WHEREAS, this Agreement is executed and the transactions contemplated hereby are consummated simultaneously with the Stock Purchase.

NOW THEREFORE, the parties hereto agree as follows:

Section 1. Authorization of Issuance and Sale of Securities.

1A. Issuance of Securities. The Company shall (prior to Closing, as defined below) authorize the issuance and sale to the Purchasers of:

(i) The number of shares of its Class B Common Stock, par value $.01 per share (the “Class B Common”), Class L Common Stock, Series 3, par value $.01 per share (the “Class L-3 Common”) and Class L Common Stock, Series 4, par value $.01 per share (the “Class L-4 Common” and together with the Class B Common and the Class L-3 Common, collectively referred to as the “Common Stock”), each having the rights and preferences set forth in the Amended and Restated Articles of Incorporation (the “Articles of Incorporation”) attached as Exhibit A hereto, set forth opposite such Purchaser’s name on the Schedule of Purchasers; and

(ii) The number of warrants to subscribe for and purchase shares of Class L-3 Common (the “L-3 Warrants”), set forth opposite such Purchaser’s name on the Schedule of Purchasers, each such L-3 Warrant subject to the terms and conditions set forth in the Form of Warrant attached as Exhibit B hereto.

The L-3 Warrants and the Common Stock issued by the Company to the Purchasers hereunder are collectively referred to herein as the “Securities”.

Section 2. Purchase and Sale of Securities.

2A. Purchase and Sale. On the basis of the representations, warranties, covenants and agreements set forth herein, but subject to the terms and conditions set forth herein, at the Closing the Company shall sell to each Purchaser and each Purchaser shall purchase from the Company, the number of shares of Common Stock and L-3 Warrants set forth

opposite such Purchaser’s name on the Schedule of Purchasers, for the aggregate purchase price for each such Purchaser as set forth therein. The sale of the Securities to each Purchaser shall constitute a separate sale hereunder and the obligations of each Purchaser hereunder shall be several rather than joint.

2B. The Closing. The closing of each separate sale and purchase of the Securities (the “Closing”) shall take place at the offices of Kirkland & Ellis LLP, 200 East Randolph Drive, Chicago, IL 60601, on September         , 2003, or at such other place or on such other date as may be mutually agreeable to the Purchasers and the Company. At the Closing, the Company shall deliver to each Purchaser a certificate or certificates evidencing the number of shares of each class of Common Stock and L-3 Warrants to be purchased by such Purchaser, registered in such name as such Purchaser shall designate, against payment of the purchase price therefor by wire transfer of immediately available funds to a bank account designated by the Company.

Section 3. Restrictions on Transfers.

3A. Restrictions. Restricted Securities are only transferable pursuant to (i) public offerings registered under the Securities Act, (ii) Rule 144 or Rule 144A of the Securities and Exchange Commission (or any similar rules then in force) if such rules are available, and (iii) subject to the conditions specified in Section 3B below, any other legally available means of transfer pursuant to the Securities Act.

3B. Procedure for Transfer. In connection with the transfer of any Restricted Securities (other than a transfer referred to in clauses (i) or (ii) of Section 3A above), the holder thereof will deliver written notice to the Company describing in reasonable detail the transfer or proposed transfer, together with an opinion of Kirkland & Ellis LLP or other counsel which (to the Company’s reasonable satisfaction) is knowledgeable in securities law matters to the effect that such transfer of Restricted Securities may be effected without registration of such Restricted Securities under the Securities Act. In addition, if the holder of such Restricted Securities delivers to the Company an opinion of such counsel that no subsequent transfer of such Restricted Securities will require registration under the Securities Act, the Company will promptly upon such contemplated transfer deliver new certificates for such Restricted Securities which do not bear the Securities Act Legend set forth in Section 3D below. If the Company is not required to deliver new certificates for such Restricted Securities not bearing such Securities Act Legend, the holder thereof will not transfer the same until the prospective transferee has confirmed to the Company in writing its agreement to be bound by the conditions contained in this Section and Section 3D.

THE TRANSFER OF SUCH SECURITIES IS SUBJECT TO THE CONDITIONS SPECIFIED IN THE SECURITIES PURCHASE AGREEMENT, DATED AS OF SEPTEMBER          2003, BETWEEN THE ISSUER (THE “COMPANY”) AND CERTAIN INVESTORS, AND THE COMPANY RESERVES THE RIGHT TO REFUSE TO TRANSFER SUCH SECURITIES UNTIL SUCH CONDITIONS HAVE BEEN FULFILLED WITH RESPECT TO SUCH TRANSFER. UPON WRITTEN REQUEST, A COPY OF SUCH CONDITIONS WILL BE FURNISHED BY THE COMPANY TO THE HOLDER HEREOF WITHOUT CHARGE.”

In addition, to the extent applicable, each certificate evidencing the Securities issued hereunder and each certificate issued in exchange for or upon the transfer of any of the Securities (if such Securities remain “Shareholder Shares” (as defined in the Company’s Amended and Restated Shareholders Agreement, dated as of the date hereof (the “Shareholders Agreement”)) after such transfer) shall be stamped or otherwise imprinted with a legend in substantially the following form:

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN TRANSFER AND VOTING RESTRICTIONS PURSUANT TO THE AMENDED AND RESTATED SHAREHOLDERS AGREEMENT DATED AS OF SEPTEMBER         , 2003, AMONG THE ISSUER OF SUCH SECURITIES (THE “COMPANY”) AND CERTAIN OF THE COMPANY’S STOCKHOLDERS.
