2. Award of Restricted Shares

   2.1    Award of Restricted Shares. Pursuant to the terms of the Plan, as of the Date of Grant, [______] Common Shares (the "Restricted Shares") shall be issued as hereinafter provided in Participant's name subject to certain restrictions thereon. The Restricted Shares shall be issued upon acceptance hereof by Participant and upon satisfaction of the conditions of this Agreement. Participant acknowledges receipt of a copy of the Plan, and agrees that this award of Restricted Shares shall be subject to all of the terms and provisions of the Plan, including future amendments thereto, if any, pursuant to the terms thereof.

3. Forfeiture Restrictions and Lapse of Forfeiture Restrictions

    

   3.1    Forfeiture Restrictions. The Restricted Shares may not be sold, assigned, pledged, exchanged, hypothecated or otherwise transferred, encumbered or disposed of to the extent then subject to the Forfeiture Restrictions, and in the event of termination of Participant's Service for any reason whatsoever other than death or Disability, Participant shall, for no consideration, forfeit to the Company all Restricted Shares that are then subject to the Forfeiture Restrictions. The prohibition against transfer and the obligation to forfeit and surrender Restricted Shares to the Company upon termination of Service (other than by reason of death or Disability) are herein referred to as the "Forfeiture Restrictions." The Forfeiture Restrictions shall be binding upon and enforceable against any transferee of Restricted Shares.

   3.2    Lapse of Forfeiture Restrictions. Provided that Participant has been continuously in Service from the Date of Grant through the lapse date described in this sentence, the Forfeiture Restrictions shall lapse with respect to one-sixth (1/6^th) of the Restricted Shares on each of the first six annual anniversaries of the Vesting Start Date. Notwithstanding the schedule described in the preceding sentence, except to the extent previously forfeited under Section 3.1, if Participant's Service terminates for any reason whatsoever on the date upon which a Change in Control occurs and Participant has been continuously in Service from the Date of Grant until such termination, then an Acceleration Event shall be deemed to occur upon such termination and the Forfeiture Restrictions shall lapse as to all of the Restricted Shares then subject to the Forfeiture Restrictions.

   3.3    Service Relationship. For purposes of this Agreement, any question as to whether and when there has been a termination of Participant's Service, and the cause of such termination, shall be determined by the Committee, and its determination will be final. Without limiting the scope of the preceding sentence, it is expressly provided that Participant shall be considered to have terminated Service at the time of the termination of the "Subsidiary" status under the Plan of the entity or other organization that employs Participant.

4. Certificates, Corporate Acts and Status of Stock

    

   4.1    Certificates.  A certificate evidencing the Restricted Shares not then subject to Forfeiture Restrictions (pursuant to Section 3.2 above) shall be issued by the Company in Participant's name, pursuant to which Participant shall have all of the rights of a shareholder of the Company with respect to the Restricted Shares, including, without limitation, voting rights and the right to receive dividends (provided, however, that dividends paid in shares of the Company's stock shall be subject to the Forfeiture Restrictions). Upon the lapse of the Forfeiture Restrictions without forfeiture, the Company shall cause a certificate or certificates to be issued without legend (except for any legend required pursuant to applicable securities laws or any other agreement to which Participant is a party) in the name of Participant. For purposes of clarification only: certificates for Restricted Shares shall not be issued until such time as the Forfeiture Restrictions have lapsed without forfeiture (pursuant to Section 3.2 above), and until such time, the Restricted Shares shall be evidenced only by book-entry in the Company's records.

   4.2    Corporate Acts. The existence of the Restricted Share awards shall not affect in any way the right or power of the Board or the shareholders of the Company to make or authorize any adjustment, recapitalization, reorganization or other change in the Company's capital structure or its business, any merger or consolidation of the Company, any issue of debt or equity securities, the dissolution or liquidation of the Company or any sale, lease, exchange or other disposition of all or any part of its assets or business or any other corporate act or proceeding; provided, however, that in the event of a stock split, stock dividend paid in shares, or similar reorganization affecting all or substantially all of the Company's shares, the Restricted Shares shall similarly and automatically be split or reorganized without further action or decision by the Company or the Committee. The prohibitions of Section 3.1 shall not apply to the transfer of Restricted Share awards pursuant to a plan of reorganization of the Company, but the stock, securities or other property received in exchange therefor shall also become subject to the Forfeiture Restrictions and provisions governing the lapsing of such Forfeiture Restrictions applicable to the original Restricted Shares for all purposes of this Agreement.

   4.3    Status of Stock. Participant agrees that the Restricted Shares will not be sold or otherwise disposed of in any manner which would constitute a violation of any applicable federal or state securities laws. Participant also agrees that (i) the certificates representing the Restricted Shares may bear such legend or legends as the Committee deems appropriate in order to assure compliance with applicable securities laws, (ii) the Company may refuse to register the transfer of the Restricted Shares on the stock transfer records of the Company if such proposed transfer would constitute a violation of the Forfeiture Restrictions or, in the opinion of counsel satisfactory to the Company, of any applicable securities law, and (iii) the Company may give related instructions to its transfer agent, if any, to stop registration of the transfer of the Restricted Shares.

5. Miscellaneous

    

   5.1    Notices. For purposes of this Agreement, notices and all other communications provided for herein will be in writing and will be deemed to have been duly given when personally delivered or (i) if Participant is outside of the United States at the time of transmission of such notice, when sent by courier, facsimile, or electronic mail, and (ii) if Participant is within the United States at the time of transmission of such notice, when mailed by United States registered or certified mail, return receipt requested, postage prepaid, addressed to the Company at its principal executive office and to Participant at the last address filed with the Company or to such other address as either party may furnish to the other in writing in accordance herewith, except that notices of changes of address will be effective only upon receipt.

   5.2    Withholding of Tax. To the extent that the receipt of the Restricted Share awards or the lapse of any Forfeiture Restriction results in compensation income or wages to Participant for federal, state or local tax purposes, Participant shall deliver to the Company at the time of such receipt or lapse, as the case may be, such amount of money or Common Shares as the Company may require to meet all obligations under applicable tax laws or regulations, and, if Participant fails to do so, the Company is authorized to withhold or cause to be withheld from any cash or stock remuneration then or thereafter payable to Participant any tax required to be withheld by reason of such resulting compensation income or wages.

   5.3    No Employment Rights Conferred. No provision of this Agreement shall confer any right upon Participant to continued employment with the Company or any Subsidiary.

   5.4    Limitation of Rights. No provision of this Agreement shall be construed to give Participant or any other person any interest in any fund or in any specified asset or assets of the Company or a Subsidiary (other than the Restricted Shares after the Forfeiture Restrictions therefore have lapsed).

   5.5    Binding Effect. This Agreement shall be binding upon and inure to the benefit of any successors to the Company and all persons lawfully claiming under Participant.

   5.6    Governing Law.  This Agreement shall be governed by, and construed in accordance with, the laws of the state of Texas.

IN WITNESS WHEREOF, the Company has caused this Agreement to be duly executed by its officer thereunto duly authorized, and Participant has executed this Agreement, all effective as of the Date of Grant.
