                OUTSTANDING VOTING SECURITIES AND VOTING RIGHTS

     The Board of Directors has established April 18, 2003 as the record date
for stockholders who are entitled to notice of, and to vote at, the annual
meeting and any adjournments or postponements of the annual meeting. On April
18, 2003, there were 15,803,797 shares of our common stock, par value $.01 per
share, and


15,000 shares of Series B Convertible Preferred Stock, par value $.01 per share,
issued and outstanding, which constituted the only outstanding voting securities
of NATCO. Each share of common stock is entitled to one vote. Each share of
Series B Convertible Preferred Stock is entitled to a number of votes equal to
the number of shares of common stock into which the Series B Convertible
Preferred Stock would convert if converted on the record date. If converted on
the record date, the Series B Convertible Preferred Stock would convert to an
aggregate of 1,921,845 shares of common stock, which equates to 128.123 votes
per preferred share. The holders of shares of Series B Convertible Preferred
Stock and holders of common stock shall vote together as one class on all
matters being submitted to a vote of NATCO's stockholders at the annual meeting.

     In addition, pursuant to the restated certificate of incorporation of
NATCO, as amended, so long as more than 50% of the Series B Convertible
Preferred Stock remains outstanding, the holders of the Series B Convertible
Preferred Stock have the right, voting separately as a class with one vote per
share, to elect or appoint one director at any annual or special meeting of
stockholders or pursuant to written consent. On March 25, 2003, the holders of
the Series B Convertible Preferred Stock acting by written consent elected Mr.
Thomas R. Bates, Jr. to serve as a director of the company pursuant to this
right. Accordingly, the holders of the Series B Convertible Preferred Shares
will not elect a director at the annual meeting. Mr. Bates will continue to
serve as a director at the pleasure of the holders of Series B Convertible
Preferred Stock for so long as this right continues. Following certain defaults
related to the payment of dividends on or the redemption price for the Series B
Convertible Preferred Stock, the holders of the Series B Convertible Preferred
Stock will be entitled to elect a second director, also voting separately as a
class with one vote per share.

     The presence, in person or by proxy, of the holders of a majority of all
the outstanding shares of stock entitled to vote at the meeting is necessary to
constitute a quorum at the annual meeting or any adjournment or postponement of
the annual meeting. Abstentions and broker non-votes will be counted in
determining whether or not there is a quorum at the annual meeting.

REQUIRED VOTES

     A plurality of the voting power of the shares present in person or
represented by proxy and entitled to vote at the annual meeting is required for
the election of directors. Accordingly, the three nominees for election as
directors at the annual meeting who receive the greatest number of votes cast
for election by the holders of record on April 18, 2003 shall be duly elected
directors upon completion of the vote tabulation at the annual meeting. The
affirmative vote of a majority of the voting power of the shares present in
person or represented by proxy and entitled to vote at the annual meeting is
required for the ratification of the selection of our independent auditors. An
automated system that our transfer agent administers will tabulate the votes.
Brokers who hold shares in street name for customers are required to vote shares
in accordance with instructions received from the beneficial owners. Brokers are
permitted to vote on discretionary items if they have not received instructions
from the beneficial owners, but they are not permitted to vote (a "broker non-
vote") on non-discretionary items absent instructions from the beneficial owner.
Both abstentions and broker non-votes will not have any effect on the outcome of
voting on director elections. For purposes of voting on the ratification of the
selection of auditors, abstentions will be included in the number of shares
voting and will have the effect of a vote against the proposal, and broker
non-votes will not be included in the number of shares voting and therefore will
have no effect on the outcome of the voting.

