ITEM 1. SECURITY AND ISSUER. This statement relates to the Common Stock of the Company. The address of the principal executive offices of the Company is: 9 Parker Irvine, California 92618-1605 ITEM 2. IDENTITY AND BACKGROUND. This statement is being filed by Owner, Baxter Healthcare Corporation, a Delaware corporation and the owner of 100% of the membership interests of Owner ("BHC") and Baxter International Inc., a Delaware corporation and the owner of 100% of the capital stock of BHC ("Parent"). The principal executive offices of Owner, BHC and Parent are: One Baxter Parkway Deerfield, Illinois 60015 Telephone: 847.948.2000 Parent, BHC and Owner, through its subsidiaries, are engaged in the worldwide development, distribution and manufacture of a diversified line of products, systems and services used primarily in the health care field. Neither Parent, BHC nor Owner, nor, to the best of the knowledge of Parent, BHC and Owner, any director or executive officer of Parent, BHC or Owner, has been, during the last five years, (a) convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (b) 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.

As described in Item 4 below, in consideration of the BHC's tender of common stock, warrants and debentures of Issuer's subsidiary to the Issuer, BHC received from Issuer 750,000 shares of Page 3 of 10 Pages CUSIP No. 65332H104 (Previous CUSIP No.: 927186106) -------------------------------------------------------------------------------- Common Stock, a warrant to purchase 1,300,000 shares of Common Stock, and certain debentures of the Issuer. As described in Item 4 below, BHC received 63,000 shares of Series B Preferred Stock of The Issuer from four institutional investors and their affiliates in exchange for $72,658,868.57, which funds were obtained from internally generated funds. As described in Item 4 below, upon conversion of 1,321 shares of Series B Preferred Stock of the Issuer, BHC received 14,677,631 shares of Common Stock of the Issuer. ITEM 4. PURPOSE OF TRANSACTION. Prior to June 30, 1999, the Company owned 80.5% of Nexell of California, Inc. (formerly known as Nexell Therapeutics Inc.) ("Sub"), the Company's principal business unit, which it acquired through the acquisition of certain assets from BHC in December 1997 in exchange for (1) 2,500,000 shares of Common Stock, (2) 66,304 shares of Series A Convertible Preferred Stock of the Company with a liquidation value of $1,000 per share ("Series A Preferred Stock"), (3) 19.5 % of Sub's outstanding common stock, (4) a warrant to purchase an additional 6% of Sub's common stock for $6,000,000, and (5) the right of BHC to receive payments from Sub upon the occurrence of certain milestone events, which could aggregate $21,000,000 if all the milestones were achieved. In addition, for $30,000,000 paid to Sub, BHC received $30,000,000 principal amount of Sub's 6 1/2% convertible subordinated debentures convertible into Sub's common stock upon a public offering of common stock by Sub. The acquisition by the Company of BHC's interests in Sub, other than its right to milestone payments, was effected through an exchange of BHC's interests in Sub for an equivalent value of interests directly in the Company (the "Acquisition"). The Company and BHC agreed to exchange BHC's interests in Sub (common stock, warrant and convertible subordinated debentures, but excluding its right to milestone payments) for: .. 750,000 shares of Common Stock; .. an adjustment of the conversion price of the shares of Series A Preferred Stock owned by BHC to $11.00 per share; .. a warrant to purchase 1,300,000 shares of Common Stock at a price of $4.60 per share (the "Warrant"); and .. $32,884,537.50 principal amount of 6 1/2% Convertible Subordinated Debentures convertible, commencing November 30, 2002, into Common Stock at a conversion price equal to 95% of the average of the closing prices of the Common Stock on the Nasdaq National Market for the 30 consecutive trading days preceding the date of conversion. On May 28, 1999, December 17, 1999, December 17, 2000 and December 17, 2001, pursuant to the terms of the Series A Preferred Stock owned by BHC, the Company, respectively, issued 3,978, 4,216, 4,469 and 4,738 additional shares of Series A Preferred Stock to BHC as a result of dividends payable in kind. Page 4 of 10 Pages CUSIP No. 65332H104 (Previous CUSIP No.: 927186106) -------------------------------------------------------------------------------- As contemplated by the Process Agreement described in Item 6, on October 23, 2002 BHC acquired 63,000 shares of Series B Preferred Stock together with the Class A Warrant and Class B Warrant described in Item 5 from four institutional investors and their affiliates for a purchase price of $72,658,868.57. On October 31, 2002 BHC put the Series B Preferred Stock to Parent and Parent transferred such Preferred Stock to BHC. On November 1, 2002 BHC converted 1,321 shares of the Series B Preferred Stock into 14,677,631 shares of Common Stock of the Issuer. Subsequently, BHC transferred all of its interests in Common Stock, Series A Preferred Stock, Series B Preferred Stock and warrants to purchase Common Stock of the Issuer to Owner. Other than as described herein in Items 4 and 6, neither Owner, BHC nor Parent presently has any plans or proposals which relate to, or may result in, any of the matters listed in Items 4(a) - 4(j) of Schedule 13D, although each reserves the right to develop such plans. ITEM 5. INTEREST IN SECURITIES OF THE ISSUER. Except as set forth herein, neither Owner, BHC, Parent, nor, to the best of the knowledge of Owner, BHC and Parent, any director or executive officer of Owner, BHC or Parent