Dear AMETEK, Inc. Stockholder:                               June   , 1997     
   
  You are cordially invited to attend a Special Meeting in lieu of the Annual
Meeting of Stockholders of AMETEK, Inc. ("AMETEK") to be held on July 23, 1997
at the Desmond Great Valley Hotel and Conference Center, One Liberty
Boulevard, Malvern, Pennsylvania 19355 at 2:00 p.m. local time.     
   
  On February 4, 1997, the Board of Directors of AMETEK approved the merger of
the water filtration business of AMETEK, which consists of the Plymouth
Products Division, and the following three foreign subsidiaries of AMETEK:
Ametek Filters, Limited, APIC International S.A. and AFIMO S.A.M.
(collectively, the "Water Filtration Business"), with Culligan Water
Technologies, Inc. ("Culligan") in a transaction representing a combined value
in debt and equity of approximately $       at June  , 1997.     
 
  The transaction will occur in two steps. First, AMETEK will distribute to
its stockholders on a share for share basis (the "Spin-Off") all of the shares
of a subsidiary, Ametek Aerospace Products, Inc. ("New Ametek"), which, at the
time of the Spin-Off, will own all of AMETEK's businesses other than the Water
Filtration Business. Second, the Water Filtration Business will be acquired by
Culligan in a stock-for-stock merger (the "Merger") making AMETEK (which then
will be comprised solely of the Water Filtration Business) a subsidiary of
Culligan. Following the Merger, New Ametek will be renamed "AMETEK, Inc." The
Spin-Off and the Merger are intended to be tax-free.
   
  In the Spin-Off, you will receive one share of New Ametek common stock for
each share of AMETEK common stock that you own. In the Merger, you will
receive, subject to adjustment, approximately .11 of a share of Culligan
common stock for each share of AMETEK common stock that you own. This is
equivalent to $    per share of AMETEK common stock based on the market price
of $      for Culligan on June   , 1997.     
 
  The Spin-Off and the Merger must be approved by the stockholders of AMETEK.
The Spin-Off and the Merger are described in detail in the attached Joint
Proxy Statement/Prospectus, the forepart of which includes a summary of the
terms of the Spin-Off and the Merger and certain other information relating to
the proposed transaction. Also, Appendix E to the attached Joint Proxy
Statement/Prospectus is an information statement for New Ametek's common stock
that further describes the business and management of New Ametek. We hope to
complete the transaction in July 1997.
 
  After careful consideration, your Board of Directors has unanimously
determined that the Spin-Off and the Merger are in the best interests of
AMETEK and its stockholders, and unanimously recommends that you vote FOR the
approval of the Spin-Off and the Merger and the transactions contemplated in
connection therewith.
   
  At the Special Meeting you will also be asked to elect eight directors to
the AMETEK Board of Directors, to appoint independent auditors and to transact
such other business as may properly come before the Special Meeting.
Stockholders are entitled to vote all shares of AMETEK common stock owned by
them on June 25, 1997, the record date.     
 
  We urge you to consider carefully these important matters which are
described in the attached Joint Proxy Statement/Prospectus. In order to ensure
that your vote is represented at the meeting, please indicate your choice on
the proxy form, date and sign it, and return it in the enclosed envelope.
Please mark and return the proxy even if you plan to attend the meeting in
person. If you have questions, please contact our Investor Relations
Department at (610) 647-2121.
 
                                          Yours truly,
 
                                          AMETEK, INC.

                                  ----------
   
  This Joint Proxy Statement/Prospectus is furnished in connection with the
solicitation of proxies by the Board of Directors (the "AMETEK Board") of
AMETEK, Inc., a Delaware corporation ("AMETEK"), for use at the Special Meeting
in lieu of the Annual Meeting of Stockholders of AMETEK (including any
adjournments or postponements thereof, the "AMETEK Special Meeting"), to be
held on July 23, 1997 at the Desmond Great Valley Hotel and Conference Center,
One Liberty Boulevard, Malvern, Pennsylvania 19355 at 2:00 p.m. local time. At
the AMETEK Special Meeting, the holders of AMETEK common stock, par value $.01
per share ("AMETEK Common Stock") will, among other things, consider and vote
upon a proposal to approve and adopt the Amended and Restated Agreement and
Plan of Merger and Reorganization, dated as of February 5, 1997 (the "Merger
Agreement"), by and among Culligan Water Technologies, Inc., a Delaware
corporation ("Culligan"), Culligan Water Company, Inc., a Delaware corporation
and a wholly owned subsidiary of Culligan ("Culligan Merger Sub"), AMETEK and
Ametek Aerospace Products, Inc., a Delaware corporation and wholly owned
subsidiary of AMETEK ("New Ametek"), the Amended and Restated Contribution and
Distribution Agreement, dated as of February 5, 1997 (the "Distribution
Agreement"), between AMETEK and New Ametek and the transactions contemplated by
the Merger Agreement and the Distribution Agreement, pursuant to which (a)
AMETEK will transfer or cause to be transferred to New Ametek all of its assets
other than those which are part of the Water Filtration Business (as defined
below), and New Ametek will assume all of AMETEK's liabilities, except for
certain liabilities relating to the Water Filtration Business and certain
indebtedness of AMETEK (collectively, the "Contributions") and, following the
Contributions, AMETEK will distribute to its stockholders on a share for share
basis (the "Spin-Off") all of the outstanding shares of New Ametek ("New Ametek
Common Stock"), and (b) at the effective time of the Merger (the "Effective
Time") on the day following the Spin-Off, Culligan Merger Sub will be merged
with and into AMETEK (which then will be comprised solely of the Water
Filtration Business) (the "Merger"). The Water Filtration Business of AMETEK
consists of the Plymouth Products Division, and the following three foreign
subsidiaries: Ametek Filters, Limited, APIC International S.A. and AFIMO S.A.M.
(collectively, the "Water Filtration Business"). The Spin-Off and the Merger
are intended to be tax-free.     
   
  In the Merger, each share of AMETEK Common Stock will be converted into the
right to receive common stock, par value $.01 per share, of Culligan ("Culligan
Common Stock"). Assuming that 32,903,451 shares of AMETEK Common Stock are
outstanding at the time of the Merger (the number of shares of AMETEK Common
Stock outstanding on June 13, 1997), each share of AMETEK Common Stock will be
converted into approximately .11 of a share of Culligan Common Stock, except
that each holder of AMETEK Common Stock will receive, without interest, cash in
lieu of any fractional share of Culligan Common Stock that such stockholder
would be entitled to receive after aggregating all shares such stockholder is
entitled to receive in the Merger.     
 
  This Joint Proxy Statement/Prospectus also constitutes the prospectus of
Culligan that is part of a Registration Statement on Form S-4 (the "Culligan
Registration Statement") filed with the Securities and Exchange Commission (the
"Commission") with respect to the issuance of 3,466,667 shares of Culligan
Common Stock pursuant to the Merger Agreement.

DISCUSSION OF CERTAIN MATTERS WITH RESPECT TO THE SPIN-OFF, THE MERGER AND AN
INVESTMENT IN CULLIGAN COMMON STOCK UPON CONSUMMATION OF THE MERGER. SEE "RISK
FACTORS" ON PAGE 9 OF THE NEW AMETEK INFORMATION STATEMENT WHICH IS INCLUDED AS
APPENDIX E FOR CERTAIN MATTERS RELEVANT TO THE OWNERSHIP OF NEW AMETEK COMMON
STOCK.     
   
  This Joint Proxy Statement/Prospectus and the accompanying form of proxy are
first being mailed to stockholders of AMETEK on or about June   , 1997.     
 
 NEITHER THIS TRANSACTION NOR  THE SECURITIES TO BE  ISSUED IN CONNECTION  WITH
  THE MERGER HAVE BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND  EXCHANGE
   COMMISSION OR ANY STATE SECURITIES  COMMISSION NOR HAS THE SECURITIES  AND
    EXCHANGE COMMISSION OR ANY STATE  SECURITIES COMMISSION PASSED UPON  THE
     ACCURACY OR  ADEQUACY OF  THIS JOINT  PROXY STATEMENT/PROSPECTUS.  ANY
      REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.
 
                                  ----------
       
    The date of this Joint Proxy Statement/Prospectus is June   , 1997.     
<PAGE>
 
(Continued from page one)
  Based on the number of shares of Culligan Common Stock and AMETEK Common
Stock outstanding on the date hereof, upon consummation of the Merger,
Culligan stockholders at the time of the Merger will continue to hold
approximately 86% of the outstanding Culligan Common Stock and AMETEK
stockholders will hold approximately 14% of the outstanding Culligan Common
Stock.
 
  As a result of the Spin-Off and the Merger, AMETEK will become a wholly
owned subsidiary of Culligan and will be renamed "Culligan Water Company,
Inc." ("Culligan Water Company"), and New Ametek will be renamed "AMETEK,
Inc.," subject to and as more fully described in the Merger Agreement and the
Distribution Agreement, which are attached, respectively, as Appendices A and
B to this Joint Proxy Statement/Prospectus.
 
  Because the Exchange Ratio (as defined herein) is based on a fixed price of
$37.50 for Culligan Common Stock and the market price for Culligan Common
Stock fluctuates, the value of the Culligan Common Stock that holders of
AMETEK Common Stock will receive in the Merger increases as the market price
of Culligan Common Stock increases and decreases as the market price of
Culligan Common Stock decreases. In addition, because additional shares of
AMETEK Common Stock may be issued prior to the Effective Time, the value of
the consideration per share received by holders of AMETEK Common Stock in the
Merger may decrease. See "THE MERGER AGREEMENT--Conversion of AMETEK Common
Stock."
   
  Culligan Common Stock is listed for trading on the New York Stock Exchange
("NYSE"). On February 4, 1997, the last trading day prior to the execution of
the Merger Agreement, the closing sale price per share of Culligan Common
Stock, as reported on the NYSE Composite Tape, was $36.375. On June   , 1997,
the last trading day prior to the first mailing of this Joint Proxy
Statement/Prospectus, the closing sale price per share of Culligan Common
Stock, as reported on the NYSE Composite Tape, was $  .     
   
  There is currently no trading market for New Ametek Common Stock; however,
it is expected that a "when-issued" trading market will develop for the New
Ametek Common Stock prior to the Merger. New Ametek has applied to list the
New Ametek Common Stock on the NYSE and on the Pacific Exchange, Inc. (the
"PCX"). As a result of the transaction, holders of AMETEK Common Stock
immediately prior to the Spin-Off will receive shares of New Ametek Common
Stock in the Spin-Off and, upon surrendering their AMETEK Common Stock
certificates in accordance with the Merger Agreement, will receive shares of
Culligan Common Stock in the Merger.     
 
  APPENDIX E TO THIS JOINT PROXY STATEMENT/PROSPECTUS IS FURNISHED TO HOLDERS
OF AMETEK COMMON STOCK AS AN INFORMATION STATEMENT (THE "NEW AMETEK

CULLIGAN
 
  Culligan is one of the world's leading manufacturers and distributors of
water purification and treatment products and services for household and
consumer, and commercial and industrial applications. Products and services
offered by Culligan range from those designed to solve residential water
problems, such as filters for tap water and household water softeners, to
highly sophisticated equipment and services, such as ultrafiltration and
microfiltration products, desalination systems and portable deionization
services ("PDS"), designed for complex commercial and industrial applications.
In addition, Culligan's licensed bottled water sales now rank fourth in the
five-gallon bottled water market in the United States. In fiscal 1997, Culligan
entered the consumer market selling filtration products directly to retailers.
 
  Culligan has been an active participant in the water purification and
treatment industry since 1936, and its Culligan (R), Everpure (R) and
Bruner (R) brands are among the most recognized in the industry. Culligan's
products are sold and serviced in over 90 countries through a worldwide network
of over 1,400 sales and service centers. Supporting this distribution network,
Culligan maintains manufacturing facilities in the United States, Italy, Spain
and Canada. During the last 15 years, Culligan's residential water treatment
systems have been installed in over 3 million households in the United States,
representing the largest installed base in the country. In addition, over 1.5
million of Culligan's commercial, industrial, municipal and desalination
systems have been installed worldwide. Culligan's customer base includes such
well known names as McDonald's (R), Coca-Cola (R), Pepsi-Cola (R),
Starbucks (R), 7-Eleven (R), Navistar, Owens-Corning, Eli Lilly, Carnival
Cruise Lines, Ingersoll-Rand and Union Carbide.
 
  With net sales of $371 million for the fiscal year ended January 31, 1997,
Culligan is one of the leaders in the highly fragmented water purification and
treatment industry. Culligan and its dealers provide a wide range of services
to support its products and offer a full line of accessories and replacement
parts. Approximately 46% of Culligan's revenues in fiscal 1997 were derived
from sources believed to be recurring in nature, such as servicing installed
equipment, sales of replacement parts, filters and other consumables, equipment
rental and royalties. In fiscal 1997, approximately 36% of Culligan's revenues
were from export and international sales. Culligan conducts its activities in
two principal areas: household and consumer and commercial and industrial.
 
  Culligan is a holding company and conducts all of its operations through its
subsidiaries. Culligan Common Stock is listed on the NYSE. Culligan's executive
offices are located at One Culligan Parkway, Northbrook, Illinois 60062-6209

                          THE SPIN-OFF AND THE MERGER
 
BACKGROUND OF THE SPIN-OFF AND THE MERGER
 
  Culligan contacted AMETEK in April and August 1996 regarding a possible
acquisition of its Water Filtration Business. The parties entered into a
confidentiality agreement in October 1996 with respect to the Water Filtration
Business. Culligan then proceeded to evaluate certain financial information it
received from AMETEK and to refine its valuation of the Water Filtration
Business. The parties also discussed potential structures for the proposed
transaction. By early December 1996, the parties had agreed to a structure
intended to be tax-free to AMETEK and its stockholders, which would involve a
spin-off by AMETEK of all of its businesses other than the Water Filtration
Business, and Culligan thereafter merging a subsidiary into AMETEK which then
would hold only the Water Filtration Business. This structure was determined to
be the only viable means of effecting the proposed transaction within the
proposed range of values. Culligan and AMETEK had also narrowed the gap between
their respective valuations of the Water Filtration Business, although a
definitive agreement on valuation and price had not been reached. From late
December 1996 through January 1997, representatives of Culligan and AMETEK
endeavored to negotiate definitive transaction documentation and resolve other
issues relating to the proposed transaction. On February 4, 1997, Culligan and
AMETEK concluded their negotiations regarding valuation and price and the
Boards of Culligan and AMETEK approved the proposed transaction. On February 5,
1997, Culligan and AMETEK executed the Merger Agreement, and AMETEK and New
Ametek executed the Distribution Agreement. On May 9, 1997, the Merger
Agreement and the Distribution Agreement were amended and restated. See
"BACKGROUND OF THE SPIN-OFF AND THE MERGER."
 
RECOMMENDATION OF THE AMETEK BOARD
 
  The AMETEK Board has unanimously approved the Merger Agreement and the
Distribution Agreement and determined that the Merger and the Spin-Off, taken
as a whole, are fair to and in the best interests of AMETEK and its
stockholders. THE AMETEK BOARD UNANIMOUSLY RECOMMENDS THAT HOLDERS OF AMETEK
COMMON STOCK VOTE FOR THE APPROVAL AND ADOPTION OF THE MERGER AGREEMENT, THE
DISTRIBUTION AGREEMENT, THE MERGER AND THE SPIN-OFF. For a discussion of
factors considered by the AMETEK Board in reaching its decision, see "REASONS
FOR THE TRANSACTION; RECOMMENDATION OF THE AMETEK BOARD." In considering the
recommendation of the AMETEK Board with respect to the Merger, holders of
AMETEK Common Stock should be aware that certain officers and directors may
have direct or indirect interests in recommending the Merger, apart from their
interests as holders of AMETEK Common Stock, which are not identical to those
of unaffiliated stockholders of AMETEK. See "THE MERGER AGREEMENT--Interest of
Certain Persons in the Transaction."

  The Board of Directors of Culligan (the "Culligan Board") has also
unanimously approved the Merger Agreement.
 
OVERVIEW OF THE SPIN-OFF AND THE MERGER
 
  As a result of the Spin-Off, AMETEK will separate all of its other businesses
from the Water Filtration Business and consist solely of the Water Filtration
Business at the time of the Merger. The Merger Agreement provides that,
following the Spin-Off, Culligan Merger Sub will be merged with and into
AMETEK, with AMETEK (then renamed "Culligan Water Company, Inc.") surviving the
Merger as a wholly owned subsidiary of Culligan. As a result of the Spin-Off
and the Merger, holders of AMETEK Common Stock will no longer own shares of
AMETEK Common Stock but will receive shares of New Ametek Common Stock and
Culligan Common Stock. Culligan will issue 3,466,667 shares in the Merger.
Based on the number of shares of Culligan Common Stock and AMETEK Common Stock
outstanding on the date hereof, upon consummation of the Merger, Culligan
stockholders at the time of the Merger will continue to hold approximately 86%
of the outstanding Culligan Common Stock and AMETEK stockholders will hold
approximately 14% of the outstanding Culligan Common Stock.
 
TERMS OF THE MERGER
 
  Conversion of AMETEK Common Stock in the Merger. The Merger Agreement
provides that each share of AMETEK Common Stock will be converted into the
right to receive a fraction of a share of Culligan Common Stock based on a
formula that specifies that each share of AMETEK Common Stock outstanding on
the Spin-Off Record Date will be converted into a number of shares of Culligan
Common Stock equal to (i) the Net Equity Value (as defined below), divided by
(ii) $37.50, divided by (iii) the number of shares of AMETEK Common Stock
outstanding at the Effective Time (the "Exchange Ratio"). The Net Equity Value
is an amount equal to (A) $155,000,000 minus (B) $25,000,000, the amount of the
bank debt to be retained by AMETEK (the "Retained Debt"). Based on the
foregoing calculation, the Net Equity Value will be $130,000,000. Under this
formula, the Exchange Ratio varies with the number of shares of AMETEK Common
Stock outstanding at the time of the Merger.
 
  All shares of AMETEK Common Stock when converted pursuant to the Merger
Agreement will no longer remain outstanding and will automatically be canceled
and retired, and each holder of a certificate representing any such shares will
cease to have any rights with respect thereto, except the right to receive the
shares of Culligan Common Stock and cash in lieu of any fractional share of
Culligan Common Stock to be issued or paid upon the surrender of such
certificate in accordance with the Merger Agreement.
 
  Fractional Shares. The Merger Agreement provides that each holder of AMETEK
Common Stock will receive, without interest, cash in lieu of any fractional
share of Culligan Common Stock that such stockholder would be entitled to
receive after aggregating all shares such stockholder is entitled to receive in
the Merger.
   
  Effective Time of the Merger. The Merger will become effective upon the
filing of a Certificate of Merger (the "Certificate of Merger") with the
Secretary of State of the State of Delaware or as otherwise provided in the
Certificate of Merger. Assuming that the requisite stockholder approval of the
Merger is obtained, it is anticipated that the Effective Time of the Merger
will occur on the business day following the day on which the Spin-Off is
effected. However, if all other conditions to the Merger have not been
satisfied prior to the AMETEK Special Meeting, it is expected that the Merger
will occur within two business days after such conditions have been satisfied
or waived.     
 
  Audited Closing Balance Sheet. The Merger Agreement provides that no later
than 45 days after the Closing Date, New Ametek will deliver to Culligan an
audited consolidated balance sheet for the Water Filtration Business as of the
Closing Date after giving effect to the Spin-Off, but not the Merger (the
"Audited Closing
 
                                       11
<PAGE>
 
Balance Sheet"). Together with the delivery of the Audited Closing Balance
Sheet, New Ametek will deliver an adjusted balance sheet of the Water
Filtration Business as of the Closing Date (the "Adjusted Closing Balance
Sheet") which will be the Audited Closing Balance Sheet adjusted as described
in "THE MERGER AGREEMENT--Certain Pre- and Post-Merger Transactions--Audited
Closing Balance Sheet." To the extent the Adjusted Net Worth of the Water
Filtration Business as calculated from the Adjusted Closing Balance Sheet is
less than $31,745,000, then New Ametek will pay to the Surviving Corporation
the amount of such shortfall. To the extent that the Adjusted Net Worth of the
Water Filtration Business as calculated from the Adjusted Audited Closing
Balance Sheet is more than $31,745,000, then the Surviving Corporation will pay
New Ametek in cash the amount of such excess up to a maximum amount of
$2,000,000.
 
  Government and Regulatory Approvals. Consummation of the Merger was
conditioned upon the expiration or termination of the waiting period under the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR
Act"). On March 14, 1997, Culligan and AMETEK each filed notification reports
under the HSR Act with the Federal Trade Commission (the "FTC") and the
Antitrust Division of the Department of Justice (the "DOJ"). Early termination
of the waiting period was granted on March 24, 1997.
   
  Receipt of Private Letter Ruling. The Contributions, the Spin-Off and the
Merger were conditioned upon the issuance by the Internal Revenue Service (the
"IRS") of a private letter ruling (the "Private Letter Ruling") reasonably
satisfactory in form and substance to AMETEK and Culligan substantially to the
effect that, on the basis of the facts, representations and assumptions
existing at the Effective Time: (i) the Contributions followed by the Spin-Off
qualify as a tax-free reorganization pursuant to Section 368(a)(1)(D) of the
Internal Revenue Code of 1986, as amended (the "Code"); (ii) the Spin-Off
qualifies as a tax-free distribution pursuant to Section 355(a) of the Code;
and (iii) the Merger qualifies as a tax-free reorganization pursuant to Section
368 (a)(1)(B) of the Code. The Private Letter Ruling was issued by the IRS on
June 16, 1997. If the IRS revokes the Private Letter Ruling, this condition
will nevertheless be satisfied if, on or prior to the Closing Date, AMETEK and
Culligan receive the Tax Opinions to the same effect as the Private Letter
Ruling. See "CERTAIN FEDERAL INCOME TAX CONSEQUENCES."     
 
  Other Conditions to Merger. The obligations of Culligan and AMETEK to
consummate the Merger are also subject to approval of the Merger Agreement by
holders of AMETEK Common Stock, the Average Culligan Share Price being greater
than $31.00 on the Closing Date, receipt of the Private Letter Ruling and/or
the Tax Opinions and the satisfaction of certain customary and other
conditions, including, without limitation, that the Spin-Off has become
effective and that shares of Culligan Common Stock to be issued in the Merger
have been authorized for listing on the NYSE subject to notice of issuance. See
"THE MERGER AGREEMENT--Conditions."
 
CONSENT SOLICITATION
   
  AMETEK announced on June 2, 1997 that it had obtained the consent of a
majority of the holders of AMETEK's outstanding 9 3/4% Senior Notes Due 2004
(the "Notes") to an amendment to the Indenture, dated as of March 15, 1994,
between AMETEK and CoreStates Bank, N.A., as Trustee, as amended and
supplemented (the "Indenture"), pursuant to which the Notes were issued,
intended to clarify that the Spin-Off and the Merger do not conflict with any
covenant contained in the Indenture. New Ametek will assume the Notes in
connection with the Contributions and the Spin-Off. AMETEK paid holders who
timely consented to the amendment a consent fee of $3.75 per $1,000 in
principal amount of the Notes.     
 
TERMINATION OR AMENDMENT OF THE MERGER AGREEMENT
 
  Termination. The Merger Agreement may be terminated under certain
circumstances, including (a) by the mutual consent of Culligan and AMETEK, (b)
by either Culligan or AMETEK at any time prior to the
 
                                       12
<PAGE>
 
consummation of the Merger (i) upon a material breach of a representation,
warranty or covenant on the part of the other party, or if there is a material
failure by the other party to comply with its obligations under the Merger
Agreement or the Distribution Agreement, as the case may be, (ii) if the Merger
has not been consummated before October 31, 1997, or (iii) if the Merger
Agreement, the Distribution Agreement, the Merger and the Spin-Off fail to
receive the requisite vote for approval and adoption by the holders of AMETEK
Common Stock at the AMETEK Special Meeting; (c) by Culligan, if the AMETEK
Board withdraws, modifies or changes its recommendation of the Merger Agreement
or the Merger in a manner adverse to Culligan; and (d) by either Culligan or
AMETEK if any change in Federal income tax law or regulation applicable to the
Contributions, the Spin-Off or the Merger disqualifies any one of such
transactions or combination thereof from tax-free treatment.
 
  Termination Fee. Under certain circumstances, AMETEK is required to pay
Culligan upon termination of the Merger Agreement a fee of $5,000,000, in
addition to all of Culligan's expenses in connection with the Merger. See "THE
MERGER AGREEMENT--Fees and Expenses."
   
  Amendment; Waiver. The Merger Agreement may be amended or modified and any
condition specified therein may be waived by the mutual consent of Culligan and
AMETEK; provided that, after any stockholder approval, no amendment will be
made if applicable law requires further approval by the stockholders.     
 
  No Solicitation. The Merger Agreement also contains certain non-solicitation
provisions relating to AMETEK. See "THE MERGER AGREEMENT--No Solicitation."
 
INTEREST OF CERTAIN PERSONS IN THE TRANSACTION
 
  In considering the recommendation of the AMETEK Board, holders of AMETEK
Common Stock should be aware that certain members of management of AMETEK and
the AMETEK Board may have certain interests in the Spin-Off and the Merger that
are in addition to the interests of stockholders generally. See "THE MERGER
AGREEMENT--Interest of Certain Persons in the Transaction."
 
ACCOUNTING TREATMENT
 
  The Merger will be accounted for by Culligan using the purchase method of
accounting under generally accepted accounting principles. See "THE MERGER
AGREEMENT--Accounting Treatment." New Ametek will account for the Merger as a
spin-off of the Water Filtration Business, which will be reflected as a
discontinued operation in New Ametek's consolidated financial statements.
 
THE SPIN-OFF
 
  Subject to stockholder approval of the Spin-Off and the Merger, the Spin-Off
will be effected on the business day prior to the Merger (the "Spin-Off Date").
The Contributions followed by the Spin-Off will separate all of AMETEK's other
businesses from its Water Filtration Business, and enable Culligan to acquire
only the Water Filtration Business in the Merger; the Spin-Off will leave
AMETEK's remaining businesses as a separate publicly held company (New Ametek),
owned by the existing holders of AMETEK Common Stock. Prior to the Spin-Off,
AMETEK will transfer all of its assets and liabilities (other than those
comprising the Water Filtration Business and the Retained Debt) to New Ametek.
The directors and officers of AMETEK will be the directors and officers of New
Ametek at the time of the Spin-Off. See "THE SPIN-OFF--Terms of the
Distribution Agreement--The Contributions" and the Distribution Agreement
included as Appendix B to this Joint Proxy Statement/Prospectus for additional
information regarding the transfer of assets to, and assumption of liabilities
by, New Ametek.
 
                                       13
<PAGE>
 
 
  Pursuant to the Spin-Off, each holder of AMETEK Common Stock will receive one
share of New Ametek Common Stock for each share of AMETEK Common Stock held by
such stockholder. The Spin-Off will be effected by the distribution to each
holder of record of AMETEK Common Stock, of certificates representing New
Ametek Common Stock. See "THE SPIN-OFF--Terms of the Distribution Agreement--
The Spin-Off." The record date shall be set by the AMETEK Board, currently
anticipated to follow promptly the satisfaction or waiver of the conditions to
the Merger (the "Spin-Off Record Date"). As a result of the Spin-Off, the
holders of AMETEK Common Stock will become the stockholders of New Ametek.
 
NO APPRAISAL RIGHTS
 
  Holders of AMETEK Common Stock will not have the right to elect to have the
fair value of their shares of AMETEK Common Stock judicially appraised and paid
to them in cash in connection with the Spin-Off or the Merger.
 
                          OPINION OF FINANCIAL ADVISOR
 
  Goldman, Sachs & Co. ("Goldman Sachs") has delivered its written opinion to
the AMETEK Board that, as of February 5, 1997, the Exchange Ratio pursuant to
the Merger Agreement was fair to the holders of AMETEK Common Stock.
 
  The full text of the written opinion of Goldman Sachs, which sets forth
assumptions made, matters considered and limitations on the review undertaken
in connection with the opinion, is attached hereto as Appendix C and is
incorporated herein by reference. Holders of AMETEK Common Stock are urged to,
and should, read such opinion in its entirety. See "OPINION OF THE FINANCIAL
ADVISOR."
 
                              RECENT DEVELOPMENTS
   
  On April 17, 1997, AMETEK announced it had signed a definitive agreement to
acquire the Test & Measurement Products business of Technitrol, Inc., for $34
million in cash. The acquisition was completed on June 4, 1997. The acquired
business had annual sales of approximately $30 million and manufactures a
comprehensive line of measurement and testing devices, including gauges,
electronic instruments and test stands, and analytical software and support
services.     
 
                        STOCKHOLDERS' COMPARATIVE RIGHTS
   
  The rights of AMETEK's stockholders are currently governed by AMETEK's
Certificate of Incorporation, as amended (the "AMETEK Certificate") and By-Laws
(the "AMETEK By-Laws") and Delaware corporate law. At the Effective Time,
AMETEK's stockholders will become stockholders of Culligan and their rights as
stockholders will be governed by Culligan's Amended and Restated Certificate of
Incorporation (the "Culligan Certificate") and Amended and Restated By-Laws
(the "Culligan By-Laws") and Delaware corporate law. See "COMPARISON OF RIGHTS
OF STOCKHOLDERS." As a result of the Spin-Off, holders of AMETEK Common Stock
will also become stockholders of New Ametek. See "DESCRIPTION OF NEW AMETEK
CAPITAL STOCK" in the New Ametek Information Statement, which is included as
Appendix E to this Joint Proxy Statement/Prospectus for a description of the
rights of holders of New Ametek Common Stock.

(a) In September 1995, Culligan's former parent distributed to its stockholders
    all of the then outstanding Culligan Common Stock (the "Culligan Spin-
    Off"). From the Culligan Spin-Off in September 1995 until December 15, 1995
    (the date on which trading in Culligan Common Stock commenced on the NYSE),
    there was no established public trading market for Culligan Common Stock.
    During such period, approximately 84% of Culligan Common Stock was held by
    four beneficial owners and Culligan Common Stock was not listed on any
    securities exchange. During that period, Culligan Common Stock was traded
    in interdealer and over-the-counter bulletin board transactions. The bid
    quotations for Culligan Common Stock from the Culligan Spin-Off through
    December 14, 1995 ranged from a high of $25 1/2 per share on December 12,
    1995 to a low of $14 per share on September 28, 1995. Although the
    quotations for the period prior to December 15, 1995 have been obtained
    from sources believed to be reliable, no assurances can be given with
    respect to the accuracy of such quotations or as to whether other bid
    prices higher or lower than those set forth above may have been quoted. In
    addition, such quotations reflect interdealer prices, which may not include
    retail mark-up, mark-down or commission and may not necessarily represent
    actual transactions.
   
  There is currently no public trading market for the New Ametek Common Stock.
Application has been made to list the New Ametek Common Stock on the NYSE and
PCX. It is expected that a "when-issued" trading market will develop for the
New Ametek Common Stock; however, there can be no assurance that an active
trading market will develop or, if a trading market develops, that such a
market will be maintained. There can be no assurance as to the prices at which
New Ametek Common Stock will trade after the Spin-Off.     
   
  On February 4, 1997, the last trading day prior to the public announcement of
the Merger and on June   , 1997, the last trading day prior to the first
mailing of this Joint Proxy Statement/Prospectus, the closing sales price per
share of Culligan Common Stock as reported on the NYSE was $36.375 and $      ,
respectively. On June 13, 1997, there were 95 holders of record of Culligan
Common Stock and there were 21,391,201 shares of Culligan Common Stock
outstanding.

IMPACT OF NONRECURRING ITEMS
   
  Included in Culligan's statements of operations subsequent to June 30,1993,
are amortization and depreciation related to adjustments of assets and
liabilities to fair value in connection with the adoption of the American
Institute of Certified Public Accountants Statement of Position 90-7 entitled
"Financial Reporting by Entities in Reorganization Under the Bankruptcy Code"
("SOP 90-7"). The most significant adjustment relates to reorganization value
in excess of identifiable assets which was amortized over a three-year period
which ended in June 1996. In addition, the statement of operations for the year
ended January 31, 1997 and the three months ended April 30, 1997 include
certain items which are not expected to recur, including a gain on an insurance
settlement associated with a fire at Culligan's Belgian facility in July 1993
and a gain on the disposition on an investment in an affiliate. Due to the
significance of these items, and considering that they are either of a short
duration or nonrecurring, management believes that it is useful to isolate
their impact on the statement of operations. The after tax impact on net income
and the impact on net income per share are shown below. This information does
not represent and should not be considered an alternative to net income, any
other measure of performance as determined by generally accepted accounting
principles or as an indicator of operating performance.

(a) In June 1993, Astrum International Corp. ("Astrum"), the predecessor of the
    Company's former parent Samsonite Corporation ("Samsonite"), completed a
    financial restructuring pursuant to a plan of reorganization under Chapter
    11 of the United States Bankruptcy Code (the "Plan"). Effective June 30,
    1993 and pursuant to SOP 90-7, Astrum and all its subsidiaries, including
    Culligan, were required to adjust their assets and liabilities to their
    fair ("Fresh Start") values. Due to the effect of SOP 90-7, amortization of
    intangible assets and interest expense (see notes (d) and (g) below) for
    the periods before and after June 30, 1993 are not comparable. The
    information for the predecessor company reflects activity occurring through
    June 30, 1993, prior to the effective date of the Plan.
(b) Administrative expenses allocated from Samsonite represent certain
    accounting and management services performed for the benefit of Culligan
    primarily related to Astrum's reorganization and the distribution of
    Culligan Common Stock to stockholders of Samsonite (the "Culligan Spin-
    Off"). In prior years, these services were not provided, and are not
    anticipated to recur on an on-going basis.
(c) Culligan implemented a plan to consolidate the production facilities and
    administrative functions of certain operations in Europe. The severance,
    other personnel related costs and facility shut-down expenses related to
    the restructuring resulted in charges in fiscal 1994 and fiscal 1995 of
    $2.1 million and $5.9 million, respectively.
(d) Amortization of intangible assets consists of the following:

  Property and equipment revalued in connection with the adoption of SOP 90-7
  are being depreciated over their respective estimated useful lives,
  primarily ranging from two to six years.
 
(f) Other income, net for fiscal 1997 includes a gain of approximately $2
    million on an insurance settlement associated with a fire at Culligan's
    Belgian facility in July 1993.
 
(g) Interest expense for periods subsequent to June 30, 1993 includes interest
    on the $150 million note payable to Samsonite issued in connection with
    Astrum's reorganization. A principal payment of $20 million to Samsonite
    and a $30 million contribution by Samsonite to equity capital of Culligan
    on December 1, 1994 and January 31, 1995, respectively, reduced the
    outstanding principal during fiscal 1995. During July 1995, borrowings
    under a $150 million credit facility entered into by Culligan in July 1995
    (the "Culligan Credit Facility") were used to repay in full the outstanding
    balance of the note payable to Samsonite (the "Refinancing").
   
(h) On March 15, 1997, Culligan disposed of its investment in Anvil Holdings,
    Inc. for total cash proceeds of approximately $51 million. The transaction,
    which included repayment of outstanding accrued interest receivable and
    dividends resulted in a pre-tax gain of approximately $31 million.     
   
(i) EBITDA is defined as income before interest and taxes, restructuring
    expense and administrative expenses allocated from Samsonite plus
    depreciation and amortization. Culligan believes that EBITDA provides
    useful information regarding liquidity. The computation of EBITDA as
    presented may not be comparable to computations presented by other
    companies. This information does not represent and should not be considered
    an alternative to net income, any other measure of performance as
    determined by generally accepted accounting principles or as an indicator
    of operating performance.     
   
(j) Includes the effects of SOP 90-7 "Fresh Start" reporting recorded at June
    30, 1993, net of depreciation and amortization. Pursuant to SOP 90-7, the
    net book value of property and equipment was increased by $28 million,
    intangible and other assets were increased by $110 million, and a deferred
    tax liability of $35 million was recorded. In addition, in June 1993,
    Culligan issued a subordinated note payable to Samsonite in the amount of
    $150 million.     
   
(k) At January 31, 1994, cash decreased $91 million primarily as a result of
    payments of dividends and intercompany payables in connection with Astrum's
    reorganization.     
          
(l) During fiscal 1994, Culligan paid dividends to Samsonite of $76 million. In
    addition, the effects of "Fresh Start" reporting recorded at June 30, 1993,
    net of the impact of issuing the $150 million note payable to Samsonite,
    reduced equity capital by approximately $47 million.     
   
(m) During fiscal 1995, a principal payment of $20 million to Samsonite and a
    $30 million contribution by Samsonite to equity capital of Culligan were
    made on December 1, 1994 and January 31, 1995, respectively, related to the
    note payable to Samsonite.     
   
(n) During fiscal 1996, Culligan completed the sale of 4,025,000 shares of
    common stock. Net proceeds included in equity capital at January 31, 1996
    are approximately $85 million. Culligan used such proceeds to repay
    borrowings under the Culligan Credit Facility. Also during fiscal 1996,
    prior to the Culligan Spin-Off, Samsonite contributed approximately $5
    million to equity capital of Culligan.     
   
(o) During fiscal 1997, Culligan issued additional shares of common stock upon
    the exercise of overallotment options granted to underwriters in connection
    with a secondary public offering of shares of Culligan's common stock. The
    net proceeds included in equity capital at January 31, 1997 are
    approximately $32 million which includes proceeds from the exercise of
    stock options by one of the selling stockholders in the offering. In
    addition, as a result of the exercise of stock options, Culligan recognized
    an income tax benefit of approximately $7.5 million which it recorded as
    additional paid-in-capital during fiscal 1997.

- --------
(a) Amounts in 1993 include pre-tax charges totaling $54.9 million ($33.5
    million after tax, or $.77 per share) for restructuring and other unusual
    items.
 
(b) Special items in 1995 include a $10.4 million ($.31 per share) gain from
    the sale of a discontinued operation and a $2.7 million ($.08 per share)
    after-tax loss related to debt agreements. Amounts in 1994 include an $11.8
    million ($.32 per share) after-tax loss on the early extinguishments of
    debt and an after-tax gain of $3.8 million ($.11 per share) from the effect
    of a change in accounting for certain marketable securities.
   
(c) EBITDA represents income from continuing operations before interest, taxes,
    depreciation and amortization, amortization of deferred financing costs,
    and nonrecurring items. It should not be considered, however, an
    alternative to operating income as an indicator of AMETEK's operating
    performance, or as an alternative to cash flow as a measure of AMETEK's
    overall liquidity as presented in AMETEK's financial statements. The EBITDA
    measure presented may not be comparable to other similar titled measures
    presented by other companies.     
 
(d) For purposes of calculating the ratio of earnings to fixed charges,
    earnings represents income from continuing operations before income taxes
    and fixed charges. Fixed charges consist of interest expense, amortization
    of deferred financing costs and the estimated component of operating lease
    expenses representing interest (assumed to be one-third). Earnings from
    continuing operations in 1993 were insufficient to cover fixed charges by
    approximately $13.5 million.

           NEW AMETEK UNAUDITED PRO FORMA FINANCIAL INFORMATION     
   
  The unaudited pro forma condensed consolidated statement of income of New
Ametek for the three month period ended March 31, 1997, and for the year ended
December 31, 1996, and the unaudited pro forma condensed consolidated balance
sheet as of March 31, 1997 are derived by eliminating the Water Filtration
Business from the historical cost financial statements of AMETEK and are
presented as if the Spin-Off and the Merger had occurred on January 1, 1996 for
the pro forma statement of income and on March 31, 1997 for the pro forma
balance sheet. In connection with the Spin-Off and the Merger, AMETEK will
transfer to New Ametek all of AMETEK's assets and liabilities, except for those
assets and certain liabilities relating to the Water Filtration Business and
certain indebtedness of AMETEK, and all of the outstanding shares of New Ametek
Common Stock will be distributed on a share for share basis to the holders of
AMETEK Common Stock.     
   
  The unaudited pro forma condensed consolidated financial information is
presented for illustrative purposes only and is not necessarily indicative of
either (i) the financial condition or operating results that would have
occurred for the three month period ended on March 31, 1997 or for the year
ended December 31, 1996 in the case of the pro forma condensed consolidated
statement of income, or on March 31, 1997, in the case of the pro forma
condensed consolidated balance sheet, or (ii) New Ametek's future operating
results or financial position. The pro forma adjustments described in the
accompanying notes to the Unaudited Pro Forma Condensed Consolidated Financial
Statements are based upon estimates and assumptions that management believes
are reasonable.

    NOTES TO AMETEK HISTORICAL AND NEW AMETEK UNAUDITED PRO FORMA CONDENSED
                     CONSOLIDATED FINANCIAL STATEMENTS     
   
(a) The elimination of the Water Filtration Business is based on the assumption
    that the Spin-Off and the Merger, which are subject to AMETEK stockholder
    approval, took place as of January 1, 1996 for the pro forma income
    statement, and as of March 31, 1997 for the pro forma balance sheet. The
    statement of income and the balance sheet of the Water Filtration Business
    were derived from AMETEK's historical cost financial accounts and include
    certain allocations based upon methods considered reasonable by AMETEK's
    management. The financial statements of the Water Filtration Business
    referred to above were prepared in contemplation of the Merger.     
   
(b) To eliminate certain costs and expenses of AMETEK which were associated
    with the removal of the Water Filtration Business, and to reclassify
    certain commissions from other income to cost of sales.     
   
(c) To reflect the elimination of interest expense on debt of $25 million
    assumed to be transferred to Culligan in connection with the Spin-Off and
    the Merger.     
   
(d) To record estimated income taxes on the pro forma adjustments at statutory
    rates.     
   
(e) To record the settlement of intra-company loans and fees due AMETEK by the
    Water Filtration Business.     
   
(f) To reflect estimated fees and other expenses New Ametek expects to incur in
    1997 in connection with the divestiture of the Water Filtration Business,
    and recognize the related income tax benefit on such fees and expenses.
    Such fees and expenses have not been reflected in the pro forma condensed
    consolidated statement of income because they are non-recurring.     
   
(g) To reflect the assumed transfer of $25 million of debt from AMETEK to
    Culligan in connection with the Spin-Off.     
   
(h) To retire the issued treasury shares of AMETEK in accordance with the
    provisions of the Merger Agreement.

EQUIVALENT AMETEK AND CULLIGAN PRO FORMA PER COMMON SHARE DATA
   
  The following table sets forth for AMETEK Common Stock certain per share
historical financial information, and for Culligan and New Ametek, certain per
share pro forma financial information for the three month period ended March
31, 1997 and for the year ended December 31, 1996 as to AMETEK, and for the
three month period ended April 30, 1997 and for the year ended January 31, 1997
as to Culligan. The pro forma Culligan information is derived by multiplying
the Culligan pro forma earnings, dividends, and book value per share by an
assumed Merger consideration per share ratio of .11 shares of Culligan Common
Stock for each share of AMETEK Common Stock. The pro forma New Ametek
information is derived by multiplying the New Ametek pro forma earnings and
book value per share by the distribution ratio of one share of New Ametek
Common Stock for each share of AMETEK Common Stock.

                                 RISK FACTORS
 
  In addition to the other information set forth in this Joint Proxy
Statement/Prospectus, the following factors should be considered by the
holders of AMETEK Common Stock before voting on the proposals herein. This
Joint Proxy Statement/Prospectus contains certain forward-looking statements
within the meaning of Section 27A of the Securities Act, and Section 21E of
the Exchange Act. Such statements are subject to inherent risks and
uncertainties, some of which cannot be predicted or quantified. Actual results
could differ materially from those projected in the forward-looking statements
as a result of certain of the risk factors set forth under "RISK FACTORS" and
elsewhere in this Joint Proxy Statement/Prospectus.
   
RISKS ASSOCIATED WITH THE MERGER     
 
  Expected Benefits of Combined Business May Not Be Achieved. There can be no
assurance that the expected benefits of the Merger related to the combined
businesses as described under "REASONS FOR THE TRANSACTION; RECOMMENDATION OF
THE AMETEK BOARD" will be achieved. The integration of the two water
filtration businesses may present management challenges and there can be no
assurance that such actions needed to meet these challenges will be
successfully accomplished within a specified period of time.
 
  Changes in Value of Merger Consideration Per Share. The stock price of
Culligan Common Stock at the Effective Time may vary from the prices as of the
date of execution of the Merger Agreement, the date hereof, or the date on
which stockholders vote on the Merger due to, among other factors, changes in
the business, operations and prospects of Culligan or AMETEK, market
assessments of the likelihood that the Merger will be consummated and the
timing thereof, and general market and economic conditions. Because the
Exchange Ratio is based on a fixed-price of $37.50 for Culligan Common Stock
and the market price for Culligan Common Stock fluctuates, the value of the
Culligan Common Stock that holders of AMETEK Common Stock will receive in the
Merger increases as the market price of Culligan Common Stock increases and
decreases as the market price of Culligan Common Stock decreases. In addition,
because additional shares of AMETEK Common Stock may be issued prior to the
Effective Time, the value of the consideration per share received by holders
of AMETEK Common Stock in the Merger may decrease. See "THE MERGER AGREEMENT--
Conversion of AMETEK Common Stock."
   
RISKS WHICH CURRENTLY APPLY TO CULLIGAN     
   
  Significant Non-Cash Charges of Culligan; Reported Losses. As a result of
the emergence from bankruptcy of Culligan's former parent (the "Former
Parent") in June 1993, the Former Parent and all its subsidiaries, including
Culligan, were required to adjust their assets and liabilities to reflect
their fair values. The reorganization value in excess of identifiable assets
of Culligan, which was $112 million at the time of the Former Parent's
emergence from bankruptcy, was amortized through charges to the consolidated
statement of operations over a three year period that ended in June 1996.
While these amounts represent non-cash charges, they have had an adverse
effect on reported results of operations in fiscal years 1995, 1996 and 1997.
The losses so reported as a result of the amortization of these charges have
had a similar effect on reported stockholders' equity. See "SUMMARY CONDENSED
HISTORICAL AND PRO FORMA FINANCIAL INFORMATION." The Merger will result in
substantial goodwill (estimated to be approximately $118.6 million) which is
expected to be amortized on a straight line basis over a 40-year period.     
 
  General Business Strategy. Culligan's business strategy includes initiatives
to increase advertising expenditures, expand its distribution network in both
new and existing markets, expand its direct sales force, develop new products,
make strategic acquisitions of businesses, products and technology, introduce
existing products and technologies into its new markets and distribution
channels and introduce new products and services internationally. Culligan's
strategic plan should be considered in light of the risks, expenses and
difficulties frequently encountered in growing a business enterprise. Culligan
expects to incur significant costs in attempting to implement the initiatives
described above. The success in implementing those initiatives will depend on
numerous factors, many of which are beyond Culligan's control, including
economic, competitive and other conditions and uncertainties and no assurance
can be given that Culligan will be successful in implementing its business
strategy. Culligan's growth strategy is expected to require greater capital
for its successful execution than Culligan has previously required. There can
be no assurance that Culligan will grow as desired.
 
 
                                      32
<PAGE>
 
  Acquisition Strategy. Culligan's business strategy depends in part on its
ability to effect acquisitions in the fragmented water purification and
treatment industry. Culligan continually explores acquisition opportunities.
The purchase price for potential acquisitions, which could involve
consideration substantially in excess of amounts previously paid by Culligan
for acquisitions, may be paid in cash, through the issuance of Culligan Common
Stock (which would increase the number of shares of Culligan Common Stock
outstanding) or other securities of Culligan, borrowings, or a combination
thereof. There can be no assurance that Culligan will be able to make
acquisitions on terms favorable to Culligan. With respect to recently
completed and potential future acquisitions, Culligan may encounter various
associated risks, including the possible inability to integrate an acquired
business into Culligan's manufacturing systems, increased goodwill
amortization, increased leverage, diversion of management's attention and
unanticipated problems or liabilities, some or all of which could have a
material adverse effect on Culligan's operations and financial performance.
 
  Competition. The markets in which Culligan competes are highly competitive.
Culligan competes with many domestic and international companies in its global
markets. The principal methods of competition in the markets in which Culligan
competes are distribution capabilities, product specifications, product
knowledge and reputation, technology, service and price. Culligan has a
significant number of competitors, some of which have greater resources than
Culligan.
 
  Technological and Regulatory Change. The water purification and treatment
business is characterized by changing technology, competitively imposed
process standards and regulatory requirements, each of which influences the
demand for Culligan's products and services. Changes in regulatory or
industrial requirements may render certain of Culligan's purification and
treatment products and processes obsolete. Acceptance of new products may also
be affected by the adoption of new government regulations requiring stricter
standards. Culligan's ability to anticipate changes in technology and
regulatory standards and to successfully develop and introduce new and
enhanced products on a timely basis will be a significant factor in Culligan's
ability to grow and to remain competitive. There can be no assurance that
Culligan will be able to achieve the technological advances that may be
necessary for it to remain competitive or that certain of its products will
not become obsolete. In addition, Culligan is subject to the risks generally
associated with new product introductions and applications, including lack of
market acceptance, delays in development or failure of products to operate
properly.
 
  Risks Associated with International Operations. Approximately 36% of
Culligan's net sales for fiscal 1997 were derived from operations conducted
outside of the United States. Culligan's operations may be affected by
economic, political and governmental conditions in some of the countries where
Culligan has manufacturing facilities and where its products are marketed. In
addition, changes in economic or political conditions in any of the countries
in which Culligan operates could result in unfavorable exchange rates, new or
additional currency or exchange controls or other restrictions being imposed
on the operations of Culligan. Similarly, Culligan's operations may be
adversely affected by significant fluctuations in the value of the United
States dollar against certain foreign currencies, and the enactment of
exchange controls or foreign governmental or regulatory restrictions on the
transfer of funds.
 
  Restrictive Covenants. Culligan's credit facility requires it to achieve and
maintain certain financial ratios. In addition, the credit facility contains
numerous financial and operating covenants, including restrictions on the
ability of Culligan to incur indebtedness, to merge, consolidate or transfer
all or substantially all of its assets, to make certain sales of assets and to
create, incur or permit the existence of certain liens. Such financial ratios,
restrictions and covenants may affect the operating flexibility of Culligan.
Further, the failure to maintain the ratios or to comply with the covenants
would result in a default and permit the lenders under the credit facility to
accelerate the maturity of the indebtedness governed by the credit facility
and related instruments.
 
  Controlling Stockholders. Prior to giving effect to the Merger, affiliates
of Apollo Advisors, L.P. (collectively "Apollo") beneficially own
approximately 34% of the outstanding Culligan Common Stock (approximately 29%
after giving effect to the Merger). By reason of such percentage ownership,
Apollo may
 
                                      33
<PAGE>
 
have significant control over the management and policies of Culligan. The
level of ownership of the outstanding Culligan Common Stock by Culligan's
principal stockholders may have the effect of making more difficult or of
discouraging, absent the support of such stockholders, a proxy contest, a
merger involving Culligan, a tender offer, an open market purchase program or
other purchases of the Culligan Common Stock that could give holders of such
stock the opportunity to realize a premium over the then-prevailing market
price for their shares of the Culligan Common Stock.
 
  Certain Anti-Takeover Provisions. Certain provisions of the Culligan
Certificate and By-Laws, together or separately, may discourage potential
acquisition proposals, delay or prevent a change in control of Culligan and
limit the price that certain investors might be willing to pay in the future
for shares of the Culligan Common Stock. These provisions include a classified
board of directors, a stockholder rights plan, the ability to issue, without
further stockholder approval, preferred stock with rights and privileges which
would be senior to the Culligan Common Stock and advance notice procedures for
stockholders to nominate candidates for election as directors of Culligan and
submit proposals for consideration at stockholders' meetings. See "DESCRIPTION
OF CULLIGAN CAPITAL STOCK" and "COMPARISON OF RIGHTS OF STOCKHOLDERS."
 
  Shares Eligible for Future Sale. No prediction can be made as to the effect,
if any, that future sales of Culligan Common Stock, or the availability of
Culligan Common Stock for future sales, will have on the market price of the
Culligan Common Stock prevailing from time to time. Sales in the public market
of substantial amounts of Culligan Common Stock (including shares of Culligan
Common Stock acquired upon the exercise of options), or the perception that
such sales could occur, could adversely affect prevailing market prices for
the Culligan Common Stock.
 
  Dividend Policy. Culligan currently anticipates that it will not pay cash
dividends on shares of Culligan Common Stock in the foreseeable future. The
payment of dividends will be a business decision to be made by the Culligan
Board from time to time based on such considerations as the Culligan Board
deems relevant, will be payable only out of funds legally available under the
Delaware General Corporation Law (the "DGCL") and will be subject to any
restrictions which may be contained in Culligan's debt instruments. The
payment of dividends on Culligan Common Stock is currently limited by the
Culligan Credit Facility.

                          THE AMETEK SPECIAL MEETING
 
DATE, TIME AND PLACE; PURPOSE OF MEETING
   
  This Joint Proxy Statement/Prospectus is being furnished in connection with
the solicitation of proxies by the AMETEK Board for use at the AMETEK Special
Meeting. The AMETEK Special Meeting will be held on July 23, 1997 at the
Desmond Great Valley Hotel and Conference Center, One Liberty Boulevard,
Malvern, Pennsylvania 19355, at 2:00 p.m., local time. The AMETEK Special
Meeting will be held for the purpose of considering and voting upon proposals
to (i) approve and adopt the Merger Agreement, the Distribution Agreement, the
Merger and the Spin-Off, (ii) elect eight directors to hold office for the
terms specified in this Joint Proxy Statement/Prospectus and until their
successors are elected and qualified, (iii) approve the appointment of Ernst &
Young LLP as independent auditors for the year 1997 and (iv) transact such
other business as may properly come before the AMETEK Special Meeting or any
adjournments or postponements thereof.     
 
  Management of AMETEK knows of no matters to be brought before the AMETEK
Special Meeting other than those referred to herein. If any other business
should properly come before the AMETEK Special Meeting other than those
referred to herein, the persons named in the proxy will vote in accordance
with their best judgment.
 
  THE AMETEK BOARD UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE FOR THE
APPROVAL AND ADOPTION OF THE MERGER AGREEMENT, THE DISTRIBUTION AGREEMENT, THE
MERGER AND THE SPIN-OFF, AS WELL AS EACH OF THE FOREGOING ADDITIONAL ACTIONS.
 
RECORD DATE
   
  The AMETEK Board has fixed the close of business on June 25, 1997 as the
AMETEK Record Date. Only the holders of record of the outstanding shares of
AMETEK Common Stock on the AMETEK Record Date will be entitled to notice of,
and to vote at, the AMETEK Special Meeting and any adjournments or
postponements thereof. At the AMETEK Record Date,            shares of AMETEK
Common Stock were outstanding and entitled to vote. There were, in addition,
        issued shares held by AMETEK in its treasury which, while so held,
cannot be voted. The presence, in person or by proxy, of a majority of the
aggregate number of shares of AMETEK Common Stock outstanding and entitled to
vote on the AMETEK Record Date is necessary to constitute a quorum at the
AMETEK Special Meeting.     
 
PROXIES; VOTING AND REVOCATION
 
  Shares of AMETEK Common Stock, represented by a properly executed proxy
received prior to the vote at the AMETEK Special Meeting and not revoked, will
be voted at the AMETEK Special Meeting as directed in the proxy. If a proxy is
submitted and no directions are given, the proxy will be voted for the
approval and adoption of the Merger Agreement, the Distribution Agreement, the
Merger and the Spin-Off, and for the additional proposals referred to herein.
AMETEK intends to count shares of AMETEK Common Stock present in person at the
AMETEK Special Meeting but not voting, and shares of AMETEK Common Stock for
which it has received proxies but with respect to which holders of shares have
abstained on any matter, as present at the AMETEK Special Meeting for purposes
of determining the presence or absence of a quorum for the transaction of
business. Since the affirmative vote of the holders of a majority of the
outstanding shares of AMETEK Common Stock entitled to vote on the Merger is
required to approve and adopt the Merger Agreement, the Distribution
Agreement, the Merger and the Spin-Off, such nonvoting shares and abstentions
will have the effect of a vote against the approval of the Merger Agreement,
the Distribution Agreement, the Merger and the Spin-Off. In addition, under
the rules of the NYSE, brokers who hold shares in street name for customers
who are the beneficial owners of such shares are prohibited from giving a
proxy to vote shares held for such customers with respect to the approval and
adoption of the Merger Agreement, the Distribution Agreement, the Merger and
the Spin-Off without specific instructions from such customers. The enclosed
proxy also serves as the voting
 
                                      35
<PAGE>
 
instruction card for the trustees who hold shares of record for participants
in the AMETEK Savings and Investment Plan. Shares for which no instructions
are received by the trustee will be voted in the same proportion as the shares
for which the trustee receives instructions. Therefore, it is imperative to
the consummation of the Merger that you return your proxy card. The AMETEK
Board and management recommend you vote FOR on all items on the proxy.
 
  Each share of AMETEK Common Stock is entitled to one vote with respect to
the proposal to approve and adopt the Merger Agreement, the Distribution
Agreement, the Merger and the Spin-Off. The persons named as proxies by a
stockholder may propose and vote for one or more adjournments or postponements
of the AMETEK Special Meeting to permit further solicitation of proxies in
favor of such proposal; provided, however, that no proxy that is voted against
the proposal to approve and adopt the Merger Agreement, the Distribution
Agreement, the Merger and the Spin-Off will be voted in favor of any such
adjournment or postponement. Votes are tabulated at the AMETEK Special Meeting
by inspectors of election.
 
  A stockholder of record may revoke a proxy at any time prior to its being
voted by filing an instrument of revocation with Donna F. Winquist, Corporate
Secretary of AMETEK (AMETEK, Inc., Station Square, Paoli, Pennsylvania 19301),
by filing a duly executed proxy bearing a later date, or by appearing at the
AMETEK Special Meeting in person, notifying the Secretary, and voting by
ballot at the AMETEK Special Meeting. Any stockholder of record attending the
AMETEK Special Meeting may vote in person whether or not a proxy has been
previously given, but the mere presence (without notifying the Secretary of
AMETEK) of a stockholder at the AMETEK Special Meeting will not constitute
revocation of a previously given proxy. In addition, stockholders who hold
shares of AMETEK Common Stock that are not registered in their own name will
need additional documentation from the record holder of such shares to vote
personally at the AMETEK Special Meeting.
 
REQUIRED VOTES; PRINCIPAL STOCKHOLDERS
 
  The affirmative vote of the holders of a majority of shares of AMETEK Common
Stock issued, outstanding and entitled to vote at the AMETEK Special Meeting
is necessary to approve and adopt the Merger Agreement, the Distribution
Agreement, the Merger and the Spin-Off. Such approval by holders of AMETEK
Common Stock is a condition to the consummation of the Spin-Off and the
Merger.
 
  As of the AMETEK Record Date,         shares of AMETEK Common Stock were
outstanding and entitled to vote. Of such shares,     , or approximately  %,
were held by directors and executive officers of AMETEK, its subsidiaries and
their respective affiliates, all of which they intend to vote for approval of
the Merger Agreement, the Distribution Agreement, the Merger and the Spin-Off.
 
  Information with respect to beneficial ownership of AMETEK Common Stock by
entities owning more than 5.0% of such stock and more detailed information
with respect to beneficial ownership of AMETEK Common Stock by AMETEK
directors and executive officers are incorporated by reference to the AMETEK
10-K. See "AVAILABLE INFORMATION" and "INCORPORATION OF CERTAIN INFORMATION BY
REFERENCE." Such information is also set forth in the section entitled
"INFORMATION AS TO NOMINEES FOR ELECTION OF DIRECTORS--Stock Ownership," which
is included in this Joint Proxy Statement/Prospectus.
 
SOLICITATION OF PROXIES
 
  The expense of printing and mailing this Joint Proxy Statement/Prospectus
and the material used in this solicitation of proxies will be borne equally by
Culligan and AMETEK. These expenses and certain other transaction expenses are
subject to a cap of $1,500,000 in the case of Culligan. It is contemplated
that AMETEK proxies will be solicited through the mail and directly by
officers, directors, and regular employees of Culligan and AMETEK. AMETEK will
reimburse banks, brokerage houses and other custodians, nominees and
fiduciaries for their reasonable expenses in forwarding these proxy materials
to the principals. AMETEK has engaged Georgeson & Company, Inc. to represent
it in connection with the solicitation of proxies at a cost of approximately
$10,000 plus expenses.

                                 PROPOSAL (1)
 
                    APPROVAL OF THE MERGER AND THE SPIN-OFF
 
       THE AMETEK BOARD RECOMMENDS A VOTE FOR APPROVAL OF THIS PROPOSAL
 
                   BACKGROUND OF THE SPIN-OFF AND THE MERGER
 
  AMETEK regularly evaluates strategic alternatives with respect to its
distinct lines of business with a view toward enhancing stockholder value. In
April 1996, representatives of Culligan first approached AMETEK's Chief
Financial Officer, John J. Molinelli, with an unsolicited expression of
interest in purchasing the Water Filtration Business. AMETEK's management
believed that the valuations then being proposed by Culligan for the Water
Filtration Business were too low. However, informal discussions among Culligan
and AMETEK representatives continued into July 1996. During this period,
Culligan solicited from its investment bankers an estimated range of values
for the Water Filtration Business based on the limited public information then
available to it. At its July 1996 meeting, the AMETEK Board reviewed with
management the initial valuations proposed by Culligan and concurred with
management's view that those valuations were insufficient to warrant further
discussions.
 
  In August 1996, Culligan, through certain investment banking contacts,
reinitiated discussions with AMETEK regarding a possible acquisition of the
Water Filtration Business at a higher valuation then previously discussed.
Regular discussions continued over the next month during which time
alternative structures were suggested for the Culligan acquisition of the
Water Filtration Business. In early October 1996, Culligan and AMETEK executed
a confidentiality agreement at which point AMETEK provided Culligan with an
initial package of financial information regarding the Water Filtration
Business. In late October 1996, Culligan advised AMETEK that, based on the
information so far provided, it had increased its valuation of the Water
Filtration Business, and that a further increase in this valuation might be
possible based on additional information it was requesting.
 
  In early November 1996, Walter Blankley, the Chief Executive Officer of
AMETEK, and Douglas Pertz, the Chief Executive Officer of Culligan, met to
discuss various issues relating to the proposed transaction, including
valuation of the Water Filtration Business. Following this meeting, Culligan
provided AMETEK with a list of issues it wished to address relating to the
Water Filtration Business and the financial information it had received so
far. In mid-November 1996, Mr. Blankley and other members of AMETEK's
management met with Culligan's management to review these issues. Mr. Blankley
reviewed the status of the Culligan negotiations with the AMETEK Board during
its meeting on November 20, 1996. The AMETEK Board evaluated the potential
transaction with Culligan, as well as other strategic alternatives for the
Water Filtration Business. In considering the possibility of a transaction
with Culligan, the AMETEK Board evaluated the feasibility of using a structure
under which all of AMETEK's assets and operations, other than the Water
Filtration Business's assets and operations, would be spun-off to stockholders
in a tax-free distribution followed by the acquisition of the Water Filtration
Business by Culligan in a tax-free stock-for-stock merger. The AMETEK Board
authorized Mr. Blankley to explore this structure with Culligan.
 
  In early December 1996, Messrs. Blankley and Pertz met to discuss the
valuation of a transaction based on the proposed structure. Although this
meeting did not produce an agreement on value, it did result in a narrowing of
the gap between the valuations proposed by Culligan and AMETEK as well as an
understanding that such structure would be the only viable approach for the
parties to pursue. Following the meeting, Culligan summarized the valuation
range and the other principal terms of the transaction in a draft term sheet
which it distributed in mid-December 1996. Culligan and AMETEK decided that,
although no agreement had been reached on valuation or price, work should
proceed on other aspects of the proposed transaction. Culligan then began its
due diligence review of the Water Filtration Business and discussions ensued
between Culligan's representatives and advisors and AMETEK's representatives
and advisors on structuring and documentation issues.

  Pursuant to a letter agreement dated January 27, 1997, AMETEK engaged
Goldman Sachs to review the proposed transaction with Culligan and provide the
AMETEK Board with its analysis of whether the consideration to be received in
the Merger was fair to the AMETEK stockholders.
   
  In January 1997, the AMETEK Board invited several AMETEK advisors, including
members of Stroock & Stroock & Lavan LLP and Goldman Sachs, to attend its
regularly scheduled board meeting in order to discuss timing, structuring and
valuation issues relating to the proposed acquisition of the Water Filtration
Business by Culligan. In mid-January, Culligan provided AMETEK and its
advisors with a draft of the Merger Agreement and the parties commenced
negotiating the terms of the Merger Agreement and the related transaction
documents. The AMETEK Board held two telephonic meetings, on January 29 and
February 1, 1997, to review the status of the negotiations, including the
continuing negotiations with respect to valuation of the Water Filtration
Business. On February 4, 1997, the AMETEK Board held another meeting by
telephone during which the proposed terms of the Merger and the related
transactions were reviewed, including the proposed agreement reached by
Messrs. Blankley and Pertz regarding valuation and price. Goldman Sachs
provided the AMETEK Board with its preliminary view that, based on the terms
of the transaction as they were understood by Goldman Sachs, and subject to
finalization of the transaction terms and review of the final documentation,
the Merger consideration would be fair to the AMETEK stockholders. AMETEK's
counsel, Stroock & Stroock & Lavan LLP, provided a review of the documentation
as well as various tax, regulatory and other legal matters. Following these
presentations and a general discussion, the AMETEK Board unanimously approved
the terms of the transaction with Culligan and authorized the execution of the
Merger Agreement and related documentation. On February 5, 1997, Culligan and
AMETEK executed the Merger Agreement, and AMETEK and New Ametek executed the
Distribution Agreement. Following review of the final transaction terms and
final definitive documents, Goldman Sachs delivered its written opinion, dated
February 5, 1997, to the effect that the Exchange Ratio pursuant to the Merger
Agreement was fair to the holders of AMETEK Common Stock. On May 9, 1997 the
Merger Agreement and the Distribution Agreement were amended and restated.

        REASONS FOR THE TRANSACTION; RECOMMENDATION OF THE AMETEK BOARD
 
  The AMETEK Board has determined that the Spin-Off and the Merger create
stockholder value and are fair and in the best interests of the AMETEK
stockholders. The AMETEK Board has therefore approved the Merger Agreement and
the Distribution Documents, and unanimously recommends the approval and
adoption of the Merger Agreement, the Distribution Agreement, the Merger and
the Spin-Off by the AMETEK stockholders. In reaching this determination and
recommendation, the AMETEK Board consulted with AMETEK's management, as well
as its legal counsel and financial advisors, and considered the following
factors:
 
    (a) the terms and conditions of the Merger Agreement and the Distribution
  Agreement, including the amount and form of consideration, which includes
  approximately .11 shares of Culligan Common Stock and one share of New
  Ametek Common Stock for each share of AMETEK Common Stock;
 
    (b) the fact that the Spin-Off and the Merger allow AMETEK stockholders
  on a tax-free basis to retain a continuing interest in two successful and
  growing businesses by retaining (i) an interest in the Water Filtration
  Business through their ownership of Culligan Common Stock after the Merger
  and (ii) an interest in AMETEK's electromechanical, precision instruments
  and other businesses through their ownership of New Ametek Common Stock
  following the Spin-Off;
 
    (c) the ability of the parties to structure a transaction which would be
  tax-free to AMETEK and its stockholders;
 
    (d) the belief that the Water Filtration Business when combined with
  Culligan, a leading water filtration company, would be able to compete more
  effectively in the water filtration market than it would as a division of
  AMETEK, especially taking into account the increased economies of scale of
  the combined operation and Culligan's extensive distribution channels and
  experience in the retail market;
 
    (e) the belief that AMETEK, because of its relative lack of experience in
  the retail markets, would not be able to fully exploit the Water Filtration
  Business's potential for growth in the retail market without a substantial
  investment in advertising and a significant expansion of its distribution
  capabilities;
 
    (f) the desire to refocus and simplify AMETEK's business based on the
  belief that the public markets have found it difficult to value AMETEK
  because of the number and diversity of its various business segments; and
 
    (g) financial presentations of Goldman Sachs made to the AMETEK Board and
  the preliminary view of Goldman Sachs to the effect that the Exchange Ratio
  pursuant to the Merger Agreement was fair to the AMETEK stockholders.
 
