                                    GUARANTEE

In consideration of, and as an inducement for, MasterCard International

regulations and policies of MasterCard now and hereinafter at any time in
effect, including, without limitation, all amounts owed by Member to MasterCard
or any member of MasterCard with respect to, or resulting from, Member's
MasterCard transactions, and all amounts paid by MasterCard to any merchant in
fulfillment of Member's obligations to such merchant under any written agreement
between Member and such merchant; provided, however, that the foregoing
obligation of the Guarantor, in the aggregate and regardless of cause shall in
no case exceed the amount of USD 400 million. Each and all of the foregoing
liabilities and obligations of Member are hereby guaranteed by Guarantor and are
hereinafter collectively referred to as the "Obligations". This Guarantee
constitutes of guarantee of payment and not of collection. The Guarantor does
hereby agree that in the event that Member does not or is unable to pay or

the liquidation, dissolution, receivership, insolvency, bankruptcy, assignment
for the benefit of creditors, reorganization, arrangement, composition or
readjustment of, any or other similar proceedings affecting the status,
existence, assets or obligations of, Member), the Guarantor shall immediately
pay such Obligations upon the written demand or demands of MasterCard. Without
limiting the generality of this Guarantee, the Guarantor specifically agrees
that it shall not be necessary or required, and the Guarantor shall not be
entitled to require, that MasterCard file suit or proceed to obtain or assert a
claim for a personal judgment against Member for the Obligations or make any
effort at collection of the Obligations from Member as a condition of enforcing
the liability of the Guarantor under this guarantee or requiring payment of said
Obligations by the Guarantor hereunder. The Guarantor agrees, immediately upon
demand or demands of MasterCard, to reimburse MasterCard for the payment of all
actual costs, fees and expenses, including, without limitation, reasonable
attorney's fees, incurred by MasterCard in the enforcement or attempted
enforcement of any of its rights hereunder.

The Guarantor specifically agrees that it shall not be necessary or required in
order to enforce the obligations of the Guarantor hereunder that there be, and
the Guarantor specifically waives, notice and acceptance of this Guarantee. The
obligations of the Guarantor under this Guarantee shall be absolute and
unconditional and shall remain in full force and effect until the sooner of (a)
MasterCard's consent to this

                                                                               1

Guarantee's termination, (b) Member's termination as a MasterCard member and
thereafter until the Obligations have been fully and satisfactorily discharged
and (c) until the effective date of the revocation contained in a written notice
of revocation sent by Guarantor to MasterCard, which revocation date shall not
be earlier than six (6) months after such notice is received by MasterCard;
provided, however, that any such revocation shall not affect any outstanding
obligation or liability created or incurred for any transaction(s) that are
handled by the Member prior to the effective date of the revocation of this
Guarantee, including any chargebacks, reversals, credits or other adjustments
connected with any such transaction(s).

The Guarantor hereby represents and warrants to MasterCard that: (a) the
Guarantor is a corporation duly organized, validly existing and in good standing
under the laws of Delaware; (b) the Guarantor has the power and authority to
execute and perform this Guarantee, and has duly authorized the execution,
delivery and performance of this Guarantee; (c) no approval is required from any
regulatory body, board, authority or commission, nor from any other
administrative or governmental agency, nor from any other person, firm or
corporation, with respect to the execution of this Guarantee by the Guarantor
and the payment by the Guarantor of all of the Guarantor's obligations
hereunder; (d) this Guarantee constitutes the legal, valid and binding
obligation of the Guarantor, enforceable in accordance with its terms; and (e)
the execution, delivery and performance of the same by the Guarantor will not
violate the Guarantor's charter or bylaws, or any provision of law, any order or
any court or other agency of government, or any indenture, agreement or other
instrument to which the Guarantor is a party, or by or under which the Guarantor
or any of the Guarantor's property is bound, or be in conflict with, result in a
breach of, or constitute (with due notice and/or lapse of time) a default under,
any such indenture, agreement, or other instrument.

Any provision of this Guarantee which is prohibited or unenforceable in any
jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition or unenforceability without invalidating the remaining
provisions hereof, and any such prohibition or unenforceability shall not
invalidate or render unenforceable such provision in any other jurisdiction.

All notices, requests and demands to or upon Guarantor or MasterCard, as
appropriate, shall be deemed duly given or made when received and shall be sent
by certified or registered mail, return receipt requested, postage prepaid,
addressed to the Guarantor at 1900 East Ninth Street, Cleveland, Ohio, 44114,

purposes of receipt of notice from the other by written notice.

                                                                               2

                                  THE FACILITY

                  SECTION 2.1 THE REVOLVING CREDIT COMMITMENTS

                  (a) On the terms and subject to the conditions contained in
this Agreement, each Lender severally agrees to continue to make loans (each,
together with each "Revolving Loan" as defined in and made under the Existing
Credit Agreement, a "Revolving Loan") to the Borrowers from time to time on any
Business Day during the period from the Effective Date until the Revolving
Credit Termination Date in an aggregate amount not to exceed at any time
outstanding for all Revolving Loans by such Lender such Lender's Revolving
Credit Commitment; provided, however, that at no time shall any Lender be
obligated to make a Revolving Loan (i) in excess of such Lender's Ratable
Portion of the Available Credit, (ii) to the extent that the aggregate Revolving
Credit Outstandings, after giving effect to such Revolving Loan, would exceed
the Maximum Credit in effect at such time and (iii) to the extent that, in the
case of any Borrower, the aggregate Revolving Credit Outstandings owing by such
Borrower would exceed the Borrowing Base of such Borrower at such time. Within
the limits of each Lender's Revolving Credit Commitment, amounts of Revolving
Loans repaid may be reborrowed under this Section 2.1.

                  (b) The Borrowers may, at any time, request the Lenders to
provide additional Revolving Credit Commitments in an amount up to $50,000,000
(the "Facility Increase");

provided, however, that (i) the Borrowers shall have given the Administrative
Agent at least 60 days prior written notice of its intention to effect a
Facility Increase and the desired amount of such Facility Increase, (ii) the
conditions precedent to a Borrowing set forth in Section 3.2 (Conditions
Precedent to Each Loan and Letter of Credit) are satisfied as of the Facility
Increase Effective Date and (iii) an opinion of counsel to the Loan Parties in
form and substance and from counsel reasonably satisfactory to the
Administrative Agent and addressed to the Administrative Agent, the Issuers and
the Lenders and addressing such matters as any Lender through the Administrative
Agent may reasonably request (including an opinion as to no conflicts with other
Indebtedness) shall be delivered to the Administrative Agent. The Borrowers
shall have the right to offer such increase to (x) the Lenders, and each Lender
will have the right, but not the obligation, to commit to all or a portion of
the proposed Facility Increase or (y) Eligible Assignees; provided, however,
that the minimum additional Revolving Credit Commitment of each such Lender or
Eligible Assignee equals or exceeds $5,000,000 and such Lender or Eligible
Assignee executes an Assumption Agreement pursuant to which such Lender or
Eligible Assignee agrees to commit to all or a portion of such Facility Increase
and, in the case of an Eligible Assignee, to be bound by the terms of this
Agreement as a Lender. On the effective date provided for in the Assumption
Agreements providing for a Facility Increase (the "Facility Increase Effective
Date"), the Revolving Credit Commitments shall be increased by the amount
committed to by each Lender or Eligible Assignee on the Facility Increase Date.
In the event there are Lenders and Eligible Assignees that have committed to a
Facility Increase in excess of the maximum amount requested (or permitted), then
the Administrative Agent shall have the right to allocate such commitments,
first to Lenders and then to Eligible Assignees, on whatever basis the
Administrative Agent determines is appropriate in consultation with the
Borrowers. The Administrative Agent and the Lenders reserve the right to request
the Borrowers to pay compensation for such additional commitments for the
Facility Increase and such Facility Increase shall not become effective until
such fees shall have been paid. Only one Facility Increase may be effected
pursuant to this clause (b).

                  SECTION 2.2 BORROWING PROCEDURES

(a) Each Revolving Credit Borrowing shall be made on notice given by any
Borrower to the Administrative Agent not later than 11:00 A.M. (New York City
time) (i) one Business Day, in the case of a Borrowing of Base Rate Loans and
(ii) three Business Days, in the case of a Borrowing of Eurodollar Rate Loans,
prior to the date of the proposed Revolving Credit Borrowing. Each such notice
shall be in substantially the form of Exhibit C (Form of Notice of Borrowing) (a
"Notice of Borrowing"), specifying (A) the date of such proposed Revolving
Credit Borrowing, (B) the aggregate amount of such proposed Revolving Credit
Borrowing, (C) whether any portion of the proposed Revolving Credit Borrowing
will be of Base Rate Loans or Eurodollar Rate Loans, (D) the initial Interest
Period or Periods for any such Eurodollar Rate Loans and (E) the Available
Credit (after giving effect to the proposed Revolving Credit Borrowing). The
Revolving Loans shall be made as Base Rate Loans unless, subject to Section 2.14
(Special Provisions Governing Eurodollar Rate Loans), the Notice of Borrowing
specifies that all or a portion thereof shall be Eurodollar Rate Loans;
provided, however, that the Interest Period of any Eurodollar Rate Loan made
before the Syndication Completion Date shall be determined by the Administrative
Agent in its sole discretion. Notwithstanding anything to the contrary contained
in clause (a) of Section 2.3 (Swing Loans), if any Notice of Borrowing requests
a Revolving Credit Borrowing of Base Rate Loans, the Administrative Agent may,
in its sole discretion, make a Swing Loan available to the applicable Borrower
in an aggregate amount not to exceed such proposed Revolving Credit Borrowing,
and the aggregate amount of the

                                           AMENDED AND RESTATED CREDIT AGREEMENT
                                                             SUNTRON CORPORATION

corresponding proposed Revolving Credit Borrowing shall be reduced accordingly
by the principal amount of such Swing Loan. Each Revolving Credit Borrowing
shall be in an aggregate amount of not less than $3,000,000 or an integral
multiple of $1,000,000 in excess thereof.

                  (b) The Administrative Agent shall give to each Lender prompt
notice of the Administrative Agent's receipt of a Notice of Borrowing and, if
Eurodollar Rate Loans are properly requested in such Notice of Borrowing, the
applicable interest rate determined pursuant to Section 2.14(a) (Determination
of Interest Rate). Each Lender shall, before 11:00 A.M. (New York City time) on
the date of the proposed Borrowing, make available to the Administrative Agent
at its address referred to in Section 11.8 (Notices, Etc.), in immediately
available funds, such Lender's Ratable Portion of such proposed Borrowing. After
the Administrative Agent's receipt of such funds and upon fulfillment of the
applicable conditions set forth in Section 3.1 (Conditions Precedent to the
Effectiveness of this Agreement) and Section 3.2 (Conditions Precedent to Each
Loan and Letter of Credit), the Administrative Agent shall make such funds
available to the applicable Borrower.

                  (c) Unless the Administrative Agent shall have received notice
from a Lender prior to the date of any proposed Borrowing by any Borrower that
such Lender shall not make available to the Administrative Agent such Lender's
Ratable Portion of such Borrowing, the Administrative Agent may assume that such
Lender has made such Ratable Portion available to the Administrative Agent on
the date of such Borrowing in accordance with this Section 2.2 and the
Administrative Agent may, in reliance upon such assumption, make available to
such Borrower on such date a corresponding amount. If and to the extent that
such Lender shall not have so made such Ratable Portion available to the
Administrative Agent, such Lender and such Borrower severally agree to repay to
the Administrative Agent forthwith on demand such corresponding amount together
with interest thereon, for each day from the date such amount is made available
to such Borrower until the date such amount is repaid to the Administrative
Agent, at (i) in the case of such Borrower, the interest rate applicable at the
time to the Loans comprising such Borrowing and (ii) in the case of such Lender,
the Federal Funds Rate for the first Business Day and thereafter at the interest
rate applicable at the time to the Loans comprising such Borrowing. If such
Lender shall repay to the Administrative Agent such corresponding amount, such
amount so repaid shall constitute such Lender's Loan as part of such Borrowing
for purposes of this Agreement. If such Borrower shall repay to the
Administrative Agent such corresponding amount, such payment shall not relieve
such Lender of any obligation it may have hereunder to such Borrower.

                  (d) The failure of any Lender to make the Loan or any payment
required by it on the date specified (a "Non-Funding Lender"), including any
payment in respect of its participation in Swing Loans and Letter of Credit
Obligations, shall not relieve any other Lender of its obligations to make such
Loan or payment on such date but no such other Lender shall be responsible for
the failure of any Non-Funding Lender to make a Loan or payment required under
this Agreement.

                  SECTION  2.3 SWING LOANS

                  (a) On the terms and subject to the conditions contained in
this Agreement, the Swing Loan Lender may, in its sole discretion, make loans
(each, together with each "Swing Loan" as defined in and made under the Existing
Credit Agreement, a "Swing Loan") otherwise available to the Borrowers under the
Facility from time to time on any Business Day during the period from the
Effective Date until the Revolving Credit Termination Date in an aggregate

                                                             SUNTRON CORPORATION

amount at any time outstanding at any time not to exceed $10,000,000; provided,
however, that the Swing Loan Lender shall not make any Swing Loan to the extent
that, after giving effect to such Swing Loan, the aggregate Revolving Credit
Obligations would exceed the Maximum Credit. The Swing Loan Lender shall be
entitled to rely on the most recent Borrowing Base Certificate delivered to the
Administrative Agent. Each Swing Loan shall be a Base Rate Loan and must be
repaid in full upon any Revolving Credit Borrowing hereunder and shall in any
event mature no later than the Revolving Credit Termination Date. Within the
limits set forth in the first sentence of this clause (a), amounts of Swing
Loans repaid may be reborrowed under this clause (a). Swing Loans shall be Base
Rate Loans.

                  (b) In order to request a Swing Loan, a Borrower shall
telecopy (or forward by electronic mail or similar means) to the Administrative
Agent a duly completed request setting forth the date, the requested amount and
date of the Swing Loan (a "Swing Loan Request"), to be received by the
Administrative Agent not later than 1:00 P.M. (New York City time) on the day of
the proposed borrowing. The Administrative Agent shall promptly notify the Swing
Loan Lender of the details of the requested Swing Loan. Subject to the terms of
this Agreement, the Swing Loan Lender may make a Swing Loan available to the
Administrative Agent in an amount up to the amount requested and, in turn, the
Administrative Agent shall make such amounts available to such Borrower on the
date of the relevant Swing Loan Request. The Swing Loan Lender shall not make
any Swing Loan in the period commencing on the first Business Day after it
receives written notice from any Lender that one or more of the conditions
precedent contained in Section 3.2 (Conditions Precedent to Each Loan and Letter
of Credit) shall not on such date be satisfied, and ending when such conditions
are satisfied. The Swing Loan Lender shall not otherwise be required to
determine that, or take notice whether, the conditions precedent set forth in
Section 3.2 (Conditions Precedent to Each Loan and Letter of Credit) have been
satisfied in connection with the making of any Swing Loan.

