This Security Agreement is entered into as of the above date between the above-

1.   DEFINITIONS OF OBLIGATIONS AND COLLATERAL; GRANT OF SECURITY INTEREST.

     1.1  Obligations. The term "Obligations" as used in this Agreement shall
mean and include each and all of the following: the obligation to pay and
perform when due all indebtedness, liabilities, obligations, guarantees,
covenants, agreements, warranties and representations of Debtor to Silicon,
whether heretofore, now or hereafter existing, owing or arising; whether
primary, secondary, direct, absolute, contingent, fixed, secured or unsecured;
joint or several, monetary or non-monetary; and whether created pursuant to, or
caused by Debtor's breach of, this Agreement, or any other present or future
agreement or instrument, or created by operation of law or otherwise. The
Obligations include without limitation the obligations of Debtor under that
certain Continuing Guaranty in favor of Silicon with respect to the indebtedness
of NetPlex Systems, Inc., and all extensions and renewals thereof.
   ---------------------
     1.2  Collateral. To secure the payment and performance of all of the
Obligations when due, Debtor hereby grants to Silicon a security interest in all
of Debtor's interest in the following, whether now owned or hereafter acquired,
and wherever located (collectively, the "Collateral"): All Inventory, Equipment,
Receivables, and General Intangibles, including, without limitation, all of
Debtor's Deposit Accounts, all money, all collateral in which Silicon is granted
a security interest pursuant to any other present or future agreement, all
property now or at any time in the future in Silicon's possession, and all
proceeds (including proceeds of any insurance policies, proceeds of proceeds and
claims against third parties), all products of the foregoing, and all books and
records related to any of the foregoing.

2.   REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE DEBTOR.

     In order to induce Silicon to enter into this Agreement, Debtor represents
and warrants to Silicon as follows, and Debtor covenants that the following
representations will continue to be true, and that Debtor will at all times
comply with all of the following covenants:

     2.1  Corporate Existence and Authority. Debtor, if a corporation, is and
will continue to be, duly organized, validly existing and in good standing under
the laws of the jurisdiction of its incorporation. Debtor is and will continue
to be qualified and licensed to do business in all jurisdictions in which any
failure to do so would have a material adverse effect on Debtor. The execution,
delivery and performance by Debtor of this Agreement, and all other documents
contemplated hereby (i) have been duly and validly authorized, (ii) are
enforceable against Debtor in accordance with their terms (except as enforcement
may be limited by equitable principles and by bankruptcy, insolvency,
reorganization, moratorium or similar laws relating to creditors' rights
generally), (iii) do not violate Debtor's articles or certificate of
incorporation, or Debtor's by-laws, or any law or any material agreement or
instrument which is binding upon Debtor or its property, and (iv) do not
constitute grounds for acceleration of any material indebtedness or obligation
under any material agreement or instrument which is binding upon Debtor or its
property.

     2.2  Name; Trade Names and Styles. The name of Debtor set forth in the
heading to this Agreement is its correct name. Listed on the Schedule are all
prior names of Debtor and all of Debtor's present and (to the best of its
knowledge) prior trade names. Debtor shall give Silicon 30 days' prior written
notice before changing its name or doing business under any other name. Debtor
has complied, and will in the future comply, with all laws relating to the
conduct of business under a fictitious business name.

     2.3  Place of Business; Location of Collateral. The address set forth in
the heading to this Agreement is Debtor's chief executive office. In addition,
Debtor has places of business and Collateral is located only at the locations
set forth on the Schedule. Debtor will give Silicon at least 30 days prior
written notice before opening any additional place of business, changing its
chief executive office, or

                                      -1-

--------------------------------------------------------------------------------

moving any of the Collateral to a location other than Debtor's Address or one of
the locations set forth on the Schedule.

     2.4  Title to Collateral; Permitted Liens. Debtor is now, and will at all
times in the future be, the sole owner of all the Collateral, except for items
of Equipment which are leased by Debtor. The Collateral now is and will remain
free and clear of any and all liens, charges, security interests, encumbrances
and adverse claims, except for Permitted Liens. Silicon now has, and will
continue to have, a first-priority perfected and enforceable security interest
in all of the Collateral, subject only to the Permitted Liens, and Debtor will
at all times defend Silicon and the Collateral against all claims of others.
Whenever any Collateral is located upon premises in which any third party has an
interest (whether as owner, mortgagee, beneficiary under a deed of trust, lien
or otherwise), Debtor shall, whenever requested by Silicon, use its commercially
reasonable efforts to cause such third party to execute and deliver to Silicon,
in form acceptable to Silicon, such waivers and subordinations as Silicon shall
specify, so as to ensure that Silicon's rights in the Collateral are, and will
continue to be, superior to the rights of any such third party. Debtor will keep
in full force and effect, and will comply with all the terms of, any lease of
real property where any of the Collateral now or in the future may be located,
except to the extent Debtor relocates its chief executive office or moves any
Collateral in accordance with Section 2.3 hereof.

