<PAGE>   2
         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 square footage set forth in this Lease, or
that may have been used in calculating rental, is an approximation which Lessor
and Lessee agree is reasonable and the rental based therein is not subject to
revision whether or not the actual square footage is more or less.

         2.2 CONDITION. Lessor shall deliver the Premises to Lessee clean and
free of debris on the Commencement Date and warrants to Lessee that the existing
plumbing, fire sprinkler system, lighting, air conditioning, heating, and
loading doors, if any, in the Premises, other than those constructed by Lessee,
shall be in good operating condition on the Commencement Date. If a
non-compliance with said warranty exists as of the Commencement Date, Lessor
shall, except as otherwise provided in this Lease, promptly after receipt of
written notice from Lessee setting forth with specificity the nature and extent
of such non-compliance, rectify same at Lessor's expense, If Lessee does not
give Lessor written notice of a non-compliance with this warranty within thirty
(30) days after the Commencement Date, correction of that non-compliance shall
be the obligation of Lessee at Lessee's sole cost and expense.

         2.3 COMPLIANCE AND COVENANTS, RESTRICTIONS AND BUILDING CODE. Lessor
warrants to Lessee that the improvements on the Premises comply with all
applicable covenants or restrictions of record and applicable building codes,
regulations and ordinances in effect on the Commencement 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. If the Premises do not comply with said warranty, Lessor
shall, except as otherwise provided in this Lease, 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 six (6)
months following the Commencement Date, correction of that non-compliance shall
be the obligation of Lessee at Lessee's sole cost and expense.

         2.4 ACCEPTANCE OF PREMISES. Lessee hereby acknowledges: (a) that it has
been advised by the Brokers to satisfy itself with respect to the condition of
the Premises (including but not limited to the electrical and fire sprinkler
systems, security, environmental aspects, compliance with Applicable Law, as
defined in Paragraph 6.3) and the present and future suitability of the Premises
for Lessee's intended use, (b) that Lessee has made such investigation as it
deems necessary with reference to such matters and assumes all responsibility
therefor as the same relate to Lessee's occupancy of the Premises and/or the
term of this Lease, and (c) that neither Lessor, nor any of Lessor's agents, has
made any oral or written representations or warranties with respect to the said
matters other than as set forth in this Lease.

         2.5 LESSEE PRIOR OWNER/OCCUPANT. The warranties made by Lessor in this
Paragraph 2 shall be of no force or effect if immediately prior to the date set
forth in Paragraph 1.1 Lessee was the owner or occupant of the Premises. In such
event, Lessee shall, at Lessee's sole cost and expense, correct any
non-compliance of the Premises with said warranties.

3.       TERM.

         3.1 TERM. The Commencement Date, Expiration Date and Original Term of
this Lease are as specified in Paragraph 1.3 See Addendum #49.

         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, however, (including but not limited to the obligations to pay Real
Property Taxes and insurance premiums and to maintain the Premises) shall be in
effect during such period. Any such early possession shall not affect nor
advance the Expiration Date of the Original Term. See Addendum #50.

         3.3 DELAY IN POSSESSION. If for any reason Lessor cannot deliver
possession of the Premises to Lessee as agreed herein by the Early Possession
Date, if one is specified in Paragraph 1.4, or, if no Early Possession Date


                                        2
<PAGE>   3
is specified, by the Commencement Date, Lessor shall not be subject to any
liability therefor, nor shall such failure affect the validity of this Lease, or
the obligations of Lessee hereunder, or extend the term hereof, but in such
case, Lessee shall not, except as otherwise provided herein, be obligated to pay
rent or perform any other obligation of Lessee under the terms of this Lease
until Lessor delivers possession of the Premises to Lessee. If possession of the
Premises is not delivered to Lessee within sixty (60) days after the
Commencement Date, Lessee may, at its option, by notice in writing to Lessor
within ten (10) days thereafter, cancel this Lease, in which event the Parties
shall be discharged from all obligations hereunder; provided, however, that if
such written notice by Lessee is not received by Lessor within said ten (10) day
period, Lessee's right to cancel this Lease shall terminate and be of no further
force or effect. Except as may be otherwise provided, and regardless of when the
term actually commences, if possession is not tendered to Lessee when required
by this Lease and Lessee does not terminate this Lease, as aforesaid, the period
free of the obligation to pay Base Rent, if any, 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, changes or omissions of
Lessee.

4.       RENT.  See Addendum #51.

         4.1 BASE RENT. Lessee shall cause payment of Base Rent and other rent
or charges, as the same may be adjusted from time to time, to be received by
Lessor in lawful money of the United States, without offset or deduction, on or
before the day on which it is due under the terms of this Lease. Base Rent and
all other rent and charges 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 the calendar month involved. Payment of Base Rent and other
charges shall be made to Lessor at its address stated herein or to such other
persons or at such other addresses as Lessor may from time to time designate in
writing to Lessee.

5.       SECURITY DEPOSIT. Lessee shall deposit with Lessor upon execution
hereof the Security Deposit set forth in Paragraph 1.7 as security for Lessee's
faithful performance of Lessee's obligations under this Lease. If Lessee fails
to pay Base Rent or other rent or charges due hereunder, or otherwise Defaults
under this Lease (as defined in Paragraph 13.1), 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, cost, expense,
loss or damage (including attorneys' fees) 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 moneys with Lessor sufficient to restore said Security Deposit to the
full amount required by this Lease. Any time the Base Rent increases during the
term of this Lease, Lessee shall, upon written request from Lessor, deposit
additional moneys with Lessor sufficient to maintain the same ratio between the
Security Deposit and the Base Rent as those amounts are specified in the Basic
Provisions. Lessor shall not be required to keep all or any part of the Security
Deposit separate from its general accounts. Lessor shall, at the expiration or
earlier termination of the term hereof and after Lessee has vacated the
Premises, return to Lessee (or, at Lessor's option, to the last assignee, if
any, of Lessee's interest herein), that portion of the Security Deposit not used
or applied by Lessor. Unless otherwise expressly agreed in writing by Lessor, no
part of the Security Deposit shall be considered to be held in trust, to bear
interest or other increment for its use, or to be prepayment for any moneys to
be paid by Lessee under this Lease.

6.       USE.

         6.1 USE. Lessee shall use and occupy the Premises only for the purposes
set forth in Paragraph 1.8, or any other use which is comparable thereto, and
for no other purpose. Lessee shall not use or permit the use of the Premises in
a manner that creates waste or a nuisance, or that disturbs owners and/or
occupants of, or causes damage to, neighboring premises or properties.

         6.2 HAZARDOUS SUBSTANCES. See Addendum #52.

                  (a) REPORTABLE USES REQUIRE CONSENT. The term "HAZARDOUS
SUBSTANCE" as used in this Lease shall mean any product, substance, chemical,
material or waste whose presence, nature, quantity and/or intensity of
existence, use, manufacture, disposal, transportation, spill, release or effect,
either by itself or in



                                        3
<PAGE>   4
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 liability of Lessor to any governmental agency or third party
under any applicable statute or common law theory. Hazardous Substance shall
include, but not be limited to, hydrocarbons, petroleum, gasoline, crude oil or
any products, by-products or fractions thereof. Lessee shall not engage in any
activity in, on or about the Premises which constitutes a Reportable Use (as
hereinafter defined) of Hazardous Substances without the express prior written
consent of Lessor and compliance in a timely manner (at Lessee's sole cost and
expense) with all Applicable Law (as defined in Paragraph 6.3). "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, Reportable Use shall also include Lessee's being
responsible for the presence in, on or about the Premises of Hazardous Substance
with respect to which any Applicable Law requires that a notice be given to
persons entering or occupying the Premises or neighboring properties.
Notwithstanding the foregoing, Lessee may, without Lessor's prior consent, but
in compliance with all Applicable Law, use any ordinary and customary materials
reasonably required to be used by Lessee in the normal course of Lessee's
business permitted on the Premises, so long as such use is not a Reportable Use
and does not expose the Premises or neighboring properties to any meaningful
risk of contamination or damage or expose Lessor to any liability therefor. In
addition, Lessor may (but without any obligation to do so) condition its consent
to the use or presence of any Hazardous Substance, activity or storage tank by
Lessee upon Lessee's giving Lessor such additional assurances as Lessor, in its
reasonable discretion, deems necessary to protect itself, the public, the
Premises and the environment against damage, contamination or injury and/or
liability therefrom or therefor, including, but not limited to, the installation
(and removal on or before Lease expiration or earlier termination) of reasonably
necessary protective modifications to the Premises (such as concrete
encasements) and/or the deposit of an additional Security Deposit under
Paragraph 5 hereof.

         (b) DUTY TO INFORM LESSOR. If Lessee knows, or has reasonable cause to
believe, that a Hazardous Substance, or a condition involving or resulting from
same, 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. Lessee shall also immediately give Lessor a copy of any
statement, report, notice, registration, application, permit, business plan,
license, claim, action or proceeding given to, or received from, any
governmental authority or private party, or persons entering or occupying the
Premises, concerning the presence, spill, release discharge of, or exposure to,
any Hazardous Substance or contamination in, on, or about the Premises,
including but not limited to all such documents as may be involved in any
Reportable Uses involving the Premises.

         (c) INDEMNIFICATION. Lessee shall indemnify, protect, defend and hold
Lessor, its agents, employees, lenders and ground lessor, if any, and the
Premises, harmless from and against any and all loss of rents and/or damages,
liabilities, judgments, costs, claims, liens, expenses, penalties, permits and
attorney's and consultant's fees arising out of or involving any Hazardous
Substance or storage tank brought onto the Premises by or for Lessee or under
Lessee's control. Lessee's obligations under this Paragraph 6 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 (including consultant's and attorney's fees and testing), removal,
remediation, restoration and/or abatement thereof, or of any contamination
therein involved, and shall survive the expiration or earlier termination of
this Lease. No termination, cancellation or release agreement entered into by
Lessor and Lessee shall release Lessee from its obligations under this Lease
with respect to Hazardous Substances or storage tanks, unless specifically so
agreed by Lessor in writing at the time of such agreement.