  The foregoing discussion of the reasons and factors considered and given
weight by the AMETEK Board is not intended to be exhaustive, but is believed
to include all of the material factors considered by the AMETEK Board. In view
of the variety of factors considered in connection with its consideration of
the Merger, the AMETEK Board did not find it practicable to and did not
quantify or otherwise assign relative weights to the specific factors
considered in reaching its determination. In addition, individual members of
the AMETEK Board may have given different weight to different factors.

                       OPINION OF THE FINANCIAL ADVISOR
 
  Goldman Sachs delivered its written opinion dated February 5, 1997 to the
AMETEK Board that as of the date of such opinion, the Exchange Ratio pursuant
to the Merger Agreement was fair to the holders of AMETEK Common Stock.
 
  The full text of the written opinion of Goldman Sachs dated February 5,
1997, which sets forth assumptions made, matters considered and limitations on
the review undertaken in connection with the opinion, is attached hereto as
Appendix C to this Joint Proxy Statement/Prospectus; and is incorporated
herein by reference. Stockholders of AMETEK are urged to, and should, read
such opinion in its entirety. Goldman Sachs' written opinion is addressed to
the AMETEK Board and does not constitute a recommendation to an AMETEK
stockholder as to how such stockholder should vote at the AMETEK Special
Meeting and should not be relied upon by any stockholder as such.
   
  In connection with its opinion, Goldman Sachs reviewed, among other things,
(i) the Merger Agreement; (ii) the Annual Reports to Stockholders and Annual
Reports on Form 10-K of AMETEK for the five years ended December 31, 1995 and
of Culligan for the fiscal year ended January 31, 1996; (iii) certain interim
reports to stockholders and Quarterly Reports on Form 10-Q of AMETEK and
Culligan; and (iv) certain internal financial analyses and forecasts for the
Water Filtration Business prepared by AMETEK's management. Goldman Sachs also
held discussions with members of the senior management of AMETEK, the Water
Filtration Business and Culligan regarding the past and current business
operations, financial condition, and future prospects, of AMETEK and Culligan.
In addition, Goldman Sachs reviewed the reported price and trading activity
for Culligan Common Stock, compared certain financial and stock market
information for AMETEK with similar information for certain other companies
the securities of which are publicly traded, reviewed the financial terms of
certain recent business combinations in the water filtration industry
specifically and in other industries generally and performed such other
studies and analyses as it considered appropriate.     
 
  Goldman Sachs relied without independent verification upon the accuracy and
completeness of all of the financial and other information reviewed by it for
purposes of its opinion. In addition, Goldman Sachs did not make an
independent evaluation or appraisal of the assets and liabilities of the Water
Filtration Business or Culligan or any of its subsidiaries and Goldman Sachs
was not furnished with any such evaluation or appraisal. Goldman Sachs was not
asked to solicit, and accordingly did not solicit, third parties with respect
to potential alternative transactions. Goldman Sachs assumed, with AMETEK's
consent, that the Merger would be tax-free to AMETEK and its stockholders.
 
  The following is a summary of certain of the financial analyses used by
Goldman Sachs in connection with providing its written opinion to the AMETEK
Board on February 5, 1997.
 
  (i) Historical Stock Trading Analysis. Goldman Sachs reviewed the historical
trading prices and volumes for the Culligan Common Stock.
 
  (ii) Selected Companies Analysis. Goldman Sachs reviewed and compared
certain financial information relating to Culligan to corresponding financial
information, ratios and public market multiples for four large capitalization
publicly traded corporations: Ionics Inc., Millipore Corporation, Pall
Corporation, United States Filter Corporation (the "Large Cap Selected
Companies"); and three small capitalization publicly traded companies: Cuno
Inc., Memtec Limited and Osmonics Inc. (the "Small Cap Selected Companies" and
together with the Large Cap Selected Companies, the "Selected Companies"). The
Selected Companies were chosen because they are publicly traded companies with
operations that for purposes of analysis may be considered similar to
Culligan. Goldman Sachs calculated and compared various financial multiples
and ratios. The multiples of Culligan were calculated using a price of $36.38
per share, the closing price of Culligan Common Stock on the NYSE on February
4, 1997. The multiples and ratios for Culligan were based on information
provided by
 
                                      40
<PAGE>
 
Culligan's management and the multiples for each of the Selected Companies
were based on the most recent publicly available information. With respect to
the Selected Companies, Goldman Sachs considered levered market capitalization
(i.e., market value of common equity plus estimated market value of debt less
cash) as a multiple of LTM sales, as a multiple of LTM earnings before
interest, taxes, depreciation and amortization ("EBITDA") and as a multiple of
LTM earnings before interest and taxes ("EBIT"). Goldman Sachs' analyses of
the Selected Companies indicated levered multiples of LTM sales, which ranged
from 1.49x to 3.25x for the Large Cap Selected Companies and from 1.37x to
2.28x for the Small Cap Selected Companies, LTM EBITDA, which ranged from
10.8x to 21.1x for the Large Cap Selected Companies and from 14.0x to 25.2x
for the Small Cap Selected Companies, and LTM EBIT, which ranged from 13.2x to
29.6x for the Large Cap Selected Companies and from 14.0x to 25.2x for the
Small Cap Selected Companies, compared to levered multiples of 2.27x, 14.5x
and 17.6x, respectively, for Culligan. Goldman Sachs also considered for the
Selected Companies LTM price/earnings ratios, which ranged from 18.5x to 53.5x
for the Large Cap Selected Companies and from 19.0x to 29.9x for the Small Cap
Selected Companies compared to 28.6x for Culligan; estimated calendar year
1996 and 1997 price/earnings ratios, which ranged from 17.7x to 49.7x for the
Large Cap Selected Companies and from 22.1x to 23.8x for the Small Cap
Selected Companies for estimated calendar year 1996 and 15.3x to 32.1x for the
Large Cap Selected Companies and from 18.5x to 20.5x for the Small Cap
Selected Companies for estimated calendar year 1997 compared to 26.5x and
22.1x, respectively, for Culligan; LTM EBIT margins and LTM EBITDA margins,
which ranged from 5.0% to 20.9% for the Large Cap Selected Companies and from
6.3% to 12.9% for the Small Cap Selected Companies and 7.1% to 25.7% for the
Large Cap Selected Companies and from 11.8% to 14.2% for the Small Cap
Selected Companies, respectively, compared to 12.9% and 15.7%, respectively,
for Culligan.
 
  (iii) Discounted Cash Flow Analysis. Goldman Sachs performed a discounted
cash flow analysis using AMETEK'S management projections. Goldman Sachs
calculated a net present value of future cash flows for the years 1997 through
2001 using a half-year convention and discount rates ranging from 10% to 14%.
Goldman Sachs calculated net present values of AMETEK'S terminal values in the
year 2001 using perpetuity growth rates of 3% to 7% and discount rates ranging
from 10% to 14%. The various ranges for discount rates and perpetuity growth
rates were chosen to reflect theoretical analyses of cost of capital and long-
term prospects for AMETEK, respectively.
 
  Based on the analysis above, the implied values for AMETEK ranged from
$144.8 million to $167.7 million with a mid-range of $155.8 million.
 
  (iv) Selected Transactions Analysis. Goldman Sachs analyzed certain
information relating to selected transactions in the water
purification/filtration industry since 1992 (the "Selected Transactions").
Such analysis indicated that for the Selected Transactions (i) levered
aggregate consideration as a multiple of LTM revenues ranged from 0.45x to
2.48x, as compared to 2.26x for the levered aggregate consideration to be
received in the Merger, (ii) the multiple of LTM EBITDA ranged from 7.0x to
22.0x, as compared to 10.5x for the levered aggregate consideration to be paid
in the Merger, and (iii) levered aggregate consideration as a multiple of LTM
EBIT ranged from 7.7x to 41.0x, as compared to 12.3x for the aggregate
consideration to be paid in the Merger.
 
  (v) Contribution Analysis. Goldman Sachs reviewed certain historical and
estimated future operating and financial information (including, among other
things, revenues, EBITDA, EBIT, net income and tangible assets) for AMETEK,
Culligan and the pro forma combined entity resulting from the Merger based on
AMETEK's historical 1996 results, and Culligan managements' consensus
financial forecasts for 1997. The analysis indicated that the AMETEK
stockholders would receive 14.0% of the outstanding common equity of the
combined companies after the Merger. Goldman Sachs also analyzed the relative
income statement contribution of AMETEK and Culligan to the combined companies
on a pro forma basis and before taking into account any of the possible
benefits that may be realized following the Merger based on actual 1996
results for AMETEK and estimated 1997 results for Culligan, based on financial
data provided to Goldman Sachs by the management of AMETEK and Culligan. This
analysis indicated that using such 1996/1997 numbers AMETEK would have
contributed 15.7% to combined revenues, 19.9% to combined EBITDA, 20.1% to
combined EBIT, and 17.1% to combined net income.

  The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. Selecting
portions of the analyses or of the summary set forth above, without
considering the analyses as a whole, could create an incomplete view of the
processes underlying Goldman Sachs' opinion. In arriving at its fairness
determination, Goldman Sachs considered the results of all such analyses. No
company or transaction used in the above analyses as a comparison is identical
to AMETEK, the Water Filtration Business or Culligan or the contemplated
transaction. The analyses were prepared solely for purposes of Goldman Sachs'
providing its opinion to the AMETEK Board as to the fairness of the Exchange
Ratio to the AMETEK Board and do not purport to be appraisals or necessarily
reflect the prices at which businesses or securities actually may be sold.
Analyses based upon forecasts of future results are not necessarily indicative
of actual future results, which may be significantly more or less favorable
than suggested by such analyses. Because such analyses are inherently subject
to uncertainty, being based upon numerous factors or events beyond the control
of the parties or their respective advisors, none of AMETEK, Culligan, Goldman
Sachs or any other person assumes responsibility if future results are
materially different from those forecast.
   
  As described above, Goldman Sachs' presentation of its preliminary view to
the AMETEK Board was one of many factors taken into consideration by the
AMETEK Board in making its determination to approve the Merger Agreement. The
foregoing summary does not purport to be a complete description of the
analysis performed by Goldman Sachs and is qualified by reference to the
written opinion of Goldman Sachs set forth in Appendix C hereto.     
 
  Goldman Sachs, as part of its investment banking business, is continually
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, negotiated underwritings, competitive biddings,
secondary distributions of listed and unlisted securities, private placements,
and valuations for estate, corporate and other purposes. AMETEK selected
Goldman Sachs as its financial advisor because it is a nationally recognized
investment banking firm that has substantial experience in transactions
similar to the Merger.
 
  Goldman Sachs provides a full range of financial, advisory and brokerage
services and in the course of its normal trading activities may from time to
time effect transactions and hold positions in the securities or options on
securities of AMETEK and/or Culligan for its own account and for the account
of customers. In addition, Goldman Sachs has provided certain investment
banking services to Culligan from time to time, including having acted as
managing underwriter of Culligan's initial public offering in December 1995
and of a secondary sale of Culligan Common Stock in October 1996.
 
  Pursuant to a letter agreement dated January 27, 1997 (the "Engagement
Letter"), AMETEK engaged Goldman Sachs to act as its financial advisor in
connection with the contemplated transaction. Pursuant to the terms of the
Engagement Letter, AMETEK has agreed to pay Goldman Sachs upon delivery of its
fairness opinion a fee of $350,000. AMETEK has agreed to reimburse Goldman
Sachs for its reasonable out-of-pocket expenses, including attorney's fees,
and to indemnify Goldman Sachs against certain liabilities, including certain
liabilities under the federal securities laws.

                             THE MERGER AGREEMENT
 
  The following is a summary description of certain aspects of the Merger and
certain terms of the Merger Agreement, which is included as Appendix A to this
Joint Proxy Statement/Prospectus and is incorporated herein by reference.
Certain capitalized terms used herein and not defined have the meanings
ascribed to them in the Merger Agreement. This summary does not purport to be
complete and is qualified in its entirety by reference to the Merger
Agreement.
 
THE MERGER
 
  At the Effective Time, Culligan, AMETEK and Culligan Merger Sub will
consummate the Merger whereby Culligan Merger Sub will be merged with and into
AMETEK and the separate corporate existence of Culligan Merger Sub will cease.
AMETEK will be the surviving corporation in the Merger and will be a wholly
owned subsidiary of Culligan.
 
 Effective Time; Closing
 
  The Merger will become effective upon the filing of the Certificate of
Merger with the Secretary of State of the State of Delaware or at such other
time as is provided in the Certificate of Merger. The closing of the Merger
will take place as promptly as practicable (and in any event within two
business days) after satisfaction or waiver of certain conditions contained in
the Merger Agreement and at least one day after the Spin-Off (the "Closing
Date"). See "--Conditions."
 
 Certificate of Incorporation and By-Laws
 
  The AMETEK Certificate in effect immediately prior to the Effective Time
will be amended and restated in its entirety to read as set forth in Exhibit A
of the Merger Agreement and, as amended, will be the Certificate of
Incorporation of the Surviving Corporation until amended in accordance with
its terms and applicable law. The By-Laws of Culligan Merger Sub in effect at
the Effective Time will be the By-Laws of the Surviving Corporation until
amended in accordance with their terms and applicable law.
 
 Directors and Officers
 
  The directors of Culligan Merger Sub at the Effective Time will be the
directors of the Surviving Corporation, each to hold office from the Effective
Time in accordance with the Certificate of Incorporation and By-Laws of the
Surviving Corporation and until his successor is duly elected and qualified.
The officers of Culligan Merger Sub at the Effective Time will be the officers
of the Surviving Corporation, each to hold office from the Effective Time in
accordance with the Certificate of Incorporation and By-Laws of the Surviving
Corporation and until his successor is duly appointed and qualified.
 
CONVERSION OF AMETEK COMMON STOCK
   
  At the Effective Time, each issued and outstanding share of AMETEK Common
Stock will be converted into the right to receive the number (rounded to the
nearest one-thousandth of a share) of fully paid and nonassessable shares of
Culligan Common Stock determined by dividing (i) the Net Equity Value divided
by (ii) $37.50, divided by (iii) the number of shares of AMETEK Common Stock
outstanding at the Effective Time. "Net Equity Value" means an amount equal to
(A) $155,000,000 minus (B) the amount, $25 million, of the Retained Debt.
Based on the foregoing calculation, the Net Equity Value will be $130,000,000.
       
  If the number of shares of AMETEK Common Stock outstanding on the Spin-Off
Record Date were to equal 32,903,451 (the number of such shares outstanding on
June 13, 1997), then each share of AMETEK Common Stock would be converted into
approximately .11 shares of Culligan Common Stock. Assuming the exercise of
all exercisable AMETEK stock options on June 13, 1997, the total number of
shares of AMETEK Common Stock outstanding would equal 34,194,164, in which
case each share of AMETEK Common Stock would be converted into approximately
 .10 shares of Culligan Common Stock. However, additional shares of AMETEK
Common Stock may be issued prior to the Effective Time, including pursuant to
the exercise of AMETEK stock options. Therefore, the amount of Culligan Common
Stock received per share of AMETEK Common Stock in the Merger may vary.     
 
                                      43
<PAGE>
 
  Because the Exchange Ratio is based on a fixed-price of $37.50 for Culligan
Common Stock and the market price for Culligan Common Stock fluctuates, the
value of the Culligan Common Stock that holders of AMETEK Common Stock will
receive in the Merger increases as the market price of Culligan Common Stock
increases and decreases as the market price of Culligan Common Stock
decreases. In addition, because additional shares of AMETEK Common Stock may
be issued prior to the Effective Time, the value of the consideration per
share received by holders of AMETEK Common Stock in the Merger may decrease.
The AMETEK Board and the Culligan Board determined the Merger consideration
through arm's length negotiations.
 
  All shares of AMETEK Common Stock, when so converted, will no longer be
outstanding and will automatically be canceled and retired and will cease to
exist, and each holder of a certificate representing any such shares will
cease to have any rights with respect thereto, except the right to receive the
shares of Culligan Common Stock and any cash in lieu of fractional shares of
Culligan Common Stock to be issued or paid in consideration therefor upon the
surrender of such certificate in accordance with the terms of the Merger
Agreement, without interest.
 
  If after the date of the Merger Agreement and prior to the Effective Time,
the outstanding shares of Culligan Common Stock have been changed into a
different number of shares or a different class, by reason of any stock
dividend, split, or any other distribution of shares, the Exchange Ratio will
be correspondingly adjusted.
 
 Exchange of Certificates
 
  As soon as practicable after the Effective Time, the Surviving Corporation
will cause the Exchange Agent to mail to each holder of record of
certificates, which immediately prior to the Effective Time represented
outstanding shares of AMETEK (the "Certificates"), whose shares were converted
into the right to receive shares of Culligan Common Stock (i) a letter of
transmittal and (ii) instructions for effecting the surrender of the
Certificates in exchange for certificates representing shares of Culligan
Common Stock. HOLDERS OF AMETEK COMMON STOCK ARE REQUESTED NOT TO SURRENDER
THEIR CERTIFICATES FOR EXCHANGE UNTIL SUCH LETTER OF TRANSMITTAL AND
INSTRUCTIONS ARE RECEIVED. Upon surrender of a Certificate for cancellation to
the Exchange Agent, together with such letter of transmittal, duly executed,
the holder of such Certificate will be entitled to receive in exchange
therefor (A) a certificate representing that number of whole shares of
Culligan Common Stock which such holder has the right to receive pursuant to
the terms of Merger Agreement and (B) cash in lieu of any fractional shares of
Culligan Common Stock to which such holder is entitled, after giving effect to
any required tax withholdings. Until surrendered, each Certificate will be
deemed at any time after the Effective Time to represent only the right to
receive upon such surrender a certificate representing shares of Culligan
Common Stock and cash in lieu of any fractional shares of Culligan Common
Stock.
 
  No dividends or other distributions declared or made after the Effective
Time with respect to Culligan Common Stock with a record date after the
Effective Time will be paid to the holder of any unsurrendered Certificate,
and no cash payment in lieu of fractional shares will be paid to any such
holder until the holder of record of such Certificate surrenders such
Certificate. Subject to the effect of applicable laws, following surrender of
any such Certificate, there will be paid to the record holder of the
Certificates representing whole shares of Culligan Common Stock issued in
exchange therefor, without interest, (i) at the time of such surrender, the
amount of any cash payable in lieu of any fractional share of Culligan Common
Stock to which such holder is entitled and the amount of dividends or other
distributions with a record date after the Effective Time theretofore paid
with respect to such whole shares of Culligan Common Stock, and (ii) at the
appropriate payment date, the amount of dividends or other distributions with
a record date after the Effective Time but prior to such surrender and a
payment date subsequent to surrender payable with respect to such whole shares
of Culligan Common Stock.
 
 Cash in Lieu of Fractional Shares
 
  No certificate or scrip representing fractional shares of Culligan Common
Stock will be issued upon the surrender for exchange of Certificates, and such
fractional share interests will not entitle the owner thereof to
 
                                      44
<PAGE>
 
vote or to any rights of a stockholder of Culligan. In lieu of any such
fractional shares, each holder of AMETEK Common Stock who would otherwise have
been entitled to a fraction of a share of Culligan Common Stock upon surrender
of Certificates for exchange will be entitled to receive a cash payment in an
amount equal to such fractional interest multiplied by the Average Culligan
Share Price. "Average Culligan Share Price" is an amount equal to the average
of the closing prices of the Culligan Common Stock on the NYSE Composite
Transactions Reporting System, as reported in The Wall Street Journal, for the
ten (10) trading days ending on the second trading day immediately before the
Effective Time.
 
CERTAIN PRE- AND POST-MERGER TRANSACTIONS
 
 Distribution Documents
 
  Prior to the Spin-Off, AMETEK will, and will cause New Ametek to, execute
and deliver the Trademark Agreement (the "Trademark Agreement"), the Tax
Allocation Agreement (the "Tax Allocation Agreement"), the Transition Services
Agreement (the "Transition Services Agreement") and the Indemnification
Agreement (the "Indemnification Agreement" and together with the Distribution
Agreement, the Trademark Agreement, the Tax Allocation Agreement and the
Transition Services Agreement, the "Distribution Documents"). Prior to the
Spin-Off, Culligan will execute and deliver the Indemnification Agreement. In
connection with the execution of the Merger Agreement, AMETEK and New Ametek
executed the Distribution Agreement. See "THE SPIN-OFF."
 
 The Contributions
   
  Immediately prior to the Spin-Off and pursuant to the terms of the
Distribution Agreement, AMETEK will effect the Contributions. See "THE SPIN-
OFF."     
 
 The Spin-Off
 
  At least one day prior to the Effective Time, and pursuant to the terms of
the Distribution Agreement, AMETEK will effect the Spin-Off. See "THE SPIN-
OFF."
 
 Audited Closing Balance Sheet
 
  Within forty-five (45) days after the Closing Date, New Ametek will deliver
to Culligan the Audited Closing Balance Sheet after giving effect to the Spin-
Off (but not the Merger), which will be audited by New Ametek's independent
public accountants in accordance with United States generally accepted
auditing standards. The Audited Closing Balance Sheet will be prepared in
accordance with generally accepted accounting principles ("GAAP") and, to the
extent consistent with GAAP, on a basis consistent with the Water Filtration
Business Financial Statements. Together with the Audited Closing Balance
Sheet, New Ametek will deliver the Adjusted Closing Balance Sheet which will
be the Audited Closing Balance Sheet adjusted (x) to reflect the financial
position that would have been reported in the Audited Closing Balance Sheet if
it had been prepared in accordance with the items (and accounting principles)
set forth on Schedule 3.4 to the Merger Agreement (which items generally
represent certain differences between GAAP and the basis of presentation of
the Water Filtration Business Financial Statements as specified in the Merger
Agreement) and (y) to exclude any cash paid to AMETEK by New Ametek (or
retained by AMETEK) pursuant to the Distribution Agreement to compensate
Culligan for the Special Offer Amount (as defined in the Distribution
Agreement) and for any unexercised options held by any Water Filtration
Business Employees following the Effective Time (clauses (x) and (y) being
referred to as the "Reference Items"). If, however, a liability or accrual
appears in the Adjusted Closing Balance Sheet which was not identified as a
Reference Item and which was not reflected on the balance sheet included in
the Water Filtration Business Financial Statements, no adjustment will be made
to the extent such liability or accrual is an Assumed Liability (as such term
is defined in the Distribution Agreement). If the Adjusted Net Worth of the
Water Filtration Business as calculated from the Adjusted Closing Balance
Sheet is less than $31,745,000, then New Ametek will pay to the Surviving
Corporation in cash the amount of such shortfall in Adjusted Net Worth within
thirty days of the delivery of the Adjusted Closing Balance Sheet (or, if
later, upon resolution of the matters set forth in the Notice (as defined in
the Merger Agreement)). If the Adjusted
 
                                      45
<PAGE>
 
Net Worth of the Water Filtration Business as calculated from the Adjusted
Closing Balance Sheet is more than $31,745,000, then the Surviving Corporation
will pay New Ametek in cash the amount of such excess up to a maximum amount
of $2,000,000 within thirty days of the delivery of the Adjusted Closing
Balance Sheet (or, if later, upon resolution of the matters set forth in the
Notice). The term "Adjusted Net Worth" means the amount by which consolidated
assets exceed consolidated liabilities, in each instance as set forth on the
Adjusted Closing Balance Sheet.
 
  If Culligan determines that the Audited Closing Balance Sheet is not in
accordance with the Merger Agreement, the parties will endeavor to resolve
their differences within thirty (30) days, failing which Culligan and New
Ametek will select and retain an independent public accounting firm mutually
acceptable to them (or, if they cannot agree on a mutually acceptable firm,
they will cause their respective accounting firms to select such firm) (the
"Third Party Firm") to resolve such differences. The Third Party Firm will be
requested to render a decision within thirty (30) days of its selection and
such decision will be final and binding. The fees and expenses of the Third
Party Firm will be (i) paid by Culligan if less than 25% of the dollar amount
of the Culligan Adjustment (as defined in the Merger Agreement) is required to
be made or (ii) paid by New Ametek if more than 75% of the dollar amount of
the Culligan Adjustment is required to be made or (iii) shared equally by
Culligan and New Ametek if 25% or more but less than 75% of the dollar amount
of the Culligan Adjustment is required to be made.

COVENANTS
 
  During the period from the date of the Merger Agreement and continuing until
the Effective Time, AMETEK agrees as to itself and its subsidiaries that,

Agreement, or to the extent that Culligan will otherwise consent in writing:
 
  (a) AMETEK and its subsidiaries will (i) carry on the Water Filtration

      available the services of the present officers and employees of the
      Water Filtration Business and preserve the relationships with
      customers, suppliers and others having business dealings with the Water
      Filtration Business. AMETEK will consult with Culligan concerning the
      conduct of the Water Filtration Business and will not initiate any new
      marketing plans or make any strategic changes in the conduct of the
      Water Filtration Business without the prior consent of Culligan (which
      consent will not be unreasonably withheld), and Culligan will have the
      right to have representatives present at the facilities of the Water
      Filtration Business during normal business hours and upon reasonable
      prior notice to observe its operations in order to facilitate a
      transition. Notwithstanding the generality of the foregoing, AMETEK
      will, and will cause the Water Filtration Business to, consult with
      Culligan with respect to any decisions, actions or inactions that are
      reasonably expected to result in either (x) a significant deviation in

      and usual course of business consistent with past practice or otherwise
      enter into any material commitment or transaction outside the ordinary
      and usual course of business consistent with past practice, other than
      transactions which are unrelated to the Water Filtration Business and
      which will
 
                                      47

      transactions which are unrelated to the Water Filtration Business and
      which will not materially adversely affect AMETEK's ability to
      consummate the transactions contemplated by the Merger Agreement and
      the Distribution Documents;
 
  (f) AMETEK will not permit the Water Filtration Business, to (i) incur,

      immaterial amendments) or terminate any Compensation and Benefit Plan
      or other employee benefit plan or any agreement, arrangement, plan or
      policy between AMETEK or any of its subsidiaries and one or more of its
      directors, officers or employees and (ii) except for normal increases
      in the ordinary course of business consistent with past practice and
      the payment of bonuses to employees consistent with past practice,

      officer or employee not required by any plan or arrangement as in
      effect as of the date of the Merger Agreement, in each case only to the
      extent that the foregoing relate to the Water Filtration Business or
      its Employees (the "Water Filtration Business Employees");
 
  (h) AMETEK will promptly advise Culligan of any change or development that
      would cause the representation in the Merger Agreement relating to
      undisclosed liabilities to be untrue. AMETEK will promptly provide
      Culligan (or its counsel) copies of all filings made by AMETEK with any
      federal, state or foreign Governmental Entity in connection with the
      Merger Agreement, the Distribution Agreement and the transactions
      contemplated thereby;
 
  (i) AMETEK will not and will not permit the Water Filtration Business to
      change any of its accounting principles, policies or procedures, except
      as may be required by GAAP;
 
  (j) AMETEK will not take or cause or permit to be taken, and will not
      permit any of its subsidiaries to take or cause or permit to be taken,
      any action, or allow to exist any condition, that could (i) disqualify
      the Contributions followed by the Spin-Off as a tax-free reorganization
      pursuant to Section 368(a)(1)(D) of the Code, (ii) disqualify the Spin-
      Off as a tax-free distribution pursuant to Section 355 of the Code, or
      (iii) disqualify the Merger as a tax-free reorganization pursuant to
      Section 368(a) of the Code; and
 
  (k) AMETEK will (i) not engage in or allow transfers of assets or
      liabilities or engage in or enter into other transactions between the
      Water Filtration Business, on the one hand, and New Ametek or any of
      its subsidiaries, on the other hand, except as contemplated by the
      Distribution Agreement or the Tax Allocation Agreement or as to which
      the Water Filtration Business is indemnified pursuant to the
      Indemnification Agreement, (ii) abide and cause New Ametek to abide by
      its respective obligations under the Distribution Agreement, and (iii)
      not terminate or amend, or waive compliance with any obligations under,
      the Distribution Agreement.
 
  During the period from the date of the Merger Agreement and continuing until
the Effective Time, Culligan agrees as to itself and its subsidiaries that:
 
  (a) Culligan will not take any action that would result in any of the
      conditions to the Merger set forth in the Merger Agreement not being
      satisfied or that would materially impair the ability of Culligan to
 
                                      48
<PAGE>
 
     consummate the Merger in accordance with the terms of the Merger
     Agreement or materially delay such consummation;
 
  (b) Culligan will not take or cause or permit to be taken, and will not
      permit any of its subsidiaries to take or cause or permit to be taken,
      any action, or allow to exist any condition, that could (i) disqualify
      the Contributions followed by the Spin-Off as a tax-free reorganization
      pursuant to Section 368(a)(1)(D) of the Code, (ii) disqualify the Spin-
      Off as a tax-free distribution pursuant to Section 355 of the Code, or
      (iii) disqualify the Merger as a tax-free reorganization pursuant to
      Section 368(a) of the Code; and
 
  (c) Culligan will promptly advise AMETEK orally and in writing of any
      change or development that would cause the representation regarding
      certain tax matters contained in the Merger Agreement to be untrue.
      Culligan will promptly provide AMETEK (or its counsel) copies of all
      filings made by Culligan with any federal, state or foreign
      Governmental Entity in connection with the Merger Agreement, the
      Distribution Agreement and the transactions contemplated thereby.
 
COOPERATION
 
  Following the expiration or early termination of the applicable waiting
period under the HSR Act, the parties agree that the business of the Water
Filtration Business will be operated in cooperation between Culligan and
AMETEK and will continue to be managed and administered by AMETEK under the
procedures set forth below:
 
  (a) The appointment, including compensation and contractual agreements, of
      all senior executives of the Water Filtration Business will be made by
      AMETEK following consultation with Culligan. AMETEK will cooperate with
      Culligan on personnel policies and procedures for the Water Filtration
      Business, including, without limitation, setting salary and bonus
      standards, termination and severance policies, and employee benefit
      policies;
 
  (b) AMETEK will cooperate and consult with the financial officers of
      Culligan with respect to policies and procedures relating to financial
      and accounting matters of the Water Filtration Business, including
      without limitation, (i) the preparation of the accounts, books and
      records, (ii) the preparation of financial statements, (iii) the
      monitoring of operating performance under a budget previously prepared,
      and (iv) the preparation and review of monthly management reports;
      provided, however, that AMETEK will not be required to change any such
      policies or procedures;
 
  (c) Culligan and AMETEK will consult with each other in determining the
      best interests of the Water Filtration Business with respect to capital
      expenditures or investments, issuances of guarantees, creation of
      mortgages or liens, establishment of credit lines, or other material
      transactions affecting the Water Filtration Business;
 
  (d) AMETEK will cooperate with the personnel of Culligan in developing
      ongoing sales and marketing strategies and financial and other
      standards for the Water Filtration Business and AMETEK will not
      initiate any new marketing plans or make any strategic changes in the
      operations of the Water Filtration Business without the prior consent
      of Culligan (which consent will not be unreasonably withheld); and
 
  (e) Culligan will have the right to have one or more representatives
      present at the facilities of the Water Filtration Business during
      normal business hours.
 
STOCK EXCHANGE LISTING
 
  Culligan will use its reasonable efforts to cause the shares of Culligan
Common Stock to be issued in the Merger to be approved for listing on the NYSE
and any other national securities exchange on which shares of Culligan Common
Stock may at such time be listed, subject to official notice of issuance,
prior to the Closing Date.

EMPLOYEE MATTERS; EMPLOYEE BENEFIT PLANS
 
  Prior to the Spin-Off, AMETEK will, and will cause its subsidiaries to,
assign to New Ametek or its subsidiaries (or terminate) all employment and
severance agreements with employees of AMETEK who are not Water Filtration
Business Employees. Culligan will, and will cause the Surviving Corporation
to, honor all employee severance plans (or policies) and employment and
severance agreements of AMETEK or any of its subsidiaries as specified in
AMETEK's Disclosure Schedule to the Merger Agreement with respect to the Water
Filtration Business Employees as such agreements (or policies) are in effect
on the date of the Merger Agreement.
 
  Culligan will not have any liability or obligation to or for, except to the
extent described under "THE SPIN-OFF--Terms of the Distribution Agreement--
Employees and Employee Benefit Plans," any employee or former employee of
AMETEK or any of its subsidiaries based upon events, occurrences or services
performed by such employees or former employees on or prior to the Closing
Date and, in the case of employees of AMETEK or any of its subsidiaries other
than Water Filtration Business Employees, following the Closing Date.
 
  As soon as practicable following the Effective Time, Culligan will cause the
Culligan 401(k) Plan to accept a plan-to-plan transfer from AMETEK's 401(k)
Plan (as assumed by New Ametek) of the account balances of the Water
Filtration Business Employees.
 
STOCK OPTIONS
 
  All options to acquire shares of AMETEK Common Stock pursuant to any of the
AMETEK Stock Option or Incentive Plans (other than options held by Water
Filtration Business Employees) which are outstanding immediately prior to the
Effective Time, whether or not then exercisable, will be assumed by New Ametek
as provided in the Distribution Agreement and, except as specifically provided
in the Distribution Agreement, following the Effective Time, will not
represent a right to acquire shares of either Culligan or the Surviving
Corporation. See "THE SPIN-OFF--Terms of the Distribution Agreement--Stock
Option and Stock Incentive Plans."
 
NO SOLICITATION
 
  Until the earlier of the Effective Time or the termination of the Merger
Agreement, AMETEK and its subsidiaries will not, directly or indirectly,
solicit or discuss with any third party (including by way of furnishing non-
public information concerning the Water Filtration Business), or facilitate
any inquiries with respect to an Acquisition Transaction (as defined below);
provided AMETEK may (i) furnish information to, or enter into discussions or
negotiations with, any person or entity that makes an unsolicited proposal
with respect to an AMETEK Acquisition Transaction (as defined below), if, (A)
the AMETEK Board based upon the advice of independent legal counsel,
determines in good faith that such action is necessary for the AMETEK Board to
comply with its fiduciary duties to stockholders under applicable law, and (B)
prior to furnishing such information to, or entering into discussions or
negotiations with, such person or entity, AMETEK provides written notice
thereof to Culligan; or (ii) comply with Rule 14e-2 promulgated under the
Exchange Act with regard to any tender or exchange offer involving AMETEK.
AMETEK will keep Culligan informed on a reasonable basis of the status and
general nature of any discussions or negotiations with respect to an AMETEK
Acquisition Transaction, including any changes to any material terms and
conditions thereof. An Acquisition Transaction means a merger, consolidation,
business combination, sale of a significant amount of assets outside of the
ordinary course of business, sale of shares of capital stock outside of the
ordinary course of business, tender or exchange offer or similar transaction
involving either (i) AMETEK and its subsidiaries, substantially as an entirety
(an "AMETEK Acquisition Transaction") or (ii) the Water Filtration Business.
 
INDEBTEDNESS
 
  Except as reflected on the Retained Business Balance Sheet, AMETEK agrees
that immediately prior to the Effective Time, after giving effect to the
Contributions and the other transactions contemplated by the Distribution
Documents, there will not be outstanding any indebtedness for borrowed money,
or any guarantees in respect of any indebtedness for borrowed money of any
third party, in respect of which the Water Filtration Business is obligated,
other than the Retained Debt.

GOVERNMENT AND REGULATORY APPROVALS
 
  Consummation of the Merger was conditioned upon the expiration or
termination of the waiting period under the HSR Act. On March 14, 1997,
Culligan and AMETEK each filed notification reports under the HSR Act with the
FTC and the Antitrust Division of the DOJ. Early termination of the waiting
period was granted on March 24, 1997.
 
INTERNAL REVENUE SERVICE RULING
   
  The Contributions, the Spin-Off and the Merger were conditioned upon the
issuance by the IRS of the Private Letter Ruling reasonably satisfactory in
form and substance to AMETEK and Culligan substantially to the effect that, on
the basis of the facts, representations and assumptions existing at the
Effective Time: (i) the Contributions followed by the Spin-Off qualify as a
tax-free reorganization pursuant to Section 368(a)(1)(D) of the Code; (ii) the
Spin-Off qualifies as a tax-free distribution pursuant to Section 355(a) of
the Code; and (iii) the Merger qualifies as a tax-free reorganization pursuant
to Section 368 (a)(1)(B) of the Code. The Private Letter Ruling was issued on
June 16, 1997. If the IRS revokes the Private Letter Ruling, this condition
will nevertheless be satisfied if, on or prior to the Closing Date, AMETEK and
Culligan receive the Tax Opinions to the same effect as the Private Letter
Ruling. See "CERTAIN FEDERAL INCOME TAX CONSEQUENCES."

TERMINATION
 
  The Merger Agreement may be terminated at any time prior to the Effective
Time, whether before or after approval of the Merger and the Merger Agreement
by the stockholders of AMETEK:
 
    (a) by mutual consent of Culligan and AMETEK;
 
    (b) by either Culligan or AMETEK if the Merger is not consummated before
  October 31, 1997 (unless due to the action or failure to act of the party
  seeking to terminate the Merger Agreement, which action or failure to act
  constitutes a breach of the Merger Agreement);
 
    (c) by Culligan if (i) there has been a material breach on the part of
  AMETEK in its representations, warranties or covenants set forth in the
  Merger Agreement or the Distribution Agreement, or any material failure by
  AMETEK to comply with its obligations in the Merger Agreement or the
  Distribution Agreement, and, in the case of a material breach of covenant
  or failure to comply which is capable of being cured, is not cured within
  thirty days, (ii) AMETEK's stockholders do not approve of the Merger

  cured, is not cured within thirty days, or (ii) AMETEK's stockholders do
  not approve of the Merger and the Merger Agreement; or
 
    (e) by either Culligan or AMETEK if any change in Federal income tax law

  free treatment.
 
                                      52
<PAGE>
 
  So long as Culligan will not have materially breached its obligations under
the Merger Agreement, AMETEK will pay Culligan $5,000,000, if within twelve
months following the termination of the Merger Agreement pursuant to clause
(c)(ii) or (iii) above or clause (d)(ii) above, AMETEK enters into an
agreement, arrangement or understanding providing for an Acquisition
Transaction. AMETEK will pay the reasonable out-of-pocket expenses incurred by
Culligan in connection with the Merger and the Spin-Off if the Merger Agreement
terminates pursuant to clause (c) above (other than by reason of a breach of
the representations and warranties relating to certain tax matters) or clause
(d)(ii) above. Culligan will pay the out-of-pocket expenses incurred by AMETEK
in connection with the Merger and the Spin-Off if the Merger Agreement
terminates pursuant to clause (d)(i) above.
 
FEES AND EXPENSES
 
  Except as set forth above and subject to the Distribution Agreement, whether
or not the Merger is consummated, all costs and expenses incurred in connection
with the Merger Agreement and the transactions contemplated thereby will be
paid by the party incurring such expenses; provided, however, that AMETEK and
Culligan will each pay one-half of the printing, mailing and filing costs
incurred in connection with the Culligan Registration Statement, the New Ametek
Information Statement and this Joint Proxy Statement/Prospectus. The
Distribution Agreement provides that the maximum amount of costs and expenses
for which Culligan shall be liable shall not exceed $1,500,000 in the
aggregate.
   
AMENDMENT; WAIVER     
   
  The Merger Agreement may be amended by the parties thereto, by action taken
or authorized by their respective Boards of Directors, at any time before or
after approval of the matters presented in connection with the Merger by the
stockholders of AMETEK but, after any such approval, no amendment will be made
which by law requires further approval by such stockholders unless such further
approval has been obtained. Any amendment or waiver determined by the AMETEK
Board to be material will be subject to further approval of the stockholders.
The Merger Agreement may not be amended except by an instrument in writing
signed on behalf of each of the parties thereto. At any time prior to the
Effective Time, the parties to the Merger Agreement, by actions taken or
authorized by their respective Boards of Directors, may to the extent legally
allowed waive compliance with any of the agreements or conditions contained in
the Merger Agreement. Any such waiver will only be valid if set forth in a
written instrument signed by the party waiving any such agreement or condition.
    
INTEREST OF CERTAIN PERSONS IN THE TRANSACTION
 
  In considering the recommendation of the AMETEK Board, stockholders of AMETEK
should be aware that certain members of management of AMETEK and the AMETEK
Board may have certain interests in the Spin-Off and the Merger that are in
addition to the interests of stockholders generally.
 
  Ownership of AMETEK Common Stock. Certain directors and executive officers of
AMETEK beneficially own AMETEK Common Stock as described in "INFORMATION AS TO
NOMINEES FOR ELECTION OF DIRECTORS--Stock Ownership" and "EXECUTIVE
COMPENSATION--Stock Options and Stock Appreciation Rights." Following the
Merger, it is contemplated that a designee of American Securities, L.P., an
affiliate of AMETEK, will be nominated to the Culligan Board.
 
  Exchange of AMETEK Options. Each AMETEK Option held by a director or an
executive officer of AMETEK and employees of AMETEK, other than Water
Filtration Business Employees, will be exchanged for an option to purchase New
Ametek Common Stock. See "THE SPIN-OFF--Terms of the Distribution Agreement--
Employees and Employee Benefit Plans."
 
ACCOUNTING TREATMENT
 
  The Merger will be accounted for by Culligan under the purchase method of
accounting in accordance with GAAP, whereby the purchase price will be
allocated based on the fair value of the assets acquired and the liabilities
assumed. Such allocations will be based upon valuations that have not been
finalized. The excess of such purchase price over the amounts so allocated will
be recorded as goodwill. New Ametek will account for the transaction as a spin-
off of the Water Filtration Business, which will be reflected as a discontinued
operation in New Ametek's consolidated financial statements.

RESALES OF CULLIGAN COMMON STOCK ISSUED IN THE MERGER; AFFILIATES
 
  The Culligan Common Stock to be issued to AMETEK stockholders in connection
with the Merger will be freely transferable under the Securities Act, except
for shares issued to any person who may be deemed an "affiliate" of AMETEK
within the meaning of Rule 145 under the Securities Act. Persons who may be
deemed to be affiliates of AMETEK generally include individuals or entities
that control, are controlled by, or are under common control with, AMETEK, and
may include the directors and principal executive officers of AMETEK as well
as any principal stockholder of AMETEK.
 
NO APPRAISAL RIGHTS
 
  Holders of AMETEK Common Stock will not have the right to elect to have the
fair value of their shares of AMETEK Common Stock judicially appraised and
paid to them in cash in connection with the Spin-Off or the Merger. Under
Section 262 of the DGCL, appraisal rights are not available to the
stockholders of a corporation that is a party to a merger if the corporation's
stock is listed on a national securities exchange, as are the shares of AMETEK
Common Stock, if the consideration to be received by such stockholders in the
merger consists of shares of the capital stock of a corporation that is listed
on a national securities exchange, as are the shares of Culligan Common Stock.
 
DELIVERY OF SHARES TO STOCKHOLDERS
 
  AMETEK will effect the Spin-Off by delivery of certificates for shares of
New Ametek Common Stock to the Distribution Agent for delivery to the holders
of record of AMETEK Common Stock on the Spin-Off Record Date without any
further action by such holders.
 
  In order to receive the consideration to which the AMETEK stockholders will
be entitled to as a result of the Merger, each holder of AMETEK Common Stock
as of the Effective Time will be required to surrender their Certificates to
the Exchange Agent. See "--Conversion of AMETEK Common Stock--Exchange of
Certificates."

                                 THE SPIN-OFF
 
  This section of the Joint Proxy Statement/Prospectus describes certain
aspects of the proposed Contributions and the Spin-Off. To the extent that
they relate to the Distribution Documents, the following descriptions do not
purport to be complete and are qualified in their entirety by reference to the
Distribution Documents, which are included in Appendices B and D to this Joint
Proxy Statement/Prospectus and incorporated herein by reference. Certain
capitalized terms used herein and not defined have the meaning ascribed to
them in the Distribution Documents. ALL STOCKHOLDERS ARE URGED TO READ THE
DISTRIBUTION AGREEMENT, THE TAX ALLOCATION AGREEMENT, THE TRANSITION SERVICES
AGREEMENT, THE INDEMNIFICATION AGREEMENT AND THE TRADEMARK AGREEMENT IN THEIR
ENTIRETY. In addition, the holders of AMETEK Common Stock are urged to read in
its entirety the New Ametek Information Statement which is included as
Appendix E hereto.
 
BACKGROUND OF THE SPIN-OFF
   
  Because the Water Filtration Business is the only business of AMETEK that
Culligan wishes to acquire, AMETEK and Culligan determined to effect the Spin-
Off, which is intended to be tax-free to AMETEK and the holders of AMETEK
Common Stock for Federal income tax purposes (except to the extent of cash
received for fractional shares). See "CERTAIN FEDERAL INCOME TAX
CONSEQUENCES." It is a condition to consummating the Contributions, the Spin-
Off and the Merger that the Private Letter Ruling (which has been issued) not
be revoked and/or that AMETEK and Culligan receive the Tax Opinions. The
Contributions followed by the Spin-Off will separate all of AMETEK's other
businesses from the Water Filtration Business and enable Culligan to acquire
only the Water Filtration Business in the Merger; the Spin-Off will leave all
of AMETEK's other businesses as a separate publicly held company (New Ametek),
owned by the existing holders of AMETEK Common Stock.     
 
  Although the Spin-Off will not be effected unless the Merger and the Spin-
Off are approved by AMETEK Stockholders and all other conditions precedent
have been satisfied or waived, the Spin-Off is separate from the Merger, and
the shares of New Ametek Common Stock to be received by holders of AMETEK
Common Stock in the Spin-Off do not constitute a part of the Merger
consideration.
 
TERMS OF THE DISTRIBUTION AGREEMENT
 
 The Contributions
 
  Contributions of Assets
 
  Prior to the Spin-Off, AMETEK will effect the Contributions, with the result
that New Ametek will own, directly or through subsidiaries, all of the assets
formerly owned by AMETEK or its subsidiaries, other than the Water Filtration
Business.
 
  Transfer of Liabilities
 
  At or prior to the time of the Spin-Off, New Ametek will assume all of the
liabilities of AMETEK, other than certain liabilities relating to the Water
Filtration Business and the Retained Debt (collectively, the "Assumed
Liabilities"). The Assumed Liabilities shall include the Notes issued pursuant
to the Indenture and all obligations arising under the Credit Agreement (as
defined below), subject to the retention by AMETEK of the Retained Debt. New
Ametek shall also assume liability for (i) uninsured health, dental and vision
benefits incurred by Water Filtration Business Employees prior to the time of
the Spin-Off but only if claims therefor have been submitted prior to the
Spin-Off, (ii) those benefits incurred by Water Filtration Business Employees
prior to the Spin-Off which are covered by insurance policies assigned to and
assumed by New Ametek, (iii) all liability relating to or arising out of the
defined benefit pension plans maintained by AMETEK, other than the Water
Filtration Business Hourly Pension Plan, and (iv) all liability relating to or
arising out of the New Ametek Employees 401(k) Plan maintained by AMETEK.
 
                                      55
<PAGE>
 
  In August 1995, AMETEK entered into a $195,000,000 revolving credit
agreement (the "Credit Agreement") with a group of banks (the "Bank Group"),
led by The Chase Manhattan Bank, N.A., as administrative agent ("Chase"). In
connection with the Spin-Off, the Bank Group has entered into an amendment to
the Credit Agreement (the "Amendment") which, among other things, permits the
Credit Agreement to be assigned to and assumed by New Ametek. This assignment
and assumption shall occur immediately prior to completion of the Spin-Off.
The Amendment also contemplates that, prior to the Spin-Off, $25 million of
the outstanding principal amount under the Credit Agreement will be replaced
by separate loans from one or more members of the Bank Group and that such
separate loans will, after the Spin-Off, be retained by AMETEK as the Retained
Debt. The Amendment also provides some additional relief under certain of the
covenants contained in the Credit Agreement.
 
  AMETEK will retain certain liabilities relating to the Water Filtration
Business and the Retained Debt (the "Retained Liabilities").
 
  Certain Further Contributions
 
  If, after the time of the Spin-Off, either New Ametek or AMETEK holds assets
which by the terms of the Distribution Agreement or the Merger Agreement were
intended to be assigned and transferred to, or retained by, the other party,
such party will promptly assign and transfer or cause to be assigned and
transferred such assets to the other party.
 
 The Spin-Off
 
  Upon completion of the Contributions, the Spin-Off will be effected by the
distribution to each holder of record of AMETEK Common Stock as of the close
of business on the Spin-Off Record Date of certificates representing one share
of New Ametek Common Stock for every share of AMETEK Common Stock held by such
holder. As a result of the Spin-Off, the stockholders of record of AMETEK at
the close of business on the Spin-Off Record Date will own all of the
outstanding New Ametek Common Stock.
 
 Certain Covenants
 
  For five years after the Spin-Off, New Ametek will not, directly or
indirectly, (i) sell any products or render any services which are currently
being manufactured, sold or rendered by the Water Filtration Business, or (ii)
solicit any customer or supplier of the Water Filtration Business for any
purpose competitive with the Water Filtration Business; and for two years
after the Spin-Off, neither AMETEK nor New Ametek will, directly or
indirectly, solicit the employment of any employee of the other party and its
subsidiaries.
 
  Prior to the Spin-Off, AMETEK will transfer and assign to New Ametek all of
AMETEK's insurance policies other than (i) any policy which relates solely to
the Water Filtration Business and (ii) any policy that is not assignable
pursuant to its terms (a "Non-Assignable Policy"). If any policy is a Non-
Assignable Policy, it is the intent of AMETEK and New Ametek that New Ametek
receive the benefit of any coverage under any such policy, and that AMETEK
will keep such policy in effect during its remaining term and will refrain
from taking any actions (other than making a claim) which may affect New
Ametek's entitlement to the benefits of, or coverage under, such policy.
AMETEK and New Ametek also agree to cooperate with each other with respect to
the processing of any claims which are covered by any insurance policy in
existence prior to the time of the Spin-Off.
 
 Settlement of Intercompany Balances
 
  All amounts owing between the New Ametek entities and the Water Filtration
Business entities, other than amounts arising in the ordinary course of
business, will be deemed paid in full at or prior to the Spin-Off.
 
                                      56
<PAGE>
 
 Employees and Employee Benefit Plans
 
  Effective as of the Spin-Off Date, New Ametek will offer employment to all
employees of AMETEK, other than employees of the Water Filtration Business, on
the same terms and conditions as were in effect immediately prior to the Spin-
Off. Any such transfer of employment from AMETEK to New Ametek will not
constitute a termination or qualifying event under any severance policy.
 
  Also effective as of the Spin-Off Date, New Ametek will adopt (i) the AMETEK
company-wide 401(k) Plan, (ii) the AMETEK company-wide Employees' Retirement
Plan, a defined benefit pension plan covering all salaried employees hired
before January 1, 1997; (iii) all hourly defined benefit pension plans
sponsored by AMETEK, other than the separate pension plan covering only hourly
employees of the Water Filtration Business; and (iv) all severance, vacation,
medical, disability, life insurance, split-dollar and other welfare benefit
plans covering employees (and their spouses and dependents) of AMETEK, other
than any such plans or arrangements covering only employees of the Water
Filtration Business or the separable portion of such plans or arrangements
attributable to employees of the Water Filtration Business. As soon as
practicable on or after the Merger, New Ametek shall cause the AMETEK 401(k)
Plan to make a direct plan-to-plan transfer to Culligan's 401(k) Plan
consisting of the account balances of those participants who are employed in
the Water Filtration Business. The Employee's Retirement Plan, as adopted by
New Ametek, will retain the liability for all accrued pension benefits,
including the accrued benefits of participants employed in the Water
Filtration Business, as determined at the time of the Spin-Off, which benefits
will be payable upon the participants' subsequent retirement or termination of
employment from Culligan, or death or disability, as the case may be, as and
to the extent provided for by the Employees' Retirement Plan; provided, that
any such participant employed in the Water Filtration Business will continue
to be credited under the Employees' Retirement Plan for employment with AMETEK
and Culligan after the Spin-Off for purposes of vesting and eligibility for
early retirement, disability or pre-retirement death benefits (but not for the
purpose of determining the amount of the accrued benefit), and, further
provided, that any such participant's compensation shall continue to be
recomputed by taking into account compensation earned with AMETEK and Culligan
after the Spin-Off (but limited for Employees' Retirement Plan purposes to an
increase of 5%, per annum, of the 1996 compensation).
 
  Effective as of the Spin-Off Date, AMETEK shall continue to offer employment
to employees of the Water Filtration Business on the same terms and conditions
as in effect immediately prior thereto, and shall retain sponsorship of the
separate pension plan which covers only hourly employees of the Water
Filtration Business, and of all severance, vacation, medical, disability, life
insurance, split-dollar and other welfare benefit plans covering only
employees (and their spouses and dependents) of employees of the Water
Filtration Business or the separable portion of such plans or arrangements
attributable to employees of the Water Filtration Business.
 
 Stock Option and Stock Incentive Plans
 
  Prior to the Spin-Off, New Ametek will adopt one or more stock option, stock
incentive or similar plans for its employees and directors. Effective as of
the Spin-Off Date, all outstanding options to purchase the AMETEK Common Stock
which are held by employees, other than the employees of the Water Filtration
Business, whether or not such options are currently exercisable, will be
assumed by New Ametek and shall be exercisable upon the same terms and
conditions as in effect immediately prior thereto; provided, however, that
each such option shall cease to be exercisable with respect to the AMETEK
Common Stock and shall become exercisable for a whole number of shares of New
Ametek Common Stock and with an adjusted per share exercise price, determined
in accordance with Treasury Regulation (S)1.425-1 (whether the option is an
incentive stock option on a nonqualified stock option) so as to preserve both
the aggregate market spread between the value of the shares of common stock
subject to the option and the exercise price of the option immediately before
the Spin-Off, and the per share ratio between the value of the common stock
and the exercise price immediately before the Spin-Off. All stock appreciation
rights granted with respect to AMETEK Common Stock held by employees, other
than employees of the Water Filtration Business, whether then exercisable,
shall similarly be assumed by New Ametek and shall be exercisable upon the
same terms and conditions as in effect immediately prior thereto, provided
that the stock appreciation rights shall be subject to adjustment in a manner
similar to the adjustments to the assumed stock options, as described in the
preceding sentence.
 
                                      57
<PAGE>
 
  AMETEK has amended those outstanding stock options which are held by
employees of the Water Filtration Business to provide that, for a period
beginning March 20, 1997 and ending three business days prior to the date of
the Spin-Off (the "Special Offer Period"), (i) such options are fully
exercisable (i.e., vested), (ii) each such option holder may, as an
alternative to exercise, surrender his or her options, in whole or in part,
and receive from AMETEK a cash amount equal to the market spread between the
aggregate average company share price (determined as the average closing
prices of AMETEK Common Stock for the ten trading days ending on the second
trading day immediately prior to the Effective Time) over the aggregate
exercise price, in lieu of exercising the underlying options and (iii) AMETEK
will pay any holder of an option which was granted as an incentive stock
option (within the meaning of Section 422 of the Code) who exercises or
surrenders his options for the cash spread during the Special Offer Period an
amount, in cash, equal to 20% of the taxable gain recognized from the exercise
or surrender. For any option holder who is employed by the Water Filtration
Business and does not exercise or surrender his options for cash during the
Special Offer Period, any such unexercised options shall, at the end of the
Special Offer Period, revert to the level of exercisability (i.e., vesting) as
is determined solely by the terms of the option and the length of the option
holder's service since the date of grant, and the right to surrender the
options for cash and the right of holders of options which were granted as
incentive stock options to receive the special 20% cash payment, as described
above, shall lapse, and, as of the Effective Time, such unexercised options
will be exchanged for Culligan Options to purchase, pursuant to the Culligan
Option Conversion Ratio, a number of shares of Culligan Common Stock.
Effective as of the Spin-Off Date, AMETEK shall retain (and shall not
contribute to New Ametek) cash in an amount equal to 60% of the market spread
of the unexercised options held by Water Filtration Business Employees.
 
 Conditions to the Spin-Off
 
  The obligations of AMETEK and New Ametek to consummate the Spin-Off and to
perform all other obligations set forth in the Distribution Agreement are
subject to the satisfaction or waiver of (i) all the conditions contained in
the Merger Agreement which relate to AMETEK or New Ametek, and (ii) the
condition that all authorizations, orders or approvals, or declarations or
filings with, or the expiration of waiting periods imposed by, any
governmental entity or other public or private entity the failure of which to
obtain would have a material adverse effect on AMETEK or New Ametek, will have
been filed, occurred, or been obtained.
 
  The obligations of AMETEK to consummate the Spin-Off and perform all other
obligations set forth in the Distribution Agreement are subject to the
satisfaction or waiver of the condition that New Ametek will have effected its
assumption of the Assumed Liabilities as contemplated by the Distribution
Agreement.
 
  The obligations of New Ametek to consummate the transactions contemplated by
the Distribution Agreement and to perform all other obligations set forth in
the Distribution Agreement are subject to the satisfaction or waiver of the
condition that AMETEK will have contributed to New Ametek the Contributed
Assets, as contemplated by the Distribution Agreement.
   
 Amendment; Waiver     
   
  The Distribution Agreement (including the Annexes, Schedules and exhibits
thereto) may be amended in writing by AMETEK or New Ametek at any time prior
to the time of the Spin-Off with the prior written consent of Culligan. At any
time prior to the Spin-Off, either AMETEK or New Ametek may waive in writing
compliance by the other with any of the agreements or conditions contained in
the Distribution Agreement with the prior consent of Culligan. Any amendment
or waiver determined to be material by the AMETEK Board will be subject to
further approval of the stockholders. The failure of any party to the
Distribution Agreement to assert any of its rights under or to enforce any
provision of the Distribution Agreement or otherwise will not constitute a
waiver of its rights under such provision or any other provision.     
 
TERMS OF THE TAX ALLOCATION AGREEMENT
 
  In connection with the Spin-Off and the Merger, AMETEK, New Ametek and
Culligan will enter into the Tax Allocation Agreement, which provides for the
allocation of all tax liabilities of AMETEK and its subsidiaries for taxable
periods before and after the Spin-Off. In general, under the Tax Allocation
Agreement, (i) New
 
                                      58
<PAGE>
 
Ametek will be liable for any tax liability attributable to the Water
Filtration Business for taxable periods (or portions thereof) ending on or
before the Spin-Off Date and any tax liability attributable to the assets and
businesses to be transferred to or held by New Ametek (i.e., all of the assets
and businesses other than the Water Filtration Business) for all taxable
periods and (ii) AMETEK will be liable for any tax liability attributable to
the Water Filtration Business for taxable periods (or portions thereof)
beginning after the Spin-Off Date.
   
  In addition, except as provided below, New Ametek will be liable for any tax
liability resulting from transfers of stock and/or assets undertaken in
connection with or to effect the Contributions, the Spin-Off or the Merger
("Restructuring Taxes") including, without limitation, any tax liability
imposed on AMETEK as a result of the Contributions failing to qualify as a
reorganization under Section 368 (a) (1) (D) of the Code or the Spin-Off
failing to qualify as a distribution under Section 355 of the Code. AMETEK and
Culligan will be liable for any Restructuring Taxes caused by an action
inconsistent with Culligan's representations made in connection with obtaining
the Private Letter Ruling and/or the Tax Opinions and which is taken by
Culligan prior to the Spin-Off or by Culligan or AMETEK during the two-year
period after the Spin-Off. Furthermore, in the event that AMETEK and New
Ametek would each be liable for taxes resulting from the Spin-Off and/or the
Merger (without regard for any action taken by the other party), AMETEK and
New Ametek shall each be liable for one-half of such taxes and shall indemnify
each other for any excess of such amount paid. Pursuant to the Distribution
Agreement, AMETEK and New Ametek shall share equally all taxes (and certain
other transaction costs) incurred in connection with the Contributions and all
transfer taxes imposed in connection with or as a result of the Merger
subject, in the case of AMETEK, to a limit of $1,500,000.     
 
TERMS OF THE TRANSITION SERVICES AGREEMENT
 
  In connection with the Spin-Off and the Merger, New Ametek and the Surviving
Corporation will enter into the Transition Services Agreement, which sets
forth the obligations of New Ametek to provide the Surviving Corporation with
certain transition services and support, including but not limited to, payroll
and benefits administration; administrative services related to employee
benefit plans; advertising and marketing services; fixed asset accounting;
vehicle fleet management; management information systems; treasury services;
risk management services; tax compliance information; access to a web site;
access to financial information for audited financial statements; access to
shared facilities; and such other services as may be requested from time to
time to assist in the transition, for a period of up to nine (9) months after
the date of the Transition Services Agreement. In consideration for such
transition services, the Surviving Corporation will pay to New Ametek a fee
based on New Ametek's fully burdened costs of providing such services, which
will be mutually agreed upon by New Ametek and the Surviving Corporation prior
to the time such transition services are provided.
 
TERMS OF THE INDEMNIFICATION AGREEMENT
 
  In connection with the Spin-Off and the Merger, AMETEK, New Ametek and
Culligan will enter into an Indemnification Agreement which sets forth each
party's rights and obligations with respect to indemnification for matters
relating to the Contributions, the Spin-Off and the Merger.
 
  The Indemnification Agreement will provide that except as otherwise
specifically provided in the Merger Agreement or any of the Distribution
Documents, New Ametek will indemnify, defend and hold harmless Culligan from
and against, and pay or reimburse Culligan for, all Indemnifiable Losses, as
incurred: (a) arising out of or resulting from (x) the Contributed Assets or
the Assumed Liabilities (including the failure by New Ametek or any subsidiary
or Affiliate of New Ametek to pay, perform or otherwise discharge such Assumed
Liabilities in accordance with their terms) whether such Indemnifiable Losses
arise out of or result from events, occurrences, actions, omissions, facts or
circumstances occurring, existing or asserted before, at or after the
Effective Time or (y) the conduct or operation of AMETEK's business (other
than the conduct and operation of the Water Filtration Business) prior to the
Effective Time; (b) arising out of or resulting from any untrue statement or
alleged untrue statement of a material fact contained in any of the
Registration Statements or in this Joint Proxy Statement/Prospectus, or any
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they
 
                                      59
<PAGE>
 
were made, not misleading; but only in each case with respect to information
provided by AMETEK relating to New Ametek or AMETEK contained in or omitted
from the Registration Statements or this Joint Proxy Statement/Prospectus; (c)
arising out of or resulting from the breach by New Ametek or any of its
subsidiaries of any agreement or covenant contained in the Merger Agreement or
any of the Distribution Documents which does not by its express terms expire
at the Effective Time or which is not by its express terms required to be
performed prior to the Effective Time; (d) arising out of or resulting from
any breach of or inaccuracy in any representation or warranty of AMETEK or New
Ametek contained in the Merger Agreement; (e) arising out of or resulting from
any actual or alleged violation of any law, rule or regulation of any
Governmental Entity by AMETEK or New Ametek or any of their subsidiaries or
any director, officer, employee or agent of AMETEK or New Ametek or any of
their subsidiaries (collectively, "Legal Matters") occurring or alleged to
have occurred at or prior to the Effective Time with respect to the New Ametek
Businesses; (f) relating to or arising from any claim that the execution,
delivery or performance by AMETEK or New Ametek of the Merger Agreement and
each Ancillary Agreement to which it is or will be a party or the consummation
of the transactions contemplated thereby results in a violation or breach of,
or constitutes a default or impermissible transfer under, or gives rise to any
right of termination, first refusal or consent under or gives rise to any
right of amendment, cancellation or acceleration of any material benefit
under, any Contract to which AMETEK or any of its subsidiaries is a party
prior to the Spin-Off; and (g) arising out of or relating to the handling,
use, storage, recycling, treatment, transport, Release or disposal of
Hazardous Substances by AMETEK, any of its subsidiaries, affiliates or
predecessors (including any prior owner of the Retained Realty (as defined
below)) or any third party engaged by any of them, prior to the Effective
Time: (x) at any former properties or facilities of AMETEK or any of its
subsidiaries, affiliates, or predecessors (including any prior owner of the
Retained Realty, including former properties or facilities relating to the
Retained Assets or the Water Filtration Business (but not including any real
property owned or leased by the Water Filtration Business, as of the Spin-Off
Date (the "Retained Realty")); (y) at the Retained Realty, but only to the
extent that the Indemnifiable Losses arise from activities or business
operations that preceded the activities or business operations of the Water
Filtration Business at the Retained Realty; and (z) at any site or location
other than the Retained Realty where such handling, use, storage, recycling,
treatment, transport, Release or disposal (or arranging for such activities by
third parties) was related to the activities or business operations of the
Retained Assets or the Water Filtration Business (provided that this clause
(z) shall not cover any migration of a Release from the Retained Realty).
 
  The Indemnification Agreement will further provide that except as otherwise
specifically provided in the Merger Agreement or any of the Distribution
Documents, Culligan will indemnify, defend and hold harmless, or cause AMETEK
to indemnify, defend and hold harmless New Ametek from and against, and pay or
reimburse New Ametek for, all Indemnifiable Losses, as incurred: (a) arising
out of or resulting from (x) the Water Filtration Business or the Retained
Liabilities (including the failure by Culligan or any of its subsidiaries to
pay, perform or otherwise discharge such Retained Liabilities in accordance
with their terms) whether such Indemnifiable Losses arise out of or result
from events, occurrences, actions, omissions, facts or circumstances
occurring, existing or asserted before, at or after the Effective Time or (y)
the conduct or operation of the Water Filtration Business following the
Effective Time (other than any such conduct or operation which would give rise
to a right to indemnification by the Parent Indemnitees under the
Indemnification Agreement); (b) arising out of or resulting from any untrue
statement or alleged untrue statement of a material fact contained in any of
the Registration Statements or in this Joint Proxy Statement/Prospectus, or
any omission or alleged omission to state therein a material fact required to
be stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading; but only in each
case with respect to information provided by Culligan relating to Culligan or
any of its subsidiaries (other than AMETEK and its subsidiaries) contained in
or omitted from any of the Registration Statements or this Joint Proxy
Statement/Prospectus; (c) arising out of or resulting from the breach by
Culligan or any of its subsidiaries of any agreement or covenant contained in
the Merger Agreement or any of the Distribution Documents which does not by
its express terms expire at the Effective Time or which is not by its express
terms required to be performed prior to the Effective Time; and (d) relating
to or arising from any claim that the execution, delivery or performance by
Culligan or Culligan Merger Sub of the Merger Agreement and each Ancillary
Agreement to which it is or will be a party or the consummation of the
transactions contemplated thereby results in a violation or breach of, or
constitutes a
 
                                      60
<PAGE>
 
default or impermissible transfer under, or gives rise to any right of
termination, first refusal or consent under or gives rise to any right of
amendment, cancellation or acceleration of any material benefit under, any
Contract to which Culligan or Culligan Merger Sub is a party prior to the
Spin-Off.
 
  The Indemnification Agreement will provide that with respect to
Indemnifiable Losses arising out of or resulting from any breach or inaccuracy
in any representation or warranty of AMETEK or New Ametek contained in the
Merger Agreement, New Ametek will not have any liability under the
Indemnification Agreement unless the aggregate of all Indemnifiable Losses for
which New Ametek would be liable under the Indemnification Agreement exceeds
on a cumulative pre-tax basis an amount equal to $800,000 (the "Basket
Amount"); provided, that, once the Basket Amount is exceeded, New Ametek will
only pay Indemnifiable Losses in excess of such Basket Amount. Notwithstanding
the foregoing, New Ametek's liability for Indemnifiable Losses arising out of
or resulting from any breach or inaccuracy in any representation or warranty
of AMETEK or New Ametek contained in the Merger Agreement is limited (i) in
the aggregate to $25,000,000 and (ii) to only those Indemnifiable Losses for
which New Ametek has received written notice of on or prior to eighteen months
from the Closing Date.
 
