<PAGE>   2
DEPOSIT

     5.   Lessee has deposited with Lessor $_______ as security for the full and
faithful performance of each and every term, provision, covenant and condition
of this Lease, including, but not limited to ???? payment of rent Lessor may
use, apply or retain the whole or any part of any part of such security for the
payment of any rent in default or for any other sum which Lessor may spend or be
required to spend by reason of Lessee's default. Should Lessee faithfully and
fully comply with all of the terms, provisions, covenants and conditions of this
Lease, the security of any balance thereof shall be returned to Lessee or, at
the option of Lessor, to the last assignee of Lessee's interest in this Lease at
the expiration of the term hereof. Lessee shall not be entitled to any interest
to any interest on said security deposit.


POSSESSION

     6.   If Lessor, for any reason whatsoever, cannot deliver possession of the
Premises to Lessee at the commencement of the said term, as hereinbefore
specified, this Lease shall not be void or voidable, nor shall Lessor, or
Lessor's agents, be liable to Lessee for any loss or damage resulting therefrom;
but in that event the commencement and termination dates of the Lease and all
other dates affected thereby shall be revised to conform to the date of Lessor's
delivery of possession. The above is, however, subject to the provision that the
period of delay of delivery of the Premises shall not exceed 45 days from the
commencement date herein. If the period of delay of delivery exceeds the
foregoing, Lessee, at his or its option, may declare this Lease null and void.

ACCEPTANCE OF PREMISES AND CONSENT TO SURRENDER

     7.   By entry hereunder, the Lessee accepts the Premises as being in good
and satisfactory condition. The Lessee agrees on the last day of the term
hereof, or on sooner termination of this Lease, to surrender the premises,
together with all alterations, additions, and improvements which may have been
made in, to, or on the Premises by Lessor or Lessee, unto Lessor in the same
good condition as at Lessee's entry into the Premises excepting for such wear
and tear as would be normal for the period of the Lessee's occupancy. The
Lessee, or before the end of the term or sooner termination of this Lease, shall
remove all Lessee's personal property and trade fixtures from the premises and
all property not so removed shall be deemed to be abandoned by the Lessee. If
the Premises be not surrendered at the end of the term or sooner termination of
this Lease, the Lessee shall indemnify the Lessor against loss or liability
resulting from delay by the Lessee in so surrendering the Premises including,
without limitation, any claims made by any succeeding tenant founded on such
delay. *See Addendum hereto.

USES PROHIBITED

     8.   Lessee shall not commit, or suffer to be committed, any waste upon the
Premises, or any nuisance, or other act or thing which may disturb the quiet
enjoyment of any other tenant in or around the buildings in which the Premises
may be located, or allow any sale by auction upon the Premises, or allow the
Premises to be used for any improper, immoral, unlawful or objectionable
purpose, or place any loads upon the floor, walls, or roof which endanger the
structure, or place any harmful liquids in the drainage system of the building.
No waste materials or refuse shall be dumped upon or permitted to remain upon
any part of the Premises outside of the building proper. No materials, supplies,
equipment, finished products or semi-finished products, raw materials or
articles of any nature shall be stored upon or permitted to remain on any
portion of the Premises outside of the buildings proper.

ALTERATIONS AND ADDITIONS

     9.   Except as hereinafter provided, the lessee shall make no alterations,
additions or improvements to the Premises or any part thereof without first
obtaining the prior written consent of the Lessor. The Lessor may impose as a
condition to the aforesaid consent such requirements as Lessor may deem
necessary in Lessor's sole discretion, including without limitation thereto, the
manner in which the work is done, a right of approval of the contractor by whom
the work is to be performed, the times during which it is to be accomplished,
and the requirement that upon written request of Lessor prior to the expiration
or earlier termination of the Lease, Lessee will remove any or all improvements
or additions to the Premises installed at Lessee's expense. All such
alterations, additions or improvements not specified to be removed shall at the
expiration of earlier termination of the lease become the property of the Lessor
and remain upon and be surrendered with the Premises. All movable furniture,
business and trade fixtures, and machinery and equipment shall remain the
property of the Lessee and may be removed by the Lessee at any time during the
Lease term when Lessee is not in default hereunder. Items which are not to be
deemed as movable furniture, business and trade fixtures, or machinery and
equipment shall include heating, lighting, electrical systems, air conditioning,
partitioning, carpeting, or any other installation which has become an integral
part of the Premises. The Lessee will at all times permit notices of
non-responsibility to be posted and to remain posted until the completion of
alterations or additions which have been approved by the Lessor. * See Addendum
hereto for supplemental provisions.

