                                   THE COMPANY

Met-Pro Corporation (the "Company") was organized in 1967 and has grown both
internally and through acquisitions. It designs, manufactures and distributes
products sold for pollution control and fluid handling. The Company operates
through seven divisions and three wholly-owned subsidiaries.

The Stiles-Kem Division is a leading manufacturer of specialty chemicals for the

distributors located in the United States, Mexico and Canada.

The Sethco Division, located on Long Island, New York, designs, manufactures and
sells corrosion resistant pumps, filter chambers and filter systems with flow
rates to about 200 gallons per minute. These products are used in waste water
treatment systems and fume scrubbers for pollution control. They are also widely
used in the metal finishing industry, electronics industry and chemical
processing industry. Sethco products are sold through a network of non-exclusive
distributors, as well as to original equipment manufacturers and catalog houses.

The Mefiag Division, operating through two wholly-owned subsidiaries, designs

superior performance, particularly in high efficiency and high-flow applications
in the plating and metal finishing industries and elsewhere. Worldwide sales are
accomplished through qualified, market-based distributors and original equipment
manufacturers located throughout Europe, the United States, South America and
other major markets.

The Systems Division, located at the Company's principal executive offices in

designs, manufactures and installs major air and water pollution control
systems. Systems Division's air pollution control capabilities include: carbon
adsorption systems for the concentration and recovery of volatile solvents,
thermal and catalytic oxidation systems and the supply of abatement catalysts.
These systems are custom engineered for clients in the automotive, aerospace and
furniture industries. These products also have a variety of applications in the
painting, pharmaceutical, chemical, electronics, food processing and printing
industries. Systems Division also manufactures a full range of catalytic
converters for stationary engines and cogeneration plants to greatly reduce smog
producing and toxic gases, such as NOx, CO and residual hydrocarbons, which are
emitted from these sources.

The Duall Division is a leading manufacturer of industrial and municipal air
pollution control equipment. Its major products include odor control systems,
fume and emergency gas scrubbers, stripping towers and exhaust fans and plating

                                        3

and process tanks. All equipment is fabricated from corrosion resistant
materials in the Company's Owosso, Michigan manufacturing facilities. Services
include pilot studies, engineering, installation and performance testing. Duall
products are sold both domestically and internationally to the metal finishing,
waste water treatment, composting, food processing, chemical, printed circuit,
semiconductor, pharmaceutical, battery manufacturing and groundwater remediation
markets. Over ninety factory trained manufacturer's representatives sell Duall's
systems to industrial and municipal clients.

The Keystone Filter Division is an established custom pleater and cartridge
manufacturer in the United States. It provides custom designed and engineered
products which are currently used in such diverse applications as the nuclear
power industry, as components in medical equipment and in indoor air quality
equipment. It also provides standard filters for water purification and
industrial applications.

The Fybroc Division is a world leader in the manufacture of fiberglass
reinforced pumps. These pumps provide excellent corrosion resistance for tough
applications including pumping of acids, brines, caustics, bleaches and a wide
range of waste liquids. Fybroc pumps are sold to many markets including the
chemical, steel, pulp and paper, electric utility, aquaculture, aquarium, and
industrial and municipal waste treatment industries. Sales, engineering, and
customer service are provided through a worldwide distributor network.

The Dean Pump Division designs and manufactures high quality pumps that handle a
broad range of industrial applications. Users such as the chemical,
petrochemical, refinery, pharmaceutical, plastics, pulp and paper, and food
processing industries choose Dean Pump products particularly for their high
temperature applications. The Company's manufacturing facility in Indianapolis,
Indiana produces pumps which are sold through an extensive network of
distributors.

Recent Events

On June 5, 1996, the Company announced a 3-for-2 stock split, which was paid on
July 8, 1996 to holders of record on June 18, 1996.

On September 12, 1996, Met-Pro Corporation and Met-Pro Acquisition Corporation,
a wholly-owned subsidiary of Met-Pro Corporation (collectively, "Met-Pro"),
executed an Agreement and Plan of Merger (the "Agreement") with Strobic Air

                                        4

<PAGE>



Corporation ("Strobic"), pursuant to which Strobic was merged with and into
Met-Pro Acquisition Corporation, which then changed its name to Strobic Air
Corporation.

The consideration paid by Met-Pro under the Agreement consisted of 195,920
shares of Met-Pro common stock, cash in the amount of approximately $2.15
million, and a promissory note for $250,000. Met-Pro also granted the former
Strobic shareholders certain registration rights under the Securities Act. Lynn
T. Secrest, one of Strobic's principal former shareholders and its former
president, deposited 40,816 shares of Common Stock of Met-Pro and the $250,000
note into escrow to fund indemnification obligations under the Agreement.

Met-Pro also entered into a three (3) year employment agreement with Mr. Lynn T.
Secrest to serve as vice president and the general manager of Strobic, and
obtained Mr. Secrest's covenant not to compete with Met-Pro for a four (4) year
period.

Met-Pro financed part of the purchase price and obligations of Strobic that were
paid at closing with a loan from Mellon Bank, N.A,. in the amount of $3.5
million.

Strobic designs, manufactures and holds patents on specialty blowers and
industrial fans for applications including laboratories, hospitals,
semi-conductor manufacturing clean rooms, pharmaceutical manufacturing and
chemical and petrol-chemical plants. Strobic conducts its operations in an
approximately 20,000 square foot manufacturing facility on a 2.3 acre parcel
that it owns in Bensalem, Pennsylvania, as well as in a contiguous approximately
16,000 square foot facility that it leases.

Met-Pro also entered into certain agreements with certain former Strobic
stockholders governing the disposition of their Shares (see "Plan of
Distribution").

                                 USE OF PROCEEDS

The net proceeds from the sale of the Shares offered hereby will be received by

(1)      Includes Shares held in escrow under the terms of the Agreement. The
         escrowed Shares may be replaced with the cash value equivalent of such
         replaced Shares, valued at the average of the closing prices per share
         as listed on the American Stock Exchange for the ten (10) trading days
         prior to such replacement. Absent any such replacement, the escrowed
         Shares may not be offered prior to September 11, 1998.
(2)      The three Secrests are brothers; however, each of them disclaims
         ownership of the Shares owned by the others.
(3)      The sale of these Shares is subject to certain restrictions as set
         forth in "Plan of Distribution."

In addition to their role as shareholders of Strobic, Messrs. Lynn Secrest,
Richard Secrest, Ronald Secrest and John Stone were formerly officers and
directors of Strobic. Mr. Lynn Secrest is currently employed by Met-Pro as the
Vice President and General Manager of the wholly-owned subsidiary of the Company
into which Strobic was merged. Except for the foregoing, none of the Selling
Shareholders listed above has held any position, office or other material
relationship within the past three years with the Company or any of its
predecessors or affiliates.

                           DESCRIPTION OF COMMON STOCK

The Company's certificate of incorporation authorizes the issuance of up to
10,000,000 shares of Common Stock, par value $.10 per share. The holders of
Common Stock (i) have equal rights to dividends from funds legally available
therefor, when, as and if declared by the Board of Directors of the Company;
(ii) are entitled to share ratably in all of the assets of the Company available
for distribution to holders of Common Stock upon liquidation, dissolution or
winding up of the affairs of the Company; (iii) do not have preemptive,
subscription or conversion rights, and there are no redemption or sinking fund
provisions applicable thereto; and (iv) are entitled to one vote per share on
all matters upon which shareholders may vote at all meetings of shareholders.
All shares of Common Stock now outstanding are fully paid and non-assessable.
The holders of shares of Common Stock do not have cumulative voting rights,


                                        6

<PAGE>



which means that the holders of more than 50% of such outstanding shares, voting
for the election of directors, can elect all of the directors to be elected, if
they so choose. Directors are divided into three classes. Each year, one class
is elected to hold office for the next three years.