     2.5  Maintenance of Collateral. Debtor will maintain the Collateral in good
working condition, ordinary wear and tear excepted, and Debtor will not use the
Collateral for any unlawful purpose. Debtor will immediately advise Silicon in
writing of any material loss or damage to the Collateral.

     2.6  Books and Records. Debtor has maintained and will maintain at Debtor's
Address complete and accurate books and records, comprising an accounting system
in accordance with generally accepted accounting principles.

     2.7  Financial Condition, Statements and Reports. All financial statements
now or in the future delivered to Silicon have been, and will be, prepared in
conformity with generally accepted accounting principles and now and in the
future will completely and fairly reflect the financial condition of Debtor, at
the times and for the periods therein stated. Except as otherwise previously
disclosed to Silicon in writing, between the last date covered by any such
statement provided to Silicon and the date hereof, there has been no material
adverse change in the financial condition or business of Debtor. Debtor is now
and will continue to be solvent.

     2.8  Tax Returns and Payments; Pension Contributions. Debtor has timely
filed, and will timely file, all tax returns and reports required by applicable
law, and Debtor has timely paid, and will timely pay, all applicable taxes,
assessments, deposits and contributions now or in the future owed by Debtor.
Debtor may, however, defer payment of any contested taxes, provided that Debtor
(i) in good faith contests Debtor's obligation to pay the taxes by appropriate
proceedings promptly and diligently instituted and conducted, (ii) notifies
Silicon in writing of the commencement of, and any material development in, the
proceedings, and (iii) posts bonds or takes any other steps required to keep the
contested taxes from becoming a lien upon any of the Collateral. Debtor is
unaware of any claims or adjustments proposed for any of Debtor's prior tax
years which could result in additional taxes becoming due and payable by Debtor.
Debtor has paid, and shall continue to pay all amounts necessary to fund all
present and future pension, profit sharing and deferred compensation plans in
accordance with their terms, and Debtor has not and will not withdraw from
participation in, permit partial or complete termination of, or permit the
occurrence of any other event with respect to, any such plan which could result
in any liability of Debtor, including any liability to the Pension Benefit
Guaranty Corporation or any other governmental agency. Debtor shall, at all
times, utilize the services of an outside payroll service providing for the
automatic deposit of all payroll taxes payable by Debtor (provided, however, the
foregoing sentence shall not be applicable to Contractors Resources, Inc.).

     2.9  Compliance with Law. Debtor has complied, and will comply, in all
material respects, with all provisions of all applicable laws and regulations,
including, but not limited to, those relating to Debtor's ownership of real or
personal property, the conduct and licensing of Debtor's business, and all
environmental matters.

     2.10 Litigation. Except as disclosed in the Schedule, there is no claim,
suit, litigation, proceeding or investigation pending or (to best of Debtor's
knowledge) threatened by or against or affecting Debtor in any court or before
any governmental agency (or any basis therefor known to Debtor) which may
result, either separately or in the aggregate, in any material adverse change in
the financial condition or business of Debtor, or in any material impairment in
the ability of Debtor to carry on its business in substantially the same manner
as it is now being conducted. Debtor will promptly inform Silicon in writing of
any claim, proceeding, litigation or investigation in the future threatened or
instituted by or against Debtor involving any single claim of $50,000 or more,
or involving $100,000 or more in the aggregate.

3.   DUTIES OF THE DEBTOR.

     3.1  Insurance. Debtor shall, at all times, insure all of the tangible
personal property Collateral and carry such other business insurance, with
insurers reasonably acceptable to Silicon, in such form and amounts as Silicon
may reasonably require, and Debtor shall provide evidence of such insurance to
Silicon, so that Silicon is satisfied that such insurance is, at all times, in
full force and effect. All such insurance policies shall name Silicon as an
additional

                                      -2-

loss payee, and shall contain a lenders loss payee endorsement in form
reasonably acceptable to Silicon and Debtor shall provide evidence of such
endorsement to Silicon as soon as possible after the date hereof but in no event
later than 30 days after the date hereof. Upon receipt of the proceeds of any
such insurance, Silicon shall apply such proceeds in reduction of the
Obligations as Silicon shall determine in its sole discretion, except that,
provided no Default or Event of Default has occurred and is continuing, Silicon
shall release to Debtor insurance proceeds with respect to Equipment totaling
less than $100,000, which shall be utilized by Debtor for the replacement of the
Equipment with respect to which the insurance proceeds were paid. Silicon may
require reasonable assurance that the insurance proceeds so released will be so
used. If Debtor fails to provide or pay for any insurance, Silicon may, but is
not obligated to, obtain the same at Debtor's expense. Debtor shall promptly
deliver to Silicon copies of all reports made to insurance companies.

