Item 7.01.    Regulation FD Disclosure.

On October 25, 2005, OSI Systems, Inc. (the "Company") announced that it had successfully completed the placing of approximately 20% of the equity in Spacelabs Healthcare, Inc. ("Spacelabs"), a newly formed Delaware corporation composed of the healthcare operations of the Company. The placing raised approximately $27 million net of expenses. The shares of common stock of Spacelabs will be listed on the AIM of the Lo (d) expenses or liabilities of any type whatsoever which have been paid directly to a Director by an insurance carrier under a policy of officers' and directors' liability insurance maintained by the Company; or (e) expenses and the payment of profits arising from the purchase and sale by a Director of securities in violation of Section 16(b) of the Securities Exchange Act of 1934, as amended, or any similar successor statute. APPLICATION OF US AND UK LEGISLATION The Company is incorporated under the laws of the State of Delaware, USA. Accordingly, a significant amount of the legislation in England and Wales regulating the operation of companies does not apply to the -------------------------------------------------------------------------------- 31 PART 2 -- RISK FACTORS -------------------------------------------------------------------------------- Company. In addition, the laws of the State of Delaware will apply in respect of the Company and these laws may provide for mechanisms and procedures that would not otherwise apply to companies incorporated in England and Wales. REGISTRATION REQUIREMENTS AND TAX RISKS RELATING TO THE ACQUISITION OF COMPANIES FROM OSI AND UDT SENSORS The Company has entered into a stock transfer agreement with OSI and UDT Sensors. Pursuant to this agreement OSI and UDT Sensors agreed to sell to the Company various companies owned at that time by OSI and UDT Sensors (as listed in paragraph 3.3 of Part 7). As this agreement was entered into immediately prior to the date of this document, it has not been possible to complete all of the formalities required to register the transfers of the shares of each relevant company in each jurisdiction prior to publication of this document. Therefore, at the date of this document, the Company is only the beneficial, and not the legal owner, of the shares in each of the following companies in the Group: Blease Medical Holdings Ltd., Spacelabs Healthcare Solutions Pvt Ltd., Spacelabs (Singapore) Pte. Ltd., Spacelabs Medical (Canada), Inc., Spacelabs Medical Finland Oy, Spacelabs Medical Germany GmbH, Spacelabs Medical SAS, Spacelabs Medical UK Ltd. The Company intends to complete such registration formalities as quickly as possible but this process may be delayed due to unforseen factors. Pending completion of such formalities, OSI or UDT Sensors (as the case may be) will remain registered as the legal owner of the relevant shares. The Company intends to submit applications for exemption from tax in respect of the transfers of shares referred to above in jurisdictions where tax would normally be payable on the transfer of shares. However, there can be no guarantee that such applications will be accepted by the relevant tax authorities. In such event, tax may become payable on the value of the stock allotted to OSI and UDT Sensors as consideration for the transfer to the Company of various companies in the Group.

AND RELATED COMPANIES -------------------------------------------------------------------------------- SPACELABS MEDICAL, INC. AND RELATED COMPANIES NOTES TO COMBINED FINANCIAL STATEMENTS YEAR ENDED JUNE 30, 2005 1. BASIS OF COMBINATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES GENERAL -- On August 2, 2005, OSI Systems, Inc. ("OSI") formed Spacelabs Healthcare, Inc. ("Spacelabs Healthcare"), which is intended to be the holding company of the following OSI healthcare division subsidiaries: (a) Spacelabs Medical, Inc. (U.S.A.) and its affiliates in Austria, Canada, China, Finland, France, Germany, Italy, Singapore and the U.K (collectively, "Spacelabs Medical"); (b) Blease Medical Holdings Ltd. (U.K.) and its wholly-owned subsidiaries Blease Medical Equipment Limited and Blease Medical Service Limited (collectively, "Blease"); (c) Dolphin Medical, Inc. (U.S.A.) and its subsidiary, Dolphin Medical Products Limited (Singapore), (collectively, "Dolphin Medical"); and (d) Osteometer MediTech, Inc. ("Osteometer"). The companies listed above are currently 100% directly or indirectly owned by OSI except for Dolphin Medical, Inc. (U.S.A), which is 89% owned by OSI and 11% owned by third parties. OSI anticipates completing an initial public offering of Spacelabs Healthcare prior to December 31, 2005. Spacelabs Medical is a global manufacturer and distributor of patient monitoring and clinical information systems for use primarily in hospitals. It designs, manufactures and markets patient monitoring solutions for critical care, emergency and perioperative areas of the hospital, wired and wireless networks and connectivity solutions, ambulatory blood pressure monitors and medical data services, all aimed at providing caregivers with instant patient information. Spacelabs Medical was acquired by OSI in March 2004. Blease is a global manufacturer and distributor of anesthesia delivery systems, ventilators and vaporisers. Blease sells its products primarily to hospitals for use in operating rooms and anesthesia induction areas as well as in magnetic resonance imaging facilities. In addition, as pharmaceutical companies develop new anesthesia agents for the worldwide market, or as generic alternatives to patented anesthesia formulas become available, Blease works closely with them to support their new product introductions. As a result, Blease also sells its actual results to differ materially from its expectations. Neither the Company nor Spacelabs intends to provide updated information other than as otherwise required by applicable law. All subsequent written and oral forward looking statements attributable to the Company and Spacelabs, or persons acting on their behalf, are expressly qualified in their entirely by the cautionary statements contained in this paragraph and elsewhere in this report.

The information in this report (including Exhibits 99.1 and 99.2) is being furnished pursuant to Item 7.01 and shall not be deemed to be "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or otherwise subject to the liabilities of that section, nor shall it be deemed to be incorporated by reference in any filing under the Act or the Exchange Act. Additionally, the submission of the report on Form 8-K is not an admission of the materiality of any information in this report that is required to be disclosed solely by Regulation FD.
