Dear Stockholders of MKS Instruments, Inc.:

     I am writing to you today about MKS Instruments, Inc.'s proposed
acquisition of the ENI business of Emerson Electric Co.

     In connection with the acquisition, MKS will issue to Emerson an aggregate
of 12,000,000 shares of MKS common stock. Upon completion of the acquisition, we
expect that Emerson and its subsidiaries will own approximately 24% of the
outstanding common stock of MKS. Additionally, Emerson will enter into a
shareholder agreement which regulates its purchase and sale of MKS common stock
and provides for the appointment of James G. Berges, President of Emerson, to
the MKS Board of Directors. MKS common stock is traded on the Nasdaq National
Market under the trading symbol "MKSI" and closed at a price of $     per share
on December   , 2001.

     We cannot complete the acquisition unless the stockholders of MKS approve
the issuance of MKS common stock to Emerson in connection with the acquisition.
THE BOARD OF DIRECTORS OF MKS HAS UNANIMOUSLY APPROVED THE ACQUISITION AND
RECOMMENDS THAT YOU APPROVE THE ISSUANCE OF MKS COMMON STOCK IN CONNECTION WITH
THE ACQUISITION. Please refer to the opinion of MKS' financial advisor Merrill
Lynch, which is attached as Annex B hereto.

     The accompanying proxy statement provides detailed information about MKS,
Emerson, the ENI business and the acquisition. Please give all of this
information your careful attention.

     Your vote is very important regardless of the number of shares you own. To
vote your shares, you may use the enclosed proxy card or attend the special
meeting. To approve the proposal submitted to you, you must vote "FOR" the
proposal by following the instructions stated on the enclosed proxy card.

                                          Sincerely,

                                          JOHN R. BERTUCCI
                                          Chairman and Chief Executive Officer

     At the meeting, you will consider and vote on a proposal to approve the
issuance of MKS common stock to Emerson Electric Co. or its subsidiaries in
connection with the acquisition of the ENI business of Emerson. Under the terms
of the agreement and plan of merger between MKS and Emerson dated October 30,
2001, which we also refer to as the acquisition agreement, MKS will, subject to
MKS stockholder approval, issue an aggregate of 12,000,000 shares of MKS common
stock.

     We will transact no other business at the special meeting, except business
which may be properly brought before the special meeting or any adjournment or
postponement of the special meeting.

     Only the holders of record of shares of MKS common stock at the close of
business on Wednesday, November 14, 2001, the record date for the special
meeting, are entitled to notice of, and to vote at, the special meeting and any
adjournment or postponement of the special meeting.

     The enclosed proxy statement describes the agreement and plan of merger and

Q:  WHEN DO YOU EXPECT TO COMPLETE THE ACQUISITION OF THE ENI BUSINESS?

A:  We expect to complete the acquisition by the end of January, 2002, but
    neither MKS nor Emerson can predict the exact timing of the closing.

Q:  WHO MUST APPROVE THE ACQUISITION?

A:  In addition to the approvals of the board of directors of MKS and Emerson,
    which have already been obtained, MKS stockholders must approve the issuance
    of MKS common stock in connection with the acquisition.

Q:  WHAT VOTE OF MKS STOCKHOLDERS IS REQUIRED TO APPROVE THE ISSUANCE OF MKS
    COMMON STOCK IN THE ACQUISITION?

A:  The affirmative vote of the holders of at least a majority of the shares of
    MKS common stock present or represented by proxy at the MKS special meeting
    is required to approve the issuance of MKS common stock in connection with
    the acquisition. John R. Bertucci, MKS' chairman and chief executive
    officer, together with members of Mr. Bertucci's family and trusts for the
    benefit of Mr. and Mrs. Bertucci and their immediate family, who
    beneficially own 39.54% of all outstanding shares of MKS common stock as of
    November 14, 2001, the record date of the special meeting, have agreed to
    vote in favor of the issuance of the MKS common stock in connection with the

    attend the MKS stockholder meeting and vote in person instead of submitting

    fail to indicate your vote on your proxy, your proxy will be counted as a
    vote in favor of the issuance of MKS common stock in connection with the
    acquisition, unless your shares are held in a brokerage account.

Q:  IF MY SHARES ARE HELD IN A BROKERAGE ACCOUNT, WILL MY BROKER VOTE MY SHARES
    FOR ME?

A:  Your broker cannot vote your shares on the proposal relating to the issuance
    of MKS shares in connection with the acquisition without instructions from
    you on how to vote. Therefore, it is important that you follow the
    directions provided by your broker regarding how to instruct your broker to
    vote your shares.

Q:  MAY I CHANGE MY VOTE AFTER I HAVE MAILED IN MY SIGNED PROXY CARD?

A:  Yes. You may change your vote at any time before the vote takes place at the
    stockholder meeting. To change your vote, you may either submit a later

    authorizing you to vote your shares.

Q:  WHERE AND WHEN IS THE MKS STOCKHOLDER MEETING?

A:  The special meeting of MKS stockholders will be held at 10:00 a.m., local
    time, on [Monday, January 7, 2002,] at Hale and Dorr LLP, 60 State Street,
    Boston, Massachusetts 02109.

                                 THE COMPANIES

MKS INSTRUMENTS, INC.

     MKS Instruments, Inc., commonly known as MKS, is a leading worldwide
developer, manufacturer and supplier of instruments, components and subsystems
used to measure, control, and analyze gases in semiconductor manufacturing and
similar industrial manufacturing processes and a leading developer, manufacturer
and supplier of reactive gas generation and power delivery products. MKS sold
products to more than 4,000 customers in 2000. In addition to semiconductors,
MKS' products are used in processes to manufacture a diverse range of products,
such as optical filters, fiber optic cables, flat panel displays, otherwise
known as FPDs, magnetic and optical storage media, medical equipment,
architectural glass, solar panels and gas lasers.

ENI BUSINESS

     The ENI business designs, manufactures, sells and supports high precision,
high power electrical conversion and control systems in the United States,
Europe and Asia. These systems are primarily used in thin film processing
equipment in the global semiconductor, data storage, FPD, and industrial
coatings markets. These products are integrated into the manufacturing tools of
these industries to produce finished goods which include semiconductor
integrated circuits, computer hard disks, FPDs, compact discs and digital video
discs. The ENI business' products and systems refine, modify and control the raw
electrical power generated by a utility and convert it into reliable solid state
power that can be readily used by production tools for advanced thin film
processing applications. See "The ENI Business" on page 44.

                                THE ACQUISITION
                                   (PAGE 19)

     In this transaction, MKS will acquire (through the acquisition of capital
stock and certain assets) the assets, properties and business of the ENI
business. The acquisition will have three components which will all occur
simultaneously. First, a subsidiary of MKS, Navigator Acquisition Corp., will be
merged with and into ENI Technology, Inc. ENI Technology, Inc. will survive the
merger as a wholly-owned subsidiary of MKS. Second, subsidiaries of MKS will
acquire certain of the assets and assume certain of the liabilities of ENI Japan
Ltd. and Astec Germany GmbH. Third, a subsidiary of MKS will purchase all of the
outstanding capital stock of ENI Hong Kong which, prior to the closing of the
acquisition, will be the parent of ENI Taiwan and ENI China. As a result of
these transactions, Emerson, or its subsidiaries, shall receive 12,000,000
shares of MKS common stock, which we collectively refer to herein as the
"acquisition consideration." The agreement and plan of merger governing the
acquisition is attached to this proxy statement as Annex A. We encourage you to
read the acquisition agreement.

                                   (PAGE 16)

     The affirmative vote of the holders of at least a majority of the shares of
MKS common stock present or represented by proxy at the MKS special meeting of
stockholders is required to approve the issuance of MKS common stock in

     - MKS stockholders approving the issuance of the shares of MKS common stock
       in connection with the acquisition;

     - the MKS and Emerson representations and warranties set forth in the
       acquisition agreement must be true and correct as of the date of the
       acquisition agreement and closing, or other date where applicable, other
       than such failures to be true and correct that could not reasonably be
       expected to have, individually or in the aggregate, a material adverse
       effect on the MKS or the ENI business, which ever is applicable;

     - the expiration or termination of all applicable waiting periods under the
       Hart-Scott-Rodino Act and applicable foreign anti-trust laws;

     - the absence of any applicable law or regulation, and any judgment,
       injunction, order or decree prohibiting the consummation of the
       acquisition;

     - no material adverse effect on the business, financial condition or
       results of operation of either the ENI business or MKS shall have
       occurred since October 1, 2001;

       agreement;

     - Emerson shall have completed the reorganization of the ENI business; and

                                   (PAGE 34)

     MKS has agreed that neither it nor any of its subsidiaries will solicit,
initiate, encourage or take any other action to facilitate the making of any
acquisition proposal, enter into, continue or otherwise participate in any
discussions or negotiations regarding an acquisition proposal, or furnish
information or cooperate with any person with respect to an acquisition
proposal.

                    TERMINATION OF THE ACQUISITION AGREEMENT
                                   (PAGE 40)

     MKS and Emerson can mutually agree to terminate the acquisition agreement
without completing the acquisition, and either MKS or Emerson can terminate the
acquisition agreement if any of the following occur:

     - Both MKS and Emerson may terminate the acquisition agreement:

       - by mutual written consent;

       - by giving written notice to the other party if the closing has not
         occurred on or before June 30, 2002 by reason of the failure of any
         condition precedent to the terminating party's closing of the
         acquisition, unless the failure results primarily from a breach by the
         terminating party of any representation, warranty or covenant contained
         in the acquisition agreement; or

       - by giving written notice to the other party at any time after MKS'
         stockholders have voted on, and failed to approve, the issuance of the
         MKS common stock in connection with the acquisition.

     - MKS may terminate the acquisition agreement if:

       - Emerson is in breach of any representation, warranty or covenant
         contained in the acquisition agreement, which breach causes Emerson to
         be unable to "bring down" the representations, warranties and covenants
         at closing, and such breach is not remedied within 20 days of delivery
         of written notice of the breach; or

       - prior to the stockholder vote to approve issuance of MKS common stock
         in connection with the acquisition, the MKS board of directors
         withdraws its recommendation to approve issuance of MKS common stock,
         as permitted by the acquisition agreement.

     - Emerson may terminate the acquisition agreement if:

       - MKS is in breach of any representation, warranty or covenant contained
         in the acquisition agreement, which breach causes MKS to be unable to
         "bring down" the representations, warranties and covenants at closing,
         and such breach is not remedied within 20 days of delivery of written
         notice of the breach;

       - MKS' board of directors withdraws or modifies, or proposes to withdraw
         or modify in a manner adverse to Emerson, its recommendation to approve
         the issuance of the MKS common stock in connection with the
         acquisition; or

       - MKS breaches the "non-solicit" covenant in the acquisition agreement
         and an acquisition proposal is announced by a party other than Emerson,
         or any of its affiliates or representatives.

                         TERMINATION FEES AND EXPENSES
                                   (PAGE 40)

     MKS and Emerson, generally, will bear their own expenses related to the
acquisition. However, under some circumstances set forth in the acquisition
agreement, MKS may be required to pay Emerson a termination fee of $7,000,000
and reimburse Emerson up to a maximum of $500,000 for out of pocket expenses
related to the acquisition.

                              ACCOUNTING TREATMENT
                                   (PAGE 28)

     In accordance with recently issued Statement of Financial Accounting
Standards No. 141, "Business Combinations," and Statement of Financial
Accounting Standards No. 142, "Goodwill and Other Intangible Assets," MKS will
use the purchase method of accounting for a business combination to account for
the acquisition, as well as the new accounting and reporting regulations for
goodwill and other
                                        7


intangibles. Under these methods of accounting, the assets and liabilities of
the ENI business, including all intangible assets, will be recorded at their
respective fair values. All intangible assets will be amortized over their
estimated useful lives with the exception of goodwill and any other intangibles
with indefinite lives. The financial position, results of operations and cash
flows of the ENI business will be included in MKS' financial statements
prospectively as of the completion of the acquisition.

                       OPINION OF MKS' FINANCIAL ADVISOR
                                   (PAGE 20)

     Merrill Lynch, Pierce, Fenner & Smith Incorporated provided a fairness
opinion to the board of directors of MKS on October 30, 2001 that, as of the
date of such opinion, the aggregate consideration payable under the acquisition
agreement was fair, from a financial point of view, to the holders of shares of
MKS' common stock. The full text of the opinion, which sets forth assumptions
made, matters considered and limitations on the review undertaken in connection
with the opinion, is attached to this proxy statement as Annex B and is
incorporated in this proxy statement by reference. The opinion of Merrill Lynch
does not constitute a recommendation as to how any stockholder should vote with
respect to the issuance of MKS common stock in connection with the acquisition.
Holders of shares of MKS common stock are urged to, and should, read the opinion
carefully and in its entirety.

     The board of directors of MKS retained Merrill Lynch to assist it in its
evaluation of the proposed acquisition. MKS has agreed to reimburse Merrill
Lynch for all reasonable fees and disbursements of its counsel and all of its
reasonable travel and other out-of-pocket expenses arising in connection with
its engagement, and to indemnify Merrill Lynch and its affiliates to the full
extent permitted by law against liabilities relating to or arising out of its
engagement, except for liabilities found to have resulted from the bad faith,
willful misconduct or gross negligence of Merrill Lynch.

            MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS
                                   (PAGE 29)

     There will be no United States federal income tax consequences to the
holders of MKS common stock as a result of the completion of the acquisition.

           CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING STATEMENTS

     MKS believes this proxy statement and the documents that it incorporates by
reference herein contain "forward-looking statements" within the meaning of the
Private Securities Litigation Reform Act of 1995. These statements are subject
to risks and uncertainties and are based on the beliefs and assumptions of
management of MKS, based on information currently available to MKS' management.
When we use words such as "believes," "expects," "anticipates," "intends,"
"plans," "estimates," "should," "likely" or similar expressions, we are making
forward-looking statements. Forward-looking statements include the information
concerning possible or assumed future results of operations of MKS and benefits
of the acquisition of the ENI business set forth under:

     - "Summary,"

     - "Selected Unaudited Pro Forma Combined Consolidated Financial
       Information,"

     - "The Acquisition -- MKS' Reasons for the Acquisition,"

     - "The Acquisition -- Recommendations of MKS' Board of Directors," and

     - "Management's Discussion and Analysis of Financial Condition and Results
       of Operations of the ENI Business."

     Forward-looking statements also include the information concerning possible
or assumed future results of operations of MKS under "Business" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" in MKS' Annual Report on Form 10-K, Quarterly Reports on Form 10-Q,
and Current Reports on Form 8-K, that we incorporate by reference into this
proxy statement.

     Forward-looking statements are not guarantees of performance. They involve
risks, uncertainties and assumptions. The future results and stockholder values
of MKS may differ materially from those expressed in the forward-looking
statements. Many of the important factors that will determine these results and
values are beyond our ability to control or predict. These factors include the
following:

     - the risk that if the acquisition's anticipated benefits do not meet the
       expectations of financial or industry analysts, the market price of MKS
       common stock may decline;

     - the risk that the failure to complete the acquisition may result in MKS
       paying termination fees to Emerson and cause MKS to nevertheless incur
       legal, financial advisory and accounting fees, all of which may dilute
       the value of MKS' stock and decrease its market price;

     - the risk that the acquisition may cause the ENI business to lose key
       personnel which could materially affect its business and require the ENI
       business to incur substantial costs to recruit replacements for lost
       personnel; and

     - the risk that customers of MKS and the ENI business may terminate their
       relationship with MKS or the ENI business as a result of concerns over
       products and services to be provided following the acquisition.

     You are cautioned not to put undue reliance on any forward-looking
statements. For those statements, MKS claims the protection of the safe harbor
for forward-looking statements contained in the Private Securities Litigation
Reform Act of 1995. Except as otherwise required by law, MKS is under no duty to
update any of these forward-looking statements after the date of this proxy
statement.

             SELECTED HISTORICAL CONSOLIDATED FINANCIAL DATA OF MKS

     The following table presents selected historical consolidated financial
data of MKS. On January 26, 2001, MKS merged with Applied Science and
Technology, Inc., referred to in this proxy statement as ASTeX, in a transaction
accounted for as a pooling-of-interests. Since the fiscal years of MKS and ASTeX
differed, the periods combined for purposes of the following selected historical

     The selected balance sheet data as of December 31, 1999 and 2000 and the
selected statement of income data for the fiscal years ended December 31, 1998,
1999 and 2000 have been derived from MKS financial statements incorporated by
reference into this proxy statement and which have been audited by
PricewaterhouseCoopers LLP, independent accountants. The PricewaterhouseCoopers
LLP report is based in part on the report of other independent accountants. The
selected balance sheet data as of December 31, 1998 and the selected statement
of income data for the fiscal year ended December 31, 1997 have been derived
from MKS financial statements, which are not included in or incorporated by
reference into this proxy statement, and have been audited by
PricewaterhouseCoopers LLP, independent accountants. The PricewaterhouseCoopers
LLP report is based in part on the report of other independent accountants. The
selected balance sheet data as of December 31, 1996 and 1997 and the selected
statement of income data for the fiscal year ended December 31, 1996 have been
derived from unaudited financial statements which are not included in or
incorporated by reference into this proxy statement. The selected statement of
income data for the nine-month periods ended September 30, 2000 and 2001 and the
selected balance sheet data as of September 30, 2001 are unaudited. In the
opinion of MKS' management, all necessary adjustments for a fair statement
(consisting of only normal recurring adjustments) have been included in the
unaudited interim results when read in conjunction with the audited financial
statements and the notes thereto incorporated by reference into this proxy
statement.

     When you read this selected historical consolidated financial data, it is
important that you read the historical consolidated financial statements and
related notes in our annual, quarterly and current reports filed with the
Securities and Exchange Commission, as well as the section of our annual,
quarterly and current reports titled "Management's Discussion and Analysis of
Financial Condition and Results of Operations."

(1) Data is computed on the same basis as Note 2 of Notes to MKS' consolidated
    financial statements for the year ended December 31, 2000 on MKS' Current
    Report on Form 8-K filed November   , 2001, which are incorporated by
    reference in this proxy statement. The historical net income per share data
    of MKS does not include provisions for federal income taxes prior to April
    4, 1999 because MKS was treated as an S corporation for federal and certain
    state income tax purposes. The pro forma statement of income data presents
    net income and net income per share data as if MKS had been subject to
    income taxes as a C corporation during the periods presented. No pro forma
    presentation is necessary for the fiscal year ended December 31, 2000 and
    the nine months ended September 30, 2000 and 2001 because MKS was subject to
    income taxes as a C corporation for these periods.

                          SELECTED HISTORICAL COMBINED
                       FINANCIAL DATA OF THE ENI BUSINESS

     The following table presents selected historical combined financial data of
the ENI business. The statement of income data for the years ended September 30,
1998, 1999 and 2000, and the balance sheet data as of September 30, 1999 and
2000 are derived from the ENI business' audited combined financial statements
included in this proxy statement. The statement of income data for the years
ended September 30, 1996 and 1997, and the balance sheet data as of September
30, 1996, 1997 and 1998 are unaudited and are not included in or incorporated by
reference into this proxy statement. In the opinion of the ENI business'
management, all necessary adjustments (consisting only of normal recurring
adjustments) for a fair statement of the financial position as of September
1996, 1997 and 1998 and the results of operations for the years ended September
30, 1996 and 1997 have been included for the periods presented. The combined
statement of income data for the nine-month periods ended June 30, 2000 and June
30, 2001, and the combined balance sheet data at June 30, 2001 are unaudited. In
the opinion of the ENI business' management, the interim data includes all
necessary adjustments (consisting only of normal recurring adjustments) for a
fair statement of the results for the interim periods. Results for the nine
months ended June 30, 2001 are not necessarily indicative of the results to be
expected for the full year. The data should be read in conjunction with the
combined financial statements, which are included in this proxy statement, and
the section of the proxy statement entitled "Management's Discussion and
Analysis of Financial Condition and Results of Operation of the ENI Business."

(1) Historical net income per share is not applicable to the ENI business as
    there were no shares outstanding. The ENI business is comprised of certain
    worldwide businesses of Emerson which are either divisions of U.S.

    Emerson.

                       CONSOLIDATED FINANCIAL INFORMATION

                     (IN THOUSANDS, EXCEPT PER SHARE DATA)

     On October 30, 2001, MKS agreed to acquire the ENI business. In the
acquisition, MKS will issue 12,000,000 shares of MKS common stock to Emerson or
its subsidiaries. Upon completion of the acquisition, it is expected that
Emerson and its subsidiaries will own approximately 24% of the outstanding
common stock of MKS.

     The following table presents selected unaudited pro forma combined
consolidated financial data of MKS and the ENI business. The data has been
prepared giving effect to the acquisition under the purchase method of
accounting. This information should be read in conjunction with the unaudited
pro forma combined consolidated financial statements and related notes included
elsewhere in this proxy statement. The selected unaudited pro forma combined
financial data is presented for illustrative purposes only and is not

have been achieved had the acquisition been consummated as of dates indicated or
that may be achieved in the future.

                      UNAUDITED COMPARATIVE PER SHARE DATA

     The following table reflects the historical net income and book value per
share of MKS common stock in comparison with unaudited pro forma net income
(loss) and book value per share after giving effect to MKS' pending acquisition
of the ENI business. Historical net income and book value per share are not
applicable to the ENI business as there were no shares outstanding. On January
26, 2001, MKS completed its acquisition of ASTeX in a transaction accounted for
under the pooling-of-interests method of accounting. Since the fiscal years of
MKS and ASTeX differed, the MKS historical comparative per share data presented
below for the year ended December 31, 2000 reflects the combination of the
historical financial statements of MKS for the fiscal year ended December 31,
2000 with the historical financial statements of ASTeX for the fiscal year ended
July 1, 2000. The unaudited pro forma combined financial data are not
necessarily indicative of the operating results that would have been achieved
had the acquisition been consummated as of the beginning of the periods
presented and should not be construed as representative of future operations.
The information in the following table should be read in conjunction with the

(1) Historical book value per share is computed by dividing stockholders' equity
    by the number of shares of common stock outstanding at the end of each
    period presented. Pro forma combined -- per share book value is computed by
    dividing pro forma stockholders' equity by the pro forma number of shares of
    MKS common stock which would have been outstanding had the acquisition been
    consummated as of each balance sheet date.

(2) For the purposes of the pro forma combined net income (loss) per share and
    book value per share data, MKS' historical financial data for the nine
    months ended September 30, 2001 and the year ended December 31, 2000 have
    been combined with the ENI business' financial data for the nine-month
    period ended June 30, 2001 and for the year ended September 30, 2000,
    respectively. The pro forma information was prepared using the purchase
    method of accounting. The net income (loss) per share data assumes the
    acquisition occurred at the beginning of the periods presented and the book
    value per share data assumes the acquisition occurred as of each balance
    sheet date.

                            THE MKS SPECIAL MEETING

     MKS is furnishing this document to holders of MKS common stock in
connection with the solicitation of proxies by the MKS board of directors for
use at the special meeting of MKS stockholders to be held on [Monday, January 7,
2002], and any adjournment of the meeting.

     This document is first being furnished to MKS stockholders on or about
December   , 2001.

DATE, TIME AND PLACE OF MEETING

     The special meeting will be held on [Monday, January 7, 2002], at 10:00
a.m., local time, at the offices of Hale and Dorr LLP, 60 State Street, Boston,
Massachusetts 02109.

WHAT WILL BE VOTED UPON

     At the special meeting, stockholders of MKS will be asked to approve the
issuance of 12,000,000 shares of common stock in connection with the acquisition
of the ENI business and to transact any other business that may properly come
before the special meeting or any postponements or adjournments of that meeting.

RECORD DATE AND OUTSTANDING SHARES

     Only stockholders of record of MKS common stock at the close of business on
Wednesday, November 14, 2001, the record date for the special meeting, are
entitled to notice of and to vote at the special meeting. As of the close of
business on the record date, there were 37,899,862 shares of MKS common stock
outstanding and entitled to vote, held of record by 301 stockholders. Each MKS
stockholder is entitled to one vote for each share of MKS common stock held as
of the record date.

VOTE REQUIRED TO APPROVE THE ISSUANCE

     MKS stockholder approval of the issuance of MKS common stock in connection
with the acquisition is required under the rules of the Nasdaq National Market,
on which MKS' common stock is listed, because the number of shares of MKS common
stock issued in the acquisition will exceed 20% of the number of outstanding
shares of MKS common stock immediately prior to the acquisition. The affirmative
vote of the holders of at least a majority of the shares of MKS common stock
present or represented by proxy at the special meeting is required to approve
the issuance of MKS common stock in connection with the acquisition. John R.
Bertucci, MKS' chairman and chief executive officer, together with members of
Mr. Bertucci's family and trusts for Mr. and Mrs. Bertucci and their immediate
family, who beneficially own 39.54% of all outstanding shares of MKS common
stock as of November 14, 2001, the record date, have agreed to vote in favor of
the issuance of the MKS common stock in connection with the acquisition.

QUORUM; ABSTENTIONS AND BROKER NON-VOTES

     An MKS stockholder may abstain from voting on the proposal to approve the
issuance of MKS common stock in connection with the acquisition by returning a
proxy card marked "ABSTAIN."

     Under applicable rules, brokers who hold shares in street name for
customers have the authority to vote on some routine proposals when they have
not received instructions from beneficial owners. Under applicable rules, these
brokers are precluded from exercising their voting discretion with respect to
the approval and adoption of non-routine matters such as the proposed issuance
of MKS common stock in connection with the acquisition. As a result, absent
specific instructions from the beneficial owner of shares held in street name,
brokers are not empowered to vote these shares to approve the proposed issuance
of MKS common stock in connection with the acquisition.

     Since the required vote to approve the issuance of MKS common stock in
connection with the acquisition is based on the number of shares present or
represented by proxy at the special meeting, rather

                                        16


than outstanding shares, abstentions and broker non-votes will have no effect on
the outcome of the proposal.

VOTING AND REVOCATION OF PROXIES

     The proxy accompanying this document is solicited on behalf of the MKS
board of directors. MKS stockholders are requested to complete, date and sign
the accompanying proxy and promptly return it in the accompanying envelope or
otherwise mail it to MKS. A number of brokerage firms and banks offer telephone
and Internet voting options. If your shares are registered in street name, you
must check the information forwarded by your bank or broker to see which options
are available. Please see the accompanying proxy for more information.

     All properly executed proxies received by MKS prior to the special meeting
that are not revoked will be voted at the special meeting in accordance with the
instructions indicated on the proxies, or, if no direction is indicated, to
approve the issuance of MKS common stock in connection with the acquisition.
MKS' board of directors does not presently intend to bring any other business
before the special meeting and, as of the date of this proxy statement, the
board knows of no other matters to be brought before the special meeting. As to
any other business that may properly come before the special meeting, however,
it is intended that proxies, in the form enclosed, will be voted in accordance
with the judgment of the persons voting those proxies. An MKS stockholder who
has given a proxy may revoke it at any time before it is exercised at the
special meeting by:

     - delivering to the clerk of MKS a written notice, bearing a date later
       than the date of the proxy, stating that the proxy is revoked;

     - signing and delivering prior to the vote at the special meeting a proxy
       relating to the same shares and bearing a later date than the date of the
       previous proxy; or

     - attending the special meeting and voting in person.

     However, if you as an MKS stockholder elect to vote in person at the
special meeting and your shares are held by a broker, bank or other nominee, you
must bring to the special meeting a legal proxy from your broker, bank or other
nominee authorizing you to vote the shares.

SOLICITATION OF PROXIES AND EXPENSES

     MKS will bear the cost of the solicitation of proxies from its
stockholders. MKS has retained Georgeson Shareholder, a proxy solicitation firm,
for assistance in connection with the solicitation of proxies for the MKS
meeting of stockholders at a cost of approximately $8,000, plus reimbursement of
reasonable out of pocket expenses. In addition to solicitation by mail,
brokerage houses and other custodians, nominees and fiduciaries will send
beneficial owners the proxy materials. MKS will, upon request, reimburse those
brokerage houses and custodians for their reasonable expenses incurred in
connection with sending proxy materials. MKS urges its stockholders to vote
proxies without delay.

BOARD RECOMMENDATION

     MKS' BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED THE ACQUISITION, THE
ACQUISITION AGREEMENT AND THE ISSUANCE OF MKS COMMON STOCK IN THE ACQUISITION
AND BELIEVES THAT THE TERMS OF THE ACQUISITION ARE FAIR TO, AND IN THE BEST
INTEREST OF, MKS AND ITS STOCKHOLDERS. THEREFORE, MKS' BOARD OF DIRECTORS
RECOMMENDS THAT MKS STOCKHOLDERS VOTE FOR APPROVAL OF THE ISSUANCE OF MKS COMMON
STOCK NECESSARY TO COMPLETE THE ACQUISITION.

