        4.  To  transact  such other  business as may  properly  come before the
            meeting.

        Only  stockholders of record at the close of business on April 18, 2003,
the record date fixed by the Board of Directors,  are entitled to notice of, and
to vote at, said meeting.



                                                         Gary J. Morgan,

        Whether or not you plan to attend the meeting,  please sign and date the
enclosed proxy, which is solicited by the Board of Directors of the Company, and
return it to the  Company.  The proxy may be  revoked  at any time  before it is
voted, and stockholders  executing proxies may attend the meeting and vote there
in person, should they so desire.




                               MET-PRO CORPORATION
               160 Cassell Road, Harleysville, Pennsylvania 19438


                                 PROXY STATEMENT

        The  Board  of  Directors  of  Met-Pro  Corporation  (the  "Company"  or
"Met-Pro")  presents this proxy statement to all stockholders and solicits their
proxies for the Annual Meeting of  Stockholders to be held on June 11, 2003. All
proxies duly executed and received will be voted on all matters presented at the
meeting in  accordance  with the  specifications  made in such  proxies.  If the
Met-Pro shares that you own are  registered in the name of your broker  ("street
name"),  your broker,  in the absence of specific  instructions  from you on the
proxy  card,  will  vote  your  shares  in favor of the  named  nominees  to the
Company's Board of Directors and the ratification of the selection of Margolis &
Company P.C. as independent certified public accountants. However, if you do not
specifically  indicate on the proxy card that you vote in favor of the  approval
of the  change  of  the  Company's  state  of  incorporation  from  Delaware  to
Pennsylvania,  your broker will not be permitted to vote on this proposal, which
will have the effect of being a vote  against  this  proposal.  If your  Met-Pro
shares are  registered  directly in your name,  in the absence of your  specific
vote on the proxy card, your shares will be voted in favor of the named nominees
to the Company's Board of Directors and in favor of each of the other proposals.
Management  does not know of any other  matters  that may be brought  before the
meeting nor does it foresee or have reason to believe  that proxy  holders  will
have to vote for a substitute or alternate nominee.  In the event that any other
matter  should  come  before the  meeting or any  nominee is not  available  for
election,  the  persons  named in the  enclosed  proxy  will have  discretionary
authority  to vote all proxies not marked to the  contrary  with respect to such
matters in accordance with their best judgment.  The proxy may be revoked at any
time  before  being  voted by  written  notice to such  effect  received  by the
Company,  160  Cassell  Road,   Harleysville,   Pennsylvania  19438,  attention:
President,  prior to exercise of the proxy, by delivery of a later proxy or by a
vote cast in person at the meeting.  The Company will pay the entire  expense of
soliciting these proxies, which solicitation will be by use of the mail.

        The total number of shares of Common Stock of the Company outstanding as
of April  18,  2003  was  6,216,369.  The  Common  Stock  is the  only  class of
securities  of the Company  entitled to vote,  each share being  entitled to one
noncumulative  vote. Only  stockholders of record as of the close of business on
April 18, 2003 will be entitled to vote. Directors are elected by a plurality of
the votes cast.  In order to be approved,  the proposal to change the  Company's
state of  incorporation  from Delaware to  Pennsylvania  must be approved by the
affirmative  vote of the  holders of a  majority  of the  outstanding  shares of
Common  Stock of the  Company.  Other  matters  to be voted  upon at the  Annual
Meeting are  determined by a majority of the votes cast.  Shares  represented by
proxies that are marked "withhold authority" with respect to the election of one
or more  nominees as  Directors,  by proxies that are marked  "abstain" on other
proposals,  and by proxies  that are marked to deny  discretionary  authority on
other matters that may be properly brought before the meeting will be counted as
present for quorum  purposes  but will not be counted in  determining  whether a
majority  vote was  obtained in such  matters.  In instances  where  brokers are
prohibited from  exercising  discretionary  authority for beneficial  owners who
have not returned proxies to the brokers (so-called "broker  non-votes"),  those
shares will be counted as present for quorum  purposes  but will not be included
in the vote totals and, therefore, will have no effect on the vote.

        A list of stockholders entitled to vote at the meeting will be available
at the Company's offices,  160 Cassell Road,  Harleysville,  Pennsylvania 19438,
for a  period  of  ten  days  prior  to  the  meeting  for  examination  by  any
stockholder.

        These proxy  materials were first mailed to  stockholders of the Company
on or about April 28, 2003.



                                 PROPOSAL NO. 1
                              ELECTION OF DIRECTORS

        The  Company's  Restated  Certificate  of  Incorporation,   as  amended,
provides for a classified Board of Directors,  with the Board divided into three
classes whose terms expire at different  times.  At the meeting,  two Directors,
Alan Lawley and Gary J. Morgan,  whose terms of office expire with this meeting,
will be  nominated  for  re-election  for terms that  expire at the 2006  Annual
Meeting.  Information regarding the Board's two nominees is set forth on page 2.
Information  regarding  the  Directors  whose  terms do not expire with the 2003
Annual Meeting is also set forth on pages 2 and 3.

        Unless otherwise  indicated in valid proxies  received  pursuant to this
solicitation,  such proxies will be voted for the election of the persons listed
below as nominees  for the terms set forth  below.  Management  has no reason to
believe  that the  nominees  will not be available or will not serve if elected.
These  proxies  may not be voted for more than two  persons.  If either  Messrs.
Lawley  or  Morgan  should  become  unavailable  to  serve as a  Director,  full
discretion  is reserved  to the persons  named as proxies to vote for such other
person as may be nominated.

        The  following  sets forth  certain  information  as to the nominees for
election  as  Directors  and for each  other  person  whose  term of office as a
Director will continue after this Annual Meeting of Stockholders:

                       BOARD AND BOARD COMMITTEE MEETINGS

        The Board of  Directors of the Company  held seven  meetings  during the
fiscal year ended January 31, 2003.

        The Audit Committee of the Board of Directors is composed of Mr. Morris,
Chairman, Dr. Lawley and Mr. DeBenedictis. The Board of Directors of Met-Pro has
determined  that each of the members of the Audit  Committee is  independent  of
management of Met-Pro and is free of any relationship  that would interfere with
his exercise of independent  judgment as a committee member. The Audit Committee
met four times  during  fiscal  year 2003,  with two of such  meetings  being by
telephonic conference call.

        The  focus of the  Audit  Committee  is upon:  (i) the  adequacy  of the
Company's internal controls and financial  reporting process and the reliability
of the Company's financial statements;  (ii) the independence and performance of
the Company's  independent  auditors;  and (iii) the Company's  compliance  with
designated legal and regulatory requirements.  Further information regarding the
functions  of the  Audit  Committee  are set forth in the  "Report  of the Audit
Committee" below and "Audit  Committee  Charter" which is included as Appendix A
to this Proxy Statement.

        The Compensation  and Stock Option  Committee of the Board,  composed of
Dr. Lawley, Chairman, Mr. Morris and Mr. DeBenedictis, reviews and recommends to
the Board appropriate action with respect to all matters pertaining to officers'
compensation  as well as stock option grants for  Directors,  officers and other
key  employees of the Company.  See the  Committee's  report on pages 8 and 9 of
this proxy statement.  The Compensation and Stock Option Committee met two times
in fiscal year 2003.

        Each Director of the Company attended all the meetings held by the Board
of Directors and by the Committees on which he served.

        The Company does not have a standing  nominating  committee charged with
the search for and  recommendation to the Board of potential  nominees for Board
positions.  This function is performed by the Board as a whole. It has been, and
continues to be, the Board's policy to entertain stockholder recommendations for
prospective  Board nominees.  Any such  recommendations  may be submitted to the
Board, in writing, addressed to the Chairman.

        Until  such  time  as  a  majority  of  the  Company'  s  Directors  are
"independent Directors" within the meaning of applicable New York Stock Exchange
and other  applicable  requirements,  the Board has adopted a policy that in any
contested  vote in which  the vote of the  independent  Directors  as a group is
contrary to the vote of the  non-independent  Directors as a group,  the vote of
the independent  Directors shall prevail.  For purposes of this policy,  Messrs.
Kacin,  De Hont,  Morgan and Nicholas are each  considered not to be independent
Directors.



                          REPORT OF THE AUDIT COMMITTEE

        The Audit Committee reviews the Company's financial reporting process on
behalf of the Board of Directors.  Management has the primary responsibility for
the  financial  statements  and the reporting  process,  including the system of
internal controls.

        In  this  context,  the  Committee  has met and  held  discussions  with
management and the independent auditors. Management represented to the Committee
that the Company's consolidated financial statements were prepared in accordance
with generally accepted  accounting  principles,  and the Committee has reviewed
and discussed the  consolidated  financial  statements  with  management and the
independent  auditors.  The Committee  discussed with the  independent  auditors
matters  required to be  discussed by  Statement  on Auditing  Standards  No. 61
(Communication With Audit Committees).

        In addition,  the Committee has discussed with the independent  auditors
the auditors'  independence  from the Company and its management,  including the
matters in the written disclosures required by the Independence  Standards Board
Standard No. 1 (Independence  Discussions With Audit Committees).  The Committee
has also considered  whether the independent  auditors' other non-audit services
to the Company are compatible with the auditors'  independence and has concluded
that they are.

        Prior to the commencement of the audit, the Committee discussed with the
Company's  independent auditors the overall scope and plans for their respective
audits. The Committee meets with the independent auditors to discuss the results
of their examinations,  the evaluations of the Company's internal controls,  and
the overall quality of the Company's financial reporting.

        In  reliance  on the reviews  and  discussions  referred  to above,  the
Committee  and the  Board of  Directors  have  recommended,  and the  Board  has
approved,  that the audited  financial  statements  be included in the Company's
Annual  Report on Form 10-K for the fiscal  year ended  January  31,  2003,  for
filing with the Securities and Exchange Commission.  The Committee and the Board
also have recommended the selection of the Company's independent auditors.

                            INDEPENDENT AUDITORS FEES

Audit Fees

        The  aggregate  fees  billed by Margolis & Company  P.C.  for the annual
audit of Met-Pro's  consolidated  financial statements for the fiscal year ended
January 31, 2003 and the reviews of the Company's Quarterly Reports on Form 10-Q
for the same fiscal year were $94,100.

All Other Fees

        The aggregate fees billed by Margolis & Company P.C. for other services,
which  pertain  to audits of our  employee  benefits  plans and  preparation  of
corporate  income tax returns,  for the fiscal year ended  January 31, 2003 were
$44,500. The Audit Committee has considered whether the provision of these other
services by Margolis & Company P.C. is compatible with maintaining the principle
independent auditors independence and has concluded that they are independent.



                            COMPENSATION OF DIRECTORS

        The present  policies of the Board as to  Director  compensation  are as
follows: non-employee Directors receive (i) a retainer of $10,000 per year, paid
quarterly;  (ii) a meeting fee of $1,250 for each Board meeting (but no fees for
special  telephone  meetings  or for  stockholders  meetings)  and $700 for each
Committee meeting;  and (iii) an annual stock option grant of up to 5,000 shares
of Common  Stock of the Company on terms that are  intended to be  substantially
similar to the terms of the options  granted to the  Company's  officers.  These
terms, which the Board has the authority to change from time to time, subject to
the terms of the Company's  stock option plans, in general,  are as follows:  an
exercise  price that is equal to the market price of the Company's  Common Stock
on the date of grant;  a vesting  period of two  years,  with  one-third  of the
shares covered by the option being immediately exercisable;  provided,  however,
in the event of a "change of control",  any unvested portion of the option shall
become  immediately  exercisable.  The term of the option shall be for up to ten
years, subject to earlier termination under various conditions.  Those Directors
who are  employees  of the  Company do not receive  any  compensation  for their
services as Directors.

        In connection with this, on February 24, 2003, the Board granted options
on the foregoing terms to purchase 5,000 shares to Messrs. DeBenedictis, Lawley,
Morris and Nicholas at the average of the high and low of the  Company's  Common
Stock as quoted on the New York Stock  Exchange on February 24, 2003,  or $13.08
per share.

        The  Board's  current  policy  as to an  annual  grant  of  options  for
non-employee  Directors  was  intended to replace  participation  by  non-vested
Directors in the Directors'  Retirement  Plan that the Board had  established in
1994 (the "Directors'  Plan"). Of the Company's current Directors,  only Messrs.
Kacin and Lawley will receive  benefits in the future under the Directors'  Plan
as a result of the fact that each such  person  was  vested as of  December  16,
1999, the date of the Board's action on this plan. The accrual of benefits under
the  Directors'  Plan for Dr. Lawley ceased as of December 16, 1999, in that Dr.
Lawley  elected to receive  options as  aforementioned  for  continued  Director
service in lieu of participation under the Directors' Plan. The Directors' Plan,
which was  established  in 1994,  provides that Directors who have completed six
years of service will be eligible to receive  deferred  compensation  after they
cease to serve or reach age 70,  whichever last occurs.  Payment will be made in
annual  installments based on $1,000 for each year of service as a Director,  up
to a maximum of $10,000 and for a period equal to the length of service, up to a
maximum  of 15  installments.  Directors  who have  served as a Chief  Executive
Officer  for at least six years will be eligible  to receive  additional  annual
deferred  compensation  at the rate of  $1,000  for each year of  service  as an
officer and/or Director,  up to a maximum of $20,000,  for a period equal to the
length  of such  service,  up to  twenty  years.  In the  event of death  before
payments have been completed, the remaining annuity payments will be paid to the
Director's surviving spouse. If there is no surviving spouse, a lump sum payment
will be paid to the Director's  estate equal to the sum of ten annual retirement
payments, less the total paid prior to death.

