this Sublease, Rent shall be payable in lawful money without notice or demand,
and without offset, counterclaim, or setoff in monthly installments, in advance,
on the first day of each and every month during the Sublease Term. All of said
Rent is to be paid to Sublandlord at its office at the address set forth in

as Sublandlord may designate by notice to Subtenant. Any additional rent payable
on account of items which are not payable monthly by Sublandlord to Landlord
under the Phase A Lease is to be paid directly to Sublandlord as and when such
items are payable by Sublandlord to Landlord under the Phase A Lease unless a
different time for payment is elsewhere stated herein. Sublandlord shall request
that copies of all notices sent by Landlord pursuant to the Phase A Lease also

               4. Security Deposit. Concurrently with the execution of this
Sublease, Subtenant shall deposit with Sublandlord the sum of Eighty Four
Thousand and no/100 Dollars ($84,000.00) ("Deposit"), which shall be held by
Sublandlord as security for the full and faithful performance by Subtenant of
its covenants and obligations under this Sublease. The Deposit is not an advance
Rent deposit, an advance payment of any other kind, or a measure of
Sublandlord's damage in case of Subtenant's default. If Subtenant defaults in
the full and timely performance of any or all of Subtenant's covenants and
obligations set forth in this Sublease, then Sublandlord may, from time to time,
without waiving any other remedy available to Sublandlord, use the Deposit, or
any portion of it, to the extent necessary to cure or remedy the default or to
compensate Sublandlord for all or a part of the damages sustained by Sublandlord
resulting from Subtenant's default. Subtenant shall immediately pay to
Sublandlord within five (5) business days following demand, the amount so
applied in order to restore the Deposit to its original amount, and Subtenant's
failure to immediately do so shall constitute a default under this Sublease. If
Subtenant is not in default with respect to the covenants and obligations set
forth in this Sublease at the expiration or earlier termination of this
Sublease, Sublandlord shall return the Deposit to Subtenant after the expiration
or earlier termination of this Sublease. Sublandlord's obligations with respect
to the Deposit are those of a debtor and not a trustee. Sublandlord shall not be
required to maintain the Deposit separate and apart from Sublandlord's general
and other funds and Sublandlord may commingle the Deposit with any of
Sublandlord's general or other funds. Subtenant shall not at any time be
entitled to interest on the Deposit.

               5. Additional Security Deposit; Letter of Credit.

               (a) Delivery of Letter of Credit. In addition to delivering the
Deposit, Subtenant shall also, on execution of this Sublease, deliver to
Sublandlord and cause to be in effect during the entire Sublease Term an
unconditional, irrevocable letter of credit ("LOC") in the amount of Three
Hundred Fifty Two Thousand Five Hundred and no/100 Dollars ($352,500.00), as
such LOC may be increased as provided in this Sublease (the "LOC AMOUNT") for a
term extending not less than thirty (30) days beyond the expiration date of this
Sublease, which LOC shall be held by Sublandlord as security for the full and
faithful performance by Subtenant of its covenants and obligations under this
Sublease. The LOC shall be in a form acceptable to Sublandlord, shall permit
partial draws and shall be issued by a bank selected by Subtenant and acceptable
to Sublandlord. The issuer of the LOC shall be a commercial bank that accepts
deposits, maintains accounts, has a local office in San Diego County that will
negotiate a letter of credit, and the deposits of which are insured by the
Federal Deposit Insurance Corporation. Such bank shall have a shareholders
equity of at least Five Hundred Million Dollars ($500,000,000.00). Subtenant
shall pay all expenses, points, or fees (including any transfer fees) incurred
by Subtenant in obtaining the LOC. The LOC shall not be mortgaged, assigned or
encumbered in any manner whatsoever by Subtenant without the prior written
consent of Sublandlord, which consent may be withheld in the exercise of
Sublandlord's sole and absolute discretion.

               (b) Replacement of Letter of Credit. Subtenant may, from time to
time, replace any existing LOC with a new LOC if the new LOC (i) becomes
effective at least thirty (30) days before expiration of the LOC that it
replaces; (ii) is in the required LOC amount; (iii) is issued by a bank
acceptable to Sublandlord; and (iv) otherwise complies with the requirements of
this Paragraph 5.

               (c) Sublandlord's Right to Draw on Letter of Credit. Sublandlord
shall hold the LOC as security for the performance of Subtenant's obligations
under this Sublease. If, after any required notice and failure to cure within
any applicable period provided in this Sublease, Subtenant defaults on any
provision of this Sublease, Sublandlord may, without prejudice to any other
remedy it has, only draw on that portion of the LOC necessary to (i) pay Rent or
other sum in default; (ii) pay or reimburse Sublandlord for any amount that
Sublandlord may spend or become obligated to spend in exercising Sublandlord's
rights under Paragraph 30 (Right of Landlord to Perform Tenant's Covenant) of
the Phase A Lease; and/or (iii) compensate Sublandlord for any expense, loss, or
damage that Sublandlord may suffer because of Subtenant's default. If Subtenant
fails to renew or replace the LOC at least thirty (30) days before its
expiration, Sublandlord may, without prejudice to any other remedy it has, draw
on the entire amount of the LOC, provided that if Sublandlord so draws on the
LOC, so long as Subtenant is not otherwise in default, Sublandlord shall deliver
the amount so drawn to Subtenant upon Subtenant's delivery to Sublandlord of a
new LOC in the amount then required, provided that Subtenant makes such delivery
within ten (10) days of Sublandlord's draw.

               (d) LOC Security Deposit. Any amount of the LOC that is drawn on
by Sublandlord but not applied by Sublandlord shall be held by Sublandlord as a
security deposit (the "LOC SECURITY DEPOSIT") in accordance with Paragraph 4 of
this Sublease and returned to Subtenant within five (5) business days of
Subtenant's restoration of the LOC to the full amount required under this
Sublease.

               (e) Restoration of Letter of Credit and LOC Security Deposit. If
Sublandlord draws on any portion of the LOC and applies all or any portion of
such draw, Subtenant shall, within five (5) business days after demand by
Sublandlord, either (i) deposit cash with Sublandlord in an amount that, when
added to the amount remaining under the LOC and the amount of any LOC Security
Deposit, shall equal the LOC Amount then required under this Paragraph 5 or (ii)
reinstate the LOC to the full LOC Amount. Any portion of the LOC drawn by
Sublandlord but not applied shall be returned to Subtenant upon Subtenant's
restoration of the LOC Amount as required hereby.

               (f) Required LOC Amount. Notwithstanding the forgoing,
Subtenant's required LOC Amount shall be increased when Subtenant exercises any
of its rights to expand its Sublease Premises, as allowed in Paragraphs 7 and 8,
by an amount that is equal to six (6) months of the initial Base Rent for any
expansion space (as such amount may be reduced in accordance with the procedures
set forth in subparagraph (g) below). Said increase in LOC shall be completed
and an amended LOC shall be delivered to Sublandlord upon execution of any
amendment for such expansion space.

               (g) Reduction of LOC Amount.

               to the Reduction Limit, if Subtenant has so satisfied the
               applicable Financial Milestones, the LOC shall be reduced
               effective as of the Release Date by the Reduction Increment,
               unless Subtenant has so satisfied the applicable Secondary
               Milestones, in which event the LOC shall be reduced by the
               Secondary Reduction Increment. Promptly following any such
               Release Date, Sublandlord shall provide written notice to
               Subtenant of any such permitted reduction in the amount of the
               LOC and then, from and after Subtenant's receipt of such
               Sublandlord notice, Subtenant shall be authorized to deliver a
               substitute or amended LOC to

                                       7

               Paragraph 5 and in an amount equal to the LOC as reduced by such

               may be, and Sublandlord shall exchange the prior LOC for the
               substitute LOC in cooperation with the bank.

does not exercise the FR to Sublease the Designated Space portion of the Phase
B-2 Premises in accordance with the provisions of Paragraphs 7 and 8 and
Sublandlord subleases or Landlord leases the Designated Space to a Prospective
Tenant, this FR to Sublease the Designated Space portion of the Phase B-2
Premises shall expire and shall be null and void. This FR to Sublease Phase B-2
Premises shall be personal to Subtenant and may not be sublet or assigned to any
third party. The term of any sublease for the Phase B-2 Space shall expire
pursuant to the terms of the Phase B Master Lease, which scheduled term
expiration date is April 30, 2010.

                      Upon execution of an amendment for said expansion space,
Subtenant shall deposit with Sublandlord an additional security deposit in an
amount equal to the last month's rent for the Phase B-2 Premises, plus an
increase in the LOC amount by an amount equal to 6 months of base rent with
respect thereto (as such amount may be decreased in accordance with the
provisions of Paragraph 5(g)).

                      9. Right of First Offer to Sublease the Phase A-2 Premises
and/or the Phase B-2 Premises.

               a. In addition to the first right to sublease described in

written negotiations with a third party to sublease less than the entire
building (in full-floor increments) of either the Phase A-2 Premises or Phase
B-2 Premises on terms which Sublandlord is prepared to accept.

Tenant, respectively, under the Phase A Lease) constitute the terms of this
Sublease except to the extent that they are inapplicable to, inconsistent with,
or modified by, the terms of this Sublease. In the event of any inconsistencies
between the terms and provisions of the Phase A Lease and the terms and
provisions of this Sublease, the terms and provisions of this Sublease shall
govern. Subtenant acknowledges that it has reviewed the Phase A Lease and is

                                       11
<PAGE>   12

                      (i) In all provisions of the Phase A Lease (under the
               terms thereof and without regard to modifications thereof for
               purposes of incorporation into this Sublease) requiring the
               approval or consent of Landlord, Subtenant shall be required to
               obtain the approval or consent of Landlord and Sublandlord.

                      (ii) In all provisions of the Phase A Lease requiring
               Tenant to submit, exhibit to, supply or provide Landlord with
               evidence, certificates, or any other matter or thing, Subtenant
               shall be required to submit, exhibit to, supply or provide, as
               the case may be, the same to Landlord and Sublandlord.

                      (iii) Sublandlord shall have no obligation to restore or
               rebuild any portion of the Sublease Premises after any
               destruction or taking by eminent domain.

               (c) The following provisions of the Phase A Lease are
        specifically excluded: all of the Basic Lease Information, Paragraph 1,
        Paragraph 2, Paragraph 3, the requirement for two months prepaid rent in

        last two sentences of Paragraph 25, Paragraph 32, Paragraph 38.A.,
        Paragraph 38.B., Paragraph 38.C., Paragraph 38.D., Paragraph 38.E.,
        Exhibit B, Exhibit C (Tenant Improvement Agreement). Furthermore,
        Paragraphs 1 through 5 and 12 and Exhibits A and B of the First
        Amendment to Lease are hereby deleted.

11. Subtenant's Obligations. Subtenant covenants and agrees that all obligations
of Sublandlord under the Phase A Lease shall be done or performed by Subtenant
with respect to the Sublease Premises, except as otherwise provided by this
Sublease, and Subtenant's obligations shall run to Sublandlord and Landlord as
Sublandlord may determine to be appropriate or be required by the respective
interests of Sublandlord and Landlord. Subtenant agrees to indemnify
Sublandlord, and hold it harmless, from and against any and all claims, damages,
losses, expenses and liabilities (including reasonable attorneys' fees) incurred
as a result of the non-performance, non-observance or non-payment of any of
Sublandlord's obligations under the Phase A Lease applicable to the Sublease
Premises which, as a result of this Sublease, became an obligation of Subtenant.
Subtenant shall not do, nor permit to be done, any act or thing which is, or
with notice or the passage of time would be, a default under this Sublease or
the Phase A Lease (to the extent applicable to the Sublease Premises).
Sublandlord agrees to indemnify Subtenant, and hold it harmless, from and
against any and all claims, damages, losses, expenses and liabilities (including
reasonable attorneys' fees) incurred as a result of the non-performance,
non-observance or non-payment of any of Sublandlord's obligations under the
Phase A Lease

12. Sublandlord's Obligations. Sublandlord agrees that Subtenant shall be
entitled to receive all services and repairs to be provided by Landlord to
Sublandlord under the Phase A Lease. Subtenant shall look solely to Landlord for
all such services and shall not, under any circumstances, seek nor require
Sublandlord to perform any of such services, nor shall Subtenant make any claim
upon Sublandlord for any damages which may arise by reason of Landlord's default
under the Phase A Lease. Any condition resulting from a default by Landlord
shall not constitute as between Sublandlord and Subtenant an eviction, actual or
constructive, of Subtenant

                                       12
<PAGE>   13

and no such default shall excuse Subtenant from the performance or observance of
any of its obligations to be performed or observed under this Sublease, or,
except as otherwise provided in this Sublease, entitle Subtenant to receive any
reduction in or abatement of the Rent provided for in this Sublease. In
furtherance of the foregoing, and subject to Paragraph 14 hereof, Subtenant does
hereby waive any cause of action and any right to bring any action against
Sublandlord by reason of any act or omission of Landlord under the Phase A
Lease. Sublandlord covenants and agrees with Subtenant that Sublandlord will pay
all fixed rent and additional rent payable by Sublandlord pursuant to the Phase
A Lease. In the event of a breach by Landlord of any term of the Phase A Lease,
then Sublandlord's sole obligation in regard to its obligation under this
Sublease shall be to diligently pursue the correction or cure by Landlord of
Landlord's breach. Such efforts shall include, without limitation, upon
Subtenant's request, (a) immediately notifying Landlord of its non-performance
under the Phase A Lease and demanding that Landlord perform its obligations
under the Phase A Lease and/or (b) assigning Sublandlord's rights under the
Phase A Lease to Subtenant to the extent necessary to permit Subtenant to
institute legal proceedings against Landlord to obtain the performance of
Landlord's obligations under the Phase A Lease; provided, however, that if
Subtenant commences a lawsuit or other action, Subtenant shall pay all costs and
expenses incurred in connection therewith, and Subtenant shall indemnify
Sublandlord against, and hold Sublandlord harmless from, all costs and expenses
incurred by Sublandlord in connection therewith.

13. Default by Subtenant. In the event Subtenant shall be in default of any
covenant of, or shall fail to honor any obligation under, this Sublease,
Sublandlord shall have available to it against Subtenant all of the remedies
available (a) to Landlord under the Phase A Lease in the event of a similar
default on the part of Sublandlord thereunder or (b) at law.

14. Quiet Enjoyment. So long as Subtenant pays all of the Rent due hereunder and
performs all of Subtenant's other obligations hereunder, Sublandlord shall do
nothing to affect Subtenant's right to peaceably and quietly have, hold and
enjoy the Sublease Premises, and all of the rights, entitlements, and options
granted to Subtenant hereunder. In the event, however, that Sublandlord defaults
in the performance or observance of any of Sublandlord's obligations under this
Sublease or receives a notice of default from Landlord under the Phase A Lease,
then Subtenant shall give written notice to Sublandlord specifying in what
manner Sublandlord has defaulted. If such default shall not be cured within a
reasonable time, but in no event later than thirty (30) days after Sublandlord's
receipt of such written notice from Subtenant (except that if such default
cannot be cured within said thirty (30) day period, this period shall be
extended for an additional reasonable time, provided that Sublandlord commences
to cure such default within such thirty (30) day period and proceeds diligently
thereafter to effect such cure as quickly as possible), then Subtenant shall be
entitled, at Subtenant's option, to cure such default and promptly collect from
Sublandlord Subtenant's reasonable expenses in so doing (including, without
limitation, reasonable attorneys' fees and court costs) unless such default by
Sublandlord is caused by a default of Subtenant hereunder (in which case
Sublandlord shall not be liable for Subtenant's costs to cure the default).
Subtenant shall not be required to wait the entire cure period provided for
herein if earlier action is required to prevent a termination by Landlord of the
Phase A Lease and Sublandlord has failed to take such earlier action.
Sublandlord shall not amend or modify the Phase A Lease in such a manner as to
materially adversely affect Subtenant's use of the Sublease Premises or increase
the obligations or decrease the rights of

                                       13
<PAGE>   14

Subtenant hereunder, without the prior written consent of Subtenant, which may
be granted or withheld at Subtenant's sole discretion. Anything contained in any
provision of this Sublease to the contrary notwithstanding, Subtenant agrees,
with respect to the Sublease Premises, to comply with and remedy any default in
this Sublease or the Phase A Lease which is Subtenant's obligation to cure,
within the period allowed to Sublandlord under the Phase A Lease, even if such
time period is shorter than the period otherwise allowed therein due to the fact
that notice of default from Sublandlord to Subtenant is given after the
corresponding notice of default from Landlord to Sublandlord. Sublandlord agrees
to forward to Subtenant, promptly upon receipt thereof by Sublandlord, a copy of
each notice of default received by Sublandlord in its capacity as Tenant under
the Phase A Lease. Subtenant agrees to forward to Sublandlord, promptly upon
receipt thereof, copies of any notices received by Subtenant from Landlord or
from any governmental authorities.

15. Notices. All notices, demands and requests shall be in writing and shall be
sent either by hand delivery or by a nationally recognized overnight courier
service (e.g., Federal Express), in either case return receipt requested, to the
address of the appropriate party. Notices, demands and requests so sent shall be
deemed given when the same are received. Notices and remittance of Rent to

with the exception of Cushman Realty Corporation ("BROKER"), no brokers were
involved in connection with the negotiation or consummation of this Sublease.
Sublandlord agrees to pay the commission of the Broker pursuant to a separate
agreement, which Sublandlord represents has been executed as of the date hereof.

acknowledges that it is subleasing the Sublease Premises "as-is" and that
Sublandlord is not making any representation or warranty concerning the
condition of the Sublease Premises and that Sublandlord is not obligated to
perform any work to prepare the Sublease Premises for Subtenant's occupancy.
Subtenant acknowledges that it is not authorized to make or do any alterations
or improvements in or to the Sublease Premises except as permitted by the
provisions of this Sublease and the Phase A Lease and that it must deliver the
Sublease Premises to Sublandlord on the Sublease Expiration Date in the
condition required by the Phase A Lease.

18. Consent of Landlord. Paragraph 21.A. of the Phase A Lease requires
Sublandlord to obtain the written consent of Landlord to this Sublease.
Sublandlord shall diligently pursue Landlord's consent to this Sublease promptly
following the execution and delivery of this Sublease by Sublandlord and
Subtenant.

19. Termination of the Phase A Lease. If for any reason the term of the Phase A
Lease shall terminate prior to the Sublease Expiration Date, this Sublease shall
automatically be terminated and Sublandlord shall not be liable to Subtenant by
reason thereof unless said termination shall have been caused by the default of
Sublandlord under the Phase A Lease, and said Sublandlord default was not as a
result of a Subtenant default hereunder. To the extent that the Phase A Lease
grants Sublandlord any discretionary right to terminate the Phase A Lease,
whether due to casualty, condemnation, or otherwise, Sublandlord shall not
exercise such right without the prior written consent of the Subtenant which may
be withheld by Subtenant in its sole and absolute discretion. If Landlord seeks
to terminate the Phase A Lease because of a default or alleged default by
Sublandlord under the Phase A Lease (other than a default or alleged default
caused by the default by Subtenant under this Sublease), Sublandlord shall take
all action required to reinstate the Phase A Lease. Further, if Rent is abated
under the Phase A Lease, Rent hereunder shall also be abated in the same
proportion.

20. Limitation of Estate. Subtenant's estate shall in all respects be limited
to, and be construed in a fashion consistent with, the estate granted to
Sublandlord by Landlord.

21. Confidentiality. The covenants, obligations and conditions contained in this
Sublease and the Phase A Lease shall remain strictly confidential. Subtenant
agrees to keep such terms, covenants, obligations and conditions strictly
confidential and not to disclose such matters to any other landlord, tenant,
prospective tenant, or broker. Notwithstanding the foregoing, Subtenant shall be
allowed to disclose the Sublease and all covenants, obligations and conditions
contained therein and the Phase A Lease, for business purposes only, to its
shareholders, lenders, attorneys

                                       15
<PAGE>   16

and accountants, and in any filing made by Subtenant with the Securities and
Exchange Commission or other governmental authorities in accordance with
applicable law.

22. Indemnity. Subtenant shall indemnify, defend, protect, and hold Sublandlord
harmless from and against all actions, claims, demands, costs, liabilities,
losses, reasonable attorneys' fees, damages, penalties, and expenses
(collectively "Claims") which may be brought or made against Sublandlord or
which Sublandlord may pay or incur to the extent caused by (i) a breach of this
Sublease by Subtenant, (ii) any violation of law by Subtenant or its employees,
agents, contractors or invitees ("Agents") relating to the use or occupancy of
the Sublease Premises, or (iii) the negligence or willful misconduct of
Subtenant or its Agents. Sublandlord shall indemnify, defend, protect, and hold
Subtenant harmless from and against all actions, claims, demands, costs,
liabilities, losses, reasonable attorneys' fees, damages, penalties and expenses
which may be brought or made against Subtenant or which Subtenant may pay or
incur to the extent caused by (i) the negligence or willful misconduct of
Sublandlord or its Agents occurring on or about the Project or Sublease
Premises; (ii) the failure by Sublandlord to comply with or perform its
obligations under the Phase A Lease and/or this Sublease, and (iii) a breach by
Sublandlord of any of its representations or warranties to Subtenant under this
Sublease.

23. Permitted Use. The Sublease Premises shall be used for general office space
and any other legal permitted uses compatible with the City of San Diego's MLI
zone and the MCAS Miramar Comprehensive Land Use Plan and otherwise compatible
with comparable office projects. The Occupancy Density shall not exceed 4
persons per 1,000 square feet.

24. Mutual Waiver of Subrogation. The waiver of subrogation provision set forth
in Paragraph 9 of the Phase A Lease shall be deemed a three party agreement
binding among and inuring to the benefit of Sublandlord, Subtenant and Landlord
(by reason of its consent to hereto).

25. Representations. Sublandlord represents to Subtenant that (A) the Phase A
Lease is in full force and effect, (B) the copy of the Phase A Lease which is
attached to this Sublease as EXHIBIT A is a true, correct and complete copy of
the Phase A Lease, (C) to Sublandlord's best knowledge, no default exists on the
part of Sublandlord, or has there occurred any event which, with the giving of
notice or passage of time or both, could constitute such a default or event of
default, and (D) to Sublandlord's best knowledge, there are no pending or
threatened actions, suits or proceedings before any court or administrative
agency against Sublandlord which could, in the aggregate, adversely affect the
Sublease Premises or of Sublandlord to perform its obligations under the
Sublease, and Sublandlord is not aware of any facts which might result in any
actions, suits or proceedings.

26. Entire Agreement. It is understood and acknowledged that there are no oral
agreements between the parties hereto affecting this Sublease and this Sublease
supersedes and cancels any and all previous negotiations, arrangements,

covenants, conditions or provisions of this Sublease can be modified, deleted or
added to except in writing signed by the parties hereto. All negotiations and
oral agreements acceptable to both parties have been merged into and are
included herein. There are no other representations or warranties between the
parties, and all reliance with respect to representations is based totally upon

                          CONSENT TO SUBLEASE AGREEMENT

        This Consent to Sublease Agreement (this "AGREEMENT") is made as of
December 13, 1999 by and among Spieker Properties, L.P., a California limited
partnership ("MASTER LANDLORD"), Franklin Resources, Inc., a Delaware
corporation ("SUBLANDLORD"), and MP3.com, Inc., a Delaware corporation
("SUBTENANT").

                                    RECITALS

        This Agreement is made with regard to the following facts:

        A. Master Landlord is the owner of approximately 29 acres and up to
approximately 591,000 square feet (existing, under construction or planned) in 9
buildings known as Bridge Pointe Corporate Centre within the Eastgate Technology
Park in San Diego, California (the "PROJECT"). Phase A of the Project consists
of 4 existing buildings known as "Building 1" (also referred to as the "PHASE
A-1 PREMISES") located at 4770 Eastgate Mall, "Building 2" (also referred to as
the "ADC TELECOMMUNICATIONS PREMISES") located at 4790 Eastgate Mall, "Building
3" (also referred to as the "PHASE A-2 PREMISES") located at 4760 Eastgate Mall
and "Building 4" (also referred to as the "PHASE A-3 PREMISES") located at 4780
Eastgate Mall. Phase B of the Project consists of 2 buildings under construction
known as "Building 5" (also referred to as the "PHASE B-2 PREMISES") located at
4810 Eastgate Mall and "Building 6" (also referred to as the "PHASE B-1
PREMISES") located at 4820 Eastgate Mall. Phase C of the Project consists of 3
planned buildings known as "Buildings 7 through 9".

        B. Master Landlord and Sublandlord entered into a lease dated September
2, 1998, as amended by that certain First Amendment to Lease dated as of March
15, 1999 between Master Landlord and Sublandlord (collectively, the "PHASE A
LEASE") whereby Master Landlord leased to Sublandlord the Phase A-2 Premises and
the Phase A-3 Premises, upon the terms and conditions contained therein.
Furthermore, Master Landlord and Sublandlord entered into another lease dated
September 2, 1998, between Master Landlord and Sublandlord (the "PHASE B LEASE")
whereby Master Landlord leased to Sublandlord the Phase B-1 Premises and the
Phase B-2 Premises, upon the terms and conditions contained therein.

        D. Under the terms of Paragraph 21 of the Phase A Lease, Sublandlord has
requested Master Landlord's consent to the Sublease Agreement dated December 13,
1999 between Sublandlord and Subtenant (the "SUBLEASE"), pursuant to which
Sublandlord will sublease to Subtenant the Phase A-3 Premises and grant options
on the Phase A-2 Premises and the Phase B-2 Premises, as more particular
described in the Sublease (the "SUBLEASED Premises"). A copy of the Sublease is
attached to this Agreement as EXHIBIT A.

        E. Master Landlord is willing to consent to the Sublease on the terms
and conditions contained in this Agreement.

<PAGE>   24

        NOW THEREFORE, in consideration of the mutual covenants contained in
this Agreement, and for valuable consideration, the receipt and sufficiency of
which are acknowledged by the parties, the parties agree as follows.

               1. MASTER LANDLORD'S CONSENT. Master Landlord consents to the
Sublease. This consent is granted only on the terms and conditions stated in
this Agreement. Master Landlord is not bound by any of the terms, covenants, or
conditions of the Sublease, except as set forth in Section 2.2 below. The
Sublease is subject and subordinate to the Master Lease.

               2. LIMITS OF CONSENT.

                      2.1 NONRELEASE OF SUBLANDLORD; FURTHER TRANSFERS. Neither
the Sublease nor this Agreement will:

                             (a) release Sublandlord from any liability, whether
past, present or future, under the Master Lease;

                             (b) alter the primary liability of Sublandlord to
pay the Rent and perform all of Tenant's obligations under the Master Lease
(including the payment of all bills rendered by Master Landlord for charges
incurred by Subtenant for services and materials supplied to the Subleased
Premises); or

                             (c) be construed as a waiver of Master Landlord's
right to consent to any proposed transfer after the date hereof by Sublandlord
under the Master Lease or Subtenant under the Sublease, or as a consent to any
portion of the Subleased Premises being used or occupied by any other party.

                      Master Landlord may consent to the subsequent sublease and
assignment of the Sublease or any amendments or modifications to the Sublease
without notifying Sublandlord or anyone else liable under the Master Lease,
including any guarantor of the Master Lease, and without obtaining their
consent. No such action by Master Landlord will relieve those persons from any
liability to Master Landlord or otherwise with regard to the Subleased Premises.
Notwithstanding the foregoing, nothing contained herein shall diminish any
obligation of Subtenant to obtain Sublandlord's approval prior to taking any
such actions.

                      2.2 CONSENT TO CERTAIN PROVISIONS. Master Landlord
specifically consents and agrees to be bound by the following provisions of the
Sublease: Paragraphs 23 and 24.

               3. RELATIONSHIP WITH MASTER LANDLORD

                                        2
<PAGE>   25

                      3.1 EFFECT OF SUBLANDLORD DEFAULT UNDER MASTER LEASE. If
after the expiration of any applicable cure period Sublandlord defaults in the
performance of its obligations under the Master Lease and the Master Lease
terminates, Master Landlord shall notify Subtenant and, without limiting its
other rights and remedies, by notice to Sublandlord and Subtenant, elect to
receive and collect, directly from Subtenant, all rent and any other sums owing
and to be owed under the Sublease, as further set forth in Section 3.2 below.

                      3.2 MASTER LANDLORD'S ELECTION TO RECEIVE RENTS. Master
Landlord will not, as a result of the Sublease, or as a result of the collection
of rents or any other sums from Subtenant under Section 3.1 above, be liable to
Subtenant for any failure of Sublandlord to perform any obligation of
Sublandlord under the Sublease.

                      Sublandlord irrevocably authorizes and directs Subtenant,
on receipt of any written notice from Master Landlord stating that a default
exists in the performance of Sublandlord's obligations under the Master Lease,
to pay to Master Landlord the rents and any other sums due and to become due
under the Sublease. Sublandlord agrees that Subtenant has the right to rely on
any such statement from Master Landlord, and that Subtenant will pay those rents
and other sums to Master Landlord without any obligation or right to inquire as
to whether a default exists and despite any notice or claim from Sublandlord to
the contrary. Sublandlord will not have any right or claim against Subtenant for
those rents or other sums paid by Subtenant to Master Landlord. Master Landlord
will credit Sublandlord with any rent received by Master Landlord under this
assignment, but the acceptance of any payment on account of rent from Subtenant
as the result of a default by Sublandlord will not: (a) except as set forth in
Section 3.3 below, be an attornment by Master Landlord to Subtenant or by
Subtenant to Master Landlord; (b) be a waiver by Master Landlord of any
provision of the Master Lease; or (c) release Sublandlord from any liability
under the terms, agreements, or conditions of the Master Lease. Except as set
forth in Section 3.3 below, no payment of rent by Subtenant directly to Master
Landlord, regardless of the circumstances or reasons for that payment, will be
deemed an attornment by Subtenant to Master Landlord in the absence of a
specific written agreement signed by Master Landlord to that effect.

                      3.3 TENANT'S ATTORNMENT. In the event the Master Lease is
terminated prior to the expiration of the term of the Sublease, Master Landlord
shall have the right, pursuant to notice to Subtenant, to succeed to
Sublandlord's interest in the Sublease and cause Subtenant to attorn to Master
Landlord. Furthermore, Master Landlord shall recognize Subtenant's right to
possession of the Premises as provided for in the Sublease and shall not disturb
Subtenant's right to possession of the Premises so long as an event of default
does not exist in the performance of Subtenant's obligations under the Sublease.
Master Landlord will assume the obligation of Sublandlord under the Sublease
from the time of the exercise of the option, but Master Landlord will not be:

                             (a) liable for any rent paid by Subtenant to
Sublandlord more than one month in advance, or any security deposit paid by
Subtenant to Sublandlord;

                                       3
<PAGE>   26

                             (b) liable for any act or omission of Sublandlord
under the Master Lease or for any default of Sublandlord under the Sublease
which occurred prior to the Master Landlord's assumption;

                             (c) subject to any defenses or offsets that
Subtenant may have against Sublandlord which arose prior to Master Landlord's
assumption; or

                             (d) bound by any changes or modifications made to
the Sublease without the written consent of Master Landlord.

               Upon receipt of the notice from Master Landlord, Subtenant shall
attorn to Master Landlord and perform all of the Subtenant's obligations under
the Sublease directly to Master Landlord, just as if Master Landlord were the
"Sublessor" under the Sublease. If and so long as Subtenant is not in
substantial and material default (beyond any notice and cure periods) under the
Sublease, Master Landlord shall continue to recognize the interest of Subtenant
created under the Sublease and the Sublease shall continue with the same force
and effect as if Master Landlord and Subtenant had entered into a Sublease on
the same terms and conditions as those contained in the Sublease.

               Sublandlord and Subtenant shall not enter into any agreement
which amends the Sublease without Master Landlord's prior written consent, which
shall not be unreasonably withheld or delayed. Any amendment of the Sublease in
violation of this provision shall have no force or effect on Master Landlord.

               4. CONSIDERATION FOR SUBLEASE. Sublandlord and Subtenant
represent and warrant that there are no additional payments of rent or any other
consideration of any type which has been paid or is payable by Subtenant to
Sublandlord in connection with the Sublease, other than as disclosed in the
Sublease.

               5. GENERAL PROVISIONS

                      5.1 BROKERAGE COMMISSION. Sublandlord and Subtenant agree
that Master Landlord will not be liable for any brokerage commission or finder's
fee in connection with the consummation of the Sublease or this Agreement.
Sublandlord and Subtenant will protect, defend, indemnify, and hold Master
Landlord harmless from any brokerage commission or finder's fee in connection
with the consummation of the Sublease or this Agreement, and from any cost or
expense (including attorney fees) incurred by Master Landlord in resisting any
claim for any such brokerage commission or finder's fee. The provisions of this
Section 5.1 shall survive the expiration or earlier termination of the Sublease
and this Agreement.

                      5.2 NOTICE. Any notice that may or must be given by any
party under this Agreement will be delivered (i) personally, (ii) by certified
mail, return receipt requested, or (iii) by a nationally recognized overnight
courier, addressed to the party to whom it is intended. Any notice given to the
Master Landlord, Sublandlord or Subtenant shall be sent to the respective
address set forth on the signature page below, or to such other address as that
party may designate for service of notice by a notice given in accordance with
the provisions of this Section 5.2.

                                       4
<PAGE>   27

Master Landlord and Sublandlord agree to send to Subtenant copies of all notices
of default and other formal notices that may require action by Sublandlord or
Subtenant under the Master Lease.

                      5.3 CONTROLLING LAW. The terms and provisions of this
Agreement will be construed in accordance with, and will be governed by, the
laws of the State of California.

                      5.4 ENTIRE AGREEMENT; WAIVER. This Agreement constitutes
the final, complete and exclusive statement between the parties to this
Agreement pertaining to the terms of Master Landlord's consent to the Sublease,
supersedes all prior and contemporaneous understandings or agreements of the
parties, and is binding on and inures to the benefit of their respective heirs,
representatives, successors and assigns.

                      5.5 WAIVER OF JURY TRIAL; ATTORNEY FEES. If any party
commences litigation against any other party for the specific performance of
this Agreement, for damages for the breach hereof or otherwise for enforcement
of any remedy hereunder, the parties waive any right to a trial by jury and, in
the event of any commencement of litigation, the prevailing party shall be
entitled to recover from the applicable party such costs and reasonable attorney
fees as may have been incurred.

                      5.6 Non-Disturbance From Lenders. Master Landlord
represents and warrants that there are no deeds of trust, mortgages, ground
leases or other liens affecting the Project as of the date hereof. With respect
to any future mortgages, deeds of trust or other liens or ground leases entered
into by and between Landlord and any beneficiary of any deed of trust or other
such lien granted by Landlord or any ground lessor or otherwise encumbering the
Building (collectively referred to as "Landlord's Mortgagee"), Landlord shall
use commercially reasonable efforts to secure and deliver to Tenant recordable
Non-Disturbance Agreements from, and executed by, all Landlord's Mortgagees for
the benefit of Tenant as a condition precedent to subordination and attornment
to any such future Landlord Mortgagee.

                                       5

        The parties have executed this Consent to Sublease Agreement as of the
above date.

                                      LEASE

THIS LEASE is made as of the 2nd day of September, 1998, by and between Spieker
Properties, L.P., a California limited partnership (hereinafter called
"LANDLORD"), and Franklin Resources, Inc., a Delaware corporation (hereinafter
called "TENANT").

                                   1. PREMISES

    Landlord leases to Tenant and Tenant leases from Landlord, upon the terms
and conditions hereinafter set forth, those premises (the "PREMISES") outlined
in red on EXHIBIT B and described in the Basic Lease Information. The Premises
shall comprise all of the buildings (each individually a "BUILDING") and a
PORTION OF THE project (the "PROJECT"), which may consist of more than one
building and additional facilities, as described in the Basic Lease Information.
The Building and Project are outlined in blue and green respectively on EXHIBIT
B. Landlord and Tenant acknowledge that, subject to the terms and provisions of
this Lease, physical changes may occur from time to time in the Premises,
Building or Project, and that the number of buildings and additional facilities
which constitute the Project may change from time to time, which may result in
an adjustment in Tenant's Proportionate Share, as defined in the Basic Lease
Information, as provided in Paragraph 7.A.

                      2. POSSESSION AND LEASE COMMENCEMENT

B.      CONSTRUCTION OF IMPROVEMENTS. If this Lease pertains to a Building to be
constructed or improvements to be constructed within a Building, the provisions
of this Paragraph 2.B. shall apply in lieu of the provisions of Paragraph 2.A.
above and the term commencement date ("TERM COMMENCEMENT DATE") shall be the
earlier of the date on which: (1) Tenant takes possession of some or all of the
Premises for purposes of the commencement of the conduct of its business
therein; or (2) the improvements to be constructed or performed in the Premises
by Landlord (if any) shall have been substantially completed in accordance with
the Plans described on EXHIBIT C as certified by the architect, Devcon
Construction Incorporated, in writing to Tenant and Landlord (subject to mutual
approval by Landlord and Tenant), and Tenant's taking of possession of the
Premises or any part thereof for purposes of other than the installation of
telephone or data cabling or the installation of furniture or furniture systems
shall constitute Tenant's confirmation of substantial completion for all
purposes hereof (subject to the completion by Landlord of any punch list items
and any latent defects not visually discoverable by Tenant upon a reasonably
diligent inspection and which are identified in writing by Tenant within six (6)
months of the Tenant's occupancy of each Building), whether or not substantial
completion of other portions of the Building or Project shall have occurred. If
for any reason beyond Landlord's reasonable control Landlord cannot deliver
possession of the subject portion of the Premises to Tenant on the scheduled
Term Commencement Date, Landlord shall not be subject to any liability therefor,
nor shall Landlord be in default hereunder nor shall such failure affect the
validity of this Lease, and Tenant agrees to accept possession of other portions
of the Premises at such time as such improvements have been substantially
completed, which date shall then be deemed the Term Commencement Date; provided,
however, that if Landlord fails to tender possession of any portion of the
Premises, subject to Paragraph 35 of this Lease, within ninety (90) days of the
scheduled Term Commencement Date with respect to each Building, then Tenant,
upon not less than thirty (30) days prior written notice to Landlord shall have
the right to terminate this Lease with respect to each Building, unless within
such thirty (30) day period Landlord tenders possession of each Building in the
condition required by this Lease. Tenant shall not be liable for any Rent for
any period prior to the Term Commencement Date (but without affecting any
obligations of Tenant under any improvement agreement appended to this Lease).
In the event of any dispute as to substantial completion of work performed or
required to be performed by Landlord, the certificate of Landlord's architect or
general contractor shall be conclusive. Substantial completion shall have
occurred notwithstanding Tenant's submission of a punchlist to Landlord, which
Tenant shall submit, if at all, within seven (7) business days after the Term
Commencement Date or otherwise in accordance with any improvement agreement
appended to this Lease. Upon Landlord's request, Tenant shall promptly execute
and return to Landlord a "Start-Up Letter" in which Tenant shall agree, among
other things, to acceptance of the Premises (subject to any punchlist exceptions
according to Paragraph 6.C of EXHIBIT C) and to the determination of the Term
Commencement Date, in accordance with the terms of this Lease, but Tenant's
failure or refusal to do so shall not negate Tenant's acceptance of the Premises
or affect determination of the Term Commencement Date.

                                     3. TERM

    The term of this Lease (the "TERM") shall commence on the Term Commencement
Date and continue in full force and effect for the number of months specified as
the Length of Term in the Basic Lease Information or until this Lease is
terminated as otherwise provided herein. If the Term Commencement Date is a date
other than the first day of the calendar month, the Term shall be the number of
months of the Length of Term in addition to the remainder of the calendar month
following the Term Commencement Date.

                                     4. USE

A. GENERAL. Tenant shall use the Premises for the permitted use specified in the
Basic Lease Information ("PERMITTED USE") and for no other use or purpose,
without Landlord's consent, which consent shall not be unreasonably withheld,
delayed or conditioned. Tenant shall control Tenant's employees, agents,
customers, visitors, invitees, licensees, contractors, assignees and subtenants
(collectively, "TENANT'S PARTIES") in such a manner that Tenant and Tenant's
Parties cumulatively do not exceed the occupancy density (the "OCCUPANCY
DENSITY") or the parking density specified in the Basic Lease Information (the
"PARKING DENSITY") at any time. So long as Tenant is occupying the Premises,
Tenant and Tenant's Parties shall have the nonexclusive right to use, without
paying any fee or charge therefor, in common with other parties occupying the
Project, the parking areas, driveways and other common areas of

                                       4
<PAGE>   34

the Building and Project, subject to the terms of this Lease and such rules and
regulations as Landlord may from time to time reasonably prescribe upon written
notice to Tenant. Further, Landlord and Tenant acknowledge that Tenant's
Occupancy Density exceeds Tenant's Parking Density, however, Landlord shall not
be obligated to Tenant to provide additional parking in the event the Occupancy
Density causes the Parking Density to be exceeded. In the event Tenant's Parking
Density is exceeded, Tenant shall use its commercially reasonable efforts to
immediately cure this condition. Landlord reserves the right to the extent it is
commercially reasonable to do so, upon reasonable prior written notice to
Tenant, without liability to Tenant, and without the same constituting an actual
or constructive eviction, to alter or modify the common areas from time to time,
including the location and configuration thereof, and the amenities and
facilities which Landlord may determine to provide from time to time, provided
that no such changes shall unreasonably affect access to or visibility of the
Premises and all such changes shall be consistent with the operation of
comparable first-class business parks in San Diego County, California.

B. LIMITATIONS. Tenant shall not permit any odors, smoke, dust, gas, substances,
noise or vibrations to emanate from the Premises or from any portion of the
common areas as a result of Tenant's or any Tenant's Party's use thereof, nor
take any action which would constitute a nuisance or would unreasonably disturb,
obstruct or endanger any other tenants or occupants of the Project or elsewhere,
or interfere with their use of their respective premises or common areas.

C. COMPLIANCE WITH REGULATIONS. By entering the Premises for purposes of the
commencement of the conduct of Tenant's business, Tenant accepts the Premises in
the condition existing as of the date of such entry subject to the completion by

including zoning ordinances and regulations, including the MCAS Miramar
Comprehensive Land Use Plan ("CLUP") attached hereto as Exhibit E of this Lease,
and covenants, easements and restrictions of record governing and relating to

of Hazardous Materials (hereinafter defined) (collectively "REGULATIONS").
Tenant shall at its sole cost and expense obtain any and all licenses or permits
necessary for Tenant's use of the Premises. Tenant shall at its sole cost and
expense promptly comply with the requirements of any board of fire underwriters
or other similar body now or hereafter constituted. Tenant shall not do or
permit anything to be done in, on, under or about the Project or bring or keep
anything which will in any way increase the rate of any insurance upon the

cancellation of said insurance or otherwise affect said insurance in any manner.
Tenant shall indemnify, defend (by counsel reasonably acceptable to Landlord),
protect and hold Landlord harmless from and against any loss, cost, expense,
damage, attorneys' fees or liability arising out of the failure of Tenant to
comply with any Regulation. Tenant's obligations pursuant to the foregoing
indemnity shall survive the expiration or earlier termination of this Lease.

