     Section 1.02   LEASE OF PREMISES. Landlord hereby leases to Tenant and
Tenant hereby leases from Landlord the Leased Premises, under the terms and
conditions herein, together with a non-exclusive right, in common with others,
to use the following (collectively, the "Common Areas"): the areas of the
Building and the underlying land and improvements thereto that are designed for
use in common by all tenants of the Building and their respective employees,
agents, customers, invitees and others.

                          ARTICLE 2  TERM AND POSSESSION

     Section 2.01   TERM. The Commencement Date and Lease Term shall be as set
forth in Sections 1.01(f) and 1.01(g) above.

     Section 2.02   EXTENSION TERM.

     (a)  Tenant shall have the right, but not the obligation, to extend the
Term of this Lease for one (1) additional period of three (3) consecutive years
(the "Extension Term"); provided, (i) Tenant

                                      - 2 -
<Page>

gives written notice of each election no earlier than fourteen (14) months and
no later than nine (9) months prior to the proposed commencement of the
Extension Term ("Tenant's Extension Notice"), and (ii) no Event of Default on
the part of Tenant has occurred and then remains uncured under this Lease.

     (b)  If Tenant validly exercises its right to extend the Term of this Lease
for the Extension Term, Minimum Annual Rent shall be equal to the then-current
"Fair Market Rent" for the Leased Premises.

     (c)  "Fair Market Rent" means a new Minimum Annual Rental determined for
occupancy commencing as of the first day of the Extension Term as reasonably
determined by Landlord (and adjusted as described herein), taking into
consideration the rental rates then being quoted by Landlord and other landlords
for similar space in similar buildings in the area. Landlord's determination of
the Fair Market Rent shall be stated in Landlord's notice to Tenant given within
thirty (30) days after Landlord's receipt of Tenant's Extension Notice.
Landlord's determination of Fair Market Rent shall be final and binding, unless
Tenant notifies Landlord in writing within ten (10) business days after receipt
of Landlord's notice that it disagrees with Landlord's determination of the Fair
Market Rent. If the parties are unable to agree on the Fair Market Rent to be
paid by Tenant after negotiating in good faith for ten (10) business days
thereafter, then each party shall select one (1) appraiser who shall be a member
of the American Institute of Real Estate Appraisers within ten (10) days after
the parties shall fail to reach agreement (and if either party fails to make a
selection within that period, the right to do so shall be deemed waived), and
the two (2) appraisers shall then select a third (3rd) appraiser, again within a
ten (10) day period, to comprise an appraiser panel. The panel shall then
determine, within twenty (20) days after the selection of the third (3rd)
appraiser, the then Fair Market Rent. In the event the appraisers are unable to
agree upon the Fair Market Rent, the Fair Market Rent shall equal the average of
the two (2) appraisals closest in amount. Each party shall pay the cost of its
own appraiser and divide evenly the cost of the third (3rd) appraiser.

     Section 2.03   CONDITION OF THE LEASED PREMISES; LANDLORD PRE-OCCUPANCY
COVENANTS.

     (a)  AS IS CONDITION. Tenant has personally inspected the Leased Premises
and accepts the same "AS IS" without representation or warranty by Landlord of
any kind; provided that Landlord represents and warrants that to the best of its
knowledge the Building, including without limitation it's roof and structure,
walls, foundation and all systems (including heating, air conditioning and
ventilation, sprinkler systems, plumbing and electrical), Leased Premises,
Common Areas and the Property (as defined below) are in good condition and
repair.

     (b)  CONSTRUCTION OF TENANT IMPROVEMENTS. Tenant shall construct and
install all leasehold improvements to the Leased Premises (collectively, the
"Tenant Improvements") in accordance with EXHIBIT B attached hereto and made a
part hereof.

     (c)  LANDLORD COVENANTS. Prior to the Commencement Date Landlord shall
construct and install a demising wall  and related improvements for the Leased
Premises as described in EXHIBIT C and repaint the "office" areas of the Leased
Premises.

     Section 2.04   SURRENDER OF THE PREMISES. Upon the expiration or earlier
termination of this Lease, Tenant shall, at its sole cost and expense,
immediately (a) surrender the Leased Premises to Landlord in broom-clean
condition and in good order, condition and repair, (b) remove from the Leased
Premises (i) Tenant's Property (as defined in Section 8.01 below), (ii) all data
and communications wiring and cabling (including above ceiling, below raised
floors and behind walls) added by Tenant, and (iii) any alterations required to
be removed pursuant to Section 7.03 below, and (c) repair any damage caused by
any such removal and restore the Leased Premises to the condition existing upon
the Commencement Date, reasonable wear and tear excepted (subject to any interim
casualty, or condemnation). All of Tenant's Property that is not removed within
ten (10) days following Landlord's written demand therefor shall be conclusively
deemed to have been abandoned and Landlord shall be entitled to dispose of such
property at Tenant's cost without incurring any liability to Tenant. This
Section 2.03 shall survive the expiration or any earlier termination of this
Lease.

     Section 2.05   HOLDING OVER. If Tenant retains possession of the Leased
Premises after the expiration or earlier termination of this Lease, Tenant shall
be a tenant at sufferance at one hundred fifty percent (150%) of the Monthly
Rental Installments and Annual Rental Adjustment (as hereinafter defined) for
the Leased Premises in effect upon the date of such expiration or earlier
termination, and otherwise upon the terms, covenants and conditions herein
specified, so far as applicable. Acceptance by Landlord of rent after such
expiration or earlier termination shall not result in a renewal of this Lease,
nor shall such acceptance create a month-to-month tenancy. In the event a
month-to-month tenancy is created by operation of law, or by written agreement
of the parties, either party shall have the right to terminate such
month-to-month tenancy upon thirty (30) days' prior written notice to the other,
whether or not said notice is given on the rent paying date. This Section 2.05
shall in no way constitute a consent by Landlord to any holding over by Tenant
upon the expiration or earlier termination of this Lease, nor limit Landlord's
remedies in such event.

     Section 3.01   BASE RENT. Tenant shall pay to Landlord the Minimum Annual

product of Tenant's Proportionate Share times the Insurance Premiums.

utility costs, or (3) incurred to replace existing equipment and machinery

portion shall be included in Operating Expenses;

     Section 3.03   PAYMENT OF ADDITIONAL RENT.

     (a)  Any amount required to be paid by Tenant hereunder (in addition to
Minimum Annual Rent) and any charges or expenses incurred by Landlord on behalf
of Tenant under the terms of this Lease shall be considered "Additional Rent"
payable in the same manner and upon the same terms and conditions as the Minimum
Annual Rent reserved hereunder, except as set forth herein to the contrary. Any
failure on the part of Tenant to pay such Additional Rent when and as the same
shall become due shall entitle Landlord to the remedies available to it for
non-payment of Minimum Annual Rent.

