                 6 1/2% Convertible Subordinated Notes Due 2003
                  Interest Payable on March 1 and September 1
 
     The Notes offered hereby are convertible into Common Shares, without par
value (the "Common Shares"), of Robbins & Myers, Inc. (the "Company") at any
time prior to maturity, unless previously redeemed, at a conversion price of
$27.25 per share, subject to adjustment in certain events. The Common Shares are
traded on The Nasdaq Stock Market's National Market (the "Nasdaq National
Market") under the symbol "ROBN." On September 18, 1996, the last reported sale
price of the Common Shares on the Nasdaq National Market was $22.375 per share.
See "Price Range of Common Shares and Dividends."
 
     The Notes will mature on September 1, 2003. The Notes are redeemable, in
whole or in part, at the option of the Company at any time on or after September
1, 1999, at the redemption prices set forth herein, plus accrued and unpaid
interest. Upon a Change in Control (as defined), each holder of Notes will have
the right, subject to certain conditions and restrictions, to require the
Company to repurchase any or all outstanding Notes owned by such holder at 100%
of the principal amount thereof, plus accrued and unpaid interest.
 
     The Notes will be unsecured and subordinated to all present and future
Senior Indebtedness (as defined) of the Company. At September 18, 1996, after
giving effect to this offering and the application of the net proceeds
therefrom, Senior Indebtedness would have been approximately $17,606,000. See
"Use of Proceeds." At August 31, 1996, liabilities (including trade payables but
excluding inter-company liabilities) of the Company's subsidiaries, to which the
Notes are effectively subordinated, were approximately $93,856,000. See
"Description of the Notes."
 
THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
 EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE COMMISSION
   OR ANY STATE SECURITIES COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF
     THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL
     OFFENSE.

                               PROSPECTUS SUMMARY
 
     The following summary is qualified in its entirety by reference to the more
detailed information and financial statements, including the notes thereto,
appearing elsewhere, or incorporated by reference, in this Prospectus. Fiscal
year references refer to years ending August 31. Unless otherwise indicated, or
the context otherwise requires, all information in this Prospectus (i) is based
on the assumption that the Underwriters' over-allotment option is not exercised,
and (ii) gives effect to the 2-for-1 Common Share stock split effective July 31,
1996 (the "Stock Split").
 
                                  THE COMPANY
 
     The Company designs, manufactures and markets on a global basis
high-performance, specialized fluids management products for the process
industries. The Company's four product lines consist of glass-lined storage and
reactor vessels (38% of fiscal 1995 sales), progressing cavity products (30%),
mixing and turbine agitation equipment (22%), and related products such as
engineered systems, fluoropolymer products and valves (10%). The Company's
customers include the specialty chemicals, pharmaceuticals, oil and gas
recovery, wastewater treatment, pulp and paper, and food and beverage
industries.
 
     The Company has achieved leading market shares in each of its main product
lines: the Company believes that it is first worldwide in glass-lined storage
and reactor vessels, first in North America in progressing cavity products and
second worldwide in mixing and turbine agitation equipment. The Company also
believes that its principal brand names--Pfaudler(R), Moyno(R), and
Chemineer(R)--are well-recognized in the marketplace and are associated with
high performance, innovation and quality as well as with extensive customer
support, including product application engineering, state-of-the-art customer
test facilities and strong aftermarket capabilities.
 
     Since February 1992, the Company has completed eight acquisitions as part
of a strategy to leverage its fluids management expertise, its leadership in
progressing cavity technology, and its operating capabilities into a portfolio
of highly-engineered, fluids management products and services. The most
significant of these acquisitions occurred in June 1994 when the Company
acquired its Pfaudler(R), Chemineer(R) and Edlon(R) business units. These
acquisitions more than tripled the sales of the Company and provided leading
worldwide positions in two core product lines.
 
     The Company seeks to balance its mix of products and services and maintain
overall stability in its operating results principally through increased levels
of higher margin aftermarket sales, increased international presence with
manufacturing facilities in ten countries and end market diversification. In
fiscal 1995, aftermarket sales to the Company's customers as well as customers
of its competitors accounted for approximately 38% of total sales, international
sales accounted for approximately 45% of total sales and at least 5% of total
sales were derived from each of its five primary end markets.
 
     The Company has used its competitive strengths to achieve substantial
growth over the past several years. From fiscal 1991 through fiscal 1995, the
Company's sales and income before interest and taxes increased at a compound
annual rate of 40.1% and 31.6%, respectively, and for the nine months ended May
31, 1996, the Company's sales and income before interest and taxes increased
16.3% and 33.2%, respectively, as compared to the nine months ended May 31, 1995
(comparative figures are before the write-off of the Company's investment in
Hazleton Environmental in the third quarter of fiscal 1995).
 
     The Company seeks to continue to grow by (i) capitalizing on the inherent
growth of its end markets, particularly high-growth markets such as oil and gas
recovery, pharmaceuticals and food additives and supplements, which collectively
account for over 40% of the Company's sales; (ii) exploiting opportunities for
industry consolidation within existing markets, specifically the highly
fragmented positive displacement pump and industrial mixer industries; (iii)
expanding geographically, both internally and through acquisitions, into
high-growth emerging markets such as Asia/Pacific Rim and South America; and
(iv) establishing new product lines through acquisitions of related fluids
management businesses such as valves, filters and grinders.

(1) Results for Pfaudler(R), Chemineer(R), and Edlon(R), which were acquired on
    June 30, 1994, are included for two months in fiscal 1994 and 12 months in
    fiscal 1995.
 
(2) Includes restructuring charges of $950 in 1993 and $2,551 in 1994 and the
    write-off of the Company's investment in Hazleton Environmental of $1,612 in
    1995 and in the nine months ended May 31, 1995. See "Selected Consolidated
    Financial Data."
 
(3) Includes after-tax (charges) of $(3,658), $(.36) per share, in 1991 for
    discontinued operations and $(8,018), $(.76) per share, in 1993 for
    cumulative effect of accounting changes and an after-tax gain of $1,332,
    $.12 per share, in 1995 and of $1,332, $.13 per share, in the nine months
    ended May 31, 1995 for early extinguishment of debt.
 
(4) EBITDA represents earnings before interest income and interest expense,
    income taxes, depreciation and amortization (including amortization of debt
    discount). EBITDA is presented because it may be used as one indicator of a
    company's ability to service debt. The Company believes that EBITDA, while
    providing useful information, should not be considered in isolation or as a
    substitute for net income as an indicator of operating performance or as an
    alternative to cash flow as a measure of liquidity, in each case determined
    in accordance with generally accepted accounting principles.
 
(5) The ratio of earnings to fixed charges has been computed by dividing income
    from continuing operations before income taxes plus fixed charges (excluding
    capitalized interest expense) by fixed charges. Fixed charges consist of
    interest and debt expense and an appropriate portion of rentals.
 
(6) Calculated by dividing income before special items by average shareholders'
    equity and annualized for the nine month periods.
 
(7) Gives effect to the repurchase of the Repurchased Obligations, the issuance
    and sale of the Notes by the Company and the anticipated use of the
    estimated net proceeds therefrom as described in "Use of Proceeds."
 
(8) Capitalization consists of long-term debt and shareholders' equity.

                                USE OF PROCEEDS
 
     The net proceeds to the Company from the sale of the Notes are estimated to
be approximately $57.95 million after deducting underwriting discounts and
commissions and estimated expenses of the offering ($62.80 million if the
Underwriters' over-allotment option is exercised in full). The Company intends
to use such net proceeds to repay certain outstanding bank indebtedness,
including indebtedness which the Company drew under its revolving credit
facility in August 1996 in order to repurchase for approximately $24.1 million
and $.8 million, respectively, the remaining $25 million in principal amount of
senior subordinated notes and remaining stock appreciation rights (collectively,
the "Repurchased Obligations") which were issued by the Company in 1994 in
connection with the acquisition by the Company of its Pfaudler(R), Chemineer(R)
and Edlon(R) business units.
 
     At September 18, 1996, the outstanding indebtedness under the Company's
bank credit agreement was comprised of a $34.3 million term loan and $36.0
million under its revolving credit facility. The principal of the term loan is
payable in quarterly installments commencing September 1, 1997 and continuing
through 2001. Interest rates on both the term loan and revolving credit facility
are, at the Company's option, based upon either prime rates or a formula tied to
LIBOR rates. The effective annual interest rate on the loans was 7.68% at
September 18, 1996.
 
                                 CAPITALIZATION
 
     The following table sets forth the capitalization of the Company at May 31,
1996 and as adjusted to reflect the repurchase of the Repurchased Obligations,
the issuance and sale of the Notes by the Company and the application of the
estimated net proceeds therefrom (assuming that the Underwriters' over-allotment
option is not exercised).

(4) EBITDA represents earnings before interest income and interest expense,
    income taxes, depreciation and amortization (including amortization of debt
    discount). EBITDA is presented because it may be used as one indicator of a
    company's ability to service debt. The Company believes that EBITDA, while
    providing useful information, should not be considered in isolation or as a
    substitute for net income as an indicator of operating performance or as an
    alternative to cash flow as a measure of liquidity, in each case determined
    in accordance with generally accepted accounting principles.
 
(5) The ratio of earnings to fixed charges has been computed by dividing income
    from continuing operations before income taxes plus fixed charges (excluding
    capitalized interest expense) by fixed charges. Fixed charges consist of
    interest and debt expense and an appropriate portion of rentals.
 
(6) Calculated by dividing income before special items by average shareholders'
    equity and annualized for the nine month periods.
 
