                             INTRODUCTORY STATEMENT

      The following information amends and supplements our Offer to Exchange
dated December 21, 2001. Pursuant to this Supplement, we are amending and
restating the information discussed below. Except to the extent expressly set
forth, this Supplement does not alter the terms and conditions previously set
forth in the Offer to Exchange, and should be read in conjunction with the Offer
to Exchange.

WHAT IS RESTRICTED STOCK?

      Question 3 in the Offer to Exchange, and its related answer, describe the
Restricted Stock being offered to you in exchange for your eligible options.
Please refer to Question 19 and Section 13 for a discussion of withholding taxes
and material U.S. federal income tax consequences in connection with this offer.

CONDITIONS OF OFFER

      As described in Section 6 of the Offer to Exchange, the offer is subject
to certain conditions. You must be an active employee of Safeguard on the date
the offer is made and continue to be an active employee on the date it expires.
If you accept this offer with respect to any eligible option, you must exchange
all eligible options. However, you are not required to exchange any of your
eligible options.

      Notwithstanding any other provision of the Offer to Exchange, we will not
be required to accept any eligible options that you tender for exchange, and we
may terminate or amend the offer, or postpone our acceptance and cancellation of
any eligible options that you elect to exchange, in each case at any time on or
before 12:00 midnight, Eastern Standard Time, on January 22, 2002 (or such later
date if we extend the Offer to Exchange), if we determine that any event has
occurred that, in our reasonable judgment, makes it inadvisable for us to
proceed with the Offer to Exchange or to accept and cancel eligible options that
you tender for exchange, including, but not limited to, the following:

      -     any action proceeding by any government agency, authority or
            tribunal or any other person, domestic or foreign, is threatened or
            pending before any court, authority, agency or tribunal that
            directly or indirectly challenges the making of the Offer to
            Exchange, the acquisition of some or all of the eligible options,
            the issuance of Restricted Stock, or otherwise relates to the Offer
            to Exchange or that, in our reasonable judgment, could materially
            and adversely affect our business, condition (financial or
            otherwise), income, operations or prospects or materially impair the
            benefits we believe we will receive from the Offer to Exchange;

      -     any action is threatened, pending or taken, or any approval is
            withheld, by any court or any authority, agency, tribunal or any
            person that, in our reasonable judgment, would or might directly or
            indirectly:

            (a)   make it illegal for us to accept some or all of the eligible
                  options or to issue some or all of the Restricted Stock or
                  otherwise restrict or prohibit consummation of the Offer to
                  Exchange or otherwise relate to the Offer to Exchange;

            (b)   delay or restrict our ability, or render us unable, to accept
                  the eligible options for exchange and cancellation or to issue
                  Restricted Stock for some or all of the exchanged eligible
                  options;

            (c)   materially impair the benefits we believe we will receive from
                  the Offer to Exchange; or

            (d)   (materially and adversely affect our business, condition
                  (financial or other), income, operations, or prospects;

      -     any change or changes occur in our business, condition (financial or
            other), assets, income, operations, prospects or stock ownership
            that, in our reasonable judgment, is or may be material to us. The
            conditions to the Offer to Exchange are for our benefit. We may
            assert them in our discretion before the expiration date and we may
            waive them at any time before the expiration date, whether or not we
            waive any other condition to the Offer to Exchange. Should we decide
            to waive any of the conditions to the Offer to Exchange, we must do
            so before 12:00 midnight, Eastern Standard Time, on January 22, 2002
            (or by a later expiration date if the Offer to Exchange is
            extended). Our failure to exercise any of these rights is not a
            waiver of any of these rights. The waiver of any particular right is
            not, and shall not be construed as, the waiver of any other right.
            However, once we choose to waive a particular right, we may not
            reassert that particular right again in this Offer to Exchange. Any
            determination we make concerning the events as described above will
            be final and binding on everyone.
