reasonable out-of-pocket expenses incurred in doing so.

                BOARD OF DIRECTORS AND COMMITTEES OF THE BOARD

The business of the Company is under general supervision of a Board of
Directors as provided by the laws of Delaware, the Company's state of
incorporation. The Board of Directors has established committees to assist it,
consisting of the Executive Committee, the Compensation Committee, the Audit
Committee and the Corporate Governance Committee.

Executive Committee. The Executive Committee consists of Messrs. McConomy
(Chairman), Cederna and Weil. The Executive Committee, during the intervals
between meetings of the Board, when prompt action is needed and it is
impossible or inconvenient to convene a full meeting of the Board, may
exercise limited powers granted by the Board of Directors in the management of
the business and affairs of the Company.

Compensation Committee. The Compensation Committee consists of Messrs.
Cruickshank (Chairman), Schofield and Surma. The Compensation Committee's
overall responsibility is to determine and implement the Company's general
policies with respect to the compensation of its executive officers. The
Compensation Committee determines the base salary payable to each executive
officer, as well as the bonus, if any, payable to each executive officer, and
to certain key employees, pursuant to the Company's Incentive Plan or
otherwise. The Committee also administers the Company's Stock Option Plan and
has the authority to grant options thereunder. Other matters related to the
compensation of executive officers and key employees, such as the terms of
employment contracts and certain employee benefits, are also reviewed by the
Compensation Committee.

Audit Committee. The Audit Committee consists of Messrs. Weil (Chairman),
Prater and Ms. Roberts. It is the responsibility of the Audit Committee to
review and approve the Company's consolidated financial statements

                                       4


each year prior to their announcement to the public and their distribution to
the stockholders in the Annual Report. Among other things, the Audit Committee
consults separately with the Company's chief financial officer and his staff,
and with the Company's independent external auditors, as to the proposed audit
plan, any difficulties encountered in carrying out the audit plan, significant
decisions made in preparing the financial statements, any disagreements
between management and the independent auditors as to the application of
accounting principles or other matters, and the form and content of the notes
to the financial statements and Management's Discussion and Analysis of the
financial statements. The Audit Committee also reviews the Company's quarterly
financial statements but does not customarily perform similar functions with
respect to other financial statements which cover less than a full fiscal
year. The Audit Committee reviews other financial reporting and accounting
matters when requested to do so by management or the independent auditors, and
satisfies itself that the Company's system of internal controls is functioning
adequately and reliably. The Audit Committee believes that the independent
auditors are ultimately accountable to the Board of Directors and the Audit
Committee. In this connection the Audit Committee discusses with the
independent auditors the quality, as well as the acceptability, of the
Company's accounting principles as applied in its financial reporting. The
Audit Committee periodically reviews all relationships between the Company and
the independent auditors which might impact the objectivity and independence
of the independent auditors. Each year the Audit Committee evaluates the
performance of the independent auditors and recommends to the Board of
Directors the retention or, if appropriate, replacement of the independent
auditors. The Audit Committee also investigates and reports to the Board as to
any alleged breach of law or of the Company's internal policies which is
brought to its attention and carries out other assignments given to it from
time to time by the Board.

Corporate Governance Committee. The Corporate Governance Committee consists of
Messrs. Yohe (Chairman), Cruickshank and McConomy. The Corporate Governance
Committee is responsible for the functioning of the Board and its committees,
with the goal of causing the Board and its committees to satisfactorily
address the major issues related to the performance and well-being of the
Company. Among the duties of the Corporate Governance Committee is to review
the size and composition of the Board of Directors and to make recommendations
with respect to nominations for election or appointment of Directors. The
Corporate Governance Committee will consider nominees recommended by
stockholders provided that stockholders submit the names of nominees and the
other information required by Section 1.08 of the By-Laws of the Company in
writing to the Secretary of the Company. Such information should be received
no later than January 21, 2003 with respect to nominations for election at the
2002 Annual Meeting of Stockholders.

During 2001, the Compensation Committee held four meetings, the Corporate
Governance Committee held three meetings, the Audit Committee held four
meetings, and the Executive Committee did not meet. The Board of Directors
held six meetings during 2001.

