a joint enterprise with Tenant.

          G.   The conditions, covenants and agreements contained in this Lease
               shall be binding upon and inure to the benefit of the parties
               hereto and their respective successors, heirs, executors,
               administrators and assigns. No rights, however, shall inure to
               the benefit of any assignee of Tenant unless the assignment to
               such assignee has been made in accordance with the provisions set
               out in this Lease.

interest at the rate set forth in Sections 25M and 26F hereof, from the date due
until paid.

     B. Commencing on the first day of the thirteenth (13th) full calendar month
of the Term and on the first day of each succeeding twelve (12) month period (or
portion thereof) thereafter during the remainder of the Term of this Lease the
Annual Base Rent payable pursuant to the preceding Section 3A (as previously
adjusted pursuant to this Section 3B) shall be increased annually by an amount
equal to

<PAGE>

three percent (3%) of the annual Base Rent payable for the then current calendar
year, payable in equal monthly installments. Each such adjustment pursuant to
this Section 3B shall be added to the prior year's Base Rent as previously
adjusted pursuant to this Section 3B. All amounts due hereunder shall be deemed
to be Additional Base Rent and shall be paid at the same time and in the same
manner as Initial Monthly Base Rent pursuant to Section 3A of Lease. The Initial
Monthly Base Rent and the Additional Base Rent are collectively sometimes herein
referred to as "Base Rent."

     4. BASE RENT ADJUSTMENT. In addition to the Base Rent, Tenant shall pay, on
a monthly basis, without set off or deduction the Rent Adjustment described in
this Section 4. Until such time as Tenant receives the first Adjustment
Statement as described in Paragraph C of this Section 4, Tenant shall, on a
monthly basis, make the Initial Monthly Rent Adjustment Deposit specified in
Section 1.

     A. For the purposes of this Lease:

          (i) The term "Calendar Year" shall mean each calendar year or any
     portion thereof during the Term.

          (ii) The term "Expenses" shall mean and include all expenses paid or
     incurred by Landlord or its beneficiaries for managing, owning,
     maintaining, operating, insuring, replacing and repairing the Building, the
     land underlying the Building (which is described on Exhibit D attached
     hereto) and appurtenances and personal property used in conjunction
     therewith (hereinafter collectively referred to as the "Project") during
     each Calendar Year, or portion thereof, during the Term. Expenses shall not
     include costs of alterations of the Premises of tenants of the Building,
     depreciation charges, interest and principal payments on mortgages, ground
     rental payments, real estate brokerage and leasing commissions. If the
     Building is not fully occupied during all or a portion of any year, then
     Landlord may elect to make an appropriate adjustment of the Expenses for
     such year employing sound accounting and management principles, to
     determine the amount of Expenses that would have been paid or incurred by
     Landlord had the Building been fully occupied and the amount so determined
     shall be the amount of Expenses attributable to such year. If any Project
     expense, though paid in one year, relates to more than one calendar year,
     at the option of Landlord, such expense may be proportionately allocated
     among such related calendar years.

          (iii) The term "Lease Year" shall mean each twelve (12) month period
     commencing on the day on which the Term begins and on each anniversary of
     such date.

          (iv) The term "Rent Adjustment Deposit" shall mean an amount equal to
     Landlord's estimate of Rent Adjustment due for any Calendar Year.

          (v) The term "Taxes" shall mean real estate taxes, assessments, sewer
     rents, rates and charges, transit taxes, taxes based upon the receipt of
     rent and any other federal, state or local governmental charge, general,
     special, ordinary or extraordinary (but not including general income or
     franchise taxes or any other taxes imposed upon or measured by income or
     profits, unless the same shall be imposed in lieu of Taxes as herein
     defined or unless same shall be specifically imposed upon income derived
     from rents), which may now or hereafter be levied or assessed against the
     Project or any portion thereof which are payable in any Calendar Year
     during the Term. In case of special taxes or assessments which may be
     payable in installments, only the amount of each installment and interest
     paid thereon paid during a Calendar Year shall be included in Taxes for
     that year. Taxes shall also include any personal property taxes
     (attributable to the year in which paid) imposed upon the furniture,
     fixtures, machinery, equipment, apparatus, systems and appurtenances used
     in connection with the operation of the Building. In the event

                                      -2-
<PAGE>

     the Project is not assessed as fully improved for any year, then Taxes
     shall be adjusted to the Taxes which would have been payable in such
     Calendar Year if the assessment had been made on a fully improved basis,
     based on Landlord's adjustment of the "Taxes" for such year, employing
     sound management principles. Taxes also include Landlord's reasonable costs
     and expenses (including reasonable attorney's fees) in contesting or
     attempting to reduce any taxes. Taxes shall be reduced by any recovery or
     refund received of taxes previously paid by Landlord, provided such refund
     relates to taxes paid during the term of this Lease. Notwithstanding
     anything set forth above to the contrary, if at any time the method of
     taxation then prevailing shall be altered so that any new or additional
     tax, assessment, levy, imposition or charge or any part thereof shall be
     imposed upon Landlord in place or partly in place of any Taxes or
     contemplated increase therein, or in addition to Taxes, and shall be
     measured by or be based in whole or in part upon the Project, the rents or
     other income therefrom or any leases of any part thereof, then all such new
     taxes, assessments, levies, impositions or charges or past thereof, to the
     extent that they are so measured or based, shall be included in Taxes.

          (vi) The term "Tenant's Proportion" shall be 1.0%.

     B. Tenant shall pay as Rent Adjustment for each Calendar Year of the Term,
the following:

          (i) Tenant's Proportion of Expenses for such year (prorated for any
     partial Calendar Year during the Term).

          (ii) Tenant's Proportion of Taxes for such year. The amount of Taxes
     attributable to a year shall be the amount payable during any such Calendar
     Year, even though the assessment for such Taxes may be for a different
     Calendar Year.

     C. As soon as reasonably feasible after the expiration of each Calendar
Year, Landlord will furnish Tenant a statement ("Adjustment Statement") showing
the following:

          (i) Expenses and Taxes attributable to the Calendar Year last ended;

          (ii) The amount of Rent Adjustment due Landlord for the Calendar Year
     last ended, less credits for Rent Adjustment Deposits paid, if any; and

          (iii) The Rent Adjustment Deposit due in the current Calendar Year.

     D. Within thirty (30) days after Tenant's receipt of each Adjustment
Statement, Tenant shall pay to Landlord:

          (i) The amount of Rent Adjustment shown on said statement to be due
     Landlord for the Calendar Year last ended; plus

          (ii) The amount, which when added to the Rent Adjustment Deposit
     theretofore paid in the current Calendar Year, would provide that Landlord
     has then received such portion of the Rent Adjustment Deposit as would have
     theretofore been paid to Landlord had Tenant paid one twelfth (1/12) of the
     Rent Adjustment Deposit, for the current Calendar Year, to Landlord monthly
     on the first day of each month of such Calendar Year.

     Commencing on the first day of the first month after Tenant's receipt of
each Adjustment Statement, and on the first day of each month thereafter until
Tenant receives a more current Adjustment Statement, Tenant shall pay to
Landlord one-twelfth (1/12) of the annual Rent Adjustment Deposit shown

                                      -3-
<PAGE>

on said statement. During the last complete Calendar Year, Landlord may include
in the Rent Adjustment Deposit its estimate of the Rent Adjustment which may not
be finally determined until after the expiration of the Term. Tenant's
obligation to pay the Rent Adjustment shall survive the expiration of the Term.