                  (c) The Swing Loan Lender shall notify the Administrative
Agent in writing (which writing may be a telecopy or electronic mail) weekly, by
no later than 10:00 A.M. (New York City time) on the first Business Day of each
week, of the aggregate principal amount of its Swing Loans then outstanding.

                  (d) The Swing Loan Lender may demand at any time that each
Lender pay to the Administrative Agent, for the account of the Swing Loan
Lender, in the manner provided in clause (e) below, such Lender's Ratable
Portion of all or a portion of the outstanding Swing Loans, which demand shall
be made through the Administrative Agent, shall be in writing and shall specify
the outstanding principal amount of Swing Loans demanded to be paid.

                  (e) The Administrative Agent shall forward each notice
referred to in clause (c) above and each demand referred to in clause (d) above
to each Lender on the day such notice or such demand is received by the
Administrative Agent (except that any such notice or demand received by the
Administrative Agent after 2:00 P.M. (New York City time) on any Business Day or
any such demand received on a day that is not a Business Day shall not be
required to be forwarded to the Lenders by the Administrative Agent until the
next succeeding Business Day), together with a statement prepared by the
Administrative Agent specifying the amount of each Lender's Ratable Portion of
the aggregate principal amount of the Swing Loans stated to be outstanding in
such notice or demanded to be paid pursuant to such demand, and, notwithstanding
whether or not the conditions precedent set forth in Section 3.2 (Conditions
Precedent to Each Loan and Letter of Credit) shall have been satisfied (which
conditions precedent the Lenders hereby irrevocably waive), each Lender shall,
before 11:00 A.M. (New York City time) on the

                                           AMENDED AND RESTATED CREDIT AGREEMENT
                                                             SUNTRON CORPORATION

Business Day next succeeding the date of such Lender's receipt of such written
statement, make available to the Administrative Agent, in immediately available
funds, for the account of the Swing Loan Lender, the amount specified in such
statement. Upon such payment by a Lender, such Lender shall, except as provided
in clause (f) below, be deemed to have made a Revolving Loan to the applicable
Borrower. The Administrative Agent shall use such funds to repay the Swing Loans
to the Swing Loan Lender. To the extent that any Lender fails to make such
payment available to the Administrative Agent for the account of the Swing Loan
Lender, such Borrower shall repay such Swing Loan on demand.

                  (f) Upon the occurrence of a Default under Section 9.1(f)
(Events of Default), each Lender shall acquire, without recourse or warranty, an
undivided participation in each Swing Loan otherwise required to be repaid by
such Lender pursuant to clause (e) above, which participation shall be in a
principal amount equal to such Lender's Ratable Portion of such Swing Loan, by
paying to the Swing Loan Lender on the date on which such Lender would otherwise
have been required to make a payment in respect of such Swing Loan pursuant to
clause (e) above, in immediately available funds, an amount equal to such
Lender's Ratable Portion of such Swing Loan. If such amount is not in fact made
available by such Lender to the Swing Loan Lender on such date, the Swing Loan
Lender shall be entitled to recover such amount on demand from such Lender
together with interest accrued from such date at the Federal Funds Rate for the
first Business Day after such payment was due and thereafter at the rate of
interest then applicable to Base Rate Loans.

                  (g) From and after the date on which any Lender is deemed to
have made a Revolving Loan pursuant to clause (e) above with respect to any
Swing Loan or purchases an undivided participation interest in a Swing Loan
pursuant to clause (f) above, the Swing Loan Lender shall promptly distribute to
such Lender such Lender's Ratable Portion of all payments of principal of and
interest received by the Swing Loan Lender on account of such Swing Loan other
than those received from a Lender pursuant to clause (e) or (f) above.

                  SECTION  2.4 LETTERS OF CREDIT

                  (a) On the terms and subject to the conditions contained in
this Agreement, each Issuer agrees to issue one or more Letters of Credit at the
request of a Borrower for the account of such Borrower from time to time during
the period commencing on the Effective Date and ending on the earlier of the
Revolving Credit Termination Date and 30 days prior to the Scheduled Termination
Date; provided, however, that no Issuer shall be under any obligation to issue
any Letter of Credit if:

                           (i)      any order, judgment or decree of any
         Governmental Authority or arbitrator shall purport by its terms to
         enjoin or restrain such Issuer from issuing such Letter of Credit or
         any Requirement of Law applicable to such Issuer or any request or
         directive (whether or not having the force of law) from any
         Governmental Authority with jurisdiction over such Issuer shall
         prohibit, or request that such Issuer refrain from, the issuance of
         letters of credit generally or such Letter of Credit in particular or
         shall impose upon such Issuer with respect to such Letter of Credit any
         restriction or reserve or capital requirement (for which such Issuer is
         not otherwise compensated) not in effect on the date of this Agreement
         or result in any unreimbursed loss, cost or expense that was not
         applicable, in effect or known to such Issuer as of the date of this
         Agreement and that such Issuer in good faith deems material to it;

                                                             SUNTRON CORPORATION

                           (ii)     such Issuer shall have received written
         notice from the Administrative Agent, any Lender or any Borrower, on or
         prior to the requested date of issuance of such Letter of Credit, that
         one or more of the applicable conditions contained in Section 3.1
         (Conditions Precedent to the Effectiveness of this Agreement) or
         Section 3.2 (Conditions Precedent to Each Loan and Letter of Credit) is
         not then satisfied;

                           (iii)    after giving effect to the issuance of such
         Letter of Credit, the aggregate Revolving Credit Outstandings would
         exceed the Maximum Credit at such time or the aggregate Revolving
         Credit Outstandings owing by the Borrower for whose account such Letter
         of Credit is being issued exceeds such Borrower's Borrowing Base;

                           (iv)     after giving effect to the issuance of such
         Letter of Credit, the sum of (i) the Letter of Credit Undrawn Amounts
         at such time and (ii) the Reimbursement Obligations at such time
         exceeds $10,000,000; or

                           (v)      any fees due in connection with a requested
         issuance have not been paid.

None of the Lenders (other than the Issuers in their capacity as such) shall
have any obligation to issue any Letter of Credit.

                  (b) In no event shall the expiration date of any Letter of
Credit (i) be more than one year after the date of issuance thereof or (ii) be
less than seven days prior to the Scheduled Termination Date; provided, however,
that any Letter of Credit with a one-year term may provide for the renewal
thereof for additional one-year periods (which shall in no event extend beyond
the expiry date referred to in clause (ii) above).

                  (c) In connection with the issuance of each Letter of Credit
for the account of any Borrower, such Borrower shall give the relevant Issuer
and the Administrative Agent at least two Business Days' prior written notice,
in substantially the form of Exhibit D (Form of Letter of Credit Request) (or in
such other written or electronic form as is acceptable to the Issuer), of the
requested issuance of such Letter of Credit (a "Letter of Credit Request"). Such
notice shall be irrevocable and shall specify the Issuer of such Letter of
Credit, the stated amount of the Letter of Credit requested, which stated amount
shall not be less than $50,000, the date of issuance of such requested Letter of
Credit (which day shall be a Business Day), the date on which such Letter of
Credit is to expire (which date shall be a Business Day), and the Person for
whose benefit the requested Letter of Credit is to be issued. Such notice, to be
effective, must be received by the relevant Issuer and the Administrative Agent
not later than 11:00 A.M. (New York City time) on the second Business Day prior
to the requested issuance of such Letter of Credit.

                  (d) Subject to the satisfaction of the conditions set forth in
this Section 2.4, the relevant Issuer shall, on the requested date, issue a
Letter of Credit on behalf of the applicable Borrower in accordance with such
Issuer's usual and customary business practices. No Issuer shall issue any
Letter of Credit in the period commencing on the first Business Day after it
receives written notice from any Lender that one or more of the conditions
precedent contained in Section 3.2 (Conditions Precedent to Each Loan and Letter
of Credit) shall not on such date be satisfied, and ending when such conditions
are satisfied. The relevant Issuer shall not otherwise be required to determine
that, or take notice whether, the conditions precedent set forth in

                                       41

                                           AMENDED AND RESTATED CREDIT AGREEMENT
                                                             SUNTRON CORPORATION

Section 3.2 (Conditions Precedent to Each Loan and Letter of Credit) have been
satisfied in connection with the issuance of any Letter of Credit.

                  (e) If requested by the relevant Issuer, prior to the issuance
of each Letter of Credit for the account of any Borrower by such Issuer, and as
a condition of such issuance and of the participation of each Lender in the
Letter of Credit Obligations arising with respect thereto, such Borrower shall
have delivered to such Issuer a letter of credit reimbursement agreement, in
such form as the Issuer may employ in its ordinary course of business for its
own account (a "Letter of Credit Reimbursement Agreement"), signed by such
Borrower, and such other documents or items as may be required pursuant to the
terms thereof. In the event of any conflict between the terms of any Letter of
Credit Reimbursement Agreement and this Agreement, the terms of this Agreement
shall govern.

                  (f) Each Issuer shall:

                           (i)      give the Administrative Agent written notice
         (or telephonic notice confirmed promptly thereafter in writing), which
         writing may be a telecopy or electronic mail, of the issuance or
         renewal of a Letter of Credit issued by it for the account of any
         Borrower, of all drawings under a Letter of Credit issued by it and the
         payment (or the failure to pay when due) by such Borrower of any
         Reimbursement Obligation when due (which notice the Administrative
         Agent shall promptly transmit by telecopy, electronic mail or similar
         transmission to each Lender);

                           (ii)     upon the request of any Lender, furnish to
         such Lender copies of any Letter of Credit Reimbursement Agreement to
         which such Issuer is a party and such other documentation as may
         reasonably be requested by such Lender; and

                           (iii)    no later than 10 Business Days following the
         last day of each calendar month, provide to the Administrative Agent
         (and the Administrative Agent shall provide a copy to each Lender
         requesting the same) and the Company separate schedules for Documentary
         and Standby Letters of Credit issued by it, in form and substance
         reasonably satisfactory to the Administrative Agent, setting forth the
         aggregate Letter of Credit Obligations outstanding at the end of each
         month and any information requested by the Company or the
         Administrative Agent relating thereto.

                  (g) Immediately upon the issuance by an Issuer of a Letter of
Credit for the account of any Borrower in accordance with the terms and
conditions of this Agreement, such Issuer shall be deemed to have sold and
transferred to each Lender, and each Lender shall be deemed irrevocably and
unconditionally to have purchased and received from such Issuer, without
recourse or warranty, an undivided interest and participation, to the extent of
such Lender's Ratable Portion, in such Letter of Credit and the obligations of
such Borrower with respect thereto (including all Letter of Credit Obligations
with respect thereto) and any security therefor and guaranty pertaining thereto.

                  (h) Each Borrower for whose account a Letter of Credit has
been issued agrees to pay to the Issuer of such Letter of Credit the amount of
all Reimbursement Obligations owing to such Issuer under such Letter of Credit
when such amounts are due and payable, irrespective of any claim, set-off,
defense or other right that any Borrower may have at any time against such
Issuer or any other Person. In the event that any Issuer makes any payment under
any Letter of Credit and no Borrower shall have repaid such amount to such
Issuer pursuant to this clause (h)

                                       42
<PAGE>

                                           AMENDED AND RESTATED CREDIT AGREEMENT
                                                             SUNTRON CORPORATION

or such payment is rescinded or set aside for any reason, such Reimbursement
Obligation shall bear interest computed from the date on which such
Reimbursement Obligation arose to the date of repayment in full at the rate of
interest applicable to Revolving Loans bearing interest at a rate based on the
Base Rate during such period, and such Issuer shall promptly notify the
Administrative Agent, that shall promptly notify each Lender of the failure to
repay such Reimbursement Obligation, and each Lender shall promptly and
unconditionally pay to the Administrative Agent for the account of such Issuer
the amount of such Lender's Ratable Portion of such payment in Dollars and in
immediately available funds. If the Administrative Agent so notifies such Lender
prior to 11:00 A.M. (New York City time) on any Business Day, such Lender shall
make available to the Administrative Agent for the account of such Issuer its
Ratable Portion of the amount of such payment on such Business Day in
immediately available funds. Upon such payment by a Lender, such Lender shall,
except during the continuance of a Default or Event of Default under Section
9.1(f) (Events of Default) and notwithstanding whether or not the conditions
precedent set forth in Section 3.2 (Conditions Precedent to Each Loan and Letter
of Credit) shall have been satisfied (which conditions precedent the Lenders
hereby irrevocably waive) be deemed to have made a Revolving Loan to the
Borrowers in the principal amount of such payment. Whenever any Issuer receives
from any Borrower a payment of a Reimbursement Obligation as to which the
Administrative Agent has received for the account of such Issuer any payment
from a Lender pursuant to this clause (h), such Issuer shall pay to the
Administrative Agent and the Administrative Agent shall promptly pay to each
Lender, in immediately available funds, an amount equal to such Lender's Ratable
Portion of the amount of such payment adjusted, if necessary, to reflect the
respective amounts the Lenders have paid in respect of such Reimbursement
Obligation.

                  (i) Each Borrower's obligation to pay each Reimbursement
Obligation and the obligations of the Lenders to make payments to the
Administrative Agent for the account of the Issuers with respect to Letters of
Credit issued for the account of such Borrower shall be absolute, unconditional
and irrevocable and shall be performed strictly in accordance with the terms of
this Agreement, under any and all circumstances whatsoever, including the
occurrence of any Default or Event of Default, and irrespective of:

                           (i)      any lack of validity or enforceability of
         any Letter of Credit or any Loan Document, or any term or provision
         therein;

                           (ii)     any amendment or waiver of or any consent to
         departure from all or any of the provisions of any Letter of Credit or
         any Loan Document;

                           (iii)    the existence of any claim, set off, defense
         or other right that any Borrower, any other party guaranteeing, or
         otherwise obligated with, any Borrower, any Subsidiary or other
         Affiliate thereof or any other Person may at any time have against the
         beneficiary under any Letter of Credit, any Issuer, the Administrative
         Agent or any Lender or any other Person, whether in connection with
         this Agreement, any other Loan Document or any other related or
         unrelated agreement or transaction;

                           (iv)     any draft or other document presented under
         a Letter of Credit proving to be forged, fraudulent, invalid or
         insufficient in any respect or any statement therein being untrue or
         inaccurate in any respect;

                                           AMENDED AND RESTATED CREDIT AGREEMENT
                                                             SUNTRON CORPORATION

                           (v)      payment by the Issuer under a Letter of
         Credit against presentation of a draft or other document that does not
         comply with the terms of such Letter of Credit; and

                           (vi)     any other act or omission to act or delay of
         any kind of the Issuer, the Lenders, the Administrative Agent or any
         other Person or any other event or circumstance whatsoever, whether or
         not similar to any of the foregoing, that might, but for the provisions
         of this Section 2.4, constitute a legal or equitable discharge of any
         Borrower's obligations hereunder.

