                               SUBLEASE AGREEMENT

     AGREEMENT made this 29th day of October, 2003, between Comverse, Inc., a
Delaware corporation, having a usual place of business at 100 Quannapowitt
Parkway, Wakefield, Massachusetts 01880, USA, as agent for Comverse Technology,
Inc., (hereinafter called the "Tenant"), and Picis, Inc., a Delaware corporation
with a usual place of business at 200 Quannapowitt Parkway, Wakefield, MA 01880
(hereinafter called the "Subtenant").

                                 WITNESSETH THAT

     WHEREAS, by a lease dated June 7, 1996, as amended (hereinafter called the
"Main Lease"), SCWakefield100 LLC, as successor in interest to WBAM Limited
Partnership (hereinafter called the "Landlord"), currently leases 168,000
rentable square feet of space in the building located at 100 Quannapowitt
Parkway, Wakefield, Massachusetts 01880, USA (the "Building") to the Tenant for
a term which ends on February 14, 2011; and

     WHEREAS, a true and accurate redacted copy of the Main Lease and all
amendments thereto is attached hereto as Exhibit "A" and incorporated herein by
reference; and

     WHEREAS, the Tenant has agreed to sublease the areas outlined as Space A on
the Plan attached hereto as Exhibit "B", containing approximately 31,355rentable
square feet on the fourth floor of the Building and designated as Suite 405 (the
"Premises") to the Subtenant on the terms stated herein; and

     WHEREAS, the Tenant has agreed to sublet at a future date the additional
area outlined as Space BB on said Plan, containing approximately 1,354 rentable
square feet, to the Subtenant on the terms stated herein, subject to
substitution as provided below.

     NOW, THEREFORE, it is agreed between the parties hereto as follows:

     1.   (a)  Tenant hereby leases to the Subtenant, and Subtenant hereby takes
and leases from the Tenant, the Premises for a period commencing on February 16,
2004 (the "Commencement Date"), and terminating on February 14, 2009 (the
"Term"). Time is of the essence of this Sublease. The Commencement Date shall be
extended, if necessary, if the date of Completion (as defined below) of
Build-Out (as defined below) of such Spaces is delayed by Tenant to a date later
than January 26, 2004. Subject to its determination of safety and the likelihood
of interference in construction, and subject to any applicable government
regulations, Tenant may permit Subtenant access to the Premises prior to
Completion. Tenant shall permit access to the Premises by Subtenant and its
contractors for the purpose of constructing Subtenant's Work, as set forth in
Exhibit D. Subtenant's status, and that of its contractors, during such
pre-Commencement period shall be that of licensees.

          (b)  Tenant reserves the right, exercisable no more frequently than
once in every three years, at Tenant's sole cost and expense, to relocate the
Premises to equivalent space (in terms of quantity, configuration, and
Build-Out) elsewhere in the Building.

<Page>

          (c)  Notwithstanding anything contrary contained in the currently
existing sublease agreement dated as of May 13, 1999, as amended (the "Old
Sublease"), the parties hereby acknowledge and agree that, until the
Commencement Date, Subtenant shall continue to occupy and use the premises (the
"Old Premises") sublet under the "Old Sublease" from Tenant at a base rent rate
of $14.50 per rentable square foot per year. The parties further agree that the
term of the Old Sublease is hereby extended until the Commencement Date (as same
may have been extended pursuant to the third sentence of section 1(a)), and that
except as amended and modified by this Section 1(b), all provisions of the Old
Sublease shall remain in full force and effect and this Section 1(b) shall be
deemed to have amended the Old Lease accordingly. Notwithstanding the foregoing,
if the Commencement Date has occurred but subtenant has not taken occupancy of
the Premises, Tenant agrees to permit Subtenant to occupy the Old Premises, and
to waive rent under the Old Sublease, for a period not to exceed ten business
days, or until Subtenant sooner occupies the Premises.

          (d)  The parties have agreed, based on their own surveys and
inspections, that for purposes of this Sublease the Premises (Space A) comprises
31,355rentable square feet, and that Space BB comprises 1,354 rentable square
feet. Said determination and agreement shall be binding and conclusive on the
parties; no variation from such figure based on any physical measurement shall
be admissible to affect the obligations of either party hereunder.

          (e)  The Subtenant shall have the right, as its sole option, by giving
unconditional notice thereof to the Tenant at least nine (9) months prior to the
expiration of the Term, to extend the Term of this Sublease through February 14,
2011 (the "Extension Term") on the same terms and conditions as herein set
forth, other than Base Rent, provided it is understood and agreed that such
Extension Term shall be exercisable only if at the time of exercise there exists
no material default on the part of the Subtenant under this Sublease which has
not been cured within the time available for cure hereunder. Unless otherwise
expressly agreed in writing, the failure to give such notice in a timely fashion
as set forth above shall be deemed an irrevocable election on the part of the
Subtenant not to exercise such extension option. The Annual Base Rent for the
Extension Term will be the Fair Rental Value of the Premises as of the
commencement of the Extension Term, as determined in accordance with the
procedures set forth in Exhibit C attached hereto.

          (f)  Upon the expiration of the existing sublease covering Space B, or
upon any earlier expiration or termination of such sublease, then the space
designated as Space B shall be added to the Premises upon Completion (as defined
below) of the Space B Build-Out (as defined below), and Tenant shall make Space
B available for Subtenant's occupation by no later than August 15, 2004 (the
"Expansion Date"). Upon Completion and acceptance by Subtenant of Space B, the
term Premises shall include Spaces A and B and Rent and all the provisions of
this Sublease shall become immediately applicable thereto, the entire

          (g)  Subject to the rights of other subtenants of Tenant, and to
Tenant's own requirements for office space in the Building, Tenant agrees to
give Subtenant a right of first offer for each and all spaces laterally
contiguous to the Premises (each an "Available Space"), at such time as same may
become available for sublease, on such terms as Tenant shall establish therefor.
Tenant shall not for six months thereafter sublease such Available Space on
terms

                                        2
<Page>

whose aggregate value is less than eighty-five percent (85%) of the amount
Subtenant would have paid pursuant to the offer terms under this section.

          (h)  Each party shall have the right, exercisable effective as of the
end of the third full year of the Term, upon no less than nine months' advance
written notice, to terminate this Sublease. If Subtenant exercises this right,
it shall upon termination pay to Tenant the unamortized portion of the
transaction costs of this Sublease ("Early Termination Charges"), including
without limitation the cost of improvements on behalf of Subtenant, brokerage
fees, and legal fees, plus an additional amount equal to two months' Rent at the
rate for the said third year. If Tenant exercises this right, then upon
termination Subtenant shall be relieved of any obligations hereunder for Rent
beyond the date of termination, as well as for any other obligations hereunder
not accrued as of the date of termination (including, without limitation, any
Early Termination Charges), and Tenant shall refund Subtenant's Security
Deposit, net of amounts for which Tenant may otherwise apply such Security
Deposit pursuant to this Sublease.

          (i)  It is expressly understood and agreed that this Sublease is
subject to the Landlord's approval of this Sublease. Tenant shall use reasonable
efforts to obtain such approval by the Landlord.

          (j)  Tenant grants to Subtenant, as an appurtenance of the Premises
but not as part thereof, the right to use 3.5 of the unreserved employee parking
spaces adjacent to the Building, in the open lots or the covered garage, per
1000 square feet of the Premises occupied by Subtenant hereunder (i.e., 95
spaces as of the Commencement Date, increasing ratably to 109 spaces upon
occupancy of the entire Premises). Visitor spaces, so designated, shall be
available on a first-come-first-served basis to all tenants and subtenants of
the Building.

     2.   (a)  Tenant hereby represents and warrants that the documents attached
hereto as Exhibit A is a redacted copy of the Main Lease and all of its
amendments thereto, and that no provision of the Main Lease that has been
excised from the inspection copy contains matter material to Subtenant's
obligations under this Sublease. Subtenant represents and warrants that it has
had a full and complete opportunity to review an inspection copy of the Main
Lease.

          (b)  Subtenant hereby expressly agrees and covenants to the Landlord,
who has given its consent in a separate document, and to the Tenant, that
Subtenant assumes, is bound by and shall faithfully perform all of the
obligations of the Tenant as tenant under the Main Lease, insofar as same affect
the Premises or the parties' rights and obligations hereunder, except as
otherwise expressly provided for herein. It is understood and agreed that the
interest of the Subtenant hereunder and in and to the Premises is subject and
subordinate to the Main Lease. It is further agreed that the relationship
between, and rights of, the Subtenant and Tenant shall, except as expressly
provided for herein, be governed by the Main Lease and that the Tenant
specifically shall have all the rights granted to the Landlord under the Main
Lease with respect to the enforcement of the provisions of this Sublease
Agreement (including without limitation available remedies) and the termination
hereof, and shall have all the privileges, immunities, and limitations of
liability of the Landlord insofar as applicable to this Sublease, provided
however, that the Tenant shall not be deemed to guarantee performance by the
Landlord of its obligations under the Main Lease and the Tenant shall have no
obligation to the Subtenant for any default in this Sublease Agreement caused by
the default or any other act of the Landlord under the Main

                                        3
<Page>

Lease. For avoidance of doubt, the foregoing sentence does not affect any
obligations of Tenant hereunder undertaken directly to Subtenant, including
without limitation the obligation to use reasonable efforts to intercede with
Landlord set forth in section 7(a). It is further agreed that performance by
Tenant of certain obligations hereunder may be conditional upon the performance
by the Landlord of its obligations under the Main Lease, which obligations
Tenant agrees to use reasonable efforts to enforce.

     3.   (a)  Subtenant covenants and agrees with Tenant to pay to Tenant as
Base Rent during the term hereof, without prior notice or demand and without
deductions, counterclaims or setoff, the annual sums set forth in the table
below, payable in equal monthly installments as also set forth in such table,
due on the first day of each month in advance, commencing on the Commencement
Date. In the event that the Term commences or terminates on a day other than the
first day of the month, the Rent for such period of less than a month, shall be
calculated on a pro rata basis.

          (b)  In addition to and concurrently with the Base Rent, Subtenant
shall pay, as additional Rent, the following.

               (i)    an assessment for electric usage, currently at the rate of
     $1.07 per rentable square foot, to be recalculated in February 2004 and
     annually thereafter;

               (ii)   its proportionate share of real estate taxes and operating
     expenses calculated pursuant to the Main Lease, in excess of the amounts
     payable in respect of the 2004 fiscal year for taxes and calendar year 2004
     for operating expenses, at such time as same shall be payable by Tenant to
     Landlord. For purposes hereof, Subtenant's proportionate share shall be
     eighteen and two-thirds percent (18.66%) with Space A only, and nineteen
     and forty-seven one-hundredths percent (19.47%) with Spaces A and B. Tenant
     covenants and agrees that Subtenant may, pursuant to a request delivered to
     Tenant within sixty (60) days of receipt of Tenant's notice of Subtenant's
     share of operating expenses and real estate taxes due, at its own cost and
     expense, audit and otherwise examine Tenant's records (including any
     pertinent data received from Landlord) supporting such calculations.

          (c)  Certain amenities of the Building, such as after-hours HVAC and
the use of the Quannapowitt Fitness Center, are subject to additional usage
charges. After-hours HVAC shall be available upon reasonable advance notice to
Tenant, at the rate of $50.00 per hour;

(2)  Or other date Space B is added to Premises

                                        4
<Page>

Fitness Center charges are determined by its management. The term "after-hours"
shall mean any time other than (i) 6:00AM to 6:00PM, Monday through Friday and
(ii) 8:00AM to 5:00PM on Saturday and Sunday.

          (d)  Rent payable by Subtenant hereunder shall be paid to Tenant at
the following address: Comverse, Inc., 100 Quannapowitt Parkway, Wakefield,
Massachusetts 01880, or such other place as Tenant may from time to time
designate in writing.

     4.   Subtenant covenants and agrees to use the Premises for general office
use and for no other purpose. During Subtenant's use and occupancy of the
Premises, Subtenant shall comply with all of the provisions of the Main Lease
and any Rules and Regulations thereunder, except to the extent inconsistent with
the provisions of this Sublease. Except as otherwise set forth herein or in
respect of Tenant's exercise of remedies for breach, each party shall comply
with the other party's reasonable security regulations, and shall observe all
requirements of security during and after hours. Subtenant acknowledges and
agrees that except as may be otherwise expressly provided, e.g. Tenant's
warranties with respect to Build-Out, the Premises are being leased to Subtenant
in their "AS IS" condition (including Tenant's fixtures, improvements,
furniture, equipment and personal property) and Tenant does not warrant and
represent the adequacy or sufficiency of the Premises, the Building, the Common
Areas, any improvements or furnishings therein or thereto or the real estate of
which they constitute a part, or any part thereof, for Subtenant's present or
future operations.

     5.   (a)  Except as contemplated in the Build-Out (as defined below),
Subtenant shall not undertake or make any alterations, additions, improvements
or changes in or to the Premises except in accordance with the terms of the Main
Lease (including the requirement of Landlord's prior written consent) and with
the prior written consent of Tenant, which consent shall not be unreasonably
withheld or delayed (except insofar as such consent is contingent on approval or
consent by Landlord), including, without limitation, Tenant's prior written
approval of all plans, drawings and specifications relating to any such
alteration, addition, improvement or change. Subtenant shall be permitted to
utilize the office subdividers and wiring systems currently in place and to
connect data and telephone wiring to Subtenant's own systems, and Subtenant
shall further be entitled to use the existing telephone handsets. Subtenant
shall not modify the electrical, telephone or data wiring in the Premises in
such a manner as to prevent their ready reconversion to Tenant's use at the
termination of the Sublease, and shall work with Tenant's telecommunications
consultant to ensure that any configuration of Subtenant's telephone systems
impedes neither Tenant's own system nor the reintegration of Subtenant's wiring
into Tenant's system upon such termination.

          (b)  All Subtenant's Work (as defined below) shall, except as
otherwise expressly agreed in writing by Tenant, be performed at Subtenant's
sole cost and expense and in full compliance with the Main Lease.

          (c)  Tenant shall cause the Premises to be demised in accordance with
the requirements hereof, and shall construct and improve each of Spaces A and B
(or substitute thereof), in accordance with Exhibit D attached hereto and any
other plans to be developed by Tenant and approved by Subtenant prior to
construction commencement (each, a "Build-Out" and collectively, the
"Build-Out"). To the extent set forth in Exhibit D as the responsibility of

                                        5
<Page>

Tenant, the Build-Out shall be provided at Tenant's sole cost, except to the
extent set forth in section 9. "Completion" with respect to each Build-Out that
includes no Subtenant Work shall mean the earlier of (1) the sixth working day
after Tenant has obtained and delivered to Subtenant a certificate of occupancy
with respect to the applicable Space(s) and has made such Space(s) available for
inspection by Subtenant (the "Inspection Period") and Subtenant had not
reasonably objected to deeming such Build-Out complete; or (2) Subtenant's
accepting delivery of such Space(s) as substantially complete, with mutually
agreed to "punch list" items that do not materially interfere with Subtenant's
occupancy of such Space(s), and that the Tenant shall make diligent efforts to
complete within a reasonable time thereafter. "Subtenant (or Subtenant's) Work"
with respect to any Build-Out or other improvements constructed by Subtenant
during the Term, shall mean the work for which, pursuant to Exhibit D or any
other applicable statement of work, Subtenant is responsible for performing or
having performed the work in question. "Completion" with respect to any
Build-Out that includes Subtenant Work shall mean the earlier of (3) the sixth
business day after Tenant has notified Subtenant that it has substantially
completed its work in connection with the Build-Out and the applicable Space is
ready for the final portion of Subtenant's Work to commence, and has made such
Space available for the Inspection Period, and Subtenant had not reasonably
objected to deeming such Build-Out complete, or (2) Subtenant's acceptance of
delivery of the Space in question as substantially ready for the commencement of
Subtenant's Work, with mutually agreed to "punch list" items that do not
materially interfere with Subtenant's Work, and that Tenant shall make diligent
efforts to complete within a reasonable time following Subtenant's notification
to Tenant that it has completed Subtenant's Work. Tenant shall be responsible
for obtaining any necessary Certificate of Occupancy for the Space in question
following completion of Subtenant's Work; any delay in obtaining such
Certificate of Occupancy occasioned by Subtenant's failure to complete
Subtenant's Work in accordance with the parties' agreed timetable shall not
delay the addition of the Space in question to the Premises for purposes of
Rent, but Subtenant shall not be permitted to occupy such Space in violation of
the applicable regulations pertaining thereto..

          (d)  Tenant shall furnish Subtenant no later than by the Commencement
Date, at Tenant's sole expense, with building standard signage on the monument
in front of the Building, in the lobby of the Building and at the fourth floor
landing. Subtenant may at its own expense install signage at the entrance to the
Premises. In addition, if the existing subtenant adjacent the Premises vacates
the Building, or if for any other reason its existing garage signage is removed,
then subject to Landlord and regulatory approval, Tenant grants Subtenant the
right, at Subtenant's sole cost and risk, to signage on the Building garage
similar to that of such vacating subtenant; provided, however that if Tenant
executes a sublease with a third party that occupies more space in the Building
than Subtenant, and such third party requests the right to garage signage, then
Subtenant shall promptly upon notice from Tenant remove its garage sign, at its
sole cost and expense..

          (e)  Tenant represents and warrants that each Build-Out of a Space
shall materially comply and conform to the applicable Build-Out specifications.
Should such Build-Out, or any portions thereof, not materially conform or be in
compliance, or contain latent defects (other than Building latent defects,
liability for which Tenant hereby expressly disclaims), Tenant shall, at its
option, repair or replace the non-complying, non-conforming or defective
portion(s) of such Build-Out, in a manner and within a time period reasonably
satisfactory to Subtenant.

                                        6
<Page>

          (f)  Subtenant shall have access to all Building common areas and to
the standard amenities of the campus of which the Building forms a part,
including without limitation, restrooms located in common areas, elevators, the
cafeteria at the Building, and the Quannapowitt Fitness Center, subject to the
latter's standard charges.