     The proposed acquisition is of great importance to the stockholders of MKS.
Accordingly, MKS' stockholders are urged to read and carefully consider the
information presented in this proxy statement, and to complete, date, sign and
promptly return the enclosed proxy card in the enclosed postage-paid envelope.

                                THE ACQUISITION

     This section of the proxy statement describes material aspects of the
proposed acquisition, including the acquisition agreement. While MKS believes
that the description covers the material terms of the acquisition, this summary
may not contain all of the information that is important to you. You should read
this entire document and the other documents referred to in this proxy statement
carefully for a more complete understanding of the acquisition.

MKS' REASONS FOR THE ACQUISITION

     THE MKS BOARD OF DIRECTORS UNANIMOUSLY CONCLUDED THAT THE ACQUISITION WAS
FAIR TO, AND IN THE BEST INTEREST OF, MKS AND ITS STOCKHOLDERS. ACCORDINGLY,
MKS' BOARD RECOMMENDS THAT MKS STOCKHOLDERS VOTE FOR APPROVAL OF THE ISSUANCE OF
SHARES OF MKS COMMON STOCK TO EMERSON IN CONNECTION WITH THE ACQUISITION.

     The decision of the board of directors was based on several potential
benefits of the acquisition that it believes will contribute to MKS' success.
These potential benefits include:

     - adding critical solid-state power conversion technology to MKS'
       portfolio;

     - achieving synergies by combining MKS' high power RF power business and
       the ENI solid state power delivery business;

     - offering more highly integrated and higher value/performance plasma
       delivery products;

     - leveraging research and development investment;

     - leveraging global infrastructure and supply chain management;

     - leveraging the strong geographical and cultural fit of MKS and ENI;

                                        19


     - augmenting MKS' position as a leading provider of OEM subsystem solutions
       to the semiconductor capital equipment industry; and

     - the acquisition is expected to be accretive to MKS' cash earnings per
       share in 2002.

     The MKS board of directors reviewed a number of factors in evaluating the
acquisition, including but not limited to the following:

     - opinion of MKS' financial advisor, Merrill Lynch;

     - historical information concerning MKS' and the ENI business' respective
       business focus, financial performance and condition, operations,
       technology and management;

     - MKS management's view of the financial condition, results of operations
       and business of MKS and the ENI business before and after giving effect
       to the acquisition and the determination by the MKS board of directors of
       the acquisition's effect on MKS stockholder value;

     - current financial market conditions and historical stock market prices,
       volatility and trading information;

     - the consideration MKS will pay in the acquisition in light of comparable
       acquisitions;

     - the terms of the acquisition agreement, shareholder agreement and voting
       agreement;

     - the impact of the acquisition on MKS' customers and employees;

     - results of the due diligence investigation conducted by MKS' management,
       accountants and counsel; and

     - the expectation that the acquisition will be accounted for as a purchase
       for accounting purposes.

     During the course of its deliberations concerning the acquisition, the MKS
board of directors also identified and considered a variety of potentially
negative factors that could materialize as a result of the acquisition,
including but not limited to the following:

     - the risk that the potential benefits sought in the acquisition might not
       be fully realized;

     - the possibility that the acquisition might not be completed, even if
       approved by the MKS stockholders;

     - the effect of the public announcement of the acquisition on MKS' business
       and the ENI business, including employees and customers; and

     - the risks associated with obtaining the necessary approvals required to
       complete the acquisition.

     The MKS board of directors concluded that these factors were outweighed by
the potential benefits to be gained by the acquisition. In view of the wide
variety of factors, both positive and negative, considered by the MKS board of
directors, the directors did not find it practical to, and did not, quantify or
otherwise assign relative weights to the specific factors discussed above.

RECOMMENDATIONS OF MKS' BOARD OF DIRECTORS

     AFTER CAREFUL CONSIDERATION, THE MKS BOARD OF DIRECTORS HAS DETERMINED THE
ISSUANCE OF MKS COMMON STOCK IN CONNECTION WITH THE ACQUISITION TO BE FAIR TO
MKS STOCKHOLDERS AND IN THEIR BEST INTEREST AND DECLARED THE ISSUANCE ADVISABLE.
MKS' BOARD OF DIRECTORS UNANIMOUSLY APPROVED THE ISSUANCE OF MKS COMMON STOCK IN
CONNECTION WITH THE ACQUISITION AND RECOMMENDS APPROVAL OF THE ISSUANCE BY MKS'
STOCKHOLDERS.

OPINION OF MKS' FINANCIAL ADVISOR

     MKS retained Merrill Lynch, Pierce, Fenner & Smith Incorporated to act as
its financial advisor in connection with the proposed acquisition from Emerson
of the ENI business. In connection with that

                                        20


engagement, MKS requested that Merrill Lynch evaluate whether the issuance of
the acquisition consideration in exchange for the ENI business, which we refer
to in this proxy statement as the Exchange, was fair from a financial point of
view to MKS. At a meeting of the board of directors of MKS on October 30, 2001,
Merrill Lynch delivered its oral opinion to the board of directors of MKS,
subsequently confirmed in writing, that as of October 30, 2001, based upon the
assumptions made, matters considered and limits of such review, as such are set
forth in the opinion, the Exchange was fair, from a financial point of view, to
MKS.

     The full text of the Merrill Lynch opinion, which sets forth the
assumptions made, matters considered and certain qualifications and limitations
on the scope of the review undertaken by Merrill Lynch, is attached as Annex B
to this proxy statement and is incorporated herein by reference. The summary of
the Merrill Lynch opinion set forth below is qualified in its entirety by
reference to the full text of the opinion, and you are urged to read the Merrill
Lynch opinion in its entirety and consider it carefully.

     The Merrill Lynch opinion was addressed to the board of directors of MKS
for its information and was directed only to the fairness, from a financial
point of view, of the Exchange to MKS. The Merrill Lynch opinion did not address
any other aspect of the acquisition, including the underlying decision by MKS to
engage in the acquisition, and does not constitute, nor should it be construed
as, a recommendation to any shareholder of MKS as to how such shareholder should
vote on the proposed issuance by MKS of shares of MKS common stock in the
acquisition or any other matter related to the acquisition.

     In addition, Merrill Lynch did not express any opinion as to the prices at
which the MKS common stock might trade subsequent to the consummation of the
acquisition.

     In arriving at its opinion, Merrill Lynch, among other things:

     - reviewed certain publicly available business and financial information
       relating to MKS and the ENI business that Merrill Lynch deemed to be
       relevant;

     - reviewed certain information, including financial forecasts, relating to
       the business, earnings, cash flow, assets, liabilities and prospects of
       MKS and the ENI business, furnished to, or discussed with, Merrill Lynch
       by Emerson, the ENI business, and MKS, respectively;

     - conducted discussions with members of senior management and
       representatives of Emerson, the ENI business and MKS concerning the
       matters described in the above clauses, as well as their respective
       businesses and prospects before and after giving effect to the
       acquisition;

     - reviewed the market prices and valuation multiples for shares of MKS
       common stock and compared them with those of certain publicly traded
       companies that Merrill Lynch deemed to be relevant;

     - reviewed the results of operations of the ENI business and MKS and
       compared them with those of certain publicly traded companies that
       Merrill Lynch deemed to be relevant;

     - compared the proposed financial terms of the acquisition with the
       financial terms of certain other transactions that Merrill Lynch deemed
       to be relevant;

     - participated in certain discussions among representatives of Emerson, the
       ENI business and MKS and their respective financial and legal advisors;

     - reviewed the potential pro forma impact of the acquisition;

     - reviewed a draft dated October 30, 2001, of the acquisition agreement;
       and

     - reviewed such other financial studies and analyses and took into account
       such other matters as Merrill Lynch deemed necessary, including its
       assessment of general economic, market and monetary conditions.

                                        21


     In preparing its opinion, Merrill Lynch assumed and relied on the accuracy
and completeness of all information supplied or otherwise made available to it,
discussed with or reviewed by or for it, or made publicly available. Merrill
Lynch did not assume any responsibility for independently verifying any such
information and did not undertake an independent evaluation or appraisal of any
assets, properties or liabilities of the ENI business or MKS, and was not
furnished with any such evaluation or appraisal. In addition, Merrill Lynch did
not assume any obligation to conduct, nor did it conduct, any physical
inspection of the assets, properties or facilities of the ENI business or MKS.
With respect to the financial forecast information furnished to or discussed
with Merrill Lynch by Emerson, the ENI business or MKS, Merrill Lynch assumed
that such information had been reasonably prepared and reflected the best
currently available estimates and judgments of Emerson's, the ENI business' or
MKS' management as to the expected future financial performance of the ENI
business or MKS, as the case may be. Merrill Lynch further assumed that the
acquisition would be accounted for using the new purchase accounting guidelines
under generally accepted accounting principles and would qualify as a tax-free
reorganization for U.S. federal income tax purposes (and as having certain other
tax effects outside of the United States).

     The Merrill Lynch opinion was necessarily based upon market, economic and
other conditions as they existed and could be evaluated on, and on the
information made available to Merrill Lynch, as of October 30, 2001. Merrill
Lynch assumed that in the course of obtaining the necessary regulatory or other
consents or approvals (contractual or otherwise) for the acquisition, no
restrictions, including any divestiture requirements or amendments or
modifications, would be imposed that will have a material adverse effect on the
contemplated benefits of the acquisition. Merrill Lynch also assumed that the
acquisition would be consummated in accordance with the terms of the acquisition
agreement without waiver of any material condition.

     In performing its analyses, Merrill Lynch made numerous assumptions with
respect to industry performance, general business, economic, market and
financial conditions and other matters, many of which are beyond the control of
Merrill Lynch, MKS, Emerson and the ENI business. Any estimates contained in the
analyses performed by Merrill Lynch are not necessarily indicative of actual
values or future results, which may be significantly more or less favorable than
suggested by such analyses. Additionally, estimates of the value of businesses
or securities do not purport to be appraisals of or to reflect the prices at
which such businesses or securities might actually be sold. Accordingly, such
analyses and estimates are inherently subject to substantial uncertainty. In
addition, as described above, the Merrill Lynch opinion was among several
factors taken into consideration by the board of directors of MKS in making its
determination to approve the acquisition agreement and the acquisition.
Consequently, Merrill Lynch's analyses should not be viewed as determinative of
the decision of the MKS board of directors or MKS' management with respect to
the fairness to MKS of the Exchange as contemplated by the acquisition
agreement.

     At the meeting of the MKS board of directors held on October 30, 2001,
Merrill Lynch presented certain financial analyses accompanied by written
materials in connection with the delivery of its oral opinion at that meeting
and its subsequent delivery of its written opinion as of October 30, 2001.

     The following is a summary of certain material financial analyses performed
by Merrill Lynch in arriving at its opinion. Some of the financial analyses
summarized below include information presented in a tabular format. In order to
understand fully Merrill Lynch's financial analyses, the tables must be read
together with the text of the summary. The tables alone do not constitute a
complete description of the financial analyses. Considering the data set forth
below in tables without considering the full narrative description of the
financial analyses, including the methodologies and assumptions underlying the
analyses, could create a misleading or incomplete view of the financial analyses
performed by Merrill Lynch.

     The ENI Business

     PUBLICLY TRADED COMPARABLE COMPANIES ANALYSIS.  Merrill Lynch compared
selected financial and operating data of the ENI business with corresponding
data for certain publicly traded comparable companies that Merrill Lynch deemed
relevant for the purposes of its analysis. The comparable companies

                                        22


were selected because they engage in businesses reasonably comparable to those
of the ENI business and are as follows:

                              COMPARABLE COMPANIES


                                        
- Advanced Energy Industries Inc.          - Helix Technology Corp.
- ATMI Inc.                                - MKS Instruments, Inc.
- Cymer Inc.                               - Mykrolis Corp.
- Entegris Inc.


     Using publicly available information and estimates of future results
published by equity analysts covering each of the comparable companies, Merrill
Lynch determined the ratio for each of the comparable companies of enterprise
value (defined as market value (diluted shares outstanding calculated using the
treasury stock method multiplied by stock price) plus total debt plus preferred
stock plus minority interests less cash and cash equivalents) to projected
revenue for each of calendar years 2001 and 2002, and applied these multiples to
the estimated revenue of the ENI business for each of calendar years 2001 and
2002. The following table presents the implied equity value range of the ENI
business (determined by multiplying the enterprise value to revenue multiple by
the estimated revenue of the ENI business minus net debt of the ENI business)
based on such analyses.



                                                                  ENI BUSINESS
                                                              IMPLIED EQUITY VALUE
                                                              --------------------
                                                                 (IN MILLIONS)
                                                                LOW         HIGH
                                                              --------    --------
                                                                    
Implied Equity Value of the ENI Business....................   $101.5      $311.8


     Merrill Lynch observed that the implied offer value of $247.8 million
(calculated as 12 million shares of MKS common stock at the $20.65 closing price
per share on October 29, 2001) was within the range of the low and high implied
equity values for the ENI business based on the public comparable revenue
multiple approach. In addition, the implied offer value was within the low and
high implied equity value for the ENI business as calculated for each of
calendar years 2001 and 2002 using the estimated revenue of the ENI business for
calendar years 2001 and 2002 and the applicable revenue multiples of the
comparable companies.

     None of the publicly traded comparable companies utilized in the above
analysis for comparative purposes is identical to the ENI business. In
evaluating companies identified by Merrill Lynch as comparable to the ENI
business, Merrill Lynch made judgments and assumptions with regard to industry
performance, general business, economic, market and financial conditions and
other matters, many of which are beyond the control of the ENI business and the
industry generally, industry growth and the absence of any material change in
the financial condition and prospects of the ENI business or the industry or in
the financial markets generally. A complete analysis involves complex
considerations and judgments concerning differences in financial and operating
characteristics of the comparable companies and other factors that could affect
the public trading values of the comparable companies to which the ENI business
was compared; mathematical analysis is not in itself a meaningful method of
using selected company data.

     COMPARABLE ACQUISITION ANALYSIS.  Using publicly available information,
Merrill Lynch examined the following transactions that it deemed relevant, to
determine the multiples of transaction enterprise value to last twelve months
(LTM) revenue and EBITDA (earnings before interest, taxes, depreciation and
amortization), and the offer price to LTM cash earnings. The comparable
acquisitions considered by Merrill Lynch were the following:

Oerlikon-Buhrle Holding AG...................   Plasma-Therm Inc.
Veeco Instruments Inc. ......................   Ion Tech Inc.
Advanced Energy Industries Inc. .............   RF Power Products Inc.
Helix Technology Corp. ......................   Granville-Phillips


     All multiples for the selected transactions were based on information
publicly available at the time of the public announcement of the applicable
transaction, and Merrill Lynch did not take into account different market and
other conditions during the period in which the selected transactions occurred.
The comparable transaction analysis yielded the following mean and median
multiples of revenue, EBITDA and cash earnings for the last twelve months:



                                                              MEAN    MEDIAN
                                                              -----   ------
                                                                
Transaction Value to LTM Revenue............................  2.43x   1.83x
Transaction Value to LTM EBITDA.............................  10.8x   11.1x
Offer Price to Cash Earnings................................  22.0x   19.3x


     Merrill Lynch observed that the implied transaction multiples of enterprise
value to LTM revenue and EBITDA, and offer price to LTM cash earnings being paid
by MKS to Emerson for the ENI business were within or below the mean and median
of comparable transactions.

     No company or transaction examined in the comparable acquisitions analysis
is identical to the ENI business or the acquisition. A complete analysis of the
results of the foregoing comparable acquisitions involves complex considerations
and judgments concerning differences in financial and operating characteristics
of the companies included in the comparable acquisitions transaction analysis
and other factors that could affect the transaction value and the transaction
multiples of the comparable transactions to which the acquisition is being
compared; mathematical analysis (such as determining the mean or the median) is
not itself a meaningful method of using selected transaction data.

     DISCOUNTED CASH FLOW ANALYSIS.  Merrill Lynch performed a discounted cash
flow analysis of the ENI business, without giving effect to the acquisition, for
the calendar years 2001 through (and including) 2005. Merrill Lynch calculated a
range of equity values for the ENI business based upon the sum of the discounted
net present value of the five-year stream of projected free cash flows plus the
discounted net present value of the terminal value based on a range of multiples
of its projected 2005 EBITDA and a range of discount rates.

     Using discount rates ranging from 16.0% to 20.0% and terminal value
multiples of estimated calendar year 2005 EBITDA ranging from 8.0x to 12.0x,
Merrill Lynch calculated the following range of implied equity value for the ENI
business:



                                                                  ENI BUSINESS
                                                              IMPLIED EQUITY VALUE

                                                                 (IN MILLIONS)
                                                                LOW         HIGH
                                                              --------    --------
                                                                    
Implied Equity Value of the ENI Business....................   $248.4      $414.7


                                        24


     Merrill Lynch observed that the implied offer value being paid by MKS in
connection with the acquisition was below the low-end equity value of the ENI
business as determined using the discounted cash flow analysis.

     MKS Instruments, Inc.

     TRADING ANALYSIS.  Merrill Lynch reviewed the recent trading performance of
shares of MKS common stock. The per share closing price trading data for the six
month, three month, one month and ten day periods ending on October 29, 2001, is
summarized in the table below:



                                                               MKS INSTRUMENTS

     ANALYSIS OF RESEARCH FORECASTS.  Merrill Lynch compared Wall Street
research forecasts for MKS published after MKS' October 16, 2001 earnings
announcement. The mean of revenue, gross profit margin and cash earnings per
share estimates of such review were discussed with MKS' management and utilized
as the MKS' forecasted information for this analysis.

     PUBLICLY TRADED COMPARABLE COMPANIES ANALYSIS.  Merrill Lynch compared
selected financial and operating data of MKS with corresponding data for certain
publicly traded comparable companies that Merrill Lynch deemed relevant for the
purposes of its analysis. The publicly traded comparable companies were selected
because they engage in businesses reasonably comparable to those of MKS and are
as follows:

                              COMPARABLE COMPANIES


                                        
- Advanced Energy Industries Inc.          - Entegris Inc.
- ATMI Inc.                                - Helix Technology Corp.
- Cymer Inc.                               - Mykrolis Corp.


     Using publicly available information and estimates of future results
published by equity analysts covering each of the comparable companies, Merrill
Lynch determined the ratio for each of the comparable companies of enterprise
value to estimated revenue for each of calendar years 2001 and 2002, and applied
these multiples to the estimated revenues of MKS for each of calendar years 2001
and 2002. The following table presents the implied equity value per share of MKS
based on such analyses.



                                                              MKS INSTRUMENTS
                                                              IMPLIED EQUITY
                                                              VALUE PER SHARE
                                                              ---------------
                                                               LOW      HIGH
                                                              ------   ------
                                                               ($ PER SHARE)
                                                                 
Implied Equity Value per share of MKS Common Stock..........  $10.95   $29.00


     Merrill Lynch observed that the per share price of MKS common stock on
October 29, 2001, of $20.65 was within the high and low implied per share equity
value for MKS as calculated for each of calendar years 2001 and 2002 using the
revenue multiples of the comparable companies.

     None of the comparable companies utilized in the above analyses for
comparative purposes is identical to MKS. In evaluating companies identified by
Merrill Lynch as comparable to MKS, Merrill Lynch made judgments and assumptions
with regard to industry performance, general business, economic, market and
financial conditions and other matters, many of which are beyond the control of
MKS and the

                                        25


industry generally, industry growth and the absence of any material change in
the financial condition and prospects of MKS or the industry or in the financial
markets generally. A complete analysis involves complex considerations and
judgments concerning differences in financial and operating characteristics of
the comparable companies and other factors that could affect the public trading
values of the comparable companies to which MKS is being compared; mathematical
analysis is not in itself a meaningful method of using selected company data.

     DISCOUNTED CASH FLOW ANALYSIS.  Merrill Lynch performed a discounted cash
flow analysis of MKS, without giving effect to the acquisition, for the calendar
years 2001 through (and including) 2005. Merrill Lynch calculated a range of
equity values per share of MKS common stock based upon the sum of the discounted
net present value of the five-year stream of projected free cash flows plus the
discounted net present value of the terminal value based on a range of multiples
of its projected 2005 EBITDA and a range of discount rates.

     Using discount rates ranging from 16.0% to 20.0% and terminal value
multiples of estimated calendar year 2005 EBITDA ranging from 8.0x to 12.0x,
Merrill Lynch calculated the following range of implied equity values per share
of MKS common stock:



                                                              MKS INSTRUMENTS
                                                              IMPLIED EQUITY
                                                              VALUE PER SHARE
                                                              ---------------
                                                               LOW      HIGH
                                                              ------   ------
                                                               ($ PER SHARE)
                                                                 
Implied Equity Value per share of MKS Common Stock..........  $17.49   $26.87


     Merrill Lynch observed that the price per share of MKS common stock on
October 29, 2001, of $20.65 was within the range of implied equity values per
share of MKS common stock as determined using the discounted cash flow analysis.

     RELATIVE VALUATION ANALYSIS.

  Relative Contribution to Operating Results

     Merrill Lynch analyzed the relative contributions by MKS and the ENI
business to revenue and gross profit of the combined entity for the last twelve
months and forecasted calendar years 2001 and 2002. This analysis was performed
without taking into account any potential synergies which might result from the
consummation of the acquisition. Using the estimated revenue and gross profit
amounts and the treasury stock method of calculating the number of shares of MKS
common stock outstanding, Merrill Lynch observed the following implied share
consideration (in numbers of shares):



                                                               IMPLIED SHARE
                                                               CONSIDERATION

                                                               COMMON STOCK)
                                                                  
Revenue Contribution Method.................................  11.3      13.2
Gross Profit Contribution Method............................  12.6      14.9


     Merrill Lynch observed that the acquisition consideration of 12 million
shares of MKS common stock to be issued by MKS to Emerson in connection with the
acquisition was within the implied share consideration utilizing the relative
revenue contribution method and below the implied share consideration as
calculated utilizing the relative gross profit contribution method by the ENI
business to the combined entity for the last twelve months and calendar years
2001 and 2002.

     RELATIVE PUBLICLY TRADED COMPARABLE COMPANIES ANALYSIS.  Merrill Lynch,
utilizing the publicly traded comparable companies analysis performed for each
of the ENI business and MKS (as described in "-- The ENI Business -- Publicly
Traded Comparable Companies Analysis" and "-- MKS Instruments, Inc. -- Publicly
Traded Comparable Companies Analysis," respectively), calculated the high and
low implied share consideration (in number of shares) using a relative
percentage determined by dividing the

                                        26


implied equity value of the ENI business by the sum of the implied equity values
of each of the ENI business and MKS. Based upon this analysis, the range of
implied share consideration (in number of shares) was as follows:

Implied Share Consideration.................................   4.1       25.8


     Merrill Lynch observed that the acquisition consideration of 12 million
shares of MKS common stock to be issued by MKS to Emerson in connection with the
acquisition was within the range of high and low implied share consideration
calculated using the relative publicly traded comparable companies analysis.

     RELATIVE DISCOUNTED CASH FLOW ANALYSIS.  Merrill Lynch, utilizing the
discounted cash flow analysis performed for each of the ENI business and MKS (as
described in "-- The ENI Business -- Discounted Cash Flow Analysis" and "-- MKS
Instruments, Inc. -- Discounted Cash Flow Analysis," respectively), calculated
the high and low implied share consideration (in number of shares) using a
relative percentage determined by dividing the implied equity value of the
discounted cash flow analysis for the ENI business by the sum of the implied
equity values of the discounted cash flow analysis for each of the ENI business
and MKS. Based upon this analysis, the range of implied share consideration (in
number of shares) was as follows:



                                                               IMPLIED SHARE

Implied Share Consideration.................................   8.5       21.8


     Merrill Lynch observed that the acquisition consideration of 12 million
shares of MKS common stock to be issued by MKS to Emerson in connection with the
acquisition was within the range of high and low implied share consideration
calculated using the relative discounted cash flow analysis.

     PRO FORMA COMBINATION ANALYSIS.  Merrill Lynch also analyzed certain pro
forma effects which are expected to result from the acquisition. Merrill Lynch
compared the projected cash earnings per share of MKS common stock on a
stand-alone basis, assuming the acquisition did not occur, to the cash earnings
per share of MKS common stock assuming the acquisition is consummated. This
analysis was performed without taking into account any potential synergies which
might result from the consummation of the acquisition.

     Taking into account the assumptions set forth above, the pro forma
combination analysis indicated that the acquisition would be accretive to the
projected cash earnings per share of MKS common stock in calendar year 2002
without consideration of any synergies.

     OTHER FACTORS.  In preparing its opinion to the board of directors of MKS,
Merrill Lynch performed a variety of financial and comparative analyses,
including those described above. The summary set forth above does not purport to
be a complete description of the analyses underlying the Merrill Lynch opinion
or the presentation made by Merrill Lynch to the board of directors of MKS. The
preparation of a fairness opinion is a complex analytic process involving
various determinations as to the most appropriate and relevant methods of
financial analysis and the application of those methods to the particular
circumstances and, therefore, a fairness opinion is not readily susceptible to
partial analysis or summary description. In arriving at its opinion, Merrill
Lynch did not attribute any particular weight to any analysis or factor
considered by it, but rather made qualitative judgments regarding the
significance and relevance of each analysis and factor. Accordingly, Merrill
Lynch believes its analyses must be considered as a whole and

                                        27


that selecting only portions of its analyses and factors, or focusing on
information presented in tabular format, without considering all of the analyses
and factors or the narrative description of the analyses, could create an
incomplete or misleading view of the processes underlying its opinion.

     The board of directors of MKS selected Merrill Lynch to render a fairness
opinion because Merrill Lynch is an internationally recognized investment
banking firm with substantial experience in transactions similar to the
acquisition. Merrill Lynch continually is engaged in the valuation of businesses
and their securities in connection with mergers and acquisitions and for other
purposes and has substantial experience in transactions similar to the merger.

     MKS has agreed to pay to Merrill Lynch a customary fee for its services and
also agreed to reimburse Merrill Lynch for its reasonable out-of-pocket expenses
(including reasonable fees and expenses of its legal counsel) incurred in
connection with its engagement as financial advisor. All of Merrill Lynch's fee
will be paid upon consummation of the acquisition. In addition, MKS has agreed
to indemnify Merrill Lynch and certain related persons against certain
liabilities arising out of or in conjunction with the services rendered by
Merrill Lynch under its engagement, including certain liabilities under federal
securities laws.

     In the ordinary course of business, Merrill Lynch may actively trade the
equity and debt securities of MKS and Emerson for its own account and for the
accounts of its customers and, accordingly, may at any time hold a long or short
position in such securities.

     Merrill Lynch's fairness opinion is for the use and benefit of the board of
directors of MKS. It does not address the merits of the underlying decision by
MKS to engage in the acquisition and does not constitute a recommendation to any
shareholder of MKS as to how to vote on the proposed acquisition or any matter
related thereto.

INTERESTS OF EXECUTIVE OFFICERS AND DIRECTORS OF MKS IN THE ACQUISITION

     As of October 31, 2001, all MKS directors, executive officers and
affiliates, including John R. Bertucci, chairman of the board of directors and
chief executive officer of MKS, beneficially owned in the aggregate
approximately 46% of the outstanding shares of MKS common stock. See "MKS'
Principal Shareholders." All directors and executive officers of MKS have
indicated their intention to vote all shares over which they exercise voting
control in favor of the issuance of MKS common stock in connection with the
acquisition.

     Mr. Bertucci, his wife, and family trusts controlled by them have entered
into a voting agreement with Emerson relating to the proposed acquisition. As of
the record date for the special meeting, these parties collectively owned
approximately 39% of the outstanding shares of MKS common stock. In the voting
agreement, these parties agreed to vote all of the shares of MKS common stock
over which they exercise voting control in favor of the issuance of MKS common
stock in connection with the acquisition. These parties executed an irrevocable
proxy that enables Emerson to vote the shares to approve the issuance of MKS
common stock in connection with the acquisition. These parties were not paid
additional consideration in connection with the irrevocable proxy. See "Related
Agreements -- Voting Agreement."

ACCOUNTING TREATMENT OF THE ACQUISITION

     In accordance with the recently issued Statement of Financial Accounting
Standards No. 141, "Business Combinations," and Statement of Financial
Accounting Standards No. 142, "Goodwill and Other Intangible Assets," MKS will
use the purchase method of accounting for a business combination to account for
the acquisition, as well as the new accounting and reporting regulations for
goodwill and other intangibles. Under these methods of accounting, the assets
and liabilities of the ENI business, including intangible assets, will be
recorded at their respective fair values. All intangible assets will be
amortized over their estimated useful lives with the exception of goodwill and
any other intangibles with indefinite lives. The financial position, results of
operations and cash flows of the ENI business will be included in MKS' financial
statements prospectively as of the completion of the acquisition.