        The Directors' Plan further  provides that if a Director's  services are
terminated  at or after a "change in control" of the  Company,  the  Director is
entitled to an immediate  lump sum payment of the benefits  then  applicable  to
such Director,  and future payments due under the Plan to former Directors shall
be  accelerated  and shall be immediately  due and payable.  For purposes of the
Plan,  a "change in control"  shall be deemed to occur if any person or group of
persons  as defined  shall  become  the  beneficial  owner of 30% or more of the
Company's  voting  securities,  or  there  shall  be a  change  in the  majority
composition  of a  Company's  Board of  Directors,  or the  stockholders  of the
Company  shall  approve a merger or other  similar  reorganization  in which the
persons  who  were  stockholders  of the  Company  prior to such  merger  do not
immediately  thereafter  own  more  than  50% of the  voting  securities  of the
Company,  or in the  event  of a change  of  control  as  defined  in any  other
agreement or plan of the Company.

             SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

        Section  16(a)  of the  Securities  Exchange  Act of 1934  requires  the
Company's  Directors and executive  officers,  and persons who own more than ten
percent of a registered  class of the Company's  equity  securities to file with
the Securities and Exchange  Commission initial reports of ownership and reports
of changes in  ownership  of Common  Stock and other  equity  securities  of the
Company.  Officers,  Directors  and greater  than ten percent  stockholders  are
required  by  Securities  and  Exchange  Commission  regulations  to furnish the
Company with copies of all Section 16(a) forms that they file.

        Based  solely upon a review of the copies of the forms  furnished to the
Company, or written representations from certain reporting persons that no Forms
5 were required, the Company believes that all filing requirements applicable to
its  officers  and  Directors  were  complied  with during the fiscal year ended
January 31, 2003.

                     COMPENSATION AND STOCK OPTION COMMITTEE
                        REPORT ON EXECUTIVE COMPENSATION

        The  Compensation   and  Stock  Option   Committee  (the   "Compensation
Committee" or "Committee") is composed only of independent  non-employee members
of the Board of Directors.  The Committee makes  recommendations to the Board of
Directors  (the  "Board")  concerning  compensation  policies for the  Company's
executive  officers and  Directors.  The Committee  makes every effort to ensure
that the Company's compensation program is consistent with the values of Met-Pro
Corporation and furthers its business strategy.

        The  Compensation  Committee has  established a  compensation  plan (the
"Management  Incentive  Plan")  applicable to the Chief Executive  Officer,  the
Chief Operating Officer, the Chief Financial Officer, and the operating officers
of the Company's divisions and subsidiaries  (herein  collectively  "divisions")
who  generally  have  the  title  of  Vice   President/General   Manager.   This
compensation policy is based upon three primary components:  salary; eligibility
for a bonus; and eligibility for an award of stock options. These components are
intended to facilitate fulfillment of the following compensation objectives: (i)
aligning the interests of management  with those of the Company's  stockholders;
(ii) retaining competent  management;  (iii) relating executive  compensation to
the  achievement  of the  Company's  goals and financial  performance;  and (iv)
rewarding management for the attainment of short and long-term accomplishments.

        Consistent with these objectives,  in adopting the Management  Incentive
Plan, the Board,  following the Committee's  recommendations,  set salary ranges
for each of the various officer positions.  In establishing these salary ranges,
as well as in determining  the other features of the Management  Incentive Plan,
the  Committee  drew in part  upon the  data  supplied  to it by an  independent
consulting  firm.  The  Committee  periodically  reviews,  and  as  appropriate,
modifies these salary  ranges.  On an annual basis,  the Committee  requests the
Chief Executive Officer to make salary  recommendations  for the officers of the
Company (other than himself) within these ranges.

        Under the  terms of the  Management  Incentive  Plan  instituted  by the
Board, in order to be eligible for a bonus,  certain objective threshold results
must be met. For Vice Presidents/General Managers of divisions, the threshold is
the attainment of a stated operating  income for the division(s)  managed by the
Vice President/General Manager. For the Company's Chief Executive Officer, Chief
Operating Officer and Chief Financial  Officer,  the threshold is the attainment
of a stated  earnings per share result for the Company for the fiscal year. Each
officer's  bonus  eligibility  levels are  considered  and set by the  Committee
during a meeting held following the completion of the Company's annual budgeting
process and are tied to the operating  plan that the Board approves on an annual
basis prior to the commencement of the fiscal year. In the event of a failure to
attain the threshold figure, the officer is not eligible for a bonus.

        The  incentive  levels of the bonuses are at stated  percentages  of the
year's salary that increase with  responsibility.  If the threshold  performance
goal has been attained so as to qualify the  executive  for a bonus,  the actual
amount of the bonus is a function of attainment of other stated goals, such as a
stated net sales figure, a stated  operating income figure,  and stated personal
objectives,  which can be  "quantitative",  such as being  linked  to  inventory
turnover or accounts receivable days outstanding, as well as "qualitative", such
as being linked to improved divisional leadership. The Management Incentive Plan
further  provides that each of the stated goals is assigned a stated  percentage
set by the Chief Executive  Officer within a stated range set by the Board.  The
percentages  for  the  Chief  Executive  Officer  are  set by  the  Compensation
Committee.

        The Committee  notes that the Management  Incentive Plan provides for an
accrual of the bonus amount in the reported results of operations for the fiscal
year to which the bonus relates.

        As to the  stock  option  component  of the  Management  Incentive  Plan
adopted  by the  Board,  the  Chief  Executive  Officer  is  requested  to  make
recommendations  as to the  award  to the  Company's  officers  (other  than for
himself) of stock options up to a stated maximum amount per year, subject to the
maximum grant amounts that the Board has set for each of the officer  positions.
The Committee  views stock  options as an incentive  for long term  performance.
Subject  to this,  the  Committee's  approach  is to  consider  a grant of stock
options in part in the context of the level of performance  demonstrated  by the
officer  during the  fiscal  year most  recently  ended.

                                       8


        It is the Committee's present practice to meet following the end of each
fiscal year in order to review any bonuses payable under the eligibility  levels
of the  Management  Incentive  Plan that were set prior to the beginning of such
fiscal year,  set salaries  for the current  fiscal year,  consider the grant of
stock options, and take other action as it deems appropriate.

        At its meeting following the completion of the fiscal year ended January
31, 2003, the Committee,  after discussing with the Chief Executive  Officer his
recommendations as to salary increases and stock option awards for the Company's
officers  other than for himself,  substantially  accepted  the Chief  Executive
Officer's recommendations. The salary increases and stock option awards that the
Committee  has approved are within the ranges  previously  approved by the Board
and are based in part upon current data  supplied by an  independent  consulting
firm regarding executive  compensation  practices of other comparable companies.
The Committee  provided  incentive for  long-term  performance  with an award of
stock options  aggregating  an amount  similar in number to the prior year.  The
Committee has  determined to grant a bonus outside of the  Management  Incentive
Plan to Mr.  Morgan to reflect  contributions  to the Company  during the fiscal
year.  The  Committee  has  established  a salary for and awarded  stock options
within the  guidelines  to Mr. De Hont in order to reflect  his  election as the
Company's Chief Executive Officer effective March 1, 2003, and has established a
salary and awarded stock options  within the  guidelines  and the Company's past
practices  to Mr.  Kacin in order to take into  account  his  leadership  of the
Company  during a time of management  transition  and the nature of his expected
continued role in the Company.

Stock Option Plans

        The  Company's  1997 Stock  Option Plan (the "1997 Plan") was adopted by
the  Company's  Board of Directors  on February  24,1997 and was approved by the
stockholders  on June 4, 1997.  The Company's  2001 Stock Option Plan (the "2001
Plan") was adopted by the Company's Board of Directors on February 26, 2001, and
was approved by the  stockholders  on June 20, 2001. An aggregate of 445 options
for the Company's Common Stock are presently  available for grant under the 1997
Plan,  and an aggregate of 221,700  options for the  Company's  Common Stock are
presently available for grant under the 2001 Plan, plus an indeterminate  number
of additional shares resulting from anti-dilution adjustments.

        These  Plans  provide for the grant of  options,  which are  intended to
satisfy the requirements of Section 422 of the Internal Revenue Code of 1986, as
well as options which are not intended to satisfy such requirements.

        The following table sets forth stock options granted for the fiscal year
ended January 31, 2003 to each of the Company's  executive officers named in the
Summary  Compensation  Table and stock  options  granted to all  employees  as a
group. The table also sets forth the hypothetical gains that would exist for the
options at the end of their ten-year  terms for the executive  officers named in
the Summary  Compensation Table and for all employees as a group (assuming their
options had ten year terms) at assumed  compound rates of stock  appreciation of
5% and 10%.  The actual  future  value of the options  will depend on the market
value of the Company's  Common Stock.  All options  exercise prices are based on
market price on the date of grant.

Termination of Employment and Change of Control Arrangements

        Mr.  De Hont is party to a Key  Employee  Severance  Agreement  with the
Company which provides that in the event the Company  terminates his employment,
other than for cause, within eighteen months following a "change of control", or
if Mr. De Hont  voluntarily  terminates such  employment  within eighteen months
subsequent to a "change of control", the Company shall be obligated to pay him a
sum of money equal to two years' of base compensation.  Payment would be made in
a lump sum upon cessation of employment  or, at Mr. De Hont's  option,  in equal
monthly  installments  over a two-year period.  The base annual salary currently
payable to Mr. De Hont is $240,000.

        Mr. Morgan is also party to a Key Employee Severance  Agreement on terms
that are  identical  to those to which  Mr. De Hont is  party,  except  that the
amount of  compensation is equal to eighteen  months of base  compensation.  Mr.
Morgan's base annual salary is currently $170,000.

        The Directors' Plan also provides for the payment of certain benefits in
the event of a "change of  control",  as discussed  under  "Board and  Committee
Participation/Compensation  of  Directors"  elsewhere  herein.  In addition,  as
disclosed in such section of this Proxy  Statement,  the Company's  stock option
agreements  provide for the immediate vesting of all unvested stock options upon

401(k) Profit Sharing Plan

match,  in the  form  of  Met-Pro  Common  Stock,  up to  50% of the  employee's
contribution up to 4% of  compensation.  During the Company's three fiscal years
ended January 31, 2003, the Company made contributions to the 401(k) Plan in the
amount of $9,184 for William L. Kacin, $9,537 for Raymond J. De Hont, $9,330 for
Gary J. Morgan,  $7,962 for William F. Mersch,  $6,917 for Thomas V. Edwards and

        Pursuant to the Company's  Salaried  Employee Stock  Ownership Plan (the
"Ownership  Plan"),  the Company  may make  discretionary  contributions  to the
Company's  Salaried  Employee Stock Ownership Trust (the "Trust") either in cash
or in Company Common Stock. The Trust uses the cash  contributions and dividends
received  to  purchase  shares of the  Company's  Common  Stock.  All  full-time
salaried  employees  who are at least 21 years of age and who have been employed
by the  Company  on a full-  time  basis for at least one year are  eligible  to
participate  in the  Ownership  Plan.  All  shares  acquired  by the  Trust  are
allocated  to the  accounts  of  eligible  employees  based on their  respective
salaries. Employees nearing retirement have discretion to diversify a portion of
their  investment.  There were no contributions by the Company to the Employee's
Stock Ownership Trust in fiscal years ended in 2003, 2002 and 2001.

Pension Plans

        The  Salaried  Pension  Plan  (the  "Retirement   Plan")  is  a  funded,
tax-qualified  noncontributory  defined benefit pension plan that covers certain
employees, including the Named Executive Officers. Benefits under our Retirement
Plan are  calculated  as an annuity of one  percent of the  participant's  final
average  earnings for the five highest  consecutive  years of the last ten years
multiplied by year of service.  Earnings  covered by the Retirement Plan include
annual salary and cash bonus paid pursuant to the Company's Management Incentive
Plan.  The  amount of annual  earnings  that may be  considered  in  calculating
benefits  under the  Retirement  Plan is  limited by law.  For 2003,  the annual
limitation is $200,000.

        Effective  February 1, 2000,  the Board of  Directors  adopted a Pension
Restoration  Plan for  Messrs.  Kacin and  Morgan.  Mr. De Hont was added to the
Pension  Restoration  Plan effective  February 1, 2001. The Pension  Restoration
Plan is an unfunded supplemental plan that provides out of our general assets an
amount  substantially equal to the difference between the amount that would have
been payable under the Retirement  Plan, in the absence of legislation  limiting
pension  benefits and earnings  that may be considered  in  calculating  pension
benefits, and the amount actually payable under the Retirement Plan.

        The  following  table shows the  estimated  annual  Retirement  Plan and
Pension  Restoration  Plan benefits on a straight life (no death  benefit) basis
payable for various earnings levels upon retirement at age 65, after 15, 20, 25,
30 and 35 years of credited service to the Company:

(a)  Internal Revenue Code Section 401(a)(17) limits earnings  used to calculate
     Retirement Plan benefits totaled $200,000 for 2001 and 2002, respectively.

        As of January 31, 2003,  Messrs.  Kacin,  De Hont and Morgan had accrued
26, 7 and 22 years service  under the  Retirement  Plan and the related  Pension
Restoration Plan. Messrs. Mersch and Edwards each had accrued 7 years of service
under the Retirement Plan for this same period.

