(continued from prior page)
 
     Certain specific terms of the particular Securities in respect of which
this Prospectus is being delivered are set forth in an accompanying prospectus
supplement (the "Prospectus Supplement"), including, where applicable: (i) in
the case of Stock Purchase Contracts, the number of shares of Common Stock
issuable thereunder, the purchase price of the Common Stock, the date or dates
on which the Common Stock is required to be purchased by the holders of the
Stock Purchase Contracts, any periodic payments required to be made by the
Company to the holders of the Stock Purchase Contracts or vice versa, and the
terms of the offering and sale thereof; (ii) in the case of Stock Purchase
Units, the specific terms of the Stock Purchase Contracts and any Preferred
Securities or debt obligations of third parties securing the holder's obligation
to purchase the Common Stock under the Stock Purchase Contracts, and the terms
of the offering and sale thereof; (iii) in the case of the Debentures or Debt
Securities, the specific designation, aggregate principal amount, denominations,
maturity, interest payment dates, interest rate (which may be fixed or variable)
or method of calculating interest, if any, applicable Extension Period (as
defined below) or interest deferral terms, if any, place or places where
principal, premium, if any, and interest, if any, will be payable, any terms of
redemption, any sinking fund provisions, terms for any conversion or exchange
into other securities, initial offering or purchase price, methods of
distribution and any other special terms; (iv) in the case of Preferred
Securities, the specific title, aggregate amount, stated liquidation preference,
number of securities, the rate of payment of periodic cash distributions
("Distributions") or method of calculating such rate, applicable Extension
Period or Distribution deferral terms, if any, place or places where
Distributions will be payable, any terms of redemption, initial offering or
purchase price, methods of distribution and any other special terms; and (v) in
the case of Common Stock, the number of shares offered, the methods of
distribution and the public offering or purchase price. If so specified in the
applicable Prospectus Supplement, the Securities offered thereby may be issued
in whole or in part in the form of one or more temporary or permanent global
securities ("Global Securities").
 
     The Debentures and Debt Securities will be unsecured. Unless otherwise
specified in a Prospectus Supplement, the Debentures and Debt Securities will be
senior unsecured obligations of the Company and will rank pari passu in right of
payment with all of the Company's other senior unsecured obligations. If
provided in an accompanying Prospectus Supplement, the Company will have the
right to defer payments of interest on any series of Debentures by extending the
interest payment period thereon at any time or from time to time for such number
of consecutive interest payment periods (which shall not extend beyond the
maturity of the Debentures) with respect to each deferral period as may be
specified in such Prospectus Supplement (each, an "Extension Period"). See
"Description of Debentures--Option to Defer Interest Payments". The Debentures
and Debt Securities may be denominated in U.S. Dollars, or at the option of
Kennametal, to the extent described herein and in the applicable Prospectus
Supplement, in one or more foreign currencies or currency units.
 
     The Company will be the owner of the common securities (the "Common
Securities," and, together with the Preferred Securities, the "Trust
Securities") of the Trust. The payment of Distributions with respect to the
Preferred Securities and payments on liquidation or redemption with respect to
the Preferred Securities, in each case out of funds held by the Trust, will be
irrevocably guaranteed by the Company to the extent described herein (the
"Guarantee"). Certain payments in respect of the Common Securities may also be
guaranteed by the Company. See "Description of the Guarantee." Unless otherwise
specified in a Prospectus Supplement, the obligations of the Company under the
Guarantee will be senior unsecured obligations of the Company and will rank pari
passu with all of the Company's other senior unsecured obligations. Concurrently
with the issuance by the Trust of the Preferred Securities, the Trust will
invest the proceeds thereof and any contributions made in respect of the Common
Securities in the Debentures, which will have terms corresponding to the terms
of the Preferred Securities. The Debentures will be the sole assets of the
Trust, and payments under the Debentures and those made by the Company in
respect of fees and expenses incurred by the Trust will be the only revenues of
the Trust. Upon the occurrence of certain events as are described herein and in
the accompanying Prospectus Supplement, the Company may redeem the Debentures
and cause the redemption of the Trust Securities. In addition, if provided in
the applicable Prospectus Supplement, the Company may dissolve the Trust at any
time and, after satisfaction of the liabilities to creditors of the Trust as
provided by applicable law, cause the Debentures to be distributed to the
holders of the Preferred Securities in liquidation of their interests in the
Trust.

<PAGE>   6
 
See "Description of Preferred Securities--Redemption--Distribution of
Debentures" and "--Liquidation Distribution Upon Dissolution."
 
     Holders of the Preferred Securities will be entitled to receive
preferential cumulative cash Distributions accruing from the date of original
issuance and payable periodically as specified in an accompanying Prospectus
Supplement. If provided in an accompanying Prospectus Supplement, the Company
will have the right to defer payments of interest on the Debentures by extending
the interest payment period thereon at any time or from time to time for one or
more Extension Periods (which shall not extend beyond the maturity of the
Debentures). If interest payments are so deferred, Distributions on the
Preferred Securities will also be deferred and the Company will not be
permitted, subject to certain exceptions set forth herein, to declare or pay any
cash distributions with respect to the Company's capital stock or debt
securities that rank pari passu with or junior to the Debentures. During an
Extension Period, Distributions will continue to accumulate (and the Preferred
Securities will accumulate additional Distributions thereon at the rate per
annum if and as specified in the related Prospectus Supplement). See
"Description of Preferred Securities--Distributions."
 
     Taken together, the Company's obligations under the Debentures, the
Indenture (as defined herein), the Declaration (as defined herein) and the
Guarantee, in the aggregate, have the effect of providing a full, irrevocable
and unconditional guarantee of payments of Distributions and other amounts due
on the Preferred Securities. See "Relationship Among the Preferred Securities,
the Debentures and the Guarantee."

                                   THE TRUST
 
     The Trust is a statutory business trust created under the laws of the State
of Delaware pursuant to (i) a declaration of trust, dated as of November   ,
1997, executed by the Company, as sponsor (the "Sponsor") and certain of the
trustees of the Trust (the "Kennametal Trustees") and (ii) the filing of a
certificate of trust with the Secretary of State of the State of Delaware on
November 12, 1997. Such declaration will be amended and restated in its entirety
substantially in the form filed as an exhibit to the Registration Statement of
which this Prospectus forms a part. The Declaration will be qualified as an
indenture under the Trust Indenture Act of 1939, as amended (the "Trust
Indenture Act"). The Company will directly or indirectly acquire Common
Securities in an aggregate liquidation amount equal to 3% of the total capital
of the Trust. The Trust exists for the exclusive purposes of (i) issuing the
Trust Securities representing undivided beneficial interests in the assets of
the Trust, (ii) investing the proceeds of the Trust Securities in the Debentures
and (iii) engaging in only those other activities necessary or incidental
thereto unless otherwise specified in the applicable Prospectus Supplement. The
Trust has a term of approximately seven (7) years, but may dissolve earlier as
provided in the Declaration.
 
     Pursuant to the Declaration, the number of Kennametal Trustees initially is
five. Three of the Kennametal Trustees (the "Regular Trustees") are persons who
are employees or officers of or who are affiliated with the Company. Pursuant to
the Declaration, the fourth trustee will be a financial institution that is
unaffiliated with the Company, which trustee serves as institutional trustee
under the Declaration and as indenture trustee for the purposes of compliance
with the provisions of the Trust Indenture Act (the "Institutional Trustee").
For the purpose of compliance with the provisions of the Trust Indenture Act,
the Institutional Trustee will also act as trustee (the "Guarantee Trustee")
under the Guarantee and as the trustee in the State of Delaware (the "Delaware
Trustee") for the purposes of the Trust Act (as defined herein), until removed
or replaced by the holder of the Common Securities. See "Description of the
Guarantee" and "Description of Preferred Securities--Voting Rights; Amendment of
Declaration."
 
     The Institutional Trustee will hold title to the Debentures for the benefit
of the holders of the Trust Securities and the Institutional Trustee will have
the power to exercise all rights, powers and privileges under the Indenture as
the holder of the Debentures. In addition, the Institutional Trustee will
maintain exclusive control of a segregated non-interest bearing bank account
(the "Property Account") to hold all payments made in respect of the Debentures
for the benefit of the holders of the Trust Securities. The Institutional
Trustee will make payments of distributions and payments on liquidation,
redemption and otherwise to the holders of the Trust Securities out of funds
from the Property Account. The Guarantee Trustee will hold the Guarantee for the
benefit of the holders of the Preferred Securities. The Company, as the direct
or indirect holder of all the Common Securities, will have the right to appoint,
remove or replace any Kennametal Trustee and to increase or decrease the number
of

at least three, a majority of which shall be Regular Trustees. The Company will
pay all fees and expenses related to the Trust and the offering of the Trust
Securities. See "Description of the Guarantee--Expenses of the Trust."
 
     The rights of the holders of the Preferred Securities, including economic
rights, rights to information and voting rights, are set forth in the
Declaration, the Delaware Business Trust Act, as amended (the "Trust Act"), and
the Trust Indenture Act. See "Description of the Preferred Securities."

                                USE OF PROCEEDS
 
     Unless otherwise specified in the applicable Prospectus Supplement,
Kennametal intends to apply the net proceeds from the sale of the Securities
(including Debentures issued to the Trust in connection with the investment by
the Trust of all of the proceeds from the sale of the Preferred Securities) to
which this Prospectus relates to its general funds to be used for general
corporate purposes including capital expenditures, acquisitions, the reduction
of indebtedness and other purposes. Funds not required immediately for such
purposes may be invested in short-term obligations or used to reduce the future
level of the Company's indebtedness.

Trustee"). This summary of certain terms and provisions of the Debentures and
the Indenture is not necessarily complete, and reference is hereby made to the

to in this Section or in a Prospectus Supplement, such defined terms are
incorporated herein or therein by reference.

series of Debentures will be issued as senior unsecured debt under the Indenture

senior unsecured obligations. See "Subordination." Except as otherwise provided
in the applicable Prospectus Supplement, the Indenture does not limit the
incurrence or issuance of other secured or unsecured debt of the Company,

<PAGE>   12
 
     If any index is used to determine the amount of payments of principal,
premium, if any, or interest on any series of Debentures, certain material U.S.
federal income tax, accounting and other considerations applicable thereto will
be described in the applicable Prospectus Supplement.
 
DENOMINATIONS, REGISTRATION AND TRANSFER
 
     Unless otherwise specified in the applicable Prospectus Supplement, the
Debentures will be issuable only in registered form without coupons in
denominations of $1,000 and any integral multiple thereof. Debentures of any
series will be exchangeable for other Debentures of the same issue and series,
of any authorized denominations of a like aggregate principal amount, the same
original issue date ("Original Issue Date"), stated maturity ("Stated Maturity")
and bearing the same interest rate.
 
     Debentures may be presented for exchange as provided above, and may be
presented for registration of transfer (with the form of transfer endorsed
thereon, or a satisfactory written instrument of transfer, duly executed), at
the office of the appropriate Securities Registrar or at the office of any
transfer agent designated by the Company for such purpose with respect to any
series of Debentures and referred to in the applicable Prospectus Supplement,
without service charge and upon payment of any taxes and other governmental
charges as described in the Indenture. The Company will appoint the Debt Trustee
as Securities Registrar under the Indenture. If the applicable Prospectus
Supplement refers to any transfer agents (in addition to the Securities
Registrar) initially designated by the Company with respect to any series of
Debentures, the Company may at any time rescind the designation of any such
transfer agent or approve a change in the location through which any such
transfer agent acts, provided that the Company maintains a transfer agent in
each Place of Payment for such series. The Company may at any time designate
additional transfer agents with respect to any series of Debentures.
 
     In the event of any redemption, neither the Company nor the Debt Trustee
shall be required to (i) issue, register the transfer of or exchange Debentures
of any series during a period beginning at the opening of business 15 days
before the day of selection for redemption of Debentures of that series, and
ending at the close of business on the day of mailing of the relevant notice of
redemption or (ii) transfer or exchange any Debentures so selected for
redemption, except, in the case of any Debentures being redeemed in part, any
portion thereof not to be redeemed.
 
GLOBAL DEBENTURES
 
     Unless otherwise specified in the applicable Prospectus Supplement, the
Debentures of a series may be issued in whole or in part in the form of one or
more Global Debentures that will be deposited with, or on behalf of, a
depositary identified in the Prospectus Supplement relating to such series.
Global Debentures may be issued only in fully registered form and in either
temporary or permanent form. Unless and until it is exchanged in whole or in
part for the individual Debentures represented thereby, a Global Debenture may
not be transferred except as a whole by the depositary for such Global Debenture
to a nominee of such depositary or by a nominee of such depositary to such
depositary or another nominee of such depositary or by the depositary or any
nominee to a successor depositary or any nominee of such successor.
 
     The specific terms of the depositary arrangement with respect to a series
of Debentures will be described in the Prospectus Supplement relating to such
series. The Company anticipates that the following provisions will generally
apply to depositary arrangements.
 
     Upon the issuance of a Global Debenture, and the deposit of such Global
Debenture with or on behalf of the applicable depositary, the depositary for
such Global Debenture or its nominee will credit on its book-entry registration
and transfer system, the respective principal amounts of the individual
Debentures represented by such Global Debenture to the accounts of persons that
have accounts with such depositary ("Participants"). Such accounts shall be
designated by the dealers, underwriters or agents with respect to such
Debentures or by the Company if such Debentures are offered and sold directly by
the Company. Ownership of beneficial interests in a Global Debenture will be
limited to participants or persons that may hold interests through Participants.
Ownership of beneficial interests in such Global Debenture will be shown on, and
the transfer of that ownership will be effected only through, records maintained
by the applicable depositary or its nominee (with respect to
 
                                        9
<PAGE>   13
 
interests of Participants) and the records of Participants (with respect to
interests of persons who hold through Participants). The laws of some states
require that certain purchasers of securities take physical delivery of such
securities in definitive form. Such limits and such laws may impair the ability
to transfer beneficial interests in a Global Debenture.
 
     So long as the depositary for a Global Debenture, or its nominee, is the
registered owner of such Global Debenture, such depositary or such nominee, as
the case may be, will be considered the sole owner or holder of the Debentures
represented by such Global Debenture for all purposes under the Indenture.
Except as provided below, owners of beneficial interests in a Global Debenture
will not be entitled to have any of the individual Debentures of the series
represented by such Global Debenture registered in their names, will not receive
or be entitled to receive physical delivery of any such Debentures of such
series in definitive form and will not be considered the owners or holders
thereof under the Indenture.
 
     Payments of principal of (and premium, if any) and interest on individual
Debentures represented by a Global Debenture registered in the name of a
depositary or its nominee will be made to such depositary or its nominee, as the
case may be, as the registered owner of the Global Debenture representing such
Debentures. None of the Company, the Debt Trustee, any paying agent, or the
Securities Registrar for such Debentures will have any responsibility or
liability for any aspect of the records relating to or payments made on account
of beneficial ownership interest of the Global Debenture for such Debentures or
for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests.
 
     The Company expects that the depositary for a series of Debentures or its
nominee, upon receipt of any payment of principal, premium or interest in
respect of a permanent Global Debenture representing any of such Debentures,
immediately will credit Participants' accounts with payments in amounts
proportionate to their respective beneficial interest in the principal amount of
such Global Debenture for such Debentures as shown on the records of such
depositary or its nominee. The Company also expects that payments by
Participants to owners of beneficial interests in such Global Debenture held
through such Participants will be governed by standing instructions and
customary practices, as is now the case with securities held for the accounts of
customers in bearer form or registered in "street name." Such payments will be
the responsibility of such Participants.
 
     Unless otherwise specified in the applicable Prospectus Supplement, if the
depositary for a series of Debentures is at any time unwilling, unable or
ineligible to continue as depositary and a successor depositary is not appointed
by the Company within 90 days, the Company will issue individual Debentures of
such series in exchange for the Global Debenture representing such series of
Debentures. In addition, unless otherwise specified in the applicable Prospectus
Supplement, the Company may at any time and in its sole discretion, subject to
any limitations described in the Prospectus Supplement relating to such
Debentures, determine not to have any Debentures of such series represented by
one or more Global Debentures and, in such event, will issue individual
Debentures of such series in exchange for such Global Debentures. Further, if
the Company so specifies with respect to the Debentures of a series, an owner of
a beneficial interest in a Global Debenture representing Debentures of such
series may, on terms acceptable to the Company, the Debt Trustee and the
depositary for such Global Debenture, receive individual Debentures of such
series in exchange for such beneficial interests, subject to any limitations
described in the Prospectus Supplement relating to such Debentures. In any such
instance, an owner of a beneficial interest in a Global Debenture will be
entitled to physical delivery of individual Debentures of the series represented
by such Global Debenture equal in principal amount to such beneficial interest
and to have such Debentures registered in its name. Individual Debentures of
such series so issued will be issued in denominations, unless otherwise
specified by the Company, of $1,000 and integral multiples thereof. The
applicable Prospectus Supplement may specify other circumstances under which
individual Debentures may be issued in exchange for the Global Debenture
representing any Debentures.
 
PAYMENT AND PAYING AGENTS
 
     Unless otherwise indicated in the applicable Prospectus Supplement, payment
of principal of (and premium, if any) and any interest on Debentures will be
made at the office of the Debt Trustee in Delaware or at the office of such
paying agent or paying agents as the Company may designate from time to time in
the applicable Prospectus Supplement, except that at the option of the Company
payment of any interest may be made (i) except
 
                                       10
<PAGE>   14
 
in the case of Global Debentures, by check mailed to the address of the person
or entity entitled thereto as such address shall appear in the Securities
Register or (ii) by transfer to an account maintained by the person or entity
entitled thereto as specified in the Securities Register, provided that proper
transfer instructions have been received by the Regular Record Date. Unless
otherwise indicated in the applicable Prospectus Supplement, payment of any
interest on Debentures will be made to the person or entity in whose name such
Debenture is registered at the close of business on the Regular Record Date for
such interest, except in the case of defaulted interest ("Defaulted Interest").
The Company may at any time designate additional paying agents or rescind the
designation of any paying agent; however, the Company will at all times be
required to maintain a paying agent in each Place of Payment for each series of
Debentures.
 
     Any moneys deposited with the Debt Trustee or any paying agent, or held by
the Company in trust, for the payment of the principal of (and premium, if any)
or interest on any Debenture and remaining unclaimed for two years after such
principal (and premium, if any) or interest has become due and payable shall, at
the request of the Company, be repaid to the Company or released from such
trust, as applicable, and the holder of such Debenture shall thereafter look, as
a general unsecured creditor, only to the Company for payment thereof.
 
REDEMPTION
 
     Unless otherwise indicated in the applicable Prospectus Supplement,
Debentures will not be subject to any sinking fund.
 
     Unless otherwise indicated in the applicable Prospectus Supplement, the
Company may, at its option, redeem the Debentures of any series in whole at any
time or in part from time to time, at the redemption price set forth in the
applicable Prospectus Supplement plus accrued and unpaid interest to the date
fixed for redemption, and Debentures in denominations larger than $50 may be
redeemed in part but only in integral multiples of $50. If the Debentures of any
series are so redeemable only on or after a specified date or upon the
satisfaction of additional conditions, the applicable Prospectus Supplement will
specify such date or describe such conditions.
 
     Except as otherwise specified in the applicable Prospectus Supplement, if a
Special Event (as defined in "Description of Preferred
Securities--Redemption--Special Event Redemption" below or in the applicable
Prospectus Supplement) in respect of the Trust shall occur and be continuing,
the Company may, at its option, redeem such series of Debentures, in whole (but
not in part), at a redemption price equal to the amount described in the
applicable Prospectus Supplement. See "Description of Preferred
Securities--Redemption--Special Event Redemption."
 
     Notice of any redemption will be mailed at least 30 days but not more than
60 days before the redemption date to each holder of Debentures to be redeemed
at such holder's registered address. Unless the Company defaults in the payment
of the redemption price, on and after the redemption date interest shall cease
to accrue on such Debentures or portions thereof called for redemption.
 
OPTION TO DEFER INTEREST PAYMENTS
 
     If provided in the applicable Prospectus Supplement, the Company shall have
the right, at any time and from time to time during the term of any series of
Debentures, to defer the payment of interest for such number of consecutive
interest payment periods as may be specified in the applicable Prospectus
Supplement (each, an "Extension Period"), subject to the terms, conditions and
covenants, if any, specified in such Prospectus Supplement, provided that such
Extension Period may not extend beyond the Stated Maturity of the Debentures.
Certain material U.S. federal income tax consequences and special considerations
applicable to any such Debentures will be described in the applicable Prospectus
Supplement.
 
     At the end of such Extension Period, the Company shall pay all interest
then accrued and unpaid together with interest thereon compounded semiannually
at the rate specified for the Debentures to the extent permitted by applicable
law ("Compound Interest"); provided, that during any such Extension Period, (a)
the Company shall not declare or pay dividends on, make any distribution with
respect to, or redeem, purchase, acquire or make a liquidation payment with
respect to, any of its capital stock (other than (i) purchases or acquisitions
of capital stock of the Company in connection with the satisfaction by the
Company of its obligations under any employee
 
                                       11
<PAGE>   15
 
benefit plans or the satisfaction by the Company of its obligations pursuant to
any contract or security outstanding on the date of such event requiring the
Company to purchase capital stock of the Company, (ii) as a result of a
reclassification of the Company's capital stock or the exchange or conversion of
one class or series of the Company's capital stock for another class or series
of the Company's capital stock, (iii) the purchase of fractional interests in
shares of the Company's capital stock pursuant to the conversion or exchange
provisions of such capital stock or the security being converted or exchanged,
(iv) dividends or distributions in capital stock of the Company and (v)
redemptions or purchases of any rights pursuant to the Rights Agreement, as
amended, between the Company and Mellon Bank, N.A., as Rights Agent (the "Rights
Agreement"), or any successor to the Rights Agreement, and the declaration
thereunder of a dividend of rights in the future, (b) the Company shall not make
any payment of interest, principal or premium, if any, on or repay, repurchase
or redeem any debt securities issued by the Company that rank pari passu with or
junior to the Debentures, and (c) the Company shall not make any guarantee
payments with respect to the foregoing (other than payments pursuant to the
Guarantee or the Common Securities Guarantee). Prior to the termination of any
such Extension Period, the Company may further defer payments of interest by
extending the interest payment period; provided, however, that, such Extension
Period, including all such previous and further extensions, may not extend
beyond the maturity of the Debentures. Upon the termination of any Extension
Period and the payment of all amounts then due, the Company may commence a new
Extension Period, subject to the terms set forth in this section. No interest
during an Extension Period, except at the end thereof, shall be due and payable,
but the Company may prepay at any time all or any portion of the interest
accrued during an Extension Period. The Company has no present intention of
exercising its right to defer payments of interest by extending the interest
payment period on the Debentures. If the Institutional Trustee shall be the sole
holder of the Debentures, the Company shall give the Regular Trustees and the
Institutional Trustee notice of its selection of such Extension Period one
Business Day prior to the earlier of (i) the date distributions on the Preferred
Securities are payable or (ii) the date the Regular Trustees are required to
give notice to the New York Stock Exchange (or other applicable self-regulatory
organization) or to holders of the Preferred Securities of the record or payment
date of such distribution. The Regular Trustees shall give notice of the
Company's selection of such Extension Period to the holders of the Preferred
Securities. If the Institutional Trustee shall not be the sole holder of the
Debentures, the Company shall give the holders of the Debentures notice of its
selection of such Extension Period ten Business Days prior to the earlier of (i)
the Interest Payment Date or (ii) the date upon which the Company is required to
give notice to the New York Stock Exchange (or other applicable self-regulatory
organization) or to holders of the Debentures of the record or payment date of
such related interest payment.
 
MODIFICATION OF INDENTURE
 
     From time to time, the Indenture may be modified by the Company and the
Debt Trustee without the consent of any holders of the Debentures with respect
to certain matters, including (i) to cure any ambiguity, defect or inconsistency
or to correct or supplement any provision which may be inconsistent with any
other provision of the Indenture, (ii) to qualify, or maintain the qualification
of, the Indenture under the Trust Indenture Act and (iii) to make any change
that does not materially adversely affect the interests of any holder of
Debentures. In addition, under the Indenture, certain rights and obligations of
the Company and the rights of holders of the Debentures may be modified by the
Company and the Debt Trustee with the written consent of the holders of at least
a majority in aggregate principal amount of the outstanding Debentures; but no
extension of the maturity of the Debentures, reduction in the interest rate or
extension of the time for payment of interest, change in the optional redemption
or repurchase provisions in a manner adverse to any holder of Debentures, other
modification in the terms of payment of the principal of, or interest on, the
Debentures, or reduction of the percentage required for modification, will be
effective against any holder of any outstanding Debentures without the holder's
consent.
 
     In addition, the Company and the Debt Trustee may execute, without the
consent of any holder of the Debentures, any supplemental Indenture for the
purpose of creating any new series of Debentures.

INDENTURE EVENTS OF DEFAULT
 
     The Indenture provides that any one or more of the following described
events with respect to a series of Debentures that has occurred and is
continuing constitutes an "Indenture Event of Default" with respect to such
series of Debentures:
 
     (i) failure for 30 days to pay any interest on such series of the
Debentures when due (subject to the deferral of any due date in the case of an
Extension Period); or
 
     (ii) failure to pay any principal or premium, if any, on such series of the
Debentures when due whether at maturity, upon redemption, by declaration or
otherwise; or
 
     (iii) failure to observe or perform in any material respect certain other
covenants contained in the Indenture for 90 days after written notice has been
given to the Company from the Debt Trustee or the holders of at least 25% in
principal amount of such series of outstanding Debentures; or
 
     (iv) certain events in bankruptcy, insolvency or reorganization of the
Company.
 
     The holders of a majority in outstanding principal amount of such series of
Debentures have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Debt Trustee. The Debt Trustee or the
holders of not less than 25% in aggregate outstanding principal amount of such
series of Debentures may declare the principal due and payable immediately upon
an Indenture Event of Default. The holders of a majority in aggregate
outstanding principal amount of such series of Debentures may annul such
declaration and waive the default if the default (other than the non-payment of
the principal of such series of Debentures which has become due solely by such
acceleration) has been cured and a sum sufficient to pay all matured
installments of interest and principal due otherwise than by acceleration has
been deposited with the Debt Trustee.
 
     The holders of a majority in outstanding principal amount of the Debentures
affected thereby may, on behalf of the holders of all the Debentures, waive any
past default, except a default in the payment of principal or interest (unless
such default has been cured and a sum sufficient to pay all matured installments
of interest and principal due otherwise than by acceleration has been deposited
with the Debt Trustee) or a default in respect of a covenant or provision which
under the Indenture cannot be modified or amended without the consent of the
holder of each outstanding Debenture. The Company is required to file annually
with the Debt Trustee a certificate as to whether or not the Company is in
compliance with all the conditions and covenants applicable to it under the
Indenture.
 
     In case an Indenture Event of Default shall occur and be continuing as to a
series of Debentures, all of which are held by the Trust, the Institutional
Trustee will have the right to declare the principal of and the interest on such
Debentures, and any other amounts payable under the Indenture, to be forthwith
due and payable and to enforce its other rights as a creditor with respect to
such Debentures.
 
ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF PREFERRED SECURITIES
 
     If an Indenture Event of Default with respect to the Debentures has
occurred and is continuing and such event is attributable to the failure of the
Company to pay interest or principal on the Debentures on the date such interest
or principal is otherwise payable, a holder of the Preferred Securities may
institute a legal proceeding directly against the Company for enforcement of
payment to such holder of the principal of or interest on such Debentures having
a principal amount equal to the aggregate liquidation amount of the Preferred
Securities of such holder (a "Direct Action"). The Company may not amend the
Indenture to remove the foregoing right to bring a Direct Action without the
prior written consent of the holders of all of the Preferred Securities. If the
right to bring a Direct Action is removed, the Trust may become subject to the
reporting obligations under the Exchange Act. Unless otherwise specified in the
applicable Prospectus Supplement, the Company shall have the right under the
Indenture to set-off any payment made to such holder of Preferred Securities by
the Company in connection with a Direct Action. The holders of Preferred
Securities will not be able to exercise directly any other remedy available to
the holders of the Debentures unless there shall have been an Event of Default
under the Declaration. See "Description of Preferred Securities--Events of
Default; Notice."

<PAGE>   17
 
CONSOLIDATION, MERGER, SALE OF ASSETS AND OTHER TRANSACTIONS
 
     The Indenture provides that the Company shall not consolidate with or merge
into any other person or entity or sell, assign, convey, transfer or lease its
properties and assets substantially as an entirety to any person or entity
unless (i) either the Company is the continuing corporation, or any successor or
purchaser is a corporation, partnership, or trust or other entity organized
under the laws of the United States of America, any State thereof or the
District of Columbia, and any such successor or purchaser expressly assumes the
Company's obligations on the Debentures under a supplemental indenture; and (ii)
immediately after giving effect thereto, no Indenture Event of Default, and no
event which, after notice or lapse of time or both, would become an Indenture
Event of Default, shall have happened and be continuing.
 
     The general provisions of the Indenture do not afford holders of the
Debentures protection in the event of a highly leveraged or other transaction
involving the Company that may adversely affect holders of the Debentures.
 
SATISFACTION AND DISCHARGE; DEFEASANCE
 
     The Indenture provides that when, among other things, all Debentures not
previously delivered to the Debt Trustee for cancellation (i) have become due
and payable or (ii) will become due and payable at their Stated Maturity within
one year, and the Company deposits or causes to be deposited with the Debt
Trustee, as trust funds in trust for the purpose, an amount in the currency or
currencies in which the Debentures are payable sufficient to pay and discharge
the entire indebtedness on the Debentures not previously delivered to the Debt
Trustee for cancellation, for the principal (and premium, if any) and interest
to the date of the deposit or to the Stated Maturity, as the case may be, then
the Indenture will cease to be of further effect (except as to the Company's
obligations to pay all other sums due pursuant to the Indenture and to provide
the officers' certificates and opinions of counsel described therein), and the
Company will be deemed to have satisfied and discharged the Indenture. The
Company will also have the right to defease the Debentures if and to the extent
indicated in the applicable Prospectus Supplement.
 
CONVERSION OR EXCHANGE
 
     If and to the extent indicated in the applicable Prospectus Supplement, the
Debentures of any series may be convertible or exchangeable into Preferred
Securities or other securities. The specific terms on which Debentures of any
series may be so converted or exchanged will be set forth in the applicable
Prospectus Supplement. Such terms may include provisions for conversion or
exchange, either mandatory, at the option of the holder, or at the option of the
Company, in which case the number of shares of Preferred Securities or other
securities to be received by the holders of Debentures would be calculated as of
a time and in the manner stated in the applicable Prospectus Supplement.
 
GOVERNING LAW
 
     The Indenture and the Debentures will be governed by and construed in
accordance with the laws of the State of New York.
 
MISCELLANEOUS
 
     The Company will pay all fees and expenses related to (i) the offering of
the Trust Securities and the Debentures, (ii) the organization, maintenance and
dissolution of the Trust, (iii) the retention of the Kennametal Trustees and
(iv) the enforcement by the Institutional Trustee of the rights of the holders
of the Preferred Securities.
 
INFORMATION CONCERNING THE DEBT TRUSTEE
 
     The Debt Trustee shall have and be subject to all the duties and
responsibilities specified with respect to an indenture trustee under the Trust
Indenture Act. Subject to such provisions, the Debt Trustee is under no
obligation to exercise any of the powers vested in it by the Indenture at the
request of any holder of the Debentures, unless offered reasonable indemnity by
such holder against the costs, expenses and liabilities which
 
                                       14
<PAGE>   18
 
might be incurred thereby. The Debt Trustee is not required to expend or risk
its own funds or otherwise incur personal financial liability in the performance
of its duties if the Debt Trustee reasonably believes that repayment or adequate
indemnity is not reasonably assured to it.
 
               , the Debt Trustee, is also Institutional Trustee and Delaware
Trustee under the Declaration and Guarantee Trustee under the Guarantee. The
Company maintains trust and other business relationships in the ordinary course
of business with           . Pursuant to the provisions of the Trust Indenture
Act, upon the occurrence of certain events,           may be deemed to have a
conflicting interest, by virtue of its acting as the Institutional Trustee, the
Delaware Trustee, the Debt Trustee and the Guarantee Trustee, and its other
business relationships with the Company, and thereby may be required to resign
and be replaced by a successor trustee under the Indenture, the Declaration and
the Guarantee.

                         DESCRIPTION OF DEBT SECURITIES
 
     The following description sets forth certain general terms and provisions
of the Debt Securities to which any Prospectus Supplement may relate. The
particular terms and provisions of the series of Debt Securities offered by a
Prospectus Supplement, and the extent to which such general terms and provisions
described below may apply thereto, will be described in the Prospectus
Supplement relating to such series of Debt Securities.
 
     The Debt Securities are to be issued under an Indenture, dated as of
               , 1997, between Kennametal and                , as Trustee (the
"Trustee"). The following summaries of certain provisions of the Debt Securities
and the Indenture do not purport to be complete and are subject to, and are
qualified by reference to, all provisions of the Debt Securities and the
Indenture, including the definitions therein of certain terms. Wherever
particular sections or defined terms of the Indenture are referred to, it is
intended that such sections or defined terms shall be incorporated herein by
reference.
 
GENERAL
 
     The Indenture does not limit the aggregate principal amount of Debt
Securities that can be issued thereunder, and Debt Securities may be issued
thereunder up to the aggregate principal amount which may be authorized from
time to time by, or pursuant to a resolution of, Kennametal's Board of Directors
or by a supplemental indenture. Reference is made to the applicable Prospectus
Supplement for the following terms of the particular series of Debt Securities
being offered hereby: (i) the title of the Debt Securities of the series; (ii)
any limit upon the aggregate principal amount of the Debt Securities of the
series; (iii) the date or dates on which the principal of the Debt Securities of
the series will mature; (iv) the rate or rates (or manner of calculations
thereof), if any, at which the Debt Securities of the series will bear interest,
the date or dates from which any such interest will accrue and on which such
interest will be payable, and, with respect to Debt Securities of the series in
registered form, the record date for the interest payable on any interest
payment date; (v) the place or places where the principal of and interest, if
any, on the Debt Securities of the series will be payable; (vi) any redemption
or sinking fund provisions; (vii) if other than the entire principal amount
thereof, the portion of the principal amount of Debt Securities of the series
which will be payable upon declaration of acceleration of the maturity thereof;
(viii) whether the Debt Securities of the series will be issuable in registered
or bearer form or both, any restrictions applicable to the offer, sale or
delivery of Debt Securities in bearer form ("bearer Debt Securities"), and
whether, and the terms upon which, bearer Debt Securities will be exchangeable
for Debt Securities in registered form ("registered Debt Securities") and vice
versa; (ix) whether and under what circumstances Kennametal will pay additional
amounts on the Debt Securities of the series held by a person who is not a U.S.
person (as defined below) in respect of taxes or similar charges withheld or
deducted and, if so, whether Kennametal will have the option to redeem such Debt
Securities rather than pay such additional amounts; (x) whether the Debt
Securities will be denominated or provide for payment in United States dollars
or a foreign currency or units of two or more such foreign currencies; (xi)
whether the Debt Securities of the series will be convertible into or
exchangeable or exercisable for shares of a class of capital stock of Kennametal
or any other corporation and the terms and conditions relating thereto; and
(xii) any additional provisions or other special terms not inconsistent with the
provisions of the Indenture, including any terms which may be required by or
advisable under United States laws or regulations or advisable in connection
with the marketing of Debt Securities of such series. To the extent not
described herein, principal, premium, if any, and interest will be payable, and
the Debt Securities of a particular series will be transferable, in the manner
described in the Prospectus Supplement relating to such series.
 
     Unless otherwise specified in a Prospectus Supplement, each series of Debt
Securities will constitute senior indebtedness of Kennametal and will rank on a
parity with Kennametal's other senior indebtedness.
 
     Debt Securities of any series may be issued as registered Debt Securities
or bearer Debt Securities or both, as specified in the terms of the series.
Unless otherwise indicated in the applicable Prospectus Supplement, Debt
Securities will be issued in denominations of $1,000 and integral multiples
thereof, and bearer Debt Securities will not be offered, sold, resold or
delivered to U.S. persons in connection with their original issuance. For
purposes of this Prospectus, "U.S. person" means a citizen, national or resident
of the United States, a corporation, partnership or other entity created or
organized in or under the laws of the United States or any
 
                                       16
<PAGE>   20
 
political subdivision thereof, or an estate or trust which is subject to United
States federal income taxation regardless of its source of income.
 
     To the extent set forth in the Prospectus Supplement, except in special
circumstances set forth in the Indenture, interest on bearer Debt Securities
will be payable only against presentation and surrender of the coupons for the
interest installments evidenced thereby as they mature at a paying agency of
Kennametal located outside of the United States and its possessions. Kennametal
will maintain such an agency for a period of two years after the principal of
such bearer Debt Securities has become due and payable. During any period
thereafter for which it is necessary in order to conform to United States tax
law or regulations, Kennametal will maintain a paying agent outside the United
States and its possessions to which the bearer Debt Securities may be presented
for payment and will provide the necessary funds therefor to such paying agent
upon reasonable notice.
 
     The general provisions of the Indenture do not afford holders of the Debt
Securities protection in the event of a highly leveraged transaction,
reorganization, merger or similar transaction involving Kennametal that may
adversely affect holders of the Debt Securities.
 
     Bearer Debt Securities and the coupons related thereto will be transferable
by delivery.
 
     If appropriate, federal income tax consequences applicable to a series of
Debt Securities will be described in the Prospectus Supplement relating thereto.
 
GLOBAL SECURITIES
 
     The Debt Securities of a series may be issued in the form of one or more
fully registered global securities (each a "Global Security") that will be
deposited with, or on behalf of, a depositary (the "Depositary") identified in
the Prospectus Supplement relating to such series. Unless and until it is
exchanged for Debt Securities in definitive registered form, a Global Security
may not be transferred except as a whole by the Depositary for such Global
Security to a nominee of such Depositary or by a nominee of such Depositary to
such Depositary or another nominee of such Depositary or by such Depositary or
any such nominee to a successor of such Depositary or a nominee of such
successor.
 
     The specific terms of the depositary arrangements with respect to a series
of Debt Securities will be described in the Prospectus Supplement relating to
such series. Kennametal anticipates that the following provisions will apply to
all depositary arrangements.
 
     Upon the issuance of a Global Security, the Depositary for such Global
Security will credit the accounts held with it with the respective principal
amounts of the Debt Securities represented by such Global Security. Such
accounts shall be designated by the underwriters or agents with respect to such
Debt Securities or by Kennametal if such Debt Securities are offered and sold
directly by Kennametal. Ownership of beneficial interests in a Global Security
will be limited to persons that have accounts with the Depositary for such
Global Security ("participants") or persons that may hold interests through
participants. Ownership of beneficial interests in such Global Security will be
shown on, and the transfer of that ownership will be effected only through,
records maintained by the Depositary for such Global Security or on the records
of participants. The laws of some states require that certain purchasers of
securities take physical delivery of such securities in definitive form. Such
limits and such laws may impair the ability to transfer beneficial interests in
a Global Security.
 
     So long as the Depositary for a Global Security, or its nominee, is the
registered owner of such Global Security, such Depositary or such nominee, as
the case may be, will be considered the sole owner or holder of the Debt
Securities represented by such Global Security for all purposes under the
Indenture governing such Debt Securities. Except as provided below, owners of
beneficial interests in a Global Security will not be entitled to have Debt
Securities of the series represented by such Global Security registered in their
names, will not receive or be entitled to receive physical delivery of Debt
Securities of such series in definitive form and will not be considered the
owners or holders thereof under the Indenture governing such Debt Securities.
 
     Principal, premium, if any, and interest payments on Debt Securities
registered in the name of a Depositary or its nominee will be made to the
Depositary or its nominee, as the case may be, as the registered owner of the
 
                                       17
<PAGE>   21
 
Global Security representing such Debt Securities. Neither Kennametal, the
Trustee for such Debt Securities, any Paying Agent nor the Security Registrar
for such Debt Securities will have any responsibility or liability for any
aspect of the records relating to or payments made on account of beneficial
ownership interests in the Global Security for such Debt Securities or for
maintaining, supervising or reviewing any records relating to such beneficial
ownership interests.
 
     Kennametal expects that the Depositary for a series of Debt Securities
issued in the form of a Global Security, upon receipt of any payment of
principal, premium, if any, or interest, will credit immediately participants'
accounts with payments in amounts proportionate to their respective beneficial
interests in the principal amount of the Global Security for such Debt
Securities as shown on the records of such Depositary. Kennametal also expects
that payments by participants to owners of beneficial interests in such Global
Security held through such participants will be governed by standing
instructions and customary practices, as is now the case with securities held
for the accounts of customers in bearer form or registered in "street name," and
will be the responsibility of such participants.
 
     If a Depositary for a series of Debt Securities is at any time unwilling or
unable to continue as depositary and a successor depositary is not appointed by
Kennametal within 90 days, Kennametal will issue Debt Securities of such series
in definitive form in exchange for the Global Security representing such series
of Debt Securities. In addition, Kennametal may at any time and in its sole
discretion determine not to have the Debt Securities of a series represented by
a Global Security and, in such event, will issue Debt Securities of such series
in definitive form in exchange for the Global Security representing such series
of Debt Securities. In either instance, an owner of a beneficial interest in a
Global Security will be entitled to have Debt Securities of the series
represented by such Global Security equal in principal amount to such beneficial
interest registered in its name and will be entitled to physical delivery of
such Debt Securities in definitive form. Debt Securities of such series so
issued in definitive form will be issued in denominations of $1,000 and integral
multiples thereof and will be issued in registered form only, without coupons.
 
EXCHANGE OF SECURITIES
 
     To the extent permitted by the terms of a series of Debt Securities
authorized to be issued in registered form and bearer form, bearer Debt
Securities may be exchanged for an equal aggregate principal amount of
registered Debt Securities of the same series and date of maturity in such
authorized denominations as may be requested upon surrender of the bearer Debt
Securities with all unpaid coupons relating thereto, at an agency of Kennametal
maintained for such purpose and upon fulfillment of all other requirements of
such agent. As of the date of this Prospectus, United States Treasury
regulations do not permit exchanges of registered Debt Securities for bearer
Debt Securities and unless such regulations are modified, the terms of a series
of Debt Securities will not permit registered Debt Securities to be exchanged
for bearer Debt Securities.
 
AMENDMENT AND WAIVER
 
     Subject to certain exceptions, the Indenture may be amended or supplemented
by Kennametal and the Trustee with the consent of the holders (the "Debt
Securityholders") of a majority in principal amount of the outstanding Debt
Securities of each series affected by the amendment or supplement (with each
series voting as a class), or compliance with any provision may be waived with
the consent of the holders of a majority in principal amount of the outstanding
Debt Securities of each series affected by such waiver (with each series voting
as a class). However, without the consent of each Debt Securityholder affected,
an amendment or waiver may not (i) reduce the amount of Debt Securities whose
holders must consent to an amendment or waiver; (ii) change the rate of or
change the time for payment of interest on any Debt Security; (iii) change the
principal of or change the fixed maturity of any Debt Security; (iv) change the
terms of any Debt Securities so as to adversely affect the terms on which such
Debt Securities are convertible into, or exchangeable or exercisable for, shares
of a class of capital stock of Kennametal or any other corporation; (v) waive a
default in the payment of the principal of or interest on any Debt Security;
(vi) make any Debt Security payable in money other than that stated in the Debt
Security; or (vii) impair the right to institute suit for the enforcement of any
payment on or with respect to any Debt Security. The Indenture may be amended or
supplemented without the consent of any Debt Securityholder (i) to cure any
ambiguity, defect or inconsistency in the Indenture or the Debt Securities of
any series; (ii) to
 
                                       18
<PAGE>   22
 
provide for the assumption of all the obligations of Kennametal under the Debt
Securities, any coupons related thereto and the Indenture by any corporation in
connection with a merger, consolidation, transfer or lease of Kennametal's
property and assets substantially as an entirety, as provided for in the
Indenture; (iii) to provide for uncertificated Debt Securities in addition to or
in place of certificated Debt Securities; (iv) to make any change that does not
adversely affect the rights of any Debt Securityholder; (v) to provide for the
issuance of and establish the form and terms and conditions of a series of Debt
Securities endorsed thereon or to establish the form of any certifications
required to be furnished pursuant to the terms of the Indenture or any series of
Debt Securities; or (vi) to add to the rights of Debt Securityholders.
 
MERGER
 
     Kennametal may consolidate with or merge into, or transfer or lease its
property and assets substantially as an entirety to, another entity if the
successor entity is a corporation and assumes all the obligations of Kennametal
under the Debt Securities and any coupons related thereto and the Indenture and
if, after giving effect to such transaction, a Default or Event of Default would
not occur or be continuing. Thereafter, all such obligations of Kennametal shall
terminate.
 
EVENTS OF DEFAULT
 
     The following events are defined in the Indenture as "Events of Default"
with respect to a series of Debt Securities: (i) default in the payment of
interest on any Debt Security of such series for 90 days; (ii) default in the
payment of the principal of any Debt Security of such series; (iii) failure by
Kennametal for 90 days after notice to it to comply with any of its other
agreements in the Debt Securities of such series, in the Indenture or in any
supplemental indenture; and (iv) certain events of bankruptcy or insolvency of
Kennametal. If an Event of Default occurs with respect to the Debt Securities of
any series and is continuing, the Trustee or the holders of at least 25% in
principal amount of all of the outstanding Debt Securities of that series may
declare the principal (or, if the Debt Securities of that series are original
issue discount Debt Securities, such portion of the principal amount as may be
specified in the terms of that series) of all the Debt Securities of that series
to be due and payable. Upon such declaration, such principal (or, in the case of
original issue discount Debt Securities, such specified amount) shall be due and
payable immediately.
 
     Debt Securityholders may not enforce the Indenture or the Debt Securities
except as provided in the Indenture. The Trustee may require indemnity
satisfactory to it before it enforces the Indenture or the Debt Securities.
Subject to certain limitations, holders of a majority in principal amount of the
Debt Securities of each series affected (with each series voting as a class) may
direct the Trustee in its exercise of any trust power. The Trustee may withhold
from holders of Debt Securities notice of any continuing default (except a
default in payment of principal or interest) if it determines that withholding
notice is in their interests.
 
CONCERNING THE TRUSTEE
 
     Kennametal and certain of its affiliates maintain banking relationships in
the ordinary course of business with the Trustee. In addition, the Trustee and
certain of its affiliates serve as trustee, authenticating agent or paying agent
with respect to certain debt securities of Kennametal and its affiliates.

                      DESCRIPTION OF PREFERRED SECURITIES
 
     Pursuant to the terms of the Declaration, the Kennametal Trustees on behalf
of the Trust will issue the Preferred Securities and the Common Securities. The
Preferred Securities will represent preferred undivided beneficial interests in
the assets of the Trust and the holders thereof will be entitled to a preference
in certain circumstances with respect to Distributions and amounts payable on
redemption or liquidation over the Common Securities, as well as other benefits
as described in the Declaration. This summary of certain provisions of the
Preferred Securities and the Declaration is not necessarily complete, and
reference is hereby made to the copy of the Declaration, including the
definitions therein of certain terms, which is filed as an exhibit to the
Registration Statement of which this Prospectus forms a part, and to the Trust
Indenture Act. Wherever particular defined terms of the Declaration are referred
to in this Section or in a Prospectus Supplement, such defined terms are
incorporated herein by reference.
 
GENERAL
 
     The Preferred Securities of the Trust will rank pari passu, and payments
will be made thereon pro rata, with the Common Securities of the Trust except as
described under "Subordination of Common Securities." Legal title to the
Debentures will be held by the Institutional Trustee in trust for the benefit of
the holders of the Preferred Securities and Common Securities. The Guarantee
Agreement executed by the Company for the benefit of the holders of the Trust's
Preferred Securities (the "Guarantee") will be a guarantee on a subordinated
basis with respect to the Preferred Securities but will not guarantee payment of
Distributions or amounts payable on redemption or liquidation of the Preferred
Securities when the Trust does not have funds on hand available to make such
payments. See "Description of the Guarantee."
 
DISTRIBUTIONS
 
     The Trust's Preferred Securities represent preferred undivided beneficial
interests in the assets of the Trust, and the Distributions on each Preferred
Security will be payable at a rate specified in the Prospectus Supplement for
the Preferred Securities. The amount of Distributions payable for any period
will be computed on the basis of a 360-day year of twelve 30-day months unless
otherwise specified in the applicable Prospectus Supplement. Distributions that
are in arrears will accumulate additional Distributions thereon at the rate per
annum if and as specified in the applicable Prospectus Supplement ("Additional
Amounts"). The term "Distributions" as used herein includes any Additional
Amounts unless otherwise stated.
 
     Distributions on the Preferred Securities will be cumulative, will
accumulate from the date of original issuance and will be payable on such dates
as specified in the applicable Prospectus Supplement. In the event that any date
on which Distributions are payable on the Preferred Securities is not a Business
Day (as defined below), payment of the Distribution payable on such date will be
made on the next succeeding day that is a Business Day (and without any interest
or other payment in respect of any such delay) except that, if such Business Day
is in the next succeeding calendar year, payment of such Distribution shall be
made on the immediately preceding Business Day, in each case with the same force
and effect as if made on such date (each date on which Distributions are payable
in accordance with the foregoing, a "Distribution Date"). A "Business Day" shall
mean any day other than a Saturday or a Sunday, or a day on which banking
institutions in The City of New York are authorized or required by law or
executive order to remain closed or a day on which the corporate trust office of
the Institutional Trustee or the Debt Trustee is closed for business.
 
     If provided in the applicable Prospectus Supplement, the Company has the
right under the Indenture to defer payments of interest on the Debentures by
extending the interest payment period thereon from time to time for a period or
periods that will be specified in the applicable Prospectus Supplement. Such
extension right, if exercised, would result in the deferral of Distributions on
the Preferred Securities (though such Distributions would continue to accumulate
additional Distributions thereon at the rate per annum if and as specified in
the applicable Prospectus Supplement) during any such extended interest payment
period. Such right to extend the interest payment period for the Debentures is
limited to a period not extending beyond the Stated Maturity of the Debentures.
In the event that the Company exercises this right, then (a) the Company shall
not declare or pay dividends on, make distributions with respect to, or redeem,
purchase or acquire, or make a liquidation payment
 
                                       20
<PAGE>   24
 
with respect to, any of its capital stock other than (i) purchases or
acquisitions of capital stock (of the Company in connection with the
satisfaction by the Company of its obligations under any employee benefit plans
or the satisfaction by the Company of its obligations pursuant to any contract
or security outstanding on the date of such event requiring the Company to
purchase capital stock of the Company, (ii) as a result of a reclassification of
the Company's capital stock or the exchange or conversion of one class or a
series of the Company's capital stock for another class or a series of the
Company's capital stock, (iii) the purchase of fractional interests in shares of
the Company's capital stock pursuant to the conversion or exchange provisions of
such capital stock or the security being converted or exchanged, (iv) dividends
or distributions in capital stock of the Company and (v) redemptions or
purchases of any rights pursuant to the Rights Agreement, and the declaration
thereunder of a dividend of rights in the future), (b) the Company shall not
make any payment of interest, principal or premium, if any, on or repay,
repurchase or redeem any debt securities issued by the Company that rank pari
passu with or junior to the Debentures, and (c) the Company shall not make any
guarantee payments with respect to the foregoing (other than payments pursuant
to the Guarantee or the Common Securities Guarantee (as defined herein)). Prior
to the termination of any such Extension Period, the Company may further extend
the interest payment period; provided, that such Extension Period, together with
all such previous and further extensions thereof, may not extend beyond the
Stated Maturity of the Debentures. Upon the termination of any Extension Period
and the payment of all amounts then due, the Company may select a new Extension
Period, subject to the above requirements. See "Description of the
Debentures--Option to Defer Interest Payments." If Distributions are deferred,
the deferred Distributions and accumulated additional Distributions thereon
shall be paid to holders of record of the Preferred Securities as they appear on
the books and records of the Trust on the record date next following the
termination of such deferral period.
 
     It is anticipated that the revenue of the Trust available for distribution
to holders of its Preferred Securities will be limited to payments under the
Debentures in which the Trust will invest the proceeds from the issuance and
sale of the Preferred Securities and the Common Securities. See "Description of
Debentures--Debentures." If the Company does not make interest payments on such
Debentures, the Institutional Trustee will not have funds available to pay
Distributions on the Preferred Securities. The payment of Distributions (if and
to the extent the Trust has funds legally available for the payment of such
Distributions and cash sufficient to make such payments) is guaranteed by the
Company on a limited basis as set forth herein under "Description of the
Guarantee."
 
     Distributions on the Preferred Securities will be payable to the holders
thereof as they appear on the register of the Trust on the relevant record
dates, which, as long as the Preferred Securities remain in book-entry form,
will be one Business Day prior to the relevant Distribution Date. Subject to any
applicable laws and regulations and the provisions of the Declaration, unless
otherwise specified in the applicable Prospectus Supplement, each such payment
will be made as described under "Book-Entry Issuance." In the event any
Preferred Securities are not in book-entry form, the relevant record date for
such Preferred Securities shall be the date, at least 15 days prior to the
relevant Distribution Date, that is specified in the applicable Prospectus
Supplement.
 
REDEMPTION
 
     MANDATORY REDEMPTION.  Unless otherwise specified in the applicable
Prospectus Supplement, upon any repayment, redemption, in whole or in part, of
any Debentures that are held by the Trust unless otherwise specified in the
applicable Prospectus Supplement, whether at maturity or upon earlier redemption
as provided in the Indenture, the proceeds from such repayment or redemption
shall be applied by the Institutional Trustee to redeem a Like Amount (as
defined below) of the related Trust Securities, upon not less than 30 nor more
than 60 days notice, at a redemption price (the "Redemption Price") equal to the
aggregate liquidation amount of such Trust Securities plus accumulated and
unpaid Distributions thereon to the date of redemption (the "Redemption Date")
and the related amount of the premium, if any, paid by the Company upon the
concurrent redemption of such Debentures. See "Description of
Debentures--Optional Redemption." If less than all of any series of Debentures
that are held by the Trust are to be repaid or redeemed on a Redemption Date,
then the proceeds from such repayment or redemption shall be allocated to the
redemption pro rata of the Preferred Securities and the Common Securities. The
amount of premium, if any, paid by the Company upon the redemption of all or any
part
 
                                       21
<PAGE>   25
 
of any Debentures held by the Trust shall be allocated pro rata to the Preferred
Securities and the Common Securities.
 
     DISTRIBUTION OF DEBENTURES.  Unless otherwise specified in the applicable
Prospectus Supplement, the Company will have the right at any time to dissolve
the Trust and, after satisfaction of the liabilities of creditors of the Trust
as provided by applicable law, to cause the Debentures in respect of the Trust
Securities issued by the Trust to be distributed to the holders of the Trust
Securities in liquidation of the Trust.
 
     After the liquidation date fixed for any distribution of Debentures held by
the Trust, (i) the Preferred Securities will no longer be deemed to be
outstanding, (ii) the depositary (if any) for the Preferred Securities, as the
record holder of the Preferred Securities, will receive a registered global
certificate or certificates representing the Debentures to be delivered upon
such distribution and (iii) any certificates representing such Preferred
Securities not held by or on behalf of such depositary will be deemed to
represent the Debentures having a principal amount equal to the liquidation
amount of the Preferred Securities, and bearing accrued and unpaid interest in
an amount equal to the accrued and unpaid Distributions on the Preferred
Securities, until such certificates are presented to the Regular Trustees or
their agent for transfer or reissuance.
 
     There can be no assurance as to the market prices for the Preferred
Securities or the Debentures that may be distributed in exchange for Preferred
Securities if a dissolution or liquidation of the Trust were to occur.
Accordingly, the Preferred Securities that an investor may purchase, or the
Debentures that the investor may receive on dissolution or liquidation of the
Trust, may trade at a discount to the price that the investor paid to purchase
the Preferred Securities offered hereby.
 
     SPECIAL EVENT REDEMPTION.  If a Tax Event or an Investment Company Event
(each as defined below or in the applicable Prospectus Supplement, a "Special
Event") shall occur and be continuing, unless otherwise specified in the
applicable Prospectus Supplement, the Company will have the right to redeem the
Debentures in whole (but not in part) and therefore cause a mandatory redemption
of the Trust Securities in whole (but not in part) at the Redemption Price
within 90 days following the occurrence of such Special Event.
 
     If provided in the applicable Prospectus Supplement, the Company shall have
the right to extend or shorten the maturity of any series of Debentures held by
the Trust at the time that the Company exercises its right to elect to dissolve
the Trust and, after satisfaction of the liability to creditors of the Trust as
provided by applicable law, cause such Debentures to be distributed to the
holders of the Preferred Securities and Common Securities of the Trust in
liquidation of the Trust, provided that it can extend the maturity only if
certain conditions specified in the applicable Prospectus Supplement are met at
the time such election is made and at the time of such extension.
 
     "Tax Event" means the receipt by the Trust of an opinion of counsel
experienced in such matters to the effect that, as a result of (i) any amendment
to, or change (including any announced prospective change) in, the laws (or any
regulations thereunder) of the United States or any political subdivision or
taxing authority thereof or therein affecting taxation, (ii) any amendment to or
change in an interpretation or application of such laws or regulations by any
legislative body, court, governmental agency or regulatory authority or (iii)
any interpretation or pronouncement that provides for a position with respect to
such laws or regulations that differs from the generally accepted position on
the date the Preferred Securities are issued, which amendment or change is
effective or which interpretation or pronouncement is announced on or after the
date of issuance of the Preferred Securities under the Declaration, there is
more than an insubstantial risk that (x) the Trust is, or will be within 90 days
of the date thereof, subject to U.S. federal income tax with respect to income
received or accrued on the Debentures, (y) interest payable by the Company on
the Debentures is not, or within 90 days of the date thereof, will not be,
deductible, in whole or in part, for U.S. federal income tax purposes, or (z)
the Trust is, or will be within 90 days of the date thereof, subject to more
than a de minimis amount of other taxes, duties or other governmental charges.
 
