                                 BUILDING LEASE


         THIS BUILDING LEASE (the "LEASE") is made as of November 17, 2000 by
and between BRADLEY ASSOCIATES LIMITED PARTNERSHIP, an Illinois limited
partnership or its assignee ("LANDLORD") and SUREBEAM CORPORATION, a Delaware
corporation ("TENANT").


                                    RECITALS:

         A. Landlord is about to purchase that certain tract of real estate and
improvements commonly known as 300 Regency Drive, Glendale Heights, Illinois,
more particularly described on Exhibit A (the "PROPERTY"). The improvements upon
the Property consist of a single story industrial building containing about
56,046 square feet on a parcel that consists of approximately 3.926 acres.

         B. Landlord has never been in possession or control of the Property.

         C. Concurrently with its acquisition of ownership of the Property,
Landlord desires to lease the Property to Tenant, and Tenant desires to lease
the Property from Landlord, on the terms, conditions and provisions set forth in
this Lease.


1.       AGREEMENT TO LEASE

         Landlord leases to Tenant and Tenant leases from Landlord, the
Property, subject to the terms of this Lease and to the covenants, conditions,
agreements, easements, encumbrances and restrictions affecting the Property.


2.       TERM

         2.1      TERM.

         The term of this Lease commences 30 days after the date Landlord
notifies Tenant that Landlord acquired title to the Property and tenders
possession to Tenant, anticipated to occur on or before February 1, 2000 (the
"COMMENCEMENT DATE") and will end 20 years from the last day of the month in
which the Commencement Date occurs (the "EXPIRATION DATE"), unless terminated
pursuant to Section 2.2 below or unless sooner terminated as set forth in this
Lease. The term "LEASE YEAR" means each period of twelve (12) consecutive
calendar months starting on the 1st day of the month next succeeding the
Commencement Date. "PARTIAL LEASE YEAR" means the period between the
Commencement Date and the first day of the first Lease Year.

         2.2      RIGHT TO TERMINATE.

         Tenant has the right to terminate this Lease at the last day of the
12th Lease Year if Tenant provides written notice to Landlord that it elects to
terminate the term at that time. Such termination notice, if sent, must be
received by Landlord no sooner than the 180th day of the 10th Lease Year and no
later than the 1st day of the 11th Lease Year. Any termination notice delivered
to Landlord before or after those dates will not be effective and the Lease will
remain in full force.


                                  1.

3.       RENT

         3.1      FIXED ANNUAL RENT.

         Tenant agrees to pay Landlord or to such other person as Landlord may
direct, at such other address as Landlord may by notice in writing to Tenant
from time to time direct, fixed annual rent from and after the Commencement
Date, for each respective Lease Year or Partial Lease Year, (the "FIXED ANNUAL
RENT"), payable in equal successive monthly installments ("FIXED MONTHLY RENT"),
in advance on or before the first day of each calendar month included in the
Term. The Fixed Annual Rent for the first Lease Year is the sum of Three Hundred
Ninety-Two Thousand Three Hundred Twenty-Two Dollars ($392,322). Starting with
the second Lease Year and continuing for the remainder of the Term of this
Lease, the Fixed Annual Rent will increase by the "CPI ADJUSTMENT" described in
Paragraph 3.2 below. The payment of all Fixed Annual Rent and Fixed Monthly Rent
is payable without any prior demand and without any set-offs or deductions
whatsoever except (a) Tenant may set off or deduct from the Fixed Monthly Rent
sums equal to final awards made against Landlord in Tenant's favor by a court of
competent jurisdiction; and (b) Tenant is not required to pay rent if Tenant
loses possession of the Property as a result of a defect in Landlord's title to
the Property. Tenant's covenant to pay all Rent (as defined in paragraph 3.3
below) is independent of every other covenant in this Lease. If the Term
commences on a date other than the first day of the month, Rent for the Partial
Lease Year will be payable on the Commencement Date at the same rate as the
Fixed Annual Rent for the first Lease Year, prorated for the applicable number
of days.

         3.2      CONSUMER PRICE INDEX ADJUSTMENT.

                  (a) CONSUMER PRICE INDEX. For purposes of this Lease, the
"CONSUMER PRICE INDEX" is the Consumer Price Index for Urban Wage Earners and
Clerical Workers, U.S. City Average, All Items (1982/84=100), published by the
United States Department of Labor, Bureau of Labor Statistics.

                  (b) CALCULATION. Commencing on the first anniversary of the
Commencement Date and continuing on each succeeding anniversary during the Term
of this Lease, the Fixed Annual Rent will be increased by the CPI Adjustment in
an amount equal to the lesser of (i) 200% times the increase in the Consumer
Price Index measured from the first day of the month immediately preceding the
new Lease Year compared to the level of the Consumer Price Index one year prior
to such date; or (ii) two percent (2%). Each such adjustment of the Fixed Annual
Rent will remain in full force and effect throughout, and is payable in equal
monthly installments (in addition to Additional Rent), during the Lease Year in
which it become effective. In no event will the Fixed Annual Rent be reduced.
Landlord agrees to notify Tenant, in writing, of each increase. Tenant agrees to
pay the new Fixed Annual Rent from the applicable adjustment date. Landlord's
notice may be given after the applicable adjustment date, in which event, Tenant
agrees to pay Landlord the accrued rental adjustment for the time elapsed
between the effective date of the increase and Landlord's notice of such
increase within thirty (30) days after receipt of Landlord's notice.

                  (c) ALTERNATIVE INDEX. If (i) the 1982/84=100 index is no
longer used or if the manner in which the Consumer Price Index is determined by
the Department of Labor, in Landlord's judgment, is otherwise substantially
revised, the calculations will be appropriately adjusted to produce results
that, in Landlord's judgment, are as nearly equivalent as is reasonably possible
to the results which would have been achieved had the Consumer Price Index not
been discontinued or so revised, or (ii) the Consumer Price Index is
discontinued or is unavailable, Landlord will then have the right to substitute
another index reflecting changes in the cost of living or purchasing power of
the consumer dollar published by any other governmental agency, or if no such
index is then available, another index published by a major


                                     2.

bank or other financial institution or by a university or recognized
financial publication or by any other recognized authority, and commonly used
for such calculations within the general area of the property.

