2. PREMISES.

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

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

      2.3 COMPLIANCE WITH COVENANTS, RESTRICTIONS AND BUILDING CODE. Lessor
warrants to Lessee that the improvements on the Premises comply with all
applicable covenants or restrictions of record and applicable building codes,
regulations and ordinances in effect on the Commencement Date. Said warranty
does not apply to the use to which Lessee will put the Premises or to any
Alterations or Utility Installations (as defined in Paragraph 7.3(a)) made or to
be made by Lessee. If the Premises do not comply with said warranty, Lessor
shall, except as otherwise provided in this Lease, promptly after receipt of
written notice from Lessee setting forth with specificity the nature and extent
of such non-compliance, rectify the same at Lessor's expense. If Lessee does not
give Lessor written notice of a non-compliance with this warranty within six (6)
months following the Commencement Date, correction of that compliance shall be
the obligation of the Lessee at Lessee's sole cost and expense.

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

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

3. TERM.

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


<PAGE>

ADDENDUM "A" to the contract (Standard Industrial/Commercial Single-Tenant Lease
- Net) dated June 26, 1995 covering the premises commonly known as 2130 Research
Drive, Livermore, CA 94550 between FORMFACTOR, INC., as Lessee and PAUL E.
IACONO as Lessor.

      3.2 EARLY POSSESSION. If Lessee totally or partially occupies the Premises
prior to the Commencement Date, the obligation to pay Base Rent shall be abated
for the period of such early possession. All other terms of this Lease, however
(including but not limited to the obligations to pay Real Property Taxes and
insurance premiums and to maintain the Premises) shall be in effect during such
period. Any such early possession shall not affect nor advance the Expiration
Date of the Original Term.

      3.3 DELAY IN POSSESSION. If for an reason Lessor cannot deliver possession
of the Premises to Lessee as agreed herein by the Early Possession Date, if one
is specified in Paragraph 1.4, or, if no Early Possession Date is specified, by
the Commencement Date, Lessor shall not be subject to any liability therefor,
nor shall such failure affect the validity of this Lease, or the obligations of
Lessee hereunder, or extend the term hereof, but in such case, Lessee shall not,
except as otherwise provided herein, be obligated to pay rent or perform any
other obligation of Lessee under the terms of this Lease until Lessor delivers
possession of the Premises to Lessee. If possession of the Premises is not
delivered to Lessee within sixty (60) days after the Commencement Date, Lessee
may, at its option, by notice in writing to Lessor within ten (10) days
thereafter, cancel this Lease, in which event the Parties shall be discharged
from all obligations hereunder; provided, however, that if such written notice
by Lessee is not received by Lessor within said ten (10) days period, Lessee's
right to cancel this Lease shall terminate and be of no further force or effect.
Except as may be otherwise provided, and regardless of when the term actually
commences, if possession is not tendered to Lessee when required by this Lease
and Lessee does not terminate this Lease, as aforesaid, the period free of the
obligation to pay Base Rent, if any, that Lessee would otherwise have enjoyed
shall run from the date of delivery of possession and continue for a period
equal to what Lessee would otherwise have enjoyed under the terms hereof, but
minus any days of delay caused by the acts, changes or omissions of Lessee.

4. RENT.

      4.1 BASE RENT. Lessee shall cause payment of Base Rent and other rent or
charges, as the same may be adjusted from time to time, to be received by Lessor
in lawful money of the United States, without offset or deduction, on or before
the day on which it is due under the terms of this Lease. Base Rent and all
other rent and charges for any period during the term hereof which is for less
than one (1) full calendar month shall be prorated based upon the actual number
of days of the calendar month involved. Payment of Base Rent and other charges
shall be made to Lessor at its address stated herein or to such other persons or
at such other addresses as Lessor may from time to time designate in writing to
Lessee.

5. SECURITY DEPOSIT. Lessee shall deposit with Lessor upon execution hereof the
Security Deposit set forth in Paragraph 1.7 as security for Lessee's faithful
performance of Lessee's obligations under this Lease. If Lessee fails to pay
Base Rent or other rent charges due hereunder, or otherwise Defaults under this
Lease (as defined in Paragraph 13.1), Lessor may use, apply or retain all or any
portion of said Security Deposit for the payment of any amount due Lessor or to
reimburse or compensate Lessor for any liability, cost, expense, loss or damage
(including attorney's fees) which Lessor may suffer or incur by reason thereof.
If Lessor uses or applies all or any portion of said Security Deposit, Lessee
shall within ten (10) days after written request therefor deposit moneys with
Lessor sufficient to restore said Security Deposit to the full amount required
by this Lease. Any time the Base Rent increases during the term of this Lease,
Lessee shall, upon written request from Lessor, deposit additional moneys with
Lessor sufficient to maintain the same ratio between the Security Deposit and
the Base Rent as those amounts are specified in the Basic Provisions. Lessor
shall not be required to keep all or any part of the Security Deposit separate
from its general accounts. Lessor shall, at the expiration or earlier
termination of the term hereof and after Lessee has vacated the Premises, return
to Lessee (or, at Lessor's option, to the last assignee, if any, of Lessee's
interest herein), that portion of the Security Deposit not used or applied by
Lessor. Unless otherwise expressly agreed in writing by Lessor, no part of the
Security Deposit shall be considered to be held in trust, to bear interest or
other increment for its use, or to be prepayment for any moneys to be paid by
Lessee under this Lease.

6. USE.

      6.1 USE. Lessee shall use and occupy the Premises only for the purposes
set forth in Paragraph 1.8, or any other use which is comparable thereto, and
for no other purpose. Lessee shall not use or permit the use of the Premises in
a manner that creates waste or a nuisance, or that disturbs owners and/or
occupants of, or causes damage to, neighboring premises or properties. Lessor
hereby agrees to not unreasonably withhold or delay its consent to any written
request by Lessee, Lessee's assignees or subtenants, and by prospective
assignees and subtenants of the Lessee, its assignees and subtenants, for a
modification of said permitted purpose for which the Premises may be used or
occupied, so long as the same will not impair

IACONO as Lessor.

the structural integrity of the improvements on the Premises, the mechanical or
electrical systems therein, is not significantly more burdensome to the Premises
and the improvements thereon, and is otherwise permissible pursuant to this
Paragraph 6. If Lessor elects to withhold such consent, Lessor shall within five
(5) business days give a written notification of same, which notice shall
include an explanation of Lessor's reasonable objections to the change in use.

