(formerly QIC Holding Corp.), a California corporation ("Quinton"). The principal executive office of Quinton is located at 3303 Monte Villa Parkway, Bothell, Washington 98021. ITEM 2. IDENTITY AND BACKGROUND (a) This statement is being filed by Koninklijke Philips Electronics N.V.("KPENV"), Philips Holding USA Inc.

Hambrecht/QIC Management, LLC, a California limited liability company ("WRH Management"), and PENAC, attached hereto as Exhibit 1 and incorporated herein by reference, the Reporting Persons believe that they, WRH and certain individuals and entities related to WRH (the "WRH Group") may be deemed to constitute a "group" for purposes of Section 13(d)(3) of the Securities Exchange Act of 1934 and Rule 13d-5(b)(1) promulgated thereunder.

Based upon the WRH Group Reports and the Registration Statement, the Reporting Persons believe that WRH is the direct beneficial owner of 5,056,215 Shares. The Reporting Persons disclaim beneficial ownership of the Shares held by WRH, and this statement shall not be construed as an admission that any of the Reporting Persons is, for the purposes of Section 13(d) or 13(g) CUSIP Number: 748773 10 8 Page 6 of 25 of the Securities Exchange Act of 1934 or for any other purpose, the beneficial owner of the Shares held by WRH.

Zymed disclaims beneficial ownership of the Shares held by WRH, and this statement shall not be construed as an admission that Zymed is, for the purposes of Section 13(d) or 13(g) of the Securities Exchange Act of 1934 or for any other purpose, the beneficial owner of the Shares held by WRH. Certain information concerning each director and executive officer of (i) PENAC is set forth in Schedule I hereto and incorporated herein by reference and (ii) KPENV is set forth in Schedule II hereto and incorporated herein by reference. (b) The principal business address of KPENV is Breitner Center, Amstelplein 2, 1096 BC Amsterdam, The Netherlands. The principal business address of PHUSA and PENAC is 1251 Avenue of the Americas, New York, New York 10020. (c) The primary business of each of the Reporting Persons is the manufacture and distribution of electronic and electrical products, systems and equipment, as well as information technology services. (d) None of the Reporting Persons, or to the best knowledge and belief of the Reporting Persons, any of the individuals listed on Schedule I or II has, during the past five years, been convicted in any criminal proceeding (excluding traffic violations or similar misdemeanors). (e) None of the Reporting Persons, or to the best knowledge and belief of the Reporting Persons, any of the individuals listed on Schedule I or II has, during the past five years, been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws. CUSIP Number: 748773 10 8 Page 7 of 25 (f) KPENV is a company incorporated under the laws of the Netherlands. PHUSA and PENAC are Delaware corporations. This Item 2 is qualified in its entirety by reference to Schedules I and II which are incorporated herein by reference. ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION Pursuant to the Asset Purchase Agreement, dated as of November 17, 2000, between Agilent Technologies, Inc., a Delaware corporation ("Agilent"), and KPENV, and the Amendment and Supplemental Agreement, dated as of August 1, 2001, between Agilent and KPENV, on August 1, 2001, PENAC acquired 19 shares of Class A Common Stock and 2,330,000 shares of Series A Preferred Stock of Quinton for $4,000,000, the source of which funds was working capital. Each share of Series A Preferred Stock was convertible into one share of Class A Common Stock at the option of the holder, subject to certain adjustments. Pursuant to Article III(d)(3)(ff) of the Certificate of Amendment of Articles of Incorporation of Quinton, dated June 2, 1998 (the "Certificate of Amendment"), the holders of Series A Preferred Stock were entitled to receive certificates of adjustment regarding certain anti-dilution adjustments upon the grant of certain shares of Class A Common Stock or certain options to purchase shares of Class A Common Stock under Quinton's 1998 Equity Incentive Plan. In place of these certificates of adjustment PENAC was granted 287,977 additional, uncertificated shares of Series A Preferred Stock, recorded on the books of Quinton as of August 1, 2001. On April 5, 2002, pursuant to a 2.2-for-1 stock split and a redesignation of the Class A Common Stock into Shares, the 19 shares of Class A Common Stock held by PENAC were redesignated into 8 Shares. Assuming a 2.2-for-1 stock split and conversion of the Series A Preferred Stock into Shares at the closing of the initial public offering referred to in the Registration Statement, the 2,617,977 shares of Series A Preferred Stock held by PENAC will be converted into 1,189,989 Shares. The Reporting Persons have not purchased or sold any securities of Quinton in the last 60 days. CUSIP Number: 748773 10 8 Page 8 of 25 None of the persons listed on Schedule I or II hereto has contributed any funds or other consideration towards the purchase of the