INDEPENDENT AUDITORS' REPORT

To the Boards of Directors and Stockholders of
  Applied Epi, Inc. and Subsidiaries
Saint Paul, Minnesota

We have audited the accompanying consolidated balance sheets of Applied Epi,
Inc. and Subsidiaries (the Company) as of December 31, 2000 and 1999 and the
related consolidated statements of operations, stockholders' equity, and cash
flows for the years then ended. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the consolidated
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Applied Epi, Inc.
and Subsidiaries as of December 31, 2000 and 1999 and the consolidated results
of their operations and their cash flows for the years then ended in conformity
with accounting principles generally accepted in the United States of America.

APPLIED EPI, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
YEARS ENDED DECEMBER 31, 2000 AND 1999
- --------------------------------------------------------------------------------

1.   NATURE OF BUSINESS AND BASIS OF PRESENTATION

     Applied Epi, Inc. (formerly Chorus Corporation) was incorporated in
     Minnesota in 1986 and was 81%- and 90%-owned by the Majority Stockholder
     at December 31, 2000 and 1999, respectively.  Applied Epi, Inc. (the
     Company) is a provider of epitaxial equipment and related components
     used to produce compound semiconductors for the fiber optic, wireless,
     and lighting and display markets, as well as other consumer
     applications.

     In 1992, Applied Epi International, Inc. (formerly Chorus International
     Corporation) was incorporated as an Interest Charge Domestic
     International Sales Corporation (IC-DISC).  Applied Epi International,
     Inc. was formed to perform foreign sales activities and to obtain tax
     benefits related to the Company's foreign sales.

     In 1993, Applied Epi Europe, Inc. (formerly EPI Europe, Ltd.) was
     incorporated as a Minnesota company.  Applied Epi Europe, Inc. was
     formed for the purpose of sales and distribution of the Company's
     products in Europe.

     In December 2000, the Board of Directors (the Board) declared a
     five-for-one stock split effective December 31, 2000. All stock option,
     performance unit, and share data have been restated to reflect the split.

     In September 2000, the Company entered into a tax-free transaction
     pursuant to Section 351 of the Internal Revenue Code and issued 122,005
     shares of common stock to the Majority Stockholder in exchange for 100%
     of the shares of Applied Epi International, Inc. and Applied Epi Europe,
     Inc., resulting in these entities becoming wholly owned subsidiaries of
     the Company.  Since Applied Epi International, Inc. and Applied Epi
     Europe, Inc. were under the common control of the Company due to the
     Majority Stockholder's controlling interest in all three entities, the
     transaction has been accounted for on an "as if pooling" basis.  The
     consolidated financial statements represent the financial position,
     results of operations, and cash flows of the Company, Applied Epi
     International, Inc., and Applied Epi Europe, Inc. for the period from
     January 1, 1999 to December 31, 2000 as if the transaction had occurred
     at the beginning of the earliest period presented.  All significant
     intercompany accounts and activities have been eliminated in these
     consolidated financial statements.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     MANAGEMENT'S USE OF ESTIMATES - The preparation of the consolidated
     financial statements in conformity with accounting principles generally
     accepted in the United States of America requires management to make
     estimates and assumptions that affect the reported amounts of assets and
     liabilities, disclosure of contingent assets and liabilities at the date of
     the consolidated financial statements, and the reported amounts of revenues
     and expenses during the reporting period. Actual results could differ from
     those estimates.



                                       9
<Page>



     BUSINESS RISKS - The nature of the Company's operations exposes the Company
     to certain business risks. The markets for the Company's products are
     competitive and subject to technological change and evolving industry
     standards that may significantly alter the operation of the Company and its
     potential customers. Also, the Company is dependent on certain key
     employees.

     CONCENTRATION OF CREDIT RISK - The Company had three and two different
     customers that accounted for 57% and 42% of consolidated trade accounts
     receivable at December 31, 2000 and 1999, respectively. The Company had
     sales to an unrelated international distributor of its products who
     individually accounted for 20% of consolidated sales in 2000. The Company
     had no customers who individually accounted for more than 10% of
     consolidated sales in 1999. During 2000 and 1999, the Company's top ten
     customers accounted for an aggregate of 67% and 46% of sales, respectively.

     The Company periodically reviews all customer accounts receivable for
     collectibility. It generally does not require collateral for its trade
     accounts receivable. The Company manages credit risk by evaluating
     creditworthiness regularly. Estimated losses within accounts receivable are
     reserved through establishment of an allowance for doubtful accounts.
     Customer accounts considered by management to be uncollectible are written
     off.

     FAIR VALUE OF FINANCIAL INSTRUMENTS - At December 31, 2000 and 1999, the
     Company's financial instruments included cash and cash equivalents,
     accounts receivable, accounts payable, and debt. At December 31, 2000 and
     1999, the fair values of cash and cash equivalents, accounts receivable,
     and accounts payable approximated carrying values because of the short-term
     nature of these instruments. The carrying amounts of the line of credit and
     long-term debt are considered to be representative of their respective fair
     values as their interest rates are generally based on market rates.

