                                  $125,000,000

                          WABASH NATIONAL CORPORATION
                         3.25% CONVERTIBLE SENIOR NOTES
                               DUE AUGUST 1, 2008
                                      AND
                        6,510,416 SHARES OF COMMON STOCK
                     ISSUABLE UPON CONVERSION OF THE NOTES

       Holders of our 3.25% Convertible Senior Notes due August 1, 2008 named
herein may offer for sale the notes and the shares of our common stock into
which the notes are convertible at any time at market prices prevailing at the
time of sale or at privately negotiated prices. The selling holders may sell the
notes or the common stock directly to purchasers or through underwriters,
broker-dealers or agents, who may receive compensation in the form of discounts,
concessions or commissions.

     The notes are convertible, at the option of the holder, into shares of our
common stock. The notes are convertible at a conversion price of $19.20 per
share, which is equal to a conversion rate of approximately 52.0833 shares of
common stock per $1,000 principal amount of notes, subject to adjustment.

     We will pay interest on the notes on August 1 and February 1 of each year,
beginning on February 1, 2004, and at maturity. The notes will mature on August
1, 2008.

     The notes are our unsecured and unsubordinated obligations and rank on a
parity (except as described below) in right of payment with all our existing and
future unsecured and unsubordinated indebtedness. In addition, the notes
effectively rank junior to any secured indebtedness we currently have and may
incur in the future to the extent of the value of the assets securing such debt
and effectively junior to our subsidiaries' liabilities.


     Our common stock currently trades on the New York Stock Exchange under the
symbol "WNC." The last reported sale price on August 16, 2004 was $26.64 per
share.


     INVESTING IN OUR COMMON STOCK OR THE NOTES INVOLVES A HIGH DEGREE OF RISK.
PLEASE CAREFULLY CONSIDER THE "RISK FACTORS" BEGINNING ON PAGE 4 OF THIS
PROSPECTUS.

     Neither the Securities and Exchange Commission nor any state securities
commission has approved or disapproved of these securities or passed upon the
adequacy or accuracy of this prospectus. Any representation to the contrary is a

OVERVIEW


     We are one of North America's leaders in designing, manufacturing and
marketing standard and customized truck trailers and related transportation
equipment. Founded in 1985 as a start-up, we grew to over $1.4 billion in sales
in 1999, and had over $888 million in sales in 2003. Our sales in the six-month
period ended June 30, 2004 were approximately $476 million. For the year ended
December 31, 2003, our net loss was approximately $57 million, and our net
income for the six-month period ended June 30, 2004 was approximately $25.1
million.


     We market our transportation equipment under the Wabash(R) and DuraPlate(R)
trademarks directly to customers, through independent dealers and through our
factory-owned retail branch network. Our proprietary DuraPlate(R) composite
truck trailer, which we introduced in 1996, has achieved widespread acceptance
by our customers. In 2003, sales of our DuraPlate(R) trailers represented
approximately 80% of our total trailers shipped. We are also a competitive
producer of standardized products, and are seeking to become a low-cost producer
within our industry.

STRATEGY

     We are committed to an operating strategy that seeks to deliver
profitability throughout industry cycles. We intend to achieve our goals by
executing on the core elements of our strategic plan:

     - continue our transition from an organization focused on revenue to one
       focused on earnings and cash flow;

     - continue to provide differentiated products that generate enhanced profit
       margins;

     - continue to reduce our cost structure by adhering to continuous
       improvement and lean manufacturing initiatives;

     - continue to focus on our longstanding customer partnerships and create
       new revenue opportunities by offering tailored transportation solutions;

     - divest non-core assets; and

     - delever the balance sheet to enhance financial flexibility and enable us
       to capitalize on future market opportunities.

                                  THE OFFERING

     The following is a brief summary description of this offering. For a more
complete description of the terms of the notes, see "Description of the Notes"
in this prospectus.

Issuer........................   Wabash National Corporation

                                        1


Selling Holders...............   All of the notes and common stock are being
                                 offered by selling holders named herein, and
                                 the Company will not receive any proceeds from
                                 the offering.

Securities Covered by this
Prospectus....................   $125,000,000 principal amount of 3.25%
                                 Convertible Senior Notes due August 1, 2008 and
                                 the shares of common stock issuable upon
                                 conversion of such notes.

Maturity......................   August 1, 2008

Interest......................   The notes bear interest at 3.25% per annum on
                                 the principal amount, payable semiannually in
                                 arrears on August 1, and February 1, beginning
                                 on February 1, 2004, and at maturity.

Conversion Rights.............   Holders may convert their notes prior to
                                 maturity, in multiples of $1,000 principal
                                 amount, into shares of our common stock at any
                                 time. Initially the notes were convertible only
                                 after the occurrence of certain events, but as
                                 of January 1, 2004 the conditions to conversion
                                 were met.

                                 For each $1,000 principal amount of notes
                                 surrendered for conversion, holders will
                                 receive 52.0833 shares of our common stock.
                                 This represents an initial conversion price of
                                 $19.20 per share of common stock. As described
                                 in this prospectus, the conversion rate may be
                                 adjusted for certain reasons, but it will not
                                 be adjusted for accrued and unpaid interest.

Ranking.......................   The notes are our senior unsecured and
                                 unsubordinated obligations and:

                                 - rank on a parity in right of payment with all
                                   existing and future senior unsecured and
                                   unsubordinated debt;

                                 - will rank senior to any future subordinated
                                   debt;

                                 - are effectively subordinated to any secured
                                   debt to the extent of the value of the assets
                                   securing such debt; and

                                 - are effectively subordinated to all
                                   liabilities and preferred stock of our
                                   subsidiaries.


                                 See "Description of the Notes -- Ranking." As
                                 of June 30, 2004, we had $85 million of secured
                                 indebtedness and $128 million of unsecured
                                 indebtedness.


Change of Control.............   Upon a change of control event (as defined in
                                 the indenture governing the notes), each holder
                                 of the notes may require us to repurchase some
                                 or all of its notes at a repurchase price equal
                                 to 100% of the aggregate principal amount of
                                 the notes plus accrued and unpaid interest. The
                                 repurchase price is payable:

                                 - in cash; or

                                 - in shares of our common stock, at our option,
                                   subject to the satisfaction of certain
                                   conditions as provided in the indenture. The
                                   number of shares of common stock will equal
                                   the repurchase price divided by 95% of the
                                   average of the closing sale prices of the
                                   common stock for the five consecutive trading
                                   days

                                        2


                                   ending on and including the third day prior
                                   to the repurchase date.

                                 Upon a change of control, certain of our
                                 existing debt agreements would, and any debt
                                 agreements we enter into in the future may,
                                 prohibit us from paying the repurchase price in
                                 cash unless prior to any such payment we either
                                 repay our outstanding indebtedness subject to
                                 such restrictions, refinance such debt on other
                                 terms or obtain a waiver from such lenders. As
                                 a result, we cannot assure you that we will be
                                 able to pay the repurchase price in cash.

                                 See "Description of the Notes -- Change of
                                 Control Permits Purchase of Notes at the Option
                                 of the Holder."

Use of Proceeds...............   We will not receive any of the proceeds of
                                 sales by the selling holders of any of the
                                 securities covered by this prospectus.

Form..........................   The notes have been issued in book-entry form
                                 and are represented by permanent global
                                 certificates deposited with, or on behalf of,
                                 The Depository Trust Company ("DTC") and
                                 registered in the name of a nominee of DTC.
                                 Beneficial interests in any of the notes are
                                 shown on, and transfers are effected only
                                 through, records maintained by DTC or its
                                 nominee, and any such interest may not be
                                 exchanged for certificated securities, except
                                 in limited circumstances.

Risk Factors..................   See "Risk Factors" and the other information
                                 included and incorporated by reference in this
                                 prospectus for a discussion of factors you
                                 should carefully consider before deciding to
                                 invest in the notes.

                                        3


                                  RISK FACTORS

     You should carefully consider the risks described below in addition to
other information contained or incorporated by reference in this prospectus
before making an investment decision. Realization of any of the following risks
could have a material adverse effect on our business, financial condition, cash
flows and results of operations.

RISKS RELATED TO OUR SUBSTANTIAL INDEBTEDNESS

 OUR SUBSTANTIAL INDEBTEDNESS COULD ADVERSELY AFFECT OUR FINANCIAL CONDITION.


     We are highly leveraged and have substantial debt in relation to our
shareholders' equity. As of June 30, 2004, we had an aggregate of $213 million
of outstanding indebtedness.


     Our high level of debt could have important consequences to our investors,
including:

     - we may not be able to secure additional funds for working capital,
       capital expenditures, debt service requirements or general corporate
       purposes;

     - we will need to use a portion of our cash flow from operations to pay
       principal of and interest on our debt, which will reduce the amount of
       funds available to us for other purposes;

     - we may be more highly leveraged than our competitors, which could put us
       at a competitive disadvantage; and

     - we may not be able to adjust rapidly to changing market conditions, which
       may make us more vulnerable in the event of a downturn in general
       economic conditions of our business.

 RESTRICTIVE COVENANTS IN OUR DEBT INSTRUMENTS COULD LIMIT OUR FINANCIAL AND
 OPERATING FLEXIBILITY AND SUBJECT US TO OTHER RISKS.

     The agreements governing our indebtedness include certain covenants that
restrict, among other things, our ability to:

     - incur additional debt;

     - pay dividends on our equity or repurchase our equity;

     - make certain investments;

     - create certain liens; and

     - consolidate, merge or transfer all or substantially all of our assets.

     Our ability to comply with such agreements may be affected by events beyond
our control, including prevailing economic, financial and industry conditions.
In addition, upon the occurrence of an event of default under our debt
agreements, the lenders could elect to declare all amounts outstanding under our
debt agreements, together with accrued interest, to be immediately due and
payable.

RISKS RELATED TO OUR BUSINESS, STRATEGY AND OPERATIONS

 WE HAVE NOT GENERATED PROFITABILITY IN RECENT PERIODS.


     The Company incurred significant net losses during the last three years.
While in the first six months of 2004, ended June 30, 2004, we reported net
income of $25.1 million, we have reported net losses of $232.2 million, $56.2
million and $57.2 million for the years ended December 31, 2001, 2002 and 2003,
respectively. The Company's ability to achieve and sustain profitability in the
future will depend on the successful implementation of measures to reduce costs
and achieve sales goals. While we have taken steps to improve cost performance,
lower operating costs and reduce interest expense, and have seen our sales
improve


                                        4


in the recent periods, we cannot assure you that our cost-reduction measures
will be successful, sales will be sustained or increased or that we can achieve
a sustained return to profitability.

 OUR INVENTORIES ARE NOT MANAGED BY PERPETUAL INVENTORY CONTROL SYSTEMS.

     Systems and processes used to manage and value our inventories require
significant manual intervention and the verification of actual quantities
requires a physical inventory which is taken once a year. Breakdowns of these
systems and processes, and errors in inventory estimates derived from these
systems and processes, could go undetected until the next physical inventory and
adversely affect our operations and financial results.

 AN ADVERSE CHANGE IN OUR CUSTOMER RELATIONSHIPS OR IN THE FINANCIAL CONDITION
 OF OUR CUSTOMERS COULD ADVERSELY AFFECT OUR BUSINESS.


     We have corporate partnering relationships with a number of customers where
we supply the requirements of these customers. We do not have binding agreements
with these customers. Our success is dependent, to a significant extent, upon
the continued strength of these relationships and the growth of our corporate
partners. We often are unable to predict the level of demand for our products
from these partners, or the timing of their orders. In addition, the same
economic conditions that adversely affect us also often adversely affect our
customers. As some of our customers are highly leveraged and have limited access
to capital, their continued existence may be uncertain. One of our customers,
Grupo Transportation Marititma Mexicana SA (TMM), located in Mexico has been
experiencing financial difficulties and on August 5, 2004, announced that it had
completed the restructuring of its existing debt agreements. Payments from TMM
to us, which have historically been timely, are currently behind schedule. The
customer owes us $7.8 million secured by highly specialized RoadRailer(R)
equipment, which due to the nature of the equipment, has a minimal recovery
value. The loss of a significant customer or unexpected delays in product
purchases could adversely affect our business and results of operations.


 OUR TECHNOLOGY AND PRODUCTS MAY NOT ACHIEVE MARKET ACCEPTANCE, WHICH COULD
 ADVERSELY AFFECT OUR COMPETITIVE POSITION.