beneficially owns any other shares of Common Stock of the Company. (a) Owner, BHC and Parent beneficially own an aggregate of 18,177,631 shares of Common Stock, which constitute approximately 51% of the total number of presently outstanding shares of Common Stock. Owner, BHC and Parent also each beneficially own the right to acquire up to 1,300,000 more shares of Common Stock pursuant to the Warrant. In addition, Owner, BHC and Parent each beneficially own 83,705 shares of Series A Preferred Stock presently convertible into 7,609,545 shares of Common Stock, and 61,679 shares of Series B Preferred Stock presently convertible into 685,315,369 shares of Common Stock. Owner, BHC and Parent also each beneficially own the right to acquire up to 808,686 shares of Common Stock pursuant to the Class B Warrant. The Class A Warrant will not become exercisable until November 24, 2004. The number of shares of Common Stock into which the Class A Warrant is exercisable will be between 0 and 1,500,000, depending on the market price of Common Stock on November 24, 2004. Assuming the exercise of the Warrant and the Class B Warrant and the conversion of the shares of Series A and Series B Preferred Stock, Owner, BHC and Parent would each beneficially own 713,211,232 shares of Common Stock, which would constitute approximately 97% of the outstanding shares of Common Stock. (b) Owner, BHC and Parent share the power to vote and dispose of the Shares. (c) Not applicable. (d) Not applicable. (e) Not applicable. Page 5 of 10 Pages CUSIP No. 65332H104 (Previous CUSIP No.: 927186106) -------------------------------------------------------------------------------- ITEM 6. CONTRACTS OR ARRANGEMENTS WITH RESPECT TO ISSUER SECURITIES. In addition to the agreement documenting the Acquisition described in Item 4 above, BHC has entered into the following contracts or arrangements with the Company and others with respect to the Company's securities: The Series A Preferred Stock Owner holds 83,705 shares of Series A Preferred Stock, which are presently convertible at the option of Owner. The shares will automatically convert into Common Stock on December 17, 2004 or upon other specified events, if not otherwise already converted. The conversion price at which shares of Common Stock will be deliverable upon conversion without the payment of additional consideration by Owner is $11.00 per share, subject to adjustment for stock splits and combinations, certain dividends and distributions, and reclassification, exchange or substitution. There is a 6% dividend payable annually in kind on the shares of Series A Preferred Stock. Accordingly, if Owner does not convert any shares prior to December 17, 2004, on such date it would own 99,693 shares of Series A Preferred Stock as a result of the additional shares of Series A Preferred Stock issued in payment of the 6% annual dividend; such 99,693 shares would automatically convert into 9,063,000 shares of Common Stock on such date. The Warrant The Warrant entitles Owner to purchase up to 1,300,000 shares of Common Stock at any time prior to May 27, 2006 at 5:00 p.m. at a purchase price of $4.60 per share, subject to adjustment from time to time in the event of cash dividends, stock dividends, stock subdivisions, stock splits, stock combinations or reverse stock splits. Pursuant to the Process Agreement described below, BHC and Parent have agreed not to exercise the Warrant unless the Plan of Complete Liquidation and Dissolution of the Company is not carried out as contemplated by the Process Agreement. Registration Rights Agreement Owner and the Company are parties to a Registration Rights Agreement whereby the Company has granted certain demand and piggyback rights to Owner. Voting Agreement BHC is a party to a Voting Agreement with certain other stockholders of the Company pursuant to which all parties agree to vote all of their Common Stock of the Company in favor of one BHC-nominated director. In addition, BHC agrees to vote all of its Common Stock of the Company in favor of the nominees for director recommended by the Company's nominating committee. Relationship Restructuring On November 24, 1999, BHC and the Company entered into a Put Agreement whereby BHC agreed to issue Put Rights in connection with the private placement by the Company of $63,000,000 aggregate principal amount of Series B Preferred Stock, warrants to purchase common stock of Company, and Put Rights. Each Put Right entitles the holder to cause Parent to Page 6 of 10 Pages CUSIP No. 65332H104 (Previous CUSIP No.: 927186106) -------------------------------------------------------------------------------- purchase the shares of Series B Preferred Stock during a specified time frame at a price equal to the original purchase price of the Series B Preferred Stock plus a specified rate of return. The Put Right is exercisable by holders at any time between November 24, 2002 and November 24, 2004, unless earlier terminated as provided in the Put Certificate. In addition, Parent and the Company entered into a Side Letter whereby the conversion price of the Series B Preferred Stock is to be adjusted downward per the terms of the Side Letter in the event of a put to Parent of the Series B Preferred Stock by the holders. Process Agreement On October 16, 2002 BHC and Parent entered into a Process Agreement with the Company pursuant to which the Company's Board of Directors approved a Plan of Complete Liquidation and Dissolution and BHC and Parent agreed that, notwithstanding the liquidation preference of the holders of Series A Preferred Stock and Series B Preferred Stock in the aggregate amount of approximately $151 million, the holders of the Company's common stock (other than BHC, Parent and their affiliates) would be entitled to receive a cash distribution in an amount of $0.05 per share (but not to exceed an aggregate amount of $872,026 to all holders of our common stock). BHC and Parent also agreed to acquire all of the Company's Series B Preferred Stock, together with associated warrants, from eight institutional investors. The Series B Preferred Stock is subject to certain put rights described below granted by Parent on November 24, 1999, pursuant to which Parent is obligated to purchase such shares, at the option of the holders of such shares. BHC and Parent also agreed to cause the exercise of the put rights in full no later than immediately prior to the record date for stockholder consent to the Company's Plan of Complete Liquidation and Dissolution. In consideration of the benefits afforded to the Company and the holders of its common stock (other than BHC, Parent and their affiliates) the Company agreed to the acceleration of the exercisability of the put rights, and, that pursuant to the terms of a Side Letter Agreement dated November 24, 1999, among Parent, the Company and certain other parties, the conversion price of the Series B Preferred Stock in the hands of BHC, Parent and their affiliates following the exercise of the put rights would be adjusted to a price of $0.09 per share. BHC and Parent agreed to cause the conversion into common stock of the number of shares of the Series B Preferred Stock required for BHC, Parent and their affiliates to hold a majority of the outstanding shares of the Company's common stock, and further agreed to cause the execution of a written consent approving the Company's Plan of Complete Liquidation and Dissolution. The remaining Series B Preferred Stock and all of the Series A Preferred Stock will not be converted to common stock and will retain their liquidation preference, which will allow BHC, Parent and their affiliates to receive substantially all of the assets of the Company, other than the distribution of $0.05 per share of Company common stock and other than a contingency reserve to satisfy current and anticipated liabilities. The Process Agreement also provides that immediately after the approval of the Board of Directors of the Company of the Plan of Complete Liquidation and Dissolution and certain other matters, Victor W. Schmitt will be appointed to the Board of Directors of the Company. The Series B Preferred Stock Owner holds 61,679 shares of Series B Preferred Stock, which are presently convertible at the option of Owner. The shares will automatically convert into Common Stock on November 24, 2006, if not otherwise already converted. The conversion price at which shares of Common Stock Page 7 of 10 Pages CUSIP No. 65332H104 (Previous CUSIP No.: 927186106) -------------------------------------------------------------------------------- will be deliverable upon conversion without the payment of additional consideration by Owner is $0.09 per share, subject to adjustment for stock splits and combinations, certain dividends and distributions, and reclassification, exchange or substitution. There is a 3% dividend payable semi-annually in cash. If Owner does not convert any shares prior to November 24, 2006, on such date such shares would automatically convert into 685,315,369 shares of Common Stock. The Class A Warrant The Class A Warrant entitles Owner to purchase shares of Common Stock beginning on November 24, 2004 and ending on December 16, 2004 at a purchase price of $0.04 per share, subject to adjustment from time to time in the event of cash dividends, stock dividends, stock subdivisions, stock splits, stock combinations or reverse stock splits. The number of shares of Common Stock into which the Class A Warrant is exercisable will be between 0 and 1,500,000, depending on the market price of Common Stock on November 24, 2004. Pursuant to the Process Agreement described below, BHC and Parent have agreed not to exercise the Class A Warrant unless the Plan of Complete Liquidation and Dissolution of the Company is not carried out as contemplated by the Process Agreement. The Class B Warrant The Class B Warrant entitles Owner to purchase up to 808,686 shares of Common Stock at any time prior to December 16, 2004 at a purchase price of $11.129 per share, subject to adjustment from time to time in the event of cash dividends, stock dividends, stock subdivisions, stock splits, stock combinations or reverse stock splits. Pursuant to the Process Agreement described below, BHC and Parent have agreed not to exercise the Class B Warrant unless the Plan of Complete Liquidation and Dissolution of the Company is not carried out as contemplated by the Process Agreement. Securities Agreement The Series B Preferred Stock was issued to the original institutional investor holders thereof pursuant to a Securities Agreement, dated November 24, 1999. Under that agreement, which was assigned to BHC in connection with the acquisition by BHC of the Series B Preferred Stock, the holders of the Series B Preferred Stock are entitled to the benefit of certain covenants and consent rights relating to certain significant transactions by the Company. The rights under the Securities Agreement are currently held by Owner. Except as set forth above, to the best knowledge of Owner, BHC and Parent, no contracts, arrangements, understandings or relationships (legal or otherwise) exist among the persons named in Item 2 above, or between such persons and any other person with respect to any securities of the Company, including, but not limited to, transfer or voting of such securities, finder's fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding or proxies.