                                        28


REGULATORY APPROVALS

     Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended,
MKS may not complete the acquisition of the ENI business until notifications
have been furnished to the Federal Trade Commission and the Antitrust Division
of the Department of Justice and the required waiting period has been satisfied
or terminated. MKS and Emerson each filed a pre-acquisition notification and
report form with the Federal Trade Commission and the Antitrust Division of the
Department of Justice on November 9, 2001. On           , 2001, MKS and Emerson
received notice from the Federal Trade Commission that the applicable waiting
period under the Hart-Scott-Rodino Act was terminated. As a result, the
acquisition may be consummated, pending compliance with the other closing
conditions.

     At any time before the closing of the acquisition, the Antitrust Division
of the Department of Justice, the Federal Trade Commission or a private person
or entity could seek under antitrust laws, among other things, to enjoin the
acquisition and any time after the closing of the acquisition, to cause MKS to
divest itself, in whole or in part, of the ENI business. There can be no
assurance that a challenge to the acquisition will not be made or that, if a
challenge is made, MKS will prevail. The obligations of MKS and Emerson to
complete the acquisition was subject to the condition that any applicable
waiting period under the Hart-Scott-Rodino Act shall have expired without action
by the Antitrust Division of the Department of Justice or the Federal Trade
Commission to prevent completion of the acquisition. See "The Acquisition
Agreement -- Conditions to Obligations to Effect the Acquisition."

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

     There will be no United States federal income tax consequences to the
holders of MKS common stock as a result of the completion of the acquisition.

                                        29


                           THE ACQUISITION AGREEMENT

     The following is a brief summary of the material provisions of the
acquisition agreement, a copy of which is attached as Annex A to this proxy
statement and is incorporated by reference into this summary. While we believe
that the summary covers the material terms of the acquisition agreement, this
summary may not contain all of the information that is important to you. We urge
all MKS stockholders to read the acquisition agreement in its entirety for a
more complete description of the terms and conditions of the acquisition and
related matters.

GENERAL

     At or prior to the closing of the acquisition, Emerson shall reorganize the
ENI business so that the assets used in and the liabilities relating to or
arising out of the conduct of the ENI business are located in one of the
following companies: ENI Japan, a Japanese corporation, ENI Technology, Inc., a
Delaware corporation, ENI Taiwan Limited, a Taiwanese corporation, ENI Hong
Kong, a corporation to be formed under the laws of Hong Kong, ENI China, a
corporation to be formed under the laws of the People's Republic of China, and
Astec Germany GmbH, a German corporation.

     Following the approval of the issuance of shares of MKS common stock to

     This consideration shall be paid as follows:

       ENI business; and

     - an aggregate of $1,500,000 will be paid by a subsidiary of MKS to Astec

     At the closing of the acquisition, Emerson or a subsidiary of Emerson shall
pay $10,500,000 to MKS to purchase a total of 508,475 shares of MKS common
stock.

     Subsidiaries of MKS in Japan and Germany shall assume all of the
liabilities of ENI Japan and Astec Germany GmbH, respectively, associated with
the ENI business, with the exception of certain excluded liabilities as set

COVENANTS

     Each of MKS and Emerson has agreed to use its reasonable best efforts to
take all actions and to do all things necessary, proper or advisable, and to
cause their respective subsidiaries to take all actions and to do all things
necessary, proper or advisable, to consummate the transactions contemplated by
the acquisition agreement.

     Governmental and Third-Party Notices and Consents.  MKS and Emerson have
each agreed to use their reasonable best efforts to obtain, at their own
expense, all waivers, approvals, or consents from third parties and give notice
to all third parties which are necessary to be obtained by them to consummate

other authorizations from governmental entities and to effect all registrations,

regulations in connection with the consummation of the acquisition. The

filings, providing information or resolving any challenge that may arise under
any applicable anti-trust laws or from the Federal Trade Commission or Antitrust
Division of the Department of Justice.

     Proxy Statement and Stockholders Meeting.  MKS agreed to prepare and file a
proxy statement, and any amendments to such proxy statement, with the Securities
and Exchange Commission.

     MKS further agreed to take all actions in accordance with applicable law
and its articles of organization and by-laws to promptly and duly call, give
notice of and convene a meeting of the MKS stockholders for the purpose of
approving the issuance of 12,000,000 shares of MKS common stock to Emerson in
connection with the acquisition.

     Operations of the ENI Business Prior to Acquisition.  Except as
contemplated by the acquisition agreement, Emerson has agreed that it and its
subsidiaries will conduct operations relating to the ENI business in the
ordinary course of business and in compliance with applicable laws.
Specifically, Emerson has agreed to use its reasonable best efforts to keep the
physical assets to be transferred to MKS or its subsidiaries as set forth in the
acquisition agreement in good working condition, to keep available the services
supplied to, and preserve relationships with, suppliers and customers of the ENI
business.

     In addition, with respect to the ENI business, Emerson agreed that, except
as contemplated by the acquisition agreement or the reorganization of the ENI
business, each of its subsidiaries that operate the ENI business will not,
without the prior written consent of MKS:

     - issue or sell any stock or other equity securities;

     - assume, guarantee, endorse or otherwise become liable or responsible for
       obligations of any person or entity which is not an affiliate of Emerson;

     - make any loans, advances or capital contributions to, or investments in,
       any person or entity not an affiliate of Emerson;

     - enter into, adopt or amend any employee benefit plan or employment or
       severance arrangement of the type set forth in the acquisition agreement
       or increase in any material respect the compensation or fringe benefits
       of its employees or directors;

     - materially modify the employment terms of its directors, officers or
       employees, or, except for existing payment obligations set forth in the
       acquisition agreement, pay any bonus or any other benefit, unless done in
       the ordinary course pursuant to existing benefit plans or arrangements;

     - hire any new officers or, except in the ordinary course of business, any
       new employees;

       $25,000 for any individual legal proceeding, and $100,000 in the
       aggregate; or

     - agree in writing or otherwise to take any of the actions listed above.

     Emerson agreed to prohibit ENI Technology, Inc., ENI Hong Kong, ENI Japan
and ENI Taiwan from declaring, setting aside or paying any dividend or other
distribution (other than a distribution intended to remove assets which are
excluded from the transaction by the terms of the acquisition agreement) in
respect of capital stock, or redeeming or purchasing any of its capital stock,
without the written consent of MKS.

     Emerson further agreed, at or prior to the closing of the acquisition, to
remove all cash from the ENI business, except for $1,500,000 which shall remain
in the ENI business after the closing of the acquisition, to eliminate or
otherwise settle all intercompany accounts and to eliminate all of the debt of
the ENI business other than the liabilities that the subsidiaries of MKS will
assume and debt related to the IDRB Lease.

     Access to Information.  As is reasonably appropriate, Emerson agreed to
provide MKS with access to all premises, properties, personnel, environmental
and financial records, contracts and other documents of Emerson and each of its
subsidiaries which conducts the ENI business, except that this right cannot be
used to conduct intrusive testing at any site without Emerson's consent.

     Board of Directors of MKS.  MKS agreed to increase the size of its board of
directors to eight and, effective as of the closing of the acquisition, to cause
James G. Berges, or upon his inability or refusal to serve, another individual
selected by Emerson and reasonably acceptable to MKS, to be appointed to fill
the vacancy created by the increase. Mr. Berges, or another individual selected
by Emerson, will serve as a member of the class of directors whose term will
expire at the MKS annual meeting of stockholders to be held in 2004.

     MKS is Restricted From Soliciting Another Party. Except for specified
exceptions, the acquisition agreement contains detailed provisions prohibiting
MKS from seeking an alternative transaction. Under these "no solicitation"
provisions, MKS has agreed that neither it nor any of its subsidiaries,
officers, directors, employees, investment bankers, attorneys, accountants,
consultants or other agents, will, directly or indirectly:

     - initiate, solicit, encourage or facilitate any inquiries or proposals
       that constitute or could reasonably be expected to lead to an acquisition
       proposal;

     - enter into, participate in any discussions or negotiations regarding,
       furnish to any person any information regarding MKS or its subsidiaries,
       afford any person access to the business, properties, assets, books or
       records of MKS or otherwise cooperate or assist in facilitating or
       encouraging any effort by any person making an acquisition proposal; or

     - grant any waiver or release under any "standstill" or similar agreement
       with respect to any class of equity securities of MKS or its
       subsidiaries.

     "Acquisition proposal" means, with respect to any entity, any proposal or
offer with respect to, or a transaction to effect:

     - a merger, consolidation, dissolution, sale of substantial assets, tender
       offer, recapitalization, share exchange or other business combination
       involving MKS or its subsidiaries;
                                        34


     - the issuance by MKS or its subsidiaries of over 10% of its equity
       securities; or

     - the acquisition, in any manner, directly or indirectly, of over 10% of
       the equity securities or consolidated assets of MKS,

which, in each case, is contingent upon the rejection by the MKS stockholders of
the issuance of 12,000,000 shares of MKS common stock to Emerson in connection
with the acquisition.

     However, prior to the approval by the MKS stockholders of the issuance of
the shares of MKS common stock contemplated by the acquisition agreement, MKS
may, to the extent required to comply with the fiduciary duties of the MKS board
of directors under applicable law, as determined by a majority vote of the full
board of directors after consultation with MKS' outside counsel and financial
advisor, supply information with respect to MKS to, and negotiate with, a person
making an acquisition proposal which did not result in a breach of the
"non-solicit" covenant of MKS in the acquisition agreement. Prior to receiving
any information or engaging in any negotiations, the person making an
acquisition proposal must execute a customary confidentiality agreement which is
no less restrictive than the confidentiality agreement executed by Emerson. MKS
has agreed to notify Emerson promptly in writing of the existence of any
acquisition proposal and whether such acquisition proposal is, or becomes,
contingent on the disapproval of the issuance of shares of MKS common stock in
connection with the acquisition. In addition, MKS will notify Emerson when its
board of directors accepts or rejects an acquisition proposal.

     The MKS board of directors has agreed that it will not, unless necessary to
comply with its fiduciary duties and as permitted in the acquisition agreement,
withdraw or modify in a manner adverse to Emerson, its recommendation to the MKS
stockholders to approve the issuance of shares of MKS common stock to Emerson in
connection with the acquisition.

     The acquisition agreement does not prohibit MKS from taking and disclosing
to its stockholders a position with respect to a tender offer contemplated by
Rule 14e-2(a) of the Exchange Act, if the board in its good faith judgment
believes that the failure to disclose such position would be inconsistent with
its obligations under applicable law.

     Delivery of Tax Notices.  Within 30 days prior to the closing of the
acquisition, Emerson will deliver or cause to be delivered to MKS a
certification that Astec America, Inc. is not a foreign person under the
Treasury Regulations of Section 1445 of the Internal Revenue Code. If Emerson
fails to deliver the certification, MKS has the right to withhold from the
amount payable to Emerson all amounts required under Section 1445 of the
Internal Revenue Code.

     License Agreement.  Prior to the closing, Emerson shall cause ENI
Technology, Inc. to execute and deliver a license agreement to Astec
International Limited and Astec America, Inc., each of which are subsidiaries of
Emerson, which will allow such companies to use certain intellectual property
owned by ENI Technology, Inc. which is set forth in the license agreement.

CONDITIONS TO OBLIGATIONS TO EFFECT THE ACQUISITION

     The respective obligations of MKS and Emerson to close the acquisition are
subject to:

       MKS common stock in connection with the acquisition;

       Kong, so designated for resignation or removal by MKS; and

     - MKS shall have received other customary certificates and instruments as
       it reasonably requests in connection with the closing of the acquisition.

     In addition, the obligation of Emerson to effect the acquisition is subject
to the satisfaction or waiver of the following conditions:

       being true and correct as of the date of the acquisition agreement and as

        which case the representation and warranty must be true and correct as
        of such particular date, or

      - any failures to be true and correct could not reasonably be expected to
        have a material adverse effect on MKS and its subsidiaries, taken as a
        whole;

     - MKS shall, or shall have caused its subsidiaries to have, performed or

it will, and will use its reasonable best efforts to cause any affiliate to:

     - make an election under Section 338(g) of the Internal Revenue Code with
       respect to the shares of ENI Hong Kong, ENI Taiwan and ENI China received
       under the terms of the acquisition agreement.

     From and after the time of closing of the acquisition, Emerson and MKS
agreed to cooperate in all reasonable requests in connection with the defense of
or prosecution of any litigation against either party relating to or arising
from the operation of the ENI business prior to or following the closing of the
acquisition.

INDEMNIFICATION

     The acquisition agreement provides that Emerson will indemnify MKS for any
and all damages, subject to the limitations described below, that MKS or an
affiliate of MKS may suffer as a result of:

     - a misrepresentation or breach of a warranty of Emerson contained in the
       acquisition agreement; and

     - any failure to perform any covenant or agreement of Emerson contained in
       the acquisition agreement.

     Except as follows, Emerson's representations and warranties contained in
the acquisition agreement continue in effect until March 31, 2003.
Representations and warranties with respect to Emerson's organization,
qualification and corporate power, ownership of the capital stock of ENI
Technology, Inc., authorization of the transaction and subsidiaries survive
without limitation. Representations and warranties with respect to intellectual
property and environmental matters survive for three years after the closing of
the acquisition and representations and warranties with respect to tax matters
and employee benefits survive until 30 days after the expiration of the
applicable statute of limitations.

                                        38


     The acquisition agreement provides that MKS will indemnify Emerson for any
and all damages, subject to the limitations described below, that Emerson or an
affiliate of Emerson may suffer as a result of:

     - a misrepresentation or breach of warranty of MKS contained in the

       that are assumed by MKS or an affiliate under the terms of the
       acquisition agreement, excluding certain environmental and tax
       liabilities.

     In general, MKS' representations and warranties contained in the
acquisition agreement continue in effect until March 31, 2003. However, the
representations and warranties with respect to MKS' organization and corporate
power, authorization of the transaction and capitalization survive without
limitation.

     Emerson will only be liable for any damages with respect to any individual
claim if the amount of such claim exceeds $40,000 and to the extent the
aggregate amount of damages exceeds $2,000,000. This $2,000,000 threshold for
damages shall not apply if an indemnification claim results from a breach of a
representation and warranty pertaining to Emerson's capitalization, corporate
organization, power to authorize this transaction and Emerson subsidiaries.
Emerson's maximum liability for any and all indemnification claims under the
acquisition agreement is $200,000,000. In addition, if MKS has a claim arising
as a result of a breach of a representation or warranty relating to certain
supply agreements, Emerson will be liable for any damages in excess of $50,000.

     MKS will only be liable for any damages with respect to any individual
claim if the amount of such claim exceeds $40,000 and to the extent the
aggregate amount of the damages exceeds $2,000,000. This $2,000,000 threshold
for damages shall not apply if an indemnification claim results from a breach of
a representation and warranty pertaining to capitalization, corporate
organization and power to authorize this transaction.

     Except for claims based on fraud or under the tax indemnity provisions of
the acquisition agreement, after the closing of the acquisition, the
indemnification rights of MKS and Emerson are the exclusive remedy with respect
to claims resulting from or relating to any misrepresentation, breach of
warranty or failure to perform any covenant or agreement contained in the
acquisition agreement.

     Emerson will indemnify MKS and hold it harmless against the following
taxes:

     - 50% of all taxes other than income taxes relating to the ENI business
       imposed upon ENI Technology, Inc. and ENI Hong Kong and their

TERMINATION; BREAKUP FEES

     The acquisition agreement may be terminated at any time prior to the
closing of the acquisition, as follows:

     - Both MKS and Emerson may terminate the acquisition agreement:

      - by mutual written consent;

      - by giving written notice to the other party if the closing has not
        occurred on or before June 30, 2002 by reason of the failure of any
        condition precedent to the terminating party's closing of the
        acquisition, unless the failure results primarily from a breach by the
        terminating party of any representation, warranty or covenant contained
        in the acquisition agreement; or

      - by giving written notice to the other party at any time after MKS'
        stockholders have voted on, and failed to approve, the issuance of the
        MKS shares of common stock in connection with the acquisition.

     - MKS may terminate the acquisition agreement if:

      - Emerson is in breach of any representation, warranty or covenant
        contained in the acquisition agreement, which breach causes Emerson to
        be unable to "bring down" the representations, warranties and covenants
        at closing, and such breach is not remedied within 20 days of delivery
        of written notice of the breach; or

      - prior to the stockholder vote to approve issuance of MKS shares of
        common stock in connection with the acquisition, the MKS board of
        directors withdraws its recommendation to approve issuance of MKS
        shares of common stock, as permitted by the acquisition agreement.

     - Emerson may terminate the acquisition agreement if:

       - MKS is in breach of any representation, warranty or covenant contained
         in the acquisition agreement, which breach causes MKS to be unable to
         "bring down" the representations, warranties and covenants at closing,
         and such breach is not remedied within 20 days of delivery of written
         notice of the breach;

       - MKS' board of directors withdraws or modifies, or proposes to withdraw
         or modify in a manner adverse to Emerson, its approval for the issuance
         of the MKS shares in connection with the acquisition; or

       - MKS breaches the "non-solicit" covenant in the acquisition agreement
         and an acquisition proposal is announced by a party other than Emerson,
         or any of its affiliates or representatives.

     MKS must pay Emerson a termination fee of $7,000,000 plus all out-of-pocket
expenses, not to exceed $500,000, incurred by Emerson in connection with the
acquisition agreement if:

     - Emerson terminates the acquisition agreement because MKS' board of
       directors withdraws or modifies, or proposes to withdraw or modify in a
       manner adverse to Emerson, its approval for the issuance of the MKS
       shares in connection with the acquisition;

     - Emerson terminates the acquisition agreement because MKS breaches the
       "non-solicit" covenant in the acquisition agreement and an acquisition
       proposal is announced by a party other than Emerson or any of its
       affiliates or representatives;

                                        40


     - MKS terminates the acquisition agreement because, prior to the
       stockholder vote to approve the issuance of MKS shares of common stock in
       connection with the acquisition, its board of directors withdraws its
       recommendation to approve the issuance of MKS' shares of common stock, as
       permitted by the acquisition agreement; or

     - MKS or Emerson terminates the acquisition agreement because the MKS
       stockholders voted on, and failed to approve, the issuance of MKS common
       stock in connection with the acquisition.

AMENDMENT AND WAIVER

     Generally, MKS and Emerson may amend the acquisition agreement at any time
prior to the closing of the acquisition. However, after the stockholders of MKS
approve the issuance of MKS common stock in connection with the acquisition, any
amendment must comply with Massachusetts law. Amendments must be in writing and
signed by all parties and waivers must be in writing and signed by the waiving
party.

                               RELATED AGREEMENTS

VOTING AGREEMENT

     As an inducement to Emerson to enter into the acquisition agreement, on
October 30, 2001, John R. Bertucci, his wife, the trustees of trusts for the
benefit of Mr. and Mrs. Bertucci, and their immediate family, who beneficially
owned an aggregate of 14,966,122 shares of MKS common stock, excluding vested
options, or 39.51% of the outstanding MKS common stock, on October 31, 2001,
entered into a voting agreement with Emerson. Under the terms of the voting
agreement, Mr. and Mrs. Bertucci and the trusts established for the benefit of
the members of the Bertucci family have agreed to vote, and have each granted to
Emerson an irrevocable proxy to vote, their shares of MKS common stock:

     - in favor of the issuance of MKS common stock to Emerson or its designees
       pursuant to the terms of the acquisition agreement; and

     - in favor of the election of, or against the removal of, any person
       nominated by Emerson to serve as a member of the MKS board of directors
       for as long as Emerson is entitled to designate an individual to serve on
       the MKS Board of Directors under the terms of the shareholder agreement,
       as described below.

     In addition, until the issuance of MKS common stock is approved by the
stockholders of MKS, Mr. and Mrs. Bertucci and the Bertucci family trusts have
agreed not to vote their shares of MKS common stock in favor of the approval of
any acquisition proposal or any reorganization, recapitalization, liquidation or
winding up of MKS, or other extraordinary transaction, which would prevent or
delay the acquisition of the ENI business by MKS. The irrevocable proxy
automatically terminates upon the earlier of the closing of the acquisition or
the termination of the voting agreement.

SHAREHOLDER AGREEMENT

     At the closing of the acquisition, the parties will execute a shareholder
agreement. Under the terms of this agreement, Emerson has the right to nominate
one person to serve as a member of the MKS board of directors effective as of
the closing of the acquisition. The MKS board of directors has agreed to
nominate Mr. James G. Berges, or other designee nominated by Emerson and
reasonably acceptable to MKS, for election to the board at all meetings of
stockholders at which MKS stockholders will vote on the election of directors
following the closing of the acquisition. MKS' obligation to nominate Mr.
Berges, or other designee nominated by Emerson, will terminate when Emerson and
its subsidiaries cease to beneficially own at least 12.5% of the outstanding MKS
common stock.

     In addition, for a period of one year after the closing of the acquisition,
Emerson and each of its subsidiaries has agreed not to, directly or indirectly,
sell, transfer, pledge, contract to sell, sell any option or

                                        41


contract to purchase, purchase any option or contract to sell, grant any option,
right or warrant to purchase, transfer the economic risk of ownership or
otherwise dispose of any shares of MKS common stock, unless MKS during such one
year period makes a public announcement of, or effects a transaction which would
result in the issuance or sale of shares of MKS common stock that would possibly
result in reducing Emerson's ownership to less than less than 20% of the
outstanding MKS common stock. In such an event, the lockup period set forth
above would end on the later of the date which is six months after the closing
of the acquisition or the earlier of the public announcement or the closing of
such dilutive transaction.

     In addition, for a period of three years after the closing of the
acquisition, Emerson and its subsidiaries shall not, and shall not assist anyone
else to:

     - acquire or take any action to acquire any additional shares of MKS common
       stock or property of MKS (other than property acquired in the ordinary
       course of business), except for shares or property acquired due to a
       merger, consolidation or similar transaction involving MKS or a stock
       split, or other similar adjustment affecting the MKS common stock or upon
       the prior approval of a majority of the board of directors, excluding any
       director nominated by Emerson;

     - solicit a proxy or become a participant in a proxy solicitation in
       opposition to any matter which has been recommended by a majority of the
       members of the board of directors or propose or otherwise solicit
       stockholders of MKS for approval of any stockholder proposals, or
       otherwise seek to influence the management of MKS; or

     - take any action to seek control of MKS.

     In addition, Emerson shall not, and shall not permit its subsidiaries to,
transfer any of the shares of MKS common stock received pursuant to the
acquisition agreement to any person or entity that competes in any of the same
principal markets as MKS or any person or entity (other than institutional
purchasers, as defined in the shareholder agreement) which Emerson knows that,
as a result of such transaction, would own more than 5% of the then outstanding
common stock of MKS. These restriction do not apply to any block trade crossed
through the Nasdaq National Market unless the broker or market-maker effecting
such sale has actual knowledge that as a result of such sale the eventual buyer
would own 5% of the outstanding common stock of MKS.

     None of the foregoing restrictions on the transfer or disposition of MKS
common stock by Emerson shall apply to:

     - any transfer to Emerson or its subsidiaries; or

     - any transfer under a tender or exchange offer made by MKS or recommended
       by the MKS board of directors to its stockholders.

     In addition, under the shareholder agreement, Emerson is entitled to
require MKS to register the shares of MKS common stock issued in connection with
the acquisition agreement under the Securities Act. Under the agreement, Emerson
may, on up to three occasions, require MKS to register its shares of common
stock for resale under the Securities Act in an underwritten offering. MKS will
not, subject to certain exceptions, be required to register more than four
million shares prior to the date which is one year after the expiration of the
lock-up period, eight million shares prior to the date which is two years after
the expiration of the lock-up period, and twelve million shares prior to the
time which is three years after the expiration of the lock-up period.

     In addition, under the agreement, if MKS proposes to register any of its
common stock under the Securities Act, either for its account or for the account
of other security holders, Emerson is entitled to notice of the registration and
to include its, and its subsidiaries, shares of MKS common stock in the
registration. The registration rights held by Emerson are subject to conditions
and limitations, including the right of the underwriters of an offering to limit
the number of shares included in such registration and MKS' right not to effect
a requested registration if it has a bona fide intention to file a registration

                                        42


statement for an underwritten public offering within 60 days of receiving a
registration request. MKS is responsible for paying the expenses of any such
registration.

     The form of Shareholder Agreement is attached as Exhibit A to Annex A
hereto.

EMPLOYMENT AGREEMENTS

     In connection with the acquisition, MKS entered into an employment
agreement with each of John G. Stratakos, G.W. Wong, Stephen R. Phillips, George
A. Altimonda, David W. Steblein, Edward L. Maier, Robert J. Lelio, Anthony
Harris, Anthony Keane and Jeff Sellers, all of whom are currently employees of
the ENI business. Additionally, MKS will enter into an employment agreement with
Hisami Nishio, who is also currently an employee of the ENI business. The
employment agreements take effect upon the closing of the acquisition; however,
in the event of termination of the acquisition agreement or in the event the
acquisition does not close on or before June 30, 2002, the employment agreements
shall automatically terminate.

SERVICES AGREEMENTS

     In order to enable MKS to operate the ENI business in an effective manner
after the closing of the acquisition, at the closing MKS and Emerson will enter,
prior to the closing of the acquisition, into a services agreement for the
operation of the China division of the ENI business and another services
agreement for the remainder of the ENI business pursuant to which Emerson will
provide services to the ENI business as set forth in the agreements. Emerson
will provide services to MKS at commercially acceptable quality levels, which
will be substantially similar in scope, quality and nature to those services
provided to, or on behalf of, the ENI business immediately prior to
effectiveness of the agreement. Additionally, under the services agreement for
the China division of the ENI business, Emerson will make available to MKS the
portion of Emerson's Shenzhen City, China facility that is currently occupied by
the China division of the ENI business.

     With respect to the provision of services, Emerson will calculate the costs
of services to MKS based on either a customary billing method or the
pass-through billing method. The method for calculating the costs of services by
the customary billing method will be the same as the method used to calculate
the cost of comparable services charged to other businesses operated by Emerson.
Emerson will provide MKS with at least 60 days notice prior to making any change
in the customary billing charges that would result in an increase in charges to
MKS. The costs of services determined by the pass-through billing method will be
equal to the third-party costs and expenses incurred by Emerson on behalf of
MKS.

     Prior to the end of each year, Emerson will prepare an updated schedule of
services to be provided to MKS under the agreement, along with any proposed
changes in billing methodology and, to the extent available, the estimated cost
of services for the next fiscal year. If requested by MKS, Emerson may provide
additional services to MKS on mutually agreed upon prices and terms.

     Both Emerson and MKS will indemnify each other and hold the other and its
affiliates harmless against any damages, costs and expenses (including
reasonable attorneys' fees) arising from its gross negligence or intentional
misconduct in connection with any services, action or inaction or material
breach of any of its obligations under the agreement. Additionally, MKS will
indemnify and hold Emerson and its affiliates harmless against any damages,
costs and expenses arising from any liabilities, costs, expenses or damages
resulting from any damage caused by MKS to the facility occupied by the China
division of the ENI business, net of any insurance or other recoveries received
by Emerson with respect thereto.

     The services agreement for the China division of the ENI business will be
in effect from the date of the agreement until 2004, unless earlier terminated.
The services agreement for the rest of the ENI business will be in effect from
the date of the agreement until 90 days after the closing of the acquisition,
unless earlier terminated. The services agreements may be terminated upon
material breach not cured within 60 days of notice or by MKS at any time upon 60
days prior written notice to Emerson.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
      OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS OF THE ENI BUSINESS

     The following discussion and analysis of the financial condition and
results of operations of the ENI business should be read in conjunction with ENI
business' combined financial statements and the notes to those statements
included elsewhere in this proxy statement.

     The following discussion contains forward-looking statements. The
forward-looking statements reflect the views of the ENI business with respect to
future events and financial performance and are subject to risks, uncertainties
and assumptions. The following discussion does not give effect to the
acquisition or any changes in the ENI business that MKS may effect following
closing. The information set forth in this section was prepared by the ENI
business and any reference to "we" and "our" in this section refers to the ENI
business only.

     The ENI business designs, manufactures, sells and supports high precision,
high power electrical conversion and control systems in the United States,
Europe and Asia. These systems are primarily used in thin-film processing
equipment in the global semiconductor, data storage, FPD, and industrial
coatings markets. The ENI business' products are integrated into the
manufacturing tools of these industries to produce finished goods which include
semiconductor integrated circuits, computer hard disks, FPDs, compact discs, and
digital video discs. The ENI business' products and systems refine, modify and
control the raw electrical power generated by a utility and convert it into
reliable solid state power that can be readily used by production tools for
advanced thin film processing applications. The ENI business is comprised of
certain worldwide businesses of Emerson, which are either divisions of U.S.
corporations or foreign corporations, all of which are wholly-owned by Emerson.