        In 2000,  the Company  established a Supplemental  Executive  Retirement
Plan ("SERP") for Mr. Kacin.  This Plan,  which is a non-qualified  and unfunded
plan,  was  approved  by the Board of  Directors  and is intended to provide Mr.
Kacin with a total retirement  benefit, in combination with the Retirement Plan,
Pension  Restoration  Plan  and  Directors  Retirement  Pension  Plan,  that  is
commensurate  with the retirement  benefits for the Chief Executive  Officers of
other  comparable  companies.  Under the terms of the SERP,  Mr.  Kacin  will be
eligible to receive  benefits under the SERP at normal  retirement  equal to the
difference  between  (i) the  monthly  benefit  that would be payable  under the
Retirement  Plan,  except that the amount shall be determined  without regard to
the ERISA limitations and the one percent benefit in the Retirement Plan will be
replaced with a two percent  benefit and (ii) the benefits  payable to Mr. Kacin
under the Retirement Plan, Pension Restoration Plan,  Directors Pension Plan and
Social Security retirement benefit.

        The Company utilized the services of the law firm of Fox Rothschild LLP,
during the fiscal year ended January 31, 2003.  Jeffrey H. Nicholas,  a Director

                                 PROPOSAL NO. 2
         APPROVAL OF THE CHANGE IN THE COMPANY'S STATE OF INCORPORATION
                          FROM DELAWARE TO PENNSYLVANIA

        At the  Annual  Meeting,  you will be asked to vote upon a  proposal  to
change the Company's state of incorporation from Delaware to Pennsylvania.  This
is commonly called a "reincorporation".

        The principal reason for  reincorporating the Company in Pennsylvania is
to eliminate the Company's  annual  liability under the Delaware  franchise tax,
which amounted to $31,600 for the twelve-month  period ended January 31, 2003. A
secondary   consideration   is  the  Board's  belief  that  the  differences  in
stockholder  rights and the powers of management under Pennsylvania and Delaware
law provide  desirable  flexibility in the management of the Company and enhance
the Board's ability to pursue the long-term interests of the stockholders of the
Company and the other constituencies served by the Company.

        At one time, the Delaware  General  Corporation Law (the "Delaware GCL")
was  generally  viewed  as  being  more  modern  and less  restrictive  than the
corporation laws of Pennsylvania. However, the Company believes that many of the
differences  between  the  Delaware  and  Pennsylvania   corporation  laws  were
eliminated  several years ago when Pennsylvania  adopted sweeping changes in the
Pennsylvania  Business  Corporation law (the  "Pennsylvania  BCL") that afforded
Pennsylvania corporations significant operating flexibility.

        As a  result  of  the  large  number  of  corporations  incorporated  in
Delaware, the Delaware courts have developed a considerable expertise in dealing
with  corporate  issues  and a  substantial  body  of  case  law  has  developed
construing  Delaware  law and  establishing  public  policies  with  respect  to
Delaware  corporations.  The Board of Directors believes,  however, that the tax
savings and other advantages of reincorporating  in Pennsylvania  outweigh these
benefits of being incorporated in Delaware.

        If approved,  this  reincorporation  will be accomplished by merging the
Company into a wholly-owned  Pennsylvania subsidiary that was recently formed by
the Company solely for the purpose of effecting the reincorporation, referred to
as the  "merger".  The  Company  as  currently  incorporated  in  Delaware  will
sometimes   be  referred  to  as   "Met-Pro   Delaware",   and  the  Company  as
reincorporated in Pennsylvania will be referred to as "Met-Pro Pennsylvania".

        THE REINCORPORATION WILL NOT RESULT IN ANY CHANGE IN THE NAME, BUSINESS,
MANAGEMENT,  BENEFIT PLANS, LOCATION,  ASSETS,  LIABILITIES,  NET WORTH, CAPITAL
STRUCTURE OR NUMBER OF PRESENTLY ISSUED AND OUTSTANDING SHARES OF THE COMPANY.

        On the effective date of the merger,  each  outstanding  share of common
stock of Met-Pro  Delaware  will  automatically  be converted  into one share of
common stock of Met-Pro Pennsylvania,  and stockholders of Met-Pro Delaware will
become  shareholders  of  Met-Pro  Pennsylvania.  IT WILL NOT BE  NECESSARY  FOR
STOCKHOLDERS  OF THE COMPANY TO EXCHANGE  THEIR  EXISTING  CERTIFICATES  FOR NEW
CERTIFICATES  REPRESENTING COMMON SHARES OF MET-PRO  PENNSYLVANIA.  Certificates
that   previously   represented   Company  common  stock  will  be  replaced  by
certificates  representing  common  shares  of  Met-Pro  Pennsylvania  only when
submitted  to the  transfer  agent for  transfer or with a request  that they be
replaced.  Upon  completion  of the merger,  certificates  for shares in Met-Pro
Delaware  will  automatically  represent  an equal  number of  common  shares of
Met-Pro Pennsylvania.

        The merger will be effected  pursuant to the terms and  conditions of an
Agreement and Plan of Merger, which is referred to as the "merger agreement",  a
copy of which is included as Appendix B to this proxy statement.

        The  reincorporation  will  effect  certain  changes in your rights as a
shareholder  primarily  as a result of (i)  differences  between the Articles of
Incorporation  (the  "Pennsylvania  Articles")  and  Bylaws  (the  "Pennsylvania
Bylaws") of Met-Pro  Pennsylvania and the Restated Certificate of Incorporation,
as amended (the  "Delaware  Certificate")  and Bylaws as amended (the  "Delaware
Bylaws") of the Company,  (ii) differences  between the Pennsylvania BCL and the
Delaware GCL and (iii) as a result of other differences referred to herein.

        Copies of the  Pennsylvania  Articles  and the  Pennsylvania  Bylaws are
included as Appendices C and D to this proxy  statement.  Copies of the Delaware
Certificate  and  Delaware  Bylaws as  currently  in effect  are  available  for
inspection at the  headquarters  of the Company and will be sent to stockholders
without cost upon request. The Delaware GCL refers to "stockholder"  whereas the
Pennsylvania  BCL uses  the term  "shareholder".  The term  shareholder  is used
throughout the discussion below because "stockholder" and "shareholder" have the
same meaning under those statutes.

        The merger  agreement  was  approved by  unanimous  vote of the Board of
Directors of the Company at its meeting on April 2, 2003. Under Delaware law and
the  Delaware  Certificate,  consummation  of the merger will  require  that the
merger  agreement be adopted by the affirmative vote of the holders of record of
a majority of the outstanding shares of common stock of the Company.  The merger
and  reincorporation  will be effected as soon as  practicable  after the merger
agreement has been approved by the shareholders.  The merger and reincorporation
may be abandoned or the merger agreement may be amended,  either before or after
shareholder   approval,   if,  in  the  opinion  of  the  Board  of   Directors,
circumstances  arise  that  make  it  inadvisable  to  proceed.  However,  after
shareholder  approval,  the  principal  terms of the  merger  may not be amended
without further shareholder approval. If the merger agreement is not approved by
the shareholders, the merger and reincorporation will not be consummated and the
Company will remain a Delaware corporation.

     COMPARATIVE RIGHTS OF SHAREHOLDERS BEFORE AND AFTER THE REINCORPORATION

General

        In general,  the rights of  shareholders  of  Pennsylvania  and Delaware
business  corporations  are  governed  by and subject to the  provisions  of the
Pennsylvania  BCL and the Delaware  GCL,  respectively.  If the  reincorporation
proposal is adopted,  the rights of shareholders will be governed by and subject
to the provisions of the  Pennsylvania BCL rather than the Delaware GCL and also
will be governed by the  Pennsylvania  Articles and  Pennsylvania  Bylaws rather
than the provisions of the Delaware  Certificate and Delaware  Bylaws. A summary
of the material  differences in the rights of shareholders  before and after the
reincorporation  follows.  Although the summary below discusses the Pennsylvania
Articles,  the  Pennsylvania  Bylaws,  the  Delaware  Certificate,  the Delaware
Bylaws,  the  Pennsylvania  BCL and the Delaware GCL, this  discussion  contains
neither an exhaustive  description of all differences  between the  Pennsylvania
Articles  and  Pennsylvania  Bylaws and the  Delaware  Certificate  and Delaware
Bylaws nor an exhaustive  description of the differences between the laws of the
two states, and is qualified by the actual terms of those documents and laws.

Fundamental Corporate Transactions; Amendments to Charter

        The Delaware Certificate provides that if a majority of the entire Board
of Directors of the Company has approved certain  fundamental  transactions such
as a merger or sale of  substantially  all of the  assets,  the  approval of the
holders of a majority of the  outstanding  shares entitled to vote on the matter
is needed to approve  the  transaction.  If,  however,  a majority of the entire
Board  of  Directors  has  not  approved  the  transaction,  then  the  Delaware
Certificate  requires  the  approval  of  the  holders  of at  least  80% of the
outstanding  shares to approve the  transaction.  The Delaware  Certificate also
requires approval by the holders of at least 80% of the outstanding  shares of a
transaction  involving the purchase of stock or assets of another corporation in
exchange  for shares of the  Company's  stock,  unless a majority  of the entire
Board of Directors has approved the transaction.  The Pennsylvania  Articles are
similar to the Delaware Certificate in respect of the foregoing.

        Amendments  to the Delaware  Certificate,  other than an amendment  that
changes the  percentage of votes  required for  shareholder  approval of a given
item,  requires the approval of a majority of the outstanding shares entitled to
vote  on the  matter.  Amendments  to the  Delaware  Certificate  to  amend  the
percentage of votes  required for  shareholder  approval of a given item require
the  approval of a majority of the  outstanding  shares  entitled to vote on the
matter  unless a majority of the entire Board of  Directors  has not approved of
the amendment, in which case the amendment requires the approval of at least 80%
of the shareholders. The Pennsylvania Articles are similar in this respect.

        The  Pennsylvania  Articles  also  provide  that  such 80%  approval  is
required in order to amend the  Pennsylvania  Articles  with  respect to (a) the
provisions of Article 6 eliminating  cumulative voting otherwise  provided under
Pennsylvania  law (similarly,  there is no cumulative  voting under the Delaware
Certificate);  (b) the provisions of Article 7 relating to right of the Board of
Directors  to adopt,  amend,  and repeal the  Bylaws  and the  requirements  for
shareholder amendments to the Bylaws (see "Amendments to Bylaws" below); (c) the
provisions  of Article 8 relating  to the lack of the right of  shareholders  to
take  action by written  consent  (see  "Shareholder  Action by Partial  Written
Consent"  below)  and the lack of the  right of  shareholders  to call a special
meeting of  shareholders;  (d) the  provisions  of Article 9 as to the number of
directors and the filling of vacancies on the Board as well as the provision for
a classified Board of Directors  (similarly,  the Delaware  Certificate provides
for a classified Board of Directors); and (e) amending the foregoing provisions.
Notwithstanding  the  foregoing,  in the event that a  majority  of the Board of
Directors approves such an amendment, or an amendment to the percentage of votes
required for approval of a given item, the Pennsylvania  Articles may be amended
by the  affirmative  vote  of a  majority  of the  votes  actually  cast  by all
shareholders then entitled to vote, as is the case with respect to amendments to
the remaining provisions of the Pennsylvania Articles. The Pennsylvania BCL does
not require  shareholder  approval  of certain  non-material  amendments  to the
articles of incorporation, such as changing the corporate name or increasing the
number of authorized shares to effectuate a stock dividend where the corporation
has only one class of shares outstanding.

Amendments to Bylaws

        The  Delaware  GCL and the  Delaware  Certificate  permit  the  Board of
Directors to alter or repeal the Delaware Bylaws.  The Delaware  Certificate and
the Delaware  Bylaws permit the  shareholders  to amend the Delaware Bylaws only
upon the affirmative vote of the holders of not less than 80% of the outstanding
shares  entitled to vote at a meeting at which such matter is considered.  Under
the  Pennsylvania  BCL,  the power of the Board of  Directors  to adopt or amend
by-law provisions on certain  specified  subjects is limited unless the power to
adopt or amend these bylaw provisions is granted to the Board in the articles of
incorporation.   The  Pennsylvania  Articles  grant  this  power  to  amend  the
Pennsylvania Bylaws to the Board of Directors. As is the case before the merger,
shareholders  may amend the  Pennsylvania  Bylaws by the affirmative  vote of at
least 80% of the votes that all shareholders are entitled to cast on the matter.

Removal of Directors

        The Delaware  Bylaws  provide that a director may be removed at any time
"without cause" by an affirmative vote of at least 80% of the outstanding shares
entitled  to  vote  at a  duly  convened  regular  or  special  meeting  of  the
shareholders.  The  Pennsylvania  Bylaws  provide for the same  "without  cause"
removal, but in addition provide that a director may be removed at any time "for
cause" by an affirmative  vote of a majority of the outstanding  shares entitled
to vote at a duly convened regular or special meeting of the shareholders.

Shareholder Action by Partial Written Consent

        Under the  Pennsylvania  BCL, if  permitted  by the  Bylaws,  any action
required  or  permitted  to be taken at a meeting of  shareholders  may be taken
without a meeting upon the consent of shareholders  who would have been entitled
to cast the minimum  number of votes that would be necessary  to  authorize  the
action at a meeting at which all shareholders  entitled to vote were present and
voting.  The Delaware GCL is similar,  except that the restriction of such right
must appear in the certificate of incorporation.  The Delaware  Certificate does
not restrict the right of  shareholders of the Company to take action by partial
written consent. Under the Pennsylvania Articles and the Pennsylvania Bylaws, no
action that is required or permitted to be taken by shareholders at an annual or
special meeting may be taken by consent of the shareholders in lieu of a meeting
of shareholders.

Shareholders Meetings

        Pennsylvania  law provides that in the event that an annual  meeting for
election of  directors  is not called and held within six months  after the date
designated in a Pennsylvania  corporation's bylaws, any shareholder may call the
meeting at any time  thereafter.  Also,  Pennsylvania  law provides that special
meetings  of  shareholders  may be  called  by the  Board of  Directors  and the
officers or other persons as may be provided in the  Pennsylvania  corporation's
bylaws.  The  Pennsylvania  BCL does not permit the shareholders of a registered
corporation  to call a special  meeting of  shareholders,  and the  Pennsylvania
Articles  expressly provide that a special meeting of shareholders may be called
only by the Board of Directors acting pursuant to the Pennsylvania corporation's
bylaws or the Chairman of the Board.