     A proxy in the accompanying form that is properly signed and returned will
be voted at the annual meeting in accordance with the instructions on the proxy.
Any properly executed proxy on which no contrary instructions have been
indicated about a proposal will be voted as follows with respect to the
applicable proposal: "FOR" the election of the three persons named in this proxy
statement as the Board of Directors' nominees for election to the Board of
Directors; "FOR" the ratification of the selection of KPMG LLP as our auditors;
and in accordance with the discretion of the holders of the proxy with respect
to any other business that properly comes before the stockholders at the annual
meeting. The Board of Directors knows of no matters, other than those previously
stated, to be presented for consideration at the annual meeting. The persons
named in the accompanying proxy may also, in their discretion, vote the proxy to
adjourn the annual meeting from time to time.
                                        2


STOCKHOLDER LIST

     A copy of the list of stockholders entitled to vote at the annual meeting
will be available for inspection by qualified stockholders for proper purposes
at our principal executive offices (2950 N. Loop West, Suite 700, Houston, Texas
77092) during normal business hours beginning on May 12, 2003 and at the annual
meeting.

                       PROPOSAL 1: ELECTION OF DIRECTORS

     Our amended and restated bylaws, as amended, provide that the Board of
Directors will be composed of eight members. The board has seven members serving
in three classes who are elected by holders of our voting stock, with two
members in Class I, three members in Class II and two members in Class III.
Directors in each class are elected for terms of three years, so that the term
of one class of directors expires at each annual meeting of stockholders. In
addition, the holders of the Series B Convertible Preferred Stock, voting as a
separate class, are entitled to elect one director at an annual or special
meeting of stockholders or by written consent. On March 25, 2003, the holders of
the Series B Convertible Preferred Stock, acting by written consent, elected Mr.
Thomas R. Bates, Jr. to serve as a director pursuant to their right.
Accordingly, the holders of the Series B Convertible Preferred Stock will not
separately elect a director at the annual meeting. Mr. Bates shall continue in
office until a successor has been elected by the holders of the Series B
Convertible Preferred Stock or until less than 50% of such series remains
outstanding.

NOMINEES

     Three directors are to be elected at the annual meeting. The Board of
Directors has nominated Mr. Keith K. Allan, Mr. Howard I. Bull and Mr. George K.
Hickox, Jr., to fill the three expiring Class II positions on the Board of
Directors, to hold office for three-year terms expiring at the annual meeting of
stockholders in 2006, until their respective successors have been duly elected
and qualified, or until their earlier resignation or removal. The enclosed proxy
(unless otherwise directed, revoked or suspended) will be voted "FOR" the
election of the three nominees for Class II director.

     Although we know of no reason why any of the nominees might be unable or
refuse to accept nomination or election, if any nominee should be unable to
serve as a director, the shares represented by proxies will be voted for the
election of a substitute nominated by the Board of Directors.

     THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE ELECTION OF THE DIRECTOR
NOMINEES.

     Set forth below are the names of, and certain information with respect to,
our executive officers and directors, including the three nominees for election
to the Class II positions on the Board of Directors.

COMMITTEES AND BOARD MEETINGS

     The Board of Directors currently has three committees: the Executive
Committee, the Audit Committee and the Governance, Nominating and Compensation
("GN&C") Committee.

     The Executive Committee consists of Mr. Gregory (Chairman), Mr. McCarthy
and Mr. Winokur. The committee was formed to exercise the powers of the board
during intervals between board meetings, to the extent permitted by law. The
Executive Committee did not meet in 2002.

     Our Audit Committee consists of Mr. Allan, Mr. Clarke and Mr. Hickox, each
of whom is a non-employee director. The Audit Committee, which is chaired by Mr.
Allan, meets separately with representatives of our independent auditors and
with representatives of senior management in performing its functions. The Audit
Committee reviews the general scope of audit coverages, the fees charged by the
independent auditors, matters relating to internal control systems and other
matters related to accounting and reporting functions.