     3.2  Reports. Debtor, at its expense, shall provide Silicon with the
written reports set forth in the Schedule, and such other written reports with
respect to Debtor (including budgets, sales projections, operating plans and
other financial documentation), as Silicon shall from time to time reasonably
specify.

     3.3  Access to Collateral, Books and Records. At reasonable times, and on
one business day's notice, Silicon, or its agents, shall have the right to
inspect the Collateral, and the right to audit and copy Debtor's books and
records. Silicon shall take reasonable steps to keep confidential all
information obtained in any such inspection or audit, but Silicon shall have the
right to disclose any such information to its auditors, regulatory agencies, and
attorneys, and pursuant to any subpoena or other legal process.

     3.4  Negative Covenants. Except as may be permitted in the Schedule, Debtor
shall not, without Silicon's prior written consent, do any of the following: (i)
merge or consolidate with another corporation or entity; (ii) acquire any
assets, except in the ordinary course of business; (iii) enter into any other
transaction outside the ordinary course of business; (iv) sell or transfer any
Collateral, except that, provided no Default or Event of Default has occurred
and is continuing, Debtor may (a) sell finished Inventory in the ordinary course
of Debtor's business, and (b) sell Equipment in the ordinary course of business,
in good-faith arm's length transactions and (c) sell or transfer other
Collateral with a value of less than $50,000 (with an aggregate amount of such
sales or transfers of other Collateral during the term of this Agreement not to
exceed $100,000); (v) store any Inventory or other Collateral with any
warehouseman or other third party; (vi) sell any Inventory on a sale-or-return,
guaranteed sale, consignment, or other contingent basis; (vii) make any loans of
any money or other assets; (viii) incur any debts, outside the ordinary course
of business, which would have a material, adverse effect on Debtor or on the
prospect of repayment of the Obligations; (ix) guarantee or otherwise become
liable with respect to the obligations of another party or entity; (x) pay or
declare any dividends on Debtor's stock (except for dividends payable solely in
stock of Debtor) provided this subclause (x) shall not apply to The NetPlex
Group, Inc.; (xi) redeem, retire, purchase or otherwise acquire, directly or
indirectly, any of Debtor's stock; (xii) make any change in Debtor's capital
structure which would have a material adverse effect on Debtor or on the
prospect of repayment of the Obligations; or (xiii) dissolve or elect to
dissolve; or (xiv) agree to do any of the foregoing.

     3.5  Litigation Cooperation. Should any third-party suit or proceeding be
instituted by or against Silicon with respect to any Collateral or in any manner
relating to Debtor, Debtor shall, without expense to Silicon, make available
Debtor and its officers, employees and agents, and Debtor's books and records,
without charge, to the extent that Silicon may deem them reasonably necessary in
order to prosecute or defend any such suit or proceeding.

     3.6  Notification of Changes. Debtor will promptly notify Silicon in
writing of any change in its officers or directors, the opening of any new bank
account or other deposit account, and any material adverse change in the
business or financial affairs of Debtor.

     3.7  Further Assurances. Debtor agrees, at its expense, on request by
Silicon, to execute all documents and take all actions, as Silicon may deem
reasonably necessary or useful in order to perfect and maintain Silicon's
perfected security interest in the Collateral, and in order to fully consummate
the transactions contemplated by this Agreement.

     3.8  Indemnity. Debtor hereby agrees to indemnify Silicon and hold Silicon
harmless from and against any and all claims, debts, liabilities, demands,
obligations, actions, causes of action, penalties, costs and expenses (including
attorneys' fees), of every nature, character and description, which Silicon may
sustain or incur based upon or arising out of any of the Obligations, any actual
or alleged failure to collect and pay over any withholding or other tax relating
to Debtor or its employees, any relationship or agreement between Silicon and
Debtor, any actual or alleged failure of Silicon to comply with any writ of
attachment or other legal process relating to Debtor or any of its property, or
any other matter, cause or thing whatsoever occurred, done, omitted or suffered
to be done by Silicon relating to Debtor or the Obligations (except any such
amounts sustained or incurred as the result of the gross negligence or willful
misconduct of Silicon or any of its directors, officers, employees, agents,
attorneys, or any other person affiliated with or representing Silicon).
Notwithstanding any provision in this Agreement to the contrary, the indemnity
agreement set forth in this Section shall survive any termination of this
Agreement and shall for all purposes continue in full force and effect.

