These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, such financial statements present fairly, in all material respects, the financial position of the Company as of June 30, 1997 and 1998, and the results of its operations and its cash flows for each of the three years in the period ended June 30, 1998 in conformity with generally accepted accounting principles.

(A Controlled Subsidiary of SymmetriCom, Inc.) NOTES TO FINANCIAL STATEMENTS Years Ended June 30, 1996, 1997 and 1998 1. Organization and Significant Accounting Policies Organization - Linfinity Microelectronics Inc. ("Linfinity" or the "Company") (a controlled subsidiary of SymmetriCom, Inc.) designs, manufactures, and markets linear and mixed signal integrated circuits as well as systems-engineered modules primarily for use in power management and communication applications in the commercial, industrial, and defense and space markets. The Company was founded in 1968 as Silicon General Semiconductors ("SGS"). In July 1993, SGS became a controlled subsidiary of SymmetriCom, Inc. (the "Parent") and changed its name to Linfinity Microelectronics Inc. Fiscal Period - The Company, for presentation purposes, presents each fiscal year as if it ended on June 30. However, the Company's fiscal year ends on the Sunday closest to June 30. All references to years refer to the Company's fiscal years. Fiscal years 1996, 1997 and 1998 consist of 52 weeks. Estimates and Certain Significant Risks and Uncertainties - The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The Company operates in a rapidly changing environment that involves a number of risks, some of which are beyond the Company's control, that could have a material adverse effect on the Company's business, operating results, and financial condition. These risks include variability and uncertainty of revenues and operating results; product concentration, technological change, and new products; competition; intellectual property/litigation; management of growth; dependence on key personnel; limited sources of component supply; licenses from third parties; geographic concentration; acquisitions and investments; international operations; regulatory requirements; expansion of distribution channels; and year 2000 compatibility issues. Concentration of Credit Risk - The Company's cash and cash equivalents are deposited with a major financial institution. At times such deposits may be in excess of insured limits. Management believes that the Company's investments in cash equivalents have minimal credit risk. The Company sells products primarily to companies in North America and Asia-Pacific. The Company maintains reserves for estimated potential credit losses. Cash and Cash Equivalents - Cash equivalents are short-term, highly liquid cash investments with an original maturity of less than 90 days. 9 Short-Term Investment - Short-term investments are classified as available-for-sale based on the Company's intended use. Differences, if any, between amortized cost and fair value representing unrealized holding gains or losses are recorded as a component of stockholders' equity as accumulated other comprehensive income/loss. Gains and losses on sales of investments are determined on a specific identification basis. At June 30, 1998, the Company's short-term investment consisted of one certificate of deposit, the cost of which approximated market. No investments were sold in the periods presented. Inventories - Inventories are stated at the lower of cost (first-in, first-out) or market. As a result of increased price pressure and weak demand from component manufacturers supplying the personal computer markets as well as an overall decline in the global semiconductor market, the Company included in cost of sales in 1998 a charge of approximately $8,500,000 to reduce inventory to net realizable value. Property and Equipment - Property and equipment are stated at cost. Depreciation and amortization are computed using the straight-line method based on the estimated useful lives of the assets (three to thirty years) or the lease term, if shorter. Long-Lived Assets - The Company evaluates long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Revenue Recognition - Sales are generally recognized upon shipment. Provisions are made for warranty costs, sales returns and price protection. Major Customers - No one customer accounted for more than 10% of net sales in fiscal 1996 and 1998, while one customer accounted for 11% of net sales in fiscal 1997. At June 30, 1997, two customers accounted for 14% and 15% of accounts receivable. At June 30, 1998, one customer accounted for 17% of accounts receivable. Stock-Based Compensation - The Company accounts for stock-based awards to employees under Statement of Financial Accounting Standards ("SFAS") No. 123, Accounting for Stock-Based Compensation, and as allowed in that statement, they measure compensation using the intrinsic value method in accordance with Accounting Principles Board Opinion ("APB") No. 25, Accounting for Stock Issued to Employees. Income Taxes - The Company accounts for income taxes under an asset and liability approach. Deferred tax liabilities are recognized for future taxable amounts and deferred tax assets are recognized for future deductible amounts. Recently Issued Accounting Standards - In June 1998, the Financial Accounting Standards Board issued SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities. This statement requires companies to record derivatives on the balance sheet as assets or liabilities, measured at fair value. Gains or losses resulting from changes in the values of those derivatives would be accounted for depending on the use of the derivative and whether it qualifies for hedge accounting. SFAS No. 133 will be effective for the Company's fiscal year 10 ending June 30, 2000. Management believes that this statement will not have a significant impact on the Company's financial position, results of operations or cash flows. In June 1997, the Financial Accounting Standards Board issued SFAS No. 130, Reporting Comprehensive Income and No. 131, Disclosures About Segments of an Enterprise and Related Information, which require the Company to report and display certain information related to comprehensive income and operating segments, respectively. Both statements are effective for fiscal years beginning after December 15, 1997. Accordingly, the Company will adopt SFAS No. 130 and SFAS No. 131 starting with its fiscal year ending June 30, 1999. Management believes that these statements will not have a significant impact on the Company's financial position, results of operations or cash flows. 2.