Compensation of Directors

Board and Committee Fees. Directors who are full-time employees of the Company
or a subsidiary receive no additional compensation for services as a member of
the Board or any committee of the Board. Directors who are not employees of
the Company receive an annual retainer of $18,000 for Board service. The
retainer fees are payable in cash or Common Stock of the Company as described
below. Non-employee Directors also receive a fee of $1,500 for each Board and
committee meeting attended, and the Chairmen of each committee receive an
additional annual retainer of $3,000. No committee meeting fees are paid for
committee meetings held by telephone or on the same day as a Board meeting.

1999 Phantom Stock Plan. The 1999 Phantom Stock Plan provides each non-
employee director with phantom stock with a value upon issuance of $7,000 each
year. No actual stock of the Company is issued under this plan. Instead, each
director is credited on the day following the Annual Meeting of Stockholders,
in an account maintained for the purpose, with the fair market value of shares
of the Company's Common Stock equal to

                                       5


$7,000. Directors are also credited with the fair market value of shares equal
to the amount of the cash dividends which would have been paid if the phantom
stock were actual Common Stock. As the actual fair market value of the
Company's Common Stock changes, the credited value of the director's phantom
stock will change accordingly. When the director leaves the Board for any
reason, including death or disability, the director will be entitled to be
paid, in cash, the entire amount then credited in the account.

1997 Directors' Fee Plan. The 1997 Directors' Fee Plan provides Directors with
payment alternatives for retainer (but not meeting) fees payable as a member
of the Board or as the Chairman of any committee. Pursuant to the Plan,
Directors are permitted to receive their retainer fees in a current payment of
cash or in a current payment of shares of Common Stock of the Company based
upon the fair market value of the Common Stock upon the date of payment of the
fee, or to defer payment of the retainer fees for subsequent payment of shares
of Common Stock pursuant to a stock deferral election. Payment of Common Stock
placed in a deferred stock account will be made in the calendar year following
the calendar year during which a Director ceases to be a Director of the
Company, including by reason of death or disability.

1993 Non-Employee Directors' Stock Option Plan. The 1993 Non-Employee
Directors' Stock Option Plan, as amended in 1997, provides for an annual grant
on the day following the Annual Meeting of Stockholders of option shares equal
to a number of shares which will result in a Black-Scholes calculated value of
$25,000 on the date of grant. The options vest and become exercisable six
months after the date of grant and, in general, expire ten years after the
date of grant. There are previously issued options outstanding under the pre-
1997 Plan, all of which have option prices in excess of the fair market value
of the Common Stock on December 31, 2001.

                             ELECTION OF DIRECTORS

The Board of Directors, acting pursuant to the bylaws of the Company, has
determined that the number of Directors constituting the full Board of
Directors shall be nine at the present time. The Board size will decrease to
eight after the Annual Meeting. The Board is to be divided into three classes
of nearly equal size. One such class is elected every year at the Annual
Meeting for a term of three years.

The Board of Directors has, upon recommendation of the Corporate Governance
Committee, nominated Seth E. Schofield and John P. Surma for reelection as
Directors in the Class of 2005, and each of them has agreed to serve if
elected. Mr. Nick H. Prater is retiring from the Board as of the Annual
Meeting. Messrs. Schofield and Surma will hold office until the 2005 Annual
Meeting of Stockholders, or until the Director's prior death, disability,
resignation or removal. Proxies are solicited in favor of these nominees and
will be voted for them unless otherwise specified.

If any nominee becomes unable or unwilling to serve as a Director, it is
intended that the proxies will be voted for the election of such other person,
if any, as shall be designated by the Board of Directors.

Information concerning the nominees for Director and the other Directors who
will continue in office after the meeting is set forth below, together with
information concerning the Company's executive officers who are not Directors.

                            EXECUTIVE COMPENSATION

In 1985 the Board of Directors created a Compensation Committee, consisting of
at least three Directors who are not employees of the Company. One of the
functions of the Compensation Committee is to review the compensation of the
Company's executive officers and methodology from which such compensation is
derived. The Compensation Committee then makes recommendations to the Board of
Directors on such matters, except for the granting of stock options, which is
done by the Committee alone.

