Ownership by the Participant of not more than one percent (1%) of the shares of any corporation having a class of equity securities actively traded on a national securities exchange shall not be deemed, in and of itself, to violate the prohibitions set forth in this Section 16.

Non-Solicitation of Clients:

Miscellaneous:

The Participant specifically acknowledges and agrees that the provisions of this Section 16 are reasonable and necessary to protect the legitimate interests of the Company and its Affiliates and that the Participant desires to agree to the provisions of this Section 16. In the event that any of the provisions of this Section 16 should ever be held to exceed the time, scope or geographic limitations permitted by applicable law, it is the intention of the parties that such provision be reformed to reflect the maximum time, scope and geographic limitations that are permitted by law.

The Participant acknowledges and agrees that, owing to the special, unique and extraordinary nature of the matters covered by this Section 16, in the event of any breach or threatened breach by the Participant of any of the provisions hereof, the Company or any of its Affiliates would suffer substantial and irreparable injury, which could not be fully compensated by monetary award alone, and the Company and its Affiliates would not have adequate remedy at law. Therefore, the Participant agrees that, in such event, the Company or any of its Affiliates will be entitled to seek temporary and/or permanent injunctive relief against the Participant, without the necessity of proving actual damages or of posting bond to enforce any of the provisions of this Section 16, and the Participant hereby waives the defenses, claims, or arguments that the matters are not special, unique, and extraordinary, that the Company or any such Affiliate must prove actual damages, and that the Company or such Affiliate has an adequate remedy at law. In addition, the Participant shall pay to the Company or such Affiliate and the Company or such Affiliate shall be awarded the reasonable attorney’s fees and costs incurred by such entity as a result of the Participant’s breach of the Participant’s obligations in this Section 16.

The rights and remedies described in this Section 16 are cumulative and are in addition to, and not in lieu of, any other rights and remedies otherwise available under the Restricted Stock Grant Notice and this Restricted Stock Agreement, or at law or in equity, including, but not limited to, monetary damages.

Notwithstanding any other provision of the Restricted Stock Grant Notice and this Restricted Stock Agreement, in the event of any breach by the Participant of any of the provisions of this Section 16, all obligations and liabilities of the Company under the Restricted Stock Grant Notice and this Restricted Stock Agreement shall immediately terminate and be extinguished. Further, in the event of any breach by the Participant of any of the provisions of this Section 16, the restrictive time periods set forth herein do not include any period of violation or period of time required for litigation to enforce the Restricted Stock Grant Notice and this Restricted Stock Agreement.

In the event the Company has a reasonable basis to believe that the Participant may be in breach of any of the provisions of this Section 16, the Company may suspend its obligations to the Participant under the Restricted Stock Grant Notice and this Restricted Stock Agreement until such time as the Participant provides the Company with (i) an undertaking to comply with the provisions of this Section 16 and (ii) an affidavit of compliance with the provisions of this Section 16, both in a form reasonably specified by the Company.

The Participant agrees to inform the Company of the name and address of any employer(s), as well as the Participant’s job title and duties with each employer that the Participant may have or any business with which the Participant may be involved, directly or indirectly, within the Non-competition Period.

The Company shall have the right to disclose the Restricted Stock Grant Notice and this Restricted Stock Agreement or its contents to any of the Participant’s future employers for the purpose of providing notice of the post-employment restrictions contained herein. The Company will provide the Participant with written notice if and when the Company discloses the existence of the Restricted Stock Grant Notice and this Restricted Stock Agreement to any future employer.
