(the "Offer Price"), upon the terms and subject to the conditions set forth in
the Offer to Purchase dated March 3, 1998 (the "Offer to Purchase") and the

ARRANGEMENTS WITH THE PURCHASER, PCC OR THEIR AFFILIATES.
 
    MERGER AGREEMENT.
 
    THE OFFER.  The Merger Agreement provides that PCC will cause the Purchaser
to commence, and the Purchaser will commence, the Offer to purchase all of the
Shares for $15.25 per Share. The Merger Agreement specifies certain conditions
for the Offer, including, among other things, the Minimum Condition (as defined
below). Pursuant to the Merger Agreement, the Purchaser expressly reserves the
right to change or waive any such condition, to increase the Offer Price, and to
make any other changes in the terms and conditions of the Offer; provided
however, that without the prior written consent of the Company, the Purchaser
will not (i) decrease the Offer Price, (ii) change the Minimum Condition, (iii)
decrease the number of Shares sought pursuant to the Offer, (iv) impose
conditions in addition to the Offer Conditions (as defined below) or (v)
otherwise amend the Offer in any manner adverse to the Company's stockholders.
Notwithstanding the foregoing, the Purchaser may, without the Company's consent
(x) extend the Offer, if at the original Expiration Date (as defined in the
Offer) the Minimum Condition or any of the Offer Conditions have not been
satisfied or waived; (y) extend the Offer for any period required by any rule,
regulation, interpretation or position of the SEC; or (z) extend the Offer for
no more than ten (10) business days beyond the original Expiration Date in the
event that the Offer Conditions have been satisfied but less than ninety percent
(90%) of the Shares have been tendered pursuant to the Offer.
 
                                       1
<PAGE>
    THE MERGER.  The Merger Agreement provides that, on the terms and subject to
the conditions set forth in the Merger Agreement and in accordance with the
relevant provisions of the New York Business Corporation Law ("NYBCL"), as soon
as practicable following the satisfaction or waiver, if permissible, of the
conditions described below under "Conditions to the Merger," the Purchaser will
be merged with and into the Company (the "Merger") with the Company as the
surviving corporation in the Merger (the "Surviving Corporation"). The Merger
will become effective at the time of filing of a certificate of merger, as
required by the NYBCL (the "Effective Time"). At the Effective Time, each Share
issued and outstanding immediately prior to the Effective Time (other than
Shares owned by PCC, by the Purchaser or by any other direct or indirect
subsidiary of PCC or of the Company, or held in the treasury of the Company, all
of which will be canceled without any conversion thereof and no payment or
distribution will be made with respect thereto) will be canceled and converted
automatically into the right to receive an amount equal to the Offer Price in
cash (the "Merger Consideration") net to the holder, without any interest
thereon.
 
    STOCKHOLDERS MEETING.  The Merger Agreement provides that the Company will,
if required by applicable law, call and hold a special meeting of its
stockholders as soon as practicable following the consummation of the Offer for
the purpose of approving the Merger and will prepare and file with the SEC under
the Securities Exchange Act of 1934, as amended (the "Exchange Act") a proxy
statement with respect to the meeting of stockholders described above (the
"Proxy Statement"). The Company has agreed in the Merger Agreement to use its
best efforts to respond to any comments of the SEC or its staff and to cause the
Proxy Statement to be mailed to the Company's stockholders as promptly as
practicable after responding to all such comments to the satisfaction of the
staff, and to keep PCC informed of all its correspondence with the SEC with
respect to the Proxy Statement. Pursuant to the Merger Agreement, the Company,
through its Board of Directors, will recommend in the Proxy Statement that the
Merger Agreement be approved.
 
    Notwithstanding any other provision in the Agreement, if PCC, the Purchaser,
or any affiliate of either of them beneficially owns at least 90% of the
outstanding Shares, the parties shall take all necessary and appropriate action
to cause the Merger to become effective as soon as practicable after the
Expiration Date, but in no event later than ten business days thereafter,
without a meeting of the stockholders of the Company in accordance with Section
905 of the NYBCL.
 
    STOCK OPTIONS AND WARRANTS.  The Merger Agreement provides that the Company
will use its best efforts to enter into an agreement with each holder of an
employee or director stock option or warrant to purchase Shares (in each case,
an "Option" or "Warrant") that provides that, immediately after the date on
which the Purchaser will have accepted for payment all Shares validly tendered
and not withdrawn prior to the Expiration Date with respect to the Offer (the
"Tender Offer Acceptance Date"), each Option or Warrant that is then
outstanding, whether or not then exercisable or vested, will be canceled by the
Company, and each holder of a canceled Option will be entitled to receive from
the Purchaser, at the same time as payment for Shares is made by the Purchaser
in connection with the Offer, in consideration for the cancellation of such
Option or Warrant, an amount in cash equal to the product of (i) the number of
Shares previously subject to such Option or Warrant, whether or not then
exercisable or vested, and (ii) the excess, if any, of the Offer Price over the
exercise price per Share previously applicable to such Option or Warrant,
reduced by any applicable withholding. Alternatively, the Company may advance
funds to one or more Option holders to permit such holders to exercise their
Options (whether or not then exercisable or vested) and tender the Shares so
acquired in the Offer.
 
    REPRESENTATIONS AND WARRANTIES.  The Merger Agreement contains
representations and warranties by the Company, relating to, among other things,
(i) the organization of the Company and other corporate matters, (ii) the
capital structure of the Company, (iii) the authorization, execution, delivery
and consummation of the transactions contemplated by the Merger Agreement, (iv)
consents and approvals, (v) documents filed by the Company with the SEC and the
accuracy of the information contained therein,
 
                                       2
<PAGE>
(vi) the accuracy of the information contained in documents filed with the SEC
in connection with the Offer and the Merger, (vii) litigation, (viii)
environmental matters, (ix) absence of material changes, and (x) taxes.
 
    In addition, the Merger Agreement contains representations and warranties by
PCC, relating to, among other things, the organization and ownership of PCC and
the Purchaser, their authority to enter into the Merger Agreement and their
financial capability to purchase the Shares pursuant to the Offer.
 
    CONDUCT OF BUSINESS PENDING THE MERGER.  In the Merger Agreement, the
Company has agreed that, prior to the Effective Time, except as otherwise
provided in the Merger Agreement or with the prior written consent of PCC, the
Company (a) will use its best efforts to (i) keep the business and organization
of the Company intact, and (ii) carry on the business of the Company in its
usual manner; (b) will not declare, pay, or set aside for payment any dividend
or other distribution of money or property in respect of its capital stock; (c)

rights to subscribe to, any shares of its capital stock or subdivide or in any
way reclassify any shares of its capital stock, or repurchase, reacquire,
cancel, or redeem any such shares; (d) will use its best efforts to ensure that
(A) it preserves and maintains in the ordinary course of business its assets,

all material respects with all applicable laws, and (D) it will maintain its
insurance; (e) will not incur additional debt, incur or increase any obligation
or liability, except in the ordinary and usual course of its business; and (f)
will not make any payment to discharge or satisfy any lien or encumbrance or pay
any obligation or liability (fixed or contingent) other than current liabilities
or payments under its revolving credit facility made in the ordinary course of
business and consistent with past practices.
 
    The Company has further agreed that, until the Effective Time, it will not,
without the prior consent of PCC: (a) acquire any assets other than in the
ordinary and usual course of its business and consistent with past practices;
(b) purchase or otherwise acquire, or agree to purchase or otherwise acquire,
any debt or equity securities of any person other than equity securities issued
by a money market fund registered as an investment company under the Investment
Company Act of 1940; (c) enter into any transaction or contract or make any
commitment to do the same, except in the ordinary and usual course of business
and not requiring the payment in any case of an amount in excess of $50,000
annually; (d) increase the wages, salaries, compensation, pension, or other
benefits payable, or to become payable by it, to any of its officers, employees,

or except as expressly contemplated by or otherwise in the ordinary and usual
course of its business; (e) implement or agree to any implementation of or

policies or practices. In addition, the Company (a) will, when the consent of
any third party to the transactions contemplated by the Merger Agreement is
required under the terms of any contract to which it is a party or by which it
is bound, use its best efforts to obtain such consent; (b) will maintain its
books and records in accordance with past practice and in accordance with
generally accepted accounting principles; (c) will pay and discharge all taxes,
assessments, governmental charges and levies imposed upon it, its income or
profits, or upon any property belonging to it, and in all cases before the date
on which penalties attach thereto; (d) will not amend its Certificate of
Incorporation or Bylaws; and (e) will not transafer any shares of treasury stock
or authorized and unissued stock to its Deferred Compensation Plan Trust on
account of bonus amounts deferred under its Deferred Compensation Plan relating

    PROHIBITION ON SOLICITATION.  Pursuant to the Merger Agreement, the Company
has agreed that the Company and its officers, directors, employees,
representatives and agents will cease any discussions or
 
                                       3
<PAGE>
negotiations with any parties with respect to any Takeover Proposal (as defined
below); and, unless the Merger Agreement has been terminated in accordance with
its terms and so long as neither PCC nor the Purchaser is in material violation
of the Merger Agreement, the Company will not authorize or permit any officer,
director or employee of, or any investment banker, financial advisor, attorney,
accountant or other representative retained by the Company or any of its
subsidiaries to (a) solicit, initiate, encourage or take any other action to
facilitate any inquiries or the making of any proposal that constitutes, or may
reasonably be expected to lead to, any Takeover Proposal or (b) participate in
any discussions or negotiate regarding any Takeover Proposal.
 
    The Merger Agreement provides that, notwithstanding the foregoing, if at any
time prior to the Effective Time, the Board of Directors of the Company
determines in good faith, after consultation with counsel, that it is necessary
to do so in order to comply with its fiduciary duties to the Company's
stockholders under applicable law, the Company may, in response to an
unsolicited Takeover Proposal, (a) furnish information with respect to the
Company to any person pursuant to a confidentiality agreement in substantially
the same form as that entered into between the Company and PCC, and (b)
participate in negotiations regarding such Takeover Proposal.
 
    The Merger Agreement provides further that, unless the Merger Agreement has
been terminated in accordance with its terms and so long as neither PCC nor the
Purchaser is in material violation of the Merger Agreement, neither the Board of
Directors of the Company nor any committee thereof will (a) withdraw or modify,
or propose to withdraw or modify, in a manner adverse to PCC, the approval or
recommendation by such Board of Directors or such committee of the Offer, the
Merger Agreement or the Merger, (b) approve or recommend, or propose to approve
or recommend, any Takeover Proposal or (c) cause the Company to enter into any
agreement with respect to any Takeover Proposal.
 
    Notwithstanding the foregoing, in the event that prior to the Effective Time
the Board of Directors of the Company determines in good faith, after
consultation with counsel, that it is necessary to do so in order to comply with
its fiduciary duties to the Company's stockholders under applicable law, the
Merger Agreement provides that the Board of Directors of the Company may
withdraw or modify its approval or recommendation of the Offer, the Merger
Agreement and the Merger, approve or recommend a Superior Proposal (as defined
below), or cause the Company to enter into an agreement with respect to a
Superior Proposal, but in each case only at a time that is after the second
business day following PCC's receipt of written notice advising PCC that the
Board of Directors of the Company has received a Superior Proposal, specifying
the material terms and conditions of such Superior Proposal and identifying the
person making such Superior Proposal, and that the Company has elected to
terminate the Agreement pursuant to the termination provisions described below.
 
    Pursuant to the Merger Agreement, and in addition to the obligations of the
Company described above, the Company has agreed that (a) it will advise PCC
within 48 hours after receiving any request for information or any Takeover
Proposal, or any inquiry with respect to or which could lead to any Takeover
Proposal, the material terms and conditions of such request, Takeover Proposal
or inquiry and the identity of the person making such request, Takeover Proposal
or inquiry; and (b) it will keep PCC fully informed of the status and details
(including amendments or proposed amendments) of any such request, Takeover
Proposal or inquiry.
 
    The Merger Agreement does not prohibit the Company from making any
disclosure to the Company's stockholders if, in the opinion of the Board of
Directors of the Company, after consultation with counsel, failure to disclose
would be inconsistent with its fiduciary duties to the Company's stockholders
under applicable law, except that neither the Company nor its Board of Directors
nor any committee thereof may (other than as described above) withdraw or
modify, or propose to withdraw or modify, its position with respect to the Offer
or the Merger or approve or recommend, or propose to approve or recommend, a
Takeover Proposal.
 
                                       4
<PAGE>
    The term "Takeover Proposal" means any inquiry, proposal or offer from any
person relating to any direct or indirect acquisition or purchase of a
substantial amount of assets of the Company or of over 20% of any class of
equity securities of the Company, or any tender offer or exchange offer that if
consummated would result in any person beneficially owning 20% or more of any
class of equity securities of the Company, any merger, consolidation, business
combination, sale of substantially all the assets, recapitalization,
liquidation, dissolution (other than the transactions contemplated by the Merger
Agreement), or any other transactions the consummation of which could reasonably
be expected to impede, interfere with, prevent or materially delay the Offer or
the Merger or which would reasonably be expected to dilute materially the
benefits to PCC of the transactions contemplated by the Merger Agreement. The
term "Superior Proposal" means any bona fide Takeover Proposal to acquire,
directly or indirectly, for consideration consisting of cash and/or securities,
more than 50% of the shares of Common Stock of the Company then outstanding or
all or substantially all the assets of the Company and otherwise on terms which
the Board of Directors of the Company determines in its good faith judgment
(after consultation with The Nassau Group, Inc. or another financial advisor of
nationally recognized reputation) to be more favorable to the Company's
stockholders than the Offer and the Merger.
 
    ACCESS.  Pursuant to the Merger Agreement, from the date of the Merger
Agreement to the closing date for the Merger, the Company will provide, and
cause each subsidiary to provide, to PCC and its authorized agents, access to
their respective physical assets, facilities, financial information, production
records, contracts and other corporate records and documents during normal
working hours, and PCC will be allowed to meet with their respective management
personnel, employees, and any outside consultants, including auditors and
accountants, investment and other bankers, tax and financial advisors, and
environmental consultants.
 
    DIRECTORS.  The Merger Agreement provides that, upon the Purchaser's
acceptance for payment and payment for Shares pursuant to the Offer, the
Purchaser will be entitled to designate a number of directors (rounded up to the
nearest whole number) on the Company's Board of Directors that is equal to the
product of the total number of directors on the Company's Board multiplied by
the percentage that the aggregate number of Shares beneficially owned by
Purchaser and its affiliates bears to the number of Shares outstanding. The
Company will promptly, at the request of PCC, either increase the size of the
Company's Board of Directors and/or obtain the resignations of such number of
its current directors as is necessary to enable the Purchaser's designees to be
elected to the Company's Board of Directors as provided above.
 
    CONDITIONS TO THE OFFER.  Notwithstanding any other provision of the Offer,
the Purchaser shall not be required to accept for payment or pay for any
tendered Shares unless (i) Shares that constitute at least two thirds of the
then outstanding Shares (on a fully diluted basis) have been validly tendered
and not withdrawn (the "Minimum Condition"); and (ii) any applicable waiting
period under the Hart Scott Rodino Antitrust Improvements Act ("HSR Act") shall
have expired or been terminated. In addition, the Purchaser may terminate or
amend the Offer and postpone the acceptance for payment of and payment for
Shares tendered if, at any time on or after the date of the Merger Agreement and
prior to the acceptance for payment of Shares, any of the following conditions
(the "Offer Conditions") shall exist:
 
    (a) there shall have been issued and shall remain in effect any injunction,
       order or decree by any court or governmental, administrative or
       regulatory authority or agency, domestic or foreign, which (i) restrains
       or prohibits the making of the Offer or the consummation of the Merger,
       (ii) prohibits or limits ownership or operation by the Company, PCC or
       the Purchaser of all or any material portion of the business or assets of
       the Company, or PCC and its subsidiaries, taken as a whole, or compels
       the Company, PCC or any of its subsidiaries to dispose of or hold
       separate all or any material portion of the business or assets of the
       Company, or PCC and its subsidiaries, taken as a whole, in each case as a
       result of the Offer or the Merger; (iii) imposes material limitations on
       the ability of PCC or the Purchaser to exercise effectively full rights
       of ownership
 
                                       5
<PAGE>
       of any Shares, including, without limitation, the right to vote any
       Shares acquired by the Purchaser pursuant to the Offer, or otherwise on
       all matters properly presented to the Company's stockholders, including,
       without limitation, the approval and adoption of the Merger Agreement and
       the Merger; or (iv) requires divestiture by PCC or the Purchaser of any
       material portion of the Shares;
 
    (b) there shall have been any action taken, or any statute, rule,

       legislative body, court, government or governmental, administrative or
       regulatory authority or agency, domestic or foreign (other than, in the
       case of both (i) and (ii), the application of the waiting period
       provisions of the HSR Act to the Offer or the Merger), which results in
       any of the consequences referred to in clauses (i) through (iv) of
       paragraph (a) above;
 
    (c) there shall have occurred and be continuing (i) a 25 percent or greater
       decline in the Dow Jones Average of Industrial Stocks and the Standard &
       Poor's 500 Index since the date of the Merger Agreement, (ii) any general
       suspension of trading in, or limitation on prices for, securities on the
       New York Stock Exchange or in the over-the-counter market, (iii) a
       declaration of a banking moratorium or any suspension of payments in
       respect of banks in the United States, (iv) any limitation (whether or
       not mandatory) by any governmental authority on the general extension of
       credit by banks or other financial institutions, or (v) in the case of
       any of the foregoing existing at the time of the commencement of the
       Offer, in the reasonable judgment of PCC, a material worsening thereof;
 
    (d) the Company's Board of Directors or any committee thereof shall have
       withdrawn or modified in a manner adverse to PCC or the Purchaser its
       approval or recommendation of the Offer, the Merger or the Merger
       Agreement or shall have approved or recommended another merger,
       consolidation, business combination with, or acquisition of the Company
       or all or substantially all its assets or another tender offer or
       exchange offer for Shares, or shall have resolved to do any of the
       foregoing;
 
    (e) the Company shall have failed to perform in any material respect any of
       its material covenants in the Merger Agreement, where such failure either
       individually or in the aggregate would have a Combined Material Adverse
       Effect (as defined below);
 
    (f) the representations and warranties of the Company shall fail to be true
       and correct in all material respects on and as of the date made or,
       except as otherwise expressly contemplated, on and as of any subsequent
       date as if made at and as of such subsequent date, which failure either
       individually or in the aggregate would have a Combined Material Adverse
       Effect;
 
    (g) the Merger Agreement shall have been terminated in accordance with its
       terms;
 
    (h) the Purchaser and the Company shall have agreed that the Purchaser shall
       terminate the Offer or postpone the acceptance for payment of or payment
       for Shares thereunder; or
 
    (i) since December 31, 1997, except as (i) expressly contemplated by the
       Merger Agreement, (ii) disclosed in any of the Company's periodic reports
       to the SEC filed since such date and prior to the date of the Merger
       Agreement, or (iii) set forth in the Merger Agreement, there shall have
       occurred any event having, individually or in the aggregate, a change or
       effect that is materially adverse to the business, operations,
       properties, financial condition, assets or liabilities (including,
       without limitation, contingent liabilities) of the Company.
 
                                       6
<PAGE>
    The Merger Agreement provides that the foregoing conditions are for the sole
benefit of the Purchaser and PCC and may be asserted by the Purchaser or PCC
regardless of the circumstances giving rise to any such condition or may be
waived by the Purchaser or PCC in whole or in part at any time and from time to
time in its sole discretion. The failure by the Purchaser or PCC at any time to
exercise any of the foregoing rights shall not be deemed a waiver of any such
right; the waiver of any such right with respect to particular facts and other
circumstances shall not be deemed a waiver with respect to any other facts and
circumstances; and each such right shall be deemed an ongoing right that may be
asserted at any time and from time to time.
 