The transfer agent for the Company's Common Stock is Chemical Mellon Shareholder
Services, L.L.C., Overpark Center, 85 Challenger Road, Ridgefield Park, NJ
07660.

                              PLAN OF DISTRIBUTION

Any distribution of the Shares by the Selling Shareholders, or by permitted
pledgees, donee, transferees or other successors in interest, may be effected
from time to time in one or more of the following transactions: (a) to
underwriters who will acquire Shares for their own account and resell them in
one or more transactions, including negotiated transactions, at a fixed public
offering price or at varying prices determined at the time of sale (any public
offering price and any discount or concessions allowed or re-allowed or paid to
dealers may be changed from time to time); (b) through brokers, acting as
principal or agent, in transactions (which may involve block transactions) on
the American Stock Exchange, or on one or more exchanges on which the Common
Stock is then listed, in special offerings, exchange distributions pursuant to
the rules of the applicable exchanges or in the over-the-counter market, or
otherwise, at market prices prevailing at the time of sale, at prices related to
such prevailing market prices, at negotiated prices or at fixed prices; or (c)
directly or through brokers or agents in private sales at negotiated prices, or
by any other legally available means.

The Selling Shareholders and such underwriters, brokers, dealers or agents, upon
effecting a sale of Shares, may be considered "underwriters" as that term is
defined by the Securities Act.

Underwriters participating in any offering made pursuant to this Prospectus (as
amended or supplemented from time to time) may receive underwriting discounts
and commissions, and discounts or concessions may be allowed or re-allowed or
paid to dealers, and brokers or agents participating in such transaction may
receive brokerage or agent's commissions or fees.

At the time a particular offering of Shares is made, to the extent required, a
Prospectus Supplement will be distributed which will set forth the amount of
Shares, the offering price paid by an underwriter for Shares purchased from the
Selling Shareholders, any discounts, commissions and other items constituting
compensation from the Selling Shareholders and any discounts, commissions or
concessions allowed or re-allowed or paid to dealers.

Messrs. Lynn Secrest, Richard Secrest, Ronald Secrest and John Stone as a group
and on behalf of their permitted transferees have agreed to the following
restrictions on open market resale of the Shares through December 11, 1997: (i)
no more than 2,000 Shares may be offered and sold on any trading day, and (ii)
no more than a total of 15,000 Shares may be sold in any calendar month. They
may make unlimited private sales to persons who agree to abide by the above
restrictions. These restrictions do not apply to any sale of Shares in an
underwritten public offering of Shares.

                                        7

<PAGE>




The Company has agreed to process to effectiveness a registration statement
under the Securities Act covering the resale of the Shares and to amend it from
time to time as required to incorporate current significant information until
all the Shares have been sold, but not later than September 11, 1999.

All costs, expenses and fees in connection with the registration statement and
amendments to it will be borne by the Company. Commissions and discounts, if
any, attributable to the sale of the Shares will be borne by the Selling
Shareholders. The Selling Shareholders may agree to indemnify any agent, dealer
or broker-dealer that participates in transactions involving sales of the Shares
against certain liabilities, including liabilities arising under the Securities
Act. The Company and the Selling Shareholders have agreed to indemnify each
other and certain other persons against certain liabilities in connection with
the offering of the Shares, including liabilities arising under the Securities
Act.

Whenever the Company proposes to file a registration statement under the
Securities Act at any time or from time to time prior to September 11, 1999
involving an underwritten public offering, the Company has agreed to include in
any such registration statement any of the Shares that are so requested by the
Selling Shareholders; provided however, that if in the written opinion of the
underwriter or managing underwriter the inclusion of any of such Shares would
materially and adversely affect such public offering, then the number of such

Officers and Directors
Strobic Air Corporation
Bensalem, Pennsylvania

We have audited the accompanying balance sheet of Strobic Air Corporation as of
July 31, 1996, and the related statements of operations, stockholders' equity
and cash flows for the nine months then ended. These financial statements are
the responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Strobic Air Corporation as of
July 31, 1996, and the results of its operations and its cash flows for the nine
months then ended in conformity with generally accepted accounting principles.

     risk consist of cash and accounts receivable. The Company's cash is
     maintained in a high quality financial institution. Concentrations of

     The following methods and assumptions were used to estimate the fair value
     of each financial instrument:

     Cash - The carrying amount approximates fair value because of the short

Officers and Directors
Strobic Air Corporation
Bensalem, Pennsylvania


We have audited the accompanying balance sheet of Strobic Air Corporation as of
October 31, 1995, and the related statements of operations, stockholders'
equity, and cash flows for the year then ended. These financial statements are
the responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Strobic Air Corporation as of
October 31, 1995, and the results of its operations and its cash flows for the
year then ended in conformity with generally accepted accounting principles.

      Note payable, bank                                   520,000     520,000

     The following methods and assumptions were used to estimate the fair value
     of each financial instrument:

     Cash and note payable, individual - The carrying amount approximates fair
     value because of the short maturity of these instruments.

     Note payable, bank and long-term debt - The fair value is based on the
     present value of expected future payments discounted at rates available to
     the Company under similar borrowing arrangements.

11.  Subsequent Event

     On September 12, 1996, the Company entered into an agreement and plan of
     merger whereby it agreed to be merged with and into Met-Pro Acquisition
     Corporation, a wholly-owned subsidiary of Met-Pro Corporation, as part of 
     a tax-free reorganization.

                               MET-PRO CORPORATION

   Explanatory Notes to Pro Forma Consolidated Condensed Financial Statements
                       For the Year Ended January 31, 1996

1.       The pro forma consolidated condensed balance sheet is based on the
         individual balance sheets of Met-Pro Corporation and Strobic Air
         Corporation to reflect the acquisition of Strobic Air Corporation by
         Met-Pro Corporation (which took place on September 12, 1996) as if it
         had taken place on January 31, 1996, after giving effect to pro forma
         adjustments to reflect the following:

         Met-Pro Corporation paid $2,399,980 for 100% of the common stock of
         Strobic Air Corporation of which $2,149,980 was paid on the date of the
         transaction and $250,000 (A) was in the form of a promissory note
         payable on April 2, 1998. Interest is payable on the promissory note at
         the rate of 5.9% per annum. In addition, Met-Pro Corporation exchanged
         195,920 (B) shares of its common stock having an aggregate value of
         $2,400,020 (C).

         As part of the transaction, Met-Pro Corporation entered into a
         non-compete transaction with one of the stockholders of Strobic Air
         Corporation for which he was paid $1,000,000 (D). In addition, a
         sign-on bonus of $350,000 (E) was paid to this stockholder.

         Total cash required at settlement amounted to $3,499,980. Met-Pro
         Corporation financed this transaction with a bank on an unsecured
         basis. The bank financing, in the aggregate amount of $3,500,000 (F),
         is comprised of two notes, one with a floating interest rate and one
         with a fixed interest rate, in the amount of $1,750,000 each. Each loan
         is payable in equal quarterly installments aggregating $175,000,
         commencing on December 31, 1996. Met-Pro Corporation incurred financing
         fees of $8,750 (G) related to this financing.

         Met-Pro Corporation incurred approximately $200,000 (H) in costs
         associated with the transaction, which was funded internally.