     FOREIGN CURRENCY TRANSLATION - Assets and liabilities of Applied Epi
     Europe, Inc. are translated from U.K. pounds to U.S. dollars at year-end
     rates, and the statements of operations are translated at average
     exchange rates during the year.  As the functional currency of Applied
     Epi Europe, Inc. is the U.S. dollar, all other translation adjustments
     are recorded in the consolidated statements of operations within other
     income (expense).  Foreign currency losses were $(264,480) and $(41,441)
     during 2000 and 1999, respectively.

     REVENUE RECOGNITION - The Company currently manufactures high-volume
     production, low-volume production, and research Molecular Beam Epitaxy
     (MBE) systems and performance products (effusions cells, software, and
     accessories). The Company's revenue recognition policies are in accordance
     with the Securities and Exchange Commission's (SEC) Staff Accounting
     Bulletin (SAB) No. 101, REVENUE RECOGNITION IN FINANCIAL STATEMENTS. The
     Company's revenue recognition policies for its products are as follows:

          High-Volume Production, Low-Volume Production, and Research Systems -
          For the majority of these systems, the customer is invoiced a portion
          of the contract price upon receipt of a signed purchase order (ranging
          from 0%-30%). Once the Company manufactures the system, the customer
          witnesses a factory acceptance test at the Company's facility and
          signs an acceptance form. The production system is then disassembled,
          shipped to the customer's site, and reassembled by the Company and
          customer personnel. Upon shipment, an additional portion of the
          contract price is billed to the customer (ranging from 50%-90%). Once
          the system has been reassembled at the customer's plant, generally a
          final site acceptance test is performed and the customer signs a final
          acceptance form. In some instances, final customer acceptance may also
          require achieving certain performance


                                       10

          specifications. Upon receipt of final customer acceptance, the
          remaining unbilled contract price is invoiced to the customer (ranging
          from 5%-20%) and all revenue from the contract is recognized. Until
          final customer acceptance has been received, amounts that have been
          billed to the customer net of the cost of systems awaiting final
          customer acceptance are recorded as deferred profit. At the time
          of final customer acceptance, a warranty reserve for the system is
          also established.

          Performance Products - Revenue is recognized upon shipment of product
          to the customer. Upon shipment, the customer is invoiced for the
          purchase price and payment is generally due within 30 days.

          Freight billed to customers is recorded in sales, and freight costs
          are included in cost of sales.

     CASH EQUIVALENTS - The Company considers all highly liquid investments
     purchased with a maturity of three months or less to be cash equivalents.

     INVENTORIES - Inventories are stated at the lower of cost (first-in,
     first-out method) or market. The Company includes in inventory all direct
     material, labor, and production costs.

     PROPERTY AND EQUIPMENT - Property and equipment are recorded at historical
     cost and are depreciated using both straight-line and accelerated methods
     over the following estimated useful lives:

     Building                                                         39 years
     Equipment, furniture, and fixtures                           5 - 10 years

     TAX INCREMENT FINANCING RECEIVABLE - On September 1, 1998, the Company
     entered into a development agreement with the Economic Development
     Authority of the Town of White Bear, Minnesota (the Authority) and
     Continental Technology Center, LLP (Continental). Under the terms of the
     agreement, the Authority was to pay Continental tax increment assistance on
     a pay-as-you-go basis commencing February 1, 2001. The Authority was to pay
     Continental 80% of the tax increments that it received and retained with
     respect to real estate taxes paid during the preceding calendar year. Such
     payments by the Authority were to continue until the earlier of (i)
     February 1, 2009 or (ii) until Continental had received the principal
     amount of $656,000, together with interest on the unpaid principal balance,
     at an annual rate of 9.75% (such interest to accrue from January 1, 1999).

     The Company leased approximately 90% of the building built by Continental
     from July 1998 until it purchased the building and adjacent land from
     Continental for $6,825,000 in December 1999. In connection with this
     purchase, the tax increment financing arrangement was assigned to the
     Company. In connection with this assignment, the Company recorded a
     receivable in the amount of the expected future payments to be received of
     $719,960 and reduced its basis in the building by that amount.

     GOODWILL - Goodwill of $1,301,583 is related to the 1995 acquisition of
     Superior Vacuum Technology, Inc. (SVT) and is shown in the balance sheets
     net of accumulated amortization of $715,870 and $585,712 at December 31,
     2000 and 1999, respectively. Goodwill is being amortized on a straight-line
     basis over ten years. The Company periodically reviews goodwill to assess
     recoverability. The Company evaluates the recoverability by measuring the
     unamortized balance of such goodwill against estimated future cash flows.
     If events or circumstances indicate


                                       11
<Page>

     that the carrying amount of such asset may not be recoverable, goodwill
     would be adjusted to the present value of the estimated future cash flows.
     Based on evaluations performed, there was no adjustment to the carrying
     value of goodwill during 2000 and 1999.

