This Credit Agreement (the Agreement) is entered into on June , 2002, between U.S. BANK NATIONAL ASSOCIATION (U.S.
Bank) and SI TECHNOLOGIES, INC. (SI).

revolving credit facility in the amount of $8,000,000 and a term loan facility. The terms and conditions of those credit facilities are set forth in an Amended and Restated Credit Agreement dated July 10, 1998, between U.S. Bank and SI (which
agreement, as modified and amended, is referred to herein as the Existing Credit Agreement).



B. As of June 12, 2002, SI owed U.S. Bank the principal amount of $7,010,024.51 and accrued interest of $144,359.66 pursuant to a promissory note dated March 9, 2001, evidencing SIs obligations in respect of the
existing revolving credit facility extended by U.S. Bank. The promissory note referred to in the preceding sentence is referred to below as the Existing Revolving Note.



C. As of June 12, 2002, SI owed U.S. Bank the principal amount of $4,708,898.71 and accrued interest of $7,913.57 pursuant to a promissory
note dated November 15, 2000, in the original principal amount of $6,891,071.32 (the Existing Term Loan Note). The loan evidenced by the Existing Term Loan Note is referred to in this Agreement as the Existing Term Loan.



D. Interest continues to accrue on SIs obligations to U.S. Bank pursuant
to the Existing Revolving Note and the Existing Term Loan Note on and after June , 2002. In addition, SI is obligated to reimburse U.S. Bank (or pay directly if requested to do so by U.S. Bank) for fees and costs
incurred by U.S. Bank in connection with its banking relationship with SI, including reasonable attorney fees.



E. SIs obligations pursuant to the Existing Revolving Note and the Existing Term Loan Note are secured by first priority security interests and liens in, among other things, all accounts, chattel paper,

Loan Note are secured by first priority security interests and liens in, among other things, all accounts, chattel paper, equipment, general intangibles, and inventory of the Domestic Subsidiaries. The security interests referred to in the two

F. SIs obligations pursuant to the Existing Revolving Note and the Existing Term Loan Note also are secured by a pledge of the stock owned by SI of Allegany, Inc.,
NV Technology, Inc., and Revere. Furthermore, the existing loans are secured by Allegany, Inc.s, pledge of the stock it owns of Allegany Technologies, Inc., and by Selectaid Limiteds pledge of stock it owns of Revere BV. The pledge
agreements referred to in this Recital F are referred to below collectively as the Existing Pledge Agreements.



G. The credit facility evidenced by the Existing Revolving Note has matured and U.S. Banks commitment to extend revolving credit to SI has expired. SI has asked
U.S. Bank to continue to extend a revolving credit facility to SI. U.S. Bank is willing to do so, subject to the terms and conditions set forth in this Agreement.

Under the Revolving Credit Facility. Upon the effective date of this Agreement, SI shall cause an Advance to be made under the Revolving Credit Facility in an amount equal to the principal balance outstanding under the Existing Revolving Note

credit facility governed by this Agreement (which credit facility is referred to in this Agreement as the Revolving Credit Facility) shall be used by SI only for general corporate purposes in the ordinary course of SIs business.



Section 2.3 Maximum Revolving Credit Commitment. The
maximum amount of credit that may be outstanding to SI under the Revolving Credit Facility at any time is the lesser of (a) $6,500,000, or (b) the Borrowing Base at the time in question. If the amount outstanding with respect to the Revolving Credit
Facility at any time exceeds the lesser of the amounts specified in the preceding sentence, SI within three Business Days shall pay U.S. Bank an amount equal to such excess (and SIs failure to make such payment shall constitute an Event of
Default).



