OFFER FOR ALL OUTSTANDING 11 1/8% SERIES B SENIOR SUBORDINATED NOTES DUE 2007
IN EXCHANGE FOR 11 1/8% SERIES A SENIOR SUBORDINATED NOTES DUE 2007 OF
 
NEENAH CORPORATION
 
THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M.,
NEW YORK CITY TIME ON                , 1997 UNLESS EXTENDED
 
NEENAH CORPORATION, a Wisconsin corporation (the "Company"), hereby offers to
exchange an aggregate principal amount of up to $150,000,000 of its 11 1/8%
Senior Subordinated Notes due 2007 (the "New Notes") for a like principal amount
of its 11 1/8% Senior Subordinated Notes due 2007 (the "Old Notes") outstanding
on the date hereof upon the terms and subject to the conditions set forth in
this Prospectus and in the accompanying Letter of Transmittal (which together
constitute the "Exchange Offer"). The New Notes and the Old Notes are
collectively hereafter referred to as the "Notes." The terms of the New Notes
are identical in all material respects to those of the Old Notes, except for
certain transfer restrictions and registration rights relating to the Old Notes.
The New Notes will be issued pursuant to, and entitled to the benefits of, the
Indenture (as defined) governing the Old Notes. The New Notes will be unsecured
and will be subordinated to all existing and future Senior Indebtedness (as
defined) of the Company. The New Notes will rank pari passu with any future
Senior Subordinated Indebtedness (as defined) of the Company and will rank
senior to all subordinated indebtedness of the Company. The New Notes will be
fully guaranteed (the "Subsidiary Guaranties") by each of the Company's
principal operating subsidiaries, Neenah Foundry Company ("Neenah Foundry"),
Hartley Controls Corporation ("Hartley Controls"), and Neenah Transport, Inc.
("Neenah Transport") (collectively, the "Guarantor Subsidiaries"). The Company
is a holding company that will derive substantially all of its operating income
and cash flow from its subsidiaries. The Guarantor Subsidiaries guarantee the
Senior Bank Facilities (as defined) and are jointly and severally liable on a
senior basis with the Company for all obligations thereunder. Such obligations
are secured by pledges of all the capital stock of the Guarantor Subsidiaries
and security interests in, or liens on, substantially all other tangible and
intangible assets located in the United States of the Guarantor Subsidiaries.
See "Description of Senior Bank Facilities" and "Description of Notes."
 
The New Notes are being offered hereunder in order to satisfy certain
obligations of the Company and the Guarantor Subsidiaries contained in the
Exchange and Registration Rights Agreement dated April 30, 1997 (the
"Registration Rights Agreement"), among the Company, the Guarantor Subsidiaries
and Chase Securities Inc. and Morgan Stanley & Co. Incorporated (the "Initial
Purchasers"), with respect to the initial sale of the Old Notes.
 
The Company will not receive any proceeds from the Exchange Offer. The Company
will pay all the expenses incident to the Exchange Offer. Tenders of Old Notes
pursuant to the Exchange Offer may be withdrawn at any time prior to the
Expiration Date (as defined) for the Exchange Offer. In the event the Company
terminates the Exchange Offer and does not accept for exchange any Old Notes
with respect to the Exchange Offer, the Company will promptly return such Old
Notes to the holders thereof. See "The Exchange Offer."
 
Each broker-dealer that receives New Notes for its own account pursuant to the
Exchange Offer must acknowledge that it will deliver a prospectus in connection
with any resale of such New Notes. The Letter of Transmittal states that by so
acknowledging and by delivery of a prospectus, a broker-dealer will not be
deemed to admit that it is an "underwriter" within the meaning of the Securities
Act of 1933, as amended (the "Securities Act"). This Prospectus, as it may be
amended or supplemented from time to time may be used by a broker-dealer in
connection with resales of New Notes received in exchange for Old Notes where
such Old Notes were acquired by such broker-dealer as a result of market-making
activities or other trading activities. Each of the Company and the Guarantor
Subsidiaries has agreed that, for a period of 180 days after the Expiration
Date, it will make this Prospectus available to any broker-dealer for use in
connection with any such resale. See "Plan of Distribution."
 
- --------------------------------------------------------------------------------
 
Prior to the Exchange Offer, there has been no public market for the Old Notes.
If a market for the New Notes should develop, such New Notes could trade at a
discount from their principal amount. The Company currently does not intend to
list the New Notes on any securities exchange or to seek approval for quotation
through any automated quotation system and no active public market for the New
Notes is currently anticipated. There can be no assurance that any public market
for the New Notes will develop.
 
The Exchange Offer is not conditioned upon any minimum principal amount of Old
Notes being tendered for exchange pursuant to the Exchange Offer.
 
SEE "RISK FACTORS" COMMENCING ON PAGE 14 FOR A DISCUSSION OF CERTAIN FACTORS
THAT HOLDERS OF OLD NOTES SHOULD CONSIDER IN CONNECTION WITH THE EXCHANGE OFFER.

                                  THE COMPANY
 
OVERVIEW
 
     The Company, founded in 1872, is one of the largest manufacturers of a wide
range of high quality ductile and gray iron castings for the heavy municipal
market and selected segments of the industrial market. The Company believes it
is the largest manufacturer of heavy municipal iron castings in the United
States with approximately a 19% market share in calendar year 1996. The
Company's broad range of heavy municipal iron castings includes manhole covers
and frames, storm sewer frames and grates, heavy duty airport castings,
specialized trench drain castings, specialty flood control castings and
ornamental tree grates. These municipal castings are sold throughout the United
States to state and local government entities, utility companies, precast
concrete manhole structure producers and contractors for both new construction
and infrastructure replacement. The municipal market generated approximately 43%
of the Company's 1997 net sales. The Company believes it is also a leading
manufacturer of a wide range of complex industrial castings, including castings
for medium- and heavy-duty truck drive line components, a broad range of
castings for the farm equipment industry and specific components for compressors
used in heating, ventilation and air conditioning systems ("HVAC"). The
industrial market generated approximately 53% of the Company's 1997 net sales.
In addition, the Company engineers, manufactures and sells customized sand
control systems and related products, which are an essential part of the casting
process, to other iron foundries. Sales of these sand control systems and
related products represented approximately 4% of the Company's 1997 net sales.
 
     The Company currently operates two modern foundries with an annual
aggregate rated capacity of approximately 187,000 tons at a single site in
Neenah, Wisconsin. Since 1985, the Company has invested approximately $100
million in its production facilities, with approximately $73 million invested in
a major plant modernization program from 1985 to 1990. This plant modernization
program was a critical part of a long-term strategy to produce higher volume,
value-added castings for its existing industrial customers and to penetrate
other selected segments of the industrial market, while preserving its position
as the leader in the heavy municipal market. This modernization program entailed
the closing of the Company's oldest foundry, Plant 1, and the updating of the
Company's other two foundries, Plants 2 and 3, which enabled the Company both to
produce higher volume, complex castings for selected industrial segments and to
improve the Company's cost position in the heavy municipal market. Following the
completion of the modernization program, the Company has steadily decreased its
production of lower margin products such as axle covers and brake drums and
increased the production of higher margin, more complex parts such as
transmission and axle housings. As a result of this strategy, the Company's
ongoing improvements in its manufacturing process and increased demand for
medium- and heavy-duty truck components,
 
                                        3
   7
 
net sales and EBITDA (as defined) have increased substantially. From 1992 to
1997, net sales have grown from $116.5 million to $165.4 million, representing a
compound annual growth rate of 7.3%, and EBITDA has grown from $13.4 million to
$38.0 million during the same period, representing a compound annual growth rate
of 23.2%.
 
COMPETITIVE ADVANTAGES
 
     The Company believes it benefits from the following competitive advantages,
which have enabled it to increase sales and operating profitability and to
maintain its position as one of the leaders in the iron casting industry.
 
     Leading Market Position.  The Company believes it is the largest
manufacturer of heavy municipal iron castings in the United States with
approximately a 19% market share in calendar year 1996. Furthermore, the
Company, which has produced municipal castings for over 70 years has, according
to its estimates, over a 50% market share in nine of the top ten states in which
the Company sells heavy municipal castings. Sales in those states represented
approximately 69% of the Company's municipal sales in 1997. The Company believes
it is also one of the largest manufacturers of iron castings for selected
segments of the industrial market, including the medium-and heavy-duty truck and
farm equipment segments. The Company is the sole sourced supplier for over 85%
of the industrial products it produces and has multi-year arrangements with
certain of its largest customers. The Company believes it can continue to
capitalize on its strong market position to generate additional revenues and
realize economies of scale, thereby increasing margins and earnings.
 
     Low Cost Structure.  As a result of its size, significant investment in
equipment and technology and focus on improving efficiency, the Company believes
it possesses a highly competitive cost structure. Since 1985, the Company has
invested approximately $100 million in its production facilities, with
approximately $73 million invested in plant modernization and new equipment from
1985 to 1990. These investments, combined with the Company's ongoing
improvements to its manufacturing process, have substantially increased
efficiency and manufacturing productivity. From 1992 to 1997, the Company
reduced its scrap rate from 3.5% to 2.0%, which the Company believes is one of
the lowest scrap rates in the industry. During the same period, the Company
reduced its employee hours per ton by approximately 40% from 14.8 to 9.0, while
improving product quality levels and producing higher margin, more complex
parts.
 
     Broad Product Offering.  The Company carries a broad range of products,
offering more than 4,400 patterns that can produce over 20,000 part combinations
for the heavy municipal market, and more than 350 patterns for the industrial
market. The Company believes its municipal catalog offers the largest castings
selection of any foundry serving the heavy municipal market. This extensive
product offering, which includes hundreds of one-of-a-kind specialty items,
enables the Company to compete throughout the United States and provide a
substantial number of the many types of municipal castings required for
individual projects. Heavy municipal castings are manufactured from
Company-owned patterns which have been appraised by independent appraisers to be
in excess of $22 million. Additionally, the Company's extensive and growing
offering of complex industrial castings enables it to more effectively service
its customers' increasing needs for highly engineered cast parts and often
positions the Company as the sole source of supply to original equipment
manufacturers ("OEMs") and their first tier suppliers. The Company's broad
industrial product offering and its recognized casting engineering expertise
have become increasingly important as large industrial customers seek to reduce
the number of suppliers with whom they conduct business.
 
     Strong, Diverse Customer Relationships.  The Company continually focuses on
establishing and maintaining strong relationships with its customers. In the
heavy municipal market, the Company currently sells to over 17,000 active
customers in all 50 states, with the majority of its sales concentrated in the
midwestern states. The Company believes it has the largest sales and marketing
 
                                        4
   8
 
effort of any foundry serving the heavy municipal market, including 47 Company
employees and 26 commissioned representatives. The Company believes the size of
its marketing effort, the breadth of its product offering and the level of its
technical support provide it with a significant competitive advantage and will
allow it to further strengthen its leading position in the heavy municipal
market. With respect to the industrial market, the Company has established
strong relationships with leading manufacturers of medium- and heavy-duty truck
components, farm equipment and HVAC systems. The Company is the sole sourced
provider for over 85% of the products it currently supplies to its industrial
customer base and has multi-year arrangements with certain of its largest
customers. Furthermore, the average industrial casting typically takes between
12 and 18 months to go from the design phase to full production and has an
average life cycle of approximately 8 to 10 years. This lengthy development
process, in which the Company actively participates, provides the Company with
an inventory of products that cannot be quickly replicated by its competitors.
Historically, the foundry that has originally manufactured an industrial part
has continued to manufacture that part throughout its product life cycle. The
Company's participation in both the heavy municipal and industrial markets helps
to diversify the Company's business and to reduce the Company's reliance on
individual customers or end-use markets.
 
     High Quality Products and Customer Service.  The Company believes it enjoys
a reputation for providing a high level of customer service and is recognized
for its ability to consistently manufacture high-quality, complex products. The
Company believes its manufacturing capabilities and process controls allow it to
manufacture high quality castings which are dimensionally and metallurgically
consistent. In addition to providing high quality products, the Company
emphasizes customer service by providing tooling and engineering development
support to its customers, consistent on-time delivery utilizing its own fleet of
trucks for delivery of many of its municipal products and a small portion of the
Company's industrial products and follow-up through its sales and marketing
team. The Company believes its ability to provide such product quality and
responsive service has fostered customer loyalty and long-term relationships.
 
     Experienced Management Team with Significant Equity Stake.  The top seven
members of the Company's senior operating management have an average of
approximately 12 years with the Company and 23 years in the iron foundry
industry. Certain members of the Company's management (the "Management
Investors") beneficially own, on a fully diluted basis, approximately 10% of the
common stock of the Company.
 
BUSINESS STRATEGY
 
     The Company's strategy for achieving continued growth in sales and
profitability includes: (i) increasing the sale of higher margin products, (ii)
selectively entering new markets, (iii) improving operating performance and (iv)
making selective acquisitions.
 
     Increasing the Sale of Higher Margin Products.  The Company continually
strives to improve the margins on the parts it produces. In the heavy municipal
market, the Company has historically maintained strong margins by periodically
implementing price increases and introducing new, higher value-added products.
For example, the Company is currently leading the market in the sale of
lightweighted municipal castings, which are less costly to handle and require
less raw material to produce. The Company believes incremental margin
improvements will be realized from the Company's increased production of these
lightweighted products. In the industrial market, the Company increased its
focus on manufacturing complex, highly engineered castings in the early 1990s
following substantial capital investment in the late 1980s. Since 1991, the
Company has steadily increased the volume, array and complexity of the parts it
produces for its industrial customers. The Company intends to continue to pursue
opportunities to produce more complex, higher value-added castings, thereby
continuing to improve product margins.
 
     Selectively Entering New Markets.  The Company intends to selectively
expand its presence in both the heavy municipal and industrial markets. In the
heavy municipal market, the Company is
 
                                        5
   9
 
considering expanding its product offering in high volume markets such as New
York and Nevada where the Company already has sales representatives in place and
for which the Company has already invested in certain of the toolings necessary
to meet potential product demand. In addition, the Company is exploring further
opportunities in New Jersey, New Hampshire and Massachusetts. The Company's
strategy in its chosen industrial segments is to continue to increase its
penetration of existing customers and to develop similar relationships with
other selected industrial companies which would value the Company's technical
ability and high level of product quality and customer service. The Company also
intends to explore opportunities in austempering (heat-treating ductile iron)
and machining and assembling sub-components for specific industrial customers.
 
     Improving Operating Performance.  The Company operates two modern
foundries, and believes it possesses a highly competitive cost structure. The
Company intends to continue to seek ways to capitalize on and extend its
technological expertise and operating efficiencies, thereby reducing its
operating costs. In contrast to the major investments made from 1985 to 1990,
which significantly improved both manufacturing capacity and efficiency, the
Company's near term capital expenditures will be focused primarily on
incrementally improving efficiency and reducing costs through projects such as:
(i) sand system optimization, (ii) material handling improvements and (iii)
energy utilization improvements.
 
     Making Selective Acquisitions.  The United States iron foundry industry is
highly fragmented despite significant consolidation over the past decade. In
1986, there were approximately 880 foundries engaged in the casting of iron,
with an aggregate capacity of approximately 15 million tons according to
Stratecasts, Inc., a foundry industry research and consulting organization. By
1996, the number of iron foundries decreased to approximately 730, with an
aggregate capacity of approximately 13 million tons. Management believes the
consolidation that has occurred will continue, particularly in the industrial
market, as technical, environmental and quality standards continue to increase.
The Company intends to pursue selective acquisition opportunities that
complement its existing product offering or enable the Company to expand its
presence in selected geographic areas of the heavy municipal market. The Company
believes such acquisitions will provide opportunities for incremental revenue
and cash flow by leveraging the Company's current expertise in manufacturing,
sales and marketing, and product and process engineering.
 
                                   THE MERGER
 
     NFC Castings, Inc. ("Holdings") and its wholly-owned subsidiary, NC Merger
Company ("NC Merger"), were organized by Citicorp Venture Capital, Ltd. ("CVC")
and its affiliate, ACP Holding Company, to effect the acquisition of the
Company. On April 30, 1997, pursuant to an Agreement and Plan of Reorganization,
dated November 20, 1996, as amended (the "Merger Agreement"), among Holdings, NC
Merger and the Company, NC Merger merged with and into the Company, with the
Company as the surviving corporation (the "Merger"). Holdings is a wholly-owned
subsidiary of ACP Holding Company ("ACP Holdings"). ACP Holdings is wholly-owned
by ACP Products, L.L.C., which in turn is owned in part by CVC and certain other
investors (collectively, the "Investor Group"). The Management Investors also
own an interest in ACP Products, L.L.C.
 
     The consideration for the Merger was $236.9 million in cash (the "Merger
Consideration"), subject to a closing date net worth adjustment. Upon
consummation of the Merger, the Company paid $11.3 million to certain former
stockholders of the Company (the "Former Stockholder Payment" and, together with
the Merger Consideration, the "Merger Price"). Pro forma for a March 31, 1997
closing, the closing date net worth adjustment would have been $9.1 million
which would result in a total pro forma Merger Price of $258.3 million
(including acquisition costs of $1.0 million). The Merger Price reflects the use
of approximately $25.3 million of cash on the Company's balance sheet pro forma
for a March 31, 1997 closing (resulting in a valuation of the Company's business
and other assets of approximately $233.0 million). In order to finance the
Merger Price, including the payment of related fees and expenses: (i) NC Merger
consummated the Offering;
 
                                        6
   10
 
(ii) NC Merger entered into a credit agreement providing for (a) a term loan
(the "Tranche A Term Loan") in the amount of $20.0 million and a second term
loan (the "Tranche B Term Loan" and, together with the Tranche A Term Loan, the
"Term Loans") in the amount of $25.0 million, and (b) a revolving credit
facility (the "Revolving Credit Facility" and, together with the Term Loans, the
"Senior Bank Facilities") in the amount of $30.0 million, subject to a borrowing
base formula; (iii) Holdings made an equity contribution (the "Equity
Contribution") of $45.0 million to NC Merger; and (iv) $25.3 million of cash
(pro forma for a March 31, 1997 closing) was utilized. Concurrently with the
consummation of the Offering, the Company, as the surviving corporation in the
Merger, assumed, pursuant to the Merger, the obligations under the Notes and the
Senior Bank Facilities. The Offering, the establishment of the Senior Bank
Facilities, the Equity Contribution and the Merger are referred to collectively
herein as the "Transactions."
 
     The sources and uses of funds for the Merger and related Transactions,
assuming that the Merger occurred on March 31, 1997, were as follows (dollars in

      CONSEQUENCES OF EXCHANGING OLD NOTES PURSUANT TO THE EXCHANGE OFFER
 
     Based on certain interpretive letters issued by the staff of the Commission
to third parties in unrelated transactions, the Company is of the view that
holders of Old Notes (other than any holder who is an "affiliate" of the Company
within the meaning of Rule 405 under the Securities Act) who exchange their Old
Notes for New Notes pursuant to the Exchange Offer generally may offer such New
Notes for resale, resell such New Notes and otherwise transfer such New Notes
without compliance with the registration and prospectus delivery provisions of
the Securities Act, provided such New Notes are acquired in the ordinary course
of the holders' business and such holders have no intention, or any arrangement
with any person, to participate in a distribution of such New Notes. Each
broker-dealer that receives New Notes for its own account in exchange for Old
Notes must acknowledge that it will deliver a prospectus in connection with any
resale of such New Notes. See "Plan of Distribution." In addition, to comply
with the securities laws of certain jurisdictions, if applicable, the New Notes
may not be offered for sale unless they have been registered or qualified for
sale in such jurisdiction or an exemption from registration or qualification is
available and is complied with. The Company has agreed, pursuant to the
Registration Rights Agreement and subject to certain specified limitations
therein, to register or qualify the New Notes for offer or sale under the
securities or blue sky laws of such jurisdictions as any holder of the Notes
reasonably requests in writing. If a holder of Old Notes does not exchange such
Old Notes for New Notes pursuant to the Exchange Offer, such Old Notes will
continue to be subject to the restrictions on transfer contained in the legend
thereon. In general, the Old Notes may not be offered for sale, unless
registered under the Securities Act, except pursuant to an exemption from, or in
a transaction not subject to, the Securities Act and applicable state securities
laws. Holders of Old Notes do not have any appraisal or dissenters' rights under
Delaware General Corporation Law in connection with the Exchange Offer. See "The
Exchange Offer -- Consequences of Failure to Exchange; Resales of New Notes."
 
     The Old Notes are currently eligible for trading in the Private Offerings,
Resales and Trading through Automated Linkages ("PORTAL") market. Following
commencement of the Exchange Offer but prior to its consummation, the Old Notes
may continue to be traded in the PORTAL market. Following consummation of the
Exchange Offer, the New Notes will not be eligible for PORTAL trading.
 
                                  THE OFFERING
 
     The terms of the New Notes are identical in all material respects to the
Old Notes, except for certain transfer restrictions on registration rights
relating to the Old Notes.

                             price equal to 101% of the principal amount
                             thereof, together with accrued and unpaid interest,
                             if any, to the date of purchase. See "Description
                             of Notes -- Change of Control."
 
Subsidiary Guaranties......  The New Notes will be (as are the Old Notes) fully
                             guaranteed on an unsecured, senior subordinated
                             basis by the Guarantor Subsidiaries. Neenah
                             Corporation is a holding company that derives
                             substantially all of its income from its principal
                             subsidiaries, Neenah Foundry Company, Hartley
                             Controls Corporation, and Neenah Transport, Inc.
                             The Guarantor Subsidiaries have guaranteed the
                             Senior Bank Facilities (as defined), and are
                             jointly and severally liable on a senior basis with
                             the Company for the obligations thereunder. Such
                             obligations are secured by pledges of all the
                             capital stock of the Company and the Guarantor
                             Subsidiaries and security interests in, or liens
                             on, substantially all other tangible and intangible
                             assets of the Company and the Guarantor
                             Subsidiaries. See "Description of Notes --
                             Subsidiary Guaranties" and "-- Certain Covenants
                             -- Future Note Guarantors."
 
Ranking....................  The New Notes will be (as are the Old Notes)
                             unsecured and will be subordinated to all existing
                             and future Senior Indebtedness (as defined) of the
                             Company. The New Notes will (as do the Old Notes)
                             rank pari passu with any future Senior Subordinated
                             Indebtedness of the Company and will rank senior to
                             all other subordinated indebtedness of the Company.
                             The Subsidiary Guaranties are unsecured, senior
                             subordinated obligations of the Guarantor
                             Subsidiaries, subordinated in right of payment to
                             existing and future Senior Indebtedness of the
                             Guarantor Subsidiaries. As of March 31, 1997, on a
                             pro forma basis, after giving effect to the Merger,
                             the Offering, the other Transactions, and the
                             application of the net proceeds therefrom, the
                             Company and the Guarantor Subsidiaries would have
                             had outstanding $46.0 mil-

                             (all of which is Secured Indebtedness), no Senior
                             Subordinated Indebtedness other than the
                             indebtedness represented by the Notes and no
                             indebtedness that is subordinate or junior in right
                             of repayment to the indebtedness represented by the
                             Notes.
 
Restrictive Covenants......  The indenture (the "Indenture") governing the New
                             Notes, which is the Indenture governing the Old
                             Notes, limits (i) the incurrence of additional
                             Indebtedness by the Company and its Restricted
                             Subsidiaries (as defined); (ii) the payment of
                             dividends on, and redemption of, capital stock of
                             the Company and its Restricted Subsidiaries and the
                             redemption of certain Subordinated Obligations of
                             the Company and its Restricted Subsidiaries; (iii)
                             certain other restricted payments, including
                             without limitation, investments; (iv) sales of
                             assets and Restricted Subsidiary stock; (v) certain
                             transactions with affiliates; (vi) the sale or
                             issuance of capital stock of its Restricted
                             Subsidiaries; (vii) the creation of liens; (viii)
                             the lines of business in which the Company and its

                             sale and leaseback transactions. The Indenture also
                             prohibits certain restrictions on distributions
                             from Restricted Subsidiaries. However, all of these
                             limitations and prohibitions are subject to a
                             number of important qualifications and exemptions.

                             "-- Merger and Consolidation."
 
Transfer Restrictions;
Absence of a Public Market
  for the Notes............  The New Notes are new securities and there is
                             currently no established market for the New Notes.
                             Accordingly, there can be no assurance as to the
                             development or liquidity of any market for the New
                             Notes. The Initial Purchasers have advised the
                             Company that they currently intend to make a market
                             in the New Notes. However, they are not obligated
                             to do so, and any market making with respect to the
                             New Notes may be discontinued without notice. The
                             Company does not intend to apply for listing of the
                             New Notes on any national securities exchange or
                             for their quotation through the National
                             Association of Securities Dealers Automated
                             Quotation System.

                 SUMMARY CONSOLIDATED FINANCIAL AND OTHER DATA
 
     The following table sets forth summary historical consolidated, financial
and other data of the Company for the five years ended March 31, 1997, and
certain financial and other data for the year ended March 31, 1997. The summary
historical consolidated financial and other data, (with the exception of tons
produced, employees, employee hours per ton and scrap rate) are derived from the
audited historical consolidated financial statements and the "Unaudited Pro
Forma Financial Information" of the Company, all of which are included elsewhere
in this Prospectus. The historical consolidated balance sheets for 1995, 1996
and 1997 and the historical consolidated statements of income for 1994, 1995,
1996 and 1997 were audited by Ernst & Young LLP, independent auditors. The
historical consolidated balance sheets for 1993 and 1994 and the historical
consolidated statement of income for 1993 were audited by other auditors. The
unaudited pro forma balance sheet data as of March 31, 1997 gives effect to the
Transactions as if such transactions had occurred on March 31, 1997. The
unaudited pro forma consolidated statement of income for the year ended March
31, 1997 gives effect to the Transactions as if such transactions were
consummated on April 1, 1996. The unaudited pro forma financial and other data
do not purport to represent what the Company's financial position or results of
operations would actually have been had the Transactions in fact occurred on the
assumed dates or to project the Company's financial position or results of
operations for any future date or future period. The information contained in
the following table should also be read in conjunction with "Capitalization,"
"Selected Consolidated Financial and Other Data," "Management's Discussion and
Analysis of Financial Condition and Results of Operations," "Unaudited Pro Forma
Consolidated Financial Information," and the Company's historical consolidated
financial statements and related notes included elsewhere in this Prospectus.