     IMPAIRMENT OF LONG-LIVED ASSETS - The Company evaluates its long-lived
     assets (including certain property and equipment) for impairment if events
     or changes in circumstances indicate that the carrying amount of such
     assets may not be recoverable. The Company evaluates the recoverability of
     long-lived assets by measuring the unamortized balance of the long-lived
     assets against estimated undiscounted future cash flows. If such analysis
     were to indicate that the carrying amount of such assets may not be
     recoverable, the assets would be adjusted to estimated fair value based on
     the present value of the estimated future cash flows. There was no
     adjustment to the carrying value of long-lived assets in 2000 and 1999.

     ACCRUED WARRANTY EXPENSES - The Company warrants its system and nonsystem
     products for periods of one and two years, respectively. The Company
     provides for estimated and known warranty costs through a warranty reserve.
     The warranty reserve of $298,332 and $146,881 at December 31, 2000 and
     1999, respectively, represents the Company's estimated liability for known
     and unknown defective items not yet repaired.

     RESEARCH AND DEVELOPMENT - The Company incurs costs related to research and
     development in connection with new product development and the enhancement
     of existing products. Research and development costs consist primarily of
     wages and related employee benefits and are charged to expense as incurred.

     STOCK-BASED COMPENSATION - The Company accounts for stock-based employee
     compensation arrangements in accordance with the provisions of Accounting
     Principles Board (APB) Opinion No. 25, ACCOUNTING FOR STOCK ISSUED TO
     EMPLOYEES. Accordingly, compensation expense has been recorded based on the
     intrinsic value amortized over the vesting period. In addition, the Company
     has adopted Financial Accounting Standards Board Interpretation No. (FIN)
     44, ACCOUNTING FOR CERTAIN TRANSACTIONS INVOLVING STOCK COMPENSATION - AN
     INTERPRETATION OF APB OPINION NO. 25.

     FIN 44 clarifies the application of APB Opinion No. 25 for only certain
     issues. Among other issues, FIN 44 clarifies (a) the definition of employee
     for purposes of applying APB Opinion No. 25, (b) the criteria for
     determining whether a plan qualifies as a noncompensatory plan, (c) the
     accounting consequence of various modifications to the terms of a
     previously fixed stock option or award, and (d) the accounting for an
     exchange of stock compensation awards in a business combination. FIN 44 had
     no effect on the Company's accounting policies concerning stock-based
     compensation.

     INCOME TAXES - Beginning with tax year 1997, the Company elected to be
     recognized as an S Corporation under the provisions of the Internal Revenue
     Code (the Code) and, as such, does not pay federal or state income taxes.
     The income from this corporation is included in the individual income tax
     returns of the stockholders, who are then responsible for the related
     income taxes.

     In 1997, Applied Epi Europe, Inc. also elected to be recognized as an S
     Corporation.  As discussed in Note 1, Applied Epi Europe, Inc. became a
     subsidiary of Applied Epi, Inc. in September 2000.  Applied Epi Europe,
     Inc. is currently a C Corporation.  As a result, Applied Epi Europe,
     Inc. will be required to pay approximately $1,000 in federal corporate
     income taxes for 2000.


                                       12
<Page>

     As an IC-DISC, Applied Epi International, Inc. is not required to pay
     federal corporate income taxes.  Approximately $465,000 and $838,000 of
     income from Applied Epi International, Inc. was not subject to income
     taxes in 2000 and 1999, respectively.  As required to retain its status
     as an IC-DISC, it is the intention of management to reinvest such
     earnings indefinitely.

     NEW ACCOUNTING STANDARD - On January 1, 2001, the Company adopted Statement
     of Financial Accounting Standards (SFAS) No. 133, ACCOUNTING FOR DERIVATIVE
     INSTRUMENTS AND HEDGING ACTIVITIES, as amended by SFAS No. 138, ACCOUNTING
     FOR CERTAIN DERIVATIVE INSTRUMENTS AND CERTAIN HEDGING ACTIVITIES. SFAS No.
     133 establishes accounting and reporting standards for derivative
     instruments and for hedging activities. It requires that all derivatives,
     including those embedded in other contracts, be recognized as either assets
     or liabilities and that those financial instruments be measured at fair
     value. The accounting for changes in the fair value of derivatives depends
     on their intended use and designation. Management has reviewed the
     requirements of SFAS No. 133 and has determined that they have no
     freestanding or embedded derivatives. All contracts that contain provisions
     meeting the definition of a derivative also meet the requirements of, and
     have been designated as, normal purchases or sales.

     RECLASSIFICATIONS - Certain reclassifications have been made to the 1999
     consolidated financial statements to conform with the 2000 presentation.
     These reclassifications had no effect on net income or total stockholders'
     equity as previously reported.

3.   SEGMENTS

     Management considers all of the Company's operating activities as one
     reportable segment due to commonality in products, production process,
     types or classes of customers, and method of product distribution.