MAINTENANCE OF PREMISES

     10.  Lessee shall, at Lessee's sole cost, keep and maintain the Premises
and appurtenances and every part thereof, including but not limited to, glazing,
sidewalks, parking areas, plumbing, electrical systems, heating and air
conditioning installations, any store front, roof covering -- unless it is not
feasible to repair the existing roof covering and a new roof covering is
required, and the interior of the Premises in good order, condition, and repair.
Lessor at Lessor's sole cost and expense shall maintain the exterior of the
walls, and structural portions of the roof, foundations, walls, and floors
except for any repairs caused by the wrongful act of the Lessee and Lessee's
agents. The Lessor will replace the roof covering if repairs to said covering
are no longer economically feasible in the judgment of roofing experts, and
provided that said replacement is not made necessary by acts of the Lessee and
Lessee's agents. The Lessee shall water, maintain and replace, when necessary,
any shrubbery and landscaping provided by the Lessor on the Premises. The Lessee
expressly waives the benefits of any statute now or hereafter in effect which
would otherwise afford the Lessee the right to make repairs at Lessor's expense
or to terminate this lease because of Lessor's failure to keep the Premises in
good order, conditions or repair. Lessor shall not be obligated to paint the
exterior of the Premises.

FIRE AND EXTENDED COVERAGE INSURANCE AND SUBROGATION

ABANDONMENT

     12.  Lessee shall not vacate or abandon the Premises at any time during the
term; and if Lessee shall abandon, vacate or surrender the premises, or be
dispossessed by process of law, or otherwise, any personal property belonging to
Lessee and left on the premises shall be deemed to be abandoned, at the option
of Lessor, except such property as may be mortgaged to Lessor.

FREE FROM LIENS

     13.  Lessee shall keep the Premises and the property in which the Premises
are situated, free from any liens arising out of any work performed, materials
furnished, or obligations incurred by Lessee.


COMPLIANCE WITH GOVERNMENTAL REGULATIONS

     14.  Lessee shall, at his sole cost and expense, comply with all of the
requirements of all Municipal, State and Federal authorities now in force, or
which may hereafter be in force, pertaining to the Premises, and shall
faithfully observe in the use of the Premises all Municipal ordinances and State
and Federal statutes now in force or which may hereafter be in force. The
judgment of any court of competent jurisdiction, or the admission of Lessee in
any action or proceeding against Lessee, whether Lessor be a party thereto or
not, that Lessee has violated any such ordinances or statute in the use of the
Premises, shall be conclusive of that fact as between Lessor and Lessee.

INDEMNIFICATION OF LESSOR AND LESSEE'S LIABILITY INSURANCE

     15.  The Lessee, as a material part of the consideration to be rendered to
the Lessor, hereby waives all claims against the Lessor for damages to goods,
wares and merchandise, and all other personal property in, upon, or about the
Premises and for injuries to persons in or about the Premises, from any cause
arising at any time, excepting claims arising from the Lessor's negligence, and
the Lessee will hold the Lessor exempt and harmless from any damage or injury to
any person, or to the goods, wares and merchandise and all other personal
property of any person, arising from the use of the Premises by the Lessee, or
from the failure of the Lessee to keep the Premises in good condition and
repair, as herein provided.

                     SEE REVISED INSURANCE CLAUSE ATTACHED

ADVERTISEMENTS AND SIGNS

     16.  Lessee will not place or permit to be placed, in, upon or about the
Premises any unusual or extraordinary signs, or any signs not approved by the
city or other governing authority. The Lessee will not place, or permit to be
placed, upon the Premises, any signs, advertisements or notices without the
written consent of the Lessor first had and obtained. Any sign so placed on the
Premises shall be so placed upon the understanding and agreement that Lessee
will remove same as the termination of the tenancy herein created and repair any
damage or injury to the Premises caused thereby, and if not so removed by Lessee
then Lessor may have same so removed at Lessee's expense.

UTILITIES

     17.  Lessee shall pay for all water, gas, heat, light, power, telephone
service and all other service supplied to the Premises. If the premises are not
served by a separate water meter, the Lessee shall pay to the Lessor 100 percent
of the water bill for the entire property covered by said bill and of which the
Premises are a part.

ATTORNEY'S FEES

     18.  In case suit should be brought for the possession of the Premises, for
the recovery of any sum due hereunder, or because of the breach of any other
covenant herein, the losing party shall pay to the prevailing party a reasonable
attorney's fee, which shall be deemed to have accrued on the commencement of
such action and shall be enforceable whether or not such action is prosecuted to
judgment.

DEFAULT

     19.  * See Addendum hereto.