         3.3      INCLUSION IN "RENT".

         The Fixed Annual Rent, together with all Additional Rent payable under
this Lease (including without limitation Tenant's payments of Taxes and
Assessments) is collectively referred to as "RENT."

         3.4      MANNER OF PAYMENT.

         Tenant agrees to cause the Fixed Monthly Rent and all Additional Rent
payable monthly to be sent to Landlord by check or by wire transfer on the first
day of each month during the term of this Lease.

         3.5      LATE PAYMENT OF RENT.

         If the full amount of the Fixed Monthly Rent due from Tenant is not
paid on or before the 5th day of the month for which such Rent is due,
irrespective of whether such fifth day is a business day or holiday, then a late
charge in an amount equal to 5% of the Fixed Monthly Rent then due will be due
and payable, without the requirement of any prior notice by Landlord and without
any cure or grace period before the late charge is imposed. In addition, all
past due Rent and/or other sums due to Landlord pursuant to the terms of this
Lease which have not been paid by the fifth (5th) day of the month during which
such payment is due will bear interest at the Lease Interest Rate (as defined),
from the due date until paid by Tenant. Notwithstanding the foregoing, Landlord
will allow one grace period of fifteen (15) days every twelve (12) months before
interest accrues on past due Rent.

         3.6      SECURITY DEPOSIT.

         Tenant agrees to deposit with Landlord, upon the execution of this
Lease, the sum of $23,000.00 as the Security Deposit as security for the full
and faithful performance by Tenant of each and every term, provision, covenant
and condition of this Lease. If Tenant defaults in respect to any of the terms,
provisions, covenants and conditions of this Lease including, but not limited
to, payment of all Rent and other sums required to be paid by Tenant, Landlord
may use, apply or retain the whole or any part of the security so deposited for
the payment of such rent in default, for any sum that Landlord expends by reason
of Tenant's default including, without limitation, any damages or deficiency in
the reletting of the Premises, whether such damages or deficiency shall have
accrued before or after re-entry by Landlord. If any of the security deposit is
so used, applied or retained by Landlord at any time or from time to time,
Tenant promptly agrees, in each such instance, on written demand by Landlord,
pay to Landlord such additional sums as are necessary to restore the security
deposit to the original amount set forth in the first sentence of this section.
If Tenant fully and faithfully complies with all the terms, provisions,
covenants and conditions of this Lease, the balance of the security deposit will
be returned to Tenant after the following: (a) the time fixed as the expiration
of the Term of this Lease; (b) the removal of Tenant from the Premises; (c) the
surrender of the Premises by Tenant to Landlord in accordance with this Lease;
and (d) final determination of all amounts payable by Tenant and payment of
same. Tenant is not entitled to receive any interest on the security deposit
that may be commingled with other funds of Landlord. In the absence of evidence
satisfactory to Landlord of an assignment of the right to receive the security
deposit or the remaining balance, Landlord may return the security deposit to
the original Tenant, regardless of one or more assignments of this Lease.


                                    3.

4.       TAXES AND ASSESSMENTS

         4.1      TAXES.

         Tenant agrees to pay as Additional Rent for the Property, all taxes and
assessments, general and special, water rates, utilities and all other
impositions, ordinary and extraordinary, of every kind and nature whatsoever,
which may be levied, assessed or imposed upon the Property or upon any building
or improvements at any time situated on the Property, accruing or becoming due
and payable during the term of this Lease and any extension. All taxes are
calculated on an "accrual" basis, which means that Tenant is responsible for
taxes assessed and levied with respect to the period from and after the
Commencement Date, regardless of when such taxes are actually due or payable.
Pursuant to this Lease, the general taxes levied against the Property will be
prorated between Landlord and Tenant for the first year of the term as of the
Commencement Date. Taxes will also be prorated preliminarily as of the date of
expiration of the term of this Lease for the last year of the term (including
any extensions), on the basis of the most recent ascertainable real estate taxes
as applied to the most recent assessed valuation Property. After the expiration
of the term, including any extensions, Landlord and Tenant agree to reprorate
the general real estate taxes for the final Lease Year. Landlord or Tenant agree
to immediately pay to the other party (as appropriate) such amounts as are
reflected by such reproration. Benefit may be taken by Tenant of the provisions
of statute or ordinance permitting any assessment to be paid over a period of
years; however, Tenant agrees to pay all installments due during the term or any
extension. Tenant also agrees to pay any new tax of a nature not presently in
existence but which may hereafter be levied, assessed or imposed upon the
Landlord or upon the Property, if such tax is based upon or arise out of the
ownership, use of operation of the Property; provided, however, that for the
purpose of computing Tenant's liability for such new type of tax, the Property
will be considered as the only property of the Landlord. Landlord agrees to
forward to Tenant any tax bills, or assessment notices that it receives from
time to time.

         4.2      TAX IMPOUNDS.

         Tenant agrees to deposit monthly with Landlord, or such other entity as
Landlord may designate, on the first day of each and every month during the
Lease term or any extension, a sum equal to 1/12th of the aggregate amount of
the prior year's general real estate taxes and annual installments of special
assessments levied with respect to the Property, which monthly deposits will be
used as a fund to be applied to the payment of such general real estate taxes
and special assessments as they become due and payable. The existence of such
fund does not limit or alter Tenant's obligation to pay the taxes or assessments
for which the fund was created. Tenant must furnish Landlord with a copy of the
tax bill and such additional funds as may be necessary to pay the tax bill in
full, along with a request to pay the taxes at least fourteen (14) days prior to
the due date.

         4.3      TAXES DEFINED.

         Nothing contained in this Lease should be construed to require Tenant
to pay any franchise, inheritance, estate, succession or transfer tax of
Landlord or any income or excess profits tax assessed upon or in respect of any
income of Landlord or chargeable to or required to be paid by Landlord unless
such tax is specifically levied against the rental income of Landlord derived
under this Lease, as and for a substitute for the real estate taxes, in whole or
in part, upon the Property in which event the Rent will be considered as the
sole income of Landlord.

Property in compliance with all Environmental Laws and is responsible for
obtaining all governmental permits relating to the use or operation of the
Property required by Environmental Laws.