     Sales by geographic area (allocated by the customer's location) were as
     follows for the years ended December 31:

5.   DEBT

      Short-term debt consists of the following at December 31:

                                                                2000        1999

     Line of credit                                          $3,000,000

     REVOLVING CREDIT AGREEMENT - In June 2000, the Company entered into a
     revolving credit agreement with U.S. Bank, National Association (the
     Revolver), which was amended in November 2000. The Revolver consists of a
     revolving loan of up to $5,000,000. The Revolver requires the Company to
     pay interest on the outstanding debt on a monthly basis at a floating rate
     equal to the sum of (a) the adjusted Eurodollar rate (as defined) plus the
     applicable margin (as defined). The Company's borrowing base under the
     Revolver is equal to the sum of (1) the lesser of 50% of eligible inventory
     or $3,000,000 plus (2) 80% of eligible receivables. The outstanding
     principal together with all unpaid interest is due on July 1, 2001. As of
     December 31, 2000, the outstanding balance under the Revolver was
     $3,000,000 and total available borrowing capacity was approximately
     $4,595,000.

     The credit agreement prohibits the Company from paying dividends or making
     any cash distributions on the Company's stock other than distributions to
     allow the Company's stockholders to pay their respective income taxes as a
     result of the Company's S Corporation status, without U.S. Bank's prior
     written consent.

     The Revolver is secured by substantially all of the Company's inventory,
     equipment, and general intangibles. The Revolver is guaranteed by the
     Majority Stockholder. Also, the Revolver requires the Company to meet
     certain affirmative and negative covenants. As of December 31, 2000, the
     Company was in compliance with the financial covenants contained in the
     Revolver.

      Long-term debt consists of the following at December 31:

     CREDIT AGREEMENTS - In December 1999, the Company entered into a credit
     agreement with Jackson National Life Insurance Company. The credit
     agreement consists of a $4,500,000 note payable over a term of 20 years.
     The note requires monthly payments of principal and interest of $39,081 at
     the greater of the annual LIBOR rate plus 2.05% or 6%. The proceeds of the
     note were used for the purchase of land and the Company's building in Saint
     Paul, Minnesota. The note is secured by a lien on the land and building and
     a security interest in certain property, fixtures, and equipment. The note
     is also guaranteed by the Majority Stockholder.

     In December 1999, the Company entered into a credit agreement with North
     American Banking Company (NABC). The agreement consists of a $600,000
     unsecured note, which is payable at maturity in December 2001. The note
     requires monthly interest payments at NABC's prime rate. The proceeds of
     the note were used for the purchase of land. The credit agreement requires
     the Company to maintain certain financial covenants as to minimum tangible
     net worth and current ratio. As of December 31, 2000, the Company was in
     compliance with the provisions of the financial covenants of the credit
     agreement.

     In July 2000, the Company entered into a term loan credit agreement with
     U.S. Bank (the Term Loan). The Term Loan consists of a $1,650,000 note
     payable beginning September 1, 2000. The Term Loan requires monthly
     payments of principal and interest of $12,694. The proceeds of the note
     were used for the purchase of land. The Term Loan is secured by
     substantially all of the Company's inventory, equipment, and general
     intangibles. The Term Loan is guaranteed by the Majority Stockholder.
     Interest on the outstanding debt is equal to a floating rate equal to the
     sum of the adjusted Eurodollar rate (as defined) plus 1.9%. The outstanding
     principal together with all unpaid interest is due on August 1, 2005.

     NOTES PAYABLE - RELATED PARTIES - In 1999, the Majority Stockholder
     advanced the Company $500,000. The note payable required monthly payments
     of interest only at prime plus 0.5%. In April 2000, the Company entered
     into a nonmonetary exchange whereby the note payable to the Majority
     Stockholder was offset against the amount due from NuVision LLC (see Note
     6). The difference of $89,932 was recorded as a nonmonetary stockholder
     distribution.

6.   RELATED-PARTY TRANSACTIONS AND AGREEMENTS

     DUE FROM RELATED PARTY - As of December 31, 1999, the Company was owed
     $589,932 by NuVision LLC. NuVision LLC and the Company have the same
     Majority Stockholder. The balance due was repaid in a nonmonetary exchange
     in April 2000 (see Note 5).

     NOTES RECEIVABLE AND STOCK RECEIVED FROM RELATED PARTY - During 1998 and
     until June 1999, the Company utilized its credit facility to advance funds
     to Spectracom, Inc. (Spectracom), which was majority-owned by the Company's
     Majority Stockholder. In June 1999, Spectracom was sold to an unrelated
     third party and all amounts due to the Company were repaid. The advances to
     Spectracom were at a favorable interest rate to Spectracom, for which
     Spectracom compensated


                                       15
<Page>

     the Company by issuing 3,070,880 shares of Spectracom's common stock to the
     Company. Management of the Company estimated that the fair value of the
     stock granted to the Company was approximately $3,137,000, of which
     $1,605,000 was recorded as interest income in 1998 with the remaining
     amount of $1,532,000 reflected in the December 31, 1998 balance sheet as
     discount on notes receivable from related party. Upon receipt of the
     Spectracom stock, the Company distributed the Spectracom stock to the
     Company's stockholders. This discount was recorded as interest income
     ratably by the Company until June 1999, when the remaining discount was
     recognized as interest income when Spectracom was sold and repaid all
     amounts owed to the Company.

