2.      PREMISES.

        2.1     LETTING. Lessor hereby leases to Lessee, and Lessee hereby
leases from Lessor, the Premises, for the term, at the rental, and upon all of
the terms, covenants and conditions set forth in this Lease. Unless otherwise
provided herein, any statement of size set forth in this Lease, or that may have
been used in calculating rental, is an approximation which the Parties agree is
reasonable and the rental based thereon is not subject to revision whether or
not the actual size is more or less.

        2.2     CONDITION. Except for the construction obligation of Lessor
specified in Lessor's Construction Rider, Lessor shall deliver the Premises to
Lessee broom clean and free of debris on the Commencement Date. The Commencement
Date is also referred to herein as the "Start Date".

        2.3     COMPLIANCE. Lessor warrants that the improvements on the
Premises comply with all applicable laws, covenants or restrictions of record,
building codes, regulations and ordinances ("APPLICABLE REQUIREMENTS") in effect
on the Start Date. Said warranty does not apply to the use to which Lessee will
put the Premises or to any Alterations or Utility Installations (as defined in
Paragraph 7.3(a)) made or to be made by Lessee. NOTE: Lessee is responsible for
determining whether or not the zoning is appropriate for Lessee's intended use,
and acknowledges that past uses of the Premises may no longer be allowed. If the
Premises do not comply with said warranty, Lessor shall, except as otherwise
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 this warranty within twelve (12) 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



                                  PAGE 1 OF 12
<PAGE>   2
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:

               (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 or if Lessor reasonably determines that it is not economically
feasible to pay its share thereof, 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 for such Capital Expenditure or that it
elects to exercise a renewal option pursuant to the Option(s) to Extend. 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.

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.

        3.3     DELAY IN POSSESSION. Lessor agrees to use its best commercially
reasonable efforts to deliver possession of the Premises to Lessee by the
Commencement Date. If, despite said efforts, Lessor is unable to deliver
possession as agreed, Lessor shall not be subject to any liability therefor, nor
shall such failure affect the validity of this Lease. Lessee shall not, however,
be obligated to pay Rent or perform its other obligations until it receives
possession of the Premises. If possession is not delivered within sixty (60)
days after the Commencement Date, Lessee may, at its option, by notice in
writing within ten (10) days after the end of such sixty (60) day period, cancel
this Lease, in which event the Parties shall be discharged from all obligations
hereunder. If such written notice is not received by Lessor within said ten (10)
day period, Lessee's right to cancel shall terminate. Except as otherwise
provided, if possession is not tendered to Lessee by the Start Date and Lessee
does not terminate this Lease, as aforesaid, any period of rent abatement that
Lessee would otherwise have enjoyed shall run from the date of delivery of
possession and continue for a period equal to what Lessee would otherwise have
enjoyed under the terms hereof, but minus any days of delay caused by the acts
or omissions of Lessee.

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

4.      RENT.

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

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

5.      SECURITY DEPOSIT. Lessee shall deposit with Lessor upon execution hereof
the Security Deposit as security for Lessee's faithful performance of its
obligations under this Lease. If Lessee fails to pay Rent, or otherwise Defaults
under this Lease, 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 sublessee or assignee, Lessor shall have the right to increase the
Security Deposit to the extent necessary, in Lessor's reasonable judgment, to
account for any increased wear and tear that the Premises may suffer as a result
thereof. If a change in control of Lessee occurs during this Lease 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



                                  PAGE 2 OF 12
<PAGE>   3

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, 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 BOTH PARTIES FROM ITS OBLIGATIONS UNDER THIS
LEASE WITH RESPECT TO HAZARDOUS SUBSTANCES, UNLESS SPECIFICALLY SO AGREED BY
BOTH PARTIES IN WRITING AT THE TIME OF SUCH AGREEMENT.

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

               (f) INVESTIGATIONS AND REMEDIATIONS. Lessor shall retain the
responsibility and pay for any investigations or remediation measures required
by governmental entities having jurisdiction with respect to the existence of
Hazardous Substances on the Premises prior to the Start Date, unless such
remediation measure is required as a result of Lessee's use (including
"Alterations", as defined in Paragraph 7.3(a) below) of the Premises, in which
event Lessee shall be responsible for such payment. Lessee shall cooperate fully
in any such activities at the request of Lessor, including allowing Lessor and
Lessor's agents to have reasonable access to the Premises at reasonable times in
order to carry out Lessor's investigative and remedial responsibilities.

        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 reasonable recommendations of Lessor's engineers and/or
consultants which relate in any manner to the Premises, without regard to
whether said requirements are now in effect or become effective after the Start
Date. Lessee shall, within ten (10) days after receipt of Lessor's written
request, provide Lessor with copies of all permits and other documents, and
other information evidencing Lessee's compliance with any Applicable
Requirements specified by Lessor, and shall immediately upon receipt, notify
Lessor in writing (with copies of any documents involved) of any threatened or
actual claim, notice, citation, warning, complaint or report pertaining to or
involving the failure of Lessee or the Premises to comply with any Applicable
Requirements.

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

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

        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-conditioning, electrical, lighting facilities, boilers,
pressure vessels, fire protection system, fixtures, walls (interior and
exterior), foundations, ceilings, roofs, floors, windows, doors, plate glass,
skylights, landscaping, driveways, parking lots, fences, retaining walls, signs,
sidewalks and parkways located in, on, or



                                  PAGE 3 OF 12
<PAGE>   4
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, 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. Lessee may use qualified "in-house" personnel in
lieu of third party contracts, subject to Lessor's prior reasonable approval.

               (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 GAAP 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 the Second
Addendum to Lease Paragraphs 2.2 (Condition), 2.3 (Compliance), 9 (Damage or
Destruction) and 14 (Condemnation), it is intended by the Parties hereto that
Lessor have no obligation, in any manner whatsoever, to repair and maintain the
Premises, or the equipment therein, all of which obligations are intended to be
that of the Lessee. It is the intention of the Parties that the terms of this
Lease govern the respective obligations of the Parties as to maintenance and
repair of the Premises, and they expressly waive the benefit of any statute now
or hereafter in effect to the extent it is inconsistent with the terms of this
Lease.

        7.3     UTILITY INSTALLATIONS; TRADE FIXTURES; ALTERATIONS.

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

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

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

        7.4     OWNERSHIP; REMOVAL; SURRENDER; AND RESTORATION.

               (a) OWNERSHIP. Subject to Lessor's right to require removal and
subject to the Second Addendum as hereinafter provided, all Alterations and
Utility Installations made by Lessee shall be the property of Lessee (including,
without limitation, the "Improvements" as defined in the Work Letter Agreement),
but considered a part of the Premises. Unless otherwise instructed per Paragraph
7.4(b) hereof, all Lessee Owned Alterations and Utility Installations shall, at
the expiration or termination of this Lease, become the property of Lessor and
be surrendered by Lessee with the Premises.

               (b) REMOVAL. By delivery to Lessee of written notice from Lessor
not earlier than ninety (90) and not later than thirty (30) days prior to the
end of the term of this Lease, subject to the Second Addendum, Lessor may
require that any or all Lessee Owned Alterations or Utility Installations be
removed by the expiration or termination of this Lease. Lessor may require the
removal at any time of all or any part of any Lessee Owned Alterations or
Utility Installations made without the required consent.