Borrowing Arrangements In 1997, the Company paid off its note payable of approximately $5.7 million using amounts received from the Parent company. The note bore interest at 10.25% and was collateralized by land, building, and related personal property. In 1998, the Company converted the $5.7 million owed to the Parent to common stock (Note 10). 4. Leases The Company owns both its corporate headquarters and its wafer fabrication facilities. Both facilities are in Garden Grove, California. The Company leases certain other facilities and equipment under operating lease agreements which expire at various dates through 2001. Rental expense charged to operations was approximately $424,000, $264,000 and $189,000 in 1996, 1997 and 1998, respectively. Future minimum lease payments at June 30, 1998 are as follows (in thousands): Year Ending June 30 1999........................................ $38 2000........................................ 38 2001........................................ 20 --- Total minimum lease payments.................... $96 === 5. Contingencies The Company is a party to certain legal claims in the normal course of its operations. While the results of such claims cannot be predicted with any certainty, management, after consultation with legal counsel, believes that the final outcome of such matters will not have a material adverse effect on the Company's financial statements. 6. Stockholders' Equity Preferred Stock At June 30, 1997 and 1998, all outstanding shares of the Company's Series A preferred stock were held by the Parent. Significant terms of the outstanding preferred stock are as follows: . Each share of preferred stock is convertible into one share of common stock at any time at the option of the holder (subject to adjustment for events of dilution). Conversion is mandatory upon the vote of a majority of the preferred stockholders. . Each share has voting rights equivalent to the number of shares of common stock into which it is convertible. . In the event of merger, liquidation, dissolution or winding up of the Company, preferred Series A stockholders are entitled to receive $2.00 per share for Series A prior to any distribution to the common stockholders. 12 . Holders of preferred stock are entitled to receive, when and if declared, annual dividends of $0.16 per share, adjusted for any stock dividends, combinations or splits. Common Stock At June 30, 1997 and 1998, the Parent company held 2,000,000 and 4,000,000 shares of the Company's common stock, respectively. Significant terms of the common stock are as follows: . Each share entitles the holder to one vote. . In the event of liquidation, dissolution or winding up of the Company, common stockholders are entitled to receive $0.50 per share after all payments have been made to the holders of Series A preferred stock. All remaining assets will then be distributed ratably among the common and preferred stockholders. At June 30, 1998, the Company had reserved shares of common stock as follows: Conversion of outstanding preferred stock............. 6,000,000 Employee stock option plan............................ 2,307,665 --------- 8,307,665 ========= Employee Stock Option Plan Under the Company's 1993 amended and restated stock option plan, 2,000,000 shares of common stock have been authorized for the grant of incentive or nonstatutory stock options. In 1997, the Company increased the number of authorized shares to 2,500,000. Stock options must be granted at not less than 110% of fair market value on the date of grant to employees or consultants who own more than 10% of the voting power of all classes of stock and not less than 100% of fair market value on the date of grant for all other employees or consultants. Stock options generally have vesting periods of four years and are exercisable as they vest and for a period not to exceed ten years from the date of issuance. 13 A summary of stock option activity is as follows: Weighted Number Average of Exercise Shares Price ------ ----- Outstanding, July 1, 1995 (486,800 exercisable at a weighted average price of $0.52)................................ 1,783,500 $1.38 Granted (weighted average fair value of $0.40).................... 60,000 2.65 Exercised.........................................................

(268,275) 1.90 --------- Outstanding, June 30, 1998........................................ 1,763,990 $2.61 ========= At June 30, 1998, 543,675 options were available for future grant. The following table summarizes information as of June 30, 1998 concerning options outstanding: Options Outstanding Options Exercisable ------------------------------------- --------------------------- Weighted Average Weighted Remaining Average Exercise Number Contractual Life Number Exercise Prices Outstanding (Years) of Shares Price ------ ------------ ------- --------- ----- $ 0.50 125,000 5.0 125,000 $0.50 0.80 115,600 5.7 115,600 0.80 2.65 685,390 7.1 409,165 2.65 3.15 838,000 9.1 107,500 3.15 --------- ------- 1,763,990 7.9 757,265 $2.08 ========= ======= SFAS No. 123, Accounting for Stock-Based Compensation, requires the disclosure of pro forma net income (loss) had the Company adopted the fair value method of accounting for stock options. Under SFAS No. 123, the fair value of stock-based awards to employees is calculated through the use of option pricing models, even though such models were developed to estimate the fair value of freely tradable, fully transferable options without vesting restrictions, which significantly differ from the Company's stock option awards. These models also require subjective assumptions, including expected time to exercise, which greatly affect the calculated values. The Company's calculations were made using the minimum value method with the following weighted average assumptions: expected life of three years for 1996 and two years for 1997 and 1998; risk-free interest rates of 5.6% for 1996 and 1997 and 5.4% for 1998; and no 14 dividends during the expected term. The Company's calculations are based on a single option valuation approach, and forfeitures are recognized as they occur. If the computed fair values of the 1996, 1997 and 1998 awards had been amortized to expense over the vesting period of the awards, pro forma net income (loss) would have been (in thousands) $1,348, $3,780 and $(6,986) in 1996, 1997 and 1998, respectively. Other Option Arrangements In 1997, the Company issued 54,000 options to a consultant. The Company is recording a compensation charge of approximately $42,000 over the vesting period of the options based on the intrinsic value of the options at the date of grant. Compensation expense of approximately $8,000 and $10,000 was recorded in 1997 and 1998, respectively. 7. Income Taxes The results of operations of the Company have historically been included in the Parent company's consolidated tax return. The Company has a tax sharing agreement with the Parent which generally allocates tax attributes to the Company. The agreement also provides for the Parent to pay taxes on behalf of the Company. At June 30, 1997 and 1998, taxes receivable and taxes payable were with the Parent company. The provision (benefit) for income taxes, net deferred tax assets and other tax attributes have been computed as if the Company were a separate corporate taxpayer. The provision (benefit) for income taxes consist of (in thousands): Years Ended June 30, ------------------------------- 1996 1997 1998 ---- ---- ---- Current income taxes: Federal........................... $ 781 $2,126 $ (905) State............................. 1 29 6 ----- ------ ------- 782 2,155 (899) ----- ------ ------- Deferred income taxes: Federal...........................

Employee Benefit Plan In 1994, the Company established a 401(k) plan which provides for retirement and certain other benefits to the Company's employees and their beneficiaries. The Company, under the plan, makes matching contributions up to $300 per employee. The 401(k) plan is administered under a written plan and trust agreement entered into between the Company and the Company's designated trustee. Company contributions were approximately $45,000, $52,000 and $42,000 for 1996, 1997 and 1998, respectively. 10. Related Party Transactions At June 30, 1997 and 1998, the Parent company held six million shares of the Company's preferred stock and two million and four million shares of the Company's common stock, respectively. In 1998, the Company converted $5.7 million of debt owed to the Parent into common stock at a price of $3.15 per share. The Company is allocated an overhead charge based on planned revenue at the beginning of each year from the Parent, which is included in general and administrative expenses. Management believes this allocation methodology to be a reasonable basis for the charges. These charges were approximately $819,000, $1,125,000, and $1,200,000 for the years ended June 30, 1996, 1997 and 1998, respectively. As described in the preceding paragraphs and Notes 6 and 7, the Company has significant transactions with the Parent. Accordingly, the accompanying financial statements may not be 16 indicative of the financial condition or results of operations had the Company operated without such affiliations. 11. Subsequent Events On April 14, 1999, SymmetriCom, Inc. (SymmetriCom), consummated the sale of Linfinity Microelectronics Inc. to Microsemi Corporation ("Microsemi"). All preferred stock, common stock, and outstanding options of Linfinity were exchanged for cash on a basis defined by the Agreement and Plan of Reorganization. The total purchase price was approximately $24 million. Microsemi was incorporated in Delaware in 1960 and is a multinational supplier of high-reliability discrete semiconductors, surface mounted assemblies and high-reliability screening and testing services. 17 LINFINITY MICROELECTRONICS INC.

(A Controlled Subsidiary of SymmetriCom, Inc.) NOTES TO FINANCIAL STATEMENTS Nine Months Ended March 31, 1999 (Unaudited) 1. Basis of Presentation The financial statements included herein have been prepared by Linfinity Microelectronics Inc. (the "Company"), without audit. Certain information and footnote disclosures, normally included in the annual financial statements prepared in accordance with generally accepted accounting principles, have been condensed or omitted. These financial statements should be read in conjunction with the financial statements and notes thereto for the year ended June 30, 1998 included in this Form 8-K/A. In the opinion of the management, these unaudited statements contain all adjustments (consisting only of normal recurring adjustments) necessary to present fairly the financial position of the Company at March 31, 1999, the results of operations for the nine-month period then ended and its cash flows for the nine-month period then ended. The results of operations for the period presented are not necessarily indicative of those that may be expected for the full year. The Company has significant transactions with its parent, SymmetriCom, Inc. Accordingly, the accompanying financial statements may not be indicative of the financial condition or results of operations had the Company operated without such affiliations. 2. Inventories Inventories are stated at the lower of cost (first-in, first-out) or market. Inventories at March 31, 1999 and 1998 consist of: 1999 1998 ---- ---- Raw materials........................................................ $ 607 $ 645 Work-in-process...................................................... 3,306 4,188 Finished goods....................................................... 1,984 376 ------ ------ $5,897 $5,209 ====== ====== 3. Recent Accounting Pronouncements In June 1998, the Financial Accounting Standards Board issued SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities. This statement requires companies to record derivatives on the balance sheet as assets or liabilities, measured at fair value. Gains or losses resulting from changes in the values of those derivatives would be accounted for depending on the use of the derivative and whether it qualifies for hedge accounting. SFAS No. 133 will be effective for the Company's fiscal year ending June 30, 2000. Management believes that this statement will not have a significant impact on the Company's financial position, results of operations or cash flows. 23 In June 1997, the Financial Accounting Standards Board issued SFAS No. 130, Reporting Comprehensive Income and No. 131, Disclosures About Segments of an Enterprise and Related Information, which require the Company to report and display certain information related to comprehensive income and operating segments, respectively. Both statements are effective for fiscal years beginning after December 15, 1997. Accordingly, the Company will adopt SFAS No. 130 and SFAS No. 131 starting with its fiscal year ending June 30, 1999. Management believes that these statements will not have a significant impact on the Company's financial position, results of operations or cash flows. 4. Contingencies The Company is a party to certain legal claims in the normal course of its operations. While the results of such claims cannot be predicted with any certainty, management, after consultation with legal counsel, believes that the final outcome of such matters will not have a material adverse effect on the Company's financial position and results of operations. 5. Subsequent Event On April 14, 1999, SymmetriCom, Inc. (SymmetriCom), consummated the sale of Linfinity Microelectronics Inc. to Microsemi Corporation ("Microsemi"). All preferred stock, common stock, and outstanding options of the Company were exchanged for cash on a basis defined by the Agreement and Plan of Reorganization. The total purchase price was approximately $24 million. Microsemi was incorporated in Delaware in 1960 and is a multinational supplier of high-reliability discrete semiconductor, surface mounted assemblies and high- reliability screening and testing services. 24 (b) Unaudited Pro Forma Condensed Financial Information. On April 14, 1999, Microsemi Corporation ("Microsemi" or the "Company") acquired all of the outstanding capital stock of Linfinity Microelectronics, Inc. ("Linfinity") for $24,100,000 in cash. The acquisition has been accounted for under the purchase method of accounting. Accordingly, the results of operations will be included with the Company's beginning at the acquisition date. The purchase price resulted in an excess of the cost of the acquisition over the fair value of the net assets acquired of $29,000. Such excess is being amortized on a straight-line basis over 10 years. The preliminary purchase price allocation is based on an independent appraisal and management's estimates. The purchase price allocation is subject to further refinement and change over the next year. The Unaudited Pro Forma Condensed Balance Sheet at April 4, 1999 combines the historical balance sheets of the Company and Linfinity as if the acquisition had occurred on April 4, 1999, after giving effect to certain adjustments described in the accompanying Notes to Unaudited Pro Forma Condensed Financial Information. The Unaudited Pro Forma Condensed Income Statements for the year ended September 27, 1998 and for the six-months ended April 4, 1999 present the combined results of operations of the Company and Linfinity as if the acquisitions had occurred on September 29, 1997, after giving effect to certain adjustments described in the accompanying Notes to Unaudited Pro Forma Condensed Financial Information. The following Unaudited Pro Forma Condensed Financial Information is presented for illustrative purposes only. It is not necessarily indicative of the consolidated financial position or results of operations for future periods or the results that actually would have been realized had the Company and Linfinity been a consolidated company during the specified periods. The Unaudited Pro Forma Condensed Financial Information, including the notes thereto, is qualified in its entirety by reference to, and should be read in conjunction with the historical consolidated financial statements and the notes thereto, which were previously reported in the Company's Annual Report on Form 10-K for the year ended September 27, 1998 and the Quarterly Report on Form 10-Q for the quarter ended April 4, 1999. This report on Form 8-K/A may contain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Actual results could differ materially from these forward-looking statements as a result of the risk factors stated in the Company's periodic reports both previously and hereafter filed with the Securities Exchange Commission.

Basis of Presentation On April 14, 1999, Microsemi Corporation ("Microsemi") completed the acquisition of all of the outstanding capital stock of Linfinity Microelectronics, Inc. ("Linfinity") from SymmetriCom, Inc. ("SymmetriCom"). The transaction was completed pursuant to the Agreement and Plan of Reorganization dated February 10, 1999 by and among Microsemi, Microsemi-Linfinity Acquisition Corporation, SymmetriCom and Linfinity. Microsemi paid approximately $24,100 in cash. All preferred stock, common stock, and outstanding options of Linfinity were exchanged for cash on a basis defined by the Agreement and Plan of Reorganization. In addition, Linfinity was transferred certain liabilities. Of the purchase price, approximately $1,100 was deposited into an escrow account to provide funds for potential claims for indemnification of Microsemi under certain provisions of the Agreement and Plan of Reorganization. The unaudited pro forma condensed balance sheet combines Microsemi's unaudited condensed balance sheet amounts as of April 4, 1999 with Linfinity's unaudited condensed balance sheet amounts as of March 31, 1999 and gives effect to the acquisition as if the transaction had taken place on April 4, 1999. The unaudited pro forma condensed income statement is presented using Microsemi's unaudited condensed income statement for the six months ended April 4, 1999 combined with Linfinity's unaudited condensed income statement for the six months ended March 31, 1999 and gives effect to the acquisition as if the transaction had occurred on September 29, 1997. Additionally, the presentation includes Microsemi's condensed income statement for the fiscal year ended September 27, 1998 combined with Linfinity's condensed income statement for the fiscal year ended June 30, 1998 and gives effect to the acquisition as if the transaction had taken place on September 29, 1997. The results of operations for the six months ended April 4, 1999 are not necessarily indicative of the results to be expected for the full year. There were no transactions between Microsemi and Linfinity during the period presented and there are no significant differences between the accounting policies of Microsemi and Linfinity. The unaudited pro forma condensed financial information should be read in conjunction with the consolidated financial statements and notes thereto of Microsemi, which were previously reported in Microsemi's Annual Report on Form 10-K for the year ended September 27, 1998 and its Quarterly Report on Form 10-Q for the quarter ended April 4, 1999, and with the financial statements and notes thereto of Linfinity included elsewhere in this Form 8-K/A. These pro forma statements are based on such consolidated financial statements after giving effect to the transaction under the purchase method of accounting and the assumptions and adjustments described below. The pro forma information does not purport to be indicative of the results which would have been reported if the purchase had been in effect for the periods presented or which may result in the future. 30 Note 2. Pro Forma Adjustments The pro forma adjustments are based on a preliminary allocation of the purchase price to the assets acquired and liabilities assumed. The allocation of the purchase price is based on an independent appraisal of certain assets as well as management estimates of fair value. Pro forma adjustments relating to the acquisition in the unaudited pro forma financial information are summarized as follows: As of Ref Adjustment April 4, 1999 --- ---------- ------------- Cash (a) To eliminate asset which was not purchased by Microsemi $ (2,868) To record additional cash proceeds from new bank financing 2,684 -------- (184) -------- Current deferred tax assets (b) To eliminate tax asset which was not purchased by Microsemi (4,100) Other assets (c) To record finance fees for loan used in acquisition 450 Intangible assets (d) To record the allocation of the purchase price to certain intangible assets and goodwill 4,590 -------- Increase in total assets...................................................................................... $ 756 ======== Notes payable to bank and (e) To record net proceeds under new loan used to finance the others purchase of Linfinity 5,733 Current maturity of long-term (f) To record net proceeds under new loan used to finance the debt purchase of Linfinity 2,000 Due to Symmetricom (g) To eliminate liability which was not assumed by Microsemi (1,694) Long-term debt (h) To record net proceeds under new loan used to finance the purchase of Linfinity 19,500 Other long-term liabilities (i) To eliminate liabilities which were not assumed by Microsemi (1,762) Stockholders' equity (j) To eliminate the net assets of Linfinity (23,021) -------- Increase in total liabilities and stockholders' equity..................................................................................... $ 756 ======== Year Ended September 27, Ref Adjustment 1998 --- ---------- ------------- Amortization of goodwill and (k) To record amortization of goodwill and other intangible intangible assets assets 376 To record write-off of IPR&D 1,950 -------- 2,326 -------- Interest and other expenses (l) To record interest expense in connection with new loans 2,179 Provision (benefit) for income (m) To record the tax affects of the above adjustments (1,712) taxes -------- Decrease in net income (loss)................................................................................. 2,793 ======== 31 Six-Months Ended April 4, Ref Adjustment 1999 --- ---------- ---------- Amortization of goodwill and (n) To record amortization of goodwill and other intangible assets 188 intangible assets Interest and other expenses (o) To record interest expense in connection with new loans 1,090 Provision (benefit) for income taxes (p) To record the tax affects of the above adjustments (473) ------- Decrease in net income (loss)....................................................................................... 805 ======= This Current Report on Form 8-K/A may contain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Actual results could differ materially from these forward-looking statements as a result of the risk factors set forth in Microsemi's periodic reports both previously and hereafter filed with the Securities Exchange commission. Note 3. Pro Forma Earnings Per Share Basic pro forma earnings per share was calculated based on equivalent shares of Microsemi's Common Stock outstanding at April 4, 1999 and September 27, 1998.