LATE CHARGES

     20.  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 on Lessor by the
terms of any mortgage or trust deed covering the Premises. Accordingly, if any
installment of rent or any other sum due from Lessee shall not be received by
Lessor or Lessor's designee within ten (10) days after such amount shall be due,
Lessee shall pay to Lessor a late charge equal to ten percent (10%) 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


                                     3 of 5
<PAGE>   4


Lessee's default with respect to such overdue amount, not prevent Lessor from
exercising any of the other rights and remedies granted hereunder.

SURRENDER OF LEASE

     21.  The voluntary or other surrender of this Lease by Lessee, or a mutual
cancellation thereof, shall not work a merger, and shall, at the option of
Lessor, terminate all or any existing subleases or subtenancies, or may, at the
option of Lessor, operate as an assignment to him of any or all such subleases
or subtenancies.

TAXES

     22.  The Lessee shall be liable for all taxes levied against personal
property and trade or business fixtures. The Lessee also agrees to pay, as
additional rental, during the term of this Lease and any extensions thereof, all
real estate taxes plus the yearly installments of any special assessments which
are of record or which may become a record during the term of this lease. If
said taxes and assessments are assessed against the entire building and building
site, and this Lease does not cover the entire building or building site, the
taxes and assessment installments allocated to the Premises shall be pro-rated
on a square footage or other equitable basis, as calculated by the Lessor. It is
understood and agreed that the Lessee's obligation under this paragraph will be
pro-rated to reflect the commencement and termination dates of this Lease.

NOTICES

     23.  All notices to be given to Lessee may be given in writing personally
or by depositing the same in the United States mail, postage prepaid, and
addressed to Lessee at the said Premises, whether or not Lessee has departed
from, abandoned or vacated the Premises, with a copy thereof to Lessee at P.O.
Box 21, Palo Alto, CA 94302.

ENTRY BY LESSOR

     24.  Lessee shall permit Lessor and his agents to enter into and upon the
Premises at all reasonable times for the purpose of inspecting the same or for
the purpose of maintaining the building in which the Premises are situated, or
for the purpose of making repairs, alterations or additions to any other portion
of said building, including the erection and maintenance of such scaffolding,
canopies, fences and props as may be required without any rebate of rent and
without any liability to Lessee for any loss of occupation or quiet enjoyment of
the Premises thereby occasioned; and shall permit Lessor and his agents, at any
time within ninety days prior to the expiration of this Lease, to place upon the
Premises any usual or ordinary "For Sale" or "To Lease" signs and exhibit the
Premises to prospective tenants at reasonable hours.

DESTRUCTION OF PREMISES

     25.  In the event of a partial destruction of the Premises during the said
term from any cause, Lessor shall forthwith repair the same, provided such
repairs can be made within ?? days under the laws and regulations of State,
Federal, County or Municipal authorities, but such partial destruction shall in
no way annul or void this Lease, except that Lessee shall be entitled to a
proportionate reduction of rent while such repairs are being made, such
proportionate reduction to be based upon the extent to which the making of such
repairs shall interfere with the business carried on by Lessee in the Premises.
If such repairs cannot be made in ?? days, Lessor may, at his option, make same
within a reasonable time, this Lease continuing in full force and effect and the
rent to be proportionately reduced as aforesaid in ?? days, or such repairs
cannot be made under such laws and regulations, this Lease may be terminated at
the option of either party. In respect to any partial destruction which Lessor
is obligated to repair or may elect to repair under the terms of this paragraph,
the provision of Section 1932, Subdivision 2, and of Section 1933, Subdivision
4, of the Civil Code of the State of California are waived by Lessee. In the
event that the building in which the Premises may be situated be destroyed to
the extent of not less than 33 1/3% of the replacement cost thereof, Lessor may
elect to terminate this Lease, whether the Premises be injured or not. A total
destruction of the building in which the Premises may be situated shall
terminate this Lease. In the event of any dispute between Lessor and Lessee
relative to the provisions of this paragraph, they shall each select an
arbitrator, the two arbitrators so selected shall select a third arbitrator and
the three arbitrators so selected shall hear and determine the controversy and
their decision thereon shall be final and binding upon both Lessor and Lessee,
who shall bear the cost of such arbitration equally between them.

ASSIGNMENT AND SUBLETTING

     26.  *See Addendum hereto.

CONDEMNATION

     27.  If any part of the premises shall be taken for any public or
quasi-public use, under any statute or by right of eminent domain or private
purchase in lieu thereof, and a part thereof remains which is susceptible of
occupation hereunder, this Lease shall, as to the part so taken, terminate as of
the date title shall vest in the condemnor or purchase, and the rent payable
hereunder shall be adjusted so that the Lessee shall be required to pay for the
remainder of the term only such portion of such rent as the value of the part
remaining after such taking bears to the value of the entire

                                     4 of 5
<PAGE>   5
Premises prior to such taking; but in the event Lessor shall have the option to
[ILLEGIBLE] title to the part so taken vests in the condemnor or purchaser. If
all of the premises, or a part thereof be taken so that there does not remain a
portion susceptible for occupation hereunder, this Lease shall thereupon
terminate. If a part or all of the Premises be taken, all compensation awarded
upon such taking shall go to the Lessor and the Lessee shall have no claim
thereto.