                  (b) Tenant will not permit to occur during the term of the

Materials is found on the Property, Tenant, at its own cost and expense, will
immediately take such action as is necessary to detain the spread of and remove
such Hazardous Material to the reasonable satisfaction of Landlord and the

the Property (i) at any time upon the request of Landlord's mortgagee or (ii) at
reasonable times not to exceed once every two years, and Tenant will cooperate

Landlord's choosing, and if any Hazardous Material arising out


                                   14.
<Page>


of a Tenant Release other than Allowable Hazardous Material is detected or if
a violation of any of the covenants contained in this Article 12 is
discovered, the fees and expenses of such consultant and such audit will be

                  (f) Tenant agrees to indemnify, defend, and hold harmless any

                           (5) any condition described in the Environmental
         Report.

         12.3     LANDLORD'S ENVIRONMENTAL COVENANTS.

         Landlord represents that to the best of its knowledge (a) the Property
is currently in compliance with all Environmental Laws; and (b) Landlord will
promptly notify Tenant and provide copies of any Environmental Notifications.

         12.4     SURVIVAL.

         The provisions of Sections 12.1, 12.2 and 12.3 will survive the
expiration or termination of this Lease.

         12.5     TENANT'S ACCEPTANCE.

         Landlord has provided Tenant with all the following documents in its
possession or control affecting the Property: (a) all building plans, surveys
and site plans (b) all environmental reports; and (c) all engineering reports
and evaluations. In addition, Tenant has inspected the Property to determine the
condition and suitability of the Property for the particular needs of Tenant.
Tenant plans to do extensive renovations to the Property, at Tenant's expense,
to adapt the Property to Tenant's needs. Landlord warrants to Tenant that all
mechanical, electric, plumbing, and HVAC operations serving the Premises will be
in working condition at the time Landlord tenders possession of the Premises to
the Tenant, but otherwise Tenant agrees to accept the Property "as is" and
"where is", without any representation or warranty of any kind by Landlord
concerning the physical condition of the Property or the compliance or
non-compliance of the Property with any applicable laws, codes or ordinances.

13.      CONDEMNATION

         13.1     SUBSTANTIAL CONDEMNATION.

         If all of the Property is taken as a result of the exercise of the
power of eminent domain or condemned for a public or quasi-public use or purpose
by any competent authority or sold to the condemning authority under threat of
condemnation, or in the event a portion of the Property is taken or sold as a
result of such event, and as a result, in the joint reasonable determination of
both Landlord and Tenant the balance of such Property cannot be used for the
same purpose


                                       15.
<Page>


as before such taking, sale or condemnation, then and in either of such
events, the term of this Lease will terminate as of the date of vesting of
title pursuant to such proceeding or sale. The total award, compensation or
damages received from such proceeding or sale (the "AWARD"), subject to the
rights of Landlord's mortgagee, will be paid to and be the property of
Landlord, whether the Award is made as compensation for diminution of the
value of the leasehold or the fee of the Property or otherwise. The Tenant
assigns to Landlord, all of Tenant's right, title and interest in and to the
Award, except that Tenant reserves the right to receive a separate award for
its moving and relocation expenses which do not diminish the Award to
Landlord. Tenant agrees to execute, immediately upon demand of Landlord, such
documents as may be necessary to facilitate collection by Landlord, or
Landlord's mortgagee, of any such award, compensation or damages.

         13.2     NON-SUBSTANTIAL CONDEMNATION.

         If only a part of the Property is taken as a result of the exercise of
the power of eminent domain or condemned for a public or quasi-public use or
purpose by any competent authority or sold to the condemning authority under
threat of condemnation, and as a result in the joint reasonable determination of
Landlord and Tenant the balance of the property can be used for the same purpose
as before such taking, sale or condemnation, this Lease will not terminate and
Tenant, at its sole cost and expense, will promptly repair and restore the
Property and all improvements. Any award, compensation or damages paid as a
consequence of such taking, sale, or condemnation, is payable to Landlord, or
Landlord's mortgagee, and will be disbursed in accordance with the provisions of
Section 9.3. Any sums not so disbursed may be retained by Landlord. Tenant
reserves the right to receive a separate award for Tenant's relocation expenses
and for improvements and equipment installed by Tenant at the Property, as long
as there is no diminution of the award granted to Landlord. If Tenant does not
commence the required repair or restoration within 30 days after written notice
from Landlord, and then diligently pursue the completion of same, the Tenant
will be deemed in default under this Lease unless the delay is caused by the
failure of Landlord or Landlord's mortgagee to disburse funds in a timely
manner. In addition to any remedy of Landlord provided for under this Lease, at
law or in equity, Landlord may retain the award, compensation or damages
remaining in the hands of Landlord.

         13.3     ALTERNATE FORM OF TAKING.

         For the purpose of this Lease, all amounts payable pursuant to any
agreement with any condemning authority which has been made in settlement of or
under threat of any condemnation, or other eminent domain proceeding affecting
the land, and/or the improvements shall be deemed to constitute an award made in
such proceeding; provided, however, that no such agreement shall be made with
any condemning authority by either Landlord or Tenant without the written
consent of the other, which consent shall not be unreasonably withheld or
delayed.


14.      RENT ABSOLUTE

         14.1     NET LEASE.

                  (a) This Lease is a net lease and, to the extent not otherwise
provided by law, will not terminate except as otherwise expressly provided, nor
will Tenant be entitled to any abatement or reduction, setoff, suspension,
counterclaim, defense or deduction with respect to any Rent, Additional Rent or
other sums payable, nor will the obligations of Tenant be affected, by reason
of: any damage to or destruction of the Property; any taking of all or any part
of the Property by condemnation or otherwise; the existence of any liens or
rights of others whatsoever with respect to the Property consented to by Tenant
or caused by an act or


                                      16.
<Page>


omission of Tenant; any lawful action of any governmental authority; or any
other cause whether similar or dissimilar to the foregoing. Nothing contained
in this Subsection 14.1(a) will be considered a waiver by Tenant of any
rights that it may have to bring a separate action with respect to any
default by Landlord, including an action for injunctive relief against
Landlord. The parties intend that the obligations of Tenant are separate and
independent covenants and agreements from the covenants and agreements of
Landlord and will continue unaffected unless such obligations shall have been
modified or terminated pursuant to an express provision of this Lease.

                  (b) Tenant remains obligated under this Lease in accordance
with its terms and may not take any action to terminate, rescind or avoid this
Lease, notwithstanding any bankruptcy, insolvency, reorganization, liquidation,
dissolution or other proceeding affecting Landlord.