shares of Quinton reported in this statement. Information about the WRH Group is disclosed in the Registration Statement and the WRH Group Reports. ITEM 4. PURPOSE OF TRANSACTION 1,059,098 Shares were acquired by the Reporting Persons in connection with the Agilent Transaction and 130,899 shares were acquired as a result of anti-diluation adjustments. Pursuant to a Letter Agreement, dated February 19, 2002 (the "Letter Agreement"), by and among PENAC, KPENV and Agilent, attached hereto as Exhibit 2 and incorporated herein by reference, PENAC is a successor in interest to Hewlett-Packard Company, a Delaware corporation ("HP"), in an Investors' Rights Agreement, dated as of May 27, 1998 (the "Investors' Rights Agreement"), between Quinton, WRH and HP (the "Investors' Rights Agreement"), attached hereto as Exhibit 3 and incorporated herein by reference. Pursuant to the Investors' Rights Agreement, subject to certain conditions and limitations set forth therein, WRH and PENAC may require Quinton to use its best efforts to include their Shares in any registration by Quinton of its Shares at Quinton's expense. These registration rights are subject to conditions and limitations including that, if the registration is in connection with an underwritten public offering, the holder is obligated to participate in the underwriting and the underwriters have the right to exclude all or limit the number of the holder's shares included in the registration statement. The Investors' Rights Agreement also imposes certain restrictions on the transfer of shares held by WRH and PENAC, and by any successors in interest to them, including requiring any transferee to agree to be bound by the transfer restrictions in the Investors' Rights Agreement and requiring either that an effective registration statement cover the disposition or that Quinton be notified of the disposition by the transferor and that the transfer not require registration. Pursuant to the Shareholders Agreement, WRH has the right to designate up to three nominees to the board of directors of Quinton and WRH and PENAC (the "Holders") are required to vote their shares in Quinton in favor of those nominees. PENAC and CUSIP Number: 748773 10 8 Page 9 of 25 Zymed each have the right to designate one nominee to Quinton's board of directors and the Holders are required to vote their shares in Quinton in favor of those nominees. Neither PENAC nor Zymed has exercised its right to designate a nominee for election to Quinton's board or indicated whether it intends in the future to designate a nominee to the board. The Shareholders Agreement also states that the board of directors of Quinton shall consist of five members and prohibits an increase in the number of directors of Quinton above seven without the consent of PENAC. In addition, if WRH or any of its members transfers control of Quinton or WRH to any transferee that will own more than 50% of Quinton's outstanding voting stock or more than 50% of the membership units of WRH, PENAC has the right to sell the shares in Quinton that it holds on the same terms to such transferee. Shares held by WRH and PENAC cannot be encumbered as security for debt, and transferees of shares owned by WRH or PENAC must agree to be bound by the Shareholders Agreement as a condition to transfer. The Shareholders Agreement also provides that the unanimous written consent of Quinton's board of directors is required with respect to the payment of compensation to any of Quinton's employees, consultants or board members who is an employee, consultant, director or manager of WRH or WRH LLC or any entity controlled by either of them or which controls either of them, or an employee, consultant or director of PENAC or Zymed unless such individual is one of Quinton's full time employees. The Shareholders Agreement can only be terminated with the consent of the parties thereto. In March, 1999, Quinton, Inc. ("QIC"), a Washington corporation and a wholly owned subsidiary of Quinton, formerly known as Quinton Instrument Company, Quinton signed an Original Equipment Manufacturer and Distributor Agreement (the "OEM Agreement") with Zymed, effective as of July 1998, providing for the purchase of certain Holter monitoring items, and appointed QIC the exclusive distributor of such products in the United States and Canada for a period of five years. The OEM Agreement is attached hereto as Exhibit 4 and incorporated herein by reference. According to the Registration Statement, the products supplied under this agreement represented a significant portion of Quinton's revenues, approximately 8% in 1999, 12% in 2000 and 3% in 2001. In the third quarter of 2000, Zymed terminated the OEM Agreement because the parties failed to agree on pricing and volume requirements as set forth in the OEM Agreement. This notice of termination provided for a 180 day notice period that expired in February 2001. QIC disputed this notice of termination and in CUSIP Number: 748773 10 8 Page 10 of 25 November 2000 initiated a lawsuit in the United States District court for the