     "Investment Company Event" means the occurrence of a change in law or
regulation or a change in interpretation or application of law or regulation by
any legislative body, court, governmental agency or regulatory authority (a
"Change in 1940 Act Law") to the effect that the Trust is or will be considered
an "investment company" that is required to be registered under the Investment
Company Act of 1940, as amended
 
                                       22
<PAGE>   26
 
(the "Investment Company Act"), which Change in 1940 Act Law becomes effective
on or after the date of original issuance of the Preferred Securities.
 
     "Like Amount" means (i) with respect to a redemption of any Trust
Securities, Trust Securities having a liquidation amount equal to that portion
of the principal amount of Debentures to be contemporaneously redeemed in
accordance with the Indenture, allocated to the Common Securities and to the
Preferred Securities based upon the relative liquidation amounts of such classes
of Trust Securities, and the proceeds of which will be used to pay the
Redemption Price of such Trust Securities, and (ii) with respect to a
distribution of Debentures to holders of any Trust Securities in connection with
a dissolution or liquidation of Trust, Debentures having a principal amount
equal to the liquidation amount of the Trust Securities of the holder to whom
such Debentures are distributed.
 
REDEMPTION PROCEDURES
 
     Preferred Securities redeemed on each Redemption Date shall be redeemed at
the Redemption Price with the applicable proceeds from the contemporaneous
redemption of the Debentures. Redemptions of Preferred Securities shall be made
and the Redemption Price shall be payable on each Redemption Date only to the
extent that the Trust has funds on hand available for the payment of such
Redemption Price. See also "--Subordination of Common Securities."
 
     If the Trust gives a notice of redemption in respect of the Preferred
Securities, then, on the Redemption Date, to the extent funds are available, the
Institutional Trustee will deposit irrevocably with the Depositary for the
Preferred Securities (if such Preferred Securities are issued in the form of one
or more Global Preferred Securities) funds sufficient to pay the applicable
Redemption Price and will give such Depositary irrevocable instructions and
authority to pay the Redemption Price to the beneficial owners of the Preferred
Securities. See "--Global Preferred Securities" and "Book-Entry Issuance." If
the Preferred Securities are not issued in the form of one or more Global
Preferred Securities, the Trust, to the extent funds are available, will
irrevocably deposit with the paying agent for the Preferred Securities funds
sufficient to pay the applicable Redemption Price and will give such paying
agent irrevocable instructions and authority to pay the Redemption Price to the
holders thereof upon surrender of their certificates evidencing the Preferred
Securities. Notwithstanding the foregoing, Distributions payable on or prior to
the Redemption Date for the Preferred Securities called for redemption shall be
payable to the holders of the Preferred Securities on the relevant record dates
for the related Distribution Dates. If a notice of redemption shall have been
given and funds deposited as required, then upon the date of such deposit, all
rights of the holders of the Preferred Securities so called for redemption will
cease, except the right of the holders of the Preferred Securities to receive
the Redemption Price, but without interest on such Redemption Price, and the
Preferred Securities will cease to be outstanding. In the event that any date
fixed for redemption of Preferred Securities is not a Business Day, then payment
of the Redemption Price payable on such date will be made on the next succeeding
day which is a Business Day (and without any interest or other payment in
respect of any such delay), except that, if such Business Day falls in the next
calendar year, such payment will be made on the immediately preceding Business
Day. In the event that payment of the Redemption Price in respect of Preferred
Securities called for redemption is improperly withheld or refused and not paid
either by the Trust or by the Company pursuant to the Guarantee as described
under "Description of the Guarantee", Distributions on such Preferred Securities
will continue to accumulate at the then applicable rate, from the Redemption
Date originally established by the Trust for the Preferred Securities to the
date such Redemption Price is actually paid, in which case the actual payment
date will be the date fixed for redemption for purposes of calculating the
Redemption Price.
 
     Subject to applicable law (including, without limitation, U.S. federal
securities law), the Company or its subsidiaries may at any time and from time
to time purchase outstanding Preferred Securities by tender, in the open market
or by private agreement.
 
     If less than all of the Preferred Securities and Common Securities issued
by the Trust are to be redeemed on a Redemption Date, then the aggregate
liquidation amount of such Preferred Securities and Common Securities to be
redeemed shall be allocated pro rata among the Preferred Securities and Common
Securities of such Trust based on the relative liquidation amounts of such
classes of Trust Securities. The particular Preferred Securities to
 
                                       23
<PAGE>   27
 
be redeemed shall be selected on a pro rata basis not more than 60 days prior to
the Redemption Date by the Institutional Trustee from the outstanding Preferred
Securities not previously called for redemption, by such method as the
Institutional Trustee shall deem fair and appropriate and which may provide for
the selection for redemption of portions (equal to $50 or an integral multiple
of $50 in excess thereof) of the liquidation amount of Preferred Securities of a
denomination larger than $50. The Institutional Trustee shall promptly notify
the registrar in writing of the Preferred Securities selected for redemption
and, in the case of any Preferred Securities selected for partial redemption,
the liquidation amount thereof to be redeemed. For all purposes of each
Declaration, unless the context otherwise requires, all provisions relating to
the redemption of Preferred Securities shall relate, in case of any Preferred
Securities redeemed or to be redeemed only in part, to the portion of the
aggregate liquidation amount of Preferred Securities which has been or is to be
redeemed.
 
     Notice of any redemption will be mailed at least 30 days but not more than
60 days before the Redemption Date to each holder of Preferred Securities to be
redeemed at its registered address. Unless the Company defaults in payment of
the Redemption Price on the Debentures, on and after the Redemption Date
interest will cease to accrue on the Debentures or portions thereof (and
Distributions will cease to accumulate on the Preferred Securities or portions
thereof) called for redemption.
 
SUBORDINATION OF COMMON SECURITIES
 
     Payment of Distributions (including Additional Amounts, if applicable) on,
and the Redemption Price of, the Trust's Preferred Securities and Common
Securities, as applicable, shall be made pro rata based on the liquidation
amount of the Preferred Securities and Common Securities; provided, however,
that if on any Distribution Date or Redemption Date, an Indenture Event of
Default shall have occurred and be continuing, no payment of any Distribution
(including Additional Amounts, if applicable) on, or Redemption Price of, any of
the Trust's Common Securities, and no other payment on account of the
redemption, liquidation or other acquisition of such Common Securities, shall be
made unless payment in full in cash of all accumulated and unpaid Distributions
(including Additional Amounts, if applicable) on all of the Trust's outstanding
Preferred Securities for all Distribution periods terminating on or prior
thereto, or in the case of payment of the Redemption Price the full amount of
such Redemption Price on all of the Trust's outstanding Preferred Securities
then called for redemption, shall have been made or provided for, and all funds
available to the Institutional Trustee shall first be applied to the payment in
full in cash of all Distributions (including Additional Amounts, if applicable)
on, or Redemption Price of, the Trust's Preferred Securities then due and
payable.
 
     In the case of any Event of Default under the Declaration resulting from an
Indenture Event of Default, the Company as holder of the Trust's Common
Securities will be deemed to have waived any right to act with respect to any
such Event of Default under the Declaration until the effect of all such Events
of Default with respect to the Preferred Securities have been cured, waived or
otherwise eliminated. Until any such Events of Default under the Declaration
have been so cured, waived or otherwise eliminated, the Institutional Trustee
shall act solely on behalf of the holders of the Preferred Securities and not on
behalf of the Company as holder of the Trust's Common Securities, and only the
holders of the Preferred Securities will have the right to direct the
Institutional Trustee to act on their behalf.
 
LIQUIDATION DISTRIBUTION UPON DISSOLUTION
 
     Unless otherwise specified in the applicable Prospectus Supplement,
pursuant to the Declaration, the Trust shall dissolve (i) on             , 2005,
the expiration of the term of the Trust, (ii) upon the bankruptcy of the
Company, (iii) upon the filing of a certificate of dissolution or its equivalent
with respect to the Company, after receipt by the Institutional Trustee of
written direction from the Company to dissolve the Trust or after obtaining the
consent of the holders of at least a majority in liquidation amount of the Trust
Securities affected thereby voting together as a single class to dissolve the
Trust, or the revocation of the charter of the Company and the expiration of 90
days after the date of revocation without a reinstatement thereof, (iv) upon the
distribution of Debentures, (v) upon the entry of a decree of a judicial
dissolution of the holder of the Common Securities, the Company or the Trust, or
(vi) upon the redemption of all the Trust Securities.
 
                                       24
<PAGE>   28
 
     If an early dissolution occurs as described in clause (ii), (iii) or (v)
above, the Trust shall be liquidated by the Kennametal Trustees as expeditiously
as the Kennametal Trustees determine to be possible by distributing, after
satisfaction of liabilities to creditors of the Trust as provided by applicable
law, to the holders of the applicable Trust Securities a Like Amount of the
Debentures that are then held by the Trust, unless such distribution is
determined by the Institutional Trustee not to be practical, in which event such
holders will be entitled to receive out of the assets of the Trust available for
distribution to holders, after satisfaction of liabilities to creditors of the
Trust as provided by applicable law, an amount equal to, in the case of holders
of Preferred Securities, the aggregate of the liquidation amount plus accrued
and unpaid Distributions thereon to the date of payment (such amount being the
"Liquidation Distribution"). If such Liquidation Distribution can be paid only
in part because the Trust has insufficient assets available to pay in full the
aggregate Liquidation Distribution, then the amounts payable directly by the
Trust on the Preferred Securities shall be paid on a pro rata basis. The
holder(s) of the Trust's Common Securities will be entitled to receive
distributions upon any such liquidation pro rata with the holders of the
Preferred Securities, except that if an Indenture Event of Default has occurred
and is continuing, the Preferred Securities shall have a priority over the
Common Securities. If specified in the applicable Prospectus Supplement, a
supplemental Indenture may provide that if an early dissolution occurs as
described in clause (v) above, the Debentures that are then held by the Trust
may be subject to optional redemption in whole (but not in part).
 
EVENTS OF DEFAULT; NOTICE
 
     Any one of the following events constitutes an "Event of Default" under the
Declaration (an "Event of Default") with respect to the Preferred Securities
issued thereunder (whatever the reason for such Event of Default and whether it
shall be voluntary or involuntary or be effected by operation of law or pursuant
to any judgment, decree or order of any court or any order, rule or regulation
of any administrative or governmental body):
 
     (i) the occurrence of an Indenture Event of Default under the Indenture
(see "Description of Debentures-- Indenture Events of Default"); or
 
     (ii) default by the Trust in the payment of any Distribution when it
becomes due and payable, and continuation of such default for a period of 30
days; or
 
     (iii) default by the Trust in the Payment of any Redemption Price of any
Trust Security when it becomes due and payable; or
 
     (iv) default in the performance, or breach, in any material respect, of any
covenant or warranty of the Kennametal Trustees in the Declaration (other than a
covenant or warranty a default in the performance of which or the breach of
which is dealt with in clause (ii) or (iii) above), and continuation of such
default or breach for a period of 90 days after written notice has been given to
the defaulting Kennametal Trustee or Trustees by the holders of at least 25% in
aggregate liquidation amount of the outstanding Preferred Securities, which
notice shall specify such default or breach and require it to be remedied and
shall state that such notice is a "Notice of Default" under the Declaration; or
 
     (v) the occurrence of certain events of bankruptcy or insolvency with
respect to the Institutional Trustee and the failure by the Company to appoint a
successor Institutional Trustee within 60 days thereof.
 
     Within five Business Days after the occurrence of any Event of Default
actually known to the Institutional Trustee, the Institutional Trustee shall
transmit notice of such Event of Default to the holders of the Preferred
Securities, the Regular Trustees and the Company, as Sponsor, unless such Event
of Default shall have been cured or waived. The Company, as Sponsor, and the
Regular Trustees are required to file annually with the Institutional Trustee a
certificate as to whether or not they are in compliance with all the conditions
and covenants applicable to them under the Declaration.
 
     If an Indenture Event of Default has occurred and is continuing, the
Preferred Securities of the Trust shall have a preference over the Common
Securities of the Trust upon dissolution of the Trust as described above. See
"--Liquidation Distribution Upon Dissolution." The existence of an Event of
Default does not entitle the holders of Preferred Securities to accelerate the
maturity thereof.
 
                                       25
<PAGE>   29
 
REMOVAL OF KENNAMETAL TRUSTEES
 
     Unless an Indenture Event of Default shall have occurred and be continuing,
any Kennametal Trustee may be removed at any time by the holder of the Common
Securities. If an Indenture Event of Default with respect to any series of
Debentures has occurred and is continuing, the Institutional Trustee and the
Delaware Trustee may be removed at such time by the holders of a majority in
liquidation amount of the outstanding Preferred Securities of the Trust. In no
event will the holders of the Preferred Securities of the Trust have the right
to vote to appoint, remove or replace the Administrative Trustees, which voting
rights are vested exclusively in the Company as the holder of the Common
Securities of the Trust. No resignation or removal of an Kennametal Trustee and
no appointment of a successor trustee shall be effective until the acceptance of
appointment by the successor trustee in accordance with the provisions of the
Declaration.
 
CO-TRUSTEES AND SEPARATE INSTITUTIONAL TRUSTEE
 
     Unless an Event of Default with respect to the Preferred Securities of the
Trust shall have occurred and be continuing, at any time or times, for the
purpose of meeting the legal requirements of the Trust Indenture Act or of any
jurisdiction in which any part of the trust property ("Trust Property") may at
the time be located, the Company, as the holder of the Common Securities of the
Trust, and the Regular Trustees shall have power to appoint one or more persons
either to act as a co-trustee, jointly with the Institutional Trustee, of all or
any part of such Trust Property, or to act as separate trustee of any such
property, in either case with such powers as may be provided in the instrument
of appointment, and to vest in such person or persons in such capacity any
property, title, right or power deemed necessary or desirable, subject to the
provisions of the applicable Declaration. In case an Indenture Event of Default
has occurred and is continuing, the Institutional Trustee alone shall have power
to make such appointment.
 
MERGER OR CONSOLIDATION OF TRUST TRUSTEES
 
     Any entity into which the Institutional Trustee, the Delaware Trustee or
any Regular Trustee that is not a natural person may be merged or converted or
with which it may be consolidated, or any entity resulting from any merger,
conversion or consolidation to which such Trustee shall be a party, or any
entity succeeding to all or substantially all the corporate trust business of
such Trustee, shall be the successor of such Trustee under the Declaration,
provided such entity shall be otherwise qualified and eligible.
 
MERGERS, CONSOLIDATIONS OR AMALGAMATIONS
 
     The Trust may not consolidate, amalgamate, merge with or into, or be
replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety, to any corporation or other body, except as
described below or as described in "Liquidation Distribution Upon Dissolution".
The Trust may, with the consent of the Regular Trustees and without the consent
of the holders of the Trust Securities, consolidate, amalgamate, merge with or
into, or be replaced by a trust organized as such under the laws of any State;
provided, that (i) if the Trust is not the survivor, such successor entity
either (x) assumes all of the obligations of the Trust under the Trust
Securities or (y) substitutes for the Trust Securities other securities having
substantially the same terms as the Trust Securities (the "Successor
Securities"), so long as the Successor Securities rank the same as the Trust
Securities rank with respect to distributions and payments upon liquidation,
redemption and otherwise, (ii) the Company expressly acknowledges a trustee of
such successor entity possessing the same powers and duties as the Institutional
Trustee as the holder of the Debentures, (iii) the Preferred Securities or any
Successor Securities are listed, or any Successor Securities will be listed upon
notification of issuance, on any national securities exchange or with another
organization on which the Preferred Securities are then listed or quoted, (iv)
such merger, consolidation, amalgamation or replacement does not cause the
Preferred Securities (including any Successor Securities) to be downgraded by
any nationally recognized statistical rating organization, (v) such merger,
consolidation, amalgamation or replacement does not adversely affect the rights,
preferences and privileges of the holders of the Trust Securities (including any
Successor Securities) in any material respect (other than with respect to any
dilution of the holders' interest in the new entity), (vi) such successor entity
has a purpose substantially identical to that of the Trust, (vii) prior to such
merger, consolidation, amalgamation or replacement, the Company has received an
opinion of independent counsel to the Trust experienced in such matters to the

effect that, (A) such merger, consolidation, amalgamation or replacement does
not adversely affect the rights, preferences and privileges of the holders of
the Trust Securities (including any Successor Securities) in any material
respect (other than with respect to any dilution of the holders' interest in the
new entity), (B) following such merger, consolidation, amalgamation or
replacement, neither the Trust nor such successor entity will be required to
register as an investment company under the 1940 Act and (C) following such
merger, consolidation, amalgamation or replacement, the Trust (or the successor
entity) will continue to be classified as a grantor trust for United States
federal income tax purposes and (viii) the Company guarantees the obligations of
such successor entity under the Successor Securities at least to the extent
provided by the Guarantee and the Common Securities Guarantee. Notwithstanding
the foregoing, the Trust shall not, except with the consent of holders of 100%
in liquidation amount of the Trust Securities, consolidate, amalgamate, merge
with or into, or be replaced by any other entity or permit any other entity to
consolidate, amalgamate, merge with or into, or replace it, if such
consolidation, amalgamation, merger or replacement would cause the Trust or the
successor entity to be classified as other than a grantor trust for United
States federal income tax purposes.
 
VOTING RIGHTS; AMENDMENT OF DECLARATION
 
     Except as provided below and under "Description of the
Guarantee--Modification of the Guarantee; Assignment" and as otherwise required
by law and the Declaration, the holders of the Preferred Securities will have no
voting rights.
 
     Subject to the requirement of the Institutional Trustee obtaining a tax
opinion in certain circumstances set forth in the last sentence of this
paragraph, the holders of a majority in aggregate liquidation amount of the
Preferred Securities have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Institutional Trustee,
or direct the exercise of any trust or power conferred upon the Institutional
Trustee under the Declaration including the right to direct the Institutional
Trustee, as holder of the Debentures, to (i) exercise the remedies available
under the Indenture with respect to the Debentures, (ii) waive any past
Indenture Event of Default that is waivable under Section   of the Indenture,
(iii) exercise any right to rescind or annul a declaration that the principal of
all the Debentures shall be due and payable or (iv) consent to any amendment,
modification or termination of the Indenture or the Debentures where such
consent shall be required; provided, however, that, where a consent or action
under the Indenture would require the consent or act of holders of more than a
majority in principal amount of the Debentures (a "Super-Majority") affected
thereby, only the holders of at least such Super-Majority in aggregate
liquidation amount of the Preferred Securities may direct the Institutional
Trustee to give such consent or take such action. The Institutional Trustee
shall notify all holders of the Preferred Securities of any notice of default
received from the Debt Trustee with respect to the Debentures. Such notice shall
state that such Indenture Event of Default also constitutes an Event of Default.
Except with respect to directing the time, method and place of conducting a
proceeding for a remedy, the Institutional Trustee shall not take any of the
actions described in clause (i), (ii) or (iii) above unless the Institutional
Trustee has obtained an opinion of tax counsel experienced in such matters to
the effect that, as a result of such action, the Trust will not fail to be
classified as a grantor trust for United States federal income tax purposes.
 
     In the event the consent of the Institutional Trustee, as a holder of the
Debentures, is required under the Indenture with respect to any amendment,
modification or termination of the Indenture, the Institutional Trustee shall
request the direction of the holders of the Trust Securities with respect to
such amendment, modification or termination and shall vote with respect to such
amendment, modification or termination as directed by a majority in liquidation
amount of the Trust Securities voting together as a single class; provided,
however, that where a consent under the Indenture would require the consent of a
Super-Majority, the Institutional Trustee may only give such consent at the
direction of the holders of at least the proportion in liquidation amount of the
Trust Securities which the relevant Super-Majority represents of the aggregate
principal amount of the Debentures outstanding. The Institutional Trustee shall
be under no obligation to take any such action in accordance with the directions
of the holders of the Trust Securities unless the Institutional Trustee has
obtained an opinion of tax counsel experienced in such matters to the effect
that for the purposes of United States federal income tax, the Trust will not be
classified as other than a grantor trust.
 
     A waiver of an Indenture Event of Default will constitute a waiver of the
corresponding Event of Default.
 
                                       27
<PAGE>   31
 
     Any required approval or direction of holders of Preferred Securities may
be given at a separate meeting of holders of Preferred Securities convened for
such purpose, at a meeting of all of the holders of Trust Securities or pursuant
to written consent. The Regular Trustees will cause a notice of any meeting at
which holders of Preferred Securities are entitled to vote, or of any matter
upon which action by written consent of such holders is to be taken, to be
mailed to each holder of record of Preferred Securities. Each such notice will
include a statement setting forth the following information: (i) the date of
such meeting or the date by which such action is to be taken; (ii) a description
of any resolution proposed for adoption at such meeting on which such holders
are entitled to vote or of such matter upon which written consent is sought; and
(iii) instructions for the delivery of proxies or consents. No vote or consent
of the holders of Preferred Securities will be required for the Trust to redeem
and cancel Preferred Securities or distribute Debentures in accordance with the
Declaration.
 
     Notwithstanding that holders of Preferred Securities are entitled to vote
or consent under any of the circumstances described above, any of the Preferred
Securities that are owned at such time by the Company or any entity directly or
indirectly controlling or controlled by, or under direct or indirect common
control with, the Company, shall not be entitled to vote or consent and shall,
for purposes of such vote or consent, be treated as if such Preferred Securities
were not outstanding.
 
     The procedures by which holders of Preferred Securities may exercise their
voting rights are described below. See "Book-Entry Issuance" below.
 
     Holders of the Preferred Securities will have no rights to appoint or
remove the Kennametal Trustees, who may be appointed, removed or replaced solely
by the Company as the indirect or direct holder of all of the Common Securities.
 
GLOBAL PREFERRED SECURITIES
 
     The Preferred Securities of the Trust may be issued in whole or in part in
the form of one or more Global Preferred Securities that will be deposited with,
or on behalf of, the depositary identified in the Prospectus Supplement relating
to the Preferred Securities. Unless otherwise indicated in the applicable
Prospectus Supplement for the Preferred Securities, the depositary will be The
Depository Trust Company ("DTC"). Global Preferred Securities may be issued only
in fully registered form and in either temporary or permanent form. Unless and
until it is exchanged in whole or in part for the individual Preferred
Securities represented thereby, a Global Preferred Security may not be
transferred except as a whole by the depositary for such Global Preferred
Security to a nominee of such depositary or by a nominee of such depositary to
such depositary or another nominee of such depositary or by such depositary or
any nominee to a successor depositary or any nominee of such successor.
 
     While the specific terms of the depositary arrangement with respect to the
Preferred Securities of the Trust (if other than as described under "Book-Entry
Issuance") will be described in the Prospectus Supplement relating to the
Preferred Securities, the Company anticipates that the following provisions will
generally apply to depositary arrangements.
 
     Upon the issuance of a Global Preferred Security, and the deposit of such
Global Preferred Security with or on behalf of the applicable depositary, the
depositary for such Global Preferred Security or its nominee will credit, on its
book-entry registration and transfer system, the respective aggregate
liquidation amounts of the individual Preferred Securities represented by such
Global Preferred Securities to the accounts of Participants. Such accounts shall
be designated by the dealers, underwriters or agents with respect to such
Preferred Securities or by the Company if such Preferred Securities are offered
and sold directly by the Company. Ownership of beneficial interests in a Global
Preferred Security will be limited to Participants or persons that may hold
interests through Participants. Ownership of beneficial interests in such Global
Preferred Security will be shown on, and the transfer of that ownership will be
effected only through, records maintained by the applicable depositary or its
nominee (with respect to interests of Participants) and the records of
Participants (with respect to interests of persons who hold through
Participants). The laws of some states require that certain purchasers of
securities take physical delivery of such securities in definitive form. Such
limits and such laws may impair the ability to transfer beneficial interests in
a Global Preferred Security.
 
                                       28
<PAGE>   32
 
     So long as the depositary for a Global Preferred Security, or its nominee,
is the registered owner of such Global Preferred Security, such depositary or
such nominee, as the case may be, will be considered the sole owner or holder of
the Preferred Securities represented by such Global Preferred Security for all
purposes under the Declaration. Except as provided below, owners of beneficial
interests in a Global Preferred Security will not be entitled to have any of the
individual Preferred Securities represented by such Global Preferred Security
registered in their names, will not receive or be entitled to receive physical
delivery of any such Preferred Securities in definitive form and will not be
considered the owners or holders thereof under the Declaration.
 
     Payments of liquidation amount, premium or Distributions in respect of
individual Preferred Securities represented by a Global Preferred Security
registered in the name of a depositary or its nominee will be made to such
depositary or its nominee, as the case may be, as the registered owner of the
Global Preferred Security representing such Preferred Securities. None of the
Company, the Institutional Trustee, any paying agent or the registrar for such
Preferred Securities will have any responsibility or liability for any aspect of
the records relating to or payments made on account of beneficial ownership
interests of the Global Preferred Security representing such Preferred
Securities or for maintaining, supervising or reviewing any records relating to
such beneficial ownership interests.
 
     The Company expects that the depositary for the Preferred Securities of the
Trust, or its nominee, upon receipt of any payment of liquidation amount,
premium or Distributions in respect of a Global Preferred Security representing
any of such Preferred Securities, immediately will credit Participants' accounts
with payments in amounts proportionate to their respective beneficial interest
in the aggregate of such Global Preferred Security for such Preferred Securities
as shown on the records of such depositary or its nominee. The Company also
expects that payments by Participants to owners of beneficial interests in such
Global Preferred Security held through such Participants will be governed by
standing instructions and customary practices, as is now the case with
securities held for the accounts of customers in bearer form or registered in
"street name." Such payments will be the responsibility of such Participants.
 
     Unless otherwise specified in the applicable Prospectus Supplement, if a
Depositary for the Preferred Securities of a Trust is at any time unwilling,
unable or ineligible to continue as a depositary and a successor depositary is
not appointed by the Company within 90 days, the Trust will issue individual
Preferred Securities of the Trust in exchange for the Global Preferred Security
representing such Preferred Securities. In addition, the Company may at any time
and in its sole discretion, subject to any limitations described in the
Prospectus Supplement relating to the Preferred Securities, determine not to
have any Preferred Securities of the Trust represented by one or more Global
Preferred Securities and, in such event, the Trust will issue individual
Preferred Securities in exchange for the Global Preferred Security or Securities
representing such Preferred Securities. Further, if the Company so specifies
with respect to the Preferred Securities of the Trust, an owner of a beneficial
interest in a Global Preferred Security representing such Preferred Securities
may, on terms acceptable to the Company, the Institutional Trustee and the
Depositary for such Global Preferred Security, receive individual Preferred
Securities in exchange for such beneficial interests, subject to any limitations
described in the Prospectus Supplement relating to such Preferred Securities. In
any such instance, an owner of a beneficial interest in a Global Preferred
Security will be entitled to physical delivery of individual Preferred
Securities represented by such Global Preferred Security equal in liquidation
amount to such beneficial interest and to have such Preferred Securities
registered in its name. Individual Preferred Securities so issued will be issued
in denominations, unless otherwise specified by the Company, of $50 and integral
multiples thereof.
 
PAYMENT AND PAYING AGENCY
 
     Payments in respect of the Preferred Securities shall be made to the
applicable depositary, which shall credit the relevant accounts at such
depositary on the applicable Distribution Dates or, if the Preferred Securities
are not held by a depositary, such payments shall be made by check mailed to the
address of the holder entitled thereto as such address shall appear on the
Register. Unless otherwise specified in the applicable Prospectus Supplement,
the paying agent for the Preferred Securities shall initially be the
Institutional Trustee and any co-paying agent chosen by the Institutional
Trustee and acceptable to the Regular Trustees and the Company. The paying agent
shall be permitted to resign as paying agent upon 30 days' written notice to the
Institutional Trustees and the Company. In the event that the Institutional
Trustee shall no longer be the paying agent, the Regular Trustees
 
                                       29
<PAGE>   33
 
shall appoint a successor to act as paying agent (which shall be a bank or trust
company acceptable to the Regular Trustees and the Company).
 
REGISTRAR AND TRANSFER AGENT
 
     Unless otherwise specified in the applicable Prospectus Supplement, the
Institutional Trustee will act as registrar and transfer agent for the Preferred
Securities.
 
     Registration of transfers of Preferred Securities will be effected without
charge by or on behalf of the Trust, but upon payment of any tax or other
governmental charges that may be imposed in connection with any transfer or
exchange. The Trust will not be required to register or cause to be registered
the transfer of the Preferred Securities after the Preferred Securities have
been called for redemption.
 
INFORMATION CONCERNING THE INSTITUTIONAL TRUSTEE
 
     The Institutional Trustee, other than during the occurrence and continuance
of an Event of Default, undertakes to perform only such duties as are
specifically set forth in the Declaration and, after such Event of Default, must
exercise the same degree of care and skill as a prudent person would exercise or
use in the conduct of his or her own affairs. Subject to this provision, the
Institutional Trustee is under no obligation to exercise any of the powers
vested in it by the Declaration at the request of any holder of Preferred
Securities unless it is offered reasonable indemnity against the costs, expenses
and liabilities that might be incurred thereby. If no Event of Default has
occurred and is continuing and the Institutional Trustee is required to decide
between alternative causes of action, construe ambiguous provisions in the
Declaration or is unsure of the application of any provision of the Declaration,
and the matter is not one on which holders of Preferred Securities are entitled
under the Declaration to vote, then the Institutional Trustee shall take such
action as is directed by the Company and if not so directed, shall take such
action as it deems advisable and in the best interests of the holders of the
Trust Securities and will have no liability except for its own bad faith,
negligence or willful misconduct.
 
MISCELLANEOUS
 
     The Regular Trustees are authorized and directed to conduct the affairs of
and to operate the Trust in such a way that the Trust will not be deemed to be
an "investment company" required to be registered under the Investment Company
Act or fail to be classified as a grantor trust for U.S. federal income tax
purposes and so that the Debentures will be treated as indebtedness of the
Company for U.S. federal income tax purposes. In this connection, the Company
and the Regular Trustees are authorized to take any action, not inconsistent
with applicable law, the certificate of trust of the Trust or the Declaration,
that the Company and the Regular Trustees determine in their discretion to be
necessary or desirable for such purposes, as long as such action does not
materially adversely affect the interests of the holders of the Preferred
Securities.
 
     Holders of the Preferred Securities have no preemptive or similar rights.
 
     The Trust may not borrow money or issue debt or mortgage or pledge any of
its assets.
 
                          DESCRIPTION OF THE GUARANTEE
 
     Set forth below is a summary of information concerning the Guarantee which
will be executed and delivered by the Company for the benefit of the holders
from time to time of Preferred Securities. The Guarantee will be qualified as an
indenture under the Trust Indenture Act.           , an independent trustee,
will act as indenture trustee under the Guarantee (the "Guarantee Trustee") for
the purposes of compliance with the provisions of the Trust Indenture Act. The
terms of the Guarantee will be those set forth in the Guarantee and those made
part of the Guarantee by the Trust Indenture Act. The following summary is not
necessarily complete, and reference is hereby made to the copy of the form of
the Guarantee (including the definitions therein of certain terms) which is
filed as an exhibit to the Registration Statement of which this Prospectus forms
a part, and to the Trust Indenture Act. Whenever particular defined terms of the
Guarantee are referred to in this Prospectus, such defined terms are
incorporated herein by reference. The Guarantee will be held by the Trustee for
the benefit of the holders of the Preferred Securities.
 
                                       30
<PAGE>   34
 
GENERAL
 
     Pursuant to the Guarantee, unless otherwise specified in the applicable
Prospectus Supplement, the Company will irrevocably and unconditionally agree,
to the extent set forth therein, to pay in full to the holders of the Preferred
Securities issued by the Trust, the Guarantee Payments (as defined herein)
(except to the extent paid by the Trust), as and when due, regardless of any
defense, right of set-off or counterclaim which the Trust may have or assert.
The following payments or distributions with respect to Preferred Securities
issued by the Trust, to the extent not paid by or on behalf of the Trust (the
"Guarantee Payments"), will be subject to the Guarantee (without duplication):
(i) any accrued and unpaid distributions which are required to be paid on the
Preferred Securities, to the extent the Trust shall have funds available
therefor; (ii) with respect to any Preferred Securities called for redemption by
the Trust, the redemption price (the "Redemption Price") and all accrued and
unpaid distributions to the date of redemption, to the extent the Trust has
funds available therefor and (iii) upon a voluntary or involuntary dissolution,
winding-up or termination of the Trust (other than in connection with the
distribution of Debentures to the holders of Preferred Securities or the
redemption of all of the Preferred Securities), the lesser of (a) the aggregate
of the liquidation amount and all accrued and unpaid distributions on the
Preferred Securities to the date of payment, to the extent the Trust has funds
available therefor, and (b) the amount of assets of the Trust remaining
available for distribution to holders of the Preferred Securities in liquidation
of the Trust. The Company's obligation to make a Guarantee Payment may be
satisfied by direct payment of the required amounts by the Company to the
holders of Preferred Securities or by causing the Trust to pay such amounts to
such holders.
 
     The Guarantee will be a full and unconditional guarantee of the Guarantee
Payments with respect to the Preferred Securities, but will not apply to any
payment of distributions except to the extent the Trust shall have funds
available therefor. If the Company does not make interest payments on the
Debentures purchased by the Trust, the Trust will not pay distributions on the
Preferred Securities issued by the Trust and will not have funds available
therefor. See "Relationship Among the Preferred Securities, the Debentures and
the Guarantee." The Guarantee, when taken together with the Company's
obligations under the Indenture and the Declaration, will have the effect of
providing a full and unconditional guarantee on a subordinated basis by the
Company of payments due on the Preferred Securities.
 
     The Company has also agreed separately to irrevocably and unconditionally
guarantee the obligations of the Trust with respect to the Common Securities
(the "Common Securities Guarantee") to the same extent as the Guarantee, except
that upon an Indenture Event of Default, holders of the Preferred Securities
shall have priority over holders of Common Securities with respect to
distributions and payments on liquidation, redemption or otherwise.
 
CERTAIN COVENANTS OF THE COMPANY
 
     In the Guarantee, the Company will covenant that, so long as any Preferred
Securities issued by the Trust remain outstanding, if there shall have occurred
any event that would constitute an event of default under the Guarantee or the
Declaration, then (a) the Company shall not declare or pay any dividend on, make
any distributions with respect to, or redeem, purchase, acquire or make a
liquidation payment with respect to, any of its capital stock (other than (i)
purchases or acquisitions of capital stock of the Company in connection with the
satisfaction by the Company of its obligations under any employee benefit plans
or the satisfaction by the Company of its obligations pursuant to any contract
or security outstanding on the date of such event requiring the Company to
purchase capital stock of the Company, (ii) as a result of a reclassification of
the Company's capital stock or the exchange or conversion of one class or series
of the Company's capital stock for another class or series of the Company's
capital stock, (iii) the purchase of fractional interests in shares of the
Company's capital stock pursuant to the conversion or exchange provisions of
such capital stock or the security being converted or exchanged, (iv) dividends
or distributions in capital stock of the Company and (v) redemptions or
purchases of any rights pursuant to the Rights Agreement any successor to the
Rights Agreement, and the declaration thereunder of a dividend of rights in the
future), (b) the Company shall not make any payment of interest, principal or
premium, if any, on or repay, repurchase or redeem any debt securities issued by
the Company which rank pari passu with or junior to the Debentures and (c) the
Company shall not make any
 
                                       31
<PAGE>   35
 
guarantee payments with respect to the foregoing (other than payments pursuant
to the Guarantee or the Common Securities Guarantee).
 
MODIFICATION OF THE GUARANTEE; ASSIGNMENT
 
     Except with respect to any changes which do not adversely affect the rights
of holders of Preferred Securities (in which case no vote will be required), the
Guarantee may be amended only with the prior approval of the holders of not less
than a majority in liquidation amount of the outstanding Preferred Securities
issued by the Trust. All guarantees and agreements contained in the Guarantee
shall bind the successors, assigns, receivers, trustees and representatives of
the Company and shall inure to the benefit of the holders of the Preferred
Securities then outstanding.
 
TERMINATION
 
     The Guarantee will terminate as to the Preferred Securities (i) upon full
payment of the Redemption Price of all Preferred Securities then outstanding,
(ii) upon distribution of the Debentures held by the Trust to the holders of the
Preferred Securities of the Trust or (iii) upon full payment of the amounts
payable in accordance with the Declaration upon liquidation of the Trust. The
Guarantee will continue to be effective or will be reinstated, as the case may
be, if at any time any holder of Preferred Securities must restore payment of
any sums paid under such Preferred Securities or the Guarantee.
 
EVENTS OF DEFAULT
 
     An event of default under the Guarantee will occur upon the failure of the
Company to perform any of its payment or other obligations thereunder.
 
     The holders of a majority in liquidation amount of the Preferred Securities
have the right to direct the time, method and place of conducting any proceeding
for any remedy available to the Guarantee Trustee in respect of the Guarantee or
to direct the exercise of any trust or power conferred upon the Guarantee
Trustee under the Guarantee. If the Guarantee Trustee fails to enforce the
Guarantee, any holder of Preferred Securities may institute a legal proceeding
directly against the Company to enforce such holder's rights under the
Guarantee, without first instituting a legal proceeding against the Trust, the
Guarantee Trustee or any other person or entity. Notwithstanding the foregoing,
if the Company has failed to make a required guarantee payment, a holder of
Preferred Securities may directly institute a proceeding against the Company for
enforcement of the Guarantee for such payment. The Company waives any right or
remedy to require that any action be brought first against the Trust or any
other person or entity before proceeding directly against the Company.
 
STATUS OF THE GUARANTEE
 
     The Guarantee will constitute a senior unsecured obligation of the Company
and will rank pari passu with all of the Company's other senior unsecured
obligations. The terms of the Preferred Securities provide that each holder of
Preferred Securities issued by the Trust by acceptance thereof agrees to the
subordination provisions and other terms of the Guarantee.
 
     The Guarantee will constitute a guarantee of payment and not of collection
(that is, the guaranteed party may institute a legal proceeding directly against
the Guarantor to enforce its rights under the guarantee without instituting a
legal proceeding against any other person or entity).
 
INFORMATION CONCERNING THE GUARANTEE TRUSTEE
 
     The Guarantee Trustee, prior to the occurrence of a default with respect to
the Guarantee, undertakes to perform only such duties as are specifically set
forth in the Guarantee and, after default, shall exercise the same degree of
care as a prudent individual would exercise in the conduct of his or her own
affairs. Subject to such provisions, the Guarantee Trustee is under no
obligation to exercise any of the powers vested in it by the Guarantee at the
request of any holder of Preferred Securities, unless offered reasonable
indemnity against the costs, expenses and liabilities which might be incurred
thereby; but the foregoing shall not relieve the Guarantee
 
                                       32
<PAGE>   36
 
Trustee, upon the occurrence of an event of default under the Guarantee, from
exercising the rights and powers vested in it by the Guarantee.
 
GOVERNING LAW
 
     The Guarantee will be governed by and construed in accordance with the
internal laws of the State of New York.
 
          RELATIONSHIP AMONG THE PREFERRED SECURITIES, THE DEBENTURES
                               AND THE GUARANTEE
 
     As long as payments of interest and other payments are made when due on the
Debentures, such payments will be sufficient to cover Distributions and other
payments due on the Preferred Securities, primarily because (i) the aggregate
principal amount of the Debentures will be equal to the sum of the aggregate
stated liquidation amount of the Preferred Securities and Common Securities;
(ii) the interest rate and interest and other payment dates on the Debentures
will match the Distribution rate and Distribution and other payment dates for
the Preferred Securities; (iii) the Company shall be obligated to pay, directly
or indirectly, all costs, expenses, debts and obligations of the Trust (other
than with respect to the Trust Securities); and (iv) the Declaration further
provides that the Trust will not engage in any activity that is not consistent
with the limited purposes of the Trust.
 
     Payments of Distributions and other amounts due on the Preferred Securities
(to the extent the Trust has funds available for the payment of such
Distributions) are irrevocably guaranteed by the Company as and to the extent
set forth under "Description of the Guarantee." Taken together, the Company's
obligations under a series of Debentures, the Indenture, the Declaration and the
Guarantee have the effect of providing a full, irrevocable and unconditional
guarantee of payments of Distributions and other amounts due on the Preferred
Securities. No single document standing alone or operating in conjunction with
fewer than all of the other documents constitutes such guarantee. It is only the
combined operation of these documents that has the effect of providing a full,
irrevocable and unconditional guarantee of the Trust's obligations under the
Preferred Securities. If and to the extent that the Company does not make
payments on the Debentures, the Trust will not pay Distributions or other
amounts due on the Preferred Securities. The Guarantee does not cover payment of
Distributions when the Trust does not have sufficient funds to pay such
Distributions. In such event, the remedy of a holder of Preferred Securities is
to institute a legal proceeding directly against the Company for enforcement of
payment of such Distributions to such holder.
 
     Notwithstanding anything to the contrary in the Indenture, the Company has
the right to set-off any payment it is otherwise required to make thereunder
with and to the extent the Company has theretofor made, or is concurrently on
the date of such payment making, a payment under the Guarantee.
 
     A holder of any Preferred Security may institute a legal proceeding
directly against the Company to enforce its rights under the Guarantee without
first instituting a legal proceeding against the Guarantee Trustee, the Trust or
any other person or entity.
 
     The Trust's Preferred Securities evidence preferred undivided beneficial
interests in the assets of the Trust, and each Trust exists for the sole purpose
of issuing the Preferred Securities and Common Securities and investing the
proceeds thereof in Debentures. A principal difference between the rights of a
holder of a Preferred Security and a holder of a Debenture is that a holder of a
Debenture will accrue, and (subject to the permissible extension of the interest
period) is entitled to receive, interest on the principal amount of Debentures
held, while a holder of Preferred Securities is only entitled to receive
Distributions if and to the extent the Trust has funds available for the payment
of such Distributions.
 
     Upon any voluntary or involuntary dissolution of the Trust involving the
liquidation of the Debentures, the holders of Preferred Securities of the Trust
will be entitled to receive, out of assets held by the Trust, the Liquidation
Distribution in cash. See "Description of Preferred Securities--Liquidation
Distribution Upon Dissolution." Upon any voluntary or involuntary liquidation or
bankruptcy of the Company, the Institutional Trustee as holder of the Debentures
would be entitled to receive payment in full of principal and interest, before
any stockholders of the Company receive payments or distributions.
 
                                       33
<PAGE>   37
 
     A default or event of default under any Senior Indebtedness would not
constitute a default or Indenture Event of Default under the Indenture. However,
in the event of payment defaults under, or acceleration of, Senior Indebtedness,
the subordination provisions of the Indenture provide that no payments may be
made in respect of the Debentures until such Senior Indebtedness has been paid
in full or any payment default thereunder has been cured or waived. Failure to
make required payments on any Debentures would constitute an Indenture Event of
Default under the Indenture.
 
                          DESCRIPTION OF COMMON STOCK
 
     The following brief description of the Company's capital stock does not
purport to be complete and is subject in all respects to applicable Pennsylvania
law and to the provisions of the Company's Amended and Restated Articles of
Incorporation (the "Restated Articles") and its Amended and Restated By-Laws
(the "Restated By-Laws"), copies of which have been filed with the Commission.
 
COMMON STOCK
 
     The Company has authorized 70,000,000 shares of Capital Stock, par value
$1.25 per share ("Common Stock"). As of October 31, 1997, there were 26,264,454
shares of Common Stock outstanding. Holders of Common Stock are entitled to such
dividends as may be declared by the Board of Directors out of funds legally
available therefor after payment of dividends on any outstanding Preferred Stock
and are entitled to one vote for each share of Common Stock held by them with
respect to all matters upon which they are entitled to vote.
 
PREFERRED STOCK
 
     The Company has authorized 5,000,000 shares of Class A Preferred Stock, no
par value per share (the "Preferred Stock"). At present there are no shares of
Preferred Stock outstanding. The Board of Directors of the Company, without
further action by the stockholders, is authorized to designate and issue in
series Preferred Stock and to fix as to any series the dividend rate, redemption
prices, preferences on dissolution, the terms of any sinking fund, conversion
rights, voting rights, and any other preferences or special rights and
qualifications. The Board of Directors of the Company has authorized 200,000
shares of Series One Preferred Stock for use in the Rights Plan. See "Rights
Plan".
 
     Any Preferred Stock so issued may rank senior to the Common Stock with
respect to the payment of dividends or amounts upon liquidation, dissolution or
winding up, or both. In addition, any such shares of Preferred Stock may have
class or series voting rights. Issuances of Preferred Stock, while providing the
Company with flexibility in connection with general corporate purposes, may,
among other things, have an adverse effect on the rights of holders of Common
Stock. The Company has no present plans to issue any Preferred Stock.
 
COVENANT RESTRICTIONS
 
     In connection with the acquisition of Greenfield, the Company, on November
17, 1997, entered into a bank credit facility with BankBoston, N.A., Deutsche
Bank AG, New York Branch and/or Cayman Islands Branch, Mellon Bank, N.A. and PNC
Bank, National Association (the "New Bank Credit Facility"). The Company's New
Bank Credit Facility contains financial and operating covenants, including
restrictions on the ability of the Company to, among other things, incur
additional debt, make advances and investments, create, incur or permit the
existence of certain liens, make loans or guarantees and requires the Company to
achieve and maintain certain financial ratios, including minimum net worth,
maximum leverage ratio and minimum fixed charge coverage ratio.
 
CERTAIN CHARTER AND BY-LAW PROVISIONS
 
     Certain provisions of the Restated Articles and Restated By-Laws could have
an anti-takeover effect. These provisions are intended to enhance the likelihood
of continuity and stability in the composition of the Company's Board of
Directors and in the policies formulated by the Board and to discourage an
unsolicited takeover of the
 
                                       34
<PAGE>   38
 
Company if the Board determines that such takeover is not in the best interests
of the Company and its shareholders. However, these provisions could have the
effect of discouraging certain attempts to acquire the Company or remove
incumbent management even if some or a majority of shareholders deemed such an
attempt to be in their best interests.
 
     The provisions in the Restated Articles and Restated By-Laws include (i)
the classification of the Board of Directors into three classes, (ii) a
procedure which requires shareholders to nominate directors in advance of a
meeting to elect such directors and (iii) the authority to issue additional
shares of Common Stock or Preferred Stock without shareholder approval.
 
     The Restated Articles also include a provision requiring a 75 percent
shareholder vote for certain mergers or other business combinations or
transactions with five percent shareholders; a provision requiring a 75 percent
shareholder vote to remove the entire Board, a class of the Board, any
individual member of the Board without cause, or to increase the size of the
Board to more than twelve members or decrease the size of the Board to fewer
than eight members; a provision requiring disinterested shareholder approval of
stock repurchases at a premium over market by the Company from certain four
percent Shareholders (as defined in the Restated Articles); and a provision
requiring a majority of disinterested shareholders to approve certain business
combinations involving a stockholder who beneficially owns more than 10 percent
of the voting power of the Company, unless certain minimum price, form of
consideration and procedural requirements are satisfied or the transaction is
approved by a majority of disinterested directors.
 
     Pursuant to the Restated Articles, the Board of Directors is permitted to
consider the effects of a change in control on non-shareholder constituencies of
the Company, such as its employees, suppliers, creditors, customers and the
communities in which it operates. Pursuant to this provision, the Board may be
guided by factors in addition to price and other financial considerations.
 
     PBCL Anti-Takeover Provisions.  The Pennsylvania Business Corporation Law
(the "PBCL") contains a number of statutory "anti-takeover" provisions,
including Subchapters E, F, G and H of Chapter 25 and Section 2538 of the PBCL,
which apply automatically to a Pennsylvania registered corporation (usually a
public company) unless such corporation elects to opt-out as provided in such
provisions. The Company, as a Pennsylvania registered corporation, has elected
in its Restated By-Laws to opt-out of certain of the anti-takeover provisions
entirely, namely Subchapters G and H.
 
     The following descriptions are qualified in their entirety by reference to
such provisions of the PBCL:
 
          Subchapter E (relating to control transactions) generally provides
     that if any person or group acquires 20% or more of the voting power of a
     covered corporation, the remaining shareholders may demand from such person
     or group the fair value of their shares, including a proportionate amount
     of any control premium.
 
          Subchapter F (relating to business combinations) generally delays for
     five years and imposes conditions upon "business combinations" between an
     "interested shareholder" and the corporation. The term "business
     combination" is defined broadly to include various transactions between a
     corporation and an interested shareholder including mergers, sales or
     leases of specified amounts of assets, liquidations, reclassifications and
     issuances of specified amounts of additional shares of stock of the
     corporation. An "interested shareholder" is defined generally as the
     beneficial owner of at least 20% of a corporation's voting shares.
 
          Section 2538 of the PBCL generally establishes certain shareholder
     approval requirements with respect to specified transactions with
     "interested shareholders."
 
TRANSFER AGENT AND REGISTRAR
 
     ChaseMellon Shareholder Services, L.L.C. is the Transfer Agent and
Registrar for the Common Stock.

RIGHTS AGREEMENT
 
     The Company has adopted a rights plan pursuant to which the Board of
Directors authorized and the Company distributed one preferred stock purchase
right (each a "right") for each outstanding share of Common Stock of the
Company. The terms of the rights are governed by a Rights Agreement between the
Company and Mellon Bank, N.A., as Rights Agent, dated as of October 25, 1990
(the "Rights Agreement"). The rights, which currently are automatically
transferred with the related shares of Common Stock and are not separately
transferable, will entitle the holder thereof to purchase one-hundredth of a
share of a new series of preferred stock of the Company at a price of $105
(subject to certain adjustments).
 
     Subject to certain restrictions, the rights become exercisable only if a
person or group of persons acquires or intends to make a tender offer for 20
percent or more of the Company's Common Stock. If any person acquires 20 percent
of the Common Stock, each right will entitle the shareholder to receive upon
exercise that number of shares of Common Stock having a market value of two
times the exercise price. If the Company is acquired in a merger or certain
other business combinations, each right then will entitle the shareholder to
purchase at the exercise price, that number of shares of the acquiring company
having a market value of two times the exercise price.
 
     The rights will expire on November 2, 2000, and are subject to redemption
in certain circumstances by the Company at a redemption price of $0.01 per
right.
 
     The foregoing summary description of the Rights Agreement does not purport
to be complete and is qualified in its entirety by reference to the Rights
Agreement, a copy of which has been filed with the Commission as an exhibit in
the Registration Statement of which this Prospectus forms a part. For a more
detailed description of the Rights Agreement, see the Company's Form 8-A filed
with the Commission with respect to the rights and incorporated by reference
into this Prospectus.
 
        DESCRIPTION OF STOCK PURCHASE CONTRACTS AND STOCK PURCHASE UNITS
 
     The Company may issue Stock Purchase Contracts, including contracts
obligating holders to purchase from the Company, and the Company to sell to the
holders, a specified number of shares of Common Stock or Preferred Stock at a
future date or dates. The consideration per share of Preferred Stock or Common
Stock may be fixed at the time the Stock Purchase Contracts are issued or may be
determined by reference to a specific formula set forth in the Stock Purchase
Contracts. The Stock Purchase Contracts may be issued separately or as Stock
Purchase Units consisting of a Stock Purchase Contract and Debt Securities,
Preferred Securities or debt obligations of third parties, including U.S.
Treasury securities, securing the holders' obligations to purchase the Preferred
Stock or the Common Stock under the Stock Purchase Contracts. The Stock Purchase
Contracts may require the Company to make periodic payments to the holders of
the Stock Purchase Units or vice versa, and such payments may be unsecured or
prefunded on some basis. The Stock Purchase Contracts may require holders to
secure their obligations thereunder in a specified manner.
 
     The applicable Prospectus Supplement will describe the terms of any Stock
Purchase Contracts or Stock Purchase Units. The description in the Prospectus
Supplement will not necessarily be complete, and reference will be made to the
Stock Purchase Contracts, and, if applicable, collateral arrangements and
depositary arrangements, relating to such Stock Purchase Contracts or Stock
Purchase Units.

                              BOOK ENTRY ISSUANCE
 
     Unless otherwise specified in the applicable Prospectus Supplement, DTC
will act as depositary for Securities issued in the form of Global Securities.
Such Securities will be issued only as fully-registered securities registered in
the name of Cede & Co. (DTC's nominee). One or more fully-registered Global
Securities will be issued for such Securities representing in the aggregate the
total number of such Securities, and will be deposited with or on behalf of DTC.
 
     DTC is a limited purpose trust company organized under the New York Banking
Law, a "banking organization" within the meaning of the New York Banking Law, a
member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code, and a "clearing agency"
registered pursuant to the provisions of Section 17A of the Exchange Act. DTC
holds securities that its Participants deposit with DTC. DTC also facilitates
the settlement among Participants of securities transactions, such as transfers
and pledges, in deposited securities through electronic computerized book-entry
changes in Participants' accounts, thereby eliminating the need for physical
movement of securities certificates. Direct Participants include securities
brokers and dealers, banks, trust companies, clearing corporations and certain
other organizations ("Direct Participants"). DTC is owned by a number of its
Direct Participants and by the New York Stock Exchange, Inc., the American Stock
Exchange, Inc. and the National Association of Securities Dealers, Inc. Access
to the DTC system is also available to others such as securities brokers and
dealers, banks and trust companies that clear through or maintain custodial
relationships with Direct Participants, either directly or indirectly ("Indirect
Participants"). The rules applicable to DTC and its Participants are on file
with the Commission.
 
     Purchases of Securities within the DTC system must be made by or through
Direct Participants, which will receive a credit for such Securities on DTC's
records. The ownership interest of each actual purchaser of each Security
("Beneficial Owner") is in turn to be recorded on the Direct and Indirect
Participants' records. Beneficial Owners will not receive written confirmation
from DTC of their purchases, but Beneficial Owners are expected to receive
written confirmations providing details of the transactions, as well as periodic
statements of their holdings, from the Direct or Indirect Participants through
which the Beneficial Owners purchased Securities. Transfers of ownership
interests in Securities issued in the form of Global Securities are to be
accomplished by entries made on the books of Participants acting on behalf of
Beneficial Owners. Beneficial Owners will not receive certificates representing
their ownership interests in such Securities, except in the event that use of
the book-entry system for such Securities is discontinued.
 
     DTC has no knowledge of the actual Beneficial Owners of the Securities
issued in the form of Global Securities; DTC's records reflect only the identity
of the Direct Participants to whose accounts such Securities are credited, which
may or may not be the Beneficial Owners. The Participants will remain
responsible for keeping account of their holdings on behalf of their customers.
 
     Conveyance of notices and other communications by DTC to Direct
Participants, by Direct Participants to Indirect Participants, and by Direct
Participants and Indirect Participants to Beneficial Owners will be governed by
arrangements among them, subject to any statutory or regulatory requirements as
may be in effect from time to time.
 
     Redemption notices shall be sent to Cede & Co. as the registered holder of
Securities issued in the form of Global Securities. If less than all of a series
of such Securities are being redeemed, DTC's current practice is to determine by
lot the amount of the interest of each Direct Participant to be redeemed.
 
     Although voting with respect to Securities issued in the form of Global
Securities is limited to the holders of record of such Securities, in those
instances in which a vote is required, neither DTC nor Cede & Co. will itself
consent or vote with respect to such Securities. Under its usual procedures, DTC
would mail an omnibus proxy (the "Omnibus Proxy") to the issuer of such
Securities as soon as possible after the record date. The Omnibus Proxy assigns
Cede & Co.'s consenting or voting rights to those Direct Participants to whose
accounts such Securities are credited on the record date (identified in a
listing attached to the Omnibus Proxy).
 
     Payments in respect of Securities issued in the form of Global Securities
will be made by the issuer of such Securities to DTC. DTC's practice is to
credit Direct Participants' accounts on the relevant payment date in
 
                                       37
<PAGE>   41
 
accordance with their respective holdings shown on DTC's records unless DTC has
reason to believe that it will not receive payments on such payment date.
Payments by Participants to Beneficial Owners will be governed by standing
instructions and customary practices and will be the responsibility of such
Participant and not of DTC, the Institutional Trustee, either Trust or the
Company, subject to any statutory or regulatory requirements as may be in effect
from time to time. Payments to DTC are the responsibility of the issuer of the
applicable Securities, disbursement of such payments to Direct Participants is
the responsibility of DTC, and disbursements of such payments to the Beneficial
Owners is the responsibility of Direct and Indirect Participants.
 
     DTC may discontinue providing its services as depositary with respect to
any Securities at any time by giving reasonable notice to the issuer of such
Securities. In the event that a successor depositary is not obtained, individual
Security certificates representing such Securities are required to be printed
and delivered. The Company, at its option, may decide to discontinue use of the
system of book-entry transfers through DTC (or a successor depositary).
 
     The information in this section concerning DTC and DTC's book-entry system
has been obtained from sources that the Trust and the Company believe to be
accurate, but the Trust and the Company assume no responsibility for the
accuracy thereof. Neither the Trust nor the Company has any responsibility for
the performance by DTC or its Participants of their respective obligations as
described herein or under the rules and procedures governing their respective
operations.
 
