     ($45,000,000.00) according to the terms of that Revolving Promissory Note
     dated July 25, 1997, made by Continental Circuits Corp., a Delaware

         Party, whether such amounts are due and payable on the date (s)
         scheduled therefor, on the occurrence of an Early Termination Date (as
         defined in the Master Agreement), or otherwise.

All of the indebtedness and obligations secured by this Agreement are
hereinafter collectively called the "Obligation."

3.    USE; LOCATION; CONSTRUCTION

      3.1 The Collateral is or will be used or produced primarily for business
purposes.

      3.2 The Collateral will be kept at Debtor's address set forth at the
beginning of this Agreement and/or at the following location(s): 15508 Bratton
Lane, Austin, Texas 78728.

      3.3 Debtor's records concerning the Collateral will be kept at Debtor's
address set forth at the beginning of this Agreement.

4.    REPRESENTATIONS AND WARRANTIES OF DEBTOR

      Debtor hereby represents and warrants that:

      4.1 The execution, delivery and performance by Debtor of this Agreement
and all other documents and instruments relating to the Obligation will not
result in a Material Adverse Effect due to any breach of the terms and
conditions or due to a default under any agreement or instrument under which
Debtor is a party or is obligated. Debtor is not in default in the performance
or observance of any covenants, conditions or provisions of any such agreement
or instrument that would result in a Material Adverse Effect.

      4.2 Except as otherwise consented to by Secured Party in writing and
except for any Permitted Liens, Debtor is the owner of the Collateral free of
all security interests or other encumbrances except the Security Interest and no
financing statement covering the Collateral is


                                      2
<PAGE>   3
filed or recorded in any public office.

      4.3 The Collateral is, and is intended to be, used, produced or acquired
by Debtor for use primarily for the purpose marked in Section 3 above. The
address of Debtor set forth at the beginning of this Agreement is the chief
executive office of Debtor.

      4.4 Each account, chattel paper or general intangible included in the
Collateral is genuine and enforceable in accordance with its terms against the
party named therein who is obligated to pay the same (hereinafter called
"Obligor"), and the security interests that are part of each item of chattel
paper included in the Collateral are valid, first and prior perfected security
interests. To the best of Debtor's knowledge, each Obligor is solvent, and the
amount that Debtor has represented to Secured Party as owing by each Obligor is
the amount actually and unconditionally owing by that Obligor, without deduction
except for normal cash discounts where applicable; to the best of Debtor's
knowledge, no Obligor has any defense, setoff, claim or counterclaim against
Debtor that can be asserted against Secured Party whether in any proceeding to
enforce the Security Interest or otherwise. Each document, instrument and
chattel paper included in the Collateral is complete and regular on its face and
free from evidence of forgery or alteration. No default has occurred in
connection with any instrument, document or chattel paper included in the
Collateral, no payment in connection therewith is overdue and no presentment,
dishonor or protest has occurred in connection therewith.

of Secured Party and, except as otherwise consented to by Secured Party in
writing, shall keep the Collateral free of all security interests or other
encumbrances except the Security Interest. Although proceeds of Collateral are
covered by this Agreement, this shall not be construed to mean that Secured
Party consents to any sale of the Collateral.

      5.2 Debtor shall keep and maintain the Collateral in good condition and
repair and shall not use the Collateral in violation of any provision of this
Agreement or any applicable statute, ordinance or regulation or any policy of

<PAGE>   4
becoming a fixture and shall prevent any portion of the Collateral from being or
becoming an accession to other goods that are not part of the Collateral.

      5.6 If the Collateral includes motor vehicles, Debtor shall not remove or
permit such motor vehicles to be removed from the State of Arizona without the

registered with and licensed by the State of Arizona, shall provide Secured
Party with the license numbers of all titled vehicles, and upon the occurrence
of an Event of Default and notice thereof to Debtor by Secured Party, shall
cause the Security Interest to be shown as a valid first lien on the Certificate
of Title for all titled vehicles and shall thereupon deliver lien filing
receipts to Secured Party as evidence thereof.

      5.7 Debtor, upon demand, shall promptly deliver to Secured Party all
instruments, documents and chattel paper included in the Collateral and all
invoices, shipping or delivery records, purchase orders, contracts or other
items related to the Collateral. Debtor shall notify Secured Party immediately

with respect to any Collateral. Debtor, without Secured Party's prior written
consent, shall not make or agree to make any alteration, modification or
cancellation of, or substitution for, or credit, adjustment or allowance on, any
Collateral, except in the ordinary course of business.