4.   TERM.  This Agreement shall continue in effect until all of the Obligations
have been paid and performed in full

                                      -3-

and all agreements between Silicon and Debtor have been terminated. Provided no
Event of Default has occurred, if a sale of Contractors Resources, Inc. occurs
(on terms satisfactory to Silicon in its good-faith business judgment), and the
net proceeds of such sale go to The NetPlex Group, Inc., this Agreement will
terminate with respect to Contractors Resources, Inc. (without requirement of
prepayment thereby) in accordance with the terms hereof.

5.   EVENTS OF DEFAULT AND REMEDIES.

     5.1  Events of Default. The occurrence of any of the following events shall
constitute an "Event of Default" under this Agreement, and Debtor shall give
Silicon immediate written notice thereof: (a) Any warranty, representation,
statement, report or certificate made or delivered to Silicon by Debtor or any
of Debtor's officers, employees or agents, now or in the future, shall be untrue
or misleading in a material respect; or (b) Debtor shall fail to pay when due
any monetary Obligation; or (c) Debtor shall fail to perform any non-monetary

obligation secured by a Permitted Lien, which is not cured within any applicable
cure period or waived in writing by the holder of the Permitted Lien; or (g)
Debtor breaches any material contract or obligation which remains uncured beyond
any applicable cure periods, which has or may reasonably be expected to have a
material adverse effect on Debtor's business or financial condition; or (h)

or appointment of a receiver, trustee or custodian, for all or any part of the
property of, assignment for the benefit of creditors by, or the commencement of
any proceeding by Debtor under any reorganization, bankruptcy, insolvency,
arrangement, readjustment of debt, dissolution or liquidation law or statute of
any jurisdiction, now or in the future in effect; or (i) the commencement of any
proceeding against Debtor under any reorganization, bankruptcy, insolvency,
arrangement, readjustment of debt, dissolution or liquidation law or statute of
any jurisdiction, now or in the future in effect, which is not cured by the

a change in the record or beneficial ownership of an aggregate of more than 20%

subclause (j) shall not be applicable to The NetPlex Group, Inc. nor to
Contractors Resources, Inc.) or (k) Debtor shall generally not pay its debts as
they become due, or Debtor shall conceal, remove or transfer any part of its
property, with intent to hinder, delay or defraud its creditors, or make or
suffer any transfer of any of its property which may be fraudulent under any
bankruptcy, fraudulent conveyance or similar law; or (l) there shall be a
material adverse change in Debtor's business or financial condition (provided,
however, this subclause (l) shall not be applicable to Contractors Resources,
Inc.).

     5.2  Remedies. Upon the occurrence and during the continuance of any Event
of Default, and at any time thereafter, Silicon, at its option, and without
notice or demand of any kind (all of which are hereby expressly waived by
Debtor), may do any one or more of the following: (a) Accelerate and declare all
or any part of the Obligations to be immediately due, payable, and performable,
notwithstanding any deferred or installment payments allowed by any instrument
evidencing or relating to any Obligation; (b) Take possession of any or all of
the Collateral wherever it may be found, and for that purpose Debtor hereby
authorizes Silicon without judicial process to enter onto any of Debtor's
premises without interference to search for, take possession of, keep, store, or
remove any of the Collateral, and remain on the premises or cause a custodian to
remain on the premises in exclusive control thereof, without charge for so long
as Silicon deems it reasonably necessary in order to complete the enforcement of
its rights under this Agreement or any other agreement; provided, however, that
should Silicon seek to take possession of any of the Collateral by Court
process, Debtor hereby irrevocably waives: (i) any bond and any surety or
security relating thereto required by any statute, court rule or otherwise as an
incident to such possession; (ii) any demand for possession prior to the
commencement of any suit or action to recover possession thereof; and (iii) any
requirement that Silicon retain possession of, and not dispose of, any such

otherwise dispose of any of the Collateral, in its condition at the time Silicon
obtains possession of it or after further manufacturing, processing or repair,
at one or more public and/or private sales, in lots or in bulk, for cash,
exchange or other property, or on credit, and to adjourn any such sale from time
to time without notice other than oral