- ---------------
(1) Net sales for the years ended March 31, 1993 and 1994 include sales of
    products manufactured in Plant 1, which was closed in 1994 as part of the
    Company's strategy to increase its focus on higher volume, complex parts for
    its industrial customers. The majority of the parts produced in Plant 1 were
    then discontinued. Plant 1 provided sales of $30.9 million and $4.4 million
    for the fiscal years ended March 31, 1993 and 1994, respectively.
 
(2) EBITDA represents operating income plus depreciation and amortization. The
    Company has included information concerning EBITDA because management
    believes that EBITDA is generally accepted as providing useful information
    regarding a company's ability to service and/or incur debt. EBITDA should
    not be considered in isolation or as a substitute for net income, cash flows
    or other income or cash flow data prepared in accordance with generally
    accepted accounting principles or as a measure of a company's profitability
    or liquidity.
 
(3) Cash interest expense is defined as interest expense less amortization of

                                  RISK FACTORS
 
     Holders of Old Notes should carefully consider the following factors in
addition to the other information set forth in this Prospectus in connection
with the Exchange Offer. The risk factors set forth below are generally
applicable to the Old Notes as well as the New Notes.
 
SUBSTANTIAL LEVERAGE AND ABILITY TO SERVICE INDEBTEDNESS
 
     The Company is highly leveraged. As of March 31, 1997, on a pro forma
basis, after giving effect to the Merger, the Offering, the other Transactions,
and the application of the proceeds therefrom, the Company and the Guarantor
Subsidiaries would have had $46.0 million (excluding $0.6 million of outstanding
letters of credit) aggregate amount of Senior Indebtedness (all of which is
Secured Indebtedness), no Senior Subordinated Indebtedness other than that
represented by the Notes and no indebtedness that is junior in right of
repayment to the indebtedness represented by the Notes. As of March 31, 1997, on
a pro forma basis, after giving effect to the Merger, the Offering, the other
Transactions, and the application of the proceeds therefrom, as well as
borrowing base limitations and $0.6 million of outstanding letters of credit,
the Company estimates that it would have had the ability to borrow approximately
$24.8 million under the Revolving Credit Facility. Subject to the restrictions
in the Senior Bank Facilities and the Indenture, the Company may incur
additional indebtedness from time to time, including additional Senior
Indebtedness. The degree to which the Company is leveraged could have important
consequences to holders of the New Notes (and to holders of Old Notes),
including the following: (i) the Company's ability to obtain additional
financing for working capital, capital expenditures, acquisitions or general
corporate purposes may be limited; (ii) a substantial portion of the Company's
cash flow from operations must be dedicated to the payment of interest on the
New Notes (and any outstanding Old Notes), and interest and principal on the
Senior Bank Facilities and the Company's other existing indebtedness, thereby
reducing the funds available to the Company for other purposes; (iii) all of the
indebtedness under the Senior Bank Facilities will be at variable rates of
interest, which will cause the Company to be vulnerable to increases in interest
rates; (iv) all of the indebtedness outstanding under the Senior Bank Facilities
will be secured by pledges of all the capital stock of the Company and the
Guarantor Subsidiaries and security interests in, or liens on, substantially all
other assets of the Company and the Guarantor Subsidiaries, and will become due
prior to the time the principal on the Notes will become due; (v) the Company
may be hindered in its ability to adjust rapidly to changing market conditions;
and (vi) the Company's substantial degree of leverage could make it more
vulnerable in the event of a downturn in general economic conditions or in its
business.
 
     The Company's ability to pay interest on the New Notes (and any outstanding
Old Notes) and to satisfy its other debt obligations will depend on its future
operating performance, which will be affected by prevailing economic conditions
and financial, business and other factors, certain of which are beyond the
Company's control. If the Company's cash flow from operations and capital
resources is insufficient to fund its debt service obligations, the Company may
be forced to reduce or delay capital expenditures, sell assets, obtain
additional equity capital or restructure its debt. There can be no assurance
that the Company's cash flow from operations and capital resources will be
sufficient for payment of its indebtedness in the future. In the absence of such
operating results and resources, the Company could face substantial liquidity
problems and might be required to dispose of material assets or operations to
meet its debt service and other obligations, and there can be no assurance as to
the timing of such sales or the proceeds that the Company could realize
therefrom. The financial covenants and other restrictions in the Senior Bank
Facilities and the Indenture will limit the Company's ability to borrow
additional funds and dispose of certain assets. See "Description of Senior Bank
Facilities" and "Description of Notes."
 
                                       14
   18
 
SUBORDINATION; ASSET ENCUMBRANCE
 
     The payment of principal of and interest on, and any premium or other
amounts owing in respect of, the New Notes will be (as is the case with the Old
Notes) subordinated to the prior payment in full of all existing and future
Senior Indebtedness of the Company, including all amounts owing or guaranteed
under the Senior Bank Facilities. Consequently, in the event of a bankruptcy,
liquidation, dissolution, reorganization or similar proceeding with respect to
the Company, assets of the Company will be available to pay obligations of the
New Notes (and any outstanding Old Notes) only after all Senior Indebtedness of
the Company has been paid in full, and there can be no assurance that there will
be sufficient assets to pay amounts due on all or any of the New Notes (and any
outstanding Old Notes).
 
     Payments in respect of the respective Subsidiary Guaranties of the New
Notes will be (as is the case with the Old Notes) subordinated to the prior
payment in full of all existing and future Senior Indebtedness of the respective
Guarantor Subsidiaries, including all amounts guaranteed in respect of the
Senior Bank Facilities. As of March 31, 1997, on a pro forma basis after giving
effect to the Merger, the Offering, the other Transactions, and the application
of the proceeds therefrom, the aggregate principal amount of such Senior
Indebtedness would have been $46.0 million (excluding $0.6 million of
outstanding letters of credit) guaranteed under the Senior Bank Facilities.
Consequently, in the event of a bankruptcy, liquidation, dissolution,
reorganization or similar proceeding with respect to a Guarantor Subsidiary, its
assets will be available to pay obligations only after the Senior Indebtedness
of such Guarantor Subsidiary has been paid in full, and there can be no
assurance that there will be sufficient assets to pay amounts due in respect of
such Guarantor Subsidiary's guaranty of the New Notes (or any outstanding Old
Notes).
 
     The Indenture permits the Company and the Guarantor Subsidiaries to incur
certain Secured Indebtedness, including indebtedness under the Senior Bank
Facilities, which will be secured by pledges of all the capital stock of the
Company and the Guarantor Subsidiaries, and security interests in, or liens on,
substantially all other assets of the Company and the Guarantor Subsidiaries.
The New Notes (and the Old Notes) and the Subsidiary Guaranties are unsecured
and therefore do not have the benefit of such collateral. Accordingly, if an
event of default occurs under the Senior Bank Facilities, the lenders will have
a prior right to the assets of the Company and the Guarantor Subsidiaries, and
may foreclose upon such collateral to the exclusion of the holders of the New
Notes (and of any of the Old Notes), notwithstanding the existence of an event
of default with respect thereto. In such event, such assets would first be used
to repay in full amounts outstanding under the Senior Bank Facilities, resulting
in all or a portion of the Company's and the Guarantor Subsidiaries' assets
being unavailable to satisfy the claims of the holders of the New Notes (and of
any of the Old Notes) and other unsecured indebtedness.
 
RESTRICTIVE LOAN COVENANTS
 
     The Senior Bank Facilities will include certain covenants that, among other
things, will restrict the ability of the Company and its subsidiaries to: (i)
dispose of assets; (ii) incur additional indebtedness; (iii) incur guarantee
obligations; (iv) prepay other indebtedness or amend other debt instruments; (v)
pay dividends; (vi) create liens on assets; (vii) enter into sale and leaseback
transactions; (viii) make investments, loans or advances; (ix) make
acquisitions; (x) engage in mergers or consolidations; (xi) change the business
conducted by the Company; (xii) make capital expenditures; or (xiii) engage in
certain transactions with affiliates and otherwise restrict certain corporate
activities. In addition, under the Senior Bank Facilities the Company will be
required to comply with specified financial ratios and tests, including minimum
interest coverage ratios, maximum leverage ratios and minimum net worth tests.
There can be no assurance that these requirements will be met in the future. If
they are not, the holders of the indebtedness under the Senior Bank Facilities
would be entitled to declare such indebtedness immediately due and payable. See
"Description of Senior Bank Facilities."

HOLDING COMPANY STRUCTURE; POSSIBLE UNENFORCEABILITY OF THE SUBSIDIARY
GUARANTIES
 
     The Company is a holding company which derives substantially all of its
operating income from its subsidiaries. The holders of the New Notes (and of any
of the Old Notes) will have no direct claim against the Guarantor Subsidiaries
other than the claim created by the Subsidiary Guaranties, which may themselves
be subject to legal challenge in the event of the bankruptcy of a Guarantor
Subsidiary. See "-- Fraudulent Conveyance." If such a challenge were upheld, the
Subsidiary Guaranties would be unenforceable. To the extent that the Subsidiary
Guaranties are not enforceable, the rights of holders of the New Notes (and of
any of the Old Notes) to participate in any distribution of assets of any
Guarantor Subsidiary upon liquidation, bankruptcy, reorganization or otherwise
may, as is the case with other unsecured creditors of the Company, be subject to
prior claims of creditors of that Guarantor Subsidiary. The Company must rely
upon dividends and other payments from its subsidiaries to generate the funds
necessary to meet its obligations, including the payment of principal of and
interest on the New Notes (and any of the Old Notes). The Indenture contains
covenants that restrict the ability of the Company's Restricted Subsidiaries (as
defined) to enter into agreements limiting distributions and transfers,
including dividends. However, the ability of the Company's subsidiaries to pay
dividends and make other payments may be restricted by, among other things,
applicable state corporate laws and regulations or by terms of agreements to
which they may become party. See "Description of Notes."
 
DEPENDENCE ON KEY PERSONNEL
 
     Three of the Company's senior executives, including the chief executive
officer, did not remain with the Company after the Closing. The Company retained
James K. Hildebrand to serve as Chairman and Chief Executive Officer following
the Merger, and the Company's current management assumed primary responsibility
for the other duties conducted by the departing senior executives. The ability
of the Company to maintain its competitive position will depend to a significant
degree upon its ability to continue to attract and retain highly qualified
managerial and manufacturing personnel. There can be no assurance that the
Company will be able to continue to recruit and retain such personnel. In
particular, the Company is dependent on certain key management personnel, and
there can be no assurance that the loss of key personnel would not have a
material adverse effect on the Company's results of operations. See
"Management."
 
CHANGE OF CONTROL
 
     Upon the occurrence of a Change of Control, unless the Company redeems the
Notes, each holder of the New Notes (and of any outstanding Old Notes) will have
the right to require the Company to repurchase all or any portion of such
holder's Notes at a price equal to 101% of the principal amount thereof, plus
accrued and unpaid interest, if any, to the date of purchase. The occurrence of
a Change of Control would constitute a default under the Senior Bank Facilities.
In addition, the Senior Bank Facilities will prohibit the purchase of the New
Notes (and of any outstanding Old Notes) by the Company in the event of a Change
of Control, unless and until such time as all indebtedness under the Senior Bank
Facilities is repaid in full. The Company's failure to purchase the New Notes
(and any outstanding Old Notes) would result in a default under the Indenture.
The inability to repay the indebtedness under the Senior Bank Facilities, if
accelerated, would also constitute an event of default under the Indenture. In
the event of a Change of Control, there can be no assurance that the Company
would have sufficient assets to satisfy all of its obligations under the Senior
Bank Facilities and the New Notes (and any outstanding Old Notes). See
"Description of Senior Bank Facilities" and "Description of Notes -- Change of
Control."
 
CONCENTRATION OF CUSTOMERS
 
     In 1997, sales to one of the Company's customers, Rockwell International,
accounted for 16.1% of the Company's total net sales, and the Company's top
three customers accounted for approximately 34.8% of the Company's net sales. A
significant reduction of purchases by one or more of the
 
                                       16
   20
 
Company's key industrial customers could have a material adverse effect on the
Company's business, financial condition or results of operations. See
"Business -- Products, Customers and Markets."
 
DEPENDENCE ON INDUSTRY/CYCLICALITY
 
     The Company has historically experienced moderate cyclicality in the heavy
municipal market. Sales of municipal castings are influenced by, among other
things, public spending. The Company's industrial sales are largely dependent on
orders from OEMs of medium- and heavy-duty trucks and truck components and their
first-tier suppliers and orders for farm equipment. The truck market has
historically been subject to fluctuations due to general economic conditions
and, in particular, the industrial sector of the economy. From 1993 to 1995, the
truck market experienced significant growth, while in 1996 the medium- and
heavy-duty truck market declined substantially from 1995 levels. In 1997, the
medium- and heavy-duty truck market increased over 1996 levels but remained
below 1995 levels. There can be no assurance that the truck market will not
decline. The farm equipment market has also experienced cyclicality. A downturn
in these markets could reduce demand for, and prices of, the Company's products.
A significant downturn in either of these markets could have a material adverse
effect on the Company's business, financial condition or results of operations.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
COMPETITION
 
     The markets for the Company's products are highly competitive. Competition
is based not only on price, but also on quality of product, range of capability,
level of service and reliability of delivery. The Company competes with numerous
independent and captive domestic iron foundries, as well as with a number of
foreign iron foundries, including certain foundries located in India. The
Company also competes with several large domestic foundries and manufacturers
whose casting products are made with materials other than ductile and gray iron,
such as steel or aluminum. Industry consolidation over the past decade has
resulted in a significant reduction in the number of smaller foundries and a
rise in the share of production by larger foundries, some of which have
significantly greater financial resources than the Company. There can be no
assurance that the Company will be able to maintain or improve its competitive
position in the markets in which it competes. See "Business -- Competition."
 
FLUCTUATIONS IN PRICE AND SUPPLY OF RAW MATERIALS
 
     The Company is dependent upon outside suppliers for all of its raw material
needs and, therefore, is subject to price increases and delays in receiving
supplies of such materials. Changes in the supply of or demand for raw materials
could affect delivery times and prices. Although historically the Company has
been able to increase prices in response to increased raw material costs, no
assurance can be given that the Company will continue to have available
necessary raw materials at reasonable prices or that any increases in raw
material costs would not have a material adverse effect on the Company's
business, financial condition, or results of operations. See "Business -- Raw
Materials."
 
CONTROLLING SHAREHOLDERS
 
     The Investor Group beneficially owns approximately 90% of the Common Stock
of the Company and, together with the Management Investors, collectively, has
the ability to elect the entire Board of Directors and generally to control the
affairs and policies of the Company. Circumstances may occur
 
                                       17
   21
 
in which the interests of the Investor Group, as shareholders of the Company,
could be in conflict with the interests of the holders of the New Notes (and of
any outstanding Old Notes). In addition, the Investor Group may have an interest
in pursuing acquisitions, divestitures or other transactions that, in their
judgment, could enhance their equity investment, even though such transactions
might involve disproportionate risks to the holders of the New Notes (and of any
outstanding Old Notes). See "Ownership of Securities" and "Certain Relationships
and Related Transactions" and "Business -- Business Strategy."
 
ENVIRONMENTAL MATTERS
 
     The Company's facilities are subject to numerous federal, state and local
laws and regulations relating to the protection of the environment and worker
health and safety, including those relating to discharges to air, water and
land, the handling and disposal of solid and hazardous waste and the cleanup of
properties affected by hazardous substances. The Company does not currently
anticipate any material adverse effect on its operations or financial condition
as a result of its efforts to comply with, or its liabilities under, such
requirements. Risk of environmental liability is inherent in the manufacturing
of casting products, however, and there can be no assurance that material
environmental costs will not arise in the future. In particular, the Company
might incur capital and other costs to comply with increasingly stringent air
emission control laws and enforcement policies. See "Business -- Environmental
Matters."
 
FRAUDULENT CONVEYANCE
 
     The incurrence by the Company of indebtedness such as the Old Notes (and
the New Notes exchanged therefor) to finance the Transactions may be subject to
review under relevant state and federal fraudulent conveyance and similar laws
if a bankruptcy or reorganization case or a lawsuit is commenced by or on behalf
of creditors of the Company. Under these laws, if a court were to find that,
after giving effect to the sale of the Old Notes and the exchange of the New
Notes therefor and the application of the net proceeds therefrom, either (a) the
Company incurred such indebtedness with the intent of hindering, delaying or
defrauding then-existing or future creditors or (b) the Company received less
than a reasonably equivalent value or fair consideration for incurring such
indebtedness and at the time of the incurrence of such indebtedness the Company
(i) was insolvent or was rendered insolvent by reason of such transactions; (ii)
was engaged in a business or transaction for which the assets remaining with the
Company constituted unreasonably small capital; or (iii) intended to incur, or
believed that it would incur, debts beyond its ability to pay as they matured,
such court may subordinate such indebtedness to presently existing and future
indebtedness of the Company, avoid the issuance of such indebtedness and direct
the repayment of any amounts paid thereunder to the creditors of the Company or
take other action detrimental to the holders of such indebtedness.
 
     The measure of insolvency for purposes of determining whether a transfer is
avoidable as a fraudulent transfer varies depending upon the law of the
jurisdiction which is being applied. Generally, however, a debtor would be
considered insolvent if the sum of all its liabilities, including contingent
liabilities, was greater than the value of all its assets at a fair valuation,
or if the present fair saleable value of the debtor's assets was less than the
amount required to repay its probable liabilities on its debts, including
contingent liabilities, as they become absolute and matured.
 
     There can be no assurance as to what standard a court would apply in order
to determine solvency. To the extent that proceeds from the sale of the Old
Notes were used to finance the Transactions, a court may find that the Company
did not receive fair consideration or reasonably equivalent value for the
incurrence of the indebtedness represented thereby. In addition, if a court were
to find that any of the components of the Transactions constituted a fraudulent
transfer, to the extent that proceeds from the sale of the Old Notes were used
to finance such Transactions, a court may find that the Company did not receive
fair consideration or reasonably equivalent value for the incurrence of the
indebtedness represented by the Old Notes.
 
                                       18
   22
 
     The Company believes that it received equivalent value at the time the
indebtedness under the Old Notes was incurred. In addition, the Company does
not, after giving effect to the consummation of the Transactions: (i) believe
that it was insolvent or rendered insolvent; (ii) believe that it was engaged in
a business or transaction for which its remaining assets constitute unreasonably
small capital; or (iii) intended to incur, or believe that it incurred, debts
beyond its ability to pay as they mature. These beliefs are based on the
Company's analysis of internal cash flow projections and estimated values of
assets and liabilities of the Company and the Guarantor Subsidiaries at the time
of the offering of the Old Notes. There can be no assurance, however, that a
court passing on the issues would make the same determination.
 
     In addition, the Subsidiary Guaranties may be subject to review under
relevant federal and state fraudulent conveyance and similar statutes in a
bankruptcy or reorganization case or a lawsuit by or on behalf of creditors of
any of the Guarantor Subsidiaries. In such a case, the analysis set forth above
would generally apply, except that the Subsidiary Guaranties could also be
subject to the claim that, since the Subsidiary Guaranties were incurred for the
benefit of the Company (and only indirectly for the benefit of the Guarantor
Subsidiaries), the obligations of the Guarantor Subsidiaries thereunder were
incurred for less than reasonably equivalent value or fair consideration. A
court could void a Guarantor Subsidiary's obligation under the Subsidiary
Guaranties, subordinate the Subsidiary Guaranties to other indebtedness of a
Guarantor Subsidiary or take other action detrimental to the holders of the Old
Notes (and the New Notes exchanged therefor).
 
ABSENCE OF PUBLIC MARKET; RESTRICTIONS ON TRANSFER
 
     The New Notes are new securities for which there currently is no market.
Although the Initial Purchasers have informed the Company that they currently
intend to make a market in the New Notes, they are not obligated to do so and
any such market making may be discontinued at any time without notice in the
sole discretion of the Initial Purchasers. Accordingly, there can be no
assurance as to the development or liquidity of any market for the New Notes.
The Old Notes are eligible for trading by qualified buyers in the PORTAL market.
The Company does not intend to apply for listing of the Notes or, if issued, the
Exchange Notes, on any securities exchange or for quotation through the National
Association of Securities Dealers Automated Quotation System.
 
     The liquidity of, and trading market for, the New Notes also may be
adversely affected by general declines in the market for similar securities.
Such declines may adversely affect such liquidity and trading markets
independently of the financial performance of, and prospects for, the Company.
 
FORWARD-LOOKING STATEMENTS
 
     This Prospectus contains certain forward-looking statements concerning the
Company's operations, economic performance and financial condition, including,
in particular, the likelihood of the Company's success in developing and
expanding its business. These statements are based upon a number of assumptions
and estimates which are inherently subject to significant uncertainties and
contingencies, many of which are beyond the control of the Company, and reflect
future business decisions which are subject to change. The foregoing description
of risk factors specifies the principal contingencies and uncertainties to which
the Company believes it is subject. Some of these assumptions inevitably will
not materialize, and unanticipated events will occur which will affect the
Company's results.
 
                                USE OF PROCEEDS
 
     There will be no proceeds to the Company from the exchange of Notes
pursuant to the Exchange Offer.

- ---------------
(1) Pro Forma cash and cash equivalents include actual cash and cash equivalents
    at March 31, 1997, plus $2.9 million in repayments of notes receivable from
    certain stockholders of the Company prior to the Merger, less $25.3 million
    to be paid as part of the Merger Price.
 
(2) Based on the Company's results of operations since March 31, 1997, the
    Company estimates the closing net worth adjustment will be approximately
    $12.6 million resulting in a total Merger Price of approximately $261.8
    million, cash on hand of approximately $11.5 million, substantially all of
    which will be applied to fund the Merger Price, and approximately $1.0
    million will be drawn under the Revolving Credit Facility in order to
    provide the remainder of the necessary financing.
 
(3) Total borrowings of up to $30.0 million under the Revolving Credit Facility
    are available, subject to borrowing base limitations, for working capital
    and general corporate purposes, including up to $15.0 million for letters of
    credit. At March 31, 1997, on a pro forma basis after giving effect to the
    Offering, the other Transactions, and the application of the proceeds
    therefrom, as well as borrowing base limitations and $0.6 million of
    outstanding letters of credit, the Company estimates that it would have had
    the ability to borrow approximately $24.8 million under the Revolving Credit
    Facility. See "Description of Senior Bank Facilities."

            NOTES TO SELECTED CONSOLIDATED FINANCIAL AND OTHER DATA
 
(1) Net sales for the years ended March 31, 1993 and 1994 include sales of
    products manufactured in Plant 1, which was closed in 1994 as part of the
    Company's strategy to increase its focus on higher volume, complex parts for
    its industrial customers. The majority of the parts produced in Plant 1 were
    then discontinued. Plant 1 provided sales of $30.9 million and $4.4 million
    for the fiscal years ended March 31, 1993 and 1994, respectively.
 
(2) EBITDA represents operating income plus depreciation and amortization. The
    Company has included information concerning EBITDA because management
    believes that EBITDA is generally accepted as providing useful information
    regarding a company's ability to service and/or incur debt. EBITDA should
    not be considered in isolation or as a substitute for net income, cash flows
    or other income or cash flow data prepared in accordance with generally
    accepted accounting principles or as a measure of a company's profitability
    or liquidity.
 
(3) Cash interest expense is defined as interest expense less amortization of
    debt issuance costs.
 
(4) For purposes of the computation, the ratio of earnings to fixed charges has
    been calculated by dividing (i) income before income taxes and cumulative
    effect of accounting changes plus fixed charges by (ii) fixed charges. Fixed
    charges are equal to interest expense plus the portion of the rent expense
    estimated to represent interest.
 
(5) Employee hours per ton represents the number of hours worked by hourly
    employees during this period (excluding supervisory employee hours) divided
    by the number of tons produced.
 
(6) The scrap rate is the percentage of castings that are determined to be
    unusable prior to delivery to customers.
 
(7) Working capital represents total current assets (excluding cash and cash
    equivalents) less total current liabilities (excluding the revolving credit
    facility and the current portion of long-term debt).

             UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL INFORMATION
 
     The following unaudited pro forma consolidated financial information (the
"Unaudited Pro Forma Financial Information") has been derived by the application
of pro forma adjustments, which give effect to the Transactions, to the
Company's historical consolidated financial statements included elsewhere in
this Prospectus. The unaudited pro forma consolidated balance sheet gives effect
to the Transactions as if such Transactions had occurred on March 31, 1997. The
unaudited pro forma consolidated statement of income for the year ended March
31, 1997 gives effect to the Transactions as if such Transactions were
consummated on April 1, 1996.
 
     The Unaudited Pro Forma Financial Information is for comparative purposes
only and does not purport to represent what the Company's financial position or
results of operations would actually have been had the Transactions in fact
occurred on the assumed dates or to project the Company's financial position or
results of operations for any future date or future period. The Unaudited Pro
Forma Financial Information should be read in conjunction with the Company's
historical consolidated financial statements and related notes included
elsewhere in this Prospectus.
 
     The pro forma adjustments, as described in the accompanying Notes to the
Unaudited Pro Forma Consolidated Balance Sheet and Statement of Income, are
based on available information and certain assumptions that management believes
are reasonable.
 
     The acquisition of the Company is accounted for under the purchase method
of accounting. Assuming the Merger was consummated on March 31, 1997, the Merger
Price would have been $258.3 million, which would include (i) a net worth
adjustment of $9.1 million at the Closing based on a March 31, 1997 closing, and
(ii) an $11.3 million payment to certain former stockholders of the Company upon
consummation of the Merger. The Merger Price reflects the use of approximately
$25.3 million of cash on the Company's balance sheet and borrowings under the
Revolving Credit Facility of $0.9 million. In addition, there will be a
repayment of $2.9 million in notes receivable from certain stockholders of the
Company prior to the Merger, which reduces the net effect on cash to $22.4
million. The Merger Price has been allocated to the tangible and identifiable
intangible assets and to the liabilities based on preliminary estimates of their
fair values. The allocation of the Merger Price is subject to revision when
additional information concerning certain asset valuations is obtained. The
Merger Price is subject to a closing date net worth adjustment.

         to fair value.
 
