For purposes of this Agreement, a "Corporate Transaction" shall mean any of the following events: (i) the consummation of any merger or consolidation of the Company in which the Company is not the continuing or surviving corporation, or pursuant to which shares of Common Stock are converted into cash, securities or other property, if following such merger or consolidation the holders of the Company's outstanding voting securities immediately prior to such merger or consolidation own less than a majority of the outstanding voting securities of the surviving corporation; (ii) the consummation of any sale, lease, exchange or other transfer in one transaction or a series of related transactions of all or substantially all of the Company's assets, other than a transfer of the Company's assets to a majority-owned subsidiary of the corporation; (iii) the approval by the holders of the Common Stock of any plan or proposal for the liquidation or dissolution of the Company; or (iv) the acquisition by a person, within the meaning of Section 3(a)(9) or of Section 13(d)(3) (as in effect on the date of adoption of the Plan) of the Exchange Act of a majority or more of the Company's outstanding voting securities (whether directly or indirectly, beneficially or of record), other than a person who held such majority on the date of adoption of the Plan. Ownership of voting securities shall take into account and shall include ownership as determined by applying Rule 13d-3(d)(1)(i) (as in effect on the date of adoption of the Plan) pursuant to the Exchange Act.

For purposes of this Agreement, "Good Reason" shall mean, without your prior written consent, any of the following events or conditions and the failure of the surviving corporation, the successor corporation or its parent corporation, as applicable (the "Successor Corporation") to cure such event or condition within thirty (30) days after receipt of written notice from you: (i) a substantial diminution or material adverse change in your status, title, position, authority, duties or responsibilities (including reporting responsibilities) as in effect immediately prior to a Corporate Transaction, except in connection with your Termination for Cause, disability or death or by you other than for Good Reason; (ii) a reduction in your annual base salary; (iii) the Successor Corporation's failure to cover you under employee benefit plans, programs and practices that, in the aggregate, provide substantially comparable benefits (from an economic perspective) to you relative to the benefits and total costs under the material employee benefit plans, programs and practices in which you (and/or your family or dependents) are participating immediately preceding the Corporate Transaction; (iv) the Successor Corporation's requiring you to be based at any office location that is more than fifty (50) miles further from your office location immediately prior to a Corporate Transaction, except for reasonable required travel for the Successor Corporation's business that is not materially greater than such travel requirements prior to such Corporate Transaction; or (v) a material breach by the Successor Corporation of its obligations to you under the Plan.

6. Retention of Certificates. Promptly after the date first written above (the "Grant Date"), the Company will recognize your ownership of the Restricted Stock through uncertificated book entry, another similar method, or issuance of stock certificates representing the Restricted Stock.

7. Rights with Regard to Restricted Stock. You will have the right to vote the Restricted Stock to receive and retain all regular cash dividends payable to other shareholders of record on and after the Grant Date (although such dividends will be treated, to the extent required by applicable law, as additional compensation for tax purposes), and to exercise all other rights, powers and privileges of a holder of Common Stock with respect to the Restricted Stock set forth in the Plan, except: (i) you will

not be entitled to delivery of any unvested Restricted Stock, and the Company (or its designated agent) will retain custody of any such shares; (ii) no part of the Restricted Stock will bear interest or be segregated in separate accounts; and (iii) you may not Transfer any unvested Restricted Stock.