    A "Combined Material Adverse Effect," as used above, means any individual or
combination of events, changes or effects that are materially adverse to the

operations or results of operations of a party in excess of $500,000.
 
    CONDITIONS TO THE MERGER.  The respective obligations of each party to the
Merger Agreement to effect the Merger shall be subject to the satisfaction,
prior to the closing of the transactions contemplated by the Merger Agreement,
of the following conditions: (a) all required authorizations, consents, and
approvals of all governmental agencies and authorities shall have been obtained
and the waiting period under the HSR Act will have expired or been terminated
early; (b) if necessary under applicable law, the Merger shall have been
approved by at least 66 2/3 percent of the Shares of the Company; (c) no law,
statute, rule, regulation, decree, order, injunction or ruling by any

otherwise prevent the consummation of the Offer or the Merger; and (e) the
Purchaser shall have previously accepted for payment and paid for all Shares

    TERMINATION.  The Merger Agreement may be terminated at any time prior to
the closing date of the Merger (a) by mutual consent of PCC, Purchaser and the
Company; (b) by either PCC or the Company if (A) any governmental entity has
promulgated or issued a law, statute, rule, regulation, decree, order,
injunction, or ruling or taken any other action prohibiting, restraining,
enjoining, restricting or otherwise prohibiting the Offer or the Merger that has
become final and nonappealable, or if clearance under the HSR Act is not
received within 60 days of the filing of the premerger notification and report
form, or (B) the Offer is terminated or expires in accordance with its terms as
the result of failure of any of the Offer Conditions without Purchaser having
purchased any Shares pursuant to the Offer, except that this right to terminate
is not available to any party whose failure to perform any of its covenants or
agreements under the Merger Agreement results in the failure of any condition;
(c) by PCC, if not then in default, upon written notice to the Company if (A)
the Company breaches in any material respect any of its representations or
warranties or defaults in the observance or performance of any of its covenants
or agreements except for breaches or defaults which, individually or in the
aggregate, would not have a Combined Material Adverse Effect or materially
impair the ability of the parties to consummate the transactions contemplated by
the Merger Agreement, or (B) the Board of Directors of the Company or any
committee thereof has withdrawn or modified in a manner adverse to PCC or
Purchaser its approval or recommendation of the Offer or the Merger Agreement or
approved or recommended any Takeover Proposal, or (C) the Company has entered
into a definitive agreement with respect to any Superior Proposal; or (d) by the
Company, if not then in default, upon written notice to PCC if (A) PCC breaches
in any material respect any of its representations or warranties or defaults in
the observance or performance of any of its covenants or agreements, except for
breaches or defaults which, individually or in the aggregate, would not have a
Combined Material Adverse Effect or materially impair the ability of the parties
to consummate the transactions contemplated by the Merger Agreement, or (B) if
the Company determines after consultation with its counsel that it is necessary
to terminate the Merger or the Merger Agreement in order for its directors to
comply with their fiduciary duties under applicable law.
 
    In the event of the termination of the Merger Agreement, the Merger
Agreement shall forthwith become void and there shall be no liability on the
part of any party thereto except as described under "Fees
 
                                       7
<PAGE>
and Expenses" below; provided, however, that nothing in the Merger Agreement
will relieve any party from liability for any breach thereof before termination.
 
    FEES AND EXPENSES.  The Merger Agreement provides that, except as provided
in the following paragraph, all fees and expenses incurred in connection with
the Offer, the Merger, the Merger Agreement and the transactions contemplated
thereby will be paid by the party incurring such fees or expenses, whether or
not the Offer or the Merger is consummated.
 
    Under the Merger Agreement the Company will pay, or cause to be paid, to PCC
the sum of $2,000,000 upon demand if the Offer is not consummated due to the
Company's termination of the Merger Agreement in breach of the Merger Agreement.
Alternatively, if the Company determines in good faith, after consultation with
counsel, that it is necessary to terminate the Agreement in order for its
directors to comply with their fiduciary duties to the Company's stockholders
under applicable law, the Company will pay, or cause to be paid, to PCC the sum
of $3,000,000 (the "Termination Fee") upon demand if the Company (i) agrees to a
Superior Proposal within one year of the date of termination of the Agreement,
or (ii) within 270 days after termination of the Merger Agreement the Company
agrees to a Takeover Proposal. In addition, the Merger Agreement provides that
PCC will pay, or cause to be paid, to the Company the sum of $2,000,000 upon
demand if the Offer is not consummated due to PCC's termination of the Merger
Agreement in breach of the Merger Agreement.
 
    STANDSTILL.  The Merger Agreement provides that in the event that PCC does
not purchase Shares pursuant to the Offer, other than in circumstances involving
breach by the Company of the Merger Agreement, PCC and its affiliates shall not
directly or indirectly, for a period of 18 months from the date of the Merger
Agreement, unless the Company's Board of Directors approves such action, (i)
acquire or offer to acquire, seek, propose or agree to acquire, by means of a
purchase, agreement, business combination or in any other manner, beneficial
ownership of any securities or assets of the Company, including rights or
options to acquire such ownership, (ii) seek or propose to influence, change or
control the management or Board of Directors of the Company, or (iii) make any
public disclosure or announcement or submit a proposal for a transaction not in
the ordinary course of business, or take any action which could require the
other party to make any public disclosure, with respect to the matters set forth
in the Merger Agreement or in any way participate directly or indirectly in any
solicitation of proxies to vote, or influence any person or entity with respect
to the voting of, any voting securities of the Company. However, the foregoing
restrictions will not apply in the event that the Company receives a Takeover
Proposal from a party that is not affiliated with PCC.
 
    AMENDMENT.  The Merger Agreement may not be amended except by written
agreement of the parties thereto.

    STOCKHOLDER AGREEMENT.
 
    The members of the Company's Board of Directors (including Stephen V.
Ardia), as well as David M. Doin, George A. Earle III, George A. Vorsheim, Jr.,
Mark E. Alexander, Brian Buchinski, Kathleen A. Parry and Philip W. Welsh
(collectively, the "Selling Stockholders") are each parties to a Stockholder
Agreement dated February 24, 1998 with PCC and the Purchaser. The Stockholder
Agreement provides that each Selling Stockholder will tender his or her Shares
into the Offer so long as the per Share amount is not less than $15.25 in cash
(net to the seller). Additionally, each Selling Stockholder has agreed to sell,
and the Purchaser has agreed to purchase, their Shares at a price per share
equal to $15.25, or such higher price per share as may be offered by the
Purchaser in the Offer, provided that such obligations to purchase and sell are
both subject to (i) the Purchaser having accepted Shares for payment under the
Offer and the
 
                                       8
<PAGE>
Minimum Condition having been satisfied, and (ii) the expiration or termination
of any applicable waiting period under the HSR Act. Each Selling Stockholder has
also agreed not to transfer or agree to transfer their Shares, grant a proxy for
their Shares or enter into a voting agreement respecting them, or take any other
action that would in any way restrict, limit or interfere with the performance
of their obligations under the Stockholder Agreement or the transactions
contemplated thereby. The Stockholder Agreement terminates upon the earlier of
(i) the Merger Agreement being terminated by the Company, PCC or the Purchaser,
(ii) the purchase and sale of the Shares of the Selling Stockholders as
described above, or (iii) May 30, 1998. The foregoing summary of the Stockholder
Agreement is qualified in its entirety by the text of the Stockholder Agreement,
a copy of which has been filed with the Securities and Exchange Commission as
Exhibit 2 to this Schedule 14D-9.
 
    CONFIDENTIALITY AGREEMENT.
 
    On November 25, 1997, PCC entered into a Confidentiality Agreement, pursuant
to which PCC agreed to treat all information supplied by the Company or its
representatives as confidential and to use such information solely in connection
with the evaluation of a possible transaction with the Company. PCC further
agreed that, in the event that the transactions contemplated by the Merger
Agreement are not consummated, it will (i) return to the Company all information
furnished by the Company or its representatives, and (ii) refrain, for a period
of two years from the date of the Confidentiality Agreement, from soliciting or
hiring any employees of the Company while they are still employed by the
Company. The foregoing summary of the Confidentiality Agreement is qualified in
its entirety by the text of the Confidentiality Agreement, a copy of which has
been filed with the Securities and Exchange Commission as Exhibit 3 to this
Schedule 14D-9.

    Pursuant to the Merger Agreement, the Company has entered into an Employment
Agreement with Stephen V. Ardia, providing for Mr. Ardia to serve as the
Company's President for a term of one year beginning on the date that the Offer
is consummated, after which his employment may be continued on an at-will basis
by mutual agreement of the parties. The agreement provides that Mr. Ardia will

during the three month period January 1, 1999 through March 28, 1999. Mr. Ardia

programs, in accordance with the terms of those programs. Mr. Ardia may
terminate the agreement upon thirty days' written notice to the Company any time
after the first three months of its effectiveness.
 
    The Company also has a Change in Control Agreement with Mr. Ardia dated
January 5, 1998, providing for a payment to Mr. Ardia upon the occurrence of a
"Change of Control" (as defined in the agreement) equal to (i) the amount of his
annual base salary in effect on the date of the Change of Control, and (ii) an
amount equal to the sum of (A) the bonus payable to Mr. Ardia for the year
during which the Change of Control occurs, prorated through the date of the
Change of Control, plus (b) the average annual bonus paid to Mr. Ardia for the
two complete fiscal years that precede the fiscal year during which the Change
of Control occurs. In addition, the Company shall waive for twelve months
following his termination any required premium payment due from Mr. Ardia to
allow him to continue his coverage under the Company's group health plan. A
"Change of Control," as defined in the agreement, would occur upon the
Purchaser's acceptance for payment and payment for Shares pursuant to the Offer.

program provided will be consistent with bonus programs provided by PCC to
similarly situated employees. These employees will also be entitled to
participate in PCC's stock option and stock purchase programs, in accordance

    The agreements, which may be terminated by either party upon thirty days'
written notice, provide for a severance benefit equal to the following: (i) if
the employee is terminated before the first anniversary of the effective date of
the agreement, the remaining balance of the employee's base salary for the
portion of year from the date of termination until the first anniversary of the

she voluntarily resigns or withdraws from employment, is terminated for "cause"
(as defined in the agreement), terminates employment as a result of the
expiration of the term of the agreement, breaches certain confidentiality or
non-competition provisions in the agreement, or accepts reasonably comparable
employment with an affiliate of PCC.

ITEM 4.  THE SOLICITATION OR RECOMMENDATION
 
    A.  RECOMMENDATION OF THE BOARD OF DIRECTORS.
 
    THE BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND THE
TRANSACTIONS CONTEMPLATED THEREBY AND RECOMMENDS THAT THE STOCKHOLDERS OF THE
COMPANY TENDER THEIR SHARES PURSUANT TO THE OFFER.
 
    B.  BACKGROUND; REASONS FOR THE RECOMMENDATION.
 
    In late 1997, in view of increasing consolidation in the Company's market
sectors, the emergence of competitors with greater financial resources, combined
marketing and distribution networks and additional products and services, and
the recent growth in the Company's revenues and earnings, the Board of
 
                                       10
<PAGE>
Directors began considering several alternatives for the Company's future. These
alternatives included (i) staying on its current course and executing the
strategic plan that was in place, (ii) identifying acquisition targets and
implementing an acquisition-oriented growth strategy, and (iii) identifying
potential strategic partners which would merge with or acquire the Company.
 
    In keeping with that approach, in September 1997 the Company engaged The
Nassau Group, Inc. ("Nassau"), an investment banking firm that specializes in
the water and wastewater industry, to assist in its consideration of these
alternatives. In September 1997, Nassau made a presentation to the Board
concerning the valuations of publicly traded enterprises in the pump and valve
industry as well as the more general environmental water and wastewater
treatment industry. Nassau also addressed a variety of strategic options
available to the Company, including the possibility of growth through
acquisitions as well as exit options, such as a sale to domestic or foreign
acquirors. At the same time, the management team made a preliminary
recommendation to the Board that given the dynamic changes occurring among its
own competitors and peers, the Company might best be able to exploit the
opportunities it faced by merging with a strategic player in the industry. The
player would most likely be larger and would also allow the Company to execute
its own niche-oriented strategic plan and provide a challenging and rewarding
growth environment for the Company's employees.
 
    While the Board continued to have confidence in the Company's business
prospects as an independent entity, it determined that the stock market
environment and changes in the competitive landscape made it appropriate to
examine the viability of a merger or sale of the Company at this juncture.
Although the Board did not determine to sell the Company at that point, it
authorized management to have Nassau determine the level of interest among a
defined group of well-financed, potential strategic acquirors.
 
    In October 1997, Nassau prepared a confidential package of descriptive
material on the Company with the cooperation of the Company's senior management
in order to be able to solicit expressions of interest and to respond to
unsolicited inquiries. Between October 1997 and January 1998, Nassau held
discussions with approximately 20 parties, domestic and foreign, with a
strategic interest in the Company. These discussions, conducted under the terms
of confidentiality agreements between the Company and the potential acquirors,
involved the parties' assessment of the Company's business, as well as terms of
potential indications of interest.
 
    In December 1997, Nassau reported to the Board that there were fewer than
five parties which had expressed interest in pursuing an acquisition of the
Company at terms which the Board would find attractive. After consideration, the
Board instructed Nassau and senior management to move forward and negotiate with
one of the prospects, PCC, the best possible transaction.
 
    On December 10, 1997, PCC submitted a preliminary indication of interest.
PCC was invited to attend a management presentation on December 22, 1997, which
it did. PCC subsequently submitted a draft letter of intent to acquire the
Company, which included a proposal that the purchase price be paid in a
combination of $12.50 per Share cash at closing and a contingent payment right
of up to an additional $3.00 per Share in 1999 if the Company achieved certain
revenue and earnings objectives in 1998.
 
    The Company's Board of Directors met in January 1998, and approved the offer
on a preliminary basis, subject to certain clarifications. The Company's legal
and financial advisors contacted PCC to clarify and negotiate certain details of
the contingent payment and other terms and conditions contained in the letter of
intent. On January 21, 1998, the Company and PCC, with the support of their
respective Boards of Directors, executed an exclusive, non-binding letter of
intent and PCC began its due diligence immediately.
 
    After execution and delivery of the letter of intent, PCC entered into a
formal due diligence period during which it received access to the Company's
records and documents and received additional management presentations. After
several weeks of negotiations and due diligence, the Company informed PCC that
it preferred an all-cash transaction, and would be willing to accept a price of
$15.25 per Share in
 
                                       11
<PAGE>
cash at closing. On February 16, 1998, PCC informed the Company that its Board
of Directors had approved the revised terms of the transaction.
 
    On February 24, 1998, Miller, Johnson and Kuehn, Inc. ("MJK") presented a
written opinion to the Company's Board that the proposed transaction was fair to
the Environment One Corporation shareholders from a financial point of view. On
that same day, the Board of Directors held a meeting to discuss the proposed
Offer and Merger, the Merger Agreement, and related matters. After hearing
presentations by the Company's legal and financial advisors, the Board of
Directors considered and discussed the proposed transaction. The Board of
Directors then proceeded to unanimously approve the Offer, the Merger and the
Merger Agreement. The Company executed the Merger Agreement after the close of
business on February 24, 1998.
 
    On February 25, 1998, the Company issued a press release announcing the
execution and delivery of the Merger Agreement.
 
    On March 3, 1998, the Purchaser commenced the Offer.
 
    In reaching its conclusion and recommendation described above, the Board of
Directors considered a number of factors, including the following:
 
    (a) The advantages in a competitive environment of strategically aligning
       with a large, well-capitalized company such as PCC.
 
    (b) The projected financial condition, results of operations, prospects and
       strategic objectives of the Company, as well as the risks involved in
       achieving those prospects and objectives taking into account economic and
       market conditions.
 
    (c) The belief of the Board that, in view of the number of parties canvased
       by management and Nassau and the number of parties who received
       information with respect to the Company, it was unlikely that any
       otherwise desirable party potentially interested in submitting a proposal
       to acquire the Company had not been afforded the opportunity to do so.
 
    (d) The likelihood that the Merger would be consummated, including a
       consideration of the conditions to the Offer and the fact that the Offer
       and the Merger are not subject to a financing contingency.
 
    (e) The financial and other terms and conditions of the Merger Agreement.
 
    (f) The written opinion delivered to the Board by MJK stating that the cash
       consideration to be received by stockholders pursuant to the Offer and
       the Merger is fair to such holders from a financial point of view. A copy
       of the written opinion, which sets forth the assumptions made, procedures
       followed, and other matters considered and limits of the review by MJK,
       is attached hereto as Annex II. STOCKHOLDERS ARE URGED TO READ SUCH
       OPINION IN ITS ENTIRETY.
 
    (g) The fact that the consideration to be received by the stockholders
       pursuant to the Offer represents a premium over the then current
       prevailing market price for the Company's common stock.
 
    (h) The fact that the structure of the acquisition of the Company by PCC
       involves a cash tender offer for all shares to be commenced within five
       business days of the public announcement of the acquisition, to be
       followed promptly by a merger for the same consideration, thereby
       enabling stockholders to obtain cash for their shares at the earliest
       possible time.
 
                                       12
<PAGE>
    (i) The fact that, if required by the fiduciary duties of the Board under
       New York law, the Company may approve or recommend a tender offer
       competing with the PCC offer or terminate the Merger Agreement and enter
       into a definitive acquisition agreement with another party for a
       transaction which is financially superior, subject to payment of the
       applicable termination fee specified in the Merger Agreement.
 
    (j) The fact that PCC had completed its due diligence investigation and that
       the Merger Agreement is not subject to termination as a result of such
       due diligence.
 
    (k) The presentations of Nassau to the Board as to various financial and
       other matters deemed relevant to the Board's consideration.
 
    The Board of Directors' approval and recommendation was based on the
totality of the information considered by it. The Board of Directors did not
assign relative weights to the factors considered by it or determine that any
one factor was of primary importance.
 
ITEM 5. PERSONS RETAINED, EMPLOYED OR TO BE COMPENSATED
 
    Nassau has been retained by the Board of Directors to act as a financial
advisor to the Company with respect to the Offer and the Merger. Pursuant to an
engagement letter with Nassau, the Company (i) has paid Nassau a monthly cash
retainer of $5,000 beginning on September 15, 1997 and continuing on the 15th
day of each succeeding month during the period of Nassau's engagement; (ii) has
issued to Nassau a warrant to purchase 10,000 Shares exercisable within three
years of September 22, 1997, the date of the engagement letter, at an exercise
price equal to the closing price of a Share on September 22, 1997 ($9.125); and
(iii) will pay a transaction fee to Nassau in the amount of 1.1% of the
aggregate consideration in a transaction resulting in a sale of the Company
(approximately $804,000 based upon the $15.25 per Share Offer Price and the
existence of certain long-term indebtedness of the Company) less 50% of the
total cash retainer previously paid (the "Transaction Fee"). The Transaction Fee
is contingent upon closing of such a transaction. The Company has also agreed to
indemnify Nassau and certain related parties against certain liabilities,
including liabilities under the federal securities laws.
 
    MJK was retained by the Board of Directors to render an opinion as to the
fairness, from a financial point of view, to the stockholders of the Company of
the consideration to be paid in the Offer and the Merger. Pursuant to an
engagement letter with MJK, the Company paid MJK a $10,000 cash retainer fee
upon execution of the engagement letter, and an additional $15,000 at the time
MJK rendered its opinion. In addition, the Company has agreed to reimburse MJK
for its reasonable out-of-pocket expenses; provided, however, that MJK must
obtain the prior approval of the Company to any such expenses if the aggregate
of such expenses exceeds $5,000. The Company has also agreed to indemnify MJK
and certain related parties against certain liabilities, including liabilities
under the federal securities laws.
 