         6.3 LESSEE'S COMPLIANCE WITH LAW. Except as otherwise provided in this
Lease, Lessee, shall, at Lessee's sole cost and expense, fully, diligently and
in a timely manner, comply with all "APPLICABLE LAW," which term is used in this
Lease to include all laws, rules, regulations, ordinances, directives,
covenants, easements and restrictions of record, permits, the requirements of
any applicable fire insurance underwriter or rating bureau, and the
recommendations of Lessor's engineers and/or consultants, relating in any manner
to the Premises (including but not limited to matters pertaining to (i)
industrial hygiene, (ii) environmental conditions on, in, under or about the
Premises, including soil and groundwater conditions, and (iii) the use,
generation, manufacture, production,


                                        4
<PAGE>   5
installation, maintenance, removal, transportation, storage, spill or release of
any Hazardous Substance or storage tank), now in effect or which may hereafter
come into effect, and whether or not reflecting a change in policy from any
previously existing policy. Lessee shall, within five (5) days after receipt of
Lessor's written request, provide Lessor with copies of all documents and
information, including, but not limited to, permits, registrations, manifests,
applications, reports and certificates, evidencing Lessee's compliance with any
Applicable Law 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 failure by Lessee or the Premises to comply with any Applicable Law.
SEE ADDENDUM #53

         6.4 INSPECTION; COMPLIANCE. Lessor and Lessor's Lender(s) (as defined
in Paragraph 8.3(a)) 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
inspecting the condition of the Premises and for verifying compliance by Lessee
with this Lease and all Applicable Laws (as defined in Paragraph 6.3), and to
employ experts and/or consultants in connection therewith and/or to advise
Lessor with respect to Lessee's activities, including but not limited to the
installation, operation, use, monitoring, maintenance, or removal of any
Hazardous Substance or storage tank on or from the Premises. The costs and
expenses of any such inspections shall be paid by the party requesting same,
unless a Default or Breach of this Lease, violation of Applicable Law, or a
contamination, caused or materially contributed to by Lessee is found to exist
or be imminent, or unless the inspection is requested or ordered by a
governmental authority as the result of any such existing or imminent violation
or contamination. In any such case, Lessee shall upon request reimburse Lessor 
or Lessor's Lender, as the case may be, for the costs and expenses of such 
inspections.

under Paragraph 7.1 hereof. 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. Lessee and Lessor expressly waive the benefit of any
statute now or hereafter in effect to the extent it is inconsistent with the
terms of this Lease with respect to, or which affords Lessee the right to make

needed repairs.

         7.3 UTILITY INSTALLATIONS; TRADE FIXTURES; ALTERATIONS.

coverings, air lines power panels, electrical distribution, security, fire
protection systems, communication systems, lighting fixtures, heating,
ventilating, and air conditioning equipment, plumbing, and fencing in, on or
about 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 on the
Premises from that which are provided by Lessor under the terms of this Lease,
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 as defined in Paragraph 7.4(a). Lessee shall not make any Alterations
or Utility Installations in, on, under or about 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), 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
the term of this Lease as extended does not exceed $25,000.

                  (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 proposed detailed plans. All consents
given by Lessor, whether by virtue of Paragraph 7.3(a) or by subsequent specific
consent, shall be deemed conditioned upon: (i) Lessee's acquiring all applicable
permits required by governmental authorities, (ii) the furnishing of copies of
such permits together with a copy of the plans and specifications for the
Alteration or Utility Installation to Lessor prior to commencement of the work
thereon, and (iii) the compliance by Lessee with all conditions of said permits
in a prompt and expeditious manner. Any Alterations or Utility Installations by
Lessee during the term of this Lease shall be done in a good and workmanlike
manner, with good and sufficient materials, and in compliance with all
Applicable Law. Lessee shall promptly upon completion thereof furnish Lessor
with as-built plans and specifications therefor. Lessor may (but without
obligation to do so) condition its consent to any requested Alteration or
Utility Installation that costs $10,000 or more upon Lessee's providing Lessor
with 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 under Paragraph 36 hereof.

                  (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
mechanics' 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,


                                        6
<PAGE>   7
and Lessor shall have the right to post notices of non-responsibility in or on
the Premises as provided by law. If Lessee shall, in good faith, contest the
validity of any such lien, claim or demand, then Lessee shall, at its sole
expense defend 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 against the Lessor or the Premises. If Lessor
shall require, Lessee shall furnish to Lessor a surety bond satisfactory to
Lessor 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, as
required by law for the holding of the Premises free from the effect of such
lien or claim. In addition, Lessor may require Lessee to pay Lessor's attorney's
fees and costs in participating in such action if Lessor shall decide it is to
its best interest to do so.

         7.4 OWNERSHIP; REMOVAL; SURRENDER; AND RESTORATION.

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

                  (b) REMOVAL. Unless otherwise agreed in writing, Lessor may
require that any or all Lessee Owned Alterations or Utility Installations be
removed by the expiration or earlier termination of this Lease, notwithstanding
their installation may have been consented to by Lessor. 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 of Lessor.

                  (c) SURRENDER/RESTORATION. Lessee shall surrender the Premises
by the end of the last day of the Lease term or any earlier termination date,
with all of the improvements, parts and surfaces thereof 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 or by
Lessee performing all of its obligations under this Lease. Except as otherwise
agreed or specified in writing by Lessor, the Premises, as surrendered, shall
include the Utility Installations. The obligation of Lessee shall include the
repair of any damage occasioned by the installation, maintenance or removal of
Lessee's Trade Fixtures, furnishings, equipment, and Alterations and/or Utility
Installations, 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
ground water contaminated by Lessee, all as may then be required by Applicable
Law and/or good practice. Lessee's Trade Fixtures shall remain the property of
Lessee and shall be removed by Lessee subject to its obligation to repair and
restore the Premises per this Lease.

8.       INSURANCE; INDEMNITY.

         8.1 PAYMENT FOR INSURANCE. Regardless of whether the Lessor or Lessee
is the Insuring Party. Lessee shall pay for all Insurance required under this
Paragraph 8 except to the extent of the cost attributable to liability insurance
carried by Lessor in excess of $1,000,000 per occurrence. Premiums for policy
periods commencing prior to or extending beyond the Lease term shall be prorated
to correspond to the Lease term. Payment shall be made by Lessee to Lessor
within ten (10) days following receipt of an invoice for any amount due.

         8.2 LIABILITY INSURANCE.

                  (a) CARRIED BY LESSEE. Lessee shall obtain and keep in force
during the term of this Lease a Commercial General Liability policy of Insurance
protecting Lessee and Lessor (as an additional insured) against claims for
bodily injury, personal injury and property damage based upon, involving or
arising out of the ownership, use, occupancy or maintenance of the Premises and
all areas appurtenant thereto. Such insurance shall be on an


                                        7
<PAGE>   8
occurrence basis providing single limit coverage in an amount not less than
$1,000,000 per occurrence with an "Additional Insured-Managers or Lessors of
Premises" Endorsement and contain the "Amendment of the Pollution Exclusion" for
damage caused by heat, smoke or fumes from a hostile fire. The policy shall not
contain any intra-insured exclusions as between insured persons or
organizations, but shall include coverage for liability assumed under this Lease
as an "insured contract" for the performance of Lessee's indemnity obligations
under this Lease. The limits of said insurance required by this Lease or as
carried by Lessee shall not, however, limit the liability of Lessee nor relieve
Lessee of any obligation hereunder. All insurance to be 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. In the event Lessor is the Insuring
Party, Lessor shall also maintain liability insurance described in Paragraph
8.2(a), above, 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 during the term of this Lease a policy or policies in the name
of Lessor, with loss payable to Lessor and to the holders of any mortgages,
deeds of trust or ground leases on the Premises ("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 Lenders, but in no event more than the commercially
reasonable and available insurable value thereof if, by reason of the unique
nature or age of the improvements involved, such latter amount is less than full
replacement cost. If Lessor is the Insuring Party, however, Lessee Owned
Alterations and Utility Installations 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),
including coverage for any additional costs resulting from debris removal and
reasonable amounts of coverage for the enforcement of any ordinance or law
regulating the reconstruction or replacement of any undamaged sections of the
Premises required to be demolished or removed by reason of the enforcement of
any building, zoning, safety or land use laws as the result of a covered cause
of 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, as defined
in Paragraph 9.1(c).

                  (b) RENTAL VALUE. The Insuring Party shall, in addition,
obtain and keep in force during the term of this Lease a policy or policies in
the name of Lessor, with loss payable to Lessor and Lender(s), insuring the loss
of the full rental and other charges payable by Lessee to Lessor under this
Lease for one (1) year (including all real estate taxes, insurance costs, and
any scheduled rental increases). Said insurance shall provide that in the event
the Lease is terminated by reason of an insured loss, the period of indemnify
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 rental
revenues 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 rental income,
property taxes, insurance premium costs and other expenses, if any, 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 if the Premises are part 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
<PAGE>   9
                  (d) TENANT'S IMPROVEMENTS. If the Lessor is the Insuring
Party, the Lessor shall not be required to insure Lessee Owned Alterations and
Utility Installations unless the item in question has become the property of
Lessor under the terms of this Lease. If Lessee is the Insuring Party, the
policy carried by Lessee under this Paragraph 8.3 shall insure Lessee Owned
Alterations and Utility Installations.

         8.4 LESSEE'S PROPERTY INSURANCE. Subject to the requirements of
Paragraph 8.5, Lessee at its cost shall either by separate policy or, at
Lessor's option, by endorsement to a policy already carried, maintain insurance
coverage on all of Lessee's personal property, Lessee Owned Alterations and
Utility Installations in, on, or about the Premises similar in coverage to that
carried by the Insuring Party under Paragraph 8.3. Such insurance shall be full
replacement cost coverage with a deductible of not to exceed $1,000 per
occurrence. The proceeds from any such insurance shall be used by Lessee for the
replacement of personal property or the restoration of Lessee Owned Alterations
and Utility Installations. Lessee shall be the Insuring Party with respect to
the insurance required by this Paragraph 8.4 and shall provide Lessor with
written evidence that such insurance is in force. SEE ADDENDUM #55

         8.5 INSURANCE POLICIES. Insurance required hereunder shall be in
companies duly licensed 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, or such other rating as may be required by a Lender having a
lien on the Premises, as set forth in the most current issue of "Best's
Insurance Guide" Lessee shall not do or permit to be done anything which shall
invalidate the insurance policies referred to in this Paragraph 8. If Lessee is
the Insuring Party, Lessee shall cause to be delivered to Lessor certified
copies of policies of such insurance or certificates evidencing the existence
and amounts of such insurance with the insureds and loss payable clauses as
required by this Lease. 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. If the
Insuring Party shall fail to procure and maintain the insurance required to be
carried by the Insuring Party under this Paragraph 8, the other Party may, but
shall not be required to, procure and maintain the same, but at Lessee's
expense.