     (4) The fair value of property, plant and equipment was based on outside

         has been allocated to the fixed asset categories as shown below. The
         remaining economic useful lives used in depreciating the new basis of

     (5) The fair value of identifiable intangible assets was based on an
         outside valuation. The estimated useful lives of the identifiable
         intangible assets are 10 to 40 years.
 
     (6) Deferred income taxes were calculated at 40% of all fair value
         adjustments except for goodwill since there is no step-up in basis of
         assets or liabilities for income tax purposes resulting from the
         Transactions.
 
     (7) An amortization period of 40 years will be used for goodwill because
         the period expected to be benefited exceeds 40 years.

     being amortized using the interest method over the term of the related

                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion and analysis of financial condition and results of
operations covers periods before consummation of the Transactions. The following
information should be read in conjunction with "Selected Consolidated Financial
and Other Data," "Unaudited Pro Forma Consolidated Financial Information," and
the consolidated financial statements and the notes thereto included elsewhere
in this Prospectus.
 
GENERAL
 
     Historically, the Company's net sales have been derived primarily from
sales of heavy municipal and industrial iron castings, which represented 43% and
53%, respectively, of the Company's net sales for the year ended March 31, 1997.
In addition, the Company sells sand control systems and other related products,
which represented 4% of net sales for the year ended March 31, 1997. Sales to
the heavy municipal market have produced, and continue to produce, significantly
higher gross profit margins than sales to the industrial market.
 
     Since 1985, the Company has invested approximately $100 million in its
facilities, with approximately $73 million invested in a major plant
modernization program from 1985 to 1990. This plant modernization program was a
critical part of a long-term strategy to produce higher value-added castings for
its existing industrial customers and to penetrate other selected segments of
that market, while preserving its position as the leader in the heavy municipal
market. This modernization program entailed the closing of the Company's oldest
foundry, Plant 1, and the updating of the Company's other two foundries, Plants
2 and 3. Plant 1 was closed due to its age and the significant investment
required to keep it competitive with more modern mold technology. Plants 2 and 3
were updated with four new molding lines to enable the Company both to produce
higher volume, complex castings for selected industrial segments, and to improve
the Company's cost position in the heavy municipal market. Following the
completion of the modernization program, the Company has steadily decreased its
production of lower margin products such as axle covers and brake drums and
increased the production of more complex, higher value-added parts such as
transmission housings and axle housings. In 1996, the Company began to introduce
what it calls "lightweighted" castings to the municipal market. These
lightweighted castings have been reengineered in order to reduce both their
weight and the amount of raw materials necessary for their manufacture, while
maintaining the high quality performance characteristics of the heavier version
of the casting. This improvement in the design and manufacture of municipal
castings has resulted in lower material costs and improved margins for this
product line. The impact of lightweighted parts on operating results has
generally been lower tons produced, equal or higher unit volumes, higher prices
per ton, lower raw material costs and improved margins.
 
     From 1992 to 1997, the Company's net sales increased from $116.5 million to
$165.4 million, representing a compound annual growth rate of 7.3%, and
operating income increased from $6.2 million to $31.1 million, representing a
compound annual growth rate of 38.1%. The Company's net sales during this period
have been driven primarily by the Company's increased market penetration in
selected products in the medium- and heavy-duty and farm equipment markets, by
increased market demand in the medium- and heavy-duty truck market and, to a
lesser extent, increased heavy municipal market sales. The Company's increase in
operating income during this period was largely the result of improvements in
industrial products and, to a lesser extent, municipal products. Operating
income attributable to industrial castings increased primarily due to higher
production volume, an improved product mix, improved pricing and increased
efficiency in operating its manufacturing equipment, while operating income
attributable to municipal castings increased primarily due to improved pricing
and the effects of the lightweighted casting program. In addition, the Company's
operating income increased due to increased operating leverage.

  COMPARISON OF FISCAL YEAR ENDED MARCH 31, 1997 TO FISCAL YEAR ENDED MARCH 31,
1996
 
     Net Sales.  Net sales were $165.4 million for the year ended March 31,
1997, a decrease of $1.6 million, or 0.9%, from $167.0 million for the year
ended March 31, 1996. Net sales of industrial castings decreased $3.9 million,
or 4.2%, to $88.3 million. The decrease in industrial casting sales was
primarily the result of a decision by the Company to discontinue its production
of certain lower margin brake components, which resulted in a 9,600 ton decrease
in tons produced compared to the year earlier period, and, to a lesser extent,
reduced demand for casting products in the medium- and heavy-duty truck market.
Net sales of municipal castings increased $1.9 million, or 2.7%, to $71.3
million, primarily due to increased pricing. Hartley Controls net sales grew
$0.4 million, or 7.4%, to $5.8 million, principally due to increased volume of
equipment sales.
 
     Gross Profit.  Gross profit was $48.7 million for the year ended March 31,
1997, an increase of $3.4 million, or 7.5%, from $45.3 million for the year
ended March 31, 1996. Gross profit as a percentage of net sales increased to
29.4% for the year ended March 31, 1997, from 27.1% for the year ended March 31,
1996. The increase in gross profit as a percentage of net sales was due mainly
to improved product mix in the industrial product line and greater overall plant
efficiency. Gross profit percentage also improved due to the continued effect of
the lightweighted municipal casting program.
 
     Selling, General and Administrative Expenses.  Selling, general and
administrative expenses were $17.5 million for the year ended March 31, 1997, an
increase of $0.5 million, or 2.9%, from $17.0 million for the year ended March
31, 1996. As a percentage of net sales, selling, general and administrative
expenses increased to 10.6% for the year ended March 31, 1997, from 10.1% for
the year ended March 31, 1996. Approximately $0.2 million of the increase in
selling, general and administrative expenses was due to a non-recurring
charitable contribution and approximately $0.9 million of the increase was due
to increased compensation and benefits to officers of the Company who resigned
at Closing. Excluding the effects of estimated nonrecurring officer compensation
and benefits and the charitable contribution, selling, general and
administrative expenses, as a percentage of net sales, decreased slightly to
8.3% for the year ended March 31, 1997, from 8.4% for the year ended March 31,
1996.
 
     Operating Income.  Operating income increased to $31.1 million for the year
ended March 31, 1997, an increase of $2.8 million or 9.9% from $28.3 million for
the year ended March 31, 1996. As a percentage of net sales, operating income
increased to 18.8% for the year ended March 31, 1997, from 17.0% for the year
ended March 31, 1996. The improvement in operating income was achieved primarily
for the reasons discussed above.

  COMPARISON OF FISCAL YEAR ENDED MARCH 31, 1996 TO FISCAL YEAR ENDED MARCH 31,
1995
 
     Net sales.  Net sales were $167.0 million for the year ended March 31,
1996, an increase of $6.4 million, or 4.0%, from $160.6 million for the year
ended March 31, 1995. Net sales of industrial castings grew $6.6 million, or
7.7%, to $92.2 million. The increase in industrial sales was primarily due to
improved pricing while sales volume remained stable. The improved pricing for
industrial castings was mainly the result of a better industrial product mix as
the Company increased its sales of more complex, value-added industrial
castings. Net sales of municipal castings decreased $1.0 million, or 1.4%, to
$69.4 million, due to a decrease in unit volume, which was partially offset by
improved pricing. The decrease in municipal castings volume was principally due
to artificially high sales in fiscal 1995 resulting from weather conditions.
Fiscal 1995 net sales were affected by poor winter weather in January to March
1994 which resulted in the postponement of certain sales from fiscal 1994 to
fiscal 1995, and mild weather from January to March 1995 which resulted in the
acceleration of sales from fiscal 1996 to fiscal 1995. Total production volume
in tons decreased more significantly than unit volume for municipal sales
because of the effect of the lightweighted casting program. See "-- General."
Hartley Controls net sales grew $0.8 million, or 17.4%, to $5.4 million,
principally due to increased volume of equipment sales.
 
     Gross Profit.  Gross profit was $45.3 million for the year ended March 31,
1996, an increase of $5.7 million, or 14.4%, from $39.6 million for the year
ended March 31, 1995. Gross profit as a percentage of net sales increased to
27.1% for the year ended March 31, 1996, from 24.7% for the year ended March 31,
1995. The continued improvement in gross profit, as a percentage of net sales,
was due to the combined effect of margin improvements in both the industrial and
municipal product lines. Industrial castings gross profit percentage improved
due to the shift to a more profitable product mix and improved efficiency in
plant operations. Municipal castings gross profit percentage improved largely
due to the effect of implementing the lightweighted casting program and an
increase in selling prices.
 
     Selling, General and Administrative Expenses.  Selling, general and
administrative expenses were $17.0 million for the year ended March 31, 1996, an
increase of $0.3 million, or 1.8%, from $16.7 million for the year ended March
31, 1995. As a percentage of net sales, selling, general and administrative
expenses decreased slightly to 10.1% for the year ended March 31, 1996, from
10.4% for the year ended March 31, 1995. Approximately $0.1 million of the
increase in selling, general and administrative expense was due to increased
compensation and benefits to officers of the Company who resigned at Closing.
Excluding the effects of estimated nonrecurring executive compensation and
benefits, selling, general and administrative expenses, as a percentage of net
sales, decreased to 8.4% from 8.6% for the year ended March 31, 1995, primarily
due to the spreading of fixed expenses over a greater volume of sales.
 
     Operating Income.  Operating income increased to $28.3 million for the year
ended March 31, 1996, an increase of $5.3 million, or 23.0%, from $23.0 million
for the year ended March 31, 1995. As a percentage of net sales, operating
income increased to 17.0% for the year ended March 31, 1996, from 14.3% for the
year ended March 31, 1995. The improvement in operating income was achieved
primarily for the reasons discussed above.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     The Company's liquidity needs will arise primarily from debt service on
indebtedness incurred in connection with the Transactions, working capital needs
and the funding of capital expenditures. At March 31, 1997, on a pro forma basis
after giving effect to the Transactions, the Company's consolidated indebtedness
would have been approximately $196.0 million (excluding $0.6 million of
outstanding letters of credit), consisting of $150.0 million of the Notes, $45.0
million in Term Loans, $0.1 million in capital lease obligations and $0.9
million drawn under the Revolving Credit Facility. The degree to which the
Company is leveraged could have a significant effect on its results of
operations.
 
                                       32
   36
 
     Principal and interest payments under the Senior Bank Facilities and the
Notes will represent significant liquidity requirements for the Company. Under
the terms of the Senior Bank Facilities, the Company will be required to make
principal payments totaling approximately $5.0 million in 1998, $5.0 million in
1999, $5.0 million in 2000, $5.0 million in 2001, $5.0 million in 2002, $10.0
million in 2003 and $10.0 million in 2004. Loans under the Senior Bank
Facilities will bear interest at floating rates based upon the interest rate
option selected by the Company. Borrowings under the Revolving Credit Facility
will be subject to a borrowing base. For a description of the Senior Bank
Facilities, see "Description of Senior Bank Facilities."
 
     For the fiscal years ended March 31, 1995, 1996 and 1997, the Company's
capital expenditures were $3.7 million, $7.3 million and $4.5 million,
respectively. The $3.6 million increase in capital expenditures for the fiscal
year ended March 31, 1996 from the comparable period for 1995 was primarily the
result of the expansion of the cooling capabilities of two of the Company's
production lines. Of the $4.5 million of capital expenditures in 1997, an
estimated $4.0 million was attributable to maintenance of capital equipment. The
Company currently plans to make capital expenditures of approximately $6.0
million in the fiscal year ended March 31, 1998, exclusive of any acquisitions.
While a component of the Company's strategy is to make selective acquisitions in
the foundry industry, it currently has no agreements relating to any
acquisitions.
 
     The Company's principal source of cash to fund its liquidity needs will be
net cash from operating activities and borrowings under the Revolving Credit
Facility. Net cash from operating activities for the year ended March 31, 1997
was $23.5 million, an increase of $1.2 million from $22.3 million for the year
ended March 31, 1996, primarily as a result of an increase in net income. Net
cash from operating activities for the year ended March 31, 1996 of $22.3
million represented a decrease of $1.3 million from $23.6 million in the
comparable period of 1995, primarily as a result of a net increase in working
capital (excluding cash and cash equivalents) during 1996 partially offset by
greater net income in 1996.
 
     At March 31, 1997, on a pro forma basis after giving effect to the
Offering, the other Transactions and the application of the proceeds therefrom,
as well as borrowing base limitations and $0.6 million of outstanding letters of
credit, the Company estimates that it would have had the ability to borrow
approximately $24.8 million under the Revolving Credit Facility. Amounts under
the Revolving Credit Facility may be used for working capital and general
corporate purposes, subject to certain limitations under the Senior Bank
Facilities. The Company believes that cash generated from operations, together
with the amounts available under the Revolving Credit Facility, will be adequate
to meet its debt service requirements, anticipated capital expenditures and
working capital needs for the foreseeable future, although no assurance can be
given in this regard. The Company also believes that such resources, together
with the potential future use of debt or equity financing, will allow the
Company to pursue its strategic goal of making selective acquisitions. The
Company's future operating performance and ability to service or refinance the
Notes and to extend or refinance the Senior Bank Facilities will be subject to
future economic conditions and to financial, business and other factors, many of
which are beyond the Company's control.
 
RAW MATERIALS
 
     Although the prices of all raw materials used by the Company vary, the
fluctuations in the price of steel scrap are the most significant to the
Company. The Company has arrangements with most of its industrial customers
which require the Company to adjust industrial casting prices to reflect scrap
price fluctuations. In periods of rapidly rising or falling scrap prices, these
adjustments will lag the current scrap price because they are generally based on
average market prices for prior periods, which periods vary by customer but are
generally no longer than six months. Castings are generally sold to the heavy
municipal market on a bid basis and, after a bid is won, the price for the
municipal casting subject to the bid generally cannot be adjusted for raw
material price increases. However, in most cases the Company has been successful
in obtaining higher municipal casting unit prices in subsequent bids to
compensate for rises in scrap prices in prior periods. Rapidly
 
                                       33
   37
 
fluctuating scrap prices may have a temporary adverse or positive effect on the
Company's results of operations.
 
INFLATION
 
     The Company does not believe that inflation has had a material impact on
its financial position or results of operations during the three years ended
March 31, 1997.
 
CYCLICALITY AND SEASONALITY
 
     The Company has historically experienced moderate cyclicality in the heavy
municipal market. Sales of municipal products are influenced by, among other
things, public spending. In the industrial market, the Company has experienced
cyclicality in sales resulting from fluctuations in the medium-and heavy-duty
truck market and the farm equipment market, which are subject to general
economic trends.
 
     The Company experiences seasonality in its municipal business where sales
tend to be higher during the construction season, which occurs during the warmer
months, generally the first and second quarters of the Company's fiscal year.
Seasonal weather can also impact the Company's net sales from year to year, as
warmer weather conditions in the months of January through March of any given
year can allow shipments during that time which would normally occur in the
subsequent fiscal year. The Company maintains level production throughout the
year in anticipation of such seasonality and does not experience production
volume fluctuations as a result. The Company builds inventory in anticipation of
the construction season with such inventories reaching a peak near the end of
its fiscal year in March. The Company has not historically experienced
seasonality in industrial casting sales.

transfer (a "Book-Entry Confirmation") of such Old Notes, if such procedure is
available, into the Exchange Agent's account at The Depository Trust Company
(the "Book-Entry Transfer Facility") pursuant to the procedure for book-entry
transfer described below, must be received by the Exchange Agent prior to the
Expiration Date, or the holder must comply with the guaranteed delivery
procedures described below. THE METHOD OF DELIVERY OF OLD NOTES, LETTER OF
TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS IS AT THE ELECTION AND RISK OF THE
HOLDER. IF SUCH DELIVERY IS BY MAIL, IT IS RECOMMENDED THAT REGISTERED MAIL,
PROPERLY INSURED, WITH RETURN RECEIPT REQUESTED, BE USED. IN ALL CASES,
SUFFICIENT TIME SHOULD BE
 
                                       35
   39
 
ALLOWED TO ASSURE TIMELY DELIVERY. NO LETTERS OF TRANSMITTAL OR OLD NOTES SHOULD
BE SENT TO THE COMPANY.
 
     Signatures on a Letter of Transmittal or a notice of withdrawal, as the
case may be, must be guaranteed unless the Old Notes surrendered for exchange
pursuant thereto are tendered (i) by registered holder of the Old Notes who has
not completed the box entitled "Special Issuance Instructions" or "Special
Delivery Instructions" on the Letter of Transmittal or (ii) for the account of
an Eligible Institution (as defined below). In the event that signatures on a
Letter of Transmittal or a notice of withdrawal, as the case may be, are
required to be guaranteed, such guarantees must be by a firm that is a member or
participant in the Securities Transfer Agents Medallion Program, the New York
Stock Exchange Medallion Signature Program or the Stock Exchange Medallion
Program or by an "eligible guarantor institution" within the meaning of Rule
17Ad-15 under the Exchange Act (collectively, "Eligible Institutions"). If Old
Notes are registered in the name of a person other than a signer of the Letter
of Transmittal, the Old Notes surrendered for exchange must be endorsed by or be
accompanied by a written instrument or instruments of transfer or exchange, in
satisfactory form as determined by the Company in its sole discretion, duly
executed by, the registered holder with the signature thereon guaranteed by an
Eligible Institution.
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance of Old Notes tendered for exchange will be determined by
the Company in its sole discretion, which determination shall be final and
binding. The Company reserves the absolute right to reject any and all tenders
of any particular Old Notes not properly tendered or to not accept any
particular Old Notes which acceptance might, in the judgment of the Company or
its counsel, be unlawful. The Company also reserves the absolute right to waive
any defects or irregularities or conditions of the Exchange Offer as to any
particular Old Notes either before or after the Expiration Date (including the
right to waive the ineligibility of any holder who seeks to tender Old Notes in
the Exchange Offer). The interpretation of the terms and conditions of the
Exchange Offer as to any particular Old Notes either before or after the
Expiration Date (including the Letter of Transmittal and the instructions
thereto) by the Company shall be final and binding on all parties. Unless
waived, any defects or irregularities in connection with tenders of Old Notes
for exchange must be cured within such reasonable period of time as the Company
shall determine. Neither the Company, the Exchange Agent nor any other person
shall be under any duty to give notification of any defect or irregularity with
respect to any tender of Old Notes for exchange, nor shall any of them incur any
liability for failure to give such notification.
 
     If the Letter of Transmittal or any Old Notes or powers of attorney are
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing, and, unless waived by
the Company, proper evidence satisfactory to the Company of their authority to
do so must be submitted.
 
     By tendering, each broker-dealer holder will represent to the Company that,
among other things, the New Notes acquired pursuant to the Exchange Offer are
being obtained in the ordinary course of business of the holder and any
beneficial holder, that neither the holder nor any such beneficial holder has an
arrangement or understanding with any person to participate in the distribution
of such New Notes and that neither the holder nor any such other person is an
"affiliate," as defined under Rule 405 of the Securities Act, of the Company. If
the holder is not a broker-dealer, the holder must represent that it is not
engaged in nor does it intend to engage in a distribution of the New Notes.
 
ACCEPTANCE OF OLD NOTES FOR EXCHANGE; DELIVERY OF NEW NOTES
 
     For each Old Note accepted for exchange, the holder of such Old Note will

than the registered tendering holder will be responsible for the payment of any
applicable transfer tax thereon.
 
CONSEQUENCES OF FAILURE TO EXCHANGE; RESALES OF NEW NOTES
 
     Holders of Old Notes who do not exchange their Old Notes for New Notes
pursuant to the Exchange Offer will continue to be subject to the restrictions
on transfer of such Old Notes as set forth in the legend thereon as a
consequence of the issuance of the Old Notes pursuant to the exemptions from, or
in transactions not subject to, the registration requirements of, the Securities
Act and applicable state securities law. Old Notes not exchanged pursuant to the
Exchange Offer will continue to accrue interest at 11 1/8% per annum and will
otherwise remain outstanding in accordance with their terms. Holders of Old
Notes do not have any appraisal or dissenters' rights under the Delaware General
Corporation Law in connection with the Exchange Offer. In general, the Old Notes
may not be offered or sold unless registered under the Securities Act, except
pursuant to an exemption from, or in a transaction not subject to, the
Securities Act and applicable state securities laws. The Company does not
currently anticipate that it will register the Old Notes under the Securities
Act. However, (i) if the Initial Purchasers so request with respect to Old Notes
not eligible to be exchanged for New Notes in the Exchange Offer and held by
them following consummation of the Exchange Offer or (ii) if any holder of Old
Notes is not eligible to participate in the Exchange Offer, or, in the case of
any holder of Old Notes that participates in the Exchange
 
                                       39
   43
 
Offer, does not receive freely tradable New Notes in exchange for Old Notes, the
Company is obligated to file a Registration Statement on the appropriate form
under the Securities Act relating to the Old Notes held by such persons.
 
     Based on certain interpretive letters issued by the staff of the Commission
to third parties in unrelated transactions, it is the Company's view that New
Notes issued pursuant to the Exchange Offer may be offered for resale, resold or
otherwise transferred by holders thereof (other than (i) any such holder which
is an "affiliate" of the Company within the meaning of Rule 405 under the
Securities Act or (ii) any broker-dealer that purchases Notes form the Company
to resell pursuant to Rule 144A or any other available exemption) without
compliance with the registration and prospectus delivery provisions of the
Securities Act, provided that such New Notes are acquired in the ordinary course
of such holders' business and such holders have no intention, or any arrangement
or understanding with any person, to participate in the distribution of such New
Notes. If any holder has any arrangement or understanding with respect to the
distribution of the New Notes to be acquired pursuant to the Exchange Offer,
such holder (i) could not rely on the applicable interpretations of the staff of
the Commission and (ii) must comply with the registration and prospectus
delivery requirements of the Securities Act in connection with a secondary
resale transaction. A broker-dealer who holds Old Notes that were acquired for
its own account as a result of market-making or other trading activities may be
deemed to be an "underwriter" within the meaning of the Securities Act and must,
therefore, deliver a prospectus meeting the requirements of the Securities Act
in connection with any resale of New Notes. Each such broker-dealer that
acquired by such broker-dealer as a result of market-making activities or other
trading activities, must acknowledge in the Letter of Transmittal that it will
deliver a prospectus in connection with any resale of such New Notes. See "Plan
of Distribution."
 
     In addition, to comply with the securities laws of certain jurisdictions,
if applicable, the New Notes may not be offered or sold unless they have been
registered or qualified for sale in such jurisdiction or an exemption from
registration or qualification is available and is complied with. The Company has
agreed, pursuant to the Registration Rights Agreement and subject to certain
specified limitations therein, to register or qualify the new Notes for offer or
sale under the securities or blue sky laws of such jurisdictions as any holder
of the Notes reasonably requests in writing.

OVERVIEW
 
     The Company, founded in 1872, is one of the largest manufacturers of a wide
range of high quality ductile and gray iron castings for the heavy municipal
market and selected segments of the industrial market. The Company believes it
is the largest manufacturer of heavy municipal iron castings in the United
States with approximately a 19% market share in calendar year 1996. The
Company's broad range of heavy municipal iron castings includes manhole covers
and frames, storm sewer frames and grates, heavy duty airport castings,
specialized trench drain castings, specialty flood control castings and
ornamental tree grates. These municipal castings are sold throughout the United
States to state and local government entities, utility companies, precast
concrete manhole structure producers and contractors for both new construction
and infrastructure replacement. The municipal market generated approximately 43%
of the Company's 1997 net sales. The Company believes it is also a leading
manufacturer of a wide range of complex industrial castings, including castings
for medium- and heavy-duty truck drive line components, a broad range of
castings for the farm equipment industry and specific components for compressors
used in heating, ventilation and air conditioning systems ("HVAC"). The
industrial market generated approximately 53% of the Company's 1997 net sales.
In addition, the Company engineers, manufactures and sells customized sand
control systems and related products, which are an essential part of the casting
process, to other iron foundries. Sales of these sand control systems and
related products represented approximately 4% of the Company's 1997 net sales.
 
     The Company currently operates two modern foundries with an annual
aggregate rated capacity of approximately 187,000 tons at a single site in
Neenah, Wisconsin. Since 1985, the Company has invested approximately $100
million in its production facilities, with approximately $73 million invested in
a major plant modernization program from 1985 to 1990. This plant modernization
program was a critical part of a long-term strategy to produce higher volume,
value-added castings for its existing industrial customers and to penetrate
other selected segments of the industrial market, while preserving its position
as the leader in the heavy municipal market. This modernization program entailed
the closing of the Company's oldest foundry, Plant 1, and the updating of the
Company's other two foundries, Plants 2 and 3, which enabled the Company both to
produce higher volume, complex castings for selected industrial segments and to
improve the Company's cost position in the heavy municipal market. Following the
completion of the modernization program, the Company has steadily decreased its
production of lower margin products such as axle covers and brake drums and
increased the production of higher margin, more complex parts such as
transmission and axle housings. As a result of this strategy, the Company's
ongoing improvements in its manufacturing process and increased demand for
medium- and heavy-duty truck components, net sales and EBITDA (as defined) have
increased substantially. From 1992 to 1997, net sales have grown from $116.5
million to $165.4 million, representing a compound annual growth rate of 7.3%,
and EBITDA has grown from $13.4 million to $38.0 million during the same period,
representing a compound annual growth rate of 23.2%.
 
INDUSTRY
 
     The United States casting industry includes products made from gray,
malleable and ductile iron, aluminum, steel and various other metals, each with
different underlying structural and performance properties such as strength,
durability and weight. Gray iron, the oldest and most widely used cast iron, is
readily cast into intricate shapes that are easily machined and wear resistant.
Malleable iron, the least used form of iron, is stronger than gray iron and is
more costly than either gray or ductile iron. Ductile iron is also readily cast
into intricate shapes, and due to the addition of alloys during the casting
process, has greater strength and ductility than gray iron. As a result, ductile
iron is used as a higher-strength substitute for gray iron and a lower-cost
substitute
 
                                       41
   45
 
for malleable iron and, in certain applications, steel. The Company manufactures
both gray and ductile iron which it sells into two broad end markets, the
municipal and industrial markets.
 