         For purposes of the pro forma financial statements, Strobic Air
         Corporation's building was written up by $150,000 (I) to estimated fair
         value.

         The increase in deferred taxes of $60,000 (J) included on the pro forma
         balance sheet is the result of differences between the book basis and
         tax basis of the assets acquired, in compliance with Financial
         Accounting Standards Board Statement No. 109, Accounting for Income
         Taxes.

         As a result of this acquisition, Met-Pro Corporation has increased the
         costs in excess of net assets of businesses acquired by $3,973,537 (K)
         as of January 31, 1996.

         In connection with the acquisition, Met-Pro Corporation repaid all of
         the outstanding debt of Strobic Air Corporation, which at January 31,
         1996 amounted to $840,676 (L).

                  Corporation settled two litigation matters totaling $103,125,

                               MET-PRO CORPORATION

   Explanatory Notes to Pro Forma Consolidated Condensed Financial Statements
                     For the Six Months Ended July 31, 1996

1.       The pro forma consolidated condensed balance sheet is based on the
         individual balance sheets of Met-Pro Corporation and Strobic Air
         Corporation to reflect the acquisition of Strobic Air Corporation by
         Met-Pro Corporation (which took place on September 12, 1996) as if it
         had taken place on July 31, 1996, after giving effect to pro forma
         adjustments to reflect the following:

         Met-Pro Corporation paid $2,399,980 for 100% of the common stock of
         Strobic Air Corporation of which $2,149,980 was paid on the date of the
         transaction and $250,000 (A) was in the form of a promissory note
         payable on April 2, 1998. Interest is payable on the promissory note at
         the rate of 5.9% per annum. In addition, Met-Pro Corporation exchanged
         195,920 (B) shares of its common stock having an aggregate value of
         $2,400,020 (C).

         As part of the transaction, Met-Pro Corporation entered into a
         non-compete transaction with one of the stockholders of Strobic Air
         Corporation for which he was paid $1,000,000 (D). In addition, a
         sign-on bonus of $350,000 (E) was paid to this stockholder.

         Total cash required at settlement amounted to $3,499,980. Met-Pro
         Corporation financed this transaction with a bank on an unsecured
         basis. The bank financing, in the aggregate amount of $3,500,000 (F),
         is comprised of two notes, one with a floating interest rate and one
         with a fixed interest rate, in the amount of $1,750,000 each. Each loan
         is payable in equal quarterly installments aggregating $175,000,
         commencing on December 31, 1996. Met-Pro Corporation incurred financing
         fees of $8,750 (G) related to this financing.

         Met-Pro Corporation incurred approximately $200,000 (H) in costs
         associated with the transaction which was funded internally.

         For purposes of the pro forma financial statements, Strobic Air
         Corporation's building was written up by $150,000 (I) to estimated fair
         value.

         The increase in deferred taxes of $60,000 (J) included on the pro forma
         balance sheet is the result of differences between the book basis and
         tax basis of the assets acquired, in compliance with Financial
         Accounting Standards Board Statement No. 109, Accounting for Income
         Taxes.

         As a result of this acquisition, Met-Pro Corporation has increased the
         costs in excess of net assets of businesses acquired by $3,842,671 (K)
         as of July 31, 1996.

         In connection with the acquisition, Met-Pro Corporation repaid all of
         the outstanding debt of Strobic Air Corporation, which amounted to
         $817,025 (L) at July 31, 1996.

                  described in (M) above.

         (O)      Additional depreciation on the write-up of Strobic Air 
                  Corporation's building amounting to $3,750.

         (Q)      Reduction in interest income by $20,500 due to the cash outlay

                  repay its debt.

         (R)      Interest expense increase of $131,500 as a result of bank
                  financing of $3,500,000 and $250,000 note payable to Strobic
                  Air Corporation stockholder.

         (S)      Amortization of costs in excess of net assets of businesses
                  acquired over 40 years amounting to $48,033.

                  $13,000.

         (U)      Non-recurring professional fees relating to sale of Strobic
                  Air Corporation amounting to $90,000.

         (V)      Non-recurring expenses of Strobic Air Corporation stockholders
                  amounting to $65,000.

         (W)      Reduction in insurance expense of $12,500 based on estimated
                  savings from duplicate coverages between the two companies.

Item 15.     Indemnification of Directors and Officers.

The Company has adopted the provisions of Section 102(b)(7) of the Delaware
General Corporation Act (the "Delaware Act") which eliminate or limit the
personal liability of a director to the Company or its shareholders for monetary
damages for breach of fiduciary duty under certain circumstances. Furthermore,
under Section 145 of the Delaware Act, the Company may, and in certain
circumstances shall, indemnify each of its directors and officers against
expenses (including reasonable costs, disbursements and counsel fees) in
connection with any proceeding involving such person by reason of having been an
officer or director, to the extent such person acted in good faith and in a
manner reasonably believed to be in, or not opposed to, the best interest of the
Company, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe such person's conduct was unlawful. The
determination of whether indemnification is proper under the circumstances,
unless made by a court, shall be made by a majority of a quorum of disinterested
members of the Board of Directors, independent legal counsel or the shareholders
of the Company. The Company has purchased directors and officers liability
insurance providing for up to $2,000,000 of coverage, subject to certain
deductibles.

Item 17.     Undertakings.

The undersigned registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement.

                  (i) To include any Prospectus required by Section 10(a)(3) of
the Securities Act of 1933;

                  (ii) To reflect in the Prospectus any facts or events arising
after the effective date of the registration statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the registration
statement; and

                  (iii) To include any material information with respect to the
plan of distribution not previously disclosed in the registration statement or
any material change to such information in the registration statement;

Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
registration statement is on Form S-3 or Form S-8, and the information required
to be included in a post-effective amendment by those paragraph is contained in
periodic reports filed by the registrant pursuant to Section 13 or Section 15(d)
of the Securities Exchange Act of 1934 that are incorporated by reference in the
registration statement.

         (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at the time shall be deemed to be the initial bona
fide offering thereof.

                                      II-2

<PAGE>



         (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.

The undersigned registrant hereby undertakes that for purposes of determining
any liability under the Securities Act of 1933, each filing of the registrant's
annual report pursuant to Section 13(a) or Section 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefits
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at the time shall be deemed to be
the initial bona fide offering thereof.

The undersigned registrant hereby undertakes to deliver or cause to be delivered
with the Prospectus, to each person to whom the Prospectus is sent or given, the
latest annual report to securityholders that is incorporated by reference in the
Prospectus and furnished pursuant to and meeting the requirements of Rule 14a-3
or Rule 14c-3 under the Securities Exchange Act of 1934; and, where interim
financial information required to be presented by Article 3 of Regulation S-X is
not set forth in the Prospectus, to deliver, or cause to be delivered to each
person to whom the Prospectus is sent or given, the latest quarterly report that
is specifically incorporated by reference in the Prospectus to provide such
interim financial information.

Insofar as indemnification for liabilities arising under the Securities Act of
1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act of 1933 and will be governed by the
final adjudication of such issue.

The undersigned registrant undertakes that:

         (1) For purposes of determining any liability under the Securities Act
of 1933, the information omitted from the form of Prospectus filed as part of
this registration statement in reliance upon Rule 430A and contained in a form
of Prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or
497(h) under the Securities Act of 1933 shall be deemed to be part of this


                                      II-3

<PAGE>


registration statement as of the time it was declared effective.