                              PLAN OF DISTRIBUTION
 
     Any of the Securities being offered hereby may be sold in any one or more
of the following ways from time to time: (i) through agents; (ii) to or through
underwriters; (iii) through dealers; and (iv) directly by the Company or, in the
case of Preferred Securities, by the Trust to purchasers.
 
     The distribution of the Securities may be effected from time to time in one
or more transactions at a fixed price or prices, which may be changed, at market
prices prevailing at the time of sale, at prices related to such prevailing
market prices or at negotiated prices.
 
     Offers to purchase Securities may be solicited by agents designated by the
Company from time to time. Any such agent involved in the offer or sale of the
Securities in respect of which this Prospectus is delivered will be named, and
any commissions payable by the Company or the Trust to such agent will be set
forth, in the applicable Prospectus Supplement. Unless otherwise indicated in
such Prospectus Supplement, any such agent will be acting on a reasonable best
efforts basis for the period of its appointment. Any such agent may be deemed to
be an underwriter, as that term is defined in the Securities Act, of the
Securities so offered and sold.
 
     If Securities are sold by means of an underwritten offering, the Company
and, in the case of an offering of Preferred Securities, the Trust will execute
an underwriting agreement with an underwriter or underwriters at the time an
agreement for such sale is reached, and the names of the specific managing
underwriter or underwriters, as well as any other underwriters, the respective
amounts underwritten and the terms of the transaction, including commissions,
discounts and any other compensation of the underwriters and dealers, if any,
will be set forth in the applicable Prospectus Supplement which will be used by
the underwriters to make resales of the Securities in respect of which this
Prospectus is being delivered to the public. If underwriters are utilized in the
sale of any Securities in respect of which this Prospectus is being delivered,
such Securities will be acquired by the underwriters for their own account and
may be resold from time to time in one or more transactions, including
negotiated transactions, at fixed public offering prices or at varying prices
determined by the underwriters at the time of sale. Securities may be offered to
the public either through underwriting syndicates represented by managing
underwriters or directly by one or more underwriters. If any underwriter or
underwriters are utilized in the sale of Securities, unless otherwise indicated
in the applicable Prospectus Supplement, the underwriting agreement will provide
that the obligations of the underwriters are subject to certain conditions
precedent and that the underwriters with respect to a sale of such Securities
will be obligated to purchase all such Securities if any are purchased.
 
     The Company or the Trust, as applicable, may grant to the underwriters
options to purchase additional Securities, to cover over-allotments, if any, at
the initial public offering price (with additional underwriting
 
                                       38
<PAGE>   42
 
commissions or discounts), as may be set forth in the Prospectus Supplement
relating thereto. If the Company or the Trust, as applicable, grants any
over-allotment option, the terms of such over-allotment option will be set forth
in the Prospectus Supplement for such Securities.
 
     If a dealer is utilized in the sale of the Securities in respect of which
this Prospectus is delivered, the Company or the Trust, as applicable, will sell
such Securities to the dealer as principal. The dealer may then resell such
Securities to the public at varying prices to be determined by such dealer at
the time of resale. Any such dealer may be deemed to be an underwriter, as such
term is defined in the Securities Act, of the Securities so offered and sold.
The name of the dealer and the terms of the transaction will be set forth in the
Prospectus Supplement relating thereto.
 
     Offers to purchase Securities may be solicited directly by the Company or
the Trust, as applicable, and the sale thereof may be made by the Company or the
Trust directly to institutional investors or others, who may be deemed to be
underwriters within the meaning of the Securities Act with respect to any resale
thereof. The terms of any such sales will be described in the Prospectus
Supplement relating thereto.
 
     Securities may also be offered and sold, if so indicated in the applicable
Prospectus Supplement, in connection with a remarketing upon their purchase, in
accordance with a redemption or repayment pursuant to their terms, or otherwise,
by one or more firms ("remarketing firms"), acting as principals for their own
accounts or as agents for the Company or the Trust, as applicable. Any
remarketing firm will be identified and the terms of its agreement, if any, with
the Company or the Trust and its compensation will be described in the
applicable Prospectus Supplement. Remarketing firms may be deemed to be
underwriters, as that term is defined in the Securities Act, in connection with
the Securities remarketed thereby.
 
     If so indicated in the applicable Prospectus Supplement, the Company or the
Trust, as applicable, may authorize agents and underwriters to solicit offers by
certain institutions to purchase Securities from the Company or the Trust at the
public offering price set forth in the applicable Prospectus Supplement pursuant
to delayed delivery contracts providing for payment and delivery on the date or
dates stated in the applicable Prospectus Supplement. Such delayed delivery
contracts will be subject to only those conditions set forth in the applicable
Prospectus Supplement. A commission indicated in the applicable Prospectus
supplement will be paid to underwriters and agents soliciting purchases of
Securities pursuant to delayed delivery contracts accepted by the Company or the
Trust, as applicable.
 
     Agents, underwriters, dealers and remarketing firms may be entitled under
relevant agreements with the Company or the Trust, as applicable, to
indemnification by the Company or the Trust against certain liabilities,
including liabilities under the Securities Act, or to contribution with respect
to payments which such agents, underwriters, dealers and remarketing firms may
be required to make in respect thereof.
 
     Each series of Securities will be a new issue and, other than the Common
Stock, which is listed on the New York Stock Exchange, will have no established
trading market. The Company may elect to list any series of Securities on an
exchange, and in the case of the Common Stock, on any additional exchange, but,
unless otherwise specified in the applicable Prospectus Supplement, the Company
shall not be obligated to do so. No assurance can be given as to the liquidity
of the trading market for any of the Securities.
 
     Agents, underwriters, dealers and remarketing firms may be customers of,
engage in transactions with, or perform services for, the Company and its
subsidiaries in the ordinary course of business.
 
                                 LEGAL MATTERS
 
     The validity of the Securities will be passed upon by Buchanan Ingersoll
Professional Corporation, Pittsburgh, Pennsylvania. William R. Newlin, Chairman
of the Board of the Company, is a shareholder in Buchanan Ingersoll Professional
Corporation. As of July 30, 1997, Mr. Newlin owned 24,385 shares of Common
Stock, stock credits representing the right to acquire 9,260 shares pursuant to
the Company's directors deferred fee plan, 20,000 shares of JLK common stock and
held options to acquire 15,000 shares of JLK common stock. Except as provided in
the applicable Prospectus Supplement, if the Securities are underwritten, the

    The securities offered hereby are FELINE PRIDES(SM) ("FELINE PRIDES" or the
"Securities") of Kennametal Inc., a Pennsylvania corporation ("Kennametal" or
the "Company"), and Kennametal Financing I, a statutory business trust created

the Company will pay the holder unsecured, subordinated contract adjustment
payments ("Contract Adjustment Payments") at the rate of       % of the Stated
Amount per annum, provided that if such rate is 0%, than the Company will not
make any Contract Adjustment Payments, and (b) either beneficial ownership of a
      % Trust Preferred Security (a "Trust Preferred Security"), having a stated
liquidation amount per Trust Preferred Security equal to the Stated Amount,
representing a preferred undivided beneficial interest in the assets of the
Trust or, upon the occurrence of a Tax Event Redemption (as defined herein)
prior to the Purchase Contract Settlement Date, the Applicable Ownership
Interest (as defined herein) in the Treasury Portfolio (as defined herein). The
Company will, directly or indirectly, own all the common securities (the "Common
Securities" and, together with the Trust Preferred Securities, the "Trust
Securities") representing undivided beneficial interests in the assets of the
Trust. The Trust exists for the sole purpose of issuing the

to be approximately $  million ($  million if the underwriters for the Common
Stock Offerings exercise their over-allotment options in full). See "Recent
Developments."
 
    Prior to the offering made hereby there has been no public market for the
Securities. Application has been made to list the Income PRIDES on the New York
Stock Exchange ("NYSE") under the symbol "      ." The Common Stock is listed on
the New York Stock Exchange and is traded under the symbol "KMT." On November

(continued from prior page)
 
Trust Securities and investing the proceeds thereof in an equivalent principal
amount of        % Debentures of the Company, due February 16, 2003 (the
"Debentures"). As long as the FELINE PRIDES are in the form of Income PRIDES,
the related Trust Preferred Securities or the Treasury Portfolio, as applicable,
will be pledged to the Collateral Agent (as defined herein), to secure the
holder's obligation to purchase Common Stock under the related Purchase
Contracts.
 
     Aggregate payments of        % of the Stated Amount per annum are scheduled
to be made or accrued on each Income PRIDES quarterly in arrears on February 16,
May 16, August 16 and November 16 of each year, commencing February 16, 1998,
until the Purchase Contract Settlement Date. These payments will consist of
cumulative cash distributions on the related Trust Preferred Securities or the
Treasury Portfolio, as applicable, payable at the rate of        % of the Stated
Amount per annum, and Contract Adjustment Payments payable by the Company at the
rate of        % of the Stated Amount per annum (provided that if such rate is
0%, then the Company will not make any Contract Adjustment Payments), subject in
the case of distributions on Trust Preferred Securities and the Contract
Adjustment Payments, to the Company's right to defer payment of such amounts.
The ability of the Trust to make the quarterly distributions on the Trust
Preferred Securities will be solely dependent upon the receipt of corresponding
interest payments from the Company on the Debentures. The Company will have the
right at any time, and from time to time, limited to a period not extending
beyond the maturity date of the Debentures, to defer the interest payments due
on the Debentures, and to defer Contract Adjustment Payments, if any, until the
Purchase Contract Settlement Date. As a consequence of such deferral, quarterly
distributions on the Income PRIDES would be deferred, but would continue to
accrue with interest compounded quarterly. If a Tax Event Redemption has
occurred prior to the Purchase Contract Settlement Date and the Treasury
Portfolio has become a component of the Income PRIDES as described herein,
quarterly distributions of the Treasury Portfolio as a portion of the cumulative
cash distributions to the holders of Income PRIDES will not be deferred.
 
     The applicable distribution rate on the Trust Preferred Securities and the
interest rate on the related Debentures that remain outstanding on and after the
Purchase Contract Settlement Date will be reset on the third Business Day
immediately preceding the Purchase Contract Settlement Date to a rate per annum
(the "Reset Rate") to be determined by the Reset Agent (as defined herein) equal
to the sum of (x) a spread amount (the "Reset Spread") to be determined by the
Reset Agent on the tenth Business Day prior to the Purchase Contract Settlement
Date and (y) the rate of interest on the Two-Year Benchmark Treasury (as defined
herein) in effect on the third Business Day immediately preceding the Purchase
Contract Settlement Date, such sum being the distribution rate the Trust
Preferred Securities should bear in order for a Trust Preferred Security to have
an approximate market value of 100.5% of the Stated Amount on the third Business
Day immediately preceding the Purchase Contract Settlement Date, provided that
the Company may limit such Reset Spread to be no higher than 200 basis points
(2%). Such market value may be less than 100.5% if the Reset Spread is limited
to a maximum of 2%.
 
     The payment of distributions and certain redemptions out of monies held by
the Trust and payments on liquidation of the Trust will be guaranteed by the
Company (the "Guarantee") to the extent described herein and under "Description
of the Guarantee." The Guarantee covers payments of distributions and other
payments on the Trust Preferred Securities only if and to the extent the Trust
has funds available therefor, which will not be the case unless the Company has
made a payment of principal or interest on the Debentures held by the Trust as
its sole asset. The Guarantee, when taken together with the Company's
obligations under the Debentures, the Indenture (as defined below) and the
Company's obligations under the Declaration (as defined below), provides a full
and unconditional guarantee by the Company of amounts due on the Trust Preferred
Securities.
 
     The Company's obligations in respect of the Debentures and the Guarantee
generally will be senior unsecured obligations of the Company. The Contract
Adjustment Payments will be subordinated and junior in right of payment only to
the Company's obligations under the Senior Indebtedness. "Senior Indebtedness"
means indebtedness of any kind of the Company unless the instrument under which
such indebtedness is incurred expressly provides that it is on parity or
subordinate in right of payment to the Contract Adjustment Payments.

     If the holder of an Income PRIDES (unless a Tax Event Redemption has
occurred) has not notified the Purchase Contract Agent by the fifth Business Day
immediately preceding the Purchase Contract Settlement Date, in the manner
described herein of its intention to settle the related Purchase Contract with
separate cash on the Business Day immediately preceding the Purchase Contract
Settlement Date, the Remarketing Agent (as defined herein), pursuant to the
terms of the Remarketing Agreement and the Remarketing Underwriting Agreement
(each as defined herein), will use its reasonable efforts to remarket the
related Trust Preferred Security on the third Business Day immediately preceding
the Purchase Contract Settlement Date for settlement on the Purchase Contract
Settlement Date at a price not less than approximately 100.5% of such Trust
Preferred Security's aggregate stated liquidation amount plus accrued and unpaid
distributions, if any, thereon. The proceeds from such remarketing, in an amount
equal to the aggregate stated liquidation amount of such Trust Preferred
Securities, will automatically be applied to satisfy in full such holder's
obligation to purchase Common Stock under the related Purchase Contract. In
addition, after deducting as a remarketing fee (the "Remarketing Fee") an amount
not exceeding 25 basis points (.25%), from any amount received in connection
with such remarketing in excess of the aggregate stated liquidation amount of
such Trust Preferred Securities, the Remarketing Agent will remit the remaining
portion of the proceeds, if any, to the Purchase Contract Agent for the benefit
of such holder. If despite using its reasonable efforts the Remarketing Agent
fails to remarket the Trust Preferred Securities at a price not less than 100%
of their aggregate stated liquidation amount plus accrued and unpaid
distributions, including deferred distributions, if any, the remarketing will be
deemed to have failed (a "Failed Remarketing") and the Company will exercise its
rights as a secured party to dispose of the Trust Preferred Securities in
accordance with applicable law and satisfy in full, from the proceeds of such
disposition, such Income PRIDES holder's obligation to purchase Common Stock
under the related Purchase Contract, provided, that if the Company exercises
such rights as a secured creditor, with respect to such Trust Preferred
Securities, any accrued and unpaid distributions (including any deferred
distributions) with respect to such Trust Preferred Securities will be paid in
cash by the Company to the holder of record (immediately prior to such Failed
Remarketing) of such Trust Preferred Securities. The Company will cause a notice
of such Failed Remarketing to be published on the second Business Day
immediately preceding the Purchase Contract Settlement Date.
 
     On or prior to the fifth Business Day immediately preceding the Purchase
Contract Settlement Date, each holder (including, initially, an Underwriter) of
an Income PRIDES (unless a Tax Event Redemption has occurred) will have the
right to substitute for the related Trust Preferred Securities held by the
Collateral Agent zero-coupon U.S. Treasury Securities (Cusip No.       ), which
are principal strips of the  % U.S. Treasury Securities which mature on February
15, 2001 (the "Treasury Securities"), in an amount per Income PRIDES equal to
the Stated Amount per Trust Preferred Security. Because Treasury Securities are
issued in integral multiples of $1,000, holders may make such substitutions only
in integral multiples of 20 Income PRIDES; provided, however, if a Tax Event
Redemption has occurred prior to the Purchase Contract Settlement Date and the
Treasury Portfolio has become a component of the Income PRIDES, holders of
Income PRIDES may make such substitutions only in integral multiples of 8,000
Income PRIDES (but obtaining the release of the Treasury Portfolio rather than
the Trust Preferred Securities) at any time on or prior to the second Business
Day immediately preceding the Purchase Contract Settlement Date. Such Treasury
Securities will be substituted for the Trust Preferred Securities or the
Treasury Portfolio, as the case may be, and will be pledged with the Collateral
Agent to secure the holder's obligation to purchase Common Stock under the
related Purchase Contracts. FELINE PRIDES with respect to which Treasury
Securities have been substituted for the related Trust Preferred Securities or
the Treasury Portfolio, as the case may be, as collateral to secure such
obligation are referred to herein as Growth PRIDES(SM) (the "Growth PRIDES").
Each Growth PRIDES will consist of a unit with a face amount of $50 comprised of
(a) a Purchase Contract under which (i) the holder will purchase from the
Company on the Purchase Contract Settlement Date for an amount of cash equal to
the Stated Amount of such Growth PRIDES a number of newly issued shares of
Common Stock of the Company equal to the Settlement Rate described herein and
(ii) the Company will pay the holder Contract Adjustment Payments, at the rate
of      % of the Stated Amount per annum, provided that if such rate is 0%, then
the Company will not make any Contract Adjustment Payments, and (b) a 1/20
undivided beneficial ownership interest in a related Treasury Security having a
principal amount at maturity equal to $1,000 and maturing on the Business Day
immediately preceding the Purchase Contract Settlement Date. Upon the
substitution of Treasury Securities for the related Trust Preferred Securities
or the Treasury Portfolio, as the case may be, as collateral, such Trust
Preferred Securities or Treasury Portfolio, as the
 
                                       S-4
<PAGE>   49
 
case may be, will be released to the holder as described herein and thereafter
will trade separately from the resulting Growth PRIDES. Contract Adjustment
Payments, if any, will be payable by the Company on the Growth PRIDES on
February 16, May 16, August 16 and November 16 of each year. In addition
original issue discount will continue to accrue on the related Treasury
Securities. A holder of Growth PRIDES will have the right to subsequently
recreate Income PRIDES at any time on or prior to the fifth Business Day
immediately preceding the Purchase Contract Settlement Date by delivering 20
Growth PRIDES to the Purchase Contract Agent plus 20 Trust Preferred Securities
to the Collateral Agent in exchange for 20 Income PRIDES and the release of the
related Treasury Security to such holder; provided, however, if a Tax Event
Redemption has occurred prior to the Purchase Contract Settlement Date and the
Treasury Portfolio has become a component of the Income PRIDES, holders of
Growth PRIDES may make such substitution only in integral multiples of 8,000
Growth PRIDES (but using the Treasury Portfolio rather than Trust Preferred
Securities) at any time on or prior to the second Business Day immediately
preceding the Purchase Contract Settlement Date. Such Trust Preferred Securities
or Treasury Portfolio, as the case may be, will be substituted for the Treasury
Security and will be pledged with the Collateral Agent to secure the holder's
obligation to purchase Common Stock under the related Purchase Contracts.
 
     If a Failed Remarketing has occurred, holders of Trust Securities
(including, following the distribution of the Debentures upon a dissolution of
the Trust as described herein, such Debenture holders), holding such Trust
Securities or Debentures, as the case may be, following the Purchase Contract
Settlement Date will have the right, in the case of Trust Securities, to require
the Trust to put to the Company the related Debentures, or in the case of
Debentures, to put such Debentures directly to the Company on March      , 2001,
upon at least three Business Days' prior notice.
 
     On the Business Day immediately preceding the Purchase Contract Settlement
Date, unless a holder of Income PRIDES or Growth PRIDES (i) has settled the
related Purchase Contracts through the early delivery of cash to the Purchase
Contract Agent in the manner described herein, (ii) has settled the related
Purchase Contracts with separate cash on the Business Day immediately preceding
the Purchase Contract Settlement Date pursuant to prior notification to the
Purchase Contract Agent, (iii) has had the Trust Preferred Securities related to
such holder's Purchase Contracts remarketed in the manner described herein in
connection with settling such Purchase Contracts, or (iv) an event described
under "Description of the Purchase Contracts--Termination" has occurred, (A) in
the case of Income PRIDES (unless a Tax Event Redemption has occurred), the
Company will exercise its rights as a secured party to dispose of the Trust
Preferred Securities in accordance with the applicable law, and (B) in the case
of Growth PRIDES or Income PRIDES (in the event that a Tax Event Redemption has
occurred) the principal amount of the related Treasury Securities or the
Treasury Portfolio, as applicable, when paid at maturity, will automatically be
applied to satisfy in full such holder's obligation to purchase Common Stock
under the related Purchase Contracts.
 
     In the event that a holder of either Income PRIDES or Growth PRIDES effects
the early settlement of the related Purchase Contracts through the delivery of
cash in the manner described herein or settles (in the case of Income PRIDES)
the related Purchase Contracts with cash on the Business Day immediately
preceding the Purchase Contract Settlement Date (unless a Tax Event Redemption
has occurred), the related Trust Preferred Securities, Treasury Portfolio or
Treasury Securities, as the case may be, will be released to such holder as
described herein.
 
     The Company will have the right at any time to dissolve the Trust and cause
the Debentures to be distributed to the holders of the Trust Securities. If the
Debentures are distributed to the holders of the Trust Preferred Securities, the
Company will use its best efforts to cause the Debentures to be listed on such
exchange on which the Trust Preferred Securities are then listed, including, if
applicable, the New York Stock Exchange.
 
     The Debentures (and, thus, the Trust Securities) are redeemable at the
option of the Company, in whole but not in part, on not less than 30 days nor
more than 60 days prior notice upon the occurrence and continuation of a Tax
Event (as defined herein) under the circumstances described herein (a "Tax Event
Redemption"). If the Company so redeems all of the Debentures, the Trust must
redeem all of the Trust Securities at a redemption price (the "Redemption
Price") per Trust Security equal to the Redemption Amount (as defined herein)
plus accrued and unpaid distributions (including any deferred distributions)
thereon to the date fixed for redemptions
 
                                       S-5
<PAGE>   50
 
and pay in cash such Redemption Price to the holders of such Trust Preferred
Securities. If such Tax Event Redemption occurs prior to the Purchase Contract
Settlement Date, the Redemption Price payable in liquidation of the Income
PRIDES holders' interests in the Trust will be distributed to the Collateral
Agent, who in turn will apply an amount equal to the Redemption Amount of such
Redemption Price to purchase, on behalf of the holders of Income PRIDES, the
Treasury Portfolio and remit the remaining portion, if any, of such Redemption
Price to the Purchase Contract Agent for payment to the holders of such Income
PRIDES. See "Description of the Debentures--Tax Event Redemption." Such Treasury
Portfolio will be substituted for the Trust Preferred Securities and will be
pledged with the Collateral Agent to secure the Income PRIDES holders'
obligations to purchase the Company's Common Stock under their Purchase
Contracts.

                         PROSPECTUS SUPPLEMENT SUMMARY
 
     The following summary is qualified in its entirety by the more detailed
information and the consolidated financial statements and the related notes
thereto appearing elsewhere in this Prospectus Supplement. On November 17, 1997,
Kennametal Acquisition Corp. ("Acquisition Corp."), a wholly-owned subsidiary of
Kennametal, purchased in accordance with its tender offer (the "Tender Offer")
approximately 98% of the outstanding common stock of Greenfield pursuant to an
Agreement and Plan of Merger dated as of October 10, 1997 (the "Merger
Agreement"), among Kennametal, Greenfield and Acquisition Corp. and, on November
18, 1997, Acquisition Corp. was merged into Greenfield and Greenfield became a
wholly-owned subsidiary of Kennametal. Except as otherwise noted or unless the
context otherwise requires, (i) "fiscal" in connection with a year means the 12
months ended June 30 of the calendar year specified, and (ii) the information in
this Prospectus Supplement assumes no exercise of the Underwriters'
over-allotment option. Unless the context indicates otherwise, any reference in
this Prospectus Supplement to the "Company" or "Kennametal" refers to Kennametal
Inc. and its consolidated subsidiaries other than Greenfield.
 
     This Prospectus Supplement contains certain forward-looking statements (as
such term is defined in the Securities Act) concerning the Company's operations,
performance and financial condition, including, in particular, the likelihood of
the Company's success in integrating the acquisition of Greenfield. These
statements are based upon a number of assumptions and estimates which are
inherently subject to significant uncertainties and contingencies, many of which
are beyond the control of the Company. Actual results may differ materially from
those expressed or implied by such forward-looking statements to the extent that
economic conditions in the United States, Europe and, to a lesser extent, the
Asia Pacific region change from the Company's expectations and to the extent
that the Company does not effectively integrate the acquisition of Greenfield
and achieve expected synergistic benefits.
 
                                  THE COMPANY
 
     The Company is a vertically integrated global manufacturer, marketer and
distributor of a broad range of consumable tools, supplies and services for the
metalworking, mining and highway construction industries. Kennametal specializes
in developing and manufacturing tools utilizing tungsten carbide powder
metallurgy for the three primary metalcutting methods--turning, milling and
drilling. In addition, through its 80%-owned subsidiary, JLK Direct Distribution
Inc. ("JLK"), the Company markets and distributes a broad line of consumable
metalcutting tools, as well as abrasives, machine tool accessories, hand tools,
measuring equipment and other industrial supplies used in the metalworking
industry. The Company is a recognized leader in turning and milling consumable
metalcutting tools and believes it is the largest North American and the second
largest global provider of consumable metalcutting tools and supplies.
Leveraging its expertise in tungsten carbide powder metallurgy, the Company has
developed innovative consumable tools for the mining and construction industries
and believes it is the largest global manufacturer, marketer and distributor of
such tools to these markets.
 
     In November 1997, the Company acquired Greenfield Industries, Inc., the
leading North American manufacturer of drilling and other rotary high-speed
steel consumable metalcutting tools for the metalworking industry. Kennametal
believes that Greenfield's operations strongly complement its core businesses
and that the acquisition of Greenfield, in addition to providing the Company
with opportunities for substantial cost savings, offers significant strategic
benefits, including: (i) providing an important new channel of traditional
industrial distributors through which to sell the Company's products; (ii)
expanding and enhancing the Company's line of drilling products; (iii) allowing
the Company to diversify into new markets such as certain wear products by
leveraging its material science expertise in tungsten carbide powder metallurgy;
and (iv) providing the opportunity to introduce and sell each company's products
into the markets served by the other company.
 
     End users of the Company's metalworking products include manufacturers and
suppliers in the aerospace, automotive, construction and farm machinery,
railroad equipment, power generation and transmission equipment, home appliance,
electrical equipment, and oil field services and gas exploration industries. The
Company markets its products through: a technically skilled direct sales force;
JLK's catalogs, showrooms and other direct marketing efforts; JLK's integrated
industrial supply programs; and, with the acquisition of Greenfield, a network
of traditional industrial distributors. This multi-channel marketing approach
enables the Company to meet the
 
                                       S-7
<PAGE>   52
 
varying needs of metalworking customers of all sizes which range from same-day
ordering and rapid delivery of products to outsourcing the entire procurement
and inventory management process for metalworking and related products. The
Company estimates there are approximately 250,000 metalworking industrial sites
in the United States. The Company's multi-channel distribution network,
comprehensive product offering and global presence allow customers of all sizes
the advantage of a single source of supply for most metalworking needs.
 
     The Company believes five significant trends are currently impacting the
metalworking industry: (i) consolidation of fragmented distribution channels as
customers seek a single source of supply for their metalworking needs; (ii)
increasing demand from large customers to outsource procurement and inventory
management processes through integrated supply programs; (iii) growing demand
for suppliers that can provide a complete selection of tools, supplies and
services globally; (iv) demand for world class capabilities including customer
service, technical application support and information and product technology
while, at the same time, maintaining or reducing costs; and (v) continuing
advances in customers' metalworking manufacturing technology requiring more
technically advanced tools. These factors are resulting in a restructuring and
consolidation in the metalworking industry as tooling manufacturers and
distributors are forced to either become more competitive or seek stronger
partners. The Company's business strategy is designed to capitalize on these and
other trends.
 
BUSINESS STRATEGY
 
     The Company's objective is to become the supplier of first choice of
consumable tools, related supplies, and services to the worldwide metalworking
industry and to other industries which can benefit from tungsten carbide
products. The Company believes its market-leadership position results from the
successful implementation of its business strategy, the major elements of which
include:
 
     - Expanding Customer Base Through Multi-Channel Distribution.  The Company
       seeks to access potential customers through all primary distribution
       channels. The Company serves its traditional base of large and
       medium-sized metalworking customers through a direct sales force. JLK
       direct markets a broad range of tiered ("good," "better" and "best")
       metalworking consumables and other related products targeted at small and
       medium-sized metalworking customers and offers integrated supply programs
       targeted at large industrial metalworking customers. The acquisition of
       Greenfield, which sells its consumable tools, related products and
       services through a network of more than 2,500 traditional industrial
       distributors, provides Kennametal with access to approximately 50% of the
       North American metalworking market.
 
     - Providing Most Complete Product Offering.  The Company seeks to provide
       the most complete and comprehensive product offering in the metalworking
       industry. As a result of various acquisitions and internal development,
       the Company markets and distributes what it believes is one of the
       broadest lines of tools and services typically used by metalworking
       customers. The recent acquisition of Greenfield and its consumable
       high-speed steel rotary cutting tools and related products provides the
       Company with the capability to manufacture all of the major consumable
       tools needed by customers in their metalcutting manufacturing processes.
 
     - Expanding Strong Global Presence.  Kennametal is committed to growing its
       global presence as demonstrated by its position as the second largest
       provider of tools to the European metalworking industry, the world's
       largest metalworking market, and its plans to expand its presence in the
       Asia Pacific region. The Company recently completed construction of a
       cutting tool manufacturing facility in Shanghai, China, for a total
       investment of about $20 million, and has increased to 100% its ownership
       interest in a sales and marketing subsidiary in Japan. The Company also
       has targeted marketing efforts in Eastern Europe and Russia and other
       developing countries.
 
     - Providing Superior Customer Service, Product Availability, and Technical
       Support.  The Company's skills in rapidly filling orders, maintaining
       high levels of product availability and providing technical product
       application support are vital to the ability of its metalworking
       customers to meet their production and delivery schedules in a cost
       effective manner. Kennametal's sophisticated order entry and inventory
       management systems enable the Company to ship more than 90 percent of its
       products from stock. In addition, the Company's technically skilled
       direct sales force of more than 700 persons provide on-site product
       selection and application support to enable customers to optimize their
       metalcutting processes.

       The addition of Greenfield's more than 70 technical specialists broadens
       the Company's technical support capability into high-speed steel drilling
       applications.
 
     - Maintaining Leadership in Product Innovation.  As a result of its
       commitment to research and development, the Company has brought to market
       during the past few years a number of new or improved metalcutting
       products. The exacting requirements of modern high-precision
       metalcutting, along with advances in manufacturing technology, exacting
       manufacturing specifications, and new workpiece materials are driving the
       demand for new and improved consumable tools and systems capable of
       achieving superior technical performance with high and uniform quality.
       The Company believes that its reputation for supplying high quality and
       technologically innovative consumable metalcutting tools and supplies to
       the metalworking industry has been very significant in achieving its
       market position.
 
     - Leveraging Use of Information Technology.  The Company's decision to
       invest nearly $40 million in a business information system utilizing SAP
       R-3 software demonstrates its commitment to the use of information
       technology. This system, which is expected to be fully operational in
       fiscal 1999, will link sales, distribution, manufacturing, purchasing and
       accounting activities at all major sites throughout Kennametal and is
       designed to enhance customer service, operational effectiveness and
       management decision-making.
 
     In addition to the above business strategies, the Company seeks to continue
to improve operating efficiencies as well as to pursue selected acquisitions
that enhance its distribution channels, complement its existing product
offerings and strengthen its geographic presence.
 
                              RECENT DEVELOPMENTS
GREENFIELD ACQUISITION
 
     On November 17, 1997, the Company purchased in the Tender Offer
approximately 98% of Greenfield's common stock and acquired the balance by a
merger on the following day. The total purchase price for the acquisition of
Greenfield (including estimated transaction costs and assumed Greenfield debt
and convertible redeemable preferred securities of approximately $320 million)
is estimated to be $1.0 billion. Greenfield is the largest North American
manufacturer of consumable rotary metalcutting tools as well as a leading
manufacturer of consumable tools and related products, wear products and marine
products.
 
NEW BANK CREDIT FACILITY
 
     In connection with the acquisition of Greenfield, the Company, on November
17, 1997, entered into a $1.4 billion credit agreement with the banks named
therein (the "New Bank Credit Facility") under which, as of November 18, 1997,
the Company had borrowed $500 million in term loans and approximately $300
million in revolving credit loans. The proceeds from the loans were principally
used to pay for the shares of common stock of Greenfield purchased in the Tender
Offer and the merger, to pay transaction costs, to refinance certain
indebtedness of Greenfield and to refinance certain indebtedness of the Company.
 
OTHER ACQUISITIONS
 
     The Company recently acquired Rubig G.m.b.H. of Munich, Germany, Presto
Engineers Cutting Tools Limited of Sheffield, United Kingdom, and Car-Max Tool &
Cutter Sales, Inc. The companies had aggregate annual sales of approximately $46
million in 1996. The Company has also recently entered into an agreement to
acquire GRS Industrial Supply Company, with annual sales of approximately $20
million in 1996.
 
COMMON STOCK OFFERINGS
 
     Concurrently with the Offering, the Company is undertaking the Common Stock
Offerings of an aggregate of        shares. The Offering is not, however,
conditioned upon the consummation of the Common Stock Offerings. The net
proceeds to the Company from the Common Stock Offerings will be used to prepay
term loans under the New Bank Credit Facility.

                                 described herein and (ii) the Company will pay
                                 the holder of the Contract Adjustment Payments,
                                 if any, and (b) a 1/20 undivided beneficial
                                 ownership interest in a related Treasury

                                 Settlement Date, a holder of Growth PRIDES will
                                 have the right to subsequently recreate Income
                                 PRIDES by delivering 20 Growth PRIDES to the
                                 Purchase Contract Agent plus 20 Trust Preferred

                                 for 20 Income PRIDES and the release of the
                                 related Treasury Security to such holder;
                                 provided, however, if a Tax Event Redemption
                                 has occurred prior to the Purchase Contract
                                 Settlement Date and the Treasury Portfolio has
                                 become a component of the Income PRIDES,
                                 holders of Growth PRIDES may make such
                                 substitution only in integral multiples of
                                 8,000 Growth PRIDES (but using the Treasury

                                 second Business Day immediately preceding the
                                 Purchase Contract Settlement Date. Such Trust

                                 as the case may be, will be pledged with the
                                 Collateral Agent to secure the holder's
                                 obligation to purchase Common Stock under the
                                 related Purchase Contracts. See "Description of

Current Payments..............   Holders of Income PRIDES will be entitled to
                                 receive aggregate cash distributions at a rate
                                 of   % of the Stated Amount per annum from and
                                 after          , 1998, payable quarterly in
                                 arrears, consisting of cumulative cash
                                 distributions on the related Trust Preferred
                                 Securities or the Treasury Portfolio, as
                                 applicable, payable at the rate of   % of the
                                 Stated Amount per annum, and Contract
                                 Adjustment Payments, payable by the Company at
                                 the rate of   % of the Stated Amount per annum;
                                 provided that if such rate is 0%, then the
                                 Company will not make any Contract Adjustment
                                 Payments, subject (in the case of such
                                 distributions on the Trust Preferred Securities
                                 and of the Contract Adjustment Payments to the
                                 Company's right to defer the payment of such
                                 amounts. The ability of the Trust to make the
                                 quarterly distributions on the related Trust
                                 Preferred Securities will be solely dependent
                                 upon the receipt of corresponding interest
                                 payments from the Company on the Debentures.
 
                                 In the event that a holder of Income PRIDES
                                 substitutes Treasury Securities for the related
                                 Trust Preferred Securities or the Treasury
                                 Portfolio, as the case may be, such holder
                                 would receive on the resulting Growth PRIDES
                                 only the quarterly distributions of Contract
                                 Adjustment Payments, if any, subject to the
                                 Company's rights of deferral described herein.

                                 would continue to accrue on the related
                                 Treasury Securities. See "Risk Factors--Right
                                 to Defer Current Payments."
 
                                 The Company's obligations with respect to the
                                 Debentures will be senior and unsecured and
                                 will rank pari passu in right of payment with
                                 all other senior unsecured obligations of the
                                 Company. The Contract Adjustment Payments, if
                                 any, will be subordinated and junior in right
                                 of payment to the Senior Indebtedness. If a Tax
                                 Event Redemption has occurred as described
                                 herein and the Treasury Portfolio has become a
                                 component of the Income PRIDES, quarterly
                                 distributions on the Treasury Portfolio, as a
                                 portion of the cumulative quarterly
                                 distribution to the holders of Income PRIDES,
                                 will not be deferred.
 
Contract Adjustment
Payments......................   Contract Adjustment Payments will be fixed at a
                                 rate per annum of   % of the Stated Amount per
                                 Purchase Contract, provided that if such rate
                                 is 0%, then the Company will not make any
                                 Contract Adjustment Payments. Contract
                                 Adjustment Payments will be specified as a
                                 positive component of the distributions on the
                                 Income PRIDES only if and to the extent that
                                 the rate of distributions on the Trust
                                 Preferred Securities, as determined on the date
                                 on which the Income PRIDES are priced for sale,
                                 is less than the aggregate distribution rate
                                 required on such date for the offer and sale of
                                 the Income PRIDES at the price to public
                                 specified on the cover page of this Prospectus
                                 Supplement. Accordingly, the final Prospectus
                                 Supplement will indicate whether and to what
                                 extent Contract Adjustment Payments will be
                                 required to be made by the Company. See
                                 "Description of the Purchase
                                 Contracts--Contract Adjustment Payments."
 
Option to Extend Distribution
Payment Periods...............   The Company has the right at any time, and from
                                 time to time, limited to a period not extending
                                 beyond the maturity date of the Debentures, to
                                 defer the interest payments due on the
                                 Debentures. As a consequence of such deferral,
                                 quarterly distributions to holders of Income
                                 PRIDES (or any Trust Preferred Securities
                                 outstanding after the Purchase Contract
                                 Settlement Date or after a substitution of
                                 collateral resulting in the creation of Growth
                                 PRIDES) would be deferred (but despite such
                                 deferral, would continue to accumulate
                                 quarterly and would accrue interest thereon
                                 compounded quarterly at the rate of   % per
                                 annum through and including February 15, 2001,
                                 and at the Reset Rate thereafter). The Company
                                 also has the right to defer the payment of
                                 Contract Adjustment Payments, if any, on the
                                 related Purchase Contracts until no later than
                                 the Purchase Contract Settlement Date; however,
                                 such deferred Contract Adjustment Payments, if
                                 any, will bear additional Contract Adjustment
                                 Payments at the rate of   % per annum (such
                                 deferred Contract Adjustment Payments together
                                 with the additional Contract Adjustment
                                 Payments shall be referred to as the "Deferred
                                 Contract Adjustment Payments"). See
                                 "Description of the Purchase
                                 Contracts--Contract Adjustment Payments." If
                                 interest payments on the Debentures or the
                                 Contract Adjustment Payments, if any, are
                                 deferred, the Company has agreed, among other
                                 things, not to declare or pay any dividend on
                                 or repurchase its capital stock during the
                                 period of such deferral. If a Tax Event
                                 Redemption has occurred and the Treasury

                                 PRIDES will not be deferred.
 
                                 In the event that the Company elects to defer
                                 the payment of Contract Adjustment Payments, if
                                 any, on the related Purchase Contracts until
                                 the Purchase Contract Settlement Date, each
                                 holder of the related Income PRIDES or Growth
                                 PRIDES will receive on the Purchase Contract
                                 Settlement Date in respect of such Deferred

                                 Agent"), and subject to the terms of a
                                 Remarketing Underwriting Agreement to be dated

                                 Securities, the Remarketing Agent will remit
                                 the remaining portion of the proceeds, if any,
                                 for the benefit of such Income PRIDES holder.

                                 reasonable efforts, the Remarketing Agent
                                 cannot remarket the related Trust Preferred
                                 Securities of such holders of Income PRIDES at
                                 a price not less than 100% of the aggregate

                                 such disposition, such Income PRIDES holders'
                                 obligation to purchase Common Stock under the
                                 related Purchase Contracts, provided, that if
                                 the Company exercises such rights as a secured
                                 creditor, with respect to such Trust Preferred
                                 Securities, any accrued and unpaid

                                 to the holder of record (immediately prior to
                                 such Failed Remarketing) of such Trust

                                 Date (the "Settlement Rate") will be calculated
                                 as follows (subject to adjustment under certain
                                 circumstances): (a) if the Applicable Market
                                 Value is equal to or greater than $
                                 (the "Threshold Appreciation Price," which is
                                 approximately   % above the last reported sale
                                 price of the Common Stock set forth on the

                                 (the "Reference Price")), the Settlement Rate
                                 (which will be equal to the Stated Amount
                                 divided by the Threshold Appreciation Price)
                                 will be        ; accordingly, if, between the
                                 date of this Prospectus Supplement and the
                                 period during which the Applicable Market Value
                                 is measured, the market price for the Common
                                 Stock increases to an amount that is higher
                                 than the Threshold Appreciation Price, the
                                 aggregate market value of the shares of Common
                                 Stock issued upon settlement of each Purchase
                                 Contract (assuming that such market value is
                                 the same as the Applicable Market Value of such
                                 Common Stock) will be higher than the Stated
                                 Amount, and if such market price is equal to
                                 the Threshold Appreciation Price, the aggregate
                                 market value of such shares (assuming that such
                                 market value is the same as the Applicable
                                 Market Value of such Common Stock) will be
                                 equal to the Stated Amount; (b) if the

                                 Threshold Appreciation Price but greater than
                                 the Reference Price, the Settlement Rate will
                                 be equal to the Stated Amount divided by the
                                 Applicable Market Value; accordingly, if the
                                 market price for the Common Stock increases
                                 between the date of this Prospectus Supplement
                                 and the period during which the Applicable
                                 Market Value is measured but such market price
                                 is less than the Threshold Appreciation Price,
                                 the aggregate market value of the shares of
                                 Common Stock issued upon settlement of each

                                 value is the same as the Applicable Market
                                 Value of such Common Stock) will be equal to
                                 the Stated Amount; and (c) if the Applicable
                                 Market Value is less than or equal to the
                                 Reference Price, the Settlement Rate (which

                                 occurs, the holders of the Trust Preferred
                                 Securities will be required to accrue interest

                                 the Debentures are deferred, interest will

Distribution of Debentures....   In certain circumstances involving an
                                 Investment Company Event, the Trust would be
                                 dissolved, with the result that, after
                                 satisfaction of liabilities to creditors of the
                                 Trust, if any, Debentures with an aggregate
                                 principal amount equal to the aggregate stated
                                 liquidation amount of the Trust Preferred
                                 Securities would be distributed to the holders
                                 of the Trust Preferred Securities on a pro rata
                                 basis. In such event (unless a Tax Event
                                 Redemption has occurred), Trust Preferred
                                 Securities constituting a component of the
                                 Income PRIDES would be substituted for
                                 Debentures with a principal amount per
                                 Debenture equal to the stated liquidation
                                 amount per Trust Preferred Security. See
                                 "Description of the Trust Preferred
                                 Securities--Distribution on the Debentures."
 
Tax Event Redemption..........   The Debentures (and, thus, the Trust
                                 Securities) are redeemable, at the option of
                                 the Company, on not less than 30 days or more
                                 than 60 days prior written notice in whole but
                                 not in part upon the occurrence and
                                 continuation of a Tax Event under the
                                 circumstances described herein at a Redemption
                                 Price equal to, for each Debenture, the
                                 Redemption Amount. See "Description of the
                                 Debentures--Tax Event Redemption." If the
                                 Company so redeems all of the Debentures the
                                 Trust must redeem all of the Trust Securities
                                 and pay in cash such Redemption Price to the
                                 holders of such Trust Securities. If such Tax
                                 Event Redemption occurs prior to the Purchase
                                 Contract Settlement Date, the Redemption Price
                                 payable, in liquidation of any Income PRIDES
                                 holders' interest in the Trust, will be
                                 distributed to the Collateral Agent, who in
                                 turn will apply an amount equal to the
                                 Redemption Amount of such Redemption Price to
                                 purchase on behalf of the holders of Income
                                 PRIDES, the Treasury Portfolio and remit the
                                 remaining portion of such Redemption Price to
                                 the Purchase Contract Agent for payment to
                                 holders of such Income PRIDES. The Treasury
                                 Portfolio will be substituted for the Trust
                                 Preferred Securities and will be pledged with
                                 the Collateral Agent to secure such Income
                                 PRIDES holders' obligations to purchase the
                                 Company's Common Stock under their Purchase
                                 Contracts.
 
                                 Other than Tax Event Redemption, the Company
                                 will not have the ability to redeem the
                                 Debentures prior to their stated maturity date.
                                 See "Description of the Debentures--Tax Event
                                 Redemption".
 
Guarantee.....................   The Company will irrevocably and
                                 unconditionally guarantee (the "Guarantee"),
                                 generally on a senior unsecured basis, the
                                 payment in full of (i) distributions on the
                                 Trust Preferred Securities to the extent the
                                 Trust has funds available therefor, (ii) the
                                 redemption price of Trust Preferred Securities
                                 in respect of which the related Debentures have
                                 been repurchased by the Company on the Purchase
                                 Contract Settlement Date, to the extent the
                                 Trust has funds available therefor, and (iii)
                                 generally, the liquidation amount of the Trust
                                 Preferred Securities or the Redemption Price
                                 upon a Tax Event Redemption, to the extent the
                                 Trust has assets available for distribution to
                                 holders of Trust Preferred Securities in the
                                 event of a dissolution of the Trust. The
                                 Guarantee will be a senior unsecured obligation
                                 of the Company and will rank pari passu with
                                 all of the Company's other senior unsecured
                                 obligations. See "Description of the
                                 Guarantee."

                                 Debentures will mature on February 16, 2003,
                                 and will bear, initially, interest at the rate
                                 of   % per annum, payable quarterly in arrears
                                 on each February 16, May 16, August 16 and

                                 distribution rate on the Trust Preferred
                                 Securities, that remain outstanding after
                                 February 16, 2003, payable on and after
                                 February 16, 2003 will be reset on the third
                                 Business Day immediately preceding February 16,
                                 2003 to the Reset Rate determined by the Reset
                                 Agent. See "Description of
                                 Debentures--Interest." Interest payments on the
                                 Debentures may be deferred from time to time by
                                 the Company for successive Extension Periods
                                 not extending, in the aggregate, beyond the
                                 stated maturity date of the Debentures. During
                                 any Extension Period, interest at the rate of
                                   % per annum through and including February
                                 16, 2003, and at the Reset Rate thereafter
                                 would continue to accrue and compound
                                 quarterly. Upon the termination of any
                                 Extension Period and the payment of all amounts
                                 then due, the Company may commence a new
                                 Extension Period, provided such new Extension
                                 Period does not extend beyond the stated
                                 maturity date of the Debentures. No interest
                                 shall be due during an Extension Period until
                                 the end of such period. During an Extension
                                 Period, the Company will be prohibited from
                                 paying dividends on or purchasing any of its
                                 capital stock and making certain other
                                 restricted payments until quarterly interest
                                 payments are resumed and all amounts then due
                                 on the Debentures are paid. The Debentures will
                                 be senior unsecured obligations of the Company
                                 and will rank pari passu with all of the
                                 Company's other senior unsecured obligations.
                                 See "Description of the Debentures."
 
Federal Income Tax
Consequences..................   Provided the Company does not exercise its
                                 right to defer interest on the Debentures, a
                                 beneficial owner of Income PRIDES and Trust
                                 Preferred Securities will include in gross
                                 income its pro rata share of the stated
                                 interest on the Debentures when such interest
                                 income is paid or accrued in accordance with
                                 its regular method of tax accounting. The
                                 Company intends to report the Contract
                                 Adjustment Payments as income to holders of
                                 Income PRIDES and Growth PRIDES, but holders
                                 should consult their tax advisors concerning
                                 the possibility that the Contract Adjustment
                                 Payments may be treated as loans, purchase
                                 price adjustments, rebates or option premiums
                                 rather than being includible in income on a
                                 current basis. Holders of Growth PRIDES will be
                                 required to include in gross income their
                                 allocable share of any original issue discount
                                 ("OID") or market discount, or amortize their
                                 allocable share of any bond premium otherwise
                                 includible or deductible, respectively, with
                                 respect to the Treasury Securities posted with
                                 the Collateral Agent. If a Tax Event Redemption
                                 has occurred, a beneficial owner of Income
                                 PRIDES will be required to include in gross
                                 income its allocable share of OID on the
                                 Treasury Portfolio as it accrues on a constant
                                 yield to maturity basis. See "Certain Federal

                                  RISK FACTORS
 
     Prospective investors should consider, in addition to the other information
set forth elsewhere in this Prospectus Supplement, the following matters in
evaluating the Company and the Income PRIDES offered hereby.
 
INVESTMENT IN FELINE PRIDES REQUIRES HOLDERS TO PURCHASE COMMON STOCK; RISK OF
DECLINE IN EQUITY VALUE
 
     Although holders of the FELINE PRIDES will be the beneficial owners of the
related Trust Preferred Securities or Treasury Securities, as the case may be,
prior to the Purchase Contract Settlement Date, unless a holder of FELINE PRIDES
settles the related Purchase Contracts through the delivery of cash to the
Purchase Contract Agent in the manner described below or the Purchase Contracts
are terminated (upon the occurrence of certain events of bankruptcy, insolvency
or reorganization with respect to the Company), the proceeds of the repurchase
by the Company of the related Subordinated Debt Securities or the principal of
the related Treasury Securities, when paid at maturity, as the case may be, will
automatically be applied to the purchase of a specified number of shares of
Common Stock on behalf of such holder. Thus, unless a holder of Income PRIDES
has cash settled, following the Purchase Contract Settlement Date, holders will
own shares of Common Stock rather than a beneficial interest in Trust Preferred
Securities. See "Description of the Purchase Contracts--General." There can be
no assurance that the market value of the Common Stock receivable by the holder
on the Purchase Contract Settlement Date will be equal to or greater than the
Stated Amount of the FELINE PRIDES held by such holder. If the Applicable Market
Value of the Common Stock is less than the Reference Price, the aggregate market
value of the Common Stock issued to the holder in settlement of each Purchase
Contract on the Purchase Contract Settlement Date (assuming that such market
value is the same as the Applicable Market Value of such Common Stock) will be
less than the Stated Amount paid for the FELINE PRIDES and the Market Value per
share of such Common Stock will be less than the effective price per share paid
by each holder for such Common Stock, in which case an investment in the
Securities will result in a loss. Accordingly, a holder of the FELINE PRIDES
assumes the risk that the market value of the Common Stock may decline, and that
such decline could be substantial.
 
LIMITATIONS ON OPPORTUNITY FOR EQUITY APPRECIATION
 
     The opportunity for equity appreciation afforded by an investment in the
FELINE PRIDES is less than the opportunity for equity appreciation afforded by a
direct investment in the Common Stock because the market value of the Common
Stock to be received by a holder of Purchase Contracts on the Purchase Contract
Settlement Date (assuming that such market value is the same as the Applicable
Market Value of such Common Stock) will only exceed the Stated Amount if the
Applicable Market Value of the Common Stock exceeds the Threshold Appreciation
Price (which represents an appreciation of     % over the Reference Price).
Moreover, in such event, holders of the FELINE PRIDES would receive on the
Purchase Contract Settlement Date only     % (the percentage equal to the
Reference Price divided by the Threshold Appreciation Price) of the shares of
Common Stock that such holders would have received if they had made a direct
investment in the Common Stock on the date hereof, and therefore would receive
on the Purchase Contract Settlement Date     % of the appreciation in the value
of the Common Stock in excess of the Threshold Appreciation Price through such
date.
 
FACTORS AFFECTING TRADING PRICES
 
     The trading prices of the Income PRIDES and the Growth PRIDES in the
secondary market will be directly affected by the trading prices of the Common
Stock in the secondary market, the general level of interest rates and the
credit quality of the Company. It is impossible to predict whether the price of
Common Stock or interest rates generally will rise or fall. Trading prices of
Common Stock will be influenced by Kennametal's operating results and prospects
and by economic, financial and other factors and market conditions that can
affect the capital markets generally, including the level of, and fluctuations
in, the trading prices of stocks generally and sales of substantial amounts of
Common Stock in the market subsequent to the offering of the Securities or the
perception that such sales could occur. Fluctuations in interest rates may give
rise to opportunities for arbitrage based upon changes in the relative value of
the Common Stock underlying the Purchase Contracts and of the other components
of the FELINE PRIDES. Any such arbitrage could, in turn, affect the trading
prices of the Income PRIDES, Growth PRIDES, Trust Preferred Securities and
Common Stock.
 
                                      S-25
<PAGE>   70
 
VOTING RIGHTS
 
     Holders of Trust Preferred Securities will not be entitled to vote to
appoint, remove or replace or to increase or decrease the number of Kennametal
Trustees, and generally will have no voting rights except in the limited
circumstances described under "Description of the Trust Preferred
Securities--Voting Rights." Holders of FELINE PRIDES will not be entitled to any
rights with respect to the Common Stock (including, without limitation, voting
rights and rights to receive any dividends or other distributions in respect
thereof) unless and until such time as the Company shall have delivered shares
of Common Stock for FELINE PRIDES on the Purchase Contract Settlement Date or as
a result of Early Settlement, as the case may be, and unless the applicable
record date, if any, for the exercise of such rights occurs after such date. For
example, in the event that an amendment is proposed to the Amended and Restated
Articles of Incorporation (the "Restated Articles") or Amended and Restated
By-Laws (the "Restated By-Laws") of the Company and the record date for
determining the stockholders of record entitled to vote on such amendment occurs
prior to such delivery, holders of FELINE PRIDES will not be entitled to vote on
such amendment.
 
DILUTION OF COMMON STOCK
 
     The number of shares of Common Stock that holders of the FELINE PRIDES are
entitled to receive on the Purchase Contract Settlement Date is subject to
adjustment for certain events arising from stock splits and combinations, stock
dividends and certain other actions of Kennametal that modify its capital
structure. See "Description of the Purchase Contracts--Anti-Dilution
Adjustments." Such number of shares of Common Stock to be received by such
holders on the Purchase Contract Settlement Date will not be adjusted for other
events, such as offerings of Common Stock for cash or in connection with
acquisitions. Kennametal is not restricted from issuing additional shares of
Common Stock during the term of either the Purchase Contracts or the Trust
Preferred Securities. Additional issuances may materially and adversely affect
the price of the Common Stock and, because of the relationship of the number of
shares to be received on the Purchase Contract Settlement Date to the price of
the Common Stock, such other events may adversely affect the trading price of
the Income PRIDES or Growth PRIDES.
 
POSSIBLE ILLIQUIDITY OF THE SECONDARY MARKET
 
     It is not possible to predict how the Income PRIDES, the Growth PRIDES or
the Trust Preferred Securities will trade in the secondary market or whether the
market for any such securities will be liquid or illiquid. The Income PRIDES and
the Growth PRIDES are novel securities and there is currently no secondary
market for either the Income PRIDES or Growth PRIDES. Application has been made
to list the Income PRIDES on the NYSE. The Growth PRIDES and the Trust Preferred
Securities will initially not be listed or traded on any securities exchange.
The Company and the Trust have been advised by the Representatives that they
presently intend to make a market for the Growth PRIDES and the Trust Preferred
Securities; however, they are not obligated to do so and any market making may
be discontinued at any time. There can be no assurance as to the liquidity of
any such market that may develop for the Income PRIDES, the Growth PRIDES or the
Trust Preferred Securities, the ability of holders to sell such securities, the
price at which holders would be able to sell such securities or whether a
trading market, if it develops, will continue. In addition, in the event that
holders of Income PRIDES were to substitute Treasury Securities for the Trust
Preferred Securities, thereby converting their Income PRIDES to Growth PRIDES,
the liquidity of Income PRIDES could be adversely affected. There can be no
assurance that the Income PRIDES will not be delisted from the NYSE or that
trading in the Income PRIDES will not be suspended as a result of the election
by holders to create Growth PRIDES through the substitution of collateral, which
could cause the number of holders of Income PRIDES to fall below the minimum
requirements for listing the securities on the NYSE.
 
PLEDGED SECURITIES ENCUMBERED
 
     Although holders of FELINE PRIDES will be beneficial owners of the
underlying Trust Preferred Securities or the Treasury Securities (together, the
"Pledged Securities"), as the case may be, those Pledged Securities will be
pledged with the Collateral Agent to secure the obligations of the holders under
the Purchase Contracts. Thus, rights of the holders to their Pledged Securities
will be subject to the Company's security interest. Additionally,
notwithstanding the automatic termination of the Purchase Contracts, in the
event that the Company becomes the
 
                                      S-26
<PAGE>   71
 
subject of a case under the Bankruptcy Code, the delivery of the Pledged
Securities to holders of the Securities may be delayed by the imposition of the
automatic stay of Section 362 of the Bankruptcy Code.
 
INVESTMENT COMPANY EVENT DISTRIBUTION
 
     Upon the occurrence of an Investment Company Event, the Trust will be
dissolved (except in the limited circumstances described in the following
sentence) with the result that Debentures with an aggregate principal amount
equal to the aggregate stated liquidation amount of the Trust Preferred
Securities would be distributed to the holders of the Trust Preferred Securities
on a pro rata basis. Such dissolution and distribution shall be conditioned on
the Company being unable to avoid such Investment Company Event within a 90 day
period by taking some ministerial action or pursuing some other reasonable
measure that will have no adverse effect on the Trust, the Company or the
holders of the Trust Preferred Securities, and will involve no material cost. In
addition, the Company will have the right at any time to dissolve the Trust. See
"Description of the Trust Preferred Securities--Distribution of the Debentures."
 
     There can be no assurance as to the impact on the market prices for Income
PRIDES of a distribution of the Debentures in exchange for Trust Preferred
Securities upon a dissolution of the Trust. Because Income PRIDES will consist
of Debentures and related Purchase Contracts upon the occurrence of the
dissolution of the Trust as a result of an Investment Company Event or
otherwise, prospective purchasers of Income PRIDES are also making an investment
decision with regard to the Debentures and should carefully review all the
information regarding the Debentures contained herein. See "Description of the
Trust Preferred Securities--Distribution of the Debentures" and "Description of
the Debentures--General."
 
