By way of clarification and not limitation, the Grantees may exercise the Put Option as of the last Business Day of any given quarter within a Put Period for as many Shares as it may determine subject to the above maximums (for example, the Grantees may, but are not required to, exercise the Put Option for the entire 2,333,333 Shares for the First Put Period, in the first quarter). If at the last day of the First Put Period, Second Put Period or Third Put Period, as the case may be, Grantees have not exercised the Put Option with respect to any of the Shares allocable to such Put Period, the Grantees' right to exercise the Put Option and to require the Grantors to purchase such Shares shall expire, subject to the Grantees' right, in the event of a Standoff, to carry-over any Shares to the remaining quarters of the Put Term, as 5 CUSIP No. 82655N105 13D Page 13 of 25 Pages described in Section 2.02 below. The Grantors obligations to acquire Shares shall be up to the following maximum amounts: (a) Tabacchi and his Permitted Grantor Transferees shall be obligated to purchase and acquire up to an aggregate of 5,600,000 Shares, except that Tabacchi and his Permitted Grantor Transferees shall not be required to purchase such shares at any Put Closing (as hereafter defined) if the aggregate purchase price for all Shares purchased by Tabacchi and its Permitted Grantor Transferees would then exceed $4,000,000, and (b) La Sesta and its Permitted Grantor Transferees shall be obligated to acquire up to an aggregate of 1,400,000 Shares except that La Sesta and its Permitted Grantor Transferees shall not be required to purchase such shares at any Put Closing if the aggregate purchase price for all Shares purchased by La Sesta and its Permitted Grantor Transferees would then exceed $1,000,000. The Grantors shall have no rights or interests in any Shares that are not purchased and paid for by them. SECTION 2.02 Put Period and Standoff. The Put Option shall continue in effect during the Put Term and all Extensions thereof, except that if as of the last day of any quarter during the Put Period the index for the national market of the Nasdaq Stock Market, Inc. ("Nasdaq") or any successor thereto, as reported by Nasdaq, has increased (i) by 60% or more during the prior six-month period as reported for the first day of such six-month period and the last day of such six-month period, or (ii) by 120% or more during the prior 12 month period as reported for the first day of such 12--month period and the last day of such 12-month period (collectively, the "Standoff Conditions"), the Put Option relating to such quarter shall not be exercisable by any Grantee (each case being a "Standoff"). If a Standoff shall be in effect at the end of the First Put Period, Second Put Period or Third Put Period, as the case may be, the Grantees shall carry-over any unexercised Shares (the "Carry-Over Shares") allocable to such Put Period, by reallocating those Carry-Over Shares on a pro-rata basis to the remaining Put Periods during the Put Term; provided, that if any Standoff is in effect as of the end of the Third Put Period, the Put Term shall be extended by successive full quarters (each an "Extension" and together the "Extensions") until such time as such Standoff Conditions shall be no longer in effect. Following each Standoff, the Put Option shall resume being exercisable by the Grantees on each date that the Standoff shall no longer be in effect. In the final quarter of an Extension, the Grantees shall have the right to exercise the Put Option, and, if so exercised, the Grantors shall have the obligation to purchase, all remaining Shares that have not yet been purchased by the Grantors. SECTION 2.03 Put Notice. The Put Option may be exercised in the sole discretion of each Grantee by delivering written notice ("Put Notice") of exercise to the Grantor as of the last day of each quarter within a Put Period. The Put Notice shall indicate the number of Shares each Grantee is putting to the Grantors. Upon receipt of a Put Notice in accordance with the terms hereof, the applicable Grantees shall be obligated to sell all of the Shares to which the Put Notice relates, free and clear of all liens and encumbrances created by each of them or their respective Affiliates (other than pursuant to this Agreement). The Grantors shall be obligated to purchase pro rata all of such Shares put by the applicable Grantees, at the applicable Put Price in accordance with, and subject to, the terms of this Agreement; provided, however, that the Put Option may not be exercised if 6 CUSIP No. 82655N105 13D Page 14 of 25 Pages the Standoff Conditions have occurred and are continuing. For purposes of the foregoing sentence, the "pro rata" portion of Shares that Tabacchi and its