    Neither the Company nor any person acting on its behalf has employed,
retained, or compensated any person to make solicitations or recommendations to
the Company's stockholders with respect to the Offer.
 
ITEM 6. RECENT TRANSACTIONS AND INTENT WITH RESPECT TO SECURITIES
 
    a.  Neither the Company nor, to the knowledge of the Company any of its
executive officers, directors, or affiliates, has effected any transaction in
the Company's securities in the past 60 days.
 
    b.  To the knowledge of the Company, all of its executive officers,
directors or affiliates who are also stockholders presently intend to tender
their Shares in the Offer.
 
ITEM 7. CERTAIN NEGOTIATIONS AND TRANSACTIONS BY THE SUBJECT COMPANY
 
    a.  Except as set forth in this statement, the Company is not engaged in any
negotiation in response to the Offer which relates to or would result in (i) an
extraordinary transaction, such as a merger or
 
                                       13
<PAGE>
reorganization involving the Company, (ii) a purchase, sale or transfer of a
material amount of assets by the Company, (iii) a tender offer for or other
acquisition of securities by or of the Company, or (iv) any material change in
the present capitalization or dividend policy of the Company.
 
    b.  Except as described in this transaction, there are no transactions,
resolutions of the Board of Directors, agreements in principle or signed
contracts in response to the Offer that relate to or would result in one or more
of the events referred to in Item 7(a) above.

                       INFORMATION STATEMENT PURSUANT TO
                  SECTION 14(F) OF THE SECURITIES EXCHANGE ACT
                      OF 1934 AND RULE 14(F)-1 THEREUNDER
 
             NO VOTE OR OTHER ACTION OF THE COMPANY'S STOCKHOLDERS
           IS REQUIRED IN CONNECTION WITH THIS INFORMATION STATEMENT.
              NO PROXIES ARE BEING SOLICITED AND YOU ARE REQUESTED
                        NOT TO SEND THE COMPANY A PROXY.
 
    This Information Statement is being furnished to holders of shares of the
common stock, par value $.10 per share (the "Shares"), of Environment One
Corporation, a New York corporation (the "Company"), in connection with the
designation by EOC Acquisition Corporation (the "Purchaser"), a New York
corporation and a wholly owned subsidiary of Precision Castparts Corp. ("PCC"),
an Oregon corporation, of persons (the "PCC Designees") to the Board of
Directors of the Company. Such designation is to be made pursuant to an
Agreement and Plan of Merger dated as of February 24, 1998 (the "Merger
Agreement") among the Company, PCC and the Purchaser.
 
    Pursuant to the Merger Agreement, among other things, the Purchaser
commenced a tender offer on March 3, 1998 to purchase all of the issued and
outstanding Shares at a price of $15.25 per Share, net to the seller in cash, as
described in the Purchaser's Offer to Purchase dated March 3, 1998 and the
related Letter of Transmittal (which Offer to Purchase and related Letter of
Transmittal together constitute the "Offer"). The Offer is scheduled to expire
at 12:00 midnight, eastern time, on Monday, March 30, 1998, unless extended. The
Offer is subject to, among other things, the condition that a number of shares
representing not less than 66 2/3 percent of all outstanding Shares on a fully
diluted basis be validly tendered prior to the expiration of the Offer and not
withdrawn (the "Minimum Condition"). The Merger Agreement also provides for the
merger of the Purchaser with and in to the Company (the "Merger") as soon as
practicable after the consummation of the Offer. Following the consummation of
the Merger (the "Effective Time"), the Company will be the surviving corporation
and a wholly owned subsidiary of PCC. In the Merger, each Share issued and
outstanding immediately prior to the Effective Time (other than Shares held by
PCC, the Purchaser or in the treasury of the Company, all of which will be
canceled) will be converted into the right to receive cash in the amount of
$15.25.
 
    The Merger Agreement provides that promptly upon the Purchaser's
consummation of the Offer, the Purchaser shall be entitled to designate that
number (rounded upward to the next greatest whole number) of directors of the
Company that is equal to the product of the total number of directors on the
Board multiplied by the percentage that the number of Shares then beneficially
owned by the Purchaser and its affiliates bears to the total number of Shares
outstanding. Such actions may require the Company to increase the size of the
Board and/or to secure the resignation of one or more current directors.
 
    The terms of the Merger Agreement, a summary of the events leading up to the
Offer and the execution of the Merger Agreement and other information concerning
the Offer and the Merger are contained in the Offer to Purchase and in the
Solicitation/Recommendation Statement on Schedule 14D-9 of the Company (the
"Schedule 14D-9") with respect to the Offer, copies of which are being delivered
to stockholders of the Company contemporaneously herewith. Certain other
documents (including the Merger Agreement) have been filed with the Securities
and Exchange Commission (the "SEC") as
 
                                      I-1
<PAGE>
Exhibits to the Tender Offer Statement on Schedule 14D-1 of the Purchaser and
PCC (the "Schedule 14D-1") and to the Schedule 14D-9. The Schedule 14D-1 and the
Schedule 14D-9, and the respective exhibits thereto, may be examined at, and
copies thereof may be obtained from, the regional offices and public reference
facilities maintained by the SEC (except that the exhibits thereto cannot be
obtained from the regional offices of the SEC) in the manner set forth in
Sections 7 and 8 of the Offer to Purchase.
 
    No action is required by the stockholders of the Company in connection with
the election or appointment of the PCC Designees to the Board. However, Section
14(f) of the Securities Exchange Act of 1934, as amended, requires the mailing
to the Company's stockholders of the information set forth in this Information
Statement prior to a change in a majority of the Company's directors otherwise
than at a meeting of the Company's stockholders.
 
    The information contained in this Information Statement concerning PCC, the
Purchaser and the PCC Designees has been furnished to the Company by such
persons, and the Company assumes no responsibility for the accuracy or
completeness of such information. The Schedule 14D-1 indicates that the
principal executive offices of the Purchaser and PCC are located at 4650 SW
Macadam Avenue, Suite 440, Portland, Oregon 97201.
 
                                    GENERAL
 
    The Shares are the only class of voting securities of the Company
outstanding. Each Share is entitled to one vote on matters submitted to a vote
of the Company's stockholders. As of March 3, 1998, there were 4,295,827 Shares
issued and outstanding, and 426,422 Shares subject to outstanding options and
warrants.
 
                               THE PCC DESIGNEES
 
    PCC has informed the Company that each of the PCC Designees listed below has
consented to act as a director of the Company. It is expected that the PCC
Designees may assume office at any time following the consummation of the Offer,
which cannot be earlier than March 30, 1998, and that, upon assuming office, the
PCC Designees will thereafter constitute at least 66 2/3 percent of the total
number of directors on the Board.
 
    Biographical information concerning each of the PCC Designees is presented
below.

                  BOARD COMMITTEES, COMPENSATION AND MEETINGS
 
    The Board of Directors held six meetings during the year ended December 31,
1997. During this period, each Director attended at least 75% of the aggregate
of the total number of meetings of the Board and meetings of Board committees on
which he served. Among its standing committees, the Board has an Audit
Committee, Executive Committee, and Human Resource Committee. The Board does not
have a Nominating Committee.
 
    The Audit Committee meets once a year and serves as the Board's direct
liaison with the Company's independent public auditors, reviewing and discussing
the auditors' annual internal control recommendations and making such other
inquiries and recommendations as it deems necessary. The Audit Committee
consists of Walter W. Aker, Stephen V. Ardia and Angelo Dounoucos.
 
    The Executive Committee currently consists of John L. Allen, Stephen V.
Ardia, Angelo Dounoucos, and Robert G. James. The Executive Committee meets on
call and has authority to act on most matters during the intervals between Board
Meetings. The Executive Committee met four times during the 1997 fiscal year.
 
    The Human Resource Committee met once during the 1997 fiscal year. The Human
Resource Committee reviews and makes recommendations to the Board regarding
compensation matters, adjustments in compensation for officers and employees,
and employee benefit matters. Currently, the Human Resource Committee consists
of John L. Allen, Stephen V. Ardia, Robert G. James, and Rolf E. Soderstrom.
 
    As compensation for attendance at Board and Committee meetings, directors
who are not employees of the Company receive a stock grant on September 1st of
each year for a number of shares having an
 
                                      I-5
<PAGE>
aggregate value of $10,000, based upon the fair market value of the Company's
common stock at the close of business on the date of grant. In addition,
non-employee directors receive a grant of stock options on the third Tuesday of
each December. Each such grant to a director relates to a total number of shares
of the Company's common stock having an aggregate fair market value, at the
close of business on the date of grant, equal to $10,000. The exercise price of
these options is fixed at the fair market value of the Company's common stock at
the close of business on the date of grant. The Board of Directors believes that
this equity-based system of compensation is beneficial in that it more closely
aligns the long-term interests of directors with those of the Company's
shareholders.

EMPLOYMENT AGREEMENT AND CHANGE OF CONTROL AGREEMENT WITH MR. ARDIA
 
    Pursuant to the Merger Agreement, the Company has entered into an Employment
Agreement with Mr. Ardia, providing for Mr. Ardia to serve as the Company's
President for a term of one year beginning on the date that the Offer is
consummated, after which his employment may be continued on an at-will basis by
mutual agreement of the parties. The agreement provides that Mr. Ardia will be
paid a base salary at the annual rate of $150,000 (which is consistent with his
current salary arrangements). He will be entitled to participate in the
Company's bonus plan through December 31, 1998, and in a similar bonus plan
during the three month period January 1, 1999 through March 28, 1999. Mr. Ardia
will also be entitled to participate in PCC's stock option and stock purchase
programs, in accordance with the terms of those programs. Mr. Ardia may
terminate the agreement upon thirty days' written notice to the Company any time
after the first three months of its effectiveness.
 
    The Company also has a Change in Control Agreement with Mr. Ardia dated
January 5, 1998, providing for a payment to Mr. Ardia upon the occurrence of a
"Change of Control" (as defined in the agreement) equal to (i) the amount of his
annual base salary in effect on the date of the Change of Control, and (ii) an
amount equal to the sum of (A) the bonus payable to Mr. Ardia for the year
during which the Change of Control occurs, prorated through the date of the
Change of Control, plus (b) the average annual bonus paid to Mr. Ardia for the
two complete fiscal years that precede the fiscal year during which the Change
of Control occurs. In addition, the Company shall waive for twelve months
following his termination any required premium payment due from Mr. Ardia to
allow him to continue his coverage under the Company's group health plan. A
"Change of Control," as defined in the agreement, would occur upon the
Purchaser's acceptance for payment and payment for Shares pursuant to the Offer.
 
EMPLOYMENT AGREEMENTS WITH MESSRS. ALEXANDER, DOIN, EARLE AND WELSH
 
    Pursuant to the Merger Agreement, the Company has also entered into
Employment Agreements with Mr. Alexander to serve as Vice President of
Marketing; Mr. Doin to serve as Vice President, General Manager; Mr. Earle to

Finance. These agreements provide for an annual salary of $95,000 for Mr.
Alexander, $90,000 for Mr. Doin, $80,000 for Mr. Earle, and $80,000 for Mr.
Welsh, respectively (which are consistent with their current salary
arrangements). Each of the foregoing employees will be entitled to participate
in the Company's bonus plan through December 31, 1998, and in a similar bonus
program for the three month period January 1, 1999 through March 28, 1999.
Thereafter, any bonus program provided will be consistent with bonus programs
provided by PCC to similarly situated employees. These employees will also be
entitled to participate in PCC's stock option and stock purchase programs, in
accordance with the terms of those programs.
 
                                      I-8
<PAGE>
    The agreements, which may be terminated by either party upon thirty days'
written notice, provide for a severance benefit equal to the following: (i) if
the employee is terminated before the first anniversary of the effective date of
the agreement, the remaining balance of the employee's base salary for the
portion of year from the date of termination until the first anniversary of the
effective date, plus 100% of any calendar year 1998 bonus to which the employee
would have been entitled had he or she remained employed by the Company through
December 31, 1998, plus the Severance Payment (as defined below); or (ii) if the
employee is terminated after the first anniversary of the effective date of the
agreement and prior to the second anniversary of the effective date, ten months'
pay at the employee's then current salary level (the "Severance Payment"). In
addition, the Company shall waive for the remainder of the unexpired term of the
agreement any required premium payment due from the employee to allow the
employee to continue his or her coverage under the Company's group health plan.
The employee is ineligible for the payments described in this paragraph if he or
she voluntarily resigns or withdraws from employment, is terminated for "cause"
(as defined in the agreement), terminates employment as a result of the
expiration of the term of the agreement, breaches certain confidentiality or
non-competition provisions in the agreement, or accepts reasonably comparable
employment with an affiliate of PCC.
 
                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
    Rolf E. Soderstom, who is a member of the Company's Board of Directors, is
also a managing director of The Nassau Group, Inc. ("Nassau"), an investment
banking firm. Nassau has been retained by the Board of Directors to act as a
financial advisor to the Company with respect to the Offer and the Merger.
Pursuant to an engagement letter with Nassau, the Company (i) has paid Nassau a
monthly cash retainer of $5,000 beginning on September 15, 1997 and continuing
on the 15th day of each succeeding month during the period of Nassau's
engagement; (ii) has issued to Nassau a warrant to purchase 10,000 Shares
exercisable within three years of September 22, 1997, the date of the engagement
letter, at an exercise price equal to the closing price of a Share on September
22, 1997 ($9.125); and (iii) will pay a transaction fee to Nassau in the amount
of 1.1% of the aggregate consideration in a transaction resulting in a sale of
the Company (approximately $804,000 based upon the $15.25 per Share Offer Price
and the existence of certain long-term indebtedness of the Company) less 50% of
the total cash retainer previously paid (the "Transaction Fee"). The Transaction
Fee is contingent upon closing of such a transaction. The Company has also
agreed to indemnify Nassau and certain related parties against certain
liabilities, including liabilities under the federal securities laws.
 
            SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
 
    Section 16(a) of the Exchange Act requires the Company's directors,
executive officers and holders of more than 10% of the Company's common stock
(collectively, "Reporting Persons") to file with the SEC initial reports of
ownership and reports of changes in ownership of the Company's common stock.
Such persons are required by regulations of the SEC to furnish the Company with
copies of all such filings. Based on its review of the copies of such filings
received by it with respect to the fiscal year ended December 31, 1997, the
Company believes that all Reporting Persons complied with all Section 16(a)
filing requirements in the fiscal year ended December 31, 1997, except for the
following: Mr. Dounoucos filed a late Form 5 with respect to one transaction and
failed to include on his Form 5 an additional transaction, each of which
occurred in 1997 under stock-based compensation plans maintained by the Company
for non-employee directors; Mr. Grenback did not file a required Form 4 with
respect to three transactions occurring in 1997; and each of Messrs. Allen,
Aker, Grenback, James and Soderstrom failed to file a Form 5 with respect to two
transactions under stock-based compensation plans maintained by the Company for
non-employee directors.

Board of Directors
 
Environment One Corporation
 
2773 Balltown Road
 
Niskayuna, NY 12309-1090
 
Members of the Board,
 
    You have requested our opinion as to whether the consideration to be
received by the shareholders of the Company pursuant to the acquisition (the
"Transaction") of all the issued and outstanding shares of capital stock of
Environment One Corp. (the "Company") on a fully diluted basis ("Common Stock")
by Precision Castpart Corp. (the "Acquiror") is fair, from a financial point of
view.
 
    We are not opining as to any other transactions or contractual arrangements
previously entered into, or to be entered into (whether or not in connection
with the Transaction) between the Company, or its Board of Directors or
management, on the one hand, and the Acquiror (or any of its affiliates) or any
other person, on the other, including without limitation, any agreements entered
into and the payments made in connection therewith. Additionally, our opinion
relates solely to whether the consideration is fair, from a financial point of
view, to the shareholders of the Company and we have not been requested to opine
to, and this opinion does not in any manner address, the Company's underlying
decision to proceed with or effect the Transaction.
 
    We understand that (i) the purchase price per share to be paid by the
Acquiror for the Common Stock will be $15.25 in cash; (ii) the aggregate
consideration to be received by the shareholders of the Company in connection
with the Transaction is $72,014,297, and; (iii) the Acquiror will attempt to
purchase the Common Stock from the shareholders of the Company after announcing
a tender offer to the shareholders for the consideration mentioned in (i) above.
 
    As a customary part of our investment banking business, we are engaged in
the valuation of businesses and their securities in connection with mergers and
acquisitions, underwriting and secondary distributions of securities, private
placements, and valuations for estate, corporate and other purposes. For our
services in rendering this opinion, the Company will pay us a fee and indemnify
us against certain liabilities. We have never managed a public offering of stock
for either the Company or the Acquiror, have not acted as a financial advisor in
the Transaction for either the Company or the Acquiror, do not provide research
coverage on the Company or the Acquiror and, in the ordinary course of our
business, do not make a market in the stock of either the Company or the
Acquiror.
 
    In arriving at our opinion, we have undertaken such review, analyses and
inquiries as we have deemed necessary and appropriate under the circumstances.
As the Transaction is to provide the shareholders of the Company with cash and
not securities of any kind from the Acquiror, we have limited our evaluation to
a review of the business and financial condition of the Company. Among other
things, we have reviewed, but have not limited our review to: (i) the Letter of
Intent, dated January 21, 1998, signed by both the Company and the Acquiror;
(ii) a draft of the Agreement and Plan of Merger dated February 22, 1998,
between the Acquiror and the Company, which we assume will conform in all
substantive respects to the definitive executed agreement; (iii) the Descriptive
Memorandum dated November 1997 provided by The
 
                                      II-1
<PAGE>
Nassau Group, Inc. (the "Memorandum") and; (iv) the Project Pump Status Report,
dated December 16, 1997, provided by The Nassau Group, Inc. In addition we have
(i) conducted interviews with management of the Company; (ii) toured its
facilities; (iii) reviewed and discussed with Company management the three year
financial projections included in the Memorandum, which, on our request, has
been augmented by the Company to include a balance sheet and statement of cash
flows; (iv) reviewed financial and other publicly available information with
respect to the Company including annual reports, Forms 10-KSB and 10-QSB and
proxy statements; (v) consulted government and industry economic statistics that
could have a direct bearing on the company; and (vi) examined securities data on
comparable mergers and acquisitions of similar public companies, to the extent
available.
 
    In conducting our analysis and arriving at the opinion contained herein, (i)
we have relied upon and assumed the accuracy and completeness of the financial
and other information (including the financial statements and projections of the
Company) provided to us and prepared by The Nassau Group, Inc. and the Company's
senior management and their representations relating thereto, and we have not
independently verified any such information or representations; (ii) with
respect to the Company's projections, budgets and current estimates, we have
assumed based upon representations of the Company's senior management that they
have been reasonably prepared on bases reflecting the best currently available
estimates and judgments of the Company's senior management as to the expected
future performance of the Company; (iii) we have relied upon and assumed the
accuracy and completeness of the information provided by, and the
representations of, the Company's senior management in respect of which our
understandings set forth on this opinion are based (including, without
limitation, the representations of the Company's senior management that the
final terms and conditions of the operative documents referred to in the
preceding paragraph will, in all material respects, reflect the terms and
conditions set forth in the drafts of such documents that were provided to us);
(iv) we do not assume any responsibility for the information or current
estimates provided to us and we have further relied upon the assurance of the
Company's senior management that they are unaware of any facts that would make
the information provided to us incomplete or misleading; (v) we have not
performed or obtained any independent appraisals or valuations of specific
assets of the Company and we express no opinion as to its liquidation value;
(vi) our analysis is necessarily based on economic, monetary, market and other
conditions existing and which can be evaluated as of the date of our opinion;
however such conditions are subject to rapid and unpredictable change; and (vii)
we have not been authorized by the Company or the Board to solicit, nor have we
solicited, offers for transactions alternative to the Transaction, nor have we
been asked to advise the Company or the Board as to financial alternatives to
the Transaction.
 