D. HAZARDOUS MATERIALS. As used in this Lease, "HAZARDOUS MATERIALS" shall
include, but not be limited to, hazardous, toxic and radioactive materials and
those substances defined as "hazardous substances," "hazardous materials,"
"hazardous wastes," "toxic substances," or other similar designations in any
Regulation. Tenant's Hazardous Materials Declaration is attached hereto as
EXHIBIT D. Tenant shall not cause, or allow any of Tenant's Parties to cause,
any Hazardous Materials to be handled, used, generated, stored, released or
disposed of in, on, under or about the Premises, the Building or the Project or
surrounding land or environment in violation of any Regulations. Tenant must
obtain Landlord's written consent prior to the introduction of any Hazardous
Materials onto the Project. Notwithstanding the foregoing, Tenant may handle,
store, use and dispose of products containing small quantities of Hazardous
Materials for "general office purposes" (such as toner for copiers) to the
extent customary and necessary for the Permitted Use of the Premises; provided
that Tenant shall always handle, store, use, and dispose of any such Hazardous
Materials in a safe and lawful manner and never allow such Hazardous Materials
to contaminate the Premises, Building, or Project or surrounding land or
environment. Tenant shall immediately notify Landlord in writing of any
Hazardous Materials' contamination of any portion of the Project of which Tenant
becomes aware, whether or not caused by Tenant. If, but only if, Landlord has a
reasonable basis to believe that Tenant has introduced any Hazardous Materials
onto the Premises, then Landlord shall have the right at all reasonable times to
inspect the Premises and to conduct tests and investigations to determine
whether Tenant is in compliance with the foregoing provisions, the reasonable
and actual costs of all such inspections, tests and investigations to be borne
by Tenant. Tenant shall indemnify, defend (by counsel reasonably acceptable to
Landlord), protect and hold Landlord harmless from and against any and all
claims, liabilities, losses, costs, loss of rents, liens, damages, injuries or
expenses (including attorneys' and consultants' fees and court costs), demands,
causes of action, or judgments directly or indirectly arising out of or related
to the use, generation, storage, release, or disposal of Hazardous Materials by
Tenant or any of Tenant's Parties in, on, under or about the Premises, the
Building or the Project or surrounding land or environment, which indemnity
shall include, without limitation, damages for personal or bodily injury,
property damage, damage to the environment or natural resources occurring on or
off the Premises, losses attributable to diminution in value or adverse effects
on marketability, the cost of any investigation, monitoring, government
oversight, repair, removal, remediation, restoration, abatement, and disposal,
and the preparation of any closure or other required plans, whether such action
is required or necessary prior to or following the expiration or earlier
termination of this Lease. Neither the consent by Landlord to the use,
generation, storage, release or disposal of Hazardous Materials nor the strict
compliance by Tenant with all laws pertaining to Hazardous Materials shall
excuse Tenant from Tenant's obligation of indemnification pursuant to this
Paragraph 4.D. Tenant's obligations pursuant to the foregoing indemnity shall
survive the expiration or earlier termination of this Lease.

                            5. RULES AND REGULATIONS

rules and regulations. Landlord shall not be responsible to Tenant for the
non-compliance by any other tenant or occupant of the Building or Project with
any of such rules and regulations, any other tenant's or occupant's lease or any
Regulations, provided Landlord shall administer compliance with such rules in a
nondiscriminatory manner.

hereunder, Tenant shall pay as Additional Rent, Tenant's Proportionate Share of
the Building and/or Project (as applicable), as defined in the Basic Lease
Information, of Operating Expenses (defined below) in the manner set forth
below. Tenant shall pay the applicable Tenant's Proportionate Share of each such

buildings which constitute the Project increases or decreases, or if physical
changes are made to the Building or Project or the configuration of any thereof,
Landlord may at its discretion reasonably adjust Tenant's Proportionate Share of
the Building or Project to reflect the change. Landlord's determination of
Tenant's Proportionate Share of the Project shall be conclusive so long as it is
reasonably and consistently applied. "OPERATING EXPENSES" shall mean all
expenses and costs of every kind and nature which Landlord shall reasonably pay
or become obligated to pay, because of or in connection with the , management,
maintenance, repair, preservation, replacement and operation of the Building or
Project and its supporting facilities and such additional facilities now and in
subsequent years as may be determined by Landlord to be necessary or desirable
to the Building and/or Project (as determined in a reasonable manner) other than
those expenses and costs which are specifically attributable to Tenant or which
are expressly made the financial responsibility of Landlord or specific tenants
of the Building or Project pursuant to this Lease. Operating Expenses shall
include, but are not limited to, the following:

        (1) TAXES. All real property taxes and general assessments, possessory
        interest taxes, sales taxes, personal property taxes, business or
        license taxes or fees, gross receipts taxes, service payments in lieu of
        such taxes or fees, annual or periodic license or use fees, excises,
        transit charges imposed generally and not in connection with the initial
        development of the Project, and other impositions, general and special,
        ordinary and extraordinary, unforeseen as well as foreseen, of any kind
        (including fees "in-lieu" of any such tax or assessment) which are now
        or hereafter assessed, levied, charged, confirmed, or imposed by any
        public authority upon the Building or Project, its operations or the
        Rent (or any portion or component thereof), or any tax, assessment or
        fee imposed in substitution, partially or totally, of any of the above.
        Operating Expenses shall also include any taxes, assessments,
        reassessments, or other fees or impositions with respect to the
        development, leasing, management, maintenance, alteration, repair, use
        or occupancy by Tenant of the Premises, Building or Project or any
        portion thereof, including, without limitation, by or for Tenant, and
        all increases therein or reassessments thereof whether the increases or
        reassessments result from increased rate and/or valuation (whether upon
        a transfer of the Building or Project or any portion thereof or any
        interest therein or for any other reason). Operating Expenses shall not
        include inheritance or estate taxes imposed upon or assessed against the
        interest of any person in the Project, or taxes computed upon the basis
        of the net income of any owners of any interest in the Project. If it
        shall not be lawful for Tenant to reimburse Landlord for all or any part
        of such taxes, the monthly rental payable to Landlord under this Lease
        shall be revised to net Landlord the same net rental after imposition of
        any such taxes by Landlord as would have been payable to Landlord prior
        to the payment of any such taxes. Notwithstanding anything set forth in
        this Lease to the contrary, in no event shall "Taxes" include any fees,
        costs or exactions incurred by Landlord in connection with obtaining the
        right to develop the Project (exclusive of Tenant Improvements),
        including, but not limited to, any fees for schools, parks, traffic,
        sewer and fire protection, or any special assessments used to finance
        any portion of the Project, including any off-site roadway or utility
        facilities.

        (2) INSURANCE. All insurance premiums and costs, including, but not
        limited to, any deductible amounts, premiums and other costs of
        insurance reasonably and actually incurred by Landlord, including for
        the insurance coverage set forth in Paragraph 8.A. herein. In an event
        wherein a deductible may be greater than Fifty Thousand Dollars
        ($50,000.00) said deductible amount shall be amortized over the greater
        of (i) the remaining Term of this Lease or (ii) three (3) years.

               of the Building or Project, which determination shall be at
               Landlord's discretion, except for: those items expressly made the
               financial responsibility of Landlord pursuant to Paragraph 10
               hereof; those items to the extent paid for by the proceeds of
               insurance or which are covered under warranties of the
               contractor, manufacturer or supplier thereof; and those items
               attributable solely or jointly to specific tenants of the
               Building or Project.

               determine, together with interest on the unamortized balance at
               the publicly announced "prime rate" charged by Wells Fargo Bank,
               N.A. (San Francisco) or its successor at the time such
               improvements or capital assets are constructed or acquired, plus
               two (2) percentage points, or in the absence of such prime rate,

               designated) rate as published by any national financial
               publication selected by Landlord, plus four (4) percentage
               points, but in no event more than the maximum rate permitted by
               law, plus reasonable financing charges. Landlord shall be
               responsible, at its sole cost and expense, for performing all
               work to the Buildings (exclusive of Tenant Improvements) or the
               common areas necessary to cause the Project to conform to
               regulations applicable as of the Term Commencement Date.

any fiscal year of the Term as determined by Landlord, an adjustment may be made

        (xxviii)  Landlord's general corporate overhead and general and
                  administrative expenses; and

        (xxix)    costs incurred by Landlord due to the violation by Landlord or
                  any tenant of the terms and conditions of any lease of space
                  in the Project.

         Notwithstanding anything herein to the contrary, in any instance
wherein Landlord, in Landlord's reasonable discretion, deems Tenant to be
responsible for any amounts greater than Tenant's Proportionate Share, Landlord
shall have the right to reasonably allocate costs in any manner Landlord
reasonably deems appropriate.

        The above enumeration of services and facilities shall not be deemed to
impose an obligation on Landlord to make available or provide such services or
facilities except to the extent if any that Landlord has specifically agreed
elsewhere in this Lease to make the same available or provide the same; provided
that Landlord shall operate and maintain the Project in a manner reasonably
comparable to other comparable first-class business park projects in San Diego
County. Without limiting the generality of the foregoing, Tenant acknowledges
and agrees that it shall be responsible for providing adequate security for its
use of the Premises, the Building and the Project and that Landlord shall have
no obligation or liability with respect thereto, except to the extent if any
that Landlord has specifically agreed elsewhere in this Lease to provide the
same.

B. PAYMENT OF ESTIMATED OPERATING EXPENSES. "ESTIMATED OPERATING EXPENSES" for
any particular year shall mean Landlord's reasonable estimate of the Operating
Expenses for such fiscal year made with respect to such fiscal year as
hereinafter provided. Landlord shall have the right from time to time to revise
its fiscal year and interim accounting periods so long as the periods as so
revised are reconciled with prior periods in a reasonable manner. During the
last month of each fiscal year during the Term, or as soon thereafter as
practicable, but in any event by April 30 of the following year, Landlord shall
give Tenant written notice of the Estimated Operating Expenses for the ensuing
fiscal year. Tenant shall pay Tenant's Proportionate Share of the Estimated
Operating Expenses with installments of Base Rent for the fiscal year to which
the Estimated Operating Expenses applies in monthly installments on the first
day of each calendar month during such year, in advance. Such payment shall be
construed to be Additional Rent for all purposes hereunder. If at any time
during the course of the fiscal year, Landlord determines that Operating
Expenses are projected to vary from the then Estimated Operating Expenses by
more than five percent (5%), Landlord may, by written notice to Tenant stating
with specificity the basis for such readjustment, revise the Estimated Operating
Expenses for the balance of such fiscal year, and Tenant's monthly installments
for the remainder of such year shall be adjusted so that by the end of such
fiscal year Tenant has paid to Landlord Tenant's Proportionate Share of the
revised Estimated Operating Expenses for such year, such revised installment
amounts to be Additional Rent for all purposes hereunder.

C. COMPUTATION OF OPERATING EXPENSE ADJUSTMENT. "OPERATING EXPENSE ADJUSTMENT"
shall mean the difference between Estimated Operating Expenses and actual
Operating Expenses for any fiscal year determined as hereinafter provided.
Within one hundred twenty (120) days after the end of each fiscal year, or as
soon thereafter as practicable but in any event by June 30 of such year,
Landlord shall deliver to Tenant a statement of actual Operating Expenses for
the fiscal year just ended, accompanied by a computation of Operating Expense
Adjustment. If such statement shows that Tenant's payment based upon Estimated
Operating Expenses is less than Tenant's Proportionate Share of Operating
Expenses, then Tenant shall pay to Landlord the difference within thirty (30)
days after receipt of such statement, such payment to constitute Additional Rent
for all purposes hereunder. If such statement shows that Tenant's payments of
Estimated Operating Expenses exceed Tenant's Proportionate Share of Operating
Expenses, then (provided that Tenant is not in default under this Lease)
Landlord shall pay to Tenant the difference within thirty (30) days after
delivery of such statement to Tenant. If this Lease has been terminated or the
Term hereof has expired prior to the date of such statement, then the Operating
Expense Adjustment shall be paid by the appropriate party within thirty (30)
days after the date of delivery of the statement. Should this Lease commence or
terminate at any time other than the first day of the fiscal year, Tenant's
Proportionate Share of the Operating Expense Adjustment shall be prorated based
on a month of 30 days and the number of calendar months during such fiscal year
that this Lease is in effect. Notwithstanding anything to the contrary contained
in Paragraph 7.A or 7.B, Landlord's failure to provide any notices or statements
within the time periods specified in those paragraphs shall in no way excuse
Tenant from its obligation to pay Tenant's Proportionate Share of Operating
Expenses.

D. NET LEASE. This shall be a triple net Lease and Base Rent shall be paid to
Landlord absolutely net of all costs and expenses, except as specifically
provided to the contrary in this Lease. The provisions for payment of Operating
Expenses and the Operating Expense Adjustment are intended to pass on to Tenant
and reimburse Landlord for all costs and expenses of the nature described in
Paragraph 7.A. incurred in connection with the management, maintenance, repair,
preservation, replacement and operation of the Building and/or Project and its
supporting facilities and such additional facilities now and in subsequent years
as may be determined by Landlord to be necessary or desirable to the Building
and/or Project.

E. TENANT AUDIT. If Tenant shall dispute the amount set forth in any statement
provided by Landlord under Paragraph 7.B. or 7.C. above, Tenant shall have the
right, not later than six (6) months following receipt of such statement and
upon the condition that Tenant shall first deposit with Landlord the full amount
in dispute, to cause Landlord's books and records with respect

                                       8
<PAGE>   38

to Operating Expenses for such fiscal year to be audited by certified public
accountants selected by Tenant and subject to Landlord's reasonable right of
approval. The Operating Expense Adjustment shall be appropriately adjusted on
the basis of such audit. If such audit discloses a liability for a refund in
excess of five percent (5%) of Tenant's Proportionate Share of the Operating
Expenses previously reported, the cost of such audit shall be borne by Landlord;
otherwise the cost of such audit shall be paid by Tenant. If Tenant shall not
request an audit in accordance with the provisions of this Paragraph 7.E. within
six (6) months after receipt of Landlord's statement provided pursuant to
Paragraph 7.B. or 7.C., such statement shall be final and binding for all
purposes hereof, absent manifest error.

F. CALCULATION OF OPERATING EXPENSES. Operating Expenses shall be calculated and
determined in accordance with the following general principles:

        (1)  RECOVERY LIMITED TO ACTUAL COSTS. Landlord shall not recover the
             cost of any item more than once.

        (2)  ARM'S LENGTH. All services rendered to and materials supplied to
             the Project shall be rendered or supplied at a cost comparable to
             those charged in arm's length transactions for similar services or
             materials rendered or supplied for similar purposes to comparable
             buildings in San Diego County.

        (3)  REIMBURSEMENTS. All discounts, reimbursements, rebates, refunds or
             credits (collectively, "Reimbursements") attributable to Operating
             Expenses received by Landlord in a particular year shall be
             deducted from Operating Expenses in the year the same are received;
             provided, however, if a particular Reimbursement exceeds Fifty
             Thousand Dollars ($50,000.00) and applies to a prior year, such
             Reimbursement shall be applied to such prior year (and Tenant's
             Proportionate Share thereof shall be promptly refunded).

        (4)  NON-PROJECT EXCLUSIVE EXPENSES. Whenever expenses are paid or
             incurred by Landlord as a result of activities that are not
             exclusively rendered to the Project, only that portion that can be
             reasonably allocated to the Project shall be included within
             Operating Expenses.

        (5)  INSTALLMENTS. All assessments and premiums of Operating Expenses
             which can be paid or incurred by Landlord in annual installments
             shall be paid by Landlord in the maximum number of annual
             installments permitted by law and shall not be included as
             Operating Expenses except in the calculation year in which the
             installments are actually paid; provided, however, that if the
             then-prevailing practice in other comparable buildings is to pay
             such assessments or premiums on an earlier basis and Landlord shall
             pay the same on such basis, such assessments or premiums shall be
             included in Operating Expenses as paid by Landlord.

        (6)  REASONABLENESS. Landlord shall use its reasonable efforts to
             operate and maintain the Project in an economically reasonable
             manner.

                        8. INSURANCE AND INDEMNIFICATION

A. LANDLORD'S INSURANCE. All insurance maintained by Landlord shall be for the
sole benefit of Landlord and under Landlord's sole control.

        (1) PROPERTY INSURANCE. Landlord agrees to maintain property insurance
        insuring the Building against damage or destruction due to risk
        including fire, vandalism, and malicious mischief in an amount not less
        than the replacement cost thereof, in the form and with deductibles and
        endorsements as selected by Landlord. At its election, Landlord may
        instead (but shall have no obligation to) obtain "All Risk" coverage,
        and may also obtain earthquake, pollution, and/or flood insurance in
        amounts selected by Landlord.

        (2) OPTIONAL INSURANCE. Landlord, at Landlord's option, may also (but
        shall have no obligation to) carry insurance against loss of rent, in an
        amount equal to the amount of Base Rent and Additional Rent that
        Landlord could be required to abate to all Building tenants in the event
        of condemnation or casualty damage for a period of twelve (12) months.
        Landlord may also (but shall have no obligation to) carry such other
        insurance as Landlord may reasonably deem prudent or advisable,
        including, without limitation, liability insurance in such amounts and
        on such terms as Landlord shall determine. If and when Spieker
        Properties, L.P or its successor by merger or acquisition, is no longer
        the "Landlord" under this Lease, then at all times Landlord shall carry
        a policy of Commercial General Liability Insurance with limits of
        liability of no less than Three Million Dollars ($3,000,000.00).
        Landlord shall not be obligated to insure, and shall have no
        responsibility whatsoever for any damage to, any furniture, machinery,
        goods, inventory or supplies, or other personal property or fixtures
        which Tenant may keep or maintain in the Premises, or any leasehold
        improvements, additions or alterations within the Premises except where
        such damage arises from the ACTIVE negligence or willful misconduct of
        Landlord, its employees, agents, or contractors.

B. TENANT'S INSURANCE.

        So long as Franklin Resources, Inc. is "Tenant" under this Lease, the
        coverages Tenant is required to maintain under this Lease may be
        maintained under a program of Tenant's self-insurance or under policies
        that include self-insured retentions or deductibles that are typically
        carried by similarly situated tenants. Prior to any implementation of
        Tenant's self-insurance program, Tenant shall in writing advise Landlord
        of the self-insured retentions, or deductibles.

        (1) PROPERTY INSURANCE. Tenant shall procure at Tenant's sole cost and
        expense and keep in effect from the date of this Lease and at all times
        until the end of the Term, insurance on all personal property and
        fixtures of Tenant and all improvements, additions or alterations made
        by or for Tenant to the Premises on an "All Risk" basis, insuring such
        property for the full replacement value of such property.

        (2) LIABILITY INSURANCE. Tenant shall procure at Tenant's sole cost and
        expense and keep in effect from the date of this Lease and at all times
        until the end of the Term Commercial General Liability insurance
        covering bodily injury and property damage liability occurring in or
        about the Premises or arising out of the use and occupancy of the
        Premises and the Project, and any part of either, and any areas adjacent
        thereto, and the business operated by Tenant or by any other occupant of
        the Premises. Such insurance shall include contractual liability
        coverage insuring all of Tenant's indemnity obligations under this
        Lease. Such coverage shall have a minimum combined single limit of
        liability of at least Two Million Dollars ($2,000,000.00), and a minimum
        general aggregate limit of Three Million Dollars ($3,000,000.00), with
        an "Additional Insured - Managers or Lessors of Premises Endorsement"
        and the "Amendment of the Pollution Exclusion Endorsement." All such
        policies shall be written to apply to all bodily injury (including
        death), property damage or loss, personal and advertising injury and
        other covered loss, however occasioned, occurring during the policy
        term, shall be endorsed to add Landlord and any party holding an
        interest to which this Lease may be subordinated as an additional
        insured, and shall provide that such coverage shall be "PRIMARY" and
        non-contributing with any insurance maintained by Landlord, which shall
        be excess insurance only. Such coverage shall also contain endorsements
        including employees as additional insureds if not covered by Tenant's
        Commercial General Liability Insurance.

                                       9
<PAGE>   39

        All such insurance shall provide for the severability of interests of
        insureds; and shall be written on an "OCCURRENCE" basis, which shall
        afford coverage for all claims based on acts, omissions, injury and
        damage, which occurred or arose (or the onset of which occurred or
        arose) in whole or in part during the policy period.

        (3) WORKERS' COMPENSATION AND EMPLOYERS' LIABILITY INSURANCE. Tenant
        shall carry Workers' Compensation Insurance as required by any
        Regulation, throughout the Term at Tenant's sole cost and expense. To
        the extent required by any Regulation, Tenant shall also carry
        Employers' Liability Insurance in amounts not less than One Million
        Dollars ($1,000,000) each accident for bodily injury by accident; One
        Million Dollars ($1,000,000) policy limit for bodily injury by disease;
        and One Million Dollars ($1,000,000) each employee for bodily injury by
        disease, throughout the Term at Tenant's sole cost and expense.

        (4) COMMERCIAL AUTO LIABILITY INSURANCE. Tenant shall procure at
        Tenant's sole cost and expense and keep in effect from the date of this
        Lease and at all times until the end of the Term commercial auto
        liability insurance with a combined limit of not less than One Million
        Dollars ($1,000,000) for bodily injury and property damage for each
        accident. Such insurance shall cover liability relating to any auto
        (including owned, hired and non-owned autos).

        (5) GENERAL INSURANCE REQUIREMENTS. All coverages described in this
        Paragraph 8.B. shall be endorsed to (i) provide Landlord with thirty
        (30) days' notice of cancellation or material change in terms; and (ii)
        waive all rights of subrogation by the insurance carrier against
        Landlord. If at any time during the Term the amount or coverage of
        insurance which Tenant is required to carry under this Paragraph 8.B.
        is, in Landlord's reasonable judgment, materially less than the amount
        or type of insurance coverage typically carried by owners or tenants of
        properties located in the general area in which the Premises are located
        which are similar to and operated for similar purposes as the Premises
        or if Tenant's use of the Premises should change with or without
        Landlord's consent, Landlord shall have the right to require Tenant to
        increase the amount or change the types of insurance coverage required
        under this Paragraph 8.B. All insurance policies required to be carried
        by Tenant under this Lease shall be written by companies rated A VII or
        better in "Best's Insurance Guide" and authorized to do business in the
        State of California. Should Franklin Resources, Inc. or its successor by
        merger or acquisition, no longer be "Tenant" under this Lease, then
        deductible amounts under all insurance policies required to be carried
        by Tenant under this Lease shall not exceed Five Thousand Dollars
        ($5,000.00) per occurrence. Tenant shall deliver to Landlord on or
        before the Term Commencement Date, and thereafter at least thirty (30)
        days before the expiration dates of the expired policies, or a
        certificate evidencing the same issued by the insurer thereunder; and,
        if Tenant shall fail to procure such insurance, or to deliver such
        certificates, Landlord may, at Landlord's option and in addition to
        Landlord's other remedies in the event of a default by Tenant hereunder,
        procure the same for the account of Tenant, and the cost thereof shall
        be paid to Landlord as Additional Rent.

C. INDEMNIFICATION. Tenant shall indemnify, defend by counsel reasonably
acceptable to Landlord, protect and hold Landlord harmless from and against any
and all claims, liabilities, losses, costs, loss of rents, liens, damages,
injuries or expenses, including reasonable attorneys' and consultants' fees and
court costs, demands, causes of action, or judgments, directly or indirectly
arising out of or related to: (1) claims of injury to or death of persons or
damage to property occurring or resulting directly or indirectly from the use or
occupancy of the Premises, Building or Project by Tenant or Tenant's Parties, or
from activities or failures to act of Tenant or Tenant's Parties; (2) claims
arising from work or labor performed, or for materials or supplies furnished to
or at the request of Tenant in connection with performance of any work done for
the account of Tenant within the Premises or Project; (3) claims arising from
any breach or default on the part of Tenant in the performance of any covenant
contained in this Lease; and (4) claims arising from the negligence or
intentional acts or omissions of Tenant or Tenant's Parties. The foregoing
indemnity by Tenant shall not be applicable to claims to the extent arising from
the active negligence or willful misconduct of Landlord. Landlord shall not be
liable to Tenant and Tenant hereby waives all claims against Landlord for any
injury or damage to any person or property in or about the Premises, Building or
Project by or from any cause whatsoever (other than Landlord's active negligence
or willful misconduct) and, without limiting the generality of the foregoing,
whether caused by water leakage of any character from the roof, walls, basement
or other portion of the Premises, Building or Project, or caused by gas, fire,
oil or electricity in, on or about the Premises, Building or Project. Landlord
shall indemnify, defend by counsel reasonably acceptable to Tenant, protect and
hold Tenant harmless from and against any and all claims, liabilities, losses,
costs, liens, damages, injuries or expenses, including reasonable attorneys'
fees and consultants' fees and court costs, demands, causes of action or
judgments directly or indirectly arising from the active negligence or willful
misconduct of Landlord or its employees, agents or contractors. The provisions
of this Paragraph shall survive the expiration or earlier termination of this
Lease.

                            9. WAIVER OF SUBROGATION

    To the extent permitted by law and without affecting the coverage provided
by insurance to be maintained hereunder or any other rights or remedies,
Landlord and Tenant each waive any right to recover against the other for: (a)
damages for injury to or death of persons; (b) damages to property, including
personal property; (c) damages to the Premises or any part thereof; and (d)
claims arising by reason of the foregoing due to hazards covered by insurance
maintained or required to be maintained pursuant to this Lease to the extent of
proceeds recovered therefrom, or proceeds which would have been recoverable
therefrom in the case of the failure of any party to maintain any insurance
coverage required to be maintained by such party pursuant to this Lease. This
provision is intended to waive fully, any rights and/or claims arising by reason
of the foregoing, but only to the extent that any of the foregoing damages
and/or claims referred to above are covered or would be covered, and only to the
extent of such coverage, by insurance actually carried or required to be
maintained pursuant to this Lease by either Landlord or Tenant. This provision
is also intended to waive fully, and for the benefit of each party, any rights
and/or claims which might give rise to a right of subrogation on any insurance
carrier. Subject to all qualifications of this Paragraph 9, Landlord waives its
rights as specified in this Paragraph 9 with respect to any subtenant that it
has approved pursuant to Paragraph 21 but only in exchange for the written
waiver of such rights to be given by such subtenant to Landlord upon such
subtenant taking possession of the Premises or a portion thereof. Each party
shall cause each insurance policy obtained by it to provide that the insurance
company waives all right of recovery by way of subrogation against either party
in connection with any damage covered by any policy.

                     10. LANDLORD'S REPAIRS AND MAINTENANCE

    Landlord shall at Landlord's expense maintain in first-class condition and
repair, reasonable wear and tear excepted, the structural soundness of the roof,
foundations, and exterior walls of the Building. The term "exterior walls" as
used herein shall not include windows, glass or plate glass, doors, dock bumpers
or dock plates, special store fronts or office entries. Landlord shall perform
on behalf of Tenant and other tenants of the Project the maintenance of the
public and common areas of the Project including, but not limited to, the
landscaped areas, parking areas, driveways, sanitary and storm sewer lines,
utilities services, HVAC systems, electric equipment (excluding Tenant's
emergency electric generator(s) described in Paragraph 38 H. hereof) servicing
the Building, exterior lighting, Project trash removal services, and anything
which affects the operation and exterior appearance of the Project, which
determination shall be at Landlord's reasonable discretion. Any damage caused by
or repairs necessitated by any negligence or act of Tenant or Tenant's Parties
may be repaired by Landlord at Landlord's option and Tenant's expense. Tenant
shall immediately give Landlord written notice of any defect or need of repairs
in such components of the Building for which Landlord is responsible, after
which Landlord shall have a reasonable opportunity and the right to enter the
Premises at all reasonable times to repair same. Landlord's liability with
respect to any defects, repairs, or maintenance for which Landlord is
responsible under any of the provisions of this Lease shall be limited to the
cost of such repairs or maintenance, and there shall be no abatement of rent and
no liability of Landlord by reason of any injury to or interference with
Tenant's business arising from the making of repairs, alterations or
improvements in or to any portion of the Premises, the Building or the

                                       10
<PAGE>   40

Project or to fixtures, appurtenances or equipment in the Building, except as
provided in Paragraph 24 or anywhere else in this Lease. By taking possession of
the Premises, Tenant, subject to Paragraph 2.B. of this Lease, accepts them "as
is," as being in good order, condition and repair and the condition in which
Landlord is obligated to deliver them and suitable for the Permitted Use and
Tenant's intended operations in the Premises, whether or not any notice of
acceptance is given.

                      11. TENANT'S REPAIRS AND MAINTENANCE

    Tenant shall at all times during the Term at Tenant's expense maintain all
interior non-structural parts of the Premises and such portions of the Building
as are within the exclusive control of Tenant in a first-class, good, clean and
secure condition and promptly make all necessary repairs and replacements, as
reasonably determined by Landlord, including but not limited to, all windows,
glass, doors, walls, including demising walls, and wall finishes, floors and
floor covering, ceiling insulation, truck doors, hardware, plumbing work and
fixtures, downspouts, entries, skylights, smoke hatches, roof vents, electrical
and lighting systems, and fire sprinklers, and the emergency generator(s)
described in Paragraph 38.H. of this Lease, with materials and workmanship of
the same character, kind and quality as the original. Tenant shall at Tenant's
expense also perform regular removal of trash and debris. Notwithstanding
anything to the contrary contained herein, Tenant shall, at its expense,
promptly repair any damage to the Premises or the Building or Project resulting
from or caused by any negligence or act of Tenant or Tenant's Parties. Nothing
herein shall expressly or by implication render Tenant Landlord's agent or
contractor to effect any repairs or maintenance required of Tenant under this
Paragraph 11, as to all of which Tenant shall be solely responsible.

                                 12. ALTERATIONS

A. Except for interior, nonstructural alterations costing less than Twenty-five
Thousand Dollars ($25,000.00) to perform, Tenant shall not make, or allow to be
made, any alterations, physical additions, improvements or partitions, in, about
or to the Premises ("ALTERATIONS") without obtaining the prior written consent
of Landlord, which consent shall not be unreasonably withheld, delayed or
conditioned with respect to proposed Alterations which: (a) comply with all
applicable Regulations; (b) are, in Landlord's opinion, compatible with the
Building or the Project and its mechanical, plumbing, electrical,
heating/ventilation/air conditioning systems, and will not cause the Building or
Project or such systems to be required to be modified to comply with any
Regulations (including, without limitation, the Americans With Disabilities Act)
unless Tenant agrees to perform the same at its sole cost and expense; and (c)
will not interfere with the use and occupancy of any other portion of the
Project by any other tenant or its invitees. Specifically, but without limiting
the generality of the foregoing, Landlord shall have the right of written
consent (which consent shall not be unreasonably withheld, delayed or
conditioned) for all plans and specifications for the proposed Alterations,
construction means and methods, all appropriate permits and licenses, any
contractor or subcontractor to be employed on the work of Alterations, and the
time for performance of such work, and may impose reasonable rules and
regulations for contractors and subcontractors performing such work. Tenant
shall also supply to Landlord any documents and information reasonably requested
by Landlord in connection with Landlord's consideration of a request for
approval hereunder. Tenant shall cause all Alterations to be accomplished in a
first-class, good and workmanlike manner, and to comply with all applicable
Regulations and Paragraph 27 hereof. If Landlord does not respond in writing
within ten (10) days of receipt of Tenant's plan, stating with specificity its
reasons therefor, Tenant shall deliver a second notice to Landlord, stating in
bold type on the first page thereof "URGENT - DELAY NOTICE," which notice may be
delivered by facsimile to Landlord at Landlord's Notice Address and as otherwise
set forth in Paragraph 32, and if Landlord fails to respond within five (5) days
thereafter, Landlord's consent shall be deemed given. Tenant shall at Tenant's
sole expense, perform any additional work required under applicable Regulations
due to the Alterations hereunder. No review or consent by Landlord of or to any
proposed Alteration or additional work shall constitute a waiver of Tenant's
obligations under this Paragraph 12. Tenant shall reimburse Landlord for all
third-party costs which Landlord may reasonably and actually incur in connection
with granting approval to Tenant for any such Alterations, including any costs
or expenses which Landlord may incur in electing to have outside architects and
engineers review said plans and specifications, to the extent it is reasonably
necessary to do so. All such Alterations shall remain the property of Tenant
until the expiration or earlier termination of this Lease, at which time they
shall be and become the property of Landlord; provided, however, that Landlord
may, at Landlord's option, require that Tenant, at Tenant's expense, remove any
or all Alterations made by Tenant which Landlord indicated at the time consent
thereto was granted would have to be removed and restore the Premises by the
expiration or earlier termination of this Lease, to their condition existing
prior to the construction of any such Alterations. All such removals and
restoration shall be accomplished in a first-class and good and workmanlike
manner so as not to cause any damage to the Premises or Project whatsoever. If
Tenant fails to remove such Alterations or Tenant's trade fixtures or furniture
or other personal property, Landlord may keep and use them or remove any of them
and cause them to be stored or sold in accordance with applicable law, at
Tenant's sole expense. In addition to and wholly apart from Tenant's obligation
to pay Tenant's Proportionate Share of Operating Expenses, Tenant shall be
responsible for and shall pay prior to delinquency any taxes or governmental
service fees, possessory interest taxes, fees or charges in lieu of any such
taxes, capital levies, or other charges imposed upon, levied with respect to or
assessed against its fixtures or personal property, on the value of Alterations
within the Premises, and on Tenant's interest pursuant to this Lease, or any
increase in any of the foregoing based on such Alterations. To the extent that
any such taxes are not separately assessed or billed to Tenant, Tenant shall pay
the amount thereof as invoiced to Tenant by Landlord.

        The work necessary to make such Alterations shall be performed by
employees, contractors or space planners employed by Landlord or, with
Landlord's prior written consent, which consent shall not be unreasonably
withheld, delayed or conditioned, by space planners and/or contractors licensed
in California which are employed by Tenant. In addition, if Landlord elected at
the time consent to any such Alterations was granted to require that any such
Alterations be removed by Tenant upon the expiration or earlier termination of
the Term, and Landlord elects to be responsible for performing such removal,
then notwithstanding the provisions of the preceding paragraph, Tenant shall pay
to Landlord the cost of removing any such Alterations and restoring the Premises
to their original condition such cost to include a reasonable charge for
Landlord's overhead and profit as provided above, and such amount may be
deducted from the Security Deposit or any other sums or amounts held by Landlord
under this Lease.

B. In compliance with Paragraph 27 hereof, at least ten (10) business days
before beginning construction of any Alteration, Tenant shall give Landlord
written notice of the expected commencement date of that construction to permit
Landlord to post and record a notice of non-responsibility. Upon substantial
completion of construction, if the law so provides, Tenant shall cause a timely
notice of completion to be recorded in the office of the recorder of the county
in which the Building is located.

                                    13. SIGNS

Tenant shall not place, install, affix, paint or maintain any signs, notices,
graphics or banners whatsoever or any window decor which is visible in or from
public view or corridors, the common areas or the exterior of the Premises or
the Building, in or on any exterior window or window fronting upon any common
areas or service area or upon any truck doors or man doors without Landlord's
prior written approval which Landlord shall have the right to withhold in its
absolute and sole discretion; provided that Tenant's name shall be included in
any Building-standard door and directory signage, if any, and Tenant shall have
the right to install at Tenant's sole cost, expense and responsibility,
identifying signage on the existing monument sign at the entranceway to the
Project, in accordance with Landlord's Building signage criteria attached as
EXHIBIT F hereto, including without limitation, payment by Tenant of any fee
charged by Landlord for maintaining such signage, which fee shall constitute
Additional Rent hereunder. Any installation of signs, notices, graphics or
banners on or about the Premises or Project approved by Landlord shall be
subject to any Regulations and to any other requirements imposed by Landlord.
Tenant shall remove all such signs or graphics by the expiration or any earlier
termination of this Lease. Such installations and removals shall be made in such
manner as to avoid injury to or defacement of the Premises, Building or Project
and any other improvements contained therein, and Tenant shall repair any injury
or defacement including without limitation discoloration caused by such
installation or removal.

                         14. INSPECTION/POSTING NOTICES

After reasonable notice and subject to such security requirements as Tenant may
reasonably impose, except in emergencies where no such notice or COMPLIANCE WITH
ANY SUCH security requirements shall be required, Landlord and Landlord's agents
and representatives, shall have the right to enter the Premises to inspect the
same, to clean, to perform such work as may be permitted or required hereunder,
to make repairs, improvements or alterations to the Premises, Building or
Project or to other tenant spaces therein, to deal with emergencies, to post
such notices as may be permitted or required by law to prevent the perfection of
liens against Landlord's interest in the Project or to exhibit the Premises to
prospective tenants (during the last twelve (12) months of the Term or extended
Term), purchasers, encumbrancers or to others, or for any other purpose as
Landlord may deem necessary or desirable; provided, however, that Landlord shall
use reasonable efforts not to unreasonably interfere with Tenant's business
operations. Tenant shall have the right to require a representative of Tenant to
accompany Landlord during any such entry or inspection. Tenant shall not be
entitled to any abatement of Rent by reason of the exercise of any such right of
entry. Tenant waives any claim for damages for any injury or inconvenience to or
interference with Tenant's business, any loss of occupancy or quiet enjoyment of
the Premises, and any other loss occasioned thereby except for any damage to
persons as properly caused by the active negligence or willful misconduct of
Landlord or its employees, agents or contractors. Landlord shall at all times
have and retain a key with which to unlock all of the doors in, upon and about
the Premises, excluding Tenant's vaults and safes or special security areas
(designated in advance), and Landlord shall have the right to use any and all
means which Landlord may deem necessary or proper to open said doors in an
emergency, in order to obtain entry to any portion of the Premises, and any
entry to the Premises or portions thereof obtained by Landlord by any of said
means, or otherwise, shall not be construed 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 portions thereof. At any time within six (6)
months prior to the expiration of the Term or following any earlier termination
of this Lease or agreement to terminate this Lease, Landlord shall have the
right to erect on the Premises, Building and/or Project a suitable sign
indicating that the Premises are available for lease.

                           15. SERVICES AND UTILITIES

A. Tenant shall pay directly for all water, gas, heat, air conditioning, light,
power, telephone, sewer, sprinkler charges and other utilities and services used
on or from the Premises, together with any taxes, penalties, surcharges or the
like pertaining thereto, and maintenance charges for utilities and shall furnish
all electric light bulbs, ballasts and tubes. Notwithstanding anything in this
Lease to the contrary, Tenant shall have the right to conduct its business
operations within the Premises, and to receive reasonable quantities of water,
electricity and HVAC in connection therewith, seven (7) days per week,
twenty-four (24) hours per day. If any such services are not separately billed
or metered to Tenant, Tenant shall pay a proportion, as determined by Landlord,
of all charges jointly serving other premises. All sums payable under this
Paragraph 15 shall constitute Additional Rent hereunder. Landlord shall use
reasonable efforts to reasonably capture any material benefit available through
deregulation of electricity supply or of the supply of other utilities.

B. Tenant acknowledges that Tenant has inspected and accepts the water,
electricity, heat and air conditioning and other utilities and services being
supplied or furnished to the Premises as of the date Tenant takes possession of
the Premises, if any, as being sufficient in their present condition, "as is,"
for the Permitted Use, and for Tenant's intended operations in the Premises.

C. Tenant shall not without written consent of Landlord (which consent shall not
be unreasonably withheld, delayed or conditioned) use any apparatus, equipment
or device in the Premises, including without limitation, computers, electronic
data processing machines, copying machines, and other machines, using excess
lighting or using electric current, water, or any other resource in excess of or
which will in any way increase the amount of electricity, water, or any other
resource being furnished or supplied for the use of the Premises for reasonable
and normal office use, in each case as of the date Tenant takes possession of
the Premises as reasonably determined by Landlord, or which will require
additions or alterations to or interfere with the Building power distribution
systems; nor connect with electric current, except through existing electrical
outlets in the Premises or water pipes, any apparatus, equipment or device for
the purpose of using electrical current, water, or any other resource. If Tenant
shall require water or electric current or any other resource in excess of that
being furnished or supplied for the use of the Premises as of the date Tenant
takes possession of the Premises, if any, as reasonably determined by Landlord,
Tenant shall first procure the written consent of Landlord (which consent shall
not be unreasonably withheld, delayed or conditioned), to the use thereof, and
Landlord may cause a special meter to be installed in the Premises so as to
measure the amount of water, electric current or other resource consumed for any
such other use. Tenant shall pay directly to Landlord as an addition to and
separate from payment of Operating Expenses the cost of all such additional
resources, energy, utility service and meters (and of installation, maintenance
and repair thereof and of any additional circuits or other equipment necessary
to furnish such additional resources, energy, utility or service). Landlord may
add to the separate or metered charge a recovery of additional expense incurred
in keeping account of the excess water, electric current or other resource so
consumed. Landlord shall not be liable for any damages directly or indirectly
resulting from nor shall the Rent or any monies owed Landlord under this Lease
herein reserved be abated by reason of: (a) the installation, use or
interruption of use of any equipment used in connection with the furnishing of
any such utilities or services, or any change in the character or means of
supplying or providing any such utilities or services or any supplier thereof;
(b) the failure to furnish or delay in furnishing any such utilities or services
when such failure or delay is caused by acts of God or the elements, labor
disturbances of any character, or any other accidents or other conditions beyond
the reasonable control of Landlord or because of any interruption of service due
to Tenant's use of water, electric current or other resource in excess of that
being supplied or furnished for the use of the Premises as of

                                       12
<PAGE>   42
the date Tenant takes possession of the Premises; or (c) the inadequacy,
limitation, curtailment, rationing or restriction on use of water, electricity,
gas or any other form of energy or any other service or utility whatsoever
serving the Premises or Project otherwise; or (d) the partial or total
unavailability of any such utilities or services to the Premises or the
Building, whether by Regulation or otherwise; nor shall any such occurrence
constitute an actual or constructive eviction of Tenant. Landlord shall further
have no obligation to protect or preserve any apparatus, equipment or device
installed by Tenant in the Premises. In addition, Landlord reserves the right to
change the supplier or provider of any such utility or service from time to
time. Landlord may, but shall not be obligated to, upon notice to Tenant,
contract with or otherwise obtain any electrical or other such service for or
with respect to the Premises or Tenant's operations therein from any supplier or
provider of any such service. Tenant shall cooperate with Landlord and any
supplier or provider of such services designated by Landlord from time to time
to facilitate the delivery of such services to Tenant at the Premises and to the
Building and Project, including without limitation allowing Landlord and
Landlord's suppliers or providers, and their respective agents and contractors,
reasonable access to the Premises for the purpose of installing, maintaining,
repairing, replacing or upgrading such service or any equipment or machinery
associated therewith.

    Subject to Paragraph 35 of this Lease, for services or utilities that
    Landlord is required to supply to the Premises hereunder, but is actively
    negligent in adequately providing or altogether fails to provide, Tenant's
    Rent shall be abated or reduced for such period of time that the Premises or
    portion thereof is not supplied with such services or utilities, in
    proportion to the rentable square feet of the Premises that is so affected
    bears to the total rentable square feet of the Premises.

D. Landlord acknowledges and agrees to Tenant's exclusive use, operation,
maintenance, repair and security protection of those certain underground
conduit, vault and equipment facilities within the Project for Tenant's
telecommunication cabling and equipment. Furthermore, Tenant agrees TO and
accepts complete and full responsibility and control of the facilities described
in the preceding sentence.

                                16. SUBORDINATION

Without the necessity of any additional document being executed by Tenant for
the purpose of effecting a subordination, the Lease shall be and is hereby
declared to be subject and subordinate at all times to: (a) all ground leases or
underlying leases which may hereafter be executed affecting the Premises and/or
the land upon which the Premises and Project are situated, or both; and (b) any
mortgage or deed of trust which may be placed upon the Building, the Project
and/or the land upon which the Premises or the Project are situated, or said
ground leases or underlying leases, or Landlord's interest or estate in any of
said items which is specified as security. Notwithstanding the foregoing,
Landlord shall have the right to subordinate or cause to be subordinated any
such ground leases or underlying leases or any such liens to this Lease. If any
ground lease or underlying lease terminates for any reason or any mortgage or
deed of trust is foreclosed or a conveyance in lieu of foreclosure is made for
any reason, Tenant shall, notwithstanding any subordination, attorn to and
become the Tenant of the successor in interest to Landlord provided that Tenant
shall not be disturbed in its possession under this Lease by such successor in
interest so long as Tenant is not in default under this Lease beyond the
expiration of all applicable grace, notice and cure periods. Within ten (10)
days after request by Landlord, Tenant shall execute and deliver any
commercially reasonable additional documents evidencing Tenant's attornment or
the subordination of this Lease with respect to any such ground leases or
underlying leases or any such mortgage or deed of trust, in the form reasonably
requested by Landlord or by any ground landlord, mortgagee, or beneficiary under
a deed of trust, subject to such nondisturbance requirement.