     E. Tenant's monthly payments of the Rent Adjustment Deposit for each
Calendar Year shall be credited against the Rent Adjustment for such Calendar
Year. Rent Adjustment Deposit may be co-mingled with other funds of Landlord and
no interest shall be paid to Tenant thereon. If the Rent Adjustment Deposit paid
by Tenant for any Calendar Year exceeds the Rent Adjustment for such Calendar
Year, then Landlord shall give a credit to Tenant in an amount equal to such
excess against the Rent Adjustment due for the next succeeding Calendar Year,
except that if any such excess relates to the last Calendar Year of the Term,
then Landlord shall refund such excess to Tenant, provided that all of the
following have first occurred:

          (i) The Term has expired or otherwise been terminated;

          (ii) Tenant has vacated the Premises and removed all of its property
     and improvements therefrom in accordance with this Lease;.

          (iii) Tenant has surrendered the Premises to Landlord in accordance
     with this Lease; and

          (iv) Tenant has paid all Base Rent and eat Adjustment due under this
     Lease and has fully performed and observed each and every covenant and
     condition of this Lease required to be performed or observed by Tenant and
     has no other monetary obligations outstanding to Landlord.

     F. Tenant or its representative shall have the right to examine Landlord's
books and records with respect to the items in the Adjustment Statement during
normal business hours at any time within ten (10) days following the furnishing
by Landlord to Tenant of such Adjustment Statement. Unless Tenant shall take
written exception to any item within thirty (30) days after the furnishing of
the foregoing statement such statement shall be considered as final and accepted
by Tenant. Any amount due to Landlord as shown on any such statement, whether or
not written exception is taken thereto, shall be paid by Tenant within thirty
(30) days after Landlord Shall have submitted the statement, without prejudice
to any such written exception.

     G. If the Commencement Date is on any day other than the first day of
January, or if the Termination Date is on any day other than the last day of
December, any Rent Adjustment due Landlord shall be prorated accordingly.

     5. SERVICES.

     A. Landlord shall, so long as Tenant is not in default under any covenant
or condition herein contained, furnish:

          (i) Heating and air cooling when necessary to provide a temperature

     When heat generating machines or equipment are used by Tenant in the
     Premises, which affect the temperature otherwise maintained by the
     air-cooling system, Landlord reserves the right to install supplementary
     air-conditioning units in the Premises and the expense of furnishing such
     units and installation thereof shall be paid by Tenant. The expense
     resulting from the operation and maintenance of the supplementary air
     conditioning system shall be paid by Tenant to Landlord as Additional Rent
     at rates fixed by Landlord.

                                      -4-

     and toilet purposes drawn through fixtures installed by Landlord, or by
     Tenant with Landlord's prior written consent, and warm water for lavatory
     purposes from the regular supply of the Building. Tenant shall pay Landlord
     at rates fixed by Landlord for, water furnished for any other purposes, and
     Landlord may install a water meter at Tenants sole cost to measure such
     usage. Tenant shall not waste or permit the waste of water. In the event
     Tenant shall fail to make prompt payment to Landlord for water furnished by
     Landlord, Landlord, upon ten (10) days notice, may discontinue furnishing
     such service and no such discontinuance shall be deemed an eviction or
     disturbance of Tenant's use of the Premises or render Landlord liable for
     damage or relieve Tenant from any obligation under this Lease.

          (iii) Customary janitor service and cleaning in and about the Premises

     satisfactory to Landlord.

          (iv) Building access and passenger elevator service in common with
     Landlord and other tenants on a twenty-four hour, seven day a week, basis,
     and daily freight elevator service in common with Landlord and other
     tenants at reasonable hours to be determined by Landlord, Saturdays,
     Sundays and holidays excepted. Operatorless automatic elevator service
     shall be deemed "elevator service" within the meaning of this paragraph.
     Landlord shall provide Tenant at commencement of Lease with one electronic
     card key for each 250 square feet of Premises at no charge, if Tenant shall
     require additional or replacement card keys, Landlord shall provide such
     additional or replacement card keys at a cost of $10 per card key. Tenant
     shall, at the expiration of the Lease, or upon vacating the Premises return
     all keys to Landlord or pay $10 per card key for each card key not
     returned.

     B. All electricity, telecommunication, signal, and other similar services
used in the Premises shall be supplied by the utility company serving the
Building. Tenant shall pay as additional rent, on the date for payment of Base
Rent, the Initial Electric Charge as set forth in Section 1. Such Initial
Electric Charge shall be adjusted annually to reflect changes in the cost of
electricity provided to the Building. Landlord shall notify Tenant of any change
in the Electric Charge and Tenant shall pay, as additional rent commencing on
the first day of the first month after such notice, the adjusted Electric
Charge. If Tenant operates extensive computer or other energy intensive
machinery or equipment, or if Tenant requires use of electricity for other than
normal and usual lighting and incidental office use after 6:00 P.M. and before
8:00 A.M. on weekdays and after 1:00 P.M. on Saturdays, Landlord may install, at
Tenants expense, separate meters to measure such excess usage and the costs
thereof shall be billed directly to Tenant. Landlord shall not in any way be
liable or responsible to Tenant for any loss or damage or expense which Tenant
may sustain or incur if either the quantity or character of such service is
changed or is no longer available or suitable for Tenants requirements. If such
service be discontinued, such discontinuance shall not in any way affect this
Lease or the liability of Tenant hereunder or cause a diminution of Base Rent or
Rent Adjustment and the same shall not be deemed to be a lessening or diminution
of services within the meaning of any law, rule or regulation now or hereafter
enacted, promulgated or issued. Tenant shall receive such service directly from
the utility company and Landlord hereby permits its wires and conduits, to the
extent available, suitable and safely capable, to be used for such purposes.

     C. Landlord does not warrant that any of the services above-mentioned will
be free from interruption caused by war, insurrection, civil commotions, riots,
acts of God or the enemy, governmental action, repairs, renewals, improvements,
alterations, strikes, lockouts, picketing, whether legal or illegal, accidents,
the inability of Landlord to obtain fuel, energy or supplies or any other cause
or causes beyond

                                      -5-
<PAGE>

the reasonable control of Landlord. No such interruption of service shall be
deemed an eviction (or a constructive eviction) or disturbance of Tenant's use
and possession of the Premises or any part thereof, 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. Tenant hereby waives and
releases all claims against Landlord for damages from interruption or stoppage
of service. Tenant agrees to cooperate fully with Landlord, at all times, in
abiding by all regulations and requirements which Landlord may prescribe for the
proper functioning and protection of all utilities and services reasonably
necessary for the operation of the Project and the Building.

     6. CONDITION OF PREMISES. Tenant's taking possession of the Premises shall
be deemed to be Tenant's acceptance of the Premises in the order and condition
as then exists, except for a punch list of items to be completed or repaired,
signed by Landlord and Tenant within twenty (20) days of such possession. No
promise of Landlord to alter, remodel, decorate, clean or improve the Premises
or the Building and no representation respecting the condition of the Premises
or the Building have been made by Landlord to Tenant, except as contained
herein.

     7. INABILITY TO DELIVER POSSESSION. If Landlord shall be unable to give
possession of the Premises on the scheduled Commencement Date for any reason the
rent reserved and covenanted to be paid herein and the Commencement Date shall
not be deemed to have occurred until the Premises are available for occupancy by
Tenant. No such failure to give possession on the scheduled Commencement Date
shall subject Landlord to any liability for failure to give possession nor shall
same affect the validity of this Lease or the obligation of Tenant hereunder,
but the Lease shaft be amended, at the option of Landlord, so that the Term
shall be extended by the period of time possession is delayed. If the Premises
are ready for occupancy prior to the Commencement Date and Tenant occupies the
Premises prior to said date, Tenant shall pay proportionate Base Rent and Rent
Adjustments. The Premises shall not be deemed to be unready for Tenant's
occupancy or not substantially complete if only minor or insubstantial details
of construction, decoration or mechanical adjustments remain to be done in the
Premises or any part thereof, or if the delay in the availability of the
Premises for occupancy shall be due to special work changes, alterations or
additions required or made by Tenant in the layout or finish of the Premises or
any part thereof or shall be caused in whole or in part by Tenant through the
delay of Tenant in submitting plans, supplying information, approving plans,
specifications or estimates, giving authorizations, or shall be otherwise caused
in whole or in part by delay and/or default on the part of Tenant. In the event
of any dispute as to whether the Premises are ready for Tenant's occupancy, the
decision of Landlord's architect shall be final and binding on Landlord and
Tenant.