         8.6 WAIVER OF SUBROGATION. Without affecting any other rights or
remedies, Lessee and Lessor ("WAIVING PARTY") each hereby release and relieve
the other, and waive their entire right to recover damages (whether in contract
or in tort) against the other, for loss of or damage to the Waiving Party's
property arising out of or incident to the perils required to be insured against
under Paragraph 8. The effect of such releases and waivers of the right to
recover damages shall not be limited by the amount of insurance carried or
required, or by any deductibles applicable thereto.

         8.7 INDEMNITY. Except for Lessor's negligence and/or breach of express
warranties, 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,
costs, liens, judgments, penalties, permits, attorney's and consultant's fees,
expenses and/or liabilities arising out of, involving, or in dealing with, the
occupancy of the Premises by Lessee, the conduct of Lessee's business, any act,
omission or neglect of Lessee, its agents, contractors, employees or invitees,
and out of any Default or Breach by Lessee in the performance in a timely manner
of any obligation on Lessee's part to be performed under this Lease. The
foregoing shall include, but not be limited to, the defense or pursuit of any
claim or any action or proceeding involved therein, and whether or not (in the
case of claims made against Lessor) litigated and/or reduced to judgment, and
whether well founded or not. In case any action or proceeding be brought against
Lessor by reason of any of the foregoing matters, Lessee upon notice from Lessor
shall defend the same at Lessee's expense by counsel reasonably satisfactory to
Lessor and Lessor shall cooperate with Lessee in such defense. Lessor need not
have first paid any such claim in order to be so indemnified.

         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


                                        9
<PAGE>   10
from fire, steam, electricity, gas, water or rain, or from the breakage,
leakage, obstruction or other defects of pipes, fire sprinklers, wires,
appliances, plumbing, air conditioning 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, and regardless of whether the cause of
such damage or injury or the means of repairing the same is accessible or not.
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. SEE ADDENDUM #56

9.       DAMAGE OR DESTRUCTION.

         9.1 DEFINITIONS.

                  (a) "PREMISES PARTIAL DAMAGE" shall mean damage or destruction
to the improvements on the Premises, other than Lessee Owned Alterations and
Utility Installations, the repair cost of which damage or destruction is less
than 50% of the then Replacement Cost of the Premises immediately prior to such
damage or destruction, excluding from such calculation the value of the land and
Lessee Owned Alterations and Utility Installations.

                  (b) "PREMISES TOTAL DESTRUCTION" shall mean damage or
destruction to the Premises, other than Lessee Owned Alterations and Utility
Installations the repair cost of which damage or destruction is 50% or more of
the then Replacement Cost of the Premises immediately prior to such damage or
destruction, excluding from such calculation the value of the land and Lessee
Owned Alterations and Utility Installations.

                  (c) "INSURED LOSS" shall mean damage or destruction to
improvements on the Premises, other than Lessee Owned Alterations and Utility
Installations, 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 building codes,
ordinances or laws, and without deduction for depreciation.

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

         9.2 PARTIAL DAMAGE--INSURED LOSS. If a Premises Partial Damage that is
an Insured Loss occurs, then Lessor shall, at Lessor's expense, repair such
damage (but not Lessee's Trade Fixtures or Lessee Owned Alterations and Utility
Installations) as soon as reasonably possible and this Lease shall continue in
full force and effect; provided, however, that Lessee shall, at Lessor's
election, make the repair of any damage or destruction the total cost to repair
of which is $10,000 or less, and, in such event, Lessor shall make the 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, the shortage in proceeds 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
Lessor does not receive such funds or assurance within said period, Lessor may
nevertheless elect by written


                                       10
<PAGE>   11
notice to Lessee within ten (10) days thereafter to 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. If in such case
Lessor does not so elect, then this Lease shall terminate sixty (60) days
following the occurrence of the damage or destruction. Unless otherwise agreed,
Lessee shall in no event have any right to reimbursement from Lessor for 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
rather than Paragraph 9.2, 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 and
this Lease shall continue in full force and effect, but subject to Lessor's
rights under Paragraph 13), Lessor may at Lessor's option, 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) give written notice
to Lessee within thirty (30) days after receipt by Lessor of knowledge of the
occurrence of such damage of Lessor's desire to terminate this Lease as of the
date sixty (60) days following the giving of such notice. In the event Lessor
elects to give such notice of Lessor's intention to terminate this Lease, Lessee
shall have the right within ten (10) days after the receipt of such notice to
give written notice to Lessor of Lessee's commitment to pay for the repair of
such damage totally at Lessee's expense and without reimbursement from Lessor.
Lessee shall provide Lessor with the required funds or satisfactory assurance
thereof within thirty (30) days following Lessee's said commitment. In such
event this Lease shall continue in full force and eject, and Lessor shall
proceed to make such repairs as soon as reasonably possible and the required
funds are available. If Lessee does not give such notice and provide the funds
or assurance thereof within the times specified above, this Lease shall
terminate as of the dale specified in Lessor's notice of termination.

         9.4 TOTAL DESTRUCTION. Notwithstanding any other provision hereof, if a
Premises Total Destruction occurs (including any destruction required by any
authorized public authority), this Lease shall terminate sixty (60) days
following the date of such Premises Total Destruction, whether or not the damage
or destruction is an Insured Loss or was caused by a negligent or willful act of
Lessee. In the event, however, that the damage or destruction was caused by
Lessee, Lessor shall have the right to recover Lessor's damages from Lessee
except as released and waived in Paragraph 8.6. SEE ADDENDUM #5

         9.5 DAMAGE NEAR END OF TERM. If at any time during the last six (6)
months of the term of this Lease there is damage for which the cost to repair
exceeds one (1) month's Base Rent, whether or not an Insured Loss, Lessor may,
at Lessor's option, terminate this Lease effective sixty (60) days following the
date of occurrence of such damage by giving written notice to Lessee of Lessor's
election to do so within thirty (30) days after the date of occurrence of such
damage. Provided, however, 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, within twenty (20) days following the occurrence of the damage, or
before the expiration of the time provided in such option for its exercise,
whichever is earlier ("Exercise Period"), (i) exercising such option and (ii)
providing Lessor with any shortage in insurance proceeds (or adequate assurance
thereof) needed to make the repairs. If Lessee duly exercises such option during
said Exercise Period and provides Lessor with funds (or adequate assurance
thereof) to cover any shortage in insurance proceeds, Lessor shall, at Lessor's
expense repair such damage as soon as reasonably possible and this Lease shall
continue in full force and effect. If Lessee falls to exercise such option and
provide such funds or assurance during said Exercise Period, then Lessor may at
Lessor's option terminate this Lease as of the expiration of said sixty (60) day
period following the occurrence of such damage by giving written notice to
Lessee of Lessor's election to do so within ten (10) days after the expiration
of the Exercise Period, notwithstanding any term or provision in the grant of
option to the contrary. SEE ADDENDUM #58

         9.6 ABATEMENT OF RENT; LESSEE'S REMEDIES. SEE ADDENDUM #59

                  (a) In the event of damage described in Paragraph 9.2 (Partial
Damage-Insured), whether or not Lessor or Lessee repairs or restores the
Premises, the Base Rent, Real Property Taxes, insurance premiums,


                                       11
<PAGE>   12
and other charges, if any, payable by Lessee hereunder for the period during
which such damage, its repair or the restoration continues (not to exceed the
period for which rental value insurance is required under Paragraph 8.3(b)),
shall be abated in proportion to the degree to which Lessee's use of the
Premises is impaired. Except for abatement of Base Rent, Real Property Taxes
insurance premiums, and other charges, if any, as aforesaid, all other
obligations of Lessee hereunder shall be performed by Lessee, and Lessee shall
have no claim against Lessor for any damage suffered by reason of any such
repair or restoration.

                  (b) If Lessor shall be obligated to repair or restore the
Premises under the provisions of this Paragraph 9 and shall not commence, in a
substantial and meaningful way, the repair or restoration of the Premises 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 to Lessor and such Lenders
and such repair or restoration is not commenced within thirty (30) days after
receipt of such notice, this Lease shall terminate as of the date specified in
said notice. If Lessor or a Lender commences the repair or restoration of the
Premises within thirty (30) days aver receipt of such police, this Lease shall
continue in full force and effect. "Commence" as used in this Paragraph 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 HAZARDOUS SUBSTANCE CONDITIONS. If a Hazardous Substance Condition
occurs, unless Lessee is legally responsible therefor (in which case Lessee
shall make the investigation and remediation thereof required by Applicable Law
and this Lease shall continue in full force and effect, but subject to Lessor's
rights under Paragraph 13), Lessor may at Lessor's option either (i) investigate
and remediate such Hazardous Substance Condition, it required, as soon as
reasonably possible at Lessors expense, in which event this Lease shall continue
in full force and effect, or (ii) if the estimated cost to investigate and
remediate such condition exceeds twelve (12) times the then monthly Base Rent or
$100,000, whichever is greater, give written notice to Lessee within thirty (30)
days after receipt by Lessor of knowledge of the occurrence of such Hazardous
Substance Condition of Lessor's desire to terminate this Lease as of the date
sixty (60) days following the giving of such notice. In the event Lessor elects
to give such notice of Lessor's intention to terminate this Lease, Lessee shall
have the right within ten (10) days after the receipt of such notice to give
written notice to Lessor of Lessee's commitment to pay for the investigation and
remediation of such Hazardous Substance Condition totally at Lessee's expense
and without reimbursement from Lessor except to the extent of an amount equal to
twelve (12) times the then monthly Base Rent or $100,000, whichever is greater.
Lessee shall provide Lessor with the funds required of Lessee or satisfactory
assurance thereof within thirty (30) days following Lessee's said commitment. In
such event this Lease shall continue in full force and effect, and Lessor shall
proceed to make such investigation and remediation as soon as reasonably
possible and the required funds are available. If Lessee does not give such
notice and provide the required funds or assurance thereof within the times
specified above, this Lease shall terminate as of the dale specified in Lessor's
notice of termination. If a Hazardous Substance Condition occurs for which
Lessee is not legally responsible, there shall be abatement of Lessee's
obligations under this Lease to the same extent as provided in Paragraph 9.6(a)
for a period of not to exceed twelve months.