TERMS OF THE TRADEMARK AGREEMENT
 
  Following the time of the Spin-Off, New Ametek will have the sole and
exclusive ownership of and right to use all of the names, trademarks, trade
names and other proprietary rights of AMETEK (collectively, the "Intellectual
Property"), including all rights to the "Ametek" name other than the
intellectual property relating primarily to the Water Filtration Business.
Pursuant to the Trademark Agreement between AMETEK and New AMETEK, AMETEK will
retain the right to use, for a period of five years, the "Ametek" trade name
and any AMETEK trademarks, service marks or logos which use the word "Ametek"
and are currently in use by the Water Filtration Business (collectively, the
"Marks"). In addition, for the three successive one-year terms following such
five year period, New Ametek will grant to AMETEK, pursuant to the Trademark
Agreement, an exclusive worldwide license to the Marks at a royalty rate of
$1,000,000 per year. AMETEK (which following the Merger will have changed its
name to Culligan Water Company, Inc.) is prohibited, however, from using the
"Ametek" mark alone or in connection with other terms as part of a corporate
name. The Trademark Agreement also provides for usual and customary
provisions, including quality control, audit and marking provisions.

                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
  The following is a summary of certain Federal income tax consequences of the
Contributions, the Spin-Off and the Merger. This summary is based upon the
Code, Treasury regulations promulgated thereunder, and judicial and
administrative interpretations thereof, all as in effect on the date hereof,
and which are subject to changes occurring after such date, possibly with
retroactive effect. This summary is for general information only and does not
address the effects of any state, local or foreign tax laws. In addition, it
does not purport to address all of the tax consequences applicable to any
particular taxpayer or to taxpayers subject to special treatment under the
Code, including, without limitation, foreign holders, holders of AMETEK Common
Stock acquired pursuant to the exercise of employee stock options or otherwise
as compensation, insurance companies, tax-exempt organizations, financial
institutions, broker dealers or persons who do not hold the AMETEK Common Stock
as a capital asset. EACH HOLDER OF AMETEK COMMON STOCK IS URGED TO CONSULT HIS
OR HER TAX ADVISOR AS TO THE SPECIFIC TAX CONSEQUENCES TO HIM OR HER OF THE
SPIN-OFF AND THE MERGER, INCLUDING THE APPLICATION AND EFFECT OF STATE, LOCAL
AND FOREIGN INCOME AND OTHER TAX LAWS AND OF CHANGES IN APPLICABLE TAX LAWS.
   
  The Private Letter Ruling was issued on June 16, 1997. The Contributions, the
Spin-Off and the Merger will not be consummated unless the IRS shall have not
revoked the Private Letter Ruling substantially to the effect that, on the
basis of the facts, representations and assumptions existing at the Effective
Time: (i) the Contributions followed by the Spin-Off qualify as a tax-free
reorganization pursuant to Section 368(a)(1)(D) of the Code; (ii) the Spin-Off
qualifies as a tax-free distribution pursuant to Section 355(a) of the Code;
and (iii) the Merger qualifies as a tax-free reorganization pursuant to Section
368 (a)(1)(B) of the Code.     
   
  If the IRS revokes the Private Letter Ruling as to any one or more of the
three rulings described in the preceding paragraph (each, an "Omitted Ruling"),
this requirement will nevertheless be satisfied if, on or prior to the Closing
Date, AMETEK receives an opinion of Stroock & Stroock & Lavan LLP and Culligan
receives an opinion of Skadden, Arps, Slate, Meagher & Flom LLP (together, the
"Tax Opinions") to the same effect as each such Omitted Ruling. Each such Tax
Opinion, if any, would be based upon certain qualifications and assumptions as
noted therein and upon certain representations of AMETEK, New Ametek and
Culligan. It would represent such counsel's best legal judgment and would not
be binding on the IRS or the courts. There can be no assurance that the IRS or
the courts would not take one or more contrary positions to those expressed in
the Tax Opinions.     
 
  The Contributions, the Spin-Off and the Merger will also not be consummated
unless there shall be no proposed legislation introduced in bill form and
pending action in Congress which, if enacted into law, would have the effect of
amending the Code so as to alter in any materially adverse respect any of the
Federal income tax consequences described in the Private Letter Ruling (and/or
the Tax Opinions) in respect of the Contributions, Spin-Off or Merger. On April
17, 1997, Senate Finance Committee Chairman William V. Roth Jr., Senate Finance
Committee ranking Democrat Daniel Patrick Moynihan and House Ways and Means
Committee Chairman Bill Archer introduced legislation (the "Proposed
Legislation") that if applicable to the Spin-Off and Merger would cause the
Spin-Off to be taxable to New Ametek. The Proposed Legislation would not apply
to any distribution after April 16, 1997 if the distribution is (i) made
pursuant to a written agreement which was (subject to customary conditions)
binding on April 16, 1997 and at all times thereafter, (ii) described in a
ruling request submitted to the IRS on or before April 16, 1997, or (iii)
described on or before such date in a public announcement or in a filing with
the Commission required solely by reason of the distribution (the "Transitional
Relief"). Since the Spin-Off and Merger would satisfy one or more of the
requirements for Transitional Relief, the Proposed Legislation, if enacted in
its present form, would not be applicable to the transactions. However, there
can be no assurance that the Proposed Legislation would be enacted in its
present form or that other legislation, materially adverse to the
Contributions, the Spin-Off or the Merger and with different effective dates
and/or transitional relief, would not be introduced or enacted after the date
hereof. The introduction or enactment of legislation differing from the
Proposed Legislation could delay or prevent consummation of the Contributions,
the Spin-Off and the Merger.

CONSEQUENCES OF THE CONTRIBUTIONS AND THE SPIN-OFF
 
  Based upon the Private Letter Ruling (and/or the Tax Opinions), the
following is a summary of the anticipated Federal income tax consequences of
the Contributions and the Spin-Off:
 
    1. No gain or loss will be recognized by (and no amount will be included
  in the income of) holders of AMETEK Common Stock on their receipt of New
  Ametek Common Stock in the Spin-Off.
 
    2. Following the Spin-Off, the aggregate tax basis of the AMETEK Common
  Stock and the New Ametek Common Stock in the hands of the holders of AMETEK
  Common Stock will equal the tax basis of the AMETEK Common Stock held
  immediately before the Spin-Off, allocated in proportion to the fair market
  value of each on the Spin-Off Date.
 
    3. The holding period of the New Ametek Common Stock received by the
  holders of AMETEK Common Stock will include the holding period of the
  AMETEK Common Stock on which the Spin-Off was made, provided such AMETEK
  Common Stock is held as a capital asset on the Spin-Off Date.
 
    4. No gain or loss will be recognized by AMETEK or New Ametek as a result
  of the Contributions or the Spin-Off.
 
  If the Contributions and the Spin-Off did not qualify for tax-free treatment
under Code Sections 368(a)(1)(D) and 355, then for Federal income tax purposes
(i) AMETEK would be required to recognize gain on the Spin-Off to the extent
that the fair market value of the shares of New Ametek Common Stock
distributed in the Spin-Off exceeded AMETEK's tax basis of such shares and
(ii) each holder of AMETEK Common Stock would be required to recognize
dividend income in an amount equal to the fair market value of the shares of
New Ametek Common Stock received in the Spin-Off, up to such stockholder's
allocable share of AMETEK's current and accumulated earnings and profits
(which would include the amount of gain referred to in clause (i) above).
 
CONSEQUENCES OF THE MERGER
 
  Based upon the Private Letter Ruling (and/or the Tax Opinions), the
following is a summary of the anticipated Federal income tax consequences of
the Merger:
 
    1. No gain or loss will be recognized by holders of AMETEK Common Stock
  whose shares of AMETEK Common Stock are exchanged solely for Culligan
  Common Stock pursuant to the Merger Agreement (except with respect to cash
  received by such holders of AMETEK Common Stock in lieu of fractional
  shares of Culligan Stock). An AMETEK stockholder who receives cash in lieu
  of fractional shares of Culligan Common Stock will recognize capital gain
  or loss in an amount equal to the difference between the cash so received
  and the portion of the tax basis in AMETEK Common Stock (as determined
  immediately following the Spin-Off) that is allocable to such fractional
  share. Such capital gain or loss will be long-term capital gain or loss,
  provided such fractional shares would have been held by such stockholder as
  a capital asset immediately prior to the Merger.
 
    2. The tax basis of the Culligan Common Stock received (or, in the case
  of fractional shares, deemed received) by holders of AMETEK Common Stock
  who exchange their AMETEK Common Stock solely for Culligan Common Stock in
  the Merger will be the same as the aggregate tax basis of the AMETEK Common
  Stock (as determined immediately following the Spin-Off) surrendered in
  exchange therefor.
 
    3. The holding period for the shares of Culligan Common Stock received in
  the Merger will include the period during which the shares of the AMETEK
  Common Stock surrendered in exchange therefor were held, provided that such
  shares of AMETEK Common Stock were held as a capital asset immediately
  prior to the Merger.
 
    4. No gain or loss will be recognized by AMETEK, Culligan Merger Sub or
  Culligan as a result of the Merger.
 
  If the Merger did not qualify for tax-free treatment as a reorganization
under Code Section 368(a)(1)(B), each holder of AMETEK Common Stock would
recognize gain or loss equal to the difference between the fair market value
of the Culligan Common Stock received and such holder's tax basis of the
shares of AMETEK Common Stock surrendered. Failure of the Merger to qualify as
a tax-free reorganization could jeopardize the tax-free treatment of the
Contributions and the Spin-Off under Code Sections 355 and 368(a)(1)(D).

              CULLIGAN UNAUDITED PRO FORMA FINANCIAL INFORMATION
   
  The following unaudited condensed pro forma combined statement of operations
for the fiscal year ended January 31, 1997 and for the three month period
ended April 30, 1997 give effect to the Merger as if it occurred on February
1, 1996. The accompanying unaudited condensed pro forma combined balance sheet
as of April 30, 1997 gives effect to the Merger as if it occurred on April 30,
1997.     
   
  The unaudited pro forma financial information of Culligan is presented for
illustrative purposes only and is not necessarily indicative of the combined
results of operation or financial position of Culligan if the Merger had
occurred on the assumed dates, nor is it necessarily indicative of the future
results of operations or financial position of Culligan. The unaudited pro
forma financial information is based on the historical consolidated financial
statements of Culligan for the year ended January 31, 1997 and for the three
month period ended April 30, 1997 and the Water Filtration Business for the
year ended December 31, 1996 and the three month period ended March 31, 1997
and should be read in conjunction with such historical financial information
and the notes thereto, which appear elsewhere herein and in the Culligan 10-K
and the Form 10-Q which are incorporated herein by reference. The selected
historical financial information for Culligan for the three month periods
ended April 30, 1996 and April 30, 1997 is derived from the unaudited
financial statements of Culligan and should be read in conjunction with
Culligan's quarterly report filed on Form 10-Q for the quarter ended April 30,
1997. In the opinion of Culligan's management, the summary consolidated
financial information for the three months ended April 30, 1996 and 1997
include all adjustments necessary to present fairly the information set forth
therein. Results of operations for the interim periods may not be indicative
of results for the full year. See "AVAILABLE INFORMATION" and "INCORPORATION
OF CERTAIN INFORMATION BY REFERENCE."     
 
  The pro forma adjustments applied in the unaudited pro forma financial
information reflect the Merger as a purchase. Under the purchase method of
accounting, the purchase cost will be allocated to acquired assets and
liabilities based on their fair relative values as of the Closing Date with
the excess of the purchase cost over fair value allocated to goodwill. Such
allocations are based on valuations and other studies that are not yet
complete. Accordingly, the final allocations will be different from those
reflected. However, based on current information, Culligan does not presently
expect the final allocations to differ materially from the amounts presented.

     NOTES TO CULLIGAN UNAUDITED CONDENSED PRO FORMA COMBINED STATEMENT OF
                                  OPERATIONS
                            (DOLLARS IN THOUSANDS)
 
(a) The Water Filtration Business statement of operations includes revenues
    and expenses derived from AMETEK's historical cost financial accounts. The
    associated revenues and expenses are either directly attributable to the
    Water Filtration Business or have been allocated to the Water Filtration
    Business based upon methods considered reasonable by AMETEK's management.
    The statement of operations of the Water Filtration Business were prepared
    in contemplation of the Merger.
 
(b) The pro forma adjustments do not reflect any operating efficiencies or
    cost savings that may result from the merged business. Also, a final
    determination of the required purchase accounting adjustments has not been
    made, and the earnings results will vary from those pro forma earnings
    shown based on the final adjustments.
 
(c) To eliminate November and December 1995 sales of $827 and cost of goods
    sold of $359 and selling, general and administrative expenses of $367
    related to APIC International S.A., a wholly owned subsidiary of the Water
    Filtration Business, that were included in the Water Filtration Business
    results for the year ended December 31, 1996.
   
(d) To reclassify research and development expenses of $618 and $160 included
    in the costs of goods sold of the Water Filtration Business to selling,
    general and administrative expenses for the year ended December 31, 1996
    and the three months ended March 31, 1997, respectively. These expenses
    are reclassed to selling, general and administrative expenses in order to
    present the statement of operations of the Water Filtration Business on a
    basis consistent with Culligan.     
   
(e) To reclassify depreciation expense of the Water Filtration Business to
    cost of goods sold by $1,856 and $505; and selling, general and
    administrative expenses by $63 and $22 for the year ended December 31,
    1996 and the three months ended March 31, 1997, respectively, in order to
    present the statement of operations of the Water Filtration Business on a
    basis consistent with Culligan.     
   
(f) To capitalize tooling costs expensed by the Water Filtration Business, net
    of additional depreciation expense related to such capitalized amounts.
    The adjustment results in a net decrease of $45 and $239 to cost of goods
    sold of the Water Filtration Business for the year ended December 31, 1996
    and the three months ended March 31, 1997, respectively. The adjustment is
    necessary to present the statement of operations of the Water Filtration
    Business in accordance with the accounting policies that will be used
    after the Merger.     
   
(g) To record amortization expense of $2,966 and $741 for the year ended
    January 31, 1997 and the three months ended April 30, 1997, respectively,
    for goodwill resulting from the excess of the purchase price paid by
    Culligan over the sum of identifiable assets acquired and liabilities
    assumed. The amortization period for goodwill is 40 years. Amortization
    expense also includes $160 and $40 for the year ended January 31, 1997 and
    the three months ended April 30, 1997, respectively, for identifiable
    trademarks which are being amortized over 20 years. Also see Note (c) to
    the Pro Forma Condensed Balance Sheet.     
   
(h) To record interest expense of $1,609 and $391, reflecting one year's and
    three months', respectively, estimated interest expense for the debt of
    $25,000 assumed in the Merger. Also see Note (e) to the Culligan Unaudited
    Condensed Pro Forma Combined Balance Sheet.     
     
  The effect of a 1/8 percent change in the interest rate on the $25,000 debt
  assumed in the Merger would be approximately $31 for the year ended January
  31, 1997 and $8 for the three months ended April 30, 1997.     
 
(i) To record the tax effect (at 40%) of all pro forma adjustments except
    goodwill, which is not tax deductible.
 
(j) To adjust the shares of common stock outstanding to reflect the issuance
    of 3,466,667 shares of Culligan common stock as if the shares were issued
    on February 1, 1996. Also see Note (f) to the Culligan Unaudited Condensed
    Pro Forma Combined Balance Sheet.

     NOTES TO CULLIGAN UNAUDITED CONDENSED PRO FORMA COMBINED BALANCE SHEET
 
                 (DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)
   
(a) It is assumed that the historical valuation of the assets and liabilities
    of the Water Filtration Business approximates the new book basis for the
    merged business, based on the preliminary allocation of the purchase price
    using the purchase method of accounting. Also see Note (c) regarding the
    preliminary allocation of the purchase price.     
   
(b) The $752 adjustment to property, plant and equipment results from the
    capitalization of the Water Filtration Business's tooling costs to be
    consistent with the accounting policies of Culligan. These costs were
    previously expensed by the Water Filtration Business. Also see Note (c)
    regarding the preliminary allocation of the purchase price.     
   
(c) The intangible assets amount of $121,825 represents goodwill of $118,625
    and identifiable trademarks of $3,200. Goodwill represents the excess of
    the purchase price (see Note (f)) paid by Culligan over the sum of
    identifiable assets acquired less liabilities assumed. Under purchase
    accounting, the purchase cost will be allocated to acquired assets and
    liabilities based on their relative fair values at the acquisition date
    based on valuations and other studies which are not yet complete. The
    identifiable trademarks of $3,200 will be amortized over 20 years, the
    expected life of the assets. The difference has been allocated to goodwill
    which will be amortized over forty years. Such allocations are subject to
    final determination based on real estate, leasehold, identifiable
    trademarks and equipment, valuation studies and a review of the books,
    records and accounting policies of the Water Filtration Business. These
    studies are expected to be completed after the acquisition date but before
    the end of fiscal 1998. Accordingly, the final allocations will be
    different from the amount reflected herein. However, based on current
    information, management does not presently expect the final allocations to
    differ materially from the amounts presented.     
 
(d) To record a financial advisory fee of $1,163 to be paid in connection with
    the purchase.
 
(e) To record issuance of $25,000 of long-term debt in connection with the
    purchase (also see Note (f) below). It is assumed the $25,000 will be
    obtained through additional borrowings on the Culligan Credit Facility.
   
(f) To record the issuance of 3,466,667 shares of Culligan's common stock at
    $36.85 a share for the purchase of the Water Filtration Business. The
    number of shares is based on a purchase price of $155,000, less assumed
    debt of $25,000, divided by $37.50 (as provided in the Merger Agreement).
        
  The market price of the Culligan Common Stock used to prepare this pro
  forma adjustment is based on the average of the closing price of Culligan
  Common Stock for a period of five days, beginning two days before the
  Merger announcement and ending two days following the Merger announcement.
  The estimated total market value of the common stock of $127,747 has been
  reduced by $273 which is the estimated direct costs of registration. The
  net market value of the common stock of $127,474 plus the face value of the
  long-term debt described in Note (e) and the financial advisory fee of
  $1,163 described in Note (d) equals the aggregate Merger consideration of
  $153,637.
     
  The aggregate Merger consideration may increase for Culligan stock options
  issued in substitution for stock options to purchase AMETEK Common Stock
  held by Water Filtration Business Employees. Culligan does not expect,
  however, the number of potential options issued, if any, to be material.
  The final purchase price is also subject to adjustment based on adjusted
  net worth of the Water Filtration Business to be determined upon an audit
  of the closing balance sheet.     
 
(g) To eliminate the equity of the Water Filtration Business.

                                 THE COMPANIES
   
  A more detailed description of the business of Culligan is contained in the
Culligan 10-K incorporated herein by reference. See "AVAILABLE INFORMATION"
and "INCORPORATION OF CERTAIN INFORMATION BY REFERENCE."     
 
CULLIGAN
 
  Culligan serves the household and consumer market, including the bottled
water market, and the commercial and industrial markets, including PDS,
operate and maintain ("O&M"), build, own and operate and other markets,
offering a broad range of products and services. Culligan's product lines
include filtration devices, reverse osmosis systems, desalination facilities,
bottled water, water softeners, deionizers and ultrafiltration products.
Product sizes range from small devices for residential customers to large
multi-process systems that are custom engineered and manufactured for
industrial customers. Through its independent dealers, company-owned dealers
and international distributors, Culligan also offers a full line of
accessories, replacement parts and services. In addition, Culligan is a major
provider of PDS both domestically and internationally.
 
  Culligan conducts its activities in two principal areas: household and
consumer and commercial and industrial.
 
 Household and Consumer
 
  Culligan is the leading manufacturer and distributor of water purification
and treatment products to residential customers in the United States.
Culligan's domestic and international household and consumer products and
services address residential water problems, including the removal of lead,
cysts and other health-related contaminants, the elimination of chlorine and
unpleasant odors and tastes from water, and the softening of water by removing
minerals.
 
  Culligan, through its independent and Culligan-owned dealers, sells,
installs and services a broad range of filters, reverse osmosis units and
water softeners that address household water problems. Culligan's strong brand
recognition, popularized by its famous "Hey Culligan Man!"(R) commercials, as
well as its extensive dealer network, have combined to give Culligan a leading
position in the residential water treatment market.
 
  Culligan produces and sells mechanical filtration systems and point-of-use
filters in the household and consumer market designed to improve the quality
of drinking water. In 1988, Culligan became the first to receive certification
from the independent National Sanitation Foundation ("NSF") under NSF's
standard for residential reverse osmosis drinking water systems. Since that
time, Culligan has developed many proprietary reverse osmosis systems to
improve the quality of drinking water, including Culligan's latest model of
its Aqua-Cleer(R) Drinking Water System that utilizes the reverse osmosis
process to filter tap water three times before it comes out of the faucet.
 
  Culligan also offers a wide array of water softening and conditioning
equipment and products for household use. Household automatic softeners and
portable exchange conditioners have constituted a large portion of Culligan's
household business since its inception.
 
  In fiscal 1997, Culligan, through its newly-formed Consumer Markets
Division, launched a line of water filtration products for sale through
department stores and do-it-yourself outlets and entered into several
marketing partnerships for the co-branding of products with partners that are
expected to provide rapid channel access and recurring revenue from
replacement filter sales. The first products introduced by the division,
faucet mount filters, were shipped to department stores in the second quarter
of fiscal 1997. By the end of the year, the division had expanded its product
offerings with the introduction of three new Culligan(R) home water filtration
product lines designed for the "do-it-yourself" market, consisting of under-
counter systems, refrigerator water/ice maker filter systems and a sediment
and rust reduction whole house filtration system and had announced the
introduction of
 
                                      70
<PAGE>
 
   
a designer glass pitcher filtration system and two new monitored faucet mount
systems that are being rolled out to the high-end department store channels in
fiscal 1998. In fiscal 1997, Culligan also entered into a marketing
partnership with Health-o-meter, the parent of Mr. Coffee, for plastic pour
through pitchers and with a major appliance manufacturer to provide a
refrigerator water/ice maker filtration system as well as a long-term
corporate partnering agreement with Moen Incorporated to develop Moen(R)
products incorporating Culligan water filtration assemblies.     
 
  Through its Everpure subsidiary, Culligan also serves the residential market
by providing point-of-use filtration systems for homes and apartments as well
as recreational vehicles such as Winnebago, Fleetwood and Airstream products.
Everpure's filtration systems reduce or remove off-tastes, odors, chlorine,
dirt, rust, asbestos fibers and parasitic protozoan cysts from the water
supply.
 
  Utilizing its distribution network and product technology, Culligan entered
the bottled water market in 1987 by licensing the sale of five-gallon
containers of bottled water under the Culligan name. Because of growing
consumer concern over the quality of water and its health effects, the bottled
water market has grown substantially in recent years and is expected to
continue to expand. Culligan's licensed bottled water sales now rank fourth in
the five-gallon bottled water market in the United States with an annual
growth rate of approximately 21% in fiscal 1997 and is the only brand in the
five-gallon bottled water business with a nationwide distribution network.
 
  Bottled water under the Culligan name is produced at over 100 company-owned,
franchised or licensed bottling locations and sold through over 500 company-
owned and franchised dealers in the United States. Culligan receives royalty
payments from its licensed producers and dealers based on the volume of sales.
Culligan's dealers typically deliver the five-gallon bottles to a customer's
home of office on a route basis, and the customer rents the dispenser console.
The dealers also pick up the empty bottles which are then cleaned and refilled
at the bottling location. Culligan generally does not participate in any other
segment of the bottled water market.
 
 Commercial and Industrial
 
  Culligan designs, manufactures and, primarily through its distribution
network, sells, installs and services a wide range of products to solve the
complex water problems of its commercial and industrial customers. These
products include filtration systems, reverse osmosis units, water softeners,
desalination systems, deionizers and high quality ultrafiltration and
microfiltration products capable of producing ultrapure water. Culligan
believes that its dealer network provides it with a competitive advantage in
the commercial and industrial markets because the dealers are able to service
systems on a national and international basis.
 
  Commercial
 
  Commercial users require water treatment systems that remove dissolved
minerals, such as calcium, magnesium, iron or manganese, and health-related
contaminants from the available water supply and are capable of treating large
quantities of water on a cost effective basis. Culligan's commercial products
use technologies similar to its residential products, but afford greater
capacity, durability and effectiveness and allow customers increased
flexibility for customization. For example, Culligan's filters, deionizers and
softeners provide food and beverage manufacturers with consistently high
quality water enabling them to preserve uniformity of taste and appearance in
their products, reduce health-related contaminants and minimize equipment
maintenance costs.
 
  Other commercial enterprises such as airlines, hotels, restaurants, car
washes, laundromats, office buildings and apartment complexes use Culligan
products to condition, filter, deionize and otherwise treat large quantities
of water. Unique features of Culligan's commercial water softeners include
high quality Cullex(R) resins, the Dubl-Safe(TM) brine system and a full range
of system controls that minimize salt usage, such as Culligan's solid state
Aqua-Sensor(R) regeneration control.
 
                                      71
<PAGE>
 
  Through Everpure, Culligan supplies water filtration products to commercial
businesses which require consistently high quality water. Everpure is the
leading supplier of water filtration products to the food service industry.
Sales to the food service industry constituted approximately 75% of Everpure's
revenues in its last fiscal year. Everpure's line of food service water
filtration products includes systems for post-mix beverage dispensers, ice
machines, coffee makers, steamers and vending machines that are designed to
treat all levels of water contamination and to ensure that consumer products
such as coffee, soups or ice are of the highest quality. Everpure systems also
decrease maintenance costs and extend the life of water-using equipment by
removing dirt and other abrasive particles that can damage the internal
workings of such equipment.
 
  Everpure complements Culligan's other operations by providing a presence in
selected markets where the Culligan's dealer network does not generally
participate. Everpure products are used extensively in many major fast-food
restaurants, including McDonald's(R) Burger King(R) and Starbucks(R) as well
as convenience store chains around the world, including 7-Eleven(R) and
Circle-K(R). In 1979, Everpure received NSF certification for its filtration
cartridges, and today substantially all of the Everpure systems carry the
highest NSF rating for both aesthetic and health effects. Everpure's principal
family of filter cartridges uses its proprietary precoat filtration process
using unique MicroPure(R) filtering media. Everpure's filtration and
disinfection products are also used in the airline, marine, offshore oil and
military markets.
 
  Everpure operates in most western European countries and Japan. In recent
years, Everpure has expanded internationally by following its customers into
developing countries where the water supply is of questionable quality. Its
market outside the United States is primarily the food service industry,
including fast-food chains, restaurants and offices. Everpure's products are
sold directly to equipment manufacturers, fast-food chains and convenience
store chains as well as to individual locations by Everpure's licensed
distributors.
 
  Culligan's newly acquired Bruner operation designs and manufactures water
softeners, filters, deionizers, dealkalizers, demineralizers, degasifiers and
reverse osmosis systems in standard and custom design configurations for
commercial and industrial applications worldwide. Bruner products are sold
through an extensive network of sales representatives supported by sales and
service locations in the United States and internationally.
 
  Industrial
 
  Industrial companies also require the removal of dissolved minerals and
contaminants from water before the water can be used in manufacturing
processes. A typical treatment system for these applications will combine
multiple processes, including clarification, depth filtration, carbon
filtration, softening, reverse osmosis, deionization, submicron cartridge
filtration and ultraviolet light disinfection. Through Bruner, Culligan also
designs and manufactures systems for industrial large volume process water
users including packaged systems utilizing multi-cell filters to reduce or
remove turbidity, iron, hydrogen sulfide, color and other particulates from
the water supply. Its industrial operations are also supported internationally
by its recent acquisition of Dewplan Limited, one of the UK's leading
specialist design contractors for high-purity and ultra-high purity industrial
water treatment systems.
 
  Culligan's and Bruner's products and technologies are used to remove
dissolved minerals and contaminants from water in numerous industrial
applications, including manufacturing operations, laboratories, research, food
processing, chemical processing, pharmaceutical facilities and printing
plants. In addition, Culligan and its dealers have substantial experience in
configuring systems used by manufacturers of prescription and non-prescription
drugs. Culligan and Bruner ultrapure water systems are also used by
manufacturers of products such as integrated circuits and compact discs.
 
  PDS
 
  Culligan and its dealer network also provide PDS to commercial and
industrial customers in the United States and Europe. Culligan's network
includes over 380 outlets and approximately 250 regeneration facilities. In
this growing business, Culligan provides portable water deionization treatment
equipment that uses resins as the filtration medium to produce ultrapure
water. Resin is retrieved and transported by a dealer service
 
                                      72
<PAGE>
 
representative to a dealer's regeneration plant for chemical recharging when
it is exhausted. Unlike many permanent systems, PDS requires no chemical
handling or maintenance by the customer. PDS is a widely used technology among
industrial and commercial companies and provides Culligan and its dealer
network with a recurring source of revenues and the opportunity to market its
systems and other services to its existing PDS customers.
 
  Medical
 
  Medical-related products often require ultrapure water free from certain
minerals and contaminants to operate effectively. Culligan is a leading
manufacturer of reverse osmosis units and comprise an integral part of the
kidney dialysis equipment used by hospitals, hemodialysis centers and other
health service providers. Culligan's reverse osmosis unit is one of a limited
number of such units registered by the United States Food and Drug
Administration as a medical device approved for this purpose.
 
  Desalination
 
  Culligan has produced major desalination systems throughout the world.
Culligan has supplied Egypt with fourteen desalination plants along the Red
Sea and in the southern Sinai region and, in the Arab Emirate of Umm-Al
Quwayn, Culligan supplied a 9,000 cubic meter per day desalination plant to
serve the potable water needs of the 15,000 inhabitants. In addition, its
recently acquired Culligan-Enerserve operation builds, owns and operates
desalination and other water and wastewater treatment systems in the
Caribbean. Since its acquisition in July 1996, that operation has expanded
significantly, obtaining an additional contract with the government of the
island of St. Maarten that is expected to generate revenues of approximately
$25,000,000 over the five-year term to own and operate a recently completed
2.6 million gallon per day desalination facility to produce water for the
island's residents.
 
  Municipal
 
  Although historically the municipal market has not represented a large
portion of the Culligan industrial business, Culligan believes that with the
re-enactment of the Safe Drinking Water Act there is significant growth
potential in this market. Culligan, through the efforts of its technical and
sales personnel, designs and manufactures and, through its dealer network,
sells, installs and services equipment and plants to chlorinate and remove
contaminants from water supplies. In the United States, Culligan typically
provides surface water treatment systems for of small municipalities, mobile
home parks and other residential groups with populations under 3,300 people.
Culligan's Multi-Tech(R) filtration system is a low-cost, pre-engineered,
packaged plant that contains all the steps used in a conventional water
treatment plant, such as coagulation, flocculation, clarification, filtration
and disinfection. Culligan currently has in place in North America, Europe and
Middle East over 700 pre-engineered, packaged Multi-Tech(R) and similar non-
U.S. OFSY Omnifiltration(R) systems to help communities meet their needs for
clean water. In addition, Culligan's Bruner operation offers self-contained
Bruner packaged water treatment plants in the municipal market. The Bruner
plants are custom engineered to produce potable water from almost any surface
water source and typically provide automated controls programmed to regulate
rapid or "flash" mixing, flocculation, settling and gravity filtration.
 
  Through Culligan Operating Services, Culligan also provides O&M services for
water and wastewater treatment facilities for municipalities and other large
users primarily in Florida and elsewhere in the Southeastern United States.
 
 Dealer and Distribution Network
 
  Culligan believes that the size and scope of its dealer and distributor
network make it uniquely positioned in the water purification and treatment
industry. Today there are over 1,100 independent Culligan dealers and
distributors and 45 company-owned dealers who distribute and service Culligan
products throughout the United States, Canada and Western Europe as well as
other foreign markets. In addition, there are over 350 distributors and
authorized agents in the United States and Western Europe as well as in other
foreign markets that distribute water filtration products of Culligan's
Everpure subsidiary for the food service industry and other commercial
businesses. Culligan's newly-acquired Bruner operation has approximately 93
sales representatives that distribute its products in the United States and
internationally. Culligan believes that this diverse geographical distribution
network allows it to react rapidly to changing customer needs as well as to
market conditions.
 
                                      73
<PAGE>
 
  As part of its distribution system, Culligan currently owns 26 Culligan
dealers in North America which had total revenues of approximately $70.5
million in the last fiscal year. The company-owned dealers are primarily
located in major metropolitan markets. Such markets include the New York
City/New Jersey, Los Angeles, Chicago, Houston, San Diego and San Francisco
metropolitan areas. Since the beginning of 1997, the company-owned Dealer
division has made eleven acquisitions with aggregate revenues of over
$19,000,000. Such acquisitions include dealerships in Elkhart, Indiana,
Glendale, Riverside, Santa Ana and San Diego, California, and Waukegan,
Illinois; bottled water operations in Houston, Texas, Omaha, Nebraska, and San
Diego, California; and a portable deionization service business in Santa
Clara, California. In addition, since the beginning of fiscal 1997, Culligan's
international division has acquired seven dealerships having aggregate
annualized revenues of approximately $7,000,000. Such dealerships are located
in Bordeaux, Lorraine, Somme-Oise and Cote-Opale, France; Lausanne,
Switzerland; and Florence, Italy, and Eau Water Treatment Company, an
independent French company specializing in commercial applications and
technical service support. In addition, Culligan Operating Services has made
eight acquisitions of complementary operations since being acquired by
Culligan in January 1996.
 
  Culligan-owned dealer operations generally have a high percentage of
revenues which are derived from sources believed to be recurring in nature
(estimated to be approximately 70% of total company-owned dealer revenues),
such as servicing equipment, sales of replacement parts, filters and other
consumables, equipment rental and royalties. Culligan's dealer and
distribution network enables it to offer complete solutions to pre-use water
problems for residential, commercial and industrial customers through a
combination of testing, product selection, installation, monitoring and
service. Culligan is continuously upgrading and expanding its dealer network
coverage. Culligan also has utilized its dealer network and distributors to
introduce new product lines and enter new markets.
 
  Typically, a dealer's territory covers a local community or metropolitan
area and the dealer sells or rents a significant portion of its products to
residential users.
 
  The size of dealerships range from small local operations involving only a
few employees to large multiple site dealerships. Generally, approximately
one-half of a dealer's revenues are derived from rental and service income
from existing customers. Certain dealers, including many large dealers, are
capable of providing standard and special-order commercial and industrial
products and services. Culligan's laboratories in Northbrook, Illinois;
Barcelona, Spain; and Bologna, Italy test water samples for dealers to help
them to identify a customer's water treatment needs.
 
  Dealers generally purchase all their requirements for water treatment
products from Culligan. Culligan assigns each dealer a primary area of
geographic responsibility and generally expects the dealer to cover the needs
of customers in this area, although the dealer has no exclusive right to this
territory. Virtually all of the Culligan sales of household products in North
America have been made through the dealer network. Dealers purchase equipment
from Culligan for sale, rental or use in their portable exchange service
programs. In addition, Culligan receives royalties from the sale of bottled
water and certain supplies that bear the Culligan name.
 
  Culligan provides dealers with a variety of services, including training,
education and technical assistance. It offers the dealers management, sales
and service seminars at the time of start-up and throughout their careers.
Culligan also employs technical service engineers who travel throughout the
United States aiding dealers with water quality needs. One of the unique
advantages Culligan supplies to its dealers, as an aid in commercial and
industrial sales, is Culligan's proprietary CAAP(R) pc software.
 
  Commercial and industrial job specifications and proposals are supported by
application and technical engineers located in Northbrook, Illinois. In
addition, Culligan provides the dealers with significant marketing services
and support, including an extensive co-operative advertising program. A
finance subsidiary of Culligan provides intermediate-term loans to franchised
dealers for equipment placed on rental or lease.

and "INCORPORATION OF CERTAIN INFORMATION BY REFERENCE."     
   
  The present businesses of AMETEK are comprised of the activities New Ametek
will undertake after the Spin-Off and the Water Filtration Business.     
 
NEW AMETEK
 
  New Ametek was incorporated on May 8, 1986 and has been a wholly owned
subsidiary of AMETEK since August 1989. To date, New Ametek's business has
consisted entirely of manufacturing aerospace instrumentation. Prior to the
Spin-Off, AMETEK will transfer or cause to be transferred to New Ametek all of
its assets other than those which are part of the Water Filtration Business,
and New Ametek will assume all of AMETEK's liabilities, except for certain
liabilities relating to the Water Filtration Business and certain indebtedness
of AMETEK. The principal executive offices of New Ametek are located at
Station Square, Paoli, Pennsylvania 19301 and its telephone number is (610)
647-2121.
 
THE WATER FILTRATION BUSINESS
 
  The Water Filtration Business is currently comprised of an operating
division of AMETEK, the Plymouth Products Division, and three foreign
subsidiaries of AMETEK: Ametek Filters, Limited; APIC International S.A., and
AFIMO S.A.M. The Water Filtration Business is a leader engaged in the design,
manufacture and marketing of point-of-use filtration products for the
separation, clarification and purification of liquids, primarily water. The
Water Filtration Business's strategy is to be a leader in the global
residential water filtration market and has opportunistically pursued selected
specialty filtration markets.
 
  In May 1967, AMETEK acquired Plymouth Industrial Products, a plastic
injection molding company, and named it Plymouth Plastics Division. In 1972,
AMETEK purchased the present Sheboygan, Wisconsin plant site. As the
division's focus on water and fluid filtration products increased, the
division name was changed in May 1974 to Plymouth Products.
 
  In 1991, AMETEK acquired Ametek Filters, Limited, a manufacturer of
industrial filtration products, located in Billingham, U.K., providing a base
for expansion into European markets. The acquisition of APIC and AFIMO, a
French producer of filtration devices, in November 1995 added new markets,
products, technology, and complementary customers.
 
  The Water Filtration Business's manufacturing is vertically integrated at
two of its three manufacturing sites, where it employs proprietary and
patented processes to manufacture and assemble the major components of its
filtration units. The primary raw materials are carbon, various resins,
plastics, and metals. The Water Filtration Business has not experienced a
shortage of raw materials in the past three years and expects an adequate
supply of raw materials at competitive prices to be available from multiple
suppliers.
 
  The Water Filtration Business's products include fluid filtration cartridges
for consumer, commercial, and industrial customers in the United States and
over 100 other countries. It offers a broad line of point-of-use cartridge
filters, ranging from whole-house to countertop water filtration systems, as
well as special-purpose filter housings and replacement cartridges that
significantly improve the quality and taste of water. The Water Filtration
Business has been a leader in water filtration products and technology for
over 25 years. It is known worldwide for quality products sold with the
following recognized brand names: AMETEK, Kleen-Plus(R), American Plumber,
APIC and Fluid-O.
 
                                      75

  Point-of-use drinking water filters are designed to enhance taste and remove
specific items, including hazardous chemicals, bacteria, particles and heavy
metals. For example, the Water Filtration Business's countertop filter with a
chemical metal removal cartridge is designed to remove unpleasant taste and
odor, including chlorine, dissolved lead and mercury, 99.95% of disease-
causing Giardia and Cryptosporidium cysts; certain pesticides and chemicals;
sediment and sand particles as small as 0.5 microns (nominal). After
processing 400 gallons of water, this cartridge filter is removed from the
filter housing and replaced. Sales of replacement products are an important
source of recurring revenues. The residential point-of-use countertop water
filters are completely portable and fit most standard faucets with an aerator;
installation requires no tools other than pliers.
 
  Filter cartridges and housings also are used in such applications as
commercial food and beverage dispensing, and cosmetic, chemical production,
the electronics industry and medical applications. Other products include
under-sink, icemaker, pitcher, recreational vehicle, reverse osmosis and
whole-house water filters, each offering a range of features for specialized
and general applications.
 
  The Water Filtration Business's sales and marketing strategy focuses on
comprehensive programs to address a broad range of customer needs. These
include sales, marketing and promotional programs, product packaging and
display, and pricing programs.
   
  The Water Filtration Business's markets include residential, commercial, and
industrial segments. Distribution channels include major hardware chains,
national home centers, water treatment distributors and private label products
for original equipment manufacturers and mass merchandisers. The Water
Filtration Business also has a branded line of filters, housings, and
cartridges designed for residential and commercial installation by plumbing
professionals. The five largest customers accounted for 18% and 19% of the
Water Filtration Business's sales for the three month periods ended March 31,
1997 and in 1996, respectively, with the three largest customers, Home Depot,
Ace Hardware and Cotter & Co., accounting for 8.7%, 3.2% and 2.3%,
respectively, of the first quarter 1997 sales, and 6.7%, 3.9% and 3.3%,
respectively, of first quarter 1996 sales.     
 
  Driving the commercial market segment is an increasing global need for
consistent water product quality for such uses as food service, fountain
beverages, steam ovens, coffee and tea. Industrial markets cover a wide range
of applications where component products and systems are used.
 
  The Water Filtration Business continues to grow at a faster rate than the
general filtration market. The Water Filtration Business's global markets are
highly competitive, including many domestic and international companies. No
one company has a significant presence in all markets. The principal methods
of competition are new product development, product performance and quality,
innovation, and distribution. Technical, and after market service and products
are also important competitive advantages.
   
  At March 31, 1997, the Water Filtration Business employed 409 people, of
which 261 were covered by a union. The Water Filtration Business has four
operating plants in one state and three foreign countries. Of these
facilities, two are owned and two are leased. The owned properties consist of
12 acres in Sheboygan, Wisconsin, of which 259,000 square feet are under roof,
and four acres in Teeside, England, of which 29,000 square feet are under
roof. The leases on the leased properties expire over a range of years from
1997 to 2003, with renewal options for varying terms contained in the leases.
The Water Filtration Business's machinery, plants and offices are in
satisfactory operating condition and are adequate for their respective uses.

                     DESCRIPTION OF CULLIGAN CAPITAL STOCK
 
AUTHORIZED CAPITAL STOCK
   
  The authorized capital stock of Culligan consists of 60,000,000 shares of
Culligan Common Stock, and 2,000,000 shares of preferred stock, par value $.01
per share ("Culligan Preferred Stock"). As of June 13, 1997, there were
21,391,201 shares of Culligan Common Stock issued and outstanding. Although no
shares of Culligan Preferred Stock have been issued as the date hereof, an
aggregate of 300,000 shares have been reserved for issuance in connection with
Culligan's stockholder rights plan described below under "Culligan Stockholder
Rights Plan."     
 
COMMON STOCK
 
  The holders of Culligan Common Stock are entitled to one vote for each share
held of record on all matters submitted to a vote of Culligan stockholders.
Subject to preferences that may be applicable to any outstanding Culligan
Preferred Stock, holders of Culligan Common Stock are entitled to receive
ratably such dividends as may from time to time be declared by the Culligan
Board out of funds legally available therefor. In the event of a liquidation,
dissolution or winding up of Culligan, holders of Culligan Common Stock would
be entitled to share ratably in all assets of Culligan available for
distribution to holders of Culligan Common Stock remaining after payment of
liabilities and liquidation preference of any outstanding Culligan Preferred
Stock. Holders of Culligan Common Stock have no preemptive rights and have no
rights to convert their Culligan Common Stock into any other securities and
there are no redemption provisions with respect to such shares. All of the
outstanding shares of Culligan Common Stock are fully paid and nonassessable.
 
PREFERRED STOCK
 
  The Culligan Board has the authority to issue Culligan Preferred Stock in
one or more classes or series and to fix the designations, powers, preferences
and rights of the shares of each such class or series, including dividend
rates, conversion rights, voting rights, terms of redemption and liquidation
preferences and the number of shares constituting each such class or series,
without any further vote or action by Culligan stockholders. Although no
shares of Culligan Preferred Stock have been issued as of the date hereof, an
aggregate of 300,000 shares of junior participating preferred stock have been
reserved for issuance in connection with Culligan's stockholder rights plan
described below under "Culligan Stockholder Rights Plan." Culligan has no
other present plans to issue any shares of Culligan Preferred Stock.
 
TRANSFER AGENT AND REGISTRAR
 
  The Transfer Agent and Registrar for Culligan Common Stock is The First
National Bank of Boston.
 
CULLIGAN STOCKHOLDER RIGHTS PLAN
 
  On September 13, 1996, Culligan declared a dividend distribution of one
right (a "Culligan Right") for each outstanding share of Culligan Common Stock
to stockholders of record at the close of business on September 26, 1996 (the
"Rights Record Date"). Each Culligan Right entitles the registered holder to
purchase from Culligan one one-hundredth of a share of Series A Junior
Participating Preferred Stock, par value $0.01 per share (the "Series A
Preferred Stock"), at a purchase price of $78, subject to adjustment. The
description and terms of the Culligan Rights are set forth in a Rights
Agreement (the "Culligan Rights Agreement") between Culligan and The First
National Bank of Boston, as Culligan Rights Agent. Culligan Rights also attach
to all other shares of Culligan Common Stock, including the shares issuable in
the Merger, issued prior to the Distribution Date (as defined below) or the
earlier expiration of the Culligan Rights Agreement.
 
  Initially, the Culligan Rights will be attached to all Culligan Common Stock
certificates representing shares then outstanding, and no separate Culligan
Rights Certificates will be distributed. The Culligan Rights will separate
from Culligan Common Stock and a Distribution Date will occur upon the earlier
of (i) ten (10) business days following public announcement that a person or
group of affiliated or associated persons (an "Acquiring
 
                                      77
<PAGE>
 
Person") has acquired beneficial ownership of 15% or more of the outstanding
shares of Culligan Common Stock, other than an Exempted Person (the "Stock
Acquisition Date"), or (ii) ten (10) business days (or such later date as the
Culligan Board shall determine) following commencement of a tender offer or
exchange offer that would result in a person or group becoming an Acquiring
Person. "Exempted Person" indicates any person who was the beneficial owner,
on September 3, 1996, of 15% or more of the outstanding shares of Culligan
Common Stock and such person's affiliates and associates, provided that such
person, and such person's affiliates and associates, do not increase their
percentage ownership of Culligan Common Stock by more than five percentage
points over their percentage ownership on such date.
 
  Until the Distribution Date, (i) Culligan Rights will be evidenced by
Culligan Common Stock certificates and will be transferred with and only with
such Culligan Common Stock certificates, (ii) new Culligan Common Stock
certificates issued after the Record Date will contain a notation
incorporating the Culligan Rights Agreement by reference and (iii) the
surrender for transfer of any certificates for Culligan Common Stock
outstanding will also constitute the transfer of the Culligan Rights
associated with the Culligan Common Stock represented by such certificate.
Pursuant to the Culligan Rights Agreement, Culligan reserves the right to
require prior to the occurrence of a Triggering Event (as defined below) that,
upon any exercise of rights, a certain number of Culligan Rights be exercised
so that only whole shares of Series A Preferred Stock will be issued.
 
  Culligan Rights are not exercisable until the Distribution Date and will
expire at the close of business on September 13, 1997, unless earlier redeemed
or extended by Culligan as described below.
 
  As soon as practicable after the Distribution Date, Culligan Rights
Certificates will be mailed to holders of record of Culligan Common Stock as
of the close of business on the Distribution Date and, thereafter, the
separate Culligan Rights Certificates alone will represent the Culligan
Rights.
 
  In the event that a person becomes an Acquiring Person (except pursuant to
an offer for all outstanding shares of Culligan Common Stock that the
disinterested directors of Culligan determine not to be inadequate and to
otherwise be in the best interest of Culligan and its stockholders), each
holder of a Culligan Right will thereafter have the right to receive, upon
exercise, Culligan Common Stock (or, in certain circumstances, cash, property
or other securities of Culligan) having a value equal to two times the
exercise price of the Right. Notwithstanding any of the foregoing, following
the occurrence of the event set forth in this paragraph, all Culligan Rights
that are, or (under certain circumstances specified in the Culligan Rights
Agreement) were, beneficially owned by any Acquiring Person will be null and
void. However, Culligan Rights are not exercisable following the occurrence of
the event set forth above until such time as Culligan Rights are no longer
redeemable by Culligan as set forth below.
 
  For example, at an exercise price of $78 per Culligan Right, each Culligan
Right not owned by an Acquiring Person (or by certain related parties)
following an event set forth in the preceding paragraph would entitle its
holder to purchase $156 worth of Culligan Common Stock (or other
consideration, as noted above) for $78. Assuming that Culligan Common Stock
had a per share value of $39 at such time, the holder of each valid Culligan
Right would be entitled to purchase four shares of Culligan Common Stock for
$78.
 
  In the event that, at any time following the Stock Acquisition Date, (i)
Culligan is acquired in a merger or other business combination transaction
(other than a merger which follows an offer described in the second preceding
paragraph), or (ii) fifty percent (50%) or more of Culligan's assets, cash
flow or earning power is sold or transferred, each holder of a Culligan Right
(except Culligan Rights which previously have been voided as set forth above)
will thereafter have the right to receive, upon exercise, common stock of the
acquiring company having a value equal to two times the exercise price of the
Culligan Right. The events set forth in this paragraph and in the second
preceding paragraph are referred to as the "Triggering Events."
 
  At any time until ten (10) business days following the Stock Acquisition
Date, Culligan may redeem the Culligan Rights in whole, but not in part, at a
price of $.005 per Culligan Right (payable in cash, Culligan Common Stock or
other consideration deemed appropriate by the Culligan Board). Immediately
upon the action
 
                                      78
<PAGE>
 
of the Culligan Board ordering redemption of the Culligan Rights, the Culligan
Rights will terminate and the only right of the holders of Culligan Rights
will be to receive the $.005 redemption price.
 
  Until a Culligan Right is exercised, the holder thereof, as such, will have
no rights as a stockholder of Culligan, including, without limitation, the
right to vote or to receive dividends. While the distribution of Culligan
Rights will not be taxable to stockholders or to Culligan, stockholders may,
depending upon the circumstances, recognize taxable income in the event that
Culligan Rights become exercisable for Culligan Common Stock (or other
consideration) or for common stock of the acquiring company as set forth
above.
 
  Any of the provisions of the Culligan Rights Agreement may be amended by the
Culligan Board prior to the Distribution Date. After the Distribution Date,
the provisions of the Culligan Rights Agreement may be amended by the Culligan
Board in order to cure any ambiguity, to make changes which do not adversely
affect the interests of holders of Culligan Rights, or to shorten or lengthen
any time period under the Culligan Rights Agreement; provided, however, that
no amendment to lengthen a time period relating to when the Culligan Rights
may be redeemed may be made at such time as the Culligan Rights are not
redeemable.
 
  Culligan Rights have certain anti-takeover effects. Culligan Rights will
cause substantial dilution to a person or group that attempts to acquire
Culligan on terms not approved by the Culligan Board. The Culligan Rights
should not interfere with any merger or other business combination approved by
the Culligan Board since Culligan Rights may be redeemed by Culligan at any
time until ten (10) business days following the Stock Acquisition Date.

                     COMPARISON OF RIGHTS OF STOCKHOLDERS
 
  The rights of holders of AMETEK Common Stock are presently governed by
Delaware corporate law, the AMETEK Certificate and the AMETEK By-Laws. As a
result of the Merger, holders of AMETEK Common Stock will become stockholders
of Culligan, also a Delaware corporation. Accordingly, such holders' rights
will be governed by Delaware corporate law, the Culligan Certificate and the
Culligan By-Laws. Certain differences in the rights of stockholders arise from
distinctions between the AMETEK Certificate and the Culligan Certificate and
between the AMETEK By-Laws and the Culligan By-Laws. The following is a brief
description of the material differences. This description does not purport to
be a complete statement of all differences between the rights of the
stockholders of AMETEK and the stockholders of Culligan, and the
identification of specific differences is not meant to indicate that other
differences do not exist. The following description is qualified in its
entirety by reference to the AMETEK Certificate, the AMETEK By-Laws, the
Culligan Certificate and the Culligan By-Laws. For information on how to
obtain copies of any of these documents, see "AVAILABLE INFORMATION."
 
COMMON STOCK CLASSIFICATION
 
  AMETEK and Culligan have issued and outstanding just one class of shares of
common stock. Each holder of Culligan Common Stock and each holder of AMETEK
Common Stock has one vote for each share registered in such stockholder's
name. See "DESCRIPTION OF CULLIGAN CAPITAL STOCK."
 
DIRECTORS
 
  The AMETEK Certificate and AMETEK By-Laws provide that the AMETEK Board
shall consist of no fewer than 6 nor more than 12 directors, as determined by
the AMETEK Board or AMETEK's stockholders, and be elected for a one-year term
at the annual meeting of holders of AMETEK Common Stock. The AMETEK By-Laws
provide that the number of directors of AMETEK may be increased or decreased
by holders of AMETEK Common Stock at any annual or special meeting and may be
increased or decreased by the affirmative vote of not less than 75% of
directors then in office. The Culligan Certificate and Culligan By-Laws
provide that the Culligan Board shall consist of no fewer than 3 nor more than
15 members as determined by the Culligan Board, such number of directors to be
divided into three classes (Class I, Class II and Class III), each class
having a three-year term and consisting, as nearly as possible, of one-third
of the total number of directors. At each annual meeting of stockholders of
Culligan, successors to the class of directors whose terms expire will be
elected for a three-year term of office, with the three-year term of each
class of the directors expiring at successive annual meetings of the
stockholders, so that one class will be elected each year.
 
  The purpose of a classified board is to promote conditions of continuity and
stability in the composition of a board of directors and in the policies
formulated by a board of directors, by guaranteeing that in the ordinary
course at least two-thirds of the directors will at all times have had at
least one year's experience as directors of a corporation. However, for
similar reasons, a classified board may deter certain mergers, tender offers
or other takeover attempts which some or a majority of the holders of a
corporation's stock may deem to be in their best interest, since it would take
two annual meetings of stockholders to elect a majority of the board of
directors of such corporation. Similarly, a classified board structure would
delay stockholders who do not like the policies of a board of directors from
removing a majority of a board of directors at a single annual meeting.
 
  None of the AMETEK Certificate, the AMETEK By-Laws, the Culligan Certificate
or Culligan By-Laws provides for the removal of directors. Accordingly, the
removal of directors of both AMETEK and Culligan is governed by the DGCL,
which provides that any director or the entire board of directors may be
removed, with or without cause, by the holders of a majority of shares
entitled to vote for the election of directors, except (i) unless the
certificate of incorporation otherwise provides, in the case of a corporation
having a classified board, stockholders may effect such removal only for cause
and (ii) in the case of a corporation having cumulative
 
                                      80
<PAGE>
 
voting, if less than the entire board is to be removed, no director may be
removed without cause if the votes cast against his removal would be
sufficient to elect him if then cumulatively voted at an election of the
entire board of directors, or, if there are classes of directors, at an
election of the class of directors of which he is a part.
 
  The term "cause" is not defined in the DGCL. Consequently, any question
concerning the legal standard for "cause" would have to be judicially
determined.
 
ADVANCE NOTICE OF NOMINATIONS FOR THE ELECTION OF DIRECTORS AND STOCKHOLDERS
PROPOSALS
 
  The Culligan By-Laws establish an advance notice procedure for stockholders
to make nominations of candidates for election as directors, or bring other
business before an annual meeting of stockholders of Culligan (the
"Stockholder Notice Procedure"). The Stockholder Notice Procedure provides
that only persons who are nominated by, or at the direction of, the Culligan
Board, or by a stockholder who has given timely written notice to the
Secretary of Culligan prior to the meeting at which directors are to be
elected, will be eligible for election as directors of Culligan. The
Stockholder Notice Procedure provides that at an Annual Meeting only such
business may be conducted as has been specified in the notice of the meeting
given by or at the direction of the Culligan Board (or any duly authorized
committee thereof) or brought before the meeting by, or at the direction of,
the Culligan Board (or any duly authorized committee thereof) or by a
stockholder who has given timely written notice to the Secretary of Culligan
of such stockholder's intention to bring such business before such meeting.
 
  Under the Stockholder Notice Procedure, for notice of stockholder
nominations to be made or business to be conducted at an annual meeting to be
timely, such notice must be received by Culligan not less than sixty (60) days
nor more than ninety (90) days prior to the date of the annual meeting or, in
the event that less than seventy (70) days' notice or prior public disclosure
of the date of the Annual Meeting is given or made to stockholders, not later
than the close of business on the 10th day following the day on which such
notice was mailed or such public disclosure was made, whichever first occurs.
Under the Stockholder Notice Procedure, for notice of a stockholder nomination
to be made at a special meeting at which directors are to be elected to be
timely, such notice must be received by Culligan not later than the close of
business on the 10th day following the day on which such notice of the date of
the special meeting was mailed or public disclosure of the date of the special
meeting was made, whichever first occurs.
 
  In addition, under the Stockholder Notice Procedure, a stockholder's notice
to Culligan proposing to nominate a person for election as a director or
conduct certain business at an annual meeting must contain certain specified
information. If the Chairman of the Board of Directors of Culligan presiding
at a meeting determines that a person was not nominated, or other business was
not brought before the meeting, in accordance with the Stockholder Notice
Procedure, such person will not be eligible for election as a director, or
such business will not be conducted at such meeting, as the case may be.
 
  The AMETEK By-Laws do not contain a similar advance notice provision.
Accordingly, except as provided in Regulation 14A under the Exchange Act,
holders of AMETEK Common Stock are able to nominate candidates for election as
directors at stockholders' meetings or to submit proposals without advance
notice to AMETEK. Consequently, holders of AMETEK Common Stock can more easily
submit director nominees and other matters for stockholder consideration as
compared to Culligan stockholders.
 
ACTION BY WRITTEN CONSENT
 
  The Culligan By-Laws allow stockholders to take action without a meeting,
without prior notice and without a vote, upon the written consent of
stockholders having not less than the minimum number of votes that would be
necessary to authorize a proposed action at a meeting at which all shares
entitled to vote were present and voted. The AMETEK By-Laws permit holders of
AMETEK Common Stock to act by written consent without a meeting, provided that
such action must be authorized by unanimous written consent signed by all of
the holders of outstanding voting stock. However, under the DGCL, unless a
corporation's certificate of incorporation provides otherwise, stockholders
may take action without a meeting, without prior notice and without a vote,
 
                                      81
<PAGE>
 
upon the written consent of stockholders having not less than the minimum
number of votes that would be necessary to authorize the proposed action at a
meeting of which all shares entitled to vote were present and voted.
Accordingly, since the AMETEK Certificate does not provide for requirements
for action by written consent that are different than the DGCL, the DGCL
requirements outlined in the previous sentence would most likely control any
action by written consent taken by holders of AMETEK Common Stock.
 
MEETINGS OF STOCKHOLDERS
 
  The AMETEK By-Laws provide that a special meeting of the stockholders of
AMETEK may be called by the President of AMETEK. The President or Secretary of
AMETEK is required to call a special meeting whenever requested in writing to
do so by a majority of the AMETEK Board or by stockholders owning not less
than twenty percent of the shares of AMETEK then issued and outstanding and
entitled to vote at such meeting.
 
  The Culligan By-laws provide that a special meeting of the stockholders of
Culligan may be called by the Chairman, the President, any Vice President, the
Secretary or any Assistant Secretary of Culligan, and any such officer is
required to call a special meeting at the request in writing of a majority of
the Culligan Board.
 
AMENDMENT OF CERTIFICATE OF INCORPORATION
 
  Under the DGCL, a certificate of incorporation of a Delaware corporation may
be amended by approval of the amendment by the board of directors of such
corporation and the affirmative vote of the holders of a majority of the
outstanding shares of stock entitled to vote thereon unless the certificate of
incorporation prescribes a higher requirement. Neither the AMETEK Certificate
nor the Culligan Certificate prescribes a higher requirement.
 
AMENDMENT OF BY-LAWS
 
  The AMETEK By-Laws may be altered, amended or repealed or new by-laws may be
adopted by the stockholders of AMETEK or by the AMETEK Board at any regular
meeting of the stockholders or of the AMETEK Board or at any special meeting
of the stockholders of AMETEK or of the AMETEK Board if notice of such
alteration, amendment, repeal or adoption or new By-Laws be contained on the
notice of such special meeting and such amendment is approved by a majority of
the Directors of AMETEK or the affirmative vote of the holders of a majority
of outstanding shares of AMETEK Common Stock. The Culligan By-Laws may be
altered, amended or repealed, in whole or in part, or new by-laws may be
adopted by Culligan stockholders or by the Culligan Board, provided that
notice of such alteration, amendment, repeal or adoption of new By-Laws is
contained in the notice of such meeting of stockholders or the Culligan Board
and such amendments are approved by either a majority of the Directors of
Culligan or the affirmative vote of the holders of a majority of the
outstanding shares of Culligan Common Stock.
 
APPROVALS OF MERGERS AND ASSETS SALES
 
  Under the DGCL, unless required by its certificate of incorporation, no vote
of the stockholders of a constituent corporation surviving a merger is
necessary to authorize such merger if: (i) the agreement of merger does not
amend the certificate of incorporation of such constituent corporation; (ii)
each share of stock of such constituent corporation outstanding prior to such
merger is to be an identical outstanding or treasury share of the surviving
corporation after such merger; (iii) either no shares of common stock of the
surviving corporation and no shares, securities or obligations convertible
into such common stock are to be issued under such agreement of merger, or the
number of shares of common stock issued or so issuable does not exceed 20% of
the number thereof outstanding immediately prior to such merger; and (iv)
certain other conditions are satisfied. In addition, the DGCL provides that a
parent corporation that is the record holder of at least 90% of the
outstanding shares of each class of stock of a subsidiary may merge such
subsidiary into such parent corporation or other subsidiary owned by it
without the approval of such subsidiary's stockholders or board of directors.
Whenever the approval of the stockholders of a corporation is required for an
agreement of merger or consolidation or for a sale, lease
 
                                      82
<PAGE>
 
or exchange of all or substantially all of its assets, such agreement, sale,
lease or exchange must be approved by the affirmative vote of the holders of a
majority of outstanding shares of such corporation entitled to vote thereon.
 
  None of the AMETEK Certificate, the AMETEK By-Laws, the Culligan Certificate
or the Culligan By-Laws contains supermajority voting provisions relating to
the approval of business combinations by stockholders.
 
STATE ANTI-TAKEOVER STATUTES
 
  Section 203, a statutory provision restricting business combinations with
certain stockholders who acquire 15% or more of a Delaware corporation's
voting stock, is applicable to AMETEK but not to Culligan because the Culligan
Certificate provides that Section 203 shall not apply to Culligan. Section 203
prohibits certain "business combinations" transactions (defined broadly to
include mergers, consolidations, sales or other deposition of assets having an
aggregate value in excess of 10% of the consolidated assets of the
corporation, and certain transactions that would increase the interested
stockholder's proportionate share ownership in the corporation) between a
publicly held Delaware corporation and any "interested stockholder" for a
period of three years after the date on which the interested stockholder
became an interested stockholder unless (a) prior to that date the
corporation's board of directors approved either the proposed business
combination or the transaction which resulted in the interested stockholder
becoming an interested stockholder, (b) upon consummation of the transaction
which resulted in the interested stockholder becoming an interested
stockholder, the interested stockholder owned at least 85% of the voting stock
of the corporation outstanding at the time the transaction commenced,
excluding for purposes of determining the number of shares outstanding those
shares owned (i) by persons who are directors and also officers and (ii) by
employee stock plans in which employee participants do not have the right to
determine confidentially whether shares held subject to the plan will be
tendered in a tender or exchange offer, or (c) on or subsequent to such date
the business combination is approved by the corporation's board of directors
and authorized at an annual or special meeting of stockholders, and not by
written consent, by the affirmative vote of at least two-thirds of the
outstanding voting stock which is not owned by the interested stockholders.
 
  Section 203 would not prevent the holders of a controlling interest from
exercising control over AMETEK or Culligan and would not prevent a hostile
takeover or hostile acquisition of control of AMETEK or Culligan. Section 203
may, however, discourage or make more difficult a hostile takeover or
acquisition of control.
 
LIMITATION OF LIABILITY
 
  Section 102(b)(7) of the DGCL allows a Delaware corporation to limit or
eliminate the personal liability of directors to a corporation and its
stockholders for monetary damages for breach of fiduciary duty as a director
subject to certain limitations. The Culligan Certificate and the AMETEK
Certificate provide for the limitation of liability as permitted by Section
102(b)(7).
 
  While these provisions provide directors with protection from awards for
monetary damages for breaches of their duty of care, they do not eliminate
such duty. Accordingly, these provisions will have no effect on the
availability of equitable remedies such as an injunction or rescission based
on a director's breach of his or her duty of care. Also, these provisions do
not eliminate or limit the liability of a director for breach of the duty of
loyalty, acts or omissions not in good faith or involving intentional
misconduct or a knowing violation of law, unlawful dividends or stock
repurchases, or any transaction from which the director derived an improper
personal benefit. The provisions described above apply to an officer of a
corporation only if he or she is a director of such corporation and is acting
in his or her capacity as director, and do not apply to officers of the
corporation who are not directors.
 
INDEMNIFICATION OF OFFICERS AND DIRECTORS
 
  Section 145 of the DGCL provides that a Delaware corporation may indemnify
its officers and directors who are a party, or threatened to be made a party,
to any threatened, pending or completed action, suit or
 
                                      83
<PAGE>
 
proceeding by reason of the fact that he or she is or was a director, officer
or employee of the corporation by, among other things, a majority vote of
directors who were not parties to such action, suit or proceeding (whether or
not a quorum), provided that such officers and directors acted in good faith
and in a manner they reasonably believed to be in or not opposed to the best
interests of the corporation. The Culligan Certificate and Culligan By-laws
and AMETEK Certificate and AMETEK By-laws each provides for indemnification of
officers and directors as permitted by Section 145.
 
  Culligan has entered into indemnification agreements with each of Culligan's
directors and officers. The indemnification agreements require, among other
things, Culligan to indemnify the officers and directors to the fullest extent
permitted by law, and to advance such directors and officers all related
expenses, subject to reimbursement, if it is subsequently determined that
indemnification is not permitted. Culligan will also indemnify and advance all
expenses incurred by such directors and officers seeking to enforce their
rights under the indemnification agreements, and cover directors and officers
under Culligan directors' and officers' liability insurance. Although such
indemnification agreements offer substantially the same scope of coverage
afforded by the Culligan Certificate and Culligan By-Laws, they provide
greater assurance to directors and officers that indemnification will be
available because, as a contract, it cannot be modified unilaterally in the
future by the Culligan Board or by Culligan stockholders to eliminate the
rights provided therein.

                        ELECTION OF DIRECTORS OF AMETEK
 
           THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR ALL NOMINEES
   
  The entire AMETEK Board of eight directors is proposed to be elected at the
Special Meeting to hold office until the next annual meeting of stockholders
and until their respective successors have been duly elected and qualified.
These directors will resign as directors of AMETEK at the Effective Time but
will continue as the directors of New Ametek. See "MANAGEMENT" in the New
Ametek Information Statement which is included as Appendix E for additional
information concerning the New Ametek Board. All proxies received by the
AMETEK Board will be voted for the election, as directors, of the nominees
listed below if no direction to the contrary is given. Each nominee who
receives a plurality vote by ballot of the shares present in person or
represented by proxy and entitled to vote at the Special Meeting will be
elected as a director. In the event that any nominee is unable or declines to
serve, the proxy solicited herewith may be voted for the election of another
person in his or her stead. The AMETEK Board knows of no reason to anticipate
that this will occur.

                           COMPENSATION OF DIRECTORS
 
  The annual rate of compensation for services as a non-employee director of
AMETEK was revised effective January 1, 1996, to $35,000 per year plus $2,500
for each meeting attended. Mr. Blankley, the only employee director of AMETEK
in 1996, did not receive any compensation for his services as a director.
   
