     Premises, to provide for one full yearns loss of rental revenues from the
     date of any such loss. Said insurance shall contain an agreed valuation
     provision in lieu of any co-insurance clause, and the amount of coverage
     shall be adjusted annually to reflect the projected rental income, Real
     Property Taxes, insurance premium costs and other expenses, if any,
     otherwise payable, for the next 12-month period. Common Area Operating
     Expenses shall include any deductible amount in the event of such loss.

     Installations and Trade Fixtures) immediately prior to such damage or
     destruction.

            (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 fifty
     percent (50%) or more of the then Replacement Cost of the Premises
     (excluding Lessee-Owned Alterations and Utility Installations and Trade
     Fixtures) immediately prior to such damage or destruction. In addition,
     damage or destruction to the Building, other than Lessee-Owned Alterations
     and Utility Installations and Trade Fixtures of any lessees of the
     Building, the cost of which damage or destruction is fifty percent (50%) or
     more of the then Replacement Cost (excluding Lessee-Owned Alterations and
     Utility Installations and Trade Fixtures of any lessees of the Building) of
     the Building shall, at the option of Lessor, be deemed to be Premises Total
     Destruction.

            (c) "INSURED LOSS" shall mean damage or destruction to the
     Premises, other than Lessee-Owned Alterations and Utility Installations and
     Trade Fixtures, which was caused by an event required to be covered by the
     insurance described in Paragraph 8.8(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.

     9.2    PREMISES PARTIAL DAMAGE - INSURED LOSS. If 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. In the event, however, that there is a
shortage of insurance proceeds and such shortage is due to the fact that, by
reason of the unique nature of the improvements in the Premises, 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, Lessor 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 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 Lessor does not receive such funds or assurance within such
ten (10) day period, and if Lessor does not so elect to restore and repair, 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 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), 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 date 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


<PAGE>

from Lessor. Lessee shall provide Lessor with the required funds or
satisfactory assurance thereof within thirty (30) days following such
commitment from Lessee. In such event this Lease shall continue in full force
and effect, and Lessor shall proceed to make such repairs as soon as
reasonably possible after the required funds are available. If Lessee does
not give such notice and provide the funds or assurance thereof within the
times specified above, this Lease shad terminate as of the date specified in
Lessor's notice of termination.

     9.4    TOTAL DESTRUCTION. Not withstanding any other provision hereof, if
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 9.7.

     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 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 (a) exercising such option, and (b) providing Lessor with any shortage
in insurance proceeds (or adequate assurance thereof) needed to make the repairs
on or before the earlier of (i) the date which is ten (10) days after Lessee's
receipt of Lessor's written notice purporting to terminate this Lease, or (ii)
the day prior to the date upon which such option expires. If Lessee duly
exercises such option during such period and provides Lessor with funds (or
adequate assurance thereof) to cover any shortage in insurance proceeds, Lessor
shall, at Lessor's expense, repair such damage as soon as reasonably possible
and this Lease shall continue in full force and effect. If Lessee fails to
exercise such option and provide such funds or assurance during such period,
then this Lease shall terminate as of the date set forth in the first sentence
of this Paragraph 9.5.

     9.6    ABATEMENT OF RENT; LESSEE'S REMEDIES.

(a) In the event of (i) Premises Partial Damage or (ii) Hazardous Substance
Condition for which Lessee is not legally responsible, the Base Rent, Common
Area Operating Expenses and other charges, if any, payable by Lessee hereunder
for the period during which such damage or condition, its repair, remediation or
restoration continues, shall be abated in proportion to the degree to which
Lessee's use of the Premises is impaired, but not in excess of proceeds from
insurance required to be carried under Paragraph 8.3(b). Except for abatement of
Base Rent, Common Area Operating Expenses and other charges, if any, as
aforesaid, ail 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 damage, destruction, repair, remediation 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 after the receipt of such notice, this Lease shall continue in
full force and effect. "Commence" as used in this Paragraph 9 6 shall mean
either the unconditional authorization of the preparation of the required plans,
or the beginning of the actual work on the Premises, whichever occurs first.

     9.7    Refer to Adendum, Item 15.

     9.8    TERMINATION - ADVANCE PAYMENTS. Upon termination of this Lease
pursuant to this Paragraph 9, Lessor shall return to Lessee any advance payment
made by Lessee to Lessor and 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    WAIVER OF STATUTES. Lessor and Lessee agree that the terms of this
Lease shall govern the effect of any damage to or destruction of the Premises
and the Building with respect to the termination of this Lease and hereby waive
the provisions of any present or future statute to the extent it is inconsistent
herewith.

