            The following table sets forth certain data concerning total net
sales to customers by geographic area in the past three years:

                                          PERCENTAGE OF NET SALES
                                        FISCAL YEAR ENDED JANUARY 31,
                                   1998              1997              1996

                                 ==========================================


CUSTOMERS:

            Over the past three years, no single customer accounted for 10% or
more of the total net sales of the Company in any year.


COMPETITION:

            The Company experiences competition from a variety of sources with
respect to virtually all of its products. The Company knows of no single entity
that competes with it across the full range of its products and systems. The
lines of business in which the Company is engaged are highly competitive.
Competition in the markets served is based on a number of considerations, which
may include price, technology, applications experience, know-how, reputation,
product warranties, service and distribution.

            With respect to the Fluid Handling Equipment segment, specifically
the pump manufacturing operations, several companies, including Ingersoll
Dresser Pumps Corp., Goulds Pumps, Inc., and The Duriron Company, dominate the
industry with several smaller companies competing in selected product lines and
niche markets.

            With respect to the Pollution Control Systems and Allied Equipment
segment, there are numerous competitors of both comparable and larger size which
may have greater resources than the Company, but there are no companies that
dominate the market.

            The Company is unable to state with certainty its relative market
position in all aspects of its business.

RESEARCH AND DEVELOPMENT:

            The Company engages in research and development on an operational
basis. The research and development effort is not centralized due to the wide
range of products. Research is directed towards the development of new products
related to current product lines, and the improvement and enhancement of
existing products.

            The principal goals of the Company's research programs are
maintaining the Company as a technological leader in the production of pollution
control and allied equipment, and fluid handling equipment; developing new
products; and providing technological support to the manufacturing operations.

            Research and development expenses were $0.7 million in 1998, $0.7
million in 1997 and $0.6 million in 1996.


PATENTS AND TRADEMARKS:

            The Company maintains a small number of patents and trademarks. The
Company considers these items important to the business, although it considers
no individual item material to its business.


REGULATORY MATTERS:

            The Company is subject to environmental laws and regulations
concerning air emissions, discharges to water processing facilities, and the
generation, handling, storage and disposal of waste materials in all operations.
All of the Company's production and manufacturing facilities are controlled
under permits issued by federal, state and local regulatory agencies. The
Company believes it is presently in compliance with these laws and regulations.
Compliance with federal, state and local provisions relating to protection of
the environment has had no material effect upon capital expenditures, earnings
or the competitive position of the Company.


BACKLOG:

            Generally, the Company's customers are not subject to long-term
contracts, but to purchase orders accepted by the Company. The rate of booking
new orders varies from month to month. In addition, the orders have varying
delivery schedules, and the Company's backlog as of any particular date may not
be representative of actual revenues for any succeeding period. The dollar
amount of the Company's backlog of orders considered to be firm totalled
$6,143,284 and $6,017,795 as of January 31, 1998 and 1997, respectively.


RAW MATERIALS:

            The Company procures its raw materials and supplies from various
sources. The Company believes it could secure substitutes for the raw materials
and supplies should they become unavailable, but there are no assurances that
the substitutes would perform as well or be priced competitively. The Company
has not experienced difficulty in securing raw materials and supplies and does
not anticipate any difficulty in procurement in the coming year or foreseeable
future.


EMPLOYEES:

            As of January 31, 1998, the Company employed approximately 387
persons, of whom 184 were involved in manufacturing, and 203 were engaged in
administration, sales, engineering, supervision and clerical work. The Company
has had no work stoppages during the past 15 years and considers its employee
relations to be good.


FOREIGN OPERATIONS:

            Most of the Company's operations and assets are located in the
United States. The Company also owns a manufacturing operation in Heerenveen,
Holland through its wholly owned subsidiary, Mefiag B.V.

            Large export sales are made on the basis of confirmed irrevocable
letters of credit or time drafts to selected customers in U.S. dollars.
Therefore, the Company believes that currency fluctuation, and political and
economic instability do not constitute substantial risks to the business.

            For information concerning foreign net sales on a segment basis,
reference is made to the Consolidated Business Segment Data contained on page
18.