COMPARISON OF NINE MONTHS ENDED JUNE 2001 AND JUNE 2000

RESULTS OF OPERATIONS

     Net Sales.  Net sales increased 25.9% to $96.5 million for the nine months
ended June 30, 2001 from $76.6 million for the nine months ended June 30, 2000.
International net sales were approximately $37.1 million for the nine months
ended June 30, 2001 or 38.5% of net sales and $29.5 million for the same period
of 2000 or 38.6% of net sales. The increase in net sales was due to the growth
in demand for semiconductors in 2001 as compared with 2000 resulting in strong
demand for the ENI business' products from semiconductor capital equipment
manufacturers. Strong market conditions prevailed through the March 2001 quarter
end, subsequently declining in the June 2001 quarter due to weakness in the
overall demand for semiconductors and other electronic devices. The
semiconductor equipment market declined further in the September 2001 quarter,
in which ENI's net sales were $12.5 million, and is expected to remain weak in
the December 2001 quarter. Net sales to semiconductor capital equipment
manufacturers and semiconductor device manufacturers were 92.0% of total net
sales for the nine months ended June 30, 2001 and 2000.

     Gross Profit.  Gross profit as a percentage of net sales decreased to 40.9%
for the nine months ended June 30, 2001 from 49.6% for the nine months ended
June 30, 2000. The decrease was primarily due to lower absorption of
manufacturing overhead costs, unfavorable exchange rates and increased warranty
costs. Additionally, gross margins were negatively effected by a $1.8 million
provision for obsolete and excess inventory and a $1.9 million provision for
inventory purchase commitments in the June 2001 quarter. These provisions were
significantly higher than normal and were primarily caused by a sharp reduction
in demand, including reduced demand for products used on older semiconductor
fabrication tools. The weakening market conditions during the quarter ended
September 30, 2001 resulted in a 12.4% gross profit. This was due primarily to
the impact of lower production volumes on absorption of manufacturing overhead
costs combined with incremental provisions for excess inventory and warranty
costs.

     Research and Development.  Research and development expense increased 35.8%
to $11.1 million or 11.5% of net sales for the nine months ended June 30, 2001
from $8.2 million or 10.7% of net sales for the

                                        45


nine months ended June 30, 2000. The increase was primarily due to increased
employment levels and spending for project materials to keep pace with
increasing demand for our participation in customers' new tool designs.

     Selling.  Selling expenses decreased 3.1% to $6.0 million or 6.3% of net
sales for the nine months ended June 30, 2001 from $6.2 million or 8.1% of net
sales for the nine months ended June 30, 2000. This change was primarily a
result of lower compensation costs and reductions in advertising and travel
expenses.

     General and Administrative.  General and administrative expense increased
36.9% to $4.9 million or 5.1% of net sales for the nine months ended June 30,
2001 from $3.6 million or 4.7% of net sales for the nine months ended June 30,
2000. The increase was primarily resulting from increased employment levels and
non-recurring systems consulting costs.

     Amortization of Goodwill.  Amortization of goodwill of $0.9 million or 1.0%
and 1.2% of net sales, respectively for the nine months ended June 30, 2001 and
2000, respectively, represents the amortization of goodwill related to the
acquisition of the ENI business by Emerson, which was completed in fiscal 1999
with Emerson increasing its ownership in the ENI business from 51% to 100%.

     Litigation Expenses.  The litigation expenses were associated with a patent
infringement lawsuit which the ENI business settled in March 2001. Significant
non-recurring legal costs were incurred in 2000 associated with this lawsuit.

     Interest Income (Expense), Net.  The ENI business incurred net interest
expense of $0.2 million and $0.1 million for the nine months ended June 30, 2001
and 2000, respectively, primarily resulting from its IDRB Lease.

     Provision for Income Taxes.  The effective tax rate for the nine months
ended June 30, 2001 and 2000 was 39.5% and 39.2%, respectively. Substantially
all of the ENI business' operations are included in Emerson's U.S. federal,
state or foreign income tax returns filed by Emerson legal entities. However,
for purposes of preparing the financial statements of the ENI business, the tax
provision has been determined as if the ENI business filed separate tax returns
in each tax jurisdiction that it operates.

LIQUIDITY AND CAPITAL RESOURCES

     The ENI business has financed its operations and capital requirements
through a combination of cash provided by operations, long-term real estate
financing and capital contributions from Emerson.

     Working capital was $22.9 million as of June 30, 2001, an increase of $13.0
million from September 30, 2000. Operations provided cash of $10.8 million for
the nine months ended June 30, 2001. This cash flow was impacted by net income,
depreciation and amortization and reductions in the levels of accounts
receivable, accounts payable and inventory. The reductions in accounts
receivable, accounts payable and inventory were resulting from the decline in
the June 2001 quarter level of business relative to the September 2000 quarter,
reflecting the weakness in the overall demand for semiconductors and other
electronic devices. Investing activities utilized cash of $4.6 million for the
nine months ended June 30, 2001, primarily from the construction of a 40,000
square foot Research and Development facility at its Rochester, New York
facility. Financing activities utilized cash of $5.4 million, primarily from
distributions to Emerson.

COMPARISON OF FISCAL YEAR ENDED SEPTEMBER 2000 AND SEPTEMBER 1999

     Net Sales.  Net sales increased 89.1% to $109.5 million for the year ended
September 30, 2000 from $57.9 million for the year ended September 30, 1999.
International net sales were approximately $40.8 million or 37.3% of net sales
in fiscal 2000 and $30 million or 51.8% of net sales in fiscal 1999. The
increase in net sales was due to the growth in demand for semiconductors in
fiscal 2000 as compared with fiscal 1999 that resulted in strong demand for the
ENI business' products from semiconductor capital equipment manufacturers.
Accordingly, net sales to semiconductor capital equipment manufacturers and

                                        46


semiconductor device manufacturers increased to 94% of total net sales in fiscal
2000 from 84% of total net sales in fiscal 1999.

     Gross Profit.  Gross profit as a percentage of net sales increased to 48.3%
for fiscal 2000 from 43.9% for fiscal 1999. The increase was primarily due to
improved leverage of fixed manufacturing overhead costs on the significant
increase in sales volumes, favorable exchange rates and cost savings achieved
from increased production in the ENI business' China manufacturing facility.

     Research and Development.  Research and development expense increased 57.6%
to $11.5 million or 10.5% of net sales for fiscal 2000 from $7.3 million or
12.6% of net sales for fiscal 1999. The increase was primarily due to increased
compensation expense and spending for project materials to develop new products
for the semiconductor capital equipment market.

     Selling.  Selling expenses increased 38.1% to $8.7 million or 8.0% of net
sales for fiscal 2000 from $6.3 million or 10.9% of net sales for fiscal 1999.
This increase was primarily a result of spending increases for additional sales
personnel and increases in advertising and travel expenses.

     General and Administrative.  General and administrative expense increased
72.2% to $5.3 million or 4.9% of net sales for fiscal 2000 from $3.1 million or
5.3% of net sales for fiscal 1999. The increase was primarily resulting from
increased employment levels, depreciation expense, normal management charges
from Emerson and professional fees.

     Amortization of Goodwill.  Amortization of goodwill was $1.3 million or
1.1% of net sales for fiscal 2000 and $1.1 million or 1.9% of net sales for
fiscal 1999 and represents the amortization of goodwill related to the
acquisition of the ENI business by Emerson, which was completed in fiscal 1999
with Emerson increasing its ownership in the ENI business from 51% to 100%.

     Litigation Expenses.  Litigation expenses were associated with a patent
infringement lawsuit which the ENI business settled in March 2001. The
settlement amount of $1.5 million was accrued in the fiscal 2000 results.

     Interest Income (Expense), Net.  Net interest expense amounted to $0.2
million for fiscal 2000 and 1999, primarily resulting from its IDRB Lease.

     Provision for Income Taxes.  The effective tax rates for fiscal 2000 and
1999 were 38.4% and 40.6%, respectively. Substantially all of the ENI business'
operations are included in Emerson's U.S. federal, state or foreign income tax
returns filed by Emerson legal entities. However, for purposes of preparing the
financial statements of the ENI business, the tax provision has been determined
as if the ENI business filed separate tax returns in each tax jurisdiction in
which it operates.

LIQUIDITY AND CAPITAL RESOURCES

     The Company has financed its operations and capital requirements through a
combination of cash provided by operations, long term real estate financing and
capital infusions from Emerson.

     Working capital was $9.9 million as of September 30, 2000, a decrease of
$3.0 million from September 30, 1999. Operations provided cash of $8.2 million
and $7.5 million for fiscal 2000 and 1999, respectively. This cash flow was
impacted by net profit, depreciation and amortization and increases in the
levels of inventory, accounts receivable, accounts payable, income taxes payable
and accrued expenses. The increases in inventory, accounts receivable, accounts
payable and accrued expenses resulted from the significant increase in business
levels throughout fiscal 2000, reflecting growing strength in the overall demand
for semiconductors and other electronic devices. Investing activities utilized
cash of $6.9 million and $1.0 million for fiscal 2000 and 1999, respectively for
the purchase of property, plant, and equipment. Financing activities provided
cash of $1.2 million in fiscal 2000 consisting of capital contributions from
Emerson and utilized cash of $9.4 million in fiscal 1999 consisting of
distributions to Emerson.

COMPARISON OF YEAR ENDED SEPTEMBER 1999 AND SEPTEMBER 1998

RESULTS OF OPERATIONS

     Net Sales.  Net sales decreased 3.6% to $57.9 million for the year ended
September 30, 1999 from $60.0 million for the year ended September 30, 1998.
International net sales were approximately $30 million or 51.8% of net sales in
fiscal 1999 and $26.3 million or 43.8% of net sales in fiscal 1998. The decrease
in net sales was due to the reduction in demand for semiconductors in fiscal
1999 as compared with fiscal 1998 that resulted in lower demand for the ENI
business' products from semiconductor capital equipment manufacturers. Net sales
to semiconductor capital equipment manufacturers and semiconductor device
manufacturers were 84% and 81% of total net sales for fiscal 1999 and 1998,
respectively.

     Gross Profit.  Gross profit as a percentage of net sales increased to 43.9%
for fiscal 1999 from 43.1% for fiscal 1998. The increase was primarily due to
the impact of favorable exchange rates, net of unfavorable changes in the mix of
product sold.

     Research and Development.  Research and development expense decreased 5.9%
to $7.3 million or 12.6% of net sales for fiscal 1999 from $7.7 million or 12.9%
of net sales for fiscal 1998. The decrease was primarily due to lower
compensation expense and spending for project materials resulting from
forcecount reductions and other cost reduction measures implemented during
fiscal 1998 and early fiscal 1999.

     Selling.  Selling expenses decreased 4.2% to $6.3 million or 10.9% of net
sales for fiscal 1999 from $6.6 million or 11.0% of net sales for fiscal 1998.
This reduction was primarily resulting from forcecount reductions and reductions
in advertising costs.

     General and Administrative.  General and administrative expense decreased
1.8% to $3.1 million or 5.3% of net sales for fiscal 1999 from $3.1 million or
5.2% of net sales for fiscal 1998. The decrease was primarily resulting from
reductions in discretionary spending related to recruitment and
telecommunications costs.

     Amortization of Goodwill.  Amortization of goodwill was $1.1 million or
1.9% of net sales for fiscal 1999 and $0.4 million or 0.7% of net sales for
fiscal 1998. This represents the amortization of goodwill related to the
acquisition of the ENI business by Emerson, which was completed in fiscal 1999
with Emerson increasing its ownership in the ENI business from 51% to 100%.

     Litigation Expenses.  Litigation expenses were associated with a patent
infringement lawsuit which the ENI business settled in March 2001.

     Interest Income (Expense), Net.  Net interest expense amounted to $0.2
million for fiscal 1999 and 1998, primarily resulting from its IDRB Lease.

     Provision for Income Taxes.  The effective tax rates for fiscal 1999 and
1998 were 40.6% and 38.1%, respectively. Substantially all of the ENI business'
operations are included in Emerson's U.S. federal, state or foreign income tax
returns filed by Emerson legal entities. However, for purposes of preparing the

         UNAUDITED PRO FORMA COMBINED CONSOLIDATED FINANCIAL STATEMENTS

     The following unaudited pro forma combined consolidated financial
statements present the effect of the pending acquisition of the ENI business by
MKS Instruments, Inc. to be accounted for as a purchase. The unaudited pro forma
combined consolidated balance sheet presents the combined consolidated financial
position of MKS and the ENI business as of September 30, 2001 assuming that the
proposed acquisition had occurred as of that date. Such pro forma information is
based upon the historical consolidated balance sheet of MKS as of September 30,
2001, and the historical combined balance sheet of the ENI business as of June
30, 2001. The unaudited pro forma combined consolidated statement of operations
for the year ended December 31, 2000 gives effect to the pending acquisition by
MKS of the ENI business as if the acquisition had occurred at the beginning of
the period presented and includes the ENI business' combined statement of
operations for the year ended September 30, 2000 with that of MKS' consolidated
statement of operations for the year ended December 31, 2000. The unaudited pro
forma combined consolidated statement of operations for the nine months ended
September 30, 2001 includes MKS' consolidated statement of operations for the
nine months ended September 30, 2001 with that of the ENI business' combined
statement of operations for the nine months ended June 30, 2001.

     Unaudited pro forma combined consolidated financial information is
presented for illustrative purposes only and is not necessarily indicative of
the financial position or results of operations that would have actually been
reported had the acquisition occurred at the beginning of the periods presented,
nor is it necessarily indicative of future financial position or results of
operations. These unaudited pro forma combined consolidated financial statements
are based upon the respective historical financial statements of MKS and the ENI
business, as adjusted, and do not incorporate, nor do they assume, any benefits
from cost savings or synergies of operations of the combined company.

     The allocation of the purchase price will be finalized following the
closing of the acquisition and finalization of appraisals to determine the fair
value of tangible and identifiable intangible assets. Based on an analysis of
fair market value, the excess of the purchase price over the fair value of net
tangible and intangible assets on the balance sheet of the ENI business will be
allocated to goodwill. MKS is currently gathering the data necessary to
determine the fair market value of identifiable intangible assets. Because the
valuation analysis has not been completed, the actual amount of goodwill and
identifiable intangible assets, and the related average useful life, could vary
from these assumptions.

    NOTES TO UNAUDITED PRO FORMA COMBINED CONSOLIDATED FINANCIAL STATEMENTS

                             (TABLES IN THOUSANDS)

1.  BASIS OF PRESENTATION

     On October 30, 2001, MKS Instruments, Inc. entered into a definitive
agreement to acquire the ENI business in a transaction to be accounted for as a
purchase. Under the terms of the agreement, MKS will issue 12 million shares of
common stock to Emerson in exchange for the ENI business.

     The estimated value of the MKS common stock is approximately $21.7720 per
share based on the average closing price of MKS' common stock for the five-day
period including the date of the announcement of the signing of the merger
agreement and the two days preceding and succeeding such date.

     The purchase consideration is estimated as follows:


                                                            
Common stock................................................   $261,264
Estimated transaction expenses..............................      4,150
                                                               --------
                                                               $265,414
                                                               ========


     The preliminary allocation of the purchase price using balances as of June
30, 2001 is summarized below:


                                                            
Accounts Receivable.........................................   $ 12,615
Inventories.................................................     26,131
Property and equipment......................................     20,376
Developed technology........................................     30,500
Patents.....................................................      4,100
In-process research and development.........................      7,300
Goodwill....................................................    203,292
Other net liabilities.......................................    (25,811)
Deferred tax liability......................................    (13,089)
                                                               --------
                                                               $265,414
                                                               ========


     The actual purchase price allocation is also dependent upon the fair values
of the acquired assets and assumed liabilities as of the acquisition date and
the finalization of the preliminary valuation report.

     For pro forma purposes, the long-term debt has been reflected at the ENI
business' June 30, 2001 carrying value, pending a determination of its estimated
fair value. The $7.3 million amount allocated to in-process research and
development represents the purchased in-process technology for projects that had
not yet reached technological feasibility and had no future alternative use.
Based on preliminary assessments, the value of these projects was determined by
estimating the resulting net cash flows from the sale of the products resulting
from the completion of the projects, reduced by the portion of the revenue
attributable to developed technology and the percentage of completion of the
project. The resulting cash flows were then discounted back to their present
value at appropriate discount rates.

     The nature of the efforts to develop the purchased in-process research and
development into commercially viable products principally relates to the
completion of planning, designing, prototyping and testing activities that are
necessary to establish that the product can be produced to meet its design
specification including function, features and technical performance
requirements. The resulting net cash flows from such products are based on
estimates of revenue, cost of revenue, research and development costs, sales and
marketing costs, and income taxes from such projects.

          NOTES TO UNAUDITED PRO FORMA COMBINED CONSOLIDATED FINANCIAL
                           STATEMENTS -- (CONTINUED)

     The amounts allocated to in-process research and development will be
charged to the statement of operations in the period the acquisition is
consummated.

     Goodwill represents the excess of purchase price over the fair value of the
underlying net identifiable assets. Goodwill is not amortized in accordance with
Statement of Financial Accounting Standards No. 142, "Goodwill and Other
Intangible Assets."

     The deferred tax liability relates to differences between book and tax
bases of acquired assets and liabilities assumed.

2.  PRO FORMA ADJUSTMENTS


  
    A    Reflects the elimination of certain excluded assets and
         liabilities under the terms of the acquisition.

    B    Reflects the acquisition of the ENI business based on the
         preliminary purchase price described in Note 1.

    C    Reflects the elimination of the ENI business' historical
         patent amortization and accumulated net balance.

    D    Reflects amortization of developed technology and patents
         over their estimated useful lives of five and eight years,
         respectively, as if the acquisition occurred at the
         beginning of each period presented. The $7.3 million amount
         allocated to in-process research and development has not
         been included in the unaudited pro forma combined
         consolidated statement of operations as it is nonrecurring,
         but is included as a reduction in retained earnings in the
         unaudited combined consolidated balance sheet. This amount
         will be expensed in the period the acquisition is
         consummated.

    E    Reflects the elimination of historical divisional control
         amounts of the ENI business.

    F    Additional depreciation of the increase in fair value of
         property and equipment.

    G    Reflects the elimination of the ENI business' historical
         amortization of goodwill.

    H    Represents pro forma combined consolidated provision for
         income taxes at a rate of 37.3% and 18.0% of income before
         income taxes for the year ended December 31, 2000 and the
         nine months ended September 30, 2001, respectively, based on
         MKS' historical rates for the periods presented.

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors
Emerson Electric Co.:

     We have audited the accompanying combined balance sheets of ENI as of
September 30, 2000 and 1999, and the related combined statements of income,
divisional control and comprehensive income and cash flows for each of the years
in the three-year period ended September 30, 2000. These combined financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these combined 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 combined
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the combined financial statements. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall combined financial statement presentation. We believe
that our audits provide a reasonable basis for our opinion.

     In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the financial position of ENI as of September
30, 2000 and 1999, and the results of its operations and its cash flows for each
of the years in the three-year period ended September 30, 2000 in conformity
with accounting principles generally accepted in the United States of America.

                     NOTES TO COMBINED FINANCIAL STATEMENTS
                       SEPTEMBER 30, 2000, 1999 AND 1998
        (ALL INFORMATION SUBSEQUENT TO SEPTEMBER 30, 2000 IS UNAUDITED)
                                 (IN THOUSANDS)

(1) BASIS OF PRESENTATION

     The accompanying combined financial statements present the financial
position, results of operations and cash flows of ENI. ENI is comprised of
certain worldwide businesses of Emerson Electric Co. ("Emerson"), which are
either divisions of U.S. corporations or foreign corporations, all of which are
wholly-owned by Emerson. Emerson acquired these businesses through a series of
transactions beginning in 1989 and concluding in 1999. The purchases were
accounted for as a step acquisition with the excess of the purchase price paid
over the fair value of the identifiable assets accounted for as goodwill by ENI.

     The combined financial statements include the accounts of ENI and its
Operating Group. The Operating Group includes operating divisions or
subsidiaries whose activities are managed and directed by ENI but which are
owned by other statutory entities within Emerson. These include the following:
ENI Division of Astec America, Inc. ("ENI-AAI"), ENI Technology, Inc.
("ENI-Tech"), ENI Japan, Ltd. ("ENI-Japan"), ENI Germany Division of Astec
Germany GMbH ("ENI-Germany"), ENI Taiwan, Ltd. ("ENI-Taiwan"), ENI Europe
Division of Astec Europe, Ltd. ("ENI-Europe"), ENI Korea Division of Emerson
Korea, Ltd. ("ENI-Korea"), ENI Asia Division of Astec International, Ltd. ("ENI-
Asia"), ENI HK Manufacturing Division of Astec Custom Power (HK), Ltd. ("ENI-HK
Mfg") and ENI China Division of Astec Power Supply (Shenzhen) Co., Ltd.
("ENI-China").

     It is Emerson's corporate policy to charge its divisions for all
specifically identifiable corporate related costs, plus an expense allocation
for general corporate services. The accompanying combined financial statements
reflect these expense allocations. These allocations relate primarily to
treasury, tax, legal, employee benefits, insurance, facility usage, and other
administrative services performed on behalf of all divisions and are based upon
a percentage of revenue which was approximately 1% each of the years in the
three year period ended September 30, 2000, 1999 and 1998. This method of
allocation is consistently applied by Emerson to all its operating groups.
General costs allocated for such services have been reflected in ENI's results
of operations and amounted to $1,172, $566 and $603 for the years ended
September 30, 2000, 1999 and 1998, respectively. Because certain allocations may
not be the same as those that would result from transactions among unrelated
parties, the accompanying financial statements may not necessarily be indicative
of the financial position, results of operations and cash flows if ENI were an
independent entity.

     Corporate related costs allocated and reported in ENI's results of
operations for the nine-month periods ending June 30, 2001 and 2000 were $1,144
(unaudited) and $846 (unaudited), respectively.

(2) DESCRIPTION OF BUSINESS

     ENI designs, manufactures, sells and supports high precision, high power
electrical conversion and control systems in the United States, Europe and Asia.
These systems are primarily used in thin film processing equipment in the global
semiconductor, data storage, flat panel display ("FPD") and industrial coatings
markets. The Company's products are integrated into the manufacturing tools of
these industries to produce finished goods which include semiconductor
integrated circuits ("ICs"), computer hard disks, FPDs, compact discs ("CDs"),
and digital video discs ("DVDs"). The Company's products and systems refine,
modify and control the raw electrical power generated by a utility and convert
it into reliable solid state power that can be readily used by production tools
for advanced thin film processing applications. The Company's website is
www.enipower.com.

(3) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  ACCOUNTING FOR DERIVATIVES (UNAUDITED)

     On October 1, 2000, ENI adopted SFAS No. 133, Accounting for Derivative
Instruments and Hedging Activities, as amended, which requires companies to
carry all derivatives on the balance sheet at fair value. The accounting for
changes in the fair value of a derivative instrument depends on whether it has
been designated and qualifies as part of a hedging relationship and, if so, the
reason for holding it.

     For the nine months ended June 30, 2001, ENI's exposure to derivatives is
limited to foreign currency hedging agreements. In order to provide for foreign
currency risk protection on forecasted sales of product to ENI-Japan, the
Company from time to time enters into foreign currency forward contracts to
effectively exchange currency denominated in Yen for U.S. dollars. Foreign
currency forward contracts generally mature within one year.

     The effective portion of the gain or loss, net of tax, on a cash flow hedge
is reported in other comprehensive income and reclassified into earnings in the
same period or periods during which the hedged transaction affects earnings, and
the ineffective portion is reported immediately in earnings. There was no
ineffectiveness through June 30 of fiscal 2001.

     Activity in the other comprehensive income related to derivatives held by
ENI during the period from October 1, 2000 through June 30, 2001 is summarized
below:

  USE OF ESTIMATES

     The preparation of 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 and disclosure of contingent assets and liabilities at
year end and the reported amounts of revenues and expenses during the reporting
period. Certain significant estimates are disclosed throughout this report.
Actual results could differ from these estimates.

     ENI is subject to certain risks similar to other companies in its industry.
These risks include the volatility of the semiconductor and semiconductor
capital equipment industries, customer concentration within the markets which
ENI serves, manufacturing facilities risks, management of growth, supply
constraints and dependencies, rapid technological changes, competition,
international sales risks, the Asian financial markets, and governmental
regulations. A significant change in any of these risk factors could have a
material impact on ENI.

  REVENUE RECOGNITION

     Typically ENI recognizes revenue upon shipment. However, ENI does ship
products to certain customers on a trial basis for periods of 30 to 60 days. The
corresponding revenue is recognized after the customer has agreed to purchase
the goods as evidenced by receipt of a signed purchase order from the customer.
ENI records cash advances from customers that have not been shipped products as
of year end as liabilities under deposits received from customers for product
sales. Revenue is recognized upon subsequent shipment to the customer location.

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

  COMBINATION

     The combined financial statements include the accounts of ENI and all
entities or divisions within the ENI group. All significant intercompany
accounts and transactions have been eliminated in combination.

  FOREIGN CURRENCIES

     The functional currency for the ENI's foreign operations is the applicable
local currency. ENI records a translation adjustment from translation of the
combined financial statements of its foreign units which is recorded in
accumulated other comprehensive income (loss). Net assets are translated at
current exchange rates as of the balance sheet date, and income and expense
items are translated at the average exchange rate for the year.

     ENI recognizes gains or losses on all foreign currency transactions, other
than intercompany transactions that are of a long-term nature. ENI recognized
income (losses) on foreign currency transactions of $(124), $11 and $9 for the
years ended September 30, 2000, 1999 and 1998, respectively.

     ENI recognized losses on foreign currency translations of $75 (unaudited)
and $86 (unaudited) for the nine month periods ending June 30, 2001 and 2000,
respectively.

  FAIR VALUE OF FINANCIAL INSTRUMENTS

     The fair value of ENI's cash, accounts receivable, accounts payable,
accrued expenses and long-term debt approximates their respective carrying
amounts.

  CASH AND CASH EQUIVALENTS

     For cash flow purposes, ENI considers all cash and highly liquid
investments with original issue maturities of 90 days or less to be cash and
cash equivalents.

  CONCENTRATIONS OF RISK

     Financial instruments, which potentially subject ENI to concentrations of
credit risk, consist principally of cash and trade accounts receivable. ENI's
cash is placed with high credit quality financial institutions. Concentrations
of credit risk with respect to trade accounts receivable are concentrated among
a small number of customers, the majority of which are in the semiconductor
capital equipment industry. ENI's foreign subsidiaries receivables are primarily
denominated in currencies other than the U.S. dollar. ENI performs ongoing
credit evaluations of its customers, and generally does not require collateral
pledges, as many of its customers are large, well-established companies. ENI
maintains reserves for potential credit losses but historically has not
experienced any significant losses. ENI does maintain significant concentrations
of credit risk with certain major customers (see note 14).

  INVENTORIES

     Inventories include costs of materials, direct labor and manufacturing
overhead. Inventories are valued at the lower of cost (first-in, first-out
basis), or market.

  COMPREHENSIVE INCOME (LOSS)

     SFAS No. 130, Reporting Comprehensive Income, established rules for the
reporting of comprehensive income and its components. Comprehensive income for
the Company consists of net income and foreign currency translation adjustments
and is presented in the combined statements of divisional control and
comprehensive income.

                                      ENI
             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

  GOODWILL AND INTANGIBLES

     Prior to fiscal year 1999, Emerson owned 51% of ENI through its ownership
of Astec (BSR) Plc. ("Astec"). Emerson recorded goodwill relating to the
original ownership of ENI and continued to record incremental goodwill in 1999
with its increased ownership through a step acquisition during fiscal year 1999.
The incremental goodwill recorded through the step acquisition was pushed down
to ENI from Emerson in the amount of $32,947 in 1999. All of the goodwill
included in the accompanying combined balance sheets resulted from Emerson's
acquisition of Astec.

     Goodwill is amortized on the straight-line method over 40 years, based on
the estimated economic life. The carrying value of goodwill is reviewed for
recoverability based on the undiscounted cash flows of the businesses acquired
over the remaining amortization period. Should the review indicate that goodwill
is not recoverable, the company's carrying value of the goodwill would be
reduced by the estimated shortfall of the cash flows. In addition, the company
assesses long-lived assets for impairment under Financial Accounting Standards
Board's (FASB) Statement of Financial Accounting Standards (SFAS) No. 121,
Accounting for the Impairment of Long-Lived Assets to be Disposed Of. Under
these rules, goodwill associated with assets acquired in a purchase business
combination is included in impairment evaluations when events or circumstances
exist that indicate the carrying amount of those assets may not be recoverable.
No reduction of goodwill for impairment was necessary in 2001 (unaudited), 2000,
1999 or 1998.