(7) Capitalization consists of long-term debt and shareholders' equity.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
     Since May 31, 1994, the Company has completed six acquisitions that have
significantly changed its business and financial profile. As a result of the
acquisitions, critical elements of the Company's strategy to expand its
capabilities to serve the fluids management needs of its customers on a global
basis were accomplished. The results of the most significant of the acquired
companies -- Pfaudler(R), Chemineer(R) and Edlon(R)-- are included in the
Company's results for twelve months in 1995 and for two months in 1994, which
significantly impact year to year comparisons. The nine month periods ended May
31, 1995 and 1996 include comparable operations.
 
     The acquisitions of Pfaudler(R), Chemineer(R) and Edlon(R) more than
tripled the Company's total sales and increased its international sales to
approximately 45% of consolidated sales. Profitability of the non-U.S. business
units of the Company was less than domestic business units both before and after
the acquisitions. Operating margins for the international businesses increased
to 9.7% for the nine months ended May 31, 1996 from 7.4% for the nine months
ended May 31, 1995. The improvements were the result of improved market
conditions and implementation by the Company of ongoing cost reduction programs
in its international operations.
 
     The Company seeks to balance its mix of products and services and maintain
overall stability in its operating results principally through increased levels
of aftermarket sales, increased international sales and end market
diversification. In fiscal 1995, aftermarket sales accounted for approximately
38% of total sales, international sales accounted for approximately 45% of total
sales and at least 5% of total sales were derived from each of the specialty
chemicals, pharmaceuticals, oil and gas recovery, wastewater treatment and pulp
and paper industries.

     NINE MONTHS ENDED MAY 31, 1996.  Net income of $14.2 million was 47.7%
higher than in the first nine months of 1995. Earnings per share of $1.28, fully
diluted, increased 42.2% from the first nine months of 1995. These increases
were primarily the result of higher volume and profit improvement programs.
 
                                        9
<PAGE>   12
 
     Net sales for the first nine months of 1996 were $255.3 million, an
increase of 16.3% over the same period of the prior year. This increase was
primarily the result of strong market demand for the Company's mixing and
turbine agitation equipment, glass-lined storage and reactor vessels and
oilfield products. These products are primarily sold to the pharmaceuticals, oil
and gas recovery and specialty chemicals markets. In addition, the Company
expanded its aftermarket business from the prior year, resulting in increased
sales. Company backlog was $114 million at May 31, 1996, $6 million higher than
at August 31, 1995 and $15 million higher than at May 31, 1995.
 
     Despite higher sales levels in 1996, the gross profit percentage of 33.3%
for the first nine months of 1996 was relatively consistent with 33.4% for the
first nine months of 1995, because the gross margins for the products with the
greatest sales increases, industrial mixers and reactor vessels, are
traditionally lower than the Company's other products. Margins for industrial
mixers and reactor vessels, however, have improved over the prior year as a
result of higher volume and profitability improvement measures, including
restructuring, implemented by the Company.
 
     Engineering and development, selling and administrative expenses decreased
as a percentage of sales from 24.3% in the first nine months of 1995 to 22.8% in
the first nine months of 1996. This decrease resulted from the higher sales
volume and the fixed nature of certain of these expenses.
 
     Other (income) expense for the first nine months of 1995 includes a
one-time write-off of $1.6 million of the Company's investment in Hazleton
Environmental. The Company has no ongoing exposure to further losses related to
this investment.
 
     Interest expense decreased to $5.3 million in the first nine months of 1996
from $5.6 million in the same period of the prior year as a result of slightly
lower interest rates in 1996.
 
     The estimated annual effective tax rate was 37.0% in the first nine months
of 1996 compared to 39.7% in the first nine months of 1995. The tax rate for the
first nine months of 1995 reflects the effect of the nondeductibility of a
portion of the write-off of the investment in Hazleton Environmental. The
Company believes that the 1996 tax rate is more reflective of the Company's
ongoing operations.
 
     During the first nine months of 1995, the Company realized an extraordinary
gain of $1.3 million, net of tax, related to the early extinguishment of certain
debt.
 
     FISCAL 1995.  Net sales reached $303.0 million and net income rose to $13.2
million or $1.21 per share, fully-diluted. This compares to net sales of $121.6
million and net income of $6.4 million or $.61 per share for 1994. The increase
in both sales and net income is due primarily to the acquired companies.
However, it should be noted that the Company's existing businesses also
experienced growth with net sales of such operations reaching $102.5 million, an
11% increase over 1994. Operating income of these businesses, which excludes
corporate, interest and amortization expense, reached $19.4 million, a 10%
increase over 1994.
 
     The rate of profitability, as measured by the ratio of operating income to
sales, declined for domestic operations in both 1994 and 1995 because the rate
of profitability for the acquired businesses was lower than that of the
Company's historic businesses.
 
     Profitability in 1995 was further impacted by the fact that the Company's
foreign businesses were less profitable than its domestic businesses. In 1995,
the European businesses were affected primarily by the German operation which
accounted for 52% of European sales but was only nominally profitable. A program
for changing the way the Company conducted business in Germany and the related
cost structure was commenced in fiscal 1995. The lower rate of profitability for
the other foreign businesses was due in part to their being start-up operations.
 
     Operating income also includes a pre-tax write-off of $1.6 million
representing the value of the Company's investment in Hazleton Environmental.
 
     The Company in May 1995 repurchased $25 million of subordinated debt issued
as a part of the consideration for the acquired companies. The transaction
generated an after-tax extraordinary gain of $1.3 million.
 
                                       10
<PAGE>   13
 
     FISCAL 1994.  The acquisitions and related restructure transactions had a
significant impact on 1994 operating results. Aided by the inclusion of the
acquired businesses for July and August, net sales increased to $121.6 million,
or 43% greater than net sales for 1993 and net income increased to $6.4 million,
or 3% greater than income before cumulative effect of accounting changes earned
for 1993. For the period owned, the acquired businesses accounted for $29.3
million of net sales and provided sufficient income before tax to cover the
additional interest and amortization expense incurred as a result of the
transaction.
 
     The Company's existing businesses also grew in 1994. Net sales increased
8.5% and net income, before considering the restructure provision for the year,
increased 28% over 1993 levels. Improved sales were seen in products for the
oilfield and industrial mixer markets. In addition, improved operating results
were seen in Europe related to the restructuring process that took place there
during the year. Orders improved for all existing products, with year-end
backlog having increased 5% over that of the prior year.
 
     The Pfaudler(R) business unit had been in the process of restructuring its
operations prior to being acquired by the Company. The provisions were primarily
for employee termination costs and related to the operations in Rochester, N.Y.,
Mexico and Germany. The actions in Rochester, N.Y. and the curtailment of new
product manufacturing operations in Mexico were completed as planned in 1995.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     During the first nine months of 1996, 3.7 million outstanding stock
appreciation rights were retired for $18 million. Also during this period, $9
million was used for capital expenditures and $8 million for working capital.
These cash requirements, aggregating $35 million, were funded from operations
and net borrowings of $11 million under the Company's bank credit facility.
 
     The Company is investing $16 million in capital expenditures in 1996 and
anticipates capital expenditures of $21 million in 1997, including approximately
$5 million for a new Houston, Texas facility and equipment for the Moyno
oilfield equipment business.
 
     In the first nine months of 1995, the significant uses of cash were capital
expenditures and acquisitions of $17 million and net debt payments of $5
million. These requirements were funded by cash generated from operations of $19
million. The net result was a decrease of $4.3 million in cash balances for the
first nine months of 1995.
 
     The Company expects operating cash flow to be adequate for operating needs,
including scheduled debt service, capital expenditure plans and shareholder
dividend requirements, during the fiscal years 1996 and 1997.
 
     The Company's current bank credit agreement is secured by all domestic
assets except land and buildings and contains certain restrictive covenants
which include, among other things, requirements relating to tangible net worth,
working capital, additional debt, indebtedness ratios, debt service coverage and
payment of cash dividends. The Company may not, without the consent of the
banks, incur additional borrowings except for borrowings under such bank credit
facility. The banks have consented to the offering and sale of the Notes.
 
     At May 31, 1996, the Company had approximately $30 million available under
its current bank credit facility. Primarily as a result of borrowings in August
1996 to repurchase the Repurchased Obligations for approximately $25 million
plus accrued interest, the amount available to the Company under such bank
credit facility was reduced to $13 million at September 18, 1996. As discussed
in "Use of Proceeds," the Company will repay certain of its bank indebtedness
with the net proceeds from the sale of the Notes. Assuming the Company had
received and applied such net proceeds on September 18, 1996, the amount
available under the Company's bank credit facility at September 18, 1996 would
have been approximately $57 million.
 
     The Company has entered into negotiations with respect to a replacement
bank facility which would provide certain more favorable terms than the existing
facility and would add up to $50 million of additional availability for purposes
of financing future acquisitions.

<PAGE>   14
 
                                    BUSINESS
 
     The Company designs, manufactures and markets high-performance, specialized
fluids management products for the process industries on a global basis. The
Company's four product lines are glass-lined reactor and storage vessels (38% of
fiscal 1995 sales), progressing cavity products (30%), mixing and turbine
agitation equipment (22%), and related products, such as engineered systems,
fluoropolymer products, and valves (10%).
 
     The Company has achieved leading market shares in each of its main product
lines: the Company believes that it is first worldwide in glass-lined storage
and reactor vessels, first in North America in progressing cavity products, and
second worldwide in mixing and turbine agitation equipment. The Company also
believes that its principal brand names -- Pfaudler(R), Moyno(R), and 
Chemineer(R) -- are well-known in the marketplace and are associated with 
quality products and extensive customer support, including product application
engineering, state-of-the-art customer test facilities, and strong aftermarket
service and support.
 
     The Company markets its products to the process industries -- industries in
which the pumping, mixing, treatment, chemical processing, measurement, and
containment of fluids and particulates are important elements in their
production processes. The principal sectors of the process industries served by
the Company are specialty chemicals, pharmaceuticals, oil and gas recovery,
wastewater treatment, food and beverage, and pulp and paper.
 