Any action taken or omitted to be taken by the relevant Issuer under or in
connection with any Letter of Credit, if taken or omitted in the absence of
gross negligence or willful misconduct, shall not put such Issuer under any
resulting liability to any Borrower or any Lender. In determining whether drafts
and other documents presented under a Letter of Credit comply with the terms
thereof, the Issuer may accept documents that appear on their face to be in
order, without responsibility for further investigation, regardless of any
notice or information to the contrary and, in making any payment under any
Letter of Credit the Issuer may rely exclusively on the documents presented to
it under such Letter of Credit as to any and all matters set forth therein,
including reliance on the amount of any draft presented under such Letter of
Credit, whether or not the amount due to the beneficiary thereunder equals the
amount of such draft and whether or not any document presented pursuant to such
Letter of Credit proves to be insufficient in any respect, if such document on
its face appears to be in order, and whether or not any other statement or any
other document presented pursuant to such Letter of Credit proves to be forged
or invalid or any statement therein proves to be inaccurate or untrue in any
respect whatsoever, and any noncompliance in any immaterial respect of the
documents presented under such Letter of Credit with the terms thereof shall, in
each case, be deemed not to constitute willful misconduct or gross negligence of
the Issuer.

                  (j) If and to the extent such Lender shall not have so made
its Ratable Portion of the amount of the payment required by clause (i) above
available to the Administrative Agent for the account of such Issuer, such
Lender agrees to pay to the Administrative Agent for the account of such Issuer
forthwith on demand such amount together with interest thereon, for the first
Business Day after payment was first due at the Federal Funds Rate and,
thereafter until such amount is repaid to the Administrative Agent for the
account of such Issuer, at the rate per annum applicable to Base Rate Loans
under the Facility. The failure of any Lender to make available to the
Administrative Agent for the account of such Issuer its Ratable Portion of any
such payment shall not relieve any other Lender of its obligation hereunder to
make available to the Administrative Agent for the account of such Issuer its
Ratable Portion of any payment on the date such payment is to be made, but no
Lender shall be responsible for the failure of any other Lender to make
available to the Administrative Agent for the account of the Issuer such other
Lender's Ratable Portion of any such payment.

         SECTION 2.5 REDUCTION AND TERMINATION OF THE REVOLVING CREDIT
COMMITMENTS

                  (a) The Company may, upon at least three Business Days' prior
notice to the Administrative Agent, terminate in whole or reduce in part ratably
the unused portions of the respective Revolving Credit Commitments of the
Lenders; provided, however, that each partial reduction shall be in the
aggregate amount of not less than $5,000,000 or an integral multiple of
$1,000,000 in excess thereof.

                                           AMENDED AND RESTATED CREDIT AGREEMENT
                                                             SUNTRON CORPORATION

                  (b) The then current Revolving Credit Commitments shall be
reduced on each date on which a prepayment of Revolving Loans or Swing Loans is
made pursuant to subclause (i) (other than for Asset Sales made pursuant to and
in accordance with clause (b) of Section 8.4 (Sale of Assets)) or (ii) of clause
(a) of Section 2.9 (Mandatory Prepayments) or would be required to be made had
the outstanding Revolving Loans and Swing Loans equaled the Revolving Credit
Commitments then in effect, in each case in the amount of such prepayment (or
deemed prepayment) (and the Revolving Credit Commitment of each Lender shall be
reduced by its Ratable Portion of such amount).

                  SECTION  2.6 REPAYMENT OF LOANS

                  Each Borrower promises to repay the entire unpaid principal
amount of the Revolving Loans and the Swing Loans owing by it on the Scheduled
Termination Date.

                  SECTION  2.7 EVIDENCE OF DEBT

                  (a) Each Lender shall maintain in accordance with its usual
practice an account or accounts evidencing Indebtedness of each Borrower to such
Lender resulting from each Loan of such Lender from time to time, including the
amounts of principal and interest payable and paid to such Lender from time to
time under this Agreement.

                  (b) The Administrative Agent shall maintain accounts in
accordance with its usual practice in which it shall record (i) the amount of
each Loan made and, if a Eurodollar Rate Loan, the Interest Period applicable
thereto, (ii) the amount of any principal or interest due and payable by any
Borrower to each Lender hereunder and (iii) the amount of any sum received by
the Administrative Agent hereunder from any Borrower and each Lender's share
thereof, if applicable.

                  (c) The entries made in the accounts maintained pursuant to
clauses (a) and (b) above shall, to the extent permitted by applicable law, be
prima facie evidence of the existence and amounts of the obligations recorded
therein; provided, however, that the failure of any Lender or the Administrative
Agent to maintain such accounts or any error therein shall not in any manner
affect the obligations of any Borrower to repay the Loans in accordance with
their terms.

                  (d) Notwithstanding any other provision of the Agreement, in
the event that any Lender requests that a Borrower execute and deliver a
promissory note or notes payable to such Lender in order to evidence the
Indebtedness owing to such Lender by such Borrower hereunder, such Borrower
shall promptly execute and deliver a Revolving Credit Note or Revolving Credit
Notes to such Lender evidencing any Revolving Loans of such Lender,
substantially in the form of Exhibit B (Form of Revolving Credit Note).

                  SECTION 2.8 OPTIONAL PREPAYMENTS

                  Any Borrower may prepay the outstanding principal amount of
the Revolving Loans or Swing Loans owing by it at any time in whole or in part,
without premium or penalty; provided, however, that if any prepayment of any
Eurodollar Rate Loan is made by any Borrower other than on the last day of an
Interest Period for such Loan, such Borrower shall also pay any amounts owing
pursuant to Section 2.14(e) (Breakage Costs). Upon the giving of such notice of
prepayment, the principal amount of Revolving Loans specified to be prepaid
shall become due and payable on the date specified for such prepayment.

                                           AMENDED AND RESTATED CREDIT AGREEMENT
                                                             SUNTRON CORPORATION

                  SECTION 2.9 MANDATORY PREPAYMENTS

                  (a) Upon receipt by the Company, any Borrower or any of their
respective Subsidiaries of Net Cash Proceeds arising (i) from an Asset Sale, the
Borrowers shall immediately prepay the Loans (or provide cash collateral in
respect of Letters of Credit) in an amount equal to 100% of such Net Cash
Proceeds (except for Net Cash Proceeds that, together with all other Net Cash
Proceeds arising from Asset Sales received by the Company, any Borrower or any
of their respective Subsidiaries since the Effective Date, do not exceed
$2,000,000 in the aggregate) and (ii) from a Property Loss Event, the Borrowers
shall immediately prepay the Loans (or provide cash collateral in respect of
Letters of Credit) in an amount equal to 100% of such Net Cash Proceeds and
(iii) from an Equity Issuance or Debt Issuance, the Borrowers shall immediately
prepay the Loans (or provide cash collateral in respect of Letters of Credit) in
an amount equal to 100% of such Net Cash Proceeds; provided, however, that, in
the case of any Net Cash Proceeds arising from a Reinvestment Event, the
Borrowers shall prepay the Loans (or provide cash collateral in respect of
Letters of Credit) in an amount equal to the Reinvestment Prepayment Amount
applicable to such Reinvestment Event, if any, on the Reinvestment Prepayment
Date with respect to such Reinvestment Event and, pending application of such
proceeds as specified in the Reinvestment Notice, shall pay the same to the
Administrative Agent to be held in a Cash Collateral Account. Any such mandatory
prepayment shall be applied in accordance with clause (b) below.

                  (b) Any prepayments made by any Borrower required to be
applied in accordance with this clause (b) shall be applied as follows: first,
to repay the outstanding principal balance of the Swing Loans until such Swing
Loans shall have been repaid in full; second, to repay the outstanding principal
balance of the Revolving Loans until such Revolving Loans shall have been paid
in full; and then, to provide cash collateral for any Letter of Credit
Obligations in the manner set forth in Section 9.3 (Actions in Respect of
Letters of Credit) until all such Letter of Credit Obligations have been fully
cash collateralized in the manner set forth therein.

                  (c) If at any time, (x) the aggregate Revolving Credit
Outstandings owing by the Borrowers exceed the Maximum Credit at such time or
(y) the aggregate Revolving Credit Outstandings owing by any Borrower exceeds
such Borrower's Borrowing Base, the Borrowers or such Borrower, as the case may
be, shall forthwith prepay the Swing Loans first and then the Revolving Loans of
the Borrowers or such Borrower, as applicable, then outstanding in an amount
equal to such excess. If any such excess remains after repayment in full of the
aggregate outstanding Swing Loans and Revolving Loans of the Borrowers or such
Borrower (as the case may be), the Borrowers or such Borrower, as applicable,
shall provide cash collateral for the Letter of Credit Obligations in the manner
set forth in Section 9.3 (Actions in Respect of Letters of Credit) to the extent
required to eliminate such excess.

                  (d) The Borrowers hereby irrevocably waive the right to direct
the application of all funds in the Cash Collateral Account (other than an
amount equal to any proceeds arising from a Reinvestment Event that are held in
the Cash Collateral Account pending application of such proceeds as specified in
a Reinvestment Notice) and agree that the Administrative Agent may, and, upon
the written direction of the Requisite Lenders or Supermajority Lenders, shall,
except as provided in Section 2.13(f) (Payments and Computations), apply all
payments in respect of any Obligations and all available funds in the Cash
Collateral Account on a daily basis as follows: first, to repay the outstanding
principal amount of the Swing Loans until such Swing Loans have been repaid in
full; second, to repay the outstanding principal balance of the Revolving Loans

                                                             SUNTRON CORPORATION

until such Revolving Loans shall have been repaid in full; and then to any other
Obligation then due and payable. The Administrative Agent agrees so to apply
such funds and the Borrowers consent to such application. If, following such
application, there are no Loans outstanding and no other Obligations that are
then due and payable (and cash collateral has been provided in the amount of
105% of all outstanding Letter of Credit Obligations), then the Administrative
Agent shall cause any remaining funds in the Cash Collateral Account to be paid
at the written direction of the Company.

                  SECTION 2.10 INTEREST

                  (a) Rate of Interest. All Loans and the outstanding amount of
all other Obligations shall bear interest, in the case of Loans, on the unpaid
principal amount thereof from the date such Loans are made and, in the case of
such other Obligations, from the date such other Obligations are due and payable
until, in all cases, paid in full, except as otherwise provided in clause (c)
below, as follows:

                           (i)      if a Base Rate Loan or such other
         Obligation, at a rate per annum equal to the sum of (A) the Base Rate
         as in effect from time to time, plus (B) the Applicable Margin; and

                           (ii)     if a Eurodollar Rate Loan, at a rate per
         annum equal to the sum of (A) the Eurodollar Rate determined for the
         applicable Interest Period, plus (B) the Applicable Margin in effect
         from time to time during such Eurodollar Interest Period.

                  (b) Interest Payments. (i) Interest accrued on each Base Rate
Loan (other than Swing Loans) shall be payable in arrears (A) on the last
Business Day of each calendar month, commencing on the first such day following
the making of such Base Rate Loan and (B) if not previously paid in full, at
maturity (whether by acceleration or otherwise) of such Base Rate Loan; (ii)
interest accrued on Swing Loans shall be payable in arrears on the first
Business Day of the immediately succeeding calendar month; (iii) interest
accrued on each Eurodollar Rate Loan shall be payable in arrears (A) on the last
day of each Interest Period applicable to such Loan and if such Interest Period
has a duration of more than three months, on each day during such Interest
Period occurring exactly three months or an integral multiple thereof after the
first day of such Interest Period, (B) upon the payment or prepayment thereof in
full or in part and (C) if not previously paid in full, at maturity (whether by
acceleration or otherwise) of such Eurodollar Rate Loan; and (iv) interest
accrued on the amount of all other Obligations shall be payable on demand from
and after the time such Obligation becomes due and payable (whether by
acceleration or otherwise).

                  (c) Default Interest. Notwithstanding the rates of interest
specified in clause (a) above or elsewhere herein, except as otherwise agreed by
the Requisite Lenders, effective immediately upon the occurrence of an Event of
Default and for as long thereafter as such Event of Default shall be continuing,
the principal balance of all Loans and the amount of all other Obligations shall
bear interest at a rate that is two percent per annum in excess of the rate of
interest applicable to such Obligations from time to time.

                  SECTION 2.11 CONVERSION/CONTINUATION OPTION

                  (a) A Borrower may elect (i) at any time to convert Base Rate
Loans (other than Swing Loans) owing by it or any portion thereof to Eurodollar
Rate Loans or (ii) at the end of any

applicable Interest Period, to convert Eurodollar Rate Loans owing by it or any
portion thereof into Base Rate Loans or to continue such Eurodollar Rate Loans
or any portion thereof for an additional Interest Period; provided, however,
that the aggregate amount of the Eurodollar Loans for each Interest Period must
be in the amount of $3,000,000 or an integral multiple of $1,000,000 in excess
thereof. Each conversion or continuation shall be allocated among the Loans of
each Lender in accordance with its Ratable Portion. Each such election shall be
in substantially the form of Exhibit E (Form of Notice of Conversion or
Continuation) (a "Notice of Conversion or Continuation") and shall be made by
giving the Administrative Agent at least three Business Days' prior written
notice specifying (A) the amount and type of Loan being converted or continued,
(B) in the case of a conversion to or a continuation of Eurodollar Rate Loans,
the applicable Interest Period and (C) in the case of a conversion, the date of
conversion (which date shall be a Business Day and, if a conversion from
Eurodollar Rate Loans, shall also be the last day of the applicable Interest
Period).

                  (b) The Administrative Agent shall promptly notify each Lender
of its receipt of a Notice of Conversion or Continuation and of the options
selected therein. Notwithstanding the foregoing, (i) no conversion in whole or
in part of Base Rate Loans to Eurodollar Rate Loans shall be permitted at any
time prior to the Syndication Completion Date except to Eurodollar Rate Loans
with Interest Periods otherwise determined by the Administrative Agent pursuant
to clause (a) of Section 2.2 (Borrowing Procedures) and (ii) no conversion in
whole or in part of Base Rate Loans to Eurodollar Rate Loans, and no
continuation in whole or in part of Eurodollar Rate Loans upon the expiration of
any applicable Interest Period, shall be permitted at any time at which (i) an
Event of Default shall have occurred and be continuing or (ii) the continuation
of, or conversion into, would violate any of the provisions of Section 2.14
(Special Provisions Governing Eurodollar Rate Loans). If, within the time period
required under the terms of this Section 2.11, the Administrative Agent does not
receive a Notice of Conversion or Continuation from the applicable Borrower
containing a permitted election to continue any Eurodollar Rate Loans for an
additional Interest Period or to convert any such Loans, then, upon the
expiration of the applicable Interest Period, such Loans shall be automatically
converted to Base Rate Loans. Each Notice of Conversion or Continuation shall be
irrevocable.