TAX EVENT REDEMPTION
 
     The Debentures (and, thus, the Trust Securities) are redeemable, at the
option of the Company, on not less than 30 days or more than 60 days prior
written notice, in whole but not in part, at any time upon the occurrence and
continuation of a Tax Event under the circumstances described herein at a
Redemption Price equal to, for each Debenture, the Redemption Amount. See
"Description of the Debentures--Tax Event Redemption." If the Company so redeems
all of the Debentures, the Trust must redeem all of the Trust Securities plus
accrued and unpaid distributions (including deferred distributions) and pay in
cash such Redemption Price to the holder of such Trust Securities. If such Tax
Event Redemption occurs prior to the Purchase Contract Settlement Date, the
Redemption Price payable, in liquidation of the Income PRIDES holders' interest
in the Trust, will be distributed to the Collateral Agent, who in turn will
apply an amount equal to the Redemption Amount of such Redemption Price to
purchase on behalf of the holders of Income PRIDES, the Treasury Portfolio and
remit the remaining portion of such Redemption Price to the Purchase Contract
Agent for payment to holders of such Income PRIDES. Holders of Trust Preferred
Securities, not held in the form of Income PRIDES, will receive redemption
payments. The Treasury Portfolio will be pledged with the Collateral Agent to
secure such Income PRIDES holders' obligations to purchase the Company's Common
Stock under their Purchase Contracts. There can be no assurance as to the impact
on the market prices for the Income PRIDES of the pledging of the Treasury
Portfolio as collateral in replacement of any Trust Preferred Securities so
redeemed. A Tax Event Redemption will be a taxable event to the beneficial
owners of the Trust Preferred Securities. See "Certain Federal Income Tax
Consequences--Tax Event Redemption."
 
RIGHT TO DEFER CURRENT PAYMENTS
 
     The Company may, at its option, defer the payment of Contract Adjustment
Payments, if any, on the Purchase Contracts until the Purchase Contract
Settlement Date. However, deferred installments of Contract Adjustment Payments,
if any, will bear Deferred Contract Adjustment Payments at the rate of     % per
annum (compounding on each succeeding Payment Date) until paid. If the Purchase
Contracts are settled early or terminated (upon the occurrence of certain events
of bankruptcy, insolvency or reorganization with respect to the Company), the
right to receive Contract Adjustment Payments (other than any accrued but unpaid
Contract Adjustment Payments that have not been deferred), if any, and Deferred
Contract Adjustment Payments, if any, will also terminate.
 
     In the event that the Company elects to defer the payment of any Contract
Adjustment Payments on the Purchase Contracts until the Purchase Contract
Settlement Date, each holder of Purchase Contracts will receive
 
                                      S-27
<PAGE>   72
 
on the Purchase Contract Settlement Date in respect of the Deferred Contract
Adjustment Payments, in lieu of a cash payment, a number of shares of Common
Stock equal to (x) the aggregate amount of Deferred Contract Adjustment Payments
payable to such holder divided by (y) the Applicable Market Value. See
"Description of the Purchase Contracts--Contract Adjustment Payments."
 
     The Company also will have the right under the Indenture to defer payments
of interest on the Debentures by extending the interest payment period at any
time, and from time to time, on the Debentures. As a consequence of such an
extension, quarterly distributions on the Trust Preferred Securities, held
either as a component of the Income PRIDES or held separately, would be deferred
(but despite such deferrals would accrue interest at a rate of     % per annum
through and including February 16, 2001, and at the Reset Rate thereafter,
compounded on a quarterly basis) by the Trust during any such Extension Period.
Such right to extend the interest payment period for the Debentures will be
limited such that an Extension Period may not extend beyond the maturity date of
the Debentures. During any such Extension Period, (a) the Company shall not
declare or pay dividends on, make distributions with respect to, or redeem,
purchase or acquire, or make a liquidation payment with respect to, any of its
capital stock (other than (i) purchases or acquisitions of capital stock of the
Company in connection with the satisfaction by the Company of its obligations
under any employee benefit plans or the satisfaction by the Company of its
obligations pursuant to any contract or security outstanding on the date of such
event requiring the Company to purchase capital stock of the Company, (ii) as a
result of a reclassification of the Company's capital stock or the exchange or
conversion of one class or series of the Company's capital stock for another
class or series of the Company's capital stock, (iii) the purchase of fractional
interests in shares of the Company's capital stock pursuant to the conversion or
exchange provisions of such capital stock or the security being converted or
exchanged, (iv) dividends or distributions in capital stock of the Company and
(v) redemptions or repurchases of any rights pursuant to the Rights Agreement,
as amended, between the Company and Mellon Bank, N.A., as Rights Agent (the
"Rights Agreement"), or any successor to the Rights Agreement, and the
declaration thereunder of a dividend of rights in the future), (b) the Company
shall not make any payment of interest, principal or premium, if any, on or
repay, repurchase or redeem any debt securities issued by the Company that rank
junior to the Debentures and (c) the Company shall not make any guarantee
payments with respect to the foregoing (other than payments pursuant to the
Guarantee or the Common Securities Guarantee (as defined herein)). Prior to the
termination of any such Extension Period, the Company may further extend the
interest payment period; provided, that such Extension Period may not extend
beyond the Stated Maturity of the Debentures. Upon the termination of any
Extension Period and the payment of all amounts then due, the Company may
commence a new Extension Period, subject to the above requirements. See
"Description of the Trust Preferred Securities--Distributions" and "Description
of the Debentures--Option to Extend Interest Payment Period."
 
     The Company believes, and intends to take the position, that as of the
issue date of the Debentures, the likelihood that it will exercise its right to
defer payments of stated interest on the Debentures is remote and that,
therefore, the Debentures should not be considered to be issued with OID as a
result of the Company's right to defer payments of stated interest on the
Debentures unless it actually exercises such deferral right. There is no
assurance that the Internal Revenue Service will agree with such position. See
"Certain Federal Income Tax Consequences--Interest Income and Original Issue
Discount."
 
     Should the Company exercise its right to defer payments of interest by
extending the interest payment period, each beneficial owner of Trust Preferred
Securities held either as a component of the Income PRIDES or held separately
would be required to include such beneficial owner's share of the stated
interest on the Trust Preferred Securities in gross income, as OID, on a daily
economic accrual basis, regardless of its method of tax accounting and in
advance of receipt of the cash attributable to such income. As a result, each
such beneficial owner of Trust Preferred Securities would recognize income for
United States federal income tax purposes in advance of the receipt of cash
attributable to such income, and would not receive the cash from the Trust
related to such income if such holder disposes of its Trust Preferred Securities
prior to the record date for the date on which distributions of such amounts are
made. See "Certain Federal Income Tax Consequences--Interest Income and Original
Issue Discount." The Company has no current intention of exercising its right to
defer payments of interest by extending the interest payment period on the
Debentures. However, should the Company determine to exercise such right in the
future, the market price of the Trust Preferred Securities is likely to be
affected. A holder that disposes of its Trust Preferred Securities during an
Extension Period, therefore, might not receive the
 
                                      S-28
<PAGE>   73
 
same return on its investment as a holder that continues to hold its Trust
Preferred Securities. In addition, as a result of the existence of the Company's
right to defer interest payments, the market price of the Trust Preferred
Securities (which represent an undivided beneficial interest in the assets of
the Trust) may be more volatile than the market price of other securities that
are not subject to such deferral. See "Certain Federal Income Tax
Consequences--Interest Income and Original Issue Discount."
 
UNITED STATES FEDERAL INCOME TAX CONSEQUENCES
 
     No statutory, judicial or administrative authority directly addresses the
treatment of the FELINE PRIDES or instruments similar to the FELINE PRIDES for
United States federal income tax purposes. As a result, certain United States
federal income tax consequences of the purchase, ownership and disposition of
FELINE PRIDES are not entirely clear. See "Certain Federal Income Tax
Consequences."
 
PURCHASE CONTRACT AGREEMENT NOT QUALIFIED UNDER TRUST INDENTURE ACT; LIMITED
OBLIGATIONS OF PURCHASE CONTRACT AGENT
 
     Although the Trust Preferred Securities constituting a part of the Income
PRIDES will be issued pursuant to the Declaration, which will be qualified under
the Trust Indenture Act, the Purchase Contract Agreement will not be qualified
as an indenture under the Trust Indenture Act and the Purchase Contract Agent
will not be required to qualify as a trustee thereunder. Accordingly, holders of
FELINE PRIDES will not have the benefit of the protections of the Trust
Indenture Act. The protections generally afforded the holder of a security
issued under an indenture that has been qualified under the Trust Indenture Act
include disqualification of the indenture trustee for "conflicting interests" as
defined under the Trust Indenture Act, provisions preventing a trustee that is
also a creditor of the issuer from improving its own credit position at the
expense of the security holders immediately prior to or after a default under
such indenture and the requirement that the indenture trustee deliver reports at
least annually with respect to certain matters concerning the indenture trustee
and the securities. Under the terms of the Purchase Contract Agreement, the
Purchase Contract Agent will have only limited obligations to the holders of
FELINE PRIDES. See "Certain Provisions of the Purchase Contract Agreement and
the Pledge Agreement--Information Concerning the Purchase Contract Agent."
 
RIGHTS UNDER THE GUARANTEE
 
     The Guarantee will be qualified as an indenture under the Trust Indenture
Act. The Guarantee Trustee will act as indenture trustee under the Guarantee for
the purposes of compliance with the provisions of the Trust Indenture Act. The
Guarantee Trustee will hold the Guarantee for the benefit of the holders of the
Trust Preferred Securities.
 
     The Guarantee guarantees to the holders of the Trust Preferred Securities,
generally on a senior basis, the payment of (i) any accrued and unpaid
distributions that are required to be paid on the Trust Preferred Securities, to
the extent the Trust has funds available therefor, (ii) the redemption price,
including all accumulated and unpaid distributions to the date of redemption, of
Trust Preferred Securities in respect of which the related Debentures have been
repurchased by the Company on the Purchase Contract Settlement Date, to the
extent the Trust has funds available therefor, and (iii) upon a voluntary or
involuntary dissolution of the Trust (other than in connection with the
distribution of Debentures to the holders of Trust Preferred Securities), the
lesser of (a) the aggregate of the liquidation amount and all accrued and unpaid
distributions on the Trust Preferred Securities to the date of payment to the
extent the Trust has funds available therefor or (b) the amount of assets of the
Trust remaining available for distribution to holders of the Trust Preferred
Securities in liquidation of the Trust. The holders of a majority in liquidation
amount of the Trust Preferred Securities will have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
Guarantee Trustee or to direct the exercise of any trust or power conferred upon
the Guarantee Trustee under the Guarantee. Notwithstanding the foregoing, any
holder of Trust Preferred Securities may institute a legal proceeding directly
against the Company to enforce such holder's rights under the Guarantee without
first instituting a legal proceeding against the Trust, the Guarantee Trustee or
any other person or entity. If the Company were to default on its obligation to
pay amounts payable on the Debentures or otherwise, the Trust would lack funds
for the payment of distributions or amounts payable on redemption of the Trust
Preferred Securities or otherwise, and, in such event, holders of the Trust
Preferred Securities would not be able to rely upon the Guarantee for payment of
such amounts. Instead,
 
                                      S-29
<PAGE>   74
 
holders of the Trust Preferred Securities would rely on the enforcement (1) by
the Institutional Trustee of its rights as registered holder of the Debentures
against the Company pursuant to the terms of the Indenture and the Debentures or
(2) by such holder of the Institutional Trustee's or such holder's own rights
against the Company to enforce payments on the Debentures. See "--Enforcement of
Certain Rights by Holders of Trust Preferred Securities," "Description of the
Debentures" and "Description of the Guarantee." The Declaration provides that
each holder of Trust Preferred Securities, by acceptance thereof, agrees to the
provisions of the Guarantee, including the subordination provisions thereof, and
the Indenture.
 
ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF TRUST PREFERRED SECURITIES
 
     If a Declaration Event of Default (as defined herein) occurs and is
continuing, the holders of Trust Preferred Securities would rely on the
enforcement by the Institutional Trustee of its rights as registered holder of
the Debentures against the Company. In addition, the holders of a majority in
liquidation amount of the Trust Preferred Securities will have the right to
direct the time, method, and place of conducting any proceeding for any remedy
available to the Institutional Trustee or to direct the exercise of any trust or
power conferred upon the Institutional Trustee under the Declaration, including
the right to direct the Institutional Trustee to exercise the remedies available
to it as the holder of the Debentures. The Indenture provides that the Debt
Trustee (as defined herein) shall give holders of Debentures notice of all
defaults or events of default within 30 days after occurrence. However, except
in the cases of a default or an event of default in payment on the Debentures,
the Debt Trustee will be protected in withholding such notice if its officers or
directors in good faith determine that withholding of such notice is in the
interest of such holders.
 
     If the Institutional Trustee fails to enforce its rights under the
Debentures in respect of an Indenture Event of Default (as defined herein) after
a holder of record of Trust Preferred Securities has made a written request,
such holder of record of Trust Preferred Securities may, to the extent permitted
by applicable law, institute a legal proceeding against the Company to enforce
the Institutional Trustee's rights under the Debentures. In addition, if the
Company fails to pay interest or principal on the Debentures on the date such
interest or principal is otherwise payable, and such Debt Payment Failure (as
defined herein) is continuing, a holder of Trust Preferred Securities may
directly institute a proceeding for enforcement of payment to such holder of the
principal of or interest on the Debentures having a principal amount equal to
the aggregate stated liquidation amount of the Trust Preferred Securities of
such holder (a "Direct Action") after the respective due date specified in the
Debentures. In connection with such a Direct Action, the Company shall have the
right under the Indenture to set off any payment made to such holder by the
Company. The holders of Trust Preferred Securities will not be able to exercise
directly any other remedy available to the holders of the Debentures. See
"Description of the Trust Preferred Securities--Declaration Events of Default."
 
LIMITED RIGHTS OF ACCELERATION
 
     The Institutional Trustee, as holder of the Debentures, may accelerate
payment of the principal and accrued and unpaid interest on the Debentures only
upon the occurrence and continuation of a Declaration Event of Default or
Indenture Event of Default, which generally are limited to payment defaults,
breaches of certain covenants, certain events of bankruptcy, insolvency and
reorganization of the Company and certain events of dissolution of the Trust.
See "Description of the Trust Preferred Securities--Declaration Events of
Default." Accordingly, there is no right to acceleration upon default by the
Company of its payment obligations under the Guarantee.
 
TRADING PRICE OF THE TRUST PREFERRED SECURITIES
 
     The Trust Preferred Securities may trade at a price that does not fully
reflect the value of accrued but unpaid interest with respect to the underlying
Debentures. A holder who disposes of his Trust Preferred Securities between
record dates for payments of distributions thereon will be required to include
accrued but unpaid interest on the Debentures through the date of disposition in
income as ordinary income (i.e., interest or, possibly, OID), and to add such
amount to his adjusted tax basis in his pro rata share of the underlying
Debentures deemed disposed of. To the extent the selling price is less than the
holder's adjusted tax basis, a holder will recognize a loss. See "Certain
Federal Income Consequences--Trust Preferred Securities--Interest Income and
Original Issue Discount" and "--Sales, Exchanges or other Dispositions of Trust
Preferred Securities."

                              RECENT DEVELOPMENTS
 
GREENFIELD ACQUISITION
 
     On October 10, 1997, Kennametal and Acquisition Corp. entered into the
Merger Agreement with Greenfield pursuant to which Acquisition Corp. purchased
at $38 per share on November 17, 1997, approximately 16,179,976 shares (98% of
the outstanding) of Greenfield's common stock. The merger occurred on November
18, 1997, and Greenfield became a wholly-owned subsidiary of Kennametal on that
date. The total purchase price for the acquisition of Greenfield (including
estimated transaction costs and assumed Greenfield debt and convertible
redeemable preferred securities of approximately $320 million) is estimated to
be $1.0 billion. There can be no assurance that the Company will effectively
integrate and manage the acquired business or retain the management and the
numerous distributorship customers of Greenfield. In addition there can be no
assurance that the anticipated benefits of the Greenfield acquisition will be
achieved. If Kennametal does not successfully integrate and manage the
acquisition, there could be a material adverse effect on the Company.
 
NEW BANK CREDIT FACILITY
 
     In connection with the acquisition of Greenfield, the Company, on November
17, 1997, entered into the New Bank Credit Facility with BankBoston, N.A.,
Deutsche Bank AG, New York Branch and/or Cayman Islands Branch, Mellon Bank,
N.A. and PNC Bank, National Association. As of November 18, 1997, the Company
had borrowed $500 million in term loans and approximately $300 million in
revolving credit loans under the New Bank Credit Facility. The proceeds from the
loans were principally used to pay for the shares of common stock of Greenfield
purchased in the Tender Offer and the Merger, to pay transaction costs, to
refinance certain indebtedness of Greenfield and to refinance certain
indebtedness of the Company. Subject to certain conditions, the New Bank Credit
Facility permits revolving credit loans of up to $900 million for working
capital requirements, capital expenditures, and general corporate purposes. The
New Bank Credit Facility initially is secured by all of the stock of certain of
Kennametal's significant domestic subsidiaries, by guarantees of certain of such
subsidiaries and by 65% of the stock of Kennametal's significant foreign
subsidiaries. The New Bank Credit Facility contains various restrictive
covenants and affirmative covenants requiring the maintenance of certain
financial ratios. The term loans under the New Bank Credit Facility are subject
to mandatory amortization commencing on November 30, 1998 and all loans mature
on August 31, 2002. Proceeds from the Offering and the Common Stock Offerings
will be used to prepay term loans under the New Bank Credit Facility. See
"Capitalization," "Use of Proceeds" and "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Liquidity and Capital
Resources--Financial Condition."
 
OTHER ACQUISITIONS
 
     The Company recently acquired Rubig G.m.b.H. of Munich, Germany, a marketer
of carbide precision tools for milling, drilling and other metalcutting
applications, Presto Engineers Cutting Tools Limited of Sheffield, United
Kingdom, a manufacturer of industrial high-speed steel cutting tools, and
Car-Max Tool & Cutter Sales, Inc., which is engaged in the distribution of
metalcutting tools and industrial supplies in the Midwest. The companies had
aggregate annual sales of approximately $46 million in 1996. The Company has
recently entered into an agreement to acquire GRS Industrial Supply Company,
which is engaged in the distribution of metalcutting tools and industrial
supplies in the Midwest, with annual sales of approximately $20 million in 1996.
 
COMMON STOCK OFFERINGS
 
     Concurrently with the Offering, the Company is offering           shares of
Common Stock to the public pursuant to the Common Stock Offerings. The Offering
is not contingent upon the consummation of the Common Stock Offerings and the
Common Stock Offerings are not contingent upon the consummation of the Offering.
Proceeds from the Common Stock Offerings will be used to prepay term loans under
the New Bank Credit Facility. This Prospectus Supplement does not constitute an
offer to buy or the solicitation of an offer to sell the Common Stock being
offered by the Common Stock Offerings. The Common Stock Offerings will be made
only by means of the Common Stock Offerings prospectuses.

                                USE OF PROCEEDS
 
     The net proceeds to be received by the Company from the sale of the FELINE
PRIDES, after deducting estimated underwriting discounts and expenses of the
Offering payable by the Company, are expected to be approximately $     million
(or approximately $     million if the Underwriters' over-allotment option is
exercised in full). See "Underwriting." The net proceeds from the Common Stock
Offerings (assuming they are completed and the over-allotment options are not
exercised) are estimated to be $     million. The net proceeds from the Offering
and the Common Stock Offerings will be used to prepay term loans under the New
Bank Credit Facility, which indebtedness was incurred by the Company in
connection with the acquisition of Greenfield, and has a weighted average
interest rate of      %.

     The Company has paid cash dividends in every quarter since fiscal 1947. The
Board of Directors intends to continue its present policy of declaring regular
quarterly dividends when justified by the financial condition of the Company.
The amount of future dividends, if any, will depend on general business
conditions encountered by the Company, earnings, financial condition and capital
requirements of the Company, and such other factors as the Board of Directors
may deem relevant. The payment of dividends is subject to compliance with
certain financial covenants in the New Bank Credit Facility (see "Description of
Common Stock--Covenant Restrictions") and will be subject to certain
restrictions in connection with the Offering (see "Description of the
Debentures").

                  PRO FORMA CONSOLIDATED FINANCIAL INFORMATION
 
     The following Pro Forma Condensed Consolidated Statements of Income, the
Pro Forma Condensed Consolidated Balance Sheet and the pro forma data under
"Prospectus Summary--Summary Condensed Consolidated Financial Information" are
based on the historical financial statements of the Company and Greenfield
adjusted to give effect to the acquisition of Greenfield, the Offering and the
Common Stock Offerings. The Pro Forma Condensed Consolidated Statements of
Income for the year ended June 30, 1997, and for the three months ended
September 30, 1997, assume that the acquisition of Greenfield occurred as of the
first day of the Company's 1997 fiscal year (July 1, 1996). Since Greenfield has
a fiscal year-end of December 31, the historical information included in the Pro
Forma Condensed Consolidated Statement of Income for the year ended June 30,
1997 has been derived from Greenfield's operating results for the twelve months
ended June 30, 1997. The Pro Forma Condensed Consolidated Balance Sheet gives
effect to the acquisition of Greenfield, the Offering and the Common Stock
Offerings as if they had occurred on September 30, 1997.
 
     The pro forma financial information reflects the purchase method of
accounting for the acquisition of Greenfield, and accordingly is based on
estimated purchase accounting adjustments that are subject to further revision
depending upon completion of appraisals or other studies of the fair value of
Greenfield's assets and liabilities. Final purchase accounting adjustments will
differ from the pro forma adjustments presented herein and described in the
accompanying notes due to the results of operations of Greenfield from September
30, 1997, to the date of closing (November 18, 1997). See Note 18 to the
Company's consolidated financial statements included herein.
 
     The pro forma financial information reflects certain assumptions described
above and in the Notes to Pro Forma Condensed Consolidated Statements of Income
and Pro Forma Condensed Consolidated Balance Sheet which follow. The pro forma
financial information, including notes thereto, should be read in conjunction
with the consolidated financial statements of the Company and of Greenfield, and
the related notes thereto, and "Management's Discussion and Analysis of
Financial Condition and Results of Operations" included elsewhere in this
Prospectus Supplement. The pro forma financial information is provided for
informational purposes only and does not purport to present what the Company's
results of operations would actually have been if the acquisition of Greenfield
had occurred on the assumed dates, as specified above, or to project the
Company's financial condition or results of operations for any future period.

(b) Reflects the costs related to the restructuring of Greenfield's South
    Deerfield, Massachusetts operations. In November 1997, Greenfield recorded
    an $11.5 million charge for non-recurring expenses primarily related to the
    restructuring of its South Deerfield operations. These costs primarily
    included write-downs of inventory and machinery and equipment to estimated
    net realizable values, severance costs and other miscellaneous expenses
    relative to Greenfield's decision to discontinue the manufacture and sale of
    certain low-margin product lines. The restructuring will result in a
    reduction in personnel, thereby eliminating excessive costs and redundancies
    in future periods. Greenfield also expects to record additional
    non-recurring expenses of approximately $2.0 million in 1998 related to the
    rearrangement of the remaining operations at its South Deerfield,
    Massachusetts facility. These amounts are not included in the restructuring
    charge.

    fees of approximately $13.1 million related to the New Bank Credit Facility.
 
(e) Reflects the contract adjustment payments of approximately $5.1 million
    related to the FELINE PRIDES.
 
(f) Reflects the net proceeds of approximately $431.0 million from: (i)
    approximately $214.0 million from the issuance of 4.5 million shares of
    Common Stock, net of related transaction costs of approximately $11.0
    million; and (ii) approximately $217.0 million from the issuance of $225.0
    million of Company-obligated, mandatorily redeemable securities of

    Company-obligated, mandatorily redeemable securities of subsidiary holding
    solely parent company debentures, net of the estimated portion of the
    anticipated transaction costs related solely to the trust preferred
    securities of approximately $2.7 million.
 
(h) Reflects: (i) the contract adjustment payments of approximately $5.1 million
    related to the FELINE PRIDES; and (ii) the estimated portion of anticipated

                              ACCOUNTING TREATMENT
 
     The financial statements of the Trust will be reflected in Kennametal's
consolidated financial statements with the $          Trust Preferred Securities
shown as Company-obligated mandatorily redeemable securities of a subsidiary
holding solely parent company debentures. The financial statement footnotes of
Kennametal will reflect that the sole asset of Kennametal Financing I will be
approximately $          principal amount of      Debentures due          , 200
of Kennametal. Dividends on the Trust Preferred Securities will be reflected as
a charge to the Company's consolidated income, identified as minority interest
related to preferred securities of subsidiary, whether paid or accrued.
 
     The Purchase Contracts are forward transactions in the Company's common
equity. Upon settlement of a Purchase Contract, the Company will receive the
Stated Amount of such Purchase Contract and will issue the requisite number of
shares of Common Stock. The Stated Amount thus received will be credited to
shareholders' equity allocated between the common stock and paid-in capital
accounts. At the date of issuance, the present value of the Contract Adjustment
Payments, if any, will initially be charged to equity, with an offsetting credit
to liabilities.
 
     Upon the issuance of shares of Common Stock upon settlement of the Purchase
Contracts, it is anticipated that the FELINE PRIDES will be reflected in the
Company's earnings per share calculations using the treasury stock method. Under
this method, the number of shares of Common Stock used in calculating earnings
per share is deemed to be increased by the excess, if any, of the number of
shares issuable upon settlement of the Purchase Contracts over the number of
shares that could be purchased by the Company in the market (at the average
market price during the period) using the proceeds receivable upon settlement.
Consequently, it is anticipated there will be no dilutive effect on the
Company's earnings per share except during periods when the average market price
of Common Stock is above the Threshold Appreciation Price.
 
                                   THE TRUST
 
     The Trust is a statutory business trust formed under Delaware law pursuant
to (i) a declaration of trust, dated as of November   , 1997, executed by the
Company, as depositor (the "Sponsor") and certain of the trustees of the Trust
(the "Kennametal Trustees") and (ii) the filing of a certificate of trust with
the Secretary of State of the State of Delaware on November 12, 1997. Such
declaration will be amended and restated in its entirety substantially in the
form filed as an exhibit to the Registration Statement of which this Prospectus
Supplement forms a part. The Declaration will be qualified as an indenture under
the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"). Upon
issuance of the Trust Preferred Securities, such Trust Preferred Securities
which are initially issued and held as a component of the Income PRIDES will be
pledged with the Collateral Agent to secure the obligations of such Income
PRIDES holders under the related Purchase Contracts. See "Description of the
Purchase Contracts--Pledge Securities and Pledge Agreement" and "Description of
the Trust Preferred Securities--Book-Entry Only Issuance--The Depository Trust
Company." The Company will directly or indirectly acquire Common Securities in
an aggregate liquidation amount equal to 3% of the total capital of the Trust.
The Trust exists for the exclusive purposes of (i) issuing the Trust Securities
representing undivided beneficial interests in the assets of the Trust, (ii)
investing the proceeds of the Trust Securities in the Debentures and (iii)
engaging in only those other activities necessary or incidental thereto unless
otherwise specified in the applicable Prospectus Supplement. The Trust has a
term of approximately seven years, but may dissolve earlier as provided in the
Declaration.
 
     Pursuant to the Declaration, the number of Kennametal Trustees initially is
five. Three of the Kennametal Trustees (the "Regular Trustees") are persons who
are employees or officers of or who are affiliated with the Company. Pursuant to
the Declaration, the fourth trustee will be a financial institution that is
unaffiliated with the Company, which trustee serves as institutional trustee
under the Declaration and as indenture trustee for the purposes of compliance
with the provisions of the Trust Indenture Act (the "Institutional Trustee").
For the purpose of compliance with the provisions of the Trust Indenture Act,
the Institutional Trustee will also act as trustee (the "Guarantee Trustee")
under the Guarantee and as the trustee in the State of Delaware (the "Delaware
Trustee") for the purposes of the Trust Act (as defined herein), until removed
or replaced by the holder of the
 
                                      S-41
<PAGE>   86
 
Common Securities. See "Description of the Guarantee" and "Description of
Preferred Securities--Voting Rights; Amendment of Declaration."
 
     The Institutional Trustee will hold title to the Debentures for the benefit
of the holders of the Trust Securities and the Institutional Trustee will have
the power to exercise all rights, powers and privileges under the Indenture as
the holder of the Debentures. In addition, the Institutional Trustee will
maintain exclusive control of a segregated non-interest bearing bank account
(the "Property Account") to hold all payments made in respect of the Debentures
for the benefit of the holders of the Trust Securities. The Institutional
Trustee will make payments of distributions and payments on liquidation,
redemption and otherwise to the holders of the Trust Securities out of funds
from the Property Account. The Guarantee Trustee will hold the Guarantee for the
benefit of the holders of the Preferred Securities. The Company, as the direct
or indirect holder of all the Common Securities, will have the right to appoint,
remove or replace any Kennametal Trustee and to increase or decrease the number
of Kennametal Trustees; provided, that the number of Kennametal Trustees shall
be at least three, a majority of which shall be Regular Trustees. The Company
will pay all fees and expenses related to the Trust and the offering of the
Trust Securities. See "Description of the Guarantee--Expenses of the Trust."
 
     The rights of the holders of the Preferred Securities, including economic
rights, rights to information and voting rights, are set forth in the
Declaration, the Delaware Business Trust Act, as amended (the "Trust Act"), and
the Trust Indenture Act. See "Description of the Preferred Securities."
 
     The trustee in the State of Delaware is Mark A. Ferrucci, c/o The
Corporation Trust Company, 1209 Orange Street, Wilmington, Delaware 19801. The
principal place of business of the Trust is c/o Kennametal Inc., Route 981
South, at Westmoreland County Airport, Latrobe, PA 15650, and its telephone
number is (412) 539-5000.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
RESULTS OF OPERATIONS
 
THREE MONTHS ENDED SEPTEMBER 30, 1997 COMPARED TO THREE MONTHS ENDED SEPTEMBER
30, 1996
 
     SALES AND MARKETS.  During the quarter ended September 30, 1997,
consolidated sales were $310.8 million, up 13 percent from $275.2 million in the
same quarter last year. Sales rose 16 percent excluding unfavorable foreign
currency translation effects. The increase in sales was primarily attributable
to higher sales of metalworking products in North America and from higher sales
of industrial supplies sold by J&L Industrial Supply ("J&L") and by integrated
industrial supply programs ("Full Service Supply programs"), both operating
within JLK.
 
     Net income for the first quarter ended September 30, 1997, was $17.5
million, or $0.67 per share, as compared with net income of $15.2 million, or
$0.57 per share, in the same quarter last year. The results included expenses of
$5.2 million, or $0.12 per share, for the completion of the relocation and
related expenses incurred in connection with the construction of the new world
headquarters. Earnings benefited from higher sales of metalcutting and related
products in North America and Europe as well as from higher production levels
and productivity improvements related to its focused factory initiative of
rearranging manufacturing layout to improve productivity. This was partially
offset by unfavorable foreign currency translation effects.
 
     During the September 1997 quarter, sales in the North America Metalworking
market increased 7 percent from the previous year. Sales of metalcutting inserts
and toolholding devices in North America increased due to improved economic
conditions in the United States in most major end markets and from continued
emphasis on milling and drilling products. Additionally, sales of metalcutting
and toolholding devices sold through all sales channels in North America,
including sales through the industrial supply market, increased 11 percent.
 
     Sales in the Europe Metalworking market on a local currency basis increased
13 percent over the same quarter a year ago. Including unfavorable foreign
currency translation effects, sales in the Europe Metalworking market were flat.
Demand for metalworking products continued to show improvement during the
quarter in most key end markets as a result of improved market conditions in
Europe, principally in Germany. Sales in the European market have posted
double-digit order gains for four consecutive months.
 
     The Company recently acquired Rubig G.m.b.H. of Munich, Germany, Presto
Engineers Cutting Tools Limited of Sheffield, United Kingdom, and Car-Max Tool &
Cutter Sales, Inc. The companies had aggregate annual sales of approximately $46
million in 1996. The acquisitions were accounted for using the purchase method
of accounting. The consolidated financial statements include the operating
results of each business from the date of acquisition. The Company has also
recently entered into an agreement to acquire GRS Industrial Supply Company,
with annual sales of approximately $20 million in 1996.
 
     In the Asia Pacific Metalworking market, sales decreased slightly as
results were affected by weak economic conditions in Korea, Singapore and
Thailand. Excluding unfavorable foreign currency translation effects, sales in
the Asia Pacific Metalworking market increased 3 percent. Additionally,
effective August 1, 1997, the Company acquired 100 percent of Kennako Japan from
its joint venture partner, Kobe Steel.
 
     Sales in the industrial supply market rose 35.0 percent as a result of
increased sales through mail order, Full Service Supply programs and from
acquisitions. Excluding the acquisitions, sales increased approximately 24
percent. Sales increased because of four additional showrooms, from the
integration of new showroom locations from acquired companies, from further
penetration of existing customers, and from an expanded product offering of more
than 10,000 new stock keeping units ("SKUs") in J&L's 1998 master catalog issued
September 1, 1997.
 
     During the September 1997 quarter, sales in the mining and construction
market increased 10 percent from the previous year as a result of increased
domestic demand for highway construction tools. International sales of mining
and highway construction tools also improved as a result of strong market demand
in South Africa and China.

     COSTS AND EXPENSES.  As a percentage of sales, gross profit margin for the
September 1997 quarter was 42.5 percent as compared with 41.7 percent in the
prior year. The gross profit margin increased primarily as a result of
productivity improvements related in part to the focused factory initiative and
from higher production levels. This increase was partially offset by unfavorable
foreign currency translation effects.
 
     Operating expenses as a percentage of sales were 31.7 percent compared to
31.6 percent last year. Operating expenses increased 13 percent primarily
because of relocation and related costs incurred in connection with the
construction of the new world headquarters, which amounted to approximately $5.2
million during the first quarter. The project is now successfully completed.
Operating expenses also increased because of higher costs related to
acquisitions, and from the JLK showroom expansion program, including higher
direct mail costs and increased direct marketing costs in new territories in the
United States and in Europe.
 
     Interest expense for the September 1997 quarter was $1.2 million compared
to $2.6 million in the same quarter of a year ago. Interest expense decreased as
a result of lower debt balances as the Company used the proceeds received from
the initial public offering ("IPO") of approximately 4.9 million shares of
common stock of JLK.
 
     The effective tax rate for the September 1997 quarter was 39.0 percent
compared to an effective tax rate of 38.9 percent in the prior year.
 
FISCAL YEAR 1997 COMPARED TO FISCAL YEAR 1996
 
     OVERVIEW.  Net income for 1997 was $72.0 million, compared to $69.7 million
last year. While revenues and earnings rose to record highs, earnings were
affected by weakness in the European market, primarily in Germany, and from
negative effects of foreign currency translations due to the strength of the
U.S. dollar. Earnings for 1997 also were affected by additional costs related to
the J&L showroom expansion program, integration of new client-server information
systems and relocation and related costs associated with the construction of a
new world headquarters in Latrobe, Pennsylvania. Earnings in 1997 benefited from
slightly higher sales of metalworking products in North America and from higher
sales of metalworking products and industrial supplies sold to the Industrial
Supply market through mail order and Full Service Supply programs.

     SALES AND MARKETS.  Sales for the year ended June 30, 1997, were $1.2
billion, up 7 percent from $1.1 billion last year. Sales primarily increased in
1997 because of higher sales of metalworking products and industrial
 
                                      S-45
<PAGE>   90
 
supplies sold to the Industrial Supply market by J&L and by Full Service Supply
programs. The increase in sales was offset in part by lower sales of
metalworking products in Europe due to weak economic conditions, especially the
German market, and from negative foreign currency translation effects.
 
     Sales in the North America Metalworking market increased 3 percent over
1996, despite the transfer of small customer accounts to J&L, as a result of
improved economic conditions in the United States and from the continued
emphasis on milling and drilling products. Sales in Canada rose 15 percent
because of increased sales of metalworking products to aerospace and automotive
companies. Additionally, sales of traditional metalworking products sold through
all sales channels in North America, including sales through the Industrial
Supply market, increased 7 percent.
 
     Sales in the Europe Metalworking market decreased 7 percent. Demand for
metalworking products continued to be slow due to weak economic conditions in
Europe, primarily in the German market. Demand in Europe was weak for most of
1997 but began to show improvement during the fourth quarter of fiscal 1997.
Despite the economic situation in Europe, sales continued to post gains in the
United Kingdom and France. In the Asia Pacific Metalworking market, sales rose
16 percent as a result of increased demand in China, Japan and Taiwan, although
sales were affected by soft economic conditions in Korea and Thailand. Excluding
foreign currency translation effects, sales in the Europe Metalworking market
decreased 2 percent, while sales in the Asia Pacific Metalworking market
increased 21 percent.
 
     The Industrial Supply market was the major contributor to the overall sales
increase because of the continued growth of mail order and Full Service Supply
programs. Sales rose 28 percent primarily because of the expanded product
offering of over 20,000 new SKUs in the J&L 1997 master catalog, from the
addition of five new showrooms and from innovative marketing programs. Full
Service Supply programs increased, to a lesser extent, from the continued
ramp-up of existing Full Service Supply programs. Also contributing to the sales
increase was the acquisition of two industrial supply companies during the
fourth quarter of 1997. The acquired companies had annual sales of $36 million
in their latest fiscal year and will provide four additional showroom locations
in the Midwest. Excluding these acquisitions, the Industrial Supply market sales
increased 26 percent. At June 30, 1997, the Company operated a total of 28
showrooms, including six distribution centers in the United States and one in
the United Kingdom, and provided Full Service Supply programs to around 60
customers covering about 120 different facilities.
 
     Sales in the Mining and Construction market increased 6 percent from 1996
as a result of increased domestic and international demand for mining tools.
Highway construction tool sales were flat in the United States, while
international sales declined slightly as a result of weak economic conditions in
Europe.
 
     COSTS AND EXPENSES.  As a percentage of sales, gross profit margin for the
year ended June 30, 1997, was 42.2 percent, compared to 42.1 percent last year.
The gross profit margin improved slightly as a result of the positive effects of
productivity improvements related to the focused factory initiative. These
benefits were partially offset by a less favorable sales mix coupled with
unfavorable foreign currency translation effects.
 
     Operating expenses as a percentage of sales were 31 percent, compared to
30.4 percent last year, excluding the effects of the one-time restructuring
charge in fiscal 1996. Operating expenses increased primarily because of higher
costs related to the J&L showroom expansion program, including higher direct
mail costs and increased direct marketing in new territories in the United
States and in Europe. Operating expenses also increased from higher costs to
support new and existing Full Service Supply programs, from the integration of
new client-server information systems, from higher research and development
costs and from relocation and related costs of $4.7 million associated with the
construction of a new world headquarters.
 
     Interest expense decreased 8 percent because of lower average borrowings
coupled with slightly lower interest rates. The effective tax rate was 38.4
percent in 1997, compared to 38.6 percent in 1996. The decrease in the effective
tax rate resulted from additional tax benefits derived from international
operations.
 
FISCAL YEAR 1996 COMPARED TO FISCAL YEAR 1995
 
     OVERVIEW.  Net income for 1996 was $69.7 million, up 2 percent from $68.3
million in 1995. The 1996 results included a restructuring charge totaling $2.7
million ($0.06 per share) for the relocation of the North
 
                                      S-46
<PAGE>   91
 
America Metalworking Headquarters and for the closure of a manufacturing
facility in Canada. Excluding the restructuring charge, net income for 1996 was
up 5 percent.
 
     Earnings for 1996 increased because of the rapid growth in industrial
supply sales, primarily through mail order and Full Service Supply programs and
from slightly higher sales of metalcutting products in each of the three
metalworking markets. Earnings were affected by a less favorable sales mix and
lower production levels. Further, costs associated with the implementation of
new client-server information systems and focused factory programs reduced
pretax earnings by $10.4 million during 1996.
 
     SALES AND MARKETS.  Sales for the year ended June 30, 1996, were $1.1
billion, up 10 percent from $984 million in 1995. Sales increased in each of the
five markets over 1995. Sales increased in 1996 because of slightly higher sales
volumes and modest price increases.
 
     Sales in the North America Metalworking market were flat compared to the
prior year. Sales of metalcutting inserts and toolholding devices in the United
States were flat, as sales growth was affected by weak economic conditions.
Sales of metalworking products in Canada increased 11 percent because of
increased demand.
 
     In the Europe Metalworking market, sales increased 7 percent because of
higher sales volumes. Demand for metalworking products was slow in Germany,
while sales grew at a faster pace in the United Kingdom and France. Demand in
Europe was stronger in the first half of the fiscal year but slowed as the year
progressed. In the Asia Pacific Metalworking market, sales rose 11 percent as a
result of increased demand. Sales also increased because, effective July 1,
1995, Kennametal began to consolidate its majority-owned subsidiaries in China
and Japan. Excluding foreign currency translation effects, sales in the Europe
and Asia Pacific Metalworking markets increased 6 and 7 percent, respectively.
 
     The Industrial Supply market accounted for the largest percentage sales
gain because of the rapid growth of mail order and Full Service Supply programs.
Sales rose 28 percent as a result of aggressive marketing programs, the
successful geographic showroom expansion program at J&L and new and existing
Full Service Supply programs with large customers. During fiscal 1996, J&L
opened seven showroom locations and at the end of fiscal 1996 operated a total
of 18 showrooms in the United States and one location in the United Kingdom.
Full Service Supply added 18 new contracts, bringing the total number to
slightly more than 50 contracts covering more than 100 plant locations in 1996.
Also, during June 1996, the Company began transferring small customer accounts
from the North America Metalworking market to J&L to provide added customer
service and to further leverage J&L's full complement of metalcutting supplies.
 
     Sales in the Mining and Construction market increased 9 percent over 1995
as a result of strong domestic demand for both mining and highway construction
tools. International sales rose only slightly because of increased competition.
 
     COSTS AND EXPENSES.  As a percentage of sales, gross profit margin for the
year ended June 30, 1996, was 42.1 percent, compared to 43.0 percent in 1995.
The gross profit margin benefited from higher sales volumes and modest price
increases. These benefits were offset by a less favorable sales mix, slightly
higher raw material costs, costs associated with the implementation of focused
factory programs and reduced manufacturing efficiencies because of lower
production levels.
 
     Operating expenses as a percentage of sales were 30.4 percent, compared to
29.9 percent in 1995. Operating expenses increased 12 percent primarily because
of costs related to the implementation of new client-server information systems,
costs necessary to support the higher sales levels, and marketing and showroom
expansion programs at J&L. Results of operations also included a restructuring
charge related to the consolidation of the North America Metalworking
headquarters from Raleigh, North Carolina, to Latrobe, Pennsylvania, and the
closure of a manufacturing facility in Canada. These pretax items were recorded
during the fourth quarter of fiscal 1996 and amounted to $2.7 million.
 
     Interest expense decreased 12 percent because of lower average borrowings
and slightly lower interest rates. The effective tax rate was 38.6 percent in
1996, compared to 39.7 percent in 1995. The decrease in the effective tax rate
resulted from additional tax benefits derived from international operations.

     RESTRUCTURING CHARGE.  During the fourth quarter of fiscal 1996, the
Company recorded a pretax charge of $2.7 million to relocate its North America
Metalworking headquarters from Raleigh, North Carolina, to Latrobe,
Pennsylvania, and to close a manufacturing facility in Canada. The relocation
was made to globalize key functions and to provide a more efficient corporate
structure. As a result, a pretax charge of $2.7 million was recorded to cover
the related one-time costs of employee separation arrangements and early
retirements. In connection with the relocation, the Company is constructing a
new world headquarters building estimated to cost $20 million.
 
     Certain costs resulting from the relocation of employees, hiring and
training new employees, and other costs resulting from the temporary duplication
of certain operations were not included in the one-time charge and will be
included in operating expenses as incurred. The costs related to these items
were estimated to be $9 million pretax and will be incurred during fiscal 1997
and 1998.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     On October 10, 1997, Kennametal and Acquisition Corp. entered into the
Merger Agreement with Greenfield pursuant to which Acquisition Corp. purchased
at $38 per share on November 17, 1997 approximately 16,179,976 shares (98
percent of the outstanding) of Greenfield's common stock. The merger occurred on
November 18, 1997 and Greenfield became a wholly-owned subsidiary of Kennametal
on that date. The total purchase price for the acquisition of Greenfield
(including estimated transaction costs and assumed Greenfield debt and
convertible redeemable preferred securities of approximately $320 million) is
estimated to be $1.0 billion.
 
     In connection with the acquisition of Greenfield, the Company, on November
17, 1997, entered into the New Bank Credit Facility. As of November 18, 1997,
the Company had borrowed $500 million in term loans and approximately $300
million in revolving credit loans under the New Bank Credit Facility. The
proceeds from the loans were principally used to pay for the shares of common
stock of Greenfield purchased in the Tender Offer and the Merger, to pay
transaction costs, to refinance certain indebtedness of Greenfield and to
refinance certain indebtedness of the Company. Subject to certain conditions,
the New Bank Credit Facility permits revolving credit loans of up to $900
million for working capital requirements, capital expenditures, and general
corporate purposes. The New Bank Credit Facility initially will be secured by
all of the stock of certain of Kennametal's significant domestic subsidiaries,
by guarantees of certain of such subsidiaries and by 65 percent of the stock of
Kennametal's significant foreign subsidiaries. The New Bank Credit Facility
contains various restrictive covenants and affirmative covenants requiring the
maintenance of certain financial ratios. The term loans under the New Bank
Credit Facility are subject to mandatory prepayments commencing on November 30,
1998 and all loans mature on August 31, 2002. Proceeds from the Offering and the
Common Stock Offerings will be used to prepay term loans under the New Bank
Credit Facility.
 
     Kennametal's cash flow from operations is the primary source of financing
for capital expenditures and internal growth. The Company and its subsidiaries
generally obtain local financing through credit lines with commercial banks.
 
     During 1997, the Company generated $99.9 million in cash from operations.
Cash provided by operations increased from 1996 primarily because of lower
working capital requirements and slightly higher net income. Capital
expenditures, totaling $73.8 million, were made to construct a new world
headquarters in Latrobe, Pennsylvania, and a manufacturing facility in China,
for new client-server information systems and to upgrade machinery and
equipment. Additionally, the Company paid $17.5 million of cash dividends and
paid $19 million to acquire five small companies throughout 1997. The effects of
the acquisitions were not significant to the Company. During the quarter ended
September 30, 1997, the Company generated $40.6 million in cash from operations.
The increase in cash provided by operations resulted primarily from higher net
income and slightly lower incremental working capital requirements. Net cash
used in investing activities during the quarter ended September 30, 1997 was
$32.4 million. The increase in net cash used in investing activities resulted
from higher capital expenditures and from the acquisition of Rubig G.m.b.H. and
the remaining interest in Kennako Japan from its joint venture partner, Kobe
Steel.

     On January 31, 1997, the Company initiated a stock repurchase program to
repurchase from time to time up to a total of 1.6 million shares of its
outstanding capital stock. During the year ended June 30, 1997, the Company
repurchased approximately 781,000 shares of its Common Stock at a total cost of
approximately $28.7 million. The repurchases were made in the open market or in
negotiated or other permissible transactions. The repurchase of Common Stock was
financed principally by cash from operations and short-term borrowings.
 
     On July 2, 1997, an IPO of approximately 4.9 million shares of common stock
of JLK at a price of $20 per share was consummated. JLK operates the industrial
supply operations consisting of the Company's wholly owned J&L subsidiary and
its Full Service Supply programs. The net proceeds from the offering were
approximately $90 million and represented the sale of approximately 20 percent
of JLK's common stock. The net proceeds were used by JLK to repay $20 million of
indebtedness related to a dividend to the Company and $20 million related to
intercompany obligations to the Company. The Company used these proceeds to
repay short-term debt. In connection with the IPO, the remaining net proceeds
were loaned to the Company, under an intercompany debt/investment and cash
management agreement at a fluctuating rate of interest equal to the Company's
short-term borrowing costs. The Company will maintain unused lines of credit to
enable it to repay any portion of the borrowed funds as the amounts are due on
demand by JLK. The Company owns approximately 80 percent of the outstanding
common stock of JLK and intends to retain a majority of both the economic and
voting interests of JLK.
 
     During 1996, the Company generated $85 million in cash from operations,
which was used primarily to finance $58 million of capital expenditures and to
pay $16 million of cash dividends. Capital expenditures were made to modernize
facilities, to upgrade machinery and equipment, and to acquire new information
systems. In January 1996, the Company announced plans to build a $20 million
facility in Shanghai, China to manufacture cemented carbide metalcutting tools.
Pilot production commenced in the second quarter of fiscal 1998 with full
production beginning in the third quarter of fiscal 1998.
 
     During 1995, the Company generated $57 million in cash from operations,
which was used primarily to finance $43 million of capital expenditures and to
pay $16 million of cash dividends. Capital expenditures were made to modernize
facilities, to upgrade machinery and equipment and to acquire new information
systems.
 
     Capital expenditures for fiscal 1998 (excluding) Greenfield are estimated
to be $70-$80 million of which $16.7 million has been spent through September
30, 1997, and will be used primarily to complete the construction of a new world
headquarters in Latrobe, Pennsylvania and a manufacturing facility in China, to
acquire additional client-server information systems, to construct or acquire a
new Midwest distribution center and to upgrade machinery and equipment.
 
FINANCIAL CONDITION
 
     Kennametal's financial condition continues to remain strong. Total assets
were $869 million in 1997, up 9 percent from $799 million in 1996. Net working
capital was $176 million, down 19 percent from the previous year. The ratio of
current assets to current liabilities was 1.6 in 1997, compared with 2.0 in
1996. Total assets were $920 million at September 30, 1997, up 6 percent from
$869 million at June 30, 1997. Net working capital was $258 million, up 47
percent from $176 million from the previous quarter and the ratio of current
assets to current liabilities was 2.1 as of September 30, 1997 and 1.6 as of
June 30, 1997.
 
     Accounts receivable increased 6 percent to $201 million because of
increased sales and from the effects of acquisitions. Inventories rose slightly
to $210 million due to the growth of sales to the Industrial Supply market, the
effects of acquisitions, offset by the Company's inventory reduction efforts of
manufactured products. Inventory turnover was 3.2 in 1997 and 3.0 in 1996. The
Company will continue to focus on ways to improve inventory turnover and overall
asset utilization.
 
     Total debt (including capital lease obligations) increased 33 percent to
$174 million in 1997. In 1997, total debt increased principally because of the
stock repurchase program and increased capital expenditures. The ratio of total
debt to total capital (i.e., total debt divided by the sum of total debt,
minority interest and shareholders' equity) was 27 percent in 1997 as compared
with 23 percent in 1996. Total debt decreased 42% to $101 million and the
Company's debt-to-capital ratio was 15 percent at September 30, 1997. Total debt
decreased as a result of
 
                                      S-49
<PAGE>   94
 
the application of net proceeds of $90 million received from the IPO of
approximately 4.9 million shares of common stock of JLK.
 
     After the acquisition of Greenfield, the Offering and Common Stock
Offerings and the application of the net proceeds therefrom, total debt will
increase to approximately $668 million and the debt-to-capital ratio will
increase to approximately 40 percent. To maintain financial flexibility and to
optimize the cost of capital, Kennametal's financial objective, over the long
term, is to maintain a total debt-to-capital ratio of not more than 40 percent.
Cash from operations and the Company's debt capacity are expected to continue to
be sufficient to fund capital expenditures, dividend payments, stock
repurchases, acquisitions and operating requirements.
 
ENVIRONMENTAL MATTERS
 
     The Company has been involved in various environmental cleanup and
remediation activities at several of its manufacturing facilities. In addition,
the Company has been named as a potentially responsible party at several
Superfund sites in the United States. However, management believes that, based
on its evaluations and discussions with outside counsel and independent
consultants, that the ultimate resolution of these environmental matters will
not have a material adverse effect on the results of operations, financial
position or cash flows of the Company. See Note 14 to the consolidated financial
statements.
 
NEW ACCOUNTING STANDARDS
 
     The Financial Accounting Standards Board ("FASB") recently issued Statement
of Financial Accounting Standards ("SFAS") No. 128, "Earnings Per Share" and
SFAS No. 129, "Disclosure of Information about Capital Structures." SFAS No. 128
was issued in February 1997 and is effective for periods ending after December
15, 1997. This statement, upon adoption, will require all prior year earnings
per share ("EPS") data to be restated to conform to the provisions of the
statement. This statement's objective is to simplify the computations of EPS and
to make the U.S. standard for EPS computations more compatible with that of the
International Accounting Standards Committee. The Company will adopt SFAS No.
128 in fiscal 1998 and does not anticipate that the statement will have a
significant impact on its reported EPS.
 
     SFAS No. 129 was issued in February 1997 and is effective for periods
ending after December 15, 1997. This statement, upon adoption, will require all
companies to provide specific disclosure regarding their capital structure. SFAS
No. 129 will specify the disclosure for all companies, including descriptions of
their capital structure and the contractual rights of the holders of such
securities. The Company will adopt SFAS No. 129 in fiscal 1998 and does not
anticipate that the statement will have a significant impact on its disclosures.
 
     Additionally, in June 1997, the FASB issued SFAS No. 130, "Reporting
Comprehensive Income" (SFAS No. 130) and SFAS No. 131, "Disclosures About
Segments of an Enterprise and Related Information" (SFAS No. 131). SFAS No. 130
is effective for years ending after December 15, 1997. SFAS No. 130 establishes
standards for reporting and display of comprehensive income and its components
in a full set of general-purpose financial statements. The Company will adopt
SFAS No. 130 in fiscal 1998 and does not anticipate that the statement will have
a significant impact on its disclosures.
 
     SFAS No. 131 introduces a new model for segment reporting called the
"management approach." The management approach is based on the way the chief
operating decision-maker organizes segments within a company for making
operating decisions and assessing performance. SFAS No. 131 is effective for
fiscal years beginning after December 15, 1997. The Company is in the process of
evaluating the effect of applying this statement.
 
EFFECTS OF INFLATION
 
     Despite modest inflation in recent years, rising costs continue to affect
the Company's operations throughout the world. Kennametal strives to minimize
the effects of inflation through cost containment, productivity improvements and
price increases under highly competitive conditions.

                                    BUSINESS
 
     The Company is a vertically integrated global manufacturer, marketer and
distributor of a broad range of consumable tools, supplies and services for the
metalworking, mining and highway construction industries. Kennametal specializes
in developing and manufacturing tools utilizing tungsten carbide powder
metallurgy for the three primary metalcutting methods--turning, milling and
drilling. In addition, through JLK, the Company markets and distributes a broad
line of consumable metalcutting tools, as well as abrasives, machine tool
accessories, hand tools, measuring equipment and other industrial supplies used
in the metalworking industry. The Company is a recognized leader in turning and
milling consumable metalcutting tools and believes it is the largest North
American and the second largest global provider of consumable metalcutting tools
and supplies. Leveraging its expertise in tungsten carbide powder metallurgy,
the Company has developed innovative consumable tools for the mining and
construction industries and believes it is the largest global manufacturer,
marketer and distributor of such tools to these markets.
 
     In November 1997, the Company acquired Greenfield Industries, Inc., the
leading North American manufacturer of drilling and other rotary high-speed
steel consumable metalcutting tools for the metalworking industry. Kennametal
believes that Greenfield's operations strongly complement its core businesses
and that the acquisition of Greenfield, in addition to providing the Company
with opportunities for substantial cost savings, offers significant strategic
benefits, including: (i) providing an important new channel of traditional
industrial distributors through which to sell the Company's products; (ii)
expanding and enhancing the Company's line of drilling products; (iii) allowing
the Company to diversify into new markets such as certain wear products by
leveraging its material science expertise in tungsten carbide powder metallurgy
and (iv) providing the opportunity to introduce and sell each company's products
into the markets served by the other company.
 
     End users of the Company's metalworking products include manufacturers and
suppliers in the aerospace, automotive, construction and farm machinery,
railroad equipment, power generation and transmission equipment, home appliance,
electrical equipment, and oil field services and gas exploration industries. The
Company markets its products through: a technically skilled direct sales force;
JLK's catalogs, showrooms and other direct marketing efforts; JLK's integrated
industrial supply programs; and, with the acquisition of Greenfield, a network
of traditional industrial distributors. This multi-channel product marketing
approach enables the Company to meet the varying needs of metalworking customers
of all sizes which range from same-day ordering and rapid delivery of products
to outsourcing the entire procurement and inventory management process for
metalworking and related products. The Company estimates there are approximately
250,000 metalworking industrial sites in the United States. The Company's
multi-channel distribution network, comprehensive product offering and global
presence allow customers of all sizes the advantage of a single source of supply
for most metalworking needs.
 
     The Company believes five significant trends are currently impacting the
metalworking industry: (i) consolidation of fragmented distribution channels as
customers seek a single source of supply for their metalworking needs; (ii)
increasing demand from large customers to outsource procurement and inventory
management processes through integrated supply programs; (iii) growing demand
for suppliers that can provide a complete selection of tools, supplies and
services globally; (iv) demand for world class capabilities including customer
service, technical application support and information and product technology
while, at the same time, maintaining or reducing costs; and (v) continuing
advances in customers' metalworking manufacturing technology requiring more
technically advanced tools. These factors are resulting in a restructuring and
consolidation in the metalworking industry as tooling manufacturers and
distributors are forced to either become more competitive or seek stronger
partners. The Company's business strategy is designed to capitalize on these and
other trends.
 
     The address of the Company's principal executive offices is Route 981 South
at Westmoreland County Airport, Latrobe, Pennsylvania 15650 and its telephone
number is (412) 539-5000.
 