     An important element of the Company's strategy has been to develop a
balanced group of businesses serving diverse markets. In fiscal 1995,
international sales represented approximately 45% of total Company sales,
aftermarket sales represented approximately 38% of total Company sales and at
least 5% of total Company sales were derived from each of its five primary end
markets.
 
COMPETITIVE STRENGTHS
 
     In 1992, the Company identified specific areas of the fluids management
industry in which it believed significant growth opportunities were available
and embarked on a strategy with the primary objective of becoming a global
fluids management company and a leader in its chosen markets. Through a series
of acquisitions and internal actions, the Company believes that it has developed
significant competitive strengths which enable it to realize more effectively
its goal of providing customers with comprehensive and innovative solutions to
their fluids management needs while sustaining significant levels of profitable
growth.
 
     The Company believes that its success is attributable to:
 
     A Record of Successful Acquisitions.  Since 1992, the Company has completed
and integrated eight acquisitions in the fluids management industry. These
acquisitions have more than tripled the sales of the Company and have helped the
Company to better serve the requirements of many of its customers by offering a
more diverse product line. Several of the businesses acquired by the Company
were unprofitable or marginally profitable at the time at which they were
acquired. The Company has demonstrated an ability to improve the operating
performance of all of its acquisitions, including that of Pfaudler(R), 
Chemineer(R) and Edlon(R), which, on a combined basis, improved from an 
operating margin of 8.7% for the nine month period ended May 31, 1995 to 11.0%
for the nine month period ended May 31, 1996.
 
     Global Presence.  The Company has responded to the globalization of the
process industries by establishing manufacturing, sales and service capabilities
in numerous international markets (which markets accounted for approximately 45%
of sales in fiscal 1995). The Company maintains facilities in emerging markets
such as Mexico, Brazil, India, Singapore and China, as well as in established
markets such as England, Germany, Scotland and Belgium. By implementing a
network of local manufacturing and service facilities, the Company believes that
it can better respond to the global sourcing requirements of its multinational
customer base while realizing substantial market penetration and cost savings
associated with operating within local markets.

     Fluids Management Applications Expertise.  The Company brings to its
customers a broad knowledge of the component products of fluids management
systems and a commitment to understanding the application engineering
requirements of its customers. As a result, the Company is able to meet its
customers' expectations of innovative and cost-effective solutions to their
requirements. In addition, in each of its businesses, the Company maintains
state-of-the-art test facilities which the Company and customer engineers use
jointly to test and develop particular equipment and system configurations.
 
     Aftermarket Support.  The Company believes that the ability to serve
customers globally requires strong aftermarket service and support. In 1995, the
Company augmented its aftermarket business with the acquisition of Pharaoh and
Cannon, which it integrated with its existing aftermarket operations to form
dedicated aftermarket subsidiaries in the United States and the United Kingdom.
Through these subsidiaries, the Company provides aftermarket service and support
to its own customers, as well as to customers of the Company's competitors
which, along with the substantial growth of the Company's installed base of
products, provides a stable source of higher margin aftermarket business. The
Company believes that its dedication to aftermarket support reinforces its image
of dependability with its customers, leading to increased business
opportunities.
 
     Recognized Technologies and Brand Names.  The Company believes that it is
recognized within its markets as a leader in certain core technologies which are
fundamental to its success and that its Moyno(R), Pfaudler(R) and Chemineer(R)
brand names are associated throughout the process industries with high
performance, innovation and quality. The Company's core technologies are
pressure vessel construction and glass coating of metal substrates
(Pfaudler(R)), fluid dynamics engineering (Chemineer(R)), progressing cavity
technology (Moyno(R)) and fluoropolymer coating (Edlon(R)). The Company
believes that its established brand names and core technologies offer its
existing customers assurances of dependability and product support while
affording the Company competitive advantages in gaining new business.
 
GROWTH STRATEGY
 
     The Company has used its competitive strengths to achieve substantial
growth over the past several years. From fiscal 1991 through fiscal 1995, the
Company's sales and income before interest and taxes increased at a compound
annual rate of 40.1% and 31.6%, respectively, and for the nine months ended May
31, 1996 the Company's sales and income before interest and taxes increased
16.3% and 33.2%, respectively, as compared to the nine months ended May 31, 1995
(comparative figures are before the write-off of the Company's investment in
Hazleton Environmental in the third quarter of fiscal 1995). The sales growth
from 1991 through 1995 primarily was driven by eight acquisitions completed
since February 1992 at an aggregate purchase price of approximately $160
million:

     The Company seeks to continue to grow by (i) capitalizing on the inherent
growth of its end markets; (ii) exploiting opportunities for industry
consolidation within existing markets; (iii) expanding geographically, both
internally and through acquisitions; and (iv) establishing new product lines
through acquisitions.
 
     Capitalize on Market Growth Opportunities.  Over 40% of the Company's sales
are derived from high-growth markets such as oil and gas recovery,
pharmaceuticals and food additives and supplements, with the remainder derived
from other process industries such as specialty chemicals, wastewater treatment
and pulp and paper. The Company maintains leading positions in each of its
primary product lines and believes that it will benefit substantially from any
inherent growth in its end markets. Additionally, the Company seeks to expand
upon the inherent growth of its end markets by identifying and responding to new
technology trends with value-added products and by applying its existing
products to new market niches.
 
     Exploit Industry Consolidation.  The Company believes that it will benefit
from the trends among its customers to limit their supplier base, to favor
global suppliers and to require a higher level of application engineering
expertise from their suppliers, which is leading to consolidation among the
manufacturers of fluids management equipment. Both positive displacement pumps
and industrial mixers, which collectively account for over 50% of the Company's
sales, are highly fragmented industries and should offer the Company significant
acquisition opportunities. The Company believes that the greatest opportunities
for consolidation are in the positive displacement pump industry, which the
Company estimates has combined domestic annual sales of $700 million. In
addition, the Company believes that there are consolidation opportunities in the
domestic industrial mixer industry, which includes a number of smaller
manufacturers with combined domestic sales of approximately $100 million.
 
     Expand Geographically.  The Company believes that it successfully can
increase the rate of penetration of its products in high-growth, emerging
markets--Asia/Pacific Rim and South America--by leveraging the Company's strong
brand name recognition and its relationships with multinational customers. In
addition, the Company believes that there are opportunities for it to utilize
its existing presence in certain emerging markets to introduce other product
lines currently offered by the Company. The Company seeks other opportunities to
expand geographically, including acquisitions of existing businesses and the
formation of joint ventures/alliances, each of which the Company believes are
low risk and effective methods of entering new geographic markets. By taking
advantage of opportunities to expand geographically, the Company seeks to grow
at a rate which exceeds that of its end markets, while meeting its customers'
global sourcing needs.
 
     Acquire New Product Lines.  The process industries utilize a number of
fluids management products which the Company does not manufacture or which
currently represent an insignificant portion of the Company's sales. The Company
considers and evaluates on an ongoing basis acquisition opportunities in several
of these product areas, including valves, filters and grinders, and may, in the
future, acquire one or more such businesses. It is unlikely, however, that the
Company would acquire a related product line unless it were able by such
acquisitions to establish a major market position.
 
MARKETS SERVED
 
     The Company markets its fluids management products and services to the
process industries -- industries in which the pumping, mixing, treatment,
chemical processing, measurement and containment of fluids and particulates are
important elements in their manufacturing or production processes. The principal
sectors of the process industries served by the Company are oil and gas
recovery, pharmaceuticals, specialty chemicals, food and beverage, pulp and
paper and wastewater treatment.

Specialty Chemicals     40%
Pharmaceuticals         25%
Food & Beverage          4%
Other                    5%
Pulp & Paper             5%
Wastewater Treatment     8%
Oil & Gas Recovery      13%
 
     The companies included in these sectors of the process industries tend to
be large, often with global operations. Capital expenditures for equipment in
each sector are driven by a variety of factors, such as market growth rates, new
product introduction, globalization and cost control. Economic cycles tend to
differ among sectors, and the Company believes that general economic downturns
have less of an impact on capital expenditures in the pharmaceuticals, oil and
gas recovery and food and beverage industries.
 
     Oil and Gas Recovery.  The Company's sales to the oil and gas recovery
market include (i) progressing cavity down-hole pumps used in lifting oil to the
surface and dewatering of gas wells; (ii) progressing cavity power sections used
to drive the drilling element in directional drilling operations; and (iii)
aftermarket products and services such as replacement power sections, relining
of down-hole pump stators and replacement of rotors. For the last five fiscal
years, the Company's sales of oil and gas recovery products have grown at an
annual rate of 19%. The Company believes its growth prospects primarily are
driven by the trend in the industry to adopt the latest oil and gas
technologies, including 3-D seismic analysis which, in conjunction with
directional drilling methods and versatile down-hole pumps, facilitates recovery
of oil and gas from difficult to reach formations. In addition, changing
geopolitics have resulted in more countries opening their borders to
privatization in the exploration and development of their oil and gas
properties. In response to increased demand within the oil and gas recovery
market and to maintain its technological advantages, the Company currently is
developing a facility in Houston, Texas dedicated to the production of down-hole
pumps and power drilling sections which is scheduled to begin operation in
fiscal 1997.
 
     Pharmaceuticals.  The Company's products perform critical functions in the
production of pharmaceuticals by providing temperature, agitation and
pressure-controlled environments for complex chemical reactions which require
exact formulations, repeatability and high levels of purity. In addition, the
Company's products are reconditioned on a regular basis because of the severe
operating conditions to which the Company's products are exposed and the need to
maintain a pure processing environment. The Company believes that it will
benefit from the long-term trend of high levels of capital expenditures within
the pharmaceuticals industry. This trend is driven by the
 
                                       15
<PAGE>   18
 
significant industry growth rates resulting from globalization of manufacturing
facilities to serve emerging markets and development of innovative drugs which
often require new process facilities or retrofit of existing facilities.
 