The following is the report of the members of the 2001 Compensation Committee,
Messrs. Cruickshank (Chairman), Schofield and Surma, concerning 2001
compensation of the Company's executive officers.

Compensation Committee Report on Executive Compensation

            General policies with respect to executive compensation
            -------------------------------------------------------

The Compensation Committee's policies with respect to executive compensation
are intended to achieve three principal goals.

First, they are intended to create base compensation levels sufficient to
attract and retain talented and dedicated executive officers. To accomplish
this, the Committee periodically compares the Company's base salaries with
those currently paid for similar positions by other companies. The Committee
also reviews the total compensation package available to executive officers to
ensure it remains competitive.

Second, the compensation policies are intended to provide a direct link
between both individual performance and performance of the Company as a whole,
with the officer's compensation. This is done through bonuses available to
executive officers.

Third, the compensation policies are intended to provide executive officers
with the opportunity to acquire an equity stake in the Company through the
granting of stock options. These options are granted at full market prices and
with delayed vesting provisions.

The Committee's general philosophy is that salaries for the Company's
executive officers should be somewhat less than the median salaries paid by
other companies for comparable positions, so that the potential compensation
of an executive officer in a particular year will be more heavily weighted
toward incentive compensation such as bonus and stock options.

                             Compensation in 2001
                             --------------------

Salary. Base salaries are designed to be at levels at or slightly below those
of executive officers of comparable companies. The Committee considers a
number of factors in its discretion and does not determine base salaries
solely by any formula or objective basis. The Committee also uses outside
consultants from time to time in this area.

In 2001, the Committee reviewed the salaries of the executive officers and
recommended adjustments from 0% to 9%.

Bonus. In late 1999, the incentive compensation system was modified to provide
a more direct link between the employees bonus and performance. The new
compensation system is based on both economic profit and individual
performance. In this context, economic profit is defined as "Net Operating
Profit After Taxes" (NOPAT) compared to the "Cost of Capital Employed".
Economic profit is measured at various levels in the corporation and the
objective is to link changes in economic profit with executive bonuses. In
addition, individuals also have specific performance objectives that influence
their bonus. The interaction of economic

                                       9


profit and individual performance determines an employee's bonus. Based on the
performance of the Company and the individual being evaluated, the Committee
granted the bonuses set forth in the summary compensation table in 2001. In
2001, the incentive compensation system was expanded to include all salaried
employees.

Stock options. Under the terms of the Company's Stock Option Plan adopted in
1985, the Committee determines which employees will be granted stock options,
the number of options granted, the rate and period of vesting, and other
relevant terms.

In determining whether to grant options, the Committee takes into account the
number of outstanding options, the market price of the Company's Common Stock,
the performance of the Company and its prospects, potential dilution which
could result from exercise of options and the benefits of linking the
employees' incentive to the market price of the stock. These matters are at
the discretion of the Committee, and are not determined by any formula or
weighting of particular factors.

In determining whether to grant options to a particular individual, the
Committee considers the individual's level of responsibility, the relationship
between successful individual effort and Company results, incentive
compensation available from other companies, the number of unexercised options
held by the individual, and other relevant factors.

In 2001, the Committee granted 619,700 options to employees. Executive
officers (other than Mr. Cederna) received a total of 160,000 options which
currently remain outstanding.

The Stock Option Plan makes stock appreciation rights, payable in cash, and
restricted shares available for grant, but the Committee has not granted any.

                  Compensation of the chief executive in 2001
                  -------------------------------------------

In April 1999, the Company hired James A. Cederna as President and Chief
Executive Officer. Under the terms of his employment agreement, Mr. Cederna
receives a base pay of $500,000. Based upon results under the Company's
economic profit plan, Mr. Cederna was paid a $75,000 bonus for 2001. Also
under the terms of his employment agreement, Mr. Cederna received 100,000
stock options, one fourth of which vested immediately and the remainder of
which vest over a three-year period. These options reflect the Committee's
desire to link a major portion of Mr. Cederna's future compensation to
increases in the market price of the Company's Common Stock and thus directly
benefit stockholders.

