                         GUARANTY AND SECURITY AGREEMENT


      This Guaranty and Security Agreement (this "Agreement"), dated as of
December 15, 2000, is made by each of the undersigned (herein collectively
called "Guarantor") in favor of Foothill Capital Corporation, a California
corporation, as Agent for itself and Lenders, and the other Lenders
("Foothill"), pursuant to that certain Loan and Security Agreement (the "Loan
Agreement"), dated as of December 15, 2000, by and among Communication & Power
Industries, Inc., a Delaware corporation ("Debtor"), the other Obligors
(including the undersigned) named therein, Foothill and the other Lenders named
herein (Foothill and the other Lenders are collectively referred to herein as
"Lender"). Capitalized terms, which are used herein but not defined herein,
shall have the meanings ascribed to them in the Loan Agreement.

      Guarantor, at the solicitation of Debtor, requests that Lender extend
Credit to Debtor and in consideration of Credit heretofore, now or hereafter
granted to Debtor by Lender, Guarantor agrees as follows:

      1.    The term "Credit" is used throughout this Agreement in its most
comprehensive sense and means and includes, without limitation, any and all
loans, advances, debts, obligations and liabilities of any kind or nature owed
by Debtor to Lender (including, without, limitation, the Obligations) and any
and all future Obligations owing by Debtor to Lender and all other financial
accommodations extended by Lender to Debtor, heretofore, now, or hereafter made,
incurred or created, whether voluntary or involuntary and however arising,
whether owed directly to Lender or acquired by Lender by assignment,
subrogation, or succession (including, without limitation, Lender participations
and interests of Lender in the obligations of Debtor to others), whether due or
not due, absolute or contingent, liquidated or unliquidated, determined or
undetermined, secured or unsecured, whether on original, renewed, extended or
revised terms (including, without limitation, those evidenced by new or
additional instruments or agreements or those changing the applicable rate of
interest or which release any obligor with respect thereto), whether principal,
interest (including any interest that, but for the provisions of the U.S.
Bankruptcy Code would have accrued) or fees, whether Debtor may be liable
individually or jointly with others, whether recovery upon such indebtedness may
be or hereafter become barred by any statute of limitations, and whether such
indebtedness may be or hereafter become invalid or otherwise unenforceable. In
the event a petition under the U.S. Bankruptcy Code is filed by or against
Debtor, the term "Debtor" shall also mean and include Debtor in its status as a
debtor, debtor-in-possession and/or reorganized debtor under the U.S. Bankruptcy
Code.

      2.    If there is more than a single person included in the terms
"Guarantor" or "Debtor," respectively, (a) each reference herein to such terms
shall mean all and any one or more of such entities and persons both jointly and
severally, and (b) if more than one entity executes this Agreement, the
obligations and liabilities hereunder of Guarantors are and shall be both joint
and several. If Debtor is a partnership or association, each reference herein to
the term "Debtor" shall



                                      -1-
   2

include any successor entity to Debtor. As used in this Agreement, neuter terms
include the masculine and feminine, and vice versa.

      3.    Guarantor's liability hereunder shall be unlimited. Without limiting
the foregoing and in addition thereto, Guarantor agrees to bear and be liable to
Lender for the interest and expenses enumerated in paragraph 17 hereof.

      4.    Guarantor unconditionally guarantees and agrees to pay Lender or its
order, on demand, in lawful money of the United States of America, an amount
equal to the amount of the Credit, and to otherwise perform any obligation of
Debtor undertaken pursuant to any Credit. This Agreement is a guaranty of
payment and not of collection.