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

8.      INSURANCE; INDEMNITY.

        8.1     PAYMENT FOR INSURANCE. Lessee shall pay for all insurance
required under Paragraph 8 except to the extent of the cost attributable to
liability insurance carried by Lessor under Paragraph 8.2(b) in excess of
$2,000,000 per occurrence. Premiums for policy periods commencing prior to or
extending beyond the Lease term shall be prorated to correspond to the Lease
term. Payment shall be made by Lessee to Lessor within thirty (30) days
following receipt of an invoice.

        8.2     LIABILITY INSURANCE.

                (a) CARRIED BY LESSEE. Lessee shall obtain and keep in force a
Commercial General Liability Policy of Insurance protecting Lessee and Lessor
against claims for bodily injury, personal injury and property damage based upon
or arising out of the ownership, use, occupancy or maintenance of the Premises
and all areas appurtenant thereto. Such insurance shall be on an occurrence
basis providing single limit coverage in an amount not less than $2,000,000 per
occurrence with an "ADDITIONAL INSURED -- MANAGERS OR LESSORS OF PREMISES
ENDORSEMENT" and contain the "AMENDMENT OF THE POLLUTION EXCLUSION ENDORSEMENT"
for damage caused by heat, smoke or fumes from a hostile fire. The Policy shall
not contain any intra-insured exclusions as



                                  PAGE 4 OF 12
<PAGE>   5
between insured persons or organizations, but shall include coverage for
liability assumed under this Lease as an "insured contract" for the performance
of Lessee's indemnity obligations under this Lease. The limits of said insurance
shall not, however, limit the liability of Lessee nor relieve Lessee of any
obligation hereunder. All insurance carried by Lessee shall be primary to and
not contributory with any similar insurance carried by Lessor, whose insurance
shall be considered excess insurance only.

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

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

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

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

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

        8.4     LESSEE'S PROPERTY/BUSINESS INTERRUPTION INSURANCE.

                (a) PROPERTY DAMAGE. Lessee shall obtain and maintain insurance
coverage on all of Lessee's personal property, Trade Fixtures, and Lessee Owned
Alterations and Utility Installations. Such insurance shall be full replacement
cost coverage with a deductible of not to exceed $10,000.00 per occurrence. The
proceeds from any such insurance shall be used by Lessee at Lessee's option for
the replacement of personal property, Trade Fixtures and Lessee Owned
Alterations and Utility Installations. Lessee shall provide Lessor with written
evidence that such insurance is in force.

                (b) BUSINESS INTERRUPTION. Lessee shall obtain and maintain loss
of income and extra expense insurance in amounts as will reimburse Lessee for
direct or indirect loss of earnings attributable to all perils commonly insured
against by prudent lessees in the business of Lessee or attributable to
prevention of access to the Premises as a result of such perils.

                (c) NO REPRESENTATION OF ADEQUATE COVERAGE. Lessor makes no
representation that the limits or forms of coverage of insurance specified
herein are adequate to cover Lessee's property, business operations or
obligations under this Lease.

        8.5     INSURANCE POLICIES. Insurance required herein shall be by
companies duly licensed or admitted to transact business in the state where the
Premises are located, and maintaining during the policy term a "General
Policyholders Rating" of at least B+, V, as set forth in the most current issue
of "Best's Insurance Guide", or such other rating as may be required by a
Lender. Lessee shall not do or permit to be done anything which invalidates the
required insurance policies. Lessee shall, prior to the Start Date, deliver to
Lessor certified copies of policies of such insurance or certificates evidencing
the existence and amounts of the required insurance. No such policy shall be
cancelable or subject to modification except after thirty (30) days prior
written notice to Lessor. Lessee shall, at least thirty (30) days prior to the
expiration of such policies, furnish Lessor with evidence of renewals or
"insurance binders" evidencing renewal thereof, or Lessor may order such
insurance and charge the cost thereof to Lessee, which amount shall be payable
by Lessee to Lessor upon demand. Such policies shall be for a term of at least
one year, or the length of the remaining term of this Lease, whichever is less.
If either Party shall fail to procure and maintain the insurance required to be
carried by it, the other Party may, but shall not be required to, procure and
maintain the same.

        8.6     WAIVER OF SUBROGATION. Without affecting any other rights or
remedies, Lessee and Lessor each hereby release and relieve the other, and waive
their entire right to recover damages against the other, for loss of or damage
to its property arising out of or incident to the perils required to be insured
against herein. The effect of such releases and waivers is not limited by the
amount of insurance carried or required, or by any deductibles applicable
hereto. 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 negligence,
willful misconduct or breach of the Lease by Lessee. If any action or proceeding
is brought against Lessor by reason of any of the foregoing matters, Lessee
shall upon notice defend the same at Lessee's expense by counsel reasonably
satisfactory to Lessor and Lessor shall cooperate with Lessee in such defense.
Lessor need not have first paid any such claim in order to be defended or
indemnified.

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

9.      DAMAGE OR DESTRUCTION.

        9.1     DEFINITIONS.

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

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

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

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

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

        9.2     PARTIAL DAMAGE -- INSURED LOSS. If a Premises Partial Damage
that is an Insured Loss occurs, then Lessor shall, at Lessor's expense, repair
such damage (but not Lessee's Trade Fixtures or Lessee Owned Alterations and
Utility Installations) as soon as reasonably possible and this Lease



                                  PAGE 5 OF 12
<PAGE>   6
shall continue in full force and effect; provided, however, that Lessee shall,
at Lessor's election, make the repair of any damage or destruction the total
cost to repair of which is $10,000 or less, and, in such event, Lessor shall
make any applicable insurance proceeds available to Lessee on a reasonable basis
for that purpose. Notwithstanding the foregoing, if the required insurance was
not in force or the insurance proceeds are not sufficient to effect such repair,
the Insuring Party shall promptly contribute the shortage in proceeds (except as
to the deductible which is Lessee's responsibility) as and when required to
complete said repairs. In the event, however, such shortage was due to the fact
that, by reason of the unique nature of the improvements, full replacement cost
insurance coverage was not commercially reasonable and available, Lessor shall
have no obligation to pay for the shortage in insurance proceeds or to fully
restore the unique aspects of the Premises unless Lessee provides Lessor with
the funds to cover same, or adequate assurance thereof, within ten (10) days
following receipt of written notice of such shortage and request therefor. If
Lessor receives said funds or adequate assurance thereof within said ten (10)
day period, the party responsible for making the repairs shall complete them as
soon as reasonably possible and this Lease shall remain in full force and
effect. If such funds or assurance are not received, Lessor may nevertheless
elect by written notice to Lessee within ten (10) days thereafter to: (i) make
such restoration and repair as is commercially reasonable with Lessor paying any
shortage in proceeds, in which case this Lease shall remain in full force and
effect, or have this Lease terminate thirty (30) days thereafter. Lessee shall
not be entitled to reimbursement of any funds contributed by Lessee to repair
any such damage or destruction. Premises Partial Damage due to flood or
earthquake shall be subject to Paragraph 9.3, notwithstanding that there may be
some insurance coverage, but the net proceeds of any such insurance shall be
made available for the repairs if made by either Party.