      6.2 HAZARDOUS SUBSTANCES.

            (a) REPORTABLE USES REQUIRE CONSENT. The term "HAZARDOUS SUBSTANCE"
as used in this Lease shall mean any product, substance, chemical, material or
waste whose presence, nature, quantity and/or intensity of existence, use,
manufacture, disposal, transportation, spill, release or effect, either by
itself or in combination with other materials expected to be on the Premises, is
either : (i) potentially injurious to the public health, safety or welfare, the
environment or the Premises, (ii) regulated or monitored by any governmental
authority, or (iii) a basis for liability of Lessor to any governmental agency
or third party under any applicable statute or common law theory. Hazardous
Substance shall include, but not be limited to, hydrocarbons, petroleum,
gasoline, crude oil or any products, by-products or fractions thereof. Lessee
shall not engage in any activity in, on or about the Premises which constitutes
a Reportable Use (as hereinafter defined) of Hazardous Substances without the
express prior written consent of Lessor and compliance in a timely manner (at
Lessee's sole cost and expense) with all Applicable Law (as defined in Paragraph
6.3). "REPORTABLE USE" shall mean (i) the installation or use of any above or
below ground storage tank, (ii) the generation, possession, storage, use,
transportation, or disposal of a Hazardous Substance that requires a permit
from, or with respect to which a report, notice, registration or business plan
is required to be filed with, any governmental authority. Reportable Use shall
also include Lessee's being responsible for the presence in, on or about the
Premises of a Hazardous Substance with respect to which any Applicable Law
requires that a notice be given to persons entering or occupying the Premises or
neighboring properties. Notwithstanding the foregoing, Lessee may, without
Lessor's prior consent, but in compliance with all Applicable Law, use any
ordinary and customary materials reasonably required to be used by Lessee in the
normal course of Lessee's business permitted on the Premises, so long as such
use is not a Reportable Use and does not expose the Premises or neighboring
properties to any meaningful risk of contamination or damage or expose Lessor to
any liability therefor. In addition, Lessor may (but without any obligation to
do so) condition its consent to the use or presence of any Hazardous Substance,
activity or storage tank by Lessee upon Lessee's giving Lessor such additional
assurances as Lessor, in its reasonable discretion, deems necessary to protect
itself, the public, the Premises and the environment against damage,
contamination or injury and/or liability therefrom or therefor, including, but
not limited to, the installation (and removal on or before Lease expiration or
earlier termination) of reasonably necessary protective modifications to the
Premises (such as concrete encasements) and/or the deposit of an additional
Security Deposit under Paragraph 5 hereof.

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

            (c) INDEMNIFICATION. Lessee shall indemnify, protect, defend and
hold Lessor, its agents, employees, lenders and ground lessor, if any, and the
Premises, harmless from and against any and all loss of rents and/or damages,
liabilities, judgments, costs, claims, liens, expenses, penalties, permits and
attorney's and consultant's fees arising out of or involving any Hazardous
Substance or storage tank brought onto the Premises by or for Lessee or under
Lessee's control. Lessee's obligations under this Paragraph 6 shall include, but
not be limited to, the effects of any contamination or injury to person,
property or the environment created or suffered by Lessee, and the cost of
investigation (including consultant's and attorney's fees and testing), removal,
remediation, restoration and/or abatement thereof, or of any contamination
therein involved, and shall survive the expiration or earlier termination of
this Lease. No termination, cancellation or release agreement entered into by
Lessor and Lessee shall release Lessee from its obligation under this Lease with
respect to Hazardous Substances or storage tanks, unless specifically so agreed
by Lessor in writing at the time of such agreement.

IACONO as Lessor.

      6.3 LESSEE'S COMPLIANCE WITH LAW. Except as otherwise provided in this
Lease, Lessee shall, at Lessee's sole cost and expense, fully, diligently and in
a timely manner, comply with all "APPLICABLE LAW," which term is used in this
Lease to include all laws, rules, regulations, ordinances, directives,
covenants, easements and restrictions of record, permits, the requirements of
any applicable fire insurance underwriter or rating bureau, and the
recommendations of Lessor's engineers and/or consultants, relating in any manner
to the Premises (including but not limited to matters pertaining to (i)
industrial hygiene, (ii) environmental conditions on, in, under or about the
Premises, including soil and groundwater conditions, and (iii) the use,
generation, manufacture, production, installation, maintenance, removal,
transportation, storage, spill or release of any Hazardous Substance or storage
tank), now in effect or which may hereafter come into effect, and whether or not
reflecting a change in policy from any previously existing policy. Lessee shall,
within five (5) days after receipt of Lessor's written request, provide Lessor
with copies of all documents and information, including, but not limited to,
permits, registrations, manifests, applications, reports and certificates,
evidencing Lessee's compliance with any Applicable Law specified by Lessor, and
shall immediately upon receipt, notify Lessor in writing (with copies of any
documents involved) of any threatened or actual claim, notice, citation,
warning, complaint or report pertaining to or involving failure by Lessee or the
Premises to comply with any Applicable Law.

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

or released in, on, under or about the Premises (including through the plumbing
or sanitary sewer system) and shall promptly, at Lessee's expense, take all
investigatory and/or remedial action reasonably recommended, whether or not
formally ordered or required, for the cleanup of any contamination of, and for
the maintenance, security, and/or monitoring of the Premises, the elements
surrounding same, or neighboring properties, that was caused or materially

            (b) Lessee shall, at Lessee's sole cost and expense, procure and

the Premises), it is intended by the Parties hereto that Lessor have no
obligation, in any manner whatsoever, to repair and maintain the Premises, the
improvements located thereon, or the equipment therein, whether structural or
non structural, all of which obligations are intended to be that of the Lessee
under Paragraph 7.1 hereof. It is the intention of the Parties that the terms of
this Lease govern the respective obligations of the Parties as to maintenance
and repair of the Premises. Lessee and Lessor expressly waive the benefit of any
statute now or hereafter in effect to the extent it is inconsistent with the
terms of this Lease with respect to, or which affords Lessee the right to make
repairs at the expense of Lessor or to terminate this Lease by reason of any
needed repairs.