     We continue to introduce new products such as the DuraPlate(R) HD, and the
Freight-Pro(R) trailer. We cannot assure you that these or other new products or
technologies will achieve sustained market acceptance. In addition, new
technologies or products that our competitors introduce may render our products
obsolete or uncompetitive. We have taken steps to protect our proprietary rights
in our new products. However, the steps we have taken to protect them may not be
sufficient or may not be enforced by a court of law. If we are unable to protect
our proprietary rights, other parties may attempt to copy or otherwise obtain or
use our products or technology. If competitors are able to use our technology,
our ability to compete effectively could be harmed.

 WE HAVE A LIMITED NUMBER OF SUPPLIERS OF RAW MATERIALS; AN INCREASE IN THE
 PRICE OF RAW MATERIALS OR THE INABILITY TO OBTAIN RAW MATERIALS COULD ADVERSELY
 AFFECT OUR RESULTS OF OPERATIONS.

     We currently rely on a limited number of suppliers for certain key
components in the manufacturing of truck trailers, such as landing gear, axles
and specialty steel coil used in DuraPlate(R) panels. The loss of our suppliers
or their inability to meet our price, quality, quantity and delivery
requirements could have a significant impact on our results of operations.

 DISRUPTION OF OUR MANUFACTURING OPERATIONS OR MANAGEMENT INFORMATION SYSTEMS
 WOULD HAVE AN ADVERSE EFFECT ON OUR FINANCIAL CONDITION AND RESULTS OF
 OPERATIONS.

     We manufacture our products at two facilities in Lafayette, Indiana, with
our primary manufacturing facility accounting for approximately 85% of our
manufacturing output. An unexpected disruption in our production at either of
these facilities or in our management information systems for any length of time
would have an adverse effect on our business, financial condition and results of
operations.

                                        5


 THE LOSS OF KEY PERSONNEL COULD ADVERSELY AFFECT OUR RESULTS OF OPERATIONS.

     Many of our executive officers, including our CEO William P. Greubel, CFO
Mark R. Holden and COO Richard J. Giromini, are critical to the management and
direction of our business. Our future success depends, in large part, on our
ability to retain these officers and other capable management personnel. The
unexpected loss of the services of any of our key personnel could have an
adverse effect on the operation of our business, as we may be unable to find
suitable management to replace departing executives on a timely basis.

 THE INABILITY TO REALIZE ADDITIONAL COSTS SAVINGS COULD WEAKEN OUR COMPETITIVE
 POSITION.

     If we are unable to continue to successfully implement our program of cost
reduction and continuous improvement, we may not realize additional anticipated
cost savings, which could weaken our competitive position.

 WE ARE SUBJECT TO CURRENCY EXCHANGE RATE FLUCTUATIONS, WHICH COULD ADVERSELY
 AFFECT OUR FINANCIAL PERFORMANCE.


     We are subject to currency exchange rate risk related to sales through our
factory-owned retail distribution centers in Canada. For the six months ended
June 30, 2004 and the year ended December 31, 2003, currency exchange rate
fluctuations had an unfavorable impact of $0.4 million and a favorable impact of
$5.3 million, respectively, on our results of operations. We cannot assure you
that future currency exchange rate fluctuations will not have an adverse affect
on our results of operations equivalent to or more severe than that for the six
months ended June 30, 2004.


RISKS PARTICULAR TO THE INDUSTRIES IN WHICH WE OPERATE

 OUR BUSINESS IS HIGHLY CYCLICAL, WHICH COULD ADVERSELY AFFECT OUR SALES AND
 RESULTS OF OPERATIONS.

     The truck trailer manufacturing industry historically has been and is
expected to continue to be cyclical, as well as affected by overall economic
conditions. New trailer production for the trailer industry as a whole was
approximately 140,000 in both 2001 and 2002 and totaled approximately 183,000 in
2003. Customers historically have replaced trailers in cycles that run from five
to twelve years, depending on service and trailer type. Poor economic conditions
can adversely affect demand for new trailers and in the past have led to an
overall aging of trailer fleets beyond this typical replacement cycle. Our
business is likely to continue to be adversely affected unless economic
conditions improve.

 SIGNIFICANT COMPETITION IN THE INDUSTRIES IN WHICH WE OPERATE MAY RESULT IN OUR
 COMPETITORS OFFERING NEW OR BETTER PRODUCTS AND SERVICES OR LOWER PRICES, WHICH
 COULD RESULT IN A LOSS OF CUSTOMERS AND A DECREASE IN OUR REVENUES.

     The truck trailer manufacturing industry is highly competitive. We compete
with other manufacturers of varying sizes, some of which may have greater
financial resources than we do. Barriers to entry in the standard truck trailer
manufacturing industry are low. As a result, it is possible that additional
competitors could enter the market at any time. In addition, we believe that the
manufacturing over-capacity and high leverage of some of our competitors, along
with the recent bankruptcies and financial stresses that have affected the
industry, have contributed to significant pricing pressures.

     If we are unable to compete successfully with other trailer manufacturers,
we could lose customers and our revenues may decline. In addition, competitive
pressures in the industry may affect the market prices of our new and used
equipment, which, in turn, may adversely affect our sales margins and results of
operations.

 WE ARE SUBJECT TO EXTENSIVE GOVERNMENTAL LAWS AND REGULATIONS, AND OUR COSTS
 RELATED TO COMPLIANCE WITH, OR OUR FAILURE TO COMPLY WITH, EXISTING OR FUTURE
 LAWS AND REGULATIONS COULD ADVERSELY AFFECT OUR BUSINESS AND RESULTS OF
 OPERATIONS.

     The length, height, width, maximum weight capacity and other specifications
of truck trailers are regulated by individual states. The Federal government
also regulates certain truck tailer safety features, such as lamps, reflective
devices, tires, air-brake systems and rear-impact guards. Changes or
anticipation of changes in these regulations can have a material impact on our
financial results, as our customers may defer

                                        6


customer purchasing decisions and we may have to reengineer products. In
addition, we are subject to various environmental laws and regulations dealing
with the transportation, storage, presence, use, disposal and handling of
hazardous materials, discharge of storm water and underground fuel storage tanks
and may be subject to liability associated with operations of prior owners of
acquired property. If we are found to be in violation of applicable laws or
regulations, it could have an adverse effect on our business, financial
condition and results of operations. Our costs of complying with these or any
other current or future environmental regulations may be significant. In
addition, if we fail to comply with existing or future laws and regulations, we
may be subject to governmental or judicial fines or sanctions.

 A DECLINE IN THE VALUE OF USED TRAILERS COULD ADVERSELY AFFECT OUR RESULTS OF
 OPERATIONS.

     General economic and industry conditions, as well as the supply of used
trailers, influence the value of used trailers. As part of our normal business
practices, we maintain used trailer inventories and have entered into finance
contracts secured by used trailers, as well as residual guarantees and purchase
commitments for used trailers. Declines in the market value for used trailers or
the need to dispose of excess inventories has had, and could in the future have,
an adverse effect on our business, financial condition and results of
operations.

RISKS RELATED TO AN INVESTMENT IN THE NOTES AND COMMON STOCK

 OUR COMMON STOCK HAS EXPERIENCED, AND MAY CONTINUE TO EXPERIENCE, PRICE
 VOLATILITY AND A LOW TRADING VOLUME.

     The trading price of our common stock has been and may continue to be
subject to large fluctuations and, therefore, the trading price of the notes may
fluctuate significantly, which may result in losses to investors. Our stock
price may increase or decrease in response to a number of events and factors,
including:

     - trends in our industry and the markets in which we operate;

     - changes in the market price of the products we sell;

     - the introduction of new technologies or products by us or our
       competitors;

     - changes in expectations as to our future financial performance, including
       financial estimates by securities analysts and investors;

     - operating results that vary from the expectations of securities analysts
       and investors;

     - announcements by us or our competitors of significant contracts,
       acquisitions, strategic partnerships, joint ventures, financings or
       capital commitments;

     - changes in laws and regulations; and

     - general economic and competitive conditions.

     This volatility may adversely affect the prices of our common stock and the
notes regardless of our operating performance. The price of our common stock
also may be adversely affected by the amount of common stock issuable upon
conversion of the notes. Assuming $125 million in aggregate principal amount of
the notes are converted at a conversion price of $19.20, the number of shares of
our common stock outstanding would increase by approximately 6.5 million shares,
or approximately 24%.

     In addition, our common stock has experienced low trading volume in the
past.

 THERE IS A LIMITED TRADING MARKET FOR THE NOTES.

     There is limited market activity in the notes. Although the initial
purchasers of the notes are currently making a market in the notes, they are not
obligated to do so and may discontinue such market making at any time without
notice. In addition, such market making activity will be subject to the limits
imposed by the Securities Act of 1933, as amended and the Securities Exchange
Act of 1934, as amended. Accordingly, there can be no assurance that any market
for the notes will be maintained. If an active market for the notes fails to
develop or

                                        7


be sustained, the trading price of the notes could be materially adversely
affected. The notes are traded on the Portal Market; however, we do not intend
to apply for listing of the notes on any securities exchange.

     The liquidity of the trading market in these notes, and the market price
quoted for these notes, may be materially adversely affected by:

     - changes in the overall market for convertible subordinated securities;

     - changes in our financial performance or prospects;

     - the prospects for companies in our industry generally;

     - the number of holders of the notes;

     - the interest of securities dealers in making a market for the notes; and

     - prevailing interest rates.

 THE NOTES ARE UNSECURED AND EFFECTIVELY SUBORDINATED TO ANY SECURED
 INDEBTEDNESS WE HAVE AND MAY INCUR IN THE FUTURE AND THE LIABILITIES OF OUR
 SUBSIDIARIES.

     The notes are our senior unsecured obligations, effectively junior in right
of payment to our secured debt, to the extent of the assets securing such debt.
In addition, the notes are effectively junior in right of payment to the
indebtedness and other liabilities of our subsidiaries. See "Description of the
Notes -- Ranking."

     In the event that we are declared bankrupt, become insolvent or are
liquidated or reorganized, any debt that ranks ahead of the notes will be
entitled to be paid in full from our assets before any payment may be made with
respect to the notes. Holders of the notes will participate ratably with all
holders of our other senior unsecured indebtedness, based upon the respective
amounts owed to each holder or creditor, in our remaining assets. Upon the
occurrence of any of the foregoing events, we cannot assure you that there will
be sufficient assets to pay amounts due on the notes. As a result, holders of
notes may receive less, ratably, than the holders of any secured indebtedness
that we may then have outstanding.

 WE MAY INCUR ADDITIONAL INDEBTEDNESS RANKING EQUAL TO THE NOTES.

     If we incur any additional debt that ranks equally with the notes,
including trade payables, the holders of that debt will be entitled to share
ratably with you in any proceeds distributed in connection with any insolvency,
liquidation, reorganization, dissolution or other winding-up of us. This may
have the effect of reducing the amount of proceeds paid to holders of notes, if
any.

 WE MAY NOT HAVE THE ABILITY TO RAISE THE FUNDS TO PURCHASE NOTES UPON A CHANGE
 OF CONTROL AS REQUIRED BY THE INDENTURE.

     Upon the occurrence of certain change of control events, each holder of
notes may require us to repurchase all or a portion of its notes at a purchase
price equal to 100% of the principal amount thereof, plus accrued interest. Our
ability to repurchase the notes for cash upon a change of control would be
limited by the terms of certain of our existing debt agreements and may be
limited by the terms of any debt agreements that we enter into in the future.
Currently, our existing debt agreements do not permit such cash payments. Upon a
change of control, we may be required immediately to repay the outstanding
principal, any accrued interest and any other amounts owed by us under our other
debt agreements. We cannot assure you that we would be able to repay amounts
outstanding under our debt agreements, or obtain necessary consents to
repurchase the notes. Any requirement to offer to purchase any outstanding notes
may result in our having to refinance our outstanding indebtedness, which we may
not be able to do on terms favorable to us, if at all.

 WE DO NOT EXPECT TO PAY CASH DIVIDENDS IN THE FORESEEABLE FUTURE.

     Since December 2001, we have not declared or paid cash or other dividends
on our common stock and do not expect to pay cash dividends on our common stock
for the foreseeable future. We currently intend to retain all future earnings
for use in the operation of our business and to fund future growth. In addition,
the terms of
                                        8


our existing debt agreements restrict our ability to pay cash dividends on our
common stock. We are permitted to pay preferred stock dividends on our
outstanding Series B Preferred so long as no default or event of default exists
at the time of the distribution.