--------------------------------------------------------------------------------

announcement at the time scheduled for sale. Silicon shall have the right to
conduct such disposition on Debtor's premises without charge, for such time or
times as Silicon deems reasonable, or on Silicon's premises, or elsewhere and
the Collateral need not be located at the place of disposition. Silicon may
directly or through any affiliated company purchase or lease any Collateral at
any such public disposition, and if permissible under applicable law, at any
private disposition. Any sale or other disposition of Collateral shall not
relieve Debtor of any liability Debtor may have if any Collateral is defective
as to title or physical condition or otherwise at the time of sale; (f) Demand
payment of, and collect any Receivables and General Intangibles comprising
Collateral and, in connection therewith, Debtor irrevocably authorizes Silicon
to endorse or sign Debtor's name on all collections, receipts, instruments and
other documents, to take possession of and open mail addressed to Debtor and
remove therefrom payments made with respect to any item of the Collateral or
proceeds thereof, and, in Silicon's sole discretion, to grant extensions of time
to pay, compromise claims and settle Receivables, General Intangibles and the
like for less than face value; and (h) Demand and receive possession of any of
Debtor's federal and state income tax returns and the books and records utilized
in the preparation thereof or referring thereto. All reasonable attorneys' fees,
expenses, costs, liabilities and obligations incurred by Silicon with respect to
the foregoing shall be added to and become part of the Obligations, shall be due
on demand, and shall bear interest at a rate equal to the highest interest rate
applicable to any of the Obligations.

     5.3  Standards for Determining Commercial Reasonableness. Debtor and
Silicon agree that a sale or other disposition (collectively, "sale") of any
Collateral which complies with the following standards will conclusively be
deemed to be commercially reasonable: (i) Notice of the sale is given to Debtor
at least seven days prior to the sale, and, in the case of a public sale, notice
of the sale is published at least seven days before the sale in a newspaper of
general circulation in the county where the sale is to be conducted; (ii) Notice
of the sale describes the collateral in general, non-specific terms; (iii) The
sale is conducted at a place designated by Silicon, with or without the
Collateral being present; (iv) The sale commences at any time between 8:00 a.m.
and 6:00 p.m; (v) Payment of the purchase price in cash or by cashier's check or
wire transfer is required; (vi) With respect to any sale of any of the
Collateral, Silicon may (but is not obligated to) direct any prospective
purchaser to ascertain directly from Debtor any and all information concerning
the same. Silicon shall be free to employ other methods of noticing and selling
the Collateral, in its discretion, if they are commercially reasonable.

     5.4  Power of Attorney. Upon the occurrence and during the continuance of
any Event of Default, without limiting Silicon's other rights and remedies,
Debtor grants to Silicon an irrevocable power of attorney coupled with an
interest, authorizing and permitting Silicon (acting through any of its
employees, attorneys or agents) at any time, at its option, but without
obligation, with or without notice to Debtor, and at Debtor's expense, to do any
or all of the following, in Debtor's name or otherwise, but Silicon agrees to
exercise the following powers in a commercially reasonable manner: (a) Execute
on behalf of Debtor any documents that Silicon may, in its sole discretion, deem
advisable in order to perfect and maintain Silicon's security interest in the
Collateral, or in order to exercise a right of Debtor or Silicon, or in order to
fully consummate all the transactions contemplated under this Agreement, and all
other present and future agreements; (b) Execute on behalf of Debtor any
document exercising, transferring or assigning any option to purchase, sell or
otherwise dispose of or to lease (as lessor or lessee) any real or personal
property which is part of Silicon's Collateral or in which Silicon has an
interest; (c) Execute on behalf of Debtor, any invoices relating to any
Receivable, any draft against any Account Debtor and any notice to any Account
Debtor, any proof of claim in bankruptcy, any Notice of Lien, claim of
mechanic's, materialman's or other lien, or assignment or satisfaction of
mechanic's, materialman's or other lien; (d) Take control in any manner of any
cash or non-cash items of payment or proceeds of Collateral; endorse the name of
Debtor upon any instruments, or documents, evidence of payment or Collateral
that may come into Silicon's possession; (e) Endorse all checks and other forms
of remittances received by Silicon; (f) Pay, contest or settle any lien, charge,
encumbrance, security interest and adverse claim in or to any of the Collateral,
or any judgment based thereon, or otherwise take any action to terminate or
discharge the same; (g) Grant extensions of time to pay, compromise claims and
settle Receivables and General Intangibles for less than face value and execute
all releases and other documents in connection therewith; (h) Pay any sums
required on account of Debtor's taxes or to secure the release of any liens
therefor, or both; (i) Settle and adjust, and give releases of, any insurance
claim that relates to any of the Collateral and obtain payment therefor; (j)
Instruct any third party having custody or control of any books or records
belonging to, or relating to, Debtor to give Silicon the same rights of access
and other rights with respect thereto as Silicon has under this Agreement; and
(k) Take any action or pay any sum required of Debtor pursuant to this Agreement
and any other present or future agreements. Any and all reasonable sums paid and
any and all reasonable costs, expenses, liabilities, obligations and reasonable
attorneys' fees incurred by Silicon with respect to the foregoing shall be added
to and become part of the Obligations, shall be payable on demand, and shall
bear interest at a rate equal to the highest interest rate applicable to any of
the Obligations. In no event shall Silicon's rights under the foregoing power of
attorney or any of Silicon's other rights under this Agreement be deemed to
indicate that Silicon is in control of the business, management or properties of
Debtor.