     Certain other assets consist of unamortized patent and bond issue costs.
Patents are being amortized over a useful life of 3 years while capitalized bond
costs are being amortized over the life of the bond using the effective interest
method. Amortization expense was $165, $115 and $112 in the years ended
September 30, 2000, 1999 and 1998, respectively.

  DEMONSTRATION EQUIPMENT

     Demonstration equipment represents manufactured products utilized for sales
demonstration and evaluation purposes. The Company also utilizes this equipment
in its customer service function as replacement and loaner equipment to existing
customers.

     The Company depreciates the equipment based on its estimated useful life in
the sales and customer service functions. The depreciation is computed based on
a 3-year life.

  PROPERTY AND EQUIPMENT

     Property and equipment is stated at cost. Additions, improvements, and
major renewals are capitalized. Maintenance, repairs, and minor renewals are
expensed as incurred. Depreciation is provided using the straight-line method
over 40 years for buildings and improvements, and three to ten years for
machinery and equipment. Amortization of leasehold improvements and leased
equipment covered under capitalized leases is provided using the straight-line
method over the lease term or the useful life of the assets, whichever is
shorter.

  IMPAIRMENT OF LONG-LIVED ASSETS

     In accordance with Statement of Financial Accounting Standard ("SFAS") No.
121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of, ENI continually evaluates whether events and
circumstances have occurred that indicate the remaining estimated useful life of
long-lived assets requires revision or that all or a portion of the remaining
balance may not be recoverable.

                                      ENI
             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

  INCOME TAXES

     Substantially all of ENI's operations are included in Emerson's U.S.
federal, state or foreign income tax returns filed by Emerson legal entities.
However, for purposes of preparing the financial statements of ENI, the tax
provision has been determined as if ENI filed separate tax returns in each tax
jurisdiction in which it operates (see note 8).

     Income taxes are accounted for under the asset and liability method.
Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases and operating loss carryforwards. Deferred tax assets and liabilities are
measured using enacted tax rates expected to apply to taxable income in years in
which those temporary differences are expected to be recovered or settled. The
effect on deferred tax assets and liabilities of a change in tax rates is
recognized in income in the period that includes the enactment date.

  ADVERTISING COSTS

     ENI expenses advertising costs as incurred. Advertising expenses were $386,
$305 and $345 for the years ended September 30, 2000, 1999 and 1998,
respectively. Advertising expenses were $240 (unaudited) and $324 (unaudited)
for the nine month periods ending June 30, 2001 and 2000, respectively.

  SEGMENT REPORTING

     SFAS No. 131, Disclosure about Segments of an Enterprise and Related
Information, requires a business enterprise to report financial and descriptive
information about its reportable operating segments. Operating segments are
components of an enterprise about which separate financial information is
available that is evaluated regularly by the chief operating decision-maker in
deciding how to allocate resources and in assessing performance. ENI operates in
principally one segment, power conversion and control systems and believes its
business units have similar economic characteristics and meet the "aggregation
criteria" of SFAS 131.

  UNAUDITED INTERIM INFORMATION

     The accompanying financial information as of June 30, 2001 and for the nine
months ended June 30, 2001 and 2000 is unaudited. In the opinion of management,
this information has been prepared on substantially the same basis as the annual
combined financial statements and contains all adjustments necessary to present
fairly the financial position and results of operations as of such date and for
such periods. In addition, operating results for the nine-months ended June 30,
2001 are not necessarily indicative of the results that may be expected for the
year ended September 30, 2001.

  RECENT ACCOUNTING PRONOUNCEMENTS

     In July 2001, the FASB issued SFAS No. 141, Business Combinations and SFAS
No. 142, Goodwill and Other Intangible Assets. SFAS No. 141 requires the
purchase method of accounting, eliminates the pooling-of-interests method, and
eliminates the amortization of goodwill for business combinations initiated
after June 30, 2001. SFAS No. 142, which ENI has the option to adopt as of
October 1, 2001 or 2002, requires, among other things, the discontinuance of
goodwill amortization for business combinations initiated before July 1, 2001.
SFAS No. 142 also requires ENI to complete a transitional goodwill impairment
test within six months from the date of adoption. ENI is currently assessing but
has not yet determined the impact of SFAS No. 142 on its financial statements.

                                       F-11

                                      ENI
             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

     In July 2001, the FASB issued SFAS No. 143, Accounting for Asset Retirement
Obligations. SFAS No. 143 (effective for financial statements issued for fiscal
year beginning after June 15, 2002) requires that the fair value of a liability
for an asset retirement obligation be recognized in the period in which it is
incurred if a reasonable estimate of fair value can be made. ENI does not
believe that the adoption of SFAS No. 143 will have any impact on its financial
reporting.

     In August 2001, the FASB issued SFAS No. 144, Accounting for the Impairment
or Disposal of Long-Lived Assets. SFAS No. 144 establishes a single accounting
model, based on the framework established in SFAS No. 121, for long-lived assets
to be disposed of by sale. This statement also resolves significant

     At June 30, 2001 and 2000, September 30, 2000 and 1999, no valuation
allowance has been recorded. Based upon the level of historical taxable income
and projections for future taxable income, management believes it is more likely
than not that the benefits of the deferred tax assets will be realized.

(9) EMPLOYEE BENEFITS

     ENI has a 401(k) Plan sponsored by Emerson which covers all permanent
employees who have completed 30 days of continuous service. Prior to July 1,
1998, participation in the plan was open to all employees of ENI, subject to the
service requirements noted above, except that hourly employees were excluded
from participation. Under the Plan, participants may defer up to 15% of their
gross pay up to a maximum limit as determined by law. Participants are
immediately vested in their contributions. Upon the completion of one year of
service, ENI provides a matching contribution for participants in the Plan equal
to 50% of the contributions by an employee subject to a maximum matching
contribution of 50% of the employee's contribution, not to exceed 2 1/2% of
gross pay. ENI's total contributions to the plan were approximately $231, $226
and $205 for the years ended September 30, 2000, 1999 and 1998, respectively.
Vesting in ENI's matching contribution is based on years of service, with a
participant becoming fully vested after five years of service.

     ENI also maintains a defined-contribution Profit Sharing plan for U.S.
employees. Employees become eligible to participate in the plan on January 1
following attainment of age 21 and the completion of one year of service. The
plan is non-contributory by the employee. The Company's contributions are
discretionary. Participant vesting in the Plan is based on years of service,
with a participant becoming fully vested after five years of service. The
expenses of the plan are also paid by ENI. ENI's total contributions to the plan
were approximately $625, $555 and $265 for the years ended September 30, 2000,
1999 and 1998, respectively.

  DEFINED BENEFIT PLANS

     ENI-Japan maintains a retirement plan for its President whereby upon
retirement the President receives a lump-sum benefit (subject to Emerson
approval). The retirement benefit is calculated by multiplying his monthly
salary upon termination by his years of service and by a coefficient determined
by the Board of Directors. Per the Plan document, the benefit is to be paid six
months after the vote or approval of the shareholders. At September 30, 2000 and
1999 ENI estimated that shareholder approval is more likely than not and accrued
an estimated benefit obligation based upon the provisions above in the amount of
$305 in 2000 and $285 in 1999, respectively.

     ENI also maintains a noncontributory, defined benefit pension plan covering
substantially all employees of its Japanese division which approximates 30
people. Benefits are based on salary and years of

                                       F-16

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

service. The benefit obligation is approximately $376 and $348 at September 30,
2000 and 1999, respectively. The plan is funded through plan assets held in
trust with a fair value of $344 and $305 at September 30, 2000 and 1999,
respectively. The net periodic pension costs approximated $69, $92 and $65 for
2000, 1999 and 1998, respectively. ENI has not funded the unfunded balances at
September 30, 2000 and 1999.

(10) LONG-TERM DEBT

     In 1984, ENI entered into a long-term debt agreement with the County of
Monroe Industrial Development Agency (COMIDA) for a manufacturing facility
located in Rochester, New York. The terms mirror that of the underlying
Industrial Development Revenue Bond which calls for payments of interest only
through July 1, 2014, at which time the Bond is repayable in a lump sum of
$5,000. Interest is reset annually based on bond remarketing, with an option by
ENI to elect a fixed rate, all subject to a maximum rate of 13% per annum. At
September 30, 2000 the interest rate was 4.60%. The bond is effectively secured
by the building, since title does not legally transfer to ENI until payment of
the $5,000.

(11) LEASES

     ENI leases certain equipment as well as office and factory space under
operating leases which expire at various dates through September 2004. Total
expense under the operating leases amounted to $661, $500 and $451 for the years
ended September 30, 2000, 1999 and 1998, respectively. Future minimum lease
payments required under these lease agreements for each of the next five years
and thereafter are as follows:



                                                               OPERATING

                                                                $4,765
                                                                ======


(12) LITIGATION

     The Company is involved in litigation arising in the normal course of
business. In the opinion of management, an adverse outcome to any of this
litigation would not have a material effect on the financial condition of the
Company.

     In March 2001, ENI agreed to settle a patent infringement lawsuit for
$1,500. This settlement has been accrued at September 30, 2000, with the expense
classified as operating expense. Associated legal costs of $2,489, $775 and $125
are also included in operating expenses for 2000, 1999 and 1998, respectively.

(13) RELATED PARTY TRANSACTIONS

     ENI leases production and office space in China and Hong Kong from an
affiliated company. The lease relating to this space has no fixed term with a
monthly payment of approximately $12, $5 and $6 for the years ended September
30, 2000, 1999 and 1998. Approximately $145, $63 and $54 was charged to rent
expense attributable to these leases for the years ended September 30, 2000,
1999 and 1998, respectively.

                                      ENI
             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

     ENI participates in a number of employee benefit plans, including profit
sharing, pension, health care, life insurance and workers compensation, which
are administered by Emerson (see note 9).

     ENI has limited external borrowings and there has been no allocation of
Emerson's consolidated borrowings and related interest expense to ENI. If ENI
were an independent entity, its capital structure may have been significantly
different.

(14) MAJOR CUSTOMERS

     The Division's sales to major customers (purchases in excess of 10% of
total sales) are to entities which are primarily manufacturers of semiconductor
capital equipment and disk storage equipment and, for the nine month period
ending June 30, 2001 and 2000 and the years ended September 30, 2000, 1999 and
1998 are as follows (rounded to the nearest whole percentage):

(15) SUBSEQUENT EVENT (UNAUDITED)

     MKS Instruments, Inc. announced on October 31, 2001 that it has entered
into a definitive agreement to acquire the ENI division of Emerson. Under the
terms of the agreement, MKS will issue 12 million shares of common stock to
Emerson in exchange for the business and assets of ENI. The transaction is
valued at $251 million. MKS will also assume approximately $3.5 million of net
debt. Completion of the acquisition is subject to customary closing conditions,
including the approval of MKS' shareholders. The transaction is expected to be
completed in the first calendar quarter of 2002.

     This Agreement and Plan of Merger is entered into as of October 30, 2001 by
and between MKS Instruments, Inc., a Massachusetts corporation (the "Buyer") and

subject to the terms and conditions of this Agreement, Emerson shall complete

     4.  Buyer desires to cause the Asset Buyers to purchase from the Asset
Sellers, and the Asset Sellers desire to sell to the Asset Buyers, all of the
assets of the Asset Sellers relating to the ENI Business (other than those
assets which are only tangential to the ENI Business and other assets excluded
pursuant hereto), subject to the assumption of related liabilities upon the
terms and subject to the conditions set forth herein.

     5.  Buyer desires to purchase or cause a Subsidiary of Buyer to purchase
from Emerson, and Emerson desires to sell to Buyer or a Subsidiary of the Buyer,
all of the outstanding shares of capital stock of ENI Hong Kong, upon the terms

     6.  Concurrently with the execution and delivery of this Agreement and as a
condition and inducement to Emerson's willingness to enter into this Agreement,
the Specified Buyer Stockholders have entered into a Voting Agreement, dated as
of the date of this Agreement.

deeds and instruments of conveyance and assumption as may be required under
applicable law (or otherwise desirable in order to fully consummate the
transactions contemplated hereby, including without limitation the purchase and
sale of the Acquired Assets and the assumption of the Assumed Liabilities), the
Parties have entered into this Agreement as the master and primary agreement
governing the terms and conditions of the transactions contemplated hereby.

     In consideration of the representations, warranties and covenants herein
contained, the Parties agree as follows:

                                   ARTICLE I

     1.1  Merger; Purchase and Sale of Hong Kong Shares; Purchase and Sale of
Assets and Assumption of Liabilities.

     (a) The Merger.  Upon and subject to the terms and conditions of this
Agreement, at the Closing, the Transitory Subsidiary shall merge with and into
ENI US. From and after the Effective Time, the separate corporate existence of
the Transitory Subsidiary shall cease and ENI US shall continue as the surviving
corporation in the Merger. The Merger shall have the effects set forth in
Section 259 of the Delaware General Corporation Law.

     (b) Purchase and Sale of Hong Kong Shares.  Upon and subject to the terms
and conditions of this Agreement, at the Closing, Emerson shall sell, transfer,
convey, assign and deliver to the Buyer or a Subsidiary of the Buyer, and the
Buyer or a Subsidiary of the Buyer, shall purchase, acquire and accept from

                                       A-6


     (c) Purchase and Sale of Assets and Assumption of Liabilities.

          (i) Transfer of Assets.  Upon and subject to the terms and conditions
     of this Agreement, at the Closing, Emerson shall cause each Asset Seller to
     sell, convey, assign, transfer and deliver to the applicable Asset Buyer,
     and the applicable Asset Buyer shall purchase and acquire the Acquired
     Assets from the applicable Asset Seller.

          (ii) Assumed Liabilities.  Upon and subject to the terms and
     conditions of this Agreement, at the Closing, each of the Asset Buyers,
     respectively, shall assume and agree to pay, perform and discharge when due
     all of the Assumed Liabilities of each Asset Seller.

          (iii) Excluded Liabilities.  It is expressly understood and agreed
     that, notwithstanding anything to the contrary in this Agreement, the

     1.2  Further Assurances.

     (a) At any time and from time to time after the Closing, at the Buyer's
request and without further consideration, Emerson shall promptly execute and
deliver (or shall cause its appropriate Subsidiary to execute and deliver) such
instruments of sale, transfer, conveyance, assignment and confirmation as the
Buyer may reasonably request, and take all such other action as the Buyer may
reasonably request, more effectively to transfer, convey and assign to the Buyer
or a Subsidiary of the Buyer, and to confirm the Buyer's or a Subsidiary of the
Buyer's title to, all of the Hong Kong Shares outstanding on the Closing Date,
and all of the Acquired Assets and to put the Buyer in actual possession and
operating control (through its ownership of the Company Shares and the Acquired
Assets) of the assets, properties and business of the ENI Business (other than
the Excluded Assets), the Companies and the Company Subsidiaries.

     (b) Anything in this Agreement to the contrary notwithstanding, this
Agreement shall not constitute an agreement to assign any Deferred Item in
relation to which a Deferred Consent has not been obtained. If a Deferred
Consent is not obtained (a) the Deferred Item shall be withheld from the
Reorganization or the sale pursuant to this Agreement, as the case may be, (b)
from and after the Closing, Emerson and Buyer will cooperate, in all reasonable
respects, to obtain such Deferred Consent as soon as practicable after the
Closing (after receipt of which such assignment or transfer shall promptly be
completed), and (c) until such Deferred Consent is obtained, Emerson and Buyer
will cooperate, in all reasonable respects, to provide to Buyer the benefits
under the Deferred Item to which such Deferred Consent relates (with Buyer
entitled to all the gains and responsible for all the losses, taxes, liabilities
and/or obligations thereunder). In particular, in the event that any such
Deferred Consent is not obtained prior to the Closing, then Buyer and Emerson
shall enter into such arrangements (including subleasing or subcontracting if
permitted) to provide to the Parties the economic and operational equivalent of
obtaining such Deferred Consent and assigning or transferring such Deferred
Item, including enforcement for the benefit of Buyer of all claims or rights
arising thereunder, and the performance by Buyer of the obligations thereunder
on a prompt and punctual basis.

          (a) Not later than 50 calendar days after the Closing Date, Emerson
     shall deliver to the Buyer a Statement of Closing Working Capital,
     including a schedule of all of the line items thereof, which shall be
     prepared in accordance with GAAP applied consistently with past practice
     (to the extent such past practices are consistent with GAAP). The cost of
     the preparation of the Statement of Closing Working Capital shall be paid
     by Emerson. The Buyer shall afford Emerson and Emerson's Auditor reasonable
     access to the books and records of each Company, each of the Company
     Subsidiaries and each Asset Buyer during normal business hours for purposes
     of the preparation of the Statement of Closing Working Capital.

          (b) The Statement of Closing Working Capital delivered pursuant to
     paragraph (a) above shall be accompanied by relevant backup materials,
     schedules and a statement setting forth the amount, if any, by which the
     Closing Working Capital is greater than, or less than, the Target Amount.

          (c) In the event that the Buyer disputes the Statement of Closing
     Working Capital or the calculation of the Closing Working Capital, the
     Buyer shall deliver a Dispute Notice to Emerson stating the amount, nature
     and basis of such dispute, within 30 calendar days after delivery of the
     Statement of Closing Working Capital. In the event of such a dispute, the
     Buyer and Emerson shall first use their diligent good faith efforts to
     resolve such dispute between themselves. If the parties are unable to
     resolve the dispute within 30 calendar days after delivery of the Dispute
     Notice, then any remaining items in dispute shall be submitted to an
     Arbitrator selected in writing by Emerson and the Buyer or, if Emerson and
     the Buyer fail or refuse to select a firm within 10 calendar days after
     written request therefor by Emerson or the Buyer, such Arbitrator shall be
     selected in accordance with the rules of the Boston, Massachusetts office
     of the American Arbitration Association. All determinations pursuant to
     this paragraph (c) shall be in writing and shall be delivered to the
     Parties. The determination of the Arbitrator as to the resolution of any
     dispute shall be binding and conclusive upon all Parties. A judgment on the
     determination made by the Arbitrator pursuant to this Section 1.6 may be
     entered in and enforced by any court having jurisdiction thereover. Nothing
     herein shall be construed to authorize or permit the Arbitrator to:

             (i) determine any questions or matters whatsoever under or in
        connection with this Agreement except for the resolution of differences
        between the Parties regarding the determination of the Closing Working
        Capital;

                                       A-9


             (ii) resolve any such differences by making any adjustment to the
        Statement of Closing Working Capital that is outside of the range
        defined by amounts as finally proposed by the Parties.

          (d) The fees and expenses of the Arbitrator in connection with the
     resolution of disputes pursuant to paragraph (c) above shall be shared
     equally by Emerson and the Buyer; provided that if the Arbitrator
     determines that one Party has adopted a position or positions with respect
     to the Statement of Closing Working Capital or the calculation of the
     Closing Working Capital that is frivolous or clearly without merit, the
     Arbitrator may, in its discretion, assign a greater portion of any such
     fees and expenses to such Party.

          (e) Failure of Buyer to deliver a Dispute Notice within 30 days after
     receiving the Statement of Closing Working Capital, or notification by the
     Buyer to Emerson that no Dispute Notice will be given, shall constitute
     acceptance of the Closing Working Capital as set forth on the Closing
     Working Capital Statement and there shall be no additional payment required
     or adjustment to the Purchase Price pursuant to this Section. Buyer shall
     be deemed to accept all portions of the Statement of Closing Working
     Capital that are not set forth in such Dispute Notice.

          (f) Immediately upon the resolution of all disputes, if any, pursuant
     to this Section 1.6, the Purchase Price shall be adjusted as follows:

             (i) If the Closing Working Capital is less than the Target Amount,
        then within five (5) business days of the final determination of the
        Closing Working Capital, Emerson shall pay to Buyer, in cash, the amount
        of such deficiency, and such payment shall be considered to be a
        reduction in the Purchase Price allocable to the Merger Consideration.

             (ii) If the Closing Working Capital is equal to or greater than the
        Target Amount, there shall be no additional payment required or
        adjustment to the Purchase Price pursuant to this Section.

          (g) If there is a reduction in Closing Working Capital caused by an
     event or circumstance which would give rise to an indemnification claim
     under Article VII of this Agreement, and as a result of such reduction in
     Closing Working Capital, the Purchase Price is reduced pursuant to Section
     1.6(f)(i), the Buyer and its Subsidiaries shall not be entitled to
     indemnification for such claim except to the extent it exceeds the amount
     of the reduction of the Purchase Price.

Company, no Company Subsidiary and, to the knowledge of Emerson, no other party,
is in breach or violation of, or default under, any such agreement, and no event
has occurred, is pending or, to the knowledge of Emerson, has been or is
threatened, which, after the giving of notice, with lapse of time, or otherwise,
would constitute a breach or default by any Asset Seller, any Company or any
Company Subsidiary or, to the knowledge of Emerson, any other party under such
agreement, except as would not reasonably be expected to have a Company Material
Adverse Effect.

     (c) Each agreement entered into by ENI US under the so-called KanBan
Documents of Understanding is terminable by ENI US upon not more than 90 days
written notice by ENI US to the other party without the payment of any
termination or cancellation fee other than payment for finished goods and work
in process at the time of such termination or cancellation.

reflected on the Statement of Closing Working Capital are valid receivables
subject to no setoffs or counterclaims and are current and collectible, net of
the applicable reserve for bad debts shown on the Statement of Closing Working
Capital. A complete and accurate list of the 20 largest accounts receivable
reflected on the Most Recent Balance Sheet, showing the aging thereof, is
included in Section 2.17 of the Disclosure Schedule.

and automobile insurance policies and bond and surety arrangements) relating to
the ENI Business to which any Existing ENI Subsidiary, any Company or any

There is no material claim pending under any such policy with respect to the ENI
Business as to which coverage has been questioned, denied or disputed by the
underwriter of such policy except any claims, individually or in the aggregate,

All premiums due and payable under all such policies have been paid, no Asset
Seller, no Company and no Company Subsidiary may be liable for retroactive
premiums or similar payments, and the Existing ENI Subsidiaries, the Companies
and the Company Subsidiaries are otherwise in compliance in all material
respects with the terms of such policies. Emerson has no knowledge of any
threatened termination of, or premium increase with respect to, any such policy.

     2.20  Litigation.  There is no Legal Proceeding which is pending, and no
Existing ENI Subsidiary, no Asset Seller, no Company and no Company Subsidiary,
has received written notice of any threatened Legal Proceeding with respect to
the ENI Business which (a) seeks either damages in excess of $25,000 or

alter or delay the transactions contemplated by this Agreement. There are no
judgments, orders or decrees outstanding with respect to the ENI Business
against any Existing ENI Subsidiary.

     2.21  Warranties.  With respect to the contracts with the five largest
customers of the ENI Business as of the date of this Agreement, there are no
guaranties, warranties, rights of return, rights of credit or other indemnity

compensation of each such person. Each employee of the ENI Business has entered
into a confidentiality/assignment of inventions agreement with Emerson or an
Existing ENI Subsidiary, a copy or form of which has previously been delivered
to the Buyer. Each such confidentiality agreement and each such assignment of
inventions agreement with employees of ENI US will continue to be legal, valid,
binding and enforceable and in full force and effect for the benefit of the
Buyer, a Company or an appropriate Company Subsidiary immediately following the
Closing in accordance with the terms thereof as in effect immediately prior to
the Closing. Section 2.22 of the Disclosure Schedule contains a list of all
employees of the ENI Business who are a party to a non-competition agreement
with Emerson, any Asset Seller or any Existing ENI Subsidiary; copies of the
forms of which agreements have previously been delivered to the Buyer. The
transactions contemplated by this Agreement will not have any effect on the
enforceability of any such non-competition agreements. As of the date of this
Agreement, to the knowledge of Emerson, no engineer employed by the ENI
Business, no member of the sales or marketing personnel employed by the ENI
Business, no employee of the ENI Business whose annual rate of compensation
exceeds $75,000 and

                                       A-20


no group of employees performing services related to the ENI Business has any
plans to terminate employment with Emerson or any Existing ENI Subsidiary.

     (b) The ENI Business is not a party to or bound by any collective
bargaining agreement. None of the Existing ENI Subsidiaries has experienced any
strikes, grievances, claims of unfair labor practices or other collective
bargaining disputes related to the ENI Business. Emerson has no knowledge of any
organizational effort made or threatened, either currently or within the past
two years, by or on behalf of any labor union with respect to employees of
Emerson, any Asset Seller or any Existing ENI Subsidiary performing services
related to the ENI Business.

     2.23  Employee Benefits.

     (a) Section 2.23(a) of the Disclosure Schedule contains a complete and
accurate list of all Company Plans. Such section of the Disclosure Schedule
identifies any such Company Plan which is unwritten and contains a description
of the nature of such Company Plan.

     (b) With respect to the Company Plans, complete and accurate copies have
been delivered to the Buyer of (i) all written Company Plans, (ii) all related
trust agreements, group annuity contracts, administration and similar
agreements, insurance contracts, investment management and investment advisory
agreements, (iii) current summary plan descriptions, employee handbooks, or
other similar employee communications, (iv) all personnel, payroll and
employment manuals and policies, (v) the most recent annual report filed with
the Internal Revenue Service for each Company Plan (Forms 5500, 5500C or 5500R)
with schedules attached, and (vi) where applicable, the most recent plan
financial statements for each Company Plan.

     (c) Each Company Plan has been administered in accordance with its terms,
and Emerson, each Asset Seller, each Existing ENI Subsidiary, each ERISA
Affiliate, each Company and each Company Subsidiary has met its obligations with
respect to each Company Plan and has timely made all required contributions
thereto, and each Asset Seller, each Existing ENI Subsidiary, each Company, each
Company Subsidiary, each ERISA Affiliate and each Company Plan is in compliance
with the currently applicable provisions of ERISA and the Code and the
regulations thereunder (including Section 4980 B of the Code, Subtitle K,
Chapter 100 of the Code and Sections 601 through 608 and Section 701 et seq. of
ERISA), except for any such failure which would not reasonably be expected to
have a Company Material Adverse Effect. All filings and reports as to each
Company Plan required to have been submitted to the Internal Revenue Service or
to the United States Department of Labor have been accurately completed and
timely submitted. With respect to the Company Plans, no event has occurred and,
to the knowledge of Emerson, there exists no condition or set of circumstances
in connection with which the Buyer, any Company, any Company Subsidiary or any
plan participant could be subject to any liability (including penalties or
Taxes) under ERISA (including Title IV thereof), the Code or any other
applicable law, nor will the transactions contemplated by the Reorganization or
by this Agreement give rise to any such liability. No Existing ENI Subsidiary,
no Company and no Company Subsidiary has incurred any liability or will be
deemed to have assumed any liability which will survive the Closing, under ERISA
or the Code or other applicable law with respect to Employee Benefits Plans, as
a result of such Company or such Company Subsidiary's inclusion in the same
controlled group (as defined in Code Section 414(b), (c), (m) or (o)) as Emerson
or any ERISA Affiliate of Emerson.

     (d) With respect to the Company Plans, there are no benefit obligations for
which contributions have not been made or properly accrued and there are no
benefit obligations which have not been accounted for by reserves, or otherwise
properly footnoted in accordance with GAAP, on the Financial Statements, except
for any failure to contribute, accrue or account which would not reasonably be
expected to have a Company Material Adverse Effect. No Asset Seller, no Company
and no Company Subsidiary has any liability (contingent or otherwise) for
benefits under any Company Plan, except as set forth in the Financial
Statements. The assets of each Company Plan which is funded are reported at
their fair market value on the books and records of such Company Plan. No Stand
Alone Plan has assets that include securities issued by Emerson, any Asset
Seller, any Existing ENI Subsidiary, any Company, any Company Subsidiary or any
of their ERISA Affiliates.
                                       A-21


     (e) All the Company Plans that are intended to be qualified under Section
401(a) of the Code have received determination letters from the Internal Revenue
Service to the effect that such Company Plans are qualified and the plans and
trusts related thereto are exempt from U. S. federal income Taxes under Sections
401(a) and 501(a), respectively, of the Code, no such determination letter has
been revoked and revocation has not been threatened, no fact or circumstances
exists giving rise to a likelihood that such determination letter would be
revoked, and no act or omission has occurred that would materially increase its
cost. Each Company Plan which is required to satisfy Section 401(k)(3) or
Section 401(m)(2) of the Code has been tested for compliance with, and satisfies
the requirements of Section 401(k)(3) and Section 401(m)(2) of the Code, as the
case may be, for each plan year ending prior to the Closing Date, except for any
increase that would not reasonably be expected to have a Company Material
Adverse Effect.