     The GN&C Committee members are Mr. Bull, Mr. Clarke (Chairman) and Mr.
Winokur, each a non-employee director. The GN&C Committee's role is to assist
the Board of Directors in fulfilling its oversight responsibilities with respect
to governance, nomination of directors and executive compensation. In fulfilling
its nominating role, the committee assists the board in identifying individuals
qualified to become board members and in determining the composition of the
board of directors and its committees. On matters related to evaluation and
re-nomination of directors who are also members of the GN&C Committee, such
members abstain from the committee's deliberations and recommendations. In
fulfilling its compensation role, the committee assists the Board in assuring
that our senior executives are compensated effectively, in a manner consistent
with the stated compensation strategy of the company, internal equity
considerations, competitive practice and the requirements of applicable law,
regulations and rules of applicable regulatory bodies.

     In 2001 and prior years, performance evaluation of incumbent Directors and
recommendations for the Board nominations were the responsibility of the
Executive and Nominating Committee, whose members were Mr. Gregory, Mr. McCarthy
and Mr. Winokur. In February 2002, the Board of Directors transferred
responsibility for performance evaluations of incumbent Directors and
recommendations for Board nominees to the Compensation Committee, renamed it the
Compensation and Nominating Committee and appointed Mr. Clarke as a member of
the committee, joining Mr. Winokur and Mr. Bull. Mr. Winokur served as the
Chairman of that committee until December 2002, when the Board of Directors
renamed it the Governance, Nominating and Compensation Committee, and elected
Mr. Clarke as its Chairman. At this time, the GN&C Committee was assigned
overall responsibility for corporate governance policies and procedures and
monitoring compliance with the Sarbanes-Oxley Act of 2002 in regards to those
policies and procedures. With respect to governance matters, the GN&C
Committee's role is evolving, and will continue to do so as the laws, rules and
regulations related to corporate governance standards change.

     During 2002, the entire Board of Directors held six meetings, the Audit
Committee held nine meetings and the GN&C Committee held four meetings. Each of
the directors attended at least 75% of the board meetings and the committees of
the Board on which they served.

AUDIT COMMITTEE REPORT

     The Audit Committee operates under a charter that was adopted by the Board
of Directors on May 2, 2000 and was included in our 2000 proxy statement. During
its nine meetings in 2002, the Audit Committee met nine times with the company's
financial management and eight times with our independent certified

                                        7


public accountants, KPMG LLP, as part of its role in providing oversight to the
financial reporting process and internal control structure. KPMG LLP met with
the Audit Committee, without NATCO management representatives present, to
discuss the results of their examinations and quality of reporting.

     The Audit Committee reviewed and discussed with management our audited
financial statements for the year ended December 31, 2002. In addition, the
Audit Committee discussed with KPMG LLP matters required by Statement on
Auditing Standards No. 61.

     The Audit Committee also received and reviewed the written disclosures and
the letter from KPMG LLP required by Independence Standards Board Standard No. 1
and discussed with KPMG LLP their independence. The Audit Committee also
reviewed and discussed with our management and with KPMG LLP such other matters
and received such assurances from these parties that they deemed appropriate.

     Based on the foregoing review and discussions, the Audit Committee
recommended to our Board of Directors the inclusion of our audited financial
statements in the Annual Report on Form 10-K for the year ended December 31,
2002 filed with the Securities and Exchange Commission.

     The Audit Committee also considered whether the provision of the non-audit
services listed below is compatible with maintaining the independence of KPMG
LLP. The Audit Committee determined that such services were compatible with KPMG
LLP's independence.

     Audit Fees.  The audit fees paid by the company to KPMG LLP for the years
ended December 31, 2002 and 2001 totaled $433,945 and $396,206, respectively.

     Financial Information Systems Design and Implementation Fees.  KPMG LLP did
not provide such services to us for the years ended December 31, 2002 and 2001.

     All Other Fees.  All other fees paid to KPMG LLP for the years ended
December 31, 2002 and 2001 for services other than those disclosed above totaled
$56,273 and $365,924, respectively, including fees for non-audit services of
$30,523 and $300,674, respectively, and audit-related services of $25,750 and
$65,250, respectively. Non-audit services consisted of tax compliance and
consulting services, as well as certain due diligence in 2001 pertaining to an
acquisition. Audit-related services consisted of the audit of the financial
statements of an employee benefit plan and review of registration statements.

