leases from Lessor, the Premises, for the term, at the rental, and upon all of
the terms, covenants and conditions set forth in this Lease. Unless otherwise
provided herein, any statement of size set forth in this Lease, or that may have

        2.2     CONDITION.

                (a)  Lessee is currently occupying the Premises under a Lease
between Lessor and Lessee which expires on April 30, 2000.

$250,000 (the "Tenant Improvement Allowance") for upgrades to the Premises to be
performed prior to or promptly following the Commencement Date pursuant to

Lessee's expense. Said plans, specifications, and cost estimates shall be
subject to review and approval by Lessor and by an architect designated by
Lessor, as a tenant improvement project cost. The upgrade work shall be
performed by one or more licensed contractor(s) approved by Lessor pursuant to
construction contract(s) approved by Lessor. Lessor's Tenant Improvement
Allowance shall be disbursed for payment of current improvement costs incurred
prior to or promptly following commencement of this Lease term, after approval
by the parties of final plans and specifications and costs and the execution or
construction contract(s) for the work. Lessor's Tenant Improvement Allowance

<PAGE>   3
monthly installments pursuant to the construction contract(s) as the upgrade
work is performed or upon completion of the upgrade work as provided in the
construction contract(s).  The structural repair to the wall panel in which an
exterior entrance was installed by a tenant shall be performed promptly
following the Commencement Date.  The cost thereof shall be charged to Lessor's
Tenant Improvement Allowance.

                (c)  The cost of all approved tenant improvement work in excess
of Lessor's Tenant Improvement Allowance (including, but not limited to, the
cost of any alterations to the Premises required in order to comply with the
Americans With Disabilities Act ("ADA") which exceeds the Tenant Improvement
Allowance), and any additional approved tenant improvement work which Lessee
elects to perform, shall be performed at Lessee's expense. Any unspent portion
of the Tenant Improvement Allowance will be retained by Lessor.

                (d)  Except for the tenant improvement work referred to in
Paragraph 2.2(b) and (c) above, Lessee shall accept the Premises in their "as
is" condition as of the Commencement Date.

        2.3     COMPLIANCE.

                (a)  Costs relating to capital expenditures necessitated by
Lessee's specific use of the Premises shall be paid by Lessee. Costs relating to
other capital expenditures, other than those referred to in Paragraphs 7.1(a)
and 7.2, such as costs incurred to comply with non-voluntary, new governmentally
mandated seismic structural modifications) shall initially be paid by Lessor,
and Lessee shall pay to Lessor each month during the remainder of the term of
this Lease, on the date on which Base Rent is due, an amount equal to the
product of multiplying the cost of such item by a fraction, the numerator of
which is one and the denominator of which is the number of months of the useful
life of such item as such useful life is specified pursuant to Federal income
tax regulations or guidelines for depreciation thereof (including interest on
the unamortized balance as is then commercially reasonable in the judgment of
Lessor's accountants).

               (b) Notwithstanding the above, the provisions concerning Capital
Expenditures are intended to apply only to non-voluntary, unexpected, and new
Applicable Requirements. If the Capital Expenditures are instead triggered by
Lessee as a result of an actual or proposed change in use, change in intensity
of use, or modification to the Premises then, and in that event, Lessee shall be
fully responsible for the cost thereof.

        2.4     ACKNOWLEDGEMENTS. Lessee acknowledges that: (a) it has been
advised by Lessor and/or Brokers to satisfy itself with respect to the condition
of the Premises (including but not limited to the electrical, HVAC and fire
sprinkler systems, security, environmental aspects, and compliance with
Applicable Requirements), and their suitability for Lessee's intended use; (b)
Lessee has made such investigation as it deems necessary with reference to such
matters and assumes all responsibility therefor as the same relate to its
occupancy of the Premises; and (c) neither Lessor, Lessor's agents, nor any
Broker has made any oral or written representations or warranties with respect
to said matters other than as set forth in this Lease.

3.      TERM.

        3.1     TERM. The Commencement Date, Expiration Date and Original Term
of this Lease are as specified in Paragraph 1.3.

        3.4     LESSEE COMPLIANCE. Lessor shall not be required to tender
possession of the Premises to Lessee until Lessee complies with its obligation
to provide evidence of insurance (Paragraph 8.5). Pending delivery of such
evidence, Lessee shall be required to perform all of its obligations under this
Lease from and after the Start Date, including the payment of Rent,
notwithstanding Lessor's election to withhold possession pending receipt of such
evidence of insurance. Further, if Lessee is required to perform any other
conditions prior to or concurrent with the Start Date, the Start Date shall
occur but Lessor may elect to withhold possession until such conditions are
satisfied.

4.      RENT.

        4.1.    RENT DEFINED. All monetary obligations of Lessee to Lessor under
the terms of this Lease (except for the Security Deposit) are deemed to be rent
("RENT").

        4.2     PAYMENT. Lessee shall cause payment of Rent to be received by
Lessor in lawful money of the United States, without offset or deduction (except
as specifically permitted in this Lease), on or before the day on which it is
due. Rent for any period during the term hereof which is for less than one (1)
full calendar month shall be prorated based upon the actual number of days of
said month. Payment of Rent shall be made to Lessor at its address stated herein
or to such other persons or place as Lessor may from time to time designate in
writing. Acceptance of a payment which is less than the amount then due shall
not be a waiver of Lessor's rights to the balance of such Rent, regardless of
Lessor's endorsement of any check so stating.

5.      SECURITY DEPOSIT. Lessee shall deposit with Lessor upon execution hereof
the Security Deposit as security for Lessee's faithful performance of its
obligations under this Lease. If Lessee fails to pay Rent, or otherwise Defaults
under this Lease, and Lessee fails to cure such Default following written
notice to Lessee and prior to the expiration of any applicable grace period.

                                  Page 4 of 23
<PAGE>   5
provided for in this Lease, Lessor may use, apply or retain all or any portion
of said Security Deposit for the payment of any amount due Lessor or to
reimburse or compensate Lessor for any liability, expense, loss or damage which
Lessor may suffer or incur by reason thereof. If Lessor uses or applies all or
any portion of said Security Deposit, Lessee shall within ten (10) days after
written request therefor deposit monies with Lessor sufficient to restore said
Security Deposit to the full amount required by this Lease. Lessor shall not be
required to keep the Security Deposit separate from its general accounts. Within
fourteen (14) days after the expiration or termination of this Lease, if Lessor
elects to apply the Security Deposit only to unpaid Rent, and otherwise within
thirty (30) days after the Premises have been vacated pursuant to Paragraph
7.4(c) below, Lessor shall return that portion of the Security Deposit not used
or applied by Lessor. No part of the Security Deposit shall be considered to be
held in trust, to bear interest or to be prepayment for any monies to be paid by
Lessee under this Lease.

6.      USE.

        6.1     USE. Lessee shall use and occupy the Premises only for the
Agreed Use, or any other legal use which is reasonably comparable thereto, and
for no other purpose. Lessee shall not use or permit the use of the Premises in
a manner that is unlawful, creates damage, waste or a nuisance, or that disturbs
owners and/or occupants of, or causes damage to neighboring properties. Lessor
shall not unreasonably withhold or delay its consent to any written request for
a modification of the Agreed Use, so long as the same will not impair the
structural integrity of the improvements on the Premises or the mechanical or
electrical systems therein, is not significantly more burdensome to the
Premises. If Lessor elects to withhold consent, Lessor shall within five (5)
business days after such request give written notification of same, which notice
shall include an explanation of Lessor's objections to the change in use.

        6.2     HAZARDOUS SUBSTANCES.

                (a) REPORTABLE USES REQUIRE CONSENT. The term "HAZARDOUS
SUBSTANCE" as used in this Lease shall mean any product, substance, or waste
whose presence, use, manufacture, disposal, transportation, or release, either
by itself or in combination with other materials expected to be on the Premises,
is either: (i) potentially injurious to the public health, safety or welfare,
the environment or the Premises, (ii) regulated or monitored by any governmental
authority, or (iii) a basis for potential liability of Lessor to any
governmental agency or third party under any applicable statute or common law
theory. Hazardous Substances shall include, but not be limited to, hydrocarbons,
petroleum, gasoline, and/or crude oil or any products, by-products or fractions
thereof. Lessee shall not engage in any activity in or on the Premises which
constitutes a Reportable Use of Hazardous Substances without the express prior
written consent of Lessor and timely compliance (at Lessee's expense) with all
Applicable Requirements. "Reportable Use" shall mean (i) the installation or use
of any above or below ground storage tank, (ii) the generation, possession,
storage, use, transportation, or disposal of a Hazardous Substance that requires
a permit from, or with respect to which a report, notice, registration or
business plan is required to be filed with, any governmental authority, and/or
(iii) the presence at the Premises of a Hazardous Substance with respect to
which any Applicable Requirements requires that a notice be given to persons
entering or occupying the Premises or neighboring properties. Notwithstanding
the foregoing, Lessee may use any ordinary and customary materials reasonably
required to be used in the normal course of the Agreed Use, so long as such use
is in compliance with all Applicable Requirements, is not a Reportable Use, and
does not expose the Premises or neighboring property to any meaningful risk of
contamination or damage or expose Lessor to any liability therefor. In addition,
Lessor may condition its consent to any Reportable Use upon receiving such
additional assurances as Lessor reasonably deems necessary to protect itself,
the public, the Premises and/or the environment against damage, contamination,
injury and/or liability, including, but not limited to, the installation (and
removal on or before Lease expiration or termination) of protective
modifications (such as concrete encasements) and/or increasing the Security
Deposit.

               (b) DUTY TO INFORM. If either Lessor or Lessee knows, or has
reasonable cause to believe, that a Hazardous Substance has come to be located
in, on, under or about the Premises, other than as previously consented to by
Lessor, such party shall immediately give written notice of such fact to the
other party, and provide the other party with a copy of any report, notice,
claim or other documentation which it has concerning the presence of such
Hazardous Substance.

               (c) LESSEE REMEDIATION. Lessee shall not cause or permit any
Hazardous Substance to be spilled or released in, on, under, or about the
Premises (including through the plumbing or sanitary sewer system) and shall
promptly, at Lessee's expense, take all investigatory and/or remedial action
reasonably recommended, whether or not formally ordered or required, for the
cleanup of any contamination of, and for the maintenance, security and/or
monitoring of the Premises or neighboring properties, that was caused or
materially contributed to by Lessee, or pertaining to or involving any Hazardous
Substance brought onto the Premises during the term of this Lease, by or for
Lessee, or any third party.

               (d) LESSEE INDEMNIFICATION. Lessee shall indemnify, defend and
hold Lessor, its agents, employees, lenders and ground lessor, if any, harmless
from and against any and all loss of rents and/or damages, liabilities,
judgments, claims, expenses, penalties, and attorneys' and consultants' fees
arising out of or involving any Hazardous Substance brought onto the Premises by
or for Lessee, or any third party (provided, however, that Lessee shall have no
liability under this Lease with respect to underground migration of any
Hazardous Substance under the Premises from adjacent properties). Lessee's
obligations shall include, but not be limited to, the effects of any
contamination or injury to person, property or the environment created or
suffered by Lessee, and the cost of investigation, removal, remediation,
restoration and/or abatement, and shall survive the expiration or termination of
this Lease. NO TERMINATION, CANCELLATION OR RELEASE AGREEMENT ENTERED INTO BY
LESSOR AND LESSEE SHALL RELEASE LESSEE FROM ITS OBLIGATIONS UNDER THIS LEASE
WITH RESPECT TO HAZARDOUS SUBSTANCES, UNLESS SPECIFICALLY SO AGREED BY LESSOR IN
WRITING AT THE TIME OF SUCH AGREEMENT.

               (e) LESSOR INDEMNIFICATION. Lessor and its successors and assigns
shall indemnify, defend, reimburse and hold Lessee, its employees and lenders,
harmless from and against any and all environmental damages, including the cost
of remediation, which existed as a result of Hazardous Substances on the
Premises prior to the Start Date or which are caused by the gross negligence or
willful misconduct of Lessor, its agents or employees. Lessor's obligations, as
and when required by the Applicable Requirements, shall include, but not be
limited to, the cost of investigation, removal, remediation, restoration and/or
abatement, and shall survive the expiration or termination of this Lease.

<PAGE>   6
               (f) INVESTIGATIONS AND REMEDIATIONS. Lessor shall retain the
responsibility and pay for any investigations or remediation measures required
by governmental entities having jurisdiction with respect to the existence of
Hazardous Substances on the Premises prior to the occupancy of the Premises by
Lessee under the Sublease between Quickturn Design Systems, Inc. and Lessee,
unless such remediation measure is required as a result of Lessee's use
(including "Alterations", as defined in Paragraph 7.3(a) below) of the Premises,
in which event Lessee shall be responsible for such payment. Lessee shall
cooperate fully in any such activities at the request of Lessor, including
allowing Lessor and Lessor's agents to have reasonable access to the Premises at
reasonable times after reasonable prior notice to Lessee (except that prior
notice shall not be required in case of emergency) in order to carry out
Lessor's investigative and remedial responsibilities. At Lessee's election,
Lessor and Lessor's agents shall be accompanied by a representative of Lessee.