      5.8 Debtor shall give Secured Party immediate written notice of any change
in the location of: (i) Debtor's chief executive office; (ii) the Collateral or
any part thereof; or (iii) Debtor's records concerning the Collateral.

      5.9 Secured Party or its agents may inspect the Collateral at reasonable
times and may enter into any premises where the Collateral is or may be located.
Debtor shall keep records concerning the Collateral in accordance with generally
accepted accounting principles and, if required in writing by Secured Party,
shall mark its records and the Collateral to indicate the Security Interest.
Secured Party shall have free and complete access to Debtor's records and shall
have the right to make extracts therefrom or copies thereof. Upon request of
Secured Party from time to time, Debtor shall submit up-to-date schedules of the
items comprising the Collateral in such detail as Secured Party may require and
shall deliver to Secured Party confirming specific assignments of all accounts,
instruments, documents and chattel paper included in the Collateral.

      5.10 Except for Permitted Liens, Debtor, at its cost and expense, shall
protect and defend this Agreement, all of the rights of Secured Party hereunder,
and the Collateral against all claims and demands of other parties, including
without limitation defenses, setoffs, claims and counterclaims asserted by any
Obligor against Debtor and/or Secured Party. Except for Permitted Liens, Debtor
shall pay all claims and charges that in the reasonable opinion of Secured Party
might prejudice, imperil or otherwise affect the Collateral or the Security
Interest. Except for Permitted Liens, Debtor shall promptly notify Secured Party
of any levy, distraint or other seizure by legal process or otherwise of any
part of the Collateral and of any threatened or filed claims or proceedings that
might in any way affect or impair the terms of this Agreement.



                                      4
<PAGE>   5
      5.11 The Security Interest, at all times, shall be perfected and shall be
prior to any other interests in the Collateral except for Permitted Liens.
Debtor shall act and perform as necessary and shall execute and file all
security agreements, financing statements, continuation statements and other
documents requested by Secured Party to establish, maintain and continue the
perfected Security Interest. Debtor, on demand, shall promptly pay all costs and
expenses of filing and recording, including the costs of any searches, deemed
reasonably necessary by Secured Party from time to time to establish and
determine the validity and the continuing priority of the Security Interest.

      5.12 If Debtor shall fail to pay any taxes, assessments, expenses or
charges, to keep all of the Collateral free from other security interests,
encumbrances or claims, to keep the Collateral in good condition and repair, to
procure and maintain insurance thereon, or to perform otherwise as required
herein, Secured Party may advance the monies necessary to pay the same, to
accomplish such repairs, to procure and maintain such insurance or to so
perform; Secured Party is hereby authorized to enter upon any property in the
possession or control of Debtor for such purposes.

      5.13 All rights, powers and remedies granted Secured Party herein, or
otherwise available to Secured Party, are for the sole benefit and protection of
Secured Party, and Secured Party may exercise any such right, power or remedy at
its option and in its sole and absolute discretion without any obligation to do
so. In addition, if under the terms hereof, Secured Party is given two or more
alternative courses of action, Secured Party may elect any alternative or
combination of alternatives at its option and in its sole and absolute
discretion. All monies advanced by Secured Party under the terms hereof and all
amounts paid, suffered or incurred by Secured Party in exercising any authority
granted herein, including reasonable attorneys' fees, shall be added to the
Obligation, shall be secured by the Security Interest, shall bear interest at
the highest rate payable on any of the Obligation until paid, and shall be due
and payable by Debtor to Secured Party immediately without demand.

6.   NOTIFICATION AND PAYMENTS; COLLECTION OF COLLATERAL; USE OF
     COLLATERAL BY DEBTOR

      6.1 Secured Party, after the occurrence of any Event of Default, defined
below, may notify any or all Obligors of the existence of the Security Interest
and may direct the Obligors to make all payments on the Collateral to Secured
Party. Secured Party agrees to notify Debtor promptly after any such action,
provided that the failure to give such notice shall not affect the validity of
such action. Until Secured Party has notified the Obligors to remit payments
directly to it, Debtor, at Debtor's own cost and expense, shall collect or cause
to be collected the accounts and monies due under the accounts, documents,
instruments and general intangibles or pursuant to the terms of the chattel
paper. Secured Party shall not be liable or responsible for any embezzlement,
conversion, negligence or default by Debtor or Debtor's agents with respect to
such collections; all agents used in such collections shall be agents of Debtor
and not agents of Secured Party. Unless Secured Party notifies Debtor in writing
that it waives one or more of the