     MAJORITY STOCKHOLDER SALES OF COMMON STOCK - In April 2000, the Majority
     Stockholder sold 711,390 common shares of the Company to four current
     employees at $1.12 per share. This transaction has been accounted for in
     accordance with the AICPA's Accounting Interpretation No. 1 of APB Opinion
     No. 25. Accordingly, a charge to compensation expense was made to the
     extent the price was below the fair value of the shares sold and a

7.   STOCK OPTION PLANS AND STOCK-BASED COMPENSATION

     STOCK OPTION PLANS - In June 1993, the Board approved the 1993 Stock Option
     Plan under which the Company has reserved 7,500,000 shares of common stock
     for the issuance of incentive stock options (ISO) and nonqualified stock
     options (NQO) to officers and other key employees. In July 2000, the Board
     approved the 2000 Stock Plan under which the Company has reserved 7,500,000
     shares of common stock for the issuance of ISOs, NQOs, and restricted stock
     to executives, key employees, consultants, and directors. The provisions of
     the plans, as amended, state that the term of any ISO shall be fixed by the
     Board. However, no ISO shall be exercisable more than ten years after the
     date of grant. The term of any ISO granted to an employee who owns more
     than 10% of the combined voting power of all classes of stock of the
     Company is limited to no more than five years from the date of grant.

     For employees who do not own more than 10% of the combined voting power of
     all classes of stock of the Company, the ISO exercise price shall not be
     less than fair value at the date of grant. For employees who own more than
     10% of the combined voting power of all classes of stock of the Company,
     the ISO exercise price shall not be less than 110% of the fair value at the
     date of grant. The NQO exercise price per share is any price deemed
     appropriate by the Board.

     Options on common shares granted and outstanding, as well as the weighted
     average exercise price, are shown below:

</Table>

     As of December 31, 2000, there were 5,079,690 and 7,142,505 shares
     available for grant under the 1993 Stock Option Plan and 2000 Stock Plan,
     respectively.

     STOCK-BASED COMPENSATION - Stock options granted during 2000 contained
     exercise prices that were management's best estimate of fair value of the
     underlying common stock on the date of grant. However, subsequent to the
     grant date, management concluded that certain grants, which occurred after
     the Company's development of a new high-volume MBE system, may not have
     fully reflected the impact of this event. Management has concluded that for
     the grants made in April and May 2000, the fair value per share on the date
     of grant was $8.84. For subsequent grants, management has concluded that
     the fair value per share was $10.00. During 2000, compensation cost
     aggregated $12,403,082, which will be amortized to expense over the
     three-year vesting period of the options. This compensation is being
     recognized on an accelerated basis using the model presented in paragraph
     24 of FIN 28. Accordingly, amortization of these options, which vest over
     three years, will be approximately 48%, 37%, and 15%, respectively.
     However, in August 2000, vesting was accelerated on 1,124,310 options
     originally issued in April 2000 to two officers of the Company. This
     accelerated vesting resulted in a new measurement date and a noncash charge
     of $8,684,170. For the year ended December 31, 2000, compensation expense
     related to these grants aggregated $10,210,151.

     PRO FORMA DISCLOSURES - As described in Note 2, the Company uses the
     intrinsic value method to measure compensation expense associated with
     grants of stock options to employees. If the Company had used the fair
     value method to measure compensation, the Company's pro forma net loss
     would have been approximately $19,200,000 for the year ended December 31,
     2000.

     The fair value of each option grant was estimated on the grant date using
     the Black-Scholes option pricing model with the following weighted average
     assumptions during the year ended December 31, 2000:

<Table>
                                                                   
     Expected life of option grants                                   3 years
     Risk-free interest rate                                             6.0%
     Volatility                                                          0.0%
     Dividend yield                                                      0.0%
</Table>

     The Black-Scholes option pricing model was designed to value readily
     tradable stock options with relatively short lives. However, management
     believes that the assumptions used to value the options and the model
     applied yield a reasonable estimate of the fair value of the grants made
     under the circumstances.

8.   EMPLOYEE PERFORMANCE PLAN

     The Company had a nonqualified employee performance plan (the Plan). The
     Plan provided for an annual discretionary award of performance units
     determined by the Board. The value per unit was determined at the end of
     the current year based on cumulative adjusted net income, as defined, for
     the three-year period then ended. The Company recognized expense for units
     granted in the current year and the change in the value of the unpaid units
     granted in prior years. Units exercised in a given year were paid in cash
     at the value per unit determined on the last calendar year-end. The Company
     expensed approximately $16,000 and $468,500 related to the Plan during 2000
     and 1999, respectively. During 2000 and 1999, the Company paid $22,648 and
     $104,305 to participants who redeemed 5,662 and 34,538 units, respectively.
     Prior to the Plan's termination, the value of a performance unit as of
     December 31, 2000 was $0.772.

