activities described in the Lease or the rules then in effect, then Lessor shall
have the right, without notice, in addition to such other rights and remedies
that it may have to remove or tow away the vehicle involved and charge the cost
to Lessee, which cost shall be immediately payable upon demand by Lessor.

             2.2.2 The monthly parking rate [ TEXT MARKED OUT - ILLEGIBLE ] will

subject to change upon five (5) days prior written notice to Lessee. Monthly
parking fees shall be payable one month in advance prior to the first day of
each calendar month.

         2.3 COMMON AREAS-DEFINITION. The term "Common Areas" is defined as all
areas and facilities outside the Premises and within the exterior boundary line
of the Office Building Project that are provided and designated by the Lessor
from time to time for the general non-exclusive use of Lessor, Lessee and of

conform to the rules and regulations attached hereto as Exhibit B with respect
to the Office Building Project and Common Areas, and to cause its employees,
suppliers, shippers, customers, and invitees to so abide and conform. Lessor or
such other person(s) as Lessor may appoint shall have the exclusive control and

modify, amend and enforce said rules and regulations. Lessor shall not be
responsible to Lessee for the noncompliance with said rules and regulations by
other lessees, their agents, employees and invitees of the Office Building
Project.

         2.5 COMMON AREAS-CHANGES. Lessor shall have the right, in Lessor's sole
discretion, from time to time:

             (a) To make changes to the Building interior and exterior and

         3.1 TERM. The term and Commencement Date of this Lease shall be as
specified in paragraph 1.5 of the Basic Lease Provisions.

         3.2 DELAY IN POSSESSION. Notwithstanding said Commencement Date, if for
any reason Lessor cannot deliver possession of the Premises to Lessee on said
date and subject to paragraph 3.2.2, Lessor shall not be subject to any
liability therefor, nor shall such failure affect the validity of this Lease or
the obligations of Lessee hereunder or extend the term hereof; but, in such
case, Lessee shall not be obligated to pay rent or perform any other obligation
of Lessee under the terms of this Lease, except as may be otherwise provided in
this Lease until possession of the Premises is tendered to Lessee, as
hereinafter defined; provided, however, that if Lessor

                                       1
<PAGE>   2

shall not have delivered possession of the Premises within sixty (60) days
following said Commencement Date, as the same may be extended under the terms of
a Work Letter executed by Lessor and Lessee. Lessee may, at Lessee's option, by
notice in writing to Lessor within ten (10) days thereafter, cancel this Lease,
in which event the parties shall be discharged from all obligations hereunder;
provided, however, that, as to Lessee's obligations, Lessee first reimburses
Lessor for all costs incurred for Non-Standard Improvements and, as to Lessor's
obligations, Lessor shall return any money previously deposited by Lessee (less
any offsets due Lessor for Non-Standard Improvements), and provided further,
that if such written notice by Lessee is not received by Lessor within said ten
(10) day period, Lessee's right to cancel this Lease hereunder shall terminate
and be of no further force or effect.

              3.2.1 POSSESSION TENDERED-DEFINED. Possession of the Premises
shall be deemed tendered to Lessee ("Tender of Possession") when (1) the
improvements to be provided by Lessor under this Lease are substantially
completed, (2) the Building utilities are ready for use in the Premises, (3)
Lessee has reasonable access to the Premises, and (4) ten (10) days shall have
expired following advance written notice to Lessee of the occurrence of the
matters described in (1), (2) and (3), above of this paragraph 3.2.1.

              3.2.2 DELAYS CAUSED BY LESSEE. There shall be no abatement of
rent, and the sixty (60) day period following the Commencement Date before which
Lessee's right to cancel this Lease accrues under paragraph 3.2, shall be deemed
extended to the extent of any delays caused by acts or omissions of Lessee,
Lessee's agents, employees and contractors.

         3.3 EARLY POSSESSION. If Lessee occupies the Premises prior to said
Commencement Date, such occupancy shall be subject to all provisions of this
Lease, such occupancy shall not change the termination date, and Lessee shall
pay rent for such occupancy.

         3.4 UNCERTAIN COMMENCEMENT. In the event commencement of the Lease term
is defined as the completion of the improvements, Lessee and Lessor shall
execute an amendment to this Lease establishing the date of Tender of Possession
(as defined in paragraph 3.2.1) or the actual taking of possession by Lessee,
whichever first occurs, as the Commencement Date.

4. RENT.

         4.1 BASE RENT. Subject to adjustment as hereinafter provided in
paragraph 4.3, and except as may be otherwise expressly provided in this Lease,
Lessee shall pay to Lessor the Base Rent for the Premises set forth in paragraph
1.6 of the Basic Lease Provisions, without offset or deduction. Lessee shall pay
Lessor upon execution hereof the advance Base Rent described in paragraph 1.8 of
the Basic Lease Provisions. Rent for any period during the term hereof which is
for less than one month shall be prorated based upon the actual number of days
of the calendar month involved. Rent shall be payable in lawful money of the
United States to Lessor at the address stated herein or to such other persons or
at such other places as Lessor may designate in writing.

         4.2 OPERATING EXPENSE INCREASE. Lessee shall pay to Lessor during the
term hereof, in addition to the Base Rent, Lessee's Share, as hereinafter
defined, of the amount by which all Operating Expenses, as hereinafter defined,
for each Comparison Year exceeds the amount of all Operating Expenses for the
Base Year, such excess being hereinafter referred to as the "Operating Expense
Increase", in accordance with the following provisions:

             (a) "Lessee's Share" is defined, for purposes of this Lease, as the
percentage set forth in paragraph 1.10 of the Basic Lease Provisions, which
percentage has been determined by dividing the approximate square footage of the
Premises by the total approximate square footage of the rentable space contained
in the Office Building Project. It is understood and agreed that the square
footage figures set forth in the Basic Lease Provisions are approximations which
Lessor and Lessee agree are reasonable and shall not be subject to revision
except in connection with an actual change in the size of the Premises or a
change in the space available for lease in the Office Building Project.

             (b) "Base Year" is defined as the calendar year in which the Lease
term commences.

             (c) "Comparison Year" is defined as each calendar year during the
term of this Lease subsequent to the Base Year; provided, however, Lessee shall
have no obligation to pay a share of the Operating Expense Increase applicable
to the first twelve (12) months of the Lease Term (other than such as are
mandated by a governmental authority, as to which government mandated expenses
Lessee shall pay Lessee's Share, notwithstanding they occur during the first
twelve (12) months). Lessee's Share of the Operating Expense Increase for the
first and last Comparison Years of the Lease Term shall be prorated according to
that portion of such Comparison Year as to which Lessee is responsible for a
share of such increase.

             (d) "Operating Expenses" is defined, for purposes of this Lease, to
include all costs, if any, incurred by Lessor in the exercise of its reasonable
discretion, for:

                 (i) The operation, repair, maintenance, and replacement, in
neat, clean, safe, good order and condition, of the Office Building Project,
including but not limited to, the following:

                     (aa) The Common Areas, including their surfaces, coverings,
decorative items, carpets, drapes and window coverings, and including parking
areas, loading and unloading areas, trash areas, roadways, sidewalks, walkways,
parkways, driveways, landscaped areas, striping, bumpers, irrigation systems,
Common Area lighting facilities, building exteriors and roofs, fences and gates;

                     (bb) All heating, air-conditioning, plumbing, electrical
systems, life safety equipment, telecommunication and other equipment used in
common by, or for the benefit of, lessees or occupants of the Office Building
Project, including elevators and escalators, tenant directories, fire detection
systems including sprinkler system maintenance and repair.