         (2) For the purpose of determining any liability under the Securities
Act of 1933, each post-effective amendment that contains a form of Prospectus
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

         3.       Disposition of Strobic Shares

                  (a) Conversion of Strobic Shares. At and as of the Effective
Time, by virtue of the Merger and without any action on the part of the holders
thereof:

                           (i) All outstanding Strobic Shares (other than any
Dissenting Shares) shall be converted into the right to receive an aggregate
amount (the "Strobic Merger Consideration") equal to (A) $2,399,980 of which
$2,149,980 shall be payable by wire transfer of immediately available funds at
Closing, and $250,000 shall be represented by Buyer's unsecured Promissory Note
in the form attached hereto and made a part hereof as Exhibit B (the "Note")
payable to Lynn T. Secrest, plus (B) 195,920 Met-Pro Exchange Shares delivered
at Closing having an aggregate Exchange Share Value, pursuant to subparagraph
3(b), in the principal amount of $2,400,020, subject to escrow as provided in
Sections 3(c) and 7 hereof.

                           (ii) All Strobic Shares held by Strobic as treasury
shares, if any, shall be cancelled.

                           (iii) Dissenting Shares, if any, shall not be
converted into or represent a right to receive cash or Met-Pro Exchange Shares
hereunder, but the holders thereof shall be entitled only to such rights as are
granted by the New Jersey General Corporation Law. Strobic shall give Buyer
prompt notice upon receipt by Strobic of any such written demands for appraisal,
withdrawals of demands for appraisal and any other instruments served pursuant
to the New Jersey General Corporation Law (any shareholder duly making such
demand being hereinafter called a "Dissenting Stockholder"). Strobic agrees that
it will not, except with the prior written consent of Buyer, voluntarily make
any payment with respect to , or settle or offer to settle, any such demands.
Each Dissenting Stockholder who, pursuant to the provisions of the New Jersey
General Corporation Law, becomes entitled to payment for his, her or its Strobic
Shares shall receive payment therefor from the Surviving Corporation (but only
after the amount thereof shall have been agreed upon or finally determined
pursuant to such provisions) and such Strobic Shares shall thereafter be
cancelled.

                           (iv) At the Closing, the stock transfer books of
Strobic shall be closed and no transfer of Strobic Shares shall thereafter be

                                        7

<PAGE>



made. If, after the Effective Date, certificates representing Strobic Shares are
presented to the Surviving Corporation, they shall be cancelled and exchanged
for the pro rata amount of Met-Pro Exchange Shares and cash in accordance with
this Agreement.

                  (b) Met-Pro Exchange Shares. At and as of the Effective Time,
each Met-Pro Exchange Share shall be deemed equal to $12.25 (the "Exchange Share
Value"). The aggregate number of the Met-Pro Shares receivable upon conversion
shall be One Hundred Ninety Five Thousand Nine Hundred and Twenty (195,920) (the
"Met-Pro Exchange Shares"), subject to escrow as provided in Sections 3(c) and 7
hereof. The manner and basis of converting the Strobic Shares, and the number of
Met-Pro Shares receivable upon conversion (the "Met-Pro Exchange Shares") on and
after the Effective Time, shall be calculated as follows: each Strobic Share,
with the exception only of the Dissenting Shares, and treasury shares shall be
converted into 79.1596 Met-Pro Exchange Shares.

                  (c) Escrow. Anything contained hereinabove to the contrary
notwithstanding, of the Two Million Three Hundred Ninety Nine Thousand Nine
Hundred Eighty Dollars ($2,399,980) in cash and by the Note and the Two Million
Four Hundred Thousand Twenty Dollars ($2,400,020) payable in Met-Pro Exchange
Shares to the Strobic shareholders, Two Hundred Fifty Thousand Dollars
($250,000) represented by the Note and Forty Thousand Eight Hundred Sixteen
(40,816) Met-Pro Exchange Shares (valued at $12.25 per share for purposes of
this Agreement) shall be withheld from Lynn T. Secrest and shall be deposited in
escrow with the Escrow Agent as security for the Named Shareholders'
indemnification obligations under Section 7(a) pursuant to a certain Escrow
Agreement to be executed at Closing, in the form set forth on Exhibit C attached
hereto and made part hereof (the "Escrow Agreement").

                  (d)      Procedure for Payment.

                           (i) Immediately after the Effective Time, each holder
of Strobic Shares other than Lynn T. Secrest, upon surrender of properly
endorsed certificates of Strobic Shares, shall be entitled to receive the cash
distribution and a certificate representing the number of Met-Pro Exchange
Shares to which such holder is entitled. Lynn T. Secrest shall be entitled to
receive the cash distribution and a certificate representing the number of
Met-Pro Exchange Shares to which he is entitled minus the Notes and Met-Pro
Exchange Shares withheld for deposit in escrow pursuant to Section 3(c) hereof.

                           (ii) Met-Pro will not pay any dividend or make any
distribution on Met-Pro Exchange Shares to any record holder of outstanding
Strobic Shares until the holder surrenders for exchange the certificate(s) which
represented Strobic Shares.

                  (e) Restrictions on Sale of Met-Pro Exchange Shares. The Named
Shareholders agree, notwithstanding the registration of the Met-Pro Exchange
Shares pursuant to Section 5(g) hereof, that for a period of fifteen (15) months

                                        8

<PAGE>



after the Closing (the "Lock Up Period"), the aggregate of the Met-Pro Exchange
Shares sold by them as a group, inclusive of sales by any Permitted Transferee,
shall not exceed (i) 15,000 Met-Pro Exchange Shares in any calendar month, and
(ii) 2,000 Met-Pro Exchange Shares in any trading day. The numbers of Met-Pro
Exchange Shares aforementioned shall not be increased for any stock dividend or
upon Met-Pro's first stock split after the Closing but shall be increased in the
identical ratio of a stock split in the event of any stock splits subsequent to
such first stock split. During the Lock Up Period, the Named Shareholders agree
to deliver to Met-Pro no later than the tenth (10th) day of each month a written
report stating the number of Met-Pro Exchange Shares sold each day of the
preceding month by the Named Shareholders and their Permitted Transferees. No
entry will be required for days on which there were no sales, however, for any
month in which no sales were made, a written report so stating shall be
submitted. Met-Pro agrees to use its best efforts to advise the Named
Shareholders of any written expressions of interest by any institutional or
other potentially significant private buyers of Met-Pro stock during the Lock Up
Period. The trading restrictions set forth in this Section 3(e) shall not apply
to the following:

                           (i) private sales to any Person, or sales, gifts or
other transfers to Permitted Transferees not occurring through the facilities of
the American Stock Exchange that the Stockholders may arrange; provided,
however, that as a condition of giving effect to any such purported transfer,
the purchaser or Permitted Transferee thereof shall execute and deliver unto
Met-Pro a written agreement agreeing to be bound by the provisions of this
Section 3(e ); and

                           (ii) Any sale of Met-Pro Exchange Shares sold by the
Named Stockholders in an underwritten public offering of the Met-Pro Exchange
Shares; provided, however, that the Named Stockholders agree to be bound by any
restrictions imposed by Met-Pro or any underwriter upon any other participant in
such underwritten distribution, upon the same terms and conditions.

<PAGE>



31, 1989. No Tax Returns have been audited or are currently the subject of
audit. Strobic has delivered to Buyer correct and complete copies of all federal
and state income Tax Returns.

                           (iv) Strobic has not waived any statute of
limitations in respect of Taxes or agreed to any extension of time with respect
to a Tax assessment or deficiency.

