                       NONSTATUTORY STOCK OPTION AGREEMENT
                 (cliff vesting, performance-based acceleration)

         Pursuant to the Grant Notice and this Nonstatutory Stock Option
Agreement, the Company has granted you an option to purchase the number of
shares of Common Stock indicated in the Grant Notice at the exercise price
indicated in the Grant Notice. Shares issued upon your exercise of your option
are hereinafter referred to as "Option Shares."

         Your option is granted in connection with and in furtherance of the
Company's compensatory benefit plan for the Company's employees (including
officers), directors or consultants, and is intended to comply with the
provisions of Rule 701 promulgated by the Securities and Exchange Commission
under the Securities Act of 1933, as amended (the "Securities Act"). Defined
terms not explicitly defined in this Stock Option Agreement but defined in the
Plan shall have the same definitions as in the Plan.

         The details of your option are as follows:

         1. Vesting. Subject to the limitations contained herein, your option
will vest as provided in the Grant Notice.

         2. Method of Payment.

             (a) Payment Options. Payment of the exercise price by cash or check
is due in full upon exercise of all or any part of your option, provided that
you may elect, to the extent permitted by applicable law and the Grant Notice,
to make payment of the exercise price under one of the following alternatives:

                 (i) Payment pursuant to a program developed under Regulation T
as promulgated by the Federal Reserve Board which, prior to the issuance of
Option Shares, results in either the receipt of cash (or check) by the Company
or the receipt of irrevocable instructions to pay the aggregate exercise price
to the Company from the sales proceeds;

                 (ii) Delivery of shares of any class or series of the Company's
capital stock, the fair market value of which (as determined by the board of
directors of the Company in its sole discretion) is equal to the option exercise
price; or

                 (iii) Payment by a combination of the above methods.

         3. Whole Shares. Your option may only be exercised for whole shares.

         4. Securities Law Compliance. Notwithstanding anything to the contrary
contained herein, your option may not be exercised unless the shares issuable
upon exercise of your option are then registered under the Securities Act or, if
such shares are not then so registered, the Company has determined that such
exercise and issuance would be exempt from the registration requirements of the
Securities Act.

                                       1
<PAGE>
         5. Term. The term of your option commences on the date of grant and
expires upon the earliest of:

            (i) the Expiration Date indicated in the Grant Notice; and

            (ii) the violation by you of any provision of this Agreement.

         6. Exercise.

            (a) You may exercise the your option during its term (to the extent
vested) by delivering a notice of exercise (in a form designated by the Company)
together with the exercise price to the Secretary of the Company, or to such
other person as the Company may designate, during regular business hours,
together with such additional documents as the Company may then require.

            (b) By exercising your option you agree that the Company (or a
representative of the underwriters) may, in connection with the first
underwritten registered public offering of any securities of the Company under
the Securities Act, require that you not sell or otherwise transfer or dispose
of any Option Shares or other securities of the Company during such period (not
to exceed one hundred eighty (180) days) following the effective date of the
registration statement of the Company filed under the Securities Act as may be
requested by the Company or the representative of the underwriters. You further
agree that the Company may impose stop-transfer instructions with respect to
securities subject to the foregoing restrictions until the end of such period.

         7. Transferability. Your option is not transferable, except by will or
by the laws of descent and distribution, and is exercisable during your life
only by you. Notwithstanding the foregoing, by delivering written notice to the
Company, in a form satisfactory to the Company, you may designate a third party
who, in the event of your death, shall thereafter be entitled to exercise your
option.

         8. Right of First Refusal. The Company shall have a right of first
refusal, as set forth below, with respect to the Option Shares. Except for
Permitted Transfers (as defined below), no Option Shares may be transferred
unless (a) the holder delivers to the Company written notice of his/her intent
to transfer all or any part of such shares (the "Offered Shares"), including the
name and address of the proposed transferee and the proposed terms and
conditions of such transfer (the "Notice of Intent to Sell"), and (b) within
thirty (30) days following its receipt of the Notice of Intent to Sell the
Company does not deliver to the holder written notice of its intent to exercise
its right of first refusal and purchase the Offered Shares on the terms set
forth in the Notice of Intent to Sell. The Company's right of first refusal must
be exercised as to all the Offered Shares unless the holder consents to exercise
for less than all the Offered Shares. The purchase of the Offered Shares
following exercise must be completed within sixty (60) days of the Company's
receipt of the Notice of Intent to Sell or such longer period of time as has
been offered by the person to whom you intend to transfer the Offered Shares.
"Permitted Transfer" means a transfer to a member of your immediate family or to
a trust for the benefit of you and/or one or more members of your immediate
family, provided that each such transferee shall have

                                       2
<PAGE>
executed and delivered to the Company a written acknowledgment that such Option
Shares remain subject to the provisions of this Agreement, including the
Company's right of first refusal hereunder. This Section 8 shall terminate and
be of no further force and effect upon the closing of the first underwritten
public offering of the Company's equity securities under the Securities Act.