Permitted Grantor Transferees on the one hand, and La Sesta and its Permitted Grantor Transferees on the other hand, shall be obligated to purchase, shall mean a fraction, (A) the numeration of which shall be 5,600,000 in the case of Tabacchi and his Permitted Grantor Transferees, and 1,400,000 in the case of La Sesta and its Permitted Grantor Transferees and the (B) denominator of which shall be 7,000,000, subject to the aggregate limitations set forth in Section 2.01 of this Agreement. SECTION 2.04 Put Price; Closing and Limitation on Shares. (a) The "Put Price" at which the Put Shares shall be sold to the Grantors shall be the Fair Market Value determined as of the last day of each quarter for which the Put Option has been exercised. Notwithstanding anything herein to the contrary, the Put Price shall not (a) exceed $1.00 per share, and (b) be less than $0.20 per share, provided, further, that the Put Price at which the first 2,333,333 Shares sold to and purchased by the Grantors during the last five quarters of the Put Term shall be not less than $0.30 per share. (b) The Grantees shall be obligated to sell, and the Grantors shall be obligated to pay the purchase price for and acquire, the Shares being sold and purchased pursuant to each Put Notice at the Put Closing (as hereafter defined). The closing of the purchase and sale of Shares pursuant to each Put Option, shall take place at the principal office of Carlyle or at such other location as the Parties shall mutually agree, on a Business Day to be mutually agreed upon by the Grantors and the Grantees, which date shall be no later than 30 days following the last day of the quarter during which the Put Notice was delivered, or if the Parties do not mutually agree to a closing date, the closing date shall be the next Business Day following such thirtieth day (each a "Put Closing"); provided, however, that if the purchase of Shares is subject to prior regulatory approval, the Grantors and Grantees will use their reasonable best efforts to obtain the necessary regulatory approvals and the Put Closing shall be postponed until the expiration of five Business Days after the date that all such regulatory approvals shall have been received. At each Put Closing, the Grantees shall deliver to the Grantors the certificates representing the Shares being sold pursuant to the exercise of such Put Option, duly endorsed or accompanied by stock powers executed in blank, in form and substance customary in the United States of America for transactions of this type, and evidence reasonably satisfactory to the Grantor that the Shares are being transferred free and clear of all liens and encumbrances created by such Grantee or its Affiliates (it being understood that in no event shall a Grantee be obligated to make any representations and warranties, or to provide any indemnities, with respect to (i) any matters relating to the Company, or (ii) with respect to any other matters other than (1) title to the Shares held by such Grantee, such title being free and clear of all liens and encumbrances created by it or its Affiliates, (2) such Grantee's authority, authorization and right to enter into and consummate the sale without contravention of any law or agreement, and without the need for any third party consent or approval (not including any governmental or regulatory consent or approval which shall have been applied for or received), and (3) the existence of pending or, to the knowledge of the Grantee, threatened litigation involving such Grantee that could reasonably be expected to prohibit or limit the sale of good title to the Shares by such Grantee). At each Put Closing, the Grantors shall pay the Put Price to each Grantee by delivery of cash by wire transfer to the accounts of the applicable Grantees. 7 CUSIP No. 82655N105 13D Page 15 of 25 Pages (c) Notwithstanding anything in Section 2.04(b) to the contrary, if Grantees exercise their Put Option (including Excess Exercised Shares, as defined below, if any, carried over from the previous quarter) for more than an aggregate of 777,777 Shares as of the last day of a quarter that is not the last day of the First Put Period, Second Put Period or Third Put Period, or any Extension thereof, as the case may be, the Put Closing and payment of the Put Price for such number of Shares in excess of 777,777 (the "Excess Exercised Shares") shall take place at a date not later than 30 days following the first to occur of (i) the end of the next quarter during which Put Notices exercising the Put Option for fewer than an aggregate of 777,777 Shares (including Excess Exercised Shares) have been delivered to the Grantors, or (ii) the end of the next quarter that shall be the last quarter of a Put Period, it being understood that no payment shall be