                           (v) The unpaid Taxes of Strobic did not, as of the
Audited Stub Financial Statement, exceed the reserve for Tax Liability (rather
than any reserve for deferred Taxes established to reflect timing differences
between book and Tax income) set forth in the Audited Stub Financial Statements.

                           (vi) None of the Liabilities is an obligation to make
a payment that will not be deductible under Code Section 280G. Strobic has
disclosed on its federal income Tax Returns all positions taken therein that
could give rise to a substantial understatement of federal income Tax within the
meaning of Code Section 6662. Strobic is not a party to any Tax allocation or
sharing agreement. Strobic (A) has not been a member of an Affiliated Group
filing a consolidated federal income Tax Return (other than a group the common
parent of which was Strobic), and (B) has no Liability for the Taxes of any
Person (other than Strobic) under Treas. Reg. Section 1.1502-6 (or any similar
provision of state, local, or foreign law), as a transferee or successor, by
contract, or otherwise.

                  (g) Regulatory Matters and Met-Pro Exchange Shares. Met-Pro
will prepare and file with the SEC a registration statement, including a
prospectus, under the Securities Act relating to the offering and sale of the
Met-Pro Exchange Shares (the "Registration Statement") within thirty (30) days
following the Closing. Met-Pro will use its reasonable best efforts to respond
to the comments of the SEC thereon and to make any further filings (including
amendments and supplements) in connection therewith that may be necessary and
will take all actions that may be necessary, proper, or advisable under state
securities laws in connection with the offering and sale of Met-Pro Shares so as
to obtain the effectiveness of the Registration Statement no later than ninety
(90) days after the Closing Date. Met-Pro will provide Strobic, and Strobic will
provide Met-Pro, with whatever information and assistance in connection with the
foregoing filings that the Parties may request. In the event that despite

                                       26

<PAGE>



Met-Pro's best efforts, the SEC shall not have declared the Registration
Statement effective within ninety (90) days after the Closing Date, Met-Pro
shall continue to utilize its best efforts to obtain the effectiveness of the
Registration Statement until such time as the Registration Statement shall be
declared effective by the SEC.

                  (h) Disclosure. At all times after the Registration Statement
is filed and during the period the Registration Statement is required to be
effective: (i) the Registration Statement and any Prospectus will comply with
the Securities Act and the rules and regulations thereunder in all material
respects; and (ii) the Registration Statement and the Prospectus will not
contain any untrue statement of a material fact or omit to state a material fact
necessary in order to make the statements made therein, in the light of the
circumstances under which they will be made, not misleading; provided, however,
that neither Buyer nor Met-Pro makes any representation or warranty with respect
to any information that Strobic will supply specifically for use in the
Registration Statement and the Prospectus.

                           (i) Buyer and Met-Pro will each give any notices to,
make all filings with, and use its reasonable best efforts to obtain any
authorizations, consents, and approvals of governments and governmental agencies
in connection with the matters referred to in this Section 5(h), Section 3(b),
Section 4(ac) and Section 5(g) above. Without limiting the generality of the
foregoing, Met-Pro shall diligently pursue and obtain effectiveness of the
Registration Statement with respect to the Met-Pro Exchange Shares and shall
maintain the effectiveness of such Registration Statement for a period of three
(3) years following the effective date with the SEC or such shorter period as
the Named Shareholders and their Permitted Transferees shall hold Met-Pro
Exchange Shares.

                           (ii) Met-Pro agrees to furnish to the Stockholders
and their Permitted Transferees from time to time such number of copies of a
Prospectus, including a preliminary prospectus, in conformity with the
requirements of the Securities Act, and such other documents, as the
Stockholders and their Permitted Transferees may reasonably request in order to
facilitate the public sale or other disposition of such Met-Pro Exchange Shares.

                           (iii) Whenever Met-Pro proposes to file a
registration statement at any time or from time to time after the Closing prior
to the third anniversary of the Closing wherein the Met-Pro Shares being
registered thereunder are proposed to be distributed in a public offering by or
through an underwriter or underwriters, Met-Pro will, prior to such filing, give
written notice to the Stockholders, through Lynn T. Secrest, (the "Stockholder
Representative"), of its intention to do so (which notice shall include a
statement of the terms and conditions of the proposed underwritten
distribution). Upon the written request of Stockholders or any of them, given
through the Stockholder Representative within 20 days after receipt of any such
notice, Met-Pro will include in such registration (and any related qualification
under Blue Sky or other compliance filings) all Met-Pro Exchange Shares which
Met-Pro has been requested by the Stockholders to so include; provided, however,
that if, in the written opinion of the underwriter or managing underwriter the

                                       27

<PAGE>



inclusion of all or part of the Met-Pro Exchange Shares which the Stockholders
have requested to be included, together with the shares of any other selling
shareholder proposed to be included in such offering ("Other Shares"), would
materially and adversely affect such public offering, then the number of Met-Pro
Exchange Shares and Other Shares to be included in such offering shall be
proportionally reduced so that Met-Pro shall be required to include only that
number of Met-Pro Exchange Shares and Other Shares, if any, which the
underwriter or managing underwriter reasonably believes may be sold without
causing such adverse effect. In connection therewith, the Stockholders shall
enter into an underwriting agreement with the underwriter or underwriters
selected for underwriting by Met-Pro.

                           (iv) If Met-Pro has delivered preliminary or final
prospectuses to the Stockholders pursuant to Sections 5(h)(i) or 5(h)(iii)
hereof, and after having done so the prospectus should be amended to comply with
the requirements of the Securities Act, Met-Pro shall promptly notify the
Stockholders, and if requested, the Stockholders shall immediately cease making
offers of Met-Pro Exchange Shares and return all prospectuses relating to such
registration to Met-Pro. Met-Pro shall promptly amend its registration statement
and provide the Stockholders with revised prospectuses, and following receipt of
the revised prospectuses, the Stockholders shall be free to resume making offers
of the Met-Pro Exchange Shares in accordance with the terms thereof.

                           (v) "Registration Expenses" shall mean all expenses
pertaining to the registration of the Met-Pro Exchange Shares incurred by
Met-Pro in complying with Sections 5(g) and this Section 5(h), including,
without limitation, all registration and filing fees, printing expenses, fees
and disbursements of counsel and accountants for Met-Pro, and the expense of any
special audits incident to or required by any such registration, but excluding
underwriting discounts and selling commissions and selling expenses.
Registration Expenses incurred as a result of the registration made pursuant to
Sections 5(g) and 5(h)(i) hereof, whether or not Met-Pro Exchange Shares are
sold pursuant thereto, and all Registration Expenses incurred as a result of any
registration made pursuant to Section 5(h)(iii) hereof, shall be borne by
Met-Pro.

                           (vi) Upon receipt of written notice no less than
thirty (30) days prior to the third anniversary of the Closing, Met-Pro agrees
to repurchase on the third anniversary of the Closing, at the Exchange Share
Value of $12.25 set forth in Section 3(c) above, all or, at the sole option of
the Stockholder(s), less than all, of the Met-Pro Exchange Shares, if any, held
by the Stockholders or their Permitted Transferees (the "Put Right"). The Put
Right, together with the Met-Pro Exchange Shares, shall be assignable to
Permitted Transferees; provided, however, that such Permitted Transferees shall
not have the further right to reassign the Put Right to a non-Permitted
Transferee.