Section 2.4 The Revolving Credit Facility
Note. Contemporaneously with the execution of this Agreement, SI shall execute and deliver to U.S. Bank a promissory note in form and content satisfactory to U.S. Bank in its reasonable discretion evidencing SIs obligation to repay amounts

detail the amount of the Borrowing Base (as determined in the bi-weekly borrowing base certificate then in effect) and the amount of the Advance requested by SI. Each borrowing request by SI shall constitute a representation and warranty by SI that,
as of the date of the request, no Event of Default (or no event that with the giving of notice, or the passage of time, or both, would constitute an Event of Default) has occurred and is continuing. U.S. Bank will disburse any Advance to which SI is
entitled under this Agreement by crediting the proceeds of the Advance to operating checking account no. 153501647538 maintained by SI with U.S. Bank. U.S. Bank shall not be required to make any Advance requested by SI at any time that SI has not

MISCELLANEOUS PROVISIONS



Section 7.1 Expenses of U.S. Bank. SI shall reimburse U.S. Bank for

amounts, or on the Existing Term Loan Maturity Date, whichever occurs first.



Section 7.2 Prohibition on Overdrafts and Unfunded Items. SI hereby agrees that it shall maintain sufficient funds in its accounts with U.S. Bank to cover all items drawn on such accounts (i.e., SI shall not
overdraw any account with U.S. Bank). All items presented to U.S. Bank for payment for which there are insufficient funds in the account on which the item is drawn may be dishonored by U.S. Bank in its reasonable discretion without any prior notice
to SI. U.S. Bank shall have no obligation to notify SI in advance (i.e., before the item or items in question is or are returned unpaid) that items have been presented on any of SIs accounts that will result in an overdraft if funds are not
deposited into the account in question.



Section 7.3 Cash

discharges U.S. Bank and U.S. Banks agents, principals, successors, assigns, employees, officers, directors, and attorneys, and each of them, of and from any and all claims, demands, damages, suits, rights, defenses, offsets, or causes of
action of every kind and nature that SI has or may have as of the date it executes this Agreement, whether known or unknown, contingent or matured, foreseen or unforeseen, asserted or unasserted, including, but not limited to, all claims for
compensatory, general, special, consequential, incidental, and punitive damages, attorney fees, and equitable relief. In that regard, SI hereby agrees to



74



---

waive and relinquish, and by executing this Agreement shall be deemed to have waived and relinquished to the fullest extent permitted by law, the provisions,
rights, and benefits of Section 1542 of the California Civil Code, which provides that:



A general release does not extend to claims which the creditor does not know or suspect to exist in his favor at the time of executing the release, which if known by him must have materially affected his
settlement with the debtor.



Furthermore, SI hereby waives any and all
provisions, rights, and benefits conferred by any laws of any state or territory of the United States, or principles of common law, that are similar, comparable, or equivalent to Section 1542 of the California Civil Code. SI recognizes that SI may
discover after the effective date of this Agreement facts in addition to or different from those that SI knows or believes to be true with respect to the subject matter of the released claims but hereby stipulates and agrees that as of the effective
date of this Agreement SI fully, finally, and forever settles and releases any and all released claims, known or unknown, as described above.



Section 7.5 Foreign Credit Insurance. SI acknowledges that U.S. Bank is not prepared to extend credit to SI secured by Eligible Accounts, other
than Eligible Domestic Accounts, unless such accounts are insured under the Credit Insurance Policy and SI takes all steps required by that policy to recover payment from the insurer with respect to Eligible Insured Foreign Accounts that are not
paid by the account debtor. SI hereby represents and warrants that it shall use its best reasonable efforts to obtain the Credit Insurance Policy as soon as reasonably practicable after the execution of this Agreement.



Section 7.6 Information Regarding Credit Insurance Policy. SI hereby
agrees that, upon obtaining the Credit Insurance Policy, SI promptly shall provide U.S. Bank with a copy of the Credit Insurance Policy, all endorsements, riders, schedules, and exhibits to that policy, all modifications or amendments of the Credit
Insurance Policy, and all notices received by SI from the insurer under the Credit Insurance Policy. In addition, SI immediately shall notify U.S. Bank in writing of the receipt by SI of any communication from the insurer under the Credit Insurance
Policy informing SI of the insurers intention to terminate or cancel the Credit Insurance Policy. SI shall obtain the agreement (in writing) of the insurer under the Credit Insurance Policy to give U.S. Bank at least 45 days prior
written notice of the insurers intended termination, cancellation, or material modification of the Credit Insurance Policy (provided, however, that if the reason for such termination or cancellation is nonpayment of the policy premium, ten
Business Days written notice to U.S. Bank shall be satisfactory). SI hereby acknowledges and agrees that if SI fails to timely pay the policy premium with respect to the Credit Insurance Policy, U.S. Bank may (but shall not be required to) pay
such premium and the amount paid by U.S. Bank shall become part of the Obligations.



