As soon as practicable following the lapse of all forfeiture restrictions with respect to any shares of Restricted Stock, such shares shall be transferred to you in the name of a nominee in an account for you or, at your request, in the form of a certificate. Except for dividends, if any, payable to stockholders generally, you have no right to receive any payment in cash from the Company with respect to the Restricted Stock, either before or after such shares vest.

THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A RESTRICTION ON TRANSFER AND THE RISK OF FORFEITURE TO THE COMPANY AS PROVIDED IN A RESTRICTED STOCK AGREEMENT BETWEEN THE ISSUER AND THE REGISTERED OWNER OF THESE SECURITIES, A COPY OF WHICH IS ON FILE WITH THE ISSUER.

Shares of Restricted Stock awarded hereunder shall not be transferable by you until after an unlegended certificate has been issued to you as provided in this Section 8 with respect to such shares.

9. Taxes. The Compensation Committee (as defined in the Plan) may withhold delivery of certificates for shares of Restricted Stock until you make satisfactory arrangements to pay any withholding, transfer or other taxes due with respect to the transfer or vesting of such shares. You are responsible for the payment of all taxes applicable to any income realized upon the vesting of the shares of Restricted Stock on the date of vesting. Unless you provide written notice to the Company at least ten days prior to the vesting of your Restricted Stock that you will pay cash to settle your tax obligation, or unless otherwise determined by the Company in its sole discretion, settlement of your tax obligation shall be made by the Company by withholding and cancelling shares of Common Stock that would be otherwise issuable upon vesting of the Restricted Stock, with the fair market value of such Common Stock for such purposes equal to the closing price per share of Common Stock as generally reported on the Nasdaq Stock Market (or such other exchange or market where the Common Stock is trading) on the date of vesting of the Restricted Stock. If you elect to settle your tax obligation by paying cash and you do not make timely payment of your tax withholding obligation by cash or check on the date of vesting of this Restricted Stock, the Company may, in its sole discretion, satisfy your tax withholding obligation by withholding and cancelling shares of Common Stock that would be otherwise issuable upon vesting of the Restricted Stock in the manner set forth in this Section 9.

The Company also shall withhold from dividends any amount required to be withheld by any governmental entity.

10. Adjustments. Subject to Section 3 above, if there is any change in the Common Stock by reason of stock dividends, split-ups, mergers, consolidations, reorganizations, combinations or exchanges of shares or the like, the number of shares of Restricted Stock previously awarded to you pursuant to this Agreement shall be adjusted appropriately so that the number of shares of Restricted Stock held by you pursuant to this Agreement after such an event shall equal the number of shares of Common Stock a stockholder would own after such an event if the stockholder, at the time such an event occurred, had owned shares of Common Stock equal to the number of shares of Restricted Stock awarded to you pursuant to this Agreement before such an event.

11. Interpretations Binding. The interpretations and determinations of the Compensation Committee are binding and conclusive. This Agreement is entered into in Missouri and its terms shall be governed by and interpreted in accordance with the laws of the State of Missouri without regard to conflicts of law principles.

12. No Right to Continue as an Employee; No Right to Further Awards. This Agreement does not give you any right to continue as an employee of the Company or any of its subsidiaries for any period of time or at any rate of compensation, nor does it interfere with the Company’s or its subsidiaries’ right to determine the terms of your employment. An award of Restricted Stock is within the discretion of the Compensation Committee, and does not entitle you to any further awards of Restricted Stock.

13. Jurisdiction. Any suit or other legal action to enforce the terms of this Agreement or any document or agreement referenced herein must be brought in the St. Louis County, Missouri Circuit Court or (if federal jurisdiction exists) the U.S. District Court for the Eastern District of Missouri. You agree that venue and personal jurisdiction are proper in either such court, and waive all objections to jurisdiction and venue and any defense or claim that either such forum is not the most convenient forum.

14. Forfeiture of Restricted Stock; Recoupment. You understand and agree that your right to receive and retain the Restricted Stock granted herein (and the benefits thereof) is conditioned on your compliance with the terms of this Agreement and any agreement referenced herein. In the event you violate this Agreement or any other agreement referenced herein, then in addition to and not in lieu of any other rights and remedies available to the Company for such breach, all of which are expressly reserved, the Company may (i) declare a forfeiture of, and cancel, all shares of Restricted Stock; and (ii) recover from you any and all shares of common stock for which all restrictions have lapsed pursuant to this Agreement, or an amount equal to the value of the same, with such value being the fair market value of the common stock at the close of business on the date all applicable restrictions on the Restricted Stock lapsed.
