 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
 Alteration 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, 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 in Paragraph 9.11(c).

        (b) Rental Value. The Insuring Party shall, in addition, obtain and keep

rental increases). Said insurance shall provide that in the event the Lease is
terminated by reason of an insured loss, the period of indemnity for such
coverage shall be extended beyond the date of the completion of repairs or
replacement of the Premises, to provide for one full year's loss of 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.

        (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 if Lessee is the Insuring Party, the policy carried by Lessee

Insurance policies referred to in this Paragraph 8.  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.

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
cooperated with Lessee in such defense.  Lessor need not have first paid any
such claim in order to be so indemnified.

installment due, at least twenty (20) days prior to the applicable delinquency
date, or (ii) monthly in advance with the payment of the Base Rent. If Lessor
elects to require payment monthly in advance, the monthly payment shall be that
equal monthly amount which, over the number of months remaining before the month
in which the applicable tax installment would become delinquent (and without
interest thereon), would provide a fund large enough to fully discharge before
delinquency the estimated installment of taxes to be paid.  When the actual
amount of the applicable tax bill is known, the amount of such equal monthly
advance payment shall be adjusted as required to provide the fund needed to pay
the applicable taxes before delinquency.  If the amounts paid to Lessor by
Lessee under the provisions of this Paragraph are insufficient to discharge the
obligations of Lessee to pay such Real Property Taxes as the same become due,
Lessee shall pay to Lessor, upon Lessor's demand, such additional sums as are
necessary to pay such obligations.  All moneys paid to Lessor under this
Paragraph may be intermingled with other moneys of Lessor and shall not bear
interest.  In the event of a Breach by Lessee in the performance of the
obligations of Lessee under this Lease, then any balance of funds paid to Lessor
under the provisions of this Paragraph may, subject to proration as provided in

action shall not relieve such persons from liability under this Lease or
sublease.

        (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 t, 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
acception 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 ten 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.

        (h) Lessor, as a condition to giving its consent to any assignment or
subletting, may require that the amount and adjustment structure of the rent
payable under this Lease be adjusted to what is then the market value and/or
adjustment structure for property similar to the Premises as then constituted.

    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 tot he 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 fright 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 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 or 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, 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), $1,000.00 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"


                                                        Initials _______
NET                             PAGE 6

is defined as the occurrence of any one or more of the following Defaults, and,
where a grace period to cure after notice is specified herein, the failure by
Lessee to cure such Default prior to the expiration of the applicable grace
period, 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 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, if 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. (a) 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. $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 a 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 effect 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.

        (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 assurance or security, which when coupled with the then existing
resources of Lessee, equals or exceeds the combined financial resources of
Lessee and the guarantors that existed at the time of execution of this Lease.

   13.2 Remedies. If Lessee fails to perform any 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; (ii) 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 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.  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 Lesso
eserve therein the right to recover all or any part thereof in a separate suite
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.

        (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 Less 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 such
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 therefore 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, notwithstanding
any subsequent cure of said Breach by Lessee.  the acceptance by Lessor of rent
or the cure of the Breach which initiated the operation of this Paragraph shall
not be deemed a waiver by Lessor of the provisions of this Paragraph unless
specifically so stated in writing by Lessor at the time of such acceptance.

   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 five (5) 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 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


                                                        Initials _______
NET                             PAGE 7



all  or a portion of the Premises are taken by condemnation and Lessee is
therefore unable to continue to operate Lessee's business from the Premises
title or possession, whichever first occurs.  - 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 Leases in accordance with the
forgoing, 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.  Lessee waives any and all rights it might otherwise
have under Section 1265.130 of the California Code of Civil Procedure to
terminate this Lease as a result of any taking.

15.	Broker's Fee.

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

        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.

        15.6  Lessor and Lessee hereby consent to 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) day after
written notice from the other Party (the "Requesting Party") execute,
acknowledge and deliver to the Requesting Party a statement in writing in form
attached hereto as Exhibit "D" plus such additional information, confirmation
and/or statements as may be reasonably requested by the Requesting Party.

