3. LICENSE RESTRICTIONS AND LICENSEE RESPONSIBILITIES.

3.1 DEVELOPMENT RESTRICTIONS. The development rights granted to Licensee in
Section 2.1 may only be exercised by individual developers employed by or under
contract to Licensee that Licensee has designated as "Licensed Developers" and
for whom Licensee has paid the applicable per product or per module development
license fees. If one Licensed Developer ceases to be employed by or under
contract to Licensee or permanently ceases work on projects involving the
Licensed Software, then Licensee may designate an alternate developer to replace
such Licensed Developer at no additional cost. However, the development license
is not a concurrent license that may be used by numerous developers in shifts.
Licensee may not create a programmatic interface that makes use of the Licensed
Software application programming interfaces for use by any party other than
Licensed Developers and must ensure that persons other than Licensed Developers
do not have programmatic access to the Licensed Software or RW Libraries either
directly or indirectly. Nothing herein shall grant Licensee the right to grant
its customers the right to programmatically use or grant others the right to
programmatically use the Licensed Software or RW Libraries.

3.2 GENERAL USE LIMITATIONS. All rights not specifically granted herein are
retained by Rogue Wave. Licensee may not, nor may Licensee permit any other
person or entity to use, copy, modify, or distribute the Licensed Software
(electronically or otherwise), or any copy, adaptation, transcription, or merged
portion thereof (including the RW Libraries), or the Documentation except as
expressly authorized by Rogue Wave. Licensee may not modify or port the Licensed
Software or RW Libraries to operate on or deploy the RW Libraries or
Applications on platforms other than those for which it has paid the appropriate
fees. Licensee may not, nor may Licensee permit any other person or entity to,
reverse assemble, reverse compile, or otherwise translate any binary forms of
the Licensed Software, except to the extent applicable laws specifically
prohibit such restriction. Licensee's rights may not be transferred, leased,
assigned, or sublicensed except for a transfer of the License Agreement in its
entirety to (1) a successor in interest of Licensee's entire business who
assumes the obligations of this License Agreement or (2) any other party who is
reasonably acceptable to Rogue

Rogue Wave Stingray License Terms and Conditions (Rev. 10-June-2003)
<PAGE>

Wave, enters into a substitute version of this License Agreement, and pays an
administrative fee intended to cover attendant costs. No service bureau work,
multiple-user license, or time-sharing arrangement is permitted, except as
expressly authorized by Rogue Wave. If Licensee uses, copies, or modifies the
Licensed Software or RW Libraries or transfers possession of any copy,
adaptation, transcription, or merged portion thereof to any other party in any
way not expressly authorized by Rogue Wave, all licenses under this License
Agreement are automatically terminated.

3.3 PROPRIETARY PROTECTION. Rogue Wave shall have sole and exclusive ownership
of all right, title, and interest in and to the Licensed Software and all
modifications and enhancements thereof (including ownership of all trade secrets
and copyrights pertaining thereto), subject only to the rights and privileges
expressly granted to Licensee herein by Rogue Wave. This License Agreement does
not provide Licensee with title or ownership of the Licensed Software, but only
a right of limited use. Licensee must keep the Licensed Software free and clear
of all claims, liens, and encumbrances.

3.4 COMPLIANCE VERIFICATION. Licensee must have a commercially-reasonable
process in place to track the number of developers using the Licensed Software
in order to ensure that the appropriate license fees have been paid. Licensee
will, upon Rogue Wave's request, certify in writing the number developers using
the Licensed Software, on a per product or per module basis, as of the date of
the request. In the event Licensee fails to provide such certification within
thirty (30) days of Rogue Wave's request, or, if Rogue Wave reasonably believes
that a certification provided by Licensee is inaccurate or that Licensee is
otherwise not in compliance with the terms of this License Agreement, Licensee
will permit Rogue Wave, or a mutually-approved independent representative, to
enter Licensee's premises, during regular business hours, to verify Licensee's
compliance with the terms of this License Agreement.

3.5 CONFIDENTIALITY OF SOURCE CODE. Licensee agrees to maintain in confidence
the source code version of the Licensed Software by using at least the same
physical and other security measures as Licensee uses for its own confidential
technical information and documentation, but in no case less than reasonable
measures. Licensee further agrees not to disclose the source code version of the
Licensed Software, or any aspect thereof (including, without limitation, header
files), to anyone other than employees or contractors who have a need to know or
obtain access to such information in order to support Licensee's authorized use
of the Licensed Software and are bound to protect such information against any
other use or disclosure. These obligations shall not apply to any information
generally available to the public, ascertainable based on the operation of the
binary code version of Applications, independently developed or obtained without
reliance on Rogue Wave's information, or approved for release by Rogue Wave
without restriction.

3.6 DEVELOPMENT OF APPLICATIONS. The Licensed Software is intended for use by
sophisticated developers. Licensee is responsible for selecting persons who are
qualified to use the Licensed Software on Licensee's own equipment and are
familiar with the Licensed Software. Licensee is also responsible for ensuring a
proper environment and proper utilities for the development and execution of
Applications utilizing the Licensed Software. Licensee represents that it has
the requisite expertise to evaluate the suitability of the Licensed Software and
that it has undertaken its own investigation of the suitability of the Licensed
Software in the Applications. Licensee represents that it has relied upon its
own skill and judgment in selecting the Licensed Software and developing the
Applications.

3.7 RELATIONSHIP WITH END USERS. There are no third party beneficiaries to this
License Agreement. Consequently, Rogue Wave provides no warranty at all to any
person, other than the limited warranty provided to Licensee hereunder. Licensee
will be solely responsible for the development of the Applications authorized by
this License Agreement and for providing all support or services required or
requested by end users of the Applications. Licensee will not make any
representations or warranties to its employees, customers, end users or any
other third party on Rogue Wave's behalf. Rogue Wave assumes no responsibility
under this License Agreement, either directly or indirectly, for damages to
Licensee or third parties resulting from the direct or indirect use of the
Applications created by or on behalf of Licensee and Licensee shall defend and
hold harmless Rogue Wave from any such damages. Licensee hereby agrees to
indemnify and hold harmless Rogue Wave from and against any and all claims,
actions, or demands arising with respect to Applications developed and/or
distributed by Licensee, with the sole exception of those matters for which
Rogue Wave bears responsibility under Section 6 of this License Agreement. The
foregoing indemnity shall be contingent upon Rogue Wave: (1) giving written
notice to the Licensee of any claim, demand, or action for which indemnity is
sought; (2) fully cooperating in the defense or settlement of any such claim,
demand, or action; and (3) obtaining the prior written agreement of (he Licensee
to any settlement or proposal of settlement.

3.8 REMEDIES. Licensee acknowledges that, in the event of Licensee's breach of
any of the foregoing provisions, Rogue Wave will not have an adequate remedy in
money or damages. Rogue Wave will therefore be entitled to obtain an injunction
against such breach from any court of competent jurisdiction immediately upon
request without posting a bond. Rogue Wave's right to obtain injunctive relief
shall not limit its right to seek further remedies.

4. MAINTENANCE AND SUPPORT OF LICENSED SOFTWARE. Rogue Wave or its authorized
resellers shall provide Maintenance and Support on the Licensed Software at the
level and for the period for which Licensee has paid the applicable fees.
Maintenance and Support services provided by Rogue Wave are provided in
accordance with Rogue Wave's Stingray maintenance and support and obsolescence
policies, which are subject to change. Maintenance and Support is limited to
platforms listed on Rogue Wave's current product support matrix, which is also
subject to change. Licensee is responsible for ensuring that its development and
deployment environment is on the current product support matrix. Off-matrix
support is available from Rogue Wave for an additional fee. At the end of any
maintenance and support period, Rogue Wave or its authorized reseller may send
Licensee a pro forma invoice for renewal of maintenance and support. Licensee
may renew maintenance and support for the period set forth in such pro forma
invoice by paying the fees set forth therein. If Licensee fails to pay the fees
set forth in the pro forma invoice by the end of the then current maintenance
and support period, then maintenance and support shall terminate as of the end
of such period.

5. LIMITED WARRANTY, DISCLAIMER AND LIMITATION OF LIABILITY.

5.1 LIMITED WARRANTY. Rogue Wave warrants to Licensee that the unaltered
Licensed Software, when used as permitted under the License Agreement and in
accordance with the instructions in the Documentation, will operate
substantially as described in the Documentation for a period of sixty (60) days
from the date of delivery (the "Software Warranty Period"). The Licensed
Software is provided to Licensee as source code and is for use by sophisticated
software developers, and Rogue Wave does not warrant that use of the Licensed
Software will be uninterrupted or error-free, that all errors will be corrected,
or that use of the Licensed Software will meet Licensee's needs. Rogue Wave
will, at its own expense and as its sole obligation and Licensee's sole and
exclusive remedy for any breach of this warranty, use commercially reasonable
efforts to correct any reproducible error in the Licensed Software reported to
Rogue Wave by Licensee in writing during the Software Warranty Period; provided,
however, that no such error correction provided to Licensee will extend the
original Software Warranty Period. If Rogue Wave determines that it is unable to
correct the error, Rogue Wave may, upon approval by Licensee, refund to Licensee
the fees paid by the Licensee for the defective Licensed Software and terminate
the License Agreement and all licenses granted herein. In the event Licensee
does not approve of such refund and termination of the License Agreement,
Licensee will be entitled to keep the Licensed Software and use it pursuant to
the licenses granted herein; provided, however, that Rogue Wave will not be
obligated to provide Maintenance and Support for the Licensed Software that is
impacted by the reported defect.

5.2 EXCLUSIONS. The limited warranty set forth above will not apply to defects
resulting from, or because of, modifications made to the Licensed Software by
anyone other than Rogue Wave, misuse, failure of media not furnished by Rogue
Wave, operation with media, software or equipment not authorized by Rogue Wave
in the Documentation or not meeting or not maintained in accordance with the
supplier's specifications, or causes other than ordinary use. The warranty set
forth above will not be enlarged, diminished or affected by, and no obligation
or liability will arise from, Rogue Wave's rendering of technical advice,
assistance or service in connection with Licensee's selection or use of the
Licensed Software.