  Pursuant to a Retirement Plan for Directors (the "Directors Plan"), AMETEK
has agreed to provide retirement benefits and death benefits to those
directors who have not accrued benefits under the Employees' Retirement Plan
of AMETEK, Inc. and who have completed at least three years of service as a
director or officer of AMETEK. Effective January 1, 1997, the Directors Plan
was amended to limit participation to those Directors who became members of
the AMETEK Board prior to January 1, 1997. The retirement benefit payable
under the Directors Plan is an annual amount equal to 100% of the highest
annual rate of compensation for directors during the director's period of
service on the AMETEK Board; however, the benefit is reduced proportionately
if the participant has less than five years of service. AMETEK shall satisfy
its obligations arising under the Directors Plan exclusively from its general
assets. All of the current directors other than Mr. Blankley are participants
in the Directors Plan and each of these participants, other than Messrs.
Malone and Steinmann, has accrued an annual retirement benefit of $50,000. Mr.
Steinmann has accrued an annual retirement benefit of $40,000, and Mr. Malone
has accrued an annual retirement benefit of $30,000     
 
  Pursuant to a Death Benefit Program for Directors (the "Directors Program"),
AMETEK has entered into individual agreements with certain directors. The
agreements require AMETEK to pay death benefits to directors' designated
beneficiaries and to pay benefits to the directors under certain
circumstances. The Directors Program currently provides for a benefit, payable
for ten years, in an annual amount equal to 100% of the highest annual rate of
compensation during the director's period of service on the AMETEK Board,
commencing at death or the later of age 70 or retirement; however, with
respect to directors who became participants after January 1, 1989, the
directors must complete at least five years of service as a director before
they become eligible to receive a benefit upon the later of age 70 or
retirement. Active directors also have a group term life insurance benefit of
$50,000. To fund benefits under the Directors Program, AMETEK has purchased
individual life insurance policies on the lives of certain of the covered
directors. AMETEK retains the right to terminate any or all of the Directors
Program agreements under certain circumstances. All of the current directors
other than Mr. Blankley are participants in the Directors Program.

(1) The options granted in 1996 to Messrs. Blankley, Hermance, Marsinek,
    Molinelli, and Neupaver are exercisable after the first anniversary of the
    date of the grant (April 8, 1996) during each of the four succeeding
    twelve-month periods only to the extent of twenty-five percent of the
    total number of shares optioned. In all cases, optioned shares that may
    have been but were not purchased during any one twelve-month period may be
    purchased during any one or more succeeding twelve-month periods up to the
    expiration date of the option. Options generally become fully exercisable
    in the event of the holder's death, retirement or termination of
    employment in connection with a change in control.
(2) The amounts represent certain assumed rates of appreciation. Actual gains,
    if any, on stock option exercises are dependent on future performance of
    AMETEK's Common Stock. There can be no assurance that the rates of
    appreciation reflected in this table will be achieved.

(1) Benefit amounts assume a participant reaches age 65 in 1997; for younger
    participants, the benefit amounts are less than the amounts indicated
    above.
   
  At December 31, 1996, the executives named in the Summary Compensation Table
had the following years of credited service under the Retirement Plan: Mr.
Blankley-37; Mr. Hermance-6; Mr. Marsinek-32; Mr. Molinelli-28, and Mr.
Neupaver-20.     
 
  The annual compensation taken into account for any plan year is generally
equal to the participant's salary and any bonus accrued during the plan year
as reported in the Summary Compensation Table. Compensation in excess of
certain amounts prescribed by the Secretary of the Treasury ($160,000 for
1997) cannot be taken into account under the Retirement Plan. The individuals
named in the Summary Compensation Table are subject to
 
                                      93
<PAGE>
 
   
this limitation. However, in accordance with a nonqualified supplemental
pension arrangement that, as of the Spin-Off Date, New Ametek will assume,
AMETEK has agreed to provide to Mr. Blankley a benefit in an amount equal to
the excess of the annual pension benefit that would be payable to him under
the terms of the Retirement Plan in the absence of statutory restrictions over
the amount actually payable under the Retirement Plan. The benefit is limited
to the projected excess payable at age 65 determined as of May 21, 1991,
taking into account the statutory restrictions as of such date. Pursuant to an
agreement entered into with Mr. Blankley, a restricted stock award was granted
under the 1991 Stock Incentive Plan of AMETEK, Inc. for a number of shares of
AMETEK's Common Stock having a fair market value on the day of grant equal to
50% of the then present value of Mr. Blankley's projected benefit under the
supplemental pension arrangement. Effective with the Spin-Off and the Merger,
shares of New Ametek Common Stock and Culligan Common Stock will be
substituted for the AMETEK Common Stock in amounts consistent with the terms
of the Spin-Off and the Merger. The remaining portion of the benefit will be
payable in cash directly out of New Ametek's general assets. Under this
arrangement, Mr. Blankley does not receive an amount sufficient to provide him
with his full benefit under the Retirement Plan, since the amount of
compensation that can be taken into account under the statutory restrictions
in effect in 1991 has been subsequently reduced.     
   
  In addition, pursuant to the AMETEK, Inc. Supplemental Executive Retirement
Plan ("SERP") that, as of the Spin-Off Date, New Ametek will assume, AMETEK
has agreed, beginning in 1997, to credit to the account of certain executives,
including executives named in the Summary Compensation Table, an amount equal
to 13% of the executive's compensation in excess of the statutory restrictions
for each plan year, in order to compensate them for the loss of retirement
income under the Retirement Plan resulting from those restrictions. The
contribution for Mr. Blankley under the SERP will be limited to 13% of his
compensation that is not taken into account under the agreement described in
the preceding paragraph. The credited amounts shall be deemed to be invested
in AMETEK Common Stock and, upon retirement, shall be distributed in kind. In
addition, a one-time credit shall also be made to each such executive's
account equal to the value of the shares of common stock, if any, that would
have been credited to the executive's account had the SERP been in effect
since January 1, 1989. An executive's right to a benefit under the SERP will
become non-forfeitable at the same time as the executive's right to an accrued
benefit under the Retirement Plan (or the retirement feature of The AMETEK
Savings and Investment Plan) becomes non-forfeitable.     
 
  For retirements occurring in 1997, the maximum annual pension benefit
payable at normal retirement age is restricted, by law, to the greater of
$125,000 or the amount of such benefit determined under the Retirement Plan
and prior existing law as of December 31, 1982. The $125,000 limit is adjusted
annually by the Secretary of the Treasury to reflect increases in the cost of
living.
 
  Persons joining AMETEK after January 1, 1997 are not eligible to participate
in the Retirement Plan, but instead are eligible to participate in a new
defined contribution feature of AMETEK's 401(k) Plan.

            COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION
   
  The following report, submitted by the Compensation Committee of the AMETEK
Board of Directors (the "Compensation Committee"), provides information
regarding policies and practices concerning compensation of the Chairman of the
Board and Chief Executive Officer and the other executive officers of AMETEK.
    
COMPENSATION OVERVIEW
 
  The functions performed by the Compensation Committee include recommending to
the Board of Directors (a) remuneration arrangements for senior management and
directors and (b) compensation plans in which officers and employees are
eligible to participate. Members of the Compensation Committee are directors
who are not employees of AMETEK. The current members of the Compensation
Committee are Messrs. Gordon, Klein and Malone and Ms. Varet.
 
  Executive compensation consists of three principal elements: (a) salary; (b)
annual bonus and (c) grants of stock options and stock appreciation rights and
restricted stock awards under AMETEK plans. Additional retirement and other
benefits are provided for AMETEK's executives similar to those typically
provided by other major corporations.
 
  Decisions about executive officers' salary and bonus are made under the
supervision of the Compensation Committee, while decisions concerning
compensation in the form of stock options, SARs and restricted stock awards are
made under the supervision of the committee of the Board of Directors
designated for the appropriate plan. The members of each of these plan
committees currently are the same as the members of the Compensation Committee;
thus, references in this report to the "Compensation Committee" should be read
where appropriate, as references to the various plan committees.
 
  Underlying the Compensation Committee's decisions with respect to executive
officers' compensation is the belief that it is fundamentally important that
AMETEK attract, retain, motivate and benefit from the guidance and experience
of talented and qualified individuals so that AMETEK's short-term and long-term
success will continue and its profitability and worldwide reputation for
quality, and thus stockholder value, will grow. AMETEK also believes that its
officers and executives have been encouraged to acquire a larger equity
interest in AMETEK, thereby having additional incentives, corresponding to the
interests of stockholders, to put forth their maximum efforts for the success
and profitability of AMETEK's businesses and the achievement of increased
stockholder value. Information regarding similarly situated executive officers
at comparable companies was drawn from publicly available information for
certain of the companies included in the index of companies used in the
Performance Graphs set forth on page 94 and for certain other companies
identified by an independent employee benefits consulting firm retained by
AMETEK. It is the current intention of the AMETEK Board and the Compensation
Committee to continue the above practices.
 
SALARY
 
  Salary levels for AMETEK's executive officers are established principally on
the basis of the executive's responsibilities. In each case, consideration is
given both to personal factors such as the individual's experience and record
and the responsibility associated with his or her position and to external
factors such as salaries paid to similarly situated executive officers by
comparable companies and prevailing conditions in the geographic area where the
executives' principal services will be performed. Comparable companies were
identified as described above. Annual adjustments to each executive officer's
salary are determined based on the foregoing factors but with due consideration
also being given to prevailing economic conditions, to the relationship of such
adjustments to those being given to other employees within AMETEK, to the
performance of the executive's duties and responsibilities and to other
individual performance-related criteria that may be relevant with respect to
such executive officer at the time. In evaluating the salaries paid to
similarly situated executive officers, consideration is given to the full range
of such salaries and to the experience and records of those executives who
received salaries at the high, medium and low points of such range. In
determining executive salaries, the Compensation Committee has generally
targeted the median level of the compensation range for comparable companies.
In addition, in establishing salary levels, consideration is given to the
competitiveness of the total annual compensation received by AMETEK's executive
officers as compared to the total compensation received by other similarly
situated executive officers.
 
                                       95

ANNUAL BONUS
 
  Bonuses are viewed as a reward for individual contributions to AMETEK's
performance, based not only on AMETEK's short-term results but also on the
investments made by AMETEK for the future growth of AMETEK's profits. In
addition, consideration is given to the achievement of selected financial
goals (i.e., operating performance, asset management and business growth
development) and progress in meeting other long-term objectives, as well as
the executive officers' leadership role in these activities. Bonus decisions
generally are made toward the end of each year. Pursuant to AMETEK's
Additional Compensation Plan, each year an aggregate amount, generally equal
to five percent of income before federal income taxes exclusive of capital
gains and certain non-recurring charges, is accrued for the purposes of paying
bonuses to executive officers and certain other employees. As a result of
overall performance in 1996, which met or exceeded the targeted financial
goals referred to above, the bonus pool for 1996 increased compared to 1995.
The Chairman of the Board and Chief Executive Officer reviews performance by
AMETEK and the individual contributions of each executive officer to AMETEK's
performance and makes recommendations to the Compensation Committee with
respect to the suitable bonus amount to be awarded to such individual for that
year based on such review. The Compensation Committee then meets with the
Chairman of the Board and Chief Executive Officer to consider such
recommendations, makes any changes that may be deemed appropriate, and
presents its recommendations to the Board of Directors which then discusses
and votes upon the bonuses. The principal financial performance measures
considered by the Compensation Committee are earnings, return on assets and
cash flow, with the relative weight of each of these factors being roughly
equal. However, the significance of any one of these factors may vary from one
executive officer to another depending upon whether that officer has been
assigned other long-term goals, such as reorganizing a business line,
developing new products or increasing market penetration for current products.
 
                STOCK OPTIONS, SARS AND RESTRICTED STOCK AWARDS
 
  Awards of stock options, SARs and shares of restricted stock are considered
an important complement to the cash elements of AMETEK's executive officers'
compensation described above and have the purpose of aligning the executives'
interests with the stockholders' interests. The plans under which such awards
are made have been approved by AMETEK's stockholders. AMETEK stock options and
SARs generally require the executive to be employed by AMETEK on the exercise
date and become exercisable in stages over a period of years following the
date of grant. The exercise price of options generally equals the mean market
price of AMETEK's stock on the grant date; accordingly, such options will only
yield income to the executive if the market price of AMETEK's stock is
greater, at the time of exercise, than it was when the option was granted.
Although AMETEK has not yet done so, it could grant options with average
prices greater than the market price of AMETEK's stock on the grant date in
order to vary the long-term incentive being created for the option recipient.
It is believed that a principal factor influencing the market price of
AMETEK's stock is AMETEK's performance as reflected in its sales, earnings,
cash flow and other results; thus, by granting stock options and SARs to
AMETEK's executive officers, such individuals are encouraged to achieve
consistent improvements in AMETEK's performance. Awards of shares of
restricted stock are subject to forfeiture restrictions which prohibit the
recipient from selling such shares until the specified period of restriction
following the date the award lapses. Such awards provide inducements to the
executive officers to remain with AMETEK over the long term and to work to
enhance corporate performance and, correspondingly, stockholder value. When
considering whether to make grants of stock options and SARs or awards of
restricted stock, the Compensation Committee reviews practices of other
comparable companies (which are identified as described above) as well as
individual performance-related criteria such as those already described, and
takes into consideration the effect such awards might have on AMETEK's
performance and stockholder value. The measures of AMETEK's performance that
are considered in making such awards, and the relative weight of each of these
factors, are the same as those used in determining bonus levels, which are
described above. The long-term objectives that an officer has been assigned
are also considered. However, in determining to grant options or SARs or award
restricted stock, the Compensation Committee has generally placed greater
emphasis on long-term objectives than it has in its determination of bonus
awards.
 
 
                                      96
<PAGE>
 
   
  The Compensation Committee believes that stock ownership by executive
officers can help strengthen the alignment of interests between AMETEK's
management and shareholders. Upon the suggestion of and in consultation with
AMETEK's Chief Executive Officer, the Compensation Committee has established
guidelines for stock ownership by its executive management. Although these
guidelines are non-binding, it is expected that each executive officer of
AMETEK will work toward achieving the target levels. It is assumed that such
levels can be reached by an executive officer within a 5 year period. To reach
his or her target level, an executive officer must own AMETEK shares having a
market value at least equal to a specified multiple of such executive
officer's base salary. The multiples established by the Compensation Committee
are 5 in the case of the Chief Executive Officer, 4 in the case of the Chief
Operating Officer, 3 in the case of a Senior Vice President and 2 in the case
of any other executive officer. In its awarding of future option grants, the
Compensation Committee intends to take account of the progress made by an
executive officer in reaching the target ownership level.     
 
                       MR. BLANKLEY'S 1996 COMPENSATION
 
  In determining the appropriate levels for Mr. Blankley's 1996 base salary,
bonus and stock option grant, the Compensation Committee considered the same
factors that it considered when fixing compensation levels for AMETEK's other
executive officers and sought to achieve the same corporate goals. The
Compensation Committee also considered the major initiatives and programs
which, in 1996, were commenced or furthered under Mr. Blankley's leadership,
such as: (a) recognition of additional cost benefits resulting from AMETEK's
plan to enhance stockholder value adopted in November 1993, together with
substantial progress in implementing the operating strategies called for by
such plan; (b) continued development of a deeper and more experienced senior
management team; (c) continued improvements in asset management throughout
AMETEK, including the reduction of inventory levels and cycle time resulting
from the introduction of flow management as part of AMETEK's TQM effort; (d)
establishment of a majority owned joint venture operation in Shanghai, PRC for
the production of electric motors; (e) substantial progress in establishing
operations and pursuing other opportunities in various Eastern European and
other emerging market locations, including the opening of production
facilities for electric motors in the Czech Republic and Mexico and (f)
continued progress in expanding its international sales activities. Certain
personal criteria also were reviewed, such as the fact that 1996 was the
fourth year of Mr. Blankley's service as Chairman of the Board and Chief
Executive Officer after more than 35 years of service with AMETEK in many
positions including the position of President. The Compensation Committee also
evaluated data regarding CEO compensation practices of other comparable
companies (which were identified previously) so that Mr. Blankley's total
compensation package would be in line with that of CEOs in such other
companies. A major factor in fixing Mr. Blankley's bonus was the fact that
AMETEK achieved essentially all of its financial goals established for 1996,
including earnings per share, return on assets and cash flow.
 
                                SECTION 162(M)
 
  Section 162(m) of the Code generally limits the deductibility by a publicly-
held corporation of compensation paid in a taxable year to the Chief Executive
Officer and any other executive officer whose compensation is required to be
reported in the Summary Compensation Table to $1,000,000. For the 1996 taxable
year, AMETEK did not exceed, and therefore was not affected by, this
limitation.

                           STOCK PERFORMANCE GRAPHS
 
  AMETEK re-evaluated the composition of its Industry Performance Peer Group
as of December 31, 1996, and determined that a change was appropriate. The new
Industry Performance Peer Group is the Dow Jones Electrical Components and
Equipment Industry Group ("DJEE"). The former Industry Performance Peer Group
consisted of two separate industry groups published by Business Week as the
"Electrical Products" and "Instrument" groups. Through investor
communications, AMETEK has learned that the investing public cannot easily
access the cumulative total return performance of AMETEK's former Performance
Peer Group. For these reasons, AMETEK believes the change is appropriate.
AMETEK believes its new Industry Performance Peer Group will provide current
and potential investors with information that is more readily available and
with an industry group that is a more relevant comparison for purposes of
evaluating stock performance and AMETEK's executive compensation.
 
  Assuming an initial investment of $100 invested on December 31, 1991, and
the reinvestment of all dividends, the following graphs compare AMETEK's
cumulative total return plotted on an annual basis, with the S&P 500 Index and
the new and former Performance Peer Groups. The first graph compares AMETEK's
cumulative total return for the previous five years to the new Performance
Peer Group (DJEE). As required by the Securities and Exchange Commission, a
second graph has also been provided which compares AMETEK's cumulative total
return for the same five-year period to the former Performance Peer Group.

          COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
  Sheldon S. Gordon, Charles D. Klein, James R. Malone and Elizabeth R. Varet
have comprised the Compensation Committee. Mr. Klein and Ms. Varet are
managing directors of American Securities, L.P., an investment banking firm.
   
  The law firm of Stroock & Stroock & Lavan LLP, of which Mr. Cole is a
member, rendered during 1996 and continues to render services as General
Counsel for AMETEK and its subsidiaries. The investment banking firm of
American Securities, L.P., and affiliates of American Securities, L.P.,
including Oak Hall Capital Advisors, L.P., rendered during 1996 and continues
to render financial advisory, investment management and other services to
AMETEK. American Securities, L.P. is controlled, indirectly, through family
trusts of which Ms. Varet and Mr. Cole are co-trustees, by Ms. Varet and
members of her family and by Messrs. Steinmann and Klein.     
 
                       COMPLIANCE WITH SECTION 16(A) OF
                      THE SECURITIES EXCHANGE ACT OF 1934
 
  Section 16(a) of the Exchange Act requires AMETEK's directors and officers
to file with the Commission and the New York Stock Exchange initial reports of
ownership and reports of changes in ownership of AMETEK's Common Stock. Copies
of all such Section 16(a) reports are required to be furnished to AMETEK.
 
                                      99
<PAGE>
 
These filing requirements also apply to holders of more than ten percent of
AMETEK's Common Stock; to AMETEK's knowledge, such holders are those listed in
the table in "--Stock Ownership." To AMETEK's knowledge, based solely on a
review of the copies of Section 16(a) reports furnished to AMETEK and written
representations that no other reports were required, during the fiscal year
ended December 31, 1996, AMETEK's officers and directors were in compliance
with all Section 16(a) filing requirements.
 
              EMPLOYMENT CONTRACTS AND TERMINATION, SEVERANCE AND
                        CHANGE-IN-CONTROL ARRANGEMENTS
          
  AMETEK has entered into change of control agreements with most of its
executive officers, including the executives listed in the Summary
Compensation Table, which agreements New Ametek will assume effective as of
the Spin-Off Date. The purpose of the agreements is to assure the continued
attention and dedication of key executives when AMETEK is faced with a
potential change of control by providing for some continuation of the
executive's compensation and benefits. Under the agreements, the sum of the
executive's prior year's salary, plus the greater of (a) the current year's
bonus, or (b) the average of the two prior years' bonuses (as limited under
Section 280G of the Code) will be continued for a period of one, two or three
years (as defined in each executive's agreement), and health benefits will be
continued until Medicare eligibility, coverage under another group health
plan, or ten years or the executive's death, whichever is earlier, in the
event that the executive's employment is terminated by AMETEK without cause or
by the executive for good reason within two years after a Change of Control.
For purposes of the agreements, a "Change of Control" means that the
acquisition of 20% or more of the voting stock of New Ametek by a party other
than AMETEK (or its affiliates), or a merger or consolidation after which the
stockholders of AMETEK do not own or control at least 50% or more of the
voting stock of AMETEK, or any sales or other disposition of all or
substantially all of AMETEK's assets, or a plan of liquidation is approved.
None of the events related to the Spin-Off or the Merger will be deemed to
constitute a Change of Control.     
 
  Pursuant to a Supplemental Senior Executive Death Benefit Program (the
"Program"), AMETEK has entered into individual agreements with certain
executives. The agreements require AMETEK to pay death benefits to their
designated beneficiaries and to pay benefits to the executives under certain
circumstances. If a covered executive dies before retirement or before age 65
while on disability retirement, the executive's beneficiary will receive
monthly payments from the date of the executive's death until the date he or
she would have attained age 80, but not less than for 15 years (the 15-year
minimum guarantee does not apply to executives whose inclusion in the Program
is approved after December 31, 1986). The specified dollar amount of the
payments is determined on the basis of the executive's salary and age. In
addition, the standard death benefit payable for participants in the Program
from AMETEK's group term life insurance policy was revised effective January
1, 1996, to two times the executive's annual salary, limited to $200,000. If a
covered executive retires, or reaches age 65 while on disability retirement,
the Program provides for an annual benefit of one-tenth of an amount equal to
the lesser of (a) twice the executive's average annual base salary for the
last five full years of service, rounded off to the next highest multiple of
$50,000 or (b) a maximum amount specified in the agreement. The highest
maximum amount specified in the existing agreements is $1,000,000. The benefit
is payable monthly over a period of 10 years to the executive or the
executive's beneficiary. The payments will commence for retirees at age 70 or
death, whichever is earlier. However, if the executive retires after age 70,
the payments commence on retirement.
 
  To fund benefits under the Program, AMETEK has purchased individual life
insurance policies on the lives of certain of the covered executives. AMETEK
retains the right to terminate all of the Program agreements under certain
circumstances. Messrs. Blankley, Hermance, Marsinek, Molinelli and Neupaver
are participants in the Program.

                        REPORT OF INDEPENDENT AUDITORS
 
The Board of Directors and Stockholders of AMETEK, Inc.
 
  We have audited the accompanying combined balance sheets of The Water
Filtration Business (a wholly owned business of AMETEK, Inc.) as of December
31, 1996 and 1995, and the related combined statements of income and cash
flows for each of the three years in the period ended December 31, 1996. These
financial statements are the responsibility of AMETEK's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the combined financial position of The Water
Filtration Business (a wholly owned business of AMETEK, Inc.) at December 31,
1996 and 1995, and the combined results of its operations and its cash flows
for each of the three years in the period ended December 31, 1996, in
conformity with generally accepted accounting principles.

                    NOTES TO COMBINED FINANCIAL STATEMENTS
 
1. BASIS OF PRESENTATION AND DESCRIPTION OF BUSINESS
 
 Basis of Presentation
 
  The accompanying combined financial statements present the financial
position, results of operations and cash flows of the Water Filtration
Business (the "Water Filtration Business") owned directly or indirectly by
AMETEK, Inc. ("AMETEK") and its subsidiaries. The accompanying combined
financial statements have been prepared on a historical cost basis and present
financial information for the Water Filtration Business as derived from
AMETEK's historical cost financial accounts. All significant intercompany
accounts and transactions of the Water Filtration Business have been
eliminated.
 
 Description of Business
 
  The Water Filtration Business is primarily in the business of manufacturing
water filtration products for retail, residential, commercial and industrial
customers in the United States and many foreign countries worldwide. The Water
Filtration Business sells its products through both retail and wholesale
distribution channels. It has a broad line of cartridge filtration products,
offering whole-house, countertop and other complete water filtration systems.
The Water Filtration Business's point-of-use drinking water filters and
cartridges are designed for the removal of objectionable taste, odor,
hazardous chemicals and bacteria. In addition, the Water Filtration Business
produces filters, housings and cartridges for use in food and beverage
dispensing, cosmetics and chemical production applications; as well as for use
by plumbing professionals to serve their residential and commercial customers.
 
  The Water Filtration Business's operations consist of Plymouth Products, a
United States division of AMETEK, and three wholly owned foreign subsidiaries:
AMETEK Filters, Limited; APIC International S.A.("APIC"); and AFIMO S.A.M.
("AFIMO").
 
2. THE WATER FILTRATION BUSINESS MERGER
 
  On February 5, 1997, AMETEK announced that it will separate all of its other
businesses from the Water Filtration Business and a wholly owned subsidiary of
Culligan Water Technologies, Inc. ("Culligan") will be merged with and into
the Water Filtration Business for a total purchase price to Culligan of
approximately $155 million. The purchase price, less assumed debt, is payable
to AMETEK's stockholders in Culligan common stock valued at $37.50 per share.
Following the merger, Culligan will assume $25 million of AMETEK's debt. Based
on the assumption of $25 million of AMETEK's debt, Culligan will distribute
3,466,667 shares of its common stock to AMETEK's stockholders, or 0.11 shares
of Culligan common stock for each outstanding share of AMETEK common stock
(based on shares outstanding at December 31, 1996).
 
  The transaction is subject to certain conditions, including receipt of a
favorable ruling from the Internal Revenue Service to the effect that the
merger and distribution will be tax-free for federal income tax purposes, and
approval by AMETEK's stockholders.
 
  In connection with the merger of the Water Filtration Business into
Culligan, AMETEK will enter into certain contractual agreements with Culligan.
Such agreements include an Indemnification Agreement, a Tax Allocation
Agreement, a Trademark Agreement and a Transition Services Agreement. The
agreements will provide, among other things, each party's rights and
obligations with respect to tax matters, use of trade names, certain
indemnification matters, and support services to facilitate an orderly
transition as they relate to the Water Filtration Business.

              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
 
 
3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
 Revenue Recognition
 
  The Water Filtration Business's revenues are recorded when products are
shipped and services are rendered. The policy with respect to sales returns
and allowances generally provides that the customer may not return the
products, or be given allowances, except at the Water Filtration Business's
option. The provision for estimated warranty costs (not material in amount) is
recorded at the time of sale and periodically adjusted to reflect actual
experience.
 
 Cash Management
 
  AMETEK uses a centralized cash management system for all of its domestic
operations, including that of the Water Filtration Business. Cash and cash
equivalents, consisting of highly liquid investments with maturities of three
months or less when purchased, reflected in the combined balance sheet,
represents balances maintained by the Water Filtration Business's foreign
operations.
 
 Inventories
 
  Inventories are stated at lower of cost or market, cost being determined on
a first-in, first-out (FIFO) basis. Reserves are provided for obsolete
inventory and for slow moving inventory based on historical and projected
usage.
 
 Property, Plant and Equipment
 
  Property, plant and equipment are stated at cost. Depreciation of property,
plant and equipment is calculated principally on the straight-line method
(accelerated methods for tax purposes) over the useful lives of the assets.
Expenditures for maintenance and repairs, which do not materially extend the
lives of the assets, as well as expenditures for tools and dies, are included
in operations as incurred.
 
  Financial Accounting Standards Board Statement No. 121, Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of,
which established new accounting standards for measuring the impairment of
long-lived assets, was adopted by the Water Filtration Business in the first
quarter of 1996. The adoption of this new Statement did not have any impact on
the Water Filtration Business's combined financial position or results of
operations.
 
 Advertising Costs
 
  Costs incurred for producing and communicating advertising are expensed when
incurred, including costs incurred under the Water Filtration Business's
cooperative advertising programs with its dealers and mass merchandisers.

                   (A WHOLLY OWNED BUSINESS OF AMETEK, INC.)
 
              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
 
 Intangible Assets
 
  Intangible assets consists of goodwill, and other acquired intangibles. For
financial reporting purposes, goodwill is being amortized on a straight-line
basis over 20 to 30 years. The other acquired intangibles are being amortized
over their estimated useful lives of five to seven years. The Water Filtration
Business reviews the carrying value of intangibles for impairment whenever
events or changes in circumstances indicate that the carrying amount may not
be recoverable.
 
 Foreign Currency Translation
 
  Results of operations of foreign subsidiaries are translated to U.S. dollars
by using the average exchange rates during the year. The assets and
liabilities of those subsidiaries are translated into U.S. dollars using the
exchange rates in effect at the balance sheet date. The related foreign
currency translation adjustments are recorded in a separate component of net
worth.
 
 Income Taxes
 
  The results of the Water Filtration Business's U.S. operations are included
in AMETEK's consolidated United States federal and state income tax returns.
The provision for income taxes included in these combined financial statements
represents the Water Filtration Business's allocated share of AMETEK's
domestic income tax expense (including a credit attributable to U.S. export
sales), which approximates the net expense that the Water Filtration Business
would have incurred on a separate tax return basis, along with the actual
income tax provisions of its foreign subsidiaries.
 
  As part of the plan of the merger, AMETEK and Culligan have entered into a
Tax Matters Agreement. This agreement generally provides that for periods
prior to the merger the two companies will retain the liability for any unpaid
taxes attributable to their respective operations.
 
 Research and Development
 
  Water Filtration Business-funded research and development costs are charged
to operations as incurred. The amounts charged to operations during the years
ended December 31, 1996, 1995 and 1994 were $600,000, $500,000 and $300,000,
respectively.
 
4. ACQUISITION
 
  On November 1, 1995, the Water Filtration Business purchased APIC and AFIMO,
a French- and Monaco-based manufacturer of water filtration products, for $5.7
million cash. Accounting for this acquisition was completed in early 1996 upon
the determination of fair values of the assets acquired and the liabilities
assumed. The acquisition was accounted for by the purchase method and the
results of APIC's and AFIMO's operations are included in the Water Filtration
Business's combined results from the date of acquisition.
 
  Assuming that the acquisition was made as of January 1, 1994, pro forma
unaudited net sales would have been $63.0 million for 1995 and $60.6 million
for 1994. Pro forma operating income and net income for 1995 and 1994 would
not have been materially different from the amounts reported.
 
5. TRANSACTIONS WITH AMETEK
 
  Net worth as shown in the combined balance sheet primarily represents
AMETEK's cumulative net investment in the combined business of the Water
Filtration Business. AMETEK's practice is to incur indebtedness for its
domestic operations at the parent company level, or at a limited number of
foreign

subsidiaries, and to centrally manage various cash functions for its domestic
operations. The Water Filtration Business's financing requirements have,
therefore, been substantially satisfied by transactions with AMETEK. There are
no material intercompany purchase or sale transactions between AMETEK and the
Water Filtration Business. Advances from AMETEK and excess cash sent to AMETEK
are reflected as net transactions with AMETEK and are included in net worth.
No interest is charged, or has been otherwise allocated to the Water
Filtration Business on outstanding balances due AMETEK.
 
  The following table sets forth the changes in net worth.

  Cumulative losses from foreign currency translation adjustment included in
the net worth shown above at December 31 are as follows: 1996--$647,000;
1995--$533,000; 1994--$519,000.
 
  At December 31, 1996, the Water Filtration Business's U.K. subsidiary,
Ametek Filters, Limited, had non-interest bearing notes payable to a
subsidiary of AMETEK totaling $343,000. The notes are payable in 2002, but are
being accelerated for payment in 1997, prior to the merger. The amount due is
shown as notes payable in the accompanying combined balance sheet.
 
  The Plymouth Products Division participates with other AMETEK Divisions in a
number of risk management, insurance and employee benefit programs, some of
which are self insured directly by AMETEK, or insured through its captive
insurance subsidiary. An estimate of the expense attributable to the Plymouth
Products Division for such programs is reflected in the combined statement of
income. The combined balance sheet includes accruals for specific workers'
compensation and product liability claims of the Plymouth Products Division
which were transferred through the intercompany account with AMETEK (see note
6).
 
  Certain operating expenses, capital expenditures, general corporate
expenses, and other cash requirements of the Water Filtration Business were
paid or accrued by AMETEK and charged directly or allocated to the Water
Filtration Business. Amounts included in the combined statement of income
related to the services provided to the Water Filtration Business by AMETEK
amounted to approximately $1.7 million in 1996, $1.4 million in 1995, and $1.3
million in 1994.
 
  These charges and allocations include amounts for consulting, legal and
other support services and were based on direct charges and an estimate of the
proportion of such corporate expenses related to the Water Filtration Business
for the periods presented and, in the opinion of management, have been made on
a reasonable basis.

8. PENSION PLANS
   
  The Water Filtration Business maintains a noncontributory defined benefit
pension plan for eligible U.S. hourly employees. Additionally, eligible U.S.
salaried employees participate in AMETEK's salaried pension plan. Benefits are
generally based on years of service and average compensation. Pension costs
under these plans are funded through a trust established in connection with
the plans, which is maintained by AMETEK. Assets of the trust are principally
invested in a variety of equity and debt instruments. Pension expenses
(excluding administrative expenses) associated with these plans are charged
directly to the Water Filtration Business and are shown in the table below.
AMETEK's funding policy with respect to these plans is to contribute amounts
determined annually on an actuarial basis that provide for current and future
benefits in accordance with funding requirements of federal law and
regulation. In connection with the Merger, AMETEK will transfer to New Ametek
all liabilities with respect to pension benefits of the Water Filtration
Business's U.S. salaried employees. Accordingly, no pension-related assets or
liabilities associated with the salaried U.S. employees are included in the
accompanying combined balance sheet. Employees of the foreign operations are
covered by pension arrangements in their individual country of operation and
no liabilities associated with these arrangements are included in the balance
sheets.     
 
  Net pension expense consists of the following components:

  Net pension expense reflects an expected long-term rate of return on plan
assets of 9 1/4% for 1996, 1995 and 1994. The actual return has been adjusted
to defer gains and losses that differ from the expected return. The present
value of the projected benefit obligation was determined by using an assumed
discount rate of 7 3/4% in 1996, 7 1/2% in 1995 and 7 3/4% in 1994. The
balance sheet reflects an additional long-term pension liability of $400,000
($462,000 in 1995), a long-term intangible asset of $221,000 ($235,000 in
1995), and a change in net worth (net of deferred taxes) of $116,000 in 1996
($148,000 in 1995).

              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
   
  The Water Filtration Business provides benefits to eligible U.S. employees
through participation in the AMETEK Saving and Investment Plan, a defined
contribution plan. Expenses relating to this plan in 1996, 1995, and 1994 were
not material.     
 
  The Water Filtration Business does not provide significant postretirement or
postemployment benefits other than pensions.
 
9. LEASES
 
  Future minimum lease payments under non-cancelable leases with remaining
terms of more than one year amounted to $1,637,000, consisting of annual
payments of $442,000 in 1997, and decreasing amounts thereafter.
 
  Rent expense under operating leases of $761,000 was charged to income in
1996, $244,000 in 1995, and $202,000 in 1994.
 
10. STOCK OPTIONS
 
  AMETEK has certain Stock Option Plans under which incentive stock options,
stock appreciation rights, restricted stock awards and phantom stock awards
may be granted to officers and key employees. In connection with the
separation of the water filtration business, employees of the Water Filtration
Business with options in the Plans that are not exercised prior to the
effective date, will either be converted into their cash value or Culligan
options, at the election of the employee, based on a formula that preserves
the inherent economic value and vesting terms and provisions of such AMETEK
options. Stock options for 113,140 shares of AMETEK common stock at prices
ranging from $11.69 to $19.19 were outstanding at December 31, 1996. Stock
options for 50,590 shares were exercisable at December 31, 1996.

(a)  Fourth quarter 1996 reflects the short-term impacts of a soft economy in
     Europe, the impact of changes in foreign currency exchange rates, and the
     residual effects of a two week truckers' strike in France. The fourth
     quarter of 1996 also reflects the recognition of higher than normal
     charges related to advertising and sales promotion programs in the Water
     Filtration Business's retail water filtration market.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
          AND RESULTS OF OPERATIONS OF THE WATER FILTRATION BUSINESS
 
  Management's discussion and analysis of the Water Filtration Business's
financial condition and results of operations set forth below should be read
in conjunction with the Selected Combined Historical Financial Data of the
Water Filtration Business and the Combined Financial Statements of the Water
Filtration Business and the notes thereto.
 
BUSINESS OVERVIEW
   
  The Water Filtration Business of AMETEK consists of a United States
division, the Plymouth Products Division, and three foreign subsidiaries,
Ametek Filters, Limited, APIC International S.A. ("APIC") and AFIMO S.A.M.
("AFIMO"). All of AMETEK's businesses other than the Water Filtration Business
are to be separated from AMETEK, and Culligan Merger Sub is to be merged with
and into AMETEK. See "The Water Filtration Business Merger" in Note 2 to the
audited Combined Water Filtration Business Financial Statements.     
   
  The Water Filtration Business's primary business is the manufacturing of
water filtration cartridge products for retail, residential, commercial, and
industrial markets in the United States and many countries worldwide. The
Water Filtration Business sells its products to both the retail and wholesale
distribution channels, including direct sales to the plumbing industry to
serve their residential and commercial customers. It is a leader in point-of-
use drinking water filters and cartridges designed for the removal of
objectionable taste, odor, hazardous chemicals and bacteria from water. Its
products also include filter cartridges and housings which are used in diverse
applications such as food and beverage dispensing, cosmetics, and chemical
production applications. For the three months ended March 31, 1997 and for
years 1996 and 1995, sales to commercial and industrial markets accounted for
approximately 50% of the Water Filtration Business's net sales. In all
periods, sales to retail and residential markets were about 40% of the Water
Filtration Business's net sales and utility and turf irrigation products
accounted for the remainder of the sales.     
   
THREE MONTHS ENDED MARCH 31, 1997 COMPARED TO THREE MONTHS ENDED MARCH 31,
1996     
   
 Results of Operations     
   
  Sales for the first quarter of 1997 were $18.7 million, relatively unchanged
from $18.5 million of sales recorded for the same quarter of 1996. Higher
exports by the Water Filtration Business's U.S. operation were largely offset
due to lower sales by the European operations. Sales performance also varied
by market segment, with higher sales in the waste treatment, industrial and
utility/turf irrigation markets and by lower sales to the retail and
commercial markets.     
   
  Selling, general and administrative expenses were $2.9 million in the first
quarter of 1997, compared with $2.4 million in the first quarter of 1996, an
increase of 18.1%. Selling expenses as a percentage of sales increased to
15.4% of sales in the 1997 first quarter, compared with 12.8% of sales in the
same quarter of 1996. The increased proportion of selling expenses was due
partially to higher advertising and sales commission expenses in the retail
business of the U.S. operation, and from a relatively higher proportion of
selling expenses from the APIC and AFIMO French and Monaco operations.     
   
  Operating income for the first quarter of 1997 was $3.3 million, compared
with $3.6 million in the 1996 first quarter, a decrease of 10.3%. Operating
income as a percentage of sales was 17.5% in the 1997 first quarter, compared
with 19.7% in the first quarter of 1996. The lower operating margin was due to
the higher proportion of selling expenses mentioned above.     
   
  The effective tax rate for the first quarter of 1997 was 32.1%, compared
with 35.7% for the same quarter of 1996. The lower 1997 rate was due partly to
a lower state tax provision for the U.S. operation, and to lower taxes on
foreign earnings.

  The effects of the above items resulted in net income for the first quarter
of 1997 of $2.2 million, compared with $2.3 million in the same quarter of
1996, a decrease of $.1 million or 5.5%.     
       
YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995
 
 Results of Operations
 
  For 1996, sales were $68.6 million, compared to $55.6 million in 1995, an
increase of $13.0 million or 23.4%. Increased market penetration into the
worldwide water treatment and retail markets, and the introduction of new
products into the industrial filtration markets by the Water Filtration
Business's United States operations, plus the full year's sales contribution
from the November 1995 acquisition of APIC and AFIMO, contributed almost
equally to the sales increase. Export shipments from the U.S. continued an
increasing trend, growing $1.6 million or 20.7% to $9.6 million in 1996.
 
  Selling, general and administrative expenses were $10.3 million in 1996,
compared to $7.5 million in 1995, an increase of $2.9 million or 38.2%.
Selling expenses as a percentage of sales increased to 14.7% of sales in 1996
compared to 13.0% of sales in 1995. The increased proportion of selling
expenses was due partially to higher advertising and sales commission expenses
related to penetration of highly competitive U.S. channels, including mass
merchandisers and national home center chains, and from a relatively higher
proportion of selling expenses from the APIC and AFIMO acquisition.
 
  Operating income for 1996 was $12.4 million, compared to $10.8 million in
1995, an increase of $1.5 million or 14.2%. The profit increase reflected the
higher sales volume, including the full year profit contribution of the APIC
and AFIMO acquisition. Operating income as a percentage of sales was 18.0% in
1996, compared with 19.5% in 1995. The lower operating margin was due to the
higher proportion of selling expenses in 1996, and a lower proportion of
earnings from the APIC and AFIMO acquisition.
 
  The effective tax rate for 1996 was 33.9%, compared to 35.5% for 1995. The
lower 1996 rate was due primarily to lower foreign taxes, mostly from the
Water Filtration Business's United Kingdom ("U.K.") operation, which benefited
from net operating loss carryforwards.
 
  The effects of the above items resulted in net income for 1996 of $8.2
million, compared to $7.0 million in 1995, an increase of $1.2 million or
16.6%.
 
YEAR ENDED DECEMBER 31, 1995 COMPARED TO YEAR ENDED DECEMBER 31, 1994
 
Results of Operations
 
  For 1995, sales were $55.6 million, an increase of $1.6 million or 2.9%
compared to 1994 totals. The sales increase came primarily from the Water
Filtration Business's United States operation, resulting from expansion into
worldwide industrial and water treatment filtration markets, and to higher
sales of new industrial filtration products by the Water Filtration Business's
U.K. operation. Export sales from the Water Filtration Business's United
States operation increased $1.1 million to $8.0 million in 1995, an increase
of 16.5%. The overall sales increase however, was largely offset by lower
domestic sales in the retail and commercial markets. Sales to the Walter
Filtration Business's retail markets declined in 1995 from 1994 levels,
primarily due to adverse winter weather conditions, which had a diminishing
effect on consumer buying in early 1995.
 
  Operating profit margins decreased to 19.5% in 1995 from 22.0% in 1994, due
to reduced operating efficiencies, primarily from the United States operation.
Higher engineering, product development and new product introduction costs
were absorbed in 1995 in preparation for sales growth in 1996. The effects of
the above items more than offset the profit contribution from the sales
increase, resulting in operating income for 1995 of $10.8 million, a decrease
of $1.1 million or 9.2% from 1994.
 
  Net income for 1995 was $7.0 million, compared to $7.7 million in 1994, a
decrease of $.7 million or 9.5%, reflecting the lower operating margins
discussed above.

LIQUIDITY AND CAPITAL RESOURCES
   
 March 31, 1997 Compared to December 31, 1996     
   
  Working capital at March 31, 1997 amounted to $12.2 million, an increase of
$1.6 million from December 31, 1996. The increase was largely due to an
increase in receivables, which was proportionate to the higher sales levels in
the first quarter of 1997 relative to the last quarter of 1996. The ratio of
current assets to current liabilities at March 31, 1997 was 2.43 to 1,
compared to 2.41 to 1 at December 31, 1996.     
   
  Cash provided by operating activities totaled $1.2 million in the first
quarter of 1997, compared to $2.1 million in the same quarter of 1996, a
decrease of $.9 million. The decrease was due primarily to the reduced level
of earnings in the 1997 quarter, and an increase in overall working capital
requirements.     
   
  Cash used for investing activities totaled $.7 million in the first quarter
of 1997, compared to $.3 million in the first quarter of 1996. The total use
of cash for investing activities in both periods was for additions to
property, plant and equipment.     
   
  Financing activities used cash totaling $.3 million in the first quarter of
1997, compared to cash used totaling $1.1 million in the first quarter of
1996, representing the net cash transferred to AMETEK.     
   
 December 31, 1996 Compared to December 31, 1995     
   
  Working capital at December 31, 1996 amounted to $10.6 million, an increase
of $1.1 million from year-end 1995, largely due to the international water
filter business acquired in November 1995. Accounting for this acquisition was
completed in early 1996. The ratio of current assets to current liabilities at
December 31, 1996 was 2.41 to 1, compared to 2.82 to 1 at December 31, 1995.
    
  Cash provided by operating activities totaled $10.5 million in 1996,
compared to $7.0 million in 1995, an increase of $3.5 million. The increase
was due to higher earnings and lower overall working capital requirements.
 
  Cash used for investing activities totaled $2.3 million in 1996, compared to
$8.1 million in 1995. The primary use of cash in 1996 was for additions to
property, plant, and equipment, which totaled $2.2 million, compared to $2.4
million in 1995. Investing activities in 1995 also included a $5.7 million
cash outlay for the business acquisition mentioned above.
 
  Financing activities used cash totaling $7.9 million in 1996, representing
the remittance of operating cash to AMETEK. Net cash transfers from AMETEK
were $1.0 million in 1995.
 
NEW ACCOUNTING STANDARDS
 
  In the first quarter of 1996, the Water Filtration Business adopted
Financial Accounting Standards Board ("FASB") Statement No. 121, Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to be
Disposed of. Statement No. 121 establishes new accounting standards for
measuring the impairment of long-lived assets The adoption of this new
statement did not have any impact on the Water Filtration Business's combined
financial position or results of operations.
 
INTERNAL REINVESTMENT
 
 Capital Expenditures
   
  Capital expenditures were $.7 million for the three months ended March 31,
1997 and $2.2 million in 1996, essentially unchanged from $2.4 million in
1995. Approximately 71% of the expenditures for the first quarter of 1997 and
89% of the 1996 expenditures were for additional manufacturing equipment to
increase production efficiencies, and to expand production capacity. The Water
Filtration Business expects 1997 capital spending to exceed the 1996 level,
with continued emphasis on increasing production efficiencies and expansion,
primarily in the United States operation.

 Product Development and Engineering
   
  Product development and engineering expenses totaled $.4 million for the
first quarter of 1997, $1.5 million in 1996, $1.2 million in 1995, and $1.0
million in 1994. Such expenditures were directed toward the development of new
products and processes, and improvement of existing products and processes,
primarily related to the Water Filtration Business's U.S. operations.     
 
ENVIRONMENTAL MATTERS
   
  The Water Filtration Business is subject to environmental laws and
regulations regarding its operating locations and the environmental effects of
doing business at these sites. Currently, the Water Filtration Business is not
the subject of any government-mandated clean-ups at any of its operating
sites. Provisions for environmental clean-up and maintenance for the Water
Filtration Business were not material for 1996, 1995, and 1994. The Water
Filtration Business believes that, based on past experience and current
evaluations, any future environmental actions are not likely to have a
materially adverse effect on future combined results of operations, financial
position, or cash flows of the Water Filtration Business.     
 
IMPACT OF INFLATION AND FOREIGN OPERATIONS
 
  The Water Filtration Business attempts to minimize the impact of inflation
through cost reduction programs and by improving productivity. In general, the
Water Filtration Business believes programs are in place that are designed to
monitor the impact of inflation and to take necessary steps to minimize
inflation's effect on domestic and foreign operations.
 
  A portion of the Water Filtration Business's sales come from its foreign
operations. Although these operations are geographically dispersed, which
partially mitigates the risks associated with operating in particular
countries, the Water Filtration Business is subject to the usual risks
associated with international operations, including the exposure to
fluctuation in foreign currency exchange rates. The Water Filtration Business
believes that the economic risk associated with its foreign operations is
minimized because most of the products sold within the foreign markets are
sourced and distributed locally. In addition, except for a limited amount of
dividends and other payments to AMETEK, the Water Filtration Business
reinvests profits in the country where the profits are derived.

                     AND PLAN OF MERGER AND REORGANIZATION
 
  AMENDED AND RESTATED AGREEMENT AND PLAN OF MERGER AND REORGANIZATION, dated
as of February 5, 1997, by and among Culligan Water Technologies, Inc., a
Delaware corporation ("Parent"), Culligan Water Company, Inc., a Delaware
corporation and a wholly owned subsidiary of Parent ("Merger Sub"), Ametek,
Inc., a Delaware corporation (the "Company"), and Ametek Aerospace Products,
Inc., a Delaware corporation and indirect wholly owned subsidiary of the
Company ("Spinco").
 
  WHEREAS, the respective Boards of Directors of the Company, Parent and
Merger Sub deem it advisable and in the best interests of their respective
stockholders that Parent indirectly acquire the business of the Company's
Plymouth Products Division and the Retained Subsidiaries (as defined in the
Distribution Agreement(as defined below)) pursuant to the terms and conditions
set forth in this Agreement;
 
  WHEREAS, the Board of Directors of the Company has approved a contribution
and distribution agreement substantially in the form of Annex I hereto (the
"Distribution Agreement"), which will be entered into prior to the Effective
Time (as defined in Section 1.2), pursuant to which (a) all of the Company's
assets and liabilities, other than those used primarily in or associated
primarily with the Retained Business (as defined in the Distribution
Agreement), will be contributed to or assumed by Spinco (such contribution of
assets and assumption of liabilities, together with all other intercompany
transfers of assets and other actions described in Article 1 of the
Distribution Agreement, the "Contribution") and (b) shares of capital stock of
Spinco will be distributed (the "Distribution") on a pro rata basis to the
stockholders of the Company as provided in the Distribution Agreement in order
to divest the Company of the businesses and operations that Parent is
unwilling to acquire;
 
  WHEREAS, as set forth in Section 3.1 hereof, Parent, the Company and Spinco
are entering or will enter into (a) a trademark agreement substantially in the
form attached hereto as Annex II (the "Trademark Agreement"), (b) a tax
allocation agreement substantially in the form attached hereto as Annex III
(the "Tax Allocation Agreement"), (c) a transition services agreement
substantially in the form attached hereto as Annex IV (the "Transition

the form attached hereto as Annex V (the "Indemnification Agreement",
collectively, together with the Distribution Agreement, the Trademark
Agreement, the Tax Allocation Agreement, and the Transition Services
Agreement, the "Ancillary Agreements");
 
  WHEREAS, the respective Boards of Directors of Parent, Merger Sub and the
Company have determined that, following the Distribution, the merger of Merger
Sub with and into the Company (the "Merger"), with the Company surviving as a
wholly owned subsidiary of Parent, would be in the best interest of their
respective stockholders; and
 
  WHEREAS, for federal income tax purposes, it is intended that (a) the
Contribution followed by the Distribution will qualify as a tax-free
reorganization pursuant to Section 368(a)(1)(D) of the Internal Revenue Code
of 1986, as amended (the "Code"), (b) the Distribution will qualify as a tax-
free distribution pursuant to Section 355 of the Code, and (c) the Merger will
qualify as a tax-free reorganization pursuant to Section 368(a)(1)(B) of the
Code, and this Agreement is intended to be and is hereby adopted as a plan of
reorganization;
 
  WHEREAS, on February 5, 1997, Parent, Merger Sub, the Company and Spinco
entered into the original Agreement and Plan of Merger and Reorganization and
desire to amend and restate such original agreement in its entirety as of the
date of such original agreement.
 
  NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth herein, the
parties hereto, intending to be legally bound hereby, agree as follows:

                                  ARTICLE II
 
                           CONVERSION OF SECURITIES
 
  Section 2.1 Conversion of Capital Stock. As of the Effective Time, by virtue
of the Merger and without any action on the part of the holder of any shares
of common stock, par value $.01 per share, of the Company, including any
Company Rights (as such term is defined in Section 4.2 hereof) incident
thereto (collectively, the "Company Common Stock") or the holder of any
capital stock of Merger Sub:
 
    (a) Capital Stock of Merger Sub. Each issued and outstanding share of
  common stock, par value $1.00 per share, of Merger Sub (the "Merger Sub
  Common Stock") shall continue to be one issued and outstanding, fully paid
  and nonassessable share of Common Stock, par value $1.00 per share, of the
  Surviving Corporation.
 
    (b) Cancellation of Treasury Stock. All shares of Company Common Stock
  that are owned by the Company as treasury stock shall be cancelled and
  retired and shall cease to exist and no stock of Parent or other
  consideration shall be delivered in exchange therefor.
 
    (c) Exchange Ratio for Company Common Stock. Subject to Section 2.2(e),
  each issued and outstanding share of Company Common Stock (other than
  shares to be cancelled in accordance with Section 2.1(b)) shall be
  converted into the right to receive the number (rounded to the nearest one-
  thousandth of a share) (the "Exchange Ratio") of fully paid and
  nonassessable shares of Common Stock, par value $.01 per share, of Parent
  ("Parent Common Stock") determined by dividing (x) (A) the Net Equity Value
  (as defined below), by (B) $37.50, by (y) the number of shares of Company
  Common Stock outstanding at the Effective Time as certified to Parent by
  the Company's registrar and transfer agent. For purposes hereof, the "Net
  Equity Value" shall be an amount equal to (A) $155,000,000, minus (B) the
  amount of the Retained Debt (as defined in Section 4.11), minus (C) the
  product of 12.3 multiplied by the amount by which Adjusted EBIT (as defined
  below) for the Retained Business for the year ended December 31, 1996 as
  derived from the Interim Audited Financial Statements is less than
  $12,300,000. For purposes hereof, "Adjusted EBIT" shall mean earnings
  before interest and taxes as set forth in the income statement included in
  the Interim Audited Financial Statements, adjusted by Ernst & Young LLP (or
  another "big six" accounting firm selected by the Company) to reflect the
  financial results that would have been reported if prepared in accordance
  with the Reference Items (as defined in Section 3.4), together with a
  special report confirming that the preparation of the calculation of
  Adjusted EBIT is in accordance with this Agreement. All such shares of
  Company Common Stock, when so converted, shall no longer be outstanding and
  shall automatically be cancelled and retired and shall cease to exist, and
  each holder of a certificate representing any such shares shall cease to
  have any rights with respect thereto, except the right to receive the
  shares of Parent Common Stock and any cash in lieu of fractional shares of
  Parent Common Stock to be issued or paid in consideration therefor upon the
  surrender of such certificate in accordance with Section 2.2, without
  interest.
 
    (d) Adjustment of Exchange Ratio. If after the date hereof and prior to
  the Effective Time the outstanding shares of Parent Common Stock shall have
  been changed into a different number of shares or a different class, by
  reason of any stock dividend, subdivision, reclassification,
  recapitalization, split, combination or exchange of shares, the Exchange
  Ratio shall be correspondingly adjusted to reflect such stock dividend,
  subdivision, reclassification, recapitalization, split, combination or
  exchange of shares.
 
  Section 2.2 Exchange of Certificates.
 
  (a) Exchange Agent. Following the Closing Date, Parent shall make available
to a bank or trust company designated by Parent and reasonably acceptable to
the Company (the "Exchange Agent"), for the benefit of the holders of shares
of Company Common Stock, for exchange in accordance with this Article II,
through the Exchange Agent, certificates representing the shares of Parent
Common Stock issuable pursuant to Section 2.1 in exchange for outstanding
shares of Company Common Stock, which shares shall be deemed to be issued at
the Effective Time, together with cash to be paid in lieu of fractional shares
(such shares of Parent Common Stock, together with any dividends or
distributions with respect thereto contemplated by Section 2.2(c) and cash in
lieu of fractional shares, being hereinafter referred to as the "Exchange
Fund").
 
 
                                      A-3
<PAGE>
 
  (b) Exchange Procedures. As soon as practicable after the Effective Time,
the Surviving Corporation shall cause the Exchange Agent to mail to each
holder of record of a certificate or certificates which immediately prior to
the Effective Time represented outstanding shares of Company Common Stock (the
"Certificates") whose shares were converted pursuant to Section 2.1 into the
right to receive shares of Parent Common Stock (i) a letter of transmittal
(which shall be in such form and have such provisions as Parent and the
Company may reasonably specify) and (ii) instructions for use in effecting the
surrender of the Certificates in exchange for certificates representing shares
of Parent Common Stock. Upon surrender of a Certificate for cancellation to
the Exchange Agent or to such other agent or agents as may be appointed by
Parent, together with such letter of transmittal, duly executed, the holder of
such Certificate shall be entitled to receive in exchange therefor (A) a
certificate representing that number of whole shares of Parent Common Stock
which such holder has the right to receive pursuant to the provisions of this
Article II, and (B) cash in lieu of any fractional shares of Parent Common
Stock to which such holder is entitled pursuant to Section 2.2(e) hereof,
after giving effect to any required tax withholdings, and the Certificate so
surrendered shall forthwith be cancelled. In the event of a transfer of
ownership of Company Common Stock which is not registered in the transfer
records of the Company, a certificate representing the proper number of shares
of Parent Common Stock and cash in lieu of fractional shares of Parent Common
Stock may be issued to a transferee if the Certificate representing such
Company Common Stock is presented to the Exchange Agent, accompanied by all
documents required to evidence and effect such transfer and by evidence that
any applicable stock transfer taxes have been paid. Until surrendered as
contemplated by this Section 2.2, each Certificate shall be deemed at any time
after the Effective Time to represent only the right to receive upon such
surrender a certificate representing shares of Parent Common Stock and cash in
lieu of any fractional shares of Parent Common Stock as contemplated by this
Section 2.2.
 
  (c) Distributions with Respect to Unexchanged Shares. No dividends or other
distributions declared or made after the Effective Time with respect to Parent
Common Stock with a record date after the Effective Time shall be paid to the
holder of any unsurrendered Certificate with respect to the shares of Parent
Common Stock which such holder is entitled to receive upon the surrender
thereof in accordance with this Section 2.2 and no cash payment in lieu of
fractional shares shall be paid to any such holder pursuant to Section 2.2(e)
until the holder of record of such Certificate shall so surrender such
Certificate. Subject to the effect of applicable laws, following surrender of
any such Certificate, there shall be paid to the record holder of the
certificates representing whole shares of Parent Common Stock issued in
exchange therefor, without interest, (i) at the time of such surrender, the
amount of any cash payable in lieu of any fractional share of Parent Common
Stock to which such holder is entitled pursuant to Section 2.2(e) and the
amount of dividends or other distributions with a record date after the
Effective Time theretofore paid with respect to such whole shares of Parent
Common Stock, and (ii) at the appropriate payment date, the amount of
dividends or other distributions with a record date after the Effective Time
but prior to such surrender and a payment date subsequent to surrender payable
with respect to such whole shares of Parent Common Stock.
 
  (d) No Further Ownership Rights in Company Common Stock. All shares of
Parent Common Stock issued upon the surrender for exchange of shares of
Company Common Stock in accordance with the terms hereof (including any cash
paid pursuant to Section 2.2(c) or 2.2(e)) shall be deemed to have been issued
in full satisfaction of all rights pertaining to such shares of Company Common
Stock, and there shall be no further registration of transfers on the stock
transfer books of the Surviving Corporation of the shares of Company Common
Stock which were outstanding immediately prior to the Effective Time. If,
after the Effective Time, Certificates are presented to the Surviving
Corporation for any reason, they shall be cancelled and exchanged as provided
in this Article II.
 
  (e) No Fractional Shares. No certificate or scrip representing fractional
shares of Parent Common Stock shall be issued upon the surrender for exchange
of Certificates, and such fractional share interests will not entitle the
owner thereof to vote or to any rights of a stockholder of Parent. In lieu of
any such fractional shares, each holder of Company Common Stock who would
otherwise have been entitled to a fraction of a share of Parent Common Stock
upon surrender of certificates for exchange will be entitled to receive a cash
payment in lieu of such fractional share in an amount equal to such fractional
interest multiplied by the Average Parent Share Price
 
                                      A-4
<PAGE>
 
(as defined). The "Average Parent Share Price" shall be equal to the average
of the closing prices of the Parent Common Stock on the New York Stock
Exchange (the "NYSE") Composite Transactions Reporting System, as reported in
The Wall Street Journal, for the ten (10) trading days ending on the second
trading day immediately prior to the Effective Time.
 
  (f) Termination of Exchange Fund. Any portion of the Exchange Fund which
remains undistributed to the stockholders of the Company for six months after
the Effective Time shall be delivered to Parent, upon demand, and any
stockholders of the Company who have not theretofore complied with this
Article II shall, subject to any applicable abandoned property, escheat or
similar law, thereafter look only to Parent for the shares of Parent Common
Stock, any cash in lieu of fractional shares of Parent Common Stock and any
dividends or distributions with respect to Parent Common Stock to which they
are entitled pursuant to this Article II.
 
  (g) No Liability. None of Parent, Merger Sub, the Company or Spinco shall be
liable to any holder of shares of Company Common Stock or Parent Common Stock,
as the case may be, for such shares (or dividends or distributions with
respect thereto) or cash for payment in lieu of fractional shares delivered to
a public official pursuant to any applicable abandoned property, escheat or
similar law.

                   CERTAIN PRE- AND POST-MERGER TRANSACTIONS
 
  Section 3.1 Ancillary Agreements. Prior to the Distribution, the Company
will (a) execute and deliver the Distribution Agreement, the Trademark
Agreement, the Tax Allocation Agreement, the Transition Services Agreement,
and the Indemnification Agreement and (b) cause Spinco to execute and deliver
the Distribution Agreement, the Trademark Agreement, the Transition Services
Agreement, the Tax Allocation Agreement, and the Indemnification Agreement.
Prior to the Distribution, Parent will execute and deliver the Indemnification
Agreement.
 
  Section 3.2 Contribution of Assets and Assumption of
Liabilities. Immediately prior to the Distribution and pursuant to the terms
of the Distribution Agreement, the Company and Spinco will consummate the
Contribution.
 
  Section 3.3 Distribution. At least one day prior to the Effective Time, and
pursuant to the terms of Article 3 of the Distribution Agreement, the Company
will cause the Contribution to be consummated and effect the Distribution.
 
  Section 3.4 Audited Closing Balance Sheet. No later than 45 days after the
Closing Date, Spinco shall deliver to Parent an audited consolidated balance
sheet for the Retained Business as of the Closing Date after giving effect to
the Distribution (but not the Merger), which shall be audited by Spinco's
independent public accountants in accordance with United States generally
accepted accounting principles (the "Audited Closing Balance Sheet"). The
Audited Closing Balance Sheet shall be prepared in accordance with United
States generally accepted accounting principles ("GAAP") and, to the extent
consistent with GAAP, on a basis consistent with the Retained Business
Financial Statements (as defined in Section 4.7(a)). Together with the
delivery of the Audited Closing Balance Sheet, Spinco shall deliver an
adjusted balance sheet of the Retained Business as of the Closing Date (the
"Adjusted Closing Balance Sheet") which shall adjust the Audited Closing
Balance Sheet (x) to reflect the financial position that would have been
reported if prepared in accordance with the items (and accounting principles)
set forth on Schedule 3.4 and (y) to exclude any cash paid to the Company by
Spinco (or retained by the Company) pursuant to Section 1.5(e) of the
Distribution Agreement to compensate Parent for the Special Offer Amount (as
defined in the Distribution Agreement) and for any unexercised options held by
any Retained Employees (as defined in Section 7.8(a)) following the Effective
Time (clauses (x) and (y) being referred to as the "Reference Items").
Notwithstanding the foregoing, in the event that a liability or accrual
appears in the Adjusted Closing Balance Sheet which was not identified as a
Reference Item and which was not reflected on the balance sheet included in
the Retained Business Financial Statements, no adjustment
 
                                      A-5
<PAGE>
 
shall be made pursuant to this Section 3.4 to the extent such liability or
accrual is an Assumed Liability (as defined in the Distribution Agreement). To
the extent that the Adjusted Net Worth (as defined below) of the Retained
Business as calculated from the Adjusted Closing Balance Sheet is less than
$31,745,000, then Spinco shall pay to the Company in cash the amount of such
shortfall in Adjusted Net Worth within thirty days of the delivery of the
Adjusted Closing Balance Sheet (or, if later, upon resolution of the matters
set forth in the Notice (as defined below)). To the extent that the Adjusted
Net Worth of the Retained Business as calculated from the Adjusted Closing
Balance Sheet is more than $31,745,000, then the Company shall pay Spinco in
cash the amount of such excess up to a maximum amount of $2,000,000 within
thirty days of the delivery of the Adjusted Closing Balance Sheet (or, if
later, upon resolution of the matters set forth in the Notice). For purposes
hereof, the term "Adjusted Net Worth" shall mean the amount by which
consolidated assets exceed consolidated liabilities, in each instance as set
forth on the Adjusted Closing Balance Sheet. Any payment required to be made
pursuant to this Section 3.4 shall not be affected by or offset against any
adjustment to or reduction of Net Equity Value pursuant to Section 2.1(c)
hereof. Spinco agrees that representatives of Parent shall be given access to
all work papers, books, records and other information related to the
preparation of the Adjusted Closing Balance Sheet. Should Parent determine
that the Audited Closing Balance Sheet is not in accordance with this
Agreement, Parent shall so notify Spinco within 30 days of receipt of the
Adjusted Closing Balance Sheet of those items on which Parent is not in
agreement (the "Notice"), including the amount by which Parent believes the
Adjusted Net Worth as calculated from the Adjusted Closing Balance Sheet is
overstated (collectively, the "Parent Adjustment"). The parties shall then
promptly designate representatives who shall meet for the purpose of resolving
the differences between the parties. If such differences have not been
resolved within 30 days after receipt by Spinco of the Notice, then Parent and
Spinco shall select and retain an independent public accounting firm mutually
agreeable to the parties (or, if they cannot agree on a mutually acceptable
firm, they shall cause their respective accounting firms to select such firm)
(the "Third Party Firm") to resolve such differences. The Third Party Firm
shall be requested to render a decision within thirty days of its selection.
The decision of the Third Party Firm shall be final and binding on both
parties. The fees and expenses of the Third Party Firm shall be (i) paid by
Parent if less than 25% of the dollar amount of the Parent Adjustment is
required to be made or (ii) paid by Spinco if more than 75% of the dollar
amount of the Parent Adjustment is required to be made or (iii) shared equally
by Parent and Spinco if 25% or more but less than 75% of the dollar amount of
the Parent Adjustment is required to be made.

                       REPRESENTATIONS AND WARRANTIES OF
                            THE COMPANY AND SPINCO

  Section 4.1 Organization. Each of the Company and its Subsidiaries is a
corporation duly organized, validly existing and in good standing under the
laws of the jurisdiction of its incorporation and has all requisite corporate
power and authority to own, lease and operate its properties and to carry on
its business as now being conducted, except where the failure to be so
organized, existing and in good standing or to have such power and authority
would not have a material adverse effect on the Retained Business. The Company
and each of its Subsidiaries is duly qualified or licensed to do business and
in good standing in each jurisdiction in which the property owned, leased or
operated by it or the nature of the business conducted by it makes such
qualification or licensing necessary, except where the failure to be so duly
qualified or licensed and in good standing would not in the aggregate have a
material adverse effect on the Retained Business or on the ability of the
Company to consummate the transactions contemplated hereby. True, accurate and
complete copies of the Company's and each of its Subsidiaries' Certificate of
Incorporation and Bylaws (or similar organizational documents), including all
amendments thereto, have heretofore been delivered to Parent. Such Certificate
of Incorporation and By-laws (or similar organizational document) are in full
force and effect and neither the Company nor any of the Retained Subsidiaries
is in violation of any provision of its charter, by-laws or comparable

capital stock of each of the Retained Subsidiaries is duly authorized, validly
issued, fully paid, nonassessable and free of any preemptive rights in respect
thereto and such shares are owned by the Company or by a Subsidiary (as
defined below) of the Company free and clear of any lien, claim, option,
charge, security interest, limitation on voting rights and encumbrance of any
kind.

power and authority to execute and deliver this Agreement and the Ancillary
Agreements (to the extent a party thereto) and to consummate the transactions
contemplated hereby and thereby (other than the approval and adoption of this
Agreement and the Ancillary Agreements by the affirmative vote of the holders
of Company Common Stock entitled to cast at least a majority of the total

the extent a party thereto) and constitutes or (to the extent such agreement

  Section 4.7 Retained Business.
 