                 (ii) Trash disposal, janitorial and security services;

                 (iii) Any other service to be provided by Lessor that is
elsewhere in this Lease stated to be an "Operating Expense";

                 (iv) The cost of the premiums for the liability and property
insurance policies to be maintained by Lessor under paragraph 8 hereof;

                 (v) The amount of the real property taxes to be paid by Lessor
under paragraph 10.1 hereof;

                 (vi) The cost of water, sewer, gas, electricity, and other
publicly mandated services to the Office Building Project;

                 (vii) Labor, salaries and applicable fringe benefits and costs,
materials, supplies and tools, used in maintaining and/or cleaning the Office
Building Project and accounting and a management fee attributable to the
operation of the Office Building Project.

                 (viii) Replacing and/or adding improvements mandated by any
governmental agency and any repairs or removals necessitated thereby amortized
over its useful life according to Federal income tax regulations or guidelines
for depreciation thereof (including interest on the unamortized balance as is
then reasonable in the judgment of Lessor's accountants).

                 (ix) Replacements of equipment or improvements that have a
useful life for depreciation purposes according to Federal income tax guidelines
of five (5) years or less, as amortized over such life.

             (e) Operating Expenses shall not include the costs of replacements
of equipment or improvements that have a useful life for Federal income tax
purposes in excess of five (5) years unless it is of the type described in
paragraph 4.2(d)(viii), in which case their cost shall be included as above
provided.

             (f) Operating Expenses shall not include any expenses paid by any
lessee directly to third parties, or as to which Lessor is otherwise reimbursed
by any third party, other tenant, or by insurance proceeds.

             (g) Lessee's Share of Operating Expenses Increase shall be payable
by Lessee within ten (10) days after a reasonably detailed statement of actual
expenses is presented to Lessee by Lessor. At Lessor's option, however, an
amount may be estimated by Lessor from time to time in advance of Lessee's Share
of the Operating Expense Increase for any Comparison Year, and the same shall be
payable monthly or quarterly, as Lessor shall designate, during each Comparison
Year of the Lease term, on the same day as the Base Rent is due hereunder. In
the event that Lessee pays Lessor's estimate of Lessee's Share of Operating
Expense Increase as aforesaid, Lessor shall deliver to Lessee within sixty (60)
days after the expiration of each Comparison Year a reasonably detailed
statement showing Lessee's Share of the actual Operating Expense Increase
incurred during such year. If Lessee's payments under this paragraph 4.2(g)
during said Comparison Year exceed Lessee's Share as indicated on said
statement, Lessee shall be entitled to credit the amount of such overpayment
against Lessee's Share of Operating Expense Increase next falling due. If
Lessee's payments under this paragraph during said Comparison Year were less
than Lessee's Share as indicated on said statement, Lessee shall pay to Lessor
the amount of the deficiency within ten (10) days after delivery by Lessor to
Lessee of said statement. Lessor and Lessee shall forthwith adjust between them
by cash payment any balance determined to exist with respect to

                                       2
<PAGE>   3

that portion of the last Comparison Year for which Lessee is responsible as to
Operating Expense Increases, notwithstanding that the Lease term may have
terminated before the end of such Comparison Year.

5. SECURITY DEPOSIT. Lessee shall deposit with Lessor upon execution hereof the
security deposit set forth in paragraph 1.9 of the Basic Lease Provisions as
security for Lessee's faithful performance of Lessee's obligations hereunder. If
Lessee fails to pay rent or other charges due hereunder or otherwise defaults
with respect to any provision of this Lease, Lessor may use, apply or retain all
or any portion of said deposit for the payment of any rent or other charge in
default for the payment of any other sum to which Lessor may become obligated by
reason of Lessee's default, or to compensate Lessor for any loss or damage which
Lessor may suffer thereby. If Lessor so uses or applies all or any portion of
said deposit, Lessee shall within ten (10) days after written demand therefor
deposit cash with Lessor in an amount sufficient to restore said deposit to the
full amount then required of Lessee. If the monthly Base Rent shall, from time
to time, increase during the term of this Lease, Lessee shall, at the time of
such increase, deposit with Lessor additional money as a security deposit so
that the total amount of the security deposit held by Lessor shall at all times
bear the same proportion to the then current Base Rent as the initial security
deposit bears to the initial Base Rent set forth in paragraph 1.6 of the Basic
Lease Provisions. Lessor shall not be required to keep said security deposit
separate from its general accounts. If Lessee performs all of Lessee's
obligations hereunder, said deposit, or so much thereof as has not heretofore
been applied by Lessor, shall be returned, without payment of interest or other
increment for its use, to Lessee (or, at Lessor's option, to the last assignee,
if any, of Lessee's interests hereunder) at the expiration of the term hereof,
and after Lessee has vacated the Premises. No trust relationship is created
herein between Lessor and Lessee with respect to said Security Deposit.

6. USE. CONTINUED ON ADDENDUM (NEW 6.4)

         6.1 USE. The Premises shall be used and occupied only for the purpose
set forth in paragraph 1.4 of the Basic Lease Provisions or any other use which
is reasonably comparable to that use and for no other purpose.

         6.2 COMPLIANCE WITH LAW.

             (a) Lessor warrants to Lessee that the Premises, in the state
existing on the date that the Lease term commences, but without regard to
alterations or improvements made by Lessee or the use for which Lessee will
occupy the Premises, does not violate any covenants or restrictions of record,
or any applicable building code, regulation or ordinance in effect on such Lease
term Commencement Date. In the event it is determined that this warranty has
been violated, then it shall be the obligation of the Lessor, after written
notice from Lessee, to promptly, at Lessor's sole cost and expense, rectify any
such violation.

             (b) Except as provided in paragraph 6.2(a), Lessee shall, at
Lessee's expense, promptly comply with all applicable statutes, ordinances,
rules, regulations, orders, covenants and restrictions of record, and
requirements of any fire insurance underwriters or rating bureaus, now in effect
or which may hereafter come into effect, whether or not they reflect a change in
policy from that now existing, during the term or any part of the term hereof,
relating in any manner to the Premises and the occupation and use by Lessee of
the Premises. Lessee shall conduct its business in a lawful manner and shall not
use or permit the use of the Premises or the Common Areas in any manner that
will tend to create waste or a nuisance or shall tend to disturb other occupants
of the Office Building Project.

         6.3 CONDITION OF PREMISES.

             (a) Lessor shall deliver the Premises to Lessee in a clean
condition on the Lease Commencement Date (unless Lessee is already in
possession) and Lessor warrants to Lessee that the plumbing, lighting, air
conditioning, and heating system in the Premises shall be in good operating
condition. In the event that it is determined that this warranty has been
violated, then it shall be the obligation of Lessor, after receipt of written
notice from Lessee, setting forth with specificity the nature of the violation,
to promptly, at Lessor's sole cost, rectify such violation.