    Finally, in rendering our opinion, we have considered the current price per
share of the Company's Common Stock and current market conditions. We have also
examined the trading volume and liquidity of the Company's Common Stock and its
current price per share in historical context of the last four years.
 
    This opinion in intended solely for the benefit and use of the Board as one
element in its consideration of the proposed Transaction. This opinion is not to
be used for any other purpose or reproduced, disseminated, quoted or referred to
at any time, in whole or in part, in any manner, or for any purpose, without our
prior written consent.
 
    Based upon and subject to the foregoing, and upon such other factors as we
consider relevant, it is our opinion that the consideration to be received by
the shareholders of the Company pursuant to the Transaction is fair, from a
financial point of view, to the shareholders of the Company.
 
                                          Very truly yours,
 
                                          Miller, Johnson & Kuehn, Inc.

<PAGE>

                                   AGREEMENT

      NOW, THEREFORE, in consideration of the mutual representations, 
warranties, covenants, agreements and conditions contained in this Agreement, 
the parties agree as follows:

                                   ARTICLE 1

                                   THE OFFER

      1.1   THE OFFER.

            1.1.1 Provided that this Agreement has not been terminated in 
accordance with Article 8 and provided that none of the conditions and events 
set forth in ANNEX A to this Agreement (the Offer Conditions) have occurred 
(unless such event shall have been waived by Sub), as promptly as practicable 
but in no event later than five (5) business days after the public 
announcement of Sub's intention to commence the Offer, PCC shall cause Sub to 
commence (within the meaning of Rule 14d-2(a) under the Securities Exchange 
Act of 1934, as amended (the Exchange Act)) a cash tender offer to purchase 
all of the Shares for $15.25 per Share, net to the seller in cash (the Offer 
Price).  The terms of the Offer will provide that, subject to Sub's right to 
extend the Offer pursuant to Section 1.1.2 below, the Offer will expire on 
the date that is twenty (20) business days from the date the Offer is 
commenced (such date, or the date through which the Offer may be extended 
pursuant to Section 1.1.2 below, the Expiration Date).

            1.1.2 Sub reserves the right in its sole discretion to change or 
waive any condition, to increase the Offer Price, and to make any other 
changes in the terms and conditions of the Offer; PROVIDED, HOWEVER, that Sub 
may not without the prior written consent of E/One, (i) decrease the Offer 
Price, (ii) change or waive the Minimum Condition, (iii) decrease the number 
of Shares sought pursuant to the Offer, (iv) impose conditions in addition to 
the Offer Conditions or (v) otherwise amend the Offer in any manner adverse 
to E/One's stockholders. Notwithstanding the foregoing, Sub may, without 
E/One's consent (x) extend the Offer, if at such original Expiration Date the 
Minimum Condition (as defined below) or any of the Offer Conditions have not 
been satisfied or waived; (y) extend the Offer for any period required by any 
rule, regulation, interpretation or position of the Securities and Exchange 
Commission (the SEC); or (z) extend the Offer for no more than ten (10) 
business days beyond the original Expiration Date contemplated by 
Section 1.1.1 in the event that the Offer Conditions have been satisfied but 
less than ninety percent (90%) of the Shares have been tendered pursuant to 
the Offer.

            1.1.3 On the date the Offer is commenced, Sub will file with the 
SEC a Tender Offer Statement on Schedule 14D-1 (together with all amendments 
and supplements thereto, the Schedule 14D-1) with respect to the Offer.  
The Schedule 14D-1 will contain as an exhibit or incorporate by reference the 
Offer to Purchase (or portions thereof) and form of the related letter


                                       2
<PAGE>

of transmittal and summary advertisement to be used in connection with the 
Offer (the Schedule 14D-1 and such other documents, together with any 
supplements thereto or amendments thereof, being referred to herein 
collectively as the Offer Documents).  E/One will provide to Sub in writing 
all information regarding E/One necessary for the preparation of the Offer 
Documents, and E/One and its counsel will be given a reasonable opportunity 
to review and comment on the Offer Documents before they are filed with the 
SEC and distributed to E/One's stockholders.  Sub will provide to E/One and 
its counsel any comments that Sub receives (directly or through its counsel) 
from the SEC or its staff with respect to the Offer Documents promptly after 
receiving such comments.  Sub and E/One will each promptly correct any 
information provided by it for use in the Offer Documents if and to the 
extent that it has become false or misleading in any material respect, and 
Sub will promptly amend and supplement the Offer Documents if and to the 
extent that they have become false or misleading in any material respect and 
will promptly cause the Offer Documents as so amended and supplemented to be 
filed with the SEC and to be disseminated to E/One's stockholders, in each 
case as and to the extent required by applicable federal securities laws.

            1.1.4 The obligation of Sub to accept for payment and pay for 
Shares tendered pursuant to the Offer shall be subject only to (i) the 
condition (the Minimum Condition) that at least the number of Shares that 
constitute two-thirds of the then outstanding Shares on a fully diluted basis 
(including, without limitation, all Shares issuable upon the conversion of 
any convertible securities or upon the exercise of any options, warrants or 
rights, whether or not vested or exercisable) shall have been validly 
tendered and not withdrawn prior to the expiration of the Offer and (ii) the 
satisfaction or waiver of the other conditions set forth in Annex A (the 
Offer Conditions).  Subject only to the Minimum Condition and the Offer 
Conditions, in accordance with the terms of the Offer, Sub will, and PCC will 
cause Sub to, accept for payment all Shares validly tendered and not 
withdrawn (the Tendered Shares) as soon as legally permissible after 
commencement of the Offer, and pay for all Tendered Shares as promptly as 
practicable thereafter.  PCC shall provide or cause to be provided to Sub on 
a timely basis the funds necessary to accept for payment, and pay for, any 
Shares that Sub becomes obligated to accept for payment, and pay for, 
pursuant to the Offer.

      1.2   ACTIONS BY E/ONE.

            1.2.1 E/One hereby approves of and consents to the Offer and 
represents and warrants that the E/One Board, at a meeting duly called and 
held on February 24, 1998 unanimously has (i) determined that this Agreement 
and the transactions contemplated hereby, including the Offer, are fair to 
and in the best interests of E/One's stockholders, (ii) approved this 
Agreement and the transactions contemplated hereby, including the Offer, and 
(iii) resolved to recommend that the stockholders of E/One accept the Offer, 
tender their Shares to Sub and, if required by applicable law, approve the 
transactions contemplated hereby. E/One has been advised by each of its 
directors that each such person intends to tender all Shares, if any, that he 
or she owns pursuant to the Offer.  E/One further represents and warrants 
that Miller, Johnson & Kuehn, Inc. has delivered to the E/One Board its 
written opinion dated February 24, 1998 to 


                                       3
<PAGE>

the effect that, as of the date of such opinion, the amount of the Offer 
Price and the Merger Consideration (as defined in Section 3.1.1 below) are 
fair to E/One's stockholders from a financial point of view.  Miller, Johnson 
& Kuehn, Inc. has agreed to permit the inclusion of its fairness opinion or 
references thereto in the Offer Documents and the Schedule 14D-9 referred to 
below and the Proxy Statement referred to in Section 2.2.1 (subject to its 
review and approval of the description of the fairness opinion), and E/One 
consents to the inclusion in the Offer Documents of the recommendations of 
the E/One Board described in this Section 1.2.

            1.2.2 As soon as practicable following commencement of the Offer, 
E/One will file with the SEC a Solicitation/Recommendation Statement on 
Schedule 14D-9 pertaining to the Offer (together with any amendments or 
supplements thereto, the Schedule 14D-9) containing the E/One Board's 
recommendation described in Section 1.2.1 and will promptly disseminate the 
Schedule 14D-9 to E/One's stockholders to the extent required by Rule 14d-9 
promulgated under the Securities Exchange Act of 1934, as amended (the 
Exchange Act) and any other applicable federal securities law.  Sub and its 
counsel will be given a reasonable opportunity to review and comment on the 
Schedule 14D-9 before it is filed with the SEC and disseminated to E/One's 
stockholders.  E/One will provide to PCC and Sub and their counsel any 
comments that E/One receives (directly or through its counsel) from the SEC 
or its staff with respect to the Schedule 14D-9 promptly after receiving such 
comments.  E/One, PCC and Sub agree to correct promptly any information 
provided by any of them for use in the Schedule 14D-9 that shall have become 
false or misleading, and E/One further agrees to take all steps necessary to 
cause the Schedule 14D-9 as so corrected to be filed with the SEC and 
disseminated to holders of Shares. In each case, PCC and Sub and their 
counsel shall be given an opportunity to review and comment on the Schedule 
14D-9 and any amendments thereto prior to the filing thereof with the SEC.

            1.2.3 E/One will promptly furnish Sub with mailing labels, 
security position listings and any available listing or computer files 
containing the names and addresses of the record holders of the Shares as of 
a recent date and furnish Sub with such additional information and assistance 
(including, without limitation, updated lists of stockholders, mailing labels 
and lists of securities positions) as Sub or its agents may reasonably 
request for the purpose of communicating the Offer to the record and 
beneficial holders of Shares.  Subject to the requirements of applicable law, 
and except for such steps as are necessary to disseminate the Offer Documents 
and any other documents necessary to consummate the Merger, PCC and Sub and 
their agents will hold in confidence the information contained in any such 
labels, listings, and files, will use such information only in connection 
with the Offer and the Merger, and if this Agreement is terminated, will upon 
E/One's request deliver and will use their best efforts to cause their agents 
to deliver to E/One all copies of and any extracts or summaries from such 
information then in their possession and control.

      1.3   DESIGNATION OF DIRECTORS OF E/ONE FOLLOWING COMPLETION OF OFFER.

            1.3.1 Promptly upon Sub's consummation of the Offer, Sub will be
entitled, subject to compliance with Section 14(f) of the Exchange Act, to
designate that number (rounded 


                                       4
<PAGE>

up to the next greatest whole number) of directors on the E/One Board that is 
equal to the product of the total number of directors on the E/One Board 
multiplied by the percentage that the aggregate number of Shares beneficially 
owned by Sub or any affiliate of Sub bears to the number of Shares 
outstanding.  E/One will cause (i) each committee of the E/One Board, 
(ii) the board of directors of each subsidiary of E/One, and (iii) each 
committee of such board to include persons designated by Sub constituting the 
same percentage of each such committee or board as Sub's designees are of the 
E/One Board.  E/One will, upon request by Sub, promptly increase the size of 
the E/One Board or exercise its best efforts to secure the resignations of 
such number of directors as is necessary to enable Sub designees to be 
elected to the E/One Board and to cause Sub's designees to be so elected.

            1.3.2 Subject to applicable law, E/One will promptly take all 
action necessary pursuant to Section 14(f) of the Exchange Act and Rule 14f-1 
promulgated thereunder in order to fulfill its obligations under this 
Section 1.3 and will include in the Schedule 14D-9 disseminated to 
stockholders promptly after the commencement of the Offer (or an amendment 
thereof or an information statement pursuant to Rule 14f-1 if Sub has not 
theretofore designated directors) such information with respect to E/One and 
its officers and directors as is required under Section 14(f) and Rule 14f-1 
in order to fulfill its obligations under this Section 1.3.  PCC and Sub will 
supply to E/One and be solely responsible for any information with respect to 
itself and its nominees, officers, directors and affiliates required by 
Section 14(f) and Rule 14f-1.

                                   ARTICLE 2

                                  THE MERGER

      2.1   THE MERGER.  Pursuant to the NYBCL, and subject to and in 
accordance with the terms and conditions of this Agreement, Sub will be 
merged with and into E/One at the Effective Time, as defined in Section 2.4.

      2.2   STOCKHOLDERS' MEETING; PROXY STATEMENT.

            2.2.1 If required by applicable law in order to consummate the 
Merger, E/One will, in accordance with New York law and E/One's Articles of 
Incorporation and Bylaws, call and hold a special meeting of its stockholders 
(the Stockholders' Meeting) as soon as practicable following the date on 
which the Offer is consummated for the purpose of approving the Merger.  
Subject to Section 6.2.2, the E/One Board will recommend to its stockholders 
that the Merger be approved, and E/One will use its best efforts to solicit 
from its stockholders proxies in favor of the approval of the Merger 
(Stockholder Approval), and will take all other action necessary or 
advisable to secure the vote or consent of stockholders required by New York 
law to obtain such consents.

            2.2.2 E/One will, as soon as practicable following the 
consummation of the Offer, prepare and file a preliminary Proxy Statement to 
solicit Stockholder Approval (the Proxy


                                       5
<PAGE>

Statement) with the SEC and will use its best efforts to respond to any 
comments of the SEC or its staff and to cause the Proxy Statement, as 
finalized, to be mailed to E/One's stockholders as promptly as practicable 
after responding to all such comments to the satisfaction of the staff.  Sub 
and PCC will provide to E/One in writing all information regarding Sub and 
PCC necessary for the preparation of the Proxy Statement.  E/One will notify 
PCC promptly of the receipt of any comments from the SEC or its staff and of 
any request by the SEC or its staff for amendments or supplements to the 
Proxy Statement or for additional information and will supply PCC with copies 
of all correspondence between E/One or any of its representatives, on the one 
hand, and the SEC or its staff, on the other hand, with respect to the Proxy 
Statement or the Merger.  If at any time before the Stockholders' Meeting 
there occurs any event that should be set forth in an amendment or supplement 
to the Proxy Statement, E/One will promptly prepare and mail to its 
stockholders such an amendment or supplement.  E/One will not mail any Proxy 
Statement, or any amendment or supplement thereto, to which PCC reasonably 
objects.  The Proxy Statement will include the E/One Board's recommendation 
that E/One's stockholders grant proxies to approve the Merger; provided, 
however, that such recommendation may be withdrawn, modified, or amended if 
and to the extent the E/One Board determines, in good faith after 
consultation with outside legal counsel, that a failure to do so would be 
contrary to its fiduciary obligations.

      2.3   MERGER WITHOUT STOCKHOLDERS' MEETING.  Notwithstanding any other 
provision in this Agreement, if PCC, Sub, or any affiliate of either of them 
beneficially owns at least 90% of the outstanding Shares, the parties agree 
to take all necessary and appropriate action to cause the Merger to become 
effective as soon as practicable after the Expiration Date, but in no event 
later than ten business days thereafter, without a meeting of stockholders of 
E/One in accordance with Section 905 of the NYBCL.

      2.4   EFFECTIVE TIME.  As soon as practicable after satisfaction or 
waiver of all of the conditions to the Merger set forth in Article 7 of this 
Agreement, a Certificate of Merger or Consolidation prepared in accordance 
with Section 901 and 904 of the NYBCL and any other applicable provisions of 
the NYBCL (the Certificate of Merger) will be executed and filed with the 
Secretary of State of the State of New York.  The Merger will be effective on 
the date and at the time (the Effective Time) when the Certificate of 
Merger has been accepted for filing by the Secretary of State of the State of 
New York.  The day during which the Effective Time occurs is referred to

will be a single corporation (the Surviving Corporation) and will continue 
to be governed by the laws of the State of New York.

      2.6   ARTICLES OF INCORPORATION AND BYLAWS.  The Articles of 
Incorporation and Bylaws of E/One as in effect at the Effective Time will be

NYBCL.

                                   ARTICLE 3

                             MERGER CONSIDERATION

      3.1   EFFECT OF MERGER ON CAPITAL STOCK OF CONSTITUENT CORPORATIONS.  
As of the Effective Time, by virtue of the Merger and without any action on 
the part of the holder of any Shares or any shares of capital stock of Sub:

            3.1.1 CONVERSION OF E/ONE SHARES.  Subject to Section 3.1.5, each 
Share issued and outstanding immediately prior to the Effective Time (other 
than Shares to be canceled in accordance with Section 3.1.2) will be 
converted into the right to receive from the surviving corporation a cash 
payment in the amount of $15.25 (the Merger Consideration). As of the 
Effective Time, all the Shares 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 Merger 
Consideration, without interest.

            3.1.2 CANCELLATION OF TREASURY STOCK AND SHARES OWNED BY PCC 
PARTIES. Each Share that is held in the treasury of E/One and any Shares 
owned by PCC or Sub immediately before the conversion pursuant to 
Section 3.1.1 will automatically be canceled and retired and will cease to 
exist, and no consideration will be delivered in exchange therefor.

            3.1.3 CAPITAL STOCK OF SUB.  Each issued and outstanding share of 
capital stock of Sub will be converted into and become one fully paid and 
nonassessable share of E/One Common Stock.

            3.1.4 WITHHOLDING TAX.  The right of any stockholder to receive 
the Merger Consideration will be subject to and reduced by the amount of any 
required tax withholding obligation.


                                       7
<PAGE>

            3.1.5 SHARES OF DISSENTING STOCKHOLDERS. Notwithstanding anything 
in this Agreement to the contrary, if any shareholder of E/One who has not 
voted such Shares in favor of or consented to the Merger and who is entitled 
to dissent from the Merger and require appraisal for his or her Shares under 
the NYBCL (a Dissenting Stockholder) and complies with all the provisions 
of Section 910 of the NYBCL concerning the right of holders of Shares to 
dissent from the Merger and require appraisal of their Shares (Dissenting 
Shares) will not be converted as described in Section 3.1.1 but will become 
the right to receive such consideration as may be determined to be due to 
such Dissenting Stockholder pursuant to the laws of the State of New York.  
If, after the Effective Time, such Dissenting Stockholder (if any) withdraws 
his or her demand for appraisal or fails to perfect or otherwise loses his or 
her right of appraisal, in any case pursuant to NYBCL, his or her Shares will 
be deemed to be converted as of the Effective Time into the right to receive 
the Merger Consideration.  E/One will give PCC and Sub (i) prompt notice of 
any demands for appraisal of Shares received by E/One and (ii) the 
opportunity to participate in and direct all negotiations and proceedings 
with respect to any such demands.  E/One will not, without the prior written 
consent of PCC, make any payment with respect to, or settle, offer to settle, 
or otherwise negotiate, any such demands.

      3.2   EXCHANGE OF CERTIFICATES.

            3.2.1 PAYING AGENT.  Before the Effective Time, PCC and E/One 
will designate a mutually acceptable bank or trust company to act as paying 
agent in the Merger (the Paying Agent).  From time to time on, before or 
after the Effective Time, PCC will make available, or cause the Surviving 
Corporation to make available, to the Paying Agent funds in amounts and at 
the times necessary for the payment of the Merger Consideration upon 
surrender of certificates representing Shares outstanding immediately prior 
to the Effective Time (other than Shares owned by Sub) as part of the Merger 
pursuant to Section 3.1.1, it being understood that any and all interest 
earned on funds made available to the Paying Agent pursuant to this Agreement 
will be turned over to PCC.