        16.2  If 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 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, 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 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.

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, 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

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 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 required such consent.  Regardless of
Lessor's knowledge of 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 qualify 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.  Neither Lessor nor Lessee shall record this Lease or a short
form memorandum of this Lease.

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

27.  Cumulative Remedies.  No remedy or election hereunder shall be deemed
exclusive but shall, wherever feasible, 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 (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 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 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 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 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 of its claim or defense.  The attorney's fees
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 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.  See addendum.

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 the
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 .11,
the form of the guaranty to be executed by each such Guarantor shall be in the
form provided by Lessor 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 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
boar do directors authorizing the making of such guaranty, together with a
certificate of incumbency showing the signature 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 of 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

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 or
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
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 have given to Lessee
three (3) or more notices of Default under Paragraph 13.1 during any twelve (12)
month period, 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'' 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 (3) or more notices of Default under Paragraph 13.1 during any
twelve (12) month period, whether or not the Defaults are cured, or (iii) if
Lessee commits a Breach of this Lease.

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 tenant 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
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,
dedications, maps and restrictions do not unreasonably interfere with the use of
the Premises by Lessee and do not materially impede Lessee's access to and from
the Premises and do not reduce Lessee's parking capacity to less than four (4)
spaces per 1000 square feet of the Premises.  Lessee agrees to sign within five
(5) days of request, 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 of
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 of 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 entities named herein as such Lessor or Lessee.

            TR BRELL, CAL CORP, AN ILLINOIS CORPORATION ("LESSOR"),

      SOURCE SCIENTIFIC SYSTEMS, INC., A DELAWARE  CORPORATION ("LESSEE")
      -------------------------------------------------------------------


        The promises, convenants agreements and declarations made and set forth
herein are intended to and shall have the same force and effect as if set forth
at length in the body of the Lease to which this Addendum is attached (the
"Lease").  To the extent that the provisions of this Addendum are inconsistent
with the terms and conditions of the Lease, the terms of this Addendum shall
control.

        48(a).  Paragraph 1.7 (Security Deposit). Lessor acknowledges that
Lessor presently holds the Security Deposit referenced in Paragraph 1.7 under
Lessee's existing lease which wil continue to be held by Lessor pursuant to the
terms of this Lease.

        49.     Paragraph 4.1(Base Rent).  The Base Rent shall be increased
effective as of August 1, 1997 to $29,131 per month and increased again
effective as of February 1, 2000 to $32,460.00.  Lessor hereby grants Lessee six
(6) months of one-half (1/2) rent for the months of February through July of
1995.

        50.     Paragraph 6.1(Use).  The following is hereby added to paragraph
6.1.

        "Lessee shall not do anything or suffer anything to be done in or about
        the Premises which will in any way conflict with any law, statute,
        ordinance or other governmental rule, regulation or requirement now in
        force or which may hereafter be enacted or promulgated.  Should any
        standard or regulation now or hereafter be imposed on Lessor or Lessee
        by a State, federal or local governmental body charged with the
        establishment, regulation and enforcement of occupational, health or
        safety standards for employers, employees, lessors or lessees, then,
        except as otherwise specifically set forth in the Lease, Lessee agrees,
        at its sole cost and expense, to comply promptly with such standards or
        regulations."


        51.     Paragraph 6.3(Lessee's Compliance with Law).  The following
language is hereby added to Paragraph 6.3:
	
        "In addition to the general obligation of Lessee to comply with laws and
        without limitation thereof, Lessee shall comply in all respects with the
        Title III of the Americans with Disabilities Act of 1990 (the "ADA") as
        respects Lessee's use of, or alteration to, the Premises and Lessor
        shall not be liable to Lessee, nor shall this Lease be affected in any
        way, by reason of any moratorium, initiative, referendum, statute,
        regulation or other governmental decree or action which could in any
        manner prevent or limit the parking rights of Lessee hereunder.  Any
        governmental charges or surcharges or other monetary obligations imposed
        relative to parking rights with respect to the Premises shall be
        considered assessments and shall be responsible for compliance with the
        ADA if it is required with respect to the exterior of the Premises or
        the structure of the Building, and such compliance does not relate to
        Lessee's specific use of the Premises."