     6.   Subtenant shall, at its sole cost and expense, keep in full force and
effect during the term hereof, with companies reasonably acceptable to Tenant
and authorized to do business in the Commonwealth of Massachusetts, insurance of
the types and in such limits as Tenant reasonably requires, including, but not
limited to, public liability and property damage insurance. Subtenant
acknowledges that Tenant has advised it that Landlord requires subtenants in the
Building to maintain the same level and types of insurance that Tenant is
required to maintain under the Main Lease, and that Tenant's requirements are
therefore the same as those of Landlord. Subtenant shall, upon request by
Tenant, furnish Tenant with a certificate of such policy or policies and
thereafter with any renewals thereof. Such policies shall name Tenant and
Landlord as additional insured parties and shall be primary and non-contributing
with any insurance carried by Tenant. Said policies shall provide that they
shall not be canceled or modified without thirty (30) days prior written notice
to Tenant.

     7.   (a)  Subtenant shall, at Subtenant's sole cost and expense, keep the
Premises, equipment, facilities, fixtures and furniture therein, neat, clean and
in as good order, repair and condition as when Subtenant took possession or as
the same may be put in during the term of this Agreement, ordinary wear and tear
excepted, and shall perform all obligations of Tenant under the Main Lease with
respect thereto, it being agreed and understood that Tenant shall not be
required to repair or maintain any part or portion of the Premises. Except as
may otherwise be provided in this Sublease, Tenant shall not now or at any time
in the future be required to make any expenditures whatsoever with respect to
the Premises otherwise required to be made by Landlord, and does not assume any
obligation to perform the terms, covenants and conditions contained in the Main
Lease on the part of Landlord to be performed. In the event that Landlord should
fail to perform any of the terms, covenants and conditions contained in the Main
Lease applicable to the Premises or in respect of Subtenant, Tenant's sole
responsibility and liability shall be to use reasonable efforts to present
Subtenant's requests, demands and claims, and facilitate discussions with
Landlord. For avoidance of doubt, Tenant shall not be obliged to commence
litigation against, or defend claims or litigation brought against Subtenant by
Landlord.

          (b)  Upon the expiration or earlier termination hereof, Subtenant
shall deliver possession of the Premises to Tenant in as good order, condition
and repair as when Subtenant took possession thereof or as the same may have
been put in during the term hereof, ordinary wear and tear thereof excepted.

     8.   (a)  Subtenant shall comply with all of the requirements applicable to
the Premises or any part thereof now or hereafter in force of all governmental
authorities, and of insurance carriers for whose requirements Subtenant has been
given notice. Subtenant shall indemnify Tenant and hold Tenant harmless from and
against any loss, cost, damage, liability and expense by reason of failure to do
so in any respect or by reason of any accident, injury (including death), loss
or damage, resulting to person or property by reason of any act done or

                                        7
<Page>

failure to act upon the Premises by Subtenant or Subtenant's agents, employees,
invitees and/or contractors.

          (b)  Neither Tenant nor its agents, employees or contractors shall be
liable for any accident, injury (including death), loss or damage resulting to
any person or property sustained by Subtenant or Subtenant's agents, employees,
invitees and/or contractors, or any occupant of the Building or anyone claiming
by or through them resulting from any latent defect in the Building or the
Premises, or in any equipment or appurtenances in same, or resulting from any
accident or occurrence in or about the Building or the Premises, or resulting
directly or indirectly from any acts of negligence of any tenant or occupant of
the Building, or of any personwhatsoever, unless such accident, injury, loss or
damage was a result of Tenant's gross negligence or willful misconduct. All
property of Subtenant, Subtenant's agents, employees, contractors and invitees,
or of any occupant or user of the Premises shall be at the sole risk of such
person only, and Tenant shall not be liable for any damage thereto except as
aforesaid.

          (c)  Subtenant agrees to indemnify and hold the Tenant harmless from
and against any claim of the Landlord under the Main Lease, and against any
claim for injury to persons, including death, and for property damage, arising
out of the occupancy and use of the Premises by Subtenant, its officers,
partners, employees, agents or invitees.

     9.   As security for its obligations hereunder, Subtenant agrees to the
following provisions:

          (a)  Tenant shall retain the security deposit deposited by Subtenant
pursuant to the Old Sublease (the "Security Deposit") in the amount of
$112,560.50. The Security Deposit shall be held by the Tenant, without
obligation for interest or otherwise, as security for the performance of
Subtenant's covenants and obligations under this Sublease. It is expressly
understood and agreed that such deposit is not an advance rental deposit or a
measure of Tenant's damages in the case of Subtenant's default. Upon the
occurrence of any event of default by Subtenant, Tenant may, from time to time,
without prejudice to any other remedy provided herein or provided by law or
equity, use such fund to the extent deemed necessary in Tenant's sole discretion
to make good any arrears of Rent or other payments due Tenant hereunder, and any
other damage, injury, expense or liability caused by such event of default.
Subtenant hereby agrees to increase on demand the amount so applied in order to
restore the Security Deposit to its original amount.

          (b)  Tenant agrees to refund to Subtenant, within thirty (30) days
following commencement of the fourth year of the Term, if the parties have not
exercised their termination options pursuant to section 1(h), so much of the
Security Deposit as exceeds one month's Base Rent for the fourth year of the
Term, provided that Subtenant has theretofore timely paid all Rent and other
obligations owing to Tenant hereunder, and is otherwise not in material breach
of this Sublease beyond any applicable cure period.

     10.  This Sublease, and the rights and obligations of all parties hereto,
is subject to the condition precedent of the consent of Landlord to this
Sublease, such consent to be in form and substance satisfactory to the Tenant.

                                        8
<Page>

     11.  With respect to any damage or destruction by fire or other casualty,
or any taking by eminent domain, the provisions of the Main Lease shall govern;
it being understood that Tenant shall have the right, without Subtenant's
consent, to make whatever elections are provided to Tenant under the Main Lease
at Tenant's sole discretion.

     12.  If Subtenant retains possession of the Premises or any part thereof
after the termination of the term of this Sublease whether by lapse of time or
otherwise without the express written consent of Tenant, which Tenant may
withhold in its sole discretion unless otherwise expressly stated herein,
Subtenant shall pay to Tenant, as an occupancy charge, an amount equal to twice
the Rent and other sums required to be paid under this Sublease. In addition and
without limiting any other rights and remedies which Tenant may have on account
of such holding over by Subtenant, Subtenant shall pay to Tenant all direct and
consequential damages suffered by Tenant on account of such holding over by
Subtenant, including, without limitation, any costs and expenses which the
Landlord charges to the Tenant on account thereof.

     13.  (a)  Subtenant shall not sublet (which term shall be deemed to include
the granting of concessions and licenses and the like) the Premises, or any
portion thereof, or in any way assign, transfer, mortgage or pledge this
Sublease, or suffer or permit the same to be assigned or transferred by
operation of law or otherwise; or permit the occupancy of the Premises by anyone
other than Subtenant (collectively, an "assignment" and the other party an
"assignee"), except in accordance with the following subsections of this
section. Any such subletting or assignment in violation of said provisions shall
be a material breach of this Sublease and shall be deemed null and void.

          (b)  Subtenant may sublet the Premises, or any portion thereof, or
assign this Sublease to a parent, subsidiary, company under common control with
Subtenant, or its successor by merger or acquisition, subject to the consent of
Landlord pursuant to the Main Lease, and of the Tenant, whose consent shall not
be unreasonably withheld, conditioned or delayed; and in no case shall such
subletting or assignment operate to relieve Subtenant of its obligations
hereunder.

               (i)    For purposes of this section, in the case of a proposed
     assignment to a successor of Subtenant by acquisition or merger, and
     without prejudice to any other reasonable determinations by Tenant, Tenant
     shall not be deemed to have withheld, conditioned, or delayed approval
     unreasonably if it concludes, based upon review of financial information it
     receives from Subtenant or the proposed successor, or otherwise acquires
     from third parties, that the proposed successor would have net worth,
     immediately following completion of the acquisition or merger, less than
     that of Subtenant immediately prior to such acquisition or merger.

          (c)  Subtenant may engage in transactions to which this section
relates with unrelated parties, subject to the prior consent of Landlord
pursuant to the Main Lease, and of Tenant, whose consent shall not be
unreasonably withheld, conditioned or delayed, provided that the following
procedures are followed and the following criteria applied.

          (d)  For purposes of implementing the requirements of this section 13,
the parties agree to the following procedures:

                                        9
<Page>

               (i)    Subtenant shall notify Tenant in writing no less than
     thirty (30) days prior to the effective date thereof of Subtenant's intent
     to so assign this Sublease or sublet the Premises and the proposed
     effective date of such subletting or assignment, shall furnish Tenant a
     copy of the proposed sub-sublease (for convenience called "sublease" and
     the other party a "subtenant") or assignment, and shall request in such
     notification that Tenant and Landlord consent thereto.;

               (ii)   Tenant shall forward Subtenant's request to Landlord
     within one business day following receipt thereof from Subtenant, and shall
     complete its own review and notify Subtenant of its conclusion within ten
     business days following such receipt.

               (iii)  Without limitation, Tenant shall not be deemed to have
     unreasonably withheld consent to the proposed transaction if the following
     conditions have not been met:

                      (A)  the assignee or subtenant shall use the Premises only
          for the uses permitted to Subtenant hereunder;

                      (B)  the proposed assignee or subtenant has a net worth
          and creditworthiness sufficient in Tenant's reasonable judgment to
          meet the obligations imposed by the assignment or the sublease (or
          meets the requirements of section 13(b) in the cases to which it
          applies);

                      (C)  the proposed assignee or subtenant is not a direct
          competitor of Tenant, in Tenant's reasonable determination;

                      (D)  the proposed assignee or subtenant is not currently a
          subtenant of Tenant in the Building or the campus of which the
          Building forms a part (except in cases to which section 13(b)
          applies);

                      (E)  the business proposed to be conducted by the assignee
          or subtenant is of a character compatible with the other tenants and
          subtenants within the Building or the campus of which the Building
          forms a part;

                      (F)  the operations of the proposed assignee or subtenant
          will not excessively burden the Building systems, parking and common
          areas and facilities of the Building or require excessive
          administration on the part of Tenant.

                      (G)  the proposed assignee or subtenant has not fully
          undertaken all Subtenant's obligations under this Sublease and
          corresponding obligations under the Main Lease pertinent to the nature
          of the subleased or assigned portion of the Premises (which in cases
          to which section 13(b) applies may be by operation of law).

                      (H)  Subtenant has not remained fully and primarily liable
          to Tenant for its obligations under this Sublease irrespective of any
          assignment or sublease (except in cases to which section 13(b) applies
          and Subtenant will not continue as an entity with substantial assets).

                                       10
<Page>

               (iv)   If Tenant consents to the proposed transaction, then
     Subtenant may conclude same following receipt of Landlord's consent. If
     Landlord's consent imposes conditions in addition to those imposed by
     Tenant, such additional conditions shall be deemed incorporated into
     Tenant's consent. If Landlord's consent imposes conditions that are
     inconsistent with those imposed by Tenant, then Tenant's consent shall be
     deemed revoked, and the parties and Landlord shall endeavor to harmonize
     the terms of consent.

               (v)    If Tenant declines consent, then the parties, through
     Subtenant's Chief Financial Officer and Tenant's Assistant Vice President
     for Facilities, shall confer within five business days following Tenant's
     notice declining consent, to seek resolution. If within ten business days
     following such notice the parties cannot reach agreement on terms that
     would make the proposed transaction acceptable to Tenant, then if Subtenant
     nevertheless proceeds with the proposed transaction, the provisions of this
     Sublease and the Main Lease as incorporated herein with respect to material
     breach shall apply, except that Tenant shall take no action with respect to
     seeking eviction of Subtenant for a period of thirty (30) days following
     the consummation of a proposed transaction to which section 13(b) applies.

          (e)  Subtenant shall furnish Tenant with any information reasonably
requested by Tenant to enable it to determine whether the proposed assignment or
subletting complies with the foregoing requirements, including without
limitation, financial statements relating to the proposed assignee or subtenant.

          (f)  Subtenant shall, as Additional Rent, reimburse Tenant promptly
for Tenant's reasonable legal expenses incurred in connection with any request
by Tenant for such consent. If Tenant consents thereto, no such subletting or
assignment shall in any way impair the continuing primary liability of Subtenant
hereunder, and no consent to any subletting or assignment in a particular
instance shall be deemed to be a waiver of the obligation to obtain the Tenant's
written approval in the case of any other subletting or assignment.

          (g)  If for any assignment or sublease consented to by Tenant
hereunder Subtenant receives rent or other consideration, either initially or
over the term of the assignment or sublease, in excess of the rent called for
hereunder, or in case of sublease of part, in excess of such rent fairly
allocable to the part, after appropriate adjustments to assure that all other
payments called for hereunder are appropriately taken into account and after
deduction for reasonable marketing expenses of Subtenant in connection with the
assignment or sublease (i.e., brokerage commissions, legal fees, architects and
engineers fees, and amortized costs of improvements for a subtenant amortized
over the sublease term), to pay to Tenant as additional Rent fifty (50%) percent
of the excess of each such payment of rent or other consideration received by
Subtenant promptly after its receipt.

          (h)  If Subtenant presents to Tenant a request for consent to any
subletting or assignment, other than one to which section 13(b) relates, and
Tenant reasonably determines that the portion of the Premises affected thereby
is needed for Tenant's internal use, then in lieu of consenting to the
assignment or subletting, Tenant may opt, within the period set forth above for
its approval, to terminate the Sublease as to the portion of the Premises, from
and after the

                                       11
<Page>

proposed effective date presented by Subtenant, and the provisions of the last
sentence of section 1(h) shall apply ratably to the portion of the Premises
thereby affected. Except as set forth in this subsection, if Tenant rejects a
proposed assignment or subletting, Tenant shall not for one year thereafter
sublet equivalent space to the rejected sub-subtenant or assignee.

          (i)  If at any time during the term of this Sublease, there is a name
change, reformation or reorganization of the Subtenant entity, Subtenant shall
so notify Tenant and deliver evidence reasonably satisfactory to Tenant
documenting such name change, reformation or reorganization. If, at any time
during the term of this Sublease, there is a transfer of a controlling interest
in the stock, membership or general partnership interests of Subtenant,
Subtenant shall so notify Tenant and (whether or not Subtenant so notifies
Tenant) such transfer shall be deemed an assignment subject to sections 13 (a)
and (b). This paragraph shall not apply if the Subtenant is a corporation and
the outstanding voting stock thereof is listed on a federally registered
securities exchange.

     14.  Unless otherwise directed by the Tenant thirty (30) days prior to the
expiration of this Sublease, the Subtenant shall, before the end of the Term and
at its own expense: (a) remove all partitions and improvements to the Premises
that can be removed without material injury to the Premises, except for the
partitions that were in place at the Commencement Date; (b) repair all injury
done by such installation or removal; and (c) restore and surrender the Premises
to the condition they were in at the beginning of the Term, reasonable wear and
tear thereof excepted. All property of Subtenant remaining on the Premises after
the expiration of this Sublease Agreement shall be deemed abandoned.

     15.  The Tenant hereby reserves the right to enter onto the Premises during
business hours from time to time to ascertain whether the Subtenant is in
compliance with the provisions of this Sublease Agreement; provided that except
in cases of emergency Tenant gives Subtenant reasonable prior written notice of
such entry. Except in cases of emergency, such entry of the Premises by Tenant
shall be subject to Subtenant's security procedures, which security procedures
may include without limitation requirements that Tenant's entry into certain
areas of the Premises be accompanied by a representative of Subtenant (unless
Subtenant shall refuse such accompaniment). Tenant shall exercise its rights
hereunder so as to minimize any material adverse effect on Tenant's conduct of
its business in the Premises, that are otherwise not in violation of this
Sublease or that contribute to a hazard or emergency condition.

     16.  (a)  The Tenant warrants and represents that it is not in any default
and does not have knowledge of any Landlord defaults under the Main Lease; that
the Main Lease is in full force and effect and that the Tenant has a good right
to sublease its interest in the same as herein provided, subject to the written
consent of the Landlord; that the leasehold interest of the Tenant is not
encumbered; and that the Tenant has done nothing to defeat or impair this
Sublease Agreement. The Tenant further warrants and covenants that it will
comply with all of its obligations and restrictions under the Main Lease
material to this Sublease, including without limitation paying all rents as they
become due under the Main Lease and that the Subtenant, upon the performance of
its obligations hereunder and subject to the provisions hereof, shall for the
term hereof with respect to the Premises, succeed to all rights of Tenant under
the Main Lease and will have quiet possession and enjoyment of the Premises;
provided, however, that Subtenant has no right and by this Sublease Agreement is
granted no right to exercise any right

                                       12
<Page>

to extend the term or right to expand the Premises which may have been granted
by Landlord to Tenant under the Main Lease or any extension or amendment
thereof;. If any provisions of this Sublease shall be in violation of the
provisions of the Main Lease, the provisions of the Main Lease shall be deemed
to limit the provisions hereof. It is expressly understood and agreed, however,
that nothing stated in this Section 16 shall be deemed to confer upon the
Subtenant any greater rights than are set forth herein or in any document
incorporated herein by reference, nor limit any of the Subtenant's obligations
hereunder or in such incorporated documents.

     17.  Subtenant agrees to do nothing which will subject the Main Lease to
termination by the Landlord under the provisions of the Main Lease, and it is
further agreed that if the Subtenant is in default of the provisions of the Main
Lease, the Tenant may, in accordance with the applicable provisions of the Main
Lease, but need not, cure said default specifically on behalf of and for the
account of the Subtenant but in which case all reasonable costs, damages, and
expenses incurred by the Tenant in connection therewith shall be paid to the
Tenant by Subtenant immediately upon Tenant's demand therefor as additional rent
hereunder. In addition to any terms of the Main Lease governing rights to cure
Subtenant's defaults that have been incorporated herein mutatis mutandis, by
curing the Subtenant's default on its behalf and count, as aforesaid, the Tenant
shall not be deemed to have waived any of its rights nor have released the
Subtenant from any of its obligations under this Sublease Agreement. In the
event that the Main Lease is terminated by the Landlord by reason of Subtenant's
default, the Subtenant shall indemnify and hold the Tenant harmless from such
damages as Tenant may become liable to pay under the Main Lease resulting from
such default, plus all other expenses and costs related thereto, including,
without limitation, reasonable attorney's fees.

     18.  All notices to be given under this Sublease Agreement shall be hand
delivered or sent by prepaid registered mail, overnight courier, return receipt
requested, or by hand, and if addressed to the Subtenant shall be sent to the
Premises, and if addressed to the Tenant shall be sent addressed to Comverse,
Inc., 100 Quannapowitt Parkway, Wakefield, Massachusetts 01880, USA, Attention:
Director of Facilities, unless in either case a different address is specified
by either party to the other in writing by prepaid registered mail, return
receipt requested.