     The Audit Committee:

        Keith K. Allan (Chairman)
        John U. Clarke
        George K. Hickox, Jr.

GOVERNANCE, NOMINATING AND COMPENSATION COMMITTEE REPORT

     The GN&C Committee of the Board of Directors is responsible for developing
executive compensation policies that support NATCO's strategic business
objectives and values. The GN&C Committee has oversight responsibility in
establishing compensation levels for executive officers, setting guidelines for
company-wide compensation and employee benefit policies, and administering our
bonus plans and stock option plans. Our objectives in compensation for executive
officers and key employees are to attract and retain talented and experienced
people who will contribute to the long-term success of NATCO, to inspire
executive officers to work as a team to pursue our goals, and to align executive
officers' interest to those of NATCO, by providing for bonuses tied to company
performance, and to stockholders, by providing stock options as a portion of
compensation. The GN&C Committee monitors general industry conditions, changes
in regulations and tax laws, and other developments that may, from time to time,
require modification of the executive compensation program to ensure the program
is properly structured to achieve its objectives.

     In making compensation determinations, the GN&C Committee evaluates a
number of factors at the end of each year, including NATCO's performance
relative to our annual objectives, our performance relative to changes in the
industry and each executive officer's contribution to our performance during the
year. The GN&C Committee does not apply any particular formula or assign any
particular weight to any factors it

                                        8


considers in determining an executive's compensation. Instead, the committee
considers all of these factors together and makes a subjective determination
with respect to executive compensation. The annual base salary, bonus and stock
option awards paid or awarded to our chief executive officer and our other four
most highly compensated executive officers (the "Named Executive Officers") are
set forth in summary form in the Summary Compensation Table included in the
proxy statement of which this report forms a part.

     Salaries.  Executive officer salaries are based on a subjective evaluation
considering peer company data, the executive's responsibilities, performance and
length of time in the position, internal equities among positions and general
economic conditions. Overall compensation is intended to be at or modestly above
the median level of compensation for peer companies with which we compete for
employees. To determine salary levels paid within the industry, the GN&C
Committee reviews various industry surveys and proxy information of our
competitors and consults with independent compensation consulting firms from
time to time. The GN&C Committee reviews executive salaries at least annually,
and makes appropriate adjustments.

     Benefits.  Our benefit plans are intended to be at or modestly above the
median level of benefits for peer companies with which we compete for employees.
NATCO maintains a defined contribution pension plan (the 401(k) Savings Plan)
covering substantially all non-union hourly and salaried employees who have
completed three months of service. Employee contributions of up to 3% of each
covered employee's compensation are matched 100% by the company, with an
additional 2% of covered employee's compensation matched at 50%. In addition, we
may make discretionary contributions from time to time as profit sharing
contributions. The GN&C Committee reviews and approves all discretionary
matches. No discretionary match was provided for the year ended December 31,
2002.

     Bonus Awards.  Bonus awards are linked to the achievement of company-wide
and individual performance goals and are designed to put a significant portion
of total compensation at risk. Under the bonus plan, a bonus target is
established for each executive officer and key employee based on a subjective
evaluation considering peer company data and the executive officer or key
employee's level of responsibility and ability to impact our success. In 2002,
the individual bonus targets for executive officers ranged from 25% to 75% of
salary. After a year-end review, the GN&C Committee determines the amount of the
annual incentive payment, if any, that will be awarded to an executive officer
based on the GN&C Committee's subjective evaluation of the extent to which
company-wide and individual performance goals are achieved and general economic
and industry conditions.

     Stock Options.  We make stock option awards under the Stock Incentive Plan
to align the interests of executive officers and key employees with those of
stockholders. Options vest over multiple years at the fair market value of the
common stock on the date of grant. Therefore, these options will have no value
unless the company's stock appreciates in value. The GN&C Committee makes awards
based on a subjective evaluation considering peer company data and the executive
officer's or key employee's ability to impact our success. Consideration is also
given to amounts, timing and vesting status of previous awards to each executive
officer or key employee, total options outstanding and available under the plan,
and the level and volatility of our share price and the amount of appreciation
realized by the stockholders over comparable periods. Other than as part of the
initial compensation package for new key employees, the GN&C Committee did not
make any stock option awards with respect to 2002.

