If the ValueAct Designee is appointed to the Board pursuant to this Section 1(a), the Company shall include the ValueAct Designee as a Class I Director, which term expires at the Company's 2016 annual meeting of stockholders.

(e) So long as the ValueAct Group collectively beneficially owns, in the aggregate, at least 7.5% of the outstanding Common Stock, if, during the Covered Period, a vacancy on the Board is created as a result of the ValueAct Designee's death, resignation, disqualification or removal, then the ValueAct Group and the Company (acting through the Board) shall work together in good faith to fill such vacancy or replace such nominee with an individual who (A) meets the Conditions, (B) meets the historical standards and criteria applied by the Company in nominating and appointing directors, and (C) is otherwise mutually acceptable (in each of their sole discretion) to the ValueAct Group and the Company, and thereafter such individual shall serve and/or be nominated as the ValueAct Designee under this Agreement.

(f) The Company's obligations hereunder shall terminate immediately, and the ValueAct Designee shall promptly offer to resign from the Board, and any committee of the Board on which he then sits (and, if requested by the Company, promptly deliver his written resignation to the Board (which shall provide for his immediate resignation) it being understood that it shall be in the Board's sole discretion whether to accept or reject such resignation) if: (i) members of the ValueAct Group, collectively, cease to beneficially own at least 7.5% of the Company's outstanding Common Stock; (ii) the ValueAct Designee ceases to satisfy the conditions set forth in clauses (c)-(d) above; (iii) a member of the ValueAct Group, including the ValueAct Designee, otherwise ceases to comply or breaches any of the terms of this Agreement or the Confidentiality Agreement; or (iv) the employment of the ValueAct Designee with the ValueAct Group is terminated for any reason. The ValueAct Group agrees to cause the ValueAct Designee to resign from the Board if the ValueAct Designee fails to resign if and when requested pursuant to this Section 1(f). Notwithstanding the foregoing, in the event of the occurrence of an event set forth in subsection (ii) or (iv) above, the provisions of Section 1(e) must be complied with before the Company's obligations hereunder may terminate.

(g) The percentage thresholds set forth in clauses (e) and (f) above shall not be deemed unsatisfied to the extent a failure to maintain the specified ownership thresholds is the result of share issuances or similar Company actions that increase the number of outstanding shares of Common Stock.

This requirement is    satisfied if, taking into account those GSMS shareholders who receive cash in    exchange for their stock, who receive cash in lieu of fractional shares, or    who dissent from the Merger, there is no plan or intention on the part of the    GSMS shareholders to sell or otherwise dispose of the PSS Common Stock to be    received in the Merger that will reduce such shareholders' ownership to a    number of shares having, in the aggregate, a value at the time of the Merger    of less than 50% of the total fair market value of the GSMS Common Stock    outstanding immediately prior to the Merger. The undersigned has no    prearrangement, plan or intention to sell or otherwise dispose of an amount    of his PSS Common Stock to be received in the Merger which would cause the    foregoing requirement not to be satisfied.

     4.  Restrictions on Transfer.  The undersigned understands and agrees that          ------------------------                                               stop transfer instructions with respect to the shares of PSS Common Stock received by the undersigned pursuant to the Merger will be given to PSS's transfer agent and that there will be placed on the certificates for such shares, or shares issued in substitution thereof, a legend stating in substance:

   The shares represented by this certificate were issued pursuant to a    business combination which is accounted for as a pooling of interests and    may not be sold, nor may the owner thereof reduce his risks relative thereto    in any way, until such time as PSS, Inc. (PSS) has published the financial    results covering at least 30 days of combined operations after the effective    date of the merger through which the business combination was effected.  In    addition, the shares represented by this certificate may not be sold,    transferred or otherwise disposed of except or unless (1) covered by an    effective registration statement under the Securities Act of 1933, as    amended, (2) in accordance with (i) Rule 145(d) (in the case of shares issued    to an individual who is not an affiliate of PSS) or (ii) Rule 144 (in the                            ---                                                  case of shares issued to an individual who is an affiliate of PSS) of the    Rules and Regulations of such Act, or (3) in accordance with a legal opinion    satisfactory to counsel for PSS that such sale or transfer is otherwise    exempt from the registration requirements of such Act.