         9.8 TERMINATION--ADVANCE PAYMENTS. Upon termination of this Lease
pursuant to this 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 under the terms
of this Lease.

         9.9 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.  SEE ADDENDUM #60

         10.1 (a) PAYMENT OF TAXES. Lessee shall pay the Real Property Taxes, as
defined in Paragraph 10.2, applicable to the Premises during the term of this
Lease. Subject to Paragraph 10.1(b), all such payments shall be made at least
ten (10) days prior to the delinquency date of the applicable installment.
Lessee shall promptly furnish Lessor with satisfactory evidence that such taxes
have been paid. If any such taxes to be paid by Lessee shall cover any period of
time prior to or after the expiration or earlier termination of the term hereof,
Lessee's share of such taxes shall be equitably prorated to cover only the
period of time within the tax fiscal year this Lease is in effect, and Lessor
shall reimburse Lessee for any overpayment after such proration. If Lessee shall
fail to pay any Real Property Taxes required by this Lease to be paid by Lessee,
Lessor shall have the right to pay the same, and Lessee shall reimburse Lessor
therefor upon demand.

                  (b) ADVANCE PAYMENT. In order to insure payment when due and
before delinquency of any or all Real Property Taxes, Lessor reserves the right,
at Lessor's option, to estimate the current Real Property Taxes applicable to
the Premises, and to require such current year's Real Property Taxes to 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.

         10.2 DEFINITION OF "REAL PROPERTY TAXES." As used herein, the term
"REAL PROPERTY TAXES" shall include any form of real estate tax or assessment,
general, special, ordinary or extraordinary, and any license fee, commercial
rental tax, improvement bond or bonds, levy or tax (other than inheritance,
personal income or estate taxes) imposed upon the Premises by any authority
having the direct or indirect power to tax, including any city, state or federal
government, or any school, agricultural, sanitary, fire, street, drainage or
other improvement district thereof, levied against any legal or equitable
interest of Lessor in the Premises or in the real property of which the Premises
are a part, Lessor's right to rent or other income therefrom, and/or Lessor's
business of leasing the Premises. 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, or changes in applicable law taking
effect, during the term of this Lease, including but not limited to a change in
the ownership of the Premises or in the improvements thereon, the execution of
this Lease, or any modification, amendment or transfer thereof, and whether or
not contemplated by the Parties.

         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 determined by Lessor from the respective valuations
assigned in the assessors work sheets or such other information as may be
reasonably available. Lessor's reasonable determination thereof, in good faith
shall be conclusive.

         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 contained in the Premises or elsewhere. When ______________________
shall cause its Trade Fixtures, furnishings, equipment and all other personal
property to be assessed and billed separately from the real property of Lessor.
If any of Lessee's said personal property shall be assessed with Lessor's real
property, Lessee shall pay Lessor the taxes attributable to Lessee within ten
(10) days after receipt of a written statement setting forth the taxes
applicable to Lessee's property or, at Lessor's option, as provided in Paragraph
10.1(b).

11.      UTILITIES. Lessee shall pay for all water, gas, heal, 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 with other premises.

12.      ASSIGNMENT AND SUBLETTING.

         12.1 LESSOR'S CONSENT REQUIRED. SEE ADDENDUM #61

                  (a) Lessee shall not voluntarily or by operation of law
assign, transfer, mortgage or otherwise transfer or encumber (collectively,
"ASSIGNMENT") or sublet all or any part of Lessee's interest in this Lease or in
the Premises without Lessor's prior written consent given under and subject to
the terms of Paragraph 36.

                  (b) A change in the control of Lessee shall constitute an
assignment requiring Lessor's consent. The transfer, on a cumulative basis, of
twenty-five percent (25%) or more of the voting control of Lessee shall
constitute a change in control for this purpose.

                  (c) The involvement of Lessee or its assets in any
transaction, or series of transactions (by way of merger, sale, acquisition,
financing, refinancing, transfer, leveraged buy-out or otherwise), whether or
not a formal assignment or hypothecation of this Lease or Lessee's assets
occurs, which results or will result in a reduction of the Net Worth of Lessee,
as hereinafter defined, by an amount equal to or greater than twenty-five
percent (25%) of such Net Worth of Lessee as it was represented to Lessor at the
time of the execution by Lessor of this Lease or at the time of the most recent
assignment to which Lessor has consented, or as it exists immediately prior to
said transaction or transactions constituting such reduction, at whichever time
said Net Worth of Lessee was or is greater, shall be considered an assignment of
this Lease by Lessee to which Lessor may reasonably withhold its consent. "Net
Worth of Lessee" for purposes of this Lease shall be the net worth of Lessee
(excluding any guarantors) established under generally accepted accounting
principles consistently applied.

                  (d) An assignment or subletting of Lessee's interest in this
Lease without Lessor's specific prior written 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 unconsented to assignment or subletting as a nondurable Breach, Lessor
shall have the right to either: (i) terminate this Lease, or (ii) upon thirty
(30) days written notice ("Lessor's Notice"), increase the monthly Base Rent to
fair market rental value or one hundred ten percent (110%) of the Base Rent then
in effect, whichever is greater. Pending determination of the new fair market
rental value, if disputed by Lessee, Lessee shall pay the amount set forth in
Lessor's Notice, with any overpayment credited against the next installment(s)
of Base Rent coming due, and any underpayment for the period retroactively to
the effective date of the adjustment being due and payable immediately upon the
determination thereof. Further, in the event of such Breach and market value
adjustment, (i) the purchase price of any option to purchase the Premises held
by Lessee shall be subject to similar adjustment to the then fair market value
(without the Lease being considered an encumbrance or any deduction for
depreciation or obsolescence, and considering the Premises at its highest and
best use and in good condition), or one hundred ten percent (110%) of the price
previously in effect, whichever is greater, (ii) any index-oriented rental or
price adjustment formulas contained in this Lease shall be adjusted to require
that the base index be determined with reference to the index applicable to the
time of such adjustment, and (iii) any fixed rental adjustments scheduled during
the remainder of the Lease term shall be increased in the same ratio as the new
market rental bears to the Base Rent in effect immediately prior to the market
value adjustment.

         12.2 TERMS AND CONDITIONS APPLICABLE TO ASSIGNMENT AND SUBLETTING. SEE
ADDENDUM #62

                  (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 Base Rent and other sums due Lessor
hereunder or for the performance of any other obligations to be performed by
Lessee under this Lease.

                  (b) Lessor may accept any 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 any rent or performance shall constitute a waiver or
estoppel of Lessor's right


                                       14
<PAGE>   15
to exercise its remedies for the Default or Breach by Lessee of any of the
terms, covenants or conditions of this Lease.

                  (c) The consent of Lessor to any assignment or subletting
shall not constitute a consent to any subsequent assignment or subletting by 
Lessee or to any subsequent or successive assignment or subletting by the 
sublessee.

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

                  (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 non-refundable deposit of $1,000 or ten percent (10%) of the
current monthly Base Rent, whichever is greater, as reasonable consideration for
Lessor's considering and processing the request for consent. Lessee agrees to
provide Lessor with such other or additional information and/or documentation as
may be reasonably requested by Lessor.

                  (f) Any assignee of, or sublessee under, this Lease shall, by
reason of accepting such assignment or entering into such sublease, be deemed,
for the benefit of Lessor, 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 in writing.

                  (g) The occurrence of a transaction described in Paragraph
12.1(c) shall give Lessor the right (but not the obligation) to require that the
Security Deposit be increased to an amount equal to six (6) times the then
monthly Base Rent, and Lessor may make the actual receipt by Lessor of the
amount required to establish such Security Deposit a condition to Lessor's
consent to such transaction.

         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 rentals and income arising from any sublease of all or
a portion of the Premises heretofore or hereafter made by Lessee, and Lessor may
collect such rent and income and apply same toward Lessee's obligations under
this Lease; provided, however, that until a Breach (as defined in Paragraph
13.1) shall occur in the performance of Lessee's obligations under this Lease,
Lessee may, except as otherwise provided in this Lease, receive, collect and
enjoy the rents accruing under such sublease. Lessor shall not, by reason of
this or any other assignment of such sublease to Lessor, nor by reason of the
collection of the rents from a sublessee, be deemed liable to the sublessee for
any failure of Lessee to perform and comply with any of Lessee's obligations to
such sublessee under such sublease. Lessee hereby irrevocably authorizes and
directs any such sublessee, upon receipt of a written notice from Lessor stating
that a Breach exists in the performance of Lessee's obligations under this
Lease, to pay to Lessor the rents and other charges due and to become due under
the sublease. Sublessee shall rely upon any such statement and request from
Lessor and shall pay such rents and other charges to Lessor without any
obligation or right to inquire as to whether such Breach exists and
notwithstanding any notice from or claim from Lessee to the contrary. Lessee
shall have no right or claim against said sublessee or, until the Breach has
been cured, against Lessor, for any such rents and other charges so paid by said
sublessee to Lessor.

                  (b) In the event of a Breach by Lessee in the performance of
its obligations under this Lease, Lessor, at its option and without any
obligation to do so, may require any sublessee to attorn to Lessor, in which
event Lessor shall undertake the obligations of the sublessor under such
sublease from the time of the exercise of


                                       15
<PAGE>   16
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 other prior Defaults or Breaches of such sublessor
under such sublease.

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

                  (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, it 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.  SEE ADDENDUM # 63

         13.1 DEFAULT; BREACH. Lessor and Lessee agree that if an attorney is
consulted by Lessor in connection with a Lessee Default or Breach (as
hereinafter defined), $350.00 is a reasonable minimum sum per such occurrence
for legal services and costs in the preparation and service of a notice of
Default, and that Lessor may include the cost of such services and costs in said
notice as rent due and payable to cure said Default. A "DEFAULT" is defined as a
failure by the Lessee to observe, comply with or perform any of the terms,
covenants, conditions or rules applicable to Lessee under this Lease. A "BREACH"
is defined as the occurrence of any one or more of the following Defaults, and,
where a grace period for cure after notice is specified herein, the failure by
Lessee to cure such Default prior to the expiration of the applicable grace
period, and shall entitle Lessor to pursue the remedies set forth in Paragraphs
13.2 and/or 13.3:

                  (a) The abandonment of the Premises.

