         Veeco Instruments Inc. ("Veeco") is filing this Amended Current Report
on Form 8-K/A to amend the exhibit described in Item 7 below previously filed
with the Securities and Exchange Commission.

         Item 7.  Financial Statements, Pro Forma Financial Information and
                  Exhibits.

         On July 11, 2002, Veeco, a Delaware corporation, entered into an
Agreement and Plan of Merger (the "Merger Agreement") by and among Veeco,
Venice Acquisition Corp., an Oregon corporation and wholly owned subsidiary
of Veeco ("Acquisition"), and FEI Company ("FEI"), an Oregon corporation.
Pursuant to the Merger Agreement, Acquisition will merge with and into FEI,
with the result that FEI shall be the surviving corporation and shall become
a wholly-owned subsidiary of Veeco (the "Merger").

         On July 12, 2002, Veeco filed with the Securities and Exchange
Commission a Current Report on Form 8-K with respect to the Merger and the
transactions contemplated thereby (the "July 12 8-K"). In connection with the
Merger Agreement, Veeco entered into a Voting Agreement (the "Voting
Agreement"), dated as of July 11, 2002, among Veeco and certain stockholders
of FEI. A copy of the Voting Agreement was filed as Exhibit 2.2 to the July
12, 2002 8-K. This Amended Current Report on Form 8-K/A is being filed solely
to add two FEI stockholders, Jan C. Lobbezoo and Michael J. Attardo, as
signatories to the Voting Agreement, a copy of which has been attached hereto
as Exhibit 2.2.
