3.2 Legend. All certificates representing Securities issued to a Shareholder shall bear the following legend in addition to any other legend required by law or by another provision of this or any other agreement:

“THE SALE, TRANSFER, ASSIGNMENT, PLEDGE OR ENCUMBRANCE OR ANY OTHER ALIENATION OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE AND THE RIGHTS OF THE HOLDERS OF SUCH SECURITIES IN RESPECT OF THE ELECTION OF DIRECTORS AND OTHER MATTERS ARE SUBJECT TO THE TERMS AND CONDITIONS OF A SHAREHOLDER VOTING AND CONTROL AGREEMENT DATED AS OF AUGUST 31, 1999. COPIES OF SUCH AGREEMENT MAY BE OBTAINED AT NO

4

COST BY WRITTEN REQUEST MADE BY THE HOLDER OF

RECORD OF THIS CERTIFICATE TO THE SECRETARY OF

THE COMPANY.”

“THE SECURITIES EVIDENCED BY THIS CERTIFICATE

HAVE NOT BEEN REGISTERED UNDER THE SECURITIES

ACT OF 1933 AND MAY NOT BE SOLD OR TRANSFERRED

UNLESS THERE IS AN EFFECTIVE REGISTRATION

STATEMENT COVERING SUCH SECURITIES OR THE

COMPANY RECEIVES AN OPINION OF COUNSEL (WHICH

COUNSEL AND OPINION ARE REASONABLY

SATISFACTORY TO THE COMPANY) STATING THAT SUCH

SALE OR TRANSFER IS EXEMPT FROM THE

REGISTRATION AND PROSPECTUS DELIVERY

REQUIREMENTS OF SUCH ACT.”

3.3 Certain Restrictions. Notwithstanding any other provision of this Agreement to the contrary, no Transfer of Securities (other than a Public Transfer (as defined in Section 3.4 below) or a Transfer pursuant to Section 4.1) may be effected unless and until the intended transferee(s) has agreed to be bound by the provisions of this Agreement (including, without limitation, those related to Transfers, the Bring-Along Rights, the Tag-Along Rights; and the Right of First Refusal to the extent then applicable), in writing in a form reasonably satisfactory to Carlyle. Each such transferee shall succeed to the obligations, and the rights, of the transferring Shareholder hereunder.

3.4 Exempt Transfers. The provisions of Article 4 shall not apply to the Transfer (an “Affiliate Transfer”) of Securities by a Shareholder to any of its Affiliates (including transfers without consideration from a Shareholder to its partners, members or stockholders), provided that the provisions of Section 3.3 have been strictly complied with.

ARTICLE 4.

BRING-ALONG RIGHTS; TAG-ALONG RIGHTS; RIGHT OF FIRST REFUSAL

4.1 Bring-Along Rights.

(a) In the event that Carlyle propose to Transfer at least 50% of the outstanding shares of Common Stock (or rights to acquire Common Stock) of the Company to an unaffiliated third party or parties (“Third Party”), then Carlyle shall have the right (a “Bring-Along Right”), but not the obligation, to cause any other Shareholders to tender for purchase to the Third Party, on the same terms and conditions as apply to Carlyle, a pro rata number of shares of Common Stock held by such other Shareholder.

(b) If Carlyle elects to exercise its Bring-Along Right under this Article 4, then it shall so notify the other Shareholders (“Bring-Along Notice”). Each Bring-Along Notice shall set forth: (i) the name of the Third Party or Third Parties and the number of shares of Common Stock proposed to be purchased by such Third Party or Third Parties, (ii) the proposed amount and form of consideration and terms and conditions of payment offered by the Third Party and a summary of any other material terms pertaining to the Transfer (“Third Party Terms”) and (iii) the number of shares of Common Stock that such other Shareholder is required to sell in such Transfer. The Bring-Along Notice shall be given at least ten (10) days before the closing of the proposed Transfer.

(c) Upon the giving of a Bring-Along Notice, each such other Shareholder shall be obligated to sell the number of shares of Common Stock required to be sold by Carlyle as set forth in the Bring-Along Notice on the Third Party Terms.

(d) At the closing of the Transfer to any Third Party pursuant to this Article 4, the Third Party shall remit to each Shareholder the consideration for the total sales price of the Common Stock of such Shareholder sold pursuant hereto, against delivery by such Shareholder of certificates for such Common Stock, duly endorsed for Transfer or with duly executed stock powers, and the compliance by such Shareholder with any other conditions to closing generally applicable to such Shareholders selling shares in such transaction.

4.2 Tag-Along Rights.

(a) Carlyle (a “Selling Shareholder”) agrees that it shall not Transfer any shares of Common Stock held by such Selling Shareholder to a Third Party (other than in Exempt Transfers, to which the provisions of this Section 4.2 do not apply), unless the terms and conditions of such Transfer shall include an offer to each of the other Shareholders to include in the transfer to the Third Party, at such other Shareholder’s option and on the Third Party Terms (as defined below), an amount of the shares of Common Stock determined in accordance with Section 4.2(c) (the “Tag-Along Rights”).