                                      5
<PAGE>   6
requirements set forth in this sentence, any payments or other proceeds of
Collateral received by Debtor, before or after notification to Obligors, shall
be held by Debtor in trust for Secured Party in the same form in which received,
shall not be commingled with any assets of Debtor and shall be turned over to
Secured Party not later than the next business day following the day of receipt.
All payments and other proceeds of Collateral received by Secured Party directly
or from Debtor shall be applied to the Obligation in such order and manner and
at such time as Secured Party, in its sole discretion, shall determine. In
addition, Debtor shall promptly notify Secured Party of the return to or
possession by Debtor of goods underlying any Collateral; Debtor shall hold the
same in trust for Secured Party and shall dispose of the same as Secured Party
directs.

      6.2 Secured Party, after the occurrence of an Event of Default may demand,
collect and sue on the Collateral (either in Debtor's or Secured Party's name),
enforce, compromise, settle or discharge the Collateral and endorse Debtor's
name on any instruments, documents, or chattel paper included in or pertaining
to the Collateral; Secured Party agrees to notify Debtor promptly after any such
action, provided that the failure to give such notice shall not affect the
validity of such action. Debtor hereby irrevocably appoints Secured Party its
attorney in fact for all such purposes.

      6.3 Until the occurrence of an Event of Default, Debtor may: (i) use,
consume and sell any inventory included in the Collateral in any lawful manner
in the ordinary course of Debtor's business provided that all sales shall be at
commercially reasonable prices; and (ii) subject to Paragraphs 6.1 and 6.2
above, retain possession of any other Collateral and use it in any lawful manner
consistent with this Agreement.

7.    COLLATERAL IN THE POSSESSION OF SECURED PARTY

      7.1 Secured Party shall use such reasonable care in handling, preserving
and protecting the Collateral in its possession as it uses in handling similar
property for its own account. Secured Party, however, shall have no liability
for the loss, destruction or disappearance of any Collateral unless there is
affirmative proof of a lack of due care; the lack of due care shall not be
implied solely by virtue of any loss, destruction or disappearance.

      7.2 Debtor shall be solely responsible for taking any and all actions to
preserve rights against all Obligors; Secured Party shall not be obligated to
take any such actions whether or not the Collateral is in Secured Party's
possession. Debtor waives presentment and protest with respect to any instrument
included in the Collateral on which Debtor is in any way liable and waives
notice of any action taken by Secured Party with respect to any instrument,
document or chattel paper included in any Collateral that is in the possession
of Secured Party.

8.    EVENTS OF DEFAULT; REMEDIES

      8.1 The occurrence of any Event of Default under the Loan Agreement shall
constitute and is hereby defined to be an "Event of Default".

      8.2 Upon the occurrence of any Event of Default and at any time while such
Event of Default is continuing, Secured Party shall have the following rights
and remedies and may do one or more of the following:

      (a) Declare all or any part of the Obligation to be immediately due and
     payable, and the same, with all costs and charges, shall be collectible
     thereupon by action at law.

      (b) Without further notice or demand and without legal process, take
     possession of the Collateral wherever found and, for this purpose, enter
     upon any property occupied by or in the control of Debtor. Debtor, upon
     demand by Secured Party, shall assemble the Collateral and deliver it to
     Secured Party or to a place designated by Secured Party that is reasonably
     convenient to both parties.

      (c) Operate the business of Debtor as a going concern, including, without
     limitation, extend sales or services to new customers and advance funds for
     such operation. Secured Party shall not be liable for any depreciation,
     loss, damage or injury to the Collateral or other property of Debtor as a
     result of such action. Debtor hereby waives any claim of trespass or
     replevin arising as a result of such action.

      (d) Pursue any legal or equitable remedy available to collect the
     Obligation, to enforce its title in and right to possession of the
     Collateral and to enforce any and all other rights or remedies available to
     it.

      (e) Upon obtaining possession of the Collateral or any part thereof, after
     notice to Debtor as provided in Paragraph 8.4 herein, sell such Collateral
     at public or private sale either with or without having such Collateral at
     the place of sale. The proceeds of such sale, after deducting therefrom all
     expenses of Secured Party in taking, storing, repairing and selling the
     Collateral (including reasonable attorneys' fees) shall be applied to the
     payment of the Obligation, and any surplus thereafter remaining shall be
     paid to Debtor or any other person that may be legally entitled thereto. In
     the event of a deficiency between such net proceeds from the sale of the
     Collateral and the total amount of the Obligation, Debtor, upon demand,
     shall promptly pay the amount of such deficiency to Secured Party.