        9.3     PARTIAL DAMAGE -- UNINSURED LOSS. If a Premises Partial Damage
that is not an Insured Loss occurs, unless caused by a negligent or willful act
of Lessee (in which event Lessee shall make the repairs at Lessee's expense),
Lessor may either: (i) repair such damage as soon as reasonably possible at
Lessor's expense, in which event this Lease shall continue in full force and
effect, or (ii) terminate this Lease by giving written notice to Lessee within
thirty (30) days after receipt by Lessor of knowledge of the occurrence of such
damage. Such termination shall be effective sixty (60) days following the date
of such notice. In the event Lessor elects to terminate this Lease, Lessee shall
have the right within ten (10) days after receipt of the termination notice to
give written notice to Lessor of Lessee's commitment to pay for the repair of
such damage without reimbursement from Lessor. Lessee shall provide Lessor with
said funds or satisfactory assurance thereof within thirty (30) days after
making such commitment. In such event this Lease shall continue in full force
and effect, and Lessor shall proceed to make such repairs as soon as reasonably
possible after the required funds are available. If Lessee does not make the
required commitment, this Lease shall terminate as of the date specified in the
termination notice.

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

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

        9.6     ABATEMENT OF RENT; LESSEE'S REMEDIES.

                (a) ABATEMENT. In the event of Premises Partial Damage or
Premises Total Destruction or a Hazardous Substance Condition for which Lessee
is not responsible under this Lease, the Rent payable by Lessee for the period
required for the repair, remediation or restoration of such damage shall be
abated in proportion to the degree to which Lessee's use of the Premises is
impaired, but not to exceed the proceeds received from the Rental Value
insurance. All other obligations of Lessee hereunder shall be performed by
Lessee, and Lessor shall have no liability for any such damage, destruction,
remediation, repair or restoration except as provided herein.

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

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

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

10.     REAL PROPERTY TAXES.

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

        10.2

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

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

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

        10.4    PERSONAL PROPERTY TAXES. Lessee shall pay, prior to delinquency,
all taxes assessed against and levied upon Lessee Owned Alterations, Utility
Installations, Trade Fixtures, furnishings, equipment and all personal property
of Lessee. When possible, Lessee shall cause such property to be



                                  PAGE 6 OF 12
<PAGE>   7
assessed and billed separately from the real property of Lessor. If any of
Lessee's said personal property shall be assessed with Lessor's real property,
Lessee shall pay Lessor the taxes attributable to Lessee's property within ten
(10) days after receipt of a written statement.

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

12.     ASSIGNMENT AND SUBLETTING.

        12.1    LESSOR'S CONSENT REQUIRED.

                (a) Lessee shall not voluntarily or by operation of law assign,
transfer, mortgage or encumber (collectively, "ASSIGN OR ASSIGNMENT") or sublet
all or any part of Lessee's interest in this Lease or in the Premises without
Lessor's prior written consent.

                (c) "NET WORTH OF LESSEE" shall mean the net worth of Lessee
(excluding any guarantors) established under generally accepted accounting
principles.

                (d) An assignment or subletting without consent shall, at
Lessor's option, be a Default curable after notice per Paragraph 13.1(c), or a
noncurable Breach without the necessity of any notice and grace period. If
Lessor elects to treat such unapproved assignment or subletting as a noncurable
Breach, Lessor may either: (i) terminate this Lease, or (ii) upon thirty (30)
days written notice, increase the monthly Base Rent to one hundred ten percent
(110%) of the Base Rent then in effect. Further, in the event of such Breach and
rental adjustment, (i) the purchase price of any option to purchase the Premises
held by Lessee shall be subject to similar adjustment to one hundred ten percent
(110%) of the price previously in effect, and (ii) all fixed and non-fixed
rental adjustments scheduled during the remainder of the Lease term shall be
increased to One Hundred Ten Percent (110%) of the scheduled adjusted rent.

                (e) Lessee's remedy for any breach of Paragraph 12.1 by Lessor
shall be limited to compensatory damages and/or injunctive relief.

        12.2    TERMS AND CONDITIONS APPLICABLE TO ASSIGNMENT AND SUBLETTING.

                (a) Regardless of Lessor's consent, any assignment or subletting
shall not: (i) be effective without the express written assumption by such
assignee or sublessee of the obligations of Lessee under this Lease; (ii)
release Lessee of any obligations hereunder; or (iii) alter the primary
liability of Lessee for the payment of Rent or for the performance of any other
obligations to be performed by Lessee.

                (b) Lessor may accept Rent or performance of Lessee's
obligations from any person other than Lessee pending approval or disapproval of
an assignment. Neither a delay in the approval or disapproval of such assignment
nor the acceptance of Rent or performance shall constitute a waiver or estoppel
of Lessor's right to exercise its remedies for Lessee's Default or Breach.

                (c) Lessor's consent to any assignment or subletting shall not
constitute a consent to any subsequent assignment or subletting.

                (d) In the event of any Default or Breach by Lessee, Lessor may
proceed directly against Lessee, any Guarantors or anyone else responsible for
the performance of Lessee's obligations under this Lease, including any assignee
or sublessee, without first exhausting Lessor's remedies against any other
person or entity responsible therefore to Lessor, or any security held by
Lessor.

                (e) Each request for consent to an assignment or subletting
shall be in writing, accompanied by information relevant to Lessor's
determination as to the financial and operational responsibility and
appropriateness of the proposed assignee or sublessee, including but not limited
to the intended use and/or required modification of the Premises, if any,
together with a fee of $1,000, as consideration for Lessor's considering and
processing said request. Lessee agrees to provide Lessor with such other or
additional information and/or documentation as may be reasonably requested.

                (f) Any assignee of, or sublessee under, this Lease shall, by
reason of 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 sublessee for any failure of Lessee to perform and
comply with any of Lessee's obligations to such sublessee. Lessee hereby
irrevocably authorizes and directs any such sublessee, upon receipt of a written
notice 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. Sublessee 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 sublessee to attorn to Lessor, in which event Lessor shall
undertake the obligations of the sublessor 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 sublessee to such sublessor or for any prior Defaults or Breaches
of such sublessor.

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

                (d) No sublessee 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 sublessee, who shall have the right to cure the Default
of Lessee within the grace period, if any, specified in such notice. The
sublessee shall have a right of reimbursement and offset from and against Lessee
for any such Defaults cured by the sublessee.

13.     DEFAULT; BREACH; REMEDIES.

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

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

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

                (c) The failure by Lessee to provide (i) reasonable written
evidence of compliance with Applicable Requirements (or, if compliance cannot
reasonably be achieved within such ten (10) day period, that Lessee is
diligently pursuing such compliance), (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




                                  PAGE 7 OF 12
<PAGE>   8
deemed to be a Breach if Lessee commences such cure within said thirty (30) day
period and thereafter diligently prosecutes such cure to completion.

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

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

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

        13.2    REMEDIES. If Lessee fails to perform any of its affirmative
duties or obligations, within the time periods set forth above (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 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.

        13.4    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 percent (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 or Breach with respect to such overdue amount, nor
prevent the exercise of any of the other rights and remedies granted hereunder.
In the event that a late charge is payable hereunder, whether or not collected,
for three (3) consecutive installments of Base Rent, then notwithstanding any
provision of this Lease to the contrary, Base Rent shall, at Lessor's option,
become due and payable quarterly in advance.

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

        13.6    BREACH BY LESSOR.

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

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

14.     CONDEMNATION. If the Premises or any portion thereof are taken under the
power of eminent domain or sold under the threat of the exercise of said power
(collectively "CONDEMNATION"), this Lease shall terminate as to the part taken
as of the date the condemning authority takes title or possession, whichever
first occurs. If more than ten percent (10%) of any building portion of the
Premises, or more than twenty-five percent (25%) of the land area portion of the
Premises not occupied by any building, is taken by Condemnation, Lessee may, at
Lessee's option, to be exercised in writing within ten (10) days after



                                  PAGE 8 OF 12
<PAGE>   9
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.