      5.    Either before or after revocation hereof, Guarantor authorizes
Lender at its sole discretion, with or without notice, and without affecting
Guarantor's continuing liability hereunder, from time to time to (a) change the
time or manner of payment of any Credit by renewal, extension, acceleration or
otherwise, (b) alter or change any other provision of any Credit including the
rate of interest thereon, (c) accept partial payment on any Credit, (d) accept
new or additional instruments, agreements or documents relative to any Credit,
(e) release, substitute or add one or more endorsers, cosigners or guarantors
for any Credit, (f) amend or modify the terms of any guaranty executed by a
co-guarantor, including the maximum liability thereunder, (g) obtain collateral
for the payment of any Credit and/or any guaranty thereof, (h) waive, release,
exchange, substitute, release or modify, in whole or in part, existing or
after-acquired collateral securing payment of the Credit or any guaranty
therefor on such terms as Lender in its sole discretion shall determine, (i)
subordinate payment of all or any part of the Credit to other creditors of
Debtor or other persons on such terms as Lender deems appropriate, (j) apply any
sums received from Debtor, any other guarantor, endorser or cosigner or from the
sale or collection of collateral or its proceeds to any indebtedness whatsoever
in any order and regardless of whether or not such indebtedness is guaranteed
hereby, is secured by collateral or is due and payable, (k) apply any sums
received from Guarantor or from the sale of collateral granted by Guarantor to
any, all, or any portion of the Credit in any order regardless of whether the
Credit is secured by collateral, but only so long as such Credit is due and
payable, and (l) exercise any right or remedy it may have with respect to any
Credit or any collateral securing any Credit, this Agreement or any other
guaranty, including bidding and purchasing at any sale of any such collateral,
and compromising, collecting or otherwise liquidating any collateral or any
Credit.

      6.    (a)   Guarantor acknowledges that Guarantor may have certain rights
under applicable law which, if not waived by Guarantor, might provide Guarantor
with defenses against Guarantor's liability under this Agreement. Among those
rights, are certain rights of subrogation, reimbursement, indemnification and
contribution, and rights provided in sections 2787 to 2855, inclusive, of the
California Civil Code (or any comparable provision of applicable state law). To
the maximum extent permitted by law, Guarantor waives all of Guarantor's rights
of subrogation, reimbursement, indemnification, and contribution, and any other
rights and defenses that are or may become available to Guarantor, whether such
rights arise by reason of any or all of California



                                      -2-
   3

Civil Code Sections 2787 to 2855, inclusive (or any comparable provision of
applicable state law), or otherwise, and including, without limitation,
Guarantor's rights:

                  (i)    To require Lender to notify Guarantor of any default by
Debtor, provide Guarantor with notice of any sale or other disposition of
security for any Credit, or disclose information with respect to the Credit, the
Debtor, or any other guarantor, co-signer or endorser, or with respect to any
collateral;

                  (ii)   That Guarantor's obligation under this Agreement must
be commensurate with that of Debtor;

                  (iii)  To be discharged based upon the absence of any
liability of the Debtor, at any time, by virtue of operation of law, or
otherwise, or due to any other disability or defense of Debtor or any other
guarantor, endorser or co-signer;

                  (iv)   To be discharged if any of the terms, conditions or
provisions of the Credit are altered in any respect;

                  (v)    To be discharged upon acceptance by Lender of anything
in partial satisfaction of the Credit, and/or if Lender designates portion of
the Credit to be satisfied;

                  (vi)   To be discharged upon any modification of the Credit or
the release by Lender of Debtor or any other guarantor, endorser or co-signer,
or if any remedies against any such person are suspended or impaired;

                  (vii)  To require Lender to proceed against Debtor, or any
other guarantor, endorser, co-signer, or other person, or to pursue or refrain
from pursuing any other remedy in Lender's power;

                  (viii) To receive the benefit of or participate in any and all
security for repayment and/or performance of the Credit;

                  (ix)   To have any security for the Credit first applied to
satisfy or discharge the Credit;

                  (x)    That any arbitration award rendered against Debtor not
constitute an award against Guarantor;

                  (xi)   To be discharged based upon any failure by Lender to
perfect or continue perfection of any lien, use due diligence to collect all or
any Credit, or if recovery against Debtor becomes barred by any statute of
limitations, or if Debtor is not liable for any deficiency after Lender realizes
upon any collateral; and



                                      -3-
   4

                  (xii) To be discharged due to the release or discharge of any
collateral for any Credit or guaranty, or relating to the validity, value or
enforceability of any collateral.

