                     POWER OF ATTORNEY AND IRREVOCABLE PROXY

         Reference is hereby made to that Certain Veeco Stockholders Voting
Agreement (the "VOTING AGREEMENT"), dated as of the date hereof, of which this
Veeco Stockholders Power of Attorney and Irrevocable Proxy (this "IRREVOCABLE
PROXY") forms a part. Capitalized terms used but not defined in this Irrevocable
Proxy have the respective meanings ascribed to such terms in the Voting
Agreement. This Irrevocable Proxy is being delivered by the undersigned Veeco
Stockholder (the "GRANTING STOCKHOLDER") pursuant to Section 3.3 of the Voting
Agreement.

         The undersigned Granting Stockholder hereby irrevocably appoints CVC,
Inc., a Delaware corporation ("CVC"), and each of CVC's officers and other
designees (each such Person, a "PROXYHOLDER") as the Granting Stockholder's
attorney-in-fact and proxy pursuant to the provisions of Section 212 of the
Delaware General Corporation Law, with full power of substitution, in the
Granting Stockholder's name, place and stead, to vote and otherwise act (by
written consent or otherwise) with respect to all of the Veeco Shares now owned
of record or Beneficially Owned by the Granting Stockholder and of which the
Granting Stockholder may hereafter acquire record or Beneficial Ownership, and
any other securities, if any (the "OTHER SECURITIES"), which the Granting
Stockholder is entitled to vote at any meeting of the stockholders of Veeco
(whether annual or special and whether or not an adjourned or postponed meeting)
or consent in lieu of any such meeting or otherwise:

                  (a) in favor of the Merger, the adoption by Veeco of the
         Merger Agreement and the issuance of Veeco Shares in the Merger, other
         matters relating to the approval of the terms of the Merger Agreement
         and each of the other transactions contemplated by the Merger
         Agreement; and

                  (b) against any proposal or transaction involving Veeco or any
         of its Subsidiaries if any such transaction or proposal would in any
         manner impede, frustrate, prevent or nullify the Merger, the Merger
         Agreement or any of the other transactions contemplated by the Merger
         Agreement; PROVIDED, HOWEVER, that nothing set forth in this paragraph
         (b) is intended or shall be construed to grant to any Proxyholder the
         right to vote or otherwise act (by written consent or otherwise) with
         respect to any Veeco Shares or Other Securities owned of record or
         Beneficially Owned by the Granting Stockholder (i) against any Superior
         Veeco Proposal or related Veeco Acquisition Transaction or (ii) in the
         election of any director of Veeco.

         THIS POWER OF ATTORNEY AND IRREVOCABLE PROXY IS IRREVOCABLE AND COUPLED
WITH AN INTEREST. The Granting Stockholder hereby revokes all other proxies and
powers of attorney with respect to Veeco Shares and the Other Securities that
the Granting Stockholder may have heretofore granted, and no subsequent proxy or
power of attorney shall be given or written consent executed (and if given or
executed, shall not be effective) by the Granting Stockholder with respect
thereto. All authority herein conferred or agreed to be conferred shall survive
the death or incapacity of the Granting Stockholder and any obligation of the
Granting Stockholder under this Irrevocable Proxy shall be binding upon the
heirs, personal representatives, successors and assigns of the Granting
Stockholder.

Agreement in accordance with its terms and (b) the Effective Time of the Merger.

         The undersigned Granting Stockholder hereby irrevocably appoints CVC,

(whether annual or special and whether or not an adjourned or postponed meeting)
or consent in lieu of any such meeting or otherwise:

                  (a) in favor of the Merger, the adoption by Veeco of the
         Merger Agreement and the issuance of Veeco Shares in the Merger, other
         matters relating to the approval of the terms of the Merger Agreement
         and each of the other transactions contemplated by the Merger

                  (b) against any proposal or transaction involving Veeco or any

         respect to any Veeco Shares or Other Securities owned of record or
         Beneficially Owned by the Granting Stockholder (i) against any Superior