                            17. FINANCIAL STATEMENTS

At the request of Landlord from time to time, Tenant shall provide to Landlord
Tenant's and any guarantor's current financial statements or other information
discussing financial worth of Tenant and any guarantor, which Landlord shall use
solely for purposes of this Lease and in connection with the ownership,
management, financing and disposition of the Project.

                            18. ESTOPPEL CERTIFICATE

Tenant agrees from time to time, but not more than twice in any calendar year,
within ten (10) business days after request of Landlord, to deliver to Landlord,
or Landlord's designee, an estoppel certificate stating that this Lease is in
full force and effect, that this Lease has not been modified (or stating all
modifications, written or oral, to this Lease), the date to which Rent has been
paid, the unexpired portion of this Lease, that there are no current defaults by
Landlord or Tenant under this Lease (or specifying any such defaults), that the
leasehold estate granted by this Lease is the sole interest of Tenant in the
Premises and/or the land at which the Premises are situated (subject to such
rights of first refusal and/or options to purchase as may be set forth herein),
and such other matters pertaining to this Lease as may be reasonably requested
by Landlord or any mortgagee, beneficiary, purchaser or prospective purchaser of
the Building or Project or any interest therein. If Tenant fails to execute such
certificate within such ten (10) business day period, and such failure continues
for more than five (5) days following delivery of a second request therefor,
which second notice shall be labeled at the top in bold letters "URGENT - DELAY
NOTICE," then the failure by Tenant to execute and deliver such certificate
shall constitute A DEFAULT UNDER THIS LEASE. Tenant agrees that if Tenant fails
to execute and deliver such certificate within second five (5) day period,
Landlord may execute and deliver such certificate on Tenant's behalf and that
such certificate shall be binding on Tenant. Landlord and Tenant intend that any
statement delivered pursuant to this Paragraph may be relied upon by any
mortgagee, beneficiary, purchaser or prospective purchaser of the Building or
Project or any interest therein.

                              19. SECURITY DEPOSIT

In the event Tenant does not exercise its first and/or second option to extend
the Term pursuant to Paragraph 38.B. of this Lease, Tenant agrees to deposit
with Landlord no later than twelve (12) months prior to the expiration of the
Term, or the extended Term, a security deposit as stated in the Basic Lease
Information (the "SECURITY DEPOSIT"), which sum shall be held and owned by
Landlord, without obligation to pay interest, as security for the performance of
Tenant's covenants and obligations under this Lease. The Security Deposit is not
an advance rental deposit or a measure of damages incurred by Landlord in case
of Tenant's default. Upon the occurrence of any event of default by Tenant,
Landlord may from time to time, without prejudice to any other remedy provided
herein or by law, use such fund as a credit to the extent necessary to credit
against any arrears of Rent or other payments due to Landlord hereunder, and any
other damage, injury, expense or liability caused by such event of default, and
Tenant shall pay to Landlord, on demand, the amount so applied in order to
restore the Security Deposit to its original amount. Although the Security
Deposit shall be deemed the

                                       13
<PAGE>   43

property of Landlord, any remaining balance of such deposit shall be returned by
Landlord to Tenant at such time after termination of this Lease that all of
Tenant's obligations under this Lease have been fulfilled, reduced by such
amounts as may be required by Landlord to remedy defaults on the part of Tenant
in the payment of Rent or other obligations of Tenant under this Lease, to
repair damage to the Premises, Building or Project caused by Tenant or any
Tenant's Parties and to clean the Premises. Landlord may use and commingle the
Security Deposit with other funds of Landlord.

                       20. LIMITATION OF TENANT'S REMEDIES

The obligations and liability of Landlord to Tenant for any default by Landlord
under the terms of this Lease are not personal obligations of Landlord or of the
individual or other partners of Landlord or its or their partners, directors,
officers, or shareholders, and Tenant agrees to look solely to Landlord's
interest in the Project (including the rents, issues and proceeds therefrom) for
the recovery of any amount from Landlord, and shall not look to other assets of
Landlord nor seek recourse against the assets of the individual or other
partners of Landlord or its or their partners, directors, officers or
shareholders. Any lien obtained to enforce any such judgment and any levy of
execution thereon shall be subject and subordinate to any lien, mortgage or deed
of trust on the Project. Under no circumstances shall Tenant have the right to
offset against or recoup Rent or other payments due and to become due to
Landlord hereunder except as expressly provided in Paragraph 23.B. below or
elsewhere in this Lease, which Rent and other payments shall be absolutely due
and payable hereunder in accordance with the terms hereof.

                          21. ASSIGNMENT AND SUBLETTING

A.  (1) GENERAL. Tenant shall not assign or pledge this Lease or sublet the
    Premises or any part thereof, whether voluntarily or by operation of law, or
    permit the use or occupancy of the Premises or any part thereof by anyone
    other than Tenant, or suffer or permit any such assignment, pledge,
    subleasing or occupancy, without Landlord's prior written consent except as
    provided herein which consent shall not be unreasonably withheld, delayed or
    conditioned. If Tenant desires to assign this Lease or sublet any or all of
    the Premises, Tenant shall give Landlord written notice (the "TRANSFER
    NOTICE") at least thirty (30) days prior to the anticipated effective date
    of the proposed assignment or sublease, which shall contain all of the
    information reasonably requested by Landlord to address Landlord's decision
    criteria specified hereinafter. Landlord shall then have a period of fifteen
    (15) business days following receipt of the Transfer Notice to notify Tenant
    in writing whether Landlord consents to the proposed assignment or sublease,
    subject, however, to Landlord's prior written consent of the proposed
    assignee or subtenant and of any related documents or agreements associated
    with the assignment or sublease and if Landlord withholds such consent,
    stating with specificity the reasons therefor. Consent to any assignment or
    subletting shall not constitute consent to any subsequent transaction to
    which this Paragraph 21 applies.

    (2) CONDITIONS OF LANDLORD'S CONSENT. Without limiting the other instances
    in which it may be reasonable for Landlord to withhold Landlord's consent to
    an assignment or subletting, Landlord and Tenant acknowledge that it shall
    be reasonable for Landlord to withhold Landlord's consent in the following
    instances: if the proposed assignee does not agree to be bound by and assume
    the obligations of Tenant under this Lease in form and substance reasonably
    satisfactory to Landlord; the use of the Premises by such proposed assignee
    or subtenant would not be a Permitted Use or would violate any exclusivity
    or other arrangement which Landlord has with any other tenant or occupant or
    any Regulation or would increase the Occupancy Density or Parking Density of
    the Building or Project, as reasonably determined by Landlord; the proposed
    assignee or subtenant is not of sound financial condition as determined by
    Landlord in Landlord's reasonable discretion; the proposed assignee or
    subtenant is a governmental agency that occupies more than twenty-five
    percent (25%) of the Premises; the proposed assignee or subtenant does not
    have a good reputation as a tenant of property or a good business
    reputation; the proposed assignee or subtenant is a person with whom
    Landlord is negotiating to lease space in the Project or is a present tenant
    of the Project; the assignment or subletting would entail any Alterations
    which would lessen the value of the leasehold improvements in the Premises
    or use of any Hazardous Materials or other noxious use or use which may
    disturb other tenants of the Project; or Tenant is in default of any
    obligation of Tenant under this Lease, or Tenant has defaulted under this
    Lease on three (3) or more occasions during any twelve (12) months preceding
    the date that Tenant shall request consent. Failure by or refusal of
    Landlord to consent to a proposed assignee or subtenant shall not cause a
    termination of this Lease. At the option of Landlord, a surrender and
    termination of this Lease shall operate as an assignment to Landlord of some
    or all subleases or subtenancies. Landlord shall exercise this option by
    giving notice of that assignment to such subtenants on or before the
    effective date of the surrender and termination. In connection with each
    request for assignment or subletting, Tenant shall pay to Landlord
    Landlord's standard fee for approving such requests, as well as all costs
    incurred by Landlord or any mortgagee or ground lessor in approving each
    such request and effecting any such transfer, including, without limitation,
    reasonable attorneys' fees in an amount not to exceed Twenty-five Hundred
    Dollars ($2,500.00).

B. BONUS RENT. For any subleasing or assignment that is in the aggregate less
than twenty-five percent (25%) of the Premises, any Rent or other consideration
realized by Tenant under any such sublease or assignment, in excess of the Rent
payable hereunder, after amortization of all transaction costs reasonably
incurred in connection therewith, including but not limited to reasonable
brokerage commission incurred by Tenant, legal fees, costs of improvements,
shall be divided and paid, fifty percent (50%) to Tenant, fifty percent (50%) to
Landlord ("BONUS RENT"). However, for any subleasing or assignment that is in
the aggregate twenty-five percent (25%) or more of the Premises, then the Bonus
Rent shall be divided and paid twenty-five percent (25%) to Tenant and
seventy-five (75%) to Landlord. In any subletting or assignment undertaken by
Tenant, Tenant shall diligently seek to obtain the maximum rental amount
available in the marketplace for comparable space available for primary leasing.

C. CORPORATION. If Tenant is a corporation, a transfer of corporate shares by
sale, assignment, bequest, inheritance, operation of law or other disposition
(including such a transfer to or by a receiver or trustee in federal or state
bankruptcy, insolvency or other proceedings) resulting in a change in the
present control of such corporation or any of its parent corporations by the
person or persons owning a majority of said corporate shares, shall constitute
an assignment for purposes of this Lease. So long as Franklin Resources, Inc.,
is the "Tenant" in possession of the Premises, and Tenant is not in default of
this Lease after the expiration of all applicable grace, notice and cure
periods, Tenant shall have the right subject to the terms and conditions
hereinafter set forth, without the consent of Landlord, to (a) assign its
interest in this Lease (i) to any corporation which is a successor to Tenant
either by merger or consolidation, or (ii) to a purchaser of all or
substantially all of Tenant's assets (provided such purchaser shall have also
assumed substantially all of Tenant's liabilities), or to a corporation or other
entity which shall control, be under the control of, or be under common control
with, Franklin Resources, Inc., (the term "control" as used herein shall be
deemed to mean ownership of more than fifty percent (50%) of the outstanding
voting stock of a corporation, or other majority equity and controlling interest
if Tenant is not a corporation) (any such entity being a "Related Entity"), or

                                       14
<PAGE>   44

(b) sublease all or any portion of the Premises to a Related Entity; upon the
condition that (i) the principal purpose of such assignment or sublease is not
the acquisition of Tenant's interest in this Lease (except if such assignment or
sublease is made to a Related Entity and is made for a valid intra-corporate
business purpose and is not made to circumvent the provisions of this Paragraph
21), and (ii) any such assignee shall have a net worth and annual income and
cash flow, determined in accordance with generally accepted accounting
principles, consistently applied, after giving effect to such assignment, in
amounts necessary to perform its duties, obligations and liabilities hereunder,
as reasonably determined by Landlord. Tenant shall, within ten (10) business
days after execution thereof, deliver to Landlord (a) a duplicate original
instrument of assignment, in form and substance reasonably satisfactory to
Landlord, duly executed by Tenant, (b) an instrument in form and substance
reasonably satisfactory to Landlord, duly executed by the assignee, in which
such assignee shall assume observance and performance of, and agree to be
personally bound by all of the terms, covenants and conditions of this Lease on
Tenant's part to be observed and performed, or (c) a duplicate original sublease
in form and substance reasonably satisfactory to Landlord, duly executed by
Tenant and subtenant, in which such assignee shall assume observance and
performance of, and agree to be personally bound by all of the terms, covenants
and conditions of this Lease on Tenant's part to be observed and performed.

D. UNINCORPORATED ENTITY. If Tenant is a partnership, joint venture,
unincorporated limited liability company or other unincorporated business form,
a transfer of the interest of persons, firms or entities responsible for
managerial control of Tenant by sale, assignment, bequest, inheritance,
operation of law or other disposition, so as to result in a change in the
present control of said entity and/or of the underlying beneficial interests of
said entity and/or a change in the identity of the persons responsible for the
general credit obligations of said entity shall constitute an assignment for all
purposes of this Lease.

E. LIABILITY. No assignment or subletting by Tenant, permitted or otherwise,
shall relieve Tenant of any obligation under this Lease or alter the primary
liability of the Tenant named herein for the payment of Rent or for the
performance of any other obligations to be performed by Tenant, including
obligations contained in Paragraph 25 with respect to any assignee or subtenant.
Landlord may collect rent or other amounts or any portion thereof from any
assignee, subtenant, or other occupant of the Premises, permitted or otherwise,
and apply the net rent collected to the Rent payable hereunder, but no such
collection shall be deemed to be a waiver of this Paragraph 21, or the
acceptance of the assignee, subtenant or occupant as tenant, or a release of
Tenant from the further performance by Tenant of the obligations of Tenant under
this Lease. Any assignment or subletting which conflicts with the provisions
hereof shall be void.

                                  22. AUTHORITY

Landlord represents and warrants that it has full right and authority to enter
into this Lease and to perform all of Landlord's obligations hereunder and that
all persons signing this Lease on its behalf are authorized to do. Tenant and
the person or persons, if any, signing on behalf of Tenant, jointly and
severally represent and warrant that Tenant has full right and authority to
enter into this Lease, and to perform all of Tenant's obligations hereunder, and
that all persons signing this Lease on its behalf are authorized to do so.

                                23. CONDEMNATION

A. CONDEMNATION RESULTING IN TERMINATION. If the whole or any substantial part
of the Premises should be taken or condemned for any public use under any
Regulation, or by right of eminent domain, or by private purchase in lieu
thereof, and the taking would prevent or materially interfere with the Permitted
Use of the Premises, either party shall have the right to terminate this Lease
at its option. If any material portion of the Building or Project is taken or
condemned for any public use under any Regulation, or by right of eminent
domain, or by private purchase in lieu thereof, Landlord may terminate this
Lease at its option. In either of such events, the Rent shall be abated during
the unexpired portion of this Lease, effective when the physical taking of said
Premises shall have occurred.

B. CONDEMNATION NOT RESULTING IN TERMINATION. If a portion of the Project of
which the Premises are a part should be taken or condemned for any public use
under any Regulation, or by right of eminent domain, or by private purchase in
lieu thereof, and the taking prevents or materially interferes with the
Permitted Use of the Premises, and this Lease is not terminated as provided in
Paragraph 23.A. above, the Rent payable hereunder during the unexpired portion
of the Lease shall be reduced, beginning on the date when the physical taking
shall have occurred, to such amount as may be fair and reasonable under all of
the circumstances, but only after giving Landlord credit for all sums received
or to be received by Tenant by the condemning authority. Notwithstanding
anything to the contrary contained in this Paragraph, if the temporary use or
occupancy of any part of the Premises shall be taken or appropriated under power
of eminent domain during the Term, this Lease shall be and remain unaffected by
such taking or appropriation and Tenant shall continue to pay in full all Rent
payable hereunder by Tenant during the Term; in the event of any such temporary
appropriation or taking, Tenant shall be entitled to receive that portion of any
award which represents compensation for the use of or occupancy of the Premises
during the Term, and Landlord shall be entitled to receive that portion of any
award which represents the cost of restoration of the Premises and the use and
occupancy of the Premises.

C. AWARD. Landlord shall be entitled to (and Tenant shall assign to Landlord)
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 any sums paid by
virtue of such proceedings, whether or not attributable to the value of any
unexpired portion of this Lease, except as expressly provided in this Lease.
Notwithstanding the foregoing, any compensation specifically and separately
awarded Tenant for Tenant's personal property and moving costs, shall be and
remain the property of Tenant and the unamortized value of improvements to the
Premises paid for by Tenant.

D. WAIVER OF CCP Section 1265.130. Each party waives the provisions of
California Civil Code Procedure Section 1265.130 allowing either party to
petition the superior court to terminate this Lease as a result of a partial
taking.

                               24. CASUALTY DAMAGE

A. GENERAL. If the Premises or Building should be damaged or destroyed by fire,
tornado, or other casualty (collectively, "CASUALTY"), Tenant shall give
immediate written notice thereof to Landlord. Within thirty (30) days after
Landlord's receipt of such notice, Landlord shall notify Tenant whether in
Landlord's estimation (based upon the certificate of a general contractor
reasonably acceptable to Tenant) material restoration of the Premises can
reasonably be made within one hundred eighty (180) days from the date of such
notice and receipt of required permits for such restoration. Landlord's
determination shall be binding on Tenant.

B. WITHIN 180 DAYS. If the Premises or Building should be damaged by Casualty to
such extent that material restoration can in Landlord's estimation be reasonably
completed within one hundred eighty (180) days after the date of such notice and
receipt of required permits for such restoration, this Lease shall not
terminate. Provided that insurance proceeds are received by Landlord to fully
repair the damage (less the amount of any deductible), Landlord shall proceed to
rebuild and repair the Premises in the manner reasonably determined by Landlord,
except that Landlord shall not be required to rebuild, repair or replace any
part of the Alterations which may have been placed on or about the Premises by
Tenant. If the Premises are untenantable in whole or in part following such
damage, the Rent payable hereunder during the period in which they are
untenantable shall be abated proportionately.

C. GREATER THAN 180 DAYS. If the Premises or Building should be damaged by
Casualty to such extent that rebuilding or repairs cannot in Landlord's
estimation be reasonably completed within one hundred eighty (180) days after
the date of such notice and receipt of

                                       15
<PAGE>   45
required permits for such rebuilding or repair, then either party shall have the
option to be exercised within thirty (30) days following receipt of Landlord's
estimate of terminating this Lease effective upon the date of the occurrence of
such damage, in which event the Rent shall be abated during the unexpired
portion of this Lease. If neither party elects to so terminate, Landlord shall
commence to rebuild or repair the Premises diligently and in the manner
reasonably determined by Landlord. Notwithstanding the above, Landlord shall not
be required to rebuild, repair or replace any part of any Alterations which may
have been placed, on or about the Premises by Tenant. If the Premises are
untenantable in whole or in part following such damage, the Rent payable
hereunder during the period in which they are untenantable shall be abated
proportionately.

D. TENANT'S FAULT. Notwithstanding anything herein to the contrary, if the
Premises or any other portion of the Building are damaged by Casualty resulting
from the fault, negligence, or breach of this Lease by Tenant or any of Tenant's
Parties, Base Rent and Additional Rent shall not be diminished during the repair
of such damage (to the extent Tenant is responsible for the loss and Landlord is
not being covered by any other insurance proceeds) and Tenant shall be liable to
Landlord for the cost and expense of the repair and restoration of the Building
caused thereby to the extent such cost and expense is not covered by insurance
proceeds.

E. INSURANCE PROCEEDS. Notwithstanding anything herein to the contrary, if the
Premises or Building are damaged or destroyed and are not fully covered by the
insurance proceeds received by Landlord or if the holder of any indebtedness
secured by a mortgage or deed of trust covering the Premises requires, despite
Landlord's commercially reasonable efforts to obtain such proceeds, that the
insurance proceeds be applied to such indebtedness, then in either case Landlord
shall have the right to terminate this Lease by delivering written notice of
termination to Tenant within thirty (30) days after the date of notice to
Landlord that said damage or destruction is not fully covered by insurance or
such requirement is made by any such holder, as the case may be, whereupon this
Lease shall terminate.

F. WAIVER. This Paragraph 24 shall be Tenant's sole and exclusive remedy in the
event of damage or destruction to the Premises or the Building. As a material
inducement to Landlord entering into this Lease, Tenant hereby waives any rights
it may have under Sections 1932, 1933(4), 1941 or 1942 of the Civil Code of
California with respect to any destruction of the Premises, Landlord's
obligation for tenantability of the Premises and Tenant's right to make repairs
and deduct the expenses of such repairs, or under any similar law, statute or
ordinance now or hereafter in effect.

G. TENANT'S PERSONAL PROPERTY. In the event of any damage or destruction of the
Premises or the Building, under no circumstances shall Landlord be required to
repair any injury or damage to, or make any repairs to or replacements of,
Tenant's personal property.

                                25. HOLDING OVER

Unless Landlord expressly consents in writing to Tenant's holding over, Tenant
shall be unlawfully and illegally in possession of the Premises, whether or not
Landlord accepts any rent from Tenant or any other person while Tenant remains
in possession of the Premises without Landlord's written consent. If Tenant
shall retain possession of the Premises or any portion thereof without
Landlord's consent following the expiration of this Lease or sooner termination
for any reason, then Tenant shall pay to Landlord for each day of such retention
two hundred percent (200%) the amount of daily rental as of the last month prior
to the date of expiration or earlier termination. Tenant shall also indemnify,
defend, protect and hold Landlord harmless from any loss, liability or cost,
including consequential and incidental damages and reasonable attorneys' fees,
incurred by Landlord resulting from delay by Tenant in surrendering the Premises
within thirty (30) days following the expiration or earlier termination of the
Term or extended Term of this Lease, including, without limitation, any claims
made by the succeeding tenant founded on such delay. Acceptance of Rent by
Landlord following expiration or earlier termination of this Lease, or following
demand by Landlord for possession of the Premises, shall not constitute a
renewal of this Lease, and nothing contained in this Paragraph 25 shall waive
Landlord's right of reentry or any other right. Additionally, if upon expiration
or earlier termination of this Lease, or following demand by Landlord for
possession of the Premises, Tenant has not fulfilled its obligation with respect
to repairs and cleanup of the Premises or any other Tenant obligations as set
forth in this Lease, then Landlord shall have the right to perform any such
obligations as it deems necessary at Tenant's sole cost and expense, and any
time required by Landlord to complete such obligations shall be considered a
period of holding over and the terms of this Paragraph 25 shall apply. The
provisions of this Paragraph 25 shall survive any expiration or earlier
termination of this Lease. If by written notice to Landlord delivered not later
than twelve (12) months prior to the Term Expiration Date, or the expiration of
the extended Term (the "Hold-Over Notice"), Tenant advises Landlord of its
intent to hold-over specifying the period of such hold-over (which period must
be for a period of no longer than six (6) months) (the "Hold-Over Term") then
Tenant may, as a matter of right, remain in possession following the Term
Expiration Date or the expiration of the extended Term, as the case may be, for
the Hold-Over Term set forth in the Hold-Over Notice; provided, that the Base
Rent for the Hold-Over Term shall be one hundred fifty percent (150%) of the sum
of the Base Rent and other charges payable for the last month of the Term or
extended Term. In no event under the preceding sentence, shall Tenant have the
right to hold-over in the Premises for more than one (1) six (6) month or
shorter period beyond the Term Expiration Date or the expiration of the extended
Term.

                                   26. DEFAULT

A. EVENTS OF DEFAULT. The occurrence of any of the following shall constitute an
event of default on the part of Tenant:

        (1) ABANDONMENT.

        (2) NONPAYMENT OF RENT. Failure to pay any installment of Rent or any
        other amount due and payable hereunder upon the date when said payment
        is due, as to which time is of the essence.

        (3) OTHER OBLIGATIONS. Failure to perform any obligation, agreement or
        covenant under this Lease other than those matters specified in
        subparagraphs (1) and (2) of this Paragraph 26.A., such failure
        continuing for twenty (20) days after written notice of such failure
        unless such default cannot reasonably be cured within such twenty (20)
        day period and Tenant shall within such period commence with due
        diligence and dispatch the curing of such default, and having so
        commenced, shall thereafter, with periodic written reports submitted to
        Landlord, prosecute or complete with due diligence and dispatch the
        curing of such default, as to which time is of the essence.

        (4) GENERAL ASSIGNMENT. A general assignment by Tenant for the benefit
        of creditors.

        (5) BANKRUPTCY. The filing of any voluntary petition in bankruptcy by
        Tenant, or the filing of an involuntary petition by Tenant's creditors,
        which involuntary petition remains undercharged for a period of thirty
        (30) days. If under applicable law, the trustee in bankruptcy or Tenant
        has the right to affirm this Lease and continue to perform the
        obligations of Tenant hereunder, such trustee or Tenant shall, in such
        time period as may be permitted by the bankruptcy court having
        jurisdiction, cure all

                                       16
<PAGE>   46

        defaults of Tenant hereunder outstanding as of the date of the
        affirmance of this Lease and provide to Landlord such adequate
        assurances as may be necessary to ensure Landlord of the continued
        performance of Tenant's obligations under this Lease.

        (6) RECEIVERSHIP. The employment of a receiver to take possession of
        substantially all of Tenant's assets or the Premises, if such
        appointment remains undismissed or undischarged for a period of fifteen
        (15) days after the order therefor.

        (7) ATTACHMENT. The attachment, execution or other judicial seizure of
        all or substantially all of Tenant's assets or Tenant's leasehold of the
        Premises, if such attachment or other seizure remains undismissed or
        undischarged for a period of fifteen (15) days after the levy thereof.

        (8) INSOLVENCY. The admission by Tenant in writing of its inability to
        pay its debts as they become due.

B. REMEDIES UPON DEFAULT.

        (1) TERMINATION. In the event of the occurrence of any event of default,
        Landlord shall have the right to give a written termination notice to
        Tenant, and on the date specified in such notice, Tenant's right to
        possession shall terminate, and this Lease shall terminate unless on or
        before such date all Rent in arrears and all costs and expenses incurred
        by or on behalf of Landlord hereunder shall have been paid by Tenant and
        all other events of default of this Lease by Tenant at the time existing
        shall have been fully remedied to the satisfaction of Landlord. At any
        time after such termination, Landlord may recover possession of the
        Premises or any part thereof and expel and remove therefrom Tenant and
        any other person occupying the same, including any subtenant or
        subtenants notwithstanding Landlord's consent to any sublease, by any
        lawful means, and again repossess and enjoy the Premises without
        prejudice to any of the remedies that Landlord may have under this
        Lease, or at law or equity by any reason of Tenant's default or of such
        termination. Landlord hereby reserves the right, but shall not have the
        obligation, to recognize the continued possession of any subtenant. The
        delivery or surrender to Landlord by or on behalf of Tenant of keys,
        entry codes, or other means to bypass security at the Premises shall not
        terminate this Lease.

        (2) CONTINUATION AFTER DEFAULT. Even though an event of default may have
        occurred, this Lease shall continue in effect for so long as Landlord
        does not terminate Tenant's right to possession under Paragraph 26.B.(1)
        hereof, and Landlord may enforce all of Landlord's rights and remedies
        under this Lease and at law or in equity, including without limitation,
        the right to recover Rent as it becomes due, and Landlord, without
        terminating this Lease, may exercise all of the rights and remedies of a
        landlord under Section 1951.4 of the Civil Code of the State of
        California or any successor code section. Acts of maintenance,
        preservation or efforts to lease the Premises or the appointment of a
        receiver under application of Landlord to protect Landlord's interest
        under this Lease or other entry by Landlord upon the Premises shall not
        constitute an election to terminate Tenant's right to possession.

        (3) INCREASED SECURITY DEPOSIT. If Tenant is in default under Paragraph
        26.A.(2) hereof and such default remains uncured for ten (10) days after
        such occurrence or such default occurs more than three times in any
        twelve (12) month period, Landlord may require that Tenant increase the
        Security Deposit to the amount of three times the current month's Rent
        at the time of the most recent default.

C. DAMAGES AFTER DEFAULT. Should Landlord terminate this Lease pursuant to the
provisions of Paragraph 26.B.(1) hereof, Landlord shall have the rights and
remedies of a Landlord provided by Section 1951.2 of the Civil Code of the State
of California, or any successor code sections. Upon such termination, in
addition to any other rights and remedies to which Landlord may be entitled
under applicable law or at equity, Landlord shall be entitled to recover from
Tenant: (1) the worth at the time of award of the unpaid Rent and other amounts
which had been earned at the time of termination, (2) the worth at the time of
award of the amount by which the unpaid Rent and other amounts that would have
been earned after the date of termination until the time of award exceeds the
amount of such Rent loss that Tenant proves could have been reasonably avoided;
(3) the worth at the time of award of the amount by which the unpaid Rent and
other amounts for the balance of the Term after the time of award exceeds the
amount of such Rent loss that the Tenant proves could be reasonably avoided; and
(4) any other amount and court costs necessary to compensate Landlord for all
detriment proximately caused by Tenant's failure to perform Tenant's obligations
under this Lease or which, in the ordinary course of things, would be likely to
result therefrom. The "worth at the time of award" as used in (1) and (2) above
shall be computed at the Applicable Interest Rate (defined below). The "worth at
the time of award" as used in (3) above shall be computed by discounting such
amount at the Federal Discount Rate of the Federal Reserve Bank of San Francisco
at the time of award plus one percent (1%).

D. LATE CHARGE. In addition to its other remedies, Landlord shall have the right
without notice or demand to add to the amount of any payment required to be made
by Tenant hereunder, and which is not paid and received by Landlord on or before
the fifth business day of each calendar month, an amount equal to (i) two and
one-half percent (2.5%) for the first late payment during any calendar year, and
(ii) five percent (5%) for the second and subsequent late payment during any
calendar year of the delinquency for each month or portion thereof that the
delinquency remains outstanding to compensate Landlord for the loss of the use
of the amount not paid and the administrative costs caused by the delinquency,
the parties agreeing that Landlord's damage by virtue of such delinquencies
would be extremely difficult and impracticable to compute and the amount stated
herein represents a reasonable estimate thereof, provided, however, that on one
(1) occasion during any calendar year of the Term, Landlord shall give Tenant
written notice of such late payment and Tenant shall have a period of five (5)
calendar days thereafter in which to make such payment before any late charge
shall be assessed. Any waiver by Landlord of any late charges or failure to
claim the same shall not constitute a waiver of other late charges or any other
remedies available to Landlord.

E. INTEREST. Interest shall accrue on all sums not paid when due hereunder at
the lesser of fourteen percent (14%) per annum or the maximum interest rate
allowed by law ("APPLICABLE INTEREST RATE") from the due date until paid.

F. REMEDIES CUMULATIVE. All rights, privileges and elections or remedies of the
parties are cumulative and not alternative, to the extent permitted by law and
except as otherwise provided herein.

G. LANDLORD'S DEFAULT. Landlord shall not be in default hereunder unless
Landlord fails to perform any material obligation required of Landlord under the
terms of this Lease within a reasonable time, but in no event later than sixty
(60) days after written notice by Tenant to Landlord, subject to Paragraph 35 of
this Lease, specifying the nature of Landlord's failure to perform. If, however,
the nature of Landlord's obligation is such that more than sixty (60) days are
reasonably required for performance, then Landlord shall not be in default
hereunder if Landlord commences performance within such sixty (60) day period,
subject to Paragraph 35 of this Lease, and thereafter diligently prosecutes such
cure to completion. If Landlord at the expiration of such notice and cure
periods has failed to cure such default, then, subject to the exculpatory
provisions of this Paragraph 26, Tenant may pursue any of its legal or equitable
remedies, but Tenant shall have no right to otherwise terminate this Lease.
Notwithstanding the foregoing, nothing contained in this Paragraph 26.G. shall
be deemed to expand Tenant's remedies under circumstances where particular
provisions of this Lease expressly provide for an available remedy and where
such available remedies are so set forth they shall be deemed Tenant's exclusive
remedy.

                                       17
<PAGE>   47

                                    27. LIENS

Tenant shall at all times keep the Premises and the Project free from liens
arising out of or related to work or services performed, materials or supplies
furnished or obligations incurred by or on behalf of Tenant or in connection
with work made, suffered or done by or on behalf of Tenant in or on the Premises
or Project. If Tenant shall not, within ten (10) days following the imposition
of any such lien, cause the same to be released of record by payment or posting
of a proper bond, Landlord shall have, in addition to all other remedies
provided herein and by law, the right, but not the obligation, to cause the same
to be released by such means as Landlord shall deem proper, including payment of
the claim giving rise to such lien. All sums paid by Landlord on behalf of
Tenant and all expenses incurred by Landlord in connection therefor shall be
payable to Landlord by Tenant on demand with interest at the Applicable Interest
Rate as Additional Rent. Landlord shall have the right at all times to post and
keep posted on the Premises any notices permitted or required by law, or which
Landlord shall deem proper, for the protection of Landlord, the Premises, the
Project and any other party having an interest therein, from mechanics' and
materialmen's liens, and Tenant shall give Landlord not less than ten (10)
business days prior written notice of the commencement of any work in the
Premises or Project which could lawfully give rise to a claim for mechanics' or
materialmen's liens to permit Landlord to post and record a timely notice of
non-responsibility, as Landlord may elect to proceed or as the law may from time
to time provide, for which purpose, if Landlord shall so determine, Landlord may
enter the Premises. Tenant shall not remove any such notice posted by Landlord
without Landlord's consent, and in any event not before completion of the work
which could lawfully give rise to a claim for mechanics' or materialmen's liens.

                                28. SUBSTITUTION

A.

                            29. TRANSFERS BY LANDLORD

In the event of a sale or conveyance by Landlord of the Building or a
foreclosure by any creditor of Landlord, the same shall operate to release
Landlord from any liability upon any of the covenants or conditions, express or
implied, herein contained in favor of Tenant, to the extent required to be
performed after the passing of title to Landlord's successor-in-interest. In
such event, Tenant agrees to look solely to the responsibility of the
successor-in-interest of Landlord under this Lease with respect to the
performance of the covenants and duties of "Landlord" to be performed after the
passing of title to Landlord's successor-in-interest provided such
successor-in-interest assumes in writing Landlord's duties, obligations or
liabilities hereunder. This Lease shall not be affected by any such sale and
Tenant agrees to attorn to the purchaser or assignee. Landlord's
successor(s)-in-interest shall not have liability to Tenant with respect to the
failure to perform any of the obligations of "Landlord," to the extent required
to be performed prior to the date such successor(s)-in-interest became the owner
of the Building.

               30. RIGHT OF LANDLORD TO PERFORM TENANT'S COVENANTS

All covenants and agreements to be performed by Tenant under any of the terms of
this Lease shall be performed by Tenant at Tenant's sole cost and expense and
without any abatement of Rent, except as otherwise expressly set forth herein.
If Tenant shall fail to pay any sum of money, other than Base Rent, required to
be paid by Tenant hereunder or shall fail to perform any other act on Tenant's
part to be performed hereunder, including Tenant's obligations under Paragraph
11 hereof, and such failure shall continue for fifteen (15) days after notice
thereof by Landlord, in addition to the other rights and remedies of Landlord,
Landlord may make any such payment and perform any such act on Tenant's part. In
the case of an emergency, no prior notification by Landlord shall be required.
Landlord may take such actions without any obligation and without releasing
Tenant from any of Tenant's obligations. All sums so paid by Landlord and all
incidental costs incurred by Landlord and interest thereon at the Applicable
Interest Rate, from the date of payment by Landlord, shall be paid to Landlord
on demand as Additional Rent.

                                   31. WAIVER

If either Landlord or Tenant waives the performance of any term, covenant or
condition contained in this Lease, such waiver shall not be deemed to be a
waiver of any subsequent breach of the same or any other term, covenant or
condition contained herein, or constitute a course of dealing contrary to the
expressed terms of this Lease. The acceptance of Rent by Landlord shall not
constitute a waiver of any preceding breach by Tenant of any term, covenant or
condition of this Lease, regardless of Landlord's knowledge of such preceding
breach at the time Landlord accepted such Rent. Failure by Landlord to enforce
any of the terms, covenants or conditions of this Lease for any length of time
shall not be deemed to waive or decrease the right of Landlord to insist
thereafter upon strict performance by Tenant. Waiver by Landlord of any term,
covenant or condition contained in this Lease may only be made by a written
document signed by Landlord, based upon full knowledge of the circumstances.

                                   32. NOTICES

Each provision of this Lease or of any applicable governmental laws, ordinances,
regulations and other requirements with reference to sending, mailing, or
delivery of any notice or the making of any payment by Landlord or Tenant to the
other shall be deemed to be complied with when and if the following steps are
taken:

A. RENT. All Rent and other payments required to be made by Tenant to Landlord
hereunder shall be payable to Landlord at Landlord's Remittance Address set
forth in the Basic Lease Information, or at such other address as Landlord may
specify from time to time by written notice delivered in accordance herewith.
Tenant's obligation to pay Rent and any other amounts to Landlord under the
terms of this Lease shall not be deemed satisfied until such Rent and other
amounts have been actually received by Landlord.

B. OTHER. All notices, demands, consents and approvals which may or are required
to be given by either party to the other hereunder shall be in writing and
either personally delivered, sent by commercial overnight courier, mailed,
certified or registered, postage prepaid or sent by facsimile with confirmed
receipt (and with an original sent by commercial overnight courier), and in each
case addressed to the party to be notified at the Notice Address for such party
as specified in the Basic Lease Information or to such other place as the party
to be notified may from time to time designate by at least fifteen (15) days
notice to the notifying party. Notices shall be deemed served upon receipt or
refusal to accept delivery.

                                       18
<PAGE>   48

C. REQUIRED NOTICES. Tenant shall immediately notify Landlord in writing of any
notice of a violation or a potential or alleged violation of any Regulation that
relates to the Premises or the Project, or of any inquiry, investigation,
enforcement or other action that is instituted or threatened by any governmental
or regulatory agency against Tenant or any other occupant of the Premises, or
any claim that is instituted or threatened by any third party that relates to
the Premises or the Project.

                               33. ATTORNEYS' FEES

If Landlord places the enforcement of this Lease, or any part thereof, or the
collection of any Rent due, or to become due hereunder, or recovery of
possession of the Premises in the hands of an attorney, Tenant shall pay to
Landlord, upon demand, Landlord's reasonable attorneys' fees and court costs,
whether incurred at trial, appeal or review. In any action which Landlord or
Tenant brings to enforce its respective rights hereunder, the unsuccessful party
shall pay all costs incurred by the prevailing party including reasonable
attorneys' fees, to be fixed by the court, and said costs and attorneys' fees
shall be a part of the judgment in said action.

                           34. SUCCESSORS AND ASSIGNS

This Lease shall be binding upon and inure to the benefit of Landlord, its
successors and assigns, and shall be binding upon and inure to the benefit of
Tenant, its successors, and to the extent assignment is approved by Landlord as
provided hereunder, Tenant's assigns.

                                35. FORCE MAJEURE

If performance by a party of any portion of this Lease is made impossible by any
prevention, delay, or stoppage caused by strikes, lockouts, labor disputes, acts
of God, inability to obtain services, labor, or materials or reasonable
substitutes for those items, government actions, civil commotions, fire or other
casualty, or other causes beyond the reasonable control of the party obligated
to perform, performance by that party for a period equal to the period of that
prevention, delay, or stoppage is excused. Tenant's obligation to pay Rent,
however, is not excused by this Paragraph 35.

                            36. SURRENDER OF PREMISES

Tenant shall, upon expiration or sooner termination of this Lease, surrender the
Premises to Landlord in the same condition as existed on the date Tenant
originally took possession thereof (reasonable wear and tear, casualty damage
and acts of God excepted), including, but not limited to, all holes in walls
repaired, all HVAC equipment in operating order and in good repair, and all
floors cleaned, waxed, and free of any Tenant-introduced marking or painting,
all to the reasonable satisfaction of Landlord. Tenant shall remove all of its
debris from the Project. At or before the time of surrender, Tenant shall comply
with the terms of Paragraph 12.A. hereof with respect to Alterations to the
Premises and all other matters addressed in such Paragraph. If the Premises are
not so surrendered at the expiration or sooner termination of this Lease, the
provisions of Paragraph 25 hereof shall apply. All keys to the Premises or any
part thereof shall be surrendered to Landlord upon expiration or sooner
termination of the Term. Tenant shall meet with Landlord for a joint inspection
of the Premises fifteen (15) days prior to vacating, but nothing contained
herein shall be construed as an extension of the Term or as a consent by
Landlord to any holding over by Tenant. In the event of Tenant's failure to give
such notice or participate in such joint inspection, Landlord's inspection at or
after Tenant's vacating the Premises shall conclusively be deemed correct for
purposes of determining Tenant's responsibility for repairs and restoration. Any
delay caused by Tenant's failure to carry out its obligations under this
Paragraph 36 beyond the term hereof, shall constitute unlawful and illegal
possession of Premises under Paragraph 25 hereof.

                                37. MISCELLANEOUS

A. GENERAL. The term "Tenant" or any pronoun used in place thereof shall
indicate and include the masculine or feminine, the singular or plural number,
individuals, firms or corporations, and their respective successors, executors,
administrators and permitted assigns, according to the context hereof.

B. TIME. Time is of the essence regarding this Lease and all of its provisions.

C. CHOICE OF LAW. This Lease shall in all respects be governed by the laws of
the State of California.

D. ENTIRE AGREEMENT. This Lease, together with its Exhibits, addenda and
attachments and the Basic Lease Information, contains all the agreements of the
parties hereto and supersedes any previous negotiations. There have been no
representations made by the Landlord or understandings made between the parties
other than those set forth in this Lease and its Exhibits, addenda and
attachments and the Basic Lease Information.

E. MODIFICATION. This Lease may not be modified except by a written instrument
signed by the parties hereto. Tenant accepts the area of the Premises as
specified in the Basic Lease Information as the approximate area of the Premises
for all purposes under this Lease, and acknowledges and agrees that no other
definition of the area (rentable, usable or otherwise) of the Premises shall
apply. Tenant shall in no event be entitled to a recalculation of the square
footage of the Premises, rentable, usable or otherwise, and no recalculation, if
made, irrespective of its purpose, shall reduce Tenant's obligations under this
Lease in any manner, including without limitation the amount of Base Rent
payable by Tenant or Tenant's Proportionate Share of the Building and of the

through or under Landlord, subject, nevertheless, to all of the other terms and
conditions of this Lease. Landlord shall not be liable for any hindrance,
interruption, interference or disturbance by other tenants or third persons, nor

hindrance, interruption, interference or disturbance.

P. COUNTERPARTS. This Lease may be executed in any number of counterparts, each

maintain the Building in a manner generally consistent with other comparable
first-class business park projects in San Diego County.

T. LANDLORD'S COVENANT. In connection with the exercise by Landlord of the
rights and reservations granted or afforded by this Lease, Landlord hereby
covenants and agrees to:

        (1)  use its reasonable good faith efforts to avoid taking any actions
             (excepting any actions to comply with Regulations) which may
             materially adversely affect Tenant's use of or normal business
             operations within the Premises;

        (2)  use its reasonable good faith efforts to provide Tenant with prior
             written notice of any such actions by Landlord (excepting any
             actions to comply with Regulations) which may materially adversely
             affect Tenant's use of or normal business operations within the
             Premises and at least forty-eight (48) hours prior written notice
             of any scheduled work to be performed by Landlord which may
             materially adversely interfere with Tenant's normal business
             operations; it being understood, however, that the giving of such
             prior written notice may be impossible or impractical under
             emergency circumstances;

        (3)  in a manner consistent with the prudent and efficient operation of
             the Project, to reasonable coordinate and reasonably cooperate with
             Tenant to reasonably minimize any cessation or degradation of
             Tenant's use of or normal business operations within the Premises;
             and

        (4)  use its reasonable good faith efforts to perform all work in an
             expeditious and workmanlike manner and to restore access to the
             Premises and the availability of Building services as soon as
             reasonably practicable.

Notwithstanding anything contained in this Paragraph 37.T. to the contrary, in
no event shall Landlord be liable or responsible for any consequential or
exemplary damages.

U. CONSENT/DUTY TO ACT REASONABLY. Except for the provisions of this Lease which
expressly grant a party the right to act in its sole discretion, whereupon in
each such case, Landlord's and Tenant's duty is to act in good faith (but shall
not otherwise be subject to a "reasonableness" standard) (i) any time the
consent of Landlord or Tenant is required, such consent shall not be
unreasonably withheld, delayed or conditioned, and (ii) whenever this Lease
grants Landlord or Tenant the right to take action, exercise discretion,
establish rules and regulations or make allocations or other determinations,
Landlord and Tenant shall act reasonably and in good faith and take no action
which might result in the frustration of the other party's reasonable
expectations concerning the benefits to be enjoyed under this Lease.

