The matters outlined herein constitute a proposal as to certain of the terms and conditions under which the Bank may provide working capital financing. It is intended to be used as a vehicle to confirm certain understandings, encourage continued discussions and further the due diligence, and does not constitute a commitment on the part of the Bank at this time. Borrower: Microsemi Corporation & Subsidiaries Facility Type and Amount: $15,000,000 revolving line of credit. Within the line of credit, Borrower may utilize eligible Bankers Acceptances to an aggregate of $5,000,000 with each Bankers Acceptance in an amount not less than $500,000. The tenor of each Bankers Acceptance will be, at the option of Borrower, from 30 to 90 days. Purpose: A line of credit under which Bank will make advances to Borrower from time to time up to and including the maturity date as referenced below, the proceeds of which shall be used for general operating needs. Initial funding will retire revolving debt and term loan balance under current line of credit with Coast Business Credit and participant. Interest Rate and Fees: Advances: Zero percent (0.00%) in excess of Imperial Bank's announced Prime Rate as it may vary from time to time. Interest will be payable monthly, and is calculated on a 360 day basis. Bankers Acceptances: Two percent (2.00%) in excess of Imperial Bank's announced Bankers Acceptance Rate for the term selected by Borrower. Interest charged will be calculated at a discount from the face amount of the Bankers Acceptance created by Bank on the behalf of Borrower, based on a 360-day year. A one-quarter percent (0.25%) loan fee, or $37,500, payable at loan closing. A one-eighth percent (0.125%) unused commitment fee, computed and payable quarterly based on the difference between the facility amount and the average outstanding principal balance for the period then-ended. However, if the average outstanding borrowings exceed $8,000,000 for any such period, there shall be no unused commitment fee for such period. Repayment Schedule: Interest only; due monthly on the first day of each month. Principal due at maturity. Maturity: 364 days. Collateral: Borrower shall execute a Security Agreement and UCC-1 Financing Statement providing Bank with a first priority security interest in all corporate assets including, but not limited to, accounts receivable, inventory, equipment and general intangibles. Principal Loan Covenants: All extension of credit proposed by the Bank to Borrower, as set forth herein will be subject to and governed by a Security and Loan agreement and a Credit Terms and Conditions Agreement acceptable to Bank. These terms and conditions may include, but not be limited to, the following: 1) Submit quarterly 10-Q financial reports within forty-five (45) days following end of each quarter. 2) Submit annual audited financial statements (together with Form 10-K) audited by an independent accounting firm acceptable to Bank, within ninety (90) days of each fiscal year end. 3) Submit 12-month financial projections quarterly within forty-five (45) days following end of each quarter. 4) Borrower will be required to maintain profitable operations on a quarterly basis. 5) Borrower will be required to maintain yet to be determined minimum levels for working capital, current ratio, quick ratio, and tangible net worth, and a maximum leverage ratio. Borrower will be required to comply with other covenants that Bank may deem appropriate. 6) All other information that Bank may reasonably request. Conditions Precedent to Lending: 1) Satisfactory completion of Bank's due diligence process. 2) No material adverse change in Borrower's financial condition prior to funding. 3) Formal credit approval by Imperial Bank and issuance of a formal commitment. 4) Evidence satisfactory to Imperial Bank of the perfections of all security interests to be granted by Borrower to Bank. 5) Completion of documentation and final terms of the proposed financing satisfactory to Bank. Confidentially: This letter is provided solely for your information and is delivered to you with the understanding that neither it, nor its substance, shall be disclosed to any third person, except those who are in confidential relationship with you, or where the same is required by law. This letter is meant to be a working document, outlining the general terms and conditions under which Imperial Bank would be willing to consider a financing arrangement for Microsemi Corporation and Subsidiaries. It is not meant to be a comprehensive list of terms and conditions that may apply to any future commitment or any credit agreement or other document that may be entered into by and between Bank and Borrower. Rather, it is intended to only outline certain basic points of business understanding around which further discussions may take place. Please understand that by approval of this proposal you acknowledge that it is issued at a time when the Bank has not undertaken a full business, credit and legal analysis of the Borrower. As a result of further analysis and investigation by us, or by reason of information of which we are not now aware, impediments to closing may be discovered. We may require that the arrangements be restructured or otherwise modified to make allowance for such impediments, or they may be so serious as to prevent the closing of these financial arrangements. We hope this proposal is acceptable to you, and request that you execute the enclosed copy of this letter and return it to us prior to June 21, 1996, at which time this proposal will expire. We look forward to your decision soon and to the possibility of establishing a long and mutually beneficial relationship with you and your fine company. Sincerely, IMPERIAL BANK /s/ Alan D.