         9. Taxation; Tax Withholding Requirements. You understand and
acknowledge that upon exercise of your option you will recognize for income tax
purposes an amount of ordinary income equal to the excess, if any, of the fair
market value of the shares of the Common Stock received over the exercise price
for such shares. Any amounts required by any then applicable tax law to be
withheld by the Company from the compensation you are deemed to have received
upon any exercise of your option or portion thereof shall be satisfied, at
election, either by having the Company withhold shares, or by delivery of cash
or shares of the Common Stock having a value equal to the amount required to be
withheld.

         10. Option Not a Service Contract. Your option is not an employment
contract and nothing in your option shall be deemed to create in any way
whatsoever any obligation on your part to continue or resume being in the employ
of the Company, or of the Company to continue or resume your employment with the
Company. In addition, nothing in your option shall obligate the Company, its
shareholders, board of directors, officers or employees to continue or resume
any relationship which you might have as a director or consultant for the
Company.

         11. Notices. Any notices provided for in your option or in the Plan
shall be given in writing and shall be deemed effectively given upon receipt or,
in the case of notices delivered by the Company to you, five (5) days after
deposit in the United States mail, postage prepaid, addressed to you at the last
address you provided to the Company.

         12. Governing Plan Document. Your option is subject to all the
provisions of the Plan, the provisions of which are hereby made a part of your
option, including without limitation the provisions of the Plan relating to
option provisions, and is further subject to all interpretations, amendments,
rules and regulations which may from time to time be promulgated and adopted
pursuant to the Plan. In the event of any conflict between the provisions of
your option and those of the Plan, the provisions of the Plan shall control.

         (e) If after the IPO the average closing price of the Common Stock, as

with respect to the shares referred to in clauses (a), (b), (c) and (d) above,
if not already vested.

         (f) Upon the Sale of the Company (as defined below), vesting shall be
accelerated depending on the Per-Share Equity Value (as defined below) with
respect to the shares set forth below:

<TABLE>

                                                    vested

$6.33 or more but less than $7.27                   the shares referred to in clauses (a) and (b) above, if not
                                                    already vested

$7.27 or more but less than $8.36                   the shares referred to in clauses (a), (b) and (c) above, if
                                                    not already vested

$8.36 or more but less than $9.62                   the shares referred to in clauses (a), (b), (c) and (d) above,
                                                    if not already vested

$9.62 or more                                       the shares referred to in clauses (a), (b), (c), (d) and (e)
                                                    above, if not already vested
</TABLE>

         The vesting of this Option shall be unaffected by the death or
disability of the Optionee.

         This option shall not vest on the Vesting Date or on the date of any
Acceleration Event unless the optionee is an employee of the Company on such
date.

         Example: Assume the Company closes its IPO in January 2003. The stock
does not trade above $5.50 until February 1, 2004 when it increases to $6.00 and
for the next 30 trading days trades between $6.00 and $6.25. Thereafter, the
stock trades below $4.00 until December 1, 2006 when it increases to $10.00 and
closes above $10.00 every trading day in December 2006. Assuming the Optionee
remains employed by the Company, vesting would be as follows: No shares would
vest until the 30 trading days commencing on February 1, 2004 have elapsed after
which 250,000 shares would vest pursuant to clause (a). All of the remaining
shares would vest at the end of December 2006 pursuant to clause (e).

         DEFINITION: As used herein, the following terms shall have the
following respective definitions:
<PAGE>
         "Per-Share Equity Value" means (i) the total amount of cash and the
fair market value of all other property paid directly or indirectly by an
acquiror to the Company and/or its equity security holders in connection with a
Sale of the Company, divided by (ii) the total number of outstanding shares of
the Common Stock immediately before the closing of a Sale of the Company
transaction, assuming the conversion of all shares of capital stock convertible
into the Company and the exercise of all warrants, options and other rights to
purchase the Common Stock. The value of any securities issuable in connection
with a Sale of the Company (whether debt or equity) freely tradable in an
established public market will be determined on the basis of the last closing
price in such market five (5) days prior to the consummation of the Sale of the
Company (the "Valuation Date"), and the value of securities not freely tradable
(or having no established market) or other property will be the fair market
value of such securities or other property on such Valuation Date as determined
in good faith by the Company's Board or Directors.