     19.  If any provision of this Sublease Agreement, or the particular
application thereof, shall to any extent be held invalid or unenforceable by a
court of competent jurisdiction, the invalidity of such provision shall not be
deemed to affect the validity of any other provision of this Sublease Agreement.
Such invalid provisions shall be deemed to be stricken from this Sublease
Agreement, which shall otherwise continue in full force and effect in all
respects.

     20.  This Sublease Agreement shall be binding upon and inure to the benefit
of the parties hereto and their respective successors, assigns, heirs and legal
representatives, but this provision shall not operate to permit any assignment,
subletting, mortgage, lien, charge, or other transfer or encumbrance contrary to
the provisions of this Sublease.

     21.  This Sublease Agreement shall be governed by and construed in
accordance with the laws of the Commonwealth of Massachusetts.

     22.  All capitalized terms used and not otherwise defined herein shall have
the same meaning herein as affixed to them in the Main Lease.

                                       13
<Page>

     23.  No modification, waiver or amendment of this Sublease or of any of its
conditions or provisions shall be binding upon Tenant unless the same be in
writing and consented to by Tenant.

     24.  Subtenant's use of the Premises will not result in or involve the use,
generation, manufacture, refining, transportation, treatment, storage, handling
or disposal of, or the conduct or performance of any activity in connection
with, any hazardous substance or hazardous waste, as such terms are defined
under state or federal law, which would subject the Premises or Tenant to any
liability, including damages, penalties or fines, or any lien on the Premises
under such laws or regulations. Subtenant shall indemnify and hold harmless
Landlord and Tenant, their respective directors, officers, partners and any of
their respective employees, from and against all costs incurred (including
without limitation amounts paid pursuant to penalties, fines, orders), arising
out of any claim made by Federal, State or local agencies or departments or
private litigants or third parties with respect to violations by Subtenant, its
agents or employees of environmental or health laws, rules, regulations, orders
or common law, provided such violations are caused by Subtenant or are related
to Subtenant's use of the Premises. For its part, Tenant represents that it has
not in connection with its use and occupancy of the Premises brought any
hazardous materials into the Premises or the Building in violation of the Main
Lease.

     25.  Tenant and Subtenant, for themselves and on behalf of their respective
agents, affiliates, successors and assigns, covenant and agree that during the
period of time beginning with the execution of this Sublease and ending one year
after expiration or termination hereof or of any renewal hereof, neither party
shall directly or indirectly solicit for the purpose of employment, or employ as
employee or "contract employee" any employee of the other in the Commonwealth of
Massachusetts. If at any time this provision is found to be overly broad under
the laws of an applicable jurisdiction, then this provision shall be modified as
necessary to conform to such laws rather than be stricken. This section shall
not apply to general solicitations of employment made by a party and not
directed specifically, by publication, email, posting, or otherwise, at
employees of the other party, or to employment of any person in response to such
a general solicitation.

     26.  Tenant and Subtenant, for themselves and on behalf of their respective
agents, affiliates, successors and assigns, covenant and agree to keep the terms
of this Sublease Agreement and all negotiations relating hereto in strictest
confidence and agree not to disseminate or disclose any such information to any
third party, with the exception of (a) their agents, representatives, counsel
and accountants, affiliates, successors and assigns, potential investors,
lenders acquirers or acquirees, provided that the foregoing shall have been
placed under obligations of confidentiality, substantially similar to those
contained herein; (b) the Landlord and (c) to the extent required to be
disclosed by law or by the order of the court or government agency which has
jurisdiction over such party. If any person otherwise within the exception to
clause (a) above shall refuse to be placed under obligation of confidentiality,
and such refusal is customary within such person's trade or business, then the
party affected shall so notify the other, with relevant particulars, and the
parties agree to confer and stipulate conditions of disclosure such that the
requested party shall not unreasonably withhold, condition or delay consent to
the disclosure of the minimum amount of information to which this section
relates as may be necessary for the person refusing confidentiality to perform
his or her customary business functions, and for the party granting consent to
monitor disclosures of such information.

                                       14
<Page>

Neither Tenant nor Subtenant shall issue any press release or other public
statement or otherwise make known to the media the terms of this Sublease
Agreement or any negotiations in connection herewith, without the prior written
consent of the other party. Each party acknowledges and agrees that the other
party cannot and will not be responsible for the actions of third parties who
may choose to advertise or make a public statement regarding this transaction.

     27.  The parties warrant and represent to each other that neither has dealt
with any broker or other contingently compensable third party in connection with
this Sublease other than Richards Barry Joyce & Partners and Grubb & Ellis
(collectively, the "Broker") and, each party agrees to indemnify the other
against any other brokerage claims against the indemnitee arising by virtue of
this Sublease. Tenant agrees to pay any brokerage commissions due and owing to
the Broker arising by virtue of this Sublease, including a fee to Grubb & Ellis
not to exceed $1.00 per rentable square foot of the Premises per year of the
Term, and a reasonable fair market brokerage fee for any renewal or expansion in
which said broker has actively participated on behalf of Subtenant.

                        CALCULATION OF FAIR RENTAL VALUE

(1)  Tenant shall notify Subtenant in writing of Tenant's proposed Base Rent for
the Premises during the first year of the Extension Term no later than ten
months before the expiration of the initial Term.

(2)  If Subtenant does not accept Tenant's proposal as previously delivered,
then at the time of its election to extend the Term, Subtenant shall notify
Tenant of its estimate of Fair Rental Value for the Premises. During the thirty
days after Subtenant gives such notice, Tenant and Subtenant shall attempt to
agree as to the Fair Rental Value for the Premises as of the beginning of the
fifth year of the initial Term. Within fourteen (14) days after the expiration
of such 30-day period, Tenant shall give written notice to Subtenant stating
that Tenant either (i) accepts Subtenant's estimate of Fair Rental Value, or
(ii) elects to submit the determination of Fair Rental Value to appraisal in
accordance with the following provisions.

(3)  Within ten (10) days after Subtenant receives Tenant's notice of its
election to submit the determination of Fair Rental Value to appraisal, Tenant
and Subtenant shall each choose an appraiser. If either party fails to choose an
appraiser within such time, the Fair Rental Value will be determined by the
appraiser chosen by the other party. All appraisers shall be impartial
individuals having at least five (5) years experience in appraising commercial
real estate in the vicinity of the Premises. "Fair Rental Value" shall be
determined on the basis of then current rentals of comparable quality office
space in the commercial/industrial market area located within a ten (10) mile
radius of the Building, taking into account, without limitation, such
considerations as size, location, age, construction, economic conditions,
concessions and inducements to rent, and build-out allowances. Each appraiser
shall prepare an appraisal report and submit it to the party that hired it
within forty-five (45) days after Subtenant's receipt of such notice from
Tenant. Each party shall promptly deliver a copy of its appraiser's report to
the other party.

(4)  If the two appraisals of Fair Rental Value are within fifteen percent (15%)
of each other, then the average of the two appraisals shall be the Fair Rental
Value for the Premises. If the two appraisals are not within fifteen percent
(15%) of each other, then within seven (7) days after receipt by Tenant and
Subtenant of both appraisal reports, the appraisers selected by Tenant and
Subtenant shall agree on a third appraiser to determine Fair Rental Value. If
the appraisers are unable to agree on the third appraiser within such time, then
the third appraiser shall be chosen by the President of the County Real Estate
Board for the county in which the premises are located. The third appraiser
shall not perform a third appraisal, but shall, within thirty (30) days after
his or her designation, select one of the two appraisals already performed as
his or her determination of the Fair Rental Value. The decision of the third
appraiser shall be conclusive, and shall be the Fair Rental Value for the
Premises.

(5)  Each party shall pay the costs of its appraiser and one-half of the cost of
the third appraiser.

(6)  After the Fair Rental Value has been determined in accordance with this
Section (either by Tenant's acceptance of Subtenant's calculation of Fair Rental
Value or the determination of

                                       18

the Fair Rental Value through the appraisal process), Subtenant shall have
fourteen (14) days from said date to determine whether to rescind its exercise
of the applicable Extension Option.

<Page>

to Tenant (except with respect to matters covered by subsection (i) of this
Section), and without any liability to Tenant in any respect, Landlord may:

               (1) establish in writing and enforce reasonable rules and
          regulations concerning the maintenance, management, use, and operation
          of the Common Areas;

               (2) close off any of the Common Areas to any extent required in
          the opinion of Landlord and its counsel to prevent a dedication of any
          of the Common Areas or the accrual of any rights by any person or the
          public to the Common Areas, so long as such closure does not deprive
          Tenant of the substantial benefit and enjoyment of the Premises;

               (3) temporarily close any of the Common Areas for maintenance,
          alteration, or improvement purposes with reasonable prior notice;

               (4) select, appoint, or contract with any person for the purpose

               (5) change the size, use, shape, or nature of any Common Areas
          with reasonable prior notice, so long as such change does not deprive
          Tenant of the substantial benefit and enjoyment of the Premises. So
          long as Tenant is not thus deprived of the material use and benefit of
          the Premises, Landlord may change the arrangement or location of, or
          both, or regulate or eliminate the use of any concourse, parking
          structure, or any elevators, stairs, toilets, roadways, plazas,
          landscaping or other public conveniences in the Development, without
          incurring any liability to Tenant or entitling Tenant to abatement of
          rent, and such action will not constitute an actual or constructive
          eviction of Tenant; and

               (6) erect one or more additional buildings or expand buildings or
          the parking structure on the Common Areas, expand the Building or
          other structures to cover a portion of the Common Areas, convert
          Common Areas to a portion of the Building or other structures, or
          convert any portion of the Building or other structures to Common
          Areas, so long as any such change does not deprive Tenant of the
          substantial benefit and enjoyment of the Premises. If any changes in
          the size or use of the Building are made, Landlord will make an
          appropriate adjustment in the rentable area of the Building and in
          Tenant's Proportionate Share of Expenses and Common Area Charges
          payable pursuant to Article 4 of this Lease.

          (d) "Common Area Charges" shall mean the amounts paid by Landlord in

under that certain Master Declaration of Covenants, Conditions, Restrictions and
Easements for Pointe O'Hare (the "Master Declaration") dated October 5, 2001, as

operating agreement or other such agreement providing for the joint or shared

                                       4
<Page>

operation of portions of the Development and adjoining property. Common Area
Charges shall include, but not be limited to, all costs and expenses incurred
for: restriping, resurfacing, and sealing parking and roadway areas, painting,
cleaning, maintenance of structural elements, snow and ice removal and for the

structural parts of buildings; water, power and sewerage charges; premiums for
all insurance carried by Landlord in connection with the Common Areas, whether
or not Landlord is required to provide any such insurance by this Lease; wages
(including employee benefits); salaries (including employee benefits) of any
employee directly and actually performing services in connection with the Common
Areas; unemployment taxes; social security taxes; the cost (including sales and
use taxes) of material, equipment, supplies and services purchased for
maintenance and repair of the Common Areas; fees for required licenses and

the Metropolitan Water Reclamation District TIF Service Fee allocated to Parcel
One; operation of loudspeakers and any other equipment supplying entertainment

depreciation of movable equipment used in the operation, maintenance or repair
of the Common Areas including equipment incorporated in the fitness center
("Fitness Equipment"), but in any such event without duplication as to
depreciation charges on any such movable equipment, but as to the rental of such
equipment only if rental thereof will, in the judgment of Landlord, be less
expensive than depreciation on owned equipment, provided however notwithstanding
the foregoing, the entire cost of rental, if any, of the Fitness Equipment shall
be included in Common Area Charges notwithstanding any comparison to
depreciation charges; and all other similar direct costs and expenses properly
chargeable to ownership, operation, maintenance or repair of the Common Areas.
Notwithstanding the foregoing, there shall be excluded from Common Area Charges:

(vii) to the extent that such receipts reduce Common Area Charges, all sums
received by Landlord pursuant to Sections 15.01(b), 15.03(b) and 15.04 of the
Master Declaration; and (viii) overhead. The cost of any capital improvements to
the Common Areas made after the date of this Lease which are intended to reduce
Common Area Charges or which are required under any governmental laws,
regulations or ordinances which were not applicable to the Common Areas at the
time they were constructed, amortized over such reasonable period as Landlord
shall determine, together with interest on the unamortized cost of any such
improvement (at the prevailing construction loan rate available to Landlord on
the date the cost of such improvement was incurred) shall be included in Common
Area Charges. If any item of Common Area Charges, although paid or incurred in
one year, relates to more than one calendar year, at the option of Landlord,
such item may be allocated proportionately among such related calendar years. At
such time, if any, as Landlord constructs Building II, Landlord shall allocate
the Common Area Charges for Parcel One between Building I and Building II as
Landlord

                                       5
<Page>

determines in its sole discretion is appropriate and proportional.

not include any of the costs and expenses described in Attachment A hereto.

limitation, the cost of security and security devices and systems; snow, ice and
trash removal; cleaning and sweeping; planting and replacing decorations,
flowers and landscaping; maintenance, repair and replacement of utility systems,

subsection (i) of this clause (e), and not to the extent replacement of any item
would constitute a capital improvement or a capital expenditure which is

                                       6

          Notwithstanding anything contained in this clause (e) to the contrary:

               (1) The cost of any capital improvements to the Building made
          after the date of this Lease which are intended to reduce Expenses or
          which are required under any governmental laws, regulations or
          ordinances which were not applicable to the Building at the time it
          was constructed, amortized over such reasonable period as Landlord
          shall determine, together with interest on the unamortized cost of any
          such improvement (at the prevailing construction loan rate available
          to Landlord on the date the cost of such improvement was incurred)
          shall be included in Expenses.

               (2) If the Building is not at least ninety-five percent (95%)
          occupied by tenants during all or a portion of any Adjustment Year, or
          if during all or a portion of any Adjustment Year Landlord is not
          furnishing to any tenant or tenants any particular service, the cost
          of which, if furnished by Landlord, would be included in Expenses,
          then Landlord may elect to make an adjustment for such year of
          Expenses and the amounts thereof which may vary depending upon the
          occupancy level of the Building or the number of tenants using the
          service. Any such adjustments shall be deemed costs and expenses paid
          or incurred by Landlord and included in Expenses for such year, as if
          the Building had been ninety-five percent (95%) occupied during the
          entire Adjustment Year, Landlord had furnished such service at its
          expense to all tenants for the entire Adjustment Year and Landlord had
          paid or incurred such costs and expenses for such year.

               (3) If any item of Expenses, although paid or incurred in one
          year, relates to more than one calendar year, at the option of
          Landlord, such item may be allocated among such related calendar
          years.

          (f) "Taxes" shall mean real estate taxes, general or special
assessments, sewer and water rents (to the extent such rents are not included in
the Common Areas Charges or separately paid by Tenant), rates and charges,
transit and transit district taxes, taxes based upon the receipt of rent, and
any other federal, state or local governmental charge, whether general, special,
ordinary or extraordinary (but not including income or franchise taxes or any
other taxes imposed upon or measured by Landlord's income or profits, except as
provided herein), which may now or hereafter be due and payable during the Term
without regard to when such taxes are levied, assessed or imposed against Parcel
One, the Common Area or any portion thereof. For example, the Taxes includable
for calendar year 2003 shall be those levied and assessed in 2002, though
payable in 2003. At such time, if any, Landlord constructs Building II, Landlord
shall allocate the Taxes for Parcel One between Building I and Building II as
Landlord determines in its sole discretion is appropriate and proportional.
Tenant acknowledges Landlord shall be under no obligation to construct
Building II.

          Notwithstanding anything contained in this clause (f) to the contrary:

               (1) If at any time the method of taxation then prevailing is
          altered so that any new or additional tax, assessment, levy,
          imposition or charge or any part thereof is imposed upon Landlord in
          place or partly in place of any such Taxes or contemplated increase
          therein, or in addition to Taxes, and is measured by or is based in
          whole or in part upon the Real Property or the rents or other income
          therefrom, then all such new

                                       7
<Page>

          taxes, assessments, levies, impositions or charges or part thereof, to
          the extent that they are so measured or based, shall be included in
          Taxes levied, assessed or imposed against the Real Property to the
          extent that such items would be payable if the Real Property was the
          only property of Landlord subject thereto and the income received by
          Landlord from the Real Property was the only income of Landlord,

               (2) Notwithstanding the year for which any such taxes or
          assessments are levied, (A) in the case of taxes or special
          assessments which may be paid in installments, the amount of each
          installment, plus any interest payable thereon, paid during a calendar
          year shall be included in Taxes for that year and (B) if any taxes or
          assessments payable during any calendar year shall be computed with
          respect to a period in excess of twelve (12) calendar months, then
          taxes or assessments applicable to the excess period shall be included
          in Taxes for that year.

               (3) Taxes shall also include any personal property taxes
          (attributable to the calendar year in which paid) imposed upon the
          furniture, fixtures, machinery, equipment, apparatus, systems and
          appurtenances which are components of the Development or the Common
          Areas.

               (4) If the Building is not at least ninety-five percent (95%)
          occupied by tenants during all or a portion of any Adjustment Year,
          then Landlord may elect to make an appropriate adjustment for such
          year of components of Taxes which may vary depending upon the
          occupancy level of the Building such that tenants then occupying space
          in the Building will pay their respective proportionate share of the
          amount of such Taxes which would have been incurred if the Building
          had been ninety five percent (95%) occupied during the entire
          Adjustment Year and Landlord had paid or incurred such Taxes for such
          year. Any such adjustments shall also be deemed Taxes levied or
          assessed against the Building and included in Taxes for such year.

          (g) "Rentable Area of the Building" shall mean the sum of the rentable
areas on all floors of the Building, which has been computed by Landlord's
architect measuring the floors in accordance with the BOMA 1996 standards. The
Rentable Area of the Building, as so computed and for all purposes herein, is
Two Hundred Sixty-Two Thousand Nine Hundred Ninety-Four (262,994) rentable
square feet.

          (h) "Rentable Area of the Premises" has been computed by Landlord's
architect in accordance with the BOMA 1996 standards. The Rentable Area of the
Premises, as so computed and for all purposes herein, is agreed to be Seventeen
Thousand One Hundred Ninety-One (17,191) rentable square feet.

          (i) "Tenant's Proportionate Share" shall mean six and 54/100 percent
(6.54%), which is the percentage obtained by dividing the Rentable Area of the
Premises by the Rentable Area of the Building.