        52.     Paragraph 7.1(Lessee's Obligations);Paragraph 7.2(Lessor's
Obligations). In connection with Paragraph 7.1 of the Lease, all repairs and
maintenance of the Premises by Lessee as required under the Lease shall be
performed in a first class manner by contractors and other personnel reasonably
approved by Lessor, shall be performed in accordance with a repair and
maintenance plan reasonably approved by Lessor, and shall comply with guidelines
and shall meet such standards of quality as may be reasonably established by
Lessor from time to time during the Term of the Lease, including, without
limitation, providing Lessor with copies of all permits obtained by Lessee and
"as-built" drawings of such work performed by Lessee.  In the


9504800R.OC1/DWW/K4933-002/05-17-95/meg



event Lessor determines, at any time during the term of the Lease, that Lessee's
repair and maintenance of the Premises is not meeting the standards therefor
established by Lessor, then Lessor may, but shall not be obligated to, undertake
such repair and maintenance obligations of Lessee on behalf of Lessee, and all
costs and expenses incurred by Lessor in the performance of such repair and
maintenance shall constitute additional rent under this Lease, and shall be
payable by Lessee to Lessor within five (5) days of demand.

        Notwithstanding anything to the contrary contained in Paragraphs 7.1 or
7.2, in addition to Monthly Base Rent, throughout the Term of this Lease, Lessee
agrees to pay Lessor as additional rent in accordance with the terms of this
Paragraph certain operating expenses of the Building ("Operating Expenses")
consisting of all Real Property Taxes pursuant to Paragraph 10 of the Lease, the
cost of all insurance premiums for property and liability insurance maintained
by Lessor pursuant to Paragraph 8 of the Lease, and costs and expenses incurred
by Lessor with respect to landscaping, repair and maintenance of the Building
exterior, and other exterior portions of the Premises, parking areas, including
resurfacing, repairing and restriping, walkways, sanitary sewer costs, and trash
disposal, including costs and maintenance of refuse receptacles,  costs of
repair and replacement of directional signs and markers, car stops, exterior
lighting and other utilities, reasonable depreciation on improvements,
machinery, and equipment used in connection with such maintenance and any other
costs and expenses incurred by Lessor with respect to the maintenance and repair
of the Building and exterior portions of the Premises.

                (a)     Estimate Statement.  On or about March 1st of each
        calendar year during the Term of this Lease, Lessor will endeavor to
        deliver to Lessee a statement ("Estimate Statement") wherein Lessor will
        estimate the Operating Expenses of the then current calendar year.
        Lessee agrees to pay Lessor, as "Additional Rent", one-twelfth (1/12th)
        of such Operating Expenses each month thereafter, beginning with the
        next installment of rent due, until such time as Lessor issues a revised
        Estimate Statement or the Estimate Statement for the succeeding calendar
        year, except that, concurrently with the regular monthly rent payments
        next due following the receipt of each such Estimate Statement, Lessee
        agrees to pay Lessor an amount equal to one monthly installment of such
        Operating Expenses (less any applicable Operating Expenses already paid)
        multiplied by the number of months from January, in the current calendar
        year, to the month of such rent payment next due, all months inclusive.
        If at any time during the Term of the Lease, but not more often than
        quarterly, Lessor reasonably determines that Operating Expenses for the
        current calendar year will be greater than the amount set forth in the
        then current Estimate Statement, Lessor may issue a revised Estimate
        Statement and Lessee agrees to pay Lessor, within ten (10) days of
        receipt of the revised Estimate Statement, the difference between the
        amount owed by Lessee under such revised Estimate Statement and the
        amount owed by Lessee under the original Estimate Statement for the
        portion of the then current calendar year which has expired.  Thereafter
        Lessee agrees to pay Operating Expenses based on such revised Estimate
        Statement until Lessee receives the next calendar year's Estimate
        Statement or a new revised Estimate Statement for the current calendar
        year.
		