EFFECT OF CONVEYANCE

     28. The term "Lessor" as used in this Lease, means only the owner for the
time being of the land and building containing the Premises, so that, in the
event of any sale of said land or building, or in the event of a lease of said
building, the Lessor shall be and hereby is entirely freed and relieved of all
covenants and obligations of the Lessor hereunder, and it shall be deemed and
construed, without further agreement between the parties and the purchase at any
such sale, or the Lessee of the building, that the purchaser or lessee of the
building has assumed and agreed to carry out any and all covenants and
obligations of the Lessor hereunder. If any security be given by the Lessee to
secure the faithful performance of all or any of the covenants of this Lease on
the part of the Lessee, the Lessor may transfer and deliver the security, as
such, to the purchaser at any such sale or the [ILLEGIBLE] of the building, and
thereupon the Lessor shall be discharged from any further liability in reference
thereto.

SUBORDINATION

     29. Lessee agrees that this Lease may, at the option of Lessor, be subject
and subordinate to any mortgage, deed of trust or other instrument of security
which has been or shall be placed on the land and building or land or building
of which the Premises form a part, and this subordination is hereby made
effective without any further act of Lessor. The Lessee shall, at any time
hereinafter, on demand, execute any instruments, releases, or other documents
that may be required by any mortgagee, mortgagor, or trustor or beneficiary
under any deed of trust for the purpose of subjecting and subordinating this
Lease to the lien of any such mortgage, deed of trust or other instrument of
security, and the failure of the Lessee to execute such instruments, releases or
documents, shall constitute a default hereunder.

WAIVER

     30. The waiver by Lessor of any breach of any term, covenant or condition,
herein contained shall not be deemed to be a waiver of such term, covenant or
condition or any subsequent breach of the same or any other term, covenant or
condition therein contained. The subsequent acceptance of rent hereunder by
Lessor shall not be deemed to be a waiver of any preceding breach by Lessee of
any term, covenant or condition of this Lease, other than the failure of Lessee
to pay the particular rental so accepted, regardless of Lessor's knowledge of
such preceding breach at the time of acceptance of such rent.

HOLDING OVER

     31. Any holding over after the expiration of the said term, with the
consent of Lessor, shall be construed to be a tenancy from month to month, at a
rental to be negotiated by Lessor and Lessee prior to the expiration of said
term, and shall otherwise be on the terms and conditions herein specified, so
far as applicable.

SUCCESSORS AND ASSIGNS

     32. The covenants and conditions herein contained shall, subject to the
provisions as to assignment, apply to and bind the heirs, successors, executors,
administrators and assigns of all of the parties hereto; and all of the parties
hereto shall be jointly and severally liable hereunder.

TIME

     33. Time is of the essence of this Lease.

MARGINAL CAPTIONS

     34. The marginal headings or titles to the paragraphs of this Lease are not
a part of this Lease and shall have no effect upon the construction or
interpretation of any part thereof. This instrument contains all of the
agreements and conditions made between the parties hereto and may not be
modified orally or in any other manner than by an agreement in writing signed by
all of the parties hereto or their respective successors in interest.

                               ADDENDUM TO LEASE

     This Addendum to the attached Lease by and between JORGE A. LOVATO, JR. &
ROBIN E. LOVATO, husband and wife, as Lessor, and THOITS BROS., INC., a
California corporation, as Lessee, demising the property numbered 190 Cochrane
Circle, Morgan Hill, California (the "Premises"), is hereby amended by the
following provisions:

     1.   ALTERATIONS AND ADDITIONS

     Notwithstanding the provisions of Paragraph 9 of the Lease, Lessee may
make nonstructural alterations, additions or improvements to the interior of
the Premises without Lessor's consent and, similarly, in connection therewith
may make structural alterations, additions, or improvements to the Premises
without Lessor's consent provided the cost of such structural work does not
exceed Fifty Thousand Dollars ($50,000.00). Whether or not Lessor's consent
is required, Lessee will remove any such improvements or additions upon
Lessor's written request prior to expiration or sooner termination of the
Lease. Except for this modification, the provisions of Paragraph 9 of the Lease
shall prevail.

     Lessee shall provide Lessor with at least five (5) days prior written
notice of intent to commence any work to allow Lessor to post an appropriate
notice of non-responsibility.