      7.3 UTILITY INSTALLATIONS; TRADE FIXTURES; ALTERATIONS.

            (a) DEFINITIONS; CONSENT REQUIRED. The term "UTILITY INSTALLATIONS"
is used in this Lease to refer to all carpeting, window coverings, air lines,
power panels, electrical distribution, security, fire protection systems,
communication systems, lighting fixtures, heating, ventilating, and air
conditioning equipment, plumbing, and fencing in, on or about the Premises. The

ALTERATIONS AND/OR UTILITY INSTALLATIONS" are defined as Alterations and/or
Utility Installations made by Lessee that are not yet owned by Lessor as defined
in Paragraph 7.4(a). Lessee shall not make any Alterations or Utility
Installations in, on, under or about the Premises without Lessor's prior written
consent. Lessee may, however, make non-structural Utility Installations to the
interior of the Premises (excluding the roof), as long as they are not visible
from the outside, do not involve puncturing, relocating or removing the roof or
any existing walls, and the cumulative cost thereof during the term of this
Lease as extended does not exceed $25,000.

            (b) CONSENT. Any Alterations or Utility Installations that Lessee
shall desire to make and which require the consent of the Lessor shall be
presented to Lessor in written form with proposed detailed plans. All consents
given by Lessor, whether by virtue of Paragraph 7.3(a) or by subsequent specific
consent, shall be deemed conditioned upon: (i) Lessee's acquiring all applicable
permits required by governmental authorities, (ii) the furnishing of copies of
such permits together with a copy of the plans and specifications for the
Alteration or Utility Installation to Lessor prior to commencement of the work
thereon, and (iii) the compliance by Lessee with all conditions of said permits
in a prompt and expeditious manner. Any Alteration or Utility Installations by

obligation to do so) condition its consent to any requested Alteration or
Utility Installation that costs $10,000 or more upon Lessee's providing Lessor
with a lien and completion bond in an amount equal to one and one-half times the
estimated cost of such Alteration or Utility Installation and/or upon Lessee's
posting an additional Security Deposit with Lessor under Paragraph 36 hereof.

            (c) INDEMNIFICATION. Lessee shall pay, when due, all claims for

at or for use on the Premises, which claims are or may be secured by any
mechanics' or materialmen's lien against the Premises or any interest therein.
Lessee shall give Lessor not less than ten (10) days' notice prior to the
commencement of any work in, on or about the Premises, and Lessor shall have the
right to post notices of non-responsibility in or on the Premises as provided by
law. If Lessee shall, in good faith, contest the validity of any such lien,
claim or demand, then Lessee shall, at its sole expense defend and protect
itself, Lessor and the Premises against the same and shall pay and satisfy any
such adverse judgment that may be rendered thereon before the enforcement
thereof against the Lessor or the Premises. If Lessor shall require, Lessee
shall furnish to Lessor a surety bond satisfactory to Lessor in an

interest to do so.

      7.4 OWNERSHIP; REMOVAL; SURRENDER; AND RESTORATION.

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

            (b) REMOVAL. Unless otherwise agreed in writing, Lessor may require
that any or all Lessee Owned Alterations or Utility Installations be removed by
the expiration or earlier termination of this Lease, notwithstanding their
installation may have been consented to by Lessor. Lessor may require the
removal at any time of all or any part of any Lessee Owned Alterations or
Utility Installations made without the required consent of Lessor.

            (c) SURRENDER/RESTORATION. Lessee shall surrender the Premises by
the end of the last day of the Lease term or any earlier termination date, with
all of the improvements, parts and surfaces thereof clean and free of debris and
in good operating order, condition and state of repair, ordinary wear and tear
excepted. "Ordinary wear and tear" shall not include any damage or deterioration
that would have been prevented by good maintenance practice or by Lessee
performing all of its obligations under this Lease. Except as otherwise agreed
or specified in writing by Lessor, the Premises, as surrendered, shall include
the Utility Installations. The obligation of Lessee shall include the repair of
any damage occasioned by the installation, maintenance or removal of Lessee's
Trade Fixtures, furnishings, equipment, and Alterations and/or Utility
Installations, as well as the removal of any storage tanks installed by or for
Lessee, and the removal, replacement, or remediation of any soil, material or
ground water contaminated by Lessee, all as may then be required by Applicable
Law and/or good service practice. Lessee's Trade Fixtures shall remain the
property of Lessee and shall be removed by Lessee subject to its obligation to
repair and restore the Premises per this Lease.

8. INSURANCE; INDEMNITY.

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

      8.2 LIABILITY INSURANCE.

            (a) CARRIED BY LESSEE. Lessee shall obtain and keep in force during
the term of this Lease a Commercial General Liability policy of insurance
protecting Lessee and Lessor (as an additional insured) against claims for
bodily injury, personal injury and property damage based upon, involving or
arising out of the ownership, use, occupancy or maintenance of the Premises and
all areas appurtenant thereto. Such insurance shall be on an occurrence basis
providing single limit coverage in an amount not less than $1,000,000 per
occurrence with an "Additional Insured-Managers or Lessors of Premises"
Endorsement and contain the "Amendment of the Pollution Exclusion" for damage
caused by heat, smoke or fumes from a hostile fire. The policy shall not contain
any intra-insured exclusions as between insured persons or organizations, but
shall include coverage for liability assumed under this Lease as an "insured
contract" for the performance of Lessee's indemnity obligations under this
Lease. The limits of said insurance required by this Lease or as carried by
Lessee shall not, however, limit the liability of Lessee nor relieve Lessee of
any obligation hereunder. All insurance to be

IACONO as Lessor.

carried by Lessee shall be primary to and not contributory with any similar
insurance carried by Lessor, whose insurance shall be considered excess
insurance only.

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

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

            (a) BUILDING AND IMPROVEMENTS.. The Insuring Party shall obtain and
keep in force during the term of this Lease a policy or policies in the name of
Lessor with loss payable to Lessor and to the holders of any mortgages, deeds of
trust or ground leases on the Premises ("LENDER(s)"), insuring loss or damage to
the Premises. The amount of such insurance shall be equal to the full
replacement cost of the Premises, as the same shall exist from time to time or
the amount required by the Lenders, but in no event more than the commercially
reasonable and available insurance value thereof if, by reason of the unique
nature or age of the improvements involved, such latter amount is less than full
replacement cost. If Lessor is the Insuring Party, however, Lessee Owned
Alterations and Utility Installations shall be insured by Lessee under Paragraph
8.4 rather than by Lessor. If the coverage is available and commercially
appropriate, such policy or policies shall insure against all risks of direct
physical loss or damage (except the perils of flood and/or earthquake unless
required by a Lender), including coverage for any additional costs resulting
from debris removal and reasonable amounts of coverage for the enforcement of
any ordinance or law regulating the reconstruction or replacement of any
undamaged sections of the Premises required to be demolished or removed by
reason of the enforcement of any building, zoning, safety or land use laws as
the result of a covered cause of loss. Said policy or policies shall also
contain an agreed valuation provision in lieu of any coinsurance clause, waiver
of subrogation, and inflation guard protection causing an increase in the annual
property insurance coverage amount by a factor of not less than the adjusted
U.S. Department of Labor Consumer Price Index for All Urban Consumers for the
city nearest to where the Premises are located. If such insurance coverage has a
deductible clause, the deductible amount shall not exceed $1,000 per occurrence,
and Lessee shall be liable for such deductible amount in the event of an Insured
Loss, as defined in Paragraph 9.1(c).