Section 7.7 Claim Procedure. SI recognizes that U.S. Bank expects SI to strictly and timely comply with all provisions of the Credit Insurance Policy related to filing claims under the policy, providing proof
of loss under the policy, and notifying account debtors of their defaults as required by the Credit Insurance Policy and SI hereby agrees to timely comply with all such provisions of the Credit Insurance Policy. SI hereby irrevocably appoints U.S.
Bank as SIs true and lawful attorney (such appointment being coupled with an interest), with full power of substitution, in the name of SI, to take any and all steps or actions required by the Credit Insurance Policy to timely and
appropriately assert a claim under that policy, subject to the conditions specified in this Agreement. SI hereby agrees that if SI has not submitted a claim with respect to a past-due Eligible Insured Foreign Account within 60 days of the deadline
for submitting a claim under the Credit Insurance Policy for full payment of the Account in question, SI shall deliver to U.S. Bank a completed claim form with respect to the Account in question (which claim form shall be in form and content
satisfactory to the insurer under the Credit Insurance Policy and shall be accompanied by any and all materials required by the insurer to establish proof of loss). At the same time, SI shall notify U.S. Bank in writing whether SI intends to make a
claim under the Credit Insurance Policy with respect to the Account in question. If SI informs U.S. Bank that SI does not intend to make a claim under the Credit Insurance Policy with respect to an Account, the Account in question shall cease to be
an Eligible Insured Foreign Account and SI within three Business Days shall pay U.S. Bank the amount by which SIs obligation exceeds the Borrowing Base (and SIs failure to make such payment shall constitute an Event of Default).
Furthermore, if SI fails to timely provide the notice and the claim form specified above, or if SI has not taken any action that U.S. Bank reasonably believes is a condition precedent under the Credit Insurance Policy to receive payment in full
under that policy of a claim with respect to an Account included in the Borrowing Base, and if SI fails to provide the notice and claim form (or take action with respect to a claim under the Credit Insurance Policy, as applicable) within three
Business Days of U.S. Bank giving SI written notice of such failure or inaction, then the Account in question shall cease to be an Eligible Insured Foreign Account and SI shall have three Business Days to pay U.S. Bank an amount equal to the amount
by which the indebtedness under the Revolving Credit Facility exceeds the



75



---

Borrowing Base following the removal of that Account from that borrowing base (and SIs failure to make such payment shall constitute an Event of
Default). If SI fails to make the payment required by either of the two preceding sentences following the removal of an Account from the Borrowing Base, U.S. Bank may use the power of attorney granted in this Section 7.7 to take any and all steps or
actions U.S. Bank reasonably believes are necessary to cause a claim to be made under the Credit Insurance Policy for payment in full of the Account in question (which actions that may be taken by U.S. Bank include, but are not limited to, providing
notice of default to the account debtor, providing proof of loss to the insurer under the Credit Insurance Policy, or asserting a claim for payment under the policy with respect to the Account in question). Notwithstanding the power of attorney
granted herein, U.S. Bank shall have no obligation to take any action on behalf of SI under or with respect to the Credit Insurance Policy.

proceedings, investigations, or claims against or affecting SI or any Subsidiary now pending before any court, arbitrator, or Governmental Authority that if determined adversely to SI or the Subsidiary would be likely to have a Material Adverse

Section 8.11 Other Agreements. Neither SI nor any Subsidiary is in
material breach of or default under any agreement to which SI (or a Subsidiary) is a party, or that is binding on SI (or a Subsidiary) or any of its assets, whereby such breach would have a Material Adverse Effect.