  (a) Attached hereto as Exhibit 4.7 is an unaudited pro forma consolidated
balance sheet of the Retained Company and the Retained Subsidiaries at
December 31, 1996 (including the notes thereto, the "Retained Business Balance
Sheet") and unaudited pro forma consolidated statement of income for the
Retained Company and the Retained Subsidiaries for the year then ended
(collectively with the Retained Business Balance Sheet,
 
                                      A-9
<PAGE>
 
the "Retained Business Financial Statements"). The Retained Business Financial
Statements have been prepared on a pro forma basis giving effect to the
Distribution in accordance with GAAP (except as expressly stated therein) on a
basis consistent with the Company Financial Statements referred to in Section
4.5, and fairly present in all material respects (subject, in the case of such
unaudited statements, to normal, recurring audit adjustments which will not be

Retained Subsidiaries as at the date thereof after giving effect to the
Distribution (assuming the Distribution occurred on December 31, 1996), and
the results of its operations for the period then ended, after giving effect
to the Distribution (assuming the Distribution occurred on January 1, 1996).
 
  (b) As of December 31, 1996, the Company or the Retained Subsidiaries
directly or indirectly owned or had a valid leasehold interest in the assets
reflected on the Retained Business Balance Sheet, free and clear of any liens,
claims, encumbrances or other rights of third parties, except as may be
reflected in the Retained Business Balance Sheet or as may be set forth
therein or in the Company Disclosure Schedule or for any non-consensual liens
or defects in title which do not, individually or in the aggregate, interfere
with the conduct of the Retained Business as currently conducted or the
utilization of the Retained Assets. The Retained Business includes all of the
assets or rights that are material to the Retained Company and the Retained
Subsidiaries. All of the buildings and other material tangible personal
property owned or leased by the Company and its Subsidiaries that are included
in the Retained Business are in good working condition (normal wear and tear
excepted) and are suitable in all material respects for the purposes for which
they are being used. The Company has reasonable relationships will all
customers, employees and others having business dealings with the Retained
Business.
 
  (c) At the Effective Time, except as contemplated by the Distribution
Agreement, neither Spinco nor any of its Subsidiaries will use in the conduct
of its business or own or have rights to use any assets or property, whether
tangible, intangible or mixed, which are also primarily used in the conduct of
the Retained Business. Except as set forth in the Company Disclosure Schedule,
at the Effective Time neither Spinco nor any of its Subsidiaries will be a
party to any material agreement, arrangement or understanding with the
Retained Company or any of the Retained Subsidiaries (other than the Ancillary
Agreements and any agreements contemplated by the Distribution Agreement).
 
  Section 4.8 Litigation. Except as set forth in the Company Disclosure
Schedule, there is no suit, claim, action, proceeding or investigation pending
or, to the best knowledge of the Company, threatened, against the Company or
any of its Subsidiaries before any Governmental Entity which, (i) individually
or in the aggregate, is reasonably likely to have a material adverse effect on
the Retained Company and the Retained Subsidiaries taken as a whole or (ii)
exists on the date hereof and in which the amount claimed or cost of
compliance with the action sought is in excess of $100,000 for the Retained
Company and the Retained Subsidiaries or $1,000,000 in any other case. Except
as disclosed in Section 4.8 of the Company Disclosure Schedule, neither the
Company nor any of its Subsidiaries is subject to any outstanding order, writ,
injunction or decree which, insofar as can be reasonably foreseen,
individually or in the aggregate, would have or be reasonably expected to have
a material adverse effect on the Retained Company or a material adverse effect
on the ability of the Company or Spinco to consummate the transactions
contemplated hereby or by the Ancillary Agreements.
 
  Section 4.9 Opinion of Financial Advisor. The Company has received the oral
opinion of Goldman, Sachs & Co., to be confirmed in writing, to the effect
that, as of such date, the consideration to be received in the Merger by the
Company's stockholders is fair to the Company's stockholders, a copy of which
opinion will be delivered to Parent.

compensation, pension, retirement, profit-sharing, thrift, savings, employee
stock ownership, stock bonus, stock purchase, restricted stock and stock
option plans, all employment or severance contracts, other material employee
benefit plans and any applicable "change of control" or similar provisions in
any plan, contract or arrangement which cover the
 
                                     A-10
<PAGE>
 
Retained Employees or former employees of the Retained Business and which are
maintained or contributed to by the Company, Spinco or any entity which may be
deemed a single employer with the Company under Section 4001 of Employee
Retirement Income Security Act of 1974, as amended ("ERISA"), or Section 414
of the Code (an "ERISA Affiliate") (regardless of whether they are funded or
unfunded or foreign or domestic), including, but not limited to, "employee
benefit plans" within the meaning of Section 3(3) of the ERISA (collectively,
the "Retained Employee Compensation and Benefit Plans"). True and complete
copies of all the Retained Employee Compensation and Benefit Plans, including
any trust instruments and/or insurance contracts, if any, forming a part of
any such plans, and all amendments thereto; current summary plan descriptions;
where applicable, the most current determination letter received from the
Internal Revenue Service (the "Service") and most recent determination letter
application, and where applicable, annual reports, financial statements and
actuarial reports for the last three plan years, which fairly and accurately
reflect the financial condition of the plans have been made available to
Parent.
 
  (b) All of the Retained Employee Compensation and Benefit Plans are in
material compliance with all applicable laws, including without limitation,
ERISA and the Code. Each Retained Employee Compensation and Benefit Plan which
is an "employee pension benefit plan" within the meaning of Section 3(2) of
ERISA ("Retained Employee Pension Plan") and which is intended to be qualified
under Section 401(a) of the Code, has received a favorable determination
letter from the Service, and the Company is not aware of any circumstances
likely to result in revocation of any such favorable determination letter.
Neither the Company nor any ERISA Affiliate has engaged in a transaction with
respect to any Compensation and Benefit Plan that, assuming the taxable period
of such transaction expired as of the date hereof, could subject the Company
or any ERISA Affiliate to a tax or penalty imposed by either Sections 4975 or
4976 of the Code or Section 502(i) of ERISA in an amount which would have a
material adverse effect on the Retained Business. Neither the Company nor any
ERISA Affiliate has contributed or been required to contribute to any
Multiemployer Plan (as defined in ERISA).
 
  (c) No liability under Title IV of ERISA has been or is expected to be
incurred by the Company or any ERISA Affiliate with respect to any ongoing,
frozen or terminated Retained Employee Compensation and Benefit Plan,
currently or formerly maintained by any of them.
 
  (d) All contributions required to be made or accrued as of December 31, 1996
under the terms of any Retained Business Compensation and Benefit Plan have
been timely made or have been reflected on the Audited Closing Balance Sheet.
No Retained Employee Pension Plan has incurred an "accumulated funding
deficiency" (whether or not waived) within the meaning of Section 412 of the
Code or Section 302 of ERISA. Neither the Company nor any ERISA Affiliate has
provided, or is required to provide, security to any Retained Employee Pension
Plan pursuant to Section 401(a)(29) of the Code.
 
  (e) No Retained Employee Compensation and Benefit Plan provides benefits,
including without limitation death or medical benefits (whether or not
insured), with respect to current or former employees of the Retained Business
beyond their retirement or other termination of service (other than (i)
coverage mandated by applicable law or (ii) death benefits or retirement
benefits under any "employee pension plan," as that term is defined in section
3(2) of ERISA).
 
  (f) All Retained Employee Compensation and Benefit Plans covering Company
Employees located outside of the United States comply in all material respects

401(k) Plan (as adopted and assumed by Spinco) of the account balances of the
Retained Employees (including, if applicable, the outstanding balances of any
participant loans to the extent that the transfer of such loans will not cause
a taxable distribution to the participant subject to each such Retained
Employee executing a loan agreement with Parent's 401(k)).
 
  (e) Parent shall provide Spinco with an annual statement of the compensation
earned by each Retained Employee from Parent or its Subsidiaries (or any
successor thereto or affiliate thereof) after the Effective Time. Parent shall
also notify Spinco, within thirty days of the retirement, death, disability or
other termination of employment of any Retained Employee from Parent or its

Acquisition Transaction (as defined below); provided that nothing shall
prohibit the Company from (i) furnishing information to, or entering into
discussions or negotiations with, any person or entity that makes an
unsolicited proposal with respect to a Company Acquisition Transaction (as
defined below), if, and only to the extent that, (A) the Board of Directors of
the Company, after consultation with and based upon the advice of independent
legal counsel, determines in good faith that such action is necessary for the
Board of Directors of the Company to comply with its fiduciary duties to
stockholders under applicable law, and (B) prior to furnishing such
information to, or entering into discussions or negotiations with, such person
or entity, the Company provides written notice to Parent stating that it is

such person or entity; or (ii) complying with Rule 14e-2 promulgated under the

Business Acquisition Transaction shall mean an Acquisition Transaction which
relates to the Retained Business (a "Retained Business Acquisition
Transaction").

Agreement, whether or not the Merger and the transactions contemplated hereby
shall be paid by the party incurring such expenses; provided, however, that
the Company and Parent shall each pay one-half of the printing, mailing and
filing costs incurred in connection with the S-4, the Distribution
Registration Statement and the Proxy Statement.

  (b) So long as Parent shall not have materially breached its obligations
under this Agreement, the Company will pay Parent, in immediately available
funds, $5,000,000 (promptly, but in no event later than thirty days after such
amount becomes due), if within twelve months following the termination of this
Agreement pursuant to Section 9.1(c)(ii) or (iii) or Section 9.1(d)(ii) the
Company shall enter into an agreement, arrangement or understanding providing
for an Acquisition Transaction. Notwithstanding the foregoing, the Company

expenses incurred by Parent in connection with the Merger and the
Distribution, promptly but in no event later than 30 business days after being
provided with a statement of such expenses together with documentation
satisfactory to the Company substantiating the incurrence of such expenses,
after the termination of this Agreement pursuant to Section 9.1(c) (other than

Section 4.15(xiii)) or Section 9.1(d)(ii). Parent will pay in immediately
available funds, the out-of-pocket expenses incurred by the Company in

cause each of those persons who may be deemed to be "affiliates" of the
Company as that term is used in paragraphs (c) and (d) of Rule 145 under the
Securities Act (the "Affiliates") and who will become the beneficial owners of
Parent Common Stock pursuant to the Merger to deliver to Parent on or prior to
the Closing Date a written "affiliates' agreement" in customary form. If any
Affiliate refuses to provide such agreement, Parent may place appropriate
legends on the certificates evidencing the shares of Parent Common Stock to be
received by such Affiliate pursuant to the terms of this Agreement and to
issue appropriate stop transfer instructions to the transfer agent for shares
of Parent Common Stock to the effect that the shares of Parent Common Stock
received by such Affiliate pursuant to this Agreement only may be sold,
transferred or otherwise conveyed, (x) pursuant to an effective registration
statement under the Securities Act, (y) in compliance with Rule 145
promulgated under the Securities Act, or (z) pursuant to another exemption
under the Securities Act.
 
  Section 7.14 Notification of Certain Matters. The Company shall give prompt
notice to Parent, and Parent shall give prompt notice to the Company, of (a)
the occurrence, or non-occurrence, of any event the occurrence, or non-
occurrence, of which would be likely to cause (i) any representation or
warranty contained in this Agreement to be untrue or inaccurate or (ii) any
covenant, condition or agreement contained in this Agreement not to be
complied with or satisfied and (b) any failure of the Company or Parent, as
the case may be, to comply with or satisfy any covenant, condition or
agreement to be complied with or satisfied by it hereunder; provided, however,
that the delivery of any notice pursuant to this Section 7.14 shall not limit
or otherwise affect the remedies available hereunder to the party receiving
such notice.
 
  Section 7.15 Tax-Free Nature of Transactions. Each party agrees to report
the Contribution as a tax-free reorganization pursuant to Section 368(a)(1)(D)
of the Code, the Distribution as a tax-free distribution pursuant to Section
355 of the Code and the Merger as a tax-free reorganization pursuant to
Section 368(a)(1)(B) of the Code on all Tax Returns and other filings, and
take no position inconsistent therewith in any audit or administrative or
judicial proceeding or otherwise. The parties shall not, and shall not permit
any of their respective Subsidiaries to, take or cause or permit to be taken,
any action, or allow to exist any condition, that would, disqualify the
Contribution as a tax-free reorganization pursuant to Section 368(a)(1)(D),
disqualify the Distribution as a tax-free distribution pursuant to Section 355
of the Code or disqualify the Merger as a reorganization pursuant to Section
368(a)(1)(B) of the Code.
 
  Section 7.16 Indebtedness. Except as reflected on the Retained Business
Balance Sheet, the Company agrees that immediately prior to the Effective
Time, after giving effect to the Contribution and the other transactions
contemplated by the Ancillary Agreements, there will not be outstanding any
indebtedness for borrowed money, or any guarantees in respect of any
indebtedness for borrowed money of any third party, in respect of which the
Retained Company or the Retained Subsidiaries is obligated, other than the
Retained Debt.
 
  Section 7.17 Internal Revenue Service Ruling. As promptly as practicable
following the date hereof, the Company and Parent shall prepare and submit to
the IRS a request for a private letter ruling to the effect that (i)
 
                                     A-27
<PAGE>
 
the Contribution followed by the Distribution will qualify as a tax-free
reorganization pursuant to Section 368(a)(1)(D) of the Code, (ii) the
Distribution will qualify as a tax-free distribution pursuant to 355 of the
Code and (iii) the Merger will qualify as a tax-free reorganization pursuant
to Section 368(a)(1)(B) of the Code. The initial ruling request and any
supplements or materials submitted to the Service relating thereto (each, an
"IRS Submission") shall be true and correct in all material respects and all
relevant and material facts relating to the requested rulings shall be
disclosed to the Service. The Company shall provide Parent with a reasonable
opportunity to review and comment on each IRS Submission prior to the filing
of such IRS Submission with the IRS and no IRS Submission shall be filed with
the IRS unless the Company and Parent shall have agreed as to the contents of
such IRS Submission prior to such filing. The Company shall promptly provide
Parent with copies of each IRS Submission as filed with the Service. Neither
the Company nor the Company's representatives shall conduct any
communications, other than non-substantive administrative communications, with
the Service concerning such private letter ruling, including meetings or
conferences with Service personnel, whether telephonically or in person or
otherwise, without the participation of (or express waiver of such
participation by) Parent or Parent's representatives. Parent shall reasonably
cooperate in good faith with the Company in seeking to obtain such private
letter ruling.

         AMENDED AND RESTATED CONTRIBUTION AND DISTRIBUTION AGREEMENT
 
  AMENDED AND RESTATED CONTRIBUTION AND DISTRIBUTION AGREEMENT, dated as of
February 5, 1997 (this "Agreement") between AMETEK, INC., a Delaware
corporation (the "Company"), and AMETEK AEROSPACE PRODUCTS, INC., a Delaware
corporation and a wholly owned subsidiary of the Company ("Spinco").
 
                                  WITNESSETH
 
  WHEREAS, the Company operates various lines of business through divisions
and/or subsidiaries (the "Businesses");
 
  WHEREAS, one such line of business consists of the Company's Plymouth
Products Division and the Company's Ametek Filters Limited, APIC International
S.A., and AFIMO SAM subsidiaries (collectively, the "Retained Business");
 
  WHEREAS, the Company, Spinco, Culligan Water Technologies Inc., a Delaware
corporation ("Culligan"), and Culligan Water Company, Inc., a Delaware
corporation and a wholly owned subsidiary of Culligan ("Merger Sub"), are
parties to an Amended and Restated Agreement and Plan of Merger and
Reorganization dated the date hereof (the "Merger Agreement"), providing for
the merger of Merger Sub and the Company (the "Merger");
 
  WHEREAS, it is a condition precedent to the Merger that the Company spin-off
Spinco to the Company's stockholders (the "Spin-off") and the Board of
Directors of the Company has determined that it is appropriate and desirable
that the Company contribute (as defined below) to Spinco all of its assets and
businesses other than the Retained Assets (as defined below) and that Spinco
assume the liabilities of the Company other than the Retained Liabilities (as
defined below), all as more particularly set forth below;
 
  WHEREAS, it is further contemplated in the Merger Agreement that following
such contribution of assets and prior to the Effective Time (as defined in the
Merger Agreement), the Company effectuate the Spin-off by distributing as a
dividend to the holders of shares of common stock, par value $.01 per share,
of the Company (the "Company Common Stock") all of the outstanding shares of
common stock, par value $.01 per share, of Spinco (the "Spinco Common Stock"),
so that following the Spin-off, the Company will own no shares of capital
stock of Spinco (such distribution prior to the Effective Time is hereinafter
referred to as the "Distribution");
 
  WHEREAS, it is the intention of the parties that following the Distribution,
Spinco will continue all of the Company's Businesses other than the Retained
Business (collectively, the "Spinco Businesses") and the Company will retain
the Retained Assets, the Retained Employees (as defined in the Merger
Agreement) and the Retained Liabilities;
 
  WHEREAS, the purpose of the Distribution is to make possible the Merger by
divesting the Company of the businesses and operations to be conducted by
Spinco, which Culligan is unwilling to acquire; and
 
  WHEREAS, the parties intend that the transactions contemplated hereby and
under the Merger Agreement qualify as a tax-free spin-off and reorganization
under Sections 368(a)(1)(D), 355 and 368(a)(1)(B) of the Internal Revenue Code
of 1986, as amended (the "Code");
 
  WHEREAS, on February 5, 1997, the Company and Spinco entered into the
original Agreement and desire to amend and restate such Agreement in its
entirety as of the date of such original Agreement;
 
 
                                     B1-1

  in the Contributed Assets and provided further that if Spinco holds any
  insurance (excluding self-insurance) covering any such existing claim, the
  Company shall be entitled to the benefits thereof to the extent that such
  coverage can be enforced for the Company's benefit but subject to the
  conditions that Spinco's experience ratings or premium costs not be
  adversely affected by enforcement, that Spinco shall not be required to
  make any expenditure in connection with such enforcement and that all cost
  of such enforcement shall be for the Company's account.
 
    (n) to the extent transferable, all rights to contribution protection and
  covenants not to sue granted to the Company by third parties in connection
  with environmental matters being assumed by Spinco;
 
    (o) all proprietary or confidential business or technical information,
  records and policy statements of the Company, which relate generally to the
  Company or the Spinco Businesses rather than primarily to the Retained
  Business, such as accounting procedures, instructions, organizational
  manuals, strategic plans and other documents or materials of a general
  nature, except that the Company shall retain non-exclusive rights to use
  such materials which are presently used in the Retained Business;
 
    (p) all proprietary or confidential business or technical information,
  records and policy statements which primarily relate to any Spinco
  Business;

  included in the Retained Assets;
 
all as the same shall exist on the Distribution Date, subject only to the
disposition of any assets by the Company prior to the Distribution Date,
provided that if any Contributed Asset is also material to the Retained
Business, the parties shall, on the Distribution Date, enter into such
reasonable arrangements, including licensing, sublicensing, leasing or
subleasing, as shall enable the Company to continue to use such asset in the
Retained Business perpetually and at no cost. No contract or agreement which
is by law not assignable without the consent of any party thereto shall be
deemed assigned pursuant to this Agreement unless and until such consent or a
waiver therefrom is given. The Company agrees to use commercially reasonable
efforts to obtain prior to the Distribution Date all such consents and
waivers. If any such consent or waiver is not obtained before the Distribution
Date and the Distribution is nevertheless consummated, the Company agrees to
continue to use its commercially reasonable efforts to obtain all such
consents or waivers as have not been obtained prior to such date and further
agrees to cooperate with Spinco after such date in any reasonable arrangement
(such as subcontracting, sublicensing or subleasing) designed to provide for
Spinco, on terms at least as favorable as those to which the Company is
entitled, the benefits under the applicable contract or agreement, including,
without limitation, enforcement, at the cost and for the benefit of Spinco, of
any and all rights of the Company against any other party thereto arising out
of the breach or cancellation thereof by such party; provided that Spinco will
hold the Company harmless with respect to such contracts or arrangements
relating thereto.

Date. Effective as of the Distribution Date, the Retained Employees shall not
be eligible to make any contributions, or have the Company make any
contributions on their behalf, to the Company's 401(k) Plan. As soon as
practicable on or after the Effective Time (as defined in the Merger
Agreement) of the Merger, Spinco shall cause the Company's 401(k) Plan to
initiate a direct plan-to-plan transfer to Culligan's 401(k) Plan of the
account balances of the Retained Employees (including, if applicable, any
outstanding participant loans to the extent that the transfer of such loans
will not cause a taxable distribution to the participant, subject to each such
Retained Employee's executing a loan agreement for the balance of such loans
with Culligan's 401(k) Plan) under the Company's 401(k) Plan; provided that
Culligan's 401(k) Plan, shall have agreed to accept such transfer.
 
  (c) Welfare Plans. Effective as of the Distribution Date, Spinco shall
assume all severance, vacation, medical, disability, life insurance, split-
dollar and any other welfare benefit plans covering employees (and their
spouses and dependents), other than the Retained Employees, and their spouses
or dependents, (including any insurance policies maintained under or in
connection with welfare benefit plans or split-dollar arrangements being
assumed by Spinco) or, in the event any such arrangement or plan covers both
Retained Employees and Spinco Employees, Spinco shall only assume the portion
of such arrangement or plan relating to the Spinco Employees and, in either
case, Spinco shall be liable for all benefits thereunder with respect to the
Spinco Employees (and their spouses and dependents), including benefits for
covered expenses incurred, and benefits accrued, prior to the Distribution
Date; provided that Spinco shall not apply any pre-existing condition
exclusion or limitation to a Spinco Employee unless it applied immediately
prior to the Distribution Date. Prior to the Distribution Date, the Company
shall use its best efforts to obtain the consent of any life insurance or
disability insurance carrier of any policy covering both Retained Employees
and Spinco Employees to split the policy into two separate policies, one
covering only Retained Employees ("Retained Employees Welfare Benefit
Insurance Policies") and the other covering only Spinco Employees ("Spinco
Employees Welfare Benefit Insurance Policies"); in the event that an insurance
carrier agrees to the splitting of existing insurance policies as aforesaid,
then, effective as of the Distribution Date, Spinco shall only assume the
Spinco Employee Welfare Benefit Insurance Policies (and not the Retained
Employees Welfare Benefit Insurance Policies). Effective as of the
Distribution Date, Spinco will also assume liability (i) for those uninsured
health, dental and vision benefits incurred by Retained Employees prior to the
Distribution Date but only if claims therefor have been incurred prior to such
Distribution Date and (ii) for those benefits incurred by Retained Employees
prior to the Distribution Date which are covered by insurance policies
assigned to and assumed by Spinco. Effective as of the Distribution Date,
Spinco shall also be liable for any retiree medical benefits to retired
Company employees and their dependents, pursuant to the retiree medical plans
or policies of the Company.
 
  (d) Defined Benefit Plans. Effective as of the Distribution Date, Spinco
shall adopt the Company's defined benefit pension plans other than the
Retained Hourly Pension Plan (the "Spinco Pension Plans"), subject to the
provision that each employee of the Company shall be given credit, for all
purposes under said Plans, for service before the Distribution Date recognized
by said Plans before the Distribution Date. Spinco shall, as of the date of
its adoption of the Spinco Pension Plans, assume all liabilities for benefits
thereunder, regardless of whether such benefits accrued before or after the
Distribution Date, and shall be responsible for all funding obligations
thereunder, regardless of whether such funding obligations relate to services
performed before or after the Distribution Date. Effective as of the
Distribution Date, Spinco shall assume the Company's Group Pension Trust, and
any individual or sub-trust thereunder, except for any trust maintained solely
in connection with the Retained Hourly Pension Plan. As soon as practicable on
or after the Distribution Date, Spinco shall cause the assets of the Retained
Hourly Pension Plan which are held in the Group Pension Trust to be
transferred to such trustee or trustees or other funding agencies as shall be
designated by the Company under the Retained Hourly Pension Plan; pending said
transfer of assets, Spinco shall cause all payments to retirees and
beneficiaries under the Retained Hourly Pension Plan to continue to be made
from the Group Pension Trust and shall charge any and all such payments, and
the related expenses, if any, to the interest of the Retained Hourly Pension
Plan
 
                                     B1-7
<PAGE>
 
thereunder. Spinco shall cause the Company's Salaried Pension Plan to be
amended to provide that Retained Employees shall not be considered terminated
until they terminate employment with the Company, at which time they shall be
entitled to benefits in accordance with the terms of the Company's Salaried
Pension Plan (which shall have been adopted by Spinco) based upon their
benefits accrued as of the Distribution Date; provided, however, that each
Retained Employee's final average annual compensation shall be determined by
treating compensation earned with the Company after the Distribution Date as
if it were compensation earned with Spinco, but the Retained Employee's annual
compensation for each year after 1996 which shall be recognized for purposes
of the Company's Salaried Pension Plan will be limited to an amount equal to
such Retained Employee's 1996 plan compensation, increased by 5% per annum,
compounded annually; and, provided further, that periods of service with the
Company after the Distribution Date shall be treated as service with Spinco
for purposes of determining a Retained Employee's vesting and eligibility for
early retirement, disability and pre-retirement death benefits under the
Salaried Pension Plan (but not for the purpose of determining the benefit
amount thereof).
 
  (e) Stock Option and Stock Incentive Plans. Prior to the Distribution Date,
Spinco shall adopt one or more stock option, stock incentive or similar plans
or arrangements for Spinco's eligible employees and directors, which plans or
arrangements shall be subject to approval by the Company, as the sole
stockholder of Spinco, prior to the Distribution Date. Effective as of the
Distribution Date, all outstanding options to purchase Company Common Stock
held by employees other than the Retained Employees, whether or not such
options are then exercisable, shall be assumed by Spinco and shall be
exercisable upon the same terms and conditions as under the applicable option
and the Company stock option or stock incentive plan, except that each such
option shall be exercisable for a whole number of shares of Spinco Common
Stock and for a per share exercise price such that the aggregate spread
between the value of the Company Common Stock and the exercise price
immediately before the Distribution Date, and the per share ratio between the
value of the Company Common Stock and the exercise price immediately before
the Distribution Date, shall be preserved, in accordance with Treasury
Regulations (S)1.425-1 and in such a manner as will not cause such assumption
to be considered a "modification" of the option under said section (or would
not cause such assumption to be a modification of the option if such option
were an incentive stock option under Section 422 of the Code). All stock
appreciation rights granted with respect to Company Common Stock held by
employees other than the Retained Employees, whether or not then exercisable,
shall be assumed by Spinco and shall be exercisable upon the same terms and
conditions as under the applicable stock appreciation rights and the Company
stock option or stock incentive plan, except that each such stock appreciation
right shall be exercisable with respect to a whole number of shares of Spinco
Common Stock and with respect to an adjusted base value such that the
aggregate spread between the value of the Company Common Stock and the base
value of the stock appreciation right immediately before the Distribution
Date, and the per share ratio between the value of the Company Common Stock
and the base value of the stock appreciation right immediately before the
Distribution Date, shall be preserved.
 
  As soon as practicable after the signing of this Agreement, the Company
shall amend each stock option previously granted to a Retained Employee to
provide that for a period beginning not later than March 20, 1997 and ending 3
business days prior to the Distribution Date (the "Special Offer Period"),
each Retained Employee (i) shall be entitled to exercise his stock option or
options in full, without regard to the limitations on exercise to which the
option is otherwise subject, and (ii) that the Retained Employee shall have
the right, in the alternative, during the Special Offer Period, to surrender
such option or options, in whole or in part, and to receive from the Company
an amount equal to the excess of the aggregate Average Company Share Price (as
defined below) of the shares of stock subject to the surrendered options over
the aggregate exercise price thereof (such aggregate amount being referred to
as the "Special Offer Amount") (60% of such amount shall be retained by the
Company), payable in cash within ten days after the Effective Time (as defined
in the Merger Agreement) of the Merger (the "Special Offer"), provided that
the exercise or the surrender of options pursuant to the Special Offer shall
be contingent upon the consummation of the Merger pursuant to the Merger
Agreement, and provided further that the Special Offer shall expire at the end
of the Special Offer Period and any options held by Retained Employees and not
exercised or surrendered pursuant to the terms of the Special Offer (the
"Retained Options") shall thereafter continue in accordance with their terms
as in effect prior to the Special Offer, adjusted as
 
                                     B1-8
<PAGE>
 
described in the following paragraph. In addition to, but not in diminution,
of, the Company's obligation to provide the Special Offer, the Company may
take such further reasonable steps as are appropriate to encourage Retained
Employees to exercise their stock options prior to the Distribution Date. If
there are any Retained Options on the Distribution Date, whether or not then
exercisable, Spinco shall cause to be retained by the Company at the
Distribution Date an amount of cash equal to the spread between the aggregate
Average Company Share Price and the aggregate exercise price for such Retained
Options (the "Retained Option Amount"). For purposes of this Subsection (e),
the "Average Company Share Price" shall be equal to the average of the closing
prices of the Company Common Stock on the New York Stock Exchange Composite
Transactions Reporting System, as reported in the Wall Street Journal, for the
ten (10) trading days ending on the second trading day immediately prior to
the Effective Time (as defined in the Merger Agreement) of the Merger.
 
  Effective as of the Distribution Date, the Company shall continue to
maintain its stock option and stock incentive plans and shall cause each
Retained Option, whether or not then exercisable, granted to a Retained
Employee thereunder to be adjusted so that each such option shall be
exercisable for a whole number of shares of Company Common Stock and for a per
share exercise price such that the aggregate spread between the value of the
Company Common Stock and the exercise price immediately before the
Distribution Date, and the per share ratio between the value of the Company
Common Stock and the exercise price immediately before the Distribution Date,
shall be preserved, in accordance with Treasury Regulations (S)1.425-1 and in
such a manner as will not cause such assumption to be considered a
"modification" of the option under said section (or would not cause such
assumption to be a modification of the option if such option were an incentive
stock option under Section 422 of the Code). All stock appreciation rights
held by Retained Employees granted with respect to Company Common Stock shall
continue to be exercisable upon the same terms and conditions as prior to the
Distribution Date under the applicable stock option or stock incentive plan,
except that the Company shall cause each such stock appreciation right to be
adjusted so that it shall be exercisable with respect to a whole number of
shares of Company Common Stock and with respect to an adjusted base value such
that the aggregate spread between the value of the Company Common Stock and
the base value of the stock appreciation right immediately before the
Distribution Date, and the per share ratio between the value of the Company
Common Stock and the base value of the stock appreciation right immediately
before the Distribution Date, shall be preserved. In addition, the Retained
Options as adjusted pursuant to the terms of this paragraph, shall upon the
consummation of the Merger be further adjusted (by the compensation committee
of the Company following the Merger) in accordance with the terms of the
Company's stock option and stock incentive plans which provide for adjustments
in the event of a merger involving the Company.
 
  (f) Bonuses. Effective as of the Distribution Date, Spinco shall assume all
liability for bonuses payable to employees other than the Retained Employees
for 1997 pursuant to the Company's bonus plan, and the amount of such bonuses
shall be calculated without regard to the occurrence of the Distribution.
 
  (g) Workers' Compensation. Effective as of the Distribution Date, Spinco
shall assume all liability, including liability that arose prior to the
Distribution Date, for workers' compensation claims by employees other than
the Retained Employees, without regard to the date on which such claims become
payable. The Company shall continue to be responsible for all liability,
including liability that arose prior to the Distribution Date, for workers'
compensation claims by Retained Employees (or former employees of the Retained
Business), without regard to the date on which such claims become payable.
 
  (h) Preservation of Employee Plans. Except as provided in Section 4.1, no
provision of this Agreement shall be construed as a limitation on the right of
the Company or Spinco to amend or terminate any employee plan which the
Company or Spinco would otherwise have under the terms of such employee plan
or otherwise.
 
  1.6. Tax Liabilities; Indemnification. Notwithstanding any provision herein
to the contrary, any and all liabilities relating to taxes shall be allocated
solely in accordance with the provisions of the Tax Allocation Agreement (as
defined in the Merger Agreement). Nothing contained in this Section 1 or
elsewhere in this Agreement shall prejudice the rights of any party under the
Indemnification Agreement (as defined in the Merger Agreement) or the Tax
Allocation Agreement.

  1.7. Distribution of Subsidiary Stock; Merger of Subsidiaries; Spinco
Charter and Related Matters.
 
  (a) Immediately prior to the Distribution Date, the Company shall cause its
wholly-owned subsidiary, API (UK), to effect a dividend of the shares of
Ametek Filters Limited then held by API (UK) to the Company.

direct, wholly owned subsidiary, Amespace Inc., which owns 100% of the

  (c) Prior to the Distribution Date, the Company and Spinco shall cause (i)
the certificate of incorporation and by-laws of Spinco to be amended and
restated, in such form and with such provisions as the board of directors of
Spinco shall specify and (ii) Spinco to adopt and enter into a shareholders
rights agreement in the form and with the provisions specified by the board of
directors of Spinco.
 
  1.8. Issuance of Spinco Common Stock to the Company. Spinco shall issue to
the Company, contemporaneously with the contribution by the Company to Spinco
of the Contributed Assets and the assumption by Spinco of the Assumed
Liabilities, as contemplated in Sections 1.1 and 1.3, respectively, such
additional number of shares of Spinco Common Stock as may be required in order
for the Company to fulfill its obligations pursuant to Section 3.2.
 
  1.9. Certain Transaction Costs.
 
  (a) The parties shall share equally all of the following costs: (i) printing
and mailing costs with respect to the Registration Statements (as defined in
the Merger Agreement), (ii) costs of obtaining the audited financial
statements required for the Registrations Statements, (iii) filing fees with
respect to the Registration Statements and (iv) the filing fee required under
the HSR Act (as defined in the Merger Agreement) in connection with the
Merger.
 
  (b) The parties shall share equally all taxes and other governmental
assessments, charges or levies, costs of title insurance and other conveyance
costs which arise or are incurred (i) in connection with the transfer of the
Contributed Assets to Spinco pursuant to the Distribution and (ii) in
connection with or as a result of the Merger, in each case including but not
limited to all sales, value-added, registration, transfer (including
documentary and stamp) or similar taxes, whether domestic or foreign, but
excluding any taxes based upon the Company's net income.
 
  (c) Notwithstanding anything herein to the contrary, the maximum amount for
which the Company shall be liable under Sections 1.9(a) and 1.9(b) shall not
exceed $1,500,000 in the aggregate.

the date hereof and prior to the commencement of business on the Distribution
Date, the Company and Spinco shall take all such action as may be necessary or
appropriate to effect the Distribution, including without limitation the
specific actions set forth in Section 3.2 or Section 3.3 as applicable.
 
  3.2. The Distribution.
 
  (a) The Company and Spinco shall prepare and Spinco shall file with the
Securities and Exchange Commission (the "SEC"), a registration statement on
Form 10 (the "Form 10") to effect the registration of the Spinco Common Stock
pursuant to the Securities Exchange Act of 1934, as amended and the rules and
regulations promulgated thereunder (the "Exchange Act"). The Company and
Spinco shall use reasonable
 
                                     B1-11
<PAGE>
 
efforts to cause the Form 10 to be declared effective under the Exchange Act
or, if the Company reasonably determines that the Distribution may not be
effected without registering the Spinco Common Stock pursuant to the
Securities Act of 1933, as amended, and the rules and regulations promulgated
thereunder (the "Securities Act"), the Company shall use its best efforts to
cause the Spinco Common Stock to be registered pursuant to the Securities Act,
and thereafter effect the Distribution in accordance with the terms of this
Agreement, including without limitation, using its best efforts to cause such
registration statement to be declared effective.
 
  (b) The Company and Spinco shall cooperate in preparing, filing with the SEC
and causing to become effective any registration statements or amendments
thereto which are appropriate to reflect the establishment of, or amendments
to, any employee benefit and other plans contemplated in this Agreement to be

appropriate under any applicable state securities or blue sky laws or other
applicable laws in connection with the transactions contemplated in this

make effective, an application to permit listing or quotation of the Spinco
Common Stock on New York Stock Exchange and the Pacific Stock Exchange.
 
  (e) The Company's Board of Directors (or any duly appointed committee
thereof) shall in its sole discretion establish the record date for the
Distribution (the "Distribution Record Date") and the Distribution Date and
any appropriate procedures in connection with the Distribution (subject in
each case to the provisions of applicable law); such action shall not create
any obligation on the part of the Company to effect the Distribution. In no
event, however, shall the Distribution occur prior to such time as (i) the
Form 10 or other registration statement referred to in Section 3.2(a) shall
have been declared effective by the SEC, (ii) the Spinco Common Stock shall
have been approved for listing or quotation in accordance with Section 3.2(d)
and (iii) the conditions set forth in Section 5 have been satisfied or waived.
 
  (f) Subject to Section 5, following the Distribution Record Date, but prior
to the Distribution Date, the Company shall deliver to the Distribution Agent

Spinco Common Stock to be distributed in the Distribution and shall instruct
the Distribution Agent to distribute on the Distribution Date one share of
Spinco Common Stock for each share of Company Common Stock held by holders of
record of such stock on the Distribution Record Date. Spinco agrees to provide
all share certificates that the Distribution Agent shall require in order to
effect the Distribution. All shares of Spinco Common Stock issued in the
Distribution shall be duly authorized, validly issued, fully paid, non-
assessable and free of preemptive rights.
 
  (g) Immediately upon consummation of the Distribution the Company shall not
hold or beneficially own directly or indirectly any shares of Spinco Common

Spinco ratify any actions that are reasonably necessary or desirable to be
taken by Spinco to effectuate, prior to the Distribution Date, the
transactions contemplated in this Agreement in a manner consistent with the
terms of this Agreement, including, without limitation, the following : (a)

of Spinco to be in effect at the Distribution Date; (b) the election or
appointment of directors and officers of Spinco to serve in such capacities
commencing on the Distribution Date; (c) the adoption, preparation and
implementation of appropriate employee benefit plans on the Distribution Date;

directors (including, without limitation, plans, agreements or arrangements
pursuant to which securities of Spinco would be acquired by employees); and
(e) the registration under applicable securities laws of any securities of
Spinco issued or distributed pursuant to Section 3.2 and any securities

  3.4. Elimination of Intercompany Accounts. The net amounts of all
intercompany receivables, payables and indebtedness between the Company and
Retained Subsidiaries, on the one hand, and Spinco and the Spinco
Subsidiaries, on the other hand, as of the Distribution Date, will be
satisfied in full by capital contribution without any further documentation,
as of the Distribution Date.
 
  3.5. Resignations. The Company shall cause all employees, other than the
Retained Employees, to resign, effective as of the Distribution Date, from all
positions as officers or directors of the Company or as officers or directors
of any Company subsidiary in which they serve; provided, however, that such
employees shall be offered the same position as officer or director of Spinco
as of the Distribution Date.
 
  3.6. Guarantees. The Company and Spinco shall each use its best efforts to
have, on or prior to the Distribution Date, or as soon as practicable
thereafter, the Company or any Company subsidiary removed as guarantor of or
obligor for any indebtedness or obligations for which Spinco or any Spinco
Subsidiary is primarily liable. Spinco shall indemnify, defend and hold
harmless the Company from and against any and all liabilities of the Company
arising from a guarantee or other obligation of the Company for which Spinco
is primarily liable.
 
  3.7.  Litigation.
 
  (a) With respect to any action, suit, arbitration, inquiry, proceeding or
investigation by or before any court, any governmental or other regulatory or
administrative agency or commission or any arbitration tribunal (collectively,
any "Action") now pending or which may hereafter be commenced or threatened
relating to or arising from the Spinco Businesses which may result in
liability for the Company, the Company and Spinco shall each use its best
efforts to have Spinco or a Spinco subsidiary substituted as parties to such
Action in the place of and for the Company, any Retained Subsidiary or any
Retained Employee and to have the Company, any Retained Subsidiary or any
Retained Employee removed as parties to such Action following the Distribution
Date.
 
  (b) With respect to all Actions now pending or which may hereafter be
commenced or threatened relating to or arising from the Retained Business
which may result in liability for Spinco, the Company and Spinco shall each
use its best efforts to have the Company substituted as a party to such Action
in the place of and for Spinco, any Spinco subsidiary or any employee of
Spinco and to have Spinco, any Spinco subsidiary or any employee of Spinco
removed as parties to such Action following the Distribution Date.
 
  (c) At all times from and after the Distribution Date, each of the Company
and Spinco shall use reasonable efforts to make available to the other upon
written request its and its subsidiaries' officers, directors, employees and
agents as witnesses to the extent that such persons may reasonably be required
in connection with any Actions in which the requesting party may from time to
time be involved (without reimbursement for such persons' salaries).
 
  (d) At all times from and after the Distribution Date, each of the Company
and Spinco shall use reasonable efforts to make available to the other upon
written request its and its subsidiaries records, books, contracts,
instruments, computer data and other data which may reasonably be required in
connection with any Actions in which the requesting party may from time to
time be involved.
 
                                 4. COVENANTS.
 
  4.1. Employee Plans
 
  (a) The Company shall continue to employ the Retained Union Employees
immediately after the Distribution Date under the terms and conditions of the
Collective Bargaining Agreements.
 
  (b) The Company shall continue to employ the Retained Employees other than
the Retained Union Employees immediately after the Distribution Date on the
same terms and conditions as they are employed immediately prior to the
Distribution Date. For the two year period following the Distribution Date,
the Company agrees that the compensation and benefit levels for any such
Retained Employees who continue to be employed
 
                                     B1-13
<PAGE>
 
by the Company will be generally comparable in the aggregate as those in
effect for such Retained Employees immediately prior to the Distribution Date.
 
  (c) The Company shall give the Retained Employees (including Retained Union
Employees) credit for their service with the Company prior to the Distribution
Date for all purposes, including eligibility, vesting and benefit accrual
under any vacation policy or any employee benefit plan covering the Retained
Employee (whether in existence as of the Distribution Date or adopted
thereafter); provided, however, that the Company shall not be required to
provide such past service credit for purposes of benefit accrual under any
pension or retirement plan other than with respect to Retained Union
Employees. Except as otherwise provided in this Section 4.1, the Company or
any successor shall have the right to amend and terminate any of its employee
benefit plans, programs or arrangements at any time in accordance with
applicable law. In the event the Company or any successor thereto shall
terminate the services of any Retained Employee within a two year period
following the Distribution Date, the Company or any successor thereto shall
pay severance pay to such Retained Employee in an amount no less than the
amount that such employee would have received if the severance policy of the
Company in effect immediately prior to the Distribution Date had been in
effect on the date of such Employee's termination. In addition, following the
consummation of the Merger, medical, disability and life insurance benefits
for the Retained Employees (including the Retained Union Employees) shall be
available without any exclusions or limitations for pre-existing conditions or
treatments or waiting periods for eligibility (other than any pre-existing
condition that was not waived by the Company's corresponding plan prior to the

<PAGE>
 
  8.2. Insurance. On or before the Distribution Date, the Company shall
transfer and assign to Spinco all of the Company's insurance policies other
than any policy which relates solely to the Retained Business. If any policy
by its terms may not be assigned, it is the intent of the parties that Spinco
receive the benefit of any coverage under any insurance policy. The Company
agrees to keep such policy in effect during the remaining term of the policy

affect Spinco's entitlement to the benefits of, or coverage under, such
policy.

subsidiaries, or by the Company and its subsidiaries for the benefit of Spinco
and its subsidiaries, during the relevant month to be remitted to the party

receipt thereof.
 
                 9. NON-COMPETITION AND ACCESS TO INFORMATION.
 
  9.1. Covenant Not to Compete.
 
  (a) Spinco agrees for a period of five (5) years after the Distribution
Date, directly or indirectly, in the Territory (as defined below) (i) not to
sell any products or render services or to have any interest as a shareholder,
owner, agent, consultant, or otherwise in any other person, firm or
corporation engaged in the manufacture or sale of the kind of products, or the
rendering of the kind of services, which are currently being manufactured,
sold or provided by the Retained Business or (ii) solicit any customer or
supplier of the Retained Business as of the date hereof for any purpose
competitive with the business of the Retained Business.
 
  (b) Spinco agrees that, for a period of two years after the Distribution
Date, neither it nor any corporation or other entity directly or indirectly
controlled by, or successor to it, shall, without the Company's prior
approval, hire, retain, employ or engage in any business with any Retained
Employee, nor will it, directly or indirectly offer to transfer or retain any
of the Retained Employees. The Company agrees that, for a period of two years
after the Distribution Date, neither it nor any corporation or other entity
directly or indirectly controlled by, or successor to it, shall, without
Spinco's prior approval, hire, retain, employ or engage in any business with
any Spinco Employee, nor will it, directly or indirectly offer to transfer or
retain any of the Spinco Employees. The parties' obligations under this
Section 9.1(b) shall not apply to any Retained Employee or Spinco Employee
after such individual's employment with the Company or Spinco, respectively,
has terminated; provided that such termination is not attributable to conduct
by the other party which constitutes a breach of this Section 9.1(b).
 
  (c) Nothing contained in this Section 9 shall prohibit Spinco from acquiring
any business a minority component (as defined below) of which is engaged in a
business in competition with the Retained Business. Nothing in this Section 9
shall prohibit Spinco from continuing the filtration applications for products
from the Company's high temperature textile business and specialty metals
business, including any developments and extensions thereof. For purposes
hereof, "minority component" shall mean a business in competition with the
Retained Business which either (i) represents less than 25 percent of the
consolidated assets and consolidated revenues of the parent entity being
acquired by Spinco that owns or controls such minority component or (ii) had
total revenues during for its most recently completed fiscal year of
$10,000,000 or less. If any such minority component represents more than 10
percent of either the consolidated assets or consolidated revenues of the
parent entity owning or controlling such minority component, then no later
than 30 days following Spinco's acquisition of such parent entity, Spinco
shall offer to sell to the Company such minority component at a purchase price
(which shall be exclusively in cash unless Spinco otherwise agrees) equal to
its Fair Market Value (as defined below). Following such an offer, the parties
shall endeavor to agree on the fair market value of such component ("Fair
Market Value"). If the parties are unable to agree on a Fair Market Value
within 15 days after such offer is made, then each of Spinco and the Company
shall retain an independent investment bank or accounting firm who shall be
instructed to appraise such minority component and, based on such appraisal,
to
 
                                     B1-16
<PAGE>
 
determine the Fair Market Value thereof. In such case, the Fair Market Value
shall equal the average of the Fair Market Values determined by such
appraisers, provided that if an appraiser reports a range of values, the
midpoint of such range shall be deemed the Fair Market Value determined by
such appraiser for purposes of this provision. The Company shall have the
option of acquiring such minority component at such Fair Market Value during
the 30 day period (as extended to comply with waiting periods under applicable
law) following the determination thereof. In any documentation relating to
such acquisition, Spinco's representations and warranties with respect to such
minority component shall be limited only to the period of time during which
such minority component was owned by Spinco (subject, however, to the
following sentence). To the extent assignable, Spinco will assign to the
Company Spinco's rights with respect to such minority component under the
documentation pursuant to which Spinco acquired the same. If the Company does
not acquire such minority component within such 30 day period (as so
extended), Spinco may thereafter retain such minority component free from any
restrictions under this Section 9.1
 
  (d) For purposes of this Section 9.1, ownership of five (5) percent or less
of any class of outstanding securities of a company whose securities are
listed on a national securities exchange or quoted or traded on the National
Association of Securities Dealers Automated Quotation System shall not be
deemed to constitute ownership or participation in the ownership of the
business of such company and shall not constitute a violation of Section
9.1(a) above.
 
  (e) If any portion of this Section 9.1 shall be determined to be invalid and
unenforceable, such determination shall not affect the validity or
enforceability of the balance hereof, and such balance shall remain in full
force and effect.
 
  (f) The parties agree that the "Territory" shall be worldwide.
 
  9.2. Access to Information.
 
  (a) Provision of Corporate Records. Each of the Company and Spinco shall use
its best efforts to arrange, as soon as practicable following the Distribution
Date, for the delivery to the other party of the relevant portions of all
corporate books and records. The Company shall maintain in its possession all
relevant portions of the corporate books and records relating directly and
primarily to the Retained Business, Retained Employees, Retained Assets or
Retained Liabilities, including all active agreements, files and government
filings and licenses.
 
  From and after the Distribution Date, all such books, records and copies
shall be the property of the Company. Spinco shall retain in its possession
all relevant portions of all corporate books and records relating to the
Spinco Businesses, Spinco Employees, Contributed Assets and Assumed
Liabilities and all general corporate books and records including all active
agreements, files and government filings and licenses. From and after the
Distribution Date, all such books, records and copies referred to in the
preceding sentence shall be the property of Spinco. Any material containing
incidental information relating to the Retained Business, but relating
primarily to the Spinco Businesses, shall be retained by Spinco and copies of
the relevant portions thereof shall be provided to the Company.
 
  (b) Access to Information. From and after the Distribution Date, each of the
Company and Spinco shall afford to the other and its authorized accountants,
counsel and other designated representatives reasonable access during normal
business hours, subject to appropriate restrictions for classified
information, to the personnel, properties, books and records of such party and
its subsidiaries insofar as such access is reasonably required by the other
party.
 
  (c) Confidentiality. The Company shall hold, and shall cause its respective
employees, agents, consultants and advisors to hold, in strict confidence,
using the same efforts it uses protecting its own confidential and proprietary
information, all confidential or proprietary information concerning the Spinco
Businesses in its possession (except to the extent that such information has
been (i) in the public domain or becomes publicly known through no wrongful
act of any of the Company or its employees, agents, consultants or advisors,
(ii) received from a party who is under no confidentiality or secrecy
obligation with respect thereto, or (iii) disclosed
 
                                     B1-17
<PAGE>
 
pursuant to governmental or judicial requirements). Spinco shall hold, and
shall cause its respective employees, agents, consultants and advisors to
hold, in strict confidence, using the same efforts it uses protecting its own
confidential and proprietary information, all information confidential or
proprietary information concerning the Retained Business in its possession
(except to the extent that such information has been (i) in the public domain
or becomes publicly known through no wrongful act of any of Spinco or its
employees, agents, consultants or advisors, (ii) received from a party who is
under no confidentiality or secrecy obligation with respect thereto, or (iii)
disclosed pursuant to governmental or judicial requirements).
 
  (d) Cooperation with Respect to Government Filings and Reports. Each of the
Company and Spinco agree to provide the other party with such cooperation and
information, including, but not limited to, all records, books, contracts,
instruments, computer data and other data, as may be reasonably requested by
the other in connection with the preparation or filing of any government
report or other government filing, contemplated by this Agreement or in
conducting any other government proceeding relating to pre-Distribution
events. Such cooperation and information shall include, without limitation,
promptly forwarding copies of appropriate notices and forms or other
communications received from or sent to any government authority to the
appropriate party. Each party shall make its employees and facilities
available during normal business hours and on reasonable prior notice to
provide explanation of any documents or information provided hereunder.
 
                              10. MISCELLANEOUS.
 
  10.1. Termination. This Agreement (a) may be terminated at any time prior to
the Distribution Date by mutual written consent of the Company and Culligan,

exhibits hereto, and together with the Merger Agreement and the other
Ancillary Agreements (as defined in the Merger Agreement), to the extent

parties hereto with respect to its subject matter, except any confidentiality
agreements executed by the Company and Culligan.
 
  10.3. No Third Party Rights. No person or entity other than the parties
hereto, including, but not limited to, any former or present employee of
Spinco or the Company (including any assignee or beneficiary thereof) shall
have any rights with respect to any obligations of any entity under this

amendment shall be in writing signed on behalf of the party or parties to be
charged. At any time prior to the Distribution Date, either the Company or
Spinco may waive compliance by the other party with any of the agreements or
conditions contained in this Agreement with the prior consent of Culligan. Any
agreement on the part of a party to any such waiver shall be valid only if set
forth in an instrument in writing signed on behalf of such parties. The
failure of any party to this Agreement to assert any of its rights under or to
enforce any provision of this Agreement or otherwise shall not constitute a
waiver of its rights under such provision or any other provision.

  whether or not resulting from Third Party Claims (as defined in Section
  2.3(a) hereof), including interest and penalties recovered by a third party
  with respect thereto and out-of-pocket expenses and reasonable attorneys'

  any law, rule or regulation of any Governmental Entity by the Company or
  Spinco or any of their Subsidiaries or any director, officer, employee or
  agent of the Company or Spinco or any of their Subsidiaries (collectively,
  "Legal Matters") occurring or alleged to have occurred at or prior to the
  Effective Time in respect of the Spinco Businesses;
 
    (vi) relating to or arising from any claim that the execution, delivery
  or performance by the Company or Spinco of the Merger Agreement and each
  Ancillary Agreement to which it is or will be a party or the consummation
  of the transactions contemplated thereby results in a violation or breach
  of, or constitutes a default or impermissible transfer under, or gives rise
  to any right of termination, first refusal or consent under or gives rise
  to any right of amendment, cancellation or acceleration of any material
  benefit under, any Contract to which the Company or any of its Subsidiaries

    (ii) arising out of or resulting from any untrue statement or alleged
  untrue statement of a material fact contained in any of the Registration
  Statements or in the Proxy Statement, or any omission or alleged omission

    (iv) relating to or arising from any claim that the execution, delivery
  or performance by Parent or Merger Sub of the Merger Agreement and each

  to any right of termination, first refusal or consent under or gives rise
  to any right of amendment, cancellation or acceleration of any material
  benefit under, any Contract to which Parent or Merger Sub is a party prior
  to the Distribution.
 
  2.3. Procedures Relating to Indemnification. (a) In order for an Indemnitee
to be entitled to any indemnification provided for under this Agreement in
respect of, arising out of or involving a claim made by any Person who is not
an Indemnitee against the Indemnitee (a "Third Party Claim"), such Indemnitee
must notify the party who may become obligated to provide Indemnification
hereunder (the "indemnifying party") in writing, and in reasonable detail, of
the Third Party Claim promptly; provided, however, that failure to give such
notification shall not affect the indemnification provided hereunder except to
the extent the indemnifying party shall have been prejudiced as a result of
such failure. After any required notification (if applicable), the Indemnitee
shall deliver to the indemnifying party, promptly after the Indemnitee's
receipt thereof, copies of all notices and documents (including court papers)
received by the Indemnitee relating to the Third Party Claim.
 
  (b) If a Third Party Claim is made against an Indemnitee, the indemnifying
party will be entitled to participate in the defense thereof and, if it so
chooses, to assume the defense thereof (at the expense of the
 
                                     B2-3
<PAGE>
 
indemnifying party) with counsel selected by the indemnifying party and
reasonably satisfactory to the Indemnitee. Should the indemnifying party so
elect to assume the defense of a Third Party Claim, the indemnifying party
will not be liable to the Indemnitee for any legal expenses subsequently
incurred by the Indemnitee in connection with the defense thereof; provided
that if, under applicable standards of professional conduct (as advised by
counsel to the indemnifying party), a conflict on any significant issue
between the Indemnitee and the indemnifying party or between any two or more
Indemnitees exists in respect of such Third Party Claim, the indemnifying
party shall pay the reasonable fees and expenses of one such additional
counsel as may be required to be retained in order to resolve such conflict.
If the indemnifying party assumes such defense, the Indemnitee shall have the
right to participate in the defense thereof and to employ counsel, at its own
expense, separate from the counsel employed by the indemnifying party, it
being understood that the indemnifying party shall control such defense. The
indemnifying party shall be liable for the fees and expenses of counsel
employed by the Indemnitee for any period during which the indemnifying party
has not assumed the defense thereof (other than during any period in which the
Indemnitee shall have failed to give notice of the Third Party Claim as
provided above). If the indemnifying party chooses to defend or prosecute a
Third Party Claim, all the parties hereto shall cooperate in the defense or
prosecution thereof, which cooperation shall include the retention and the
provision to the indemnifying party of records and information which are
reasonably relevant to such Third Party Claim, and making employees available
on a mutually convenient basis to provide additional information and
explanation of any material provided hereunder. If the indemnifying party
chooses to defend or prosecute any Third Party Claim, the Indemnitee will
agree to any settlement, compromise or discharge of such Third Party Claim
which the indemnifying party may recommend and which by its terms obligates
the indemnifying party to pay the full amount of liability in connection with
such Third Party Claim; provided, however, that, without the Indemnitee's
consent, the indemnifying party shall not consent to entry of any judgment or
enter into any settlement (x) that provides for injunctive or other
nonmonetary relief affecting the Indemnitee, (y) that does not include as an
unconditional term thereof the giving by each claimant or plaintiff to such
Indemnitee of a release from all liability with respect to such claim, or (z)
in the case of any Legal Matter. Whether or not the indemnifying party shall
have assumed the defense of a Third Party Claim, the Indemnitee shall not
admit any liability with respect to, or settle, compromise or discharge, such
Third Party Claim without the indemnifying party's prior written consent.
 
  (c) In order for an Indemnitee to be entitled to any indemnification
provided for under this Agreement in respect of a claim that does not involve
a Third Party Claim, the Indemnitee shall deliver notice of such claim with
reasonable promptness to the indemnifying party. The failure by any Indemnitee
to so notify the indemnifying party shall not relieve the indemnifying party
from any liability which it may have to such Indemnitee under this Agreement,
except to the extent that the indemnifying party shall have been actually
prejudiced by such failure. Any notice pursuant to this Section 2.3(c) shall
contain a statement, in prominent and conspicuous type, that if the
indemnifying party does not dispute its liability to the Indemnitee with
respect to the claim made in such notice (the "Claim") by notice to the
Indemnitee prior to the expiration of a 30-calendar-day period following the
indemnifying party's receipt of the second notice of the Claim, the Claim
shall be conclusively deemed a liability of the indemnifying party. If the
Indemnitee has provided the indemnifying party two such notices not less than
30 days apart and the indemnifying party does not notify the Indemnitee prior
to the expiration of a 30-calendar-day period following its receipt of the
second such notice that the indemnifying party disputes its liability to the
Indemnitee under this Agreement, the Claim shall be conclusively deemed a
liability of the indemnifying party under this Agreement and the indemnifying
party shall pay the amount of such liability to the Indemnitee on demand or,
in the case of any notice in which the amount of the Claim (or any portion
thereof) is estimated, on such later date when the amount of the Claim (or any
portion thereof) becomes finally determined. If the indemnifying party has
timely disputed its liability with respect to the Claim, as provided above,
the indemnifying party and the Indemnitee shall proceed in good faith to
negotiate a resolution of the Claim and, if the Claim is not resolved through
negotiations, such Indemnitee shall be free to pursue such remedies as may be
available to it under applicable law.
 
  2.4. Certain Limitations. The amount of any Indemnifiable Losses or other
liability for which indemnification is provided under this Agreement shall be
net of any amounts actually recovered by the
 
                                     B2-4
<PAGE>
 
Indemnitee from third parties (including, without limitation, amounts actually
recovered under insurance policies other than pursuant to retrospective or
other self-insurance type policies) with respect to such Indemnifiable Losses
or other liability. The amount of any Indemnifiable Losses or other liability
for which indemnification is provided under this agreement shall be increased
by the income taxes (if any) payable by an Indemnitee with respect to the
inclusion of such amount in such Indemnitee's taxable income and reduced by
any tax benefit actually realized by such Indemnitee with respect to such
Indemnifiable Loss; provided, however, that in computing the amount of any
such tax benefit, the Indemnitee shall be deemed to recognize all other items
of loss, deduction or credit before claiming such Indemnifiable Loss on the
Indemnitee's relevant tax returns. To the extent permitted by law, Spinco,
Parent, the Company and their respective Affiliates will use their best
efforts to claim such Indemnifiable Loss on their respective tax returns and
utilize such tax benefit in a manner which is designed to maximize (on a
present value basis) the tax benefit described herein. Any indemnifying party
hereunder shall be subrogated to the rights of the Indemnitee upon payment in
full of the amount of the relevant Indemnifiable Loss. An insurer who would
otherwise be obligated to pay any claim shall not be relieved of the
responsibility with respect thereto or, solely by virtue of the
indemnification provisions hereof, have any subrogation rights with respect
thereto. If any Indemnitee recovers an amount from a third party in respect of
an Indemnifiable Loss for which indemnification is provided in this Agreement
after the full amount of such Indemnifiable Loss has been paid by an
indemnifying party or after an indemnifying party has made a partial payment
of such Indemnifiable Loss and the amount received from the third party
exceeds the remaining unpaid balance of such Indemnifiable Loss, then the
Indemnitee shall promptly remit to the indemnifying party the excess (if any)
of (A) the sum of the amount theretofore paid by the indemnifying party in
respect of such Indemnifiable Loss plus the amount received from the third
party in respect thereof, less (B) the full amount of such Indemnifiable Loss
or other liability.
 
  2.5. Limitation on Indemnification. (a) With respect to Indemnifiable Losses
arising under Section 2.1(iv), Spinco shall not have any liability under
Article II of this Agreement unless the aggregate of all Indemnifiable Losses
for which Spinco would, but for this Section 2.5, be liable under Article II
exceeds on a cumulative pre-tax basis an amount equal to $800,000 (the "Basket
Amount"); provided, that, once the Basket Amount is exceeded, Spinco shall
only pay Indemnifiable Losses that are in excess of such Basket Amount.
Notwithstanding the foregoing, Spinco's liability for Indemnifiable Losses
arising under Section 2.1(iv) shall be limited (i) in the aggregate to
$25,000,000 and (ii) to only those Indemnifiable Losses for which Spinco has
received written notice of on or prior to eighteen months from the Closing
Date.
 
  (b) Notwithstanding any other provision hereof, in no event shall any party
be liable for or obligated to indemnify any other party from and against any
punitive damages (other than punitive damages asserted in a Third Party Claim)
or damages which could have been reasonably avoided as a result of customary
and prudent business practices.
 
  2.6. Exclusive Remedy. The parties hereto agree that the indemnification
provided in this Agreement and in the Tax Allocation Agreement shall be the
exclusive remedies of the parties with respect to the matters covered hereby
and thereby. Notwithstanding anything herein to the contrary, no party shall
be entitled to any indemnification hereunder with respect to the matters
covered by the indemnification provisions of the Tax Allocation Agreement,
which shall be the exclusive provisions with respect to such matters. In no
event shall any of such indemnification provisions herein and/or in the Tax
Allocation Agreement entitle any party to more than one recovery with respect
to any Indemnifiable Loss.

                         TRANSITION SERVICES AGREEMENT
 
  AGREEMENT dated as of February 5, 1997, by and between Ametek, Inc., a
Delaware corporation ("Spinco"), and Culligan Water Company, Inc., a Delaware
corporation (the "Company").
 
                             W I T N E S S E T H :
 
  WHEREAS, Spinco and the Company have entered into a Contribution and
Distribution Agreement (the "Distribution Agreement") dated as of February 5,
1997, pursuant to which, among other things, all of the businesses of the
Company other than the Retained Business (as defined therein) shall be
contributed to Spinco (the "Contribution") prior to the distribution to the
stockholders of the Company of all of the capital stock of Spinco (the
"Distribution"), in accordance therewith (terms defined in the Distribution
Agreement shall have the same meaning when used herein);
 
  WHEREAS, following such Contribution and Distribution, Culligan Water
Company, Inc., a Delaware corporation ("Merger Sub") and a wholly owned
subsidiary of Culligan Water Technologies, Inc., a Delaware corporation
("Culligan"), shall be merged with and into the Company (the "Merger"),
pursuant to an Agreement and Plan of Merger and Reorganization dated as of
February 5, 1997 (the "Merger Agreement") by and among Culligan, Merger Sub,
the Company and Spinco; and
 
  WHEREAS, as a condition to the consummation of the Merger, Spinco shall
provide the Company with certain transition services and support for a limited
period of time after the date hereof, subject to terms and conditions set
forth herein;
 
  NOW, THEREFORE, the parties agree as follows:
 
  1. Transition Services. For a period of up to 9 months after the date hereof
(subject to extension as provided below), Spinco shall provide the Company
with the services set forth on Schedule A hereto (collectively, the
"Services"). The Company may, from time to time during the term hereof,
request one or more of such Services by written notice and the same shall be
provided as promptly as reasonably practicable following such request. Spinco
agrees to provide such Services in a manner consistent with the manner in
which such services were provided by the Company to the Retained Business
prior to the Distribution. In consideration for such Services, the Company
shall pay to Spinco a fee based on Spinco's fully burdened costs of providing
such Services, which shall be mutually agreed by Spinco and the Company prior
to the time such Services are so provided.
 
  2. Billing. Within five days of the end of each month, Spinco shall deliver
to the Company an invoice setting forth the amounts due, if any, for each of
the Services provided during such month. Terms of payment on any invoice sent
pursuant hereto will be thirty days from the date of such invoice, and all
invoices will be paid without deduction or setoff for any reason whatsoever,
except upon the prior written consent of Spinco.
 
  3. Term. The Agreement shall become effective as of the date hereof and
terminate on 9 months hereafter, unless extended by the mutual consent of the
parties for an additional 3-month period on the same terms and conditions
provided for herein (which consent shall not be unreasonably withheld).
 
  4. Termination. The Company may, at its option, terminate this Agreement at
any time on 30 days prior written notice to Spinco.
 
  5. Force Majeure. Neither party shall be responsible for any delay in
performance, or nonperformance, caused by circumstances beyond the reasonable
control of the party affected, including, but not limited to, acts of God,
fire, flood, war, government action, whether federal, state or local,
including any law, regulation, order or notice of any governmental agency or
authority, accident, labor dispute or shortage, explosion, transportation or
utilities or failure of machinery, piping or equipment.
 
                                     B3-1
<PAGE>
 
  6. No Warranty. Spinco makes no warranty concerning the adequacy or
effectiveness of any of the Services and all such Services are provided "AS
IS", without warranty or liability, except for Spinco's bad faith or willful
misconduct. In no event, however, will Spinco be liable for any special,
consequential or punitive damages.
 
  7. Notices. All notices, requests, demands and other communications provided
for by this Agreement shall be in writing and shall be deemed given on the

                              TRADEMARK AGREEMENT
 
  This TRADEMARK AGREEMENT dated as of the    day of      , 1997 between
AMETEK, Inc., a Delaware corporation (the "Company") and Ametek Aerospace
Products, Inc., a Delaware corporation ("New Ametek").
 
  WHEREAS, on the date hereof, the Company is distributing to the Company's
stockholders all of the shares of common stock of New Ametek and, prior to
such distribution, is contributing to New Ametek all of its assets and
business other than the Retained Assets as defined in and pursuant to the
Contribution and Distribution Agreement, dated as of February 5, 1997, between
the Company and New Ametek (the "Distribution Agreement"); and
 
  WHEREAS, following the Distribution (as defined in the Distribution
Agreement), Culligan Water Company, Inc. ("Merger Sub"), a wholly owned
subsidiary of Culligan Water Technologies, Inc. ("Culligan"), will merge into
the Company, pursuant to the terms and conditions of an Agreement and Plan of
Merger and Reorganization, dated as of February 5, 1997, as amended and
restated, among Culligan, Merger Sub, the Company and New Ametek (as
thereafter amended, the "Merger Agreement"), with the Company being the
surviving corporation and changing its name to "Culligan Water Company, Inc.";
and
 
  WHEREAS, it is a condition to the consummation of the transactions
contemplated by the Merger Agreement that the Company and New Ametek enter
into this Agreement which sets forth the Company's right to use the "Ametek"
trade name and certain related trademarks, service marks and logos (as more
fully described below) in connection with the Retained Business (as defined in
the Distribution Agreement), subject to the terms and conditions set forth
herein;
 
  NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency whereof is hereby acknowledged, the parties agree as follows:
 
  1. DEFINITIONS.
 
  (a) All capitalized terms not specifically defined herein shall have the
same meaning ascribed to them in the Distribution Agreement and Merger
Agreement.
 
  (b) The term "Mark(s)" shall be used herein to mean the "Ametek" trade name
and any of New Ametek's trademarks, service marks or logos which use the word
"Ametek" and are currently in use by the Retained Business, in substantially
the full and complete form identified in Exhibit B hereto.
 
  (c) The term "Products" shall mean the products currently being manufactured
and/or sold by the Retained Business identified in Exhibit C hereto, as the
same may be improved and modified from time to time by the Company and other
products that have substantially the same function and purpose as those
products currently manufactured and/or sold by the Retained Business.
 
