                  This Amendment No. 6 amends and supplements the Schedule 13D
initially filed by the Reporting Persons on June 11, 1998. It is being filed to
report an increase in beneficial ownership of the common stock of Power-One,
Inc. ("Power-One") owned by Stephens Group, Inc. Except as set forth below,
there are no changes in the Schedule 13D. Capitalized terms not otherwise
defined herein shall have the same meanings as defined in the Schedule 13D.

ITEM 2. IDENTITY AND BACKGROUND

                  Item 2 is hereby amended and supplemented by adding thereto
the following:

                  (c)(xii) In September 2002, the NASD accepted an offer of
settlement in which Stephens Inc. consented to the entry of findings that in
2000 and 2001 it did not adequately comply with MSRB Rules G-12 and G-14
regarding the reporting of municipal securities trades to the National
Securities Clearing Corporation. Stephens made changes to its systems and
procedures to correct the problem and paid a $1,500 administrative penalty.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER

                  Item 5 is hereby amended by deleting the previous Item 5 and
replacing it in its entirety with the following:

                  (a) The table below discloses the ownership of the common
stock of Power-One by the Reporting Persons and their respective directors and
executive officers.
