VEECO AND FEI SIGN DEFINITIVE MERGER AGREEMENT
INVESTOR Q&A


Q.  WHAT IS THE NAME OF THE NEW COMPANY?

A.  The new company will be named Veeco FEI Inc. and will continue to trade on
the Nasdaq market under the symbol VECO.


Q.  WHAT ARE THE TERMS OF THE TRANSACTION?

A.  Under the terms of the merger agreement, unanimously approved by the Boards
of Directors of both companies, FEI shareholders will receive 1.355 shares of
Veeco common stock for each share of FEI they own. Based on FEI's approximately
32 million diluted shares outstanding, FEI stockholders will receive
approximately 44 million Veeco FEI shares with a current value of approximately
$1 billion.


Q.  WHO WILL BE ON THE MANAGEMENT TEAM OF THE VEECO FEI?

A.  Ed Braun, Veeco's CEO, will be the CEO and President of Veeco FEI. Vahe
Sarkissian, FEI's Chairman and CEO, will be Chairman of the Board and Chief
Strategy Officer. Jack Rein, Executive Vice President and CFO of Veeco, will be
the CFO of Veeco FEI.

Veeco and FEI senior managements will work together on an integration plan,
which will be further detailed at the time of the transaction's close.


Q.  WHAT IS THE AMOUNT OF THE ONE-TIME MERGER OR RESTRUCTURING-RELATED
CHARGES?  HOW MUCH GOODWILL WILL BE CREATED AS A RESULT OF THE MERGER?  WILL
THERE BE A WRITE-OFF FOR IN-PROCESS RESEARCH AND DEVELOPMENT?  WHAT IS THE
EXPECTED AMOUNT OF ONGOING INTANGIBLE AMORTIZATION AND THE IMPACT ON EARNINGS?

A.  Veeco and FEI management expect the combined company's financial statements
to be impacted by treatment of purchase accounting on amortization expense, a
sizeable in-process R&D write-off, inventory capitalization and SAB 101 deferred
revenue recognition. These amounts are very fact sensitive and require time
consuming and detailed independent appraisals, which will be undertaken over the
next several months. Management will provide detailed information on these
accounting treatments upon completion of the merger.


                                       1


Q.  IS THE DEAL ACCRETIVE?

A.  Yes, the transaction is expected to be accretive to Veeco's current 2003
analyst consensus estimates on a pro-forma basis. The transaction is expected to
be dilutive to Veeco on a GAAP basis when including the expected impact of
purchase accounting on amortization expense, in-process R&D write-off, inventory
capitalization and SAB 101 deferred revenue RECOGNITION. Veeco FEI management
will provide further information on the expected impact of purchase accounting
on the combined company's financial statements upon completion of the merger.


Q.  DOES THIS CHANGE YOUR JUNE QUARTER REVENUE AND EPS GUIDANCE FOR
EITHER COMPANY?

A.  No. The announcement will not have any impact on the current quarter
guidance, as the transaction is not expected to close until the fourth quarter.
Veeco and FEI's unchanged second quarter 2002 guidance was provided in this
morning's press release. Both companies will provide stand-alone guidance for
the third quarter when announcing second quarter results in several weeks.


Q.  WHAT ARE YOUR PROJECTED REVENUE TARGETS OVER THE NEXT SIX QUARTERS?
HOW DO YOU EXPECT THE MERGER TO BE ACCRETIVE TO SALES GROWTH?

A.  Historically, both Veeco and FEI have been cautious in providing forward
looking guidance, especially in the recent market climate, providing it only on
a quarter to quarter basis. We will provide further guidance upon completion of
the merger.


Q.  WHAT TYPE OF SYNERGIES DO YOU ANTICIPATE GENERATING FROM THE MERGER?

A.  Veeco and FEI anticipate cost synergies of approximately $8-10 million
(on an annualized basis) resulting from integration of the company's sales
and support network, supplier management, and manufacturing and
administrative efficiencies.

Q.  HOW DOES THE REVENUE OF THE COMBINED COMPANY BREAK DOWN BY END
MARKET?

A.  Based upon last year's sales, Veeco FEI sales by market would have been
23% data storage, 28% semiconductor, 33% scientific research and 16%
telecommunications/ wireless. In the first quarter of 2002, the combined
company's sales would have been 20% data storage, 29% semi, 41% research and
10% telecom/wireless.

equipment and 66 percent for metrology. In the first quarter of 2002, the
combined company's sales would have been 27% process equipment and 73%
metrology.


Q.  ARE YOU PLANNING TO RAISE ADDITIONAL FINANCING AS PART OF THIS MERGER?

A.  No, not currently. Since this is a stock-for-stock deal, the merger
consideration will not require cash financing. Both companies have healthy
balance sheets: combined, Veeco FEI will have approximately $476 million in
cash and cash equivalents on the balance sheet.


Q.  DOES THE MERGER TRIGGER ANY IMPACT ON THE COMPANIES' CONVERTIBLE BONDS?
IF SO, WHAT?

company's convertible bonds. The conversion price for FEI's convertible debt

Q.  PLEASE REVIEW THE ACCOUNTING STRUCTURE - HOW DO WE MODEL GOING FORWARD?

A.  Veeco will be the surviving entity from an accounting standpoint. Under
purchase accounting rules, Veeco's historical financials will become Veeco FEI's

proxy within approximately three weeks of the announcement date. The mailing
date will depend on when we receive SEC clearance of the proxy/registration.


Q.  DO YOU PLAN TO WORK WITH ISS TO ENSURE A SUCCESSFUL VOTE?

A.  We will discuss the benefits and details of the merger with ISS and any
other investor or third-party intermediary who may require further
information in order to make an informed decision.

                                       4


Q.  DOES THIS MERGER SIGNIFY A STRATEGIC MOVE FOR VEECO AWAY FROM PROCESS
EQUIPMENT?

A.  No, while this merger will increase our Metrology sales, Veeco remains
committed to the Process Equipment product line. This merger will give the
combined company greater opportunities to cross-sell Process Equipment and
Metrology solutions to its core customer base.
