(b)               Restrictions on Transfers. Until the earlier of the receipt of the Requisite Company Vote or the Termination Time, the Stockholder shall not, directly or indirectly, sell, offer to sell, give, pledge, grant a security interest in, encumber, assign, grant any option for the sale of or otherwise transfer or dispose, enter into any swap or other arrangement that hedges or transfers to another, in whole or in part, any of the economic consequences of ownership of, or enter into any agreement, arrangement, contract or understanding to take any of the foregoing actions with respect to (each, a “Transfer”), any Shares, other than a Transfer of Shares (x) by will or operation of law as a result of the death of the Stockholder, in which case, this Agreement shall bind the transferee, (y) for bona fide estate planning purposes to the Stockholder’s (i) affiliates (as defined in the Merger Agreement) or (ii) immediate family members (each, a “Permitted Transferee”), or (z) by or at the direction of the holder of a Lien (as defined below) as required by the terms of such Lien; provided that, in the case of the foregoing subclauses (x) and (y) only, as a condition to such Transfer, such Permitted Transferee shall be required to duly execute and deliver to Parent a joinder to this Agreement (in form and substance reasonably satisfactory to Parent); provided, further, that, in the case of the foregoing subclause (y) only, the Stockholder shall remain jointly and severally liable for any breaches or violations by any such Permitted Transferee of the terms hereof. Any Transfer of Shares in violation of this Section 1(b) shall be null and void. The Stockholder further agrees to authorize and request the Company to notify the Company’s transfer agent that there is a stop transfer order with respect to all of the Shares owned by the Stockholder and that this Agreement places limits on the Transfer of the Stockholder’s Shares.

If any controlled affiliate of the Stockholder acquires Shares by way of a Share Acquisition, the Stockholder will cause such controlled affiliate to comply with the terms of this Agreement applicable to the Stockholder.

(e)               No Inconsistent Agreements. Until the Termination Time, the Stockholder shall not enter into any agreement, arrangement, contract or understanding with any person (as defined in the Merger Agreement), directly or indirectly, to vote, grant a proxy or power of attorney or give instructions with respect to the voting of the Shares in any manner that is inconsistent with the terms of this Agreement.

The failure of any party to exercise any right, power or remedy provided under this Agreement or otherwise available in respect hereof at law or in equity, or to insist upon compliance by any other party with its obligations hereunder, and any custom or practice of the parties at variance with the terms hereof, shall not constitute a waiver by such party of its right to exercise any such or other right, power or remedy or to demand such compliance.