               (g) LESSOR TERMINATION OPTION. If a Hazardous Substance Condition
occurs during the term of this Lease, unless Lessee is legally responsible
therefor (in which case Lessee shall make the investigation and remediation
thereof required by the Applicable Requirements and this Lease shall continue in
full force and effect, but subject to Lessor's rights under Paragraph 6.2(d) and
Paragraph 13), Lessor may, at Lessor's option, either (i) investigate and
remediate such Hazardous Substance Condition, if required, as soon as reasonably
possible at Lessor's expense, in which event this Lease shall continue in full
force and effect, or (ii) if the estimated cost to remediate such condition
exceeds twelve (12) times the then monthly Base Rent or $100,000, whichever is
greater, give written notice to Lessee, within thirty (30) days after receipt by
Lessor of knowledge of the occurrence of such Hazardous Substance Condition, of
Lessor's desire to terminate this Lease as of the date sixty (60) days following
the date of such notice. In the event Lessor elects to give a termination
notice, Lessee may, within ten (10) days thereafter, give written notice to
Lessor of Lessee's commitment to pay the amount by which the cost of the
remediation of such Hazardous Substance Condition exceeds an amount equal to
twelve (12) times the then monthly Base Rent or $100,000, whichever is greater.
Lessee shall provide Lessor with said funds or satisfactory assurance thereof
within thirty (30) days following such commitment. In such event, this Lease
shall continue in full force and effect, and Lessor shall proceed to make such
remediation as soon as reasonably possible after the required funds are
available. If Lessee does not give such notice and provide the required funds or
assurance thereof within the time provided, this Lease shall terminate as of the
date specified in Lessor's notice of termination.

        6.3     LESSEE'S COMPLIANCE WITH APPLICABLE REQUIREMENTS. Except as
otherwise provided in this Lease, Lessee shall, at Lessee's sole expense, fully,
diligently and in a timely manner, materially comply with all Applicable
Requirements, the requirements of any applicable fire insurance underwriter or
rating bureau, and the recommendations of Lessor's engineers and/or consultants
which relate in any manner to the Premises, without regard to whether said
requirements are now in effect or become effective after the Start Date. Lessee
shall, within ten (10) days after receipt of Lessor's written request, provide
Lessor with copies of all permits and other documents, and other information
evidencing Lessee's compliance with any Applicable Requirements specified by
Lessor, and shall immediately upon receipt, notify Lessor in writing (with
copies of any documents involved) of any threatened or actual claim, notice,
citation, warning, complaint or report pertaining to or involving the failure of
Lessee or the Premises to comply with any Applicable Requirements.

        6.4     INSPECTION; COMPLIANCE. Lessor and Lessor's "Lender" (as defined
in Paragraph 30 below) and consultants shall have the right to enter into
Premises at any time, in the case of an emergency, and otherwise at reasonable
times, for the purpose of inspecting the condition of the Premises and for
verifying compliance by Lessee with this Lease. The cost of any such inspections
shall be paid by Lessor, unless a violation of Applicable Requirements, or a
contamination is found to exist or be imminent, or the inspection is requested
or ordered by a governmental authority. In such case, Lessee shall upon request
reimburse Lessor for the cost of such inspections, so long as such inspection is
reasonably related to the violation or contamination.

        6.5    HAZARDOUS SUBSTANCES MANAGEMENT PLAN. Lessee represents, warrants
and covenants with Lessor that Lessee will not conduct any manufacturing or
development processes on the Premises in which Hazardous Substances are used.
Except for ordinary and customary materials reasonably required to be used in
the normal course of the Agreed Use and except as set forth on Exhibit "B"
attached to this Lease and incorporated herein by reference, Lessee shall not
bring onto the Premises any Hazardous Substances. Lessee represents and warrants
to Lessor that under applicable laws and ordinances Lessee's present use of the
Premises does not require Lessee to prepare a Hazardous Substances Management
Plan. If Lessee is required to prepare a Hazardous Substances Management Plan at
any time during the term of this Lease, Lessee shall promptly deliver to Lessor
Lessee's current Hazardous Substances  Management Plan as created or
replacements thereof, from time to time during the term of this Lease, and
copies of all Hazardous Substances reports or plans filed by Lessee with the
City of Mountain View or with any other governmental agency, even though
Lessee's Hazardous Substances  Management Plan and any such reports or plans
filed with the City, or any other governmental agency, show

                                  Page 6 of 23
<PAGE>   7
that Lessee is not currently using any reportable Hazardous Substances on the
Premises.

               (c) AUDIT. Lessee or Lessee's accountants shall have the right
once each calendar year to inspect and audit Lessor's books and records relating
to any operating expenses, Taxes and insurance premiums for the Premises
incurred by Lessor for which Lessor has a right of reimbursement from Lessee
pursuant to this Lease. Unless Lessee raises any objections to any charges by
Lessor within ninety (90) days after the close of any calendar year, Lessee
shall have no right thereafter to dispute any charges for such calendar year.

               (d) MANAGEMENT FEE. Lessee shall pay to Lessor, together with
monthly Base Rent, a management fee for the operation and management of the
Premises as additional rent in an amount equal to three percent (3%) of the
monthly Base Rent payable from time to time pursuant to Paragraph 15.

        7.2     LESSOR'S OBLIGATIONS. Except as provided in Paragraph 2.3
(Compliance), Paragraph 7.1(a) (Lessee's Obligations), Paragraph 9 (Damage or
Destruction) and Paragraph 14 (Condemnation), Lessor shall be responsible for
the maintenance, repair, and replacement, when necessary, of the structural
elements of the roof (excluding the roof membrane) and the structural elements
of the foundation and exterior walls (except the interior faces thereof, unless
the need for the repair of the interior faces results from an exterior wall
structural condition), as "structural elements" are

                                  Page 7 of 23
<PAGE>   8
defined in building codes applicable to the Building, but excluding the
maintenance, repair, or replacement of any alterations, structural or otherwise,
made by Lessee to the Premises which are not approved in writing by Lessor prior
to the construction thereof. Subject to the foregoing, it is intended by the
Parties hereto that Lessor have no obligation, in any manner whatsoever, to
repair and maintain the Premises, or the equipment therein, all of which
obligations are intended to be that of the Lessee. It is the intention of the
Parties that the terms of this Lease govern the respective obligations of the
Parties as to maintenance and repair of the Premises, and they expressly waive
the benefit of any statute now or hereafter in effect to the extent it is
inconsistent with the terms of this Lease.

        7.3     UTILITY INSTALLATIONS; TRADE FIXTURES; ALTERATIONS.

               (a) DEFINITIONS; CONSENT REQUIRED. The term "UTILITY
INSTALLATIONS" refers to all floor and window coverings, air lines, power
panels, electrical distribution, security and fire protection systems,
communication systems, lighting fixtures, HVAC equipment, plumbing, and fencing
in or on the Premises. The term "TRADE FIXTURES" shall mean Lessee's machinery
and equipment that can be removed without doing material damage to the Premises.
The term "ALTERATIONS" shall mean any modification of the improvements, other
than Utility Installations or Trade Fixtures, whether by addition or deletion.
"LESSEE OWNED ALTERATIONS AND/OR UTILITY INSTALLATIONS" are defined as
Alterations and/or Utility Installations made by Lessee that are not yet owned
by Lessor pursuant to Paragraph 7.4(a). Lessee shall not make any Alterations or
Utility Installations to the Premises without Lessor's prior written consent.
Lessee may, however, make non-structural Utility Installations to the interior
of the Premises (excluding the roof) without such consent but upon notice to
Lessor, as long as they are not visible from the outside, do not involve
puncturing, relocating or removing the roof or any existing walls, and the
cumulative cost thereof during this Lease as extended does not exceed $50,000 in
the aggregate or $10,000 in any one year.

               (b) CONSENT. Any Alterations or Utility Installations that Lessee
shall desire to make and which require the consent of the Lessor shall be
presented to Lessor in written form with detailed plans. Consent shall be deemed
conditioned upon Lessee's: (i) acquiring all applicable governmental permits,
(ii) furnishing Lessor with copies of both the permits and the plans and
specifications prior to commencement of the work, and (iii) compliance with all
conditions of said permits and other Applicable Requirements in a prompt and
expeditious manner. Any Alterations or Utility Installations shall be performed
in a workmanlike manner with good and sufficient materials. Lessee shall
promptly upon completion furnish Lessor with as-built plans and specifications.
For work which costs an amount equal to the greater of one month's Base Rent, or
$10,000, Lessor may condition its consent upon Lessee providing a lien and
completion bond in an amount equal to one and one-half times the estimated cost
of such Alteration or Utility Installation and/or upon Lessee's posting an
additional Security Deposit with Lessor. Lessor may also condition Lessor's
consent to any Alterations or Utility Installations by Lessee upon the
requirement that such Alterations or Utility Installations shall be removed by
Lessee, at Lessee's expense by the expiration or termination of this Lease.

               (c) INDEMNIFICATION. 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 on the Premises, which claims are or may be secured by any
mechanic's or materialmen's lien against the Premises or any interest therein.
Lessee shall give Lessor not less than ten (10) days' notice prior to the
commencement of any work in, on or about the Premises, and Lessor shall have the
right to post notices of non-responsibility. If Lessee shall contest the
validity of any such lien, claim or demand, then Lessee shall, at its sole
expense defend and protect itself, Lessor and the Premises against the same and
shall pay and satisfy any such adverse judgment that may be rendered thereon
before the enforcement thereof. If Lessor shall require, Lessee shall furnish a
surety bond in an amount equal to one and one-half times the amount of such
contested lien, claim or demand, indemnifying Lessor against liability for the
same. If Lessor elects to participate in any such action, Lessee shall pay
Lessor's attorneys' fees and costs.

        7.4     OWNERSHIP; REMOVAL; SURRENDER; AND RESTORATION.

               (a) OWNERSHIP. Subject to Lessor's right to require removal or
elect ownership as hereinafter provided, all Alterations and Utility
Installations made by Lessee shall be the property of Lessee, but considered a
part of the Premises. Lessor may, at any time, elect in writing to be the owner
of all or any specified part of the Lessee Owned Alterations and Utility
Installations. Unless otherwise instructed per Paragraph 7.4(b) hereof, all
Lessee Owned Alterations and Utility Installations shall, at the expiration or
termination of this Lease, become the property of Lessor and be surrendered by
Lessee with the Premises.

               (b) REMOVAL. Provided that Lessor conditioned Lessor's consent to
the Alterations or Utility Installations upon the requirement that Lessee shall
remove the same and Lessee's expense by the expiration or termination of this
Lease pursuant to Paragraph 7.3(b) Lessee shall remove at Lessee's expense all
Lessee Owned Alterations or Utility Installations by the expiration or
termination of this Lease. Lessor may require the removal at any time of all or
any part of any Lessee Owned Alterations or Utility Installations made without
the required consent.

               (c) SURRENDER/RESTORATION. Lessee shall surrender the Premises by
the Expiration Date or any earlier termination date, with all of the
improvements, parts and surfaces thereof broom clean and free of debris, and in
good operating order, condition and state of repair, ordinary wear and tear
excepted. "Ordinary wear and tear" shall not include any damage or deterioration
that would have been prevented by good maintenance practice. Lessee shall repair
any damage occasioned by the installation, maintenance or removal of Trade
Fixtures, Lessee Owned Alterations and/or Utility Installations, furnishings,
and equipment as well as the removal of any storage tank installed by or for
Lessee, and the removal, replacement, or remediation of any soil, material or
groundwater contaminated by Lessee. Trade Fixtures shall remain the property of
Lessee and shall be removed by Lessee. The failure by Lessee to timely vacate
the Premises pursuant to this Paragraph 7.4(c) without the express written
consent of Lessor shall constitute a holdover under the provisions of Paragraph
26 below.

8.      INSURANCE; INDEMNITY.

                                  Page 8 of 23

<PAGE>   9
        8.1     PAYMENT FOR INSURANCE. Lessee shall pay for all insurance
required under Paragraph 8 except to the extent of the cost attributable to
liability insurance carried by Lessor under Paragraph 8.2(b) in excess of
$5,000,000 per occurrence. Premiums for policy periods commencing prior to or
extending beyond the Lease term shall be prorated to correspond to the Lease
term. Payment shall be made by Lessee to Lessor within ten (10) days following
receipt of an invoice.

        8.2     LIABILITY INSURANCE.

                (a) CARRIED BY LESSEE. Lessee shall obtain and keep in force a
Commercial General Liability Policy of Insurance protecting Lessee and Lessor
against claims for bodily injury, personal injury and property damage based upon
or arising out of the ownership, use, occupancy or maintenance of the Premises
and all areas appurtenant thereto. Such insurance shall be on an occurrence
basis providing single limit coverage in an amount not less than $3,000,000 per
occurrence with an "ADDITIONAL INSURED -- MANAGERS OR LESSORS OF PREMISES
ENDORSEMENT" and contain the "AMENDMENT OF THE POLLUTION EXCLUSION ENDORSEMENT"
for damage caused by heat, smoke or fumes from a hostile fire. The Policy shall
not contain any intra-insured exclusions as between insured persons or
organizations, but shall include coverage for liability assumed under this Lease
as an "insured contract" for the performance of Lessee's indemnity obligations
under this Lease. The limits of said insurance shall not, however, limit the
liability of Lessee nor relieve Lessee of any obligation hereunder. All
insurance carried by Lessee shall be primary to and not contributory with any
similar Insurance carried by Lessor, whose insurance shall be considered excess
insurance only. Concurrently with the execution and delivery of this Lease, and
annually within thirty (30) days after each renewal date throughout the term of
this Lease, Lessee shall deliver to Lessor evidence of Lessee's insurance
coverages in accordance with the foregoing.

                (b) CARRIED BY LESSOR. Lessor shall maintain liability insurance
as described in Paragraph 8.2(a), in addition to, and not in lieu of, the
insurance required to be maintained by Lessee. Lessee shall not be named as an
additional insured therein.