5.3 DISCLAIMER. EXCEPT FOR THE LIMITED WARRANTY SET FORTH IN SECTION 5.1 ABOVE,
THE LICENSED SOFTWARE IS PROVIDED "AS IS," WITHOUT REPRESENTATIONS OR WARRANTIES
OF ANY KIND. ROGUE WAVE SPECIFICALLY DISCLAIMS ALL OTHER PROMISES,
REPRESENTATIONS OR WARRANTIES, EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED
TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE,
TITLE AND NON-INFRINGEMENT, AND ANY IMPLIED WARRANTY ARISING FROM COURSE OF
PERFORMANCE OR COURSE OF DEALING.

5.4 LIMITATION OF LIABILITY. THE CUMULATIVE LIABILITY OF ROGUE WAVE TO LICENSEE
FOR ALL CLAIMS RELATING TO THE LICENSED SOFTWARE AND THIS LICENSE AGREEMENT,
INCLUDING ANY CAUSE OF ACTION SOUNDING IN CONTRACT, TORT, OR STRICT LIABILITY,
SHALL NOT EXCEED THE TOTOL AMOUNT OF ALL LICENSE FEES PAID TO ROGUE WAIVE
HEREUNDER. THIS LIMITATION OF LIABILITY IS INTENDED TO APPLY WITHOUT REGARD TO
WHETHER OTHER PROVISIONS OF THIS LICENSE AGREEMENT HAVE BEEN BREACHED OR HAVE
PROVEN INEFFECTIVE. THIS LIMITATION OF LIABILITY SHALL NOT APPLY TO THE
INDEMNIFICATION PROVIDED IN SECTION 6 HEREOF. ROGUE WAVE SHALL HAVE NO LIABILITY
FOR LOSS OF DATA OR DOCUMENTATION, IT BEING UNDERSTOOD THAT LICENSEE IS
RESPONSIBLE FOR REASONABLE BACK-UP PRECAUTIONS. IN NO EVENT SHALL ROGUE WAVE BE
LIABLE FOR ANY LOSS OF PROFITS; ANY INCIDENTAL, SPECIAL, EXEMPLARY, OR
CONSEQUENTIAL DAMAGES; OR ANY CLAIMS OR DEMANDS BROUGHT AGAINST LICENSEE, EVEN
IF ROGUE WAVE HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH CLAIMS OR DEMANDS.
THIS LIMITATION UPON DAMAGES AND CLAIMS IS INTENDED TO APPLY WITHOUT REGARD TO
WHETHER OTHER PROVISIONS OF THIS LICENSE AGREEMENT HAVE BEEN BREACHED OR HAVE
PROVEN INEFFECTIVE. LICENSEE MAY HAVE ADDITIONAL RIGHTS UNDER CERTAIN LAWS
(E.G., CONSUMER LAWS) THAT DO NOT ALLOW THE EXCLUSION OF IMPLIED WARRANTIES, OR
THE EXCLUSION OR LIMITATION OF CERTAIN DAMAGES. IF SUCH LAWS APPLY, CERTAIN
EXCLUSIONS OR LIMITATIONS MAY NOT APPLY TO LICENSEE; HOWEVER, ALL OTHER
RESTRICTIONS AND LIMITATIONS SHALL REMAIN IN EFFECT.

6. INDEMNIFICATION. If a third party claims that the Licensed Software infringes
its patent, copyright, or trade secret, or any similar intellectual property
right, Rogue Wave will defend Licensee against that claim at Rogue Wave's
expense and pay all damages that a court finally awards, provided that Licensee
promptly notifies Rogue Wave in writing of the claim, and allows Rogue Wave to
control, and cooperates with Rogue Wave in, the defense or any related
settlement negotiations. If such a claim is made or appears possible, Licensee
agrees to permit Rogue Wave to enable Licensee to continue to use the Licensed
Software, or to modify or replace it. If Rogue Wave determines that none of
these alternatives is reasonably available, Licensee will agree to return the
Licensed Software on Rogue Wave's written request, and Licensee will then
receive a credit equal to the net book value for the Licensed Software
determined in accordance with generally accepted accounting principles. However,
Rogue Wave has no obligation for any claim based on Licensee's modification of
the Licensed Software or its combination, operation, or use with any product,
data, or apparatus not specified or provided by Rogue Wave, provided that such
claim solely and necessarily is based on such combination, operation, or use,
and such claim would be avoided by combination, operation, or use with products,
data, or apparatus specified or provided by Rogue Wave. THIS PARAGRAPH STATES
ROGUE WAVE'S ENTIRE OBLIGATION TO LICENSEE WITH RESPECT TO ANY CLAIM OF
INFRINGEMENT.

7. TERMINATION.

7.1 TERM. The term of this License Agreement will begin as of the date that
Licensee receives the Licensed Software and will remain in effect perpetually
unless terminated under this Section 7.

7.2 TERMINATION FOR CAUSE. Rogue Wave may terminate this License Agreement if
Licensee breaches its obligations hereunder. Rogue Wave will effect such
termination by giving Licensee notice of termination, specifying therein the
alleged breach. If the breach is curable, Licensee will have a grace period of
thirty (30) days after such notice is served to cure the breach described
therein. If the breach is cured within the thirty (30) day grace period, then
this License Agreement will remain in effect; otherwise, this License Agreement
will automatically terminate upon the conclusion of the thirty (30) day grace
period.

7.3 EFFECT OF TERMINATION. Upon termination of the License Agreement for any
reason the following terms shall apply: (a) all rights granted under this
License Agreement will immediately terminate and Licensee must immediately stop
all use of the Licensed Software; (b) Licensee must return to Rogue Wave or
destroy all copies of the Licensed Software provided to or made by or on behalf
of Licensee, and will, within ten (10) days after the effective date of
termination, provide Rogue Wave with written certification that all such copies
have been returned or destroyed; and (c) all provisions of this License
Agreement with the exception of the licenses granted in Section 2 and
Maintenance and Support obligations set forth in Section 4 will survive
termination of this License Agreement for any reason. Termination of the License
Agreement will not affect Licensee's obligation to pay all amounts accrued
hereunder prior to the effective date of termination.

8. MISCELLANEOUS.

8.1 SEVERABILITY. If any term or provision of the License Agreement is found to
be invalid under any applicable statute or rule of law, then, that provision
notwithstanding, the License Agreement will remain in full force and effect, and
in such event, such provision will be changed and interpreted so as to best
accomplish the objectives of such unenforceable or invalid provision within the
limits of applicable law or applicable court decisions.

8.2 GOVERNING LAW/FORUM SELECTION. The License Agreement and the parties' rights
and obligations hereunder shall be solely and exclusively construed, interpreted
and enforced under and in accordance with the laws of the State of Colorado,
United States of America, without any reference to conflicts of law principles.
The parties agree that the U.N. Convention on the International Sale of Goods
shall not apply to the License Agreement. Any and all disputes between the
parties that cannot be amicably resolved, arising under, out of, or otherwise
relating to the License Agreement, Licensed Software or any services provided by
Rogue Wave to Licensee shall be brought and resolved solely and exclusively in
the state or federal courts located in the State of Colorado, United States of
America. Both parties hereby irrevocably consent to the jurisdiction of such
courts and service of process in connection therewith. Any judgment rendered by
such courts may be entered and enforced by any court having jurisdiction over
the party against which an award is entered or its assets. Both parties hereby
irrevocably waive any objections to the jurisdiction of such courts based on any
ground, including without limitation improper venue or forum non conveniens.

8.3 NO JOINT VENTURE. Nothing contained in the License Agreement will be
construed so as to make the parties partners or joint venturers or to permit
either party to bind the other party to any agreement or purport to act on
behalf of the other party in any respect.

8.4 WAIVER AND MODIFICATIONS. Failure by either party to enforce any rights
under this License Agreement will not be construed as a waiver of such rights,
and a waiver by either party of a default hereunder in one or more instances
will not be construed as constituting a continuing waiver or as a waiver in
other instances. No modification of this License Agreement shall be binding
unless it is in writing and is signed by an authorized representative of the
party against whom enforcement of the modification is sought.

8.5 IMPORT/EXPORT LAW. Licensee may not import, use or otherwise export or
re-export the Licensed Software except as authorized by United States law and
the laws of the jurisdiction in which the Licensed Software was obtained.

8.6 TAXES. License fees and Maintenance and Support fees are exclusive of, and

event CC&R's are subsequently implemented, Landlord shall provide a copy of said

      2. TERM

      A.    The Term of this Lease shall be for a period of FIVE (5) YEARS
(unless sooner terminated as hereinafter provided) and, subject to Paragraphs
2B, 2C and 3, SHALL COMMENCE ON THE 1ST DAY OF SEPTEMBER, 2001 (THE

      B.    Possession of the Premises shall be tendered by Landlord to Tenant
and the Term of the Lease shall commence on September 1, 2001 or as otherwise

      C.    Lease Contingent Upon Landlord Obtaining Termination Agreement with
Current Tenant: This Lease is subject to and conditional upon Landlord obtaining
from Centura Corporation ("Centura"), the current tenant occupying the Premises
leased hereunder, a Termination Agreement related to the Premises satisfactory
to Landlord on or before August 31, 2001. In the event Landlord is unable to
obtain said satisfactory Termination Agreement on or before August 31, 2001,
this Lease Agreement shall, at Landlord's option (a) be rescinded, or (b) the
Commencement Date hereof shall be modified to reflect the date Landlord so
obtains said satisfactory Termination Agreement and receives possession of the
Premises hereunder free and clear of Centura's occupancy; provided, however,
that said period of delay caused by Centura shall not extend beyond October 31,
2001. In the event this Lease does not commence by November 1, 2001 (subject
only to the delays covered in Paragraph 3) this Lease shall be automatically
rescinded.