          (j) "Rent Adjustments" shall mean all amounts determined pursuant to
this Article, including all amounts payable by Tenant to Landlord on account
thereof.

                                       8
<Page>

          4.03. COMPUTATION OF RENT ADJUSTMENTS. Tenant shall pay Rent
Adjustments for each Adjustment Year determined as hereinafter set forth. Rent
Adjustments payable by Tenant with respect to each Adjustment Year during which
an Adjustment Date falls shall include the following amounts:

          (a) the product of Tenant's Proportionate Share multiplied by the
amount of Taxes for such Adjustment Year (said product being hereinafter
referred to as the "Tax Adjustment"); plus

          (b) the product of Tenant's Proportionate Share multiplied by the
amount of Expenses for such Adjustment Year (said product being hereinafter
referred to as the "Expense Adjustment"); plus

          (c) the product of Tenant's Proportionate Share of Common Area Charges
multiplied by the amount of Common Area Charges for such Adjustment Year (said
product being hereinafter referred to as the "Common Area Adjustment").

          Tenant agrees and acknowledges that Landlord has made no
representation, warranty or guaranty relating to the amount of Taxes, Common
Area Charges or Expenses. Tenant has had an opportunity to consult with Landlord
with respect to the Taxes, Expenses and Common Area Charges, but has not relied
upon any statements or representations of Landlord or of any agent or affiliate
of Landlord in regard thereto in executing this Lease and in agreeing to perform
the terms and covenants hereof and shall make no claim against Landlord based
thereon.

     4.04. PAYMENTS OF RENT ADJUSTMENTS PROJECTIONS. Tenant shall pay Rent
Adjustments to Landlord in the manner hereinafter provided:

     Tax Adjustment, Common Area Adjustment and Expense Adjustment. Tenant shall
make payments on account of Tax Adjustment, Common Area Adjustment and Expense
Adjustment (the aggregate of such payments with respect to any Adjustment Year
being hereinafter referred to as the "Rent Adjustment Deposit") as follows:

               (1) Prior to each Adjustment Date and from time to time during
          the Adjustment Year in which such Adjustment Date falls, Landlord may
          deliver to Tenant a written notice or notices (each such notice being
          hereinafter referred to as a "Projection Notice") setting forth (A)
          Landlord's reasonable estimates, forecasts or projections
          (collectively, the "Projections") of any or all of Taxes, Common Area
          Charges and Expenses for such Adjustment Year and (B) Tenants Rent
          Adjustment Deposits with respect to the Tax Adjustment, Common Area
          Adjustment and Expense Adjustment components of Rent Adjustments for
          such Adjustment Year based upon the Projections. Landlord's budgets of
          Expenses, Common Area Charges and the Projections based thereon may
          assume ninety-five percent (95%) occupancy of the Building, and that
          Landlord will furnish all services included in Expenses and Common
          Area Charges to all tenants of the Building and authorized users of
          the Common Areas.

               (2) Tenant shall commence payments of monthly installments of
          Rent Adjustment Deposits on the first day of the first calendar month
          during the Term following Landlord's delivery of the first Projection
          Notice hereunder. On such date, and

                                       9
<Page>

          on or before the first day of each calendar month thereafter of the
          Adjustment Year covered by such Projection Notice, Tenant shall pay to
          Landlord one-twelfth (1/12) of the Rent Adjustment Deposits shown in
          the Projection Notice. Within thirty, (30) days following Landlord's
          delivery of a Projection Notice for an Adjustment Year in progress,
          Tenant also shall pay Landlord a lump sum equal to the Rent Adjustment
          Deposits shown in the Projection Notice less the sum of (A) any
          previous payments on account of Rent Adjustment Deposits made with
          respect to such Adjustment Year and (B) monthly installments on
          account of Rent Adjustment Deposits due for the remainder of such
          Adjustment Year. Until such time as Landlord furnishes a Projection
          Notice for an Adjustment Year, Tenant shall continue to pay monthly
          installments of Rent Adjustment Deposits in the amount shown by the
          most recent Projection Notice or, if the Tax and Expense Adjustment
          for the Adjustment Year covered by such Projection Notice has been
          determined, one-twelfth (1/12) of such Tax and Expense Adjustment,
          whichever is greater.

     4.05. READJUSTMENTS. The following readjustments shall be made by Landlord
and Tenant for Expense Adjustment, Common Area Adjustment and Tax Adjustment:

          (a) Following the end of each Adjustment Year and after Landlord has
determined the actual amount of Expenses to be used in calculating the Expense
Adjustment and the actual amount of Common Area Charges to be used in the
calculating the Common Area Adjustment for such Adjustment Year, Landlord shall
notify Tenant in writing (any such notice hereinafter referred to as "Landlord's
Expense and Common Area Statement") of such Expenses and Common Area Charges and
Tenant's Expense Adjustment and Common Area Adjustment for such Adjustment Year.
If the Expense and Common Area Adjustment owed for such Adjustment Year exceeds
the Expense and Common Area Adjustment component of the Rent Adjustment Deposits
paid by Tenant during such Adjustment Year, then Tenant, within thirty (30) days
after the date of Landlord's Expense and Common Area Statement, shall pay to
Landlord an amount equal to the excess of the Expense and Common Area Adjustment
over the Expense and Common Area Adjustment component of the Rent Adjustment
Deposits paid by Tenant during such Adjustment Year. If the Expense and Common
Area Adjustment component of the Rent Adjustment Deposits paid by Tenant during
such Adjustment Year exceeds the Expense and Common Area Adjustment owed for
such Adjustment Year, then Landlord shall credit such excess to Rent payable
after the date of Landlord's Expense and Common Area Statement, or, at its
option, may credit such excess to any Rent theretofore due and owing as of such
date, until such excess has been exhausted; provided however, any such amount of
excess left after crediting shall promptly be paid to Tenant. If this Lease
expires or is terminated prior to full application of such excess, Landlord
shall promptly pay to Tenant the balance thereof not theretofore applied against
Rent and not reasonably required for payment of Rent for the Adjustment Year in
which this Lease expires, subject to Tenant's obligations under Section 4.08
hereof, provided Tenant has vacated the Premises and otherwise has surrendered
the Premises to Landlord in accordance with this Lease and Tenant is not then in
default under this Lease.

          (b) Following the end of each Adjustment Year and after Landlord has
determined the actual amount of Taxes to be used in calculating the Tax
Adjustment for such Adjustment Year, Landlord shall notify Tenant in writing
(any such notice hereinafter referred to as "Landlord's Tax Statement") of such
Taxes for such Adjustment Year. If the Tax Adjustment

                                       10
<Page>

owed for such Adjustment Year exceeds the Tax Adjustment component of the Rent
Adjustment Deposits paid by Tenant during such Adjustment Year, then Tenant,
within thirty (30) days after the date of Landlord's Tax Statement, shall pay to
Landlord an amount equal to the excess of the Tax Adjustment over the Tax
Adjustment component of the Rent Adjustment Deposits paid by Tenant during such
Adjustment Year. If the Tax Adjustment component of the Rent Adjustment Deposits
paid by Tenant during such Adjustment Year exceeds the Tax Adjustment owed for
such Adjustment Year, then Landlord shall credit such excess to Rent payable
after the date of Landlord's Tax Statement, or, at its option, may credit such
excess to any Rent theretofore due and owing, until such excess has been
exhausted. If this Lease expires or is terminated prior to full application of
such excess, Landlord shall promptly pay to Tenant the balance thereof not
theretofore applied against Rent and not reasonably required for payment of Rent
for the Adjustment Year in which this Lease expires, subject to Tenants
obligations under Section 4.08 hereof; provided Tenant has vacated the Premises
and otherwise has surrendered the Premises to Landlord in accordance with this
Lease and Tenant is not then in default under this Lease.

     4.06. BOOKS AND RECORDS. Landlord shall maintain books and records showing
Taxes, Common Area Charges and Expenses in accordance with sound mounting and
management practices. Tenant or its representative shall have the right to
examine Landlord's books and records showing Taxes, Common Area Charges and
Expenses upon reasonable prior notice and during normal business hours at any
time within thirty (30) days following the furnishing by Landlord to Tenant of
Landlord's Expense and Common Area Statement or Landlord's Tax Statement, as the
case may be, provided for in Section 4.05. Unless Tenant takes written exception
to any item within thirty (30) days after the furnishing of Landlord's Expense
and Common Area Statement or Landlord's Tax Statement, as the case may be,
containing such item, such Landlord's Statement shall be considered final and
accepted by Tenant.

     4.07. AUDIT PROCEDURES. If Tenant notifies Landlord within such thirty (30)
day period that Tenant disputes any specific item or items in any Landlord's
Expense and Common Area Statement or Landlord's Tax Statement, as the case may
be, and such dispute is not resolved between Landlord and Tenant within thirty
(30) days after the date such notice is given by Tenant, either party, during
the fifteen (15) day period following the expiration of the thirty (30) day
period commencing on the date such notice is given, may refer such disputed item
or items for determination to an independent certified public accountant
selected by such party and approved by the other party, which approval shall not
be withheld unreasonably, and the determination of such accountant shall be
final, conclusive and binding upon Landlord and Tenant. Tenant agrees to pay all
costs involved in such determination except in the case of Tax Adjustment and
Expense and Common Area Adjustment for any Adjustment Year where it is
determined that Landlord has overcharged Tenant for Tax Adjustment and Expense
and Common Area Adjustment for such Adjustment Year by more than five percent
(5%), in which case Landlord shall pay such costs.

     4.08. PRORATION AND SURVIVAL. With respect to any Adjustment Year which
does not fall entirely within the Term, Tenant shall be obligated to pay as
Expense and Common Area Adjustment and Tax Adjustment for such Adjustment Year
only a pro rata share of Expense and Common Area Adjustment and Tax Adjustment
as hereinabove determined, based upon the number of days of the Term falling
within the Adjustment Year. Following expiration or termination of this Lease,
Tenant shall pay any Rent Adjustments due to Landlord within thirty

                                       11
<Page>

(30) days after the date of each Landlord's Statement sent to Tenant. Without
limitation of other Obligations of Tenant which shall survive the expiration of
the Term, the obligation of Tenant to pay Rent Adjustments provided for in this
Article accruing during the Term shall survive the expiration or termination of
this Lease.

     4.09. NO DECREASE IN BASE RENT. In no event shall any Rent Adjustments
result in a decrease of Base Rent payable hereunder.

     4.10. ADDITIONAL RENT. All amounts payable by Tenant as or on account of
Rent Adjustments shall be deemed to be additional rent becoming due under this
Lease. The failure to timely pay Rent Adjustments shall permit Landlord to
exercise any and all of its rights and remedies herein provided for failure to
pay Base Rent.

     4.11. RENT ADJUSTMENTS DURING YEARS 1 AND 2 OF LEASE. Tenant acknowledges,
notwithstanding the Base Rent abatement applicable to Lease Years 1 and 2
hereof, Tenant remain responsible for Rent Adjustments applicable to Lease Years
1 and 2 hereof.

                                   ARTICLE 5

                                 USE OF PREMISES

     Tenant shall use and occupy the Premises for general office purposes and
for no other use or purpose, whether primary, ancillary or otherwise, provided
however Tenant shall not be entitled to use the Premises for purposes of a
commercial or retail bank, savings and loan, or credit union. Tenant shall not
use or occupy the Premises or permit the use and occupancy of the Premises or
permit the use and occupancy of the Premises for any purpose or in any manner
which (i) is unlawful or in violation of any applicable legal or governmental
requirement, ordinance or rule; (ii) may be dangerous to persons or property,
(iii) may invalidate or increase the amount of premiums for any policy of
insurance affecting the Development if Tenant continues any such action or
omission after notice from Landlord such action or omission would invalidate or
increase the amount of premiums for any policy of insurance affecting the
Development, or (iv) may create a nuisance or disturb any other tenant of the
Building or injure the reputation of the Building.

                                   ARTICLE 6

                                    SERVICES

     6.01. SERVICES PROVIDED. Landlord shall use commercially reasonable efforts
to furnish or caused to be furnished the following services, the costs of which
shall, in all instances, be deemed Expenses (except to the extent paid entirely
by Tenant, as hereinafter provided):

          (a) Air conditioning and heating when necessary to provide a
temperature condition required, in Landlord's judgment, for comfortable
occupancy of the Premises under normal business operations, daily from 7: 30
a.m. to 7:00 p.m. (Saturdays from 8:00 a.m. to 1:00 p.m.), Sundays and holidays
excepted. Whenever Tenant's use or occupation of the Premises

                                       12
<Page>

exceeds the design loads for the system providing heating and air conditioning,
or lighting or heat-generating machines or equipment which cumulatively exceed
such design loads are used by Tenant in the Premises, which affect the
temperature otherwise maintained by the heating, ventilating and air
conditioning system in the Premises or Building, Landlord may temper such excess
loads by installing supplementary heat or air conditioning units in the Premises
or elsewhere where necessary, and the cost of such units and the expense of
installation, including, without limitation, the cost of preparing working
drawings and specifications, shall be paid by Tenant as additional rent within
ten (10) days after Landlord's demand therefor. The expense resulting from the
operation and maintenance of any such supplementary heat or air conditioning
units shall be paid by Tenant to Landlord as additional rent at rates fixed by
Landlord. Landlord's agreements hereunder are subject to voluntary and mandatory
presidential and governmental restrictions on energy use.

          (b) Domestic water in common with other tenants for drinking, lavatory
and toilet purposes drawn through fixtures installed by Landlord, or by Tenant
in the Premises with Landlord's written consent, and hot water in common with
other tenants for lavatory purposes from regular Building supply. Tenant shall
pay Landlord as additional rent at Landlord's scheduled rates for domestic water
and hot water furnished for any other purpose. Tenant shall not waste or permit
the waste of water.

          (c) Janitorial and cleaning service nightly in and about the Premises,
Saturdays, Sundays and holidays excepted. Tenant shall not provide or use any
other janitorial or cleaning services without Landlord's consent, and then only
subject to supervision of Landlord and at Tenant's sole responsibility and by a
janitor, cleaning contractor or employees at all times satisfactory to Landlord.

          (d) Passenger elevator service in common with Landlord and other
persons, daily from 7:00 a.m. to 7:00 p.m. (Saturdays from 8:00 a.m. to 1:00
p.m.), Sundays and holidays excepted, and freight elevator service in common
with Landlord and other persons, daily from 8:00 a.m. to 5:00 p.m., Saturdays,
Sundays and holidays excepted. Such normal elevator service, passenger or
freight, if furnished at other times, shall be optional with Landlord and shall
never be deemed a continuing obligation. Landlord, however, shall provide
limited passenger elevator service daily at all times when such normal passenger
service is not furnished.

          (e) Electricity shall not be furnished by Landlord, but shall be
furnished by an electric utility company serving the area in which the Building
is located. Landlord shall permit Tenant to receive such service directly from
such utility company at Tenant's cost, and shall permit Landlord's wire and
conduits, to the extent available, suitable, safe and capable, to be used for
such purposes. Tenant shall make all necessary arrangements with the utility
company for metering of and paying for electric current furnished by it to
Tenant and Tenant shall pay for all charges for installation of electric meters
and electric current consumed on the Premises during Tenant's occupancy. The
electricity used during the performance of janitorial service, the making of
alterations or repairs in the Premises, and for the operation of the Building's
air conditioning system for Tenant at times other than as provided in
subparagraph (a) hereof, or the operation of any special air conditioning
systems which may be required for data processing equipment or for other special
equipment or machinery installed by Tenant, shall be paid by Tenant. Tenant
shall make no alterations or additions to the electric equipment or appliances

                                       13
<Page>

without the prior written consent of Landlord in each instance. Tenant also
agrees to purchase from Landlord or its agents all lamps, bulbs, ballasts and
starters used in the Premises during the Term, which materials shall be sold to
Tenant by Landlord at Landlord's cost. Tenant covenants and agrees that at all
times its use of electric current shall never exceed the capacity of the feeders
to the Building or the risers or wiring installed thereon.

          (f) Landlord may provide such extra or additional services as it is
reasonably possible for Landlord to provide, and as Tenant may request from time
to time, within a reasonable period after the time such extra or additional
services are requested. Tenant shall pay, for such extra or additional services,
an amount equal to one hundred ten percent (110%) of Landlord's actual cost
reasonably incurred in providing such additional services, such amount to be
considered additional rent hereunder. All charges for such extra or additional
services shall be due and payable at the same time as the installment of Base
Rent with which they are billed, or if billed separately, shall be due and
payable within thirty (30) days after such billing. Any such billings for extra
or additional services shall include an itemization of the extra or additional
services rendered, and the charge for each such service.

     6.02. FAILURE TO PAY FOR SERVICES. Failure by Tenant to pay Landlord's
proper charges for water or other services promptly shall give Landlord, upon
not less than ten (10) days' notice, the right to discontinue furnishing the
services, and no such discontinuance shall be deemed an eviction or disturbance
of Tenant's use of the Premises or render Landlord liable for damages or relieve
Tenant from performance of Tenant's obligations under this Lease.

     6.03. FAILURE TO FURNISH SERVICES. Except as otherwise specifically
provided in this Lease, Tenant agrees that Landlord and its agents shall not be
liable in damages, by abatement of Rent or otherwise, for failure to furnish or
for delay in furnishing any service when such failure or delay is occasioned, in
whole or in part, by repairs, renewals or improvements, by any strike, lockout
or other labor trouble, by inability to secure electricity, gas, water or other
fuel at the Building after reasonable effort to do so, by any accident or
casualty whatsoever, by the act or default of Tenant or other parties, or by any
cause beyond the reasonable control of Landlord; and such failures or delays
shall never be deemed an eviction or disturbance of Tenant's use or possession
of the Premises or relieve Tenant from paying Rent or performing any of its
obligations under this Lease, provided, however, Landlord shall use commercially
reasonable efforts to restore any interruption of such services to the extent
Tenant advises Landlord of such interruption or such interruption is otherwise
known by Landlord.

     6.04. REGULATIONS REGARDING UTILITIES SERVICES. Tenant agrees to cooperate
fully, at all times, with Landlord in abiding by all reasonable regulations and
requirements which Landlord may prescribe for the proper functioning and
protection of all utilities and services reasonably necessary for the operation
of the Premises and the Building. Throughout the Term of this Lease, Landlord
shall have fine access to any and all mechanical installations, and Tenant
agrees that there shall be no construction of partitions or other obstructions
which might interfere with access to or the moving or servicing of equipment to
or from the enclosures containing said installations. Tenant further agrees that
neither Tenant nor its employees, agents, licensees, invitees or contractors
shall at any time tamper with, adjust or otherwise in any manner affect
Landlord's mechanical installations.