             (b) Except as otherwise provided in this Lease, Lessee hereby
accepts the Premises and the Office Building Project in their condition existing
as of the Lease Commencement Date or the date that Lessee takes possession of
the Premises, whichever is earlier, subject to all applicable zoning, municipal,
county and state laws, ordinances and regulations governing and regulating the
use of the Premises, and any easements, covenants or restrictions of record, and
accepts this Lease subject thereto and to all matters disclosed thereby and by
any exhibits attached hereto. Lessee acknowledges that it has satisfied itself
by its own independent investigation that the Premises are suitable for its
intended use, and that neither Lessor nor Lessor's agent or agents has made any
representation or warranty as to the present or future suitability of the
Premises, Common Areas, or Office Building Project for the conduct of Lessee's
business.

7. MAINTENANCE, REPAIRS, ALTERATIONS AND COMMON AREA SERVICES.

         7.1 LESSOR'S OBLIGATIONS. Lessor shall keep the Office Building
Project, including the Premises, interior and exterior walls, roof, and common
areas, and the equipment whether used exclusively for the Premises or in common
with other premises, in good condition and repair; provided, however, Lessor
shall not be obligated to paint, repair or replace wall coverings, or to repair
or replace any improvements that are not ordinarily a part of the Building or
are above then Building standards. Except as provided in paragraph 9.5, there
shall be no abatement of rent or liability of Lessee on account of any injury or
interference with Lessee's business with respect to any improvements,
alterations or repairs made by Lessor to the Office Building Project or any part
thereof. Lessee expressly waives the benefit of any statute now or hereafter in
effect which would otherwise afford Lessee the right to make repairs at Lessor's
expense or to terminate this Lease because of Lessor's failure to keep the
Premises in good order, condition and repair. SEE ADDENDUM.

         7.2 LESSEE'S OBLIGATIONS.

             (a) Notwithstanding Lessor's obligation to keep the Premises in
good condition and repair, Lessee shall be responsible for payment of the cost
thereof to Lessor as additional rent for that portion of the cost of any
maintenance and repair of the Premises, or any equipment (wherever located) that
serves only Lessee or the Premises, to the extent such cost is attributable to
causes beyond normal wear and tear. Lessee shall be responsible for the cost of
painting, repairing or replacing wall coverings, and to repair or replace any
Premises improvements that are not ordinarily a part of the Building or that are
above then Building standards. Lessor may, at its option, upon reasonable
notice, elect to have Lessee perform any particular, such maintenance or repairs
the cost of which is otherwise Lessee's responsibility hereunder. SEE ADDENDUM.

             (b) On the last day of the term hereof, or on any sooner
termination, Lessee shall surrender the Premises to Lessor in the same condition
as received, ordinary wear and tear excepted, clean and free of debris. Any
damage or deterioration of the Premises shall not be deemed ordinary wear and
tear if the same could have been prevented by good maintenance practices by
Lessee. Lessee shall repair any damage to the Premises occasioned by the
Installation or removal of Lessee's trade fixtures, alterations, furnishings and
equipment. Except as otherwise stated in this Lease, Lessee shall leave the air
lines, power panels, electrical distribution systems, lighting fixtures, air
conditioning, window coverings, wall coverings, carpets, wall paneling, ceilings
and plumbing on the Premises and in good operating condition.

         7.3 ALTERATIONS AND ADDITIONS.

             (a) Lessee shall not, without Lessor's prior written consent make
any alterations, improvements, additions, Utility Installations or repairs in,
on or about the Premises, or the Office Building Project. As used in this
paragraph 7.3 the term "Utility Installation" shall mean carpeting, window and
wall coverings, power panels, electrical distribution systems, lighting
fixtures, air conditioning, plumbing, and telephone and telecommunication wiring
and equipment. At the expiration of the term, Lessor may require the removal of
any or all of said alterations, improvements, additions or Utility
Installations, and the restoration of the Premises and the Office Building
Project to their prior condition, at Lessee's expense. Should Lessor permit
Lessee to make its own alterations, improvements, additions or Utility
Installations, Lessee shall use only such contractor as has been expressly
approved by Lessor, and Lessor may require Lessee to provide Lessor, at Lessee's
sole cost and expense, a lien and completion bond in an amount equal to one and
one-half times the estimated cost of such improvements, to insure Lessor against
any liability for mechanic's and materialmen's liens and to insure completion of
the work. Should Lessee make any alterations, improvements, additions or Utility
Installations without the prior approval of Lessor, or use a contractor not
expressly approved by Lessor, Lessor may, at any time during the term of this
Lease, require that Lessee remove any part or all of the same.

                                       3
<PAGE>   4

             (b) Any alterations, improvements, additions or Utility
Installations in or about the Premises or the Office Building Project that
Lessee shall desire to make shall be presented to Lessor in written form, with
proposed detailed plans. If Lessor shall give its consent to Lessee's making
such alteration, improvement, additional or Utility Installation, the consent
shall be deemed conditioned upon Lessee acquiring a permit to do so from its
applicable governmental agencies, furnishing a copy thereof to Lessor prior to
the commencement of the work, and compliance by Lessee with all conditions of
said permit in a prompt and expeditious manner.

             (c) Lessee shall pay, when due, all claims for labor or materials
furnished or alleged to have been furnished to or for Lessee at or for use of
the Premises, which claims are or may be secured by any mechanic's or
materialmen's lien against the Premises, the Building or the Office Building
Project, or any interest therein.

             (d) Lessee shall give Lessor not less than ten (10) days' notice
prior to the commencement of any work in the Premises by Lessee, and Lessee
shall have the right to post notices of non-responsibility in or on the Premises
or the Building as provided by law. If Lessee shall, in good faith, contest the
validity of any such lien, claim or demand, then Lessee shall, at its sole
expense defend itself and Lessor against the same and shall pay and satisfy any
such adverse judgment that may be rendered thereon before the enforcement
thereof against the Lessor or the Premises, the Building or the Office Building
Project, upon the condition that if Lessor shall require, Lessee shall furnish
to Lessor a surety bond satisfactory to Lessor in an amount equal to such
contested lien, claim or demand indemnifying Lessor against liability for the
same and holding the Premises, the Building and the Office Building Project free
from the effect of such lien or claim. In addition, Lessor may require Lessee to
pay Lessor's reasonable attorney's fees and costs in participating in such
action if Lessor shall decide it is to Lessor's best interest so to do.

             (e) All alterations, improvements, additions and Utility
Installations (whether or not such Utility Installations constitute trade
fixtures of Lessee) which may be made to the Premises by Lessee, including but
not limited to, floor coverings, panelings, doors, drapes, built-ins, moldings,
sound attenuation, and lighting and telephone or communication systems, conduit,
wiring and outlets, shall be made and done in a good and workmanlike manner and
of good and sufficient quality and materials and shall be the property of Lessor
and remain upon and be surrendered with the Premises at the expiration of the
Lease term, unless Lessor requires their removal pursuant to paragraph 7.3(a).
Provided Lessee is not in default, notwithstanding the provisions of this
paragraph 7.3(e), Lessee's personal property and equipment, other than that
which is affixed to the Premises so that it cannot be removed without material
damage to the Premises or the Building, and other than Utility Installations,
shall remain the property of Lessee and may be removed by Lessee subject to the
provisions of paragraph 7.2.

             (f) Lessee shall provide Lessor with as-built plans and
specifications for any alterations, improvements, additions or Utility
Installations.

       7.4 UTILITY ADDITIONS. Lessor reserves the right to install new or
additional utility facilities throughout the Office Building Project for the
benefit of Lessor or Lessee, or any other lessee of the Office Building Project,
including, but not by way of limitation, such utilities as plumbing, electrical
system, communication systems, and fire protection and detection systems, so
long as such installations do not unreasonably interfere with Lessee's use of
the Premises.