     5.5  Application of Proceeds. All proceeds realized as the result of any
sale or other disposition of the Collateral shall be applied by Silicon first to
the reasonable costs, expenses, liabilities, obligations and attorneys' fees
incurred

--------------------------------------------------------------------------------

by Silicon in the exercise of its rights under this Agreement, second to the
interest due upon any of the Obligations, and third to the principal of the
Obligations, in such order as Silicon shall determine in its sole discretion.
Any surplus shall be paid to Debtor or other persons legally entitled thereto;
Debtor shall remain liable to Silicon for any deficiency. If Silicon, in its
sole discretion, directly or indirectly enters into a deferred payment or other
credit transaction with any purchaser at any sale of Collateral, Silicon shall
have the option, exercisable at any time, in its sole discretion, of either
reducing the Obligations by the principal amount of purchase price or deferring
the reduction of the Obligations until the actual receipt by Silicon of the cash
therefor.

     5.6  Remedies Cumulative. In addition to the rights and remedies set forth
in this Agreement, Silicon shall have all the other rights and remedies accorded
a secured party under the California Uniform Commercial Code and under all other
applicable laws, and under any other instrument or agreement now or in the
future entered into between Silicon and Debtor, and all of such rights and
remedies are cumulative and none is exclusive. Exercise or partial exercise by
Silicon of one or more of its rights or remedies shall not be deemed an
election, nor bar Silicon from subsequent exercise or partial exercise of any
other rights or remedies. The failure or delay of Silicon to exercise any rights
or remedies shall not operate as a waiver thereof, but all rights and remedies
shall continue in full force and effect until all of the Obligations have been
fully paid and performed.

6.   Definitions. As used in this Agreement, the following terms have the
following meanings:

     "Account Debtor" means the obligor on a Receivable.
      --------------

7.   GENERAL PROVISIONS.

     7.1  Application of Payments. All payments with respect to the Obligations

Obligations, in such order and manner as Silicon shall determine in its sole
discretion.

     7.2  Notices. All notices to be given under this Agreement shall be in
writing and shall be given either personally or by reputable private delivery
service or by regular first-class mail, or certified mail return receipt
requested, or by facsimile addressed to Silicon or Debtor at the addresses shown
in the heading to this Agreement, or at any other address designated in writing
by one party to the other party. All notices shall be deemed to have been given
upon delivery in the case of notices personally delivered, upon confirmation of
receipt in the case of notices sent via facsimile, or at the expiration of one
business day following delivery to the private delivery service, or two business
days following the deposit thereof in the United States mail, with postage
prepaid.

     7.3  Severability. Should any provision of this Agreement be held by any
court of competent jurisdiction to be void or unenforceable, such defect shall
not affect the remainder of this Agreement, which shall continue in full force
and effect.

     7.4  Integration. This Agreement and such other written agreements,
documents and instruments as may be executed in connection herewith are the
final, entire and complete agreement between Debtor and Silicon and supersede
all prior and contemporaneous negotiations and oral representations and
agreements, all of which are merged and integrated in this Agreement. There are

no oral understandings, representations or agreements between the parties which
-------------------------------------------------------------------------------
are not set forth in this Agreement or in other written agreements signed by the
--------------------------------------------------------------------------------
parties in connection herewith.
------------------------------

     7.5  Waivers. The failure of Silicon at any time or times to require Debtor
to strictly comply with any of the provisions of this Agreement or any other
present or future agreement between Debtor and Silicon shall not waive or
diminish any right of Silicon later to demand and receive strict compliance
therewith. Any waiver of any default shall not waive or affect any other
default, whether prior or subsequent, and whether or not similar. None of the
provisions of this Agreement or any other agreement now or in the future
executed by Debtor and delivered to Silicon shall be deemed to have been waived
by any act or knowledge of Silicon or its agents or employees, but only by a
specific written waiver signed by an authorized officer of Silicon and delivered
to Debtor. Debtor waives demand, protest, notice of protest and notice of
default or dishonor, notice of payment and nonpayment, release, compromise,
settlement, extension or renewal of any commercial paper, instrument, account,
General Intangible, document or guaranty at any time held by Silicon on which
Debtor is or may in any way be liable, and notice of any action taken by
Silicon, unless expressly required by this Agreement.