(b) The Selling Shareholder shall deliver notice to the Company and notify each other Shareholder of any proposed Transfer to which the provisions of this Section 4.2 apply (a “Sale Notice”). Each Sale Notice shall set forth: (i) the name of the Third Party and the number of shares of Common Stock proposed to be transferred, (ii) the address of the Third Party, (iii) the proposed amount and form of consideration and terms and conditions of payment

6

offered by the Third Party and any other material terms pertaining to the Transfer (the “Third Party Terms”), and (iv) that the Third Party has been informed of the Tag-Along Rights provided for in this Section 4.2 and has agreed to abide by the terms of the Tag-Along Rights.

(c) Following delivery of a Sale Notice, each of the other Shareholders shall have the option to sell to the Third Party on the Third Party Terms an amount of shares of Common Stock equal to the number of shares of Common Stock owned by such other Shareholder equaling the lesser of (x) the number derived by multiplying (i) the total number of shares of Common Stock to be purchased by the Third Party by (ii) a fraction, the numerator of which is the aggregate number of shares of Common Stock owned by such other Shareholder and the denominator of which is the number of shares of Common Stock then owned in the aggregate by GE Equity, Carlyle and any of their Affiliate Transferees or (y) such lesser number of shares as the other Shareholder shall designate in the Tag-Along Notice (defined below). The Tag-Along Rights set forth in this Section 4.2(c) may be exercised by any other Shareholder by delivery of a written notice to the Company and the Selling Shareholder (the “TagAlong Notice”) within ten (10) days following receipt of a Sale Notice (the “Tag-Along Period”). The Tag-Along Notice shall state the number of shares of Common Stock that such other Shareholder wishes to include in such transfer to the Third Party. Upon the giving of a Tag-Along Notice, such other Shareholder shall be entitled and obligated to sell the number of shares of Common Stock set forth in the Tag-Along Notice to the Third Party on the Third Party Terms; provided, however, that neither the Selling Shareholder nor any such other Shareholder shall consummate the sale of any shares offered by it if the Third Party does not purchase all shares which the Selling Shareholder and other Shareholders are entitled and desire to sell pursuant hereto.

At the closing of the Transfer to any Third Party (of which the Selling Shareholder shall give each other Shareholder who has elected to exercise the Tag Along Right provided by this Section 4.2(b) at least five business days’ prior written notice), the Third Party shall remit to each Shareholder the consideration for the total sales price of the shares of Common Stock of such Shareholder sold pursuant thereto, against delivery by such Shareholder of certificates for such shares of Common Stock, duly endorsed or with duly executed stock powers and the compliance by such Shareholder with any other conditions to closing generally applicable to the Selling Shareholder and all other Shareholders selling shares in such transaction.

(d) If the provisions of this Section 4.2 have been complied with in all respects, the Selling Shareholder shall have the right for a 180-day period following delivery of the Sale Notice to transfer the shares of Common Stock to the Third Party on the Third Party Terms (or on other terms no more favorable to the Selling Shareholder) without further notice to other Shareholders who have not given a Tag-Along Notice, but after such 180-day period no such transfer may be made without again giving notice to all other Shareholders of the proposed transfer and complying with the requirements of this Section 4.2.

4.3 Right of First Offer.

(a) (1) If any Shareholder other than Carlyle, or any Affiliate Transferee of Carlyle or any other successor or assign of Carlyle (each a “Right of First Offer Shareholder”) desires to Transfer any or all of its shares of Common Stock or any rights to such shares (collectively the “Transfer Stock”) to any Third Party (other than in Exempt Transfers or

7

sales under Section 4.1 above, to which the provisions of this Section 4.3 do not apply), such Right of First Offer Shareholder shall reduce to writing (the “Transfer Notice”) the terms pursuant to which it desires to issue or Transfer such Transfer Stock (a “Transfer Offer”). Such Transfer Notice shall identify the Transfer Stock and the consideration for the Transfer Stock. The Right of First Offer Shareholder shall provide the Transfer Notice to the Company and the Company shall promptly, but in no event later than five (5) Business Days following receipt of the Transfer Notice from the Right of First Offer Shareholder, provide written notice (dated the day it is given) of such Transfer Offer to all other Shareholders (the “Transfer Offerees”). The Transfer Notice shall constitute an irrevocable offer by the Right of First Offer Shareholder (“First Offer”) to sell the Transfer Stock to the Transfer Offerees at a price equal to the price contained in the Transfer Notice. The Transfer Offerees shall have the irrevocable right and option (the “Right of First Offer”) to accept the First Offer as to any or all shares of Common Stock of the Transfer Stock pursuant to the Transfer Offer. Each Transfer Offeree that desires to purchase any Transfer Stock shall provide the Right of First Offer Shareholder with an irrevocable written notice specifying the number of shares of Common Stock of the Transfer Stock which such Transfer Offeree is requesting to purchase pursuant to such Transfer Offer (including the number of shares in excess of such Transfer Offeree’s pro rata portion of the Transfer Stock (the “Excess Shares”)), which shall be binding on said Transfer Offeree for the number of shares of Common Stock in such notice of acceptance, or the lesser number of shares allocated pursuant to Section 4.3(aX2), within thirty (30) Business Days after the date of the Transfer Notice (the “Notice Period”), and shall simultaneously provide a copy to the Company. The Company shall promptly distribute such notice of acceptance to all Transfer Offerees.

