CREDIT AGREEMENT

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”).

RECITALS

A. U.S. Bank extends to SI a 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, equipment, general intangibles, and inventory of SI, as more particularly specified in various security agreements executed by SI in favor of U.S. Bank. In addition, 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, equipment, general intangibles, and inventory of the Domestic Subsidiaries. The security interests referred to in the two preceding sentences are referred to collectively in this Agreement as the “Existing Security Agreements.”

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.

NOW, THEREFORE, for valuable consideration, the receipt and sufficiency of which hereby are acknowledged, U.S. Bank and SI agree as follows:

Upon the effective date of this Agreement, the Revolving Credit Facility shall replace and supersede the operating credit facility extended by U.S. Bank to SI pursuant to the Existing Revolving Note.

Section 2.2 Use of Funds Borrowed 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 minus $1,500,000.

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 advanced to SI pursuant to the Revolving Credit Facility (the “Revolving Credit Facility Note”). Advances to SI pursuant to the Revolving Credit Facility shall be evidenced by and repaid by SI in accordance with the Revolving Credit Facility Note and this Agreement.

Section 2.5 The Revolving Loan Fee. Contemporaneously with the execution of this Agreement, SI shall pay U.S. Bank a fee of $24,375 in consideration of U.S. Bank’s commitment to extend the Revolving Credit Facility to SI on the basis set forth in this Agreement.

Section 2.11 Manner of Borrowing. In order to request an Advance under the Revolving Credit Facility, SI shall provide U.S. Bank with a written borrowing request in a form approved by U.S. Bank in its reasonable discretion. Each borrowing request by SI shall identify in reasonable 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.

In that regard, SI hereby agrees to

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 ▇▇▇▇▇▇, ▇.▇. 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

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.

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:

TERMS AND CONDITIONS

(b)

SI shall have executed and delivered to U.S. Bank agreements in form and content satisfactory to U.S. Bank in its reasonable discretion amending the Revolving Credit Facility Note and the Term Loan Note to reflect the changes thereto effected by the terms of Article II and Article III of this Fifth Amendment;

(c)	Payment of Extension Fees. SI shall have paid U.S. Bank $18,000 for the fees owed pursuant to paragraphs 2.2 and 3.3 of this Fifth Amendment;

If all of the above-described conditions precedent have not been satisfied (or waived in writing by U.S. Bank) by March 15, 2004, this Fifth Amendment shall be of no force and effect and the parties’ rights and obligations shall continue to be governed by the Credit Agreement (without giving effect to this Fifth Amendment).

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 Eligible Inventory at the time in question, provided, however, that the aggregate amount of Advances supported by Eligible Inventory shall not exceed $3,900,000 from June 1, 2003, through June 30, 2003, $3,825,000 from July 1, 2003, through July 31, 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 been deferred as noted above.

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 for the account of SI. In addition, SI promptly shall pay U.S. Bank all other customary fees and charges assessed by U.S. Bank with respect to any letters of credit issued by U.S. Bank for the account of SI.

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 Facility are not modified or amended by this Fifth Amendment. That means, among other things, that SI shall continue to make the monthly payments of interest owed in respect of the Revolving Credit Facility.

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:

“Section 3.5. Maturity Date of the Term Loan. SI shall pay U.S. Bank the entire balance of principal, interest, and fees owed pursuant to the Term Loan on the earlier of (a) July 31, 2004, or (b) the date, if any, on which the Obligations are accelerated following an Event of Default.”

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.

3.4	Term Loan Otherwise Unchanged. Except as specified in paragraphs 3.1 through 3.3 of this Fifth Amendment, the terms and conditions of the Term Loan are not modified or amended by this Fifth Amendment.

ARTICLE IV

REAFFIRMATION OF THE EXISTING TERM LOAN

4.1	Clarification of Excess Cash Flow Payment. Section 4.3 of the Credit Agreement hereby is modified, amended, and restated as follows:

“Section 4.3 Subsequent Excess Flow Payments. In 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 fiscal year exceeds the amount of Adjusted EBITDAR that would have been required to provide a Fixed Charge Coverage Ratio of 1.15 to 1.00 for such year.”

4.2

Existing Term Loan Unchanged. SI acknowledges and agrees that this Fifth Amendment does not modify, alter, or amend the Existing Term Loan and that SI’s obligations in respect of the Existing Term Loan remain in full force and effect. That means, among other things, that SI shall continue to make all of the monthly payments required by the promissory note evidencing that loan strictly in accordance with the terms of that instrument.

ARTICLE V

COLLATERAL FOR SI’S OBLIGATIONS

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 of this Fifth Amendment.

5.2

Other Documents. SI hereby agrees that until SI satisfies the Obligations in full and U.S. Bank has no further commitment to extend credit to SI, SI promptly shall execute 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).