            (b) RENTAL VALUE. The Insuring Party shall, in addition, obtain and
keep in force during the term of this Lease a policy or policies in the name of
Lessor, with loss payable to Lessor and Lendor(s), insuring the loss of the full
rental and other charges payable by Lessee to Lessor under this Lease for one
(1) year (including all real estate taxes, insurance costs, and any scheduled
rental increases). Said insurance shall provide that in the event the Lease is
terminated by reason of an insured loss, the period of 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 unless the item in question has become the property of Lessor
under the terms of this Lease. If Lessee is the Insuring Party, the policy
carried by Lessee under this Paragraph 8.3 shall insure Lessee Owned Alterations
and Utility Installations.

      8.4 LESSEE'S PROPERTY INSURANCE. Subject to the requirements of Paragraph
8.5, Lessee at its cost shall either by separate policy or, at Lessor's option,
by endorsement to a policy already carried, maintain insurance coverage on all
of Lessee's personal property, Lessee Owned Alterations and Utility
Installations in, on, or about the Premises similar in coverage to that carried
by the Insuring Party under Paragraph 8.3. Such insurance shall be full
replacement cost coverage

IACONO as Lessor.

with a deductible of not to exceed $1,000 per occurrence. The proceeds from any
such insurance shall be used by Lessee for the replacement of personal property
or the restoration of Lessee Owned Alterations and Utility Installations. Lessee
shall be the Insuring Party with respect to the insurance required by this
Paragraph 8.4 and shall provide Lessor with written evidence that such insurance
is in force.

      8.5 INSURANCE POLICIES. Insurance required hereunder shall be in companies
duly licensed to transact business in the state where the Premises are located,
and maintaining during the policy term a "General Policyholders Rating" of at
least B+, V, or such other rating as may be required by a Lender having a lien
on the Premises, as set forth in the most current issue of "Best's Insurance
Guide." Lessee shall not do or permit to be done anything which shall invalidate
the insurance policies referred to in this Paragraph 8. If Lessee is the
Insuring Party, Lessee shall cause to be delivered to Lessor certified copies of
policies of such insurance or certificates evidencing the existence and amounts
of such insurance with the insureds and loss payable clauses as required by this
Lease. No such policy shall be cancellable or subject to modification except
after thirty (30) days prior written notice to Lessor. Lessee shall at least
thirty (30) days prior to the expiration of such policies, furnish Lessor with
evidence of renewals or "insurance binders" evidencing renewal thereof, or
Lessor may order such insurance and charge the cost thereof to Lessee, which
amount shall be payable by Lessee to Lessor upon demand. If the Insuring Party
shall fail to procure and maintain the insurance required to be carried by the
Insuring Party under this Paragraph 8, the other Party may, but shall not be
required to, procure and maintain the same, but at Lessee's expense.

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

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

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

9. DAMAGE OR DESTRUCTION.

      9.1 DEFINITIONS.

            (a) "PREMISES PARTIAL DAMAGE" shall mean damage or destruction to
the improvements on the Premises, other than Lessee Owned Alterations and
Utility Installations, the repair cost of which damage or destruction is less
than 50% of


<PAGE>

ADDENDUM "A" to the contract (Standard Industrial/Commercial Single-Tenant Lease
- Net) dated June 26, 1995 covering the premises commonly known as 2130 Research
Drive, Livermore, CA 94550 between FORMFACTOR, INC., as Lessee and PAUL E.
IACONO as Lessor.

the then Replacement Cost of the Premises immediately prior to such damage or
destruction, excluding from such calculation the value of the land and Lessee
Owned Alterations and Utility Installations.

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

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

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

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

      9.2 PARTIAL DAMAGE -- INSURED LOSS. If a Premises Partial Damage that is
an Insured Loss occurs, then Lessor shall, at Lessor's expense, repair such
damage (but not Lessee's Trade Fixtures or Lessee Owned Alterations and Utility
Installations) as soon as reasonably possible and this Lease shall continue in
full force and effect; provided, however, that Lessee shall, at Lessor's
election, make the repair of any damage or destruction the total cost to repair
of which is $10,000 or less, and, in such event, Lessor shall make the insurance
proceeds available to Lessee on a reasonable basis for that purpose.
Notwithstanding the foregoing, if the required insurance was not in force or the
insurance proceeds are not sufficient to effect such repair, the Insuring Party
shall promptly contribute the shortage in proceeds (except as to the deductible
which is Lessee's responsibility) as and when required to complete said repairs.
In the event, however, the shortage in proceeds was due to the fact that, by
reason of the unique nature of the improvements, full replacement cost insurance
coverage was not commercially reasonable and available, Lessor shall have no
obligation to pay for the shortage in insurance proceeds or to fully restore the
unique aspects of the Premises unless Lessee provides Lessor with the funds to
cover same, or adequate assurance thereof, within ten (10) days following
receipt of written notice of such shortage and request therefor. If Lessor
receives said funds or adequate assurance thereof within said ten (10) day
period, the party responsible for making the repairs shall complete them as soon
as reasonably possible and this Lease shall remain in full force and effect. If
Lessor does not receive such funds or assurance within said period, Lessor may
nevertheless elect by written notice to Lessee within ten (10) days thereafter
to make such restoration and repair as is commercially reasonable with Lessor
paying any shortage in proceeds, in which case this Lease shall remain in full
force and effect. If in such case Lessor does not so elect, then this Lease
shall terminate sixty (60) days following the occurrence of the damage or
destruction. Unless otherwise agreed, Lessee shall in no event have any right to
reimbursement from Lessor for any funds contributed by Lessee to repair any such
damage or destruction. Premises Partial Damage due to flood or earthquake shall
be subject to Paragraph 9.3 rather than Paragraph 9.2, notwithstanding that
there may be some insurance coverage, but the net proceeds of any such insurance
shall be made available for the repairs if made by either Party.