                  (b) Except as expressly otherwise provided in this Lease, the
failure by Lessee to make any payment of Base Rent or any other monetary payment
required to be made by Lessee hereunder, whether to Lessor or to a third party,
as and when due, the failure by Lessee to provide Lessor with reasonable
evidence of insurance or surety bond required under this Lease, or the failure
of Lessee to fulfill any obligation under this Lease which endangers or
threatens life or property, where such failure continues for a period of three
(3) days following written notice thereof by or on behalf of Lessor to Lessee.

                  (c) Except as expressly otherwise provided in this Lease, the
failure by Lessee to provide Lessor with reasonable written evidence (in duly
executed original form, it applicable) of (i) compliance with applicable law per
Paragraph 6.3, (ii) the inspection, maintenance and service contracts required
under Paragraph 7.1(b), (iii) the recission of an unauthorized assignment or
subletting per Paragraph 12.1(b), (iv) a Tenancy Statement per Paragraphs 16 or
37, (v) the subordination or non-subordination of this Lease per Paragraph 30,
(vi) the guaranty of the performance of Lessee's obligations under this Lease if
required under Paragraphs 1.11 and 37, (vii) the execution of 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 by or on behalf of Lessor 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,
that are to be observed, complied with or performed by Lessee, other than those
described in subparagraphs (a), (b) or (c), above, where such Default continues
for a period of thirty (30) days after written notice thereof by or on behalf of
Lessor to Lessee; provided, however, that if the nature of Lessee's Default is
such that more than thirty (30) days are reasonably required for its cure, then
it shall not be deemed to be a Breach of this Lease by Lessee if Lessee
commences such cure within said thirty (30) day period and thereafter diligently
prosecutes such cure to completion.


                                       16
<PAGE>   17
                  (e) The occurrence of any of the following events: (i) The
making by Lessee of any general arrangement or assignment for the benefit of
creditors; (ii) Lessee's 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 (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 by Lessor that any financial statement given
to Lessor by Lessee or any Guarantor of Lessee's obligations hereunder was
materially false.

         13.2 REMEDIES. If Lessee fails to perform any affirmative duty or
obligation of Lessee under this Lease, within ten (10) days after written notice
to Lessee (or in case of an emergency, without notice), Lessor may at its option
(but without obligation to do so), 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 to Lessor upon 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 under this Lease by Lessee to be made
only by cashier's check. In the event of a Breach of this Lease by Lessee, as
defined in Paragraph 13.1, 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, Lessor may:

                  (a) Terminate Lessee's right to possession of the Premises by
any lawful means, in which case this Lease and the term hereof shall terminate
and Lessee shall immediately surrender possession of the Premises to Lessor. In
such event Lessor shall be entitled to recover from Lessee: (i) the worth at the
time of the award of 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 the leasing commission paid by Lessor 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 prior sentence shall be computed by discounting such
amount at the discount rate of the Federal Reserve Bank of San Francisco at the
time of award plus one percent. Efforts by Lessor to mitigate damages caused by
Lessee's Default or Breach of this Lease shall not waive Lessor's right to
recover damages under this Paragraph. If termination of this Lease is obtained
through the provisional remedy of unlawful detainer, Lessor shall have the right
to recover in such proceeding the unpaid rent and damages as are recoverable
therein, or Lessor may reserve therein the right to recover all or any part
thereof in a separate suit for such rent and/or damages. If a notice and grace
period required under subparagraphs 13.1(b), (c) or (d) was not previously
given, a notice to pay rent or quit, or to perform or quit, as the case may be,
given to Lessee under any statute authorizing the forfeiture of leases for
unlawful detainer shall also constitute the applicable notice for grace period
purposes required by subparagraphs 13.1(b), (c) or (d). In such case, the
applicable grace period under subparagraphs 13.1(b), (c) or (d) and under the
unlawful detainer statute shall run concurrently after the one such statutory
notice, 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.




                                       17
<PAGE>   18
                  (b) Continue the Lease and Lessee's right to possession in
effect (in California under California Civil Code Section 1951.4) after Lessee's
Breach and abandonment and recover the rent as it becomes due, provided Lessee
has the right to sublet or assign, subject only to reasonable limitations. See
Paragraphs 12 and 36 for the limitations on assignment and subletting which
limitations Lessee and Lessor agree are reasonable. Acts of maintenance or
preservation, efforts to relet the Premises, or the appointment of a receiver to
protect the Lessor's interest under the Lease, shall not constitute a
termination of the Lessee's right to possession.

                  (c) Pursue any other remedy now or hereafter available to
Lessor under the laws or judicial decisions of the state wherein the Premises
are located.

                  (d) The expiration or termination of this Lease and/or the
termination of Lessee's right to possession shall not relieve Lessee from
liability under any indemnity provisions of this Lease as to matters occurring
or accruing during the term hereof or by reason of Lessee's occupancy of the
Premises.

         13.3 INDUCEMENT RECAPTURE IN EVENT OF BREACH. Any agreement by Lessor
for free or abated rent or other charges applicable to the Premises, or for the
giving or paying by Lessor to or for Lessee of any cash or other bonus,
inducement or consideration for Lessee's entering into this Lease, all of which
concessions are hereinafter referred to as "INDUCEMENT PROVISIONS" shall be
deemed conditioned upon Lessee's full and faithful performance of all of the
terms, covenants and conditions of this Lease to be performed or observed by
Lessee during the term hereof as the same may be extended. Upon the occurrence
of a Breach of this Lease by Lessee, as defined in Paragraph 13.1, any such
Inducement Provision shall automatically be deemed deleted from this Lease and
of no further force or effect, and any rent, other charge, bonus, Inducement or
consideration theretofore abated, given or paid by Lessor under such an
Inducement Provision shall be immediately due and payable by Lessee to Lessor,
and recoverable by Lessor as additional rent due under this Lease.

         13.4 LATE CHARGES. Lessee hereby acknowledges that late payment by
Lessee to Lessor of rent and other sums due hereunder will cause Lessor to incur
costs not contemplated by this Lease, the exact amount of which will be
extremely difficult to ascertain. Such costs include, but are not limited to,
processing and accounting charges, and late charges which may be imposed upon
Lessor by the terms of any ground lease, mortgage or trust deed covering the
Premises. Accordingly, if any installment of rent or any other sum due from
Lessee shall not be received by Lessor or Lessor's designee within ten (10) days
after such amount shall be due, then, without any requirement for notice to
Lessee, Lessee shall pay to Lessor a late charge equal to six percent (6%) of
such overdue amount. The parties hereby agree that such late charge represents a
fair and reasonable estimate of the costs Lessor will incur by reason of late
payment by Lessee. Acceptance of such date charge by Lessor shall in no event
constitute a waiver of Lessee's Default or Breach with respect to such overdue
amount, nor prevent Lessor from exercising 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 Paragraph 4.1 or any other provision of this Lease to the
contrary, Base Rent shall, at Lessor's option, become due and payable quarterly
in advance.

         13.5 BREACH BY LESSOR. 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 13.5, a
reasonable time shall in no event be less than thirty (30) days after receipt by
Lessor, and by the holders of any ground lease, mortgage or deed of trust
covering the Premises 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 after such notice
are reasonably required for its performance, then Lessor shall not be in breach
of this Lease if performance is commenced within such thirty (30) day period and
thereafter diligently pursued to completion.

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 (all of which are herein called "CONDEMNATION"), this Lease shall
terminate as to the part so taken as of the date the condemning authority takes
title or possession, whichever first occurs. If more than ten percent (10%) of
the floor area of the Premises, or more than twenty-five percent (25%)


                                       18
<PAGE>   19
of the land area not occupied by any building, is taken by condemnation, Lessee
may, at Lessee's option, to be exercised in writing within ten (10) days after
Lessor shall have given Lessee written notice of such taking (or in the absence
of such notice, within ten (10) days after the condemning authority shall have
taken possession) terminate this Lease as of the date the condemning authority
takes such possession. If Lessee does not terminate this Lease in accordance
with the foregoing, this Lease shall remain in full force and effect as to the
portion of the Premises remaining, except that the Base Rent shall be reduced in
the same proportion as the rentable floor area of the Premises taken bears to
the total rentable floor area of the building located on the Premises. No
reduction of Base Rent shall occur if the only portion of the Premises taken is
land on which there is no building. Any award for the taking of all or any part
of the Premises under the power of eminent domain or any payment made under
threat of the exercise of such power shall be the property of Lessor, whether
such award shall be made as compensation for diminution in value of the
leasehold or for the taking of the fee, or as severance damages, provided,
however, that Lessee shall be entitled to any compensation, separately awarded
to Lessee for Lessee's relocation expenses and/or loss of Lessee's Trade
Fixtures. In the event that this Lease is not terminated by reason of such
condemnation, Lessor shall to the extent of its net severance damages received,
over and above the legal and other expenses incurred by Lessor in the
condemnation matter, repair any damage to the Premises caused by such
condemnation, except to the extent that Lessee has been reimbursed therefor by
the condemning authority. Lessee shall be responsible for the payment of any
amount in excess of such net severance damages required to complete such repair.

15.      BROKER'S FEE.

         15.1 The Brokers named in Paragraph 1.10 are the procuring causes of
this Lease.

         15.2 Upon execution of this Lease by both Parties, Lessor shall pay to
said Brokers jointly, or in such separate shares as they may mutually designate
in writing, a fee as set forth in a separate written agreement between Lessor
and said Brokers (or in the event there is no separate written agreement between
Lessor and said Brokers, the sum of $_____________) for brokerage services
rendered by said Brokers to Lessor in this transaction.