        Under  Delaware law, if the annual meeting for the election of directors
is not held within 30 days after the date  provided in a Delaware  corporation's
bylaws,  or if no date has been  designated  for a period of 13 months after the
organization of the  corporation or after its last annual meeting,  the Court of
Chancery  may  summarily  order a  meeting  to be held upon the  request  of any
shareholder or director.  Also,  Delaware law provides that special  meetings of
shareholders  may be called by the Board of  Directors or by such persons as may
be authorized by the certificate of incorporation or bylaws. The Delaware Bylaws
provide that special meetings of the shareholders may be called by the President
or  Secretary  at the  request of the Board of  Directors  or at the  request of
stockholders owning a majority of issued and outstanding stock. The Pennsylvania
Bylaws provide that special  meetings of the  shareholders may be called only by
the Board of Directors or the Chairman of the Board.  Both  Pennsylvania law and
the Delaware Certificate prohibit shareholders from calling a special meeting.

Appraisal or Dissenters Rights

        The rights of shareholders to demand payment in cash by a corporation of
the fair  value of their  shares in the event of certain  fundamental  corporate
transactions are called  dissenters  rights in Pennsylvania and appraisal rights
in  Delaware.  Under the  Pennsylvania  BCL,  dissenters  rights  are  generally
afforded to  shareholders  in the event of  corporate  actions  such as mergers,
share  exchanges,  transfers  of all or  substantially  all of the assets of the
corporation and certain other fundamental  transactions in which the corporation
is not the acquiring corporation. Under the Delaware GCL, stockholders generally
have appraisal  rights in the event of a merger but not in the event of the sale
of all or substantially all of the assets of the corporation.

        Under both  Pennsylvania  and Delaware law, certain  corporations  whose
securities  are  broadly  held or market  traded  are not  required  to  provide
dissenters or appraisal rights. The Pennsylvania BCL does not provide dissenters
rights to holders of shares  that are listed on a national  securities  exchange
such as the New York Stock Exchange, as are the Company's shares, when a plan of
merger converts the shares into shares of the acquiring, surviving, new or other
corporation (whether or not the shares of the acquiring, surviving, new or other
corporation are listed on an exchange or privately  held). The Delaware GCL does
not afford  appraisal  rights to holders of shares that are listed on a national
securities  exchange  such as the New York Stock  Exchange when a plan of merger
converts such shares into stock of the surviving corporation or stock of another
corporation  that is listed on a  national  securities  exchange,  quoted on the
Nasdaq National Market System or held of record by more than 2,000 shareholders.

Dividends

        Under  Pennsylvania  law,  a  corporation  has  the  power,  subject  to
restrictions in its bylaws, to pay dividends or make other  distributions to its
shareholders,  unless after giving effect to the  dividends (i) the  corporation
would not be able to pay its  debts as they  become  due in the usual  course of
business or (ii) the  corporation's  total  assets would be less than the sum of
its total  liabilities  plus  (unless  otherwise  provided  in its  articles  of
incorporation)  the amount  that  would be needed  upon the  dissolution  of the
corporation to satisfy the preferential  rights, if any, of shareholders  having
superior preferential rights to the shareholders receiving the distribution. The
Pennsylvania   Bylaws  do  not  limit  the  power  to  make   distributions   to
shareholders.

        Under Delaware law,  directors may,  subject to any  restrictions in the
corporation's certificate of incorporation, declare and pay dividends either (i)
out of its surplus or (ii) in case there is no  surplus,  out of the net profits
for the fiscal  year in which the  dividend  is  declared  and/or the  preceding
fiscal year. The directors of a Delaware  corporation may not declare a dividend
out of net profits,  however, if the capital of the corporation is less than the
aggregate amount of capital  represented by the issued and outstanding  stock of
all classes having a preference upon the  distribution  of assets.  The Delaware
Certificate does not restrict the payment of dividends.

                                       17


Fiduciary Duty of Directors

        Both  Pennsylvania  and Delaware law provide that the Board of Directors
has the  ultimate  responsibility  for  managing  the  business and affairs of a
corporation.  In  discharging  this  function,  directors  of  Pennsylvania  and
Delaware   corporations  owe  fiduciary  duties  of  care  and  loyalty  to  the
corporations   for  which  they  serve  as  directors.   Directors  of  Delaware
corporations  also owe fiduciary duties of care and loyalty to the corporation's
shareholders.

        Under   Pennsylvania   law,  a  director  of  a  Pennsylvania   business
corporation  stands in a  fiduciary  relationship  to the  corporation  and must
perform  his or her duties as a director  in good  faith,  in a manner he or she
reasonably believes to be in the best interests of the corporation and with such
care, including reasonable inquiry, skill and diligence, as a person of ordinary
prudence would use under similar circumstances.  In performing these duties, the
director is entitled to rely, in good faith, on information,  opinions,  reports
or statements,  including financial statements and other financial data, in each
case  prepared by any of the  following:  (i) one or more  officers or employees
whom the  director  reasonably  believes to be  reliable  and  competent  in the
matters  presented;  (ii)  counsel,  public  accountants  or other persons as to
matters  which the director  reasonably  believes to be within the  professional
competence of these  persons;  and (iii) a committee of the Board upon which the
director does not serve,  duly  designated in accordance with law, as to matters
within  its  designated  authority,  which  committee  the  director  reasonably
believes to merit confidence.  A director will not be considered to be acting in
good faith if the director has knowledge  concerning the matter in question that
would cause his or her reliance to be unwarranted.

        Under  Delaware law,  Delaware  courts have held that the directors of a
Delaware  corporation are required to exercise an informed  business judgment in
the performance of their duties.  An informed  business  judgment means that the
directors  have  informed  themselves  of all  material  information  reasonably
available to them.  Delaware  courts have also imposed a heightened  standard of
conduct  upon  directors  in  matters  involving  a contest  for  control of the
corporation. A director of a Delaware corporation,  in the performance of his or
her duties,  is fully protected in relying,  in good faith,  upon the records of
the  corporation  and upon such  information,  opinions,  reports or  statements
presented to the corporation by any of the corporation's  officers or employees,
or  committees  of the Board,  or by any other person as to matters the director
reasonably  believes  are within  such  other  person's  professional  or expert
competence and who has been selected with reasonable care by or on behalf of the
corporation.

        The  Pennsylvania  BCL provides that, in discharging the duties of their
respective  positions,  the  Board of  Directors,  committees  of the  Board and
individual  directors may, in considering the best interests of the corporation,
consider  the  effects  of  any  action  upon  other  constituencies,  including
employees,  suppliers and customers of the  corporation and communities in which
offices or other  establishments  of the  corporation  are located and all other
pertinent  factors.  Absent a breach of a fiduciary  duty, lack of good faith or
self-dealing,  actions  taken  as a  director  are  presumed  to be in the  best
interests of the corporation. In contrast, the Delaware GCL does not contain any
statutory provision  permitting the Board of Directors,  committees of the Board
and  individual  directors,  when  discharging  the  duties of their  respective
positions,  to  consider  the  interests  of any  constituencies  other than the
corporation or its shareholders.

        It is unclear  under the current  state of  development  of Delaware law
whether and the extent to which the Board of Directors,  committees of the Board
and individual  directors may, in considering what is in the corporation's  best
interests or the effects of any action on the corporation, take into account the
interests of any  constituency  other than the  shareholders of the corporation.
Consequently,  the fiduciary duty provisions of the Pennsylvania BCL may provide
significantly  broader discretion,  and increased protection from liability,  to
directors in exercising their fiduciary duties, particularly in the context of a
threatened change in control.

Limitation of Director Liability

        Both the Delaware  Certificate  and the  Pennsylvania  Articles  contain
similar provisions that limit the monetary  liability of directors.  As a result
of the  provision  contained  in the  Pennsylvania  Articles,  as  permitted  by
Pennsylvania  law, a director  of Met-Pro  Pennsylvania  will not be  personally
liable for  monetary  damages for any action  taken,  or any failure to take any
action,  unless the director has breached or failed to perform the duties of his
or her office and the  breach or  failure to perform  constitutes  self-dealing,
willful  misconduct  or  recklessness.  Such  limitation  does not  apply to the
responsibility  or liability of a director  pursuant to any criminal  statute or
the liability of a director for the payment of taxes.

        Under  Delaware  law  and  the  provision  set  forth  in  the  Delaware
Certificate,  a  director  is  excused  from  monetary  liability  for breach of
fiduciary  duty as a director  unless the liability is for breach of the duty of
loyalty,  for acts or omissions  not in good faith or that  involve  intentional
misconduct or a knowing  violation of law, for a willful or negligent payment of
an unlawful  dividend  or unlawful  stock  purchase  or  redemption,  or for any
transaction from which the director derived an improper personal benefit.

Indemnification of Officers and Directors

        Both Pennsylvania and Delaware law permit a corporation to indemnify its
directors and officers against  expenses,  judgments,  fines and amounts paid in
settlement   reasonably  incurred  by  them  in  connection  with  any  pending,
threatened  or completed  action or proceeding to which they were or are parties
or were  threatened  to be made  parties  by reason of the fact that they are or
were  directors  or officers of the  corporation.  Both states' laws also permit
indemnification  against  expenses  reasonably  incurred in connection  with any
pending,  threatened or completed  derivative action, if the director or officer
has acted in good faith and in a manner the director  reasonably  believed to be
in or not opposed to the best interests of the corporation  and, with respect to
any criminal  proceeding,  had no reasonable cause to believe his or her conduct
was unlawful. Under  both states' laws, court  approval is required with respect

                                       18


to any payment made with respect to a derivative action.  Furthermore,  both the
Pennsylvania  BCL and  the  Delaware  GCL  provide  that  expenses  incurred  in
defending any action or proceeding may be paid by the  corporation in advance of
the final  disposition  upon  receipt of an  undertaking  by or on behalf of the
director or officer to repay the amount if it is ultimately  determined that the
director or officer is not entitled to be indemnified by the corporation.

        In  both  Pennsylvania  and  Delaware,   the  statutory  provisions  for
indemnification  and  advancement  of expenses  are  non-exclusive  of any other
rights,  such as rights under  contract,  a bylaw or by vote of  shareholders or
disinterested   directors,   to  which  a  person  seeking   indemnification  or
advancement of expenses may be entitled.  Both the Delaware  Certificate and the
Pennsylvania  Articles require  indemnification of directors and officers to the
fullest extent  permitted by the laws of the respective  state.  With respect to
the   Pennsylvania   Articles,   these  boundaries  would  be  dictated  by  the
Pennsylvania  BCL, which provides for  indemnification  of a director or officer
unless the  conduct of the  director  or  officer  is  determined  by a court to
constitute willful misconduct or recklessness. The Delaware GCL does not contain
such an express  restriction on  indemnification,  although the Delaware  courts
have held that  indemnification  cannot be given with  respect  to  willful  and
intentional misconduct.

        The directors and officers of Met-Pro  Pennsylvania would be entitled to
the benefits of the  indemnification  provisions  set forth in the  Pennsylvania
Articles. Because these persons have a financial interest in these arrangements,
the adoption of these provisions could be deemed an interested transaction under
the  Pennsylvania   BCL.  The  Pennsylvania  BCL  provides  that  an  interested
transaction  will  not be void  or  voidable  if the  material  facts  as to the
interest and the  transaction  are  disclosed  or are known to the  shareholders
entitled to vote thereon,  and the transaction is specifically  approved in good
faith  by vote of the  shareholders.  The  text  of the  Pennsylvania  Articles,
providing for  indemnification  of its  directors and officers,  is set forth in
Appendix C. The  adoption of the  Pennsylvania  Articles  will not be subject to
challenge as an interested  transaction if shareholder approval of the merger is
obtained.  In addition,  shareholder  approval will deny a shareholder  or third
party the right to challenge the validity or  enforceability of these provisions
on other grounds.  The indemnification  provisions of the Pennsylvania  Articles
have  not  been  adopted  in  response  to any  recent,  pending  or  threatened
litigation.

Derivative Suits

        Under  Pennsylvania  law, a shareholder  may maintain a derivative  suit
even  if the  shareholder  was not a  shareholder  at the  time  of the  alleged
wrongdoing if a court  determines that a preliminary  showing has been made that
there is a strong  prima  facie  case in favor  of the  claim  and that  serious
injustice  would result  without such suit.  In contrast,  Delaware law provides
that a  shareholder  may  bring  a  derivative  suit  only  if he or  she  was a
shareholder  at the  time  of the  alleged  wrongdoing  or  obtained  the  stock
thereafter by operation of law.

Rights Plan and Anti-takeover Laws

        Pennsylvania  statutory law  explicitly  approves  shareholders'  rights
plans (also known as "poison pills") such as the Company's  Stockholders' Rights
Plan adopted in January 2000 (the "Rights Plan"), but specific rights plans will
probably  still be subject to evaluation on a case-by-case  basis.  In Delaware,
stockholders'  rights plans have been  sanctioned  by court  decisions.  In that
regard,  differences between Delaware and Pennsylvania's court systems and legal
precedents may affect the outcome of any legal challenge to the Rights Plan. The
Rights Plan was written to meet the standards  established  in Delaware law, and
if the  merger is  approved,  the  Company  may  revise  its  Rights  Plan if it
determines that Pennsylvania standards are materially different than Delaware's.
Although the reincorporation is not proposed as a means by which to increase the
anti-takeover defenses available to the Company, the Company's ability to defend
against an unwanted takeover of the Company are likely to be strengthened by the
reincorporation.  The  reincorporation  is not proposed in  connection  with any
specific  event or  expression  of interest in or threat to seek  control of the
Company.