     (f) None of any Asset Seller, any Company, any Existing ENI Subsidiary or
any Company Subsidiary has (i) ever maintained an Employee Benefit Plan which
was ever subject to Section 412 of the Code or Title IV of ERISA, (ii) ever been
obligated to contribute to a "multiemployer plan" (as defined in Section
4001(a)(3) of ERISA), or (iii) has ever contributed to a multiemployer plan with
respect to which there has been any withdrawal liability which has not been
fully satisfied and no such multiemployer plan is insolvent or in
reorganization. No Company Plan is funded by, associated with or related to a
"voluntary employee's beneficiary association" within the meaning of Section
501(c)(9) of the Code. No Existing ENI Subsidiary, no Company and no Company
Subsidiary has incurred any liability or will be deemed to have assumed any
liability which will survive the Closing under ERISA, the Code or other
applicable law with respect to Employee Benefits Plans, as a result of such
Company's or such Company Subsidiary's inclusion in the same controlled group
(as defined in Code Section 414(b), (c), (m) or (o)) as Emerson or any ERISA
Affiliate of Emerson.

     (g) Each Stand Alone Plan is amendable and terminable unilaterally by the
Asset Seller, the Company or the Company Subsidiary party thereto or covered
thereby at any time without liability to any Asset Seller, any Company or any
Company Subsidiary as a result thereof, and no Stand Alone Plan, plan
documentation or agreement, summary plan description or other written
communication distributed generally to employees by its terms prohibits any
Asset Seller, any Company or any Company Subsidiary party thereto or covered
thereby from amending or terminating any such Stand Alone Plan, or in any way
limits such action.

     (h) Section 2.23(h) of the Disclosure Schedule discloses each (i) agreement
with any executive officer or other key employee of the ENI Business (A) the
benefits of which are contingent, or the terms of which are altered, upon the
occurrence of a transaction involving the ENI Business of the nature of any of
the transactions contemplated by the Reorganization or by this Agreement, except
for any alteration which would not reasonably be expected to have a Company
Material Adverse Effect, (B) providing any term of employment or compensation
guarantee or (C) providing severance benefits or other benefits after the
termination of employment of such executive officer or key employee or (ii)
agreement or plan binding any Existing ENI Subsidiary or, after the Closing, the
Buyer, any Buyer Subsidiary, any Company or any Company Subsidiary, including
any stock option plan, stock appreciation right plan, restricted stock plan,
stock purchase plan or severance benefit plan, any of the benefits of which
shall be increased, or the vesting of the benefits of which shall be accelerated
or the benefits of which will become payable (or permit an employee to
voluntarily terminate and receive benefits which will be payable) by, the
occurrence of any of the transactions contemplated by the Reorganization or by
this Agreement or the value of any of the benefits of which shall be calculated
on the basis of any of the transactions contemplated by the Reorganization or by
this Agreement.

     (i) No Company, no Company Subsidiary and no Existing ENI Subsidiary has
within the past six years paid any amount that could reasonably be expected to
be treated as an "excess parachute payment" as defined in Section 280G of the
Code. None of the transactions contemplated by the Reorganization or by this
Agreement will give rise to any loss of deductibility under Code Section 280G or
excise tax under Code Section 4999.

                                       A-22


     (j) Other than as required under Section 601 et seq. of ERISA, none of the
Company Plans promises or provides health or other welfare benefits or coverage
to any person following retirement or other termination of employment with the
ENI Business. Section 2.23(j) of the Disclosure Schedule lists each Company Plan
which provides benefits after termination of employment with the ENI Business
(other than medical benefits required to be continued under Section 4980B of the
Code and part 6 of Subtitle B of Title I of ERISA) and the amount by which the
present value of benefits accrued under each such Company Plan exceeds the fair
market value of the assets of each such Company Plan.

     (k) There is no action, suit, proceeding, claim, arbitration, audit or
investigation pending or, to the knowledge of Emerson, threatened, with respect
to any Company Plan, other than claims for benefits in the ordinary course, that
would reasonably be expected to result in liability to any Existing ENI
Subsidiary, any Asset Seller, any Company, any Company Subsidiary, or any
Company Plan, except for any liability which would not reasonably be expected to
have a Company Material Adverse Effect. No Stand Alone Plan is the subject of or
has received notice that it is the subject of examination by a Governmental
Entity or has been a participant in a government sponsored amnesty, voluntary
compliance or similar program.

     (l) Each Company Plan maintained outside the United States is in
compliance, and the books and records thereof are maintained in compliance, with
all applicable laws, rules and regulations of the jurisdiction in which such
Company Plan is maintained. Section 2.23(l) of the Disclosure Schedule lists
each country in which any of the Existing ENI Subsidiaries has operations and
the number of employees in each such country.

     (m) Each individual who has received compensation for the performance of
services on behalf of the ENI Business has been properly classified as an
employee or independent contractor in accordance with applicable law.

     (n) Section 2.23(n) of the Disclosure Schedule sets forth the amount
accrued with respect to the vacation, accrued sick time and/or earned time off
of ENI Employees as of September 30, 2001, whether or not formally accrued for
financial statement purposes.

     2.24  Environmental Matters.

     (a) The ENI Business has been conducted and is being conducted in all
material respects in compliance with all applicable Environmental Laws. There is
no pending or, to the knowledge of Emerson, threatened civil or criminal
litigation, written notice of violation, formal administrative proceeding, or to
the knowledge of Emerson, any governmental investigation, inquiry or information
request, in each case relating to any Environmental Law and relating to the ENI
Business. Without limiting any of the foregoing, there is no pending litigation,
or to the knowledge of Emerson, any threatened claim or litigation with respect
to the ENI Business relating to: (i) exposure to or presence of Materials of
Environmental Concern; (ii) noises, odors or vibrations at or from any real
property or facility currently or formerly owned, leased, occupied or controlled
by the ENI Business; or (iii) indoor air quality in each case, which would
reasonably be expected to result in a Company Material Adverse Effect.

     (b) No Asset Seller, no Company and no Company Subsidiary has any
liabilities or obligations, whether known or unknown, arising from the release
of any Materials of Environmental Concern into the environment that occurred or
existed at or prior to the Closing Date. No Existing ENI Subsidiary has received
or been informed in writing of any fact, condition or correspondence with
respect to the ENI Business which indicates that any Existing ENI Subsidiary may
be responsible for a release of any Materials of Environmental Concern to the
environment. No Existing ENI Subsidiary has been named or identified in writing
under any Environmental Law with respect to the ENI Business as a party
potentially responsible for a release to the environment of any Materials of
Environmental Concern. To the knowledge of Emerson, other than in compliance
with Environmental Laws, there have been no releases or threatened releases of
any Materials of Environmental Concern into the environment at any parcel of
real property or any facility formerly or currently owned, leased, operated or
controlled by any Existing ENI Subsidiary with respect to the ENI Business that
could reasonably be expected to have a Company Material Adverse

                                       A-23


Effect. To the knowledge of Emerson, there have been no releases or threats of
releases of Materials of Environmental Concern with respect to the ENI Business
at parcels or facilities other than those owned, leased, operated or controlled
by any Existing ENI Subsidiary that reasonably could be expected to have a
material adverse effect on the real property or facilities owned, leased,
operated or controlled by the ENI Business.

     (c) No Asset Seller, no Company and no Company Subsidiary is a party to or
bound by any court order, administrative order, consent order or other agreement
with any Governmental Entity entered into in connection with any legal
obligation or liability arising under any Environmental Law with respect to the
ENI Business.

     (d) Set forth in Section 2.24(d) of the Disclosure Schedule is a list of
all environmental audits, reports, studies and investigations of which Emerson
has knowledge relating to the environmental status of any real property and/or
premises currently or previously owned or operated by Emerson, any Asset Seller
or any Existing ENI Subsidiary with respect to the ENI Business (whether
conducted by or on behalf of Emerson, any Asset Seller, any Existing ENI
Subsidiary or a third party, and whether done at the initiative of Emerson, any
Asset Seller, any Existing ENI Subsidiary or directed by a Governmental Entity
or other third party) which were issued or conducted during the past five years
and which Emerson has possession of or access to as of the date hereof. A
complete and accurate copy of each such document has been provided to the Buyer.

     (e) None of Emerson, any Asset Seller or any Existing ENI Subsidiary has
received notice that it may have any material environmental liability for any
solid or hazardous waste transporter or treatment, storage or disposal facility
that has been used by any Existing ENI Subsidiary in connection with the ENI
Business.

     (f) Except as set forth in this Section 2.24, Section 2.12(a) and
Section 2.27, Emerson is not making any representations or warranties relating
to any environmental matters.

     2.25  Legal Compliance.  The ENI Business is currently being conducted, and
has at all times been conducted, in compliance with each applicable law
(including rules and regulations thereunder) of any federal, state, local or
foreign government, or any Governmental Entity, except for any violations or
defaults that, individually or in the aggregate, have not had and would not
reasonably be expected to have a Company Material Adverse Effect. None of
Emerson, any Asset Seller, any Existing ENI Subsidiary, any Company or any
Company Subsidiary, has received any notice or communication from any
Governmental Entity alleging noncompliance with any applicable law, rule or
regulation as it relates to the ENI Business.

     2.26  Customers and Suppliers.  Section 2.26 of the Disclosure Schedule
sets forth a list of (a) the top 15 customers of the ENI Business based on
revenues generated from product sales during the last full fiscal year and the
amount of revenues accounted for by such customer from product sales during each
such period and (b) each supplier that is the sole source of any significant
product or service to the ENI Business. No such customer or supplier has
indicated within the past year that it intends to cease doing business with the
ENI Business. To Emerson's knowledge, no unfilled customer order or commitment
obligating the ENI Business to process, manufacture or deliver products or
perform services will result in a loss at the gross margin, on a consolidated
basis, to the ENI Business upon completion of performance.

     2.27  Permits.  Section 2.27 of the Disclosure Schedule sets forth a list
of all material Permits (including those issued or required under Environmental
Laws and those relating to the occupancy or use of owned or leased real
property) issued to or held by any Existing ENI Subsidiary with respect to the
ENI Business. Such listed Permits are the only material Permits that are
required to conduct the ENI Business as presently conducted. Each such material
Permit is in full force and effect; the applicable Existing ENI Subsidiary is in
compliance with the terms of each such Permit; and, to the knowledge of Emerson,
no suspension or cancellation of any material Permit is threatened and there is
no basis for believing that each such Permit will not be renewable without any
material changes upon expiration, except for any noncompliance, cessation of
effectiveness, suspension or cancellation which, individually or

                                       A-24


in the aggregate, would not reasonably be expected to result in a Company
Material Adverse Effect. Each such Permit will continue in full force and effect
immediately following the Closing. A complete and accurate copy of each material
Permit has been provided to the Buyer.

     2.28  Certain Business Relationships With Affiliates.  Section 2.28 of the
Disclosure Schedule describes any non-arms length transactions or agreements
with respect to the ENI Business between Emerson, any Asset Seller, any Existing
ENI Subsidiary, any Company or any Company Subsidiary and any Affiliate thereof
which occurred or have existed since the beginning of the time period covered by
the Financial Statements.

     2.29  Restrictions on Business Activities.  After giving effect to the
Reorganization, there will be no agreement, commitment, judgment, injunction,
order or decree to which an Asset Seller, a Company or any Company Subsidiary is
a party or which will otherwise be binding upon the Buyer, a Subsidiary of the
Buyer, any Company, any Company Subsidiary or the ENI Business which will or
reasonably could be expected to result in the licensing of, or any grant of
rights to, any Intellectual Property of the Buyer to any third party.

     2.30  Investment Representations.

     (a) Emerson is acquiring the Closing Shares for Emerson's own account for
investment only, and not with a view to, or for sale in connection with, any
distribution of such Closing Shares in violation of the Securities Act, or any
applicable state law.

     (b) Emerson has had adequate opportunity to obtain from publicly available
sources or from representatives of the Buyer such information, in addition to
the representations set forth in this Agreement, as is necessary to evaluate the
merits and risks of the Emerson's investment in the Buyer.

     (c) Emerson is an "accredited investor" as defined in Rule 501(a) of the
Securities Act and has sufficient experience in business, financial and
investment matters to be able to evaluate the risks involved in the acquisition
of the Closing Shares to be issued to Emerson and to make an informed investment
decision with respect to such investment. Emerson is capable of bearing the
economic risk of Emerson's investment in the Closing Shares indefinitely.

     (d) Emerson agrees and understands that the Closing Shares have not been
registered under the Securities Act and are "restricted securities" within the
meaning of Rule 144 under the Securities Act; and that the Closing Shares cannot
be sold, transferred or otherwise disposed of unless they are subsequently
registered under the Securities Act or an exemption from registration is then
available.

     (e) Emerson agrees and understands that a legend substantially in the
following form will be placed on the certificate representing the Closing
Shares.

     "The shares represented by this certificate have not been registered under
the Securities Act of 1933, as amended, and may not be sold, transferred or
otherwise disposed of in the absence of an effective registration statement
under such Act or an opinion of counsel satisfactory to the corporation to the
effect that such registration is not required."

     2.31  Brokers' Fees.  Except for the fee payable by Emerson to SG Cowen
Securities Corporation, none of Emerson, any Asset Seller, any Existing ENI
Subsidiary, any Company or any Company Subsidiary has any liability or
obligation to pay any fees or commissions to any broker, finder or agent with
respect to the transactions contemplated by this Agreement.

     2.32  Banking Facilities.  Section 2.32 of the Disclosure Schedule
identifies:

          (a) each bank, savings and loan or similar financial institution in
     which the ENI Business has any account and the numbers of the accounts
     maintained by the ENI Business thereat; and

          (b) the names of all persons who are authorized to draw on each such
     account.

                                       A-25


                                  ARTICLE III

sections corresponding to the numbered and lettered sections contained in
Article III of this Agreement. The disclosures in any section of the Buyer
Disclosure Schedule shall qualify other sections in this Article III only to the
extent it is clear from a reading of the disclosure that such disclosure is
applicable to such other sections. For purposes of this Article III, the phrase
"to the knowledge of the Buyer" or any phrase of similar import shall be deemed
to refer to the actual knowledge of each of the officers of the Buyer, as well
as any other knowledge which any of such persons would have possessed had they
made reasonable inquiry with respect to the matter in question.

the failure to be so qualified could reasonably be expected to have a Buyer
Material Adverse Effect. The Buyer has all requisite corporate power and
authority to carry on the businesses in which it is engaged and to own and use
the properties owned and used by it, except the failure to have such corporate
power and authority would not reasonably be expected to have a Buyer Material
Adverse Effect. Buyer is not in default under or in violation of any provision
of its Articles of Organization and by-laws, except for any such default or
violation which would not reasonably be expected to result in a Buyer Material
Adverse Effect.

     3.2  Authorization of the Transaction.  The Buyer has all requisite power
and authority to execute and deliver this Agreement and the Ancillary Agreements
and to perform its obligations hereunder and thereunder. Subject to the Buyer
Requisite Vote, the execution and delivery by the Buyer of this Agreement and
the Ancillary Agreements and the consummation by the Buyer of the transactions
contemplated hereby and thereby have been duly and validly authorized by all
necessary corporate action on the part of the Buyer. This Agreement has been
duly and validly executed and delivered by the Buyer and constitutes and each of
the Ancillary Agreements, upon its execution and delivery, by the Buyer, will
constitute, a valid and binding obligation of the Buyer, enforceable against it
in accordance with its terms.

nonassessable and not subject to or issued in violation of any purchase option,
call option, right of first refusal, preemptive right or any subscription right.
The Buyer does not have outstanding any bonds, debentures, notes or other
obligations the holders of which have the right to vote (or convertible into or
exercisable for securities having the right to vote) with the stockholders of
the Buyer on any matter. There are no outstanding stock appreciation, phantom
stock or similar rights with respect to Buyer. There are no agreements, voting
trusts, proxies or understandings with respect to the voting, or registration

consummation by the Buyer of the transactions contemplated hereby or thereby,
will (a) conflict with or violate any provision of the organizational documents
of the Buyer, (b) require on the part of the Buyer any notice to or filing with,

expense, all waivers, permits, consents, approvals or other authorizations from
Governmental Entities, and to effect all registrations, filings and notices with
or to Governmental Entities, as may be required for such Party to consummate the
transactions contemplated by this Agreement and to otherwise comply with all

instituted by any Governmental Entity challenging any of the transactions
contemplated hereby as violative of any Antitrust Law, each of Buyer and Emerson
shall use reasonable commercial efforts to resolve such objections or challenge
such Governmental Entity under such Antitrust Law so as to permit consummation
of the transactions contemplated by this Agreement. Notwithstanding anything to

order to enjoin consummation of the transactions which are the subject of this
Agreement.

in Section 8.4 thereof, which are required as a result of the transactions
contemplated under this Agreement.

     (d) Emerson may seek to obtain the release of its obligations as guarantor
under the IDRB Lease and the Buyer shall cooperate with Emerson in obtaining
such a release and, if requested by Emerson, the Buyer agrees to act as
guarantor of the obligations under the IDRB Lease by executing and delivering a
guaranty with terms that are similar in all material respects to the terms of
the guaranty executed by Emerson with respect to the IDRB Lease.

     4.3  Proxy Statement.

financial statements and affairs of each Asset Seller, each Company and each
Company Subsidiary, as, in the reasonable judgment of Buyer or its counsel, may
be required or appropriate for inclusion in the Proxy Statement, or in any
amendments or supplements thereto, and to cause its counsel and auditors to
cooperate with Buyer's counsel and auditors in the preparation of the Proxy
Statement. Without limiting the generality of the foregoing, Emerson shall cause
each Asset Seller's, each Company's and each Company Subsidiary's management and
their respective independent auditors to facilitate on a timely basis (i) the
preparation and delivery to Buyer for inclusion in the Proxy Statement of
financial statements (including pro forma financial statements if required) as
required by the Buyer to comply with applicable rules and regulations of the
SEC, (ii) the review of any Asset Seller, Company or Company Subsidiary audit or
review work papers for up to the past three (3) complete fiscal years, including
the examination of selected interim financial statements and data and (iii) the

Company's and any Company Subsidiaries' independent accountants as may be
required by applicable laws or the rules or regulations promulgated thereunder.

     (b) The Buyer shall respond to any comments of the SEC and shall use its
Reasonable Best Efforts to have the Proxy Statement cleared by the SEC under the
Exchange Act as promptly as practicable after such filing. The Buyer shall
notify Emerson promptly upon the receipt of any comments from the SEC or its
staff or any other government officials and of any request by the SEC or its
staff or any other government officials for amendments or supplements to the
Proxy Statement or for additional information and shall supply Emerson with
copies of all correspondence between the Buyer or any of its representatives, on
the one hand, and the SEC, or its staff or any other government officials, on
the other hand, with respect to the Proxy Statement.

     (c) The Buyer shall use its Reasonable Best Efforts to cause the Proxy
Statement to comply in all material respects with all applicable requirements of
law and the rules and regulations promulgated thereunder. Whenever any event
occurs which is required to be set forth in an amendment or supplement to the
Proxy Statement, the Buyer shall promptly inform Emerson of such occurrence and
cooperate in filing such amendment or supplement with the SEC or its staff or
any other government officials.

     4.4  Stockholders Meeting.

     The Buyer, acting through the Buyer's board of directors, shall take all

Buyer Requisite Vote of the Buyer Voting Proposal. Except as set forth in
Section 4.9(b), the Buyer's full board of directors shall (i) recommend approval
of the Buyer Voting Proposal and include such recommendation in the Proxy
Statement and (ii) use Reasonable Best Efforts to solicit and obtain such
approval. Notwithstanding anything to the contrary contained in this Agreement,
after consultation with Emerson, the Buyer may adjourn or postpone the Buyer
Stockholder Meeting to the extent necessary to ensure that any required
supplement or amendment to the Proxy Statement is provided to the Buyer's
stockholders or, if as of the time for which the Buyer Stockholder Meeting is
originally scheduled (as set forth in the Proxy Statement) there are
insufficient shares of Buyer Common Stock represented (either in person or by
proxy) to constitute a quorum necessary to conduct the business of the Buyer
Stockholder Meeting.

Seller, each Company and each Company Subsidiary, to conduct its operations

     contract, arrangement or benefit plan;

          (iv) acquire, sell, lease, license or dispose of any assets or

     4.7  Notice of Breaches.

     (a) From the date of this Agreement until the Closing, Emerson may deliver
to the Buyer supplemental information concerning events or circumstances
occurring subsequent to the date hereof which would render any representation,
warranty or statement in this Agreement or the Disclosure Schedule inaccurate or
incomplete at any time after the date of this Agreement until the Closing. No
such supplemental information shall be deemed to avoid or cure any
misrepresentation or breach of warranty or constitute an amendment of any
representation, warranty or statement in this Agreement or the Disclosure
Schedule; provided that if such supplemental information relates to an event or
circumstance occurring subsequent to the date hereof in the Ordinary Course of
Business (without breach of Section 4.5) and if the Buyer would have the right
to terminate this Agreement pursuant to Section 8.1(b) as a result of the
information so disclosed and it does not exercise such right prior to the

representation, warranty or statement to which it relates for purposes of
Article VII of this Agreement.

     (b) From the date of this Agreement until the Closing, the Buyer may
promptly deliver to Emerson supplemental information concerning events or
circumstances occurring subsequent to the date hereof which would render any
representation or warranty in this Agreement or the Buyer Disclosure Schedule
inaccurate or incomplete at any time after the date of this Agreement until the
Closing. No such supplemental information shall be deemed to avoid or cure any
misrepresentation or breach of warranty or constitute an amendment of any
representation or warranty in this Agreement or the Buyer Disclosure Schedule;
provided that if such supplemental information relates to an event or
circumstance occurring subsequent to the date hereof in the Ordinary Course of
Business and if Emerson would have the right to terminate this Agreement
pursuant to Section 8.1(c) as a result of the information so disclosed and it
does not exercise such right prior to the Closing, then such supplemental
information shall constitute an amendment of the representation or warranty to
which it relates for purposes of Article VII of this Agreement.

     4.8  Buyer's Board of Directors.  Prior to Closing, Buyer shall take all
necessary action to cause the number of members of the Buyer's board of
directors to be fixed at eight and to cause James G. Berges, or upon his

directors effective as of Closing, as a member of the class of directors whose

     4.9  No Solicitation.

     (a) Except as set forth in this Section 4.9, Buyer shall not, nor shall
Buyer authorize or permit any of its Subsidiaries or any of its directors,
officers, employees, investment bankers, attorneys, accountants, consultants or
other agents, advisors or representatives to directly or indirectly:

          (i) solicit, initiate, encourage or take any other action to
     facilitate any inquiries or the making of any proposal or offer that
     constitutes, or could reasonably be expected to lead to, any Acquisition
     Proposal;

          (ii) enter into, continue or otherwise participate in any discussions
     or negotiations regarding, furnish to any person any information relating
     to Buyer or any of its Subsidiaries or afford access to the business,
     properties, assets, books or records of Buyer or any of its Subsidiaries,
     or otherwise cooperate in any way with, or knowingly assist, participate
     in, facilitate or encourage any effort by any person that is seeking to
     make, or has made, an Acquisition Proposal; or

          (iii) grant any waiver or release under any standstill or similar
     agreement with respect to any class of equity securities of Buyer or any of
     its Subsidiaries.

     Notwithstanding the foregoing, prior to the approval of the Buyer Voting
Proposal, Buyer may, to the extent required by the fiduciary duties of the
Buyer's board of directors under applicable law, as determined in good faith by
a majority vote of the Buyer's full board of directors, after consultation with
outside counsel and its financial advisor, in response to an Acquisition
Proposal that did not result from a breach by Buyer of this Section 4.9 (x)
furnish information with respect to Buyer to the person making such an
Acquisition Proposal pursuant to a customary confidentiality agreement not less
restrictive of the other party than the Confidentiality Agreement and (y)
participate in discussions or negotiations with such person and its
representatives regarding any such Acquisition Proposal. Promptly after Buyer's
receipt of any Acquisition Proposal, Buyer shall send Emerson a written notice
advising Emerson of the existence of such Acquisition Proposal and whether such
Acquisition Proposal is, or becomes, contingent on the disapproval of the
transactions contemplated by this Agreement. In addition, Buyer shall notify
Emerson when its board of directors accepts or rejects such Acquisition
Proposal.

     (b) The Buyer's board of directors shall not, except as set forth in this
Section 4.9, withdraw or modify, or propose to withdraw or modify, in a manner
adverse to Emerson, its approval or recommendation with respect to the Buyer
Voting Proposal.

     Notwithstanding the foregoing, the Buyer's board of directors may, in
response to an Acquisition Proposal, withdraw or modify its recommendation with
respect to the Buyer Voting Proposal, if the Buyer's full board of directors
determines by majority vote in good faith (after consultation with outside
counsel and its financial advisor) that its fiduciary duties require it to do
so, but only at a time that is prior to the receipt of the Buyer Requisite Vote.

     (c) Nothing contained in this Section 4.9 shall be deemed to prohibit Buyer
from taking and disclosing to its stockholders a position with respect to a
tender offer contemplated by Rule 14e-2(a) promulgated under the Exchange Act
if, in the good faith judgment of the Buyer's board of directors, failure to so
disclose would be inconsistent with its obligations under applicable law.

     4.10  FIRPTA Tax Certificates.  Within 30 days prior to the Closing,
Emerson will deliver or cause to be delivered, to the Buyer a certification that
Astec America, Inc. is not a foreign person in accordance with the Treasury
Regulations under Section 1445 of the Code. If Astec America, Inc. has not
provided the certification described above to the Buyer on or before the Closing
Date, the Buyer shall be permitted to withhold from the Purchase Price any
required withholding Tax under Section 1445 of the Code.

to execute and deliver the IP License Agreement to Astec International Limited

     representations and warranties are specifically made as of a particular
     date (in which case such representations and warranties shall be true and
     correct as of such date) other than such failures to be true and correct
     that could not reasonably be expected to have, individually or in the
     aggregate, a Company Material Adverse Effect;

          (c) Emerson shall have, or caused its Subsidiaries to have, performed

                                   ARTICLE VI

                             POST-CLOSING COVENANTS

     6.1  Proprietary Information.  From and after the Closing, Emerson shall
not disclose or make use of, and shall use its Reasonable Best Efforts to cause
all of its Affiliates not to disclose or make use of, any knowledge, information
or documents of a confidential nature or not generally known to the public with
respect to the ENI Business, other than Excluded Assets and Excluded
Liabilities, or the Buyer or their respective businesses (including the
financial information, technical information or data relating to the ENI
Business and the ENI Business' products and names of customers), except that
disclosure of such information may be made if and to the extent (a) required by
applicable law or regulation or the rules of any national securities exchange,
or (b) it becomes generally available to the public other than as a result of a
disclosure by Emerson or its representatives, or (c) becomes available to
Emerson on a non-confidential basis from a source other than Buyer or its
representatives, provided that such source is not known by Emerson to be bound
by a confidentiality agreement with or other obligation of secrecy to Buyer or
another person, or (d) was or is independently acquired or developed by Emerson
after the Closing Date without violating any of its obligations under this
Section 6.1 or any other agreement with Buyer.

     6.2  Solicitation and Hiring.  For a period of three years after the
Closing Date, Emerson shall not, either directly or indirectly (including
through an Affiliate), (a) solicit or attempt to induce any Restricted Employee
to terminate his employment with the Buyer or any Subsidiary of the Buyer,
provided that the foregoing will not prevent Emerson or its Affiliates from
making general solicitations of employment not specifically directed towards any
Restricted Employee or (b) hire or attempt to hire any engineers, sales or
marketing employee of the ENI Business, any employee of the ENI Business
employed in the People's Republic of China, or any employee of the ENI Business
whose annual compensation exceeds US$75,000. This Section shall not apply to any
individual whose employment by the Buyer or a Subsidiary of the Buyer has been
terminated by Buyer or such Subsidiary.

                                       A-35


     6.3  Non-Competition.

     (a) Subject to Section 6.3(c) below, for a period of five years after the
Closing Date, Emerson shall not, either directly or indirectly (including
through an Affiliate) as a stockholder, investor, partner, consultant or
otherwise, engage anywhere in the world in the Restricted Business.

     (b) Emerson agrees that the duration and geographic scope of the
non-competition provision set forth in this Section 6.3 are reasonable. In the
event that any court determines that the duration or the geographic scope, or
both, are unreasonable and that such provision is to that extent unenforceable,
the Parties agree that the provision shall remain in full force and effect for
the greatest time period and in the greatest area that would not render it
unenforceable. The Parties intend that this non-competition provision shall be
deemed to be a series of separate covenants, one for each and every county of
each and every state of the United States of America and each and every
political subdivision of each and every country outside the United States of
America where this provision is intended to be effective.

     (c) Nothing in this Section 6.3 shall prohibit Emerson or its Affiliates
from, directly or indirectly, acquiring (a) any company or entity that competes
in the Restricted Business, provided that Emerson or its Affiliates, as
applicable, must as soon as practicable after such acquisition, divest any
interest acquired to the extent that it relates to the Restricted Business, or
(b) up to 5% of the outstanding securities of any publicly traded company.