8. INSURANCE; INDEMNITY.

       8.1 LIABILITY INSURANCE-LESSEE. Lessee shall, at Lessee's expense, obtain
and keep in force during the term of this Lease a policy of Comprehensive
General Liability insurance utilizing an Insurance Services Office standard form
with Board Form General Liability Endorsement (GL040) or equivalent, in an
amount of not less than $1,000,000 per occurrence of bodily injury and property
damage combined or in a greater amount as reasonably determined by Lessor and
shall insure Lessee with Lessor as an additional insured against liability
arising out of the use, occupancy or maintenance of the Premises. Compliance
with the above requirement shall not, however, limit the liability of Lessee
hereunder.

       8.2 LIABILITY INSURANCE-LESSOR. Lessor shall obtain and keep in force
during the term of this Lease a policy of Combined Single Limit Bodily Injury
and Broad Form Property Damage Insurance, plus coverage against such other risks
Lessor deems advisable from time to time, insuring Lessor but not Lessee,
against liability arising out of the ownership, use, occupancy or maintenance of
the Office Building Project in an amount not less than $5,000,000.00 per
occurrence.

       8.3 PROPERTY INSURANCE-LESSEE. Lessee shall, at Lessee's expense, obtain
and keep in force during the term of this Lease for the benefit of Lessee's,
replacement cost fire and extended coverage insurance, with vandalism and
malicious mischief, sprinkler leakage and earthquake sprinkler leakage
endorsements, in an amount sufficient to cover not less than 100% of the full
replacement cost, as the same may exist from time to time, of all of Lessee's
personal property, fixtures, equipment and tenant improvements.

       8.4 PROPERTY INSURANCE-LESSOR. Lessor shall obtain and keep in force
during the term of this Lease a policy or policies of insurance covering loss or
damage to the Office Building Project improvements, but not Lessee's personal
property, fixtures, equipment or tenant improvements, in the amount of the full
replacement cost thereof, as the same may exist from time to time, utilizing
Insurance Services Office standard form, or equivalent, providing protection
against all perils included within the classification of fire, extended
coverage, vandalism, malicious mischief, plate glass, and such other perils as
Lessor deems advisable or may be required by a lender having a lien on the
Office Building Project. In addition, Lessor shall obtain and keep in force,
during the term of this Lease, a policy of rental value insurance covering a
period of one year, with loss payable to Lessor, which insurance shall also
cover all Operating Expenses for said period. Lessee will not be named in any
such policies carried by Lessor and shall have no right to any proceeds
therefrom. The policies required by these paragraphs 8.2 and 8.4 shall contain
such deductibles as Lessor or the aforesaid lender may determine. In the event
that the Premises shall suffer an insured loss as defined in paragraph 9.1(f)
hereof, the deductible amounts under the applicable insurance policies shall be
deemed an Operating Expense. Lessee shall not do or permit to be done anything
which shall invalidate the insurance policies carried by Lessor. Lessee shall
pay the entirety of any increase in the property insurance premium for the
Office Building Project over what it was immediately prior to the commencement
of the term of this Lease if the increase is specified by Lessor's insurance
carrier as being caused by the nature of Lessee's occupancy or any act or
omission of Lessee.

       8.5 INSURANCE POLICIES. Lessee shall deliver to Lessor copies of
liability insurance policies required under paragraph 8.1 or certificates
evidencing the existence and amounts of such insurance within seven (7) days
after the Commencement Date of this Lease. No such policy shall be cancelable or
subject to reduction of coverage or other modification except after thirty (30)
days prior written notice to Lessor. Lessee shall, at least thirty (30) days
prior to the expiration of such policies, furnish Lessor with renewals thereof.

       8.6 WAIVER OF SUBROGATION. Lessee and Lessor each hereby release and
relieve the other, and waive their entire right of recovery against the other
for direct or consequential loss or damage arising out of or incident to the
perils covered by property insurance carried by such party, whether due to the
negligence of Lessor or Lessee or their agents, employees, contractors and/or
invitees. If necessary all property insurance policies required under this Lease
shall be endorsed to so provide.

       8.7 INDEMNITY. Lessee shall indemnify and hold harmless Lessor and its
agents, Lessor's master or ground lessor, partners and lenders, from and against
any and all claims for damage to the person or property of anyone or any entity
arising from Lessee's use of the Office Building Project, or from the conduct of
Lessee's business or from any activity, work or things done, permitted or
suffered by Lessee in or about the Premises or elsewhere and shall further
indemnify and hold harmless Lessor from and against any and all claims, costs
and expenses arising from any breach of default in the performance of any
obligation on Lessee's part to be performed under the terms of this Lease, or
arising from any act or omission of Lessee, or any of Lessee's agents,
contractors, employees, or invitees, and from and against all costs, attorney's
fees, expenses and liabilities incurred by Lessor as the result of any such use,
conduct, activity, work, things done, permitted or suffered, breach, default or
negligence, and in dealing reasonably therewith, including but not limited to
the defense or pursuit of any claim or any action or proceeding involved
therein; and in case any action or proceeding be brought against Lessor by
reason of any such matter, Lessee upon notice from Lessor shall defend the same
at Lessee's expense by counsel reasonably satisfactory to Lessor and Lessor
shall cooperate with Lessee in such defense. Lessor need not have first paid any
such claim in order to be so indemnified. Lessee, as a material part of the
consideration to Lessor, hereby assumes all risk of damage to properly of Lessee
or injury to persons, in, upon or about the Office Building Project arising from
any cause and Lessee hereby waives all claims in respect thereof against Lessor.

       8.8 EXEMPTION OF LESSOR FROM LIABILITY. Lessee hereby agrees that Lessor
shall not be liable for injury to Lessee's business or any loss of income
therefrom or for loss of or damage to the goods, wares, merchandise or other
property of Lessee, Lessee's employees, invitees, customers, or any other person
in or about the Premises or the Office Building Project, nor shall Lessor be
liable for injury to the person of Lessee, Lessee's employees, agents or
contractors, whether such damage or injury is caused by or results from theft,
fire, steam, electricity, gas, water or rain, or from the breakage, leakage,
obstruction or other defects of pipes, sprinklers, wires, appliances, plumbing,
air conditioning or lighting fixtures, or from any other cause, whether said
damage or injury results from conditions arising upon the Premises or upon other
portions of the Office Building Project, or from other sources or places, or
from new construction or the repair, alteration or improvement of any part of
the Office Building Project, or of the equipment, fixtures or appurtenances
applicable thereto, and regardless of whether the cause of such damage or injury
or the means of repairing the

any act or neglect of any other lessee, occupant or user of the Office Building
Project, nor from the failure of Lessor to enforce the provisions of any other
lease of any other lessee of the Office Building Project.

damage.

             (b) Notwithstanding paragraph 9.4(a), in the event that Lessee has
an option to extend or renew this Lease, and the time within which said option

operation of law assign, transfer, mortgage, sublet, or otherwise transfer or
encumber all or any part of Lessee's interest in the Lease or in the Premises,
without Lessor's prior written consent, which Lessor shall not unreasonably
withhold Lessor shall respond to Lessee's request for consent hereunder in a
timely manner and any attempted assignment, transfer, mortgage, encumbrance or
subletting without such consent shall be void, and shall constitute a material

paragraph 13.1. "Transfer" within the meaning of this paragraph 12 shall include
the transfer or transfers aggregating: (a) if Lessee is a corporation, more than
twenty-five percent (25%) of the voting stock of such corporation, or (b) if

loss participation in such partnership.

