Address:  1800 Robert Fulton Drive, Suite 250
          Reston, Virginia 20191

Date: July 31, 2000

     THIS PLEDGE AGREEMENT ("Pledge Agreement"), dated the above date, is
entered into between SILICON VALLEY BANK ("Silicon"), whose address is 3003
Tasman Drive, Santa Clara, CA 95054, and the pledgor named above ("Pledgor"),
whose address is set forth above.

     1.   Pledge of Securities. Pledgor shall concurrently deliver to Silicon
the stock certificates and other securities listed on Exhibit A hereto, together
with duly executed instruments of assignment thereof to Silicon (which together
with all replacements and substitutions therefor are hereinafter referred to as
the "Securities") provided, however, if no Event of Default has occurred,
Pledgor shall be allowed to sell the Securities within the first 90 days after
the date of this Agreement; therefore, Pledgor shall be allowed to retain
possession of the Securities for 90 days after the date of this Agreement, and
immediately thereafter, Pledgor shall deliver the Securities, or the remaining
portion thereof, to Silicon in accordance with the terms hereof. Pledgor hereby
pledges to Silicon and grants Silicon a security interest in the Securities, and
all rights and remedies relating to, or arising out of, any and all of the
foregoing, and all proceeds thereof and all replacements and substitutions
therefor (collectively, the "Collateral") to secure the payment and performance
of all debts, duties, obligations, liabilities, representations, warranties and
guaranties of Pledgor to Silicon, heretofore, now, or hereafter made, incurred
or created, of every kind and nature (collectively, the "Obligations"),
including, but not limited to, those arising under the Continuing Guaranty of
even date with respect to NetPlex Systems, Inc. (the "Guaranty"). Any and all
stock dividends, rights, warrants, options, puts, calls, conversion rights and
other securities and any and all property and money distributed or delivered
with respect to the Securities or issued upon the exercise of any puts, calls,
conversion rights, options, warrants or other rights included in or pertaining
to the Securities shall be included in the term "Securities" as used herein and
shall be subject to this Pledge Agreement, and Pledgor shall deliver the same to
Silicon immediately upon receipt thereof together with any necessary instruments
of transfer. Pledgor hereby acknowledges that the acceptance of the pledge of
the Securities by Silicon shall not constitute a commitment of any kind by
Silicon to permit Pledgor to incur Obligations.

     *provided however, if no Event of Default has occurred, Pledgor shall be
allowed to sell the Securities within the first 90 days after the date of this
Agreement: therefore, Pledgor shall be allowed to retain possession of the
Securities for 90 days after the date of this Agreement, and immediately
thereafter, Pledgor shall deliver the Securities, of the remaining portion
thereof, to Silicon in accordance with the terms hereof.

     2.   Voting and Other Rights. Pledgor shall have the right to exercise all
voting rights with respect to the Securities, provided no Event of Default (as
hereinafter defined) has occurred. Upon the occurrence of any Event of Default,
Silicon shall have the right (but not any obligation) to exercise all voting
rights with respect to the Securities. Provided no Event of Default has
occurred, Pledgor shall have the right to exercise all puts, calls, straddles,
conversion rights, options, warrants, and other rights and remedies with respect
to the Securities, provided Pledgor obtains the prior written consent of Silicon
thereto. Silicon shall have no responsibility or liability whatsoever for the
exercise of, or failure to exercise, any puts, calls, straddles, conversion
rights, options, warrants, rights to vote or consent, or other rights with
respect to any of the Securities. Whether or not an Event of Default has
occurred, Silicon shall have the right from time to time to transfer all or any
part of the Securities to Silicon's own name or the name of its nominee.

     3.   Representations and Warranties. Pledgor hereby represents and warrants
to Silicon that Pledgor now has, and throughout the term of this Agreement will
at all times have, good title to the Securities and the other Collateral, free
and clear of any and all security interests, liens and claims of any kind
whatsoever.

     4.   Events of Default. If any one or more of the following events shall
occur, any such event shall constitute an Event of Default and Pledgor shall
provide Silicon with immediate notice thereof: (a) Any warranty, representation,
statement, report or certificate made or

                                      -1-

     Silicon Valley Bank                                       Pledge Agreement
     --------------------------------------------------------------------------

delivered to Silicon by Pledgor or any of Pledgor's officers, employees or
agents now or hereafter is incorrect, false, untrue or misleading in any
material respect; or (b) Pledgor shall fail to promptly pay or perform when due
part or all of any of the Obligations within any applicable cure period, or any
event of default shall occur under the Guaranty or any other present or future
instrument, document or agreement between Silicon and Pledgor.

     5.   Remedies. If an Event of Default shall occur, Pledgor shall give
immediate written notice thereof to Silicon. Upon the occurrence of an Event of
Default, and at any time thereafter, Silicon shall have the right, without
notice to or demand upon Pledgor, to exercise any one or more of the following
remedies: (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 agreement or instrument evidencing or
relating to any of the same; (b) sell or otherwise dispose of the Securities,
and other Collateral, in any market on which they are traded, through the Broker
or otherwise, and obtain payment of the proceeds thereof, (c) sell or otherwise
dispose of the Securities, and other Collateral, at a public or private sale,
for cash, or other property, or on credit, with the authority to adjourn or
postpone any such sale from time to time without notice other than oral
announcement at the time scheduled for sale. Silicon may directly or through any
affiliate purchase the Securities, and other Collateral, at any such public
disposition, and if permissible under applicable law, at any private
disposition. Pledgor and Silicon hereby agree that it shall conclusively be
deemed commercially reasonable for Silicon, in connection with any sale or
disposition of the Securities, to impose restrictions and conditions as to the
investment intent of a purchaser or bidder, the ability of a purchaser or bidder
to bear the economic risk of an investment in the Securities, the knowledge and
experience in business and financial matters of a purchaser or bidder, the
access of a purchaser or bidder to information concerning the issuer of the
Securities, as well as legend conditions and stop transfer instructions
restricting subsequent transfer of the Securities, and any other restrictions or
conditions which Silicon believes to be necessary or advisable in order to
comply with any state or federal securities or other laws. Pledgor acknowledges
that the foregoing restrictions may result in fewer proceeds being received upon
such sale then would otherwise be the case. Pledgor hereby agrees to provide to
Silicon any and all information required by Silicon in connection with any sales
of Securities by Silicon hereunder. If, after the occurrence of any Event of
Default, Rule 144 promulgated by the Securities and Exchange Commission (or any
other similar rule) is available for use by Silicon in connection with the sales
of any Securities hereunder, Pledgor agrees not to utilize Rule 144 in the sale
of any securities held by Pledgor of the same class as the Securities, without
the prior written consent of Silicon. Any and all attorneys' fees, expenses,
costs, liabilities and obligations incurred by Silicon in connection with the
foregoing shall be added to and become a part of the Obligations and shall be
due from Pledgor to Silicon upon demand.