Section 8.12 Federal Reserve Regulations. Neither SI nor any
Subsidiary is engaged principally or as one of its important activities in the business of extending credit for the purpose of purchasing or carrying any margin stock (within the meaning of Federal Reserve Regulation U), and no part of the proceeds
of any loan from U.S. Bank to SI will be used to purchase or carry any such margin stock or to extend credit to others for the purpose of purchasing or carrying any such margin stock, or for any other purpose that violates the applicable provisions
of any Federal Reserve Regulation. If requested to do so by U.S. Bank, SI will furnish to U.S. Bank a statement conforming with the requirements of Regulation U.



Section 8.13 Compliance With Laws. SI and the Subsidiaries are in compliance in all material respects with all laws,
regulations, rules, and orders of Governmental Authorities applicable to SI and the Subsidiaries, or to their operations or property (including, but not limited to, laws governing the use or disposition of Hazardous Materials and the Employee
Retirement Income Security Act of 1974 (as amended)), except any thereof whose validity is being contested in good faith by appropriate proceedings upon stay of execution of the enforcement thereof.



Section 8.14 Continuing Representations. SI hereby acknowledges and
agrees that the representations of SI in this Article VIII of this Agreement are continuing representations and that each request for an Advance by SI under this Agreement constitutes a reaffirmation by SI that such representations are accurate as

FIFTH
AMENDMENT OF CREDIT AGREEMENT



This Fifth Amendment of Credit Agreement (the
Fifth Amendment) is entered into as of March 1, 2004, between U.S. BANK NATIONAL ASSOCIATION (U.S. Bank) and SI TECHNOLOGIES, INC. (SI).



RECITALS



A. SI and U.S. Bank are parties to a Credit Agreement dated as of June 26, 2002. That agreement, as amended, is referred to in this Fifth Amendment as the Credit
Agreement. Capitalized terms used in this Fifth Amendment that are not defined herein have the meanings assigned to such terms in the Credit Agreement.



B. The Revolving Credit Facility and the Term Loan extended by U.S. Bank to SI pursuant to the Credit Agreement matured on January 2, 2004. Furthermore, SI is in default
under the Credit Agreement as a result of SIs failure to comply with certain of the financial covenants contained in Article X of the Credit Agreement for measurement periods prior to the date of this Fifth Amendment and SIs failure to
comply with the limitation on Capital Expenditures contained in Section 11.7 of the Credit Agreement during its fiscal year 2003 (which Events of Default are referred to in this Fifth Amendment collectively as the Existing Defaults).



C. SI has asked U.S. Bank to extend the maturity date of the Revolving Credit
Facility and the Term Loan and to waive the Existing Defaults. U.S. Bank is willing to do so, subject to the terms and conditions set forth in this Fifth Amendment.



NOW, THEREFORE, for valuable consideration, the receipt and sufficiency of which hereby are acknowledged, the parties to this Fifth
Amendment agree as follows:

ARTICLE II



MODIFICATION OF THE REVOLVING CREDIT FACILITY



|2.1 | Reduction of U.S. Banks Revolving Credit Commitment. Section 2.2 of the Credit Agreement hereby is modified, amended, and restated as follows:
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------



Section 2.3 Maximum Revolving Credit
Commitment. The maximum amount of credit available to SI under the Revolving Credit Facility at any time (including letters of credit issued by U.S. Bank for the account of SI) is the lesser of (a) (i) $6,500,000 through February 29, 2004, and
(ii) $6,000,000 thereafter, or (b) the Borrowing Base at the time in question. If the amount outstanding with respect to the Revolving Credit Facility (including letters of credit issued by U.S. Bank for the account of SI) at any time exceeds the
lesser of the amounts specified in the preceding sentence, SI within three Business Days shall pay U.S. Bank an amount equal to such excess (and SIs failure to make such payment shall constitute an Event of Default).



|2.2 | Modification of the Borrowing Base. Section 2.8 of the Credit Agreement hereby is modified, amended, and restated as follows:
|--- | -----------------------------------------------------------------------------------------------------------------------------



Section 2.8 The Borrowing Base. As used in this
Agreement, the term Borrowing Base means the sum of (a) 80 percent of Eligible Domestic Accounts Receivable at the time in question, (b) 90 percent of Eligible Foreign Accounts Receivable at the time in question, and (c) 50 percent of