10.  REAL PROPERTY TAXES.

<PAGE>

     10.1   PAYMENT OF TAXES. Lessor shall pay the Real Property Taxes, as
defined in Paragraph 10 2(a), applicable to the Industrial Center, and except as
otherwise provided in Paragraph 10.3, any increases in such amounts over the
Base Real Property Taxes shall be included in the calculation of Common Area
Operating Expenses in accordance with the provisions of Paragraph 4.2.

     10.2   REAL PROPERTY TAX DEFINITIONS.

            (a) 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 Industrial Center 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 Industrial Center or any portion
     thereof, Lessor's right to rent or other income therefrom, andlor lessor's
     business of leasing the Premises. The term "Real Property Taxes" shad 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 Industrial Center 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.

            (b) As used herein, the term Debase Real Property Tamest shall be
     the amount of Real Property Taxes which are assessed against the Premises,
     Building or Common Areas in the calendar year during which the Lease is
     executed. In calculating Real Property Taxes for any calendar year, the
     Real Property Taxes for any real estate tax year shall be included in the
     calculation of Real Property Taxes for such calendar year based upon the
     number of days which such calendar year and tax year have in common.

     10.3   ADDITIONAL IMPROVEMENTS. Common Area Operating Expenses shall not
include Real Property Taxes specified in the tax assessor's records and work
sheets as being caused by additional improvements placed upon the Industrial
Center by other lessees or by Lessor for tile exclusive enjoyment of such other
lessees. Notwithstanding Paragraph 10.1 hereof, Lessee shall, however, pay to
Lessor at the time Common Area Operating Expenses are payable under Paragraph
4.2, the entirety of any increase in Real Property Taxes if assessed solely by
reason of Alterations, Trade Fixtures or Utility Installations placed upon the
Premises by Lessee or at Lessee's request.

     10.4   JOINT ASSESSMENT. If the Building is not separately assessed, Real
Property Taxes allocated to the Building 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 assessor's work sheets or such other information as
may be reasonably available. Lessor's reasonable determination thereof, in good
faith, shall be conclusive.

     10.5   LESSEE'S PROPERTY TAXES. Lessee shall pay prior to delinquency all
taxes assessed against and levied upon Lessee-Owned Alterations and Utility
Installations, Trade Fixtures, furnishings, equipment and all personal property
of Lessee contained in the Premises or stored within the Industrial Center. When
possible, Lessee shall cause its Lessee-Owned Alterations and Utility
Installations, 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 property shall be assessed with Lessor's real property,
Lessee shall pay Lessor the taxes attributable to Lessee's property within ten
(10) days after receipt of a written statement setting forth the taxes
applicable to Lessee's property.

11.  UTILITIES. Lessee shall pay directly for all utilities and services
supplied to the Premises, including, but not limited to, electricity, telephone,
security, gas and cleaning of the Premises, together with any taxes thereon. If
any such utilities or services are not separately metered to the Premises or
separately billed to the Premises, Lessee shad pay to Lessor a reasonable
proportion to be determined by Lessor of all such charges jointly metered or
billed with other premises in the Building, in the manner and within the time
periods set forth in Paragraph 4.2(d).

12.  ASSIGNMENT AND SUBLETTING.

     12.1   LESSOR'S CONSENT REQUIRED.

            (a) Lessee shall not voluntarily or by operation of law assign,
     transfer, mortgage or otherwise transfer or encumber (collectively,
     "assign") 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.

<PAGE>

            (b) A change in the control of Lessee shall constitute an
     assignment requiring Lessors 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.

            (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, or a non-curable
     Breach without the necessity of any notice and grace period. If Lessor
     elects to treat such unconsented to assignment or subletting as a
     non-curable 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 for the Premises to the greater
     of the then fair market rental value of the Premises, as reasonably
     determined by Lessor, or one hundred ten percent (110%) of the Base Rent
     then in effect. 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 rental
     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 as reasonably determined by Lessor (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, (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 rental bears to the Base Rent in effect immediately prior the
     adjustment specified in Lessor's Notice.

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

     12.2   TERMS AND CONDITIONS APPLICABLE TO ASSIGNMENT AND SUBLETTING.

            (a) Regardless of Lessor's consent, any assignment or subletting
     shall not (i) be effective without the express written assumption by such
     assignee or sublessee of the obligations of Lessee under this Lease, (ii)
     release Lessee of any obligations hereunder, nor (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 for
     performance shall constitute a waiver or estoppel of Lessor's right 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 assignee
     or sublessee.