        Both  Delaware and  Pennsylvania  have adopted a "business  combination"
type of takeover statute.  Business  combination  statutes  generally prohibit a
target  corporation  from  engaging  in  any  "business   combination"  with  an
"interested  stockholder"  of the  target  corporation  for a set period of time
following  the  date  on  which  the  interested  stockholder  became  such.  An
interested stockholder is typically defined as the direct or indirect beneficial
owner of a specified percentage of the target corporation's outstanding shares.

        Section 203 of the Delaware GCL provides  that a person who acquires 15%
or more of the  outstanding  voting stock of a Delaware  corporation  becomes an
"interested stockholder",  and the corporation may not effect mergers or certain
other "business  combinations"  with the interested  stockholder for a period of
three  years,  unless (i) prior to such date,  the Board of  Directors  approved
either  the  business  combination  or  the  transaction  that  resulted  in the
stockholder's  becoming  an  interested  stockholder;  or (ii) upon  becoming an
interested  stockholder,  the stockholder  then owned at least 85% of the voting
stock, as defined in Section 203; or (iii) subsequent to such date, the business
combination  is approved by both the Board of Directors  and by at least 66-2/3%
of the  corporation's  outstanding  voting stock,  excluding shares owned by the
interested  shareholder.  For these  purposes,  the term "business  combination"
includes mergers,  asset sales and other similar transactions with an interested
stockholder.  An  "interested  stockholder"  is  a  person  who,  together  with
affiliates and associates,  owns (or, within the prior three years, did own) 15%
or more of the corporation's voting stock.

        Pennsylvania  law provides a registered  corporation  the option,  under
certain  circumstances,  to avail  itself  of  certain  statutory  anti-takeover
measures  set  forth in the  Pennsylvania  BCL.  In  general  but  with  certain
exceptions,  a registered  corporation must "opt out" of these provisions by way
of a provision  in its articles of  incorporation,  or by way of an amendment to
its articles of incorporation  approved by the shareholders.  The following is a
list of the principal optional anti-takeover provisions that are provided in the
Pennsylvania BCL for Pennsylvania registered corporations:

                                       19



        - Section  1715,  which  expressly  states  that the  fiduciary  duty of
        directors  does not  require  them to redeem any rights  under or render
        inapplicable any shareholder rights plan or certain of the anti-takeover
        provisions of the Pennsylvania BCL;

        - Section 2538,  which relates to shareholder  approval of  transactions
        between a corporation and an "interested shareholder";

        - Subchapter  25E,  which,   with  certain   exceptions,   entitles  the
        shareholders  to be paid the fair  value of their  shares by anyone  who
        acquires 20% or more of the outstanding voting power of the corporation;

        - Subchapter  25F,  which imposes  certain  financial  requirements  and
        restrictions on business combinations with interested shareholders;

        - Subchapter  25G,  which,  with certain  exceptions,  limits the voting
        rights  of  persons  who have  acquired  20% or more of the  outstanding
        voting power of the corporation;

        - Subchapter 25H, which requires disgorgement of certain profits made by
        controlling shareholders following their attempts to gain control of the
        corporation;

        - Subchapter  25I,  relating to  severance  compensation  for  employees
        terminated following certain control-share acquisitions; and

        - Subchapter 25J, relating generally to labor contracts.

        The Pennsylvania BCL and the  Pennsylvania  Articles contain  provisions
pursuant  to which  Met-Pro  Pennsylvania  has elected not to be governed by the
provisions  of Section  2538 or  Subchapters  25E,  25G, 25I and 25J of the BCL.
Following the merger, the provisions of Section 1715 and Subchapters 25F and 25H
of the BCL will apply to the Company.  These  provisions  are  described in more
detail below.

Section 1715

        Section 1715 of the Pennsylvania BCL permits the board of directors,  in
considering  the best  interests of the  corporation,  to consider to the extent
they deem  appropriate the effects of any action upon any or all groups affected
by such action,  including  shareholders,  employees,  suppliers,  customers and
creditors of the  corporation,  and upon  communities  in which offices or other
establishments  of the corporation are located.  Section 1715 of  Pennsylvania's
BCL authorizes the directors to consider the short-term and long-term  interests
of the corporation and the potential benefit of these interests to the continued
independence  of the  corporation.  In taking  action,  the  directors  may also
consider the resources,  intent and conduct (past,  stated and potential) of any
person  seeking  to  acquire  control of the  corporation.  Section  1715 of the
Pennsylvania  BCL  further  provides  that the board of  directors  shall not be
required, in considering the best interests of the corporation or the effects of
any action, to regard any corporate  interest or the interests of any particular
group affected by such action as a dominant or controlling interest or factor.

        Under  Section  1715,  directors  are not  required to redeem any rights
under a  shareholder  rights plan or to act as the board  solely  because of the
effect such action might have on a potential or proposed  acquisition of control
of a  corporation.  Directors are not required to act under  Pennsylvania's  BCL
solely  because  of  the  consideration   that  might  be  offered  or  paid  to
shareholders in such an acquisition.

        Section 1715 codifies the presumption that is reflected in the "business
judgment rule" that absent breach of fiduciary  duty, lack of good faith or self
dealing,  any act as the  Board of  Directors,  a  committee  or any  individual
director  shall be presumed to be in the best interests of the  corporation.  In
assessing  whether a director  has  discharged  his duties  with the  applicable
standard of care, the  Pennsylvania BCL protects the actions of a majority board
of disinterested  directors in resisting  unsolicited takeovers by retaining the
ordinary  business  judgment  rule with  respect to the  adoption  of  defensive
measures.

Subchapter 25F--Shareholder Approval of Certain Business Combinations

        The  Pennsylvania  BCL  contains  certain  provisions  designed  to make
certain  kinds  of  "unfriendly"  corporate  takeovers,  or  other  transactions
involving a corporation  and one or more of its significant  stockholders,  more
difficult. Under Subchapter F of Chapter 25 of the Pennsylvania BCL ("Subchapter
25F"),  certain  "business  combinations"  by  Pennsylvania   corporations  with
"interested shareholders" are subject to a five-year moratorium unless specified
conditions are met. Section 203 of the Delaware GCL provides a similar provision
to Subchapter 25F. The  Pennsylvania  Articles do not opt out of Subchapter 25F,
and accordingly, following the effective date of the merger, Subchapter 25F will
apply to the Company.

        Subchapter 25F prohibits a Pennsylvania  corporation  from engaging in a
"business combination" with an "interested shareholder" for five years following
the date that such  person  becomes  an  interested  shareholder.  With  certain
exceptions, an interested shareholder is a person or group who or which owns 20%
or more of the corporation's  outstanding  voting stock (including any rights to
acquire  stock  pursuant  to  an  option,  warrant,  agreement,  arrangement  or
understanding,  or upon the exercise of conversion or exchange rights, and stock
with respect to which the person has voting rights only),  or is an affiliate or
associate  of the  corporation  and was the owner of 20% or more of such  voting
stock at any time within the previous five years.

                                       20


        For purposes of  Subchapter  25F,  the term  "business  combination"  is
defined broadly to include mergers with or caused by the interested shareholder;
sales or other  dispositions  to the  interested  shareholder  of  assets of the
corporation or a subsidiary  equal to 10% or more of the aggregate  market value
of  the   corporation's   consolidated   assets  or  its  outstanding  stock  or
representing  10% or more of its earning  power or net income;  the  issuance or
transfer by the  corporation or a subsidiary of stock of the corporation or such
subsidiary to the  interested  shareholder  equal to 5% or more of the aggregate
market value of the  corporation's  outstanding stock (except for transfers in a
conversion or exchange or a pro rata distribution or certain other transactions,
none of which increase the interested  shareholder's  proportionate ownership of
any  class or series  of the  corporation's  or such  subsidiary's  stock);  the
adoption  of any plan for the  liquidation  or  dissolution  of the  corporation
proposed by or with the  interested  shareholder;  or receipt by the  interested
shareholder (except  proportionately as a shareholder),  directly or indirectly,
of any loans, advances, guarantees, pledges or other financial benefits provided
by or through the corporation or a subsidiary.

        The five-year moratorium imposed on business  combinations by Subchapter
25F does not apply if: (i) prior to the date on which a  shareholder  becomes an
interested  shareholder  the Board of  Directors  approves  either the  business
combination  or  the  transaction  that  resulted  in  the  person  becoming  an
interested shareholder; (ii) the business combination is approved by the holders
of a majority of the outstanding  voting stock (excluding the voting stock owned
by the  interested  shareholder)  and at the time of such  vote  the  interested
shareholder  owns 80% of the  corporation's  voting stock; or (iii) the business
combination  is  approved by (A) the  holders of all of the  outstanding  voting
stock  or (B)  the  holders  of a  majority  of  the  outstanding  voting  stock
(excluding the voting stock owned by the interested shareholder) no earlier than
five years after the date such person became an interested shareholder.

        A  Pennsylvania  corporation  may elect not to be governed by Subchapter
25F by a provision in its original  articles of incorporation or an amendment to
the articles or the Pennsylvania  corporation's  bylaws, which amendment must be
approved by a majority of the  outstanding  voting  stock and may not be further
amended by at least 85% of the members of the Board of Directors.

Subchapter 25H--Anti-Greenmail Provisions

        Subchapter H of Chapter 25 of the Pennsylvania  BCL  ("Subchapter  25H")
applies in the event that (i) any person or group  publicly  discloses  that the
person or group may acquire control of the corporation or (ii) a person or group
acquires  (or  publicly  discloses an offer or intent to acquire) 20% or more of
the voting power of the corporation  and, in either case, sells shares within 18
months  thereafter.   Any  profits  from  sales  of  equity  securities  of  the
corporation  by the person or group  during such 18 month  period  belong to the
corporation if the securities  that were sold were acquired  during the 18 month
period or within 24 months prior thereto.  The Pennsylvania  Articles do not opt
out of Subchapter  25H, and  accordingly,  following  the effective  date of the
merger, Subchapter 25H will apply to the Company.

        The purpose of Subchapter 25H is to deter so-called "raiders" who do not
genuinely seek control of the  corporation  but merely wish to put it "in play,"
which is typically followed by an increase in the market price, so that they can
then either exact  "greenmail" from the corporation by selling their stock to it
or sell their stock in the open market, in either case at a substantial premium.

        There are two  separate  sets of  circumstances  that may  result in the
characterization  of  someone  as  a  "controlling   person"  (or  group)  under
Subchapter 25H. The first is the actual acquisition of, the offer to acquire, or
the public disclosure of an interest to acquire,  20 percent of the voting power
of the corporation.  The second is any public  disclosure that a person may seek
to acquire control of the corporation.

        There  is a  specific  safe  harbor  provision  to the  effect  that the
disgorgement provisions will not apply to proxy contests so long as they are not
used  to put  the  corporation  in play or in an  attempt  to  acquire  control.
Subchapter  25H does not apply to  traditional  proxy  contests,  including  the
routine election of directors or corporate governance matters.

        Certain  transfers  (either the  acquisition or  disposition)  of equity
securities  are  exempt  from  the  disgorgement  provisions.  The  disgorgement
provisions  do not apply to  certain  specifically  identified  acquisitions  or
dispositions  of stock so long as they have been  approved by the  directors and
ratified  by  shareholders.  The  dispositions  must  also  have  been made by a
controlling  person or group that is "in control of the  corporation".  Only the
corporation or any shareholder in a derivative action may enforce the obligation
to disgorge the profits realized by the controlling person.

Federal Income Tax Consequences of the Reincorporation

        The reincorporation  provided for in the merger agreement is intended to
be a  tax-free  reorganization  under  the  Internal  Revenue  Code of 1986,  as
amended. Provided the reincorporation qualifies as a reorganization,  no gain or
loss will be  recognized  to the  holders of capital  stock of the  Company as a
result  of  consummation  of the  reincorporation,  and no gain or loss  will be
recognized by Met-Pro  Delaware or Met-Pro  Pennsylvania.  Each former holder of
capital  stock of the Company  will have the same basis in the capital  stock of
Met-Pro Pennsylvania  received by such holder pursuant to the reincorporation as
such holder has in the capital  stock of the Company  held by such holder at the
time of consummation of the reincorporation.  Each shareholder's  holding period
with  respect to Met-Pro  Pennsylvania's  capital  stock will include the period
during which such holder held the corresponding  Company capital stock, provided
the  latter  was  held  by  such  holder  as a  capital  asset  at the  time  of
consummation of the reincorporation.

        The Board of Directors recommends that you specifically  indicate on the
proxy  card  your vote in favor of this  proposal.  Otherwise,  if your  Met-Pro
shares  are  registered  in the name of your  broker,  your  broker  will not be
permitted  to vote in favor of this  proposal  in the  absence of your  specific
direction  on the proxy  card,  the  effect of which  will be the same as a vote
against this proposal.

determined by the Board of Directors of the Surviving  Corporation in compliance
with  applicable  laws, or other such  additional  legends as agreed upon by the
holder and the Surviving Corporation.

Stock  is to be  issued  in a name  other  than  that in which  the  certificate
surrendered  in exchange  therefor  is  registered,  it shall be a condition  of
issuance thereof that the certificate so surrendered  shall be properly endorsed
and  otherwise  in proper form for  transfer,  that such  transfer  otherwise be

least 80% of the  outstanding  shares entitled to vote at any regular or special
meeting duly convened after written notice to the shareholders that the purpose,
or one of the purposes, of the meeting is to consider the amendment or repeal of
the Bylaws.