2003, $3,750,000 from August 1, 2003, through March 31, 2004, and $3,625,000 on April 1, 2004, and thereafter



|2.3 | Extension of U.S. Banks Commitment to Provide the Revolving Credit Facility. Section 2.10 of the Credit Agreement hereby is modified, amended, and restated as follows:
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------



On the earlier of (a)
July 31, 2004 (which date shall be extended to January 2, 2005, if SI has satisfied the conditions specified in the following sentence), or (b) acceleration of the Obligations following an Event of Default, if any, under this Agreement, U.S.
Banks commitment to extend credit pursuant to the Revolving Credit Facility shall terminate. If SI repays the Term Loan in full by July 31, 2004, and no Default or Event of Default exists on July 31, 2004, U.S. Banks commitment to
provide credit to SI pursuant to the Revolving Credit Facility shall be extended to January 2, 2005. The date on which U.S. Banks commitment to extend credit to SI terminates, as specified in the first sentence of this Section 2.10 of this
Agreement, is referred to in this Agreement as the Maturity Date. On the Maturity Date, SI shall be obligated to pay in full the entire balance of principal, interest, and fees owed pursuant to the Revolving Credit Facility Note.



|2.4 | Revolving Credit Facility Extension Fee. Prior to or contemporaneously with the execution of this Fifth Amendment, SI shall pay U.S. Bank $15,000 in consideration of U.S.
Banks agreement to extend its commitment in respect of the Revolving Credit Facility on the basis set forth in this Fifth Amendment. In addition, on or before the earlier of (a) July 31, 2004, or (b) acceleration of the Obligations following
an Event of Default, SI shall pay U.S. Bank an additional $15,000. The fee described in the preceding sentence shall be fully earned by U.S. Bank on the date this Fifth Amendment becomes effective, although the obligation of SI to pay that fee has

|2.5 | Letter of Credit Subfacility. Pursuant to the terms of the Credit Agreement (as amended hereby) and various other agreements (including a reimbursement agreement) executed by
SI in favor of U.S. Bank, U.S. Bank shall issue letters of credit for the account of SI. The aggregate amount of letters of credit issued by U.S. Bank for the account of SI and outstanding at any time shall not exceed $100,000. The face amount of
each letter of credit issued by U.S. Bank for the account of SI and outstanding at any time in question shall constitute an Advance under the Revolving Credit Facility at such time.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2.6 | Letter of Credit Fees and Charges. SI shall pay U.S. Bank an annual issuance fee of 1.25 percent per annum in respect of each outstanding letter of credit issued by U.S. Bank

|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2.7 | Revolving Credit Facility Otherwise Unchanged. Except as specified in paragraphs 2.1 through 2.6 of this Fifth Amendment, the terms and conditions of the Revolving Credit

|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



ARTICLE III



MODIFICATION OF THE TERM LOAN



|3.1 | Revised Payment Schedule. Section 3.4 of the Credit Agreement hereby is modified, amended, and restated as follows:
|--- | -------------------------------------------------------------------------------------------------------------------



Section 3.4 Repayment Terms of the Term Loan.
SI shall make monthly payments of interest in arrears to U.S. Bank in respect of the Term Loan commencing on July 1, 2002, and on the first day of each month thereafter. In addition, on the date of this Agreement, and on July 25, 2002, and the
twenty-fifth day of each month thereafter through and including February 25, 2004, SI shall make principal payments to U.S. Bank in respect of the Term Loan in the amount of $25,000. Furthermore, on or about March 1, 2004, and the first day of each
month thereafter through and including July 1, 2004, SI shall make principal payments to U.S. Bank in respect of the Term Loan in the amount of $175,000.