      9.3 PARTIAL DAMAGE -- UNINSURED LOSS. If a Premises Partial Damage that is
not an Insured Loss occurs, unless caused by a negligent or willful act of
Lessee (in which event Lessee shall make the repairs at Lessee's expense and
this Lease shall continue in full force and effect, but subject to Lessor's
rights under Paragraph 13), Lessor may at Lessor's option, either: (i) repair
such damage as soon as reasonably possible at Lessor's expense, in which event
this Lease shall continue in full force and effect, or (ii) give written notice
to Lessee within thirty (30) days after receipt by Lessor of knowledge of the
occurrence of such damage of Lessor's desire to terminate this Lease as of the
date sixty (60) days following the giving of such notice. In the event Lessor
elects to give such notice of Lessor's intention to terminate this Lease, Lessee
shall have the right within ten (10) days after the receipt of such notice to
give written notice to Lessor of Lessee's commitment to pay for the repair of
such damage totally at Lessee's expense and without reimbursement from Lessor.
Lessee shall provide Lessor with the required funds or satisfactory assurance
thereof within thirty (30) days following Lessee's said commitment. In such
event this Lease shall continue in full force and effect, and Lessor shall

IACONO as Lessor.

proceed to make such repairs as soon as reasonably possible and the required
funds are available. If Lessee does not give such notice and provide the funds
or assurance thereof within the times specified above, this Lease shall
terminate as of the date specified in Lessor's notice of termination.

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

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

      9.6 ABATEMENT OF RENT; LESSEE'S REMEDIES.

            (a) In the event of damage described in Paragraph 9.2 (Partial
Damage -- Insured), whether or not Lessor or Lessee repairs or restores the
Premises, the Base Rent, Real Property Taxes, insurance premiums, and other
charges, if any, payable by Lessee hereunder for the period during which such
damage, its repair or the restoration continues (not to exceed the period for
which rental value insurance is required under Paragraph 8.3(b)), shall be
abated in proportion to the degree to which Lessee's use of the Premises is
impaired. Except for abatement of Base Rent, Real Property Taxes, insurance
premiums, and other charges, if any, as aforesaid, all other obligations of
Lessee hereunder shall be performed by Lessee, and Lessee shall have no claim
against Lessor for any damage suffered by reason of any such repair or
restoration.

            (b) If Lessor shall be obligated to repair or restore the Premises
under the provisions of this Paragraph 9 and shall not commence, in a
substantial and meaningful way, the repair or restoration of the Premises within
ninety (90) days after such obligation shall accrue, Lessee may, at any time
prior to the commencement of such repair or restoration, give written notice to
Lessor and to any Lenders of which Lessee has actual notice of Lessee's election
to terminate this Lease on a date not less than sixty (60) days following the
giving of such notice. If Lessee gives such notice to Lessor and such Lenders
and such repair or restoration is not commenced within thirty (30) days after
receipt of such notice, this Lease shall terminate as of the date specified in
said notice. If Lessor or a Lender commences the repair or restoration of the
Premises within thirty (30) days after receipt of such notice, this Lease shall
continue in full force and effect. "COMMENCE" as used in this Paragraph shall
mean either the unconditional authorization of the preparation of the required
plans, or the beginning of the actual work on the Premises, whichever first
occurs.

      9.7 HAZARDOUS SUBSTANCE CONDITIONS. If a Hazardous Substance Condition
occurs, unless Lessee is legally responsible therefor (in which case Lessee
shall make the investigation and remediation thereof required by Applicable Law
and this Lease shall continue in full force and effect, but subject to Lessor's
rights under Paragraph 13), Lessor may at Lessor's option either (i) investigate
and remediate such Hazardous Substance Condition, if required, as soon as
reasonably possible at Lessor's expense, in which event this Lease shall
continue in full force and effect, or (ii) if the estimated cost to investigate
and remediate such condition exceeds twelve (12) times the then monthly Base
Rent or $100,000, whichever is

IACONO as Lessor.

greater, give written notice to Lessee within thirty (30) days after receipt by
Lessor of knowledge of the occurrence of such Hazardous Substance Condition of
Lessor's desire to terminate this Lease as of the date sixty (60) days following
the giving of such notice. In the event Lessor elects to give such notice of
Lessor's intention to terminate this Lease, Lessee shall have the right within
ten (10) days after the receipt of such notice to give written notice to Lessor
of Lessee's commitment to pay for the investigation and remediation of such
Hazardous Substance Condition totally at Lessee's expense and without
reimbursement from Lessor except to the extent of an amount equal to twelve (12)
times the then monthly Base Rent or $100,000,whichever is greater. Lessee shall
provide Lessor with the funds required of Lessee or satisfactory assurance
thereof within thirty (30) days following Lessee's said commitment. In such
event this Lease shall continue in full force and effect, and Lessor shall
proceed to make such investigation and remediation as soon as reasonably
possible and the required funds are available. If Lessee does not give such
notice and provide the required funds or assurance thereof within the times
specified above, this Lease shall terminate as of the date specified in Lessor's
notice of termination. If a Hazardous Substance Condition occurs for which
Lessee is not legally responsible, there shall be abatement of Lessee's
obligations under this Lease to the same extent as provided in Paragraph 9.6(a)
for a period of not to exceed twelve (12) months.

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

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

10. REAL PROPERTY TAXES.

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

            (b) ADVANCE PAYMENT. In order to insure payment when due and before
any delinquency of any or all Real Property Taxes, Lessor reserves the right, at
Lessor's option, to estimate the current Real Property Taxes applicable to the
Premises, and to require such current year's Real Property Taxes to be paid in
advance to Lessor by Lessee, either: (i) in a lump sum amount equal to the
installment due, at least twenty (20) days prior to the applicable delinquency
date, 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 the Paragraph may, subject to proration as provided in
Paragraph 10.1(a), at the option of Lessor, be treated as an additional Security
Deposit under Paragraph 5.