                  SECTION 2.12 FEES

                  (a) Unused Commitment Fee. The Borrowers, jointly and
severally, agree to pay to each Lender from the Initial Closing Date until the
Revolving Credit Termination Date a commitment fee (the "Unused Commitment Fee")
payable in arrears (x) on the last Business Day of each calendar month,
commencing on the first such Business Day following the Initial Closing Date and
(y) on the Revolving Credit Termination Date and, in each case, calculated daily
to equal the following:

                           (i)      if the aggregate Unused Commitments of all
         Lenders does not exceed $50,000,000, 0.5% per annum of such Lender's
         Unused Commitment; and

                           (ii)     if the aggregate Unused Commitments of all
         Lenders exceeds $50,000,000, then the sum of (A) such Lender's Unused
         Ratable Portion of an amount equal to 0.5% per annum of $50,000,000 and
         (B) such Lender's Unused Ratable Portion of an amount equal to 1% per
         annum of the excess of the aggregate Unused Commitments of all Lenders
         over $50,000,000.

                  (b) Letter of Credit Fees. Each Borrower agrees to pay the
following amounts with respect to Letters of Credit issued by any Issuer for its
account:

                           (i)      to the Administrative Agent for the account
         of each Issuer of a Letter of Credit issued for the account of such
         Borrower, with respect to each such Letter of Credit issued by such
         Issuer, an issuance fee equal to 0.25% per annum of the maximum amount
         available from time to time to be drawn under such Letter of Credit,
         payable in arrears (A) on the last Business Day of each calendar month,
         commencing on the first such Business Day following the issuance of
         such Letter of Credit and (B) on the Revolving Credit Termination Date;

                           (ii)     to the Administrative Agent for the ratable
         benefit of the Lenders, with respect to each Letter of Credit issued
         for the account of such Borrower, a fee accruing at a rate per annum
         equal to the Applicable Margin for Revolving Loans that are Eurodollar
         Rate Loans on the maximum amount available from time to time to be
         drawn under such Letter of Credit, payable in arrears (A) on the last
         Business Day of each calendar month, commencing on the first such
         Business Day following the issuance of such Letter of Credit and (B) on
         the Revolving Credit Termination Date; provided, however, that, except
         as otherwise agreed by the Requisite Lenders, during the continuance of
         an Event of Default, such fee shall be increased by two percent per
         annum and shall be payable on demand; and

                           (iii)    to the Issuer of any Letter of Credit, with
         respect to the issuance, amendment or transfer of each Letter of Credit
         and each drawing made thereunder, documentary and processing charges in
         accordance with such Issuer's standard schedule for such charges in
         effect at the time of issuance, amendment, transfer or drawing, as the
         case may be.

                  (c) Additional Fees. The Company has agreed to pay to CUSA,
the Administrative Agent and the Arranger additional fees, the amount and dates
of payment of which are embodied in the Fee Letter.

                  SECTION 2.13 PAYMENTS AND COMPUTATIONS

                  (a) Each Borrower shall make each payment hereunder (including
fees and expenses) not later than 11:00 A.M. (New York City time) on the day
when due, in Dollars, to the Administrative Agent at its address referred to in
Section 11.8 (Notices, Etc.) in immediately available funds without set-off or
counterclaim. The Administrative Agent shall promptly thereafter cause to be
distributed immediately available funds relating to the payment of principal or
interest or fees to the Lenders, in accordance with the application of payments
set forth in clauses (e) and (f) below, as applicable, for the account of their
respective Applicable Lending Offices; provided, however, that amounts payable
pursuant to Section 2.15 (Capital Adequacy), Section 2.16 (Taxes) or clause (c)
or (d) of Section 2.14 (Special Provisions Governing Eurodollar Rate Loans)
shall be paid only to the affected Lender or Lenders and amounts payable with
respect to Swing Loans shall be paid only to the Swing Loan Lender. Payments
received by the Administrative Agent after 11:00 A.M. (New York City time) shall
be deemed to be received on the next Business Day.

                  (b) All computations of interest and of fees shall be made by
the Administrative Agent on the basis of a year of 360 days, in each case for
the actual number of days (including the

                                       49
<PAGE>

                                           AMENDED AND RESTATED CREDIT AGREEMENT

first day but excluding the last day) occurring in the period for which such
interest and fees are payable. Each determination by the Administrative Agent of
an interest rate hereunder shall be conclusive and binding for all purposes,
absent manifest error.

                  (c) Whenever any payment hereunder shall be stated to be due
on a day other than a Business Day, such payment shall be made on the next
succeeding Business Day, and such extension of time shall in such case be
included in the computation of payment of interest or fees, as the case may be;
provided, however, that if such extension would cause payment of interest on any
Eurodollar Rate Loan to be made in the next calendar month, such payment shall
be made on the immediately preceding Business Day. All repayments of any
Revolving Loan shall be applied as follows: first, to repay such Loans
outstanding as Base Rate Loans; and then, to repay such Loans outstanding as
Eurodollar Rate Loans with those Eurodollar Rate Loans that have earlier
expiring Eurodollar Interest Periods being repaid prior to those that have later
expiring Eurodollar Interest Periods.

                  (d) Unless the Administrative Agent shall have received notice
from the Company to the Lenders prior to the date on which any payment is due
hereunder that the applicable Borrower will not make such payment in full, the
Administrative Agent may assume that such Borrower has made such payment in full
to the Administrative Agent on such date and the Administrative Agent may, in
reliance upon such assumption, cause to be distributed to each Lender on such
due date an amount equal to the amount then due such Lender. If and to the
extent that such Borrower shall not have made such payment in full to the
Administrative Agent, each Lender shall repay to the Administrative Agent
forthwith on demand such amount distributed to such Lender together with
interest thereon (at the Federal Funds Rate for the first Business Day and
thereafter at the rate applicable to Base Rate Loans) for each day from the date
such amount is distributed to such Lender until the date such Lender repays such
amount to the Administrative Agent.

                  (e) Subject to the provisions of clause (f) below (and except
as otherwise provided in Section 2.9 (Mandatory Prepayments)), all payments and
any other amounts received by the Administrative Agent from or for the benefit
of any Borrower shall be applied as follows: first, to pay principal of and
interest on any portion of the Loans that the Administrative Agent may have
advanced pursuant to the express provisions of this Agreement on behalf of any
Lender, for which the Administrative Agent has not then been reimbursed by such
Lender or any Borrower; second, to pay all other Obligations then due and
payable; and then, as the Company so designates. Payments in respect of Swing
Loans received by the Administrative Agent shall be distributed to the Swing
Loan Lender; payments in respect of Revolving Loans received by the
Administrative Agent shall be distributed to each Lender in accordance with such
Lender's Ratable Portion; and all payments of fees and all other payments in
respect of any other Obligation shall be allocated among such of the Lenders and
Issuers as are entitled thereto and, for such payments allocated to the Lenders,
in proportion to their respective Ratable Portions.

                  (f) Each Borrower hereby irrevocably waives the right to
direct the application of any and all payments in respect of the Obligations and
any proceeds of Collateral after the occurrence and during the continuance of an
Event of Default and agrees that the Administrative Agent may, and, upon either
(A) the written direction of the Requisite Lenders or (B) the acceleration of
the Obligations pursuant to Section 9.2 (Remedies), shall, apply all payments in
respect of any Obligations and all funds on deposit in any Cash Collateral
Account (including all proceeds arising from a Reinvestment Event that are held
in the Cash Collateral Account pending

application of such proceeds as specified in a Reinvestment Notice) and all
other proceeds of Collateral in the following order:

                           (i)      first, to pay interest on and then principal
         of any portion of the Revolving Loans that the Administrative Agent may
         have advanced on behalf of any Lender for which the Administrative
         Agent has not then been reimbursed by such Lender or any Borrower;

                           (ii)     second, to pay interest on and then
         principal of any Swing Loan;

                           (iii)    third, to pay Obligations in respect of any
         expense reimbursements or indemnities then due to the Administrative
         Agent;

                           (iv)     fourth, to pay Obligations in respect of any
         expense reimbursements or indemnities then due to the Lenders and the
         Issuers;

                           (v)      fifth, to pay Obligations in respect of any
         fees then due to the Administrative Agent, the Lenders and the Issuers;

                           (vi)     sixth, to pay interest then due and payable
         in respect of the Loans and Reimbursement Obligations;

                           (vii)    seventh, to pay or prepay principal payments
         on the Loans and Reimbursement Obligations and to provide cash
         collateral for outstanding Letter of Credit Undrawn Amounts in the
         manner described in Section 9.3 (Actions in Respect of Letters of
         Credit), ratably to the aggregate principal amount of such Loans,
         Reimbursement Obligations and Letter of Credit Undrawn Amounts; and

                           (viii)   eighth, to the ratable payment of all other
         Obligations;

provided, however, that if sufficient funds are not available to fund all
payments to be made in respect of any of the Obligations described in any of
clauses first through eighth above, the available funds being applied with
respect to any such Obligation (unless otherwise specified in such clause) shall
be allocated to the payment of such Obligations ratably, based on the proportion
of the Administrative Agent's and each Lender's or Issuer's interest in the
aggregate outstanding Obligations described in such clauses. The order of
priority set forth in clauses first through eighth above may at any time and
from time to time be changed by the agreement of the Requisite Lenders without
necessity of notice to or consent of or approval by any Borrower, any Secured
Party that is not a Lender or Issuer or by any other Person that is not a Lender
or Issuer. The order of priority set forth in clauses first through fifth above
may be changed only with the prior written consent of the Administrative Agent
in addition to the Requisite Lenders.

                  (g) At the option of the Administrative Agent, principal on
the Swing Loans, Reimbursement Obligations, interest, fees, expenses and other
sums due and payable in respect of the Revolving Loans and Protective Advances
may be paid from the proceeds of Swing Loans or Revolving Loans. Each Borrower
hereby authorizes the Swing Loan Lender to make Swing Loans pursuant to Section
2.3(a) (Swing Loans) and the Lenders to make Revolving Loans pursuant to Section
2.2(a) (Borrowing Procedures) from time to time in the Swing Loan Lender's or
such Lender's discretion, that are in the amounts of any and all principal
payable with respect to the Swing Loans and interest, fees, expenses and other
sums payable in respect of the

Revolving Loans, and further authorizes the Administrative Agent to give the
Lenders notice of any Borrowing with respect to such Swing Loans and Revolving
Loans and to distribute the proceeds of such Swing Loans and Revolving Loans to
pay such amounts. Each Borrower agrees that all such Swing Loans and Revolving
Loans so made shall be deemed to have been requested by it (irrespective of the
satisfaction of the conditions in Section 3.2 (Conditions Precedent to Each Loan
and Letter of Credit), which conditions the Lenders irrevocably waive) and
directs that all proceeds thereof shall be used to pay such amounts.

                  SECTION 2.14 SPECIAL PROVISIONS GOVERNING EURODOLLAR RATE
LOANS

                  (a) Determination of Interest Rate

                  The Eurodollar Rate for each Interest Period for Eurodollar
Rate Loans shall be determined by the Administrative Agent pursuant to the
procedures set forth in the definition of "Eurodollar Rate." The Administrative
Agent's determination shall be presumed to be correct absent manifest error and
shall be binding on the Borrowers.

                  (b) Interest Rate Unascertainable, Inadequate or Unfair

                  In the event that: (i) the Administrative Agent determines
that adequate and fair means do not exist for ascertaining the applicable
interest rates by reference to which the Eurodollar Rate then being determined
is to be fixed or (ii) the Requisite Lenders notify the Administrative Agent
that the Eurodollar Rate for any Interest Period will not adequately reflect the
cost to the Lenders of making or maintaining such Loans for such Interest
Period, the Administrative Agent shall forthwith so notify the Company and the
Lenders, whereupon each Eurodollar Loan shall automatically, on the last day of
the current Interest Period for such Loan, convert into a Base Rate Loan and the
obligations of the Lenders to make Eurodollar Rate Loans or to convert Base Rate
Loans into Eurodollar Rate Loans shall be suspended until the Administrative
Agent shall notify the Company that the Requisite Lenders have determined that
the circumstances causing such suspension no longer exist.

                  (c) Increased Costs

                  If at any time any Lender shall determine that, after the
Initial Closing Date, because of the introduction of or any change in or in the
interpretation of any law, treaty or governmental rule, regulation or order
(other than any change by way of imposition or increase of reserve requirements
included in determining the Eurodollar Rate) or the compliance by such Lender
with any guideline, request or directive promulgated or given after the Initial
Closing Date by or on behalf of any central bank or other Governmental Authority
(whether or not having the force of law), there shall be any increase in the
cost to such Lender of agreeing to make or making, funding or maintaining any
Eurodollar Rate Loans, then the Borrowers shall from time to time, upon demand
by such Lender (with a copy of such demand to the Administrative Agent), pay,
jointly and severally, to the Administrative Agent for the account of such
Lender additional amounts sufficient to compensate such Lender for such
increased cost; provided, however, that no Borrower shall be liable for
increased costs relating to periods up to but excluding the date 180 days before
the initial demand is made hereunder by such Lender with respect to the change
that would otherwise justify such liability. If any Lender becomes entitled to
claim any additional amount pursuant to this clause (c), it shall promptly
notify the Company (with a copy to the Administrative Agent) of the event by
reason of which it has become so entitled. A certificate as to the amount of
such increased cost, submitted to the Company and the Administrative Agent by
such Lender, shall be conclusive and binding for all purposes, absent manifest
error.

                  (d) Illegality

                  Notwithstanding any other provision of this Agreement, if any
Lender determines that the introduction of or any change in or in the
interpretation of any law, treaty or governmental rule, regulation or order
after the date of this Agreement shall make it unlawful, or any central bank or
other Governmental Authority shall assert that it is unlawful, for any Lender or
its Eurodollar Lending Office to make Eurodollar Rate Loans or to continue to
fund or maintain Eurodollar Rate Loans, then, on notice thereof and demand
therefor by such Lender to the Company through the Administrative Agent, (i) the
obligation of such Lender to make or to continue Eurodollar Rate Loans and to
convert Base Rate Loans into Eurodollar Rate Loans shall be suspended, and each
such Lender shall make a Base Rate Loan as part of any requested Borrowing of
Eurodollar Rate Loans and (ii) if the affected Eurodollar Rate Loans are then
outstanding, the applicable Borrower shall immediately convert each such Loan
into a Base Rate Loan. If at any time after a Lender gives notice under this
clause (d) such Lender determines that it may lawfully make Eurodollar Rate
Loans, such Lender shall promptly give notice of that determination to the
Company and the Administrative Agent, and the Administrative Agent shall
promptly transmit the notice to each other Lender. The Borrowers' right to
request, and such Lender's obligation, if any, to make Eurodollar Rate Loans
shall thereupon be restored.