            3.2.2 EXCHANGE PROCEDURE.  As soon as reasonably practicable 
after the Effective Time, the Paying Agent will mail to each holder of record 
of a certificate or certificates that immediately before the Effective Time 
represented Shares (the Certificates), (i) a notice (advising the holders 
that the Merger has become effective) and a letter of transmittal in 
customary and appropriate form (which will specify that delivery will be 
effected, and risk of loss and title to the Certificates will pass, only upon 
proper delivery of the Certificates to the Paying Agent) and (ii) 
instructions for use in effecting the surrender of the Certificates in 
exchange for the Merger Consideration.  Upon surrender of a Certificate for 
cancellation to the Paying Agent or to such other agent or agents as may be 
appointed by PCC or Sub, together with such letter of transmittal, properly 
completed and duly executed, and such other customary documents as may 
reasonably be required by the Paying Agent, the holder of such Certificate 
will be entitled to receive in exchange therefor the amount of cash into 
which the Shares theretofore represented by such Certificate have been 
converted pursuant to Section 3.1, and the Certificate so surrendered will be 
canceled.  In the event of a transfer of ownership of Shares that is not 
registered in the transfer 


                                       8
<PAGE>

records of E/One, payment may be made to a Person (as defined in Section 3.2.4
below) other than the Person in whose name the Certificate so 
surrendered is registered, if such Certificate is properly endorsed or 
otherwise is in proper form for transfer and the Person requesting such 
payment pays any transfer or other taxes required by reason of the payment to 
a Person other than the registered holder of such Certificate or establishes 
to the satisfaction of the Surviving Corporation that such tax has been paid 
or is not applicable.  Until surrendered as contemplated by this 
Section 3.2.2, each Certificate will be deemed at any time after the 
Effective Time to represent only the right to receive upon such surrender the 
Merger Consideration, without interest, into which the Shares theretofore 
represented by such Certificate will have been converted pursuant to 
Section 3.1.1.  No interest will be paid or will accrue on the cash payable 
upon the surrender of any Certificate.

            3.2.3 NO FURTHER OWNERSHIP RIGHTS IN E/ONE COMMON STOCK.  All 
cash paid upon the surrender of Certificates in accordance with the terms of 
Sections 3.1 will be deemed to have been paid in full satisfaction of all 
rights pertaining to the Shares theretofore represented by such Certificates. 
At the Effective Time, the stock transfer books of E/One will be closed, and 
there will be no further registration of transfers on the stock transfer 
books of the Surviving Corporation of the Shares that were outstanding 
immediately before the Effective Time.  If, after the Effective Time, 
Certificates are presented to the Surviving Corporation or the Paying Agent 
for any reason, they will be canceled and exchanged as provided in 
Section 3.1.

            3.2.4 NO LIABILITY.  None of PCC, Sub, E/One, or the Paying Agent 
will be liable to any Person in respect of any cash or security delivered to 
a public official pursuant to any applicable abandoned property, escheat, or 
similar law.  As used in this Agreement, the term Person means any 
individual, corporation, general partnership, limited partnership, limited 
liability company, joint venture, trust, cooperative or other association, 
Governmental Entity (as defined in Section 4.2(b) below), or any other 
organization.

            3.2.5 LOST, STOLEN, OR DESTROYED CERTIFICATES.  In the event that 
any Certificate has been lost, stolen, or destroyed, upon the making of an 
affidavit of that fact by the Person claiming such Certificate to be lost, 
stolen, or destroyed, E/One will issue in exchange for such lost, stolen, or 
destroyed Certificate, the Merger Consideration deliverable in respect 
thereof as determined in accordance with this Agreement; PROVIDED, HOWEVER, 
that E/One may, in its sole discretion and as a condition precedent to the 
issuance thereof, require the owner of such lost, stolen, or destroyed 
Certificate to give E/One a bond in such sum as it may reasonably direct as 
indemnity against any claim that may be made against E/One with respect to 
the certificate alleged to have been lost, stolen, or destroyed.

      3.3   E/ONE STOCK OPTIONS AND WARRANT.  E/One shall use its best 
efforts to enter into an agreement with each holder of stock options, vested 
and unvested, outstanding under E/One's 1996 Incentive Compensation Plan, 
1996 Incentive Compensation Plan for Non-Employee Directors, and 1972 Stock 
Option Plan (the Plans) and the outstanding warrants to purchase E/One 
common stock, which agreement provides that, immediately after the date on 
which Sub 


                                       9
<PAGE>

shall have accepted for payment all Shares validly tendered and not withdrawn 
prior to the expiration date with respect to the Offer (the Tender Offer 
Acceptance Date), each option or warrant that is then outstanding, whether or 
not then exercisable or vested, shall be canceled by E/One, and each holder 
of a canceled option or warrant shall be entitled to receive from Sub at the 
same time as payment for Shares is made by Sub in connection with the Offer, 
in consideration for the cancellation of such option or warrant, an amount in 
cash equal to the product of (i) the number of Shares previously subject to 
such option or warrant, and (ii) the excess, if any, of the Offer Price over 
the exercise price per Share previously subject to such option or warrant, 
reduced by any applicable withholding.  Any options or warrants outstanding 
at the Effective Time shall be canceled.

affecting the title to or utility of any of the Material Properties and 
Assets, other than (i) such imperfections or irregularities of title,

      existing default or violation by E/One under any Contract or Lease and no 
      event has occurred which (whether with or without notice, lapse of time,

      except for such defaults as would not have a Material Adverse Effect.

                  (b)   E/One is not aware of any default by any other party to
      any Contract or Lease or of any event which (whether with or without

      Lease, except for such defaults as would not have a Material Adverse 
      Effect.

           liability for penalties or damages, whether liquidated, direct, 
           indirect, incidental or consequential, or

Laws.

under Environmental Laws in connection with the construction, ownership or 
operation of those assets and the businesses.  E/One is not aware of and has 
not received notice of any past, present or anticipated future events, 
conditions, activities, investigation, studies, plans or proposals that 
(a) would interfere with or prevent compliance by E/One with any

or otherwise form the basis of a claim, action, suit, proceeding, hearing or 
investigation, involving E/One and related in any way to Hazardous Substances

investigation, remedial, removal or other response costs, natural resources 
damages or other damages or for any other claims (including administrative 
orders) arising out of the release or threatened release of, or exposure to, 
any Hazardous Substance and no basis exists for any such liability.  E/One

release or threatened release of, or exposure to, any Hazardous Substance.

      representation have been raised or are threatened with respect to

      on E/One and no arbitration proceeding arising out of or under any 
      collective bargaining agreement is pending and to E/One's best knowledge

<PAGE>

                  (j)   There are no pending claims, and to E/One's best
      knowledge, no threatened claims by or on behalf of any of the employees of
      E/One under any federal, state or local labor or employment laws or 
      regulations.

      4.16  EMPLOYEE BENEFITS.  The Disclosure Schedule lists all pension, 
retirement, profit sharing, deferred compensation, bonus, commission, 
incentive, life insurance, health and disability insurance, hospitalization, 
and all other employee benefit plans or arrangements (including, without 
limitation, any contracts or agreements with trustees, insurance companies or 
others relating to any such employee benefit plans or arrangements) 
established, maintained, or contributed to by E/One that are currently in 
effect or that have been terminated within the past twelve months, and 
complete and accurate copies of all those plans or arrangements have been 
provided to PCC.  The employee pension and employee welfare benefit plans 
(within the meaning of Sections 3(1) and 3(2) of the Employee Retirement 
Income Security Act of 1974, as amended (ERISA)) established and maintained 
by E/One that are subject to ERISA are listed separately as ERISA Plans on 
the Disclosure Schedule (the ERISA Plans). The ERISA Plans comply in all 
material respects with the applicable requirements of ERISA and any other 
applicable laws and regulations.  With respect to ERISA Plans intended to 
qualify under Section 401(a) of the Code, E/One has received from the 
Internal Revenue Service (IRS) a favorable determination for each of the 
ERISA Plans that each of the ERISA Plans is qualified.  There has been no 
event subsequent to that determination of which E/One has received notice 
from IRS or has otherwise become aware  that has adversely affected the tax 
qualified status of the ERISA Plans or the exemption of the related trusts.  
As to any such ERISA Plan that has been terminated, any legally-required 
notices to employees and to the Pension Benefit Guaranty Corporation (if 
applicable) have been provided as required, all other legally-required 
actions have been taken to accomplish the termination, and a favorable IRS 
determination letter has been requested with respect to such termination.  In 
response to any such request for a determination letter on plan termination, 
a favorable letter has been received from the IRS or, if the requested 
favorable letter has not yet been received, there has been no event or 
absence of a necessary action that would prevent the issuance of a favorable 
determination letter on the termination in due course.  No accumulated 
funding deficiency as defined in Section 302(a)(2) of ERISA or Section 
412(a) of the Code exists, with respect to any of the ERISA Plans. Neither 
E/One nor a controlled group of corporations of which E/One is a member have 
any actual or potential withdrawal liability, as defined in Section 4201 
and related provisions of ERISA.  To the knowledge of E/One, none of the 
ERISA Plans, its related trusts or any trustee, investment manager or 
administrator thereof has engaged in a nonexempt prohibited transaction, as 
such term is defined in Section 406 of ERISA and Section 4975 of the Code.  
There are not and have not been any excess deferrals or excess 
contributions as defined in Code Sections 401(k)(8)(B) and 402(g)(2)(a) 
under any ERISA Plan that have not been corrected. Each ERISA Plan is, and to 
the knowledge of E/One has been, operated and administered in all material 
respects in conformance with the requirements of all applicable laws and 
regulations, whether or not the ERISA Plan documents have been amended to 
reflect such requirements. Except as set forth in the Disclosure Schedule, 
E/One has no obligation of any kind (whether under the terms of the ERISA 
Plans or under any understanding with employees) to make payments under, or 
to pay contributions to, any plan, agreement, or


                                       19
<PAGE>

other arrangement for deferred compensation of employees, whether or not tax 
qualified, including, without limitation, a single employer tax qualified 
plan, a tax qualified plan of a controlled group of corporations, a 
multi-employer pension plan, a nonqualified deferred compensation plan or an 
individual employment or compensation agreement, or any commitment to provide 
medical benefits to retirees.

      4.17  ABSENCE OF CERTAIN CHANGES OR EVENTS.  Except as disclosed in the 
Disclosure Schedule, since December 31, 1997, there has not been:

                  (a)   Any event, occurrence, development, or state of
      circumstances or facts which could reasonably be expected to result in a 
      Material Adverse Effect on the business, results of operations, financial
      position, assets, or properties of E/One;

                  (b)   Any damage, destruction, or casualty loss, whether

      the rate or terms of compensation payable or to become payable by E/One to
      its directors, officers, or key employees; any increase in the rate or 
      terms of any bonus, insurance, pension, or other employee benefit plan, 
      payment, or arrangement made to, for or with any such directors, officers,
      or key employees; any special bonus or remuneration paid; or any written 
      employment or change of control contract executed or amended;

                  (d)   Any amendment to E/One's Articles of Incorporation or

      expenditure or capital financing or any amendment, modification, or 
      termination of any existing agreement, commitment, or transaction) by 
      E/One, except agreements, commitments, or transactions in the ordinary 
      course of business and consistent with past practices or as expressly 
      contemplated in this Agreement;

                  (e)   Any direct or indirect declaration, setting aside, or
      payment of any dividend or other distribution (whether in cash, stock, 
      property, or any combination thereof) in respect of the common stock of 
      E/One, or any direct or indirect repurchase, redemption, or other 
      acquisition by E/One of any shares of its stock;

                  (f)   Any issuance or sale of any stock of E/One (other than
      issuances pursuant to the exercise of options or warrants outstanding on
      February 24, 1998) or any issuance or granting of any option, warrant, or 
      right to purchase any stock of E/One (other than options and warrants 
      granted on or before December 31, 1997) or any commitment to do any of 
      the foregoing;

<PAGE>

                  (g)   Any conduct of business that is outside the ordinary
      course of business or not substantially in the manner that E/One has

Proposal (as defined below).  Unless this Agreement has been terminated in 
accordance with its terms, and provided that neither PCC nor Sub is in 
material violation of this Agreement, E/One will not authorize or permit any 
of its officers, directors, or employees or any investment banker, financial 
advisor, attorney, accountant, or other representative retained by it to 
(i) solicit, initiate, or encourage (including by way of furnishing

any inquiries or the making of any proposal that constitutes, or may

in any discussions or negotiations regarding any Takeover Proposal; PROVIDED, 
HOWEVER, that, if at any time before the Effective Time, the Board of 
Directors of E/One determines in good faith, after consultation with counsel, 
that it is necessary to do so in order to comply with its fiduciary duties to 
E/One's stockholders under applicable law, E/One may, in response to an 
unsolicited Takeover Proposal, and subject to compliance with Section 6.2.3, 
(x) furnish information with respect to E/One to any Person pursuant to a 
confidentiality agreement in substantially the same form entered into between 
E/One and PCC and (y) participate in discussions and negotiations regarding 
such Takeover Proposal.  Without limiting the foregoing, it is understood 
that any violation of the restrictions set forth in the preceding sentence by 
any director or executive officer of E/One or any investment banker, 
financial advisor, attorney, accountant, or other representative of E/One 
will be deemed to be a breach of this Section 6.2.1 by E/One.  For purposes

business combination, sale of substantially all the assets, recapitalization, 
liquidation, dissolution or similar transaction involving E/One, other than

contemplated by this Agreement, or any other transaction the consummation of 
which could reasonably be expected to impede, interfere with, prevent, or 
materially delay the Offer or the Merger or that could reasonably be expected 
to dilute materially the benefits to PCC of the transactions contemplated by 
this Agreement.

            6.2.2 Except as set forth in this Section 6.2.2, and unless this 
Agreement has been terminated in accordance with its terms, and provided that 
neither PCC nor Sub is in material violation of this Agreement, neither the 
Board of Directors of E/One nor any committee thereof will (i) withdraw or 
modify, or propose to withdraw or modify, in a manner adverse to PCC, the 
approval or recommendation by such Board of Directors or such committee of 
this Agreement, the Offer or the Merger; (ii) approve or recommend, or 
propose to approve or recommend, any Takeover Proposal; or (iii) cause E/One 
to enter into any agreement with respect to any Takeover Proposal.  
Notwithstanding the foregoing, in the event that before the Effective Time 
the Board of Directors of E/One determines in good faith, after consultation 
with counsel, that it is necessary to do so in order to comply with its 
fiduciary duties to E/One's stockholders under applicable law, the Board of 
Directors of E/One may withdraw or modify its approval or recommendation of 
this Agreement, the Offer or the Merger, approve or recommend a Superior 
Proposal (as defined below), or cause E/One to enter into an agreement with 
respect to a Superior Proposal, but in each case only at a time that is after 
the second business day following PCC's receipt of written notice (a Notice 
of Superior Proposal) advising PCC that the Board of Directors of E/One has 
received a Superior Proposal, specifying the material terms and conditions of 
such Superior Proposal and identifying the Person making such Superior 
Proposal and that E/One has elected to terminate this Agreement pursuant to 
Section 6.2.2 of this Agreement.  In addition, if E/One therefter proposes to 
enter into an agreement with respect to any Takeover Proposal, it will within 
10 days after agreeing to the Takeover Proposal, pay, or cause to be paid, to 
PCC the Termination Fee (as such terms are defined in this Agreement) 
pursuant to and to the extent required in Section 8.5.3 of this Agreement.  
For purposes of this Agreement, a Superior Proposal means any bona fide 
Takeover Proposal to acquire, directly or indirectly, for consideration 
consisting of cash and/or securities, more than 50 percent of the shares of 
E/One Common Stock then outstanding or all or substantially all the assets of 
E/One and otherwise on terms which the Board of Directors of E/One determines 
in its good faith judgment (after consultation with The Nassau Group, Inc. or 
another financial advisor of nationally recognized reputation) to be more 
favorable to E/One's stockholders than the Offer and the Merger.

            6.2.3 In addition to the obligations of E/One set forth in 
Sections 6.2.1 and 6.2.2, E/One will within 48 hours but before responding to 
the request for information or Takeover Proposal,  advise PCC orally and in 
writing of any request for information or of any Takeover Proposal, or any 
inquiry with respect to or that could lead to any Takeover Proposal, the 
material terms and conditions of such request, Takeover Proposal, or inquiry 
and the identity of the Person making such request, Takeover Proposal, or 
inquiry.  E/One will keep PCC fully informed of the status and details 
(including amendments or proposed amendments) of any such request, Takeover 
Proposal or inquiry, subject to any requirements necessary to comply with its 
fiduciary duties to E/One Stockholders under applicable law.

            6.2.4 Nothing contained in Section 6.2 will prohibit E/One from 
making any disclosure to E/One's stockholders if, in the opinion of the Board 
of Directors of E/One, after consultation with counsel, failure so to 
disclose would be inconsistent with its fiduciary duties to E/One's 
stockholders under applicable law; PROVIDED, HOWEVER, neither E/One nor its 
Board of Directors nor any committee thereof will (except as permitted by 
Section 6.2.2), withdraw or modify, or propose to withdraw or modify, its 
position with respect to the Offer or the Merger or approve or recommend, or 
propose to approve or recommend, a Takeover Proposal.

      6.3   ACCESS.  For the period up to and including the Closing Date, 
E/One will provide, and cause each E/One Entity other than E/One to provide, 
to PCC and its authorized agents reasonable access to all of each E/One 
Entity's physical assets, facilities, financial information, production 
records, contracts and other corporate records and documents as PCC deems 
reasonably necessary, provided that such activities do not unreasonably 
interfere with or hinder the business or operation of E/One.  PCC will have 
reasonable access during normal working hours to all E/One Entity's premises, 
properties, and facilities and will be allowed to meet with each E/One 
Entity's management personnel, employees, and any outside consultants of the 
E/One Entities, including without limitation auditors and accountants, 
investment and other bankers, tax and financial advisors, and environmental 
consultants.  In addition, E/One will exercise its best efforts to make 
available to PCC any items and materials reasonably requested by PCC.  
However, no investigation by PCC or any of its authorized representatives 
before or after the date of this Agreement will effect any representation, 
warranty, or closing condition of any party to this Agreement.

      6.4   HART SCOTT RODINO.  Each of E/One and PCC will within five days 
after executing this Agreement prepare and file with the Federal Trade 
Commission (the FTC) and the Department of Justice (the DOJ) the 
premerger notification form required under the Hart Scott Rodino Antitrust 
Improvements Act (the HSR Act) and a request for early termination of the 
waiting period.  The parties will further (i) discuss with each other any 
comments the reviewing party may have; (ii) cooperate with each other in 
connection with such filings, which cooperation will include, but not be 
limited to, furnishing the other with such information or documents as may be 
reasonably required in connection with such filings; (iii) promptly file 
after any request by the FTC or the DOJ any appropriate information or 
documents so requested by the FTC or the DOJ; and (iv) notify each other of 
any other communications with the FTC or the DOJ that relate to the 
transactions contemplated by this Agreement and, to the extent appropriate, 
permit the other to participate in any conferences with the FTC or the DOJ.  
The parties will use best efforts to accelerate and obtain HSR Act clearance. 
Each of E/One and PCC will pay its own expenses in connection with the 
preparation of the premerger notification form.

      6.5   OTHER GOVERNMENT CONSENTS.  Promptly following the execution of 
this Agreement, the parties will proceed to prepare and file with the 
appropriate Governmental Entities any requests for approval or waiver (in 
addition to those specifically described above), if any, that are required 
from Governmental Entities in connection with the transactions contemplated 
by this Agreement, and the parties will diligently and expeditiously 
prosecute and cooperate fully in the 


                                      30
<PAGE>

prosecution of such requests for approval or waiver and all proceedings 
necessary to secure such approvals and waivers.

      6.6   BEST EFFORTS; NO INCONSISTENT ACTION.  Subject to the terms and 
conditions hereof, and to the fiduciary duties of the E/One Board under 
applicable law as advised by counsel, each party will use its best efforts to 
effect the transactions contemplated by this Agreement and to fulfill the 
conditions to the obligations of the opposing parties set forth in Article 7 
of this Agreement.  No party will take any action inconsistent with its 
obligations under this Agreement or that could hinder or delay the 
consummation of the transactions contemplated by this Agreement without legal 
authority or basis, except that nothing in this Section 6.6 will limit the 
rights of the parties under Article 7 of this Agreement.

