Item 5. Other Events.

      On September 7, 2001, Veeco Instruments Inc., a Delaware corporation
("Veeco"), announced that it had entered into an Agreement and Plan of Merger
(the "Merger Agreement"), dated as of September 6, 2001, with Veeco Acquisition
Corp., a Minnesota corporation and wholly-owned subsidiary of Veeco
("Acquisition"), Applied Epi, Inc., a Minnesota corporation ("Applied Epi"), the
shareholders of Applied Epi listed on the signature pages thereto and Paul E.
Colombo, as Stockholders' Representative. Pursuant to the Merger Agreement,
Acquisition will be merged with and into Applied Epi with the result that the
surviving corporation will be a wholly-owned subsidiary of Veeco. Pursuant to
the Merger Agreement, each share of Applied Epi's common stock issued and
outstanding immediately prior to the effective time of the merger shall be
converted into the right to receive 0.184 shares of Veeco common stock. Applied
Epi shareholders will have the right to elect to receive all or any portion of
the merger consideration in cash, provided that no more or less than $29.8
million of the total value of the merger consideration will be paid in cash.
Consummation of the transaction is subject to customary closing conditions
including, among others, approval by Applied Epi's shareholders and required
regulatory approvals.

      The purchase price for the transaction was determined by arms-length
negotiations among the respective parties. The merger will be accounted for
using the purchase method of accounting and is expected to close by the end of
September 2001.

      On September 7, 2001 Veeco issued a press release announcing the signing
of the Merger Agreement.