     8. CARE AND MAINTENANCE. Subject to the provisions of Sections 13 and 14
hereof, Tenant shall, at Tenant's own expense, keep the Premises in good order,
condition and repair and shall pay for the repair of any damages caused by
Tenant, its agents, employees or invitees. Tenant shall promptly arrange with
Landlord, at Tenant's sole expense, for the repair of all damage to the Premises
and the replacement or repair of all damaged or broken glass (including signs
thereon), fixtures and appurtenances (including hardware, heating, cooling,
ventilating electrical, plumbing and other mechanical facilities in the
Premises), with materials equal in qualify and class to the original materials
damaged or broken, within a reasonable period of time specified by Landlord. All
repairs and replacements are to be made under the supervision and with the prior
written approval of Landlord, using contractors or persons acceptable to
Landlord. If Tenant does not promptly make such arrangements, Landlord may, but
need not, make such repairs and replacements and one hundred twenty (120%)
percent of Landlord's cost for such repairs and replacements shall be deemed
additional rent reserved under this Lease which is due and payable forthwith.
Tenant shall pay Landlord or the managing agent of the Building, as Landlord may
direct, a for supervision and coordination of all work performed by Tenant as
well as all costs for overtime and for any other expense incurred in the event
repairs, alterations, decorating or other work in the Premises are not made
during ordinary business hours at Tenant's request.

                                      -6-
<PAGE>

     9. ALTERATIONS. Tenant shall not do any painting or decorating, or erect
any partitions, make any alterations in or additions to the Premises or do any
nailing, boring or screwing into the ceilings, walls or doors, without
Landlord's prior written consent in each and every instance. Unless otherwise
agreed by Landlord and Tenant in writing, all such work shall be performed
either by or under the direction of Landlord, but at the sole cost of Tenant.
Landlord's decision to refuse such consent shall be conclusive. If Landlord
consents to such alterations or additions, before commencement of the work or
delivery of any materials into the Premises or into the Building, Tenant shall
furnish Landlord for approval: (A) Plans and specifications; (B) Names and
addresses of contractors; (C) Copies of contracts; (D) Necessary permits; and
(E) Indemnification and insurance in form and amount satisfactory to Landlord
from all contractors performing labor or furnishing materials, insuring against
any and all claims, costs, damages, liabilities and expenses which may arise in
connection with the alterations or additions.

     Landlord may withhold approval of any alteration or additions if the plans
and specifications therefor are not acceptable to Landlord or Landlord's
architect or engineer (if any). In connection with any request for approval of
any alterations or additions by Tenant, Landlord may retain the services of an
outside architect and/or engineer and the reasonable fees of such architect
and/or engineer shall be reimbursed to Landlord by Tenant. Landlord's approval
of any plans or specifications shall not be construed to be an agreement or
representation on Landlord's part as to the adequacy or suitability of Tenant's
alterations or additions.

     In the event Landlord permits the alterations or additions to be completed
by Tenant's contractor, Landlord reserves the right to require that Tenant shall
terminate its contract with any such contractor in the event said contractor
shall be engaged in a labor dispute which disrupts said contractor work.
Landlord shall also have the right to order any contractor of Tenant who
violates any of Landlord's requirements or standards of work to cease work and
to remove himself, his equipment and his employees from the Building. Landlord
or the managing agent of the Building shall be entitled to charge a fee for
supervision and coordination of all such alterations. Tenant agrees that its
contractors shall not conduct their work in such a manner so as to interfere
with or cause any interruption of either (A) Landlord's construction; (B)
another tenant's occupancy or construction; or (C) other phases of Landlord's
operation of the Building.

     Tenant hereby agrees to indemnify and hold Landlord, its beneficiaries,
partners and their respective agents and employees harmless from any and all
liabilities of every kind and description which may arise out of or be connected
in any way with said alterations or additions. Any mechanic's lien filed against
the Premises, or the Project, for work claimed to have been furnished to Tenant
shall be discharged of record or bonded against by Tenant within ten (10) days
thereafter, at Tenant's expense. Upon completing any alterations or additions,
Tenant shall furnish Landlord with contractors' affidavits and full and final
waivers of lien and receipted bills covering all labor and materials expended
and used. All alterations and additions shall comply with all insurance
requirements and with all ordinances and regulations of any pertinent
governmental authority. All alterations and additions shall be constructed in a
good and workmanlike manner and only good grades of materials shall be used.

     All additions, decorations, fixtures, hardware, non-trade fixtures and all
improvements, temporary or permanent, in or upon the Premises, whether placed
there by Tenant or by Landlord, shall, unless Landlord requests their removal,
become Landlord's property and shall remain upon the Premises at the termination
of this Lease, by lapse of time or otherwise, without compensation or allowance
or credit to Tenant. Landlord may, at its sole option, request Tenant, at
Tenant's sole cost, to remove same at the termination of the Term, and if, upon
Landlord's request, Tenant does not remove said additions, decorations,
fixtures, hardware, non-trade fixtures and improvements, Landlord may remove the
same, and Tenant shall pay the cost of such removal to Landlord upon demand.

                                      -7-
<PAGE>

     10. ACCESS TO PREMISES. Tenant shall permit Landlord, its agents and
designees, to erect, use and maintain pipes, ducts, wiring and conduits in and
through the Premises and to have free access to the Premises and any part
thereof in the event of an emergency. Landlord or Landlord's agents shall also
have the right to enter upon the Premises, to inspect the same, to perform
janitorial and cleaning services, and to make such decorations, repairs,
alterations, improvements or additions to the Premises or the Project as
Landlord may deem necessary or desirable, and Landlord shall be allowed to take
all material into and upon said Premises that may be required thereof without
the same constituting an eviction of Tenant in whole or in part, and the rent
reserved shall in no way abate (except as provided in Sections 13 or 14 hereof)
while said decorations, repairs, alterations, improvements, or additions are
being made, by reason of loss or interruption of business of Tenant, or
otherwise. If Tenant shall not be personally present to open and permit an entry
into said Premises, at any time, when for any reason an entry therein shall be
necessary or permissible, Landlord or Landlord's agents may enter the same by a
master key, or may forcibly enter the same, without rendering Landlord or such
agents liable therefor (if during such entry Landlord or Landlord's agents shall
accord reasonable care to Tenant's property), and without in any manner
affecting the obligations and covenants of this Lease. Nothing contained in this
Section 10, however, shall be deemed or construed to impose upon Landlord any
obligations, responsibility or liability whatsoever for the care, supervision or
repair of the Building or any part thereof, in the exercise of any rights herein
provided. Landlord shall also have the right at any time without the same
constituting an actual or constructive eviction and without incurring any
liability to Tenant therefor, to change the Arrangement and/or location of
entrances or passageways, doors and doorways, and corridors, elevators, stairs,
toilets or public parts of the Building, and to close entrances, doors,
corridors, elevators or other facilities. Landlord shall not be liable to Tenant
for any expense, injury, loss or damage resulting from work done in or upon, or
the use of, any adjacent or nearby building, land, street or alley.

     11. INSURANCE. Tenant shall carry insurance during the entire Term hereof
insuring Tenant, and insuring, as additional named insureds, Landlord, any
beneficiary of Landlord, the managing agent for the Project and their respective
agents, partners and employees, and any mortgagee of Landlord, as their
interests may appear, with terms and coverage reasonably satisfactory to
Landlord and in companies licensed in the State of Illinois and satisfactory to
Landlord, and with such increases in limits as Landlord may from time to time
request, but initially Tenant shall maintain the following coverages in the
following amounts:

     A. Comprehensive public liability insurance, including the broad or
extended liability endorsement, during the entire term hereof with terms and in
companies satisfactory to Landlord to afford protection to the limits of not
less than $ 2,000,000 for combined single limit personal injury and property
damage liability per occurrence. $2,000,000 aggregate limit can be contained in
either a Primary General Liability Policy, or a $1,000,000 limit in a Primary
General Liability policy with a $1,000,000 Umbrella Policy.