            (b)   Without in any way limiting the foregoing, and in addition
thereto, to the maximum extent permitted by law, Guarantor waives: (i) any
defense based upon or arising out of any bankruptcy, insolvency, reorganization,
arrangement, readjustment of debt, liquidation or dissolution proceeding
commenced by or against Debtor 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 Credit (including without limitation any interest
thereon), in or as a result of any such proceeding; (ii) any defense arising by
reason of any disability or other defense of Debtor or any other guarantor or
any endorser, co-maker or other person or by reason of the cessation from any
cause whatsoever of the liability of Debtor or any other guarantor or any
endorser, co-maker or other person with respect to all or any part of the
Credit; (iii) any defense arising as a result of any election by Lender under
Section 1111(b) of Title 11 of the U.S. Code; or (iv) any defense based on any
borrowing or grant of a security interest under Section 364 of Title 11 of the
U.S. Code.

            (c)   Guarantor also waives all rights and defenses that Guarantor
may have because the Debtor's debt is secured by real property. This means,
among other things: (1) Lender may collect from Guarantor without first
foreclosing on any real or personal property collateral pledged by Debtor; and
(2) if Lender forecloses on any real property collateral pledged by the Debtor:
(A) the amount of the debt 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, and (B) Lender may collect from Guarantor even if Lender,
by foreclosing on the real property collateral, has destroyed any right
Guarantor may have to collect from Debtor. This is an unconditional and
irrevocable waiver of any rights and defenses Guarantor may have because
Debtor's debt is secured by real property. These rights and defenses include,
but are not limited to, any rights or defenses directly or indirectly based upon
Section 580a, 580b, 580d, or 726 of the California Code of Civil Procedure (or
any comparable provision of applicable state law).

            (d)   Guarantor also waives all rights and defenses arising out of
an election of remedies by Lender, even though that election of remedies, such
as a nonjudicial foreclosure with respect to security for a guaranteed
obligation, has destroyed Guarantor's rights of subrogation and reimbursement
against the principal by the operation of Section 580d of the California Code of
Civil Procedure (or any comparable provision of applicable state law) or
otherwise.

            (e)   To the maximum extent permitted by law, Guarantor further
waives any and all rights to receive any notice of judicial or nonjudicial sale
or foreclosure of any real or personal property that may be the subject of any
security instruments or that may secure obligations of any other guarantor to
Lender, and Guarantor's failure to receive any such notice shall not impair or
affect Guarantor's liability. Notwithstanding any foreclosure of the lien of any
security instrument given with respect to the Credit or any other guaranty,
whether by the exercise of the power of sale contained therein, by any action
for judicial foreclosure, or by any acceptance of a deed or other transfer in
lieu of foreclosure, whether or not such method of foreclosure or transfer in
lieu of foreclosure was for a consideration equal to or greater than the fair
market value of the security



                                      -4-
   5

property, Guarantor shall remain bound under this Agreement for the Credit and
shall be liable to Lender for any and all of the Credit remaining unpaid after
any such foreclosure.

            (f)   If for any reason Debtor is under no legal obligation to
discharge any of the Credit, or if any of the Credit have become irrecoverable
from Debtor for any reason, this Agreement shall nevertheless be binding on
Guarantor to the same extent as if the Guarantor at all times had been the
primary obligor on all such Credit.

            (g)   In the event (i) Debtor defaults in the payment of any of the
Credit or (ii) acceleration of the time for payment of any of the Credit is
stayed upon the insolvency, bankruptcy or reorganization of the Debtor, or for
any other reason, all such amounts otherwise subject to acceleration under the
agreement evidencing such Credit, shall be immediately due and payable by
Guarantor. Guarantor waives all presentments, demands for performance, notices
of nonperformance, protests, notices of protest, dishonor and acceptance of this
Agreement.

      7.    (a)   Guarantor hereby grants to Foothill, for the benefit of
Lender, a continuing security interest in all of its right, title, and interest
in all currently existing and hereafter acquired or arising Personal Property
Collateral in order to secure prompt payment and performance of any and all of
Guarantor's obligations to Lender under this Agreement. Foothill's Liens in and
to the Personal Property Collateral shall attach to all Personal Property
Collateral without further act on the part of Lender or any Guarantor. Anything
contained in this Agreement or any other Loan Document to the contrary
notwithstanding, except for Permitted Dispositions, Guarantor has no authority,
express or implied, to dispose of any item or portion of the Personal Property
Collateral.

            (b)   In the event that any Personal Property Collateral of
Guarantor, including proceeds, is evidenced by or consists of Negotiable
Collateral, and if and to the extent that perfection or priority of Foothill's
security interest is dependent on or enhanced by possession, Guarantor,
immediately upon the request of Foothill, shall endorse and deliver physical
possession of such Negotiable Collateral to Foothill, together with any
endorsement thereof or thereon as Foothill determines to be necessary or
appropriate in order to perfect and enforce its Liens.