     6.4  Sharing of Data.  Emerson shall have the right for a period of seven
years following the Closing Date or, in the case of books, records and accounts
relating to Taxes, until thirty (30) days after the expiration of all applicable
statutes of limitations (giving effect to any waiver, extension or mitigation
thereof), to have reasonable access to such books, records and accounts,
including financial and Tax information, correspondence, production records,
employment records and other records pertaining to the ENI Business held by the
Buyer, any Company or any Company Subsidiary for the limited purposes of
concluding its involvement in the ENI Business as conducted by Emerson and the
Existing ENI Subsidiaries prior to the Closing Date and for complying with its
obligations under applicable securities, Tax, environmental, employment or other
laws and regulations. The Buyer shall have the right for a period of seven years
or, in the case of books, records and accounts relating to Taxes, until thirty
(30) days after the expiration of all applicable statutes of limitations (giving
effect to any waiver, extension or mitigation thereof), following the Closing
Date to have reasonable access to those books, records and accounts, including
financial and accounting records (including the work papers of Emerson's, any
Asset Seller's and the Existing ENI Subsidiaries' independent accountants), Tax
records, correspondence, production records, employment records and other
records pertaining to the ENI Business that are retained by Emerson, any Asset
Seller and the Existing ENI Subsidiaries pursuant to the terms of this Agreement
to the extent that any of the foregoing is needed by the Buyer for the purpose
of conducting the ENI Business after the Closing and complying with its
obligations under applicable securities, Tax, environmental, employment or other
laws and regulations. None of the Buyer, Emerson or any of their respective
Subsidiaries shall destroy any such books, records or accounts retained by it
without first providing the other Party with the opportunity to obtain or copy
such books, records, or accounts at such other Party's expense.

     6.5  Cooperation in Litigation.  From and after the Closing Date, each
Party shall fully cooperate in all reasonable requests in connection with the
other in the defense or prosecution of any litigation or proceeding already
instituted or which may be instituted hereafter against or by such other Party
relating to or arising out of the conduct of the ENI Business prior to or after
the Closing Date (other than litigation among the Parties and/or their
Affiliates arising out the transactions contemplated by this Agreement). The
Party requesting such cooperation shall pay the reasonable out-of-pocket
expenses incurred in providing such cooperation (including legal fees and
disbursements) by the Party providing such cooperation and by its officers,
directors, employees and agents, but shall not be responsible for reimbursing
such Party or its officers, directors, employees and agents, for their time
spent in such cooperation.

                                       A-36


     6.6  Employee Benefits.

     (a) From and after the Closing, each employee of ENI US will be paid at
salary rates and employee benefit levels which are comparable in the aggregate
to the salary rates and benefit levels for such employee immediately prior to
Closing. Buyer or its Affiliates will offer employment to any ENI Employee who
is not an employee of ENI US and will offer initial salary rates and employee
benefit levels which are comparable in the aggregate to the salary rates and
benefit levels for such employees immediately prior to Closing, but in the case
of benefit levels, to the extent of those benefits disclosed on Schedule 2.23
with respect to such employees.

     (b) Emerson will fully vest the account balances of each ENI Employee (to
the extent not then fully vested) if any, in Emerson's Savings Programs. As of
the Closing Date, ENI Employees will cease active participation in Emerson's
Savings Programs, and the Buyer will accept cash rollovers into its tax
qualified individual account plan of account balances of any ENI Employee from
said terminated plans.

     (c) Except as agreed by Buyer and Emerson, effective as of the Closing, ENI
Employees shall cease to be active participants in any Employee Benefit Plan
that is not a Stand-Alone Plan. If, after the Closing, Buyer terminates a
Stand-Alone Plan during a contract year and under such Stand-Alone Plan the
participant has been responsible for any co-payments or payment of deductible
amounts during such contract year, then the Buyer shall use its Reasonable Best
Efforts to provide appropriate credit for the Affected Participants under the
terms of any Comparable Plans if the Affected Participants begin participation
after the beginning of the contract year in the Comparable Plans.

     (d) Any severance or other employment termination obligations arising prior
to or as a result of the transactions contemplated by this Agreement (except as
described in the following sentence) shall be the responsibility of Emerson.
Buyer shall be responsible for any severance and other employment termination
obligations arising after the Closing, as well as any such obligations arising
as a result of both (i) the transactions contemplated by this Agreement and (ii)
Buyer's failure to comply with any provision of this Section 6.6, provided that
notwithstanding this sentence or the preceding sentence, Buyer shall be
responsible for one-half of the present value, not to exceed $200,000 in the
aggregate, of any severance benefit of any ENI Employee employed by an Asset
Seller who (i) does not accept an offer of employment which meets the
requirements of Section 6.6(a) and (ii) is entitled to severance benefits solely
because such benefits are required as a matter of applicable law.

     (e) To the extent permitted by law and the terms of the plans, all Buyer's
employee benefit plans will provide service credit (for eligibility and vesting
but not for accrual of benefits under any defined benefit retirement plan) to
the employees of ENI US for all service accrued by them as of the Closing with
Emerson, any Existing ENI Subsidiary, any Company and any Company Subsidiaries.
The Buyer will use Reasonable Best Efforts to effectuate the waiver of any
pre-existing condition exclusions under any of its employees benefit plans
providing health benefits to employees of ENI US.

     (f) With respect to all ENI Employees, the Buyers and its Affiliates will
recognize all accrued and unused vacation days and/or holidays and any personal
and sickness days (i) which have accrued with respect to such ENI Employees
through the Closing, and (ii) the liability for which is included in the amounts
disclosed on Section 2.23(n) of the Disclosure Schedule.

     (g) Without limiting the foregoing, with respect to all ENI Employees based
outside the United States, the Buyer or one of its Affiliates shall adopt or
assume any Stand-Alone Plan, and shall participate in any government-sponsored
or mandated benefits program, as required by applicable law and to the extent
necessary to avoid any deemed or constructive termination of any ENI Employees;
provided that, nothing in this Section 6.6(g) shall require the Buyer or any of
its Affiliates to adopt or assume any Stand-Alone Plan or participate in any
benefits program to the extent such Stand-Alone Plan or benefits program was
either (i) not disclosed to the Buyer on Schedule 2.23, or (ii) not maintained
by the ENI Business for ENI Employees prior to the date of this Agreement.

     6.7  Insurance Matters.  Emerson agrees that it shall, at the request of
Buyer but at no expense to Emerson, assert and diligently pursue covered claims
under any insurance policy maintained by Emerson
                                       A-37


or any of its Affiliates prior to the Closing for damages suffered or losses
incurred by the ENI Business with respect to the operation of the ENI Business
prior to the Closing Date. Emerson shall pay, or cause its insurer to pay, the
Buyer all amounts recovered under any such policy with respect to any such claim
after deduction of Emerson's reasonable costs of collection associated
therewith.

     6.8  Section 338(g) Election.  Buyer shall make, or cause to be made, a
timely and valid election under Section 338(g) of the Code with respect to the
Hong Kong Shares, all the shares of capital stock of ENI Taiwan and ENI China
(in each case, unless it is not treated as a corporation for U.S. federal income
tax purposes) acquired pursuant to this Agreement.

     6.9  Treatment of Merger for Tax Purposes.  It is the intention of each
Party that the Merger qualify as a "reorganization" within the meaning of
Section 368 of the Code and that each of ENI US, the Transitory Subsidiary and
Buyer be treated as parties to the "reorganization" for purposes of Section
368(b) of the Code. No Party or any Affiliate of any Party will take any
position on any United States federal, state, or local income or franchise tax
return, or take any other Tax reporting position, that is inconsistent with the
treatment of the Merger as a reorganization, within the meaning of Section 368
of the Code, unless compelled to do otherwise by the Internal Revenue Service.

                                  ARTICLE VII
                                INDEMNIFICATION

     7.1  Indemnification by Emerson.  Emerson shall indemnify the Buyer and its
Affiliates in respect of, and hold them harmless against, any and all Damages
incurred or suffered by the Buyer, any Company, any Company Subsidiary or any
Affiliate thereof resulting from, relating to or constituting:

          (a) any breach of any representation or warranty of Emerson contained
     in this Agreement; or

          (b) any failure to perform any covenant or agreement of Emerson
     contained in this Agreement.

     7.2  Indemnification by the Buyer.  The Buyer shall indemnify Emerson and
its Affiliates in respect of, and hold them harmless against, any and all
Damages incurred or suffered by Emerson or any Affiliate thereof resulting from,
relating to or constituting:

          (a) any breach of any representation or warranty of the Buyer
     contained in this Agreement;

          (b) any failure to perform any covenant or agreement of the Buyer
     contained in this Agreement; or

          (c) any failure by Buyer, any Affiliate of Buyer, any Company or any
     Company Subsidiary to satisfy when due all Assumed Liabilities (including,
     without limitation, Emerson's guaranty of the IDRB Lease) other than claims
     relating to Environmental Matters and claims for Tax matters, which are
     addressed in Article IX of this Agreement.

     7.3  Indemnification Claims.

     (a) An Indemnified Party shall give prompt written notification to the
Indemnifying Party of the assertion of any claim or the commencement of any
Third Party Action which, if successful, could give rise to a claim for
indemnification under this Agreement (an "Expected Claim Notice"), and shall
describe in reasonable detail (to the extent known by the Indemnified Party) the
facts constituting the basis for such Third Party Action and the amount of the
claimed damages (if known); provided, however, that no delay or failure on the
part of the Indemnified Party in so notifying the Indemnifying Party shall
relieve the Indemnifying Party of any liability or obligation hereunder except
to the extent of any damage or liability caused by or arising out of such
failure. Within 20 days after delivery of such notification, the Indemnifying
Party may, upon written notice thereof to the Indemnified Party, assume control
of the defense of such Third Party Action with counsel reasonably satisfactory
to the Indemnified Party; provided that (i) the Indemnifying Party may only
assume control of such defense if (A) it acknowledges in writing to the
Indemnified Party that any damages, fines, costs or other liabilities that may
be assessed against the Indemnified Party in connection with such Third Party
Action constitute Damages for which
                                       A-38


the Indemnified Party shall be indemnified pursuant to this Article VII and (B)
the ad damnum is less than or equal to the amount of Damages for which the
Indemnifying Party is liable under this Article VII and (ii) the Indemnifying
Party may not assume control of the defense of any Third Party Action involving
criminal liability or in which equitable relief is sought against the
Indemnified Party. If the Indemnifying Party does not, or is not permitted under
the terms hereof to, so assume control of the defense of a Third Party Action,
the Indemnified Party shall control such defense. The Non-controlling Party may
participate in such defense at its own expense. The Controlling Party shall keep
the Non-controlling Party advised of the status of such Third Party Action and
the defense thereof and shall consider in good faith recommendations made by the
Non-controlling Party with respect thereto. The Non-controlling Party shall
furnish the Controlling Party with such information as it may have with respect
to such Third Party Action (including copies of any summons, complaint or other
pleading which may have been served on such party and any written claim, demand,
invoice, billing or other document evidencing or asserting the same) and shall
otherwise cooperate with and assist the Controlling Party in the defense of such
Third Party Action. The fees and expenses of counsel to the Indemnified Party
with respect to a Third Party Action shall be considered Damages for purposes of
this Agreement if (i) the Indemnified Party controls the defense of such Third
Party Action pursuant to the terms of this Section 7.3(a) or (ii) the
Indemnifying Party assumes control of such defense and the Indemnified Party
reasonably concludes that the Indemnifying Party and the Indemnified Party have
conflicting interests or different defenses available with respect to such Third
Party Action. The Indemnifying Party shall not agree to any settlement of, or
the entry of any judgment arising from, any such Third Party Action without the
prior written consent of the Indemnified Party, which shall not be unreasonably
withheld, conditioned or delayed. The Indemnified Party shall not agree to any
settlement of, or the entry of any judgment arising from, any such Third Party
Action without the prior written consent of the Indemnifying Party, which shall
not be unreasonably withheld, conditioned or delayed.

     (b) In order to seek indemnification under this Article VII, an Indemnified
Party shall deliver a Claim Notice to the Indemnifying Party.

     (c) Within 20 days after delivery of a Claim Notice, the Indemnifying Party
shall deliver to the Indemnified Party the Response, in which the Indemnifying
Party shall: (i) agree that the Indemnified Party is entitled to receive all of
the Claimed Amount (in which case the written response shall be accompanied by a
payment by the Indemnifying Party to the Indemnified Party of the Claimed
Amount, by check or by wire transfer), (ii) agree that the Indemnified Party is
entitled to receive the Agreed Amount (in which case the written response shall
be accompanied by a payment by the Indemnifying Party to the Indemnified Party
of the Agreed Amount, by check or by wire transfer) or (iii) dispute that the
Indemnified Party is entitled to receive any of the Claimed Amount. If the
Response creates a Dispute, the Indemnifying Party and the Indemnified Party
shall follow the procedures set forth in Section 7.3(d) for the resolution of
such Dispute.

     (d) During the 30-day period following the delivery of a Response that
reflects a Dispute, the Indemnifying Party and the Indemnified Party shall use
good faith efforts to resolve the Dispute. If the Dispute is not resolved within
such 30-day period, the Indemnifying Party and the Indemnified Party shall
discuss in good faith the submission of the Dispute to an ADR Procedure. In the
event the Indemnifying Party and the Indemnified Party agree upon an ADR
Procedure, such parties shall, in consultation with the ADR Service, promptly
agree upon a format and timetable for the ADR Procedure, agree upon the rules
applicable to the ADR Procedure, and promptly undertake the ADR Procedure. The
provisions of this Section 7.3(d) shall not obligate the Indemnifying Party and
the Indemnified Party to pursue an ADR Procedure or prevent either such party
from pursuing the Dispute in a court of competent jurisdiction; provided that,
if the Indemnifying Party and the Indemnified Party agree to pursue an ADR
Procedure, neither the Indemnifying Party nor the Indemnified Party may commence
litigation or seek other remedies with respect to the Dispute prior to the
completion of such ADR Procedure. Any ADR Procedure undertaken by the
Indemnifying Party and the Indemnified Party shall be considered a compromise
negotiation for purposes of federal and state rules of evidence, and all
statements, offers, opinions and disclosures (whether written or oral) made in
the course of the ADR Procedure by or on

                                       A-39


behalf of the Indemnifying Party, the Indemnified Party or the ADR Service shall
be treated as confidential and, where appropriate, as privileged work product.
Such statements, offers, opinions and disclosures shall not be discoverable or
admissible for any purposes in any litigation or other proceeding relating to
the Dispute (provided that this sentence shall not be construed to exclude from
discovery or admission any matter that is otherwise discoverable or admissible).
The fees and expenses of any ADR Service used by the Indemnifying Party and the
Indemnified Party shall be shared equally by the Indemnifying Party and the
Indemnified Party.

     (e) Notwithstanding the other provisions of this Section 7.3, if a third
party asserts (other than by means of a lawsuit) that an Indemnified Party is
liable to such third party for a monetary or other obligation which may
constitute or result in Damages for which such Indemnified Party may be entitled
to indemnification pursuant to this Article VII, and such Indemnified Party
reasonably determines that it has a valid business reason to fulfill such
obligation, then (i) such Indemnified Party shall be entitled to satisfy such
obligation, without prior notice to or consent from the Indemnifying Party, (ii)
such Indemnified Party may subsequently make a claim for indemnification in
accordance with the provisions of this Article VII, and (iii) such Indemnified
Party shall be reimbursed, in accordance with the provisions of this Article
VII, for any such Damages for which it is entitled to indemnification pursuant
to this Article VII (subject to the right of the Indemnifying Party to dispute
the Indemnified Party's entitlement to indemnification, or the amount for which
it is entitled to indemnification, under the terms of this Article VII, as if
the claim had not been settled).

     (f) With respect to any claims relating to Environmental Matters, Emerson
shall have no liability unless: (i) the Buyer's claim arises from or relates to
actions taken, required to be taken or expenses incurred in order to comply with
Environmental Laws; or (ii) there has been a claim, complaint, request, inquiry,
notice, demand, suit or proceeding made or threatened against Buyer or its
Affiliates by a Governmental Entity or a third party.

     (g) The Buyer shall not be entitled to indemnification for response actions
to address the presence, if any, of Materials of Environmental Concern in the
soil or groundwater at any owned, leased or subleased real property to the
extent that such response actions arise from Buyer's voluntary action which was
taken without an Independent Business Purpose.

     7.4  Survival of Representations and Warranties.  All representations and
warranties contained in this Agreement shall (a) survive the Closing and (b)
shall expire on March 31, 2003, except that (i) the representations and
warranties set forth in Sections 2.1, 2.2, 2.3, 2.4, 2.6, 3.1, 3.2 and 3.3 shall
survive the Closing without limitation, (ii) the representations and warranties
set forth in Sections 2.14 and 2.24 shall survive the Closing for 36 months and
(iii) the representations and warranties set forth in Sections 2.10 and 2.23
shall survive the Closing until 30 days following expiration of all statutes of
limitation applicable to the matters referred to therein. If an Indemnified
Party delivers to an Indemnifying Party, before expiration of a representation
or warranty, either a Claim Notice based upon a breach of such representation or
warranty, or an Expected Claim Notice, then the applicable representation or
warranty shall survive until, but only for purposes of, the resolution of the
matter covered by such notice. If the legal proceeding or written claim with
respect to which an Expected Claim Notice has been given is definitively
withdrawn or resolved in favor of the Indemnified Party, the Indemnified Party
shall promptly so notify the Indemnifying Party. The rights to indemnification
set forth in this Article VII shall not be affected by any investigation
conducted by or on behalf of an Indemnified Party or any knowledge of an
Indemnified Party with respect to the inaccuracy or noncompliance with any
representation, warranty, covenant or obligation which is the subject of
indemnification hereunder.

     7.5  Limitations.

     (a) Notwithstanding anything to the contrary herein, Emerson shall not be
liable under Section 7.1(a) unless and until the aggregate Damages for which it
would otherwise be liable exceed $2,000,000 (at which point Emerson shall become
liable only to the extent of such excess); provided that the foregoing
limitation shall not apply to a claim pursuant to Section 7.1(a) relating to a
breach of the representations and warranties set forth in Sections 2.1, 2.2,
2.3, 2.4 or 2.6, and provided further that
                                       A-40


(i) Emerson shall not be liable pursuant to Section 7.1(a) for any individual
claim that is less than $40,000, (ii) Emerson's maximum liability under this
Article VII shall not exceed $200,000,000 and (iii) Emerson shall not be liable
pursuant to this Article VII (but shall be liable pursuant to Article IX to the
extent provided therein) in respect of any Tax liability that relates to any
taxable period ending (or deemed to end pursuant to Section 9.4(b)) on or before
the Closing Date. Notwithstanding the foregoing, Emerson shall be liable for a
breach of the representation or warranty set forth in Section 2.16(c) hereof for
all Damages in excess of $50,000. In addition, Emerson shall not be liable for
any Damages for a breach of the representation and warranty in the first two
sentences of Section 2.14(c) (or a breach of any representation or warranty in
Article II of this Agreement relating to the subject matter of such first two
sentences of Section 2.14(c)) incurred or suffered by the Buyer or any of its
Affiliates arising from the marketing, distribution, making, provision or use of
any Customer Deliverables after the fifth anniversary of the Closing Date. For
purposes solely of this Article VII, all representations and warranties of

subject matter of this Agreement, except to the extent such damages arise as a
result of, pursuant to, or are asserted as a part of any third party claim.

     7.6  Treatment of Indemnity Payments.  Any payments made to an Indemnified
Party pursuant to this Article VII shall be treated as an adjustment to the
Purchase Price for Tax purposes allocable to the Cash Purchase Price or Merger
Consideration, as appropriate.

                                       A-41


     conditions set forth in clauses (b), (c), (d) or (e) of Section 5.2 not to

     5.2 hereof (unless the failure results primarily from a breach by the Buyer
     of any representation, warranty or covenant contained in this Agreement);

          (f) Emerson may terminate this Agreement by giving written notice to
     the Buyer if the Closing shall not have occurred on or before June 30, 2002
     by reason of the failure of any condition precedent under Section 5.1 or

     or modified, or proposed to withdraw or modify, in a manner adverse to
     Emerson, its approval or recommendation of the Buyer Voting Proposal;

          (h) by the Buyer, if, prior to the Buyer Stockholder Meeting, the

     Buyer Voting Proposal in accordance with Section 4.9; and

          (i) by Emerson, if the Buyer breaches the provisions of Section 4.9
     and an Acquisition Proposal is publicly announced by any party other than

the foregoing, in the event (a) Emerson terminates this Agreement pursuant to
the provisions of Section 8.1(d), Section 8.1(g) or Section 8.1(i), or (b) the
Buyer terminates this Agreement pursuant to the provisions of Section 8.1(d) or
Section 8.1(h) then unless such termination occurs under circumstances under
which the conditions of Section 5.1(b) and Section 5.2 had not been satisfied
and there is no reasonable prospect of such conditions being satisfied, the
Buyer shall pay the Break-up Fee (other than the out-of-pocket expenses which
are to be reimbursed by the Buyer which shall be paid by the Buyer upon
presentation by Emerson of the appropriate documentation) to Emerson within 15
business days in the case of clause (a), or prior to and as a condition to such
termination in the case of clause (b).

     the extent they exceed the reserves and accruals for such Taxes reflected
     on the Statement of Closing Working Capital;

     (b) The Parties agree that to the maximum extent allowable under applicable

     (b) Any Taxes for a taxable period beginning before and ending after the
Closing Date shall be paid by the Buyer and/or any Company and any Company

Taxes that (x) are based upon or related to income or receipts or (y) imposed in
connection with any sale or other transfer or assignment of property, other than
Taxes described in Section 9.2(a)(iii), the amount which would be payable if the
taxable year ended with the Closing Date, and (ii) in the case of other Taxes
imposed on a periodic basis (including property Taxes), the amount of such Taxes
for the entire period multiplied by a fraction the numerator of which is the
number of calendar days in the period ending with the Closing Date and the
denominator of which is the number of calendar days in the entire period. For
purposes of the provisions of Sections 9.2, 9.3 and 9.5, each portion of such

taxable period).

registration, documentary, filing or other similar Taxes and fees, whether
levied on the Buyer, Emerson, or any of their respective Affiliates arising out
of or resulting from this Agreement or any of the transactions contemplated by

responsible for paying such Tax of notice to the other Party that such Tax has
been paid.

any payment for which it is liable under Section 9.2 or Section 9.3 to the Party
responsible for filing such Tax Return under Section 9.1 not later than five
business days prior to the due date for the payment of such Taxes (including

     9.5  Refunds and Carrybacks.

     (a) Emerson shall be entitled to an amount equal to any refunds (including
any interest paid thereon) or credits of Taxes attributable to taxable periods
ending (or deemed pursuant to Section 9.4(b) to end) on or before the Closing
Date, which refunds were treated as Excluded Assets. The Buyer shall promptly
notify Emerson in writing of any Tax refund(s) received by or payable to any
Company or any Company Subsidiary after the Closing in respect of periods before

promptly to forward to or reimburse Emerson for any refunds (including any
interest paid thereon) or credits due Emerson (pursuant to the terms of this
Agreement) after receipt thereof, and Emerson shall promptly forward to the
Buyer or reimburse the Buyer for any refunds (including any interest paid
thereon) or credits due the Buyer after receipt thereof.

before the Closing Date.

     9.6  Cooperation on Tax Matters; Tax Audits.

     (a) The Parties and their respective Affiliates shall cooperate in the
preparation of all Tax Returns for any Tax periods for which one Party could
reasonably require the assistance of the other Party in obtaining any necessary
information. Such cooperation shall include, but not be limited to, furnishing
prior years' Tax Returns or return preparation packages illustrating previous
reporting practices or containing historical information relevant to the
preparation of such Tax Returns, and furnishing such other information within
such Party's possession requested by the Party filing such Tax Returns as is
relevant to their preparation. Such cooperation and information also shall
include without limitation provision of powers of attorney for the purpose of
signing Tax Returns and defending audits and promptly forwarding copies of
appropriate notices and forms or other communications received from or sent to
any Taxing Authority, and providing copies of all relevant Tax Returns, together
with accompanying schedules and related work papers, documents relating to
rulings or other determinations by any Taxing Authority and records concerning
the ownership and Tax basis of property, which the requested Party may possess.
The Parties and their respective Affiliates shall make their respective
employees and facilities available on a mutually convenient basis to explain any
documents or information provided hereunder.

     (b) Emerson shall have the right, at its own expense, to control any Tax
Audit, initiate any claim for refund, contest, resolve and defend against any
assessment, notice of deficiency, or other adjustment or proposed adjustment
relating to any and all Taxes for which it is liable under Section 9.3(a) for
any taxable period ending on or before the Closing Date with respect to any
Company and any Company Subsidiary. The Buyer shall have the right, at its own
expense, to control any other Tax Audit, initiate any other claim for refund,
and contest, resolve and defend against any other assessment, notice of
deficiency, or other adjustment or proposed adjustment relating to Taxes with
respect to any Company and any Company Subsidiary; provided that, with respect
to (i) any state, local or foreign Taxes for any taxable period beginning before
the Closing Date and ending after the Closing Date and (ii) any item the
adjustment of which may cause Emerson to become obligated to make any payment
pursuant to Section 9.2(a) hereof, the Buyer shall consult with Emerson with
respect to the resolution of any issue that would affect Emerson, and not settle
any such issue, or file any amended Tax Return relating to such issue, without
the consent of Emerson, which consent shall not unreasonably be withheld. Where
consent to a settlement is withheld by Emerson pursuant to this Section, Emerson
may continue or initiate any further proceedings at its own expense, provided
that any liability of the Buyer, after giving effect to this Agreement, shall
not exceed the liability that would have resulted had Emerson not withheld its
consent.

similar arrangements with respect to or involving any Company or any Company
Subsidiary shall be terminated prior to the Closing Date and, after the Closing

liability thereunder.

if within 10 days after receipt of a request, therefor the Company provides
written notice of its bona fide intention to file within 60 days a registration

during the period from the date of filing of, and ending 90 days after the
effective date of, any registration statement for an underwritten public
offering of securities for the account of the Company. In no event shall the

register more than (i) four million Shares prior to the date that is one year

Shares registered under clause (i) and (ii)) prior to the date that is three
years after the expiration of the Lock-Up Period; provided that any of the
numbers shall be adjusted (x) based on the number of Shares in excess of twelve
million Shares delivered by the Company to Emerson and its Subsidiaries at the
Closing Date, (y) based on any Adjustment Event that occurs after the Closing
Date but before the effective date of the relevant Demand Registration, and (z)
if Emerson requests, and the Company consents, to increase the numbers in the
foregoing limitations (such consent not to be unreasonably withheld, where it
will be reasonable for the Company to refuse such consent if it would be
reasonably expected to have an adverse effect on the trading price of the
Shares), the numbers in clause (b)(i) and (b)(ii) above shall be increased by no
more than four million Shares multiplied by the proportion of the year that has
passed (as of the date of the request) from the date that is one year and two
years respectively after the expiration of the Lock-Up Period provided further
that the limitations described in Sections 5.01(a)(ii), (vii) and (viii), this
Section 5.01(b) and the proviso in Section 5.04(a) shall not apply if Emerson's
Common Stock Interest is equal to or greater than 12.5% and notwithstanding that
the Company has fully performed its obligations under Article 2: (A) Emerson
designates a representative to serve on the Board in accordance with Section
2.01 of this Agreement and such designee is not elected or appointed to the
Board for any reason, or (B) Emerson's representative on the Board is removed

and any additional investment bankers and managers to be used, in connection
with the offering resulting from a request for a Demand Registration made
pursuant to Section 5.01(a), subject to the Company's reasonable approval (such
approval not to be unreasonably withheld).

     SECTION 5.02.  Piggyback Registration.  If the Company proposes to register
any Shares, whether for sale for its own account or for the account of any of
its holders of Shares, the Company shall each such time give prompt notice to
Emerson at least 15 Business Days prior to the anticipated filing date of the
registration statement relating to such registration, which notice shall set
forth Emerson's rights under this Section 5.02 and shall offer Emerson and its
Subsidiaries the opportunity to register such number of shares of Registrable
Securities as Emerson may request on the same terms and conditions as the
Company or such holder of Shares (a "PIGGYBACK REGISTRATION"); provided, that
Emerson shall not request the registration of a greater number of Shares than
that for which it could then demand a registration under Section 5.01(b). No
registration effected under this Section 5.02 shall relieve the Company of its
obligations to effect a Demand Registration to the extent required by Section
5.01,

                                       A-65


provided, however, that any Shares sold pursuant to this Section 5.02 shall be
applied against the limitation set forth in Section 5.01(b).

     Notwithstanding anything to the contrary herein, Emerson shall have no
Piggyback Registration rights under this Section 5.02 with respect to a
Registration Statement filed to sell Shares solely for the account of Mr. or
Mrs. John R. Bertucci (or trusts established by either of them) at any time
within 12 months after the death of Mr. and Mrs. Bertucci.