                  (e) Breakage Costs

                  In addition to all amounts required to be paid by any Borrower
pursuant to Section 2.10 (Interest), each Borrower shall compensate each Lender,
upon demand, for all losses, expenses and liabilities (including any loss or
expense incurred by reason of the liquidation or reemployment of deposits or
other funds acquired by such Lender to fund or maintain such Lender's Eurodollar
Rate Loans to such Borrower but excluding any loss of the Applicable Margin on
the relevant Loans) that such Lender may sustain (i) if for any reason a
proposed Borrowing, conversion into or continuation of Eurodollar Rate Loans
does not occur on a date specified therefor in a Notice of Borrowing or a Notice
of Conversion or Continuation given by such Borrower or in a telephonic request
by it for borrowing or conversion or continuation or a successive Interest
Period does not commence after notice therefor is given pursuant to Section 2.11
(Conversion/Continuation Option), (ii) if for any reason any Eurodollar Rate
Loan is prepaid (including mandatorily pursuant to Section 2.9 (Mandatory
Prepayments)) on a date that is not the last day of the applicable Interest
Period, (iii) as a consequence of a required conversion of a Eurodollar Rate
Loan to a Base Rate Loan as a result of any of the events indicated in clause
(d) above or (iv) as a consequence of any failure by such Borrower to repay
Eurodollar Rate Loans when required by the terms hereof. The Lender making
demand for such compensation shall deliver to the Company concurrently with such
demand a written statement as to such losses, expenses and liabilities, and this
statement shall be conclusive as to the amount of compensation due to that
Lender, absent manifest error.

                  SECTION 2.15 CAPITAL ADEQUACY

                  If at any time any Lender determines that (a) the adoption of
or any change in or in the interpretation of any law, treaty or governmental
rule, regulation or order after the date of this Agreement regarding capital
adequacy, (b) compliance with any such law, treaty, rule, regulation or order or
(c) compliance with any guideline or request or directive from any central bank
or other Governmental Authority (whether or not having the force of law) shall
have the effect of reducing the rate of return on such Lender's (or any
corporation controlling such Lender's) capital as a consequence of its
obligations hereunder or under or in respect of any

                                           AMENDED AND RESTATED CREDIT AGREEMENT
                                                             SUNTRON CORPORATION

Letter of Credit to a level below the level that such Lender or such corporation
could have achieved but for such adoption, change, compliance or interpretation,
then, upon demand from time to time by such Lender (with a copy of such demand
to the Administrative Agent), the Borrowers, jointly and severally, agree that
they shall pay to the Administrative Agent for the account of such Lender, from
time to time as specified by such Lender, additional amounts sufficient to
compensate such Lender for such reduction; provided, however, that no Borrower
shall be liable for reductions in rates of return relating to periods up to but
excluding the date 180 days before the initial demand is made hereunder by such
Lender with respect to the event in clauses (a), (b) or (c) above relating to
such reduction. A certificate as to such amounts submitted to the Company and
the Administrative Agent by such Lender shall be conclusive and binding for all
purposes absent manifest error.

                  SECTION 2.16 TAXES

                  (a) Any and all payments by any Borrower under each Loan
Document shall be made free and clear of and without deduction for any and all
present or future taxes, levies, imposts, deductions, charges or withholdings,
and all liabilities with respect thereto, excluding (i) in the case of each
Lender and the Administrative Agent (A) taxes measured by its net income
(including branch profits tax, alternative minimum tax and other taxes imposed
in lieu of net income tax), and franchise taxes imposed on it, by the
jurisdiction (or any political subdivision thereof) under the laws of which such
Lender or the Administrative Agent (as the case may be) is organized or in which
it is engaged in business and (B) any United States withholding taxes payable
with respect to payments under the Loan Documents under laws (including any
statute, treaty or regulation) in effect on the Initial Closing Date (or, in the
case of an Eligible Assignee, the date of the Assignment and Acceptance)
applicable to such Lender or the Administrative Agent, as the case may be, but
not excluding any United States withholding payable as a result of any change in
such laws occurring after the Initial Closing Date (or the date of such
Assignment and Acceptance) and (C) Taxes resulting from the failure of any
Non-U.S. Lender to comply with clause (f) of this Section 2.16 and (ii) in the
case of each Lender, taxes measured by its net income (including branch profits
tax, alternative minimum tax and other taxes imposed in lieu of net income tax),
and franchise taxes imposed on it, by the jurisdiction in which such Lender's
Applicable Lending Office is located or in which it is engaged in business (all
such non-excluded taxes, levies, imposts, deductions, charges, withholdings and
liabilities being hereinafter referred to as "Taxes"). If any Taxes shall be
required by law to be deducted from or in respect of any sum payable under any
Loan Document to any Lender or the Administrative Agent (w) the sum payable
shall be increased as may be necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section 2.16) such Lender or the Administrative Agent (as the case may be)
receives an amount equal to the sum it would have received had no such
deductions been made, (x) the relevant Borrower shall make such deductions, (y)
the Borrowers shall pay the full amount deducted to the relevant taxing
authority or other authority in accordance with applicable law and (z) the
Borrowers shall deliver to the Administrative Agent evidence of such payment.

                  (b) In addition, the Borrowers hereby, jointly and severally,
agree to pay any present or future stamp or documentary taxes or any other
excise taxes, charges or similar levies of the United States or any political
subdivision thereof or any applicable foreign jurisdiction, and all liabilities
with respect thereto, arising from any payment made under any Loan Document or
from the execution, delivery or registration of, or otherwise with respect to,
any Loan Document (collectively, "Other Taxes").

                                           AMENDED AND RESTATED CREDIT AGREEMENT
                                                             SUNTRON CORPORATION

                  (c) The Borrowers hereby, jointly and severally, agree to
indemnify each Lender and the Administrative Agent for the full amount of Taxes
and Other Taxes (including any Taxes or Other Taxes imposed by any jurisdiction
on amounts payable under this Section 2.16) paid by such Lender or the
Administrative Agent (as the case may be) and any liability (including for
penalties, interest and expenses) arising therefrom or with respect thereto
other than any such liabilities attributable to any gross negligence of such
Lender or, as the case may be, the Administrative Agent. This indemnification
shall be made within 30 days from the date such Lender or the Administrative
Agent (as the case may be) makes written demand therefor.

                  (d) Within 30 days after the date of any payment of Taxes or
Other Taxes, the Borrowers shall furnish to the Administrative Agent, at its
address referred to in Section 11.8 (Notices, Etc.), the original or a certified
copy of a receipt evidencing payment thereof (or, if such original or certified
copy is not available, any other proof of payment reasonably satisfactory to the
Administrative Agent).

                  (e) Without prejudice to the survival of any other agreement
of any Borrower hereunder, the agreements and obligations of the Borrowers
contained in this Section 2.16 shall survive the payment in full of the
Obligations.

                  (f) Prior to the Effective Date in the case of each Non-U.S.
Lender that is a signatory hereto, and on the date of the Assignment and
Acceptance pursuant to which it becomes a Lender in the case of each other
Non-U.S. Lender and from time to time thereafter if requested by the Company or
the Administrative Agent, each Non-U.S. Lender that is entitled at such time to
an exemption from United States withholding tax, or that is subject to such tax
at a reduced rate under an applicable tax treaty, shall provide the
Administrative Agent and the Company with two completed copies of (i) Form
W-8ECI (claiming exemption from withholding because the income is effectively
connected with a U.S. trade or business) or any successor form, (ii) Form W-8BEN
(claiming exemption from, or a reduction of, withholding tax under an income tax
treaty) or any successor form, (iii) in the case of a Non-U.S. Lender claiming
exemption under Sections 871(h) or 881(c) of the Code, a Form W-8BEN (claiming
exemption from withholding under the portfolio interest exemption) or any
successor form, together with a certificate satisfactory to the Borrower and the
Administrative Agent executed by such Non-U.S. Lender stating that it meets all
conditions for the portfolio interest exemption, including the statement as to
its non-bank status or (iv) or any other applicable form, certificate or
document prescribed by the IRS certifying as to such Non-U.S. Lender's
entitlement to such exemption from United States withholding tax or reduced rate
with respect to all payments to be made to such Non-U.S. Lender under the Loan
Documents. Unless the Company and the Administrative Agent have received forms
or other documents satisfactory to them indicating that payments under any Loan
Document to or for a Non-U.S. Lender are not subject to United States
withholding tax or are subject to such tax at a rate reduced by an applicable
tax treaty, the Borrowers or the Administrative Agent shall withhold taxes from
such payments at the applicable statutory rate.

                  (g) Any Lender claiming any additional amounts payable
pursuant to this Section 2.16 shall use its reasonable efforts (consistent with
its internal policy and legal and regulatory restrictions) to change the
jurisdiction of its Applicable Lending Office if the making of such a change
would avoid the need for, or reduce the amount of, any such additional amounts
that would be payable or may thereafter accrue and would not, in the sole
determination of such Lender, be otherwise disadvantageous to such Lender.

                                           AMENDED AND RESTATED CREDIT AGREEMENT
                                                             SUNTRON CORPORATION

                  (h) If any Lender receives a refund or credit against its tax
that, in the reasonable judgment of the Lender, is attributable to the
additional amount paid by the Borrower under this Section 2.16, such Lender
shall promptly pay to the Borrower the amount of such refund or credit.

                  (i) Each Lender selling participations relating to the Loan
Document shall be responsible for complying with any registration requirement
and withholding requirement (including the receipt of any applicable forms,
certificates and documents) as they relate to such participations, pursuant to
the Code and the regulations thereunder.

                  SECTION 2.17 SUBSTITUTION OF LENDERS

                  In the event that (a) (i) any Lender makes a claim under
Section 2.14(c) (Increased Costs) or Section 2.15 (Capital Adequacy), (ii) it
becomes illegal for any Lender to continue to fund or make any Eurodollar Rate
Loan and such Lender notifies the Company pursuant to Section 2.14(d)
(Illegality) or Section 2.15 (Capital Adequacy) or (iii) any Borrower is
required to make any payment pursuant to Section 2.16 (Taxes), that is
attributable to any Lender, or any Lender is a Non-Funding Lender, (b) in the
case of subclause (a)(i) above, as a consequence of increased costs in respect
of which such claim is made, the effective rate of interest payable to such
Lender under this Agreement with respect to its Loans materially exceeds the
effective average annual rate of interest payable to the Requisite Lenders under
this Agreement and (c) Lenders holding at least 75% of the Revolving Credit
Commitments are not subject to such increased costs or illegality, payment or
proceedings (any such Lender, an "Affected Lender"), the Company may substitute
another financial institution for such Affected Lender hereunder, upon
reasonable prior written notice (which written notice must be given within 90
days following the occurrence of any of the events described in subclauses
(a)(i), (ii), (iii) or (iv) above) by the Company to the Administrative Agent
and the Affected Lender that the Company intends to make such substitution,
which substitute financial institution must be an Eligible Assignee and, if not
a Lender, reasonably acceptable to the Administrative Agent; provided, however,
that if more than one Lender claims increased costs, illegality or right to
payment arising from the same act or condition and such claims are received by
the Company within 30 days of each other then the Company may substitute all,
but not (except to the extent the Company has already substituted one of such
Affected Lenders before the Company's receipt of the other Affected Lenders'
claim) less than all, Lenders making such claims. In the event that the proposed
substitute financial institution or other entity is reasonably acceptable to the
Administrative Agent and the written notice was properly issued under this
Section 2.17, the Affected Lender shall sell and the substitute financial
institution or other entity shall purchase, pursuant to an Assignment and
Acceptance, all rights and claims of such Affected Lender under the Loan
Documents and the substitute financial institution or other entity shall assume
and the Affected Lender shall be relieved of its Revolving Credit Commitments
and all other prior unperformed obligations of the Affected Lender under the
Loan Documents (other than in respect of any damages (other than exemplary or
punitive damages, to the extent permitted by applicable law) in respect of any
such unperformed obligations). Upon the effectiveness of such sale, purchase and
assumption (that, in any event, shall be conditioned upon the payment in full by
the Borrowers to the Affected Lender in cash of all fees, unreimbursed costs and
expenses and indemnities accrued and unpaid through such effective date), the
substitute financial institution or other entity shall become a "Lender"
hereunder for all purposes of this Agreement having a Revolving Credit
Commitment in the amount of such Affected Lender's Revolving Credit Commitment
assumed by it and such Revolving Credit Commitment of the Affected Lender shall

be terminated, provided, however, that all indemnities under the Loan Documents
shall continue in favor of such Affected Lender.

Borrowing Base of such Borrower and its Eligible Subsidiaries is less than 90%
of the Borrowing Base of such Borrower and its Eligible Subsidiaries reflected
in the most recent Borrowing Base Certificate for such Borrower delivered
pursuant to clause (a) above or (ii) the outstanding Revolving Credit
Outstandings owing by such Borrower exceed the Borrowing Base for such Borrower
and its Eligible Subsidiaries as a result of a decrease therein, in which case
such notice shall also include, without limitation, the amount of such excess.

                  (d) The Administrative Agent may, at the Borrowers' sole cost
and expense, make test verifications of the Accounts and physical verifications
of the Inventory in any manner and through any medium that the Administrative
Agent considers advisable, and each Borrower shall furnish all such assistance
and information as the Administrative Agent may require in connection therewith.

Equipment shall be determined using the valuations set forth in the appraisal
dated as of April 1, 2003, by Emerald Technology Valuations, LLC and (ii) the

                  (f) The values determined in clause (e) above shall be updated

anniversary of the Effective Date, based on new appraisals obtained by the
Borrowers at their own expense in form and substance and from an appraiser
reasonably acceptable to the Administrative Agent, (ii) in the case of Eligible
Real Property, at least annually, based on new appraisals obtained by the
Borrowers at their own expense in form and substance and from an appraiser
reasonably acceptable to the Administrative Agent. If any Eligible Equipment is
sold by any Borrower or Eligible Subsidiary thereof in accordance with clause
(b) of Section 8.4 (Sale of Assets), then, the orderly liquidation value of the
remaining Eligible Equipment shall be determined (until the next appraisal,
investigation, "desktop review" or other review conducted in accordance with
this Agreement in respect of such Eligible Equipment) by subtracting from the
orderly liquidation value of the Eligible Equipment of such Borrower or Eligible
Subsidiary prior to such sale the Net Cash Proceeds of such sale used to prepay
the Loans in accordance with clause (a) of Section 2.9 (Mandatory Prepayments).

                  (g) In addition, the Administrative Agent may conduct (or ask
the Borrowers to conduct at their own expense and with a third-party appraiser

                  SECTION 9.2 REMEDIES

                  During the continuance of any Event of Default, the
Administrative Agent (a) may, and, at the request of the Requisite Lenders,
shall, by notice to any Borrower declare that all of the Revolving Credit
Commitments be terminated, whereupon the obligation of each Lender to make any
Loan and each Issuer to issue any Letter of Credit shall immediately terminate
and (b) may and shall at the request of the Requisite Lenders, by notice to any
Borrower, declare the Loans, all interest thereon and all other amounts and
Obligations payable under this Agreement to be forthwith due and payable,
whereupon the Loans, all such interest and all such amounts and Obligations
shall become and be forthwith due and payable, without presentment, demand,
protest or further notice of any kind, all of which are hereby expressly waived
by each Borrower; provided, however, that upon the occurrence of the Events of
Default specified in Section 9.1(f) (Events of Default), (A) (i) the Revolving
Credit Commitments of each Lender to make Loans and of each Lender and Issuer to
issue or participate in Letters of Credit shall automatically be terminated and
(ii) the Loans, all such interest and all such amounts and Obligations shall
automatically become and be due and payable, without presentment, demand,
protest or any notice of any kind, all of which are hereby expressly waived by
each Borrower. In addition to the remedies set forth above, the Administrative
Agent may exercise any remedies provided for by the Collateral Documents in
accordance with the terms thereof or any other remedies provided by applicable
law.