 ARTHUR ANDERSEN LLP, OUR FORMER AUDITORS, AUDITED CERTAIN FINANCIAL INFORMATION
 INCLUDED IN THIS PROSPECTUS. IN THE EVENT SUCH FINANCIAL INFORMATION IS LATER
 DETERMINED TO CONTAIN FALSE STATEMENTS, YOU MAY BE UNABLE TO RECOVER DAMAGES
 FROM ARTHUR ANDERSEN LLP.

     Arthur Andersen LLP completed its audit of our financial statements for the
year ended December 31, 2001, and issued its report with respect to such
financial statements dated April 12, 2002. On March 14, 2002, Arthur Andersen
was indicted on, and on June 15, 2002 Arthur Andersen was convicted of, federal
obstruction of justice charges arising from the U.S. Government's investigation
of Enron Corporation.

     On May 30, 2002, we dismissed Arthur Andersen as our independent auditors
and we appointed Ernst & Young LLP as our independent auditors for fiscal year
2002. We had no disagreements with Arthur Andersen on any matter of accounting
principle or practice, financial statement disclosure or auditing scope or
procedure. Arthur Andersen audited the financial statements that we include in
this prospectus as of December 31, 2001 and for the years ending December 31,
2000 and 2001.

     Arthur Andersen has stopped conducting business before the SEC and has
limited assets available to satisfy the claims of creditors. As a result, you
may be limited in your ability to recover damages from Arthur Andersen under
federal or state law if it is later determined that there are false statements
contained in this prospectus relating to or contained in financial data audited
by Arthur Andersen.

is disclosed in the above table, in thousands.

     We present below the pro forma ratio of our earnings to combined fixed
charges and preferred stock dividends for the year ended December 31, 2003. The
pro forma ratio has been prepared to illustrate the impact of the sale of
certain assets of our rental and leasing business and wholesale aftermarket
parts business and refinancings of our debt through the sale of $125 million of
3.25% senior unsecured convertible notes and a three-year $222 million bank
facility. The asset divestiture and refinancings are described in the Company's

     We will not receive any proceeds from the sale of the notes or common stock
by the selling holders.

                                SELLING HOLDERS

     The notes were originally issued by us and sold to the initial purchasers
in a transaction exempt from the registration requirements of the Securities Act
of 1933 and were resold by the initial purchasers to persons reasonably believed
by the initial purchasers to be qualified institutional buyers or other
institutional accredited investors, in transactions exempt from the registration
requirements. Selling holders, including their transferees, pledgees or donees
or their successors, may from time to time offer and sell pursuant to this
prospectus any or all of the notes and common stock into which the notes are
convertible.

     The following table sets forth information with respect to the selling
holders and the principal amounts of notes beneficially owned by each selling
holder that may be offered under this prospectus. The information is based on
information provided by or on behalf of the selling holders to us in a selling
holder questionnaire. Any or all of the notes listed below and the common stock
into which the notes are convertible may be offered for sale pursuant to this
prospectus by the selling holders from time to time. Accordingly, no estimate
can be given as to the amounts of notes or common stock that will be held by the
selling holders upon consummation of any such sales. In addition, the
information relating to ownership of notes by the selling holders listed in the
table below may change as a result of the acquisition, sale or transfer, in
transactions exempt from the registration requirements of the Securities Act, of
some or all of their notes since the date as of which the information in the
table is presented.

     Information about selling holders may change over time. Any changed
information supplied to us will be set forth in prospectus supplements or
post-effective amendments, as may be appropriate. Holders of the notes or the
common stock into which the notes are convertible who are not named in the table
below will be identified in a new prospectus that would be included in a
post-effective amendment to the registration statement of which this prospectus
forms a part.

---------------

 *  This selling security holder has informed us that it (1) is an affiliate of
    a broker-dealer, (2) purchased the securities in the ordinary course of
    business, and (3) at the time of purchase, had no agreements or
    understandings, directly or indirectly, with any person to distribute the
    securities.

(1)  Includes common stock into which the notes are convertible.

(2)  Assumes a conversion price of $19.20 per share, which is equal to a
     conversion rate of approximately 52.0833 shares of common stock per $1,000
     principal amount of notes, subject to adjustment, and a cash payment in
     lieu of any fractional interest.

(3)  This entity is either an investment company or a portfolio of an investment
     company registered under Section 8 of the Investment Company Act of 1940,
     as amended, or a private investment account advised by Fidelity Management
     & Research Company ("FMR Co."). FMR Co. is a Massachusetts corporation and
     an investment advisor registered under Section 203 of the Investment
     Advisers Act of 1940, as amended, and provides investment advisory services
     to each of such Fidelity entities identified above, and to other registered
     investment companies and to certain other funds which are generally offered
     to a limited group of investors. FMR Co. is a wholly-owned subsidiary of
     FMR Corp., a Delaware corporation.

(4)  Pioneer U.S. High Yield Corp. Bond Sub Fund is managed by Pioneer
     Investment Management Inc. Pioneer Investment Management Inc. is a
     subsidiary of Pioneer Global Asset Management SPA, which has owned over 5%
     of the Company's equity securities since August 14, 2003. As of December
     31, 2003, Pioneer Global Asset Management SPA owned 7.46% of the Company's
     equity securities.




     Except as disclosed above in note 3 with respect to Pioneer High Yield Fund
and Pioneer U.S. High Yield Corp. Bond Sub Fund, none of the selling holders nor
any of their affiliates, officers, directors or principal equity holders has
held any position or office or has had any material relationship with us within
the past three years. The selling holders purchased the notes from the initial
purchasers in private transactions on August 1, 2003.

     The conversion rate, and, therefore, the number of shares of common stock
issuable upon conversion of the notes is subject to adjustment under certain
circumstances and may increase or decrease. To the extent that the resale of any
common shares issuable as a result of a conversion rate adjustment would not be
deemed registered under Rule 416 pursuant to the Securities Act, we would file a
new registration statement to cover the resale of such shares.

                              PLAN OF DISTRIBUTION

     The selling holders and their successors, including their transferees,
pledgees or donees or their successors, may sell the notes and the common stock
into which the notes are convertible directly to purchasers or through
underwriters, broker-dealers or agents, who may receive compensation in the form
of discounts, concessions or commissions from the selling holders or the
purchasers. These discounts, concessions or commissions as to any particular
underwriter, broker-dealer or agent may be in excess of those customary in the
types of transactions involved.

     The notes and the common stock into which the notes are convertible may be
sold in one or more transactions at fixed prices, at prevailing market prices at
the time of sale, at prices related to the prevailing market prices, at varying
prices determined at the time of sale, or at negotiated prices. These sales may
be effected in transactions, which may involve crosses or block transactions:

     - on any national securities exchange or quotation service on which the
       notes or the common stock may be listed or quoted at the time of sale;

     - in the over-the-counter market;

     - in transactions otherwise than on these exchanges or systems or in the
       over-the-counter market;

                                        12


     - through the writing of options, whether the options are listed on an
       options exchange or otherwise; or

     - through the settlement of short sales.

     In connection with the sale of the notes and the common stock into which
the notes are convertible or otherwise, the selling holders may enter into
hedging transactions with broker-dealers or other financial institutions, which
may in turn engage in short sales of the notes or the common stock into which
the notes are convertible in the course of hedging the positions they assume.
The selling holders may also sell the notes or the common stock into which the
notes are convertible short and deliver these securities to close out their
short positions, or loan or pledge the notes or the common stock into which the
notes are convertible to broker-dealers that in turn may sell these securities.

     The aggregate proceeds to the selling holders from the sale of the notes or
common stock into which the notes are convertible offered by them will be the
purchase price of the notes or common stock less discounts and commissions, if
any. Each of the selling holders reserves the right to accept and, together with
their agents from time to time, to reject, in whole or in part, any proposed
purchase of notes or common stock to be made directly or through agents. We will
not receive any of the proceeds from this offering.

     Our outstanding common stock is listed on the New York Stock Exchange. We
do not intend to list the notes for trading on the New York Stock Exchange, any
other national securities exchange or on the Nasdaq National Market and can give
no assurance about the development of any trading market for the notes.

     In order to comply with the securities laws of some states, if applicable,
the notes and common stock into which the notes are convertible may be sold in
these jurisdictions only through registered or licensed brokers or dealers. In
addition, in some states the notes and common stock into which the notes are
convertible may not be sold unless they have been registered or qualified for
sale or an exemption from registration or qualification requirements is
available and is complied with.

     The selling holders may be "underwriters" within the meaning of Section
2(11) of the Securities Act. Selling holders that are broker-dealers and
underwriters, broker-dealers or other agents that participate in the sale of the
notes and common stock into which the rates are convertible are "underwriters"
within the meaning of Section 2(11) of the Securities Act. Any discounts,
commissions, concessions or profit they earn on any resale of the shares may be
underwriting discounts and commissions under the Securities Act. Selling holders
who are "underwriters" within the meaning of Section 2(11) of the Securities Act
will be subject to the prospectus delivery requirements of the Securities Act.
Aristeia Trading LLC and KBC Financial Products USA Inc. have informed us that
they are registered broker-dealers, and, as a result, they are "underwriters" in
connection with their sale of notes and the underlying shares of common stock.
The selling stockholders who are affiliates of broker-dealers have confirmed
that they purchased the notes in the ordinary course of business and, at the
time of purchase, had no agreement or understandings, directly or indirectly
with any person to distribute the notes or the common stock into which the notes
are convertible.

     The selling holders have acknowledged that they understand their
obligations to comply with the provisions of the Exchange Act and the rules
thereunder relating to stock manipulation, particularly Regulation M, which may
limit the timing of purchases and sales of any of the notes by the selling
holders and any such other person. In addition, Regulation M may restrict the
ability of any person engaged in the distribution of the notes to engage in
market-making activities with respect to the particular notes being distributed
for a period of up to five business days prior to the commencement of the
distribution. This may affect the marketability of the notes and the preferred
notes and the ability of any person or entity to engage in market-making
activities with respect to the notes.

     In addition, any securities covered by this prospectus which qualify for
sale pursuant to Rule 144 or Rule 144A of the Securities Act may be sold under
Rule 144 or Rule 144A rather than pursuant to this prospectus. A selling holder
may not sell any notes or common stock described in this prospectus and may not
transfer, devise or gift these securities by other means not described in this
prospectus.

     On August 1, 2003, we issued and sold the notes to two initial purchasers
in transactions exempt under Section 4(2) of the Securities Act, and the initial
purchasers subsequently resold them to persons reasonably

                                        13


believed to be qualified institutional buyers in a transaction exempt from
registration in reliance on Rule 144A of the Securities Act.

     To the extent required, the specific notes or common stock to be sold, the
names of the selling holders, the respective purchase prices and public offering
prices, the names of any agent, dealer or underwriter, and any applicable
commissions or discounts with respect to a particular offer will be set forth in
an accompanying prospectus supplement or, if appropriate, a post-effective
amendment to the registration statement of which this prospectus is a part.

     We entered into a registration rights agreement for the benefit of holders
of the notes to register their notes and common stock under applicable federal
and state securities laws under specific circumstances and at specific times.
The registration rights agreement provides for cross-indemnification of the
selling holders and Wabash and their respective directors, officers and
controlling persons against specific liabilities in connection with the offer
and sale of the notes and the common stock, including liabilities under the
Securities Act. We will pay substantially all of the expenses incurred by the
selling holders incident to the offering and sale of the notes and the common
stock.

                            DESCRIPTION OF THE NOTES

     The notes were issued under an indenture between us and Wachovia Bank,
National Association, as trustee, dated August 1, 2003. The terms of the notes
include those provided in the indenture and this description of the notes also
includes a description of certain terms provided in the registration rights
agreement, which we entered into with the initial purchasers. As used in this
section, the words "we," "us," "our" or "Wabash" refer to Wabash National
Corporation.

     While the following is a description of the material provisions of the
notes it is not a complete description of all terms and should be read in
conjunction with the notes, the indenture and the registration rights agreement.
We will provide you with a copy of any of the foregoing documents without charge
upon request.

GENERAL

     The notes are our general unsecured and unsubordinated obligations and are
convertible into our common stock as described under "-- Conversion Rights"
below. The notes are limited to $125,000,000 aggregate principal amount and
mature on August 1, 2008, unless earlier repurchased by us at the option of the
holder upon the occurrence of a Change of Control (as defined below). The notes
are not redeemable prior to maturity.