V. YEAR 2000 COMPLIANCE. Landlord hereby represents, warrants and covenants to
the best of its knowledge to Tenant that all of the Project's mechanical,
electrical, elevator, fire and life safety systems (the "Building Systems") will
operate on and after January 1, 2000 without normal operation being impaired by
dates in and after the year 2000. At Tenant's request, Landlord shall provide
Tenant with reasonably satisfactory evidence of the Building Systems' compliance
with the foregoing.

                            38. ADDITIONAL PROVISIONS

</TABLE>

B. RENEWAL OPTION. Provided Tenant is not, and has not been, in material default
of any of its obligations under this Lease or any other lease Tenant may have in
the Project, after expiration of all applicable grace, notice and cure periods,
it shall have an option to renew this Lease for the Premises in "as is"
condition for two (2) five (5) year periods on the same terms and conditions as
set forth in this Lease except that the Base Rent of each option period shall be
the then fair prevailing market rate rental for comparable space of at least one
hundred thousand (100,000) square feet at comparable buildings within the
Eastgate Technology Park and University Towne Centre areas, as defined and
determined by Subparagraph 38.B(1) and/or 38 B.(2) below. In no event will the
Base Rent for each option period be less than that of the previous period.
Tenant shall give Landlord written notice to exercise its option at least
eighteen (18) months but not more than fifteen (15) months prior to the
expiration of the Term, or extended Term.

        Notwithstanding anything to the contrary herein contained, Tenant's
right to extend the Term by exercise of the foregoing option shall be
conditioned upon the following: (a) at the time of the exercise of the option,
and at the time of the commencement of the extended Term, Tenant shall be in
possession of and occupying at least seventy-five percent (75%) of the Premises,
and at least seventy-five percent (75%) of all other premises under any other
leases Tenant may have in the Project, for the conduct of its business therein
and the same shall not be occupied by any assignee, subtenant, or licensee; and
(b) the notice of exercise shall constitute a representation, by commencement of
the extended Term, that Tenant does not intend to seek to assign more than
twenty-five percent (25%) of the Lease, or sublet more than twenty-five percent
(25%) of any other premises under any other leases Tenant may have in the
Project.

(1) "Fair Market Rental" shall mean the rate being charged to tenants recently
    renewing existing leases for comparable space in buildings within the
    Eastgate Technology Park and University Towne Centre areas, taking into
    consideration all relevant factors, including but not limited to, the
    following: size, location, floor level, proposed term of the lease, expense
    stops, extent of building services to be provided, and the time that the
    rental rate under consideration is to become effective. Fair Market Rental
    as of the commencement of each option period shall be determined by Landlord
    with written notice (the "Notice") given to Tenant not later than thirty
    (30) days after the receipt of the option notice, subject to Tenant's right
    to arbitration as provided in Subparagraph 38.B(2) below. Failure on the
    part of Tenant to demand arbitration within thirty (30) days after receipt
    of the Notice from Landlord shall bind Tenant to the Fair Market Rental as
    determined by Landlord. Notwithstanding anything to contrary herein,
    Tenant's right to arbitrate shall conclude no later than ninety (90) days
    after the date of the Notice.

(2) If Tenant disputes the amount claimed by Landlord as Fair Market Rental,
    Tenant may require that Landlord submit the dispute to arbitration. The
    arbitration shall be conducted and determined in San Diego, California, in
    accordance with the then prevailing rules of the American Arbitration
    Association or its successor for arbitration of commercial disputes, except
    that the procedures mandated by such rules shall be modified as follows:

    (a) Tenant shall make demand for arbitration in writing within thirty (30)
    days after service of the Notice, specifying therein the name and address of
    the person to act as the arbitrator on Tenant's behalf. The arbitrator shall
    be a M.A.I. designated and independent real estate appraiser with at least
    ten (10) years full-time commercial appraisal experience who is familiar
    with the Fair Market Rental of first-class business park space in San Diego
    County. (In the event M.A.I. appraisers are no longer available, a
    comparable designation with at least ten (10) years experience with
    commercial property appraisal in San Diego County will be acceptable.)
    Failure on the part of Tenant to make the timely and proper demand for such
    arbitration shall constitute a waiver of the right thereto. Within ten (10)
    business days after the service of the demand for arbitration, Landlord
    shall give notice to Tenant specifying the name and address of the person
    designated by Landlord to act as arbitrator on its behalf, which arbitrator
    shall be similarly qualified. If Landlord fails to notify Tenant of the
    appointment of its arbitrator, within or by the time specified, then the
    arbitrator appointed by Tenant shall be the arbitrator to determine the Fair
    Market Rental for the Premises.

    (b) If two arbitrators are chosen pursuant to Subparagraph 38.B.(2)(a)
    above, the arbitrators so chosen shall meet within ten (10) business days
    after the second arbitrator is appointed and shall appoint a third
    arbitrator, who shall be a competent and impartial person with
    qualifications similar to those required of the first two arbitrators
    pursuant to Subparagraph 38.B(2)(a) above. If they are unable to agree upon
    such appointment within five (5) business days after expiration of such ten
    (10) day period, the third arbitrator shall be selected by the parties
    themselves. If the parties do not agree on the third arbitrator within five
    (5) business days after expiration of the foregoing five (5) business day
    period, then either party, on behalf of both, may request appointment of
    such a qualified arbitrator by (i) the majority of board members of the San
    Diego County Chapter of M.A.I. appraisers, or (ii) the chief arbitrator of
    the San Diego County Chapter of the American Arbitration Association. The
    three arbitrators shall decide the dispute, if has not been previously
    resolved, by following the procedures set forth in Subparagraph 38.B(2)(c)
    below. Each party shall pay the fees and expenses of its respective
    arbitrator and both shall share the fees and expenses of the third
    arbitrator. Attorneys' fees and expenses of counsel and of witnesses or
    other experts for the respective parties shall be paid by the respective
    party engaging such counsel or calling such witnesses or other experts.

    (c) The Fair Market Rental shall be fixed by the three arbitrators in
    accordance with the following procedures. Each of the arbitrators selected
    by the parties shall state, in writing, his or her determination of the Fair
    Market Rental supported by the reasons therefor and shall make counterpart
    copies for each of the other arbitrators. The arbitrators shall arrange for
    a simultaneous exchange of such proposed resolutions within ten (10)
    business days after appointment of the third arbitrator. If either
    arbitrator fails to deliver to the other arbitrators his or her
    determination within such ten (10) business day period, then the
    determination of the other arbitrator shall be final and binding upon the
    parties. The role of the third arbitrator shall be to select which of the
    two proposed resolutions most closely approximates his or her determination
    of Fair Market Rental. The third arbitrator shall have no right to propose a
    middle ground or any modification of either of the two proposed resolutions.
    The resolution he or she chooses as the most closely approximating his or
    her determination of the Fair Market Rental shall constitute the decision of
    the arbitrators and shall be final and

                                       21
<PAGE>   51

    binding upon the parties. If either party fails to pay its share of the fees
    of the third arbitrator within thirty (30) days after receipt of an invoice,
    or fails to execute and deliver any documents reasonably required by the
    third arbitrator within thirty (30) days after receipt thereof, then the
    Fair Market Rental shall be determined solely by the arbitrator selected by
    the other party.

(d) In the event of a failure, refusal or inability of any arbitrator to act,
    his or her successor shall be appointed by him or her, but in the case of
    the third arbitrator, his or her successor shall be appointed in the same
    manner as that set forth herein with respect to the appointment of the
    original third arbitrator. The arbitrators shall attempt to decide the issue
    within ten (10) business days after the appointment of the third arbitrator.
    Any decision in which the arbitrator appointed by Landlord and the
    arbitrator appointed by Tenant concur shall be binding and conclusive upon
    the parties, except that such arbitrators shall not attempt by themselves to
    mutually ascertain the Fair Market Rental and any such determination, in a
    manner other than that provided for in Subparagraph 38.B(2)(c) hereof, shall
    not be binding on the parties.

C. ALTERNATIVE TERM EXPIRATION DATE. Subject to Tenant and Landlord completing a
lease and other related documentation for approximately 150,000 square feet
within the Project which adjoins the Premises ("Expansion Premises") and Tenant
taking full occupancy and commencing the payment of Rent, Tenant shall have the
right to alter the Term Expiration Date upon written notice to Landlord no
sooner than twenty-four (24) months and no later than eighteen (18) months prior
to the scheduled Term Expiration Date. This alteration of the Premises' Term
Expiration Date shall consist of exchanging the term expiration date of the
Expansion Premises with the Term Expiration Date for the Premises. In this
event, monthly Base Rent for the period beyond the scheduled Term Expiration
Date and through the new Term Expiration Date, as modified by the immediately
preceding sentence, shall be the then prevailing market rate for comparable
space within Bridge Pointe Corporate Centre and comparable office buildings in
the Eastgate Technology Park area, as reasonably determined by Landlord. In no
event will the Base Rent be less than that of the previous period. Landlord
shall submit to Tenant the then prevailing market rate by a written notice given
to Tenant not later than thirty (30) days after the receipt of the Tenant's
notice to alter the Term Expiration Date. Tenant shall have fifteen (15) days to
accept said rental rate or Tenant's right to alter the Term Expiration Date
hereunder shall terminate.

D. PREPAID RENT. Upon execution of this Lease, Tenant shall pay the first and
second month's Base Rent for the entire Premises, totaling Three Hundred
Seventy-one Thousand Seven Hundred Sixty Dollars $371,760.00 ("Pre-paid Rent").
Landlord shall apply the Pre-paid Rent to the Base Rent for the Premises as they
become due during the initial months of the Term.

E. FIRST RIGHT OF OFFER TO LEASE. Tenant is granted a first right of offer to
lease Building 2 of Phase A of the Project located at 4790 Eastgate Mall, which
is approximately sixty thousand nine hundred 60,900 rentable square feet,
("Building 2") when it comes available (termination of the Building 2 tenant's
lease obligation, right and interest to Building 2) at the end of the initial
term of such lease, or at the end of any option period for Building 2, if the
existing tenant thereof elects to extend the term of such lease, on the
following terms: Before Landlord enters into a lease for Building 2, and
provided Tenant is not then in default under this Lease, or any other lease
Tenant may have in the Project, after any applicable grace, notice and cure
periods, and has not been in material default of any terms or conditions of this
Lease, or any other lease Tenant may have in the Project, and provided Tenant
has not assigned or sublet more than twenty-five percent (25%) of its Premises,
or any other premises under any other leases Tenant may have in the Project.
Landlord will so notify Tenant in writing and propose a rent and other lease
terms and conditions ("Landlord's Notice"). Tenant shall have five (5) days
after notification to notify Landlord in writing of its intent to pursue
negotiations. Thereafter, Landlord and Tenant shall negotiate in good faith in
an attempt to reach an agreement on the terms of the lease for Building 2. If
Tenant exercises this first right of offer in the manner prescribed, Tenant
shall immediately deliver to Landlord payment for the first month's rent for
Building 2 (in the same manner as provided for in this Lease), and the lease for
Building 2 will be consummated without delay in accordance with the terms and
conditions set forth in Landlord's Notice. If Landlord and Tenant are unable to
agree in writing within ten (10) days after Landlord's notice to Tenant,
Landlord may lease Building 2 to another tenant. Thereafter, Tenant's first
right of offer to lease Building 2 shall terminate, and Landlord shall be
relieved from any further obligations to lease Building 2 to Tenant.

F. TERMINATION RIGHTS. Notwithstanding anything to the contrary contained in
this Lease, if Tenant is notified by Landlord, or Tenant becomes aware and
notifies Landlord of the occurrence of a Trigger Event (defined below), and such
Trigger Event materially adversely affects the operation of Tenant's normal
business in, use of, prevents Tenant's reasonable access to the Premises, and
such Trigger Event continues for such a time greater than twelve (12) months
(the "Maximum Restoration Period"), then Tenant may elect to exercise an ongoing
right to terminate this Lease, upon thirty (30) days' prior written notice sent
to Landlord within a period of sixty (60) days following the later of the
occurrence of the Trigger Event or Tenant's receipt (or giving) of notice
thereof (such notice, in the case of a Trigger Event described in subparagraphs
(1) and (2) below, to contain a reasonably detailed description of the scope of
the Trigger Event). Notwithstanding the forgoing, Tenant shall not have a right
to so terminate this Lease if Landlord takes action within said sixty (60) day
period (but no later than the expiration of the thirty (30) day period) which
will result in the restoration of the Tenant's normal business operations in,
Tenant's reasonable access to, and Tenant's use of the Premises in a condition
suitable for the efficient conduct of Tenant's normal business (including,
without limitation, utilities required or necessary for the operation of
Tenant's normal business in the Premises) prior to the end of the Maximum
Restoration Period.

As used herein, the term "TRIGGER EVENT" shall mean and refer to:

        (1) continuous interruption of electrical, water, telecommunication,
    telephone, gas, sewer or other essential utility services used or required
    in connection with Tenant's occupancy of the Premises or interruption of
    Tenant's access to the Premises;

        (2) discovery of Hazardous Materials or any other material environmental
    condition in, on or around the land, Building, Project, common areas or
    Premises, which, taking into account applicable environmental laws, either
    is unlawful or represents a significant health risk to occupants of the
    Premises, excepting those Hazardous Materials either:

        (a)  used by Tenant's contractor in the construction of Alterations in
             the Premises; or

        (b)  generated by Tenant or brought onto or into the Project, Building,
             Premises or common areas, by Tenant as more particularly described
             in Paragraph 4.D. of this Lease.

G. ROOFTOP COMMUNICATIONS EQUIPMENT. During the Term of this Lease (and any
renewal or extensions thereof), Tenant shall have the right, without payment of
any fee or charge therefor, to install and operate, for Tenant's personal use
only, one (1) microwave transmitter-receiver or satellite dish (the "Satellite
Dish") on one Building rooftop (the "Designated Building") of a weight, height,
and width reasonably acceptable to Landlord. Landlord shall not withhold its
consent to the installation of a Satellite Dish reasonably comparable to those
installed within the Project. Tenant's rights pursuant to this Paragraph 38.G.
are subject to the following:

        (1) All costs for the installation of the Satellite Dish including, but
        not limited to, electrical equipment and connections, mounting fixtures,
        engineering studies, inspections, permits, etc. will be at the Tenant's
        sole cost, expense and responsibility.

                                       22
<PAGE>   52

        (2) Prior to installing the Satellite Dish, Tenant must notify Landlord
        in writing, specifying the type, character, size, location, amount of
        space required, installation details and electrical requirements.
        Landlord in its reasonable discretion shall approve of said
        specifications of the Satellite Dish within ten (10) days following
        receipt of Tenant's written request to install a Satellite Dish on the
        roof of the Designated Building.

        (3) Tenant shall pay any federal, state and local taxes applicable to
        the installation and use of the Satellite Dish and Tenant shall procure,
        maintain and pay for and obtain all fees, permits and governmental
        agency licenses necessary in connection with all installation,
        maintenance and operation of the Satellite Dish; provided, however, that
        Landlord shall reasonably cooperate with the efforts of Tenant in
        connection with any governmental application or filing required thereby.
        Tenant shall reimburse Landlord for any actual costs Landlord may incur
        to assist Tenant as detailed in the preceding sentence.

        (4) Tenant shall be permitted, at its sole cost, expense and
        responsibility, but without separate charge other than any charges
        permitted to be imposed by Landlord under Paragraph 7, to install,
        modify, alter, repair, maintain, operate and replace one (1) existing
        chaseway of the Designated Building in an area in the core of the
        Designated Building, one (1) non-dedicated conduit for its cabling use
        (and the use of the Satellite Dish and cable contained therein
        connecting to such building's roof for operation of Tenant's Satellite
        Dish). All installations required in connection with the Satellite Dish
        shall be made by means of conduits, wires or cables that will pass
        through existing openings in the walls or roof decks of the Designated
        Building, and all cable and wires located on the roof of the Designated
        Building used in connection with Satellite Dish shall be covered by
        rust-proof conduits and attachments. In no event shall any of Tenant's
        installations be made through the roof surface or membrane of the
        Designated Building without the prior written consent of Landlord, which
        consent may be withheld in Landlord's sole and absolute discretion. The
        installation of the Satellite Dish shall be subject to Landlord's review
        and approval and shall conform to the engineering standards commonly
        used for installing similar satellite dishes within the Project.

        (5) Tenant, at its sole cost, expense, and responsibility, will comply
        with all present and future laws, and with any reasonable requirements
        of any applicable fire rating bureau relating to the maintenance, use,
        installation and operation of the Satellite Dish. Tenant shall install,
        maintain and operate all of its equipment used in connection with the
        Satellite Dish in conformity with all Regulations of all government
        agencies having jurisdiction over the installation, use and operation of
        the Satellite Dish, including, without limitation, the Federal Aviation
        Administration and the Federal Communications Commission; provided,
        however, that if compliance with such laws or regulations would require
        a change in the size, configuration or location of the Satellite Dish,
        such changes shall be subject to Landlord's prior written consent.

        (6) Prior to the expiration or earlier termination of the Term of this
        Lease, or any extended Term, Tenant shall remove the Satellite Dish and
        all wires and cables used in connection with the Satellite Dish, and
        shall restore and repair all damage to the Designated Building
        occasioned by the installation, maintenance or removal of the Satellite
        Dish. If Tenant fails to timely complete such removal, restoration and
        repair, all sums incurred by Landlord to complete such work shall be
        paid by Tenant to Landlord upon demand.

        (7) Landlord makes no representations or warranties whatsoever with
        respect to the fitness or suitability of the Designated Building for the
        installation, maintenance and operation of the Satellite Dish,
        including, without limitation, with respect to the quality and clarity
        or any receptions and transmissions to or from the Satellite Dish and
        the presence of any interference with such signals, whether emanating
        from the Designated Building or otherwise. Landlord shall permit Tenant
        to have reasonable access to such other parts of the Designated Building
        as are open to the public or for which access is otherwise reasonably
        necessary in order to install, maintain and operate the Satellite Dish.
        Notwithstanding anything set forth in this Paragraph 38.G. to the
        contrary, if Landlord reasonably determines that the installation of the
        Satellite Dish will be detrimental to the design or structural soundness
        of the Designated Building or will create risk of injury or damage to
        persons or property, Tenant shall not be permitted to install said
        Satellite Dish.

        (8) Tenant must notify Landlord in writing prior to the scheduled date
        Tenant proposes to install the Satellite Dish on the roof of the
        Designated Building in order to make arrangements for the movement of
        materials needed in connection with the installation of the Satellite
        Dish.

        (9) Tenant shall provide at its sole cost, expense and responsibility,
        adequate maintenance personnel in order to ensure the safe operation of
        the Satellite Dish. In addition, Tenant shall install, maintain and
        operate all of its equipment used in connection with the Satellite Dish
        in a fashion and manner so as not to interfere with the use and
        operation of any: (a) other televisions or radio equipment in the
        Designated Building; (b) present or future electronic control system for
        any operating services or the operation of the elevators in any building
        within the Project; (c) other transmitting, receiving or master
        television, telecommunications or microwave antenna equipment currently
        located on the roof of the Designated Building or other buildings within
        the Project; or (d) any radio communication system now used by Landlord
        and/or other tenants of the Project. In addition, Tenant shall use its
        commercially reasonable efforts to ensure that Tenant will not interfere
        with any equipment installed by Landlord and/or other tenants of the
        Project in the future. Landlord shall use its commercially reasonable
        efforts to ensure that Tenant's equipment will not be unreasonably
        interfered with.

H. EMERGENCY GENERATOR. During the Term or extended Term of this Lease, upon
written approval by Landlord, which shall not be unreasonably withheld, delayed
or conditioned, Tenant shall have the right, at its sole cost, expense and
responsibility, in accordance with all applicable laws and in a location as
determined by Landlord, to install one (1) emergency electrical generator per
Building and all appurtenant equipment. The maintenance and operation of said
equipment shall be at Tenant's sole cost, expense and responsibility and subject
to Paragraph 11 of this Lease.

    entrances, elevators and stairways are not for the use of the general public
    and Landlord shall in all cases retain the right to control and prevent
    access thereto by all persons whose presence, in the judgment of Landlord,
    shall be prejudicial to the safety, character, reputation and interests of
    the Building, the Project and its tenants, provided that nothing herein
    contained shall be construed to prevent such access to persons with whom any
    tenant normally deals in the ordinary course of such tenant's business
    unless such persons are engaged in illegal activities. No tenant, and no
    employees or invitees of any tenant, shall go upon the roof of any Building,
    except as authorized by Landlord.

    placard, banner, picture, name, advertisement, or notice without notice to
    and at the expense of Tenant, which were installed or displayed in violation
    of this rule. If Landlord shall have given such consent to Tenant at any
    time, whether before or after the execution of Tenant's Lease, such consent
    shall in no way operate as a waiver or release of any of the provisions
    hereof or of the Lease, and shall be deemed to relate only to the particular
    sign, placard, banner, picture, name, advertisement or notice so consented
    to by Landlord and shall not be construed as dispensing with the necessity
    of obtaining the specific written consent of Landlord with respect to any
    other such sign, placard, banner, picture, name, advertisement or notice.
    All approved signs or lettering on doors and walls shall be printed,
    painted, affixed or inscribed at the expense of Tenant by a person or vendor

    it considers appropriate for the safety of tenants and protection of the

                             IMPROVEMENT AGREEMENT

               This Improvement Agreement ("IMPROVEMENT AGREEMENT") sets forth
the terms and conditions relating to construction of the initial tenant
improvements described in the Plans to be prepared and approved as provided
below (the "TENANT IMPROVEMENTS") in the Premises. Capitalized terms used but
not otherwise defined herein shall have the meanings set forth in the Lease (the
"LEASE") to which this Improvement Agreement is attached and forms a part.

1. Base Building Work. The "Base Building Work" described on SCHEDULE 1 to this
EXHIBIT C, if any, has been or will be performed by Landlord at Landlord's sole
cost and expense.

2. Plans and Specifications.

        A. Landlord and Tenant shall jointly retain the services of Devcon
Construction Incorporated (the "SPACE PLANNER") to prepare a detailed space plan
(the "SPACE PLAN") mutually satisfactory to Landlord and Tenant for the
construction of the Tenant Improvements in the Premises. Landlord and Tenant
shall approve or disapprove the Space Plan and any proposed revisions thereto in
writing within three (3) business days after receipt thereof, which approval
shall not be unreasonably withheld.

        B. Based on the approved Space Plan, Landlord and Tenant shall cause the
Space Planner to prepare detailed plans, specifications and working drawings for
the construction of the Tenant Improvements (the "PLANS"). Landlord and Tenant
shall diligently pursue the preparation of the Plans. Landlord and Tenant shall
approve or disapprove the Plans and any proposed revisions thereto, including
the estimated cost of the Tenant Improvements, in writing within three (3)
business days after receipt thereof. If Landlord or Tenant fails to approve or
disapprove the Space Plan or Plans or any revisions thereto within the time
limits specified herein, Landlord or Tenant shall be deemed to have approved the
same. Landlord and Tenant shall use diligent efforts to cause the final Plans
and the cost estimate to be prepared and approved no later than thirty (30) days
after the execution of the Lease.

        C. Notwithstanding Landlord's preparation, review and approval of the
Space Plan and the Plans and any revisions thereto, Landlord shall have no
responsibility or liability whatsoever for any errors or omissions contained in
the Space Plan or Plans, or to verify dimensions or conditions, or for the
quality, design or compliance with applicable Regulation of any improvements
described therein or constructed in accordance therewith. Landlord hereby
assigns to Tenant all warranties and guarantees by the Space Planner or the
contractor who constructs the Tenant Improvements relating to the Tenant
Improvements, and Tenant hereby waives all claims against Landlord relating to,
or arising out of the design or construction of, the Tenant Improvements.

3. Specifications for Standard Tenant Improvements.

        A. Specifications and quantities of standard building components which
will comprise and be used in the construction of the Tenant Improvements
("STANDARDS") are set forth in SCHEDULE 2 to this EXHIBIT C. As used herein,
"STANDARDS" or "BUILDING STANDARDS" shall mean the standards for a particular
item selected from time to time by Landlord for the Building, including those
set forth on SCHEDULE 2 of this EXHIBIT C, or such other standards of equal or
better quality as may be mutually agreed between Landlord and Tenant in writing.

        B. No deviations from the Standards are permitted without Landlord's
prior written consent which such consent shall not be unreasonably withheld,
delayed or conditioned.

4.      Tenant Improvement Cost.

        A. The cost of the Tenant Improvements shall be paid for by Tenant,
including, without limitation, the cost of: Standards; space plans and studies;
architectural and engineering fees incurred in connection with preparation of
the Plans; permits, approvals and other governmental fees; labor, material,
equipment and supplies; construction fees and other amounts payable to
contractors or subcontractors; taxes; off-site improvements; remediation and
preparation of the Premises for construction of the Tenant Improvements; taxes;
filing and recording fees; premiums for insurance and bonds; and all other costs
expended or to be expended in the construction of the Tenant Improvements,
including those costs incurred for construction of elements of the Tenant
Improvements in the Premises, which construction was performed by Landlord prior
to the execution of the Lease or for materials comprising the Tenant
Improvements which were purchased by Landlord prior to the execution of the
Lease.

Provided Tenant is not in default under the Lease, including this Improvement
Agreement, Landlord shall contribute a one-time tenant improvement allowance not
to exceed $25.00 per square foot times the rentable area of the Premises, plus a
credit for the Building core areas not fully constructed by Landlord (described
below), which credit and/or supply of pre-stocked fixtures and/or materials
shall be by mutual agreement of the parties ("TENANT IMPROVEMENT ALLOWANCE"), to
be credited by Landlord toward the cost of the initial Tenant Improvements. If
the cost of the Tenant Improvements exceeds the Tenant Improvement Allowance,
Tenant shall pay Landlord such excess cost within five (5) business days after
Landlord's notice to Tenant of such excess cost. If the cost of the Tenant
Improvements is less than the Tenant Improvement Allowance, Tenant shall receive
a credit towards Base Rent as follows: Within sixty (60) days after Tenant takes
possession of the entire Premises, Landlord shall deliver a statement to Tenant
detailing the actual Tenant Improvement costs spent by Landlord. For every whole
$1.00 per square foot of the Tenant Improvement Allowance that is unspent by
Landlord, Tenant shall receive a rent credit which shall be applied to Rent for
the next month of the Term. Notwithstanding the foregoing, in no event shall
said rent credit be greater than $3.00 per square foot of the rentable area of
the Premises.

The Building cores, not fully constructed by Landlord are generally described as

        C. If the cost of the Tenant Improvements increases after the Tenant's
approval of the Plans due to the requirements of any governmental agency or
applicable Regulation or any other reason, Tenant shall pay Landlord the amount
of such increase above the Tenant Improvement Allowance within five (5) business
days after notice from Landlord of such increase.

        D. If Tenant requests any change(s) in the Plans after approval of the
estimate of the cost of the Tenant Improvements and any such requested changes
are approved by Landlord in writing (which consent shall not be unreasonably
withheld, delayed or conditioned), Landlord shall advise Tenant promptly of any
cost increases and/or delays such approved change(s) will cause in the
construction of the Tenant Improvements. Tenant shall approve or disapprove any
or all such change(s) within three (3) business days after notice from Landlord
of such cost increases and/or delays. To the extent Tenant disapproves any such
cost increase and/or delay attributable thereto, Landlord shall have the right,
in its sole discretion, to disapprove Tenant's request for any changes to the
approved Plans. If the cost of the Tenant Improvements increases due to any
changes in the Plan(s) requested by Tenant, Tenant shall pay Landlord the amount
of such increase within five (5) business days after notice from Landlord of
such increase and Tenant's approval thereof in accordance with this Paragraph
4.D.

5. Construction of Tenant Improvements.

        A. Landlord and Tenant hereby approve Devcon Construction Incorporated
as the contractor, which Landlord and Tenant shall retain under a mutually
acceptable construction contract to be jointly administered by Landlord and
Tenant. Landlord shall pay the contractor directly for all contractors' invoices
in accordance with the construction contract specified herein. Upon Tenant's
approval of the Plans including the estimate of the cost of the Tenant
Improvements and Landlord's receipt of payment of any such estimated cost
exceeding the amount of the Tenant Improvement Allowance, Landlord and Tenant
shall cause Devcon Construction Incorporated to proceed to secure a building
permit and commence construction of the Tenant Improvements provided that
Landlord and Tenant shall cooperate together in executing permit applications
and performing other actions reasonably necessary to enable Landlord and Tenant
to obtain any required permits or certificates of occupancy; and provided
further that the Building has in Landlord's discretion reached the stage of
construction where it is appropriate to commence construction of the Tenant
Improvements in the Premises.

        B. Without limiting the provisions of Paragraph 35 of the Lease,
Landlord shall not be liable for any direct or indirect damages suffered by
Tenant as a result of delays in construction beyond Landlord's reasonable
control, including, but not limited to, delays due to strikes or unavailability
of materials or labor, or delays caused by Tenant (including delays by the Space
Planner, the contractor or anyone else performing services on behalf of Landlord
or Tenant).

        C. If any work is to be performed on the Premises solely by Tenant or
Tenant's contractor or agents:

               (1) Such work shall proceed upon Landlord's written approval
(which consent shall not be unreasonably withheld, delayed or conditioned) of
Tenant's contractor, public liability and property damage insurance carried by
Tenant's contractor, and detailed plans and specifications for such work, shall
be at Tenant's sole cost and expense and shall further be subject to the
provisions of Paragraphs 12 and 27 of the Lease.

               (2) All work shall be done in conformity with a valid building
permit when required, a copy of which shall be furnished to Landlord before such
work is commenced, and in any case, all such work shall be performed in
accordance with all applicable Regulations. Notwithstanding any failure by
Landlord to object to any such work, Landlord shall have no responsibility for
Tenant's failure to comply with all applicable Regulations.

               (3) If required by Landlord or any lender of Landlord, all
work by Tenant or Tenant's contractor or agents shall be done with union labor
in accordance with all union labor agreements applicable to the trades being
employed.

               (4) All work by Tenant or Tenant's contractor or agents shall
be scheduled through Landlord.

               (5) Tenant or Tenant's contractor or agents shall arrange for
necessary utility, hoisting and elevator service with Landlord's contractor and
shall pay such reasonable charges for such services as may be charged by
Tenant's or Landlord's contractor.

               (6) Tenant's entry to the Premises for any purpose, including,
without limitation, inspection or performance of Tenant construction by Tenant's
agents, prior to the date Tenant's obligation to pay rent commences shall be
subject to all the terms and conditions of the Lease except the payment of Rent.
Tenant's entry shall mean entry by Tenant, its officers, contractors, licensees,
agents, servants, employees, guests, invitees, or visitors.

               (7) Tenant shall promptly reimburse Landlord upon demand for
any reasonable expense actually incurred by the Landlord by reason of faulty
work done by Tenant or its contractors or by reason of any delays caused by such
work, or by reason of inadequate clean-up.

6. Completion and Rental Commencement Date.

        A. Tenant's obligation to pay Rent under the Lease shall commence on the
applicable date described in Paragraph 2 of the Lease, however:

               (1) If Tenant delays in preparing or approving the Space Plans
or the Plans, or fails to approve the estimate of the cost of the Tenant
Improvements or any other matter requiring Tenant's approval, or to pay the
excess cost of Tenant Improvements, in each case within the time limits
specified herein; or

               (2) If the construction period is extended because Tenant
requests any changes in construction, or modifies the approved Plans or if the
same do not comply with applicable Regulations; or

               (3) If Landlord is otherwise delayed in the construction of
the Tenant Improvements for any act or omission of or breach by Tenant or anyone
performing services on behalf of Tenant or on account of any work performed on
the Premises by Tenant or Tenant's contractors or agents, then the date
described in Paragraph 2 of the Lease shall be deemed to be accelerated by the
total number of days of Tenant delays described in (a) through (c) above (each,
a "TENANT DELAY"), calculated in accordance with the provisions of Paragraph 6.B
below.

        B. If the Term of the Lease has not already commenced pursuant to the
provisions of Paragraph 2 of the Lease and substantial completion of the Tenant
Improvements has been delayed on account of any Tenant Delays, then upon actual
substantial completion of the Tenant Improvements (as defined in Paragraph 2 of
the Lease), Landlord shall notify Tenant in writing of the date substantial
completion of the Tenant Improvements would have occurred but for such Tenant
Delays, and such date shall thereafter be deemed to be the Term Commencement
Date for all purposes under the Lease. Tenant shall pay to Landlord, within five
(5) business days after receipt of such written notice (which notice shall
include a summary of Tenant Delays), the per diem Base Rent times

                                       29
<PAGE>   59

the number of days between the date the Term Commencement Date would have
otherwise occurred but for the Tenant Delays (as determined by Landlord's
written documentation describing Tenant Delays), and the date of actual
substantial completion of the Tenant Improvements.

        C. Promptly after substantial completion of the Tenant Improvements,
Landlord shall give notice to Tenant and Tenant shall conduct an inspection of
the Premises with a representative of Landlord and develop with such
representative of Landlord a punchlist of items of the Tenant Improvements that
are not complete or that require corrections. Upon receipt of such punchlist,
Landlord shall proceed diligently to remedy such items at Landlord's cost and
expense provided such items are part of the Tenant Improvements to be
constructed by Landlord hereunder and are otherwise consistent with Landlord's
obligations under this Improvement Agreement and provided Tenant has fully paid
Landlord for the cost of the Tenant Improvements exceeding the Tenant
Improvement Allowance (with any dispute between Landlord and Tenant pertaining
thereto to be resolved by submitting to binding arbitration conducted and
determined in San Diego County according to the prevailing rules of the American
Arbitration Association for arbitration of commercial disputes). Substantial
completion shall not be delayed notwithstanding delivery of any such punchlist.

        D. A default under this Improvement Agreement shall constitute a default
under the Lease, and the parties shall be entitled to all rights and remedies
under the Lease in the event of a default hereunder by the other party
(notwithstanding that the Term thereof has not commenced).

        E. Without limiting the "as-is" provisions of the Lease, except for the
Tenant Improvements, if any, to be constructed by Landlord pursuant to this
Improvement Agreement, Tenant accepts the Premises in its "as-is" condition and
acknowledges that it has had an opportunity to inspect the Premises prior to
signing the Lease.

                                      LEASE

THIS LEASE is made as of the 2nd day of September, 1998, by and between Spieker
Properties, L.P., a California limited partnership (hereinafter called
"LANDLORD"), and Franklin Resources, Inc., a Delaware corporation (hereinafter
called "TENANT").

                                   1. PREMISES

    Landlord leases to Tenant and Tenant leases from Landlord, upon the terms
and conditions hereinafter set forth, those premises THAT WILL BE CONSTRUCTED
(the "PREMISES") outlined in red on EXHIBIT B and described in the Basic Lease
Information AND EXHIBIT G. The Premises shall comprise all of the buildings
(each individually a "BUILDING") and of a PORTION OF THE project (the
"PROJECT"), which may consist of more than one building and additional
facilities, as described in the Basic Lease Information AND EXHIBIT G. The
Building and Project are outlined in blue and green respectively on EXHIBIT B.
Landlord and Tenant acknowledge that, subject to the terms and provisions of
this Lease, physical changes may occur from time to time in the Premises,
Building or Project, and that the number of buildings and additional facilities
which constitute the Project may change from time to time, which may result in
an adjustment in Tenant's Proportionate Share, as defined in the Basic Lease
Information, as provided in Paragraph 7.A.

                      2. POSSESSION AND LEASE COMMENCEMENT

B. CONSTRUCTION OF IMPROVEMENTS. If this Lease pertains to a Building to be
constructed or improvements to be constructed within a Building, the provisions
of this Paragraph 2.B. shall apply in lieu of the provisions of Paragraph 2.A.
above and the term commencement date ("TERM COMMENCEMENT DATE") shall be the
earlier of the date on which: (1) Tenant takes possession of some or all of the
Premises for purposes of the commencement of the conduct of its business
therein; or (2) the improvements to be constructed or performed in the Premises
by Landlord (if any) shall have been substantially completed in accordance with
the Plans described on EXHIBIT C as certified by the architect, Devcon
Construction Incorporated, in writing to Tenant and Landlord (subject to mutual
approval by Landlord and Tenant), and Tenant's taking of possession of the
Premises or any part thereof for purposes of other than the installation of
telephone or data cabling or the installation of furniture or furniture systems
shall constitute Tenant's confirmation of substantial completion for all
purposes hereof (subject to the completion by Landlord of any punch list items
and any latent defects not visually discoverable by Tenant upon a reasonably
diligent inspection and which are identified in writing by Tenant within six (6)
months of the Tenant's occupancy of each Building), whether or not substantial
completion of other portions of the Building or Project shall have occurred. If
for any reason beyond Landlord's reasonable control Landlord cannot deliver
possession of the subject portion of the Premises to Tenant on the scheduled
Term Commencement Date, Landlord shall not be subject to any liability therefor,
nor shall Landlord be in default hereunder nor shall such failure affect the
validity of this Lease, and Tenant agrees to accept possession of other portions
of the Premises at such time as such improvements have been substantially
completed, which date shall then be deemed the Term Commencement Date; provided,
however, that if Landlord fails to tender possession of any portion of the
Premises, subject to Paragraph 35 of this Lease, within ninety (90) days of the
scheduled Term Commencement Date with respect to each Building, then Tenant,
upon not less than thirty (30) days prior written notice to Landlord shall have
the right to terminate this Lease with respect to each Building, unless within
such thirty (30) day period Landlord tenders possession of each Building in the
condition required by this Lease. Tenant shall not be liable for any Rent for
any period prior to the Term Commencement Date (but without affecting any
obligations of Tenant under any improvement agreement appended to this Lease).
In the event of any dispute as to substantial completion of work performed or
required to be performed by Landlord, the certificate of Landlord's architect or
general contractor shall be conclusive. Substantial completion shall have
occurred notwithstanding Tenant's submission of a punchlist to Landlord, which
Tenant shall submit, if at all, within seven (7) business days after the Term
Commencement Date or otherwise in accordance with any improvement agreement
appended to this Lease. Upon Landlord's request, Tenant shall promptly execute
and return to Landlord a "Start-Up Letter" in which Tenant shall agree, among
other things, to acceptance of the Premises (subject to any punchlist exceptions
according to Paragraph 6.C of EXHIBIT C) and to the determination of the Term
Commencement Date, in accordance with the terms of this Lease, but Tenant's
failure or refusal to do so shall not negate Tenant's acceptance of the Premises
or affect determination of the Term Commencement Date.

                                     3. TERM

    The term of this Lease (the "TERM") shall commence on the Term Commencement
Date and continue in full force and effect for the number of months specified as
the Length of Term in the Basic Lease Information or until this Lease is
terminated as otherwise provided herein. If the Term Commencement Date is a date
other than the first day of the calendar month, the Term shall be the number of
months of the Length of Term in addition to the remainder of the calendar month
following the Term Commencement Date.

                                     4. USE

A. GENERAL. Tenant shall use the Premises for the permitted use specified
in the Basic Lease Information ("PERMITTED USE") and for no other use or
purpose, without Landlord's consent, which consent shall not be unreasonably
withheld, delayed or conditioned. Tenant shall control Tenant's employees,
agents, customers, visitors, invitees, licensees, contractors, assignees and
subtenants (collectively, "TENANT'S PARTIES") in such a manner that Tenant and
Tenant's Parties cumulatively do not exceed the occupancy density (the
"OCCUPANCY DENSITY") or the parking density specified in the Basic Lease
Information (the "PARKING DENSITY") at any time. So long as Tenant is occupying
the Premises, Tenant and Tenant's Parties shall have the nonexclusive right to
use, without paying any fee or charge therefor, in common with other parties
occupying the Project, the parking areas, driveways and other common areas of
the

                                       4
<PAGE>   69

Building and Project, subject to the terms of this Lease and such rules and
regulations as Landlord may from time to time reasonably prescribe upon written
notice to Tenant. Landlord reserves the right to the extent it is commercially
reasonable to do so, upon reasonable prior written notice to Tenant, without
liability to Tenant, and without the same constituting an actual or constructive
eviction, to alter or modify the common areas from time to time, including the
location and configuration thereof, and the amenities and facilities which
Landlord may determine to provide from time to time, provided that no such
changes shall unreasonably affect access to or visibility of the Premises and
all such changes shall be consistent with the operation of comparable
first-class business parks in San Diego County, California.

B. LIMITATIONS. Tenant shall not permit any odors, smoke, dust, gas,
substances, noise or vibrations to emanate from the Premises or from any portion
of the common areas as a result of Tenant's or any Tenant's Party's use thereof,
nor take any action which would constitute a nuisance or would unreasonably
disturb, obstruct or endanger any other tenants or occupants of the Project or
elsewhere, or interfere with their use of their respective premises or common
areas. Storage outside the Premises of materials, vehicles or any other items is
prohibited. Tenant shall not use or allow the Premises to be used for any
unlawful purpose, nor shall Tenant cause or maintain or permit any nuisance in,
on or about the Premises. Tenant shall not commit or suffer the commission of
any waste in, on or about the Premises. Tenant shall not allow any sale by
auction upon the Premises, or place any loads upon the floors, walls or ceilings
which could endanger the structure, or place any harmful substances in the
drainage system of the Building or Project. No waste, materials or refuse shall
be dumped upon or permitted to remain outside the Premises except in trash
containers placed inside exterior enclosures designated for that purpose by
Landlord. Landlord shall not be responsible to Tenant for the non-compliance by
any other tenant or occupant of the Project with any of the above-referenced
rules or any other terms or provisions of such tenant's or occupant's lease or
other contract, provided Landlord shall administer compliance with such rules
and regulations in a nondiscriminatory manner.

C. COMPLIANCE WITH REGULATIONS. By entering the Premises for purposes of
the commencement of the conduct of Tenant's business, Tenant accepts the
Premises in the condition existing as of the date of such entry subject to the
completion by Landlord of any punchlist items and any latent defects as
described in Paragraph 2.B. of this Lease. Tenant shall at its sole cost and
expense strictly comply with all existing or future applicable municipal, state
and federal and other governmental statutes, rules, requirements, regulations,
laws and ordinances, including zoning ordinances and regulations, including the
MCAS Miramar Comprehensive Land Use Plan ("CLUP") attached hereto as Exhibit E
of this Lease, and covenants, easements and restrictions of record governing and
relating to the specific manner of Tenant's use, occupancy or possession of the
Premises, to Tenant's use of the common areas, or to the use, storage,
generation or disposal of Hazardous Materials (hereinafter defined)
(collectively "REGULATIONS"). Tenant shall at its sole cost and expense obtain
any and all licenses or permits necessary for Tenant's use of the Premises.
Tenant shall at its sole cost and expense promptly comply with the requirements
of any board of fire underwriters or other similar body now or hereafter
constituted. Tenant shall not do or permit anything to be done in, on, under or
about the Project or bring or keep anything which will in any way increase the
rate of any insurance upon the Premises, Building or Project or upon any
contents therein or cause a cancellation of said insurance or otherwise affect
said insurance in any manner. Tenant shall indemnify, defend (by counsel
reasonably acceptable to Landlord), protect and hold Landlord harmless from and
against any loss, cost, expense, damage, attorneys' fees or liability arising
out of the failure of Tenant to comply with any Regulation. Tenant's obligations
pursuant to the foregoing indemnity shall survive the expiration or earlier
termination of this Lease.