                                   ARTICLE 7

                         CONDITION AND CARE OF PREMISES

     Tenant's taking possession of the Premises or any portion thereof pursuant
to the terms of the Work Letter for construction of the Tenant Improvements
shall be conclusive evidence against Tenant that the portion of the Premises
taken possession of was then in satisfactory condition. No promises of Landlord
to alter, remodel, improve, repair, decorate or clean the Premises or any part
thereof have been made, and no representation respecting the condition of the
Premises, the Building or Parcel One, has been made to Tenant by or on behalf of
Landlord except to the extent expressly set forth herein. Except for any damage
resulting from any wanton or negligent act of Landlord or its employees and
agents, and subject to the provisions of Article 15 hereof, Tenant, at its own
expense, shall keep the Premises in good repair and tenantable condition and
shall promptly and adequately repair all damage to the Premises caused by Tenant
or any of its employees, contractors, agents, invitees or licensees, including
replacing or repairing all damaged or broken glass, fixtures and appurtenances
resulting from any such damage, under the supervision and with the approval of
Landlord and within any reasonable period of time specified by Landlord. If
Tenant does not do so promptly and adequately, Landlord may, but need not, make
such repairs and replacements and Tenant shall pay Landlord the cost thereof on
demand.

                                   ARTICLE 8

                               RETURN OF PREMISES

     8.01. SURRENDER OF POSSESSION. At the termination of this Lease by lapse of
time or otherwise or upon termination of Tenant's right of possession without
termination of this Lease, Tenant shall surrender possession of the Premises to
Landlord and deliver all keys to the Premises to Landlord and make known to
Landlord the combination of all locks or vaults then remaining in the Premises,
and, subject to the following paragraph, shall return the Premises and all
equipment and fixtures of Landlord therein to Landlord in as good condition as
when Tenant originally took occupancy of the Premises subsequent to completion
of construction of the Tenant Improvements contemplated by the Work Letter,
ordinary wear, loss or damage by fire or other casualty not caused by Tenant,
and damage resulting from the act of Landlord or its employees and agents
excepted, failing which Landlord may restore the Premises and such equipment and
fixtures to such condition and Tenant shall pay the cost thereof to Landlord on
demand.

     8.02. INSTALLATIONS AND ADDITIONS. All installations, additions,
partitions, hardware, light fixtures, non-trade fixtures and improvements,
whether temporary or permanent, except movable furniture and equipment belonging
to Tenant, in or upon the Premises, whether placed there by Tenant or Landlord,
shall be Landlord's property and, upon termination of this Lease by lapse of
time or otherwise, or of Tenant's right of possession without termination of
this Lease, shall remain upon the Premises, all without compensation, allowance
or credit to Tenant; provided, however, solely with respect to specific
improvements Landlord has previously advised Tenant pursuant to the terms of
this Paragraph that removal of such improvements may be required and

                                       15
<Page>

Landlord so directs removal by notice, Tenant, at Tenant's sole cost and
expense, shall promptly remove such of the installations, additions, partitions,
hardware, light fixtures, non trade fixtures and improvements placed in the
Premises by Tenant as are designated in such notice and repair any damage to the
Premises caused by such removal, failing which Landlord may remove the same and
repair the Premises and Tenant shall pay the cost thereof to Landlord on demand.
At the sole option of Landlord, Tenant shall leave in place any floor covering
without compensation to Tenant, or Tenant shall remove any floor covering and
shall remove all fastenings, paper, glue, bases or other vestiges and restore
the floor surface to its previous condition, or shall pay to Landlord upon
demand the cost for restoring the floor surface to such condition.
Notwithstanding the foregoing, Tenant shall, subject to the terms of
Subparagraph 29.16 hereof, have no obligation to remove any improvements
constructed by Tenant pursuant to the terms of Exhibit D hereto to the extent
same are customary office improvements or, if not customary office improvements,
Landlord has not advised Tenant, in writing at the time of Landlord's approval
of the Working Drawings of Landlord's reservation of the right to require
removal of such improvements upon termination of this Lease.

     8.03. TRADE FIXTURES AND PERSONAL PROPERTY. Tenant shall also remove
Tenants furniture, machinery, safes, trade fixtures and other items of movable
personal property of every kind and description from the Premises and repair any
damage to the Premises caused thereby, such removal and restoration to be
performed prior to the end of the Term or within ten (10) days following
termination of this Lease or Tenant's right of possession, whichever is earlier.
If Tenant fails to remove such items, Landlord may do so, and thereupon the
provisions of Section 17.06 shall apply and Tenant shall pay to Landlord upon
demand the cost of removal and of restoration of the Premises.

     8.04. SURVIVAL. All obligations of Tenant under this Article shall survive
the expiration of the Term or earlier termination of this Lease.

                                   ARTICLE 9

                                  HOLDING OVER

     Tenant shall pay Landlord for each day Tenant retains possession of the
Premises or any part thereof after termination of this Lease, by lapse of time
or otherwise, or of Tenant's right to possession of the Premises, an amount
which is one hundred fifty percent (150%) of the amount of Base Rent and Rent
Adjustments for a day in the last month of the Term, based upon the annual rate
of Base Rent set forth in Section 3.01 and on Rent Adjustments provided for in
Article 4 with respect thereto for the period in which such possession occurs,
calculated as though such period were within the Term, and Tenant shall also pay
all damages, consequential as well as direct, sustained by Landlord by reason of
such retention. In the alternative, if Landlord gives written notice to Tenant
of Landlord's election thereof, such holding over shall constitute a renewal of
this Lease for one year at the annual rate which is one hundred fifty percent of
the Base Rent and Rent Adjustments for the Lease Year immediately preceding such
holding over. Acceptance by Landlord of rent after such termination shall not of
itself constitute a renewal. Nothing contained in this Section shall be
construed or shall operate as a waiver of Landlord's right of reentry or any
other right or remedy of Landlord.

                              RULES AND REGULATIONS

     Tenant agrees to observe and not to interfere with the rights reserved to
Landlord in Article 11 and agrees, for itself, its employees, agents,
contractors, invitees and licensees, to comply with the rules and regulations
set forth in EXHIBIT E attached to this Lease and made a part hereof and such
other rules and regulations as may be adopted by Landlord pursuant to Section
11.01(1) of this Lease. Any violation by Tenant of any of the rules and
regulations contained in Exhibit E or in any Section of this Lease, or as may
hereafter be adopted by Landlord pursuant to Section 11.01(1) of this Lease, may
be restrained; but whether or not so restrained, Tenant acknowledges and agrees
that it shall be and shall remain liable for all damages, loss, costs and
expenses resulting from any violation by Tenant of any of said rules and
regulations. Landlord agrees not to enforce any such rules and regulations
selectively against Tenant.

                                   ARTICLE 11

                           RIGHTS RESERVED TO LANDLORD

     11.01. RIGHTS RESERVED TO LANDLORD. Landlord reserves the following rights,
exercisable without notice and without liability to Tenant for damage or injury
to property, person or business and without effecting an eviction or disturbance
of Tenant's use or possession or giving rise to any claim for setoff or
abatement of Rent or affecting any of Tenant's obligations under this Lease:

          (a) To change the name or street address of the Building;

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

identification sign or lettering for the Premises;

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

          (e) To grant to anyone the exclusive right to conduct any business or
render any service in the Building, or the nonexclusive right to use any
premises in the Building for a use which is the same as or similar to the use
expressly permitted to Tenant by Article 5;

          (f) Subject to reasonable prior notice, to exhibit the Premises at
reasonable hours and to decorate, remodel, repair, alter or otherwise prepare
the Premises for reoccupancy at any time after Tenant vacates or abandons the
Premises;

          (g) To enter the Premises at reasonable hours for reasonable purposes
during normal business hours and thereafter upon reasonable notice (except in an
emergency or

                                       17
<Page>

with respect to janitorial service), including inspection and supplying
janitorial service or other service to be provided to Tenant hereunder;

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

          (i) To regulate access to telephone, electrical and other utility
closets in the Building and to require use of designated contractors for any
work involving access to the same;

          (j) To control and prevent access to common areas and other non
general public areas of the Building pursuant to Exhibit E;

          (k) Provided that reasonable access to the Premises shall be
maintained, the business of Tenant shall not be interfered with unreasonably and
reasonable prior notice had been provided to Tenant, to rearrange, relocate,
enlarge, reduce or change corridors, exits, entrances or other structures or
facilities in or related to the Building or Common Areas and to decorate and, at
its own expense, to make repairs, alterations, additions and improvements,
structural or otherwise, in or to the Building or Common Areas or any part
thereof, and any adjacent building, land, street or alley, including for the
purpose of connection with or entrance into or use of the Building in
conjunction with any adjoining or adjacent building or buildings, now existing
or hereafter constructed, and may for such purposes erect scaffolding and other
structures reasonably required by the character of the work to be performed, and
during such operations may enter upon the Premises and take into and upon or
through any part of the Building, including the Premises, all materials that may
be required to make such repairs, alterations, improvements or additions, and in
that connection, Landlord may temporarily close public entryways, other public
spaces, portions of the parking structure, stairways or corridors in or around
the Building or Common Areas and interrupt or temporarily suspend any services
or facilities agreed to be furnished by Landlord, all without the same
constituting an eviction of Tenant in whole or in part and without abatement of
Rent by reason of loss or interruption of the business of Tenant or otherwise
and without in any manner rendering Landlord liable for damages or relieving
Tenant from performance of Tenant's obligations under this Lease. Landlord, at
its option, may make any repairs, alterations, improvements and additions in and
about the Building and the Premises during ordinary business hours and, if
Tenant desires to have such work done at times other than business hours, Tenant
shall pay all overtime and additional expenses resulting therefrom;

                                       18
<Page>

          (l) From time to time to make and to adopt such reasonable rules and
regulations, in addition to or other than or by way of amendment or modification
of the rules and regulations contained in Exhibit E or other Sections of this
Lease, for the protection and welfare of the Building and Development and its
tenants and occupants, as Landlord may determine and provide to Tenant in
writing, and Tenant agrees to abide by and comply with all such rules and
regulations;

          (m) To relocate any reserved parking spaces, if any, assigned to
Tenant within one (1) floor of their initial location, provided such spaces
shall be located within the same row of parking spaces on the adjacent floor as
they are located on Schedule 2 hereof; and

          (n) To locate, relocate, remove or modify tenant monument signage, if
any, provided to Tenant.

     11.02. USE OF ROOF AND LAND. Landlord specifically excepts and reserves to
itself the use of any roof decks, the exterior portions of the Premises, the
Building Risers, all rights to the land and improvements below the improved
floor level of the Premises, to the improvements and air rights above the
Premises and to the improvements and air rights located outside the demising
walls of the Premises and to such areas within the Premises required for
installation of utility lines and other installations required to serve other
occupants of the Building, including but not limited to any risers and to
maintain and repair same, and no rights with respect thereto are conferred upon
Tenant, unless otherwise specifically provided herein or otherwise granted by
Landlord to Tenant in writing. This Lease does not grant any rights to light or
air.

                                   ARTICLE 12

                                   ALTERATIONS

     Except as otherwise provided in this Lease or attachments hereto, Tenant
shall not make, without the prior written consent of Landlord, which consent
shall not be unreasonably or unduly withheld, any material alterations,
additions or improvements to the Premises. Landlord's decision to refuse such
consent shall be conclusive, and shall not, in any event, be granted if Tenant
is in default hereunder. If Landlord consents to such alterations, additions or
improvements, before commencement of the work or delivery of any materials onto
the Premises or into the Building, Tenant shall furnish to Landlord for approval
plans and specifications, names and addresses of contractors, copies of
contracts, necessary permits and licenses, and instruments of indemnification
against any and all claims, costs, expenses, damages and liabilities which may
arise in connection with such work, all in such form, substance and amount as
may be reasonably satisfactory to Landlord. In addition, prior to commencement
of any such work or delivery of any materials into the Premises, Tenant shall
provide Landlord with appropriate evidence of Tenant's ability to pay for such
work and materials in full, and if requested by Landlord, shall deposit with
Landlord at such time such security for the payment of said work and materials
as Landlord may require. All alterations, additions and improvements shall be
installed in a good, workmanlike manner and only new, highgrade materials shall
be used. All such work shall be done only by contractors or mechanics approved
by Landlord and shall be subject to Landlord's scheduling requirements and
regulations. Tenant further agrees to

                                       19
<Page>

hold Landlord harmless from any and all liabilities of every kind and
description which may arise out of or be connected in any way with said
alterations, additions or improvements. Before commencing any work in connection
with such alterations, additions or improvements, Tenant shall furnish Landlord
with certificates of insurance naming Landlord as an additional insured from all
contractors performing labor or furnishing materials insuring Landlord against
any and all liabilities which may arise out of or be connected in any way with
said alterations, additions or improvements. Tenant shall permit Landlord to
supervise construction operations in connection with the foregoing work if
Landlord requests to do so. Tenant shall pay the cost of all such alterations,
additions and improvements, as well as the cost of decorating and repairing any
damage to the Building, including the Premises, occasioned by such alterations,
additions and improvements, including the cost of labor and materials,
contractors' profits, overhead and general conditions, and a fee to Landlord in
the amount of ten percent (10%) of the cost of such alterations, additions and
improvements. Upon completing any alterations, additions or improvements, Tenant
shall furnish Landlord with contractors' affidavits in form required by law, and
full and final waivers of lien and receipted bills covering all labor and
materials expended and used. All alterations, additions and improvements shall
comply with all insurance requirements and with all city and county ordinances
and regulations and with the requirements of all state and federal statutes and
regulations.

                                   ARTICLE 13

                            ASSIGNMENT AND SUBLETTING

     13.01. ASSIGNMENT AND SUBLETTING. Tenant, without the prior written consent
of Landlord in each instance which, in any event, shall not be granted if Tenant
is in default hereunder, shall not (a) assign, transfer, mortgage, pledge,
hypothecate or encumber or subject to or permit to exist upon or be subjected to
any lien or charge, this Lease or any interest under it, (b) allow to exist or
occur any transfer of or lien upon this Lease or Tenant's interest herein by
operation of law, (c) sublet the Premises or any part thereof, (d) permit the
use or occupancy of the Premises or any part thereof for any purpose not
provided for under Article 5 of this Lease or by anyone other than Tenant and
Tenant's agents and employees, or (e) cause, suffer or permit to occur any
"Change of Control" (as such term is defined in Section 13.08 hereof); provided
however a Change of Control or an assignment to Tenant's successor in interest
by operation of law or pursuant to an acquisition of all or substantially all of
Tenant's assets may occur and shall not require Landlord's consent nor be
subject to the terms of Paragraph 13.04 hereof, so long as the total assets of
such surviving or resulting entity or successor after such Change of Control or
assignment shall be equal to or greater than Tenant's total assets prior to such
Change of Control or assignment. Landlord has the absolute right to withhold its
consent without giving any reason whatsoever, except as herein expressly
provided to the contrary. In no event shall this Lease be assigned or assignable
by voluntary or involuntary bankruptcy proceedings or otherwise, and in no event
shall this Lease or any rights or privileges hereunder be an asset of Tenant
under any bankruptcy, insolvency or reorganization proceedings.

     13.02. RENTALS BASED ON NET INCOME. Without limiting the generality of the
foregoing provisions of this Article, Tenant expressly covenants and agrees not
to enter into any lease, sublease, license, concession or other agreement for
use, occupancy or utilization of the Premises

                                       20
<Page>

which provides for rental or other payment for such use, occupancy or
utilization based in whole or in part on the net income or profits derived by
any person from the property leased, used, occupied or utilized (other than an
amount based upon a fixed percentage or percentages of receipts or sales), and
that any such purported lease, sublease, license, concession or other agreement
shall be absolutely void and ineffective as a conveyance of any right or
interest in the possession, use, occupancy or utilization of any part of the
Premises.

     13.03. TENANT TO REMAIN OBLIGATED. Consent by Landlord to any assignment,
subletting, use, occupancy or transfer shall not operate to relieve Tenant from
any covenant or obligation hereunder except to the extent, if any, expressly
provided for in such consent, or be deemed to be a consent to or relieve Tenant
from obtaining Landlord's consent to any subsequent assignment, transfer, lien,
charge, subletting, use or occupancy. Tenant shall pay all of Landlord's costs,
charges and expenses, including attorneys' fees, incurred in connection with any
assignment, transfer, lien, charge, subletting, use or occupancy made or
requested by Tenant. Tenant agrees that all advertising by Tenant or on Tenant's
behalf with respect to the assignment of this Lease or subletting of space must
be approved in writing by Landlord prior to publication and Tenant shall not
advertise the space for lease at a rental less than that for which comparable
space in the Building is then being offered by Landlord.

     13.04. TENANT'S NOTICE; LANDLORD'S RIGHT TO TERMINATE. Tenant, by notice in
writing, shall advise Landlord of its intention from, on and after a stated date
(which shall not be less than thirty (30) days after the date of Tenant's
notice) to assign this Lease or sublet any part or all of the Premises for the
balance or any part of the Term and shall deliver to Landlord a copy of the
proposed agreement. In the event of such notice from Tenant for assignment of
all of the Premises or a sublet of more than fifty percent (50%) of the
Premises, Landlord shall have the right, to be exercised by giving written
notice to Tenant ("Recapture Notice") within ten (10) days after receipt of
Tenant's notice, to recapture all of the Premises if an assignment or such
sublease space if a sublet of more than fifty percent (50%) of the Premises and
such recapture notice, if given, shall terminate this Lease (a) in its entirety
and except for obligations of Tenant hereunder intended to survive a termination
of this Lease, with no further obligations of Tenant to Landlord hereunder if an
assignment of this Lease, (b) or with respect to the space therein described as
to a sublet of more than fifty percent (50%) of the Premises, except for
obligations of Tenant hereunder intended to survive a termination of this Lease
with respect to the sublease portion of the Premises recaptured by Landlord and
all obligations of Tenant with respect to the balance of the Premises not
recaptured by Landlord as of the date stated in Tenant's notice, provided,
however, in the event Tenant notifies Landlord within five (5) business days of
receipt of Landlord's Recapture Notice of Tenant's withdrawal of its request to
sublease or assign the Premises ("Withdrawal Notice"), Landlord's Recapture
Notice shall be of no further force and effect, Tenant shall not have the right
to so sublease or assign the requested interest in the Premises and this Lease
shall remain in full force and effect. Tenant's notice shall state the name and
address of the proposed subtenant or assignee, contain a true and complete copy
of the proposed sublease or assignment and sufficient information to permit
Landlord to determine the financial responsibility and character of the proposed
subtenant or assignee shall be delivered to Landlord with said notice. If
Tenant's notice covers all of the space hereby demised, and if Landlord gives
its recapture notice with respect thereto, the Term of this Lease shall expire
on the date stated in Tenant's notice as fully and completely as if that date
had been herein definitely fixed for the expiration of the Term. If, however,
this Lease is terminated pursuant to

                                       21
<Page>

the foregoing with respect to less than the entire Premises, Base Rent and
Tenant's Proportionate Share as defined herein shall be adjusted on the basis of
the number of rentable square feet retained by Tenant, and this Lease as so
amended shall continue thereafter in full force and effect; provided that Tenant
shall pay all costs in connection with the physical subdivision of any portion
of the Premises.