     The notes bear cash interest at a rate of 3.25% per annum from August 1,
2003, or from the most recent interest payment date to which interest has been
paid or duly provided for. We will pay cash interest semi-annually in arrears on
August 1 and February 1 of each year to holders of record at the close of
business on the preceding July 15 and January 15, respectively, beginning
February 1, 2004 and on the maturity date of August 1, 2008, to the holder to
whom we pay the principal. We may pay interest on notes represented by
certificated notes by check mailed to such holders. However, a holder of notes
with an aggregate principal amount in excess of $5,000,000 will be paid by wire
transfer in immediately available funds at the election of such holder. Interest
will be computed on the basis of a 360-day year comprised of twelve 30-day
months. Each payment of cash interest on the notes will include interest accrued
through the day before the applicable interest payment date (or purchase date or
conversion date, as the case may be). Interest will cease to accrue on a note
upon its maturity, conversion or purchase by us upon a Change of Control.

     Principal will be payable, and the notes may be presented for conversion,
registration of transfer and exchange, without service charge, at our office or
agency in New York City, which shall initially be the office or agency of the
trustee in New York, New York. See "-- Form, Denomination and Registration"
below.

     The indenture does not contain any financial covenants or any restrictions
on the payment of dividends, the repurchase of our securities or the incurrence
of indebtedness. The indenture also does not contain any covenants or other
provisions that afford protection to holders of notes in the event of a highly
leveraged

                                        14


transaction or a Change of Control of Wabash except to the extent described
under "-- Change of Control Permits Purchase of Notes at the Option of the
Holder" below.

CONVERSION RIGHTS

     The holders of notes may, at any time prior to the close of business on the
final maturity date of the notes, convert any outstanding notes (or portions
thereof) into our common stock, initially at a conversion price of $19.20 per
share of common stock, which is equal to a conversion rate of 52.0833 shares of
common stock per $1,000 principal amount of notes. The notes were initially
convertible only after the occurrence of one of the conditions set forth below.
The conversion rate is subject to adjustment upon the occurrence of events
described below. Holders may convert notes only in denominations of $1,000 and
whole multiples of $1,000. Except as described below, no adjustment will be made
on conversion of any notes for interest accrued thereon or dividends paid on any
common stock. Notwithstanding the above, if notes are converted after a record
date but prior to the next succeeding interest payment date, holders of such
notes at the close of business on the record date will receive the interest
payable on such notes on the corresponding interest payment date notwithstanding
the conversion. Such notes, upon surrender for conversion, must be accompanied
by funds equal to the amount of interest payable on the principal amount of
notes so converted. We are not required to issue fractional shares of common
stock upon conversion of notes and instead will pay a cash adjustment based upon
the market price of the common stock on the last trading day before the date of
the conversion.

     A holder may exercise the right of conversion by delivering the note to be
converted to the specified office of a conversion agent, with a completed notice
of conversion, together with any funds that may be required as described in the
preceding paragraph. Beneficial owners of interests in a global note may
exercise their right of conversion by delivering to the Depository Trust Company
(DTC) the appropriate instruction form for conversion pursuant to DTC's
conversion program. The conversion date will be the date on which the notes, the
notice of conversion and any required funds have been so delivered. A holder
delivering a note for conversion will not be required to pay any taxes or duties
relating to the issuance or delivery of the common stock for such conversion,
but will be required to pay any tax or duty which may be payable relating to any
transfer involved in the issuance or delivery of the common stock in a name
other than the holder of the note. Certificates representing shares of common
stock will be issued or delivered only after all applicable taxes and duties, if
any, payable by the holder have been paid. If any note is converted prior to the
expiration of the holding period applicable for sales thereof under Rule 144(k)
under the Securities Act (or any successive provision), the common stock
issuable upon conversion will not be issued or delivered in a name other than
that of the holder of the note, unless the applicable restrictions on transfer
have been satisfied.

 CONVERSION RATE ADJUSTMENTS

     The initial conversion rate will be adjusted for the following events:

     - the issuance of Wabash common stock as a dividend or distribution on
       Wabash common stock, in which case the conversion price will be reduced
       by multiplying the conversion rate by a fraction the numerator of which
       is the number of shares of Wabash common stock outstanding prior to the
       date of determination of the dividend or distribution and the denominator
       of which is the sum of the new Wabash common stock shares issued and the
       shares used in calculating the numerator;

     - subdivisions, combinations and certain reclassification of Wabash common
       stock resulting in the increase or decrease in the number of shares
       outstanding, in which case the conversion rate shall be adjusted
       proportionately;

     - the issuance to all holders of Wabash common stock of certain rights or
       warrants to purchase Wabash common stock (or securities convertible into
       Wabash common stock) at a price less than (or having a conversion price
       per share less than) the current market price of Wabash common stock
       taking into account the consideration received for such rights and
       warrants, in which case the conversion rate shall be adjusted by
       multiplying it by a fraction the numerator of which is the number of
       shares of Wabash common stock outstanding plus the number of shares which
       the aggregate offering price of the shares offered for subscription or
       purchase (or the aggregate conversion price of the convertible securities
                                        15


       offered, if applicable) would purchase at the current market price, and
       the denominator of which is the number of shares of Wabash common stock
       outstanding plus the number of shares offered for subscription or
       purchase;

     - the dividend or other distribution to all holders of Wabash common stock
       or shares of Wabash capital stock (other than common stock) or evidences
       of indebtedness or assets (including securities, but excluding (A) those
       rights and warrants referred to above, (B) dividends and distributions in
       connection with a reclassification, change, consolidation, merger,
       combination, sale or conveyance resulting in a change in the conversion
       consideration pursuant to the second succeeding paragraph or (C)
       dividends or distributions paid exclusively in cash), in which case,
       unless we reserve securities for distribution to the holders of the notes
       upon conversion of the notes, the conversion rate will be adjusted by
       multiplying it by a fraction, the numerator of which shall be the current
       market price of Wabash common stock prior to the dividend or the
       distribution less the fair market value of the dividend or distribution
       per share of outstanding common stock, and the denominator of which shall
       be the current market price of Wabash Common Stock;

     - a dividend or other distribution consisting exclusively of cash to all
       holders of Wabash common stock, in which case the conversion rate shall
       be adjusted by multiplying it by a fraction the numerator of which shall
       be equal to the current market price of Wabash common stock less an
       amount equal to the quotient of (x) the amount distributed and (y) the
       number of shares of Wabash common stock outstanding, and the denominator
       of which shall be equal to the current market price; and

     - the purchase of Wabash common stock pursuant to a tender offer made by
       Wabash or any of its subsidiaries, to the extent that the same involves
       an aggregate consideration that, together with any cash and the fair
       market value of any other consideration paid in any other tender offer by
       Wabash or any of its subsidiaries for Wabash common stock expiring within
       the 12 months preceding such tender offer for which no adjustment has
       been made, exceeds ten percent of our market capitalization on the
       expiration of such tender offer, in which case the conversion rate shall
       be adjusted by multiplying it by a fraction the numerator of which shall
       be the shares of Wabash common stock outstanding at the expiration of the
       tender offer times the market price after the expiration of the tender
       offer, and the denominator of which shall be the sum of (x) the fair
       market value of the aggregate consideration paid in respect of the shares
       tendered and accepted for payment and (y) the product of the number of
       shares outstanding at the expiration of the tender offer and the current
       market price after the expiration of the tender offer.

     No adjustment in the conversion rate will be required unless such
adjustment would require a change of at least one percent in the conversion rate
then in effect at such time. Any adjustment that would otherwise be required to
be made shall be carried forward and taken into account in any subsequent
adjustment. Except as stated above, the conversion rate will not be adjusted for
the issuance of our common stock or any securities convertible into or
exchangeable for our common stock or carrying the right to purchase any of the
foregoing.

     In the case of:

     - any reclassification or change of Wabash common stock (other than changes
       resulting from a subdivision or combination) or

     - a consolidation, merger or combination involving Wabash or a sale or
       conveyance to another corporation of all or substantially all of Wabash's
       property and assets,

in each case as a result of which holders of Wabash common stock are entitled to
receive stock, other securities, other property or assets (including cash or any
combination thereof) with respect to or in exchange for Wabash common stock, the
holders of the notes then outstanding will be entitled thereafter to convert
those notes into the kind and amount of shares of stock, other securities or
other property or assets (including cash or any combination thereof) which they
would have owned or been entitled to receive upon such reclassification, change,
consolidation, merger, combination, sale or conveyance had such notes been
converted into Wabash common stock immediately prior to such reclassification,
change, consolidation, merger, combination, sale or conveyance.
                                        16


     We may not become a party to any such transaction unless its terms are
consistent with the foregoing. If a taxable distribution to holders of Wabash
common stock or other transaction occurs which results in any adjustment of the
conversion price, the holders of notes may, in certain circumstances, be deemed
to have received a distribution subject to U.S. income tax as a dividend. In
certain other circumstances, the absence of an adjustment may result in a
taxable dividend to the holders of common stock. See the section of this
prospectus entitled "Material United States Federal Income Tax Considerations."

     Wabash may make additional reductions to the conversion price as the board
of directors considers to be advisable to avoid or diminish any income tax to
holders of common stock or rights to purchase common stock resulting from any
dividend or distribution of stock.

     We may from time to time, to the extent permitted by law, reduce the
conversion price of the notes by any amount for any period of at least 20 days.
In that case we will give at least 15 days' notice of such decrease. We may make
such reductions in the conversion price, in addition to those set forth above,
as the board of directors deems in our best interests, which determination will
be conclusive.

CONDITIONS TO CONVERSION

     The notes were not convertible until the occurrence of one of the
conditions described below. As of January 1, 2004, the condition described below
under "Conversion upon Satisfaction of Sale Price Conditions" was met and the
notes are now convertible, at the option of the holder, at any time prior to the
close of business on the final maturity date of the notes.

     - Conversion upon Satisfaction of Sale Price Conditions.  Holders may
       surrender notes for conversion into shares of Wabash common stock in any
       fiscal quarter commencing after September 30, 2003 if, as of the last day
       of the preceding fiscal quarter, the sale price of our common stock for
       at least 20 trading days in a period of 30 consecutive trading days
       ending on the last trading day of such preceding fiscal quarter is more
       than 110% of the conversion price per share of common stock on the last
       trading day of such preceding fiscal quarter. Holders may also surrender
       notes for conversion into shares of Wabash common stock if the sale price
       of our common stock for at least 20 trading days in a period of 30
       consecutive trading days ending on the last trading day prior to the
       final maturity date of the notes is greater than 110% of the conversion
       price per share of common stock on the last trading day prior to the
       maturity date. If either of foregoing conditions is satisfied, then the
       notes will be convertible at any time at the option of the holder,
       through the close of business on the final maturity date of the notes.

     The sale price of our common stock on any trading day means the closing per
     share sale price (or if no closing sale price is reported, the average of
     the bid and ask prices or, if more than one in either case, the average of
     the average bid and the average ask prices) on such date on the principal
     national securities exchange on which the common stock is listed, or if our
     common stock is not listed on a national securities exchange, as reported
     by the Nasdaq System or otherwise as provided in the indenture.

     As noted above, this condition was satisfied in the fiscal quarter ended
     December 31, 2003, and, as a result, the notes are now convertible.

     - Conversion upon Satisfaction of Trading Price Condition.  Holders may
       surrender notes for conversion into shares of Wabash common stock
       following any ten consecutive trading-day period in which the average of
       the trading prices per $1,000 principal amount of notes for that ten
       trading-day period was less than 95% of the average conversion value for
       the notes during that period; provided, however, a holder may not convert
       its notes if the average closing sale price of our common stock for such
       ten consecutive trading-day period was between the then current
       conversion price per share of common stock and 110% of the then
       applicable conversion price per share of common stock. If the foregoing
       condition is satisfied, then the notes will be convertible at any time at
       the option of the holder, through the close of business on the final
       maturity date of the notes.

     The conversion value of a note is equal to the product of the closing sale
     price for shares of our common stock on a given day multiplied by the then
     current conversion rate, which is the number of
                                        17


shares of common stock into which each note is then convertible. The trading
price of the notes on any date of determination means the average of the
secondary market bid quotations per $1,000 principal amount of notes obtained by
      us or the trustee for $2,500,000 principal amount of notes at
      approximately 3:30 p.m., New York City time, on such determination date
      from two independent nationally recognized securities dealers we select,
      provided that if at least two such bids cannot reasonably be obtained by
      us or the trustee, but one such bid is obtained, then this one bid shall
      be used.