required to be made for more than 777,777 Shares for any quarter in any Put Period, except for the last quarter in each Put Period at which time the Grantors shall be obligated to purchase all Excess Exercised Shares from the Grantees. (d) If any of the Grantors do not pay the full amount of the Put Price for all Shares to be purchased by such Grantors at any Put Closing or during the Put Period, Article III, Right of First Refusal, immediately shall terminate and no longer be in effect, and, at the Grantees' option, in their sole discretion, the Grantees may (i) withdraw the exercise of the Put Option with respect to such Shares, in which case they would retain all rights and obligations with respect thereto, (ii) deem the exercise of the Put Option to remain in effect, in which case, if the Grantors do not pay the Put Price within 30 days of the date of the Put Notice, the Put Price shall double, and (iii) exercise all of their other rights and remedies, in law and in equity, pursuant to this Agreement and otherwise. The Grantors and Grantees acknowledge and agree that this Section 2.05 does not constitute a liquidated damages provision or a penalty. SECTION 2.05 Assignment. Tabacchi and La Sesta may assign their respective rights and obligations to purchase the Shares pursuant to the Put Option to their respective Permitted Grantor Transferees. Notwithstanding an assignment of the Put Option by Tabacchi or La Sesta, as the case may be, Tabacchi and La Sesta shall remain primarily liable for all payment and performance obligations of the Grantors under the Put Option and this Agreement. SECTION 2.06 Exercise of Put Option Not a Transfer. None of the exercises by Grantees of the Put Option, nor the consummation of the transactions contemplated thereby, shall constitute a Transfer that is subject to the Right of First Refusal set forth in Article III of this Agreement (by way of example and not limitation, the sale of shares by a Grantee pursuant to the Put Option to a Permitted Grantor Transferee, shall not require any Grantee to comply with the Right of First Refusal provisions of Article III). ARTICLE III RIGHT OF FIRST REFUSAL SECTION 3.01 Right of First Refusal. 8 CUSIP No. 82655N105 13D Page 16 of 25 Pages (a) During the Put Period, prior to selling any Shares to a third party, Carlyle agrees that upon receipt of a bona fide written binding offer (subject only to this Right of First Refusal) from a third party (the "Proposed Transferee"), Carlyle shall submit a written offer (the "Offer") to sell all Shares proposed to be purchased by the Proposed Transferee (the "Offered Shares"), on terms and conditions, including price, not less favorable than those on which Carlyle proposes to sell such Offered Shares to the Proposed Transferee, to Tabacchi and La Sesta (the "Offerees"). (b) The rights of each Offeree shall be in addition to and not in substitution of its rights and obligations under the Put Option. (c) The Offer shall disclose the number of Offered Shares proposed to be sold, the terms and conditions (including price) of the proposed sale, and any other material facts relating to the proposed sale. The Offer shall further state that the Offerees may acquire, in accordance with the provisions of this Agreement, the Offered Shares for the price and upon the other terms and conditions set forth therein. SECTION 3.02 Notice of Intent to Purchase. If the Offerees exercise their right to acquire the Offered Shares, such right may only be exercised to acquire all such Offered Shares and not a portion of such Offered Shares. If the Offerees desire to purchase the Offered Shares offered to them, they shall communicate in writing their election to purchase all the Offered Shares (the "Right of First Refusal Exercise Notice") to Carlyle no later than 20 days after the date of the Offer (the parties providing such Right of First Refusal Exercise Notice, are sometimes referred to hereafter individually, as a "Purchaser," and collectively as, the "Purchasers"). If an Offeree declines to purchase, or otherwise defaults and fails to purchase, any Offered Shares, in order for the remaining Offerees to have the right to acquire Offered Shares, such remaining Offerees shall be required to acquire the declining Offeree's allotment of Offered Shares (the "Over-Allotment Right"), in whole and not in part, and such Offerees shall provide written notice to Carlyle specifying the number of additional Offered Shares it will acquire pursuant to the Over-Allotment Right. Such Right of First Refusal Exercise Notice shall, when taken in conjunction with the Offer, be deemed to constitute a valid, binding and enforceable agreement for the sale and purchase of the Offered Shares. SECTION 3.03 Offered Shares Closing. The closing of the purchase