     Specialty Chemicals.  Substantially all of the Company's products sold to
the chemical industry consist of specialized equipment and aftermarket products
and services for use in the batch processing of specialty chemicals rather than
for use in the continuous processing of commodity chemicals. Unlike commodity
chemicals, such as basic petrochemicals and inorganic commodities, specialty
chemicals are downstream products, such as intermediate products directed to the
pharmaceuticals industry, which are more highly processed and refined. The
Company believes that, because producers of specialty chemicals are value-added,
strategic suppliers to their customers, pricing pressure and volatility are less
severe than in other segments of the chemical industry.
 
     Other Markets.  The Company's industrial mixer and pump products also serve
the food and beverage, pulp and paper and wastewater treatment industries.
Long-term growth in these markets should approximate the growth in general
economic activity, with certain segments such as food additives and supplements
and international markets growing faster than the overall domestic market.
 
PRODUCTS
 
     Glass-Lined Storage and Reactor Vessels.  The Company's Pfaudler(R) unit
manufactures and sells glass-lined reactor and storage vessels and related
equipment for use in the pharmaceuticals and specialty chemicals industries.
Reactor vessels perform critical functions in the production process by
providing a temperature, agitation and pressure controlled environment for often
complex chemical reactions.
 
     The Pfaudler(R) unit fabricates steel vessels and bonds glass to the
interior of vessels to form a fused composite, referred to as Glasteel(R), which
provides a vessel in which materials can be processed or stored in an inert,
nonsticking, corrosion-resistant, pressure-controlled environment. Reactor
vessels range in capacities from one to 15,000 gallons, are generally
custom-ordered and designed and can be equipped with various accessories, such
as agitators, instrumentation and baffles. Storage vessels have capacities of up
to 25,000 gallons.
 
     Aftermarket products and services consist of reconditioning and reglassing
reactor vessels, replacement of vessel parts and accessories and field service.

     Progressing Cavity Products.  Progressing cavity technology is used in
down-hole pumps and power sections for the oil and gas recovery industry, as
well as in other process industries such as specialty chemicals, food and
beverage, pulp and paper and wastewater treatment. A progressing cavity pump
consists of a high-strength, single helix steel rod (called the rotor) which
rotates in a double helix elastomer-lined steel tube (called the stator). The
rotor generates positive displacement in the stator to deliver uniform fluid
flow, at rates proportional to the rotational speed of the rotor.
 
     For the oil and gas recovery industry, the Company manufactures and sells
down-hole pumps and power sections used to drive the drilling element in the
drilling of wells. The ability of progressing cavity technology to be used in
severe pumping applications and also as a hydraulic
 
                                       16
<PAGE>   19
 
motor has enabled the Company to become a leader in the development of pumping
and directional drilling products. Moyno(R) down-hole pumps are used primarily
to pump heavy crude oil to the surface and for dewatering gas wells. Moyno(R)
down-hole power sections utilize progressing cavity technology to drive the
drilling element in oil and gas well drilling.
 
     For other process industries, the Company markets a wide range of
progressing cavity pumps under the brand names Moyno(R) and R&M(R). Progressing
cavity pumps are versatile as they can be positioned at any angle and can
deliver flow in either direction, without modification or accessories. These
pumps are able to handle fluids ranging from high pressure water and
shear-sensitive materials to heavy, viscous, abrasive, solid-laden slurries and
sludges.
 
     Aftermarket products and services consist of replacement power sections,
relining of the elastomer component of down-hole pump stators and replacement of
rotors.

                              DESCRIPTION OF NOTES
 
     The Notes are to be issued under an Indenture, dated as of September 18,
1996 (the "Indenture"), between the Company and Star Bank, N.A., as Trustee (the
"Trustee"). A draft of the Indenture has been filed as an exhibit to the
Registration Statement referred to below under "Available Information". The
following summarizes the material provisions of the Indenture and is subject to,
and qualified in its entirety by reference to, all the provisions of the
Indenture, including the definition therein of certain terms. Wherever
particular articles, sections or defined terms of the Indenture are referred to,
it is intended that such articles, sections or defined terms shall be
incorporated herein by reference.
 
GENERAL
 
     The Notes will be limited to $60,000,000 aggregate principal amount (or
$65,000,000 aggregate principal amount assuming exercise in full of the
Underwriters' over-allotment option), will be unsecured subordinated obligations
of the Company, and will mature on September 1, 2003. The
 
                                       21
<PAGE>   24
 
Notes will bear interest from September 24, 1996 at the rate per annum shown on
the cover page of this Prospectus. Interest will be payable semiannually on
March 1 and September 1 of each year ("Interest Payment Dates"), subject to
certain exceptions, commencing March 1, 1997, to the persons in whose names the
Notes are registered at the close of business on the 15th day of February or
August, as the case may be ("Regular Record Date"), next preceding such Interest
Payment Date. Principal of, premium, if any, and interest on the Notes will be
payable, and the Notes will be convertible and exchangeable and transfers
thereof will be registrable, at the office of the Trustee or the office or
agency of the Company maintained for such purpose in The City of New York and at
any other office or agency maintained by the Company for such purpose, provided
that at the option of the Company, payment of interest may be made by check
mailed to the address of the person entitled thereto as it appears in the Note
Register. All payments of interest and principal will be made in United States
Dollars. (Sections 3.1, 3.5, 3.7, 10.2, 12.2 and 13.1)
 
     The Notes will be issued only in registered form without coupons in
denominations of $1,000 or any integral multiple thereof. (Section 3.2) No
service charge will be made for any registration of transfer or exchange of
Notes, but the Company may require payment of a sum sufficient to cover any tax
or other governmental charge payable in connection therewith. (Section 3.5)
 
CONVERSION RIGHTS
 
     The Notes will be convertible into Common Shares at any time prior to
redemption (except as set forth in the following sentence) or maturity,
initially at the conversion price stated on the cover page hereof. The right to
convert Notes called for redemption will terminate at the close of business on
the Business Day immediately preceding a Redemption Date and will be lost if not
exercised prior to that time. (Section 12.1) See "Optional Redemption."
 
     Notes surrendered for conversion during the period from the close of
business on any Regular Record Date next preceding any Interest Payment Date to
the opening of business on such Interest Payment Date (except Notes called for
redemption on a Redemption Date within such period) must be accompanied by
payment of an amount equal to the interest thereon which the registered Holder
is to receive on such Interest Payment Date. No other adjustment for interest or
dividends is to be made upon conversion. (Sections 3.7 and 12.2) Fractional
Common Shares will not be issued upon conversion, but in lieu thereof, the
Company will pay a cash adjustment based upon market price. (Section 12.3)
 
     The Conversion Price is subject to adjustment (under the formula set forth
in the Indenture) under certain circumstances, including: (i) the issuance of
Common Shares as a dividend or distribution on Common Shares; (ii) the issuance
to all holders of Common Shares of rights or warrants entitling them to
subscribe for or purchase Common Shares at a price per share less than the
Current Market Price; (iii) certain subdivisions and combinations of Common
Shares; (iv) the issuance as a dividend or distribution to all holders of Common
Shares of capital shares of the Company (other than Common Shares) or evidences
of its indebtedness, cash or other assets (including securities, but excluding
those rights, warrants, dividends and distributions referred to above and
dividends and distributions paid exclusively in cash and excluding any capital
shares, evidences of indebtedness, cash or assets distributed upon a
consolidation or merger to which the provision described in the last sentence of
this paragraph applies); (v) dividends or other distributions consisting
exclusively of cash (excluding any cash that is distributed upon a merger or
consolidation to which the provision described in the last sentence of this
paragraph applies and any cash portion of distributions referred to in clause
(iv)) to all holders of Common Shares to the extent such distributions, combined
with (A) all such cash distributions made within the preceding 12 months in
respect of which no adjustment has been made, plus (B) any cash and the fair
market value of other consideration payable in respect of any tender offer by
the Company or any of its subsidiaries for Common Shares concluded within the
preceding 12 months in respect of which no adjustment has been made, exceeds 10%
of the Company's market capitalization (being the product of the then current
market price of the Common Shares times the number of Common
 
                                       22
<PAGE>   25
 
Shares then outstanding) on the record date for such distribution; and (vi) the
purchase of Common Shares pursuant to a tender offer made by the Company or any
of its subsidiaries to the extent that the aggregate consideration, together
with (X) any cash and the fair market value of any other consideration payable
in any other such tender offers expiring within the 12 months preceding such
tender offer in respect of which no adjustment has been made, plus (Y) the
aggregate amount of any such all-cash distributions referred to in clause (v)
above to all holders of Common Shares within the 12 months preceding the
expiration of such tender offer in respect of which no adjustments have been
made, exceeds 10% of the Company's market capitalization on the expiration of
such tender offer. The foregoing provisions for adjustment are subject to
certain exceptions, as set forth in the Indenture. (Section 12.4) In the case of
certain consolidations or mergers to which the Company is a party or the
conveyance or transfer of the properties and assets of the Company substantially
as an entirety, each Note then outstanding shall, without the consent of any
Holders of Notes, become convertible only into the kind and amount of
securities, cash and other property receivable upon such consolidation, merger,
conveyance or transfer by a holder of the number of Common Shares into which the
Note might have been converted immediately prior to such consolidation, merger,
conveyance or transfer, assuming such holder of Common Shares failed to exercise
his rights of election, if any, as to the kind or amount of securities, cash and
other property receivable upon such consolidation, merger, conveyance or
transfer (provided that if the kind or amount of securities, cash and other
property so receivable is not the same for each non-electing share, then the
kind and amount of securities, cash and other property so receivable by each
non-electing share shall be deemed to be the kind and amount so receivable per
share by a plurality of the non-electing shares). (Section 12.10)
 
SUBORDINATION OF NOTES
 
     The Notes will be subordinated and subject, to the extent and in the manner
set forth in the Indenture, to the prior payment in full of all Senior
Indebtedness. (Section 13.1) Senior Indebtedness is defined to include the
principal of, and premium, if any, and interest on and other amounts due on any
indebtedness, whether now outstanding or hereafter created, incurred, assumed or
guaranteed by the Company, for money borrowed from others (including obligations
under capitalized leases or purchase money indebtedness) or in connection with
the acquisition by the Company or a Subsidiary of any other business or entity,
or in respect of letters of credit or bid, performance or surety bonds issued
for the account or on the credit of the Company or a Subsidiary, and, in each
case, all renewals, extensions and refundings thereof, other than (i) any such
indebtedness as to which, in the instrument creating or evidencing the same, it
is provided that such indebtedness is not superior in right of payment to the
Notes, (ii) indebtedness of the Company to any Affiliate and (iii) the Notes.
(Section 1.1) At September 18, 1996, the Company had approximately $75,507,000
of outstanding indebtedness that would have constituted Senior Indebtedness
under the Indenture. The Indenture does not limit the amount of Senior
Indebtedness or other indebtedness that the Company or its Subsidiaries may
incur.
 