     Any of said alterations, additions and improvements shall be performed by a
licensed contractor or contractors in accordance with all applicable ordinances
and regulations and, if required, under permit or permits issued by the
governmental agency having jurisdiction thereof.

     2.   FIRE AND EXTENDED COVERAGE INSURANCE AND SUBROGATION

     Paragraph 11 of the Lease is amended by deleting the text in the Lease
form and substituting the following therefor:

          11.  Lessee shall not use, or permit the Premises, or any part
thereof, to be used, for any purpose other than that for which the Premises are
hereby leased; and no use shall be made or permitted to be made on the
Premises, nor acts alone, which will cause a cancellation of any insurance
policy covering said building, or any part thereof, nor shall Lessee sell or
permit to be kept, used or sold, in or about the Premises, any article which
may be prohibited by the standard form of fire insurance policies. Lessee
shall, at his sole cost and expense, comply with any and all requirements
pertaining to the Premises, of any insurance organization or company, necessary
for the maintenance of

                                       1
<PAGE>   7
reasonable fire and public liability insurance, covering said building and
appurtenances.

          11.1 Lessee, shall at its expense, obtain and keep in force during
the term of this Lease a policy of comprehensive public liability insurance
insuring Lessee, Lessor, and any third parties named by Lessor which may
include Lessor's lender, against any liability arising out of the condition,
use, occupancy or maintenance of the Premises. Such insurance policy shall have
a combined single limit for both bodily injury and property damage in an amount
not less than Two Million No/100th Dollars ($2,000,000.00). The limits of said
insurance shall not limit the liability of Lessee hereunder. Additional
premiums, if any, resulting from insuring any third parties' named by Lessor
shall be borne by Lessor, other than Lessor's lender.

          11.2 Lessee shall, at its expense, keep in force during the term of
this Lease, a policy of fire and property damage insurance in an "all risk"
form with a sprinkler leakage endorsement, insuring Lessee's inventory,
fixtures, equipment and personal property within the Premises for the full
replacement value thereof.

          11.3 Lessor shall maintain a policy or policies of fire and property
damage insurance in an "all risk" form, with sprinkler covering loss or damage
to the building, including Lessee's leasehold improvements installed with the
written consent of the Lessor, in such amounts and with such coverage as Lessor
deems advisable.

          11.4 Lessee shall pay to Lessor as additional rent, during the term
hereof, upon receipt of an invoice therefore 100% of the premiums for any
insurance obtained by Lessor pursuant to 11.3 above. Lessor may obtain such
insurance for the Building separately, or together with other buildings and
improvements which Lessor elects to insure together under blanket policies of
insurance. In such case Lessee shall be liable for only such portion of the
premiums for such blanket policies as are allowable to the Premises. It is
understood and agreed that Lessee's obligation under this paragraph shall be
prorated to reflect the Commencement Date and Expiration Date of the Lease.

          11.5 Lessee and Lessor each hereby waives any and all rights of
recovery against the other, or against the officers, directors, employees,
partners, agents and representatives of the other, for loss of or damage to the
property of the waiving party or the property of others under its control, to
the extent such loss or damage is insured against under any insurance policy
carried by Lessor or Lessee hereunder. Each party shall notify their respective
insurance carriers of this waiver.

     3.   COMPLIANCE WITH GOVERNMENTAL REGULATIONS

     Paragraph 14: If Lessee is required to modify any portion of the Premises
in order to comply with Americans With Disabilities Act and the requirement is
not directly related to and occasioned by alterations, additions or
improvements to the Premises being undertaken by Lessee, then the cost of such
compliance with the Americans With Disabilities Act unrelated to Lessee's work
shall be paid by Lessee, but upon expiration or sooner termination of the
Lease, Lessor shall reimburse Lessee for a portion of the cost thereof
determined as follows: The depreciable life of the improvements to the Premises
resulting from said compliance with the Americans With Disabilities Act shall
be determined under the depreciation schedules provided under Regulations of
the Internal Revenue Service. Lessor shall reimburse to Lessee the portion of
the costs of such compliance equivalent to the percentage of the depreciable
life thereof remaining following the date of termination or sooner expiration
of the Lease.