                  (c) Except as otherwise specifically provided in this Lease,
Tenant waives all rights to terminate or surrender this Lease, or to any
abatement or abatement of Rent, Additional Rent or other sums payable under this
Lease.

of Landlord (provided that each such sublease is expressly made subject to the
provisions of this Lease) and Tenant may assign all its rights and interests
under this Lease, provided that any guarantor of this Lease furnishes to the
Landlord a written affirmation of the guaranty notwithstanding such assignment
or sublease. If Tenant assigns all its rights and interests under this Lease,
the assignee under such assignment must expressly assume all the obligations of
Tenant in an instrument approved by Landlord as to form and substance (which
approval will not be unreasonably withheld or delayed), delivered to Landlord at
the time of such assignment, and expressly be subordinate to this Lease. No
assignment or sublease made as permitted by this Paragraph 15.1 will affect or
reduce any of the obligations of Tenant, and all such obligations will continue
in full force and effect as obligations of a principal and not as obligations of
a guarantor or surety, to the same extent as though no assignment or subletting
had been made; provided that performance by any such assignee or sublessee of
any of the obligations of Tenant under this Lease will be deemed to be
performance by Tenant. No sublease or assignment made as permitted by this
Paragraph 15.1 imposes any obligations on Landlord or otherwise affect any of
the rights of Landlord under this Lease.

         15.2     NOTICE TO LANDLORD.

         Tenant agrees to deliver to Landlord a conformed copy of the assignment

Property, Tenant agrees to give notice to Landlord of the existence and term,
and of the name and address of the sublessee.

without Landlord's prior consent provided (a) Tenant notifies Landlord of such
sublease or assignment not less than ten (10) days prior to such sublease or
assignment, (b) Tenant delivers a copy of the executed sublease or assignment to
Landlord within ten (10) days of such subletting or assignment, (c) the
subletting or assignment shall be subject to all of the liabilities and
obligations set forth herein, (d) the sublease or assignment document does not
modify any provision of this Lease or any of Landlord's or Tenant's obligations
under the terms and conditions of this Lease in any manner, and (e) Tenant shall
not be released of any of its liabilities hereunder. No such sublease or
assignment shall be permitted under this section if the sublease or assignment

                           (2) Landlord may terminate this Lease upon ten (10)
         days written notice to Tenant if such default is not cured within such
         10 day period, in which event Landlord may repossess the Property and
         the term and the estate created of this Lease will expire and all
         rights of Tenant under this Lease will cease as of such termination
         date.

                           (3) Landlord may terminate Tenant's right of
         possession upon ten (10) days written notice to Tenant if such default
         is not cured within such 10 day period, may repossess the Property and
         remove all persons and property as Landlord may elect by forcible entry
         and detainer suit, by peaceful taking or otherwise, without terminating
         this Lease, in which event the right of Tenant possession of the
         Property shall cease and terminate as of such date. If Landlord elects
         to re-enter as provided or if Landlord takes possession pursuant to
         legal proceedings or pursuant to any notice provided for by law or
         termination of this Lease pursuant to clause (2) of this Section 20.2
         or termination of Tenant's right to possession pursuant to clause (3)
         of this Section 20.2 or otherwise as permitted by law, Tenant agrees to
         peaceably quit and surrender the Property to Landlord. In any such
         event, neither Tenant nor any person claiming through or under Tenant,
         by virtue of any statute or of an order of any court, will be entitled
         to possession or to remain in possession of the Property, or any part,
         but must promptly quit and surrender the Property to Landlord.

                           (4) Upon termination of this Lease pursuant to clause
         (2) of this Section 20.2 or repossession pursuant to clause (3) of this
         Section 20.2, Tenant agrees to pay to Landlord all Rent and other sums
         required to be paid by Tenant up to the time of such termination or
         repossession. From and after such termination or repossession until the
         end of what would have been the term of this Lease in the absence of
         such termination or repossession, Tenant is liable to Landlord for, and
         agrees to pay Landlord the sums of money ("CURRENT DAMAGES") that would
         have been payable by Tenant, as Rent and all other sums which be
         payable under this Lease by Tenant in the absence of such termination
         or repossession, less the proceeds, if any, actually received by
         Landlord as a result such repossession and subsequent reletting or
         other disposition of the Property, after deducting from such proceeds,
         the expenses, costs and payments of every kind Landlord which in
         accordance with the terms of this Lease would have been borne by Tenant
         and all of Landlord's expenses in connection with such realization of
         proceeds. Such Landlord expenses include all unpaid expenses incurred
         in obtaining possession, in altering, repairing and putting the
         Property in good order and condition and in reletting the Property or
         any part including reasonable fees of attorneys, architects, and other
         experts and any other reasonable and legitimate expenses. Tenant will
         pay such Current Damages monthly on the days on which Rent would have
         been payable under this Lease in the absence of such termination or
         repossession, and Landlord is entitled to recover the same from Tenant
         on each such day. Tenant also is liable for all sums otherwise payable
         by Tenant under this Lease including, but limited to, such expenses of
         Landlord, as well as for any such deficiency, and Landlord has the
         right from time to time to begin and successive actions or other legal
         proceedings against Tenant for the recovery of deficiency or damages or
         for a sum equal to any installments of Rent and any sums payable under
         this Lease and to recover the same upon the liability of Tenant. The
         liability survives the action to secure possession of the Property.
         Landlord is not required to wait to begin any such action or other
         proceedings until the date this Lease would have expired by limitation
         had there been no such Event of Default.

                           (5) At any time after any termination of this Lease
         pursuant to clause (2) of this Section 20.2, or termination of
         possession pursuant to clause (3) of this Section 20.2, whether or not
         Landlord has collected any Current Damage, Tenant will pay to Landlord,
         at Landlord's option and upon demand, as and for liquidated and agreed
         final damages ("FINAL DAMAGES") for Tenant's default and in lieu of all
         Current Damages beyond the date of such demand, an amount equal to the
         sum of (i) the excess, if any, of Rent and the sums which would be
         payable under this Lease from the


                                       21.
<Page>


         date of such demand (or, if it be earlier, the date to which Tenant
         satisfied in full its obligation under clause (4) of this Section 20.2
         to pay Current Damages) for what would be the then unexpired term of
         this Lease in the absence of such expiration or repossession,
         discounted at the rate of [...***...]% per year on the basis of a
         360-day year of twelve consecutive 30-day months, over the fair rental
         value of the Property at the time of such termination for the balance
         of such term, discounted at the same rate and in the same manner as
         above stated. Nothing in this Section limits or prejudices the right of
         Landlord, in any bankruptcy, reorganization or insolvency proceedings,
         to prove for and obtain as liquidated damages by reason of such
         termination, an amount equal to the maximum allowed by any statute or
         rule of law in effect at the time when, and governing the proceedings
         in which, such damages are to be proved, whether or not such amount is
         greater than, equal to, or less than such Final Damages.