     Compensation of the Chief Executive Officer.  The Chief Executive Officer's
compensation primarily consists of base salary, annual incentive and long-term
incentives. The GN&C Committee establishes the Chief Executive Officer's pay
levels and incentives in the same manner as for other executive officers
described above. NATCO entered into a new, three-year employment agreement with
Mr. Gregory in December 2002, replacing his prior employment agreement with the
company. Pursuant to the prior agreement, Mr. Gregory's annual base salary for
the year ended December 31, 2002 was $400,000. Mr. Gregory's target bonus was
75% in 2002, of which the GN&C Committee awarded him $225,000. No stock options
were granted to Mr. Gregory in 2002. Options granted to Mr. Gregory in 2001 and
2000 represented 81,750 shares and 50,000 shares of common stock, respectively.

     Severance; Change of Control Agreements.  At the end of 2002, the GN&C
Committee undertook a review of our various severance policies and employment
arrangements with our executive officers, with the
                                        9


assistance of an independent compensation consulting firm. Based on this
analysis, the GN&C Committee authorized NATCO to enter into employment
agreements with the Chief Executive Officer and President containing the
recommended severance provisions, and authorized NATCO to enter into change in
control agreements with its other executive officers.

     Other Matters.  In 2001 and prior years, performance evaluations of
incumbent directors and recommendations for Board nominations were the
responsibility of the Executive and Nominating Committee, consisting of Mr.
Gregory, Mr. McCarthy and Mr. Winokur. In February 2002, the Board appointed Mr.
Clarke to the Compensation Committee, renamed the committee the Compensation and
Nominating Committee, and transferred to it responsibility for performance
evaluations of incumbent Directors and recommendations for Board nominees. In
December 2002, this committee was renamed the Governance, Nominating and
Compensation Committee, incorporating overall responsibility for corporate
governance policies and procedures and compliance with the provisions of the
Sarbanes-Oxley Act of 2002, in regards to those policies and procedures.

     The Governance, Nominating and Compensation Committee:

        John U. Clarke (Chairman)
        Howard I. Bull
        Herbert S. Winokur, Jr.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     During 2002, the Governance, Nominating and Compensation Committee
consisted of Mr. Bull, Mr. Clarke and Mr. Winokur, each a non-management
director. There were no GN&C Committee interlock relationships or insider
participation in compensation arrangements for the year ended December 31, 2002.

     See "Certain Relationships and Related Transactions" for information
regarding certain transactions between the company and Mr. Winokur.

                      DIRECTOR AND EXECUTIVE COMPENSATION

DIRECTOR COMPENSATION

     Directors who are our employees do not receive a retainer or fees for
service on the Board or any of its committees. We pay non-employee directors for
their services. Directors who are non-employees receive a quarterly fee of
$9,000 and a fee of $500 for attendance at each meeting of the Board. In
addition, pursuant to the 1998 Director Stock Option Plan, each non-employee
Director who is re-elected as a Director after completing at least one year of
service as a Director will receive, on the date of re-election, a stock option
to purchase 2,667 shares of common stock at the market price on the date of
grant. Some non-employee directors also have been awarded initial stock options
to purchase 6,667 shares of common stock at a price of $8.81 per share.
Directors are reimbursed for reasonable out-of-pocket expenses related to the
performance of their duties as directors. During 2002, Mr. Clarke undertook an
extensive review of the corporate governance of NATCO and provided the Board of
Directors a report on governance and the implications to NATCO of the
implementation of the Sarbanes-Oxley Act of 2002. After reviewing the matter
with outside counsel, the Board of Directors established the chairperson's fee
for the newly formed GN&C Committee at $18,000 through the 2003 annual meeting
of stockholders in recognition of the substantial time requirements necessary
for us to conform our corporate governance practice to newly-established
requirements.