     4.   DEFAULT

     The provisions of Paragraph 19 of the Lease shall be deemed deleted
therefrom and the following substituted therefor:

          19.  DEFAULT. In the event Lessee shall default in the payment of any
monetary obligation to be paid by Lessee hereunder, including without
limitation, the payment of any rentals, taxes, insurance and/or any monetary
obligation owing Lessor as a result of Lessor curing a default of Lessee
provided herein, Lessor shall so notify Lessee in writing, and failure of
Lessee to cure such default within five (5) days after receipt of such notice
shall, at the option of Lessor, entitle (but not obligate) Lessor to terminate
this Lease, or Lessor may enforce performance in any performance of any of the
terms or provisions of this Lease other than the payment of monetary
obligations owing by Lessee, Lessor shall promptly so notify Lessee in writing.
If Lessee shall fail to cure such default within thirty (30) days after receipt
of such notice, or if the default is of such character as to require more than
thirty (30) days to cure and Lessee shall fail to commence to do so within
thirty (30) days after receipt to such notice and thereafter diligently proceed
to cure such default, then Lessor may, in addition to any other rights or
remedies available to Lessor, terminate this Lease, or upon ten (10) days
written notice to Lessee, without waiving or releasing Lessee from any
obligation under this Lease, perform the obligation(s) of Lessee. All sums paid
by Lessor in curing Lessee's non-monetary defaults (including, without
limitation, all penalties, interest costs and attorneys' fees in connection
therewith) shall be due and payable by Lessee to Lessor as additional rent upon
demand.

            (a) LESSOR'S DAMAGES FOLLOWING TERMINATION FOR LESSEE DEFAULT.
Should Lessor terminate the Lease as a result of Lessee's default, Lessor may
recover from Lessee:

                  (1) The worth at the time of the award of any unpaid rent and
which had been earned at the time of termination; plus

                  (2) The worth at the time of award of the amount by which the
unpaid rent would have been earned after termination until the time of award
exceeds the amount of such rental loss that Lessee proves could have been
reasonably avoided; plus

                  (3) The worth at the time of award of the amount by which the
unpaid rent for the balance of the lease term after the time of award exceeds
the amount of such rental loss that Lessee proves could be reasonably avoided;
plus

                  (4) Any other amounts necessary to compensate Lessor for
detriment proximately caused by the default by Lessee or which in the ordinary
course of events would likely result, including without limitation the
reasonable costs and expenses incurred by Lessor in:

                        (a) Retaking possession;

                        (b) Cleaning and making repairs and alterations
necessary to return the Premises to good condition and preparing the premises
for reletting;

                        (c) Removing, transporting, and storing any of Lessee's
property left at the Premises (although Lessor shall have no obligation to
remove, transport or store any of the property); and

                        (d) Reletting the Premises, including reasonable
brokerage commissions, advertising costs and attorneys' fees.

      The "worth at the term of award" of the amounts referred to in
subparagraphs (1) and (2) of this subparagraph (a) is computed by allowing
interest at a rate equal to the Lessee of ten percent (10%) per annum or the
maximum rate permitted by law. The "worth at the time of award" of the amount
referred to in subparagraph (3) of this subparagraph (a) shall be computed by
discounting such amount at the discount rate of the Federal Reserve Bank of San
Francisco at the time of the award plus one percent.

            (b) Upon default by Lessee and unless and until Lessor elects to
terminate this Lease, this Lease shall continue in


                                       4
<PAGE>   10
effect after the default and Lessor may enforce all rights and remedies under
this Lease, including the right to recover the rent as it becomes due under the
Lease. This provision is intended to provide Lessor with the remedy contained
in Civil Code Section 1951.4 and any amendments thereto or successor statute(s).

               (c)  In the term Lessor shall default in the performance of any
of the terms or provisions of this Lease, Lessee shall promptly so notify Lessor
in writing. If Lessor shall fail to cure such default within thirty (30) days
after receipt of such notice, or if the default is of such character as to
require more than thirty (30) days after receipt of such notice and thereafter
diligently proceed to cure such default, then, in either such event, Lessee may
cure such default and such expense shall be deducted from the rent otherwise
due, or cancel and terminate this Lease.

     5.   ASSIGNMENT AND SUBLETTING.

     Paragraph 26 of the Lease shall be deemed deleted therefrom and the
following substituted therefor:

          26.  ASSIGNMENT AND SUBLETTING.  Lessee shall not voluntarily sell,
assign, or transfer all or any part of Lessee's interest in this Leases or in
the Premises or any part thereof, sublease all or any part of the Premises, or
permit all or any part of the Premises to be used by any person or entity other
than Lessee or Lessee's employees, guests or invitees, except as specifically
provided in this Lease. The parties agree that the Lease is not intended to
allow Lessee to unreasonably profit by a future transfer of this Lease or the
right to use or occupy the Premises. In order to carry out this intent, if
Lessee assigns its interest in the Lease or subleases the Premises in accordance
with this paragraph, then Lessee shall pay to the Lessor, as additional rent
hereunder, eighty percent (80%) of the net consideration received on account of
such assignment or, eighty percent (80%) of rents received by Lessee which are
in excess of the amounts payable by Lessee to Lessor hereunder, each of said
amounts to be determined after deducting Lessee's costs of such assignment or
subletting, including without limitation, real estate commissions, reasonable
legal fees and alterations of the premises, if any, required by the assignee or
sublessee as a condition of accepting the assignment or entering into the
sublease. Such consideration shall be payable on the same basis, whether
periodic or lump sum, that such consideration is paid to Lessee. Any such
assignment, subletting or transfer of Lessee's interest shall be completed as
follows:

               a)   Lessee shall, by written notice, advise Lessor of Lessee's
desire on a stated date (which date shall not be less than thirty (30) days nor
more than ninety (90) days after the date