      It is agreed in the event said Lease commences on a date other than the
first day of the month the Term of the Lease will be extended to account for the
number of days in the partial month. The Basic Rent during the resulting partial
month will be pro-rated (for the number of days in the partial month) at the
Basic Rent rate scheduled for the projected Commencement Date as shown in
Paragraph 4A.

      3. POSSESSION. If Landlord, for any reason whatsoever, cannot deliver
possession of said Premises to Tenant at the commencement of the said Term, as
hereinbefore specified, this Lease shall not be void or voidable; no obligation
of Tenant shall be affected thereby; nor shall Landlord or Landlord's agents be
liable to Tenant for any loss or damage resulting therefrom; but in that event
the commencement and termination dates of the Lease, and all other dates
affected thereby shall be revised to conform to the date of Landlord's delivery
of possession, as specified in Paragraph 2B above. The above is, however,
subject to the provision that the period of delay of delivery of the Premises
shall not exceed sixty (60) days from the Commencement Date herein (except those
delays caused by Acts of God, strikes, war, utilities, governmental bodies,
weather, unavailable materials, and delays beyond Landlord's control shall be
excluded in calculating such period) in which instance Tenant, at its option,
may, by written notice to Landlord, terminate this Lease; provided Tenant
submits said notice to Landlord prior to the expiration of said 60 day period.

      C.    Late Charge. Notwithstanding any other provision of this Lease, if

Landlord elects to do so at Landlord's sole and absolute discretion as compared
to Landlord's actual expenditure for said Additional Rent items, with Tenant
paying to Landlord, upon demand, any amount of actual expenses expended by
Landlord in excess of said estimated amount, or Landlord crediting to Tenant
(providing Landlord may withhold any amount thereof required to cure Tenant's
default in the performance of any of the terms, covenants and conditions of this
Lease) any amount of estimated payments made by Tenant in excess of Landlord's
actual expenditures for said Additional Rent Items. Within thirty (30) days
after receipt of Landlord's reconciliation, Tenant shall have the right, at
Tenant's sole expense, to audit, at a mutually convenient time at Landlord's
office, Landlord's records specifically limited to the foregoing expenses. Such
audit must be conducted by Tenant or an independent nationally recognized
accounting firm that is not being compensated by Tenant or other third party on
a contingency fee basis. Tenant shall submit to Landlord a complete copy of said
audit at no expense to Landlord and a written notice stating the results of said
audit, and if such notice by Tenant and the respective audit reveals that
Landlord has overcharged Tenant, and the audit is not challenged by Landlord,
the amount overcharged shall be credited to Tenant's account within thirty (30)
days after completion of Landlord's review and approval of said audit.

      E.    Fixed Management Fee. Beginning with the Commencement Date of the
Term of this Lease, Tenant shall pay to Landlord, in addition to the Basic Rent
and Additional Rent, a fixed monthly management fee ("Management Fee") equal to
three percent (3%) of the Basic Rent due for each month during the Lease Term.
Said Management Fee shall be paid by Tenant to A&P Property Management Company
at 2560 Mission College Blvd., Suite 101, Santa Clara, California 95054.

      The reference to "Rent" in this Paragraph 4 includes Basic Rent,
Additional Rent, and fixed Management Fee. The respective obligations of
Landlord and Tenant under this Paragraph shall survive the expiration or other
termination of the Term of this Lease, and if the Term hereof shall expire or
shall otherwise terminate on a day other than the last day of a calendar year,
the actual Additional Rent incurred for the calendar year in which the Term
hereof expires or otherwise terminates shall be determined and settled on the
basis of the statement of actual Additional Rent for such calendar year and
shall be prorated in the proportion which the number of days in such calendar
year preceding such expiration or termination bears to 365.

      F.    Place of Payment of Rent. All Rent hereunder shall be paid to
Landlord at the office of Landlord at: WESTPORT JOINT VENTURE, 2560 MISSION
COLLEGE BLVD., SUITE 101, SANTA CLARA, CA 95054, or to such other person or to
such other place as Landlord may from time to time designate in writing.

      G.    Security Deposit. Concurrently with Tenant's execution of this
Lease, Tenant shall deposit with Landlord the sum of THIRTY NINE THOUSAND EIGHT
HUNDRED NINE AND 70/100 Dollars ($39,809.70). Said sum shall be held by Landlord
as a Security Deposit for the faithful performance by Tenant of all of the
terms, covenants, and conditions of this Lease to be kept and performed by
Tenant during the Term hereof. If Tenant defaults with respect to any provision
of this Lease, including, but not limited to, the provisions relating to the
payment of Rent and any of the monetary sums due herewith, Landlord may (but
shall not be required to) use, apply or retain all or any part of this Security
Deposit for the payment of any other amount which Landlord may 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 said
Deposit is so used or applied, Tenant shall, within ten (10) days after written
demand therefor, deposit cash with Landlord in the amount sufficient to restore
the Security Deposit to its original amount. Tenant's failure to do so shall be
a material breach of this Lease. Landlord shall not be required to keep this
Security Deposit separate from its general funds, and Tenant shall not be
entitled to interest on such 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) at the expiration of the Lease
Term and after Tenant has vacated the Premises; provided, however, that Landlord
may withhold therefrom the amount necessary to cover the cost of restoration of
the Premises if Tenant fails to do so as required under Lease Paragraph 8 and to
cure any then uncured default by Tenant under this Lease. In the event of
termination of Landlord's interest in this Lease, Landlord shall transfer said
Deposit to Landlord's successor in interest whereupon Tenant agrees to release
Landlord from liability for the return of such Deposit or the accounting
therefor.

      5. RULES AND REGULATIONS AND COMMON AREA. Subject to the terms and
conditions of this Lease and such Rules and Regulations as Landlord may from
time to time prescribe, Tenant and Tenant's employees, invitees and customers

to the use of the Common Area, and any part or parts thereof, as Landlord may
deem appropriate for the best interests of the occupants of the Complex. The

occupants of the Complex twenty eight (28) parking spaces in the common parking
areas of the Complex. Tenant agrees that Tenant, Tenant's employees, agents,
representatives and/or invitees shall not use parking spaces in excess of said
28 spaces allocated to Tenant hereunder. Landlord shall have the right, at
Landlord's sole discretion, to specifically designate the location of Tenant's
parking spaces within the common parking areas of the Complex in the event of a
dispute among the tenants occupying the building and/or Complex referred to
herein, in which event Tenant agrees that Tenant, Tenant's employees, agents,
representatives and/or invitees shall not use any parking spaces other than
those parking spaces specifically designated by Landlord for Tenant's use. Said
parking spaces, if specifically designated by Landlord to Tenant, may be
relocated by Landlord at any time, and from time to time, Landlord reserves the
right, at Landlord's sole discretion, to rescind any specific designation of
parking spaces, thereby returning Tenant's parking spaces to the common parking
area. Landlord shall give Tenant written notice of any change in Tenant's
parking spaces. Tenant shall not, at any time, park or permit to be parked, any
trucks or vehicles adjacent to the loading areas so as to interfere in any way
with the use of such areas, nor shall Tenant at any time park or permit the
parking of Tenant's trucks or other vehicles or the trucks and vehicles of
Tenant's suppliers or others, in any portion of the common area not designated
by Landlord for such use by Tenant. Tenant shall not park nor permit to be
parked, any inoperative vehicles or equipment on any portion of the common
parking area or other common areas of the Complex. Tenant agrees to assume
responsibility for compliance by its employees with the parking provisions
contained herein. If Tenant or its employees park in other than such designated
parking areas, then Landlord may charge Tenant, as an additional charge, and
Tenant agrees to pay, Ten Dollars ($10.00) per day for each day or partial day
each such vehicle is parked in any area other than that designated. Tenant
hereby authorizes Landlord at Tenant's sole expense to tow away from the Complex
any vehicle belonging to Tenant or Tenant's employees parked in violation of
these provisions, or to attach violation stickers or notices to such vehicles.
Tenant shall use the parking spaces for vehicle parking only and shall not use
the parking areas for storage.

as a merger and, at the option of Landlord, shall either terminate all or any
existing subleases or subtenancies or operate as an assignment to Landlord of
all or any such subleases or subtenancies.

      9. "AS-IS" BASIS. It is hereby agreed that the Premises leased hereunder
is leased strictly on an "as-is" basis and in its present condition, and in the
configuration as shown on Exhibit B attached hereto, and by reference made a
part hereof. It is specifically agreed between the parties that Landlord shall
not be required to make, nor be responsible for any cost, in connection with any
repair, restoration, and/or improvement to the Premises in order for this Lease
to commence, or thereafter, throughout the Term of this Lease. Notwithstanding
anything to the contrary within this Lease, Landlord makes no warranty or
representation of any kind or nature whatsoever as to the condition or repair of
the Premises, nor as to the use or occupancy which may be made thereof.