            During the fiscal year ended January 31, 1998, the Company sold an
idle manufacturing facility located in Bensalem, Pennsylvania in which it
formerly housed the Strobic Air operations which were consolidated into the
Met-Pro Corporation headquarters in Harleysville, Pennsylvania. In addition, the
Company sold the idle manufacturing facility in Las Piedras, Puerto Rico which
housed its wholly owned subsidiary, Mefiag of Puerto Rico, Inc. On January 31,
1997, this subsidiary was merged into the Company's Harleysville, Pennsylvania
manufacturing operations to maximize capacity and improve economies of scale.

ITEM 3. LEGAL PROCEEDINGS:

            Subsequent to January 31, 1997, the Company was served with a
Complaint filed against the Company and several other corporations and
individuals in the United States District Court for the Eastern District of
Pennsylvania. The plaintiff, F. P. Woll, Inc., is the present owner of land and
building ("Site") in Lansdale, Pennsylvania which was occupied by the Company
and its predecessor for approximately 20 years prior to 1976. The other
defendants identified in the Complaint are entities which owned or occupied the
Site or neighboring properties at various times, or which insured entities that
owned or occupied the Site. The Complaint alleges that the plaintiff has been
ordered by the United States Environmental Protection Agency (the "EPA") to take
remedial action with respect to petroleum contamination allegedly detected on
the Site. The Complaint seeks declaratory relief and monetary damages under
federal and state statutes and the common law to recover from the defendants all
or some portion of the expenses which the plaintiff has incurred or may incur in
connection with the condition of the Site. The Company is vigorously defending
against the Complaint. The Company has answered the Complaint and is proceeding
with its investigation and discovery of plaintiff's allegations. Because
discovery has not yet been completed, it is not possible to assess the strength
of the plaintiff's claims or the nature of the Company's defense.

            There are no other material pending legal proceedings to which the
Company or any of its wholly owned subsidiaries is a party as of the date of
this Annual Report.


ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS:

            No matters were submitted to a vote of security holders during the
fourth quarter of the fiscal year ended January 31, 1998.

            FYE 1998 vs FYE 1997:

            Net sales for the year ended January 31, 1998 were $62.4 million, a
new record, exceeding net sales for the year ended January 31, 1997 by $1.5
million, an increase of 2.5%. This is the fifth consecutive year of record net
sales. Sales in the Pollution Control Systems and Allied Equipment segment were
$1.9 million or 6.0% higher than the prior fiscal year due to the acquisition of
Strobic Air, effective as of July 31, 1996, combined with higher demand
primarily for our fume and odor control equipment. Sales in the Fluid Handling
Equipment segment were $0.4 million or 1.3% lower than the prior year.

            Foreign sales increased to $8.8 million for the fiscal year ended
January 31, 1998 which is a 16.1% increase over the prior year. This increase
was due to higher sales in the Middle East region, Pacific Rim, South America
and Caribbean Market. Foreign sales increased 18.8% in the Fluid Handling
Equipment segment versus the prior fiscal year, while the Pollution Control
Systems and Allied Equipment segment increased 0.7% versus the prior fiscal
year.

            Net income of $7.1 million for the fiscal year ended January 31,
1998 was $1.0 million or 16.7% above the earnings level of the prior year. This
is the fifth consecutive year of increased earnings.

            The gross margin for the fiscal year ended January 31, 1998
increased to 36.2% versus 34.0% for the prior fiscal year. The improvement in
gross margin can be attributed to a combination of factors including product
mix, production efficiencies and the out-sourcing of the Systems Division's
manufacturing operations.

            Selling expense increased approximately $0.5 million or 9.8% over
the prior fiscal year. The Strobic Air acquisition accounted for $0.3 million of
the increase, combined with increased staffing and marketing efforts in existing
operations to position the Company for future growth. Selling expense as a
percentage of net sales was 8.5% for the fiscal year ended January 31, 1998,
compared to 8.0% for the prior fiscal year.

            General and administrative expense was $6.6 million for the fiscal
year ended January 31, 1998 compared to $6.7 million in the prior fiscal year.
Our continued focus on cost controls enables us to decrease overall general and
administrative expenses. General and administrative expense as a percentage of
net sales was 10.5% for the fiscal year ended January 31, 1998 compared to 11.0%
for the prior fiscal year.