      6.7   CHANGED CIRCUMSTANCES.  Each of E/One and PCC will notify the 
other party promptly of any fact or occurrence between the date of this 
Agreement and the Closing Date of which it becomes aware which makes any of 
its representations contained in this Agreement untrue or causes any breach 
of its obligations under this Agreement.

      6.8   FEES AND EXPENSES.

            All fees and expenses incurred in connection with the Offer and 
Merger, this Agreement, and the transactions contemplated by this Agreement 
will be paid by the party incurring such fees or expenses, whether or not the 
Offer or the Merger is consummated.

      6.9   PRESS RELEASES.  No press releases or other public announcements 
or disclosure of information to any third party concerning the transactions 
contemplated by this Agreement may be made by any of the parties without the 
prior written consent of each of the other parties, which consent will not be 
unreasonably withheld; PROVIDED, HOWEVER, that nothing in this provision will 
prevent a party from making such releases or announcements as are necessary 
for a party to satisfy its legal obligations or the requirements of the New 
York Stock Exchange or NASDAQ NMS, but in any such case the affected party 
will promptly notify the other parties.

                                   ARTICLE 7

in a form satisfactory to each of E/One, Sub, and PCC in its reasonable 
discretion, and the waiting period under the HSR Act will have expired or 
been terminated early.

vote of the holders of at least 66 2/3 percent of the issued and outstanding
Shares of E/One Common Stock (Stockholder Approval).

      7.3   NO PROHIBITIONS.  There has not been promulgated or issued a law,

or restricts the consummation of the Merger.

      7.4   NO SUITS.  No action, suit or other proceeding is pending against 
any party to this Agreement to prohibit, restrain, enjoin, restrict or 
otherwise prevent the consummation of the transactions contemplated by this

fails to purchase any Shares validly tendered and not withdrawn pursuant to 
the Offer.

                                   ARTICLE 8

                                  TERMINATION

terminated without further liability at any time before the Closing Date:

            8.1.2 INJUNCTION OR RESTRAINT.  By either PCC or E/One, if any 
Governmental Entity has promulgated or issued a law, statute, rule, 
regulation, decree, order, injunction, or ruling or taken any other action

under the HSR Act is not received within sixty (60) days after the filing of 
the premerger notification and report form.

            8.1.3 FAILURE OF OFFER.  By PCC or E/One if the Offer is 
terminated or expires in accordance with its terms as the result of the 
failure of any of the Offer Conditions without Sub having purchased any

                                      32
<PAGE>

under this Section 8.1.3 is not available to any party whose failure to 
perform any of its covenants or agreements under this Agreement results in 
the failure of any condition.

      8.2   TERMINATION BY PCC.  PCC, if not then in default, may terminate 
this Agreement at any time before the Closing Date upon written notice to 
E/One of the occurrence of any of the following:

            8.2.1 BREACH BY E/ONE.  A breach by E/One of one or more of its 
representations or warranties or a default in the observance or performance 
of one or more of its covenants or agreements under this Agreement, which 
breach or default is not cured within ten (10) days after E/One has notice 
thereof, except for breaches and defaults which, individually or in the 
aggregate, would not have a Combined Material Adverse Effect or materially 
impair the ability of the parties to consummate the transactions contemplated 
by the Agreement.

            8.2.2 WITHDRAWAL OF E/ONE BOARD APPROVAL.  If (i) the Board of 
Directors of E/One or any committee thereof has withdrawn or modified in a 
manner adverse to PCC or Sub its approval or recommendation of the Offer or

E/One has entered into a definitive agreement with respect to any Superior 
Proposal in accordance with Section 6.2.2 of this Agreement.

      8.3   TERMINATION BY E/ONE.  E/One, if not then in default, may 
terminate this Agreement at any time before the Closing Date upon written 
notice to PCC of the occurrence of any of the following:

            8.3.1 BREACH BY PCC OR SUB.  A breach by PCC or Sub of one or 
more of its representations or warranties or a default in the observance or 
performance of one or more of its covenants or agreements under this 
Agreement, which breach or default is not cured within ten (10) days after

individually or in the aggregate, would not have a Combined Material Adverse 
Effect or materially impair the ability of the parties to consummate the 
transactions contemplated by the Agreement.

            8.3.2 LEGAL REQUIREMENTS OF DIRECTORS.  If E/One determines in 
accordance with Section 6.2.2 after consultation with legal counsel that it

it has complied with the notice provisions and other requirements set forth 
in Section 6.22 of this Agreement, including the notice provisions and 
payment provisions thereof.

      8.4   PROCEDURE; EFFECT OF TERMINATION.  If either PCC or E/One elects 
to terminate this Agreement pursuant to this Article 8, the terminating party 
will promptly give written notice thereof to the other party.  In the event 
of termination pursuant to this Article 8, the parties will be released from 
all liabilities and obligations under this Agreement, other than the 
obligations under Section 6.8 and Section 8.5 and except that nothing herein 
shall relieve any party from 


                                      33
<PAGE>

liability for damages to the extent arising from a breach of this Agreement 
before termination. The Confidentiality Agreement dated November 25, 1997 
between E/One and PCC (the Confidentiality Agreement) is and will remain 
until the Effective Time in full force and effect and will survive any 
termination of this Agreement.

      8.5   BREAK-UP FEES.

            8.5.2 WRONGFUL TERMINATION BY E/ONE.  In the event that the Offer

            8.5.3 TAKEOVER PROPOSAL.  In the event that E/One determines

Agreement in order for its directors to comply with their fiduciary duties 
under applicable Legal Requirements (such Legal Requirements shall be

8.3.2 of this Agreement and E/One agrees to a Takeover Proposal within 270 
days of the date of termination of this Agreement, or agrees to a Superior 
Proposal within one year of the date of termination of this Agreement, then 
E/One shall pay or cause to be paid to PCC an amount equal to Three Million 
Dollars ($3.0 million) in cash (the Termination Fee).
 
            8.5.4 FAILURE OF CONDITION.  Neither PCC nor E/One shall be 
treated as terminating this Agreement in breach of this Agreement if the

                              GENERAL PROVISIONS

      9.1   SURVIVAL OF REPRESENTATIONS, WARRANTIES AND AGREEMENTS.  The 
Agreements in Article 2 and Article 9 shall survive the Effective Time.  The 
remainder of the representations, warranties, and agreement in this Agreement 
or in any instrument delivered pursuant to this Agreement will not survive

                                      34
<PAGE>

termination of this Agreement pursuant to Section 8.1. This Section 9.1 will

and take any additional action reasonably required to fully implement this 
Agreement.

that no such assignment shall relieve the assigning party of its obligations 
hereunder if the assignee does not perform the obligations.

      9.5   BINDING EFFECT; NO THIRD PARTY BENEFIT.  This Agreement will

this Agreement or any transaction contemplated by it.

      9.6   WAIVER.  Failure of any party at any time to require performance 
of any provision of this Agreement will not limit such party's right to 
enforce such provision, nor will any waiver of any breach of any provision of 
this Agreement constitute a waiver of any succeeding breach of such provision 
or a waiver of such provision itself.  Any waiver of any provision of this 
Agreement will be effective only if set forth in writing and signed by the 
party to be bound.

      9.7   GOVERNING LAW.  This Agreement will be governed and construed in 
accordance with the laws of the State of New York.

      9.8   SEVERABILITY.  If any term or provision of this Agreement or the

invalid or unenforceable, the remainder of this Agreement and the application 
of such term or provision to Persons or circumstances other than those as to 
which it is held invalid or unenforceable will not be affected thereby, and 
each term or provision of this Agreement will be valid and enforceable to the 
fullest extent permitted by law.

original counterpart to be transmitted by courier service to the other 
parties.

by the written agreement of E/One, Sub, and PCC.  This Agreement may not be

limitation, the approval and adoption of this Agreement and the Offer and the 
Merger; or (iv) requires divestiture by PCC or Sub of any material portion of 
the Shares;

            (b)   there shall have been any action taken, or any statute,

respect of banks in the United States, (iv) any limitation (whether or not 
mandatory) by any governmental authority on the general extension of credit

any such condition or may be waived by Sub or PCC in whole or in part at any 
time and from time to time in its sole discretion.  The failure by PCC or Sub 
at any time to exercise any of the foregoing rights shall not be deemed a 
waiver of any such right; the waiver of any such right with respect to 
particular facts and other circumstances shall not be deemed a waiver with 
respect to any other facts and circumstances; and each such right shall be 
deemed an ongoing right that may be asserted at any time and from time to 
time.

                                STOCKHOLDER AGREEMENT


     STOCKHOLDER AGREEMENT dated as of February 24, 1998 among PRECISION
CASTPARTS CORP., an Oregon corporation ("PCC"), EOC ACQUISITION CORPORATION, a
New York corporation and a direct or indirect wholly owned subsidiary of PCC
("Sub"), and the other parties identified on SCHEDULE A hereto (each, a
"Stockholder").

     WHEREAS, each Stockholder desires that Environment One Corporation, a New
York corporation (the "Company"), PCC and Sub enter into an Agreement and Plan
of Merger dated as of the date hereof (as the same may be amended or
supplemented, the "Merger Agreement") with respect to the merger of Sub with and
into the Company (the "Merger"); and

     WHEREAS, each Stockholder is executing this Agreement as an inducement to
PCC and Sub to enter into and execute the Merger Agreement.

     NOW, THEREFORE, in consideration of the execution and delivery by PCC and
Sub of the Merger Agreement and the mutual covenants, conditions and agreements
contained herein and therein, the parties agree as follows:

     SECTION 1.  REPRESENTATIONS AND WARRANTIES.  Each Stockholder severally,
and not jointly, represents and warrants to PCC and Sub as follows:

     (a)  Such Stockholder is the record or beneficial owner of, or has the
power to dispose, the number of shares of Common Stock of the Company (the
"Company Common Stock"), and holds options for shares of Company Common Stock,
each as set forth opposite such Stockholder's name in SCHEDULE A hereto (as may
be adjusted from time to time pursuant to  Section 4, such Stockholder's
"Shares").  Except for such Stockholder's Shares, such Stockholder is not the
record or beneficial owner of any shares of Company Common Stock.  Any of such
Shares which are described on SCHEDULE A as option shares shall be deemed
"Option Shares" for the purposes of this Agreement.  All other shares shall be
deemed "Owned Shares."  Any Option Shares which are exercised prior to the
termination of this Agreement shall be deemed to be "Owned Shares."

     (b)  This Agreement has been executed and delivered by such Stockholder and
constitutes the legal, valid and binding obligation of such Stockholder,
enforceable against such Stockholder in accordance with its terms, except (i) as
limited by applicable bankruptcy, insolvency, reorganization, moratorium and
other laws of general application affecting enforcement of creditors' rights
generally, and (ii) as limited by laws relating to the availability of specific
performance, injunctive relief or other equitable remedies. To the best of
Stockholder's knowledge, neither the execution and delivery of this Agreement
nor the consummation by such Stockholder of the transactions contemplated hereby
will result in a


<PAGE>

violation of, or a default under, or conflict with, any contract, trust,
commitment, agreement, understanding, arrangement or restriction of any kind to
which such Stockholder is a party or bound or to which such Stockholder's Shares
are subject.

     (c)  Such Stockholder's Owned Shares and the certificates representing such
Owned Shares are now and at all times during the term hereof will be held by
such Stockholder, or by a nominee or custodian for the benefit of such
Stockholder, free and clear of all liens, claims, security interests, proxies,
voting trusts or agreements, understandings or arrangements or any other
encumbrances whatsoever, except for any such encumbrances arising hereunder.

     (d)  Such Stockholder understands and acknowledges that PCC is entering
into, and causing Sub to enter into, the Merger Agreement in reliance upon such
Stockholder's execution and delivery of this Agreement.

     SECTION 2.  PURCHASE AND SALE OF SHARES.  So long as the Offer Price in the
Offer for all Shares is not less than $15.25 in cash (net to the seller), each
Stockholder hereby severally agrees that he will tender or cause to be tendered
his Shares into the Offer prior to the expiration of the Offer and that he will
not withdraw any Shares so tendered (it being understood that the obligation
contained in this sentence is unconditional).  In addition, each Stockholder
hereby severally agrees to sell to Sub, and Sub hereby agrees to purchase, all
such Stockholder's Owned Shares at a price per Share equal to the Offer Price,
provided that such obligations to purchase and sell are both subject to (i) Sub
having accepted Shares for payment under the Offer and the Minimum Condition (as
defined in the Merger Agreement) having been satisfied, and (ii) the expiration
or termination of any applicable waiting period under the HSR Act.

     SECTION 3.  COVENANTS.  Each Stockholder severally, and not jointly, agrees
with, and covenants to, PCC and Sub as follows:  such Stockholder shall not,
except as contemplated by the terms of this Agreement, during the term of this
Agreement, (i) transfer (which term shall include, without limitation, for the
purposes of this Agreement, any sale, gift, pledge or other disposition), or
consent to any transfer of, any or all of such Stockholder's Shares or any
interest therein, (ii) enter into any contract, option or other agreement or
understanding with respect to any transfer of any or all of such Shares or any
interest therein, (iii) grant any proxy, power-of-attorney or other
authorization or consent in or with respect to such Shares other than in
connection with a meeting to approve the Merger or the annual meeting of
Stockholders of the Company, (iv) deposit such Shares into a voting trust or
enter into a voting agreement or arrangement with respect to such Shares, or (v)
take any other action that would in any way restrict, limit or interfere with
the performance of its obligations hereunder or the transactions contemplated
hereby; provided that each Stockholder shall be entitled to transfer all or any
portion of such Shareholder's Shares to any person or entity which agrees in
writing to be bound by the provisions of this Agreement.


                                          2
<PAGE>

     SECTION 4.  CERTAIN EVENTS.  Each Stockholder agrees that this Agreement
and the obligations hereunder shall attach to such Stockholder's Shares and
shall be binding upon any person or entity to which legal or beneficial
ownership of such Shares shall pass, whether by operation of law or otherwise,
including without limitation such Stockholder's heirs, guardians, administrators
or successors.  In the event of any stock split, stock dividend, merger,
reorganization, recapitalization or other change in the capital structure of the
Company affecting the Company Common Stock, or the acquisition of additional
shares of Company Common Stock or other securities or rights of the Company by
any Stockholder, the number of Owned Shares and Option Shares listed on SCHEDULE
A beside the name of such Stockholder shall be adjusted appropriately and this
Agreement and the obligations hereunder shall attach to any additional shares of
Company Common Stock or other securities or rights of the Company issued to or
acquired by such Stockholder.

     SECTION 5.  TRANSFER.  Each Stockholder agrees with and covenants to PCC
that such Stockholder shall not request that the Company register the transfer
(booked as entry or otherwise) of any certificated or uncertificated interest
representing any of the securities of the Company, unless such transfer is made
in compliance with this Agreement.

     SECTION 6.  VOIDABILITY.  If prior to the execution hereof, the Board of
Directors of the Company shall not have duly and validly authorized and approved
by all necessary corporate action the acquisition of Company Common Stock by PCC
and Sub and other transactions contemplated by this Agreement and the Merger
Agreement, so that by the execution and delivery hereof PCC or Sub would become,
or could reasonably be expected to become, an "interested stockholder" with whom
the Company would be prevented for any period pursuant to Section 912 of the
NYBCL from engaging in any "business combination" (as such terms are defined in
Section 912 of the NYBCL), then this Agreement shall be void and unenforceable
until such time as such authorization and approval shall have been duly and
validly obtained.

     SECTION 7.  STOCKHOLDER CAPACITY.  No person executing this Agreement who
is a director or officer of the Company makes any agreement or understanding
herein in his capacity as such director or officer.  Each Stockholder signs
solely in his capacity as the record holder and beneficial owner of such
Stockholder's Shares and nothing herein shall limit or affect any actions taken
by a Stockholder in his capacity as an officer or director for the Company to
the extent specifically permitted by the Merger Agreement, including the
fiduciary duties of officers and directors in accordance with New York law.

     SECTION 8.  FURTHER ASSURANCES.  Each Stockholder shall, upon request of
PCC or Sub, execute and deliver any additional documents and take such further
actions as may reasonably be deemed by PCC or Sub to be necessary or desirable
to carry out the provisions hereof.

     SECTION 9.  TERMINATION.  This Agreement, and all rights and obligations of
the parties hereunder, shall terminate upon the earlier of (a) the date upon
which the Merger


                                          3
<PAGE>

Agreement  is terminated by the Company, PCC or Sub for any reason in accordance
with its terms, (b) the date that PCC or Sub shall have purchased and paid for
the Shares of each Stockholder pursuant to Section 2, or (c) May 30, 1998.

     SECTION 10. MISCELLANEOUS.

     (a)  Capitalized terms used and not otherwise defined in this Agreement
shall have the respective meanings assigned to such terms in the Merger
Agreement.

     (b)  All notices, requests, claims, demands and other communications under
this Agreement shall be in writing and shall be deemed given if delivered
personally or sent by overnight courier (providing proof of delivery) to the
parties at the following addresses (or such other address for a party as shall
be specified by like notice): (i) if to PCC or Sub, to the address set forth in
Section 9.13 of the Merger Agreement, and (ii) if to a Stockholder, to the
address set forth on SCHEDULE A hereto, or such other address as may be
specified in writing by such Stockholder.

     (c)  The headings contained in this Agreement are for reference purposes
only and shall not affect in any way the meaning or interpretation of this
Agreement.

     (d)  This Agreement may be executed in two or more counterparts, all of
which shall be considered one and the same agreement, and shall become effective
(even without the signature of any other Stockholder) as to any Stockholder when
one or more counterparts have been signed by each of PCC, Sub and such
Stockholder and delivered to PCC, Sub and such Stockholder.

     (e)  This Agreement (including the documents and instruments referred to
herein) constitutes the entire agreement, and supersedes all prior agreements
and understandings, both written and oral, among the parties with respect to the
subject matter hereof.

     (f)  This Agreement shall be governed by, and construed in accordance with,
the laws of the State of New York, regardless of the laws that might otherwise
govern under applicable principles of conflicts or laws thereof.

     (g)  Neither this Agreement nor any of the rights, interests or obligations
under this Agreement shall be assigned, in whole or in party, by operation of
law or otherwise, by any of the parties without the prior written consent of the
other parties, except by laws of descent.  Any assignment in violation of the
foregoing shall be void.

     (h)  If any term, provision, covenant or restriction herein, or the
application thereof to any circumstance, shall, to any event, be held by a court
of competent jurisdiction to be invalid, void or unenforceable, the remainder of
the terms, provisions, covenants and restrictions herein and the application
thereof to any other circumstances, shall remain in full


                                          4
<PAGE>

force and effect, shall not in any way be affected, impaired or invalidated, and
shall be enforced to the fullest extent permitted by law.