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

            (e) Each request for consent to an assignment or subletting shall
     be in writing, accompanied by information relevant to Lessor's
     determination as to the financial and operational responsibility and
     appropriateness of the proposed assignee or sublessee, including, but not
     limited to, the intended use and/or required modification of the Premises,
     if any, together with a non-refundable deposit of $1,000 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

<PAGE>

     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.

     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 the foregoing provision 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 such 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 said option to the
     expiration of such sublease; provided, however, Lessor shall not be liable
     for any prepaid rents or security deposit paid by sud 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 under a sublease approved by Lessor shall further
     assign or sublet all or any part of the Premises without Lessor's prior
     written consent.

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

13.  DEFAULT; BREACH; REMEDIES.

     13.1   DEFAULT; BREACH. 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" by Lessee is
defined as a failure by Lessee to observe, comply with or perform any of the
terms, covenants, conditions or rules applicable to Lessee under this Lease. A
"Breach" by Lessee 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 vacating of the Premises without the intention to reoccupy
     same, or 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, Lessee's Share of
     Common Area Operating Expenses, or any other monetary payment required to
     be made by Lessee hereunder 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

<PAGE>

     continues for a period of flve (5) 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

     Applicable Requirements per Paragraph 6 3, (ii) the inspection, maintenance
     and service contracts required under Paragraph 7.1(b), (iii) the rescission
     of an unauthorized assignment or subletting per Paragraph 12.1, (iv) a

     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 13.1(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.

            (e) The occurrence of any of the following events: (i) the making
     by Lessee of any general arrangement or assignment for tile benefit of
     creditors; (ii) Lessee's becoming a "debtor" as defined in 11 U.S. Code

     days); (iii) the appointment of a trustee or receiver to take possession of

     seizure of substantially all of Lessee's assets located at the Premises or
     of lessee's interest in this Lease, where such seizure is not discharged
     within thirty (30) days; provided, however, in the event that any provision
     of this Subparagraph 13.1 (e) is contrary to any applicable law, such
     provision shall be of no force or effect, and shall not affect the validity
     of the remaining provisions.

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

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

13.2 REMEDIES. If Lessee fails to perform any 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 therefore If any check given to Lessor by Lessee
shall not be honored by the bank upon which it is drawn, Lessor, at its own
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

<PAGE>

     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
     any leasing commission paid by Lessor in connection with this Lease
     applicable to the unexpired term of this Lease. The worth at the time of
     award of the amount referred to in provision (iii) of the immediately
     preceding sentence shall be computed by discounting such amount at the
     discount rate of the Federal Reserve Bank of San Francisco or the Federal
     Reserve Bank District in which the Premises are located at the time of
     award plus one percent (1%). 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 13.2. If termination of this Lease
     is obtained through the provisional remedy of unlawful detained Lessor
     shall have the right to recover in such proceeding the unpaid rent and
     damages as are recoverable therein, or Lessor may reserve the right to
     recover all or any part thereof in a separate suit for such rent and/or
     damages. If a notice and grace period required under Subparagraph 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
     Subparagraph 13.1 (b), (c) or (d). In such case, the applicable grace
     period 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 (2) such grace periods shall constitute both
     an unlawful detainer and a Breach of this Lease entitling Lessor to the
     remedies provided for in this Lease and/or by said statute.

            (b) Continue the Lease and Lessee's right to possession in effect
     (in California under California Civil Code Section 1951.4) after Lessee's
     Breach and recover the rent as it becomes due, provided Lessee has the
     right to sublet or assign, subject only to reasonable limitations. Lessor
     and Lessee agree that the limitations on assignment and subletting in this
     Lease 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 this 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.

     13.4   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 deed of trust covering the
Premises. Accordingly, if any installment of rent or 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 late charge by Lessor shall in no event constitute
a waiver of Lessee's Default or Breach with respect to such overdue amount, nor
prevent 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

<PAGE>

reasonable time slnall in no event be less than thirty (30) days after
receipt by Lessor, and by any Lender(s) whose name and address shall have
been furnished to 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-tive percent (25%) of the portion of
the Common Areas designated for Lessee's parking, 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 Premises. No reduction of Base
Rent shall occur if the condemnation does not apply to any portion of the
Premises. 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 of 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 Lessee's share of the legal and
other expenses incurred by Lessor in the condemnation matter, repair any damage
to the Premises caused by such condemnation authority. Lessee shall be
responsible for the payment of any amount in excess of such net severance
damages required to complete such repair.

the American Industrial Real Estate Association, plus such additional

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 LIABILITY. The term "Lessor" as used herein shall mean the owner
or owners at the time in question of the fee title to the Premises. 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 15.3, 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 ten (10) days
following the date on which it was due, shall bear interest from the date

<PAGE>

due at the prime rate charged by the largest state chartered bank in the
state in which the Premises are located plus four percent (4%) per annum, but
not exceeding the maximum rate allowed by law, in addition to the potential
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. Each Broker shall be an intended third party beneficiary
of the provisions of this Paragraph 22.