            (c)   At any time after the occurrence and during the continuation
of an Event of Default, Foothill or Foothill's designee may (a) notify Account
Debtors of Guarantor that the Accounts, chattel paper, or General Intangibles of
Guarantor have been assigned to Foothill or that Foothill has a security
interest therein, or (b) collect such Accounts, chattel paper, or General
Intangibles directly and charge the collection costs and expenses to the Loan
Account. Guarantor agrees that at any time after and during the continuation of
an Event of Default, that it will hold in trust for Lender, as Lender's trustee,
any and all Collections that it receives and immediately will deliver said
Collections to Foothill in their original form as received by such Guarantor.

            (d)   At any time upon the request of Foothill, Guarantor shall
execute and deliver to Foothill, any and all financing statements, original
financing statements in lieu of continuation statements, fixture filings,
security agreements, pledges, assignments, endorsements



                                      -5-
   6

of certificates of title, and all other documents (the "Additional Documents")
that Foothill may request in its Permitted Discretion, in form and substance
reasonably satisfactory to Foothill, to perfect and continue perfected or better
perfect the Foothill's Liens in the Personal Property Collateral (whether now
owned or hereafter arising or acquired), to create and perfect Liens in favor of
Foothill in any Real Property acquired after the Closing Date, and in order to
fully consummate all of the transactions contemplated hereby and under the other
Loan Documents. To the maximum extent permitted by applicable law, Guarantor
authorizes Foothill to execute any such Additional Documents in Guarantor's name
and authorizes Foothill to file such executed Additional Documents in any
appropriate filing office. In addition, but subject to Guarantor's rights not to
pursue or to abandon certain patents and trademarks as provided in subsections
1(b) and 1(c) of the Intellectual Property Security Agreement, on such periodic
basis as Foothill shall require, Guarantor shall (i) provide Foothill with a
report of all new patentable, copyrightable, or trademarkable materials acquired
or generated by Guarantor during the prior period, (ii) cause all patents,
copyrights, and trademarks acquired or generated by Guarantor that are not
already the subject of a registration with the appropriate filing office (or an
application therefor diligently prosecuted) to be registered with such
appropriate filing office in a manner sufficient to impart constructive notice
of Guarantor's ownership thereof, and (iii) cause to be prepared, executed, and
delivered to Foothill supplemental amendments and schedules to the applicable
Loan Documents to identify such patents, copyrights, and trademarks as being
subject to the security interests created thereunder.

            (e)   Guarantor hereby irrevocably makes, constitutes, and appoints
Foothill (and any of Foothill's officers, employees, or agents designated by
Foothill) as Guarantor's true and lawful attorney, with power to (i) if
Guarantor refuses to, or fails timely to execute and deliver any of the
documents described in paragraph 7(d), sign the name of Guarantor on any of the
documents described in paragraph 7(d), (ii) at any time that an Event of Default
has occurred and is continuing, sign Guarantor's name on any invoice or bill of
lading relating to Guarantor's Personal Property Collateral, drafts against
Account Debtors, or notices to Account Debtors, (iii) at any time that an Event
of Default has occurred and is continuing, send requests for verification of
Guarantor's Accounts, (iv) endorse Guarantor's name on any Collection item that
may come into Lender's possession, (v) at any time that an Event of Default has
occurred and is continuing, make, settle, and adjust all claims under
Guarantor's policies of insurance and make all determinations and decisions with
respect to such policies of insurance, and (vi) at any time that an Event of
Default has occurred and is continuing, settle and adjust disputes and claims
respecting Guarantor's Accounts, chattel paper, or General Intangibles directly
with Account Debtors, for amounts and upon terms that Foothill determines to be
reasonable, and Foothill may cause to be executed and delivered any documents
and releases that Foothill determines to be necessary. The appointment of
Foothill as Guarantor's attorney, and each and every one of its rights and
powers, being coupled with an interest, is irrevocable until all of the Credit
has been fully and finally repaid and performed and Lender's obligations to
extend credit to Debtor are terminated.