     (b)  In addition to the Minimum Annual Rent specified in this Lease,
commencing as of the Commencement Date, Tenant shall pay to Landlord as
Additional Rent for the Leased Premises, in each

                                      - 7 -
<Page>

calendar year or partial calendar year during the Lease Term, an amount equal to
the Annual Rental Adjustment for such calendar year. Landlord shall estimate the
Annual Rental Adjustment annually, and written notice thereof shall be given to
Tenant prior to the beginning of each calendar year. Tenant shall pay to
Landlord each month, at the same time the Monthly Rental Installment is due, an
amount equal to one-twelfth (1/12) of the estimated Annual Rental Adjustment.
Tenant shall be responsible for delivering the Additional Rent to the payment
address set forth in Section 1.01(k) above in accordance with this Section 3.03.
If Operating Expenses increase during a calendar year, Landlord may increase the
estimated Annual Rental Adjustment during such year by giving Tenant written
notice to that effect, and thereafter Tenant shall pay to Landlord, in each of
the remaining months of such year, an amount equal to the amount of such
increase in the estimated Annual Rental Adjustment divided by the number of
months remaining in such year. Within a reasonable time after the end of each
calendar year, Landlord shall prepare and deliver to Tenant a statement showing
the actual Annual Rental Adjustment. Within thirty (30) days after receipt of
the aforementioned statement, Tenant shall pay to Landlord, or Landlord shall
credit against the next rent payment or payments due from Tenant (or refund if
the Lease Term has expired), as the case may be, the difference between the
actual Annual Rental Adjustment for the preceding calendar year and the
estimated amount paid by Tenant during such year.

     (c)  Upon Tenant's reasonable notice, given within ninety (90) days after
Tenant's receipt of Landlord's statement for any calendar year during the Lease
Term, Landlord shall make available for Tenant's and/or Tenant's agents'
inspection and photocopying, during normal business hours, Landlord's records
relating to Landlord's Operating Expenses for the period covered by any invoice
or annual statement. If Tenant has not timely notified Landlord of Tenant's
desire to inspect, Tenant shall be deemed to be satisfied with that statement
from Landlord and the amounts Tenant is obligated to pay pursuant thereto.
Should Tenant dispute any of Landlord's Operating Expenses, Tenant shall be
entitled to audit Landlord's Operating Cost records for the calendar year in
question. Should the audit determine that Tenant was over-charged, then,
Landlord shall credit Tenant the amount of such over-charge toward the payments
of Minimum Annual Rent and Additional Rent next coming due under the Lease;
provided that if the Lease Term has expired, Landlord shall pay such amount to
Tenant within thirty (30) days of invoice. Should the audit determine that
Tenant has been under-charged, Tenant shall reimburse Landlord for such amount
as Additional Rent next coming due under the Lease. Tenant agrees to pay the
actual, reasonable, out-of-pocket cost of the audit, unless the audit determines
that Landlord's calculation of Landlord's Operating Expenses was overstated by
more than five percent (5%), in which case Landlord shall pay for the audit.

     Section 3.04   LATE CHARGES. Tenant acknowledges that Landlord shall incur
certain additional unanticipated administrative and legal costs and expenses if
Tenant fails to pay timely any payment required hereunder. Therefore, without
exercising any late payment or limiting Landlord's rights and remedies under
this Lease, Tenant shall pay Landlord, upon demand, a late charge of 5% of any
payment not made within five (5) days of its due date. In addition to such late
charge and the other remedies available to Landlord hereunder, if any payment
required to be paid by Tenant to Landlord hereunder shall become overdue, such
unpaid amount shall bear interest from the due date thereof to the date of
payment at the lesser of the prime rate of interest, as reported in the Wall
Street Journal (the "Prime Rate") plus three percent (3%) per annum and the
maximum legal rate of interest.

                           ARTICLE 4  SECURITY DEPOSIT

     Upon execution and delivery of this Lease by Tenant, Tenant shall deposit
the Security Deposit with Landlord as security for the performance by Tenant of
all of Tenant's obligations contained in this Lease. In

                                      - 8 -
<Page>

the event of a Default by Tenant, Landlord may at its option apply all or any
part of the Security Deposit to cure all or any part of such Default; provided,
however, that any such application by Landlord shall not be or be deemed to be
an election of remedies by Landlord or considered or deemed to be liquidated
damages. If so applied by Landlord, Tenant agrees promptly, upon demand, to
deposit such additional sum with Landlord as may be required to maintain the
full amount of the Security Deposit. All sums held by Landlord pursuant to this
Article 4 shall be without interest and may be commingled by Landlord. Promptly
after the end of the Lease Term, provided that there is then no uncured Default
or any repairs required to be made by Tenant pursuant to Section 2.03 above or
Section 7.03 below, Landlord shall return the Security Deposit to Tenant.

                           ARTICLE 5  OCCUPANCY AND USE

     Section 5.01   USE. Tenant shall use the Leased Premises for the Permitted
Use and for no other purpose without the prior written consent of Landlord.

     Section 5.02   COVENANTS OF TENANT REGARDING USE.

     (a)  Tenant shall (i) use and maintain the Leased Premises and conduct its
business thereon in a safe, careful and lawful manner, (ii) comply with all
laws, rules, regulations, orders, ordinances, directions and requirements of any
governmental authority or agency, now in force or which may hereafter be in
force, including, without limitation, those which shall impose upon Landlord or
Tenant any duty with respect to or triggered by a change in the use or
occupation of, Tenant's particular use or occupancy of, or any improvement or
alteration to, the Leased Premises, and (iii) comply with and obey all
reasonable directions, rules and regulations of Landlord, including without
limitation the Building Rules and Regulations attached hereto as EXHIBIT E and
made a part hereof, as may be modified from time to time by Landlord on
reasonable notice to Tenant, provided that that such rules and regulations do
not unreasonably interfere with Tenant's use and enjoyment of the Leased
Premises for the Permitted Use. Landlord represents that Landlord has not
received any notices of non-compliance with respect to any laws affecting the
Leased Premises, the Building or the Common Areas. Notwithstanding the
foregoing, Tenant shall have no obligation to correct any noncompliance of the
Premises with applicable laws existing as of the Commencement Date.

     (b)  Tenant shall not do or permit anything to be done in or about the
Leased Premises that will in any way cause a nuisance, obstruct or interfere
with the rights of other tenants or occupants of the Building or injure them.
Landlord shall not be responsible to Tenant for the non-performance by any other
tenant or occupant of the Building of any of Landlord's directions, rules and
regulations, but agrees that any enforcement thereof shall be done uniformly.
Tenant shall not overload the floors of the Leased Premises. All damage to the
floor structure or foundation of the Building due to improper positioning or
storage of items or materials shall be repaired by Landlord at the sole expense
of Tenant, who shall reimburse Landlord immediately therefor upon demand. Tenant
shall not use the Leased Premises, nor allow the Leased Premises to be used, for
any purpose or in any manner that would (i) invalidate any policy of insurance
now or hereafter carried by Landlord on the Building, or (ii) increase the rate
of premiums payable on any such insurance policy unless Tenant reimburses
Landlord for any increase in premium charged.