BUSINESS STRATEGY
 
     The Company's objective is to become the supplier of first choice of
consumable tools, related supplies, and services to the worldwide metalworking
industry and to other industries which can benefit from tungsten carbide
products. The Company believes its market-leadership position results from
successful implementation of its business strategy, the major elements of which
include:
 
                                      S-51
<PAGE>   96
 
     - Expanding Customer Base Through Multi-Channel Distribution.  The Company
      seeks to access potential customers through all primary distribution
      channels. The Company serves its traditional base of large and
      medium-sized metalworking customers through a direct sales force. JLK
      direct markets a broad range of tiered ("good," "better" and "best")
      metalworking consumables and other related products targeted at small and
      medium-sized metalworking customers and offers integrated supply programs
      targeted at large industrial metalworking customers. The acquisition of
      Greenfield, which sells its consumable tools, related products and
      services through a network of more than 2,500 traditional industrial
      distributors, provides Kennametal with access to approximately 50% of the
      North American metalworking market.
 
     - Providing Most Complete Product Offering.  The Company seeks to provide
      the most complete and comprehensive product offering in the metalworking
      industry. As a result of various acquisitions and internal development,
      the Company markets and distributes what it believes is one of the
      broadest lines of tools and services typically used by metalworking
      customers. The recent acquisition of Greenfield and its consumable
      high-speed steel rotary cutting tools and related products provides the
      Company with the capability to manufacture all of the major consumable
      tools needed by customers in their metalcutting manufacturing processes.
 
     - Expanding Strong Global Presence.  Kennametal is committed to growing its
      global presence as demonstrated by its position as the second-largest
      provider of tools to the European metalworking industry, the world's
      largest metalworking market and plans to expand its presence in Asia
      Pacific. The Company recently completed construction of a cutting tool
      manufacturing facility in Shanghai, China for a total investment of about
      $20 million and increased to 100% its ownership interest in a sales and
      marketing subsidiary in Japan. The Company also has targeted marketing
      efforts in Eastern Europe and Russia and other developing countries.
 
     - Providing Superior Customer Service, Product Availability, and Technical
      Support.  The Company's skills in rapidly filling orders, maintaining high
      levels of product availability and providing technical product application
      support are vital to the ability of its metalworking customers to meet
      their production and delivery schedules in a cost-effective manner.
      Kennametal's sophisticated order entry and inventory management systems
      enable the Company to ship more than 90 percent of its products from
      stock. In addition, the Company's technically skilled direct sales force
      of over 700 persons provide on-site product selection and application
      support to enable customers to optimize their metalcutting processes. The
      addition of Greenfield's more than 70 technical specialists broadens the
      Company's technical support capability into high-speed steel drilling
      applications.
 
     - Maintaining Leadership in Product Innovation.  As a result of its
      commitment to research and development, the Company has brought to market
      during the past few years a number of new or improved metalcutting
      products. The exacting requirements of modern high-precision metalcutting,
      along with advances in manufacturing technology, exacting manufacturing
      specifications, and new workpiece materials, are driving the demand for
      new and improved consumable tools and systems capable of achieving
      superior technical performance with high and uniform quality. The Company
      believes that its reputation for supplying high quality and
      technologically innovative consumable metalcutting tools and supplies to
      the metalworking industry has been very significant in achieving its
      market position.
 
     - Leveraging Use of Information Technology.  The Company's decision to
      invest nearly $40 million in a business information system utilizing SAP
      R-3 software demonstrates its commitment to the use of information
      technology. This system, which is expected to be fully operational in
      fiscal 1999, will link sales, distribution, manufacturing, purchasing and
      accounting activities at all major sites throughout Kennametal and is
      designed to enhance customer service, operational effectiveness and
      management decision-making.
 
     In addition to the above business strategies, the Company seeks to continue
to improve operating efficiencies as well as to pursue selected acquisitions
that enhance its distribution channels, complement its existing product
offerings or strengthen its geographic presence.

BUSINESS SEGMENT AND MARKETS
 
     The Company operates predominantly as a tooling supplier specializing in
powder metallurgy, which represents a single business segment. While many of the
Company's products are similar in composition, sales are classified into three
markets: metalworking, industrial supply, and mining and construction.
 
     METALWORKING MARKETS.  Kennametal markets, manufactures and distributes a
full line of products and services for the metalworking industry. The Company
provides metalcutting tools to manufacturing companies in a wide range of
industries throughout the world.
 
     A Kennametal tooling system usually consists of a steel toolholder and an
indexable cutting tool called an insert. During a metalworking operation, the
toolholder is positioned in a machine tool that provides the turning power.
While the workpiece or toolholder is rapidly rotating, the cutting tool insert
contacts the workpiece and cuts or shapes the workpiece. The cutting tool insert
is consumed during use and must be replaced periodically. Metalcutting
operations include turning, boring, threading, grooving, milling and drilling.
The Company also makes wear-resistant parts for use in abrasive environments and
specialty applications.
 
     INDUSTRIAL SUPPLY MARKET.  Kennametal distributes a full line of industrial
supplies to the metalworking industry principally through JLK. These products
include cutting tools, abrasives, precision measuring devices, power tools and
hand tools, machine tool accessories and, to a lesser extent, some maintenance,
repair and operating supplies. The majority of industrial supplies distributed
by the Company are purchased from other manufacturers, although the industrial
supply product offering does include Kennametal-manufactured items.
 
     MINING AND CONSTRUCTION MARKET.  Mining and construction cutting tools are
fabricated from steel parts and tipped with cemented carbide. Mining tools, used
primarily in the coal industry, include longwall shearer and continuous miner
drums, blocks, bits, pinning rods, augers and a wide range of mining tool
accessories. The Company also supplies compacts for mining, quarrying, water
well drilling and oil and gas exploration. Construction cutting tools include
carbide-tipped bits for ditching, trenching and road planing, grader blades for
site preparation and routine roadbed control, and snowplow blades and shoes for
winter road plowing.
 
     The Company also makes proprietary metallurgical powders for use as a basic
material in many of its metalworking, mining and construction products. In
addition, the Company produces a variety of metallurgical powders and related
materials for specialized markets. These products include intermediate carbide
powders, hardfacing materials and matrix powders that are sold to manufacturers
of cemented carbide products, oil and gas drilling equipment and diamond drill
bits.
 
     INTERNATIONAL OPERATIONS.  The Company's principal international operations
are conducted in Western Europe and Canada. In addition, the Company has joint
ventures in India, Italy, Poland and Russia, manufacturing and sales
subsidiaries in Asia Pacific and sales agents and distributors in eastern Europe
and other areas of the world.
 
     The Company's international operations are subject to the usual risks of
doing business in those countries, including currency fluctuations and changes
in social, political and economic environments. In management's opinion, the
Company's business is not materially dependent upon any one international
location involving significant risk.
 
MARKETING AND DISTRIBUTION
 
     The Company's products are sold through three distinct channels: a direct
sales force, Full Service Supply programs, and retail showrooms and mail-order
catalogs. The Company's manufactured products are sold to end users primarily
through a direct sales force. Service engineers and technicians directly assist
customers with product design, selection and application. In addition,
Kennametal-manufactured products, together with a broad range of purchased
products, are sold through Full Service Supply programs and retail showrooms and
mail-order catalogs. The Company also uses independent distributors and sales
agents in the United States and certain international markets.

GREENFIELD
 
     GENERAL.  Greenfield is a leading manufacturer of consumable cutting tools
and related products used primarily in industrial applications and is the
largest North American producer of expendable rotary cutting tools used to cut
metal and other industrial materials. Greenfield's products are sold in six
principal markets: industrial, electronics, energy and construction, engineered
products, consumer and marine. Greenfield offers products made from high-speed
steel and tungsten carbide materials; and each accounts for approximately half
of Greenfield's revenues. In addition, Greenfield manufactures and markets a
line of marine products.
 
     MARKETS AND PRODUCTS.  Greenfield manufactures and markets expendable
cutting tools and carbide products to the industrial, electronics, energy and
construction, engineered products, and consumer markets. Greenfield manufactures
a wide variety of cutting tools. High-speed steel is the predominant material
for rotary cutting tools, offering high performance in a broad range of
applications. Tungsten carbide materials are costlier and more durable and are
preferred in certain applications. Greenfield also manufactures and markets a
line of marine products. Greenfield's brand names enjoy a high degree of
recognition in their respective markets. Greenfield also supplies a number of
industrial and consumer private label customers with its products, including
Sears' line of Craftsman(R) drill bits.
 
     Greenfield is the largest producer in North America of rotary cutting tools
for industrial applications. Products sold in the industrial market include
rotary cutting tools and related products such as drills, reamers, taps, end
mills, burrs, routers, counterbores and countersinks. Greenfield also
manufactures and markets an extensive line of hardware products, primarily
stationary and portable power tool accessories for use in the industrial and
consumer markets. In 1996, the industrial market accounted for approximately 51%
of Greenfield's consolidated net sales.
 
     Greenfield manufactures and markets small diameter circuit board drills for
the electronics market. Greenfield believes that it is one of the largest
worldwide manufacturers of circuit board drills and routers. In 1996, the
electronics market accounted for approximately 12% of Greenfield's consolidated
net sales.
 
     Greenfield believes that it is the largest independent supplier of oilfield
compacts in the world. Compacts are the cutting edges of oil well drilling bits,
which are commonly referred to as "rock bits." Greenfield's compacts are used
both for oil and natural gas drilling. Natural gas reserves tend to be found
deeper than oil, thereby increasing the utilization of rock bits. Greenfield is
a significant producer of tungsten carbide-tipped mining bits for the United
States coal mining industry and manufactures mining bit accessories and
carbide-tipped bits used in highway road resurfacing. In 1996, the energy and
construction market accounted for approximately 12% of Greenfield's consolidated
net sales.
 
     Greenfield is an on-demand producer of custom-made tungsten carbide preform
wear parts for use in the tool and die industry including stamping dies, powder
metal tooling, container and impact tooling, seal rings, extruded rods, wear
parts and steel processing parts. Greenfield also manufactures tungsten carbide
balls used in rotary equipment such as pumps and mixers and seats which are
components in the check valves used in oil producing pumps, tungsten carbide
trim parts used in oil field chokes, mechanical face seals and ceramic-based
wear parts. In 1996, the engineered products market accounted for approximately
13% of Greenfield's consolidated net sales.
 
     Greenfield is an active supplier of consumer drill bits, saws, hand tools
and other products to the do-it-yourself market, which includes Sears, Home
Depot and other major retailers and includes products sold under private label
brands such as the Sears Craftsman(R) drill line, which Greenfield has supplied
for more than 65 years. In 1996, the consumer market accounted for approximately
7% of Greenfield's consolidated net sales.
 
                                      S-54
<PAGE>   99
 
     Greenfield also manufactures a line of marine products. Greenfield's marine
products include submersible pumps, activating switches, magnetic compasses,
DC-powered winches and various electronic instruments and gauges. In 1996, the
marine market accounted for approximately 5% of Greenfield's consolidated net
sales.
 
     MARKETING AND DISTRIBUTION.  Greenfield's cutting tool products are sold
primarily through selected distributors supported by Greenfield's technical
sales personnel. In addition to distributors, Greenfield sells cutting tool
products as well as other products directly to private label, catalog, large
industrial and other customers having special technical or other requirements.
Generally, Greenfield's major brands are represented by distinct sales forces.
Greenfield's sales force numbers approximately 150 and sells to over 2,500
independent distributors in North America and worldwide.
 
COMPETITION
 
     Kennametal is one of the world's leading producers of cemented carbide
tools and maintains a strong competitive position, especially in North America
and Europe. There is active competition in the sale of all products made by the
Company, with approximately 30 companies engaged in the cemented carbide
business in the United States and many more outside the United States. Several
competitors are divisions of larger corporations. In addition, several hundred
fabricators and toolmakers, many of whom operate out of relatively small shops,
produce tools similar to those made by the Company and buy the cemented carbide
components for such tools from cemented carbide producers, including the
Company. Major competition exists from both U.S.-based and international-based
concerns. In addition, the Company competes with thousands of industrial supply
distributors.
 
     The purchase price of consumable cutting tools is relatively small compared
to the customer's significant investment in production equipment, control
systems, work piece materials and a trained work force. However, use of the
customer's equipment and systems can be significantly impaired if consumable
cutting tools are of inconsistent quality, fail to meet technical
specifications, or are not readily available. The Company therefore believes
that its competitive strengths rest on the consistently high quality of its
products, state-of-the-art manufacturing capabilities, customer service,
multiple distribution channels, global presence, and its ability to develop new
and improved systems responsive to its customer's needs. These factors
frequently permit the Company to sell many of its products based on their value
added to the customer, rather than strictly on price.
 
SEASONALITY
 
     Seasonal variations do not have a major effect on the Company's and
Greenfield's business. However, to varying degrees, traditional summer vacation
shutdowns of metalworking customers' plants and holiday shutdowns often affect
the Company's first and second fiscal quarters and Greenfield's third and fourth
fiscal quarters.
 
RESEARCH AND DEVELOPMENT
 
     The Company is involved in research and development of new products and
processes. Research and development expenses totaled, $18.7 million, $20.6
million and $24.1 million in 1995, 1996 and 1997, respectively. Additionally,
certain costs associated with improving manufacturing processes are included in
cost of goods sold. The Company holds a number of patents and licenses which, in
the aggregate, are not material to the operation of the business.
 
     The Company has brought a number of new products to market during the past
few years. These include metalcutting inserts that incorporate innovative tool
geometries or compositions for improved chip control and productivity. These new
compositions include KC994M* multi-coated metalcutting inserts for milling
applications, KC9010* and KC9025* multi-coated metalcutting inserts for turning
applications, Kyon 3500* ceramic metalcutting inserts for machining cast irons,
and KCD25* diamond-coated metalcutting inserts for machining aluminum alloys and
other nonferrous materials.

EMPLOYEES
 
     The Company employed approximately 7,500 persons at June 30, 1997, of which
4,700 were located in the United States and 2,800 in other parts of the world,
principally Europe and Asia Pacific. Approximately 1,100 employees were
represented by labor unions, of which 170 were hourly-rated employees located at
plants in the Latrobe, Pennsylvania area. The remaining 930 employees
represented by labor unions were employed at seven plants located outside of the
United States. The Company has not experienced any work stoppages in the last
five years and considers its labor relations to be generally good.
 
     At December 31, 1996, Greenfield had approximately 5,000 employees
worldwide. Approximately 1,000 employees at eight of Greenfield's facilities are
covered under collective bargaining agreements which expire through June 2002.
Greenfield has not experienced any work stoppages in the last five years and
considers its relations with employees to be good.
 
REGULATION
 
     Compliance with government laws and regulations pertaining to the discharge
of materials or pollutants into the environment or otherwise relating to the
protection of the environment did not have a material effect on the Company's
capital expenditures, earnings or competitive position for fiscal 1997, nor is
such compliance expected to have a material effect in the future.
 
     The Company has been involved in various environmental cleanup and
remediation activities at several of its manufacturing facilities. In addition,
the Company has been named as a potentially responsible party at several
Superfund sites in the United States. However, in management's opinion, based on
its evaluations and discussions with outside counsel and independent
consultants, the ultimate resolution of these environmental matters will not
have a material adverse effect on the results of operations, financial position
or cash flows of the Company.
 
     The Company maintains a Corporate Environmental, Health and Safety ("EH&S")
Department as well as an EH&S Policy Committee to ensure compliance with
environmental regulations and to monitor and oversee remediation activities. In
addition, the Company has established an EH&S administrator at each of its
domestic manufacturing facilities. The Company's financial management team
periodically meets with members of the Corporate EH&S Department and the
Corporate Legal Department to review and evaluate the status of environmental
projects and contingencies. On a quarterly and annual basis, management
establishes or adjusts financial provisions and reserves for environmental
contingencies in accordance with Statement of Financial Accounting Standards No.
5, "Accounting for Contingencies."
 
     Greenfield regularly conducts an environmental assessment consistent with
recognized standards of due diligence on properties and businesses which it
acquires. To date, these assessments have not identified contamination, which
would result in material expenses, in respect of acquired properties that would
be reasonably likely to result in a material adverse effect on Greenfield's
business, results of operations or financial condition. As a general rule,
Greenfield intends to use such assessments as part of the evaluation of proposed
acquisitions. However, there can be no assurance that environmental assessments
have identified, or will in the future identify, all potential liabilities
relating to Greenfield's properties and businesses, that any indemnification
agreements that can be negotiated will cover all potential liabilities, or that
changes in cleanup requirements or subsequent events at Greenfield's properties
or at off-site locations will not result in significant costs to Greenfield.

(a) In January 1996, the Company announced plans to construct a $20-million
    facility in Shanghai, China, to manufacture cemented carbide metalcutting
    tools. Operations began in the second quarter of 1998.
 
     The Company also has a network of warehouses and customer service centers
located throughout North America, Western Europe, Asia and Australia, a
significant portion of which are leased. The majority of the Company's research
and development efforts are conducted in a corporate technology center located
adjacent to world headquarters in Latrobe, Pennsylvania and in Furth, Germany.
 
     All significant properties are used in the Company's dominant business of
powder metallurgy, tools, tooling systems and supplies. The Company's production
capacity is adequate for its present needs. The Company believes that its
properties have been adequately maintained, are generally in good condition and
are suitable for the Company's business as presently conducted.
 
     Greenfield's headquarters are located in Augusta, Georgia. Greenfield owns
significant manufacturing facilities in Arkansas, Georgia, Indiana,
Massachusetts, Michigan, North Carolina, Ohio, Pennsylvania, South Carolina and
Virginia, and leases significant facilities in Illinois, Massachusetts,
Missouri, Vermont and Wisconsin. Greenfield also maintains, through ownership or
leases, smaller manufacturing, office, warehouse and research facilities, as
well as property held for sale, in eight other states and seven other countries.
In the event of a cancellation or termination of a lease relating to any of
Greenfield's leased properties, Greenfield anticipates no difficulty in
connection with leasing alternate space at reasonable rates.
 
LEGAL MATTERS
 
     There are no material legal proceedings pending against the Company.

                        DESCRIPTION OF THE FELINE PRIDES
 
     The following descriptions of certain terms of the FELINE PRIDES offered
hereby supplements, and to the extent inconsistent therewith replaces, the
description of the general terms and provisions of the FELINE PRIDES set forth
in the accompanying Prospectus Supplement, to which reference is hereby made.
The summaries of certain provisions of documents described below are not
necessarily complete, and in each instance reference is hereby made to the
copies of such documents (including the definitions therein of certain terms)
which are on file with the Commission. Wherever particular sections of, or terms
defined in, such documents are referred to herein, such sections or defined
terms are incorporated by reference herein. Capitalized terms not defined herein
have the meanings assigned to such terms in the accompanying Prospectus
Supplement.
 
     Each FELINE PRIDES will be issued under the Purchase Contract Agreement
between the Company and the Purchase Contract Agent. Each FELINE PRIDES offered
hereby initially will consist of a unit (referred to as an Income PRIDES) with a
Stated Amount of $50 comprised of (a) a Purchase Contract under which (i) the
holder (including, initially, an Underwriter) will purchase from the Company on
the Purchase Contract Settlement Date, for an amount of cash equal to the Stated
Amount, a number of newly issued shares of Common Stock equal to the Settlement
Rate described below under "Description of the Purchase Contracts--General," and
(ii) the Company will pay Contract Adjustment Payments, if any, to the holder,
and (b)(i) beneficial ownership of a related   % Trust Preferred Security,
having a stated liquidation amount per Trust Preferred Security equal to the
Stated Amount, representing a preferred, undivided beneficial ownership interest
in the assets of the Trust, which will consist solely of the Debentures, (ii) in
the case of a distribution of the Debentures upon the dissolution of the Trust
as a result of an Investment Company Event, as described below, or otherwise,
Debentures having a principal amount equal to the Stated Amount or (iii) upon
the occurrence of a Tax Event Redemption prior to the Purchase Contract
Settlement Date, the Applicable Ownership Interest in the Treasury Portfolio.
"Applicable Ownership Interest" means, with respect to an Income PRIDES and the
U.S. Treasury Securities in the Treasury Portfolio, (A) a 1/20, or 5%, undivided
beneficial ownership interest in $1,000 principal amount of each such security
which is a principal strip and (B) for each scheduled interest payment date on
the Debentures that occurs after the Tax Event Redemption Date, a   % undivided
beneficial ownership interest in $1,000 face amount of such security which is an
interest strip maturing on such date. The purchase price of each Income PRIDES
will be allocated between the related Purchase Contract and the related Trust
Preferred Security in proportion to their respective fair market values at the
time of purchase. The Company expects that, at the time of issuance, the fair
market value of each Trust Preferred Security will be equal to $       and the
fair market value of each Purchase Contract will be equal to $       . Such
position generally will be binding on each beneficial owner of each Income
PRIDES (but not on the IRS (as defined herein)). See "Certain Federal Income Tax
Consequences--Income PRIDES--Allocation of Purchase Price." As long as a FELINE
PRIDES is in the form of an Income PRIDES, the related Trust Preferred
Securities or Treasury Portfolio, as applicable, will be pledged to the
Collateral Agent, to secure the holder's obligation to purchase Common Stock
under the related Purchase Contracts.
 
SUBSTITUTION OF PLEDGED SECURITIES
 
     Each holder (including, initially, an Underwriter) of an Income PRIDES
(unless a Tax Event Redemption has occurred) will have the right, at any time on
or prior to the fifth Business Day immediately preceding the Purchase Contract
Settlement Date, to substitute for the related Trust Preferred Securities held
by the Collateral Agent Treasury Securities in an aggregate principal amount
equal to the aggregate stated liquidation amount of such Trust Preferred
Securities. Such Treasury Securities will be pledged with the Collateral Agent
to secure the holder's obligation to purchase Common Stock under the related
Purchase Contracts. Because Treasury Securities are issued in integral multiples
of $1,000, holders of Income PRIDES may make such substitution only in integral
multiples of 20 Income PRIDES; provided, however, if a Tax Event Redemption has
occurred prior to the Purchase Contract Settlement Date and the Treasury
Portfolio has become a component of the Income PRIDES, holders of such Income
PRIDES may make such substitutions only in integral multiples of 8,000 Income
PRIDES (but obtaining the release of the Treasury Portfolio rather than the
Trust Preferred Securities), at any time on or prior to the second Business Day
immediately preceding the Purchase Contract Settlement Date. FELINE PRIDES with
respect to which Treasury Securities have been substituted for the related Trust
Preferred Securities or the Treasury Portfolio, as the case may be, as
collateral to secure such holder's obligations under the
 
                                      S-59
<PAGE>   104
 
related Purchase Contracts will be referred to as Growth PRIDES. To create 20
Growth PRIDES (unless a Tax Event Redemption has occurred), the Income PRIDES
holder will (a) deposit with the Collateral Agent a Treasury Security having a
principal amount at maturity of $1,000 and (b) transfer 20 Income PRIDES to the
Purchase Contract Agent accompanied by a notice stating that the Income PRIDES
holder has deposited a Treasury Security with the Collateral Agent and
requesting that the Purchase Contract Agent instruct the Collateral Agent to
release to such holder the 20 Trust Preferred Securities relating to such 20
Income PRIDES. Upon such deposit and receipt of an instruction from the Purchase
Contract Agent, the Collateral Agent will effect the release of the related 20
Trust Preferred Securities from the pledge under the Pledge Agreement free and
clear of the Company's security interest therein to the Purchase Contract Agent,
which will (i) cancel the 20 Income PRIDES, (ii) transfer 20 related Trust
Preferred Securities to such holder and (iii) deliver 20 Growth PRIDES to the
holder. The Treasury Security will be substituted for the Trust Preferred
Securities and will be pledged with the Collateral Agent to secure the holder's
obligation to purchase Common Stock under the related Purchase Contracts. Each
Growth PRIDES will consist of a unit with a Stated Amount of $50 comprised of
(a) a Purchase Contract with respect to which (i) the holder will purchase from
the Company on the Purchase Contract Settlement Date or earlier for an amount of
cash equal to the Stated Amount of such Growth PRIDES, a number of newly issued
shares of Common Stock of the Company equal to the Settlement Rate described
herein, and (ii) the Company will pay the holder Contract Adjustment Payments,
if any, and (b) a 1/20 undivided beneficial ownership interest in a related
Treasury Security having a principal amount at maturity equal to $1,000 and
maturing on the Business Day immediately preceding the Purchase Contract
Settlement Date. The related Trust Preferred Securities released to the holder
thereafter will trade separately from the resulting Growth PRIDES. Contract
Adjustment Payments, if any, will be payable by the Company on the Growth PRIDES
on each Payment Date from the later of December   , 1997 and the last Payment
Date on which Contract Adjustment Payments, if any, were paid. In addition,
original issue discount will accrue on the related Treasury Securities.
Distributions on any Trust Preferred Securities, up to but not including the
Purchase Contract Settlement Date, including after a substitution of collateral
resulting in the creation of Growth PRIDES, will continue to be payable by the
Trust at the rate of   % of the Stated Amount per annum, subject to the
Company's deferral rights described in "--Current Payments."
 
     Holders who elect to substitute Pledged Securities, thereby creating Growth
PRIDES or recreating Income PRIDES (as discussed below), shall be responsible
for any fees or expenses payable in connection with such substitution. See
"Certain Provisions of the Purchase Contract Agreement and the Pledge
Agreement-- Miscellaneous."
 
RECREATING INCOME PRIDES
 
     On or prior to the fifth Business Day immediately preceding the Purchase
Contract Settlement Date a holder of Growth PRIDES may recreate Income PRIDES
(unless a Tax Event Redemption has occurred) by (a) depositing with the
Collateral Agent 20 Trust Preferred Securities and (b) transferring 20 Growth
PRIDES to the Purchase Contract Agent accompanied by a notice stating that the
Growth PRIDES holder has deposited 20 Trust Preferred Securities with the
Collateral Agent and requesting that the Purchase Contract Agent instruct the
Collateral Agent to release to such holder the related Treasury Security. Upon
such deposit and receipt of instructions from the Purchase Contract Agent, the
Collateral Agent will effect the release of the related Treasury Security from
the pledge of the Pledge Agreement free and clear of the Company's security
interest therein to the Purchase Contract Agent, which will (i) cancel the 20
Growth PRIDES (ii) transfer such Treasury Security to such holder and (iii)
deliver 20 Income PRIDES to such holder; provided, however, if a Tax Event
Redemption has occurred prior to the Purchase Contract Settlement Date and the
Treasury Portfolio has become a component of the Income PRIDES, holders of
Growth PRIDES may make such substitutions (but using the Treasury Portfolio
rather than the Trust Preferred Securities) at any time on or prior to the
second Business Day immediately preceding the Purchase Contract Settlement Date
but only in integral multiples of 8,000 Growth PRIDES. The substituted Trust
Preferred Securities or Treasury Portfolio, as the case may be, will be pledged
with the Collateral Agent to secure the holder's obligation to purchase Common
Stock under the related Purchase Contracts.

CURRENT PAYMENTS
 
     Holders of Income PRIDES are entitled to receive aggregate cash
distributions at a rate of   % of the Stated Amount per annum from and after
December   , 1997, payable quarterly in arrears. The quarterly payments on the
Income PRIDES will consist of (i) cumulative cash distributions on the related
Trust Preferred Securities or the Treasury Portfolio, as applicable, payable at
the rate of   % of the Stated Amount per annum and (ii) Contract Adjustment
Payments payable by the Company at the rate of   % of the Stated Amount per
annum, provided that if such rate is 0%, then the Company will not make any
Contract Adjustment Payments, subject (in the case of distributions on the Trust
Preferred Securities and the Contract Adjustment Payments) to the Company's
right of deferral as described herein.
 
     The ability of the Trust to make the quarterly distributions on the Trust
Preferred Securities is solely dependent upon the receipt of corresponding
interest payments from the Company on the Debentures. The Company has the right
at any time, and from time to time, limited to a period not extending beyond the
maturity of the Debentures, to defer the interest payments on the Debentures. As
a consequence of such deferral, quarterly distributions (unless a Tax Event
Redemption has occurred) to holders of Income PRIDES (or any Trust Preferred
Securities outstanding after the Purchase Contract Settlement Date or after a
substitution of collateral resulting in the creation of Growth PRIDES) would be
deferred (but despite such deferral, would continue to accumulate quarterly and
would accrue interest thereon compounded quarterly at the rate of   % per annum
through and including February 15, 2001, and at the Reset Rate thereafter). The
Company also has the right to defer the payment of Contract Adjustment Payments,
if any, on the related Purchase Contracts until the Purchase Contract Settlement
Date; however, deferred Contract Adjustment Payments, if any, will bear
additional Contract Adjustment Payments at the rate of   % per annum (such
deferred installments of Contract Adjustment Payments, if any, together with the
additional Contract Adjustment Payments, if any, shall be referred to as the
"Deferred Contract Adjustment Payments"). See "Description of the Purchase
Contracts--Contract Adjustment Payments" and "Description of the Trust Preferred
Securities--Distributions." If a Tax Event Redemption has occurred and the
Treasury Portfolio has become a component of the Income PRIDES, quarterly
distributions on the Treasury Portfolio, as a portion of the cumulative
quarterly distributions to the holders of Income PRIDES, will not be deferred.
 
     The Company's obligations with respect to the Debentures will be senior and
unsecured and will rank pari passu in right of payment with all other senior
unsecured obligations of the Company. The Company's obligations with respect to
the Contract Adjustment Payments, if any, will be subordinated and junior in
right of payment to the Company's Senior Indebtedness.
 
VOTING AND CERTAIN OTHER RIGHTS
 
     Holders of Trust Preferred Securities, in their capacities as such holders,
will not be entitled to vote to appoint, remove or replace, or to increase or
decrease the number of Regular Trustees and will generally have no voting rights
except in the limited circumstances described under "Description of Trust
Preferred Securities-- Voting Rights." Holders of Purchase Contracts relating to
the Income PRIDES or Growth PRIDES, in their capacities as such holders, will
have no voting or other rights in respect of the Common Stock.
 
LISTING OF THE SECURITIES
 
     Application will be made to list the Income PRIDES on the NYSE under the
symbol "       " subject to official notice of issuance. If the Growth PRIDES
and Trust Preferred Securities are separately traded, the Company will endeavor
to cause such securities to be listed on such exchange on which the Income
PRIDES are listed, including, if applicable, the NYSE.
 
NYSE SYMBOL OF COMMON STOCK
 
     The Common Stock is listed on the NYSE under the symbol "KMT."

                     DESCRIPTION OF THE PURCHASE CONTRACTS
GENERAL
 
     Each Purchase Contract underlying a FELINE PRIDES (unless earlier
terminated, or earlier settled at the holder's option) will obligate the holder
of such Purchase Contract to purchase, and the Company to sell, on the Purchase
Contract Settlement Date, for an amount in cash equal to the Stated Amount of
such FELINE PRIDES, a number of newly issued shares of Common Stock equal to the
Settlement Rate. The number of newly issued shares of Common Stock issuable upon
settlement of each Purchase Contract on the Purchase Contract Settlement Date
(the "Settlement Rate") will be calculated as follows: (a) if the Applicable
Market Value is equal to or greater than $          (the "Threshold Appreciation
Price") the Settlement Rate will be           ; accordingly, if, between the
date of this Prospectus Supplement and the period during which the Applicable
Market Value is measured, the market price for the Common Stock increases to an
amount that is higher than the Threshold Appreciation Price, the aggregate
market value of the shares of Common Stock issued upon settlement of each
Purchase Contract (assuming that such market value is the same as the Applicable
Market Value of such Common Stock) will be higher than the Stated Amount, and if
such market price is the same as the Threshold Appreciation Price, the aggregate
market value of such shares (assuming that such market value is the same as the
Applicable Market Value of such Common Stock) will be equal to the Stated
Amount; (b) if the Applicable Market Value is less than the Threshold
Appreciation Price but greater than the Reference Price, the Settlement Rate
will be equal to the Stated Amount divided by the Applicable Market Value;
accordingly, if the market price for the Common Stock increases between the date
of this Prospectus Supplement and the period during which the Applicable Market
Value is measured but such market price is less than the Threshold Appreciation
Price such market price, the aggregate market value of the shares of Common
Stock issued upon settlement of each Purchase Contract (assuming that such
market value is the same as the Applicable Market Value of such Common Stock)
will be equal to the Stated Amount; and (c) if the Applicable Market Value is
less than or equal to the Reference Price, the Settlement Rate (which will be
equal to the Stated Amount divided by the Reference Price will be        ;
accordingly, if the market price for the Common Stock decreases between the date
of this Prospectus Supplement and the period during which the Applicable Market
Value is measured, the aggregate market value of the shares of Common Stock
issued upon settlement of each Purchase Contract (assuming that such market
value is the same as the Applicable Market Value of such Common Stock) will be
less than the Stated Amount, and if such market price stays the same, the
aggregate market value of such shares (assuming that such market value is the
same as the Applicable Market Value of such Common Stock) will be equal to the
Stated Amount. "Applicable Market Value" means the average of the Closing Prices
(as defined) per share of Common Stock on each of the thirty consecutive Trading
Days (as defined) ending on the third Trading Day immediately preceding the
Purchase Contract Settlement Date. "Closing Price" of the Common Stock on any
date of determination means the closing sale price (or, if no closing price is
reported, the last reported sale price) of the Common Stock on the NYSE on such
date or, if the Common Stock is not listed for trading on the NYSE on any such
date, as reported in the composite transactions for the principal United States
securities exchange on which the Common Stock is so listed, or if the Common
Stock is not so listed on a United States national or registered securities
exchange, as reported by The Nasdaq Stock Market, or, if the Common Stock is not
so reported, the last quoted bid price for the Common Stock in the
over-the-counter market as reported by the National Quotation Bureau or similar
organization, or, if such bid price is not available, the market value of the
Common Stock on such date as determined by a nationally recognized independent
investment banking firm retained for this purpose by the Company. A "Trading
Day" means a day on which the Common Stock (A) is not suspended from trading on
any national or regional securities exchange or association or over-the-counter
market at the close of business and (B) has traded at least once on the national
or regional securities exchange or association or over-the-counter market that
is the primary market for the trading of the Common Stock.
 
     No fractional shares of Common Stock will be issued by the Company pursuant
to the Purchase Contracts. In lieu of fractional shares otherwise issuable
(calculated on an aggregate basis) in respect of Purchase Contracts being
settled by a holder of Income PRIDES or Growth PRIDES, the holder will be
entitled to receive an amount of cash equal to such fraction of a share times
the Applicable Market Value.
 
     On the Business Day immediately preceding the Purchase Contract Settlement
Date, unless a holder of Income PRIDES or Growth PRIDES (i) has settled the
related Purchase Contracts prior to the Purchase Contract Settlement Date
through the early delivery of cash to the Purchase Contract Agent in the manner
described under "--Early Settlement," (ii) has settled the related Purchase
Contracts with separate cash on the Business Day
 
                                      S-62
<PAGE>   107
 
immediately preceding the Purchase Contract Settlement Date pursuant to prior
notice in the manner described under "--Notice to Settle with Cash," (iii) has
had the Trust Preferred Securities related to such holder's Purchase Contracts
remarketed in the manner described herein in connection with, or (iv) an event
described under "--Termination" below has occurred, then (A) in the case of
Income PRIDES (unless a Tax Event Redemption has occurred), the Company will
exercise its rights as a secured party to dispose of the related Trust Preferred
Securities in accordance with the applicable law, (1) from the proceeds of such
disposition an amount equal to the aggregate stated liquidation amount of such
Trust Preferred Securities will be automatically applied to satisfy in full such
Income PRIDES holder's obligation to purchase Common Stock under the related
Purchase Contracts and (2) the remaining portion of the proceeds of such
disposition, if any, will be remitted to the Purchase Contract for payment to
the holder of such Income PRIDES and (B) in the case of Growth PRIDES or Income
PRIDES (in the event that a Tax Event Redemption has occurred), the principal
amount of the related Treasury Securities or the Treasury Portfolio, as
applicable, when paid at maturity, will automatically be applied to satisfy in
full such holder's obligation to purchase Common Stock under the related
Purchase Contracts. Such Common Stock will then be issued and delivered to such
holder or such holder's designee, upon presentation and surrender of the
certificate evidencing such FELINE PRIDES (a "FELINE PRIDES Certificate") and
payment by the holder of any transfer or similar taxes payable in connection
with the issuance of the Common Stock to any person other than such holder. In
the event that a holder of either Income PRIDES or Growth PRIDES effects the
early settlement of the related Purchase Contract through the delivery of cash
or settles (in the case of Income PRIDES holder) the related Purchase Contract
with cash on the Business Day immediately preceding the Purchase Contract
Settlement Date, the related Trust Preferred Securities, the Treasury Portfolio
or Treasury Securities, as the case may be, will be released to the holder as
described herein. The funds received by the Collateral Agent on the Business Day
immediately preceding the Purchase Contract Settlement Date, upon cash
settlement of a Purchase Contract, will be promptly invested in overnight
permitted investments and paid to the Company on the Purchase Contract
Settlement Date. Any funds received by the Collateral Agent in respect of the
interest earned from the overnight investment in permitted investments will be
distributed to the Purchase Contract Agent for payment to such holders.
 
     Prior to the date on which shares of Common Stock are issued in settlement
of Purchase Contracts, the Common Stock underlying the related Purchase
Contracts will not be deemed to be outstanding for any purpose and the holders
of such Purchase Contracts will not have any voting rights, rights to dividends
or other distributions or other rights or privileges of a shareholder of the
Company by virtue of holding such Purchase Contracts. See "Description of Trust
Preferred Securities--Voting Rights."
 
     Each holder of Income PRIDES or Growth PRIDES, by acceptance thereof, will
under the terms of the Purchase Contract Agreement and the related Purchase
Contracts be deemed to have (a) irrevocably agreed to be bound by the terms of
the related Purchase Contracts and the Pledge Agreement for so long as such
holder remains a holder of such FELINE PRIDES, and (b) duly appointed the
Purchase Contract Agent as such holder's attorney-in-fact to enter into and
perform the related Purchase Contracts on behalf of and in the name of such
holder. In addition, each beneficial owner of Income PRIDES or Growth PRIDES, by
acceptance of such interest, will be deemed to have agreed to treat (i) itself
as the owner of the Trust Preferred Securities constituting a component of an
Income PRIDES, Treasury Portfolio or Treasury Securities, as the case may be,
and (ii) the Debentures as indebtedness of the Company, in each case, for United
States federal, state and local income and franchise tax purposes.
 
REMARKETING
 
     Unless a Tax Event Redemption has occurred pursuant to the Remarketing
Agreement and subject to the terms of the Remarketing Underwriting Agreement to
be dated as of February   , 2001 between the Remarketing Agent, Purchase
Contract Agent and the Collateral Agent, the Trust Preferred Securities of
Income PRIDES holders' who have failed to notify the Purchase Contract Agent, on
or prior to the fifth Business Day immediately preceding the Purchase Contract
Settlement Date (in the manner described under "--Notice to Settle with Cash")
of their intention to settle the related Purchase Contracts with separate cash
on the Business Day immediately preceding the Purchase Contract Settlement Date,
will be remarketed on the third Business Day immediately preceding the Purchase
Contract Settlement Date. The Remarketing Agent will use its reasonable efforts
to remarket such Trust Preferred Securities on such date for settlement on the
Purchase Contract Settlement Date at
 
                                      S-63
<PAGE>   108
 
a price not less than approximately 100.5% of the aggregate stated liquidation
amount of such Trust Preferred Securities, plus accrued and unpaid distributions
(including deferred distributions), if any, thereon. The portion of the proceeds
from such remarketing equal to the aggregate stated liquidation amount of such
Trust Preferred Securities will automatically be applied to satisfy in full such
Income PRIDES holders' obligations to purchase Common Stock under the related
Purchase Contracts. In addition, after deducting as the Remarketing Fee an
amount not exceeding 25 basis points (.25%) from any amount of such proceeds in
excess of the aggregate stated liquidation amount of the remarketed Trust
Preferred Securities, the Remarketing Agent will remit to the Collateral Agent
the remaining portion of such proceeds, if any, for the benefit of such Income
PRIDES holder. Income PRIDES holders whose Trust Preferred Securities are so
remarketed will not otherwise be responsible for the payment of any Remarketing
Fee in connection therewith. If in spite of using its reasonable efforts the
Remarketing Agent cannot remarket the related Trust Preferred Securities of such
holders of Income PRIDES at a price not less than 100% of the aggregate stated
liquidation amount of such Trust Preferred Securities plus accrued and unpaid
distributions, including deferred distributions, if any, resulting in a Failed
Remarketing the Company will exercise its rights as a secured party to dispose
of the Trust Preferred Securities in accordance with applicable law and to
satisfy in full, from the proceeds of such disposition, such Income PRIDES
holder's obligation to purchase Common Stock under the related Purchase
Contract, provided, that with respect to such Trust Preferred Securities, if the
Company exercises such rights as a secured creditor, any accrued and unpaid
distributions (including any deferred distributions) on such Trust Preferred
Securities will be paid in cash by the Company to the holders of record
(immediately prior to such Failed Remarketing) of such Trust Preferred
Securities. The Company will cause a notice of such Failed Remarketing to be
published on the second Business Day immediately preceding the Purchase Contract
Settlement Date by publication in a daily newspaper in the English language of
general circulation in The City of New York, which is expected to be The Wall
Street Journal. In addition, the Company will request, not later than 7 nor more
than 15 calendar days prior to the remarketing date, that the Depositary notify
its participants holding Trust Preferred Securities, Income PRIDES and Growth
PRIDES of such remarketing and of the procedures that must be followed if a
Trust Preferred Security holder wishes to exercise its right to put its Trust
Preferred Security to the Company upon a Failed Remarketing as described herein.
The Company will endeavor to ensure that a registration statement with regard to
the full amount of the Trust Preferred Securities to be remarketed shall be
effective in such form as will enable the Remarketing Agent to rely on it in
connection with the remarketing process. It is currently anticipated that
Merrill Lynch, Pierce, Fenner and Smith Incorporated will be the Remarketing
Agent. See "Description of the FELINE PRIDES--Remarketing" and "Description of
the Debentures--Put Option."
 
EARLY SETTLEMENT
 
     A holder of Income PRIDES (unless a Tax Event Redemption has occurred) may
settle the related Purchase Contracts on or prior to the fifth Business Day
immediately preceding the Purchase Contract Settlement Date by presenting and
surrendering the FELINE PRIDES Certificate evidencing such Income PRIDES at the
offices of the Purchase Contract Agent with the form of "Election to Settle
Early" on the reverse side of such certificate completed and executed as
indicated, accompanied by payment (payable to the Company in immediately
available funds) of an amount equal to the Stated Amount times the number of
Purchase Contracts being settled; provided, however, if a Tax Event Redemption
has occurred prior to the Purchase Contract Settlement Date and the Treasury
Portfolio has become a component of the Income PRIDES, holders of such Income
PRIDES may settle early only in integral multiples of 8,000 Income PRIDES (and
the related Treasury Portfolio) at any time on or prior to the second Business
Day immediately preceding the Purchase Contract Settlement Date. A holder of
Growth PRIDES may settle the related Purchase Contracts or prior to the second
Business Day immediately preceding the Purchase Contract Settlement Date by
presenting and surrendering the FELINE PRIDES Certificate evidencing such Growth
PRIDES at the offices of the Purchase Contract Agent with the form of "Election
to Settle Early" on the reverse side of such certificate completed and executed
as indicated, accompanied by payment (payable to the Company in immediately
available funds) of an amount equal to the Stated Amount times the number of
Purchase Contracts being settled. So long as the FELINE PRIDES are evidenced by
one or more global security certificates deposited with the Depositary (as
defined below), procedures for early settlement will also be governed by
standing arrangements between the Depositary and the Purchase Contract Agent.
HOLDERS MAY SETTLE PURCHASE CONTRACTS EARLY ONLY IN INTEGRAL MULTIPLES OF 20
FELINE PRIDES.
 
                                      S-64
<PAGE>   109
 
     Upon Early Settlement of the Purchase Contracts related to any Income
PRIDES or Growth PRIDES, (a) the holder will receive        newly issued shares
of Common Stock per Income PRIDES or Growth PRIDES having a Stated Amount of $50
(regardless of the market price of the Common Stock on the date of such Early
Settlement), subject to adjustment under the circumstances described in
"--Anti-Dilution Adjustments" below, (b) the Trust Preferred Securities or
Treasury Securities, as the case may be, related to such Income PRIDES or Growth
PRIDES will thereupon be transferred to the holder free and clear of the
Company's security interest therein, (c) the holder's right to receive Deferred
Contract Adjustment Payments, if any, on the Purchase Contracts being settled
will be forfeited, (d) the holder's right to receive future Contract Adjustment
Payments, if any, will terminate and (e) no adjustment will be made to or for
the holder on account of Deferred Contract Adjustment Payments, if any, or any
amounts accrued in respect of Contract Adjustment Payments.
 
     If the Purchase Contract Agent receives a FELINE PRIDES Certificate,
accompanied by the completed "Election to Settle Early" and requisite check or
immediately available funds, from a holder of FELINE PRIDES by 5:00 p.m., New
York City time, on a Business Day, that day will be considered the settlement
date. If the Purchase Contract Agent receives the foregoing after 5:00 p.m., New
York City time, on a Business Day or at any time on a day that is not a Business
Day, the next Business Day will be considered the settlement date.
 
     Upon Early Settlement of Purchase Contracts in the manner described above,
presentation and surrender of the FELINE PRIDES Certificate evidencing the
related Income PRIDES or Growth PRIDES and payment of any transfer or similar
taxes payable by the holder in connection with the issuance of the related
Common Stock to any person other than the holder of such Income PRIDES or Growth
PRIDES, the Company will cause the shares of Common Stock being purchased to be
issued, and the related Trust Preferred Securities, Treasury Portfolios or
Treasury Securities, as the case may be, securing such Purchase Contracts to be
released from the pledge under the Pledge Agreement (described in "--Pledged
Securities and Pledge Agreement") and transferred, within three Business Days
following the settlement date, to the purchasing holder or such holder's
designee.
 
NOTICE TO SETTLE WITH CASH
 
     A holder of an Income PRIDES (unless a Tax Event Redemption has occurred)
or Growth PRIDES wishing to settle the related Purchase Contract with separate
cash on the Business Day immediately preceding the Purchase Contract Settlement
Date must notify the Purchase Contract Agent by presenting and surrendering the
FELINE PRIDES Certificate evidencing such Income PRIDES or Growth PRIDES at the
offices of the Purchase Contract Agent with the form of "Notice to Settle by
Separate Cash" on the reverse side of the certificate completed and executed as
indicated on or prior to 5:00 p.m., New York City time, on the second Business
Day immediately preceding the Purchase Contract Settlement Date in the case of a
Growth PRIDES holder and on the fifth Business Day immediately preceding the
Purchase Contract Settlement Date in the case of an Income PRIDES holder. If a
holder that has given notice of such holder's intention to settle the related
Purchase Contract with separate cash, fails to deliver such cash on the Business
Day immediately preceding the Purchase Contract Settlement Date, then the
Company will exercise its rights as a secured party to dispose of, in accordance
with the applicable law, the related Trust Preferred Securities, Treasury
Portfolios or Treasury Securities, as the case may be to satisfy in full from
such disposition, such holder's obligation to Purchase Common Stock under the
related Purchase Contract.
 
CONTRACT ADJUSTMENT PAYMENTS
 
     Contract Adjustment Payments, will be fixed at a rate per annum of     % of
the Stated Amount per Purchase Contract; provided that if such rate is 0%, then
the Company will not make any Contract Adjustment Payments. Contract Adjustment
Payments that are not paid when due (after giving effect to any permitted
deferral thereof) will bear interest thereon at the rate per annum of     %
thereof, compounded quarterly, until paid. Contract Adjustment Payments, if any,
payable for any period will be computed on the basis of a 360-day year of twelve
30 day-months. Contract Adjustment Payments, if any, will accrue from
          , 1997 and will be payable quarterly in arrears on February 16, May
16, August 16 and November 16 each year, commencing February 16, 1998. Contract
Adjustment Payments will be specified as a positive component of the
distributions on the FELINE PRIDES only if and to the extent that the rate of
distributions on the Trust Preferred Securities, as determined on the date on
which the FELINE PRIDES are priced for sale, is less than the aggregate
distribution rate required on such date for the offer and sale of such FELINE
PRIDES at the price to the public specified on
 
                                      S-65
<PAGE>   110
 
the cover page of this Prospectus Supplement. Accordingly, the final Prospectus
Supplement will indicate whether and to what extent Contract Adjustment Payments
will be required to be made by the Company.
 
     Contract Adjustment Payments, if any, will be payable to the holders of
Purchase Contracts as they appear on the books and records of the Purchase
Contract Agent on the relevant record dates, which, as long as the Income PRIDES
or Growth PRIDES remain in book-entry only form, will be one Business Day prior
to the relevant payment dates. Such distributions will be paid through the
Purchase Contract Agent who will hold amounts received in respect of the
Contract Adjustment Payments, if any, for the benefit of the holders of the
Purchase Contracts relating to such Income PRIDES or Growth PRIDES. Subject to
any applicable laws and regulations, each such payment will be made as described
under "Book-Entry System" below. In the event that the Income PRIDES or Growth
PRIDES do not continue to remain in book-entry only form, the Company shall have
the right to select relevant record dates, which shall be more than one Business
Day but less than 60 Business Days prior to the relevant payment dates. In the
event that any date on which Contract Adjustment Payments, if any, are to be
made on the Purchase Contracts related to the Income PRIDES or Growth PRIDES is
not a Business Day, then payment of the Contract Adjustment Payments payable on
such date will be made on the next succeeding day which is a Business Day (and
without any interest or other payment in respect of any such delay), except
that, if such Business Day is in the next succeeding calendar year, such payment
shall be made on the immediately preceding Business Day, in each case with the
same force and effect as if made on such payment date. A "Business Day" shall
mean any day other than Saturday, Sunday or any other day on which banking
institutions in New York City (in the State of New York) are permitted or
required by any applicable law to close.
 
     The Company's obligations with respect to Contract Adjustment Payments, if
any, will be subordinated and junior in right of payment to the Company's
obligations under the Senior Indebtedness.
 
OPTION TO DEFER CONTRACT ADJUSTMENT PAYMENTS
 
     The Company may, at its option and upon prior written notice to the holders
of the FELINE PRIDES and the Purchase Contract Agent, defer the payment of
Contract Adjustment Payments, if any, on the Purchase Contracts until no later
than the Purchase Contract Settlement Date. However, Deferred Contract
Adjustment Payments, if any, will bear additional Contract Adjustment Payments
at the rate of     % per annum (compounding on each succeeding Payment Date)
until paid. If the Purchase Contracts are terminated (upon the occurrence of
certain events of bankruptcy, insolvency or reorganization with respect to the
Company), the right to receive Contract Adjustment Payments (other than any
accrued but unpaid Contract Adjustment Payments that have not been deferred), if
any, and Deferred Contract Adjustment Payments, if any, will also terminate.
 
     In the event that the Company elects to defer the payment of Contract
Adjustment Payments, if any, on the Purchase Contracts until the Purchase
Contract Settlement Date, each holder of FELINE PRIDES will receive on the
Purchase Contract Settlement Date in respect of the Deferred Contract Adjustment
Payments, in lieu of a cash payment, a number of shares of Common Stock equal to
(x) the aggregate amount of Deferred Contract Adjustment Payments payable to
such holder divided by (y) the Applicable Market Value.
 
     In the event the Company exercises its option to defer the payment of
Contract Adjustment Payments, if any, then, until the Deferred Contract
Adjustment Payments have been paid, the Company shall not declare or pay
dividends on, make distributions with respect to, or redeem, purchase or
acquire, or make a liquidation payment with respect to, any of its capital stock
or make guarantee payments with respect to the foregoing (other than (i)
purchases or acquisitions of capital stock of the Company in connection with the
satisfaction by the Company of its obligations under any employee benefit plans
or the satisfaction by the Company of its obligations pursuant to any contract
or security outstanding on the date of such event requiring the Company to
purchase capital stock of the Company, (ii) as a result of a reclassification of
the Company's capital stock or the exchange or conversion of one class or series
of the Company's capital stock for another class or series of the Company
capital stock, (iii) the purchase of fractional interests in shares of the
Company's capital stock pursuant to the conversion or exchange provisions of the
Company capital stock or the security being converted or exchanged, (iv)
dividends or distributions in capital stock of the Company or (v) redemptions or
purchases of any rights pursuant to the Rights Agreement, or any successor to
such Rights Agreement, and the declaration thereunder of a dividend of rights in
the future).

ANTI-DILUTION ADJUSTMENTS
 
     The formula for determining the Settlement Rate will be subject to
adjustment (without duplication) upon the occurrence of certain events,
including: (a) the payment of dividends (and other distributions) of Common
Stock on Common Stock; (b) the issuance to all holders of Common Stock of
rights, warrants or options entitling them, for a period of up to 45 days, to
subscribe for or purchase Common Stock at less than the Current Market Price (as
defined) thereof; (c) subdivisions, splits and combinations of Common Stock; (d)
distributions to all holders of Common Stock of evidences of indebtedness of the
Company, shares of capital stock, securities, cash or property (excluding any
dividend or distribution covered by clause (a) or (b) above and any dividend or
distribution paid exclusively in cash); (e) distributions consisting exclusively
of cash to all holders of Common Stock in an aggregate amount that, together
with (i) other all-cash distributions made within the preceding 12 months and
(ii) any cash and the fair market value, as of the expiration of the tender or
exchange offer referred to below, of consideration payable in respect of any
tender or exchange offer by the Company or a subsidiary thereof for the Common
Stock concluded within the preceding 12 months, exceeds 15% of the Company's
aggregate market capitalization (such aggregate market capitalization being the
product of the Current Market Price of the Common Stock multiplied by the number
of shares of Common Stock then outstanding) on the date of such distribution;
and (f) the successful completion of a tender or exchange offer made by the
Company or any subsidiary thereof for the Common Stock which involves an
aggregate consideration that, together with (i) any cash and the fair market
value of other consideration payable in respect of any tender or exchange offer
by the Company or a subsidiary thereof for the Common Stock concluded within the
preceding 12 months and (ii) the aggregate amount of any all-cash distributions
to all holders of the Company's Common Stock made within the preceding 12
months, exceeds 15% of the Company's aggregate market capitalization on the
expiration of such tender or exchange offer. The "Current Market Price" per
share of Common Stock on any day means the average of the daily Closing Prices
for the 5 consecutive Trading Days selected by the Company commencing not more
than 30 Trading Days before, and ending not later than, the earlier of the day
in question and the day before the "ex date" with respect to the issuance or
distribution requiring such computation. For purposes of this paragraph, the
term "ex date," when used with respect to any issuance or distribution, shall
mean the first date on which the Common Stock trades regular way on such
exchange or in such market without the right to receive such issuance or
distribution.
 
     In the case of certain reclassifications, consolidations, mergers, sales or
transfers of assets or other transactions pursuant to which the Common Stock is
converted into the right to receive other securities, cash or property, each
Purchase Contract then outstanding would, without the consent of the holders of
the related Income PRIDES or Growth PRIDES, as the case may be, become a
contract to purchase only the kind and amount of securities, cash and other
property receivable upon consummation of the transaction by a holder of the
number of shares of Common Stock which would have been received by the holder of
the related Income PRIDES or Growth PRIDES immediately prior to the date of
consummation of such transaction if such holder had then settled such Purchase
Contract.
 
     If at any time the Company makes a distribution of property to its
stockholders which would be taxable to such stockholders as a dividend for
United States federal income tax purposes (i.e., distributions of evidences of
indebtedness or assets of the Company, but generally not stock dividends or
rights to subscribe to capital stock) and, pursuant to the Settlement Rate
adjustment provisions of the Purchase Contract Agreement, the Settlement Rate is
increased, such increase may give rise to a taxable dividend to holders of
FELINE PRIDES. See "Certain Federal Income Tax Consequences--Purchase Contracts
Adjustment."
 
     In addition, the Company may make such increases in the Settlement Rate as
the Board of Directors of the Company deems advisable to avoid or diminish any
income tax to holders of its capital stock resulting from any dividend or
distribution of capital stock (or rights to acquire capital stock) or from any
event treated as such for income tax purposes or for any other reasons.
 
     Adjustments to the Settlement Rate will be calculated to the nearest
1/10000th of a share. No adjustment in the Settlement Rate shall be required
unless such adjustment would require an increase or decrease of at least one
percent in the Settlement Rate; provided, however, that any adjustments which by
reason of the foregoing are not required to be made shall be carried forward and
taken into account in any subsequent adjustment.
 
                                      S-67
<PAGE>   112
 
     The Company will be required, within ten Business Days following the
adjustment of the Settlement Rate, to provide written notice to the Purchase
Contract Agent of the occurrence of such event and a statement in reasonable
detail setting forth the method by which the adjustment to the Settlement Rate
was determined and setting forth the revised Settlement Rate.
 
     Each adjustment to the Settlement Rate will result in a corresponding
adjustment to the number of shares of Common Stock issuable upon early
settlement of a Purchase Contract.
 
TERMINATION
 
     The Purchase Contracts, and the rights and obligations of the Company and
of the holders of the FELINE PRIDES thereunder (including the right thereunder
to receive accrued Contract Adjustment Payments or Deferred Contract Adjustment
Payments and the right and obligation to purchase Common Stock), will
automatically terminate upon the occurrence of certain events of bankruptcy,
insolvency or reorganization with respect to the Company. Upon such termination,
the Collateral Agent will release the related Trust Preferred Securities, the
Treasury Portfolio or Treasury Securities, as the case may be, held by it to the
Purchase Contract Agent for distribution to the holders, subject in the case of
the Treasury Portfolio to the Purchase Contract Agent's disposition of the
subject securities for cash and the payment of such cash to the holders to the
extent that the holders would otherwise have been entitled to receive less than
$1,000 of any such security. Upon such termination, however, such release and
termination may be subject to a limited delay. In the event that the Company
becomes the subject of a case under the Bankruptcy Code, such delay may occur as
a result of the automatic stay under the Bankruptcy Code and continue until such
automatic stay has been lifted.
 