               Re:  Confidentiality Agreement
                    -------------------------

Dear Bill:

          You have expressed interest in a possible transaction (the 
"Transaction") involving Environment One Corporation (the "Company") and have 
requested certain information concerning the Company. As a condition of 
furnishing you with such information, including, without limitation, certain 
non-public confidential information and proprietary business practices and 
concepts concerning the Company's business, properties, finances, affairs and 
technology, whether or not such information is in writing or given orally, 
the Company is requiring that you agree, as set forth below, to treat 
confidentially such information, any other information that the Company, The 
Nassau Group, Inc. or the Company's affiliates, advisors, representatives, 
employees or agents (together with The Nassau Group, Inc. the "Company 
Parties") furnish to you and any notes, analyses, compilations, studies, 
interpretations, or other documents prepared by you or your representatives 
(as defined below) that contain or are based upon such information 
(collectively, the "Evaluation Material")

          For purposes of this letter agreement, any Evaluation Material 
furnished to you by an officer or employee, or an agent or advisor to the 
Company, regardless of the date furnished and regardless of the capacity in 
which such officer, employee, agent or advisor purports to be acting, shall 
be deemed Evaluation Material furnished by or on behalf of the Company. You 
agree, on your behalf and on behalf of your Representatives, (i) that the 
Evaluation Material will be used only in connection with, and to assist in 
your evaluation of, the Transaction, (ii) that all Evaluation Material will 
be kept strictly confidential by you and your Representatives, and (iii) that 
all information furnished by the Company or the Company Parties pursuant to 
this Agreement will remain the exclusive property of the Company and that you 
and your Representatives will hold all of such information in confidence for 
the exclusive benefit of the Company (except that such information may be 
used by you for the purposes contemplated herein). You specifically agree 
that Evaluation Material shall not be used, directly or indirectly to compete 
with or emulate the Company's business. You agree to transmit the Evaluation 
Material only to those of your directors, officers, employees, affiliates, 
agents, attorneys, accountants, advisors, financing sources or partners, and 
others ("Representatives") who need to know such information for the purpose 
of assisting you in your evaluation of the Transaction and who shall (i) be 
advised by you of this Agreement and (ii) agree to be bound by the provisions 
of this Agreement. You and your Representatives shall not, except as 
described in the previous sentence or as hereinafter provided, disclose 
Evaluation Material or any of the terms, conditions, or other facts with 
respect to the possible Transaction to others without the prior written 
consent of the Company. Without limiting the foregoing, you and your 
Representatives agree to keep even existence of discussions between you and 
the Company strictly confidential. You shall be responsible for any such 
breach of this Agreement by you and/or any of your Representatives.

                                        - 1 -

Mr. William C. McCormick
Precision Castparts Corporation

          If you conduct any portion of your investigation on premises made
available by the Company, you shall not remove Evaluation Material made
available by the Company from those premises without the Company's consent. If
you determine that you do not wish to proceed with a Transaction, you will so
notify the Company immediately.

          You further agree that any and all requests for Evaluation Material,
other communications regarding the possible Transaction, and requests for
additional information shall be made only to individuals designated to you in
writing by the Company and that, without the Company's prior written consent,
you will not initiate any contacts of any kind with the staff or employees of
the Company. Upon the Company's request, you will promptly identify in writing
each person or other entity to whom any part of the Evaluation Material is
disclosed.

          The Company and the Company Parties make no representation or
warranty, expressed or implied, as to the accuracy or completeness of any or all
of the Evaluation Material. The Company shall have no obligation to update any
Evaluation Material. The Company and Company Parties will have no liability for
actions taken by you or your Representatives in reliance on any information
provided by the Company or the Company Parties with respect to a possible
Transaction. Unless and until a definitive Transaction agreement between the
Company and you is executed and delivered, the Company will not have any legal
obligation of any kind by virtue of this Agreement or any other written or oral
expression with respect to the possible transaction.

          It is agreed that we may elect at any time to terminate further 
access to, and your review of, the Evaluation Material and that as soon as 
practicable after such termination, you will, upon the Company's request, 
return all Evaluation Material, but that such termination will not affect or 
eliminate your obligations and those of your Representatives by reason of 
this Agreement. It is further agreed that we shall not be obligated pursuant 
to this Agreement to disclose any particular confidential information or 
Evaluation Material.

          In the event that you or any of your Representatives are required 
(by oral questions, interrogatories, requests for information or document 
subpoena, or similar legal process) to disclose any of the Evaluation 
Material, you will provide the Company with prompt notice of such request(s) 
so that the Company may seek an appropriate protective order or other 
appropriate remedy and/or waive your compliance with the provisions of this 
Agreement. If in the absence of a protective order or other remedy or the 
receipt of a waiver by the Company, you or your Representatives are 
nonetheless, in the written opinion of counsel, legally compelled to disclose 
Evaluation Material to any tribunal or else stand liable for contempt or 
suffer other censure or penalty, you or your Representatives may, without 
liability hereunder, disclose to such tribunal only that portion of the 
Evaluation Material which such counsel advises you is legally required to be 
disclosed, provided that you exercise your best efforts to preserve the 
confidentiality of the Evaluation Material, including, without limitation, by 
cooperating with the Company to attain an appropriate protective order or 
other reliable assurance that confidential treatment will be accorded the 
Evaluation Material by such tribunal; provided, however, that after any such 
disclosure such disclosed information shall remain confidential and subject 
to the terms of the Agreement.

          In the event that the Transaction is not effected after you have 
been furnished with Evaluation Material, you will promptly upon the request 
of the Company (i) deliver to the Company all documents and other tangible 
media that contain or reflect information furnished by the Company or the

Company Parties (including all copies, reproductions, digests, abstracts,
analyses and notes) and that are in your or your Representatives' possession or
control and (ii) destroy all documents and other tangible media that contain or
reflect the Evaluation Material (including all copies, reproductions, digests,
abstracts, analyses and notes) in your possession or control, or your
Representatives' possessions or control, in each instance without retaining a
copy of any Evaluation Material (whether returned or destroyed pursuant to
clauses (i) or (ii) above), and will destroy any and all related computer
entries of any such Evaluation Material, without retaining a copy thereof.

          You further agree for a period of two years from the date hereof, that
you or your affiliates shall not solicit or hire any of the employees of the
Company who are employees of the Company during the period of your investigation
of the Company while they are still employed by the Company. Nothing in this
Agreement shall be construed as a grant by the Company of any right, title or
interest in the Evaluation Material except the right to use such Evaluation
Material for the purpose and to the extent set forth in this Agreement.

          The term Evaluation Material shall not include information that you 
demonstrate by clear and convincing evidence has (i) become or has been 
generally available to the public other than as a result of disclosure by 
you, your Representatives, or other improper means, (ii) was known by you, or 
was acquired by you without any known breach of a confidentiality obligation 
prior to its disclosure to you by the Company or its representatives, as 
evidenced by documentation or other physical evidence predating the date of 
this Agreement or (iii) has become available to you on a non-confidential 
basis from a source other than the Company or its representatives, provided, 
however, that such source was otherwise legally entitled to make such 
disclosure to you and you notify the Company of such acquisition within ten 
(10) days after the acquisition or, if the acquisition precedes disclosure by 
the Company, promptly upon such disclosure.

          You understand that a breach by you of this Agreement would cause
substantial and irreparable damage to the Company and that money would be an
inadequate remedy therefor. Accordingly, you acknowledge and agree that the
Company shall be entitled to any other available remedies to an injunction,
specific performance and/or equitable relief as a remedy for such breach.

          Each party represents and warrants to the other that (a) it has 
duly authorized, executed and delivered this Agreement, and (b) it has not 
entered and will not enter into any agreement inconsistent herewith. This 
Agreement (a) shall be governed by and construed in accordance with the laws 
of New York State, (b) shall be binding upon such parties, successors, 
assigns, legal representatives and (c) may not be amended, supplemented, 
terminated, or any provision herein waived except by written agreement of 
both parties hereto. The parties hereto agree that any dispute thereunder 
shall be submitted exclusively to the federal or appropriate New York State 
court having jurisdiction located in Schenectady County, New York, and the 
parties consent to the venue and jurisdiction of such courts. This Agreement 
represents the entire understanding between the parties with respect to the 
subject matter hereof. No contemporaneous or prior written or oral agreement 
shall be construed to alter, repeal or modify this Agreement and no consent 
to or waiver of any breach of or default under any provision of this 
Agreement shall be construed as a consent to or waiver of any other such 
breach or default. This Agreement may be executed in two or more 
counterparts, all of which together shall constitute a single instrument. In 
making proof of this Agreement, it shall not be necessary to produce or 
account for more than one fully executed counterpart.

     RE:  EMPLOYMENT AGREEMENT

Dear Steve:

     This Employment Agreement (this "Agreement") sets forth our agreement
concerning the terms of your employment by Environment One Corporation ("E/One"
or the "Company") following its acquisition by Precision Castparts Corp. ("PCC")
pursuant to an Agreement and Plan of Merger dated February 24, 1998 (the "Merger
Agreement"), to become effective on the Tender Offer Acceptance Date as defined
in the Merger Agreement (the "Effective Date").

1.   EMPLOYMENT OFFER.

     1.1  EMPLOYMENT.

          (a)  You will hold the position of CEO/President of E/One beginning on
the Effective Date and perform those duties as are generally associated with
such a position.  You will report to the President of PCC Flow Technologies,
Inc., and to the Board of Directors of E/One.  You also agree to perform such
acts and duties as the President of PCC Flow Technologies, Inc. or the Board of
Directors of E/One may reasonably direct, to comply with all reasonable
applicable policies and procedures of E/One and, as reasonably applicable, its
parent and affiliates, and to devote such time, energy and skill to your
assignment as the President of PCC Flow Technologies, Inc. considers reasonably
necessary for the performance of your duties, provided that you will not be
required to relocate from the Albany, New York area.

          (b)  Your employment with E/One will continue under this Agreement
through the date that is one (1) year from the Effective Date, unless earlier
terminated by you or E/One as expressly provided in paragraph 2.1, below.  Your
employment may continue beyond the one (1) year term of this Agreement, on an
at-will basis, by mutual


<PAGE>

Mr. Stephen V. Ardia

Page 2


agreement of you and E/One.  Your last day of employment with E/One is referred
to herein as your Separation Date.

     1.2  SALARY.

          During the term of this Agreement, you will be paid a base salary at
annual rate of $150,000, payable in installments on regular Company paydays,
subject to any salary increases approved by the Board of Directors of E/One and
the President of PCC Flow Technologies, Inc. consistent with the Company's
practice of considering salary increases in April of each year.

     1.3  BENEFITS.

          In addition to your base compensation, you will be entitled to
participate through December 31, 1998 in the E/One bonus plan as in effect
immediately prior to the Effective Date.  For the three-month period January 1,
1999 through March 28, 1999 you will be entitled to participate in a bonus
program similar to the E/One bonus program in effect for calendar year 1998,
except that bonus targets will be determined by the Company's Board of Directors
in its sole discretion and will be keyed to 1999 objectives established by the
Company's Board of Directors. You will also continue to receive the same or
comparable non-bonus employee benefits as provided by E/One to you during your
employment immediately prior to the Effective Date, provided that (i) the E/One
stock option plans will be eliminated, and (ii) the E/One Deferred Compensation
Plan will be amended to eliminate the E/One stock investment provisions and to
provide for alternate investment options. Amounts received under the bonus plan
in respect of calendar year 1998 will be eligible for deferral under the E/One
Deferred Compensation Plan, but no other future deferrals will be permitted
under that plan.  You will also be eligible to participate in PCC's stock option
and stock purchase programs in accordance with the terms of those programs.

2.   TERMINATION OF AGREEMENT.

     2.1  TERMINATION.  The term of this Agreement shall be as stated in
subparagraph 1.1(b) (the "natural expiration date"), unless terminated earlier
as follows:

          (a)  This Agreement may be terminated by you for any reason upon 30
days' written notice to E/One after the date that is three months after the
Effective Date.


<PAGE>

Mr. Stephen V. Ardia
February 24, 1998
Page 3


          (b)  This Agreement shall automatically terminate in the event of your
death or disability prior to the natural expiration date.  For purposes of this
Agreement, "disability" shall mean inability to perform all or substantially all
of your responsibilities for a period of more than six (6) months.

     2.2  Upon termination under Paragraph 2.1, you shall be entitled to receive
your base salary through the date of termination, payment for unused vacation
accrued through the date of termination, and no other compensation.

3.   CONFIDENTIALITY, NON-SOLICITATION AND NON-COMPETITION.

     3.1  PRESERVATION AND NON-USE OF CONFIDENTIAL INFORMATION.  You acknowledge
that you have a fiduciary duty as an officer and employee of the Company not to
discuss Confidential Information obtained during your employment with the
Company.  For purposes of this Agreement, "Confidential Information" means any
and all confidential or proprietary information concerning the Company or its
affiliates, joint venturers or other related entities (the "E/One Group"), the
disclosure of which could disadvantage the E/One Group.  Confidential
Information includes trade secrets as defined under the Uniform Trade Secrets
Act.

     You agree not to use Confidential Information, during the term of this
Agreement or after its termination, for any personal or business purpose, either
for your own benefit or that of any other person, corporation, government or
other entity.

     You also agree that you will not disclose or disseminate any Confidential
Information, directly or indirectly, at any time during the term of this
Agreement or after its termination, to any person, agency, or court unless
compelled to do so pursuant to legal process (E.G., a summons or subpoena) or
otherwise required by law and then only after providing the Company with prior
notice and a copy of the legal process.

     3.2  NON-SOLICITATION AND NON-COMPETITION.  You agree that you will not,
without the express written consent of the Board, for a period of one (1) year
following your Separation Date directly or indirectly (by yourself or in
conjunction with any other person, company or organization), solicit or divert
any employee, customer or vendor of the Company or any of its affiliates, joint
venturers or other related entities.  You further agree that you will not,
without the express written consent of the Board of Directors, for a period of
one (1) year following your Separation Date, directly or indirectly, accept


<PAGE>

Mr. Stephen V. Ardia

employment with any person or entity involved in, or enter into any business
relationship that involves, the business of manufacturing or selling low
pressure sewage systems or grinder pumps (including, but not limited to, as a
consultant, vendor, partner, officer or director).  The foregoing shall not
preclude your employment by a distributor of the Company's products in the case
of your voluntary termination of employment with the Company.  You specifically
acknowledge and agree that the terms of this provision are reasonable in every
respect and, in particular, because of the competitive and specialized nature of
the Company's business, that it is reasonable not to include any geographic
limitation in this provision.

4.   RETURN OF PROPERTY.

     On or before your Separation Date, except as agreed to by the Company, you
will return all property belonging to E/One, including, but not limited to, all
documents, business machines, computers, computer hardware and software
programs, computer data, telephones (cellular, mobile or otherwise), pagers,
keys, card keys, credit cards and other Company-owned property.

5.   ASSISTANCE IN DEFENSE OF LITIGATION OR CLAIMS.

     In the event E/One requests assistance during the period of one (1) year
following your Separation Date, you agree to provide reasonable assistance in
defense of ongoing or future litigation or claims about which you have knowledge
without additional compensation.  Thereafter, you agree to provide reasonable
assistance and will be paid for your assistance at an hourly rate equal to your
hourly equivalent rate of pay as of your Separation Date (for up to seven (7)
hours in one day) or per diem rate equal to eight (8) times your hourly
equivalent rate of pay as of your Separation Date (for more than seven (7) hours
in one day).  You will be reimbursed for any reasonable expenses incidental to
this assistance approved in advance by the Company.  The Company will reasonably
accommodate your scheduling needs.

6.   RIGHT TO CONSULT WITH ATTORNEY.

     You have the right to consult with an attorney or financial advisor at your
own expense regarding this Agreement.

7.   DISPUTE RESOLUTION.

     You agree that any dispute (1) concerning the interpretation or
construction of this Agreement, (2) arising from your employment with or
termination of employment from E/One, (3) relating to any compensation or
benefits you may claim, or (4) relating in any way to any claim by you for
reinstatement or reemployment by E/One after execution of this Agreement shall
be submitted to final and binding confidential arbitration.  Except as
specifically provided herein, the arbitration shall be governed by the rules of
the American Arbitration Association or such other rules as agreed to by the
parties with such arbitration to occur in Albany, New York.  Each party shall be
responsible for its or his own costs and attorneys' fees relating to mediation
and arbitration.  Both parties agree that the procedures outlined in this
paragraph are the exclusive methods of dispute resolution.

8.   ENTIRE AGREEMENT.

     This Agreement contains the entire agreement between you and E/One
concerning the subject matters discussed herein.  Any modification of this
Agreement shall be effective only if in writing and signed by each party or its
duly authorized representative.  This Agreement supersedes all prior employment
agreements between you and E/One or any corporation affiliated with or related
to E/One.  The terms of this Agreement are contractual and not mere recitals.
If for any reason any provision of this Agreement shall be held invalid in whole
or in part, such invalidity shall not affect the remainder of this Agreement.

     This Agreement shall be construed in accordance with the laws of the state
of New York (without regard to the conflicts of laws provisions thereof).

                             CHANGE OF CONTROL AGREEMENT


     This AGREEMENT is made as of January 5, 1998, by and between ENVIRONMENT
ONE CORPORATION, with offices located in Niskayuna, New York ("Corporation"),
and STEPHEN V. ARDIA, an individual employed by the Corporation ("Employee").


                                     WITNESSETH:

     WHEREAS, the Corporation's Board of Directors (the "Board") has authorized
the Corporation to enter into severance agreements with certain key employees of
the Corporation to encourage the continued dedication of the employee to the
Corporation and to promote the stability of Corporation management by providing
certain protections for the employee in the event a change of control of the
Corporation occurs; and

     WHEREAS, should the Corporation receive any proposal from a third person
concerning any possible business combination with, or acquisition of equity
securities of, the Corporation, the Board believes it imperative that the
Corporation be able to rely upon the Employee to continue in his position, and
that the Corporation be able to receive and rely upon his advice, if it requests
it, as to the best interests of the Corporation and its shareholders without
concern that the Employee might be distracted by the personal uncertainties and
risks created by such a proposal; and

     WHEREAS, should the Corporation receive any such proposals, in addition to
the Employee's regular duties, he may be called upon to assist in the assessment
of such proposals, to advise management and the Board as to whether such
proposals would be in the best interests of the Corporation and its
shareholders, and to take such other actions as the Board might determine to be
appropriate; and

     WHEREAS, the Board also desires to encourage the continued dedication of
the Employee to the Corporation and to promote the stability of the
Corporation's management by providing certain protections for the Employee in
the event that a change of control occurs with respect to the Corporation;

     NOW, THEREFORE, to assure the Corporation will have the continued
dedication of the Employee and the availability of his advice and counsel
notwithstanding the possibility, threat or occurrence of a bid to take over
control of the Corporation, and to induce the Employee to remain in the employ
of the Corporation, and for other good and valuable consideration, the
Corporation and the Employee agree as follows:

<PAGE>

     1.   SERVICES DURING CERTAIN EVENTS.  In the event a "person" or "group"
(as such quoted terms are defined in Section 4(a)(ii) below) begins a tender or
exchange offer, circulates a proxy to shareholders, or takes other steps seeking
to effect a Change of Control (as defined in Section 4(a) below), the Employee
agrees that he will not voluntarily leave the employ of the Corporation and will
render the services contemplated in the recitals to this Agreement consistent
with his then current employment terms until the such person or group has
abandoned or terminated efforts to effect a Change of Control or until three (3)
months after a Change of Control has occurred, provided no adverse changes occur
in the Employee's authority, duties, or compensation.

     2.   CHANGE OF CONTROL PAYMENT.

          (a)  In the event a Change of Control (defined in Section 4(a) below)
occurs during the Employee's employment with the Corporation, the Corporation
shall be obligated, subject to the limitation contained in Section 2(b) below,
to pay the Employee, as compensation for services rendered to the Corporation,
an amount equal to:  (i) the amount of the Employee's annual base salary in
effect on the date the Change of Control occurs, and (ii) an amount equal to the
sum of (A) the bonus payable to the Employee for the year during which the
Change of Control occurs, prorated through the date the Change of Control
occurs, plus (B) the average annual bonus paid to the Employee for the two
complete fiscal years that precede the fiscal year during which the Change of
Control occurs.  In addition, the Corporation shall waive for 12 months
following the Employee's termination of employment (whenever such termination
shall occur) any required premium payment due from the Employee to allow the
Employee to continue the Employee's coverage under the Corporation's group
health plan pursuant to Public Law 99-272, Title X (i.e., "COBRA").  The
Employee shall not be entitled to the foregoing change of control benefits if
the Employee is terminated for Cause (as defined in Section 4(b)) prior to the
Change of Control.  Amounts payable by the Corporation pursuant to this Section
2(a) shall be paid to the Employee in substantially equal installments (subject
to any applicable payroll or other taxes required to be withheld), over a one
year period, without interest, with the first such payment made not later than
30 days after the date the Change of Control occurs and with succeeding
installments paid in accordance with the Corporation's regular payroll cycles
for executive employees.  In the event the Employee dies prior to the payment of
all amounts due pursuant to this Section 2(a), remaining unpaid installments
shall be paid to his estate.  Notwithstanding the foregoing, at the sole
election of the Corporation, the entire amount payable to the Employee pursuant
to this Section 2(a) may be paid in a lump sum, not later than the 30th day
following the date the Change of Control occurs.