      10. ALTERATIONS AND ADDITIONS. Tenant shall not make, or suffer to be
made, any alteration or addition to the Premises, or any part thereof, without
the written consent of Landlord first had and obtained by Tenant (such consent
not to be unreasonably withheld), but at the cost of Tenant, and any addition
to, or alteration of, the Premises, except moveable furniture and trade
fixtures, shall at once become a part of the Premises and belong to Landlord.
Landlord reserves the right to approve all contractors and mechanics proposed by
Tenant to make such alterations and additions. As a condition to Landlord
granting its consent to any alterations, Tenant shall deliver plans and
specifications for Landlord's review and approval, and within five business days
of completion of said alterations, Tenant shall deliver to Landlord an original
1/8" scaled sepia or an other electronic format as solely determined by
Landlord. Tenant shall retain title to all moveable furniture and trade fixtures
placed in the Premises. All heating, lighting, electrical, air conditioning,
security systems, floor to ceiling partitioning, drapery, carpeting, and floor
installations made by Tenant, together with all property that has become an
integral part of the Premises, shall not be deemed trade fixtures. Tenant agrees
that it will not proceed to make such alteration or additions, without having
obtained consent from Landlord to do so, and until five (5) days from the
receipt of such consent, in order that Landlord may post appropriate notices to
avoid any liability to contractors or material suppliers for payment for
Tenant's improvements. Tenant will at all times permit such notices to be posted
and to remain posted until the completion of work. Tenant shall, if required by
Landlord, secure at Tenant's own cost and expense, a completion and lien
indemnity bond, satisfactory to Landlord, for such work. Tenant further
covenants and agrees that any mechanic's lien filed against the Premises for
work claimed to have been done for, or materials claimed to have been furnished
to Tenant, will be discharged by Tenant, by bond or otherwise, within ten (10)
days after notice of filing thereof, at the cost and expense of Tenant. Any
exceptions to the foregoing must be made in writing and executed by both
Landlord and Tenant. Notwithstanding anything to the contrary herein, under no
circumstances shall Tenant be authorized to penetrate the soil to a depth that
exceeds three and one-half feet from the uppermost surface of the soil.

      11. TENANT MAINTENANCE. Tenant shall, at its sole cost and expense, keep
and maintain the Premises (including appurtenances) and every part thereof in a
high standard of maintenance and repair, and in good and sanitary condition.
Tenant's maintenance and repair responsibilities herein referred to include, but
are not limited to, janitorization, plumbing systems within the non-common areas
of the Premises (such as water and drain lines, sinks), electrical systems
within the non-common areas of the Premises (such as outlets, lighting fixtures,
lamps, bulbs, tubes, ballasts), heating and air-conditioning controls within the
non-common areas of the Premises (such as mixing boxes, thermostats, time
clocks, supply and return grills), non-common elevators (if any), and all
interior improvements within the Premises including but not limited to: wall
coverings, window coverings, acoustical ceilings, vinyl tile, carpeting,
partitioning, doors (both interior and exterior, including closing mechanisms,
latches, locks), skylights (if any), automatic fire extinguishing systems, and
all other interior improvements of any nature whatsoever. Tenant agrees to
provide carpet shields under all rolling chairs or to otherwise be responsible
for wear and tear of the carpet caused by such rolling chairs if such wear and
tear exceeds that caused by normal foot traffic in surrounding areas. Areas of
excessive wear shall be replaced at Tenant's sole expense upon Lease
termination. Tenant hereby waives all rights hereunder, and benefits of,
subsection 1 of Section 1932 and Sections 1941 and 1942 of the California Civil
Code and under any similar law, statute or ordinance now or hereafter in effect.

      12. UTILITIES OF THE BUILDING IN WHICH THE PREMISES ARE LOCATED. As
Additional Rent and in accordance with Paragraph 4D of this Lease Tenant shall
pay its proportionate share (i) calculated on a square footage basis (Tenant's
proportionate share as a percentage of the Building is 13.06% (6,319 square foot
Leased, Premises divided by 48,384 square foot Building) or (ii) other equitable
basis (as calculated by Landlord) of the cost of all utility charges such as
water, gas, electricity, sewer service, waste pick-up and any other utilities,
materials or services furnished directly to the building in which the

Premises are located, including, without limitation, any temporary or permanent
utility surcharge or other exactions whether or not hereinafter imposed.

Landlord shall not be liable for and Tenant shall not be entitled to any
abatement or reduction of rent by reason of any interruption or failure of
utility services to the Premises when such interruption or failure is caused by
accident, breakage, repair, strikes, lockouts, or other labor disturbances or
labor disputes of any nature, or by any other cause, similar or dissimilar,
beyond the reasonable control of Landlord.

Provided that Tenant is not in default in the performance or observance of any
of the terms, covenants or conditions of this Lease to be performed or observed
by it, Landlord shall furnish to the Premises between the hours of 8:00 am and
6:00 pm, Mondays through Fridays (holidays excepted) and subject to the rules
and regulations of the Common Area hereinbefore referred to, reasonable
quantities of water, gas and electricity suitable for the intended use of the
Premises and heat and air-conditioning required in Landlord's judgment for the
comfortable use and occupation of the Premises for such purposes. Tenant agrees
that at all times it will cooperate fully with Landlord and abide by all
regulations and requirements that Landlord may prescribe for the proper
functioning and protection of the building heating, ventilating and
air-conditioning systems. Whenever heat generating machines, equipment, or any
other devices (including exhaust fans) are used in the Premises by Tenant which
affect the temperature or otherwise maintained by the air-conditioning system,
Landlord shall have the right to install supplementary air-conditioning units in
the Premises and the cost thereof, including the cost of installation and the
cost of operation and maintenance thereof, shall be paid by Tenant to Landlord
upon demand by Landlord. Tenant will not, without the written consent of
Landlord, use any apparatus or device in the Premises (including, without
limitation), electronic data processing machines or machines using current in
excess of 110 Volts which will in any way increase the amount of electricity,
gas, water or air-conditioning usually furnished or supplied to premises being
used as general office space, or connect with electric current (except through
existing electrical outlets in the Premises), or with gas or water pipes any
apparatus or device for the purposes of using electric current, gas, or water.
If Tenant shall require water, gas, or electric current in excess of that
usually furnished or supplied to premises being used as general office space,
Tenant shall first obtain the written consent of Landlord, which consent shall
not be unreasonably withheld and Landlord may cause an electric current, gas or
water meter to be installed in the Premises in order to measure the amount of
electric current, gas or water consumed for any such excess use. The cost of any
such meter and of the installation, maintenance and repair thereof, all charges
for such excess water, gas and electric current consumed (as shown by such
meters and at the rates then charged by the furnishing public utility); and any
additional expense incurred by Landlord in keeping account of electric current,
gas, or water so consumed shall be paid by Tenant, and Tenant agrees to pay
Landlord therefor promptly upon demand by Landlord.

      13. TAXES.

      A.    As Additional Rent and in accordance with Paragraph 4D of this
Lease, Tenant shall pay to Landlord, monthly in advance or as they become due,
pursuant to statements submitted by Landlord, Tenant's proportionate share (i)
calculated on a square footage basis (Tenant's proportionate share as a
percentage of the Building is 13.06% (6,319 square foot Leased, Premises divided
by 48,384 square foot Building) or (ii) other equitable basis, (as calculated by
Landlord) of all Real Property Taxes relating to the Premises accruing with
respect to the Premises during the Term of this Lease and the Extended Term (if
any). The term "Real Estate Taxes" shall also include supplemental taxes related
to the period of Tenant's Lease Term whenever levied, including any such taxes
that may be levied after the Lease Term has expired. The term "Real Property
Taxes", as used herein, shall mean (i) all taxes, assessments, levies and other
charges of any kind or nature whatsoever, general and special, foreseen and
unforeseen (including all installments of principal and interest required to pay
any general or special assessments for public improvements and any increases
resulting from reassessments caused by any change in ownership of the Premises)
now or hereafter imposed by any governmental or quasi-governmental authority or
special district having the direct or indirect power to tax or levy assessments,
which are levied or assessed against, or with respect to the value, occupancy or
use of, all or any portion of the Complex (as now constructed or as may at any
time hereafter be constructed, altered, or otherwise changed) or Landlord's
interest therein; any improvements located within the Complex (regardless of
ownership); the fixtures, equipment and other property of Landlord, real or
personal, that are an integral part of and located in the Complex; or parking
areas, public utilities, or energy within the Complex; (ii) all charges, levies
or fees imposed by reason of environmental regulation or other governmental
control of the Complex and (iii) all costs and fees (including reasonable
attorneys' fees) incurred by Landlord in reasonably contesting any Real Property
Tax and in negotiating with public authorities as to any Real Property Tax. If
at any time during the Term of this Lease the taxation or assessment of the
Complex prevailing as of the Commencement Date of this Lease shall be altered so
that in

lieu of or in addition to any Real Property Tax described above there shall be
levied, assessed or imposed (whether by reason of a change in the method of
taxation or assessment, creation of a new tax or charge, or any other cause) an
alternate or additional tax or charge (i) on the value, use or occupancy of the
Complex o Landlord's interest therein or (ii) on or measured by the gross
receipts, income or rentals from the Complex, on Landlord's business of leasing
the Complex, or computed in any manner with respect to the operation of the
Complex, then any such tax or charge, however designated, shall be included
within the meaning of the term "Real Property Taxes" for purposes of this Lease.
If any Real Property Tax is based upon property or rents unrelated to the
Complex, then only that part of such Real Property Tax that is fairly allocable
to the Complex shall be included within the meaning of the term "Real Property
Taxes." Notwithstanding the foregoing, the term "Real Property Taxes" shall not
include estate, inheritance, gift or franchise taxes of Landlord or the federal
or state net income tax imposed on Landlord's income from all sources.

            Taxes on Tenant's Property.

      (a) Tenant shall be liable for and shall pay ten days before delinquency,
taxes levied against any personal property or trade fixtures placed by Tenant in
or about the Premises. If any such taxes on Tenant's personal property or trade
fixtures are levied against Landlord or Landlord's property or if the assessed
value of the Premises is increased by the inclusion therein of a value placed
upon such personal property or trade fixtures of Tenant and if Landlord, after
written notice to Tenant, pays the taxes based on such increased assessment,
which Landlord shall have the right to do regardless of the validity thereof,
but only under proper protest if requested by Tenant, Tenant shall upon demand,
as the case may be, repay to Landlord the taxes so levied against Landlord, or
the proportion of such taxes resulting from such increase in the assessment;
provided that in any such event Tenant shall have the right, in the name of
Landlord and with Landlord's full cooperation, to bring suit in any court of
competent jurisdiction to recover the amount of such taxes so paid under
protest, and any amount so recovered shall belong to Tenant.