                                       5
<PAGE>   11
of Lessee's notice) to assign this lease or to sublet all or any part of the
Premises for any part of the Lease Term. Lessee's notice shall state the name,
legal composition and address of the proposed assignee or sublessee, and Lessee
shall provide the following information to Lessor with said notice: a true and
complete copy of the proposed assignment agreement or sublease; a financial
statement of the proposed assignee or sublessee prepared in accordance with
generally accepted accounting principles within one year prior to the proposed
effective date of the assignment or sublease; the nature of the proposed
assignee's or sublessee's business to be carried on in the Premises; the
payments to be made or other consideration to be given on account of the
assignment or sublease; and such other pertinent information as may be
requested by Lessor, all in sufficient detail to enable Lessor to evaluate the
proposed assignment or sublease and the prospective assignee or sublessee.
Lessee's notice shall not be deemed to have been served or given until such
time as Lessee has provided Lessee with all information reasonably requested by
Lessor pursuant to this paragraph. Lessee shall immediately notify Lessor of
any modification to the proposed terms of such assignment or sublease.

     b)   As long as Lessee is not in default under any of the terms, covenants
or conditions of this Lease on Lessee's part to be observed or performed,
Lessor agrees not to unreasonably withhold Lessor's consent to the proposed
assignment or subletting, on the terms and conditions specified in said notice.
Without otherwise limiting the criteria upon which Lessor may withhold its
consent to any proposed assignment or sublease, Lessor may withhold its consent
where Lessee is in default at the time of the giving of Lessee's notice or at
any time thereafter; where the net worth of the proposed assignee or sublessee
(according to generally accepted accounting principles) is less than eighty
percent (80%) of the book value net worth of Lessee at the time this Lease is
executed; or Lessor reasonably believes that the proposed assignee or
sublessee's use of the Premises may increase the risk of contamination of the
Premises by "hazardous substances or materials" or the violation of any
hazardous materials laws. Any assignment or subletting without Lessor's consent
as set forth above shall be voidable at Lessor's option, and shall constitute a
default by Lessee. Lessor's consent to any one assignment or sublease shall not
constitute a waiver of the provisions of this paragraph as to any subsequent
assignment or sublease nor a consent to any subsequent assignment or sublease.
Any assignment or sublease as provided herein, shall not release Lessee from
Lessee's primary liability under this Lease and Lessee shall remain jointly and
severally liable with the assignee or sublessee.

     c)   In the event Lessor consents to any assignment, such consent shall be
conditioned upon the assignee expressly assuming and agreeing to be bound by
each of Lessee's covenants, agreements and obligations (including, without
limitation, the



                                       6
<PAGE>   12
obligation to pay all rent and additional rent) contained in this Lease and
written assignment and assumption agreement in a form approved and executed by
Lessor. In the event Lessor consents to a proposed assignment or sublease, such
assignment or sublease shall be valid and the assignee or sublessor shall have
the right to take possession of the Premises (or applicable portion thereof)
only if an executed original of the assignment or sublease is delivered to
Lessor.

          d)   Lessee hereby irrevocably gives to and confers upon Lessor, as
security for Lessee's obligations under this Lease, the right, power and
authority to collect all rents from any assignee or sublessee of all or any part
of the Premises as permitted by this Paragraph 26, or otherwise, and Lessor, as
assignee of Lessee, or a receiver for Lessee appointed on Lessor's application,
may collect such rent and apply it toward Lessee's obligations under this Lease;
provided, however, that until the occurrence of any default by Lessee, Lessee
shall have the right to collect such rent. Upon the occurrence of any default by
Lessee, Lessor may at any time without notice in Lessor's own name sue for or
otherwise collect such rent, including rent past due and unpaid, and apply the
same, less costs and expenses of operation and collection, including reasonable
attorneys' fees, toward Lessee's obligations under this Lease. Lessor's
collection of such rents shall not constitute an acceptance by Lessor of
attornment by such sublessors; in the event of a default by Lessee, Lessor shall
have all rights provided by this Lease and by law, and Lessor may, upon re-entry
and taking possession of the Premises, eject all parties in possession or eject
some and not others, or eject none, as Lessor shall determine in Lessor's sole
discretion.

          e)   Lessee expressly agrees that the provisions of this paragraph are
not unreasonable standards or conditions for purposes of Section 1951.4(b)(2) of
the California Civil Code, as amended from time to time. Lessee shall pay, as
additional rent, Lessor's reasonable attorney's fees for reviewing,
investigating, processing and/or documenting any requested assignment or
sublease, whether or not Lessor's consent is granted. No interest of Lessee in
this Lease shall be assignable by operation of law, including, without
limitation, the transfer of this Lease by bankruptcy, testacy or intestacy. The
provisions of Paragraph 26 expressly applies to all heirs, successors,
sublessees, assignees and transferees of Lessee.