     As of December 31, 2000, the Plan was terminated by the Board. In
     connection with the termination of the Plan, the Company approved a plan to
     grant options to purchase shares of the Company's restricted common stock
     in exchange for the performance units.

     In exchange for the employees' (the Optionees) performance units in and all
     rights under the Plan, including all rights to receive cash under the Plan,
     the Company granted options on January 1, 2001 to the Optionees to purchase
     shares of restricted common stock. Each option received in exchange for a
     performance unit has an exercise price of $0.05 per share and was 100%
     vested upon grant. Upon exercise of the option, the Optionees shall receive
     shares of the Company's restricted common stock. The Optionees agree that
     the shares of restricted stock shall not be sold, exchanged, transferred,
     pledged, hypothecated, or otherwise disposed of until the earlier of the
     following: (1) six months after the consummation of a firm commitment,
     underwritten initial public offering of the Company's common stock; or (2)
     a sale of the Company (as defined). However, a one-time exception allowed
     Optionees to sell their stock to the Company for cash on March 15, 2001.
     Certain employees exercised options for 83,440 shares of common stock and
     subsequently sold those shares to the Company at the Plan's termination
     value. The difference between the termination value of a performance unit
     and the exercise price of the options for these employees aggregated
     $60,243. This amount is recorded as a current liability at December 31,
     2000.

     In connection with the termination of the Plan, the Company recorded
     additional paid-in capital of $6,393,713 representing the value of the
     1,655,400 options issued on January 1, 2001 to those employees not electing
     the one-time exception described above. The options issued in connection
     with the termination of the Plan are not included in the tables in Note 7.
     The Company recorded $5,198,514 of stock-based compensation in connection
     with the termination of the Plan based upon an independent third-party
     valuation.

9.   401(k) PLAN

     The Company adopted a 401(k) plan effective April 1995. Employees become
     eligible to participate in the 401(k) plan after their first month of
     employment. The 401(k) plan is intended to qualify under Section 401(k) of
     the Code, so that contributions to the 401(k) plan by employees or the
     Company and the investment earnings thereon are not taxable to the
     employees until withdrawn. If the 401(k) plan qualifies under Section
     401(k) of the Code, the Company's contributions will be deductible when
     made. Employees may elect to reduce their current


                                       18
<Page>

     compensation by up to the statutorily prescribed annual limit of $10,500 in
     2000 and to have those funds contributed to the 401(k) plan. The 401(k)
     plan permits, but does not require, the Company to make additional matching
     contributions on behalf of all participants. During 2000 and 1999, the
     Company did not make any contributions to the 401(k) plan.

10.  COMMITMENTS AND CONTINGENCIES

     LEASES - In 1998, the Company entered into an operating lease for its
     facility. In December 1999, the Company purchased its facility and an
     adjacent lot for $6,825,000 and canceled the operating lease. Rent expense
     prior to the lease cancellation totaled approximately $582,000 for the year
     ended December 31, 1999.

     PURCHASE COMMITMENT - At December 31, 2000, the Company had a contract with
     Kalway Construction Company for approximately $2,193,000 for construction
     of a new building adjacent to its Saint Paul, Minnesota facility. At
     December 31, 2000, approximately $842,000 of the contract had been paid.
     Such construction-in-progress is included in buildings on the balance
     sheet.

     LITIGATION - In the ordinary course of business, the Company is subject to
     various lawsuits, claims, and proceedings relating to the conduct of its
     businesses. The Company records liabilities when loss amounts are
     determined to be probable and reasonably estimable. Although the outcome of
     litigation cannot be predicted with certainty and some lawsuits, claims, or
     proceedings may be disposed of unfavorably to the Company, management
     believes, based on facts presently known, that the outcome of such legal
     proceedings and claims will not have a material adverse effect on the
     Company's financial position, liquidity, or future results of operations.

11.  SUBSEQUENT EVENTS

     SUBORDINATED NOTES - In February 2001, the Company issued $5,000,000 of a
     $10,000,000 commitment in subordinated notes to certain officers,
     directors, and stockholders of the Company. Interest at 10% per annum is
     payable semiannually in arrears, and the entire outstanding principal
     balance is due in February 2004. Subject to certain restrictions, the notes
     can be prepaid at any time in increments of $500,000 with the following
     penalties:

     Months                                           Penalty

     1 - 12                               5% fee on the amount of the prepayment
     13 - 24                              4% fee on the amount of the prepayment
     Over 24                              No prepayment penalty

     The notes are required to be prepaid without penalty upon an initial public
     offering (as defined), a change in control (as defined), or an event of
     default (as defined). The notes are unsecured and subordinated to all of
     the Company's existing and future indebtedness.