     SECTION 5.03.  Reduction of Offering.  Notwithstanding anything contained
herein, if the managing underwriter of an offering described in Section 5.01 or
Section 5.02 advises the Company in writing that (i) the size of the offering
that Emerson, the Company and any other Persons intend to make or (ii) the
combination of securities that Emerson, the Company and such other Persons
intend to include in such offering would jeopardize the success of the offering,
then (A) if the size of the offering is the basis of such underwriter's advice,
the amount of Registrable Securities to be offered for the account of Emerson
shall be reduced to the extent necessary to reduce the total amount of
securities to be included in such offering to the amount recommended by such
managing underwriter; provided that (x) in the case of a Demand Registration,
the amount of Registrable Securities to be offered for the account of Emerson
shall be reduced only after the amount of securities to be offered for the
account of the Company and such other Persons has been reduced to zero, and (y)
in the case of a Piggyback Registration, if securities are being offered for the
account of Persons other than the Company, then the proportion by which the
amount of such Registrable Securities intended to be offered for the account of
Emerson is reduced shall not exceed the proportion by which the amount of such
securities intended to be offered for the account of such other Persons is
reduced, provided that in the case of a Piggyback Registration filed pursuant to
the exercise of demand registration rights by a Person other than Emerson,
Registrable Securities shall be included only if there is no reduction in the
amount of securities registered for the account of the Persons demanding such
registration; and (B) if the combination of securities to be offered is the
basis of such underwriter's advice, (x) the Registrable Securities to be
included in such offering shall be reduced as described in clause (A) above
(subject to the proviso in clause (A)), and (y) in the case of a Piggyback
Registration, if the actions described in sub-clause (x) of this clause (B)
would, in the judgment of the managing underwriter, be insufficient
substantially to eliminate the adverse effect that inclusion of the Registrable
Securities requested to be included would have on such offering, such
Registrable Securities will be excluded from such offering.

     SECTION 5.04.  Filings; Information.  Whenever Emerson requests that any
Registrable Securities be registered pursuant to Section 5.01 hereof, the
Company will use Reasonable Best Efforts to effect the registration of such
Registrable Securities as soon as is practicable, and in connection with any
such request:

          (a) The Company will use its Reasonable Best Efforts to prepare and
     file with the SEC as soon as practicable a Registration Statement on any
     form for which the Company then qualifies and which counsel for the Company
     shall deem appropriate and available for the sale of the Registrable
     Securities to be registered thereunder in accordance with the intended
     method of distribution thereof, and use Reasonable Best Efforts to cause
     such filed Registration Statement to become and remain effective for a
     period as is reasonably required to effect the proposed distribution of the
     Registrable Securities (but in any event, not less than 90 days); provided
     that, subject to the second proviso in Section 5.01(b), the Company's
     obligations to use Reasonable Best Efforts to file the Registration
     Statement shall be suspended for up to 90 days if the Company shall furnish
     to Emerson a certificate signed by the Company's Chief Executive Officer
     stating that in his reasonable good faith judgment the fulfillment of the
     foregoing obligations would (i) require the Company to make a disclosure
     that would be detrimental to the Company and premature, or (ii) occur at a
     time when the price or exchange ratio at which the Company is obligated to
     issue securities (other than Company employee or officer and director stock
     options or restricted stock grants) is being determined, except that the
     foregoing obligations of the Company shall be reinstated upon the making of
     such disclosure by the Company or expiration or termination of the
     circumstances referred to in clause (ii) above (or, if

                                       A-66


     earlier, when such disclosure would no longer be necessary for the
     fulfillment of the foregoing obligations or no longer be detrimental).

          (b) The Company will, if requested, prior to filing such Registration
     Statement or any amendment or supplement thereto, furnish to Emerson and
     each applicable managing underwriter, if any, copies thereof, and
     thereafter furnish to Emerson and each such underwriter, if any, such
     number of copies of such Registration Statement, amendment and supplement
     thereto (in each case including all exhibits thereto and documents
     incorporated by reference therein) and the prospectus included in such
     Registration Statement (including each preliminary prospectus) as Emerson
     or each such underwriter may reasonably request in order to facilitate the
     sale of the Registrable Securities.

          (c) After the filing of the Registration Statement, the Company will
     promptly notify Emerson of any stop order issued or, to the Company's
     knowledge, threatened to be issued by the SEC and take all reasonable
     actions required to prevent the entry of such stop order or to remove it if
     entered.

          (d) The Company will use Reasonable Best Efforts to qualify the
     Registrable Securities for offer and sale under such other securities or
     blue sky laws of such jurisdiction in the United States as Emerson
     reasonably requests; provided that the Company will not be required to (i)
     qualify generally to do business in any jurisdiction where it would not
     otherwise be required to qualify but for this Section 5.04(d), (ii) subject
     itself to taxation in any such jurisdiction or (iii) consent to general
     service of process in any such jurisdiction.

          (e) The Company will as promptly as is practicable notify Emerson, at
     any time when a prospectus relating to the sale of the Registrable
     Securities is required by law to be delivered in connection with sales by
     an underwriter or dealer, of the occurrence of any event requiring the
     preparation of a supplement or amendment to such prospectus so that, as
     thereafter delivered to the purchasers of such Registrable Securities, such
     prospectus will not contain an untrue statement of a material fact or omit
     to state any material fact required to be stated therein or necessary to
     make the statements therein, in the light of the circumstances under which
     they were made, not misleading and promptly make available to Emerson and
     to the underwriters any such supplement amendment. Emerson agrees that,
     upon receipt of any notice from the Company of the occurrence of any event
     of the kind described in the preceding sentence, Emerson will forthwith
     discontinue the offer and sale of Registrable Securities pursuant to the
     Registration Statement covering such Registrable Securities until receipt
     by Emerson and the underwriters of the copies of such supplemented or
     amended prospectus and, if so directed by the Company, Emerson will deliver
     to the Company all copies, other than permanent file copies then in
     Emerson's possession, of the most recent prospectus covering such
     Registrable Securities at the time of receipt of such notice. In the event
     the Company shall give such notice, the Company shall extend the period
     during which such Registration Statement shall be maintained effective as
     provided in Section 5.04(a) hereof by the number of days during the period
     from and including the date of the giving of such notice to the date when
     the Company shall make available to Emerson such supplemented or amended
     prospectus.

          (f) The Company will enter into customary agreements (including an
     underwriting agreement in customary form) and take such other actions as
     are reasonably required in order to expedite or facilitate the sale of such
     Registrable Securities, including but not limited to attendance by the
     Company's Chief Executive Officer and any other Company officers as may be
     reasonably requested by Emerson, at any analyst or investor presentation or
     any "road shows" undertaken in connection with the marketing or selling of
     the Registrable Securities provided that the Company's Chief Executive
     Officer and such Company officers (if any) shall not be required to
     participate in any such presentations or "road show" for more than three
     Business Days in connection with each Demand Registration.

          (g) The Company will furnish to each underwriter (i) an opinion or
     opinions of counsel to the Company and (ii) a comfort letter or comfort
     letters from the Company's independent public accountants, each in
     customary form and covering such matters of the type customarily covered by
     opinions or comfort letters, as the case may be, as the managing
     underwriter reasonably requests.
                                       A-67


          (h) The Company will make generally available to its security holders,
     as soon as reasonably practicable, an earnings statement covering a period
     of 12 months, beginning within three months after the effective date of the
     Registration Statement, which earnings statement shall satisfy the
     provisions of Section 11(a) of the Securities Act and the rules and
     regulations of the SEC thereunder.

          (i) The Company will use Reasonable Best Efforts to (i) to secure the
     designation of all such Registrable Securities covered by such Registration
     Statement as a NASDAQ "national market system security" within the meaning
     of Rule 11Aa2-1 of the SEC or, failing that, to secure NASDAQ authorization
     for such Registrable Securities, in each case if the Registrable Securities
     so qualify, and, without limiting the generality of the foregoing, to
     arrange for at least two market makers to register as such with respect to
     such Registrable Securities with the NASD, or (ii) to cause all Registrable
     Securities covered by such Registration Statement to be listed on any
     national securities exchange (if such Registrable Securities are not
     already listed), and on each other securities exchange on which similar
     securities issued by the Company are then listed, if the listing of such
     Registrable Securities is then permitted under the rules of such exchange.

     The Company may require Emerson promptly to furnish in writing to the
Company such information regarding Emerson, the plan of distribution of the
Registrable Securities and such other information as the Company may from time
to time reasonably request or as may be legally required in connection with such
registration.

     SECTION 5.05.  Registration Expenses.  In connection with any Demand
Registration and in connection with any Piggyback Registration, the Company
shall pay the following expenses incurred in connection with such registration:
(i) registration and filing fees with the SEC, (ii) fees and expenses of
compliance with securities or blue sky laws (including reasonable fees and
disbursements of counsel in connection with blue sky qualifications of the
Registrable Securities), (iii) expenses in connection with the preparation,
printing, mailing and delivery of any registration statements, prospectuses and
other documents in connection therewith and any amendments or supplements
thereto, (iv) fees and expenses incurred in connection with the listing of the
Registrable Securities, (v) fees and expenses of counsel and independent
certified public accountants for the Company, (vi) the reasonable fees and
expenses of any additional experts retained by the Company in connection with
such registration, (vii) internal expenses of the Company (including, without
limitation, all salaries and expenses of its officers and employees performing
legal or accounting duties), (viii) for any Piggyback Registration fees and
expenses in connection with any review by the NASD of the underwriting
arrangements or other terms of the offering, and all fees and expenses of any
"qualified independent underwriter," including the fees and expenses of any
counsel thereto, (ix) costs of printing and producing any agreements among
underwriters, underwriting agreements, any "blue sky" or legal investment
memoranda and any selling agreements and other documents in connection with the
offering, sale or delivery of the Registrable Securities, (x) transfer agents'
and registrars' fees and expenses and the fees and expenses of any other agent
or trustee appointed in connection with such offering, (xi) expenses incurred by
the Company in connection with any analyst or investor presentations or any
"road shows" attended by the Company in connection with the registration,
marketing or selling of the Registrable Securities, and (xii) fees and expenses
payable in connection with any ratings of the Registrable Securities, including
expenses relating to any presentations to rating agencies; provided, however,
that the Company shall not be required to pay, and Emerson shall reimburse the
Company for, any such expenses for any Demand Registration that is withdrawn at
the request of Emerson unless such withdrawn Registration Statement is counted
toward the maximum number of Demand Registrations to which Emerson is entitled
under Section 5.01. Emerson shall pay any underwriting fees, discounts or
commissions attributable to the sale of Registrable Securities and any out-
of-pocket expenses of Emerson.

     SECTION 5.06.  Indemnification by the Company.  The Company agrees to
indemnify and hold harmless Emerson, its officers, directors, employees, and
agents, and each Person, if any, who controls Emerson within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act from and
against any and all losses, claims, damages, liabilities and expenses (including
reasonable expenses of
                                       A-68


investigation and reasonable attorneys' fees and expenses) ("DAMAGES") caused by
or relating to any untrue statement or alleged untrue statement of a material
fact contained in any registration statement or prospectus relating to the
Registrable Securities (as amended or supplemented if the Company shall have
furnished any amendments or supplements thereto) or any preliminary prospectus
(including documents incorporated by reference therein), or caused by or
relating to any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, except insofar as such Damages are caused by or related to any such
untrue statement or omission or alleged untrue statement or omission so made
based upon information furnished in writing to the Company by Emerson or on
Emerson's behalf expressly for use therein, provided that, with respect to any
untrue statement or omission or alleged untrue statement or omission made in any
preliminary prospectus, or in any prospectus, as the case may be, the indemnity
agreement contained in this paragraph shall not apply to the extent that any
Damages result from the fact that a current copy of the prospectus (or such
amended or supplemented prospectus, as the case may be) was not sent or given to
the Person asserting any such Damages at or prior to the written confirmation of
the sale of the Registrable Securities concerned to such Person if it is
determined that the Company has provided such prospectus to Emerson and it was
the responsibility of Emerson to provide such Person with a current copy of the
prospectus (or such amended or supplemented prospectus, as the case may be) and
such current copy of the prospectus (or such amended or supplemented prospectus,
as the case may be) would have cured the defect giving rise to such Damages. The
Company also agrees to indemnify any underwriters of the Registrable Securities,
their officers and directors and each Person who controls such underwriters
within the meaning of Section 15 of the Securities Act or Section 20 of the
Exchange Act on substantially the same basis as that of the indemnification of
Emerson provided in this Section 5.06.

     SECTION 5.07.  Indemnification by Emerson.  Emerson agrees to indemnify and
hold harmless the Company, its officers, directors and agents and each Person,
if any, who controls the Company within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act to the same extent as the
foregoing indemnity from the Company to Emerson, but only (i) with respect to
information furnished in writing by Emerson or on Emerson's behalf expressly for
use in any registration statement or prospectus relating to the Registrable
Securities, or any amendment or supplement thereto, or any preliminary
prospectus or (ii) to the extent that any Damages result from the fact that a
current copy of the prospectus (or such amended or supplemented prospectus, as
the case may be) was not sent or given to the Person asserting any such Damages
at or prior to the written confirmation of the sale of the Registrable
Securities concerned to such Person if it is determined that it was the
responsibility of Emerson to provide such Person with a current copy of the
prospectus (or such amended or supplemented prospectus, as the case may be) and
such current copy of the prospectus (or such amended or supplemented prospectus,
as the case may be) would have cured the defect giving rise to such loss, claim,
damage, liability or expense. Emerson also agrees to indemnify and hold harmless
underwriters of the Registrable Securities, their officers and directors and
each Person who controls such underwriters within the meaning of either Section
15 of the Securities Act or Section 20 of the Exchange Act on substantially the
same basis as that of the indemnification of the Company provided in this
Section 5.07. As a condition to including Registrable Securities in any
registration statement filed in accordance with Article 5, the Company may
require that it shall have received an undertaking reasonably satisfactory to it
from any underwriter to indemnify and hold it harmless to the extent customarily
provided by underwriters with respect to similar securities. Emerson shall not
be liable under this Section 5.07 for any Damages in excess of the net proceeds
realized by Emerson in the sale of Registrable Securities of Emerson to which
such Damages relate.

     SECTION 5.08.  Conduct of Indemnification Proceedings.  If any proceeding
(including any governmental investigation) shall be instituted involving any
Person in respect of which indemnity may be sought pursuant to this Article 5,
such Person (an "INDEMNIFIED PARTY") shall promptly notify the Person against
whom such indemnity may be sought (the "INDEMNIFYING PARTY") in writing and the
Indemnifying Party shall assume the defense thereof, including the employment of
counsel reasonably satisfactory to such Indemnified Party, and shall assume the
payment of all fees and expenses, provided that the failure of any Indemnified
Party so to notify the Indemnifying Party shall not relieve the Indemnifying
Party of its
                                       A-69


obligations hereunder except to the extent that the Indemnifying Party is
materially prejudiced by such failure to notify. In any such proceeding, any
Indemnified Party shall have the right to retain its own counsel, but the fees
and expenses of such counsel shall be at the expense of such Indemnified Party
unless (i) the Indemnifying Party and the Indemnified Party shall have mutually
agreed to the retention of such counsel or (ii) in the reasonable judgment of
such Indemnified Party representation of both parties by the same counsel would
be inappropriate due to actual or potential differing interests between them. It
is understood that, in connection with any proceeding or related proceedings in
the same jurisdiction, the Indemnifying Party shall not be liable for the
reasonable fees and expenses of more than one separate firm of attorneys (in
addition to any local counsel) at any time for all such Indemnified Parties, and
that all such fees and expenses shall be reimbursed as they are incurred. In the
case of any such separate firm for the Indemnified Parties, such firm shall be
designated in writing by the Indemnified Parties. The Indemnifying Party shall
not be liable for any settlement of any proceeding effected without its written
consent, but if settled with such consent, or if there be a final judgment for
the plaintiff, the Indemnifying Party shall indemnify and hold harmless such
Indemnified Parties from and against any loss or liability (to the extent stated
above) by reason of such settlement or judgment. Without the prior written
consent of the Indemnified Party, no Indemnifying Party shall effect any
settlement of any pending or threatened proceeding in respect of which any
Indemnified Party is or could have been a party and indemnity could have been
sought hereunder by such Indemnified Party, unless such settlement includes an
unconditional release of such Indemnified Party from all liability arising out
of such proceeding.

     SECTION 5.09.   Contribution.  If the indemnification provided for in this
Article 5 is unavailable to the Indemnified Parties in respect of any Damages,
then each such Indemnifying Party, in lieu of indemnifying such Indemnified
Party, shall contribute to the amount paid or payable by such Indemnified Party
as a result of such Damages in such proportion as is appropriate to reflect the
relative fault of the Company, Emerson and the underwriters in connection with
the statements or omissions that resulted in such Damages, as well as any other
relevant equitable considerations. The relative fault of the Company, Emerson
and the underwriters shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by such party and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.

     The Company and Emerson agree that it would not be just and equitable if
contribution pursuant to this Section 5.09 were determined by pro rata
allocation (even if the underwriters were treated as one entity for such
purpose) or by any other method of allocation that does not take account of the
equitable considerations referred to in the immediately preceding paragraph.
Notwithstanding the provisions of this Article 5, no underwriter shall be
required to contribute any amount in excess of the amount by which the total
price at which the securities underwritten by it and distributed to the public
were offered to the public exceeds the amount of any Damages which such
underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission, and Emerson shall not
be required to contribute any amount in excess of the amount by which the net
proceeds of the offering (before deducting expenses) received by Emerson exceeds
the amount of any Damages which Emerson has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission. No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any Person who was not guilty of such fraudulent misrepresentation.

     SECTION 5.10.   Other Indemnification.  Indemnification similar to that
specified herein (with appropriate modifications) shall be given by the Company
and Emerson with respect to any required registration or other qualification of
securities under any federal or state law or regulation or governmental
authority other than the Securities Act.

                                       A-70


                                   ARTICLE 6

                        CERTAIN COVENANTS AND AGREEMENTS

     SECTION 6.01.   Rule 144.  The Company covenants that it will file any
reports required to be filed by it under the Securities Act and the Exchange Act
and that it will take such further action as Emerson may reasonably request to
the extent required from time to time to enable Emerson or its Subsidiaries to
sell Registrable Securities without registration under the Securities Act within
the limitation of the exemptions provided by Rule 144 under the Securities Act,
as such Rule may be amended from time to time, or any similar rule or regulation
hereafter adopted by the SEC. Upon the request of Emerson, the Company will
deliver to Emerson a written statement as to whether it has complied with such
reporting requirements.

     SECTION 6.02.   Participation in Public Offering.  Emerson may not
participate in any Public Offering hereunder unless Emerson (a) agrees to sell
its Registrable Securities on the basis provided in any underwriting
arrangements approved by the Persons entitled hereunder to approve such
arrangements and (b) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents reasonably
required under the terms of such underwriting arrangements and the provisions of
this Agreement in respect of registration rights.

     SECTION 6.03.   Consolidation or Merger of the Company.  If the Company
considers any transaction in which the Company consolidates or merges with or
into any Person, as a result of which the Shares are converted into or become,
in whole or in part, securities of any other Person ("SUCCESSOR ENTITY"), the
Company shall use its best efforts to cause the Successor Entity to agree with
Emerson to file a registration statement under the Securities Act covering the
resale of all of the securities issued by the Successor Entity with respect to
the Registrable Securities in such merger or consolidation (and any other
securities issued or issuable in respect of such securities by way of
conversion, exchange, stock dividend, split or combination, recapitalization,
merger, consolidation, other reorganization or otherwise) (collectively, the
"NEW REGISTRABLE SECURITIES") during the period commencing as soon as
practicable after the closing of such merger or consolidation and ending on the
first anniversary thereof, provided, however, that (a) the Successor Entity
shall not be required to register New Registrable Securities to the extent it
conflicts with other pre-existing contractual rights to which the Successor
Entity is a party, and (b) such registration obligation shall be subject to
reasonable customary deferral and suspension periods. Emerson agrees to
cooperate in executing and delivering any agreement reasonably necessary to
implement such registration rights. Notwithstanding the foregoing, the Company
shall not be required to use its best efforts to cause the Successor Entity to
grant any such registration rights if (i) Emerson would be able to sell all of
the New Registrable Securities within the 12-month period following the closing
of such merger or consolidation pursuant to the provisions of Rule 144 (based on
the combined (at the applicable exchange ratio) outstanding shares and combined
(at the applicable exchange ratio) average weekly trading volumes of the Company
and the Successor Entity during the three months prior to the Closing), or (ii)
Emerson, in the opinion of its counsel, would not be considered an affiliate of
the Company for purposes of Rule 145 under the Securities Act if its designee
were to resign as a Director prior to mailing of proxy materials to the
Company's stockholders with respect to such transaction and Emerson is given
sufficient notice to be able to consider and take such action.

                                   ARTICLE 7

                                 MISCELLANEOUS

     SECTION 7.01.  Binding Effect; Assignability; Benefit.  (a) This Agreement
shall inure to the benefit of and be binding upon the parties hereto and their
respective heirs, successors, legal representatives and permitted assigns,
provided that no party may assign, delegate or otherwise transfer any of its
rights or obligations under this Agreement without the prior consent of the
other party hereto. Without limiting the foregoing, (i) Emerson and its
subsidiaries shall not sell or otherwise transfer any of the Shares to any
Subsidiary or Affiliate unless the transferee agrees in writing to be bound by
the provisions of Article 3

                                       A-71


and Article 4 hereof to the same extent as Emerson, and (ii) the provisions of
Articles 2 and 5 are not assignable under any circumstances except to any
Affiliate or Subsidiary of Emerson.

     (b) Nothing in this Agreement, expressed or implied, is intended to confer
on any Person other than the parties hereto, and their respective heirs,
successors, legal representatives and permitted assigns, any rights, remedies,
obligations or liabilities under or by reason of this Agreement.

     SECTION 7.02.  Notices.  All notices, requests and other communications to

Board of Directors
MKS Instruments, Inc.
Six Shattuck Road
Andover, Massachusetts 01810

Members of the Board of Directors:

     MKS Instruments, Inc., a Massachusetts corporation (the "Acquiror"), and
Emerson Electric Co., a Missouri corporation (the "Seller"), propose to enter
into an Agreement and Plan of Merger (the "Merger Agreement") pursuant to which
the Acquiror will agree to acquire from the Seller and certain of the Seller's
subsidiaries (i) via a merger (the "Merger"), all of the issued and outstanding
shares of capital stock (the "ENI US Shares") of ENI Technology, Inc., a
Delaware corporation and a wholly owned subsidiary of the Seller ("ENI US"),
(ii) via a stock purchase (the "Stock Purchase"), all of the issued and
outstanding shares of capital stock (the "ENI HK Shares") of ENI Hong Kong, a
corporation to be organized under the laws of Hong Kong ("ENI Hong Kong") and
(iii) via an asset purchase (the "Asset Purchase"), all of the assets used
(other than those used only tangentially) (the "Acquired Assets") by each of (A)
Astec Germany GmbH, a corporation organized under the laws of Germany ("Astec
Germany") and (B) ENI Japan Limited, a corporation organized under the laws of
Japan ("ENI Japan"), in connection with the ENI Business (as defined in the
Merger Agreement), in consideration for the issuance by the Acquiror to the
Seller of twelve million (12,000,000) shares of common stock, no par value per
share, of the Acquiror (the "Acquiror Common Stock") and the assumption by the
Acquiror of the Assumed Liabilities (as defined in the Merger Agreement)
(collectively, the "Transaction Consideration").

     For purposes hereof, (a) ENI US, ENI Hong Kong, Astec Germany and ENI Japan
are hereinafter referred to collectively as the "ENI Business," (b) the ENI US
Shares and the ENI HK Shares are hereinafter referred to collectively as the
"Company Shares" and (c) the Merger, the Stock Purchase and the Asset Purchase
are hereinafter referred to collectively as the "Transaction."

     You have asked us whether, in our opinion, the issuance by the Acquiror to
the Seller of the Transaction Consideration in exchange for the Company Shares
and the Acquired Assets is fair from a financial point of view to the Acquiror.

     In arriving at the opinion set forth below, we have, among other things:

     (1)  Reviewed certain publicly available business and financial information
          relating to the Acquiror and the ENI Business that we deemed to be
          relevant;

     (2)  Reviewed certain information, including financial forecasts, relating
          to the business, earnings, cash flow, assets, liabilities and
          prospects of the ENI Business and the Acquiror, furnished to, or
          discussed with, us by the Seller, the ENI Business and the Acquiror,
          respectively;

     (3)  Conducted discussions with members of senior management and
          representatives of the Seller, the ENI Business and the Acquiror
          concerning the matters described in clauses 1 and 2 above,

                                       B-1

[Merrill Lynch Logo]

          as well as their respective businesses and prospects before and after
          giving effect to the Transaction;

     (4)  Reviewed the market prices and valuation multiples for the Acquiror
          Common Stock and compared it with those of certain publicly traded
          companies that we deemed to be relevant;

     (5)  Reviewed the results of operations of the ENI Business and the
          Acquiror and compared them with those of certain publicly traded
          companies that we deemed to be relevant;

     (6)  Compared the proposed financial terms of the Transaction with the
          financial terms of certain other transactions that we deemed to be
          relevant;

     (7)  Participated in certain discussions and negotiations among
          representatives of the Seller, the ENI Business and the Acquiror and
          their financial and legal advisors;

     (8)  Reviewed the potential pro forma impact of the Transaction;

     (9)  Reviewed a draft dated October 30, 2001, of the Merger Agreement; and

     (10) Reviewed such other financial studies and analyses and took into
          account such other matters as we deemed necessary, including our
          assessment of general economic, market and monetary conditions.

     In preparing our opinion, we have assumed and relied on the accuracy and
completeness of all information supplied or otherwise made available to us,
discussed with or reviewed by or for us, or publicly available, and we have not
assumed any responsibility for independently verifying such information or
undertaken an independent evaluation or appraisal of any of the assets,
properties or liabilities of the ENI Business or the Acquiror or been furnished
with any such evaluation or appraisal. In addition, we have not assumed any
obligation to conduct any physical inspection of the assets, properties or
facilities of the ENI Business or the Acquiror. With respect to the financial
forecast information furnished to or discussed with us by the Seller, the ENI
Business or the Acquiror, we have assumed that they have been reasonably
prepared and reflect the best currently available estimates and judgment of the
Seller's, the ENI Business' or the Acquiror's management as to the expected
future financial performance of the ENI Business or the Acquiror, as the case
may be. We have further assumed that the Transaction will be accounted for using
the new purchase accounting guidelines under generally accepted accounting
principles and that it will qualify as a tax-free reorganization for U.S.
federal income tax purposes (and also will have certain other tax effects
outside of the United States). We also have assumed that the final form of the
Merger Agreement will be substantially similar to the last draft reviewed by us.

     Our opinion is necessarily based upon market, economic and other conditions
as they exist and can be evaluated on, and on the information made available to
us as of, the date hereof. We have assumed that in the course of obtaining the
necessary regulatory or other consents or approvals (contractual or otherwise)
for the Transaction, no restrictions, including any divestiture requirements or
amendments or modifications, will be imposed that will have a material adverse
effect on the contemplated benefits of the Transaction.

     We are acting as financial advisor to the Acquiror in connection with the
Transaction and will receive a fee from the Acquiror for our services, a
significant portion of which is contingent upon the consummation of the
Transaction. In addition, the Acquiror has agreed to indemnify us for certain
liabilities arising out of our engagement. We are currently and have, in the
past, provided financial advisory and financing services to the Acquiror and may
continue to do so and have received, and may receive, fees for the rendering of
such services. In addition, in the ordinary course of our business, we may
actively trade the Acquiror Common Stock, the common stock of the Seller and
other securities of the Seller, for

                                       B-2

[Merrill Lynch Logo]

our own account and for the accounts of customers and, accordingly, may at any
time hold a long or short position in such securities.

     This opinion is for the use and benefit of the Board of Directors of the
Acquiror. Our opinion does not address the merits of the underlying decision by
the Acquiror to engage in the Transaction and does not constitute a
recommendation to any shareholder of the Acquiror as to how such shareholder
should vote on the proposed Transaction or any matter related thereto.

     We are not expressing any opinion herein as to the prices at which shares
of the Acquiror Common Stock will trade following the announcement or
consummation of the Transaction.

     On the basis of and subject to the foregoing, we are of the opinion that,
as of the date hereof, the issuance by the Acquiror to the Seller of the
Transaction Consideration in exchange for the Company Shares and the Acquired
Assets is fair from a financial point of view to the Acquiror.

                                          Very truly yours,

                                          MERRILL LYNCH, PIERCE, FENNER & SMITH