5.3

Anticipated Collateral Examination. SI acknowledges that U.S. Bank has informed SI that U.S. Bank intends to conduct an examination of the Collateral promptly after the parties enter into this Fifth Amendment. SI hereby agrees to provide U.S. Bank access to the Collateral, and to SI’s and the Domestic Subsidiaries’ books and records regarding the Collateral. SI acknowledges that it shall be responsible for the costs of the above-described examination of the Collateral and shall reimburse U.S. Bank for such costs (or pay such costs in the first instance) in accordance with Section 7.1 of the Credit Agreement.

““Pro-Rated Maintenance Capital Expenditures” means that portion of an agreed-upon level of annual Capital Expenditures of $275,000 allocable to the measurement period in question on a pro-rated basis. For example, if the measurement period in question is a nine-month period, the Pro-Rated Maintenance Capital Expenditures would be $206,250 (i.e., nine-twelfths of $275,000).”

6.3	Revised Definition. The definition of the term Fixed Charges set forth in Section 1.1 of the Credit Agreement hereby is modified, amended, and restated as follows:

““Fixed Charges” means, for any period in question, the sum of (a) interest expense of SI, (b) the aggregate amount of all regularly scheduled principal payments (other than principal payments with respect to the Revolving Credit Facility) in respect of any Funded Indebtedness (provided, however, that for purposes of calculating the financial covenants in this Agreement, the monthly principal payments with respect to the Term Loan shall be deemed to be $25,000 per month), (c) prepayments of any Funded Indebtedness (other than the Obligations), and (d) lease and rent expense of SI.”

“(i) Audited Financial Statement and Covenant Certification. Within 120 days of the end of SI’s fiscal year, a copy of an audited consolidated financial statement in respect of SI prepared by a certified public accounting firm acceptable to U.S. Bank in its reasonable discretion

and a certification by such accounting firm that SI was in compliance with the financial covenants contained in Sections 10.1 through 10.3 of the Credit Agreement as of the end of SI’s fiscal year in question (or identifying any of such covenants that SI was not in compliance with as of the end of the year in question);”

6.5	Revised Financial Covenants. Sections 10.1 through 10.4 of the Credit Agreement hereby are modified, amended, and restated as follows:

Notwithstanding anything in the Credit Agreement to the contrary, Net Income to be utilized in calculating EBITDA or EBITDAR shall be determined without deductions for current period increases in inventory reserves.

6.6

Possible New Financial Covenants. If U.S. Bank’s commitment to provide the Revolving Credit Facility to SI is extended beyond July 31, 2004, on the basis set forth in the second sentence of Section 2.10 of the Credit Agreement, U.S. Bank and SI shall negotiate in good faith to establish financial covenants (based upon SI’s fiscal 2005 Budget) for the fiscal period ending October 31, 2004. If the parties are unable to agree upon those covenants, U.S. Bank shall determine the covenants and that determination shall be binding on SI.

6.7

Authorization. SI hereby represents and warrants that the execution, delivery, and performance by SI and the Domestic Subsidiaries of this Fifth Amendment have been duly authorized by all necessary corporate action of SI and the Domestic Subsidiaries, do not require any further shareholder approval, or the approval or consent of any trustee or the holders of any Indebtedness of SI or the Domestic Subsidiaries, do not contravene any law, regulation, rule, or order binding on SI or the Domestic Subsidiaries, or any of the organizational documents, and do not contravene the provisions of or constitute a default under any indenture, mortgage, contract, or other agreement or instrument to which SI (or a Domestic Subsidiary) is a party, or by which SI (or a Domestic Subsidiary) or any of its properties may be bound or affected, except as has been disclosed to U.S. Bank in writing. Contemporaneously with the execution of this Fifth Amendment, SI shall deliver to U.S. Bank corporate resolutions authorizing SI to obtain the Loans and to enter into this Fifth Amendment and the Loan Documents and identifying the officer or officers of SI and the Domestic Subsidiaries authorized to execute this Fifth Amendment and other Loan Documents to be executed on or after the date of this Fifth Amendment.

Additional Event of Default. In addition to the matters specified in Section 12.1 of the Credit Agreement, the breach by SI of any agreement with any third party that would be likely to have a Material Adverse Effect (as determined by U.S. Bank in its reasonable discretion) shall constitute a default under Section 12.1 of the Credit Agreement.

6.9

Permitted Assets Sales. SI has informed U.S. Bank that SI intends to sell excess equipment and excess inventory of SI. U.S. Bank hereby agrees to such sales, provided that all net proceeds of the sale of any excess inventory or excess equipment of SI are deposited promptly into the Cash Collateral Account for application to the Revolving Credit Facility. On or before the time that SI is required to deliver its monthly financial statements to U.S. Bank in accordance with the provisions of Section 9.9(f) of the Credit Agreement, SI shall deliver to U.S. Bank a written report identifying in reasonable detail the types and amounts of excess equipment and excess inventory sold by SI during the immediately preceding calendar month and the gross proceeds and net proceeds received by SI in connection with such sales.

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:

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 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

6.11

Expenses of U.S. Bank. SI shall reimburse U.S. Bank for all reasonable costs and expenses incurred by U.S. Bank in connection with U.S. Bank’s banking and lending 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.