     In exchange for the $10,000,000 commitment in subordinated notes, the
     Company issued detachable warrants to purchase 1,150,000 shares of common
     stock. The warrants have an exercise price of $5.40 per share, contain
     certain antidilution provisions, and have a term of five years. The
     warrants were valued at approximately $1,088,000 based on the Black-Scholes
     option pricing model and will be accounted for as additional paid-in
     capital. The resulting discount on


                                       19
<Page>

     the subordinated notes will be amortized as additional interest expense
     over the term of the debt using the effective interest method.

     MERGER - On September 6, 2001, Veeco Instruments Inc. (Veeco) entered into
     an Agreement and Plan of Merger, (the Merger Agreement), by and among the
     Company, Veeco Acquisition Corp. (Acquisition), Veeco, and certain
     stockholders of the Company. On September 17, 2001, pursuant to the Merger
     Agreement, Acquisition merged with and into the Company. As a result, the
     Company became a wholly owned subsidiary of Veeco. Under the Merger
     Agreement, the stockholders of the Company received an aggregate of
     3,883,460 shares of Veeco common stock and $29.8 million in cash. In
     addition, Veeco incurred acquisition costs and exchanged and assumed
     options and warrants of Applied Epi for options and warrants to purchase
     1,021,248 shares of the Veeco's common stock. The assumed options and
     warrants were recorded at fair market value using the Black-Scholes
     option-pricing model. The merger will be accounted for using the
     purchase method of accounting.

NOTE 3 -- SUBORDINATED NOTES

In February 2001, the Company issued $5.0 million of a $10.0 million commitment
in subordinated notes to certain officers, directors, and stockholders of the
Company. Interest at 10% per annum is payable semiannually in arrears, and the
entire outstanding principal balance is due in February 2004. Subject to certain
restrictions, the notes can be prepaid at any time in increments of $500,000
with the following penalties:

     Months                                           Penalty

     1 - 12                               5% fee on the amount of the prepayment
     13 - 24                              4% fee on the amount of the prepayment
     Over 24                              No prepayment penalty

The notes are required to be prepaid without penalty upon an initial public
offering (as defined), a change in control (as defined), or an event of default
(as defined). The notes are unsecured and subordinated to all of the Company's
existing and future indebtedness.


                                       24
<Page>

In exchange for the $10.0 million commitment in subordinated notes, the Company
issued detachable warrants to purchase 1,150,000 shares of common stock. The
warrants have an exercise price of $5.40 per share, contain certain antidilution
provisions, and have a term of five years. The warrants were valued at
approximately $1,088,000 based on the Black-Scholes option pricing model and
were accounted for as additional paid-in capital. The resulting discount on the
subordinated notes is amortized as additional interest expense over the term of
the debt using the effective interest method.

NOTE 4 - RECENT ACCOUNTING PRONOUNCEMENTS

In June 2001, the FASB issued SFAS No. 141, BUSINESS COMBINATIONS, and SFAS No.
142, GOODWILL AND OTHER INTANGIBLE ASSETS, effective for fiscal years beginning
after December 15, 2001. Under the new rules, goodwill and other intangible
assets deemed to have indefinite lives will no longer be amortized but will be
subject to annual impairment tests in accordance with the Statements. Other
intangible assets will continue to be amortized over their useful lives. In
addition, Statement 141 eliminates the pooling-of-interests method of accounting
for business combinations, except for qualifying business combinations that were
initiated prior to July 1, 2001.

The Company will apply the new rules on accounting for goodwill and other
intangible assets beginning in the first quarter of 2002. During 2002, the
Company will perform the first of the required impairment tests of goodwill and
other intangible assets as of January 1, 2002. As of June 30, 2001, the Company
has not yet determined what the effect these standards will have on the earnings
or financial position of the Company.

NOTE 5 - COMMITMENTS AND CONTINGENCIES

PURCHASE COMMITMENT

At December 31, 2000, the Company had a contract with Kalway Construction
Company for approximately $2.2 million for construction of a new building
adjacent to its Saint Paul, Minnesota facility. During February 2001, the
construction of the new building was completed and the contract was paid in
full.

NOTE 6 - SUBSEQUENT EVENT

On September 6, 2001, Veeco Instruments Inc. (Veeco) entered into an Agreement
and Plan of Merger, (the Merger Agreement), by and among the Company, Veeco
Acquisition Corp. (Acquisition), Veeco, and certain stockholders of the Company.
On September 17, 2001, pursuant to the Merger Agreement, Acquisition merged with
and into the Company. As a result, the Company became a wholly owned subsidiary
of Veeco. Under the Merger Agreement, the stockholders of the Company received
an aggregate of 3,883,460 shares of Veeco common stock and $29.8 million in
cash. In addition, Veeco incurred acquisition costs and exchanged and assumed
options and warrants of Applied Epi for options and warrants to purchase
1,021,248 shares of the Veeco's common stock. The assumed options and warrants
were recorded at fair market value using the Black-Scholes option-pricing model.
The merger consideration was determined by arm's-length negotiations among the
respective parties. The merger will be accounted for using the purchase method
of accounting. In connection with the merger, the subordinated notes, which are
required to be prepaid without penalty upon a change in control, will be repaid.