     7.6  Amendment. The terms and provisions of this Agreement may not be
waived or amended, except in a writing executed by Debtor and a duly authorized
officer of Silicon.

of each and every obligation under this Agreement.

appraisal, audit, and other

                                      -7-
<PAGE>

Silicon Valley Bank                                           Security Agreement
--------------------------------------------------------------------------------

reasonable costs incurred by Silicon, pursuant to, or in connection with, or
relating to this Agreement (whether or not a lawsuit is filed), including, but
not limited to, any reasonable attorneys' fees and costs Silicon incurs in order
to do the following: prepare and negotiate this Agreement and the documents
relating to this Agreement; obtain legal advice in connection with this
Agreement or Debtor; enforce, or seek to enforce, any of its rights; prosecute
actions against, or defend actions by, Account Debtors; commence, intervene in,
or defend any action or proceeding; initiate any complaint to be relieved of the
automatic stay in bankruptcy; file or prosecute any probate claim, bankruptcy
claim, third-party claim, or other claim; examine, audit, copy, and inspect any
of the Collateral or any of Debtor's books and records; protect, obtain
possession of, lease, dispose of, or otherwise enforce Silicon's security
interest in, the Collateral; and otherwise represent Silicon in any litigation
relating to Debtor. If either Silicon or Debtor files any lawsuit against the
other predicated on a breach of this Agreement, the prevailing party in such
action shall be entitled to recover its reasonable costs and attorneys' fees,
including (but not limited to) reasonable attorneys' fees and costs incurred in
the enforcement of, execution upon or defense of any order, decree, award or
judgment. All attorneys' fees and costs to which Silicon may be entitled
pursuant to this Paragraph shall immediately become part of Debtor's
Obligations, shall be due on demand, and shall bear interest at a rate equal to
the highest interest rate applicable to any of the Obligations.

     7.9   Benefit of Agreement. The provisions of this Agreement shall be
binding upon and inure to the benefit of the respective successors, assigns,
heirs, beneficiaries and representatives of Debtor and Silicon; provided,
however, that Debtor may not assign or transfer any of its rights under this
Agreement without the prior written consent of Silicon, and any prohibited
assignment shall be void. No consent by Silicon to any assignment shall release
Debtor from its liability for the Obligations.

     7.10  Joint and Several Liability. If Debtor consists of more than one
Person, their liability shall be joint and several, and the compromise of any
claim with, or the release of, any Debtor shall not constitute a compromise
with, or a release of, any other Debtor.

     7.11  Limitation of Actions. Any claim or cause of action by Debtor against
Silicon, its directors, officers, employees, agents, accountants or attorneys,
based upon, arising from, or relating to this Agreement, or any other present or
future document or agreement, or any other transaction contemplated hereby or
thereby or relating hereto or thereto, or any other matter, cause or thing
whatsoever, occurred, done, omitted or suffered to be done by Silicon, its
directors, officers, employees, agents, accountants or attorneys, shall be
barred unless asserted by Debtor by the commencement of an action or proceeding
in a court of competent jurisdiction by the filing of a complaint within one
year after the first act, occurrence or omission upon which such claim or cause
of action, or any part thereof, is based, and the service of a summons and
complaint on an officer of Silicon, or on any other person authorized to accept
service on behalf of Silicon, within thirty (30) days thereafter. Debtor agrees
that such one-year period is a reasonable and sufficient time for Debtor to
investigate and act upon any such claim or cause of action. The one-year period
provided herein shall not be waived, tolled, or extended except by the written
consent of Silicon in its sole discretion. This provision shall survive any
termination of this Agreement or any other present or future agreement.

     7.12  Paragraph Headings; Construction. Paragraph headings are only used in
this Agreement for convenience. Debtor and Silicon acknowledge that the headings
may not describe completely the subject matter of the applicable paragraph, and
the headings shall not be used in any manner to construe, limit, define or
interpret any term or provision of this Agreement. The term "including",
whenever used in this Agreement, shall mean "including (but not limited to)".
This Agreement has been fully reviewed and negotiated between the parties and no
uncertainty or ambiguity in any term or provision of this Agreement shall be
construed strictly against Silicon or Debtor under any rule of construction or
otherwise.

     7.13  Governing Law; Jurisdiction; Venue. This Agreement and all acts and
transactions hereunder and all rights and obligations of Silicon and Debtor
shall be governed by the laws of the State of California. As a material part of
the consideration to Silicon to enter into this Agreement, Debtor (i) agrees
that all actions and proceedings relating directly or indirectly to this
Agreement shall, at Silicon's option, be litigated in courts located within
California, and that the exclusive venue therefor shall be Los Angeles County;
(ii) consents to the jurisdiction and venue of any such court and consents to
service of process in any such action or proceeding by personal delivery or any
other method permitted by law; and (iii) waives any and all rights Debtor may
have to object to the jurisdiction of any such court, or to transfer or change
the venue of any such action or proceeding.