     6.   Remedies, Cumulative; No Waiver. The failure of Silicon to enforce any
of the provisions of this Agreement at any time or for any period of time shall
not be construed to be a waiver of any such provision or the right thereafter to
enforce the same. All remedies hereunder shall be cumulative and shall be in
addition to all rights, powers and remedies given to Silicon by law.

     7.   Term. This Agreement and Silicon's rights hereunder shall continue in
full force and effect until all of the Obligations have been fully paid,
performed and discharged and the Guaranty and all other agreements between
Borrower and Silicon have terminated. Upon termination, Silicon shall return the
Collateral to Pledgor, with any necessary instruments of transfer. Upon any sale
of the Securities by Pledgor, Silicon shall return the Collateral (or the
applicable portion thereof) necessary to complete such sale, together with any
necessary instruments of transfer.

     8.   General Provisions. This Agreement and the documents referred to
herein are the entire and only agreements between Pledgor and Silicon with
respect to the subject matter hereof, and all representations, warranties,
agreements, or undertakings heretofore or contemporaneously made, with respect
to the subject matter hereof, which are not set forth herein or therein, are
superseded hereby. The terms and provisions hereof may not be waived, altered,
modified, or amended except in a writing executed by Pledgor and Silicon. All
rights, benefits and privileges hereunder shall inure to the benefit of and be
enforceable by Silicon and its successors and assigns and shall be binding upon
Pledgor and its successors and assigns; provided that Pledgor may not transfer
any of its rights hereunder without the prior written consent of Silicon.
Paragraph headings are used herein for convenience only. Pledgor acknowledges
that the same may not describe completely the subject matter of the applicable
paragraph, and the same shall not be used in any manner to construe, limit,
define or interpret any term or provision hereof. Pledgor shall upon demand
reimburse Silicon for all reasonable costs, fees and expenses (including without
limitation attorneys' fees, whether or not suit be brought), which are incurred
by Silicon in connection with, or arising out of, this Agreement. This Agreement
and all acts and transactions pursuant hereto and the rights and obligations of
the parties hereto shall be governed, construed, and interpreted in accordance
with the internal laws (and not conflict of laws rules) of the State of
California. Pledgor hereby agrees that all actions or proceedings relating
directly or indirectly hereto may, at the option of Silicon,

be litigated in courts located within said State, and Pledgor hereby expressly
consents to the jurisdiction of any such court and consents to the service of
process in any such action or proceeding by personal delivery or by certified or
registered mailing directed to Pledgor at its last address known to Silicon.

     9.   Mutual Waiver of Right to Jury Trial. SILICON and Pledgor 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: (i) this Agreement; or (ii) any other present
or future instrument or agreement between SILICON and Pledgor; or (iii) any
conduct, acts or omissions of SILICON or Pledgor or any of their directors,
officers, employees, agents, attorneys or any other persons affiliated with
SILICON or Pledgor; in each of the foregoing cases, whether sounding in contract
or tort or otherwise.

Silicon Valley Bank

Continuing Guaranty

Borrower:  NetPlex Systems, Inc.

Guarantor: The NetPlex Group, Inc.
                America's Work Exchange, Inc.
                Contractors Resources, Inc.

Date:      July 31, 2000

   This Continuing Guaranty is executed by the above-named guarantor(s) (jointly
and severally, the "Guarantor"), as of the above date, in favor of SILICON
VALLEY BANK ("Silicon"), whose address is 3003 Tasman Drive, Santa Clara,
California 95054, with respect to the Indebtedness of the above-named borrower
("Borrower")

   1. Continuing Guaranty. Guarantor hereby unconditionally guarantees and
promises to pay on demand to Silicon, at the address indicated above, or at such
other address as Silicon may direct, in lawful money of the United States, and
to perform for the benefit of Silicon, all Indebtedness of Borrower now or
hereafter owing to or held by Silicon. As used herein, the term "Indebtedness"
is used in its most comprehensive sense and shall mean and include without
limitation: (a) any and all debts, duties, obligations, liabilities,
representations, warranties and guaranties of Borrower or any one or more of
them, heretofore, now, or hereafter made, incurred, or created, whether directly
to Silicon or acquired by Silicon by assignment or otherwise, or held by Silicon
on behalf of others, however arising, whether voluntary or involuntary, due or
not due, absolute or contingent, liquidated or unliquidated, certain or
uncertain, determined or undetermined, monetary or nonmonetary, written or oral,
and whether Borrower may be liable individually or jointly with others, and
regardless of whether recovery thereon may be or hereafter become barred by any
statute of limitations, discharged or uncollectible in any bankruptcy,
insolvency or other proceeding, or otherwise unenforceable; and (b) any and all
amendments, modifications, renewals and extensions of any or all of the
foregoing, including without limitation amendments, modifications, renewals and
extensions which are evidenced by any new or additional instrument, document or
agreement; and (c) any and all attorneys' fees, court costs, and collection
charges incurred in endeavoring to collect or enforce any of the foregoing
against Borrower, Guarantor, or any other person liable thereon (whether or not
suit be brought) and any other expenses of, for or incidental to collection
thereof. As used herein, the term "Borrower" shall include any successor to the
business and assets of Borrower, and shall also include Borrower in its capacity
as a debtor or debtor in possession under the federal Bankruptcy Code, and any
trustee, custodian or receiver for Borrower or any of its assets, should
Borrower hereafter become the subject of any bankruptcy or insolvency
proceeding, voluntary or involuntary; and all indebtedness, liabilities and
obligations incurred by any such person shall be included in the Indebtedness
guaranteed hereby. This Guaranty is given in consideration for credit and other
financial accommodations which may, from time to time, be given by Silicon to
Borrower in Silicon's sole discretion, but Guarantor acknowledges and agrees
that acceptance by Silicon of this Guaranty shall not constitute a commitment of
any kind by Silicon to extend such credit or other financial accommodation to
Borrower or to permit Borrower to incur Indebtedness to Silicon. All sums due
under this Guaranty shall bear interest from the date due until the date paid at
the highest rate charged with respect to any of the Indebtedness.