15.     BROKERS' FEE.

        15.1    ADDITIONAL COMMISSION. In addition to the payments owed pursuant
to Paragraph 1.10 above, and unless Lessor and the Brokers otherwise agree in
writing, Lessor agrees that: (a) if Lessee exercises any Option, (b) if Lessee
acquires any rights to the Premises or other premises owned by Lessor and
located within the same Project, if any, within which the Premises is located,
(c) if Lessee remains in possession of the Premises, with the consent of Lessor,
after the expiration of this Lease, or (d) if Base Rent is increased, whether by
agreement or operation of an escalation clause herein, then, Lessor shall pay
Brokers a fee in accordance with the schedule of said Brokers in effect at the
time of the execution of this Lease.

        15.2    ASSUMPTION OF OBLIGATIONS. Any buyer or transferee of Lessor's
interest in this Lease shall be deemed to have assumed Lessor's obligation
hereunder. Each Broker shall be a third party beneficiary of the provisions of
Paragraphs 1.10, 15, 22 and 31. If Lessor fails to pay to a Broker any amounts
due as and for commissions pertaining to this Lease when due, then such amounts
shall accrue Interest. In addition, if Lessor fails to pay any amounts to
Lessee's Broker when due, Lessee's Broker may send written notice to Lessor and
Lessee of such failure and if Lessor fails to pay such amounts within ten (10)
days after said notice, Lessee shall pay said monies to its Broker and offset
such amounts against Rent. In addition, Lessee's Broker shall be deemed to be a
third party beneficiary of any commission agreement entered into by and/or
between Lessor and Lessor's Broker.

        15.3    REPRESENTATIONS AND INDEMNITIES OF BROKER RELATIONSHIPS. Lessee
and Lessor each represent and warrant to the other that it has had no dealings
with any person, firm, broker or finder (other than the Brokers, if any) in
connection with this Lease, and that no one other than said named Brokers is
entitled to any commission or finder's fee in connection herewith. Lessee and
Lessor do each hereby agree to indemnify, protect, defend and hold the other
harmless from and against liability for compensation or charges which may be
claimed by any such unnamed broker, finder or other similar party by reason of
any dealings or actions of the indemnifying Party, including any costs,
expenses, and/or attorneys' fees reasonably incurred with respect thereto.

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 LESSOR. The term "LESSOR" as used herein shall mean the
owner or owners at the time in question of the fee title to the Premises, or, if
this is a sublease, of the Lessee's interest in the prior lease. In the event of
a transfer of Lessor's title or interest in the Premises or this Lease, Lessor
shall deliver to the transferee or assignee (in cash or by credit) any unused
Security Deposit held by Lessor. Except as provided in Paragraph 15, upon such
transfer or assignment and delivery of the Security Deposit, as aforesaid, and
the written assumption by Transferree of Lessor's obligations hereunder, 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 Mail, 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.

                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 when
actually received. Notices delivered by United States Express Mail or overnight
courier that guarantee next day delivery shall be deemed given one (1) business
day after delivery of the same to the Postal Service or courier. Notices
transmitted by facsimile transmission or similar means shall be deemed delivered
upon telephone confirmation of receipt, provided a copy is also delivered via
delivery or mail. If notice is received on a Saturday, Sunday or legal holiday,
it shall be deemed received on the next business day.

24.     WAIVERS. No waiver by the other party of the Default or Breach of any
term, covenant or condition hereof by either party,



                                  PAGE 9 OF 12
<PAGE>   10
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 monies 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, then the Base Rent shall be increased to
one hundred fifty percent (150%) of the Base Rent applicable during the month
immediately preceding the expiration or termination. Nothing contained herein
shall be construed as consent by Lessor to any holding over by Lessee.

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

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

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

30.     SUBORDINATION; ATTORNMENT; NON-DISTURBANCE.

        30.1    SUBORDINATION. This Lease and any Option granted hereby shall be
subject and subordinate to any ground lease, mortgage, deed of trust, or other
hypothecation or security device (collectively, "SECURITY DEVICE"), now or
hereafter placed upon the Premises, to any and all advances made on the security
thereof, and to all renewals, modifications, and extensions thereof. Lessee
agrees that the holders of any such Security Devices (in this Lease together
referred to as "Lessor's Lender") shall have no liability or obligation to
perform any of the obligations of Lessor under this Lease. Any Lender may elect
to have this Lease and/or any Option granted hereby superior to the lien of its
Security Device by giving written notice thereof to Lessee, whereupon this Lease
and such Options shall be deemed prior to such Security Device, notwithstanding
the relative dates of the documentation or recordation thereof.

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

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

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

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

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

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

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

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

36.     CONSENTS. Except as otherwise provided herein, wherever in this Lease
the consent of a Party is required to an act by or for the other Party, such
consent shall not be unreasonably withheld or delayed. Lessor's actual
reasonable costs and expenses (including, but not limited to, architects',
attorneys', engineers' and other consultants' fees) incurred in the
consideration of, or response to, a request by Lessee for any Lessor consent,
including, but not limited to, consents to an assignment, a subletting or the
presence or use of a Hazardous Substance, (not to exceed $1,000.00 per request
for consent) shall be paid by Lessee upon receipt of an invoice and supporting
documentation therefor. Lessor's consent to any act, assignment or subletting
shall not constitute an acknowledgment that no Default or Breach by Lessee of
this Lease exists, nor shall such consent be deemed a waiver of any then
existing Default or Breach, except as may be otherwise specifically stated in
writing by Lessor at the time of such consent. The failure to specify herein any
particular condition to Lessor's consent shall not preclude the imposition by
Lessor at the time of consent of such further or other conditions as are then
reasonable with reference to the particular matter for which consent is being
given. In the event that either Party disagrees with any determination made by
the other hereunder and reasonably requests the reasons for such determination,
the determining party shall furnish its reasons in writing and in reasonable
detail within ten (10) business days following such request.

the prior Options have been validly exercised.

        39.4    EFFECT OF DEFAULT ON OPTIONS.

                (a) Lessee shall have no right to exercise an Option: (i) during
the period commencing with the giving of any notice of Default and continuing
until said Default is cured, (ii) during the period of time any Rent is unpaid
(without regard to whether notice thereof is given Lessee), (iii) during the
time Lessee is in Breach of this Lease, or (iv) in the event that Lessee has
been given three (3) or more notices of separate Default, whether or not the
Defaults are cured, during the twelve (12) month period immediately preceding
the exercise of the Option.

                (b) The period of time within which an Option may be exercised
shall not be extended or enlarged by reason of Lessee's inability to exercise an
Option because of the provisions of Paragraph 39.4(a).

                (c) An Option shall terminate and be of no further force or
effect, notwithstanding Lessee's due and timely exercise of the Option, if,

Lessee fails to pay Rent for a period of thirty (30) days after such Rent
becomes due (without any necessity of Lessor to give notice thereof), (ii)
Lessor gives to Lessee three (3) or more notices of separate Default during any

grounds and including the parking, loading and unloading of vehicles, and that
Lessee will pay its fair share of common expenses incurred in connection
therewith.