         12.2 LESSEE AFFILIATE. Notwithstanding the provisions of paragraph 12.1
hereof, Lessee may assign or sublet the Premises, or any portion thereof,
without Lessor" consent, to any corporation which controls, is controlled by or
is under common control with Lessee, or to any corporation resulting from the
merger or consolidation with Lessee, or to any person or entity which acquires
all the assets of Lessee as a going concern of the business that is being
conducted on the Premises, all of which are referred to as "Lessee Affiliate",
provided that before such assignment shall be effective, (a) said assignee shall
assume, in full, the obligations of Lessee under this Lease and (b) Lessor shall
be given written notice of such assignment and assumption. Any such assignment
shall not, in any way, affect or limit the liability of Lessee under the terms
of this Lease event if after such assignment or subletting the terms of this
Lease are materially changed or altered without the consent of Lessee, the
consent of whom shall not be necessary.

         12.3 TERMS AND CONDITIONS APPLICABLE TO ASSIGNMENT AND SUBLETTING.

             (a) Regardless of Lessor's consent, no assignment or subletting
shall release Lessee of Lessee's obligations hereunder or alter the primary
liability of Lessee to pay the rent and other sums due Lessor hereunder
including Lessee's Share of Operating Expense Increase, and to perform all other
obligations to be performed by Lessee hereunder.

             (b) Lessor may accept rent from any person other than Lessee
pending approval or disapproval of such assignment.

             (c) Neither a delay in the approval or disapproval of such
assignment or subletting, nor the acceptance of rent, shall constitute a waiver
or estoppel of Lessor's right to exercise its remedies for the breach of any of
the terms or conditions of this paragraph 12 or this Lease.

             (d) If Lessee's obligations under this Lease have been guaranteed
by third parties, then an assignment or sublease, and Lessor's consent thereto,
shall not be effective unless said guarantor's give their written consent to
such sublease and the terms thereof.

             (e) The consent by Lessor to any assignment or subletting shall not
constitute a consent to any subsequent assignment or subletting by Lessee or to
any subsequent or successive assignment or subletting by the sublessee. However,
Lessor may consent to subsequent sublettings and assignments of the sublease or
any amendments or modifications thereto without notifying Lessee or anyone else
liable on the Lease or sublease and without obtaining their consent and such
action shall not relieve such persons from liability under this Lease or said
sublease; however, such persons shall not be responsible to the extent any such
amendment or modification enlarges or increases the obligations of the Lessee or
sublessee under this Lease or such sublease.

             (f) In the event of any default under this Lease, Lessor may
proceed directly against Lessee, any guarantors or any one else responsible for
the performance of this Lease, including the sublessee, without first exhausting
Lessor's remedies against any other person or entity responsible therefore to
Lessor, or any security held by Lessor or Lessee.

             (g) Lessor's written consent to any assignment or subletting of the
Premises by Lessee shall not constitute an acknowledgement that no default then
exists under this Lease of the obligations to be performed by Lessee nor shall
such consent be deemed a waiver of any then existing default, except as may be
otherwise stated by Lessor at the time.

             (h) The discovery of the fact that any financial statement relied
upon by Lessor in giving its consent to an assignment or subletting was
materially false shall, at Lessor's election, render Lessor's said consent null
and void.

         12.4 ADDITIONAL TERMS AND CONDITIONS APPLICABLE TO SUBLETTING.
Regardless of Lessor's consent, the following terms and conditions shall apply
to any subletting by Lessee of all or any part of the Premises and shall be
deemed included in all subleases under this Lease whether or not expressly
incorporated therein.

                                       6
<PAGE>   7

             (a) Lessee hereby assigns and transfers to Lessor all of Lessee's
interest in all rentals and income arising from any sublease heretofore or
hereafter made by Lessee, and Lessor may collect such rent and income and apply
same toward Lessee's obligations under this Lease; provided, however, that until
a default shall occur in the performance of Lessee's obligations under this
Lease, Lessee may receive, collect and enjoy the rents accruing under such
sublease. Lessor shall not, by reason of this or any other assignment of such
sublease to Lessor not by reason of the collection of the rents from a
sublessee, be deemed liable to the sublessee for any failure of Lessee to
perform and comply with any of Lessee's obligations to such sublessee under such
sublease. Lessee hereby irrevocably authorizes and directs any such sublessee,
upon receipt of a written notice from Lessor stating that a default exists in
the performance of Lessee's obligations under this Lease, to pay to Lessor the
rents due and to become due under the sublease. Lessee agrees that such
sublessee shall have the right to rely upon any such statement and request from
Lessor, and that such sublessee shall pay such rents to Lessor without any
obligation or right to inquire as to whether such default exists and
notwithstanding any notice from or claim from Lessee to the contrary. Lessee
shall have no right or claim against said sublessee or Lessor for any such rents
so paid by said sublessee to Lessor.

             (b) No sublease entered into by Lessee shall be effective unless
and until it has been approved in writing by Lessor. In entering into any
sublease, Lessee shall use only such form of sublessee as is satisfactory to
Lessor, and once approved by Lessor, such sublease shall not be changed or
modified without Lessor's prior written consent. Any sublease shall, by reason
of entering into a sublease under this Lease, be deemed, for the benefit of
Lessor, to have assumed and agreed to conform and comply with each and every
obligation herein to be performed by Lessee other than such obligations as are
contrary to or inconsistent with provisions contained in a sublease to which
Lessor has expressly consented in writing.

             (c) In the event Lessee shall default in the performance of its
obligations under this Lease, Lessor at its option and without any obligation to
do so, may require any sublessee to attorn to Lessor, in which event Lessor
shall undertake the obligations of Lessee under such sublease from the time of
the exercise of said option to the termination of such sublease; provided,
however, Lessor shall not be liable for any prepaid rents or security deposit
paid by such sublessee to Lessee or for any other prior defaults or Lessee under
such sublease.

             (d) No sublessee shall further assign or sublet all or any part of
the Premises without Lessor's prior written consent.

             (e) With respect to any subletting to which Lessor has consented,
Lessor agrees to deliver a copy of any notice of default by Lessee to the
sublessee. Such sublessee shall have the right to cure a default of Lessee
within three (3) days after service of said notice of default upon such
sublessee, and the sublessee shall have a right of reimbursement and offset from
and against Lessee for any such defaults cured by the sublessee, lessee, and the
sublessee shall have a right of reimbursement and offset from and against Lessee
for any such defaults cured by the sublessee,

         12.5 LESSOR'S EXPENSES. In the event Lessee shall assign or sublet the
Premises or request the consent of Lessor to any assignment or subletting or if
Lessee shall request the consent of Lessor for any act Lessee proposes to do
then Lessee shall pay Lessor's reasonable costs and expense incurred in
connection therewith, including attorneys', architects', engineers', or other
consultants' fees.