         Notwithstanding the cure, grace or notice periods set forth above,
Tenant agrees and acknowledges that (i) sums remaining unpaid continue to accrue
interest during any such cure or grace period, at the Lease Interest Rate; (ii)
Tenant is not entitled to more than two (2) such written notices and cure or
grace periods in any consecutive 24 month period during the term of this Lease;
and (iii) in addition to any and all other remedies to which Landlord is
entitled for the non-payment or late payment of rent (including interest on sums
due but not yet received), Landlord is also entitled to collect a late charge as
set forth in Section 3.3.

         20.3     LANDLORD'S DEFAULTS AND TENANT'S REMEDIES.

         Each of the following events, occurrences or acts constitutes an `Event
of Default' by Landlord under this Lease:

                  (a) Failure to pay any sum required to be paid by Landlord
under this Lease and such default constitutes for thirty (30) days after receipt
of written notice; or

                  (b) Failure to observe or perform any of the other covenant or
conditions in this Lease which Landlord is required to observe and perform and
such failure continues for sixty (60) days after a written notice to Landlord,
provided however that if a non-monetary covenant is in default which by its
nature cannot be fully cured within such sixty (60) days and within such sixty
(60) days, Landlord takes all reasonable steps needed to commence its cure and
correction and diligently continues to prosecute such cure and does in fact cure
or correct such default within a reasonable period thereafter, then such
occurrence will not be a breach under this Lease; or

                  (c) If a default involves a Hazardous Materials condition for
which Landlord is responsible and is not cured by Landlord within a reasonable
period of time after receipt of written notice to Landlord.

         In addition to any other remedies specifically provided in this Lease,
Tenant may, at its option, terminate this Lease if Tenant's use and enjoyment of
the Property is disturbed due to a defect in Landlord's title in the Property,
unless such defect is cured within nine (9) months following receipt of written
notice from Tenant to Landlord and Landlord's mortgagee.

         20.4     WAIVER.

         Except as expressly provided in this Lease, Tenant waives, so far as
permitted by law, the service of any notice of intention to re-enter the
Property provided for in any statute, and Tenant also waives any and all right
of redemption or re-entry or re-possession in case Tenant is dispossessed by a
judgment or by warrant of any court or judge or in case of re-entry or
repossession by Landlord or in case of any expiration or termination of this
Lease. The terms




                                       22.
                                          * Confidential Treatment Requested
<Page>



"enter", "re-enter", "entry" or "re-entry" as used in this Lease are not
restricted to their technical legal meanings.

         No failure by Landlord or Tenant to insist upon the strict performance
of any agreement, term, covenant or condition or to exercise any right or remedy
consequent upon a breach, and no acceptance of full or partial rent during the
continuance of any such breach, shall constitute a waiver of any such breach or
of such agreement, term, covenant or condition. No agreement, term, covenant or
condition to be performed or complied with by Tenant or Landlord, and no breach
can be waived, altered or modified except by a written instrument executed by
Landlord or Tenant. No waiver of any breach will affect or alter this Lease, but
each and every agreement, term, covenant and condition will continue in full
force and effect with respect to any other then existing or subsequent breach.

         20.5     INJUNCTION.

         Upon any breach or threatened breach by Tenant of any of the
agreements, terms, covenants or conditions contained in this Lease, Landlord
will be entitled to enjoin such breach or threatened breach and will have the
right to invoke any right and remedy allowed at law or in equity or by statute.

         20.6     REMEDIES CUMULATIVE.

         Each right and remedy provided for in this Lease is cumulative and in
addition to every other right or remedy provided for in this Lease or now or
hereafter existing at law or in equity or by statute or otherwise, and the
exercise or beginning of the exercise by Landlord or Tenant of any one or more
of the rights or remedies provided for in this Lease or now or hereafter
existing at law or in equity or by statute or otherwise shall not preclude the
simultaneous or later exercise by the party in question of any or all other
rights or remedies provided for in this Lease or now or hereafter existing at
law or in equity or by statute or otherwise.

         20.7     RIGHT TO CURE DEFAULTS.

         Either party may, but is not obligated to, cure, any default by the
other party under this Lease if the other party fails to cure after the
applicable notice and cure period.


21.      EXPENSES OF ENFORCEMENT

         21.1     EXPENSES OF ENFORCEMENT.

         The losing party in any litigation agrees to pay upon demand all
expenses of the prevailing party, including reasonable attorneys' fees and court
costs (together with interest on the amount of such fees, costs and expenses at
the Lease Interest Rate) incurred either directly or indirectly in enforcing any
obligation under this Lease and in defending or otherwise participating in any
legal proceedings initiated by or on behalf the losing party under which the
prevailing party is not adjudicated to be in default under this Lease.


22.      SUBORDINATION TO MORTGAGES

         22.1     SUBORDINATION.

         Subject to paragraph 22.2, this Lease and the rights and interest of
Tenant are subject and subordinate to any and all present and future ground or
underlying leases of the Land and to the lien of any mortgages or trust deeds,
now or hereafter placed upon the Land, and to any advances made or to e, made
and all extensions, renewals, consolidations, modifications, and amendments
thereof, unless the holders of such mortgages or trust deed, or the lessors
under such ground lease or underlying leases require in writing that this Lease
be superior. Such subordination shall be automatic and self-operative, and shall
not require the execution of any


                                       23.
<Page>


further instrument to be effective. Notwithstanding the foregoing, Tenant shall
at Landlord's request or at the request of Landlord's mortgagee execute such
further instruments or assurances as Landlord or its mortgagee may reasonably
deem necessary to further evidence or confirm the subordination or superiority
of this Lease to any such mortgages, trust deeds, ground leases or underlying
leases.