         "Sale of the Company" means (i) the acquisition by a person, party or a
group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities
Exchange Act of 1934, as amended) of outstanding capital stock of the Company
representing more than 50% of the combined voting power of all voting securities
of the Company entitled to vote generally in the election of directors,
excluding acquisitions from the Company, or (ii) the acquisition of the Company
by means of a reorganization, merger, consolidation, recapitalization or asset
sale, unless the owners of the capital stock of the Company immediately before
such transaction continue to own, in substantially the same proportions as
before such transaction, capital stock of the acquiring or succeeding entity
representing more than 50% of the combined voting power of all voting securities
of such acquiring or succeeding entity entitled to vote generally in the
election of directors.

         ACKNOWLEDGMENT: The undersigned Optionee acknowledges and agrees that
Section 5 of that certain Management Agreement dated as of October 9, 2002 by
and between the Company and the Optionee shall have no effect upon the option
granted hereby and that the terms pursuant to which this option shall vest shall
be governed exclusively by the Nonstatutory Stock Option Agreement to which this
Grant Notice relates.

         ADJUSTMENTS UPON CHANGES IN STOCK: Consistent with Section 10 of the
Plan, in the event of any stock split, stock dividend, reverse stock split,
recapitalization or similar event affecting the Common Stock, the share numbers
and dollar amounts referred to above shall be appropriately adjusted.
<PAGE>
         PAYMENT: Payment by cash or check, or delivery of previously owned
shares of the Common Stock.

provided, promptly after receipt of written notice from Lessee setting forth
with specificity the nature and extent of such non-compliance, rectify the same
at Lessor's expense. If Lessee does not give Lessor written notice of a
non-compliance with warranty within six (6) months following the Start Date,
correction of that non-compliance shall be the obligation of Lessee at Lessee's
sole cost and expense. If the Applicable Requirements are hereafter changed (as
opposed to being in existence at the Start Date, which Is addressed in Paragraph
6.2(e) below) so as to require during the term of this Lease the construction of
an addition to or an alteration of the Building, the remediation of any
Hazardous Substance, or the reinforcement or other physical modification of the
Building ("Capital Expenditure"), Lessor and Lessee shall allocate the cost of
such work as follows:

(1)      provided that Lessee is not in default hereunder, on January 1, 2005,
         the security deposit shall be reduced to $50,875 and any security
         deposit held by Lessor in excess of such amount shall be immediately
         returned to Lessee.

                                                                  Initials WL WB

(a)  Subject to Paragraph 2.3(c) below, if such Capital Expenditures are
     required as a result of the specific and unique use of the Premises by
     Lessee as compared with uses by tenants in general, Lessee shall be fully
     responsible for the cost thereof, provided, however that if such Capital
     Expenditure is required during the last two (2) years of this Lease and the
     cost thereof exceeds six (6) months' Base Rent, Lessee may instead
     terminate this Lease unless Lessor notifies Lessee. in writing, within ten
     (10) days after receipt of Lessee's termination notice that Lessor has
     elected to pay the difference between the actual cost thereof and the
     amount equal to six (6) months' Base Rent. If Lessee elects termination,
     Lessee shall immediately cease the use of the Premises, which requires such
     Capital Expenditure, and deliver to Lessor written notice specifying a
     termination date at least ninety (90) days thereafter. Such termination
     date shall, however. in no event be earlier than the last day that Lessee
     could legally utilize the Premises without commencing such Capital
     Expenditure.

(b)  If such Capital Expenditure is not the result of the specific and unique
     use of the Premises by Lessee (such as, governmentally mandated seismic
     modifications), then Lessor and Lessee shall allocate the obligation to pay
     for such costs pursuant to the provisions of Paragraph 7.1 (c); provided,
     however, that if such Capital Expenditure is required during the last two
     years of this Lease (1), Lessor shall have the option to terminate this
     Lease upon ninety (90) days prior written notice to Lessee unless Lessee
     notifies Lessor, in writing, within ten (10) days after receipt of Lessor's
     termination notice that Lessee will pay (2). If Lessor does not elect to
     terminate, and fails to tender its share of any such Capital Expenditure,
     Lessee may advance such funds and deduct same, with Interest, from Rent
     until Lessor's share of such costs have been fully paid. If Lessee is
     unable to finance Lessor's share, or if the balance of the Rent due and
     payable for the remainder of this Lease is not sufficient to fully
     reimburse Lessee on an offset basis, Lessee shall have the right to
     terminate this Lease upon thirty (30) days written notice to Lessor.