  2. RIGHT TO USE. (a) The Company and New Ametek agree that during the
Initial Term (as defined below), and subject to the terms and conditions
hereof, the Company has retained, as part of the Retained Assets, the right to
use the Marks on the Products and in connection with the manufacturing,
advertising, promotion, distribution, sales and servicing thereof, but only in
the product and marketing channels in which such Marks are currently used by
the Retained Business or any expansion thereof, which is in the water
filtration field, and only in the manner permitted hereunder. Such right to
use the Marks shall be equivalent in scope to a worldwide, exclusive license
to use the Marks subject to the conditions set forth earlier in this
paragraph.
 
 
                                     B4-1
<PAGE>
 
  (b) With respect to each Renewal Term (as defined below), New Ametek hereby
grants to the Company for such Renewal Term and subject to the terms and
conditions hereof, a worldwide, exclusive license to use the Marks on the
Products and in connection with the manufacturing, advertising, promotion,
distribution, sales and servicing thereof, but only in the product and
marketing channels in which such Marks are currently used by the Retained
Business or any expansion thereof, which is in the water filtration field and
only in the manner permitted hereunder.
 
  (c) The Company warrants, represents and agrees that it shall not use the
Marks, alone or in combination with other terms, as part of a corporate name.
 
  (d) Concurrently with the execution hereof, Culligan is delivering to New
Ametek, a duly executed guaranty, substantially in the form of Exhibit A
hereto, guaranteeing the Company's obligations hereunder.
 
  3. TERM. This Agreement shall commence on the date hereof and, subject to
   earlier termination as provided below, shall continue for an initial term
   of five (5) years (the "Initial Term"); provided that the Company may
   extend the term hereof for up to three (3) successive periods of one (1)
   year (each, a "Renewal Term" and collectively the "Renewal Terms") by
   written notice given at least 90 days prior to the end of such Initial Term
   or any Renewal Term, as the case may be.
 
  4. ROYALTIES.
 
  (a) No royalty shall be applicable with respect to the Initial Term. The
Company agrees to pay to New Ametek, as a royalty, $1,000,000 for each Renewal
Term (the "Annual Royalty").
 
  (b) The Annual Royalty for any Renewal Term shall be paid to New Ametek in
two equal installments, with the first installment to be made no later than
the Semi-Annual Date (as defined below) occurring during such Renewal Term and
the second installment shall be made no later than the last day of such
Renewal Term; provided that, if this Agreement for any reason terminates
during a Renewal Term, the Annual Royalty for the pro-rata portion for such
year, to the extent unpaid, shall become immediately due and payable. A "Semi-
Annual Date" shall be the day occurring six months after the date hereof and
each subsequent anniversary of such day.
 
  5. AUDIT. The Company shall keep true, complete and accurate records and
books of account containing particulars customary to the trade with respect to
all Products bearing any of the Marks which are manufactured or sold by the
Company or its subsidiaries, parents or affiliates. Such records, books of
account and related information shall be kept in the Company's principal place
of business and said records, books and the supporting data shall be
available, upon reasonable advance notice and during normal business hours, at
the request of New Ametek for inspection by an independent certified public
accountant retained by New Ametek at New Ametek's expense for the purpose of
verifying any matter relevant to this Agreement.
 
  6. MARKING. The Company agrees to mark the Products (including samples
thereof distributed to the public) with the appropriate common law or
statutory trademark notice to maintain the validity and protectability of the
Marks. (For example, the trademark notice in the United States would consist
of Ametek7.) Such notices shall be placed on all Products (including samples
thereof distributed to the public) and all hang-tags and packaging for the
Products and in all other ways customary in the trade for articles distributed
to the public and in accordance with the legal requirements of any relevant
jurisdiction.
 
  7. Quality of Goods and Services. The design, manufacture, styling,
workmanship of all Products (including all services in connection therewith),
and all advertising, marketing and promotional materials relating to any of
the Products and every use of the Marks shall at all times be in conformance
with industry standards and be of good and marketable quality, provided that
the quality level of such Products shall at no time be at a level below that
maintained by New Ametek as of the date hereof and shall at all times fully
comply with all applicable laws and regulations of any relevant jurisdiction.
Any proposed material change in the use of any of
 
                                     B4-2
<PAGE>
 
the Marks or any new item of the Products, which differs from the line of
products being offered by the Retained Business immediately prior to the date
hereof and set forth in Exhibit B, shall require New Ametek's prior approval,
which shall not be unreasonably withheld or delayed. The Company shall furnish
to New Ametek, at New Ametek's request not more than once every six (6)
months, samples of the Company's products and other materials using the Marks.
In the event New Ametek provides written notice to the Company stating that
one of the Company's products does not meet the quality standards under this
Section 7, then New Ametek or its authorized agents and representatives shall
have the right, at New Ametek's expense, to inspect all facilities or premises
maintained by or on behalf of the Company including, without limitation, its
showrooms and the plants, factories or other manufacturing, production or
warehouse facilities of the Company at which the Products are being or are
proposed to be manufactured, produced, displayed or stored to ascertain
whether the quality standards provided for in this Section 7 are being
satisfied. Such inspection shall be conducted in a manner that shall not
unreasonably interfere with the business operations of the Company. In the
event the Company receives written notice from New Ametek setting forth a
reasonable basis and with specificity that the Products do not comply with New
Ametek's quality standards under this Section 7, the Company shall achieve
conformity with such standards within 30 days of receipt of such notice, or,
if conformity with such standards is not reasonably achievable within such 30
day period, then the Company shall have up to 60 days to achieve such
conformity provided that the Company commences such remedial steps within such
30-day period and diligently pursues such remedial steps.
 
  8. Ownership of Marks. The Company acknowledges that New Ametek is the sole
and exclusive owner of the Marks except as contemplated by Section 2, and the
Company shall not contest New Ametek's rights in the Marks or the validity of
this Agreement. The Company will cooperate with New Ametek and execute any and
all documents during the term of this Agreement, reasonably requested by New
Ametek and at New Ametek's expense, in order to protect and maintain New
Ametek's exclusive rights and title to the Marks including, without
limitation, filing any applications, recordings of this Agreement or other
documentation regarding the Marks with governmental authorities having
jurisdiction over the granting and maintaining of trademark registrations. The
Company further agrees to notify New Ametek of any infringing use of the Marks
by others promptly after such infringing use comes to the Company's attention.
New Ametek shall have the sole right to bring infringement or unfair
competition proceedings involving the Marks except as set forth in Paragraph
15(a).
 
  9. Maintenance of Marks. New Ametek agrees to take all necessary steps to
maintain the Marks in full force and effect during the term of this Agreement.
 
  10. Termination. New Ametek shall have the right to terminate this Agreement
upon 30-days' written notice to the Company if (a) any Insolvency Event (as
defined below) occurs with respect to the Company, or (b) the Company breaches
in any material respect any of its duties or obligations under this Agreement
and such breach is not remedied by the Company within 30 days of receipt of
written notice from New Ametek setting forth such breach, or if such breach is
not reasonably remediable within such 30 day period, then the Company shall
have up to 60 days to remedy such breach provided that the Company commences
such remedial steps within such 30-day period and diligently pursues such
remedial steps. An "Insolvency Event" shall have occurred if (A) an
involuntary proceeding shall be commenced or an involuntary petition shall be
filed in a court of competent jurisdiction seeking (i) relief in respect of
the Company, or of a substantial part of the property or assets of the
Company, under Title 11 of the United States Code, as now constituted or
hereafter amended, or any other Federal, state or foreign bankruptcy,
insolvency, receivership or similar law, (ii) the appointment of a receiver,
trustee, custodian, sequestrator, conservator, liquidator, administrator or
similar official for the Company or for a substantial part of the property or
assets of the Company or (iii) the winding-up or liquidation of the Company;
and such proceeding or petition shall continue undismissed for 60 days or an
order or decree approving or ordering any of the foregoing shall be entered;
or (B) the Company shall (i) voluntarily commence any proceeding or file any
petition seeking relief under Title 11 of the United States Code, as now
constituted or hereafter amended, or any other Federal, state or foreign
bankruptcy, insolvency, receivership or similar law, (ii) consent to the
institution of, or fail to contest in a timely and appropriate manner, any
proceedings or the filing
 
                                     B4-3
<PAGE>
 
of any petition described in (A) above, (iii) apply for or consent to the

proceeding, (v) make a general assignment for the benefit of creditors, (vi)
become unable, admit in writing its inability or fail generally to pay its
debts as they become due or (vii) take any action for the purpose of effecting
any of the foregoing. The Company may terminate this Agreement at any time
upon at least 60 days written notice to New Ametek; however, no such
termination by the Company shall limit New Ametek's right to terminate this
Agreement as provided above.
 
  11. Post-Termination Obligations. Upon termination of this Agreement, the
Company shall, subject to a 180-day sell-off period, cease all use of the
Marks or any term confusingly similar thereto and shall cease selling any
remaining inventory bearing the Marks and (at New Ametek's option) destroy,
modify (with New Ametek's consent) or surrender to New Ametek all signs,
letterhead, product name plates and other materials in the Company's
possession, custody or control which use the Marks or any term confusingly
similar thereto so as to cease using the Marks or any term confusingly similar
thereto. The Company acknowledges that all rights in, to and under the Marks
and the goodwill connected therewith shall remain the property of New Ametek.
Upon termination and/or expiration of this Agreement for any reason, the
Company will, subject to a 180-day sell-off period, promptly discontinue the
use of the Marks, whether as a trademark, service mark or trade name and will
not resume the use of the same or adopt any mark confusingly similar thereto;
provided that nothing herein shall prohibit resales by customers of the
Company of Products sold by the Company prior to the end of the 180 day sell-
off period.
 
  12. New Ametek's Rights. All use of the Marks by the Company and in any

  (a) The Company agrees to indemnify and hold harmless New Ametek and each of
its shareholders, officers, directors, employees and agents against any and
all liability, claims, causes of action, suits, damages and expenses for which
they or any of them may become liable or may incur or be compelled to pay in
any action or claim against them or any of them by any party, other than New
Ametek, its officers, directors, employees or agents, for or by reason of (i)
the infringement of patents, trade secret rights or rights to any intellectual

any of its agents, representatives, contractors, sublicensees or assigns with
respect to the Products, or (iv) the breach, in any material respect, by the
Company of any of its representations, warranties or covenants in this
Agreement. New Ametek shall give the Company written notice of any such claim
promptly following its receipt thereof. The Company shall have the opportunity
to undertake and to control the defense and settlement thereof through
attorneys selected by the Company after notice to and consultation with New
Ametek and good faith negotiations regarding alternative counsel if New Ametek
has reasonable objections to the Company's choice of counsel. Notwithstanding
the foregoing, the Company shall not, without the consent of New Ametek, which
consent shall not be unreasonably withheld or delayed, settle or compromise

                                     B4-4
<PAGE>

such claim and shall have the right to participate in (but not to control) any
such defense through counsel of its own choice, but at New Ametek's own
expense. If the Company elects not to undertake the defense of any such claim,
it will be responsible for reimbursing New Ametek for any expenses reasonably
incurred by New Ametek, including but not limited to reasonable attorneys',
accountants', and other experts' fees and expenses in the investigation,
defense and settlement of such claim and in enforcing its rights pursuant to
this Section 14(a), in addition to any damages ultimately awarded against New
Ametek.
 
  (b) Without limiting the indemnification provided in Section 14(a) above,
the Company agrees to carry and maintain, throughout the term of this
Agreement and for five years thereafter, with an insurance carrier authorized
to do business in the State of New York and having a rating of A VI or better
according to Best's Insurance Reports, a broad form Comprehensive General
Liability Insurance Policy or, if such policy is not reasonably available,
such other policy as would provide substantially the same protection to the
Company and New Ametek written on an occurrence basis covering the Company's
activities with respect to the Products which includes but is not limited to
coverage for contractual liability, premises operations, products liability,
personal injury and advertising injury liability and broad form property
damage liability, which shall provide protection to New Ametek of at least Two
Million Dollars ($2,000,000) per occurrence and in the aggregate; provided
that the Company may have a deductible or self-insured retainage in an amount
of not in excess of $500,000. The Company shall have New Ametek named as an
additional insured on such policies. The Company shall, within thirty (30)
days after the date thereof, provide to New Ametek a certificate of such
insurance from the insurance carrier which sets forth the scope of coverage

the Company shall provide New Ametek with a certificate of insurance
evidencing that a new insurance policy with the same coverage and terms
described above will be in place prior to such termination. Upon reasonable
request by New Ametek during the Initial Term and each Renewal Term, the
Company shall deliver to New Ametek evidence in form and substance reasonably
satisfactory to New Ametek, of the maintenance and renewal of the required
insurance, including without limitation, renewal certificates and copies of
those portions of policies, riders and endorsements pertaining to this
Agreement. Any insurance policy purchased by or carried by New Ametek shall
not be required to contribute in case of any loss by any third party,
including New Ametek or the Company, relating to the Products and either the
certificate of insurance to be provided hereunder or an endorsement to such
policy shall so state.
 
  (c) New Ametek agrees to indemnify and hold harmless the Company and each of
its shareholders, officers, directors, employees and agents against any and
all liability, claims, causes of action, suits, damages and expenses for which
they or any of them may become liable or may incur or be compelled to pay in
any action or claim against them or any of them by any party, other than the
Company, its officers, directors, employees or agents, for or by reason of (i)
the infringement of the Mark(s), as a result of the manufacture, warehousing,
marketing, promotion, publicity, advertising, sale or distribution of the
Products by New Ametek or the Company or any of its agents, representatives,
contractors, sublicensees or assigns, (ii) any acts, whether of omission or
commission, that may be committed or suffered by New Ametek or any of their
agents, representatives, contractors, sublicensees or assigns in connection
with this Agreement, or (iii) the breach, in any material respect, by New
Ametek of any of its representations, warranties or covenants in this
Agreement. The Company shall give New Ametek written notice of any such claim
promptly following its receipt thereof. New Ametek shall have the opportunity
to undertake and to control the claim and settlement thereof through attorneys
selected by New Ametek after notice to and consultation with the Company and
good faith negotiations regarding alternative counsel if the Company has
reasonable objections to New Ametek's choice of counsel. Notwithstanding the
foregoing, New Ametek shall not, without the consent of the Company, which
consent shall not be unreasonably withheld or delayed, settle or compromise
any claim or consent to the entry of any judgment which settlement, compromise
or judgment would materially and adversely affect the Company. The Company
will cooperate with New Ametek in the investigation, defense and settlement of
any such claim and shall have the right to participate in (but not to control)
any such defense through counsel of its own choice, but at the Company's own
expense. If New Ametek elects not to undertake any such claim, it will be
responsible for reimbursing the Company for
 
                                     B4-5
<PAGE>
 
any expenses reasonably incurred by the Company, including but not limited to
reasonable attorneys', accountants', and other experts' fees and expenses in
the investigation, defense and settlement of such claim and in enforcing its
rights pursuant to this Section 14(a), in addition to any damages ultimately
awarded against the Company.
 
  (d) Nothing contained in this Section 14 shall in any way diminish the
indemnifications provided for in the Indemnification Agreement, dated as of
the date hereof between Culligan, the Company and New Ametek.
 
  15. Infringement. (a) The Company agrees that if during the term of this
Agreement, any Mark shall in the opinion of the Company be infringed or used
without authorization by any other person, firm, corporation or other entity,
New Ametek shall have the sole and exclusive right, but not the obligation, to
take any and all steps in its name, or in the name of the Company or in their
joint names, as New Ametek (in its sole discretion) may deem advisable,
including, without limitation, the institution of any action or proceeding to
seek damages for and/or to enjoin such infringement or unauthorized use, and
to prosecute, settle, compromise or otherwise dispose of the same.
Notwithstanding the foregoing, the Company shall have an opportunity to
participate in the decision-making process related thereto, but the final
decision shall be controlled by New Ametek. In the event of any such action or
proceeding, the Company agrees to execute any and all papers deemed necessary
or advisable by counsel for New Ametek and, at New Ametek's expense (except in
the case of an action or proceeding taken or initiated by the Company), to do
whatever else may be deemed necessary or advisable by such counsel to assist
in the prosecution of such action or proceeding. If New Ametek elects not to
undertake any such claim, the Company, at its sole expense, may institute any
action or proceeding to seek damages for and/or to enjoin such infringement or
unauthorized use, and to prosecute, settle, compromise or otherwise dispose of
the same. In the event of any such action or proceeding, New Ametek agrees to
execute any and all papers deemed necessary or advisable by counsel for the
Company and, at the Company's expense (except in the case of an action or
proceeding taken or initiated by New Ametek), to do whatever else may be
deemed necessary or advisable by such counsel to assist in the prosecution of
such action or proceeding.
 
  (b) The party bearing the cost in connection with any such action shall be
entitled to the full recovery of any money or other property collected by way
of judgment, settlement (whether prior to or after institution of any action
or proceeding) or otherwise in connection with any such action except to the
extent of actual damages suffered by the party not bearing the cost.
 
  (c) In the event that the Company is made a party defendant in any action or
proceeding for infringement based on or arising from the use during the term
hereof of any Mark on or in connection with the Products, then the Company
shall promptly give written notice to New Ametek thereof and New Ametek shall
have the right to join in the defense of such action or proceeding at its own
cost and expense and, at its option, the Company may take over, on behalf and
in the name of the Company, the conduct of the defense of such action or
proceeding.
 
  16. No Agency. Nothing in this Agreement shall constitute the parties hereto
as principal and agent, partners or joint venturers for any purpose and the
Company shall have no power or authority to bind New Ametek or to incur any
obligations on New Ametek's behalf.
 
  17. Miscellaneous.

Board of Directors
AMETEK, Inc.
Station Square
Paoli, PA 19301
 
Ladies and Gentlemen:
 
  You have requested our opinion as to the fairness to the holders of the
outstanding shares of Common Stock, par value $0.01 per share (the "Shares"),
of AMETEK, Inc. (the "Company") of the Exchange Ratio (as defined below) to be
received for each Share pursuant to the Agreement and Plan of Merger and
Reorganization (the "Merger Agreement" and, together with the ancillary
agreements thereto, the "Agreement"), dated as of February 5, 1997 by and
among Culligan Water Technologies, Inc. ("Culligan"), Culligan Water Company,
Inc. ("Merger Sub"), Ametek Aerospace Products, Inc. ("Spinco") and the
Company. Pursuant to the Merger Agreement, Merger Sub shall be merged with and
into the Company (the "Merger"). Prior to the effectiveness of the Merger,
pursuant to a Contribution and Distribution Agreement, dated as of February 5,
1997 (the "Contribution Agreement") among the Company and Spinco, the Company
will contribute (the "Contribution") all of its assets other than the Retained
Assets (as defined in the Contribution Agreement) to Spinco, and Spinco will
assume all of the liabilities of the Company other than the Retained
Liabilities (as defined in the Contribution Agreement); Spinco's Common Stock
(the "Spinco Common Stock") will then be distributed pro rata to holders of
Shares (the "Distribution"). In the Merger, each issued and outstanding Share
will be canceled and converted into the right to receive that number of shares
(the "Exchange Ratio") of Common Stock, par value $0.01 per share (the
"Culligan Common Stock") of Culligan determined by dividing (i) (a) the Net
Equity Value (as defined in the Merger Agreement) divided by (b) $37.50 by
(ii) the number of Shares outstanding at the Effective Time (as defined in the
Merger Agreement).
 
  Goldman, Sachs & Co., as part of its investment banking business, is
continually engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings,
competitive biddings, secondary distributions of listed and unlisted
securities, private placements and valuations for estate, corporate and other
purposes. We are familiar with the Company having provided certain investment
banking services to the Company from time to time, including having acted as
sole underwriter of the Company's offering, in March 1994, of 9 3/4% Senior
Notes 2004. We also have provided certain investment banking services to
Culligan from time to time, including having acted as managing underwriter of
Culligan's initial public offering in December 1995 and of a secondary sale of
Culligan Common Stock in October 1996, and we may provide investment banking
services to each of the Company and Culligan in the future.
 
  In connection with this opinion, we have reviewed, among other things, the
Agreement; Annual Reports to Stockholders and Annual Reports on Form 10-K of
the Company for the five years ended December 31, 1995 and, in the case of
Culligan, for the fiscal year ended January 31, 1996; Culligan's Prospectuses,
dated December 14, 1995 and October 7, 1996; certain interim reports to
stockholders of the Company and Culligan and certain Quarterly Reports on Form
10-Q of the Company and Culligan; certain other communications from the
Company and Culligan to their respective stockholders; and certain internal
financial analyses and forecasts for the businesses that will remain with the
Company after the distribution of Spinco (the "Retained Business") prepared by
the Company's management. We also have held discussions with certain members
of the management of the Company, the Retained Business and Culligan regarding
the past and current business operations, financial condition and future
prospects of the Retained Business and Culligan respectively. In
 
                                      C-1
<PAGE>
 
addition, we have reviewed the reported price and trading activity for the
Culligan Common Stock, compared certain financial and stock market information
for the Retained Business with similar information for certain companies the
securities of which are publicly traded, reviewed the financial terms of
certain recent business combinations in the water filtration industry
specifically and in other industries generally and performed such other
studies and analyses as we considered appropriate.
 
  We have relied upon the accuracy and completeness of all of the financial
and other information reviewed by us, and have assumed such accuracy and
completeness for purposes of this opinion. In addition, we have not made an
independent evaluation or appraisal of the assets and liabilities of the
Retained Business or Culligan or any of its subsidiaries and we have not been
furnished with any such evaluation or appraisal. We have not been asked to
solicit, and accordingly, we have not solicited, third parties with respect to
a potential alternative transaction. We have assumed, with your consent, that
the Merger will be tax-free to the Company. Our opinion expressed herein is
provided for the information and assistance of the Board of Directors of the
Company in connection with its consideration of the Exchange Ratio and does
not constitute a recommendation to any holder of Shares as to how such holder
of Shares should vote on the proposed transaction.
 
  Based upon and subject to the foregoing and based upon such other matters as
we consider relevant, it is our opinion that as of the date hereof the
Exchange Ratio pursuant to the Merger Agreement is fair to the holders of the
Shares.
 
                                          Very truly yours,
 
                                          /s/ Goldman, Sachs & Co.

481 of the Code resulting from a change in accounting method.

                             FILING OF TAX RETURNS
 
  2.1. Preparation of Tax Returns.
 
  (a) Consistent with Agreements. Each of the parties to this Agreement agrees
to, and to cause each of its relevant Affiliates to, report the Contribution
and Distribution as transactions described in Sections 355 and 368(a)(l)(D) of
the Code and the Merger as a "reorganization" under Section 368(a)(1)(B) of

inconsistent therewith or with the consummation of such transactions as set
forth in the Merger Agreement, the Distribution Agreement, the Acquiror's Tax
Representation Letter, Spinco's Tax Representation Letter or the Private
Letter Ruling Request (in the absence of a controlling change in law or
circumstance). The parties agree that consistent with the principles of
Section 381 of the Code and with applicable law, Spinco and only Spinco shall
reflect any Tax Item arising in or attributable to a Tax-Indemnification
Period on its own Tax Returns following the Distribution Date.
 
 
  (b) Consistent with Past Practice. Except for any accounting method changes
pursuant to applications that are approved by the IRS and reflected in
Schedule 4.15 of the Merger Agreement and any accounting method elections and
changes that may be effective as of the day after the Distribution Date and
are applicable only to the Spinco Group (or otherwise have no adverse affect
on the Company Group, as determined by the Company Group in its reasonable
discretion), all Tax Returns described in Sections 2.2(a), (b), (c) and (d)
hereof filed after the date of this Agreement, in the absence of a controlling
change in law or circumstance, shall be prepared on a basis consistent with
the elections, accounting methods, conventions and principles of taxation used
for the most recent taxable periods for which Tax Returns involving similar
Tax Items have been filed and in a manner
 
                                      D-4
<PAGE>
 
that does not unreasonably accelerate deductions or defer income between Tax
Indemnification Periods and Post-Tax Indemnification Periods. Subject to the
provisions of this Agreement, all decisions relating to the preparation of Tax
Returns shall be made in the sole discretion of the party responsible under
this Agreement for such preparation.
 
  (c) Spinco Obligations. Spinco agrees to cooperate in good faith with the
Company to determine the appropriate amount of Tax Items attributable, if any,
to the Company Group to be reflected on any Tax Returns for Straddle Periods
to be prepared and filed by Spinco in accordance with Section 2.2. With
respect to each of the 1996 taxable year and the taxable year ending on and
including the Distribution Date, (i) Spinco will deliver to the Company at
least 60 days prior to the filing of the Tax Returns for such taxable year, a
pro forma Federal and state Income Tax Return (the "Pro Forma Tax Returns")
prepared on the assumption that the Project J Division is a separate taxpayer
and including only those tax items relating to the Project J Division for such
taxable years and (ii) will consult with the Company with respect to the
application of the Tax Items shown on the Pro Forma Tax Returns to the Tax
Items to be shown on the Tax Returns. The computations made with respect to
the Pro Forma Tax Returns shall be made, where applicable, on a basis
consistent with the principles of Treasury Regulation Section 1.1502-76(b)(2).
Spinco will inform and consult with the Company regarding any Tax Audits or
any other adjustments which would materially affect any of the Tax Items shown
on the Pro Forma Tax Returns. Spinco will provide the Company with copies of
all Tax Returns described in Section 2.2(a), (b) and (c) promptly after
filing.
 
  (d) Company Obligations. The Company agrees to cooperate in good faith with
Spinco to determine the appropriate amount of Tax Items attributable to the
Spinco Group to be reflected on any Tax Returns for Straddle Periods to be
prepared and filed by the Company in accordance with Section 2.2. The Company
further agrees to provide Spinco with a copy of each such Tax Return at least
30 days before it is filed and to follow the procedures in Section 4.2
relating to the calculation of Taxes and to not file any such Tax Returns
without the prior written consent of Spinco, which consent shall not be
unreasonably withheld. If such consent is withheld, Spinco shall so notify the
Company at least 10 days prior to the due date for filing such Tax Returns
(giving effect to applicable extensions). The Company will promptly provide
Spinco with copies of all such Tax Returns after filing.
 
  2.2. Filing of Tax Returns.
 
  (a) Consolidated Federal Tax Returns. The Consolidated Federal Tax Returns
required to be filed after the date hereof shall be prepared and filed or
caused to be prepared and filed by Spinco.
 
  (b) Pre-Distribution Period Tax Returns. All Tax Returns other than those
described in Section 2.2(a) which include a member of the Spinco Group or the
Company Group that are required to be filed for any Pre-Distribution Taxable
Period shall be prepared and filed or caused to be prepared and filed by
Spinco.
 
  (c) Spinco Straddle Period Tax Returns. All Tax Returns other than those
described in Section 2.2(a) which are required to be filed by any member of
the Spinco Group for any Straddle Period shall be prepared and filed or caused
to be prepared and filed by Spinco.
 
  (d) Company Straddle Period Tax Returns. All Tax Returns other than those
described in Section 2.2(a) which are required to be filed by any member of
the Company Group for any Straddle Period shall be prepared and filed or
caused to be prepared and filed by the Company.
 
  (e) Post-Distribution Period Tax Returns. All Tax Returns for all Post-
Distribution Taxable Periods shall be the responsibility of the Spinco Group
if such Tax Returns relate to a member or members of the Spinco Group or their
respective assets or businesses, or shall be the responsibility of the Company
Group if such Tax Returns relate to a member or members of the Company Group
or their respective assets or businesses.
 
  2.3. Procedures for Filing Tax Returns.
 
  (a) Designation. The Company hereby irrevocably designates, and agrees to
cause each of its Affiliates to so designate, Spinco as its agent to take any
and all actions necessary or incidental to the preparation and filing
 
                                      D-5
<PAGE>
 
of the Tax Returns described in Sections 2.2(a), (b) and (c). Spinco hereby
irrevocably designates, and agrees to cause each of its Affiliates to so
designate, the Company as its agent to take any and all actions necessary or
incidental to the preparation and filing of the Tax Returns described in
Section 2.2(d).
 
  (b) Closing of Straddle Period. To the extent permitted by law or
administrative practice, the taxable year of any member of the Company Group
which includes the Distribution Date shall be treated as closing on (and
including) the Distribution Date. The Company, Acquiror, Spinco and their
respective Affiliates agree to treat, on all Tax Returns and in all Tax Audit
Proceedings, the Affiliated Group as terminating for Federal income tax
purposes as a result of the Merger.
 
                                  ARTICLE III
 
                               PAYMENT OF TAXES

or cause to be paid, on a timely basis, all Taxes due with respect to the Tax
Returns described in Sections 2.2(a) and 2.2(b).
 
  (b) Separate Straddle Period Tax Liabilities. (i) Spinco Liability. Except

timely basis, all Taxes due with respect to the Tax Returns described in
Section 2.2(d). Spinco shall pay directly to or at the direction of the
Company, at least two days prior to the date payment (including estimated
payment) thereof is due, the Spinco Group's allocable share (as determined
under Section 4.1) of those Taxes due.
 
  (c) Post-Distribution Period Tax Liabilities. Except as otherwise provided
in this Agreement, all Taxes for all Post-Distribution Taxable Periods shall
be paid or caused to be paid by the party responsible under this Agreement for
filing the Tax Return pursuant to which such Taxes are due or, if no such Tax
Returns are due, by the party liable for such Taxes.
 
  3.2. Tax Refunds and Carrybacks
 
  (a) Retention and Payment of Tax Refunds. Except as otherwise provided in
this Agreement, Spinco shall be entitled to retain, and to receive within ten
days after Actually Realized by the Company Group, the portion of all Tax
Refunds of Taxes for which the Spinco Group is liable pursuant to Section 3.1
or Section 5.1(a), and the Company shall be entitled to retain, and to receive
within ten days after Actually Realized by the Spinco Group, the portion of
all Tax Refunds of Taxes for which the Company Group is liable pursuant to
Section 3.1 or Section 5.1(b). Notwithstanding the foregoing, (i) all Tax
Refunds resulting from the carryback of any Company Tax Item arising in a
Post-Tax Indemnification Period to a Tax Indemnification Period shall be for
the account and benefit of the Company Group and, if and to the extent
Actually Realized by Spinco, Spinco shall pay over to the Company any such Tax
Refund within ten days after it is Actually Realized by Spinco or any member
of the Spinco Group, (ii) all Tax Refunds resulting from (A) the carryback of
any Spinco Tax Item arising in a Post-Tax Indemnification Period to a Tax
Indemnification Period, or (B) with respect to each Retained Option, up to the
Retained Option Amount corresponding to such Retained Option, the Tax Items
that would have been attributable to such Retained Option had the Retained
Option been exercised on the date of the Merger, shall be for the account of
Spinco and, if and to the extent Actually Realized by the Company, the Company
shall pay over to Spinco any such Tax Refund within ten days after it is
Actually Realized by the Company or any member of the Company Group and (iii)
all Tax Refunds resulting from the utilization of any Tax Items (such as the
utilization of a minimum or foreign tax credit or Section 481(a) adjustments
which
 
                                      D-6
<PAGE>
 
reduces current year Taxes) of the Company or its Affiliates arising in a Tax
Indemnification Period shall be for the account of Spinco and, if and to the
extent Actually Realized by the Company, the Company shall pay over to Spinco
any such Tax Refund within ten days after it is Actually Realized by the
Company or any member of the Company Group. In computing the amount of any Tax
Refunds described in (i), (ii) or (iii) above, the party paying over such Tax
Refunds shall be deemed to recognize all other items of income, gain, loss,
deduction or credit before the utilization of any Tax Item causing a Tax
Refund described in this Section 3.2(a). Spinco, Acquiror, the Company and
their respective Affiliates will use their best efforts to claim and utilize
the Tax Items referred to in (i), (ii) or (iii) in a manner which is designed
to maximize (on a present value basis) the Tax Refunds described therein.
 
  (b) Refund Claims. Spinco shall be permitted to file at Spinco's sole
expense, and the Company shall reasonably cooperate with Spinco in connection
with, any claims for Tax Refund to which Spinco is entitled pursuant to this
Section 3.2 or any other provision of this Agreement. Spinco shall reimburse
the Company for any reasonable out-of-pocket costs and expenses incurred by
any member of the Company Group in connection with such cooperation. The
Company shall be permitted to file at the Company's sole expense, and Spinco
shall reasonably cooperate with the Company in connection with, any claims for
Tax Refund to which the Company is entitled pursuant to this Section 3.2 or
any other provision of this Agreement. The Company shall reimburse Spinco for
any reasonable out-of-pocket costs and expenses incurred by any member of the
Spinco Group in connection with such cooperation.
 
  Any claim for a Tax Refund under Section 3.2(b) to which Spinco is entitled
and which relates to a Tax Return for which the Company is required to file
under Section 2.2 shall be subject to the Company Group's consent (such
consent not to be unreasonably withheld). Any claim for a Tax Refund under
Section 3.2(b) to which the Company Group is entitled shall be subject to the
Spinco Group's consent (such consent not to be unreasonably withheld). A copy
of a claim for any Tax Refund to which either party is entitled to file under
Section 3.2(b) shall be provided to the other party no later than 30 days
prior to the filing of such Tax Refund claim.
 
  In the event that Spinco and the Company are each entitled to file a Tax
Refund claim pursuant to Section 3.2(b) for the same period, such Tax Refunds
of the Company and Spinco shall be allocated, in a manner analogous to
Treasury Regulation Section 1.1552-1(a)(2), to the Company and Spinco on the
basis of the percentage of the total Tax Refund which the Tax Refund of the
Company or Spinco if computed on a separate return would bear to the total
amount of the Tax Refunds for the Company and Spinco so computed.
 
                                  ARTICLE IV
 
                      ALLOCATION AND CALCULATION OF TAXES
 
  4.1. Allocations. In the case of any Tax Return described in Section 2.2(d),
the Spinco Group will be allocated the portion of such Taxes due with respect
to such Tax Return attributable to the period up to and including the
Distribution Date. This amount shall be computed (i) in the case of periodic
Taxes that are not based on income or receipts (e.g., property taxes), by
allocating to the Spinco Group a portion of such Taxes based on the ratio of
the number of days in the Straddle Period prior to and including the
Distribution Date to the total number of days in the Straddle Period and (ii)
in the case of all other Taxes, as if such taxable period ended on and
included the Distribution Date and, in the case of any Taxes attributable to
the ownership of any equity interest in any partnership or other "flow-
through" entity, as if a taxable period of such partnership or other "flow-
through" entity ended on and included the Distribution Date. Spinco will
determine the allocations for this Section in a manner consistent with the
principles set forth in Section 4.2.
 
  4.2. Calculations and Determinations. All calculations and determinations
required to be made pursuant to this Agreement (including the calculation in
Section 4.1) shall be made in good faith by the party making such calculations
or determinations. Except for any accounting method changes pursuant to
applications for accounting method changes filed prior to the date hereof and
any accounting method elections and changes that
 
                                      D-7
<PAGE>
 
may be effective as of the day after the Distribution Date, all calculations
and determinations required to be made pursuant to this Agreement (including
the calculation in Section 4.1), shall be made, in the absence of a
controlling change in law or circumstance, on a basis consistent with the
elections, accounting methods, conventions and principles of taxation used for
the most recent taxable periods for which Tax Returns involving similar Tax
Items have been filed and in a manner that does not unreasonably accelerate
deductions or defer income between Tax Indemnification Periods and Post-Tax
Indemnification Periods.
 
  4.3. Principles of Determination. In implementing this Agreement, except as
otherwise specifically provided, the parties shall make any adjustments that
are necessary to ensure that, with respect to Taxes for Straddle Periods or
Pre-Distribution Taxable Periods, payments and reimbursements between the
parties reflect the principles that the Company is to bear responsibility only
for Taxes for the Company Group (and any Affiliates) that are attributable to
the portion of any Straddle Period after the Distribution Date (calculated by
treating the day after the Distribution Date as the first day of a taxable
period) and that (i) Spinco is to bear responsibility for all other Taxes for
Straddle Periods and Pre-Distribution Taxable Periods, (ii) Spinco is to be
entitled to any Tax Refunds relating to Tax Items attributable to Tax
Indemnification Periods and (iii) Spinco is to be entitled to any Tax Refunds
(up to the Retained Option Amount) relating to Tax Items that would have been
attributable to the Retained Options had the Retained Options been exercised
on the Merger Date.

                       TAX INDEMNIFICATION; TAX CONTESTS
 
  5.1. Indemnification.
 
  (a) Spinco Indemnification. Except as otherwise provided in Section 5.1(b),
Spinco and the Spinco Group shall be liable for and shall indemnify, defend
and hold harmless the members of the Company Group and Acquiror and each of
their respective Affiliates and representatives from and against (A) all Taxes
of the Company Group and the Spinco Group for Pre-Distribution Taxable Periods
(B) all Taxes of the Company Group and the Spinco Group for the portion of any
Straddle Period ending on and including the Distribution Date, (C) all Taxes
of the Spinco Group for the portion of any Straddle Period beginning on the

result of Treasury Regulation Section 1.1502-6(a) or a comparable state, local
or foreign law) for Income Taxes of any person (other than a member of the
Company Group or the Spinco Group) which is or has ever been affiliated with
any member of the Company Group or the Spinco Group or with which any member
of the Company Group or the Spinco Group joins or has ever joined (or is or
has ever been required to join) in filing any consolidated, combined or
unitary Tax Return for any Pre-Distribution Taxable Period or Straddle Period,
(F) all Taxes for which Spinco is liable pursuant Section 5.5, (G) all Taxes
for any taxable period (whether beginning before, on or after the Distribution
Date) that would not have been payable but for the breach by any member of the
Spinco Group of any representation, warranty or obligation under this
Agreement or the Merger Agreement, (H) all liability for Taxes resulting from
the Contribution, Distribution and/or Merger (but not including (i) any
periodic Taxes that are not based on income or receipts attributable to
collateral consequences of such transactions, such as a reassessment of
Company Group property for property Tax purposes resulting from the change in
control incident to the Merger and (ii) Taxes, if any, attributable to
payments made to the Company in the form of "true-ups" or other purchase price
adjustments pursuant to the terms of the Merger Agreement) other than
liability arising from an Action, as defined in Section 5.5(b), (I) all Taxes
of the Company Group attributable to the recapture of any inventory reserves
of the Company Group, whether pursuant to a change in accounting method or

Section 1.9(b) of the Distribution Agreement and (K) all liability for any
reasonable legal, accounting, appraisal, consulting or similar fees and
expenses relating to the foregoing.
 
  (b) Company and Acquiror Indemnification. Except as otherwise provided in
Section 5.1(a), the Company and Acquiror shall be liable for and shall
indemnify, defend and hold harmless the Spinco Group from and
 
                                      D-8
<PAGE>
 
against (A) all Taxes of the Company Group for Post-Distribution Taxable
Periods, (B) all Taxes of the Company Group for the portion of any Straddle
Period beginning on the day after the Distribution Date (calculated by
treating the day after the Distribution Date as the first day of a taxable
period), (C) all Taxes for which the Company is liable pursuant to Section
5.5, (D) all Taxes for any taxable period (whether beginning before, on or
after the Distribution Date) that would not have been payable but for the
breach by any member of the Company Group of any representation, warranty or

Group's share of any Transfer Taxes, as provided in Section 1.9(b) of the
Distribution Agreement and (F) all liability for any reasonable legal,
accounting, appraisal, consulting or similar fees and expenses relating to the
foregoing.
 
  (c) Joint Indemnification. Notwithstanding anything to the contrary
contained herein, in the event that Spinco and the Company would each be
liable for Taxes resulting from the Contribution, Distribution and/or the
Merger pursuant to Section 5.1(a) and 5.1(b) (without regard to any action
taken by the other party), Spinco and the Company shall each be liable for one
half of such Taxes and shall indemnify each other for any excess of such
amount paid, in the aggregate, to any one or more Taxing Authorities.
 
  (d) Payments. Subject to Section 5.6(b), any indemnity payment required to
be made pursuant to this Section 5.1 shall be paid within thirty days after
the indemnified party makes written demand upon the indemnifying party, but in
no case earlier than five business days prior to the date on which the
relevant Taxes are required to be paid (or would be required to be paid if no
such Taxes are due) to the relevant Taxing Authority.
 
  5.2. Notice of Indemnity. Whenever a party hereto (hereinafter an
"Indemnitee") becomes aware of the existence of an issue raised by any Taxing
Authority which could reasonably be expected to result in a determination that
would increase the liability for any Tax of the other party hereto or any
member of its Group for any Post-Tax Indemnification Period (in the case of
the Company Group) or for any Tax Indemnification Period (in the case of the
Spinco Group) or require a payment hereunder to the other party (hereinafter
an "Indemnity Issue"), the Indemnitee shall in good faith promptly give notice
to such other party (hereinafter the "Indemnitor") of such Indemnity Issue.
The failure of any Indemnitee to give such notice shall not relieve any
Indemnitor of its obligations under this Agreement except to the extent such
Indemnitor or its Affiliate is actually materially prejudiced by such failure
to give notice.
 
  5.3. Tax Contests. The Indemnitor and its representatives, at the
Indemnitor's expense, shall be (A) entitled to participate in all conferences,
meetings or proceedings with any Taxing Authority, the subject matter of which
is or includes an Indemnity Issue, (B) entitled to participate in all
appearances before any court, the subject matter of which is or includes an
Indemnity Issue, and (C) required to consent (which consent shall not be
unreasonably withheld) to the settlement of all Tax Audits pertaining to or
including an Indemnity Issue. Subject to the Indemnitor's right to consent
(which consent shall not be unreasonably withheld) to the settlement of all
Tax Audits pertaining to or including an Indemnity Issue, the party who has
responsibility for filing the Tax Return under this Agreement (the
"Responsible Party") with respect to which there could be an increase in
liability for any Tax or with respect to which a payment could be required
hereunder shall have the right to decide as between the parties hereto how
such matter is to be dealt with and shall control all audits and similar
proceedings. If no Tax Return is or was required to be filed in respect of an
Indemnity Issue, the Indemnitor shall be treated as the Responsible Party with
respect thereto. The Responsible Party agrees to cooperate in the settlement
of any Indemnity Issue with the other party and to take such other party's
interests into account. If the Indemnitor is not the Responsible Party, such
cooperation may include permitting the Indemnitor, at the Indemnitor's sole
expense, to litigate or otherwise resolve any Indemnity Issue. Notwithstanding
any other provision of this Agreement, if Spinco has materially satisfied its
obligations under this Agreement and if the Company fails to permit Spinco to
control any Indemnity Issue (other than an Indemnity Issue resulting solely
from an Action) relating to the qualification of the Contribution and
Distribution as transactions described in Sections 355 and 368(a)(1)(D) of the
Code or the qualification of the Merger as a "reorganization" within the
meaning of Section 368(a)(1)(B) of the Code, then Spinco shall not be liable
for and shall not indemnify the Company Group for any Tax Deficiency resulting
from an adverse determination of such Indemnity Issue.
 
                                      D-9
<PAGE>
 
Notwithstanding anything to the contrary contained in this Section 5.3, any
Indemnity Issue involving the qualification of the Contribution and the
Distribution as transactions described in Sections 355 and 368 (a)(1)(D) of
the Code or the Merger as a "reorganization" described in Section 368(a)(1)(B)
of the Code, that (i) relates solely to an Action shall be controlled solely
by the Company (and no consent of Spinco shall be required with respect to any
settlement of such Indemnity Issue), (ii) relates solely to circumstances
other than an Action shall be controlled solely by Spinco (and no consent of
the Company shall be required with respect to any settlement of such Indemnity
Issue) and (iii) relates to circumstances described in both (i) and (ii) above
shall be jointly controlled by the Company and Spinco.
 
  5.4. Timing Adjustments.
 
  (a) Timing Differences. If a Tax Audit Proceeding or an amendment of a Tax
Return results in a Timing Difference, and such Timing Difference results in a
decrease in an indemnity obligation Spinco has or would otherwise have under
Section 5.1 and/or an increase in the amount of a Tax Refund to which Spinco
is entitled under Section 3.2, then in each Post-Tax Indemnification Period in
which the Company Group Actually Realizes an Income Tax Detriment, Spinco
shall pay to the Company an amount equal to such Income Tax Detriment;
provided, however, that the aggregate payments which Spinco shall be required
to make under this Section 5.4(a) with respect to any Timing Difference shall
not exceed the aggregate amount of the Income Tax Benefits realized by the
Spinco Group for all taxable periods and the Company Group for all Tax
Indemnification Periods as a result of such Timing Difference. Spinco shall
make all such payments within ten days after the Company notifies Spinco that
the relevant Income Tax Detriment has been Actually Realized.
 
  (b) Reverse Timing Differences. If a Tax Audit Proceeding or an amendment of
a Tax Return results in a Reverse Timing Difference, and such Reverse Timing
Difference results in an increase in an indemnity obligation of Spinco under
Section 5.1 and/or a decrease in the amount of a Tax Refund to which Spinco is
or would otherwise be entitled to under Section 3.2, then in each Post-Tax
Indemnification Period in which the Company Group Actually Realizes an Income
Tax Benefit, the Company shall pay to Spinco within ten days after the Company
has Actually Realized such Income Tax Benefit an amount equal to such Income
Tax Benefit; provided, however, that the aggregate payments which the Company
shall be required to make under this Section 5.4(b) with respect to any
Reverse Timing Difference shall not exceed the aggregate amount of the Income
Tax Detriments realized by the Company Group and the Spinco Group for all Tax
Indemnification Periods as a result of such Reverse Timing Difference.
 
  5.5. Certain Transactions.
 
  (a) Consistent with Representations. Spinco shall, and shall cause each
Spinco Group member to, comply with and take no action inconsistent with
Spinco's Tax Representation Letter or the Private Letter Ruling Request.
Acquiror shall, and shall cause each member of the Company Group to, comply
with and take no action inconsistent with Acquiror's Tax Representation Letter
or the Private Letter Ruling Request. The Spinco Group, Acquiror and the
Company Group shall use their respective best efforts to have the Contribution
and the Distribution qualify as transactions described in Sections 355 and 368
(a)(l)(D) of the Code and to have the Merger qualify as a "reorganization"
within the meaning of Section 368(a)(l)(B) of the Code.
 
  (b) Tax-Free Reorganization Treatment. Acquiror and the Company agree to
indemnify and hold the Spinco Group harmless from and against any Taxes
resulting from any Action (as hereinafter defined) which causes either the
Contribution and the Distribution to fail to qualify as transactions described
in Sections 355 and 368(a)(1)(D) of the Code or the Merger to fail to qualify
as a "reorganization" within the meaning of Section 368(a) (1) (B) of the
Code. An "Action" shall mean any of the actions taken by Acquiror, the Company
or any of their respective Affiliates (other than the members of the Spinco
Group) within the two-year period beginning on and continuing after the
Distribution Date which is inconsistent with Acquiror's Tax Representation
Letter or the Private Letter Ruling Request or any actions taken by Acquiror
or any of its Affiliates prior to and including the date of the Merger.
Notwithstanding the foregoing, an Action shall not include any transaction or
action disclosed or described in the Acquiror's Tax Representation Letter,
Private Letter Ruling Request or required or otherwise contemplated by the
Merger Agreement (or any agreement or document included as an
 
                                     D-10
<PAGE>
 
exhibit thereto), or of which the Company or Spinco has actual knowledge as of
the Distribution Date. An Action shall not include any action on the part of
any member of the Spinco Group, or any of their respective shareholders,
officers, directors or agents. For purposes of this Section 5.5(b), the amount
of any Taxes resulting from an Action shall equal the difference between (i)
the Taxes actually paid with respect to the Contribution, Distribution and the
Merger and (ii) the amount of Taxes that would have been payable with respect
to the Contribution, Distribution and the Merger in the absence of such
Action.
 
  5.6. Payments Net of Taxes
 
  (a) Gross Up and Characterization. The amount of any payment under this
Agreement shall be (i) increased to take account of any net Tax cost incurred
by the recipient thereof as a result of the receipt or accrual of payments
hereunder (grossed-up for such increase) and (ii) reduced to take account of
any net Tax benefit realized by the recipient arising from the incurrence or
payment of any such payment, other than any such net Tax benefit that the
recipient is specifically entitled to retain pursuant to this Agreement. In
computing the amount of any such Tax cost or Tax benefit, the recipient shall
be deemed to recognize all other items of income, gain, loss, deduction or
credit before recognizing any item arising from the receipt or accrual of any
payment hereunder. Except as provided in Section 5.6(b), or unless the parties
otherwise agree to an alternative method for determining the present value of
any such anticipated Tax benefit or Tax cost, any payment hereunder shall
initially be made without regard to this Section and shall be increased or
reduced to reflect any such net Tax cost (including gross-up) or net Tax
benefit only after the recipient has Actually Realized such cost or benefit.
It is the intention of the parties that payments made pursuant to this
Agreement are to be treated as relating back to the Contribution and
Distribution as an adjustment to the assets and liabilities contributed
thereunder, and the parties shall not take any position inconsistent with such
intention before any Taxing Authority, except to the extent that a final
determination (as defined in Section 1313 of the Code) with respect to the
recipient party causes any such payment not to be so treated.
 
  (b) Time for Payment. Notwithstanding any other provision of this Agreement,
to simplify the administration of this Agreement, the payment of any amount
less than $25,000 required to be made pursuant to this Agreement by one party
hereto to another party hereto need not be made to such other party prior to
thirty days following the later of (i) the close of the calendar quarter
during which such payment obligation arose and (ii) the day during such
calendar quarter when the aggregate amount of all such less than $25,000
payment obligations arising during such calendar quarter exceeds $150,000.
Unless otherwise specified by the recipient for items exceeding $100,000, any
such payment may be made on a net Tax basis (i.e., reduced to take account of
any net Tax benefit to be realized by the recipient (computed at an effective
Tax rate to be agreed upon from time-to-time by the parties)) to the extent
such recipient is entitled to a corresponding deduction.
 
  (c) Right to Offset. Any party making a payment under this Agreement shall
have the right to reduce any such payment by any amounts owed to it by the
other party to this Agreement.
 
                                  ARTICLE VI
 
                    COOPERATION AND EXCHANGE OF INFORMATION
 
  6.1. Cooperation and Exchange of Information. Each party hereto, on behalf
of itself and its Affiliates, agrees to provide the other parties hereto with
such cooperation and information as such other parties shall reasonably
request, and as promptly as practicable, in connection with the preparation or
filing of any Tax Return or claim for or allocation of a Tax Refund not
inconsistent with this Agreement or in conducting any Tax Audit Proceedings or
other proceeding in respect to Taxes or to carry out the provisions of this
Agreement. To the extent necessary to carry out the purposes of this Agreement
and subject to the other provisions of this Agreement, such cooperation and
information shall include without limitation the non-exclusive designation of
an officer of Spinco as an officer of the Company and Acquiror and each of
their respective Affiliates solely for the purpose of signing Tax Returns,
cashing refund checks, pursuing refund claims, dealing with Taxing Authorities
and defending Tax Audit Proceedings, in each case if such actions relate to
Tax matters pertaining to
 
                                     D-11
<PAGE>
 
or arising in the Tax Indemnification Period, as well as promptly forwarding
copies of appropriate notices and forms or other communications received from
or sent to any Taxing Authority which relate to the Tax Items on the Pro Forma
Tax Returns and providing copies of all relevant Tax Returns for the Tax
Indemnification Period, together with accompanying schedules and related
workpapers, documents relating to rulings or other determinations by Taxing
Authorities, and records concerning the ownership and Tax basis of property,
which either party may possess and which relate to the Tax Items on the Pro
Forma Tax Returns. Subject to the rights of the Company Group under the other
provisions of this Agreement, such officer shall have the authority to execute
powers of attorney (including Form 2848) on behalf of each member of the
Company Group with respect to Tax Returns and Taxes for the Tax
Indemnification Period. Each party to this Agreement shall make, or shall
cause its Affiliates to make, their employees and facilities available on a
mutually convenient basis to provide an explanation of any documents or
information provided hereunder. Any party hereto requesting cooperation or
information from the other parties hereto will reimburse such other parties
for all reasonable out of pocket expenses incurred in providing such
cooperation or assistance.
 
  6.2. Record Retention. The Company and Spinco agree to (i) retain all Tax
Returns, related schedules and workpapers, and all material records and other
documents as required under Section 6001 of the Code and the regulations
promulgated thereunder relating thereto ("Tax Records") existing on the
Distribution Date or created through the Distribution Date, for 10 years from
the Distribution Date and (ii) allow the other parties to this Agreement and
their representatives (and representatives of any of its Affiliates), at times
and dates reasonably acceptable to the retaining party, to inspect, review and
make copies of such records, and have access to such employees, as the Company
and Spinco may reasonably deem necessary or appropriate from time to time,
such activities to be conducted during normal business hours and without
disruption to the respective business of either party. At the end of the 10-
year period described in clause (i), the Company or Spinco, as the case may
be, shall transfer such records (or cause such records to be transferred) to
the other party (at such other party's sole expense), unless such other party
notifies the Company or Spinco, as the case may be, within 90 days prior to
the expiration of the 10-year period, that such other party does not desire to
receive such Tax Records, in which case the Company or Spinco, as the case may
be, may destroy or otherwise dispose of such undesired documents.
 
                                  ARTICLE VII
 
                                 MISCELLANEOUS

all of its income and other Tax Items will be included in Acquiror's
consolidated Federal Tax Returns from and after the date of the Merger.

Agreement only by written agreement executed and delivered by duly authorized

                SUBJECT TO COMPLETION, DATED JUNE 20, 1997     
 
                             INFORMATION STATEMENT

                      (To Be Renamed "AMETEK, INC.")     
 
                                  COMMON STOCK
                           (PAR VALUE $.01 PER SHARE)
          
  This Information Statement is being furnished to stockholders of AMETEK,
Inc., a Delaware corporation ("AMETEK"), in connection with the distribution by
AMETEK of all of the outstanding shares of common stock, par value $.01 per
share ("New Ametek Common Stock"), of Ametek Aerospace Products, Inc. ("New
Ametek"), a Delaware corporation and wholly owned subsidiary of AMETEK, to the
holders of common stock of AMETEK, par value $.01 per share ("AMETEK Common
Stock"), on a share for share basis (the "Spin-Off"). No consideration will be
paid by the holders of AMETEK Common Stock for the shares of New Ametek Common
Stock to be received by them in the Spin-Off. Promptly after the Spin-Off, the
corporate name of New Ametek will be changed to "AMETEK, Inc."     
 
  At the time of the Spin-Off (the "Spin-Off Date"), New Ametek will own all of
AMETEK's assets except those relating to the water filtration business of
AMETEK, which consists of AMETEK's Plymouth Products Division, and the
following three foreign subsidiaries of AMETEK: Ametek Filters, Limited, APIC
International S.A. and AFIMO S.A.M. (collectively, the "Water Filtration
Business"), and will have assumed all of AMETEK's liabilities, except for
certain liabilities relating to the Water Filtration Business and certain
indebtedness of AMETEK.
   
  The completion of the Spin-Off is a condition to the parties' obligations to
consummate the merger (the "Merger") provided for in the Amended and Restated
Agreement and Plan of Merger and Reorganization, dated as of February 5, 1997
(the "Merger Agreement"), by and among Culligan Water Technologies, Inc., a
Delaware corporation ("Culligan"), Culligan Water Company, Inc., a Delaware
corporation and a wholly owned subsidiary of Culligan ("Culligan Merger Sub"),
AMETEK and New Ametek. The Spin-Off will be effected only if all of the other
conditions to the Merger, including approval of the Spin-Off and the Merger by
the stockholders of AMETEK, have been satisfied or waived. See "THE MERGER
AGREEMENT" in the Joint Proxy Statement/Prospectus, of which this Information
Statement is Appendix E (the "Joint Proxy Statement/Prospectus"). The Spin-Off
and the Merger are intended to be tax-free.     
   
  There is currently no public trading market for the shares of New Ametek
Common Stock; however, it is expected that a "when-issued" trading market will
develop for the New Ametek Common Stock prior to the Merger. New Ametek has
applied for listing of New Ametek Common Stock on the New York Stock Exchange
(the "NYSE") and on the Pacific Exchange, Inc. (the "PCX").

                                   NEW AMETEK
 
  New Ametek was incorporated in Delaware on May 8, 1986 and has been a wholly
owned subsidiary of AMETEK since August 1989. To date, New Ametek's business
has consisted entirely of manufacturing aerospace instrumentation. Prior to the
Spin-Off, AMETEK will transfer or cause to be transferred to New Ametek all of
AMETEK's assets other than those which are part of the Water Filtration
Business, and New Ametek will assume all of AMETEK's liabilities, except for
certain liabilities relating to the Water Filtration Business and certain
indebtedness of AMETEK (collectively, the "Contributions"). See "THE
CONTRIBUTIONS AND THE SPIN-OFF--Terms of the Distribution Agreement--The
Contributions." Immediately following the Spin-Off and the Merger, New Ametek
will change its name to "AMETEK, Inc." The information in this Information
Statement assumes that the Contributions will be completed.
 
  AMETEK's products are currently produced and sold world-wide through the
following three groups:
 
  .  Electromechanical Group--fractional horsepower electric motors and
      blowers for vacuum cleaners and other floor-care products, as well as
      for appliances, lawn tools, computer equipment and other business
      machines.
 
  .  Precision Instruments Group--pressure gauges and other devices for
      measuring, monitoring and controlling industrial manufacturing
      processes and instruments for heavy vehicles, commercial and military
      aircraft and jet engines.
 
  .  Industrial Materials Group--specialty metal products for electronics,
      general industry and consumer goods, and plastic compounding for the
      automotive and housing industries; temperature and corrosion resistant
      materials. Currently, this Group also includes the Water Filtration
      Business which will not be transferred to New Ametek.
   
  New Ametek will continue operating each of these businesses except for the
Water Filtration Business. Management believes AMETEK currently is, and upon
completion of the Spin-Off, New Ametek will continue to be, a leading global
manufacturer of electrical and electromechanical products and materials
engineered for niche markets with operations in the United States, Europe, Asia
and Mexico. It is expected that approximately one-third of New Ametek's total
sales will be to international markets. AMETEK's business has grown over the
years through a focus on the manufacturing of electronic, electromechanical and
electrical products for niche markets where, based on technological or cost
advantages, AMETEK has or seeks to build a significant market share. The
management of New Ametek intends to continue this focus.

  Upon completion of the Spin-Off, substantially all of the properties and
assets of AMETEK will have been transferred to New Ametek, which will then be
an independent, publicly held company. Although the separation of AMETEK's
other businesses, operations and companies from the Water Filtration Business
has been structured as a "spin-off" of New Ametek for legal, tax and other
reasons, New Ametek will in substance be the successor to AMETEK. As the
successor to AMETEK, New Ametek will succeed to many important aspects of
AMETEK's existing businesses, organization and affairs, namely: (i) New Ametek
will be renamed "AMETEK, Inc." upon consummation of the Spin-Off and the
Merger; (ii) New Ametek will be headquartered at AMETEK's current headquarters
in Paoli, Pennsylvania; (iii) New Ametek's Board of Directors (the "New Ametek
Board") will consist of those persons currently constituting the AMETEK Board
of Directors; (iv) New Ametek's executive management will consist of the
current AMETEK executive management; and (v) the businesses to be conducted by
New Ametek will consist of AMETEK's Electromechanical, Precision Instruments
and Industrial Materials business lines, except for the Water Filtration
Business.
 
  Following completion of the Spin-Off and the Merger, the management of New
Ametek intends to reorganize the businesses of New Ametek into two groups: the
Electromechanical Group and the Electronic Instruments Group. This new
organizational structure will better reflect New Ametek's principal emphasis on
electromechanical and electronics related businesses.
 
  In November 1993, AMETEK adopted, and New Ametek will continue to implement,
a Stockholder Value Enhancement Plan (the "Plan") with the objective of
improving New Ametek's earnings growth through a combination of financial and
operating strategies. The Plan's ongoing operating strategies consist of: (i)
achieving operational excellence through improved asset management, increased
operating synergies and reduced cycle times, (ii) intensifying new product
development efforts, especially in the electric motor-blower, precision
instruments and specialty metals product lines, (iii) completing strategic
acquisitions and alliances which concentrate on enhancing New Ametek's
technological and manufacturing advantages and market position in its core
businesses, and (iv) pursuing global and market expansion, especially in Europe
and Asia.
 
  The mailing address of New Ametek's principal executive offices is Station
Square, Paoli, Pennsylvania 19301, and its telephone number is (610) 647-2121.
   
  Except for the historical information contained herein or incorporated by
reference, certain matters discussed in this Information Statement are
"forward-looking statements," as defined in the Private Securities Litigation
Reform Act ("PSLRA") of 1995, which involve risk and uncertainties that exist
in New Ametek's operations and business environment, and are subject to change
based on various important factors. Such factors include, but are not limited
to, economic conditions, market demand and financing considerations, which in
the future could cause New Ametek's actual results to differ materially from
those expressed in any forward-looking statements made by, or on behalf of, New
Ametek.

DISTRIBUTING CORPORATION....  AMETEK, Inc. References to AMETEK include its
                               subsidiaries, except where the context otherwise
                               requires.
 
DISTRIBUTED CORPORATION.....  New Ametek, which, by the Spin-Off Record Date
                               (as defined below), will hold the assets and
                               assume the liabilities of AMETEK, except those
                               assets and certain liabilities relating to the
                               Water Filtration Business and certain
                               indebtedness of AMETEK. See "THE CONTRIBUTIONS
                               AND THE SPIN-OFF--Terms of the Distribution
                               Agreement--The Contributions."
 
SHARES TO BE DISTRIBUTED....     
                              Assumed to be 32,903,451 shares of New Ametek
                               Common Stock (based on the number of shares of
                               AMETEK Common Stock outstanding on June 13,
                               1997). However, after giving effect to the
                               exercise of exercisable options to purchase
                               AMETEK Common Stock, up to an additional
                               1,290,713 shares of New Ametek Common Stock
                               could be issued in the Spin-Off. Therefore, a
                               maximum of 34,194,164 shares of New Ametek
                               Common Stock could be issued in the Spin-Off.
                                   
DISTRIBUTION RATIO..........  One share of New Ametek Common Stock for every
                               share of AMETEK Common Stock owned as of the
                               close of business on the Spin-Off Record Date.
 
FEDERAL INCOME TAX               
 CONSEQUENCES...............  The Contributions, the Spin-Off and the Merger
                               were conditioned upon the issuance by the
                               Internal Revenue Service (the "IRS") of a
                               private letter ruling (the "Private Letter
                               Ruling") reasonably satisfactory in form and
                               substance to AMETEK and Culligan substantially
                               to the effect that, on the basis of the facts,
                               representations and assumptions existing at the
                               Effective Time (as defined): (i) the
                               Contributions followed by the Spin-Off qualify
                               as a tax-free reorganization pursuant to Section
                               368(a)(1)(D) of the Internal Revenue Code of
                               1986, as amended (the "Code"); (ii) the Spin-Off
                               qualifies as a tax-free distribution pursuant to
                               Section 355(a) of the Code; and (iii) the Merger
                               qualifies as a tax-free reorganization pursuant
                               to Section 368(a)(1)(B) of the Code. The Private
                               Letter Ruling was issued on June 16, 1997. If
                               the IRS revokes the Private Letter Ruling, this
                               condition will nevertheless be satisfied if, on
                               or prior to the Closing Date, AMETEK and
                               Culligan receive the Tax Opinions (as defined)
                               to the same effect as the Private Letter Ruling.
                               See "CERTAIN FEDERAL INCOME TAX CONSEQUENCES."
                                   
TRADING MARKET..............     
                              Currently, there is no public market for New
                               Ametek Common Stock. New Ametek has applied for
                               listing of New Ametek Common Stock on the NYSE
                               and the PCX. See "LISTING AND TRADING OF NEW
                               AMETEK COMMON STOCK."     
 
OVERVIEW OF THE SPIN-OFF....  AMETEK has agreed to effect the Spin-Off prior to
                               consummating the Merger. The Contributions
                               followed by the Spin-Off will separate all of
                               AMETEK's other businesses from the Water
                               Filtration Business and enable Culligan to
                               acquire only the Water Filtration Business in
                               the Merger; the Spin-Off will leave AMETEK's
                               remaining businesses as a separate publicly held

                               holders of AMETEK Common Stock. The directors
                               and officers of AMETEK will be the directors and
                               officers of New Ametek at the time of the Spin-
                               Off. The completion of the Spin-Off is a
                               condition to the Merger.
 
                              Each holder of AMETEK Common Stock will receive
                               one share of New Ametek Common Stock for each
                               share of AMETEK Common Stock held by such
                               stockholder. AMETEK will deliver to the
                               Distribution Agent shares of New Ametek Common
                               Stock representing 100% of the outstanding

                               distribution to the holders of AMETEK Common
                               Stock as of the close of business on the Spin-
                               Off Record Date. Upon consummation of the Spin-
                               Off, the holders of AMETEK Common Stock on the
                               Spin-Off Record Date will become the
                               stockholders of New Ametek.
 
OVERVIEW OF THE MERGER......
                              In the Merger, Culligan Merger Sub will be merged
                               with and into AMETEK (which then will be
                               comprised solely of the Water Filtration
                               Business), with AMETEK being the surviving
                               corporation, becoming a wholly owned subsidiary
                               of Culligan and being renamed "Culligan Water
                               Company, Inc." immediately upon consummation of
                               the Merger. At the effective time of the Merger
                               (the "Effective Time"), each issued and
                               outstanding share of AMETEK Common Stock will be
                               converted into the right to receive the number
                               of shares of common stock, par value $.01 per

                               Statement/Prospectus), divided by (ii) $37.50,
                               divided by (iii) the number of shares of AMETEK

                               Conversion of AMETEK Common Stock" in the Joint
                               Proxy Statement/Prospectus, of which this
                               Information Statement is Appendix E.

                               terms under which AMETEK (thereafter renamed

                               years following such five-year period, New
                               Ametek will grant to AMETEK an exclusive license

RISK FACTORS................  AMETEK stockholders should carefully consider the
                               matters discussed under the section titled "Risk

                                 RISK FACTORS
 
  Prospective purchasers of New Ametek Common Stock should carefully consider
the risk factors set forth below, as well as other information contained in
this Information Statement. For purposes of this section, references herein to
"New Ametek" are references to the operations and business of AMETEK and its
subsidiaries, adjusted to reflect treatment of the Water Filtration Business
as a discontinued operation.
 
  Relationship with AMETEK. Pursuant to the Indemnification Agreement, New
Ametek has agreed to indemnify and hold harmless AMETEK and Culligan from and
against certain claims and actions related to the businesses that New Ametek
will acquire in the Spin-Off. Under the Tax Allocation Agreement, subject to
certain exceptions, New Ametek will assume responsibility for any tax
liabilities of AMETEK for the period prior to the Spin-Off, tax liabilities
resulting from the Contributions, the Spin-Off or the Merger and any tax
liabilities of New Ametek.
 
  THE FOLLOWING RISKS WHICH CURRENTLY APPLY TO AMETEK WILL CONTINUE TO APPLY
TO NEW AMETEK:
   
  Dependence on Several Customers. During the three months ended March 31,
1997, and for the years 1996 and 1995, approximately 15%, 19% and 17%,
respectively, of New Ametek's total revenues were derived from sales to New
Ametek's five largest customers. New Ametek expects that revenues from major
customers will continue to constitute significant percentages of its total
revenues for the foreseeable future. There can be no assurance, however, that
major customers will continue to purchase New Ametek's products. The loss of
revenues generated from major customers could have a material adverse effect
on the financial condition or results of operations of New Ametek.     
   