     The municipal market consists of the heavy municipal market and the water
works market. The heavy municipal market is composed of "standard" castings
(consisting primarily of storm and sanitary sewer castings including manhole
covers and frames and storm sewer frames and grates), and "specialty" castings
(consisting primarily of heavy duty airport castings, trench drain castings,
flood control castings, special manhole and inlet castings and ornamental tree
grates). The water works market consists of certain pipe fittings, valves and
fire hydrants. The Company competes in the heavy municipal market and does not
participate in the water works market. The industrial market includes segments
such as car/light truck, medium- and heavy-duty truck, farm equipment and HVAC.
Of these, the Company primarily provides parts to the medium- and heavy-duty
truck, farm equipment and, to a lesser extent, HVAC segments. Since 1986, the
industrial market has steadily increased its demand for ductile iron due to its
superior performance properties such as strength, ductility and resistance to
stress and mechanical shock. The heavy municipal market utilizes gray iron for
the overwhelming majority of the parts it requires because gray iron continues
to be the most cost-effective material for most municipal applications.
 
     The United States iron foundry industry is highly fragmented despite
significant consolidation over the past decade. In 1986, there were
approximately 880 foundries engaged in the casting of gray, ductile and
malleable irons, with an aggregate capacity of approximately 15 million tons
according to Stratecasts, Inc. a foundry industry research and consulting
organization. By 1996, the number of iron foundries had decreased to
approximately 730, with an aggregate capacity of approximately 13 million tons,
with further consolidation expected to take place. Many smaller foundries have
closed due to the increasing cost of complying with environmental and other
governmental regulations and their inability to satisfy the increasing demand
for higher quality, more complex castings. Due to capacity achieved through
consolidation and technological advancements, the output per remaining foundry
has risen.
 
     In the heavy municipal market, a significant share of the market is served
by a few large foundries, including the Company. Foreign competition,
particularly from India, which had a strong presence in the heavy municipal
market in the past, has receded over the last 18 months as a result of both
antidumping and countervailing duty litigation and increasingly stringent
emission controls in such countries. Such foreign competition, which continues
to be a factor in the heavy municipal market, is primarily present in the
western and eastern coastal states due in part to the costs associated with
transportation. The industrial market has experienced substantial change over
the last 20 years due to two major initiatives by industrial original equipment
manufacturers and their first tier suppliers. The first, outsourcing, has meant
the closing of automotive and other captive foundries as OEMs and their first
tier suppliers focus on core businesses and take advantage of specialized skills
and lower manufacturing and labor costs of independent foundries. Second, OEMs
and their first tier suppliers are reducing the number of suppliers with whom
they work in an effort to eliminate duplicative overhead at multiple suppliers,
take advantage of economies of scale inherent in volume production and confine
suppliers to those with the resources necessary to satisfy stringent quality and
dependability criteria.
 
COMPETITIVE ADVANTAGES
 
     The Company believes it benefits from the following competitive advantages,
which have enabled it to increase sales and operating profitability and to
maintain its position as one of the leaders in the iron casting industry.
 
     Leading Market Position.  The Company believes it is the largest
manufacturer of heavy municipal iron castings in the United States with
approximately a 19% market share in calendar year 1996. Furthermore, the
Company, which has produced municipal castings for over 70 years has, according
to its estimates, over a 50% market share in nine of the top ten states in which
the
 
                                       42
   46
 
Company sells heavy municipal castings. Sales in those states represented
approximately 69% of the Company's municipal sales in 1997. The Company believes
it is also one of the largest manufacturers of iron castings for selected
segments of the industrial market, including the medium-and heavy-duty truck and
farm equipment segments. The Company is the sole sourced supplier for over 85%
of the industrial products it produces and has multi-year arrangements with
certain of its largest customers. The Company believes it can continue to
capitalize on its strong market position to generate additional revenues and
realize economies of scale, thereby increasing margins and earnings.
 
     Low Cost Structure.  As a result of its size, significant investment in
equipment and technology and focus on improving efficiency, the Company believes
it possesses a highly competitive cost structure. Since 1985, the Company has
invested approximately $100 million in its production facilities, with
approximately $73 million invested in plant modernization and new equipment from
1985 to 1990. These investments, combined with the Company's ongoing
improvements to its manufacturing process, have substantially increased
efficiency and manufacturing productivity. From 1992 to 1997, the Company
reduced its scrap rate from 3.5% to 2.0%, which the Company believes is one of
the lowest scrap rates in the industry. During the same period, the Company
reduced its employee hours per ton by approximately 40% from 14.8 to 9.0, while
improving product quality levels and producing higher margin, more complex
parts.
 
     Broad Product Offering.  The Company carries a broad range of products,
offering more than 4,400 patterns that can produce over 20,000 part combinations
for the heavy municipal market, and more than 350 patterns for the industrial
market. The Company believes its municipal catalog offers the largest castings
selection of any foundry serving the heavy municipal market. This extensive
product offering, which includes hundreds of one-of-a-kind specialty items,
enables the Company to compete throughout the United States and provide a
substantial number of the many types of municipal castings required for
individual projects. Heavy municipal castings are manufactured from
Company-owned patterns which have been appraised by independent appraisers to be
in excess of $22 million. Additionally, the Company's extensive and growing
offering of complex industrial castings enables it to more effectively service
its customers' increasing needs for highly engineered cast parts and often
positions the Company as the sole source of supply to original equipment
manufacturers ("OEMs") and their first tier suppliers. The Company's broad
industrial product offering and its recognized casting engineering expertise
have become increasingly important as large industrial customers seek to reduce
the number of suppliers with whom they conduct business.
 
     Strong, Diverse Customer Relationships.  The Company continually focuses on
establishing and maintaining strong relationships with its customers. In the
heavy municipal market, the Company currently sells to over 17,000 active
customers in all 50 states, with the majority of its sales concentrated in the
midwestern states. The Company believes it has the largest sales and marketing
effort of any foundry serving the heavy municipal market, including 47 Company
employees and 26 commissioned representatives. The Company believes the size of
its marketing effort, the breadth of its product offering and the level of its
technical support provide it with a significant competitive advantage and will
allow it to further strengthen its leading position in the heavy municipal
market. With respect to the industrial market, the Company has established
strong relationships with leading manufacturers of medium- and heavy-duty truck
components, farm equipment and HVAC systems. The Company is the sole sourced
provider for over 85% of the products it currently supplies to its industrial
customer base and has multi-year arrangements with certain of its largest
customers. Furthermore, the average industrial casting typically takes between
12 and 18 months to go from the design phase to full production and has an
average life cycle of approximately 8 to 10 years. This lengthy development
process, in which the Company actively participates, provides the Company with
an inventory of products that cannot be quickly replicated by its competitors.
Historically, the foundry that has originally manufactured an industrial part
has continued to manufacture that part throughout its product life cycle. The
Company's participation in both the heavy municipal and
 
                                       43
   47
 
industrial markets helps to diversify the Company's business and to reduce the
Company's reliance on individual customers or end-use markets.
 
     High Quality Products and Customer Service.  The Company believes it enjoys
a reputation for providing a high level of customer service and is recognized
for its ability to consistently manufacture high-quality, complex products. The
Company believes its manufacturing capabilities and process controls allow it to
manufacture high quality castings which are dimensionally and metallurgically
consistent. In addition to providing high quality products, the Company
emphasizes customer service by providing tooling and engineering development
support to its customers, consistent on-time delivery utilizing its own fleet of
trucks for delivery of many of its municipal products and a small portion of the
Company's industrial products and follow-up through its sales and marketing
team. The Company believes its ability to provide such product quality and
responsive service has fostered customer loyalty and long-term relationships.
 
     Experienced Management Team with Significant Equity Stake.  The top seven
members of the Company's senior operating management have an average of
approximately 12 years with the Company and 23 years in the iron foundry
industry. Certain members of the Company's management (the "Management
Investors") beneficially own, on a fully diluted basis, approximately 10% of the
common stock of the Company.
 
BUSINESS STRATEGY
 
     The Company's strategy for achieving continued growth in sales and
profitability includes: (i) increasing the sale of higher margin products, (ii)
selectively entering new markets, (iii) improving operating performance and (iv)
making selective acquisitions.
 
     Increasing the Sale of Higher Margin Products.  The Company continually
strives to improve the margins on the parts it produces. In the heavy municipal
market, the Company has historically maintained strong margins by periodically
implementing price increases and introducing new, higher value-added products.
For example, the Company is currently leading the market in the sale of
lightweighted municipal castings, which are less costly to handle and require
less raw material to produce. The Company believes incremental margin
improvements will be realized from the Company's increased production of these
lightweighted products. In the industrial market, the Company increased its
focus on manufacturing complex, highly engineered castings in the early 1990s
following substantial capital investment in the late 1980s. Since 1991, the
Company has steadily increased the volume, array and complexity of the parts it
produces for its industrial customers. The Company intends to continue to pursue
opportunities to produce more complex, higher value-added castings, thereby
continuing to improve product margins.
 
     Selectively Entering New Markets.  The Company intends to selectively
expand its presence in both the heavy municipal and industrial markets. In the
heavy municipal market, the Company is considering expanding its product
offering in high volume markets such as New York and Nevada where the Company
already has sales representatives in place and for which the Company has already
invested in certain of the toolings necessary to meet potential product demand.
In addition, the Company is exploring further opportunities in New Jersey, New
Hampshire and Massachusetts. The Company's strategy in its chosen industrial
segments is to continue to increase its penetration of existing customers and to
develop similar relationships with other selected industrial companies which
would value the Company's technical ability and high level of product quality
and customer service. The Company also intends to explore opportunities in
austempering (heat-treating ductile iron) and machining and assembling
sub-components for specific industrial customers.
 
     Improving Operating Performance.  The Company operates two modern
foundries, and believes it possesses a highly competitive cost structure. The
Company intends to continue to seek ways to capitalize on and extend its
technological expertise and operating efficiencies, thereby reducing its
operating costs. In contrast to the major investments made from 1985 to 1990,
which significantly improved both manufacturing capacity and efficiency, the
Company's near term capital
 
                                       44
   48
 
expenditures will be focused primarily on incrementally improving efficiency and
reducing costs through projects such as: (i) sand system optimization, (ii)
material handling improvements and (iii) energy utilization improvements.
 
     Making Selective Acquisitions.  The United States iron foundry industry is
highly fragmented despite significant consolidation over the past decade. In
1986, there were approximately 880 foundries engaged in the casting of iron,
with an aggregate capacity of approximately 15 million tons according to
Stratecasts, Inc., a foundry industry research and consulting organization. By
1996, the number of iron foundries decreased to approximately 730, with an
aggregate capacity of approximately 13 million tons. Management believes the
consolidation that has occurred will continue, particularly in the industrial
market, as technical, environmental and quality standards continue to increase.
The Company intends to pursue selective acquisition opportunities that
complement its existing product offering or enable the Company to expand its
presence in selected geographic areas of the heavy municipal market. The Company
believes such acquisitions will provide opportunities for incremental revenue
and cash flow by leveraging the Company's current expertise in manufacturing,

(1) Net sales include sales of Neenah Foundry only.
 
(2) No municipal customer represented more than 1.2% of Neenah Foundry's net
    sales for the fiscal years ended March 31, 1996 or 1997.
 
(3) Commencing in the second quarter of calendar 1996, the Company decided to
    discontinue the production of certain lower margin brake components as part
    of its strategy to increase its focus on higher volume, complex parts for
    its industrial customers. These brake components accounted for 8.3% of
    medium- and heavy-duty truck net sales in fiscal 1996 and 1.0% in fiscal
    1997.
 
     Heavy Municipal.  Based on industry reported data, the Company believes it
is the largest manufacturer of heavy municipal iron castings in the United
States with an estimated 19% market share in calendar year 1996. The Company's
broad heavy municipal product line consists of two general categories of
castings, "standard" and "specialty" castings. Standard castings principally
consist of storm and sanitary sewer castings which are consistent with
pre-existing dimension and strength specifications established by local
authorities. Standard castings are generally high volume items that are
routinely used in new construction and infrastructure replacement. Specialty
castings are generally lower volume, higher margin products which include
heavy-duty airport castings, trench drain castings, flood control castings,
special manhole and inlet castings and ornamental tree grates. These specialty
items are frequently selected and/or specified from the Company's municipal
product catalog and its tree grate catalog, which together encompass over 4,400
standard and specialty patterns. For many of these specialty products, the
Company believes it is the only manufacturer with existing patterns to produce
such a particular casting, although a competing manufacturer could elect to make
the investment in patterns or equipment necessary to produce such a casting.
 
     The Company's municipal castings are sold to state and local government
entities, utility companies, pre-cast concrete manhole structure producers and
contractors for both new construction and infrastructure replacement. The
Company's 17,000 active municipal customers generally make purchase decisions
based on a number of criteria including acceptability of the product per local
specification, quality, service, price and the customer's relationship with the
foundry. Relative to customers in the industrial market, municipal market
customers are less technically demanding and rely on published product
specifications to ensure product performance.
 
     A key aspect of winning orders in the heavy municipal market is the
specification process in which a local authority or design engineer sets
specific criteria for the casting or castings to be used in a particular
project. Those criteria then become part of the formal plans and specifications
that will govern the acceptability of castings for a particular project. The
Company seeks to be an active participant in the specification process. Its
sales staff makes frequent calls on design engineers as part of a continuous
effort to stay abreast of current specifications and upcoming projects. In these
sales calls, the Company seeks to create opportunities for the selection of
specifications which utilize an existing Company pattern. Although in many cases
the design engineer who sets the specification does not make the purchase
decision, when the Company's specialty product is specified it becomes more
difficult for another manufacturer to provide an alternate part which is
considered acceptable. The Company's professional sales staff and product
engineering department are highly regarded by design engineers and are
frequently consulted during the specification drafting process. The Company
believes its reputation for its product engineering support, consistent quality
and reliable service have made the Company's municipal and tree grate catalogs
two of the most frequently used specification design tools in the municipal
casting industry.
 
     Over the past two years, the Company has begun to introduce what it calls
"lightweighted" parts to the heavy municipal market. These lightweighted parts
have been reengineered in order to reduce both their weight and the amount of
raw materials necessary for their manufacture, while maintaining the high
quality performance characteristics of the heavier version of the casting. This
improvement in the design and manufacture of municipal castings has resulted in
lower material costs and improved margins for this product line. The Company is
able to manufacture lightweighted castings because its manufacturing processes
enable it to refine castings walls down to very narrow
 
                                       46
   50
 
tolerances, many of which are currently not achievable by the Company's
competitors. While only a portion of the municipal castings the Company sells
are candidates for lightweighting, the Company expects to continue to increase
the number of lightweighted castings which it offers for sale over the next
several years.
 
     Industrial.  The Company believes it is a leading manufacturer of a wide
range of complex industrial castings, including castings for medium- and
heavy-duty truck drive line components and farm equipment as well as castings
for specific components for compressors used in HVAC systems. The Company's
industrial castings have increased in complexity since the early 1990's and are
generally produced in higher volumes than municipal castings. Complexity in the
industrial market is determined by the intricacy of a casting's shape, the
thinness of its walls and the amount of processing by a customer required before
a part is suitable for use by it. OEMs and their first tier suppliers have been
demanding higher complexity parts principally to reduce labor costs in their own
production processes by using fewer parts to manufacture the same finished
product or assembly and by using parts which require less preparation before
entering the production process.
 
     The Company's industrial castings are primarily sold to a limited number of
customers with whom the Company has established a close working relationship.
The Company has sold to certain industrial customers for over 20 years and
currently has multi-year arrangements with certain of those customers. These
customers make purchasing decisions based on, among other things, technical
ability, price, service, quality assurance systems, facility capabilities and
reputation. However, as in the municipal market, the Company's assistance in
product engineering plays an important role in winning the award of industrial
castings. The average industrial casting typically takes between 12 and 18
months to go from the design phase to full production and has an average product
life cycle of approximately 8 to 10 years. The patterns for industrial castings,
unlike the patterns for municipal castings, are owned by the Company's customers
rather than the Company, however, such industrial patterns are not readily
transferrable to other foundries without, in most cases, significant additional
investment. Although foundries, including the Company, do not design industrial
castings, a close working relationship between a foundry and the customer during
a product launch is critical to reduce potential production problems and
minimize the customer's risk of incurring lost sales or reputation damage due to
a delayed launch. Involvement by a foundry early in the design process generally
improves the likelihood that the customer will design a casting within the
manufacturing capabilities of such foundry and also improves the likelihood that
such foundry will be awarded the casting for full production.
 
     The Company is the sole sourced supplier of over 85% of the industrial
castings it currently produces. Historically, the Company has retained
approximately 90% of the castings it has been awarded throughout the product
life cycle, which is typical for the industry. The Company believes industrial
customers will continue to seek out foundries with a strong reputation for
performance who are capable of providing a cost-effective combination of
manufacturing technology and quality. The Company's strategy is to further its
relationships with existing customers by participating in the design and
production of more complex industrial castings, while seeking out selected new
customers who would value the Company's performance reputation, technical
ability and high level of quality and service.
 
     In addition to increasing its sales to existing customers and seeking out
new customers, the Company intends to explore opportunities in austempering and
machining and assembling sub-components for specific industrial customers.
Austempering is the process of heat treating a ductile iron casting to increase
its strength, thereby increasing the casting's ability to replace steel in
additional applications. Machining and sub-assembling are value-added processes
often performed by the OEM or third parties. Austempering, machining and
sub-assembly are both processes which generally provide higher margins and
increase a customer's reliance on the manufacturer.

SALES AND MARKETING
 
     Heavy Municipal.  Over its 70 years of heavy municipal market
participation, the Company has emphasized sales and marketing and believes it
has built a strong reputation for customer service. The Company believes it is
one of the leaders in United States heavy municipal casting production and has
strong name recognition. The Company has the largest sales and marketing effort
of any foundry serving the heavy municipal market, including 47 Company
employees and 26 commissioned representatives. The dedicated sales force works
out of regional sales offices to market the Company's municipal castings to
contractors and state and local governmental entities throughout the United
States. The Company operates nine regional distribution and sales centers and
has two other sales offices in Oklahoma City, Oklahoma and Norwood,
Pennsylvania. The Company believes this regional approach enhances its knowledge
of local specifications and its position in the heavy municipal market.
 
     Industrial.  The Company employs a dedicated industrial casting sales force
of six people, five based in Neenah, Wisconsin and one based in Mansfield, Ohio.
These six people consist of three account coordinators, who support the ongoing
customer relationships and organize the scheduling and delivery of shipments,
and three major account managers who work with customers' engineers and
procurement representatives, Company engineers, manufacturing management and
quality assurance representatives throughout all stages of the production
process to ensure that the final product consistently meets or exceeds customer
specifications. This team approach between sales, manufacturing, marketing,
engineering and quality assurance is an integral part of the Company's marketing
strategy.
 
MANUFACTURING PROCESS
 
     The Company operates two modern foundries with an annual rated capacity of
approximately 187,000 tons at a single location in Neenah, Wisconsin. The
Company's foundries manufacture gray and ductile iron and cast it into intricate
shapes according to customer metallurgical and dimensional specifications. Since
1985, the Company has invested approximately $100 million in its production
facilities, with approximately $73 million invested from 1985 to 1990 in plant
modernization and new equipment. The Company also continually invests in the
improvement of process controls and product performance and believes that these
investments and its significant experience in the industry have made it one of
the most efficient manufacturers of industrial and heavy municipal casting
products. During 1997, the Company had a combined scrap rate of 2.0%, which it
believes was one of the lowest in the industry.
 
     The casting process involves using metal, wood or urethane patterns to make
an impression of a casting product in a mold made primarily of sand. Cores, also
made primarily of sand, are used to make the internal cavities and openings in a
casting product. Once the casting impression is made in the mold, the cores are
set into the mold and the mold is closed. Molten metal is then poured into the
mold, fills the mold cavity and takes on the shape of the desired casting
product. Once the iron has solidified and cooled, the mold is shaken from the
casting and the sand is recycled. The selection of the appropriate casting
method, pattern, core making equipment and sand and other raw materials depends
on the final product and its complexity, specifications, and function as well as
intended production volumes. Because the casting process involves many critical
variables, such as choice of raw materials, design and production of tooling,
iron chemistry and metallurgy, and core and molding sand properties, it is
important to monitor the process parameters closely to ensure dimensional
precision and metallurgical consistency. See "-- Quality Assurance."
 
     The Company continually seeks to find ways to expand the capabilities of
existing technology to improve manufacturing processes. An example of this
expansion is the Company's integration of Disamatic molding machines into its
operations. Disamatic molding machines are considered to be among the most
efficient sand molding machines because of their ability to produce high quality
molds at high production rates. Disamatic molding machines are used by most of
the Company's
 
                                       48
   52
 
direct competitors. Although the Company was not the first foundry to acquire
Disamatic molding machines, it has significantly enhanced the equipment's range
of production by combining it with core-setting capabilities which exceed those
of most foundries. To further improve upon the productivity of the Disamatic
molding machines, the Company has recently increased the length of two of its
cooling lines, making each line among the longest lines in the world for
comparable Disamatic equipment. This extension allows the Company to run its
machines at higher production rates while providing sufficient inmold cooling
time prior to mold shakeout to facilitate the production of high quality
castings. As a result of these and other similar efforts, the Company has been
able to increase productivity as measured in the number of molds per hour.
Additionally, from 1992 to 1997, the Company reduced employee hours per ton from
14.8 to 9.0.
 
     The Company also achieves productivity gains by improving upon the
individual steps of the casting process such as reducing the amount of time
required to make a pattern change to produce a different casting product. The
reduced time permits it to profitably produce castings in medium volume
quantities on high volume, cost-effective equipment such as the Disamatic
molding machines. Additionally, extensive effort in real time process controls
permits the Company to produce a consistent, dimensionally accurate casting
product which requires less time and effort in the final processing stages of
production. This accuracy contributes significantly to the Company's
manufacturing efficiency.
 
     Due to the Company's efforts to improve manufacturing productivity, as well
as increased operating leverage, improved pricing and a shift to higher
value-added industrial products, from fiscal 1992 to 1997 the Company's
operating margins have increased from 5.4% to 18.8%. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
HARTLEY CONTROLS
 
     Hartley Controls, a wholly owned subsidiary of the Company, engineers,
manufactures and sells customized sand control systems, which are an essential
part of the casting process, to other iron foundries. The sand molding media
used in all high production iron foundries is a critical element in determining
the mold quality. Exacting and consistent control of this sand with respect to
moisture and chemical additives is an essential element for process control, and
relates directly to casting quality, scrap rate and the ability to produce
complex molds for highly engineered castings. Hartley Controls is a major United
States supplier of sand control systems, with over 300 installations since 1986.
Hartley Controls has made investments in process technology and has several
patented technologies related to sand systems, including the "Automatic Moisture
Controllers," the "Even-Flo Bin," the "Automatic Compactibility Tester," the
"Automatic Bond Determinator," the "Green Sand Reconditioner" and the "Sandman."
Sales of these sand systems and other products represented approximately 4% of
the Company's net sales for 1997.
 
     In addition, Hartley Controls has recently expanded overseas and after only
three years has become a significant supplier of sand control systems in the
United Kingdom. Hartley Controls is the only manufacturer to supply control
systems in the United Kingdom for all brands of foundry sand mixers. Hartley
Controls also currently exports sand control systems to India, with further
expansion planned through a joint venture scheduled for the second quarter of
calendar 1997. Hartley Controls provides the Company access to the newest
technology in sand control as it becomes available.
 
QUALITY ASSURANCE
 
     Constant testing and monitoring of the manufacturing process is important
to maintain product quality. The Company has adopted sophisticated quality
assurance techniques and policies for its manufacturing operations. During and
after the casting process, the Company performs numerous tests, including
tensile, proof-load, radiography, ultrasonic, magnetic particle and chemical
analysis. The Company utilizes statistical process controls to measure and
control significant process variables and casting dimensions. The results of
this testing are documented in metallurgical
 
                                       49
   53
 
certifications which are provided with each shipment to most industrial
customers. The Company strives to maintain systems that provide for continuous
improvement of operations and personnel, emphasize defect prevention and reduce
variation and waste in all areas.
 
MANUFACTURING FACILITIES, EQUIPMENT AND PROPERTIES
 
     The Company's headquarters and two foundries are located in Neenah,
Wisconsin. The first manufacturing foundry, Plant 2, produces gray and ductile
iron castings and is equipped with one BMD air impulse molding line, two Hydro
slinger cope and drag molding units, and one 2070 Type B Disamatic molding
machine. The annual rated capacity for Plant 2 is 116,000 gst (good salable
tons). The second manufacturing foundry, Plant 3, produces ductile iron castings
and is equipped with one 2013 Mark IV Disamatic molding machine and one 2070
Type B Disamatic molding machine. In July, 1995, the Company completed a program
in Plant 3 to gain efficiencies in material handling, labor utilization and
molding line productivity. The annual rated capacity for Plant 3 is
approximately 71,000 gst. Industrial and municipal castings are produced in both
plants. Rated capacity is based on an assumed product mix and, due to the
Company's current industrial product mix, which includes numerous complex
castings, practical capacity is currently approximately 5% to 6% less than rated
capacity. The Company owns seven and leases six distribution and sales centers.
In early 1994, the Company closed Plant 1, its oldest and lowest capacity plant,
which was primarily producing large castings for HVAC Systems. The Company
closed Plant 1 because of its decision to discontinue the low volume, highly
complex castings produced by Plant 1 and the significant capital expenditures
that would have been necessary to modernize its equipment and facilities.
 
DISTRIBUTION
 
     The Company sells a substantial amount of its municipal castings through
its network of two warehouses, nine distribution and sales centers and two other
sales offices. Industrial castings are shipped direct to customers from the
Company. For many municipal and a small portion of its industrial customers,
castings are delivered by Neenah Transport, a wholly owned subsidiary of the
Company, which operates a fleet of 29 tractors and 101 trailers that deliver
products throughout the Midwest. For sales outside of the Midwest, increased
transportation costs impact the ability of the Company to compete on a cost
basis. Neenah Transport also backhauls raw materials for use by the Company on
return trips. Neenah Transport is staffed with professional drivers who are
trained in service standards and product knowledge as representatives of the
Company. To the Company's knowledge, none of the Company's major heavy municipal
competitors have a captive transportation subsidiary. The Company believes
Neenah Transport's service and drivers provide another differentiating factor in
favor of the Company.
 