     (c)  Tenant shall complete a Tenant Operations Inquiry Form in
substantially the form of EXHIBIT D attached hereto and made a part hereof.

     Section 5.03   LANDLORD'S RIGHTS REGARDING USE. Without limiting any of
Landlord's rights specified elsewhere in this Lease (a) Landlord shall have the
right at any time, without notice to Tenant, to control, change or otherwise
alter the Common Areas in such manner as it deems necessary or proper and does
not interfere with the permitted use of the Lease Premises, and (b) Landlord,
its agents, employees and contractors and any mortgagee of the Building shall
have the right to enter any part of the Leased Premises at reasonable times upon
reasonable notice (except in the event of an emergency where no notice shall be
required) for the purposes of examining or inspecting the same (including,
without limitation, testing to confirm Tenant's compliance with this Lease),
showing the same to prospective purchasers, mortgagees or tenants, and making
such repairs, alterations or improvements to the Leased Premises or the Building
as Landlord may deem necessary or desirable. Landlord shall incur no liability
to Tenant for such entry, nor shall such entry constitute an actual or
constructive eviction of Tenant or a termination of this Lease, or entitle
Tenant to any abatement of rent therefor.

                               ARTICLE 6  UTILITIES

     Tenant shall obtain in its own name and pay directly to the appropriate
supplier the cost of all utilities and services serving the Leased Premises.
However, if any services or utilities are jointly metered with other property,
Landlord shall make a reasonable determination of Tenant's proportionate share
of the cost of such utilities and services (at rates that would have been
payable if such utilities and services had been directly billed by the utilities
or services providers without mark-up by Landlord) and Tenant shall pay such
share to Landlord within fifteen (15) days after receipt of Landlord's written
statement. Landlord shall not be liable in damages or otherwise for any failure
or interruption of any utility or other Building service and no such failure or
interruption shall entitle Tenant to terminate this Lease or withhold sums due
hereunder or constitute an actual or constructive eviction of Tenant.

                 ARTICLE 7  REPAIRS, MAINTENANCE AND ALTERATIONS

     Section 7.01   REPAIR AND MAINTENANCE OF BUILDING. Landlord shall make all
necessary repairs, replacements and maintenance to the roof, sprinkler systems,
exterior walls, foundation, structural frame of the Building, any electrical
systems, heating and air conditioning and plumbing systems and the parking
(including snow plowing) and landscaped areas and other Common Areas. The cost
of such repairs, replacements and maintenance shall be included in Operating
Expenses to the extent provided in Section 3.02; provided however, to the extent
any such repairs, replacements or maintenance are required because of the
negligence, misuse or Default of Tenant, its employees, agents, contractors,
customers or invitees, Landlord shall make such repairs at Tenant's sole
expense.

     Section 7.02   REPAIR AND MAINTENANCE OF LEASED PREMISES. Tenant shall, at
its own cost and expense, maintain the Leased Premises in good condition,
regularly servicing and promptly making all repairs thereto, including but not
limited to plate glass, floors, windows and doors, dock-doors, levelers, and
trash compactors and shall be responsible for janitorial and pest control
services.

     Section 7.03   ALTERATIONS. Tenant shall not permit alterations in or to
the Leased Premises unless and until Landlord has approved the plans therefor in
writing. If Landlord has notified Tenant in writing at the time of an
alteration, Landlord may require Tenant to remove the alterations and restore
the Leased Premises upon termination of this Lease; otherwise, all such
alterations shall become a part of the realty and the property of Landlord, and
shall not be removed by Tenant. Tenant shall ensure that all alterations shall
be made in accordance with all applicable laws, regulations and building codes,
in a good

                                     - 10 -

and workmanlike manner and of quality equal to or better than the original
construction of the Building. No person shall be entitled to any lien derived
through or under Tenant for any labor or material furnished to the Leased
Premises, and nothing in this Lease shall be construed to constitute Landlord's
consent to the creation of any lien. If any lien is filed against the Leased
Premises for work claimed to have been done for or material claimed to have been
furnished to Tenant, Tenant shall cause such lien to be discharged of record
within thirty (30) days after filing. Tenant shall indemnify Landlord from all
costs, losses, expenses and attorneys' fees in connection with any construction
or alteration and any related lien.

                        ARTICLE 8  INDEMNITY AND INSURANCE

     Section 8.01   RELEASE. All of Tenant's trade fixtures, merchandise,
inventory and all other personal property in or about the Leased Premises, the

liable to Tenant or to any other person for, and Tenant hereby releases Landlord
from (a) any and all liability for theft or damage to Tenant's Property, and (b)
any and all liability for any injury to Tenant or its employees, agents,
contractors, guests and invitees in or about the Leased Premises, the Building

loss or damage) caused directly by the negligence or willful misconduct of
Landlord, its agents, employees or contractors. Nothing contained in this
Section 8.01 shall limit (or be deemed to limit) the waivers contained in
Section 8.06 below. In the event of any conflict between the provisions of
Section 8.06 below and this Section 8.01, the provisions of Section 8.06 shall
prevail. This Section 8.01 shall survive the expiration or earlier termination
of this Lease.

     Section 8.02   INDEMNIFICATION BY TENANT. Tenant shall protect, defend,
indemnify and hold Landlord, its agents, employees and contractors harmless from
and against any and all claims, damages, demands, penalties, costs, liabilities,
losses, and expenses (including without limitation reasonable attorneys' fees
and expenses at the trial and appellate levels) to the extent (a) arising out of
or relating to any act, omission, negligence, or willful misconduct of Tenant or
Tenant's agents, employees, contractors, customers or invitees in or about the
Leased Premises, the Building or the Common Areas, (b) arising out of or
relating to any of Tenant's Property, or (c) arising out of any other act or
occurrence within the Leased Premises, in all such cases except to the extent of
personal injury (but not property loss or damage) caused directly by the
negligence or willful misconduct of Landlord, its agents, employees or
contractors. Nothing contained in this Section 8.02 shall limit (or be deemed to
limit) the waivers contained in Section 8.06 below. In the event of any conflict
between the provisions of Section 8.06 below and this Section 8.02, the
provisions of Section 8.06 shall prevail. This Section 8.02 shall survive the
expiration or earlier termination of this Lease.

