Item 4 is amended to include the following:

      Safeguard Delaware, Inc. ("SDI"), Safeguard Scientifics (Delaware), Inc.
("SSDI") and the Company are parties to a Registration Rights Agreement dated as
of July 17, 1997, that entitles SDI and SSDI, under certain circumstances, to
require the Company to register for resale certain shares of the Company's Class
A Common Stock held by each of SDI and SSDI. SDI and SSDI recently exercised
their registration rights under that agreement, and the Company included in its
Registration Statement on Form S-3 filed with the Securities and Exchange
Commission on March 28, 2005 (the "Registration Statement"), an aggregate of
5,276,836 shares of Class A Common Stock, of which 1,122,915 shares are owned by
SDI and 4,153,921 shares are owned by SSDI (the "Shares"). The inclusion of the
Shares in the Registration Statement will facilitate a potential disposition of
the Shares by SDI and SSDI.

      Except as set forth in this item, the Reporting Persons have not
formulated any plans or proposals of the types referred to in clauses (a)
through (j) of Item 4 of Schedule 13D (although each Reporting Person reserves
the right to develop such plans).

has consummated any transaction in the Company's shares during the past 60 days.