     No payments of principal of, premium, if any, or interest on the Notes may
be made and no Notes may be redeemed, retired or purchased if the Company is
then in default in the payment of any Senior Indebtedness or if at the time any
other Event of Default under the terms of any Senior Indebtedness exists
permitting acceleration thereof. Upon any payment or distribution of assets of
the Company in the event of any insolvency, reorganization, liquidation or
similar proceeding, all Senior Indebtedness must be repaid in full (including
any interest thereon accruing after the commencement of any such proceeding)
before the Holders of the Notes will be entitled to receive or retain any
payment. If the Notes are declared due and payable before their Stated Maturity
because of the occurrence of an Event of Default, no payment may be made in
respect of the Notes unless and until all Senior Indebtedness shall have been
paid in full or such declaration and its consequences shall have been rescinded
and all such defaults shall have been remedied or waived. (Section 13.2)
 
                                       23
<PAGE>   26
 
     By reason of such subordination, in the event of insolvency, creditors of
the Company who are holders of Senior Indebtedness may recover more, ratably,
than Holders, and creditors of the Company who are neither holders of Senior
Indebtedness nor Holders may recover less, ratably, than holders of Senior
Indebtedness and may recover more, ratably, than Holders.
 
     The Notes are structurally subordinated in right of payment to all
liabilities (including trade payables) of the Company's Subsidiaries. The
Company's Subsidiaries had approximately $93,856,000 of liabilities (including
trade payables but excluding inter-company liabilities) outstanding at August
31, 1996.
 
OPTIONAL REDEMPTION
 
     The Notes will be redeemable upon not less than 30 nor more than 60 days'
notice by mail at any time on or after September 1, 1999, as a whole or in part,
at the election of the Company, at a Redemption Price equal to the percentage of
the principal amount set forth below if redeemed in the 12-month period
beginning September 1 of the years indicated:
 
<TABLE>
<CAPTION>
                 REDEMPTION
YEAR               PRICE
- -----            ----------
<S>              <C>
1999               103.25%
2000               102.17%
2001               101.09%
</TABLE>
 
and thereafter at a Redemption Price equal to 100% of the principal amount,
together in each case with accrued and unpaid interest to the Redemption Date
(subject to the right of Holders of record on Regular Record Dates to receive
interest due on an Interest Payment Date), provided that the Company may not
redeem any Notes prior to September 1, 1999. (Sections 2.3, 11.1, 11.4, 11.5 and
11.6)
 
CERTAIN RIGHTS TO REQUIRE REPURCHASE OF NOTES BY THE COMPANY
 
     In the event of any Change in Control (as defined below) of the Company
occurring after the date of issuance of the Notes and on or prior to Maturity,
each Holder of Notes will have the right, at such Holder's option, to require
the Company to repurchase all or any part of such Holder's Notes on the date
(the "Repurchase Date") that is 75 days after the date the Company gives notice
of the Change in Control (as described below) at a price (the "Repurchase
Price") equal to 100% of the principal amount thereof, together with accrued and
unpaid interest to the Repurchase Date. (Section 14.1) On or prior to the
Repurchase Date, the Company is required to deposit with the Trustee or a Paying
Agent an amount of money sufficient to pay the Repurchase Price of the Notes
which are to be repaid on the Repurchase Date. (Section 14.3) Neither the Board
of Directors of the Company nor the Trustee, acting alone or together, can
modify or waive this required repurchase of the Notes.
 
     Failure by the Company to repurchase the Notes when required under the
preceding paragraph will result in an Event of Default under the Indenture
whether or not such repurchase is permitted by the subordination provisions of
the Indenture. (Section 5.1)
 
     On or before the 15th day after the occurrence of a Change in Control, the
Company is obligated to mail to all Holders a notice of the event constituting
and the date of such Change in Control, the Repurchase Date, the date by which
the repurchase right must be exercised, the Repurchase Price for Notes, and the
procedures which a Holder must follow to exercise a repurchase right. To
exercise the repurchase right, a Holder of a Note must deliver, on or before the
10th day prior to the Repurchase Date, written notice to the Company (or an
agent designated by the Company for such purpose) and to the Trustee of the
Holder's exercise of such right, together with the certificates evidencing the
Notes with respect to which the right is being duly exercised, duly endorsed for
transfer. (Section 14.2)
 
                                       24
<PAGE>   27
 
     A "Change in Control" will occur when: (i) all or substantially all of the
Company's assets are sold as an entirety to any person or related group of
persons; (ii) there shall be consummated any consolidation or merger of the
Company (A) in which the Company is not the continuing or surviving corporation
(other than a consolidation or merger with a wholly-owned subsidiary of the
Company in which all Common Shares outstanding immediately prior to the
effectiveness thereof are changed into or exchanged for the same consideration)
or (B) pursuant to which the Common Shares are converted into cash, securities
or other property, in each case other than a consolidation or merger of the
Company in which the holders of the Common Shares immediately prior to the
consolidation or merger have, directly or indirectly, at least a majority of the
common shares of the continuing or surviving corporation immediately after such
consolidation or merger; or (iii) any person, or any persons acting together
which would constitute a "group" for purposes of Section 13(d) of the Exchange
Act, together with any Affiliates thereof, acquires beneficial ownership (as
defined in Rule 13d-3 under the Exchange Act) of at least 50% of the total
voting power of all classes of capital shares of the Company entitled to vote
generally in the election of directors of the Company. Notwithstanding clause
(iii) of the foregoing definition, a Change in Control will not be deemed to
have occurred solely by virtue of the Company, any Subsidiary, any employee
share purchase plan, share option plan or other share incentive plan or program,
retirement plan or automatic dividend reinvestment plan or any substantially
similar plan of the Company or any Subsidiary or any person holding securities
of the Company for or pursuant to the terms of any such employee benefit plan,
filing or becoming obligated to file a report under or in response to Schedule
13D or Schedule 14D-1 (or any successor schedule, form or report) under the
Exchange Act disclosing beneficial ownership by it of shares or securities of
the Company, whether at least 50% of the total voting power referred to in
clause (iii) of the foregoing definition or otherwise. (Section 14.5) A
recapitalization or a leveraged buyout or similar transaction involving members
of management or their Affiliates will constitute a Change in Control if it
meets the foregoing definition.
 
     Notwithstanding the foregoing, a Change in Control as described above will
not be deemed to have occurred if (i) the Current Market Price of the Common
Shares on the date of a Change in Control is at least equal to 105% of the
conversion price of the Notes in effect immediately preceding the time of such
Change in Control, or (ii) all of the consideration (excluding cash payments for
fractional shares) in the transaction giving rise to such Change in Control to
the holders of Common Shares consists of common shares that are, or immediately
upon issuance will be, listed on a national securities exchange or quoted on the
Nasdaq National Market, and as a result of such transaction the Notes will
become convertible solely into such common shares, or (iii) the consideration in
the transaction giving rise to such Change in Control to the holders of Common
Shares consists of cash or securities that are, or immediately upon issuance
will be, listed on a national securities exchange or quoted on the Nasdaq
National Market, or a combination of cash and such securities, and the aggregate
fair market value of such consideration (which, in the case of such securities,
will be equal to the average of the daily Closing Prices of such securities
during the 10 consecutive trading days commencing with the sixth trading day
following consummation of such transaction) is at least 105% of the conversion
price of the Notes in effect on the date immediately preceding the closing date
of such transaction. (Section 14.5)
 
     There is no definition of the phrase "all or substantially all" as applied
to the Company's assets and used in the definition of Change in Control in the
Indenture, and there is no clear definition of the phrase under applicable law.
As a result of the uncertainty of the meaning of this phrase, in the event the
Company were to sell a significant amount of its assets, the Holders and the
Company may disagree over whether the sale gave rise to the right of Holders to
require the Company to repurchase the Notes. In such event, the Holders would
likely not be able to require the Company to repurchase unless and until the
disagreement were resolved in favor of the Holders.
 
     The right to require the Company to repurchase Notes as a result of a
Change in Control could create an Event of Default under Senior Indebtedness, as
a result of which any repurchase could,
 
                                       25
<PAGE>   28
 
absent a waiver, be blocked by the subordination provisions of the Notes. See
"Subordination of Notes." The Company's ability to pay cash to the Holders upon
a repurchase may also be limited by certain financial covenants contained in the
Company's Senior Indebtedness.
 