(c)  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, and Lessee shall not have any
     right to terminate this Lease.

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. In
     addition, Lessor acknowledges that: (a) Broker has made no representations,
     promises or warranties concerning Lessee's ability to honor the Lease or
     suitability to occupy the Premises, and (b) it is Lessor's sole
     responsibility to investigate the financial capability and/or suitability
     of all proposed tenants.

2.5. LESSEE AS PRIOR OWNER/OCCUPANT. The warranties made by Lessor in Paragraph
     2 shall be of no force or effect if immediately prior to the Start Date
     Lessee was the owner or occupant of the Premises. In such event, Lessee
     shall be responsible for any necessary corrective work.

3. TERM.

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

3.2. EARLY POSSESSION. If Lessee totally or partially occupies the Premises
     prior to the Commencement Date, the obligation to pay Base Rent shall be
     abated for the period of such early possession. All other terms of this
     Lease (including but not limited to the obligations to pay Real Property
     Taxes and insurance premiums and to maintain the Premises) shall, however,
     be in effect during such period. Any such early possession shall not affect
     the Expiration Date.

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, 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. Should the Agreed Use be
amended to accommodate a material change in the business of Lessee or to
accommodate a sub lessee or assignee, Lessor shall have the right to increase
the Security Deposit to the extent necessary, in Lessor's reasonable judgment,
to account for increased wear and tear that the Premises may suffer as a result
thereof. If a change in control of Lessee occurs during this Lease (3) and
following such change the financial condition of Lessee is, in Lessor's
reasonable judgment, significantly reduced, Lessee shall deposit such additional
monies with Lessor as shall be sufficient to cause the Security Deposit to be at
a commercially reasonable level based on said change in financial condition.
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 LESSOR. If Lessee knows, or has reasonable cause to believe,
     that a Hazardous Substance has come to be located in, on, under or about
     the premises, (in violation of any applicable law) other than as
     previously, other than as previously consented to by Lessor, Lessee shall
     immediately give written notice of such fact to Lessor, and provide Lessor
     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.

(f)  Deleted.

(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,
for the purpose of inspecting the condition of the Premises and for verifying
compliance by Lessee with this Lease (1). The cost of any such inspections shall
be paid by Lessor.

7. MAINTENANCE; REPAIRS, UTILITY INSTALLATIONS; TRADE FIXTURES AND ALTERNATIONS.

7.1. LESSEE'S OBLIGATIONS.

(a)  IN GENERAL. Subject to the provisions of Paragraph 2.2 (Condition), 2.3
     (Compliance), 6.3 (Lessee's Compliance with Applicable Requirements), 7.2
     (Lessor's Obligations). 9 (Damage or Destruction), and 14 (Condemnation),
     Lessee shall, at Lessee's sole expense, keep the Premises, Utility
     Installations, and Alterations in good order, condition and repair (whether
     or not the portion of the Premises requiring repairs, or the means of
     repairing the same, are reasonably or readily accessible to Lessee, and
     whether or not the need for such repairs occurs as a result of Lessee's
     use, any prior use, the elements or the age of such portion of the
     Premises), including, but not limited to, all equipment or facilities, such
     as plumbing, heating, ventilating, air-condition, electrical, lighting
     facilities, boilers, pressure vessels, fire protection system, fixtures,
     walls (interior and exterior), foundations, ceilings, roofs (1), windows,
     doors, plate glass, skylights, landscaping, driveways, parking lots,
     fences, retaining walls, signs, sidewalks and parkways located in, on, or
     adjacent to the Premises. Lessee, in keeping the Premises in good order,
     condition and repair, shall exercise and perform good maintenance
     practices, specifically including the procurement and maintenance of the
     service contracts required by Paragraph 7.1(b) below. Lessee's obligations
     shall include restorations, replacements or renewals when necessary to keep
     the Premises and all improvements thereon or a part thereof in good order,
     condition and state of repair. Lessee shall, during the term of this Lease,
     keep the exterior appearance of the Building in a first-class condition
     consistent with the exterior appearance of other similar facilities of
     comparable age and size in the vicinity, including, when necessary, the
     exterior repainting of the Building.