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

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

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

44.     AUTHORITY. If either Party hereto is a corporation, trust, limited
liability company, partnership, or similar entity, each individual executing
this Lease on behalf of such entity represents and warrants that he or she is
duly authorized to execute and deliver this Lease on its behalf. Each Party

reasonable non-monetary modifications to this Lease as may be reasonably
required by a Lender in connection with the obtaining of normal financing or
refinancing of the Premises.

48.     MULTIPLE PARTIES. If more than one person or entity is named herein as

PREMISES

2.6     RIGHT OF FIRST OFFER-BUILDING PURCHASE:

        In the event that Lessor intends to sell the building, Lessee shall have
        a Right of First Offer to Purchase the building at the price and terms
        Lessor is willing to accept from a third party.

        If Lessor wishes to sell the Premises during the Term, it shall give
        written notice to Lessee of the price and relevant terms that Lessor
        will accept for the Premises. Lessee shall have ten (10) business days
        to give Lessor written notice that it accepts such price and terms, and
        such notice shall constitute unequivocal acceptance of all terms and
        conditions in Lessor's notice. Failure to give such notice shall
        constitute a rejection of the terms in Lessor's notice and a waiver of
        any right to purchase the Premises, subject to the following paragraph.

        If Lessee does not elect to purchase the Premises pursuant to the
        preceding paragraph, Lessor may, for a period of six (6) months, enter
        into a written agreement to sell the Premises on terms and conditions
        not materially less favorable to Lessor than those in Lessor's notice to
        Lessee. If it does not enter into such an agreement, and thereafter sell
        the Premises in accordance therewith, then it shall not subsequently
        offer the Premises for sale without again giving Lessee notice as set
        forth in the previous paragraph.

4.3     ADDITIONAL RENT:

        Charges for real estate taxes and insurance will be dependent upon the
        improvements Lessee places in the Building as determined by the Ventura
        County Assessor's Office. Common area fees are limited to quarterly dues
        payable to the Mission Oaks Business Park Owner's Association. These
        fees amount to approximately $1,800.00 annually. A management fee of
        1.5% (See LOI-Lessor is not providing services) of the monthly rent
        will be charged by Lessor. All services and other charges payable
        by Lessee would be billed to Lessee at their actual cost.

7.3(b)  ADDITIONAL PARKING:
        SITE DESCRIPTION:

        Basic Site:          306,824 sq. ft. 284 parking
        Expanded Site:       354,817 sq. ft. 427 parking
        Thus, approximately 47,993 sq. ft. will need to be improved.

        Lessee, at Lessee's sole cost, shall be responsible for the cost of
        improving the additional parking area at the time this additional
        parking is needed.

7.3(e)  TENANT IMPROVEMENTS:

        and omissions, liability, and workman's comp. to Lessor for any

        transfer of title of the Property for the first five (5) years of the
        Lease.

regarding present and future zoning and environmental matters affecting the
Property and regarding the condition of the Property including, but not limited
to, structural, mechanical and soils conditions, the presence and location of
asbestos, PCB transformers, other toxic, hazardous or contaminated substances,
and underground storage tanks, in, on, or about the Property.

ADA:

Lessee acknowledges that it has examined the relevant provisions of the
Americans With Disabilities Act (the ADA), a Federal law codified at 42 USC
Section 12101 et seq. and satisfied itself with respect to the ADA's impact on
the Premises and Lessee's planned development thereof.

        This Work Letter Agreement ("Agreement") is entered into by and between
PEGH Investments, LLC ("Lessor") and New Focus, Inc. ("Lessee"). Concurrently
with the execution of this Agreement, Lessor and Lessee have entered into a
Standard Industrial/Commercial Single-Lessee Lease - Net of even date herewith
(the "Lease") covering certain premises (the "Premises") more particularly
described in Section 1.2 of the Lease.

        1.      Base Building

               Except as otherwise provided herein, Lessor and Lessee
acknowledge that this Agreement relates only to construction work by Lessee in
the Premises. The parties acknowledge that, SUBJECT TO THE TERM OF THE LEASE,
the Premises are currently vacant, and will be delivered in an "as is"
condition; any leasehold improvements required by Lessee will be constructed by
Lessee, according to the terms hereof. Any demolition work required by Lessee in
connection with the construction of the Improvements (as hereinafter defined)
shall be Lessee's responsibility. All existing improvements (if any, including
any building systems located within the Premises) shall be provided to Lessee as
part of the Premises.

        2.      Plans and Specifications

               (a) Lessee's Design Professionals. Prior to commencement of
design, Lessee shall submit to Lessor for approval the names of the architects
and design professionals which Lessee intends to use for preparing the necessary
plans and specifications, which approval shall not be unreasonably withheld,
conditioned or delayed. Notwithstanding the foregoing, Lessee shall be required
to utilize the services of mechanical, electrical, plumbing, roof, fire
sprinkler, and structural engineers designated by Lessor and reasonably
acceptable to Lessee, provided such engineers are competitively priced. The cost
of Lessee's architects, engineers and design professionals shall be borne solely
by Lessee.

               (b) Space Plan. Lessee shall submit to Lessor for approval as set
forth herein a detailed space plan ("Space Plan") for the Premises prepared by
Lessee's architects and consultants, which shall include without limitation, the
location of doors, partitions, electrical and telephone outlets, plumbing
fixtures, heavy floor loads and other special requirements. Within ten (10)
business days after receipt by Lessor of the Space Plan, Lessor (i) shall give
its written approval with respect thereto, or (ii) shall notify Lessee in
writing of its disapproval and state with specificity the grounds for such
disapproval and the revisions or modifications necessary in order for Lessor to
give its approval. Within five (5) business days following receipt by Lessor of
such revisions or modifications, Lessor shall give its written approval with
respect thereto or shall request other revisions or modifications therein (but
relating only to the extent Lessee has failed to comply with Lessor's earlier
reasonable requests). The preceding sentence shall be implemented repeatedly
until Lessor gives its approval to Lessee's Space Plan.


                (c) Plans. Based on the approved Space Plan, Lessee shall cause
its architects and engineers to prepare and submit to Lessor for approval
detailed plans, specifications and working drawings ("Plans") for the
construction of Lessee's leasehold improvements to the Premises
("Improvements"). As used herein, the term "Improvements" shall include all
work to be done in the Premises pursuant to the Plans, including, but not
limited to: demolition work, partitioning, doors, ceiling, floor coverings,
wall finishes (including paint and wallcovering), window coverings, electrical
(including lighting, switching, telephones, outlets, computer and special
electrical equipment), plumbing (including the installation of any bathrooms
within the Premises), heating, ventilating and air conditioning, fire
protection, hardware in compliance with current handicap requirements, cabinets
and other millwork, and any exterior signage. Within ten (10) business days
after receipt by Lessor of the Plans, Lessor (i) shall give its written
approval with respect thereto, or (ii) shall notify



<PAGE>   19

Lessee in writing of its disapproval and state with specificity the grounds for
such disapproval and the revisions or modifications necessary in order for
Lessor to gives its APPROVAL BASED ON THE CRITERIA SET FORTH IN PARAGRAPH 3
BELOW. Within three (3) business days following receipt by Lessor of such
revisions or modifications, Lessor shall give its written approval with respect
thereto or shall request other revisions or modifications therein (but relating
only to the extent Lessee has failed to comply with Lessor's earlier reasonable
requests). The preceding sentence shall be implemented repeatedly until Lessor
gives its approval to Lessee's Plans. After approval of the Plans by Lessor, no
further changes to the Plans shall be made without the prior written approval of
Lessor.