Such legend will also be placed on any certificate representing PSS securities issued subsequent to the original issuance of the PSS Common Stock pursuant to the Merger as a result of any transfer of such shares or any stock dividend, stock split, or other recapitalization as long as the PSS Common Stock issued to the undersigned pursuant to the Merger has not been transferred in such manner to justify the removal of the legend therefrom.  Upon the request of the undersigned, PSS shall cause the certificates representing the shares of PSS Common Stock issued to the undersigned in connection with the Merger to be reissued free of any legend relating to restrictions on transfer by virtue of ASR 130 and 135 as soon as practicable after the requirements of ASR 130 and 135 have been met.  In addition, if the provisions of Rules 144 and 145 are amended to eliminate restrictions applicable to the PSS Common Stock received by the undersigned pursuant to the Merger, or at the expiration of the restrictive period set forth in Rule 145(d), PSS, upon the request of the undersigned, will cause the certificates representing the shares of PSS Common Stock issued to the undersigned in connection with the Merger to be reissued free of any legend relating to the restrictions set forth in Rules 144 and 145(d) upon receipt by PSS of an opinion of its counsel to the effect that such legend may be removed.

                                     - 2 -

       5.  Understanding of Restrictions on Dispositions.  The undersigned has          ---------------------------------------------                       carefully read the Agreement and this Affiliate Agreement and discussed their requirements and impact upon his ability to sell, transfer, or otherwise dispose of the shares of PSS Common Stock received by the undersigned, to the extent he believes necessary, with his counsel or counsel for GSMS.

     6.  Filing of Reports by PSS.  PSS agrees, for a period of three years          ------------------------                                           after the effective date of the Merger, to file on a timely basis all reports required to be filed by it pursuant to Section 13 of the Securities Exchange Act of 1934, as amended, so that the public information provisions of Rule 145(d) promulgated by the SEC as the same are presently in effect will be available to the undersigned in the event the undersigned desires to transfer any shares of PSS Common Stock issued to the undersigned pursuant to the Merger.

     7.  Transfer Under Rule 145(d).  If the undersigned desires to sell or          --------------------------                                         otherwise transfer the shares of PSS Common Stock received by him in connection with the Merger at any time during the restrictive period set forth in Rule 145(d), the undersigned will provide the necessary representation letter to the transfer agent for PSS Common Stock together with such additional information as the transfer agent may reasonably request.  If PSS's counsel concludes that such proposed sale or transfer complies with the requirements of Rule 145(d), PSS shall cause such counsel to provide such opinions as may be necessary to PSS's Transfer Agent so that the undersigned may complete the proposed sale or transfer.

     8.  Acknowledgments.  The undersigned recognizes and agrees that the          ---------------                                                  foregoing provisions also apply to all shares of the capital stock of GSMS and PSS that are deemed to be beneficially owned by the undersigned pursuant to applicable federal securities laws, which the undersigned agrees may include,





without limitation, shares owned or held in the name of (i) the undersigned's spouse, (ii) any relative of the undersigned or of the undersigned's spouse who has the same home as the undersigned, (iii) any trust or estate in which the undersigned, the undersigned's spouse, and any such relative collectively own at least a 10% beneficial interest or of which any of the foregoing serves as trustee, executor, or in any similar capacity, and (iv) any corporation or other organization in which the undersigned, the undersigned's spouse and any such relative collectively own at least 10% of any class of equity securities or of the equity interest.  The undersigned further recognizes that, in the event that the undersigned is a director or officer of PSS or becomes a director or officer of PSS upon consummation of the Merger, among other things, any sale of PSS Common Stock by the undersigned within a period of less than six months following the effective time of the Merger may subject the undersigned to liability pursuant to Section 16(b) of the Securities Exchange Act of 1934, as amended.

     9.  Miscellaneous.  This Affiliate Agreement is the complete agreement          -------------                                                      between PSS and the undersigned concerning the subject matter hereof.  Any notice required to be sent to any party hereunder shall be sent by registered or certified mail, return receipt requested, using the addresses set forth herein or such other address as shall be furnished in writing by the parties.  This Affiliate Agreement shall be governed by the laws of the State of Delaware.
