2.                                       Restrictions Upon Transfer.  SSB, DST, and Clarke & Tilley each covenant and agree that it shall not, without the prior written consent of the others, transfer its Shares or any part of its Shares before December 31, 1995; provided, however, that any party may transfer its shares at any time to an Affiliate if such Affiliate agrees in writing to be bound by this Agreement.  For purposes of this Agreement:  an “Affiliate” of a party shall mean the parent of such party (a corporation owning 51% or more of the capital stock of such party) and any Subsidiary of such party or such party’s parent; and a “Subsidiary” shall mean a corporation, 51% of more of the capital stock of which is owned by a party or a party’s parent and which is managed and controlled by such party or parent.

3.                                       Right of First Refusal.

(a)           Restriction.  After December 31, 1995 neither SSB, DST nor Clarke & Tilley shall at any time during the term of this Agreement transfer any interest in all or any part of the Shares now owned or hereafter acquired by it without first having offered it to the others in accordance with the terms and conditions of this Agreement.

(b)           Notice.  If either SSB, DST or Clarke & Tilley desires to transfer (the “Transferring Party”), all or part of its Shares it shall first receive an unconditional bona fide written offer from a third party to purchase such Shares and shall give written notice to the others (the “Non-Transferring Parties”) and to the Corporation of such proposed transfer.  Such written notice shall be by registered or certified mail, return receipt requested.  The notice shall describe the proposed transfer and state the name and address of the proposed transferee, the number of Shares to be transferred (the “Offered Shares”), and the price, terms of payment and conditions of such proposed transfer.  The written notice shall have attached to it a copy of the bona fide written offer received by the Transferring Party from the proposed transferee.

(c)           SSB’s, DST’s, and Clarke & Tilley’s Option.  The parties receiving the notice described in paragraph 3(b) shall have the exclusive option for a period of thirty (30) days after receipt of such notice, upon written notice to the Transferring Party to elect to purchase all, but not less than all, of the Offered Shares for the purchase price and upon the terms set forth in the bona fide written offer and the written notice from the

2

Transferring Party.  Each of the Non-Transferring Parties shall have an option to purchase a proportional amount (based on the number of Shares owned by each) of the Offered Shares; if either Non-Transferring Party declines to purchase any of its amount of the Offered Shares, the Other Non-Transferring Party may purchase all of the Offered Shares which the other declines to purchase.  The notice of acceptance by the Non-Transferring Parties or either of them shall specify a date for the closing of the purchase, which date shall not be more than forty-five (45) days after the date of the giving of such notice.

(d)           Transfer by Transferring Party Upon Failure of the Non-Transferring Parties to Exercise Option.  The Transferring Party may, within ninety (90) days following the end of the 45 day option period specified in paragraph 3(c), transfer Shares not purchased pursuant to the option, and which were the subject of the bona fide written offer, to the proposed transferee (but not to any other transferee) in accordance with the price, terms and conditions set forth in the written notice and bona fide offer described in paragraph 3(b) hereof.  If the Transferring Party fails to consummate the proposed transfer within the prescribed ninety (90) day period, it must again comply with all of the terms and provisions of this Agreement before transferring any of its Shares.

(e)           Involuntary Transfers.  In the event of any involuntary transfer of all or part of the Shares of any party the (“Transferring Party”), including by reason of attachment garnishment, by operation of law or pursuant to the order or direction of any court or tribunal (an “Involuntary Transfer”), the other parties (the “Non-Transferring Parties”) shall have an option to purchase all but not less than all of the Shares of the Transferring Party at a price equal to the Fair Market Value of Shares within 30 days after actual notice of the Involuntary Transfer.  Each of the Non-Transferring Parties shall have an option to purchase a proportional amount (based on the number of Shares owned by each) of the Transferring Party’s Shares; if either Non-Transferring Party declines to purcha se any of its amount of the Transferring Party’s Shares, the other Non-Transferring Party may purchase all of such Shares which the other declines to purchase.  The notice of exercise of option by the Non-Transferring Parties or either of them shall specify a date for the closing of the purchase, which date shall not be more than forty-five (45) days after the date of the giving of such notice.  The “Fair Market Value of Shares” for purposes of this Section 3(e) shall be determined by averaging the fair market value