   2. Waivers. Guarantor hereby waives: (a) presentment for payment, notice of
dishonor, demand, protest, and notice thereof as to any instrument, and all
other notices and demands to which Guarantor might be entitled, including
without limitation notice of all of the following: the acceptance hereof; the
creation, existence, or acquisition of any Indebtedness; the amount of the
Indebtedness from time to time outstanding; any foreclosure sale or other
disposition of any property which secures any or all of the Indebtedness or
which secures the obligations of any other guarantor of any or all of the
Indebtedness; any adverse change in Borrower's financial position; any other
fact which might increase Guarantor's risk; any default, partial payment or
non-payment of all or any part of the

<PAGE>

           Silicon Valley Bank                          Continuing Guaranty
    ----------------------------------------------------------------------------

Indebtedness; the occurrence of any other Event of Default (as hereinafter
defined); any and all agreements and arrangements between Silicon and Borrower
and any changes, modifications, or extensions thereof, and any revocation,
modification or release of any guaranty of any or all of the Indebtedness by any
person (including without limitation any other person signing this Guaranty);
(b) any right to require Silicon to institute suit against, or to exhaust its
rights and remedies against, Borrower or any other person, or to proceed against
any property of any kind which secures all or any part of the Indebtedness, or
to exercise any right of offset or other right with respect to any reserves,
credits or deposit accounts held by or maintained with Silicon or any
indebtedness of Silicon to Borrower, or to exercise any other right or power, or
pursue any other remedy Silicon may have; (c) any defense arising by reason of
any disability or other defense of Borrower or any other guarantor or any
endorser, co-maker or other person, or by reason of the cessation from any cause
whatsoever of any liability of Borrower or any other guarantor or any endorser,
co-maker or other person, with respect to all or any part of the Indebtedness,
or by reason of any act or omission of Silicon or others which directly or
indirectly results in the discharge or release of Borrower or any other
guarantor or any other person or any Indebtedness or any security therefor,
whether by operation of law or otherwise; (d) any defense arising by reason of
any failure of Silicon to obtain, perfect, maintain or keep in force any
security interest in, or lien or encumbrance upon, any property of Borrower or
any other person; (e) any defense based upon any failure of Silicon to give
Guarantor notice of any sale or other disposition of any property securing any
or all of the Indebtedness, or any defects in any such notice that may be given,
or any failure of Silicon to comply with any provision of applicable law in
enforcing any security interest in or lien upon any property securing any or all
of the Indebtedness including, but not limited to, any failure by Silicon to
dispose of any property securing any or all of the Indebtedness in a
commercially reasonable manner; (f) any defense based upon or arising out of any
bankruptcy, insolvency, reorganization, arrangement, readjustment of debt,
liquidation or dissolution proceeding commenced by or against Borrower or any
other guarantor or any endorser, co-maker or other person, including without
limitation any discharge of, or bar against collecting, any of the Indebtedness
(including without limitation any interest thereon), in or as a result of any
such proceeding; and (g) the benefit of any and all statutes of limitation with
respect to any action based upon, arising out of or related to this Guaranty.
Until all of the Indebtedness has been paid, performed, and discharged in full,
nothing shall discharge or satisfy the liability of Guarantor hereunder except
the full performance and payment of all of the Indebtedness. If any claim is
ever made upon Silicon for repayment or recovery of any amount or amounts
received by Silicon in payment of or on account of any of the Indebtedness,
because of any claim that any such payment constituted a preferential transfer
or fraudulent conveyance, or for any other reason whatsoever, and Silicon repays
all or part of said amount by reason of any judgment, decree or order of any
court or administrative body having jurisdiction over Silicon or any of its
property, or by reason of any settlement or compromise of any such claim
effected by Silicon with any such claimant (including without limitation the
Borrower), then and in any such event, Guarantor agrees that any such judgment,
decree, order, settlement and compromise shall be binding upon Guarantor,
notwithstanding any revocation or release of this Guaranty or the cancellation
of any note or other instrument evidencing any of the Indebtedness, or any
release of any of the Indebtedness, and the Guarantor shall be and remain liable
to Silicon under this Guaranty for the amount so repaid or recovered, to the
same extent as if such amount had never originally been received by Silicon, and
the provisions of this sentence shall survive, and continue in effect,
notwithstanding any revocation or release of this Guaranty. Until all of the
Indebtedness has been irrevocably paid and performed in full, Guarantor hereby
expressly and unconditionally waives all rights of subrogation, reimbursement
and indemnity of every kind against Borrower, and all rights of recourse to any
assets or property of Borrower, and all rights to any collateral or security
held for the payment and performance of any Indebtedness, including (but not
limited to) any of the foregoing rights which Guarantor may have under any
present or future document or agreement with any Borrower or other person, and
including (but not limited to) any of the foregoing rights which Guarantor may
have under any equitable doctrine of subrogation, implied contract, or unjust
enrichment, or any other equitable or legal doctrine. Neither Silicon, nor any
of its directors, officers, employees, agents, attorneys or any other person
affiliated with or representing Silicon shall be liable for any claims, demands,
losses or damages, of any kind whatsoever, made, claimed, incurred or suffered
by Guarantor or any other party through the ordinary negligence of Silicon, or
any of its directors, officers, employees, agents, attorneys or any other person
affiliated with or representing Silicon.