         ARTICLE 8:

                (a) From and after the effective  date of the merger between the
Company  and  Met-Pro  Corporation,  a  Delaware  corporation,  pursuant  to  an
Agreement  and  Plan of  Merger  dated  as of the  date  of  these  Articles  of
Incorporation  between the Company  and Met-Pro  Corporation,  no action that is

                (b)  Special  meetings  of  shareholders  of the  Company may be

state of incorporation of the Company, (b) a disposition of all or substantially
all  of  the  assets  of the  Company,  or (c)  any  purchase,  lease  or  other
acquisition  by  the  Company  or  any of its  subsidiaries  of  any  assets  or
securities of any other corporation, person or entity in exchange for securities
of the Company or any of its subsidiaries. Notwithstanding the foregoing, (1) if
a majority of the Board of Directors  approves any of the transactions set forth
in clauses (a) or (b) of this Article 10, then the affirmative vote of more than
50% of the  outstanding  shares  entitled to vote at a duly convened  regular or
special  meeting  of the  shareholders  shall  be  sufficient  to  approve  such
transaction;  and  (2) if a  majority  of the  Board  of  Directors  approves  a
transaction  set forth in clause  (c) of this  Article  10,  then no vote of the
outstanding  shares  shall be necessary  to approve  such  transaction  unless a

                                       29


        ARTICLE 11:

                (a) (1) A director  of the  Company  shall  stand in a fiduciary
relation  to the  Company  and shall  perform  his or her duties as a  director,
including  the  director's  duties as a member of any  committee of the Board of
Directors  upon which the  director  may serve,  in good faith,  in a manner the
director  reasonably  believes to be in the best  interests of the Company,  and
with such care, including reasonable inquiry,  skill and diligence,  as a person
of ordinary prudence would use under similar circumstances. In performing his or
her duties,  a director shall be entitled to rely in good faith on  information,
opinions,  reports  or  statements,  including  financial  statements  and other
financial data, in each case prepared or presented by any of the following:  (i)
one or more  officers or employees  of the Company whom the director  reasonably
believes to be reliable  and  competent  in the  matters  presented;  (ii) legal
counsel,  public  accountants  or other persons as to matters which the director
reasonably  believes to be within the professional or expert  competence of such
persons;  or (iii) a committee of the Board of Directors upon which the director
does not serve, duly designated in accordance with law, as to matters within its
designated authority,  which committee the director reasonably believes to merit
confidence. A director shall not be considered to be acting in good faith if the
director has  knowledge  concerning  the matter in question that would cause the
director's reliance to be unwarranted.

                    (2) In discharging the duties of their respective positions,
the Board of  Directors,  committees  of the Board of Directors  and  individual
directors  may, in considering  the best interests of the Company,  consider the
effects of any action upon employees, suppliers and customers of the Company and
communities in which offices or other establishments of the Company are located,
and all other pertinent  factors.  The  consideration of these factors shall not
constitute a violation of Article 11(a)(1) hereof.

                    (3) Absent breach of fiduciary  duty,  lack of good faith or
self-dealing,  actions  taken as a  director  or any  failure to take any action
shall be presumed to be in the best interests of the Company.

                    (4) A  director  of the  Company  shall  not  be  personally
liable,  as such, for monetary  damages for any action taken,  or any failure to
take any action,  unless: (i) the director has breached or failed to perform the
duties of his or her office under  Article  11(a)(1)  through  Article  11(a)(3)
hereof;  and (ii) the breach or failure  to  perform  constitutes  self-dealing,
willful misconduct or recklessness.

                    (5) The  provisions  of Article  11(a)(4)  hereof  shall not
apply to: (i) the  responsibility  or  liability  of a director  pursuant to any
criminal  statute;  or (ii) the liability of a director for the payment of taxes
pursuant to local, state or federal law.

                (b) Neither any amendment nor repeal of this Article 11, nor the
adoption of any provision of these Articles of Incorporation  inconsistent  with
this  Article 11,  shall  eliminate  or reduce the effect of this  Article 11 in
respect of any matter occurring, or any action or proceeding accruing or arising
or  that,  but for  this  Article  11,  would  accrue  or  arise,  prior to such
amendment, repeal or adoption of an inconsistent provision.

        ARTICLE 12:

                (a) Every  person  who is or was a  director  or  officer of the
Company shall be indemnified by the Company to the fullest extent allowed by the
BCL against all liabilities and expenses imposed upon or incurred by that person
in  connection  with  any  proceeding  in which  that  person  may be  made,  or
threatened to be made, a party,  or in which that person may become  involved by
reason of that  person  being or having been a director or officer of or serving
or having served in any capacity with any other enterprise at the request of the
Company,  whether or not that  person is a director or officer or  continues  to
serve the other  enterprise at the time the  liabilities or expenses are imposed
or incurred.

                (b) To the fullest  extent  permitted  by  applicable  law,  the
Company is authorized to provide indemnification of (and advancement of expenses
to)  agents of the  Company  (and any other  persons to which  Pennsylvania  law
permits  the  Company to provide  indemnification)  through  By-law  provisions,
agreements  with  such  agents  or  other  persons,  votes  of  shareholders  or
disinterested  directors  or  otherwise,  in excess of the  indemnification  and
advancement  otherwise  permitted by the BCL subject  only to limits  created by
applicable  Pennsylvania  law  (statutory  or  non-statutory),  with  respect to
actions for breach of duty to the Company, its shareholders and others.

                (c) Neither any amendment nor repeal of this Article 12, nor the
adoption of any provision of these Articles of Incorporation  inconsistent  with
this  Article 12,  shall  eliminate  or reduce the effect of this  Article 12 in
respect of any matter occurring, or any action or proceeding accruing or arising
or  that,  but for  this  Article  12,  would  accrue  or  arise,  prior to such
amendment, repeal or adoption of an inconsistent provision.

        ARTICLE 13: These Articles of  Incorporation  may be amended at any time
as  permitted  by law,  subject  to the  express  terms  hereof,  and all rights
conferred  upon the  shareholders  or others herein are granted  subject to this
reservation.  Any amendment that (a) changes the shareholder vote percentage for
approval of an item specified by these Articles of  Incorporation or (b) changes
the  provisions  of Article 6,  Article 7, Article 8, Article 9, or this Article
13,  must be  first  approved  by an  affirmative  vote of at  least  80% of the
outstanding  shares  entitled  to vote at a duly  convened  regular  or  special
meeting of the shareholders. Notwithstanding the foregoing, if a majority of the
Board of Directors  approves an amendment that (a) changes the shareholder  vote
percentage for approval of an item specified by these Articles of  Incorporation
or (b) changes the  provisions of Article 6, Article 7, Article 8, Article 9, or
this Article 13, then the  affirmative  vote of more than 50% of the outstanding
shares  entitled to vote at a duly  convened  regular or special  meeting of the
shareholders shall be sufficient to approve such amendment.

                                       30

with such  provisions  shall not be  considered or acted upon at such meeting of
shareholders.

                (2)  A  proposal  by  a  shareholder  for  the  nomination  of a
candidate  for  election  by  shareholders  as a  director  at  any  meeting  of

                (3) In the case of an annual  meeting,  to be  timely,  any such
written  proposal of nomination  must be delivered to or mailed and received at,
the principal  executive  offices of the  Corporation  not less than 90 days nor

postponements,  deferrals  or  adjournments  of that  meeting  to a later  date;
provided,  however, that if less than 70 days' notice or prior public disclosure
of the date of the scheduled  meeting is given or made, such written proposal of
nomination  to be timely must be so  delivered  or  received  not later than the
close of business on the tenth  (10th) day  following  the earlier of the day on
which such notice of the date of the scheduled  meeting was mailed or the day on
which such public disclosure was made.

                (4) In the case of a special meeting of  shareholders,  any such
written  proposal of  nomination  must be received by the Board of Directors not
less than five business days after the earlier of the date the Corporation shall
have mailed notice to its  shareholders  that a special  meeting of shareholders
will be  held,  issued  a  press  release,  filed a  periodic  report  with  the
Securities and Exchange  Commission or otherwise  publicly  disseminated  notice
that a special meeting of shareholders will be held.

                                       32


                (5) Such written proposal of nomination shall set forth: (A) the

person so proposed to serve as a director if nominated and elected as a director
and (G) such other  information  regarding each such person as would be required
under the proxy solicitation rules of the Securities and Exchange  Commission if

proposed.

                (6) If a written  proposal of nomination  submitted to the Board
of Directors fails, in the reasonable  judgment of the presiding  officer of the
meeting or the Board of Directors or a nominating  committee  established by it,
to contain the information  specified in clause (5) of this Section 2.3(a) or is
otherwise  deficient,  the  presiding  officer  of the  meeting  or the Board of
Directors or the nominating committee shall, as promptly as is practicable under
the  circumstances,  provide  written notice to the  shareholder(s)  making such
nomination of such failure or  deficiency in the written  proposal of nomination
and such  nominating  shareholder  shall have five business days from receipt of
such notice to submit a revised  written  proposal of  nomination  that corrects
such failure or deficiency in all material respects.

                (7)  Compliance  by a  shareholder  with the  provisions of this
Section  2.3(a)  shall not be deemed to require  the  acceptance  of the written
proposal or nomination.

        (b) The  provisions  of this Section  2.3(b) shall apply to  shareholder
proposals  relating  to matters  other than  nominations  for and  elections  of
directors:

                (1) At a meeting of  shareholders,  only such business  shall be
conducted,  and only such  proposals  shall be acted  upon,  as shall  have been
brought  before the such  meeting (i) by, or at the  direction  of, the Board of
Directors or (ii) by any shareholder of the Corporation who complies with all of
the  procedures  set  forth in this  Section  (a  "Shareholder  Matter").  For a
proposal  to  be  properly  brought  before  a  meeting  by a  shareholder,  the
shareholder must have given timely notice in writing,  delivered in person or by
first  class  United  States  mail  postage  prepaid or by  reputable  overnight
delivery service,  charges prepaid, to the Board of Directors of the Corporation
in care of the  Secretary  of the  Corporation  at the  principal  office of the
Corporation, within the time limits specified in this Section 2.3(b).

                (2)  In  the  case  of  an  annual  meeting,  to  be  timely,  a
shareholder's  notice  must be  delivered  to or mailed  and  received  at,  the
principal  executive  offices of the  Corporation not less than 90 days nor more
than  120  calendar  days  prior to the  scheduled  meeting,  regardless  of any
postponements,  deferrals  or  adjournments  of that  meeting  to a later  date;
provided,  however, that if less than 70 days' notice or prior public disclosure
of the date of the scheduled meeting is given or made, notice by the shareholder
to be timely  must be so  delivered  or  received  not  later  than the close of
business on the tenth (10th) day  following the earlier of the day on which such
notice of the date of the scheduled  meeting was mailed or the day on which such
public  disclosure was made. In the case of a special  meeting of  shareholders,
any such written  notice of a proposal of a Shareholder  Matter must be received
by the Board of Directors  not less than five business days after the earlier of
the date the  Corporation  shall have mailed notice to its  shareholders  that a
special meeting of shareholders  will be held,  issued a press release,  filed a
periodic  report  with the  Securities  and  Exchange  Commission  or  otherwise
publicly  disseminated  notice that a special  meeting of  shareholders  will be
held.

                (3) A  shareholder's  notice to the Secretary shall set forth as
to each  matter  the  shareholder  proposes  to  bring  before  the  meeting  of
shareholders  information  regarding such Shareholder  Matter  equivalent to the
information  regarding such Shareholder  Matter that would be required under the
proxy  solicitation  rules of the Securities and Exchange  Commission if proxies
were solicited for shareholder consideration,  including (a) a brief description
of the  proposal  desired to be brought  before the  meeting and the reasons for
conducting  such  business at the meeting,  (ii) the name and  address,  as they
appear on the  Corporation's  books, of the shareholder  proposing such business
and any other  shareholders  known by such  shareholder  to be  supporting  such
proposal,  (b) the class and number of shares of the  Corporation's  stock which
are beneficially owned by the shareholder on the date of such shareholder notice
and by any other  shareholders  known by such  shareholder to be supporting such
proposal on the date of such shareholder  notice, and (c) any financial interest
of the shareholder in such proposal.

                (4) If a written  notice of a proposal of a  Shareholder  Matter
submitted to the Board of Directors  fails,  in the  reasonable  judgment of the
presiding  officer of the  meeting  or the Board of  Directors,  to contain  the
information specified in clause (3) hereof or is otherwise deficient,  the Board
of  Directors  shall,  as promptly as is  practicable  under the  circumstances,
provide  written notice to the  shareholder  who submitted the written notice of
presentation  of a  Shareholder  Matter of such  failure  or  deficiency  in the
written  notice of  presentation  of a Shareholder  Matter and such  shareholder
shall have five  business  days from  receipt of such notice to submit a revised
written  notice of  presentation  of a matter  that  corrects  such  failure  or
deficiency in all material respects.

                (5)  Compliance  by a  shareholder  with the  provisions of this
Section 2.3(b) shall not be deemed to require the acceptance of the  Shareholder
Matter.

        SECTION 2.4 Special  meetings of the  shareholders  may be called at any
time by the Board of  Directors  or the  Chairman of the Board,  who may fix the
date,  time and place of the meeting.  If the Board of Directors or the Chairman
of the Board does not fix the date,  time or place of the  meeting,  it shall be
the duty of the Secretary to do so. A date fixed by the  Secretary  shall not be
more than 60 days after the date of the adoption of the  resolution of the Board
of Directors calling the special meeting.

