This letter is intended to reflect the terms and conditions of a retention bonus arrangement (the “Agreement”) between you and Crane Merger Co. (the “Company”).

In order to encourage you to remain in the employ of the Company following the closing of the transactions contemplated by the Merger Agreement, you will be eligible to receive certain cash retention payments under the terms set forth in this Agreement.

This Agreement will be effective as of, and contingent upon the occurrence of, the Effective Time as defined in and as provided under the Merger Agreement and, in the event that the Merger Agreement is terminated for any reason prior to the closing of the Merger, this Agreement will have no further force or effect.