        8.3     PROPERTY INSURANCE -- BUILDING, IMPROVEMENTS AND RENTAL VALUE.

                (a) BUILDING AND IMPROVEMENTS. The Insuring Party shall obtain
and keep in force a policy or policies in the name of Lessor, with loss payable
to Lessor, any groundlessor, and to any Lender(s) insuring loss or damage to the
Premises. The amount of such insurance shall be equal to the full replacement
cost of the Premises, as the same shall exist from time to time, or the amount
required by any Lenders, but in no event more than the commercially reasonable
and available insurable value thereof. If Lessor is the Insuring Party, however,
Lessee Owned Alterations and Utility Installations, Trade Fixtures, and Lessee's
personal property shall be insured by Lessee under Paragraph 8.4 rather than by
Lessor. Such policy or policies shall insure against all risks of direct
physical loss or damage as contemplated under the "special perils" policy form
(except the perils of flood and/or earthquake unless required by a Lender),
including coverage for debris removal and the enforcement of any Applicable
Requirements requiring the upgrading demolition, reconstruction or replacement
of any portion of the Premises as a result of a covered loss. Said policy or
policies shall also contain an agreed valuation provision in lieu of any
coinsurance clause, waiver of subrogation, and inflation guard protection
causing an increase in the annual property insurance coverage amount by a factor
of not less than the adjusted U.S. Department of Labor Consumer Price Index for
All Urban Consumers for the city nearest to where the Premises are located. If
such insurance coverage has a deductible clause, the deductible amount shall not
exceed $1,000 per occurrence, and Lessee shall be liable for such deductible
amount in the event of an Insured Loss.

                (b) RENTAL VALUE. The Insuring Party shall obtain and keep in
force a policy or policies in the name of Lessor with loss payable to Lessor and
any Lender, insuring the loss of the full Rent for one (1) year. Said insurance
shall provide that in the event the Lease is terminated by reason of an insured
loss, the period of indemnity for such coverage shall be extended beyond the
date of the completion of repairs or replacement of the Premises, to provide for
one full year's loss of Rent from the date of any such loss. Said insurance
shall contain an agreed valuation provision in lieu of any coinsurance clause,
and the amount of coverage shall be adjusted annually to reflect the projected
Rent otherwise payable by Lessee, for the next twelve (12) month period. Lessee
shall be liable for any deductible amount in the event of such loss.

                (c) ADJACENT PREMISES. If the Premises are part of a larger
building, or of a group of buildings owned by Lessor which are adjacent to the
Premises, the Lessee shall pay for any increase in the premiums for the property
insurance of such building or buildings if said increase is caused by Lessee's
acts, omissions, use or occupancy of the Premises.

        8.4     LESSEE'S PROPERTY/BUSINESS INTERRUPTION INSURANCE.

                (a) PROPERTY DAMAGE. Lessee shall obtain and maintain insurance
coverage on all of Lessee's personal property, Trade Fixtures, and Lessee Owned
Alterations and Utility Installations. Such insurance shall be full replacement
cost coverage with a deductible of not to exceed $1,000 per occurrence. The
proceeds from any such insurance shall be used by Lessee for the replacement of
personal property, Trade Fixtures and Lessee Owned Alterations and Utility
Installations. Lessee shall provide Lessor with written evidence that such
insurance is in force.

                (b) NO REPRESENTATION OF ADEQUATE COVERAGE. Lessor makes no
representation that the limits or forms of coverage of insurance

                                  Page 9 of 23
<PAGE>   10
specified herein are adequate to cover Lessee's property, business operations or
obligations under this Lease.

        8.5     INSURANCE POLICIES. Insurance required herein shall be by
companies duly licensed or admitted to transact business in the state where the
Premises are located, and maintaining during the policy term a "General
Policyholders Rating" of at least B+, V, as set forth in the most current issue
of "Best's Insurance Guide", or such other rating as may be required by a
Lender. Lessee shall not do or permit to be done anything which invalidates the
required insurance policies. Lessee shall, prior to the Start Date, deliver to
Lessor certified copies of policies of such insurance or certificates evidencing
the existence and amounts of the required insurance. No such policy shall be
cancelable or subject to 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 evidence of renewals or
"insurance binders" evidencing renewal thereof, or Lessor may order such
insurance and charge the cost thereof to Lessee, which amount shall be payable
by Lessee to Lessor upon demand. Such policies shall be for a term of at least
one year, or the length of the remaining term of this Lease, whichever is less.
If either Party shall fail to procure and maintain the insurance required to be
carried by it, the other Party may, but shall not be required to, procure and
maintain the same.

        8.6     WAIVER OF SUBROGATION. Without affecting any other rights or
remedies, Lessee and Lessor each hereby release and relieve the other, and waive
their entire right to recover damages against the other, for loss of or damage
to its property arising out of or incident to the perils required to be insured
against herein. The effect of such releases and waivers is not limited by the
amount of insurance carried or required, or by any deductibles applicable
hereto.

        8.7     INDEMNITY. Except for Lessor's gross negligence or willful
misconduct (and except that Lessee's indemnification with respect to Hazardous
Substances shall be governed by Paragraph 6.2(d)). Lessee shall indemnify,
protect, defend and hold harmless the Premises, Lessor and its agents, Lessor's
master or ground lessor, partners and Lenders, from and against any and all
claims, loss of rents and/or damages, liens, judgments, penalties, attorneys'
and consultants' fees, expenses and/or liabilities arising out of, involving, or
in connection with, the use and/or occupancy of the Premises by Lessee. If any
action or proceeding is brought against Lessor by reason of any of the foregoing
matters, Lessee shall upon notice 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 defended
or indemnified.

        8.8     EXEMPTION OF LESSOR FROM LIABILITY. Lessor shall not be liable
for injury or damage to the person or goods, wares, merchandise or other
property of Lessee, Lessee's employees, contractors, invitees, customers, or any
other person in or about the Premises, whether such damage or injury is caused
by or results from fire, steam, electricity, gas, water or rain, or from the
breakage, leakage, obstruction or other defects of pipes, fire sprinklers,
wires, appliances, plumbing, HVAC or lighting fixtures, or from any other cause,
whether the said injury or damage results from conditions arising upon the
Premises or upon other portions of the Building of which the Premises are a
part, or from other sources or places. Lessor shall not be liable for any
damages arising from any act or neglect of any other tenant of Lessor.
Notwithstanding Lessor's negligence or breach of this Lease, Lessor shall under
no circumstances be liable for injury to Lessee's business or for any loss of
income or profit therefrom.

9.      DAMAGE OR DESTRUCTION.

        9.1     DEFINITIONS.

                (a) "PREMISES PARTIAL DAMAGE" shall mean damage or destruction
to the improvements on the Premises, other than Lessee Owned Alterations and
Utility Installations, which can reasonably be repaired in six (6) months or
less from the date of the damage or destruction. Lessor shall notify Lessee in
writing within thirty (30) days from the date of the damage or destruction as to
whether or not the damage is Partial or Total.

                (b) "PREMISES TOTAL DESTRUCTION" shall mean damage or
destruction to the Premises, other than Lessee Owned Alterations and Utility
Installations and Trade Fixtures, which cannot reasonably be repaired in six (6)
months or less from the date of the damage or destruction. Lessor shall notify
Lessee in writing within thirty (30) days from the date of the damage or
destruction as to whether or not the damage is Partial or Total.

                (c) "INSURED LOSS" shall mean damage or destruction to
improvements on the Premises, other than Lessee Owned Alterations and Utility
Installations and Trade Fixtures, which was caused by an event required to be
covered by the insurance described in Paragraph 8.3(a), irrespective of any
deductible amounts or coverage limits involved.

                (d) "REPLACEMENT COST" shall mean the cost to repair or rebuild
the improvements owned by Lessor at the time of the occurrence to their
condition existing immediately prior thereto, including demolition, debris
removal and upgrading required by the operation of Applicable Requirements, and
without deduction for depreciation.

                (e) "HAZARDOUS SUBSTANCE CONDITION" shall mean the occurrence or
discovery of a condition involving the presence of, or a contamination by, a
Hazardous Substance as defined in Paragraph 6.2(a), in, on, or under the
Premises.

        9.2     PARTIAL DAMAGE -- INSURED LOSS. If a Premises Partial Damage
that is an Insured Loss occurs, then Lessor shall, at Lessor's expense, repair
such damage (but not Lessee's Trade Fixtures or Lessee Owned Alterations and
Utility Installations) as soon as reasonably possible and this Lease shall
continue in full force and effect; provided, however, that Lessee shall, at
Lessor's election, make the repair of any damage or destruction the total cost
to repair of which is $10,000 or less, and, in such event, Lessor shall make any
applicable insurance proceeds available to Lessee on a reasonable basis for that
purpose. Notwithstanding the foregoing, if the required insurance was not in
force or the insurance proceeds are not sufficient to effect such repair, the
Insuring Party shall promptly contribute the shortage in proceeds (except as to
the deductible which is Lessee's responsibility) as and when required to
complete said repairs. In the event, however, such shortage was due to the fact
that, by reason of the unique nature of the improvements, full replacement cost
insurance coverage was not commercially reasonable and available, Lessor shall
have no obligation to pay for the shortage in insurance proceeds or to fully
restore the unique aspects of the Premises unless Lessee provides Lessor with
the funds to cover same, or adequate assurance thereof, within ten (10) days
following receipt of written notice of such shortage and request therefor. If
Lessor receives said funds or adequate assurance thereof within said ten (10)
day period, the party responsible for making the repairs shall complete them as
soon as reasonably possible and this Lease shall remain in full force and
effect. If such funds or assurance are not received, Lessor may nevertheless
elect by written notice to Lessee within ten (10) days thereafter to: (i) make
such restoration and repair as is commercially reasonable with Lessor paying any
shortage in proceeds, in which case this Lease shall remain in full force and
effect, or have this Lease terminate thirty (30) days thereafter. Lessee shall
not be entitled to reimbursement of any funds contributed by Lessee to repair
any such damage or destruction. Premises Partial Damage due to flood or
earthquake shall be subject to Paragraph 9.3, notwithstanding that there may be
some insurance coverage, but the net proceeds of any such insurance shall be
made available for the repairs if made by either Party.

        9.3     PARTIAL DAMAGE -- UNINSURED LOSS. If a Premises Partial Damage
that is not an Insured Loss occurs, unless caused by a negligent or willful act
of Lessee (in which event Lessee shall make the repairs at Lessee's expense),
Lessor may either: (i) repair such damage as soon as reasonably

                                 Page 10 of 23
<PAGE>   11
possible at Lessor's expense, in which event this Lease shall continue in full
force and effect, or (ii) terminate this Lease by giving written notice to
Lessee within thirty (30) days after receipt by Lessor of knowledge of the
occurrence of such damage. Such termination shall be effective sixty (60) days
following the date of such notice. In the event Lessor elects to terminate this
Lease, Lessee shall have the right within ten (10) days after receipt of the
termination notice to give written notice to Lessor of Lessee's commitment to
pay for the repair of such damage without reimbursement from Lessor. Lessee
shall provide Lessor with said funds or satisfactory assurance thereof within
thirty (30) days after making such commitment. In such event this Lease shall
continue in full force and effect, and Lessor shall proceed to make such repairs
as soon as reasonably possible after the required funds are available. If Lessee
does not make the required commitment, this Lease shall terminate as of the date
specified in the termination notice.

        9.4     TOTAL DESTRUCTION. Notwithstanding any other provision hereof,
if a Premises Total Destruction occurs, this Lease shall terminate sixty (60)
days following such Destruction. If the damage or destruction was caused by the
gross negligence or willful misconduct of Lessee, Lessor shall have the right to
recover Lessor's damages from Lessee, except as provided in Paragraph 8.6.

        9.5     DAMAGE NEAR END OF TERM. If at any time during the last six (6)
months of this Lease there is damage for which the cost to repair exceeds one
(1) month's Base Rent, whether or not an Insured Loss, Lessor may terminate this
Lease effective sixty (60) days following the date of occurrence of such damage
by giving a written termination notice to Lessee within thirty (30) days after
the date of occurrence of such damage. Notwithstanding the foregoing, if Lessee
at that time has an exercisable option to extend this Lease or to purchase the
Premises, then Lessee may preserve this Lease by, (a) exercising such option and
(b) providing Lessor with any shortage in insurance proceeds (or adequate
assurance thereof) needed to make the repairs on or before the earlier of (i)
the date which is ten days after Lessee's receipt of Lessor's written notice
purporting to terminate this Lease, or (ii) the day prior to the date upon which
such option expires. If Lessee duly exercises such option during such period and
provides Lessor with funds (or adequate assurance thereof) to cover any shortage
in insurance proceeds, Lessor shall, at Lessor's commercially reasonable
expense, repair such damage as soon as reasonably possible and this Lease shall
continue in full force and effect. If Lessee fails to exercise such option and
provide such funds or assurance during such period, then this Lease shall
terminate on the date specified in the termination notice and Lessee's option
shall be extinguished.

        9.6     ABATEMENT OF RENT; LESSEE'S REMEDIES.

                (a) ABATEMENT. In the event of Premises Partial Damage or
Premises Total Destruction or a Hazardous Substance Condition, the Rent payable
by Lessee for the period required for the repair, remediation or restoration of
such damage shall be abated in proportion to the degree to which Lessee's use of
the Premises is impaired, but not to exceed the proceeds received from the
Rental Value insurance. All other obligations of Lessee hereunder shall be
performed by Lessee, and Lessor shall have no liability for any such damage,
destruction, remediation, repair or restoration except as provided herein. The
Rent payable be Lessee shall also be abated, to the extent and upon the
conditions set forth in the first sentence of this Paragraph 9.6(a), if (i)
Lessee's use of the Premises is impaired due to off-premises interruption of
utilities services to the Premises, and (ii) Lessor's Rental Value insurance
coverage includes an endorsement which covers such risk, but Lessor shall not be
obligated to obtain such endorsement or to maintain such endorsement in effect.