      (b) If the Tenant improvements in the Premises, whether installed, and/or
paid for by Landlord or Tenant and whether or not affixed to the real property
so as to become a part thereof, are assessed for real property tax purposes at a
valuation higher than the valuation at which standard office improvements in
other space in the Complex are assessed, then the real property taxes and
assessments levied against the Landlord or the Complex by reason of such excess
assessed valuation shall be deemed to be taxies levied against personal property
of the Tenant and shall be governed by the provisions of 13B(a) above. If the
records of the County Assessor are available and sufficiently detailed to serve
as a basis for determining whether said Tenant improvements are assessed at a
higher valuation than standard office space improvements in other space in the
Complex, such records shall be binding on both the Landlord and the Tenant. If
the records of the County Assessor are not available or sufficiently detailed to
serve as a basis for making said determination, the actual cost of construction
shall be used.

      14.ASSESSMENT CREDITS. The demised property herein may be subject to a
special assessment levied by the City of Redwood City as part of an Improvement
District. As a part of said special assessment proceedings (if any), additional
bonds were or may be sold and assessments were or may be levied to provide for
construction contingencies and reserve funds. Interest shall be earned on such
funds created for contingencies and on reserve funds which will be credited for
the benefit of said assessment district. To the extent surpluses are created in
said district through unused contingency funds, interest earnings or reserve
funds, such surpluses shall be deemed the property of Landlord. Notwithstanding
that such surpluses may be credited on assessments otherwise due against the
Leased Premises, Tenant shall pay to Landlord, as Additional Rent if, and at the
time of any such credit of surpluses, an amount equal to all such surpluses so
credited net of any payment Tenant may have made to specifically cover the
funding of the contingencies and/or reserve funds. For example: if (i) the
property is subject to an annual assessment of $ 1,000.00, and (ii) a surplus of
$200.00 is credited towards the current year's assessment which reduces the
assessment amount shown on the property tax bill from $1,000.00 to $800.00,
Tenant shall, upon receipt of notice from Landlord, pay to Landlord said $200.00
credit as Additional Rent.

      15.LIABILITY INSURANCE. Tenant, at Tenant's expense, agrees to keep in
force during the Term of this Lease a policy of commercial general liability
insurance with combined single limit coverage of not less than Two Million
Dollars ($2,000,000) per occurrence for injuries to or death of persons
occurring in, on, or about the Premises or the Complex and property damage. Such
insurance shall be primary and noncontributory as respects any insurance carried
by Landlord. The policy or polices affecting such insurance, certificates of
insurance of which shall be furnished to Landlord, shall name Landlord as
additional insureds, and shall insure any liability of Landlord, contingent or
otherwise, as respects acts or omissions of Tenant, its agents, employees or
invitees or otherwise by any conduct or transactions of any of said persons in

or about or concerning the Premises, including any failure of Tenant to observe
or perform any of its obligations hereunder; shall be issued by an insurance
company admitted to transact business in the State of California; and shall
provide that the insurance effected thereby shall not be canceled, except upon
thirty (30) days' prior written notice to Landlord. A certificate of insurance
of said policy shall be delivered to Landlord. If, during the Term of this
Lease, in the considered opinion of Landlord's Lender, insurance advisor, or
counsel, the amount of insurance described in this Paragraph 15 is not adequate,
Tenant agrees to increase said coverage to such reasonable amount as Landlord's
Lender, insurance advisor, or counsel shall deem adequate.

      16.TENANT'S PERSONAL PROPERTY INSURANCE AND WORKMAN'S COMPENSATION
INSURANCE. Tenant shall maintain a policy or policies of fire and property
damage insurance in "all risk" form with a sprinkler leakage endorsement
insuring the personal property, inventory, trade fixtures, and leasehold
improvements within the Leased Premises for the full replacement value thereof.
The proceeds from any of such policies shall be used for the repair or
replacement of such items so insured.

      Tenant shall also maintain a policy or policies of workman's compensation
insurance and any other employee benefit insurance sufficient to comply with all
laws.

      17.PROPERTY INSURANCE. Landlord shall purchase and keep in force, and as
Additional Rent and in accordance with Paragraph 4D of this Lease, Tenant shall
pay to Landlord (or Landlord's agent if so directed by Landlord) Tenant's
proportionate (i) calculated on a square footage basis (Tenant's proportionate
share as a percentage of the Building is 13.06% (6,319 square foot Leased,
Premises divided by 48,384 square foot Building) or (ii) other equitable basis
(as calculated by Landlord) of the deductibles on insurance claims and the cost
of, policy or policies of insurance covering loss or damage to the Premises and
Complex (excluding routine maintenance and repairs and incidental damage or
destruction caused by accidents or vandalism for which Tenant is responsible
under Paragraph 11) in the amount of the full replacement value thereof,
providing protection against those perils included within the classification of
"all risks" insurance and flood and/or earthquake insurance, if available, plus
a policy of rental income insurance in the amount of one hundred (100%) percent
of twelve (12) months Basic Rent, plus sums paid as Additional Rent and any
deductibles related thereto. If such insurance cost is increased due to Tenant's
use of the Premises or the Complex, Tenant agrees to pay to Landlord the full
cost of such increase. Tenant shall have no interest in nor any right to the
proceeds of any insurance procured by Landlord for the Complex.

      In addition and notwithstanding anything to the contrary in this Paragraph
17, each party to this Lease hereby waives all rights of recovery against the
other party or its officer, employees, agents and representatives for loss or
damage to its property or the property of others under its control, arising from
any cause insured against under the fire and extended coverage (excluding,
however, any loss resulting from Hazardous Material contamination of the
Property) required to be maintained by the terms of this Lease Agreement to the
extent full reimbursement of the loss/claim is received by the insured party.
Each party required to carry property insurance hereunder shall cause the policy
evidencing such insurance to include a provision permitting such release of
liability ("waiver of subrogation endorsement") provided, however, that if the
insurance policy of either releasing party prohibits such waiver, then this
waiver shall not take effect until consent to such waiver is obtained; provided,
however, that if the insurance policy of either releasing party prohibits such
waiver, then this waiver shall not take effect until consent to such waiver is
obtained. If such waiver is so prohibited, the insured party affected shall
promptly notify the other party thereof. In the event the waivers are issued to
the parties and are not valid under current policies and/or subsequent insurance
policies, the non-complying party will provide, to the other party, 30 days
advance notification of the cancellation of the subrogation waiver, in which
case neither party will provide such subrogation waiver thereafter and this
Paragraph will be null and void. The foregoing waiver of subrogation shall not
include any loss resulting from Hazardous Material contamination of the Property
or any insurance coverage relating thereto.

      18. INDEMNIFICATION. Landlord shall not be liable to Tenant and Tenant
hereby waives all claims against Landlord for any injury to or death of any
person or damage to or destruction of property in or about the Premises or the
Complex by or from any cause whatsoever, including, without limitation, gas,
fire, oil, electricity or leakage of any character from the roof, walls,
basement or other portion of the Premises or the Complex but excluding, however,
the willful misconduct or negligence of Landlord, its agents, servants,
employees, invitees or contractors of which negligence Landlord has knowledge
and reasonable time to correct. Except as to injury to persons or damage to
property to the extent arising from the willful misconduct or the negligence of
Landlord, its agents, servants, employees, invitees, or contractors, Tenant
shall hold Landlord harmless from and defend Landlord against any and all
expenses, including reasonable

of any person or damage to or destruction of property occurring in, on or about
the Premises, or any part thereof, from any cause whatsoever, accruing and/or
occurring during the Term of this Lease.

      19. COMPLIANCE. Tenant, at its sole cost and expense, shall promptly
comply with all laws, statutes, ordinances and governmental rules, regulations
or requirements now or hereafter in effect; with the requirements of any board
of fire underwriters or other similar body now or hereafter constituted; and
with any direction or occupancy certificate issued pursuant to law by any public
officer; provided, however, that no such failure shall be deemed a breach of the
provisions if Tenant, immediately upon notification, commences to remedy or
rectify said failure. The judgment of any court of competent jurisdiction or the
admission of Tenant in any action against Tenant, whether Landlord be a party
thereto or not, that Tenant has violated any such law, statute, ordinance or
governmental rule, regulation, requirement, direction or provision, shall be
conclusive of that fact as between Landlord and Tenant. Tenant shall, at its
sole cost and expense, comply with any and all requirements pertaining to said
Premises, of any insurance organization or company, necessary for the
maintenance of reasonable fire and public liability insurance covering
requirements pertaining to said Premises.

      20. LIENS. Tenant shall keep the Premises free from any liens arising out
of any work performed, materials furnished or obligation incurred by Tenant. In
the event that Tenant shall not, within ten (10) days following notice of the
imposition of such lien, cause the same to be released of record, Landlord shall
have, in addition to all other remedies provided herein and by law, the right,
but no obligation, to cause the same to be released by such means as it shall
deem proper, including payment of the claim giving rise to such lien. All sums
paid by Landlord for such purpose, and all expenses incurred by it in connection
therewith, shall be payable to Landlord by Tenant on demand with interest at the
prime rate of interest as quote by the Bank of America.