     B. Insurance against fire, sprinkler damage, vandalism, and the extended
coverage perils for the full insurable value of all additions, improvements and
alterations to the Premises, and of all office furniture, trade fixtures, office
equipment, merchandise and all other items of Tenant's property on the Premises,
and business interruption insurance.

     C. Tenant shall, prior to the commencement of the Term, and during the
Term, thirty (30) days prior to the expiration of the policies of insurance,
furnish to Landlord certificates evidencing such coverage, which certificates
shall state that such insurance coverage may not be changed or canceled without
at least thirty (30) days' prior written notice to Landlord and Tenant.

     12. SUBROGATION. Landlord and Tenant agree to have all fire and extended
coverage and material damage insurance which may be carried by either of them
endorsed with a clause providing that

                                      -8-
<PAGE>

any release from liability of or waiver of claim for recovery from the other
party or any of the parties named in Section 11 above entered into in writing by
the insured thereunder prior to any loss or damage shall not affect the validity
of said policy or the right of the insured to recover thereunder, and providing
further that the insurer waives all rights of subrogation which such insurer
might have against the other party or any of the parties named in Section 11
above. Without limiting any release or waiver of liability or recovery contained
in any other Section of this Lease but rather in confirmation and furtherance
thereof, Landlord and any beneficiaries of Landlord waive all claims for
recovery from Tenant, and Tenant waives all claims for recovery from Landlord,
any beneficiaries of Landlord and the managing agent for the Project and their
respective agents, partners and employees, for any loss or damage to any of its
property insured under valid and collectible insurance policies to the extent of
any recovery collectible under such insurance policies.

     Notwithstanding the foregoing or anything contained in this Lease to the
contrary, any release or any waiver of claims shall not be operative, nor shall
the foregoing endorsement be required, in any case where the effect of such
release or waiver is to invalidate insurance coverage or invalidate the right of
the insured to recover thereunder or increase the cost thereof (provided that in
the case of increased cost the other party shall have the right, within ten (10)
days following written notice, to pay such increased cost, thereby keeping such
release or waiver in full force and effect).

     13. UNTENANTABILITY. If all or substantially all of the Premises, or in
excess of thirty (30%) percent of the Building, are made untenantable by fire or
other casualty, Landlord may, at its option, elect:

     A. To terminate this Lease as of the date of the fire or casualty by notice
to Tenant within sixty (60) days after that date; or

     B. Proceed with all due diligence to repair, restore or rehabilitate the
Building or the Premises (excluding leasehold improvements installed or paid for
by Tenant) at Landlord's expense, in which latter event this Lease shall not
terminate.

     In the event the Lease is not terminated pursuant to these provisions, rent
shall abate only with respect to the portion of the Premises rendered
untenantable on a per diem basis during the period of untenantability. In the
event of the termination of this Lease pursuant to this section, rent shall be
apportioned on a per diem basis and paid to the date of the fire or other
casualty. If less than thirty (30%) percent of the Building or less than all or
substantially all of the Premises are made untenantable as aforesaid during the
last year of the Term hereof, Landlord shall have the right to terminate this
Lease as of the date of the fire or other casualty by giving written notice
thereof to Tenant within sixty (60) days after the date of fire or other
casualty, in which event the rent shall be apportioned on per diem basis and
paid to the date of such fire or other casualty.

     14. EMINENT DOMAIN.

     A. If a portion of the Building, or the Premises, shall be lawfully taken
or condemned for any public or quasi-public use or purpose, or conveyed under
threat of such condemnation, and as a result thereof, the Premises cannot be
used for the same purpose and with the same utility as before such taking or
conveyance, the terms of this Lease shall end upon, and not before, the date of
the taking of possession by the condemning authority, and without apportionment
of the award. In such event, Tenant hereby assigns to Landlord, Tenant's
interest in such award, if any. Current rent shall be apportioned as of the date
of such termination. If any part of the Building shall be so taken or so
condemned, or, if the grade of any street or alley adjacent to the Building is
changed by any government authority and such taking or change of grade makes it
necessary or desirable to demolish, substantially remodel, or restore the

                                      -9-
<PAGE>

Building, Landlord shall have the right to cancel this Lease upon not less than
ninety (90) days' prior notice to Tenant.

     B. If a portion of the Premises shall be lawfully taken or condemned or
conveyed under threat of condemnation but thereafter the Premises can be used by
Tenant for the same purpose and with substantially the same utility, this Lease
shall not be terminated and Landlord shall repair the Premises, Building, and/or
common area (to the extent applicable), and the Lease shall be amended, if
applicable, to reduce Tenant's Proportion and Base Rent in the proportion of the
amount of the Premises taken. No money or other consideration shall be payable
by Landlord to Tenant for any right of cancellation or temporary taking and
Tenant shall have no right to share in any condemnation award or in any judgment
for damage caused by a change of grade.

     15. [Intentionally omitted]

     16. ASSIGNMENT/SUBLETTING.

     A. Tenant shall not, without Landlord's prior written consent, which in
each instance, may be withheld at the reasonable discretion of Landlord: (i)
assign, transfer, hypothecate, mortgage, encumber, or convey, or subject to or
permit to exist upon or be subjected to any lien or charge, this Lease or any
interest under it (ii) allow any transfer of, or any lien upon, Tenant's
interest in this Lease by operation of law, (iii) sublet the Premises in whole
or in part or (iv) allow the use or occupancy of any portion of the Premises for
a use other than the Use or by anyone other than Tenant or Tenant's employees.
Tenant shall have the right to sublet or assign all or any portion of the
Premises to any related entity or affiliate of Tenant, by merger; acquisition,
consolidation, or any successor company, without Landlord's approval or consent.
Tenant shall provide written notice of any such assignment or sublease.

     Notwithstanding the foregoing, should any law governing Landlord's consent
to a sublease or assignment require Landlord to exercise reason in the
consideration of the granting or denying of consent, Landlord may take into
consideration the business reputation and creditworthiness of the proposed
subtenant or assignee; any required alteration of the Premises; the intended use
of the Premises by the proposed subtenant or assignee; the estimated pedestrian
and vehicular traffic in the Premises and to the Building which would be
generated by the proposed subtenant or assignee; any potential environmentally
hazardous activities engaged in by the proposed subtenant or assignee; and any
other factors which Landlord shall deem relevant; provided further, however,
that if Landlord does not consent to a sublease or assignment to any subtenant
or assignee which is a governmental agency, which is a present tenant in the
Building, or with whom Landlord or its agents has discussed tenancy within the
Building, same shall not be deemed to be unreasonable.

     B. If Tenant shall, with Landlord's prior consent as herein required,
sublet the Premises: (i) an amount equal to rental in excess of the Base Rent
and any Additional Rent herein provided to be paid, shall be for the benefit of
Landlord and shall be paid to Landlord promptly when due under any such
subletting as Additional Rent; and (ii) Landlord shall be entitled to a fee not
greater than an amount equal to six (6) months Base Rental as consideration for
any such consent.

     C. If Tenant Is an entity whose ownership not publicly held, and if during
the Term, the ownership of the control of Tenant changes, Tenant shall notify
Landlord of such change within five (5) days thereof, and Landlord, at Its
option, may at any time thereafter terminate this Lease by giving Tenant written
notice of said termination at least sixty (60) days prior to the date of
termination stated in the notice. The term "control" as used herein means the
power to directly or indirectly direct or cause the direction of the management
or policies of Tenant. A change or series of changes in ownership of stock which
would result in direct or indirect change in ownership by the stockholders or an
affiliated group or

                                      -10-
<PAGE>

stockholders of less than fifty (50%) percent of the outstanding stock shall not
be considered a change of control.