      8.3 Secured Party, so far as may be lawful, may purchase all or any part
of the Collateral offered at any public or private sale made in the enforcement
of Secured Party's rights and remedies hereunder.


                                      7
<PAGE>   8
      8.4 Any demand or notice of sale, disposition or other intended action
hereunder or in connection herewith, whether required by the Uniform Commercial
Code or otherwise, shall be deemed to be commercially reasonable and effective
if such demand or notice is given to Debtor at least fifteen (15) days prior to
such sale, disposition or other intended action, in the manner provided herein
for the giving of notices.

      8.5 Debtor shall pay all costs and expenses, including without limitation
costs of Uniform Commercial Code searches, court costs and reasonable attorneys'
fees, incurred by Secured Party in enforcing payment and performance of the
Obligation or in exercising the rights and remedies of Secured Party hereunder.
All such costs and expenses shall be secured by this Agreement and by all deeds
of trust and other lien and security documents securing the Obligation. In the
event of any court proceedings, court costs and attorneys' fees shall be set by
the court and not by jury and shall be included in any judgment obtained by
Secured Party.

      8.6 In addition to any remedies provided herein for an Event of Default,
Secured Party shall have all the rights and remedies afforded a secured party
under the Uniform Commercial Code and all other legal and equitable remedies
allowed under applicable law. No failure on the part of Secured Party to
exercise any of its rights hereunder arising upon any Event of Default shall be
construed to prejudice its rights upon the occurrence of any other or subsequent
Event of Default. No delay on the part of Secured Party in exercising any such
rights shall be construed to preclude it from the exercise thereof at any time
while that Event of Default is continuing. Secured Party may enforce any one or
more rights or remedies hereunder successively or concurrently. By accepting
payment or performance of any of the Obligation after its due date, Secured
Party shall not thereby waive the agreement contained herein that time is of the
essence, nor shall Secured Party waive either its right to require prompt
payment or performance when due of the remainder of the Obligation or its right
to consider the failure to so pay or perform an Event of Default.

9.    MISCELLANEOUS PROVISIONS

      9.1 The acceptance of this Agreement by Secured Party shall not be
considered a waiver of or in any way to affect or impair any other security that
Secured Party may have, acquire simultaneously herewith, or hereafter acquire
for the payment or performance of the Obligation, nor shall the taking by
Secured Party at any time of any such additional security be construed as a
waiver of or in any way to affect or impair the Security Interest; Secured Party
may resort, for the payment or performance of the Obligation, to its several
securities therefor in such order and manner as it may determine.

      9.2 Without notice or demand, without affecting the obligations of Debtor
hereunder or the personal liability of any person for payment or performance of
the Obligation, and without affecting the Security Interest or the priority
thereof, Secured Party, from time to time, may: (i) extend the time for payment
of all or any part of the Obligation, accept a renewal note therefor, reduce the
payments thereon, release any person liable for all or any part thereof, or
otherwise


                                      8
<PAGE>   9
change the terms of all or any part of the Obligation; (ii) take and hold other
security for the payment or performance of the Obligation and enforce, exchange,
substitute, subordinate, waive or release any such security; (iii) join in any
extension or subordination agreement; or (iv) release any part of the Collateral
from the Security Interest.

      9.3 Except as otherwise provided in the Loan Documents, Debtor waives and
agrees not to assert: (i) any right to require Secured Party to proceed against
any guarantor, to proceed against or exhaust any other security for the
Obligation, to pursue any other remedy available to Secured Party, or to pursue
any remedy in any particular order or manner; (ii) the benefits of any legal or
equitable doctrine or principle of marshalling; (iii) the benefits of any
statute of limitations affecting the enforcement hereof; (iv) demand, diligence,
presentment for payment, protest and demand, and notice of extension, dishonor,
protest, demand and nonpayment, relating to the Obligation; and (v) any benefit
of, and any right to participate in, any other security now or hereafter held by
Secured Party.

      9.4 The terms herein shall have the meanings in and be construed under the
Uniform Commercial Code. Undefined capitalized terms used herein shall have the
meaning given them in the Loan Agreement. This Agreement shall be governed by
and construed according to the laws of the State of Arizona. Each provision of
this Agreement shall be interpreted in such manner as to be effective and valid
under applicable law, but if any provision of this Agreement is held to be void
or invalid, the same shall not affect the remainder hereof which shall be
effective as though the void or invalid provision had not been contained herein.