Western District of Washington against Zymed, Agilent and HP, seeking damages against the defendants for harm to its business resulting from Zymed's termination of the OEM Agreement. QIC is seeking monetary damages and other remedies available under the law. On April 8, 2002, the court entered an order dismissing all of QIC's claims other than the claims related to breach of contract. The trial date, originally scheduled for late April 2002, has been set for September 18, 2002. The Reporting Persons believe that the claims QIC has made in connection with the lawsuit are wholly without merit, and they are cooperating in a vigorous defense of such claims. Regardless of the underlying merit of such claims, however, the Reporting Persons and/or their respective subsidiaries may from time to time engage in mediation, arbitration and/or negotiations with Quinton and QIC with a view to resolving such claims. Any such mediation, arbitration and/or negotiations may or may not include discussions concerning -- and any resolution of such claims may or may not include -- the acquisition or disposition by the Reporting Persons of Shares or other securities of Quinton, the sale or transfer of cash or other assets of Quinton and/or its subsidiaries, the amendment, modification and/or termination of the Investors Rights Agreement and/or the Shareholders Agreement, and/or extraordinary corporate transactions. None of the Reporting Persons, Quinton or QIC is under any obligation to agree to any resolution or settlement of the litigation. Information about the WRH Group is disclosed in the Registration Statement the WRH Group Reports. The foregoing discussion is qualified in its entirety by reference to the Letter Agreement, the Investors' Rights Agreement, the Shareholders Agreement and the OEM Agreement. Other than as set forth herein, none of the Reporting Persons, or to the best knowledge and belief of the Reporting Persons, any of the individuals listed on Schedule I or II, has plans or proposals which relate to or would result in any of the events described by Items 4(a) through 4(j) of Schedule 13D. Each Reporting Person expects to evaluate on an ongoing basis Quinton's financial condition, business operations and prospects, market price of the Shares of Quinton, conditions in securities markets generally, general economic and industry conditions and CUSIP Number: 748773 10 8 Page 11 of 25 other factors. Accordingly, each Reporting Person reserves the right to change its plans and intentions at any time, as it deems appropriate. In particular, each Reporting Person may at any time and from time to time acquire additional Shares of Quinton or securities convertible or exchangeable for Shares of Quinton; may dispose of Shares of Quinton; and/or may enter into privately negotiated derivative transactions with institutional counterparties to hedge the market risk of some or all of its positions in such Shares. Any such transactions may be effected at any time and from time to time subject to any applicable limitations of the Securities Act and the contractual restrictions described herein. To the knowledge of each Reporting Person, each of the persons listed on Schedules I and II hereto may make the same evaluation and reserves the same rights. ITEM 5.

ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER There are no contracts, arrangements, understandings or relationships between the Reporting Persons (or their wholly owned subsidiaries), and to the best knowledge and belief of the Reporting Persons, none of the persons listed on Schedules I and II hereto, and other persons with respect to the Shares of Quinton aside from: Pursuant to the Letter Agreement, PENAC is a successor in interest to HP in an Investors' Rights Agreement. Pursuant to the Investors' Rights Agreement, and subject to conditions and limitations, WRH and PENAC may require Quinton to use its best efforts to include their Shares in any registration by Quinton of its Shares at Quinton's expense. These registration rights are subject to conditions and limitations including, if the registration is in connection with an underwritten public offering, the holder's obligation to participate in the underwriting and the right of the underwriters to exclude all or limit the number of shares included in the registration statement. The Investors' Rights Agreement also imposes restrictions on the transfer of shares held by WRH and PENAC, and by any successors in interest to them, including requiring any transferee to agree to be bound by Section 2 of the Investors' Rights Agreement (which section contains the restrictions on transfer) and requiring either that an effective registration statement cover the disposition or that Quinton be notified of the disposition by the transferor and that the transfer not require registration. PENAC is party to the Shareholders Agreement which provides that WRH has the right to designate up to three nominees to the board of directors of Quinton and PENAC is required to vote its shares in Quinton in favor of those nominees.