     - Conversion upon Occurrence of Specified Corporate Transactions.  If we
       are party to a consolidation, merger or binding share exchange or a
       transfer of all or substantially all of our assets and, as a result,
       holders of our common stock would be entitled to receive stock, other
       securities, other property or assets (including cash or any combination
       thereof) with respect to or in exchange for our common stock, a note may
       be surrendered for conversion at any time from and after the date which
       is 15 days prior to the anticipated effective date of the transaction
       until 15 days after the actual effective date of such transaction, and at
       the effective date, the right to convert a note into common stock will be
       deemed to have changed into a right to convert it into the kind and
       amount of securities, cash or other assets of Wabash or another person
       which the holder would have received if the holder had converted the
       holder's notes immediately prior to the transaction. If such transaction
       also constitutes a change of control of Wabash, the holder will be able
       to require us to purchase all or a portion of such holder's notes as
       described under "-- Change in Control Permits Purchase of Notes at the
       Option of the Holder."

RANKING


     The notes are our senior unsecured and unsubordinated obligations. The
notes rank on a parity in right of payment with all of our existing and future
senior unsecured and unsubordinated indebtedness. However, the notes are
effectively subordinated to our existing and future secured indebtedness as to
the assets securing such indebtedness. As of June 30, 2004, we had total
indebtedness of $213 million (of which $85 million was secured indebtedness).


     In addition, the notes are effectively subordinated to all existing and
future liabilities of our subsidiaries. Our cash flow and consequent ability to
meet our debt obligations depends in part on the earnings of our subsidiaries,
and on dividends and other payments from our subsidiaries. Under certain
circumstances, contractual and legal restrictions, as well as the financial
condition and operating requirements of our subsidiaries, could limit our
ability to obtain cash from its subsidiaries for the purpose of meeting debt
service obligations, including the payment of principal and interest on the
notes. Any rights to receive assets of any subsidiary upon its liquidation or
reorganization and the consequent right of the holders of the notes to
participate in those assets will be subject to the claims of that subsidiary's
creditors, including trade creditors, except to the extent that Wabash is
recognized as a creditor of that subsidiary, in which case its claims would
still be subordinate to any security interests in the assets of that subsidiary.

CHANGE OF CONTROL PERMITS PURCHASE OF NOTES AT THE OPTION OF THE HOLDER

     If a Change of Control occurs, each holder of notes will have the right to
require us to repurchase all of that holder's notes, or any portion of those
notes that is equal to $1,000 or a whole multiple of $1,000, on the date that is
30 days after the date we give notice at a repurchase price equal to 100 percent
of the aggregate principal amount of the notes to be repurchased, together with
interest accrued and unpaid to, but excluding, the repurchase date. Instead of
paying the repurchase price in cash, we may pay the repurchase price in shares
of our common stock if we so elect in the notice referred to below. The number
of shares of common stock a holder will receive will equal the repurchase price
divided by 95 percent of the average of the closing sale prices of the
applicable common stock for the five trading days immediately preceding and
including the third day prior to the repurchase date. However, we may not pay in
common stock unless we satisfy certain conditions prior to the repurchase date
as provided in the indenture.

     Within 15 days after the occurrence of a Change of Control, we are required
to give notice to all holders of notes, as provided in the indenture, of the
occurrence of the Change of Control and of their resulting

                                        18


repurchase right. We must also deliver a copy of our notice to the trustee. To
exercise the repurchase right, a holder of notes must deliver prior to or on the
repurchase date irrevocable written notice to the trustee of the holder's
exercise of its repurchase right, together with the notes with respect to which
the right is being exercised. A "Change of Control" will be deemed to have
occurred when the following has occurred:

     - our common stock (or other common stock into which the notes are
       convertible) is no longer traded on the New York Stock Exchange or the
       Nasdaq National Market;

     - any "person" or "group" (as such terms are used in Sections 13(d) and
       14(d) of the Exchange Act), acquires the beneficial ownership (as defined
       in Rules 13d-3 and 13d-5 under the Exchange Act, except that a person
       shall be deemed to have "beneficial ownership" of all securities that
       such person has the right to acquire, whether such right is exercisable
       immediately or only after the passage of time), directly or indirectly,
       through a purchase, merger or other acquisition transaction, of 50% or
       more of the total voting power of the total outstanding voting stock of
       Wabash other than an acquisition by us, any of our subsidiaries or any of
       our employee benefit plans;

     - Wabash consolidates with, or merges with or into, another person or
       conveys, transfers, leases or otherwise disposes in one or a series of
       related transactions of all or substantially all of its assets to any
       person, or any person consolidates with or merges with or into Wabash,
       other than:

     - any transaction (i) that does not result in any reclassification,
       conversion, exchange or cancellation of outstanding shares of Wabash's
       capital stock and (ii) pursuant to which holders of Wabash's capital
       stock immediately prior to the transaction have the entitlement to
       exercise, directly or indirectly, 50% or more of the total voting power
       of all shares of Wabash's capital stock entitled to vote generally in the
       election of directors of the continuing or surviving person immediately
       after the transaction; and

     - any merger solely for the purpose of changing Wabash's jurisdiction of
       incorporation and resulting in a reclassification, conversion or exchange
       of outstanding shares of common stock solely into shares of common stock
       of the surviving entity;

     - during any consecutive two-year period, individuals who at the beginning
       of that two-year period constituted the board of directors of Wabash
       (together with any new directors whose election to such board of
       directors, or whose nomination for election by stockholders, was approved
       by a vote of a majority of the directors 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 constitute a majority of the board of directors of Wabash then in
       office; or

     - Wabash's stockholders pass a special resolution approving a plan of
       liquidation or dissolution and no additional approvals of stockholders
       are required under applicable law to cause a liquidation or dissolution.

     However, a Change of Control will not be deemed to have occurred if:

     - the daily market price per share of Wabash common stock for any five
       trading days within the period of 10 consecutive trading days immediately
       after the later of the Change of Control or the public announcement of
       the Change of Control (in the case of a Change of Control under the
       second bullet point above) or the period of 10 consecutive trading days
       ending immediately before the Change of Control (in the case of a Change
       of Control under the third bullet point above) shall equal or exceed 110%
       of the conversion price of the notes in effect on the date prior to the
       Change of Control or the public announcement of the Change of Control, as
       applicable; or

     - all of the consideration (excluding cash payments for fractional shares
       and cash payments made pursuant to dissenters' appraisal rights) in the
       transaction or transactions constituting the Change of Control under the
       second and third bullet points above consists of shares of common stock
       that are, or upon issuance will be, traded on the New York Stock Exchange
       or the American Stock Exchange or quoted on the Nasdaq National Market
       and as a result of such transaction or transactions the notes become
       convertible solely into such common stock.

                                        19


     The definition of Change of Control includes a phrase relating to the
conveyance, transfer, lease or other disposition of "all or substantially all"
of Wabash's assets. There is no precise established definition of the phrase
"substantially all" under applicable law. Accordingly, the ability of a holder
of notes to require us to repurchase such notes as a result of a conveyance,
transfer, lease or other disposition of less than all of Wabash's assets may be
uncertain.

     Our right to pay the repurchase price in common stock is subject to our
satisfying various conditions, including:

     - the registration of the common stock under the Securities Act and the
       Exchange Act, if required; and

     - any necessary qualifications under applicable state securities law or the
       availability of an exemption from such qualification and registration.

If such conditions are not satisfied with respect to a holder prior to the close
of business on the repurchase date, we will pay the repurchase price of the
notes to the holder entirely in cash. Such cash payment currently is not
permitted under our existing debt agreements. We may not change the form of
consideration to be paid for the notes once we have given the notice that we are
required to give to holders of notes, except as described in the first sentence
of this paragraph.

     We will comply with the provisions of any tender offer rules under the
Exchange Act that may then be applicable, and will file any schedule required
under the Exchange Act in connection with any offer by us to purchase notes at
the option of the holders of notes upon a Change of Control. In some
circumstances, the Change of Control purchase feature of the notes may make more
difficult or discourage a takeover of us and thus the removal of incumbent
management. The Change of Control purchase feature, however, is not the result
of management's knowledge of any specific effort to accumulate shares of common
stock or to obtain control of us by means of a merger, tender offer,
solicitation or otherwise, or part of a plan by management to adopt a series of
anti-takeover provisions. Instead, the Change of Control purchase feature is the
result of negotiations between us and the initial purchasers.

     We may, to the extent permitted by applicable law, at any time purchase the
notes in the open market or by tender at any price or by private agreement. Any
note so purchased by us may, to the extent permitted by applicable law, be
reissued or resold or may be surrendered to the trustee for cancellation. Any
notes surrendered to the trustee may not be reissued or resold and will be
canceled promptly.

     The foregoing provisions would not necessarily protect holders of the notes
if highly leveraged or other transactions involving us occur that may adversely
affect holders. Our ability to repurchase notes upon the occurrence of a Change
of Control is subject to important limitations. Under our existing credit
agreements, we would not be permitted to repurchase notes for cash unless prior
to any such payment we either repay our indebtedness subject to such
restrictions, refinance such debt on other terms or obtain a waiver from such
lenders. In addition, the occurrence of a Change of Control would likely cause
an event of default under the terms of certain of our existing debt agreements
and could cause an event of default under the terms of any debt agreements we
may enter into in the future. Further, we cannot assure you that we would have
the financial resources, or would be able to arrange financing, to pay the
repurchase price for all the notes that might be delivered by holders of notes
seeking to exercise the repurchase right. Any failure by us to repurchase the
notes when required following a Change of Control would result in an event of
default under the indenture. Any such default, in turn, would cause a default
under certain of our existing debt agreements, and may cause a default under any
debt agreements we may enter into in the future.

EVENTS OF DEFAULT

     Each of the following would constitute an event of default under the
indenture:

          (1) our failure to pay when due the principal of or premium, if any,
     on any of the notes at maturity or exercise of a repurchase right or
     otherwise;

          (2) our failure to pay an installment of interest (including
     liquidated damages, if any) on any of the notes for 30 days after the date
     when due;
                                        20


          (3) failure by us to deliver shares of common stock, together with
     cash instead of fractional shares, when those shares of common stock, or
     cash instead of fractional shares, are required to be delivered following
     conversion of a note, and that default continues for 10 days;

          (4) failure by us to give the notice regarding a Change of Control
     within 15 days of the occurrence of the Change of Control;

          (5) our failure to perform or observe any other term, covenant or
     agreement contained in the notes or the indenture for a period of 60 days
     after written notice of such failure, requiring us to remedy the same,
     shall have been given to us by the trustee or to us and the trustee by the
     holders of at least 25% in aggregate principal amount of the notes then
     outstanding;

          (6) in the event of either (a) our failure or the failure of any of
     our significant subsidiaries to make any payment by the end of the
     applicable grace period, if any, after the final scheduled payment date for
     such payment with respect to any indebtedness for borrowed money in an
     aggregate principal amount in excess of $10 million, or (b) the
     acceleration of indebtedness for borrowed money of the company or any of
     our significant subsidiaries in an aggregate amount in excess of $10
     million because of a default with respect to such indebtedness, without
     such indebtedness referred to in either (a) or (b) above having been
     discharged, cured, waived, rescinded or annulled, for a period of 30 days
     after written notice to us by the trustee or to us and the trustee by
     holders of at least 25% in aggregate principal amount of the notes then
     outstanding; and

          (7) certain events of our bankruptcy, insolvency or reorganization.

     The term "significant subsidiary" means a subsidiary, including its
subsidiaries, that meets any of the following conditions:

     - Wabash's and its other subsidiaries' investments in and advances to the
       subsidiary exceed 10% of the total assets of Wabash and its subsidiaries
       consolidated as of the end of the most recently completed fiscal year;

     - Wabash's and its other subsidiaries' proportionate share of the total
       assets (after intercompany eliminations) of the subsidiary exceeds 10% of
       the total assets of Wabash and its subsidiaries consolidated as of the
       end of the most recently completed fiscal year; or

     - Wabash's and its other subsidiaries' equity in the income from continuing
       operations before income taxes, extraordinary items and cumulative effect
       of a change in accounting principle of the subsidiary exceeds 10% of such
       income of Wabash and its subsidiaries consolidated for the most recently
       completed fiscal year.

     The indenture provides that the trustee shall, within 90 days of the
occurrence of a default, give to the registered holders of the notes notice of
all uncured defaults known to it, but the trustee shall be protected in
withholding such notice if it, in good faith, determines that the withholding of
such notice is in the best interest of such registered holders, except in the
case of a default in the payment of the principal of, or premium, if any, or
interest on, any of the notes when due or in the payment of any repurchase
obligation.