                (b) REMEDIES. If Lessor shall be obligated to repair or restore
the Premises and does not commence, in a substantial and meaningful way, such
repair or restoration within ninety (90) days after such obligation shall
accrue, Lessee may, at any time prior to the commencement of such repair or
restoration, give written notice to Lessor and to any Lenders of which Lessee
has actual notice, of Lessee's election to terminate this Lease on a date not
less than sixty (60) days following the giving of such notice. If Lessee gives
such notice and such repair or restoration is not commenced within thirty (30)
days thereafter, this Lease shall terminate as of the date specified in said
notice. If the repair or restoration is commenced within said thirty (30) days,
this Lease shall continue in full force and effect. "COMMENCE" shall mean either
the unconditional authorization of the preparation of the required plans, or the
beginning of the actual work on the Premises, whichever first occurs.

        9.7     TERMINATION -- ADVANCE PAYMENTS. Upon termination of this Lease
pursuant to Paragraph 6.2(g) or Paragraph 9, an equitable adjustment shall be
made concerning advance Base Rent and any other advance payments made by Lessee
to Lessor. Lessor shall, in addition, return to Lessee so much of Lessee's
Security Deposit as has not been, or is not then required to be, used by Lessor.

        9.8     WAIVE STATUTES. Lessor and Lessee agree that the terms of this
Lease shall govern the effect of any damage to or destruction of the Premises
with respect to the termination of this Lease and hereby waive the provisions of
any present or future statute to the extent inconsistent herewith.

10.     REAL PROPERTY TAXES.

        10.1    DEFINITION OF "REAL PROPERTY TAXES." As used herein, the term
"REAL PROPERTY TAXES" shall include any form of assessment; real estate,
general, special, ordinary or extraordinary, or rental levy or tax (other than
inheritance, personal income or estate taxes); improvement bond; and/or license
fee imposed upon or levied against any legal or equitable interest of Lessor in
the Premises, Lessor's right to other income therefrom, and/or Lessor's business
of leasing, by any authority having the direct or indirect power to tax and
where the funds are generated with reference to the Building address and where
the proceeds so generated are to be applied by the city, county or other local
taxing authority of a jurisdiction within which the Premises are located. The
term "REAL PROPERTY TAXES" shall also include any tax, fee, levy, assessment or
charge, or any increase therein, imposed by reason of events occurring during
the term of this Lease, including but not limited to, a change in the ownership
of the Premises which occurs after April 30, 2002 Lessor agrees that Real
Property Taxes will not include increases in Real Property Taxes resulting from
a reassessment following a change of ownership prior to May 1, 2002.

        10.2

                (a) PAYMENT OF TAXES. Lessee shall pay the Real Property Taxes
applicable to the Premises during the term of this Lease. Subject to Paragraph
10.2(b), all such payments shall be made at least ten (10) days prior to any
delinquency date. Lessee shall promptly furnish Lessor with satisfactory
evidence that such taxes have been paid. If any such taxes shall cover any
period of time prior to or after the expiration or termination of this Lease,
Lessee's share of such taxes shall be prorated to cover only that portion of the
tax bill applicable to the period that this Lease is in effect, and Lessor

                                 Page 11 of 23

<PAGE>   12
shall reimburse Lessee for any overpayment. If Lessee shall fail to pay any
required Real Property Taxes, Lessor shall have the right to pay the same, and
Lessee shall reimburse Lessor therefor upon demand. With respect to any
assessment levied against the Premises which under the laws then in force may
be paid in installments, only the amount of such installments and statutory
interest applicable to the period of this Lease (with appropriate proration of
any partial year) shall be included in the definition of Real Property Taxes,
whether or not Lessor elects to pay such assessment in installments.

                (b) ADVANCE PAYMENT. In the event Lessee incurs a late charge on
any Rent payment, Lessor may, at Lessor's option, estimate the current Real
Property Taxes, and require that such taxes be paid in advance to Lessor by
Lessee, either: (i) in a lump sum amount equal to the installment due, at least
twenty (20) days prior to the applicable delinquency date, or (ii) monthly in
advance with the payment of the Base Rent. If Lessor elects to require payment
monthly in advance, the monthly payment shall be an amount equal to the amount
of the estimated installment of taxes divided by the number of months remaining
before the month in which said installment becomes delinquent. When the actual
amount of the applicable tax bill is known, the amount of such equal monthly
advance payments shall be adjusted as required to provide the funds needed to
pay the applicable taxes. If the amount collected by Lessor is insufficient to
pay such Real Property Taxes when due, Lessee shall pay Lessor, upon demand,
such additional sums as are necessary to pay such obligations. All monies paid
to Lessor under this Paragraph may be intermingled with other monies of Lessor
and shall not bear interest. In the event of a Breach by Lessee in the
performance of its obligations under this Lease, then any balance of funds paid
to Lessor under the provisions of this Paragraph may, at the option of Lessor,
be treated as an additional Security Deposit.

        10.3    JOINT ASSESSMENT. If the Premises are not separately assessed,
Lessee's liability shall be an equitable proportion of the Real Property Taxes
for all of the land and improvements included within the tax parcel assessed,
such proportion to be conclusively determined by Lessor from the respective
valuations assigned in the assessor's work sheets or such other information as
may be reasonably available.

        10.4    PERSONAL PROPERTY TAXES. Lessee shall pay, prior to delinquency,
all taxes assessed against and levied upon Lessee Owned Alterations, Utility
Installations, Trade Fixtures, furnishings, equipment and all personal property
of Lessee. When possible, Lessee shall cause such property to be assessed and
billed separately from the real property of Lessor. If any of Lessee's said
personal property shall be assessed with Lessor's real property, Lessee shall
pay Lessor the taxes attributable to Lessee's property within ten (10) days
after receipt of a written statement. Lessee may contest by appropriate
proceeding the amount or validity of any personal property taxes assessed
against and levied upon Lessee's personal property; provided, that Lessee shall
promptly pay such taxes unless such proceeding shall operate to prevent or stay
the collection of the tax so contested. Lessee shall indemnify Lessor against
any liability, cost, or expense, including, without limitation attorneys' fees
and costs in connection with any such contest by Lessee.

11.     UTILITIES. Lessee shall pay for all water, gas, heat, light, power,
telephone, trash disposal and other utilities and services supplied to the
Premises, together with any taxes thereon. If any such services are not
separately metered to Lessee, Lessee shall pay a reasonable proportion, to be
determined by Lessor, of all charges jointly metered.

12.     ASSIGNMENT AND SUBLETTING.

                (a) Except as provided in Paragraph 12(g), Lessee shall not
assign this Lease, or any interest therein, voluntarily or involuntarily, and
shall not sublet the Premises or any part thereof or any right or privilege
appurtenant thereto, or suffer any other person (the agents and servants of
Lessee excepted) to occupy or use the Premises, or any portion thereof, without
the prior written consent of Lessor in each instance pursuant to the terms and
conditions set forth below which consent shall not be unreasonably withheld,
subject to the following provisions.

                (b) Subject to the provisions of this Paragraph 12, Lessee
shall have the right to sublease separately (i) the entire Building, (ii) the
two story portion of the Building, or (iii) the one story portion of the
Building (but not part of the two story portion of the Building or part of the
one story portion of the Building). In the event of an approved sublease of the
two story portion of the Building or the one story portion of the Building, the
demising area shall be the main entrance to the Building.

                (c) Notwithstanding the provisions of Paragraph 12(b), in the
case of a proposed assignment or subletting by Lessee of (i) the entire
Building, (ii) the two story portion, or (iii) the one story portion for the
entire balance of the term of this Lease (or for the entire balance of the

                                 Page 12 of 23
<PAGE>   13
term of this Lease except for final six (6) months or less), Lessor shall have
the right to terminate this Lease by giving written notice to Lessee and
specifying the effective date of termination pertaining to the area so
designated in Lessee's request which is the subject to the proposed assignment
or sublease.

                (d) At least thirty (30) days prior to the proposed effective
date of any assignment or sublease which Lessee desires to make, Lessee shall
provide to Lessor in writing the name and address of the proposed assignee or
sublessee, and true and complete copies of all documents relating to Lessee's
prospective agreement to assign or sublease, a copy of a current financial
statement for such proposed assignee or sublessee, and shall specify all
consideration to be received by Lessee for such assignment or sublease in the
form of lump sum payments installments of rent, or otherwise. For purposes of
this Paragraph 12, the term "consideration" shall include all money or other
consideration to be received by Lessee for such assignment or sublease. Within
fifteen (15) days after the receipt of such documentation and other information
Lessor shall (1) notify Lessee in writing that Lessor elects to consent to the
proposed assignment or sublease subject to the terms and conditions set forth
herein; or (2) notify Lessee in writing that Lessor refuses such consent,
specifying reasonable grounds for such refusal; or (3) if the proposed
transaction is an assignment of this Lease, or a sublease and is of (i) the
entire Building (ii) the two story portion, or (iii) the one story portion for
the entire balance of the term of this Lease (or for the entire balance of the
term of this Lease except for the final six (6) months or less). Lessor shall
have the right to terminate this Lease by giving written notice to Lessee and
specifying the effective date of termination and recapture which shall be the
date on which the proposed assignment or sublease transaction was otherwise to
be effective, and specifying the Premises pertaining to the area so designated
in Lessee's request which is the subject to the proposed assignment or
sublease. If Lessor elects to terminate this Lease as to the entire Building or
as to a portion of the Building in accordance with the foregoing provision, as
of the effective date of termination, Lessor and Lessee shall each be released
and discharged from any liability or obligation to the other under this Lease
accruing thereafter as to the portion of the Building with respect to which
this Lease is terminated, and Lessee agrees that Lessor may enter into a direct
lease with such proposed assignee or sublessee without any obligation or
liability to Lessee.

        In deciding whether to consent to any proposed assignment or sublease,
Lessor may take into account whether or not reasonable conditions, including,
but not limited to, the following, have been satisfied:

                (1) In Lessor's reasonable judgment, the proposed assignee or
subtenant is engaged in such a business, that the Premises, or the relevant
part thereof, will be used in such a manner which complies with Paragraph 1.8
and Paragraph 6 hereof entitled "Use";

                (2) The proposed assignee or subtenant is a reputable entity or
individual with sufficient financial net worth so as to reasonably indicate
that it will be able to meet its obligations under this Lease or the sublease
in a timely manner; and

                                 Page 13 of 23

<PAGE>   14
          (3)  The proposed assignment or sublease is approved by Lessor's
mortgage lender if such lender has the right to approve or disapprove proposed
assignments or subleases.

     (e)  As a condition to Lessor's granting its consent to any assignment or
sublease, (1) Lessor may require that Lessee pay to Lessor, as and when
received by Lessee, seventy-five percent (75%) of the amount of any excess of
the consideration to be received by Lessee in connection with said assignment
or sublease over and above the rental amount fixed by this Lease and payable by
Lessee to Lessor, after deducting only (A) actual leasing commissions incurred
by Lessee in consummating such assignment or sublease which are reasonably
approved by Lessor and (B) Lessor's and Lessee's reasonable attorneys' fees
incurred in connection with the negotiation, review, and documentation of the
assignment or sublease, provided that such deduction for either Lessor's or
Lessee's attorneys' fees shall not exceed $2,000. Items (A) and (B) shall be
amortized in equal monthly installments over the balance of the term of this
Lease if an assignment or over the term of the sublease, if a sublease; and (2)
Lessee and the proposed assignee or sublessee shall demonstrate to Lessor's
reasonable satisfaction that each of the criteria referred to in Paragraph 12(d)
above is satisfied.

     (f)  Lessee shall reimburse Lessor upon demand for reasonable attorneys'
fees incurred by Lessor in connection with the negotiation, review, and
documentation of any requested assignment or sublease. Said amount shall be
treated as a cost to be deducted from the overage rent pursuant to Paragraph
12(e).

     (g)  Notwithstanding the foregoing, Lessee may, without Lessor's prior
written consent, without Lessor having the right to terminate this Lease and
recapture the Premises pursuant to Paragraph 12(d)(3), and without participation
by Lessor in assignment or subletting proceeds, sublet a portion or the entire
Premises or assign this Lease (1) to an entity controlled by controlling, or
under the common control with Lessee ("affiliate"), or (2) in connection with a
merger, consolidation, or sale of all or substantially all of the assets or
stock of Lessee ("reorganization"); provided, that (A) in the case of an
assignment or subletting to an affiliate, or in the case of a reorganization in
which Marimba, Inc. is the surviving entity, Marimba, Inc. shall remain
primarily liable to Lessor hereunder; and (B) in the case of a reorganization
in which Marimba, Inc. is not the surviving entity, the surviving entity or the
transferee, as the case may be, shall expressly assume in writing and agree to
perform all of Lessee's obligations under this Lease including, but not limited
to, the payment of Rent; and (C) in the case of either an assignment or sublease
to an affiliate or an assignment or sublease in connection with a
reorganization, at lease thirty (30) days prior to the effective date of such
assignment or sublease, Lessee shall provide to Lessor in writing the name and
address of the proposed assignee or sublessee, and true and complete copies of
all documents relating to Lessee's prospective agreement to assign or sublease,
and a copy of current financial statement for such proposed assignee or
sublessee; and (D) in the case of an assignment or sublease in connection with
a reorganization in which Marimba, Inc. is not the surviving entity, the
Security Deposit shall be increased to an amount equal to four (4) months of
the then prevailing monthly Base Rent unless Lessee is able to demonstrate to

                                 Page 14 of 23
<PAGE>   15
Lessor's reasonable satisfaction that the net worth of the assignee or successor
immediately after the effective date of the transaction is not or will not be
less than that of Lessee immediately prior to such transaction. "Net Worth"
shall mean net worth established under generally accepted accounting principles.