                  (i) Tax Matters. It is the intent of the Parties that the
transactions hereunder qualify as a tax-free reorganization within the meaning
of Section 368(a)(1)(A) of the Code ("Tax Free Status"). Met-Pro and Buyer will
take all such action as is required in order to give effect to the intent of the
Parties for Federal, state and local Tax purposes to the extent permitted by
law; provided, however, that compliance with any request by the Named

                                       28

<PAGE>



Shareholders or their Permitted Transferees relating to disposition of the
Met-Pro Exchange Shares shall not be deemed a waiver of any right by Buyer or
Met-Pro to assert any indemnification claim under Section 7 hereof. Met-Pro will
not merge Buyer into Met-Pro for a period of three years following Closing and
it is the present intention of Buyer to continue at least one significant
historic business line of Strobic, or to use at least one significant portion of
Strobic's historic business assets in a business, in each case within the
meaning of Treas. Reg. Section 1.368-1(d). Buyer or Met-Pro may elect, at its
sole discretion to waive any statute of limitations in respect to Taxes or agree
to any extension of time with respect to a Tax assessment or deficiency relating
to or arising out of any IRS examination.

until such Damages, on a cumulative basis, exceed Forty Thousand Dollars
($40,000) in which event the Named Shareholders shall jointly and severally be
liable for all Damages, without regard to the $40,000 limitations herein, and
(2) the aggregate indemnity obligations of the Named Shareholders under 7(a)(i)
shall not exceed Two Million Dollars ($2,000,000) excluding, however, Damages
relating to claims based on representations and warranties in Sections 4(k) and
exclusive of interest due on any Damages pursuant to Section 7(d)(B) hereof.

                                    (C) Notwithstanding the foregoing, the
limitation on indemnification set forth in this Section 7(a)(ii) shall not apply
to Named Shareholders in the event Strobic or Secrest has Knowledge of a breach
of a representation or warranty by Strobic or Secrest on or prior to the Closing
Date.

                  (b) Indemnification by Buyer and Met-Pro.

                           (i) Subject to the provisions of 7(b)(ii) below,
Buyer and Met-Pro agree to indemnify and hold harmless Named Shareholders from
and against all Damages with respect to Buyer or Met-Pro suffered by Named
Shareholders as a direct or indirect result of:

                                    (A) the inaccuracy of any representation or
warranty made by Buyer or Met-Pro with respect to Buyer or Met-Pro in or
pursuant to this Agreement (including, without limitation, Section 5, provided,
however that solely for purposes of calculating Damages arising from an
indemnification claim for such inaccuracy hereunder, all such representations
and warranties shall be read as if they contained no "knowledge" or
"materiality" condition);

                                    (B) any failure by Buyer or Met-Pro to
perform any obligation or comply with any covenant or agreement specified herein
(including without limitation the covenants set forth in any other document
executed simultaneously herewith);

                                    (C) any other claims of a third party
(including, without limitation, claims alleging death or injury to persons or
damage to property caused by, or resulting from, any defect or claimed defect
in or with respect to products or services of Strobic (whether based in equity,
tort or contract), any tort, default in the performance or breach of any
contract or commitment, or for consequential, special or punitive damages) for
all conditions, acts or failures to act of Buyer or Met-Pro or other occurrences
subsequent to the Closing Date or resulting from or caused by any product
purchased for resale, manufactured or sold, or service provided, by Buyer or
Met-Pro after the Closing Date; and

                                    (D) any untrue statement or alleged untrue
statement of any material fact contained in any registration statement under
which the Met-Pro Exchange Shares were registered under the Securities Act, any
preliminary prospectus or final prospectus contained in the registration
statement, or any amendment or supplement to the registration statement, or an
omission or alleged omission to state such a material fact required to be stated
therein or necessary to make the statements therein not misleading, unless such
statement or omission was based upon information furnished or resulting from the
omission of information which should have been furnished in order to make such
statements not misleading by or on behalf of Strobic or the Named Shareholders,
or arising out of or based upon any other violation by the Named Shareholders of
any Federal or state securities law or rule or regulation thereunder.

                           (ii) The obligations and liabilities of Buyer and
Met-Pro under Section 7(b)(i) shall be subject to the following terms and
conditions:

                                    (A) the right of Named Shareholders to be
indemnified for Damages pursuant to Section 7(a)(i) shall apply only if asserted
by Named Shareholders before the third anniversary of the date hereof;


                                       34

<PAGE>



                                    (B) Notwithstanding the foregoing, the
limitation on indemnification set forth in this Section 7(a)(ii) shall not apply
to Buyer or Met-Pro in the event Buyer or Met-Pro has Knowledge of a breach of a
representation or warranty with respect to such claim on or prior to the date
hereof.

                  (c) Escrow Account. For the purposes of providing assets for
any indemnification by the Named Shareholders which may be required under
Section 7 hereof, the Note in the principal amount of $250,000 and Forty
Thousand Eight Hundred Sixteen (40,816) Met-Pro Exchange Shares shall be
withheld from payment of the Strobic Merger Consideration to Secrest and shall
be set aside in an escrow account (the "Escrow Account") pursuant to the terms
of the Escrow Agreement. In the event Buyer or Met-Pro asserts any claim for
indemnification against the Escrow Account, it is hereby agreed that amounts due
under the Note shall first be applied in satisfaction of Damages and,
thereafter, Met-Pro Exchange Shares shall be applied, valued at the average of
the closing prices per share of the Met-Pro Shares as listed on the American
Stock Exchange over a period of ten (10) trading days after notification of such
claim. Pursuant to the terms of the Escrow Agreement, any deliverance of the
Note or Met-Pro Exchange Shares to Secrest from the Escrow Account shall be made
net of any reduction required by resolved claim(s) and any reserve for pending
indemnification claims. In the event that the Escrow Account is insufficient to
pay all Damages to Buyer and Met-Pro, including by virtue of the expiration of
the escrow period, the Named Shareholders shall be liable for the difference,
subject to the limitations on liability in Sections 7(a)(ii). During the term of
the Escrow Agreement, Secrest shall have the right to replace any or all of the
Met-Pro Exchange Shares held in the Escrow Account with the cash value
equivalent of such replaced shares, valued at the average of the closing prices
per share of such shares as listed on the American Stock Exchange for the ten
(10) trading day prior to such replacement.

                  (d) Definition of "Damages".

                           (i) For the purpose of this Section 7, the term
"Damages" shall be determined and computed by reference to the effect of the
compensable event on the party or parties entitled thereto, and shall be deemed
to include (A) all damages, losses, liabilities, claims, deficiencies, expenses
or costs incurred by such party or parties, including reasonable attorney's and
accounting fees, and reasonable amounts paid in investigation, defense and/or
settlement of any of the foregoing, excluding only punitive and exemplary
damages, and (B) interest at a rate per annum equal to that announced from time
to time by Mellon Bank, N.A. as its highest "prime rate" from the date 30 days
after notice of any such claim for indemnification under this Section 7 is
given, or if an unliquidated claim, from such later date as the claim is
liquidated, to the date full indemnification is made therefor. Damages shall not
include any amounts for which an indemnified party actually receives payment
under an insurance policy, excluding self-insured amounts and deductible
amounts, and shall reflect any federal, state, local or foreign income tax net
benefit ("Tax Benefit") which Met-Pro or Buyer can actually realize as a result
of such Damages; provided that, the Tax Benefit shall be determined by an
independent certified public accounting firm satisfactory to both Buyer and

                                       35

<PAGE>



Seller at the Named Shareholders' sole expense. The Tax Benefit shall be based
upon a reasonable estimate of future tax savings attributable to the deductions
resulting from any increases in the tax basis of assets associated with the Tax
Liability. The value of any such future savings shall be determined using tax
concepts, including any appropriate valuation allowances that account for the
possibility that certain Tax Benefits will never be realized, and for the
determination of appropriate tax rates. The calculation will also take into
account Strobic Merger Consideration allocations determined by Buyer and the use
of present value concepts using the above referenced interest rate. If Buyer and
Seller are unable to agree on such a firm, Buyer and Seller shall each select an
independent certified public accounting firm and these two together shall select
a third independent certified public accounting firm, whose determination as to
the Tax Benefit, if any, shall be binding and conclusive on the Parties.