                  SECTION 9.3 ACTIONS IN RESPECT OF LETTERS OF CREDIT

                  Upon the Revolving Credit Termination Date or as required by

funds at the Administrative Agent's office referred to in Section 11.8 (Notices,
Etc.), for deposit in a Cash Collateral Account, an amount equal to 105% of the

apply funds then held in such Cash Collateral Account to the payment of any
amounts, in accordance with Section 2.13(f) (Payments and Computations), as
shall have become or shall become due and payable by any Borrower to the Issuers
or Lenders in respect of the Letter of Credit Obligations. The Administrative
Agent shall promptly give written notice of any such application; provided,
however, that the failure to give such written notice shall not invalidate any
such application.

                  SECTION 9.4 RESCISSION

                  If at any time after termination of the Revolving Credit
Commitments or acceleration of the maturity of the Loans, the Borrowers shall
pay, jointly and severally, all arrears of interest and all payments on account
of principal of the Loans and Reimbursement Obligations that shall have become
due otherwise than by acceleration (with interest on principal and, to the
extent permitted by law, on overdue interest, at the rates specified herein) and
all Events of Default and Defaults (other than non-payment of principal of and
accrued interest on the Loans due and payable solely by virtue of acceleration)
shall be remedied or waived pursuant Section 11.1 (Amendments, Waivers, Etc.),
then upon the written consent of the Requisite Lenders and written notice to any

acceleration and their consequences may be rescinded and annulled; but such
action shall not affect any subsequent Event of Default or Default or impair any
right or remedy consequent thereon. The provisions of the preceding sentence are
intended merely to bind the Lenders and the Issuers to a decision that may be
made at the election of the Requisite Lenders; they are not intended to benefit
any Loan Party and do not give any Loan Party the right to require the Lenders
to rescind or annul any acceleration hereunder, even if the conditions set forth
herein are met.

                      THE ADMINISTRATIVE AGENT; THE AGENTS

                  SECTION 10.1 AUTHORIZATION AND ACTION

                  (a) Each Lender and each Issuer hereby appoints CUSA as the
Administrative Agent hereunder and each Lender and each Issuer authorizes the
Administrative Agent to take such action as agent on its behalf and to exercise
such powers under this Agreement and the other Loan Documents as are delegated
to the Administrative Agent under such agreements and to exercise such powers as
are reasonably incidental thereto. Without limiting the foregoing, each Lender
and each Issuer hereby authorizes the Administrative Agent to execute and
deliver, and to perform its obligations under, each of the Loan Documents to
which the Administrative Agent is a party and to exercise all rights, powers and
remedies that the Administrative Agent may have under such Loan Documents and
that under the Collateral Documents the Administrative Agent is acting as agent
for the Lenders, Issuers and the other Secured Parties.

                  (b) As to any matters not expressly provided for by this
Agreement and the other Loan Documents (including enforcement or collection),
the Administrative Agent shall not be required to exercise any discretion or
take any action, but shall be required to act or to refrain from acting (and
shall be fully protected in so acting or refraining from acting) upon the
instructions of the Requisite Lenders, and such instructions shall be binding
upon all Lenders and each Issuer; provided, however, that the Administrative
Agent shall not be required to take any action that (i) the Administrative Agent
in good faith believes exposes it to personal liability unless the
Administrative Agent receives an indemnification satisfactory to it from the
Lenders and the Issuers with respect to such action or (ii) is contrary to this
Agreement or applicable law. The Administrative Agent agrees to give to each
Lender and each Issuer prompt notice of each notice given to it by any Loan
Party pursuant to the terms of this Agreement or the other Loan Documents.

                  (c) In performing its functions and duties hereunder and under
the other Loan Documents, the Administrative Agent is acting solely on behalf of
the Lenders and the Issuers and its duties are entirely administrative in
nature. The Administrative Agent does not assume and shall not be deemed to have
assumed any obligation other than as expressly set forth herein and in the other
Loan Documents or any other relationship as the agent, fiduciary or trustee of
or for any Lender, Issuer or holder of any other Obligation. The Administrative
Agent may perform any of its duties under any of the Loan Documents by or
through its agents or employees.

                  SECTION 10.2 ADMINISTRATIVE AGENT'S RELIANCE, ETC.

                  Neither the Administrative Agent nor any of its Affiliates or
any of the respective directors, officers, agents or employees of the
Administrative Agent or any such Affiliate shall be liable for any action taken
or omitted to be taken by it, him, her or them under or in connection with this
Agreement or the other Loan Documents, except for its, his, her or their own
gross negligence or willful misconduct. Without limiting the foregoing, the
Administrative Agent (a) may treat the payee of any Revolving Credit Note as its
holder until such Revolving Credit Note has been assigned in accordance with
Section 11.2 (Assignments and Participations), (b) may rely on the Register to
the extent set forth in Section 11.2(c) (Assignments and Participations), (c)
may consult with legal counsel (including counsel to the Company or any other
Loan Party), independent public accountants and other experts selected by it and
shall not be liable for any action taken or omitted to be taken in good faith by
it in accordance with the advice of such counsel, accountants or experts, (d)
makes no warranty or representation to any Lender or Issuer and shall not be
responsible to any Lender or Issuer for any statements, warranties or
representations made by or on behalf of any Borrower or any Subsidiary thereof
in or in connection with this Agreement or any of the other Loan Documents, (e)
shall not have any duty to ascertain or to inquire either as to the performance
or observance of any of the terms, covenants or conditions of this Agreement or
any of the other Loan Documents or the financial condition of any Loan Party, or
the existence or possible existence of any Default or Event of Default, (f)
shall not be responsible to any Lender or Issuer for the due execution,
legality, validity, enforceability, genuineness, sufficiency or value of, or the
attachment, perfection or priority of any Lien created or purported to be
created under or in connection with, this Agreement or any of the other Loan
Documents or any other instrument or document furnished pursuant hereto or
thereto and (g) shall incur no liability under or in respect of this Agreement
or any of the other Loan Documents by acting upon any notice, consent,
certificate or other instrument or writing (which writing may be a telecopy or
electronic mail) or any telephone message believed by it to be genuine and
signed or sent by the proper party or parties.

                  SECTION 10.3 POSTING OF APPROVED ELECTRONIC COMMUNICATIONS

                  (a) Each of the Lenders, the Issuers and the Company and each
Borrower agrees, and the Company and each Borrower shall cause each Subsidiary
Guarantor to agree, that the Administrative Agent may, but shall not be
obligated to, make the Approved Electronic Communications available to the
Lenders and Issuers by posting such Approved Electronic Communications on
"e-Disclosure", the Administrative Agent's internet delivery system that is part
of SSB Direct, Global Fixed Income's primary web portal, or successor electronic
platform chosen by the Administrative Agent to be its internet delivery system
(the "Approved Electronic Platform").

                  (b) Although the primary web portal is secured with a dual
firewall and a User ID/Password Authorization System and the Approved Electronic
Platform is secured through a single-user-per-deal authorization method whereby
each user may access the Approved Electronic Platform only on a deal-by-deal
basis, each of the Lenders, the Issuers, the Company and each Borrower
acknowledges and agrees, that the distribution of material through an electronic
medium is not necessarily secure and that there are confidentiality and other
risks associated with such distribution. In consideration for the convenience
and other benefits afforded by such distribution and for the other consideration
provided hereunder, the receipt and sufficiency of which is hereby acknowledged,
each of the Lenders, the Issuers, the Company and each Borrower hereby approves,
distribution of the Approved Electronic Communications

through the Approved Electronic Platform and understands and assumes, and the
Borrower shall cause each Subsidiary Guarantor to understand and assume, the
risks of such distribution.

                  (c) The Approved Electronic Communications and the Approved
Electronic Platform are provided "as is" and "as available". None of the
Administrative Agent or any of its Affiliates or any of their respective
officers, directors, employees, agents, advisors or representatives (the "Agent
Affiliates") warrants the accuracy, adequacy or completeness of the Approved
Electronic Communications and the Approved Electronic Platform and each of them
expressly disclaims liability for errors or omissions in the Approved Electronic
Communications and the Approved Electronic Communications. No warranty of any
kind, express, implied or statutory (including any warranty of merchantability,
fitness for a particular purpose, non-infringement of third party rights or
freedom from viruses or other code defects) is made by the Agent Affiliates in
connection with the Approved Electronic Communications.

                  SECTION 10.4 THE ADMINISTRATIVE AGENT INDIVIDUALLY

                  With respect to its Ratable Portion, CUSA shall have and may
exercise the same rights and powers hereunder and is subject to the same
obligations and liabilities as and to the extent set forth herein for any other
Lender. The terms "Lenders", "Requisite Lenders" and "Supermajority Lenders" and
any similar terms shall, unless the context clearly otherwise indicates,
include, without limitation, the Administrative Agent in its individual capacity
as a Lender or as one of the Requisite Lenders. CUSA and its Affiliates may
accept deposits from, lend money to, and generally engage in any kind of
banking, trust or other business with, any Loan Party as if CUSA were not acting
as the Administrative Agent.

                  SECTION 10.5 LENDER CREDIT DECISION

                  Each Lender and each Issuer acknowledges that it shall,
independently and without reliance upon the Administrative Agent or any other
Lender conduct its own independent investigation of the financial condition and
affairs of each Borrower and each other Loan Party in connection with the making
and continuance of the Loans and with the issuance of the Letters of Credit.
Each Lender and each Issuer also acknowledges that it shall, independently and
without reliance upon the Administrative Agent or any other Lender and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
this Agreement and other Loan Documents.

                  SECTION 10.6 INDEMNIFICATION

                  Each Lender agrees to indemnify the Administrative Agent and
each of its Affiliates, and each of their respective directors, officers,
employees, agents and advisors (to the extent not reimbursed by any Borrower),
from and against such Lender's aggregate Ratable Portion of any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses and disbursements (including fees and disbursements of legal
counsel) of any kind or nature whatsoever that may be imposed on, incurred by,
or asserted against, the Administrative Agent or any of its Affiliates,
directors, officers, employees, agents and advisors in any way relating to or
arising out of this Agreement or the other Loan Documents or any action taken or
omitted by the Administrative Agent under this Agreement or the other Loan
Documents; provided, however, that no Lender shall be liable for any portion of
such liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements resulting from the Administrative
Agent's or such Affiliate's gross negligence or

willful misconduct. Without limiting the foregoing, each Lender agrees to
reimburse the Administrative Agent promptly upon demand for its ratable share of
any out-of-pocket expenses (including fees and disbursements of legal counsel)
incurred by the Administrative Agent in connection with the preparation,
execution, delivery, administration, modification, amendment or enforcement
(whether through negotiations, legal proceedings or otherwise) of, or legal
advice in respect of its rights or responsibilities under, this Agreement or the
other Loan Documents, to the extent that the Administrative Agent is not
reimbursed for such expenses by any Borrower or any other Loan Party.

                  SECTION 10.7 SUCCESSOR ADMINISTRATIVE AGENT

                  The Administrative Agent may resign at any time by giving
written notice thereof to the Lenders and the Company. Upon any such
resignation, the Requisite Lenders shall have the right to appoint a successor
Administrative Agent. If no successor Administrative Agent shall have been so
appointed by the Requisite Lenders, and shall have accepted such appointment,
within 30 days after the retiring Administrative Agent's giving of notice of
resignation, then the retiring Administrative Agent may, on behalf of the
Lenders, appoint a successor Administrative Agent, selected from among the
Lenders. In either case, such appointment shall be subject to the prior written
approval of the Company (which approval may not be unreasonably withheld and
shall not be required upon the occurrence and during the continuance of an Event
of Default). Upon the acceptance of any appointment as Administrative Agent by a
successor Administrative Agent, such successor Administrative Agent shall
succeed to and become vested with all the rights, powers, privileges and duties
of the retiring Administrative Agent, and the retiring Administrative Agent
shall be discharged from its duties and obligations under this Agreement and the
other Loan Documents. Prior to any retiring Administrative Agent's resignation
hereunder as Administrative Agent, the retiring Administrative Agent shall take
such action as may be reasonably necessary to assign to the successor
Administrative Agent its rights as Administrative Agent under the Loan
Documents. After such resignation, the retiring Administrative Agent shall
continue to have the benefit of this Article X as to any actions taken or
omitted to be taken by it while it was Administrative Agent under this Agreement
and the other Loan Documents.

                  SECTION 10.8 CONCERNING THE COLLATERAL AND THE COLLATERAL
DOCUMENTS

                  (a) Each Lender and each Issuer agrees that any action taken
by the Administrative Agent, the Requisite Lenders (or, where required by the
express terms of this Agreement, a greater proportion of the Lenders) in
accordance with the provisions of this Agreement or of the other Loan Documents,
and the exercise by the Administrative Agent, the Requisite Lenders (or, where
so required, such greater proportion) of the powers set forth herein or therein,
together with such other powers as are reasonably incidental thereto, shall be
authorized and binding upon all of the Lenders, Issuers and other Secured
Parties. Without limiting the generality of the foregoing, the Administrative
Agent shall have the sole and exclusive right and authority to (i) act as the
disbursing and collecting agent for the Lenders and the Issuers with respect to
all payments and collections arising in connection herewith and with the
Collateral Documents, (ii) execute and deliver each Collateral Document and
accept delivery of each such agreement delivered by the Borrowers or any of
their Subsidiaries, (iii) act as collateral agent for the Lenders, the Issuers
and the other Secured Parties for purposes of the perfection of all security
interests and Liens created by such agreements and all other purposes stated
therein, provided, however, that the Administrative Agent hereby appoints,
authorizes and directs each Lender and Issuer to act as collateral sub-agent for
the Administrative Agent, the

Lenders and the Issuers for purposes of the perfection of all security interests
and Liens with respect to the Borrowers' and their Subsidiaries' respective
deposit accounts maintained with, and cash and Cash Equivalents held by, such
Lender or such Issuer, (iv) manage, supervise and otherwise deal with the
Collateral, (v) take such action as is necessary or desirable to maintain the
perfection and priority of the security interests and Liens created or purported
to be created by the Collateral Documents and (vi) except as may be otherwise
specifically restricted by the terms hereof or of any other Loan Document,
exercise all remedies given to the Administrative Agent, the Lenders, the
Issuers and the other Secured Parties with respect to the Collateral under the
Loan Documents relating thereto, applicable law or otherwise.