        SECTION  2.5  Written  notice of each  meeting  other than an  adjourned
meeting  of  shareholders,  stating  the place and time,  and,  in the case of a
special  meeting of  shareholders,  the  general  nature of the  business  to be
transacted,  shall be provided to each shareholder of record entitled to vote at
the  meeting at such  address as appears on the books of the  Corporation.  Such
notice shall be given,  in accordance with the provisions of Article 30 of these
Bylaws, at least (a) ten days prior to the day named for a meeting to consider a
fundamental change under Chapter 19 of the Pennsylvania Business Corporation Law
of 1988 (the  "BCL") or (b) five days prior to the day named for the  meeting in
any other case.

        SECTION 2.6

        (a)  Whenever  the  Corporation  has been unable to  communicate  with a
shareholder for more than 24 consecutive  months because  communications  to the
shareholder are returned  unclaimed or the  shareholder has otherwise  failed to
provide the  Corporation  with a current  address,  the giving of notice to such
shareholder  pursuant to Section 2.5 of these Bylaws shall not be required.  Any
action or meeting that is taken or held without notice or  communication to that
shareholder  shall have the same validity as if the notice or communication  had
been duly given.  Whenever a shareholder provides the Corporation with a current
address,  this Section  2.6(a) shall cease to be applicable to such  shareholder
until such later time,  if any, as the terms of this Section  2.6(a) shall again
become applicable.

        (b)  The  Corporation  shall  not be  required  to  give  notice  to any
shareholder  pursuant to Section 2.5 hereof if and for as long as  communication
with such shareholder is unlawful.

        SECTION  2.7 The Board of  Directors  may  provide  by  resolution  with
respect to a specific meeting or with respect to a class of meetings that one or
more shareholders may participate in such meeting or meetings of shareholders by
means of conference  telephone or other electronic  technology by means of which
all  persons  participating  in the  meeting  can hear one  another,  including,
without  limitation,  the  Internet.  The presence or  participation,  including
voting and taking other action, at the meeting,  or the expression of consent or
dissent to corporate action, by a shareholder by such means, including,  without
limitation, the Internet, shall constitute presence of, or vote or action by, or
consent or dissent  of the  shareholder  at the  meeting.  Any notice  otherwise
required to be given in connection  with any meeting at which  participation  by
conference  telephone or other  communications  equipment is permitted  shall so
specify.

Bylaws,  shall  nevertheless  constitute a quorum for the purpose of acting upon
any  matter set forth in the notice of the  meeting  if the notice  states  that
those   shareholders  who  attend  the  adjourned  meeting  shall   nevertheless
constitute a quorum for the purpose of acting upon the matter.

                                     PROXIES

        SECTION  5.1  Every  shareholder  entitled  to  vote  at  a  meeting  of
shareholders may authorize another person or persons to act for such shareholder
by proxy.  Every proxy shall be executed or  authenticated by the shareholder or
his or her duly authorized attorney-in-fact and filed with or transmitted to the
Secretary of the  Corporation or its  designated  agent. A shareholder or his or
her duly  authorized  attorney-in-fact  may execute or authenticate a writing or
transmit  an  electronic  message  authorizing  another  person  to act for such
shareholder  by  proxy.  A proxy,  unless  coupled  with an  interest,  shall be
revocable at will,  notwithstanding  any other agreement or any provision in the
proxy to the  contrary,  but the  revocation  of a proxy shall not be  effective
until notice  thereof has been given to the Secretary of the  Corporation or its
designated  agent in writing or by electronic  transmission.  An unrevoked proxy
shall  not  be  valid  after  three  years  from  the  date  of  its  execution,
authentication  or  transmission  unless a  longer  time is  expressly  provided
therein.  A proxy shall not be revoked by the death or  incapacity of the maker,
unless before the vote is counted or the authority is exercised,  written notice
of such death or incapacity is given to the Secretary of the  Corporation or its
designated agent.

        SECTION 5.2 Where two or more proxies of a shareholder are present,  the
Corporation shall,  unless otherwise  expressly provided in the proxy, accept as
the vote of all shares represented  thereby the vote cast by a majority of them,
and, if a majority of the proxies  cannot agree  whether the shares  represented
shall be voted or upon the manner of voting the shares, the voting of the shares
shall be divided equally among those persons.

shareholders  entitled  to notice of, or to vote at, the  meeting,  which  time,
except in the case of an adjourned  meeting,  shall not be more than 60 days and
not less than 10 days  prior to the date of the  meeting of  shareholders.  Only
shareholders  of record on the date so fixed  shall be entitled to notice of, or
to vote at, such meeting, notwithstanding any transfer of shares on the books of
the Corporation after any record date fixed as aforesaid. The Board of Directors
may similarly fix a record date for the  determination of shareholders of record
for any other purpose,  such as the payment of a distribution or a conversion or
exchange of shares.

        SECTION 6.2 The Board of Directors may by  resolution  adopt a procedure
whereby  a  shareholder  of  the  Corporation  may  certify  in  writing  to the

name are held for the account of a specified person or persons.  Such resolution
may set forth: (a) the  classification  of shareholder who may certify;  (b) the
purpose or purposes  for which the  certification  may be made;  (c) the form of
certification and information to be contained therein;  (d) if the certification

provisions  with respect to the procedure as are deemed  necessary or desirable.
Upon receipt by the Corporation of a certification complying with the procedure,
the persons specified in the certification shall be deemed, for the purposes set
forth in the certification,  to be the holders of record of the number of shares
specified in place of the shareholder making the certification.

examine the list.

        SECTION 7.3 The original  transfer books for shares of the  Corporation,

        SECTION 8.1 Prior to any meeting of shareholders, the Board of Directors
may appoint judges of election, who may but need not be shareholders,  to act at
such  meeting  or any  adjournment  thereof.  If judges of  election  are not so
appointed,  the presiding officer of any such meeting may, and on the request of
any shareholder or his or her proxy shall, make such appointment at the meeting.
The number of judges shall be one or three.  No person who is a candidate for an
office to be filled at the meeting shall act as a judge of election.

        SECTION 8.2 In case any person appointed as a judge of election fails to
appear or fails or refuses  to act,  the  vacancy  so  created  may be filled by
appointment  made by the Board of Directors  in advance of the  convening of the
meeting or at the meeting by the presiding officer thereof.

        SECTION 8.3 The judges of election shall  determine the number of shares
outstanding and the voting power of each, the shares represented at the meeting,

all challenges and questions in any way arising in connection  with the right to
vote, count and tabulate all votes,  determine the result and do such other acts
as  may be  proper  to  conduct  the  election  or  vote  with  fairness  to all
shareholders.  The judges of election shall perform their duties impartially, in
good faith, to the best of their ability and as expeditiously as practicable. If
there are three  judges of  election,  the  decision,  act or  certificate  of a
majority shall be the decision, act or certificate of all.

        SECTION 8.4 On request of the presiding officer of the meeting or of any
shareholder,  the  judges of  election  shall  make a report in  writing  of any
challenge,  question or matter  determined by them and execute a certificate  of
any fact found by them.  Any report or  certificate  made by them shall be prima
facie evidence of the facts found by them.

classes,  if any,  entitled to elect directors  separately,  up to the number of
directors to be elected by the  shareholders,  or class or group of classes,  if
any,  shall be  elected.  The  directors  shall be divided  into three  classes,
designated  Class I, Class II and Class III,  and each class  shall be as nearly
equal in number as  possible.  Each class shall serve for a term of three years,
ending on the annual meeting of shareholders in 2004 (in the case of the Class I
directors),  in 2005 (in the case of the Class II directors) and in 2006 (in the
case of the Class III directors),  and for each three-year period thereafter. At
each annual meeting of shareholders,  that number of directors whose terms shall
then expire  shall be elected to serve for a term of three years and until their
successors  have been  elected or until  their  earlier  death,  resignation  or
removal.  A  decrease  in the number of  directors  shall not have the effect of
shortening the term of any incumbent director.

of ordinary prudence would use under similar circumstances. In performing his or
her duties,  a director shall be entitled to rely in good faith on  information,
opinions,  reports  or  statements,  including  financial  statements  and other
financial data, in each case prepared or presented by any of the following:  (a)
one  or  more  officers  or  employees  of the  Corporation  whom  the  director
reasonably  believes to be reliable and competent in the matters presented;  (b)
legal  counsel,  public  accountants  or other  persons as to matters  which the
director  reasonably believes to be within the professional or expert competence
of such  persons;  or (c) a committee of the Board of  Directors  upon which the
director does not serve,  duly  designated in accordance with law, as to matters
within  its  designated  authority,  which  committee  the  director  reasonably
believes to merit confidence. A director shall not be considered to be acting in
good faith if the director has knowledge  concerning the matter in question that
would cause the director's reliance to be unwarranted.

        SECTION 17.2 In discharging  the duties of their  respective  positions,
the Board of  Directors,  committees  of the Board of Directors  and  individual
directors may, in considering  the best interests of the  Corporation,  consider
the  effects  of any action  upon  employees,  suppliers  and  customers  of the
Corporation  and  communities  in which offices or other  establishments  of the
Corporation are located,  and all other pertinent factors.  The consideration of
these factors shall not constitute a violation of Section 17.1 hereof.

        SECTION  17.3 Absent  breach of  fiduciary  duty,  lack of good faith or
self-dealing,  actions  taken as a  director  or any  failure to take any action
shall be presumed to be in the best interests of the Corporation.

        SECTION  17.4 A  director  of the  Corporation  shall not be  personally
liable,  as such, for monetary  damages for any action taken,  or any failure to
take any action,  unless: (a) the director has breached or failed to perform the
duties of his or her office under Sections 17.1 through 17.3 hereof; and (b) the
breach or failure to perform  constitutes  self-dealing,  willful  misconduct or
recklessness.

        SECTION 17.5 The  provisions  of Section 17.4 hereof shall not apply to:
(a) the  responsibility  or  liability  of a director  pursuant to any  criminal
statute; or (b) the liability of a director for the payment of taxes pursuant to
local, state or federal law.

                                    OFFICERS

        SECTION  18.1 The  Corporation  shall  have a Chairman  of the Board,  a
President,  a  Secretary  and a  Treasurer,  or  persons  who shall act as such,
regardless  of the name or title by which  they may be  designated,  elected  or
appointed and may have such other  officers and assistant  officers as the Board
of  Directors  may  authorize  from time to time.  The  Chairman  of the  Board,
President and Secretary  shall be natural persons of full age. The Treasurer may
be a corporation,  but if a natural person shall be of full age. It shall not be
necessary  for any  officer,  other  than the  Chairman  of the  Board,  to be a
director.  Any number of offices may be held by the same  person.  Each  officer
shall hold office at the pleasure of the Board of Directors and until his or her
successor  has been elected or until his or her earlier  death,  resignation  or
removal.  Any  officer  may  resign  at any  time  upon  written  notice  to the
Corporation.  The  resignation  shall be effective  upon receipt  thereof by the
Corporation  or at such  subsequent  time as may be  specified  in the notice of
resignation.  The  Corporation  may  secure  the  fidelity  of any or all of the
officers by bond or otherwise.

        SECTION   18.2  Except  as   otherwise   provided  in  the  Articles  of
Incorporation,  an officer shall perform his or her duties as an officer in good
faith, in a manner the officer  reasonably  believes to be in the best interests
of the Corporation and with such care, including  reasonable inquiry,  skill and
diligence,   as  a  person  of  ordinary   prudence   would  use  under  similar
circumstances. A person who so performs his or her duties shall not be liable by
reason of having been an officer of the Corporation.

        SECTION 18.3 Any officer or agent of the  Corporation  may be removed by
the Board of  Directors  with or without  cause.  The  removal  shall be without
prejudice to the contract rights, if any, of any person so removed.  Election or
appointment of an officer or agent shall not of itself create  contract  rights.
If the office of any officer  becomes vacant for any reason,  the vacancy may be
filled by the Board of Directors.

shareholders  and the Board of Directors and shall have  responsibility  for the

Unless  otherwise  directed  by the Board of  Directors  from time to time,  the
Chairman  shall  have the  power  to vote and  otherwise  act on  behalf  of the
Corporation,  in person or by proxy,  at any meeting of  shareholders of or with
respect  to any action of  shareholders  of any other  corporation  in which the
Corporation may hold securities and otherwise to exercise any and all rights and
powers  which  the  Corporation  may  possess  by  reason  of its  ownership  of
securities in such other corporation.

Board or the Board of  Directors.  The  President  shall  perform the duties and
exercise the powers of the Chairman of the Board in the absence or disability of
the Chairman.

        SECTION  21.1  The  Vice  President  or,  if more  than  one,  the  Vice
Presidents in the order, if any, established by the Board of Directors shall, in
the absence or incapacity of the  President,  have the authority to exercise all

respectively, shall also have such other authority and perform such other duties

Directors or the  President.  Any Vice  President  may, in the discretion of the
Board of Directors, be designated as "executive", "senior" or by departmental or
functional classification.

                                   ARTICLE 22

                                  THE SECRETARY

        SECTION  22.1 The  Secretary  shall  attend all meetings of the Board of
Directors and of the  shareholders  and keep accurate  records thereof in one or
more minute books kept for that purpose and shall perform the duties customarily
performed  by the  secretary  of a  corporation  and such other duties as may be

        SECTION 24.1 Each assistant  officer shall assist in the  performance of
the duties of the officer to whom such  person is  assistant  and shall  perform
such duties in the absence of the officer.  An assistant  officer  shall perform
such additional  duties as the Board of Directors,  the President or the officer
to whom such person is assistant may from time to time assign such person.  Such
officers may be given such  functional  titles as the Board of  Directors  shall
from time to time determine.