      10.2 DEFINITION OF "REAL PROPERTY TAXES." As used herein, the term "REAL
PROPERTY TAXES" shall include any form of real estate tax or assessment,
general, special, ordinary or extraordinary, and any license fee, commercial
rental tax, improvement bond or bonds, levy or tax (other than inheritance,
personal, income or estate taxes) imposed upon the Premises

by any authority having the direct or indirect power to tax, including any city,
state or federal government, or any school, agricultural, sanitary, fire,
street, drainage or other improvement district thereof, levied against any legal
or equitable interest of Lessor in the Premises or in the real property of which
the Premises are a part. Lessor's right to rent or other income therefrom,
and/or Lessor's business of leasing the Premises. The term "REAL PROPERTY TAXES"
shall also include any tax, fee, levy, assessment or charge, or any increase
therein imposed by reason of events occurring, or changes in applicable law
taking effect, during the term of this Lease, including but not limited to a
change in the ownership of the Premises or in the improvements thereon, the
execution of this Lease, or any modification, amendment or transfer thereof, and
whether or not contemplated by the Premises.

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

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

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

12. ASSIGNMENT AND SUBLETTING.

      12.1 LESSOR'S CONSENT REQUIRED.

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

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

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

            (d) An assignment or subletting of Lessee's interest in this Lease
without Lessor's specific prior written consent shall, at Lessor's option, be a
Default curable after notice per Paragraph 13.1(c), or a noncurable Breach
without the necessity of any notice and grace period. If Lessor elects to treat
such unconsented to assignment or subletting as a noncurable Breach, Lessor
shall have the right to either: (i) terminate this Lease, or (ii) upon thirty
(30) days written notice ("LESSOR'S NOTICE"), increase the monthly Base Rent to
fair market rental value or one hundred ten percent (110%) of the


<PAGE>

ADDENDUM "A" to the contract (Standard Industrial/Commercial Single-Tenant Lease
- Net) dated June 26, 1995 covering the premises commonly known as 2130 Research
Drive, Livermore, CA 94550 between FORMFACTOR, INC., as Lessee and PAUL E.
IACONO as Lessor.

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

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

      12.2 TERMS AND CONDITIONS APPLICABLE TO ASSIGNMENT AND SUBLETTING.

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

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

            (c) The consent of Lessor to any assignment or subletting shall not
constitute a consent to any subsequent assignment or subletting by Lessee or to
any subsequent or successive assignment or subletting by the sublessee. However,
Lessor may consent to subsequent sublettings and assignments of the sublease or
any amendments or modifications thereto without notifying Lessee or anyone else
liable on the Lease or sublease and without obtaining their consent, and such
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 sublessee, without first exhausting Lessor's remedies
against any other person or entity responsible therefore 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 such other
or additional information and/or documentation as may be reasonable requested by
Lessor.

            (f) Any assignee of, or sublessee under, this Lease shall, by reason
of accepting such assignment or entering into such sublease, be deemed, for the
benefit of Lessor, to have assumed and agreed to conform and comply with each
and every term, covenant, condition and obligation herein to be observed or
performed by Lessee during the term of said assignment or sublease, other than
such obligations as are contrary to or inconsistent with provisions of an
assignment or sublease to which Lessor has specifically consented in writing.

ADDENDUM "A" to the contract (Standard Industrial/Commercial Single-Tenant Lease
- Net) dated June 26, 1995 covering the premises commonly known as 2130 Research
Drive, Livermore, CA 94550 between FORMFACTOR, INC., as Lessee and PAUL E.
IACONO as Lessor.

            (g) The occurrence of a transaction described in Paragraph 12.1(c)
shall give Lessor the right (but not the obligation) to require that the
Security Deposit be increased to an amount equal to six (6) times the then
monthly base Rent, and Lessor may make the actual receipt by Lessor 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 to the sublessee for any failure of
Lessee to perform and comply with any of Lessee's obligations to such sublessee
under such sublease. Lessee hereby irrevocably authorizes and directs any such
sublessee, upon receipt of a written notice from Lessor stating that a Breach
exists in the performance of Lessee's obligations under this Lease, to pay to
Lessor the rents and other charges due and to become due under the sublease.
Sublessee shall rely upon any statement and request from Lessor and shall pay
such rents and other charges to Lessor without any obligation or right to
inquire as to whether such Breach exists and notwithstanding any notice from or
claim from Lessee to the contrary. Lessee shall have no right or claim against
said sublessee, or, until the Breach has been cured, against Lessor, for any
such rents and other charges so paid by said sublessee to Lessor.

            (b) In the event of a Breach by Lessee in the performance of its
obligations under this Lease, Lessor, at its option and without any obligation
to do so, may require any sublessee to attorn to Lessor, in which event Lessor
shall undertake the obligations of the sublessor under such sublease from the
time of the exercise of said option to the expiration of such sublease;
provided, however, Lessor shall not be liable for any prepaid rents or security
deposit paid by such sublessee to such sublessor or for any other prior Defaults
or Breaches of such sublessor under such sublease.

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

            (d) No sublessee shall further assign or sublet all or any part of
the Premises without Lessor's prior written consent.

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

13. DEFAULT; BREACH; REMEDIES.

      13.1 DEFAULT; BREACH. Lessor and Lessee agree that if an attorney is
consulted by Lessor in connection with a Lessee Default or Breach (as
hereinafter defined), $350 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 in cure said Default. A "DEFAULT" is defined as a
failure by the Lessee to observe, comply with or perform any of the terms,
covenants, conditions or rules applicable to Lessee under this Lease. A "BREACH"
is defined as the occurrence of any one or more of the following Defaults, and,
where a grace period for cure after notice is

IACONO as Lessor.

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:

            (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) or (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.

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

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

            (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 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


<PAGE>

ADDENDUM "A" to the contract (Standard Industrial/Commercial Single-Tenant Lease
- Net) dated June 26, 1995 covering the premises commonly known as 2130 Research
Drive, Livermore, CA 94550 between FORMFACTOR, INC., as Lessee and PAUL E.
IACONO as Lessor.

such performance by Lessor shall be due and payable by Lessee to Lessor upon
invoice therefore. If any check given to Lessor by Lessee shall not be honored
by the bank upon which it is drawn, Lessor, at its option, may require all
future payments to be made under this Lease by Lessee to be made only by
cashier's check. In the event of a Breach of this Lease by Lessee, as defined in
Paragraph 13.1, with or without further notice or demand, and without limiting
Lessor in the exercise of any right or remedy which Lessor may have by reason of
such Breach, Lessor may:

            (a) Terminate Lessee's right to possession of the Premises by any
lawful means, in which case this Lease and the term hereof shall terminate and
Lessee shall immediately surrender possession of the Premises to Lessor. In such
event Lessor shall be entitled to recover from Lessee: (i) the worth at the time
of the award of the unpaid rent which had been earned at the time of
termination; (ii) the worth at the time of award of the amount by which the
unpaid rent which would have been earned after termination until the time of
award exceeds the amount of such rental loss that the Lessee proves could have
been reasonably avoided; (iii) the worth at the time of award of the amount by
which the unpaid rent for the balance of the term after the time of award
exceeds the amount of such rental loss that the Lessee proves could be
reasonably avoided; and (iv) any other amount necessary to compensate Lessor for
all the detriment proximately caused by the Lessee's failure to perform its
obligations under this Lease or which in the ordinary course of things would be
likely to result therefrom, including but not limited to the cost of recovering
possession of the Premises, expenses of reletting, including necessary
renovation and alteration of the Premises, reasonable attorneys' fees, and that
portion of the leasing commission paid by Lessor applicable to the unexpired
term of this Lease. The worth at the time of award of the amount referred to in
provision (iii) of the prior sentence shall be computed by discounting such
amount at the discount rate of the Federal Reserve Bank of San Francisco at the
time of award plus one percent (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 Lessor may reserve therein the right to recover all or
any part thereof in a separate suit for such rent and/or damages. If a notice
and grace period required under subparagraphs 13.1(b), (c) or (d) was not
previously given, a notice to pay rent or quit, or to perform or quit, as the
case may be, given to Lessee under any statute authorizing the forfeiture of
leases for unlawful detainer shall also constitute the applicable notice for
grace period purposes required by subparagraphs 13.1(b), (c) or (d). In such
case, the applicable grace period under subparagraphs 13.1(b), (c) or (d) and
under the unlawful detainer statute shall run concurrently after the one such
statutory notice, and the failure of Lessee to cure the Default within the
greater of the two such grace periods shall constitute both an unlawful detainer
and a Breach of this Lease entitling Lessor to the remedies provided for in this
Lease and/or by said statute.

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

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

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

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

ADDENDUM "A" to the contract (Standard Industrial/Commercial Single-Tenant Lease
- Net) dated June 26, 1995 covering the premises commonly known as 2130 Research
Drive, Livermore, CA 94550 between FORMFACTOR, INC., as Lessee and PAUL E.
IACONO as Lessor.

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 title or
possession, whichever first occurs. If more than ten percent (10%) of the floor
area of the Premises, or more than twenty-five percent (25%) of the land area
not occupied by any building, is taken by condemnation, Lessee may, at Lessee's
option, to be exercised in writing within ten (10) days after Lessor shall have
given Lessee written notice of such taking (or in the absence of such notice,
within ten (10) days after the condemning authority shall have taken possession)
terminate this Lease as of the date the condemning authority takes such
possession. If Lessee does not terminate this Lease in accordance with the
foregoing, this Lease shall remain in full force and effect as to the portion of
the Premises remaining, except that the Base Rent shall be reduced in the same
proportion as the rentable floor area of the Premises taken bears to the total
rentable floor area of the building located on the Premises. No reduction of
Base Rent shall occur if the only portion of the Premises taken is land on which
there is no building. Any award for the taking of all or any part of the
Premises under the power of eminent domain or any payment made under threat of
the exercise of such power shall be the property of Lessor, whether such award
shall be made as compensation for diminution in value of the leasehold or for
the taking of the fee, or as severance damages; provided, however, that Lessee
shall be entitled to any compensation separately awarded to Lessee for Lessee's
relocation expenses and/or loss of Lessee's Trade Fixtures. In the event that
this Lease is not terminated by reason of such condemnation, Lessor shall to the
extent of its net severance damages received, over and above the legal and other
expenses incurred by Lessor in the condemnation matter, repair any damage to the
Premises caused by such condemnation, except to the extent that Lessee has been
reimbursed therefore by the condemning authority. Lessee shall be responsible
for the payment of any amount in excess of such net severance damages required
to complete such repair.

15. BROKER'S FEE.

      15.1 The Broker's named in Paragraph 1.10 are the procuring causes of this
Lease.

      15.2 Upon execution of this Lease by both Parties, Lessor shall pay to
said Brokers jointly, or in such separate shares as they may mutually designate
in writing, a fee as set forth in a separate written agreement between Lessor
and said Brokers

Brokers, the sum of $_15,000.00_ per agreement) for brokerage services rendered

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

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

      15.5 Lessee and Lessor each represent and warrant to the other that it has

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 and approve all agency
relationships, including any dual agencies, indicated in Paragraph 1.10.

16. TENANCY STATEMENT.

written notice from the other Party (the "REQUESTING PARTY") execute,
acknowledge and deliver to the Requesting party a statement in writing in form
similar to the then most current "TENANCY STATEMENT" form published by the
American Industrial Real Estate Association, plus such additional information,
confirmation and/or statements as may be reasonably requested by the Requesting
Party.

      16.2 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 hereinafter defined.

- Net) dated June 26, 1995 covering the premises commonly known as 2130 Research
Drive, Livermore, CA 94550 between FORMFACTOR, INC., as Lessee and PAUL E.
IACONO as Lessor.

18. SEVERABILITY. The invalidity of any provision of this Lease, as determined
by a court of competent jurisdiction, shall in no way affect the validity of any
other provision hereof.

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

20. TIME OF ESSENCE. Time is of the essence with respect to the performance of
all obligations to be performed or observed by the Parties under this Lease.

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

22. NO PRIOR OR OTHER AGREEMENTS; BROKER DISCLAIMER. This Lease contains all
agreements between the Parties with respect to any matter mentioned herein, and
no other prior or contemporaneous agreement or understanding shall be effective.
Lessor and Lessee each represents and warrants to the Brokers that it has made,
and is relying solely upon, its own investigation as to the nature, quality,
character and financial responsibility of the other Party to this Lease and as
to the nature, quality and character of the Premises. Brokers have no
responsibility with respect thereto or with respect to any default or breach
hereof by either Party.