                                  Tax policy
                                  ----------

If an executive officer's compensation from the Company were to exceed $1
million in any taxable year (which the Committee does not now expect), the
excess over $1 million, with certain exceptions, would not be deductible by
the Company, under Section 162(m) of the Internal Revenue Code of 1986, as
amended. The Committee is aware of this rule, and will take it into account if
the $1 million limit is ever applicable. One exception to the disallowance of
such deductions under Section 162(m) involves compensation paid pursuant to
stockholder-approved compensation plans that are performance-based. The
Company's Stock Option Plan contains provisions which are intended to cause
grants of stock options under such plan (after April 1999) to be eligible for
this performance-based exception (so that compensation upon exercise of such
options should be deductible under the Code). Payments of cash compensation to
executives (and certain other benefits which could be awarded under the plan,
such as restricted stock) are not at present eligible for this performance-
based exception.

Employment Agreements

All the executive officers of the Company have entered into employment
agreements with the Company. The agreements generally provide for continued
employment of the officers until terminated by the Company with or without
cause. Officers terminated without cause are entitled to severance
compensation of up to one year's base salary plus equivalent benefits until
the employee is employed by another employer for compensation at least equal
to 90% of his prior compensation at the Company. The agreements provide for a
base salary and for bonus compensation as determined by the Company. The
agreements also contain change in control provisions pursuant to which, if a
change in control (as defined in the agreements) occurs, the employee is
permitted to terminate employment on a date which is within the period
beginning on the first anniversary of such change in control and ending on the
second anniversary. If an employee terminates his or her employment as
provided above, or if the Company terminates the employee other than a
termination for cause within three years after the change in control, the
Company is required to pay severance compensation to the employee for up to 36
months (or, if earlier, until the employee is employed by another employer for
compensation at least equal to 90% of his prior compensation) equal to his or
her monthly compensation (including salary but not bonuses) for the calendar
year immediately prior to termination. In addition, for such period the
employee will receive equivalent benefits as were provided at the time of
termination and any then unvested stock benefits held by the employee will
vest. The agreements also contain confidentiality and non-compete provisions.

                                      12


Mr. Cederna has an employment agreement which provides that he shall be
employed through April 1, 2004. His employment will continue, unless otherwise
terminated in accordance with the agreement, for successive renewal periods of
one year each, commencing on January 1 in each renewal period. If Mr.
Cederna's employment is terminated due to board dissatisfaction or without due
cause, Mr. Cederna is entitled to severance compensation as described below
for a severance period of 24 calendar months, and Mr. Cederna would not be
entitled to acceleration of vesting on any stock benefits then held by him. If
Mr. Cederna's employment is terminated after a change in control, Mr. Cederna
is entitled to severance benefits as described below for a severance period of
36 calendar months, and all stock benefits not vested at the time of
termination would vest. If Mr. Cederna's employment is terminated by Mr.
Cederna following a change in control, then Mr. Cederna is entitled to
severance compensation for a severance period of six calendar months after
such termination, and Mr. Cederna's stock benefits would be accelerated. If
Mr. Cederna's employment is terminated for due cause by the Company, then Mr.
Cederna is not entitled to any severance pay or any acceleration of stock
benefits. If Mr. Cederna's employment is terminated by Mr. Cederna upon a
breach by the Company of the agreement, then Mr. Cederna is entitled to
severance compensation for a severance period of three calendar months, or
through the initial term of the contract, whichever is longer, and Mr.
Cederna's stock benefits would be accelerated. If Mr. Cederna's employment is
terminated by Mr. Cederna for any other reason, then Mr. Cederna is not
entitled to any severance pay or any acceleration of stock benefits.

Severance compensation means, in general, the amount of salary and cash bonus
received by Mr. Cederna for the calendar year immediately prior to the year in
which notice of termination is given. The severance period shall end on the
date, if ever, when Mr. Cederna is employed by another employer for total
compensation equal to at least 90% of his severance compensation. In addition,
during the severance period Mr. Cederna would receive equivalent benefits as
were provided to him at the time of termination. Mr. Cederna's agreement also
contains confidentiality and non-compete provisions.

Mr. Cederna's agreement provides that he shall be entitled to an annual grant
of stock options to purchase 100,000 shares of Common Stock at the fair market
value of such stock on the first business day of April of each year, subject
to customary vesting provisions. In addition, Mr. Cederna's agreement provides
that, in connection with his annual bonus under the Company's Incentive Plan,
the plan will provide that in the case of Mr. Cederna no such bonus is to
exceed 125% of his annual salary.