3

established for the Shares by one independent appraiser selected by the party or parties desiring to purchase the shares (the “Purchaser”) and one independent appraiser selected by the Transferring party; provided, however, that if the fair market value established for the Shares by one of such appraisers is 110% or more of the fair market value established for the shares by the other appraiser, the Purchaser and the Transferring Party shall jointly select a third independent appraiser, such third appraiser shall be selected according to the rules at the time in effect of the American Arbitration Association, and the fair market value of the Shares shall be determined by averaging the fair market values established by the third appraiser and the two original appraisers.  The costs and expenses of the appraiser selected by the Purchaser shall be borne by the Purchaser and the costs and e xpense of the appraiser selected by the Transferring Party shall be borne by the Transferring Party.  The costs and expenses of the third appraiser, if required, shall be borne equally by the Purchaser and the Transferring Party.

(f)            Continuation of Restriction.  After the consummation of any transfer of Shares by the Transferring Party (including but not limited to transfers by written consent of the Non-Transferring Parties or pursuant to paragraph 3(d) above and involuntary transfers), the Shares so transferred shall continue to be subject to the terms and provisions of this Agreement, and this Agreement shall continue in full force and effect.  If any transferee of the Transferring Party’s Shares shall thereafter desire to transfer any Shares, such transferee shall be required to comply with all the terms and provisions of this Agreement before making such transfer.  The transferee of any shares or any interest in any Shares shall not be entitled to receive certificates for such shares unless and until said transfe ree shall have executed an instrument satisfactory to SSB, DST and Clarke & Tilley evidencing the transferee’s agreement that the transferee is bound by all of the terms and conditions hereof.

4.                                       Put and Call Option.  After December 31, 1995, if either SSB, DST or Clarke & Tilley desires to sell all of its Shares, such party (the “Offerer”) shall have the following option:

(a)           To establish a per share price payable in cash (the “Offering Price”) for all of the other parties’ Shares;

(b)           To submit to the other parties in writing an offer which offers to purchase all of the other parties’ Shares at the Offering Price times the number of Shares owned by

4

the other parties or to sell all of the Offeror’s Shares at the Offering Price times the number of Shares owned by the Offeror;

(c)           Each of the parties receiving such an offer shall have 30 days from the receipt of the offer either to accept the offer to purchase its Shares or to elect to purchase its pro-rata share of the Offeror’s Shares at the Offering Price times the number of Shares to be sold (each party’s “pro-rata share” shall be the percentage determined by dividing the number of Shares owned by such party by the total number of Shares outstanding after excluding the Shares owned by the Offeror).

(d)           Should the parties receiving the offer specified in paragraph 4(b) elect to purchase the Offeror’s Shares, the Offeror shall be bound by such election and must sell to the other parties at such offering price;

(e)           In the event both parties receiving the offer described in paragraph 4(b) fail to respond as provided in paragraph 4(c), both parties shall be deemed to have accepted the Offeror’s offer to purchase all of both such parties’ Shares on the last day of the time period provided in paragraph 4(c);

(f)            In the event one of the parties receiving the offer described in paragraph 4(b) elects to purchase its pro-rata shares of the Offeror’s Shares, and other party receiving such offer elects to sell its shares in response to the offer described in paragraph 4(b), then the party electing to purchase shall have 10 days immediately following the 30 day period indicated in paragraph 4(c) to elect to purchase all of the Offeror’s Shares and all of the Shares of the party electing to sell its Shares pursuant to the offer described in paragraph 4(b).  If the party electing purchase declines to purchase all such Shares within such 10 day period, then both parties shall be deemed to have accepted the Offeror’s offer to purchase all of the such parties’ Shares.

(g)           Within 30 days after the acceptance of the offer to purchase or the election to purchase, the selling party shall tender certificates for all of the Shares purchased and other appropriate transfer documents to the purchasing party or parties, in proper form for transfer of all of the selling party’s Shares free and clear of all liens and encumbrances, and the purchasing party or parties shall deliver to the selling party the Offering Price (as described in the offer) times the number of Shares purchased in exchange for such certificates and other appropriate transfer documents.