   3. Consents. Guarantor hereby consents and agrees that, without notice to or
by Guarantor and without affecting or impairing in any way the obligations or
liability of Guarantor hereunder, Silicon may, from time to time before or after
revocation of this Guaranty, do any one or more of the following in Silicon's
sole and absolute discretion: (a) accelerate, accept partial payments of,
compromise or settle, renew, extend the time for the payment, discharge, or
performance of, refuse to enforce, and release all or any parties to, any or all
of the Indebtedness; (b) grant any other indulgence to Borrower or any other
person in respect of any or all of the Indebtedness or any other matter; (c)
accept, release, waive, surrender, enforce, exchange, modify, impair, or extend
the time for the performance, discharge, or payment of, any and all property of
any kind securing any or all of the Indebtedness or any guaranty of any or all
of the Indebtedness, or on which Silicon at any time may have a lien, or refuse
to enforce its rights or make any compromise or settlement or agreement therefor
in respect of any or all of such property; (d) substitute or add, or take any
action or omit to take any action which results in the release of, any one or
more endorsers or guarantors of

                                      -2-
<PAGE>

       Silicon Valley Bank                          Continuing Guaranty
----------------------------------------------------------------------------

all or any part of the Indebtedness, including, without limitation one or more
parties to this Guaranty, regardless of any destruction or impairment of any
right of contribution or other right of Guarantor; (e) amend, alter or change in
any respect whatsoever any term or provision relating to any or all of the
Indebtedness, including the rate of interest thereon; (f) apply any sums
received from Borrower, any other guarantor, endorser, or co-signer, or from the
disposition of any collateral or security, to any indebtedness whatsoever owing
from such person or secured by such collateral or security, in such manner and
order as Silicon determines in its sole discretion, and regardless of whether
such indebtedness is part of the Indebtedness, is secured, or is due and
payable; (g) apply any sums received from Guarantor or from the disposition of
any collateral or security securing the obligations of Guarantor, to any of the
Indebtedness in such manner and order as Silicon determines in its sole
discretion, regardless of whether or not such Indebtedness is secured or is due
and payable. Guarantor consents and agrees that Silicon shall be under no
obligation to marshal any assets in favor of Guarantor, or against or in payment
of any or all of the Indebtedness. Guarantor further consents and agrees that
Silicon shall have no duties or responsibilities whatsoever with respect to any
property securing any or all of the Indebtedness. Without limiting the
generality of the foregoing, Silicon shall have no obligation to monitor,
verify, audit, examine, or obtain or maintain any insurance with respect to, any
property securing any or all of the Indebtedness.

   4. Account Stated. Silicon's books and records showing the account between it
and the Borrower shall be admissible in evidence in any action or proceeding as
prima facie proof of the items therein set forth. Silicon's monthly statements
rendered to the Borrower shall be binding upon the Guarantor (whether or not the
Guarantor receives copies thereof), and shall constitute an account stated
between Silicon and the Borrower, unless Silicon receives a written statement of
the Borrower's exceptions within 30 days after the statement was mailed to the
Borrower. The Guarantor assumes full responsibility for obtaining copies of such
monthly statements from the Borrower, if the Guarantor desires such copies.

   5. Exercise of Rights and Remedies; Foreclosure of Trust Deeds. Guarantor
consents and agrees that, without notice to or by Guarantor and without
affecting or impairing in any way the obligations or liability of Guarantor
hereunder, Silicon may, from time to time, before or after revocation of this
Guaranty, exercise any right or remedy it may have with respect to any or all of
the Indebtedness or any property securing any or all of the Indebtedness or any
guaranty thereof, including without limitation judicial foreclosure, nonjudicial
foreclosure, exercise of a power of sale, and taking a deed, assignment or
transfer in lieu of foreclosure as to any such property, and Guarantor expressly
waives any defense based upon the exercise of any such right or remedy,
notwithstanding the effect thereof upon any of Guarantor's rights, including
without limitation, any destruction of Guarantor's right of subrogation against
Borrower and any destruction of Guarantor's right of contribution or other right
against any other guarantor of any or all of the Indebtedness or against any
other person, whether by operation of Sections 580a, 580d or 726 of the
California Code of Civil Procedure, or any comparable provisions of the laws of
any other jurisdiction, or any other statutes or rules of law now or hereafter
in effect, or otherwise. Without limiting the generality of the foregoing, (a)
The guarantor waives all rights and defenses that the Guarantor may have because
the Indebtedness is secured by real property. This means, among other things:
(1) Silicon may collect from the Guarantor without first foreclosing on any real
or personal property collateral pledged by the Borrower. (2) If Silicon
forecloses on any real property collateral pledged by the Borrower: (A) The
amount of the Indebtedness may be reduced only by the price for which that
collateral is sold at the foreclosure sale, even if the collateral is worth more
than the sale price. (B) Silicon may collect from the Guarantor even if Silicon,
by foreclosing on the real property collateral, has destroyed any right the
Guarantor may have to collect from the Borrower. This is an unconditional and
irrevocable waiver of any rights and defenses the Guarantor may have because the
Indebtedness is secured by real property. These rights and defenses include, but
are not limited to, any rights or defenses based upon Section 580a, 580b, 580d,
or 726 of the Code of Civil Procedure. (b) The guarantor waives all rights and
defenses that the Guarantor may have because the guaranty of another guarantor
is secured by real property. This means, among other things: (1) Silicon may
collect from the Guarantor without first foreclosing on any real or personal
property collateral pledged by the other guarantor. (2) If Silicon forecloses on
any real property collateral pledged by the other guarantor: (A) The amount of
the Indebtedness may be reduced only by the price for which that collateral is
sold at the foreclosure sale, even if the collateral is worth more than the sale
price. (B) Silicon may collect from the Guarantor even if Silicon, by
foreclosing on the real property collateral, has destroyed any right the
Guarantor may have to obtain contribution from the other guarantor. This is an
unconditional and irrevocable waiver of any rights and defenses the Guarantor
may have because the obligations of the other guarantor are secured by real
property. These rights and defenses include, but are not limited to, any rights
or defenses based upon Section 580a, 580b, 580d, or 726 of the Code of Civil
Procedure.