The Company historically has used the S&P Chemicals Specialty Composite Index
as a comparative benchmark. This group of companies can generally be described
as companies involved in the manufacture of specialty chemical products. The
Company believes that its core business consists of purifying air, water and
other products. As such, the Company has started using as a comparative peer
group benchmark, the companies included in the Robert W. Baird & Co.
Filtration/Separation Group. The companies included in this group include: BHA
Group Holdings Inc., Clarcor, Inc., Cuno, Inc., Donaldson Co. Inc., Esco

Flanders Corp., Ionics, Inc., Lydall, Inc., Millipore Corp., Osmonics Inc.,
and Pall Corp. The Company believes this peer group better mirrors the
Company's current and future core business activities of concentration,
separation and purification.

Pension Benefits

The Company's Retirement Plan for Salaried Employees is a non-contributory
defined benefit pension plan. In addition, the Company has a Supplemental
Retirement Plan, which is applicable to certain employees selected by the
Board of Directors, designed to supplement retirement benefits under the
Retirement Plan for Salaried Employees which have been limited by various
Internal Revenue Code provisions. At present no executive officers participate
in such Supplemental Retirement Plan. The following table shows the estimated
annual pension benefits which would be payable under the above-stated plans in
the form of a single life annuity, for various levels of average annual
compensation and years of service, based upon retirement at age 65 in the
calendar year 2001, before any reduction to take account of benefits payable
by the Company's former owner, Merck & Co., Inc. (by agreement with Merck,
benefits payable under Company plans are reduced by the benefit amounts
payable to the individual by Merck, which are computed utilizing a 2.5%
compensation increase assumption).

    during 2001 and under Section 401(a)(17) of the Code the amount of annual
    compensation of each employee taken into account under such plan for any
    year may not exceed $200,000 during 2002 and $170,000 during 2001. These
    limitations have not been reflected in the table.

Other than the reduction with respect to Merck benefits discussed above, the

Messrs. Cederna, Cann, Fischette, O'Brien and Stanik had two, two, 22, 28 and
10 years of service, respectively, under the plans. Pursuant to his employment
agreement, Mr. Cederna is entitled to retirement income under the plan, when
combined with amounts then payable to Mr. Cederna under the retirement plans
of former employers of Mr. Cederna, equal to the retirement income he would
have received under the plan (without the application of any maximum amount of
retirement income specified in the plan) if his years of credited service
under the plan had included the years of his full-time employment by such
other employers.

                             INDEPENDENT AUDITORS

Report of the Audit Committee

Under the charter of the Audit Committee adopted by the Board of Directors in
1999 and reviewed annually, the Committee's mission is to be the principal
means by which the Board of Directors oversees management's preparation and
public disclosure of financial information about the Company. The objective is
to make available to the public financial statements and other financial
information of high quality, accurate, complete, timely, fairly presented, and
complying with all applicable laws and accounting standards.

In overseeing the audit process for the year 2001, the Audit Committee
obtained from Deloitte & Touche LLP, the Company's independent auditors, their
letter required by Independence Standard No. 1, "Independence Discussions with
Audit Committees," describing all relationships between the auditors and the
Company that might, in their opinion, bear on their independence. In that
letter Deloitte & Touche LLP stated that in their judgment they are, in fact,
independent. The Committee discussed with the auditors the contents of that
letter and concurred in the judgment of independence.

The Committee reviewed with the auditors their audit plan, audit scope and
identification of audit risks. Subsequently, the Audit Committee reviewed and
discussed the audited financial statements of the Company as of and for the
year ended December 31, 2001, first with both management and the independent
auditors, and then with the auditors alone. This discussion covered the
quality, not just the acceptability, of the Company's financial reporting
practices and the completeness and clarity of the related financial
disclosures. The Committee also received and discussed, with and without
management present, all communications from Deloitte & Touche LLP required by
generally accepted auditing standards, including those described in Statement
on Auditing Standards No. 61, "Communications with Audit Committees."