RAW MATERIALS
 
     The primary raw materials used by the Company to manufacture iron castings
are steel scrap, pig iron, metallurgical coke and silica sand. While there are
multiple suppliers for each of these commodities, the Company has single source
arrangements with its suppliers of each of these major raw materials, with the
exception of pig iron. Due to long standing relationships with each of its
suppliers, the Company believes that it will continue to be able to secure raw
materials from its suppliers at competitive prices. The primary energy sources
for the Company's operations, electricity and natural gas, are purchased through
utilities.
 
     Although the prices of all raw materials used by the Company vary, the
fluctuations in the price of steel scrap are the most significant to the
Company. The Company has arrangements with most of its industrial customers
which require the Company to adjust industrial casting prices to reflect scrap
price fluctuations. In periods of rapidly rising or falling scrap prices, these
adjustments will lag the current scrap price because they are generally based on
average market prices for prior periods, which periods vary by customer but are
generally no longer than six months. Castings are
 
                                       50
   54
 
generally sold to the heavy municipal market on a bid basis and, after a bid is
won, the price for the municipal casting subject to the bid generally cannot be
adjusted for raw material price increases. However, in most cases the Company
has been successful in obtaining higher municipal casting unit prices in
subsequent bids to compensate for rises in scrap prices in prior periods.
Rapidly fluctuating scrap prices may have a temporary adverse or positive effect
on the Company's results of operations. See "Risk Factors -- Raw Materials."
 
COMPETITION
 
     The markets for the Company's products are highly competitive. Competition
is based not only on price, but also on quality of product, range of capability,
level of service and reliability of delivery. The Company competes with numerous
independent and captive foundries, as well as with a number of foreign iron
foundries, including certain foundries located in India. The Company also
competes with several large domestic manufacturers whose products are made with
materials other than ductile and gray iron, such as steel or aluminum. The
industry consolidation that has occurred over the past 20 years has resulted in
a significant reduction in the number of smaller foundries and a rise in the
share of production by larger foundries, some of which have significantly
greater financial resources than the Company. Competition from India has had a
strong presence in the heavy municipal market and continues to be a factor,
primarily in the western and eastern coastal states, due in part to costs
associated with transportation. Such competition has receded over the past 18
months, primarily as a result of increased enforcement of emission controls. As
a result, Indian import volume has decreased and the price of Indian casting
products has risen. Additionally, foreign companies have been, and continue to
be, subject to antidumping and countervailing duty enforcement litigation which
the Company believes has had a negative effect on foreign companies' ability to
compete in the United States markets. There can be no assurance that these
factors will continue to mitigate the impact of foreign competition, or that the
Company will be able to maintain or improve its competitive position in the
markets in which it competes.
 
BACKLOG
 
     The Company's industrial business generally involves supplying all or a
portion of a customer's annual requirements for a particular casting. Industrial
customers generally order castings on a monthly basis. Orders for the heavy
municipal market are generally received for specific casting products and cover
a much larger range of castings. The Company's backlog at any given time
consists only of firm industrial and municipal orders. The Company's backlog was
26,750 tons at March 31, 1997 as compared to 25,500 tons at March 31, 1996. The
increase in backlog of approximately 5% was primarily the result of
strengthening in the medium- and heavy-duty truck market. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
EMPLOYEES
 
     As of March 31, 1997, the Company had 910 full time employees, of whom 710
were hourly employees and 200 were salaried employees. Of the 200 salaried
employees, 91 are in manufacturing and engineering, 61 are in sales and
marketing, 44 are in management and administration and four are in
transportation. The Local 121B of the Glass, Molders, Pottery, Plastics and
Allied Workers International Union AFL-CIO is the major bargaining agent for and
representative of 678 of the Company's hourly employees. The collective
bargaining agreement with Local 121B was reached on January 1, 1996 and expires
on December 31, 1998. The Independent Patternmakers Union of Neenah, Wisconsin
is the major bargaining agent for and representative of 32 of the Company's
hourly employees. The collective bargaining agreement with the Independent
Patternmakers Union was reached on January 1, 1995 and expires on December 31,
1997. The Company believes that it has a good relationship with its employees.

LITIGATION
 
     The Company is involved in routine litigation incidental to its business.
Such litigation is not, in the opinion of management, likely to have a material
adverse effect on the financial condition or results of operation of the
Company.
 
ENVIRONMENTAL MATTERS
 
     The Company's facilities are subject to federal, state and local laws and
regulations relating to the protection of the environment and worker health and
safety, including those relating to discharges to air, water and land, the
handling and disposal of solid and hazardous waste and the cleanup of properties
affected by hazardous substances. Such laws include the Federal Clean Air Act,
the Clean Water Act, the Resource Conservation and Recovery Act and the
Occupational Health and Safety Act. The Company believes that its operations
have been and are currently in substantial compliance with applicable
environmental laws, and that it has no liabilities arising under such
environmental laws, except as would not be expected to have a material adverse
effect on the Company's operations, financial condition or competitive position.
However, some risk of environmental liability and other costs is inherent in the
nature of the iron foundry business. The Company might in the future incur
significant costs to meet current or more stringent compliance, cleanup or other
obligations pursuant to environmental requirements. Such costs may include
expenditures related to remediation of historical releases or clean-up of
structures prior to demolition.
 
     Under the Federal Clean Air Act Amendments of 1990 ("CAA"), the
Environmental Protection Agency must establish maximum achievable control
technology ("MACT") standards for hazardous air pollutants emitted from iron
foundry operations by the year 2000. In addition, Wisconsin law imposes
requirements on emissions of air toxins from iron foundries and other
industries. Many of the regulations that will implement the CAA and Wisconsin
law have not yet been promulgated. Although it is not possible to estimate the
costs of complying with the regulations until they are issued, iron foundries,
including the Company, can be expected to incur significant costs over time to
comply with these federal and state regulations.

beneficial interest in the Company (the "Purchased Interests") and (b) the
Management Investors and certain other employees of the Company are expected to
be granted, over a five year period, options (the "Options") to purchase
additional Purchased Interests representing, in the aggregate, approximately a
two percent beneficial interest in the Company. The Options are expected to be
granted periodically and to vest and become exercisable upon (i) certain
threshold dates and/or (ii) the satisfaction of certain financial performance
tests.
 
     Upon the termination of employment with the Company, an employee's
Purchased Interests will be subject to certain repurchase provisions exercisable
by ACP Products, L.L.C. or its designees. The Purchased Interests obtainable
upon exercise of the Options are expected to be subject to rights and
restrictions similar to those of the Purchased Interests purchased at Closing.

consultation with the Board of Directors of the Company or a compensation
committee thereof.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
RELATIONSHIP WITH ACP HOLDING COMPANY
 
     ACP Products, L.L.C. holds all of the issued and outstanding shares of
capital stock of ACP Holding Company ("ACP Holdings"). ACP Holdings is the
parent company of Holdings, and thus indirectly owns 100% of the Common Stock of
the Company. James K. Hildebrand, who serves as the Chairman of the Board and
Chief Executive Officer of the Company, currently serves as President and Chief
Executive Officer of ACP Holdings and its principal operating subsidiary,
Advanced Cast Products, Inc. ("Advanced Cast"). After the Closing, Mr.
Hildebrand will devote substantial time to, and be partially compensated by,
Advanced Cast, in addition to his role with the Company. Advanced Cast also
produces iron castings for sale to the industrial medium- and heavy-duty truck
market, but it has not competed with the Company in the past in any significant
way and the Company does not anticipate that it will so compete with Advanced
Cast in the future.
 
SHAREHOLDER RELATIONSHIPS
 
     In connection with the Merger, the Management Investors and certain
institutional investors, including Citicorp Venture Capital, Ltd., became
parties to the Second Amended and Restated Limited Liability Agreement of ACP
Products, L.L.C., as amended (the "L.L.C. Agreement"). The L.L.C. Agreement
contains certain provisions with respect to the beneficial equity interests and
corporate governance of the Company. The L.L.C. Agreement provides that the
Investor Group and the Management Investors, as the only members of ACP
Products, L.L.C. holding beneficial interests in the Company, have the right to
direct all actions taken in respect of Holdings and the Company, including,
without limitation, appointing members of the Board of Directors of the Company
and of Holdings.
 
REGISTRATION RIGHTS AGREEMENT
 
     The Company entered into a registration rights agreement (the "Registration
Rights Agreement") with the Investor Group and the Management Investors.
Pursuant to the terms of the Registration Rights Agreement, certain holders of
the Company's Common Stock have the right to require the Company, at the
Company's sole cost and expense and subject to certain limitations, to register
under the Securities Act or list on any recognized stock exchange all or part of
the Common Stock beneficially owned by such holders (the "Registrable
Securities"). All such holders will be entitled to participate in all
registrations by the Company or other holders, subject to certain limitations.
In connection with all such registrations, the Company agreed to indemnify all
beneficial owners of Registrable Securities against certain liabilities,
including liabilities under the Securities Act and other applicable state or
foreign securities laws. Registrations pursuant to the Registration Rights
Agreement will be made, if applicable, on the appropriate registration form and
may be underwritten registrations.
 
                     DESCRIPTION OF SENIOR BANK FACILITIES
 
     The Company entered into a credit agreement (the "Credit Agreement") with
The Chase Manhattan Bank, as administrative agent and collateral agent (the
"Agent") and the lenders named therein (the "Lenders") that provide term loans
of $45.0 million and a revolving credit facility of $30.0 million. Chase
Securities Inc. acted as advisor and arranger in connection with the Senior Bank
Facilities (the "Arranger"). The following is a summary description of the
principal terms of the Credit Agreement, which will be available upon request
from the Company.
 
     Structure.  Loans under the Credit Agreement consist of (i) a term loan
(the "Tranche A Term Loan") in the amount of $20.0 million; (ii) a second term
loan (the "Tranche B Term Loan," and together with the Tranche A Term Loan, the
"Term Loans") in the amount of $25.0 million and (iii) a
 
                                       57
   61
 
revolving credit facility (the "Revolving Credit Facility," and together with
the Term Loans, the "Senior Bank Facilities") in the amount of $30.0 million
subject to a borrowing base formula (of which $15.0 million will be available
for letters of credit). The Company used the Term Loans to provide a portion of
the funding necessary to consummate the Transactions, with the Revolving Credit
Facility being used for general corporate purposes in the ordinary course of the
Company's business.
 
     Security, Guaranty.  The obligations of the Company under the Senior Bank
Facilities will be unconditionally and irrevocably guaranteed, jointly and
severally, by Holdings and by each existing and subsequently acquired or
organized subsidiary of the Company. In addition, the Senior Bank Facilities and
the guarantees thereunder are secured by substantially all of the assets of the
Company and the guarantors (collectively, the "Collateral"), including but not
limited to (i) a first priority pledge of all the capital stock of the Company
and of each existing and subsequently acquired or organized subsidiary of the
Company and (ii) perfected first priority security interests in, and mortgages
on, substantially all tangible and intangible assets of the Company and the
guarantors (including but not limited to accounts receivable, documents,
inventory, equipment, intellectual property, general intangibles, real property,
cash and cash accounts and proceeds of the foregoing) in each case subject to
certain limited exceptions.
 
     Availability.  The availability of the Senior Bank Facilities are subject
to various conditions precedent typical of bank loans including, among other
things, the absence of any material adverse change on the part of the Company.
The full amount of the Term Loans must be drawn in a single drawing at the
Closing of the Transactions and amounts repaid or prepaid under the Term Loans
may not be reborrowed. Amounts under the Revolving Credit Facility are available
on a revolving basis, subject to a borrowing base comprised of percentages of
the Company's eligible accounts receivable and eligible inventory. As of March
31, 1997, on a pro forma basis after giving effect to the Offering, the other
Transactions, and the application of the proceeds therefrom as well as such
borrowing base limitations and $0.6 million of outstanding letters of credit,
the Company estimates it would have had the ability to borrow approximately
$24.8 million under the Revolving Credit Facility.
 
     Amortization, Interest.  The Tranche A Term Loan is repayable in quarterly
principal payments over five years totalling $4.0 million per year and will bear
interest at a rate per annum equal (at the Company's option) to: (i) an adjusted
London inter-bank offered rate ("Adjusted LIBOR") plus 2.5% or (ii) an Alternate
Base Rate (equal to the highest of the Agent's prime rate, a certificate of
deposit rate plus 1% and the Federal Funds effective rate plus 1/2 of 1%) plus
1.5%, in each case subject to certain reductions based on the Company's
financial performance. The Tranche B Term Loan is repayable in quarterly
principal payments over seven years, totalling $1.0 million per year for the
first five years and $10.0 million per year for the last two years, and will
bear interest at a rate per annum equal (at the Company's option) to: (i)
Adjusted LIBOR plus 3.0% or (ii) the Alternate Base Rate plus 2.0%. The
Revolving Credit Facility will be a five year facility and will bear interest at
a rate per annum equal (at the Company's option) to: (i) Adjusted LIBOR plus
2.5% or (ii) the Alternate Base Rate plus 1.5%, in each case subject to certain
reductions based on the Company's financial performance. Amounts under the
Senior Bank Facilities not paid when due bear interest at a default rate equal
to 2.0% above the otherwise applicable rate.
 
     Prepayments.  The Senior Bank Facilities permit the Company to prepay loans
and to permanently reduce revolving credit commitments, in whole or in part, at
any time. In addition, the Company is required to make mandatory prepayments of
Term Loans, subject to certain exceptions, in amounts equal to (i) 50% of
consolidated excess cash flow of Holdings, the Company and its subsidiaries; and
(ii) 100% of the net cash proceeds of certain dispositions of assets or
issuances of debt or equity of the Company or any of its subsidiaries. Mandatory
and optional prepayments of the Term Loans will be allocated pro rata between
the Tranche A Term Loan and the Tranche B Term Loan and applied pro rata against
the remaining scheduled amortization payments of such Term Loans, except that,
so long as the Tranche A Term Loan is outstanding, the Lenders
 
                                       58
   62
 
participating in the Tranche B Term Loan will have the right to refuse mandatory
prepayments, in which case such prepayments will be applied to the Tranche A
Term Loan. Any prepayment of Adjusted LIBOR loans other than at the end of an
interest period will be subject to reimbursement of breakage costs.
 
     Fees.  The Company is required to pay the lenders, on a quarterly basis, a
commitment fee equal to 1/2 of 1% per annum on the undrawn portion of the
commitments, subject to reductions based upon the Company's financial
performance. The Company is also required to pay (i) a per annum letter of
credit fee equal to the applicable margin from time to time for Adjusted LIBOR
loans under the Revolving Credit Facility on the aggregate face amount of
outstanding letters of credit under the Revolving Credit Facility, (ii) a
fronting bank fee for the letter of credit issuing bank, (iii) annual
administration fees, and (iv) agent, arrangement and other similar fees.
 
     Covenants.  The Senior Bank Facilities contain a number of covenants that,
among other things, restrict the ability of the Company and its subsidiaries to
dispose of assets, incur additional indebtedness, incur guarantee obligations,
prepay other indebtedness or amend other debt instruments, pay dividends, create
liens on assets, enter into sale and leaseback transactions, make investments,
loans or advances, make acquisitions, engage in mergers or consolidations,
change the business conducted by the Company or its subsidiaries, make capital
expenditures, or engage in certain transactions with affiliates and otherwise
restrict certain corporate activities. In addition, under the Senior Bank
Facilities, the Company is required to comply with specified financial ratios
and tests, including minimum interest coverage ratios, maximum leverage ratios
and minimum net worth tests.
 
     The Senior Bank Facilities also contain provisions that prohibit any
modification of the Indenture in any manner adverse to the Lenders and that will
limit the Company's ability to refinance or otherwise prepay the Notes without
the consent of such Lenders.
 
     Events of Default.  The Senior Bank Facilities contain customary events of
default, including payment defaults, breach of representations and warranties,
covenant defaults, cross-defaults and cross-acceleration to certain other
indebtedness, certain events of bankruptcy and insolvency, ERISA events,
judgment defaults, actual or asserted invalidity of any security interest and
change of control.
 
                              DESCRIPTION OF NOTES
 
GENERAL
 
     The form and terms of the New Notes are the same as the form and terms of
the Old Notes except that (i) the New Notes will have been registered under the
Securities Act and thus will not bear restrictive legends restricting their
transfer pursuant to the Securities Act and (ii) holders of New Notes will not
be entitled to certain rights of holders of the Old Notes under the Registration
Rights Agreement which will terminate upon the consummation of the Exchange
Offer. The Old Notes have been, and the New Notes are to be, issued under an
Indenture, dated as of             (the "Indenture"), among the Company, the
Guarantor Subsidiaries and United States Trust Company of New York, as Trustee
(the "Trustee").
 
     The following summary of certain provisions of the Indenture and the Notes
does not purport to be complete and is subject to, and is qualified in its
entirety by reference to, all the provisions of the Indenture, including the
definitions of certain terms therein and those terms made a part thereof by the
Trust Indenture Act of 1939, as amended ("TIA"). Capitalized terms used herein
and not otherwise defined have the meanings set forth in the section "-- Certain
Definitions" below.
 
     Principal of, premium, if any, and interest on the Notes will be payable,
and the Notes may be exchanged or transferred, at the office or agency of the
Company in the Borough of Manhattan, the City of New York (which initially shall
be the corporate trust office of the Trustee at 114 West 47th

Street, New York, N.Y. 10036, Attn: Gerard Ganey), except that, at the option of
the Company, payment of interest may be made by check mailed to the registered
holders of the Notes at their registered addresses.
 
     The Notes may be issued only in fully registered form, without coupons, in
denominations of $1,000 and any integral multiple of $1,000. 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 transfer tax or
other similar governmental charge payable in connection therewith.
 
TERMS OF THE NOTES
 
     The Notes are unsecured senior subordinated obligations of the Company,
limited to $150.0 million aggregate principal amount, and will mature on May 1,

the Applicable Premium. Each Holder of Notes will also have certain rights to
require the Company to purchase such Notes upon the occurrence of a Change of
Control. See "-- Change of Control" below.

SELECTION
 
     In the case of any partial redemption, selection of the Notes for
redemption will be made by the Trustee on a pro rata basis, by lot or by such
other method as the Trustee in its sole discretion shall deem to be fair and
appropriate, although no Note of $1,000 in original principal amount or less
will be redeemed in part. If any Note is to be redeemed in part only, the notice
of redemption relating to such Note shall state the portion of the principal
amount thereof to be redeemed. A new Note in principal amount equal to the
unredeemed portion thereof will be issued in the name of the Holder thereof upon
cancellation of the original Note.
 
RANKING
 
     The indebtedness evidenced by the Notes is unsecured Senior Subordinated
Indebtedness of the Company. The payment of the principal of, premium (if any)
and interest on the Notes is subordinate in right of payment, as set forth in
the Indenture, to all existing and future Senior Indebtedness of the Company,
ranks pari passu in right of payment with all existing and future Senior
Subordinated Indebtedness of the Company and is senior in right of payment to
all existing and future Subordinated Obligations of the Company. The Notes will
also be effectively subordinated to any Secured Indebtedness of the Company to
the extent of the value of the assets securing such indebtedness. However,
payment from the money or the proceeds of U.S. Government Obligations held in
any defeasance trust described under "Defeasance" below is not subordinated to
any Senior Indebtedness or subject to the restrictions described herein.
 
     The indebtedness evidenced by a Subsidiary Guaranty is unsecured Senior
Subordinated Indebtedness of the Guarantor Subsidiary issuing such Subsidiary
Guaranty. The payment of a Subsidiary Guaranty is subordinate in right of
payment, as set forth in the Indenture, to all existing and future Senior
indebtedness of such Guarantor Subsidiary, ranks pari passu in right of payment
with the existing and future Senior Subordinated Indebtedness of such Guarantor
Subsidiary and will be senior in right of payment to all existing and future
Subordinated Obligations of such Guarantor Subsidiary. Each Subsidiary Guaranty
is also effectively subordinated to any Secured Indebtedness of the Guarantor
Subsidiary to the extent of the value of the assets securing such indebtedness.
 
     As of March 31, 1997, after giving pro forma effect to the Transactions,
the Offering and the application of the proceeds therefrom, the Company would
have had outstanding $46.0 million of Senior Indebtedness, excluding $0.6
million of outstanding letters of credit, no Senior Subordinated Indebtedness
other than the Indebtedness represented by the Notes, and no Indebtedness that
is subordinate and junior in right of repayment to the Indebtedness represented
by the Notes. As of March 31, 1997, and after giving effect to the Transactions,
the Offering and the application of the proceeds therefrom, as well as borrowing
base limitations and $0.6 million of outstanding letters of credit, the Company
estimates it would have had the ability to borrow approximately $24.8 million
under the Revolving Credit Facility. Although the Indenture contains limitations
on the amount of additional Indebtedness that the Company and its Guarantor
Subsidiaries may incur, under certain circumstances the amount of such
Indebtedness could be substantial and, in any case, such Indebtedness may be
Senior Indebtedness of the Company or a Guarantor Subsidiary, as the case may
be. See "Certain Covenants -- Limitation on Indebtedness" below.
 
     "Senior Indebtedness" of the Company means all principal of, premium (if
any), accrued interest (including interest accruing on or after the filing of
any petition in bankruptcy or for reorganization relating to the Company whether
or not a claim for post-filing interest is allowed in such proceedings), fees,
charges, expenses, reimbursement obligations, guarantees and other amounts owing
with respect to all Indebtedness of the Company, and including all Bank
Indebtedness, whether outstanding on the Issue Date or thereafter incurred,
unless in the instrument creating or evidencing the same or pursuant to which
the same is outstanding it is expressly provided that such obligations are not
superior in right of payment to the Notes; provided, however, that Senior
 
                                       61
   65
 
Indebtedness shall not include (1) any obligation of the Company to any
Subsidiary, (2) any liability for federal, foreign, state, local or other taxes
owed or owing by the Company, (3) any accounts payable or other liability to
trade creditors arising in the ordinary course of business (including Guarantees
thereof or instruments evidencing such liabilities), (4) any Indebtedness or
obligation of the Company which is subordinate or junior in any respect (other
than as a result of the Indebtedness being unsecured) to any other Indebtedness
or obligation of the Company, including any Senior Subordinated Indebtedness and
any Subordinated Obligations, (5) any obligations with respect to any Capital
Stock or (6) any Indebtedness Incurred in violation of the Indenture. "Senior
Indebtedness" of any Guarantor Subsidiary has a correlative meaning.
 
     Only Indebtedness of the Company or a Guarantor Subsidiary that is Senior
Indebtedness will rank senior to the Notes and the relevant Subsidiary Guaranty
in accordance with the provisions of the Indenture. The Notes and each
Subsidiary Guaranty in all respects ranks pari passu with all other Senior
Subordinated Indebtedness of the Company and the relevant Guarantor Subsidiary,
respectively. The Company and each Guarantor Subsidiary has agreed in the
Indenture that it will not incur, directly or indirectly, any Indebtedness which
is subordinate or junior in ranking in any respect to Senior Indebtedness unless
such Indebtedness is Senior Subordinated Indebtedness, or is expressly
subordinated in right of payment to Senior Subordinated Indebtedness. Unsecured
Indebtedness of the Company or a Guarantor Subsidiary is not deemed to be
subordinated or junior to Secured Indebtedness, as the case may be, merely
because it is unsecured.
 
     The Company may not pay principal of, or premium (if any) or interest on,
the Notes or make any deposit pursuant to the provisions described under
"-- Defeasance" below, and may not otherwise purchase, redeem or otherwise
retire any Notes other than from funds held in a defeasance trust pursuant to
the provisions described under "-- Defeasance" below (collectively, "pay the
Notes"), if (i) any Senior Indebtedness of the Company is not paid when due or
(ii) any other default on Senior Indebtedness of the Company occurs and the
maturity of such Senior Indebtedness is accelerated in accordance with its terms
unless, in either case, the default has been cured or waived and any such
acceleration has been rescinded or such Senior Indebtedness has been paid in
full. However, the Company may pay the Notes without regard to the foregoing if
the Company and the Trustee receive written notice approving such payment from
the Representative of the holders of the Senior Indebtedness with respect to
which either of the events set forth in clause (i) or (ii) of the immediately
preceding sentence has occurred and is continuing. During the continuance of any
default (other than a default described in clause (i) or (ii) of the second
preceding sentence) with respect to any Designated Senior Indebtedness pursuant
to which the maturity thereof may be accelerated immediately without further
notice (except such notice as may be required to effect such acceleration) or
the expiration of any applicable grace periods, the Company may not pay the
Notes for a period (a "Payment Blockage Period") commencing upon the receipt by
the Trustee (with a copy to the Company) of written notice (a "Blockage Notice")
of such default from the Representative of the holders of the Designated Senior
Indebtedness specifying an election to effect a Payment Blockage Period and
ending 179 days thereafter (or earlier if such Payment Blockage Period is
terminated (i) by written notice to the Trustee and the Company from the Person
or Persons who gave such Blockage Notice, (ii) because the default giving rise
to such Blockage Notice is no longer continuing or (iii) because such Designated
Senior Indebtedness has been repaid in full). Notwithstanding the provisions
described in the immediately preceding sentence, unless the holders of such
Designated Senior Indebtedness have, or the Representative of such holders has,
accelerated the maturity of such Designated Senior Indebtedness, the Company may
resume payments on the Notes after the end of such Payment Blockage Period,
including any missed payments. Not more than one Blockage Notice may be given in
any consecutive 360-day period, irrespective of the number of defaults with
respect to Designated Senior Indebtedness during such period. However, if any
Blockage Notice within such 360-day period is given by or on behalf of any
holders of Designated Senior Indebtedness other than the Bank Indebtedness, the
Representative of the Bank Indebtedness may give another Blockage Notice within
such period. In no event, however, may the total number of days during which any
 
                                       62
   66
 
Payment Blockage Period or Periods is in effect exceed 179 days in the aggregate
during any 360 consecutive day period.
 
     Upon any payment or distribution of the assets of the Company upon a total
or partial liquidation or dissolution or reorganization of or similar proceeding
relating to the Company or its property, the holders of Senior Indebtedness of
the Company will be entitled to receive payment in full of the Senior
Indebtedness of the Company before the Noteholders are entitled to receive any
payment and until the Senior Indebtedness of the Company is paid in full, any
payment or distribution to which Noteholders would be entitled but for the
subordination provisions of the Indenture will be made to holders of the Senior
Indebtedness of the Company as their respective interests may appear. If a
payment or distribution is made to Noteholders that due to the subordination
provisions should not have been made to them, such Noteholders are required to
hold such payment or distribution in trust for the holders of Senior
Indebtedness and pay it over to them as their respective interests may appear.
 