         22.2     NON-DISTURBANCE AND ATTORNMENT.

         As a condition to the subordination set forth in Section 22.1 above,
Landlord agrees to deliver to Tenant, and Tenant agrees to execute, as soon as
practical after the execution, a non-disturbance and attornment agreement from
Landlord's present mortgagee, using such mortgagee's customary form. Landlord
further agrees that it shall be a condition to the subordination set forth in
Section 22.1 above with respect to any future mortgagee that Landlord deliver a
non-disturbance and attornment agreement from such future mortgagee, using such
mortgagee's then customary form Tenant agrees that no action taken by the
mortgagee to enforce the mortgage by foreclosure, or by accepting a deed in lieu
of foreclosure, or by resorting to any other remedies available to the
mortgagee, will terminate this Lease or invalidate any of the terms of this
Lease and that Tenant will attorn to the mortgagee, to the purchaser at a
foreclosure sale, or to a grantee in a voluntary conveyance, and will recognize
such entity as Landlord for the balance of the term of the Lease, providing that
the mortgagee will agree with the Tenant that, as long as the Tenant is not in
default under any of the terms of its Lease, the Tenant's possession will not be
disturbed by the mortgagee, except to the extent provided in this Lease. Such
attornment will be automatic and self-operative, and no further instrument is
required for such attornment to be effective. Notwithstanding the foregoing,
Tenant agrees, at the request of Landlord or Landlord's mortgagee, to execute
such further instruments as Landlord or its mortgagee may reasonably deem
necessary to further evidence or confirm the attornment and non-disturbance
agreement.


23.      INDEMNITY AND WAIVER

         23.1     TENANT'S INDEMNITY.

                  (a) Tenant agrees to protect, indemnify and save harmless
Landlord (and, if Landlord is a Trustee, the term "Landlord" for the purpose of
this Article 23 only, includes the Trustee, its agents, its beneficiary or
beneficiaries and their agents), the mortgagee or the holder of any lien or
mortgage upon the Property, the holder of any note secured by any such mortgage
(a "NOTEHOLDER") and any partner, officer, director or shareholder of Landlord,
any Noteholder, and any holder of any lien or mortgage upon the Property
(collectively, the "INDEMNIFIED PARTIES") from and against all losses,
liabilities, obligations, claims, damages, penalties, causes of action, suits,
demands1 or judgments of any nature, costs and expenses (including without
limitation, reasonable attorneys' fees and expenses) imposed upon, incurred by
or asserted against any Indemnified Party arising from, or out of, or by reason
of (a) any accident, injury to or death of persons or loss or damage to property
occurring on or about the Property or any part thereof or the adjoining
properties, sidewalks, curbs, streets or ways resulting from an act or omission
of Tenant or anyone claiming by, through or under Tenant; (b) or any failure on
the part of Tenant to perform or comply with any of the terms of this Lease; (c)
performance of arty labor or services or the furnishing of any materials or
other property in respect of the Property or any part thereof at the request or
on behalf of Tenant, (d) any instrument which Landlord is requested by Tenant to
execute pursuant to Sections 4.6 or 4,7, (e) any use, act or omission of Tenant
or its employees, agents, contractors, licensees, sublessees or invitees, and
(f) any contest referred to in Section 4.6 of this Lease. In case any action,
suit or proceeding is brought against Landlord by reason of any such occurrence,
Tenant will, at Tenant's sole expense, resist and defend such action, suit or
proceeding, or


                                     24.
<Page>


cause the same to be resisted and defended, provided that Landlord gives
timely notice to Tenant of any such action, suit or proceeding. All payments
due to Landlord hereunder shall be so much Additional Rent due on the
immediately following next rent payment date, together with interest at the
Lease Interest Rate from the date of Landlord's disbursement. The obligations
of Tenant under this Section 23.1 with respect to events or circumstances
occurring or existing prior to the expiration or termination of this Lease
shall survive the expiration or the termination of this Lease and shall not
be limited or affected by any other provision of this Lease requiring Tenant
to carry liability insurance.

         An Indemnified Party must give Tenant notice of the existence of any
claim with respect to which Tenant is responsible to indemnify and defend the
Indemnified Party under this Lease (whether or not pursuant to this Section
23.1), promptly after such claim is made upon the Indemnified Party; provided
(i) notice of any claim by any Indemnified Party shall serve as notice to Tenant
with respect to such claim from all Indemnified Parties, and (ii) failure to
provide such notice shall not diminish in any way Tenant's obligations to
indemnify or defend the Indemnified Parties, except as to the obligations to
indemnify the Indemnified Party or Parties upon which such claim was made and
which had notice of such claim, and then only to the extent Tenant is actually
prejudiced thereby. In circumstances in which the position of an Indemnified
Party may be adverse to the position of Tenant or any of its Affiliates, in such
Indemnified Party's reasonable judgment, such Indemnified Party may conduct its
own defense with its independent or in-house counsel at Tenant's expense. In all
other circumstances, (i) Tenant agrees to employ independent counsel reasonably
satisfactory to Landlord and the Noteholders on behalf of each affected
Indemnified Party to defend the claim at Tenant's expense, and (ii) each such
Indemnified Party agrees to use reasonable efforts to cooperate with Tenant and
the counsel employed by Tenant in conducting such defense. In any event, all
settlements of claims must be subject to the reasonable approval of each
affected Indemnified Party. Without limiting the generality of the foregoing, an
Indemnified Party will not be considered to be unreasonable in withholding its
consent to a proposed settlement of a claim if, in the sole discretion of such
Indemnified Party, such settlement might have an adverse effect on such
Indemnified Party (despite the payment of amounts due under the proposed
settlement by Tenant). An Indemnified Party's failure to reasonably cooperate as
described above, or an Indemnified unreasonable withholding of its consent to
the settlement of a claim recommended in writing Tenant, shall not diminish in
any way Tenant's obligations to indemnify or defend the Indemnified Parties,
except the Indemnified Party or Parties which fail to reasonably cooperate as
described above or unreasonably withhold consent to a settlement as set forth
above, and then only to the extent Tenant is actually prejudiced.