                           EQUITY COMPENSATION PLANS

     Equity compensation plan information has been included under Item 12 in our
Annual Report on Form 10-K as of December 31, 2002, filed with the Securities
and Exchange Commission on March 21, 2003, and is incorporated in this proxy
statement by reference.

                     CERTAIN RELATIONSHIPS AND TRANSACTIONS

     Under the terms of an employment agreement in effect prior to 1999, we
loaned our Chief Executive Officer $1.2 million in July 1999 to purchase 136,832
shares of common stock. During February 2000, after we completed the initial
public offering of our Class A common stock, also pursuant to the terms of that
employment agreement, we paid this executive officer a bonus equal to the
principal and interest accrued under this note arrangement and recorded
compensation expense of $1.3 million. The officer used the proceeds of this
settlement, net of tax, to repay the company approximately $665,000. In
addition, on October 27, 2000, our Board of Directors agreed to provide a full
recourse loan to this executive officer to facilitate the exercise of certain
outstanding stock options. The amount of the loan was equal to the cost to
exercise the options plus any personal tax burdens that resulted from the
exercise. The maturity of these loans was July 31, 2003, and interest accrued at
rates ranging from 6% to 7.8% per annum. As of June 30, 2002, the outstanding
principal and interest on these notes receivable totaled $3.4 million. Effective
July 1, 2002, the notes were reviewed by our board and amended to extend the
maturity dates to July 31, 2004, and to require interest to be calculated at an
annual rate based on the London Inter-Bank Offered Rate ("LIBOR") plus 300 basis
points, adjusted quarterly, applied to the notes balances as of June 30, 2002,
including previously accrued interest. As of December 31, 2002, the outstanding
principal and interest due from this officer under these notes was $3.5 million.
These loans, which were made on a full recourse basis in prior periods to
facilitate direct ownership in our common stock, are currently subject to and in
compliance with provisions of the Sarbanes-Oxley Act of 2002.

     As previously agreed in 2001, we loaned our President $216,000 on April 15,
2002, under a full-recourse note arrangement which accrues interest at 6% per
annum and matured on July 31, 2003. The funds were used to pay the exercise cost
and personal tax burdens associated with the stock options exercised during
2001. Effective July 1, 2002, the note was amended to extend the maturity date
to July 31, 2004, and to require

                                        14


interest to be calculated at an annual rate based on LIBOR plus 300 basis
points, adjusted quarterly, applied to the note balance as of June 30, 2002,
including previously accrued interest. As of December 31, 2002, the outstanding
principal and interest on the note was approximately $223,000. This loan, which
was made on a full recourse basis to facilitate direct ownership in our common
stock, is currently subject to and in compliance with provisions of the
Sarbanes-Oxley Act of 2002.

     We pay Capricorn Management G.P., an affiliate company of Capricorn
Holdings, Inc., for administrative services, which include office space and
parking in Connecticut for our Chief Executive Officer, reception, telephone,
computer services and other normal office support relating to that space. Mr.
Herbert S. Winokur, Jr., one of our directors, is the Chairman and Chief
Executive Officer of Capricorn Holdings, Inc., and the Managing Partner of
Capricorn Holdings LLC, which is the general partner of Capricorn Investors II,
L.P., a private investment partnership, and directly or indirectly controls
approximately 31% of our outstanding common stock. In addition, our Chief
Executive Officer, Mr. Gregory, is a non-salaried member of Capricorn Holdings
LLC. Capricorn Investors II, LP controls approximately 20% of our common stock.
Fees paid to Capricorn Management for these administrative services totaled
$115,000, $85,000 and $75,000 for the years ended December 31, 2002, 2001 and
2000, respectively, with the increases in 2002 and 2001 primarily attributable
to an upward adjustment in Capricorn Management's underlying lease for office
space. The Audit Committee of our Board of Directors has responsibility for
reviewing and approving this arrangement.