UNAUDITED PRO FORMA COMBINED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

The following unaudited pro forma combined condensed consolidated financial
statements are presented to give effect to the purchase agreement and the
acquisition of Applied Epi, Inc. (Applied Epi) under the purchase method of
accounting. The balance sheet assumes that the Applied Epi acquisition had been
consummated on June 30, 2001. The statements of operations for the year ended
December 31, 2000 and for the six months ended June 30, 2000 and 2001, assume
that the acquisition of Applied Epi had been consummated on January 1, 2000. The
pro forma financial statements are not necessarily indicative of the results of
operations or the financial position which would have occurred had the Applied
Epi acquisition been consummated at such times, nor are they necessarily
indicative of the results of future results of operations or financial position.
The allocation of the purchase price of Applied Epi has been determined by an
independent appraisal and reflects the fair value of any adjustments to assets
and liabilities. The unaudited pro forma combined condensed consolidated
financial statements should be read in conjunction with the historical condensed
consolidated financial statements of Veeco Instruments Inc., and Subsidiaries
("Veeco" or "the Company") including notes thereto, and the financial statements
of Applied Epi, Inc., included herein, including the notes thereto.

PRO FORMA COMBINED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 -- PRO FORMA BALANCE SHEET ADJUSTMENTS

On September 17, 2001, Veeco acquired Applied Epi in a business combination
accounted for as a purchase. Under the merger agreement, the stockholders of
Applied Epi received an aggregate of 3,883,460 shares of Veeco common stock and
$29.8 million in cash. In addition, Veeco incurred acquisition costs and
exchanged and assumed options and warrants of Applied Epi for options and
warrants to purchase 1,021,248 shares of Veeco's common stock. The assumed
options and warrants were recorded at fair market value using the Black-Scholes
option-pricing model. The following notes explain the pro forma adjustments:

      (a)   Adjustment to record the $29.8 million cash payment to the
            stockholders' of Applied Epi and the repayment of Applied Epi's
            subordinated debt of $5.0 million.

      (b)   Adjustment to record a $3.4 million increase to accounts receivable,
            to conform Applied Epi's treatment of customer deposits to Veeco's
            methodology. This has no effect on the statement of operations.

      (c)   Adjustment to record a $1.5 million step-up in the fair value of
            inventory.

      (d)   Adjustment to record a deferred tax asset of $2.3 million and a
            $22.7 million deferred tax liability to reflect the difference
            between the book and tax basis of Applied Epi's net assets. Prior to
            the merger, Applied Epi was an S Corporation and did not provide
            deferred taxes at the corporation level. In addition, a significant
            portion of the deferred tax liability results from the step up in
            basis of assets, associated with the merger being accounted for
            using the purchase method.

      (e)   Adjustment to record $101.6 million of the excess purchase price
            over the net assets acquired in connection with Veeco's purchase of
            Applied Epi and $55.5 million of other intangible assets acquired
            through the acquisition of Applied Epi, off-set by a $7.0 million
            write-off of purchased in-process technology.

      (f)   Adjustment to record acquisition costs of $2.9 million and to
            reclass customer deposits of $2.8 million, in connection with
            adjustment (b).

      (g)   Adjustment to record the decrease of $3.5 million in deferred gross
            profit to recognize the fair value of the liability assumed.

      (h)   Adjustment to record the elimination of the historical equity of
            Applied Epi including $27.0 million shares of common stock,
            $26.0 million of additional paid-in-capital, $11.4 million of
            retained deficit and $1.5 million of deferred stock-based
            compensation. In addition, this adjustment also records the
            fair market value of the shares, options and warrants issued
            in the merger with Applied Epi aggregating $120.3 million.

NOTE 2 - PRO FORMA STATEMENTS OF OPERATIONS ADJUSTMENTS

Details of the pro forma adjustments relating to the acquisition and financing
are set forth below:

      (i)   Adjustment to record the amortization expense related to the
            amortizable intangible assets acquired. The intangible assets
            acquired are comprised of the following: $41.0 million of core


                                       31

            technology, amortized over approximately six years; $1.0 million of
            non-compete agreements, amortized over three years; $4.5 million of
            customer related intangibles, amortized principally over six months
            and $2.0 million of trademarks and trade names, amortized over ten
            years.

      (j)   Adjustment to record the reduction of interest income, due to the
            use of $32.7 million of cash related to the purchase of Applied Epi.

      (k)   Adjustment to record an income tax provision (benefit) for Applied
            Epi and pro forma adjustments using a 35% tax rate. Prior to
            the merger, Applied Epi was an S Corporation and was not taxed
            at the Corporation level.

The pro forma adjustments included in the income statements do not give effect
to the impact on gross profit of the adjustment to increase inventory by
approximately $1.5 million to its estimated fair value. The pro forma
adjustments also do not give effect to the impact on sales and gross profit of
the adjustment to decrease deferred gross profit by approximately $3.5 million
to its estimated fair value. Such adjustments, as of the June 30, 2001 balance
sheet, were required under the purchase method of accounting.