         23.2     WAIVER.

         Tenant waives all claims it may have against Landlord and Landlord's
agents for damage or injury to person or property sustained by Tenant or any
persons claiming through Tenant or by any occupant of the Property, or by any
other person, resulting from any part of the Property or any of' its
improvements, equipment or appurtenances becoming out of repair, or resulting
from any accident on or about the Property or resulting directly or indirectly
from any act or neglect of any person, other than a negligent act or omission by
Landlord, its officers, agents, employees or contractors. This Section 23.2
includes, but not by way of limitation, damage caused by water, snow, frost,
steam, excessive heat or cold, sewage, gas, odors, or noise, or caused by
bursting or leaking of pipes or plumbing fixtures, and shall apply equally
whether any such damage results from the act or neglect of Tenant or of any
other person, other than a negligent act or omission by Landlord, its officers,
agents, employees or contractors, and whether such damage be caused or result
from any thing or circumstance above mentioned or referred to, or to any other
thing or circumstance whether of a like nature


                                   25.
<Page>


or of a wholly different nature. All personal property belonging to Tenant or
any occupant of the Property that is in or on any part of the Property shall be
there at the risk of Tenant or of such other person only, arid Landlord shall
not be liable for any damage thereto or for the theft or misappropriation
thereof other than as a result of Landlord's gross negligence.

         23.3     LANDLORD'S INDEMNITY.

         Landlord agrees to protect, indemnify and save harmless Tenant and any
officer, director or shareholder of Tenant from and against any losses,
liabilities, claims, obligations, damages, penalties, causes of action, suits,
demands,, or judgments of any nature, costs and expenses (including reasonable
attorneys' fees and expenses arising out of any negligent act or negligent
omission caused by Landlord, its officers, employees, agents or contractors.

24.      SURRENDER

         24.1     SURRENDER.

         Upon the termination of this Lease whether by forfeiture, lapse of time
or otherwise, or upon the termination of Tenant's right to possession of the
Property, Tenant will at once surrender and deliver up the Property, together
with all improvements thereon, to Landlord, broom clean1 in good order,
condition and repair, ordinary wear and tear excepted. "Broom clean" means free
from all debris, dirt, rubbish, personal property of Tenant, oil, grease, tire
tracks or other substances, inside and outside of the building and on the
grounds comprising the Property. Any damage caused by removal of Tenant from the
Property, including any damages caused by removal of Tenant's equipment as
herein defined, shall be repaired by Tenant at its cost prior to the expiration
of this Lease term. In the event any improvements or Tenant's equipment are not
removed by Tenant at the time of the expiration' of this Lease tern,, Tenant
shall pay rent until such improvements and fixtures and Tenant's equipment are
removed.

         All additions, hardware, improvements, temporary or permanent, in or
upon the Property placed there by Tenant will become Landlord's property and
shall remain upon the Property upon such termination of this Lease by lapse of
time or otherwise, without compensation or allowance or credit to Tenant, unless
Landlord requests their removal. If Landlord so requests removal of such
additions, hardware, or improvements and Tenant does make such removal by the
termination of this Lease, or within ten (10) days after such request, whichever
is later, Landlord may remove the same and deliver the same to any other place
business of Tenant or warehouse the same, and Tenant agrees to pay the cost of
such removal, delivery and warehousing to Landlord on demand.

         24.2     HOLDING OVER.

         Any holding over by Tenant of the Property after the expiration or
sooner termination of this Lease shall operate and be construed to be a tenancy
from month to month only, at [...***...]% of the most recent monthly rate of
rent and other charges payable for the Lease term. If any holding over extends
for at least six (6) months, then, at the election of Landlord expressed in a
written notice to Tenant, and not otherwise, such holding over shall constitute
a renewal of this Lease for one (1) year at [...***...]% of the most recent
Fixed Annual Rent and upon all of the other covenants and agreements contained
in this Lease, provided, however, that if Tenant quits and fully vacates the
Property within ten (10) days following such Landlord's notice then no such one
year renewal will be created, and Tenant will be liable for the month-to-month
tenancy rent set forth above. If Tenant continues to hold over after a written
demand by Landlord for possession at the expiration of this Lease or after
termination by either party of a month-to-month tenancy created pursuant to this
Section, or after termination of the Lease or of Tenant's




                                     26.
                                          * Confidential Treatment Requested
<Page>


right to possession pursuant to any other section, Tenant shall pay monthly
rent at a rate equal to [...***...]% of rent payable immediately prior to the
expiration or other termination of the Lease or Tenant's right to possession.
Nothing contained in this Section 24.2 should be construed to give Tenant the
right to hold over at any time, and Landlord may exercise any and all
remedies at law or in equity to recover possession of the Property, as well
as any damages incurred by Landlord due to Tenant's failure to vacate the
Property and deliver possession to Landlord as herein provided.

25.      COVENANT OF QUIET ENJOYMENT

         25.1     QUIET ENJOYMENT.

         Subject to Section 14.1, Landlord covenants and represents that
Landlord has full right and power to execute and perform this Lease and to grant
the demised estate; and that at all times when Tenant is not in default under
the terms of and during the term of this Lease, Tenant's quiet and peaceable
enjoyment of the Property shall not be disturbed or interfered with by Landlord
or by any person claiming by, through or under Landlord.

         25.2     CONTROL OF PROPERTY.

         Tenant, during the term of this Lease and any extensions, is entitled
to have exclusive control of the Property, and neither Landlord nor any
mortgagee of Landlord may take any action pertaining to the Property without the
prior written consent of Tenant, except as otherwise specifically provided in
this Lease.


26.      BROKERAGE

         26.1     BROKERAGE.

         Tenant represents and warrants that it has had no dealings with any
broker or agent in connection with this Lease and Tenant covenants to pay, hold
harmless and indemnify each Indemnified Party from and against any and all cost,
expense or liability for any compensation, commissions and charges claimed by
any broker or other agent with respect to this Lease.


27.      RECORDING OF MEMORANDUM OF LEASE

         27.1     RECORDING.

         29.1     RUN WITH LAND.

         All of the covenants, agreements, conditions and undertakings in this
Lease extend and inure to and be binding upon the heirs, executors,
administrators, successors and assigns of the respective parties, the same as if
they were in every case specifically named, and are covenants running with the
land, and wherever in this Lease reference is made to either of the parties. It
shall be held to include and apply to, wherever applicable, the heirs,
executors, administrators, successors and assigns of such party. Nothing in this
Lease shall be construed to grant or confer upon any person or persons, firm,
corporation or governmental authority, other than the parties hereto, their
heirs, executors, administrators, successors and assigns, any right, claim or
privilege by virtue of any covenant, agreement, condition or undertaking in this
Lease contained.