         12.6 CONDITIONS TO CONSENT. Lessor reserves the right to condition any
approval to assign or sublet upon Lessor's determination that (a) the proposed
assignee or sublessee shall conduct a business on the Premises of a quality
substantially equal to that of Lessee and consistent with the general character
of the other occupants of the Office Building Project and not in violation of
any exclusives or rights then held by other tenants, and (b) the proposed
assignee or sublessee be at least as financially responsible as Lessee was
expected to be at the time of the execution of this Lease or of such assignment
or subletting, whichever is greater. Continued on Addendum. SEE ADDENDUM (NEW
12.7)

13. DEFAULT; REMEDIES.

         13.1 DEFAULT. The occurrence of any one or more of the following events
shall constitute a material default of this Lease by Lessee:

             (a) The vacation or abandonment of the Premises by Lessee. Vacation
of the Premises shall include the failure to occupy the Premises for continuous
period of sixty (60) days or more, whether or not the rent is paid.

             (b) The breach by Lessee of any of the covenants, conditions or
provisions of paragraph 7.3(a), (b) or (d) (alterations), 12.1 (assignment or
subletting), 13.1(a) (vacation or abandonment), 13.1(e) (insolvency), 13.1(f)
(false statement), 16(a) (estoppel certificate), 30(b) (subordination), 33
(auctions), or 41.1 (easements), all of which are hereby deemed to be material,
non-curable defaults without the necessity of any notice by Lessor to Lessee
thereof.

             (c) The failure by Lessee to make any payment of rent or any other
payment required to be made by Lessee hereunder, as and when due where such
failure shall continue for a period of three (3) days after written notice
thereof from Lessor to Lessee. In the event that Lessor serves Lessee with a
Notice to Pay Rent or Quit pursuant to applicable Unlawful Detainer statutes
such Notice to Pay Rent or Quit shall also constitute the notice required by
this subparagraph. **CONTINUED ON ADDENDUM.

             (d) The failure by lessee to observe or perform any of the
covenants, conditions or provisions of this lease to be observed or performed by
Lessee other than those referenced in subparagraphs (b) and (c), above, where
such failure shall continue for a period of thirty (30) days after written
notice thereof from Lessor to Lessee; provided, however, that if the nature of
Lessee's noncompliance is such that more than thirty (30) days are reasonably
required for its cure, then Lessee shall not be deemed to be in default if
Lessee commenced such cure within said thirty (30) day period and thereafter
diligently pursues such cure to completion. To the extent permitted by law, such
thirty (30) day notice shall constitute the sole and exclusive notice required
to be given to Lessee under applicable Unlawful Detainer statutes.

             (e) (i) The making by Lessee of any general assignment for the
benefit of creditors; (ii) Lessee becoming a "debtor" as defined in 11 U.S.C.
ss. 101 or any successor statute thereto (unless, in the case of a petition
filed against Lessee, the same is dismissed within sixty (60) days; (iii) the
appointment of a trustee or receiver to take possession of substantially all of
Lessee's assets located at the Premises or of Lessee's interest in this Lease,
where possession is not restored to Lessee within thirty (30) days; or (iv) the
attachment, execution or other judicial seizure of substantially all of Lessee's
assets located at the Premises or of Lessee's interest in this Lease, where such
seizure is not discharged within thirty (30) days. In the event that any
provision of this paragraph 13.1(e) is contrary to any applicable law, such
provision shall be of no force or effect.

             (f) The discovery by Lessor that any financial statement given to
Lessor by Lessee, or its successor in interest or by any guarantor of Lessee's
obligation hereunder, was materially false.

         13.2 REMEDIES. In the event of any material default or breach of this
Lease by Lessee, Lessor may at any time thereafter, with or without notice or
demand and without limiting Lessor in the exercise of any right or remedy which
Lessor may have by reason of such default:

             (a) Terminate Lessee's right to possession of the Premises by any
lawful means, in which case this Lease and the term hereof shall terminate and
Lessee shall immediately surrender possession of the Premises to Lessor. In such
event Lessor shall be entitled to recover from Lessee all damages incurred by
Lessor by reason of Lessee's default including, but not limited to, the cost of
recovering possession of the Premises; expenses of reletting, including
necessary renovation and alteration of the Premises, reasonable attorneys' fees,
and any real estate commission actually paid; the worth at the time of award by
the court having jurisdiction thereof of the amount by which the unpaid rent for
the balance of the term after the time of such award exceeds the amount of such
rental loss for the same period that Lessee proves could be reasonably avoided;
that portion of the leasing commission paid by Lessor pursuant to paragraph 15
applicable to the unexpired term of this Lease.

             (b) Maintain Lessee's right to possession in which case this Lease
shall continue in effect whether or not Lessee shall have vacated or abandoned
the Premises. In such event Lessor shall be entitled to enforce all of Lessor's
rights and remedies under this Lease, including the right to recover the rent as
it becomes due hereunder.

             (c) Pursue any other remedy now or hereafter available to Lessor
under the laws or judicial decisions of the state wherein the Premises are
located. Unpaid installments of rent and other unpaid monetary obligations of
Lessee under the terms of this Lease shall bear interest from the date due at
the maximum rate then allowable by law.

         13.3 DEFAULT BY LESSOR. Lessor shall not be in default unless Lessor
fails to perform obligations required of Lessor within a reasonable time, but in
no event later than thirty (30) days after written notice by Lessee to Lessor
and to the holder of any first mortgage or deed of trust covering the Premises
whose name and address shall have theretofore been furnished to Lessee in
writing, specifying wherein Lessor has failed to perform such obligation;
provided, however, that if the nature of Lessor's obligation is such that more
than thirty (30) days are required for performance then Lessor shall not be in
default if Lessor commences performance within such 30-day period and thereafter
diligently pursues the same to completion.

         13.4 LATE CHARGES. Lessee hereby acknowledges that late payment by
Lessee to Lessor of Base Rent, Lessee's Share of Operating Expense Increase or
other sums due hereunder will cause Lessor to incur costs not contemplated by
this Lease, the exact amount of which will be extremely difficult to ascertain.
Such costs include, but are not limited to, processing and accounting charges,
and late charges which may be imposed on Lessor by the terms of any mortgage or
trust deed covering the Office Building Project. Accordingly, if any installment
of Base Rent, Operating Expense Increase, or any other sum due from Lessee shall
not be received by Lessor or Lessor's designee within ten (10) days after such
amount shall be due, then, without any requirement for notice to Lessee, Lessee
shall pay to Lessor a late charge equal to 6% of such overdue amount. The
parties hereby agree that such late charge represents a fair and reasonable
estimate of the costs Lessor will incur by reason of late payment by Lessee.
Acceptance of such late charge by Lessor shall in no event constitute a waiver
of Lessee's default with respect to such overdue amount, nor prevent Lessor from
exercising any of the other rights and remedies granted hereunder.