            Other income of $1.0 million for the fiscal year ended January 31,
1998 consisted primarily of interest income earned on short-term investments and
a $0.2 million net gain on the disposal of certain properties. Other income of
$0.9 million at January 31, 1997 consisted of interest income on short-term
investments and a $0.4 million net gain on the disposal of certain properties.

            The effective tax rate for the fiscal year ended January 31, 1998
was 39.0% compared to 39.5% for the prior year. The change in the effective tax
rate had virtually no effect on earnings per share for the fiscal year ended
January 31, 1998.

            FYE 1997 vs FYE 1996:

            Net sales for the year ended January 31, 1997 were $60.9 million, a
new record, exceeding net sales for the year ended January 31, 1996 by $6.8
million, an increase of 12.6%. This is the fourth consecutive year that net
sales have achieved a new record. Sales in the Pollution Control Systems and
Allied Equipment segment were $3.5 million or 12.4% higher than the prior fiscal
year due to the acquisition of Strobic Air, effective as of July 31, 1996,
coupled with higher demand primarily for our fume and odor control equipment.
Sales in the Fluid Handling Equipment segment were $3.3 million or 12.7% higher
compared to the prior year due primarily to increased demand for our specialty
pump equipment.

            Foreign sales increased to $7.5 million for the fiscal year ended
January 31, 1997 which is a 12.7% increase over the prior year. This increase
was due to higher sales in the Middle East region, Pacific Rim and the European
Common Market. Foreign sales increased 16.5% in the Fluid Handling segment
versus the prior fiscal year, while the Pollution Control Systems and Allied
Equipment segment were flat versus the prior fiscal year due to the timing of
fume and odor control orders.

            Net income of $6.1 million for the fiscal year ended January 31,
1997 was $1.2 million or 24.6% above the earnings level of the prior year. This
is the fourth consecutive year of increased earnings.

            The gross margin was 34.0% for the fiscal year ended January 31,
1997, equal to the prior year. The consistent gross margin is related to higher
sales volume and product mix in both business segments, and includes $0.3
million of costs associated with the relocation of the Puerto Rico operations
and the out-sourcing of the Systems Division's manufacturing operations.

            Selling expense increased approximately $0.4 million or 8.1% over
the prior fiscal year. The Strobic Air acquisition accounted for $0.1 million of
the increase, combined with increased staffing and marketing efforts in existing
operations to position the Company for future growth. Selling expense as a
percentage of net sales was 8.0% for the fiscal year ended January 31, 1997,
virtually equal to the prior fiscal year.

            General and administrative expense was $6.7 million for the fiscal
year ended January 31, 1997 compared to $6.3 million in the prior fiscal year.
The $0.4 million increase can be attributed entirely to the acquisition of
Strobic Air. General and administrative expense as a percentage of net sales was
11.0% for the fiscal year ended January 31, 1997 compared to 11.6% for the prior
fiscal year.

            Other income of $0.9 million for the fiscal year ended January 31,
1997 consisted primarily of interest income earned on short-term investments and
a $0.4 million net gain on the disposal of certain properties. Other income of
$0.6 million at January 31, 1996 consisted primarily of interest income on
short-term investments.

            The effective tax rate for the fiscal year ended January 31, 1997
was 39.5% compared to 40.5% for the prior year. Earnings per share for the
fiscal year ended January 31, 1997 increased approximately $.01 as a result of
the decline in the effective tax rate compared to the prior year.


LIQUIDITY:

            Cash and cash equivalents were $11.3 million on January 31, 1998, an
increase of $2.2 million over the previous year. The improvement is the result
of cash flows generated from operations combined with the proceeds received from
the sale of idle facilities.

            Accounts receivable were $10.7 million at January 31, 1998, an
increase of $0.1 million compared to the prior year. The size of orders, the
timing of shipments to meet customer requirements and retainage on contracts,
combined with increased sales volume, in the Pollution Control and Allied
Equipment segment, will influence accounts receivable balances at any point in
time.

            Inventories totalled $12.2 million at January 31, 1998, an increase
of $1.6 million compared to the prior year. Inventory balances will fluctuate
depending upon the size and timing of orders and market demand especially when
major systems and contracts are involved.