23. NOTICES.

      23.1 All notices required or permitted by this Lease shall be in writing
and may be delivered in person (by hand or by messenger or courier service) or
may be sent by regular, 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
card, or if no delivery date is shown, the postmark thereon. If sent by regular
mail the notice shall be deemed given forty-eight (48) hours after the same is
addressed as required herein and mailed with postage prepaid. Notices delivered
by United States Express Mail or overnight courier that guarantees next day
delivery shall be deemed given twenty-four (24) hours after delivery of the same
to the United States 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 requiring such consent. Regardless of Lessor's
knowledge of a Default or Breach at the time of accepting rent, the acceptance
of rent by Lessor shall not be a waiver of any preceding Default or Breach by
Lessee of any provision hereof, other than the failure of Lessee to pay the
particular rent so accepted. Any payment given Lessor by Lessee may be accepted
by Lessor on account of moneys or damages due Lessor, notwithstanding any
qualifying statements or conditions made by Lessee in connection therewith,
which such statements and/or conditions shall be of no force or effect
whatsoever unless specifically agreed to in writing by Lessor at or before the
time of deposit of such payment.

IACONO as Lessor.

25. RECORDING. Either Lessor or Lessee shall, upon request of the other,

26. NO RIGHT TO HOLDOVER. Lessee has no right to retain possession of the
Premises or any part thereof beyond the expiration or earlier termination of
this Lease.

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

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

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

30. SUBORDINATION; ATTORNMENT; NON-DISTURBANCE.

      30.1 SUBORDINATION. This Lease and any Option granted hereby shall be
subject and subordinate to any ground lease, mortgage, deed of trust, or other
hypothecation or security device (collectively, "SECURITY DEVICE"), now or
hereafter placed by Lessor upon the real property of which the Premises are a
part, to any and all advances made on the security thereof, and to all renewals,
modifications, consolidations, replacements and extensions thereof. Lessee
agrees that the Lenders holding any such Security Device shall have no duty,
liability or obligation to perform any of the obligations of Lessor under this
Lease, but in the event of Lessor's default with respect to such obligation,
Lessee will given 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 or Broker brings an action or proceeding to
enforce the terms hereof or declare rights hereunder, the Prevailing Party (as
hereafter defined) or Broker in any such proceeding, action or appeal thereon,
shall be entitled to reasonable attorney's fees. Such fees may be awarded in the
same suit or recovered in a separate suit, whether or not such action or
proceeding is pursued to decision or judgment. The term "PREVAILING PARTY,"
shall include, without limitation, a Party or Broker who substantially obtains
or defeats the relief sought, as the case may be, whether by


<PAGE>

ADDENDUM "A" to the contract (Standard Industrial/Commercial Single-Tenant Lease
- Net) dated June 26, 1995 covering the premises commonly known as 2130 Research
Drive, Livermore, CA 94550 between FORMFACTOR, INC., as Lessee and PAUL E.
IACONO as Lessor.

compromise, settlement, judgment, or the abandonment by the other party or
Broker 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. Lessee shall not place any sign upon the Premises, except that Lessee
may, with Lessor's prior written consent, install (but not on the roof) such
signs as are reasonably required to advertise Lessee's own business. The
installation of any sign on the Premises by or for Lessee shall be subject to
the provisions of Paragraph 7 (Maintenance, Repairs, Utility Installations,
Trade Fixtures and Alterations). Unless otherwise expressly agreed herein,
Lessor reserves all rights to the use of the roof and the right to install, and
all revenues from the installation of, such advertising signs on the Premises,
including the roof, as do not unreasonably interfere with the conduct of
Lessee's business.

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

36. CONSENTS.

      (a) Except for Paragraph 33 hereof (Auctions) or as otherwise provided
herein, wherever in this Lease the consent of a Party is required to an act by
or for the other Party, such consent shall not be unreasonably withheld or
delayed. Lessor's actual reasonable costs and expenses (including but not
limited to architects', attorneys', engineers' or other consultants fees)
incurred in the consideration of, or response to, a request by Lessee for any
Lessor consent pertaining to this Lease or the Premises, including but not
limited to consents to an assignment, a subletting or the presence or use of a
Hazardous Substance, practice or storage tank, shall be paid by Lessee to Lessor
upon receipt of an invoice and supporting documentation therefore. 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 acknowledgement that no Default
or Breach by Lessee of this Lease exists, nor shall such consent be deemed a
waiver of any then existing Default or Breach, except as may be otherwise
specifically stated in writing by Lessor at the time of such consent.

      (b) All conditions to Lessor's consent authorized by this Lease are
acknowledged by Lessee as being reasonable. The failure to specify herein any
particular condition to Lessor's consent shall not preclude the imposition by
Lessor at the

IACONO as Lessor.

time of consent of such further or other conditions as are then reasonable with
reference to the particular matter for which consent is being given.

37. GUARANTOR.

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

      37.2 It shall constitute a Default of the Lessee under this Lease if any
such Guarantor fails or refuses, upon reasonable request by Lessor to give (a)
evidence of the due execution of the guaranty called for by this Lease,
including the authority of the Guarantor (and of the party signing on
Guarantor's behalf) to obligate such Guarantor on said guaranty, and including
in the case of a corporate Guarantor, a certified copy of a resolution of its
board of directors authorizing the making of such guaranty, together with a
certificate of incumbency showing the 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 of all of the covenants, conditions and provisions on Lessee's
part to be observed and performed under this Lease, Lessee shall have quiet
possession of the Premises for the entire term hereof subject to all of the
provisions of this Lease.

39. OPTIONS.

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

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

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

      39.4 EFFECT OF DEFAULT ON OPTIONS.

            (a) Lessee shall have no right to exercise an Option,
notwithstanding any provision in the grant of Option to the contrary: (i) during
the period commencing with the giving of any notice of Default under Paragraph
13.1 and continuing until the noticed Default is cured, or (ii) during the
period of time any monetary obligation due Lessor from Lessee is unpaid (without
regard to whether notice thereof is given Lessee), or (iii) during the time
Lessee is in Breach of this Lease, or (iv) in the event that Lessor has given to
Lessee three (3) or more notices of Default under Paragraph 13.1, whether or not
the Defaults are cured, during the twelve (12) month period immediately
preceding the exercise of the Option.

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


<PAGE>

ADDENDUM "A" to the contract (Standard Industrial/Commercial Single-Tenant Lease
- Net) dated June 26, 1995 covering the premises commonly known as 2130 Research
Drive, Livermore, CA 94550 between FORMFACTOR, INC., as Lessee and PAUL E.
IACONO as Lessor.

            (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 tenants of such other buildings and their
invitees, and that Lessee will pay its fair share of common expenses incurred in
connection therewith.

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

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

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

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

typewritten or handwritten provisions shall be controlled by the typewritten or
handwritten provisions.

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.