                                   ARTICLE 25

          INDEMNIFICATION OF OFFICERS, DIRECTORS, EMPLOYEES AND AGENTS

        SECTION 25.1 The  Corporation  shall  indemnify any director or officer,
and may indemnify any other  employee or agent,  who was or is a party to, or is
threatened  to be made a party to, or who is called as a witness  in  connection
with, any threatened,  pending, or completed action, suit or proceeding, whether
civil, criminal,  administrative or investigative,  including an action by or in
the right of the Corporation, by reason of the fact that such person is or was a
director, officer, employee or agent of the Corporation, or is or was serving at
the  request of the  Corporation  as a director,  officer,  employee or agent of
another  domestic  or  foreign   corporation,   for  profit  or  not-for-profit,
partnership,  joint  venture,  trust  or  other  enterprise,  against  expenses,
including  attorneys'  fees,  judgments,  fines and amounts paid in  settlement,
actually and reasonably  incurred by him or her in connection  with such action,
suit or proceeding unless the act or failure to act giving rise to the claim for
indemnification is determined by a court to have constituted  willful misconduct
or recklessness.

        SECTION 25.2 The  indemnification  and advancement of expenses  provided
by, or granted pursuant to, this Article 25 shall not be deemed exclusive of any
other rights to which those seeking  indemnification  or advancement of expenses
may be entitled under any Bylaw,  agreement,  contract,  vote of shareholders or
directors or otherwise, both as to action in his or her official capacity and as
to action in another capacity while holding such office. It is the policy of the
Corporation that  indemnification  of, and advancement of expenses to, directors
and officers of the Corporation shall be made to the fullest extent permitted by
law. To this end, the provisions of this Article 25 shall be deemed to have been
amended for the benefit of directors and officers of the  Corporation  effective
immediately upon any modification of the BCL or any modification, or adoption of
any other law that expands or enlarges the power or obligation  of  corporations
organized  under the BCL to  indemnify,  or advance  expenses to,  directors and
officers of corporations.

        SECTION 25.3 The Corporation  shall pay expenses  incurred by an officer
or director,  and may pay expenses  incurred by any other employee or agent,  in
defending an action, or proceeding  referred to in this Article 25 in advance of
the  final  disposition  of  such  action  or  proceeding  upon  receipt  of  an
undertaking  by or on behalf of such  person  to repay  such  amount if it shall
ultimately be determined  that such person is not entitled to be  indemnified by
the Corporation.

        SECTION 25.4 The  indemnification  and advancement of expenses  provided
by, or granted  pursuant to, this Article 25 shall,  unless  otherwise  provided
when  authorized  or  ratified,  continue  as to a person who has ceased to be a
director,  officer,  employee  or agent and shall  inure to the  benefit  of the
heirs, executors and administrators of such person.

        SECTION 25.5 The  Corporation  shall have the authority to create a fund
of any nature,  which may,  but need not, be under the control of a trustee,  or
otherwise  secure or  insure in any  manner,  its  indemnification  obligations,
whether  arising under these Bylaws or otherwise.  This authority shall include,
without  limitation,  the authority to: (a) deposit funds in trust or in escrow;
(b) establish any form of self-insurance; (c) secure its indemnity obligation by
grant of a  security  interest,  mortgage  or other  lien on the  assets  of the
Corporation; or (d) establish a letter of credit, guaranty or surety arrangement
for  the  benefit  of  such   persons  in   connection   with  the   anticipated
indemnification or advancement of expenses  contemplated by this Article 25. The
provisions   of  this   Article  25  shall  not  be  deemed  to   preclude   the
indemnification  of, or  advancement  of  expenses  to,  any  person  who is not
specified in Section 25.1 of this  Article 25 but whom the  Corporation  has the
power or  obligation  to  indemnify,  or to  advance  expenses  for,  under  the
provisions of the BCL or otherwise.  The authority  granted by this Section 25.5
shall be exercised by the Board of Directors of the Corporation.

        SECTION 25.6 The  Corporation  shall have the  authority to enter into a
separate indemnification agreement with any officer, director, employee or agent
of the Corporation or any subsidiary  providing for such indemnification of such
person  as the Board of  Directors  shall  determine  up to the  fullest  extent
permitted by law.

        SECTION  25.7  As  soon  as  practicable  after  receipt  by any  person
specified in Section 25.1 of this  Article 25 of notice of the  commencement  of
any action,  suit or  proceeding  specified  in Section 25.1 of this Article 25,
such  person  shall, if a claim  with respect thereto  may be  made  against the

                                       40


Corporation under Article 25 of these Bylaws,  notify the Corporation in writing
of the  commencement or threat thereof;  however,  the omission so to notify the
Corporation  shall not relieve the Corporation  from any liability under Article
25 of these Bylaws unless the Corporation shall have been prejudiced  thereby or
from any other  liability  which it may have to such  person  other  than  under
Article 25 of these  Bylaws.  With  respect to any such  action as to which such
person  notifies the  Corporation of the  commencement  or threat  thereof,  the
Corporation may participate  therein at its own expense and, except as otherwise
provided herein,  to the extent that it desires,  the Corporation,  jointly with
any other indemnifying party similarly notified, shall be entitled to assume the
defense  thereof,  with counsel  selected by the  Corporation  to the reasonable
satisfaction of such person. After notice from the corporation to such person of
its election to assume the defense thereof,  the Corporation shall not be liable
to such person under Article 25 of these Bylaws for any legal or other  expenses
subsequently  incurred by such  person in  connection  with the defense  thereof
other than as  otherwise  provided  herein.  Such person shall have the right to
employ his or her own counsel in such action,  but the fees and expenses of such
counsel  incurred  after notice from the  Corporation  of its  assumption of the
defense  thereof  shall  be at the  expense  of  such  person  unless:  (a)  the
employment  of  counsel  by  such  person  shall  have  been  authorized  by the
Corporation; (b) such person shall have reasonably concluded that there may be a
conflict of interest  between the  Corporation and such person in the conduct of
the defense of such  proceeding;  or (c) the Corporation  shall not in fact have
employed counsel to assume the defense of such action.

        The  Corporation  shall not be  entitled  to assume  the  defense of any
proceeding brought by or on behalf of the Corporation or as to which such person
shall have  reasonably  concluded  that there may be a conflict of interest.  If
indemnification  under Article 25 of these Bylaws or  advancement of expenses is
not paid or made by the  Corporation,  or on its behalf,  within 90 days after a
written claim for  indemnification  or a request for an  advancement of expenses
has been received by the  Corporation,  such person may, at any time thereafter,
bring suit against the  Corporation to recover the unpaid amount of the claim or
the advancement of expenses.  The right to  indemnification  and advancements of
expenses provided  hereunder shall be enforceable by such person in any court of
competent  jurisdiction.  The  burden of  proving  that  indemnification  is not
appropriate shall be on the Corporation.  Expenses  reasonably  incurred by such
person in connection with successfully establishing the right to indemnification
or  advancement of expenses,  in whole or in part,  shall also be indemnified by
the Corporation.

        SECTION  25.8 The  Corporation  shall  have the  power to  purchase  and
maintain  insurance  on behalf of any person who is or was a director,  officer,
employee or agent of the Corporation, or is or was serving at the request of the
Corporation  as a director,  officer,  employee or agent of another  domestic or
foreign  corporation for profit or not-for-profit,  partnership,  joint venture,
trust or other enterprise against any liability asserted against such person and
incurred  by such  person in any such  capacity,  or  arising  out of his or her
status as such, whether or not the Corporation would have the power to indemnify
such person against such liability under the provisions of this Article 25.

                                   ARTICLE 26

                           SHARES; SHARE CERTIFICATES

        SECTION 26.1 All shares issued by the  Corporation  shall be represented
by certificates. The share certificates of the Corporation shall be numbered and
registered  in a share  register  as they  are  issued;  shall  state  that  the
Corporation is incorporated  under the laws of the Commonwealth of Pennsylvania;
shall bear the name of the registered holder, the number and class of shares and
the designation of the series, if any,  represented  thereby,  the par value, if
any, of each share or a statement that the shares are without par value,  as the
case may be;  shall be signed by the Chairman of the Board,  the  President or a
Vice President,  and the Secretary or the Treasurer or any other person properly
authorized by the Board of Directors,  and shall bear the corporate seal,  which
seal may be a facsimile engraved or printed.  Where the certificate is signed by
a transfer agent or a registrar,  the signature of any corporate officer on such
certificate may be a facsimile engraved or printed.  In case any officer who has
signed, or whose facsimile signature has been placed upon, any share certificate
shall have ceased to be such officer because of death,  resignation or otherwise
before the  certificate is issued,  such share  certificate may be issued by the
Corporation  with the same effect as if the officer had not ceased to be such at
the date of its issue.

                                   ARTICLE 27

                               TRANSFER OF SHARES

        SECTION 27.1 Upon surrender to the  Corporation  of a share  certificate
duly  endorsed  by the  person  named in the  certificate  or by  attorney  duly
appointed  in writing and  accompanied  where  necessary  by proper  evidence of
succession,  assignment  or authority to transfer,  a new  certificate  shall be
issued to the person entitled thereto and the old certificate  cancelled and the
transfer recorded on the share register of the Corporation.  Except as otherwise
provided  pursuant  to  Section  6.2  hereof,  a  transferee  of  shares  of the
Corporation  shall not be a record holder of such shares  entitled to the rights
and benefits  associated  therewith unless and until the share transfer has been
recorded on the share  transfer books of the  Corporation.  No transfer shall be
made if it would  be  inconsistent  with  the  provisions  of  Article  8 of the
Pennsylvania Uniform Commercial Code.

                                   ARTICLE 28

                                LOST CERTIFICATES

        SECTION 28.1 Where a shareholder  of the  Corporation  alleges the loss,
theft or destruction of one or more  certificates  for shares of the Corporation
and requests the issuance of a  substitute  certificate  therefor,  the Board of
Directors may direct a new certificate of the same tenor and for the same number
of  shares  to  be  issued  to  such  person upon  such  person's  making  of an


                                       41


affidavit in form satisfactory to the Board of Directors setting forth the facts
in connection therewith,  provided that prior to the receipt of such request the
Corporation  shall not have either  registered a transfer of such certificate or
received  notice  that  such  certificate  has  been  acquired  by a  bona  fide
purchaser.  When  authorizing  such  issue  of a new  certificate  the  Board of
Directors may, in its  discretion  and as a condition  precedent to the issuance
thereof,  require the owner of such lost,  stolen or destroyed  certificate,  or
such person's heirs or legal  representatives,  as the case may be, to advertise
the same in such manner as it shall require  and/or give the  Corporation a bond
in such form and sum and with surety or sureties, with fixed or open penalty, as
shall be satisfactory to the Board of Directors,  as indemnity for any liability
or expense  that it may incur by reason of the  original  certificate  remaining
outstanding.

                                   ARTICLE 29

                                   FISCAL YEAR

        SECTION 29.1 The fiscal year of the  Corporation  shall be as determined
by the Board of Directors.

                                   ARTICLE 30

                   MANNER OF GIVING NOTICE; WAIVERS OF NOTICE

        SECTION  30.1 Except for any notice under  Section 2.3 of these  Bylaws,
which shall be governed by the provisions of Section 2.3, any notice required to
be given to any person  under the  provisions  of these Bylaws shall be given to
the person either personally or by sending a copy thereof:

        (a) By first class or express mail, postage prepaid, or courier service,
charges  prepaid,  to his or her postal  address  appearing  on the books of the
Corporation  or, in the case of written  notice to  directors,  supplied by each
director to the Corporation for the purpose of the notice.  A notice pursuant to
this  subparagraph  shall be deemed to have been  given to the  person  entitled
thereto when  deposited in the United States mail or with a courier  service for
delivery to that person.

        (b) By facsimile transmission,  e-mail or other electronic communication
to his or her  facsimile  number  or  address  for  e-mail  or other  electronic
communications  supplied  by him or her to the  Corporation  for the  purpose of
notice.  Notice pursuant to this subparagraph shall be deemed to have been given
to the person entitled thereto when sent.

        SECTION  30.2 Any notice  required  to be given to any person  under the
provisions of statute,  the  Corporation's  Articles of  Incorporation  or these
Bylaws may be waived in a writing  signed by the person  entitled to such notice
whether before or after the time stated therein. Except as otherwise required by
statute, and except in the case of a special meeting, neither the business to be
transacted  at, nor the purpose of, a meeting need be specified in the waiver of
notice.  In the case of a special meeting of shareholders,  the waiver of notice
shall specify the general nature of the business to be transacted. Attendance of
any person,  whether in person or by proxy,  at any meeting  shall  constitute a
waiver of notice of such  meeting,  except where a person  attends a meeting for
the express  purpose of  objecting,  at the  beginning  of the  meeting,  to the
transaction  of any  business  because the meeting  was not  lawfully  called or
convened.

                                   ARTICLE 31

                                   AMENDMENTS

        SECTION  31.1 These Bylaws may be amended and  repealed,  and new Bylaws
may be adopted,  by the shareholders only if approved by the affirmative vote of
at least  80% of the  outstanding  shares  entitled  to vote at a duly  convened
regular or special  meeting of the  shareholders  duly  convened  after  written
notice to the  shareholders  that the purpose,  or one of the  purposes,  of the
meeting is to consider the amendment or repeal of these  Bylaws.  There shall be
included in, or enclosed with, the notice a copy of the proposed  amendment or a
summary of the changes to be effected thereby.

        SECTION  31.2 These  Bylaws may be amended or  repealed,  and new Bylaws
adopted,  by the  affirmative  vote of a majority of the members of the Board of
Directors at any regular or special meeting duly convened,  subject to the power
of the  shareholders  to  change  such  action  of the  Board  of  Directors  in
accordance with the provisions of Section 31.1 of these Bylaws.