SI shall make its March 2004 principal payment in respect of the Term Loan in the amount of $175,000 at the time SI executes and delivers this Fifth Amendment to U.S.
Bank. SI hereby authorizes U.S. Bank to cause Advances to be made under the Revolving Credit Facility to make SIs March 2004 principal payment and subsequent principal payments in respect of the Term Loan. If sufficient credit is not available
to SI under the Revolving Credit Facility to make any such principal payment in respect of the Term Loan when due, and SI does not otherwise timely make such payment in a manner permitted by the terms of the Credit Agreement, an Event of Default
shall occur and exist.



|3.2 | Extension of the Maturity Date of the Term Loan. Section 3.5 of the Credit Agreement hereby is modified, amended, and restated as follows:

|3.3 | Term Loan Extension Fee. Prior to or contemporaneously with the execution of this Fifth Amendment, SI shall pay U.S. Bank $3,000 in consideration of U.S. Banks
agreement to extend the maturity date of the Term Loan on the basis set forth herein.

addition to the other payments SI is required to make under this Agreement and under the Notes to U.S. Bank, on or before September 15, 2003, and the same day of each year thereafter through and including 2005, SI shall pay U.S. Bank (for
application to the Existing Term Loan) an amount equal to SIs Excess Cash Flow (if any). As used in this Agreement, the term Excess Cash Flow means the amount by which actual Adjusted EBITDAR for SIs immediately preceding

of that instrument.

|5.1 | Continued Validity of the Security Documents. SI hereby expressly reaffirms and acknowledges the validity of the Security Documents, the accuracy of the information contained
in those documents, and SIs grant of security interests and liens in favor of U.S. Bank in the Collateral. SI acknowledges and agrees that the Security Documents, and the security interests and liens created by those agreements in the
Collateral, secure payment of the Obligations. Furthermore, SI acknowledges and agrees that the Security Documents, and the security interests and liens created thereby in the Collateral, shall continue in full force and effect after the execution

and deliver to U.S. Bank all documents reasonably deemed necessary or desirable by U.S. Bank to create, evidence, perfect, or continue U.S. Banks security interests or liens in the Collateral. Furthermore, until SI satisfies the Obligations in
full and U.S. Bank has no further commitment to extend credit to SI, SI authorizes U.S. Bank to take such actions as U.S. Bank reasonably deems necessary or desirable to create, evidence, perfect, or continue U.S. Banks security interests or
liens in the Collateral (including, but not limited to, filing financing statements).

|6.10 | Release of Claims. SI hereby releases and forever discharges U.S. Bank and U.S. Banks agents, principals, successors, assigns, employees, officers, directors, and
attorneys, and each of them, of and from any and all claims, demands, damages, suits, rights, defenses, offsets, or causes of action of every kind and nature that SI has or may have as of the date it executes this Fifth Amendment, whether known or
unknown, contingent or matured, foreseen or unforeseen, asserted or unasserted, including, but not limited to, all claims for compensatory, general, special, consequential, incidental, and punitive damages, attorney fees, and equitable relief. In
that regard, SI hereby agrees to waive and relinquish, and by executing this Fifth Amendment shall be deemed to have waived and relinquished to the fullest extent permitted by law, the provisions, rights, and benefits of Section 1542 of the
California Civil Code, which provides that:
|---- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

debtor.

and benefits conferred by any laws of any state or territory of the United States, or principles of common law, that are similar, comparable, or equivalent to Section 1542 of the California Civil Code. SI recognizes that SI may discover after the
effective date of this Fifth Amendment facts in addition to or different from those that SI knows or believes to be true with respect to the subject matter of the released claims but hereby stipulates and agrees that as of the effective date of this
Fifth Amendment SI fully, finally, and forever settles and releases any and all released claims, known or unknown, as described above

relationships with SI, including, but not limited to, recording charges, escrow charges, appraisal costs, environmental survey and investigation costs, collateral examination and inspection costs, and the reasonable fees and expenses of legal
counsel for U.S. Bank (including fees and expenses incurred in connection with the preparation, negotiation, closing, administration, amendment, modification, and enforcement of this Fifth Amendment, or the agreement evidenced hereby); the
preservation, protection, or disposition of the Collateral (or U.S. Banks security interests therein); or as required by applicable law, rules, policies, and regulations. The amounts owed by SI pursuant to the preceding sentence of this Sixth
Amendment shall be paid by SI in the ordinary course of SIs business after U.S. Bank bills SI for such amounts, or on the Maturity Date, whichever occurs first.