     If an event of default specified in clause (7) above occurs and is
continuing, then automatically the principal of all the notes and the interest
thereon shall become immediately due and payable. If an event of default shall
occur and be continuing, other than with respect to clause (7) above (the
default not having been cured or waived as provided under "-- Modifications and
Waiver" below), the trustee or the holders of at least 25% in aggregate
principal amount of the notes then outstanding may declare the notes due and
payable at their principal amount together with accrued interest, and thereupon
the trustee may, at its discretion, proceed to protect and enforce the rights of
the holders of notes by appropriate judicial proceedings. Such declaration may
be rescinded or annulled with the written consent of the holders of a majority
in aggregate principal amount of the notes then outstanding upon the conditions
provided in the indenture. However, if an event of default is cured prior to
such declaration by the trustee or holders of the notes as discussed above, the
trustee and the holders of the notes will not be able to make such declaration
as a result of that cured event of default.

                                        21


     Overdue payments of interest, liquidated damages and premium, if any, and
principal shall accrue interest at 5.25%.

     The indenture contains a provision entitling the trustee, subject to the
duty of the trustee during default to act with the required standard of care, to
be indemnified by the holders of notes before proceeding to exercise any right
or power under the indenture at the request of such holders. The indenture
provides that the holders of a majority in aggregate principal amount of the
notes then outstanding through their written consent may direct the time, method
and place of conducting any proceeding for any remedy available to the trustee
or exercising any trust or power conferred upon the trustee.

     We are required to furnish annually to the trustee a statement as to the
fulfillment of our obligations under the indenture.

CONSOLIDATION, MERGER OR ASSUMPTION

     We may, without the consent of the holders of notes, consolidate with,
merge into or transfer all or substantially all of our assets to any other
corporation organized under the laws of the United States or any of its
political subdivisions provided that:

     - (i) Wabash shall be the surviving or continuing corporation or (ii) the
       entity or person formed by or surviving any such consolidation, merger or
       asset transfer shall be a corporation organized and validly existing
       under the laws of the United States, any State thereof or the District of
       Columbia;

     - the surviving corporation assumes all our obligations under the indenture
       and the notes pursuant to a supplemental indenture in form and substance
       reasonably satisfactory to the trustee;

     - at the time of such transaction, no event of default, and no event which,
       after notice or lapse of time, would become an event of default, shall
       have happened and be continuing; and

     - certain other conditions are met.

     Although such transactions are permitted under the indenture, certain of
the foregoing transactions occurring could constitute a change in control of
Wabash, permitting each holder to require us to purchase the notes of such
holder as described above.

MODIFICATIONS AND WAIVER

     The indenture (including the terms and conditions of the notes) may be
modified or amended by us and the trustee, without the consent of the holder of
any note, for the purposes of, among other things:

     - adding to our covenants for the benefit of the holders of notes;

     - surrendering any right or power conferred upon us;

     - providing for the assumption of our obligations to the holders of notes
       in the circumstances required under the indenture as described under
       "-- Consolidation, Merger or Assumption;"

     - reducing the conversion price, provided that the reduction will not
       adversely affect the interests of holders of notes; or

     - curing any ambiguity or correcting or supplementing any defective
       provision contained in the indenture; provided that such modification or
       amendment does not adversely affect the interests of the holders of the
       notes.

     Modifications and amendments to the indenture or to the terms and
conditions of the notes may also be made, and past default by us may be waived
with the written consent of the holders of at least a majority in aggregate
principal amount of the notes at the time outstanding. However, no such
modification, amendment or waiver may, without the written consent or the
affirmative vote of the holder of each note so affected:

     - change the maturity of the principal of or any installment of interest on
       that note (including any payment of liquidated damages);
                                        22


     - reduce the principal amount of, or any premium or interest on (including
       any payment of liquidated damages), any note;

     - change the currency of payment of such note or interest thereon;

     - impair the right to institute suit for the enforcement of any payment on
       or with respect to any note;

     - except as otherwise permitted or contemplated by provisions concerning
       corporate reorganizations, adversely affect the repurchase option of
       holders upon a Change of Control or the conversion rights of holders of
       the notes;

     - waive a default or event of default in the payment of principal of or
       interest or liquidated damages, if any, on the notes (except a rescission
       of acceleration of the notes by the holders of at least a majority in
       aggregate principal amount of the notes and a waiver of the payment
       default that resulted from such acceleration);

     - except as permitted by the indenture, increase the conversion price or
       modify the provisions of the indenture relating to conversion of the
       notes in a manner adverse to the holders; or

     - reduce the percentage in aggregate principal amount of notes outstanding
       necessary to modify or amend the indenture or to waive any past default.

FORM, DENOMINATION AND REGISTRATION

     The notes are issued in fully registered form, without coupons, in
denominations of $1,000 principal amount and whole multiples of $1,000.

     Global Notes: Book-Entry Form.  Except as provided below, the notes are
evidenced by one global note deposited with the trustee as custodian for DTC,
New York, New York, and registered in the name of Cede & Co. as DTC's nominee.
The global note and any notes issued in exchange therefor are subject to certain
restrictions on transfer set forth in the global notes and in the indenture and
bear a restrictive legend. Record ownership of the global notes may be
transferred, in whole or in part, only to another nominee of DTC or to a
successor of DTC or its nominee, except as set forth below. A Noteholder may
hold its interests in the global note directly through DTC if such noteholder is
a participant in DTC, or indirectly through organizations which are direct DTC
participants. Transfers between direct DTC participants will be effected in the
ordinary way in accordance with DTC's rules and will be settled in same-day
funds. Noteholders may also beneficially own interests in the global notes held
by DTC through certain banks, brokers, dealers, trust companies and other
parties that clear through or maintain a custodial relationship with a direct
DTC participant, either directly or indirectly. So long as Cede & Co., as
nominee of DTC, is the registered owner of the global note, Cede & Co. for all
purposes will be considered the sole holder of the global note. Except as
provided below, owners of beneficial interests in a global note will not be
entitled to have certificates registered in their names, will not receive or be
entitled to receive physical delivery of certificates in definitive form, and
will not be considered holders thereof. The laws of some states require that
certain persons take physical delivery of securities in definitive form.
Consequently, the ability to transfer a beneficial interest in a global note to
such persons may be limited. We will wire, through the facilities of the
trustee, principal, premium, if any, and interest payments on the global note to
Cede & Co., the nominee for DTC, as the registered owner of the global note. We,
the trustee and any paying agent will have no responsibility or liability for
paying amounts due on the global note to owners of beneficial interests in a
global note. It is DTC's current practice, upon receipt of any payment of
principal of and premium, if any, and interest on the global note, to credit
participants' accounts on the payment date in amounts proportionate to their
respective beneficial interests in a note represented by a global note, as shown
on the records of DTC, unless DTC believes that it will not receive payment on
the payment date. Payments by DTC participants to owners of beneficial interests
in notes represented by a global note held through DTC participants will be the
responsibility of DTC participants, as is now the case with securities held for
the accounts of customers registered in "street name."

     If you would like to convert your notes into common stock pursuant to the
terms of the notes, you should contact your broker or other direct or indirect
DTC participant to obtain information on procedures, including

                                        23


proper forms and cut-off times, for submitting those requests. Because DTC can
only act on behalf of DTC participants, who in turn act on behalf of indirect
DTC participants and other banks, your ability to pledge your interest in the
notes represented by global notes to persons or entities that do not participate
in the DTC system, or otherwise take actions in respect of such interest, may be
affected by the lack of a physical certificate. Neither we nor the trustee (nor
any registrar, paying agent or conversion agent under the indenture) will have
any responsibility for the performance by DTC or direct or indirect DTC
participants of their obligations under the rules and procedures governing their
operations. DTC has advised us that it will take any action permitted to be
taken by a holder of notes, including, without limitation, the presentation of
notes for conversion as described below, only at the direction of one or more
direct DTC participants to whose account with DTC interests in the global notes
are credited and only for the principal amount of the notes for which directions
have been given.

     DTC has advised us as follows:  DTC is a limited purpose trust company
organized under the laws of the State of New York, a member of the Federal
Reserve System, a "clearing corporation" within the meaning of the Uniform
Commercial Code and a "clearing agency" registered pursuant to the provisions of
Section 17A of the Securities Exchange Act of 1934, as amended. DTC was created
to hold securities for DTC participants and to facilitate the clearance and
settlement of securities transactions between DTC participants through
electronic book-entry changes to the accounts of its participants, thereby
eliminating the need for physical movement of certificates. Participants include
securities brokers and dealers, banks, trust companies and clearing corporations
and may include certain other organizations such as the initial purchasers.
Certain DTC participants or their representatives, together with other entities,
own DTC. Indirect access to the DTC system is available to others such as banks,
brokers, dealers and trust companies that clear through, or maintain a custodial
relationship with, a participant, either directly or indirectly. Although DTC
has agreed to the foregoing procedures in order to facilitate transfers of
interests in the global notes among DTC participants, it is under no obligation
to perform or continue to perform such procedures, and such procedures may be
discontinued at any time. If DTC is at any time unwilling or unable to continue
as depositary and a successor depositary is not appointed by us within 90 days,
we will cause notes to be issued in definitive form in exchange for the global
notes. None of us, the trustee or any of their respective agents will have any
responsibility for the performance by DTC or direct or indirect DTC participants
of their obligations under the rules and procedures governing their operations,
including maintaining, supervising or reviewing the records relating to, or
payments made on account of, beneficial ownership interests in global notes.
According to DTC, the foregoing information with respect to DTC has been
provided to its participants and other members of the financial community for
informational purposes only and is not intended to serve as a representation,
warranty or contract modification of any kind.

     Certificated notes may be issued in exchange for beneficial interests in
notes represented by the global notes only when the depositary for a global note
has notified the Company that it is unwilling or unable to continue as
depositary for such note and the Company fails to appoint a successor depositary
for such note within 90 days.

GOVERNING LAW

     The indenture and the notes are governed by, and construed in accordance
with, the law of the State of New York.

CONCERNING THE TRUSTEE

     Wachovia Bank, National Association, as trustee under the indenture, has
been appointed by us as paying agent, conversion agent, registrar and custodian
with regard to the notes. National City Bank is the transfer agent and registrar
for Wabash's common stock. The trustee or its affiliates may from time to time
in the future provide banking and other services to us in the ordinary course of
their business.

     The indenture provides that, except during the continuance of an event of
default, the trustee will perform only such duties as are specifically set forth
in the indenture. In case an event of default shall occur (and shall not be
cured) and holders of the notes have notified the trustee, the trustee will be
required to exercise its

                                        24


powers with the degree of care and skill of a prudent person in the conduct of
such person's own affairs. Subject to such provisions, the trustee is under no
obligation to exercise any of its rights or powers under the indenture at the
request of any of the holders of notes, unless they shall have offered to the
trustee security and indemnity satisfactory to it.

     The indenture contains certain limitations on the rights of the trustee,
should it become our creditor, to obtain payment of claims in certain cases or
to realize on certain property received in respect of any such claim as security
or otherwise. The trustee is permitted to engage in other transactions,
provided, however, that if it acquires any conflicting interest, it must
eliminate such conflict or resign.

REGISTRATION RIGHTS

     We agreed, at our expense, to file with the SEC this registration statement
on Form S-3 covering resales by holders of the notes and the common stock
issuable upon conversion of the notes, of which this prospectus is a part. Under
the terms of the registration rights agreement, we agreed to use our reasonable
best efforts to:

     - cause the registration statement to become effective before March 28,
       2004; and

     - keep the shelf registration statement continuously effective under the
       Securities Act until the earliest of (i) the second anniversary of the
       issue date; (ii) the date on which the notes or the common stock issuable
       upon their conversion may be sold by non-affiliates of us pursuant to
       paragraph (k) of Rule 144 (or any successor provision) promulgated by the
       SEC under the Securities Act; (iii) the date as of which all the notes or
       the common stock issuable upon their conversion have been sold under Rule
       144 under the Securities Act (or any similar provision then in force) and
       (iv) the date as of which all the notes or the common stock issuable upon
       their conversion have been sold pursuant to the shelf registration
       statement.

     We also agreed to provide to each registered holder copies of the
prospectus, notify each registered holder when the shelf registration statement
has become effective and take certain other actions as are required to permit
unrestricted resales of the notes and the common stock issuable upon conversion
of the notes. A holder who sells those securities pursuant to the shelf
registration statement generally will be required to be named as a selling
securityholder in the related prospectus and to deliver a prospectus to
purchasers and will be bound by the provisions of the registration rights
agreement, which are applicable to that holder (including certain
indemnification provisions).