PLEDGED SECURITIES AND PLEDGE AGREEMENT
 
     The Trust Preferred Securities related to the Income PRIDES or the Treasury
Securities related to the Growth PRIDES or the Treasury Portfolio if a Tax Event
Redemption has occurred prior to the Purchase Contract Settlement Date
(collectively, the "Pledged Securities") will be pledged to the Collateral
Agent, for the benefit of the Company, pursuant to a pledge agreement, to be
dated as of           , 1997 (the "Pledge Agreement"), to secure the obligations
of holders of FELINE PRIDES to purchase Common Stock under the related Purchase
Contracts. The rights of holders of FELINE PRIDES to the related Pledged
Securities will be subject to the Company's security interest therein created by
the Pledge Agreement. No holder of Income PRIDES or Growth PRIDES will be
permitted to withdraw the Pledged Securities related to such Income PRIDES or
Growth PRIDES from the pledge arrangement except (i) to substitute Treasury
Securities for the related Trust Preferred Securities or Treasury Portfolio, as
the case may be, (ii) to substitute Trust Preferred Securities or Treasury
Portfolio, as the case may be for the related Treasury Securities (for both (i)
and (ii), as provided for under "Description of the FELINE PRIDES--Substitution
of Pledged Securities"), (iii) upon the termination or Early Settlement of the
related Purchase Contracts, or (iv) upon the occurrence of a Tax Event
Redemption as provided for under "Description of the Trust Preferred
Securities--Tax Event Redemption." Subject to such security interest and the
terms of the Purchase Contract Agreement and the Pledge Agreement, each holder
of Income PRIDES (unless a Tax Event Redemption has occurred) will be entitled
through the Purchase Contract Agent and the Collateral Agent to all of the
proportional rights and preferences of the related Trust Preferred Securities
(including distribution, voting, redemption, repayment and liquidation rights)
and each holder of Growth PRIDES or Income PRIDES, (if a Tax Event Redemption
has occurred and the Treasury Portfolio has become a component of the Income
PRIDES) will retain beneficial ownership of the related Treasury Securities or
Treasury Portfolio, as applicable, pledged in respect of the related Purchase
Contracts. The Company will have no interest in the Pledged Securities other
than its security interest.
 
     Except as described in "Description of the Purchase Contracts--General,"
the Collateral Agent will, upon receipt of distributions on the Pledged
Securities, distribute such payments to the Purchase Contract Agent, which will
in turn distribute those payments, together with Contract Adjustment Payments,
if any, received from the Company, to the persons in whose names the related
Income PRIDES or Growth PRIDES are registered at the close of business on the
Record Date immediately preceding the date of such distribution.

<PAGE>   113
 
BOOK ENTRY-SYSTEM
 
     The Depository Trust Company (the "Depositary") will act as securities
depositary for the FELINE PRIDES. The FELINE PRIDES will be issued only as
fully-registered securities registered in the name of Cede & Co. (the
Depositary's nominee). One or more fully-registered global security certificates
("Global Security Certificates"), representing the total aggregate number of
FELINE PRIDES, will be issued and will be deposited with the Depositary and will
bear a legend regarding the restrictions on exchanges and registration of
transfer thereof referred to below.
 
     The laws of some jurisdictions require that certain purchasers of
securities take physical delivery of securities in definitive form. Such laws
may impair the ability to transfer beneficial interests in the FELINE PRIDES so
long as such FELINE PRIDES are represented by Global Security Certificates.
 
     The Depositary is a limited-purpose trust company organized under the New
York Banking Law, a "banking organization" within the meaning of the New York
Banking Law, a member of the Federal Reserve System, a "clearing corporation"
within the meaning of the New York Uniform Commercial Code and a "clearing
agency" registered pursuant to the provisions of Section 17A of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"). The Depositary holds
securities that its participants ("Participants") deposit with the Depositary.
The Depositary also facilitates the settlement among Participants of securities
transactions, such as transfers and pledges, in deposited securities through
electronic computerized book-entry changes in Participants' accounts, thereby
eliminating the need for physical movement of securities certificates. Direct
Participants include securities brokers and dealers, banks, trust companies,
clearing corporations and certain other organizations ("Direct Participants").
The Depositary is owned by a number of its Direct Participants and by the NYSE,
the American Stock Exchange, Inc., and the National Association of Securities
Dealers, Inc. Access to the Depositary system is also available to others, such
as securities brokers and dealers, banks and trust companies that clear
transactions through or maintain a direct or indirect custodial relationship
with a Direct Participant either directly or indirectly ("Indirect
Participants"). The rules applicable to the Depositary and its Participants are
on file with the Commission.
 
     No FELINE PRIDES represented by Global Security Certificates may be
exchanged in whole or in part for FELINE PRIDES registered, and no transfer of
Global Security Certificates in whole or in part may be registered, in the name
of any person other than the Depositary or any nominee of the Depositary unless
the Depositary has notified the Company that it is unwilling or unable to
continue as depositary for such Global Security Certificates or has ceased to be
qualified to act as such as required by the Purchase Contract Agreement or there
shall have occurred and be continuing a default by the Company in respect of its
obligations under one or more Purchase Contracts. All FELINE PRIDES represented
by one or more Global Security Certificates or any portion thereof will be
registered in such names as the Depositary may direct.
 
     As long as the Depositary or its nominee is the registered owner of the
Global Security Certificates, such Depositary or such nominee, as the case may
be, will be considered the sole owner and holder of the Global Security
Certificates and all FELINE PRIDES represented thereby for all purposes under
the FELINE PRIDES and the Purchase Contract Agreement. Except in the limited
circumstances referred to above, owners of beneficial interests in Global
Security Certificates will not be entitled to have such Global Security
Certificates or the FELINE PRIDES represented thereby registered in their names,
will not receive or be entitled to receive physical delivery of FELINE PRIDES
Certificates in exchange therefor and will not be considered to be owners or
holders of such Global Security Certificates or any FELINE PRIDES represented
thereby for any purpose under the FELINE PRIDES or the Purchase Contract
Agreement. All payments on the FELINE PRIDES represented by the Global Security
Certificates and all transfers and deliveries of Trust Preferred Securities,
Treasury Portfolio, Treasury Securities and Common Stock with respect thereto
will be made to the Depositary or its nominee, as the case may be, as the holder
thereof.
 
     Ownership of beneficial interests in the Global Security Certificates will
be limited to Participants or persons that may hold beneficial interests through
institutions that have accounts with the Depositary or its nominee. Ownership of
beneficial interests in Global Security Certificates will be shown only on, and
the transfer of those ownership interests will be effected only through, records
maintained by the Depositary or its nominee (with respect to Participants'
interests) or any such Participant (with respect to interests of persons held by
such Participants on their behalf). Procedures for settlement of Purchase
Contracts on the Purchase Contract
 
                                      S-69
<PAGE>   114
 
Settlement Date or upon Early Settlement will be governed by arrangements among
the Depositary, Participants and persons that may hold beneficial interests
through Participants designed to permit such settlement without the physical
movement of certificates. Payments, transfers, deliveries, exchanges and other
matters relating to beneficial interests in Global Security Certificates may be
subject to various policies and procedures adopted by the Depositary from time
to time. None of the Company, the Purchase Contract Agent or any agent of the
Company or the Purchase Contract Agent will have any responsibility or liability
for any aspect of the Depositary's or any Participant's records relating to, or
for payments made on account of, beneficial interests in Global Security
Certificates, or for maintaining, supervising or reviewing any of the
Depositary's records or any Participant's records relating to such beneficial
ownership interests.

                  CERTAIN PROVISIONS OF THE PURCHASE CONTRACT
                      AGREEMENTS AND THE PLEDGE AGREEMENT
 
GENERAL
 
     Distributions on the FELINE PRIDES will be payable, Purchase Contracts (and
documents related thereto) will be settled and transfers of the FELINE PRIDES
will be registrable at the office of the Purchase Contract Agent in the Borough
of Manhattan, The City of New York. In addition, in the event that the FELINE
PRIDES do not remain in book-entry form, payment of distributions on the FELINE
PRIDES may be made, at the option of the Company, by check mailed to the address
of the person entitled thereto as shown on the Security Register.
 
     Shares of Common Stock will be delivered on the Purchase Contract
Settlement Date, or, if the Purchase Contracts have terminated, the related
Pledged Securities will be delivered potentially after a limited delay as a
result of the imposition of the automatic stay under the Bankruptcy Code (see
"Description of the Purchase Contracts--Termination"), in each case upon
presentation and surrender of the FELINE PRIDES Certificate at the office of the
Purchase Contract Agent. If a holder of outstanding Income PRIDES or Growth
PRIDES fails to present and surrender the FELINE PRIDES Certificate evidencing
such Income PRIDES or Growth PRIDES to the Purchase Contract Agent on the
Purchase Contract Settlement Date, the shares of Common Stock issuable in
settlement of the related Purchase Contract and in payment of any Deferred
Contract Adjustment Payments will be registered in the name of the Purchase
Contract Agent and, together with any distributions thereon, shall be held by
the Purchase Contract Agent as agent for the benefit of such holder, until such
FELINE PRIDES Certificate is presented and surrendered or the holder provides
satisfactory evidence that such certificate has been destroyed, lost or stolen,
together with any indemnity that may be required by the Purchase Contract Agent
and the Company.
 
     If the Purchase Contracts have terminated prior to the Purchase Contract
Settlement Date, the related Pledged Securities have been transferred to the
Purchase Contract Agent for distribution to the holders entitled thereto and a
holder fails to present and surrender the FELINE PRIDES Certificate evidencing
such holder's Income PRIDES or Growth PRIDES to the Purchase Contract Agent, the
related Pledged Securities delivered to the Purchase Contract Agent and payments
thereon shall be held by the Purchase Contract Agent as agent for the benefit of
such holder, until such FELINE PRIDES Certificate is presented or the holder
provides the evidence and indemnity described above.
 
     The Purchase Contract Agent will have no obligation to invest or to pay
interest on any amounts held by the Purchase Contract Agent pending
distribution, as described above.
 
     No service charge will be made for any registration of transfer or exchange
of the FELINE PRIDES, except for any tax or other governmental charge that may
be imposed in connection therewith.
 
MODIFICATION
 
     The Purchase Contract Agreement and the Pledge Agreement will contain
provisions permitting the Company and the Purchase Contract Agent or Collateral
Agent, as the case may be, with the consent of the holders of not less than
66 2/3% of the Purchase Contracts at the time outstanding, to modify the terms
of the Purchase Contracts, the Purchase Contract Agreement and the Pledge
Agreement, except that no such modification may, without the consent of the
holder of each outstanding Purchase Contract affected thereby, (a) change any
Payment Date, (b) change the amount or type of Pledged Securities related to
such Purchase Contract, impair the right of the holder of any Pledged Securities
to receive distributions on such Pledged Securities (except for the rights of
holders of Income PRIDES or Growth PRIDES to substitute Treasury Securities for
the related Trust Preferred Securities or Treasury Portfolio, as the case may
be, or the rights of holders of Growth PRIDES to substitute Trust Preferred
Securities for the related Treasury Securities) or otherwise adversely affect
the holder's rights in or to such Pledged Securities, (c) change the place or
currency of payment or reduce any Contract Adjustment Payments or any Deferred
Contract Adjustment Payments, (d) impair the right to institute suit for the
enforcement of such Purchase Contract, (e) reduce the amount of Common Stock
purchasable under such Purchase Contract, increase the price to purchase Common
Stock on settlement of such Purchase Contract, change the Purchase Contract
Settlement Date or otherwise adversely
 
                                      S-71
<PAGE>   116
 
affect the holder's rights under such Purchase Contract or (f) reduce the
above-stated percentage of outstanding Purchase Contracts the consent of whose
holders is required for the modification or amendment of the provisions of the
Purchase Contracts, the Purchase Contract Agreement or the Pledge Agreement;
provided, that if any amendment or proposal referred to above would adversely
affect only the Income PRIDES or the Growth PRIDES, then only the affected class
of holder will be entitled to vote on such amendment or proposal and such
amendment or proposal shall not be effective except with the consent of the
holders of not less than 66 2/3% of such class.
 
NO CONSENT TO ASSUMPTION
 
     Each holder of Income PRIDES or Growth PRIDES, by acceptance thereof, will
under the terms of the Purchase Contract Agreement and the Income PRIDES or
Growth PRIDES, as applicable, be deemed expressly to have withheld any consent
to the assumption (i.e., affirmance) of the related Purchase Contracts by the
Company or its trustee in the event that the Company becomes the subject of a
case under the Bankruptcy Code.
 
CONSOLIDATION, MERGER, SALE OR CONVEYANCE
 
     The Company will covenant in the Purchase Contract Agreement that it will
not merge or consolidate with any other entity or sell, assign, transfer, lease
or convey all or substantially all of its properties and assets to any person,
firm or corporation unless the Company is the continuing corporation or the
successor corporation is a corporation organized under the laws of the United
States of America or a state thereof and such corporation expressly assumes the
obligations of the Company under the Purchase Contracts, the Debentures, the
Purchase Contract Agreement and the Pledge Agreement, and the Company or such
successor corporation is not, immediately after such merger, consolidation,
sale, assignment, transfer, lease or conveyance, in default in the performance
of any of its obligations thereunder.
 
TITLE
 
     The Company, the Purchase Contract Agent and the Collateral Agent may treat
the registered owner of any FELINE PRIDES as the absolute owner thereof for the
purpose of making payment and settling the related Purchase Contracts and for
all other purposes.
 
REPLACEMENT OF FELINE PRIDES CERTIFICATES
 
     In the event that physical certificates have been issued, any mutilated
FELINE PRIDES Certificate will be replaced by the Company at the expense of the
holder upon surrender of such certificate to the Purchase Contract Agent. FELINE
PRIDES Certificates that become destroyed, lost or stolen will be replaced by
the Company at the expense of the holder upon delivery to the Company and the
Purchase Contract Agent of evidence of the destruction, loss or theft thereof
satisfactory to the Company and the Purchase Contract Agent. In the case of a
destroyed, lost or stolen FELINE PRIDES Certificate, an indemnity satisfactory
to the Purchase Contract Agent and the Company may be required at the expense of
the holder of the FELINE PRIDES evidenced by such certificate before a
replacement will be issued.
 
     Notwithstanding the foregoing, the Company will not be obligated to issue
any Income PRIDES or Growth PRIDES on or after the Purchase Contract Settlement
Date or after the Purchase Contracts have terminated. The Purchase Contract
Agreement will provide that in lieu of the delivery of a replacement FELINE
PRIDES Certificate following the Purchase Contract Settlement Date, the Purchase
Contract Agent, upon delivery of the evidence and indemnity described above,
will deliver the Common Stock issuable pursuant to the Purchase Contracts
included in the Income PRIDES or Growth PRIDES evidenced by such certificate,
or, if the Purchase Contracts have terminated prior to the Purchase Contract
Settlement Date, transfer the principal amount of the Pledged Securities
included in the Income PRIDES or Growth PRIDES evidenced by such certificate.
 
GOVERNING LAW
 
     The Purchase Contract Agreement, the Pledge Agreement and the Purchase
Contracts will be governed by, and construed in accordance with, the laws of the
State of New York.

<PAGE>   117
 
INFORMATION CONCERNING THE PURCHASE CONTRACT AGENT
 
                 will be the Purchase Contract Agent. The Purchase Contract
Agent will act as the agent for the holders of Income PRIDES and Growth PRIDES
from time to time. The Purchase Contract Agreement will not obligate the
Purchase Contract Agent to exercise any discretionary actions in connection with
a default under the terms of the Income PRIDES and Growth PRIDES or the Purchase
Contract Agreement.
 
     The Purchase Contract will contain provisions limiting the liability of the
Purchase Contract Agent. The Purchase Contract Agreement will contain provisions
under which the Purchase Contract Agent may resign or be replaced. Such
resignation or replacement would be effective upon the appointment of a
successor.
 
INFORMATION CONCERNING THE COLLATERAL AGENT
 
                 will be the Collateral Agent. The Collateral Agent will act
solely as the agent of the Company and will not assume any obligation or
relationship of agency or trust for or with any of the holders of the Income
PRIDES and Growth PRIDES except for the obligations owed by a pledgee of
property to the owner thereof under the Pledge Agreement and applicable law.
 
     The Pledge Agreement will contain provisions limiting the liability of the
Collateral Agent. The Pledge Agreement will contain provisions under which the
Collateral Agent may resign or be replaced. Such resignation or replacement
would be effective upon the appointment of a successor.
 
MISCELLANEOUS
 
     The Purchase Contract Agreement will provide that the Company will pay all
fees and expenses related to (i) the offering of the FELINE PRIDES, (ii) the
retention of the Collateral Agent and (iii) the enforcement by the Purchase
Contract Agent of the rights of the holders of the FELINE PRIDES; provided,
however, that holders who elect to substitute the related Pledged Securities,
thereby creating Growth PRIDES or recreating Income PRIDES, shall be responsible
for any fees or expenses payable in connection with such substitution, as well
as any commissions, fees or other expenses incurred in acquiring the Pledged
Securities to be substituted, and the Company shall not be responsible for any
such fees or expenses.

                 DESCRIPTION OF THE TRUST PREFERRED SECURITIES
 
     The Trust Preferred Securities, a certain portion of which form a component
of the Income PRIDES, and which, under certain circumstances, will trade
separately, will be issued pursuant to the terms of the Declaration. See
"Description of the FELINE PRIDES--Substitution of Pledged Securities." The
Declaration will be qualified as an indenture under the Trust Indenture Act. The
Institutional Trustee,             , an independent trustee, will act as
indenture trustee for the Trust Preferred Securities under the Declaration for
purposes of compliance with the provisions of the Trust Indenture Act. The terms
of the Trust Preferred Securities will include those stated in the Declaration
and those made part of the Declaration by the Trust Indenture Act. The following
summary of certain material provisions of the Trust Preferred Securities and the
Declaration is not necessarily complete, and reference is hereby made to the
copy of the Declaration (including the definitions therein of certain terms)
which is filed as an exhibit to the Registration Statement of which this
Prospectus Supplement is a part, the Trust Act and the Trust Indenture Act.
Whenever particular defined terms are referred to in this Prospectus Supplement,
such defined terms are incorporated herein by reference. The following
description of certain terms of the Trust Preferred Securities offered hereby
supplements, and to the extent inconsistent with, replaces the description of
the general terms and provisions of the Trust Preferred Securities set forth in
the accompanying Prospectus, to which reference is hereby made.
 
GENERAL
 
     The Declaration authorizes the Kennametal Trustees to issue on behalf of
the Trust the Trust Securities, which represent undivided beneficial ownership
interests in the assets of the Trust. All of the Common Securities will be
owned, directly or indirectly, by the Company. The Common Securities rank pari
passu, and payments will be made thereon on a pro rata basis, with the Trust
Preferred Securities, except that upon the occurrence and during the continuance
of an Indenture Event of Default, the rights of the holders of the Common
Securities to receive payment of periodic distributions and payments upon
liquidation, redemption and otherwise will be subordinated to the rights of the
holders of the Trust Preferred Securities. The Declaration does not permit the
issuance by the Trust of any securities other than the Trust Securities or the
incurrence of any indebtedness by the Trust. Pursuant to the Declaration, the
Institutional Trustee will hold title to the Debentures purchased by the Trust
for the benefit of the holders of the Trust Securities. The payment of
distributions out of money held by the Trust, and payments upon redemption of
the Trust Preferred Securities or liquidation of the Trust, are guaranteed by
the Company to the extent described under "Description of the Guarantee." The
Guarantee, when taken together with the Company's obligations under the
Debentures and the Indenture and its obligations under the Declaration,
including the obligations to pay costs, expenses, debts and liabilities of the
Trust (other than with respect to the Trust Preferred Securities), provides a
full and unconditional guarantee of amounts due on the Trust Preferred
Securities. The Guarantee will be held by, the Guarantee Trustee, for the
benefit of the holders of the Trust Preferred Securities. The Guarantee does not
cover payment of distributions when the Trust does not have sufficient available
funds to pay such distributions. In such event, the remedy of a holder of Trust
Preferred Securities is to vote to direct the Institutional Trustee to enforce
the Institutional Trustee's rights under the Debentures (except in the limited
circumstances in which the holder may take direct action). See "--Declaration
Events of Default" and "--Voting Rights."
 
DISTRIBUTIONS
 
     Distributions on the Trust Preferred Securities will be fixed initially at
a rate per annum of     % of the stated liquidation amount of $50 per Trust
Preferred Security. Distributions applicable on the Trust Preferred Securities
that remain outstanding on and after the Purchase Contract Settlement Date will
be reset on the third Business Day immediately preceding the Purchase Contract
Settlement Date. See "--Market Rate Reset." Distributions in arrears for more
than one quarter will bear interest thereon at the rate of     % per annum
through and including February 15, 2001 and at the Reset Rate thereafter,
compounded quarterly. The term "distribution" as used herein includes any such
interest payable unless otherwise stated. The amount of distributions payable
for any period will be computed on the basis of a 360-day year of twelve 30-day
months.
 
     Distributions on the Trust Preferred Securities will be cumulative and will
accrue from             , 199 and will be payable quarterly in arrears on
February 16, May 16, August 16, and November 16 each year,
 
                                      S-74
<PAGE>   119
 
commencing February 16, 1998, when, as and if funds are available for payment.
Distributions will be made by the Institutional Trustee, except as otherwise
described below.
 
     The Company has the right under the Indenture to defer payments of interest
on the Debentures by extending the interest payment period from time to time on
the Debentures, which right, if exercised, would defer quarterly distributions
on the Trust Preferred Securities (though such distributions would continue to
accrue interest at the rate of     % per annum through and including February
15, 2003, and at the Reset Rate thereafter) during any such extended interest
payment period. Such right to extend the interest payment period for the
Debentures is limited to a period, in the aggregate, not extending beyond the
maturity date of the Debentures. In the event that the Company exercises this
right, then (a) the Company shall not declare or pay dividends on, make
distributions with respect to, or redeem, purchase or acquire, or make a
liquidation payment with respect to, any of its capital stock (other than (i)
purchases or acquisitions of capital stock of the Company in connection with the
satisfaction by the Company of its obligations under any employee benefit plans
or the satisfaction by the Company of its obligations pursuant to any contract
or security outstanding on the date of such event requiring the Company to
purchase capital stock of the Company, (ii) as a result of a reclassification of
the Company's capital stock or the exchange or conversion of one class or series
of the Company's capital stock for another class or series of the Company's
capital stock, (iii) the purchase of fractional interests in shares of the
Company's capital stock pursuant to the conversion or exchange provisions of
such capital stock or the security being converted or exchanged, (iv) dividends
or distributions in capital stock of the Company and (v) redemptions or
purchases of any rights pursuant to the Rights Agreement or any successor to the
Rights Agreement, and the declaration thereunder of a dividend of rights in the
future), (b) the Company shall not make any payment of interest, principal or
premium, if any, on or repay, repurchase or redeem any debt securities
(including guarantees) issued by the Company that rank junior to such
Debentures, and (c) the Company shall not make any guarantee payments with
respect to the foregoing other than pursuant to the Guarantee or the Common
Securities Guarantee. Prior to the termination of any such Extension Period, the
Company may further extend the interest payment period; provided, that such
Extension Period, together with all such previous and further extensions
thereof, may not extend beyond the maturity date of the Debentures. Upon the
termination of any Extension Period and the payment of all amounts then due, the
Company may select a new Extension Period, subject to the above requirements.
See "Description of the Debentures--Interest" and "--Option to Extend Interest
Payment Period." If distributions are deferred, the deferred distributions and
accrued interest thereon shall be paid to holders of record of the Trust
Preferred Securities as they appear on the books and records of the Trust on the
record date next following the termination of such Extension Period.
 
     Distributions on the Trust Preferred Securities must be paid on the dates
payable to the extent that the Trust has funds available in the Property Account
for the payment of such distributions. The Trust's funds available for
distribution to the holders of the Trust Preferred Securities will be limited to
payments received from the Company on the Debentures. See "Description of the
Debentures." The payment of distributions out of moneys held by the Trust is
guaranteed by the Company to the extent set forth under "Description of the
Guarantee." Distributions on the Trust Preferred Securities will be payable to
the holders thereof, including the Collateral Agent, as they appear on the books
and records of the Trust on the relevant record dates, which, as long as the
Trust Preferred Securities remain in book-entry only form, will be one Business
Day prior to the relevant payment dates. Such distributions will be paid through
the Institutional Trustee who will hold amounts received in respect of the
Debentures in the Property Account for the benefit of the holders of the Trust
Preferred Securities. Subject to any applicable laws and regulations and the
provisions of the Declaration, each such payment will be made as described under
"Book-Entry Only Issuance--The Depository Trust Company" below. In the event
that the Trust Preferred Securities do not continue to remain in book-entry
form, the Regular Trustees shall have the right to select relevant record dates,
which shall be more than one Business Day but less than 60 Business Days prior
to the relevant payment dates. In the event that any date on which distributions
are to be made on the Trust Preferred Securities is not a Business Day, then
payment of the distributions payable on such date will be made on the next
succeeding day which is a Business Day (and without any interest or other
payment in respect of any such delay), except that, if such Business Day is in
the next succeeding calendar year, such payment shall be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on such record date.

MARKET RATE RESET
 
     The applicable quarterly distribution rate on the Trust Preferred
Securities and the interest rate on the related Debentures on and after the
Purchase Contract Settlement Date will be reset on the third Business Day
immediately preceding the Purchase Contract Settlement Date to the Reset Rate,
which will be equal to the sum of the Reset Spread and the rate on the Two-Year
Benchmark Treasury in effect on the third Business Day immediately preceding the
Purchase Contract Settlement Date and will be determined by the Reset Agent as
the rate the Trust Preferred Securities should bear in order for a Trust
Preferred Security to have an approximate market value on the third Business Day
immediately preceding the Purchase Contract Settlement Date of 100.5% of the
Stated Amount, provided that the Company may limit such Reset Rate to be no
higher than the rate on the Two-Year Benchmark Treasury on the Purchase Contract
Settlement Date plus 200 basis points (2%). Such market value may be less than
100.5% if the Reset Spread is limited to a maximum of 2%. The "Two-Year
Benchmark Treasury" shall mean direct obligations of the United States (which
may be obligations traded on a when-issued basis only) having a maturity
comparable to the remaining term to maturity of the Trust Preferred Securities,
as agreed upon by the Company and the Reset Agent. The rate for the Two-Year
Benchmark Treasury will be the bid side rate displayed at 10:00 A.M., New York
City time, on the third Business Day immediately preceding the Purchase Contract
Settlement Date in the Telerate system (or if the Telerate system is (a) no
longer available on the third Business Day immediately preceding the Purchase
Contract Settlement Date or (b) in the opinion of the Reset Agent (after
consultation with the Company) no longer an appropriate system from which to
obtain such rate, such other nationally recognized quotation system as, in the
opinion of the Reset Agent (after consultation with the Company) is
appropriate). If such rate is not so displayed, the rate for the Two-Year
Benchmark Treasury shall be, as calculated by the Reset Agent, the yield to
maturity for the Two-Year Benchmark Treasury, expressed as a bond equivalent on
the basis of a year of 365 or 366 days, as applicable, and applied on a daily
basis, and computed by taking the arithmetic mean of the secondary market bid
rates, as of 10:30 A.M., New York City time, on the third Business Day
immediately preceding the Purchase Contract Settlement Date of three leading
United States government securities dealers selected by the Reset Agent (after
consultation with the Company) (which may include the Reset Agent or an
affiliate thereof). In no event will the Reset Rate be higher than the rate on
the Two-Year Benchmark Treasury on the third Business Day immediately preceding
the Purchase Contract Settlement Date plus 200 basis points (2%). It is
currently anticipated that Merrill Lynch, Pierce, Fenner Smith Incorporated will
be the investment banking firm acting as the Reset Agent.
 
     On the tenth Business Day immediately preceding the Purchase Contract
Settlement Date, the Two-Year Benchmark Treasury to be used to determine the
Reset Rate on the Purchase Contract Settlement Date will be selected and the
Reset Spread to be added to the rate on the Two-Year Benchmark Treasury in
effect on the third Business Day immediately preceding the Purchase Contract
Settlement Date will be established by the Reset Agent, and the Reset Spread and
the Two-Year Benchmark Treasury will be announced by the Company (the "Reset
Announcement Date"). The Company will cause a notice of the Reset Spread and
such Two-Year Benchmark Treasury to be published on the Business Day following
the Reset Announcement Date by publication in a daily newspaper in the English
language of general circulation in The City of New York, which is expected to be
The Wall Street Journal. The Company will request, not later than 7 nor more
than 15 calendar days prior to the Reset Announcement Date, that the Depositary
notify its participants holding Trust Preferred Securities, Income PRIDES or
Growth PRIDES of such Reset Announcement Date and of the procedures that must be
followed if any owner of FELINE PRIDES wishes to settle the related Purchase
Contract with cash on the Business Day immediately preceding the Purchase
Contract Settlement Date.
 
OPTIONAL REDEMPTION
 
     The Debentures are redeemable at the option of the Company, in whole but
not in part, on not less than 30 days nor more than 60 days notice, upon the
occurrence and continuation of a Tax Event under the circumstances described
under "Description of the Debentures--Tax Event Redemption". If the Company
redeems the Debenture, upon the occurrence and continuation of a Tax Event, the
proceeds from such repayment shall simultaneously be applied to redeem Trust
Preferred Securities having an aggregate stated liquidation amount equal to the
aggregate principal amount of the Debentures so redeemed at a Redemption Price,
per Trust Preferred Security, equal to the Redemption Amount plus accrued and
unpaid interest, thereon to the date of such
 
                                      S-76
<PAGE>   121
 
redemption. Such proceeds will be payable in cash to the holders of such Trust
Preferred Securities. If the Tax Event Redemption occurs prior to the Purchase
Contract Settlement Date, the Redemption Price payable to the Collateral Agent,
in liquidation of an Income PRIDES holder's interests in the Trust, will be
simultaneously applied by the Collateral Agent to purchase on behalf of such
holders of the Income PRIDES the Treasury Portfolio. The Treasury Portfolio will
be Pledged with the collateral Agent to secure the obligation of the Income
PRIDES holder to purchase Common Stock under the related Purchase Contracts.
 
PUT OPTION
 
     If a Failed Remarketing has occurred, holders of Trust Securities
(including, following the distribution of the Debentures upon a dissolution of
the Trust as described herein, such Debenture holders), holding such Trust
Securities or Debentures, as the case may be, following the Purchase Contract
Settlement Date will have the right, in the case of Trust Securities, to require
the Trust to put to the Company the related Debentures, or in the case of
Debentures, to put such Debentures directly to the Company on March      , 2001,
upon at least three Business Days' prior notice.
 
REDEMPTION PROCEDURES
 
     If the Trust gives a notice of redemption (which notice will be
irrevocable) in respect of all of the Trust Preferred Securities, then, by 12:00
noon, New York City time, on the redemption date, provided that the Company has
paid to the Institutional Trustee sufficient amount of cash in connection with
the related redemption or maturity of the Debentures, the Trust will irrevocably
deposit with the Depositary, the Purchase Contract Agent or the Collateral
Agent, as applicable, funds sufficient to pay the applicable Redemption Price
and will give the Depositary, the Purchase Contract Agent or the Collateral
Agent, as applicable, irrevocable instructions and authority to pay the
Redemption Price to the holders of the Trust Preferred Securities so called for
redemption. If notice of redemption shall have been given and funds deposited as
required, then, immediately prior to the close of business on the date of such
deposit, distributions will cease to accrue and all rights of holders of such
Trust Preferred Securities so called for redemption will cease, except the right
of the holders of such Trust Preferred Securities to receive the Redemption
Price but without interest on such Redemption Price. In the event that any date
fixed for redemption of Trust Preferred Securities is not a Business Day, then
payment of the Redemption Price payable on such date will be made on the next
succeeding day that is a Business Day (without any interest or other payment in
respect of any such delay), except that, if such Business Day falls in the next
calendar year, such payment will be made on the immediately preceding Business
Day.
 
DISTRIBUTION OF THE DEBENTURES
 
     "Investment Company Event" means that the Regular Trustees shall have
received an opinion from independent counsel experienced in practice under the
1940 Act (as defined below) to the effect that, as a result of the occurrence of
a change in law or regulation or a written change in interpretation or
application of law or regulation by any legislative body, court, governmental
agency or regulatory authority (a "Change in 1940 Act Law"), which Change in
1940 Act Law becomes effective on or after the date of this Prospectus
Supplement, there is more than an insubstantial risk that the Trust is or will
be considered an "investment company" which is required to be registered under
the Investment Company Act of 1940, as amended (the "1940 Act").
 
     If, at any time, an Investment Company Event shall occur and be continuing,
the Trust shall be dissolved, with the result that Debentures with an aggregate
principal amount equal to the aggregate stated liquidation amount of, with an
interest rate identical to the distribution rate of, and accrued and unpaid
interest equal to accrued and unpaid distributions on, the Trust Securities,
would be distributed to the holders of the Trust Securities in liquidation of
such holders' interests in the Trust on a pro rata basis within 90 days
following the occurrence of such Investment Company Event; provided, however,
that such dissolution and distribution shall be conditioned on the Company being
unable to avoid such Investment Company Event within such 90-day period by
taking some ministerial action or pursuing some other similar reasonable measure
that will have no adverse effect on the Trust, the Company or the holders of the
Trust Securities and will involve no material cost. If an Investment Company
Event occurs, Debentures distributable to such holders of Trust Preferred
Securities whose Trust Preferred Securities constitute a component of such
holders Income PRIDES, will be distributed to the
 
                                      S-77
<PAGE>   122
 
Collateral Agent in liquidation of such holder's interest in the Trust. Such
Debentures will be pledged to secure such Income PRIDES holders' obligations to
purchase Common Stock under the Purchase Contracts.
 
     The Company will have the right at any time to dissolve the Trust and,
after satisfaction of liabilities of creditors of the Trust as provided by
applicable law, cause the Debentures to be distributed to the holders of the
Trust Securities. As of the date of any distribution of Debentures upon
dissolution of the Trust, (i) the Trust Preferred Securities will no longer be
deemed to be outstanding, (ii) the Depositary or its nominee, as the record
holder of the Trust Preferred Securities, will receive a registered global
certificate or certificates representing the Debentures to be delivered upon
such distribution, and (iii) any certificates representing Trust Preferred
Securities not held by the Depositary or its nominee will be deemed to represent
Debentures having an aggregate principal amount equal to the aggregate stated
liquidation amount of, with an interest rate identical to the distribution rate
of, and accrued and unpaid interest equal to accrued and unpaid distributions
on, such Trust Preferred Securities until such certificates are presented to the
Company or its agent for transfer or reissuance. Debentures distributable to
such holders of Trust Preferred Securities whose Trust Preferred Securities
constitute a component of such holders' Income PRIDES, will be distributed to
the Collateral Agent in liquidation of the interest of such holders of the Trust
Preferred Securities in the Trust. Such Debentures will be pledged to secure
such Income PRIDES holders' obligations to purchase Common Stock under the
Purchase Contracts.
 
     There can be no assurance as to the market prices for either the Trust
Preferred Securities or the Debentures that may be distributed in exchange for
the Trust Preferred Securities if a dissolution of the Trust were to occur.
Accordingly, the Trust Preferred Securities or such Debentures that an investor
may receive if a dissolution of the Trust were to occur may trade at a discount
to the price that the investor paid to purchase the Trust Preferred Securities.
 
     Subject to applicable law (including, without limitation, United States
federal securities laws) the Company or its subsidiaries may at any time, and
from time to time, purchase outstanding Trust Preferred Securities by tender, in
the open market or by private agreement.
 
LIQUIDATION DISTRIBUTION UPON DISSOLUTION
 
     In the event of any voluntary or involuntary dissolution of the Trust
(unless a Tax Event Redemption has occurred), the then holders of the Trust
Preferred Securities will be entitled to receive out of the assets of the Trust,
after satisfaction of liabilities to creditors, Debentures in an aggregate
principal amount equal to the aggregate stated liquidation amount of, with an
interest rate identical to the distribution rate of, and accrued and unpaid
interest equal to accrued and unpaid distributions on, the Trust Preferred
Securities on a pro rata basis in exchange for such Trust Preferred Securities.
 
     The holders of the Common Securities will be entitled to receive
distributions upon any such dissolution pro rata with the holders of the Trust
Preferred Securities, except that if a Declaration Event of Default has occurred
and is continuing, the Trust Preferred Securities shall have a preference over
the Common Securities with regard to such distributions.
 
     Pursuant to the Declaration, the Trust shall dissolve (i) on           ,
2005, the expiration of the term of the Trust, (ii) upon the bankruptcy of the
Company or the holder of the Common Securities, (iii) upon the filing of a
certificate of dissolution or its equivalent with respect to the Company or the
revocation of the charter of the Company and the expiration of 90 days after the
date of revocation without a reinstatement thereof, (iv) after the receipt by
the Institutional Trustee of written direction from the Company to dissolve the
Trust or the filing of a certificate of dissolution or its equivalent with
respect to the Trust, (v) upon the distribution of Debentures, (vi) upon the
occurrence and continuation of a Tax Event Redemption or (vii) upon the entry of
a decree of a judicial dissolution of the holder of the Common Securities, the
Company or the Trust.
 
DECLARATION EVENTS OF DEFAULT
 
     An event of default under the Indenture (an "Indenture Event of Default")
constitutes an event of default under the Declaration with respect to the Trust
Securities (a "Declaration Event of Default"); provided, that pursuant to the
Declaration, the holder of the Common Securities will be deemed to have waived
any Declaration
 
                                      S-78
<PAGE>   123
 
Event of Default with respect to the Common Securities until all Declaration
Events of Default with respect to the Trust Preferred Securities have been
cured, waived or otherwise eliminated. Until such Declaration Events of Default
with respect to the Trust Preferred Securities have been so cured, waived or
otherwise eliminated, the Institutional Trustee will be deemed to be acting
solely on behalf of the holders of the Trust Preferred Securities and only the
holders of the Trust Preferred Securities will have the right to direct the
Institutional Trustee with respect to certain matters under the Declaration and,
therefore, the Indenture. If a Declaration Event of Default with respect to the
Trust Preferred Securities is waived by holders of Trust Preferred Securities,
such waiver will also constitute the waiver of such Declaration Event of Default
with respect to the Common Securities without any further act, vote or consent
of the holders of the Common Securities. If the Institutional Trustee fails to
enforce its rights under the Debentures in respect of an Indenture Event of
Default after a holder of record of Trust Preferred Securities has made a
written request, such holder of record of Trust Preferred Securities may, to the
fullest extent permitted by applicable law, institute a legal proceeding against
the Company to enforce the Institutional Trustee's rights under the Debentures
without first proceeding against the Institutional Trustee or any other person
or entity. Notwithstanding the foregoing, if a Declaration Event of Default has
occurred and is continuing and such event is attributable to the failure of the
Company to pay interest or principal on the Debentures on the date such interest
or principal is otherwise payable (after giving effect to any right of
deferral), then a holder of Trust Preferred Securities may directly institute a
proceeding after the respective due date specified in the Debentures for
enforcement of payment (a "Direct Action") to such holder directly of the
principal of or interest on the Debentures having a principal amount equal to
the aggregate liquidation amount of the Trust Preferred Securities of such
holder. In connection with such Direct Action, the Company shall have the right
under the Indenture to set off any payment made to such holder of the Company.
The holders of Trust Preferred Securities will not be able to exercise directly
any other remedy available to the holders of the Debentures. See "Effect of
Obligations under the Debentures and the Guarantee."
 
     Upon the occurrence of a Declaration Event of Default, the Institutional
Trustee as the sole holder of the Debentures will have the right under the
Indenture to declare the principal of and interest on the Debentures to be
immediately due and payable. The Company and the Trust are each required to file
annually with the Institutional Trustee an officer's certificate as to its
compliance with all conditions and covenants under the Declaration.
 
VOTING RIGHTS
 
     Except as described herein, under the Trust Act and the Trust Indenture Act
and under "Description of the Guarantee--Modification of the Guarantee;
Assignment," and as otherwise required by law and the Declaration, the holders
of the Trust Preferred Securities will have no voting rights.
 
     Subject to the requirement of the Institutional Trustee obtaining a tax
opinion in certain circumstances set forth in the last sentence of this
paragraph, the holders of a majority in aggregate stated liquidation amount of
the Trust Preferred Securities have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Institutional
Trustee, or direct the exercise of any trust or power conferred upon the
Institutional Trustee under the Declaration, including the right to direct the
Institutional Trustee, as holder of the Debentures, to (i) exercise the remedies
available under the Indenture with respect to the Debentures, (ii) waive any
past Indenture Event of Default that is waivable under Section      of the
Indenture, (iii) exercise any right to rescind or annul a declaration that the
principal of all the Debentures shall be due and payable or (iv) consent to any
amendment, modification or termination of the Indenture or the Debentures where
such consent shall be required; provided, however, that, where a consent or
action under the Indenture would require the consent or act of holders of more
than a majority in principal amount of the Debentures (a "Super-Majority")
affected thereby, only the holders of at least such Super-Majority in aggregate
stated liquidation amount of the Trust Preferred Securities may direct the
Institutional Trustee to give such consent or take such action. The
Institutional Trustee shall notify all holders of the Trust Preferred Securities
of any notice of default received from the Debt Trustee (as defined below) with
respect to the Debentures. Such notice shall state that such Indenture Event of
Default also constitutes a Declaration Event of Default. Except with respect to
directing the time, method and place of conducting a proceeding for a remedy,
the Institutional Trustee shall not take any of the actions described in clauses
(i), (ii) or (iii) above unless the Institutional Trustee has obtained an
opinion of tax counsel experienced in
 
                                      S-79
<PAGE>   124
 
such matters to the effect that, as a result of such action, the Trust will not
fail to be classified as a grantor trust for federal income tax purposes.
 
     In the event the consent of the Institutional Trustee, as the holder of the
Debentures, is required under the Indenture with respect to any amendment,
modification or termination of the Indenture or the Debentures, the
Institutional Trustee shall request the direction of the holders of the Trust
Preferred Securities and the Common Securities with respect to such amendment,
modification or termination and shall vote with respect to such amendment,
modification or termination as directed by a majority in stated liquidation
amount of the Trust Preferred Securities and the Common Securities voting
together as a single class; provided, however, that where a consent under the
Indenture would require the consent of a Super-Majority, the Institutional
Trustee may only give such consent at the direction of the holders of at least
the proportion in stated liquidation amount of the Trust Preferred Securities
and the Common Securities which the relevant Super-Majority represents of the
aggregate principal amount of the Debentures outstanding. The Institutional
Trustee shall not take any such action in accordance with the directions of the
holders of the Trust Preferred Securities and the Common Securities unless the
Institutional Trustee has obtained an opinion of tax counsel experienced in such
matters to the effect that, as a result of such action, the Trust will not fail
to be classified as a grantor trust for United States federal income tax
purposes.
 
     A waiver of an Indenture Event of Default will constitute a waiver of the
corresponding Declaration Event of Default.
 
     Any required approval or direction of holders of Trust Preferred Securities
may be given at a separate meeting of holders of Trust Preferred Securities
convened for such purpose, at a meeting of all of the holders of Trust
Securities or pursuant to written consent. The Regular Trustees will cause a
notice of any meeting at which holders of Trust Preferred Securities are
entitled to vote, or of any matter upon which action by written consent of such
holders is to be taken, to be mailed to each holder of record of Trust Preferred
Securities. Each such notice will include a statement setting forth the
following information: (i) the date of such meeting or the date by which such
action is to be taken; (ii) a description of any resolution proposed for
adoption at such meeting on which such holders are entitled to vote or of such
matter upon which written consent is sought; and (iii) instructions for the
delivery of proxies or consents. No vote or consent of the holders of Trust
Preferred Securities will be required for the Trust to cancel Trust Preferred
Securities or distribute Debentures in accordance with the Declaration.
 
     Notwithstanding that holders of Trust Preferred Securities are entitled to
vote or consent under any of the circumstances described above, any of the Trust
Preferred Securities that are owned at such time by the Company or any entity
directly or indirectly controlling or controlled by, or under direct or indirect
common control with, the Company, shall not be entitled to vote or consent and
shall, for purposes of such vote or consent, be treated as if such Trust
Preferred Securities were not outstanding.
 
     The procedures by which holders of Trust Preferred Securities may exercise
their voting rights are described below. See "--Book-Entry Only Issuance--The
Depository Trust Company" below.
 
     Holders of the Trust Preferred Securities will have no rights to appoint or
remove the Kennametal Trustees, who may be appointed, removed or replaced solely
by the Company as the indirect or direct holder of all of the Common Securities.
 
MODIFICATION OF THE DECLARATION
 
     The Declaration may be modified and amended if approved by the Regular
Trustees (and in certain circumstances the Institutional Trustee or the Delaware
Trustee), provided, that if any proposed amendment provides for, or the Regular
Trustees otherwise propose to effect, (i) any action that would adversely affect
the powers, preferences or special rights of the Trust Securities, whether by
way of amendment to the Declaration or otherwise or (ii) the dissolution of the
Trust other than pursuant to the terms of the Declaration, then the holders of
the Trust Securities voting together as a single class will be entitled to vote
on such amendment or proposal and such amendment or proposal shall not be
effective except with the approval of at least a majority in such stated
liquidation amount of the Trust Securities affected thereby; provided further,
that if any amendment or
 
                                      S-80
<PAGE>   125
 
proposal referred to in clause (i) above would adversely affect only the Trust
Preferred Securities or the Common Securities, then only the affected class will
be entitled to vote on such amendment or proposal and such amendment or proposal
shall not be effective except with the approval of a majority in stated
liquidation amount of such class of securities.
 
     Notwithstanding the foregoing, no amendment or modification may be made to
the Declaration if such amendment or modification would (i) cause the Trust to
be classified as other than a grantor trust for purposes of United States
federal income taxation, (ii) reduce or otherwise adversely affect the powers of
the Institutional Trustee or (iii) cause the Trust to be deemed an "investment
company" which is required to be registered under the 1940 Act.
 
MERGERS, CONSOLIDATIONS OR AMALGAMATIONS
 
     The Trust may not consolidate, amalgamate, merge with or into, or be
replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety, to any corporation or other body, except as
described below or as described in "Liquidation Distribution Upon Dissolution".
The Trust may, with the consent of the Regular Trustees and without the consent
of the holders of the Trust Securities, consolidate, amalgamate, merge with or
into, or be replaced by a trust organized as such under the laws of any State;
provided, that (i) if the Trust is not the surviving entity, such successor
entity either (x) expressly assumes all of the obligations of the Trust under
the Trust Securities or (y) substitutes for the Trust Securities other
securities having substantially the same terms as the Trust Securities (the
"Successor Securities"), so long as the Successor Securities rank the same as
the Trust Securities with respect to distributions and payments upon
liquidation, redemption and otherwise, (ii) the Company expressly acknowledges a
trustee of such successor entity possessing the same powers and duties as the
Institutional Trustee as the holder of the Debentures, (iii) if the Trust
Preferred Securities are listed, any Successor Securities will be listed upon
notification of issuance, on any national securities exchange or with another
organization on which the Trust Preferred Securities are then listed or quoted,
(iv) such merger, consolidation, amalgamation or replacement does not cause the
Trust Preferred Securities (including any Successor Securities) to be downgraded
by any nationally recognized statistical rating organization, (v) such merger,
consolidation, amalgamation or replacement does not adversely affect the rights,
preferences and privileges of the holders of the Trust Securities (including any
Successor Securities) in any material respect (other than with respect to any
dilution of the holders' interest in the new entity), (vi) such successor entity
has a purpose substantially identical to that of the Trust, (vii) prior to such
merger, consolidation, amalgamation or replacement, the Company has received an
opinion of a nationally recognized independent counsel to the Trust experienced
in such matters to the effect that, (A) such merger, consolidation, amalgamation
or replacement does not adversely affect the rights, preferences and privileges
of the holders of the Trust Securities (including any Successor Securities) in
any material respect (other than with respect to any dilution of the holders'
interest in the new entity), (B) following such merger, consolidation,
amalgamation or replacement, neither the Trust nor such successor entity will be
required to register as an investment company under the 1940 Act and (C)
following such merger, consolidation, amalgamation or replacement, the Trust (or
the successor entity) will continue to be classified as a grantor trust for
federal income tax purposes, and (viii) the Company guarantees the obligations
of such successor entity under the Successor Securities at least to the extent
provided by the Guarantee and the Common Securities Guarantee. Notwithstanding
the foregoing the Trust shall not, except with the consent of holders of 100% in
stated liquidation amount of the Trust Securities, consolidate, amalgamate,
merge with or into, or be replaced by any other entity or permit any other
entity to consolidate, amalgamate, merge with or into, or replace it, if such
consolidation, amalgamation, merger or replacement would cause the Trust or the
successor entity to be classified as other than a grantor trust for federal
income tax purposes.
 
BOOK-ENTRY ONLY ISSUANCE--THE DEPOSITORY TRUST COMPANY
 
     In the event that the Trust Preferred Securities are issued as one or more
fully-registered global Trust Preferred Securities certificates representing the
total aggregate number of the Trust Preferred Securities, the Depositary is
designated to act as securities depositary for any Trust Preferred Securities
that are initially issued and held separately from the Income PRIDES or that are
redeemed to holders in connection with the creation of Growth PRIDES. In such
event, the Trust Preferred Securities will be issued only as fully-registered
securities
 
                                      S-81
<PAGE>   126
 
registered in the name of Cede & Co. (the Depositary's nominee). However, under
certain circumstances, the Regular Trustees with the consent of the Company may
decide not to use the system of book-entry transfer, through the DTC with
respect to the Trust Preferred Securities. In such event, certificates of the
Trust Preferred Securities will be printed and delivered to the holders.
 
     The laws of some jurisdictions require that certain purchasers of
securities take physical delivery of securities in definitive form. Such laws
may impair the ability to transfer beneficial interests in the global Trust
Preferred Securities as represented by a global certificate.
 
     Purchases of Trust Preferred Securities within the Depositary's system must
be made by or through Direct Participants, which will receive a credit for the
Trust Preferred Securities on the Depositary's records. The ownership interest
of each actual purchaser of each Trust Preferred Security (a "Beneficial Owner")
is in turn to be recorded on the Direct and Indirect Participants' records.
Beneficial Owners will not receive written confirmation from the Depositary of
their purchases, but Beneficial Owners are expected to receive written
confirmations providing details of the transaction, as well as periodic
statements of their holdings, from the Direct or Indirect Participants through
which the Beneficial Owners purchased Trust Preferred Securities. Transfers of
ownership interests in the Trust Preferred Securities are to be accomplished by
entries made on the books of Participants acting on behalf of Beneficial Owners.
Beneficial owners will not receive certificates representing their ownership
interests in the Trust Preferred Securities, except in the event that use of the
book-entry system for the Trust Preferred Securities is discontinued.
 
     To facilitate subsequent transfers, all the Trust Preferred Securities
deposited by Participants with the Depositary will be registered in the name of
the Depositary's nominee, Cede & Co. The deposit of Trust Preferred Securities
with the Depositary and their registration in the name of Cede & Co. effect no
change in beneficial ownership. The Depositary has no knowledge of the actual
Beneficial Owners of the Trust Preferred Securities. The Depositary's records
reflect only the identity of the Direct Participants to whose accounts such
Trust Preferred Securities are credited, which may or may not be the Beneficial
Owners. The Participants will remain responsible for keeping account of their
holdings on behalf of their customers.
 
     So long as the Depositary or its nominee is the registered owner or holder
of a Global Certificate, the Depositary or such nominee, as the case may be,
will be considered the sole owner or holder of the Trust Preferred Securities
represented thereby for all purposes under the Declaration and the Trust
Preferred Securities. No beneficial owner of an interest in a Global Certificate
will be able to transfer that interest except in accordance with the Depositary
applicable procedures, in addition to those provided for under the Declaration.
 
     The Depositary has advised the Company that it will take any action
permitted to be taken by a holder of Trust Preferred Securities (including the
presentation of Trust Preferred Securities for exchange as described below) only
at the direction of one or more Participants to whose account the Depositary's
interests in the Global Certificates are credited and only in respect of such
portion of the stated liquidation amount of Trust Preferred Securities as to
which such Participant or Participants has or have given such directions.
However, if there is a Declaration Event of Default under the Trust Preferred
Securities, the Depositary will exchange the Global Certificates for
Certificated Securities, which it will distribute to its Participants.
 
     Conveyance of notices and other communications by the Depositary to Direct
Participants and Indirect Participants and by Direct Participants and Indirect
Participants to Beneficial Owners will be governed by arrangements among them,
subject to any statutory or regulatory requirements that may be in effect from
time to time.
 
     Although voting with respect to the Trust Preferred Securities is limited,
in those cases where a vote is required, neither the Depositary nor Cede & Co.
will itself consent or vote with respect to Trust Preferred Securities. Under
its usual procedures, the Depositary would mail an omnibus proxy to the Trust as
soon as possible after the record date. The omnibus proxy assigns Cede & Co.'s
consenting or voting rights to those Direct Participants to whose accounts the
Trust Preferred Securities are credited on the record date (identified in a
listing attached to the omnibus proxy). The Company and the Trust believe that
the arrangements among the Depositary, Direct and Indirect Participants, and
Beneficial Owners will enable the Beneficial Owners to exercise
 
                                      S-82
<PAGE>   127
 
rights equivalent in substance to the rights that can be directly exercised by a
record holder of a beneficial interest in the Trust.
 
     Distribution payments on the Trust Preferred Securities issued in the form
of one or more global certificates will be made to the Depositary in immediately
available funds. The Depositary's practice is to credit Direct Participants'
accounts on the relevant payment date in accordance with their respective
holdings shown on the Depositary's records unless the Depositary has reason to
believe that it will not receive payments on such payment date. Payments by
Participants to Beneficial Owners will be governed by standing instructions and
customary practices, as is the case with securities held for the account of
customers in bearer form or registered in "street name," and such payments will
be the responsibility of such Participant and not of the Depositary, the Trust
or the Company, subject to any statutory or regulatory requirements to the
contrary that may be in effect from time to time. Payment of distributions to
the Depositary is the responsibility of the Trust, disbursement of such payments
to Direct Participants is the responsibility of the Depositary, and disbursement
of such payments to the Beneficial Owners is the responsibility of Direct and
Indirect Participants.
 
     Except as provided herein, a Beneficial Owner in a global Trust Preferred
Security certificate will not be entitled to receive physical delivery of Trust
Preferred Securities. Accordingly, each Beneficial Owner must rely on the
procedures of the Depositary to exercise any rights under the Trust Preferred
Securities.
 
     Although the Depositary has agreed to the foregoing procedure in order to
facilitate transfer of interests in the Global Certificates among Participants,
the Depositary is under no obligation to perform or continue to perform such
procedures and such procedures may be discontinued at any time. None of the
Company, the Trust or any Kennametal Trustee will have any responsibility for
the performance by the Depositary or its Participants or Indirect Participants
under the rules and procedures governing the Depositary. The Depositary may
discontinue providing its services as securities depositary with respect to the
Trust Preferred Securities at any time by giving reasonable notice to the Trust.
Under such circumstances, in the event that a successor securities depositary is
not obtained, Trust Preferred Securities certificates are required to be printed
and delivered to holders. Additionally, the Regular Trustees (with the consent
of the Company) may decide to discontinue use of the system of book-entry
transfers through the Depositary (or any successor depositary) with respect to
the Trust Preferred Securities. In that event, certificates for the Trust
Preferred Securities will be printed and delivered to holders. In each of the
above circumstances, the Company will appoint a paying agent with respect to the
Trust Preferred Securities.
 
     The information in this section concerning the Depositary and the
Depositary's book-entry system has been obtained from sources that the Company
and the Trust believe to be reliable, but neither the Company nor the Trust
takes responsibility for the accuracy hereof.
 
REGISTRAR, TRANSFER AGENT AND PAYING AGENT
 
     Payments in respect of the Trust Preferred Securities represented by the
Global Certificates shall be made to the Depositary, which shall credit the
relevant accounts at the Depositary on the applicable distribution dates, or, in
the case of certificated securities, such payments shall be made by check mailed
to the address of the holder entitled thereto as such address shall appear on
the Register. The Paying Agent shall be permitted to resign as Paying Agent upon
30 days' written notice to the Kennametal Trustees. In the event that
            shall no longer be the Paying Agent, the Regular Trustees shall
appoint a successor to act as Paying Agent (which shall be a bank or trust
company).
 
                 will act as registrar, transfer agent and paying agent for the
Trust Preferred Securities.
 
     Registration of transfers of Trust Preferred Securities will be effected
without charge by or on behalf of the Trust, but upon payment (and the giving of
such indemnity as the Trust or the Company may require) in respect of any tax or
other government charge which may be imposed in relation to it.
 
INFORMATION CONCERNING THE INSTITUTIONAL TRUSTEE
 
     The Institutional Trustee prior to the occurrence of a default with respect
to the Trust Securities and after the curing of any defaults that may have
occurred, undertakes to perform only such duties as are specifically set forth
 
                                      S-83
<PAGE>   128
 
in the Declaration and, after default, shall exercise the same degree of care as
a prudent individual would exercise in the conduct of his or her own affairs.
Subject to such provisions, the Institutional Trustee is under no obligation to
exercise any of the powers vested in it by the Declaration at the request of any
holder of Trust Preferred Securities, unless offered reasonable indemnity by
such holder against the costs, expenses and liabilities which might be incurred
thereby. The holders of Trust Preferred Securities will not be required to offer
such indemnity in the event such holders, by exercising their voting rights,
direct the Institutional Trustee to take any action it is empowered to take
under the Declaration following a Declaration Event of Default. The
Institutional Trustee also serves as trustee under the Guarantee.
 
