“Company”), Federico Pignatelli (“Mr. Pignatelli”), and each of Alexander K.
Arrow, Norman J. Nemoy, and Gregory E. Lichwardt (collectively with
Mr. Pignatelli, the “Directors”). Each of the Company and the Directors are
referred to herein as a “Party,” and collectively as the “Parties.”

RECITALS:

WHEREAS, the Company and the Directors have engaged in various discussions and
communications concerning the composition of the Company’s Board of Directors
(the “Board”) and the Company’s and leadership structure;

WHEREAS, the Company and each of the Directors have determined that the
interests of the Company and its stockholders would be best served at this time
by coming to an agreement with respect to the composition of the Board, as
provided in this Agreement.

NOW, THEREFORE, in consideration of the foregoing premises and the mutual
covenants and agreements contained herein, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
Parties, intending to be legally bound hereby, agree as follows:

1. Board Composition; Executive Chairman Position.

(a) Concurrent with the execution of this Agreement, the Company and each of the
Directors shall take all requisite actions, in accordance with the Fifth Amended
and Restated Bylaws of the Company (the “Amended Bylaws”), to appoint
Mr. Pignatelli as Chairman of the Board of the Company and vest with
Mr. Pignatelli all powers assigned to such office as set forth in Amended Bylaws
and to keep Mr. Pignatelli in such position and with the powers stated in the
Amended Bylaws until the earlier of (a) the time when Mr. Pignatelli no longer
serves as a director of the Company, (b) the time when Mr. Pignatelli resigns
from such position, and (c) the time when Mr. Pignatelli is removed from such
position in accordance with the Amended Bylaws; and

(b) The Company and each of the Directors agree to nominate Mr. Pignatelli for
re-election as a director at the annual meetings of stockholders held in 2014,
2015, and 2016 for purposes of electing directors.

(c) Each of the Directors and the Company agree that they will take any and all
requisite actions to carry out the foregoing, including acting as a Board and as
members of the Nominating and Corporate Governance Committee of the Board.

2. Specific Performance.

Each of the Parties acknowledges and agrees that irreparable injury to the other
Parties hereto would occur in the event any of the provisions of this Agreement
were not performed in accordance with their specific terms or were otherwise
breached and that such injury would not be adequately compensable in damages. It
is accordingly agreed that each of the Parties shall be entitled to specific
enforcement of, and injunctive relief to prevent any violation of, the terms
hereof, and that no other Party hereto will take any action, directly or
indirectly, in opposition to the moving party seeking such relief on the grounds
that any other remedy or relief is available at law or in equity.

3. Truthful Testimony; Notice of Request for Testimony.

Nothing in this Agreement is intended to or shall preclude any Party from
providing testimony that such Party reasonably and in good faith believes to be
truthful in response to a subpoena, court order, regulatory request or other
judicial, administrative or legal process reasonably believed by such Party to
be valid or otherwise as required by law. Each Party shall notify the relevant
other Parties in writing as promptly as practicable after receiving any such
request of the anticipated testimony and at least ten (10) days prior to
providing such testimony (or, if such notice is not possible under the
circumstances, with as much prior notice as is possible) to afford the other
Parties a reasonable opportunity to challenge the subpoena, court order or
similar legal process. Moreover, nothing in this Agreement shall be construed or
applied so as to limit any person from providing candid statements that such
Party reasonably and in good faith believes to be truthful to any governmental
or regulatory body or any self-regulatory organization.

4. Severability.

If any provision of this Agreement shall be held by any court of competent
jurisdiction to be illegal, void or unenforceable, such provision shall be of no
force and effect, but the illegality or unenforceability of such provision shall
have no effect upon the legality or enforceability of any other provision of
this Agreement.

or permitted to be given under the terms of this Agreement must be in writing