      9.5 No modification, rescission, waiver, release or amendment of any
provision of this Agreement shall be made except by a written agreement executed
by Debtor and a duly authorized officer of Secured Party.

      9.6 This is a continuing Agreement which shall remain in full force and
effect until actual receipt by Secured Party of written notice of its revocation
as to future transactions and shall remain in full force and effect thereafter
until all of the Obligation incurred before the receipt of such notice, and all
of the Obligation incurred thereafter under commitments extended by Secured
Party before the receipt of such notice, shall have been paid and performed in
full.

      9.7 No setoff or claim that Debtor now has or may in the future have
against Secured Party shall relieve Debtor from paying or performing the
Obligation.

      9.8 Time is of the essence hereof. If more than one Debtor is named
herein, the word "Debtor" shall mean all and any one or more of them, severally
and collectively. All liability hereunder shall be joint and several. This
Agreement shall be binding upon, and shall inure to the benefit of, the parties
hereto and their heirs, personal representatives, successors and assigns. The
term "Secured Party" shall include not only the original Secured Party hereunder
but also any future owner and holder, including pledgees, of note or notes
evidencing the Obligation. The provisions hereof shall apply to the parties
according to the context thereof and without regard to


                                      9
<PAGE>   10
the number or gender of words or expressions used.

      9.9 Except for telephonic notices permitted herein, any notices or other
communications required or permitted to be given hereunder must be (i) given in
writing and personally delivered or mailed by prepaid certified or registered
mail, or (ii) made by telefacsimile delivered or transmitted, to the party to
whom such notice or communication is directed. Any notice to be personally
delivered may be delivered to the principal offices (determined as of the date
of such delivery) of the party to whom such notice is directed. Any such notice
or other communication shall be deemed to have been given (whether actually
received or not) on the day it is personally delivered as aforesaid; or, if
mailed, on the third day after it is mailed as aforesaid; or, if transmitted by
telefacsimile, on the day that such notice is transmitted as aforesaid. The
designated address of a party shall be the address of that party shown at the
beginning of this Agreement or such other address as that party, from time to
time, may specify by notice to the other parties.

      9.10 A carbon, photographic or other reproduced copy of this Agreement
and/or any financing statement relating hereto shall be sufficient for filing
and/or recording as a financing statement.

10.   DEBTOR PROVISIONS

      10.1 Debtor is executing this Agreement solely for the purpose of
encumbering its interest in the Collateral to secure payment and performance of
the Obligation. Debtor shall not be personally liable for the payment or
performance of the Obligation; the liability of Debtor for the payment and
performance of the Obligation and for any breach or default hereunder shall be
limited to its interest in the Collateral. Secured Party shall accept any
payment or performance of the Obligation by Debtor to the same effect as if made
by Borrower.

      10.2 All advances of principal under the Note shall be made to Borrower
subject to and in accordance with the terms thereof. If Borrower is a
corporation or partnership, it is not necessary for Secured Party to inquire
into the powers of Borrower or the officers, directors, partners or agents
acting or purporting to act on its behalf. Debtor is and shall continue to be
fully informed as to all aspects of the business affairs of Borrower that it
deems relevant to the risks it is assuming and hereby waives and fully
discharges Secured Party from any and all obligations to communicate to Debtor
any facts of any nature whatsoever regarding Borrower and Borrower's business
affairs.

      10.3 Debtor authorizes Secured Party, without notice or demand, without
affecting the obligations of Debtor hereunder or the personal liability of any
person for payment or performance of the Obligation and without affecting the
lien or the priority of the Security Interest, from time to time, at the request
of any person primarily obligated therefor, to renew, compromise, extend,
accelerate or otherwise change the time for payment or performance of, or
otherwise change the terms of, all or any part of the Obligation, including
increase or decrease any rate of interest thereon. Debtor waives and agrees not
to assert: (i) any right to require Secured Party to proceed against Borrower;
(ii) the benefits of any statutory provision limiting the liability


                                      10
<PAGE>   11
of a surety, including without limitation the benefit of Section 12-1641, et
seq., of the Arizona Revised Statutes; and (iii) any defense arising by reason
of any disability or other defense of Borrower or by reason of the cessation
from any cause whatsoever of the liability of Borrower. Debtor shall have no
right of subrogation and hereby waives any right to enforce any remedy which
Secured Party now has, or may hereafter have, against Borrower.

      10.4 Nothing contained herein shall affect or limit the right of Secured
Party to proceed against any person or entity, including Debtor or any partner
in Debtor, with respect to the enforcement of any guarantee or other similar