   6. Acceleration. Notwithstanding the terms of all or any part of the
Indebtedness, the obligations of the Guarantor hereunder to pay and perform all
of the Indebtedness shall, at the option of Silicon, immediately become due and
payable, without notice, and without regard to the expressed maturity of any of
the Indebtedness, in the event: (a) any warranty, representation, statement,
report, or certificate made or delivered to Silicon by Borrower or Guarantor, or
any of their respective officers, partners, employees, or agents, is incorrect,
false, untrue, or misleading when given in any material respect; or (b) Borrower
or Guarantor shall fail to pay or perform when due all or any part of the
Indebtedness; or (c) Guarantor

                                      -3-
<PAGE>

       Silicon Valley Bank                          Continuing Guaranty
----------------------------------------------------------------------------

shall fail to pay or perform when due any indebtedness or obligation of
Guarantor to Silicon or to any parent, subsidiary or corporate affiliate of
Silicon, whether under this Guaranty or any other instrument, document, or
agreement heretofore or hereafter entered into; or (d) there occurs in Silicon's
judgment a material impairment of the prospect of payment or performance of any
or all of the Indebtedness; or (e) any event shall occur which may or does
result in the acceleration of the maturity of any indebtedness of Borrower or
Guarantor to others (regardless of any requirement of notice, opportunity to
cure or other condition prior to the exercise of any right of acceleration); or
(f) Borrower or Guarantor shall fail promptly to perform or comply with any term
or condition of any agreement with any third party which does or may result in a
material adverse effect on the business of Borrower or Guarantor; which remains
uncured beyond any applicable cure period or (g) there shall be made or exist
any levy, assessment, attachment, seizure, lien, or encumbrance for any cause or
reason whatsoever upon all or any part of the property of Borrower or Guarantor
(unless discharged by payment, release or bond not more than ten days after such
event has occurred); or (h) there shall occur the dissolution, termination of
existence, insolvency, or business failure of Borrower or Guarantor, or the
appointment of a receiver, trustee or custodian for Borrower or Guarantor or all
or any part of the property of either of them, or the assignment for the benefit
of creditors by Borrower or Guarantor, or the commencement of any proceeding by
or against Borrower or Guarantor under any reorganization, bankruptcy,
insolvency, arrangement, readjustment of debt, dissolution or liquidation law or
statute of any jurisdiction, now or hereafter in effect; which with respect to
any such proceeding commenced against the Debtor or Borrower, is not dismissed
within 60 days of the commencement thereof or (i) Borrower or Guarantor shall be
deceased or declared incompetent by any court or a guardian or conservator shall
be appointed for either of them or for the property of either of them; or (j)
Guarantor or Borrower shall generally not pay their respective debts as they
become due or shall enter into any agreement (whether written or oral), or offer
to enter into any such agreement, with all or a significant number of its
creditors regarding any moratorium or other indulgence with respect to its debts
or the participation of such creditors or their representatives in the
supervision, management, or control of the business of either of them; or (k)
Borrower or Guarantor shall conceal, remove or permit to be concealed or removed
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 shall make any
transfer of its property to or for the benefit of any creditor at a time when
other creditors similarly situated have not been paid; or (l) the board of
directors or shareholders of Borrower or Guarantor shall adopt any resolution or
plan for its dissolution or the liquidation of all or substantially all of its
assets; or (m) Guarantor shall revoke this Guaranty or contest or deny liability
under this Guaranty. All of the foregoing are hereinafter referred to as "Events
of Default".

   7. Right to Attachment Remedy. Guarantor agrees that, notwithstanding the
existence of any property securing any or all of the Indebtedness, Silicon shall
have all of the rights of an unsecured creditor of Guarantor, including without
limitation the right to obtain a temporary protective order and writ of
attachment against Guarantor with respect to any sums due under this Guaranty.
Guarantor further agrees that in the event any property secures the obligations
of Guarantor under this Guaranty, to the extent that Silicon, in its sole and
absolute discretion, determines prior to the disposition of such property that
the amount to be realized by Silicon therefrom may be less than the indebtedness
of the Guarantor under this Guaranty, Silicon shall have all the rights of an
unsecured creditor against Guarantor, including without limitation the right of
Silicon, prior to the disposition of said property, to obtain a temporary
protective order and writ of attachment against Guarantor. Guarantor waives the
benefit of Section 483.010(b) of the California Code of Civil Procedure and of
any and all other statutes and rules of law now or hereafter in effect requiring
Silicon to first resort to or exhaust all such collateral before seeking or
obtaining any attachment remedy against Guarantor. Silicon shall have no
liability to Guarantor as a result thereof, whether or not the actual deficiency
realized by Silicon is less than the anticipated deficiency on the basis of
which Silicon obtains a temporary protective order or writ of attachment.

   8. Indemnity. Guarantor 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
without limitation attorneys' fees), of every nature, character and description,
which Silicon may sustain or incur based upon or arising out of any of the
Indebtedness, any actual or alleged failure to collect and pay over any
withholding or other tax relating to Borrower or its employees, any relationship
or agreement between Silicon and Borrower, any actual or alleged failure of
Silicon to comply with any writ of attachment or other legal process relating to
Borrower or any of its property, or any other matter, cause or thing whatsoever
occurred, done, omitted or suffered to be done by Silicon relating in any way to
Borrower or the Indebtedness (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
Guaranty to the contrary, the indemnity agreement set forth in this Section
shall survive any termination or revocation of this Guaranty and shall for all
purposes continue in full force and effect.