         29.2     MEANING OF "LANDLORD".

         The term "Landlord" as used in this Lease, so far as covenants or
obligations on the part of landlord are concerned, means and includes only the
owner or owners at the time in question of the fee of the Property, and in the
event of any transfer or transfers of the title to such fee, the Landlord (and
in case of any subsequent transfers or conveyances, the then grantor) will be
automatically freed and relieved, from and after the date of such transfer or
conveyance, of all personal liability as respects the performance of any
covenants or obligations on the part of Landlord contained in this Lease to be
performed after the transfer or conveyance: provided that any funds in the hands
of such Landlord or the then grantor at the time of such transfer, in which
Tenant has an interest, must be turned over to the grantee, and any amount then
due


                                     28.
<Page>



and payable to Tenant by Landlord or the then grantor under any provisions of
this Lease, must be paid to Tenant.

         29.3     LIMITATION ON LANDLORD'S LIABILITY.

         If Landlord or any successors in interest is an individual, joint
venture, tenancy in common, firm or partnership, general or limited, there will
be no personal liability on such individual or on the members of such joint
venture, tenancy in common, firm, or partnership or on such joint venture,
tenancy in common, firm, or partnership, in respect to any of the covenants or
conditions of this Lease, and in the event of any default or breach by Landlord
with respect to any of the terms, covenants and of this Lease to be observed,
honored or performed by Landlord, Tenant agrees to look solely to the estate and
property of Landlord in the land and buildings owned by Landlord comprising
Property for the collection of any judgment (or any other judicial procedures,
requiring the payment of money by Landlord) and no other property or assets of
Landlord is subject to levy, execution, or other procedures for satisfaction of
Tenant's remedies. Nothing contained in this Section 29.3 is intended to or may
be used to limit the liability or responsibility of an insurance carrier from
paying on a claim otherwise payable under an insurance policy maintained by
Landlord.

                                GUARANTY OF LEASE


         This Guaranty of Lease (the "GUARANTY") is attached to and made part of
the Building Lease (the "LEASE") dated November 17, 2000 between BRADLEY

         1. GUARANTY. In consideration of the execution of the Lease by Landlord
and as a material inducement to Landlord to execute the Lease, Guarantor

         3. TENANT'S DEFAULT. This Guaranty is a guaranty of payment and
performance, and not of collection. Upon any Event of Default by Tenant as
defined under the Lease, Landlord may proceed immediately against Tenant and/or
Guarantor to enforce any of Landlord's rights or remedies against Tenant or

limitations as to Guarantor.

         5. SEPARATE AND DISTINCT OBLIGATIONS. Guarantor acknowledges and agrees
that Guarantor's obligations to Landlord under this Guaranty are separate and
distinct from Tenant's obligations to Landlord under the Lease. The occurrence
of any of the following events will not have any effect whatsoever on any
Guarantor's obligations to Landlord under this Guaranty, each of which
obligations continues in full force or effect as though such event had not
occurred: (a) the commencement by Tenant of a voluntary case under the federal
bankruptcy laws, as now constituted or hereafter amended or replaced, or any
other applicable federal or state bankruptcy, insolvency or other similar law
(collectively, the "BANKRUPTCY LAWS"), (b) the consent by Tenant to the
appointment of or taking possession by a receiver, liquidator, assignee,
trustee, custodian or similar official of Tenant or of any substantial part of
its property, (c) any assignment by Tenant for the benefit of creditors, (d) the
failure of Tenant generally to pay its debts as such debts become due, (e) the
taking of a corporate action by Tenant in the furtherance of any of the
foregoing; or (f) the entry of a decree or order for relief by a court having
jurisdiction in respect of Tenant in any involuntary case under the Bankruptcy
Laws, or appointing a receiver, liquidator, assignee, custodian, trustee (or
similar official) of Tenant or of any substantial part of its property, or
ordering the winding-up or liquidation of any of its affairs and the continuance
of any such decree or order unstayed and in effect for a period of sixty (60)
consecutive days. The liability of Guarantor under this Guaranty is not and will
not be affected or impaired by any payment made to Landlord under or related to
the Lease for which Landlord is required to reimburse Tenant pursuant to any
court order or in settlement of any dispute, controversy or litigation in any
bankruptcy, reorganization, arrangement, moratorium or other federal or state
debtor relief proceeding. If, during any such proceeding, the Lease is assumed
by Tenant or any trustee, or thereafter assigned by Tenant or any trustee to a
third party, this Guaranty will remain in full force and effect with respect to
the full performance of Tenant, any such trustee or any such third party's
obligations under the Lease. If the Lease is terminated or rejected during any
such proceeding, or if any of the events described in Subparagraphs (a) through
(f) of this Paragraph 5 occur, as between Landlord and Guarantor, Landlord will
have the right to accelerate all of Tenant's obligations under the Lease and
each Guarantor's obligations under this Guaranty. In such event, all such
obligations will become immediately due and payable by Guarantors to Landlord.
Guarantor waives any defense arising by reason of any disability or other
defense of Tenant or by reason of the cessation for any cause whatsoever of the
liability of Tenant.

         6. SUCCESSORS AND ASSIGNS. This Guaranty binds Guarantor and its
successors and assigns.


                                      2.
<Page>


         7. ENCUMBRANCES. If Landlord's interest in the Building, the Property,
the Lease or the rents, issues or profits, are subject to any deed of trust,
mortgage or assignment for security, any Guarantor's acquisition of Landlord's
interest in the Property or Lease will not affect any of Guarantor's obligations
under this Guaranty. In such event, this Guaranty will nevertheless continue in
full force and effect for the benefit of any mortgagee, beneficiary, trustee or
assignee or any purchase at any sale by judicial foreclosure or under any
private power of sale, and their successors and assigns.

         8. GUARANTOR'S DUTY. Guarantor acknowledges that it is aware of the
present financial condition of Tenant. Guarantor assumes the responsibility to
remain informed of the financial condition of Tenant and of all other
circumstances bearing upon the risk of Tenant's default, which reasonable
inquiry would reveal, and agree that Landlord has no duty to advise Guarantor of
information known to it regarding such condition or any such circumstance.

         9. LANDLORD'S RELIANCE. Landlord is not required to inquire into the
powers of Tenant or the officers, employees, partners or agents acting or
purporting to act on its behalf, and any indebtedness made or created in
reliance upon the professed exercise of such powers will be guaranteed under
this Guaranty.