14. CONDEMNATION. If the Premises or any portion thereof or the Office Building
Project are taken under the power of eminent domain, or sold under the threat of
the exercise of said power (all of which are herein called "condemnation"), this
Lease shall terminate as to the part so taken as of the date the condemning
authority takes title or possession, whichever first occurs; provided that if so
much of the Premises or the Office Building Project are taken by such
condemnation as would substantially and adversely affect the operation and
profitability of Lessee's business conducted from the Premises, Lessee shall
have the option, to be exercised only in writing within thirty (30) days after
Lessor shall have given Lessee written notice of such taking (or in the absence
of such notice, within thirty (30) days after the condemning authority shall
have taken possession), to terminate this Lease as of the date the condemning
authority takes such possession. If Lessee does not terminate this Lease in
accordance with the foregoing, this Lease shall remain in full force and effect
as to the portion of the Premises remaining, except that the rent and Lessee's
Share of Operating Expense Increase shall be reduced in the proportion that the
floor area of the Premises taken bears to the total floor area of the Premises.
Common Areas taken shall be excluded from the Common Areas usable by Lessee and
no reduction of rent shall occur with respect thereto or by reason thereof.
Lessor shall have the option in its sole discretion to terminate this Lease as
of the taking of possession by the condemning authority, by giving written
notice to Lessee of such election within thirty (30) days after receipt of
notice of a taking by condemnation of any part of the Premises or the Office
Building Project. Any award for the taking of all or any part of the Premises or
the Office Building Project under the power of eminent domain or any payment
made under threat of the exercise of such power shall be the property of Lessor,
whether such award shall be made as compensation for diminution in value of the
leasehold or for the taking of the fee, or as severance damages; provided,
however, that Lessee shall be entitled to any separate award for loss of or
damage to Lessee's trade fixtures, removable personal property and unamortized
tenant improvements that have been paid for by Lessee. For that purpose the cost
of such improvements shall be amortized over the original term of this Lease
excluding any options. In the event that this Lease is not terminated by reason
of such condemnation, Lessor shall to the extent of severance damages received
by Lessor in connection with such condemnation, repair any damage to the
Premises caused by such condemnation except to the extent that Lessee has been
reimbursed therefor by the condemning authority. Lessee shall pay any amount in
excess of such severance damages required to complete such repair.

15. BROKER'S FEE. [DELETED] FEES SUBJECT TO A SEPARATE AGREEMENT OUTSIDE OF THIS
LEASE.

16. ESTOPPEL CERTIFICATE.

less than ten (10) days' prior written notice from the other party ("requesting
party") execute, acknowledge and deliver to the requesting party a statement in
writing (i) certifying that this Lease is unmodified and in full force and
effect (or, if modified, stating the nature of such modification and certifying
that this Lease, as so modified, is in full force and effect) and the date to
which the rent and other charges are paid in advance, if any, and (ii)
acknowledging that there are not, to the responding party's knowledge, any
uncured defaults on the part of the requesting party, or specifying such
defaults if any are claimed. Any such statement may be conclusively relied upon
by any prospective purchaser or encumbrancer of the Office Building Project or
of the business of Lessee.

             (b) At the requesting party's option, the failure to deliver such
statement within such time shall be a material default of this Lease by the
party who is to respond, without any further notice to such party, or it shall
be conclusive upon such party that (i) this Lease is in full force and effect,
without modification except as may be represented by the requesting party, (ii)
there are no uncured defaults in the requesting party's performance, and (iii)
if Lessor is the requesting party, not more than one month's rent has been paid
in advance.

             (c) Lessor desires to finance, refinance, or sell the Office
Building Project, or any part thereof, Lessee hereby agrees to deliver to any
lender or purchaser designated by Lessor such financial statements of Lessee as
may be reasonably required by such lender or purchaser. Such statements shall
include the past three (3) years' financial statements of Lessee. All such
financial statements shall be received by Lessor and such lender or purchaser in
confidence and shall be used only for the purposes herein set forth.

17. LESSOR'S LIABILITY. The term "Lessor" as used herein shall mean only the
owner or owners, at the time in question, of the fee title or a lessee's
interest in a ground lease of the Office Building Project, and except as
expressly provided in paragraph 15, in the event of any transfer of such title
of interest, Lessor herein named (and in case of any subsequent transfers then
the grantor) shall be relieved from and after the date of such transfer of all
liability as respects Lessor's obligations thereafter to be performed, provided
that any funds in the hands of Lessor or the then grantor at the time of such
transfer, in which Lessee has an interest, shall be delivered to the grantee.
The obligations contained in this Lease to be performed by Lessor shall, subject
as aforesaid, be binding on Lessor's successors and assigns, only during their
respective periods of ownership.

18. SEVERABILITY. The invalidity of any provision of this Lease as determined by
a court of competent jurisdiction shall be in no way affect the validity of any
other provision hereof.

19. INTEREST ON PAST-DUE OBLIGATIONS. Except as expressly herein provided, any
amount due to Lessor not paid when due shall bear interest at the maximum rate
then allowable by law or judgments from the date due. Payment of such interest
shall not excuse or cure any default by Lessee under this Lease; provided,
however, that interest shall not be payable on late charged incurred by Lessee
nor on any amounts upon which late charges are paid by Lessee.

20. TIME OF ESSENCE. Time is of the essence with respect to the obligations to
be performed under this Lease.

21. ADDITIONAL RENT. All monetary obligations of Lessee to Lessor under the
terms of this Lease, including but not limited to Lessee's Share of Operating
Expense Increase and any other expense payable by Lessee hereunder shall be
deemed to be rent.

22. INCORPORATION OF PRIOR AGREEMENTS; AMENDMENTS. This Lease contains all
agreements of the parties with respect to any matter mentioned herein. No prior
or contemporaneous agreement or understanding pertaining to any such matter
shall be effective. This Lease may be modified in writing only, signed by the
parties in interest at the time of the modification. Except as otherwise stated
in this Lease, Lessee hereby acknowledges that neither the real estate broker
listed in paragraph 15 hereof nor any cooperating broker on this transaction nor
the Lessor or any employee or agents of any of said persons has made any oral or
written warranties or representations to Lessee relative to the condition or use
by Lessee of the Premises or the Office Building Project and Lessee acknowledges
that Lessee assumes all responsibility regarding the Occupational Safety Health
Act, the legal use and adaptability of the Premises and the compliance thereof
with all applicable laws and regulations in effect during the term of this
Lease.

23. NOTICES. Any notice required or permitted to be given hereunder shall be in
writing and may be given by personal delivery or by certified or registered
mail, and shall be deemed sufficiently given if delivered or addressed to Lessee
or to Lessor at the address noted below or adjacent to the signature of the
respective parties, as the case may be. Mailed notices shall be deemed given
upon actual receipt at the address required, or forty-eight hours following
deposit in the mail, postage prepaid, whichever first occurs. Either party may
by notice to the other specify a different address for notice purposes except
that upon Lessee's taking possession of the Premises, the Premises shall
constitute Lessee's address for notice purposes. A copy of all notice required
or permitted to be given to Lessor hereunder shall be concurrently transmitted
to such party or parties at such addresses as Lessor may from time to time
hereafter designate by notice to Lessee.

24. WAIVERS. No waiver by Lessor of any provision hereof shall be deemed a
waiver of any other provision hereof or of any subsequent breach by Lessee of
the same or any other provision. Lessor's consent to, or approval of, any act
shall not be deemed to render unnecessary the obtaining of Lessor's consent to
or approval of any subsequent act by Lessee. The acceptance of rent hereunder by
Lessor shall not be a waiver of any preceding breach by Lessee of any provision
hereof, other than the failure of Lessee to pay the particular rent so accepted,
regardless of Lessor's knowledge of such preceding breach at the time of
acceptance of such rent.

25. RECORDING. Either Lessor or Lessee shall, upon request of the other,
execute, acknowledge and deliver to the other a "short form" memorandum of this
Lease for recording purposes.