                  (b) Each of the Lenders and the Issuers hereby directs, in
accordance with the terms hereof, the Administrative Agent to release (or, in
the case of clause (ii) below, release or subordinate), and the Administrative
Agent hereby agrees to release, any Lien held by the Administrative Agent for
the benefit of the Lenders and the Issuers:

                           (i)      against all of the Collateral, upon
         termination of the Revolving Credit Commitments and payment and
         satisfaction in full of all Loans, Reimbursement Obligations and all
         other mature Obligations that the Administrative Agent has been
         notified in writing are then due and payable (and, in respect of
         contingent Letter of Credit Obligations, with respect to which cash
         collateral has been deposited or a back-up letter of credit has been
         issued, in either case on terms satisfactory to the Administrative
         Agent and the applicable Issuers);

                           (ii)     against any assets that are subject to a
         Lien permitted by clause (d) or (e) of Section 8.2 (Liens, Etc.); and

                           (iii)    (A) against any part of the Collateral sold
         or disposed of by a Loan Party if such sale or disposition is permitted
         by this Agreement (or permitted pursuant to a waiver or consent of a
         transaction otherwise prohibited by this Agreement), (B) if not
         pursuant to such sale or disposition, against Collateral with a book
         value of up to $1,000,000, if such release is consented to by the
         Administrative Agent, (C) otherwise, against any part of the Collateral
         with a book value in excess of $1,000,000 but not in excess of
         $5,000,000, if such release is consented to by the Requisite Lenders or
         (D) against any part of the Collateral in excess of $5,000,000, other
         than Collateral that is sold or otherwise disposed of in a transaction
         permitted hereby or consented to by the Requisite Lenders, if such
         release is consented to by all the Lenders.

Each of the Lenders and the Issuers hereby directs the Administrative Agent, and
the Administrative Agent hereby agrees, to execute and deliver or file such
termination and partial release statements and do such other things as are
necessary to release Liens to be released pursuant to this Section 10.8.

OBLIGATIONS

                  The benefit of the Loan Documents and of the provisions of
this Agreement relating to the Collateral shall extend to and be available in
respect of any Secured Obligation arising under any Hedging Contract (unless the
parties to such Hedging Contract expressly specify in writing that none of the
obligations thereunder shall be considered "Obligations" hereunder), any
agreement for cash management services entered into in connection with this
Agreement (unless the parties to such agreement expressly specify in writing
that none of the

otherwise owed to Persons other than the Administrative Agent, the Lenders and
the Issuers (collectively, "Related Obligations") solely on the condition and
understanding, as among the Administrative Agent and all Secured Parties, that
(i) the Related Obligations shall be entitled to the benefit of the Loan
Documents and the Collateral to the extent expressly set forth in this Agreement
and the other Loan Documents and to such extent the Administrative Agent shall
hold, and have the right and power to act with respect to, the Guaranty and the
Collateral on behalf of and as agent for the holders of the Related Obligations,
but the Administrative Agent is otherwise acting solely as agent for the Lenders
and the Issuers and shall have no fiduciary duty, duty of loyalty, duty of care,
duty of disclosure or other obligation whatsoever to any holder of Related
Obligations, (ii) all matters, acts and omissions relating in any manner to the
Guaranty, the Collateral, or the omission, creation, perfection, priority,
abandonment or release of any Lien, shall be governed solely by the provisions
of this Agreement and the other Loan Documents and no separate Lien, right,
power or remedy shall arise or exist in favor of any Secured Party under any
separate instrument or agreement or in respect of any Related Obligation, (iii)
each Secured Party shall be bound by all actions taken or omitted, in accordance
with the provisions of this Agreement and the other Loan Documents, by the
Administrative Agent, the Requisite Lenders and the Supermajority Lenders, each
of whom shall be entitled to act at its sole discretion and exclusively in its
own interest given its own Revolving Credit Commitments and its own interest in
the Loans, Letter of Credit Obligations and other Obligations to it arising
under this Agreement or the other Loan Documents, without any duty or liability
to any other Secured Party or as to any Related Obligation and without regard to
whether any Related Obligation remains outstanding or is deprived of the benefit
of the Collateral or becomes unsecured or is otherwise affected or put in
jeopardy thereby, (iv) no holder of Related Obligations and no other Secured
Party (except the Administrative Agent, the Lenders and the Issuers, to the
extent set forth in this Agreement) shall have any right to be notified of, or
to direct, require or be heard with respect to, any action taken or omitted in
respect of the Collateral or under this Agreement or the Loan Documents and (v)
no holder of any Related Obligation shall exercise any right of setoff, banker's
lien or similar right except as expressly provided in Section 11.6 (Right of
Set-off).

                  (a) No amendment or waiver of any provision of this Agreement
or any other Loan Document nor consent to any departure by any Loan Party

and signed by the Requisite Lenders or the Supermajority Lenders; provided,
however, that no amendment, waiver or consent shall, unless in writing and
signed by the Supermajority Lenders, increase the Borrowing Base or otherwise
increase any of the advance rates above the percentages set forth in the

Equipment, Eligible Real Property or any class of Eligible Inventory; provided,
further, that no amendment, waiver or consent shall, unless in writing and
signed by each Lender directly affected thereby, in addition to the Requisite
Lenders or the Supermajority Lenders and, in the case of any amendment, the
Borrowers, do any of the following:

                           (i)      waive any of the conditions specified in
         Section 3.1 (Conditions Precedent to the Effectiveness of this
         Agreement) or Section 3.2 (Conditions Precedent to Each Loan and Letter

         provision hereof, the waiver of which requires only the concurrence of
         the Requisite Lenders;

                           (ii)     increase the Revolving Credit Commitment of
         such Lender or subject such Lender to any additional obligations;

                           (iii)    extend the scheduled final maturity of any
         Loan due to such Lender, or waive, reduce or postpone any scheduled
         date fixed for the payment or reduction of principal on such Loan (it
         being understood that Section 2.9 (Mandatory Prepayments) does not
         provide for scheduled dates fixed for payment) or of the Revolving
         Credit Commitments;

                           (iv)     reduce the principal amount of any Loan or
         Reimbursement Obligation due to such Lender (other than by the payment

         Reimbursement Obligations outstanding to such Lender or any fee payable
         hereunder to such Lender;

                           (vi)     postpone any scheduled date fixed for
         payment of such interest or fees due to such Lender;

                           (vii)    change the aggregate Ratable Portions of
         Lenders required for any or all Lenders to take any action hereunder;

                           (viii)   except as provided in Section 10.8(b)
         (Concerning the Collateral and the Collateral Documents), release
         substantially all of the Collateral or release any Borrower or
         Guarantor from its obligations under the Guaranty except in connection
         with sale or other disposition permitted by this Agreement (or
         permitted pursuant to a waiver or consent of a transaction otherwise
         prohibited by this Agreement); or

                           (ix)     amend Section 10.8(b) (Concerning the
         Collateral and the Collateral Documents) or this Section 11.1 or the
         definition of the terms "Requisite Lenders" or "Ratable Portion";

provided, further, that (a) amendments shall not be valid unless signed by the
Borrowers, (b) any amendment, waiver or consent of any provision of this
Agreement or any other Loan Document shall be effective only in the specific
instance and for the specific purpose for which given and (c) no amendment,
waiver or consent shall, unless in writing and signed by the Administrative
Agent in addition to the Lenders required above to take such action, affect the
rights or duties of the Administrative Agent under this Agreement or the other
Loan Documents.

                  (b) The Administrative Agent may, but shall have no obligation
to, with the written concurrence of any Lender, execute amendments,
modifications, waivers or consents on behalf of such Lender. Any waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which it was given. No notice to or demand on the Company or the
Borrowers in any case shall entitle any Borrower to any other or further notice
or demand in similar or other circumstances.

                                           AMENDED AND RESTATED CREDIT AGREEMENT
                                                             SUNTRON CORPORATION

                  (c) If, in connection with any proposed amendment,
modification, waiver or termination (a "Proposed Change") requiring the consent
of all affected Lenders, the consent of Requisite Lenders is obtained but the
consent of other Lenders whose consent is required is not obtained (any such
Lender whose consent is not obtained as described in this Section 11.1 being
referred to as a "Non-Consenting Lender"), then, as long as the Lender acting as
the Administrative Agent is not a Non-Consenting Lender, at the Company's
request, the Administrative Agent or an Eligible Assignee acceptable to the
Administrative Agent shall have the right with the Administrative Agent's
consent and in the Administrative Agent's sole discretion (but shall have no
obligation) to purchase from such Non-Consenting Lender, and such Non-Consenting
Lender agrees that it shall, upon the Administrative Agent's request, sell and
assign to the Lender acting as the Administrative Agent or such Eligible
Assignee, all of the Revolving Credit Commitments, and Revolving Credit
Outstandings of such Non-Consenting Lender for an amount equal to the principal
balance of all Loans held by the Non-Consenting Lender and all accrued and
unpaid interest and fees with respect thereto through the date of sale;
provided, however, that such purchase and sale shall not be effective until (x)
the Administrative Agent shall have received from such Eligible Assignee an
agreement in form and substance satisfactory to the Administrative Agent and the
Company whereby such Eligible Assignee shall agree to be bound by the terms
hereof and (y) such Non-Consenting Lender shall have received payments of all
Loans held by it and all accrued and unpaid interest and fees with respect
thereto through the date of the sale. Each Lender agrees that, if it becomes a
Non-Consenting Lender, it shall execute and deliver to the Administrative Agent
an Assignment an Acceptance to evidence such sale and purchase and shall deliver
to the Administrative Agent any Note (if the assigning Lender's Loans are
evidenced by a Note) subject to such Assignment and Acceptance; provided,
however, that the failure of any Non-Consenting Lender to execute an Assignment
and Acceptance shall not render such sale and purchase (and the corresponding
assignment) invalid.

                  SECTION 11.2 ASSIGNMENTS AND PARTICIPATIONS

                  (a) Each Lender may sell, transfer, negotiate or assign to one
or more Eligible Assignees all or a portion of its rights and obligations
hereunder (including all of its rights and obligations with respect to the
Revolving Loans, the Swing Loans and the Letters of Credit); provided, however,
that (i) if any such assignment shall be of the assigning Lender's Revolving
Credit Outstandings and Revolving Credit Commitment, such assignment shall cover
the same percentage of such Lender's Revolving Credit Outstandings and Revolving
Credit Commitment, (ii) the aggregate amount being assigned pursuant to each
such assignment (determined as of the date of the Assignment and Acceptance with
respect to such assignment) shall in no event (if less than the Assignor's
entire interest) be less than $5,000,000 or an integral multiple of $1,000,000
in excess thereof, except, in either case, (A) with the consent of the Company
and the Administrative Agent or (B) if such assignment is being made to a Lender
or an Affiliate or Approved Fund of such Lender and (iii) if such Eligible
Assignee is not, prior to the date of such assignment, a Lender or an Affiliate
or Approved Fund of a Lender, such assignment shall be subject to the prior
consent of the Administrative Agent and the Company (which consent shall not be
unreasonably withheld or delayed); and provided, further, that, notwithstanding
any other provision of this Section 11.2, the consent of the Company shall not
be required for any assignment that occurs when any Event of Default shall have
occurred and be continuing.

                  (b) The parties to each assignment shall execute and deliver
to the Administrative Agent, for its acceptance and recording, an Assignment and
Acceptance, together with any Note (if the assigning Lender's Loans are
evidenced by a Note) subject to such

                                       99

                                           AMENDED AND RESTATED CREDIT AGREEMENT

assignment. Upon such execution, delivery, acceptance and recording and the
receipt by the Administrative Agent from the assignee of an assignment fee in
the amount of $3,500 from and after the effective date specified in such
Assignment and Acceptance, (i) the assignee thereunder shall become a party
hereto and, to the extent that rights and obligations under the Loan Documents
have been assigned to such assignee pursuant to such Assignment and Acceptance,
have the rights and obligations of a Lender and, if such Lender were an Issuer,
of such Issuer hereunder and thereunder and (ii) the assignor thereunder shall,
to the extent that rights and obligations under this Agreement have been
assigned by it pursuant to such Assignment and Acceptance, relinquish its rights
(except those that survive the payment in full of the Obligations) and be
released from its obligations under the Loan Documents, other than those
relating to events or circumstances occurring prior to such assignment (and, in
the case of an Assignment and Acceptance covering all or the remaining portion
of an assigning Lender's rights and obligations under the Loan Documents, such
Lender shall cease to be a party hereto).

                  (c) The Administrative Agent shall maintain at its address
referred to in Section 11.8 (Notices, Etc.) a copy of each Assignment and
Acceptance delivered to and accepted by it and a register for the recording of
the names and addresses of the Lenders and the Revolving Credit Commitments of
and principal amount of the Loans and Letter of Credit Obligations owing to each
Lender from time to time (the "Register"). Any assignment pursuant to this
Section 11.2 shall not be effective until such assignment is recorded in the
Register. The entries in the Register shall be conclusive and binding for all
purposes, absent manifest error, and the Loan Parties, the Administrative Agent
and the Lenders may treat each Person whose name is recorded in the Register as
a Lender for all purposes of this Agreement. The entries in the Register
applicable to any Lender shall be available for inspection by the Company, the
Administrative Agent or such Lender at any reasonable time and from time to time
upon reasonable prior notice.

                  (d) Upon its receipt of an Assignment and Acceptance executed
by an assigning Lender and an assignee, the Administrative Agent shall, if such
Assignment and Acceptance has been completed, (i) accept such Assignment and
Acceptance, (ii) record the information contained therein in the Register and
(iii) give prompt notice thereof to the Company. Within five Business Days after
its receipt of such notice, the Borrowers, at their own expense, shall, if
requested by such assignee, execute and deliver to the Administrative Agent, new
Notes to the order of such assignee in an amount equal to the Revolving Credit
Commitments assumed by it pursuant to such Assignment and Acceptance and, if the
assigning Lender has surrendered any Note for exchange in connection with the
assignment and has retained Revolving Credit Commitments hereunder, new Notes to
the order of the assigning Lender in an amount equal to the Revolving Credit
Commitments retained by it hereunder. Such new Notes shall be dated the same
date as the surrendered Notes and be in substantially the form of Exhibit B
(Form of Revolving Credit Note).

                  (e) In addition to the other assignment rights provided in
this Section 11.2, each Lender may assign, as collateral or otherwise, any of
its rights under this Agreement (including rights to payments of principal or
interest on the Loans) to (i) any Federal Reserve Bank pursuant to Regulation A
of the Federal Reserve Board without notice to or consent of the Borrowers or
the Administrative Agent and (ii) any trustee for the benefit of the holders of
such Lender's Securities; provided, however, that no such assignment shall
release the assigning Lender from any of its obligations hereunder.