   9. Subordination. Any and all rights of Guarantor under any and all debts,
liabilities and obligations owing from Borrower to Guarantor, including any
security for and guaranties of any such obligations, whether now existing or

                                      -4-
<PAGE>

       Silicon Valley Bank                          Continuing Guaranty
----------------------------------------------------------------------------

hereafter arising, are hereby subordinated in right of payment to the prior
payment in full of all of the Indebtedness. No payment in respect of any such
subordinated obligations shall at any time be made to or accepted by Guarantor
if at the time of such payment any Indebtedness is outstanding. If any Event of
Default has occurred, Borrower and any assignee, trustee in bankruptcy,
receiver, or any other person having custody or control over any or all of
Borrower's property are hereby authorized and directed to pay to Silicon the
entire unpaid balance of the Indebtedness before making any payments whatsoever
to Guarantor, whether as a creditor, shareholder, or otherwise; and insofar as
may be necessary for that purpose, Guarantor hereby assigns and transfers to
Silicon all rights to any and all debts, liabilities and obligations owing from
Borrower to Guarantor, including any security for and guaranties of any such
obligations, whether now existing or hereafter arising, including without
limitation any payments, dividends or distributions out of the business or
assets of Borrower. Any amounts received by Guarantor in violation of the
foregoing provisions shall be received and held as trustee for the benefit of
Silicon and shall forthwith be paid over to Silicon to be applied to the
Indebtedness in such order and sequence as Silicon shall in its sole discretion
determine, without limiting or affecting any other right or remedy which Silicon
may have hereunder or otherwise and without otherwise affecting the liability of
Guarantor hereunder. Guarantor hereby expressly waives any right to set-off or
assert any counterclaim against Borrower.

   10. Revocation. This is a Continuing Guaranty relating to all of the
Indebtedness, including Indebtedness arising under successive transactions which
from time to time continue the Indebtedness or renew it after it has been
satisfied. Guarantor waives all benefits of California Civil Code Section 2815,
and agrees that the obligations of Guarantor hereunder may not be terminated or
revoked in any manner except by giving 90 days' advance written notice of
revocation to Silicon at its address above by registered first-class U.S. mail,
postage prepaid, return receipt requested, and only as to new loans made by
Silicon to Borrower more than 90 days after actual receipt of such written
notice by Silicon. No termination or revocation of this Guaranty shall be
effective until 90 days following the date of actual receipt of said written
notice of revocation by Silicon. Notwithstanding such written notice of
revocation or any other act of Guarantor or any other event or circumstance,
Guarantor agrees that this Guaranty and all consents, waivers and other
provisions hereof shall continue in full force and effect as to any and all
Indebtedness which is outstanding on or before the 90th day following actual
receipt of said written notice of revocation by Silicon, and all extensions,
renewals and modifications of said Indebtedness (including without limitation
amendments, extensions, renewals and modifications which are evidenced by new or
additional instruments, documents or agreements executed before or after
expiration of said 90-day period), and all interest thereon, accruing before or
after expiration of said 90-day period, and all attorneys' fees, court costs and
collection charges, incurred before or after expiration of said 90-day period,
in endeavoring to collect or enforce any of the foregoing against Borrower,
Guarantor or any other person liable thereon (whether or not suit be brought)
and any other expenses of, for or incidental to collection thereof.

   11. Independent Liability. Guarantor hereby agrees that one or more
successive or concurrent actions may be brought hereon against Guarantor, in the
same action in which Borrower may be sued or in separate actions, as often as
deemed advisable by Silicon. The liability of Guarantor hereunder is exclusive
and independent of any other guaranty of any or all of the Indebtedness whether
executed by Guarantor or by any other guarantor (including without limitation
any other persons signing this Guaranty). The liability of Guarantor hereunder
shall not be affected, revoked, impaired, or reduced by any one or more of the
following: (a) the fact that the Indebtedness exceeds the maximum amount of
Guarantor's liability, if any, specified herein or elsewhere (and no agreement
specifying a maximum amount of Guarantor's liability shall be enforceable unless
set forth in a writing signed by Silicon or set forth in this Guaranty); or (b)
any direction as to the application of payment by Borrower or by any other
party; or (c) any other continuing or restrictive guaranty or undertaking or any
limitation on the liability of any other guarantor (whether under this Guaranty
or under any other agreement); or (d) any payment on or reduction of any such
other guaranty or undertaking; or (e) any revocation, amendment, modification or
release of any such other guaranty or undertaking; or (f) any dissolution or
termination of, or increase, decrease, or change in membership of any Guarantor
which is a partnership. Guarantor hereby expressly represents that he was not
induced to give this Guaranty by the fact that there are or may be other
guarantors either under this Guaranty or otherwise, and Guarantor agrees that
any release of any one or more of such other guarantors shall not release
Guarantor from his obligations hereunder either in full or to any lesser extent.
If Guarantor is a married person, Guarantor hereby expressly agrees that
recourse may be had against his or her separate property for all of his or her
obligations hereunder.

   12. Financial Condition of Borrower. Guarantor is fully aware of the
financial condition of Borrower and is executing and delivering this Guaranty at
Borrower's request and based solely upon his own independent investigation of
all matters pertinent hereto, and Guarantor is not relying in any manner upon
any representation or statement of Silicon with respect thereto. Guarantor
represents and warrants that he is in a position to obtain, and Guarantor hereby
assumes full responsibility for obtaining, any additional information concerning
Borrower's financial condition and any other matter pertinent hereto as
Guarantor may desire, and Guarantor is not relying upon or expecting Silicon to
furnish to him any information now or hereafter in Silicon's possession
concerning the same or any other matter. By executing this Guaranty, Guarantor
knowingly accepts the full range of risks encompassed within a contract of
continuing guaranty, which risks Guarantor acknowledges include without
limitation the possibility that

                                      -5-
<PAGE>

       Silicon Valley Bank                          Continuing Guaranty
----------------------------------------------------------------------------

Borrower will incur additional Indebtedness for which Guarantor will be liable
hereunder after Borrower's financial condition or ability to pay such
Indebtedness has deteriorated and/or after bankruptcy or insolvency proceedings
have been commenced by or against Borrower. Guarantor shall have no right to
require Silicon to obtain or disclose any information with respect to the
Indebtedness, the financial condition or character of Borrower, the existence of
any collateral or security for any or all of the Indebtedness, the filing by or
against Borrower of any bankruptcy or insolvency proceeding, the existence of
any other guaranties of all or any part of the Indebtedness, any action or non-
action on the part of Silicon, Borrower, or any other person, or any other
matter, fact, or occurrence.