            (f)   Subject to such limitations as are set forth in the Loan
Agreement, Lender (through any of their respective officers, employees, or
agents) shall have the right, from time to time hereafter to inspect Guarantor's
Books and to check, test, and appraise the Personal Property



                                      -6-
   7

Collateral in order to verify Guarantor's financial condition or the amount,
quality, value, condition of, or any other matter relating to, the Personal
Property Collateral.

            (g)   Guarantor agrees that it will not transfer assets out of any
Securities Accounts of Guarantor other than as permitted under Section 7.19 of
the Loan Agreement and, if to another securities intermediary, unless the
applicable Guarantor, Foothill, and the substitute securities intermediary have
entered into a Control Agreement. No arrangement contemplated hereby or by any
Control Agreement in respect of any Securities Accounts or other Investment
Property of Guarantor shall be modified by any Guarantor without the prior
written consent of Foothill. Upon the occurrence and during the continuance of a
Default or Event of Default, Foothill may notify any securities intermediary to
liquidate the applicable Securities Account or any related Investment Property
maintained or held thereby and remit the proceeds thereof to Agent's Account.

      8.    (a)   Guarantor waives demand, protest, notice of protest, notice of
default or dishonor, notice of payment and nonpayment, nonpayment at maturity,
release, compromise, settlement, extension, or renewal of documents,
instruments, chattel paper, and guarantees at any time held by Lender on which
Guarantor may in any way be liable.

            (b)   Guarantor hereby agrees that: (i) so long as Foothill complies
with its obligations, if any, under the Code, Lender shall not in any way or
manner be liable or responsible for: (A) the safekeeping of the Personal
Property Collateral, (B) any loss or damage thereto occurring or arising in any
manner or fashion from any cause, (C) any diminution in the value thereof, or
(D) any act or default of any carrier, warehouseman, bailee, forwarding agency,
or other Person, and (ii) all risk of loss, damage, or destruction of the
Personal Property Collateral shall be borne by Guarantor.

      9.    Guarantor represents and warrants to Lender that: (a) Lender has
made no representation to Guarantor in regard to Debtor, the Credit or any
matters pertaining thereto, upon which Guarantor is relying in giving this
Agreement; and (b) Guarantor has established adequate means and assumes the
responsibility for being and keeping informed of the financial condition of the
Debtor and of all other circumstances bearing upon the risk of nonpayment of the
debt which diligent inquiry would reveal and Lender shall have no duty to advise
Guarantor of information known to it regarding such condition or any such
circumstance.

      10.   In addition to all liens upon and rights of setoff against the
money, securities or other property of Guarantor given to Lender by law or
otherwise as security for this Agreement, Guarantor hereby pledges to Lender and
grants Lender a security interest in, and Lender shall have a right of setoff
against, all money, securities and other property of Guarantor now or hereafter
in the possession of or on deposit with Lender, whether held in general or
special account or deposit or for safekeeping or otherwise; and each such
security interest or right of setoff may be exercised without demand upon, or
notice to, Guarantor. No action or lack of action by Lender with respect to any
security interest or right of setoff or otherwise shall be deemed a waiver
thereof, and every right of setoff or security interest or otherwise shall
continue



                                      -7-
   8

in full force and effect until specifically released by Lender in writing. The
security interests created hereby shall secure all Guarantor's obligations to
Lender under this Agreement, any subsequent guaranty executed by Guarantor and
any other Loan Documents to which Guarantor is a party.

      11.   Any and all indebtedness of Debtor now or hereafter owed to
Guarantor and all claims whenever arising of Guarantor against Debtor are hereby
subordinated to the Credit and assigned to Lender as additional collateral. If
Lender so requests, any note or other instrument evidencing such indebtedness
and all claims of Guarantor against Debtor shall be delivered to Lender, and
such indebtedness and all claims of Guarantor against Debtor shall be collected,
enforced and received by Guarantor as trustee for Lender and be paid over to
Lender on account of the Credit but without reducing or affecting in any manner
the liability of Guarantor hereunder. Should Guarantor fail to collect proceeds
of debt owed to it by Debtor and pay the proceeds to Lender, Lender as
Guarantor's attorney-in-fact may do such acts and sign such documents in
Guarantor's name as Lender considers necessary, at its discretion, to effect
such collection, and Guarantor hereby irrevocably appoints Lender as Guarantor's
attorney-in-fact for such purposes. If Debtor is a corporation, partnership, or
limited liability company, Guarantor will not withdraw or accept without
Lender's prior written consent any return of any capital invested or equity
interest in Debtor.