GOVERNING LAW
 
     The Declaration and the Trust Preferred Securities will be governed by, and
construed in accordance with, the internal laws of the State of Delaware.
 
MISCELLANEOUS
 
     The Regular Trustees are authorized and directed to operate the Trust in
such a way so that the Trust will not be required to register as an "investment
company" under the 1940 Act or be characterized as other than a grantor trust
for federal income tax purposes. The Company is authorized and directed to
conduct its affairs so that the Debentures will be treated as indebtedness of
the Company for federal income tax purposes. In this connection, the Company and
the Regular Trustees are authorized to take any action not inconsistent with
applicable law, the Declaration of Trust, the certificate of trust of the Trust
or the certificate of incorporation of the Company, that each of the Company and
the Regular Trustees determines in its discretion to be necessary or desirable
to achieve such end, as long as such action does not adversely affect the
interests of the holders of the Trust Preferred Securities or vary the terms
thereof.
 
     Holders of the Trust Preferred Securities have no preemptive or similar
rights.

                          DESCRIPTION OF THE GUARANTEE
 
     Set forth below is a summary of information concerning the Guarantee which
will be executed and delivered by the Company for the benefit of the holders
from time to time of Trust Preferred Securities. The Guarantee will be qualified
as an indenture under the Trust Indenture Act.             , an independent
trustee, will act as indenture trustee under the Guarantee (the "Guarantee
Trustee") for the purposes of compliance with the provisions of the Trust
Indenture Act. The terms of the Guarantee will be those set forth in the
Guarantee and those made part of the Guarantee by the Trust Indenture Act. The
following summary is not necessarily complete, and reference is hereby made to
the copy of the form of Guarantee (including the definitions therein of certain
terms) which is filed as an exhibit to the Registration Statement of which this
Prospectus Supplement forms a part, and to the Trust Indenture Act. Whenever
particular defined terms of the Guarantee are referred to in this Prospectus
Supplement, such defined terms are incorporated herein by reference. The
Guarantee will be held by the Guarantee Trustee for the benefit of the holders
of the Trust Preferred Securities.
 
GENERAL
 
     Pursuant to the Guarantee, the Company will irrevocably and unconditionally
agree, to the extent set forth therein, to pay in full on a senior unsecured
basis, to the holders of the Trust Preferred Securities issued by the Trust, the
Guarantee Payments (as defined herein) (except to the extent paid by the Trust),
as and when due, regardless of any defense, right of set-off or counterclaim
which the Trust may have or assert. The following payments or distributions with
respect to Trust Preferred Securities issued by the Trust to the extent not paid
by or on behalf of the Trust (the "Guarantee Payments"), will be subject to the
Guarantee thereon (without duplication): (i) any accrued and unpaid
distributions which are required to be paid on the Trust Preferred Securities,
to the extent the Trust shall have funds available therefor; (ii) the redemption
price, including all accumulated and unpaid distributions to the date of
redemption, of Trust Preferred Securities in respect of which the related
Debentures have been repurchased by the Company on February 16, 2001 or upon the
occurrence of a Tax Event Redemption, to the extent the Trust shall have funds
available therefor; and (iii) upon a voluntary or involuntary dissolution of the
Trust (other than in connection with the distribution of Debentures to the
holders of Trust Preferred Securities), the lesser of (a) the aggregate of the
stated liquidation amount and all accrued and unpaid distributions on such Trust
Preferred Securities to the date of payment, to the extent the Trust has funds
available therefor, and (b) the amount of assets of the Trust remaining
available for distribution to holders of the Trust Preferred Securities in
liquidation of the Trust. The Company's obligation to make a Guarantee Payment
may be satisfied by direct payment of the required amounts by the Company to the
holders of Trust Preferred Securities or by causing the Trust to pay such
amounts to such holders.
 
     The Guarantee will be a full and unconditional guarantee generally on a
senior unsecured basis with respect to the Trust Preferred Securities issued by
the Trust, but will not apply to any payment of distributions except to the
extent the Trust shall have funds available therefor. If the Company does not
make interest payments on the Debentures purchased by the Trust, the Trust will
not pay distributions on the Trust Preferred Securities and will not have funds
available therefor. See "Effect of Obligations under the Debentures and the
Guarantee."
 
     The Guarantee, when taken together with the Company's obligations under the
Debentures, the Indenture, and the Declaration, will have the effect of
providing a full and unconditional guarantee on a senior unsecured basis by the
Company of payments due on the Trust Preferred Securities.
 
     The Company has also agreed separately to irrevocably and unconditionally
guarantee the obligations of the Trust with respect to the Common Securities
(the "Common Securities Guarantee") to the same extent as the Guarantee, except
that upon an Indenture Event of Default, holders of Trust Preferred Securities
shall have priority over holders of Common Securities with respect to
distributions and payments on liquidation, redemption or otherwise.
 
CERTAIN COVENANTS OF THE COMPANY
 
     In the Guarantee, the Company will covenant that, so long as any Trust
Preferred Securities issued by the Trust remain outstanding, if there shall have
occurred any event that would constitute an event of default under the Guarantee
or the Declaration, then (a) the Company shall not declare or pay any dividend
on, make any
 
                                      S-85
<PAGE>   130
 
distributions with respect to, or redeem, purchase, acquire or make a
liquidation payment with respect to, any of its capital stock (other than (i)
purchases or acquisitions of capital stock of the Company in connection with the
satisfaction by the Company of its obligations under any employee benefit plans
or the satisfaction by the Company of its obligations pursuant to any contract
or security outstanding on the date of such event requiring the Company to
purchase capital stock of the Company, (ii) as a result of a reclassification of
the Company's capital stock or the exchange or conversion of one class or series
of the Company's capital stock for another class or series of the Company's
capital stock, (iii) the purchase of fractional interests in shares of the
Company's capital stock pursuant to the conversion or exchange provisions of
such capital stock or the security being converted or exchanged, (iv) dividends
or distributions in capital stock of the Company and (v) redemptions or
purchases of any rights pursuant to the Rights Agreement or any successor to the
Rights Agreement, and the declaration thereunder of a dividend of rights in the
future), (b) the Company shall not make any payment of interest, principal or
premium, if any, on or repay, repurchase or redeem any debt securities issued by
the Company which rank junior to the Debentures and (c) the Company shall not
make any guarantee payments with respect to the foregoing (other than payments
pursuant to the Guarantee or the Common Securities Guarantee).
 
MODIFICATION OF THE GUARANTEE; ASSIGNMENT
 
     Except with respect to any changes which do not adversely affect the rights
of holders of Trust Preferred Securities (in which case no vote will be
required), the Guarantee may be amended only with the prior approval of the
holders of not less than a majority in stated liquidation amount of the
outstanding Trust Preferred Securities issued by the Trust. All guarantees and
agreements contained in the Guarantee shall bind the successors, assigns,
receivers, trustees and representatives of the Company and shall inure to the
benefit of the holders of the Trust Preferred Securities then outstanding.
 
TERMINATION
 
     The Guarantee will terminate (a) upon distribution of the Debentures held
by the Trust to the holders of the Trust Preferred Securities, (b) upon full
payment of the redemption price of all the Trust Preferred Securities in the
event that all of the Debentures are repurchased by the Company upon the
occurrence of a Tax Event Redemption or (c) upon full payment of the amounts
payable in accordance with the Declaration upon liquidation of the Trust. The
Guarantee will continue to be effective or will be reinstated, as the case may
be, if at any time any holder of Trust Preferred Securities must restore payment
of any sums paid under the Trust Preferred Securities or the Guarantee.
 
EVENTS OF DEFAULT
 
     An event of default under the Guarantee will occur upon the failure of the
Company to perform any of its payment or other obligations thereunder.
 
     The holders of a majority in stated liquidation amount of the Trust
Preferred Securities have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Guarantee Trustee in
respect of the Guarantee or to direct the exercise of any trust or power
conferred upon the Guarantee Trustee under the Guarantee. If the Guarantee
Trustee fails to enforce such Guarantee, any holder of Trust Preferred
Securities may institute a legal proceeding directly against the Company to
enforce such holder's rights under the Guarantee, without first instituting a
legal proceeding against the Trust, the Guarantee Trustee or any other person or
entity. The Company waives any right or remedy to require that any action be
brought first against the Trust or any other person or entity before proceeding
directly against the Company.
 
STATUS OF THE GUARANTEE
 
     The Guarantee will constitute a senior unsecured obligation of the Company
and will rank pari passu with all of the Company's other senior unsecured
obligations.
 
     The Guarantee will constitute a guarantee of payment and not of collection
(that is, the guaranteed party may institute a legal proceeding directly against
the guarantor to enforce its rights under the guarantee without instituting a
legal proceeding against any other person or entity).

INFORMATION CONCERNING THE GUARANTEE TRUSTEE
 
     The Guarantee Trustee, prior to the occurrence of a default with respect to
the Guarantee, undertakes to perform only such duties as are specifically set
forth in the Guarantee and, after default, shall exercise the same degree of
care as a prudent individual would exercise in the conduct of his or her own
affairs. Subject to such provisions, the Guarantee Trustee is under no
obligation to exercise any of the powers vested in it by the Guarantee at the
request of any holder of Trust Preferred Securities, unless offered reasonable
indemnity against the costs, expenses and liabilities which might be incurred
thereby; but the foregoing shall not relieve the Guarantee Trustee, upon the
occurrence of an event of default under the Guarantee, from exercising the
rights and powers vested in it by the Guarantee.
 
GOVERNING LAW
 
     The Guarantee will be governed by and construed in accordance with the
internal laws of the State of New York.
 
                                      S-87
<PAGE>   132
 
                         DESCRIPTION OF THE DEBENTURES
 
     Set forth below is a description of the specific terms of the Debentures in
which the Trust will invest the proceeds from the issuance and sale of the Trust
Securities. The following description is not necessarily complete, and reference
is hereby made to the copy of the form of the Indenture to be entered into
between the Company and,           as trustee (the "Debt Trustee"), as
supplemented or amended from time to time (as so supplemented and amended, the
"Indenture"), which is filed as an exhibit to the Registration Statement of
which this Prospectus Supplement forms a part, and to the Trust Indenture Act.
Certain capitalized terms used herein are defined in the Indenture.
 
     Under certain circumstances involving the dissolution of the Trust,
Debentures may be distributed to the holders of the Trust Securities in
liquidation of the Trust. See "Description of the Trust Preferred Securities--
Distribution of the Debentures."
 
GENERAL
 
     The Debentures will be issued as senior unsecured debt under the Indenture
and will rank pari passu in right of payment with all of the Company's other
senior unsecured debt obligations. The Company's obligations with respect to the
Debentures will not be subordinated to any other unsecured debt obligations of
the Company, whether incurred prior to, on or after the date hereof. The
Debentures will be limited in aggregate principal amount to $          , such
amount being the sum of the aggregate stated liquidation amounts of the Trust
Preferred Securities and the Common Securities.
 
     The Debentures will not be subject to a sinking fund provision. Unless a
Tax Event Redemption has occurred, the entire principal amount of the Debentures
will mature and become due and payable, together with any accrued and unpaid
interest thereon including Compound Interest (as defined herein) and expenses
and taxes of the Trust (as defined herein), if any, on February 16, 2003.
 
     The Company will have the right at any time to dissolve the Trust and cause
the Debentures to be distributed to the holders of the Trust Securities. If
Debentures are distributed to holders of Trust Securities in liquidation of such
holders' interests in the Trust, such Debentures will initially be issued as a
Global Security (as defined herein). As described herein, under certain limited
circumstances, Debentures may be issued in certificated form in exchange for a
Global Security. See "-- Book-Entry and Settlement" below. In the event that
Debentures are issued in certificated form, such Debentures will be in
denominations of $50 and integral multiples thereof and may be transferred or
exchanged at the offices described below. Payments on Debentures issued as a
Global Security will be made to the Depositary, a successor depositary or, in
the event that no depositary is used, to a Paying Agent for the Debentures. In
the event Debentures are issued in certificated form, principal and interest
will be payable, the transfer of the Debentures will be registrable and
Debentures will be exchangeable for Debentures of other denominations of a like
aggregate principal amount, at the corporate trust office or agency of the
Institutional Trustee in             ,             ; provided, that at the
option of the Company, payment of interest may be made by check mailed to the
address of the holder entitled thereto or by wire transfer to an account
appropriately designated by the holder entitled thereto. Notwithstanding the
foregoing, so long as the holder of any Debentures is the Institutional Trustee,
the payment of principal and interest on the Debentures held by the
Institutional Trustee will be made at such place and to such account as may be
designated by the Institutional Trustee.
 
     The Indenture does not contain provisions that afford holders of the
Debentures protection in the event of a highly leveraged transaction or other
similar transaction involving the Company that may adversely affect such
holders.
 
INTEREST
 
     Each Debenture shall bear interest initially at the rate of     % per annum
from the original date of issuance, payable quarterly in arrears on February 16,
May 16, August 16 and November 16 of each year (each an "Interest Payment
Date"), commencing February 16, 1998, to the person in whose name such Debenture
is registered, subject to certain exceptions, at the close of business on the
Business Day next preceding such Interest
 
                                      S-88
<PAGE>   133
 
Payment Date. The applicable interest rate on any outstanding Debentures and the
distribution rate on the related Trust Preferred Securities on and after
February 16, 2003 will be reset on the third Business Day immediately preceding
the Purchase Contract Settlement Date to the Reset Rate which will be equal to
the sum of the Reset Spread and the rate on the Two-Year Benchmark Treasury in
effect on the third Business Day immediately preceding the Purchase Contract
Settlement Date and will be determined by the Reset Agent as the rate the Trust
Preferred Securities should bear in order for a Trust Preferred Security to have
an approximate market value on the third Business Day immediately preceding the
Purchase Contract Settlement Date of 100.5% of the Stated Amount, provided that
the Company may limit such Reset Rate to be no higher than the rate on the
Two-Year Benchmark Treasury on the third Business Day immediately preceding
          , 2000 plus 200 basis points (2%). Such market value may be less than
100.5% if the Reset Spread is limited to a maximum of 2%. The "Two-Year
Benchmark Treasury" shall mean direct obligations of the United States (which
may be obligations traded on a when-issued basis only) having a maturity
comparable to the remaining term of the Trust Preferred Securities, as agreed
upon by the Company and the Reset Agent. The rate for the Two-Year Benchmark
Treasury will be the bid side rate displayed at 10:00 A.M., New York City time,
on the third Business Day immediately preceding the Purchase Contract Settlement
Date in the Telerate system (or if the Telerate system is (a) no longer
available on the third Business Day immediately preceding the Purchase Contract
Settlement Date (b) in the opinion of the Reset Agent, no longer an appropriate
system from which to obtain such rate, such other nationally recognized
quotation system as, in the opinion of the Reset Agent (after consultation with
the Company) is appropriate). If such rate is not so displayed, the rate for the
Two-Year Benchmark Treasury shall be, as calculated by the Reset Agent, the
yield to maturity for the Two-Year Benchmark Treasury, expressed as a bond
equivalent on the basis of a year of 365 or 366 days, as applicable, and applied
on a daily basis, and computed by taking the arithmetic mean of the secondary
market bid rates, as of 10:30 A.M., New York City time, on the third Business
Day immediately preceding the Purchase Contract Settlement Date of three leading
United States government securities dealers selected by the Reset Agent (after
consultation with the Company) (which may include the Reset Agent or an
affiliate thereof). It is currently anticipated that Merrill Lynch, Pierce,
Fenner & Smith Incorporated will be the investment banking firm acting as the
Reset Agent.
 
     On the Reset Announcement Date, the Two-Year Benchmark Treasury will be
selected and the Reset Spread to be added to the rate on the Two-Year Benchmark
Treasury in effect on the third Business Day immediately preceding the Purchase
Contract Settlement Date will be established by the Reset Agent, and the Reset
Spread and the Two-Year Benchmark Treasury will be announced by the Company. The
Company will cause a notice of the Reset Spread and such Two-Year Benchmark
Treasury to be published on the Business Day following the Reset Announcement
Date by publication in a daily newspaper in the English language of general
circulation in The City of New York, which is expected to be The Wall Street
Journal. In the event the Debentures shall not continue to remain in book-entry
only form, the Company shall have the right to select record dates, which shall
be more than fifteen Business Days but less than 60 Business Days prior to the
Interest Payment Date.
 
     The amount of interest payable for any period will be computed on the basis
of a 360-day year consisting of twelve 30-day months. The amount of interest
payable for any period shorter than a full quarterly period for which interest
is computed will be computed on the basis of the actual number of days elapsed
in such 90-day period. In the event that any date on which interest is payable
on the Debentures is not a Business Day, then payment of the interest payable on
such date will be made on the next succeeding day that is a Business Day (and
without any interest or other payment in respect of any such delay), except
that, if such Business Day is in the next succeeding calendar year, then such
payment shall be made on the immediately preceding Business Day, in each case
with the same force and effect as if made on such date.
 
TAX EVENT REDEMPTION
 
     If a Tax Event shall occur and be continuing, the Company may, at its
option, redeem Debentures in whole (but not in part) at any time prior to the
Purchase Contract Settlement Date, at a Redemption Price equal to, for each
Debenture, the Redemption Amount plus accrued and unpaid interest thereon,
including Compound Interest and expenses and taxes of the Trust (each as defined
herein), if any, to the date of redemption (the "Tax Event Redemption Date").
If, following the occurrence of a Tax Event, the Company exercises its option to
redeem the Debentures, then the proceeds of such redemption will be applied to
redeem Trust Securities having a liquidation
 
                                      S-89
<PAGE>   134
 
amount equal to the principal amount of Debentures to be paid in accordance with
their terms, at the Redemption Price. Such Redemption Price will be payable in
cash to the holders of such Trust Securities. If such Tax Event Redemption
occurs prior to the Purchase Contract Settlement Date, the Redemption Price
payable in liquidation of the Income PRIDES holders' interest in the Trust will
be distributed to the Collateral Agent, who in turn will apply an amount equal
to the Redemption Amount of such Redemption Price to purchase the Treasury
Portfolio on behalf of the holders of Income PRIDES and remit the remaining
portion, if any, of such Redemption Price to the Purchase Contract Agent for
payment to the holders of such Income PRIDES. Such Treasury Portfolio will be
substituted for the Trust Preferred Securities and will be pledged with the
Collateral Agent to secure such Income PRIDES holders' obligation to purchase
the Company's Common Stock under the Purchase Contracts; provided, that if the
Tax Event Redemption occurs after the Purchase Contract Settlement Date, such
Treasury Portfolio will not be purchased.
 
     "Tax Event" means the receipt by the Trust of an opinion of a nationally
recognized independent tax counsel experienced in such matters to the effect
that, as a result of (a) any amendment to, or change (including any announced
prospective change) in, the laws (or any regulations thereunder) of the United
States or any political subdivision or taxing authority thereof or therein
affecting taxation, (b) any amendment to or change in an interpretation or
application of such laws or regulations by any legislative body, court,
governmental agency or regulatory authority or (c) any interpretation or
pronouncement that provides for a position with respect to such laws or
regulations that differs from the generally accepted position on the date the
Trust Securities are issued, which amendment or change is effective or which
interpretation or pronouncement is announced on or after the date of issuance of
the Trust Securities under the Declaration, there is more than an insubstantial
risk that (i) interest payable by the Company on the Debentures would not be
deductible, in whole or in part, by the Company for federal income tax purposes
or (ii) the Trust would be subject to more than a de minimis amount of other
taxes, duties or other governmental charges.
 
     "Treasury Portfolio" means, with respect to the Applicable Principal Amount
of Debentures (a) if the Tax Event Redemption Date occurs prior to the Purchase
Contract Settlement Date, a portfolio of zero-coupon U.S. Treasury Securities
consisting of (i) interest or principal strips of U.S. Treasury Securities which
mature on or prior to February 15, 2001 in an aggregate amount equal to the
Applicable Principal Amount, and (ii) with respect of each scheduled interest
payment date on the Debentures that occurs after the Tax Event Redemption Date
interest or principal strips of U.S. Treasury Securities which mature on or
prior to such date in an aggregate amount equal to the aggregate interest
payment that would be due on the Applicable Principal Amount of the Debentures
on such date and (b) if the Tax Event Redemption Date occurs after the Purchase
Contract Settlement Date, a portfolio of zero-coupon U.S. Treasury Securities
consisting of (i) interest or principal strips of U.S. Treasury Securities which
mature on or prior to February 15, 2003, in an aggregate amount equal to the
Applicable Principal Amount, and (ii) with respect of each scheduled interest
payment date on the Debentures that occurs after the Tax Event Redemption Date
interest or principal strips of U.S. Treasury Securities which mature on or
prior to such date in an aggregate amount equal to the aggregate interest
payment that would be due on the Applicable Principal Amount of the Debentures
on such date.
 
     "Applicable Principal Amount" means either (i) if the Tax Event Redemption
Date occurs prior to the Purchase Contract Settlement Date, the aggregate
principal amount of the Debentures corresponding to the aggregate stated
liquidation amount of the Trust Preferred Securities which are components of
Income PRIDES on the Tax Event Redemption Date or (ii) if the Tax Event
Redemption occurs on or after the Purchase Contract Settlement Date, the
aggregate principal amount of the Debentures corresponding to the aggregate
stated liquidation amount of the Trust Preferred Securities outstanding on such
Tax Event Redemption Date.
 
     "Redemption Amount" means for each Debenture, the product of the principal
amount of such Debenture and the Treasury Portfolio Purchase Price, expressed as
a percentage of the Applicable Principal Amount.
 
     "Treasury Portfolio Purchase Price" means the lowest aggregate price quoted
by a primary U.S. government securities dealer in New York City (a "Primary
Treasury Dealer") to the Quotation Agent on the third Business Day immediately

     "Quotation Agent" means (i) Merrill Lynch Government Securities, Inc. and
its respective successors, provided, however, that if the foregoing shall cease
to be a Primary Treasury Dealer, the Company shall substitute therefor another
Primary Treasury Dealer, and (ii) any other Primary Treasury Dealer selected by
the Institutional Trustee after consultation with the Company.
 
     Notice of any redemption will be mailed at least 30 days but not more than
60 days before the redemption date to each registered holder of Debentures to be
prepaid at its registered address. Unless the Company defaults in payment of the
Redemption Price, on and after the redemption date interest shall cease to
accrue on such Debentures.
 
PUT OPTION
 
     If a Failed Remarketing has occurred, holders of Trust Securities
(including, following the distribution of the Debentures upon a dissolution of
the Trust as described herein, such Debenture holders), holding such Trust
Securities or Debentures, as the case may be, following the Purchase Contract
Settlement Date will have the right, in the case of Trust Securities, to require
the Trust to put to the Company the related Debentures, or in the case of
Debentures, to put such Debentures directly to the Company on March      , 2001,
upon at least three Business Days' prior notice.
 
OPTION TO EXTEND INTEREST PAYMENT PERIOD
 
     The Company shall have the right at any time, and from time to time, during
the term of the Debentures, to defer payments of interest by extending the
interest payment period for a period not extending beyond the maturity date of
the Debentures, at the end of which Extension Period, the Company shall pay all
interest then accrued and unpaid (including any expenses or taxes of the Trust,
as herein defined) together with interest thereon compounded quarterly at the
rate of     % per annum through and including February 15, 2001, and at the
Reset Rate thereafter, to the extent permitted by applicable law ("Compound
Interest"); provided, that during any such Extension Period, (a) the Company
shall not declare or pay dividends or make any distribution with respect to, or
redeem, purchase, acquire or make a liquidation payment with respect to, any of
its capital stock (other than (i) purchases or acquisitions of capital stock of
the Company in connection with the satisfaction by the Company of its
obligations under any employee benefit plans or the satisfaction by the Company
of its obligations pursuant to any contract or security outstanding on the date
of such event requiring the Company to purchase capital stock of the Company,
(ii) as a result of a reclassification of the Company's capital stock or the
exchange or conversion of one class or series of the Company's capital stock for
another class or series of the Company capital stock, (iii) the purchase of
fractional interests in shares of the Company's capital stock pursuant to the
conversion or exchange provisions of such capital stock or the security being
converted or exchanged, (iv) dividends or distributions in capital stock of the
Company and (v) redemptions or purchases of any rights pursuant to the Rights
Agreement or any successor to the Rights Agreement, and the declaration
thereunder of a dividend of rights in the future), (b) the Company shall not
make any payment of interest, principal or premium, if any, on or repay,
repurchase or redeem any debt securities issued by the Company that rank junior
to the Debentures, and (c) the Company shall not make any guarantee payments
with respect to the foregoing (other than payments pursuant to the Guarantee or
the Common Securities Guarantee). Prior to the termination of any such Extension
Period, the Company may further defer payments of interest by extending the
interest payment period; provided, however, that such Extension Period,
including all such previous and further extensions, may not extend beyond the
maturity of the Debentures. Upon the termination of any Extension Period and the
payment of all amounts then due, the Company may commence a new Extension
Period, subject to the terms set forth in this section. No interest during an
Extension Period, except at the end thereof, shall be due and payable, but the
Company, at its option, may prepay on any Interest Payment Date all of the
interest accrued during the then elapsed portion of an Extension Period. The
Company has no present intention of exercising its right to defer payments of
interest by extending the interest payment period on the Debentures. If the
Institutional Trustee shall be the sole holder of the Debentures, the Company
shall give the Regular Trustees and the Institutional Trustee notice of its
selection of such Extension Period one Business Day prior to the earlier of (i)
the date distributions on the Trust Preferred Securities are payable or (ii) the
date the Regular Trustees are required to give notice, if applicable, to the
NYSE (or other applicable self-regulatory organization) or to holders of the
Trust Preferred Securities of the record or
 
                                      S-91
<PAGE>   136
 
payment date of such distribution. The Regular Trustees shall give notice of the
Company's selection of such Extension Period to the holders of the Trust
Preferred Securities. If the Institutional Trustee shall not be the sole holder
of the Debentures, the Company shall give the holders of the Debentures notice
of its selection of such Extension Period ten Business Days prior to the earlier
of (i) the Interest Payment Date or (ii) the date upon which the Company is
required to give notice, if applicable, to the NYSE (or other applicable
self-regulatory organization) or to holders of the Debentures as of the record
or payment date of such related interest payment.
 
EXPENSES AND TAXES OF THE TRUST
 
     In the Indenture, the Company, as borrower, has agreed to pay all debts and
other obligations (other than with respect to the Trust Securities) and all
costs and expenses of the Trust (including the costs and expenses relating to
the organization of the Trust, the fees and expenses of the Trustees and the
costs and expenses relating to the operation of the Trust) and to pay any and
all taxes and all costs and expenses with respect thereto (other than United
States withholding taxes) to which the Trust might become subject. The Company
also has agreed in the Indenture to execute such additional agreements as may be
necessary or desirable to give full effect to the foregoing.
 
INDENTURE EVENTS OF DEFAULT
 
     If any Indenture Event of Default shall occur and be continuing, the
Institutional Trustee, as the holder of the Debentures, will have the right to
declare the principal of and the interest on the Debentures (including any
Compound Interest and expenses and taxes of the Trust, if any) and any other
amounts payable under the Indenture to be forthwith due and payable and to
enforce its other rights as a creditor with respect to the Debentures.
 
     The following are Events of Default under the Indenture with respect to the
Debentures: (1) failure to pay interest on the Debentures when due, continued
for 30 days; provided, however, that if the Company is permitted by the terms of
the Debentures to defer the payment in question, then the date on which such
payment is due and payable shall be the date on which the Company is required to
make payment following such deferral, if such deferral has been elected pursuant
to the terms of the Debentures; (2) failure to pay the principal of (or premium,
if any, on) the Debentures when due and payable at the stated maturity date,
upon redemption or otherwise; however, if the Company is permitted by the terms
of the Debentures to defer the payment in question, the date on which such
payment is due and payable shall be the date on which the Company is required to
make payment following such deferral, if such deferral has been elected pursuant
to the terms of the Debentures; (3) failure to observe or perform in any
material respect certain other covenants contained in the Indenture, continued
for a period of 90 days after written notice has been given to the Company by
the Debt Trustee or holders of at least 25% in aggregate principal amount of the
outstanding Debentures; and (4) certain events of bankruptcy, insolvency or
reorganization relating to the Company.
 
     The Indenture provides that the Debt Trustee shall, within 30 days after
the occurrence of any Default or Event of Default with respect to the
Debentures, give the holders of the Debentures notice of all uncured Defaults or
Events of Default known to it (the term "Default" includes any event which after
notice or passage of time or both would be an Event of Default); provided,
however, that, except in the case of an Event of Default or a Default in a
payment on the Debentures, the Debt Trustee shall be protected in withholding
such notice so long as the board of directors, the executive committee or
directors or responsible officers of the Debt Trustee in good faith determine
that the withholding of such notice is in the interest of the holders of the
Debentures.
 
     If an Event of Default with respect to the Debentures occurs and is
continuing, the Debt Trustee or the holders of at least 25% in aggregate
principal amount of the outstanding Debentures, by notice in writing to the
Company (and to the Debt Trustee if given by the holders of at least 25% in
aggregate principal amount of the Debentures), may declare the unpaid principal
of and accrued interest to the date of acceleration on all the outstanding
Debentures to be due and payable immediately and, upon any such declaration, the
Debentures shall become immediately due and payable.
 
                                      S-92
<PAGE>   137
 
     In addition, in the case of the Debentures held by the Trust, if an Event
of Default has occurred and is continuing and such event is attributable to the
failure of the Company to pay interest or principal, then a holder of Trust
Preferred Securities may directly institute a proceeding against the Company for
payment.
 
     Any such declaration with respect to the Debentures may be annulled and
past Events of Default and Defaults (except, unless theretofore cured, an Event
of Default or a Default in payment of principal of or interest on the
Debentures) may be waived by the holders of a majority of the principal amount
of the outstanding Debentures, upon the conditions provided in the Indenture.
 
     The Indenture provides that the Company shall periodically file statements
with the Debt Trustee regarding compliance by the Company with certain of the
respective covenants thereof and shall specify any Event of Default or Defaults
with respect to the Debentures, in performing such covenants, of which the
signers may have knowledge.
 
     An Indenture Event of Default also constitutes a Declaration Event of
Default. The holders of Trust Preferred Securities in certain circumstances have
the right to direct the Institutional Trustee to exercise its rights as the
holder of the Debentures. See "Description of the Trust Preferred
Securities--Declaration Events of Default" and "--Voting Rights."
Notwithstanding the foregoing, if an Event of Default has occurred and is
continuing and such event is attributable to the failure of the Company to pay
interest or principal on the Debentures on the date such interest or principal
is otherwise payable, the Company acknowledges that a holder of Trust Preferred
Securities may directly institute a proceeding for enforcement of payment to
such holder directly of the principal of and interest on the Debentures having a
principal amount equal to the aggregate stated liquidation amount of the Trust
Preferred Securities of such holder after the respective due date specified in
the Debentures. In connection with such action, the Company shall have the right
under the Indenture to set-off any payment made to such holder by the Company.
The holders of Trust Preferred Securities will not be able to exercise directly
any other remedy available to the holders of the Debentures.
 
BOOK-ENTRY AND SETTLEMENT
 
     If distributed to holders of Trust Preferred Securities in connection with
the involuntary or voluntary dissolution of the Trust, the Debentures will be
issued in the form of one or more global certificates (each a "Global Security")
registered in the name of the Depositary or its nominee. Except under the
limited circumstances described below, Debentures represented by the Global
Security will not be exchangeable for, and will not otherwise be issuable as,
Debentures in certificated form. The Global Securities described above may not
be transferred except by the Depositary to a nominee of the Depositary or by a
nominee of the Depositary to the Depositary or another nominee of the Depositary
or to a successor depositary or its nominee.
 
     The laws of some jurisdictions require that certain purchasers of
securities take physical delivery of such securities in certificated form. Such
laws may impair the ability to transfer beneficial interests in such a Global
Security.
 
     Except as provided below, owners of beneficial interests in such a Global
Security will not be entitled to receive physical delivery of Debentures in
certificated form and will not be considered the holders (as defined in the
Indenture) thereof for any purpose under the Indenture, and no Global Security
representing Debentures shall be exchangeable, except for another Global
Security of like denomination and tenor to be registered in the name of the
Depositary or its nominee or to a successor Depositary or its nominee.
Accordingly, each Beneficial Owner must rely on the procedures of the Depositary
or if such person is not a Participant, on the procedures of the Participant
through which such person owns its interest to exercise any rights of a holder
under the Indenture.
 
THE DEPOSITARY
 
     If Debentures are distributed to holders of Trust Preferred Securities in
liquidation of such holders' interests in the Trust, the Depositary will act as
securities depositary for the Debentures. For a description of the Depositary
and the specific terms of the depositary arrangements, see "Description of the
Trust Preferred Securities--Book-Entry Only Issuance--The Depository Trust
Company." As of the date of this Prospectus Supplement, the description therein
of the Depositary's book-entry system and the Depositary's practices as they
 
                                      S-93
<PAGE>   138
 
relate to purchases, transfers, notices and payments with respect to the Trust
Preferred Securities apply in all material respects to any debt obligations
represented by one or more Global Securities held by the Depositary. The Company
may appoint a successor to the Depositary or any successor depositary in the
event the Depositary or such successor depositary is unable or unwilling to
continue as a depositary for the Global Securities.
 
     None of the Company, the Trust, the Institutional Trustee, any paying agent
and any other agent of the Company or the Debt Trustee will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests in a Global Security
for such Debentures or for maintaining, supervising or reviewing any records
relating to such beneficial ownership interests.
 
     A Global Security shall be exchangeable for Debentures registered in the
names of persons other than the Depositary or its nominee only if (i) the
Depositary notifies the Company that it is unwilling or unable to continue as a
depositary for such Global Security and no successor depositary shall have been
appointed, (ii) the Depositary at any time, ceases to be a clearing agency
registered under the Exchange Act at which time the depositary is required to be
so registered to act as such depositary and no successor depositary shall have
been appointed, (iii) the Company, in its sole discretion, determines that such
Global Security shall be so exchangeable or (iv) there shall have occurred an
Indenture Event of Default with respect to such Debentures. Any Global Security
that is exchangeable pursuant to the preceding sentence shall be exchangeable
for Debentures registered in such names as the Depositary shall direct. It is
expected that such instructions will be based upon directions received by the
Depositary from its Participants with respect to ownership of beneficial
interests in such Global Security.
 
GOVERNING LAW
 
     The Indenture and the Debentures will be governed by, and construed in
accordance with, the internal laws of the State of New York.
 
MISCELLANEOUS
 
     The Company will pay all fees and expenses related to (i) the offering of
the Trust Securities and the Debentures, (ii) the organization, maintenance and
dissolution of the Trust, (iii) the retention of the Kennametal Trustees and
(iv) the enforcement by the Institutional Trustee of the rights of the holders
of the Trust Preferred Securities. The payment of such fees and expenses will be
fully and unconditionally guaranteed by the Company.

                        EFFECT OF OBLIGATIONS UNDER THE
                          DEBENTURES AND THE GUARANTEE
 
     As set forth in the Declaration, the sole purpose of the Trust is to issue
the Trust Securities evidencing undivided beneficial interests in the assets of
the Trust, and to invest the proceeds from such issuance and sale in the
Debentures and engage in only those other activities necessary or incidental
thereto.
 
     As long as payments of interest and other payments are made when due on the
Debentures, such payments will be sufficient to cover distributions and payments
due on the Trust Securities because of the following factors: (i) the aggregate
principal amount of Debentures will be equal to the sum of the aggregate stated
liquidation amount of the Trust Securities; (ii) the interest rate and the
interest and other payment dates on the Debentures will match the distribution
rate and distribution and other payment dates for the Trust Securities; (iii)
the Company shall pay, and the Trust shall not be obligated to pay, directly or
indirectly, all costs, expenses, debts, and obligations of the Trust (other than
with respect to the Trust Securities); and (iv) the Declaration further provides
that the Kennametal Trustees shall not take or cause or permit the Trust to,
among other things, engage in any activity that is not consistent with the
purposes of the Trust.
 
     Payments of distributions (to the extent funds therefor are available) and
other payments due on the Trust Preferred Securities (to the extent funds
therefor are available) are guaranteed by the Company as and to the extent set
forth under "Description of the Guarantee." If the Company does not make
interest payments on the Debentures purchased by the Trust, the Trust will not
have sufficient funds to pay distributions on the Trust Preferred Securities.
The Guarantee does not apply to any payment of distributions unless and until
the Trust has sufficient funds for the payment of such distributions.
 
     If the Company fails to make interest or other payments on the Debentures
when due (taking account of any Extension Period), the Declaration provides a
mechanism whereby the holders of the Trust Preferred Securities, using the
procedures described in "Description of the Trust Preferred
Securities--Book-Entry Only Issuance-- The Depository Trust Company" and
"--Voting Rights," may direct the Institutional Trustee to enforce its rights
under the Indenture. If the Institutional Trustee fails to enforce its rights
under the Indenture in respect of an Indenture Event of Default, such holder of
record of Trust Preferred Securities may, to the fullest extent permitted by
applicable law, institute a legal proceeding against the Company to enforce the
Institutional Trustee's rights under the Indenture without first instituting any
legal proceeding against the Institutional Trustee or any other person or
entity. Notwithstanding the foregoing, if a Declaration Event of Default has
occurred and is continuing and such event is attributable to the failure of the
Company to pay interest or principal on the Debentures on the date such interest
or principal is otherwise payable, then a holder of Trust Preferred Securities
may directly institute a proceeding against the Company for payment. The
Company, under the Guarantee, acknowledges that the Guarantee Trustee shall
enforce the Guarantee on behalf of the holders of the Trust Preferred
Securities. If the Company fails to make payments under the Guarantee, the
Guarantee provides a mechanism whereby the holders of the Trust Preferred
Securities may direct the Guarantee Trustee to enforce its rights thereunder.
Notwithstanding the foregoing, if the Company has failed to make a payment under
the Guarantee, any holder of Trust Preferred Securities may institute a legal
proceeding directly against the Company to enforce its rights under the
Guarantee without first instituting a legal proceeding against the Trust, the
Guarantee Trustee, or any other person or entity.
 
     The Guarantee, when taken together with the Company's obligations under the
Debentures and the Indenture and its obligations under the Declaration,
including its obligations to pay costs, expenses, debts and liabilities of the
Trust (other than with respect to the Trust Securities), has the effect of
providing a full and unconditional guarantee of amounts due on the Trust
Preferred Securities. See "Description of Guarantee."

                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     The following is a summary of certain of the material United States federal
income tax consequences of the purchase, ownership and disposition of FELINE
PRIDES, Trust Preferred Securities and Common Stock acquired under a Purchase
Contract. Unless otherwise stated, this summary applies only to "U.S. Holders"
who purchased Income PRIDES upon original issuance for an amount equal to the
Stated Amount thereof. A "U.S. Holder" is (i) a person who is a citizen or
resident of the United States, (ii) a corporation or partnership created or
organized in or under the laws of the United States or any state thereof or the
District of Columbia, (iii) an estate the income of which is subject to United
States federal income taxation, regardless of its source, or (iv) a trust if a
court within the United States is able to exercise primary supervision over the
administration of such trust and one or more United States persons have the
authority to control all substantial decisions of such trust. The tax treatment
of a holder may vary depending on such holder's particular situation. This
summary does not deal with special classes of holders such as banks, thrifts,
real estate investment trusts, regulated investment companies, insurance
companies, dealers in securities or currencies, tax-exempt investors, or persons
that will hold FELINE PRIDES, Trust Preferred Securities or Common Stock
acquired under a Purchase Contract as a position in a "straddle," as part of a
"synthetic security" or "hedge," as part of a "conversion transaction" or other
integrated investment, or as other than a capital asset. This summary does not
address the tax consequences to persons that have a functional currency other
than the U.S. dollar or the tax consequences to shareholders, partners or
beneficiaries of a holder of FELINE PRIDES, Trust Preferred Securities or Common
Stock acquired pursuant to a Purchase Contract. Further, it does not include any
description of any alternative minimum tax consequences or the tax laws of any
state, local or foreign government that may be applicable. PROSPECTIVE INVESTORS
THAT ARE NOT UNITED STATES PERSONS (WITHIN THE MEANING OF SECTION 7701(a)(30) OF
THE CODE) ARE URGED TO CONSULT THEIR OWN TAX ADVISORS REGARDING THE UNITED
STATES FEDERAL INCOME TAX CONSEQUENCES OF AN INVESTMENT IN FELINE PRIDES,
INCLUDING THE POTENTIAL APPLICATION OF UNITED STATES WITHHOLDING TAXES.
 
     This summary is based upon the Internal Revenue Code of 1986, as amended
(the "Code"), Treasury regulations (including proposed Treasury regulations)
issued thereunder, Internal Revenue Service ("IRS") rulings and pronouncements
and judicial decisions now in effect, all of which are subject to change,
possibly on a retroactive basis. Any such changes may be applied retroactively
in a manner that could cause the tax consequences to vary substantially from the
consequences described below, possibly adversely affecting a U.S. Holder.
 
     No statutory, administrative or judicial authority directly addresses the
treatment of FELINE PRIDES or instruments similar to FELINE PRIDES for United
States federal income tax purposes. As a result, no assurance can be given that
the IRS will agree with the tax consequences described herein. PROSPECTIVE
INVESTORS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THE TAX
CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE FELINE
PRIDES IN LIGHT OF THEIR OWN PARTICULAR CIRCUMSTANCES, INCLUDING THE TAX
CONSEQUENCES UNDER STATE, LOCAL, FOREIGN AND OTHER TAX LAWS AND THE POSSIBLE
EFFECTS OF CHANGES IN UNITED STATES FEDERAL OR OTHER TAX LAWS.
 
INCOME PRIDES
 
     Allocation of Purchase Price.  A U.S. Holder's acquisition of Income PRIDES
will be treated as an acquisition of a unit consisting of the Trust Preferred
Security and the Purchase Contract constituting such Income PRIDES. The purchase
price of each Income PRIDES will be allocated between the Trust Preferred
Security and the Purchase Contract constituting such Income PRIDES in proportion
to their respective fair market values at the time of purchase. Such allocation
will establish the U.S. Holder's initial tax basis in the Trust Preferred
Security and the Purchase Contract. The Company will report the fair market
value of each Trust Preferred Security as $          and the fair market value
of each Purchase Contract as $          . This position will be binding upon
each U.S. Holder (but not on the IRS) unless such U.S. Holder explicitly
discloses a contrary position on a statement attached to such U.S. Holder's
timely filed United States federal income tax return for the taxable year in
which an Income PRIDES is acquired. Thus, absent such disclosure, a U.S. Holder
should allocate the purchase price for an Income PRIDES in accordance with the
foregoing. The remainder of
 
                                      S-96
<PAGE>   141
 
this discussion assumes that this allocation of the purchase price will be
respected for United States federal income tax purposes.
 
     TRUST PREFERRED SECURITIES
 
     Ownership of Trust Preferred Securities.  A U.S. Holder will be treated as
owning the Trust Preferred Securities constituting a part of the Income PRIDES.
The Company and, by acquiring FELINE PRIDES, each U.S. Holder agrees to treat
such U.S. Holder as the owner, for United States federal, state and local income
and franchise tax purposes, of the Trust Preferred Securities constituting a
part of the Income PRIDES beneficially owned by such U.S. Holder. The remainder
of this summary will assume that U.S. Holders of Income PRIDES will be treated
as the owners of the Trust Preferred Securities constituting a part of such
Income PRIDES for United States federal income tax purposes.
 
     Classification of the Trust.  In connection with the issuance of the FELINE
PRIDES, Buchanan Ingersoll Professional Corporation ("Tax Counsel") will deliver
an opinion that, under current law and assuming compliance with the terms of the
Declaration, and based on certain facts and assumptions contained in such
opinion, the Trust will be classified as a grantor trust and not as an
association taxable as a corporation for United States federal income tax
purposes. As a result, each U.S. Holder of Trust Preferred Securities will be
treated as owning an undivided beneficial ownership interest in the Debentures.
Accordingly, each U.S. Holder of Trust Preferred Securities will be required to
include in its gross income its pro rata share of the interest income or
original issue discount that is paid or accrued on the Debentures. See
"--Interest Income and Original Issue Discount."
 
     Classification of the Debentures.  The Company, the Trust and, by acquiring
FELINE PRIDES, each U.S. Holder agree to treat the Debentures as indebtedness of
the Company for all United States tax purposes. In connection with the issuance
of the Debentures, Tax Counsel will deliver an opinion that, under current law,
and based on certain representations, facts and assumptions set forth in such
opinion, the Debentures will be classified as indebtedness for United States
federal income tax purposes.
 
     Interest Income and Original Issue Discount.  Subject to the discussion
below regarding the Company's right to defer payments of interest on the
Debentures, the Debentures should be treated as "reset bonds" under applicable
Treasury regulations, and interest on the Debentures should not constitute
contingent interest for purposes of the "original issue discount" ("OID") rules.
Under the Treasury regulations applicable to reset bonds, the Debentures should
be treated, solely for purposes of calculating the accrual of OID, as maturing
on the day immediately preceding the Purchase Contract Settlement Date for an
amount equal to 100.5% of the Stated Amount (the "Reset Amount") and as having
been reissued on the Purchase Contract Settlement Date for the Reset Amount. If
the amount of the initial purchase price for the FELINE PRIDES allocated to the
Trust Preferred Securities is less than the Reset Amount, the Debentures should
be treated as having been issued with OID equal to the difference between the
Reset Amount and the amount so allocated to the Trust Preferred Securities,
unless such difference is less than three-fourths of one-percent of the Reset
Amount. If the Debentures were treated as issued with OID, a U.S. Holder would
be required to include such OID in income on an economic accrual basis over the
period between the issue date and the day immediately preceding the Purchase
Contract Settlement Date regardless of such U.S. Holder's method of tax
accounting. Consequently, each U.S. Holder (including those using the cash basis
of accounting) would be required to include OID in its gross income even though
the Company will not actually make current cash payments with respect to such
OID. Any amount of OID included in a U.S. Holder's gross income will increase
such U.S. Holder's tax basis in its Trust Preferred Securities. In addition, a
U.S. Holder should include stated interest on the Debentures in income as
ordinary income when paid to the Trust or accrued, in accordance with such U.S.
Holder's regular method of accounting.
 
     Under the Indenture, the Company has the right to defer payments of
interest on the Debentures. The Company's right to defer payments of interest
could cause the Debentures to be subject to the OID rules. The Company, however,
believes, and intends to take the position, that as of the issue date, the terms
and conditions of the Debentures (in particular the restrictions on the
Company's ability to pay dividends during an Extension Period) make the
likelihood that the Company would exercise its option to defer the payment of
interest a
 
                                      S-97
<PAGE>   142
 
"remote" contingency for these purposes. If so treated, except as provided
below, the Debentures would not be subject to the OID rules as a result of the
Company's right to defer payments of interest on the Debentures.
 
     If the Company were to exercise its right to defer payments of interest,
the Debentures would at that time be treated, solely for purposes of the OID
rules, as reissued with OID. In such event, all of a U.S. Holder's taxable
interest income with respect to the Debentures would thereafter be accounted for
on an economic accrual basis regardless of such U.S. Holder's method of tax
accounting, and actual distributions of stated interest would not be reported as
taxable income. Consequently, each U.S. Holder (including those using the cash
basis of accounting) would be required to include OID in its gross income even
though the Company would not make actual cash payments during an Extension
Period. Any amount of OID included in a U.S. Holder's gross income would
increase such U.S. Holder's tax basis in its Trust Preferred Securities, and the
amount of distributions received by a U.S. Holder with respect to such Trust
Preferred Securities would reduce the tax basis of such Trust Preferred
Securities.
 
     The IRS could take the position that the likelihood that the Company would
exercise its right to defer payments of interest is not a "remote" contingency
for these purposes, in which case U.S. Holders would be required to accrue OID
on the Debentures on an economic accrual basis under the OID rules described in
the preceding paragraph.
 
     U.S. Holders that are corporations will not be entitled to a
dividends-received deduction with respect to any income recognized with respect
to the Trust Preferred Securities.
 
     Distribution of Debentures to U.S. Holders of Trust Preferred Securities.
 A distribution by the Trust of the Debentures as described under the caption
"Description of the Trust Preferred Securities--Liquidation Distribution Upon
Dissolution" will be non-taxable to U.S. Holders. In such event, a U.S. Holder
will have an aggregate tax basis in the Debentures received in the liquidation
equal to the aggregate tax basis such U.S. Holder had in its Trust Preferred
Securities surrendered therefor, and the holding period of such Debentures would
include the period during which such U.S. Holder had held the Trust Preferred
Securities. A U.S. Holder will continue to include interest (or OID) in respect
of Debentures received from the Trust in the manner described under "--Interest
Income and Original Issue Discount."
 
     Sales, Exchanges or Other Dispositions of Trust Preferred Securities.  Gain
or loss will be recognized by a U.S. Holder on a sale, exchange, redemption or
other taxable disposition (collectively, a "disposition") of a Trust Preferred
Security (including a redemption for cash or the remarketing thereof in
satisfaction of the U.S. Holder's obligations pursuant to a Purchase Contract)
in an amount equal to the difference between the amount realized by the U.S.
Holder on the disposition of the Trust Preferred Securities (except to the
extent that such amount realized is characterized as a payment in respect of
accrued by unpaid interest on such U.S. Holder's allocable share of the
Debentures that such U.S. Holder has not included in gross income previously)
and the U.S. Holder's adjusted tax basis in the Trust Preferred Security.
Selling expenses incurred by a U.S. Holder, including the remarketing fee, will
reduce the amount of gain or increase the amount of loss recognized by such U.S.
Holder upon the sale, exchange or other disposition of Trust Preferred
Securities. Gain or loss realized by a U.S. Holder on a disposition of a Trust
Preferred Security may be long-term capital gain depending on the holding period
of the Trust Preferred Security. Capital gains of individuals are eligible for
reduced rates of taxation depending upon the holding period of such capital
assets. The deductibility of capital losses is subject to limitations.
 
     PURCHASE CONTRACTS
 
     Income From Contract Adjustment Payments and Deferred Contract Adjustment
Payments.  There is no direct authority addressing the treatment of the Contract
Adjustment Payments and Deferred Contract Adjustment Payments, if any, under
current law, and such treatment is unclear. Contract Adjustment Payments and
Deferred Contract Adjustment Payments, if any, may constitute taxable income to
a U.S. Holder when received or accrued, in accordance with the U.S. Holder's
method of tax accounting. To the extent the Company is required to file
information returns with respect to Contract Adjustment Payments or Deferred
Contract Adjustment Payments, it intends to report such payments as taxable
income to each U.S. Holder. U.S. Holders should consult their own tax advisors
concerning the treatment of Contract Adjustment Payments and Deferred Contract
Adjustment Payments, including the possibility that any such payment may be
treated as a loan, purchase price adjustment,
 
                                      S-98
<PAGE>   143
 
rebate or payment analogous to an option premium, rather than being includible
in income on a current basis. The Company does not intend to deduct the Contract
Adjustment Payments or Deferred Contract Adjustment Payments, if any, because it
views them as a cost of issuing the Common Stock. The treatment of Contract
Adjustment Payments and Deferred Contract Adjustment Payments could affect a
U.S. Holder's tax basis in a Purchase Contract or Common Stock received under a
Purchase Contract or the amount realized by a U.S. Holder upon the sale or
disposition of a FELINE PRIDES or the termination of a Purchase Contract. See
"--Acquisition of Common Stock under a Purchase Contract," "--Sale or
Disposition of FELINE PRIDES" and "--Termination of Purchase Contract."
 
     Acquisition of Common Stock Under a Purchase Contract.  A U.S. Holder
generally will not recognize gain or loss on the purchase of Common Stock under
a Purchase Contract, except with respect to any cash paid in lieu of a
fractional share of Common Stock. Subject to the following discussion, a U.S.
Holder's aggregate initial tax basis in the Common Stock received under a
Purchase Contract generally should equal the purchase price paid for such Common
Stock plus such U.S. Holder's tax basis in the Purchase Contract (if any), less
the portion of such purchase price and tax basis allocable to the fractional
share. Payments of Contract Adjustment Payments or Deferred Contract Adjustment
Payments that have been received in cash by a U.S. Holder but not included in
income by such U.S. Holder should reduce such U.S. Holder's tax basis in the
Purchase Contract or the Common Stock to be received thereunder (see "--Income
from Contract Adjustment Payments and Deferred Contract Adjustment Payments"
above). The holding period for Common Stock received under a Purchase Contract
will commence on the day after the acquisition of such Common Stock.
 
     Ownership of Common Stock Acquired Under the Purchase Contract.  Any
dividend on Common Stock paid by the Company out of its current or accumulated
earnings and profits (as determined for United States federal income tax
purposes) will be includible in income by the U.S. Holder when accrued or
received in accordance with the U.S. Holder's method of tax accounting. Any such
dividend will be eligible for the dividends received deduction if received by an
otherwise qualifying corporate U.S. Holder that meets the holding period and
other requirements for the dividends received deduction.
 
     Upon a disposition of Common Stock, a U.S. Holder generally will recognize
capital gain or loss equal to the difference between the amount realized and
such U.S. Holder's adjusted tax basis in the Common Stock. Such gain or loss may
be long-term capital gain or loss depending on the holding period of the Common
Stock. Capital gains of individuals are eligible for reduced rates of taxation
depending upon the holding period of such capital assets. The deductibility of
capital losses is subject to limitations.
 
     Early Settlement of Purchase Contract.  A U.S. Holder will not recognize
gain or loss on the receipt of such U.S. Holder's proportionate share of Trust
Preferred Securities or Treasury Securities upon Early Settlement of a Purchase
Contract and will have the same tax basis in such Trust Preferred Securities or
Treasury Securities as before such Early Settlement.
 
     Termination of Purchase Contract.  If a Purchase Contract terminates, a
U.S. Holder will recognize gain or loss equal to the difference between the
amount realized (if any) upon such termination and such U.S. Holder's adjusted
tax basis (if any) in the Purchase Contract at the time of such termination.
Payments of Contract Adjustment Payments or Deferred Contract Adjustment
Payments, if any, received by a U.S. Holder but not included in income by such
U.S. Holder should either reduce such U.S. Holder's tax basis in the Purchase
Contract or result in an amount realized on the termination of the Purchase
Contract. Any Contract Adjustment Payments or Deferred Contract Adjustment
Payments included in a U.S. Holder's income but not paid should increase such
U.S. Holder's tax basis in the Purchase Contract (see "--Income from Contract
Adjustment Payments and Deferred Contract Adjustment Payments" above). Any such
gain or loss may be long-term capital gain or loss depending upon the holding
period of the Purchase Contract. Capital gains of individuals are eligible for
reduced rates of taxation depending upon the holding period of such capital
assets. The deductibility of capital losses is subject to limitations. A U.S.
Holder will not recognize gain or loss on the receipt of such U.S. Holder's
proportionate share of the Trust Preferred Securities, Treasury Securities or
Treasury Portfolio upon termination of the Purchase Contract and will have the
same tax basis in such Trust Preferred Securities, Treasury Securities or
Treasury Portfolio as before such distribution.

     Adjustment to Settlement Rate.  U.S. Holders of FELINE PRIDES might be
treated as receiving a constructive distribution from the Company if (i) the
Settlement Rate is adjusted and as a result of such adjustment the proportionate
interest of U.S. Holders of FELINE PRIDES in the assets, earnings and profits of
the Company is increased and (ii) the adjustment is not made pursuant to a bona
fide, reasonable anti-dilution formula. An adjustment in the Settlement Rate
would not be considered made pursuant to such a formula if the adjustment were
made to compensate a U.S. Holder for certain taxable distributions with respect
to the Common Stock. Thus, under certain circumstances, an increase in the
Settlement Rate might give rise to a taxable dividend to U.S. Holders of FELINE
PRIDES even though such U.S. Holders would not receive any cash related thereto.
 
GROWTH PRIDES
 
     SUBSTITUTION OF TREASURY SECURITIES TO CREATE GROWTH PRIDES
 
     A U.S. holder of an Income PRIDES that delivers Treasury Securities to the
Collateral Agent in substitution for Trust Preferred Securities generally will
not recognize gain or loss upon the delivery of such Treasury Securities or the
release of the Trust Preferred Securities to such U.S. Holder. Such U.S. Holder
will continue to include in income any interest, OID or market discount or
amortize any bond premium otherwise includible or deductible, respectively, by
such U.S. Holder with respect to such Treasury Securities and Trust Preferred
Securities, and such U.S. Holder's tax basis in the Treasury Securities, the
Trust Preferred Securities and the Purchase Contract will not be affected by
such delivery and release. U.S. Holders should consult their tax advisors
concerning the tax consequences of purchasing, owning and disposing of Treasury
Securities.
 
     OWNERSHIP OF TREASURY SECURITIES
 
     A U.S. Holder will be treated as owning the Treasury Securities
constituting a part of the Growth PRIDES. The Company and, by acquiring FELINE
PRIDES, each U.S. Holder agree to treat such U.S. Holder as the owner, for
United States federal, state and local income and franchise tax purposes, of the
Treasury Securities constituting a part of the Growth PRIDES beneficially owned
by such U.S. Holder. The remainder of this summary will assume that U.S. Holders
of Growth PRIDES will be treated as the owners of the Treasury Securities
constituting a part of such Growth PRIDES for United States federal income tax
purposes.
 