(b)  SERVICE CONTRACTS. Lessee shall, at Lessee's sole expense, procure and
     maintain contracts, with copies to Lessor, in customary form and substance
     for, and with contractors specializing and experienced in the maintenance
     of the following equipment and improvements ("Basic Elements"), if any, if
     and when installed on the Premises: (i) HVAC equipment, (ii) boiler, and
     pressure vessels, (iii) fire extinguishing systems, including fire alarm
     and/or smoke detection, (iv) landscaping and irrigation systems, (v) roof
     covering and drains, (vi) driveways and parking lots, (vii) clarifiers
     (viii) basic utility feed to the perimeter of the Building, and (ix) any
     other equipment, if reasonably required by Lessor.

(c)  REPLACEMENT. Subject to Lessee's indemnification of Lessor as set forth in
     Paragraph 8.7 below, and without relieving Lessee of liability resulting
     from Lessee's failure to exercise and perform good maintenance practices,
     if the Basic Elements described in Paragraph 7.1 (b) cannot be repaired
     other than at a cost which is in excess of 50% of the cost of replacing
     such Basic Elements, then such Basic Elements shall be replaced by Lessor,
     and the cost thereof shall be prorated between the Parties and Lessee shall
     only be obligated to pay, 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 replacement 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 replacement 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), with
     Lessee reserving the right to prepay its obligation at any time.

7.2. LESSOR'S OBLIGATIONS. Subject to the provisions of Paragraphs 2.2
(Condition), 2.3 (Compliance), 9 (Damage or Destruction) and 14 (Condemnation),
and footnote 1 to Section 7.1 (a), 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 the
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 structural 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

<PAGE>

     Installations to the Premises without Lessor's prior written consent which
     shall not be unreasonably withheld. Lessee may, however, make
     non-structural Utility Installations and Alterations 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 if applicable.

(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,

occurrence with an "ADDITIONAL LNSURED-MANAGERS OR LESSORS OF PREMISES
ENDORSEMENT" and contain the "AMENDMENT OF THE POLLUTION EXCLUSION ENDORSEMENT"

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

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.
If the coverage is available and commercially appropriate, such policy or
policies shall insure against all risks of direct physical loss or damage

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.

     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 ,

     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. The Parties agree to have their respective
     property damage insurance carriers waive any right to subrogation that such
     companies may have against Lessor or Lessee, as the case may be, so long as
     the insurance is not invalidated thereby.

8.7. INDEMNITY. Except for Lessor's gross negligence or willful misconduct,
     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, the cost of which to repair is less than fifty percent (50%) of
the replacement cost of the Premises.

                                     PAGE 5
                                                                  Initials WL WB

<PAGE>

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, the cost of which to repair would exceed fifty percent (50%) of
the replacement cost of the Premises. 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 (ii) 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 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 willful misconduct of Lessee, Lessor shall have the right to recover
     Lessor's damages from Lessee, except as provided in Paragraph 8.6.

<PAGE>

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 thirty (30) 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 a
     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 for which Lessee is not
responsible under this Lease, the Rent and all other charges 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.

     (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,

accepting such assignment or entering into such sublease, be deemed to have
assumed and agreed to conform and comply with each and every term, covenant,
condition and obligation herein to be observed or performed by Lessee during the
term of said assignment or sublease, other than such obligations as are contrary
to or inconsistent with provisions of an assignment or sublease to which Lessor
has specifically consented to in writing.

12.3. ADDITIONAL TERMS AND CONDITIONS APPLICABLE TO SUBLETTING. The following
     terms and conditions shall apply to any subletting by Lessee of all or any
     part OF the Premises and shall be deemed included in all subleases under
     this Lease whether or not expressly incorporated therein:

     (a) Lessee hereby assigns and transfers to Lessor all of Lessee's interest
in all Rent payable on any sublease, and Lessor may collect such Rent and apply
same toward Lessee's obligations under this Lease; provided, however, that until
a Breach shall occur in the performance of Lessee's obligations, Lessee may
collect said Rent. Lessor shall not, by reason of the foregoing or any
assignment of such sublease, nor by reason OF the collection of Rent, be deemed
liable to the sub lessee for any failure of Lessee to perform and comply with
any of Lessee's obligations to such sub lessee. Lessee hereby irrevocably
authorizes and directs any such sub lessee, upon receipt of a written notice

1)   Lessee shall have the right to assign this Lease or to sublet the Premises
     in whole or in part to any entity which controls, is controlled by, or is'
     under common control with Lessee ("Affiliate Lease"), provided that Lessee
     provides written notice to Lessor of any such subletting and of the
     identity of such assignee or sub lessee and provided that the obligation of
     Lessee shall not be diminished or affected in any manner by reason of such
     assignment or subletting. Except for the foregoing,

2)   which consent shall not be unreasonably withheld. Lessor hereby approves a
     sublease (the "Existing Sublease") of approximately 1500 square. feet to
     PCS Building Management.