            Current liabilities decreased from $11.4 million at January 31, 1997
to $11.3 million at January 31, 1998 or $0.1 million.

            The Company has consistently maintained a high current ratio and has
not utilized lines of credit totalling $5.0 million which are available for
working capital purposes. The current ratio was 3.2 at January 31, 1998 versus a
ratio of 2.8 at January 31, 1997.

CAPITAL RESOURCES AND REQUIREMENTS:

            Cash flows provided by operating activities during the fiscal year
ended January 31, 1998 amounted to $7.4 million compared to $7.2 million during
the prior fiscal year. The increase of $0.2 million can be attributed to higher
operating profits in both business segments, customers' advances on projects in
progress, offset by higher inventory balances and the timing of the payment of
accounts payable.

            Cash flows used in investing activities during the fiscal year ended
January 31, 1998 amounted to $0.1 million compared to $3.8 million during the
fiscal year ended January 31, 1997. The Company's investing activities for the
fiscal year ended January 31, 1998 represent the acquisition of property and
equipment in the combined operations, offset by proceeds received from the sale
of property and equipment associated with Strobic Air operations which were
consolidated with existing facilities in Harleysville, Pennsylvania, and the
sale of an idle manufacturing facility in Las Piedras, Puerto Rico. The Company
continues to invest in machinery and equipment, tooling, patterns and molds to
improve efficiency and maintain our position as leaders in the markets in which
we serve.

            Financing activities during the fiscal year ended January 31, 1998
utilized $5.1 million of available resources compared to $1.7 million during the
prior fiscal year.

            The Company paid $1.6 million of scheduled long-term debt during the
current fiscal year. The long-term debt to equity ratio at January 31, 1998 was
5.1% compared to 9.1% at January 31, 1997.

            A total of 84,337 stock options were exercised during the year ended
January 31, 1998 which provided cash proceeds of approximately $0.5 million.

            The Company continued to repurchase shares outstanding on the open
market at prevailing prices under the stock buyback program authorized on
October 11, 1996. The Board of Directors also authorized one stock buyback
program totalling 150,000 shares during the fiscal year ended January 31, 1998.
The Company repurchased 134,300 shares at a cost of approximately $2.1 million
under the combined programs during the year ended January 31, 1998.

            The Board of Directors also declared a cash dividend of $.27 per
share which was paid on April 25, 1997 to stockholders of record April 11, 1997.
This represented a 22.7% increase in the dividend payout rate, amounting to $1.9
million or 31.4% of prior year earnings.

            As part of our commitment to the future, the Company expended $0.7
million on research and development for each of the fiscal years ended January
31, 1998 and 1997.

            The Company will continue to invest in new product development to
maintain and enhance our market position as leaders in the markets in which we
participate. Capital expenditures will be made to support operations and expand
our capacity to meet market demands. The Company intends to finance capital
expenditures in the coming year through cash flows from operations and will
secure third party financing, when deemed appropriate.


RECENT ACCOUNTING PRONOUNCEMENTS:

            In February 1997, the Financial Accounting Standards Board (the
"FASB") issued Statement of Financial Accounting Standards ("SFAS") No. 128,
"Earnings Per Share". SFAS No. 128 simplifies the standards for computing
earnings per share and is effective for financial statements for both interim
and annual periods ending after December 15, 1997. Basic earnings per share are
computed based on the weighted average number of common shares actually
outstanding during the year. Met-Pro implemented SFAS No. 128 in the financial
statements for the fiscal year ended January 31, 1998.

            In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income". SFAS No. 130 establishes standards for reporting and display of
comprehensive income and its components in the financial statements. SFAS No.
130 is effective for fiscal years beginning after December 15, 1997.
Reclassification of financial statements for earlier periods provided for
comparative purposes is required. Met-Pro is in the process of determining its
preferred format. The adoption of SFAS No. 130 will have no impact on Met-Pro's
consolidated results of operations, financial position or cash flows.