     Section 8.03   INDEMNIFICATION BY LANDLORD. Landlord shall protect, defend,
indemnify and hold Tenant, its agents, employees and contractors harmless from
and against any and all claims, damages, demands, penalties, costs, liabilities,
losses and expenses (including without limitation reasonable attorneys' fees and
expenses at the trial and appellate levels) to the extent arising out of or
relating to negligence or willful misconduct of Landlord or Landlord's agents,
employees or contractors. Nothing contained in this Section 8.03 shall limit (or
be deemed to limit) the waivers contained in Section 8.06 below. In the event of
any conflict between the provisions of Section 8.06 below and this Section 8.03,

                                     - 11 -
<Page>

the provisions of Section 8.06 shall prevail. This Section 8.03 shall survive
the expiration or earlier termination of this Lease.

     Section 8.04   TENANT'S INSURANCE. Tenant shall purchase, at its own
expense, and keep in force at all times during the Lease Term the policies of
insurance set forth below (collectively, "Tenant's Policies"). All Tenant's
Policies shall (a) be issued by an insurance company with a Best's rating of A-
or better and otherwise reasonably acceptable to Landlord and shall be licensed
to do business in the state in which the Leased Premises is located; (b) provide
that said insurance shall not be canceled or materially modified unless 30 days'
prior written notice shall have been given to Landlord; (c) provide for
deductible amounts that are reasonably acceptable to Landlord (and its lender,
if applicable) and (d) otherwise be in such form, and include such coverages, as
Landlord may reasonably require. The Tenant's Policies described in (i) and (ii)
below shall (1) provide coverage on an occurrence basis; (2) name Landlord (and
its lender, if applicable) as additional insured; (3) provide coverage, to the
extent insurable, for the indemnity obligations of Tenant under this Lease; (4)
contain a separation of insured parties provision; (5) be primary, not
contributing with, and not in excess of, coverage that Landlord may carry; and
(6) provide coverage with no exclusion for a pollution incident arising from a
hostile fire. All Tenant's Policies (or, at Landlord's option, Certificates of
Insurance and applicable endorsements, including, without limitation, an
"Additional Insured-Managers or Landlords of Premises" endorsement) shall be
delivered to Landlord prior to the Commencement Date and renewals thereof shall
be delivered to Landlord's notice addresses at least 30 days prior to the
applicable expiration date of each Tenant's Policy. In the event that Tenant
fails, at any time or from time to time, to comply with the requirements of the
preceding sentence and such failure continues for 10 days following written
notice thereof from Landlord, Landlord may (A) order such insurance and charge
the cost thereof to Tenant, which amount shall be payable by Tenant to Landlord
upon demand, as Additional Rent or (B) impose on Tenant, as Additional Rent, a
monthly delinquency fee, for each month during which Tenant fails to comply with
the foregoing obligation, in an amount equal to five percent (5%) of the Monthly
Rental Installments then in effect. Tenant shall give prompt notice to Landlord
and Agent of any bodily injury, death, personal injury, advertising injury or
property damage occurring in and about the Property.

     Tenant shall purchase and maintain, throughout the Term, a Tenant's
Policy(ies) of: (i) commercial general or excess liability insurance, including
personal injury and property damage, in the amount of not less than
$2,000,000.00 per occurrence, and $5,000,000.00 annual general aggregate, per
location; (ii) comprehensive automobile liability insurance covering Tenant
against any personal injuries or deaths of persons and property damage based
upon or arising out of the ownership, use, occupancy or maintenance of a motor
vehicle at the Leased Premises and all areas appurtenant thereto in the amount
of not less than $1,000,000, combined single limit; (iii) commercial property
insurance covering Tenant's Property (at its full replacement cost); (iv)
workers' compensation insurance per the applicable state statutes covering all
employees of Tenant; (v) business interruption insurance with limits not less
than an amount equal to one (1) year's rent due hereunder; and if Tenant
handles, stores or utilizes Hazardous Substances in its business operations
(other than customary office and manufacturing products), (vi) pollution legal
liability insurance.

     Section 8.05   LANDLORD'S INSURANCE. During the Lease Term, Landlord shall
maintain the following types of insurance (the cost of which shall be included
in Operating Expenses): (a) a commercial property insurance policy covering the
Building (at its full replacement cost), but excluding Tenant's personal
property and any improvements or alterations made by Tenant; (b) commercial
general public liability insurance covering Landlord for claims arising out of
liability for bodily injury, death, personal injury, advertising injury and
property damage occurring in and about the Building and otherwise resulting from
any acts or omissions of Landlord, its agents and employees; (c) rent loss
insurance; and (d) any other insurance coverage deemed appropriate by Landlord
or required by Landlord's lender. All of the coverages described in (a) through
(d) shall be determined from time to

                                     - 12 -
<Page>

time by Landlord, in its sole discretion. All insurance maintained by Landlord
shall be in addition to and not in lieu of the insurance required to be
maintained by the Tenant.

     Section 8.06   WAIVER OF SUBROGATION. Notwithstanding anything contained in
this Lease to the contrary, Landlord and Tenant hereby waive any rights each may
have against the other on account of any loss of or damage to their respective
property, the Leased Premises, its contents, or other portions of the Building
or Common Areas arising from any risk which is covered or required to be covered
by the insurance maintained by the waiving party pursuant to this Lease. The
special form coverage insurance policies maintained by Landlord and Tenant as
provided in this Lease shall include an endorsement containing an express waiver
of any rights of subrogation by the insurance company against Landlord and
Tenant, as applicable.

                               ARTICLE 9  CASUALTY

     In the event of total or partial destruction of the Building or the Leased
Premises by fire or other casualty, Landlord agrees promptly to restore and
repair same; provided, however, Landlord's obligation hereunder with respect to
the Leased Premises shall be limited to the reconstruction of such of the
leasehold improvements as were originally in place at the time of the
Commencement Date or required to be made by Landlord pursuant to Section 2.02
above, if any. Rent shall proportionately abate during the time that the Leased
Premises or part thereof are unusable because of any such damage.
Notwithstanding the foregoing, if the Leased Premises are (a) so destroyed that
they cannot be repaired or rebuilt within two hundred ten (210) days from the
casualty date; or (b) destroyed by a casualty that is not covered by the
insurance required hereunder or, if covered, such insurance proceeds are not
released by any mortgagee entitled thereto or are insufficient to rebuild the
Building and the Leased Premises; then, in case of a clause (a) casualty, either
Landlord or Tenant may, or, in the case in the case of a clause (b) casualty,
then Landlord may, upon thirty (30) days' written notice to the other party,
terminate this Lease with respect to matters thereafter accruing. Tenant waives
any right under applicable laws inconsistent with the terms of this paragraph.

     Notwithstanding anything in this Lease to the contrary, if (i) the Leased
Premises is damaged or destroyed during the last twelve (12) months of the Term;
or (ii) Landlord fails to substantially complete its repair or restoration
obligations within two hundred ten (210) days following the date of such
casualty, then Tenant may terminate the Lease by delivering written notice to
Landlord of its election to terminate within thirty (30) days after the casualty
with respect to (i) above, or, with respect to (ii) above, at any time after the
expiration of the applicable time period giving rise to Tenant's right to
terminate, provided, that Tenant's notice of termination shall be deemed null
and void if Landlord substantially completes the Leased Premises within sixty
(60) days following receipt of Tenant's termination notice.