     D. Tenant shall, by notice in writing, advise Landlord of its intention
from, on and after a stated date (which shall not be less than sixty (60) days
after the date of the giving of Tenant's notice to Landlord) to assign this
Lease or sublet any part or all of the Premises for the balance or any part of
the Term, and, in such event, Landlord shall have the right, to be exercised by
giving written notice to Tenant within thirty (30) days after receipt of
Tenant's notice, to terminate this Lease with respect to the space described in
Tenant's notice as of the date stated in Tenant's notice for the commencement of
the proposed assignment or sublease. Tenant's notice shall include the name and
address of the proposed assignee or subtenant, a true and complete copy of the
proposed assignment or sublease, and sufficient information as Landlord deems
necessary to allow Landlord to determine the financial responsibility and
character of the proposed assignee or subtenant.

     If Tenant's notice covers all of the Premises and if Landlord exercises its
right to terminate this Lease with respect to such space, then the Term of this
Lease shall expire and end on the date stated in Tenant's notice for the
commencement of the proposed assignment or sublease as fully and completely as
if that date had been the Expiration Date. If, however, Tenant's notice covers
less than all of the Premises, and if Landlord exercises its right to terminate
this Lease with respect to such space described in Tenant's notice, then as of
the date stated in Tenant's notice for the commencement of the proposed
sublease, the Base Rent and Tenant's Proportionate Share as defined herein shall
be adjusted on the basis of the number of rentable square feet retained by
Tenant, and this Lease as so amended, shall continue thereafter in full force
and effect.

     E. Landlord's consent to any assignment or subletting shall not release
Tenant of liability under this Lease or permit any subsequent prohibited act,
unless specifically provided in such written consent. Tenant agrees to pay to
Landlord, on demand, all reasonable costs incurred by Landlord in connection
with any request by Tenant of Landlord in connection with any consent to any
assignment or subletting by Tenant.

     17. SUBORDINATION. Landlord may execute and deliver a mortgage or trust
deed in the nature of a mortgage (both sometimes hereinafter referred to as
"Mortgage") against the Building, the Project or any interest therein, including
a ground lease thereof ("Ground Lease") and sell and leaseback the Land. This
Lease and the rights of Tenant hereunder shall be and are hereby made expressly
subject and subordinate at all times to any ground lease of the Land or the
Building or both, now or hereafter existing and all amendments, renewals and
modifications thereto and extensions thereof, or to the lien of any Mortgage now
or hereafter encumbering any portion of the Project, and to all advances made or
hereafter to be made upon the security thereof, provided that any such
subordination at all times shall be subject to the right of Tenant to remain in
possession of the Premises under the terms of this Lease for the Term,
notwithstanding any default under the relevant Ground Lease or Mortgage, or
after termination of said Ground Lease or foreclosure of the Mortgage or any
sale pursuant thereto, so long as Tenant is not in default under this Lease.
Tenant agrees to execute and deliver such instruments subordinating this Lease
to any such Ground Lease or to the lien of any such Mortgage as may be requested
in writing by Landlord from time to time and Tenant agrees to return to Landlord
any such instrument fully executed within ten (10) days of receipt thereof by
Tenant. Notwithstanding anything to the contrary contained herein, any mortgagee
under a Mortgage may, by notice in writing to Tenant, subordinate its Mortgage
to this Lease.

     In the event of the cancellation or termination of any such Ground Lease
described above in accordance with its terms or by the surrender thereof,
whether voluntary, involuntary or by operation of law, or by summary
proceedings, or the foreclosure of any such Mortgage by voluntary agreement or
otherwise, or the commencement of airy judicial action seeking such foreclosure,
Tenant, at the request of

                                      -11-
<PAGE>

the new landlord, shall attorn to and recognize such ground lessor, mortgagee or
purchaser in foreclosure as Tenant's landlord under this Lease. Tenant agrees to
execute and deliver at any time upon request of such ground lessor, mortgagee,
purchaser, or their successors, any instrument to further evidence such
attornment.

     Tenant agrees to give the holder of any Mortgage, by registered or
certified mail, a copy of any notice of default served upon Landlord by Tenant,
provided that prior to such notice Tenant has received notice (by way of service
on Tenant of a copy of an assignment of rents and leases, or otherwise) of the
address of such mortgagee and containing a request therefor. Tenant further
agrees that if Landlord shall have failed to cure such default within the time
provided for in this Lease, then said mortgagee shall have an additional thirty
(30) days after receipt of notice thereof within which to cure such default or,
if such default cannot be cured within that time, then such additional time as
may be necessary, if, within such thirty (30) days, any mortgagee has commenced
and is diligently pursuing the remedies necessary to cure such default
(including but not limited to commencement of foreclosure proceedings, if
necessary to effect such cure). Such period of time shall be extended by any
period within which such mortgage is prevented from commencing or pursuing such
foreclosure proceedings by reason of Landlord's bankruptcy. Until the time
allowed as aforesaid for said mortgagee to cure such defaults has expired
without cure, Tenant shall have no right to, and shall not, terminate this Lease
on account of default. This Lease may not be modified or amended so as to reduce
the rent paid hereunder or shorten the Term, or so as to adversely affect in any
other respect to any material extent the rights of Landlord, nor shall this
Lease be canceled or surrendered, without the prior written consent, in each
instance, of any ground lessor or mortgagee.

     18. CERTAIN RIGHTS RESERVED TO LANDLORD. Landlord reserves and may exercise
the following tights without affecting Tenant's obligations hereunder:

     A. To change the name or street address of the Building;

     B. To install and maintain a sign or signs on the interior or exterior of
the Building;

     C. To have access for Landlord and any other tenants of the Building to any
mail chutes located on the Premises according to the rules of the United States
Postal Service;

     D. To designate all sources furnishing sign painting and lettering ice,
drinking water, towels, food, beverages, vending machines and toilet supplies,
lamps and bulbs used on the Premises;

     E. To decorate, remodel, repair, alter or otherwise prepare the Premises
for reoccupancy if Tenant vacates the Premises prior the expiration of the Term;

     F To retain at all times passkeys to the Premises;

     G. To grant to anyone the exclusive right to conduct any particular
business or undertaking in the Building;

     H. To exhibit the Premises to others and to display "For Rent" signs on the
Premises;

     I. To close the Building after regular working hours and on the holidays;
subject, however, to Tenant's rights to admittance, under such reasonable
regulations as Landlord may prescribe from time to time, which may include by
way of example but not of limitation. To require that persons entering or
leaving the Building identify themselves to a watchman by registration or
otherwise and that said persons

                                      -12-
<PAGE>

establish their right to enter or leave the Building, and provided, that
Landlord shall not be liable for the failure to admit any person to the
Building;

     J. To approve the weight, size and location of safes or other heavy
equipment or articles, which articles may be moved in, about, or out of the
Building or Premises only at such times and in such manner as Landlord shall
direct, and in all events, at Tenant's sole risk and responsibility;

     K. To take any and all measures, including inspections, repairs,
alterations, decorations, additions and improvements to the Premises or to the
Building and temporary closures of the Building, as may be necessary or
desirable for the safety, protection or preservation of the Premises or the
Building or Landlord's interests or the interest of other tenants, or as may be
necessary or desirable in the operation of the Building.

     Landlord may enter upon the Premises and may exercise any or all of the
foregoing rights reserved without being deemed guilty of an eviction or
disturbance of Tenant's use or possession and without being liable in any manner
to Tenant and without abatement of rent or affecting any of Tenant's obligations
hereunder.

