Restriction on Transfers of shares ---------------------------------- 7.1 The "B" Shareholder agrees that it will not transfer any of its shares to a Party who is not an Affiliate of such Shareholder subject to the consent of the "A" Shareholder, which consent may not be unreasonably withheld.

The "B" Shareholder will have the right to participate solely on a pro-rata basis in the sale to the third party (i.e., if the "A" Shareholder receives an offer to sell 40% of its shares, the "B" Shareholder's rights exists as to 20% of its holdings and the "A" Shareholder may not be able to sell more than 20% of its holdings).

The principal amount of Loan from the "B" Shareholder to the Company will be due and payable when the loan from the "A" Shareholder to the Company is repaid. Interest will accrue on the Loan on a daily basis to the "B" Shareholder at the "Prime Rate" of interest charged by the Harris Trust & Savings Bank, Chicago, Illinois, plus 3%, and will be calculated monthly.

Thereafter, any excess interest will be paid to the "B" Shareholder. (ii) The Company shall lend the Loan Amount to the "A" Shareholder on an interest-free basis. The loan shall be without recourse to the "A" Shareholder. The loan to the "A" Shareholder will be due and payable if and only if: i) the "A" Shareholder transfers all of his remaining shares to an unrelated third party; or ii) the Company is liquidated. The "A" shareholder will pledge his shares to the Company to secure the Loan Amount. 7.4 Change of Owner "A" Shares. --------------------------- If the "A" Shareholder sells all of its shares of the Company or if Mr. Lee S. Casty or his Affiliates cease to own more than 33-1/3% of the "A" Shareholder, then: i) the "B" shares will automatically be converted into "A" shares; ii) the "B" Shareholder will be issued 1 share of the "A" stock of the Company without payment of further consideration; and iii) thereafter, the Company will be required to distribute at least 80% of its available cash flow, after providing for reasonable reserves, to the shareholders of the Company, unless the "B" Shareholder 7 consents in writing to take a smaller amount. 8.

Wellesley or Naldini commences employment with or becomes an officer, director or the owner of 5% or more of the equity of an organization that is engaged in the same business activities as the Company (in which case the "B" Shareholder shall be deemed to be the "Defaulting Shareholder") or if either Shareholder or its affiliates (in such case, the "Defaulting Shareholder") shall: (i) commit a material breach or shall commit persistent breaches of this Agreement which are not capable of remedy, or if capable of remedy, have not been so remedied within 21 Business Days of the other Shareholder (the "Other Shareholder") serving notice on the Defaulting Shareholder requiring such remedy; (ii) cease to trade or have a receiver, administrative receiver, administrator or manager appointed over its affairs, become insolvent or go into liquidation (unless such liquidation is for the purposes of a solvent reconstruction or amalgamation) compound with its creditors generally or be otherwise unable to meet its debts as they fall due; (iii) fail to comply with any resolution of the Company taken at a properly constituted meeting of Shareholders or Directors, then the Other Shareholder may (but shall not be obligated to), without prejudice to any other rights and remedies which the Other Shareholder may have, serve a written 8 notice on the Defaulting Shareholder (a "Default Notice") at any time during the period of 60 Business Days following an Event of Default coming to the notice of the Other Shareholder. 8.3 The Default Notice shall specify a date (being not less than 5 Business Days nor more than 15 Business Days after the date of service of the Default Notice), time and place for completion of the sale and purchase of the Defaulting Shareholders' Shares. The purchase price for such shares shall equal the book value of the shares held by the Defaulting Shareholder (reduced, in the case of the "B" shares by the amount for which the "B" shares have not been fully paid up). 8.4 Any Shares sold pursuant to this Clause 8 shall be transferred free from any claims, equities, liens and encumbrances whatsoever and with all rights attaching to the relevant Shares as at the date of service of the Default Notice, but without the benefit of any other warranties or representations whatsoever. 8.5 If neither Shareholder serves a Default Notice in accordance with the foregoing provisions following one of the events specified in (i) - (iii) of Clause 8.2.1, then the Other Shareholder shall have the unilateral right to cause the Board, at the earliest practicable date, to: (a) make or concur in the making of a statutory declaration in the terms mentioned in section 89 if the Insolvency Act 1986 of the state of the Company's affairs admits to the making of such declaration); (b) subsequently convene an extraordinary general meeting for the purpose of passing (and each Shareholder will vote in favor of) an extraordinary resolution to place the Company in members' voluntary liquidation (if such a declaration as is mentioned in clause 8.5(a) above has been made) or (in any other case) in creditors' voluntary liquidation such meeting or meetings to be held within 5 weeks after the making of any declaration made in pursuance of clause 8.5(a) above; and (c) where the state of the Company's affairs does not admit the making of such a declaration as is mentioned in clause 8.5(a) above, convene a meeting of the Company's creditors in accordance with section 98 of the Insolvency Act 1986. 9 8.6 Each of the Shareholders appoints the other (or any Director nominated by that other) irrevocably, and by way of security for the performance of its obligations under this Clause 8, as its attorney, to execute any necessary document, including, without limitation, any transfer of Shares. 8.7 Upon a transfer of the Shares held by a Shareholder in accordance with this clause: (a) the transferring Shareholder shall pay up any unpaid share capital (whether previously called or not) and repay all loans, loan capital, borrowings and indebtedness in the nature of borrowings outstanding to the Company from that Shareholder (together with any accrued interest thereon); (b) the Company or the other Shareholder shall repay all loans, loan capital, borrowings and interest in the nature of borrowings outstanding to the transferring Shareholder from the Company (together with any accrued interest thereon); (c) the transferring Shareholder shall procure the removal of any Directors or Secretary of the Company appointed by it; and (d) the transferring Shareholder shall co-operate by doing all such things and executing all such documents as the purchasing Shareholder may reasonably require to procure that the Company shall adopt new Articles of Association in such form as the purchasing Shareholder may require. 8.8 The rights of the Parties under this Clause 8 shall be without prejudice to any claim any party may have against any other for damages for breach of contract. 9.