     In the event a Change in Control occurs and the Holders exercise their
rights to require the Company to repurchase Notes, the Company intends to comply
with applicable tender offer rules under the Exchange Act, including Rules 13e-4
and 14e-1, as then in effect, with respect to any such purchase. The Change of
Control purchase feature of the Notes may in certain circumstances make more
difficult or discourage a takeover of the Company and, thus, the removal of
incumbent management. The Change in Control purchase feature, however, is not
the result of management's knowledge of any specific effort to accumulate Common
Shares or to obtain control of the Company by means of a merger, tender offer,
solicitation or otherwise, or part of a plan by management to adopt a series of
anti-takeover provisions. Instead, the Change in Control purchase feature is a
standard term contained in other similar debt offerings and the specific terms
of this feature resulted from negotiations between the Company and the
Underwriters. Management has no present intention to engage in a transaction
involving a Change in Control.
 
     The foregoing provisions would not necessarily afford Holders protection in
the event of highly leveraged or other transactions involving the Company that
may adversely affect Holders.
 
SINKING FUND
 
     There will be no sinking fund established for the retirement of the Notes.
 
MODIFICATION OF THE INDENTURE
 
     Modifications and amendments of the Indenture may be made by the Company
and the Trustee with the consent of the Holders of two-thirds in principal
amount of the Outstanding Notes; provided that no such modification or amendment
may, without the consent of the Holder of each Outstanding Note affected
thereby, (i) change the stated maturity date of the principal of, or any
installment of interest on, any Note, (ii) reduce the principal amount of, the
rate of interest thereon, or any premium payable on, any Notes, (iii) change the
place of payment where, or the coin or currency in which, any Note or any
payment or the interest thereon is payable, (iv) impair the right to institute
suit for the enforcement of any such payment when due, (v) adversely affect the
conversion rights of the Holders, (vi) modify the provisions of the Indenture
with respect to the subordination of the Notes in a manner adverse to the
Holders, (vii) adversely affect the right to require the Company to repurchase
Notes, or (viii) reduce the percentage in principal amount of Notes the consent
of whose Holders is required for modification or amendment of the Indenture or
for waiver of compliance with certain provisions of the Indenture or for waiver
of certain defaults. (Section 9.2)
 
EVENTS OF DEFAULT, NOTICE AND WAIVER
 
     The following are Events of Default: (i) default in the payment of any
interest on the Notes which continues for 30 days; (ii) default in the payment
of principal or premium, if any, when due; (iii) default in the payment of the
Repurchase Price in respect of any Note on the Repurchase Date; (iv) default in
the performance of any other covenant continued for 60 days after written notice
to the Company as provided in the Indenture; (v) default in respect of
indebtedness of the Company for money borrowed which results in acceleration of
the maturity of $10.0 million or more of indebtedness, if such acceleration is
not rescinded or indebtedness discharged within 30 days after written notice to
the Company as provided in the Indenture; and (vi) certain events in bankruptcy,
insolvency or reorganization. (Section 5.1) If any Event of Default shall happen
and be continuing, the Trustee or the Holders of not less than 25% in principal
amount of the Outstanding Notes may declare the principal of all the Notes due
and payable immediately. (Section 5.2) At any time after a declaration of
acceleration with respect to the Notes has been made, but before a judgment or
decree based on acceleration has been obtained, the Holders of a majority in
principal amount of the
 
                                       26
<PAGE>   29
 
Outstanding Notes may, under certain circumstances, rescind and annul such
acceleration. (Section 5.2)
 
     No Holder will have any right to institute any proceeding with respect to
the Indenture or for any remedy under the Indenture unless (i) the Holder
previously has given to the Trustee written notice of a continuing Event of
Default, (ii) the Holders of not less than 25% in principal amount of the
Outstanding Notes have made written request, and offered reasonable indemnity,
to the Trustee to institute proceedings as Trustee, and (iii) within 60 days
after such request, the Trustee has neither instituted such proceedings nor
received from the Holders of a majority in aggregate principal amount of the
Outstanding Notes a direction inconsistent with the request. (Section 5.7)
 
     The Indenture provides that the Trustee will be under no obligation,
subject to the duty of the Trustee during default to act with the required
standard of care, to exercise any of its rights or powers under the Indenture at
the request or direction of any of the Holders, unless such Holders shall have
offered to the Trustee reasonable indemnification. (Section 6.3) Subject to the
requirement that the Trustee be indemnified, the Holders of a majority in
principal amount of the Outstanding Notes will have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Trustee or exercising any trust or power conferred on the Trustee. (Section
5.12)
 
     The Holders of a majority in principal amount of the Outstanding Notes may
on behalf of the Holders of all Notes waive compliance by the Company with
certain covenants in the Indenture. (Section 10.7) The Holders of a majority in
principal amount of the Outstanding Notes may on behalf of the Holders of all
Notes waive certain past defaults except a default in payment of the principal
of, or premium, if any, or interest on any Note or in respect of a covenant or
provision which under the Indenture cannot be modified or amended without the
consent of the Holder of each Outstanding Note affected. (Section 5.13)
 
     The Company is required to furnish to the Trustee annually a certificate as
to the Company's compliance with the Indenture and specifying each default and
the nature thereof. (Section 7.4(d))
 
CONSOLIDATION, MERGER, CONVEYANCE OR TRANSFER
 
     The Indenture provides that the Company shall not consolidate with or merge
into any other corporation or convey or transfer its properties and assets
substantially as an entirety to any person, unless (i) any such successor
assumes the Company's obligations under the Notes and the Indenture, (ii) after
giving effect thereto, no Event of Default or event which with notice and/or
lapse of time would become an Event of Default shall have occurred and be
continuing and (iii) certain other conditions under the Indenture are met.
(Section 8.1) Upon any such consolidation or merger, or any such conveyance or
transfer of the properties and assets of the Company substantially as an
entirety, the successor corporation formed by such consolidation, or into which
the Company is merged, or to which such conveyance or transfer is made, will
succeed to, and be substituted for, and may exercise every right and power of,
the Company under the Indenture with the same effect as if such successor
corporation had been named as the Company, and thereupon the Company as the
predecessor corporation will be relieved of all obligations and covenants under
the Indenture and the Notes. (Section 8.2)
 
GOVERNING LAW
 
     The Notes will be governed by, and construed in accordance with, the laws

                         DESCRIPTION OF CAPITAL SHARES
 
     The Common Shares are the only class of capital shares of the Company. The
Company is authorized to issue 25,000,000 Common Shares, and at August 31, 1996,
there were 10,597,392 Common Shares outstanding. All of the outstanding Common
Shares are, and any Common Shares issued by the Company upon conversion of the
Notes will be upon issuance, fully paid and non-assessable. Shareholders do not
have pre-emptive rights to purchase any securities of the Company.
 
     Holders of Common Shares are entitled to receive such dividends as may be
declared from time to time by the Board of Directors out of funds legally
available therefor. The ability of the Company to pay dividends is subject to
certain contractual limitations in its credit agreements. Upon liquidation,
holders of Common Shares are entitled to receive a pro rata share of all assets
available to shareholders.
 
     KeyCorp Shareholder Services, Inc. is transfer agent and registrar of the
Common Shares.
 
     Holders of Common Shares are entitled to one vote per share upon all
matters presented to shareholders. Shareholders do, however, have cumulative
voting rights in the election of directors.
 
     Article II of the Company's Code of Regulations divides the Board of
Directors of the Company into two classes, one class comprised of four directors
and one class of three directors. One class of directors is elected each year to
serve for a two-year term. Directors may not be removed from office without the
affirmative vote of the holders of at least two-thirds of the outstanding voting
power of the Company. Article II of the Code of Regulations provides that only
persons who are nominated in accordance with a specified procedure are eligible
for election as directors. The procedure requires that notice of the nomination,
together with the specified information concerning the nominee, must be given to
the Company not less than 50 nor more than 75 days prior to the meeting at which
directors are to be elected. Article II may not be amended or repealed without
the affirmative vote of the holders of at least two-thirds of the voting power
of the Company.
 
CERTAIN OHIO LEGISLATION
 
     Ohio's "Control Share Acquisition Act" generally requires shareholder
approval of any acquisition of shares of an Ohio corporation which would result
in the acquiring person first reaching or exceeding ownership of one-fifth,
one-third or a majority of the total voting power of the corporation. Any such
control share acquisition cannot be consummated unless authorized by the holders
of: (i) a majority of the voting power of the corporation present at a meeting
of shareholders, and (ii) a majority of such voting power other than shares held
by the acquiring person or an officer or an employee who is a director of the
corporation, and other than shares acquired by a person or group after
announcement of the proposed control share acquisition if the amount so acquired
exceeds  1/2% of the outstanding voting shares or was acquired for a
consideration exceeding $250,000.
 
     Ohio's "Merger Moratorium Act" prohibits an Ohio corporation from engaging
in specified transactions such as mergers, certain asset sales, certain
issuances of shares, a liquidation or the like with a beneficial owner of 10% or
more of the outstanding voting power of the corporation during the three-year
period following the date the person became the owner of the 10% interest,
unless prior to such date the transaction or the acquisition of shares was
approved by the directors of the corporation. After the three-year period, such
transactions may be entered into if approved by the holders of at least
two-thirds of the voting power of the corporation (including by the holders of
at least a majority of the shares held by persons other than an interested
person, as defined in the statute) or if the consideration to be paid in the
transaction is at least equal to certain specified amounts.

