No. 2 is filed on behalf of Wave.

    This Amendment No. 2 is being filed to describe the plan that Wave has of

set forth in such Rule, or pursuant to one or more private sales.  Wave plans to
dispose of these securities in order to raise capital.

     Wave does not have any plans or proposals that relate to or would result
in: (i) any extraordinary corporate transaction; (ii) any sale or transfer of a
material amount of assets of SSP or any of its subsidiaries; (iii) any change in
the present board of directors or management of SSP; (iv) any material change in
the present capitalization or dividend policy of SSP; (v) any other material
change in SSP's business or corporate structure; (vi) any changes in SSP's
charter, bylaws or instruments corresponding thereto, or other actions which may
impede the acquisition of control of SSP by any person; (vii) causing a class of
securities of SSP to be delisted from a national securities exchange or to cease
to be authorized to be quoted in an inter-dealer quotation system of a
registered national securities association; (viii) a class of equity securities
of SSP becoming eligible for termination of registration pursuant to Section
12(g)(4) of the Securities Exchange Act of 1934; or (ix) any action similar to
any of those enumerated above.

Item 5.  Interest in Securities of the Issuer.

     Items 5(a), 5(b) and 5(c) are amended to read as follows:

     (a)  Wave owns 4,788,083 shares of common stock of SSP, which equal
approximately 19.1007% of the total 25,067,576 outstanding shares of common
stock of SSP as of April 8, 2003.

     (b)  Wave has sole voting and dispositive power to all 4,788,083 shares
that it owns.

     (c)  On April 7, 2003, Wave sold 20,000 shares of SSP's common stock on the
open market for $0.55.  On April 8, 2003, Wave sold an additional 75,000 shares