     We recorded revenues of $65,705 for the year ended December 31, 2002,
related to equipment sold to the Wiser Oil Company. One of our Directors, Mr.
George K. Hickox, Jr., is the Chief Executive Officer of the Wiser Oil Company.
These sales constituted less than one percent of NATCO's consolidated gross
revenues. NATCO purchased no equipment from the Wiser Oil Company during 2002.

EMPLOYMENT, TERMINATION AND CHANGE OF CONTROL ARRANGEMENTS

     Mr. Gregory serves as our Chairman and Chief Executive Officer under an
employment agreement entered into in December 2002, which replaced his prior
employment agreement. The current agreement is for a term of three years unless
sooner terminated by Mr. Gregory or by us in accordance with its terms. The
agreement automatically extends for additional one-year periods unless we notify
Mr. Gregory 90 days prior to the termination date of the agreement that we do
not wish to renew the agreement. Under his agreement, Mr. Gregory is entitled to
receive an annual salary (currently $436,000), an annual bonus with a target
award of 75% of Mr. Gregory's base salary based on our financial performance and
certain other criteria as are determined annually by our Board of Directors, and
such additional bonus payments as the Board may determine in its sole
discretion. He is also entitled to participate in our fringe benefit and
insurance plans and to reimbursement of certain costs and expenses.

     If, prior to a change in control, we terminate Mr. Gregory's employment for
any reason other than cause, or Mr. Gregory terminates his employment for good
reason, Mr. Gregory will be entitled to severance pay in accordance with any
severance plan or policy that we may then have in effect and any bonus
compensation earned to that point under the bonus plan. If, during the 36-month
period following a change in control, Mr. Gregory terminates his employment
agreement for good reason or we terminate Mr. Gregory, other than for cause, Mr.
Gregory will be entitled to salary and accrued vacation through the date of
termination, annual bonus earned through the date of termination, three times
his base salary and target bonus at the time of notice of termination or of a
change in control, whichever is greater; continuation of health, dental and life
insurance benefit for a period of three years following the date of termination;
and all deferred bonus compensation under the bonus plan.

     Mr. McCarthy serves as our President under an employment agreement entered
into in December 2002. The terms of Mr. McCarthy's employment agreement are
substantially similar to those of Mr. Gregory under his employment agreement,
except that, under Mr. McCarthy's agreement, he is entitled to receive an annual
salary (currently $300,000), an annual bonus with a target award of sixty
percent of Mr. McCarthy's base salary, based on our financial performance and
certain other criteria which are determined annually by our Board of Directors,
and such additional bonus payments as the Board may determine in its sole
discretion. If,

                                        15


during the 36-month period following a change in control, Mr. McCarthy
terminates his employment agreement for a good reason or we terminate Mr.
McCarthy other than for cause, Mr. McCarthy will be entitled to the same
payment, benefits and treatment of his stock options as described above for Mr.
Gregory, except that the payment for his base salary shall be two times his base
salary at the time of notice of termination or change in control, whichever is
greater.

     In December 2002, we entered into Senior Management Change in Control
Agreements with our executive officers, including the other three named
executive officers, one of whom has since resigned from the company. These
agreements are for an initial term of three years, but renew for successive
one-year periods unless terminated earlier as provided in the agreement. If,
during the 24-month period following a change in control, the executives
employment is terminated by us other than for cause, or by the executive for
good reason, we are obligated to pay the executive's salary and accrued vacation
through the date of termination, annual bonus earned through the date of
termination, an amount equal to the product of two times the executive's base
salary at the time of termination or of notice of a change in control, whichever
is greater, continuation of health, dental and life insurance benefits for a
period of two years following the date of termination. These payments are in
lieu of any other severance to which the executive may be entitled under other
severance arrangements of the company, and are in addition to any stock options
of the executive.