      12.   Guarantor agrees that to the extent Debtor makes a payment or
payments or is credited for any payment or payments made for the account of or
on behalf of Debtor to Lender, which payment or payments, or any part thereof,
is subsequently invalidated, determined to be fraudulent or preferential,
voided, set aside and/or required to be repaid to any trustee, receiver,
assignee or any other party whether under any bankruptcy, state or federal law,
common law or equitable cause or otherwise, then to the extent thereof, the
obligation or part thereof intended to be satisfied thereby, together with the
guaranty thereof hereunder, shall be revived, reinstated and continued in full
force and effect as if said payment or payments had not originally been made by
or for the account of or on behalf of Debtor.

      13.   Guarantor agrees that to the extent Guarantor makes a payment or
payments or is credited for any payment or payments made for the account of or
on behalf of Guarantor to Lender, which payment or payments, or any part
thereof, is subsequently invalidated, determined to be fraudulent or
preferential, voided, set aside and/or required to be repaid to any trustee,
receiver, assignee or any other party whether under any bankruptcy, state or
federal law, common law or equitable cause or otherwise, then to the extent
thereof, the obligation or part thereof intended to be satisfied thereby, shall
be revived, reinstated and continued in full force and effect as if said payment
or payments had not originally been made by or for the account of or on behalf
of Guarantor.

      14.   Guarantor's obligations hereunder are not contingent upon and are
independent of the obligations of Debtor, or any other guarantor or surety of
the Credit. This Agreement is not made in consideration of the liability of any
other guarantor or surety of the Credit. The release or death of any guarantor
of the Credit or the revocation of this Agreement or any other guaranty



                                      -8-
   9

shall not release or otherwise affect the liability of any other non-revoking
guarantor. A separate action or actions may be brought and prosecuted against
Guarantor whether action is brought against Debtor or any other guarantor or
whether Debtor or any other guarantor be joined in any such action or actions.
To the maximum extent permitted by law, Guarantor specifically waives the
benefit of the statute of limitations affecting its liability hereunder or the
enforcement hereof, or the collection of any Credit. Any partial payment by
Debtor which operates to toll any statute of limitation as to Debtor shall
likewise toll the statute of limitations as to Guarantor.

      15.   Should any one or more provisions of this Agreement be determined to
be illegal or unenforceable, all other provisions shall remain effective. In the
event of any inconsistency between the terms of this Agreement and those of the
Loan Agreement, the terms of the Loan Agreement shall control.

      16.   Lender may, with or without notice, assign this Agreement in whole
or in part, provided, however, that any such assignment shall be in connection
with a permitted assignment of Lender's respective rights and obligations under
the Loan Agreement. This Agreement shall inure to the benefit of Lender, its
successors and assigns, and shall bind Guarantor and Guarantor's successors and
assigns; provided, however, that nothing herein shall be understood to mean that
Guarantor may assign this Agreement or any rights or duties hereunder without
Foothill's prior written consent.

      17.   Guarantor agrees to pay Lender on demand reasonable and documented
out-of-pocket attorneys' fees and all other reasonable and documented
out-of-pocket costs and expenses which may be incurred in the collection or
attempted collection from Debtor of any Credit and in the enforcement or
attempted enforcement by Lender of this Agreement or any collateral therefor,
whether or not legal proceedings or suit are instituted, together with interest
thereon at the rate applicable to the Credit and including, without limitation,
all reasonable and documented out-of-pocket attorneys' fees and related costs of
enforcement of any and all judgments and awards and upon any appeal relating
thereto.

      18.   Guarantor warrants and represents to Lender that:

            (a)   All financial statements and other financial information
furnished or to be furnished to Lender are or will be true and correct and do
and will fairly represent the financial condition of Guarantor (including all
contingent liabilities) as of the dates thereof; and

            (b)   There has been no material adverse change in Guarantor's
financial condition since the dates of the financial statements and other
information furnished to Lender, except as previously disclosed to Lender in
writing.