                (b)     Actual Statement.  By March 1st of each calendar year
        during the Term of this Lease, Lessor will also endeavor to deliver to
        Lessee a statement ("Actual Statement") which states the actual
        Operating Expenses for the preceding calendar year.  If the Actual
        Statement reveals that actual Operating Expenses are more than the total
        Additional Rent paid by Lessee for Operating Expenses on account of the
        preceding calendar year, Lessee agrees to pay Lessor the difference in a
        lump sum within ten (10) days of receipt of the Actual Statement.  If
        the Actual Statement reveals that actual Operating Expenses are less
        than the Additional Rent paid by Lessee for Operating Expenses on
        account of the preceding calendar year, Lessor will credit any
        overpayment toward the next monthly installment(s) of Operating Expenses
        due under this Lease.

                Notwithstanding anything to the contrary contained in Paragraphs
7.1 or 7.2, Lessee agrees to maintain and repair the roof of the Building, at
Lessee's sole cost and expense.  If the roof needs to be replaced (as determined
below), Lessor shall cause such work to be performed, but Lessee shall be
responsible for reimbursing Lessor for a portion of the cost ("Replacement
Cost") incurred by Lessor for replacing the roof with a roof of a quality
consistent with the structure and quality of the Building and which is full
warranted for a minimum of 15

years, based on the following schedule: (i) if the roof is replaced during
months 1 through 28 of the new Term, then Lessee shall be responsible for 25% of
the Replacement Cost, or (ii) if the roof is replaced during 29 through 56 of
the new Term, then Lessee shall be responsible for 45% of the Replacement Cost,
or (iii) if the roof is replaced during months 57 through 84 of the new Term,
then Lessee shall be responsible for 65% of the Replacement Cost.  The roof will
"need" to be replaced if two independent roofing consultants, one selected by
Lessor and the other selected by Lessee, advise Lessor that replacement of the
roof is recommended over further repair in order for the roof to function
properly.  If a third roofing consultant is necessary because of disagreement in
the need for roof replacement between the first two consultants, then Lessor and
Lessee shall cause their respective consultants to agree upon and mutually
select a third roofing consultant whose determination shall be conclusive.  If
the roof needs to be replaced because of damage caused by Lessee or its agents,
employees, contractors or invitees, then Lessee will be responsible for the
entire Replacement Cost.  Lessee shall pay its share of the Replacement Cost
concurrently with Lessor's payment of the balance of the Replacement Cost in
accordance with the terms of Lessor's contract with the roof installation
company.

                53.     Paragraph 7.3(Utility Installations; Trade Fixtures;
Alterations).  The following is added to Paragraph 7.3 of the Lease.

                "(d)    Security.  In connection with Paragraph 7.3 of the
        Lease, Lessee shall, at Lessee's sole cost and expense, take such
        security measures as Lessee deems appropriate or necessary in order to
        secure the Premises and portions thereof in accordance with such
        requirements as may be imposed by contractors of Lessee; provided,
        however, in the event any such security measures require any alterations
        of or additions to the Premises, any such alterations and/or additions
        shall be subject to the terms of Paragraphs 7.3 and 7.4 of the Lease."

                54. Paragraph 8.2(Liability Insurance). Paragraph 8.2(a) of the
Lease has been intentionally omitted, and is hereby replaced with the following:

                "(a)    Carried by Lessee.  Lessee agrees, at its own expense,
        to maintain in full force and effect at all times during the term of
        this Lease, as it may be extended for the protection of Lessee and
        Lessor, as their interests may appear, policies of insurance issued by a
        carrier or carriers acceptable to Lessor and with a rating consistent
        with the requirements of Paragraph 8.5 of the Lease, which afford the
        following coverages:  (i) Worker's compensation: statutory limits; (ii)
        Employer's liability: not less than Five Hundred Thousand Dollars
        ($500,000.00); (iii) Comprehensive general liability insurance including

        injury (including employees), owned/non-owned auto liability, pollution
        and hazardous materials liability, completed operations, products
        liability, and fire damage: not less than Three Million Dollars
        ($3,000,000.00) with a combined single limit for both bodily injury and
        property damage and naming Lessor, Lessor's agents and Lessor's
        mortgagees as additional insureds as their respective interests may
        appear; (iv) except to the extent covered by the insurance for the
        Premises and leasehold improvements required to be carried by the
        Insuring Party under Paragraph 8.3(a) of the Lease, "All Risk" property
        insurance (including, without limitation, vandalism, malicious mischief,
        water damage, earthquake, damage from pollution and hazardous materials,
        course of construction endorsement, sprinkler leakage endorsement,
        debris removal and demolition coverage, and boiler and machinery
        coverage) on the Premises and the leasehold improvements, Utility
        Installations, Alterations, Trade Fixtures, and Lessee's personal
        property located on or in the Premises, which shall be in a form
        providing coverage comparable to the coverage provided in the standard
        ISO All-Risk form and in an amount equal to the full amount of the
        replacement cost of the insured items, as the same may from time to time
        increase as a result of inflation or and (v) boiler and machinery
        insurance, including, but not limited to, steam pipes, pressure pipes,
        condensation return pipes and other pressure vessels and HVAC equipment,
        with limits per accident of not less than the replacement cost of all
        leasehold improvements, Utility Installments (except to the extent
        covered by the insurance for the Premises and leasehold improvements
        required to be carried by the Insuring Party under

        Paragraph 8.3(a) of the Lease), Alterations, Trade Fixtures, and
        Lessee's personal property and all boilers, pressure valves, HVAC
        equipment and miscellaneous  electrical and mechanical equipment in the
        Premises, all with deductibles not to exceed $1,000.00 per occurrence.
        The insurance policies set forth above shall not contain any
        intra-insured exclusions as between insured persons or organizations,
        but shall include coverage for liability assumed under Lease as in
        "insured contract" for the performance of Lessee's indemnity obligations
        under the Lease.  The limits of said insurance required by the 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."

                55. Paragraph 9 (Damage or Destruction). The following
definitions shall apply for purposes of Paragraph 9.1(a) and 9.1(b).

                        (a) "Premises Partial Damage" shall mean damage or
destruction to the Premises, other than Lessee Owned Alterations and Utility
Installations, the repair time for which, as reasonably determined by Lessor,
will not exceed one hundred eighty (180) days

                        (b) "Premises Total Destruction" shall mean damage or
destruction to the Premises, other than Lessee Owned Alterations and Utility
Installations, the repair time for which, as reasonably determined by Lessor,
will not exceed one hundred eighty (180) days.

                Notwithstanding anything to the contrary set forth in Paragraph
9 of the Lease, Lessee hereby waives the provisions of California Civil Code
Sections 1932 and 1933, and any successor sections and any other statues which
are inconsistent with the provisions of Lease and which relate to the
termination of leases when leased property is destroyed, and agree that such
event shall be governed by the terms of the Lease.

                56. Paragraph 13.2 (Remedies). The following language is hereby
added to Paragraph 13.2:

                "(e)    Re-enter the Premises at its option without declaring
        the Lease term ended, and re-let the whole or any part thereof for the
        account of Lessee, on such terms and conditions and at such rent as
        Lessor may deem proper, collecting such rent and applying it on the
        amount due from Lessee hereunder and on the expense of such relating and
        on any other damage or expense so sustained by Lessor, or on any such
        item or items, recovering from Lessee the difference between the
        proceeds of such re-letting and the amount of the rentals reserved
        hereunder, and any such damage or expense from time to time, which said
        sum Lessee agrees to pay upon demand.  Lessor shall not, by any re-entry
        or other act, be deemed to have terminated this Lease or the liability
        of Lessee for the total rental hereunder(net of re-let recovery as
        specified above), or any installment thereof then due or thereafter
        accruing, or for damages, unless Lessor shall notify Lessee, in writing,
        that Lessor has so elected to terminate the Lease."