                           (ii) If a claim for indemnification under Section
4(u) is made by Buyer or Met-Pro, the following terms and conditions shall
apply:

                                    (A) warranty Damages will be deemed to
include the costs of all direct materials, direct labor and overhead, plus
out-of-pocket expenses and third party costs (subcontract), if applicable, for
the replacement or repair of Strobic products that occur within the warranty
period based on the date of sale. The standard warranty period is twelve (12)
months from start-up or eighteen (18) months from the date of shipment,
whichever occurs first, unless an extended warranty was offered in writing in
which case the extended warranty will take precedence. The cost of warranty will
be the most recent cost of direct materials, plus the cost of direct labor at
the wage rate of the employee assigned to the warranty project, plus an overhead
rate consistent with Buyer's most recent Operating Plan at the time the warranty
work occurs. The cost of warranty for materials returned to vendors will be the
cost of replacement less any credit received from the vendor.

                                    (B) Back charges by customers, clients or
subcontractors for work performed by others to complete a contract or sales
credits issued as a result of disputes are not considered warranty expense for
the purposes of Damages upon a breach of Section 4(u). Out-of-pocket costs for
the initial visit to a customer's site to inspect a product or installation to
determine if a warranty situation exists shall not be considered warranty
expense chargeable against the Escrow Account as Damages but subsequent service
visits to the same customer's site to reassess the defective product or
installation shall be considered warranty expense chargeable against the Escrow
Account as Damages.

                  (e) Indemnification Procedures. If a claim for indemnification
is made by any Party (the "Indemnitee") hereunder against another party (the
"Indemnifying Party"), the Indemnitee shall give written notice to the
Indemnifying Party as soon as practical after the Indemnitee becomes aware of
any fact, condition or event which may give rise to a claim for which
indemnification may be sought under this Section 7.

                           (i) In the event that any lawsuit or enforcement
action is filed against Indemnitee and Indemnitee seeks indemnification
hereunder, written notice thereof shall be given to the Indemnifying Party as
promptly as practicable (and in any event within fifteen (15) days after the
service of the citation or summons). After such notice, if the Indemnifying
Party shall acknowledge in writing to the Indemnitee that the Indemnifying Party

                                       36

<PAGE>



shall be obligated under the terms of its indemnity hereunder in connection with
such lawsuit or action, then the Indemnifying Party shall be entitled, if it so
elects, to take control of the defense and investigation of such lawsuit or
action and to employ and engage attorneys of its own choice to handle and defend
the same, at the Indemnifying Party's cost, risk and expense, provided that the
Indemnifying Party and its counsel shall proceed with diligence and in good
faith with respect thereto. The Indemnitee shall cooperate in all reasonable
respects with the Indemnifying Party and such attorney in the investigation,
trial and defense of such lawsuit or action and any appeal arising therefrom. If
the Indemnifying Party has acknowledged to the Indemnitee its obligation to
indemnify hereunder, the Indemnifying Party shall not settle such lawsuit or
enforcement action without the prior written consent of the Indemnitee. If the
Indemnifying Party has not so acknowledged its obligation, the Indemnitee shall
not settle such lawsuit or enforcement action without twenty (20) days' prior
notice to the Indemnifying Party. The provisions of this Section 7(e) shall be
applicable with respect to any claim, audit, examination, or assessment for
Taxes referenced in Section 4(k)(vii) and Section 7(a)(i)(B) above.

                           (ii) The Indemnitee shall not pay or satisfy any
obligation for an indemnified claim if it is advised in writing that such amount
is being contested in good faith by the Indemnifying Party who in fact actively
contests or defends the same. The Parties shall use their best efforts to
resolve equitably and expeditiously any dispute between them as to a Liability.

                  (f) Exclusive Remedy. The indemnification rights and remedies
set forth in this Section 7 shall be the sole and exclusive rights and remedies
of the parties hereto with respect to the matters referred to in this Section 7.

         8. Miscellaneous.

                  (a) Survival and Materiality. Each of the representations,
warranties and agreements of the Parties contained in this Agreement shall be
deemed material and shall survive the Closing and the consummation of the
transactions contemplated hereby regardless of any due diligence investigations
by the Parties prior to the Closing. All statements contained in any Exhibits,
Schedules or other agreements delivered by or on behalf of the Parties pursuant
hereto or in connection with the transactions contemplated hereby shall be
deemed material and shall constitute representations and, except to the extent
otherwise provided herein, warranties by the person making such statement.

                  (b) No Third Party Beneficiaries. This Agreement shall not
confer any rights or remedies upon any Person other than the Parties and their
respective successors and permitted assigns.

                  (c) Entire Agreement. This Agreement, together with the
Exhibits and Schedules to be delivered pursuant hereto, constitute the entire
agreement between the Parties and supersedes any prior understandings,

                                       37

<PAGE>



agreements, or representations by or between the Parties, written or oral,
(including without limitation any confidentiality agreement between the Parties
and that certain Letter of Intent executed by the Parties and SAC Sales Corp.
dated July 3, 1996).

                  (d) Succession and Assignment. This Agreement shall be binding
upon and inure to the benefit of the Parties named herein and their respective
successors and permitted assigns. No Party may assign either this Agreement or
any of its or his rights, interests, or obligations hereunder without the prior
written approval of the other Parties; provided, however, that Buyer may (i)
assign any or all of its rights and interests hereunder to one or more of its
Affiliates and (ii) designate one or more of its Affiliates to perform its
obligations hereunder (in any or all of which case Buyer nonetheless shall
remain responsible for the performance of all of its obligations hereunder).

                  (e) Counterparts. This Agreement may be executed in one or
more counterparts, each of which shall be deemed an original but all of which
together will constitute one and the same instrument.

                  (f) Headings. The section headings contained in this Agreement
are inserted for convenience only and shall not affect in any way the meaning or
interpretation of this Agreement.

                  (g) Notices. All notices, requests, demands, claims, and other
communications hereunder will be in writing. Any notice, request, demand, claim,

requested, postage prepaid, and addressed to the intended recipient as set forth

Any Party may send any notice, request, demand, claim, or other communication
hereunder to the intended recipient at the address set forth above using any
other means (including personal delivery, expedited courier, messenger service,
telecopy, telex, ordinary mail, or electronic mail), but no such notice,

Party may change the address to which notices, requests, demands, claims, and
other communications hereunder are to be delivered to such Party by giving the
other Parties notice in the manner herein set forth.

                  (h) Governing Law. This Agreement shall be governed by,
construed and interpreted in accordance with the domestic laws of the
Commonwealth of Pennsylvania and the Federal law of the United States of
America, where applicable, without giving effect to any choice or conflict of
law provision or rule (whether of the Commonwealth of Pennsylvania or any other
jurisdiction) that would cause the application of the laws of any jurisdiction
other than the Commonwealth of Pennsylvania.

<PAGE>



                  (i) Amendments and Waivers. No amendment of any provision of
this Agreement shall be valid unless the same shall be in writing and signed by
all the Parties. No waiver by any Party of any default, misrepresentation, or
breach of warranty or covenant hereunder, whether intentional or not, shall be
deemed to extend to any prior or subsequent default, misrepresentation, or
breach of warranty or covenant hereunder or affect in any way any rights arising
by virtue of any prior or subsequent such occurrence.