      19.   (a)   Upon the occurrence, and during the continuation, of an Event
of Default, the Required Lenders (at their election but without notice of their
election and without demand) may authorize and instruct Foothill to do any one
or more of the following on behalf of Lender



                                      -9-
   10

(and Foothill, acting upon the instructions of the Required Lenders, shall do
the same on behalf of Lender), all of which are authorized by Guarantor:

                  (i)   Declare the Credit (including, without limitation any

purporting to act in its behalf, and any Credit granted in reliance upon the
purported exercise of such power or authority is guaranteed hereunder.

      22.   Receipt of a true copy of this Agreement is hereby acknowledged by
each Guarantor. Guarantor understands and agrees that Lender's acceptance of
this Agreement shall not constitute a commitment of any nature whatsoever by
Lender to extend, renew or hereafter extend Credit to Debtor. Guarantor agrees
that this Agreement shall be effective with or without notice from Lender of its
acceptance of the Agreement.

      23.   If Guarantor has executed more than one guaranty of the indebtedness

be cumulative, and a subsequent guaranty executed by Guarantor shall not
supersede or replace this Agreement.

      24.   GUARANTOR WAIVES ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION OR

INDIRECTLY TO THIS AGREEMENT, THE CREDIT, THE COLLATERAL THEREFOR OR ANY MATTER

      27.   All rights, remedies, powers and benefits granted to Lender under
this Agreement, the Credit, any oral or other written agreement or applicable
law whether expressly granted or implied in law or otherwise, are cumulative and
not exclusive, and are enforceable alternatively, successively, or concurrently
on any one or more occasions at Lender's discretion.

      28.   Lender shall not, by any act, delay, omission or otherwise be deemed
to have expressly or impliedly waived any security interest granted to Lender
hereunder or Lender's rights, powers and/or remedies hereunder (including any
right of setoff) unless such waiver shall be in writing and signed by an
authorized officer of Lender. Any such waiver shall be enforceable only to the
extent specifically set forth therein. A waiver by Lender of any default, right,
power and/or remedy on any one occasion shall not be construed as a bar to or
waiver of any such default, right, power and/or remedy which Lender would
otherwise have on any future occasion whether similar in kind or otherwise. Any
failure by Lender to file or enforce a claim against the estate (whether in
administration, bankruptcy, probate or other proceeding) of Debtor or of any
others, shall not affect Guarantor's liability hereunder.

Guarantor is a party, constitutes the entire agreement between the parties with
respect to the subject matter of the Agreement and supersedes any and all
previous or contemporaneous correspondence, statements, or agreements by or
between the parties hereto with respect to the subject matter. This Agreement
may be modified only by a written instrument signed by the parties hereto.
Neither this Agreement or any related agreement, document or instrument nor any
provision hereof or thereof shall be amended, modified or discharged orally or
by course of conduct, but only by a written agreement signed by an authorized
officer of Lender expressly referring to this Agreement and to the provisions so
amended, modified or discharged.

      30.   Lender's books and records showing the account(s) between Lender and
Debtor shall be admissible in evidence in any action or proceeding as prima
facie proof of the items set forth therein. Lender's statements rendered to
Debtor, to the extent to which no objection is made within thirty (30) days
after date thereof, shall be deemed conclusively correct and constitute an
account stated, which shall be binding on Guarantor whether or not Guarantor
receives a copy of any such statement or notice thereof.

      31.   This is a continuing guaranty of the Credit, including those arising
after any repayment and reborrowing and under any successive and future
transactions which may increase, renew or continue the original Credit. To the
maximum extent permitted by law, Guarantor waives all rights to revoke this
Agreement, whether under California Civil Code Section 2815 (or similar state
law) or otherwise. If at any time under applicable law, the foregoing waiver by
Guarantor is not valid or enforceable to any extent, then the remaining portion
of this paragraph is applicable. Revocation of this Agreement, if required to be
permitted by applicable law, shall be effective only after written notice
thereof is received by an officer of Lender by certified or registered mail,
return receipt requested at its address set forth in Section 12 of the Loan
Agreement, or at any other office of Lender designated in a written notice
mailed by Lender to Guarantor at its address set forth below. Any such
revocation shall be effective only as to the