                  (f) Each Lender may sell participations to one or more Persons
in or to all or a portion of its rights and obligations under the Loan Documents
(including all its rights and obligations with respect to the Revolving Loans
and Letters of Credit). The terms of such participation shall not, in any event,
require the participant's consent to any amendments, waivers or other
modifications of any provision of any Loan Documents, the consent to any
departure by any Loan Party therefrom, or to the exercising or refraining from
exercising any powers or rights such Lender may have under or in respect of the
Loan Documents (including the right to enforce the obligations of the Loan
Parties), except if any such amendment, waiver or other modification or consent
would (i) reduce the amount, or postpone any date fixed for, any amount (whether
of principal, interest or fees) payable to such participant under the Loan
Documents, to which such participant would otherwise be entitled under such
participation or (ii) result in the release of all or substantially all of the
Collateral other than in accordance with Section 10.8(b) (Concerning the
Collateral and the Collateral Documents). In the event of the sale of any
participation by any Lender, (A) such Lender's obligations under the Loan
Documents shall remain unchanged, (B) such Lender shall remain solely
responsible to the other parties for the performance of such obligations, (C)
such Lender shall remain the holder of such Obligations for all purposes of this
Agreement and (D) the Borrowers, the Administrative Agent and the other Lenders
shall continue to deal solely and directly with such Lender in connection with
such Lender's rights and obligations under this Agreement. Each participant
shall be entitled to the benefits of Section 2.14(d) (Illegality), Section 2.15
(Capital Adequacy) and Section 2.16 (Taxes) as if it were a Lender; provided,
however, that anything herein to the contrary notwithstanding, no Borrower
shall, at any time, be obligated to make under Section 2.14(d) (Illegality),
Section 2.15 (Capital Adequacy) or Section 2.16 (Taxes) to the participants in
the rights and obligations of any Lender (together with such Lender) any payment
in excess of the amount such Borrower would have been obligated to pay to such
Lender in respect of such interest had such participation not been sold.

                  (g) Any Issuer may at any time assign its rights and
obligations hereunder to any other Lender by an instrument in form and substance
satisfactory to the Company, the Administrative Agent, such Issuer and such
Lender. If any Issuer ceases to be a Lender hereunder by virtue of any
assignment made pursuant to this Section 11.2, then, as of the effective date of
such cessation, such Issuer's obligations to issue Letters of Credit pursuant to
Section 2.4 (Letters of Credit) shall terminate and such Issuer shall be an
Issuer hereunder only with respect to outstanding Letters of Credit issued prior
to such date.

                  SECTION 11.3 COSTS AND EXPENSES

                  (a) Each Borrower hereby agrees to pay, jointly and severally,
or reimburse upon demand the Administrative Agent for, all of the Administrative
Agent's reasonable internal and external audit, legal, appraisal, valuation,
filing, document duplication and reproduction and investigation expenses and for
all other reasonable out-of-pocket costs and expenses of every type and nature
(including, without limitation, the reasonable fees, expenses and disbursements
of the Administrative Agent's counsel, Weil, Gotshal & Manges LLP, local legal
counsel, auditors, accountants, appraisers, printers, insurance and
environmental advisers and other consultants and agents) incurred by the
Administrative Agent in connection with (i) the Administrative Agent's audit and
investigation of the Borrowers and their Subsidiaries in connection with the
preparation, negotiation and execution of the Loan Documents and the
Administrative Agent's periodic audits of the Borrowers and their Subsidiaries,
as the case may be, (ii) the preparation, negotiation, execution and
interpretation of this Agreement (including the satisfaction or attempted

satisfaction of any of the conditions set forth in Article III (Conditions To
Loans And Letters Of Credit) of this Agreement and the Existing Credit
Agreement), the Loan Documents and any proposal letter or commitment letter
issued in connection therewith and the making of the Loans hereunder, (iii) the
creation, perfection or protection of the Liens under the Loan Documents
(including, without limitation, any reasonable fees and expenses for local
counsel in various jurisdictions), (iv) the ongoing administration of this
Agreement and the Loans, including consultation with attorneys in connection
therewith and with respect to the Administrative Agent's rights and
responsibilities hereunder and under the other Loan Documents; (v) the
protection, collection or enforcement of any of the Obligations or the
enforcement of any of the Loan Documents, (vi) the commencement, defense or
intervention in any court proceeding relating in any way to the Obligations, any
Loan Party, any of the Borrowers' Subsidiaries, the Acquisition, the Related
Documents, this Agreement or any of the other Loan Documents, (vii) the response
to, and preparation for, any subpoena or request for document production with
which the Administrative Agent is served or deposition or other proceeding in
which the Administrative Agent is called to testify, in each case, relating in
any way to the Obligations, any Loan Party, any of the Borrowers' Subsidiaries,
the Acquisition, the Related Documents, this Agreement or any of the other Loan
Documents and (viii) any amendments, consents, waivers, assignments,
restatements, or supplements to any of the Loan Documents and the preparation,
negotiation, and execution of the same.

                  (b) Each Borrower further agrees to pay or reimburse, jointly
and severally, the Administrative Agent and the Lenders and Issuers upon demand
for all reasonable out-of-pocket costs and expenses, including, reasonable
attorneys' fees (including allocated costs of internal counsel and costs of
settlement), incurred by the Administrative Agent or such Lenders and Issuers
(i) in enforcing any Loan Document or Obligation or any security therefor or
exercising or enforcing any other right or remedy available by reason of an
Event of Default, (ii) in connection with any refinancing or restructuring of
the credit arrangements provided hereunder in the nature of a "work-out" or in
any insolvency or bankruptcy proceeding, (iii) in commencing, defending or
intervening in any litigation or in filing a petition, complaint, answer, motion
or other pleadings in any legal proceeding relating to the Obligations, any Loan
Party, any of the Borrowers' Subsidiaries and related to or arising out of the
transactions contemplated hereby or by any of the other Loan Documents or the
Related Documents and (iv) in taking any other action in or with respect to any
suit or proceeding (bankruptcy or otherwise) described in clauses (i) through
(iii) above.

                  SECTION 11.4 INDEMNITEES

                  (a) The Borrowers shall, jointly and severally, indemnify and
hold harmless the Administrative Agent, the Arranger, each Lender, each Issuer
and each of their respective Affiliates, and each of the respective officers,
directors, employees, agents, advisors, attorneys and representatives of each of
the foregoing (each an "Indemnitee") from and against any and all claims,
damages, losses, liabilities and expenses (including reasonable fees and
disbursements of counsel), joint or several, that may be incurred by or asserted
or awarded against any such Indemnitee (including in connection with or relating
to any investigation, litigation or proceeding or the preparation of any defense
in connection therewith), in each case arising out of or in connection with or
by reason of this Agreement, any other Loan Document, any Obligation, any Letter
of Credit, any Related Document, or any of the transactions contemplated hereby
or thereby or any actual or proposed used of the proceeds of the Loans or
Letters of Credit (collectively, the "Indemnified Matters"), except to the
extent such claim, damage, loss, liability

                                       102

                                                             SUNTRON CORPORATION

or expense is found, in a final non-appealable judgment by a court of competent
jurisdiction to have resulted from such Indemnitee's gross negligence or willful
misconduct. In the case of an investigation, litigation or other proceeding to
which the indemnity in this Section 11.4 applies, such indemnity shall be
effective whether or not such investigation, litigation or proceeding is brought
by any Borrower, any of its directors, security holders or creditors, an
Indemnitee or any other Person, or an Indemnitee is otherwise a party thereto
and whether or not the transactions contemplated hereby are consummated. Without
limiting the foregoing, "Indemnified Matters" shall include, without limitation,
(i) all Environmental Liabilities and Costs arising from or connected with the
past, present or future operations of any Borrower or any Subsidiary thereof
involving any property subject to a Collateral Document, or damage to real or
personal property or natural resources or harm or injury alleged to have
resulted from any Release of Contaminants on, upon or into such property or any
contiguous real estate; (ii) any costs or liabilities incurred in connection
with any Remedial Action concerning any Borrower or any Subsidiary thereof;
(iii) any costs or liabilities incurred in connection with any Environmental
Lien; (iv) any costs or liabilities incurred in connection with any other matter
under any Environmental Law, including the Comprehensive Environmental Response,
Compensation and Liability Act of 1980, 49 U.S.C. ss.ss. 9601 et seq. and
applicable state property transfer laws, whether, with respect to any of such
matters, such Indemnitee is a mortgagee pursuant to any leasehold mortgage, a
mortgagee in possession, the successor in interest to any Borrower or any
Subsidiary thereof, or the owner, lessee or operator of any property of any
Borrower or any Subsidiary thereof by virtue of foreclosure, except, with
respect to those matters referred to in clauses (i), (ii), (iii) and (iv) above,
to the extent (A) incurred following foreclosure (or transfer of title to in
lieu of foreclosure) by the Administrative Agent, any Lender or any Issuer, or
the Administrative Agent, any Lender or any Issuer having become the successor
in interest to any Borrower or any Subsidiary thereof and (B) attributable
solely to acts of the Administrative Agent, such Lender or such Issuer or any
agent on behalf of the Administrative Agent or such Lender.

                  (b) The Borrowers shall, jointly and severally, indemnify the
Administrative Agent, the Lenders and each Issuer for, and hold the
Administrative Agent, the Lenders and each Issuer harmless from and against, any
and all claims for brokerage commissions, fees and other compensation made
against the Administrative Agent, the Lenders and the Issuers for any broker,
finder or consultant with respect to any agreement, arrangement or understanding
made by or on behalf of any Loan Party or any of its Subsidiaries in connection
with the transactions contemplated by this Agreement.

                  (c) The Administrative Agent, each Lender and each Issuer
agree that in the event that any such investigation, litigation or proceeding
set forth in clause (b) above is asserted or threatened in writing or instituted
against it or any other Indemnitee, or any Remedial Action, is requested of it
or any of its officers, directors, agents and employees, for which any
Indemnitee may desire indemnity or defense hereunder, such Indemnitee shall
promptly notify the Company in writing.

                  (d) Each Borrower, at the request of any Indemnitee, shall
have the obligation to defend against such investigation, litigation or
proceeding or requested Remedial Action and such Borrower, in any event, may
participate in the defense thereof with legal counsel of such Borrower's choice.
In the event that such Indemnitee requests any Borrower to defend against such
investigation, litigation or proceeding or requested Remedial Action, such
Borrower shall promptly do so and such Indemnitee shall have the right to have
legal counsel of its choice participate in such defense. No action taken by
legal counsel chosen by such Indemnitee in

defending against any such investigation, litigation or proceeding or requested
Remedial Action, shall vitiate or in any way impair the Borrowers' obligation
and duty hereunder to indemnify and hold harmless such Indemnitee.

                  (e) Each Borrower agrees that any indemnification or other
protection provided to any Indemnitee pursuant to this Agreement (including
pursuant to this Section 11.4) or any other Loan Document shall (i) survive
payment in full of the Obligations and (ii) inure to the benefit of any Person
who was at any time an Indemnitee under this Agreement or any other Loan
Document.

                  SECTION 11.5 LIMITATION OF LIABILITY

                  (a) Each Borrower agrees that no Indemnitee shall have any
liability (whether direct or indirect, in contract, tort or otherwise) to any
Borrower or any of its security holders or creditors for or in connection with
the transactions contemplated hereby, except for direct damages (as opposed to
special, indirect, consequential or punitive damages (including, without
limitation, any loss of profits, business or anticipated savings)) determined in
a final non-appealable judgment by a court of competent jurisdiction to have
resulted from such Indemnitee's breach of contract, gross negligence or willful
misconduct.

                  (b) In no event shall any Agent Affiliate have any liability
to any Loan Party, Lender, Issuer or any other Person for damages of any kind,
including direct or indirect, special, incidental or consequential damages,
losses or expenses (whether in tort or contract or otherwise) arising out of any
Loan Party or any Agent Affiliate's transmission of Approved Electronic
Communications through the Internet or any use of the Approved Electronic

                  SECTION 11.6 RIGHT OF SET-OFF

                  Upon the occurrence and during the continuance of any Event of
Default each Lender and each Affiliate of a Lender is hereby authorized at any
time and from time to time, to the fullest extent permitted by law, to set off
and apply any and all deposits (general or special, time or demand, provisional
or final) at any time held and other indebtedness at any time owing by such
Lender or its Affiliates to or for the credit or the account of any Borrower
against any and all of the Obligations now or hereafter existing whether or not
owing by such Borrower and whether or not such Lender shall have made any demand
under this Agreement or any other Loan Document and although such Obligations
may be unmatured. Each Lender agrees promptly to notify the Company after any
such set-off and application made by such Lender or its Affiliates; provided,
however, that the failure to give such notice shall not affect the validity of
such set-off and application. The rights of each Lender under this Section 11.6
are in addition to the other rights and remedies (including other rights of
set-off) that such Lender may have.

pursuant to Section 11.3 (Costs and Expenses) or Section 11.4 (Indemnitees)

Governing Eurodollar Rate Loans), Section 2.15 (Capital Adequacy) and Section
2.16 (Taxes)) in excess of its Ratable Portion of all payments of such
Obligations obtained by all the Lenders, such Lender (a "Purchasing Lender")
shall forthwith purchase from the other Lenders (each, a "Selling Lender") such
participations in their Loans or other Obligations as shall be necessary to
cause such Purchasing Lender to share the excess payment ratably with each of
them.

                  (b) If all or any portion of any payment received by a
Purchasing Lender is thereafter recovered from such Purchasing Lender, such
purchase from each Selling Lender shall be rescinded and such Selling Lender
shall repay to the Purchasing Lender the purchase price to the extent of such
recovery together with an amount equal to such Selling Lender's ratable share
(according to the proportion of (i) the amount of such Selling Lender's required
repayment to (ii) the total amount so recovered from the Purchasing Lender) of
any interest or other amount paid or payable by the purchasing Lender in respect
of the total amount so recovered.

                  (c) Each Borrower agrees that any Purchasing Lender so
purchasing a participation from a Selling Lender pursuant to this Section 11.7
may, to the fullest extent permitted by law, exercise all its rights of payment
(including the right of set-off) with respect to such participation as fully as
if such Lender were the direct creditor of any Borrower in the amount of such
participation.

                  No failure on the part of any Lender, Issuer or the
Administrative Agent to exercise, and no delay in exercising, any right

and all certificates and documents delivered hereunder or thereunder, embodies
the entire agreement of the parties and supersedes all prior agreements and

                  SECTION 11.18 CONFIDENTIALITY

                  Each Lender and the Administrative Agent agree to keep
information obtained by it pursuant hereto and the other Loan Documents
confidential in accordance with such Lender's or the Administrative Agent's, as
the case may be, customary practices and agrees that it shall only use such
information in connection with the transactions contemplated by this Agreement
and not disclose any of such information other than (a) to such Lender's or the
Administrative Agent's, as the case may be, employees, representatives and
agents who are or are expected to be involved in the evaluation of such
information in connection with the transactions contemplated by this Agreement
and who are advised of the confidential nature of such information, (b) to the
extent such information presently is or hereafter becomes available to such
Lender or the Administrative Agent, as the case may be, on a non-confidential
basis from a source other than the Borrowers, (c) to the extent disclosure is
required by law, regulation or judicial order or requested or required by bank
regulators or auditors, in each case and to the extent such assignees,
participants, grantees or counterparties agree to be bound by, and to cause
their advisors to comply with, the provisions of this Section 11.18.
Notwithstanding any other provision in this Agreement, the Company, each
Borrower, each Lender and the Administrative Agent hereby agree that each of the