     13.05. LANDLORD'S CONSENT. If Landlord, upon receiving Tenants notice with
respect to any such space, does not have a right to terminate this Lease or a
portion of this Lease or does not exercise its right to terminate as aforesaid,
Landlord will, provided Tenant is not in material default hereunder, not
unreasonably or unduly withhold its consent to Tenants assignment of this Lease
or subletting the space covered by its notice. Landlord shall not be deemed to
have unreasonably withheld its consent to a sublease of part or all of the
Premises or an assignment of this Lease if its consent is withheld because: (a)
Tenant is then in material default hereunder; (b) any notice of termination of
this Lease or termination of Tenants possession was given under Article 17; (c)
the portion of the Premises which Tenant proposes to sublease, including the
means of ingress thereto and egress therefrom and the proposed use thereof, or
the remaining portion of the Premises, or both, will violate any city, state or
federal law, ordinance or regulation, including, without limitation, any
applicable building code or zoning ordinances; (d) the proposed use of the
Premises by the subtenant or assignee does not conform with theme permitted by
Article 5; (e) in the reasonable judgment of Landlord, the proposed subtenant
(in any instance where such subtenant is subleasing 50% or more of the Premises)
or assignee is of a character or is engaged in a business which would be
deleterious to the reputation of the Building, or such subtenant or assignee's
creditworthiness is not equal to or greater than Tenant's; (f) the proposed
subtenant or assignee is a government or a government agency; (g) any other
lease in the Building restricts rental of space in the Building to the proposed
subtenant or assignee; or (h) the proposed subtenant or assignee is an occupant
of the Building; provided, however, that the foregoing are merely examples of
reasons for which Landlord may withhold its consent and shall not be deemed
exclusive of any permitted reasons for reasonably withholding consent, whether
similar to or dissimilar from the foregoing examples.

     13.06. PROFITS. If Tenant, having first obtained Landlord's consent to any
sublease or assignment, or if Tenant or a trustee in bankruptcy for Tenant
pursuant to the Bankruptcy Code, assigns this Lease or sublets the Premises, or
any part thereof, at a rental or for other consideration in excess of the Rent
or pro rata portion thereof due and payable by Tenant under this Lease and
expenses and costs incurred by Tenant in connection with such subletting or
assignment, including without limitation, legal fees and broker fees, then
Tenant shall pay to Landlord as additional rent fifty percent (50%) of any such
excess rent or other monetary consideration within ten (10) days of each receipt
by Tenant of such payments.

     13.07. ASSIGNEE TO ASSUME OBLIGATIONS. If Tenant assigns this Lease as
permitted herein, the assignee shall expressly assume all of the obligations of
Tenant hereunder in a written instrument satisfactory to Landlord and furnished
to Landlord prior to the effective date of the assignment. If Tenant subleases
the Premises as permitted herein, Tenant shall obtain and furnish to Landlord,
prior to the effective date of such sublease and in form satisfactory to
Landlord, the written agreement of such subtenant to the effect that the
subtenant, at Landlord's option and written request, will, at Landlord's
election, attorn to Landlord in the event this Lease terminates before the
expiration of the sublease.

                                       22
<Page>

     13.08. CHANGE OF CONTROL. Notwithstanding anything to the contrary in this
Article, if Tenant is a corporation (other than a corporation the stock of which
is publicly traded) the term "Change of Control" shall mean any change in the
ownership of the shares of stock which constitute control of Tenant other than
by reason of gift or death. The term "control" as used herein means the power,
directly or indirectly, to director cause the direction of the management or
policies of Tenant. If Tenant is a partnership, whether general or limited, the
term "Change of Control" shall mean any change in the ownership of the
partnership interests which constitute control of Tenant other than by reason of
gift or death. If Tenant is a limited liability company, the term "Change of
Control" shall mean any change in more than fifty percent (50%) of the equity
ownership of the limited liability company or mole than fifty percent (50%) of
the voting power of the member(s) or manager(s) of the limited liability
company.

                                   ARTICLE 14

                  WAIVER OF CERTAIN CLAIMS; INDEMNITY BY TENANT

     14.01. WAIVER OF CERTAIN CLAIMS. To the extent not prohibited expressly by
law, Tenant releases Landlord and its agents and employees, from and waives all
claims for damages to person or property sustained by Tenant or by any occupant
of the Premises, the Building or the Development, or by any other person,
resulting directly or indirectly from fire or other casualty, cause or any
existing or future condition, defect, matter or thing in or about the Premises,
the Building or the Development or any part of it, or from any equipment or
appurtenance therein, or from any accident in or about the Building or the
Development, or from any act or neglect of any tenant or other occupant of the
Building or the Development or any part thereof or of any other person,
including Landlord and its agents. This Section shall apply especially, but not
exclusively, to damage caused by water, snow, frost, steam, excessive heat or
cold, sewerage, gas, odors or noise, or the bursting or leaking of pipes or
plumbing fixtures, broken glass, sprinkling, or air conditioning devices or
equipment, or flooding of basements, and shall apply without distinction as to
the person whose act or neglect was responsible for the damage and whether the
damage was due to any of the acts specifically enumerated above, or from any
other thing or circumstance, whether of a like nature or of a wholly different
nature.

     14.02. DAMAGE CAUSED BY TENANT'S NEGLECT. If any damage to the Premises,
the Development or the Building or any equipment or appurtenance therein,
whether belonging to Landlord or to other tenants or occupants of the Building
or the Development, results from any act or neglect of Tenant, its employees,
agents, contractors, licensees or invitees, Tenant shall be liable therefor and
Landlord, at its option, may repair such damage and Tenant, upon demand by
Landlord, shall reimburse Landlord for all costs of such repairs and damages.

     14.03. TENANT RESPONSIBLE FOR PERSONAL PROPERTY. All personal property
belonging to Tenant or any occupant of the Premises that is in the Building, the
Development or the Premises shall be there at the risk of Tenant or other person
only and Landlord shall not be liable for damage thereto or theft or
misappropriation thereof.

     14.04. INDEMNIFICATION. To the extent not prohibited expressly by law,
Tenant agrees to hold Landlord and its agents and employees, harmless and to
indemnify each of them against

                                       23
<Page>

claims and liabilities, including reasonable attorneys' fees, for injuries to
all persons and damage to or theft, misappropriation or loss of property
occurring in or about the Premises and the Development arising from Tenant's
occupancy of the Premises or the conduct of its business or from any activity,
work or thing done, permitted or suffered by Tenant in or about the Premises or
the Development or from any breach or default on the part of Tenant in the
performance of any covenant or agreement on the part of Tenant to be performed
pursuant to the terms of this Lease or due to any other act or omission of
Tenant, its agents, contractors, invitees, licensees or employees. To the extent
not prohibited expressly by law, Landlord agrees to hold Tenant and its agents
and employees harmless from any negligence or willful misconduct of Landlord or
from any breach or default on the part of Landlord in performance of any
covenant or agreement on the part of Landlord to be performed by Landlord
pursuant to the terms of the Lease.

     14.05. LANDLORD'S INDEMNITY. Landlord agrees to hold harmless and indemnify
Tenant from all claims arising out of Landlord's negligence or willful
misconduct.

                                   ARTICLE 15

                        DAMAGE OR DESTRUCTION BY CASUALTY

     15.01. DAMAGE OR DESTRUCTION BY CASUALTY. If the Premises, the Building or
the Common Areas are damaged by fire or other casualty and if such damage does
not render all or a substantial portion of the Premises or the Building
untenantable, then Landlord shall proceed to repair and restore the Building and
the base building portion of the Premises with reasonable promptness, subject to
reasonable delays for insurance adjustments and delays caused by matters beyond
Landlord's reasonable control and Tenant shall restore the Tenant Improvements
and any alterations to the Premises made by Tenant. If any such damage renders
all or a substantial portion of the Premises or the Building untenantable or the
Common Areas unusable, Landlord, with reasonable promptness after the occurrence
of such damage, shall estimate the length of time that will be required to
substantially complete the repair and restoration of such damage to the Building
and the base building portion of the Premises and shall advise Tenant by notice
of such estimate. If it is estimated that the amount of time required to
substantially complete such repair and restoration will exceed two hundred
seventy (270) days from the date such damage occurred, then either Landlord or
Tenant (but as to Tenant, only if all or a substantial portion of the Premises
are rendered untenantable) shall have the right to terminate this Lease as of
the date of such damage upon giving notice to the other at any time within
twenty (20) days after Landlord gives Tenant the notice containing said estimate
(it being understood that, if it elects to do so, Landlord may also give such
notice of termination together with the notice containing said estimate). Unless
this Lease is so terminated, Landlord shall proceed with reasonable promptness
to repair and restore the Building and the base building portion of the Premises
subject to reasonable delays for insurance adjustments and delays caused by
matters beyond Landlord's reasonable control, and also subject to zoning laws
and building codes then in effect. Landlord shall have no liability to Tenant,
and Tenant shall not be entitled to terminate this Lease, except as hereinafter
provided, if such repairs and restoration in fact are not completed within the
time period estimated by Landlord or within two hundred seventy (270) days. If
the Building and the base building portion of the Premises are not repaired or
restored within eighteen (18) months after the date of such fire or other
casualty, then either party may terminate

                                       24
<Page>

this Lease, effective as of the date of such fire or other casualty, by written
notice given to the other party not later than thirty (30) days after the
expiration of said eighteen (18) month period, but prior to substantial
completion of repair or restoration. Notwithstanding anything to the contrary
set forth herein, (a) Landlord shall have no duty pursuant to this Section to
repair or restore any portion of the alterations, additions or improvements
owned by Tenant and which are not affixed to the Premises or to expend for any
repair or restoration amounts in excess of insurance proceeds paid to Landlord
and available for repair or restoration; (b) Tenant shall not have the right to
terminate this Lease pursuant to this Section if the damage or destruction was
caused by the act or neglect of Tenant, its agents or employees; and (c) if any
such damage rendering all or a substantial portion of the Premises or the
Building untenantable shall occur during the last two (2) years of the Term,
Landlord shall have the option to terminate this Lease by giving written notice
to Tenant within sixty (60) days after the date such damage occurred, and if
such option is so exercised, this Lease shall terminate as of the date of such
notice.

     15.02. ABATEMENT OF RENT. In the event any fire or casualty damage not
caused by the act or neglect of Tenant, its agents or employees, renders the
Premises substantially untenantable and if this Lease is not terminated pursuant
to Section 15.01 by reason of such damage, then Rent shall abate during the
period beginning with the date of such damage and ending with the date Landlord
tenders the Premises to Tenant as being ready for occupancy. If any undamaged
portion of the Premises can reasonably be occupied for the conduct of Tenant's
business, such abatement shall be in an amount bearing the same ratio to the
total amount of Rent for such period as the portion of the Premises not ready
for occupancy from time to time bears to the entire Premises. In the event of
termination of this Lease pursuant to Section 15.01, Rent shall be apportioned
on a per diem basis and shall be paid to the date of the fire or casualty.

                                   ARTICLE 16

                                 EMINENT DOMAIN

     If the entire Building, the Common Areas or a substantial part thereof, or
any part thereof which includes all or a substantial part of the Premises, shall
be taken or condemned by any competent authority for any public or quasi-public
use or purpose, the Term of this Lease shall end upon and not before the earlier
of the date when the possession of the part so taken shall be required for such
use or purpose or the effective date of the taking, and without apportionment of
the award to or for the benefit of Tenant. If any condemnation proceeding shall
be instituted in which it is sought to take or damage any part of the Building,
the Common Areas or the Land, the taking of which would prevent the economical
operation of the Building, the Common Areas or the Development, or if the grade
of any street or alley adjacent to the Building, the Common Areas or Parcel One
is changed by any competent authority, and such taking, damage or change of
grade makes it necessary or desirable to remodel the Building or the Common Area
to conform to the taking, damage or changed grade, Landlord shall have the right
to terminate this Lease upon written notice given to Tenant not less than ninety
(90) days prior to the date of termination designated in said notice. In either
of these events, Rent at the then current rate shall be apportioned as of the
date of the termination. No money or other consideration shall be payable by
Landlord to Tenant for the right of termination, and Tenant shall have no right
to share in the condemnation award, whether for a total or partial taking, for
loss of Tenant's

                                       25
<Page>

leasehold or improvements or other loss or expenses or to share in any judgment
for damages caused by the change of grade. If any condemnation proceeding shall
be instituted in which less then all or a substantial part of the Premises is
sought to be taken, but the portion to be taken would result in an inability of
Tenant to conduct normal business operations from the Premises, Tenant shall
have the right to terminate this Lease upon written notice given to Landlord not
less than ninety (90) days prior to the date of termination designated in said
notice.

                                   ARTICLE 17

                                     DEFAULT

     17.01. EVENTS OF DEFAULT. The occurrence of any one or more of the
following matters constitutes a Default by Tenant under this Lease:

          (a) Failure by Tenant to pay any Rent within five (5) days after the
due date;

          (b) Failure by Tenant to pay, within five (5) days after notice of
failure to pay on the due date from Landlord to Tenant, any other moneys

          (c) Failure by Tenant to observe or perform any of the covenants with
respect to assignment and subletting set forth in Article 13;

          (d) Failure by Tenant to comply with Tenant's warranties,
representations or covenants set forth in Article 26;

          (e) Failure by Tenant to cure, promptly after receipt of notice from
Landlord, any hazardous condition which Tenant has created in violation of law
or of this Lease;

          (f) Failure by Tenant to observe or perform any other covenant,
agreement, condition or provision of this Lease, if such failure continues for
thirty (30) days after notice thereof from Landlord to Tenant;

          (g) The levy upon, under writ of execution or the attachment by legal
process of, the leasehold interest of Tenant, or the filing or creation of a
lien (other than such lien in connection with Tenant's bank or lease financings
relating only to Tenant's movable equipment) with respect to such leasehold
interest, which lien shall not be released or discharged within ten (10) days
from the date of such filing;

          (h) Tenant vacates or abandons the Premises or fails to take
possession of the Premises when available for Tenant's commencement of
construction of its Tenant improvements, whether or not Tenant thereafter
continues to pay Rent due under this Lease;

          (i) Tenant becomes insolvent or bankrupt or admits in writing its
inability to pay its debts as they mature, or makes an assignment for the
benefit of creditors, or applies for or consents to the appointment of a trustee
or receiver for Tenant or for the major part of its property;

                                       26
<Page>

          (j) A trustee or receiver is appointed for Tenant or for the major
part of its property and is not discharged within sixty (60) days after such
appointment; or

          (k) Any bankruptcy, reorganization, arrangement, insolvency or
liquidation proceeding, or other proceeding for relief under any bankruptcy law,
or similar law for the relief of debtors, is instituted (i) by Tenant or (ii)
against Tenant and is allowed against it or is consented to by it or is not
dismissed within sixty (60) days after such institution.

     17.02. RIGHTS AND REMEDIES OF LANDLORD. If a Default occurs, Landlord
shall have the rights and remedies hereinafter set forth, which shall be
distinct, separate and cumulative and shall not operate to exclude or deprive
Landlord of any other right or remedy allowed it by law:

          (a) Landlord may terminate this Lease by giving to Tenant notice of
Landlord's election to do so, in which event the Term of this Lease shall end,
and all right, title and interest of Tenant hereunder shall expire, on the date
stated in such notice;

          (b) Landlord may terminate the right of Tenant to possession of the
Premises without terminating this Lease by giving notice to Tenant that Tenants
right to possession shall end on the date stated in such notice, whereupon the
right of Tenant to possession of the Premises or any part thereof shall cease on
the date stated in such notice; and

          (c) Landlord may enforce the provisions of this Lease and may enforce
and protect the rights of Landlord hereunder by a suit or suits in equity or at
law for the specific performance of any covenant or agreement contained herein,
or for the enforcement of any other appropriate legal or equitable remedy,
including recovery of all moneys due or to become due from Tenant under any of
the provisions of this Lease.

     17.03. RIGHT TO RE-ENTER. If Landlord exercises either of the remedies
provided in Sections 17.02(a) or (b), Tenant shall surrender possession and
vacate the Premises and immediately deliver possession thereof to Landlord, and
Landlord may re-enter and take complete and peaceful possession of the Premises,
with or without process of law, full and complete license to do so being hereby
granted to Landlord, and Landlord may remove all occupants and property
therefrom, using such force as may be necessary, without being deemed guilty in
any manner of trespass, eviction or forcible entry and detainer and without
relinquishing Landlord's right to Rent or any other right given to Landlord
hereunder or by operation of law.