     (h)  Each assignment or sublease agreement to which Lessor has consented
(or to which Lessor's consent is not required pursuant to Paragraph 12(g)) shall
be an instrument in writing in form satisfactory to Lessor, and shall be
executed by both Lessee and the assignee or sublessee as the case may be. Each
such assignment or sublease agreement shall recite that it is and shall be
subject and subordinate to the provisions of this Lease, that the assignee or
sublessee accepts such assignment or sublease, that Lessor's consent thereto
shall not constitute a consent to any subsequent assignment or subletting by
lessee or the assignee or sublessee, and, except as otherwise set forth in a
sublease approved by Lessor, agree to perform all of the obligations of Lessee
hereunder (to the extent such obligations relate to the portion of the Premises
assigned or subleased), and that the termination of this Lease shall, at
Lessor's sole election, constitute a termination of all subleases.

     (i)  In the event Lessor shall consent to an assignment or sublease, Lessee
shall nonetheless remain primarily liable to Lessor for all obligations and
liabilities of Lessee under this Lease, including, but not limited, to the
payment of Rent.

     (j)  Lessee hereby stipulates that the foregoing terms and conditions are
reasonable and comply with California Civil Code Section 1951.4.

     (k)  Subject to the provisions of this Paragraph 12, and assignment or
sublease without Lessor's prior written consent shall at Lessor's election be
void. The consent by Lessor to any assignment or sublease shall not constitute a
waiver of the provisions of this Paragraph 12 including the requirement of
Lessor's prior written consent, with respect to any subsequent assignment or
sublease. If Lessee shall purport to assign this Lease, or sublease all or any
portion of the Premises, or permit any person or persons other than Lessee to
occupy the Premises without Lessor's prior written consent (if such consent is
required hereunder), Lessor may collect rent from the person or persons then or
thereafter occupying the Premises and apply the net amount collected to the rent
reserved herein, but no such collection shall be deemed a waiver of Lessor's
rights and remedies under this Paragraph 12, or the acceptance of any such
purported assignee, sublessee, or occupant, or a release of Lessee from the
further performance by Lessee of covenants on the part of Lessee herein
contained.

     (l)  Lessee shall not hypothecate or encumber its interest under this Lease
or any rights of Lessee hereunder, without Lessor's prior written consent which
consent Lessor may grant or withhold in Lessor's absolute discretion without any
liability to Lessee. Lessee's granting of any such lien or encumbrance shall
constitute an assignment for purposes of this Paragraph 12.

     (m)  In the event of any sale or exchange of the Premises by Lessor and
assignment of this Lease by Lessor, Lessor shall, upon providing Lessee with
written confirmation that Lessor has delivered any security deposit held by
Lessor to Lessor's successor in interest, be and hereby

                                 Page 15 of 23

<PAGE>   16
is entirely relieved of all liability under any and all of Lessor's covenants
and obligations contained in or derived from this Lease with respect to the
period commencing with the consummation of the sale or exchange and assignment.

          (n) The parties acknowledge that Lessor has the remedy described in
California Civil Code Section 1951.4 (Lessor may continue the Lease in effect
after Lessee's breach and abandonment and recover rent as it becomes due, if
Lessee has the right to sublet or assign, subject only to reasonable
limitations).

 13.     DEFAULT; BREACH; REMEDIES.

        13.1    DEFAULT; BREACH. A "DEFAULT" is defined as a failure by the
Lessee to comply with or perform any of the terms, covenants, conditions or
rules under this Lease. A "BREACH" is defined as the occurrence of one or more
of the following Defaults, and the failure of Lessee to cure such Default within
any applicable grace period:

                (a) The abandonment of the Premises; or the vacating of the
Premises without providing a commercially reasonable level of security, or where
the coverage of the property insurance described in Paragraph 8.3 is jeopardized
as a result thereof, or without providing reasonable assurances to minimize
potential vandalism.

                (b) The failure of Lessee to make any payment of Rent or any
Security Deposit required to be made by Lessee hereunder, whether to Lessor or
to a third party, when due, to provide reasonable evidence of insurance or
surety bond, or to fulfill any obligation under this Lease which endangers or
threatens life or property, where such failure continues for a period of three
(3) business days following written notice to Lessee.

                (c) The failure by Lessee to provide (i) reasonable written
evidence of compliance with Applicable Requirements, (ii) the service contracts,
(iii) the rescission of an unauthorized assignment or subletting, (iv) a Tenancy
Statement, (v) a requested subordination, (vi) evidence concerning any guaranty
and/or Guarantor, (vii) any document requested under Paragraph 42 (easements),
or (viii) any other documentation or information which Lessor may reasonably
require of Lessee under the terms of this Lease, where any such failure
continues for a period of ten (10) days following written notice to Lessee.

                (d) A Default by Lessee as to the terms, covenants, conditions
or provisions of this Lease, or of the rules adopted under Paragraph 40 hereof,
other than those described in subparagraphs 13.1(a), (b) or (c), above, where
such Default continues for a period of thirty (30) days after written notice;
provided, however, that if the nature of Lessee's Default is such that more than
thirty (30) days are reasonably required for its cure, then it shall not be
deemed to be a Breach if Lessee commences such cure within said thirty (30) day
period and thereafter diligently prosecutes such cure to completion.

                (e) The occurrence of any of the following events: (i) the
making of any general arrangement or assignment for the benefit of creditors;
(ii) becoming a "DEBTOR" as defined in 11 U.S.C. Section 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; provided, however, in the event that any
provision of this subparagraph 13.1 (e) is contrary to any applicable law, such
provision shall be of no force or effect, and not affect the validity of the
remaining provisions.

                (f) The discovery that any financial statement of Lessee or of
any Guarantor given to Lessor was materially false.

                (g) If the performance of Lessee's obligations under this Lease
is guaranteed: (i) the death of a Guarantor; (ii) the termination of a
Guarantor's liability with respect to this Lease other than in accordance with
the terms of such guaranty; (iii) a Guarantor's becoming insolvent or the
subject of a bankruptcy filing; (iv) a Guarantor's refusal to honor the
guaranty; or (v) a Guarantor's breach of its guaranty obligation on an
anticipatory basis, and Lessee's failure, within sixty (60) days following
written notice of any such event, to provide written alternative assurance or
security, which, when coupled with the then existing resources of Lessee, equals
or exceeds the combined financial resources of Lessee and the Guarantors that
existed at the time of execution of this Lease.

        13.2    REMEDIES. If Lessee fails to perform any of its affirmative
duties or obligations, within ten (10) days after written notice (or in case of
an emergency, without notice), Lessor may, at its option, perform such duty or
obligation on Lessee's behalf, including but not limited to the obtaining of
reasonably required bonds, insurance policies, or governmental licenses, permits
or approvals. The costs and expenses of any such performance by Lessor shall be
due and payable by Lessee upon receipt of invoice therefor. If any check given
to Lessor by Lessee shall not be honored by the bank upon which it is drawn,
Lessor, at its option, may require all future payments to be made by Lessee to
be by cashier's check. In the event of a Breach, Lessor may, with or without
further notice or demand, and without limiting Lessor in the exercise of any
right or remedy which Lessor may have by reason of such Breach:

                (a) Terminate Lessee's right to possession of the Premises by
any lawful means, in which case this Lease shall terminate and Lessee shall
immediately surrender possession to Lessor. In such event Lessor shall be
entitled to recover from Lessee: (i) the unpaid Rent which had been earned at
the time of termination; (ii) the worth at the time of award of the amount by
which the unpaid rent which would have been earned after termination until the
time of award exceeds the amount of such rental loss that the Lessee proves
could have been reasonably avoided; (iii) the worth at the time of award of the
amount by which the unpaid rent for the balance of the term after the time of
award exceeds the amount of such rental loss that the Lessee proves could be
reasonably avoided; and (iv) any other amount necessary to compensate Lessor for
all the detriment proximately caused by the Lessee's failure to perform its
obligations under this Lease or which in the ordinary course of things would be
likely to result therefrom, including but not limited to the cost of recovering
possession of the Premises, expenses of reletting, including necessary repairs
to the Premises, reasonable attorneys' fees, and that portion of any leasing
commission paid by Lessor in connection with this Lease applicable to the
unexpired term of this Lease. The worth at the time of award of the amount
referred to in provision (iii) of the immediately preceding sentence shall be
computed by discounting such amount at the discount rate of the Federal Reserve
Bank of the District within which the Premises are located at the time of award
plus one percent (1%). Efforts by Lessor to mitigate damages caused by Lessee's
Breach of this Lease shall not waive Lessor's right to recover damages under
Paragraph 12. If termination of this Lease is obtained through the provisional
remedy of unlawful detainer, Lessor shall have the right to recover in such
proceeding any unpaid Rent and damages as are recoverable therein, or Lessor may
reserve the right to recover all or any part thereof in a separate suit. If a
notice and grace period required under Paragraph 13.1 was not previously given,
a notice to pay rent or quit, or to perform or quit given to Lessee under the
unlawful detainer statute shall also constitute the notice required by Paragraph
13.1. In such case, the applicable grace period required by Paragraph 13.1 and
the unlawful detainer statute shall run concurrently, and the failure of Lessee
to cure the Default within the greater of the two such grace periods shall
constitute both an unlawful detainer and a Breach of this Lease entitling Lessor
to the remedies provided for in this Lease and/or by said statute.

                (b) Continue the Lease and Lessee's right to possession and
recover the Rent as it becomes due, in which event Lessee may sublet or assign,
subject only to reasonable limitations. Acts of maintenance, efforts to relet,
and/or the appointment of a receiver to protect the Lessor's interests,

                                 Page 17 of 23
<PAGE>   18
shall not constitute a termination of the Lessee's right to possession.

                (c) Pursue any other remedy now or hereafter available under the
laws or judicial decisions of the state wherein the Premises are located. The
expiration or termination of this Lease and/or the termination of Lessee's right
to possession shall not relieve Lessee from liability under any indemnity
provisions of this Lease as to matters occurring or accruing during the term
hereof or by reason of Lessee's occupancy of the Premises.

        13.3    INDUCEMENT RECAPTURE. Any agreement for free or abated rent or
other charges, or for the giving or paying by Lessor to or for Lessee of any
cash or other bonus, inducement or consideration for Lessee's entering into this
Lease, all of which concessions are hereinafter referred to as "INDUCEMENT
PROVISIONS," shall be deemed conditioned upon Lessee's full and faithful
performance of all of the terms, covenants and conditions of this Lease. Upon
Breach of this Lease by Lessee, any such Inducement Provision shall
automatically be deemed deleted from this Lease and of no further force or
effect, and any rent, other charge, bonus, inducement or consideration
theretofore abated, given or paid by Lessor under such an Inducement Provision
shall be immediately due and payable by Lessee to Lessor, notwithstanding any
subsequent cure of said Breach by Lessee. The acceptance by Lessor of Rent or
the cure of the Breach which initiated the operation of this paragraph shall not
be deemed a waiver by Lessor of the provisions of this paragraph unless
specifically so stated in writing by Lessor at the time of such acceptance.
Notwithstanding the foregoing, the Tenant Improvement Allowance contributed by
Lessor shall not be included within the term "Inducement Provisions."

        13.4    LATE CHARGES. Lessee hereby acknowledges that late payment by
Lessee of Rent 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 upon Lessor by any Lender. Accordingly, if any Rent
shall not be received by Lessor within five (5) days after such receipt by
Lessee of written notice from Lessor that such amount is due, then, Lessee shall
pay to Lessor a one-time late charge equal to six percent (6%) of each 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 such late
payment. Acceptance of such late charge by Lessor shall in no event constitute a
waiver of Lessee's Default or Breach with respect to such overdue amount, nor
prevent the exercise of any of the other rights and remedies granted hereunder.
In the event that a late charge is payable hereunder, whether or not collected,
for three (3) consecutive installments of Base Rent, then notwithstanding any
provision of this Lease to the contrary, Base Rent shall, at Lessor's option,
become due and payable quarterly in advance.

        13.5    INTEREST. Any monetary payment due Lessor hereunder, other than
late charges, not received by Lessor, when due as to scheduled payments (such as
Base Rent) or within thirty (30) days following the date on which it was due for
non-scheduled payment, shall bear interest from the date when due, as to
scheduled payments, or the thirty-first (31st) day after it was due as to
non-scheduled payments. The interest ("Interest") charged shall be equal to the
prime rate reported in the Wall Street Journal as published closest prior to the
date when due plus four percent (4%), but shall not exceed the maximum rate
allowed by law. Interest is payable in addition to the potential late charge
provided for in Paragraph 13.4.

        13.6    BREACH BY LESSOR.

                (a) NOTICE OF BREACH. Lessor shall not be deemed in breach of
this Lease unless Lessor fails within a reasonable time to perform an obligation
required to be performed by Lessor. For purposes of this Paragraph, a reasonable
time shall in no event be less than thirty (30) days after receipt by Lessor,
and any Lender whose name and address shall have been furnished Lessee in
writing for such purpose, of written notice specifying wherein such obligation
of Lessor has not been performed; provided, however, that if the nature of
Lessor's obligation is such that more than thirty (30) days are reasonably
required for its performance, then Lessor shall not be in breach if performance
is commenced within such thirty (30) day period and thereafter diligently
pursued to completion.

                (b) PERFORMANCE BY LESSEE ON BEHALF OF LESSOR. In the event that
neither Lessor nor Lender cures said breach within thirty (30) days after
receipt of said notice, or if having commenced said cure they do not diligently
pursue it to completion, then Lessee may elect to cure said breach at Lessee's
expense and offset from Rent an amount equal to the greater of one month's Base
Rent or the Security Deposit, and to pay an excess of such expense under
protest, reserving Lessee's right to reimbursement from Lessor. Lessee shall
document the cost of said cure and supply said documentation to Lessor.