3)   A sale or transfer of any stock of Lessee shall not constitute a transfer
     or assignment and shall not require the consent of Lessor.

4)   Where Lessor's consent is required hereunder,

5)   Except with respect to the Existing Sublease, in the event that Lessee
     assigns the Lease or sublets an area in excess of thirty percent (30%) of
     the Premises, Lessee shall share with Lessor on a 50-50 basis the amount by
     which the rent or other consideration paid by such assignee or sub lessee
     exceeds the rent payable by Lessee hereunder (determined on a per square
     foot basis after taking into account standard brokerage commissions to
     unaffiliated third parties. Furthermore, in the case of an assignment or
     subletting, Lessor shall have the option to release Lessee from liability
     under this Lease, in which event Lessor shall lease directly to the
     proposed assignee and Lessor shall be entitled to retain all rent without
     any obligation to share any excess rent with Lessee.

                                                                  Initials WL WB

from Lessor stating that a Breach exists in the performance of Lessee's
obligations under this Lease, to pay to Lessor all Rent due and to become due
under the sublease. Sub lessee shall rely upon any such notice from Lessor and
shall pay all Rents to Lessor without any obligation or right to inquire as to
whether such Breach exists, notwithstanding any claim from Lessee to the
contrary.

     (b) In the event of a Breach by Lessee, Lessor may, at its option, require
sub lessee to attorn to Lessor, in which event Lessor shall undertake the
obligations of the sub lessor under such sublease from the time of the exercise
of said option to the expiration of such sublease; provided, however, Lessor
shall not be liable for any prepaid rents or security deposit paid by such sub
lessee to such sub lessor or for any prior Defaults or Breaches of such
sublessor.

     (c) Any matter requiring the consent of the sub lessor under a sublease
shall also require the consent of Lessor.

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

     (e) Lessor shall deliver a copy of any notice of Default or Breach by
Lessee to the sub lessee, who shall have the right to cure the Default of Lessee
within the grace period, if any, specified in such notice. The sub lessee shall
have a right of reimbursement and offset from and against Lessee for any such
Defaults cured by the sub lessee.

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 to fulfill any
obligation under this Lease which endangers or threatens life or property, where
such failure continues for a period of five (5) 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 Estoppel
Certificate, (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. ss. 101 or any successor statute thereto
(unless, in the case of a petition filed against Lessee, the same is dismissed
within sixty (60) days); (iii) the appointment of a trustee or receiver to take
possession of substantially all of Lessee's assets located at the Premises or of
Lessee's Interest in this Lease, where possession is not restored to Lessee
within thirty (30) days; or (iv) the attachment, execution or other judicial
seizure of substantially all of Lessee's assets located at the Premises or of
Lessee's interest in this Lease, where such seizure is not discharged within
thirty (30) days; provided, however, in the event that any provision of this
subparagraph (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.

<PAGE>

     (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
renovation and alteration of 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, 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

                                                                  Initials WL WB

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. Deleted.

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
     amount shall be due, then, without any requirement for notice to Lessee,
     Lessee shall pay to Lessor a one-time late charge equal to five (5%) 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 of Breach with respect
     to such overdue amount, nor prevent the exercise of any of the other rights
     and remedies granted hereunder.

13.5. INTEREST. Any monetary payment due Lessor hereunder, other than late
     charges, not received by Lessor within ten (10) days of 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, 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 cast 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
of the Lessee and Lessee shall be entitled to any and all compensation which is
payable therefor. In the event that this Lease is not terminated by reason of
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, 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 LEASOR. 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 may
     be sent by regular, certified or registered mail or U.S. Postal Service
     Express Mall, with postage prepaid, or by facsimile transmission, and shall
     be deemed sufficiently given if served in a manner specified in this
     Paragraph 23. 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 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.

<PAGE>

23.2. DATE OF NOTICE. Any notice sent by registered or certified mail, return
     receipt requested, shall be deemed given on the date of delivery shown on
     the, receipt card, or if no delivery date is shown, the postmark thereon.
     If sent by regular mail the notice shall be deemed given forty-eight (48)
     hours after the same is addressed as required herein and mailed with
     postage prepaid. Notices delivered by United States Express Mail or
     overnight courier that guarantee next day delivery shall be deemed given
     twenty-four (24) hours after delivery of the same to the Postal Service or

     Saturday, Sunday or legal holiday, it shall be deemed received on the next
     business day.