     19. HOLDING OVER. If Tenant retains possession of the Premises or any part
thereof after the termination of the Term, or any extension thereof, by lapse of
time and otherwise, Tenant shall pay Landlord monthly rental, at double the rate
payable for the month immediately preceding said holding over (including
increases for Rent Adjustment which Landlord may reasonably estimate), computed
on a per-month basis, for each month or part thereof (without reduction for any
such partial month) that Tenant thus remains in possession, and in addition
thereto, Tenant shall pay Landlord all damages, consequential as well as direct,
sustained by reason of Tenant's retention of possession. Alternatively, at the
election of Landlord expressed in a written notice to Tenant and not otherwise,
such retention of possession shall constitute a renewal of this Lease for one
(1) year. The provisions of this Section 19 do not exclude Landlord's right of
re-entry or any other right hereunder. Any such extension or renewal shall be
subject to all other terms and conditions herein contained.

     20. LANDLORD'S REMEDIES.

     A. Each of the following shall constitute a breach of this Lease by Tenant:
(i) Tenant fails to pay any installment or other payment of rent, including,
without limitation Base Rent, Rent Adjustment Deposits or Rent Adjustment within
five (5) days of the date that Tenant receives a notice from Landlord stating
that the relevant payment is delinquent; (ii) Tenant fails to observe or perform
any of the other covenants, conditions or provisions of this Lease or under the
Workletter to be observed or performed by Tenant and fails to cure such default
within fifteen (15) days after written notice thereof to Tenant; (iii) the
interest of Tenant in this Lease is levied upon under execution or other legal
process; (iv) a petition is filed by or against Tenant to declare Tenant
bankrupt or seeking a plan of reorganization or arrangement under any chapter of
the Bankruptcy Act or any amendment, replacement or substitution therefor, or to
delay payment of, reduce or modify Tenant's debts, or any petition is filed or
other action taken to reorganize or modify Tenant's capital structure or upon
the dissolution of Tenant; (v) Tenant is declared insolvent by law or any
assignment of Tenant's property is made for the benefit of creditors, or a
receiver is appointed for Tenant or Tenant's property; or (vi) Tenant abandons
the Premises.

     B. In the event of any breach of this Lease by Tenant, Landlord at its
option, without further notice or demand to Tenant, may, in addition to all
other rights and remedies provided in this Lease, at law or in equity:

                                      -13-
<PAGE>

          (i) terminate this Lease and Tenant's right of possession of the
     Premises, and recover all damages to which Landlord is entitled under law,
     specifically including, without limitation, rent for the balance of the
     Term, all Landlord's expenses of reletting (including repairs, alterations,
     improvements, additions, decorations, legal fees and brokerage
     commissions); or

          (ii) terminate Tenant's right of possession of the Premises without
     terminating this Lease, in which event Landlord may, but shall not be
     obligated to, relet the Premises, or any part thereof, for the account of
     Tenant, for such rent and term and upon such terms and conditions as are
     acceptable to Landlord.

     For purposes of such reletting, Landlord is authorized to decorate, repair,
alter and improve the Premises to the extent reasonably necessary. If Landlord
fails or refuses to relet the Premises or if the Premises are relet and a
sufficient sum not be realized therefrom after payment of all Landlord's
expenses of reletting (including repairs, alterations, improvements, additions,
decorations, legal fees and brokerage commissions) to satisfy the payment when
due of rent reserved under this Lease for each such monthly period or if the
Premises have been relet, Tenant shall pay any such deficiency monthly. Tenant
agrees that Landlord may file suit to recover any sums due to Landlord hereunder
from time to time and that such suit or recovery of any amount due Landlord
hereunder shall not be any defense to any subsequent action brought for any
amount not then reduced to judgment in fever of Landlord. In the event Landlord
elects, pursuant to this Section 20B, to terminate Tenant's right of possession
only, without terminating this Lease, Landlord may, at Landlord's option, enter
into the Premises, remove Tenant's signs and other evidences of tenancy, and
take and hold possession thereof as provided in Section 21 hereof, provided such
action shall not terminate this Lease or release Tenant, in whole or in part,
from Tenant's obligation to pay the rent reserved hereunder for the Term or from
any other obligation of Tenant under this Lease. Any and all property which may
be removed from the Premises by Landlord pursuant to the authority of the Lease
or of law, to which Tenant is or may be entitled, may be handled, removed or
stored by Landlord at the risk, cost and expense of Tenant, and Landlord shall
in no event be responsible for the value, preservation or safekeeping thereof.
Tenant shall pay to Landlord, upon demand, any and all expenses incurred in such
removal and all storage charges against such property so long as the same shall
be in Landlord's possession or under Landlord's control. Any such property of
Tenant not retaken from storage by Tenant within thirty (30) days after the end
of the Term, however terminated, shall be conclusively presumed to have been
conveyed by Tenant to Landlord under this Lease as a bill of sale without
further payment or credit by Landlord to Tenant. Tenant hereby grants to
Landlord a first lien upon the interest of Tenant under this Lease to secure the
payment of monies due under this Lease which lien may be enforced in equity. Any
default by Tenant of any term or condition hereof other than the payment of sums
due hereunder may be restrained or enforced by injunction.

     C. Tenant shall pay upon demand, all costs and expenses, including
reasonable attorney's fees, incurred by Landlord in enforcing the observance and
performance by Tenant of all covenants, conditions and provisions of this Lease
to be observed and performed by Tenant, or resulting from Tenant's default under
this Lease.

     D. If the term of any lease, other than this Lease, made by Tenant for any
Premises in the Building shall be terminated or terminable after the making of
this Lease because of any default by Tenant under such other lease, such fact
shall empower Landlord, at Landlord's sole opinion, to terminate this Lease by
notice to Tenant.

     21. SURRENDER OF POSSESSION. Upon the expiration or other termination of
the Term, Tenant shall quit and surrender to Landlord the Premises, broom clean,
in good order and condition, ordinary

                                      -14-
<PAGE>

wear excepted, surrender all keys to the Premises to Landlord, and Tenant shall
remove all of its property except as otherwise specifically provided herein.

     If Tenant does not remove its property of every kind and description from
the Premises prior to the end of the term, however ended, at Landlord's option,
Tenant shall be conclusively presumed to have conveyed the same to Landlord
under this Lease as a bill of sale without further payment or credit by Landlord
to Tenant and Landlord may remove the same and Tenant shall pay the cost of such
removal to Landlord upon demand. Tenant's obligation to observe or perform this
covenant shall survive the expiration or other termination of the term of this
Lease.

     22. [Intentionally omitted]

     23. COVENANT AGAINST LIENS. Tenant has no authority or power to cause or
permit any lien or encumbrance of any kind whatsoever, whether created by act of
Tenant, operation of law or otherwise, to attach to or be placed upon Landlord's
title or interest in the Building, the Project or Premises, and any liens and
encumbrances created by Tenant shall attach to Tenant's interest only. Tenant
covenants and agrees not to suffer or permit any lien of mechanics or
materialmen or others to be placed against the Land, Building or the Premises
with respect to work or services claimed to have been performed for or materials
claimed to have been furnished to Tenant or the Premises, and in case of any
such lien attaching, Tenant covenants and agrees immediately to cause it to be
released and removed of record.

     24. TENANT'S PAYMENT UPON EXECUTION.

     A. As additional security for the faithful and prompt performance of its
obligation hereunder, Tenant has concurrently with the execution of this lease
paid to Agent the Security Deposit described in Section 1 hereof. Said Security
Deposit need not be segregated and may be applied by Landlord for the purpose of
curing any default or defaults of Tenant hereunder, in which event Tenant shall
replenish said deposit in full by promptly paying to Landlord on demand the
amount so applied. Landlord shall not pay any interest on said deposit, except
as may be required by law. If Tenant has not defaulted hereunder and Landlord
has not applied said deposit to cure a default, or Landlord has applied said
deposit to cure a default and Tenant has replenished the same, then said
deposit, or such remaining portion thereof, shall be paid to Tenant after the
termination of this Lease. Said deposit shall not be deemed an advance payment
of Rent or measure of Landlord's damages or any default hereunder by Tenant.

