ITEM 5.           OTHER EVENTS.


     On January 6, 2000,  the Board of  Directors  of Met-Pro  Corporation  (the
"Company")  authorized and declared a dividend  distribution of one Common Stock
Purchase  Right (a "Right")  for each  outstanding  share of common stock of the
Company (the "Common Stock"), to stockholders of record at the close of business
on January 14, 2000 (the "Record Date"). The description and terms of the Rights
are set forth in a Rights  Agreement,  dated as of January 6, 2000 (the  "Rights
Agreement")  between the Company and American  Stock Transfer and Trust Company,
as Rights Agent (the "Rights Agent").

     The summary  description of the Rights set out below is not complete and is
qualified in its entirety by reference to the Rights Agreement,  as the same may
be amended from time to time, which is incorporated herein by reference.

     Each Right,  when  exercisable,  entitles the registered holder to purchase
from the  Company  one share of Common  Stock at a Purchase  Price of $50.00 per
share, subject to adjustment.

     Initially,  the Rights will be attached  to all Common  Stock  certificates
representing  shares then outstanding,  and no separate Rights Certificates will
be distributed. A Distribution Date will occur and the Rights will separate from
the Common  Stock upon the earlier of: (i) the first  business  day  following a
public announcement that an Acquiring Person has acquired  beneficial  ownership
of 15% or more of the  shares of  Common  Stock  then  outstanding  (the  "Stock
Acquisition  Date"),  or (ii) the first business day following the  commencement
of, or the public  announcement  of the intent to  commence,  a tender  offer or
exchange offer that would result in a person or group beneficially owning 15% or
more of such outstanding shares of Common Stock.

     Until the Distribution Date, (i) the Rights will be evidenced by the Common
Stock  certificates and will be transferred with and only with such Common Stock
certificates,  (ii) new Common Stock certificates issued on or after January 14,
2000 will be  deemed  to be  issued  with  Rights  and will  contain a  notation
incorporating  the Rights  Agreement by  reference,  and (iii) the surrender for
transfer of any certificates  for Common Stock  outstanding will also constitute
the transfer of the Rights  associated with the Common Stock represented by such
certificate.

     The Rights are not exercisable  until the Distribution Date and will expire
at the close of business on January 14,  2010,  unless  earlier  redeemed by the
Company as described below. At no time will the Rights have any voting power.

     As soon as practicable  after the Distribution  Date,  Rights  Certificates
will be mailed to  holders  of  record  of the  Common  Stock as of the close of
business  on  the  Distribution  Date  and,  thereafter,   the  separate  Rights
Certificates alone will represent the Rights. Only shares of Common Stock issued
prior to the Distribution Date will be issued with Rights.

     In the event that an Acquiring  Person becomes the beneficial  owner of 15%
or more of the then outstanding  shares of Common Stock,  each holder of a Right
will thereafter  have the right to receive,  upon payment of the Purchase Price,
Common Stock (or, in certain  circumstances,  cash, property or other securities

                                      -1-



of the  Company)  having a value  (based  on a formula  set forth in the  Rights
Agreement)  equal to two times the Purchase Price of the Right.  Notwithstanding
any of the  foregoing,  following the  occurrence of the event set forth in this
paragraph  (the  "Flip-in  Event"),  all  Rights  that are,  or  (under  certain
circumstances  specified in the Rights Agreement) were, beneficially owned by an
Acquiring Person (or by certain related parties) shall be null and void.

     For  example,  each Right not owned by an  Acquiring  Person (or by certain
related parties of such Acquiring Person) would entitle its holder,  following a
Flip-in Event, to purchase $100.00 worth of Common Stock (or other securities or
consideration, as provided for by the Rights Agreement) determined pursuant to a
formula set forth in the Rights Agreement, for $50.00.

     The term "Acquiring Person" is defined generally in the Rights Agreement as
any person who or which, together with all Affiliates and Associates (as defined
in Rule 12b-2 of the General  Rules and  Regulations  under the  Securities  and
Exchange Act of 1934, as amended) of such person shall be the  Beneficial  Owner
(as defined in the Rights  Agreement)  of 15% or more of the Common Stock of the
Company then outstanding,  but shall not include the Company,  any Subsidiary of
the Company,  any employee  benefit plan of the Company or of any  Subsidiary of
the Company,  or any entity holding Common Stock for or pursuant to the terms of
any such  plan.  Notwithstanding  the  foregoing,  no  person  shall  become  an
"Acquiring  Person"  as the  result of an  acquisition  of  Common  Stock by the
Company  which,  by reducing  the number of shares  outstanding,  increases  the
proportionate  number of shares beneficially owned by such person to 15% or more
of the Common Stock of the Company then outstanding;  provided, however, that if
a person shall become the Beneficial Owner of 15% or more of the Common Stock of
the Company then  outstanding  by reason of the  Company's  purchases of its own
shares  and  shall,  after  such  share  purchases  by the  Company,  become the
Beneficial Owner of any additional Common Stock of the Company, then such person
shall be deemed to be an "Acquiring Person."