14.     CONDEMNATION. If the Premises or any portion thereof are taken under the
power of eminent domain or sold under the threat of the exercise of said power
(collectively "CONDEMNATION"), this Lease shall terminate as to the part taken
as of the date the condemning authority takes title or possession, whichever
first occurs. If more than ten percent (10%) of any building portion of the
Premises, or more than twenty-five percent (25%) of the land area portion of the
Premises not occupied by any building, is taken by Condemnation, Lessee may, at
Lessee's option, to be exercised in writing within ten (10) days after Lessor
shall have given Lessee written notice of such taking (or in the absence of such
notice, within ten (10) days after the condemning authority shall have taken
possession) 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 Base Rent shall be reduced in proportion
to the reduction in utility of the Premises caused by such Condemnation.
Condemnation awards and/or payments shall be the property of Lessor, whether
such award shall be made as compensation for diminution in value of the
leasehold, the value of the part taken, or for severance damages; provided,
however, that Lessee shall be entitled to any compensation for Lessee's
relocation expenses, loss of business goodwill and/or Trade Fixtures, without
regard to whether or not this Lease is terminated pursuant to the provisions of
this Paragraph. All Alterations and Utility Installations made to the Premises
by Lessee, for purposes of Condemnation only, shall be considered the property

the Condemnation, Lessor shall repair any damage to the Premises caused by such
Condemnation.

16.     ESTOPPEL CERTIFICATES.

                (a) Each Party (as "RESPONDING PARTY") shall within ten (10)
days after written notice from the other Party (the "REQUESTING PARTY") execute,
acknowledge and deliver to the Requesting Party a statement in writing in form
similar to the then most current "ESTOPPEL CERTIFICATE" form published by the
American Industrial Real Estate Association, plus such additional information,
confirmation and/or statements as may be reasonably requested by the Requesting
Party.

                (b) If the Responding Party shall fail to execute or deliver the
Estoppel Certificate within such ten day period, the Requesting Party may
execute an Estoppel Certificate stating that: (i) the 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. Prospective purchasers and encumbrancers may rely upon the
Requesting Party's Estoppel Certificate, and the Responding Party shall be
estopped from denying the truth of the facts contained in said Certificate.

                (c) If Lessor desires to finance, refinance, or sell the
Premises, or any part thereof and Lessee's securities are not then publicly
traded, Lessee and all Guarantors shall deliver to any potential lender or
purchaser designated by Lessor such financial statements as may be reasonably
required by such lender or purchaser, including, but not limited to, Lessee's
financial statements for the past three (3) years. 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.     DEFINITION OF LESSOR. The term "LESSOR" as used herein shall mean the
owner or owners at the time in question of the fee title to the Premises, or, if
this is a sublease, of the Lessee's interest in the prior lease. In the event of
a transfer of Lessor's title or interest in the Premises or this Lease, Lessor
shall deliver to the transferee or assignee (in cash or by credit) any unused
Security Deposit held by Lessor. Except as provided in Paragraph 15, upon such
transfer or assignment and delivery of the Security Deposit, as aforesaid, the
prior Lessor shall be relieved of all liability with respect to the obligations
and/or covenants under this Lease thereafter to be performed by the Lessor.
Subject to the foregoing, the obligations and/or covenants in this Lease to be
performed by the Lessor shall be binding only upon the Lessor as hereinabove
defined. Notwithstanding the above, and subject to the provisions of Paragraph
20 below, the original Lessor under this Lease, and all subsequent holders of
the Lessor's interest in this Lease shall remain liable and responsible with
regard to the potential duties and liabilities of Lessor pertaining to Hazardous
Substances as outlined in Paragraph 6 above.

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

19.     DAYS. Unless otherwise specifically indicated to the contrary, the word
"days" as used in this Lease shall mean and refer to calendar days.

20.     LIMITATION ON LIABILITY. Subject to the provisions of Paragraph 17
above, the obligations of Lessor under this Lease shall not constitute personal
obligations of Lessor, the individual partners of Lessor or its or their
individual partners, directors, officers or shareholders, and Lessee shall look
to the Premises, and to no other assets of Lessor, for the satisfaction of any
liability of Lessor with respect to this Lease, and shall not seek recourse
against the individual partners of Lessor, or its or their individual partners,
directors, officers or shareholders, or any of their personal assets for such
satisfaction.

21.     TIME OF ESSENCE. Time is of the essence with respect to the performance
of all obligations to be performed or observed by the Parties under this Lease.

22.     NO PRIOR OR OTHER AGREEMENTS; BROKER DISCLAIMER. This Lease contains all
agreements between the Parties with respect to any matter mentioned herein, and
no other prior or contemporaneous agreement or understanding shall be effective.
Lessor and Lessee each represents and warrants to the Brokers that it has made,
and is relying solely upon, its own investigation as to the nature, quality,
character and financial responsibility of the other Party to this Lease and as
to the nature, quality and character of the Premises. Brokers have no
responsibility with respect thereto or with respect to any default or breach
hereof by either Party. The liability (including court costs and Attorneys'
fees), of any Broker with respect to negotiation, execution, delivery or
performance by either Lessor or Lessee under this Lease or any amendment or
modification hereto shall be limited to an amount up to the fee received by such
Broker pursuant to this Lease; provided, however, that the foregoing limitation
on each Broker's liability shall not be applicable to any gross negligence or
willful misconduct of such Broker.

23.     NOTICES.

                23.1    NOTICE REQUIREMENTS. All notices required or permitted
by this Lease shall be in writing and may be delivered in person (by hand or by
courier) or shall be sent by certified mail, return receipt requested, or
registered mail, return receipt requested, with postage prepaid, or by facsimile
transmission. The addresses noted adjacent to a Party's signature on this Lease
shall be that Party's address for delivery or mailing of notices. Either Party
may by written notice to the other specify a different address for notice,
except that upon Lessee's taking possession of the

                                 Page 19 of 23
<PAGE>   20
Premises, the Premises shall constitute Lessee's address for notice. A copy of
all notices to Lessor shall be concurrently transmitted to such party or parties
at such addresses as Lessor may from time to time hereafter designate in
writing.

          23.2    DATE OF NOTICE. Any notice sent by registered or certified
mail, return receipt requested, shall constitute receipt of notice on the date
of delivery shown on the receipt card, or if no delivery date is shown, the
postmark thereon. Refusal of receipt by the addressee shall constitute receipt
by the party refusing receipt as of the date delivery was attempted by the means
specified in Paragraph 23.1 or this Paragraph 23.2. Notices delivered by United
States Express Mail or overnight courier that guarantee next day delivery shall
be given upon receipt of the same by the addressee from the Postal Service or
courier. Notices transmitted by facsimile transmission or similar means shall be
given upon telephone confirmation of receipt, provided a copy of the notice is
mailed by the other party by regular mail no later than the next business day.
If notice is received on a Saturday, Sunday or legal holiday, it shall be deemed
received on the next business day.

          23.3 METHOD of TRANSMISSION. All notices, the copy of Lessee's
Hazardous Substances Management Plan (Paragraph 6.5). copies of service
contracts (Paragraph 7.1(b)), evidence of insurance coverages with Lessor named
as an additional insured, (Paragraph 8.2(a)), evidence of payment of taxes
(Paragraph 10.2(a)), documentation relating to proposed assignment of sublease
(Paragraph 12(d)), and any other reports, documentation, or written material
which Lessee is obligated by this Lease to deliver to Lessor shall be
transmitted to Lessor pursuant to the foregoing provisions. Lessor shall use
the same method of transmission of notices and other documentation to Lessee.

24.     WAIVERS. No waiver by either Lessor or Lessee of the Default or
Breach of any term, covenant or condition hereof by the other party, shall be
deemed a waiver of any other term, covenant or condition hereof, or of any
subsequent Default or Breach by the other party of the same or of any other
term, covenant or condition hereof. The consent to, or approval of, any act by
either Lessor or Lessee shall not be deemed to render unnecessary the obtaining
of such party's consent to, or approval of, any subsequent or similar act by the
other party, or be construed as the basis of an estoppel to enforce the
provision or provisions of this Lease requiring such consent. The acceptance of
Rent by Lessor shall not be a waiver of any Default or Breach by Lessee. Any
payment by a party may be accepted by the receiving party on account of monies
or damages due it, notwithstanding any qualifying statements or conditions made
by the paying party in connection therewith, which such statements and/or
conditions shall be of no force or effect whatsoever unless specifically agreed
to in writing by receiving party at or before the time of deposit of such
payment.

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. The Party requesting recordation shall be
responsible for payment of any fees applicable thereto.

26.     NO RIGHT TO HOLDOVER. Lessee has no right to retain possession of the
Premises or any part thereof beyond the expiration or termination of this Lease.
In the event that Lessee holds over, then the Base Rent shall be increased to
one hundred fifty percent (150%) of the Base Rent applicable during the month
immediately preceding the expiration or termination. Nothing contained herein
shall be construed as consent by Lessor to any holding over by Lessee.

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; CONSTRUCTION OF AGREEMENT. All provisions of
this Lease to be observed or performed by Lessee are both covenants and
conditions. In construing this Lease, all headings and titles are for the
convenience of the Parties only and shall not be considered a part of this
Lease. Whenever required by the context, the singular shall include the plural
and vice versa. This Lease shall not be construed as if prepared by one of the
Parties, but rather according to its fair meaning as a whole, as if both Parties
had prepared it.

29.     BINDING EFFECT; CHOICE OF LAW. This Lease shall be binding upon the
parties, their personal representatives, successors and assigns and be governed
by the laws of the State in which the Premises are located. Any litigation
between the Parties hereto concerning this Lease shall be initiated in the
county in which the Premises are located.

30.     SUBORDINATION; ATTORNMENT; NON-DISTURBANCE.

        30.1    SUBORDINATION. This Lease and any Option granted hereby shall be
subject and subordinate to any ground lease, mortgage, deed of trust, or other
hypothecation or security device (collectively, "SECURITY DEVICE"), now or
hereafter placed upon the Premises, to any and all advances made on the

                                 Page 20 of 23
<PAGE>   21
security thereof, and to all renewals, modifications, and extensions thereof.
Lessee agrees that the holders of any such Security Devices (in this Lease
together referred to as "Lessor's Lender") shall have no liability or obligation
to perform any of the obligations of Lessor under this Lease. Any Lender may
elect to have this Lease and/or any Option granted hereby superior to the lien
of its Security Device by giving written notice thereof to Lessee, whereupon
this Lease and such Options shall be deemed prior to such Security Device,
notwithstanding the relative dates of the documentation or recordation thereof.

        30.2    ATTORNMENT. Subject to the non-disturbance provisions of
Paragraph 30.3, Lessee agrees to attorn to a Lender or any other party who
acquires ownership of the Premises by reason of a foreclosure of a Security
Device, and that in the event of such foreclosure, such new owner shall not: (i)
be liable for any act or omission of any prior lessor or with respect to events
occurring prior to acquisition of ownership; (ii) be subject to any offsets or
defenses which Lessee might have against any prior lessor; or (iii) be bound by
prepayment of more than one (1) month's rent.

        30.3    NON-DISTURBANCE. With respect to Security Devices entered into
by Lessor after the execution of this Lease, Lessee's subordination of this
Lease shall be subject to receiving a commercially reasonable non-disturbance
agreement (a "NON-DISTURBANCE AGREEMENT") from the Lender which Non-Disturbance
Agreement provides that Lessee's possession of the Premises, and this Lease,
including any options to extend the term hereof, will not be disturbed so long
as Lessee is not in Breach hereof and attorns to the record owner of the
Premises. Further, within sixty (60) days after the execution of this Lease,
Lessor shall use its commercially reasonable efforts to obtain a Non-Disturbance
Agreement from the holder of any pre-existing Security Device which is secured
by the Premises. In the event that Lessor is unable to provide the
Non-Disturbance Agreement within said sixty (60) days, then Lessee may, at
Lessee's option, directly contact Lessor's lender and attempt to negotiate for
the execution and delivery of a Non-Disturbance Agreement.

        30.4    SELF-EXECUTING. The agreements contained in this Paragraph 30
shall be effective without the execution of any further documents; provided,
however, that, upon written request from Lessor or a Lender in connection with a
sale, financing or refinancing of the Premises, Lessee and Lessor shall execute
such further writings as may be reasonably required to separately document any
subordination, attornment and/or Non-Disturbance Agreement provided for herein.

31.     ATTORNEYS' FEES. If any Party or Broker brings an action or proceeding
involving the Premises to enforce the terms hereof or to declare rights
hereunder, the Prevailing Party (as hereafter defined) in any such proceeding,
action, or appeal thereon, shall be entitled to reasonable attorneys' fees. Such
fees may be awarded in the same suit or recovered in a separate suit, whether or
not such action or proceeding is pursued to decision or judgment. The term,
"PREVAILING PARTY" shall include, without limitation, a Party or Broker who
substantially obtains or defeats the relief sought, as the case may be, whether
by compromise, settlement, judgment, or the abandonment by the other Party or
Broker of its claim or defense. The attorneys' fees award shall not be computed
in accordance with any court fee schedule, but shall be such as to fully
reimburse all attorneys' fees reasonably incurred. In addition, Lessor shall be
entitled to attorneys' fees, costs and expenses incurred in the preparation and
service of notices of Default and consultations in connection therewith, whether
or not a legal action is subsequently commenced in connection with such Default
or resulting Breach.

32.     LESSOR'S ACCESS; SHOWING PREMISES; REPAIRS. Lessor and Lessor's agents
shall have the right to enter the Premises at any time, in the case of an
emergency, and otherwise at reasonable times for the purpose of showing the same
to prospective purchasers, lenders, or lessees, and making such alterations,
repairs, improvements or additions to the Premises as Lessor may deem necessary.
All such activities shall be without abatement of rent or liability to Lessee.
Lessor may at any time place on the Premises any ordinary "FOR SALE" signs and
Lessor may during the last six (6) months of the term hereof place on the
Premises any ordinary "FOR LEASE" signs. Lessee may at any time place on or
about the Premises any ordinary "For Sublease" sign.