         15.3 Unless Lessor and Brokers have otherwise agreed in writing, Lessor
further agrees that: (a) if Lessee exercises any Option (as defined in Paragraph
39.1) or any Option subsequently granted which is substantially similar to an
Option granted to Lessee in this Lease, or (b) if Lessee acquires any rights to
the Premises or other premises described in this Lease which are substantially
similar to what Lessee would have acquired had an Option herein granted to
Lessee been exercised, or (c) if Lessee remains in possession of the Premises,
with the consent of Lessor, after the expiration of the term of this Lease after
having failed to exercise an Option, or (d) if said Brokers are the procuring
cause of any other lease or sale entered into between the Parties pertaining to
the Premises and/or any adjacent property in which Lessor has an interest, or
(e) if Base Rent is increased, whether by agreement or operation of an
escalation clause herein, then as to any of said transactions, Lessor shall pay
said Brokers a fee in accordance with the schedule of said Brokers in effect at
the time of the execution of this Lease.

         15.4 Any buyer or transferee of Lessor's interest in this Lease,
whether such transfer is by agreement or by operation of law, shall be deemed to
have assumed Lessor's obligation under this Paragraph 15. Each Broker shall be a
third party beneficiary of the provisions of this Paragraph 15 to the extent of
its interest in any commission arising from this Lease and may enforce that
right directly against Lessor and its successors.

         15.5 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 named in Paragraph 1.10) in connection with the negotiation of
this Lease and/or the consummation of the transaction contemplated hereby, and
that no broker or other person, firm or entity other than said named Brokers is
entitled to any commission or finder's fee in connection with said transaction.
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, attorneys' fees reasonably incurred with respect thereto.


                                       19
<PAGE>   20
         15.6 Lessor and Lessee hereby consent to and approve all agency
relationships, including any dual agencies, indicated in Paragraph 1.10.

16.      TENANCY STATEMENT.

         16.1 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 "TENANCY STATEMENT" 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.

         16.2 Lessor desires to finance, refinance, or sell the Premises, any
part thereof, or the building of which the Premises are a part, Lessee and all
Guarantors of Lessee's performance hereunder shall deliver to any potential
lender or purchaser designated by Lessor such financial statements of Lessee and
such Guarantors 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.      LESSOR'S LABILITY. 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 in this Lease,
Lessor shall deliver to the transferee or assignee (in cash or by credit) any
unused Security Deposit held by Lessor at the time of such transfer or
assignment. Except as provided in Paragraph 15, upon such transfer or assignment
and delivery of the Security Deposit, as aforesaid, the prior Lessor shall be
relieved of all liability with respect to the obligations and/or covenants under
this Lease thereafter to be performed by the Lessor. Subject to the foregoing,
the obligations and/or covenants in this Lease to be performed by the Lessor
shall be binding only upon the Lessor as hereinabove defined.

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.      INTEREST ON PAST-DUE OBLIGATIONS. Any monetary payment due Lessor
hereunder, other than late charges, not received by Lessor within thirty (30)
days following the date on which it was due, shall bear interest from the
thirty-first (31st) day after it was due at the rate of 12% per annum, but not
exceeding the maximum rate allowed by law, in addition to the late charge
provided for in Paragraph 13.4.

20.      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.

21.      RENT DEFINED. All monetary obligations of Lessee to Lessor under the
terms of this Lease are deemed to be rent.

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.

23.      NOTICES.

         23.1 All notices required or permitted by this Lease shall be in
writing and may be delivered in person (by hand or by messenger or courier
service) or may be sent by regular, codified 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 notice purposes. Either
Party may by written notice to the other specify a different address for notice
purposes, except that upon Lessee's taking possession of the Premises, the
Premises shall constitute Lessee's address for the purpose of mailing or
delivering notices to Lessee. A copy of all notices required or permitted to be
given to Lessor hereunder shall be concurrently transmitted to such party or
parties at such addresses as Lessor may from time to time hereafter designate by
written notice to Lessee.

         23.2 Any notice sent by registered or certified mail, return receipt
requested, shall be deemed given on the date of delivery shown on the receipt
card, or if no delivery date is shown, the postmark thereon. If sent by regular
mail the notice shall be deemed given forty-eight (48) hours after the same is
addressed as required herein and mailed with postage prepaid. Notices delivered
by United States Express Mail or overnight courier that guarantees next day
delivery shall be deemed given twenty-four (24) hours after delivery of the same
to the United States Postage Service or courier. If any notice is transmitted by
facsimile transmission or similar means, the same shall be deemed served or
delivered upon telephone confirmation of receipt of the transmission thereof,
provided a copy is also delivered via delivery or mail. If notice is received on
a Sunday or legal holiday, it shall be deemed received on the next business day.

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

25.      RECORDING. Either Lessor or Lessee shall, upon request of the other,
execute, acknowledge and deliver to the other a short form memorandum of this
Lease for recording purposes. The Party requesting recordation shall be
responsible for payment of any fees or taxes 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 earlier termination of
this Lease.

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. All provisions of this Lease to be observed
or performed by Lessee are both covenants and conditions.

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 by Lessor upon the real property of which the Premises are a
part, to any and all advances made on the security thereof, and to all renewals,
modifications, consolidations, replacements and extensions thereof. Lessee
agrees that the Lenders holding any such Security Device shall have no duty,
liability or obligation to perform any of the obligations of Lessor under this
Lease, but that in the event of Lessor's default with respect to any such
obligation, Lessee will give any Lender whose name and address have been
furnished Lessee in writing for such purpose notice of Lessor's default and
allow such Lender thirty (30) days following receipt of such notice for the cure
of said default before invoking any remedies Lessee may have by reason thereof.
If any Lender shall elect to have this Lease and/or any Option granted hereby
superior to the lien of its Security Device and shall give written notice
thereof to Lessee, 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 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 assurance (a "NON-DISTURBANCE AGREEMENT") from the
Lender that Lessee's possession 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.

         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
such subordination or non-subordination, attornment and/or non-disturbance
agreement as is provided for herein.

31.      ATTORNEY'S FEES. If any Party or Broker brings an action or proceeding
to enforce the terms hereof or declare rights hereunder, the Prevailing Party
(as hereafter defined) or Broker in any such proceeding, action, or appeal
thereon, shall be entitled to reasonable attorney's 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 attorney's fee award shall not be computed in accordance
with any court fee schedule, but shall be such as to fully reimburse all
attorney's fees reasonably incurred. Lessor shall be entitled to attorney's
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 or to the building of which
they are a part, as Lessor may reasonably deem necessary. Lessor may at any time
place on or about the Premises or building any ordinary "For Sale" signs and
Lessor may




                                       22
<PAGE>   23
at any time during the last one hundred twenty (120) days of the term hereof
place on or about the Premises any ordinary "For Lease" signs. All such
activities of Lessor shall be without abatement of rent or liability to Lessee.

33.      AUCTIONS. Lessee shall not conduct, nor permit to be conducted, either
voluntarily or involuntarily, any auction upon the Premises without first having
obtained Lessor's prior written consent. Notwithstanding anything to the
contrary in this Lease, Lessor shall not be obligated to exercise any standard
of reasonableness in determining whether to grant such consent.

34.      SIGNS. Lessee shall not place any sign upon the Premises, except that
Lessee may, with Lessor's prior written consent, install (but not on the roof)
such signs as are reasonably required to advertise Lessee's own business. The
installation of any sign on the Premises by or for Lessee shall be subject to
the provisions of Paragraph 7 (Maintenance, Repairs, Utility Installations,
Trade Fixtures and Alterations).

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, Lessor shall, in the event of any such surrender,
termination or cancellation, have the option to continue any one or all of any
existing subtenancies. Lessor's failure within ten (10) days following any such
event to make a written election 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.

                  (a) Except for Paragraph 33 hereof (Auctions) or 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' or other consultants' fees)
incurred in the consideration of, or response to, a request by Lessee for any
Lessor consent pertaining to this Lease or the Premises, including but not
limited to consents to an assignment, a subletting or the presence or use of a
Hazardous Substance, practice or storage tank, shall be paid by Lessee to Lessor
upon receipt of an invoice and supporting documentation therefor. Subject to
Paragraph 12.2(e) (applicable to assignment or subletting), Lessor may, as a
condition to considering any such request by Lessee, require that Lessee deposit
with Lessor an amount of money (in addition to the Security Deposit held under
Paragraph 5) reasonably calculated by Lessor to represent the cost Lessor will
incur in considering and responding to Lessee's request. Except as otherwise
provided, any unused portion of said deposit shall be refunded to Lessee without
interest. Lessor's consent to any act, assignment of this Lease or subletting of
the Premises by Lessee 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.

                  (b) All conditions to Lessor's consent authorized by this
Lease are acknowledged by Lessee as being reasonable. 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.

37.      GUARANTOR.

         37.1 If there are to be any Guarantors of this Lease per Paragraph
1.11, the form of the guaranty to be executed by each such Guarantor shall be in
the form most recently published by the American Industrial Real Estate
Association, and each said Guarantor shall have the same obligations as Lessee
under this Lease, including but not limited to the obligation to provide the
Tenancy Statement and information called for by Paragraph 16.

         37.2 It shall constitute a Default of the Lessee under this Lease if
any such Guarantor fails or refuses, upon reasonable request by Lessor to give:
(a) evidence of the due execution of the guaranty called for by this


                                       23
<PAGE>   24
Lease, including the authority of the Guarantor (and of the party signing on
Guarantor's behalf) to obligate such Guarantor on said guaranty, and including
in the case of a corporate Guarantor, a certified copy of a resolution of its
board of directors authorizing the making of such guaranty, together with a
certificate of incumbency showing the signatures of the persons authorized to
sign on its behalf, (b) current financial statements of Guarantor as may from
time to time be requested by Lessor, (c) a Tenancy Statement, or (d) written
confirmation that the guaranty is still in effect.

38.      QUIET POSSESSION. Upon payment by Lessee of the rent for the Premises
and the observance and performance of all of the covenants, conditions and
provisions on Lessee's part to be observed and performed under this Lease,
Lessee shall have quiet possession of the Premises for the entire term hereof
subject to all of the provisions of this Lease.

39.      OPTIONS.

         39.1 DEFINITION. As used in this Paragraph 39 the word "OPTION" has the
following meaning: (a) the right to extend the term of this Lease or to renew
this Lease or to extend or renew any lease that Lessee has on other property of
Lessor; (b) the right of first refusal to lease the Premises or the right of
first offer to lease the Premises or the right of first refusal to lease other
property of Lessor or the right of first offer to lease other property of
Lessor; (c) the right to purchase the Premises, or the right of first refusal to
purchase the Premises, or the right of first offer to purchase the Premises, or
the right to purchase other property of Lessor, or the right of first refusal to
purchase other property of Lessor, or the right of first offer to purchase other
property of Lessor.