     If payment of the Notes is accelerated because of an Event of Default, the
Company or the Trustee shall promptly notify the holders of the Designated
Senior Indebtedness or the Representative of such holders of the acceleration.
The Company may not pay the Notes until five Business Days after such holders or
the Representative of the holders of the Designated Senior Indebtedness receive
notice of such acceleration and, thereafter, may pay the Notes only if the
subordination provisions of the Indenture otherwise permit payment at that time.
 
     The terms of the subordination provisions described above with respect to
the Company's obligations under the Notes apply equally to a Guarantor
Subsidiary and the obligations of such Guarantor Subsidiary under its Subsidiary
Guaranty.
 
     By reason of such subordination provisions contained in the Indenture, in
the event of insolvency, creditors of the Company or a Guarantor Subsidiary who
are holders of Senior Indebtedness of the Company or a Guarantor Subsidiary, as
the case may be, may recover more, ratably, than the Noteholders, and creditors
of the Company who are not holders of Senior Indebtedness of the Company or of
Senior Subordinated Indebtedness (including the Notes) may recover less,
ratably, than holders of Senior Indebtedness of the Company.
 
SUBSIDIARY GUARANTIES
 
     Each of Neenah Foundry Company, Hartley Controls Corporation and Neenah
Transport, Inc. (the "Initial Guarantors," and together with all future issuers
of Subsidiary Guaranties, the "Guarantor Subsidiaries") jointly and severally as
primary obligors and not merely as sureties, irrevocably Guarantee on an
unsecured senior subordinated basis the performance and punctual payment when
due, whether at Stated Maturity, by acceleration or otherwise, of all
obligations of the Company under the Indenture and the Notes, whether for
payment of principal of or interest on the Notes, expenses, indemnification or
otherwise (all such obligations guaranteed by the Guarantor Subsidiaries being
herein called the "Guaranteed Obligations"). The Guarantor Subsidiaries have
agreed to pay, in addition to the amount stated above, any and all expenses
(including reasonable counsel fees and expenses) incurred by the Trustee or the
Holders in enforcing any rights under the Subsidiary Guaranties. Each Subsidiary
Guaranty is limited in amount to an amount not to exceed the maximum amount that
can be Guaranteed by the applicable Guarantor Subsidiary without rendering such
Subsidiary Guaranty voidable under applicable law relating to fraudulent
conveyance or fraudulent transfer or similar laws affecting the rights of
creditors generally. On or after the Issue Date, the Company will cause each
Restricted Subsidiary which Incurs Indebtedness to execute and deliver to the
Trustee a supplemental indenture pursuant to which such Restricted Subsidiary
will Guarantee payment of the Notes. See "Certain Covenants -- Future Guarantor
Subsidiaries" below.
 
     Each Subsidiary Guaranty is a continuing guarantee and shall (a) remain in
full force and effect until payment in full of all the Guaranteed Obligations,
(b) be binding upon each Guarantor
 
                                       63
   67
 
Subsidiary and (c) enure to the benefit of and be enforceable by the Trustee,
the Holders and their successors, transferees and assigns.
 
     A Subsidiary Guaranty will be released upon the sale of the capital stock,
or all or substantially all of the assets, of the applicable Guarantor
Subsidiary if such sale is made in compliance with the Indenture.
 
     Each of the Company's Guarantor Subsidiaries also Guarantee Indebtedness of
the Company Incurred under the terms of the Senior Bank Facilities. Because the
operations of the Company are conducted through its Subsidiaries, and the
Guaranties issued by the Guarantor Subsidiaries are secured by pledges of
substantially all the assets of the Guarantor Subsidiaries, the Notes
effectively subordinated to creditors of the Company under the Senior Bank
Facilities. See "Risk Factors -- Holding Company Structure."
 
CHANGE OF CONTROL
 
     Upon the occurrence of any of the following events (each a "Change of
Control"), each Holder will have the right to require the Company to repurchase
all or any part of such Holder's Notes at a purchase price in cash equal to 101%
of the principal amount thereof, plus accrued and unpaid interest, if any, to
the date of purchase (subject to the right of Holders of record on the relevant
record date to receive interest due on the relevant interest payment date),
pursuant to the offer described below and the other procedures set forth in the
Indenture; provided, however, that notwithstanding the occurrence of a Change of
Control, the Company shall not be obligated to purchase the Notes pursuant to
this covenant in the event that it has exercised its rights to redeem all of the
Notes as described under "-- Optional Redemption":
 
          (a) prior to the earlier to occur of the first public offering of
     Voting Stock of ACP Holdings, Holdings or the Company, the Permitted
     Holders cease to be entitled (by "beneficial ownership" (as defined in
     Rules 13d-3 and 13d-5 under the Exchange Act) of Voting Stock, contract or
     otherwise) to elect or cause the election of directors of the Company
     having a majority of the total voting power of the Board of Directors of
     the Company, whether as a result of issuance of securities of the Company,
     any merger, consolidation, liquidation or dissolution of the Company, any
     direct or indirect transfer of securities by any Permitted Holder or
     otherwise (for purposes of this clause (a), the Permitted Holders shall be
     deemed to beneficially own any Voting Stock of a corporation (the
     "specified corporation") held by any other corporation (the "parent
     corporation") so long as one or more of the Permitted Holders beneficially
     own (as so defined), directly or indirectly, in the aggregate a majority of
     the voting power of the Voting Stock of the parent corporation);
 
          (b) after the first public offering of Voting Stock of ACP Holdings,
     Holdings or the Company, any person or group (as such terms are used in
     Sections 13(d) and 14(d) of the Exchange Act), other than one or more of
     the Permitted Holders, is or becomes the beneficial owner (as defined in
     clause (a) above), directly or indirectly, of Voting Stock that represents
     more than 40% of the aggregate ordinary voting power of all classes of the
     Voting Stock of ACP Holdings, Holdings or the Company voting together as a
     single class, and either (x) the Permitted Holders beneficially own (as
     defined in clause (a) above), directly or indirectly, in the aggregate
     Voting Stock that represents a lesser percentage of the aggregate ordinary
     voting power of all classes of the Voting Stock of ACP Holdings, Holdings,
     or the Company as the case may be, voting together as a single class, than
     such other person or group and are not entitled (by voting power, contract
     or otherwise) to elect directors of ACP Holdings, Holdings or the Company
     having a majority of the total voting power of the board of directors of
     ACP Holdings, Holdings or the Company, as the case may be, or (y) such
     other person or group is entitled to elect directors of ACP Holdings,
     Holdings or the Company having a majority of the total voting power of the
     board of directors of ACP Holdings, Holdings or the Company;
 
                                       64
   68
 
          (c) after the first public offering of Voting Stock of ACP Holdings,
     Holdings or the Company, during any period of not greater than two
     consecutive years beginning after the Issue Date, individuals who at the
     beginning of such period constituted the board of directors of ACP
     Holdings, Holdings or the Company, as the case may be (together with any
     new directors whose election by such board of directors, or whose
     nomination for election by shareholders was approved by the Permitted
     Holders or by such board of directors, in each case by a vote of a majority
     of the directors of ACP Holdings, Holdings or the Company, as the case may
     be, then still in office who were either directors at the beginning of such
     period or whose election or nomination for election was previously so
     approved), cease for any reason to have a majority of the total voting
     power of the board of directors of ACP Holdings, Holdings or the Company,
     as the case may be; or
 
          (d) any sale, lease, or other transfer (in one transaction or in a
     series of related transactions) is made by the Company or its Restricted
     Subsidiaries of all or substantially all of the consolidated assets of the
     Company and its Restricted Subsidiaries to any Person.
 
     Within 30 days following any Change of Control, the Company shall mail a
notice to each Holder with a copy to the Trustee stating, among other things:
(1) that a Change of Control has occurred and that such Holder has the right to
require the Company to purchase all or any portion of such Holder's Notes at a
purchase price in cash equal to 101% of the principal amount thereof, plus
accrued and unpaid interest, if any, to the date of repurchase (subject to the
right of Holders of record on a record date to receive interest on the relevant
interest payment date); (2) the circumstances and relevant facts and financial
information regarding such Change of Control; (3) the repurchase date (which
shall be no earlier than 30 days nor later than 60 days from the date such
notice is mailed); and (4) the instructions determined by the Company,
consistent with this covenant, that a Holder must follow in order to have its
Notes or any portion thereof purchased.
 
     The Company will comply, to the extent applicable, with the requirements of
Section 14(e) of the Exchange Act and any other securities laws or regulations
in connection with the repurchase of Notes pursuant to this covenant. To the
extent that the provisions of any securities laws or regulations conflict with
provisions of this covenant, the Company will comply with the applicable
securities laws and regulations and will not be deemed to have breached its
obligations described above by virtue thereof.
 
     The Change of Control purchase feature is a result of negotiations between
the Company and the Initial Purchasers. Management has no present intention to
engage in a transaction involving a Change of Control, although it is possible
that the Company or Holdings would decide to do so in the future. Subject to the
limitations discussed below, the Company could, in the future, enter into
certain transactions, including acquisitions or other recapitalizations, that
would not constitute a Change of Control under the Indenture, but that could
increase the amount of indebtedness outstanding at such time or otherwise affect
the Company's capital structure or credit ratings.
 
     The occurrence of a Change of Control would constitute a default under the
Senior Bank Facilities. Future Senior Indebtedness of the Company may contain
prohibitions of certain events which would constitute a Change of Control or
require such Senior Indebtedness to be repurchased upon a Change of Control.
Moreover, the exercise by the Holders of their right to require the Company to
repurchase the Notes could cause a default under such Senior Indebtedness, even
if the Change of Control itself does not, due to the financial effect of such
repurchase on the Company. Finally, the Company's ability to pay cash to the
Holders upon a repurchase may be limited by the Company's then existing
financial resources. There can be no assurance that sufficient funds will be
available when necessary to make any repurchases required in connection with a
Change of Control. The Company's failure to purchase the Notes in connection
with a Change of Control would result in a default under the Indenture.

CERTAIN COVENANTS
 
     The Indenture will contain covenants including, among others, the
following:
 
     Limitation on Indebtedness.  (a) The Company will not, and will not permit
any Restricted Subsidiary to, Incur any Indebtedness (other than pursuant to the
following paragraph (b)) unless on the date of such Incurrence the Consolidated
Coverage Ratio exceeds 2.00 to 1.
 
     (b) Notwithstanding the foregoing paragraph (a), the Company and its
Restricted Subsidiaries may Incur the following Indebtedness:

     principal amount outstanding of up to $45.0 million less (A) the amount of
     any scheduled principal payments thereon and (B) the aggregate amount of
     all repayments of principal actually made thereunder since the Issue Date

     outstanding not in excess of the greater of $35.0 million and the Borrowing
     Base in effect from time to time (in each case less the aggregate amount of
     all repayments of principal actually made thereunder since the Issue Date
     with Net Available Cash from Asset Dispositions pursuant to clause
     (a)(iii)(A) of the covenant described under "-- Limitation on Sales of
     Assets and Subsidiary Stock");
 
          (iii) Indebtedness of the Company owing to and held by any Wholly
     Owned Subsidiary or Indebtedness of a Restricted Subsidiary owing to and
     held by the Company or any Wholly Owned Subsidiary; provided, however, that
     any subsequent issuance or transfer of any Capital Stock or any other event
     which results in any such Wholly Owned Subsidiary ceasing to be a Wholly
     Owned Subsidiary or any subsequent transfer of any such Indebtedness
     (except to the Company or a Wholly Owned Subsidiary) will be deemed, in
     each case, to constitute the Incurrence of such Indebtedness by the issuer
     thereof;
 
          (iv) Indebtedness of the Company represented by the Notes;
 
          (v) any Indebtedness of the Company and its Restricted Subsidiaries
     (other than the Indebtedness described in clauses (i), (ii) or (iii) above)
     outstanding on the Issue Date;
 
          (vi) Indebtedness of the Company and its Restricted Subsidiaries (A)
     in respect of judgment, appeal, surety, performance and other like bonds,

     do not secure other Indebtedness and (B) under Commodity Agreements,
     Currency Agreements and Interest Rate Agreements that are designed to
     protect the Company and its Restricted Subsidiaries against fluctuations in
     commodity prices (for raw materials used by them), interest rates or
     currency exchange rates and not for the purposes of speculation;
 
          (vii) Indebtedness represented by Guarantees by the Company of
     Indebtedness of a Restricted Subsidiary, or in respect of letters of credit
     provided by the Company to support such Indebtedness, or Guarantees by a
     Restricted Subsidiary of Indebtedness of the Company or a Restricted
     Subsidiary, or in respect of letters of credit provided by a Restricted
     Subsidiary to support such Indebtedness; provided, however, that only
     Indebtedness that is Incurred in compliance with this covenant may be
     guaranteed pursuant to this clause (vii);
 
          (viii) Purchase Money Indebtedness, industrial revenue bonds or
     similar Indebtedness and Capitalized Lease Obligations of the Company and
     its Restricted Subsidiaries in an aggregate principal amount at any time
     outstanding not in excess of 10% of Total Assets;
 
          (ix) Indebtedness of the Company or any Restricted Subsidiary
     consisting of guarantees, indemnities or obligations in respect of purchase
     price adjustments, in connection with the
 
                                       66
   70

     indemnification obligations to such Person, in each case Incurred in the
     ordinary course of business;
 
          (xii) Indebtedness of the Company consisting of guarantees of up to an

     purchased in anticipation of satisfying a sinking fund obligation,
     principal installment or final maturity, in each case due within one year
     of the date of acquisition); or
 
          (iv) make any Investment (other than a Permitted Investment) in any
     Person (any such dividend, distribution, purchase, redemption, repurchase,
     defeasance, other acquisition, retirement, Investment or payment being
     herein referred to as a "Restricted Payment") if at the time the Company or
     such Restricted Subsidiary makes such Restricted Payment: (1) a Default

     Company could not Incur at least $1.00 of additional Indebtedness under
     paragraph (a) of the covenant described under "-- Limitation on
     Indebtedness"; or (3) the aggregate amount of such Restricted Payment and
     all other Restricted Payments (the amount so expended, if other than in
     cash, to be determined in good faith by the Board of Directors, whose
     determination will be conclusive and evidenced by a resolution of the Board
     of Directors) declared or made subsequent to the Issue Date would exceed
     the sum of:
 
             (A) 50% of the Consolidated Net Income accrued during the period
        (treated as one accounting period) from the Issue Date to the end of the
        most recent fiscal quarter ending at least 45 days prior to the date of

        (including the fair market value (as determined in good faith by the
        Board of Directors, whose determination will be conclusive and evidenced
        by a resolution of the Board of Directors) of property received by the
        Company; provided, however, that such property is related, ancillary or
        complementary to any business of the Company and the Restricted
        Subsidiaries conducted on the Issue Date) as a capital contribution or
        from the issue or sale of Capital Stock (other than Disqualified Stock)
        of the Company or Holdings subsequent to the Issue Date (other than an
        issuance or sale to a Subsidiary of the Company or an employee stock
        ownership plan or other trust established by the Company or any of its
        Subsidiaries to the extent the purchase by such plan or trust is
        financed by Indebtedness of such plan or trust and for which the Company
        or a Subsidiary is liable, directly or indirectly, as a guarantor or
        otherwise (including by the making of cash contributions to such plan or
        trust which are used to pay interest or principal on such
        Indebtedness));
 
             (C) the amount by which Indebtedness of the Company or its
        Restricted Subsidiaries is reduced on the Company's balance sheet upon
        the conversion or exchange (other than by a Subsidiary) of any
        Indebtedness of the Company or its Restricted Subsidiaries issued
        subsequent to the Issue Date and convertible or exchangeable for Capital
        Stock (other than Disqualified Stock) of the Company (less the amount of
        any cash or other property (other than such Capital Stock) distributed
        by the Company or any Restricted Subsidiary upon such conversion or
        exchange) (including any such exchange pursuant to the exercise of a
        conversion right or privilege in connection with which cash is paid in
        lieu of the issuance of fractional shares or scrip);
 
             (D) the aggregate Net Cash Proceeds received subsequent to the
        Issue Date by the Company or Holdings (other than from any Restricted
        Subsidiary) upon the exercise of any options or warrants to purchase
        Capital Stock (other than Disqualified Stock) of the Company or
        Holdings; and
 
                                       68
   72
 
             (E) the amount equal to the net reduction in Investments in
        Unrestricted Subsidiaries resulting from (i) payments of dividends,
        repayments of the principal of loans, return of capital or advances or
        other transfers of assets to the Company or any Restricted Subsidiary
        from Unrestricted Subsidiaries or (ii) the redesignation of Unrestricted
        Subsidiaries as Restricted Subsidiaries (valued in each case as provided
        in the definition of "Investment") or the receipt of proceeds from the
        sale or other disposition of any portion of any Investment in an
        Unrestricted Subsidiary not to exceed, in the case of any Unrestricted
        Subsidiary, the amount of Investments previously made by the Company or
        any Restricted Subsidiary in such Unrestricted Subsidiary, which amount
        was included in the calculation of the amount of Restricted Payments.
 
     (b) The provisions of the foregoing paragraph (a) will not prohibit:
 
          (i) any purchase, redemption, retirement or other acquisition of
     Capital Stock or Subordinated Obligations of the Company made by exchange
     for, or out of the proceeds of the substantially concurrent sale of,
     Capital Stock of the Company (other than Disqualified Stock and other than
     Capital Stock issued or sold to a Subsidiary or an employee stock ownership
     plan or other trust established by the Company or any of its Subsidiaries
     to the extent the purchase by such plan or trust is financed by
     Indebtedness of such plan or trust and for which the Company or a
     Subsidiary is liable, directly or indirectly, as a guarantor or otherwise
     (including by the making of cash contributions to such plan or trust which
     are used to pay interest or principal on such Indebtedness)); provided,
     however, that (A) such purchase, redemption, retirement or other
     acquisition will be excluded in the calculation of the amount of Restricted
     Payments and (B) the Net Cash Proceeds from such sale to the extent so used
     will be excluded from clause (iv)(B) of paragraph (a) above;
 
        (ii) any purchase, defeasance, retirement, redemption or other

     for, or out of the proceeds of the substantially concurrent sale of,
     Indebtedness of the Company which is permitted to be Incurred pursuant to
     paragraph (b) of the covenant described under "-- Limitation on
     Indebtedness" or (B) Subordinated Obligations of a Restricted Subsidiary
     made by exchange for, or out of the proceeds of the substantially
     concurrent sale of, Indebtedness of any Restricted Subsidiary or the
     Company which is permitted to be Incurred pursuant to paragraph (b) of the
     covenant described under "-- Limitation of Indebtedness"; provided,
     however, that such purchase, defeasance, retirement, redemption or other
     acquisition will be excluded in the calculation of the amount of Restricted
     Payments;
 
          (iii) any purchase, redemption, retirement or other acquisition of
     Disqualified Stock made by exchange for, or out of the proceeds of the

     excluded in the calculation of the amount of Restricted Payments;
 
          (iv) any purchase or redemption of Subordinated Obligations from Net
     Available Cash to the extent permitted by the covenant described under

     purchase of all Notes tendered), any purchase, defeasance, retirement,
     redemption or other acquisition of Subordinated Obligations required
     pursuant to the terms thereof as a result of such Change of Control;
     provided, however, that such purchase, defeasance, retirement, redemption
     or other acquisition will be included in the calculation of the amount of
     Restricted Payments;
 
                                       69
   73
 
          (vi) dividends paid within 60 days after the date of declaration
     thereof if at such date of declaration such dividend would have complied
     with this covenant; provided, however, that such dividend will be included
     in the calculation of the amount of Restricted Payments;
 
          (vii) the repurchase, for cash or notes, of shares of, or options or
     warrants to purchase shares of, or payments to Holdings to enable Holdings
     to repurchase shares of, or options or warrants to purchase shares of,
     Capital Stock of Holdings, the Company or any of the Subsidiaries of the
     Company from present or former Management Investors in an amount not in

     of $250,000 in the aggregate;
 
          (ix) payments by the Company to Holdings to pay Federal, state and
     local taxes to the extent such taxes are attributable to the Company and
     its Restricted Subsidiaries; provided, however, that such payments will be
     excluded from the calculation of the amount of Restricted Payments;
 
          (x) loans, advances, dividends or distributions by the Company to
     Holdings to pay dividends on the common stock of Holdings following a
     Public Equity Offering of such stock; but only to the extent that such
     loans, advances, dividends or distributions do not exceed 6% per annum of
     the net proceeds received by the Company in such Public Equity Offering;
     provided, however, that the amount of such loans, advances, dividends or
     distributions will be included in the amount of Restricted Payments; or
 
          (xi) in each case to the extent such payments by Holdings are
     attributable to the Company and its Restricted Subsidiaries, payments by
     the Company to Holdings not to exceed an amount necessary to permit
     Holdings to (A) make payments in respect to its indemnification obligations
     owing to directors, officers or other Persons under Holding's charter or
     by-laws or pursuant to written agreements with any such Person, (B) make
     payments in respect of its other operational expenses (other than taxes)
     incurred in the ordinary course of business, or (C) make payments in
     respect of indemnification obligations and costs and expenses incurred by
     Holdings in connection with any offering of common stock of Holdings;
     provided, however, that all such payments will be included in the
     calculation of the amount of Restricted Payments.
 
     Limitation on Restrictions on Distributions from Restricted
Subsidiaries.  The Company will not, and will not permit any Restricted
Subsidiary to, create or otherwise cause or permit to exist or become effective
any consensual encumbrance or restriction on the ability of any Restricted
Subsidiary to (i) pay dividends or make any other distributions on its Capital
Stock or pay any Indebtedness owed to the Company, (ii) make any loans or
advances to the Company or (iii) transfer any of its property or assets to the
Company, except:
 
          (1) any encumbrance or restriction pursuant to an agreement in effect
     at or entered into on the Issue Date;
 
          (2) any encumbrance or restriction with respect to a Restricted
     Subsidiary pursuant to an agreement relating to any Indebtedness entered
     into prior to the date on which such Restricted Subsidiary was acquired or
     designated as a Restricted Subsidiary by the Company (other than as
     consideration in, in contemplation of, or to provide all or any portion of
     the funds or credit support utilized to consummate, the transaction or
     series of related transactions pursuant to which such Restricted Subsidiary
     became a Restricted Subsidiary or was otherwise acquired by the Company);
 
          (3) any encumbrance or restriction pursuant to (x) an agreement
     constituting Refinancing Indebtedness of Indebtedness Incurred pursuant to
     an agreement referred to in clause (1) or
 
                                       70

     agreement referred to in clause (1) or (2) of this covenant or this clause
     (3) or (y) Indebtedness Incurred pursuant to clause (i) or (ii) of
     paragraph (b) of the covenant described above under "-- Limitation on
     Indebtedness;" provided, however, that the encumbrances and restrictions
     contained in (A) any such refinancing agreement or amendment referred to in
     clause (x) above are, collectively, no more restrictive in any material
     respect than the encumbrances and restrictions contained in such agreements
     (as determined in good faith by the Company) and (B) any instrument
     relating to any Indebtedness referred to in clause (y) above, are,
     collectively, no more restrictive in any material respect than the
     encumbrances and restrictions contained in the Senior Bank Facilities as in
     effect on the Issue Date (as determined in good faith by the Company);
 
          (4) in the case of clause (iii) above, any encumbrance or restriction
     contained in security agreements or mortgages securing Indebtedness of a
     Restricted Subsidiary which are not prohibited by the covenant described
     under "-- Limitation on Liens" to the extent such encumbrances or
     restrictions restrict the transfer of the property or assets subject to
     such security agreements or mortgages;
 
          (5) any encumbrance or restriction existing under or by reason of
     applicable law;
 
          (6) customary non-assignment provisions of any licensing agreement or

          (8) with respect to a Restricted Subsidiary, any encumbrance or

          (9) Purchase Money Obligations for property acquired in the ordinary
     course of business that impose restrictions of the type referred to in
     clause (iii) of this covenant.
 
     Limitation on Sales of Assets and Subsidiary Stock.  (a) The Company will
not, and will not permit any Restricted Subsidiary to, make any Asset
Disposition unless:
 
          (i) the Company or such Restricted Subsidiary receives consideration
     (including by way of relief from, or by any other Person assuming sole
     responsibility for, any liabilities, contingent or otherwise) at the time
     of such Asset Disposition at least equal to the fair market value, as may
     be determined (and shall be determined, to the extent an Asset Disposition
     (or a series of related Asset Dispositions) involves a fair market value
     greater than $1.0 million) in good faith by the Board of Directors, whose
     determination will be conclusive and evidenced by a resolution of the Board
     of Directors (including as to the value of all non-cash consideration), of
     the shares and assets subject to such Asset Disposition;
 
          (ii) in the case of an Asset Disposition (or a series of related Asset
     Dispositions) having a fair market value of $1.0 million or more, at least
     80% (or 100% in the case of lease payments) of the consideration thereof
     received by the Company or such Restricted Subsidiary is in the form of
     cash or cash equivalents; and
 
          (iii) an amount equal to 100% of the Net Available Cash from such
     Asset Disposition is applied by the Company (or such Restricted Subsidiary,
     as the case may be) (A) first, to the extent the Company or such Restricted
     Subsidiary elects (or is required by the terms of any Senior Indebtedness),
     to prepay, repay or purchase Senior Indebtedness of the Company or a Wholly
     Owned Subsidiary or, in the case of a sale by a Restricted Subsidiary which
     is not a Wholly Owned Subsidiary, to prepay, repay or purchase Senior
     Indebtedness of such Restricted Subsidiary (in each case other than
     Indebtedness owed to the Company or an Affiliate of the Company) within 365
     days after the later of the date of such Asset Disposition or the receipt
     of such Net Available Cash; (B) second, to the extent of the balance of Net
     Available Cash after
 
                                       71
   75
 
     application in accordance with clause (A), to the extent the Company or
     such Restricted Subsidiary elects, to reinvest (or enter into a binding
     contract to do so) in Additional Assets (including by means of an
     Investment in Additional Assets by a Restricted Subsidiary with Net
     Available Cash received by the Company or another Restricted Subsidiary),
     within 365 days from the later of such Asset Disposition or the receipt of
     such Net Available Cash; (C) third, to the extent of the balance of such
     Net Available Cash after application in accordance with clauses (A) and
     (B), to make an Offer (as defined below) to purchase Notes pursuant to and
     subject to the conditions set forth in section (b) of this covenant and (D)
     fourth, to the extent of the balance of such Net Available Cash after
     application in accordance with clauses (A), (B) and (C), to fund (to the
     extent consistent with any other applicable provision of the Indenture) any
     corporate purpose; provided, however, that in connection with any
     prepayment, repayment or purchase of Indebtedness pursuant to clause (A)
     above, the Company or such Restricted Subsidiary will retire such
     Indebtedness and will cause the related loan commitment (if any) to be
     permanently reduced in an amount equal to the principal amount so prepaid,
     repaid or purchased. Notwithstanding the foregoing provisions of this
     covenant, the Company and its Restricted Subsidiaries will not be required
     to apply any Net Available Cash in accordance with this covenant except to
     the extent that the aggregate Net Available Cash from all Asset
     Dispositions in any year which are not applied in accordance with this
     covenant exceed $5.0 million in such year.
 