            In June 1997, the FASB issued SFAS No. 131, "Disclosures about
Segments of an Enterprise and Related Information". SFAS No. 131 establishes
standards for the way public business enterprises report information about
segments in the annual financial statements and requires that those enterprises
report selected information about operating segments in interim financial
reports issued to shareholders. It also establishes standards for related
disclosures about products and services, geographic areas and major customers.
SFAS No. 131 is effective for financial statements for fiscal years beginning
after December 15, 1997. Financial statement disclosures for prior periods are
required to be restated. Met-Pro is in the process of evaluating the disclosure
requirements. The adoption of SFAS No. 131 will have no impact on Met-Pro's
consolidated results of operations, financial position or cash flows.

                                       12

<PAGE>

            In February 1998, the FASB issued SFAS No. 132, "Employer's
Disclosures about Pensions and Other Postretirement Benefits". SFAS No. 132
establishes standards for the disclosures of pension and other postretirement
benefit plans. It does not change the measurement and recognition standards for
those plans, but does revise and replace the prior disclosure requirements. SFAS
No. 132 is effective for fiscal years beginning after December 15, 1997.
Financial statement disclosures for prior periods are required to be restated.
Met-Pro is in the process of evaluating the disclosure requirements. The
adoption of SFAS No. 132 will have no impact on Met-Pro's consolidated results
of operations, financial position or cash flows.


YEAR 2000 COMPLIANCE:

            During the fiscal year ended January 31, 1998, the Company began to
modify its computer software to correctly process dates for the Year 2000. The
Company presently believes that the modifications to its existing software are
complete. Although the Company does not expect that it will incur material sums
prior to the year 2000 in connection with computer software modifications
required in connection therewith, no assurances can be given as to this, nor as
to whether the Company will not be adversely affected by Year 2000 compliance
problems.


CAUTIONARY STATEMENT REGARDING FORWARD LOOKING STATEMENTS:

            As a cautionary note to investors, the Company and its
representatives may make oral or written statements from time to time that are
"forward-looking statements". This would include information concerning possible
or assumed future activities, plans, results of operations of the Company and
statements preceded by, followed by or that include the words "believes",
"expects", "anticipates", "intends" or similar expressions. For those
statements, the Company claims the protection of the safe harbor for forward-
looking statements contained in the Private Securities Litigation Reform Act 
of 1995.

            There are a number of important factors which could cause actual
results to differ materially from those anticipated. The Company believes that
its future operating results will continue to be subject to quarterly variations
based upon a wide variety of factors, including the cyclical nature of both the
business segments and the markets addressed by the Company's products, price
erosion, competitive factors, the timing of new product introductions, changes
in product mix, the availability and extent of utilization of manufacturing
capacity, product obsolescence and the ability to develop and implement new
technologies. The Company's operating results could also be impacted by sudden
fluctuations in customer requirements, currency exchange rate fluctuations and
other economic conditions affecting customer demand and the cost of operations
in one or more of the global markets in which the Company does business. As a
participant in the pollution control and fluid handling industries, the Company
operates in a rapidly changing and highly competitive environment. The Company
sells both custom products to customers, and industrial products; accordingly,
changes in the conditions or composition of any of the Company's customers may
have an impact on the Company. While the Company cannot predict what effect
these various factors may have on its financial results, the aggregate effect of
these and other factors could result in volatility in the Company's future
performance and stock price.

                          INDEPENDENT AUDITOR'S REPORT


To the Board of Directors and Stockholders
Met-Pro Corporation and its Wholly Owned Subsidiaries
Harleysville, Pennsylvania

We have audited the accompanying consolidated balance sheet of Met-Pro
Corporation and its wholly owned subsidiaries as of January 31, 1998 and 1997,
and the related consolidated statements of operations, stockholders' equity, and
cash flows for each of the three years in the period ended January 31, 1998.
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 audits.

We conducted our audits 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 audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Met-Pro Corporation
and its wholly owned subsidiaries as of January 31, 1998 and 1997 and the
results of their operations and their cash flows for each of the three years in
the period ended January 31, 1998 in conformity with generally accepted
accounting principles.

                               MET-PRO CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
               FOR THE YEARS ENDED JANUARY 31, 1998, 1997 AND 1996


NOTE 1: NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

        NATURE OF OPERATIONS:

        The Company manufactures and sells pollution control and allied
        equipment for purification of air and liquids, and fluid handling
        equipment for corrosive, abrasive and high temperature liquids.