     B. Notwithstanding anything to the contrary herein set forth, the Monthly
Base Rent payable for the first month of the Term shall be due and paid to
Landlord concurrently upon the execution hereof by Tenant.

     25. RULES AND REGULATIONS. Tenant shall occupy and use the Premises during
the Term for the purpose above specified and none other and shall comply with
the following provisions:

     A. Tenant will not make or permit to be made any use of the Premises which,
directly or indirectly is forbidden by public law, ordinance, or government
regulation of which may be dangerous to persons or property, or which may
invalidate or increase the premium cost of any policy of insurance carried on
the Building or covering its operations; Tenant shall not do, or permit to be
done, any act or thing upon the Premises which will be in conflict with fire
insurance policies covering the Building. Tenant at its sole expense shall
comply with all rules, regulations or requirements of the local inspection and
Rating Bureau, or any other similar body, and shall not do or permit anything to
be done upon said Premises or bring or keep anything thereon in violation of
rules, regulations, or requirements of the Fire Department, local inspection and
Rating Bureau, Fire Insurance Rating Organization or other authority

                                      -15-

shall be installed by Landlord at Tenant's cost and in such manner, character
and style as Landlord may approve in writing;

     C. Tenant shall not advertise the business, profession or activities of

address of Tenant, and shall never use any picture or likeness of the Building
in any circulars, notices, advertisements or correspondence without Landlord's
express consent in writing;

animal shall be brought or permitted to be in the Building or any part thereon;

     F. Tenant shall not make or permit any noise or odor that is objectionable

create or maintain a nuisance thereon, and shall not disturb, solicit or canvass
any occupant of the Building, and shall not do any act tending to injure the
reputation of the Building;

     G. Tenant shall not install any musical instrument or equipment in the
Building or any antennas, aerial wires or other equipment inside or outside the
Building, without, in each and every instance, prior approval in writing by
Landlord. The use thereof, if permitted, shall be subject to control by Landlord
to the end that others shall not be disturbed or annoyed;

     H. Tenant shall not waste water by tying, wedging or otherwise fastening
open, any faucet;

     I. No additional locks or similar devices shall be anchored to any door or
window. No keys for any door or window other than those provided by Landlord
shall be made. If more than two keys for one lock are desired by Tenant,
Landlord may provide the same upon payment by Tenant. Upon termination of this
Lease or of Tenant's possession, Tenant shall surrender all keys of the Premises
and Building and shall make known to Landlord the explanation of all combination
locks on safes, cabinets, and vaults;

     J. Tenant shall be responsible for protecting the demised Premises and all
property located therein and for the safety of all persons therein;

     K. If Tenant desires telegraphic, telephonic, burglar alarm or signal
service, Landlord will, upon request, direct where and how connections and all
wiring for such service shall be introduced and run. Without such directions, no
boring, cutting, or installation of wires or cables is permitted;

     L. Shades, draperies or other forms of inside window covering must be of
such shape, color and material as approved by Landlord;

     M. Tenant shall pay, as a late charge and to defray Landlord's increased

<PAGE>

amount equal to five (5%) percent of the amount due (but in no event shall the
amount of such late charge exceed an amount based upon the highest legally
permissible rate chargeable at anytime by Landlord under the circumstances).
Should Tenant make a partial payment of past due amounts, the amount of such
partial payment shall be applied first to reduce all accrued and unpaid late
charges, in inverse order of their maturity, and then to reduce all other past
due amounts, in inverse order of their maturity;

     N. Tenant shall not overload any floor. Safes, furniture and all large
articles shall be brought through the Building and into the Premises at such
times and in such manner as Landlord shall direct and at Tenant's sole risk and
responsibility. Only professional movers will be allowed to move Tenants into

furnish Certificates of Insurance to Landlord, and must agree to cooperate with
Landlord's requirements and restrictions. Landlord reserves the right to
prohibit specific movers from the Premises (NORTH SHORE MOVERS AND JOEY'S
MOVERS, AND ANY AFFILIATED FIRMS, ARE PROHIBITED). Tenant shall list all
furniture, equipment and similar articles to be removed from the Building, and
that list must be approved by the Office of the Building or by a Landlord

     Q. Tenant shall not install in the Premises any equipment that uses a
substantial amount of electricity without the advance consent of Landlord.
Tenant shall ascertain from Landlord the maximum amount of electric current
which can safely be used in the Premises, taking into account the ability of the
electric wiring in the Building of the Premises and the needs of other tenants
in the Building and shall not use more than such safe capacity. Landlord's
consent to the installation of electric equipment shall not relieve Tenant front
the obligation not to use more electricity in such safe capacity;

     R. Tenant may not install carpet padding or carpet by means of a mastic,
glue or cement without Landlord's prior written consent. Such installation shall
be by tackless strip or double-faced tape only;

covenant of this Section 25, Tenant shall pay to Landlord all damages caused by
such breach and shall so pay to Landlord as additional rent an amount equal to

<PAGE>

may from time to time adopt on such reasonable notice to be given as Landlord
may elect. Nothing in this lease shall be construed to impose upon Landlord any
duty or obligation to enforce provisions of this Section 25 or any rules and
regulations hereafter adopted, to the terms, covenants or conditions of any
other lease as against any other tenant, and Landlord shall not be liable to
Tenant for violation of the same by any other tenant, its servants, employees,
agents, visitors or licensees.

     26. USE OF PREMISES AND PARKING.

     The Tenant shall use the Premises for general office operations during
normal business hours between 7:00 A.M. and 7:00 P.M. weekdays and 7A.M. and 1
P.M. Saturdays ("Normal Business Hours"). Regular, consistent operations outside
of these days and hours shall place an undue burden on the Building's
facilities. Tenant agrees to discontinue such operations upon written notice
from Landlord. If Tenant does not discontinue such operations within ten (10)
days of notice, Tenant shall pay to Landlord, as Additional Rent, the sum of One
Hundred Dollars ($100.) per day per employee, invitee, or agent who is
conducting business operations on the Premises outside of Normal Business Hours.
Failure to pay this amount when billed shall constitute a default of this Lease.

     27. MISCELLANEOUS.

     A. No payment by Tenant or receipt by Landlord of a lesser amount than any
installment or payment of rent due shall be deemed to be other than a payment on
account of the amount due and no endorsement or statement on any check or any
letter accompanying any check or payment of rent shall be deemed an accord and
satisfaction, and Landlord may accept such check or payment without prejudice to
Landlord's right to recover the balance of such installment or payment of rent
or pursue any other remedies available to Landlord. No receipt of money by
Landlord from Tenant after the termination of this Lease or after the service of
any notice or after the commencement of any suit, or after final judgment for
possession of the Premises shall reinstate, continue or extend the term of this
Lease or affect any such notice, demand or suit.

     B. No waiver of any default of Tenant hereafter shall be implied from any
omission by Landlord to take any action on account of such default, and if such
default be repeated, no express waiver shall affect any default other than the
default specified in the express waiver and that only for the time and to the
extent therein stated.

     C. The words "Landlord" and "Tenant" wherever used in the Lease shall be
construed to mean plural when necessary, and the necessary grammatical changes
required to make the provisions hereof apply either to corporations or
individuals, men or women, shall in all cases be assumed as though in each case
fully expressed. The term "Tenant" shall include Tenant's agents, employees,
contractors, officers, invitees, successors and others using the Premises with
the expressed or implied permission of Tenant.

     D. Each provision hereof shall extend to and shall, as the case may
require, bind and inure to the benefit of Landlord and Tenant and their
respective heirs, legal representatives, successors and assigns in the event
this Lease has been assigned with the express written consent of Landlord;
provided, however; this provision shall not be construed to permit any
assignment or subletting by Tenant.