         39.2 OPTIONS PERSONAL TO ORIGINAL LESSEE. Each Option granted to Lessee
in this Lease is personal to the original Lessee named in Paragraph 1.1 hereof,
and cannot be voluntarily or involuntarily assigned or exercised by any person
or entity other than said original Lessee while the original Lessee is in full
and actual possession of the Premises and without the intention of thereafter
assigning or subletting. The Options, if any, herein granted to Lessee are not
assignable, either as a part of an assignment of this Lease or separately or
apart therefrom, and no Option may be separated from this Lease in any manner,
by reservation or otherwise.

         39.3 MULTIPLE OPTIONS. In the event that Lessee has any multiple
Options to extend or renew this Lease, a later option cannot be exercised unless
the prior Options to extend or renew this Lease have been validly exercised.

         39.4 EFFECT OF DEFAULT ON OPTIONS.

                  (a) Lessee shall have no right to exercise an Option,
notwithstanding any provision in the grant of Option to the contrary: (i) during
the period commencing with the giving of any notice of Default under Paragraph
13.1 and continuing until the noticed Default is cured, or (ii) during the
period of time any monetary obligation due Lessor from Lessee is unpaid (without
regard to whether notice thereof is given Lessee), or (iii) during the time
Lessee is in Breach of this Lease, or (iv) in the event that Lessor has given to
Lessee three (3) or more notices of Default under Paragraph 13.1, 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) All rights of Lessee under the provisions of an Option
shall terminate and be of no further force or effect, notwithstanding Lessee's
due and timely exercise of the Option, if, after such exercise and during the
term of this Lease, (i) Lessee fails to pay to Lessor a monetary obligation of
Lessee for a period of thirty (30) days after such obligation becomes due
(without any necessity of Lessor to give notice thereof to Lessee), or (ii)
Lessor gives to Lessee three or more notices of Default under Paragraph 13.1
during any twelve month period, whether or not the Defaults are cured, or (iii)
if Lessee commits a Breach of this Lease.




                                       24
<PAGE>   25
40.      MULTIPLE BUILDINGS. If the Premises are part of a group of buildings
controlled by Lessor, Lessee agrees that it will abide by, keep and observe all
reasonable rules and regulations which Lessor may make from time to time for the
management, safety, care, and cleanliness of the grounds, the parking and
unloading of vehicles and the preservation of good order, as well as for the
convenience of other occupants or tenants of such other buildings and their
invitees, 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. 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 under the
provisions of this Lease.

44.      AUTHORITY. If either Party hereto is a corporation, trust, or general
or limited partnership, 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. If Lessee is a corporation, trust or
partnership, Lessee shall, within thirty (30) days after request by Lessor,
deliver to Lessor evidence satisfactory to Lessor of such authority.

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

46.      OFFER. Preparation of this Lease by Lessor or Lessor's agent and
submission of same to Lessee shall not be deemed an offer to lease to Lessee.
This Lease is not intended to be binding until executed by all Parties hereto.

47.      AMENDMENTS. This Lease may be modified only in writing, signed by the
parties in interest at the time of the modification. The parties shall amend
this Lease from time to time to reflect any adjustments that are made to the
Base Rent or other rent payable under this Lease. As long as they do not
materially change Lessee's obligations hereunder, Lessee agrees to make such
reasonable non-monetary modifications to this Lease as may be reasonably
required by an institutional, insurance company, or pension plan Lender in
connection with the obtaining of normal financing or refinancing of the property
of which the Premises are a part.

48.      MULTIPLE PARTIES. Except as otherwise expressly provided herein, if
more than one person or entity is named herein as either Lessor or Lessee, the
obligations of such multiple parties shall be the joint and several
responsibility of all persons or entitles named herein as such Lessor or Lessee.

                   ADDENDUM TO STANDARD INDUSTRIAL/COMMERCIAL
                             SINGLE TENANT LEASE-NET
                             DATED NOVEMBER 20, 1992
                                 BY AND BETWEEN
         ROSSMORE ENTERPRISES, A CALIFORNIA CORPORATION AS "LESSOR" AND
                         MEADE INSTRUMENTS CORPORATION,
                      A CALIFORNIA CORPORATION AS "LESSEE"




This LEASE ADDENDUM ("Addendum") is attached to, made a part of, incorporated
into and amends and supplements that certain Standard Industrial/Commercial
Single-Tenant Lease - Net ("the Lease") entered into as of the 20th day of
November, 1992 by and between ROSSMORE ENTERPRISES, A California Corporation
("Lessor"), and MEADE INSTRUMENTS CORPORATION, A California Corporation
("Lessee"). Lessor and Lessee agree that notwithstanding anything contained in
the Lease to the contrary, the provisions set forth in this Addendum will be
deemed to be a part of the Lease and will supersede any contrary provision in
the Lease and prevail and control for all purposes. It is the intention of the
parties that the use of this Addendum will eliminate for the most part the need
to strike through and interlineate portions of the Lease in order to reflect the
changes to the Lease desired by the parties as set forth in this Addendum. All
references to the Lease and in this Addendum to "Lease" are to be construed to
mean the Lease as amended and supplemented by this Addendum, have the same
meaning as the terms used in the Lease.

         49. PARAGRAPH 3.1 OPTION TO EXTEND TERM. Notwithstanding anything to
the contrary contained in Paragraphs 1.3, 3.1 or elsewhere in the Lease, subject
to the terms of Paragraph 39 of the Lease, Lessor hereby grants Lessee a one
time option to extend the Term ("Option to Extend") for an additional period of
five (5) years ("Option Period"). Such right shall apply only to Lessee's entire
Premises, shall be for a term that shall begin immediately following Lessee's
initial Term and shall be exercised by Lessee by giving written notice to Lessor
at lease nine (9) months prior to the expiration of the initial Term. If Lessee
exercises its Option to Extend the Term, Lessee shall continue to lease the
Premises for such extended period upon the same terms and conditions set forth
in this Lease except that the Base Rent payable by Lessee to Lessor during the
Option Period shall be at 95% of the prevailing fair market rental rate for the
Premises based upon the prevailing fair market rental rate for similar space in
similar industrial buildings within the vicinity of the building. Lessor shall
provide Lessee with written notice of the fair market rental rate for the
Premises, not later than thirty (30) days following receipt of Lessee's exercise
notice. Lessee shall have twenty (20) days ("Lessee's Review Period") after
receipt of Lessor's notice of the fair market rental rate within which to accept
such fair market rental rate or to reasonable object thereto in writing. If
Lessee objects to the fair market rental rate submitted by Lessor, Lessor and
Lessee shall attempt in good faith to agree upon such fair market rental rate,
using their best good faith efforts. If Lessor and Lessee fail to reach
agreement on such fair market rental rate within fifteen (15) days following
Lessee's Review Period (the "Outside Agreement Date") then, at Lessee's election
delivered to Lessor in writing, Lessee may either cancel its exercise of its
Option to Extend the



                                        1

Term or require that each party's determination of the fair market rental rate
for the Premises be submitted to appraisal in accordance with the following:

                  (i) Lessor and Lessee shall each appoint one appraiser who
shall, by profession, be a real estate appraiser who shall have been active over
the five (5) year period ending on the date of such appointment in the appraisal
of industrial properties in the Irvine, California area. The determination of
the appraisers shall be limited solely to the issue of whether Lessor's of
Lessee's submitted fair market rental rate for the Premises is the closest to
the actual fair market rental rate for the Premises as determined by the
appraisers, taking into account the requirements of this Item 2. Each such
appraiser shall be appointed within fifteen (15) days after the Outside
Agreement Date.

                  (ii) The two appraisers so appointed shall within fifteen (15)
days of the date of the appointment of the last appointed appraiser agree upon
and appoint a third appraiser who shall be qualified under the same criteria set
forth hereinabove for qualification of the initial two appraisers.

                  (iii) If the two appraisers are unable to agree upon a third
appraiser within fifteen (15) days, then they shall in lieu thereof each select
the names of two willing persons qualified to be appraisers hereunder and from
the four persons so named, one name shall be drawn by lot by a representative of
Lessor in the presence of a representative of Lessee, and the person whose name
is so drawn shall be the third appraiser. If either of the first two appraisers
fails to select the names of two willing appraisers and to cooperate with the
other appraiser so that a third appraiser can be selected by lot, the third
appraiser shall be selected by lot from the two appraisers which were selected
by the other appraiser for the drawing. Any vacancy in the office of the first
appraisers shall be filled by the party who initially selected that appraiser,
and if the appropriate party fails to fill any vacancy within fifteen (15) days
after such vacancy occurs, then such vacancy shall be filled by the other party.
Any vacancy in the office of the third appraiser shall be filled by the first
two appraisers in the manner specified above for the selection of a third
appraiser.

                  (iv) The three appraisers shall within thirty (30) days of the
appointment of the third appraiser reach a decision as to whether the parties
shall use Lessor's or Lessee's submitted fair market rental rate to establish
the new Base Rent for the Option Period, and shall notify Lessor and Lessee
thereof. Such decision shall be based upon the projected prevailing fair market
rentals being paid for similar industrial buildings in the Irvine, California
area.

                  (v) The decision of the majority of the three appraisers shall
be used to establish the new Base Rent for the Option Period unless either
Lessor or Lessee fails to appoint an appraiser within the time period specified
in Paragraph 3(i) hereinabove, in which event, the decision of the appraiser
appointed by one of them shall be used to establish the new Base Rent for the
Option Period.

                  (vi) Once the new Base Rent has been established, Lessee shall
have a period of five (5) days within which to either (1) accept such new Base
Rent by entering into a lease



                                        2
<PAGE>   30
amendment with Lessor which will reflect the extension of the Lease Term and the
new Base Rent, or (2) rescind its election to extend the Lease Term in which
case the Lease will terminate as of the expiration of the initial Lease Term.

                  (vii) The cost of appraisal (and, if necessary, arbitration)
shall be paid by the party against whom the decision is rendered.