                            ARTICLE 10  EMINENT DOMAIN

     If all or any substantial part of the Building or Common Areas shall be
acquired by the exercise of eminent domain, Landlord may terminate this Lease by
giving written notice to Tenant on or before the date possession thereof is so
taken. If all or any part of the Leased Premises shall be acquired by the
exercise of eminent domain so that the Leased Premises shall become impractical
for Tenant to use for the Permitted Use, Tenant may terminate this Lease by
giving written notice to Landlord as of the date possession thereof is so taken.
All damages awarded shall belong to Landlord; provided, however, that Tenant may
claim dislocation damages and the unamortized value or any leasehold
improvements.

                       ARTICLE 11  ASSIGNMENT AND SUBLEASE

     Section 11.01  ASSIGNMENT AND SUBLEASE.

     (a)  Tenant shall not assign this Lease or sublet the Leased Premises in
whole or in part without Landlord's prior written consent. In the event of any
assignment or subletting, Tenant shall remain primarily liable hereunder. In
addition, in the event of any assignment of the Lease or the subletting or more
than twenty percent (20%) of the rentable square feet of the Leased Premises,
any renewal, extension, expansion, rights of first offer, rights of first
refusal or other rights or options granted to Tenant under this Lease shall be
rendered void and of no further force or effect. The acceptance of rent from any
other person shall not be deemed to be a waiver of any of the provisions of this
Lease or to be a consent to the assignment of this Lease or the subletting of
the Leased Premises. Any assignment or sublease consented to by Landlord shall
not relieve Tenant (or its assignee) from obtaining Landlord's consent to any
subsequent assignment or sublease.

     (b)  By way of example and not limitation, Landlord shall be deemed to have
reasonably withheld consent to a proposed assignment or sublease if in
Landlord's opinion (i) the Leased Premises are or may be in any way adversely
affected; (ii) the business reputation of the proposed assignee or subtenant is
unacceptable; (iii) the financial worth of the proposed assignee or subtenant is
insufficient to meet the obligations hereunder, or (iv) the prospective assignee
or subtenant is a current tenant at the Building or is a bona-fide third-party
prospective tenant. Landlord further expressly reserves the right to refuse to
give its consent to any subletting if the proposed rent is advertised to the
general public (not including being offered and available through a broker of
Tenant) to be less than the then current rent for similar premises in the
Building.

     (c)  If Tenant shall make any assignment or sublease, with Landlord's
consent, for a rental in excess of the rent payable under this Lease after
deducting Tenant's reasonable out of pocket costs to procure and execute such
assignment or sublease, Tenant shall pay to Landlord fifty percent (50%) of any
such excess rental upon receipt. Tenant agrees to reimburse Landlord upon demand
for Landlord's reasonable accounting and attorneys' fees incurred in conjunction
with the processing and documentation of any requested assignment, subletting or
any other hypothecation of this Lease or Tenant's interest in and to the Leased
Premises, whether or not Landlord consents thereto.

     Section 11.02  PERMITTED TRANSFER. Notwithstanding anything to the contrary
contained in Section 11.01 above, Tenant shall have the right, without
Landlord's consent, but upon not less than ten (10) days' prior notice to
Landlord, to (a) sublet all or part of the Leased Premises to any related
corporation or other entity which controls Tenant, is controlled by Tenant or is
under common control with Tenant; (b) assign all or any part of this Lease to
any related corporation or other entity which controls Tenant, is controlled by
Tenant, or is under common control with Tenant, or to a successor entity into
which or with which Tenant is merged or consolidated or which acquires
substantially all of Tenant's stock, assets or property; or (c) effectuate any
public offering of Tenant's stock on the New York Stock Exchange or in the
NASDAQ over the counter market, provided that in the event of a transfer
pursuant to clause (b), the tangible net worth of Tenant's successor entity
after any such transaction (on a pro forma basis) is not less than the tangible
net worth of Tenant as of the date hereof and provided further that such
successor entity assumes all of the obligations and liabilities of Tenant (any
such entity hereinafter referred to as a "Permitted Transferee"). For the
purpose of this Article 11 (i) "control" shall mean

                                     - 14 -
<Page>

ownership of not less than fifty percent (50%) of all voting stock or legal and
equitable interest in such corporation or entity, and (ii) "tangible net worth"
shall mean the excess of the value of tangible assets (i.e. assets excluding
those which are intangible such as goodwill, patents and trademarks) over
liabilities. Any such transfer shall not relieve Tenant of its obligations under
this Lease. Nothing in this paragraph is intended to nor shall permit Tenant to
transfer its interest under this Lease as part of a fraud or subterfuge to
intentionally avoid its obligations under this Lease (for example, transferring
its interest to a shell corporation that subsequently files a bankruptcy), and
any such transfer shall constitute a Default hereunder. Any change in control of
Tenant resulting from a merger, consolidation, or a transfer of partnership or
membership interests, a stock transfer, or any sale of substantially all of the
assets of Tenant (other than as the result of transfers of any of Tenant's
publicly-traded stock) that do not meet the requirements of this Section 11.02
shall be deemed an assignment or transfer that requires Landlord's prior written
consent pursuant to Section 11.01 above.

                        ARTICLE 12  TRANSFERS BY LANDLORD

     Section 12.01  SALE OF THE BUILDING. Landlord shall have the right to sell
the Building at any time during the Lease Term, subject only to the rights of
Tenant hereunder; and such sale shall operate to release Landlord from liability
hereunder after the date of such conveyance.

     Section 12.02  ESTOPPEL CERTIFICATE. Within ten (10) days following receipt
of a written request from Landlord or Tenant, Tenant or Landlord, as applicable,
shall execute and deliver to the other party, without cost to the other party,
an estoppel certificate in such form as the other party may reasonably request
certifying (a) that this Lease is in full force and effect and unmodified or
stating the nature of any modification, (b) the date to which rent has been
paid, (c) that there are not, to the non-requesting party's knowledge, any
uncured Defaults or specifying such Defaults if any are claimed, and (d) any
other matters or state of facts reasonably required respecting the Lease. Such
estoppel may be relied upon by Tenant, Landlord and by any purchaser or
mortgagee of the Building or any party to a strategic transaction with Tenant.