     The specific provisions relating to the registration described above are
contained in the registration rights agreement which was entered into on the
closing of the initial offering of the notes.

TRANSFER AND EXCHANGE

     A holder may transfer or exchange notes in accordance with the indenture.
The registrar and the trustee may require a holder, among other things, to
furnish appropriate endorsements and transfer documents, and we may require a
holder to pay any taxes and fees required by law or permitted by the indenture.
We are not required to transfer or exchange any note for which a holder has
delivered a Change of Control repurchase notice.

     The registered holder of a note will be treated as the owner of it for all
purposes.

NO RECOURSE AGAINST OTHERS

     None of our directors, officers, employees, stockholders or affiliates, as
such, shall have any liability or any obligation under the notes or the
indenture or for any claim based on, in respect of or by reason of such
obligations or the creation of such obligations. Each holder by accepting a note
waives and releases all such liability. The waiver and release are part of the
consideration for the notes. This provision does not constitute a waiver of any
person's compliance with the federal securities laws or the Securities and
Exchange Commission's rules and regulations.

                          DESCRIPTION OF CAPITAL STOCK

     Our certificate of incorporation authorizes 100,000,000 shares of capital
stock, 75,000,000 of which are designated as common stock and 25,000,000 of
which are designated as preferred stock. The following descriptions summarize
the material terms and provisions of our authorized and outstanding capital
stock. For the complete terms of our capital stock, please refer to our
certificate of incorporation and bylaws that are filed as exhibits to our
reports incorporated by reference into this prospectus. The General Corporation
Law of Delaware, as amended, may also affect the terms of our capital stock.

COMMON STOCK


     Our certificate of incorporation provides that we have authority to issue
75,000,000 shares of our common stock, par value $.01 per share. At August 13,
2004, there were 27,325,750 shares of common stock issued and outstanding. In
addition, 1,521,474 shares of common stock were issuable upon exercise of stock
options outstanding on that date. The outstanding shares of common stock are
fully paid and nonassessable.


 VOTING RIGHTS

     Each holder of common stock is entitled to attend all special and annual
meetings of the stockholders and to vote upon any matter, including, without
limitation, the election of directors. Holders of common stock are entitled to
one vote per share.

 LIQUIDATION RIGHTS

     In the event of any dissolution, liquidation or winding up of Wabash,
whether voluntary or involuntary, the holders of common stock and holders of any
class or series of stock entitled to participate with them, will be entitled to
participate in the distribution of any assets remaining after we have paid all
of our debts and liabilities and have paid, or set aside for payment, to the
holders of any class of stock having preference over the common stock in the
event of dissolution, liquidation or winding up, the full preferential amounts,
if any, to which they are entitled.

 DIVIDENDS

     Dividends may be paid on the common stock and on any class or series of
stock entitled to participate therewith when and as declared by the board. Due
to restrictions under existing covenants in our debt agreements, we are not
permitted to pay dividends on our common stock without waiver of these
restrictions by our lenders.

 OTHER RIGHTS AND RESTRICTIONS

     The holders of common stock have no preemptive or subscription rights to
purchase additional securities issued by us, nor any rights to convert their
common stock into other securities of Wabash or to have their shares redeemed by
us. Our common stock is not subject to redemption by us. The rights, preferences
and privileges of common stockholders are subject to the rights of any series of
preferred stock that we may designate in the future. Our charter and bylaws do
not restrict the ability of a holder of common stock to transfer his or her
shares of common stock. When we issue shares of common stock upon conversion of
the notes, the shares will be fully paid and non-assessable.

                                        26


 LISTING

     Our common stock is listed on the New York Stock Exchange under the symbol
"WNC."

 TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for our common stock is National City
Bank.

 STOCKHOLDER RIGHTS PLAN

     In November 1995, our board adopted a Stockholders Rights Plan (the "Rights
Plan"). The Rights Plan is designed to deter any potential coercive or unfair
takeover tactics in the event of an unsolicited takeover attempt. It is not
intended to prevent a takeover of Wabash on terms that are favorable and fair to
all stockholders and will not interfere with a merger approved by the board of
directors. Each right entitles stockholders to buy one one-thousandth of a share
of Series A Junior Participating Preferred Stock at an exercise price of
$120.00. The rights will be exercisable only if a person or a group acquires or
announces a tender or exchange offer to acquire 20% or more of our common stock
or if we enter into other business combination transactions not approved by the
board of directors. In the event the rights become exercisable, the rights plan
allows for our stockholders to acquire stock of Wabash or the surviving
corporation, whether or not Wabash is the surviving corporation, having a value
twice that of the exercise price of the rights. The rights will expire December
28, 2005 and are redeemable for $.01 per right by our board under certain
circumstances.

 LIMITATIONS OF DIRECTOR LIABILITY

     Delaware law authorizes corporations to limit or eliminate the personal
liability of directors to corporations and their stockholders for monetary
damages for breach of directors' fiduciary duty of care. Although Delaware law
does not change directors' duty of care, it enables corporations to limit
available relief to equitable remedies such as injunction or rescission. Our
certificate of incorporation limits the liability of directors to us and our
stockholders to the full extent permitted by Delaware law. Specifically,
directors are not personally liable for monetary damages to Wabash or its
stockholders for breach of the director's fiduciary duty as a director, except
for liability for:

     - any breach of the director's duty of loyalty to Wabash or its
       stockholders;

     - acts or omissions not in good faith or that involve intentional
       misconduct or a knowing violation of law;

     - unlawful payments of dividends or unlawful stock repurchases or
       redemptions; and

     - any transaction from which the director derived an improper personal
       benefit.

 INDEMNIFICATION

     To the maximum extent permitted by law, our bylaws provide for mandatory
indemnification of directors and officers against any expense, liability or loss
to which they may become subject, or which they may incur as a result of being
or having been a director or officer. In addition, we must advance or reimburse
directors and officers for expenses they incur in connection with indemnifiable
claims.

     We also maintain directors' and officers' liability insurance.

 PREFERRED STOCK

     Our certificate of incorporation authorizes our board from time to time and
without further stockholder action, to provide for the issuance of up to
25,000,000 shares of preferred stock in one or more series, and to fix the
relative rights and preferences of the shares, including voting powers, dividend
rights, liquidation preferences, redemption rights and conversion privileges. As
of the date of this prospectus, we have classified shares of Series A Junior
Participating Preferred Stock in connection with the establishment of our
stockholder rights plan, as described above, and we have issued rights that are
in some cases exercisable for

                                        27


shares of Series A Junior Participating Preferred Stock. There are no shares of
our Preferred Stock outstanding on the date of this Prospectus.

 BLANK CHECK PREFERRED STOCK

     Our board is authorized to issue preferred stock in one or more series and
to fix and designate the rights, preferences, privileges and restrictions of the
preferred stock, including:

     - dividend rights;

     - conversion rights;

     - voting rights;

     - redemption rights and terms of redemption; and

     - liquidation preferences.

     Our board may fix the number of shares constituting any series and the
designations of these series. We have issued rights that are in some cases
exercisable for shares of our Series A Junior Participating Preferred Stock.

     The rights, preferences, privileges and restrictions of the preferred stock
of each series will be fixed by a certificate of designations relating to each
series. The certificate of designations relating to each series will specify the
terms of the preferred stock, including:

     - the maximum number of shares in the series and the distinctive
       designation;

     - the terms on which dividends will be paid, if any;

     - the terms on which the shares may be redeemed, if at all;

     - the liquidation preference, if any;

     - the terms of any retirement or sinking fund for the purchase or
       redemption of the shares of the series;

     - the terms and conditions, if any, on which the shares of the series will
       be convertible into, or exchangeable for, shares of any other class or
       classes of capital stock;

     - the voting rights, if any, on the shares of the series; and

     - any or all other preferences and relative, participating, operational or
       other special rights or qualifications, limitations or restrictions of
       the shares.

     Voting Rights.  The General Corporation Law of Delaware provides that the
holders of preferred stock will have the right to vote separately as a class on
any proposal involving fundamental changes in the rights of holders of that
preferred stock. This right is in addition to any voting rights that may be
provided for in the applicable certificate of designations.

     Other.  Our issuance of preferred stock may have the effect of delaying or
preventing a change in control. Our issuance of preferred stock could decrease
the amount of earnings and assets available for distribution to the holders of
common stock or other preferred stock or could adversely affect the rights and
powers, including voting rights, of the holders of common stock or other
preferred stock. The issuance of preferred stock could have the effect of
decreasing the market price of our common stock.

                                        28


            MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

     The following is a general discussion of certain U.S. federal income tax
considerations relevant to holders of the notes and common stock into which the
notes may be converted. This discussion is based upon the Internal Revenue Code
of 1986, as amended, which we refer to as the Code, Treasury regulations,
Internal Revenue Service, or IRS, rulings and judicial decisions now in effect,
all of which are subject to change (possibly with retroactive effect) or
different interpretations. There can be no assurance that the IRS will not
challenge one or more of the tax consequences described herein, and we have not
obtained, nor do we intend to obtain, a ruling from the IRS with respect to the
U.S. federal income tax consequences of acquiring, holding, or disposing of
notes or common stock. This discussion does not purport to deal with all aspects
of U.S. federal income taxation that may be relevant to a particular holder in
light of the holder's circumstances (for example, persons subject to the
alternative minimum tax provisions of the Code or a holder whose "functional
currency" is not the U.S. dollar). Also, it is not intended to be wholly
applicable to all categories of investors, some of which (such as dealers in
securities or currencies, traders in securities that elect to use a
mark-to-market method of accounting, banks, thrifts, regulated investment
companies, insurance companies, tax-exempt organizations and persons holding
notes or common stock as part of a hedging, conversion, constructive sale,
constructive ownership, or integrated transaction or straddle under the Code)
may be subject to special rules. The discussion also does not discuss any aspect
of state, local or foreign law or U.S. federal estate and gift tax law as
applicable to the holders of the notes and common stock into which the notes may
be converted. In addition, this discussion is limited to purchasers of notes who
are U.S. Holders (as defined below) who will hold the notes and common stock as
"capital assets" within the meaning of Section 1221 of the Code.

     ALL PROSPECTIVE PURCHASERS OF THE NOTES ARE URGED TO CONSULT THEIR OWN TAX
ADVISORS REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF THE
PURCHASE, OWNERSHIP AND DISPOSITION OF THE NOTES AND THE COMMON STOCK IN THEIR
PARTICULAR SITUATIONS.

     As used herein, the term "U.S. Holder" means a beneficial owner of a note
or common stock that for United States federal income tax purposes is (a) a
citizen or resident (as defined in Section 7701(b) of the Code) of the United
States (unless such person is not treated as a resident of the U.S. under an
applicable income tax treaty), (b) a corporation formed under the laws of the
United States or any political subdivision of the United States, (c) an estate
the income of which is subject to U.S. federal income taxation regardless of its
source or (d) in general, a trust subject to the primary supervision of a court
within the United States and the control of a United States person as described
in Section 7701(a)(30) of the Code.

     If a partnership (including for this purpose any entity, domestic or
foreign, treated as a partnership for U.S. tax purposes) is a beneficial owner
of the notes or common stock into which the notes may be converted, the U.S.
federal income tax treatment of a partner in the partnership will generally
depend on the status of the partner and the activities of the partnership. As a
general matter, income earned through a foreign or domestic partnership is
attributed to its owners. A holder of the notes or common stock into which the
notes may be converted that is a partnership and partners in such partnership
should consult their individual tax advisors about the U.S. federal income tax
consequences of holding and disposing of the notes and the common stock into
which the notes may be converted.

INTEREST/ORIGINAL ISSUE DISCOUNT

     Interest on the notes will generally be included in a U.S. Holder's gross
income as ordinary income for U.S. federal income tax purposes at the time it is
paid or accrued in accordance with the U.S. Holder's regular method of
accounting.