D. HAZARDOUS MATERIALS. As used in this Lease, "HAZARDOUS MATERIALS" shall
include, but not be limited to, hazardous, toxic and radioactive materials and
those substances defined as "hazardous substances," "hazardous materials,"
"hazardous wastes," "toxic substances," or other similar designations in any
Regulation. Tenant's Hazardous Materials Declaration is attached hereto as
EXHIBIT D. Tenant shall not cause, or allow any of Tenant's Parties to cause,
any Hazardous Materials to be handled, used, generated, stored, released or
disposed of in, on, under or about the Premises, the Building or the Project or
surrounding land or environment in violation of any Regulations. Tenant must
obtain Landlord's written consent prior to the introduction of any Hazardous
Materials onto the Project. Notwithstanding the foregoing, Tenant may handle,
store, use and dispose of products containing small quantities of Hazardous
Materials for "general office purposes" (such as toner for copiers) to the
extent customary and necessary for the Permitted Use of the Premises; provided
that Tenant shall always handle, store, use, and dispose of any such Hazardous
Materials in a safe and lawful manner and never allow such Hazardous Materials
to contaminate the Premises, Building, or Project or surrounding land or
environment. Tenant shall immediately notify Landlord in writing of any
Hazardous Materials' contamination of any portion of the Project of which Tenant
becomes aware, whether or not caused by Tenant. If, but only if, Landlord has a
reasonable basis to believe that Tenant has introduced any Hazardous Materials
onto the Premises, then Landlord shall have the right at all reasonable times to
inspect the Premises and to conduct tests and investigations to determine
whether Tenant is in compliance with the foregoing provisions, the reasonable
and actual costs of all such inspections, tests and investigations to be borne
by Tenant. Tenant shall indemnify, defend (by counsel reasonably acceptable to
Landlord), protect and hold Landlord harmless from and against any and all
claims, liabilities, losses, costs, loss of rents, liens, damages, injuries or
expenses (including attorneys' and consultants' fees and court costs), demands,
causes of action, or judgments directly or indirectly arising out of or related
to the use, generation, storage, release, or disposal of Hazardous Materials by
Tenant or any of Tenant's Parties in, on, under or about the Premises, the
Building or the Project or surrounding land or environment, which indemnity
shall include, without limitation, damages for personal or bodily injury,
property damage, damage to the environment or natural resources occurring on or
off the Premises, losses attributable to diminution in value or adverse effects
on marketability, the cost of any investigation, monitoring, government
oversight, repair, removal, remediation, restoration, abatement, and disposal,
and the preparation of any closure or other required plans, whether such action
is required or necessary prior to or following the expiration or earlier
termination of this Lease. Neither the consent by Landlord to the use,
generation, storage, release or disposal of Hazardous Materials nor the strict
compliance by Tenant with all laws pertaining to Hazardous Materials shall
excuse Tenant from Tenant's obligation of indemnification pursuant to this
Paragraph 4.D. Tenant's obligations pursuant to the foregoing indemnity shall
survive the expiration or earlier termination of this Lease.

                            5. RULES AND REGULATIONS

    Tenant shall faithfully observe and comply with the building rules and
regulations attached hereto as EXHIBIT A and any other rules and regulations and
any modifications or additions thereto which Landlord may from time to time
reasonably prescribe in writing for the purpose of maintaining the proper care,
cleanliness, safety, traffic flow and general order of the Premises or the
Building or Project. Tenant shall cause Tenant's Parties to comply with such
rules and regulations. Landlord shall not be responsible to Tenant for the
non-compliance by any other tenant or occupant of the Building or Project with
any of such rules and regulations, any other tenant's or occupant's lease or any
Regulations, provided Landlord shall administer compliance with such rules in a
nondiscriminatory manner.

                                  6. RENT

A. BASE RENT. Tenant shall pay to Landlord and Landlord shall receive,
without notice or demand throughout the Term, Base Rent as specified in the
Basic Lease Information, payable in monthly installments in advance on or before
the first day of each calendar month, in lawful money of the United States,
without deduction or offset whatsoever (except as otherwise expressly set forth
in this Lease), at the Remittance Address specified in the Basic Lease
Information or to such other place in the Continental United States as Landlord
may from time to time designate in writing. Base Rent for the first full two (2)
months of the Term shall be paid by Tenant upon Tenant's execution of this Lease
in accordance with Paragraph 38.D. of this Lease. If the obligation for payment
of Base Rent commences on a day other than

                                       5
<PAGE>   70

the first day of a month, then Base Rent shall be prorated and the prorated
installment shall be paid on the first day of the calendar month next succeeding
the Term Commencement Date. The Base Rent payable by Tenant hereunder is subject
to adjustment as provided elsewhere in this Lease, as applicable. As used
herein, the term "Base Rent" shall mean the Base Rent specified in the Basic
Lease Information as it may be so adjusted from time to time.

B. ADDITIONAL RENT. All monies other than Base Rent required to be paid by
Tenant hereunder, including, but not limited to, Tenant's Proportionate Share of
Operating Expenses, as specified in Paragraph 7 of this Lease, charges to be
paid by Tenant under Paragraph 15, the interest and late charge described in
Paragraphs 26.C. and D., and any monies spent by Landlord pursuant to Paragraph
30, shall be considered additional rent ("ADDITIONAL RENT"). "RENT" shall mean
Base Rent and Additional Rent.

                              7. OPERATING EXPENSES

A. OPERATING EXPENSES. In addition to the Base Rent required to be paid
hereunder, Tenant shall pay as Additional Rent, Tenant's Proportionate Share of
the Building and/or Project (as applicable), as defined in the Basic Lease
Information, of Operating Expenses (defined below) in the manner set forth
below. Tenant shall pay the applicable Tenant's Proportionate Share of each such
Operating Expenses. Landlord and Tenant acknowledge that if the number of
buildings which constitute the Project increases or decreases, or if physical
changes are made to the Building or Project or the configuration of any thereof,
Landlord may at its discretion reasonably adjust Tenant's Proportionate Share of
the Building or Project to reflect the change. Landlord's determination of
Tenant's Proportionate Share of the Project shall be conclusive so long as it is
reasonably and consistently applied. "OPERATING EXPENSES" shall mean all
expenses and costs of every kind and nature which Landlord shall reasonably pay
or become obligated to pay, because of or in connection with the management,
maintenance, repair, preservation, replacement and operation of the Building or
Project and its supporting facilities and such additional facilities now and in
subsequent years as may be determined by Landlord to be necessary or desirable
to the Building and/or Project (as determined in a reasonable manner) other than
those expenses and costs which are specifically attributable to Tenant or which
are expressly made the financial responsibility of Landlord or specific tenants
of the Building or Project pursuant to this Lease. Operating Expenses shall
include, but are not limited to, the following:

        (1) TAXES. All real property taxes and general assessments, possessory
        interest taxes, sales taxes, personal property taxes, business or
        license taxes or fees, gross receipts taxes, service payments in lieu of
        such taxes or fees, annual or periodic license or use fees, excises,
        transit charges imposed generally and not in connection with the initial
        development of the Project, and other impositions, general and special,
        ordinary and extraordinary, unforeseen as well as foreseen, of any kind
        (including fees "in-lieu" of any such tax or assessment) which are now
        or hereafter assessed, levied, charged, confirmed, or imposed by any
        public authority upon the Building or Project, its operations or the
        Rent (or any portion or component thereof), or any tax, assessment or
        fee imposed in substitution, partially or totally, of any of the above.
        Operating Expenses shall also include any taxes, assessments,
        reassessments, or other fees or impositions with respect to the
        development, leasing, management, maintenance, alteration, repair, use
        or occupancy by Tenant of the Premises, Building or Project or any
        portion thereof, including, without limitation, by or for Tenant, and
        all increases therein or reassessments thereof whether the increases or
        reassessments result from increased rate and/or valuation (whether upon
        a transfer of the Building or Project or any portion thereof or any
        interest therein or for any other reason). Operating Expenses shall not
        include inheritance or estate taxes imposed upon or assessed against the
        interest of any person in the Project, or taxes computed upon the basis
        of the net income of any owners of any interest in the Project. If it
        shall not be lawful for Tenant to reimburse Landlord for all or any part
        of such taxes, the monthly rental payable to Landlord under this Lease
        shall be revised to net Landlord the same net rental after imposition of
        any such taxes by Landlord as would have been payable to Landlord prior
        to the payment of any such taxes. Notwithstanding anything set forth in
        this Lease to the contrary, in no event shall "Taxes" include any fees,
        costs or exactions incurred by Landlord in connection with obtaining the
        right to develop the Project (exclusive of Tenant Improvements),
        including, but not limited to, any fees for schools, parks, traffic,
        sewer and fire protection, or any special assessments used to finance
        any portion of the Project, including any off-site roadway or utility
        facilities.

        (2) INSURANCE. All insurance premiums and costs, including, but not
        limited to, any deductible amounts, premiums and other costs of
        insurance reasonably and actually incurred by Landlord, including for
        the insurance coverage set forth in Paragraph 8.A. herein. In an event
        wherein a deductible may be greater than Fifty Thousand Dollars
        ($50,000.00) said deductible amount shall be amortized over the greater
        of (i) the remaining Term of this Lease or (ii) three (3) years.

        (3) COMMON AREA MAINTENANCE.

               (a) Repairs, replacements, and general maintenance of and for the
               Building and Project and public and common areas and facilities
               of and comprising the Building and Project, including, but not
               limited to, the roof and roof membrane, elevators, mechanical
               rooms, alarm systems, pest extermination, landscaped areas,
               parking and service areas, driveways, sidewalks, truck staging
               areas, rail spur areas, fire sprinkler systems, sanitary and
               storm sewer lines, utility services, heating/ventilation/air
               conditioning systems, electrical, mechanical or other systems,
               telephone equipment and wiring servicing, plumbing, lighting, and
               any other items or areas which affect the operation or appearance
               of the Building or Project, which determination shall be at
               Landlord's discretion, except for: those items expressly made the
               financial responsibility of Landlord pursuant to Paragraph 10
               hereof; those items to the extent paid for by the proceeds of
               insurance or which are covered under warranties of the
               contractor, manufacturer or supplier thereof; and those items
               attributable solely or jointly to specific tenants of the
               Building or Project.

               (b) Repairs, replacements, and general maintenance shall include
               the cost of any capital improvements made to or capital assets
               acquired for the Project or Building that are reasonably intended
               to reduce any other Operating Expenses, including future repair
               work not covered by applicable warranties, are reasonably
               necessary for the health and safety of the occupants of the
               Building or Project, or are required to comply with any change in
               Regulation not applicable to the Building as of the Term
               Commencement Date, such costs or allocable portions thereof to be
               amortized over such reasonable period as Landlord shall
               determine, together with interest on the unamortized balance at
               the publicly announced "prime rate" charged by Wells Fargo Bank,
               N.A. (San Francisco) or its successor at the time such
               improvements or capital assets are constructed or acquired, plus
               two (2) percentage points, or in the absence of such prime rate,
               then at the U.S. Treasury six-month market note (or bond, if so
               designated) rate as published by any national financial
               publication selected by Landlord, plus four (4) percentage
               points, but in no event more than the maximum rate permitted by
               law, plus reasonable financing charges. Landlord shall be
               responsible, at its sole cost and expense, for performing all
               work to the Buildings (exclusive of Tenant Improvements) or the
               common areas necessary to cause the Project to conform to
               regulations applicable as of the Term Commencement Date.

               (c) Payment under or for any easement, license, permit, operating
               agreement, declaration, restrictive covenant or instrument
               relating to the Building or Project.

               (d) All expenses and rental related to services and costs of
               supplies, materials and equipment used in operating, managing and
               maintaining the Premises, Building and Project, the equipment
               therein and the adjacent sidewalks,

               driveways, parking and service areas, including, without
               limitation, expenses related to service agreements regarding
               security, fire and other alarm systems, janitorial services to
               the extent not addressed in Paragraph 11 hereof, window cleaning,
               elevator maintenance, Building exterior maintenance, landscaping
               and expenses related to the administration, and operation of the
               Project, including without limitation salaries, wages and
               benefits.

               (e) The cost of supplying any services and utilities which
               benefit all or a portion of the Premises, Building or Project to
               the extent not addressed in Paragraph 15 hereof.

               (f) Reasonable legal expenses and the cost of audits by certified
               public accountants; provided, however, that legal expenses
               chargeable as Operating Expenses shall not include the cost of
               negotiating leases, collecting rents, evicting tenants nor shall
               it include costs incurred in legal proceedings with or against
               any tenant or to enforce the provisions of any lease.

               (g) An administrative and accounting cost recovery fee equal to
               twenty percent (20%) of the sum of the Project's Operating
               Expenses.

If the rentable area of the Building and/or Project is not fully occupied during
any fiscal year of the Term as determined by Landlord, an adjustment may be made
in Landlord's discretion in computing the Operating Expenses for such year so
that Tenant pays an equitable portion of all variable items (e.g., utilities,
janitorial services and other component expenses that are affected by variations
in occupancy levels) of Operating Expenses, as reasonably determined by
Landlord; provided, however, that in no event shall Landlord be entitled to
collect in excess of one hundred percent (100%) of the total Operating Expenses
from all of the tenants in the Building or Project, as the case may be.

Operating Expenses shall not include the following:

        (i)     costs incurred in connection with the original construction of
                the Building or the Project;

        (ii)    interest, principal, late charges, default fees, prepayment
                penalties or premiums on any debt owed by Landlord, including
                any mortgage debt;

        (iii)   costs of correcting defects in or inadequacy of the initial
                design or construction of the Building;

        (iv)    expenses directly resulting from the gross negligence of the
                Landlord, its agents, servants or employees, or another tenant;

        (v)     legal fees, space planners' fees, real estate brokers' leasing
                commissions and advertising expenses incurred in connection with
                the original development or original leasing of the Project or
                future leasing of the Project;

        (vi)    costs for which Landlord is reimbursed by any tenant or occupant
                of the Project or by insurance by its carrier or any tenant's
                carrier or by anyone else;

        (vii)   any bad debt loss, rent loss, or reserves for bad debts or rent
                loss;

        (viii)  expenses of extraordinary services provided to other tenants in
                the Project which are made available to Tenant at costs or for
                which Tenant is separately charged;

        (ix)    costs associated with the operation of the business of the
                partnership which constitutes Landlord, as the same are
                distinguished from the costs of operation of the Project,
                including partnership accounting and legal matters, costs of
                defending any lawsuits with any mortgagee (except as the actions
                of Tenant may be the issue), costs of selling, syndicating,
                financing, mortgaging or hypothecating any of Landlord's
                interest in the Project, or any portions thereof, costs
                (including attorney fees and costs of settlement, judgments and
                payments in lieu thereof) arising from claims, disputes or
                potential disputes in connection with potential or actual
                claims, litigation or arbitrations respecting Landlord and/or
                the Project and/or the site upon which the Project is situated;

        (x)     the wages and benefits of any employee who does not devote
                substantially all of his or her time to the Project unless such
                wages and benefits are prorated to reflect time spent on
                operating and managing the Project vis-a-vis time spent on
                matters unrelated to operating and managing the Project;

        (xi)    fines, penalties and interest;

        (xii)   amounts paid as ground rental by Landlord;

        (xiii)  capital expenditures to comply with applicable laws including
                costs arising from the presence of Hazardous Materials in or
                about the Project, or the site upon which the Project is
                situated, which are not caused by or connected with Tenant;

        (xiv)   costs incurred by Landlord with respect to goods and services
                (including utilities sold or supplied to tenants and occupants
                of the Project) to the extent that Landlord would be entitled to
                reimbursement for such costs if incurred by Tenant pursuant to
                this Lease;

        (xv)    costs, including permit, license and inspection costs, incurred
                with respect to the installation of tenant improvements made for
                new tenants in the Project or incurred in renovating or
                otherwise improving, decorating, painting or redecorating vacant
                space for tenants or other occupants of the Project;

        (xvi)   costs incurred by Landlord for alterations which are considered
                capital improvements and replacements under generally accepted
                accounting principles, consistently applied, except as expressly
                allowed for in Paragraph 7.A.(3)(b) of this Lease;

        (xvii)  costs of a capital nature, including without limitation capital
                improvements, capital repairs, capital equipment and capital
                tools, all as determined in accordance with generally accepted
                accounting principles, consistently applied, except as expressly
                allowed for in Paragraph 7.A.(3)(b) of this Lease;

        (xviii) expenses in connection with services or other benefits which
                are not provided to Tenant or for which Tenant is charged
                directly but which are provided to another tenant or occupant of
                the Project without a separate charge;

                                       7
<PAGE>   72

        (xix)    costs paid to Landlord or to affiliates of Landlord for
                 services in the Project to the extent the same exceed or would
                 exceed the costs for such services if rendered by unaffiliated
                 third parties on a competitive basis;

        (xx)     rentals and other related expenses incurred in leasing air
                 conditioning systems, elevators or other equipment ordinarily
                 considered to be of a capital nature if purchased, except
                 equipment not affixed to the Project which is used in providing
                 janitorial or similar services;

        (xxi)    all items and services for which Tenant or any other tenant in
                 the Project reimburses Landlord or which Landlord provides
                 selectively to one or more tenants (other than Tenant) without
                 reimbursement;

        (xxii)   electric power costs for which any tenant directly contracts

        (xxvi)   costs for which Landlord has been compensated by an
                 administrative fee;

        (xxvii)  costs arising from the gross negligence of Landlord or its
                 agents, or any vendors, contractors or providers of materials
                 or services selected, hired or engaged by Landlord or its

        (xxviii) Landlord's general corporate overhead and general and

                 any tenant of the terms and conditions of any lease of space in
                 the Project.

        Notwithstanding anything herein to the contrary, in any instance
wherein Landlord, in Landlord's reasonable discretion, deems Tenant to be
responsible for any amounts greater than Tenant's Proportionate Share, Landlord
shall have the right to reasonably allocate costs in any manner Landlord
reasonably deems appropriate.

        The above enumeration of services and facilities shall not be deemed to
impose an obligation on Landlord to make available or provide such services or
facilities except to the extent if any that Landlord has specifically agreed
elsewhere in this Lease to make the same available or provide the same; provided
that Landlord shall operate and maintain the Project in a manner reasonably
comparable to other comparable first-class business park projects in San Diego
County. Without limiting the generality of the foregoing, Tenant acknowledges
and agrees that it shall be responsible for providing adequate security for its
use of the Premises, the Building and the Project and that Landlord shall have
no obligation or liability with respect thereto, except to the extent if any
that Landlord has specifically agreed elsewhere in this Lease to provide the
same.

B. PAYMENT OF ESTIMATED OPERATING EXPENSES. "ESTIMATED OPERATING EXPENSES" for
any particular year shall mean Landlord's reasonable estimate of the Operating
Expenses for such fiscal year made with respect to such fiscal year as
hereinafter provided. Landlord shall have the right from time to time to revise
its fiscal year and interim accounting periods so long as the periods as so
revised are reconciled with prior periods in a reasonable manner. During the
last month of each fiscal year during the Term, or as soon thereafter as
practicable, but in any event by April 30 of the following year, Landlord shall
give Tenant written notice of the Estimated Operating Expenses for the ensuing
fiscal year. Tenant shall pay Tenant's Proportionate Share of the Estimated
Operating Expenses with installments of Base Rent for the fiscal year to which
the Estimated Operating Expenses applies in monthly installments on the first
day of each calendar month during such year, in advance. Such payment shall be
construed to be Additional Rent for all purposes hereunder. If at any time
during the course of the fiscal year, Landlord determines that Operating
Expenses are projected to vary from the then Estimated Operating Expenses by
more than five percent (5%), Landlord may, by written notice to Tenant stating
with specificity the basis for such readjustment, revise the Estimated Operating
Expenses for the balance of such fiscal year, and Tenant's monthly installments
for the remainder of such year shall be adjusted so that by the end of such
fiscal year Tenant has paid to Landlord Tenant's Proportionate Share of the
revised Estimated Operating Expenses for such year, such revised installment
amounts to be Additional Rent for all purposes hereunder.

C. COMPUTATION OF OPERATING EXPENSE ADJUSTMENT. "OPERATING EXPENSE ADJUSTMENT"
shall mean the difference between Estimated Operating Expenses and actual
Operating Expenses for any fiscal year determined as hereinafter provided.
Within one hundred twenty (120) days after the end of each fiscal year, or as
soon thereafter as practicable but in any event by June 30 of such year,
Landlord shall deliver to Tenant a statement of actual Operating Expenses for
the fiscal year just ended, accompanied by a computation of Operating Expense
Adjustment. If such statement shows that Tenant's payment based upon Estimated
Operating Expenses is less than Tenant's Proportionate Share of Operating
Expenses, then Tenant shall pay to Landlord the difference within thirty (30)
days after receipt of such statement, such payment to constitute Additional Rent
for all purposes hereunder. If such statement shows that Tenant's payments of
Estimated Operating Expenses exceed Tenant's Proportionate Share of Operating
Expenses, then (provided that Tenant is not in default under this Lease)
Landlord shall pay to Tenant the difference within thirty (30) days after
delivery of such statement to Tenant. If this Lease has been terminated or the
Term hereof has expired prior to the date of such statement, then the Operating
Expense Adjustment shall be paid by the appropriate party within thirty (30)
days after the date of delivery of the statement. Should this Lease commence or
terminate at any time other than the first day of the fiscal year, Tenant's
Proportionate Share of the Operating Expense Adjustment shall be prorated based
on a month of 30 days and the number of calendar months during such fiscal year
that this Lease is in effect. Notwithstanding anything to the contrary contained
in Paragraph 7.A or 7.B, Landlord's failure to provide any notices or statements
within the time periods specified in those paragraphs shall in no way excuse
Tenant from its obligation to pay Tenant's Proportionate Share of Operating
Expenses.

D. NET LEASE. This shall be a triple net Lease and Base Rent shall be paid to
Landlord absolutely net of all costs and expenses, except as specifically
provided to the contrary in this Lease. The provisions for payment of Operating
Expenses and the Operating Expense Adjustment are intended to pass on to Tenant
and reimburse Landlord for all costs and expenses of the nature described in
Paragraph 7.A. incurred in connection with the management, maintenance,
repair, preservation, replacement and operation of the Building and/or Project
and its supporting facilities and such additional facilities now and in
subsequent years as may be determined by Landlord to be necessary or desirable
to the Building and/or Project.

E. TENANT AUDIT. If Tenant shall dispute the amount set forth in any statement
provided by Landlord under Paragraph 7.B. or 7.C. above, Tenant shall have the
right, not later than six (6) months following receipt of such statement and
upon the condition that Tenant shall first deposit with Landlord the full amount
in dispute, to cause Landlord's books and records with respect to Operating
Expenses for such fiscal year to be audited by certified public accountants
selected by Tenant and subject to Landlord's reasonable right of approval. The
Operating Expense Adjustment shall be appropriately adjusted on the basis of
such audit. If such audit discloses a liability for a refund in excess of five
percent (5%) of Tenant's Proportionate Share of the Operating

                                       8
<PAGE>   73

Expenses previously reported, the cost of such audit shall be borne by Landlord;
otherwise the cost of such audit shall be paid by Tenant. If Tenant shall not
request an audit in accordance with the provisions of this Paragraph 7.E. within
six (6) months after receipt of Landlord's statement provided pursuant to
Paragraph 7.B. or 7.C., such statement shall be final and binding for all
purposes hereof, absent manifest error.

F. CALCULATION OF OPERATING EXPENSES. Operating Expenses shall be calculated and
determined in accordance with the following general principles:

        (1)  RECOVERY LIMITED TO ACTUAL COSTS. Landlord shall not recover the
             cost of any item more than once.

        (2)  ARM'S LENGTH. All services rendered to and materials supplied to
             the Project shall be rendered or supplied at a cost comparable to
             those charged in arm's length transactions for similar services or
             materials rendered or supplied for similar purposes to comparable
             buildings in San Diego County.

        (3)  REIMBURSEMENTS. All discounts, reimbursements, rebates, refunds or
             credits (collectively, "Reimbursements") attributable to Operating
             Expenses received by Landlord in a particular year shall be
             deducted from Operating Expenses in the year the same are received;
             provided, however, if a particular Reimbursement exceeds Fifty
             Thousand Dollars ($50,000.00) and applies to a prior year, such
             Reimbursement shall be applied to such prior year (and Tenant's
             Proportionate Share thereof shall be promptly refunded).

        (4)  NON-PROJECT EXCLUSIVE EXPENSES. Whenever expenses are paid or
             incurred by Landlord as a result of activities that are not
             exclusively rendered to the Project, only that portion that can be
             reasonably allocated to the Project shall be included within
             Operating Expenses.

        (5)  INSTALLMENTS. All assessments and premiums of Operating Expenses
             which can be paid or incurred by Landlord in annual installments
             shall be paid by Landlord in the maximum number of annual
             installments permitted by law and shall not be included as
             Operating Expenses except in the calculation year in which the
             installments are actually paid; provided, however, that if the
             then-prevailing practice in other comparable buildings is to pay
             such assessments or premiums on an earlier basis and Landlord shall
             pay the same on such basis, such assessments or premiums shall be
             included in Operating Expenses as paid by Landlord.

        (6)  REASONABLENESS. Landlord shall use its reasonable efforts to
             operate and maintain the Project in an economically reasonable
             manner.

                        8. INSURANCE AND INDEMNIFICATION

A. LANDLORD'S INSURANCE. All insurance maintained by Landlord shall be for the
sole benefit of Landlord and under Landlord's sole control.

        (1) PROPERTY INSURANCE. Landlord agrees to maintain property insurance
        insuring the Building against damage or destruction due to risk
        including fire, vandalism, and malicious mischief in an amount not less
        than the replacement cost thereof, in the form and with deductibles and
        endorsements as selected by Landlord. At its election, Landlord may
        instead (but shall have no obligation to) obtain "All Risk" coverage,
        and may also obtain earthquake, pollution, and/or flood insurance in
        amounts selected by Landlord.

        (2) OPTIONAL INSURANCE. Landlord, at Landlord's option, may also (but
        shall have no obligation to) carry insurance against loss of rent, in an
        amount equal to the amount of Base Rent and Additional Rent that
        Landlord could be required to abate to all Building tenants in the event
        of condemnation or casualty damage for a period of twelve (12) months.
        Landlord may also (but shall have no obligation to) carry such other
        insurance as Landlord may reasonably deem prudent or advisable,
        including, without limitation, liability insurance in such amounts and
        on such terms as Landlord shall determine. If and when Spieker
        Properties, L.P or its successor by merger or acquisition, is no longer
        the "Landlord" under this Lease, then at all times Landlord shall carry
        a policy of Commercial General Liability Insurance with limits of
        liability of no less than Three Million Dollars ($3,000,000.00).
        Landlord shall not be obligated to insure, and shall have no
        responsibility whatsoever for any damage to, any furniture, machinery,
        goods, inventory or supplies, or other personal property or fixtures
        which Tenant may keep or maintain in the Premises, or any leasehold
        improvements, additions or alterations within the Premises except where
        such damage arises from the active negligence or willful misconduct of
        Landlord, its employees, agents, or contractors.

B. TENANT'S INSURANCE.

        So long as Franklin Resources, Inc. is "Tenant" under this Lease, the
        coverages Tenant is required to maintain under this Lease may be
        maintained under a program of Tenant's self-insurance or under policies
        that include self-insured retentions or deductibles that are typically
        carried by similarly situated tenants. Prior to any implementation of
        Tenant's self-insurance program, Tenant shall in writing advise Landlord
        of the self-insured retentions, or deductibles.

        (1) PROPERTY INSURANCE. Tenant shall procure at Tenant's sole cost and
        expense and keep in effect from the date of this Lease and at all times
        until the end of the Term, insurance on all personal property and
        fixtures of Tenant and all improvements, additions or alterations made
        by or for Tenant to the Premises on an "All Risk" basis, insuring such
        property for the full replacement value of such property.

        (2) LIABILITY INSURANCE. Tenant shall procure at Tenant's sole cost and
        expense and keep in effect from the date of this Lease and at all times
        until the end of the Term Commercial General Liability insurance
        covering bodily injury and property damage liability occurring in or
        about the Premises or arising out of the use and occupancy of the
        Premises and the Project, and any part of either, and any areas adjacent
        thereto, and the business operated by Tenant or by any other occupant of
        the Premises. Such insurance shall include contractual liability
        coverage insuring all of Tenant's indemnity obligations under this
        Lease. Such coverage shall have a minimum combined single limit of
        liability of at least Two Million Dollars ($2,000,000.00), and a minimum
        general aggregate limit of Three Million Dollars ($3,000,000.00), with
        an "Additional Insured - Managers or Lessors of Premises Endorsement"
        and the "Amendment of the Pollution Exclusion Endorsement." All such
        policies shall be written to apply to all bodily injury (including
        death), property damage or loss, personal and advertising injury and
        other covered loss, however occasioned, occurring during the policy
        term, shall be endorsed to add Landlord and any party holding an
        interest to which this Lease may be subordinated as an additional
        insured, and shall provide that such coverage shall be "PRIMARY" and
        non-contributing with any insurance maintained by Landlord, which shall
        be excess insurance only. Such coverage shall also contain endorsements
        including employees as additional insureds if not covered by Tenant's
        Commercial General Liability Insurance. All such insurance shall provide
        for the severability of interests of insureds; and shall be written on
        an "OCCURRENCE" basis, which shall afford coverage for all claims based
        on acts, omissions, injury and damage, which occurred or arose (or the
        onset of which occurred or arose) in whole or in part during the policy
        period.

                                       9
<PAGE>   74

        (3) WORKERS' COMPENSATION AND EMPLOYERS' LIABILITY INSURANCE. Tenant
        shall carry Workers' Compensation Insurance as required by any
        Regulation, throughout the Term at Tenant's sole cost and expense. To
        the extent required by any Regulation, Tenant shall also carry
        Employers' Liability Insurance in amounts not less than One Million
        Dollars ($1,000,000) each accident for bodily injury by accident; One
        Million Dollars ($1,000,000) policy limit for bodily injury by disease;
        and One Million Dollars ($1,000,000) each employee for bodily injury by
        disease, throughout the Term at Tenant's sole cost and expense.

        (4) COMMERCIAL AUTO LIABILITY INSURANCE. Tenant shall procure at
        Tenant's sole cost and expense and keep in effect from the date of this
        Lease and at all times until the end of the Term commercial auto
        liability insurance with a combined limit of not less than One Million
        Dollars ($1,000,000) for bodily injury and property damage for each
        accident. Such insurance shall cover liability relating to any auto
        (including owned, hired and non-owned autos).

        (5) GENERAL INSURANCE REQUIREMENTS. All coverages described in this
        Paragraph 8.B. shall be endorsed to (i) provide Landlord with thirty
        (30) days' notice of cancellation or material change in terms; and (ii)
        waive all rights of subrogation by the insurance carrier against
        Landlord. If at any time during the Term the amount or coverage of
        insurance which Tenant is required to carry under this Paragraph 8.B.
        is, in Landlord's reasonable judgment, materially less than the amount
        or type of insurance coverage typically carried by owners or tenants of
        properties located in the general area in which the Premises are located
        which are similar to and operated for similar purposes as the Premises
        or if Tenant's use of the Premises should change with or without
        Landlord's consent, Landlord shall have the right to require Tenant to
        increase the amount or change the types of insurance coverage required
        under this Paragraph 8.B. All insurance policies required to be carried
        by Tenant under this Lease shall be written by companies rated A VII or
        better in "Best's Insurance Guide" and authorized to do business in the
        State of California. Should Franklin Resources, Inc. or its successor by
        merger or acquisition, no longer be "Tenant" under this Lease, then
        deductible amounts under all insurance policies required to be carried
        by Tenant under this Lease shall not exceed Five Thousand Dollars
        ($5,000.00) per occurrence. Tenant shall deliver to Landlord on or
        before the Term Commencement Date, and thereafter at least thirty (30)
        days before the expiration dates of the expired policies, or a
        certificate evidencing the same issued by the insurer thereunder; and,
        if Tenant shall fail to procure such insurance, or to deliver such
        certificates, Landlord may, at Landlord's option and in addition to
        Landlord's other remedies in the event of a default by Tenant hereunder,
        procure the same for the account of Tenant, and the cost thereof shall
        be paid to Landlord as Additional Rent.

C. INDEMNIFICATION. Tenant shall indemnify, defend by counsel reasonably
acceptable to Landlord, protect and hold Landlord harmless from and against any
and all claims, liabilities, losses, costs, loss of rents, liens, damages,
injuries or expenses, including reasonable attorneys' and consultants' fees and
court costs, demands, causes of action, or judgments, directly or indirectly
arising out of or related to: (1) claims of injury to or death of persons or
damage to property occurring or resulting directly or indirectly from the use or
occupancy of the Premises, Building or Project by Tenant or Tenant's Parties, or
from activities or failures to act of Tenant or Tenant's Parties; (2) claims
arising from work or labor performed, or for materials or supplies furnished to
or at the request of Tenant in connection with performance of any work done for
the account of Tenant within the Premises or Project; (3) claims arising from
any breach or default on the part of Tenant in the performance of any covenant
contained in this Lease; and (4) claims arising from the negligence or
intentional acts or omissions of Tenant or Tenant's Parties. The foregoing
indemnity by Tenant shall not be applicable to claims to the extent arising from
the active negligence or willful misconduct of Landlord. Landlord shall not be
liable to Tenant and Tenant hereby waives all claims against Landlord for any
injury or damage to any person or property in or about the Premises, Building or
Project by or from any cause whatsoever (other than Landlord's active negligence
or willful misconduct) and, without limiting the generality of the foregoing,
whether caused by water leakage of any character from the roof, walls, basement
or other portion of the Premises, Building or Project, or caused by gas, fire,
oil or electricity in, on or about the Premises, Building or Project. Landlord
shall indemnify, defend by counsel reasonably acceptable to Tenant, protect and
hold Tenant harmless from and against any and all claims, liabilities, losses,
costs, liens, damages, injuries or expenses, including reasonable attorneys'
fees and consultants' fees and court costs, demands, causes of action or
judgments directly or indirectly arising from the active negligence or willful
misconduct of Landlord or its employees, agents or contractors. The provisions
of this Paragraph shall COMMENCE FROM THE DATE OF THIS LEASE AND survive the
expiration or earlier termination of this Lease.

                            9. WAIVER OF SUBROGATION

    To the extent permitted by law and without affecting the coverage provided
by insurance to be maintained hereunder or any other rights or remedies,
Landlord and Tenant each waive any right to recover against the other for: (a)
damages for injury to or death of persons; (b) damages to property, including
personal property; (c) damages to the Premises or any part thereof; and (d)
claims arising by reason of the foregoing due to hazards covered by insurance
maintained or required to be maintained pursuant to this Lease to the extent of
proceeds recovered therefrom, or proceeds which would have been recoverable
therefrom in the case of the failure of any party to maintain any insurance
coverage required to be maintained by such party pursuant to this Lease. This
provision is intended to waive fully, any rights and/or claims arising by reason
of the foregoing, but only to the extent that any of the foregoing damages
and/or claims referred to above are covered or would be covered, and only to the
extent of such coverage, by insurance actually carried or required to be
maintained pursuant to this Lease by either Landlord or Tenant. This provision
is also intended to waive fully, and for the benefit of each party, any rights
and/or claims which might give rise to a right of subrogation on any insurance
carrier. Subject to all qualifications of this Paragraph 9, Landlord waives its
rights as specified in this Paragraph 9 with respect to any subtenant that it
has approved pursuant to Paragraph 21 but only in exchange for the written
waiver of such rights to be given by such subtenant to Landlord upon such
subtenant taking possession of the Premises or a portion thereof. Each party
shall cause each insurance policy obtained by it to provide that the insurance
company waives all right of recovery by way of subrogation against either party
in connection with any damage covered by any policy.

                     10. LANDLORD'S REPAIRS AND MAINTENANCE

    Landlord shall at Landlord's expense maintain in first-class condition and
repair, reasonable wear and tear excepted, the structural soundness of the roof,
foundations, and exterior walls of the Building. The term "exterior walls" as
used herein shall not include windows, glass or plate glass, doors, dock bumpers
or dock plates, special store fronts or office entries. Landlord shall perform
on behalf of Tenant and other tenants of the Project the maintenance of the
public and common areas of the Project including, but not limited to, the
landscaped areas, parking areas, driveways, sanitary and storm sewer lines,
utilities services, HVAC systems, electric equipment (excluding Tenant's
emergency electric generator(s) described in Paragraph 38 H. hereof) servicing
the Building, exterior lighting, Project trash removal services, and anything
which affects the operation and exterior appearance of the Project, which
determination shall be at Landlord's reasonable discretion. Any damage caused by
or repairs necessitated by any negligence or act of Tenant or Tenant's Parties
may be repaired by Landlord at Landlord's option and Tenant's expense. Tenant
shall immediately give Landlord written notice of any defect or need of repairs
in such components of the Building for which Landlord is responsible, after
which Landlord shall have a reasonable opportunity and the right to enter the
Premises at all reasonable times to repair same. Landlord's liability with
respect to any defects, repairs, or maintenance for which Landlord is
responsible under any of the provisions of this Lease shall be limited to the
cost of such repairs or maintenance, and there shall be no abatement of rent and
no liability of Landlord by reason of any injury to or interference with
Tenant's business arising from the making of repairs, alterations or
improvements in or to any portion of the Premises, the Building or the Project
or to fixtures, appurtenances or equipment in the Building, except as provided
in Paragraph 24 or anywhere else in this Lease. By taking possession of the
Premises, Tenant, subject to Paragraph 2.B. of this Lease, accepts them "as is,"
as being in good order, condition

                                       10
<PAGE>   75

and repair and the condition in which Landlord is obligated to deliver them and
suitable for the Permitted Use and Tenant's intended operations in the Premises,
whether or not any notice of acceptance is given.

                      11. TENANT'S REPAIRS AND MAINTENANCE

    Tenant shall at all times during the Term at Tenant's expense maintain all
interior non-structural parts of the Premises and such portions of the Building
as are within the exclusive control of Tenant in a first-class, good, clean and
secure condition and promptly make all necessary repairs and replacements, as
reasonably determined by Landlord, including but not limited to, all windows,
glass, doors, walls, including demising walls, and wall finishes, floors and
floor covering, ceiling insulation, truck doors, hardware, plumbing work and
fixtures, downspouts, entries, skylights, smoke hatches, roof vents, electrical
and lighting systems, and fire sprinklers, and the emergency generator(s)
described in Paragraph 38.H. of this Lease, with materials and workmanship of
the same character, kind and quality as the original. Tenant shall at Tenant's
expense also perform regular removal of trash and debris. Notwithstanding
anything to the contrary contained herein, Tenant shall, at its expense,
promptly repair any damage to the Premises or the Building or Project resulting
from or caused by any negligence or act of Tenant or Tenant's Parties. Nothing
herein shall expressly or by implication render Tenant Landlord's agent or
contractor to effect any repairs or maintenance required of Tenant under this
Paragraph 11, as to all of which Tenant shall be solely responsible.

                                 12. ALTERATIONS

A. Except for interior, nonstructural alterations costing less than Twenty-five
Thousand Dollars ($25,000.00) to perform, Tenant shall not make, or allow to be
made, any alterations, physical additions, improvements or partitions, in,
about or to the Premises ("ALTERATIONS") without obtaining the prior written
consent of Landlord, which consent shall not be unreasonably withheld, delayed
or conditioned with respect to proposed Alterations which: (a) comply with all
applicable Regulations; (b) are, in Landlord's opinion, compatible with the
Building or the Project and its mechanical, plumbing, electrical,
heating/ventilation/air conditioning systems, and will not cause the Building or
Project or such systems to be required to be modified to comply with any
Regulations (including, without limitation, the Americans With Disabilities Act)
unless Tenant agrees to perform the same at its sole cost and expense; and (c)
will not interfere with the use and occupancy of any other portion of the
Project by any other tenant or its invitees. Specifically, but without limiting
the generality of the foregoing, Landlord shall have the right of written
consent (which consent shall not be unreasonably withheld, delayed or
conditioned) for all plans and specifications for the proposed Alterations,
construction means and methods, all appropriate permits and licenses, any
contractor or subcontractor to be employed on the work of Alterations, and the
time for performance of such work, and may impose reasonable rules and
regulations for contractors and subcontractors performing such work. Tenant
shall also supply to Landlord any documents and information reasonably requested
by Landlord in connection with Landlord's consideration of a request for
approval hereunder. Tenant shall cause all Alterations to be accomplished in a
first-class, good and workmanlike manner, and to comply with all applicable
Regulations and Paragraph 27 hereof. If Landlord does not respond in writing
within ten (10) days of receipt of Tenant's plan, stating with specificity its
reasons therefor, Tenant shall deliver a second notice to Landlord, stating in
bold type on the first page thereof "URGENT - DELAY NOTICE," which notice may be
delivered by facsimile to Landlord at Landlord's Notice Address and as otherwise
set forth in Paragraph 32, and if Landlord fails to respond within five (5) days
thereafter, Landlord's consent shall be deemed given. Tenant shall at Tenant's
sole expense, perform any additional work required under applicable Regulations
due to the Alterations hereunder. No review or consent by Landlord of or to any
proposed Alteration or additional work shall constitute a waiver of Tenant's
obligations under this Paragraph 12. Tenant shall reimburse Landlord for all
third-party costs which Landlord may reasonably and actually incur in connection
with granting approval to Tenant for any such Alterations, including any costs
or expenses which Landlord may incur in electing to have outside architects and
engineers review said plans and specifications, to the extent it is reasonably
necessary to do so. All such Alterations shall remain the property of Tenant
until the expiration or earlier termination of this Lease, at which time they
shall be and become the property of Landlord; provided, however, that Landlord
may, at Landlord's option, require that Tenant, at Tenant's expense, remove any
or all Alterations made by Tenant which Landlord indicated at the time consent
thereto was granted would have to be removed and restore the Premises by the
expiration or earlier termination of this Lease, to their condition existing
prior to the construction of any such Alterations. All such removals and
restoration shall be accomplished in a first-class and good and workmanlike
manner so as not to cause any damage to the Premises or Project whatsoever. If
Tenant fails to remove such Alterations or Tenant's trade fixtures or furniture
or other personal property, Landlord may keep and use them or remove any of them
and cause them to be stored or sold in accordance with applicable law, at
Tenant's sole expense. In addition to and wholly apart from Tenant's obligation
to pay Tenant's Proportionate Share of Operating Expenses, Tenant shall be
responsible for and shall pay prior to delinquency any taxes or governmental
service fees, possessory interest taxes, fees or charges in lieu of any such
taxes, capital levies, or other charges imposed upon, levied with respect to or
assessed against its fixtures or personal property, on the value of Alterations
within the Premises, and on Tenant's interest pursuant to this Lease, or any
increase in any of the foregoing based on such Alterations. To the extent that
any such taxes are not separately assessed or billed to Tenant, Tenant shall pay
the amount thereof as invoiced to Tenant by Landlord.

        The work necessary to make such Alterations shall be performed by
employees, contractors or space planners employed by Landlord or, with
Landlord's prior written consent, which consent shall not be unreasonably
withheld, delayed or conditioned, by space planners and/or contractors licensed
in California which are employed by Tenant. In addition, if Landlord elected at
the time consent to any such Alterations was granted to require that any such
Alterations be removed by Tenant upon the expiration or earlier termination of
the Term, and Landlord elects to be responsible for performing such removal,
then notwithstanding the provisions of the preceding paragraph, Tenant shall pay
to Landlord the cost of removing any such Alterations and restoring the Premises
to their original condition such cost to include a reasonable charge for
Landlord's overhead and profit as provided above, and such amount may be
deducted from the Security Deposit or any other sums or amounts held by Landlord
under this Lease.

B. In compliance with Paragraph 27 hereof, at least ten (10) business days
before beginning construction of any Alteration, Tenant shall give Landlord
written notice of the expected commencement date of that construction to permit
Landlord to post and record a notice of non-responsibility. Upon substantial
completion of construction, if the law so provides, Tenant shall cause a timely
notice of completion to be recorded in the office of the recorder of the county
in which the Building is located.