   13. Reports and Financial Statements of Guarantor. Guarantor shall, at its
sole cost and expense, at any time and from time to time, prepare or cause to be
prepared, and provide to Silicon upon Silicon's request (i) such financial
statements and reports concerning Guarantor for such periods of time as Silicon
may designate, (ii) any other information concerning Guarantor's business,
financial condition or affairs as Silicon may request, and (iii) copies of any
and all foreign, federal, state and local tax returns and reports of or relating
to Guarantor as Silicon may from time to time request. Guarantor hereby
intentionally and knowingly waives any and all rights and privileges it may have
not to divulge or deliver said tax returns, reports and other information which
are requested by Silicon hereunder or in any litigation in which Silicon may be
involved relating directly or indirectly to Borrower or to Guarantor. Guarantor
further agrees immediately to give written notice to Silicon of any adverse
change in Guarantor's financial condition and of any condition or event which
constitutes an Event of Default under this Guaranty. All reports and information
furnished to Silicon hereunder shall be complete, accurate and correct in all
respects. Whenever requested, Guarantor shall further deliver to Silicon a
certificate signed by Guarantor (and, if Guarantor is a partnership, by all
general partners of Guarantor, in their individual capacities, and, if Guarantor
is a corporation, by the president and secretary of Guarantor, in their
individual capacities) warranting and representing that all reports, financial
statements and other documents and information delivered or caused to be
delivered to Silicon under this Guaranty, are complete, correct and thoroughly
and accurately present the financial condition of Guarantor, and that there
exists on the date of delivery of said certificate to Silicon no condition or
event which constitutes an Event of Default under this Guaranty.

   14. Representations and Warranties. Guarantor hereby represents and warrants
that (i) it is in Guarantor's direct interest to assist Borrower in procuring
credit, because Borrower is an affiliate of Guarantor, furnishes goods or
services to Guarantor, purchases or acquires goods or services from Guarantor,
and/or otherwise has a direct or indirect corporate or business relationship
with Guarantor, (ii) this Guaranty has been duly and validly authorized,
executed and delivered and constitutes the valid and binding obligation of
Guarantor, enforceable in accordance with its terms, and (iii) the execution and
delivery of this Guaranty does not violate or constitute a default under (with
or without the giving of notice, the passage of time, or both) any order,
judgment, decree, instrument or agreement to which Guarantor is a party or by
which it or its assets are affected or bound.

   15. Costs. Whether or not suit be instituted, Guarantor agrees to reimburse
Silicon on demand for all reasonable attorneys' fees and all other reasonable
costs and expenses incurred by Silicon in enforcing this Guaranty, or arising
out of or relating in any way to this Guaranty, or in enforcing any of the
Indebtedness against Borrower, Guarantor, or any other person, or in connection
with any property of any kind securing all or any part of the Indebtedness.
Without limiting the generality of the foregoing, and in addition thereto,
Guarantor shall reimburse Silicon on demand for all reasonable attorneys' fees
and costs Silicon incurs in any way relating to Guarantor, Borrower or the
Indebtedness, in order to: obtain legal advice; enforce or seek to enforce any
of its rights; commence, intervene in, respond to, or defend any action or
proceeding; file, prosecute or defend any claim or cause of action in any action
or proceeding (including without limitation any probate claim, bankruptcy claim,
third-party claim, secured creditor claim, reclamation complaint, and complaint
for relief from any stay under the Bankruptcy Code or otherwise); protect,
obtain possession of, sell, lease, dispose of or otherwise enforce any security
interest in or lien on any property of any kind securing any or all of the
Indebtedness; or represent Silicon in any litigation with respect to Borrower's
or Guarantor's affairs. In the event either Silicon or Guarantor files any
lawsuit against the other predicated on a breach of this Guaranty, the
prevailing party in such action shall be entitled to recover its attorneys' fees
and costs of suit from the non-prevailing party.

   16. Notices. Any notice which a party shall be required or shall desire to
give to the other hereunder (except for notice of revocation, which shall be
governed by Section 10 of this Guaranty) shall be given by personal delivery or
by telecopier or by depositing the same in the United States mail, first class
postage pre-paid, addressed to Silicon at its address set forth in the heading
of this Guaranty and to Guarantor at his address set forth under his signature
hereon, and such notices shall be deemed duly given on the date of personal
delivery or upon confirmation of receipt if telecopied or 3 business days after
the date of mailing as aforesaid. Silicon and Guarantor may change their address
for purposes of receiving notices hereunder by giving written notice thereof to
the other party in accordance herewith. Guarantor shall give Silicon immediate
written notice of any change in his address.

   17. Claims. Guarantor agrees that any claim or cause of action by Guarantor
against Silicon, or any of Silicon's directors, officers, employees, agents,
accountants or

                                      -6-
<PAGE>

       Silicon Valley Bank                          Continuing Guaranty
----------------------------------------------------------------------------

attorneys, based upon, arising from, or relating to this Guaranty, or any other
present or future agreement between Silicon and Guarantor or between Silicon and
Borrower, or any other transaction contemplated hereby or thereby or relating
hereto or thereto, or any other matter, cause or thing whatsoever, whether or
not relating hereto or thereto, occurred, done, omitted or suffered to be done
by Silicon, or by Silicon's directors, officers, employees, agents, accountants
or attorneys, whether sounding in contract or in tort or otherwise, shall be
barred unless asserted by Guarantor by the commencement of an action or
proceeding in a court of competent jurisdiction within Santa Clara County,
California, 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 service of a summons and complaint on an officer of
Silicon or any other person authorized to accept service of process on behalf of
Silicon, within 30 days thereafter. Guarantor agrees that such one year period
is a reasonable and sufficient time for Guarantor 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 a specific written agreement of
Silicon. This provision shall survive any termination of this Guaranty or any
other agreement.