24. WAIVERS. No waiver by Lessor of the Default or Breach of any term, covenant
or condition hereof by Lessee, shall be deemed a waiver of any other term,
covenant or condition hereof, or of any subsequent Default or Breach by Lessee
of the same or of any other term, covenant or condition hereof. Lessor's consent
to, or approval of, any act shall not be deemed to render unnecessary the
obtaining of Lessor's consent to, or approval of, any subsequent or similar act
by Lessee, 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
Lessee may be accepted by Lessor on account of moneys or damages due Lessor,
notwithstanding any qualifying statements or conditions made by Lessee in
connection therewith, which such statements and/or conditions shall be of no
force or effect whatsoever unless specifically agreed to in writing by Lessor 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 with the consent of Lessor, then the Base
Rent shall be 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
     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 "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,

preclude the imposition by Lessor at the time of consent of such further or

                   ADDENDUM TO STANDARD INDUSTRIAL/COMMERCIAL
                            SINGLE-TENANT LEASE - NET

This Addendum is attached to and forms a part of that certain Standard
Industrial/Commercial Single Tenant Lease - Net by and between LOWENBERG
CORPORATION, a California corporation, as Lessor, and RESEARCH ENGINEERS, INC.,
a California corporation, as Lessee, for the Premises located at 22700 Savi
Ranch Parkway, Yorba Linda, California (the "Lease"). This Addendum modifies and
supplements the Lease by adding the following paragraphs thereto:

1.   BASE RENT ADJUSTMENT. The Base Rent for the Premises shall be adjusted
     every thirty-six (36) months during the initial term to reflect any change
     in the cost of living, the first such adjustment to be effective as of
     January 1, 2003. Each date upon which the Base Rent is to be adjusted is
     hereinafter referred to as an "Adjustment Date". The adjustment, if any,
     shall be calculated upon the basis of the United States Department of
     Labor, Bureau of Labor Statistics Consumer Price Index of Urban Wage
     Earners and Clerical Workers (Revised Series), Subgroup "all items,"
     entitled "Consumer Price Index of Urban Wage Earners and Clerical Workers
     (Revised Series), Los Angeles-Anaheim-Riverside Average, (1982 -1984 =
     100). The Index for said subgroup published for the month prior to the
     Commencement Date or the most recent Adjustment Date, as applicable, shall
     be considered the "base." The then current Base Rent shall be adjusted by
     the percentage increase, if any, in the Index published prior to each
     Adjustment Date for the last month over the "base"; provided, however, that
     in no event shall the Base Rent after such adjustment be less than the Base
     Rent in effect immediately prior to such adjustment, notwithstanding the
     fact that the Index may, as of the adjustment date, be less than the
     "base," and in no event shall the Base Rent after such adjustment exceed
     one hundred nine percent (109%) of the Base Rent in effect immediately
     prior to such adjustment. When the Base Rent is determined, Lessor shall
     give Lessee written notice to that effect indicating how the new Base Rent
     figure was computed. Within fifteen (15) days after Lessor's receipt of
     written request therefor, Lessor shall supply to Lessee such supporting
     documentation for such adjustment as Lessee may reasonably request.

     If at the rental adjustment date there shall not exist the Consumer Price
     Index of Urban Wage Earners and Clerical Workers (Revised Series) in the
     same format as recited in this clause, Lessor shall substitute any official
     index published by the Bureau of Labor Statistics, or successor or similar
     governmental agency, as may then be in existence and shall be most nearly
     equivalent hereto.

2.   EXTENSION OPTIONS.

(a)  Provided Lessee is not in Breach or Default under this Lease, and no event
     or circumstance has occurred which, with th~ giving of notice or the
     passage of time, or both, would constitute a Default or Breach under this
     Lease, Lessee shall have two (2) consecutive options to extend the term of
     this Lease (the "Extension Options") each FOR a five (5) year period (the
     "Extension Terms").
(b)  Each Extension Term shall commence when the Original Terms as previously
     extended, expires. Each Extension Term shall be on all of the same terms
     and conditions as applicable to the Original Term, except FOR the Base
     Rent, which shall be determined as provided herein below.
(c)  Lessee shall exercise an Extension Option, if at all, by delivering to
     Lessor written notice of Lessee's election to exercise such Extension
     Option not less than six

                                      - 1 -

<PAGE>

(6) months prior to expiration of the Original Term, as such term may have been
previously extended.