     E. The execution of this Lease by Tenant and delivery of such to Landlord
or Landlord's agent does not constitute a reservation of or option for the
Premises or an agreement to enter into a Lease. This Lease shall become
effective only if and when Landlord executes and delivers same to Tenant;
provided, however, the execution and delivery by Tenant of this Lease to
Landlord or Landlord's Agent shall constitute an irrevocable offer by Tenant to
lease the Premises and the terms and conditions herein

                                      -18-
<PAGE>

contained, which offer may not be withdrawn or invoked for 30 days after such
execution and delivery. If Tenant is a corporation, partnership, association or
any other entity, it shall deliver to Landlord, concurrently with the delivery
to Landlord of an executed Lease, certified resolutions of Tenant's directors,
or another governing person of body authorizing execution and delivery of this
Lease and the performance by Tenant of its obligations hereunder and the
authority of the party executing the lease as having been duly authorized to so
do.

     F. All amounts (unless otherwise provided herein, and other than the Base
Rent and Rent Adjustment, which shall be due as hereinbefore provided) owed by
Tenant to Landlord hereunder shall be deemed additional rent and be paid within
ten (10) days from the date Landlord renders statements of account therefor. All
such amounts (including Base Rent and Rent Adjustment) shall bear interest from
the date due until the date paid the rate of four (4%) percent above the prime
rate of interest published by LaSalle National Bank of Chicago on the date that
any payment is due, or at the maximum legal rate of interest, allowed by law, if
such maximum legal rate is applicable and lower. Whenever the term "Rent" is
referred to in this Lease, it shall include, Base Rent, Rent Adjustment and all
additional rent.

     G. All riders and exhibits attached to this Lease referred to herein be
hereby made a part of this Lease as though inserted in this Lease.

     H. The headings of sections are for convenience only and do not limit or
construe the contents of the sections.

     I. If Tenant shall occupy the Premises prior to the beginning of the term
of this Lease with Landlord's consent, all the provisions of this Lease shall be
in full force and effect as soon as Tenant occupies the Premises.

     J. Should any mortgage, leasehold or otherwise, require a modification or
modifications of this Lease, which modification or modifications will not bring
about any increased cost or expense to Tenant or in any other way substantially
change the rights and obligations of Tenant hereunder, then and in such event,
Tenant agrees that this Lease may be so modified.

     K. Tenant represents that Tenant has dealt directly with and only with
Agent and the Cooperating Broker listed in Section 1 hereof as brokers in
connection with this Lease and that, insofar as tenant knows, no other broker
negotiated this Lease or is entitled to any commission in connection therewith.
Tenant shall indemnify and hold Landlord, Owner and Owner's partners and their
respective agents and employees harmless from all claims of any other broker or
brokers in connection with this Lease.

     L. Tenant shall at any time and from time to time upon not less than ten
(10) days prior written request from Landlord execute, acknowledge and deliver
to Landlord, in form reasonably satisfactory to Landlord and/or Landlord's
mortgagee or purchaser, a written statement certifying (if true) that Tenant has
accepted the Premises, that this Lease is unmodified and in full force and
effect (or if there have been modifications, that the same are in full force and
effect as modified and stating the modifications), that Landlord is not in
default hereunder, the date to which the Rent and other charges have been paid
in advance, if any, and such other accurate certifications as may reasonably be
requested by Landlord or Landlord's mortgagee or purchaser, and agreeing to give
copies to any mortgagee of Landlord of all default notices sent or delivered to
Tenant by Landlord. It is intended that any such statement delivered pursuant to
this subsection may be relied upon by the relevant purchaser or mortgagee of the
Premises and their respective successors and assigns.

                                      -19-

     M. Landlord's or Owner's title is and always shall be paramount to the
title of Tenant and nothing herein contained shall empower Tenant to do any act,
which can, shall or may encumber such title.

     N. The laws of the State of Illinois shall govern the validity, performance
and enforcement of this Lease.

     O. If any term, covenant or condition of this Lease or application thereof
to any person or circumstance shall, to any extent, be invalid or unenforceable,
the remainder of this Lease, or the application of such term, covenant or
condition to persons or circumstances other than those as to which it Is held
invalid or unenforceable, shall not be affected thereby and each term, covenant
or condition of this Lease shall be valid and be enforced to the fullest extent
permitted by law.

     P. Tenant warrants and represents that it has full power and authority to
execute this Lease. In the event Tenant is a general partnership or consists of
two or more individuals, all present and future partners or individuals, as
applicable, shall be jointly and severally liable hereunder.

     Q. Landlord has no obligation pursuant to this Lease except as expressly
provided for herein. Landlord's liability hereunder shall cease upon the
transfer of Landlord's interest in this Lease.

     R. This Lease sets forth all the covenants, promises, agreements,
conditions and understandings between Landlord and Tenant concerning the
Premises and there are no covenants, promises, agreements, conditions or
understandings, either oral or written, between them other than as herein set
forth, except as herein otherwise provided, and no subsequent alteration,
amendment, change or addition to this Lease shall be binding upon Landlord or
Tenant unless reduced to writing and signed by them.

     S. Notices hereunder shall he in writing and shall be deemed given when
received if:

          (i) served by Landlord upon Tenant by leaving a notice at the Premises
     or forwarding through certified or registered mail, postage prepaid, to
     Tenant at the Premises.

          (ii) served by Tenant upon Landlord when addressed to Landlord and
     served by certified or registered mail, postage prepaid, to Landlord's
     agent at the address set forth in Section 1 or to such other address and
     parties as notified by Landlord.

     T. This Lease does not grant any rights to light or air over or about the
real property of Landlord. Landlord specifically excepts and reserves to itself
the use of any roofs, the exterior portions of the Project, all rights to and
the land and improvements below the improved floor level of the Project, to the
improvements and air rights above the Project and to the improvements and air
rights located outside the demising walls of the Project and to such areas
within the Project required for installation of utility lines and other
installations required to serve any occupants of the Project, and to maintain
and repair same, and no rights with respect thereto are conferred upon Tenant,
unless otherwise specifically provided herein.

     28. QUIET ENJOYMENT. Subject to the provisions of this Lease, Landlord
covenants that Tenant, on paying the rent required under and performing the
covenants of this Lease on its part to be performed, shall and may peaceably
have, hold and enjoy the Premises for the Term.

     29. PARKING. Tenant acknowledges that any utilization of more than one (1)
parking stall per two hundred (200) rentable square feet in the Premises (the
"Threshold Number," said Threshold Number

                                      -20-
<PAGE>

being obtained by dividing the rentable square footage of the Premises by 200
and then rounding to the nearest whole number) may cause Landlord to be unable
to provide satisfactory parking accommodations for the other tenants in the
Building. Therefore, if at any time during the Term the number of Tenant
Representatives (as herein defined) occupying the Premises (i.e., being present
on the Premises for last three (3) hours in any particular day) exceeds the
Threshold Number, Landlord shall be entitled to notify Tenant that Landlord
intends to invoke the remedies set forth in herein below in this Paragraph 30 in
an effort address its parking concerns. If within three (3) business days of its
receipt of such notice from Landlord, Tenant has not reduced its Tenant
Representatives to the Threshold Number, then Tenant shall be in default and
Landlord shall be entitled, in addition to its other remedies under this Lease,
to charge Tenant one hundred dollars ($100.00) per day for each tenant
Representative occupying the Premises in excess of the Threshold Number. Such
per diem penalties shall remain in effect until such time as Tenant provided
Landlord with reasonably satisfactory evidence that tenant Representatives no
longer exceed the Threshold Number. As used herein, "Tenant's Representatives"
shall mean all officers, partners employees, consultants, subtenants, and
contractual personnel occupying the Premises. Tenant hereby grants to Landlord
the right to inspect the Premises, from time to time and at any reasonable time,
for purposes of determining the number of Tenant Representatives occupying the
Premises.

     IN WITNESS WHEREOF, this Lease has been duly executed by the parties
hereto, as of the day and year first above written.