The Audit Committee then recommended to the Board of Directors that the
audited financial statements be approved by the Board, be included in the
Company's Annual Report on Form 10-K for the year ended December 31, 2001, for
filing with the Securities and Exchange Commission, and be included in the
Company's annual report to stockholders for the year 2001.

In periodic meetings with the Company's financial management and the
independent auditors, the Audit Committee discussed and approved quarterly
interim financial information prior to its release to the public. The
Committee also performed the other functions required of it by its charter.

Management, not the Audit Committee, has the principal responsibility for
maintaining adequate internal controls and information reporting systems, and
for preparing financial statements and other reports to the public and to
regulatory bodies. Similarly, professionally trained personnel of the Company,
or of accounting firms and law firms retained for the purpose, are primarily
responsible for compliance with legal and accounting standards. The
independent auditors are responsible for auditing the annual financial
statements and reviewing the quarterly financial information.

 HARRY H. WEIL, CHAIRMAN
 NICK H. PRATER
 JULIE S. ROBERTS

On April 7, 2000, the Board of Directors of the Company, upon recommendation
of the Audit Committee, approved the dismissal of the Company's independent
accountants, PricewaterhouseCoopers LLP ("PWC") to be effective immediately.

                                      16


The audit reports of PWC on the Company's financial statements as of December
31, 1999 and 1998 and for the years then ended did not contain an adverse
opinion or a disclaimer of opinion and were not qualified or modified as to
uncertainty, audit scope or accounting principles. In connection with the
audits of the Company's financial statements as of December 31, 1999 and 1998
and for the years then ended and through the date of this report, the Company
believes there were no disagreements (as defined in Item 304 of Regulation S-
K). PWC believes that discussions surrounding two potential charges to the
Company's restructuring reserve, which were never recorded, constitute a
disagreement as defined in Item 304 of Regulation S-K. With the exception of
this difference of opinion, there were no issues with PWC on any matters of
accounting principles or practices, financial statement disclosure, or
auditing scope or procedure, which matters, if not resolved to the
satisfaction of PWC, would have caused PWC to make reference to the matter in
its reports on the financial statements for such years. The Company's Audit
Committee was informed by PWC about the discussions related to the
restructuring reserve. PWC stated that they agreed with the accounting for the
final restructure reserve. The Company has also authorized PWC to respond
fully to any and all inquiries of the successor accountant.

During the years ended December 31, 1999 and 1998 and through April 7, 2000,
there were no reportable events as defined in Item 304(a)(1)(v) of Regulation
S-K.

Current Independent Auditors

On April 7, 2000, the Audit Committee recommended and the Board of Directors
approved, the retention of Deloitte & Touche LLP as its new independent
accountants for the year ending December 31, 2000. During the years ended
December 31, 1999 and 1998 and through April 7, 2000, neither the Company nor
anyone else on its behalf consulted Deloitte & Touche LLP regarding any of the
matters or events set forth in Item 304(a)(2)(i) and (ii) of Regulation S-K.

Deloitte & Touche LLP audited the financial statements of the Company and its
subsidiaries in 2001. Representatives of Deloitte & Touche LLP are expected to
be present at the Annual Meeting. They will have the opportunity to make
statements if they desire to do so and will be available to respond to
appropriate questions.

Certain Fees

Audit Fees

The aggregate fees billed by Deloitte & Touche LLP, the member firms of
Deloitte Touche Tohmatsu and their respective affiliates (collectively
"Deloitte") for professional services rendered for the audit of the Company's
annual financial statements for the fiscal year ended December 31, 2001 and
for the reviews of the financial statements included in the Company's
Quarterly Reports on Form 10-Q for 2001 were $263,000.

Financial Information Systems Design and Implementation Fees

The aggregate fees billed by Deloitte for professional services rendered for
information technology services relating to financial information systems
design and implementation for the fiscal year ended December 31, 2000 were
$235,000.

All Other Fees

All other fees billed by Deloitte for the fiscal year ended December 31, 2001
were $637,000, including audit related services of $126,000 and other non-
audit services of $511,000. Audit related services generally include fees for
statutory audits, employee benefit plan audits and accounting consultations.
Other non-audit services generally include tax advice and tax return
assistance.

The Audit Committee believes that the provision of the above services by
Deloitte is compatible with maintaining Deloitte's independence.