(d)  Effective as of commencement of each Extension Term (an "FMRR Adjustment
     Date"), the Base Rent then payable under the Lease shall be adjusted to an
     amount equal to the Fair Market Rental Rate of the Premises ("FMRR")
     determined as provided herein below. For purposes of this Lease, FMRR shall
     mean the annual current rent per rentable square foot that a willing lessee
     would pay and a willing lessor would accept, dealing at arm's length, for
     comparable space as the Premises, giving consideration to annual rental
     rates per rentable square foot, improvements, the brokerage commissions, if
     any, which would be paid by a Lessor in a similar transaction, tenant
     improvement allowances typically provided tenants for similar buildings,
     any economic concessions (such as free rent) typically provided to tenants
     in similar type transactions, the quality of construction of the building
     and the Premises and other generally applicable terms and consideration of
     tenancy for the space in question at or about the time that such FMRR is
     deemed to take effect.

(e)  The FMRR and new Base Rent for the Extension Term shall be determined as
     follows:

     (i)  Lessor and Lessee shall attempt to agree upon the FMRR for an
          Extension Term within thirty (30) days after Lessee has exercised an
          Extension Option for an Extension Term.

     (ii) If Lessor and Lessee are unable to agree on the FMRR within such
          thirty (30) day period, then Lessor and Lessee shall, within ten (10)
          days thereafter, attempt to agree upon a mutually acceptable Appraiser
          (as defined herein below) to establish the new FMRR. As used in
          this.Lease, the term "Appraiser" shall mean a real estate broker with
          at least five (5) years' full-time experience in industrial building
          leasing in the geographic area in which the Premises are located. If
          Lessor and Lessee agree on an Appraiser, they shall appoint such
          Appraiser within ten (10) days thereafter, and such sole Appraiser
          shall, within thirty (30) days thereafter, determine the FMRR in
          accordance with this Lease. The cost of the sole Appraiser shall be
          borne equally by Lessor and Lessee.

     (iii) If Lessor and Lessee cannot agree on a mutually acceptable Appraiser
          within said ten (10) day period, then either party may, by giving
          notice to the other party, select and appoint the Appraiser of their
          choice to establish the FMRR. Each party shall bear the cost of the
          Appraiser appointed by it. If either party does not select an
          Appraiser within ten (10) days following receipt of written notice of
          the other party's selection of an Appraiser, then the Appraiser
          appointed by the other party shall be the sole Appraiser and shall,
          within thirty (30) days thereafter, determine the FMRR in aC90rdance
          with this Lease.

     (iv) If two Appraisers are appointed by the parties, then the two
          Appraisers shall attempt, within thirty (30) days after appointment of
          the latter of them, to agree on the determination of the FMRR in
          accordance with this Lease.

     (v)  If the two Appraisers cannot agree on the FMRR within such time
          period, then, within ten (10) days after expiration of such thirty
          (30) day period, then the two Appraisers shall select a third
          Appraiser, who shall have not previously acted in any capacity for
          Lessor, Lessee or either Appraiser. If the two Appraisers are unable
          to agree on the third Appraiser, either Lessor or

                                      - 2 -

<PAGE>

          Lessee, by giving ten (10) days' notice to the other party, can apply
          to the presiding judge of the Superior Court of Orange County, for the
          selection of a third Appraiser. The costs of the third Appraiser shall
          be equally borne by both Lessor and Lessee.

     v.   Within thirty (30) days after the selection of the third Appraiser, a
          majority of the Appraisers shall determine the FMRR. If a majority of
          the Appraisers are unable to agree on the FMRR within such thirty (30)
          day period, the three determinations of the FMRR derived by each
          Appraiser shall be added together and their total divided by three
          (3); the resulting quotient shall be the FMRR; provided, however, that
          if the lowest determination of FMRR and/or the highest determination
          of FMRR are/is more than ten percent (10%) lower and/or higher than
          the middle determination of FMRR, the lowest and/or the highest
          determination of FMRR shall be discarded, and the others averaged
          together to determine the FMRR (or if both the lowest and highest
          determination are both discarded, the middle determination of FMRR
          shall control).

     vi.  Upon the establishment of the FMRR, the new Base Rent under the Lease
          shall be the greater of (1) the FMRR so established, or (ii) the then
          existing Base Rent.