     In the event that, at any time  following the Stock  Acquisition  Date, (i)
the Company is acquired in a merger or other business combination transaction in
which  the  Company  is not the  surviving  corporation  or in  which  it is the
surviving corporation but its Common Stock is changed or exchanged, or (ii) more
than 50% of the Company's  assets or earning power is sold or transferred,  each
holder of a Right (except Rights which  previously have been voided as set forth
above)  shall have the right to receive,  upon  payment of the  Purchase  Price,
common  stock of the  acquiring  company  having a value  equal to two times the
Purchase  Price.  The events set forth in this  paragraph  and the Flip-in Event
described in the third  preceding  paragraph are referred to as the  "Triggering
Events."

     The  Purchase  Price  payable,  and the number of shares of Common Stock or
other securities or property  issuable,  upon exercise of the Rights are subject
to adjustment from time to time to prevent  dilution (i) in the event of a stock
dividend on, or a  subdivision,  forward or reverse stock split,  combination or
reclassification  of, the Common Stock,  (ii) if holders of the Common Stock are
granted  certain rights or warrants to subscribe for Common Stock or convertible
securities at less than the current  market price of the Common Stock,  or (iii)
upon  the   distribution  to  holders  of  the  Common  Stock  of  evidences  of
indebtedness or assets  (excluding  regular quarterly or other periodic or other
cash  dividends  out of the  earnings  or  retained  earnings of the Company or,
following the Distribution  Date, a dividend not out of the earnings or retained
earnings of the  Company  unless the Board at such time shall  determine  not to

                                      -2-



include such a dividend within the exception provided for by this parenthetical)
or of subscription rights or warrants (other than those referred to above).

     With certain exceptions,  no anti-dilution adjustment in the Purchase Price
will be  required  until  cumulative  adjustments  amount  to at least 1% of the
Purchase Price. No fractional shares of Common Stock will be issued and, in lieu
thereof,  an  adjustment  in cash will be made based on the market  price of the
Common Stock on the last trading date prior to the date of exercise.

     At any time until any Person shall become an Acquiring Person,  the Company
may redeem the Rights in whole, but not in part, at a price of $0.0001 per Right
(payable  in  cash,  shares  of  Common  Stock  or  other  consideration  deemed
appropriate by the Board of Directors). Immediately upon the action of the Board
of Directors  ordering  redemption of the Rights,  the Rights will terminate and
the  only  right  of the  holders  of  Rights  will be to  receive  the  $0.0001
redemption  price.  The Board may also  redeem the Rights  under  certain  other
circumstances.


         Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of the Company, including, without limitation, the right
to vote or to receive dividends.  While the distribution of the Rights will not
be taxable to stockholders or to the Company, stockholders may, depending upon
the circumstances, recognize taxable income in the event that the Rights become
exercisable for shares of Common Stock (or other consideration) of the Company
or for shares of common stock of the acquiring company as set forth above, or
are redeemed as provided above.

     Any of the  provisions of the Rights  Agreement may be amended by the Board
of Directors  of the Company in its sole  discretion  prior to the  Distribution
Date. After the Distribution Date, the provisions of the Rights Agreement may be
amended by the Board in order to cure any  ambiguity,  to make changes  which do
not adversely affect the interests of holders of Rights (other than an Acquiring
Person or an affiliate or  associate  thereof),  to shorten or lengthen any time
period under the Rights  Agreement,  or to correct or  supplement  any provision
contained in the Rights  Agreement which may be defective or  inconsistent  with
any other provision therein;  provided,  however, that any amendment to lengthen
the time period is for the purpose of enhancing,  protecting  or clarifying  the
rights  and/or  benefits of Rights  holders and that no  amendment to adjust the
time period  governing  redemption  shall be made at such time as the Rights are
not redeemable.

     The Rights Agreement,  dated as of January 6, 2000, between the Company and
American Stock Transfer & Trust Company, as Rights Agent, specifying the term of
the Rights is included as an Exhibit to this filing and is  incorporated  herein
by  reference.  The  foregoing  description  of the Rights is  qualified  in its
entirety by reference to such exhibit,  and in the event of any conflict between
the  description  herein  and the  terms of the  Rights  Agreement,  the  Rights
Agreement shall govern and prevail.