                57.     Paragraph 17 (Lessor's Liability).  The following is
added to Paragraph 17:

                "Lessee acknowledges and agrees that the obligations of Lessor
        under this Lease do not constitute personal obligations of the
        individual partners, directors, officers or shareholders of Lessor, and
        Lessee shall look to the real estate that is the subject of this Lease
        and to any insurance proceeds received from insurance policies required
        to be carried under this Lease, and to no other assets of Lessor for the
        satisfaction of any liability with respect to this Lease, and will not
        seek recourse against the individual partners, directors, officers or
        shareholders of Lessor or any of their personal assets for such
        satisfaction."

58.     Paragraph 24 (Waivers).  The following language is hereby added to
Paragraph 24: 

                                      -4-

9504800R.OC1/DWW/K4933-002/05-17-95/meg



                "No payment by Lessee or receipt by Lessor of a lesser amount  
        than the fixed rent payment herein stipulated shall be deemed to be 
        other than on account of the earliest  stipulated rent, nor shall any 
        endorsement or statement on any check or any letter accompanying any
        check or any payment as rent be deemed an accord and satisfaction, and 
        Lessor may accept such check or payment without prejudice to Lessor's 
        right to recover the balance of such rent or pursue any other remedy in
        this Lease provided."

                59. Paragraph 26 (Holding Over).  The following language is
hereby added to Paragraph 26:

                "If  Lessee remains in possession of all or any part of the
        Premises after the expiration of the Term of the Lease without Lessor's
        written consent (which may be withheld at Lessor's sole and absolute
        discretion),  Lessee shall become a Lessee at sufferance only and such
        tendency shall not constitute a renewal or extension for any further
        term.  In such event, Base Rent shall be increased to an amount equal to
        one hundred fifty percent(150%) of the Base Rent payable during the last
        month of the Term, and any other sums due hereunder shall be payable in
        the amount of the terms specified in this Lease.  Such tenancy shall be
        subject to every other term, condition, and covenant contained herein.
        The foregoing provisions of this Paragraph 26 are in addition to and do
        not affect any rights of  Lessor under the Lease or as otherwise
        provided by law.  If Lessee fails to surrender the Premises upon the
        expiration of this Lease despite the demand to do so by Lessor, Lessee
        shall indemnify and hold Lessor harmless from all loss or liability
        including, without limitation, any claim made by any succeeding lessee
        founded on or resulting from such failure to surrender."

                60. Paragraph 30  (Subordination; Attornment ;
Non-Disbursement.)  With respect to Paragraph 30 of the Lease, neither Lessor
nor Lessee shall unreasonably withold its consent to changes or amendments to
the Lease requested by any Lender of Lessor having a security interest in the
Premises or the Lease, so long as the changes do not alter the basic business
terms of the Lease or otherwise materially diminish any rights or materially
increase any obligation of the party from who consent to such change or
amendment is requested. Notwithstanding any contrary provision of Paragraph 30.1
of the Lease, Lessee agrees to send by certified mail to any Lender whose
address has been furnished to Lessee, a copy of any notice of default served by
Lessee on Lessor, and if Lessor fails to cure such default within the time
provided for in the Lease, such Lenders shall have an additional thirty (30)
days to cure such default; provided however, that if such default cannot
reasonably be cured within such thirty (30) day period, then such Lenders shall
have such additional time to cure the default as is reasonably necessary under
the circumstances, provided such Lenders commence the cure of such default
within said thirty (30) day period and diligently pursue the same to completion.