(2) The allocation of Transfer Stock to Transfer Offerees pursuant to a Transfer Offer shall be made as follows:

(i) Each Transfer Offeree is entitled to purchase a number of Shares of the Transfer Stock pro rata with all other Transfer Offerees based on the respective holdings (on a fully diluted basis) of Shares of each Transfer Offeree as of the date of such Transfer Offer.

(ii) If every Transfer Offeree requests to purchase a number of shares of Common Stock of Transfer Stock equal to or greater than such Transfer Offeree’s pro rata portion, then each Transfer Offeree shall be entitled to only receive such Transfer Offeree’s pro rata portion of the Transfer Stock.

(iii) If such Transfer Offer is undersubscribed and any Transfer Offeree requests to purchase a number of shares of Common Stock equal to or less than its respective pro rata portion of the Transfer Stock, each Transfer Offeree shall (x) first, be entitled to receive the number of shares of Transfer Stock requested for purchase by such Transfer Offeree or, if less, the number of shares of Transfer Stock equal to such Transfer Offeree’s pro rata portion of the Transfer Stock, and (y) second, with respect to any Transfer Offeree requesting Excess Shares, receive that number of additional shares of Common Stock equal to the lesser of (A) the number of Excess Shares such Transfer Offeree requested and (B) such Transfer Offeree’s allocable portion of all Excess Shares based on the respective number of Shares held at the time of the Transfer Offer by each Transfer Offeree who requested Excess

8

Shares, applied on an iterative basis to the extent that any such Transfer Offeree’s request shall be satisfied in full without all Excess Shares being allocated.

(b) The closing of the purchases of the Transfer Stock by the Transfer Offerees that have exercised the options granted pursuant to this Section 4.3 shall take place at the principal office of the Company on the date specified in the Transfer Offer (which date shall not be less than thirty (30) business days following the date of the Transfer Notice). At such closing, such Transfer Offerees shall deliver a certified check or checks in the appropriate amount to the Right of First Offer Shareholder against delivery of certificates representing the Transfer Stock so purchased, duly endorsed in blank for transfer or accompanied by a stock power duly executed in blank. In the event that the consideration specified in the Transfer Offer is other than cash, then such Transfer Offerees, may, at their option, deliver at such closing cash, in lieu of such other consideration, in an amount equal to the fair market value of such other consideration (as agreed upon by the parties or as determined by an independent appraisal).

(c) If the provisions of this Section 4.3 have been complied with in all respects, the Right of First Offer Shareholder shall have the right for a 120-day period following delivery of the Transfer Notice to transfer the shares of Transfer Stock to the Third Party on the terms set forth in the Transfer Notice (or on other terms no more favorable to the Right of First Offer Shareholder) without further notice to the Transfer Offerees, but after such 120-day period no such transfer may be made without again giving notice to Transfer Offerees of the proposed transfer and complying with the requirements of this Section 4.3.

ARTICLE 5.

COMPANY SALE

5.1 If the Board of Directors and the holders of a majority of the outstanding shares of Common Stock approve a Company Sale (as defined below), each Shareholder agrees that he shall consent and raise no objections to such Company Sale, and if the Company Sale is structured as a sale of stock, each Shareholder shall sell all or any portion of the share of Common Stock in connection with such Company Sale on the terms and conditions approved by the Board of Directors and the holders of a majority of the outstanding shares of Common Stock. Each Shareholder hereby agrees to take all actions that the Board of Directors and the holders of a majority of the outstanding shares of Common Stock reasonably deem necessary or desirable in connection with the consummation of such Company Sale, including, without limitation, voting the shares of Common Stock in favor of such Company Sale and refraining from the exercise of statutory dissenters’ rights with respect to such Company Sale; provided that each Shareholder shall receive the same consideration per share for each share of Common Stock held by such Shareholder.

5.2 Shareholders shall bear their pro-rata share (based upon the number of shares held by Shareholder that are sold in such Company Sale) of the costs of any sale of Common Stock pursuant to a Company Sale to the extent such costs are incurred for the benefit of all holders of Common Stock and are not otherwise paid by the Company or the acquiring party.

9

For the purpose hereof, “Company Sale” shall mean the consummation of any transaction or series of transactions pursuant to which one or more persons or entities or group of persons or entities acquires (i) capital stock of the Company possessing the voting power sufficient to elect a majority of the members of the Board of Directors of the Company or its successor(s) (whether such transaction is effected by merger, consolidation, recapitalization, statutory share exchange, sale or transfer of the Company’s capital stock or otherwise) or (ii) all or substantially all of the assets of the Company and its subsidiaries.