     17.04. CURRENT DAMAGES. If Landlord terminates the right of Tenant to
possession of the Premises without terminating this Lease, Landlord shall have
the right to immediate recovery of all amounts then due hereunder. Such
termination of possession shall not release Tenant, in whole or in part, from
Tenant's obligation to pay Rent hereunder for the full Term, and Landlord shall
have the right, from time to time, to recover from Tenant, and Tenant shall
remain liable for, all Base Rent, Rent Adjustments and any other sums accruing
as they become due under this Lease during the period from the date of such
notice of termination of possession to the stated end of the Term, provided
further Landlord may accelerate amounts due hereunder for a period of up to one
year at a time. In any such case, Landlord may relet the Premises or any part
thereof for the account of Tenant for such rent, for such time (which may be for
a term extending beyond the Term of this Lease) and upon such terms as Landlord
shall determine and may collect the

                                       27
<Page>

rents from such reletting. Landlord shall not be required to accept any tenant
offered by Tenant or to observe any instructions given by Tenant relative to
such reletting. Also, in any such case, Landlord may make repairs, alterations
and additions in or to the Premises and redecorate or reconstruct the same to
the extent deemed by Landlord necessary or desirable and in connection therewith
change the locks to the Premises, and Tenant upon demand shall pay the cost of
all of the foregoing together with Landlord's expenses of reletting. The rents
from any such reletting shall be applied first to the payment of the expenses of
reentry, redecoration, reconstruction, repair and alterations and the expenses
of reletting and second to the payment of Rent herein provided to be paid by
Tenant. Any excess or residue shall operate only as an offsetting credit against
the amount of Rent due and owing as the same thereafter becomes due and payable
hereunder, and the use of such offsetting credit to reduce the amount of Rent
due Landlord, if any, shall not be deemed to give Tenant any right, title or
interest in or to such excess or residue and any such excess or residue shall
belong to Landlord solely, and in no event shall Tenant be entitled to a credit
on its indebtedness to Landlord in excess of the aggregate sum (including Base
Rent and Rent Adjustments) which would have been paid by Tenant for the period
for which the credit to Tenant is being determined, had no Default occurred. No
such reentry or repossession, repairs, alterations and additions, or reletting
shall be construed as an eviction or ouster of Tenant or as an election on
Landlord's part to terminate this Lease, unless a written notice of such
intention is given to Tenant, or shall operate to release Tenant in whole or in
part from any of Tenant's obligations hereunder, and Landlord, at any time and
from time to time, may sue and recover judgment for any deficiencies remaining
after the application of the proceeds of any such reletting.

     17.05. FINAL DAMAGES. If this Lease is terminated by Landlord pursuant to
Section 17.02(a), Landlord shall be entitled to recover from Tenant all Rent
accrued and unpaid for the period up to and including such termination date, as
well as all other additional sums payable by Tenant, or for which Tenant is
liable or for which Tenant has agreed to indemnify Landlord under any of the
provisions of this Lease, which may be then owing and unpaid, and all costs and
expenses, including court costs and attorneys' fees incurred by Landlord in the
enforcement of its rights and remedies hereunder, and, in addition, Landlord
shall be entitled to recover as damages for loss of the bargain and not as a
penalty (a) the unamortized portion of any concessions offered by Landlord to
Tenant in connection with this Lease, including without limitation Landlord's
contribution to the cost of tenant improvements and alterations, if any,
installed by either Landlord or Tenant pursuant to this Lease or the Work Letter
or brokerage commission paid by Landlord on account of this Lease, (b) the
aggregate sum which at the time of such termination represents the excess, if
any, of the present value of the aggregate rents which would have been payable
after the termination date had this Lease not been terminated, including,
without limitation, Base Rent at the annual rate or respective annual rates for
the remainder of the Term provided for in Article 3 of this Lease or elsewhere
herein and the amount projected by Landlord to represent Rent Adjustments for
the remainder of the Term pursuant to Article 4 of this Lease, over the then
present value of the then aggregate fair rental value of the Premises for the
balance of the Term, such present worth to be computed in each case on the basis
of a five percent (5%) per annum discount from the respective dates upon which
such rentals would have been payable hereunder had this Lease not been
terminated, and (c) any damages in addition thereto, including reasonable
attorneys' fees and court costs, which Landlord sustains as a result of the
breach of any of the covenants of this Lease other than for the payment of Rent.

                                       28
<Page>

     17.06. REMOVAL OF PERSONAL PROPERTY. All property of Tenant removed from
the Premises by Landlord pursuant to any provision of this Lease or applicable
law may be handled, removed or stored by Landlord at the cost and expense of
Tenant, and Landlord shall not be responsible in any event for the value,
preservation or safekeeping thereof. Tenant shall pay Landlord for all expenses
incurred by Landlord with respect to such removal and storage so long as the
same is in Landlord's possession or under Landlord's control. All such property
not removed from the Premises or retaken from storage by Tenant within thirty
(30) days after the end of the Term, however terminated, at Landlord's option,
shall be conclusively deemed to have been conveyed by Tenant to Landlord as by
bill of sale without further payment or credit by Landlord to Tenant.

     17.07. ATTORNEYS' FEES. Tenant shall pay all of Landlord's costs, charges
and expenses, including court costs and attorneys' fees, incurred in enforcing
Tenant's obligations under this Lease, incurred by Landlord in any action
brought by Tenant in which Landlord is the prevailing party, or incurred by
Landlord in any litigation, negotiation or transaction in which Tenant causes
Landlord, without Landlord's fault, to become involved or concerned.

     17.08. ASSUMPTION OR REJECTION IN BANKRUPTCY. If Tenant is adjudged
bankrupt, or a trustee in bankruptcy is appointed for Tenant, Landlord and
Tenant, to the extent permitted by law, agree to request that the trustee in
bankruptcy determine within sixty (60) days thereafter whether to assume or to
reject this Lease.

     17.09. DEFAULT UNDER OTHER LEASES. If the term of any lease, other than
this Lease, for any space in the Building under which Tenant is now or hereafter
the tenant, shall be terminated or terminable after the making of this Lease
because of any default by Tenant under such other lease, such fact shall empower
Landlord, at Landlord's sole option, to terminate this Lease by notice to Tenant
or to exercise any of the rights or remedies set forth in Section 17.02.

     17.10. RIGHT TO PERFORM. If Tenant shall fail to make any payment or
perform any other act on its part to be performed hereunder, and such failure is
not cured within any applicable grace or cure period, Landlord may, but shall
not be obligated to, perform any such obligation of Tenant, and to recover from
Tenant, as additional rent hereunder, the actual costs incurred by Landlord in
performing such obligation, which costs shall be payable within thirty (30) days
after Landlord's written demand thereof accompanied by reasonable substantiation
thereof. Landlord shall have (in addition to any other right or remedy of
Landlord) the same rights and remedies in the event of the nonpayment of sums
due under this Section as in the case of default by Tenant in the payment of
Rent. All sums paid by Landlord and all penalties, interest and costs in
connection therewith, shall be due and payable by Tenant together with interest
thereon at the Default Rate, which shall be calculated from the date incurred by
Landlord until the date of payment.

                                   ARTICLE 18

                                  SUBORDINATION

     18.01. SUBORDINATION. Landlord from time to time may execute and deliver a
first mortgage or first trust deed in the nature of a mortgage (both hereinafter
referred to as a "First Mortgage"), against the Land and Building or any
interest therein or in the Development. If requested by the mortgagee or trustee
under any First Mortgage, Tenant will either (a) subordinate its interest in
this Lease to said First Mortgage, and to any and all advances made thereunder
and to the interest thereon, and to all renewals, replacements, supplements,
amendments, modifications and extensions thereof, or (b) make certain of
Tenant's rights and interests in this Lease superior thereto; and Tenant will
promptly execute and deliver such agreement or agreements as may be reasonably
required by such mortgagee or trustee under any First Mortgage. Tenant covenants
that it will not subordinate this Lease to any mortgage or trust deed other than
a First Mortgage without the prior written consent of the holder of the First
Mortgage.

     18.02. LIABILITY OF HOLDER OF FIRST MORTGAGE; ATTORNMENT. It is further
agreed that (a) if any First Mortgage is foreclosed, (i) the holder of the First
Mortgage, ground lessor, or their respective grantees, or purchaser at any
foreclosure sale (or grantee in a deed in lieu of foreclosure), as the case may
be, shall not be (x) liable for any act or omission of any prior landlord
(including Landlord), (y) subject to any offsets or counterclaims which Tenant
may have against a prior landlord (including Landlord), or (z) bound by any
prepayment of Base Rent or Rent Adjustments which Tenant may have made in excess
of the amounts then due for the next succeeding month, (ii) the liability of the
mortgagee or trustee hereunder or purchaser at such foreclosure sale or the
liability of a subsequent owner designated as Landlord under this Lease shall
exist only so long as such trustee, mortgagee, purchaser or owner is the owner
of the Building or Land and such liability shall not continue or survive after
further transfer of ownership; and (iii) upon request of the mortgagee or
trustee, if the First Mortgage is foreclosed, Tenant will attorn, as Tenant
under this Lease, to the purchaser at any foreclosure sale under any First
Mortgage, and Tenant will execute such instruments as may be necessary or
appropriate to evidence such attornment; and (b) this Lease may not be modified
or amended so as to reduce the rent or shorten the term provided hereunder, or
so as to affect adversely in any other respect to any material extent the rights
of Landlord, nor shall this Lease be canceled or surrendered, without the prior
written consent, in each instance, of the mortgagee or trustee under any First
Mortgage.

     18.03. CONTINUED RIGHT OF QUIET ENJOYMENT. Notwithstanding anything to the
contrary in this Article 18, all of Tenant's obligations with respect to
subordination and attornment is subject to such mortgagee or trustee, holder of
the First Mortgage, ground lessor, or their respective grantees, or purchaser at
any foreclosure sale (or grantee in a deed in lieu of foreclosure), as the case
may be, agreeing in writing that provided Tenant is not in default hereunder
beyond applicable cure periods neither Tenant's right to quiet enjoyment under
this Lease nor Tenant's right to continue to occupy the Premises and conduct its
businesses thereon under this Lease shall be interfered with.

                                       30

     18.04. SHORT FORM LEASE. Should any prospective mortgagee require execution
of a short form of lease for recording (containing the names of the parties, a
description of the Premises, and the term of this Lease) or a certification from
Tenant concerning this Lease in such form as may be required by a prospective
mortgagee, Tenant agrees to execute promptly such short form of lease or
certificate and deliver the same to Landlord within ten (10) days following the
request therefor.

                                   ARTICLE 19

                              MORTGAGEE PROTECTION

     Tenant agrees to give any holder of any First Mortgage, as defined in
Section 18.01, against the Land or Building, or any interest therein, by
registered or certified mail, a copy of any notice or claim of default served
upon Landlord by Tenant, provided that prior to such notice Tenant has been
notified in writing (by way of service on Tenant of a copy of an assignment of
Landlord's interests in leases, or otherwise) of the address of such First
Mortgage holder. Tenant further agrees that if Landlord has failed to cure such
default within thirty (30) days after such notice to Landlord (or if such
default cannot be cured or corrected within that time, then such additional time
as may be necessary if Landlord has commenced cure or correction within such
thirty (30) days and is pursuing diligently the remedies or steps necessary to
cure or correct such default), then the holder of the First Mortgage shall have
an additional thirty (30) days within which to cure or correct such default.

                                   ARTICLE 20

                              ESTOPPEL CERTIFICATE

     Tenant agrees that from time to time within ten (10) days of written
request received from Landlord, or the holder of any First Mortgage or any
ground lessor, Tenant (or any permitted assignee, subtenant, licensee,
concessionaire or other occupant of the Premises claiming by, through or under
Tenant) will deliver to Landlord or to the holder of any First Mortgage or
ground lessor, a statement in writing signed by Tenant (and/or such other party)
certifying (a) that this Lease is unmodified and in full force and effect (or if
there have been modifications, that this Lease as modified is in full force and
effect and identifying the modifications); (b) the date upon which Tenant began
paying Rent and the dates to which Rent and other charges have been paid; (c)
that Landlord is not in default under any provision of this Lease, or, if in
default, the nature thereof in detail; (d) that the Premises have been completed
in accordance with the terms hereof and Tenant is in occupancy and paying Rent
on a current basis with no rental offsets or claims; (e) that there has been no
prepayment of Rent other than that provided for in this Lease; (f) that there
are no actions, whether voluntary or involuntary, pending against Tenant under
the bankruptcy laws of the United States or any State thereof; and (g) such
other matters as may be required by Landlord, the holder of the First Mortgage
or ground lessor.

                                   ARTICLE 21

                            SUBROGATION AND INSURANCE

     21.01. WAIVER OF SUBROGATION. Landlord and Tenant agree to have all fire
and extended coverage and other property damage insurance which may be carried
by either of them endorsed with a clause providing that any release from
liability of or waiver of claim for recovery from the other party entered into
in writing by the insured thereunder prior to any loss or damage shall not
affect the validity of such policy or the right of the insured to recover
thereunder, and providing further that the insurer waives all rights of
subrogation which such insurer might have against the other party. Without
limiting any release or waiver of liability or recovery set forth elsewhere in
this Lease, and notwithstanding anything in this Lease which may appear to be to
the contrary, each of the parties hereto waives all claims for recovery from the
other party for any loss or damage to any of its property insured under valid
and collectible insurance policies to the extent of any recovery collectible
under such insurance policies. Notwithstanding the foregoing or anything
contained in this Lease to the contrary, any release or any waiver of claims
shall not be operative, nor shall the foregoing endorsements be required, in any
case where the effect of such release or waiver is to invalidate insurance
coverage or to invalidate the right of the insured to recover thereunder or to
increase the cost thereof (provided that in the case of increased cost, the
other party shall have the right, within ten (10) days following written notice
thereof, to pay such increased cost and thereby keep such release or waiver in
full force and effect).

     21.02. TENANT'S INSURANCE. Tenant shall carry insurance during the entire
Term hereof with terms, coverages and companies satisfactory to Landlord and
with such increases in limits as Landlord may request from time to time, but
initially Tenant shall maintain the following coverages in the following
amounts:

          (a) Commercial general liability insurance, including contractual
liability, on an occurrence basis, in an amount not less than Three Million
Dollars ($3,000,000.00) per occurrence, covering Tenant as a named insured and
Landlord and the managing agent for the Building and the respective officers,

assertion of liability and continue such defense at all times thereafter

                                   ARTICLE 27

                                SECURITY DEPOSIT

     27.01. SECURITY DEPOSIT. Tenant shall deposit with Landlord simultaneous
hereto the amount of Five Hundred Seventeen Thousand Six Hundred Eighty-Six
Dollars ($517,686) as security for the full and faithful performance of every
provision of this Lease to be performed by Tenant; provided that the Security
Deposit shall, provided Tenant is not in default at the time of the proposed
reduction or has not been in monetary default within the immediately prior
twelve (12) month period, be reduced (a) on August 1, 2008 to $388,265; (b) on
August 1, 2010 to $258,843 and (b) on August 1, 2011 to $129,422 and any such
excess deposit amount as of such dates shall be promptly returned to Tenant. If
Tenant is in Default with respect to any provision of this Lease, including, but
not limited to, the provisions relating to the payment of Rent, Landlord may
use, apply or retain all or any part of the security deposit for the payment of
any Rent and any other sum with respect to which Tenant is in Default, or for
the payment of any other amount which Landlord may spend or become obligated to
spend by reason of Tenant's Default or to compensate Landlord for any other loss
or damage which Landlord may suffer by reason of Tenant's Default. If any
portion of the security deposit is to be used or applied, Tenant, within fifteen
(15) days after written demand therefor, shall deposit cash with Landlord in an
amount sufficient to restore the security deposit to its then current required
amount and Tenant's failure to do so shall be a material breach of this Lease.
Landlord shall not be required to keep the security deposit separate from its
general funds and Tenant shall not be entitled to interest on any security
deposit. If Tenant fully and faithfully performs every provision of this Lease
to be performed by it, the security deposit or any balance thereof shall be
returned to Tenant (or at Landlord's option to the last assignee of Tenant's
interest hereunder) within thirty (30) days after the expiration of the Term and
Tenants vacation of the Premises.

     27.02. TRANSFER OF SECURITY DEPOSIT. Tenant hereby agrees not to look to
any mortgagee as mortgagee, mortgagee in possession, or successor in title to
the Building for accountability for any security deposit required by Landlord
hereunder, unless said sums have actually been received by said mortgagee as
security for Tenant's performance of this Lease. Landlord may deliver the funds
deposited hereunder by Tenant to the purchaser of Landlord's interest in the
Building, in the event that such interest is sold, and if Landlord has delivered
all or a portion of such security deposit to such successor landlord, thereupon
Landlord shall be discharged from any further liability with respect to such
portion of the security deposit so delivered.

     27.03. LETTER OF CREDIT. Notwithstanding anything in subsection 27.01 above
to the contrary, in lieu of a cash Security Deposit, Tenant may deliver to
Landlord, simultaneous herewith, a clean, irrevocable, non-documentary and
unconditional Letter of Credit issued by and drawn upon Silicon Valley Bank or
any other commercial bank, trust company, national banking association or
savings and loan association having offices for banking purposes in the City of
Chicago and which is a member of the Chicago Clearinghouse association (the
"Issuing Bank") and which is then rated, without regard to qualification of such
rating by symbols such as "+" or

                                       39
<Page>

"-" or numerical notation, "Aa" or better by Moody's Investors Service and "AA"
or better by Standard & Poor's Corporation, and has combined capital, surplus
and undivided profits of net less than $500,000,000.00, which Letter of Credit
shall have a term of not less than one year, be in form and content satisfactory
to Landlord in its sole discretion, be for the account of Landlord, be in the
amount of the Security Deposit then required to be deposited hereunder, be
subject to partial draw by Landlord if Landlord so elects and be fully
transferable by Landlord to successor owners of the Building without the payment
of any fees or charges, it being agreed that if any such fees or charges shall
be so imposed then such fees or charges, shall be paid by Tenant. The Letter of
Credit shall provide that it shall be deemed automatically renewed, without
amendment, for consecutive periods of one year each thereafter during the term
of this Lease, unless the Issuing Bank sends notice (the "Non-Renewal Notice")
to Landlord by certified mail, return receipt requested, not less than thirty
(30) days next preceding the then expiration date of the Letter of Credit that
it elects not to have such Letter of Credit renewed. Additionally, the Letter of
Credit shall provide that Landlord shall have the right, exercisable within
twenty (20) days of its receipt of the Non-Renewal Notice, by sight draft on the
Issuing Bank, to receive the monies represented by the then existing Letter of
Credit and to hold such proceeds pursuant to the terms of this Article 27 as a
cash Security Deposit, securing Tenants obligations hereunder pending the
replacement of such Letter of Credit. If a default shall have occurred and be
continuing with respect to any provision of this Lease, including but not
limited to the provisions relating to the payment of Rent, Landlord may apply or
retain the whole or any part of the cash security so deposited or may notify the
Issuing Bank and thereupon receive all the monies represented by the Letter of
Credit and use, apply, or retain the whole or any part of such proceeds, as
provided in this Article 27. Any portion of the cash proceeds of the Letter of
Credit not so used or applied by Landlord in satisfaction of the obligations of
Tenant as to which such default shall have occurred shall be held by Landlord.
If Landlord applies or retains any part of the cash security or proceeds of the
Letter of Credit, as the case may be, Tenant shall, within five (5) days after
written demand therefor, deposit with Landlord the amount so applied or retained
so that Landlord shall have the full Security Deposit required pursuant to
Article 27 on hand at all times during the Term. If Tenant shall fully and
faithfully comply with all of the terms, provisions, covenants and conditions of
this Lease, the Letter of Credit shall be returned to Tenant after the
Expiration Date and after delivery of possession of the Premises to Landlord. In
the event of a sale of Landlord's interest in the Premises, within thirty (30)
days of notice of such sale, Tenant, at Tenant's sole cost and expense, shall
arrange for the transfer of the Letter of Credit to the new landlord, as
designated by Landlord, or have the Letter of Credit reissued in the name of the
new landlord and Landlord shall thereupon be released by Tenant from all
liability for the return of the Letter of Credit; provided, however, that if the
Letter of Credit is reissued, Landlord shall return the original Letter of
Credit issued to Landlord's name to Tenant.