  Environmental Matters. New Ametek will be subject to environmental and
occupational health and safety laws and regulations concerning, among other
things, air emissions, discharges to waters and the generation, handling,
storage, transportation and disposal of hazardous substances and wastes.
Environmental risks are inherent in many of New Ametek's manufacturing
operations. In addition, the Comprehensive Environmental Response,
Compensation and Liability Act generally imposes joint and several liability
for clean-up costs, without regard to fault or the legality of the original
conduct, on parties contributing hazardous substances to sites designated for
clean-up under the Act. AMETEK has been named a potentially responsible party
at several sites which are the subject of government-mandated clean-ups and,
pursuant to the Distribution Agreement, New Ametek will assume responsibility
for these matters. While it is not possible to quantify the potential
financial impact of pending environmental matters, New Ametek believes that
the outcome of these matters is not likely to have a material effect on the
financial position or future results of operations of New Ametek. However,
there can be no assurance that future environmental liabilities will not occur
or that environmental damages due to prior or present practices will not
result in future liabilities. See "BUSINESS--Environmental Compliance."     
   
  Risks Associated with International Operations. During the three months
ended March 31, 1997, and for the years 1996 and 1995, approximately 19%, 17%
and 18%, respectively, of New Ametek's revenues were derived from its foreign
operations (exclusive of export sales from the United States). Such operations
are subject to the customary risks of operating in an international
environment, including the potential imposition of trade or foreign exchange
restrictions, tariff increases, fluctuations in exchange rates and unstable
political situations.     
   
  Collective Bargaining Agreements. Of New Ametek's approximately 6,200
employees at March 31, 1997, approximately 2,200 are covered by collective
bargaining agreements. New Ametek believes that its relations with its union
employees are generally good, but there is no assurance that New Ametek will
not at some point be subject to work stoppages and possibly a strike by some
of its employees and, if such events were to occur, that there could be a
material adverse effect on New Ametek's financial condition or results of
operations.     
 
  Dependence on General Economic Conditions. The demand for New Ametek's
products is subject to general economic conditions, such as rates of
inflation, fluctuations in general business conditions, governmental
regulation and the availability of financing at favorable rates, which factors
are outside the control of New Ametek. Currently, the most noticeable price
pressure is in the electronic motor market, where some competitors have
reduced prices and new competitors are seeking to gain market entry; this may
have an adverse effect on
 
                                       9
<PAGE>
 
profit margins. In addition, a cyclical downturn in the heavy vehicle industry
adversely affected 1996 sales of the Precision Instruments Group; however,
industry conditions have improved in 1997. There can be no assurance that the
current general economic conditions and strong demand in the aerospace
industry will continue.
 
  Technological Change and Product Development. Many of New Ametek's products
are characterized by rapid technological change, frequent new product
introductions and evolving industry standards. New Ametek believes that its
future success will depend on its ability to develop on a timely basis
technologically advanced products that meet the appropriate industry
standards. Although New Ametek believes it has certain technological and other
advantages over its competitors, maintaining such advantages will require
continued investment by New Ametek in research and development and sales and
marketing. There can be no assurance that New Ametek will have sufficient
resources to make such investments or that New Ametek will be able to make the
technological advances necessary to maintain such competitive advantages. New
Ametek is not currently aware of any emerging standards or new products which
could render its existing products obsolete, although there can be no
assurance that this will not occur or that New Ametek will be able to develop
and market successfully new products.
 
  Proposed Tax Legislation. On April 17, 1997, Senate Finance Committee
Chairman William V. Roth Jr., Senate Finance Committee ranking Democrat Daniel
Patrick Moynihan and House Ways and Means Committee Chairman Bill Archer
introduced legislation (the "Proposed Legislation") that if applicable to the
Spin-Off and the Merger would cause the Spin-Off to be taxable to New Ametek.
The Proposed Legislation would not apply to any distribution after April 16,
1997 if the distribution is (i) made pursuant to a written agreement which was
(subject to customary conditions) binding on April 16, 1997 and at all times
thereafter, (ii) described in a ruling request submitted to the IRS on or
before April 16, 1997, or (iii) described on or before such date in a public
announcement or in a filing with the Commission required solely by reason of
the distribution (the "Transitional Relief"). Since the Spin-Off and the
Merger would satisfy one or more of the requirements for Transitional Relief,
the Proposed Legislation, if enacted in its present form, would not be
applicable to the transactions. However, there can be no assurance that the
Proposed Legislation would be enacted in its present form or that other
legislation, materially adverse to the Contributions, the Spin-Off or the
Merger and with different effective dates and/or transitional relief, would
not be introduced or enacted after the date hereof. The introduction or
enactment of legislation differing from the Proposed Legislation could delay
or prevent consummation of the Contributions, the Spin-Off and the Merger.
 
  THE FOLLOWING RISKS DO NOT CURRENTLY APPLY TO AMETEK BUT WILL APPLY TO NEW
AMETEK:
   
  Absence of Trading Market. There is currently no existing trading market for
New Ametek Common Stock but New Ametek has applied for listing of New Ametek
Common Stock on the NYSE and the PCX. AMETEK Common Stock has actively traded
on the NYSE and the PCX. While it is expected that a similar market will
develop for New Ametek Common Stock, there can be no assurance that trading
will be sustained or that the volume would be sufficient for trading to occur
with any frequency. As a result, it could be difficult to make purchases or
sales of New Ametek Common Stock in the market at any particular time. There
can be no assurance as to the price at which New Ametek Common Stock will
trade.     
 
  Certain Anti-Takeover Provisions. Certain provisions of the New Ametek
Certificate of Incorporation (the "New Ametek Certificate") and New Ametek By-
Laws, as well as Section 203 of the Delaware General Corporation Law ("DGCL")
and certain other provisions of Delaware corporate law, may have the effect of
making more difficult an acquisition of control of New Ametek in a transaction
not approved by New Ametek's Board. These provisions will allow New Ametek's
Board to issue, without stockholder approval, preferred stock having rights
senior to those of the New Ametek Common Stock, and impose various procedural
requirements that could make it more difficult for stockholders to effect
certain corporate actions, such as requiring a supermajority stockholder vote
to amend the New Ametek By-Laws and certain provisions of the New Ametek
Certificate, and denying the right of stockholders to take action by written
consent. In addition, the New Ametek Board is divided into three classes, each
of which serves a staggered three-year term. See "DESCRIPTION OF NEW AMETEK
CAPITAL STOCK--Description of Certain Statutory, Charter and By-Law
Provisions."

             AMETEK SELECTED HISTORICAL FINANCIAL INFORMATION     
   
  The following table sets forth selected historical consolidated financial
information for AMETEK for each of the years in the five-year period ended
December 31, 1996 and for the three month periods ended March 31, 1997 and
1996. The selected historical financial information for each of the five years
in the period ended December 31, 1996 has been derived from AMETEK's audited
consolidated financial statements. The table should be read in conjuction with
AMETEK's audited consolidated financial statements (including the notes
thereto) and financial information contained in the AMETEK 10-K. The selected
historical consolidated financial information as of and for each of the three
month periods ended March 31, 1997 and 1996 was derived from unaudited
financial statements of AMETEK, and should be read in conjunction with
AMETEK's quarterly report on Form 10-Q for the quarter ended March 31, 1997.
In the opinion of AMETEK's management, the selected consolidated financial
information as of and for the three months ended March 31, 1997 and 1996
include all adjustments (which consist of normal recurring accruals) necessary
to present fairly the information set forth therein. Results of operations for
the interim periods may not be indicative of results for the full year. See

</TABLE>    
- --------
   
(a) Amounts in 1993 include pre-tax charges totaling $54.9 million ($33.5
    million after tax, or $.77 per share) for restructuring and other unusual
    items.     
   
(b) Special items in 1995 include a $10.4 million ($.31 per share) gain from
    the sale of a discontinued operation and a $2.7 million ($.08 per share)
    after-tax loss related to debt agreements. Amounts in 1994 include an
    $11.8 million ($.32 per share) after-tax loss on the early extinguishments
    of debt and an after-tax gain of $3.8 million ($.11 per share) from the
    effect of a change in accounting for certain marketable securities.     
   
(c) EBITDA represents income from continuing operations before interest,
    taxes, depreciation and amortization, amortization of deferred financing
    costs, and nonrecurring items. It should not be considered, however, an
    alternative to operating income as an indicator of AMETEK's operating
    performance, or as an alternative to cash flows as a measure of AMETEK's
    overall liquidity as presented in AMETEK's financial statements. The
    EBITDA measure presented may not be comparable to other similar titled
    measures presented by other companies.     
   
(d) For purposes of calculating the ratio of earnings to fixed charges,
    earnings represents income from continuing operations before income taxes
    and fixed charges. Fixed charges consist of interest expense, amortization
    of deferred financing costs and the estimated component of operating lease
    expenses representing interest (assumed to be one-third). Earnings from
    continuing operations in 1993 were insufficient to cover fixed charges by
    approximately $13.5 million.

           NEW AMETEK UNAUDITED PRO FORMA FINANCIAL INFORMATION     
   
  The unaudited pro forma condensed consolidated statement of income of New
Ametek for the three months ended March 31, 1997, and for the year ended
December 31, 1996, and the unaudited pro forma condensed consolidated balance
sheet as of March 31, 1997 are derived by eliminating the Water Filtration
Business from the historical cost financial statements of AMETEK and are
presented as if the Spin-Off and the Merger had occurred on January 1, 1996
for the pro forma statement of income and on March 31, 1997 for the pro forma
balance sheet. In connection with the Spin-Off and the Merger, AMETEK will
transfer to New Ametek all of AMETEK's assets and liabilities, except for
those assets and certain liabilities relating to the Water Filtration Business
and certain indebtedness of AMETEK, and all of the outstanding shares of New
Ametek Common Stock will be distributed on a share for share basis to the
holders of AMETEK Common Stock.     
   
  The unaudited pro forma condensed consolidated financial information should
be read in conjunction with "Management's Discussion and Analysis of Financial
Condition and Results of Operations" in this Information Statement and is
presented for illustrative purposes only and is not necessarily indicative of
either (i) the financial condition or operating results that would have
occurred for the three months ended on March 31, 1997 or for the year ended
December 31, 1996 in the case of the pro forma condensed consolidated
statement of income, or on March 31, 1997, in the case of the pro forma
condensed consolidated balance sheet, or (ii) New Ametek's future operating
results or financial position. The pro forma adjustments described in the
accompanying notes to the Unaudited Pro Forma Condensed Consolidated Financial
Statements are based upon estimates and assumptions that management believes
are reasonable.

    NOTES TO AMETEK HISTORICAL AND NEW AMETEK UNAUDITED PRO FORMA CONDENSED
                    CONSOLIDATED FINANCIAL STATEMENTS     
          
(a) The elimination of the Water Filtration Business is based on the
    assumption that the Spin-Off and the Merger, which are subject to AMETEK
    stockholder approval, took place as of January 1, 1996 for the pro forma
    income statement, and as of March 31, 1997 for the pro forma balance
    sheet. The statement of income and the balance sheet of the Water
    Filtration Business were derived from AMETEK's historical cost financial
    accounts and includes certain allocations based upon methods considered
    reasonable by AMETEK's management. The financial statements of the Water
    Filtration Business referred to above were prepared in contemplation of
    the Merger.     
   
(b) To eliminate certain costs and expenses of AMETEK which were associated
    with the removal of the Water Filtration Business, and to reclassify
    certain commissions from other income to cost of sales.     
   
(c) To reflect the elimination of interest expense on debt of $25 million
    assumed to be transferred to Culligan in connection with the Spin-Off and
    the Merger.     
   
(d) To record estimated income taxes on the pro forma adjustments at statutory
    rates.     
   
(e) To record the settlement of intra-company loans and fees due AMETEK by the
    Water Filtration Business.     
   
(f) To reflect estimated fees and other expenses New Ametek expects to incur
    in 1997 in connection with the divestiture of the Water Filtration
    Business, and recognize the related income tax benefit on such fees and
    expenses. Such fees and expenses have not been reflected in the pro forma
    condensed consolidated statement of income because they are non-recurring.
           
(g) To reflect the assumed transfer of $25 million of debt from AMETEK to
    Culligan in connection with the Spin-Off.     
   
(h) To retire the issued treasury shares of AMETEK in accordance with the
    provisions of the Merger Agreement.

                   MANAGEMENT'S DISCUSSION AND ANALYSIS     
                
             OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS     
   
  Management's discussion and analysis of AMETEK's financial condition and
results of operations as set forth in the AMETEK 10-K for the year ended
December 31, 1996 and in its Quarterly Report on Form 10-Q for the quarter
ended March 31, 1997 are incorporated by reference herein. See "AVAILABLE
INFORMATION" and "INCORPORATION OF CERTAIN INFORMATION BY REFERENCE."
Management's discussion and analysis, set forth below, of AMETEK's unaudited
pro forma condensed consolidated statements of income and balance sheet should
be read in conjunction with AMETEK's selected historical financial information
and unaudited pro forma financial statements, referred to above, and the
related notes thereto, included elsewhere herein. The financial information
has been adjusted to present the pro forma elimination of the Water Filtration
Business (a wholly owned business of AMETEK, Inc.) and other pro forma
adjustments that principally reflect the transfer of debt in connection with
the elimination of that business assuming the Spin-Off and the Merger had been
completed as of the dates indicated.     
          
GENERAL     
   
  The Spin-Off will result in the distribution of New Ametek Common Stock to
the stockholders of AMETEK on a share for share basis. New Ametek will own all
of AMETEK's assets, except those relating to the Water Filtration Business of
AMETEK, and will have assumed all of AMETEK's liabilities, except for certain
liabilities relating to the Water Filtration Business and $25 million of
AMETEK's indebtedness, which will be transferred to Culligan in connection
with the Merger. The Merger will result in AMETEK (which then will be
comprised solely of the Water Filtration Business) becoming a wholly owned
subsidiary of Culligan and each issued and outstanding share of AMETEK Common
Stock will be converted into the right to receive approximately .11 shares of
Culligan Common Stock (based on 32,903,451 shares of AMETEK Common Stock
outstanding on June 13, 1997). Following consummation of the Spin-Off and the
Merger, New Ametek intends to reorganize its businesses into two groups: the
Electromechanical Group and the Electronic Instruments Group, to better
reflect New Ametek's principal emphasis on electronic and electromechanical
related businesses.     
   
RESULTS OF OPERATIONS     
   
 First Quarter Ended March 31, 1997     
   
  As a result of the pro forma elimination of the Water Filtration Business in
conjunction with the Spin-Off, pro forma sales for the first quarter of 1997
were $202.5 million, a decrease of $18.7 million or 8.5% compared with first
quarter 1997 historical sales. Operating income for the first quarter of 1997
on a pro forma basis was $21.8 million, a decrease of $3.2 million or 12.9%
compared with the first quarter 1997 historical results. Pro forma income from
continuing operations for the first quarter of 1997 was $11.8 million, a
decrease of $1.9 million or 14.0%, and pro forma earnings per share for the
same period were $0.36, a decrease of $0.06 or 14.3% compared with the first
quarter historical per share earnings. These decreases principally reflect the
pro forma elimination of the operating results of the Water Filtration
Business described above, partially offset by the pro forma reduction of
interest expense related to the debt to be transferred.     
          
 Year Ended December 31, 1996     
   
  As a result of the pro forma elimination of the Water Filtration Business in
conjunction with the Spin-Off, assumed to have taken place on January 1, 1996,
pro forma sales for 1996 were $800.0 million, a decrease of $68.7 million, or
7.9%, compared with 1996 historical sales. Operating income for 1996 on a pro
forma basis was $82.8 million, a decrease of $12.2 million, or 12.9%, compared
with 1996 historical results. Pro forma income from continuing operations for
1996 was $44.1 million, a decrease of $7.1 million or 13.8%, and pro forma
earnings per share for the same period was $1.35, a decrease of $0.22 or
14.0%, compared with 1996 historical per share earnings. These decreases
principally reflect the pro forma elimination of the operating results of the
Water Filtration Business as described above, partially offset by the pro
forma reduction of interest expense related to the transferred debt.     
 
                                      17

LIQUIDITY AND CAPITAL RESOURCES     
   
  Working capital at March 31, 1997 amounted to $82.0 million, on a pro forma
basis, an increase of $7.3 million compared to historical working capital of
$74.7 million at March 31, 1997. The increase in working capital is principally
due to the assumed transfer of $25 million of short-term debt to Culligan in
connection with the Merger, partially offset by the pro forma accrual of fees
and expenses related to the divestiture of $6.2 million and the pro forma
elimination of the Water Filtration Business, which has working capital of
$12.3 million.     
   
  The historical capital expenditures for the three months ended March 31, 1997
and for the year ended December 31, 1996, were $7.3 million and $41.2 million,
respectively, and include capital expenditures relating to the Water Filtration
Business of $0.7 million and $2.2 million for the three months ended March 31,
1997 and the year ended December 31, 1996, respectively.     
   
  On May 30, 1997, AMETEK received the necessary consents from holders of a
majority of its outstanding $150 million 9 3/4% Senior Notes due 2004 (the
"Notes") to amend the terms of the Indenture, dated as of March 15, 1994, as
amended and supplemented, between AMETEK and CoreStates Bank, N.A., as trustee
(the "Indenture"). The amendment was obtained to clarify that the Merger would
not conflict with the original terms of the Indenture.     
   
  AMETEK believes that, on the pro forma basis described above, it will have
sufficient cash-generating capabilities and available domestic and foreign
credit facilities to enable it to meet its needs in the foreseeable future.

                             THE CREDIT AGREEMENT
 
  In August 1995, AMETEK entered into a $195,000,000 revolving credit
agreement (the "Credit Agreement") with a group of banks (the "Bank Group"),
led by The Chase Manhattan Bank, N.A., as administrative agent ("Chase"). The
Credit Agreement replaced a $250,000,000 secured term and revolving loan
facility which AMETEK had entered into with the Bank Group in March 1994 (the
"Prior Facility"). In comparison to the Prior Facility, the Credit Agreement
is unsecured and has a more favorable interest rate structure and a somewhat
less restrictive set of covenants. In September 1996, AMETEK and the Bank
Group amended the Credit Agreement to (i) extend its maturity date to August
2, 2001, (ii) further improve the interest rate structure and (iii) ease
restrictions imposed by certain of its covenants.
 
  In connection with the Spin-Off, the Bank Group has entered into another
amendment to the Credit Agreement (the "Amendment") which, among other things,
permits the Credit Agreement to be assigned to and assumed by New Ametek. This
assignment and assumption shall occur immediately prior to the completion of
the Spin-Off. The Amendment also contemplates that, prior to the Spin-Off,
$25,000,000 of the outstanding principal under the Credit Agreement will be
replaced by separate loans from one or more members of the Bank Group and that
such separate loans will after the Spin-Off be retained by AMETEK as the
Retained Debt (the "Retained Debt"). The Amendment also provides some
additional relief under certain of the covenants contained in the Credit
Agreement, extends the maturity date to the fifth anniversary of the Spin-Off
Date and eliminates scheduled reductions in commitment levels.
 
  As so amended, the Credit Agreement will continue to place certain
restrictions on cash payments by New Ametek, including the payment of cash
dividends, together with other affirmative and negative covenants, including
restrictions on loans and incurrence of indebtedness and transactions with
affiliates.
   
  Outstanding loans under the Credit Agreement are subject to interest rate
swap and cap agreements based on the combination of a fixed rate and the
London Interbank Offered Rate ("LIBOR"), plus a negotiated spread over LIBOR.
At June 13, 1997, AMETEK had $48,400,000 in revolving credit loans outstanding
under the Credit Agreement at a blended interest rate of 6.40%.

                      THE CONTRIBUTIONS AND THE SPIN-OFF
 
  This section of the Information Statement describes certain aspects of the
Contributions and the Spin-Off. To the extent that they relate to the
Distribution Agreement, the Tax Allocation Agreement, the Transition Services
Agreement, the Indemnification Agreement or the Trademark Agreement
(collectively, the "Distribution Documents"), the following descriptions do
not purport to be complete and are qualified in their entirety by reference to
the respective agreements, which are attached as Appendix B and Appendix D to
the Joint Proxy Statement/Prospectus and are incorporated herein by reference.
STOCKHOLDERS SHOULD READ THE DISTRIBUTION AGREEMENT, THE TAX ALLOCATION
AGREEMENT, THE TRANSITION SERVICES AGREEMENT, THE INDEMNIFICATION AGREEMENT
AND THE TRADEMARK AGREEMENT IN THEIR ENTIRETY.
 
BACKGROUND OF AND REASONS FOR THE SPIN-OFF
   
  Because the Water Filtration Business is the only business of AMETEK that
Culligan wishes to acquire, AMETEK and Culligan determined to effect the Spin-
Off, which is intended to be tax-free to AMETEK and the holders of AMETEK
Common Stock for Federal income tax purposes (except to the extent of cash
received for fractional shares). See "CERTAIN FEDERAL INCOME TAX
CONSEQUENCES." It is a condition to consummating the Contributions, the Spin-
Off and the Merger that the Private Letter Ruling (which was issued) not be
revoked and/or that AMETEK and Culligan receive the Tax Opinions. The
Contributions followed by the Spin-Off will separate all of AMETEK's other
businesses from the Water Filtration Business and enable Culligan to acquire
only the Water Filtration Business in the Merger; the Spin-Off will leave
AMETEK's remaining businesses as a separate publicly held company (New
Ametek), owned by the existing holders of AMETEK Common Stock.     
 
  Although the Spin-Off will not be effected unless AMETEK's stockholders
approve the Spin-Off and the Merger and all other conditions precedent have
been satisfied or waived, the Spin-Off is separate from the Merger, and the
shares of New Ametek Common Stock to be received by holders of AMETEK Common
Stock in the Spin-Off do not constitute a part of the Merger consideration.
 
TERMS OF THE DISTRIBUTION AGREEMENT
 
 The Contributions
 
  Contributions of Assets
 
  Prior to the Spin-Off, pursuant to the Amended and Restated Contribution and
Distribution Agreement, dated as of February 5, 1997 (the "Distribution
Agreement"), between AMETEK and New Ametek, AMETEK will effect the
Contributions, with the result that New Ametek will own, directly or through
subsidiaries, all of the assets formerly owned by AMETEK or its subsidiaries,
other than the Water Filtration Business.
 
  Transfer of Liabilities
   
  At or prior to the time of the Spin-Off, New Ametek will assume all of the
liabilities of AMETEK, other than certain liabilities relating to the Water
Filtration Business and the Retained Debt (collectively, the "Assumed
Liabilities"). The Assumed Liabilities shall include AMETEK's outstanding
Notes and all obligations arising under the Credit Agreement, subject to the
retention by AMETEK of the Retained Debt. New Ametek shall also assume
liability for (i) uninsured health, dental and vision benefits incurred by
Water Filtration Business Employees prior to the Spin-Off but only if claims
therefor have been submitted prior to the Spin-Off, (ii) those benefits
incurred by Water Filtration Business Employees prior to the Spin-Off which
are covered by insurance policies assigned to and assumed by New Ametek, (iii)
all liability relating to or arising out of the defined benefit pension plans
maintained by AMETEK, other than the Water Filtration Business Hourly Pension
Plan, and (iv) all liability relating to or arising out of the 401(k) Plan
maintained by AMETEK.     
 
  AMETEK will retain certain liabilities relating to the Water Filtration
Business and the Retained Debt (the "Retained Liabilities").
 
                                      20
<PAGE>
 
  Certain Further Contributions
 
  If, after the time of the Spin-Off, either New Ametek or AMETEK holds assets
which by the terms of the Distribution Agreement or the Merger Agreement were
intended to be assigned and transferred to, or retained by, the other party,
such party will promptly assign and transfer or cause to be assigned and
transferred such assets to the other party.
 
 The Spin-Off
 
  Upon completion of the Contributions, the Spin-Off will be effected by the
distribution to each holder of record of AMETEK Common Stock as of the close
of business on the Spin-Off Record Date of certificates representing one share
of New Ametek Common Stock for every share of AMETEK Common Stock held by such
holder. As a result of the Spin-Off, the stockholders of record of AMETEK at
the close of business on the Spin-Off Record Date will own all of the
outstanding New Ametek Common Stock.
 
 Certain Covenants
 
  For five years after the Spin-Off, New Ametek will not, directly or
indirectly, (i) sell any products or render any services which are currently
being manufactured, sold or rendered by the Water Filtration Business, or (ii)
solicit any customer or supplier of the Water Filtration Business for any
purpose competitive with the Water Filtration Business; and for two years
after the Spin-Off, neither AMETEK nor New Ametek will, directly or
indirectly, solicit the employment of any employee of the other party and its
subsidiaries.
 
  Prior to the Spin-Off, AMETEK will transfer and assign to New Ametek all of
AMETEK's insurance policies other than (i) any policy which relates solely to
the Water Filtration Business and (ii) any policy that is not assignable
pursuant to its terms (a "Non-Assignable Policy"). If any policy is a Non-
Assignable Policy, it is the intent of AMETEK and New Ametek that New Ametek
receive the benefit of any coverage under any such policy, and that AMETEK
will keep such policy in effect during its remaining term and will refrain
from taking any actions (other than making a claim) which may affect New
Ametek's entitlement to the benefits of, or coverage under, such policy.
AMETEK and New Ametek also agree to cooperate with each other with respect to
the processing of any claims which are covered by any insurance policy in
existence prior to the Spin-Off.
 
 Settlement of Intercompany Balances
 
  All amounts owing between the New Ametek entities and the Water Filtration
Business entities, other than amounts arising in the ordinary course of
business, will be deemed paid in full at or prior to the Spin-Off.
 
 Employees and Employee Benefit Plans
 
  Effective as of the Spin-Off Date, New Ametek will offer employment to all
employees of AMETEK, other than employees of the Water Filtration Business, on
the same terms and conditions as were in effect immediately prior to the Spin-
Off. Any such transfer of employment from AMETEK to New Ametek will not
constitute a termination or qualifying event under any severance policy.
 
  Also effective as of the Spin-Off Date, New Ametek will adopt (i) the AMETEK
company-wide 401(k) Plan, (ii) the AMETEK company-wide Employees' Retirement
Plan, a defined benefit pension plan covering all salaried employees hired
before January 1, 1997; (iii) all hourly defined benefit pension plans
sponsored by AMETEK, other than the separate pension plan covering only hourly
employees of the Water Filtration Business; and (iv) all severance, vacation,
medical, disability, life insurance, split-dollar and other welfare benefit
plans covering employees (and their spouses and dependents) of AMETEK, other
than any such plans or arrangements covering only employees of the Water
Filtration Business or the separable portion of such plans or arrangements
attributable to employees of the Water Filtration Business. As soon as
practicable on or after the Merger, New Ametek shall cause the AMETEK 401(k)
Plan to make a direct plan-to-plan transfer to Culligan's 401(k) Plan
consisting of the account balances of those participants who are employed in
the Water Filtration Business. The Employee's Retirement Plan, as adopted by
New Ametek, will retain the liability for all accrued pension benefits,
including the accrued benefits of participants employed in the Water
Filtration Business, as determined at the
 
                                      21
<PAGE>
 
time of the Spin-Off, which benefits will be payable upon the participants'
subsequent retirement or termination of employment from Culligan, or death or
disability, as the case may be, as and to the extent provided for by the
Employees' Retirement Plan; provided, that any such participant employed in
the Water Filtration Business will continue to be credited under the
Employees' Retirement Plan for employment with AMETEK and Culligan after the
Spin-Off for purposes of vesting and eligibility for early retirement,
disability or pre-retirement death benefits (but not for the purpose of
determining the amount of the accrued benefit), and, further provided, that
any such participant's compensation shall continue to be recomputed by taking
into account compensation earned with AMETEK and Culligan after the Spin-Off
(but limited for Employees' Retirement Plan purposes to an increase of 5%, per
annum, of the 1996 compensation).
 
  Effective as of the Spin-Off Date, AMETEK shall continue to offer employment
to employees of the Water Filtration Business on the same terms and conditions
as in effect immediately prior thereto, and shall retain sponsorship of the
separate pension plan which covers only hourly employees of the Water
Filtration Business, and of all severance, vacation, medical, disability, life
insurance, split-dollar and other welfare benefit plans covering only
employees (and their spouses and dependents) of employees of the Water
Filtration Business or the separable portion of such plans or arrangements
attributable to employees of the Water Filtration Business.
 
  Stock Option and Stock Incentive Plans
   
  Prior to the Spin-Off, New Ametek will adopt one or more stock option, stock
incentive or similar plans for its employees and directors. New Ametek adopted
the 1997 Stock Incentive Plan of Ametek Aerospace Products, Inc. (the "1997
Plan") on June   , 1997 to be effective upon the Spin-Off Date. See
"MANAGEMENT--1997 Plan." Effective as of the Spin-Off Date, all outstanding
options to purchase AMETEK Common Stock which are held by employees, other
than the employees of the Water Filtration Business, whether or not such
options are currently exercisable, will be assumed by New Ametek and shall be
exercisable upon the same terms and conditions as in effect immediately prior
thereto; provided, however, that each such option shall cease to be
exercisable with respect to the AMETEK Common Stock and shall become
exercisable for a whole number of shares of New Ametek Common Stock and with
an adjusted per share exercise price, determined in accordance with Treasury
Regulation (S)1.425-1 (whether the option is an incentive stock option on a
nonqualified stock option) so as to preserve both the aggregate market spread
between the value of the shares of common stock subject to the option and the
exercise price of the option immediately before the Spin-Off, and the per
share ratio between the value of the common stock and the exercise price
immediately before the Spin-Off. All stock appreciation rights granted with
respect to AMETEK Common Stock held by employees, other than employees of the
Water Filtration Business, whether then exercisable, shall similarly be
assumed by New Ametek and shall be exercisable upon the same terms and
conditions as in effect immediately prior thereto, provided that the stock
appreciation rights shall be subject to adjustment in a manner similar to the
adjustments to the assumed stock options, as described in the preceding
sentence.     
 
  AMETEK has amended those outstanding stock options which are held by
employees of the Water Filtration Business to provide that, for a period
beginning March 20, 1997 and ending three business days prior to the Spin-Off
Date (the "Special Offer Period"), (i) such options are fully exercisable
(i.e., vested), (ii) each such option holder may, as an alternative to
exercise, surrender his or her options, in whole or in part, and receive from
AMETEK a cash amount equal to the market spread between the aggregate average
company share price (determined as the average closing prices of AMETEK Common
Stock for the ten trading days ending on the second trading day immediately
prior to the Effective Time) over the aggregate exercise price, in lieu of
exercising the underlying options and (iii) AMETEK will pay any holder of an
option which was granted as an incentive stock option (within the meaning of
Section 422 of the Code) who exercises or surrenders his options for the cash
spread during the Special Offer Period an amount, in cash, equal to 20% of the
taxable gain recognized from the exercise or surrender. For any option holder
who is employed by the Water Filtration Business and does not exercise or
surrender his options for cash during the Special Offer Period, any such
unexercised options shall, at the end of the Special Offer Period, revert to
the level of exercisability (i.e., vesting) as is determined solely by the
terms of the option and the length of the option holder's service since the
date of grant, and the right to surrender the options for cash and the right
of holders of options which were granted as incentive stock options to receive
the special 20% cash payment, as described above, shall lapse, and as of the
 
                                      22
<PAGE>
 
Effective Time, such unexercised options will be exchanged for options to
purchase Culligan Common Stock, all as described under "THE SPIN-OFF--Terms of
the Distribution Agreement--Stock Option and Stock Incentive Plans" in the
Joint Proxy Statement/Prospectus. Effective as of the Spin-Off Date, AMETEK
shall retain (and shall not contribute to New Ametek) cash in an amount equal
to 60% of the market spread of the unexercised options held by employees of
the Water Filtration Business.
 
  Conditions to the Spin-Off
 
  The obligations of AMETEK and New Ametek to consummate the Spin-Off and to
perform all other obligations set forth in the Distribution Agreement are
subject to the satisfaction or waiver of (i) all the conditions contained in
the Merger Agreement which relate to AMETEK or New Ametek, and (ii) the
condition that all authorizations, orders or approvals, or declarations or
filings with, or the expiration of waiting periods imposed by, any
governmental entity or other public or private entity the failure of which to
obtain would have a material adverse effect on AMETEK or New Ametek, will have
been filed, occurred, or been obtained.
 
  The obligations of AMETEK to consummate the Spin-Off and perform all other
obligations set forth in the Distribution Agreement are subject to the
satisfaction or waiver of the condition that New Ametek will have effected its
assumption of the Assumed Liabilities as contemplated by the Distribution
Agreement.
 
  The obligations of New Ametek to consummate the transactions contemplated by
the Distribution Agreement and to perform all other obligations set forth in
the Distribution Agreement are subject to the satisfaction or waiver of the
condition that AMETEK will have contributed to New Ametek the Contributed
Assets, as contemplated by the Distribution Agreement.
 
  Amendment
 
  The Distribution Agreement (including the Annexes, Schedules and exhibits
thereto) may be amended in writing by AMETEK or New Ametek at any time prior
to the Spin-Off with the prior written consent of Culligan. At any time prior
to the Spin-Off, either AMETEK or New Ametek may waive in writing compliance
by the other with any of the agreements or conditions contained in the
Distribution Agreement with the prior consent of Culligan. The failure of any
party to the Distribution Agreement to assert any of its rights under or to
enforce any provision of the Distribution Agreement or otherwise will not
constitute a waiver of its rights under such provision or any other provision.
 
TERMS OF THE TAX ALLOCATION AGREEMENT
 
  In connection with the Spin-Off and the Merger, AMETEK, New Ametek and
Culligan will enter into the Tax Allocation Agreement, which provides for the
allocation of all tax liabilities of AMETEK and its subsidiaries for taxable
periods before and after the Spin-Off. In general, under the Tax Allocation
Agreement, (i) New Ametek will be liable for any tax liability attributable to
the Water Filtration Business for taxable periods (or portions thereof) ending
on or before the Spin-Off Date and any tax liability attributable to the
assets and businesses to be transferred to or held by New Ametek (i.e., all of
the assets and businesses other than the Water Filtration Business) for all
taxable periods and (ii) AMETEK will be liable for any tax liability
attributable to the Water Filtration Business for taxable periods (or portions
thereof) beginning after the Spin-Off Date.
   
  In addition, except as provided below, New Ametek will be liable for any tax
liability resulting from transfers of stock and/or assets undertaken in
connection with or to effect the Contributions, the Spin-Off or the Merger
("Restructuring Taxes") including, without limitation, any tax liability
imposed on AMETEK as a result of the Contributions failing to qualify as a
reorganization under Section 368 (a) (1) (D) of the Code or the Spin-Off
failing to qualify as a distribution under Section 355 of the Code. AMETEK and
Culligan will be liable for any Restructuring Taxes caused by an action which
is inconsistent with Culligan's representations made in connection with
obtaining the Private Letter Ruling and/or the Tax Opinions and which is taken
by Culligan prior to the Spin-Off or by Culligan or AMETEK during the two-year
period after the Spin-Off. Furthermore, in     
 
                                      23
<PAGE>
 
the event that AMETEK and New Ametek would each be liable for taxes resulting
from the Spin-Off and/or the Merger (without regard for any action taken by
the other party), AMETEK and New Ametek shall each be liable for one-half of
such taxes and shall indemnify each other for any excess of such amount paid.
Pursuant to the Distribution Agreement, AMETEK and New Ametek shall share
equally all taxes (and certain other transaction costs) incurred in connection
with the Contributions and all transfer taxes imposed in connection with or as
a result of the Merger subject, in the case of AMETEK, to a limit of
$1,500,000.
 
TERMS OF THE TRANSITION SERVICES AGREEMENT
 
  In connection with the Spin-Off and the Merger, New Ametek and the Surviving
Corporation will enter into the Transition Services Agreement, which sets
forth the obligations of New Ametek to provide the Surviving Corporation with
certain transition services and support, including but not limited to, payroll
and benefits administration; administrative services related to employee
benefit plans; advertising and marketing services; fixed asset accounting;
vehicle fleet management; management information systems; treasury services;
risk management services; tax compliance information; access to a web site;
access to financial information for audited financial statements; access to
shared facilities; and such other services as may be requested from time to
time to assist in the transition, for a period of up to nine (9) months after
the date of the Transition Services Agreement. In consideration for such
transition services, the Surviving Corporation will pay to New Ametek a fee
based on New Ametek's fully burdened costs of providing such services, which
will be mutually agreed upon by New Ametek and the Surviving Corporation prior
to the time such transition services are provided.
 
TERMS OF THE INDEMNIFICATION AGREEMENT
 
  In connection with the Spin-Off and the Merger, AMETEK, New Ametek and
Culligan will enter into the Indemnification Agreement which sets forth each
party's rights and obligations with respect to indemnification for matters
relating to the Contributions, the Spin-Off and the Merger.
 
  The Indemnification Agreement will provide that except as otherwise
specifically provided in the Merger Agreement or any of the Distribution
Documents, New Ametek will indemnify, defend and hold harmless Culligan from
and against, and pay or reimburse Culligan for, all Indemnifiable Losses, as
incurred: (a) arising out of or resulting from (x) the Contributed Assets or
the Assumed Liabilities (including the failure by New Ametek or any subsidiary
or Affiliate of New Ametek to pay, perform or otherwise discharge such Assumed
Liabilities in accordance with their terms) whether such Indemnifiable Losses
arise out of or result from events, occurrences, actions, omissions, facts or
circumstances occurring, existing or asserted before, at or after the
Effective Time or (y) the conduct or operation of AMETEK's business (other
than the conduct and operation of the Water Filtration Business) prior to the
Effective Time; (b) arising out of or resulting from any untrue statement or
alleged untrue statement of a material fact contained in any of the
Registration Statements or in the Joint Proxy Statement/Prospectus, or any
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading; but only in each
case with respect to information provided by AMETEK relating to New Ametek or
AMETEK contained in or omitted from the Registration Statements or the Joint
Proxy Statement/Prospectus; (c) arising out of or resulting from the breach by
New Ametek or any of its subsidiaries of any agreement or covenant contained
in the Merger Agreement or any of the Distribution Documents which does not by
its express terms expire at the Effective Time or which is not by its express
terms required to be performed prior to the Effective Time; (d) arising out of
or resulting from any breach of or inaccuracy in any representation or
warranty of AMETEK or New Ametek contained in the Merger Agreement; (e)
arising out of or resulting from any actual or alleged violation of any law,

occurring or alleged to have occurred at or prior to the Effective Time with
respect to the New Ametek Businesses; (f) relating to or arising from any
claim that the execution, delivery or performance by AMETEK or New Ametek of
the Merger Agreement and each Ancillary Agreement to which it is or will be a
party or the consummation of the transactions contemplated
 
                                      24
<PAGE>
 
thereby results in a violation or breach of, or constitutes a default or
impermissible transfer under, or gives rise to any right of termination, first
refusal or consent under or gives rise to any right of amendment, cancellation
or acceleration of any material benefit under, any Contract to which AMETEK or
any of its subsidiaries is a party prior to the Spin-Off; and (g) arising out
of or relating to the handling, use, storage, recycling, treatment, transport,
Release or disposal of Hazardous Substances by AMETEK, any of its
subsidiaries, affiliates or predecessors (including any prior owner of the
Retained Realty (as defined below)) or any third party engaged by any of them,
prior to the Effective Time: (x) at any former properties or facilities of
AMETEK or any of its subsidiaries, affiliates, or predecessors (including any
prior owner of the Retained Realty, including former properties or facilities
relating to the Retained Assets or the Water Filtration Business (but not
including any real property owned or leased by the Water Filtration Business,
as of the Spin-Off Date (the "Retained Realty")); (y) at the Retained Realty,
but only to the extent that the Indemnifiable Losses arise from activities or
business operations that preceded the activities or business operations of the
Water Filtration Business at the Retained Realty; and (z) at any site or
location other than the Retained Realty where such handling, use, storage,
recycling, treatment, transport, Release or disposal (or arranging for such
activities by third parties) was related to the activities or business
operations of the Retained Assets or the Water Filtration Business (provided
that this clause (z) shall not cover any migration of a Release from the
Retained Realty).
 
  The Indemnification Agreement will further provide that except as otherwise
specifically provided in the Merger Agreement or any of the Distribution
Documents, Culligan will indemnify, defend and hold harmless, or cause AMETEK
to indemnify, defend and hold harmless New Ametek from and against, and pay or
reimburse New Ametek for, all Indemnifiable Losses, as incurred: (a) arising
out of or resulting from (x) the Water Filtration Business or the Retained
Liabilities (including the failure by Culligan or any of its subsidiaries to
pay, perform or otherwise discharge such Retained Liabilities in accordance
with their terms) whether such Indemnifiable Losses arise out of or result
from events, occurrences, actions, omissions, facts or circumstances
occurring, existing or asserted before, at or after the Effective Time or (y)
the conduct or operation of the Water Filtration Business following the
Effective Time (other than any such conduct or operation which would give rise
to a right to indemnification by the Parent Indemnitees under the
Indemnification Agreement); (b) arising out of or resulting from any untrue
statement or alleged untrue statement of a material fact contained in any of
the Registration Statements or in the Joint Proxy Statement/Prospectus, or any
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading; but only in each
case with respect to information provided by Culligan relating to Culligan or
any of its subsidiaries (other than AMETEK and its subsidiaries) contained in

to or arising from any claim that the execution, delivery or performance by
Culligan or Culligan Merger Sub of the Merger Agreement and each Ancillary
Agreement to which it is or will be a party or the consummation of the
transactions contemplated thereby results in a violation or breach of, or
constitutes a default or impermissible transfer under, or gives rise to any
right of termination, first refusal or consent under or gives rise to any
right of amendment, cancellation or acceleration of any material benefit
under, any Contract to which Culligan or Culligan Merger Sub is a party prior
to the Spin-Off.
 
  The Indemnification Agreement will provide that with respect to
Indemnifiable Losses arising out of or resulting from any breach or inaccuracy
in any representation or warranty of AMETEK or New Ametek contained in the
Merger Agreement, New Ametek will not have any liability under the
Indemnification Agreement unless the aggregate of all Indemnifiable Losses for
which New Ametek would be liable under the Indemnification Agreement exceeds
on a cumulative pre-tax basis an amount equal to $800,000 (the "Basket
Amount"); provided, that, once the Basket Amount is exceeded, New Ametek will
only pay Indemnifiable Losses in excess of such Basket Amount. Notwithstanding
the foregoing, New Ametek's liability for Indemnifiable Losses arising out of
or resulting from any breach or inaccuracy in any representation or warranty
of AMETEK or New Ametek contained in the Merger Agreement is limited (i) in
the aggregate to $25,000,000
 
                                      25
<PAGE>
 
and (ii) to only those Indemnifiable Losses for which New Ametek has received
written notice of on or prior to eighteen months from the Closing Date.
 
TERMS OF THE TRADEMARK AGREEMENT
 
   Following the time of the Spin-Off, New Ametek will have the sole and
exclusive ownership of and right to use all of the names, trademarks, trade
names and other proprietary rights of AMETEK (collectively, the "Intellectual
Property"), including all rights to the "Ametek" name other than the
intellectual property relating primarily to the Water Filtration Business.
Pursuant to the Trademark Agreement between AMETEK and New Ametek, AMETEK will
retain the right to use, for a period of five years, the "Ametek" trade name
and any AMETEK trademarks, service marks or logos which use the word "Ametek"
and are currently in use by the Water Filtration Business (collectively, the
"Marks"). In addition, for the three successive one year terms following such
five year period, New Ametek will grant to AMETEK, pursuant to the Trademark
Agreement, an exclusive worldwide license to the Marks at a royalty rate of
$1,000,000 per year. AMETEK (which following the Merger will have changed its
name to "Culligan Water Company, Inc.") is prohibited, however, from using the
"Ametek" mark alone or in combination with other terms, as part of a corporate
name. The Trademark Agreement also provides for usual and customary
provisions, including quality control, audit and marking provisions.

                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
  The following is a summary of certain Federal income tax consequences of the
Contributions, the Spin-Off and the Merger. This summary is based upon the
Code, Treasury regulations promulgated thereunder, and judicial and
administrative interpretations thereof, all as in effect on the date hereof,
and which are subject to changes occurring after such date, possibly with
retroactive effect. This summary is for general information only and does not
address the effects of any state, local or foreign tax laws. In addition, it
does not purport to address all of the tax consequences applicable to any
particular taxpayer or to taxpayers subject to special treatment under the
Code, including, without limitation, foreign holders, holders of AMETEK Common
Stock acquired pursuant to the exercise of employee stock options or otherwise
as compensation, insurance companies, tax-exempt organizations, financial
institutions, broker dealers or persons who do not hold the AMETEK Common
Stock as a capital asset. EACH HOLDER OF AMETEK COMMON STOCK IS URGED TO
CONSULT HIS OR HER TAX ADVISOR AS TO THE SPECIFIC TAX CONSEQUENCES TO HIM OR
HER OF THE SPIN-OFF AND THE MERGER, INCLUDING THE APPLICATION AND EFFECT OF
STATE, LOCAL AND FOREIGN INCOME AND OTHER TAX LAWS AND OF CHANGES IN
APPLICABLE TAX LAWS.
   
  The Private Letter Ruling was issued on June 16, 1997. The Contributions,
the Spin-Off and the Merger will not be consummated unless the IRS shall have
not revoked the Private Letter Ruling substantially to the effect that, on the
basis of the facts, representations and assumptions existing at the Effective
Time: (i) the Contributions followed by the Spin-Off qualify as a tax-free
reorganization pursuant to Section 368(a)(1)(D) of the Code; (ii) the Spin-Off
qualifies as a tax-free distribution pursuant to Section 355(a) of the Code;
and (iii) the Merger qualifies as a tax-free reorganization pursuant to
Section 368 (a)(1)(B) of the Code.     
   
  If the IRS revokes the Private Letter Ruling as to any one or more of the
three rulings described in the preceding paragraph (each, an "Omitted
Ruling"), this requirement will nevertheless be satisfied if, on or prior to
the Closing Date, AMETEK receives the Tax Opinion of Stroock & Stroock & Lavan
LLP and Culligan receives the Tax Opinion of Skadden, Arps, Slate, Meagher &
Flom LLP (together, the "Tax Opinions") to the same effect as each such
Omitted Ruling. Each such Tax Opinion, if any, would be based upon certain
qualifications and assumptions as noted therein and upon certain
representations of AMETEK, New Ametek and Culligan. It would represent such
counsel's best legal judgment and would not be binding on the IRS or the
courts. There can be no assurance that the IRS or the courts would not take
one or more contrary positions to those expressed in the Tax Opinions.     
   
  The Contributions, the Spin-Off and the Merger will also not be consummated
unless there shall be no proposed legislation introduced in bill form and
pending action in Congress which, if enacted into law, would have the effect
of amending the Code so as to alter in any materially adverse respect any of
the Federal income tax consequences described in the Private Letter Ruling
(and/or the Tax Opinions) in respect of the Contributions, the Spin-Off or the
Merger. On April 17, 1997, Senate Finance Committee Chairman William V. Roth
Jr., Senate Finance Committee ranking Democrat Daniel Patrick Moynihan and
House Ways and Means Committee Chairman Bill Archer introduced the Proposed
Legislation that if applicable to the Spin-Off would cause the Spin-Off to be
taxable to New Ametek. The Proposed Legislation would not apply to any
distribution after April 16, 1997 if the distribution is (i) made pursuant to
a written agreement which was (subject to customary conditions) binding on
April 16, 1997 and at all times thereafter, (ii) described in a ruling request
submitted to the IRS on or before April 16, 1997, or (iii) described on or
before such date in a public announcement or in a filing with the Commission
required solely by reason of the distribution. Since the Spin-Off and the
Merger would satisfy one or more of the requirements for Transitional Relief,
the Proposed Legislation, if enacted in its present form, would not be
applicable to the transactions. However, there can be no assurance that the
Proposed Legislation would be enacted in its present form or that other
legislation, materially adverse to the Contributions, the Spin-Off or the
Merger and with different effective dates and/or transitional relief, would
not be introduced or enacted after the date hereof. The introduction or
enactment of legislation differing from the Proposed Legislation could delay
or prevent consummation of the Contributions, the Spin-Off and the Merger.

CONSEQUENCES OF THE CONTRIBUTIONS AND THE SPIN-OFF
 
  Based upon the Private Letter Ruling (and/or the Tax Opinions), the
following is a summary of the anticipated Federal income tax consequences of
the Contributions and the Spin-Off:
 
    1. No gain or loss will be recognized by (and no amount will be included
  in the income of) holders of AMETEK Common Stock on their receipt of New
  Ametek Common Stock in the Spin-Off.
 
    2. Following the Spin-Off, the aggregate tax basis of the AMETEK Common
  Stock and the New Ametek Common Stock in the hands of the holders of AMETEK
  Common Stock will equal the tax basis of the AMETEK Common Stock held
  immediately before the Spin-Off, allocated in proportion to the fair market
  value of each on the Spin-Off Date.
 
    3. The holding period of the New Ametek Common Stock received by the
  holders of AMETEK Common Stock will include the holding period of the
  AMETEK Common Stock on which the Spin-Off was made, provided such AMETEK
  Common Stock is held as a capital asset on the Spin-Off Date.
 
    4. No gain or loss will be recognized by AMETEK or New Ametek as a result
  of the Contributions or the Spin-Off.
 
  If the Contributions and the Spin-Off did not qualify for tax-free treatment
under Code Sections 368(a)(1)(D) and 355, then for Federal income tax purposes
(i) AMETEK would be required to recognize gain on the Spin-Off to the extent
that the fair market value of the shares of New Ametek Common Stock
distributed in the Spin-Off exceeded AMETEK's tax basis of such shares and
(ii) each holder of AMETEK Common Stock would be required to recognize
dividend income in an amount equal to the fair market value of the shares of
New Ametek Common Stock received in the Spin-Off, up to such stockholder's
allocable share of AMETEK's current and accumulated earnings and profits
(which would include the amount of gain referred to in clause (i) above).
 
CONSEQUENCES OF THE MERGER
 
  Based upon the Private Letter Ruling (and/or the Tax Opinions), the
following is a summary of the anticipated Federal income tax consequences of
the Merger:
 
    1. No gain or loss will be recognized by holders of AMETEK Common Stock
  whose shares of AMETEK Common Stock are exchanged solely for Culligan
  Common Stock pursuant to the Merger Agreement (except with respect to cash
  received by such holders of AMETEK Common Stock in lieu of fractional
  shares of Culligan Stock). An AMETEK stockholder who receives cash in lieu
  of fractional shares of Culligan Common Stock will recognize capital gain
  or loss in an amount equal to the difference between the cash so received
  and the portion of the tax basis in AMETEK Common Stock (as determined
  immediately following the Spin-Off) that is allocable to such fractional
  share. Such capital gain or loss will be long-term capital gain or loss,
  provided such fractional shares would have been held by such stockholder as
  a capital asset immediately prior to the Merger.
 
    2. The tax basis of the Culligan Common Stock received (or, in the case
  of fractional shares, deemed received) by holders of AMETEK Common Stock
  who exchange their AMETEK Common Stock solely for Culligan Common Stock in
  the Merger will be the same as the aggregate tax basis of the AMETEK Common
  Stock (as determined immediately following the Spin-Off) surrendered in
  exchange therefor.
 
    3. The holding period for the shares of Culligan Common Stock received in
  the Merger will include the period during which the shares of the AMETEK
  Common Stock surrendered in exchange therefor were held, provided that such
  shares of AMETEK Common Stock were held as a capital asset immediately
  prior to the Merger.
 
    4. No gain or loss will be recognized by AMETEK, Culligan Merger Sub or
  Culligan as a result of the Merger.
 
  If the Merger did not qualify for tax-free treatment as a reorganization
under Code Section 368(a)(1)(B), each holder of AMETEK Common Stock would
recognize gain or loss equal to the difference between the fair market value
of the Culligan Common Stock received and such holder's tax basis of the
shares of AMETEK Common Stock surrendered. Failure of the Merger to qualify as
a tax-free reorganization could jeopardize the tax-free treatment of the
Contributions and the Spin-Off under Code Sections 355 and 368(a)(1)(D).

                LISTING AND TRADING OF NEW AMETEK COMMON STOCK
   
  New Ametek has applied for listing of the New Ametek Common Stock on the
NYSE and the PCX.     
 
  New Ametek Common Stock received pursuant to the Spin-Off will be freely
transferable under the Securities Act of 1933, as amended (the "Securities
Act"), except for shares of New Ametek Common Stock received by any person who
may be deemed an "affiliate" of New Ametek within the meaning of Rule 145
under the Securities Act. Persons who may be deemed to be affiliates of New
Ametek after the Spin-Off generally include individuals or entities that
control, are controlled by, or are under common control with New Ametek, and
may include the directors and principal executive officers of New Ametek as
well as any principal stockholder of New Ametek. Persons who are affiliates of
New Ametek may sell their shares of New Ametek Common Stock received pursuant
to the Spin-Off only pursuant to an effective registration statement under the
Securities Act covering such securities, or in compliance with the resale
provisions of Rule 144 or Rule 145 or Regulation S promulgated under the
Securities Act.
                                
                             DIVIDEND POLICY     
   
  AMETEK currently pays a quarterly cash dividend of $.06 per share. New
Ametek presently intends to continue paying a similar dividend. The payment of
dividends by New Ametek is dependent upon future earnings, financial
requirements, contractual provisions of debt agreements and other relevant
factors.     
 
                                      29
<PAGE>
 
                                   BUSINESS
 
  AMETEK, Inc. was incorporated in Delaware in 1930 under the name of American
Machine and Metals, Inc. and maintains its principal executive offices at
Station Square, Paoli, Pennsylvania 19301.
   
  New Ametek will be the successor to all of AMETEK's current businesses
except for the Water Filtration Business. Management believes AMETEK currently
is, and upon completion of the Spin-Off, New Ametek will continue to be, a
leading global manufacturer of electrical and electronic products and
materials engineered for niche markets with operations in North America,
Europe and Asia. It is expected that approximately one-third of New Ametek's
sales will be to international markets. New Ametek will have a significant
market share for many of its products. The Electromechanical Group is the
world's largest independent producer of electric motors and blowers for vacuum
cleaners and floor-care products; the Precision Instruments Group builds
technologically advanced monitoring, sensing, calibration, and display devices
for the aerospace, process, and heavy-vehicle industries; and the Industrial
Materials Group uses plastics, metals and fibers to produce specialty
materials for consumer and industrial markets. AMETEK has grown through a
focus on the manufacturing of electronic, electromechanical and electrical
products for niche markets where, based on technological or cost advantages,
it has or it seeks to build a significant market share. The management of New
Ametek intends to continue this focus.     
 
CONTINUATION OF STOCKHOLDER VALUE ENHANCEMENT PLAN
 
  In November 1993, AMETEK adopted a Stockholder Value Enhancement Plan (the
"Plan") with the objective of improving AMETEK's earnings growth through a
combination of financial and operating strategies.
   
  The Plan's financial strategies consist of an ongoing share repurchase
program, a debt refinancing (completed in 1994) and a dividend reduction
(adopted at the same time as the Plan). From inception of the Plan through
December 31, 1996, AMETEK has repurchased approximately 30% of its outstanding
shares. This represents approximately 12.2 million shares of common stock at
an aggregate repurchase price of $171 million (or an average cost of $14.01
per share). During 1996, AMETEK repurchased 698,000 shares at an aggregate
repurchase price of $12.5 million (or an average cost of $17.92 per share).
Also, during 1996, AMETEK's Board of Directors authorized the current share
repurchase program of up to $50 million. No share repurchases have been made
to date in 1997. New Ametek intends to continue the share repurchase program
under the same $50 million authorization.     
 
  Shortly after the Plan was adopted, AMETEK implemented certain of its
operating strategies by restructuring the Precision Instruments Group and, as
a result, incurring after-tax charges of $33.5 million in 1993. The Plan's
other operating strategies, which are ongoing, consist of: (i) achieving
operational excellence through improved asset management, increased operating
synergies and reduced cycle times, (ii) intensifying new product development
efforts, especially in the electric motor-blower, precision instruments and
specialty metal product lines, (iii) completing strategic acquisitions and
alliances which concentrate on improving AMETEK's technological and
manufacturing advantages and market position in its core businesses, and (iv)
pursuing global and market expansion, especially in Europe and Asia.
 
  In continuing to carry out the financial and operating strategies of the
Plan, AMETEK has sought, and New Ametek will continue to seek, to allocate its
historically strong cash flow to those opportunities, including the
furtherance of its operating strategies, additional share repurchases and
further debt reductions, which appear to have the best potential for improving
earnings growth and thereby, in accordance with the Plan, enhancing
stockholder value.
 
PRODUCTS AND SERVICES
   
  New Ametek's growth strategies will be focused on its principal businesses:
Electromechanical, Precision Instruments, and Industrial Materials.

 Electromechanical Group
 
  The Electromechanical Group is the world's largest independent producer of
high-speed, air-moving electric motors for original equipment manufacturers
("OEM's") of floor-care products. The manufacture of these motors with
contacts rotating at 25,000 to 40,000 RPM requires advanced manufacturing
technology. EMG must address complex motor-blower dynamics including heat,
noise, vibration, and wear, in designing its customized products. EMG's
worldwide franchise is based on competencies developed over 80 years. EMG has
a leading market share in North America and Western Europe and a growing share
in the Pacific Rim. Global sales have more than quadrupled since 1981--
increasing from approximately $80 million to $376 million in 1996.
 
  EMG has grown its business by extending its technological expertise in
manufacturing high-speed, air-moving electric motors for a variety of targeted
markets, with the floor care market being its primary focus. EMG has formed
alliances with OEM customers to design and manufacture cost-effective products
for numerous floor care applications. EMG is also using its technological and
marketing expertise in an effort to penetrate new markets, such as lawn and
garden equipment, where it is seeking to establish alliances with its major
customers.
 
  EMG is seeking to build on it market leadership in the floor-care markets of
North America and Europe, through initiatives in Eastern Europe, Latin America
and the Pacific Rim. In addition to pursuing strategic alliances and joint
ventures, EMG has expanded its presence in the Pacific Rim with a plant in
Shanghai, PRC. Operations in Shanghai, the Czech Republic and Mexico are
expected to contribute to manufacturing output in 1997. About 50% of EMG's
sales are outside of the United States.
 
  Consistent with its strategies for long-term global growth and low-cost
producer status, EMG has increased its production capacity over the past three
years with highly automated production lines at its Graham, North Carolina
facility. The recently initiated operations in Reynosa, Mexico; Shanghai, PRC;
and the Czech Republic are focused on reducing costs, and later on market
expansion.
   
  EMG employs approximately 3,000 people and has fourteen manufacturing
locations: six in the United States, three in Italy, three in Mexico, and one
each in the PRC and the Czech Republic. EMG produced approximately 22 million
motor products in 1996 with flexible, automated production lines designed for
low-cost, high-volume operations. Its technological resources provide EMG
customers with custom-designed products.     
 
  Floor-Care Market and Product Line
 
  About two-thirds of EMG's sales are to floor-care markets, where it has a
leading share through sales of air-moving electric motors to most of the
world's major floor-care OEMs, including integrated OEMs that produce some of
their own motors. EMG produces a full range of floor-care products, from hand-
held, canister and upright vacuums to central vacuums for residential use.
High-performance vacuums are marketed for commercial and industrial
applications. Customers include Matsushita, Bissell, Royal, Eureka, and SEB-
Rowenta.
 
  Sales growth in the floor-care industry has been achieved by marketing
products to vertically integrated vacuum cleaner manufacturers which decide to
outsource motor production to realize the economic and operational advantage
of reducing or discontinuing their own motor production. By purchasing EMG's
motors, vacuum cleaner manufacturers can reduce the otherwise substantial
capital expenditures they would incur to manufacture motors for changing
consumer demands. The global consumer trend toward multiple floor-care
products increases the variety and frequency of these investments by OEMs,
which are striving to operate more economically.
 
  EMG's new product development focuses on enhancing motor-blower cost-
performance through advances in power, efficiency, size, weight, and
quietness. EMG's world lamination motor design is gaining market share in the
world lawn and garden market due to the motor's superior performance-to-weight
ratio. A new line of high-efficiency fans complement this motor and are
targeted as one of EMG's major growth initiatives for floor-care applications
in Asia.
 
                                      31
<PAGE>
 
  EMG has a significant position in the European floor-care market. The
electric motors it produces in Italy are similar to those produced in the
United States. Capacity and productivity in Italy have been increased through
capital investment and such initiatives as manufacturing integration,
automation, inventory management, and increased labor flexibility.
 
  Technical Motor Market and Product Line
 
  EMG formed the Technical Motor Division to capitalize upon its global
presence and technical expertise in floor-care products and to expand
production and marketing of its brushless DC motor-blowers.
 
  EMG's brushless motors are used in computer equipment, business machines and
medical equipment. Brushless motors are free of static charges and have high
reliability. They are increasingly popular in medical and other applications
in which long life and speed control are desired. Continuing product
developments include the use of brushless motors in systems designed to assist
patients with sleep-breathing disorders, in hospital air-mattress systems as
well as systems that recover gasoline fumes at automotive fueling stations.
Customers include Thomas Industries, Gast, Rheem, Kinetic Concepts, and
DevilBiss.
 
  Commercial Motor Market and Product Line
 
  EMG's leadership in air-moving electric motors, and its manufacturing
infrastructure, technical expertise and global marketing strengths serve as
the foundation for its future growth. EMG is capitalizing on its core
competencies in air-moving electric motors to create opportunities in other
consumer products for the outdoor power equipment market, such as lawn and
garden equipment, chainsaws, low-pressure paint sprayers and high-pressure
power washers. For example, EMG has received orders from most of the world's
major producers of lawn and garden products. Customers include Poulan,
American Kleaner, Sunbeam, and Wagner Spray Tech.
 
  Customers
   
  EMG is not dependent on any single customer such that the loss of that
customer would have a material adverse effect on EMG's operations.
Approximately 27% of EMG's first quarter 1997 sales and 31% of its sales for
1996 were made to its five largest customers.     
 
 Precision Instruments Group
 
  The Precision Instruments Group applies its niche market focus and
technology to produce monitoring, calibration and display instruments for the
aerospace, process and heavy vehicle industries.
   
  PI's growth has and will be based on competitive advantages, which include
designing products for specific customer applications that are significantly
differentiated from or are lower in cost than competitive products. PI is
among the leaders in many of the niche markets it serves, including aerospace
fuel-flow meters, heavy vehicle instrument panels, oxygen analyzers, and
pressure gauges. About 25% of sales are to markets outside the United States.
    
  Process and Analytical Instruments Market and Product Line
   
  Approximately one-half of PI's 1996 sales are process and analytical
instruments, and pressure sensors. This includes pressure gauges and products
for industrial measurement and calibration; oxygen, moisture, combustion and
liquid analyzers; and emission monitors. The market focus is on measurement
and analysis for the process industry, which includes refining, and
petrochemical plants, power generation, specialty gas, water and waste
treatment, and natural gas distribution. PI also has products which serve the
semiconductor market. PI is one of the leaders in the North American pressure
gauge market, which has been adversely affected by low-cost offshore products.
PI has reduced costs through restructuring its Sellersville, PA operations and
through its joint venture in Taiwan and the PRC. It is also refocusing its
domestic manufacturing on more advanced pressure measurement products, such as
its new Electronic Pressure Calibrator Model 2000.     
 
                                      32
<PAGE>
 
  In connection with its global expansion, PI has 50% ownership of a joint
venture that manufactures low-cost pressure gauges in Taiwan and the PRC,
where the joint venture also markets these products. For the remainder of the
world, PI is the exclusive marketer of the joint venture's products, expanding
PI's leadership in price-sensitive gauges.
 
  The process industry has experienced lackluster market conditions in the
United States, primarily due to reduced refinery and petrochemical plant
construction and lower industry operating rates, resulting in part from
increased environmental regulations. Worldwide process industry markets are
benefiting from improved economic conditions and new construction in Europe
and Asia, where increased growth and market expansion are expected. PI's
customers include Exxon, DuPont, and Intel.
   
  In June 1997, AMETEK completed the acquisition of the Test & Measurement
Products division of Technitrol, Inc. With prior annual sales of approximately
$30 million, the acquired business manufactures a comprehensive line of force-
measurement and testing devices in the United States and Europe, including
hand-held gauges, electronic instruments, and test stands, and provides
analytical software and support services. Its products are marketed worldwide
predominantly under the Chatillon and Lloyd brand names through a global
network of distributors, sales representatives and direct sales.     
 
  Aerospace Market and Product Line
   
  Approximately one-third of PI's 1996 revenues are from the sale of aerospace
products, including airborne-data and vibration-monitoring systems; turbine
engine temperature measurement; indicators and displays, fuel and fluid
measurements; and sensors, switches and cable harnesses. Its customers are the
leading producers of airframes and jet engines, commercial airlines and
aircraft operators. As a prime innovator, PI serves all segments of commercial
aerospace, including helicopters, business jets, commuter aircraft, and
commercial airliners. Customer support includes parts warehousing and
maintenance programs. Aerospace products are designed to customer
specifications and manufactured to stringent operational and reliability
requirements. Operations are in Binghamton, NY; Sellersville, PA and
Wilmington, MA. A repair and maintenance facility is in Seattle, WA.     
 
  The aerospace business operates in niche markets, where its products have a
technological and/or cost advantage. Its 50 years of experience as an
aerospace contractor and its long-standing customer relationships with global
commercial aircraft OEMs are significant competitive advantages. Its new
products are now in service on the Boeing 777 airliner, the Bombardier Global
Express business jet and the Agusta 109 helicopter. Other aircraft with PI
products aboard include: Learjet 60, Boeing 737/747/757/767, Beechjet,
Sikorsky S-64, Cessna Citation, Saab SK-60, Mitsubishi YS-11 and Bell 407. Jet
engines with PI products include GE 90, Pratt & Whitney 4000 series, Rolls
Royce Trent 700/800 and GE CF6-50/80 series. Customers include Boeing, General
Electric, Honeywell and the U.S. Government.
 
  In 1993, PI reduced costs and restructured operations to increase
profitability in a weak aerospace market. Further initiatives are achieving
additional synergies, improving asset management, and optimizing the benefits
of prior actions. Demand in the aerospace market has strengthened
significantly, as airlines replace aging fleets, airline passenger miles
increase, and airline profits improve.
 
  Heavy Vehicle Market and Product Line
   
  Approximately one-fifth of PI's 1996 sales are electronic and
electromechanical instruments and panels for heavy vehicles, such as Class 8
heavy trucks. New products, acquisitions and the addition of construction and
agricultural vehicle markets have increased the markets served. The
acquisition of privately held Dixson, Inc. in 1995 added to PI's number one
position in the United States heavy truck market and increased market share in
other heavy vehicle instrument segments, including agricultural, construction
and off-road vehicles. Dixson, Inc. also has a complementary customer base, a
market position in Europe, and product development capabilities in solid-state
instruments that primarily monitor engine efficiency and emissions. Instrument
demand in 1996 was reduced by a down cycle in the heavy truck industry. Modest
industry improvement is expected in 1997. Customers include Peterbilt and
Kenworth, Mack, Volvo, Freightliner, Ford, Clark and Caterpillar.     
 
                                      33
<PAGE>
 
  Customers
   
  The Precision Instruments Group is not dependent on any single customer such
that the loss of that customer would have a material adverse effect on PI's
operations. Approximately 24% of PI's first quarter 1997 sales and 27% of its
1996 sales were made to its five largest customers.     
 
 Industrial Materials Group
   
  The Industrial Materials Group is a leader in the manufacture of specialized
or customized technology-based materials and products in many niche markets.
It uses proprietary mechanical, metallurgical and plastics technology to
develop differentiated products, including high-purity metal powders and
products, and materials for industrial and chemical processing.     
 
  Specialty Metals Markets and Product Line
 
  This business manufactures high-purity, engineered metal powders; high-
purity strip and wire from metal powders; and clad products, with specific
metallurgical properties. Its niche market focus is based upon proprietary
manufacturing technology and strong customer relations. IMG serves a diverse
market segment including consumer products, electronics, telecommunications,
automotive, and energy production. New product developments include patented
ultra stainless steel metal powders and copper-based spinodal(R) alloys.
Global and market expansion in Europe and Asia significantly increased sales
in 1996. Customers include DuPont, Regal Ware, Inc., Stoody Co., Smith
International and Pall Corp.
 