33.     AUCTIONS. Lessee shall not conduct, nor permit to be conducted, any
auction upon the Premises without Lessor's prior written consent. Lessor shall
not be obligated to exercise any standard of reasonableness in determining
whether to permit an auction.

34.     SIGNS. Except for ordinary "For Sublease" signs, Lessee shall not place
any sign upon the Premises without Lessor's prior written consent. All signs
must comply with all Applicable Requirements.

35.     TERMINATION; MERGER. Unless specifically stated otherwise in writing by
Lessor, the voluntary or other surrender of this Lease by Lessee, the mutual
termination or cancellation hereof, or a termination hereof by Lessor for Breach
by Lessee, shall automatically terminate any sublease or lesser estate in the
Premises; provided, however, that Lessor may elect to continue any one or all
existing subtenancies. Lessor's failure within ten (10) days following any such
event to elect to the contrary by written notice to the holder of any such
lesser interest, shall constitute Lessor's election to have such event
constitute the termination of such interest.

36.     CONSENTS. Except as otherwise provided herein, wherever in this Lease
the consent of a Party is required to an act by or for the other Party, such
consent shall not be unreasonably withheld or delayed. Lessor's actual
reasonable costs and expenses (including, but not limited to, architects',
attorneys', engineers' and other consultants' fees) incurred in the
consideration of, or response to, a request by Lessee for any Lessor consent,
including, but not limited to, consents to an assignment, a subletting or the
presence or use of a Hazardous Substance, shall be paid by Lessee upon receipt
of an invoice and supporting documentation therefor. Lessor's consent to any
act, assignment or subletting shall not constitute an acknowledgment that no
Default or Breach by Lessee of this Lease exists, nor shall such consent be
deemed a waiver of any then existing Default or Breach, except as may be
otherwise specifically stated in writing by Lessor at the time of such consent.
The failure to specify herein any particular condition to Lessor's consent shall
not preclude the imposition by Lessor at the time of consent of such further or
other conditions as are then reasonable with reference to the particular matter
for which consent is being given. In the event that either Party disagrees with
any determination made by the other hereunder and reasonably requests the
reasons for such determination, the determining party shall furnish its reasons
in writing and in reasonable detail within ten (10) business days following such
request.

38.     QUIET POSSESSION. Subject to payment by Lessee of the Rent and
performance of all of the covenants, conditions and provisions on Lessee's part
to be observed and performed under this Lease, Lessee shall have quiet
possession and quiet enjoyment of the Premises during the term hereof.

                                 Page 21 of 23
<PAGE>   22
41.     SECURITY MEASURES. Lessee hereby acknowledges that the rental payable to
Lessor hereunder does not include the cost of guard service or other security
measures, and that Lessor shall have no obligation whatsoever to provide same.
Lessee assumes all responsibility for the protection of the Premises, Lessee,
its agents and invitees and their property from the acts of third parties.

42.     RESERVATIONS. Lessor reserves to itself the right, from time to time, to
grant, without the consent or joinder of Lessee, such easements, rights and
dedications that Lessor deems necessary, and to cause the recordation of parcel
maps and restrictions, so long as such easements, rights, dedications, maps and
restrictions do not unreasonably interfere with the use of the Premises by
Lessee. Lessee agrees to sign any documents reasonably requested by Lessor to
effectuate any such easement rights, dedication, map or restrictions.

43.     PERFORMANCE UNDER PROTEST. If at any time a dispute shall arise as to
any amount or sum of money to be paid by one Party to the other under the
provisions hereof, the Party against whom the obligation to pay the money is
asserted shall have the right to make payment "under protest" and such payment
shall not be regarded as a voluntary payment and there shall survive the right
on the part of said Party to institute suit for recovery of such sum. If it
shall be adjudged that there was no legal obligation on the part of said Party
to pay such sum or any part thereof, said Party shall be entitled to recover
such sum or so much thereof as it was not legally required to pay.

44.     AUTHORITY. If either Party hereto is a corporation, trust, limited
liability company, partnership, or similar entity, each individual executing
this Lease on behalf of such entity represents and warrants that he or she is
duly authorized to execute and deliver this Lease on its behalf. Each Party
shall, within thirty (30) days after request, deliver to the other Party
satisfactory evidence of such authority.

45.     CONFLICT. Any conflict between the printed provisions of this Lease and
the typewritten or handwritten provisions shall be controlled by the typewritten
or handwritten provisions.

46.     OFFER. Preparation of this Lease by either Party or their agent and
submission of same to the other Party shall not be deemed an offer to lease to
the other Party. This Lease is not intended to be binding until executed and
delivered by all Parties hereto.

47.     AMENDMENTS. This Lease may be modified only in writing, signed by the
Parties in interest at the time of the modification. As long as they do not
materially change Lessee's obligations hereunder, Lessee agrees to make such
reasonable non-monetary modifications to this Lease as may be reasonably
required by a Lender in connection with the obtaining of normal financing or
refinancing of the Premises.

49.     MEDIATION AND ARBITRATION OF DISPUTES. An Addendum requiring the
Mediation and/or the Arbitration of all disputes between the Parties and/or
Brokers arising out of this Lease [ ] IS  [X] IS NOT attached to this Lease.

50.     See Addendum 50.

LESSOR AND LESSEE HAVE CAREFULLY READ AND REVIEWED THIS LEASE AND EACH TERM AND
PROVISION CONTAINED HEREIN, AND BY THE EXECUTION OF THIS LEASE SHOW THEIR
INFORMED AND VOLUNTARY CONSENT THERETO. THE PARTIES HEREBY AGREE THAT, AT THE

AND EFFECTUATE THE INTENT AND PURPOSE OF LESSOR AND LESSEE WITH RESPECT TO THE
PREMISES.

     This AGREEMENT is made effective as of December 6, 1999, by and among

approval of the Board, as evidenced by a resolution of such Board, from time to
time, Executive may serve, or continue to serve, on the boards of directors of,
and hold any other offices or positions in, companies or organizations, which in
such Board's judgment, will not present any conflict of interest with the Bank,
or materially affect the performance of Executive's duties pursuant to this
Agreement.

     (c) Notwithstanding anything herein to the contrary, Executive's employment
with the Bank may be terminated by the Bank or the Executive during the term of
this Agreement, subject to the terms and conditions of this Agreement.

3.   COMPENSATION AND REIMBURSEMENT.

     (a) The Bank shall pay Executive as compensation a salary of One Hundred
Thousand Dollars ($100,000.00) per year ("Base Salary"). Base Salary shall
include any amounts of compensation deferred by Executive under any qualified or
unqualified plan maintained by the Bank. Such Base Salary shall be payable
weekly. During the period of this Agreement, Executive's Base Salary shall be
reviewed at least annually; the first such review will be made no later than one
year from the date of this Agreement. Such review shall be conducted by the
Chief Executive Officer of the Bank. The Chief Executive Officer may increase
Executive's Base Salary. Any increase in Base Salary shall become the "Base
Salary" for purposes of this Agreement. In addition to the Base Salary provided
in this Section 3(a), the Bank shall also provide Executive, at no premium cost
to Executive, with all such other benefits as are provided uniformly to
permanent full-time employees of the Bank, or provided uniformly to senior
executives and key management employees only.

                                       2
<PAGE>   3

     (b) The Executive shall be entitled to participate in or receive benefits
under any employee benefit plans including but not limited to, retirement plans,
supplemental retirement plans, pension plans, profit-sharing plans, health and
accident plans, medical coverage or any other employee benefit plan or
arrangement made available by the Bank in the future to its senior executives
and key management employees, subject to and on a basis consistent with the
terms, conditions and overall administration of such plans and arrangements.
Executive shall be entitled to incentive compensation and bonuses as provided in
any plan of the Bank in which Executive is eligible to participate. Nothing paid
to the Executive under any such plan or arrangement will be deemed to be in lieu
of other compensation to which the Executive is entitled under this Agreement,
nor will it be deemed to be paid in satisfaction of the Base Salary.

     (c) In addition to the Base Salary provided for by paragraph (a) of this
Section 3 and other compensation provided for by paragraph (b) of this Section
3, the Bank shall pay or reimburse Executive for all reasonable travel and other
reasonable expenses incurred by Executive performing his obligations under this
Agreement and may provide such additional compensation in such form and such
amounts as the Board may from time to time determine. The Executive shall be
provided, at his option, with an automobile expense allowance or the use of a
recent model automobile which will be owned or leased by the Bank, as may be
mutually agreed by the Executive and the Bank. All reasonable expenses
associated therewith shall be borne by the Bank.

     (d) In addition to the Base salary and other compensation and reimbursement
set forth in paragraphs (a), (b) and (c) of this Section 3, Executive shall be
paid an annual bonus determined by Executive's achievement of specific goals set
forth by the Board of Directors tied to financial production.

4.   PAYMENTS TO EXECUTIVE UPON AN EVENT OF TERMINATION.

     (a) Upon the occurrence of an Event of Termination (as herein defined)
during the Executive's term of employment under this Agreement, the provisions
of this Section shall apply. As used in this Agreement, an "Event of
Termination" shall mean and include any one or more of the following: (i) the
termination by the Bank of Executive's full-time employment hereunder for any
reason other than a termination governed by Section 5(a) hereof, or Termination
for Cause, as defined in Section 7 hereof; (ii) Executive's resignation from the
Bank's employ upon

                                       3
<PAGE>   4

any (A) failure to elect or reelect or to appoint or reappoint Executive as
Chief Financial Officer, unless consented to by the Executive, (B) a material
change in Executive's function, duties or responsibilities, which change would
cause Executive's position to become one of lesser responsibility, importance or
scope from the position and attributes thereof described in Section 1 above,
unless consented to by Executive, (C) a relocation of Executive's principal
place of employment by more than 20 miles from its location at the effective
date of this Agreement, unless consented to by the Executive, (D) a material
reduction in the benefits and perquisites to the Executive from those being
provided as of the effective date of this Agreement, unless consented to by the
Executive, (E) a liquidation or dissolution of the Bank or Holding Company, or
(F) breach of this Agreement by the Bank, or (iii) the failure or refusal of the
Bank and/or Holding Company to extend this Agreement pursuant to Section 2(a)
above. Upon the occurrence of any event described in clauses (A), (B), (C), (D),
(E) or (F), above, Executive shall have the right to elect to terminate his
employment under this Agreement by resignation upon not less than sixty (60)
days prior written notice given within six (6) full months after the event
giving rise to said right to elect.

     (b) Upon a Event of Termination, Executive shall be entitled to the
benefits provided in Section 5(c) and (d) below, and such benefits shall not be
reduced in the event that Executive obtains other employment following
termination of his employment hereunder.

5.   CHANGE IN CONTROL.

     (a) No benefit shall be payable under this Section 5 unless there shall
have been Change in Control of the Bank or Patriot Bank Corp. (the "Holding
Company"). For purposes of this Agreement, a "Change in Control" of the Bank or
Holding Company shall mean an event of a nature that: (i) would be required to
be reported in response to Item 1 of the current report on Form 8-K, as in
effect on the date hereof, pursuant to Section 13 or 15(d) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"); or (ii) results in a
Change in Control of the Bank or the Holding Company within the meaning of the
Change in Bank Control Act and the Rules and Regulations promulgated by the
Federal Deposit Insurance Corporation ("FDIC") at 12 C.F.R. Section 303.4(a)
with respect to the Bank and the Board of Governors of the Federal Reserve
System ("FRB") at 12 C.F.R. Section 225.41(b) with respect to the Holding
Company, as in effect on the date hereof; or (iii) results in a transaction
requiring prior FRB approval under the Bank Holding Company Act

                                       4
<PAGE>   5

of 1956 and the regulations promulgated thereunder by the FRB at 12 C.F.R.
Section 225.11, as in effect on the date hereof except for the Holding Company's
acquisition of the Bank; or (iv) without limitation such a Change in Control
shall be deemed to have occurred at such time as (A) any "person" (as the term
is used in Sections 13(d) and 14(d) of the Exchange Act) is or becomes the
"beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly
or indirectly, of voting securities of the Bank or the Holding Company
representing 20% or more of the Bank's or the Holding Company's outstanding
voting securities or right to acquire such securities except for any voting
securities of the Bank purchased by the Holding Company and any voting
securities purchased by any employee benefit plan of the Bank or the Holding
Company, or (B) individuals who constitute the Board on the date hereof (the
"Incumbent Board") cease for any reason to constitute at least a majority
thereof, provided that any person becoming a director subsequent to the date
hereof whose election was approved by a vote of at least three-quarters of the
directors comprising the Incumbent Board, or whose nomination for election by
the Holding Company's stockholders was approved by the same Nominating Committee
serving under an Incumbent Board, shall be, for purposes of this clause (B),
considered as though she were a member of the Incumbent Board, (C) a plan of
reorganization, merger, consolidation, sale of all or substantially all the
assets of the Bank or the Holding Company or similar transaction occurs in which
the Bank or Holding Company is not the resulting entity; provided, however, that
such an event listed above will be deemed to have occurred or to have been
effectuated upon the receipt of all required regulatory approvals not including
the lapse of any statutory waiting periods, (D) a proxy statement shall be
distributed soliciting proxies from shareholders of the Holding Company, by
someone other than the current management of the Holding Company, seeking
stockholder approval of a plan of reorganization, merger or consolidation of the
Holding Company or Bank or similar transaction with one or more corporations as
a result of which the outstanding shares of the class of securities then subject
to the plan or transaction are exchanged for or converted into cash or property
or securities not issued by the Bank or the Holding Company, or (E) a tender
offer is made for 20% or more of the voting securities of the Bank or the
Holding Company.