     The Underwriting Agreement provides that the several Underwriters are
obligated to purchase all of the Notes offered hereby, if any are purchased. The

a concession of not in excess of 1.80% of the principal amount of the Notes to
certain dealers, including the Underwriters; that the Underwriters and such

in an aggregate principal amount proportionate to such Underwriter's initial
commitment.

market in the Notes, but they are not obligated to do so and may discontinue any
market making at any time without notice. No assurance can be given as to the

                         REPORT OF INDEPENDENT AUDITORS
 
SHAREHOLDERS AND BOARD OF DIRECTORS
ROBBINS & MYERS, INC. AND SUBSIDIARIES
 
     We have audited the accompanying consolidated balance sheet of Robbins &
Myers, Inc. and Subsidiaries as of August 31, 1995 and 1994, and the related
statements of consolidated operations and retained earnings and cash flows for
each of the three years in the period ended August 31, 1995. 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 financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Robbins &
Myers, Inc. and Subsidiaries at August 31, 1995 and 1994, and the consolidated
results of their operations and their cash flows for each of the three years in
the period ended August 31, 1995, in conformity with generally accepted
accounting principles.
 
     As discussed in the Summary of Accounting Policies note to the Consolidated
Financial Statements, in 1993 the Company changed its method of accounting for
postretirement benefits other than pensions and accounting for income taxes.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
     (INFORMATION PERTAINING TO MAY 31, 1996 AND FOR THE NINE MONTHS ENDED
                           MAY 31, 1996 IS UNAUDITED)
 
SUMMARY OF ACCOUNTING POLICIES
 
CONSOLIDATION
 
     The consolidated financial statements include accounts of the Company and
its wholly-owned subsidiaries. All significant inter-company accounts and
transactions have been eliminated upon consolidation. All of the Company's
operations are conducted in the fluids management industry.
 
INCOME TAXES
 
     Income taxes are provided for all items included in the Statement of
Consolidated Operations and Retained Earnings regardless of the period when such
items are reported for income tax purposes. Deferred income taxes reflect the
net effects of temporary differences between the carrying amounts of assets and
liabilities for financial reporting purposes and the amounts used for income tax
purposes.
 
PROPERTY, PLANT AND EQUIPMENT, NET
 
     Property, plant and equipment are stated at cost. Depreciation expense is
recorded over the estimated useful life of the asset on the straight-line method
using the following lives:
 
<TABLE>
        <S>                                                             <C>
        Land improvements............................................         20 years
        Buildings....................................................         40 years
        Machinery & equipment........................................    3 to 15 years
</TABLE>
 
     The Company's normal policy is to charge repairs and improvements made to
capital assets to expense as incurred. In limited circumstances, major building
repairs are capitalized and amortized over the estimated life of the new asset
and any remaining value of the old asset is written off. Repairs to machinery
and equipment must result in an addition to the useful life of the asset before
the costs are capitalized.
 
     "Property, Plant and Equipment, Net" consisted of the following:

GOODWILL AND OTHER INTANGIBLE ASSETS
 
Goodwill is the excess of the purchase price paid over the value of net assets
of businesses acquired. Amortization of goodwill is calculated on a
straight-line basis over 40 years. The carrying value of goodwill is reviewed
quarterly if the facts and circumstances suggest that it may be permanently
impaired. If the review indicates that goodwill will not be recoverable, as
determined by the undiscounted cash flow method, the asset will be reduced to
its estimated recoverable value. Accumulated amortization of goodwill and other
intangible assets totaled $3,904,000 and $1,176,000 at August 31, 1994 and 1995,
respectively.
 
     At August 31, "Other Intangible Assets" consisted of the following:

INCOME PER SHARE
 
     All income per share amounts are based on the weighted average number of
shares outstanding during the year plus the dilutive effect of common stock
equivalents. The stock appreciation rights granted in connection with the prior
year acquisitions of Pfaudler, Chemineer and Edlon have been excluded from the
calculation of income per share. See the Common Stock note for additional
information.

RESEARCH AND DEVELOPMENT
 
     Research and development expenditures are expensed as incurred and amounted
to approximately $2,403,000, $1,363,000 and $1,260,000 for the years ended
August 31, 1995, 1994 and 1993, respectively.
 
ACCOUNTS RECEIVABLE
 
     Accounts receivable are stated net of allowances for doubtful accounts
totaling $1,260,000 and $952,000 at August 31, 1995 and 1994, respectively.
Accounts receivable relate primarily to customers located in North America and
Western Europe and are concentrated in the specialty chemicals, pharmaceuticals
and oil and gas recovery industries. To reduce credit risk, the Company performs
credit investigations prior to accepting an order and when necessary, requires
advance payments and letters of credit to insure payment.
 
STATEMENT OF CONSOLIDATED CASH FLOWS
 
     Cash and cash equivalents consist of working cash balances and temporary
investments having an original maturity of 90 days or less.
 
CHANGES IN ACCOUNTING POLICIES
 
     In 1993, the Company adopted Statement of Financial Accounting Standards
No. 106, "Employers Accounting for Postretirement Benefits Other Than Pensions"
and No. 109, "Accounting for Income Taxes."
 
     Statement No. 106 generally requires the accrual of the expected costs of
postretirement benefits by the date the employees become eligible for benefits.
Previously, the expense for these benefits was recognized as claims were paid. A
charge of $8,812,000, net of income taxes of $5,239,000, was recognized as the
cumulative effect for the adoption of Statement No. 106.
 
     Statement No. 109 replaces Statement No. 96 and the Company will continue
using the liability method of computing deferred income taxes. A credit of
$794,000 was recognized as the cumulative effect for the adoption of Statement
No. 109.
 
EQUITY INVESTMENTS
 
     The Company owns 40% of Gujarat Machinery Manufacturers, Ltd. (GMM). GMM is
located in India and manufactures and markets glass-lined reactor and storage
vessels, parts and services, primarily for the Indian market. In addition, the
Company owns 50% of Universal Glasteel Equipment (UGE) located in Robbinsville,
New Jersey. UGE is a supplier of used and reconditioned glass-lined storage and
reactor vessels. The Company uses the equity method of accounting for the
investments, totaling approximately $2,980,000, which are included in "Other
Assets" in the Consolidated Balance Sheet.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The following methods and assumptions were used by the Company in
estimating the fair value of financial instruments:

          Current portion long-term debt and equity investments. -- The amounts
     reported approximate the market value of similar instruments.
 
          Long-term debt. -- The amounts reported are consistent with the terms,
     interest rates and maturities currently available to the Company for
     similar debt instruments.
 
          Interest swap agreements. -- The amounts reported are consistent with
     values at which they could be settled, based upon dealer estimates.
 
          Foreign exchange contracts. -- The amounts reported are estimated
     using quoted market prices for similar instruments.
 
FOREIGN CURRENCY ACCOUNTING
 
     Gains and losses resulting from the settlement of a transaction in a
currency different from that used to record the transaction are charged or
credited to operations when incurred. Adjustments resulting from the translation
of foreign financial statements into U.S. dollars are recognized as a separate
component of shareholders' equity for all foreign units except those located in
Brazil. The U.S. dollar is the functional currency for the Brazilian units. As a
result, translation gains and losses for these operations are reflected in net
income.
 
RECOGNITION OF REVENUE
 
     Revenue is primarily recognized as products are shipped to customers except
for infrequent long-term contracts for which revenue is recognized under the
percentage of completion method. At August 31, 1995, 1994 and 1993 there were no
such contracts in process.
 
PRODUCT WARRANTY
 
     Provision for product warranty is recognized as a liability at the time of
sale based on the historical relationship of warranty expense to sales. Actual
payments of warranty claims are charged against the liability as incurred. The
liability is reviewed quarterly and adjusted as necessary.
 
COMMON STOCK
 
     The Company's stock option plans provide for the granting of options to
directors, officers and other key employees. Under the plans, the option price
per share may not be less than the fair market value as of the date of grant and
the options become exercisable on a vesting schedule determined by the
Compensation Committee of the Board of Directors. Most currently outstanding
grants become exercisable over a three or four year period. Proceeds from the
sale of stock issued under option arrangements are credited to common stock. The
Company makes no charges or credits against earnings with respect to options.
 
     At August 31, 1995 and 1994, 882,500 and 2,800,000 shares, respectively,
were reserved for future grants.

     The Company also sponsors a long-term incentive stock plan for senior
executives. Under the program, participants earn performance shares based on a
three year measurement of how favorably the total return on Company shares
compares to the total shareholder return of the Russell 2000 Company Group. No
performance shares are earned unless the total return on Company shares is at
least equal to the median return for companies included in the Russell 2000.
Performance shares earned under the program are issued to the participants at
the end of the three year measurement period and are subject to forfeit if the
participant leaves the employment of the Company within the next two years.
 
     At August 31, 1995, 73,000 units had been awarded under the program. The
Company has estimated the total value of shares that could be earned under the
program and has chosen to recognize the cost ratably over a five year period.
The amount charged to expense for this program is $562,000 as of August 31,
1995.
 
     During 1994, in connection with the acquisition of Pfaudler, Chemineer and
Edlon, the Company issued to the seller stock appreciation rights on 4,000,000
shares of its common stock. The stock appreciation rights entitle the holder to
receive a payment equal to the increase in market value of the Company's common
stock above $11.50 per share to a maximum market value of $20 per share. The
stock appreciation rights are exercisable by the holder during the period
January 1, 1995 through June 30, 2000. At the Company's option, payment may be
made in cash or common stock of the Company. It is the Company's intention to
make any payment for stock appreciation rights in cash and therefore the payment
will result in additional goodwill at the time of the transaction. See SAR
Redemption note for additional information.
 
     The net changes in common shares outstanding during 1995, 1994 and 1993
were increases of 119,454, 89,140 and 9,994 shares, respectively. Activity for
all years was limited to employee transactions.
 
RETIREMENT PLANS
 
     The Company sponsors three defined contribution plans covering most
salaried employees and certain domestic hourly employees. Company contributions
are made to the plans based on a percentage of eligible amounts contributed by
participating employees.
 