     In general, if the terms of a debt instrument entitle a holder to receive
payments other than fixed periodic interest that exceed the issue price of the
instrument, the holder may be required to recognize additional interest as
"original issue discount" over the term of the instrument. Furthermore, if the
amount or timing of any additional payments on a note is contingent, the note
could be subject to special rules that apply to contingent debt instruments.
These rules generally require a holder to accrue interest income at a rate
higher than the stated interest rate on the note and to treat as ordinary
income, rather than capital gain, any gain recognized on a sale, exchange or
retirement of a note before the resolution of the contingencies. In certain
                                        29


circumstances, holders of our notes could receive payments in excess of stated
principal or interest. If we do not comply with our obligations under the
registration rights agreement, such non-compliance may result in the payment of
predetermined additional amounts in the manner described in the section
"Description of the Notes -- Registration Rights." We do not believe that the
notes should be treated as contingent debt instruments because of these
potential additional payments. Therefore, for purposes of filing tax or
information returns with the IRS, we will not treat the notes as contingent debt
instruments or as having original issue discount. Our position in this regard is
binding on U.S. Holders unless they disclose their contrary position. If the
notes were treated as contingent debt instruments, the consequences described
above would apply. In the event that we pay liquidated damages, the holders
would be required to recognize additional taxable income.

MARKET DISCOUNT

     The purchasers of notes may be subject to the "market discount" provisions
of the Code. Market discount on a note will generally equal the amount, if any,
by which the principal amount of the note exceeds the holder's acquisition
price. Subject to a de minimis exception, those provisions generally require a
holder of a note acquired at a market discount to treat as ordinary income any
gain recognized on the disposition of such note to the extent of the "accrued
market discount" at the time of disposition. Market discount on a note will be
treated as accruing on a straight-line basis over the term of such note or, at
the election of the holder, under a constant-yield method. If a note with
accrued market discount that has not previously been included in gross income is
converted into common stock, the amount of such accrued market discount
generally will be taxable as ordinary income upon disposition of the common
stock received upon conversion. A holder of a note acquired at a market discount
may be required to defer the deduction of a portion of the interest on any
indebtedness incurred or maintained to purchase or carry the note until the note
is disposed of in a taxable transaction, unless the holder elects to include
market discount in income as it accrues.

PREMIUM

     If a U.S. Holder acquires a note for an amount that is greater than the
note's stated principal amount plus accrued interest, the amount of such
difference is treated as "amortizable bond premium" for U.S. Federal income tax
purposes. A U.S. Holder may elect to amortize such premium from the purchase
date to the note's maturity date under a constant-yield over the remaining term
of the note. Any such premium is not amortizable, however, to the extent it
reflects the value of the conversion privilege of the note. Amortizable bond
premium is treated as an offset to interest income on a note and not as a
separate deduction and has the effect to reducing the holder's basis in the
note. An election to amortize bond premium applies to all taxable debt
obligations held by the U.S. Holder on the first day of the first taxable year
to which such election applies or thereafter acquired by the U.S. Holder and may
not be revoked without the consent of the IRS.

CONVERSIONS OF NOTES INTO COMMON STOCK

     A U.S. Holder generally will not recognize any income, gain or loss upon
conversion of a note into common stock except with respect to cash received in
lieu of a fractional share of common stock. Cash received in lieu of a
fractional share of common stock should generally be treated as a payment in
exchange for such fractional share rather than as a dividend. Gain or loss
recognized on the receipt of cash paid in lieu of such fractional share
generally will equal the difference between the amount of cash received and the
amount of tax basis allocable to the fractional share. The adjusted tax basis of
shares of common stock received on conversion will equal the adjusted tax basis
of the note converted (reduced by the portion of adjusted tax basis allocated to
any fractional share of common stock exchanged for cash). The holding period of
such common stock received on conversion will generally include the period
during which the converted notes were held prior to conversion.

     The conversion price of the notes is subject to adjustment under certain
circumstances. Section 305 of the Code and the Treasury regulations issued
thereunder may treat the holders of the notes as having received a constructive
distribution, resulting in ordinary income (subject to a possible dividends
received deduction in the case of corporate holders) to the extent of our
current and/or accumulated earnings and profits, if, and to the extent that,
certain adjustments in the conversion price (particularly an adjustment to
reflect a taxable
                                        30


dividend to holders of common stock) increase the proportionate interests of the
holders of notes in our assets or earnings and profits, whether or not such
holder ever exercises its conversion privilege. Therefore, U.S. Holders may
recognize income in the event of a deemed distribution even though they may not
receive any cash or property. Moreover, if there is not a full adjustment to the
conversion ratio of the notes to reflect a stock dividend or other event
increasing the proportionate interest of the holders of outstanding common stock
in our assets or earnings and profits, then such increase in the proportionate
interest of the holders of the common stock generally will be treated as a
distribution to such holders, taxable as ordinary income (subject to a possible
dividends received deduction in the case of corporate holders) to the extent of
our current and/or accumulated earnings and profits. Adjustments to the
conversion price made pursuant to a bona fide reasonable adjustment formula
which has the effect of preventing dilution in the interest of the holders of
the debt instruments, however, will generally not be considered to result in a
constructive dividend distribution.

SALE, EXCHANGE OR OTHER TAXABLE DISPOSITION OF THE NOTES

     Each U.S. Holder generally will recognize gain or loss upon the sale,
exchange (other than by exercise of the conversion privilege) or other taxable
disposition of notes measured by the difference (if any) between (a) the amount
of cash and the fair market value of any property received (except to the extent
that such cash or other property is attributable to the payment of accrued
interest, which amount will be taxable as ordinary income to the extent not
previously included in gross income of the holder) and (b) such holder's
adjusted tax basis in the notes. A U.S. Holder's adjusted tax basis in a note
generally will equal the holder's cost of the note, increased by any market
discount previously included in income by the U.S. Holder and reduced (but not
below zero) by any amortizable bond premium that the U.S. Holder has taken into
account. Any such gain or loss recognized on the sale, exchange or other taxable
disposition of a note (except to the extent of any accrued and unrecognized
market discount, which will be taxable as ordinary income) generally will be
capital gain or loss and will be long-term capital gain or loss if the note has
been held for more than 12 months at the time of the sale or exchange. Certain
U.S. Holders (including individuals) are eligible for preferential U.S. federal
income tax rates in respect of long-term capital gains. The deductibility of
capital losses is subject to certain limitations under the Code.

     If, upon a change of control, a holder requires us to repurchase some or
all of the holder's notes and we elect to pay the repurchase price in shares of
our common stock, the redemption may qualify as a recapitalization for U.S.
federal income tax purposes if the notes qualify as "securities" for those
purposes. Although debt instruments with a term of five years or less, such as
the notes, generally are not considered "securities," the matter is not free
from doubt. If the redemption qualifies as a recapitalization, a U.S. Holder
would not recognize any income, gain or loss on the holder's receipt of our
common stock in exchange for notes, except to the extent the stock received is
attributable to accrued interest. If the holder receives cash in lieu of
fractional shares of stock, however, the holder would be treated as if he
received the fractional share and then had the fractional share redeemed for
cash. The holder would recognize gain or loss equal to the difference between
the cash received and that portion of his basis in the stock attributable to the
fractional share. The holder's aggregate basis in the stock (including any
fractional share for which cash is paid) would equal his adjusted basis in the
note. The holder's holding period for the stock would include the period during
which he held the note. If the redemption does not qualify as a
recapitalization, a U.S. Holder will generally recognize capital gain or loss
equal to the difference between the amount realized by the U.S. Holder and the
U.S. Holder's adjusted tax basis in the note as described above.

OWNERSHIP AND DISPOSITION OF COMMON STOCK

     Distributions, if any, paid on the common stock, to the extent made from
our current and/or accumulated earnings and profits, as determined under U.S.
federal income tax principles, will be included in a U.S. Holder's gross income
as ordinary income (subject to a possible dividends received deduction in the
case of corporate holders) when received. In the case of a non-corporate U.S.
Holder, such dividend income will generally be taxable at a reduced rate in any
taxable year beginning before January 1, 2009. To the extent, if any, that a
U.S. Holder receives distributions on shares of common stock that would
otherwise constitute dividends for U.S. federal income tax purposes but that
exceed our current and accumulated earnings and

                                        31


profits, such distributions will be treated first as a non-taxable return of
capital, reducing the U.S. Holder's basis in the shares of common stock. Any
distribution in excess of the U.S. Holder's basis in the shares of common stock
generally will be treated as capital gains. Gain or loss realized on the sale,
exchange or other taxable disposition of common stock will equal the difference
between the amount realized on such sale, exchange or other taxable disposition
and the U.S. Holder's adjusted tax basis in such common stock. Subject to the
discussion under "Market Discount" above, such gain or loss generally will be
capital gain or loss, and will be long-term capital gain or loss if the U.S.
Holder has held the common stock for more than twelve months. Certain U.S.
Holders (including individuals) are eligible for preferential U.S. federal
income tax rates in respect of long-term capital gains. The deductibility of
capital losses is subject to certain limitations under the Code.

INFORMATION REPORTING AND BACKUP WITHHOLDING

     A U.S. Holder of notes or common stock may be subject to "backup
withholding" at a rate currently of 28% with respect to certain "reportable
payments," including interest payments, dividend payments, proceeds from the
disposition of the notes or common stock to or through a broker and, under
certain circumstances, principal payments of the notes. These backup withholding
rules apply if the U.S. Holder, among other things, (a) fails to furnish a
social security number or other taxpayer identification number, or TIN,
certified under penalties of perjury within a reasonable time after the request
therefor, (b) fails to report properly interest or dividends, (c) under certain
circumstances, fails to provide a certified statement, signed under penalties of
perjury, that the TIN furnished is the correct number and that such holder is
not subject to backup withholding or if (d) the IRS provides notification that
the U.S. Holder has furnished us with an incorrect TIN. Any amount withheld from
a payment to a U.S. Holder under the backup withholding rules is creditable
against the U.S. Holder's U.S. federal income tax liability, provided that the
required information is furnished to the IRS. Backup withholding will not apply,
however, with respect to payments made to certain U.S. Holders, including
corporations and tax exempt organizations, provided their exemptions from backup
withholding are properly established.

     We will report to the U.S. Holders of notes and common stock and to the IRS
the amount of our "reportable payments" for each calendar year and the amount of
tax withheld, if any, with respect to such payments.

     The preceding discussion of certain U.S. federal income tax consequences is
intended for general information only and does not constitute tax advice.
Accordingly, each investor should consult its own tax adviser as to particular
tax consequences to it of purchasing, holding and disposing of the notes and the
common stock, including the applicability and effect of any state, local or
foreign tax laws, and of any proposed changes in applicable laws.

                                 LEGAL MATTERS

     Hogan & Hartson L.L.P., Baltimore, Maryland has passed upon certain legal
matters in connection with the notes and the common stock.

                                    EXPERTS

     Ernst & Young LLP, independent auditors, have audited our consolidated
financial statements included in our Annual report on Form 10-K, as amended, for

     On May 30, 2002, we appointed Ernst & Young as our independent public
accountants to audit our financial statements for fiscal year 2002. The decision
to change auditors was not the result of any disagreement between Arthur
Andersen and us on any matter of accounting principle or practice, financial
statement disclosure or auditing scope or procedure. For a discussion of certain
risks associated with Arthur Andersen's audit of our consolidated financial
statements, see the section of this prospectus entitled "Risk Factors -- Risks
Related to an Investment in the Notes and Common Stock."

ITEM 15.          INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Section 145 of the Delaware General Corporation Law authorizes a court
to award, or a corporation's board of directors to grant, indemnity to directors
and officers under some circumstances for liabilities incurred in connection
with their activities in such capacities (including reimbursement for expenses
incurred). Article TENTH of the Company's Certificate of Incorporation provides
that it will indemnify its directors and officers to the fullest extent
permitted by law and that directors shall not be liable for monetary damages to
the Company or its stockholders for breach of fiduciary duty, except to the
extent not permitted under Delaware General Corporation Law. In addition, the
Company's Amended and Restated Bylaws provide that any director or officer who
was or is a party or is threatened to be made a party to any action or
proceeding by reason of his or her services to the Company will be indemnified
to the fullest extent permitted by the Delaware General Corporation Law.

ITEM 17.          UNDERTAKINGS

         (a)      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. Notwithstanding the foregoing, any increase or decrease in volume of
securities offered (if the total dollar value of securities offered would not
exceed that which was registered) and any deviation from the low or high end of
the estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than a 20% change in the maximum
aggregate offering price set forth in the "Calculation of Registration Fee"
table in the effective 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.

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

         (2)      That, for the purpose of determining any liability under the
Securities Act, 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 that 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.

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

         (c)      Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act of 1933 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.

                                      II-2


                                   SIGNATURES


         Pursuant to the requirements of the Securities Act of 1933, the
registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-3 and has duly caused this registration
statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of Lafayette, State of Indiana, on August 17, 2004.