26. HOLDING OVER. If Lessee, with Lessor's consent, remains in possession of the
Premises or any part thereof after the expiration of the term hereof, such
occupancy shall be a tenancy from month to month upon all the provisions of this
Lease pertaining to the obligations of Lessee, except that the rent payable
shall be two hundred percent (200%) of the rent payable immediately preceding
the termination date of this Lease, and all Options, if any, granted under the
terms of this Lease shall be deemed terminated and be of no further effect
during said month to month tenancy.

27. CUMULATIVE REMEDIES. No remedy or election hereunder shall be deemed
exclusive but shall, wherever possible, be cumulative with all other remedies at
law or in equity.

28. COVENANTS AND CONDITIONS. Each condition of this Lease performable by Lessee
shall be deemed both a covenant and a condition.

29. BINDING EFFECT; CHOICE OF LAW. Subject to any provisions hereof restricting
assignment or subletting by Lessee and subject to the provisions of paragraph
17, this Lease shall bind the parties, their personal representatives,
successors and assigns. This Lease shall be governed by the laws of the State
where the Office Building Project is located and any litigation concerning this
Lease between the parties hereto shall e initiated in the county in which the
Office Building Project is located.

30. SUBORDINATION.

             (a) This Lease, and any Option or right of first refusal granted
hereby, at Lessor's option, shall be subordinate to any ground lease, mortgage,
deed of trust, or any other hypothecation or security now or hereafter placed
upon the Office Building Project and to any and all advances made on the
security thereof and to all renewals, modifications, consolidations,
replacements and extensions thereof. Notwithstanding such subordination,
Lessee's right to quiet possession of the Premises shall not be disturbed if
Lessee is not in default and so long as Lessee shall pay the rent and observe
and perform all of the provisions of this Lease, unless this Lease is otherwise
terminated pursuant to its terms. If any mortgagee, trustee or ground lessor
shall elect to have this Lease and any Options granted hereby prior to the lien
of its mortgage, deed of trust or ground lease, and shall give written notice
thereof to Lessee, this Lease and such Options shall be deemed prior to such
mortgage, deed of trust or ground lease, whether this Lease or such Options are
dated prior or subsequent to the date of said mortgage, deed of trust or ground
lease or the date of recording thereof.

             (b) Lessee agrees to execute any documents required to effectuate
an attornment, a subordination, or to make this Lease or any Option granted
herein prior to the lien of any mortgage, deed of trust or ground lease, as the
case may be. Lessee's failure to execute such documents within ten (10) days
after written demand shall constitute a material default by Lessee hereunder
without further notice to Lessee or, at Lessor's option, Lessor shall execute
such documents on behalf of Lessee as Lessee's attorney-in-fact. Lessee does
hereby make, constitute and irrevocably appoint Lessor as Lessee's
attorney-in-fact and in Lessee's name, place and stead, to execute such
documents in accordance with this paragraph 30(b).

31. ATTORNEYS' FEES.

or a separate suit, and whether or not such action is pursued to decision of
judgment. The provisions of this paragraph shall inure to the benefit of the
broker named herein who seeks to enforce a right hereunder.

fees reasonably incurred in good faith.

         31.3 Lessor shall be entitled to reasonable attorneys' fees and all
other costs and expenses incurred in the preparation and service of notice of
default and consultations in connection therewith, whether or not a legal
transaction is subsequently commenced in connection with such default.

32. LESSOR'S ACCESS.

other necessary structures, making such alterations, repairs, improvements or
additions to the Premises or to the Office Building Project as Lessor may
reasonably deem necessary or desirable and the erecting, using and maintaining

premises as long as there is no material adverse effect to Lessee's use of the
Premises. Lessor may at any time place on or about the Premises or the Building
any ordinary "For Sale" signs and Lessor may at any time during the last 120
days of the term hereof place on or about the Premises any ordinary "For Sale"
signs.

         32.2 All activities of Lessor pursuant to this paragraph shall be
without abatement of rent, nor shall Lessor have any liability to Lessee for the
same.

         32.3 Lessor shall have the right to retain keys to the Premises and to
unlock all doors in or upon the Premises other than to files, vaults and sales,
and in the case of emergency to enter the Premises by any reasonably appropriate
means, and any such entry shall not be deemed a forcible or unlawful entry or
detainer of the Premises or an eviction. Lessee waives any charges for damages
or injuries or interference with Lessee's property or business in connection
therewith.

33. AUCTIONS. Lessee shall not conduct, nor permit to be conducted, either
voluntarily or involuntarily, any auction upon the premises or the Common Areas
without first having obtained Lessor's prior written consent. Notwithstanding
anything to the contrary in this Lease, Lessor shall not be obligated to
exercise any standard of reasonableness in determining whether to grant such
consent. The holding of any auction on the Premises or Common Areas in violation
of this paragraph shall constitute a material default of this Lease.

34. SIGNS. Lessee shall not place any sign upon the Premises or the Office
Building Project without Lessor's prior written consent. Under no circumstances
shall Lessee place a sign on any roof of the Office Building Project. (CONTINUED
ON ADDENDUM)

mutual cancellation thereof, or a termination by Lessor, shall not work a merger
and shall at the option of Lessor, terminate all or any existing subtenancies or
may, at the option of Lessor, operate as an assignment to Lessor of any or all
of such subtenancies.

36. CONSENTS. Except for paragraphs 33 (auctions) and 34 (signs) hereof,
wherever in this Lease the consent of one party is required to an act of the
other party such consent shall not be unreasonably withheld or delayed.

37. GUARANTOR. In the event that there is a guarantor of this Lease, said
guarantor shall have the same obligations as Lessee under this Lease.

and performing all of the covenants, conditions and provisions on Lessee's part
to be observed and performed hereunder, Lessee shall have quiet possession of
the Premises for the entire term hereof subject to all of the provisions of this
Lease. The individuals executing this Lease on behalf of Lessor represent and
warrant to Lessee that they are fully authorized and legally capable of
executing this Lease on behalf of Lessor and that such execution is binding upon
all parties holding an ownership interest in the Office Building Project.

employees, for overnight parking of vehicles without Landlord's written

particular Parking Spaces for use by persons selected by Landlord provided that
Tenant's rights under the Lease are preserved. Landlord will not be liable to

or LIMITED TIME PARKING (or similar designation).

26. If the Parking Areas are damaged or destroyed, or if the use of the Parking
Areas are limited or prohibited by any governmental authority, or the use or
operation of the Parking Areas is limited or prevented by strikes or other labor
difficulties or other causes beyond Landlord's control, Tenant's inability to
use the Parking Spaces will not subject Landlord to any liability to Tenant and
will not relieve Tenant of any of it of its obligations under the Lease and the
Lease will remain in full force and effect. Tenant will pay to Landlord upon
demand, and Tenant indemnifies Landlord against, any and all loss or damage to
the Parking Areas, or any equipment, fixtures, or signs used in connection with

any of its employees, agents, invitees, or visitors.

omitted to be done by Landlord or Landlord's agent during the term of the Lease

an eviction by Landlord of any Tenant nor will it be deemed an acceptance of
surrender of the Premises by any Tenant, and no agreement to accept such
termination or surrender will be valid unless in writing signed by Landlord. The
delivery of keys to any employee or agent of Landlord will not constitute a
termination of the Lease or a surrender of the Premises unless such delivery of
keys is done in connection with a written instrument executed by Landlord
approving the termination or surrender.

modify or amend, in whole or in part, the terms, agreements and conditions of

risk.