     The Company also has several defined benefit plans covering all domestic
employees and certain foreign employees. Plans covering salaried employees
provide benefits based on years of service and employees' compensation. Plans
covering hourly employees generally provide benefits of stated amounts for each
year of service. The Company's funding policy is consistent with the funding
requirements of applicable federal regulations. At August 31, 1995 and 1994
pension assets were invested in short and long-term interest bearing obligations
and equity securities, including 238,000 shares of the Company's common stock.

     During 1995, the Company adjusted its minimum pension liability to
$4,016,000 from $4,109,000 in the prior year. This liability is required for
defined benefit plans whose accumulated benefits exceed assets. The transaction,
which had no effect on income, was recorded by adjusting an intangible asset to
the amount of $3,242,000 from $3,708,000 in 1994 and adjusting equity by
$373,000 for a total equity adjustment of $774,000 at August 31, 1995.

     The projected benefit obligation was determined using a discount rate of 7%
in 1995 (7 1/2% in 1994) and weighted average pay increases of 6 3/4%. The
assumed long-term rate of return on plan assets is 9 1/2% in 1995, 10% in 1994
and 10 1/2% in 1993. The effect of the change in the discount rate on the above
plans is an increase in the projected benefit obligation of approximately
$3,011,000.

     Income taxes paid in 1995, 1994 and 1993 were $3,007,000, $3,299,000 and
$2,808,000, respectively. The Company also has a Canadian tax loss carryforward
of approximately $900,000 and a German tax loss carryforward of $2,600,000 for
corporation tax purposes and $6,700,000 for trade tax purposes. For financial
reporting purposes, a valuation allowance was deducted for a portion of the
deferred tax benefit related to the German tax loss carryforwards. The Canadian
carryforward, if unused, will expire in future years beginning in 1998. The
German carryforward has no expiration period.
 
     At August 31, 1995, the Company has a capital loss carryforward of
$3,077,000 for income tax purposes that expires in the years ending August 31,
1997 through August 31, 1999.
 
     The carryforward was primarily generated from the disposal of the Motion
Control Group in 1991. For financial reporting purposes, a valuation allowance
was deducted for the full amount of the deferred tax benefit related to this
carryforward.

recorded for this purpose in 1994 or 1993. The amount of undistributed retained
earnings is $3,339,000 and $977,000 at August 31, 1995 and 1994.

     At August 31, 1995, the Company had senior debt outstanding under an
agreement with two Ohio banks. The agreement consists of a term loan and a
revolving credit arrangement. The term loan portion of the agreement is payable
in quarterly installments through 2001. During 1995, the Company amended the
revolving credit portion of the agreement and increased the amount the Company
can borrow by $15 million to $50 million. The revolving credit agreement does
not require compensating balances; however, a nominal commitment fee is paid on
the unused portion.
 
     The interest rate on both the term loan and any outstanding balance under
the revolving credit portion of the agreement is variable based upon Prime or a
formula tied to LIBOR rates. At

August 31, 1995, the interest rate for all amounts outstanding ranged from
7 1/2% to 8 1/3% (6 1/3% to 8 1/3% at August 31, 1994). During 1994, the Company
entered into interest rate swap agreements to manage its exposure to
fluctuations in short-term interest rates. These arrangements total $25 million,
expire in 1997 and allow the Company to pay an effective interest rate of
approximately 8 1/3%. The counter party to the transaction is one of the loan
originating banks and the Company continually monitors its financial position
and credit rating to guard against credit risk.
 
     The senior debt agreement is secured by all domestic assets except land and
buildings and includes certain restrictive covenants which include, among other
things, minimum requirements for tangible net worth, working capital, additional
debt, debt service coverage and payment of cash dividends. At August 31, 1995,
$5,789,000 of retained earnings is available for future dividends. See SAR
redemption note.
 
     On March 1, 1996, the Company incurred subordinated debt and recorded
additional goodwill of $1.6 million to record contingent purchase price
provisions related to the Pharaoh acquisition.
 
     At August 31, 1994, subordinated debt consisted of $50 million principal
amount. During the third quarter of 1995, the Company recorded an extraordinary
gain of $2,183,000 ($1,332,000 after taxes or $.12 per share) in connection with
the early retirement of $25 million of the subordinated debt. The remaining
principal amount of $25 million bears interest at 5 1/2% but has been discounted
to reflect a rate of 9 1/4% which approximated the market interest rate on debt
instruments with similar features at the time the debt was incurred. The debt
becomes due on June 30, 1998, and the agreement includes certain restrictive
covenants which are generally consistent with, but less restrictive than, those
of the senior debt. Subject to covenant compliance, the Company may extend the
maturity of the notes until June 30, 2001, by paying an interest rate consistent
with the market rate paid on similar instruments as of the date of the maturity
extension. The debt is unsecured. It is the Company's current intention to avail
itself of the renewal option as of June 30, 1998. During 1995, the Company
incurred additional subordinated debt in the amount of $5,495,000. This debt
bears interest at 8% but has been discounted to reflect a rate of 11% which
approximated the market interest rate on debt instruments with similar features
at the time the debt was incurred. The debt is payable in annual installments on
February 28 of each year through 1999. The debt is secured by all domestic
assets of the Company.
 
     Aggregate principal payments for the debt for the five years subsequent to
August 31, 1995 are as follows:

BUSINESS ACQUISITIONS
 
     On March 1, 1995, the Company acquired Cannon Process Equipment Limited and
Pharaoh Corporation for cash and subordinated notes totaling $12,898,000.
Cannon, located in Bilston, England, sells new and reconditioned glass-lined
reactor vessels. Pharaoh, located in Rochester, New York, is a supplier of
replacement parts and services for glass-lined process equipment. At the same
time, the Company entered into a partnership with a major supplier of used
process equipment to supply used and reconditioned glass-lined vessels
worldwide. The new business units will be combined with similar activities of
Pfaudler.
 
     On June 30, 1994, the Company completed the acquisition of the Pfaudler,
Chemineer and Edlon business units for approximately $117,045,000. Pfaudler is
the foremost worldwide manufacturer of glass-lined steel chemical reactor and
storage vessels. Chemineer is a leading producer of industrial mixing and
agitation equipment and Edlon designs and fabricates engineered Teflon(R)
products and coatings. The funds used for the acquisition were provided by a
combination of cash on hand, bank debt of $52,000,000 and subordinated notes of
$43,576,000, net of discount, issued to the seller. In addition to cash and
subordinated notes, the seller also received certain stock appreciation rights
as further described in the Common Stock note.
 
     The acquisitions were accounted for under the purchase method and,
accordingly, the purchase price was allocated to the assets acquired and
liabilities assumed based on their fair values on the dates of the respective
transactions. These transactions resulted in goodwill of $71,225,000.
 
     The operating results of the acquired businesses have been included in
consolidated operating results since the dates of each acquisition. The
following unaudited pro forma summary presents the results of operations of the
Company combined with the results of Pfaudler, Chemineer and Edlon as if the
acquisition of the business units had occurred at the beginning of 1993. In
preparing the pro forma data, certain adjustments have been made to historic
operating results, including increased interest expense resulting from the new
debt structure, amortization of intangible assets and the related income tax
effects. The pro forma data exclude business restructure provisions recorded at
Pfaudler of $8,100,000 and $1,318,000 in 1994 and 1993, respectively. This

     During 1995 the Company continued the implementation of an extensive
restructuring program at Pfaudler which was in process at the time of the
acquisition in fiscal 1994. Included in the program is a major reorganization of
the German facility, which includes employee termination costs. In addition,
Pfaudler has completed the curtailment of new product manufacturing in Mexico.

     The consolidation of the Company's industrial mixer production, announced
last year, is in process and will be completed during the first half of fiscal
1996. The program involves closing the existing Prochem manufacturing facility
in Brampton, Ontario and relocating all business activities to the Chemineer
facility in Dayton, Ohio. The move has been delayed approximately six months
from the original timetable due to an ongoing systems implementation project at
Chemineer and the need to complete a building addition to accommodate additional
production.
 
     Finally, the move of the RKL valve production from a facility in Lumberton,
New Jersey to the Company's pump manufacturing plant in Springfield, Ohio was
completed during fiscal 1995 as originally planned.
 
     At August 31, 1995, the Company believes the above reserve is adequate to
complete the various programs currently in process. The Company continually
monitors charges against the reserve and has made adjustments as required.
 
SAR REDEMPTION
 
     On October 10, 1995, 3,700,000 of the stock appreciation rights which were
issued in connection with the acquisition of Pfaudler, Chemineer and Edlon (see
Common Stock note) were retired for $4.875 per right. This resulted in a total
payment of $18,037,500. The payment was made October 24, 1995. The payment was
financed through the Company's long-term revolving credit agreement. The
Company's covenants with its lenders have been amended as a result of this
transaction and the Company is in compliance with the modified covenants.
 
STOCK SPLIT
 
     At the June 26, 1996, Board of Directors' meeting the Board approved a
2-for-1 stock split for shareholders of record on July 12, 1996, effected in the
form of a share distribution on July 31, 1996. Per share information has been
adjusted to reflect the effect of this stock split for all periods presented.
 
ACCOUNTING FOR STOCK BASED COMPENSATION
 
     In October 1995, the Financial Accounting Standards Board issued Statement
No. 123, "Accounting for Stock-Based Compensation." The Statement establishes
financial accounting and reporting standards for stock-based employee
compensation plans. Companies may elect to account for such plans under the fair
value method or continue the previous accounting and disclose pro forma net
income and earnings per share as if the fair value method was applied. The
statement is to be applied on a prospective basis beginning in the Company's
fiscal year 1997.
 
     The Company has not as yet determined the potential financial statement
impact of the Standard, nor has it decided how or when it will initially adopt
the Standard.