     In addition, all unvested stock options held by any executive subject to an
employment or change in control agreement described above shall immediately vest
on the date of a change in control and the period for exercising certain of such
options may be extended. Also, for purposes of the above-referenced employment
and change in control agreements, the extent that any benefit, payment or
distribution by the company under the agreement would be subject to the excise
tax imposed by Section 4999 of the U.S. internal revenue code, then such amount
will be reduced to the extent necessary to avoid the imposition of the excise
tax.

     Compensation policies in the event of a change in control are reviewed
regularly to ensure that the policies reflect terms and conditions consistent
with those adopted by comparable companies and that are in our best interests.
The Board of Directors or the GN&C Committee may change such policies as the
facts and circumstances dictate.

              PROPOSAL 2: RATIFICATION OF APPOINTMENT OF AUDITORS

     Pursuant to the recommendation of the Audit Committee, the Board of
Directors appointed KPMG LLP, independent public accountants, to audit our
consolidated financial statements for the year ending December 31, 2003. KPMG
LLP has audited our consolidated financial statements since 1989. We are advised
that no member of KPMG LLP has any direct or material indirect financial
interest in NATCO or, during the past three years, has had any connection with
us in the capacity of promoter, underwriter, voting trustee, director, officer
or employee.

     Ratification of this appointment shall be effective upon receiving the
affirmative vote of the holders of a majority of the voting stock present or
represented by proxy and entitled to vote at the annual meeting.

     THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR RATIFICATION OF THIS
APPOINTMENT.

     In the event the appointment is not ratified, the Board of Directors will
consider the appointment of other independent auditors. Representatives of KPMG
LLP are expected to be present at the annual meeting and

                                        17


will be offered the opportunity to make a statement if they desire to do so. The
representatives of KPMG LLP also will be available to answer questions and
discuss matters pertaining to the Report of Independent Auditors contained in
the audited financial statements in our Annual Report on Form 10-K for the year
ended December 31, 2002.

            SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Section 16(a) of the Securities Exchange Act of 1934 requires our executive
officers and directors, and persons who own more than 10% of our common stock,
to file certain beneficial ownership reports with the Securities and Exchange
Commission. Based solely on our review of copies of such reports received by us
and representations from certain reporting persons, we believe that during 2002,
all of our directors, executive officers and beneficial owners of more than 10%
of our common stock complied with all applicable Section 16(a) filing
requirements applicable to them, except as disclosed in this paragraph. During
2002, one filing related to the automatic conversion of Mr. Hickox's Class B
common stock to Class A common stock (changing the form of ownership from
derivative to non-derivative, but not the number of shares previously reported)
was submitted on an untimely basis.

                                 OTHER BUSINESS

     We have no knowledge of any business to be presented for consideration at
the meeting other than that described above. If any other business should
properly come before the annual meeting or any adjournments thereof, it is
intended that the shares represented by proxies will be voted in accordance with
the judgment of the persons named in the proxies.

     COPIES OF NATCO GROUP INC.'S 2002 ANNUAL REPORT TO STOCKHOLDERS, INCLUDING

     Proposals of stockholders intended to be presented at the 2004 annual
meeting of stockholders must be received by us at our principal executive office
by December 23, 2003, in order for such proposals to be included in our proxy
statement and form of proxy for such meeting. Stockholders submitting such

                                        18


     In addition, our bylaws provide that only such business as is properly
brought before the 2004 annual meeting of stockholders will be conducted. For
business to be properly brought before the meeting or nominations of persons for
election to the Board of Directors to be properly made at the annual meeting by
a stockholder, notice must be received by the Secretary at our principal
executive offices not later than the close of business on the 40th day prior to
the annual meeting. The notice to us must also provide certain information set
forth in the bylaws. A copy of the bylaws may be obtained upon written request
to the Secretary.

          ALL STOCKHOLDERS ARE URGED TO COMPLETE, SIGN AND RETURN THE
               ACCOMPANYING PROXY CARD IN THE ENCLOSED ENVELOPE.