                                    13. SIGNS

Tenant shall not place, install, affix, paint or maintain any signs, notices,
graphics or banners whatsoever or any window decor which is visible in or from
public view or corridors, the common areas or the exterior of the Premises or
the Building, in or on any exterior window

                                       11
<PAGE>   76

or window fronting upon any common areas or service area or upon any truck doors
or man doors without Landlord's prior written approval which Landlord shall have
the right to withhold in its absolute and sole discretion; provided that
Tenant's name shall be included in any Building-standard door and directory
signage, if any, and Tenant shall have the right to install at Tenant's sole
cost, expense and responsibility, identifying signage on the existing monument
sign at the entranceway to the Project, in accordance with Landlord's Building
signage criteria attached as EXHIBIT F hereto, including without limitation,
payment by Tenant of any fee charged by Landlord for maintaining such signage,
which fee shall constitute Additional Rent hereunder. Any installation of signs,
notices, graphics or banners on or about the Premises or Project approved by
Landlord shall be subject to any Regulations and to any other requirements
imposed by Landlord. Tenant shall remove all such signs or graphics by the
expiration or any earlier termination of this Lease. Such installations and
removals shall be made in such manner as to avoid injury to or defacement of the
Premises, Building or Project and any other improvements contained therein, and
Tenant shall repair any injury or defacement including without limitation
discoloration caused by such installation or removal.

                         14. INSPECTION/POSTING NOTICES

After reasonable notice and subject to such security requirements as Tenant may
reasonably impose, except in emergencies where no such notice or compliance with
any such security requirements shall be required, Landlord and Landlord's agents
and representatives, shall have the right to enter the Premises to inspect the
same, to clean, to perform such work as may be permitted or required hereunder,
to make repairs, improvements or alterations to the Premises, Building or
Project or to other tenant spaces therein, to deal with emergencies, to post
such notices as may be permitted or required by law to prevent the perfection of
liens against Landlord's interest in the Project or to exhibit the Premises to
prospective tenants (during the last twelve (12) months of the Term or extended
Term), purchasers, encumbrancers or to others, or for any other purpose as
Landlord may deem necessary or desirable; provided, however, that Landlord shall
use reasonable efforts not to unreasonably interfere with Tenant's business
operations. Tenant shall have the right to require a representative of Tenant to
accompany Landlord during any such entry or inspection. Tenant shall not be
entitled to any abatement of Rent by reason of the exercise of any such right of
entry. Tenant waives any claim for damages for any injury or inconvenience to or
interference with Tenant's business, any loss of occupancy or quiet enjoyment of
the Premises, and any other loss occasioned thereby except for any damage to
persons as properly caused by the active negligence or willful misconduct of
Landlord or its employees, agents or contractors. Landlord shall at all times
have and retain a key with which to unlock all of the doors in, upon and about
the Premises, excluding Tenant's vaults and safes or special security areas
(designated in advance), and Landlord shall have the right to use any and all
means which Landlord may deem necessary or proper to open said doors in an
emergency, in order to obtain entry to any portion of the Premises, and any
entry to the Premises or portions thereof obtained by Landlord by any of said
means, or otherwise, shall not be construed 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 portions thereof. At any time within six (6)
months prior to the expiration of the Term or following any earlier termination
of this Lease or agreement to terminate this Lease, Landlord shall have the
right to erect on the Premises, Building and/or Project a suitable sign
indicating that the Premises are available for lease.

                           15. SERVICES AND UTILITIES

A. Tenant shall pay directly for all water, gas, heat, air conditioning, light,
power, telephone, sewer, sprinkler charges and other utilities and services used
on or from the Premises, together with any taxes, penalties, surcharges or the
like pertaining thereto, and maintenance charges for utilities and shall furnish
all electric light bulbs, ballasts and tubes. Notwithstanding anything in this
Lease to the contrary, Tenant shall have the right to conduct its business
operations within the Premises, and to receive reasonable quantities of water,
electricity and HVAC in connection therewith, seven (7) days per week,
twenty-four (24) hours per day. If any such services are not separately billed
or metered to Tenant, Tenant shall pay a proportion, as determined by Landlord,
of all charges jointly serving other premises. All sums payable under this
Paragraph 15 shall constitute Additional Rent hereunder. Landlord shall use
reasonable efforts to reasonably capture any material benefit available through
deregulation of electricity supply or of the supply of other utilities.

B. Tenant acknowledges that Tenant has inspected and accepts the water,
electricity, heat and air conditioning and other utilities and services being
supplied or furnished to the Premises as of the date Tenant takes possession of
the Premises, if any, as being sufficient in their present condition, "as is,"
for the Permitted Use, and for Tenant's intended operations in the Premises.

C. Tenant shall not without written consent of Landlord (which consent shall not
be unreasonably withheld, delayed or conditioned) use any apparatus, equipment
or device in the Premises, including without limitation, computers, electronic
data processing machines, copying machines, and other machines, using excess
lighting or using electric current, water, or any other resource in excess of or
which will in any way increase the amount of electricity, water, or any other
resource being furnished or supplied for the use of the Premises for reasonable
and normal office use, in each case as of the date Tenant takes possession of
the Premises as reasonably determined by Landlord, or which will require
additions or alterations to or interfere with the Building power distribution
systems; nor connect with electric current, except through existing electrical
outlets in the Premises or water pipes, any apparatus, equipment or device for
the purpose of using electrical current, water, or any other resource. If Tenant
shall require water or electric current or any other resource in excess of that
being furnished or supplied for the use of the Premises as of the date Tenant
takes possession of the Premises, if any, as reasonably determined by Landlord,
Tenant shall first procure the written consent of Landlord (which consent shall
not be unreasonably withheld, delayed or conditioned), to the use thereof, and
Landlord may cause a special meter to be installed in the Premises so as to
measure the amount of water, electric current or other resource consumed for any
such other use. Tenant shall pay directly to Landlord as an addition to and
separate from payment of Operating Expenses the cost of all such additional
resources, energy, utility service and meters (and of installation, maintenance
and repair thereof and of any additional circuits or other equipment necessary
to furnish such additional resources, energy, utility or service). Landlord may
add to the separate or metered charge a recovery of additional expense incurred
in keeping account of the excess water, electric current or other resource so
consumed. Landlord shall not be liable for any damages directly or indirectly
resulting from nor shall the Rent or any monies owed Landlord under this Lease
herein reserved be abated by reason of: (a) the installation, use or
interruption of use of any equipment used in connection with the furnishing of
any such utilities or services, or any change in the character or means of
supplying or providing any such utilities or services or any supplier thereof;
(b) the failure to furnish or delay in furnishing any such utilities or services
when such failure or delay is caused by acts of God or the elements, labor
disturbances of any character, or any other accidents or other conditions beyond
the reasonable control of Landlord or because of any interruption of service due
to Tenant's use of water, electric current or other resource in excess of that
being supplied or furnished for the use of the Premises as of the date Tenant
takes possession of the Premises; or (c) the inadequacy, limitation,
curtailment, rationing or restriction on use of water, electricity, gas or any
other form of energy or any other service or utility whatsoever serving the
Premises or Project otherwise; or (d) the partial or total unavailability of any
such utilities or services to the Premises or the Building, whether by
Regulation or otherwise; nor shall any such occurrence constitute an actual or
constructive eviction of Tenant. Landlord shall further have no

                                       12
<PAGE>   77

obligation to protect or preserve any apparatus, equipment or device installed
by Tenant in the Premises. In addition, Landlord reserves the right to change
the supplier or provider of any such utility or service from time to time.
Landlord may, but shall not be obligated to, upon notice to Tenant, contract
with or otherwise obtain any electrical or other such service for or with
respect to the Premises or Tenant's operations therein from any supplier or
provider of any such service. Tenant shall cooperate with Landlord and any
supplier or provider of such services designated by Landlord from time to time
to facilitate the delivery of such services to Tenant at the Premises and to the
Building and Project, including without limitation allowing Landlord and
Landlord's suppliers or providers, and their respective agents and contractors,
reasonable access to the Premises for the purpose of installing, maintaining,
repairing, replacing or upgrading such service or any equipment or machinery
associated therewith.

    Subject to Paragraph 35 of this Lease, for services or utilities that
    Landlord is required to supply to the Premises hereunder, but is actively
    negligent in adequately providing or altogether fails to provide, Tenant's
    Rent shall be abated or reduced for such period of time that the Premises or
    portion thereof is not supplied with such services or utilities, in
    proportion to the rentable square feet of the Premises that is so affected
    bears to the total rentable square feet of the Premises.

D. SUBJECT TO THE PROVISIONS CONTAINED IN THE LAST SENTENCE OF PARAGRAPH 38.H.,
Landlord acknowledges and agrees to Tenant's exclusive use, operation,
maintenance, repair and security protection of those certain underground
conduit, vault and equipment facilities within the Project for Tenant's
telecommunication cabling and equipment. Furthermore, Tenant agrees to and
accepts complete and full responsibility and control of the facilities described
in the preceding sentence.

                                16. SUBORDINATION

Without the necessity of any additional document being executed by Tenant for
the purpose of effecting a subordination, the Lease shall be and is hereby
declared to be subject and subordinate at all times to: (a) all ground leases or
underlying leases which may hereafter be executed affecting the Premises and/or
the land upon which the Premises and Project are situated, or both; and (b) any
mortgage or deed of trust which may be placed upon the Building, the Project
and/or the land upon which the Premises or the Project are situated, or said
ground leases or underlying leases, or Landlord's interest or estate in any of
said items which is specified as security. Notwithstanding the foregoing,
Landlord shall have the right to subordinate or cause to be subordinated any
such ground leases or underlying leases or any such liens to this Lease. If any
ground lease or underlying lease terminates for any reason or any mortgage or
deed of trust is foreclosed or a conveyance in lieu of foreclosure is made for
any reason, Tenant shall, notwithstanding any subordination, attorn to and
become the Tenant of the successor in interest to Landlord provided that Tenant
shall not be disturbed in its possession under this Lease by such successor in
interest so long as Tenant is not in default under this Lease beyond the
expiration of all applicable grace, notice and cure periods. Within ten (10)
days after request by Landlord, Tenant shall execute and deliver any
commercially reasonable additional documents evidencing Tenant's attornment or
the subordination of this Lease with respect to any such ground leases or
underlying leases or any such mortgage or deed of trust, in the form reasonably
requested by Landlord or by any ground landlord, mortgagee, or beneficiary under
a deed of trust, subject to such nondisturbance requirement.

                            17. FINANCIAL STATEMENTS

At the request of Landlord from time to time, Tenant shall provide to Landlord
Tenant's and any guarantor's current financial statements or other information
discussing financial worth of Tenant and any guarantor, which Landlord shall use
solely for purposes of this Lease and in connection with the ownership,
management, financing and disposition of the Project.

                            18. ESTOPPEL CERTIFICATE

Tenant agrees from time to time, but not more than twice in any calendar year,
within ten (10) business days after request of Landlord, to deliver to Landlord,
or Landlord's designee, an estoppel certificate stating that this Lease is in
full force and effect, that this Lease has not been modified (or stating all
modifications, written or oral, to this Lease), the date to which Rent has been
paid, the unexpired portion of this Lease, that there are no current defaults by
Landlord or Tenant under this Lease (or specifying any such defaults), that the
leasehold estate granted by this Lease is the sole interest of Tenant in the
Premises and/or the land at which the Premises are situated (subject to such
rights of first refusal and/or options to purchase as may be set forth herein),
and such other matters pertaining to this Lease as may be reasonably requested
by Landlord or any mortgagee, beneficiary, purchaser or prospective purchaser of
the Building or Project or any interest therein. If Tenant fails to execute such
certificate within such ten (10) business day period, and such failure continues
for more than five (5) days following delivery of a second request therefor,
which second notice shall be labeled at the top in bold letters "URGENT - DELAY
NOTICE," then the failure by Tenant to execute and deliver such certificate A
DEFAULT UNDER THIS LEASE. Tenant agrees that if Tenant fails to execute and
deliver such certificate within second five (5) day period, Landlord may execute
and deliver such certificate on Tenant's behalf and that such certificate shall
be binding on Tenant. Landlord and Tenant intend that any statement delivered
pursuant to this Paragraph may be relied upon by any mortgagee, beneficiary,
purchaser or prospective purchaser of the Building or Project or any interest
therein.

                              19. SECURITY DEPOSIT

In the event Tenant does not exercise its first and/or second option to extend
the Term pursuant to Paragraph 38.B. of this Lease, Tenant agrees to deposit
with Landlord no later than twelve (12) months prior to the expiration of the
Term, or the extended Term, a security deposit as stated in the Basic Lease
Information (the "SECURITY DEPOSIT"), which sum shall be held and owned by
Landlord, without obligation to pay interest, as security for the performance of
Tenant's covenants and obligations under this Lease. The Security Deposit is not
an advance rental deposit or a measure of damages incurred by Landlord in case
of Tenant's default. Upon the occurrence of any event of default by Tenant,
Landlord may from time to time, without prejudice to any other remedy provided
herein or by law, use such fund as a credit to the extent necessary to credit
against any arrears of Rent or other payments due to Landlord hereunder, and any
other damage, injury, expense or liability caused by such event of default, and
Tenant shall pay to Landlord, on demand, the amount so applied in order to
restore the Security Deposit to its original amount. Although the Security
Deposit shall be deemed the property of Landlord, any remaining balance of such
deposit shall be returned by Landlord to Tenant at such time after termination
of this Lease that all of Tenant's obligations under this Lease have been
fulfilled, reduced by such amounts as may be required by Landlord to remedy
defaults on the part of Tenant in the payment of Rent or other obligations of
Tenant under this Lease, to repair damage to the

                                       13
<PAGE>   78

Premises, Building or Project caused by Tenant or any Tenant's Parties and to
clean the Premises. Landlord may use and commingle the Security Deposit with
other funds of Landlord.

                       20. LIMITATION OF TENANT'S REMEDIES

The obligations and liability of Landlord to Tenant for any default by Landlord
under the terms of this Lease are not personal obligations of Landlord or of the
individual or other partners of Landlord or its or their partners, directors,
officers, or shareholders, and Tenant agrees to look solely to Landlord's
interest in the Project (including the rents, issues and proceeds therefrom) for
the recovery of any amount from Landlord, and shall not look to other assets of
Landlord nor seek recourse against the assets of the individual or other
partners of Landlord or its or their partners, directors, officers or
shareholders. Any lien obtained to enforce any such judgment and any levy of
execution thereon shall be subject and subordinate to any lien, mortgage or deed
of trust on the Project. Under no circumstances shall Tenant have the right to
offset against or recoup Rent or other payments due and to become due to
Landlord hereunder except as expressly provided in Paragraph 23.B. below or
elsewhere in this Lease, which Rent and other payments shall be absolutely due
and payable hereunder in accordance with the terms hereof.

                          21. ASSIGNMENT AND SUBLETTING

A.      (1) GENERAL. Tenant shall not assign or pledge this Lease or sublet the
        Premises or any part thereof, whether voluntarily or by operation of
        law, or permit the use or occupancy of the Premises or any part thereof
        by anyone other than Tenant, or suffer or permit any such assignment,
        pledge, subleasing or occupancy, without Landlord's prior written
        consent except as provided herein which consent shall not be
        unreasonably withheld, delayed or conditioned. If Tenant desires to
        assign this Lease or sublet any or all of the Premises, Tenant shall
        give Landlord written notice (the "TRANSFER NOTICE") at least thirty
        (30) days prior to the anticipated effective date of the proposed
        assignment or sublease, which shall contain all of the information
        reasonably requested by Landlord to address Landlord's decision criteria
        specified hereinafter. Landlord shall then have a period of fifteen (15)
        business days following receipt of the Transfer Notice to notify Tenant
        in writing whether Landlord consents to the proposed assignment or
        sublease, subject, however, to Landlord's prior written consent of the
        proposed assignee or subtenant and of any related documents or
        agreements associated with the assignment or sublease and if Landlord
        withholds such consent, stating with specificity the reasons therefor.
        Consent to any assignment or subletting shall not constitute consent to
        any subsequent transaction to which this Paragraph 21 applies.

        (2) CONDITIONS OF LANDLORD'S CONSENT. Without limiting the other
        instances in which it may be reasonable for Landlord to withhold
        Landlord's consent to an assignment or subletting, Landlord and Tenant
        acknowledge that it shall be reasonable for Landlord to withhold
        Landlord's consent in the following instances: if the proposed assignee
        does not agree to be bound by and assume the obligations of Tenant under
        this Lease in form and substance reasonably satisfactory to Landlord;
        the use of the Premises by such proposed assignee or subtenant would not
        be a Permitted Use or would violate any exclusivity or other arrangement
        which Landlord has with any other tenant or occupant or any Regulation
        or would increase the Occupancy Density or Parking Density of the
        Building or Project, as reasonably determined by Landlord; the proposed
        assignee or subtenant is not of sound financial condition as determined
        by Landlord in Landlord's reasonable discretion; the proposed assignee
        or subtenant is a governmental agency that occupies more than
        twenty-five percent (25%) of the Premises; the proposed assignee or
        subtenant does not have a good reputation as a tenant of property or a
        good business reputation; the proposed assignee or subtenant is a person
        with whom Landlord is negotiating to lease space in the Project or is a
        present tenant of the Project; the assignment or subletting would entail
        any Alterations which would lessen the value of the leasehold
        improvements in the Premises or use of any Hazardous Materials or other
        noxious use or use which may disturb other tenants of the Project; or
        Tenant is in default of any obligation of Tenant under this Lease, or
        Tenant has defaulted under this Lease on three (3) or more occasions
        during any twelve (12) months preceding the date that Tenant shall
        request consent. Failure by or refusal of Landlord to consent to a
        proposed assignee or subtenant shall not cause a termination of this
        Lease. At the option of Landlord, a surrender and termination of this
        Lease shall operate as an assignment to Landlord of some or all
        subleases or subtenancies. Landlord shall exercise this option by giving
        notice of that assignment to such subtenants on or before the effective
        date of the surrender and termination. In connection with each request
        for assignment or subletting, Tenant shall pay to Landlord Landlord's
        standard fee for approving such requests, as well as all costs incurred
        by Landlord or any mortgagee or ground lessor in approving each such
        request and effecting any such transfer, including, without limitation,
        reasonable attorneys' fees in an amount not to exceed Twenty-five
        Hundred Dollars ($2,500.00).

B. BONUS RENT. For any subleasing or assignment that is in the aggregate less
than twenty-five percent (25%) of the Premises, any Rent or other consideration
realized by Tenant under any such sublease or assignment, in excess of the Rent
payable hereunder, after amortization of all transaction costs reasonably
incurred in connection therewith, including but not limited to reasonable
brokerage commission incurred by Tenant, legal fees, costs of improvements,
shall be divided and paid, fifty percent (50%) to Tenant, fifty percent (50%) to
Landlord ("BONUS RENT"). However, for any subleasing or assignment that is in
the aggregate twenty-five percent (25%) or more of the Premises, then the Bonus
Rent shall be divided and paid twenty-five percent (25%) to Tenant and
seventy-five (75%) to Landlord. In any subletting or assignment undertaken by
Tenant, Tenant shall diligently seek to obtain the maximum rental amount
available in the marketplace for comparable space available for primary leasing.

C. CORPORATION. If Tenant is a corporation, a transfer of corporate shares by
sale, assignment, bequest, inheritance, operation of law or other disposition
(including such a transfer to or by a receiver or trustee in federal or state
bankruptcy, insolvency or other proceedings) resulting in a change in the
present control of such corporation or any of its parent corporations by the
person or persons owning a majority of said corporate shares, shall constitute
an assignment for purposes of this Lease. So long as Franklin Resources, Inc.,
is the "Tenant" in possession of the Premises, and Tenant is not in default of
this Lease after the expiration of all applicable grace, notice and cure
periods, Tenant shall have the right subject to the terms and conditions
hereinafter set forth, without the consent of Landlord, to (a) assign its
interest in this Lease (i) to any corporation which is a successor to Tenant
either by merger or consolidation, or (ii) to a purchaser of all or
substantially all of Tenant's assets (provided such purchaser shall have also
assumed substantially all of Tenant's liabilities), or to a corporation or other
entity which shall control, be under the control of, or be under common control
with, Franklin Resources, Inc., (the term "control" as used herein shall be
deemed to mean ownership of more than fifty percent (50%) of the outstanding
voting stock of a corporation, or other majority equity and controlling interest
if Tenant is not a corporation) (any such entity being a "Related Entity"), or
(b) sublease all or any portion of the Premises to a Related Entity; upon the
condition that (i) the principal purpose of such assignment or sublease is not
the acquisition of Tenant's interest in this Lease (except if such assignment or
sublease is made to a Related Entity and is made for a valid intra-corporate
business purpose and is not made to circumvent the provisions of this Paragraph
21), and (ii) any such

                                       14
<PAGE>   79

assignee shall have a net worth and annual income and cash flow, determined in
accordance with generally accepted accounting principles, consistently applied,
after giving effect to such assignment, in amounts necessary to perform its
duties, obligations and liabilities hereunder, as reasonably determined by
Landlord. Tenant shall, within ten (10) business days after execution thereof,
deliver to Landlord (a) a duplicate original instrument of assignment, in form
and substance reasonably satisfactory to Landlord, duly executed by Tenant, (b)
an instrument in form and substance reasonably satisfactory to Landlord, duly
executed by the assignee, in which such assignee shall assume observance and
performance of, and agree to be personally bound by all of the terms, covenants
and conditions of this Lease on Tenant's part to be observed and performed, or
(c) a duplicate original sublease in form and substance reasonably satisfactory
to Landlord, duly executed by Tenant and subtenant, in which such assignee shall
assume observance and performance of, and agree to be personally bound by all of
the terms, covenants and conditions of this Lease on Tenant's part to be
observed and performed.

D. UNINCORPORATED ENTITY. If Tenant is a partnership, joint venture,
unincorporated limited liability company or other unincorporated business form,
a transfer of the interest of persons, firms or entities responsible for
managerial control of Tenant by sale, assignment, bequest, inheritance,
operation of law or other disposition, so as to result in a change in the
present control of said entity and/or of the underlying beneficial interests of
said entity and/or a change in the identity of the persons responsible for the
general credit obligations of said entity shall constitute an assignment for all
purposes of this Lease.

E. LIABILITY. No assignment or subletting by Tenant, permitted or otherwise,
shall relieve Tenant of any obligation under this Lease or alter the primary
liability of the Tenant named herein for the payment of Rent or for the
performance of any other obligations to be performed by Tenant, including
obligations contained in Paragraph 25 with respect to any assignee or subtenant.
Landlord may collect rent or other amounts or any portion thereof from any
assignee, subtenant, or other occupant of the Premises, permitted or otherwise,
and apply the net rent collected to the Rent payable hereunder, but no such
collection shall be deemed to be a waiver of this Paragraph 21, or the
acceptance of the assignee, subtenant or occupant as tenant, or a release of
Tenant from the further performance by Tenant of the obligations of Tenant under
this Lease. Any assignment or subletting which conflicts with the provisions
hereof shall be void.

                                  22. AUTHORITY

Landlord represents and warrants that it has full right and authority to enter
into this Lease and to perform all of Landlord's obligations hereunder and that
all persons signing this Lease on its behalf are authorized to do. Tenant and
the person or persons, if any, signing on behalf of Tenant, jointly and
severally represent and warrant that Tenant has full right and authority to
enter into this Lease, and to perform all of Tenant's obligations hereunder, and
that all persons signing this Lease on its behalf are authorized to do so.

                                23. CONDEMNATION

A. CONDEMNATION RESULTING IN TERMINATION. If the whole or any substantial part
of the Premises should be taken or condemned for any public use under any
Regulation, or by right of eminent domain, or by private purchase in lieu
thereof, and the taking would prevent or materially interfere with the Permitted
Use of the Premises, either party shall have the right to terminate this Lease
at its option. If any material portion of the Building or Project is taken or
condemned for any public use under any Regulation, or by right of eminent
domain, or by private purchase in lieu thereof, Landlord may terminate this
Lease at its option. In either of such events, the Rent shall be abated during
the unexpired portion of this Lease, effective when the physical taking of said
Premises shall have occurred.

B. CONDEMNATION NOT RESULTING IN TERMINATION. If a portion of the Project of
which the Premises are a part should be taken or condemned for any public use
under any Regulation, or by right of eminent domain, or by private purchase in
lieu thereof, and the taking prevents or materially interferes with the
Permitted Use of the Premises, and this Lease is not terminated as provided in
Paragraph 23.A. above, the Rent payable hereunder during the unexpired portion
of the Lease shall be reduced, beginning on the date when the physical taking
shall have occurred, to such amount as may be fair and reasonable under all of
the circumstances, but only after giving Landlord credit for all sums received
or to be received by Tenant by the condemning authority. Notwithstanding
anything to the contrary contained in this Paragraph, if the temporary use or
occupancy of any part of the Premises shall be taken or appropriated under power
of eminent domain during the Term, this Lease shall be and remain unaffected by
such taking or appropriation and Tenant shall continue to pay in full all Rent
payable hereunder by Tenant during the Term; in the event of any such temporary
appropriation or taking, Tenant shall be entitled to receive that portion of any
award which represents compensation for the use of or occupancy of the Premises
during the Term, and Landlord shall be entitled to receive that portion of any
award which represents the cost of restoration of the Premises and the use and
occupancy of the Premises.

C. AWARD. Landlord shall be entitled to (and Tenant shall assign to Landlord)
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 any sums paid by
virtue of such proceedings, whether or not attributable to the value of any
unexpired portion of this Lease, except as expressly provided in this Lease.
Notwithstanding the foregoing, any compensation specifically and separately
awarded Tenant for Tenant's personal property and moving costs, shall be and
remain the property of Tenant and the unamortized value of improvements to the
Premises paid for by Tenant.

D. WAIVER OF CCP Section 1265.130. Each party waives the provisions of
California Civil Code Procedure Section 1265.130 allowing either party to
petition the superior court to terminate this Lease as a result of a partial
taking.

                               24. CASUALTY DAMAGE

A. GENERAL. If the Premises or Building should be damaged or destroyed by fire,
tornado, or other casualty (collectively, "CASUALTY"), Tenant shall give
immediate written notice thereof to Landlord. Within thirty (30) days after
Landlord's receipt of such notice, Landlord shall notify Tenant whether in
Landlord's estimation (based upon the certificate of a general contractor
reasonably acceptable to Tenant) material restoration of the Premises can
reasonably be made within one hundred eighty (180) days from the date of such
notice and receipt of required permits for such restoration. Landlord's
determination shall be binding on Tenant.

B. WITHIN 180 DAYS. If the Premises or Building should be damaged by Casualty to
such extent that material restoration can in Landlord's estimation be reasonably
completed within one hundred eighty (180) days after the date of such notice and
receipt of required permits for such restoration, this Lease shall not
terminate. Provided that insurance proceeds are received by Landlord to fully
repair the damage (less the amount of any deductible), Landlord shall proceed to
rebuild and repair the Premises in the manner reasonably determined by Landlord,
except that Landlord shall not be required to rebuild, repair or replace any
part of the Alterations which may have been placed on or about the Premises by
Tenant. If the Premises are untenantable in whole or in part following such
damage, the Rent payable hereunder during the period in which they are
untenantable shall be abated proportionately.

C. GREATER THAN 180 DAYS. If the Premises or Building should be damaged by
Casualty to such extent that rebuilding or repairs cannot in Landlord's
estimation be reasonably completed within one hundred eighty (180) days after
the date of such notice and receipt of required permits for such rebuilding or
repair, then either party shall have the option to be exercised within thirty
(30) days following receipt of Landlord's estimate of terminating this Lease
effective upon the date of the occurrence of such damage, in which event the
Rent shall be abated during the unexpired portion of this Lease.

                                       15
<PAGE>   80

If neither party elects to so terminate, Landlord shall commence to rebuild or
repair the Premises diligently and in the manner reasonably determined by
Landlord. Notwithstanding the above, Landlord shall not be required to rebuild,
repair or replace any part of any Alterations which may have been placed, on or
about the Premises by Tenant. If the Premises are untenantable in whole or in
part following such damage, the Rent payable hereunder during the period in
which they are untenantable shall be abated proportionately.

D. TENANT'S FAULT. Notwithstanding anything herein to the contrary, if the
Premises or any other portion of the Building are damaged by Casualty resulting
from the fault, negligence, or breach of this Lease by Tenant or any of Tenant's
Parties, Base Rent and Additional Rent shall not be diminished during the repair
of such damage (to the extent Tenant is responsible for the loss and Landlord is
not being covered by any other insurance proceeds) and Tenant shall be liable to
Landlord for the cost and expense of the repair and restoration of the Building
caused thereby to the extent such cost and expense is not covered by insurance
proceeds.

E. INSURANCE PROCEEDS. Notwithstanding anything herein to the contrary, if the
Premises or Building are damaged or destroyed and are not fully covered by the
insurance proceeds received by Landlord or if the holder of any indebtedness
secured by a mortgage or deed of trust covering the Premises requires, despite
Landlord's commercially reasonable efforts to obtain such proceeds, that the
insurance proceeds be applied to such indebtedness, then in either case Landlord
shall have the right to terminate this Lease by delivering written notice of
termination to Tenant within thirty (30) days after the date of notice to
Landlord that said damage or destruction is not fully covered by insurance or
such requirement is made by any such holder, as the case may be, whereupon this
Lease shall terminate.

F. WAIVER. This Paragraph 24 shall be Tenant's sole and exclusive remedy in the
event of damage or destruction to the Premises or the Building. As a material
inducement to Landlord entering into this Lease, Tenant hereby waives any rights
it may have under Sections 1932, 1933(4), 1941 or 1942 of the Civil Code of
California with respect to any destruction of the Premises, Landlord's
obligation for tenantability of the Premises and Tenant's right to make repairs
and deduct the expenses of such repairs, or under any similar law, statute or
ordinance now or hereafter in effect.

G. TENANT'S PERSONAL PROPERTY. In the event of any damage or destruction of the
Premises or the Building, under no circumstances shall Landlord be required to
repair any injury or damage to, or make any repairs to or replacements of,
Tenant's personal property.

                                25. HOLDING OVER

Unless Landlord expressly consents in writing to Tenant's holding over, Tenant
shall be unlawfully and illegally in possession of the Premises, whether or not
Landlord accepts any rent from Tenant or any other person while Tenant remains
in possession of the Premises without Landlord's written consent. If Tenant
shall retain possession of the Premises or any portion thereof without
Landlord's consent following the expiration of this Lease or sooner termination
for any reason, then Tenant shall pay to Landlord for each day of such retention
two hundred percent (200%) the amount of daily rental as of the last month prior
to the date of expiration or earlier termination. Tenant shall also indemnify,
defend, protect and hold Landlord harmless from any loss, liability or cost,
including consequential and incidental damages and reasonable attorneys' fees,
incurred by Landlord resulting from delay by Tenant in surrendering the Premises
within thirty (30) days following the expiration or earlier termination of the
Term or extended Term of this Lease, including, without limitation, any claims
made by the succeeding tenant founded on such delay. Acceptance of Rent by
Landlord following expiration or earlier termination of this Lease, or following
demand by Landlord for possession of the Premises, shall not constitute a
renewal of this Lease, and nothing contained in this Paragraph 25 shall waive
Landlord's right of reentry or any other right. Additionally, if upon expiration
or earlier termination of this Lease, or following demand by Landlord for
possession of the Premises, Tenant has not fulfilled its obligation with respect
to repairs and cleanup of the Premises or any other Tenant obligations as set
forth in this Lease, then Landlord shall have the right to perform any such
obligations as it deems necessary at Tenant's sole cost and expense, and any
time required by Landlord to complete such obligations shall be considered a
period of holding over and the terms of this Paragraph 25 shall apply. The
provisions of this Paragraph 25 shall survive any expiration or earlier
termination of this Lease. If by written notice to Landlord delivered not later
than twelve (12) months prior to the Term Expiration Date, or the expiration of
the extended Term (the "Hold-Over Notice"), Tenant advises Landlord of its
intent to hold-over specifying the period of such hold-over (which period must
be for a period of no longer than six (6) months) (the "Hold-Over Term") then
Tenant may, as a matter of right, remain in possession following the Term
Expiration Date or the expiration of the extended Term, as the case may be, for
the Hold-Over Term set forth in the Hold-Over Notice; provided, that the Base
Rent for the Hold-Over Term shall be one hundred fifty percent (150%) of the sum
of the Base Rent and other charges payable for the last month of the Term or
extended Term. In no event under the preceding sentence, shall Tenant have the
right to hold-over in the Premises for more than one (1) six (6) month or
shorter period beyond the Term Expiration Date or the expiration of the extended
Term. NOTWITHSTANDING THE FOREGOING, IN THE EVENT OF ANY SUCH HOLDING OVER,
TENANT SHALL NOT HAVE ANY RIGHT TO EXERCISE (A) THE PHASE C PREMISES EXPANSION
OPTION AS SET FORTH IN EXHIBIT H; (B) THE FIRST RIGHT TO PURCHASE THE PROJECT AS
SET FORTH IN EXHIBIT I, OR (C) THE OPTION TO PURCHASE THE PROJECT AS SET FORTH
IN EXHIBIT J.

                                   26. DEFAULT

A. EVENTS OF DEFAULT. The occurrence of any of the following shall constitute an
event of default on the part of Tenant:

        (1)    ABANDONMENT.

        (2) NONPAYMENT OF RENT. Failure to pay any installment of Rent or any
        other amount due and payable hereunder upon the date when said payment
        is due, as to which time is of the essence.

        (3) OTHER OBLIGATIONS. Failure to perform any obligation, agreement or
        covenant under this Lease other than those matters specified in
        subparagraphs (1) and (2) of this Paragraph 26.A., such failure
        continuing for twenty (20) days after written notice of such failure
        unless such default cannot reasonably be cured within such twenty (20)
        day period and Tenant shall within such period commence with due
        diligence and dispatch the curing of such default, and having so
        commenced, shall thereafter, with periodic written reports submitted to
        Landlord, prosecute or complete with due diligence and dispatch the
        curing of such default, as to which time is of the essence.

        (4) GENERAL ASSIGNMENT. A general assignment by Tenant for the benefit
        of creditors.

        (5) BANKRUPTCY. The filing of any voluntary petition in bankruptcy by
        Tenant, or the filing of an involuntary petition by Tenant's creditors,
        which involuntary petition remains undercharged for a period of thirty
        (30) days. If under applicable law, the trustee in bankruptcy or Tenant
        has the right to affirm this Lease and continue to perform the
        obligations of Tenant hereunder, such trustee or Tenant shall, in such
        time period as may be permitted by the bankruptcy court having
        jurisdiction, cure all defaults of Tenant hereunder outstanding as of
        the date of the affirmance of this Lease and provide to Landlord such
        adequate assurances as may be necessary to ensure Landlord of the
        continued performance of Tenant's obligations under this Lease.

                                       16
<PAGE>   81

        (6) RECEIVERSHIP. The employment of a receiver to take possession of
        substantially all of Tenant's assets or the Premises, if such
        appointment remains undismissed or undischarged for a period of fifteen
        (15) days after the order therefor.

        (7) ATTACHMENT. The attachment, execution or other judicial seizure of
        all or substantially all of Tenant's assets or Tenant's leasehold of the
        Premises, if such attachment or other seizure remains undismissed or
        undischarged for a period of fifteen (15) days after the levy thereof.

        (8) INSOLVENCY. The admission by Tenant in writing of its inability to
        pay its debts as they become due.

B. REMEDIES UPON DEFAULT.

        (1) TERMINATION. In the event of the occurrence of any event of default,
        Landlord shall have the right to give a written termination notice to
        Tenant, and on the date specified in such notice, Tenant's right to
        possession shall terminate, and this Lease shall terminate unless on or
        before such date all Rent in arrears and all costs and expenses incurred
        by or on behalf of Landlord hereunder shall have been paid by Tenant and
        all other events of default of this Lease by Tenant at the time existing
        shall have been fully remedied to the satisfaction of Landlord. At any
        time after such termination, Landlord may recover possession of the
        Premises or any part thereof and expel and remove therefrom Tenant and
        any other person occupying the same, including any subtenant or
        subtenants notwithstanding Landlord's consent to any sublease, by any
        lawful means, and again repossess and enjoy the Premises without
        prejudice to any of the remedies that Landlord may have under this
        Lease, or at law or equity by any reason of Tenant's default or of such
        termination. Landlord hereby reserves the right, but shall not have the
        obligation, to recognize the continued possession of any subtenant. The
        delivery or surrender to Landlord by or on behalf of Tenant of keys,
        entry codes, or other means to bypass security at the Premises shall not
        terminate this Lease.

        (2) CONTINUATION AFTER DEFAULT. Even though an event of default may have
        occurred, this Lease shall continue in effect for so long as Landlord
        does not terminate Tenant's right to possession under Paragraph 26.B.(1)
        hereof, and Landlord may enforce all of Landlord's rights and remedies
        under this Lease and at law or in equity, including without limitation,
        the right to recover Rent as it becomes due, and Landlord, without
        terminating this Lease, may exercise all of the rights and remedies of a
        landlord under Section 1951.4 of the Civil Code of the State of
        California or any successor code section. Acts of maintenance,
        preservation or efforts to lease the Premises or the appointment of a
        receiver under application of Landlord to protect Landlord's interest
        under this Lease or other entry by Landlord upon the Premises shall not
        constitute an election to terminate Tenant's right to possession.

        (3) INCREASED SECURITY DEPOSIT. If Tenant is in default under Paragraph
        26.A.(2) hereof and such default remains uncured for ten (10) days after
        such occurrence or such default occurs more than three times in any
        twelve (12) month period, Landlord may require that Tenant increase the
        Security Deposit to the amount of three times the current month's Rent
        at the time of the most recent default.

C. DAMAGES AFTER DEFAULT. Should Landlord terminate this Lease pursuant to the
provisions of Paragraph 26.B.(1) hereof, Landlord shall have the rights and
remedies of a Landlord provided by Section 1951.2 of the Civil Code of the State
of California, or any successor code sections. Upon such termination, in
addition to any other rights and remedies to which Landlord may be entitled
under applicable law or at equity, Landlord shall be entitled to recover from
Tenant: (1) the worth at the time of award of the unpaid Rent and other amounts
which had been earned at the time of termination, (2) the worth at the time of
award of the amount by which the unpaid Rent and other amounts that would have
been earned after the date of termination until the time of award exceeds the
amount of such Rent loss that Tenant proves could have been reasonably avoided;
(3) the worth at the time of award of the amount by which the unpaid Rent and
other amounts for the balance of the Term after the time of award exceeds the
amount of such Rent loss that the Tenant proves could be reasonably avoided; and
(4) any other amount and court costs necessary to compensate Landlord for all
detriment proximately caused by Tenant's failure to perform Tenant's obligations
under this Lease or which, in the ordinary course of things, would be likely to
result therefrom. The "worth at the time of award" as used in (1) and (2) above
shall be computed at the Applicable Interest Rate (defined below). The "worth at
the time of award" as used in (3) above shall be computed by discounting such
amount at the Federal Discount Rate of the Federal Reserve Bank of San Francisco
at the time of award plus one percent (1%).

D. LATE CHARGE. In addition to its other remedies, Landlord shall have the right
without notice or demand to add to the amount of any payment required to be made
by Tenant hereunder, and which is not paid and received by Landlord on or before
the fifth business day of each calendar month, an amount equal to (i) two and
one-half percent (2.5%) for the first late payment during any calendar year, and
(ii) five percent (5%) for the second and subsequent late payment during any
calendar year of the delinquency for each month or portion thereof that the
delinquency remains outstanding to compensate Landlord for the loss of the use
of the amount not paid and the administrative costs caused by the delinquency,
the parties agreeing that Landlord's damage by virtue of such delinquencies
would be extremely difficult and impracticable to compute and the amount stated
herein represents a reasonable estimate thereof, provided, however, that on one
(1) occasion during any calendar year of the Term, Landlord shall give Tenant
written notice of such late payment and Tenant shall have a period of five (5)
calendar days thereafter in which to make such payment before any late charge
shall be assessed. Any waiver by Landlord of any late charges or failure to
claim the same shall not constitute a waiver of other late charges or any other
remedies available to Landlord.

E. INTEREST. Interest shall accrue on all sums not paid when due hereunder at
the lesser of fourteen percent (14%) per annum or the maximum interest rate
allowed by law ("APPLICABLE INTEREST RATE") from the due date until paid.

F. REMEDIES CUMULATIVE. All rights, privileges and elections or remedies of the
parties are cumulative and not alternative, to the extent permitted by law and
except as otherwise provided herein.

G. LANDLORD'S DEFAULT. Landlord shall not be in default hereunder unless
Landlord fails to perform any material obligation required of Landlord under the
terms of this Lease within a reasonable time, but in no event later than sixty
(60) days after written notice by Tenant to Landlord, subject to Paragraph 35 of
this Lease, specifying the nature of Landlord's failure to perform. If, however,
the nature of Landlord's obligation is such that more than sixty (60) days are
reasonably required for performance, then Landlord shall not be in default
hereunder if Landlord commences performance within such sixty (60) day period,
subject to Paragraph 35 of this Lease, and thereafter diligently prosecutes such
cure to completion. If Landlord at the expiration of such notice and cure
periods has failed to cure such default, then, subject to the exculpatory
provisions of this Paragraph 26, Tenant may pursue any of its legal or equitable
remedies, but Tenant shall have no right to otherwise terminate this Lease.
Notwithstanding the foregoing, nothing contained in this Paragraph 26.G. shall
be deemed to expand Tenant's remedies under circumstances where particular
provisions of this Lease expressly provide for an available remedy and where
such available remedies are so set forth they shall be deemed Tenant's exclusive
remedy.

                                    27. LIENS

Tenant shall at all times keep the Premises and the Project free from liens
arising out of or related to work or services performed, materials or supplies
furnished or obligations incurred by or on behalf of Tenant or in connection
with work made, suffered or done by or on behalf of Tenant in or on the Premises
or Project. If Tenant shall not, within ten (10) days following the imposition
of any such lien, cause the same to be released of record by payment or posting
of a proper bond, Landlord shall have, in addition to all other remedies
provided herein and by law, the right, but not the obligation, to cause the same
to be released by such means as Landlord shall deem proper, including payment of
the claim giving rise to such lien. All sums paid by Landlord on behalf of
Tenant and all expenses incurred by Landlord in connection therefor shall be
payable to Landlord by Tenant on demand with interest at the Applicable Interest
Rate as Additional Rent. Landlord shall have the right at all times to post and
keep posted on the Premises any notices permitted or required by law, or which
Landlord shall deem proper, for the protection of Landlord, the Premises, the
Project and any other party having an interest therein, from mechanics' and
materialmen's liens, and Tenant shall give Landlord not less than ten (10)
business days prior written notice of the commencement of any work in the
Premises or Project which could lawfully give rise to a claim for mechanics' or
materialmen's liens to permit Landlord to post and record a timely notice of
non-responsibility, as Landlord may elect to proceed or as the law may from time
to time provide, for which purpose, if Landlord shall so determine, Landlord may
enter the Premises. Tenant shall not remove any such notice posted by Landlord
without Landlord's consent, and in any event not before completion of the work
which could lawfully give rise to a claim for mechanics' or materialmen's liens.

                                28. SUBSTITUTION

A.

                            29. TRANSFERS BY LANDLORD

In the event of a sale or conveyance by Landlord of the Building or a
foreclosure by any creditor of Landlord, the same shall operate to release
Landlord from any liability upon any of the covenants or conditions, express or
implied, herein contained in favor of Tenant, to the extent required to be
performed after the passing of title to Landlord's successor-in-interest. In
such event, Tenant agrees to look solely to the responsibility of the
successor-in-interest of Landlord under this Lease with respect to the
performance of the covenants and duties of "Landlord" to be performed after the
passing of title to Landlord's successor-in-interest provided such
successor-in-interest assumes in writing Landlord's duties, obligations or
liabilities hereunder. This Lease shall not be affected by any such sale and
Tenant agrees to attorn to the purchaser or assignee. Landlord's
successor(s)-in-interest shall not have liability to Tenant with respect to the
failure to perform any of the obligations of "Landlord," to the extent required
to be performed prior to the date such successor(s)-in-interest became the owner
of the Building.