     7.14  Mutual Waiver of Jury Trial. DEBTOR AND SILICON EACH HEREBY WAIVE THE
RIGHT TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING BASED UPON, ARISING OUT OF,
OR IN ANY WAY RELATING TO, THIS AGREEMENT OR ANY OTHER PRESENT OR FUTURE
INSTRUMENT OR AGREEMENT BETWEEN SILICON AND DEBTOR, OR ANY CONDUCT, ACTS OR
OMISSIONS OF SILICON OR DEBTOR OR ANY OF THEIR DIRECTORS, OFFICERS, EMPLOYEES,
AGENTS, ATTORNEYS OR ANY OTHER PERSONS AFFILIATED WITH SILICON OR DEBTOR, IN ALL
OF THE FOREGOING CASES, WHETHER SOUNDING IN CONTRACT OR TORT OR OTHERWISE.

                                 AMENDMENT NO. 2
                                     TO THE
                       KULICKE AND SOFFA INDUSTRIES, INC.
                      1994 EMPLOYEE INCENTIVE STOCK OPTION
                       AND NON-QUALIFIED STOCK OPTION PLAN

     WHEREAS, Kulicke and Soffa Industries, Inc. (the "Company") maintains the
Kulicke and Soffa Industries, Inc. 1994 Employee Incentive Stock Option and
Non-Qualified Stock Option Plan (the "Plan"), as amended and restated effective
October 8, 1996, and as amended one time thereafter, for the benefit of its
eligible employees and eligible employees of its subsidiaries;

     WHEREAS, the Company reserved the right to amend the Plan at any time,
subject to certain inapplicable limitations;

     WHEREAS, the Company desires to amend the Plan in order (i) to clarify the
method of paying the exercise price of options granted under the Plan, and (ii)
to add a service requirement to the definition of "Retirement";

     NOW, THEREFORE, with respect to options granted on or after May 16, 2000,
the Kulicke and Soffa Industries, Inc. 1994 Employee Incentive Stock Option and
Non-Qualified Stock Option Plan is hereby amended as follows:

     1. The first sentence of Subparagraph (b)(4)(B) (Manner of Payment) of
Section 6 (Options) is amended to read as follows:

     The Option price shall be payable:

               (i) In cash or its equivalent;

               (ii) In Common Shares previously acquired by the Key Employee;
          provided that if such Common Shares were acquired through the exercise
          of an ISO or NQSO, such shares have been held by the Key Employee for
          such period of time as required to be considered "mature" shares for
          purposes of accounting treatment; or

               (iii) In any combination of (i) and (ii) above.

     2. The last paragraph of Subparagraph (b)(5a) (Exercise upon Retirement of
Key Employee) of Section 6 (Options) is amended to read as follows:

<PAGE>

          For purposes of this Plan, Retirement shall mean a Key Employee's
     retirement from the Company and its Subsidiaries at or after attaining age
     65 and completing at least five years of employment with the Company and
     its Subsidiaries, or before such time if expressly agreed to by the
     Company.

     3. The second paragraph of Paragraph (e) (Withholding and Use of Shares to
Satisfy Tax Obligations) of Section 12 (Miscellaneous) is amended to read as
follows:

          In order to satisfy the withholding requirements of applicable federal
     tax laws, Key Employees may satisfy the minimum required federal
     withholding tax, in whole or in part, by returning to the Company Common
     Shares, which shares shall be valued, for this purpose, at their Fair
     Market Value on the date of exercise of the Option (or if later, the date
     on which the Key Employee recognizes ordinary income with respect to such
     exercise) ("Determination Date"). Alternatively, the Committee, in its
     discretion, may permit the Key Employee to satisfy the minimum required
     federal withholding tax, in whole or in part, by electing to have the
     Company withhold Common Shares. An election to use Common Shares to satisfy
     tax withholding requirements must be made in compliance with and subject to
     any withholding rules adopted by the Committee. The Company may not
     withhold shares in excess of the number necessary to satisfy the minimum
     required federal income tax withholding requirements. In the event Common
     Shares acquired under the exercise of an Option, granted under this Plan or
     any other plan of the Company, are used to satisfy such withholding
     requirement, such Common Shares must have been held by the Key Employee for
     such period of time as required to be considered "mature" shares for
     purposes of accounting treatment.

     IN WITNESS WHEREOF, Kulicke and Soffa Industries, Inc. has caused this
Amendment No. 2 to be executed this _______ day of ________________, 2000.