     Notwithstanding the foregoing, and subject to satisfaction by Tenant of the
condition precedent that Tenant has consistently and timely made all payments of
Rent due and payable under this Lease when due and was not delinquent in any
payment thereof within the prior twelve (12) months, and that no non-monetary
default has occurred, Tenant shall have the right to reduce the amount of the
Letter of Credit in the amounts and at the times set forth as follows:

     Notwithstanding the foregoing, in the event of the occurrence of any
default under the Lease pursuant to which Landlord draws all or any portion of

                        TITLE AND COVENANT AGAINST LIENS

     Landlord's title is paramount and always shall be paramount to the title of
Tenant and nothing contained in this Lease shall empower Tenant to do any act
which can, shall or may encumber the title of Landlord. Tenant covenants and
agrees not to suffer or permit any lien of mechanics or materialmen to be placed
upon or against the Premises, the Building, the Development, the Land or against
Tenants leasehold interest in the Premises and, in case of any such lien
attaching, to pay and remove the same immediately. Tenant has no authority or
power to cause or permit any lien or encumbrance of any kind whatsoever, whether
created by act of Tenant, operation of law or otherwise, to attach to or be
placed upon the Premises, the Building, the Development or the Land, and any and
all liens and encumbrances created by Tenant shall attach only to Tenant's
interest in the Premises. If any such liens so attach and Tenant fails to pay
and remove the same within ten (10) days, Landlord, at its election, may pay and
satisfy the same and in such event the sums so paid by Landlord, with interest
from the date of Landlord's payment thereof at the rate set forth in Section
30.08 for amounts owed to Landlord by Tenant, shall be deemed to be additional
rent due and payable by Tenant at once without notice or demand. Tenant agrees
to indemnify, hold harmless and defend Landlord from any loss, cost, damage or
expense, including attorney's fees, arising out of any lien claim or out of any
other claim relating to work done or materials supplied to the Premises at
Tenant's request or on Tenant's behalf. Tenant shall remove any filed lien
within ten (10) days of the filing of such lien.

Building, or any assignment of this Lease by Landlord, said Landlord making such
sale, conveyance or assignment shall be and hereby is entirely freed and
relieved of all covenants and obligations of Landlord hereunder accruing after
such sale, conveyance or assignment, and Tenant agrees to look solely to such
purchaser, grantee or assignee with respect thereto, provided such purchaser,
grantee or assignee has agreed in writing to assume all Landlord's obligations

written instrument executed by Landlord and Tenant.

     29.11. FORCE MAJEURE. If Landlord fails to perform timely any of the terms,

period of delay resulting from such cause. If Tenant fails to perform any of its
obligations (excluding however any of its monetary obligations hereunder or
Tenant's obligation to vacate the Premises at the expiration or earlier

               (ii) Remove any or all such Wiring and restore the Premises and
          risers to their condition existing prior to the installation of the

               (iii) Require Tenant to perform the Wire Restoration Work at
          Tenant's sole cost and expense.

     29.17. ADDITIONAL RENT. Any sum owed or reimbursable by Tenant to Landlord
under this Lease (excluding monthly Base Rent) shall be considered additional
rent hereunder, and, except for items of additional rent for which demand is
required pursuant to the express terms of this Lease, shall be payable without
demand, set-off or deduction, except as otherwise expressly provided in this
Lease.

     29.18. NO ACCORD OR SATISFACTION. No payment by Tenant or receipt by
Landlord of a lesser amount than the rent and other sums due hereunder shall be
deemed to be other than on account of the earliest rent or other sums due, nor

payment be deemed an accord and satisfaction; and Landlord may accept such check
or payment without prejudice to Landlord's right to recover the balance of such
rent or other sum and to pursue any other remedy provided in this Lease.

     29.19. QUIET POSSESSION. Upon Tenant's paying the Rent reserved hereunder
and observing and performing all of the covenants, conditions and provisions on
Tenant's part to be observed and performed hereunder, Tenant shall have quiet

Tenant's occupancy of the Premises, a one time tap on fee ("Tap Fee"), which
shall be the sole property of Landlord, of Twelve Thousand Five Hundred Dollars
($12,500) per floor or partial floor.

     Except for the Tap Fee, Tenant shall not be obligated to pay Landlord any
fee for Tenant's use of the Building's supplemental cooling riser system, which
system shall be generally available for Tenant's use twenty-four (24) hours a
day, seven (7) days a week. Notwithstanding the foregoing, Landlord shall have
the right, upon forty eight (48) hours notice to Tenant (except in an emergency,
in which event no notice is required) to cease operation of

                                       44

                         AMERICANS WITH DISABILITIES ACT

     The parties acknowledge that the Americans With Disabilities Act of 1990
(421 J.S.C. Sections 12101 et seq.) and regulations and guidelines promulgated
thereunder, as all of the same may be amended and supplemented from time to time
(collectively referred to herein as the "ADA") establish requirements under
Title III of the ADA ("Title III") pertaining to business operations,
accessibility and barrier removal. Tenant's Architect (as defined in the Work
Letter) shall design the Premises to comply with ADA requirements and
Tenant shall throughout the Term be responsible for the Premises' compliance
therewith. Landlord shall, as an Expense, be responsible for the Building's
continuing compliance with ADA, excluding the Premises.

                                   ARTICLE 31

                              RIGHT OF FIRST OFFER

     Subject to any pre-existing rights of Cole Taylor Bank to lease all or any
portion of the Additional Premises (as defined below), and provided Tenant is
not in default under the terms and conditions of the Lease as of the date Tenant
notifies Landlord of its desire to exercise a Right of First Offer (as defined
below), Tenant shall have a right of first offer ("Right of First Offer") to
lease any and all space contiguous to the Premises which becomes available for

                                       45
<Page>

leasing to third parties during the Term ("Additional Premises"), subject to the
terms and conditions hereof. Immediately prior to the date on which Landlord
contemplates submitting a "Proposal" to a third party with respect to the
leasing of any Additional Premises, Landlord shall notify Tenant in writing, as
to the date in the future ("Availability Date") when such Additional Premises
shall be available to Tenant, a general description of such Additional Premises,
and the Prevailing Market Rental Rate (as defined hereafter) ("Landlord's
Notice"). Tenant must notify Landlord, in writing, within fifteen (15) days
immediately following Tenant's receipt of Landlord's Notice, of Tenant's desire
to exercise its Right of First Offer with respect to that portion of the
Additional Premises designated in Landlord's Notice ("Designated Space").
Tenant's Right of First Offer must be exercised as to one hundred percent (100%)
of the Designated Space. If Tenant does not notify Landlord of its election to
exercise its Right of First Offer with respect to the Designated Space within
said fifteen (15) day period, then, in such case, Tenant shall be deemed to have
elected not to exercise its Right of First Offer with respect to the Designated
Space, and shall waive its Right of First Offer with respect to such Designated
Space. If Tenant elects to exercise its Right of First Offer and so notifies
Landlord of same within the aforesaid fifteen (15) day period, then, in such
case, Tenant shall lease the Designated Space as of the Availability Date on the
same terms and conditions contained in the Lease, except (i) Base Rent for the
Designated Space shall be the then Prevailing Market Rental Rate ("First Offer
Base Rent"); (ii) the term "Premises" for all purposes of the Lease shall
include the Designated Space; (iii) the numerator of Tenant's Proportionate
Share shall increased by the amount of the rentable area contained within the
Designated Space; and (iv) the Designated Space shall be delivered to Tenant in
the then as-is condition without any allowance.

     In the event Tenant exercises the Right of First Offer, Landlord and Tenant
shall, within fifteen (15) days of such exercise, mutually execute an amendment
to this Lease ("Expansion Amendment") reflecting the addition of such space to
the Premises pursuant to the terms hereinabove set forth and increasing the
Tenants Proportionate Share of Operating Expenses, the Monthly Base Rent, and
the Annual Base Rent to reflect same.

     "Prevailing Market Rental Rate" shall mean an annual amount per rentable
square foot determined by Landlord for a term equivalent to the period for which
Prevailing Market Rental Rate is being determined beginning with the first (la)
day of the subject period that a creditworthy, non equity tenant leasing
comparable renewal space to Tenant would pay, and a willing, comparable landlord
of an office building comparable to the Building located in the immediate O'Hare
office market ("Market") would accept at arms length, giving appropriate
consideration to annual rental rate per rentable square foot, rental escalations
(including type, base year and stops), length of lease term, size and location
of the premises being leased, allowances, concessions and other generally
applicable terms and conditions prevailing for comparable space in comparable
buildings located in the market.

     Notwithstanding anything herein which may be to the contrary, in the event
Tenant fails to elect to exercise any Right of First Offer, and Landlord desires
to lease such space to a third party within three (3) months of such rejection
at a rate less than ninety percent (90%) of that offered to Tenant, Tenant's
Right of First Offer shall be reinstated.

                                   ARTICLE 32

                                 RENEWAL OPTION

     Upon written notice to Landlord ("Renewal Option Notice") received by
Landlord no less than one (1) year prior to the expiration of the Term, Tenant
shall have the right and option ("Renewal Option") to extend the Term for the
entire Premises for one (1) additional and consecutive five (5) year period
("Renewal Term") on the terms and conditions hereof provided, however, if Tenant
exercises the Renewal Option, Rent for the Premises during the Renewal Term
shall be the Prevailing Market Rental Rate. Failure to give notice as above
provided shall constitute an election by Tenant not to exercise the Renewal
Option and this Lease shall terminate in accordance with its terms. If Tenant so
gives the Renewal Option Notice within said one (1) year period, Landlord shall
provide Tenant with its written determination ("Determination Notice") of the
Prevailing Market Rental Rate within ten (10) business days after Landlord's
receipt of the Renewal Option Notice. If Tenant accepts such determination, or
fails to revoke its Renewal Option Notice in writing within five (5) days after
receipt of the Determination Notice, then Landlord's determination of the
Prevailing Market Rental Rate shall control, and the remainder of this Article
33 shall apply. If Tenant revokes its Renewal Option Notice within said five (5)
day period, the Renewal Option shall be deemed extinguished.

     The Renewal Option provided above is conditioned upon and shall be deemed
validly exercised if, and only if, on the date of exercise of the Renewal
Option, and also on the first date of the Renewal Term, the Tenant is not in
default in its obligations under this Lease (regardless of whether any cure or
grace periods have lapsed); provided, Landlord shall have the right to waive
such condition in its sole discretion. Any attempt by Tenant to exercise its
Renewal Option by any method, or at any time, or in any circumstances except as
specifically set forth above shall, at the sole option and discretion of
Landlord, be null and void and of no force or effect. Within twenty (20) days
after Tenant exercises the Renewal Option as aforesaid for the Renewal Term,
Landlord and Tenant shall execute a document evidencing all of the following:
(i) the exercise by the Tenant of the Renewal Option; (ii) the expiration of the
Term of the Lease, as the case may be, as extended by the exercise of the
Renewal Option; (iii) the rental rate during such Renewal Term; and (iv) such
other facts as may be reasonably requested by the Landlord. The Renewal Option
may be exercised only by, and is personal to, Tenant, and may not be exercised
by or for the benefit of any other party. Notwithstanding anything contained in
this Section to the contrary, any attempt by Tenant to exercise the Renewal
Option by any method, or at any time, or in any circumstance, except as
specifically set forth above, shall, at the sole option and discretion of
Landlord, be null and void and of no force or effect.

     For purposes of this Section, "Prevailing Market Rental Rate" shall mean an
annual amount per rentable square foot determined by Landlord for a term
equivalent to the period for which Prevailing Market Rental Rate is being
determined beginning with the first (1st) day of the subject period that a
creditworthy, non-equity tenant leasing comparable renewal space to Tenant would
pay, and a willing, comparable landlord of an office building comparable to the
Building located in the immediate O'Hare office market ("Market") would accept
at arms length, giving appropriate consideration to annual rental rate per
rentable square foot, rental escalations (including type, base year and stops),
length of lease term, size and location of the premises being leased,
allowances, concessions and other generally applicable terms and conditions
prevailing for comparable space in comparable buildings located in the Market.

                               TERMINATION OPTION

     Provided Tenant is not in default hereunder, Tenant shall have the option
to terminate the Lease at the end of the eighty fourth (84h) calendar month
following the Commencement Date ("Termination Option"), provided Tenant: (i)
furnishes Landlord with not less than one (1) year prior written notice of its
exercise of its right to terminate this Lease pursuant to this Article 34; and
(ii) pays Landlord, concurrently with the giving of such notice, an amount equal
to the unamortized portion (discounted at seven percent (7%) interest per annum)
of the (i) Tenant Improvements Allowance (ii) brokerage commissions relating to
this Lease and (iii) the free rent period applicable to the Term and, in
addition thereto, four (4) months Rent ("Termination Fee"). The Termination
Option may be exercised only by, and is personal to, Tenant, and may not be
exercised by or for the benefit of any other party. Any attempt by Tenant to
exercise its Termination Option by any method, or at any time, or in any
circumstances except as specifically set forth above shall, at the sole option
and discretion of Landlord, be null and void and of no force or effect.

                               ROOF COMMUNICATIONS

     34.01 Tenant and its permitted assignees or subtenants shall have the
right, without charge, from time to time to locate communications equipment
approved by Landlord on the roof of the Building in a location approved by
Landlord ("Tenant Roof Communications Facilities").

     34.02 Tenant's right to install the Tenant Roof Communications Facilities
are subject to Landlord's prior review and approval of plans and specifications
and location applicable to the Tenant Roof Communications Facilities, Tenant
obtaining all applicable governmental approvals with respect thereto and
Landlord's approval of the installation contractor and such contractor complying
with all of Landlord's requirements in conjunction with such installation.

     34.03 Tenant's operation of the Tenant Roof Communications Facilities shall
be performed in such a manner as to not unreasonably interfere with
telecommunication activities of other tenants in the Development.

     34.04 Tenant agrees to hold Landlord harmless and to indemnify Landlord
against any loss, cost or damage to the roof of the Building caused by
installation, operation or removal of the Tenant Roof Communications Facilities.

     34.05 Tenant shall insure the Tenant Roof Communications Facilities in form
and substance reasonably acceptable to Landlord.

     34.06 Tenant shall, at its sole cost and expense, maintain the Tenant Roof
Communications Facilities throughout the Term.

     34.07 Tenant shall, on or prior to the end of the Term, remove the Tenant
Roof Communications Facilities and repair any damage to the roof occasioned by
such removal.

     34.08 Tenant acknowledges the Federal Aviation Administration restricts the
maximum height of facilities above the roof of the Building. In addition, Tenant
agrees, to the extent any of its telecommunications equipment to be located on
the roof of the Building extends beyond the height of the parapet wall
surrounding the roof, Tenant shall provide screening of such telecommunications
equipment in form and substance reasonably acceptable to Landlord.

                                   WORK LETTER

     ORIX O'HARE II, INC., an Illinois corporation (the "Landlord"), and PICIS,
INC., a Delaware corporation (the "Tenant") are executing simultaneously
herewith a lease (the "Lease") leasing certain office space (the "Premises")
more particularly described in the Lease. In connection with the execution of
that Lease, the parties have further agreed as follows:

     1. BASE BUILDING. Landlord, at its sole cost and expense, has completed the
Building Shell and Core substantially in accordance with the Outline Building
Plans.

     2. PRELIMINARY PLANS AND SCOPE DRAWINGS. Tenant, at Landlord's cost
not to exceed $2,221.83, has caused to be prepared and delivered to Landlord
preliminary plans of the Premises (the "Preliminary Plan"), preliminarily
depicting the construction work required by Tenant to improve the Shell and Core
of the Premises for Tenant's use and occupancy. The Preliminary Plan shall be
subject to Landlord's approval, not to be unreasonably withheld or delayed.

     3. TENANT IMPROVEMENT WORK. Tenant shall cause to be performed the tenant
improvement work ("Tenant Improvements") provided for in the Approved Working
Drawings (as hereinafter defined).

     4. WORKING DRAWINGS. Tenant has prepared and submitted to Landlord, for
Landlord's approval, final architectural, mechanical (including heating,
ventilating and air-conditioning), electrical, plumbing, and structural plans
and specifications ("Working Drawings") prepared by Hydzik Schade Associates,
Ltd. necessary to complete the work depicted on the Preliminary Plans and to
obtain a building permit and other governmental approvals for commencement of
the improvements shown thereon. Tenant, at Landlord's cost chargeable against
the Planning Allowance, shall pay for the cost of preparing the Working
Drawings.

     Landlord shall review the Working Drawings and grant its consent thereto
(or disapproval of the Working Drawings thereof) within five (5) business days
after receipt thereof, which approval shall not be unreasonably withheld.
Failure by Landlord to disapprove the Working Drawings within said five (5)
business day period shall be deemed an approval by Landlord of the Working
Drawings. If Landlord disapproves the Working Drawings as aforesaid, Landlord
shall state with specificity Landlord's reason for disapproval. Tenant shall
then modify the Working Drawings to satisfy Landlord's objections and resubmit
the Working Drawing to Landlord for its consent or denial, which resubmittal
shall be accomplished within five (5) business days. The foregoing procedure
shall be followed until final Landlord approval of the Working Drawings. The
final Working Drawings approved by Landlord shall be herein referred to as the

     6. ALLOWANCE. Landlord agrees to pay for the cost of the Tenant
Improvements (the "Basic Project Costs") in an amount not to exceed Seven