               (d) Code Compliance. Lessee acknowledges that Lessor's review and
approval of the Plans is not conducted for the purpose of determining the
accuracy, engineering, and/or design completeness of the Plans, their compliance
with applicable codes and governmental regulations or their sufficiency for
purposes of obtaining a building permit, all of which shall remain the
responsibility of Lessee and Lessee's design professionals.

        3.      Grounds for Disapproval

        Lessor shall not be required to approve any item of the Space Plan or
the Plans that: (a) do not conform to applicable governmental regulations or are
disapproved by any governmental agency; (b) materially affect the structure of
the Premises; (c) overload or otherwise compromise the roof, building structure,
or floors; or (d) are, in Lessor's reasonable opinion, of a nature or quality
that are inconsistent with the character and nature of space in a comparable
building.

        4.      Improvement Cost and Allowance

               (a) Selection of Contractor. Lessee shall submit to Lessor for
approval the names of Lessee's general contractor ("Contractor") and any
subcontractors intended to be used, which approval shall not be withheld
unreasonably. Lessee shall be required to utilize the Lessor's roof and fire
sprinkler contractors, PROVIDED SUCH CONTRACTORS ARE COST-COMPETITIVE. The
construction contract with the Contractor ("Construction Contract") shall
provide for not less than 10% retainage, customary owner protection regarding
the submission of unconditional lien release waivers from subcontractors and
suppliers prior to payment and the expiration of the applicable mechanics' lien
period prior to final payment, and sufficient time periods for review of payment
applications to permit the review by Lessee and Lessor specified above. Lessee
shall also designate a construction representative who shall be authorized to
give and receive instructions and approvals on behalf of Lessee.

               (b) Cost Breakdown. Promptly upon selection of the Contractor,
Lessee shall provide Lessor with a breakdown of the estimated total cost of the
Improvements ("Cost Breakdown"), including, without limitation: construction
cost of the Improvements; architectural and engineering fees relating to the
preparation and Lessor's review of the Space Plan and the Plans (Lessor's cost
shall be limited to Lessor's out-of-pocket costs payable to a third-party
architect to review the Space Plan and Plans not to exceed $1,000); governmental
agency plan check, permit and other fees; sales and use taxes; testing and
inspection costs; and construction fees (including the Contractor's overhead and
supervision fees and the construction supervisory fee referred to in Paragraph
6(c) hereof). Lessee shall furnish to Lessor a copy of the Construction Contract
and, upon Lessor's request, copies of any subcontracts, purchase orders or other
documentary evidence in support of the Cost Breakdown.

               (c) Payment of Contractor. Upon receipt of an application for a
progress payment from the Contractor, Lessee's architect shall promptly review
and certify the amounts due the Contractor. Lessee shall pay the Contractor all
amounts due the Contractor, in accordance with the provisions of the
Construction Contract. Lessee shall require the Contractor to provide Lessor
with the proper mechanics lien releases at the time of invoicing with such
releases conditioned upon payment and worded in the manner provided for
conditional releases under California law. Should there be any liens on the
Premises as a result of Lessee's Improvements, Lessor shall give written notice
thereof to Lessee and


<PAGE>   20

thereafter Lessee shall bear the costs to remove such liens by bonding or
otherwise.

               (d) Change in Plans. In the event that Lessee requests a change
in the Plans subsequent to approval of the Plans, Lessor shall approve or
disapprove such change within three (3) business days of written notice. Lessor
shall have the right to decline Lessee's request for a change in the approved
Plans if the change is inconsistent with Paragraphs 3 above.

        5.      Construction of Improvements

               (a) Construction. Upon approval of the Plans and submission of
the Cost Breakdown, Lessee shall instruct the Contractor to secure a building
permit and commence construction. Lessee shall use all commercially reasonable
efforts to complete construction of the Improvements as soon as possible.

               (b) Insurance. Lessee shall cause the Contractor to secure and
maintain, at Lessee's or the Contractor's expense, the following insurance
coverages in forms satisfactory to the Lessor and with insurance companies
having a minimum Best's rating of A: VII:

                      (i) Workers' compensation and Employers' Liability
Insurance as required by the laws of the State of California affording thirty
(30) days notice of cancellation to Lessor.

                      (ii) Commercial General Liability insurance in the amount
of Two Million Dollars ($2,000,000) combined single limit for bodily injury
and/or property damage liability including: an endorsement naming Lessor as
additional insured; an endorsement affording thirty (30) days notice to Lessor
in the event of cancellation or material reduction in coverage; and an
endorsement providing that such insurance as is afforded under the Contractor's
policy is primary insurance as respects Lessor and that any other insurance
maintained by Lessor is excess and non-contributing with the insurance required
hereunder.

               (c) Indemnity. Lessee agrees to indemnify Lessor with respect to
claims arising out of the operations conducted by the Contractor pursuant to the
indemnification provisions set forth in the Lease. Lessee shall keep the
Premises and the Project free from any mechanics' liens, vendors' liens or other
liens arising out of the work performed, materials furnished or obligations
incurred by Lessee hereunder, and agrees to defend, indemnify and hold harmless
Lessor from and against any such liens or actions thereon, together with costs
of suit and attorneys' fees.

               (d) Compliance with Law. The Improvements shall be done in
conformity both with all applicable codes and regulations of governmental
authorities having jurisdiction over the Premises and valid building permits and
other authorizations from appropriate governmental agencies when required.
Notwithstanding any failure to Lessor to object to any of the Improvements,
Lessor shall have no responsibility for code compliance or faulty work in
respect solely to the Improvements.

               (e) Building Entry. Lessee and Lessee's contractors shall abide
by all applicable safety and construction rules and regulations. Entry by
Lessee's contractors shall be deemed to be under all the terms, covenants,
provisions and conditions of the Lease except the covenant to pay rent. All
Lessee's materials, work, installations and decorations of any nature brought
upon or installed in the Premises shall be at Lessee's risk, and neither Lessor
nor any party acting on Lessor's behalf shall be responsible for any damage
thereto or loss or destruction thereof.

               (f) Reimbursement. Lessee shall reimburse Lessor for any extra,
out-of-pocket expense reasonably incurred by Lessor by reason of faulty work
done by Lessee or its contractors, or by reason of cleanup which fails to comply
with Lessor's rules and regulations, which are not promptly remedied by Lessee
after reasonable notice by Lessor.


<PAGE>   21

               (g) Signs. Lessee's contractors shall not post any signs other
than those required by law in connection with the construction on any part of
the Project or Premises.

        6.      Commencement Date

        Lessee's obligation to pay rent under the Lease shall commence upon the
Commencement Date as defined in Paragraph 1.3 of the Lease, and no delay in
construction, regardless of cause, shall delay the Commencement Date EXCEPT
DELAYS CAUSED BY THE NEGLIGENCE OR WILLFUL MISCONDUCT OF LESSOR, BREACH OF THIS
LEASE BY LESSOR, OR LESSOR'S FAILURE TO RESPOND WITHIN THE TIME FRAMES REQUIRED
IN THIS WORK LETTER AGREEMENT ("LESSOR DELAY"). THE COMMENCEMENT DATE SHALL BE
DELAYED ONE (1) DAY FOR EACH DAY OF LESSOR DELAY.