     Section 12.03  SUBORDINATION. This Lease shall be automatically subordinate
to any mortgage, deed to secure debt, ground lease, deed of trust or other
instrument in the nature thereof, and any amendments or modifications thereto
(collectively, a "Mortgage") presently existing or hereafter encumbering the
Building without the need for any further act by any party. However, within ten
(10) days following receipt of a written request from Landlord, Tenant shall
execute and deliver to Landlord, without cost, any instrument that Landlord
deems reasonably necessary or desirable to confirm the subordination of this
Lease ; provided, however, that the subordination of this Lease to any mortgage
or ground lease entered into after the date of this Lease shall be upon the
express condition that so long as Tenant is not in default of the Lease beyond
applicable notice and cure periods, Tenant's possession and enjoyment of the
Leased Premises and Tenant's rights under the Lease shall not be disturbed or
interfered with in the event of a foreclosure of such Mortgage or the exercise
of any rights thereunder. Within 30 days of the execution of this Lease,
Landlord agrees to use reasonable efforts to obtain and deliver to Tenant a
subordination, non-disturbance and attornment agreement from its current lender
for the benefit of Tenant in a form reasonably acceptable to Tenant and such
lender.

<Page>

                          ARTICLE 13  DEFAULT AND REMEDY

     Section 13.01  DEFAULT.  The occurrence of any of the following shall be
a "Default":

     (a)  Tenant fails to pay any Monthly Rental Installments or Additional Rent
within five (5) days after Tenant has received written notice of the delinquent
payment from or on behalf of Landlord; provided, however, Landlord need not give
any such written notice for non-payment more than twice in any twelve (12) month
period; for the balance of such twelve (12) month period a Default shall have
occurred if a payment of any Base Rent is more than five (5) days past due, with
or without notice from Landlord.

     (b)  Tenant fails to perform or observe any other term, condition, covenant
or obligation required under this Lease for a period of thirty (30) days after
written notice thereof from Landlord; provided, however, that if the nature of
Tenant's Default is such that more than thirty (30) days are reasonably required
to cure, then Tenant shall have such additional time to cure such Default as is
reasonably necessary under the circumstances in question, provided that Tenant
commences such curative efforts as soon as is reasonably practical within said
thirty (30) day period and thereafter diligently completes the required action
within a reasonable time (not to exceed sixty (60) additional days).

     (c)  Tenant shall assign or sublet all or a portion of the Leased Premises
in contravention of the provisions of Article 11 of this Lease and the same is
not cured within thirty (30) days after written notice thereof from Landlord.

     (d)  All or substantially all of Tenant's assets in the Leased Premises or
Tenant's interest in this Lease are attached or levied under execution (and
Tenant does not discharge the same within sixty (60) days thereafter); a
petition in bankruptcy, insolvency or for reorganization or arrangement is filed
by or against Tenant (and Tenant fails to secure a stay or discharge thereof
within sixty (60) days thereafter); Tenant is insolvent and unable to pay its
debts as they become due; Tenant makes a general assignment for the benefit of
creditors; Tenant takes the benefit of any insolvency action or law; the
appointment of a receiver or trustee in bankruptcy for Tenant or its assets if
such receivership has not been vacated or set aside within sixty (60) days
thereafter; or, dissolution or other termination of Tenant's corporate charter
if Tenant is a corporation.

     In addition to the Defaults described above, the parties agree that if
Tenant receives written notice of the occurrence of any default above (but not
necessarily the same) three (3) or more times during any twelve (12) month
period, regardless of whether such defaults are ultimately cured, then such
conduct shall, at Landlord's option, represent a separate Default.

     Section 13.02  REMEDIES. Upon the occurrence of any Default , Landlord
shall have the following rights and remedies, in addition to those stated
elsewhere in this Lease and those allowed by law or in equity, any one or more
of which may be exercised without further notice to Tenant:

     (a)  Landlord may re-enter the Leased Premises and cure any Default of
Tenant, and Tenant shall reimburse Landlord as Additional Rent for any costs and
expenses which Landlord thereby incurs; and Landlord shall not be liable to
Tenant for any loss or damage which Tenant may sustain by reason of Landlord's
action.

                                     - 16 -
<Page>

     (b)  Without terminating this Lease, Landlord may terminate Tenant's right
to possession of the Leased Premises, and thereafter, neither Tenant nor any
person claiming under or through Tenant shall be entitled to possession of the
Leased Premises, and Tenant shall immediately surrender the Leased Premises to
Landlord, and Landlord may re-enter the Leased Premises and dispossess Tenant
and any other occupants of the Leased Premises by any lawful means and may
remove their effects, without prejudice to any other remedy that Landlord may
have. Upon termination of possession, Landlord may (i) re-let all or any part
thereof for a term different from that which would otherwise have constituted
the balance of the Lease Term and for rent and on terms and conditions different
from those contained herein, whereupon Tenant shall be immediately obligated to
pay to Landlord an amount equal to the present value (discounted at the Prime
Rate) of the difference between the rent provided for herein and that provided
for in any lease covering a subsequent re-letting of the Leased Premises, for
the period which would otherwise have constituted the balance of the Lease Term
(the "Accelerated Rent Difference"), or (ii) without re-letting, declare to be
immediately due and payable the difference between the present value (discounted
at the Prime Rate less 3%) of all rent which would have been due under this
Lease for the balance of the Lease Term to be immediately due and payable as
liquidated damages (the "Accelerated Rent") and the fair market rental value of
the Leased Premises for the same period of time (the "Fair Market Rental"), as
determined by an appraiser selected by Landlord, based upon recently completed
comparable lease transactions in the Building and the leasing submarket (the
Horsham, Montgomery County submarket) in which Leased Premises is located,
similarly discounted to present value (such difference being referred to as the
"Accelerated Fair Market Difference"). Upon termination of possession, Tenant
shall be obligated to pay to Landlord (A) the Accelerated Rent Difference or the
Accelerated Fair Market Difference, whichever is applicable, (B) all loss or
damage that Landlord may sustain by reason of Tenant's Default ("Default
Damages"), which shall include, without limitation, expenses of preparing the
Leased Premises for re-letting, demolition, repairs, tenant finish improvements,
brokers' commissions and attorneys' fees, and (C) all unpaid Minimum Annual Rent
and Additional Rent that accrued prior to the date of termination of possession,
plus any interest and late fees due hereunder (the "Prior Obligations").

     (c)  Landlord may terminate this Lease and declare the Accelerated Rent
Difference or the Accelerated Fair Market Difference, whichever is applicable,
to be immediately due and payable, whereupon Tenant shall be obligated to pay to
Landlord (i) the Accelerated Rent Difference or the Accelerated Fair Market
Difference, whichever is applicable, (ii) all of Landlord's Default Damages, and
(iii) all Prior Obligations. It is expressly agreed and understood that all of
Tenant's liabilities and obligations set forth in this subsection (c) shall
survive termination.

     (d)  Landlord and Tenant acknowledge and agree that the payment of the
Accelerated Rent Difference or the Accelerated Fair Market Difference as set
above shall not be deemed a penalty or forfeiture, but merely shall constitute
payment of liquidated damages, it being understood that actual damages to
Landlord are extremely difficult, if not impossible, to ascertain. Neither the
filing of a dispossessory proceeding nor an eviction of personalty in the Leased
Premises shall be deemed to terminate the Lease.

