("PSS"), a corporation organized and existing under the laws of the State of

Florida, pursuant to the transactions described in the Agreement and Plan of

Merger, dated as of December 14, 1997 (the "Agreement"), by and among PSS, PSS

Merger Corp. ("Merger Corp.") and GSMS. Under the terms of the Agreement,

Merger Corp. will be merged into and with GSMS (the "Merger"), and the shares of

the $.01 par value common stock of GSMS ("GSMS Common Stock") will be converted

into and exchanged for shares of the $.01 par value common stock of PSS ("PSS

Common Stock"). This Affiliate Agreement represents an agreement between the

undersigned and PSS regarding certain rights and obligations of the undersigned

in connection with the shares of PSS to be received by the undersigned as a

result of the Merger.

In consideration of the Merger and the mutual covenants contained herein,

the undersigned and PSS hereby agree as follows:

1. Affiliate Status. The undersigned understands and agrees that as to

GSMS he is an "affiliate" under Rule 145(c) as defined in Rule 405 of the Rules

and Regulations of the Securities and Exchange Commission ("SEC") under the

Securities Act of 1933, as amended ("1933 Act"), and the undersigned anticipates

that he will be such an "affiliate" at the time of the Merger.

2. Initial Restriction on Disposition. The undersigned agrees that he

----------------------------------

will not sell, transfer, or otherwise dispose of his interests in, or reduce his

risk relative to, any of the shares of PSS Common Stock into which his shares of

GSMS Common Stock are converted upon consummation of the Merger until such time

as PSS notifies the undersigned that the requirements of SEC Accounting Series

Release Nos. 130 and 135 ("ASR 130 and 135") have been met. The undersigned

understands that ASR 130 and 135 relate to publication of financial results of

post-Merger combined operations of PSS and GSMS. PSS agrees that it will publish

such results as promptly as practicable following the Merger in the sole

discretion of PSS, but in any event within 45 days after the end of the first

fiscal quarter of PSS containing the required period of post-Merger combined

operations and that it will notify the undersigned promptly following such

publication.

3. Covenants and Warranties of Undersigned. The undersigned represents,

undersigned of PSS Common Stock has not been registered under the 1933 Act

be sold by the undersigned (1) following registration under the 1933 Act, or

(2) in conformity with the volume and other requirements of Rule 145(d)

promulgated by the SEC as the same now exist or may hereafter be amended, or

(3) to the extent some other exemption from registration under the 1933 Act

might be available. The undersigned understands that PSS is under no

------------------------------------------------

obligation to file a registration statement with the SEC covering the

---------------------------------------------------------------------

disposition of the undersigned's shares of PSS Common

-----------------------------------------------------

Stock or to take any other action necessary to make compliance with an

----------------------------------------------------------------------

exemption from such registration available.

determination of shareholders entitled to vote at the Shareholders' Meeting

of GSMS held to approve the Merger.