     6.   CERTIFICATE OF ESTOPPEL

     The provisions of paragraph 41 of the Lease shall be deemed replaced by the
following:

     41.  CERTIFICATE OF ESTOPPEL Each party shall, within ten (10) days after
receiving a written request therefore, execute


                                       7
<PAGE>   13
and deliver to the other party, in recordable form, a certificate stating that
the Lease is unmodified and in full force and effect, or in full force and
effect as modified and stating the modifications. The certificate shall also
state the amount of the monthly rent, that date to which monthly rent has been
paid in advance, the amount of the security deposit and/or prepaid monthly rent,
and shall include such other items as either party, or such party's lender, may
reasonably request. Failure to deliver such certificate within such time shall
constitute a conclusive acknowledgement by the party failing to deliver the
certificate that the Lease is in full force and effect and has not been modified
except as may be represented by the party requesting the certificate. Any such
certificate requested by Lessor may be conclusively relied upon by any
prospective purchaser or encumbrancer of the Premises.

     7.   ATTORNMENT TO LENDER

     The provisions of paragraph 42 of the Lease shall be deemed replaced by the
following:

          42.  ATTORNMENT TO LENDER. In the event the interest of Lessor in the
Premises (whether such interest of Lessor is a fee title interest or a leasehold
interest) is encumbered by deed of trust, and such interest is acquired by a
lender or any other third party through judicial foreclosure or by exercise of
power of sale at private trustee's judicial foreclosure sale, Lessee hereby
agrees to attorn to the purchaser at any such foreclosure sale and to recognize
such purchaser as the Lessor under this Lease, upon the condition that Lessee's
leasehold interest is recognized by the attorney and that Lessee shall be
entitled to remain in occupancy of the Premises under the Lease so long as
Tenant fulfills its obligations thereunder.

     8.   OPTION

     Lessee shall have an option to purchase the leased property exercisable on
or after January 1, 1996, under the Option Agreement entered into by Lessor and
Lessee contemporaneously with the execution of this Lease.

     9.   PROPOSED SUBLEASE

     Lessor and Lessee acknowledge that Lessee intends to sublease the Premises
to CIDCO, a Delaware corporation, pursuant to the Sublease Agreement approved by
Lessor, and Lessor hereby consents to said proposed sublease only on the terms
and conditions set forth therein.


                                       8
<PAGE>   14
      10.   HAZARDOUS WASTE

      Without Lessor's advance written consent, Lessee shall not bring, use or
permit upon the leased Premises, temporarily or otherwise, or generate at, or
emit any toxic or hazardous substances, including, without limitation,
substances or materials which are listed on any of the Environmental Protection
Agency's lists of hazardous wastes or identified in any statute or regulation
of the State of California dealing with Hazardous wastes as the same may be
amended from time to time. Notwithstanding Lessor's consent, Lessee shall
comply, at its sole cost, with all laws pertaining to, and shall indemnify and
hold Lessor harmless from any claims, liabilities, costs or expenses incurred
or suffered by Lessor, arising from such bringing, using, permitting,
generating, or emitting or disposing. Lessee's indemnification and hold
harmless obligations include, without limitations, (i) claims, liability, costs
or expenses resulting from or based upon administrative or judicial (civil or
criminal) action brought by and any private or public person under common law
or under any Federal, State, County or Municipal law, ordinance or regulation,
(ii) claims, liabilities costs or expenses pertaining to the clean-up or
containment of wastes, the identification of the pollutants or the waste, the
identification of scope or any environments contamination, the removal of
pollutants from soils, river beds or aquifers, the provision of an alternative
public drinking water source, or the long-term monitoring of ground water and
surface water, and (iii) all costs of defending such claims.

      11.   Paragraph 7 of the Lease is amended by adding the following
paragraph thereto: "Lessor makes no representation or warranties with respect
to the compliance of the Premises with any and all statutes, ordinances, rules,
regulations, zoning or use permits applicable to the Premises. Lessor shall
deliver the Premises to Lessee in an 'as-is,' where-is condition with all of
Lessor's inventory and personal property removed prior to delivery of
possession."


Lessor:                                   Lessee:
