OSI SYSTEMS, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES General. OSI Systems, Inc. and its subsidiaries (collectively, the "Company") is a vertically integrated worldwide provider of devices, subsystems and end- products based on optoelectronic technology. The Company designs and manufactures optoelectronic and devices and value-added subsystems for original equipment manufacturers in a broad range of applications, including security, medical diagnostics, telecommunications, gigabit ethernet and fiber optics, gaming, office automation, aerospace, computer peripherals and industrial automation. In addition, the Company utilizes its optoelectronic technology and design capabilities to manufacture security and inspection products that it markets worldwide to end users under the "Rapiscan", "Secure" and "Metor" brand names. These products are used to inspect people, baggage, cargo and other objects for weapons, explosives, drugs and other contraband. The Company also manufactures and sells bone densitometers, which are used to provide bone loss measurements in the diagnosis of osteoporosis. Consolidation. The consolidated financial statements include the accounts of OSI Systems, Inc. and its majority-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. The consolidated balance sheet as of March 31, 2001, the consolidated statements of operations for the three-month and nine-month periods ended March 31, 2001 and 2000 and the consolidated statements of cash flows for the nine month periods ended March 31, 2001 and 2000 have been prepared by the Company, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (the "Commission"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations. However, in the opinion of management all adjustments, consisting of only normal and recurring adjustments, necessary for a fair presentation of the financial position and the results of operations for the periods presented have been included. These consolidated financial statements and the accompanying notes should be read in conjunction with the audited consolidated financial statements and accompanying notes for the fiscal year ended June 30, 2000 included in the Company's Annual Report on Form 10K as filed with the Commission on September 27, 2000. The results of operations for the nine months ended March 31, 2001 are not necessarily indicative of the results to be expected for the fiscal year ending June 30, 2001. Certain amounts related to the prior periods have been reclassified to confirm to the current year presentation. -6-

Recent Developments - In August 2000, the Company acquired substantially all the assets of Square One Technology for total consideration consisting of: $228,000 in cash, a $30,000 advance for future royalties, the return of the Square One stock held by the Company with a carrying value of $259,000, and an agreement to pay royalties equal to ten percent of net sales of the Square One products in the next five years, up to a maximum of $1.0 million. The cash consideration of $228,000 approximates the fair value of the tangible assets acquired. In September 2000, the Company acquired an additional equity interest, representing approximately 10% of the ownership of OSI Medical Inc., for $183,000. This amount was recorded as goodwill based on the estimated fair value of the underlying net assets and is being amortized over a period of twenty years. With this additional equity investment, the Company increased its common stock ownership in OSI Medical Inc. to approximately 64%. The Company sold all of the outstanding stock of its wholly owned subsidiary, Silicon Microstructures, Inc. ("SMI") to Elmos Semiconductor AG of Germany for $6.0 million in cash. In connection with the transaction, the Company's UDT Sensors, Inc. ("UDT") subsidiary sold certain capital equipment to SMI for $462,000 in cash. The transaction was completed on March 31, 2001. The sale agreement also includes a three year commitment from UDT to supply four inch silicon foundry wafers to SMI and to dedicate limited manufacturing facilities to be used by SMI, for its etching operations. The total pre-tax gain on the transaction was $3.0 million. In April 2001, as a result of the acquisition of a company in which the Company had an equity investment of $300,000, the Company received a total consideration of $1.4 million. This resulted a pre-tax gain of $1.1 million and will be recorded in the quarter ending June 30, 2001. This consideration does not include a hold back of approximately $167,000. New Accounting Pronouncements - In December 1999, the Securities and Exchange Commission issued Staff Accounting Bulletin 101, Revenue Recognition In Financial Statements ("SAB 101"). SAB 101 provides guidance on applying generally accepted accounting principles to revenue recognition in financial statements. The Company will adopt SAB 101 as required in the fourth quarter of fiscal 2001. The Company is currently evaluating the impact of adopting SAB 101, and does not expect it to have a material impact on the Company's financial position or result of operations. Effective July 1, 2000, the Company adopted FASB Statement No. 133, Accounting for Derivative Instruments and Hedging Activities ("FAS 133"). FAS 133 requires that all derivative financial instruments, such as foreign exchange contracts, be recognized in the financial statements and measured at fair value regardless of the purpose or intent for holding them. Changes in the fair value of derivative financial instruments are either recognized periodically in income or shareholders' equity (as a component of comprehensive income), depending on whether the derivative is being used to hedge changes in fair value or cash flows. The adoption of FAS 133 did not have a material effect on the Company's financial position or result of operations for the quarter and nine months ended March 31, 2001. Financial Instruments - The Company enters into forward foreign exchange contracts -7-

principally to hedge currency fluctuation in transactions denominated in foreign currencies, thereby limiting the Company's risk that would otherwise result from changes in exchange rates. The periods of the forward foreign exchange contracts correspond to the periods of the hedged transactions. The Company does not use the contracts for trading purposes. As of March 31, 2001, the total notional amount of all outstanding foreign currency contracts was $1.4 million. The estimated fair value of foreign currency contracts was not material. Inventory. Inventory is stated at the lower of cost or market; cost is determined on the first-in, first-out method. Inventory at March 31, 2001 and June 30, 2000 consisted of the following (in thousands): March 31, June 30, 2001 2000 Raw Materials.................... $15,403 $16,877 Work-in-process.................. 6,835 6,619 Finished goods................... 9,518 7,424 ------- ------- Total......................... $31,756 $30,920 ======= ======= Earnings Per Share. Earnings per common share is computed using the weighted average number of shares outstanding during the period. Earnings per common share-assuming dilution, is computed using the weighted average number of shares outstanding during the period and dilutive common stock equivalents from the Company's stock option plans. The following table reconciles the numerator and denominator used in calculating earnings per common share and earnings per common share-assuming dilution. -8-

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations. Statements in this report that are forward-looking are based on current expectations, and actual results may differ materially. Forward-looking statements involve numerous risks and uncertainties that could cause actual results to differ materially, including, but not limited to, the possibilities that the demand for the Company's products may decline as a result of possible changes in general and industry specific economic conditions and the effects of competitive pricing and such other risks and uncertainties as are described in this report on Form 10-Q and other documents previously filed or hereafter filed by the Company from time to time with the Securities and Exchange Commission. Results of Operations Revenues. Revenues consist of sales of optoelectronic and pressure sensor devices, medical imaging systems and security and inspection products. Revenues are recorded net of all inter-company transactions. Revenues decreased by 7.5% to $29.4 million for the three months ended March 31, 2001, compared to $31.8 million for the comparable prior year period. For the nine months ended March 31, 2001, revenues decreased by 1.2% to $82.3 million from $83.2 million for the comparable prior year period. Revenues for the three months ended March 31, 2001 from optoelectronic devices, value added subsystems and medical imaging systems, were $16.7 million, compared to $17.9 million for the comparable prior year period and revenues from security and inspection products were $12.7 million compared to $13.9 million for the comparable prior year period. Revenues for the nine months ended March 31, 2001 from optoelectronic devices, value added subsystems and medical imaging systems were $44.2 million, compared to $46.7 million for the comparable prior year period and revenues from security and inspection products were $38.1 million, compared to $36.5 million for the comparable prior year period. The decrease in revenues from sales of optoelectronic devices, value added subsystems and medical imaging systems for the quarter and nine months ended March 31, 2001 was primarily due to decreased sales of the discontinued product line of data/video projector systems and was offset in part by increased sales of fiber optics and sales to the weapon simulation market. Revenues from the sales of data/video projector systems for the three and nine months ended March 31, 2001 were $0 and $1.0 million, compared to $5.5 million and $7.6 million respectively, for the comparable prior year periods. The decrease in revenues from sale of security and inspection products for the quarter was primarily due to the timing of the shipment of large orders. Gross Profit. Cost of goods sold consists of material, labor and manufacturing overhead. Gross profit decreased by 5.7% to $7.9 million for the three months ended March 31, 2001, compared to $8.3 million for the comparable prior year period. For the nine months ended March 31, 2001, gross profit increased by 0.7% to $22.8 million, compared to $22.6 million for the comparable prior year period. As a percentage of revenues, gross -11-

profit increased in the quarter and nine months to 26.8% and 27.7% this year, from 26.3% and 27.2% last year, respectively. The decrease in gross margin in the quarter was due to lower sales and an increase in gross margin as a percentage of revenues was due to discontinuation of the data/video projector systems product line, which had a lower gross margin. Selling, General and Administrative. Selling, general and administrative expenses consisted primarily of compensation paid to sales, marketing and administrative personnel, and professional service fees and marketing expenses. For the three months ended March 31, 2001, such expenses increased 6.7% to $5.3 million, compared to $4.9 million for the comparable prior year period. For the nine months ended March 31, 2001, such expenses increased by 8.5% to $16.5 million, compared to $15.2 million for the comparable prior year period. As a percentage of revenues, selling, general and administrative expenses increased in the quarter and nine months to 17.9% and 20.0% this year, from 15.5% and 18.2% last year, respectively. The increase in expenses for the quarter and nine months was primarily due to increased administrative expenses, legal and professional fees and an increase in provision for doubtful receivables, offset in part by proceeds of $409,000 from the settlement of certain litigation. Research and Development. Research and development expenses include research related to new product development and product enhancement expenditures. For the three months ended March 31, 2001, such expenses decreased 15.6% to $1.8 million, compared to $2.1 million for the comparable prior year period. For the nine months ended March 31, 2001, such expenses decreased 11.0% to $5.0 million, compared to $5.6 million for the comparable prior year period. As a percentage of revenues, research and development expenses decreased in the quarter and nine month periods to 6.0% and 6.1% this year from 6.6% and 6.7% last year, respectively. The decrease in expenses for the quarter and nine months ended March 31, 2001 was primarily due to deploying certain research and development personnel to the manufacturing of products, offset in part by increased research spending for medical and fiber optic products. Restructuring Costs. In August 1999, the Company decided to close the operations of Osteometer in Denmark, and relocate certain of these operations to the Company's U.S. facilities. For the nine months ended March 31, 2000, the Company recorded restructuring costs of $1.9 million related to the closure of the Osteometer facility in Denmark. These costs were associated primarily with the termination of certain employees, commitments and other facility closure costs. The Company has completed the closure of the Osteometer facility in Denmark and does not anticipate any future expenses. Income (Loss) from Operations. For the three months ended March 31, 2001, the Company had income from operations of $718,000 compared to $1.2 million for the three months ended March 31, 2000. For the nine months ended March 31, 2001, the Company had income from operations of $937,000 compared to a loss from operations of $451,000 for the comparable prior year period. Excluding the non- recurring restructuring costs of -12-

$1.9 million in the nine months ended March 31, 2000, income from operations for the nine months ended March 31, 2000 was $1.4 million. Income from operations for the three months ended March 31, 2001 decreased due to a lower gross margin, increased selling, general and administration expenses and was offset in part by reduced research and development expenses. Excluding the restructuring charge of $1.9 million in the period ended March 31, 2000, income from operations for the nine months ended March 31, 2001 decreased due to increased selling, general and administrative expenses and was offset in part by reduced research and development expenses. Interest Expense. For the three months ended March 31, 2001, the Company incurred net interest expense of $276,000, compared to net interest expense of $201,000 for the three months ended March 31, 2000. For the nine months ended March 31, 2001, the Company incurred net interest expense of $865,000, compared to net interest expense of $500,000 for the nine months ended March 31, 2000. The increase in net interest expense for the three and nine months ended March 31, 2001 was due to higher average amount outstanding on the Company's lines of credit and a reduction in short term investments which were used for working capital and acquisitions. Gain on Sale of Subsidiary. On March 31, 2001, the Company sold all of the outstanding stock of its wholly owned subsidiary SMI to Elmos Semiconductor AG of Germany for $6.0 million in cash resulting in a gain of $3.0 million. In addition, as a part of the agreement, $2.2 million of the accounts payable by SMI to the Company as a result of intercompany transactions was converted to a note receivable payable by the buyer over a period of four and a half years. Provision (Benefit) for Income Taxes. Provision for income taxes increased to $869,000 for the three months ended March 31, 2001, compared to $284,000 for the three months ended March 31, 2000. For the nine months ended March 31, 2001, the Company had an income tax provision of $799,000 compared to a income tax benefit of $29,000 for the nine months ended March 31, 2000. The change in provision (benefit) for income taxes was due to a mix in income from U.S. and foreign operations. Net Income (Loss). For the reasons outlined above, the Company had net income of $2.5 million and $2.4 million for the three and nine months ended March 31, 2001, compared to net income of $841,000 and a net loss of $385,000 for the three and nine months ended March 31, 2000, respectively. Liquidity and Capital Resources The Company's operations used net cash of $1.7 million during the nine months ended March 31, 2001. The amount of net cash used by operations reflects increases in accounts receivable, inventory, prepaids, and reduction in accounts payables. Net cash used in operations was offset in part by an increase in accrued payroll and related expenses, income taxes payable, advances from customers, and reduction in other receivables. The increase in accounts receivable is mainly due to the timing of shipments of certain large -13-

contracts. The increase in inventory is due to a change in product mix and a longer intercompany in transit time due to certain manufacturing being moved to Malaysia from the United States and the United Kingdom. Net cash provided by investing activities was $2.9 million for the nine months ended March 31, 2001, compared to net cash used in investing activities of $1.1 million for the nine months ended March 31, 2000. In the nine months period ended March 31, 2001, net cash provided by investing activities reflects cash received from the sale of SMI and the sale of property and equipment and was offset in part by cash used in business acquisitions and the purchase of property and equipment. In the nine months ended March 31, 2000, the net cash used in investing activities reflects primarily cash used in business acquisitions and the purchase of property and equipment and was offset in part by proceeds received from the sale of marketable securities. Net cash used in financing activities was $4.5 million for the nine months ended March 31, 2001, compared to net cash provided by financing activities of $4.0 million in the nine months ended March 31, 2000. During the nine months ended March 31, 2001, net cash used in financing activities resulted primarily due to the purchase of the Company's common shares pursuant to its stock repurchase program and repayment of borrowings under the Company's lines of credit. In March 1999, the Company announced a stock repurchase program of up to 2,000,000 shares of its common stock. Through May 10, 2001, the Company repurchased 935,500 shares at an average price $4.60 per share. The stock repurchase program did not have a material effect on the Company's liquidity and is not expected to have a material effect on liquidity in subsequent quarters. The Company retired the repurchased shares. The shares are included as a deduction from issued and outstanding common shares in the accompanying financial statements. In February 2001, the Company entered into a credit agreement with Sanwa Bank California. The agreement provides for a $12.0 million line of credit, which includes revolving line, letter of credit, acceptance and foreign exchange facilities. In addition, the Company has a $10.5 million term loan. The Company anticipates that current cash balances, anticipated cash flows from operations and current borrowing arrangements will be sufficient to meet its working capital and capital expenditure needs for the foreseeable future. Foreign Currency Translation. The accounts of the Company's operations in Singapore, Malaysia, England, Norway, Denmark, Finland and Canada are maintained in Singapore dollars, Malaysian ringgits, U.K. pounds sterling, Norwegian kroner, Danish kroner, Finnish markka and Canadian dollars, respectively. Foreign currency financial statements are translated into U.S. dollars at current rates, with the exception of revenues, costs and expenses, which are translated at average rates during the reporting period. Gains and losses resulting from foreign currency transactions are included in income, while those resulting from translation of financial statements are excluded from income and -14-

accumulated as a component of accumulated other comprehensive income. Net foreign currency transaction losses of approximately $258,000 and $131,000 were included in the Company's results for the nine months ended March 31, 2001 and 2000, respectively. Inflation. The Company does not believe that inflation has had a material impact on its results of operations for the nine months ended March 31, 2001. Item 6. Exhibits and Reports of Form 8-K a.

Within the foregoing limits, the Borrower may borrow, partially or wholly prepay, and reborrow under this Section 2.1. Proceeds of the Line of Credit shall be used for general working capital purposes. 2.1.2 Making Line Advances: Each Advance shall be conclusively deemed to have been made at the request of and for the benefit of the Borrower (i) when credited to any deposit account of the Borrower maintained with the Bank or (ii) when paid in accordance with the Borrower's written instructions.

(ii) Fixed Rate Advances: A fixed rate per annum quoted by the ------------------- Bank for 30, 60, 90 or 180 days or for such other period of time that the Bank may quote and offer (provided that any such period of time does not extend beyond the Expiration Date) (the "Interest Period") for Advances in the minimum amount of $100,000.00. Such interest rate shall be a percentage equal to the Applicable Margin plus the rate which the Bank determines in its sole and absolute discretion to be equal to the Bank's cost of acquiring funds (adjusted for any and all assessments, surcharges and reserve requirements pertaining to the borrowing or purchase by the Bank of such funds) in an amount approximately equal to the amount of the relevant Advance and for a period of time approximately equal to the relevant Interest Period (the "Fixed Rate"). Advances based upon the Fixed Rate are hereinafter referred to as "Fixed Rate Advances". (iii) LIBOR Advances: A fixed rate quoted by the Bank for one -------------- week, 1, 2, 3, or 6 months or for such other period of time that the Bank may quote and offer (provided that any such period of time does not extend beyond the Expiration Date) (the "LIBOR Interest Period") for Advances in the minimum amount of $100,000.00. Such interest rate shall be a percentage equal to the Applicable Margin plus the Bank's LIBOR Rate which is that rate determined by the Bank's Treasury Desk as being the arithmetic mean (rounded upwards, if necessary, to -6-

Interest on any Advance shall be computed on the basis of 360 days per year, but charged on the actual number of days elapsed. The Borrower hereby promises and agrees to pay interest in arrears on all Advances on the first calendar day of each month. If interest is not paid as and when it is due, it shall be added to the principal, become and be treated as a part thereof, and shall thereafter bear like interest. 2.1.5 Notice of Borrowing: Upon written or telephonic notice which shall be received by the Bank at or before 2:00 p.m. (California time) on a Business Day, the Borrower may borrow under the Line of Credit by requesting: (i) A Variable Rate Advance or Fixed Rate Advance: A Variable Rate --------------------------------------------- Advance or Fixed Rate Advance may be made on the day notice is received by the Bank; provided, however, that if the Bank shall not have received notice at or before 2:00 p.m. on the day such Advance is requested to be made, such Variable Rate Advance or Fixed Rate Advance may, at the Bank's option, be made on the next Business Day.

(ii) That interest on a Variable Rate Advance shall be adjusted to accrue at the LIBOR Rate; provided, however, that such notice shall be received by the Bank no later than two Business Days prior to the Business Day on which the Borrower requests that interest be adjusted to accrue at the LIBOR Rate. (iii) That interest on a Fixed Rate Advance shall continue to accrue at a newly quoted Fixed Rate or shall be adjusted to commence to accrue at the Variable Rate; provided, however, that such notice shall be received by the Bank no later than 2:00 p.m. on the last day of the Interest Period pertaining to such Fixed Rate Advance. If the Bank shall not have received notice (as prescribed herein) of the Borrower's election that interest on any Fixed Rate Advance shall continue to accrue at the newly quoted Fixed Rate as the case may be the Borrower shall be deemed to have elected that interest thereon shall be adjusted to accrue at the -7-