                  (viii) In determining the fair market rental rate, the
appraisers shall take into account the rates charged by Lessor for other
comparable space in other buildings in the finish-out requirements imposed upon
the Lessor and shall disregard any excess over "building standard" of the
quality of the existing improvements and finish-out in the Premises. The
appraisers must be independent third parties, neither (or none) of whom may be a
present of former or prospective business partner or employee of the Lessor or
Lessee.

         50. PARAGRAPH 3.2 EARLY POSSESSION. Lessee will take early possession
on execution of the lease for purposes of tenant improvements, in conjunction
with Lessor's improvements, but that Lessee will not have beneficial occupancy
to conduct its business operations (ie., that Lessee is not liable for property
taxes, insurance, or maintenance) until March 1, 1993.

         51. PARAGRAPH 4.1 BASE RENT. Notwithstanding anything to the contrary
contained in Paragraphs 1.5, 4.1 or elsewhere in the Lease:

                  (a) Lessee shall not be required to pay monthly installments
of Base Rent for month two (2) and shall only be required to pay one-half (1/2)
of each monthly installment of Base Rent ($11,250.00) for Months Three (3)
through Twelve (12) and shall pay the Base Rent for Months Thirteen (13) through
Twenty-Four (24) ($22,500.00) of the Lease Term. Notwithstanding the foregoing,
Lessee shall pay all other amounts of additional rent including taxes and
insurance during such abated rent periods.

                  (b) On March 1, 1995, March 1, 1997 and March 1, 1999
(hereafter collectively the "Adjustment Dates"), the rent due and payable by
Lessee to Lessor hereunder shall be adjusted upward to reflect any increase in
the Consumer Price Index for all urban consumers in the Los
Angeles-Anaheim-Riverside, California area (base, 1982-1984=100), as published
in the Monthly Labor Review by the Bureau of Labor Statistics, U.S. Department
of Labor (the "Index").

Implementation of any such cost of living rent increase may be made as of or at
any time after an Adjustment Date during "Lease Year" and, if implemented after
the Adjustment Date, such increase shall be retroactive back to said Adjustment
Date with Lessee being liable for the payment in full of the aggregate of all
accrued, but unpaid amounts of rent (as the same may have been increased) on the
first day of the month following notification from Lessor of the cost of living
adjustment. Such adjustment shall be computed by multiplying the monthly rent in
effect at the commencement of Lease term, ie., ($22,500.00 per month), by a
fraction, the numerator of which is the Index figure published most nearly prior
to the respective Adjustment



                                        3
<PAGE>   31
Date and the denominator of which is the Index figure published most nearly
prior to the Commencement Date. Any of the foregoing notwithstanding, in no
event shall any such adjustment result in the rent by Lessee hereunder being
increased by less than eight and 16/100 percent (8.16%) nor greater than
thirteen and 42/100 percent (13.42%) of the rent previously in effect
immediately preceding the respective Adjustment Date. If the Index has changed
so that the days differ from that which is identified herein, the Index shall be
converted in accordance with conversion factors published by the U.S. Department
of Labor, Bureau of Labor Statistics. If the Index ceases to be published, the
parties shall agree upon another source of information to determine changes in
the purchasing power of the United States currency in the area in which the
Premises are located, and if they are unable to agree, such issue shall be
submitted to binding arbitration pursuant to the rules of the American
Arbitration Association for selection of a substitute index.

         52. PARAGRAPH 6.2 HAZARDOUS SUBSTANCES. Notwithstanding any other
provision contained in the Lease or this Addendum, Lessee shall not be liable or
responsible for any condition arising out of the presence of any Hazardous
Substance located in, on, under, or about the Premises, on or prior to the date
Lessee occupies the Premises or for any condition that occurs during the term of
the Lease arising from Hazardous Substances caused by the migration of Hazardous
Substances onto the Premises through soil, groundwater or air from adjacent
properties so long as Lessee did not cause the migration or could have
reasonably prevented the same. Lessor further agrees to indemnify, protect,
defend and hold Lessee, its agents, employees, lenders and sublessees, if any,
harmless from and against all damages, liabilities, judgments, costs, claims,
liens, expenses, penalties, permits and attorney's and consultant's fees arising
out of or involving any Hazardous Substance condition described above. Lessor's
obligation shall include, but not be limited to, the affects of any
contamination or injury to person, property or the environment and the cost of
investigation (including consultant's and attorney's fees and testing), removal,
remediation, restoration and/or abatement thereof, or any contamination therein
involved shall survive the expiration or earlier termination of this Lease. No
termination, cancellation or release agreement entered into by Lessor and Lessee
shall release Lessor from its obligation under this provision, unless
specifically so agreed by Lessee in writing at the time of such agreement."

         53. PARAGRAPH 6.3 LESSEE'S COMPLIANCE WITH LAW. Notwithstanding
anything to the contrary contained in Paragraph 6.3 or elsewhere in the Lease,
Lessee's obligation to comply with "Applicable Law" with respect to industrial
hygiene shall be limited to industrial hygiene matters relating to Lessee's
operations from the Premises.

         54. PARAGRAPH 7.1(a) LESSEE'S OBLIGATIONS. LESSOR SHALL DELIVER THE
ROOF IN WATER-TIGHT CONDITION ON THE COMMENCEMENT DATE AND LESSEE WILL BE
RESPONSIBLE FOR REPAIR AND MAINTENANCE OF THE SAME THROUGHOUT THE LEASE TERM OR
ANY EXTENSIONS THEREOF, PROVIDED, HOWEVER, LESSOR WILL BE RESPONSIBLE FOR
REPLACEMENT OF THE ROOF.

         55. PARAGRAPH 8.4 LESSEE'S PROPERTY INSURANCE. Notwithstanding anything
to the contrary contained in Paragraph 8.4 or elsewhere in the Lease, Lessee's
insurance for




                                        4
<PAGE>   32
Lessee's personal property shall be in an amount equal to full insurable value
of such property, not full replacement cost.

         56. PARAGRAPH 8.8 EXEMPTION OF LESSOR FROM LIABILITY. Notwithstanding
anything to the contrary contained in paragraph 8.8 or elsewhere in the Lease,
the limitations on Lessor's liability contained in the first two sentences of
Paragraph 8.8 shall not apply in the event of the gross negligence or willful
misconduct of Lessor.

         57. PARAGRAPH 9.4 TOTAL DESTRUCTION. Notwithstanding anything to the
contrary contained in Paragraph 9.4 or elsewhere in the Lease, in the event this
Lease shall terminate due to a Premises Total Destruction, such termination
shall occur as of the date of such Premises Total Destruction. Furthermore,
Lessor shall not have the right to recover Lessor's damages from Lessee in the
event of a Premises Total Destruction unless the damage or destruction was
intentionally caused by Lessee or due to the negligence of Lessee.

         58. PARAGRAPH 9.5 DAMAGE NEAR END OF TERM. Notwithstanding anything to
the contrary contained in Paragraph 9.5, termination of the Lease pursuant to
Paragraph 9.5 shall be effective as of the date of occurrence of such damage or
destruction.

         59. PARAGRAPH 9.6 ABATEMENT OF RENT; LESSEE'S REMEDIES. In the event
Lessor or a Lender commences the repair or restoration of the Premises within
thirty (30) days after receipt of notice from Lessee as provided in Paragraph
9.6(b) and this Lease is to continue in full force and effect as provided in
Paragraph 9.6(b), rent shall be abated in proportion to the degree to which
Lessee's use of the Premises is impaired. Any abatement of rent and other
charges under Paragraph 9.6(a) of the Lease shall commence as of the date of the
damage or destruction and continue for the period described in Paragraph 9.6(a)
of the Lease.

         60. PARAGRAPH 10.1 REAL PROPERTY TAXES. Lessee shall not be responsible
for any increases in property taxes incurred as a result of a sale or transfer
in ownership of the Property occurring on or after the date of this Lease.

to the contrary contained in Paragraph 12.1(b), only a transfer, on a cumulative
basis, of forty-nine percent (49%) or more of the voting control of Lessee shall
constitute a change in control for purposes of Paragraph 12.1. Paragraph 12.1(d)
is hereby deleted in its entirety and is replaced with the following:

                  "(d) An assignment or subletting of Lessee's interest in this

Lessee to Lessor in connection with each request for a consent to an assignment
or subletting shall be Five Hundred Dollars ($500.00).

                  (b) The occurrence of a transaction described in Paragraph

Security Deposit be increased to an amount equal to two (2) times the then
monthly base rent, not six (6) times the then monthly base rent.

                  (c) Subparagraph (h) of Paragraph 12.2 is hereby deleted in

                  (c) Lessee shall not be in Default with respect to the failure
by Lessee to make any payment of Base Rent or any other monetary payment
required to be made by Lessee under the Lease, whether to Lessor or to a third

written notice to Lessee. Payment by Lessee to Lessor shall cure any default
under the terms of this paragraph.

                  (d) Lessee shall not be in Default by reason of the failure of
Lessee to provide Lessor with reasonable evidence of insurance or any surety
bond required under this Lease unless Lessee shall fail to cure such failure

         64. PARAGRAPH 13.2 REMEDIES. Notwithstanding anything to the contrary
contained in Paragraph 13.2 or elsewhere in the Lease, Lessor shall not have the
right to exercise its remedies in the Lease, unless Lessee shall fail to perform
an affirmative duty or obligation under the Lease within the applicable cure or
grace period described in the Lease or, if no cure or grace period is stated,
unless Lessee shall fail to perform such affirmative duty or



                                        6
<PAGE>   34

contrary contained in the Lease, including without limitation, Paragraphs 13.5
and 30.1, following written notice to Lessor and the passage of five (5)
business pays without cure by Lessor, to pay such Real Property Taxes directly

so reimburse Lessee, Lessee shall have the right to deduct one hundred five
percent (105%) such costs from Lessee's next due installment(s) of rent.

         66. TENANT IMPROVEMENTS.

                           draw requests. Payment will also be contingent upon
                           inspection and approval by Lessor of the improvements
                           relating to the respective billing or draw request,
                           said approval not to be unreasonably withheld.

                           contribution towards Lessee's tenant improvements
                           shall not exceed

<PAGE>   35
                           $80,000.00 irrespective of the total cost of the

                           improvements. All tenant improvements shall be built
                           to city code and comply with all necessary
                           governmental agencies.