  Chemical and Industrial Products
 
  Products include silicas, phenolic resins, and Teflon(R) (a registered
trademark of DuPont) polymer products for high-temperature and highly
corrosive applications. Product applications include the filtering of molten
metal, heat exchangers and protective welding curtains. The Chemical Products
Division also is a custom compounder of specialty resins and thermoplastics
with enhanced properties, such as fire retardance and improved adhesion.
Markets include automotive parts, electronics, appliances, and
telecommunications markets. Customers include Exxon, Mytex, Kanetsu, DuPont,
and Newport News Shipbuilding.
 
  Customers
   
  IMG is not dependent on any single customer such that the loss of that
customer would have a material adverse effect on IMG's operations.
Approximately 21% of IMG's first quarter 1997 sales and 23% of its 1996 sales
were made to its five largest customers.     
 
MARKETING
 
  In general, AMETEK's marketing efforts are organized and carried out at the
group and divisional levels, and New Ametek expects that this will continue
after the Spin-Off. Given the similarity and technical nature of its many
products as well as its significant worldwide market share, EMG conducts most
of its domestic and international marketing activities through a direct sales
force, and makes only limited use of sales agents in other countries. Because
of their relatively diverse product lines, PI and IMG make significant use of
distributors and sales agents in marketing their products. With its
specialized customer base of aircraft and jet engine manufacturers, and
airlines, PI's aerospace products and services are marketed primarily by its
sales engineers.
 
COMPETITION
   
  Generally, most markets in which New Ametek will operate are highly
competitive. The principal elements of competition for the products
manufactured in each of New Ametek's business segments are price, product
features, distribution, quality and service.     
 
                                      34
<PAGE>
 
  EMG's primary competition in the United States floor-care market consists of
a few competitors, each of which has a smaller market share but is part of a
company with larger and greater resources than New Ametek. There is additional
potential competition from vertically integrated manufacturers of floor-care
products that produce their own motor-blowers. Many of these manufacturers are
also potential EMG customers if they outsource their motors. In Europe,
competition comes from a small group of very large competitors and from
numerous small competitors.
   
  In the markets it serves, PI is, and New Ametek believes it will continue to
be, one of the world's largest pressure gauge manufacturers and ranks among
the leading United States producers of certain measuring and control
instruments. It is one of the leading instrument and sensor suppliers to
commercial aviation. Competition is strong and could intensify for certain
aerospace products. In the pressure gauge and heavy-vehicle markets served by
PI, only a limited number of companies compete on price and technology. In the
process and analytical instrument markets, numerous companies in each market
niche compete on the basis of product quality, performance and innovation.
    
  Many of the products sold by IMG are made by a few competitors, and
competition comes mainly from producers of substitute materials. The primary
competition is from competitive materials and processes.
 
BACKLOG AND SEASONAL VARIATIONS OF BUSINESS

</TABLE>    
   
  Of the total backlog of unfilled orders at March 31, 1997, approximately 86%
of the orders are expected to be shipped by December 31, 1997.     
 
  New Ametek believes that neither its business as a whole nor any of its
business segments is subject to significant seasonal variations, although
certain individual operations experience some seasonal variability.
 
RAW MATERIALS
 
  AMETEK's business segments obtain raw materials and supplies from a variety
of sources and generally from more than one supplier. However, in the
Industrial Materials segment, certain items are available only from a limited
number of suppliers. New Ametek believes these sources and supplies of raw
materials will be adequate for its needs.
          
INTERNAL REINVESTMENT     
   
 Capital Expenditures     
   
  Capital expenditures were $6.6 million for the three months ended March 31,
1997 and $39.1 million in 1996, compared to $29.3 million in 1995, an increase
of $9.7 million or 33.2%. Approximately 77% of the 1997 expenditures and 83%
of the 1996 expenditures were for additional manufacturing equipment to
increase production efficiencies, and for expanded production capacity,
primarily in the Electromechanical Group. New Ametek expects to increase its
total capital spending in 1997 slightly above 1996 levels, with continued
emphasis on investment in production efficiencies and expansion, primarily in
the Electromechanical Group.

<PAGE>
 
   
 Product Development and Engineering     
   
  Product development and engineering expenses for the three months ended
March 31, 1997 totaled $8.6 million. Such amounts were $35.9 million in 1996
compared to $32.0 million in 1995, and $31.9 million in 1994. These amounts
include net expenses for research and development of $4.2 million for the
three months ended March 31, 1997, $17.1 million in 1996, $15.5 million in
1995, and $17.3 million in 1994. Such expenditures were directed toward the
development of new products and processes, and the improvement of existing
products and processes.     
 
ENVIRONMENTAL COMPLIANCE
   
  New Ametek is subject to environmental laws and regulations generally
applicable to all United States manufacturing companies. AMETEK has been named
as a potentially responsible party at several sites which are the subject of
government-mandated clean-ups and, pursuant to the Distribution Agreement, New
Ametek will assume responsibility for these matters. Charges to expense for
environmental cleanup at those sites and other sites were approximately $.5
million for the three months ended March 31, 1997, $1.8 million in 1996, $2.4
million in 1995, and $1.6 million in 1994. New Ametek will assume
responsibility for any potential environmental liability, and in the future
may require higher capital expenditures and expenses. While it is not possible
to quantify the potential financial impact of actions regarding environmental
matters, New Ametek believes that the outcome of these actions is not likely
to have a material adverse effect on its future results of operations,
financial position or cash flow.     
 
PATENTS, LICENSES AND TRADEMARKS
 
  AMETEK owns, and New Ametek will own, numerous unexpired United States
patents, United States design patents and foreign patents, including
counterparts of its more important United States patents, in the major
industrial countries of the world. AMETEK is, and New Ametek will be, a
licensor or licensee under patent agreements of various types and its products
are marketed under various registered United States and foreign trademarks and
trade names. However, New Ametek does not consider any single patent or
trademark, or any group of them, essential to its business as a whole, or to
any of its business segments. The annual royalties received or paid under
license agreements are not significant to any single business segment or to
New Ametek's overall operations.
 
EMPLOYEES
   
  At March 31, 1997, New Ametek employed approximately 6,200 individuals.     
 
PROPERTIES
   
  New Ametek has 33 operating plant facilities in 13 states and seven foreign
countries. Of these facilities, 25 are owned by New Ametek and eight are
leased. The properties owned by New Ametek consist of approximately 414 acres
in total, of which approximately 3,086,000 square feet are under roof, and
include property recently purchased in the Czech Republic for its
Electromechanical Group, where operations will begin later in 1997. Under
lease is a total of approximately 550,000 square feet. The leases expire over
a range of years from 1997 to 2009 with renewal options for varying terms
contained in most of the leases. Production facilities in Taiwan and the PRC
provide New Ametek with additional production capacity through New Ametek's
50% ownership in a joint venture. New Ametek also owns certain parcels of land
that are pending sale. New Ametek's executive offices in Paoli, Pennsylvania
occupy approximately 34,000 square feet under a lease that will expire in
2002.

  New Ametek's machinery, plants and offices are in satisfactory operating
condition and are adequate for the uses to which they are put. The principal
operating facilities of New Ametek by business segment are summarized in the

OTHER MATTERS     
   
  In cooperation with the Consumer Products Safety Commission, the Water
Filtration Business, along with its supplier and customer, is participating in
a voluntary recall of a water filter cartridge model involving 14,000 units
which were sold, through a mass merchandiser, beginning in March 1996, when
the water filter cartridges were introduced. Although only a limited number of
the water filter cartridges contain an incorrect form of carbon, all units
have been recalled as a precautionary measure. New Ametek does not believe it
is liable in this matter and based upon currently available information, New
Ametek's management does not believe the outcome will have a material adverse
effect on New Ametek's financial position or results of operations.

COMMITTEES OF THE BOARD OF DIRECTORS
 
  New Ametek will establish, effective as of the Spin-Off Date, the following
committees: an Audit Committee, a Compensation Committee, a Nominating
Committee and a Pension Investment Committee, all of which are comprised of
non-employee directors.
 
  In addition, New Ametek will have an Executive Committee comprised of two or
more Directors which will meet on an as needed basis when the New Ametek Board
is not in session. This Committee may exercise all the power of the Board of
Directors in the management of the business and affairs of New Ametek except
the power to fill vacancies of the New Ametek Board or to change members of or
fill vacancies in the committee or to make or amend the New Ametek By-Laws.
 
  The functions of the Audit Committee will include: reviewing with
independent auditors the plan and results of the audit engagement; reviewing
the scope and results of New Ametek's procedures for internal auditing; and
reviewing the adequacy of New Ametek's system of internal accounting controls.
 
  The functions of the Compensation Committee's non-employee directors will
include: study and analysis of and recommendations to the New Ametek Board
concerning specific and general matters of management compensation; periodic
review of management compensation policies and practices; recommendations to
the New Ametek Board regarding incentive compensation awards and officers'
salary adjustments; and administrative oversight of stock option plans and
other incentive and compensation plans.
 
  The functions of the Nominating Committee will include: determining an
appropriate size and composition of the New Ametek Board; considering
qualifications of prospective New Ametek Board candidates; conducting research
to identify and recommend nomination of suitable candidates; and reviewing the
experience, background, interests, ability and availability of prospective
nominees to meet time commitments of the New Ametek Board and committee
responsibilities.
 
  The Pension Investment Committee will review the administration of New
Ametek's retirement plans, including compliance, investment manager and
trustee performance and results of independent audits of the plans.
 
COMPENSATION OF DIRECTORS
 
  The annual rate of compensation for services as a nonemployee director of
New Ametek will be $35,000 plus $2,500 for each New Ametek Board meeting
attended. Employee directors will not receive compensation for services as a
director. At present, Mr. Blankley is the only employee director of New
Ametek.
   
  Pursuant to a Retirement Plan for Directors (the "Directors Plan"), New
Ametek will provide retirement benefits and death benefits to those directors
who have not accrued benefits under the Employees' Retirement Plan of AMETEK,
Inc. and who have completed at least three years of service as a director or
officer of New Ametek (including service as a director or officer of AMETEK).
Effective as of the Spin-Off Date, New Ametek will assume all obligations
accrued under, and will continue to provide for, the Directors Plan. Effective
January 1, 1997, the Directors Plan was amended to limit participation to
those Directors who became members of the Board of Directors prior to January
1, 1997. The retirement benefit payable under the Directors Plan is an annual
amount equal to 100% of the highest annual rate of compensation for directors
during the director's period of service on the Board of Directors; however,
the benefit is reduced proportionately if the participant has less than five
years of service. New Ametek shall satisfy its obligations arising under the
Directors Plan exclusively from its general assets. All of the current AMETEK
directors other than Mr. Blankley are participants in the Directors Plan and
each of these participants, other than Messrs. Malone and Steinmann, has
accrued an annual retirement benefit of $50,000. Mr. Steinmann has accrued an
annual retirement benefit of $40,000, and Mr. Malone has accrued an annual
retirement benefit of $30,000.     
 
  Pursuant to a Death Benefit Program for Directors (the "Directors Program"),
New Ametek will enter into individual agreements with certain directors. The
agreements will require New Ametek to pay death benefits to directors'
designated beneficiaries and to pay benefits to the directors under certain
circumstances. Effective as of the Spin-Off Date, New Ametek will assume all
AMETEK obligations accrued under, and will continue to
 
                                      40
<PAGE>
 
provide for, the Directors Program. The Directors Program currently provides
for a benefit, payable for ten years, in an annual amount equal to 100% of the
highest annual rate of compensation during the director's period of service on
the Board of Directors, commencing at death or the later of age 70 or
retirement; however, with respect to directors who became participants after
January 1, 1989, the directors must complete at least five years of service as
a director before they become eligible to receive a benefit upon the later of
age 70 or retirement. Active directors will also have a group term life
insurance benefit of $50,000. To fund benefits under the Directors Program,
AMETEK has purchased, and New Ametek will continue to purchase, individual
life insurance policies on the lives of certain of the covered directors. New
Ametek will retain the right to terminate any or all of the Directors Program
agreements under certain circumstances. All of the current directors other
than Mr. Blankley currently participate in the Directors Program.
 
COMPENSATION OF EXECUTIVE OFFICERS
   
  The following sets forth certain information with respect to the executive
officers of AMETEK, who effective as of the Spin-Off Date, will become
executive officers of New Ametek. All executive officers are elected by the
New Ametek Board to hold office until the next annual meeting of stockholders
and thereafter until their successors are elected and qualified. The following
executive officers of New Ametek and its subsidiaries were nominated for
election at the April 14, 1997 meeting of the Nominating Committee and were
elected at the June  , 1997 meeting of the New Ametek Board to take effect on
the Spin-Off Date, and all held the same positions at AMETEK. Effective as of
the Spin-Off Date, New Ametek will assume liability for all compensation owed
by AMETEK and will continue to pay executive compensation at rates comparable
to those included in the following table.     
 
 Executive Compensation Prior to the Spin-Off
 
  The following table sets forth certain information for the fiscal year ended
December 31 in each of 1996, 1995 and 1994 concerning compensation paid or

 Employment Contracts and Termination, Severance and Change-in-Control
Provisions
   
  AMETEK has entered into change of control agreements with most of its
executive officers, including the executives listed in the Summary
Compensation Table, which agreements New Ametek will assume effective as of
the Spin-Off Date. The purpose of these agreements is to assure the continued
attention and dedication of key executives when AMETEK is faced with a
potential Change of Control (as defined below) by providing for some
continuation of the executive's compensation and benefits. Under the
agreements, the sum of the executive's prior year's salary plus the greater of
(a) the current year's bonus, or (b) the average of the two prior years'
bonuses (as limited under Section 280G of the Code) will be continued for a
period of one, two or three years (as defined in each executive's agreement),
and health benefits will be continued until Medicare eligibility, coverage
under another group health plan, ten years or the executive's death, whichever
is earlier, in the event that the executive's employment is terminated by
AMETEK without cause or by the executive for good reason within two years
after a Change of Control. For purposes of the agreements, a "Change of
Control" means the acquisition of 20% or more of the voting stock of New
Ametek by a party other than New Ametek (or its affiliates), or a merger or
consolidation after which the stockholders of New Ametek do not own or control
at least 50% or more of the voting stock of New Ametek, or any sales or other
disposition of all or substantially all of New Ametek's assets, or a plan of
liquidation is approved. None of the events related to the Spin-Off or the
Merger will be deemed to constitute a Change of Control.     
 
  Pursuant to a Supplemental Senior Executive Death Benefit Program (the
"Program"), AMETEK has entered into individual agreements, which New Ametek
will assume, with certain executives. The agreements require AMETEK, and will
require New Ametek, to pay death benefits to their designated beneficiaries
and to pay benefits to the executives under certain circumstances. Effective
as of the Spin-Off Date, New Ametek will assume all obligations accrued under,
and will continue to provide for, the Program. If a covered executive dies
before retirement or before age 65 while on disability retirement, the
executive's beneficiary will receive monthly payments from the date of the
executive's death until the date he or she would have attained age 80, but not
less than for 15 years (the 15-year minimum guarantee does not apply to
executives whose inclusion in the Program is approved after December 31,
1986). The specified dollar amount of the payments is determined on the basis
of the executive's salary and age. In addition, the standard death benefit
payable to all salaried personnel from AMETEK's group term life insurance
policy is two times the executive's annual salary, limited to $200,000. If a
covered executive retires, or reaches age 65 while on disability retirement,
the Program provides for an annual benefit of one-tenth of an amount equal to
the lesser of (a) twice the executive's average annual base salary for the
last five full years of service, rounded off to the next highest multiple of
$50,000 or (b) a maximum amount specified in the agreement. The highest
maximum amount specified in the existing agreements is $1,000,000. The benefit
is payable monthly over a period of 10 years to the executive or the
executive's beneficiary. The payments will commence for retirees at age 70 or
death, whichever is earlier. However, if the executive retires after age 70,
the payments commence on retirement.
 
  To fund benefits under the Program, AMETEK has purchased, and New Ametek
will continue to maintain, individual life insurance policies on the lives of
certain of the covered executives. New Ametek will retain the right to
terminate all of the Program agreements under certain circumstances. Messrs.
Blankley, Hermance, Marsinek, Molinelli and Neupaver are participants in the
Program.

OPTION GRANTS OF AMETEK COMMON STOCK IN 1996
 
  The following table provides information on stock options to purchase AMETEK
Common Stock granted in 1996 to the Chief Executive Officer and the other
executive officers named in the Summary Compensation Table. In addition, the
table provides the hypothetical gains or "option spreads" that would result
for the respective options based on assumed rates of annual compound stock
price appreciation of 5% and 10% from the date the options were granted
through their expiration dates. No stock appreciation rights ("SARs") were
granted to the named executive officers in 1996. Pursuant to the terms of the
Distribution Agreement, effective as of the Spin-Off Date, these stock options
will be converted to options to purchase New Ametek Common Stock.

(1) The options granted in 1996 to Messrs. Blankley, Hermance, Marsinek,
    Molinelli and Neupaver are exercisable after the first anniversary of the
    date of the grant (April 8, 1996) during each of the four succeeding
    twelve-month periods only to the extent of twenty-five percent of the
    total number of shares optioned. In all cases, optioned shares that may
    have been but were not purchased during any one twelve-month period may be
    purchased during any one or more succeeding twelve-month periods up to the
    expiration date of the option. Options generally become fully exercisable
    in the event of the holder's death, retirement or termination of
    employment in connection with a change in control.
(2) The amounts represent certain assumed rates of appreciation. Actual gains,
    if any, on stock option exercises are dependent on future performance of
    New Ametek's Common Stock. There can be no assurance that the rates of
    appreciation reflected in this table will be achieved.

1997 PLAN     
   
  The 1997 Plan was adopted and approved by the New Ametek Board and approved
by the sole stockholder of New Ametek effective               , 1997. The
purpose of the 1997 Plan is to encourage New Ametek's key employees and
directors to acquire a larger proprietary interest in New Ametek and to
provide incentives to maximize the long-term growth of New Ametek. The 1997
Plan is administered by a committee (the "Incentive Committee") comprised of
two or more directors of New Ametek who are not employees of New Ametek ("Non-
Employee Directors") and who are "outside directors" as defined in Section
162(m) of the Code. The Incentive Committee has full authority to interpret
the 1997 Plan and to establish rules for its administration.     
   
  Under the 1997 Plan, the aggregate number of shares of New Ametek Common
Stock that may be issued pursuant to stock options, restricted stock awards,
phantom stock awards (other than any phantom stock awards which are payable
only in cash), or stock appreciation rights may not exceed [     ]. A maximum
of [15]% of the aggregate number of shares, or [     ] shares, may be awarded
to any single individual during the duration of the 1997 Plan. A maximum of
[10]% of the aggregate number of shares, or [     ] shares, may be awarded as
restricted stock. In the event New Ametek adopts a stock purchase plan for the
benefit of its employees, the shares of New Ametek Common Stock awarded under
that plan shall further reduce the aggregate number of shares available under
the 1997 Plan. The number of shares issuable under the 1997 Plan has been
calculated to provide for the estimated number of shares needed to replace
currently outstanding shares under AMETEK's prior stock incentive plans in
accordance with the terms of the Spin-Off and the Merger, and to have
available for issuance of new grants the same number of shares as are now
available for new grants under such prior plans.     
   
  All key employees are eligible to participate in the 1997 Plan. In addition,
directors whose initial appointment to the New Ametek Board is on or after the
effective date of the 1997 Plan (except for directors who are partners in the
law firm retained as general counsel to New Ametek) will be granted a non-
qualified stock option of 20,000 shares of common stock. The amount of
individual awards to key employees will be determined by the Incentive
Committee, subject to the limitations of the 1997 Plan. The Incentive
Committee can grant non-qualified options and options qualifying as incentive
stock options under the Code. The term of an option cannot exceed ten years
from the date of grant. In determining the amount and form of an award,
consideration will be given to the function and responsibilities of the key
employee, his or her potential contributions to the success of New Ametek, and
other factors deemed relevant by the Incentive Committee.

DEFINED BENEFIT AND ACTUARIAL PLANS
 
  The Employees' Retirement Plan of AMETEK, Inc. (the "Retirement Plan") is a
noncontributory defined benefit pension plan under which contributions are
actuarially determined. Effective as of the Spin-Off Date, New Ametek will
assume all obligations accrued under, and continue to provide for, the
Retirement Plan. The following table sets forth the estimated annual benefits,
expressed as a single life annuity, payable upon retirement (assuming normal
retirement at age 65) under the Retirement Plan for individuals with the
indicated years of service and at the indicated compensation levels (without
taking into account statutory restrictions incorporated in the Retirement Plan
and described below):

- --------
(1) Benefit amounts assume a participant reaches age 65 in 1997; for younger
  participants, the benefit amounts are less than the amounts indicated above.
   
  At December 31, 1996 the executives named in the Summary Compensation Table
had the following years of credited service under the Retirement Plan: Mr.
Blankley-37; Mr. Hermance-6; Mr. Marsinek-32; Mr. Molinelli-28; and Mr.
Neupaver-20.     
   
  The annual compensation taken into account for any plan year is generally
equal to the participant's salary and any bonus accrued during the plan year
as reported in the Summary Compensation Table. Compensation in excess of
certain amounts prescribed by the Secretary of the Treasury ($160,000 for
1997) cannot be taken into account under the Retirement Plan. The individuals
named in the Summary Compensation Table are subject to this limitation.
However, in accordance with a nonqualified supplemental pension arrangement
that, as of the Spin-Off Date, New Ametek will assume, AMETEK has agreed to
provide to Mr. Blankley a benefit in an amount equal to the excess of the
annual pension benefit that would be payable to him under the terms of the
Retirement Plan in the absence of statutory restrictions over the amount
actually payable under the Retirement Plan. The benefit is limited to the
projected excess payable at age 65 determined as of May 21, 1991, taking into
account the statutory restrictions as of such date. Pursuant to an agreement
entered into with Mr. Blankley, a restricted stock award was granted under the
1991 Stock Incentive Plan of AMETEK, Inc. for a number of shares of AMETEK
Common Stock having a fair market value on the day of grant equal to 50% of
the then present value of Mr. Blankley's projected benefit under the
supplemental pension arrangement. Effective with the Spin-Off and the Merger,
shares of New Ametek Common Stock and Culligan Common Stock will be
substituted for the AMETEK Common Stock in amounts consistent with the terms
of the Spin-Off and the Merger. The remaining portion of the benefit will be
payable in cash directly out of New Ametek's general assets. Under this
arrangement, Mr. Blankley does not receive an amount necessary to provide him
with his full benefit under the Retirement Plan, since the amount of
compensation that can be taken into account under the statutory restrictions
in effect in 1991 has subsequently been reduced.     
 
                                      45
<PAGE>
 
   
  In addition, pursuant to the AMETEK, Inc. Supplemental Executive Retirement
Plan ("SERP") that, as of the Spin-Off Date, New Ametek will assume, AMETEK has
agreed, beginning in 1997, to credit to the account of certain executives,
including executives named in the Summary Compensation Table, an amount equal
to 13% of the executive's compensation in excess of the statutory restrictions
for each plan year, in order to compensate them for the loss of retirement
income under the Retirement Plan resulting from those restrictions. The
contribution for Mr. Blankley under the SERP will be limited to 13% of his
compensation that is not taken into account under the agreement described in
the preceding paragraph. The credited amounts shall be deemed to be invested in
AMETEK Common Stock and, upon retirement, shall be distributed in kind. In
addition, a one-time credit shall also be made to each such executive's account
equal to the value of the shares of common stock, if any, that would have been
credited to the executive's account had the SERP been in effect since January
1, 1989. An executive's right to a benefit under the SERP will become non-
forfeitable at the same time as the executive's right to an accrued benefit
under the Retirement Plan (or the retirement feature of The AMETEK Savings and
Investment Plan) becomes non-forfeitable.     
          
  For retirements occurring in 1997, the maximum annual pension benefit payable
at normal retirement age from the Retirement Plan is restricted, by law, to the
greater of $125,000 or the amount of such benefit determined under the
Retirement Plan and prior existing law as of December 31, 1982. The $125,000

increases in the cost of living.     
   
  Persons joining AMETEK or New Ametek after January 1, 1997 are not eligible
to participate in the Retirement Plan, but instead are eligible to participate
in a new defined contribution retirement feature of The AMETEK Savings and
Investment Plan.

                    DESCRIPTION OF NEW AMETEK CAPITAL STOCK
 
  The summary of the terms of the stock of New Ametek set forth below does not
purport to be complete and is subject to and qualified in its entirety by
reference to the New Ametek Certificate and the New Ametek By-Laws.
 
AUTHORIZED CAPITAL STOCK
 
  Under the New Ametek Certificate, the total number of shares of all classes
of stock that New Ametek has authority to issue is 105,000,000 shares, of
which 100,000,000 are shares of New Ametek Common Stock and 5,000,000 are
shares of New Ametek Preferred Stock, par value $1.00 per share (the "New
Ametek Preferred Stock").
 
COMMON STOCK
 
  Holders of New Ametek Common Stock will be entitled to one vote per share on
all matters voted on generally by the stockholders, including the election of
directors, and, except as otherwise required by law or except as provided with
respect to any series of New Ametek Preferred Stock, the holders of such
shares will possess all voting power. The New Ametek Certificate does not
provide for cumulative voting for the election of directors. Thus, under the
DGCL, the holders of more than one-half of the outstanding shares of New
Ametek Common Stock generally will be able to elect all the directors of New
Ametek then standing for election and holders of the remaining shares will not
be able to elect any director.
 
  Subject to any preferential rights of any series of New Ametek Preferred
Stock, holders of shares of New Ametek Common Stock will be entitled to
receive dividends on such stock out of assets legally available for
distribution when, as and if authorized and declared by the New Ametek Board
and to share ratably in the assets of New Ametek legally available for
distribution to its stockholders in the event of its liquidation, dissolution
or winding up.
 
  Holders of New Ametek Common Stock will have no preferences, preemptive,
conversion or exchange rights.
 
  Certain of the foregoing provisions of the New Ametek Certificate may make
more difficult, and therefore discourage, attempts to acquire control of New
Ametek through acquisitions of shares of New Ametek Common Stock or otherwise,
in transactions not approved by the New Ametek Board. As a result of these
provisions, transactions or proposed transactions which might have the short-
term effect of increasing the market price of New Ametek Common Stock may be
discouraged, and management of New Ametek may be able to resist changes which
the stockholders might otherwise have the power to impose. The division of the
New Ametek Board into three classes could discourage third parties from
seeking to acquire control of such Board and could impede proxy contests or
other attempts to change New Ametek's management.
 
PREFERRED STOCK
 
  The New Ametek Board is authorized to issue shares of New Ametek Preferred
Stock, in one or more series or classes, and to fix for each such series
voting powers and such preferences and relative, participating, optional or
other special rights and such qualifications, limitations or restrictions as
are permitted by the DGCL. No shares of New Ametek Preferred Stock are
currently outstanding. The New Ametek Board could authorize the issuance of
shares of New Ametek Preferred Stock with terms and conditions which could
discourage a takeover or other transaction that holders of some or a majority
of shares of New Ametek Common Stock might believe to be in their best
interests or in which such holders might receive a premium for their shares of
stock over the then market price of such shares. Although the New Ametek Board
does not currently intend to issue any shares of New Ametek Preferred Stock,
there can be no assurance that it will not do so in the future.

DESCRIPTION OF CERTAIN STATUTORY, CHARTER AND BY-LAW PROVISIONS
 
 Delaware Anti-Takeover Law
 
  New Ametek is subject to the provisions of Section 203 of the DGCL. Section
203 provides, with certain exceptions, that a Delaware corporation may not
engage in certain business combinations with a person or affiliate or
associate of such person who is an "interested stockholder" for a period of
three years from the date such person became an interested stockholder unless:
(i) the transaction resulting in the acquiring person's becoming an interested
stockholder, or the business combination, is approved by the board of
directors of the corporation before the person becomes an interested
stockholder; (ii) the interested stockholder acquires 85% or more of the
outstanding voting stock of the corporation in the same transaction which
makes it an interested stockholder (excluding certain employee stock option
plans); or (iii) on or after the date the person becomes an interested
stockholder, the business combination is approved by the corporation's board
of directors and by the holders of at least 66 2/3% of the corporation's
outstanding voting stock at an annual or special meeting, excluding shares
owned by the interested stockholder. An "interested stockholder" is defined as
any person that is (x) the owner of 15% or more of the outstanding voting
stock of the corporation or (y) an affiliate or associate of the corporation
and was the owner of 15% or more of the outstanding voting stock of the
corporation at any time within the three year period immediately prior to the
date on which it is sought to be determined whether such person is an
interested stockholder. Under Delaware law, New Ametek could have opted out of
Section 203 but elected to be subject to its provisions.
 
 Classified Board of Directors
 
  The New Ametek Certificate provides for the New Ametek Board to be divided
into three classes of Directors serving staggered three-year terms. As a
result, approximately one-third of the New Ametek Board will be elected each
year.
 
  This provision could prevent a party who acquires control of a majority of
the outstanding voting stock from obtaining control of the New Ametek Board
until the second annual stockholders' meeting following the date the acquiror
obtains the controlling stock interest, and thus could have the effect of
discouraging a potential acquiror from making a tender offer or otherwise
attempting to obtain control of New Ametek. Accordingly, this provision could
increase the likelihood that incumbent New Ametek Directors will retain their
positions.
 
 Number of Directors; Removal; Vacancies
 
  The New Ametek Certificate provides that the number of Directors shall be
determined from time to time by majority of the New Ametek Board, provided
that in no event shall such number be less than three nor more than 12. The
New Ametek By-Laws provide that the New Ametek Board shall have the right to
fill vacancies including vacancies created by expansion of the New Ametek
Board.
 
  The New Ametek Certificate further provides that New Ametek Directors may be
removed only for cause and then only at any annual meeting or special meeting
of the stockholders, the notice of which states that the removal of a Director
or Directors is among the purposes of the meeting, and only by the affirmative
vote of the holders of at least a majority of the voting stock, voting
together as a single class. This provision, in conjunction with the provision
of the New Ametek By-Laws authorizing the New Ametek Board to fill vacant
directorships, would prevent stockholders from removing incumbent New Ametek
Directors without cause and filling the resulting vacancies with their own
nominees.
 
 Stockholder Action by Unanimous Consent; Special Meetings
 
  The New Ametek Certificate provides that any action required or permitted to
be taken by the stockholders of New Ametek must be effected at a duly called
annual or special meeting of stockholders of New Ametek and may not be
effected by any consent in writing of such stockholders. Special meetings of
stockholders of New Ametek may be called only by the Chairman of the Board or
the Corporate Secretary of New Ametek within 10
 
                                      50
<PAGE>
 
calendar days after receipt of the written request of a majority of the total
number of Directors which New Ametek would have if there were no vacancies. At
an annual meeting or special meeting of stockholders of New Ametek, only such
business will be conducted or considered as has been brought before such
meeting in the manner provided in the New Ametek By-Laws.
 
 Advance Notice for Raising Business or Making Nominations at Meetings
 
  The New Ametek By-Laws establish an advance notice procedure for business
being brought before an annual meeting of stockholders of New Ametek by the
stockholders and for nominations by the stockholders of candidates for
election as New Ametek Directors at an annual meeting or a special meeting
called for the purpose of electing such Directors. Subject to applicable law,
including, without limitation, Rule 14a-8 under the Exchange Act, only such
business may be conducted at an annual meeting as has been brought before the
meeting by, or at the direction of, the New Ametek Board, or by a stockholder
who has given to the Corporate Secretary of New Ametek timely written notice,
in proper form, of the stockholder's intention to bring that business before
the meeting. In addition, only persons who are nominated by, or at the
direction of the New Ametek Board, or who are nominated by a stockholder who
has given timely written notice, in proper form, to the Corporate Secretary of
New Ametek prior to a meeting at which New Ametek Directors are to be elected
will be eligible for election as Directors of New Ametek.
 
  To be timely, notice of nominations or other business to be brought before
an annual meeting must be received by the Corporate Secretary of New Ametek
not less than 60 nor more than 90 days prior to the meeting; however, if the
date of the meeting is first publicly announced or disclosed less than 75 days
prior to the date of the meeting, notice shall be given not more than 10 days
after such date is first announced or disclosed. Similar advance notice
requirements are applicable to nominations to be brought before a special
meeting called for the purpose of electing Directors.
 
 Amendment of Certain Charter and By-Law Provisions
 
  The New Ametek Certificate provides that the New Ametek Board may adopt,
amend, or repeal any provision of the New Ametek By-Laws. Any By-Law made by
the New Ametek Board may be amended or repealed by the New Ametek Board or by
the stockholders in the manner provided in the New Ametek By-Laws.
Notwithstanding the foregoing, certain New Ametek By-Laws may not be amended
or repealed by the stockholders, and no provision inconsistent therewith may
be adopted by the stockholders, without the affirmative vote of the holders of
at least 80% of the voting stock, voting together as a single class. The New
Ametek By-Laws may be amended or repealed at any time, either at any meeting
of stockholders, provided that any amendment or supplement proposed to be
acted upon at any such meeting has been described or referred to in the notice
of such meeting, or at any meeting of the New Ametek Board, provided that no
amendment adopted by the New Ametek Board may vary or conflict with any
amendment adopted by the stockholders.
 
 Transfer Agent and Registrar
   
  The transfer agent and registrar for New Ametek Common Stock will be
American Stock Transfer & Trust Company.     
 
DESCRIPTION OF STOCKHOLDERS' RIGHTS PLAN
   
  The New Ametek Board, on June   , 1997, adopted a Stockholders' Rights Plan
(the "Rights Plan") to be effective on the Spin-Off Date under which one right
(a "Right") will be issued with respect to each share of New Ametek Common
Stock. Each Right will entitle the holder to purchase from New Ametek one one-
hundredth of a share of Series A Junior Participating Preferred Stock, par
value $.01 per share (the "Series A Preferred Stock"), at a purchase price to
be determined by New Ametek's Board, subject to adjustment in certain events
(the "Purchase Price"). The following summary description of the Rights does
not purport to be complete and is qualified in its entirety by reference to
the proposed form of Rights Agreement between New Ametek and a Rights Agent
(the "Rights Agreement"), a copy of which is filed as an exhibit to the
Registration Statement of which this Information Statement is a part and is
incorporated herein by reference.     
 
                                      51
<PAGE>
 
   
  Initially, the Rights will attach to all certificates representing
outstanding shares of New Ametek Common Stock and no separate certificates for
the Rights ("Rights Certificates") will be distributed. The Rights will
separate from the New Ametek Common Stock upon the "Distribution Date," which
will occur upon the earlier of (i) 10 days following a public announcement
that a person or group of affiliated or associated persons (an "Acquiring
Person") has acquired beneficial ownership of 20% or more of the outstanding
shares of New Ametek Common Stock (the date of the announcement being the
"Stock Acquisition Date") or (ii) 10 business days following the commencement
of a tender offer or exchange offer that would result in a person becoming an
Acquiring Person or (iii) 10 business days following a determination by New
Ametek's Board that a person has become the beneficial owner of more than 10%
of the outstanding shares of New Ametek Common Stock and (a) has acquired such
beneficial ownership to cause New Ametek to repurchase the shares owned by
such person or to pressure New Ametek to take some action that would provide
such person with short term financial gain under circumstances where the New
Ametek Board determines that the best long-term interests of New Ametek would
not be served by taking such action or (b) such beneficial ownership is
causing or is reasonably likely to cause a material adverse impact on the
business or prospects of New Ametek (any such person, an "Adverse Person").
Until the Distribution Date, (a) the Rights will be evidenced by the New
Ametek Common Stock certificates and will be transferred with and only with
such certificates, (b) New Ametek Common Stock certificates will contain a
legend incorporating the Rights Agreement by reference and (c) the surrender
for transfer of any certificate for New Ametek Common Stock will also
constitute the transfer of the Rights associated with the stock represented by
such certificate.     
 
  The Rights are not exercisable until the Distribution Date and will expire
at the close of business on            , 2007 (the "Final Expiration Date"),
unless earlier redeemed by New Ametek as described below.
 
  As soon as practicable after the Distribution Date, Rights Certificates will
be mailed to holders of record of New Ametek Common Stock as of the close of
business on the Distribution Date, and from the Distribution Date, the
separate Rights Certificates alone will represent the Rights.
 
  In the event (a "Flip-In Event") that (i) a person or group becomes an
Acquiring Person (except pursuant to a tender or exchange offer for all
outstanding shares of New Ametek Common Stock at a price and on terms that a
majority of disinterested Directors, after receiving advice from one or more
investment banking firms, determines to be adequate and otherwise in the best
interests of New Ametek and its stockholders (a "Qualifying Offer")) or (ii)
the Board determines that a person is an Adverse Person, each holder of a
Right will have the right to receive, upon exercise of such Right, a number of
shares of New Ametek Common Stock (or, in certain circumstances, cash,
property or other securities of New Ametek) having a then current market value
of twice the Purchase Price (i.e., at a 50% discount to the then current
market value). Notwithstanding the foregoing, following the occurrence of any
Flip-In Event, all Rights that are, or (under certain circumstances specified
in the Rights Agreement) were, beneficially owned by any Acquiring Person or
an Adverse Person (or by certain related parties) will be null and void in the
circumstances set forth in the Rights Agreement. However, Rights will not be
exercisable following the occurrence of any Flip-In Event until such time as
the Rights are no longer redeemable by New Ametek as set forth below.
 
  In the event (a "Flip-Over Event") that, at any time on or after the Stock
Acquisition Date, (i) New Ametek is acquired in a merger or other business
combination in which New Ametek is not the surviving corporation, (ii) New
Ametek is the continuing or surviving corporation in a merger but all or part
of the outstanding shares of New Ametek Common Stock is changed into or
exchanged for stock or securities of any other person or cash or property, or
(iii) 50% or more of New Ametek's assets or earning power is sold or
transferred (in one transaction or a series of related transactions), then
each holder of a Right (except Rights that have been voided as set forth
above) thereafter shall have the right to receive, upon exercise at the then
current Purchase Price (as set forth in the Rights Agreement), a number of
shares of common stock of the acquiring company having a then current market
value of twice such Purchase Price (i.e., at a 50% discount). New Ametek may
not engage in a transaction with an Acquiring Person constituting a Flip-Over
Event unless the Acquiring Person meets certain conditions. If the Acquiring
Person's (or its affiliated entity's) common stock has not been registered
under the
 
                                      52
<PAGE>
 
Exchange Act, for the preceding twelve months, but it is a direct or indirect
subsidiary of another company which has registered common stock, the Rights
shall be exercisable as described above to purchase the common stock of such
parent company. Moreover, New Ametek may not engage in a flip-over transaction
unless the Acquiring Person (or its affiliated entity or parent, as
applicable), (i) has sufficient shares of common stock authorized to permit
the full exercise of the Rights and (ii) enters into an agreement containing
the terms set forth above and providing that, as soon as practicable after the
date of the Flip-Over Event, the Acquiring Person will register the Rights and
the securities issuable upon exercise of the Rights under the Securities Act
and maintain the effectiveness of such registration statement until the
Expiration Date of the Rights Plan. Notwithstanding the foregoing, a merger or
consolidation will not constitute a Flip-Over Event if (i) the transaction is
consummated with a person who acquired New Ametek Common Stock pursuant to a
Qualifying Offer or with a subsidiary of such person; (ii) the price per share
of Common Stock offered in such transaction is not less than the price paid to
holders of New Ametek Common Stock whose shares were purchased in the
Qualifying Offer; and (iii) the form of consideration offered in the
transaction is the same as the form of consideration paid pursuant to the
Qualifying Offer.
 
  The Purchase Price payable, and the number of shares of Series A Preferred
Stock or other securities or property issuable, upon exercise of the Rights
are subject to adjustment from time to time to prevent dilution (i) in the
event of a stock dividend on (payable in shares of the Series A Preferred
Stock), or a subdivision, combination or reclassification of, the Series A
Preferred Stock, (ii) if holders of the Series A Preferred Stock are granted
certain rights or warrants to subscribe for Series A Preferred Stock or
certain convertible securities at less than the current market price of the
Series A Preferred Stock or (iii) upon the distribution to holders of the
Series A Preferred Stock of evidence of indebtedness or cash (other than a
regular quarterly cash dividend out of the earnings or retained earnings of
New Ametek) or assets (excluding regular quarterly cash dividends and
dividends payable in shares of Series A Preferred Stock) or of subscription
rights or warrants (other than those referred to above). With certain
exceptions, no adjustment in the Purchase Price will be required until
cumulative adjustments amount to at least 1% of the Purchase Price. Fractional
shares of Series A Preferred Stock in integral multiples of one one-hundredth
of a share of Series A Preferred Stock will be issuable. In lieu of fractional
shares other than fractions that are multiples of one one-hundredth of a
share, an adjustment in cash will be made based on the market price of the
Series A Preferred Stock on the last trading date prior to the date of
exercise.
   
  At any time until the earlier of (a) 10 days following the Stock Acquisition
Date or (b) the Final Expiration Date, New Ametek may redeem the Rights in
whole, but not in part, at a price of $.01 (subject to certain adjustments as
set forth in the Rights Agreement) per Right, payable, at the option of New
Ametek, in cash, shares of New Ametek Common Stock or such other consideration
as the New Ametek Board may determine. The New Ametek Board may not, however,
redeem any rights following a determination by the Board that any person is an
Adverse Person. Additionally, the 10 day period following the Stock
Acquisition Date during which the Rights may be redeemed may be extended by
the Directors during such 10 day period. However, if the Rights are not so
redeemed during such 10 day period (or any extension thereof), the Rights
shall become non-redeemable for the duration of the Rights Plan. Immediately
upon the effectiveness of the action of the New Ametek Board ordering
redemption of the Rights, the Rights will terminate and the only right of the
holders of Rights will be to receive the $.01 redemption price.     
 
  In the event that a majority of the New Ametek Board serving following a
meeting of stockholders or stockholder action by written consent are not
nominated by the New Ametek Board serving immediately prior to such meeting or
action, then for 180 days following such meeting or action the Rights may not
be redeemed if such redemption is reasonably likely to have the purpose or
effect of allowing any person to become an Acquiring Person, or otherwise
facilitating the occurrence of a Flip-In Event, or a Flip-Over Event or a
transaction with an Acquiring Person.
 
  The Series A Preferred Stock purchasable upon exercise of the Rights will be
junior to any other series of preferred stock New Ametek may issue (unless
otherwise provided in the terms of such series). Each share of Series A
Preferred Stock will entitle the holder thereof to receive a preferential
quarterly dividend in an amount
 
                                      53
<PAGE>
 
equal to the greater of $     or 100 times the dividend declared on each share
of New Ametek Common Stock. In the event of liquidation, the holders of Series
A Preferred Stock will receive a preferred liquidation payment equal to $
per share, plus an amount equal to accrued and unpaid dividends thereon to the
date of such payment (the "Series A Liquidation Preference"). Following such
payment, the holders of New Ametek Common Stock will receive an amount per
share equal to the quotient obtained by dividing (i) the Series A Liquidation
Preference by (ii) 100 (the "Adjustment Amount"). Following the full payment
of the Series A Liquidation Preference and the Adjustment Amount, holders of
Series A Preferred Stock and New Ametek Common Stock shall receive their
ratable and proportionate share of the remaining assets to be distributed in
the ratio of 100 to one with respect to such Series A Preferred Stock and New
Ametek Common Stock, on a per share basis, respectively. Each share of Series
A Preferred Stock will have 100 votes, voting together with the shares of New
Ametek Common Stock. In the event six quarterly cumulative dividends, whether
consecutive or not, on the Series A Preferred Stock are in arrears, the
holders of Series A Preferred Stock will have the right, voting as a class, to
elect two members of the New Ametek Board (in addition to their normal voting
rights) until all unpaid dividends on the Series A Preferred Stock have been
paid in full.
 
  In the event of any consolidation, merger or other transaction in which
shares of New Ametek Common Stock are exchanged, each share of Series A
Preferred Stock will be entitled to receive 100 times the amount and type of
consideration received per share of New Ametek Common Stock. The rights of the
Series A Preferred Stock as to dividends, liquidation payments and voting, and
in the event of mergers or consolidations, are protected by customary anti-
dilution provisions.
 
  Except as provided above, any of the provisions of the Rights Agreement may
be amended by the New Ametek Board prior to the Distribution Date. Thereafter,
the provisions of the Rights Agreement may be amended by the New Ametek Board
in order to cure any ambiguity, defect or inconsistency, to make changes that
do not adversely affect the interests of holders of Rights (excluding the
interest of any Acquiring Person or Adverse Person), or to shorten or lengthen
any time period under the Rights Agreement; provided, however, that an
amendment to lengthen the time period governing redemption may be made only if
the Rights are redeemable and an amendment to lengthen any other time period
may be made only for the purpose of protecting, enhancing or clarifying the
rights of, and/or benefits to, the holders of Rights (other than any Acquiring
Person or Adverse Person). Until a Right is exercised, the holder thereof, as
such, will have no rights as a stockholder of New Ametek, including, without
limitation, the right to vote or to receive dividends.
 
  The Rights will have certain anti-takeover effects. The Rights will cause
substantial dilution to any person or group that attempts to acquire New
Ametek without the approval of New Ametek's Board. As a result, the overall
effect of the Rights may be to render more difficult or discourage any attempt
to acquire New Ametek even if such acquisition may be favorable to the
interests of New Ametek's stockholders. Because New Ametek's Board can redeem
the Rights or approve a Qualifying Offer, the Rights should not interfere with
a tender offer, merger or other business combination approved by the New
Ametek Board.
 
  The distribution of the Rights should not be taxable to stockholders of New
Ametek. However, depending upon the circumstances, shareholders may recognize
taxable income if the Rights become exercisable or upon the occurrence of
certain events thereafter.

            LIABILITY AND INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Section 145 of the DGCL provides, in summary, that directors and officers of
Delaware corporations are entitled, under certain circumstances, to be
indemnified against all expenses and liabilities (including attorneys' fees)
incurred by them as a result of suits brought against them in their capacity
as a director or officer, if they acted in good faith and in a manner they
reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe their conduct was unlawful; provided, that no
indemnification may be made against expenses in respect of any claim, issue or
matter as to which they shall have been adjudged to be liable to the
corporation, unless and only to the extent that the court in which such action
or suit was brought shall determine upon application that, despite the
adjudication of liability but in view of all the circumstances of the case,
they are fairly and reasonably entitled to indemnity for such expenses which
such court shall deem proper. Any such indemnification may be made by the
corporation only as authorized in each specific case upon a determination by
the stockholders or disinterested directors that indemnification is proper
because the indemnity has met the applicable standard of conduct.
 
  The New Ametek Certificate and By-Laws provide that New Ametek shall
indemnify, to the full extent authorized or permitted by law (as now or
hereafter in effect), any person involved, or threatened to be involved,
including, without limitation as a party or witness, in any action, suit or
proceeding (whether civil or criminal or otherwise) by reason of the fact that
such person (including the heirs, executors, administrators or estate of such
person), is or was a director, officer, employee or agent of New Ametek or by
reason of the fact that such director or officer, at the request of New Ametek
is or was serving at any other corporation, partnership, joint venture, trust
or other entity, in any capacity. The New Ametek Certificate and By-Laws
further provide that New Ametek may purchase and maintain insurance on behalf
of any person who is or was a director, officer, employee or agent of New
Ametek or is serving at the request of New Ametek as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other entity against any liability asserted against him and incurred by him in
any such capacity, or arising out of his status as such, to the fullest extent
permitted under applicable law as then in effect. In addition, the New Ametek
Certificate and By-Laws provide that New Ametek may create a trust fund, grant
a security interest and/or use other means (including, without limitation,
letters of credit), as well as enter into contracts providing for
indemnification to the full extent authorized or permitted by law to ensure
the payment of such amounts as may become necessary to effect indemnification
as provided therein, or elsewhere.
 
  Moreover, the New Ametek Certificate further provides that no director of
New Ametek shall be personally liable to New Ametek or its stockholders for or
with respect to any acts or omissions in the performance of his or her duties
as a director of New Ametek, except a director shall be liable to the extent
provided by applicable law (i) for any breach of the director's duty of
loyalty to New Ametek or its stockholders; (ii) for acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of
law; (iii) for liability under Section 174 of the DGCL (involving certain
unlawful dividends or stock repurchases); or (iv) any transaction from which
the director derived an improper personal benefit. This provision does not
limit or eliminate the rights of New Ametek or any stockholder to seek non-
monetary relief such as an injunction or rescission in the event of a breach
of a director's duty of care.
 
  New Ametek maintains officer's and director's liability insurance with
policy limits of $50,000,000 insuring its officers and directors against
certain liabilities and expenses incurred by them in their capacities as such,
and insuring New Ametek under certain circumstances, in the event that
indemnification payments are made by New Ametek to such officers and
directors.
 
  Pursuant to Indemnity Agreements between New Ametek and its directors and
officers, New Ametek has agreed to indemnify such directors and officers to
the fullest extent permitted by Delaware law, as the same may be amended from
time to time.

                                    PART II
 
                    INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Section 145 of the DGCL empowers a corporation, subject to certain
limitations, to indemnify its directors and officers against expenses
(including attorneys' fees, judgments, fines and certain settlements) actually
and reasonably incurred by them in connection with any suit or proceeding to
which they are a party so long as they acted in good faith and in a manner
reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, so long
as they had no reasonable cause to believe their conduct was unlawful.
 
  The Culligan Certificate provides that Culligan will indemnify the directors
and officers of Culligan to the fullest extent permitted by Delaware law.
 
  In addition, the Culligan By-Laws provide that Culligan will indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceedings, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of Culligan), by reason of the fact that he is or was a director or
officer of Culligan, or is or was serving at the request of Culligan as a
director, officer, employee or agent of another corporation, partnership,
joint venture, trust, employee benefit plan or other enterprise, against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of Culligan
and, with respect to any criminal action or proceeding, had no reasonable
cause to believe his conduct was unlawful. The termination of any action, suit
or proceeding by judgment, order, settlement, conviction or upon plea of nolo
contendere or its equivalent, shall not, of itself, create a presumption that
the person did not act in good faith and in a manner which he reasonably
believed to be in or not opposed to the best interests of Culligan and, with
respect to any criminal action or proceeding, had reasonable cause to believe
that his conduct was unlawful.
 
  The Culligan By-Laws provide that Culligan will indemnify any person who was
or is a party or is threatened to be made a party to any threatened, pending
or completed action or suit by or in the right of Culligan to procure a
judgment in its favor by reason of the fact that he is or was a director or
officer of Culligan or is or was serving at the request of Culligan as a
director, officer, employee or agent of another corporation, partnership,
joint venture, trust, employee benefit plan or other enterprise against
expenses (including attorneys' fees) actually and reasonably incurred by him
in connection with the defense or settlement of such action or suit if he
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of Culligan; except that no indemnification
shall be made in respect of any claim, issue or matter as to which such person
shall have been adjudged to be liable to Culligan unless and only to the
extent that the Court of Chancery of the State of Delaware or the court in
which action or suit was brought shall determine upon application that,
despite the adjudication of liability but in view of all the circumstances of
the case, such person is fairly and reasonably entitled to indemnity for such
expenses which the Court of Chancery of the State of Delaware or such other
court shall deem proper.
 
  The Culligan By-Laws provide that any indemnification under the above two
paragraphs (unless ordered by a court) will be made by Culligan only as
authorized in the specific case upon a determination that indemnification of
the director, officer, employee or agent is proper in the circumstances
because he has met the applicable standard of conduct set forth in the above
two paragraphs. Such determination shall be made (1) by the Culligan Board by
a majority vote of a quorum consisting of directors who were not parties to
such action, suit or proceeding, even though less than a quorum, or (2) if
there are such directors or if such directors so direct, by independent legal
counsel in a written opinion, or (3) by the stockholders of Culligan.
 
                                     II-1
<PAGE>
 
  The Culligan By-Laws provide that to the extent that a director or officer
of Culligan has been successful on the merits or otherwise in defense of any
action, suit or proceeding referred to above, or in defense of any claim,
issue or matter therein, Culligan will indemnify him against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection therewith.
 
  The Culligan By-Laws further provide that expenses incurred by a director or
officer in defending or investigating a threatened or pending action, suit or
proceeding will be paid by Culligan in advance of the final disposition of
such action, suit or proceeding upon receipt of an undertaking by or on behalf
of the director or officer to repay such amount if it shall ultimately be
determined that he is not entitled to be indemnified by Culligan as authorized
in the Culligan By-Laws. Such expenses incurred by other employees and agents
may be so paid on such terms and conditions, if any, as Culligan Board deems
appropriate.
 
  The Culligan By-Laws provide that the indemnification and advancement of
expenses provided by, or granted pursuant to, the Culligan By-Laws shall not
be deemed exclusive of any other rights to which those seeking indemnification
or advancement of expenses may be entitled under any by-law, agreement, vote
of stockholders or disinterested directors or otherwise, both as to action in
his official capacity and as to action in another capacity while holding such
office.
 
  As permitted by the DGCL, the Culligan Certificate contains a provision
limiting the liability of directors for breach of fiduciary duty to Culligan
or its stockholders except for liability (i) for breach of the director's duty
of loyalty to Culligan or its stockholders, (ii) for acts or omissions not in
good faith or which involve intentional misconduct or knowing violation of
law, (iii) under Section 174 of the DGCL or (iv) for any transaction from
which the director derived an improper personal benefit.
 
  Culligan carries policies of insurance which cover the individual directors
and officers of Culligan and its subsidiaries for legal liability and which
would pay on behalf of Culligan for expenses of indemnification of directors
and officers in accordance with the Culligan Certificate and Culligan By-Laws.
 
  Culligan has entered into indemnification agreements with each of Culligan's
directors and officers. The indemnification agreements require, among other
things, Culligan to indemnify the officers and directors to the fullest extent
permitted by law, and to advance such directors and officers all related
expenses, subject to reimbursement, if it is subsequently determined that
indemnification is not permitted. Culligan will also indemnify and advance all
expenses incurred by such directors and officers seeking to enforce their
rights under the indemnification agreements, and cover directors and officers
under Culligan directors' and officers' liability insurance. Although such
indemnification agreements offer substantially the same scope of coverage
afforded by the Culligan Certificate and Culligan By-Laws, they provide
greater assurance to directors and officers that indemnification will be
available because, as a contract, it cannot be modified unilaterally in the
future by the Culligan Board or by Culligan stockholders to eliminate the
rights provided therein.
 
ITEM 21. EXHIBITS AND FINANCIAL STATEMENT SCHEDULES.
   
  A list of exhibits included as part of this Registration Statement is set
forth in the Exhibit Index which immediately precedes such exhibits and is
hereby incorporated by reference herein.     
 
ITEM 22. UNDERTAKINGS.
 
  Culligan (hereinafter the "Registrant") hereby undertakes as follows:
 
    (1) to file, during any period in which offers or sales are being made, a
  post-effective amendment to this Registration Statement:
 
      (i) to include any prospectus required by Section 10(a)(3) of the
    Securities Act;
 
      (ii) to reflect in the prospectus any facts or events arising after
    the effective date of the Registration Statement (or the most recent
    post-effective amendment thereof) which, individually or in
 
                                     II-2
<PAGE>
 
    the aggregate, represent a fundamental change in the information set
    forth in the Registration Statement. Notwithstanding the foregoing, any
    increase or decrease in volume of securities offered (if the total
    dollar value of securities offered would not exceed that which was
    registered) and any deviation from the low or high end of the estimated
    maximum offering range may be reflected in the form of prospectus filed
    with the Commission pursuant to Rule 424(b) if, in the aggregate, the
    changes in volume and price represent no more than a 20% change in the
    maximum aggregate offering price set forth in the "Calculation of
    Registration Fee" table in the effective Registration Statement;
 
    (iii) to include any material information with respect to the plan of
    distribution not previously disclosed in the Registration Statement or
    any material change to such information in the Registration Statement;
 
    provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
  registration statement is on Form S-3 or Form S-8 or Form F-3, and the
  information required to be included in a post-effective amendment by those
  paragraphs is contained in periodic reports filed with or furnished to the
  Commission by the Registrant pursuant to Section 13 or Section 15(d) of the
  Exchange Act that are incorporated by reference in the Registration
  Statement;
 
    (2) that, for the purpose of determining any liability under the
  Securities Act, each such post-effective amendment shall be deemed to be a
  new registration statement relating to the securities offered therein, and
  the offering of such securities at that time shall be deemed to be the
  initial bona fide offering thereof;
 
    (3) to remove from registration by means of a post-effective amendment
  any of the securities being registered which remain unsold at the
  termination of the offering;
 
    (4) that for purposes of determining any liability under the Securities
  Act, each filing of the Registrant's annual report pursuant to Section
  13(a) or Section 15(d) of the Exchange Act (and, where applicable, each
  filing of an employee benefit plan's annual report pursuant to Section
  15(d) of the Exchange Act) that is incorporated by reference in the
  Registration Statement shall be deemed to be a new registration statement
  relating to the securities offered therein, and the offering of such
  securities at that time shall be deemed to be the initial bona fide
  offering thereof;
 
    (5) that prior to any public reoffering of the securities registered
  hereunder through use of a prospectus which is a part of this Registration
  Statement, by any person or party who is deemed to be an underwriter with
  the meaning of Rule 145(c), such reoffering prospectus will contain the
  information called for by the applicable registration form with respect to
  reofferings by persons who may be deemed underwriters, in addition to the
  information called for by the other items of the applicable form.
 
    (6) that every prospectus (i) that is filed pursuant to paragraph (5)
  immediately preceding, or (ii) that purports to meet the requirements of
  Section 10(a)(3) of the Securities Act and is used in connection with an
  offering of securities subject to Rule 415, will be filed as a part of an
  amendment to this Registration Statement and will not be used until such
  amendment is effective, and that, for purposes of determining any liability
  under the Securities Act, each such post-effective amendment shall be
  deemed to be a new registration statement relating to the securities
  offering therein, and the offering of such securities at that time shall be
  deemed to be the initial bona fide offering thereof;
 
    (7) insofar as indemnification for liabilities arising under the
  Securities Act may be permitted to directors, officers and controlling
  persons of the Registrant pursuant to the provisions referred to Item 20
  above, or otherwise, the Registrant has been advised that in the opinion of
  the Commission such indemnification is against public policy as expressed
  in the Securities Act and is, therefore, unenforceable. In the event that a
  claim for indemnification against such liabilities (other than the payment
  by the Registrant of expenses incurred or paid by a director, officer or
  controlling persons of the Registrant in the successful defense of any
  action, suit or proceeding) is asserted by such director, officer or
  controlling person in connection with the securities being registered, the
  Registrant will, unless in the opinion of its counsel the matter has been
  settled by controlling precedent, submit to a court of appropriate
  jurisdiction the question of whether such indemnification by it is against
  public policy as expressed in the Securities Act and will be governed by
  the final adjudication of such issue;
 
                                     II-3
<PAGE>
 
    (8) to respond to requests for information that is incorporated by
  reference in the Registration Statement pursuant to Item 4, 10(b), 11 or 13
  of Form S-4, within one business day of receipt of such request and to send
  the incorporated documents by first class mail or other equally prompt
  means. This includes information contained in documents filed subsequent to
  the effective date of this Registration Statement through the date of
  responding to the request; and
 
    (9) to supply by means of a post-effective amendment all information
  concerning a transaction, and the company being acquired involved therein,
  that was not the subject of and included in the Registration Statement when
  it became effective.

interest to which such holder would otherwise be entitled. Any person holding
more than one certificate representing Ametek Common Stock ("Ametek
Certificate") must surrender all Ametek Certificates registered in the name of
such person in order to receive a certificate representing Culligan Common

such holder. The Exchange Agent will hold all such dividends and other

  The undersigned surrenders herewith for cancellation the Ametek

product of any fractional interest multiplied by [    ], in lieu of any
fractional share of Culligan Common Stock.
 
  The undersigned hereby represents and warrants that the undersigned has full
power and authority to deliver for surrender and cancellation the above-
described Ametek Certificate(s) delivered and that all rights represented by
such Certificate(s) are free and clear of all liens, restrictions, charges and

surrender of the Ametek Certificate(s) delivered herewith. All authority herein
conferred shall survive the death or incapacity of the undersigned and all

personal representatives, successors and assigns of the undersigned. Submission
of the Ametek Certificate(s) delivered herewith for surrender and cancellation

  All questions as to the proper completion and execution of this Letter of
Transmittal, the form, validity or eligibility for surrender of each Ametek
Certificate and the adequacy of any other documentation submitted in connection
with this Letter of Transmittal will be determined by Culligan (or by the
Exchange Agent if delegated such authority). Any such determination shall be
final and binding. No surrender of Ametek Certificate(s) shall be deemed to
have been effectively made until all defects and irregularities shall have been
cured or waived.

surrenders of Ametek Certificate(s) that are defective or irregular in any
respect and may request from persons making such surrenders such additional
documents as the Exchange Agent or Culligan deem appropriate to cure any such

irregularities, which have not been waived, have been cured.

<PAGE>
 
9.LOST CERTIFICATES
 
  In the event that any Ametek stockholder is unable to deliver to the Exchange
Agent the Ametek Certificate(s) representing his, her or its shares of Ametek
Common Stock due to the loss or destruction of such Certificate(s), such fact
should be indicated on the face of this Letter of Transmittal. In such event,
the Exchange Agent will forward additional documentation which such shareholder
must complete in order to effectively surrender such lost or destroyed Ametek
Certificate(s). There may be a fee in respect of lost or destroyed Ametek
Certificates, but surrenders hereunder will be processed only after such
documentation has been submitted to and approved by the Exchange Agent.
 
10.SUBSTITUTE FORM W-9
 
  The registered holder of surrendered Ametek Certificates (or other payee) is
required, unless an exemption applies, to provide the Exchange Agent with a
correct Taxpayer Identification Number ("TIN"), generally the holder's social
security or federal employer identification number, and with certain other
information, on Substitute Form W-9 (Box D), which is provided under "Important
Tax Information" below, and to certify under penalties of perjury, that such
number is correct and that the holder (or other payee) is not subject to backup
withholding. If a holder is subject to backup withholding, he or she must cross
out item (2) of the Certification Box on Substitute Form W-9 before signing
such Form. Failure to furnish the correct TIN on the Substitute Form W-9 may
subject the holder (or other payee) to a $50 penalty imposed by the Internal
Revenue Service and payments of cash to the holder (or other payee) may be
subject to backup withholding of 31%. If the holder has not been issued a TIN
and has applied for a number or intends to apply for a number in the near
future, he or she should write "Applied For" in the space provided for on the
TIN in Part I, sign and date the Substitute Form W-9 and sign and date the
Certificate of Awaiting Taxpayer Identification Number. If "Applied For" is
written in Part I and the Exchange Agent is not provided with a TIN by the time
of payment, the Exchange Agent will withhold 31% of all payments of cash
thereafter until a TIN is provided to the Exchange Agent.
 
11.HOLDERS WHO ARE NOMINEES
 
  Any record holder of Ametek Certificate(s) may submit two or more Letters of
Transmittal, each covering a portion of the shares of Ametek Common Stock
represented thereby, provided that such record holder submits with such Letters
of Transmittal a certificate satisfactory to the Exchange Agent to the effect
that such record holder holds such shares as nominee for more than one owner.
 
12.INADEQUATE SPACE
 
  If the space provided in Box A is inadequate, the Ametek Certificate numbers
and the number of shares of Ametek Common Stock represented thereby should be
listed on a separate signed schedule attached hereto.
 
13.MISCELLANEOUS.
 
  The terms and conditions of the Merger Agreement are incorporated herein by
reference in their entirety and shall be deemed to form a part of the terms and
conditions of this Letter of Transmittal.
 
14.INQUIRIES.
 
  If you have any questions or need assistance relating to the Letter of
Transmittal, please contact the Exchange Agent at: (800) [    ]. Additional
copies of this Letter of Transmittal may be obtained from the Exchange Agent.

<PAGE>
 
                           IMPORTANT TAX INFORMATION
 
 
  Under federal income tax law, a stockholder surrendering Ametek Certificates
must, unless an exemption applies, provide the Exchange Agent (as payer) with
his correct TIN on Substitute Form W-9 included in this Letter of Transmittal.
If the stockholder is an individual, his TIN is his social security number. If
the correct TIN is not provided, the stockholder may be subject to a $50
penalty imposed by the Internal Revenue Service and payments of cash to the
stockholder (or other payee) may be subject to backup withholding of 31%.
 
  Certain stockholders (including, among others, all corporations and certain
foreign individuals and entities) are not subject to backup withholding. In
order for an exempt foreign stockholder to avoid backup withholding, that
person should complete, sign and submit a Form W-8, Certificate of Foreign
Status, signed under penalties of perjury, attesting to his exempt status. A
Form W-8 can be obtained from the Exchange Agent. Exempt stockholders, other
than foreign stockholders, should furnish their TIN, write "Exempt" on the face
of the Substitute Form W-9 and sign, date and return the Substitute Form W-9 to
the Exchange Agent. See the enclosed "Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9" for additional instructions.
 
  If backup withholding applies, the Exchange Agent is required to withhold 31%
of any payment made to payee. Backup withholding is not an additional tax.
Rather, the federal income tax liability of persons subject to backup
withholding will be reduced by the amount of tax withheld. If backup
withholding results in an overpayment of taxes, a refund may be obtained from
the Internal Revenue Service.
 
PURPOSE OF SUBSTITUTE FORM W-9
 
  To prevent backup withholding on payments that are made to a stockholder, the
stockholder is required to notify the Exchange Agent of his correct TIN (or the
TIN of any other payee) by completing the Substitute Form W-9 included in this
Letter of Transmittal certifying (1) that the TIN provided on the Substitute
Form W-9 is correct (or that such stockholder is awaiting a TIN), and that (2)
the stockholder is not subject to backup withholding because (i) the
stockholder has not been notified by the Internal Revenue Service that the
stockholder is subject to backup withholding as a result of a failure to report
all interest and dividends or (ii) the Internal Revenue Service has notified
the stockholder that the stockholder is no longer subject to backup
withholding.
 
WHAT NUMBER TO GIVE THE EXCHANGE AGENT
 
  The stockholder is required to give the Exchange Agent the TIN, generally the
social security number or employer identification number, of the record owner
of the Ametek Certificates. If the Ametek Certificates are in more than one
name or are not in the name of the actual owner, consult the enclosed
Guidelines for Certification of Taxpayer Identification Number on Substitute
Form W-9 for additional guidance on which number to report. If the stockholder
has not been issued a TIN and has applied for a number or intends to apply for
a number in the near future, he or she should write "Applied For" in the space
provided for the TIN in Part I, sign and date the Substitute Form W-9 and sign
and date the Certificate of Awaiting Taxpayer Identification Number, which
appears in a separate box below the Substitute Form W-9. If "Applied For" is
written in Part I and the Exchange Agent is not provided with a TIN by the time
of payment, the Exchange Agent will withhold 31% of all cash payments until a
TIN is provided to the Exchange Agent.

                        Substitute Form W-9 and complete as instructed
                        therein.

                        CERTIFICATION--Under penalties of perjury, I certify
                        that:
                        (1) The number shown on this form is my correct tax-
                            payer identification number (or I am waiting for
                            a number to be issued to me), and
                        (2) I am not subject to backup withholding because
                            either (a) I am exempt from backup withholding,
                            or (b) I have not been notified by the Internal
                            Revenue Service ("IRS") that I am subject to
                            backup withholding as a result of a failure to
                            report all interest or dividends, or (c) the IRS
                            has notified me that I am no longer subject to
                            backup withholding.

                          (2) above if you have been notified by the IRS that
                          you are subject to backup withholding because of
                          underreporting interest or dividends on your tax
                          return. However, if after being notified by the IRS
                          that you were subject to backup withholding you re-
                          ceived another notification from the IRS that you
                          are no longer subject to backup withholding, do not
                          cross out item (2). (Also see instructions in the
                          enclosed Guidelines.)