Variable Rate upon the expiration of the relevant Interest Period pertaining to such Advance. (iv) That interest on a Fixed Rate Advance shall accrue at a newly quoted LIBOR Rate or interest on a LIBOR Advance shall continue to accrue at a newly quoted Fixed Rate or LIBOR Rate or shall be adjusted to commence to accrue at the Variable Rate; provided, however, that such notice shall be received by the Bank no later than two Business Days prior to the last day of the relevant Interest Period or LIBOR Interest Period, as applicable. If the Bank shall not have received notice as prescribed herein of the Borrower's election that interest on any Fixed Rate Advance shall accrue interest at a newly quoted LIBOR Rate or at a newly quoted Fixed Rate pursuant to subparagraph (iii) hereinabove; or any LIBOR Advance shall continue to accrue at the newly quoted Fixed Rate or LIBOR Rate as the case may be, the Borrower shall be deemed to have elected that interest thereon shall be adjusted to accrue at the Variable Rate upon the expiration of the relevant Interest Period or LIBOR Interest Period pertaining to such Advance. 2.1.7 Prepayment: The Borrower may prepay any Advance in whole or in part, at any time and without penalty, provided, however, that: (i) any partial prepayment shall first be applied at the Bank's option, to accrued and unpaid interest and next to the outstanding principal balance; and (ii) during any period of time in which interest is accruing on any Advance on the basis of the LIBOR Rate or Fixed Rate, no prepayment shall be made except on a day which is the last day of the LIBOR Interest Period or Interest Period pertaining thereto. If the whole or any part of any LIBOR Advance or Fixed Rate Advance is prepaid by reason of acceleration or otherwise (except as described hereinabove), the Borrower shall, upon the Bank's request, promptly pay to and indemnify the Bank for all costs, expenses and any loss ( excluding loss of profit on any margin) actually incurred by the Bank and any loss (including loss of profit resulting from the re-employment of funds) deemed sustained by the Bank as a consequence of such prepayment and provided further, that any prepayment hereunder shall not be deemed to be an event of default. The Bank shall be entitled to fund all or any portion of its Advances in any manner it may determine in its sole discretion, but all calculations and transactions hereunder shall be conducted as though the Bank actually funded all Advances through the purchase of dollar deposits bearing interest at the same rate as U.S. Treasury securities in the amount of the relevant Advance and in maturities corresponding to the date of such purchase to the Expiration Date hereunder. 2.1.8 Indemnification for LIBOR Rate or Fixed Rate Costs: During any period of time in which interest on any Advance is accruing on the basis of the LIBOR Rate or Fixed Rate, the Borrower shall, withing 15 days of the Bank's written request, which request shall explain in reasonable detail the reason for such costs or payments, promptly pay to and reimburse the Bank for all costs incurred and payments made by the Bank by reason of any future assessment, reserve, deposit or similar requirement or any surcharge, tax or fee imposed upon the Bank or as a result of the Bank's compliance with any directive or requirement of any regulatory authority pertaining or relating to funds used by the Bank in quoting and determining the LIBOR Rate or Fixed Rate. Bank shall use its best efforts to provide Borrower in advance, with an estimate or any such costs which may potentially be incurred hereunder. 2.1.9 Conversion from LIBOR Rate or Fixed Rate to Variable Rate: In the event that the Bank shall at any time determine that the accrual of interest on the basis of the LIBOR Rate or Fixed Rate (i) has become infeasible because the Bank is unable to determine the LIBOR Rate or Fixed Rate due to the unavailability of U.S. Dollar deposits, contracts or certificates of deposit in an amount approximately equal to the amount of the relevant -8-

Advance and for a period of time approximately equal to the relevant LIBOR Interest Period or Interest Period as the case may be or (ii) is or has become unlawful by reason of the Bank's compliance with any new law, rule, regulation, guideline or order, or any new interpretation of any present law, rule, regulation guideline or order, then the Bank shall promptly give telephonic notice thereof (confirmed in writing) to the Borrower, in which event any Advance bearing interest at either the LIBOR Rate or Fixed Rate as the case may be shall be deemed to be a Variable Rate Advance and interest shall thereupon immediately accrue at the Variable Rate and shall continue at such rate until the Bank determines that the LIBOR Rate or Fixed Rate is no longer infeasible or unlawful. 2.2 THE TERM LOAN 2.2.1 The Term Loan: On terms and conditions as set forth herein, the Bank agrees to lend to the Borrower in one drawing, upon the Borrower's request therefore made prior to February 1, 2001, up to the maximum amount of $10,500,000.00 (the "Term Loan").

The Bank shall be entitled to fund all or any portion of the Term Loan in any manner it may determine in its sole discretion, but all calculations and transactions hereunder shall be conducted as though the Bank actually funded the Term Loan through the purchase of dollar deposits bearing interest at the same rate as U.S. Treasury securities in the amount of the Term Loan and in maturities corresponding to the date of such purchase to the Expiration Date hereunder. 2.2.8 Indemnification for LIBOR Rate or Fixed Rate Costs.

(iv) Prior to the issuance of each Letter of Credit, but in no event later than 10:00 a.m. (California time) on the day such Letter of Credit is to be issued (which shall be a Business Day), the Borrower shall deliver to the Bank a duly executed form of the Bank's standard form of application for issuance of a Letter of Credit with proper insertions.