                60(a.)  Paragraph 34 (Signs).  Lessee will have no right to
install or maintain any Lessee identification signs (or any other signs, banners
or other such displays) upon the Premises which may be visible from the exterior
of the Premises, except as (I) have been expressly approved by Lessor prior to
the installation thereof, and (ii) are consistent and compatible with (A) the
restrictions contained in this Paragraph 60(a), (B) all governmental regulations
and requirements, ( C ) rules and regulations from time to time promulgated by
Lessor with respect to the Building, a current copy of which is attached hereto
as Exhibit "B", and (D) all private covenants and restrictions now or hereafter
of record affecting the Premises.  All approved signs (the "Building Sign") if
any must be maintained, at the sole cost and expense of Lessee, pursuant to a
maintenance program approved and supervised by Lessor.  Upon expiration of
earlier termination of the Lease, Lessee, at Lessee's sole cost and expense
(subject to Lessor's supervision), will cause the Builiding Sign to be removed
and the Building to be restored to condition existing prior to the placement of
such sign.  If Lessee fails to remove such sign and restore the Building as
provided above within thirty (30) days following Lessor's demand therefor, then
Lessor may perform such work and all costs and expenses incurred by Lessor in so
performing such work will be reimbursed by Lessee to L4essor within ten (10)
days following Lessor's delivery to Lessee of an invoice therefor.  The sign
rights herein above provided are personal to the original Lessee executing this
Lease and may not be assigned or transferred to, or utilized by, any other
person or entity.

                61. Net Lease.      This Lease shall be deemed and construed to
be a "net lease" and except as herein otherwise expressly set forth Lessee shall
pay to Lessor, absolutely net throughout the Term of this Lease, the Base Rent
(as adjusted persuant to Subparagraph 48(b) above), additional rent and other
payments hereunder, without abatement or set off.

                62.     Option to Extend Term:  Lessor hereby grants to Lessee
one (1) option ("Option to Extend") to extend the Term of this Lease for a
period of five (5) years ('Option Term'').  The Option must be exercised if at
all by written notice ("Option to Extend Notice") delivered by Lessee to Lessor
not earlier than one hundred eighty (180) days nor later than ninety (90) days
prior to the end of the initial five (5) year Term.  Further, the Option to
Extend shall not be deemed to be properl7y exercised if, as of the date of the
Option Notice and at the end of the initial (5) year Term, Lessee is in default
under the Lease. In the event the initial five (5) year Term shall be extended
as provided in this Paragraph 62, then all of the terms, covenants and
conditions of the Lease shall remain unmodified and in full force and effect,
except for payment of Monthly Basic Rent.  Monthly Basic Rent shall be adjusted
as of the commencement date of the Option Term in accordance with the "fair
market rental rate" for the Premises determined as follows.

                        (a)     The term "fair market rental rate" as used
        herein will mean the annual amount per rentable square foot, projected
        during the relevant period, that a willing, comparable, non-equity
        tenant (excluding sublease and assignment transactions) would pay, and a
        willing comparable landlord of a comparable industrial building located
        in the vicinity of the Building would accept, at arm's length (what
        Lessor is accepting in current transactions for the Building may be
        considered), for space of comparable size, quality and floor height as
        the leased area at issue taking into account the age, quality and layout
        of the existing improvements in the lease area at issue and taking into
        account items that professional real estate brokers customarily
        consider, including, but not limited to rental rates, space
        availability, tenant size, tenant  improvement allowances, operating
        expenses, reduced rent, free rent and any other lease concessions, if
        any, then being charged or granted by Lessor or the lessors of such
        similar buildings.  The fair market rental rate will be an effective
        rate, not specifically including, but accounting for appropriate
        economic concessions described above.

                        (b)     If a determination of fair market rental rate is
        required under this Lease, then Lessor will provide written notice of
        Lessor's determination of the fair market rental rate not later than
        thirty (30) days after the date upon which Lessee timely exercises the
        right giving rise to necessity for such fair market rental rate
        determination. Lessee will have thirty (30) 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 reasonably
        object thereto in writing.  Lessee's failure to object to the fair
        market rental rate submitted by Lessor in writing within Lessee's Review
        Period, Lessor and Lessee will 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 an agreement on such fair market rental rate
        within fifteen (15) days following the expiration of Lessee's Review
        Period (the "Outside Agreement Date"), then each party's determination
        will be submitted to appraisal in accordance with the provisions below.