                     30. RIGHT OF LANDLORD TO PERFORM TENANT'S COVENANTS

All covenants and agreements to be performed by Tenant under any of the terms of
this Lease shall be performed by Tenant at Tenant's sole cost and expense and
without any abatement of Rent, except as otherwise expressly set forth herein.
If Tenant shall fail to pay any sum of money, other than Base Rent, required to
be paid by Tenant hereunder or shall fail to perform any other act on Tenant's
part to be performed hereunder, including Tenant's obligations under Paragraph
11 hereof, and such failure shall continue for fifteen (15) days after notice
thereof by Landlord, in addition to the other rights and remedies of Landlord,
Landlord may make any such payment and perform any such act on Tenant's part. In
the case of an emergency, no prior notification by Landlord shall be required.
Landlord may take such actions without any obligation and without releasing
Tenant from any of Tenant's obligations. All sums so paid by Landlord and all
incidental costs incurred by Landlord and interest thereon at the Applicable
Interest Rate, from the date of payment by Landlord, shall be paid to Landlord
on demand as Additional Rent.

                                   31. WAIVER

If either Landlord or Tenant waives the performance of any term, covenant or
condition contained in this Lease, such waiver shall not be deemed to be a
waiver of any subsequent breach of the same or any other term, covenant or
condition contained herein, or constitute a course of dealing contrary to the
expressed terms of this Lease. The acceptance of Rent by Landlord shall not
constitute a waiver of any preceding breach by Tenant of any term, covenant or
condition of this Lease, regardless of Landlord's knowledge of such preceding
breach at the time Landlord accepted such Rent. Failure by Landlord to enforce
any of the terms, covenants or conditions of this Lease for any length of time
shall not be deemed to waive or decrease the right of Landlord to insist
thereafter upon strict performance by Tenant. Waiver by Landlord of any term,
covenant or condition contained in this Lease may only be made by a written
document signed by Landlord, based upon full knowledge of the circumstances.

                                   32. NOTICES

Each provision of this Lease or of any applicable governmental laws, ordinances,
regulations and other requirements with reference to sending, mailing, or
delivery of any notice or the making of any payment by Landlord or Tenant to the
other shall be deemed to be complied with when and if the following steps are
taken:

A. RENT. All Rent and other payments required to be made by Tenant to Landlord
hereunder shall be payable to Landlord at Landlord's Remittance Address set
forth in the Basic Lease Information, or at such other address as Landlord may
specify from time to time by written notice delivered in accordance herewith.
Tenant's obligation to pay Rent and any other amounts to Landlord under the
terms of this Lease shall not be deemed satisfied until such Rent and other
amounts have been actually received by Landlord.

B. OTHER. All notices, demands, consents and approvals which may or are required
to be given by either party to the other hereunder shall be in writing and
either personally delivered, sent by commercial overnight courier, mailed,
certified or registered, postage prepaid or sent by facsimile with confirmed
receipt (and with an original sent by commercial overnight courier), and in each
case addressed to the party to be notified at the Notice Address for such party
as specified in the Basic Lease Information or to such other place as the party
to be notified may from time to time designate by at least fifteen (15) days
notice to the notifying party. Notices shall be deemed served upon receipt or
refusal to accept delivery.

                                       18
<PAGE>   83

C. REQUIRED NOTICES. Tenant shall immediately notify Landlord in writing of any
notice of a violation or a potential or alleged violation of any Regulation that
relates to the Premises or the Project, or of any inquiry, investigation,
enforcement or other action that is instituted or threatened by any governmental
or regulatory agency against Tenant or any other occupant of the Premises, or
any claim that is instituted or threatened by any third party that relates to
the Premises or the Project.

                               33. ATTORNEYS' FEES

If Landlord places the enforcement of this Lease, or any part thereof, or the
collection of any Rent due, or to become due hereunder, or recovery of
possession of the Premises in the hands of an attorney, Tenant shall pay to
Landlord, upon demand, Landlord's reasonable attorneys' fees and court costs,
whether incurred at trial, appeal or review. In any action which Landlord or
Tenant brings to enforce its respective rights hereunder, the unsuccessful party
shall pay all costs incurred by the prevailing party including reasonable
attorneys' fees, to be fixed by the court, and said costs and attorneys' fees
shall be a part of the judgment in said action.

                           34. SUCCESSORS AND ASSIGNS

This Lease shall be binding upon and inure to the benefit of Landlord, its
successors and assigns, and shall be binding upon and inure to the benefit of
Tenant, its successors, and to the extent assignment is approved by Landlord as
provided hereunder, Tenant's assigns.

                                35. FORCE MAJEURE

If performance by a party of any portion of this Lease is made impossible by any
prevention, delay, or stoppage caused by strikes, lockouts, labor disputes, acts
of God, inability to obtain services, labor, or materials or reasonable
substitutes for those items, government actions, civil commotions, fire or other
casualty, or other causes beyond the reasonable control of the party obligated
to perform, performance by that party for a period equal to the period of that
prevention, delay, or stoppage is excused. Tenant's obligation to pay Rent,
however, is not excused by this Paragraph 35.

                            36. SURRENDER OF PREMISES

Tenant shall, upon expiration or sooner termination of this Lease, surrender the
Premises to Landlord in the same condition as existed on the date Tenant
originally took possession thereof (reasonable wear and tear, casualty damage
and acts of God excepted), including, but not limited to, all holes in walls
repaired, all HVAC equipment in operating order and in good repair, and all
floors cleaned, waxed, and free of any Tenant-introduced marking or painting,
all to the reasonable satisfaction of Landlord. Tenant shall remove all of its
debris from the Project. At or before the time of surrender, Tenant shall comply
with the terms of Paragraph 12.A. hereof with respect to Alterations to the
Premises and all other matters addressed in such Paragraph. If the Premises are
not so surrendered at the expiration or sooner termination of this Lease, the
provisions of Paragraph 25 hereof shall apply. All keys to the Premises or any
part thereof shall be surrendered to Landlord upon expiration or sooner
termination of the Term. Tenant shall meet with Landlord for a joint inspection
of the Premises fifteen (15) days prior to vacating, but nothing contained
herein shall be construed as an extension of the Term or as a consent by
Landlord to any holding over by Tenant. In the event of Tenant's failure to give
such notice or participate in such joint inspection, Landlord's inspection at or
after Tenant's vacating the Premises shall conclusively be deemed correct for
purposes of determining Tenant's responsibility for repairs and restoration. Any
delay caused by Tenant's failure to carry out its obligations under this
Paragraph 36 beyond the term hereof, shall constitute unlawful and illegal
possession of Premises under Paragraph 25 hereof.

                                37. MISCELLANEOUS

A. GENERAL. The term "Tenant" or any pronoun used in place thereof shall
indicate and include the masculine or feminine, the singular or plural number,
individuals, firms or corporations, and their respective successors, executors,
administrators and permitted assigns, according to the context hereof.

B. TIME. Time is of the essence regarding this Lease and all of its provisions.

C. CHOICE OF LAW. This Lease shall in all respects be governed by the laws of
the State of California.

D. ENTIRE AGREEMENT. This Lease, together with its Exhibits, addenda and
attachments and the Basic Lease Information, contains all the agreements of the
parties hereto and supersedes any previous negotiations. There have been no
representations made by the Landlord or understandings made between the parties
other than those set forth in this Lease and its Exhibits, addenda and
attachments and the Basic Lease Information.

E. MODIFICATION. This Lease may not be modified except by a written instrument
signed by the parties hereto. Tenant accepts the area of the Premises as
specified in the Basic Lease Information as the approximate area of the Premises
for all purposes under this Lease, and acknowledges and agrees that no other
definition of the area (rentable, usable or otherwise) of the Premises shall
apply. Tenant shall in no event be entitled to a recalculation of the square
footage of the Premises, rentable, usable or otherwise, and no recalculation, if
made, irrespective of its purpose, shall reduce Tenant's obligations under this
Lease in any manner, including without limitation the amount of Base Rent
payable by Tenant or Tenant's Proportionate Share of the Building and of the
Project.

F. SEVERABILITY. If, for any reason whatsoever, any of the provisions hereof
shall be unenforceable or ineffective, all of the other provisions shall be and
remain in full force and effect.

G. RECORDATION. Tenant shall have the right to record a mutually acceptable
short form memorandum hereof, provided that Tenant agrees upon the expiration or
earlier termination of this Lease to execute and deliver to Landlord a quitclaim
deed terminating said short form memorandum.

H. EXAMINATION OF LEASE. Submission of this Lease to Tenant does not constitute
an option or offer to lease and this Lease is not effective otherwise until
execution and delivery by both Landlord and Tenant.

I. ACCORD AND SATISFACTION. No payment by Tenant of a lesser amount than the
total Rent due nor any endorsement on any check or letter accompanying any check
or payment of Rent shall be deemed an accord and satisfaction of full payment of
Rent, and Landlord may accept such payment without prejudice to Landlord's right
to recover the balance of such Rent or to pursue other remedies. All offers by
or on behalf of Tenant of accord and satisfaction are hereby rejected in
advance.

J. EASEMENTS. Landlord may grant easements on the Project and dedicate for
public use portions of the Project without Tenant's consent; provided that no
such grant or dedication shall materially interfere with Tenant's Permitted Use
of the Premises. Upon Landlord's

                                       19
<PAGE>   84

request, Tenant shall execute, acknowledge and deliver to Landlord documents,
instruments, maps and plats reasonably necessary to effectuate Tenant's
covenants hereunder.

K. DRAFTING AND DETERMINATION PRESUMPTION. The parties acknowledge that this
Lease has been agreed to by both the parties, that both Landlord and Tenant have
consulted with attorneys with respect to the terms of this Lease and that no
presumption shall be created against Landlord because Landlord drafted this
Lease. Except as otherwise specifically set forth in this Lease, with respect to
any consent, determination or estimation of Landlord required or allowed in this
Lease or requested of Landlord, Landlord's consent, determination or estimation
shall be given or made solely by Landlord in Landlord's good faith and
reasonable opinion.

L. EXHIBITS. The Basic Lease Information, and the Exhibits, addenda and
attachments attached hereto are hereby incorporated herein by this reference and
made a part of this Lease as though fully set forth herein.

M. NO LIGHT, AIR OR VIEW EASEMENT. Any diminution or shutting off of light, air
or view by any structure which may be erected on lands adjacent to or in the
vicinity of the Building shall in no way affect this Lease or impose any
liability on Landlord.

N. NO THIRD PARTY BENEFIT. This Lease is a contract between Landlord and Tenant
and nothing herein is intended to create any third party benefit.

O. QUIET ENJOYMENT. Upon payment by Tenant of the Rent, and upon the observance
and performance of all of the other covenants, terms and conditions on Tenant's
part to be observed and performed, Tenant shall peaceably and quietly hold and
enjoy the Premises for the term hereby demised without hindrance or interruption
by Landlord or any other person or persons lawfully or equitably claiming by,
through or under Landlord, subject, nevertheless, to all of the other terms and
conditions of this Lease. Landlord shall not be liable for any hindrance,
interruption, interference or disturbance by other tenants or third persons, nor
shall Tenant be released from any obligations under this Lease because of such
hindrance, interruption, interference or disturbance.

P. COUNTERPARTS. This Lease may be executed in any number of counterparts, each
of which shall be deemed an original.

Q. MULTIPLE PARTIES. If more than one person or entity is named herein as
Tenant, such multiple parties shall have joint and several responsibility to
comply with the terms of this Lease.

R. PRORATIONS. Any Rent or other amounts payable to Landlord by Tenant hereunder
for any fractional month shall be prorated based on a month of 30 days. As used
herein, the term "fiscal year" shall mean the calendar year or such other fiscal
year as Landlord may deem appropriate.

S. OPERATING POLICIES. During the Term of this Lease, Landlord shall operate and
maintain the Building in a manner generally consistent with other comparable
first-class business park projects in San Diego County.

T. LANDLORD'S COVENANT. In connection with the exercise by Landlord of the
rights and reservations granted or afforded by this Lease, Landlord hereby
covenants and agrees to:

        (1)  use its reasonable good faith efforts to avoid taking any actions
             (excepting any actions to comply with Regulations) which may
             materially adversely affect Tenant's use of or normal business
             operations within the Premises;

        (2)  use its reasonable good faith efforts to provide Tenant with prior
             written notice of any such actions by Landlord (excepting any
             actions to comply with Regulations) which may materially adversely
             affect Tenant's use of or normal business operations within the
             Premises and at least forty-eight (48) hours prior written notice
             of any scheduled work to be performed by Landlord which may
             materially adversely interfere with Tenant's normal business
             operations; it being understood, however, that the giving of such
             prior written notice may be impossible or impractical under
             emergency circumstances;

        (3)  in a manner consistent with the prudent and efficient operation of
             the Project, to reasonable coordinate and reasonably cooperate with
             Tenant to reasonably minimize any cessation or degradation of
             Tenant's use of or normal business operations within the Premises;
             and

        (4)  use its reasonable good faith efforts to perform all work in an
             expeditious and workmanlike manner and to restore access to the
             Premises and the availability of Building services as soon as
             reasonably practicable.

Notwithstanding anything contained in this Paragraph 37.T. to the contrary, in
no event shall Landlord be liable or responsible for any consequential or
exemplary damages.

U. CONSENT/DUTY TO ACT REASONABLY. Except for the provisions of this Lease which
expressly grant a party the right to act in its sole discretion, whereupon in
each such case, Landlord's and Tenant's duty is to act in good faith (but shall
not otherwise be subject to a "reasonableness" standard) (i) any time the
consent of Landlord or Tenant is required, such consent shall not be
unreasonably withheld, delayed or conditioned, and (ii) whenever this Lease
grants Landlord or Tenant the right to take action, exercise discretion,
establish rules and regulations or make allocations or other determinations,
Landlord and Tenant shall act reasonably and in good faith and take no action
which might result in the frustration of the other party's reasonable
expectations concerning the benefits to be enjoyed under this Lease.

V. YEAR 2000 COMPLIANCE. Landlord hereby represents, warrants and covenants to
the best of its knowledge to Tenant that all of the Project's mechanical,
electrical, elevator, fire and life safety systems (the "Building Systems") will
operate on and after January 1, 2000 without normal operation being impaired by
dates in and after the year 2000. At Tenant's request, Landlord shall provide
Tenant with reasonably satisfactory evidence of the Building Systems' compliance
with the foregoing.

                            38. ADDITIONAL PROVISIONS

A. BASE RENT. The monthly Base Rent during the initial Term shall be as follows:

</TABLE>

B. RENEWAL OPTION. Provided Tenant is not, and has not been, in material default
of any of its obligations under this Lease or any other lease Tenant may have in
the Project, after expiration of all applicable grace, notice and cure periods,
it shall have an option to renew this Lease for the Premises in "as is"
condition for two (2) five (5) year periods on the same terms and conditions as
set forth in this Lease except that the Base Rent of each option period shall be
the then fair prevailing market rate rental for comparable space of at least one
hundred thousand (100,000) square feet at comparable buildings within the
Eastgate Technology Park and University Towne Centre areas, as defined and
determined by Subparagraph 38.B(1) and/or 38 B.(2) below. In no event will the
Base Rent for each option period be less than that of the previous period.
Tenant shall give Landlord written notice to exercise its option at least
eighteen (18) months but not more than fifteen (15) months prior to the
expiration of the Term, or extended Term.

        Notwithstanding anything to the contrary herein contained, Tenant's
right to extend the Term by exercise of the foregoing option shall be
conditioned upon the following: (a) at the time of the exercise of the option,
and at the time of the commencement of the extended Term, Tenant shall be in
possession of and occupying at least seventy-five percent (75%) of the Premises,
and at least seventy-five percent (75%) of all other premises under any other
leases Tenant may have in the Project, for the conduct of its business therein
and the same shall not be occupied by any assignee, subtenant, or licensee; and
(b) the notice of exercise shall constitute a representation, by commencement of
the extended Term, that Tenant does not intend to seek to assign more than
twenty-five percent (25%) of the Lease, or sublet more than twenty-five percent
(25%) of any other premises under any other leases Tenant may have in the
Project.

(1) "Fair Market Rental" shall mean the rate being charged to tenants recently
    renewing existing leases for comparable space in buildings within the
    Eastgate Technology Park and University Towne Centre areas, taking into
    consideration all relevant factors, including but not limited to, the
    following: size, location, floor level, proposed term of the lease, expense
    stops, extent of building services to be provided, and the time that the
    rental rate under consideration is to become effective. Fair Market Rental
    as of the commencement of each option period shall be determined by Landlord
    with written notice (the "Notice") given to Tenant not later than thirty
    (30) days after the receipt of the option notice, subject to Tenant's right
    to arbitration as provided in Subparagraph 38.B(2) below. Failure on the
    part of Tenant to demand arbitration within thirty (30) days after receipt
    of the Notice from Landlord shall bind Tenant to the Fair Market Rental as
    determined by Landlord. Notwithstanding anything to contrary herein,
    Tenant's right to arbitrate shall conclude no later than ninety (90) days
    after the date of the Notice.

(2) If Tenant disputes the amount claimed by Landlord as Fair Market Rental,
    Tenant may require that Landlord submit the dispute to arbitration. The
    arbitration shall be conducted and determined in San Diego, California, in
    accordance with the then prevailing rules of the American Arbitration
    Association or its successor for arbitration of commercial disputes, except
    that the procedures mandated by such rules shall be modified as follows:

    (a) Tenant shall make demand for arbitration in writing within thirty (30)
    days after service of the Notice, specifying therein the name and address of
    the person to act as the arbitrator on Tenant's behalf. The arbitrator shall
    be a M.A.I. designated and independent real estate appraiser with at least
    ten (10) years full-time commercial appraisal experience who is familiar
    with the Fair Market Rental of first-class business park space in San Diego
    County. (In the event M.A.I. appraisers are no longer available, a
    comparable designation with at least ten (10) years experience with
    commercial property appraisal in San Diego County will be acceptable.)
    Failure on the part of Tenant to make the timely and proper demand for such
    arbitration shall constitute a waiver of the right thereto. Within ten (10)
    business days after the service of the demand for arbitration, Landlord
    shall give notice to Tenant specifying the name and address of the person
    designated by Landlord to act as arbitrator on its behalf, which arbitrator
    shall be similarly qualified. If Landlord fails to notify Tenant of the
    appointment of its arbitrator, within or by the time specified, then the
    arbitrator appointed by Tenant shall be the arbitrator to determine the Fair
    Market Rental for the Premises.

    (b) If two arbitrators are chosen pursuant to Subparagraph 38.B.(2)(a)
    above, the arbitrators so chosen shall meet within ten (10) business days
    after the second arbitrator is appointed and shall appoint a third
    arbitrator, who shall be a competent and impartial person with
    qualifications similar to those required of the first two arbitrators
    pursuant to Subparagraph 38.B(2)(a) above. If they are unable to agree upon
    such appointment within five (5) business days after expiration of such ten
    (10) day period, the third arbitrator shall be selected by the parties
    themselves. If the parties do not agree on the third arbitrator within five
    (5) business days after expiration of the foregoing five (5) business day
    period, then either party, on behalf of both, may request appointment of
    such a qualified arbitrator by (i) the majority of board members of the San
    Diego County Chapter of M.A.I. appraisers, or (ii) the chief arbitrator of
    the San Diego County Chapter of the American Arbitration Association. The
    three arbitrators shall decide the dispute, if has not been previously
    resolved, by following the procedures set forth in Subparagraph 38.B(2)(c)
    below. Each party shall pay the fees and expenses of its respective
    arbitrator and both shall share the fees and expenses of the third
    arbitrator. Attorneys' fees and expenses of counsel and of witnesses or
    other experts for the respective parties shall be paid by the respective
    party engaging such counsel or calling such witnesses or other experts.

    (c) The Fair Market Rental shall be fixed by the three arbitrators in
    accordance with the following procedures. Each of the arbitrators selected
    by the parties shall state, in writing, his or her determination of the Fair
    Market Rental supported by the reasons therefor and shall make counterpart
    copies for each of the other arbitrators. The arbitrators shall arrange for
    a simultaneous exchange of such proposed resolutions within ten (10)
    business days after appointment of the third arbitrator. If either
    arbitrator fails to deliver to the other arbitrators his or her
    determination within such ten (10) business day period, then the
    determination of the other arbitrator shall be final and binding upon the
    parties. The role of the third arbitrator shall be to select which of the
    two proposed resolutions most closely approximates his or her determination
    of Fair Market Rental. The third arbitrator shall have no right to propose a
    middle ground or any modification of either of the two proposed resolutions.
    The resolution he or she chooses as the most closely approximating his or
    her determination of the Fair Market Rental shall constitute the decision of
    the arbitrators and shall be final and binding upon the parties. If either
    party fails to pay its share of the fees of the third arbitrator within
    thirty (30) days after receipt of an

                                       21
<PAGE>   86

    invoice, or fails to execute and deliver any documents reasonably required
    by the third arbitrator within thirty (30) days after receipt thereof, then
    the Fair Market Rental shall be determined solely by the arbitrator selected
    by the other party.

(d) In the event of a failure, refusal or inability of any arbitrator to act,
    his or her successor shall be appointed by him or her, but in the case of
    the third arbitrator, his or her successor shall be appointed in the same
    manner as that set forth herein with respect to the appointment of the
    original third arbitrator. The arbitrators shall attempt to decide the issue
    within ten (10) business days after the appointment of the third arbitrator.
    Any decision in which the arbitrator appointed by Landlord and the
    arbitrator appointed by Tenant concur shall be binding and conclusive upon
    the parties, except that such arbitrators shall not attempt by themselves to
    mutually ascertain the Fair Market Rental and any such determination, in a
    manner other than that provided for in Subparagraph 38.B(2)(c) hereof, shall
    not be binding on the parties.

C. ALTERNATIVE TERM EXPIRATION DATE. Subject to a CERTAIN lease DATED AUGUST

occupancy and commencing the payment of Rent, Tenant shall have the right to
alter the Term Expiration Date upon written notice to Landlord no sooner than
twenty-four (24) months and no later than eighteen (18) months prior to the
scheduled Term Expiration Date. This alteration of the Premises' Term Expiration
Date shall consist of exchanging the term expiration date of the PHASE A

Rent to the Base Rent for the Premises as they become due during the initial
months of the Term.

E. TERMINATION RIGHTS. Notwithstanding anything to the contrary contained in
this Lease, if Tenant is notified by Landlord, or Tenant becomes aware and
notifies Landlord of the occurrence of a Trigger Event (defined below), and such
Trigger Event materially adversely affects the operation of Tenant's normal
business in, use of, prevents Tenant's reasonable access to the Premises, and

right to terminate this Lease, upon thirty (30) days' prior written notice sent
to Landlord within a period of sixty (60) days following the later of the
occurrence of the Trigger Event or Tenant's receipt (or giving) of notice
thereof (such notice, in the case of a Trigger Event described in subparagraphs
(1) and (2) below, to contain a reasonably detailed description of the scope of
the Trigger Event). Notwithstanding the forgoing, Tenant shall not have a right
to so terminate this Lease if Landlord takes action within said sixty (60) day
period (but no later than the expiration of the thirty (30) day period) which
will result in the restoration of the Tenant's normal business operations in,
Tenant's reasonable access to, and Tenant's use of the Premises in a condition
suitable for the efficient conduct of Tenant's normal business (including,
without limitation, utilities required or necessary for the operation of
Tenant's normal business in the Premises) prior to the end of the Maximum
Restoration Period.

As used herein, the term "TRIGGER EVENT" shall mean and refer to:

        (1) continuous interruption of electrical, water, telecommunication,
    telephone, gas, sewer or other essential utility services used or required

    condition in, on or around the land, Building, Project, common areas or
    Premises, which, taking into account applicable environmental laws, either
    is unlawful or represents a significant health risk to occupants of the
    Premises, excepting those Hazardous Materials either:

        (a)  used by Tenant's contractor in the construction of Alterations in
             the Premises; or

        (b)  generated by Tenant or brought onto or into the Project, Building,
             Premises or common areas, by Tenant as more particularly described
             in Paragraph 4.D. of this Lease.

renewal or extensions thereof), Tenant shall have the right, without payment of
any fee or charge therefor, to install and operate, for Tenant's personal use
only, one (1) microwave transmitter-receiver or satellite dish (the "Satellite
Dish") on one Building rooftop (the "Designated Building") of a weight, height,
and width reasonably acceptable to Landlord. Landlord shall not withhold its
consent to the installation of a Satellite Dish reasonably comparable to those
installed within the Project. Tenant's rights pursuant to this Paragraph 38.G.

<PAGE>   87

        (2) Prior to installing the Satellite Dish, Tenant must notify Landlord
        in writing, specifying the type, character, size, location, amount of
        space required, installation details and electrical requirements.
        Landlord in its reasonable discretion shall approve of said
        specifications of the Satellite Dish within ten (10) days following
        receipt of Tenant's written request to install a Satellite Dish on the
        roof of the Designated Building.

        (3) Tenant shall pay any federal, state and local taxes applicable to
        the installation and use of the Satellite Dish and Tenant shall procure,
        maintain and pay for and obtain all fees, permits and governmental
        agency licenses necessary in connection with all installation,
        maintenance and operation of the Satellite Dish; provided, however, that
        Landlord shall reasonably cooperate with the efforts of Tenant in
        connection with any governmental application or filing required thereby.
        Tenant shall reimburse Landlord for any actual costs Landlord may incur
        to assist Tenant as detailed in the preceding sentence.

        (4) Tenant shall be permitted, at its sole cost, expense and
        responsibility, but without separate charge other than any charges

        chaseway of the Designated Building in an area in the core of the
        Designated Building, one (1) non-dedicated conduit for its cabling use
        (and the use of the Satellite Dish and cable contained therein
        connecting to such Building's roof for operation of Tenant's Satellite
        Dish). All installations required in connection with the Satellite Dish
        shall be made by means of conduits, wires or cables that will pass
        through existing openings in the walls or roof decks of the Designated
        Building, and all cable and wires located on the roof of the Designated
        Building used in connection with Satellite Dish shall be covered by
        rust-proof conduits and attachments. In no event shall any of Tenant's
        installations be made through the roof surface or membrane of the
        Designated Building without the prior written consent of Landlord, which
        consent may be withheld in Landlord's sole and absolute discretion. The
        installation of the Satellite Dish shall be subject to Landlord's review
        and approval and shall conform to the engineering standards commonly
        used for installing similar satellite dishes within the Project.

        (5) Tenant, at its sole cost, expense, and responsibility, will comply
        with all present and future laws, and with any reasonable requirements
        of any applicable fire rating bureau relating to the maintenance, use,
        installation and operation of the Satellite Dish. Tenant shall install,
        maintain and operate all of its equipment used in connection with the
        Satellite Dish in conformity with all Regulations of all government
        agencies having jurisdiction over the installation, use and operation of
        the Satellite Dish, including, without limitation, the Federal Aviation
        Administration and the Federal Communications Commission; provided,
        however, that if compliance with such laws or regulations would require
        a change in the size, configuration or location of the Satellite Dish,
        such changes shall be subject to Landlord's prior written consent.

        (6) Prior to the expiration or earlier termination of the Term of this
        Lease, or any extended Term, Tenant shall remove the Satellite Dish and
        all wires and cables used in connection with the Satellite Dish, and
        shall restore and repair all damage to the Designated Building
        occasioned by the installation, maintenance or removal of the Satellite
        Dish. If Tenant fails to timely complete such removal, restoration and
        repair, all sums incurred by Landlord to complete such work shall be
        paid by Tenant to Landlord upon demand.

        (7) Landlord makes no representations or warranties whatsoever with
        respect to the fitness or suitability of the Designated Building for the
        installation, maintenance and operation of the Satellite Dish,
        including, without limitation, with respect to the quality and clarity
        or any receptions and transmissions to or from the Satellite Dish and
        the presence of any interference with such signals, whether emanating
        from the Designated Building or otherwise. Landlord shall permit Tenant
        to have reasonable access to such other parts of the Designated Building
        as are open to the public or for which access is otherwise reasonably
        necessary in order to install, maintain and operate the Satellite Dish.
        Notwithstanding anything set forth in this Paragraph 38.G. to the
        contrary, if Landlord reasonably determines that the installation of the
        Satellite Dish will be detrimental to the design or structural soundness
        of the Designated Building or will create risk of injury or damage to
        persons or property, Tenant shall not be permitted to install said
        Satellite Dish.

        (8) Tenant must notify Landlord in writing prior to the scheduled date
        Tenant proposes to install the Satellite Dish on the roof of the
        Designated Building in order to make arrangements for the movement of
        materials needed in connection with the installation of the Satellite
        Dish.

        (9) Tenant shall provide at its sole cost, expense and responsibility,
        adequate maintenance personnel in order to ensure the safe operation of
        the Satellite Dish. In addition, Tenant shall install, maintain and
        operate all of its equipment used in connection with the Satellite Dish
        in a fashion and manner so as not to interfere with the use and
        operation of any: (a) other televisions or radio equipment in the
        Designated Building; (b) present or future electronic control system for
        any operating services or the operation of the elevators in any Building
        within the Project; (c) other transmitting, receiving or master
        television, telecommunications or microwave antenna equipment currently
        located on the roof of the Designated Building or other buildings within
        the Project; or (d) any radio communication system now used by Landlord
        and/or other tenants of the Project. In addition, Tenant shall use its
        commercially reasonable efforts to ensure that Tenant will not interfere
        with any equipment installed by Landlord and/or other tenants of the
        Project in the future. Landlord shall use its commercially reasonable
        efforts to ensure that Tenant's equipment will not be unreasonably
        interfered with.

G. EMERGENCY GENERATOR. During the Term or extended Term of this Lease, upon
written approval by Landlord, which shall not be unreasonably withheld, delayed
or conditioned, Tenant shall have the right, at its sole cost, expense and
responsibility, in accordance with all applicable laws and in a location as
determined by Landlord, to install one (1) emergency electrical generator per
Building and all appurtenant equipment. The maintenance and operation of said
equipment shall be at Tenant's sole cost, expense and responsibility and subject
to Paragraph 11 of this Lease.

1.  Driveways, sidewalks, halls, passages, exits, entrances, elevators,
    escalators and stairways shall not be obstructed by tenants or used by
    tenants for any purpose other than for ingress to and egress from their
    respective premises. The driveways, sidewalks, halls, passages, exits,
    entrances, elevators and stairways are not for the use of the general public
    and Landlord shall in all cases retain the right to control and prevent
    access thereto by all persons whose presence, in the judgment of Landlord,
    shall be prejudicial to the safety, character, reputation and interests of
    the Building, the Project and its tenants, provided that nothing herein
    contained shall be construed to prevent such access to persons with whom any
    tenant normally deals in the ordinary course of such tenant's business
    unless such persons are engaged in illegal activities. No tenant, and no
    employees or invitees of any tenant, shall go upon the roof of any Building,
    except as authorized by Landlord.

2.  No sign, placard, banner, picture, name, advertisement or notice, visible
    from the exterior of the Premises or the Building or the common areas of the
    Building shall be inscribed, painted, affixed, installed or otherwise
    displayed by Tenant either on its Premises or any part of the Building or
    Project without the prior written consent of Landlord in Landlord's sole and
    absolute discretion. Landlord shall have the right to remove any such sign,
    placard, banner, picture, name, advertisement, or notice without notice to
    and at the expense of Tenant, which were installed or displayed in violation
    of this rule. If Landlord shall have given such consent to Tenant at any
    time, whether before or after the execution of Tenant's Lease, such consent
    shall in no way operate as a waiver or release of any of the provisions
    hereof or of the Lease, and shall be deemed to relate only to the particular
    sign, placard, banner, picture, name, advertisement or notice so consented
    to by Landlord and shall not be construed as dispensing with the necessity
    of obtaining the specific written consent of Landlord with respect to any
    other such sign, placard, banner, picture, name, advertisement or notice.
    All approved signs or lettering on doors and walls shall be printed,
    painted, affixed or inscribed at the expense of Tenant by a person or vendor

    written consent of Landlord, all such items shall be installed inboard of

    such persons. Landlord and its agents shall not be liable for damages for
    any error concerning the admission to, or exclusion from, the Building or
    the Project of any person. During the continuance of any invasion, mob,
    riot, public excitement or other circumstance rendering such action
    advisable in Landlord's opinion, Landlord reserves the right (but shall not
    be obligated) to prevent access to the Building and the Project during the
    continuance of that event by any means it considers appropriate for the
    safety of tenants and protection of the Building, property in the Building
    and the Project.

6.  Tenant shall not alter any lock or access device or install a new or
    additional lock or access device or bolt on any door of its Premises,

    used for any purpose other than that for which they were constructed and no
    foreign substance of any kind whatsoever shall be thrown into them. The

    business or activity other than that specifically provided for in such
    Tenant's Lease. Tenant shall not accept hairstyling, barbering, shoeshine,

    shall be borne by the tenant by whom, or by whose contractors, employees or
    invitees, the damage shall have been caused.

15. Tenant shall not place a load upon any floor of its Premises which exceeds
    the load per square foot which such floor was designed to carry or which is
    allowed by law. Business machines and mechanical equipment belonging to

    structure of the Building or to any space therein to such a degree as to be
    objectionable to Landlord or to any tenants in the Building shall be placed

                             IMPROVEMENT AGREEMENT

               This Lease Improvement Agreement ("IMPROVEMENT AGREEMENT") sets
forth the terms and conditions relating to construction of the initial tenant
improvements described in the Plans to be prepared and approved as provided
below (the "TENANT IMPROVEMENTS") in the Premises. Capitalized terms used but
not otherwise defined herein shall have the meanings set forth in the Lease (the
"LEASE") to which this Improvement Agreement is attached and forms a part.

1. Base Building Work. The "Base Building Work" will be performed by Landlord at
Landlord's sole cost and expense ACCORDING TO EXHIBIT G OF THIS LEASE.

2. Plans and Specifications.

        A. Landlord and Tenant shall jointly retain the services of Devcon
Construction Incorporated (the "SPACE PLANNER") to prepare a detailed space plan
(the "SPACE PLAN") mutually satisfactory to Landlord and Tenant for the
construction of the Tenant Improvements in the Premises. Landlord and Tenant
shall approve or disapprove the Space Plan and any proposed revisions thereto in
writing within three (3) business days after receipt thereof, which approval
shall not be unreasonably withheld.

        B. Based on the approved Space Plan, Landlord and Tenant shall cause the
Space Planner to prepare detailed plans, specifications and working drawings for
the construction of the Tenant Improvements (the "PLANS"). Landlord and Tenant
shall diligently pursue the preparation of the Plans. Landlord and Tenant shall
approve or disapprove the Plans and any proposed revisions thereto, including
the estimated cost of the Tenant Improvements, in writing within three (3)
business days after receipt thereof. If Landlord or Tenant fails to approve or
disapprove the Space Plan or Plans or any revisions thereto within the time
limits specified herein, Landlord or Tenant shall be deemed to have approved the
same. Landlord and Tenant shall use diligent efforts to cause the final Plans
and the cost estimate to be prepared and approved no later than thirty (30) days
after the execution of the Lease.

        C. Notwithstanding Landlord's preparation, review and approval of the
Space Plan and the Plans and any revisions thereto, Landlord shall have no
responsibility or liability whatsoever for any errors or omissions contained in
the Space Plan or Plans, or to verify dimensions or conditions, or for the
quality, design or compliance with applicable Regulation of any improvements
described therein or constructed in accordance therewith. Landlord hereby
assigns to Tenant all warranties and guarantees by the Space Planner or the
contractor who constructs the Tenant Improvements relating to the Tenant
Improvements, and Tenant hereby waives all claims against Landlord relating to,
or arising out of the design or construction of, the Tenant Improvements.

3. Specifications for Standard Tenant Improvements.

        A. Specifications and quantities of standard building components which
will comprise and be used in the construction of the Tenant Improvements
("STANDARDS") are set forth in SCHEDULE 2 to this EXHIBIT C. As used herein,
"STANDARDS" or "BUILDING STANDARDS" shall mean the standards for a particular
item selected from time to time by Landlord for the Building, including those
set forth on SCHEDULE 2 of this EXHIBIT C, or such other standards of equal or
better quality as may be mutually agreed between Landlord and Tenant in writing.

        B. No deviations from the Standards are permitted without Landlord's
prior written consent which such consent shall not be unreasonably withheld,
delayed or conditioned.

4. Tenant Improvement Cost.

A. The cost of the Tenant Improvements shall be paid for by Tenant, including,
without limitation, the cost of: Standards; space plans and studies;
architectural and engineering fees incurred in connection with preparation of
the Plans; permits, approvals and other governmental fees; labor, material,
equipment and supplies; construction fees and other amounts payable to
contractors or subcontractors; taxes; off-site improvements; remediation and
preparation of the Premises for construction of the Tenant Improvements; taxes;
filing and recording fees; premiums for insurance and bonds; and all other
costs expended or to be expended in the construction of the Tenant Improvements,
including those costs incurred for construction of elements of the Tenant
Improvements in the Premises, which construction was performed by Landlord prior
to the execution of the Lease or for materials comprising the Tenant
Improvements which were purchased by Landlord prior to the execution of the
Lease.

Provided Tenant is not in default under the Lease, including this Improvement
Agreement, Landlord shall contribute a one-time tenant improvement allowance not
to exceed $25.00 per square foot times the rentable area of the Premises,
("TENANT IMPROVEMENT ALLOWANCE"), to be credited by Landlord toward the cost of
the initial Tenant Improvements. If the cost of the Tenant Improvements exceeds
the Tenant Improvement Allowance, Tenant shall pay Landlord such excess cost
within five (5) business days after Landlord's notice to Tenant of such excess
cost. If the cost of the Tenant Improvements is less than the Tenant Improvement
Allowance, Tenant shall receive a credit towards Base Rent as follows: Within
sixty (60) days after Tenant takes possession of the entire Premises, Landlord
shall deliver a statement to Tenant detailing the actual Tenant Improvement
costs spent by Landlord. For every whole $1.00 per square foot of the Tenant
Improvement Allowance that is unspent by Landlord, Tenant shall receive a rent
credit which shall be applied to Rent for the next month of the Term.
Notwithstanding the foregoing, in no event shall said rent credit be greater
than $3.00 per square foot of the rentable area of the Premises.

        C. If the cost of the Tenant Improvements increases after the Tenant's
approval of the Plans due to the requirements of any governmental agency or
applicable Regulation or any other reason, Tenant shall pay Landlord the amount
of such increase above the Tenant Improvement Allowance within five (5) business
days after notice from Landlord of such increase.

        D. If Tenant requests any change(s) in the Plans after approval of the
estimate of the cost of the Tenant Improvements and any such requested changes
are approved by Landlord in writing (which consent shall not be unreasonably
withheld, delayed or conditioned), Landlord shall advise Tenant promptly of any
cost increases and/or delays such approved change(s) will cause in the
construction of the Tenant Improvements. Tenant shall approve or disapprove any
or all such change(s) within three (3) business days after notice from Landlord
of such cost increases and/or delays. To the extent Tenant disapproves any such
cost increase and/or delay attributable thereto, Landlord shall have the right,
in its sole discretion, to disapprove Tenant's request for any changes to the
approved Plans. If the cost of the Tenant Improvements increases due to any
changes in the Plan(s) requested by Tenant, Tenant shall pay Landlord the amount
of such increase within five (5) business days after notice from Landlord of
such increase and Tenant's approval thereof in accordance with this Paragraph
4.D.

in accordance with the construction contract specified herein. Upon Tenant's
approval of the Plans including the estimate of the cost of the Tenant
Improvements and Landlord's receipt of payment of any such estimated cost
exceeding the amount of the Tenant Improvement Allowance, Landlord and Tenant
shall cause Devcon Construction Incorporated to proceed to secure a building
permit and commence construction of the Tenant Improvements provided that
Landlord and Tenant shall cooperate together in executing permit applications

Landlord shall not be liable for any direct or indirect damages suffered by
Tenant as a result of delays in construction beyond Landlord's reasonable
control, including, but not limited to, delays due to strikes or unavailability
of materials or labor, or delays caused by Tenant (including delays by the Space
Planner, the contractor or anyone else performing services on behalf of Landlord
or Tenant).

        C. If any work is to be performed on the Premises solely by Tenant or
Tenant's contractor or agents:

               (1) Such work shall proceed upon Landlord's written approval
(which consent shall not be unreasonably withheld, delayed or conditioned) of
Tenant's contractor, public liability and property damage insurance carried by
Tenant's contractor, and detailed plans and specifications for such work, shall
be at Tenant's sole cost and expense and shall further be subject to the
provisions of Paragraphs 12 and 27 of the Lease.

               (2) All work shall be done in conformity with a valid building
permit when required, a copy of which shall be furnished to Landlord before such
work is commenced, and in any case, all such work shall be performed in
accordance with all applicable Regulations. Notwithstanding any failure by
Landlord to object to any such work, Landlord shall have no responsibility for
Tenant's failure to comply with all applicable Regulations.

               (3) If required by Landlord or any lender of Landlord, all
work by Tenant or Tenant's contractor or agents shall be done with union labor
in accordance with all union labor agreements applicable to the trades being
employed.

               (4) All work by Tenant or Tenant's contractor or agents shall
be scheduled through Landlord.

               (5) Tenant or Tenant's contractor or agents shall arrange for
necessary utility, hoisting and elevator service with Landlord's contractor and
shall pay such reasonable charges for such services as may be charged by
Tenant's or Landlord's contractor.

               (6) Tenant's entry to the Premises for any purpose, including,
without limitation, inspection or performance of Tenant construction by Tenant's
agents, prior to the date Tenant's obligation to pay rent commences shall be
subject to all the terms and conditions of the Lease except the payment of Rent.
Tenant's entry shall mean entry by Tenant, its officers, contractors, licensees,
agents, servants, employees, guests, invitees, or visitors.

               (7) Tenant shall promptly reimburse Landlord upon demand for
any reasonable expense actually incurred by the Landlord by reason of faulty
work done by Tenant or its contractors or by reason of any delays caused by such
work, or by reason of inadequate clean-up.

6. Completion and Rental Commencement Date.

        A. Tenant's obligation to pay Rent under the Lease shall commence on the
applicable date described in Paragraph 2 of the Lease, however:

               (1) If Tenant delays in preparing or approving the Space Plans
or the Plans, or fails to approve the estimate of the cost of the Tenant
Improvements or any other matter requiring Tenant's approval, or to pay the
excess cost of Tenant Improvements, in each case within the time limits
specified herein; or

               (2) If the construction period is extended because Tenant
requests any changes in construction, or modifies the approved Plans or if the
same do not comply with applicable Regulations; or

               (3) If Landlord is otherwise delayed in the construction of
the Tenant Improvements for any act or omission of or breach by Tenant or anyone
performing services on behalf of Tenant or on account of any work performed on
the Premises by Tenant or Tenant's contractors or agents, then the date
described in Paragraph 2 of the Lease shall be deemed to be accelerated by the
total number of days of Tenant delays described in (a) through (c) above (each,
a "TENANT DELAY"), calculated in accordance with the provisions of Paragraph 6.B
below.

        B. If the Term of the Lease has not already commenced pursuant to the
provisions of Paragraph 2 of the Lease and substantial completion of the Tenant
Improvements has been delayed on account of any Tenant Delays, then upon actual
substantial completion of the Tenant Improvements (as defined in Paragraph 2 of
the Lease), Landlord shall notify Tenant in writing of the date substantial
completion of the Tenant Improvements would have occurred but for such Tenant
Delays, and such date shall thereafter be deemed to be the Term Commencement
Date for all purposes under the Lease. Tenant shall pay to Landlord, within )
five (5) business days after receipt of such written notice (which notice shall
include a summary of Tenant Delays), the per diem Base Rent times the number of
days between the date the Term Commencement Date would have otherwise occurred
but for the Tenant Delays (as determined by Landlord's written documentation
describing Tenant Delays), and the date of actual substantial completion of the
Tenant Improvements.