Paragraph ___

A.   RENT ADJUSTMENTS:
     The monthly rent for each month of the adjustment period(s) specified
below shall be increased using the method(s) indicated below:

(Check Method(s) to be Used and Fill in Appropriately)

[X]  I.   COST OF LIVING ADJUSTMENT(S) (COLA)

          a.   On (Fill in COLA Dates): May, 1, 2002, 2003, 2004, 2005, 2006,
2007, 2008, 2009, 2010 the Base Rent shall be adjusted by the change, if any,
from the Base Month specified below, in the Consumer Price Index of the Bureau
of Labor Statistics of the U.S. Department of Labor for (select one): [ ] CPI W
(Urban Wage Earners and Clerical Workers) or [X] CPI U (All Urban Consumers),
for (Fill in Urban Area): Los Angeles - Riverside - Orange County. All items
(1982-1984 = 100), herein referred to as "CPI".

          b.   The monthly rent payable in accordance with paragraph A.I.a. of
this Addendum shall be calculated as follows: the Base Rent set forth in
paragraph 1.5 of the attached Lease, shall be multiplied by a fraction the
numerator of which shall be the CPI of the calendar month two months prior to
the month(s) specified in paragraph A.I.a. above during which the adjustment is
to take effect, and the denominator of which shall be the CPI of the calendar
month which is two months prior to (select one): [ ] the first month of the
term of this Lease as set forth in paragraph 1.3 ("Base Month") or [ ] (Fill in
Other "Base Month"): $83,500.00. The sum so calculated shall constitute the new
monthly rent hereunder, but in no event, shall any such new monthly rent be
less than the rent payable for the month immediately preceding the rent
adjustment. There shall be a minimum of three percent (3%) and a maximum of six
percent (6%) per annum.

          c.   In the event the compilation and/or publication of the CPI shall
be transferred to any other governmental department or bureau or agency or
shall be discontinued, then the index most nearly the same as the CPI shall be
used to make such calculation. In the event that the Parties cannot agree on
such alternative index, then the matter shall be submitted for decision to the
American Arbitration Association in accordance with the then rules of said
Association and the decision of the arbitrators shall be binding upon the
parties. The cost of said Arbitration shall be paid equally by the Parties.

[ ]  II.  MARKET RENTAL VALUE ADJUSTMENT(S) (MRV)

          a.   On (Fill in MRV Adjustment Date(s): ___________________________
______________________________________________________________________________
the Base Rent shall be adjusted to the "Market Rental Value" of the property as
follows:

               1)   Four months prior to each Market Rental Value Adjustment
Date described above, the Parties shall attempt to agree upon what the new MRV
will be on the adjustment date. If agreement cannot be reached within thirty
days, then:

                    (a)  Lessor and Lessee shall immediately appoint a mutually
acceptable appraiser or broker to establish the new MRV within the next thirty
days. Any associated costs will be split equally between the Parties, or

                    (b)  Both Lessor and Lessee shall each immediately make a
reasonable determination of the MRV and submit such determination, in writing,
to arbitration in accordance with the following provisions:

                         (i)  Within fifteen days thereafter, Lessor and Lessee
shall each select an [ ] appraiser or [ ] broker ("Consultant" - check one) of
their choice to act as an arbitrator. The two arbitrators so appointed shall
immediately select a third mutually acceptable Consultant to act as a third
arbitrator.

                         (ii) The Three arbitrators shall within thirty days of
the appointment of the third arbitrator reach a decision as to what the actual
MRV for the Premises is, and whether Lessors' or Lessee's submitted MRV is the
closest thereto. The decision of a majority of the arbitrators shall be binding
on the Parties. The submitted MRV which is determined to be the closest to the
actual MRV shall thereafter be used by the Parties.

                         (iii) If either of the Parties fails to appoint an
arbitrator within the specified fifteen days, the arbitrator timely appointed
by one of them shall reach a decision on his or her own, and said decision
shall be binding on the Parties.

                         (iv)  The entire cost of such arbitration shall be
paid by the party whose submitted MRV is not selected, ie, the one that is NOT
closest to the actual MRV.

               2)   Notwithstanding the foregoing, the new MRV shall not be
less than the rent payable for the month immediately preceding the rent
adjustment.

<PAGE>   23
            b.    Upon the establishment of each New Market Rental Value:

                  1)    the new MRV will become the new "Base Rent" for the
                        purpose of calculating any further Adjustments, and

                  2)    the first month of each Market Rental Value term shall
                        become the new 'Base Month' for the purpose of
                        calculating any further Adjustments.

[ ]   III.  FIXED RENTAL ADJUSTMENT(S) (FRA)

The Base Rent shall be increased to the following amounts on the dates set

Lessee agree that, notwithstanding anything to the contrary in the Lease Form,
the Lease Form is hereby modified and supplemented as set forth below.

1.    CONDITION OF THE PREMISES: Landlord warrants and represents that as of
the Commencement Date TO THE BEST KNOWLEDGE OF THE LANDLORD the Premises
(including all structural and non-structural components thereof) will be in
good condition and repair and the electrical, mechanical, HVAC, plumbing,
elevator and other systems serving the Premises and the Building will be in
good condition and repair. LANDLORD REPRESENTS THAT THE MEZZANINE SHALL BE
CONSTRUCTED IN ACCORDANCE WITH APPLICABLE REQUIREMENTS. Tenant's acceptance of
the Premises shall not be deemed a waiver of Tenant's right to have defects in
the Mezzanine repaired at Landlord's sole expense. Tenant shall give notice to
Landlord whenever any such defect becomes reasonably apparent, and Landlord
shall repair such defect as soon as practicable. Landlord also hereby assigns
to Tenant all warranties with respect to the Premises which would reduce
Tenant's maintenance obligations hereunder and shall cooperate with Tenant to
enforce all such warranties.

3.    HAZARDOUS SUBSTANCES: Notwithstanding anything to the contrary in the
Lease Form, Lessor acknowledges and agrees that the Premises will be used for
the manufacture of microelectronics and that such use requires the use of
Hazardous Substances. Lessor hereby consents to the use of those Hazardous
Substances listed on Exhibit 1 to this Second Addendum and any Hazardous
Substances used in place of those listed on Exhibit 1 ("Replacement Hazardous
Substances") PROVIDED SUCH USE IS IN COMPLIANCE WITH APPLICABLE LAWS AND
REGULATIONS. Lessee shall provide Lessor a copy of the Hazardous Materials
Business Plan ("HMBP") it will submit to the relevant governmental agency for
the facility as well as a copy of any updates to the HMBP at the time such
updates are submitted. To the best knowledge of Lessor, except as previously
disclosed in writing to Lessee, (i) no Hazardous Substances are present on or
about the Premises or the soil, surface water or groundwater thereof, (ii) no
underground storage tanks or asbestos-containing building materials are present
on the Premises and (iii) no action, proceeding or claim is pending or
threatened regarding the Premises concerning any Hazardous Substances or
pursuant to any law. Lessor has delivered to Lessee all reports and
environmental assessments of the Premises conducted at the request of or
otherwise available to Lessor. Under no circumstance shall Lessee be liable
for, and Lessor shall indemnify, defend with counsel reasonably acceptable to
Lessee, protect and hold harmless Lessee, its employees, agents, contractors,
stockholders, directors, officers, subtenants, successors, representatives, and
assigns from and against, all claims, losses, costs, damages, liabilities, and
expenses (including attorneys' and consultants' fees) of every type and nature,
directly or indirectly arising out of or in connection with any Hazardous
Substances present at any time on or about the Premises or the soil, air,
improvements, groundwater or surface water thereof, or the violation of any law
relating to any such Hazardous Substance, except to the extent THAT SUCH
HAZARDOUS SUBSTANCE WERE PRESENT PRIOR TO LESSEE'S OCCUPANCY TO THE PREMISES.
This Section 3 and Section 6.2 of the Lease Form are the SOLE provisions of the
Lease pertaining to Hazardous Substances and no other provision shall be deemed
to apply thereto.