     For the purposes of clause (ii) of this covenant, the following are deemed
to be cash: (w) the assumption of Indebtedness of the Company (other than
Disqualified Stock of the Company) or any Restricted Subsidiary and the release
of the Company or such Restricted Subsidiary from all liability on such
Indebtedness in connection with such Asset Disposition, (x) securities received
by the Company or any Restricted Subsidiary from the transferee that are
promptly converted by the Company or such Restricted Subsidiary into cash, (y)
Indebtedness of any Restricted Subsidiary that is no longer a Restricted
Subsidiary as a result of such Asset Disposition, to the extent that the Company
and each other Restricted Subsidiary is released from any Guarantee of such
Indebtedness in connection with such Asset Disposition, and (z) consideration
consisting of Indebtedness of the Company or any Restricted Subsidiary.
 
     (b) In the event of an Asset Disposition that requires the purchase of
Notes pursuant to clause (a)(iii)(C) of this covenant, the Company will be
required to purchase Notes tendered pursuant to an offer, commenced within 30
days following the expiration of the 365 day period referred to in clause
(a)(iii)(B) of this covenant (or, if the Company so elects, at any time within
such 365 day period), by the Company for the Notes (the "Offer") at a purchase
price of 100% of their principal amount plus accrued and unpaid interest, if
any, to the date of purchase in accordance with the procedures (including
prorationing in the event of oversubscription) set forth in the Indenture. If
the aggregate purchase price of Notes tendered pursuant to the Offer is less
than the Net Available Cash allotted to the purchase of the Notes, the Company
will apply the remaining Net Available Cash in accordance with clause
(a)(iii)(D) of this covenant and upon completion of the purchase of the Notes
tendered pursuant to the Offer, the remaining amount of Net Available Cash, if
any, will be reset at zero. The Company will not be required to make an Offer
for Notes pursuant to this covenant if the Net Available Cash available therefor
(after application of the proceeds as provided in clauses (A) and (B) of section
(a)(iii) of this covenant) is less than $5.0 million (which lesser amount will
be carried forward for purposes of determining whether an Offer is required with
respect to the Net Available Cash from any subsequent Asset Disposition).
 
     (c) The Company will comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the repurchase of Notes pursuant to this
covenant. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this covenant, the Company will comply
with the applicable securities laws and regulations and will not be deemed to
have breached its obligations under this covenant by virtue thereof.
 
                                       72
   76
 
     Limitation on Transactions with Affiliates.  (a) The Company will not, and
will not permit any Restricted Subsidiary to, directly or indirectly, enter into
or conduct any transaction (including the purchase, sale, lease or exchange of
any property or the rendering of any service) with any Affiliate of the Company
(an "Affiliate Transaction") on terms (i) that are less favorable to the Company
or such Restricted Subsidiary, as the case may be, than those that could be
obtained at the time of such transaction in arm's-length dealings with a Person
who is not such an Affiliate and (ii) that , in the event such Affiliate
Transaction involves an aggregate amount in excess of $1.0 million, are not in
writing and have not been approved by a majority of the members of the Board of
Directors having no material direct or indirect financial interest in or with
respect to such Affiliate Transaction. In addition, if such Affiliate
Transaction involves an amount in excess of $5.0 million, a fairness opinion
must be obtained from a nationally recognized appraisal or investment banking
firm.
 
     (b) The provisions of the foregoing paragraph (a) will not prohibit (i) any
Restricted Payment or Permitted Investment permitted to be made pursuant to the
covenant described under "-- Limitation on Restricted Payments," (ii) fees,
compensation or employee benefit arrangements paid to, and any indemnity
provided for the benefit of, directors, officers or employees of the Company,
Holdings or any Subsidiary of the Company in the ordinary course of business or
any Indebtedness permitted to be Incurred pursuant to clause (xiii) of paragraph
(b) of the covenant described under "-- Limitation on Indebtedness," or any
payments in respect thereof, (iii) any issuance of securities, or other
payments, awards or grants in cash, securities or otherwise pursuant to, or the
funding of, employment arrangements, stock options and stock ownership plans
approved by the Board of Directors, (iv) transactions pursuant to agreements
entered into or in effect on the Issue Date, including amendments thereto
entered into after the Issue Date, provided that the terms of any such amendment
are not, in the aggregate, less favorable to the Company or such Restricted

or advances to employees that are Affiliates of the Company in the ordinary
course of business, but in any event not to exceed $2.0 million in the aggregate
outstanding at any one time, (vi) any transaction between the Company and a
Restricted Subsidiary or between Restricted Subsidiaries (so long as the other

Owned Subsidiaries are not themselves Affiliates of the Company) or (vii)
payments with respect to Indebtedness Incurred pursuant to clause (ix) of
paragraph (b) of the covenant described under "-- Limitation on Indebtedness."
 
     Limitation on the Sale or Issuance of Capital Stock of Restricted
Subsidiaries.  The Company will not sell any shares of Capital Stock of a
Restricted Subsidiary, and will not permit any Restricted Subsidiary, directly
or indirectly, to issue or sell any shares of its Capital Stock, except (i) to
the Company or a Wholly Owned Subsidiary, (ii) if, immediately after giving
effect to such issuance or sale, such Restricted Subsidiary would no longer
constitute a Restricted Subsidiary, (iii) directors' qualifying shares or (iv)
in a Public Equity Offering as a result of or after which a Public Market
exists. The proceeds of any sale of such Capital Stock permitted by clause (ii)
must be treated as Net Available Cash from an Asset Disposition and must be
applied in accordance with the terms of the covenant described under
"-- Limitation on Sales of Assets and Subsidiary Stock."
 
     Limitation on Liens.  (a) The Company will not, and will not permit any
Guarantor Subsidiary to, directly or indirectly, create or permit to exist any
Lien (the "Initial Lien") on any of its property or assets (including Capital
Stock), whether owned on the Issue Date or thereafter acquired, securing any
Indebtedness other than Senior Indebtedness of the Company, in the case of the
Company, or Senior Indebtedness of a Guarantor Subsidiary, in the case of a
Guarantor Subsidiary, unless contemporaneously therewith effective provision is
made to secure the Notes and, in respect of Liens on any Guarantor Subsidiary's
property or assets, the Subsidiary Guaranty of such Guarantor Subsidiary equally
and ratably with (or on a senior basis to, in the case of Indebtedness expressly
subordinated in right of payment to the Notes and such Subsidiary Guaranty) such
obligation for so long as such obligation is so secured. The preceding sentence
will not require the
 
                                       73
   77
 
Company or any Restricted Subsidiary to equally and ratably secure the Notes if
the Initial Lien consists of Permitted Liens.
 
     (b) Any Lien created for the benefit of the Holders of the Notes pursuant
to the foregoing paragraph (a) shall provide by its terms that such Lien shall
be automatically and unconditionally released and discharged upon the release
and discharge of the Initial Lien.
 
     SEC Reports.  Notwithstanding that the Company may not be required to be or
remain subject to the reporting requirements of Section 13 or 15(d) of the
Exchange Act, the Company will file with the Commission (after the date the
Exchange Offer or Shelf Registration Statement described under "-- Exchange and
Registration Rights Agreement" below becomes effective), and provide (both prior
to and after such effective date) the Trustee and Noteholders and prospective
Noteholders (upon request) with the annual reports and the information,
documents and other reports which are specified in Sections 13 and 15(d) of the
Exchange Act. The Company also will comply with the other provisions of TIA Sec.
314(a).
 
     Future Guarantor Subsidiaries.  The Company will cause (a) each Restricted
Subsidiary that is a Domestic Subsidiary which Incurs Indebtedness and (b) each
Restricted Subsidiary that is not a Domestic Subsidiary and that after the Issue
Date enters into a Guarantee of any of the obligations of the Company, Holdings
or any of the Company's Subsidiaries pursuant to the Senior Bank Facilities to
execute and deliver to the Trustee a supplemental indenture pursuant to which
such Subsidiary will Guarantee payment of the Notes; provided, however, that
such Subsidiary shall not be required to execute and deliver a supplemental
indenture pursuant to this section in the event that such Subsidiary is a party
to the Indenture or the Supplemental Indenture at the time of such Incurrence of
Indebtedness. Each Subsidiary Guaranty will be limited to an amount not to
exceed the maximum amount that can be Guaranteed by that Subsidiary without
rendering the Subsidiary Guaranty, as it relates to such Subsidiary, voidable
under applicable law relating to fraudulent conveyance or fraudulent transfer or
similar laws affecting the rights of creditors generally.
 
     Limitation on Lines of Business.  The Company will not, and will not permit
any Restricted Subsidiary to, engage in any business other than (i) a Related
Business and (ii) the making of Permitted Investments and the operations of any
business that is part of a Permitted Investment. Holdings will not engage in any
business other than managing its investment in the Company.
 
     Limitation on Sale/Leaseback Transactions.  The Company will not, and will
not permit any Restricted Subsidiary to, enter into any Sale/Leaseback
Transaction with respect to any property unless (i) the Company or such

pursuant to the covenant described under "-- Limitation on Indebtedness" and
(ii) the net cash proceeds received by the Company or any Restricted Subsidiary
in connection with such Sale/Leaseback Transaction are at least equal to the
fair market value (in the case of Sale/Leaseback Transactions involving amounts
in excess of $1.0 million, as determined by the Board of Directors, whose
determination will be conclusive and evidenced by a resolution of the Board of
Directors) of such property and (iii) the transfer of such property is permitted
by, and the Company applies the proceeds of such transaction in compliance with,
the covenant described under "-- Limitation on Sale of Assets and Subsidiary
Stock."
 
MERGER AND CONSOLIDATION
 
     The Company will not consolidate with or merge with or into, or convey,
transfer or lease all or substantially all its assets to, any Person, unless:
(i) the resulting, surviving or transferee Person (the "Successor Company") will
be a corporation, limited liability company, limited partnership or business
trust organized and existing under the laws of the United States of America, any
State thereof or the District of Columbia and the Successor Company (if not the
Company) will expressly assume, by an indenture supplemental hereto, executed
and delivered to the Trustee, in form satisfactory to the Trustee, all the
obligations of the Company under the Notes and the Indenture;
 
                                       74
   78
 
(ii) immediately after giving effect to such transaction (and treating any
Indebtedness which becomes an obligation of the Successor Company or any
Restricted Subsidiary as a result of such transaction as having been Incurred by
the Successor Company or such Restricted Subsidiary at the time of such
transaction), no Default will have occurred and be continuing; (iii) except in
the case of a merger the sole purpose of which is to change the Company's
jurisdiction of incorporation, immediately after giving effect to such
transaction, the Successor Company would be able to Incur an additional $1.00 of
Indebtedness under paragraph (a) of the covenant described under "-- Limitation
on Indebtedness"; (iv) immediately after giving effect to such transaction, the
Successor Company will have Consolidated Net Worth in an amount which is not
less than the Consolidated Net Worth of the Company immediately prior to such
transaction and (v) the Company will have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that such consolidation,
merger or transfer and such supplemental indenture (if any) comply with the
Indenture.
 
     Notwithstanding the foregoing clauses (ii), (iii) and (iv), any Restricted
Subsidiary may consolidate with, merge into or transfer all or part of its
properties and assets to the Company.
 
     The Successor Company will succeed to, and be substituted for, and may
exercise every right and power of, the Company under the Indenture, but the
predecessor Company in the case of a conveyance, transfer or lease of all or
substantially all its assets will not be released from the obligation to pay the
principal of and interest on the Notes.
 
DEFAULTS
 
     An Event of Default is defined in the Indenture as:
 
          (i) a default in any payment of interest on any Note when due (whether
     or not such payment is prohibited by the provisions described under
     "Ranking" above), continued for 30 days;
 
          (ii) a default in the payment of principal of any Note when due at its
     Stated Maturity, upon optional redemption, upon required repurchase, upon
     declaration or otherwise (whether or not such payment is prohibited by the
     provisions described under "Ranking" above);
 
          (iii) the failure by the Company to comply with its obligations under
     the covenant described under "Merger and Consolidation" above;
 
          (iv) the failure by the Company to comply for 30 days after notice
     with any of its obligations under the covenants described under "Change of
     Control" or "Certain Covenants" above (in each case, other than a failure
     to purchase Notes);
 
          (v) the failure by the Company or any Guarantor Subsidiary to comply
     for 60 days after notice with its other agreements contained in the Notes
     or the Indenture;
 
          (vi) the failure by the Company or any Significant Subsidiary to pay
     any Indebtedness within any applicable grace period after final maturity or
     the acceleration of any such Indebtedness by the holders thereof because of
     a default, if the total amount of such Indebtedness unpaid or accelerated
     exceeds $5.0 million or its foreign currency equivalent (the "cross
     acceleration provision");
 
          (vii) certain events of bankruptcy, insolvency or reorganization of
     the Company or a Restricted Subsidiary (the "bankruptcy provisions");
 
          (viii) the rendering of any judgment or decree in excess of $5.0
     million or its foreign currency equivalent (net of amounts paid within 30
     days of any such judgment or decree under any insurance, indemnity, bond,
     surety or similar instrument) against the Company or a Restricted
     Subsidiary by a court or other adjudicatory authority of competent
     jurisdiction for which the Company or the Restricted Subsidiary, as
     applicable, is not fully insured by a third
 
                                       75
   79
 
     Person and (A) an enforcement proceeding is commenced with respect to such
     judgment or decree or (B) such judgment or decree remains outstanding the
     later of (i) the day which is the sixtieth day after the judgment is
     rendered and (ii) the day on which any right to appeal expires (the
     "judgment default provision"); or
 
          (ix) any Subsidiary Guaranty ceases to be in full force and effect
     (except as contemplated by the terms thereof) or any Guarantor Subsidiary
     denies or disaffirms its obligations under the Indenture or any Subsidiary
     Guaranty and such Default continues for 10 days.
 
     The foregoing will constitute Events of Default whatever the reason for any
such Event of Default and whether it is voluntary or involuntary or is effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body.
 
     However, a default under clauses (iv) or (v) will not constitute an Event
of Default until the Trustee or the Holders of 25% in principal amount of the
outstanding Notes notify the Company of the default and the Company does not
cure such default within the time specified in clauses (iv) and (v) hereof after
receipt of such notice.
 
     If an Event of Default occurs and is continuing, the Trustee or the Holders
of at least 25% in principal amount of the outstanding Notes by notice to the
Company may declare the principal of and accrued but unpaid interest on all the
Notes to be due and payable. Upon such a declaration, such principal and
interest will be due and payable immediately. If an Event of Default relating to
certain events of bankruptcy, insolvency or reorganization of the Company occurs
and is continuing, the principal of and interest on all the Notes will become
immediately due and payable without any declaration or other act on the part of
the Trustee or any Holders. Under certain circumstances, the Holders of a
majority in principal amount of the outstanding Notes may rescind any such
acceleration with respect to the Notes and its consequences.
 
     Subject to the provisions of the Indenture relating to the duties of the
Trustee, in case an Event of Default occurs and is continuing, the Trustee will
be under no obligation to exercise any of the rights or powers under the
Indenture at the request or direction of any of the Holders unless such Holders
have offered to the Trustee reasonable indemnity or security against any loss,
liability or expense. Except to enforce the right to receive payment of
principal, premium (if any) or interest when due, no Holder may pursue any
remedy with respect to the Indenture or the Notes unless (i) such Holder has
previously given the Trustee notice that an Event of Default is continuing, (ii)
Holders of at least 25% in principal amount of the outstanding Notes have
requested the Trustee to pursue the remedy, (iii) such Holders have offered the
Trustee reasonable security or indemnity against any loss, liability or expense,
(iv) the Trustee has not complied with such request within 60 days after the
receipt of the request and the offer of security or indemnity and (v) the
Holders of a majority in principal amount of the outstanding Notes have not
given the Trustee a direction inconsistent with such request within such 60-day
period. Subject to certain restrictions, the Holders of a majority in principal
amount of the outstanding Notes are given the right to direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee
or of exercising any trust or power conferred on the Trustee. The Trustee,
however, may refuse to follow any direction that conflicts with law or the
Indenture or that the Trustee determines is unduly prejudicial to the rights of
any other Holder or that would involve the Trustee in personal liability. Prior
to taking any action under the Indenture, the Trustee will be entitled to
indemnification satisfactory to it in its sole discretion against all losses and
expenses caused by taking or not taking such action.
 
     The Indenture provides that if a Default occurs and is continuing and is
known to the Trustee, the Trustee must mail to each Holder notice of the Default
within the earlier of 90 days after it occurs or 30 days after it is known to a
Trust Officer or written notice of it is received by the Trustee. Except in the
case of a Default in the payment of principal of, premium (if any) or interest
on any Note, the Trustee may withhold notice if and so long as a committee of
its Trust Officers in good faith
 
                                       76
   80
 
determines that withholding notice is in the interests of the Noteholders. In
addition, the Company is required to deliver to the Trustee, within 120 days
after the end of each fiscal year, a certificate indicating whether the signers
thereof know of any Default that occurred during the previous year. The Company
also is required to deliver to the Trustee, within 30 days after the occurrence
thereof, written notice of any event which would constitute certain Defaults,
their status and what action the Company is taking or proposes to take in
respect thereof.
 
AMENDMENTS AND WAIVERS
 
     Subject to certain exceptions, the Indenture may be amended with the
consent of the Holders of a majority in principal amount of the Notes then
outstanding and any past default and its consequences or compliance with any
provisions may be waived with the consent of the Holders of a majority in
principal amount of the Notes then outstanding. However, without the consent of
each Holder of an outstanding Note affected, no amendment may (i) reduce the
amount of Notes whose Holders must consent to an amendment or waiver, (ii)
reduce the rate of or extend the time for payment of interest on any Note, (iii)
reduce the principal of or extend the Stated Maturity of any Note, (iv) reduce
the premium payable upon the redemption of any Note or change the time at which
any Note may be redeemed as described under "Optional Redemption" above, (v)
make any Note payable in money other than that stated in the Note, (vi) impair
the right of any Holder to receive payment of principal of and interest on such
Holder's Notes on or after the due dates therefor or to institute suit for the
enforcement of any payment on or with respect to such Holder's Notes, (vii) make
any change in the amendment provisions which require each Holder's consent or in
the waiver provisions or (viii) make any change in any Subsidiary Guaranty that
would adversely affect the Noteholders.
 
     Without the consent of any Holder, the Company and Trustee may amend the
Indenture to cure any ambiguity, omission, defect or inconsistency, to provide
for the assumption by a successor corporation of the obligations of the Company
under the Indenture, to provide for uncertificated Notes in addition to or in
place of certificated Notes (provided that the uncertificated Notes are issued
in registered form for purposes of Section 163(f) of the Code, or in a manner
such that the uncertificated Notes are described in Section 163(f)(2)(B) of the
Code), to add further Guaranties with respect to the Notes, to release Guarantor
Subsidiaries when permitted by the Indenture, to secure the Notes, to add to the
covenants of the Company for the benefit of the Noteholders or to surrender any
right or power conferred upon the Company, to make any change that does not
adversely affect the rights of any Holder or to comply with any requirement of
the Commission in connection with the qualification of the Indenture under the
TIA.
 
     The consent of the Noteholders is not necessary under the Indenture to
approve the particular form of any proposed amendment. It is sufficient if such
consent approves the substance of the proposed amendment.
 
     After an amendment under the Indenture becomes effective, the Company is
required to mail to Noteholders a notice briefly describing such amendment.
However, the failure to give such notice to all Noteholders, or any defect
therein, will not impair or affect the validity of the amendment.
 
TRANSFER AND EXCHANGE
 
     A Noteholder may transfer or exchange Notes in accordance with the
Indenture. Upon any transfer or exchange, the registrar and the Trustee may
require a Noteholder, among other things, to furnish appropriate endorsements
and transfer documents and the Company may require a Noteholder to pay any taxes
required by law or permitted by the Indenture. The Company is not required to
transfer or exchange any Note selected for redemption or to transfer or exchange
any Note for a period of 15 days prior to a selection of Notes to be redeemed.
The Notes will be issued in registered form and the registered holder of a Note
will be treated as the owner of such Note for all purposes.
 
                                       77
   81
 
DEFEASANCE
 
     The Company at any time may terminate all its obligations under the Notes
and the Indenture ("legal defeasance"), except for certain obligations,
including those respecting the defeasance trust and obligations to register the
transfer or exchange of the Notes, to replace mutilated, destroyed, lost or
stolen Notes and to maintain a registrar and paying agent in respect of the
Notes. The Company at any time may terminate its obligations under the covenants
described under "Certain Covenants," the operation of the cross acceleration
provision, the bankruptcy default provisions with respect to Subsidiaries and
the judgment default provision described under "Defaults" above and the
limitations contained in clauses (iii) and (iv) under "Merger and Consolidation"
above ("covenant defeasance"). If the Company exercises its legal defeasance
option or its covenant defeasance option, each Guarantor Subsidiary will be
released from all of its obligations with respect to its Subsidiary Guaranty.
 
     The Company may exercise its legal defeasance option notwithstanding its
prior exercise of its covenant defeasance option. If the Company exercises its
legal defeasance option, payment of the Notes may not be accelerated because of
an Event of Default with respect thereto. If the Company exercises its covenant
defeasance option, payment of the Notes may not be accelerated because of an
Event of Default specified in clause (iv), (vi), (vii) (with respect to
Restricted Subsidiaries only), (viii) (with respect to Significant Subsidiaries
only), (ix) or (x) under "Defaults" above or because of the failure of the
Company to comply with clause (iii) or (iv) under "Merger and Consolidation"
above.
 
     Defeasance options with respect to the Notes may be exercised to any
redemption date or the applicable maturity date. In order to exercise either
defeasance option, the Company must irrevocably deposit in trust (the
"defeasance trust") with the Trustee money or U.S. Government Obligations for
the payment of principal, premium (if any) and interest on the Notes to
redemption or maturity, as the case may be, and must comply with certain other
conditions, including delivery to the Trustee of an Opinion of Counsel to the
effect that holders of the Notes will not recognize income, gain or loss for
Federal income tax purposes as a result of such deposit and defeasance and will
be subject to Federal income tax on the same amount and in the same manner and
at the same times as would have been the case if such deposit and defeasance had
not occurred (and, in the case of legal defeasance only, such Opinion of Counsel
must be based on a ruling of the Internal Revenue Service or other change in
applicable Federal income tax law).

Indenture and has been appointed by the Company as Registrar and Paying Agent

EBITDA for such period shall be reduced by an amount equal to the EBITDA (if
positive) directly attributable to the assets which are the subject of such
Disposal for
 
                                       80
   84
 
such period or increased by an amount equal to the EBITDA (if negative) directly
attributable thereto for such period and (y) Consolidated Interest Expense for
such period shall be reduced by an amount equal to the Consolidated Interest
Expense directly attributable to any Indebtedness of the Company or any
Restricted Subsidiary repaid, repurchased, defeased or otherwise discharged with
respect to the Company and its continuing Restricted Subsidiaries in connection
with such Disposal for such period (or, if the Capital Stock of any Restricted
Subsidiary is sold, the Consolidated Interest Expense for such period directly
attributable to the Indebtedness of such Restricted Subsidiary to the extent the
Company and its continuing Restricted Subsidiaries are no longer liable for such
Indebtedness after such sale);

Subsidiary (by merger or otherwise) shall have made an Investment in any
Restricted Subsidiary (or any Person which becomes a Restricted Subsidiary) or
an acquisition of assets, including any acquisition of assets occurring in
connection with a transaction causing a calculation to be made hereunder, which
constitutes all or substantially all of the assets of an operating unit of a
business, EBITDA and Consolidated Interest Expense for such period shall be
calculated after giving pro forma effect thereto (including the Incurrence of
any Indebtedness in connection therewith) as if such Investment or acquisition
occurred on the first day of such period; and
 
     (4) if since the beginning of such period any Person (that subsequently

Disposal or any Investment or acquisition of assets that would have required an
adjustment pursuant to clause (2) or (3) above if made by the Company or a
Restricted Subsidiary during such period, EBITDA and Consolidated Interest
Expense for such period shall be calculated after giving pro forma effect
thereto as if such Disposal, Investment or acquisition of assets occurred on the
first day of such period.
 
     For purposes of this definition, whenever pro forma effect is to be given
to an acquisition of assets, the amount of income or earnings relating thereto
and the amount of Consolidated Interest Expense associated with any Indebtedness
Incurred in connection therewith, the pro forma calculations shall be determined
in good faith by a responsible financial or accounting Officer of the Company.
If any Indebtedness bears a floating rate of interest and is being given pro
forma effect, the interest expense on such Indebtedness shall be calculated as
if the rate in effect on the date of determination had been the applicable rate
for the entire period (taking into account any Interest Rate Agreement
applicable to such Indebtedness if such Interest Rate Agreement has a remaining
term as at the date of determination in excess of 12 months). If any
Indebtedness bears, at the option of the Company or a Restricted Subsidiary, a
fixed or floating rate of interest and is being given pro forma effect, then (i)
if any interest had accrued on such Indebtedness prior to the date of
determination, the interest expense on such Indebtedness shall be computed by
applying a fixed or floating rate of interest as selected by the Company or such
Restricted Subsidiary for the interest period immediately preceding such
determination or (ii) if no interest accrued on such Indebtedness prior to the
date of determination, the interest expense on such Indebtedness shall be
computed by applying, at the option of the Company or such Restricted
Subsidiary, either a fixed or floating rate. If any Indebtedness which is being
given pro forma effect was Incurred under a revolving credit facility that was
in effect throughout the applicable period, the interest expense on such
Indebtedness shall be computed based upon the average daily balance of such
Indebtedness during the applicable period.