          (b)  Notwithstanding anything in this Agreement to the contrary, in
the event that the amount payable to the Employee pursuant to Section 2(a)
above, when added to all other amounts paid or to be paid to, and the value of
all property received or to be received by the Employee in anticipation of or
following a Change of Control, whether paid or received pursuant to this
Agreement or otherwise (such other amounts and property being referred to herein
as "Other Change of Control Payments"), would constitute an excess parachute
payment within the meaning of Section 280G of the Internal Revenue Code of 1986,
as 


                                         -2-
<PAGE>

amended (or any successor or renumbered section), then the amount payable
pursuant to Section 2(a) of this Agreement shall be reduced to the maximum
amount which, when added to such Other Change of Control Payments, does not
constitute an excess parachute payment.

     3.   OTHER EMPLOYMENT.  The Employee shall not be obligated to seek other
employment in mitigation of the amounts payable or arrangements made under any
provision of this Agreement, nor shall any payments under this Agreement be
reduced on account of any compensation, benefits or service credits for benefits
from any employment that the Employee may obtain following his termination of
employment with the Corporation.

     4.   DEFINITIONS.  For purposes of this Agreement, the following terms
shall have the following respective meanings:

          (a)  A "CHANGE OF CONTROL" shall be deemed to have taken place if
               either:

                    (i)    as the result of, or in connection with, any tender
               or exchange offer, consolidation, merger or other business
               combination, sale of assets or contested election or any
               combination of the foregoing transactions (a "transaction"), the
               persons who were directors of the Corporation before the
               Transaction shall cease for any reason to constitute a majority
               of the Board of Directors of the Corporation or any successor to
               the Corporation; or 

                    (ii)   any "person" (as that term is used Section 13(d) and
               14(d)(2) of the Securities and Exchange Act of 1934 (the
               "Exchange Act") as in effect on the date hereof), including a
               "group" as defined in Section 13(d)(3) of the Exchange Act,
               becomes the beneficial owner, directly or indirectly, of shares
               of the Corporation having more than 20% of the total number of
               votes that may be cast for the election of directors of the
               Corporation; or

                    (iii)  the Corporation is merged or consolidated with
               another corporation and as a result of the merger or
               consolidation less than 20% of the outstanding voting securities
               of the surviving or resulting corporation shall then be owned in
               the aggregate by the former stockholders of the Corporation,
               other than affiliates within the meaning of the Exchange Act or
               any party to the merger or consolidation; or

                    (iv)   a tender offer or exchange offer is made and
               consummated for the ownership of securities of the Corporation
               representing more than 20% of the combined voting power of the
               Corporation's then outstanding voting securities; or


                                         -3-
<PAGE>

                    (v)    the Corporation transfers substantially all of its
               assets to another corporation which is not a direct or indirect
               wholly-owned subsidiary of the Corporation.

          (b)  "CAUSE" shall mean (i) conduct involving fraud, misappropriation
or intentional material damage to the property or business of the Corporation,
or commission of a felony, (ii) failure or breach to perform Employee's
designated duties consistent with his position with the Corporation after
receiving written notice from the Corporation specifying the nature of the
alleged failure or breach and failing to correct the failure or breach within 15
days of such notice, or (iii) Employee's intentional violation of the
Corporation's written policies, Employee's fiduciary duties, or any law or
regulation which results in material damage or cost to the Corporation.

     5.   TRADE SECRETS.  It is recognized that the Corporation has acquired and
developed and will continue to acquire and develop techniques, plans, processes,
computer programs, and lists of customers and their particular requirements
which may pertain to Corporation related services and equipment, and related
trade secrets, know-how, research and development, which are proprietary and
confidential in nature and are and will continue to be of unique value to the
Corporation and its business (all hereinafter referred to as "Confidential
Information").  All Confidential Information known or in the possession of the
Employee shall be kept and maintained by him as confidential and proprietary to
the Corporation.  The Employee shall not disclose any Confidential Information
at any time directly or indirectly, in any manner to any person or firm, except
to other employees of the Corporation on a "need to know" basis.  Upon
termination of his employment for any reason, the Employee shall without demand
therefore deliver to the Corporation all Confidential Information in his
possession.  The obligations of this Section shall survive the termination of
this Agreement indefinitely.

     6.   SUCCESSORS.  This Agreement shall be binding upon and inure to the
benefit of the Employee and his estate, and the Corporation and any successors
of the Corporation, but neither this Agreement nor any rights arising hereunder
may be assigned or pledged by the Employee.

     7.   MISCELLANEOUS.  This Agreement represents the entire agreement between
the parties with respect to the subject matter of this Agreement and
specifically supersedes any and all oral or written agreements on its subject
matter previously agreed to by the parties.  

     8.   SEVERABILITY.  Any provision in this Agreement that is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
only to the extent of such prohibition or unenforceability without invalidating
or affecting the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not be invalidated or rendered
unenforceable such provision in any other jurisdiction.

     9.   CONTROLLING LAW.  This Agreement shall in all respects be governed by,
and construed in accordance with, the laws of the State of New York.

     10.  TERM OF AGREEMENT.

          (a)  INITIAL TERM AND RENEWAL.  The initial term of this Agreement
shall commence as of January 5, 1998, and shall continue through December 31,
1998, unless earlier terminated as provided herein.  Thereafter, this Agreement
shall be renewed for additional one year periods, unless either party gives
written notice of non-renewal of this Agreement to the other party at least
thirty (30) days prior to the expiration of the initial term or any renewal
term; provided, however, that in no case shall this Agreement terminate:
(i) within 12 months after the occurrence of a Change of Control, or (ii) during
any period of time when the Corporation has knowledge that any person or group
(such terms are defined in Section 4(a)(ii) above) has taken steps reasonably
calculated to effect a Change of Control until, in the opinion of the Board,
such person or group has abandoned or terminated his or its efforts to effect a
Change of Control.  Any determination by the Board that such person or group has
abandoned or terminated his or its efforts to effect a Change of Control shall
be conclusive and binding as the Employee.

          (b)  EMPLOYMENT "AT WILL".  Notwithstanding any provisions of this
Agreement, this Agreement shall not confer upon the Employee the right to be
retained in the service of the Corporation nor limit the right of the
Corporation to discharge or otherwise deal with the Employee.  Accordingly, the
Employee or the Corporation may terminate the Employee's employment with the
Corporation at any time with or without cause, subject to the provisions of this
Agreement.

     IN WITNESS WHEREOF, the parties have executed this Agreement as of the date
specified in the first paragraph of this Agreement.

     RE:  EMPLOYMENT AGREEMENT

Dear [FIRST NAME]:

     This Employment Agreement (this "Agreement") sets forth our agreement
concerning the terms of your employment by Environment One Corporation ("E/One"
or the "Company") following its acquisition by Precision Castparts Corp. ("PCC")
pursuant to an Agreement and Plan of Merger dated February 24, 1998 (the "Merger
Agreement") to become effective on the Tender Offer Acceptance Date as defined
in the Merger Agreement (the "Effective Date").

1.   EMPLOYMENT OFFER.

     1.1  EMPLOYMENT.

          (a)  You will assume the position of [INSERT TITLE] at E/One beginning
on the Effective Date and perform those duties as are generally associated with
such a position. You also agree to perform such acts and duties as the President
of the Company may reasonably direct, to comply with all reasonable applicable
policies and procedures of E/One and, as reasonably applicable, its parent and
affiliates, and to devote such time, energy and skill to your assignment as the
President and the Board of Directors of the Company considers reasonably
necessary for the performance of your duties, provided that you will not be
required to relocate from the Albany, New York area without your consent during
the term of this Agreement.

          (b)  Your employment with E/One will continue under this Agreement
from the Effective Date through the second anniversary of the Effective Date,
unless earlier terminated by you or E/One as expressly provided in paragraph
2.1, below. Your last day of employment with E/One is referred to herein as your
Separation Date.

     1.2  SALARY.

          During the term of this Agreement, you will be paid a base salary at
an annual rate of $_____________, payable in installments on regular Company
paydays.  Base salary increases during the first year of employment shall be
approved by the Company and the President of PCC Flow Technologies, Inc. in a
manner consistent with the Company's practice of considering salary increases in
April of each year.  Thereafter, base salary increases shall be set annually by
the Company, as approved by the Board of Directors.

     1.3  BENEFITS.

          In addition to your base compensation, you will be entitled to
participate through December 31, 1998 in the E/One bonus plan as in effect
immediately prior to the Effective Date.  For the three-month period January 1,
1999 through March 28, 1999 you will be entitled to participate in a bonus
program similar to the E/One bonus program in effect for calendar year 1998,
except that bonus targets will be determined by the Company's Board of Directors
in its sole discretion and will be keyed to 1999 objectives established by the
Company's Board of Directors. Thereafter, any bonus program provided will be
consistent with the bonus programs provided by PCC Flow Technologies to the
executives of its operating companies subject to approval by PCC.  You will also
continue to receive the same or comparable non-bonus employee benefits as
provided by E/One during your employment immediately prior to the Effective
Date, provided that (i) the E/One stock option plans will be eliminated, and
(ii) the E/One Deferred Compensation Plan will be amended to eliminate the E/One
stock investment provisions and to provide for alternate investment options.
Amounts received under the bonus plan in respect of calendar year 1998 will be
eligible for deferral under the E/One Deferred Compensation Plan, but no other
future deferrals will be permitted under that plan.  You will also be eligible
to participate in PCC's stock option and stock purchase programs in accordance
with the terms of those programs.

2.   TERMINATION OF AGREEMENT.

     2.1  TERMINATION.  The term of this Agreement shall be as stated in
subparagraph 1.1(b) (the "natural expiration date"), unless terminated earlier
as follows:


<PAGE>

[NAME]
February 27, 1998
Page 3


          (a)  This Agreement may be terminated by you for any reason upon 30
days' written notice to E/One.

          (b)  This Agreement may be terminated by E/One with or without cause
upon 30 days' written notice to you, subject only to the obligation of E/One,
(i) if you are teminated by E/One for reasons other than that specified in
paragraph 2.2 at any time before the first anniversary of the Effective Date, to
pay as a severance payment the remaining balance of your base salary for the
portion of the year from the Separation Date until the first anniversary date of
the Effective Date, plus 100 percent of any calendar year 1998 bonus to which
you would have been entitled had you remained employed by E/One through December
31, 1998, plus the Severance Payment (as defined below), or (ii) if you are
terminated for reasons other than those specified in paragraph 2.2 at any time
after the first anniversary of the Effective Date and prior to the second
anniversary of the Effective Date, to pay severance pay equal to ten month's pay
at the then current salary level (the "Severance Payment"). In addition, if you
are terminated by E/One for reasons other than specified in paragraph 2.2, E/One
shall waive for the remainder of the unexpired term of this Agreement any
required premium payment due from you to allow you to continue your coverage and
E/One's group health plan pursuant to Public Law 99-272, Title 10 (i.e,
"COBRA"), provided that this benefit shall terminate in any case upon the
earlier of 18 months after the Separation Date or upon your employment by a
successor employer.   Subject to 2.1(e) below, any severance payment payable
under this paragraph 2.1(b) shall be paid in a lump sum within ten (10) days
following the Separation Date, and shall be subject to applicable withholding,
except that any amounts relating to the 1998 bonus shall be paid at the same
time that 1998 bonuses are paid to continuing employees.

          (c)  This Agreement shall automatically terminate in the event of your
death or disability prior to the natural expiration date.  For purposes of this
Agreement, "disability" shall mean inability to perform all or substantially all
of your responsibilities for a period of more than six (6) months.

          (d)  Your employment shall not be deemed terminated under this
Agreement if you are assigned additional or different titles, and/or tasks and
responsibilities from those then-currently held or assigned with E/One, provided
that any such changes leave you with responsibilities consistent with your area
of professional expertise and your compensation is not decreased.

          (e)  Payment of the severance pay under paragraph 2.1(b) is subject to
your execution of a Release of Claims in a form provided by the Company
releasing any claims related to termination of your employment and rights to
payment under this Agreement.

     2.2  INELIGIBILITY FOR SEVERANCE PAY OR ADDITIONAL COMPENSATION.  With
respect to subparagraph 2.1, you will not be eligible for severance pay under
this Agreement and your compensation and benefits will end on your Separation
Date if:

          (a)  if you voluntarily resign or retire from your employment at any
time and for any reason;

          (b)  if your employment terminates due to the natural expiration of
this Agreement;

          (c)  if E/One terminates your employment at any time for cause (as
defined in paragraph 2.3, below) or your employment terminates due to death or
disability (as defined in paragraph 2.1(c));

          (d)  if you breach the terms of paragraph 3;

          (e)  if you are offered and accept reasonably comparable employment
with any business entity related to or affiliated with PCC; or

          (f)  you fail or refuse to sign the Release of Claims form described
in paragraph 2.1(e).

     2.3  DEFINITION OF CAUSE.  For purposes of this Agreement, "cause" for
termination shall be defined as termination of your employment with E/One for
(i) willful and continuous failure by you, in the judgment of the Company, to
substantially perform your reasonably assigned duties, responsibilities and
objectives with E/One, after a written demand for substantial performance is
made by the Company which identifies the manner in which you have not
substantially performed your duties or responsibilities or met your objectives,
as applicable and failure to correct such performance within 30 days following
the notice; (ii) commission by you of any act of fraud or dishonesty or any
felonious act; (iii) commission by you of any act of willful misconduct that, in
the judgment of the


<PAGE>

Company, materially and adversely affects the financial condition of the
Company; or (iv) breach of any material provision of this Agreement.

3.   CONFIDENTIALITY, NON-SOLICITATION AND NON-COMPETITION.

     3.1  PRESERVATION AND NON-USE OF CONFIDENTIAL INFORMATION.  You acknowledge
that you have a fiduciary duty as an officer and employee of the Company not to
discuss Confidential Information obtained during your employment with the
Company.  For purposes of this Agreement, "Confidential Information" means any
and all confidential or proprietary information concerning the Company or its
affiliates, joint venturers or other related entities (the "E/One Group"), the
disclosure of which could disadvantage the E/One Group.  Confidential
Information includes trade secrets as defined under the Uniform Trade Secrets
Act.

     You agree not to use Confidential Information, during the term of this
Agreement or after its termination, for any personal or business purpose, either
for your own benefit or that of any other person, corporation, government or
other entity.

     You also agree that you will not disclose or disseminate any Confidential
Information, directly or indirectly, at any time during the term of this
Agreement or after its termination, to any person, agency, or court unless
compelled to do so pursuant to legal process (E.G., a summons or subpoena) or
otherwise required by law and then only after providing the Company with prior
notice and a copy of the legal process.

     3.2  NON-SOLICITATION AND NON-COMPETITION.  You agree that you will not,
without the express written consent of the Board, for a period of one (1) year
following your Separation Date, directly or indirectly (by yourself or in
conjunction with any other person, company or organization), solicit or divert
any employee, customer or vendor of the Company or any of its affiliates, joint
venturers or other related entities.  You further agree that you will not,
without the express written consent of the Board, for a period of one (1) year
following your Separation Date, directly or indirectly, accept employment with
any person or entity involved in, or enter into any business relationship that
involves, the business of manufacturing or selling low pressure sewage systems
or grinder pumps (including, but not limited to, as a consultant, vendor,
partner, officer or director). The foregoing shall not preclude your employment
by a distributor of the Company's products in the case of your voluntary
termination of employment with the Company.  You


<PAGE>

Page 6


specifically acknowledge and agree that the terms of this provision are
reasonable in every respect and, in particular, because of the competitive and
specialized nature of the Company's business, that it is reasonable not to
include any geographic limitation in this provision.

4.   RETURN OF PROPERTY.

     On or before your Separation Date, except as agreed to by the Company, you
will return all property belonging to E/One, including, but not limited to, all
documents, business machines, computers, computer hardware and software
programs, computer data, telephones (cellular, mobile or otherwise), pagers,
keys, card keys, credit cards and other Company-owned property.

5.   ASSISTANCE IN DEFENSE OF LITIGATION OR CLAIMS.

     In the event E/One requests assistance during the one year period following
your Separation Date, you agree to provide reasonable assistance in defense of
ongoing or future litigation or claims about which you have knowledge without
additional compensation.  Thereafter, you agree to provide reasonable assistance
and will be paid for your assistance at an hourly rate equal to your hourly
equivalent rate of pay as of your Separation Date (for up to seven (7) hours in
one day) or per diem rate equal to eight (8) times your hourly equivalent rate
of pay as of your Separation Date (for more than seven (7) hours in one day).
You will be reimbursed for any reasonable expenses incidental to this assistance
approved in advance by the Company.  The Company will reasonably accommodate
your scheduling needs.

6.   RIGHT TO CONSULT WITH ATTORNEY.

     You have the right to consult with an attorney or financial advisor at your
own expense regarding this Agreement.

7.   DISPUTE RESOLUTION.

                     ACQUISITION AGREEMENT VALUED AT $72 MILLION

Niskayuna, New York - 25 February, 1998 - Environment One Corporation
(NASDAQ:EONE) and Precision Castparts Corp. (NYSE:PCP) have signed a definitive
agreement providing for the acquisition by Precision Castparts (PCC) of all
shares (approximately 4.72 million fully diluted) of Environment One at $15.25
in cash.  The total equity value of the transaction is $72 million.

Stephen V. Ardia, chairman and chief executive officer of Environment One said,
"E/One is excited to be able to combine its business with the PCC Flow
Technologies unit.  The acquisition recognizes the progress E/One has made in
the marketplace and represents a full and fair valuation for our shareholders,
while providing an enhanced growth platform for our customers, distributors and
associates.  In addition we are most pleased with the matching of value systems.
The success of the company has been a result of our team of associates who are
committed to growth supported by a system of shared rewards.  We firmly believe
that together we will continue to do great things."

William C. McCormick, chairman and chief executive officer of Precision
Castparts Corp. said "the combination of E/One's strengths with our existing
businesses will result in an even stronger competitor in markets such as
municipal sewer systems, residential building, land development, and single-
family dwellings."

"The adventuresome three-decade pilgrimage of E/One's independence has ended,
now it's time to get on with the next phase of the enterprise and build an even
more challenging and rewarding future for our customers, associates, and other
stakeholders.  We are absolutely convinced that E/One's outstanding products and
distribution will prosper with the encouragement and enthusiastic support from
PCC," according to Mr. Ardia.

The Nassau Group advised Environment One's Board of Directors in the transaction
and Miller, Johnson & Kuehn, acting as financial advisor, rendered its opinion
to the Board that the consideration to be paid and the tender offer is fair to
the stockholders to Environment One from a financial point of view.  As recently
as January 1, 1995 and 1997, E/One had a total equity value of approximately $9
million and $24 million, respectively.  On December 31, 1997 equity value had
risen to approximately $50 million on a fully diluted basis.  This transaction
at $72 million dollars represents a 45% premium over the December 31, 1997
valuation and a 17% premium over Tuesday, February 24, 1998 closing stock price.