      21. ASSIGNMENT AND SUBLETTING.

          A. Tenant shall not assign, transfer, or hypothecate the leasehold
estate under this Lease, or any interest therein, and shall not sublet the
Premises, or any part thereof, or any right or privilege appurtenant thereto, or
suffer any other person or entity to occupy or use the Premises, or any portion
thereof, without, in each case, the prior written consent of Landlord which
consent will not be unreasonably withheld. As a condition for granting this
consent to any assignment, transfer, or subletting, Landlord shall require that
(i) the sublease be a TRIPLE NET SUBLEASE and that the basic rent due under any
such sublease be no less than the then current market rent with annual increases
at the then prevailing market rent, (ii) that the sublease shall not provide for
subtenant to have an option to extend the term of the sublease or an option to
expand the sublet space, and (iii) Tenant pay Landlord monthly throughout the
term of any approved sublease, as Additional Rent (and therefore subject to the
terms of Paragraph 4.C ("Late Charge") and 24 ("Bankruptcy and Default"), all
rents and/or additional consideration due Tenant from its assignees,
transferees, or subtenants in excess of the Rent payable by Tenant to Landlord
hereunder for the assigned, transferred and/or subleased space ("Excess Rent").
Tenant shall, by thirty (30) days written notice, advise Landlord of its intent
to assign or transfer Tenant's interest in the Lease or sublet the Premises or
any portion thereof for any part of the Term hereof. Within thirty (30) days
after receipt of said written notice, Landlord may, in its sole discretion,
elect to terminate this Lease as to the portion of the Premises described in
Tenant's notice on the date specified in Tenant's notice by giving written
notice of such election to terminate. If no such notice to terminate is given to
Tenant within said thirty (30) day period, Tenant may proceed to locate an
acceptable sublessee, assignee, or other transferee for presentment to Landlord
for Landlord's approval, all in accordance with the terms, covenants, and
conditions of this Paragraph 21. If Tenant intends to sublet the entire Premises
and Landlord elects to terminate this Lease, this Lease shall be terminated on
the date specified in Tenant's notice. If, however, this Lease shall terminate
pursuant to the foregoing with respect to less than all the Premises, the Rent,
as defined and reserved hereinabove shall be adjusted on a pro rata basis to the
number of square feet retained by Tenant, and this Lease as so amended shall
continue in full force and effect. In the event Tenant is allowed to assign,
transfer or sublet the whole or any part of the Premises, with the prior written
consent of Landlord, no assignee, transferee or subtenant shall assign or
transfer this Lease, either in whole or in part, or sublet the whole or any part
of the Premises, without also having obtained the prior written consent of
Landlord. A consent of Landlord to one assignment, transfer, hypothecation,
subletting, occupation or use by any other person shall not release Tenant from
any of Tenant's obligations hereunder or be deemed to be a consent to any
subsequent similar or dissimilar assignment, transfer, hypothecation,
subletting, occupation or use by any other person. Any such assignment,
transfer,

hypothecation, subletting, occupation or use without such consent shall be void
and shall constitute a breach of this Lease by Tenant and shall, at the option
of Landlord exercised by written notice to Tenant, terminate this Lease. The
leasehold estate under this Lease shall not, nor shall any interest therein, be
assignable for any purpose by operation of law without the written consent of
Landlord. As a condition to its consent, Landlord shall require Tenant to pay
all expenses in connection with the sublease and/or assignment, and Landlord
shall require Tenant's subtenant, assignee or transferee (or other assignees or
transferees) to assume in writing all of the obligations under this Lease and
for Tenant to remain liable to Landlord under the Lease. Notwithstanding the
above, in no event shall Landlord consent to a sub-sublease.

      B. Notwithstanding the foregoing, Landlord and Tenant agree that it shall
not be unreasonable for Landlord to refuse to consent to a proposed assignment,
sublease or other transfer ("Proposed Transfer") if the Premises or any other
portion of the Property would become subject to additional or different
Government Requirements as a direct or indirect consequence of the Proposed
Transfer and/or the Proposed Transferee's use and occupancy of the Premises and
the Property. However, Landlord may, in its sole discretion, consent to such a
Proposed Transfer where Landlord is indemnified by Tenant and (i) Subtenant or
(ii) Assignee, in form and substance satisfactory to Landlord's counsel, by
Tenant and/or Proposed Transferee from and against any and all costs, expenses,
obligations and liability arising out of the Proposed Transfer and/or the
Proposed Transferee's use and occupancy of the Premises and the Property.

      C. Any and all sublease agreement(s) between Tenant and any and all
subtenant(s) (which agreements must be consented to by Landlord, pursuant to the
requirements of this Lease) shall contain the following language:

            "If Landlord and Tenant jointly and voluntarily elect, for any
      reason whatsoever, to terminate the Master Lease prior to the scheduled
      Master Lease termination date, then, if Landlord so elects, this Sublease
      (if then still in effect) shall terminate concurrently with the
      termination of the Master Lease. Subtenant expressly acknowledges and
      agrees that (1) the voluntary termination of the Master Lease by Landlord
      and Tenant and the resulting termination of this Sublease shall not give
      Subtenant any right or power to make any legal or equitable claim against
      Landlord, including without limitation any claim for interference with
      contract or interference with prospective economic advantage, and (2)
      Subtenant hereby waives any and all rights it may have under law or at
      equity against Landlord to challenge such an early termination of the
      Sublease, and unconditionally releases and relieves Landlord, and its
      officers, directors, employees and agents, from any and all claims,
      demands, and/or causes of action whatsoever (collectively, "Claims"),
      whether such matters are known or unknown, latent or apparent, suspected
      or unsuspected, foreseeable or unforeseeable, which Subtenant may have
      arising out of or in connection with any such early termination of this
      Sublease. Subtenant knowingly and intentionally waives any and all
      protection which is or may be given by Section 1542 of the California
      Civil Code which provides as follows: "A general release does not extend
      to claims which the creditor does not know or suspect to exist in his
      favor at the time of executing the release, which if known by him must
      have materially affected his settlement with debtor.

            The term of this Sublease is therefore subject to early termination.

      and agreement to this early termination provision, (b) Subtenant's
      acknowledgment that, in determining the net benefits to be derived by
      Subtenant under the terms of this Sublease, Subtenant has anticipated the
      potential for early termination, and (c) Subtenant's agreement to the
      general waiver and release of Claims above.

            22. SUBORDINATION AND MORTGAGES. In the event Landlord's title or
      leasehold interest is now or hereafter encumbered by a deed of trust, upon
      the interest of Landlord in the land and buildings in which the demised
      Premises are located, to secure a loan from a lender (hereinafter referred
      to as "Lender") to Landlord, Tenant shall, at the request of Landlord or
      Lender, execute in writing an agreement (in form reasonably acceptable to
      Tenant), subordinating its rights under this Lease to the lien of such
      deed of trust,

or, if so requested, agreeing that the lien of Lender's deed of trust shall be
or remain subject and subordinate to the rights of Tenant under this Lease.
Notwithstanding any such subordination, Tenant's possession under this Lease
shall not be disturbed if Tenant is not in default and so long as Tenant shall
pay all Rent and observe and perform all of the provisions set forth in this
Lease and any subordination agreement shall reflect the agreement of the Lender
to the same.

      23. ENTRY BY LANDLORD. Landlord reserves, and shall at all reasonable
times after at least twenty four (24) hours notice (except in emergencies) have
the right to enter the Premises to inspect them; to perform any services to be
provided by Landlord hereunder; to make repairs or provide any services to a
contiguous tenant(s) (if any); to submit the Premises to prospective purchasers,
mortgagers or tenants; to post notices of non-responsibility; and to alter,
improve or repair the Premises and any portion of the Complex, all without
abatement of Rent, and may erect scaffolding and other necessary structures in
or through the Premises where reasonably required by the character of the work
to be performed; provided, however that the business of Tenant shall be
interfered with to the least extent that is reasonably practical. Landlord shall
also have the right at any time to change the arrangement or location of
entrances or passageways, doors and doorways, and corridors, elevators, stairs,
toilets or other public parts of the Complex and to change the name, number or
designation by which the Complex is commonly known, and none of the foregoing
shall be deemed an actual or constructive eviction of Tenant, or shall entitle
Tenant to any reduction of Rent hereunder. Any entry to the Premises by Landlord
for the purposes provided for herein shall not under any circumstances be
construed or deemed to be a forcible or unlawful entry into or a detainer of the
Premises or an eviction, actual or constructive, of Tenant from the Premises or
any portion thereof.

      24. BANKRUPTCY AND DEFAULT. The commencement of a bankruptcy action or
liquidation action or reorganization action or insolvency action or an
assignment of or by Tenant for the benefit of creditors, or any similar action
undertaken by Tenant, or the insolvency of Tenant, shall, at Landlord's option,
constitute a breach of this Lease by Tenant. If the trustee or receiver
appointed to serve during a bankruptcy, liquidation, reorganization, insolvency
or similar action elects to reject Tenant's unexpired Lease, the trustee or
receiver shall notify Landlord in writing of its election within thirty (30 days
after an order for relief in a liquidation action or within thirty (30) days
after the commencement of any action.

      Within thirty (30) days after the court approval of the assumption of this
Lease, the trustee or receiver shall cure (or provide adequate assurance to the
reasonable satisfaction of Landlord that the trustee or receiver shall cure) any
and all previous defaults under the unexpired Lease and shall compensate
Landlord for all actual pecuniary loss and shall provide adequate assurance of
future performance under said Lease to the reasonable satisfaction of Landlord.
Adequate assurance of future performance, as used herein, includes, but shall
not be limited to: (i) assurance of source and payment of Rent, and other
consideration due under this Lease; (ii) assurance that the assumption or
assignment of this Lease will not breach substantially any provision, such as
radius, location, use, or exclusivity provision, in any agreement relating to
the above described Premises.

      Nothing contained in this section shall affect the existing right of
Landlord to refuse to accept an assignment upon commencement of or in connection
with a bankruptcy, liquidation, reorganization or insolvency action or an
assignment of Tenant for the benefit of creditors or other similar act. Nothing
contained in this Lease shall be construed as giving or granting or creating an
equity in the demised Premises to Tenant. In no event shall the leasehold estate
under this Lease, or any interest therein, be assigned by voluntary or
involuntary bankruptcy proceeding without the prior written consent of Landlord.
In no event shall this Lease or any rights or privileges hereunder be an asset
of Tenant under any bankruptcy, insolvency or reorganization proceedings.