                (c)      (i)     Lessor and Lessee will each appoint one (1)
           independent appraiser who by profession must be a real estate broker
           who has been active over the five (5) year period ending on the date
           of such appointment in the leasing of industrial properties located
           in the vicinity of the Building.  The determination of the appraisers
           will be limited solely to the issue of whether Lessor's or Lessee's
           submitted fair market rental rate for the leased area at issue is the
           closest to the actual fair market rental rate for such area as
           determined by appraisers, taking into account the requirements
           specified in Subparagraphs (a) and (b) above.  Each such appraiser
           will be appointed within fifteen (15) days after the Outside
           Agreement Date.

9504800R.OC1/DWW/K4933-002/05-17-95/meg



                         (ii)    The two (2) appraisers so appointed well 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 (2) appraisers.

                         (iii)   The three (3) appraisers will within thirty
           (30) days of the appointment of the third appraiser reach a decision
           as to whether the parties will use Lessor's or Lessee's submitted
           fair market rental rate, and will notify Lessor and Lessee thereof.

                         (iv)    The decision of the majority of the three (3)
           appraisers will be binding upon Lessor and Lessee.  If either Lessor
           or Lessee fails to appoint an appraiser within the time period
           specified in Subparagraph (c)(I) hereinabove, the appraiser appointed
           by one of them will, within thirty (30) days following the date on
           which the party failing to appoint an appraiser could have last
           appointed such appraiser, reach a decision based upon the procedures
           set forth above (i.e., by selecting either Lessor's or Lessee's
           submitted fair market rental rate) and notify Lessor and Lessee
           thereof, and such appraiser's decision will be binding upon Lessor
           and Lessee.

                         (v)     If the two (2) appraisers fail to agree upon
           and timely appoint a third appraiser, both appraisers will be
           dismissed and the matter to be decided will be forthwith submitted to
           arbitration under the provisions of the American Arbitration
           Association based upon the procedures set forth above (i.e., by
           selecting either Lessor's or Lessee's submitted fair market rental
           rate).

                         (vi)    The cost of appraisal (and, if necessary,
           arbitration) will be shared by Lessor and Lessee equally.

                         (vii)   If the process described in Subparagraph (b)
           above and this Subparagraph (c) has not resulted in a selection of
           Lessor's and Lessee's fair market rental rate by the commencement of
           the applicable lease term, then the fair market rental rate estimated
           by Lessor will be used until the appraiser(s) reach a decision, with
           an appropriate rental credit and other adjustments for any
           overpayments of Monthly Base Rent or other amounts if the appraisers
           select Lessee's estimate of the fair market rental rate.

                63.     Tenant Improvements.  Lessor shall install, at Lessor's
sole cost and expense. (i) one hundred and twenty (120) square yards of Oxford
Place carpet (with static control), over a new 3/8" commercial pad, throughout
the reception, stairway and top landing area only, and (ii) a 4" Roppe base.

                64.     Miscellaneous.

                        64.1    Waiver of Trial By Jury.  IN ANY ACTION OR
        PROCEEDING ARISING HEREFROM, LESSEE HERBY CONSENTS TO (I) THE
        JURISDICTION OF ANY COMPETENT COURT WITHIN THE STATE OF CALIFORNIA, (II)
        SERVICE OF PROCESS BY ANY MEANS AUTHORIZED BY CALIFORNIA LAW, AND (III)
        IN THE INTEREST OF SAVING TIME AND EXPENSE, TRIAL WITHOUT A JURY.

                        64.2    Rules and Regulations.  Lessee shall faithfully
        observe and comply with the rules and regulations that Lessor shall from
        time to time promulgate.  Lessor reserves the right from time to time in
        its discretion to make all reasonable additions and modifications to the
        rules and regulations.  Any additions and modifications to the rules and
        regulations shall be binding on Lessee when delivered to Lessee.
        Lessor's current rules and regulations are attached hereto as Exhibit B.