   18. Construction; Severability. If more than one person has executed this
Guaranty, the term "Guarantor" as used herein shall be deemed to refer to all
and any one or more such persons and their obligations hereunder shall be joint
and several. Without limiting the generality of the foregoing, if more than one
person has executed this Guaranty, this Guaranty shall in all respects be
interpreted as though each person signing this Guaranty had signed a separate
Guaranty, and references herein to "other guarantors" or words of similar effect
shall include without limitation other persons signing this Guaranty. As used in
this Guaranty, the term "property" is used in its most comprehensive sense and
shall mean all property of every kind and nature whatsoever, including without
limitation real property, personal property, mixed property, tangible property
and intangible property. Words used herein in the masculine gender shall include
the neuter and feminine gender, words used herein in the neuter gender shall
include the masculine and feminine, words used herein in the singular shall
include the plural and words used in the plural shall include the singular,
wherever the context so reasonably requires. If any provision of this Guaranty
or the application thereof to any party or circumstance is held invalid, void,
inoperative or unenforceable, the remainder of this Guaranty and the application
of such provision to other parties or circumstances shall not be affected
thereby, the provisions of this Guaranty being severable in any such instance.

   19. General Provisions. Silicon shall have the right to seek recourse against
Guarantor to the full extent provided for herein and in any other instrument or
agreement evidencing obligations of Guarantor to Silicon, and against Borrower
to the full extent of the Indebtedness. No election in one form of action or
proceeding, or against any party, or on any obligation, shall constitute a
waiver of Silicon's right to proceed in any other form of action or proceeding
or against any other party. The failure of Silicon to enforce any of the
provisions of this Guaranty at any time or for any period of time shall not be
construed to be a waiver of any such provision or the right thereafter to
enforce the same. All remedies hereunder shall be cumulative and shall be in
addition to all rights, powers and remedies given to Silicon by law or under any
other instrument or agreement. Time is of the essence in the performance by
Guarantor of each and every obligation under this Guaranty. If Borrower is a
corporation, partnership or other entity, Guarantor hereby agrees that Silicon
shall have no obligation to inquire into the power or authority of Borrower or
any of its officers, directors, partners, or agents acting or purporting to act
on its behalf, and any Indebtedness made or created in reliance upon the
professed exercise of any such power or authority shall be included in the
Indebtedness guaranteed hereby. This Guaranty is the entire and only agreement
between Guarantor and Silicon with respect to the guaranty of the Indebtedness
of Borrower by Guarantor, and all representations, warranties, agreements, or
undertakings heretofore or contemporaneously made, which are not set forth
herein, are superseded hereby. No course of dealings between the parties, no
usage of the trade, and no parol or extrinsic evidence of any nature shall be
used or be relevant to supplement or explain or modify any term or provision of
this Guaranty. There are no conditions to the full effectiveness of this
Guaranty. The terms and provisions hereof may not be waived, altered, modified,
or amended except in a writing executed by Guarantor and a duly authorized
officer of Silicon. All rights, benefits and privileges hereunder shall inure to
the benefit of and be enforceable by Silicon and its successors and assigns and
shall be binding upon Guarantor and his heirs, executors, administrators,
personal representatives, successors and assigns. Neither the death of Guarantor
nor notice thereof to Silicon shall terminate this Guaranty as to his estate,
and, notwithstanding the death of Guarantor or notice thereof to Silicon, this
Guaranty shall continue in full force and effect with respect to all
Indebtedness, including without limitation Indebtedness incurred or created
after the death of Guarantor and notice thereof to Silicon. Section headings are
used herein for convenience only. Guarantor acknowledges that the same may not
describe completely the subject matter of the applicable Section, and the same
shall not be used in any manner to construe, limit, define or interpret any term
or provision hereof.

   20. Governing Law; Venue and Jurisdiction. This instrument and all acts and
transactions pursuant or relating hereto and all rights and obligations of the
parties hereto shall be governed, construed, and interpreted in accordance with
the internal laws of the State of California. In order to induce Silicon to
accept this Guaranty, and as a material part of the consideration therefor,
Guarantor (i) agrees that all actions or proceedings relating directly or
indirectly hereto shall, at the option of Silicon, be litigated in courts
located within Santa Clara County, California, (ii) consents

                                      -7-

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

to the jurisdiction of any such court and consents to the 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 Guarantor may have to transfer or
change the venue of any such action or proceeding.

   21. Mutual Waiver of Right to Jury Trial. SILICON AND GUARANTOR HEREBY WAIVE
THE RIGHT TO TRIAL BY JURY IN ANY ACTION, CLAIM, LAWSUIT OR PROCEEDING BASED
UPON, ARISING OUT OF, OR IN ANY WAY RELATING TO: (i) THIS GUARANTEE OR ANY
SUPPLEMENT OR AMENDMENT THERETO; OR (ii) ANY OTHER PRESENT OR FUTURE INSTRUMENT
OR AGREEMENT BETWEEN SILICON AND GUARANTOR; OR (iii) ANY BREACH, CONDUCT, ACTS
OR OMISSIONS OF SILICON or GUARANTOR OR ANY OF THEIR RESPECTIVE DIRECTORS,
OFFICERS, EMPLOYEES, AGENTS, ATTORNEYS OR ANY OTHER PERSON AFFILIATED WITH OR
REPRESENTING SILICON or GUARANTOR; IN EACH OF THE FOREGOING CASES, WHETHER
SOUNDING IN CONTRACT OR TORT OR OTHERWISE.

   22. Receipt of Copy. Guarantor acknowledges receipt of a copy of this
Guaranty.

     WHEREAS, it is in the direct interest of this corporation to assist the