      The failure to perform or honor any covenant, condition or representation
made under this Lease shall constitute a default under this Lease by Tenant upon
expiration of the appropriate grace period hereinafter provided. Tenant shall
have a period of five (5) days from the date of written notice from Landlord
within which to cure any default in the payment of Rent or adjustment thereto.
Tenant shall have a period of thirty (30) days from the date of written notice
from Landlord within which to cure any other non-monetary default under this
Lease; provided, however, that with respect to non-monetary defaults not
involving Tenant's failure to pay Basic Rent or Additional Rent, Tenant shall
not be in default if (i) more than thirty (30) days is required to cure such
non-monetary default and (ii) Tenant commences cure of such default as soon as
reasonably practicable after receiving written notice of such default from
Landlord and thereafter continuously and with due diligence prosecutes such cure
to completion. Upon an uncured default

of this Lease by Tenant, Landlord shall have the following rights and remedies
in addition to any other rights or remedies available to Landlord at law or in
equity:

      (a) The rights and remedies provided for by California Civil Code Section
1951.2 including but not limited to, recovery of the worth at the time of award
of the amount by which the unpaid Rent for the balance of the Term after the
time of award exceeds the amount of rental loss for the same period that Tenant
proves could be reasonably avoided, as computed pursuant to subsection (b) of
said Section 1951.2. Any proof by Tenant under subparagraphs (2) and (3) of
Section 1951.2 of the California Civil Code of the amount of rental loss that
could be reasonably avoided shall be made in the following manner: Landlord and
Tenant shall each select a licensed real estate broker in the business of
renting property of the same type and use as the Premises and in the same
geographic vicinity. Such two real estate brokers shall select a third licensed
real estate broker, and the three licensed real estate brokers so selected shall
determine the amount of the Rent loss that could be reasonably avoided from the
balance of the Term of this Lease after the time of award. The decision of the
majority of said licensed real estate brokers shall be final and binding upon
the parties hereto.

      (b) The rights and remedies provided by California Civil Code Section
which allows Landlord to continue the Lease in effect and to enforce all of its
rights and remedies under this Lease, including the right to recover Rent as it
becomes due, for so long as Landlord does not terminate Tenant's right to
possession; acts of maintenance or preservation, efforts to relet the Premises,
or the appointment of a receiver upon Landlord's initiative to protect its
interest under this Lease shall not constitute a termination of Tenant's right
to possession.

      (c) The right to recover that portion of any leasing commission paid by
Lessor in connection with this Lease applicable to the unexpired Term of this
Lease.

      (d) The right to terminate this Lease by giving notice to Tenant in
accordance with applicable law.

      (e) To the extent permitted by law, the right and power to enter the
Premises and remove therefrom all persons and property, to store such property
in a public warehouse or elsewhere at the cost of and for the account of Tenant,
and to sell such property and apply such proceeds therefrom pursuant to
applicable California law. Landlord may from time to time sublet the Premises or
any part thereof for such term or terms (which may extend beyond the Term of
this Lease) and at such Rent and such other terms as Landlord in its reasonable
sole discretion may deem advisable, with the right to make alterations and
repairs to the Premises. Upon each subletting, (i) Tenant shall be immediately
liable to pay Landlord, in addition to indebtedness other than Rent due
hereunder, the reasonable cost of such subletting, including, but not limited
to, reasonable attorneys' fees, and any real estate commissions actually paid,
and the cost of such reasonable alterations and repairs incurred by Landlord and
the amount, if any, by which the Rent hereunder for the period of such
subletting (to the extent such period does not exceed the Term hereof) exceeds
the amount to be paid as Rent for the Premises for such period or (ii) at the
option of Landlord, rents received from such subletting shall be applied first
to payment of indebtedness other than Rent due hereunder from Tenant to
Landlord; second, to the payment of any costs of such subletting and of such
alterations and repairs; third, to payment of Rent due and unpaid hereunder; and
the residue, if any, shall be held by Landlord and applied in payment of future
Rent as the same becomes due hereunder. If Tenant has been credited with any
Rent to be received by such subletting under option (i) and such Rent shall not
be promptly paid to Landlord by the subtenant(s), or if such rentals received
from such subletting under option (ii) during any month be less than that to be
paid during the month by Tenant hereunder, Tenant shall pay any such deficiency
to Landlord. Such deficiency shall be calculated and paid monthly. No taking
possession of the Premises by Landlord shall be construed as an election on its
part to terminate this Lease unless a written notice of such intention be given
to Tenant. Notwithstanding any such subletting without termination, Landlord may
at any time hereafter elect to terminate this Lease for such previous breach.

      (f) The right to have a receiver appointed for Tenant upon application by
Landlord, to take possession of the Premises and to apply any rental collected
from the Premises and to exercise all other rights and remedies granted to
Landlord pursuant to subparagraph (e) above.

      25. ABANDONMENT. Tenant shall not vacate or abandon the Premises at any
time during the Term of this Lease and if Tenant shall abandon, vacate or
surrender said Premises, or be dispossessed by the process of law, or otherwise,
any personal property belonging to Tenant and left on the Premises shall be.

deemed to be abandoned, at the option of Landlord, except such property as may
be mortgaged to Landlord. Notwithstanding the above, Tenant shall not be in
default under the Lease if it leaves all or any part of Premises vacant so long
as (i) Tenant is performing all of its other obligations under the Lease
including the obligation to pay Rent (ii) Tenant provides on-site security
during normal business hours for those parts of the Premises left vacant, (iii)
such vacancy does not materially and adversely affect the validity or coverage
of any policy of insurance carried by Landlord with respect to the Premises, and
(iv) the utilities and heating and ventilation systems are operated and
maintained to the extent necessary to prevent damage to the Premises or its
systems.

      26. DESTRUCTION. In the event the Premises are destroyed in whole or in
part from any cause, except for routine maintenance and repairs and incidental
damage and destruction caused from vandalism and accidents for which Tenant is
responsible under Paragraph 11, Landlord may, at its option:

      (a)   Rebuild or restore the Premises to their condition prior to the
damage or destruction, or

      (b)   Terminate this Lease (providing that the Premises is damaged to the
extent of 33 1/3% or more of the replacement cost, exclusive of footings,
foundations and floor slabs).

      If Landlord does not give Tenant notice in writing within thirty (30) days
from the destruction of the Premises of its election to either rebuild and
restore them, or to terminate this Lease, Landlord shall be deemed to have
elected to rebuild or restore them, in which event Landlord agrees, at its
expense except for any deductible, which is the responsibility of the Tenant,
promptly to rebuild or restore the Premises to their condition prior to the
damage or destruction. Tenant shall be entitled to a reduction in Rent from the
date of such damage or destruction, provided Tenant is not using any portion of
such damaged area, while such repair is being made in the proportion that the
area of the Premises rendered untenantable by such damage bears to the total
area of the Premises. If Landlord initially estimates that the rebuilding or
restoration will exceed 180 days (or 60 days during the last twelve months of
the Lease Term) or if Landlord does not complete the rebuilding or restoration
within one hundred eighty (180) days (or 60 days during the last twelve months
of the Lease Term) following the date of destruction (such period of time to be
extended for delays caused by the fault or neglect of Tenant or because of Acts
of God, acts of public agencies, labor disputes, strikes, fires, freight
embargos, rainy or stormy weather, inability to obtain materials, supplies or
fuels, acts of contractors or subcontractors, or delay of the contractors or
subcontractors due to such causes or other contingencies beyond the control of
Landlord), then Tenant shall have the right to terminate this Lease by giving
written notice to Landlord within five days following the date Tenant receives
Landlord's written notice stating that the restoration will exceed 180 days (or
60 days during the last twelve months of the Lease Term). Regardless of whether
Landlord and/or Tenant elects to terminate the Lease early as provided herein,
Tenant shall remain liable for the insurance deductible as it relates to the
Leased Premises. Notwithstanding anything herein to the contrary, Landlord's
obligation to rebuild or restore shall be limited to the building and interior
improvements constructed by Landlord as they existed as of the Commencement Date
of the Lease and shall not include restoration of Tenant's trade fixtures,
equipment, merchandise, or any improvements, alterations or additions made by
Tenant to the Premises, which Tenant shall forthwith replace or fully repair at
Tenant's sole cost and expense provided this Lease is not canceled according to
the provisions above.

      Unless this Lease is terminated pursuant to the foregoing provisions, this
Lease shall remain in full force and effect. Tenant hereby expressly waives the
provision of Section 1932, Subdivision 2, in Section 1933, Subdivision 4 of the
California Civil Code.

      In any event that the building in which the Premises are situated is
damaged or destroyed to the extent of not less than 33 1/3% of the replacement
cost thereof, Landlord may elect to terminate this Lease, whether the Premises
be injured or not. Notwithstanding anything to the contrary herein, Landlord may
terminate this lease in the event of an uninsured event or if insurance proceeds
are insufficient to cover one hundred percent of the rebuilding costs net of the
deductible.

      27. EMINENT DOMAIN. If all or any part of the Premises shall be taken by
any public or quasi-public authority under the power of eminent domain or
conveyance in lieu thereof, this Lease shall terminate as to any portion of the
Premises so taken or conveyed on the date when title vests in the condemnor, and
Landlord shall be entitled to any and all payment, income, rent, award, or any
interest therein whatsoever which may be paid or made in connection with such
taking or conveyance, and Tenant shall have no claim against Landlord or
otherwise for the value of any unexpired Term of this Lease. Notwithstanding the

foregoing sentence, any compensation specifically awarded Tenant for loss of
business, Tenant's personal property, moving costs or loss of goodwill, shall be
and remain the property of Tenant.

      If (i) any action or proceeding is commenced for such taking of the
Premises or any part thereof, or if Landlord is advised in writing by any entity
or body having the right or power of condemnation of its intention to condemn
the Premises or any part thereof, or (ii) any of the foregoing events occur with
respect to the taking of any space in the Complex not leased hereby, or if any
such spaces so taken or conveyed in lieu of such taking and Landlord shall
decide to discontinue the use and operation of the Complex, or decide to
demolish, alter or rebuild the Complex, then in any such events Landlord shall
have the right to terminate this Lease by giving Tenant written notice thereof
within sixty (60) days of the date of receipt of said written advice, or
commencement of said action or proceeding, or taking conveyance, which
termination shall take place as of the first to occur of the last day of the
calendar month next following the month in which such notice is given or the
date on which title to the Premises shall vest in the condemnor.