23.  NOTICES.

     23.1   NOTICE REQUIREMENTS. All notices required or permitted by this
Lease shall be in writing and may be delivered in person (by hand or by
messenger or courier service) or may be sent by regular, certified or registered
mail or U.S. Postal Service Express Mail, with postage prepaid, 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   DATE OF NOTICE. Any notice sent by registered or certified mail,
return receipt requested, shall be deemed given on the date of delivery shown on
the receipt card, or if no delivery date is shown, the postmark thereon. If sent
by regular mail, the notice shall be deemed given three (3) business days 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 Postal Service or courier. If any
notice is transmitted by facsimile transmission or similar means, the same shall
be deemed served or delivered upon telephone or facsimile confirmation of
receipt of the transmission thereof, provided a copy is also delivered via
delivery or mail. If notice is received on a Saturday or a Sunday or a 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 any other term, covenant or condition hereof. Lessor's consent
to, or approval of, any such 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 shad not be a waiver of any Default or Breach by Lessee of any
provision hereof. Any payment given Lessor by Lessee may be accepted by Lessor
on account of monies or damages due Lessor, notwithstanding any qualifying
statements or conditions made by Lessee in connection therewith, which such
statements and/or conditions shall be of no force or effect whatsoever unless
specifically agreed to in writing by Lessor at or before the time of deposit of
such payment.

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.
In the event that Lessee holds over in violation of this Paragraph 26 then the
Base Rent payable from and after the time of the expiration or earlier
termination of this Lease shall be increased to one hundred twenty five percent
(125%) of the Base Rent applicable during the month immediately preceding such
expiration or earlier termination. Nothing contained herein shall be construed
as a consent by Lessor to any holding over by Lessee.

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

<PAGE>

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 pursuant
to Paragraph 13 5. 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 (1 ) month's rent.

     30.3   NON-DISTURBANCE. With respect to Security Devices entered into by
Lessor after the execution of this Lease, Lessee's subordination of this Lease
shall be subject to receiving 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 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.  ATTORNEYS' 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) in any such proceeding, action, or appeal thereon, shall be
entitled to reasonable attorneys' fees. Such fees may be awarded in the,same
suit or recovered in a separate suit, whether or not such action or proceeding
is pursued to decision or judgment. The term "PREVAILING PARTY" shall include,
without limitation, a Party or Broker who substantially obtains or defeats the
relief sought, as the case may be, whether by compromise, settlement, judgment,
or the abandonment by the other Party or Broker of its claim or defense. The
attorneys fee award shall not be computed in accordance with any court fee
schedule, but shall be such as to fully reimburse all attorneys' fees reasonably
incurred. Lessor shall be entitled to attorneys fees, costs and expenses
incurred in 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. Broker(s) shall be intended
third party beneficiaries of this Paragraph 31.

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, 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 at any time
during the last one hundred eighty (180) days of the term hereof place on or
about the Premises any ordinary "For Leased signs. All such activities of Lessor
shall be without abatement of rent or liability to Lessee.

<PAGE>

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 exterior of the Premises or
the Building, 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 so long as such signs are in a location designated by
Lessor and comply with Applicable Requirements and the signage criteria
established for the Industrial Center by Lessor. 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).
Unless otherwise expressly agreed herein, Lessor reserves all rights to the use
of the roof of the Building, and the right to install advertising signs on the
Building, including the roof, which do not unreasonably interfere with the
conduct of Lessee's business; Lessor shall be entitled to all revenues from such
advertising signs.

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 and
     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, shall be paid
     by Lessee to Lessor upon receipt of an invoice and supporting documentation
     therefor. In addition to the deposit described in Paragraph 12.2(e), 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. 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
     acknowledgement 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
     impositions by Lessor at ttle 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   FORM OF GUARANTY. 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 such 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 required in
Paragraph 16.

     37.2   ADDITIONAL OBLIGATIONS OF GUARANTOR. 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 Lease, including the authority of the Guarantor (and
of the party signing on Guarantor's behalf) to obligate such Guarantor on said
guaranty, and 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.

<PAGE>

38.  QUIET POSSESSION. Upon payment by Lessee of the rent for the Premises and
the 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.

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

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.

     notwithstanding any provision in the grant of Option to the contrary: (i)