                                      -13-
   14

revoking party and shall not affect that party's obligations with respect to
Credit existing before the revocation becomes effective or as to any renewals,
extensions or modifications of any such Credit, whether such renewal, extension
or modification is made prior to or after revocation, including those evidenced
by a new or additional instrument or agreement or which change the rate of
interest on any Credit, or for post-revocation interest and collection expenses
accruing or incurred by Lender with respect thereto. Notwithstanding any
revocation hereof, this Agreement shall not be terminated until Lender has
received indefeasible payment in full of all Credit which is guaranteed hereby.
Credit existing before revocation becomes effective shall be deemed to include,
without limitation, all Credit or advances which Lender has committed to make to
Debtor in reliance upon this Agreement, even though the amount of such Credit or
advances has not been advanced as of the effective date of revocation, and even
though Lender may have defenses or defaults which would relieve it of such
commitment, if asserted.

      32.   The provisions of this Agreement shall be construed and interpreted
and all rights and obligations hereunder determined in accordance with the laws
of the State of New York.

      33.   GUARANTOR ACKNOWLEDGES THAT LENDER HAS OR MAY IN THE FUTURE EXTEND

ANY AND ALL CREDIT AND LENDER IS RELYING ON THE WAIVERS, WARRANTIES AND PROMISES
MADE BY GUARANTOR IN THIS AGREEMENT. GUARANTOR AGREES THAT EACH OF THE WAIVERS,
WARRANTIES AND PROMISES SET FORTH IN THIS AGREEMENT ARE MADE WITH GUARANTOR'S
UNDERSTANDING OF THEIR SIGNIFICANCE AND CONSEQUENCES AND THAT THEY ARE
REASONABLE. IF ANY WAIVERS, WARRANTIES AND PROMISES ARE DETERMINED TO BE
CONTRARY TO ANY APPLICABLE LAW OR PUBLIC POLICY, SUCH WAIVERS, WARRANTIES AND
PROMISES SHALL BE EFFECTIVE TO THE MAXIMUM EXTENT PERMITTED BY LAW. BEFORE
SIGNING THE AGREEMENT, GUARANTOR HAS EITHER SOUGHT THE ADVICE OF COUNSEL TO
EXPLAIN THE WAIVERS OF ITS RIGHTS AND DEFENSES AS STATED HEREIN AND THE EFFECT
THEREOF, OR HAS HAD THE OPPORTUNITY TO SEEK SUCH COUNSEL, AND IN ANY EVENT,
INTENDS THIS AGREEMENT TO BE AS UNRESTRICTED AS POSSIBLE. GUARANTOR HAS
THEREFORE CONSCIOUSLY AND INTENTIONALLY WAIVED ALL DEFENSES OF GUARANTOR AND
RIGHTS WHICH COULD EXONERATE GUARANTOR HEREUNDER TO THE FULL EXTENT PERMITTED BY
THE LAW OF THE STATE OF NEW YORK, WHETHER OR NOT EACH AND EVERY DEFENSE, RIGHT
OR WAIVER IS EXPLAINED OR DESCRIBED IN DETAIL IN THIS AGREEMENT.

      34.   GUARANTOR ACKNOWLEDGES THAT NEITHER LENDER NOR ANY OF LENDER'S
OFFICERS OR EMPLOYEES HAS MADE ANY PROMISE OR REPRESENTATION, NOT INCORPORATED
HEREIN, WHETHER ORAL, WRITTEN OR IMPLIED, TO CAUSE GUARANTOR TO SIGN THIS
AGREEMENT. GUARANTOR IS NOT SIGNING THIS AGREEMENT IN RELIANCE ON ANY PROMISE,
CONDITION OR THE OCCURRENCE OF ANY EVENT, AND THERE ARE NO ORAL UNDERSTANDINGS,
STATEMENTS OR AGREEMENTS WHICH HAVE NOT BEEN INCLUDED IN THIS



                                      -14-
   15

AGREEMENT. GUARANTOR UNDERSTANDS THAT LENDER HAS THE RIGHT TO ENFORCE PAYMENT OF
THE CREDIT AGAINST DEBTOR OR GUARANTOR IN ANY ORDER AND LENDER IS NOT OBLIGATED
TO OBTAIN ANY OTHER OR ADDITIONAL GUARANTORS OF THE CREDIT OR TO TAKE ANY OTHER
COURSE OF ACTION.