Restricted Subsidiary as a dividend or other distribution (subject, in the case
of a dividend or other distribution to a Restricted Subsidiary, to the
limitations contained in clause (iii) below) and (B) the Company's equity in a
net loss of any such Person (other than an Unrestricted Subsidiary) for such
period shall be included in determining such Consolidated Net Income, (ii) for

indirectly, on the payment of dividends or the making of distributions by such
Restricted Subsidiary, directly or indirectly, to the Company, except that (A)
subject to the limitations contained in (iv) below, the Company's equity in the
net income of any such Restricted Subsidiary for such period shall be included
in such Consolidated Net Income up to the aggregate amount of cash that could
have been distributed by such Restricted Subsidiary during such period to the
Company or another Restricted Subsidiary as a dividend (subject, in the case of
a dividend that could have been made to another Restricted Subsidiary, to the
limitation contained in this clause) and (B) the Company's equity in a net loss
of any such Restricted Subsidiary for such period shall be included in

            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS
 
     In the opinion of Kirkland & Ellis, counsel to the Company, the following
are the material United States federal income tax consequences of the Exchange
Offer to a holder of Old Notes that is an individual citizen or resident of the
United States or a United States corporation that purchased the Old Notes
pursuant to their original issue (a "U.S. Holder"). The following discussion is
based on the Internal Revenue Code of 1986, as amended to the date hereof (the
"Code"), existing and proposed Treasury regulations, and judicial and
administrative determinations, all of which are subject to change at any time,
possibly on a retroactive basis. The following relates only to the Old Notes,
and the New Notes received therefor, that are held as "capital assets" within
the meaning of Section 1221 of the Code by U.S. Holders. It does not discuss
state, local or foreign tax consequences, nor does it discuss tax consequences
to categories of holders that are subject to special rules, such as foreign
persons, tax-exempt organizations, insurance companies, banks and dealers in
stocks and securities. Tax consequences may vary depending on the particular
status of an investor. No rulings will be sought from the Internal Revenue
Service with respect to the federal income tax consequences of the Exchange
Offer.
 
     PROSPECTIVE PURCHASERS OF THE NOTES ARE URGED TO CONSULT THEIR TAX ADVISORS
CONCERNING THE UNITED STATES FEDERAL INCOME TAX CONSEQUENCES TO THEM OF
ACQUIRING, OWNING AND DISPOSING OF THE NOTES, AS WELL AS THE APPLICATION OF
STATE, LOCAL AND FOREIGN INCOME AND OTHER TAX LAWS.
 
DEBT CHARACTERIZATION AND INTEREST INCOME
 
     The Company and each Holder will agree to treat the Notes as indebtedness
for federal income tax purposes, and the following discussion assumes that such
treatment is correct. If the Notes were not respected as debt, they likely would
be treated as equity ownership interests in the Company. In such event, the
Company would not be entitled to claim a deduction for interest payable on the
Notes. As a result, the Company's after-tax cash flow and, consequently, its
ability to make payments with respect to the Notes could be reduced.
 
     A Holder will recognize ordinary income when it receives or accrues
interest on the Notes in accordance with such Holder's method of tax accounting.
A Holder may be entitled to treat interest income on the Notes as "investment
income" for purposes of computing certain limitations concerning the
deductibility of investment interest expense.
 
     The Notes are not expected to be issued with "original issue discount"
within the meaning of Section 1273 of the Code ("OID"). A Holder who purchases a
Note after the initial distribution thereof at a discount that exceeds a
statutorily defined de minimis amount will be subject to the "market discount"
rules of the Code, and a Holder who purchases a Note at a premium will be
subject to the bond premium amortization rules of the Code.
 
DISPOSITION OF NOTES
 
     If a Holder sells a Note between interest payment dates, the Holder will
recognize gain or loss equal to the difference between the amount realized on
the sale and the Holder's adjusted tax basis in the Note. A Holder's adjusted
tax basis in a Note will be equal to the Holder's cost for the Note, (i)
increased by any interest that has accrued on the Note since the last interest
payment date, as well as any OID, market discount and gain previously included
by such Holder in income with respect to the Note, and (ii) decreased by any
bond premium previously amortized and any principal payments previously received
by such Holder with respect to such Note. Subject to the market discount rules,
any such gain or loss will be capital gain or loss, long- or short-term
depending upon whether the Holder has held the Note for more than one year.
Subject to certain limited exceptions, capital losses cannot be used to offset
ordinary income.
 
                                       93
   97
 
     A cash basis holder that sells a Note between interest payment dates will
be required to treat an amount equal to accrued but unpaid interest through the
date of sale as ordinary interest income, and to add such amount to its basis in
the Note.
 
TAX CONSEQUENCES TO FOREIGN HOLDERS
 
     For purposes of this discussion, a "Foreign Holder" is any corporation,
individual, partnership, estate or trust that is, as to the United States, a
foreign corporation, a non-resident alien individual, a foreign partnership, or
a non-resident fiduciary or foreign estate or trust.
 
     A Foreign Holder generally will not be subject to United States federal
withholding tax on interest paid on the Notes so long as the Foreign Holder (i)
is not actually or constructively a "10 percent shareholder" of the Company or a
"controlled foreign corporation" with respect to which the Company is a "related
person" within the meaning of the Code, and (ii) provides an appropriate
statement, signed under penalties of perjury, certifying that the beneficial
owner of the Note is a foreign person and providing that foreign person's name
and address. If the information provided in this statement changes, the foreign
person must so inform the Company within 30 days of such change. The statement
generally must be provided in the year a payment occurs or in either of the two
preceding years. If the foregoing conditions are not satisfied, then interest
paid on the Notes will be subject to United States withholding tax at a rate of
30 percent, unless such rate is reduced or eliminated pursuant to an applicable
tax treaty.
 
     Any capital gain a Foreign Holder realizes on the sale, redemption,
retirement or other taxable disposition of a Note will be exempt from United
States federal income and withholding tax, provided that (i) the gain is not
effectively connected with the Foreign Holder's conduct of a trade or business
in the United States, and (ii) in the case of a Foreign Holder that is an
individual, the Foreign Holder is not present in the United States for 183 days
or more in the taxable year.
 
     If the interest, gain or other income a Foreign Holder recognizes on a Note
is effectively connected with the Foreign Holder's conduct of a trade or
business in the United States, the Foreign Holder (although exempt from the
withholding tax previously discussed if an appropriate statement is furnished)
generally will be subject to United States federal income tax on the interest,
gain or other income at regular federal income tax rates. In addition, if the
Foreign Holder is a foreign corporation, it may be subject to a branch profits
tax equal to 30 percent of its "effectively connected earnings and profits," as
adjusted for certain items, unless it qualifies for a lower rate under an
applicable tax treaty.
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
     The Company will be required to report annually to the IRS, and to each
Holder of record, the amount of interest paid on the Notes (and the amount of
interest withheld for federal income taxes, if any) for each calender year,
except as to exempt Holders (generally, corporations, tax-exempt organizations,
qualified pension and profit-sharing trusts, individual retirement accounts, or
nonresident aliens who provide certification as to their status). Each Holder
(other than Holders who are not subject to the reporting requirements) will be
required to provide to the Company, under penalties of perjury, a certificate
containing the Holder's name, address, correct federal taxpayer identification
number and a statement that the Holder is not subject to backup withholding.
Should a nonexempt Holder fail to provide the required certificate, the Company
will be required to withhold 31% of the interest otherwise payable to the Holder
and to remit the withheld amount to the IRS as a credit against the Holder's
federal income tax liability.

                              PLAN OF DISTRIBUTION
 
     Each broker-dealer that receives New Notes for its own account pursuant to
the Exchange Offer must acknowledge that it will deliver a prospectus in
connection with any resale of such New Notes. This Prospectus, as it may be
amended or supplemented from time to time, may be used by a broker-dealer in
connection with resales of New Notes received in exchange for Old Notes where
such Old Notes were acquired as a result of market-making activities or other
trading activities. Each of the Company and the Guarantor Subsidiaries has
agreed that, for a period of 180 days after the Expiration Date, it will make
this Prospectus, as amended or supplemented, available to any broker-dealer to
use in connection with any such resale. In addition, until                , 1997

in the New Notes may be required to deliver a prospectus.
 
     Neither the Company nor the Guarantor Subsidiaries will receive any
proceeds from any sale of New Notes by broker-dealers. New Notes received by
broker-dealers for their own account pursuant to the Exchange Offer may be sold
from time to time in one or more transactions in the over-the-counter market, in
negotiated transactions, through the writing of options on the New Notes or a
combination of such methods of resale, at market prices prevailing at the time
of resale, at prices related to such prevailing market prices or negotiated
prices. Any such resale may be made directly to purchasers or to or through
brokers or dealers who may receive compensation in the form of commissions or
concessions from any such broker-dealer or the purchasers of any such New Notes.
Any broker-dealer that resells New Notes that were received by it for its own
account pursuant to the Exchange Offer and any broker or dealer that
participates in a distribution of such New Notes may be deemed to be an
"underwriter" within the meaning of the Securities Act and any profit on any
such resale of New Notes and any commissions or concessions received by any such
persons may be deemed to be underwriting compensation under the Securities Act.
The Letter of Transmittal states that, by acknowledging that it will deliver and
by delivering a prospectus, a broker-dealer will not be deemed to admit that it
is an "underwriter" within the meaning of the Securities Act.
 
     For a period of 180 days after the Expiration Date the Company will
promptly send additional copies of this Prospectus and any amendment or
supplement to this Prospectus to any broker-dealer that requests such documents
in the Letter of Transmittal. The Company and each of the Guarantor Subsidiaries
has jointly and severally agreed to pay all expenses incident to the Exchange
Offer (including the expenses of one counsel for the holders of the Old Notes)
other than commissions or concessions of any brokers or dealers and will
indemnify the holders of the Old Notes (including any broker-dealers) against
certain liabilities, including liabilities under the Securities Act.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
Board of Directors
  Neenah Corporation
 
     We have audited the accompanying consolidated balance sheets of Neenah
Corporation (the Company) as of March 31, 1996 and 1997, and the related
consolidated statements of income, changes in stockholders' equity and cash
flows for each of the three years in the period ended March 31, 1997. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
the Company as of March 31, 1996 and 1997, and the consolidated results of its
operations and its cash flows for each of the three years in the period ended
March 31, 1997, in conformity with generally accepted accounting principles.

1. NATURE OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES
 
NATURE OF OPERATIONS
 
     Neenah Corporation (the Company) operates in one business segment for
financial reporting purposes: the manufacture of gray and ductile iron castings.
The Company's principal operating subsidiary, Neenah Foundry Company (Foundry),
manufactures castings sold directly to industrial customers throughout the
United States, and to heavy municipal customers throughout the United States and
several foreign countries either directly or through representatives. Industrial
castings are custom-engineered and are produced for customers in several
industries, with a concentration in the medium and heavy-duty truck components,
farm equipment, and heating, ventilation, and air-conditioning industries. Heavy
municipal castings include manhole covers and frames, storm sewer frames and
grates, trench drain systems, tree grates and specialty castings for a variety
of applications.
 
     Industrial castings are generally sold to large, well-established
companies, with two customers accounting for 18% and 15% of net sales in fiscal
1995, 17% and 9% of net sales in fiscal 1996, and 16% and 10% of net sales in
fiscal 1997. Combined receivables from these two customers totaled $4,974 and
$6,651 at March 31, 1996 and 1997, respectively. Municipal castings are sold to
a large number of customers. The Company's accounts receivable generally are
unsecured.
 
     The Company's other operating subsidiaries include Neenah Transport, Inc.
(Transport) and Hartley Controls Corporation (Hartley). Transport is a common
and contract carrier licensed to operate in the continental United States. The
majority of Transport's revenues are derived from transport services provided to
Foundry. Hartley designs and manufactures customized sand control systems for
the foundry industry, which are sold and serviced throughout the United States
and several foreign countries. Hartley and Transport each account for less than
10% of the Company's net sales, net income and total assets.
 
PRINCIPLES OF CONSOLIDATION
 
     The consolidated financial statements include the accounts of the Company
and its wholly owned subsidiaries, Foundry, Transport and Hartley. All
significant intercompany accounts and transactions have been eliminated in
consolidation.
 
USE OF ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
CASH AND CASH EQUIVALENTS
 
     For purposes of the consolidated statement of cash flows, the Company
considers all highly liquid investments with a maturity of three months or less
when purchased to be cash equivalents. Cash equivalents, consisting principally
of investments in commercial paper, totaled $11,598 and $23,028 at March 31,
1996 and 1997, respectively. The cost of these debt securities, which are
considered as "available for sale" for financial reporting purposes,
approximates fair value at both March 31, 1996 and 1997. There were no realized
gains or losses recognized on these securities during any of the three years in
the period ended March 31, 1997.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
INVENTORIES
 
     Inventories are stated at the lower of cost or market. Cost is determined
on the last-in, first-out (LIFO) method for substantially all inventories except
for supplies, for which cost is determined on the first-in, first-out (FIFO)
method.
 
PROPERTY, PLANT AND EQUIPMENT
 
     Property, plant and equipment are recorded at cost. Expenditures for
additions and improvements are capitalized while replacements, maintenance and
repairs which do not improve or extend the lives of the respective assets are
expensed as incurred.
 
     Depreciation for financial reporting purposes is provided over the
estimated useful lives of the respective assets, using accelerated and
straight-line methods. Depreciation expense includes amortization of machinery
and equipment recorded under capitalized leases.
 
REVENUE RECOGNITION
 
     Revenue from the sale of castings and sand control systems is recognized
upon shipment to the customer.
 
ADVERTISING COSTS
 
     Advertising costs are expensed as incurred, and amounted to $467, $527 and
$524 for the years ended March 31, 1995, 1996 and 1997, respectively.
 
INCOME TAXES
 
     Deferred income taxes are provided for temporary differences between the
financial reporting and income tax basis of the Company's assets and liabilities
and are measured using currently enacted tax rates and laws.
 
FINANCIAL INSTRUMENTS
 
     The Company has a number of financial instruments, none of which are held
for trading purposes. The Company estimates that the fair value of all financial
instruments at March 31, 1996 and 1997 does not differ materially from the
carrying value of such instruments recorded in the accompanying consolidated
balance sheets, as follows:
 


                                                                          MARCH 31,

     The Company has a revolving credit agreement (the Agreement) with a bank
that provides for borrowings up to $25,000 through July 31, 1998. Interest is
payable monthly on outstanding borrowings at the bank's Reference Rate (8.25% at
March 31, 1997). The Agreement contains an option that allows the Company to
designate a portion (minimum of $2,000) of the borrowings to bear a fixed rate
of interest for a specified period of time. Borrowings under the Agreement are
unsecured and a quarterly fee is charged by the bank on the unused portion of
the facility.

Class B common stock from other shareholders, and are secured by such common
stock. These notes are scheduled to be repaid by the owners prior to the
consummation of the plan of reorganization described in Note 9.

     The Company is involved in a number of product liability claims, none of
which, in the opinion of management, is expected to have a material adverse
effect on the consolidated financial statements.
 
     The Company is partially self-insured for workers compensation claims. An
accrued liability is recorded for claims incurred but not yet paid or reported,
with such accrual based on current and historical claim information. The accrual
may ultimately be settled for an amount greater or lesser than the recorded
amount. Adjustments of the accrual are recorded in the period in which they are
determined.

aggregate amount of $595, which secure certain workers compensation and other
obligations.

7. EMPLOYEE BENEFIT PLANS
 
DEFINED BENEFIT PENSION PLANS
 
     The Company sponsors two defined benefit pension plans covering
substantially all hourly employees and previously sponsored a defined benefit
supplemental executive retirement plan (SERP) which covered certain salaried
employees. During the year ended March 31, 1997, the Company purchased
nonparticipating annuity contracts to settle the vested benefit obligations
under the SERP. Retirement benefits for the pension plans are based on years of
credited service and defined benefit rates while retirement benefits for the
SERP were based on compensation levels. The Company funds the pension plans
based on an actuarially determined cost method allowable under Internal Revenue
Service regulations. The SERP was unfunded.

     The weighted-average discount rate used in determining the accumulated
postretirement benefit obligations for both plans was 7.5% for all years, and
the healthcare cost trend rate was projected to have annual increases of 8.5%.
The healthcare cost trend rate assumption has a significant effect on the
amounts reported. Increasing the healthcare cost trend rate by one percentage
point would increase the accumulated postretirement benefit obligations as of
March 31, 1997 by $1,014 and would increase postretirement benefit expense for
the year ended March 31, 1997 by $131.

THE COMPANY
 
United States Trust Company of New York
114 West 47th Street
New York, N.Y. 10036
 
Ladies and Gentlemen:
 
     This certificate is delivered to request a transfer of $          principal
amount of the 11 1/8% Senior Subordinated Notes due 2007 (the "Notes") of Neenah
Corporation (the "Company").
 
     Upon transfer, the Notes would be registered in the name of the new
beneficial owner as follows:
 
        Name: ------------------------------------------------------------------
 
        Address:
               -----------------------------------------------------------------
 
        Taxpayer ID Number:-----------------------------------------------------
 
     The undersigned represents and warrants to you that:
 
     1. We are an institutional "accredited investor" (as defined in Rule
501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended (the
"Securities Act")) purchasing for our own account or for the account of such an
institutional "accredited investor" at least $250,000 principal amount of the
Notes, and we are acquiring the Notes not with a view to, or for offer or sale
in connection with, any distribution in violation of the Securities Act. We have
such knowledge and experience in financial and business matters as to be capable
of evaluating the merits and risk of our investment in the Notes and invest in
or purchase securities similar to the Notes in the normal course of our
business. We and any accounts for which we are acting are each able to bear the
economic risk of our or its investment.
 
     2. We understand that the Notes have not been registered under the
Securities Act and, unless so registered, may not be sold except as permitted in
the following sentence. We agree on our own behalf and on behalf of any investor
account for which we are purchasing Notes to offer, sell or otherwise transfer
such Notes prior to the date which is two years after the later of the date of
original issue and the last date on which the Company or any affiliate of the
Company was the owner of such Notes (or any predecessor thereto) (the "Resale
Restriction Termination Date") only (a) to the Company, (b) pursuant to a
registration statement which has been declared effective under the Securities
Act, (c) in a transaction complying with the requirements of Rule 144A under the
Securities Act, to a person we reasonably believe is a qualified institutional
buyer under Rule 144A (a "QIB") that purchases for its own account or for the
account of a QIB and to whom notice is given that the transfer is being made in
reliance on Rule 144A, (d) pursuant to offers and sales that occur outside the
United States within the meaning of Regulation S under the Securities Act, (e)
to an institutional "accredited investor" within the meaning of Rule 501(a)(1),
(2), (3) or (7) under the Securities Act that is purchasing for its own account
or for the account of such an institutional "accredited investor," in each case
in a minimum principal amount of Notes of $250,000 or (f) pursuant to any other
available exemption from the registration requirements of the Securities Act,
subject in each of the foregoing cases to any requirement of law that the
disposition of our property or the property of such investor account or accounts
be at all times within our or their control and in compliance with any
applicable state securities laws. The foregoing restrictions on resale will not
apply subsequent to the Resale Restriction Termination Date. If any resale or
other transfer of the Notes is proposed to be made pursuant to clause (e) above
prior to the Resale Restriction Termination Date, the transferor shall deliver a
letter from the transferee substantially in
 
                                       A-1
   115
 
the form of this letter to the Company and the Trustee, which shall provide,
among other things, that the transferee is an institutional "accredited
investor" within the meaning of Rule 501(a)(1), (2), (3) or (7) under the
Securities Act and that it is acquiring such Notes for investment purposes and
not for distribution in violation of the Securities Act. Each purchaser
acknowledges that the Company and the Trustee reserve the right prior to the
offer, sale or other transfer prior to the Resale Restriction Termination Date
of the Notes pursuant to clause (d), (e) or (f) above to require the delivery of
an opinion of counsel, certifications and/or other information satisfactory to
the Company and the Trustee.
 
                                          TRANSFEREE:

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Sections 180.0850 to 180.0859 of the Wisconsin Statutes require a
corporation to indemnify any director or officer who is a party to any
threatened, pending or completed civil, criminal, administrative or
investigative action, suit, arbitration or other proceeding, whether formal or
informal, which involves foreign, federal, state or local law and which is
brought by or in the right of the corporation or by any other person. A
corporation's obligation to indemnify any such person includes the obligation to
pay any judgment, settlement, penalty, assessment, forfeiture or fine, including
any excise tax assessed with respect to an employee benefit plan, and all
reasonable expenses including fees, costs, charges, disbursements, attorney's
and other expenses except in those cases in which liability was incurred as a
result of the breach or failure to perform a duty which the director or officer
owes to the corporation and the breach or failure to perform constitutes: (i) a
willful failure to deal fairly with the corporation or its shareholders in
connection with a matter in which the director or officer has a material
conflict of interest; (ii) a violation of criminal law, unless the person has
reasonable cause to believe his conduct was lawful or had no reasonable cause to
believe his conduct was unlawful; (iii) a transaction from which the person
derived an improper personal profit; or (iv) willful misconduct.
 
     Unless otherwise provided in a corporation's articles of incorporation or
by-laws or by written agreement, an officer or director seeking indemnification
is entitled to indemnification if approved in any of the following manners: (i)
by majority vote of a disinterested quorum of the board of directors, or if such
quorum of disinterested directors cannot be obtained, by a majority vote of a
committee or two or more disinterested directors; (ii) by independent legal
counsel; (iii) by a panel of three arbitrators; (iv) by affirmative vote of
shareholders; (v) by a court; or (vi) with respect to any additional right to
indemnification granted by any other method permitted in Section 180.0859 of the
Wisconsin Statutes.
 
     Reasonable expenses incurred by a director or officer who is a party to a
proceeding may be reimbursed by a corporation at such time as the director or
officer furnishes to the corporation written affirmation of his good faith
belief that he has not breached or failed to perform his duties and a written
undertaking to repay any amounts advanced if it is determined that
indemnification by the corporation is not required.
 
     The indemnification provisions of Sections 180.0850 to 180.0859 are not
exclusive. A corporation may expand an officer's or director's right to
indemnification (i) in its articles of incorporation or
 
                                      II-1
   118
 
by-laws; (ii) by written agreement, (iii) by resolution of its board of
directors; or (iv) by resolution of a majority of all of the corporation's
voting shares then issued and outstanding.
 
     As permitted by Section 180.0859, the Registrant has adopted
indemnification provisions in its By-Laws which closely track the statutory
indemnification provisions with certain exceptions. In particular, Article VIII
of the Registrant's By-Laws provides that payment or reimbursement of expenses,
subject to certain limitations, will be mandatory rather than permissive.
 
     The Registrant maintains and has in effect insurance policies covering all
of their respective directors and officers against certain liabilities for
actions taken in such capacities, including liabilities under the Securities Act
of 1933.

     (a) Exhibits.
 
     See Exhibit Index
 
     (b) Financial Statement Schedules.
 
ITEM 22.  UNDERTAKINGS.
 
     The undersigned registrant hereby undertakes:
 
          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement;
 
          (i) To include any prospectus required by Section 10(a)(3) of the
     Securities Act of 1933;
 
          (ii) To reflect in the prospectus any facts or events arising after
     the effective date of the registration statement (or the most recent
     post-effective amendment thereof) which individually or in the aggregate,
     represent a fundamental change in the information set forth in the
     registration statement;
 
          (iii) To include any material information with respect to the plan of
     distribution not previously disclosed in the registration statement or any
     material change to such information in the registration statement;
 
          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at the time shall be deemed to
     be the initial bona fide offering thereof;
 
          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering; and
 
          (4) The undersigned registrant hereby undertakes as follows: that
     prior to any public reoffering of the securities registered hereunder
     through use of a prospectus which is a part of this registration statement,
     by any person or party who is deemed to be an underwriter within the
     meaning of Rule 145(c), the issuer undertakes that such reoffering
     prospectus will contain the information called for by the applicable
     registration form with respect to reofferings by persons who may be deemed
     underwriters, in addition to the information called for by the other items
     of the applicable form.
 
          (5) The registrant undertakes that every prospectus: (i) that is filed
     pursuant to paragraph (1) immediately preceding, or (ii) that purports to
     meet the requirements of Section 10(a)(3) of the Act and is used in
     connection with an offering of securities subject to Rule 415, will be
     filed as a part of an amendment to the registration statement and will not
     be used until such amendment is effective, and that, for purposes of
     determining any liability under the Securities Act of 1933, each such
     post-effective amendment shall be deemed to be a new
 
                                      II-2
   119
 
     registration statement relating to the securities offered therein, and the
     offering of such securities at that time shall be deemed to be the initial
     bona fide offering thereof.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 (the "Securities Act") may be permitted to directors, officers and
controlling persons of the registrant pursuant to the provisions described under
Item 20 or otherwise, the registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Securities Act and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other than the
payment by the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.
 
     The undersigned registrant hereby undertakes that:
 
          (6) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of this registration statement in reliance upon Rule 430A and contained in
     a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     registration statement as of the time it was declared effective.
 
          (7) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     prospectus shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.
 
          (8) The undersigned registrant hereby undertakes to respond to
     requests for information that is incorporated by reference into the
     prospectus pursuant to Item 4, 10(b), 11 or 13 of this form, within one
     business day of receipt of such request, and to send the incorporated
     documents by first class mail or other equally prompt means. This includes
     information contained in documents filed subsequent to the effective date
     of the registration statement through the date of responding to the
     request.
 
          (9) The undersigned registrant hereby undertakes to supply by means of
     a post-effective amendment all information concerning a transaction, and
     the company being acquired involved therein, that was not the subject of
     and included in the registration statement when it became effective.
