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.

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.

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