     (e)  Landlord may sue for injunctive relief or to recover damages for
any loss resulting from the Default.

     (f)  In addition to, and not in lieu of any of the foregoing rights
granted to Landlord:

TENANT HEREBY EMPOWERS ANY PROTHONOTARY, CLERK OF COURT OR ATTORNEY OF ANY COURT
OF RECORD TO APPEAR FOR TENANT IN ANY AND ALL ACTIONS WHICH MAY BE BROUGHT FOR
ANY RENT, OR ANY CHARGES HEREBY RESERVED OR DESIGNATED AS RENT OR ANY OTHER SUM
PAYABLE BY TENANT TO LANDLORD UNDER OR BY REASON OF THIS LEASE (INCLUDING,
WITHOUT LIMITATION, ANY SUM PAYABLE UNDER SECTION 13.2), AND TO SIGN FOR TENANT
AN AGREEMENT FOR ENTERING IN ANY COMPETENT COURT AN ACTION OR ACTIONS FOR THE
RECOVERY OF SAID RENT, CHARGES AND OTHER SUMS, AND IN SAID SUIT OR IN SAID
ACTION OR ACTIONS TO CONFESS JUDGMENT AGAINST TENANT FOR ALL OR ANY PART OF THE
RENT SPECIFIED IN THIS LEASE AND THEN UNPAID INCLUDING, AT LANDLORD'S OPTION,
THE RENT FOR THE ENTIRE UNEXPIRED BALANCE OF THE TERM OF THIS LEASE, AND ALL OR
ANY PART OF ANY OTHER OF SAID CHARGES OR SUMS, AND FOR INTEREST AND COSTS
TOGETHER WITH REASONABLE ATTORNEY'S FEES OF 5% OF SUCH SUMS. SUCH AUTHORITY
SHALL NOT BE EXHAUSTED BY ONE EXERCISE THEREOF, BUT JUDGMENT MAY BE CONFESSED AS
AFORESAID FROM TIME TO TIME AS OFTEN AS ANY OF SAID RENT OR SUCH OTHER SUMS,
CHARGES, PAYMENTS, COSTS AND EXPENSES SHALL FALL DUE OR BE IN ARREARS, AND SUCH
POWERS MAY BE EXERCISED AS WELL AFTER THE EXPIRATION OF THE TERM OR DURING ANY
EXTENSION OR RENEWAL OF THIS LEASE.

WHEN THIS LEASE OR TENANT'S RIGHT OF POSSESSION SHALL BE TERMINATED BY COVENANT
OR CONDITION BROKEN, OR FOR ANY OTHER REASON, EITHER DURING THE TERM OF THIS
LEASE OR ANY RENEWAL OR EXTENSION THEREOF, AND ALSO WHEN AND AS SOON AS THE TERM
HEREBY CREATED OR ANY EXTENSION THEREOF SHALL HAVE EXPIRED, IT SHALL BE LAWFUL
FOR ANY ATTORNEY AS ATTORNEY FOR TENANT TO FILE AN AGREEMENT FOR ENTERING IN ANY
COMPETENT COURT AN ACTION TO CONFESS JUDGMENT IN EJECTMENT AGAINST TENANT AND
ALL PERSONS CLAIMING UNDER TENANT, WHEREUPON, IF LANDLORD SO DESIRES, A WRIT OF
EXECUTION OR OF POSSESSION MAY ISSUE FORTHWITH, WITHOUT ANY PRIOR WRIT OF
PROCEEDINGS, WHATSOEVER, AND PROVIDED THAT IF FOR ANY REASON AFTER SUCH ACTION
SHALL HAVE BEEN COMMENCED THE SAME SHALL BE DETERMINED AND THE POSSESSION OF THE
LEASED PREMISES HEREBY DEMISED REMAIN IN OR BE RESTORED TO TENANT, LANDLORD
SHALL HAVE THE RIGHT UPON ANY SUBSEQUENT DEFAULT OR DEFAULTS, OR UPON THE
TERMINATION OF THIS LEASE AS HEREINBEFORE SET FORTH, TO BRING ONE OR MORE ACTION
OR ACTIONS AS HEREINBEFORE SET FORTH TO RECOVER POSSESSION OF THE SAID LEASED
PREMISES.

In any action to confess judgment in ejectment or for rent in arrears, Landlord
shall first cause to be filed in such action an affidavit made by it or someone
acting for it setting forth the facts necessary to authorize the entry of
judgment, of which facts such affidavit shall be conclusive evidence, and if a
true copy of this Lease (and of the truth of the copy such affidavit shall be
sufficient evidence) be filed in such action, it shall not be necessary to file
the original as a warrant of attorney, any rule of Court, custom or practice to
the contrary notwithstanding.

     Section 13.03  LANDLORD'S DEFAULT AND TENANT'S REMEDIES. Landlord shall be
in default if it fails to perform any term, condition, covenant or obligation
required under this Lease for a period of thirty (30) days after written notice
thereof from Tenant to Landlord; provided, however, that if the term, condition,
covenant or obligation to be performed by Landlord is such that it cannot
reasonably be performed within thirty (30) days, such default shall be deemed to
have been cured if Landlord commences such performance within said thirty-day
period and thereafter diligently undertakes to complete the same. Upon the
occurrence of any such default, Tenant may sue for injunctive relief or to
recover damages for

                                     - 18 -
<Page>

any loss directly resulting from the breach, but Tenant shall not be entitled to
terminate this Lease or withhold, offset or abate any sums due hereunder.

     Section 13.04  LIMITATION OF LANDLORD'S LIABILITY. If Landlord shall fail
to perform any term, condition, covenant or obligation required to be performed
by it under this Lease and if Tenant shall, as a consequence thereof, recover a
money judgment against Landlord, Tenant agrees that it shall look solely to
Landlord's right, title and interest in and to the Building, nor of any owner,
partner, member or manager in or of Landlord, for the collection of such
judgment; and Tenant further agrees that no other assets of Landlord shall be
subject to levy, execution or other process for the satisfaction of Tenant's
judgment.

     Section 13.05  NONWAIVER OF DEFAULTS. Neither party's failure or delay in
exercising any of its rights or remedies or other provisions of this Lease shall
constitute a waiver thereof or affect its right thereafter to exercise or
enforce such right or remedy or other provision. No waiver of any default shall
be deemed to be a waiver of any other default. Landlord's receipt of less than
the full rent due shall not be construed to be other than a payment on account
of rent then due, nor shall any statement on Tenant's check or any letter
accompanying Tenant's check be deemed an accord and satisfaction. No act or
omission by Landlord or its employees or agents during the Lease Term shall be
deemed an acceptance of a surrender of the Leased Premises, and no agreement to
accept such a surrender shall be valid unless in writing and signed by Landlord.