     (b) If a Change in Control has occurred pursuant to Section 5(a) or the
Board has determined that a Change in Control has occurred, Executive shall be
entitled to the benefits provided in paragraphs (c) and (d) of this Section 5
upon his subsequent termination of employment at any time during the term of
this

                                       5
<PAGE>   6

Agreement due to: (1) Executive's dismissal or (2) Executive's voluntary
resignation following any occurrence, under the control of the Bank's or Holding
Company's successor in control, set forth in Section 4(a)(ii)(A) through (F) or
(iii), unless such termination is because of Executive's Termination for Cause.

     (c) Upon Executive's entitlement to benefits pursuant to Section 5(b), the
Bank shall pay Executive, or in the event of his subsequent death, his
beneficiary or beneficiaries, or his estate, as the case may be, a sum equal to
the greater of: (1) the payments due for the remaining term of the Agreement; or
(2) three (3) times Executive's average annual compensation for the five (5)
most recent taxable years that Executive has been employed by the Bank or such
lesser number of years in the event that Executive shall have been employed by
the Bank for less than five (5) years. Such average annual compensation shall
include Base Salary, commissions, bonuses, contributions on Executive's behalf
to any pension and/or profit sharing plan, severance payments, retirement
payments, directors or committee fees, fringe benefits paid or to be paid to the
Executive in any such year and payment of any expense items without
accountability or business purposes or that do not meet the Internal Revenue
Service requirements for deductibility by the Bank. At the election of the
Executive, which election is to be made within thirty (30) days of the Date of
Termination, such payments shall be made in a lump sum or paid in equal monthly
installments during the thirty-six (36) months following the Date of
Termination. In the event that no election is made, payment to the Executive
will be made in approximately equal installments on a monthly basis over a
period of thirty-six (36) months following the Executive's termination. Such
payments shall not be reduced in the event Executive obtains other employment
following termination of employment.

     (d) Upon the executive's entitlement to benefits pursuant to Section 5(b),
the Bank will cause to be continued life, medical, dental and disability
coverage substantially identical to the coverage maintained by the Bank for
Executive prior to his severance at no premium cost to the Executive, except to
the extent that such coverage may be changed in its application for all Bank
employees on a non-discriminatory basis. Such coverage and payments shall cease
upon the expiration of thirty-six (36) months following the Date of Termination.

                                       6
<PAGE>   7

6.   CHANGE OF CONTROL RELATED PROVISIONS.

     Notwithstanding the provisions of Section 5, in no event shall the
aggregate payments or benefits to be made or afforded to Executive under said
paragraphs (the "Termination Benefits") constitute an "excess parachute payment"
under Section 280G of the Code or any successor thereto, and in order to avoid
such a result, Termination Benefits will be reduced, if necessary, to an amount
(the "Non-Triggering Amount"), the value of which is One Dollar ($1.00) less
than an amount equal to three (3) times Executive's "base amount," as determined
in accordance with said Section 280G. The allocation of the reduction required
hereby among the Termination Benefits provided by Section 5 shall be determined
by Executive.

7.   TERMINATION FOR CAUSE.

     (a) The term "Termination for Cause" shall mean termination because of
Executive's personal dishonesty, incompetence, willful misconduct, any breach of
fiduciary duty involving personal profit, intentional failure to perform stated
duties, willful violation of any law, rule or regulation (other than traffic
violations or similar offenses) or final cease-and-desist order or material
breach of any provision of this Agreement. Notwithstanding the foregoing,
Executive shall not be deemed to have been Terminated for Cause unless and until
there shall have been delivered to him a Notice of Termination which shall
include a copy of the resolution duly adopted by the affirmative vote of not
less than a majority of the members of the Board at a meeting of the Board
called and held for that purpose (after reasonable notice to Executive and an
opportunity for him, together with counsel, to be heard before the Board),
finding that in the good-faith opinion of the Board, Executive was guilty of
conduct justifying Termination for Cause and specifying the particulars thereof
in detail. Except as provided in Section 7(b) hereof, Executive shall not have
the right to receive compensation or other benefits for any period after the
Date of Termination. During the period beginning on the date of the Notice of
Termination for Cause pursuant to Section 8 hereof through the Date of
Termination, any stock options and related limited rights granted to Executive
under any stock option plan shall not be exercisable nor shall any unvested
awards granted to Executive under any stock benefit plan of the Bank, the
Holding Company or any subsidiary or affiliate thereof, vest. At the Date of
Termination, such stock options and related limited rights and any such unvested
awards shall become null and void and shall not be exercisable by or delivered
to Executive at any time subsequent to such Termination for Cause.

                                       7
<PAGE>   8

     (b) If, within thirty (30) days after Notice of Termination for Cause is
received by Executive, the Executive notifies the Bank that a dispute exists
concerning the termination ("Notice of Dispute"), the Date of Termination shall
be date on which the dispute is finally determined, either by mutual written
agreement of the parties, by a binding arbitration award, or by a final
judgment, order or decree of a court of competent jurisdiction (the time for
appeal therefrom having expire and no appeal having been perfected) and provided
further that the Date of Termination shall be extended by a Notice of Dispute
only if such notice is given in good faith and the party giving such notice
pursues the resolution of such dispute with reasonable diligence. In the event
the Executive pursues resolution of such dispute through arbitration in
accordance with the rules of the American Arbitration Association then in
effect, the Bank will continue to pay Executive his Base Salary in effect when
the Notice of Dispute notice giving rise to the dispute was given until the
earlier of: (1) the resolution of the dispute pursuant to arbitration in
accordance with this Agreement, or (2) six (6) months from the Date of
Termination as specified in the Notice of Termination for Cause.

8.   NOTICE.

     (a) Any purported termination by the Bank or by Executive shall be
communicated by Notice of Termination to the other party hereto. For purposes of
this Agreement, a "Notice of Termination" shall mean a written notice which
shall indicate the specific termination provision in this Agreement relied upon
and shall set forth in reasonable detail the facts and circumstances claimed to
provide a basis for termination of Executive's employment under the provision so
indicated.

     (b) "Date of Termination" shall mean the date specified in the Notice of
Termination (which, in the case of a Termination for Cause, shall not be less
than thirty (30) days from the date such Notice of Termination is given).

     (c) If, within the thirty (30) days after any Notice of Termination is
given, the party receiving such Notice of Termination notifies the other party
that a dispute exists concerning the termination, the Date of Termination shall
be the date on which the dispute is finally determined, either by mutual written
agreement of the parties, by a binding arbitration award, or by a final
judgment, order or decree of a court of competent jurisdiction (the time for
appeal therefrom having expired and no appeal having been perfected) and
provided further that the Date of Termination shall be extended by a

                                       8
<PAGE>   9

notice of dispute only if such notice is given in good faith and the party
giving such notice pursues the resolution of such dispute with reasonable
diligence. Notwithstanding the pendency of any such dispute, in the event the
Executive is terminated for reasons other than Termination for Cause, which
shall be governed by Section 7 of this Agreement, the Bank will continue to pay
Executive his Base Salary in effect when the notice giving rise to the dispute
was given until the earlier of: (1) the resolution of the dispute in accordance
with this Agreement or (2) the expiration of the remaining term of this
Agreement as determined as of the Date of Termination. Amounts paid under this
Section are in addition to all other amounts due under this Agreement and shall
not be offset against or reduce any other amounts due under this Agreement.

9.   POST-TERMINATION OBLIGATIONS.

     All payments and benefits to Executive under this Agreement shall be
subject to Executive's compliance with this Section 9 for one (1) full year
after the earlier of the expiration of this Agreement or termination of
Executive's employment with the Bank. Executive shall, upon reasonable notice,
furnish such information and assistance to the Bank as may reasonably be
required by the Bank in connection with any litigation in which it or any of its
subsidiaries or affiliates is, or may become, a party.

10.  NONDISCLOSURE OF BANK BUSINESS.

     Executive recognizes and acknowledges that the knowledge of the business
activities and plans for business activities of the Bank and affiliates thereof,
as it may exist from time to time, is a valuable, special and unique asset of
the business of the Bank. Executive will not, during or after the term of his
employment, disclose any knowledge of the past, present, planned or considered
business activities of the Bank or affiliates thereof to any person, firm,
corporation, or other entity for any reason or purpose whatsoever.
Notwithstanding the foregoing, Executive may disclose any knowledge of banking,
financial and/or economic principals, concepts or ideas which are not solely and
exclusively derived from the business plans and activities of the Bank. Further,
Executive may disclose information regarding the business activities of the Bank
to the Federal Deposit Insurance Corporation ("FDIC") pursuant to a formal
regulatory request. In the event of a breach or threatened breach by Executive
of the provisions of this Section, the Bank will be entitled to an injunction
restraining Executive from disclosing, in whole or in part, the knowledge of

                                       9
<PAGE>   10

the past, present, planned or considered business activities of the Bank or
affiliates thereof, or from rendering any services to any person, firm,
corporation, other entity to whom such knowledge, in whole or in part, has been
disclosed or is threatened to be disclosed. Nothing herein will be construed as
prohibiting the Bank from pursuing any other remedies available to the Bank for
such breach or threatened breach, including the recovery of damages from
Executive.

11.  SOURCE OF PAYMENTS.

     All payments provided in this Agreement shall be timely paid in cash or
check from the general funds of the Bank.

12.  EFFECT ON PRIOR AGREEMENTS AND EXISTING BENEFITS PLANS.

     This Agreement contains the entire understanding between the parties hereto
and supersedes any prior employment agreement between the Bank or any
predecessor of the Bank and Executive, except that this Agreement shall not
affect or operate to reduce any benefit or compensation inuring to the Executive
of a kind elsewhere provided. No provision of this Agreement shall be
interpreted to mean that Executive is subject to receiving fewer benefits that
those available to him without reference to this Agreement.

13.  NO ATTACHMENT.

     (a) Except as required by law, no right to receive payments under this
Agreement shall be subject to anticipation, commutation, alienation, sale,
assignment, encumbrance, charge, pledge, or hypothecation, or to execution,
attachment, levy, or similar process or assignment by operation of law, and any
attempt, voluntary or involuntary, to affect any such action shall be null,
void, and of no effect.

     (b) This Agreement shall be binding upon, and inure to the benefit of,
Executive and the Bank and their respective successors and assigns.

14.  MODIFICATION AND WAIVER.

     (a) This Agreement may not be modified or amended except by an instrument
in writing signed by the parties hereto.

     (b) No term or condition of this Agreement shall be deemed to have been
waived, nor shall there be any estoppel against the enforcement of any provision
of this Agreement, except by

                                       10
<PAGE>   11

written instrument of the party charged with such waiver or estoppel. No such
written waiver shall be deemed a continuing waiver unless specifically stated
therein, and each such waiver shall operate only as to the specific term or
condition waived and shall not constitute a waiver of such term or condition for
the future as to any act other than that specifically waived.

15.  LIMITATION ON PAYMENTS.

     Any payments made to Executive pursuant to this Agreement, or otherwise,
are subject to and conditioned upon compliance with 12 U.S.C. Section 1828(k)
and 12 C.F.R. Pt. 359 and any rules and regulations promulgated thereunder.

16.  SEVERABILITY.

     If, for any reason, any provision of this Agreement, or any part of any
provision, is held invalid, such invalidity shall not affect any other provision
of this Agreement or any part of such provision not held so invalid, and each
such other provision and part thereof shall to the full extent consistent with
law continue in full force and effect.

17.  HEADINGS FOR REFERENCE ONLY.

     The headings of sections and paragraphs herein are included solely for
convenience of reference and shall not control the meaning or interpretation of
any of the provisions of this Agreement.

18.  GOVERNING LAW.

     The validity, interpretation, performance and enforcement of this Agreement
shall be governed by the laws of the State of Pennsylvania, but only to the
extent not superseded by federal law.

19.  ARBITRATION.

     Any dispute or controversy arising under or in connection with this
Agreement shall be settled exclusively by arbitration, conducted before a panel
of three arbitrators sitting in a location selected by Executive within fifty
(50) miles from the location of the Bank, in accordance with the rules of the
American Arbitration Association then in effect. Judgment may be entered on the
arbitrator's award in any court having jurisdiction; provided, however, that
Executive shall be entitled to seek specific performance of his right to be paid

                                       11
<PAGE>   12

until the Date of Termination during the pendency of any dispute or controversy
arising under or in connection with this Agreement.

     In the event any dispute or controversy arising under or in connection with
Executive's termination is resolved in favor of Executive, whether by judgment,
arbitration or settlement, Executive shall be entitled to the payment of all
back-pay, including salary, bonuses and any other cash compensation, fringe
benefits and any compensation and benefits due Executive under this Agreement.

20.  PAYMENT OF COSTS AND LEGAL FEES.

     All reasonable costs and legal fees paid or incurred by Executive pursuant
to any dispute or question of interpretation relating to this Agreement shall be
paid or reimbursed by the Bank if Executive is successful on the merits pursuant
to a legal judgment, arbitration or settlement.

21.  INDEMNIFICATION.

     The Bank shall provide Executive (including his heirs, executors and
administrators) with coverage under a standard directors' and officers'
liability insurance policy at its expense, or in lieu thereof, shall indemnify
Executive (and his heirs, executors and administrators) to the fullest extent
permitted under Pennsylvania law against all expenses and liabilities reasonably
incurred by him in connection with or arising out of any action, suit or
proceeding in which he may be involved by reason of his having been a director
or officer of the Bank (whether or not she continues to be a director or officer
at the time of incurring such expenses or liabilities), such expenses and
liabilities to include, but not be limited to, judgements, court costs and
attorneys' fees and the cost of reasonable settlements.

22.  SUCCESSOR TO THE BANK.

     The Bank shall require any successor or assignee, whether direct or
indirect, by purchase, merger, consolidation or otherwise, to all or
substantially all the business or assets of the Bank, expressly and
unconditionally to assume and agree to perform the Bank's obligations under this
Agreement, in the same manner and to the same extent that the Bank would be
required to perform if no such succession or assignment had taken place.