        C. Promptly after substantial completion of the Tenant Improvements,
Landlord shall give notice to Tenant and Tenant shall conduct an inspection of
the Premises with a representative of Landlord and develop with such
representative of Landlord a punchlist of items of the Tenant Improvements that
are not complete or that require corrections. Upon receipt of such punchlist,
Landlord shall proceed diligently to remedy such items at Landlord's cost and
expense provided such items are part of the Tenant Improvements to be
constructed by Landlord hereunder and are otherwise consistent with Landlord's
obligations under this Improvement Agreement and provided Tenant has fully paid
Landlord for the cost of the Tenant Improvements exceeding the Tenant
Improvement Allowance (with any dispute between Landlord and Tenant pertaining
thereto to be resolved by submitting to binding arbitration conducted and
determined in San Diego County according to the prevailing rules of the American
Arbitration Association for arbitration of commercial disputes). Substantial
completion shall not be delayed notwithstanding delivery of any such punchlist.

        D. A default under this Improvement Agreement shall constitute a default
under the Lease, and the parties shall be entitled to all rights and remedies
under the Lease in the event of a default hereunder by the other party
(notwithstanding that the Term thereof has not commenced).

        E. Without limiting the "as-is" provisions of the Lease, except for the
Tenant Improvements, if any, to be constructed by Landlord pursuant to this
Improvement Agreement, Tenant accepts the Premises in its "as-is" condition and
acknowledges that it has had an opportunity to inspect the Premises prior to

                              CONSTRUCTION EXHIBIT

        This Construction Exhibit ("CONSTRUCTION EXHIBIT") sets forth the terms
and conditions relating to construction of the Base Building Work for the
Premises described in the Improvement Plans to be prepared and approved as
provided below. Capitalized terms used but not otherwise defined herein shall
have the meanings set forth in the Lease (the "Lease") to which this
Construction Exhibit is attached and forms a part.

                                   ARTICLE II

                              GENERAL REQUIREMENTS

1.1 PROJECT ARCHITECT AND PROJECT CONTRACTOR:

        Landlord has retained, at its cost and responsibility, Smith Consulting
Architects of San Diego and its consultants (the "PROJECT ARCHITECT") to prepare
the Construction Documents for Landlord's Work (each as defined herein), in
substantial conformance with the schematic design drawings attached as Schedule
1 to this Exhibit G (the "SCHEMATIC DESIGN DRAWINGS"), the specifications for
the Base Building Work (as defined herein) attached as Schedule 2 to this
Exhibit G (the "SPECIFICATIONS"), and the requirements of this Exhibit G. The
general contractor, subcontractors and others required to complete construction
of Landlord's Work (the "PROJECT CONTRACTOR(S)"), selected as described below,
shall construct all Landlord's Work. The Project Contractors shall be selected
through a competitive bidding process. Landlord shall obtain a minimum of three
(3) bids from professionally qualified and licensed general contractors, one of
which shall be Devcon Construction Incorporated, with a base of operations in
San Diego County chosen by Landlord.

1.2 CATEGORIES OF WORK:

        The work to be performed at the Premises, the Building and the Project
is categorized as follows:

        1.2.1 "BASE BUILDING WORK" is all work and improvements shown and
        described on the Improvement Plans (defined below).

        1.2.2 "CONSTRUCTION DOCUMENTS" shall consist of the items listed on
        Schedule 3 attached hereto.

        1.2.3 "IMPROVEMENT PLANS" shall mean collectively the Schematic Design
        Drawings, the Specifications and the Construction Documents.

        1.2.4 "LANDLORD'S WORK" shall mean all of the combined work and
        improvements referenced herein as the Base Building Work. This work is
        to be performed by Landlord at Landlord's sole cost. Landlord shall not
        be responsible to pay for or perform any work or improvements other than
        Landlord's Work. Landlord's Work shall be the sole property of Landlord.

        1.2.5 "TENANT'S WORK" is as described in Article II and includes the
        Tenant Improvements described in Exhibit C to this Lease. This work is
        to be performed by Tenant at Tenant's sole cost, subject to receipt of
        the Tenant Improvement Allowance described therein.

1.3 DEVELOPMENT SCHEDULE:

        The time schedule for completion of the Base Building Work is set forth
in Schedule 4 attached hereto (the "DEVELOPMENT SCHEDULE"). Landlord shall use
its best efforts to cause the Base Building Work to be completed in accordance
with the Development Schedule subject to Force-Majeure Delays as defined in this
Exhibit G.

1.4 CONSTRUCTION DOCUMENTS:

        1.4.1 On or before that date set forth in the Development Schedule (but
subject to delays as specified in Article IV of this Exhibit G), Landlord shall
cause the Project Architect (and to the extent necessary in Landlord's
discretion, the Project Contractor(s)) to prepare the Construction Documents for
the Base Building Work. Such Construction Documents shall be in substantial
conformance with the Schematic Design Drawings and the Specifications for the
Base Building Work.

        1.4.2 The Project Architect shall submit to Landlord a pre-purchase
package with all information necessary to purchase all long-lead items or
equipment necessary to construct Landlord's Work and to meet the Development
Schedule. Any delay in receiving necessary information from Tenant for a
long-lead item of Tenant Equipment (as defined in Section 2.1 below), or delay
in delivery of Tenant Equipment which causes a delay in the Development Schedule
as a consequence, shall be a Tenant-Caused Delay.

1.5 CONFORMANCE OF CONSTRUCTION DOCUMENTS:

        1.5.1 The Schematic Design Drawings and the Specifications for the Base
Building Work attached to this Exhibit G as Schedules 1 and 2 and are approved
by the parties and shall be the basis for the design and construction of the
Base Building Work.

        1.5.2 At or before the time as specified in the Development Schedule,
the Project Architect shall submit the Construction Documents to Landlord and
Tenant to confirm that such plans substantially conform to Schedules 1 and 2.
Landlord and Tenant shall have seven (7) business days from the receipt of such
Construction Documents to notify the other party in writing (i) of the
substantial conformance of the Construction Documents with Schedules 1 and 2, or
(ii) that the party believes certain portions are not in substantial
conformance. Any notice that certain portions are not in substantial conformance
shall specifically state the reason for such non-conformance and describe in
detail the change(s) necessary to bring the Construction Documents into
substantial conformance. Landlord's or Tenant's failure to timely submit such
notice may, at the other party's option, be deemed the first party's final
approval of the Construction Documents; or such other party may submit such
Construction Documents to binding arbitration pursuant to Article VI below, to
determine if the Construction Documents are in substantial conformance with
Schedules 1 and 2. Any delay in Landlord's or Tenant's delivery of such
substantial conformance (or non-conformance) notice and any time necessary for
arbitration pursuant thereto shall be a Landlord- or Tenant-Caused Delay
accordingly.

                                       36
<PAGE>   101

        1.5.3 If pursuant to the notice in Section 1.5.2 above, Landlord and/or
Tenant determine that any portion of the Construction Documents are not in
substantial conformance with Schedules 1 and 2, then Landlord and Tenant shall
meet, within three (3) business days of notice from either party, with the
Project Architect and shall attempt reasonably and in good faith to reach
agreement on the Construction Documents not later than three (3) business days
after the date of delivery of such notice of non-conformance. If, despite their
reasonable good faith efforts, Landlord and Tenant are unable to agree on the
substantial conformance (or non-conformance) of the Construction Documents
within the allotted time period, such dispute and the delay associated therewith
shall be resolved by the Arbitrator pursuant to Article VI of this Exhibit G.

        1.5.4 Tenant and Landlord may be expected to review and acknowledge
conformance or non-conformance of the Construction Documents on an incremental
basis for each of the phases of the Base Building Work in accordance with the
Development Schedule.

        1.5.5 Notwithstanding anything to the contrary, upon satisfaction of the
substantial conformance review pursuant to Sections 1.5.2 and 1.5.3 above, the
substantially conforming Construction Documents or any incremental portions
thereof shall, from that time forward, supersede that same portion of Schedules
1 and 2. Furthermore, Tenant and Landlord acknowledge that changes to the
Construction Documents may be required during the construction process due to
the then existing condition of the Project or due to discrepancies in the
Construction Documents. Tenant hereby consents to such changes to the
Construction Documents; provided such changes do not materially affect the
functionality of the Premises.

1.6 BUILDING PERMIT FOR BASE BUILDING WORK

        1.6.1 Within the time period specified in the Development Schedule (but
subject to delays as specified herein), the Project Architect shall be
responsible for processing from the City of San Diego ("CITY") a building permit
for the construction of the Base Building Work. If the City rejects the
Construction Documents and thereby prevents the issuance of a building permit,
the Project Architect shall make all necessary corrections to the Construction
Documents required by the City. Tenant acknowledges that changes by the City to
the Construction Documents or Landlord's Work in the Premises which is already
completed may be necessary, due to Building Codes and interpretations thereof
("CITY REQUIRED CHANGES"). Tenant hereby consents to such City Required Changes;
provided such changes do not materially affect the functionality of the
Premises.

        1.6.2 Upon the City's approval of the Construction Documents and permit
application, Project Architect shall deliver to Landlord the Base Building Work
building permit(s) and the approved set of Construction Documents marked "For
Construction". Such permit(s) may be phased.

        1.6.3 To obtain the Base Building Work building permit (referenced in
Section 1.6.1 above), Landlord may require special information which can
reasonably only be supplied by Tenant. Tenant shall supply such information
within three (3) business days of receipt of written request from Landlord, or
as soon as possible thereafter,Project Architect or Project Contractors
requesting such information.

        1.7.2 On or before the completion of Landlord's Work, Landlord, the
Project Architect and Tenant shall conduct a walk-through inspection of the
Premises and shall jointly prepare a punch list of minor construction correction
items which need to be corrected. Landlord shall cause Project Contractor to
correct such punch list items as soon as is reasonably feasible within thirty
(30) days thereafter; provided, however, if, by the nature of such correction,
and so long as Tenant's ability to occupy or use the Premises is not materially
effected or delayed, more than thirty (30) days is required to effect such
correction, Landlord shall commence correction as soon as is reasonably feasible
within such thirty (30) day period and shall diligently pursue the correction to
completion.

1.8 INSURANCE DURING CONSTRUCTION:

        1.8.1 From the commencement of Landlord's Work until the completion of
Landlord's Work, Landlord (or the Project Contractor) shall obtain and maintain
property damage, public liability and workers' compensation insurance in amounts
as required by the Lease to insure Landlord and its agents, lender and Tenant
from and against liability for death or injury to persons and for damage to
property during the performance of Landlord's Work. In addition, Landlord (or
the Project Contractor) shall carry builder's risk insurance in an amount to
cover Landlord's Work.

        1.8.2 From the commencement until the completion of Landlord's Work,
Tenant shall obtain and maintain, at Tenant's expense, property damage, public
liability and workers' compensation insurance in amounts specified in Paragraph
8.B. of the Lease, to insure Landlord and its agents, the Project Architect, the
Project Contractor and Tenant from and against liability for death of or injury
to persons and for damage to property caused by or arising from Tenant's access

employees, agents or contractors.

                                   ARTICLE II

                            TENANT'S WORK AND PERMITS

        2.1 "TENANT'S WORK" shall include, without limitation, the Tenant
Improvements, the purchase and/or installation of equipment, machinery,
furniture, trade fixtures, moveable partitions, telephone and information
systems, security system and decorations ("TENANT EQUIPMENT") and any
improvements to the Premises which are not Base Building Work. Tenant agrees, at
its own expense (but subject to receipt of the Tenant Improvement Allowance
pursuant to Exhibit C), to permit and complete those improvements described as
"Tenant's Work" without interference with Landlord's Work and in a timely manner
so as to prevent delays in the Development Schedule. Delays in the Development
Schedule which extend the date of Substantial Completion due to Tenant's Work
shall be a Tenant-Caused Delay. Tenant's Work shall comply with all Regulations.
Tenant and its agents shall comply with all reasonable rules and requirements
set forth by the Project Contractor. All Tenant Equipment with electrical
components shall be approved and rated by Underwriters Laboratories for such
equipment's intended use.

        2.2 Tenant shall maintain insurance pursuant to Paragraph 8.B. of the
Lease, and shall cause its contractors to maintain a minimum $1 Million
liability insurance policy, property damage insurance and workers' compensation
insurance covering Tenant's Work in the Premises and at the Project. Tenant's
contractor shall name Landlord and its agents, the Project Architect and the
Project Contractors as additional insureds. Tenant shall provide Landlord with
evidence of all required insurance.

                                       37
<PAGE>   102

        2.3 Tenant shall contract with the Project Contractor (or with such
other contractor as Tenant may select, subject to Landlord's approval, which
approval will not be unreasonably withheld), for the installation of Tenant's
Work, according to Exhibit C of this Lease.

        2.4 Without limiting the generality of Section 2.1 above, Tenant shall
purchase and/or install, at Tenant's expense, all Tenant Equipment and other
improvements in the Premises required by Tenant in the operation of its
business. Any costs, delays, expenses or damages incurred by Landlord arising
out of or related to the performance of Tenant's Work by Tenant, its contractor,
vendors, subcontractors, employees or other agents shall be paid by Tenant to
Landlord.

        2.5 In the event Tenant or Tenant's contractors enter possession of the
Premises for the purpose of performing Tenant's Work, Tenant agrees to
indemnify, defend and hold Landlord and its agents, the Project Architect and
the Project Contractor harmless from any loss or damage to Tenant's or Tenant's
contractor's property, fixtures, equipment, materials or merchandise, or from
liability for death of or injury to any person, except where such loss or damage
arises from the active negligence or willful misconduct of Landlord, its
employees, agents or contractors.

        2.6 Tenant, with the commercially reasonable cooperation of Landlord,
shall be solely responsible for and shall timely obtain any approvals or permits
required for Tenant's Work and Tenant shall pay all architectural, consulting,
and other fees and costs incurred by Tenant associated therewith. All plan check
and building permit fees required on the permit application, all inspection
fees, utility fees, and water and sewer capacity fees (to the extent that such
fees are applicable to the Tenant Improvements) related to Tenant's Work shall
be paid by Tenant. In the event Tenant is unable to procure or is delayed in
procuring permits and approvals required by governing authorities and the
Development Schedule is delayed as a consequence, such delay shall be a
Tenant-Caused Delay as defined in Article IV herein.

        2.7 If a permit is required to install Tenant's Work, Tenant shall
procure such permit and shall deliver a copy of a completed, signed-off
inspection card to Landlord as soon as possible after completion of Tenant's
Work or Tenant's occupancy of the Premises, whichever comes first.

        2.8 The parties acknowledge that in some circumstances, with proper
coordination, Tenant's Work may begin before Landlord's Work is completed.
Landlord, Tenant, the Project Architect and the Project Contractor shall work
cooperatively to coordinate schedules so that Tenant's Work may begin before
Landlord's Work is completed to the extent reasonable and practical, provided
that Tenant's Work does not unreasonably impede or delay Landlord's Work or make
completion of Landlord's Work in any material respect more expensive or
difficult. Scheduling of Landlord's Work shall always have priority. Any delay
in Landlord's Work caused by the concurrent construction of Tenant's Work shall
be a Tenant-Caused Delay.

                                   ARTICLE III

                                 TENANT CHANGES

        3.1 TENANT CHANGE REQUESTS:

               3.1.1 Any changes requested by Tenant to the Construction
Documents shall be requested and instituted in accordance with the provisions of
this Article III and shall be subject to the written approval of Landlord after
consultation with the Project Architect, which approval shall not be
unreasonably withheld, delayed or conditioned. Landlord shall have no
responsibility to approve or implement a Tenant Change (as defined below) if, in
Landlord's reasonable discretion, such change is not in substantial conformance
with the Schematic Design Drawing and the Specifications. Landlord and Tenant
hereby acknowledge that a Tenant Change which causes a delay in the completion
of Landlord's Work, shall be a Tenant-Caused Delay.

               3.1.2 From time to time after the Construction Documents have
been found to be in substantial conformance with the Schematic Design Drawings
and the Specifications pursuant to this Exhibit G, Tenant may request changes to
the Construction Documents or request changes to Landlord's Work in the Premises
which is already completed ("TENANT CHANGE(S)") by notifying Landlord in writing
of the nature and extent of any such requested Tenant Change. If the nature of
such Tenant Change requires revisions to Construction Documents and such change
is approved pursuant to Section 3.1.1 above, then the Project Architect shall
revise the Construction Documents. Such request must be signed by Tenant's
Representative (as defined below) or Landlord shall not be required to process
such Tenant Change request. Landlord shall, before proceeding with a Tenant
Change, use its reasonable efforts to respond to Tenant as soon as is reasonably
possible with an estimate of (i) the time it will take Landlord to analyze the
requested Tenant Change, and (ii) the architectural and engineering fees and
costs which will be incurred in order to analyze the requested Tenant Change,
and thereafter submit to Tenant in writing, within five (5) business days after
Tenant notifies Landlord of the requested Tenant Change (or such longer period
of time as is reasonably required depending on the extent of the Tenant Change
request), an analysis of the estimated additional costs or savings involved and
the period of time, if any, that the Tenant Change will extend the time for
completion of Landlord's Work, which time extension to Landlord's Work will be a
Tenant-Caused Delay. If Tenant fails to expressly approve or disapprove in
writing Landlord's submission within three (3) business days of receipt thereof,
each day of delay in Tenant's approval or disapproval of Landlord's submission
beyond such three (3) business day period which causes a delay in Substantial
Completion of Landlord's Work, shall be a Tenant-Caused Delay. The time for
completion of Landlord's Work shall be extended one (1) day for each day of
delay caused by analyzing and processing Tenant's request for a Tenant Change
(whether or not Landlord's Work, if any, is approved by Tenant) and such delay
which extends the date of Substantial Completion of Landlord's work shall be
a Tenant-Caused Delay.

               3.1.3 If Tenant approves in writing the cost or savings of the
Tenant Change and the extension in time for completion of Landlord's Work, if
any, Landlord shall cause the approved Tenant Change to be instituted. The time
for completion of Landlord's Work shall be extended one (1) day for each day of
delay caused by instituting the Tenant Change requested by Tenant and such delay
which extends the date of Substantial Completion of Landlord's work shall be a
Tenant-Caused Delay.

               3.1.4 All architectural and engineering fees and costs, all
construction fees and costs, and all other costs reasonably and actually
incurred by Landlord in connection with modifications and revisions to the
Construction Documents and Landlord's Work, net of any savings realized with
respect thereto, which result from Tenant Change requests and/or instituting the
Tenant Changes, shall be paid by Tenant.

               3.1.5 Landlord and Tenant agree that time and strict punctual
performance are of the essence with respect to this Article III and that each
shall use due diligence in performing their respective obligations pursuant to
this Article III.

                                   ARTICLE IV

                          DELAYS AND COMPLETION OF WORK

<PAGE>   103

        4.1 Any capitalized terms used in this Exhibit G shall have the same
meaning as set forth in the Lease to which this Exhibit G is attached. The
following capitalized terms shall have the following meanings:

               4.1.1 "SUBSTANTIAL COMPLETION" and "SUBSTANTIALLY COMPLETE" shall
have the same meaning as defined in Paragraph 2.B. of the Lease;

               4.1.2 "TENANT-CAUSED DELAY(S)" shall mean (i) those delay(s)
caused by the failure of Tenant or Tenant's Representative to act within the
time limits set forth in the Development Schedule and this Exhibit G; and (ii)
delays defined as Tenant-Caused Delay(s) pursuant to this Exhibit G;

               4.1.3 "LANDLORD-CAUSED DELAY(S)" shall mean (i) those delay(s)
caused by the failure of Landlord to act within the time limits set forth in the
Development Schedule and this Exhibit G; and (ii) delays defined as
Landlord-Caused Delay(s) pursuant to this Exhibit G;

               4.1.4 "FORCE-MAJEURE DELAY(S)" shall mean delay(s) in completion
of Landlord's Work beyond Landlord's reasonable control, including, but not
limited to, delays caused by acts of God, war, civil commotion (excluding civil
commotion associated with Tenant's use, such delay shall be a Tenant-Caused
Delay), labor disputes, strikes, earthquake, fire, flood or other casualty,
shortages of labor or material, governmental regulations or restrictions, and
weather conditions. The preceding definition of Force-Majeure Delays only
applies to this Exhibit G and shall have no effect on the Lease.

        4.2 COMPLETION OF WORK:

               4.2.1 Landlord shall use its reasonable efforts to Substantially
Complete the phased improvements on or before the estimated completion dates, or
as the completion dates are extended pursuant to the terms of this Exhibit G or
the Lease. The Scheduled Term Commencement Date (but not the date when Rent
commences) shall be extended one (1) day for each day of delay in Substantial
Completion of the phased Base Building Work resulting from Tenant-Caused Delays.

               4.2.2 Any delay in the Substantial Completion of phased
improvements beyond the Scheduled Term Commencement Date, as such may be
extended pursuant to Section 4.2.1 above, for reasons other than Tenant-Caused
Delays shall result in a delay in when Tenant commences to pay Rent, but said
delays shall not entitle Tenant to recover any damages or losses from Landlord.

               4.2.3 All phases of the Premises shall be occupied by Tenant as
soon as each portion is Substantially Complete.

                                    ARTICLE V

                             TENANT'S REPRESENTATIVE

        5.1 Tenant designates Ernst Calais as Tenant's representative ("TENANT'S
REPRESENTATIVE") in connection with the design and construction of the Base
Building Work and Tenant's Work. Tenant's Representative shall use its best
efforts to participate in all meetings where his/her attendance is requested by
Landlord with the Project Architect, third party contractors and consultants,
and the Project Contractor(s) involved in the design and construction of
Landlord's Work. Any questions requiring information from Tenant during design
and construction of the Base Building Work shall be directed to Tenant's
Representative. Tenant represents and warrants that Tenant's Representative is
duly authorized to represent Tenant and that the decisions of Tenant's
Representative shall be binding on Tenant.

        5.2 During the preparation of the Construction Documents and
construction of Landlord's Work, Landlord, the Project Architect or Project
Contractor(s) may request information or clarification from Tenant's
Representative as to the Construction Documents, Tenant's Work and Tenant
Equipment. If the response to such request for information or clarification
requires revisions to the Construction Documents or Landlord's Work in the
Premises already completed, then the Project Architect shall revise the
Construction Documents as soon as possible. If Tenant's Representative fails to
give an answer to any question or clarification as to choice or to provide
required information within three (3) business days (unless more time is
specifically permitted pursuant to this Exhibit G), Landlord may, at its
election but not obligation, make the decision with one (1) day's written notice
to Tenant, and Landlord shall have no liability for the decision except as
otherwise provided for in this Exhibit G, or Landlord may submit the request for
information to the Arbitrator pursuant to Article VI below for a binding
resolution by the Arbitrator.

                                   ARTICLE VI

                         CONSTRUCTION DISPUTE RESOLUTION

        6.1 If any dispute arises in connection with this Exhibit G, such
dispute shall be resolved in strict accordance with this Article VI. Such
dispute shall be resolved by an arbitrator, which shall be selected pursuant to
Section 6.3 below ("ARBITRATOR"). The Arbitrator will have a minimum of ten (10)
years directly relevant design and construction experience in the design and
construction of comparable office buildings in the San Diego County area (or
having such other qualifications as Landlord's Arbitration Representatives and
Tenant's Arbitration Representatives may mutually approve). The Arbitrator shall
be independent from and disinterested in both Landlord and Tenant. Landlord and
Tenant shall each name two (2) representatives ("LANDLORD'S ARBITRATION
REPRESENTATIVES" and "TENANT'S ARBITRATION REPRESENTATIVES") with authority to
represent the parties before the Arbitrator and bind the respective parties in
matters pursuant to this Article. Neither the Arbitrator nor Landlord's
Arbitration Representatives or Tenant's Arbitration Representatives shall be an
attorney unless Landlord and Tenant consent thereto in writing.

        6.2 All disputes to be determined in accordance with this Article shall
be raised by notice to the other party, which notice shall state with
particularity the nature of the dispute and the demand for relief, making
specific reference by Section number to the provision of this Exhibit G alleged
to give rise to the dispute. Such notice shall also refer to this Article and
shall designate the two persons who are representing the party as that party's
Arbitration Representatives.

        6.3 Landlord's Arbitration Representatives and Tenant's Arbitration
Representatives shall mutually and promptly select an Arbitrator who meets the
qualifications set forth in Section 6.1 above. In the event a selection is not
made within three (3) business days after written demand for resolution is made,
the Arbitrator shall, upon the written request of either party, be appointed by
a majority of the Board of Directors of the Associated General Contractors of
San Diego County within three (3) business days of such request. All proceedings
contemplated by this Article shall take place at the location designated for all
job-site meetings, unless Landlord's Arbitration Representatives and Tenant's
Arbitration Representatives mutually agree to another location. The cost for the
Arbitrator's services shall be paid by the least prevailing party in the dispute
as determined by the Arbitrator.

        6.4 In determining any dispute, the Arbitrator shall apply the pertinent
provisions of this Exhibit G without departure therefrom in any respect. The
Arbitrator shall not have the power to add to, modify or change any of the
provisions of this Exhibit G; but this provision shall not prevent in any
appropriate case the interpretation, construction and determination by the
Arbitrator of the applicable provisions of this Exhibit G to the extent
necessary in applying the same to the matters to be determined by the
Arbitrator. As part of resolving a dispute, the Arbitrator shall determine the
allocation of any costs and the days of delay in completing Landlord's Work

                                       39
<PAGE>   104

which directly result from the dispute being considered by the Arbitrator, if
any. The days of delay shall be designated as either Tenant-Caused Delays,
Landlord-Caused Delays or Force-Majeure Delays or any combination of the three
(3) types of delays, as determined by the Arbitrator.

        6.5 During any proceedings pursuant to this Article, Landlord and Tenant
shall, to the extent possible, continue to perform and discharge all of their
respective obligations under this Exhibit G and the Lease.

        6.6 The Arbitrator shall meet with Landlord's Arbitration
Representatives and Tenant's Arbitration Representatives within two (2) business
days of the Arbitrator being selected. The Arbitrator shall thereafter resolve
the issue in dispute within two (2) business days, unless it is mutually agreed
by the Landlord's Arbitration Representatives and Tenant's Arbitration
Representatives that additional time is necessary to resolve the dispute, but in
no event shall such additional time exceed five (5) business days from the
meeting between Landlord's Arbitration Representatives, Tenant's Arbitration
Representatives and the Arbitrator. Landlord and Tenant agree that time and
strict punctual performance are of the essence with respect to each provision of
this Exhibit G, and that any and all decisions of the Arbitrator as to the
matter in dispute shall be binding upon both Landlord and Tenant.

IN WITNESS WHEREOF, the parties hereto have executed this Lease as of the day
and the year first above written.

                              WORK LETTER AGREEMENT

               This Work Letter Agreement ("WORK LETTER") sets forth the terms
and conditions relating to construction of the initial tenant improvements
described in the Plans to be prepared and approved as provided below (the
"TENANT IMPROVEMENTS") in the Premises. Capitalized terms used but not otherwise
defined herein shall have the meanings set forth in the Sublease (the
"SUBLEASE") to which this Work Letter is attached and forms a part.

1. Base Building Work. The "Base Building Work" described on SCHEDULE 1 to this
EXHIBIT D, IF ANY, has been performed by Landlord at Landlord's sole cost and
expense.

2. Plans and Specifications.

        2.1 Subtenant shall retain the services of Howard Sneed Interior
Architecture (the "SPACE PLANNER") to prepare a detailed space plan (the "SPACE
PLAN") mutually satisfactory to Landlord, Sublandlord and Subtenant for the
construction of the Tenant Improvements in the Premises. Subtenant shall submit
the Space Plan and any proposed revisions thereto to Landlord and Sublandlord
for their approval.

        2.2 Based on the approved Space Plan, Subtenant shall cause the Space
Planner to prepare detailed plans, specifications and working drawings mutually
satisfactory to Landlord, Sublandlord and Subtenant for the construction of the
Tenant Improvements (the "PLANS"). Landlord, Sublandlord and Subtenant shall
diligently pursue the preparation of the Plans. Subtenant shall submit the Plans
and any proposed revisions thereto, until Landlord and Sublandlord ultimately
approve the Space Plan and Plans.

        2.3 Subtenant shall be responsible for ensuring that the Plans are
compatible with the design, construction and equipment of the Building, comply
with applicable Regulations and the Standards (defined below), and contain all
such information as may be required to show locations, types and requirements
for all heat loads, people loads, floor loads, power and plumbing, regular and
special HVAC needs, telephone communications, telephone and electrical outlets,
lighting, light fixtures and related power, and electrical and telephone
switches, B.T.U. calculations, electrical requirements and special receptacle
requirements. The Plans shall also include mechanical, electrical, plumbing,
structural and engineering drawings mutually satisfactory to Landlord,
Sublandlord and Subtenant which shall be prepared by ILA/Zammit. Notwithstanding
Landlord's and Sublandlord's preparation, review and approval of the Space Plan
and the Plans and any revisions thereto, Landlord and Sublandlord shall have no
responsibility or liability whatsoever for any errors or omissions contained in
the Space Plan or Plans or any revisions thereto, or to verify dimensions or
conditions, or for the quality, design or compliance with applicable Regulations
of any improvements described therein or constructed in accordance therewith.
Subtenant hereby waives all claims against Landlord and Sublandlord relating to,
or arising out of the design or construction of, the Tenant Improvements.

        2.4 Landlord and/or Sublandlord may approve or disapprove the Space Plan
or Plans or any proposed revision thereto submitted to Landlord and Sublandlord
in Landlord's and Sublandlord's reasonable discretion, provided that Landlord
and Sublandlord shall not unreasonably withhold such approval and provided that
Landlord and Sublandlord shall not object to the Tenant Improvements to the
Premises proposed by Tenant on the basis of aesthetic considerations.
Notwithstanding the foregoing, Landlord and Sublandlord shall have the right to
condition its approval of the Plans upon Subtenant's agreement and undertaking
to remove any improvements as shown thereon which differ from Building Standard
improvements (the "Designated Items") and which are designated by Landlord
and/or Sublandlord at the time Landlord and/or Sublandlord approve the Space
Plan or Plans for removal upon the expiration or earlier termination of the
Sublease and to restore the Premises to a condition mutually agreed upon by
Landlord, Sublandlord and Subtenant at the time Landlord and/or Sublandlord
approve the Space Plan or Plans. If Landlord reasonably determines that the cost
of removing any of the Designated Items and restoring the Sublease Premises
(collectively, the "Removal Costs") will exceed $117,500, then as a further
condition to Landlord's and Sublandlord's approval of the Designated Items,
Subtenant shall deposit with Sublandlord cash or a letter of credit in the
amount of the Removal Costs to secure Subtenant's satisfaction of such
restoration and removal obligations. Landlord and Sublandlord shall approve or
disapprove any Space Plan, Plans or proposed revisions thereto submitted to
Landlord and Sublandlord for Landlord's and Sublandlord's approval within three
(3) business days after Landlord's and Sublandlord's receipt thereof. If
Landlord or Sublandlord has not approved or disapproved in writing any Space
Plan, Plans, or proposed revisions thereto submitted to Landlord and Sublandlord
within five (5) business days after Landlord's and Sublandlord's receipt
thereof, Landlord and Sublandlord shall be deemed to have approved the same.

3. Specifications for Standard Tenant Improvements.

        3.1 Specifications and quantities of standard building components which
will comprise and be used in the construction of the Tenant Improvements
("STANDARDS") are set forth in SCHEDULE 2 to this EXHIBIT D. As used herein,
"STANDARDS" or "BUILDING STANDARDS" shall mean the standards for a particular
item selected from time to time by Landlord for the Building, including those
set forth on SCHEDULE 2 of this EXHIBIT D, or such other standards of equal or
better quality as may be mutually agreed between Landlord and Subtenant in
writing.

        3.2 No deviations from the Standards are permitted without Landlord's
prior written approval, which will not be unreasonably withheld, conditioned or
delayed.

4. Tenant Improvement Cost.

        4.1 The cost of the Tenant Improvements shall be paid for by Subtenant,
including, without limitation, the cost of: Standards; space plans and studies;
architectural and engineering fees; permits, approvals and other governmental
fees; labor, material, equipment and supplies; construction fees and other
amounts payable to contractors or subcontractors; remediation and preparation of
the Premises for construction of the Tenant Improvements; taxes; filing and
recording fees; premiums for insurance and bonds; attorneys' fees; financing
costs; and all other costs expended or to be expended in the construction of the
Tenant Improvements.

        4.2 Provided Subtenant is not in default under the Sublease, including
this Work Letter, Landlord shall contribute a tenant improvement allowance not
to exceed $1,175,000.00 ("TENANT IMPROVEMENT ALLOWANCE") toward the cost of the
initial Tenant Improvements and shall disburse the Tenant Improvement Allowance
to Subtenant as follows: (a) Twenty Percent (20%) of the Tenant Improvement
Allowance within ten (10) days of execution of the Sublease; (b) Seventy Percent
(70%) of the Tenant Improvement Allowance at Substantial Completion of the
entire Premises; and (c) the remaining balance of Ten Percent (10%) of the
Tenant Improvement Allowance upon submission by Subtenant to Landlord copies of
a certificate of completion executed by the Space Planner and Subtenant's
contractor, and unconditional mechanics' lien releases (which mechanics' lien
releases shall be executed by the subcontractors, labor suppliers and
materialmen in addition to Subtenant's contractor), in each case in form and
substance satisfactory to Landlord, and all appropriate bills and supporting
documentation for the work ordered by Subtenant or its contractor or any
subcontractor.

        4.3 In the event the estimated cost of the design and construction of
the Tenant Improvements exceeds the Tenant Improvement Allowance, Subtenant
shall pay such excess cost to Subtenant's contractor. Notwithstanding the
foregoing Subtenant shall

                                      D-1
<PAGE>   122

complete the tenant improvements for the entire Premises within two (2) years of
the Term Commencement Date of the Sublease. No credit shall be given to
Subtenant if the cost of the Tenant Improvements is less than the Tenant
Improvement Allowance or if Subtenant does not complete the Tenant Improvements
within said two (2) year period.

5. Construction of Tenant Improvements.

        5.1 Subtenant shall cause the contractor to proceed to secure a building
permit and commence construction of the Tenant Improvements.

        5.2 Subtenant shall be responsible for obtaining all governmental
approvals to the full extent necessary for the construction and installation of
the Tenant Improvements and for Subtenant's occupancy of the Premises, in
compliance with all applicable Regulations. Subtenant shall employ Good and
Roberts as the contractor or such other contractor or contractors as shall be
reasonably approved by Landlord in writing to construct the Tenant Improvements
in conformance with the approved Space Plan and Plans. The construction
contracts between Subtenant and the approved contractor shall be subject to
Landlord's prior reasonable approval and shall provide for progress payments.
The contractor(s) shall be duly licensed and Landlord's approval of the
contractor(s) shall be conditioned, among other things, upon the contractor's
reputation for quality of work, timeliness of performance, integrity and
Landlord's prior experience with such contractor.

        5.3 Sublandlord and Landlord shall not be liable for any direct or
indirect damages suffered by Subtenant as a result of delays in construction
beyond Landlord's and Sublandlord's reasonable control, including, but not
limited to, delays due to strikes or unavailability of materials or labor, or
delays caused by Subtenant (including delays by the Space Planner, the
contractor or anyone else performing services on behalf of Landlord or
Subtenant).

        5.4 All work to be performed on the Premises by Subtenant or Subtenant's
contractor or agents shall be subject to the following conditions:

               (a) Such work shall proceed upon Landlord's written approval of
Subtenant's contractor, and public liability and property damage insurance
carried by Subtenant's contractor, and shall further be subject to the
provisions of Paragraphs 12 and 27 of the Master Lease.

               (b) All work shall be done in conformity with a valid building
permit when required, a copy of which shall be furnished to Landlord before such
work is commenced, and in any case, all such work shall be performed in a good
and workmanlike and first-class manner, and in accordance with all applicable
Regulations and the requirements and standards of any insurance underwriting
board, inspection bureau or insurance carrier insuring the Premises pursuant to
the Sublease. Notwithstanding any failure by Landlord to object to any such
work, Landlord shall have no responsibility for Subtenant's failure to comply
with all applicable Regulations. Subtenant shall be responsible for ensuring
that construction and installation of the Tenant Improvements will not affect
the structural integrity of the Building.

               (c) Landlord or Landlord's agents shall have the right to inspect
the construction of the Tenant Improvements by Subtenant during the progress
thereof. If Landlord shall give notice of faulty construction or any other
deviation from the approved Space Plan or Plans, Subtenant shall cause its
contractor to make corrections promptly. However, neither the privilege herein
granted to Landlord to make such inspections, nor the making of such inspections
by Landlord, shall operate as a waiver of any right of Landlord to require good
and workmanlike construction and improvements erected in accordance with the
approved Space Plan or Plans.

               (d) Subtenant's construction of the Tenant Improvements shall
comply with the following: (i) the Tenant Improvements shall be constructed in
strict accordance with the approved Space Plan or Plans; (ii) Subtenant's and
its contractor shall submit schedules of all work relating to the Tenant
Improvements to Landlord for Landlord's approval within two (2) business days
following the selection of the contractor and the approval of the Plans.
Landlord shall within three (3) business days after receipt thereof inform
Subtenant of any changes which are necessary and Subtenant's contractor shall
adhere to such corrected schedule; and (iii) Subtenant shall abide by all rules
made by Landlord with respect to the use of freight, loading dock, and service
elevators, storage of materials, coordination of work with the contractors of
other tenants, and any other matter in connection with this Work Letter,
including, without limitation, the construction of the Tenant Improvements.

               (k) REPRESENTATIVES. The Landlord's representative shall be Ms.

6. Insurance Requirements.

        6.1 All of Subtenant's contractors shall carry worker's compensation
insurance covering all of their respective employees, and shall also carry
public liability insurance, including property damage, all with limits, in form
and with companies as are required to be carried by Subtenant as set forth in
the Sublease.

        6.2 Subtenant shall carry "Builder's All Risk" insurance in an amount
approved by Landlord covering the construction of the Tenant Improvements, and
such other insurance as Landlord may require, it being understood and agreed
that the Tenant Improvements shall be insured by Subtenant pursuant to the
Sublease immediately upon completion thereof. Such insurance shall be in amounts
and shall include such extended coverage endorsements as may be reasonably
required by Landlord including, but not limited to, the requirement that all of
Subtenant's contractors shall carry excess liability and Products and Completed
Operation coverage insurance, each in amounts not less than $500,000 per
incident, $1,000,000 in aggregate, and in form and with companies as are
required to be carried by Subtenant as set forth in the Sublease.

        6.3 Certificates for all insurance carried pursuant to this Work Letter
must comply with the requirements of the Sublease and shall be delivered to
Landlord before the commencement of construction of the Tenant Improvements and
before the contractor's equipment is moved onto the site. In the event the
Tenant Improvements are damaged by any cause during the course of the
construction thereof, Subtenant shall immediately repair the same at Subtenant's
sole cost and expense. Subtenant's contractors shall maintain all of the
foregoing insurance coverage in force until the Tenant Improvements are fully
completed and accepted by Landlord, except for any Product and Completed
Operation Coverage insurance required by Landlord, which is to be maintained for
ten (10) years following completion of the work and acceptance by Landlord and
Subtenant. All policies carried under this Paragraph 6 shall insure Landlord and
Subtenant, as their interests may appear, as well as the contractors. All
insurance maintained by Subtenant's contractors shall preclude subrogation
claims by the insurer against anyone insured thereunder. Such insurance shall
provide that it is primary insurance as respects the owner and that any other
insurance maintained by owner is excess and noncontributing with the insurance
required hereunder.

7. Completion and Rental Commencement Date.

        7.1 Subtenant's obligation to pay Rent under the Sublease shall commence
on the Scheduled Term Commencement Date and the Scheduled Term Commencement Date
shall be the Term Commencement Date notwithstanding anything to the contrary
contained in the Sublease. However, Landlord and Sublandlord Delays (as defined
below) shall extend the Term Commencement Date, but only in the event that
substantial completion of the Tenant Improvements is delayed despite Subtenant's
commercially reasonable efforts to adapt and compensate for such delays. In
addition, no Landlord or Sublandlord Delays shall be deemed to have occurred
unless Subtenant has provided notice, in compliance with the Sublease, to
Landlord and Sublandlord specifying that a delay shall be deemed to have
occurred because of actions, inactions or circumstances specified in the notice
in reasonable detail. If such actions, inactions or circumstances are not cured
by Landlord or Sublandlord within one (1) business day after receipt of such
notice ("COUNT DATE"), and if such actions, inaction or circumstances otherwise
qualify as a Landlord or Sublandlord Delay, then a Landlord or Sublandlord Delay
shall be deemed to have occurred commencing as of the Count Date. The Term
Commencement Date shall be extended by one day for each day from the Count Date
that a Landlord or Sublandlord Delay has occurred, as calculated as provided
above. The term "Landlord or Sublandlord Delays," as such term may be used in
this Work Letter, shall mean any delays in the completion of the Tenant
Improvements which are due to any act or omission of Landlord or Sublandlord,
its agents or contractors. Landlord or Sublandlord Delays shall include, but
shall not be limited to: (i) delays in the giving of authorizations or approvals
by Landlord or Sublandlord, (ii) delays due to the acts or failures to act, of
Landlord or Sublandlord, its agents or contractors, where such acts or failures
to act delay the completion of the Tenant Improvements, provided that Subtenant
acts in a commercially reasonable manner to mitigate any such delay, (iii)
delays due to the interference of Landlord or Sublandlord, its agents or
contractors with the completion of the Tenant Improvements or the failure or
refusal of any party to permit Subtenant, its agents and contractors, access to
and use of the Building or any Building facilities or services, including
elevators and loading docks, which access and use are necessary to complete the
Tenant Improvements, and (iv) delays due to Landlord's or Sublandlord's failure
to allow Subtenant sufficient access to the Building and/or the Premises during
Subtenant's move into the Premises.

        7.2 Within ten (10) days after completion of construction of the Tenant
Improvements, Subtenant shall cause a Notice of Completion to be recorded in the
office of the Recorder of the county in which the Building is located in
accordance with Section 3093 of the Civil Code of the State of California or any
successor statute, and shall furnish a copy thereof to Landlord upon such
recordation. If Subtenant fails to do so, Landlord may execute and file the same
on behalf of Subtenant as Subtenant's agent for such purpose, at Subtenant's
sole cost and expense. At the conclusion of construction, (i) Subtenant shall
cause the Space Planner and the contractor (i) to update the approved working
drawings as necessary to reflect all changes made to the approved working
drawings during the course of construction, (ii) to certify to the best of their
knowledge that the "record-set" of as-built drawings are true and correct, which
certification shall survive the expiration or termination of the Lease, and (c)
to deliver to Landlord two (2) sets of copies of such record set of drawings
within ninety (90) days following issuance of a certificate of occupancy for the
Premises, and (iii) Subtenant shall deliver to Landlord a copy of all
warranties, guarantees, and operating manuals and information relating to the
improvements, equipment, and systems in the Premises.

        7.3 A default under this Work Letter shall constitute a default under
the Sublease, and the parties shall be entitled to all rights and remedies under
the Sublease in the event of a default hereunder by the other party
(notwithstanding that the Term thereof has not commenced).

        7.4 Subject to the provisions of the Sublease, except for the Tenant
Improvements, if any, to be constructed by Landlord pursuant to this Improvement
Agreement, Subtenant accepts the Premises in its "as-is" condition and
acknowledges that it has had an opportunity to inspect the Premises prior to
signing the Sublease.

Notwithstanding the foregoing, the type, quantity, frequency and placement of

forth in Section 3.3, Registered Users of the community directory will have
access to Visitalk.com Services at the then prevailing rates established by

summarize and detail such information in a format that meets both Party's
reasonable mutual satisfaction. MP3.com shall have the right to cause an