     Section 13.06  ATTORNEYS' FEES. If either party defaults in the performance
or observance of any of the terms, conditions, covenants or obligations
contained in this Lease and the non-defaulting party obtains a judgment against
the defaulting party, then the defaulting party agrees to reimburse the
non-defaulting party for reasonable attorneys' fees incurred in connection
therewith. In addition, if a monetary Default shall occur and Landlord engages
outside counsel to exercise its remedies hereunder, and then Tenant cures such
monetary Default, Tenant shall pay to Landlord, on demand, all expenses incurred
by Landlord as a result thereof, including reasonable attorneys' fees, court
costs and expenses.

governmental or political bodies.

     Section 15.04  EXAMINATION OF LEASE. Submission of this instrument by

this Lease shall be held to be invalid, void or unenforceable, the remaining
provisions shall remain in full force and effect. This Lease represents the

which consent shall not be unreasonably withheld or delayed.

     Section 15.12  PARKING. Tenant shall be entitled to the non-exclusive use

such event, to allocate parking spaces between Tenant and other tenants
equitably based upon each tenant's particular use of the Building. There will be
no assigned parking unless Landlord, in its sole discretion, deems such assigned
parking advisable. No vehicle may be repaired or serviced in the parking area
and any vehicle brought into the parking area by Tenant, or any of Tenant's
employees, contractors or invitees, and deemed abandoned by Landlord will be
towed and all costs thereof shall be borne by the Tenant. All driveways, ingress
and egress, and all parking spaces are for the joint use of all tenants. In
addition, Tenant agrees that its employees will not park in the spaces

termination agreement with JDS Uniphase Corporation, in form acceptable to
Landlord, by September 29, 2006 (the "Contingency Date"). Landlord shall notify
Tenant in writing on or before the Contingency Date as to whether the foregoing
contingency has been satisfied or waived. In the event that Landlord provides
notice that the contingency has not been satisfied or waived prior to the close
of business on the Contingency Date, then Landlord shall have the

                                     - 22 -
<Page>

right, but not the obligation, by written notice to the other party given prior
to the close of business on the Contingency Date to terminate this Lease.

     Section 15.15  RIGHT OF FIRST OFFER. Subject to any rights of first offer
granted to tenants under existing leases at the Property, Landlord hereby grants
Tenant a one time right of first offer with respect to space that is contiguous
to the Leased Premises (the "First Offer Space"). Provided that Tenant is not
then in Default hereunder, at such time that Landlord elects to actively market
the First Offer Space, Landlord shall give Tenant written notice of the terms
pursuant to which Landlord is willing to lease the First Offer Space to Tenant.
Unless (a) within ten (10) days following receipt of Landlord's notice Tenant
gives Landlord written notice accepting Landlord's proposed terms, AND (b)
within thirty (30) days following Tenant's notice or the parties' agreement to
terms as described in (a), Tenant executes and delivers to Landlord the
amendment to this Lease prepared by Landlord with respect to the First Offer
Space with terms substantially similar to this Lease (other than as to price),
from and after such applicable date (the "Trigger Date") Landlord shall be free
to lease the First Offer Space to any other person and on any terms, without any
further obligation to Tenant; provided that if Landlord fails to enter into a
lease for the First Offer Space within 90 days of the Trigger Date, then the
First Offer Space shall again be subject to the right of first offer of Tenant
as provided by this Section 15.15.

     Tenant acknowledges and agrees that the right of first offer and any other
rights granted under this Section 15.15 are granted exclusively to Tenant and
not to any assignee or sublessee of Tenant; provided, however that the rights
set forth herein shall, provided the same have not otherwise been previously
terminated, be available to any assignee of the entirety of Tenant's interest
hereunder, provided such assignee is a permitted assignee under and pursuant to
Section 11.02 of this Lease.

1.   TENANT ALLOWANCE. As a material inducement to Tenant to enter into this
Lease, Landlord hereby agrees to provide to Tenant an allowance in the amount
$159,392.50 (the "Tenant Allowance") to be used for the constructing of the
Tenant Improvements, fixturing of the Leased Premises and moving expenses.
Landlord shall pay the Tenant Allowance to Tenant, whether or not the expenses
have yet been incurred, within ten (10) business days following the Commencement
Date, provided that (a) Tenant is not in default under this Lease, and (b)
Tenant has commenced business operations in the Leased Premises.

2.   EARLY OCCUPANCY. Tenant is permitted entry to the Leased Premises on

shall comply with all terms and conditions of this Lease other than the
obligation to pay rent, and (b) Tenant shall not begin operation of its
business. Tenant shall indemnify Landlord against any injury, loss or damage
which may occur to any person or to any of the work in the Leased Premises or in
the Building, and to any personal property therein, all of which shall be at the
Tenant's sole risk and, prior to early entry by Tenant, Tenant shall provide
Landlord with proof of insurance coverage required of Tenant by this Lease.
Tenant acknowledges that Tenant shall be responsible for obtaining all
applicable permits and inspections relating to any such entry by Tenant.

3.   CONSTRUCTION OF TENANT IMPROVEMENTS. Tenant shall construct the Tenant
Improvements in substantial conformity with the plans and outline specifications
to be prepared by Tenant and approved in advance by Landlord, which approval
shall not be unreasonably withheld or delayed. In constructing the Tenant
Improvements, Tenant shall comply with the following provisions:

          (a)  The Tenant Improvements shall be performed by responsible
     contractors and subcontractors who shall not prejudice Landlord's
     relationship with Landlord's contractors or subcontractors or the
     relationship between such contractors and their subcontractors or
     employees, or disturb harmonious labor relations, and who shall furnish in
     advance and maintain in effect workmen's compensation insurance in
     accordance with statutory requirements and comprehensive public liability
     insurance (naming Landlord and Landlord's contractors and subcontractors as
     additional insureds) with limits satisfactory to Landlord;

          (b)  If the aggregate cost of the Tenant Improvements is equal to or
     in excess of one hundred fifty thousand dollars ($150,000) then prior to
     commencing the Tenant Improvements, Tenant must provide executed, effective
     waivers of mechanics liens from all contractors and all sub-contractors. In
     the event Tenant fails to provide executed and effective waivers, or if
     such waivers are not applicable under state law, Tenant must bond all such
     Tenant's Work prior to commencement;

          (c)  No such work shall be performed in such manner or at such times
     as to cause any delay in connection with any work being done by any of the
     Landlord's contractors or subcontractors in the Leased Premises or in the
     Building generally;

          (d)  All construction contracts for Tenant Improvements must include a
     provision holding the Landlord harmless from and against any and all claims
     arising from, under or in connection with such construction; and

          (e)  Tenant and its contractors and subcontractors shall be solely
     responsible for the transportation, safekeeping and storage of materials
     and equipment used in the performance of

<Page>

     such work, for the removal of waste and debris resulting therefrom, and for