4. INSPECTION; COMPLIANCE: Lessor and Lessor's agents, except in the case of
emergency, shall provide Lessee with twenty-four (24) hours' notice prior to
entry of the Premises. Any such entry by Lessor and Lessor's agents shall comply
with all reasonable security measures of Lessee and shall not impair Lessee's
operations more than reasonably necessary.

5. MAINTENANCE AND REPAIRS: Lessor shall perform and construct, at Lessor's sole
cost and expense, and Lessee shall have no obligation to perform or pay for, any
repair, maintenance or improvements (a) necessitated by the acts or omissions of
Lessor, or its agents, employees, licensees, invitees or contractors AFTER THE
COMMENCEMENT DATE, (b) required as a consequence of any violation of any
Applicable Requirements or construction defects in the Premises as of the
Commencement Date, (c) for which Lessor has a right of reimbursement from others
and (d) to the structural elements of the Premises, the roof structure, exterior
walls, load-bearing walls and the Building foundation. Additionally, if any of
Lessee's obligations under the Lease (as modified by this Addendum) would
require Lessee to pay all or any portion of any charge which would be treated as
a capital improvement under generally accepted accounting principles or a
"Capital Expenditure" as defined in this Lease, then Lessor shall make such
replacement at its sole expense, but the cost thereof shall be amortized and
Lessee shall pay Additional Rent on account of such amortization in accordance
with the following procedures: the cost of such repair or replacement shall be
amortized on a straight line basis over the useful life of such replacement
(determined in accordance with generally accepted accounting principles). As
Additional Rent, Lessee shall pay an amount equal to such monthly amortization
payment for each month after such replacement is completed until the first to
occur of (i) the expiration of the term of the Lease, or (ii) the end of the
term over which such costs were amortized. The monthly amount of such Additional
Rent shall be due at the same time the Base Rent is due.

6. UTILITY INSTALLATIONS AND ALTERATIONS: All Utility Installations,
Alterations, Trade Fixtures and personal property installed in the Premises at
Lessee's expense (including the "Improvements" as defined in the Work Letter
Agreement) (collectively "Lessee's Property") shall at all times remain Lessee's
property and Lessee shall be entitled to all depreciation, amortization and
other tax benefits with respect thereto. Except for Utility Installations or
Alterations which cannot be removed without structural injury to the Premises,
at any time Lessee may remove Lessee's Property from the Premises, provided
Lessee repairs all damage caused by such removal. If Lessor's consent is
required for a Utility Installation or Alteration and Lessor does not notify
Lessee in writing of its reasonable disapproval within fifteen (15) days
following Lessee's request for approval, then Lessor shall be deemed to have
approved the proposed Utility Installation or Alteration. Upon request, Lessor
shall advise Lessee in writing whether it will require Lessee to remove any
Alterations or Utility Installations from the Premises upon termination of the
Lease. NOTWITHSTANDING ANYTHING TO THE CONTRARY HEREIN, LESSOR MAY CONDITION ITS
APPROVAL OF ANY UTILITY INSTALLATION, ALTERATION OR IMPROVEMENT ON LESSEE'S
AGREEMENT TO REMOVE SUCH UTILITY INSTALLATION, ALTERATION OR IMPROVEMENTS AT THE
END OF THE TERM. If Lessor fails to make such a requirement a condition to its
approval, Lessee shall not be required to remove any Alterations or Utility
Installations upon the Expiration Date or sooner termination of the Lease.
Lessee shall be entitled to all insurance proceeds and condemnation awards and
settlements payable with respect to Lessee's Property. Lessee shall not be
required to remove the following Improvements (as defined in the Work Letter
Agreement) from the Premises at the end of the Term [NEED TO DETERMINE IF THERE
ARE IMPROVEMENTS THAT WILL REMAIN IN THE PREMISES]. Notwithstanding anything to
the contrary in the Lease Form, the Lessee shall be permitted to remove all lab
benches, clean rooms [NEED ADDITIONAL LIST IF ANY] from the Premises at the end
of the Term.

7. SURRENDER: Lessee's obligation to surrender the Premises shall be fulfilled
if Lessee surrenders possession of the Premises in the condition existing on the
Start Date, ordinary wear and tear, acts of God, casualties, condemnation,
Hazardous Substances (other than those released or emitted by Lessee, its agents
or invitees), and Alterations and Utility Installations which Lessee elects to
surrender, all excepted.

8. PROPERTY INSURANCE: In no event shall Lessee have any obligation to pay or
reimburse Lessor for any premiums for earthquake insurance to the extent
exceeding commercially reasonable rates.

9. WAIVER OF SUBROGATION: The terms of Paragraph 8.6 of the Lease shall be
applicable to Lessor and Lessee, notwithstanding anything to the contrary in the
Lease Form, and the waiver and release therein shall be applicable to Lessor's
and Lessee's respective agents, employees, contractors,

successors, assignees and subtenants and shall also apply to any perils actually
insured against by either Lessor or Lessee, without regard to the negligence or
willful misconduct of the party so released.

11. ASSIGNMENT AND SUBLETTING: Lessee may, without Lessor's prior written
consent, sublet any or all of the Premises or assign the Lease to: (i) a
subsidiary, affiliate, division or corporation controlling, controlled by or
under common control with Lessee; (ii) a successor corporation related to Lessee
by merger, consolidation, nonbankruptcy reorganization, or government action; or
(iii) a purchaser of SUBSTANTIALLY ALL OF THE ASSETS OF NEW FOCUS, INC. THE
ORIGINAL LESSEE (the "Permitted Assignees"). Any sale or transfer of Lessee's
capital stock shall not be deemed an assignment, subletting, or any other
transfer of the Lease or the Premises. If Lessor fails to respond to Lessee's
request to assign or sublet the Premises within fifteen (15) days following
Lessor's receipt of Lessee's request, Lessor shall be deemed to have consented
to such assignment or sublet of the Premises.

12. REAL PROPERTY TAXES: Lessee shall only be required to pay to Lessor that
amount of any Real Property Taxes based on the installments of principal and
interest which would have become due during the Lease Term had Lessor elected to
pay the assessment in installments over the longest permitted term. Lessee shall
pay the Real Property Taxes applicable to the Premises within (i) twenty (20)
days after receipt of billing; or (ii) ten (10) days prior to the delinquency
date of such Real Property Taxes, whichever is later.

13. SIGNS: Lessee shall have the right to install the signage described in
Exhibit 2 hereto, subject to the approval of the City of Camarillo.

15. EFFECT OF ADDENDUM: All terms with initial capital letters used herein as
defined terms shall have the meanings ascribed to them in the Lease Form, unless
specifically defined herein. In the event of any inconsistency between this
Second Addendum and the Lease Form, the terms of this Second Addendum shall
prevail. As used herein, the term Lease shall mean the Lease Form, the Second
Addendum and all riders, exhibits, rules and regulations referred to in the
Lease Form and this Second Addendum.

16. DELAWARE CORPORATION: Notwithstanding anything to the contrary in the Lease
or any documents thereto, New Focus, Inc. is a Delaware Corporation not a
California Corporation.