        BASIS OF PRESENTATION:

        The consolidated financial statements include the accounts of Met-Pro
        Corporation ("Met-Pro" or the "Company") and its wholly owned
        subsidiaries, Mefiag B.V. and Strobic Air Corporation ("Strobic Air").
        Significant intercompany accounts and transactions have been eliminated.
        Accounts denominated in foreign currencies have been remeasured into the
        functional currency in accordance with Statement of Financial Accounting
        Standards ("SFAS") No. 52, "Foreign Currency Translation," using the
        U.S. dollar as the functional currency.

        The preparation of financial statements in conformity with generally
        accepted accounting principles requires management to make estimates and
        assumptions that affect the reported amounts of assets and liabilities
        and disclosure of contingent assets and liabilities at the date of the
        financial statements and the reported amounts of revenues and expenses
        during the reporting period. Actual results could differ from those
        estimates.

        INVENTORIES:

        Inventories generally are stated at the lower of cost (principally
        first-in, first-out) or market except for the inventory at the Dean Pump
        Division which is determined on the last-in, first-out basis (see 
        Note 5).

        PROPERTY, PLANT AND EQUIPMENT:

        Property, plant and equipment are stated at cost. Depreciation is
        computed principally by the straight-line method over estimated useful
        lives. Expenditures for maintenance and repairs are charged to expense
        as incurred. Renewals and betterments are capitalized (see Note 6).

        COSTS IN EXCESS OF NET ASSETS OF BUSINESSES ACQUIRED:

        Costs in excess of net assets of businesses acquired prior to November
        1, 1970, totalling $582,513, are not being amortized because management
        believes that there has been no impairment in value. Costs in excess of
        net assets of businesses acquired subsequent to October 31, 1970,
        totalling $6,616,402, are being amortized over 40 years. The Company
        monitors the recoverability of goodwill using a fair value approach.

        REVENUE RECOGNITION:

        Revenues are recognized when products are shipped.

        ADVERTISING:

        Advertising costs are charged to operations in the year incurred and
        were $1,111,724, $809,476 and $767,507 for the years ended January 31,
        1998, 1997 and 1996, respectively.

        RESEARCH AND DEVELOPMENT:

        Research and development costs are charged to operations in the year
        incurred and were $726,278, $670,336 and $584,191 for the years ended
        January 31, 1998, 1997 and 1996, respectively.

                     NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
          FOR THE YEARS ENDED JANUARY 31, 1998, 1997 AND 1996 - (CONTINUED)


        EARNINGS PER SHARE:

        During the year ended January 31, 1998, the Company adopted SFAS No.
        128, "Earnings Per Share". SFAS 128 establishes standards for computing
        basic and diluted earnings per share and is effective for periods ending
        after December 15, 1997. Basic earnings per share are computed based on
        the weighted average number of common shares actually outstanding during
        each year. The weighted average number of shares outstanding was
        7,053,071, 6,989,717 and 6,999,408 during each of the years ended in
        1998, 1997 and 1996, respectively.

        Diluted earnings per share are computed based on the weighted average
        number of shares actually outstanding plus all dilutive potential common
        shares outstanding (stock options) during each year. The weighted
        average number of common shares outstanding was 7,144,931, 7,096,214 and
        7,051,527 during each of the years ended in 1998, 1997 and 1996,
        respectively.

        STOCK SPLITS:

        On May 12, 1995, the Company issued 1,565,803 shares of Common Stock in
        connection with a 3-for-2 stock split, and on July 8, 1996, the Company
        issued 2,379,197 shares of Common Stock in connection with a 3-for-2
        stock split. Both stock splits were in the form of a 50% stock dividend.
        Per share figures and other information included in the financial
        statements and notes are based on the increased number of shares after
        giving affect to the stock splits.

        CONCENTRATIONS OF CREDIT RISK:

        The Company believes concentrations of credit risk are limited due to
        the number of customers, and dispersion among the business segments and
        geographic areas. The Company had no significant concentrations of
        credit risk as of January 31, 1998 and 1997.

