This irrevocable proxy is given in support of the voting agreement set forth in the following paragraph and is coupled with an interest, and is irrevocable (to the full extent permitted by the General Corporation Law of the State of Delaware).  As used herein, the term “Proxy Term” shall mean the period commencing upon the execution of this irrevocable proxy and ending immediately following the conclusion of the Special Meeting.

During the Proxy Term, each of the Proxyholder and the undersigned hereby agree, for good and valuable consideration, to vote their respective Shares in favor of the proposals referred to in the Demand for Special Meeting attached as Exhibit A to this irrevocable proxy and against any proposals reasonably likely to defeat, hinder, or delay the such proposals.

The attorneys and proxies named above are hereby authorized and empowered by the undersigned, at any time during the Proxy Term, to act as the undersigned’s attorney and proxy to vote the Shares, and to exercise all voting and other rights of the undersigned with respect to the Shares at the Special Meeting, and any adjournments or postponements thereof.  In addition to the other covenants and agreements of the undersigned provided for elsewhere in this irrevocable proxy, during the Proxy Term, the undersigned shall not enter into any agreement, arrangement or understanding with any natural person or entity to take any of the actions described in this irrevocable proxy and voting agreement, or the effect of which would be inconsistent with or violate the provisions and agreements contained in this irrevocable proxy and voting agreement.

Any obligation of the undersigned hereunder shall be binding upon the successors, heirs, agents, representatives, transferees and assigns of the undersigned.

The undersigned agrees to take, at the Proxyholders’ request, all reasonable steps necessary (including issuing instructions, notices or other documents) to cause any person or entity through whom the undersigned holds its Shares (including brokers, nominees, etc.) to execute such legal proxies, affidavits and other documents to effectuate the purposes of this irrevocable proxy and the voting agreement herein contained (including without limitation to cause such Shares to be voted in the manner required by the voting agreement and to cause a proxy to be granted to the Proxyholder to vote such Shares in the manner contemplated by the voting agreement).

For purposes of this voting agreement and irrevocable proxy, “Special Meeting” means the special meeting of stockholders of the Company at which the stockholders of the Company vote on the proposals referred to in the Demand for Special Meeting attached as Exhibit A hereto, including any adjournments or postponements of such special meeting.

The undersigned hereby revokes all proxies previously made by the undersigned regarding any Share.

For purposes of this voting agreement and irrevocable proxy, references to the “undersigned” do not refer to the Proxyholder.

This voting agreement and irrevocable proxy can be executed in one or more counterparts, all of which shall be considered together one and the same document.

This Agreement is governed by the laws of the State of Delaware.