      In the event of such a partial taking or conveyance of the Premises, if
the portion of the Premises taken or conveyed is so substantial that the Tenant
can no longer reasonably conduct its business, Tenant shall have the privilege
of terminating this Lease within sixty (60) days from the date of such taking or
conveyance, upon written notice to the Landlord of its intention so to do, and
upon giving of such notice this Lease shall terminate on the last day of the
calendar month next following the month in which such notice is given, upon
payment by Tenant of the Rent from the date of such taking or conveyance to the
date of termination.

      If a portion of the Premises be taken by condemnation or conveyance in
lieu thereof and neither Landlord nor Tenant shall terminate this Lease as
provided herein, this Lease shall continue in full force and effect as to the
part of the Premises not so taken or conveyed, and the Rent herein shall be
apportioned as of the date of such taking or conveyance so that thereafter the
Rent to be paid by Tenant shall be in the ratio that the area of the portion of
the Premises not so taken or conveyed bears to the total area of the Premises
prior to such taking.

      28. SALE OR CONVEYANCE BY LANDLORD. In the event of a sale or conveyance
of the Premises or any interest therein, by any owner of the reversion then
constituting Landlord, the transferor shall thereby be released from any further
liability upon any of the terms, covenants or conditions (express or implied)
herein contained in favor of Tenant, and in such event, insofar as such transfer
is concerned, Tenant agrees to look solely to the responsibility of the
successor in interest of such transferor in and to the Complex and this Lease.
This Lease shall not be affected by any such sale or conveyance, and Tenant
agrees to attorn to the successor in interest of such transferor.

      29. ATTORNMENT TO LENDER OR THIRD PARTY. In the event the interest of
Landlord in the land and buildings in which the Leased Premises are located
(whether such interest of Landlord is a fee title interest or a leasehold
interest) is encumbered by deed of trust, and such interest is acquired by the
lender or any third party through judicial foreclosure or by exercise of a power
of sale at private trustee's foreclosure sale, Tenant hereby agrees to attorn to
the purchaser at any such judicial foreclosure or foreclosure sale and to
recognize such purchaser as the Landlord under this Lease. In the event the lien
of the deed of trust securing the loan from a Lender to Landlord is prior and
paramount to the Lease, this Lease shall nonetheless continue in full force and
effect for the remainder of the unexpired Term hereof, at the same rental herein
reserved and upon all the other terms, conditions and covenants herein
contained.

      30. HOLDING OVER. Any holding over by Tenant after expiration or other
termination of the Term of this Lease with the written consent of Landlord
delivered to Tenant shall not constitute a renewal or extension of the Lease or
give Tenant any rights in or to the Leased Premises except as expressly provided
in this Lease. Any holding over after the expiration or other termination of the

      31. CERTIFICATE OF ESTOPPEL. Tenant shall within ten (10) days of receipt
of prior written notice from Landlord execute, acknowledge and deliver to
Landlord a statement in writing (i) certifying that this Lease is unmodified and
in full force and effect (or, if modified, stating the nature of such
modification and certifying that this Lease, as so modified, is in full force
and effect) and the date to which the Rent and other charges are paid in
advance, if any, and (ii) acknowledging that there are not, to Tenant's
knowledge, any uncured defaults on the part of Landlord hereunder, or specifying
such defaults, if any, are claimed. Any such statement may be conclusively
relied upon by any prospective purchaser or encumbrancer of the Premises.
Tenant's failure to deliver such statement within such time shall be conclusive
upon Tenant that this Lease is in full force and effect, without modification
except as may be represented by Landlord; that there are no uncured defaults in
Landlord's performance, and that not more than one month's Rent has been paid in
advance.

      32.CONSTRUCTION CHANGES. It is understood that the description of the
Premises and the location of ductwork, plumbing and other facilities therein are
subject to such minor changes as Landlord or Landlord's architect determines to
be desirable in the course of construction of the Premises, and no such changes
or any changes in plans for any other portions of the Complex shall affect this
Lease or entitle Tenant to any reduction of Rent hereunder or result in any
liability of Landlord to Tenant. Landlord does not guarantee the accuracy of any
drawings supplied to Tenant and verification of the accuracy of such drawings
rests with Tenant.

      33. RIGHT OF LANDLORD TO PERFORM. All terms, covenants and conditions of
this Lease to be performed or observed by Tenant shall be performed or observed
by Tenant at Tenant's sole cost and expense and without any reduction of rent.
If Tenant shall fail to pay any sum of money, or other Rent, required to be paid
by it hereunder and such failure shall continue for five (5) days after written
notice thereof by Landlord or shall fail to perform any other term of covenant
hereunder on its part to be performed, and such failure shall continue for
thirty (30) days after written notice thereof by Landlord (or such longer grace
period as shall be provided under Paragraph 24), Landlord, without waiving or
releasing Tenant from any obligation of Tenant hereunder, may, but shall not be
obliged to, make any such payment or perform any such other term or covenant on
Tenant's part to be performed. All sums so paid by Landlord and all necessary
costs of such performance by Landlord together with interest thereon at the rate
of the prime rate of interest per annum as quoted by the Bank of America from
the date of such payment or performance by Landlord, shall be paid (and Tenant
covenants to make such payment) to Landlord within five (5) business days after
demand by Landlord, and Landlord shall have (in addition to any other right or
remedy of Landlord) the same rights and remedies in the event of nonpayment by
Tenant as in the case of failure by Tenant in the payment of Rent hereunder.

      34. ATTORNEYS' FEES.

      A. In the event that Landlord should bring suit for the possession of the
Premises, for the recovery of any sum due under this Lease, or because of the
breach of any provision of this Lease, or for any other relief against Tenant
hereunder, then all costs and expenses, including reasonable attorneys' fees,
incurred by Landlord therein shall be paid by Tenant, which obligation on the
part of Tenant shall be deemed to have accrued on the date of the commencement
of such action and shall be enforceable whether or not the action is prosecuted
to judgment.

      B. Should Landlord be named as a defendant in any suit brought against
Tenant in connection with or arising out of Tenant's occupancy hereunder, Tenant
shall pay to Landlord its costs and expenses incurred in such suit, including
reasonable attorney's fees.

      35. WAIVER. The waiver by either party of the other party's failure to
perform or observe any term, covenant or condition herein contained to be
performed or observed by such waiving party shall not be deemed to be a waiver
of such term, covenant or condition or of any subsequent failure of the party
failing to perform or observe the same or any other such term, covenant or
condition therein contained, and no custom or practice which may develop between
the parties hereto during the Term hereof shall be deemed a waiver of, or in any
way affect, the right of either party to insist upon performance and observance
by the other party in strict accordance with the terms hereof.

      36. NOTICES. All notices, demands, requests, advices or designations which
may be or are required to be given by either party to the other hereunder shall

Property during the term of the Lease of which Tenant becomes aware, and further

which Tenant becomes aware. If Tenant's Hazardous Materials Activities involve
Hazardous Materials other than normal use of customary household and office

Hazardous Materials Activities. Tenant, at its expense, shall submit to Landlord
a report from such environmental consultant which discusses the environmental

its expense, shall promptly undertake and complete any and all steps necessary,
and in full compliance with applicable Environmental Laws, to fully correct any
and all problems or deficiencies identified by the environmental consultant, and
promptly provide Landlord with documentation of all such corrections.

      C.    Prior to termination or expiration of the Lease, Tenant, at its
expense, shall (i) properly remove from the Property all Hazardous Materials

Environmental Laws or other laws, may enter upon the Property and conduct
inspection, sampling and analysis, including but not limited to obtaining and
analyzing samples of soil and groundwater, for the purpose of determining the
nature and extent of such contamination. Tenant shall promptly reimburse
Landlord for the costs of such an investigation, including but not limited to
reasonable attorneys' fees Landlord incurs with respect to such investigation,
that discloses Hazardous Materials contamination for which Tenant is liable
under this Lease. Except as may be required of Tenant by applicable
Environmental Laws, Tenant shall not perform any sampling, testing, or drilling
to identify the presence of any Hazardous Materials at the Property, without
Landlord's prior written consent which may be withheld in Landlord's discretion.
Tenant shall promptly provide Landlord with copies of any claims, notices, work
plans, data and reports prepared, received or submitted in connection with any
sampling, testing or drilling performed pursuant to the preceding sentence.

      E.    Tenant shall indemnify, defend (with legal counsel acceptable to
Landlord, whose consent shall not unreasonably be withheld) and hold harmless
Landlord, its employees, assigns, successors, successors-in-interest, agents and
representatives from and against any and all claims (including but not limited

liabilities, obligations, losses, causes of action, demands, governmental
proceedings or directives, fines, penalties, expenses, costs (including but not
limited to reasonable attorneys', consultants' and other experts' fees and
costs), and damages, which arise from or relate to: (i) Tenant's Hazardous
Materials Activities; (ii) any Hazardous Materials contamination caused by
Tenant prior to the Commencement Date of the Lease; or (iii) the breach of any
obligation of Tenant under this Paragraph 44 (collectively, "Tenant's
Environmental Indemnification"). Tenant's Environmental Indemnification shall
include but is not limited to the obligation to promptly and fully reimburse
Landlord for losses in or reductions to rental income, and diminution in fair
market value of the Property. Tenant's Environmental Indemnification shall
further include but is not limited to the obligation to diligently and properly
implement to completion, at Tenant's expense, any and all environmental
investigation, removal, remediation, monitoring, reporting, closure activities,
or other environmental response action (collectively, "Response Actions").
Tenant shall promptly provide Landlord with copies of any claims, notices, work
plans, data and reports prepared, received or submitted in connection with any