and sale of Offered Shares pursuant to the Offer, shall take place no later than 30 days following the date of the Right of First Refusal Exercise Notice at the principal office of Carlyle or at such other location as the Parties shall mutually agree, on a Business Day to be mutually agreed to by Carlyle and the Purchasers or if the Parties do not mutually agree to a closing date, the closing date shall be the next Business Day following such fifteenth day (the "Offered Shares Closing"), provided that if the purchase of Offered Shares is subject to prior regulatory approval, Carlyle and the Purchasers will use their reasonable best efforts to obtain the necessary regulatory approvals and the Offered Shares Closing shall be postponed until the 9 CUSIP No. 82655N105 13D Page 17 of 25 Pages expiration of five Business Days after the date that all such regulatory approvals shall have been received, except that if such regulatory approvals are not received within 60 days following the date of the Right of First Refusal Exercise Notice, Carlyle shall have the right to sell the Offered Shares pursuant to Section 3.04 below. At the Offered Shares Closing, Carlyle shall deliver to the Purchasers the certificates representing the Offered Shares duly endorsed or accompanied by stock powers executed in blank, in form and substance customary in the United States of America for transactions of this type to the Purchasers, and evidence reasonably satisfactory to the Purchasers that the Offered Shares are being transferred free and clear of all liens and encumbrances created by Carlyle or its Affiliates (it being understood that in no event shall a Grantee be obligated to make any representations and warranties, or to provide any indemnities, with respect to (i) any matters relating to the Company, or (ii) with respect to any other matters other than (1) title to the Shares held by such Grantee, such title being free and clear of all liens and encumbrances created by it or its Affiliates, (2) such Grantee's authority, authorization and right to enter into and consummate the sale without contravention of any law or agreement, and without the need for any third party consent or approval (not including any governmental or regulatory consent or approval which shall have been applied for or received), and (3) the existence of pending or, to the knowledge of the Grantee, threatened litigation involving such Grantee that could reasonably be expected to prohibit or limit the sale of good title to the Shares by such Grantee). At the Offered Shares Closing, the Purchasers shall pay the purchase price for the Offered Shares to Carlyle in such amount and on such payment terms as set forth in the Offer. SECTION 3.04 Sale to Third Party. If the Purchasers do not exercise this Right of First Refusal in whole, or do not offer to purchase all of the Offered Shares, the Offered Shares may be sold by Carlyle at any time within three months after the date the Offer was made. Any such sale shall be to the Proposed Transferee on terms and conditions not materially different than those specified in the Offer. If any Offered Shares are not sold within the three month period or if the terms of the Offer shall change, the Offered Shares shall be subject to renewed compliance with the requirements of the Right of First Refusal pursuant to Section 3.01. Any third party to whom Shares are sold shall have no rights or obligations under this Agreement. None of the provisions of this Article III shall be applicable to, nor shall prohibit, the offer and sale of any Offered Shares in open market transactions on any exchange, market system or bulletin board on which shares of Common Stock are quoted, or offers and sales of the Shares can be made, from time to time, and pursuant to the exercise of registration rights under the Registration Rights Agreements with the Company to which the Grantees are party covering Shares.

Tabacchi, La Sesta and their Permitted Grantor Transferees on the one hand, and Carlyle on the other hand, agree that the rights, powers and remedies given to each other Party by this Agreement are cumulative and concurrent and not exclusive of any thereof or of any other powers, rights or remedies available to such Party, whether existing at law or in equity of by statute or otherwise, and shall be in addition to every other right, power or remedy provided in this Agreement, and the exercise or beginning of the exercise by such Party of any one or more of such rights, powers and remedies shall not preclude the simultaneous or later exercise by such Party of any or all such other rights, powers and remedies. No failure on the part of any Party to exercise any right, power or remedy shall operate as a waiver thereof. SECTION 4.03 Entire Agreement.