        SUPPLEMENTAL CASH FLOW INFORMATION:

                                             1998           1997         1996
        ------------------------------------------------------------------------
        Cash paid during the year for:
          Interest                          $314,735       $228,841     $258,297
        ------------------------------------------------------------------------
          Income taxes                    $4,530,301     $4,039,248   $3,148,038
        ------------------------------------------------------------------------


        CHANGES IN ACCOUNTING POLICIES:

        In June 1997, the Financial Accounting Standards Board (the "FASB")
        issued SFAS No. 130, "Reporting Comprehensive Income" and SFAS No. 131,
        "Disclosures about Segments of an Enterprise and Related Information".
        In February 1998, the FASB also issued SFAS No. 132, "Employer's
        Disclosures about Pensions and Other Postretirement Benefits". These
        pronouncements are effective for fiscal years beginning after December
        15, 1997, and thus do not effect any of the financial statements
        reported on herein, but will become effective for our fiscal year
        beginning February 1, 1998. The adoption of these pronouncements will
        have no impact on Met-Pro's consolidated results of operations,
        financial position or cash flows, but upon adoption will require
        disclosures for prior periods to be restated.

NOTE 2: ACQUISITION OF BUSINESS

        Effective July 31, 1996, the Company, pursuant to an Agreement and Plan
        of Merger, acquired the Common Stock of Strobic Air for a purchase price
        of approximately $5,000,000. The acquisition was accounted for as a
        purchase transaction. Strobic Air designs, manufactures and markets the
        patented Tri-Stack(R) direct drive mixed flow exhaust fans which are 
        state-of-the-art design.

        The acquisition was completed by issuing Common Stock from the treasury
        valued at $2,400,020 (195,920 shares), a cash payment of $2,150,000, a
        promissory note payable for $250,000, plus acquisition costs. As part of
        the transaction, the Company entered into a non-compete agreement in the
        amount of $1,000,000 having a four-year term. Bank loans totalling
        $3,500,000, consisting of two $1,750,000 notes, one with a floating
        interest rate and one with a fixed interest rate (see Note 7), were used
        to finance the purchase. Goodwill totalling $3,914,602 was acquired and
        will be amortized over 40 years.

        On December 31, 1996, the Securities and Exchange Commission declared
        effective the Company's Registration Statement on Form S-3 pursuant to
        which the Company registered an aggregate of 195,920 shares of Common
        Stock issued to the former stockholders of Strobic Air in connection
        with the acquisition. The shares registered may be sold pursuant to the
        plan of distribution described therein. An aggregate of 193,544 of such
        shares were subject, through December 11, 1997, to certain contractual
        restrictions.

        The following unaudited pro forma summary presents the consolidated
        results of operations for the year ended January 31, 1997 as if the
        Company had acquired Strobic Air on February 1, 1996:

        (approximating market) and amounted to $10,652,199 and $8,495,100,
        respectively. Short-term investments consist principally of commercial
        paper maturing within three months and money market funds, both of which
        are considered to be cash equivalents. The Company evaluates the
        creditworthiness of the financial institutions and financial instruments
        in which it invests.

        Carrying amount                  3,684,011                  5,268,506

        Valuations for long-term debt are determined based on borrowing rates
        currently available to the Company for loans with similar terms and
        maturities.

        The Company's financial instruments are not held for trading purposes.

        INCENTIVE STOCK OPTION PLANS:

        The Company accounts for employee stock options in accordance with
        APB No. 25, "Accounting for Stock Issued to Employees" and related
        Interpretations. The pro forma disclosures required by SFAS No. 123,
        "Accounting for Stock-Based Compensation", are not presented since the
        impact on the Company's financial statements for the periods presented
        is de minimis.

        In 1987 ("1987 Plan"), the Company adopted an incentive stock option
        plan under which 100,000 shares (354,375 after stock splits and
        dividends) of the Company's Common Stock were reserved for employees as
        selected by the Board of Directors. Effective April 9, 1997, the 1987
        Plan terminated and the remaining shares available for grant expired.
        At the Company's annual meeting held June 3, 1992, a resolution for an
        additional 100,000 shares (225,000 after stock splits and dividends),
        as adopted by the Board of Directors on October 10, 1991 ("1992 Plan"),
        was approved. During the Company's annual meeting held June 4, 1997, a
        similar resolution for an additional 350,000 shares, as adopted by the
        Board of Directors on February 24, 1997 ("1997 Plan"), was approved.
        Each of the Plans provides for anti-dilution provisions.