                  (j) Severability. Any term or provision of this Agreement that
is invalid or unenforceable in any situation in any jurisdiction shall not
affect the validity or enforceability of the remaining terms and provisions
hereof or the validity or enforceability of the offending term or provision in
any other situation or in any other jurisdiction.

                  (k) Expenses. Each of the Parties will bear its own costs and
expenses (including legal fees and expenses) incurred in connection with this
Agreement and the transactions contemplated hereby. Strobic agrees that it has
not paid any amount to any third party, and will not pay any amount to any third
party, with respect to any of the costs and expenses of Strobic and the Named
Stockholders (including any of their legal fees and expenses) in connection with
this Agreement or any of the transactions contemplated hereby.

                  (l) Construction. The Parties have participated jointly in the
negotiation and drafting of this Agreement. In the event an ambiguity or
question of intent or interpretation arises, this Agreement shall be construed
as if drafted jointly by the Parties and no presumption or burden of proof shall
arise favoring or disfavoring any Party by virtue of the authorship of any of
the provisions of this Agreement. Any reference to any federal, state, local, or
foreign statute or law shall be deemed also to refer to all rules and
regulations promulgated thereunder, unless the context requires otherwise. The
word "including" shall mean including without limitation. Nothing in the
Disclosure Schedule shall be deemed adequate to disclose an exception to a
representation or warranty made herein unless the Disclosure Schedule identifies
the exception with reasonable particularity and describes the relevant facts in
reasonable detail. Without limiting the generality of the foregoing, the mere
listing (or inclusion of a copy) of a document or other item shall not be deemed
adequate to disclose an exception to a representation or warranty made herein
(unless the representation or warranty has to do with the existence of the
document or other item itself). The Parties intend that each representation,
warranty, and covenant contained herein shall have independent significance. If
any Party has breached any representation, warranty, or covenant contained
herein in any respect, the fact that there exists another representation,
warranty, or covenant relating to the same subject matter (regardless of the
relative levels of specificity) which the Party has not breached shall not
detract from or mitigate the fact that the Party is in breach of the first
representation, warranty, or covenant.

                  (m) Incorporation of Exhibits and Schedules. The Exhibits and
Schedules identified in this Agreement are incorporated herein by reference
and made a part hereof.

                  (n) Specific Performance. Each of the Parties acknowledges and
agrees that the other Party would be damaged irreparably in the event any of

                                       40

<PAGE>



the provisions of this Agreement are not performed in accordance with their
specific terms or otherwise are breached. Accordingly, each of the Parties
agrees that the other Party shall be entitled to an injunction or injunctions to
prevent breaches of the provisions of this Agreement and to enforce specifically
this Agreement and the terms and provisions hereof in any action instituted in
any court of the United States or any state thereof having jurisdiction over the
Parties and the matter (subject to the provisions set forth in Section 11(p)
below), in addition to any other remedy to which it may be entitled, at law or
in equity.

                  (o) Arbitration. Except for the calculation of Damages
relating to or resulting from any Tax Liability or Tax Benefit as set forth in
Section 7(d), all claims, demands, disputes, controversies, differences or
misunderstandings between or among the Parties hereto shall be settled by
arbitration at Doylestown, Pennsylvania, in accordance with the American
Arbitration Association Rules then obtaining. Any determination rendered in such
proceeding shall be binding and conclusive upon the Parties hereto and judgment
thereon may be entered in any court having jurisdiction thereof. The Parties
hereto agree that arbitration shall be the sole and exclusive remedy of the
Parties with respect to any such matter for which arbitration is required
hereunder.

                  (p) Employee Matters. Buyer will, effective at the Closing,
hire all Strobic employees conditioned, as Buyer determines, to certain persons
executing a form of non-disclosure and/or non-compete agreement(s), initially at
the same rate of compensation (excepting Secrest, whose employment shall be
pursuant to a certain Employment Agreement with Buyer and Met-Pro), but subject
to adjustment as Buyer determines in its sole discretion subsequent to the
Closing. Nothing in this Section 11(q) or elsewhere in this Agreement is
intended to confer upon any Strobic employee any right to continued employment,
except as may be specified in any other separate agreement entered into between
Buyer and such employee. If in Met-Pro's sole discretion, any former Strobic
employee is subsequently hired by Met-Pro, any such person will be given credit
for service with Strobic for purposes of eligibility, vesting or length of
service requirements only, when such person becomes eligible for participation
under Met-Pro's Employee Benefit Plans as provided by the terms of such plans.

                  (q) Future Assurances. At any time and from time to time from
and after Closing, upon the request of any Party, Buyer, Met-Pro, and/or Named
Shareholders, as appropriate, will do, execute, acknowledge and deliver, or










                                       41

<PAGE>



cause to be delivered, all such further acts, deeds, bills of sale, assignments,
conveyances, powers of attorney and other documents as may be required to carry
out the provisions of this Agreement.

         IN WITNESS WHEREOF, the Parties hereto have executed, or caused their
duly authorized officers to execute, this Agreement on the date first above
written.

Met-Pro Corporation
160 Cassell Road
Harleysville, PA 19438        Re:  Registration Statement on Form S-3
                                   Under the Securities Act of 1933, as amended
                                   --------------------------------------------

Gentlemen:

In my capacity as counsel to Met-Pro corporation, a Delaware corporation, (the
"Company"), I have been asked to render this opinion in connection with a
Registration Statement on Form S-3 being filed contemporaneously herewith by the
Company with the Securities & Exchange Commission under the Securities Act of
1933, as amended (the "Registration Statement"), covering 195,920 shares of
Common Stock, par value $.10 per share, of the Company (the "Shares") delivered
on September 12, 1996, in connection with the acquisition of Strobic Air
Corporation ("Strobic").

In that connection, I have examined the Certificate of Incorporation, as
amended, the By-Laws, as amended, the Registration Statement, the Agreement and
Plan of Merger dated September 12, 1996, (the "Merger Agreement") pursuant to
which the Shares were delivered, corporate proceedings relating to the Shares
delivered and such other instruments and documents as I deemed relevant under
the circumstances.

In making these examinations, I have assumed the genuineness of all signatures
and the conformity of all copies furnished to me as original or photostatic
copies. I have also assumed that the corporate records furnished to me by the
Company include all corporate proceedings of the Company to date.
My investigations revealed the following facts:

The Shares were originally issued either for sufficient consideration or in
connection with various stock splits approved by the Board of Directors of the
Company. They were subsequently repurchased from time to time on the open market
by the Company pursuant to Stock Repurchase Plans and held in treasury. The
Shares were transferred on September 12, 1996 to the holders named in the
Registration Statement as Selling Stockholders in exchange for their Strobic
shares.

Based upon and subject to the foregoing, I am of the opinion that:

         1. The Company has been duly organized under the Delaware Corporation
Law and is a

validly subsisting corporation under the laws of the State of Delaware; and

         2. The Shares have been duly and validly authorized and issued and are
fully paid and nonassessable.

I consent to the use of this opinion as an exhibit to the Registration Statement
and to the use of my name under the caption "Legal Opinion" in the Prospectus
forming a part of the Registration Statement. I am the beneficial owner of
195,714 shares of Common Stock of the Company.

                                                              Very truly yours,



                                                              /s/Earl J. Wofsey

                    [LETTERHEAD OF MARGOLIS & COMPANY P.C.]