     SUBSTITUTION OF TRUST PREFERRED SECURITIES TO RECREATE INCOME PRIDES
 
     A U.S. Holder of a Growth PRIDES that delivers Trust Preferred Securities
to the Collateral Agent to recreate an Income PRIDES generally will not
recognize gain or loss upon the delivery of such Trust Preferred Securities or
the release of the Treasury Securities to the U.S. Holder. Such U.S. Holder will
continue to include in income any interest, OID or market discount or amortize
any bond premium otherwise includible or deductible, respectively, by such U.S.
Holder with respect to such Treasury Securities and Trust Preferred Securities,
and such U.S. Holder's tax basis in the Treasury Securities, the Trust Preferred
Securities and the Purchase Contract will not be affected by such delivery and
release.
 
SALE OR DISPOSITION OF FELINE PRIDES
 
     Upon a disposition of FELINE PRIDES, a U.S. Holder will be treated as
having sold, exchanged or disposed of the Purchase Contract and the Trust
Preferred Securities, Treasury Portfolio or in the case of Growth PRIDES, the
Treasury Securities, that constitute such FELINE PRIDES and generally will have
gain or loss equal to the difference between the portion of the proceeds to such
U.S. Holder allocable to the Purchase Contract and the Trust Preferred
Securities, Treasury Portfolio or Treasury Securities, as the case may be, and
such U.S. Holder's respective adjusted tax bases in the Purchase Contract and
the Trust Preferred Securities, Treasury Portfolio or Treasury Securities. Such
gain or loss generally will be capital gain or loss, except to the extent that
such U.S. Holder is treated as having received an amount with respect to accrued
interest on the Trust Preferred Securities, which will be treated as ordinary
interest income, or to the extent such U.S. Holder is treated as having received
an amount with respect to accrued Contract Adjustment Payments or Deferred
Contract Adjustment Payments, which may be treated as ordinary income, in each
case to the extent not previously included in income. Such capital gain or loss
may be long-term capital gain or loss depending on the holding period of the
FELINE
 
                                      S-100
<PAGE>   145
 
PRIDES. Capital gains of individuals are eligible for reduced rates of taxation
depending upon the holding period of such capital assets. The deductibility of
capital losses is subject to limitations. If the disposition of FELINE PRIDES
occurs when the Purchase Contract has negative value, the U.S. Holder should be
considered to have received additional consideration for the Trust Preferred
Securities, Treasury Portfolio or Treasury Securities in an amount equal to such
negative value, and to have paid such amount to be released from the U.S.
Holder's obligation under the Purchase Contract. U.S. Holders should consult
their tax advisors regarding a disposition of the FELINE PRIDES at a time when
the Purchase Contract has negative value.
 
     Payments to a U.S. Holder of Contract Adjustment Payments or Deferred
Contract Adjustment Payments that have not previously been included in the
income of such U.S. Holder should either reduce such U.S. Holder's tax basis in
the Purchase Contract or result in an increase in the amount realized on the
disposition of the Purchase Contract. Any Contract Adjustment Payments or
Deferred Contract Adjustment Payments included in a U.S. Holder's income but not
paid should increase such U.S. Holder's tax basis in the Purchase Contract (see
"--Income from Contract Adjustment Payments and Deferred Contract Adjustment
Payments" above).
 
TAX EVENT REDEMPTION
 
     A Tax Event Redemption will be a taxable event for U.S. Holders of Trust
Preferred Securities. Gain or loss will be recognized by a U.S. Holder in an
amount equal to the difference between the Redemption price (whether paid
directly to such U.S. Holder or applied by the Collateral Agent to the purchase
of the Treasury Portfolio on behalf of holders of Income PRIDES), except to the
extent of amounts paid in respect of accrued but unpaid interest not previously
included income, and the U.S. Holder's adjusted tax basis in the Trust Preferred
Securities. Gain or loss realized by a U.S. Holder upon a Tax Event Redemption
will be capital gain or loss and may be long-term capital gain or loss depending
upon the holding period of the Trust Preferred Security. Capital gains of
individuals are eligible for reduced rates of taxation depending upon the
holding period of such capital assets. The deductibility of capital losses is
subject to limitations.
 
     Ownership of Treasury Portfolio.  The Company, the Trust, and by acquiring
Income PRIDES, each U.S. Holder agree to treat such U.S. Holder as the owner,
for United States federal, state and local income and franchise tax purposes, of
that portion of the Treasury Portfolio constituting a part of the Income PRIDES
beneficially owned by such U.S. Holder. Each U.S. Holder will include in income
any amount earned on such pro rata portion of the Treasury Portfolio for all
United States federal, state and local income and franchise tax purposes. Based
on such agreement, the remainder of this summary assumes that U.S. Holders of
Income PRIDES will be treated as the owners of the Treasury Portfolio
constituting a part of such Income PRIDES for United States federal, state and
local income and franchise tax purposes.
 
     Interest Income and Original Issue Discount.  The Treasury Portfolio will
consist of stripped U.S. Treasury Securities. A U.S. Holder of Income PRIDES
will be required to treat its pro rata portion of each U.S. Treasury Security in
the Treasury Portfolio as a bond that was originally issued on the date the
Collateral Agent acquired the relevant U.S. Treasury securities and will include
OID in income over the life of the U.S. Treasury Securities in an amount equal
to the U.S. Holder's pro rata portion of the excess of the amounts payable on
such U.S. Treasury securities over the value of the U.S. Treasury Securities at
the time the Collateral Agent acquires them on behalf of holders of Income
PRIDES. The amount of such excess will constitute only a portion of the total
amounts payable in respect of the Treasury Portfolio. Consequently, a
substantial portion of each scheduled interest payment to U.S. Holders will be
treated as a tax-free return of the U.S. Holder's investment in the Treasury
Portfolio and will not be considered current income for federal income tax
purposes.
 
     A U.S. Holder, whether on the cash or accrual method of tax accounting,
will be required to include OID (other than OID on short-term U.S. Treasury
Securities as defined below) in income for federal income tax purposes as it
accrues on a constant yield to maturity basis. See "Certain Federal Income Tax
Consequences-- Income PRIDES--Trust Preferred Securities--Interest Income and
Original Issue Discount" above. In the case of any U.S. Treasury Security with a
maturity of one year or less from the date it is purchased (a "short-term U.S.
Treasury Security"), only accrual basis taxpayers will be required to include
OID in income as it is accrued. Unless such an accrual basis U.S. Holder elects
to accrue the OID on a short-term U.S. Treasury Security according to the
constant-yield-to-maturity method, such OID will be accrued on a straight-line
basis.
 
                                      S-101
<PAGE>   146
 
     Tax Basis of the Treasury Portfolio.  A U.S. Holder's initial tax basis in
the Treasury Portfolio will equal such U.S. Holder's pro rata portion of the
amount paid by the Collateral Agent for the Treasury Portfolio. A U.S. Holder's
tax basis in the Treasury Portfolio will be increased by the amount of OID
included in income with respect thereto and decreased by the amount of cash
received in respect thereof.
 
BACKUP WITHHOLDING TAX AND INFORMATION REPORTING
 
     Payments under the FELINE PRIDES, Trust Preferred Securities or Common
Stock acquired under a Purchase Contract, the proceeds received with respect to
a fractional share of Common Stock upon the settlement of a Purchase Contract,
and the sale of FELINE PRIDES, Trust Preferred Securities or Common Stock
acquired under a Purchase Contract, may be subject to information reporting and
United States federal backup withholding tax at the rate of 31% if the U.S.
Holder thereof fails to supply an accurate taxpayer identification number or
otherwise fails to comply with applicable United States information reporting or
certification requirements. Any amounts so withheld will be allowed as a credit
against such U.S. Holder's United States federal income tax liability.

                          DESCRIPTION OF COMMON STOCK
 
     The following brief description of the Company's capital stock does not
purport to be complete and is subject in all respects to applicable Pennsylvania
law and to the provisions of the Restated Articles and its Restated By-Laws,
copies of which have been filed with the Commission.
 
COMMON STOCK
 
     The Company has authorized 70,000,000 shares of Capital Stock, par value
$1.25 per share ("Common Stock"). As of October 31, 1997, there were 26,264,454
shares of Common Stock outstanding. Holders of Common Stock are entitled to such
dividends as may be declared by the Board of Directors out of funds legally
available therefor after payment of dividends on any outstanding Preferred Stock
and are entitled to one vote for each share of Common Stock held by them with
respect to all matters upon which they are entitled to vote.
 
PREFERRED STOCK
 
     The Company has authorized 5,000,000 shares of Class A Preferred Stock, no
par value per share (the "Preferred Stock"). At present there are no shares of
Preferred Stock outstanding. The Board of Directors of the Company, without
further action by the stockholders, is authorized to designate and issue in
series Preferred Stock and to fix as to any series the dividend rate, redemption
prices, preferences on dissolution, the terms of any sinking fund, conversion
rights, voting rights, and any other preferences or special rights and
qualifications. The Board of Directors of the Company has authorized 200,000
shares of Series One Preferred Stock for use in the Rights Plan. See "Rights
Plan".
 
     Any Preferred Stock so issued may rank senior to the Common Stock with
respect to the payment of dividends or amounts upon liquidation, dissolution or
winding up, or both. In addition, any such shares of Preferred Stock may have
class or series voting rights. Issuances of Preferred Stock, while providing the
Company with flexibility in connection with general corporate purposes, may,
among other things, have an adverse effect on the rights of holders of Common
Stock. The Company has no present plans to issue any Preferred Stock.
 
COVENANT RESTRICTIONS
 
     The Company's New Bank Credit Facility contains financial and operating
covenants, including restrictions on the ability of the Company to, among other
things, incur additional debt, make advances and investments, create, incur or
permit the existence of certain liens, make loans or guarantees and requires the
Company to achieve and maintain certain financial ratios, including minimum net
worth, maximum leverage ratio and minimum fixed charge coverage ratio.
 
     The terms of the indenture under which the Company will issue
$     ,000,000 of      % debentures which mature on           , 200 in
connection with the FELINE PRIDES Offering, prohibits the Company from declaring
or paying any dividends on or making any distributions with respect to its
Common Stock unless the Company has made at that time all quarterly payments of
interest on the debentures. See "Description of FELINE PRIDES Offering."
 
CERTAIN CHARTER AND BY-LAW PROVISIONS
 
     Certain provisions of the Restated Articles and Restated By-Laws could have
an anti-takeover effect. These provisions are intended to enhance the likelihood
of continuity and stability in the composition of the Company's Board of
Directors and in the policies formulated by the Board and to discourage an
unsolicited takeover of the Company if the Board determines that such takeover
is not in the best interests of the Company and its shareholders. However, these
provisions could have the effect of discouraging certain attempts to acquire the
Company or remove incumbent management even if some or a majority of
shareholders deemed such an attempt to be in their best interests.
 
     The provisions in the Restated Articles and Restated By-Laws include: (i)
the classification of the Board of Directors into three classes; (ii) a
procedure which requires shareholders to nominate directors in advance of a
 
                                      S-103
<PAGE>   148
 
meeting to elect such directors; and (iii) the authority to issue additional
shares of Common Stock or Preferred Stock without shareholder approval.
 
     The Restated Articles also include a provision requiring a 75 percent
shareholder vote for certain mergers or other business combinations or
transactions with five percent shareholders; a provision requiring a 75 percent
shareholder vote to remove the entire Board, a class of the Board, any
individual member of the Board without cause, or to increase the size of the
Board to more than twelve members or decrease the size of the Board to fewer
than eight members; a provision requiring disinterested shareholder approval of
stock repurchases at a premium over market by the Company from certain four
percent Shareholders (as defined in the Restated Articles); and a provision
requiring a majority of disinterested shareholders to approve certain business
combinations involving a stockholder who beneficially owns more than 10 percent
of the voting power of the Company, unless certain minimum price, form of
consideration and procedural requirements are satisfied or the transaction is
approved by a majority of disinterested directors.
 
     Pursuant to the Restated Articles, the Board of Directors is permitted to
consider the effects of a change in control on non-shareholder constituencies of
the Company, such as its employees, suppliers, creditors, customers and the
communities in which it operates. Pursuant to this provision, the Board may be
guided by factors in addition to price and other financial considerations.
 
     PBCL Anti-Takeover Provisions.  The Pennsylvania Business Corporation Law
(the "PBCL") contains a number of statutory "anti-takeover" provisions,
including Subchapters E, F, G and H of Chapter 25 and Section 2538 of the PBCL,
which apply automatically to a Pennsylvania registered corporation (usually a
public company) unless such corporation elects to opt-out as provided in such
provisions. The Company, as a Pennsylvania registered corporation, has elected
in its Restated Articles to opt-out of certain of the anti-takeover provisions
entirely, namely Subchapters G and H.
 
     The following descriptions are qualified in their entirety by reference to
such provisions of the PBCL:
 
          Subchapter E (relating to control transactions) generally provides
     that if any person or group acquires 20% or more of the voting power of a
     covered corporation, the remaining shareholders may demand from such person
     or group the fair value of their shares, including a proportionate amount
     of any control premium.
 
          Subchapter F (relating to business combinations) generally delays for
     five years and imposes conditions upon "business combinations" between an
     "interested shareholder" and the corporation. The term "business
     combination" is defined broadly to include various transactions between a
     corporation and an interested shareholder including mergers, sales or
     leases of specified amounts of assets, liquidations, reclassifications and
     issuances of specified amounts of additional shares of stock of the
     corporation. An "interested shareholder" is defined generally as the
     beneficial owner of at least 20% of a corporation's voting shares.
 
          Section 2538 of the PBCL generally establishes certain shareholder
     approval requirements with respect to specified transactions with
     "interested shareholders."
 
TRANSFER AGENT AND REGISTRAR
 
     ChaseMellon Shareholder Services, L.L.C. is the Transfer Agent and
Registrar for the Common Stock.
 
RIGHTS AGREEMENT
 
     The Company has adopted a rights plan pursuant to which the Board of
Directors authorized and the Company distributed one preferred stock purchase
right (each a "right") for each outstanding share of Common Stock of the
Company. The terms of the rights are governed by a Rights Agreement between the
Company and Mellon Bank, N.A., as Rights Agent, dated as of October 25, 1990
(the "Rights Agreement"). The rights, which currently are automatically
transferred with the related shares of Common Stock and are not separately
transferable, will entitle the holder thereof to purchase one-hundredth of a
share of a new series of preferred stock of the Company at a price of $105
(subject to certain adjustments).
 
                                      S-104
<PAGE>   149
 
     Subject to certain restrictions, the rights become exercisable only if a
person or group of persons acquires or intends to make a tender offer for 20
percent or more of the Company's Common Stock. If any person acquires 20 percent
of the Common Stock, each right will entitle the shareholder to receive upon
exercise that number of shares of Common Stock having a market value of two
times the exercise price. If the Company is acquired in a merger or certain
other business combinations, each right then will entitle the shareholder to
purchase at the exercise price, that number of shares of the acquiring company
having a market value of two times the exercise price.
 
     The rights will expire on November 2, 2000, and are subject to redemption
in certain circumstances by the Company at a redemption price of $0.01 per
right.
 
     The foregoing summary description of the Rights Agreement does not purport
to be complete and is qualified in its entirety by reference to the Rights
Agreement, a copy of which has been filed with the Commission as an exhibit in
the Registration Statement of which this Prospectus Supplement forms a part. For
a more detailed description of the Rights Agreement, see the Company's Form 8-A
filed with the Commission with respect to the rights incorporated by reference
into this Prospectus Supplement.

     In the Purchase Agreement, the several Underwriters have agreed, subject to
the terms and conditions set forth therein, to purchase all of the Income PRIDES
being sold hereby if any of the Income PRIDES are purchased. Under certain
circumstances, under the Purchase Agreement, the commitments of non-defaulting
Underwriters may be increased.
 
     The Representatives have advised the Company and the Trust that the
Underwriters propose initially to offer the Income PRIDES offered hereby to the
public at the public offering price set forth on the cover page of this
Prospectus Supplement, and to certain dealers at such price less a concession
not in excess of $     per Income PRIDES. The Underwriters may allow, and such
dealers may reallow, a discount not in excess of $          per Income PRIDES on
sales to certain other dealers. After the public offering, the public offering
price, concession and discount may be changed.
 
     The Company and the Trust have granted an option to the Underwriters,
exercisable for 30 days after the date of this Prospectus Supplement, to
purchase up to an aggregate of           additional Income PRIDES at the public
offering price set forth on the cover page of this Prospectus Supplement, less
the underwriting discount. The Underwriters may exercise this option only to
cover over-allotments, if any, made on the sale of the Income PRIDES offered
hereby. To the extent that the Underwriters exercise this option, each
Underwriter will be obligated, subject to certain conditions, to purchase a
number of additional Income PRIDES proportionate to such Underwriter's initial
amount reflected in the foregoing table.
 
     The Company and the Trust have agreed not to (i) directly or indirectly,
offer, pledge, sell, contract to sell, sell any option or contract to purchase,
purchase any option or contract to sell, grant any option, right or warrant to
purchase or otherwise transfer or dispose of any Income PRIDES, Trust Preferred
Securities, Purchase Contracts or Common Stock, as the case may be, or any
securities of the Company or the Trust similar to the Income PRIDES, Trust
Preferred Securities, Purchase Contracts or Common Stock or any Security
convertible into or exercisable or exchangeable for Income PRIDES, Trust
Preferred Securities, Purchase Contracts or Common Stock or file any
registration statement under the Securities Act with respect to any of the
foregoing or (ii) enter into any swap or any other agreement or any transaction
that transfers, in whole or in part, directly or indirectly, the economic
consequence of ownership of the Income PRIDES, Trust Preferred Securities,
Purchase Contracts or Common Stock or any securities convertible into or
exercisable or exchangeable for Income PRIDES, Trust Preferred Securities,
Purchase Contracts or Common Stock whether any such swap or transaction
described in clause (i) or (ii) above is to be settled by delivery of Income
PRIDES, Trust Preferred Securities, Purchase Contracts or Common Stock or such
other securities, in cash or otherwise, for a period of 90 days from the date of
this Prospectus Supplement without the prior written consent of Merrill Lynch,
other than (i) pursuant to the Purchase Agreement, (ii) Growth PRIDES or Income
PRIDES to be created or recreated upon substitution of pledged securities or
shares of Common Stock issuable upon early settlement of the Income PRIDES or
Growth PRIDES, (iii) any shares of Common Stock issued by the Company upon
exercise of an option, warrant, or the conversion of a security described
herein, (iv) any shares of Common Stock issued, or options to purchase
 
                                      S-106
<PAGE>   151
 
such shares granted, pursuant to existing employee benefit plans described
herein or (v) any shares of Common Stock issued pursuant to any non-employee
director stock plan or dividend reinvestment plan.
 
     The Company and the Trust have agreed to indemnify the Underwriters against
certain liabilities, including liabilities under the Securities Act of 1933, as
amended, or to contribute to payments the Underwriters may be required to make
in respect hereof.
 
     Until the distribution of the Income PRIDES is completed, rules of the
Securities and Exchange Commission may limit the ability of the Underwriters and
certain selling group members to bid for and purchase the Securities or the
Common Stock. As an exception to these rules, the Representatives are permitted
to engage in certain transactions that stabilize the price of the Securities or
the Common Stock. Such transactions consist of bids or purchases for the purpose
of pegging, fixing or maintaining the price of the Securities or the Common
Stock.
 
     If the Underwriters create a short position in the Securities in connection
with the Offering, i.e., if they sell more Securities than are set forth on the
cover page of this Prospectus Supplement, the Representatives may reduce that
short position by purchasing Securities in the open market. The Representatives
may also elect to reduce any short position by exercising all or part of the
over-allotment option described above.
 
     The Representatives may also impose a penalty bid on certain Underwriters
and selling group members. This means that if the Representatives purchase
Securities in the open market to reduce the Underwriters' short position or to
stabilize the price of the Securities, they may reclaim the amount of the
selling concession from the Underwriters and selling group members who sold
those shares as part of the Offering.
 
     In general, purchases of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher than
it might be in the absence of such purchases. The imposition of a penalty bid
might also have an effect on the price of the Securities to the extent that it
discourages resales of the Securities.
 
     Neither the Company, the Trust nor any of the Underwriters makes any
representation or prediction as to the direction or magnitude of any effect that
the transactions described above may have on the price of the Securities or the
Common Stock. In addition, neither the Company, the Trust nor any of the
Underwriters makes any representation that the Representatives will engage in
such transactions or that such transactions, once commenced, will not be
discontinued without notice.
 
     Prior to the Offering, there has been no established trading market for the
Income PRIDES. In determining the terms of the Income PRIDES, including the
public offering price, the Company, the Trust and the Underwriters considered
the market price of the Common Stock and also considered the Company's recent
results of operations, the future prospects of the Company and the industry in
general, market prices and terms of, and yields on, securities of other
companies considered to be comparable to the Company and prevailing conditions
in the securities markets. Application has been made to list the Income PRIDES
on the NYSE under the trading symbol "       ." The Company and the Trust have
been advised by the Underwriters that they presently intend to make a market for
the Growth PRIDES and the Trust Preferred Securities; however, they are not
obligated to do so and any market making may be discontinued at any time. There
can be no assurance that an active trading market will develop for the Income
PRIDES, Growth PRIDES or Trust Preferred Securities or that the Income PRIDES
initially will trade in the public market subsequent to the Offering at or above
the initial public offering price.
 
     This Prospectus Supplement, as amended or supplemented, may be used by the
Remarketing Agent for remarketing the Trust Preferred Securities at such time as
is necessary.
 
     Merrill Lynch has from time to time provided investment banking advisory
services to the Company, for which it has received customary compensation, and
may continue to do so in the future. Merrill Lynch has acted as financial
advisor to the Company in connection with the Merger, including serving as
dealer manager with respect to the Tender Offer. In this regard, the Company has
agreed to indemnify Merrill Lynch against certain liabilities. CIBC Oppenheimer
Corp., Goldman, Sachs & Co. and Lehman Brothers Inc. have from time to time
provided investment banking or financial advisory services to the Company, and
may continue to do so in the future.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Shareholders of Kennametal Inc.
 
We have audited the accompanying consolidated balance sheets of Kennametal Inc.
and subsidiaries as of June 30, 1996 and 1997, and the related consolidated
statements of income, shareholders' equity and cash flows for each of the three
years in the period ended June 30, 1997. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Kennametal Inc. and
subsidiaries as of June 30, 1996 and 1997, and the results of their operations
and their cash flows for each of the three years in the period ended June 30,
1997, in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1. NATURE OF OPERATIONS
 
     The Company is a global enterprise engaged in the manufacture, purchase and
distribution of a broad range of tools, tooling systems, supplies and services
for the metalworking, mining and highway construction industries.
 
NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     The summary of significant accounting policies is presented below to assist
in evaluating the Company's consolidated financial statements.
 
     PRINCIPLES OF CONSOLIDATION. The consolidated financial statements include
the accounts of the Company and its majority-owned subsidiaries. All significant
intercompany balances and transactions have been eliminated.
 
     USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS. The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
     CASH EQUIVALENTS. Temporary cash investments having original maturities of
three months or less are considered cash equivalents. Cash equivalents consist
principally of investments in money market funds and certificates of deposit.
 
     ACCOUNTS RECEIVABLE included $16.6 million and $12.8 million of receivables
from affiliates at June 30, 1996 and 1997, respectively.
 
     INVENTORIES are carried at the lower of cost or market. The Company uses
the last-in, first-out (LIFO) method for determining the cost of a significant
portion of its U.S. inventories. The remainder of inventories is determined
under the first-in, first-out (FIFO) or average cost methods.
 
     PROPERTY, PLANT AND EQUIPMENT are carried at cost. Major improvements are
capitalized, while maintenance and repairs are generally expensed as incurred.
Retirements and disposals are removed from cost and accumulated depreciation
accounts, with the gain or loss reflected in income. Interest is capitalized
during the construction of major facilities. Capitalized interest is included in
the cost of the constructed asset and is amortized over its estimated useful
life.
 
     Depreciation for financial reporting purposes is computed using the
straight-line method over the estimated useful lives of the assets ranging from
3 to 40 years. Leased property and equipment under capital leases are amortized
using the straight-line method over the terms of the related leases.
 
     INTANGIBLE ASSETS, which include the excess of cost over net assets of
acquired companies, are amortized using the straight-line method over periods
ranging from 3 to 40 years. The Company assesses the recoverability of goodwill
by determining whether the amortization of the goodwill balance over its
remaining life can be recovered through undiscounted future operating cash flows
of the acquired entities.
 
     RESEARCH AND DEVELOPMENT COSTS are expensed as incurred.
 
     INCOME TAXES. Deferred income taxes are recognized based on the future
income tax effects (using enacted tax laws and rates) of differences in the
carrying amounts of assets and liabilities for financial reporting and tax
purposes. A valuation allowance is recognized if it is "more likely than not"
that some or all of a deferred tax asset will not be realized.
 
     FOREIGN CURRENCY TRANSLATION. For the most part, assets and liabilities of
international operations are translated into U.S. dollars using year-end
exchange rates, while revenues and expenses are translated at average
 
                                       F-7

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
 
exchange rates throughout the year. The resulting net translation adjustments
are recorded as a separate component of shareholders' equity.
 
     PENSION PLANS cover substantially all employees. Pension benefits are based
on years of service and, for certain plans, on average compensation immediately
preceding retirement. Pension costs are determined in accordance with Statement
of Financial Accounting Standards (SFAS) No. 87, "Employers' Accounting for
Pensions." The Company funds pension costs in accordance with the funding
requirements of the Employee Retirement Income Security Act of 1974 (ERISA) for
U.S. plans and in accordance with local regulations or customs for non-U.S.
plans.
 
     EARNINGS PER SHARE is computed using the weighted average number of shares
outstanding during the year.
 
     REVENUE RECOGNITION. The Company recognizes revenue from product sales upon
transfer of title to the customer.
 
     NEW ACCOUNTING STANDARDS. Effective July 1, 1996, the Company adopted SFAS
No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed of." The adoption of SFAS No. 121 did not have an impact
on the consolidated financial statements, as the statement is consistent with
existing Company policy.
 
     Additionally on July 1, 1996, the Company adopted SFAS No. 123, "Accounting
for Stock-Based Compensation." Under the provisions of SFAS No. 123, companies
may elect to account for stock-based compensation plans using a fair-value-based
method or may continue measuring compensation expense for those plans using the
intrinsic-value-based method. The Company will continue to use the
intrinsic-value-based method, which does not result in compensation cost. The
Company's stock compensation plans are discussed in Note 13.
 
     The Financial Accounting Standards Board recently issued SFAS No. 128,
"Earnings Per Share" and SFAS No. 129, "Disclosure of Information about Capital
Structures." SFAS No. 128 was issued in February 1997 and is effective for
periods ending after December 15, 1997. This statement, upon adoption, will
require all prior period earnings per share (EPS) data to be restated to conform
to the provisions of the statement. This statement's objective is to simplify
the computations of EPS and to make the U.S. standard for EPS computations more
compatible with that of the International Accounting Standards Committee. The
Company will adopt SFAS No. 128 in fiscal 1998 and does not anticipate that the
statement will have a significant impact on its reported EPS.
 
     SFAS No. 129 was issued in February 1997 and is effective for periods
ending after December 15, 1997. This statement, upon adoption, will require all
companies to provide specific disclosure regarding their capital structure. SFAS
No. 129 will specify the disclosure for all companies, including descriptions of
their capital structure and the contractual rights of the holders of such
securities. The Company will adopt SFAS No. 129 in fiscal 1998 and does not
anticipate that the statement will have a significant impact on its disclosures.
 
     Additionally, in June 1997, the FASB issued SFAS No. 130, "Reporting
Comprehensive Income" (SFAS No. 130) and SFAS No. 131, "Disclosures About
Segments of an Enterprise and Related Information" (SFAS No. 131). SFAS No. 130
is effective for years ending after December 15, 1997. SFAS No. 130 establishes
standards for reporting and display of comprehensive income and its components
in a full set of general-purpose financial statements. The Company will adopt
SFAS No. 130 in fiscal 1998 and does not anticipate that the statement will have
a significant impact on its disclosures.
 
     SFAS No. 131 introduces a new model for segment reporting called the
"management approach." The management approach is based on the way the chief
operating decision-maker organizes segments within a company for making
operating decisions and assessing performance. SFAS No. 131 is effective for
fiscal years beginning after December 15, 1997. The Company is in the process of
evaluating the effect of applying this statement.

     RECLASSIFICATIONS. Certain amounts in the prior years' consolidated
financial statements have been reclassified to conform with the current year
presentation.
 
     INTERIM UNAUDITED FINANCIAL INFORMATION. The consolidated financial
statements as of, and for the three months ended September 30, 1996 and 1997 are
unaudited; however, in the opinion of management all adjustments (consisting
solely of normal recurring adjustments) necessary for a fair presentation have
been made. The results of interim periods are not necessarily indicative of the
results to be expected for the full fiscal year.
 
NOTE 3. ISSUANCE OF SUBSIDIARY STOCK
 
     On July 2, 1997, an initial public offering (IPO) of approximately 4.9
million shares of common stock at a price of $20 per share of JLK Direct
Distribution Inc. (JLK), a newly formed subsidiary of the Company, was
consummated. JLK operates the industrial supply operations consisting of the
Company's wholly owned J&L Industrial Supply (J&L) subsidiary and its Full
Service Supply programs. The net proceeds from the offering were approximately
$90 million and represented approximately 20 percent of JLK's common stock. The
transaction was accounted for as an equity transaction in the consolidated
financial statements. The net proceeds were used by JLK to repay $20 million of
indebtedness related to a dividend to the Company and $20 million related to
intercompany obligations to the Company. The Company used these proceeds to
repay short-term debt. In connection with the IPO, the remaining net proceeds
were loaned to the Company, under an intercompany debt/investment and cash
management agreement at a fluctuating rate of interest equal to the Company's
short-term borrowing costs. The Company will maintain unused lines of credit to
enable it to repay any portion of the borrowed funds as the amounts are due on
demand by JLK.
 
     The Company owns approximately 80 percent of the outstanding common stock
of JLK and intends to retain a majority of both the economic and voting
interests of JLK.

</TABLE>
 
     Inventories are stated at the lower of cost or market. Cost is determined
using the last-in, first-out (LIFO) method for a significant portion of U.S.
inventories and the first-in, first-out (FIFO) method or average cost for other
inventories. The Company used the LIFO method of valuing its inventories for
approximately 55 and 56 percent of total inventories at June 30, 1996 and 1997,
respectively, and for approximately 45 percent of total inventories at September
30, 1997. The Company uses the LIFO method for valuing the majority of its
inventories in order to more closely match current costs with current revenues,
thereby reducing the effects of inflation on earnings.

NOTE 7. NOTES PAYABLE AND LINES OF CREDIT
 
     Notes payable to banks of $57.5 million and $120.2 million at June 30, 1996
and 1997, respectively, represent short-term borrowings under U.S. and
international credit lines with commercial banks. These credit lines totaled
approximately $280 million at June 30, 1997, of which $160 million was unused.
The weighted average interest rate for short-term borrowings was 5.6 percent and
6.3 percent at June 30, 1996 and 1997, respectively.
 
     The Company has available U.S. credit lines totaling $175 million that are
covered by a revolving credit agreement that amounts to $150 million and another
agreement totaling $25 million. The revolving credit agreement allows the
Company to borrow up to $150 million at fixed or variable interest rates. This
credit line expires during fiscal 2001 and requires the Company to pay a
facility fee on the total line. The Company has the option to terminate this
agreement in whole or in part at any time.
 
     During 1997, the Company's J&L subsidiary obtained a $25 million line of
credit with a bank and borrowed $20 million under the line of credit to fund a
dividend to the Company. Interest payable under the line of credit was based on
LIBOR plus 25 basis points. The Company guaranteed repayment of the line of
credit in the event of default by J&L. The line of credit was repaid and
canceled in full during July 1997.

     Included in deferred tax assets at June 30, 1997, are unrealized tax
benefits totaling $27.2 million related to net operating loss carryforwards. The
realization of these tax benefits is contingent on future taxable income in
certain international operations. Of this amount, approximately $23.6 million
relates to net operating loss carryforwards in Germany, which can be carried
forward indefinitely. The Company's operations in Germany are profitable.
 
     The remaining unrealized tax benefits relate to net operating loss
carryforwards in certain other international operations, which expire at various
dates through 2002. The Company established a valuation allowance of $3.6
million to offset the deferred tax benefits that may not be realized before the
expiration of the carryforward periods.

NOTE 10. OTHER POSTRETIREMENT AND POSTEMPLOYMENT BENEFITS
 
     The Company presently provides varying levels of postretirement health care
and life insurance benefits to most U.S. employees. Postretirement health care
benefits are available to employees and their spouses retiring at or after age
65 with five or more years of service after age 40. Employees (and their
spouses) retiring under age 65 before January 1, 1998, with 20 or more years of
service after age 40 also are eligible to receive postretirement health care
benefits. Beginning with retirements on or after January 1, 1998, Kennametal's
portion of the costs of postretirement health care benefits will be capped at
1996 levels.
 
     The components of other postretirement benefit costs for the Company's U.S.
plans were as follows:

     A 1 percent increase in the health care cost trend rate would have
increased other postretirement benefit costs by $0.1 million in 1997 and the
accumulated benefit obligation by $1.0 million at June 30, 1997.
 
     The Company provides for postemployment benefits pursuant to SFAS No. 112,
"Employers' Accounting for Postemployment Benefits." The Company accrues the
cost of separation and other benefits provided to former or inactive employees
after employment but before retirement. Postemployment benefit costs were not
significant in 1995, 1996 and 1997, respectively.
 
NOTE 11. RESTRUCTURING CHARGE
 
     On April 29, 1996, the Board of Directors approved the Company's plan (the
Plan) to relocate its North America Metalworking Headquarters from Raleigh,
North Carolina, to Latrobe, Pennsylvania. In connection with the Plan, the
Company is constructing a new world headquarters at an estimated cost of $20
million. The relocation was made to globalize key functions and to provide a
more efficient corporate structure. The action affected approximately 300
employees in Raleigh, North Carolina, all of whom were offered the opportunity
to move to Latrobe, Pennsylvania. As a result, a pretax charge of $2.0 million
was recorded in the fourth quarter of fiscal 1996. The charge was taken to cover
the one-time costs of employee separation arrangements and early retirement
costs.
 
     The costs resulting from the relocation of employees, hiring and training
new employees, and other costs resulting from the temporary duplication of
certain operations were not included in the one-time charge and will be included
in operating expenses as incurred. The costs related to these items were
estimated to be approximately $9.0 million pretax, $4.7 million that was
recorded in fiscal 1997 and the remainder that will be incurred in fiscal 1998.
 
     During the fourth quarter of fiscal 1996, the Company also recorded a
one-time pretax charge of $0.7 million related to the closure of a manufacturing
facility in Canada. The supply of products produced at this location will be
continued from other Company locations. The restructuring was substantially
complete in 1997.
 
NOTE 12. FINANCIAL INSTRUMENTS
 
     FAIR VALUE.  The Company had $21.9 million in cash and equivalents at June
30, 1997, which approximates fair value because of the short maturity of these
investments.
 
     The estimated fair value of term debt was $44.9 million at June 30, 1997.
Fair value was determined using discounted cash flow analysis and the Company's
incremental borrowing rates for similar types of arrangements.
 
     OFF-BALANCE-SHEET RISK.  The Company uses forward foreign exchange
contracts in the normal course of business to hedge foreign currency exposures
of underlying receivables and payables. These financial instruments involve
credit risk in excess of the amount recognized in the financial statements. The
Company controls credit risk through credit evaluations, limits and monitoring
procedures. There were no financial instruments with significant
off-balance-sheet risk at June 30, 1997.

                                KENNAMETAL INC.
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
 
     CONCENTRATIONS OF CREDIT RISK.  Financial instruments that potentially
subject the Company to concentrations of credit risk consist primarily of
temporary cash investments and trade receivables. By policy, the Company makes
temporary cash investments with high credit quality financial institutions. With
respect to trade receivables, concentrations of credit risk are significantly
reduced because the Company serves numerous customers in many industries and
geographic areas. As of June 30, 1997, the Company had no significant
concentrations of credit risk.
 
NOTE 13. STOCK OPTIONS
 
     Under stock option plans approved by shareholders in 1996, 1992 and 1988,
stock options generally are granted to eligible employees at fair market value
at the date of grant. Options are exercisable under specified conditions for up
to 10 years from the date of grant. No options may be granted under the 1988
plan after October 1998, no options may be granted under the 1992 plan after
October 2002, and no options may be granted under the 1996 plan after October
2006. No charges to income have resulted from the operation of the plans.
 
     Under provisions of the plans, participants may deliver Kennametal stock in
payment of the option price and receive credit for the fair market value of the
shares on the date of delivery. Shares valued at $0.4 million (13,728 shares),
$0.9 million (22,740 shares) and $0.5 million (11,684 shares) were delivered in
1995, 1996 and 1997, respectively.
 
     Under the 1996, 1992 and 1988 plans, shares may be awarded to eligible
employees without payment. The respective plans specify such shares are awarded
in the name of the employee, who has all the rights of a shareholder, subject to
certain restrictions or forfeitures. Such awards were not significant in 1995,
1996 and 1997.
 
     The Company adopted the disclosure requirements of SFAS No. 123 effective
with the 1997 consolidated financial statements, but elected to continue to
measure compensation expense in accordance with Accounting Principles Board
Opinion No. 25, "Accounting for Stock Issued to Employees." Accordingly, no
compensation expense for stock options has been recognized in the accompanying
consolidated financial statements. If compensation expense had been determined
based on the estimated fair value of options granted in 1996 and 1997,
consistent with the methodology in SFAS No. 123, the effect on the Company's
1996 and 1997 net income and earnings per share would have been reduced to the
pro forma amounts indicated below:

NOTE 14. ENVIRONMENTAL MATTERS
 
     The Company has been involved in various environmental cleanup and
remediation activities at several of its manufacturing facilities. In addition,
the Company has been named as a potentially responsible party at several
Superfund sites in the United States. However, it is management's opinion, based
on its evaluations and discussions with outside counsel and independent
consultants, that the ultimate resolution of these environmental matters will
not have a material adverse effect on the results of operations, financial
position or cash flows of the Company.
 
     The Company maintains a Corporate Environmental, Health and Safety (EH&S)
Department as well as an EH&S Policy Committee to ensure compliance with
environmental regulations and to monitor and oversee remediation activities. In
addition, the Company has established an EH&S administrator at each of its
domestic manufacturing facilities. The Company's financial management team
periodically meets with members of the Corporate EH&S Department and the
Corporate Legal Department to review and evaluate the status of environmental
projects and contingencies. On a quarterly and annual basis, management
establishes or adjusts financial provisions and reserves for environmental
contingencies in accordance with SFAS No. 5, "Accounting for Contingencies."

NOTE 15. SHAREHOLDER RIGHTS PLAN
 
     Pursuant to the Company's Shareholder Rights Plan, one-half of a right is
associated with each share of capital stock. Each right entitles a shareholder
to buy 1/100th of a share of a new series of preferred stock at a price of $105
(subject to adjustment).
 
     The rights will be exercisable only if a person or group of persons
acquires or intends to make a tender offer for 20 percent or more of the
Company's capital stock. If any person acquires 20 percent of the capital stock,
each right will entitle the shareholder to receive that number of shares of
capital stock having a market value of two times the exercise price. If the
Company is acquired in a merger or other business combination, each right will
entitle the shareholder to purchase at the exercise price that number of shares
of the acquiring Company having a market value of two times the exercise price.
The rights will expire on November 2, 2000, and are subject to redemption by the
Company at $0.01 per right.
 
NOTE 16. ACQUISITIONS
 
     Fiscal 1997 results included sales of approximately $16 million from five
companies acquired during the year for a total consideration of approximately
$19 million. The acquisitions were accounted for using the purchase method of
accounting. The consolidated financial statements include the operating results
of each business from the date of acquisition. Pro forma results of operations
have not been presented because the effects of these acquisitions were not
significant.

     Intersegment transfers are accounted for at arm's-length prices, reflecting
prevailing market conditions within the various geographic areas. Such sales and
associated costs are eliminated in the consolidated financial statements.
 
     Identifiable assets are those assets that are identified with the
operations in each geographic area. Corporate assets consist mainly of cash and
cash equivalents, investments in affiliated companies and other assets.
 
     Sales to a single customer did not aggregate 10 percent or more of total

NOTE 18. SUBSEQUENT EVENTS
 
     The Company recently acquired Rubig G.m.b.H. of Munich, Germany, Presto
Engineers Cutting Tools Limited of Sheffield, United Kingdom, and Car-Max Tool &
Cutter Sales, Inc. The companies had aggregate annual sales of approximately $46
million in 1996. The acquisitions were accounted for using the purchase method
of accounting. The consolidated financial statements include the operating
results of each business from the date of acquisition. The Company has recently
entered into an agreement to acquire GRS Industrial Supply Company with annual
sales of approximately $20 million in 1996.
 
     On October 10, 1997, Kennametal and Kennametal Acquisition Corp.
(Acquisition Corp.) entered into the Merger Agreement with Greenfield pursuant
to which Acquisition Corp. purchased at $38 per share on November 17, 1997,
approximately 16,179,976 shares (98% of the outstanding) of Greenfield's common
stock. The Merger occurred on November 18, 1997, and Greenfield became a
wholly-owned subsidiary of Kennametal on that date. The total purchase price for
the acquisition of Greenfield (including estimated transaction costs and assumed
Greenfield debt and convertible redeemable preferred securities of approximately
$320 million) is estimated to be $1.0 billion.
 
     In connection with the acquisition of Greenfield, the Company, on November
17, 1997, entered into the New Bank Credit Facility. As of November 18, 1997,
the Company had borrowed $500 million in term loans and approximately $300
million in revolving credit loans under the New Bank Credit Facility. The
proceeds from these loans were principally used to pay for the shares of common
stock of Greenfield purchased in the Tender Offer and the Merger, to pay
transaction costs, to refinance certain indebtedness of Greenfield and to
refinance certain indebtedness of the Company. Subject to certain conditions,
the New Bank Credit Facility permits revolving credit loans of up to $900
million for working capital requirements, capital expenditures, and general
corporate purposes. The New Bank Credit Facility initially will be secured by
all of the stock of certain of Kennametal's significant domestic subsidiaries,
by guarantees of certain of such subsidiaries and by 65% of the stock of
Kennametal's significant foreign subsidiaries. The New Bank Credit Facility
contains various restrictive covenants and affirmative covenants requiring the
maintenance of certain financial ratios. The term loans under the New Bank
Credit Facility are subject to mandatory prepayments commencing on November 30,
1998, and all loans mature on August 31, 2002. Proceeds from the Common Stock
Offerings and the Feline PRIDES Offering will be used to prepay term loans under
the New Bank Credit Facility.

To the Board of Directors and Stockholders
of Greenfield Industries, Inc.
 
     In our opinion, the accompanying consolidated balance sheets and the
related consolidated statements of operations, of changes in stockholders'
equity and of cash flows present fairly, in all material respects, the financial
position of Greenfield Industries, Inc. and its subsidiaries at December 31,
1995 and 1996, and the results of their operations and their cash flows for each
of the three years in the period ended December 31, 1996, in conformity with
generally accepted accounting principles. These financial statements are the
responsibility of the Company's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with generally accepted auditing
standards which require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                 (DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)
 
1. BUSINESS
 
     Greenfield Industries, Inc. (Greenfield or the Company) is a global
manufacturer of expendable products for material cutting, material removal and
wear applications used in various industries. The Company also manufactures a
limited number of products (primarily bilge pumps) for the marine industry. The
Company markets its products through six product groups which are as follows:
(1) industrial products, (2) engineered products, (3) energy and construction
products, (4) electronics products, (5) consumer products, and (6) marine
products. The majority of the Company's products are made from either high-speed
steel or tungsten carbide. The Company's largest concentration of business is in
North America but it sells its products throughout the world.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     The policies utilized by the Company in the preparation of the consolidated
financial statements conform to generally accepted accounting principles, and
require management to make estimates and assumptions that affect the reported
amounts of assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual amounts could differ from these estimates.
 
     The significant accounting policies followed by the Company are described
below.
 
REVENUE RECOGNITION
 
     Revenue from the sale of the Company's products is recognized upon shipment
to the customer.
 
PRINCIPLES OF CONSOLIDATION
 
     The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries. All significant intercompany transactions and
balances are eliminated in consolidation.
 
INTERIM UNAUDITED FINANCIAL INFORMATION
 
     The interim consolidated financial information at September 30, 1997 and
for the nine months ended September 30, 1996 and 1997 and related disclosures in
the notes herein (including Note 18) is unaudited. However, in the opinion of
management, such information has been prepared on the same basis as the audited
consolidated financial statements and includes all adjustments, consisting only
of normal recurring adjustments, necessary for a fair presentation of the
results of operations for the periods presented. The interim results, however,
are not necessarily indicative of the results for any future period.
 
FOREIGN CURRENCY TRANSLATION
 
     The accounts of the Company's foreign subsidiaries are maintained in their
respective local currencies. The accompanying consolidated financial statements
have been translated and adjusted to reflect U.S. dollars on the bases presented
below.
 
     Assets and liabilities are translated into U.S. dollars at year-end
exchange rates. Income and expense items are translated at average rates of
exchange prevailing during the year. Adjustments resulting from the process of
translating the consolidated amounts into U.S. dollars are accumulated in a
separate translation adjustment account included in stockholders' equity. Common
stock and additional paid-in capital are translated at historical U.S. dollar
equivalents in effect at the date of acquisition. Foreign currency transaction
gains and losses are included in earnings currently. The Company recognized net
foreign currency transaction gains of $227, $540 and $599 for the years ended
December 31, 1994, 1995 and 1996, respectively.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
 
CASH
 
     For purposes of the consolidated statements of cash flows, the Company
considers all highly liquid investments with an original maturity of three
months or less to be cash. Cash overdrafts, if any, on the Company's
disbursement accounts are included in the balances outstanding under the
Company's revolving credit facilities.
 
CONCENTRATION OF CREDIT RISK
 
     The Company sells its products to distributors and end-users in the
industrial, energy and construction, electronics, engineered products, consumer
and marine markets. While most of the Company's business activity is with
customers located within North America, the Company also serves customers in
Europe and the Far East. The Company performs ongoing credit evaluations of its
customers and generally does not require collateral. The Company maintains
reserves for potential credit losses and historically such losses have been
within management's expectations. At December 31, 1996, the Company had no
significant concentrations of credit risk.
 
RELATIONSHIPS WITH SUPPLIERS
 
     The Company purchases tungsten carbide materials from multiple suppliers,
for which alternative suppliers also exist and are adequate. Although the
Company purchases the majority of its domestic high-speed steel requirements
from a single supplier, the Company believes that the supply of steel and the
number of alternative suppliers are adequate. The Company considers its
relationships with its primary suppliers to be strong.
 
INVENTORIES
 
     Inventories are stated at the lower of cost or market. Cost is determined
using the last-in, first-out (LIFO) method, for substantially all domestic
inventories. For various tax and statutory reasons, inventories of the Company's
foreign subsidiaries are stated at first-in, first-out (FIFO) cost. The effects
on the consolidated financial position and results of operations from applying
the FIFO method (versus the LIFO method) to certain inventories are immaterial.
If the FIFO method (which approximates replacement cost) had been used in
determining cost for all inventories, inventories would have been approximately
$5,181 and $5,675 higher at December 31, 1995 and 1996, respectively.
Inventories include the cost of materials, direct labor and manufacturing
overhead. Obsolete or unsaleable inventories are reflected at their estimated
net realizable values.
 
PROPERTY, PLANT AND EQUIPMENT
 
     Property, plant and equipment is carried at cost and is depreciated using
the straight-line method over the estimated useful lives of the assets which
range from 3 to 40 years. Properties held under capital leases are recorded at
the present value of the noncancelable lease payments over the term of the lease
and are amortized over the shorter of the lease term or the estimated useful
lives of the assets. Expenditures for repairs, maintenance and renewals are
charged to income as incurred. Expenditures which improve an asset or extend its
estimated useful life are capitalized. When properties are retired or otherwise
disposed of, the related cost and accumulated depreciation are removed from the
accounts and any gain or loss is included in income.
 
GOODWILL
 
     The excess of the purchase price over the fair value of net assets acquired
in business combinations is capitalized and amortized on a straight-line basis
over the estimated period benefited. The amortization period for all
acquisitions to date is 40 years. Amortization expense for the years ended
December 31, 1994, 1995 and 1996 was approximately $1,221, $2,636 and $4,279,
respectively. Accumulated amortization at December 31, 1995 and 1996 was
approximately $7,592 and $11,849, respectively. The carrying value of goodwill
is assessed for recoverability by management based on current and anticipated
conditions, including expected cash flows and

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
 
operating results generated by the underlying tangible assets. Management
believes that there has been no impairment at December 31, 1996.
 
OTHER ASSETS
 
     Other assets are primarily comprised of debt issuance and trademark costs.
At December 31, 1995, other assets also included an investment in Rule
Industries, Inc. stock as further described in Note 3. Debt issuance costs are
being amortized on a straight-line basis over the life of the related obligation
and trademarks are being amortized on a straight-line basis over 40 years.
Amortization expense for the years ended December 31, 1994, 1995 and 1996 was
approximately $270, $272 and $341, respectively. Accumulated amortization at
December 31, 1995 and 1996 was $3,471 and $3,568, respectively.
 
INCOME TAXES
 
     The Company accounts for income taxes under Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes" (FAS 109). Under FAS
109, the deferred tax provision is determined using the liability method,
whereby deferred tax assets and liabilities are recognized based upon temporary
differences between the financial statement and income tax bases of assets and
liabilities using presently enacted tax rates.
 
EARNINGS PER SHARE
 
     Fully diluted earnings per share primarily reflect the effects of
conversion of the Company's mandatorily redeemable convertible preferred
securities and elimination of the related dividends, net of applicable income
taxes (see Note 5). Primary earnings per share is computed by dividing net
income available to common stockholders by the weighted average number of common
and common equivalent shares outstanding during the period. Options under the
Company's employee and directors stock option plans are not included as common
stock equivalents for earnings per share purposes since they did not have a
material dilutive effect.
 
ENVIRONMENTAL LIABILITIES
 
     Environmental expenditures that relate to current operations are expensed
or capitalized as appropriate. Expenditures that relate to an existing condition
caused by past operations, and that do not contribute to current or future
revenue generation, are expensed. Liabilities are recorded when environmental
assessments and/or remedial efforts are probable, and the costs can be
reasonably estimated.
 
EMPLOYEE STOCK-BASED COMPENSATION
 
     The Company accounts for employee stock options and variable stock awards
in accordance with Accounting Principles Board No. 25, "Accounting for Stock
Issued to Employees" (APB 25). Under APB 25, the Company applies the intrinsic
value method of accounting. For employee stock options accounted for using the
intrinsic value method, no compensation expense is recognized because the
options are granted with an exercise price equal to the market value of the
stock on the date of grant. For variable stock awards accounted for using the
intrinsic value method, compensation cost is estimated and recorded each period
from the date of grant to the measurement date based on the market value of the
stock at the end of each period.
 
     During 1996, Statement of Financial Accounting Standards No. 123,
"Accounting for Stock-Based Compensation" (FAS 123), became effective for the
Company. FAS 123 prescribes the recognition of compensation expense based on the
fair value of options or stock awards determined on the date of grant. However,
FAS 123 allows companies to continue to apply the valuation methods set forth in
APB 25. For companies that continue to apply the valuation methods set forth in
APB 25, FAS 123 mandates certain pro forma disclosures as if the fair value
method had been utilized. See Note 12 for additional discussion.

     During the past three years, the Company has made several acquisitions
which have significantly expanded its product lines. These acquisitions were
each accounted for using the purchase method of accounting and financed
primarily through bank borrowings, resulting in an increase in the Company's
outstanding debt. Results of operations of each acquired company have been
included in the Company's consolidated financial statements from the date of
acquisition. The purchase price of each acquisition was allocated to the assets
acquired and liabilities assumed based on their estimated fair value at the date
of acquisition. The excess of purchase price over the estimated fair value of
net assets acquired was, in each instance, recorded as goodwill. Except for
Rule, CTD and Carbidie, the pro forma effects, individually and collectively, of
the acquisitions on the Company's consolidated results of operations and
financial position are not material.
 
     The following table sets forth pro forma information for the Company as if
the acquisitions of Rule, CTD and Carbidie had taken place on January 1, 1994
and the acquisition of Rule had taken place on January 1, 1995, respectively.
This information is unaudited and does not purport to represent actual revenue,
net income and earnings per share had the acquisitions actually occurred on
January 1, 1994 and 1995, respectively. The pro forma effects of Rule, had the
acquisition taken place on January 1, 1996, are not material.

     In connection with the Company's acquisition of Rule in January 1996, the
Company recorded a restructuring reserve of $2,600 in purchase accounting
primarily related to the closing of two Rule facilities (including the corporate
office) and the involuntary termination of a substantial number of Rule
employees. Of the $2,600 reserve, $1,240 related to employee severance costs,
$346 related to the closure of the two facilities, and $1,014 related to other
nonrecurring costs associated with terminating certain Rule operations. This
restructuring has resulted in a reduction in personnel and the elimination of
certain duplicate functions. The employee severance costs related to the
reduction of approximately 62 employees from the acquisition date. Of the total
$2,600 reserve, substantially all of the costs had been paid as of December 31,
1996.
 
     The Company, as part of the acquisition of CTD, recorded a restructuring
and plant consolidation liability of $10,480 in purchase accounting relating to
the consolidation of certain facilities of CTD into existing facilities of the
Company. The $10,480 liability included $8,430 in costs associated with plant
closures, $2,000 in severance pay and $50 in other costs. Substantially all of
these costs had been paid as of December 31, 1996.
 
     On March 27, 1997, the Company acquired the outstanding shares of Hanita
Metal Works, Ltd., an Israeli-based company, and its U.S. subsidiary Hanita
Cutting Tools, Inc. (collectively, Hanita) for approximately $20,800 (including
cash acquired) and assumed indebtedness of approximately $14,600. Hanita, with
its primary manufacturing, sales and distribution operations in Israel, is a
leading manufacturer of high-quality, high performance end mills and other
cutting tools for the metalworking industry. Hanita also sells and distributes
products around the world, including the United States. The acquisition was
accounted for using the purchase method of accounting and was financed through
the Company's existing unsecured credit facility. For the year ended December
31, 1996, Hanita had net sales of approximately $27,000. The pro forma effects
of the acquisition on the Company's results of operations are not material. The
results of operations of Hanita are included in the Company's consolidated
financial statements from the date of acquisition.

indebtedness to cash flow) payable quarterly on any unused portion of the
domestic and foreign revolving credit facilities. As discussed above, the
domestic revolving facility and the acquisition facility were replaced in
December 1996.

capital and debt to cash flow ratios and net worth levels. At December 31, 1995
and 1996, and at September 30, 1997, the Company was in compliance with such
provisions.

5. MANDATORILY REDEEMABLE CONVERTIBLE PREFERRED SECURITIES
 
     On April 24, 1996, the Company completed a private placement to
institutional investors of $115,000 of 6% Convertible Preferred Securities
(liquidation preference of $50 per Convertible Preferred Security). The
placement was made through the Company's wholly-owned subsidiary, Greenfield
Capital Trust (Trust), a newly-formed Delaware business trust. The securities
represent undivided beneficial ownership interests in the Trust. The sole asset
of the Trust is the $118,557 aggregate principal amount of the 6% Convertible
Junior Subordinated Deferrable Interest Debentures Due 2016 which were acquired
with the proceeds from the private placement of the Convertible Preferred
Securities and the offering and sale of Common Securities to the Company. The
Company's obligations under the Convertible Junior Subordinated Debentures, the
Indenture pursuant to which they were issued, the Amended and Restated
Declaration of Trust of the Trust and the Guarantee of Greenfield, taken
together, constitute a full and unconditional guarantee by Greenfield of amounts
due on the Convertible Preferred Securities. The Convertible Preferred
Securities are convertible at the option of the holders at any time into the
common stock of Greenfield at an effective conversion price of $41.25 per share
and are redeemable at Greenfield's option after April 15, 1999. The net proceeds
of the offering of approximately $110,746 were used by Greenfield to retire
indebtedness. A registration statement relating to resales of such Convertible
Preferred Securities was declared effective by the Securities and Exchange
Commission on September 26, 1996.
 
     Upon consummation of the merger described in Note 18, the effective
conversion price of the Convertible Preferred Securities was adjusted to
approximately $36.05.
 
6. LEASE COMMITMENTS
 
     The Company leases certain of its equipment under noncancelable lease
agreements. These agreements extend for a period of up to 42 months and contain
purchase or renewal options on a month-to-month basis. The leases are reflected
in the consolidated financial statements as capitalized leases in accordance
with the requirements of Statement of Financial Accounting Standards No. 13,
"Accounting for Leases."

     The deferred tax asset valuation allowance at December 31, 1996 primarily
represents excess deductible temporary differences over taxable temporary
differences for foreign operations and potential nonrealization of certain other
deferred tax assets. The tax benefits, if any, from the future recognition of
certain deductible temporary differences present at the date of the acquisition
of CTD and Rule, but not recognized at that time, will be applied to reduce
goodwill.
 
     The provision for income taxes differs from the amount of income tax
determined by applying the applicable U.S. statutory federal income tax rate to
pretax income as a result of the following differences:

8. RESTRUCTURING COSTS
 
     The results of operations for the year ended December 31, 1996 included
restructuring costs of $4,000 (approximately $2,400 net of related tax benefits,
or $0.15 per common share), on a primary basis. These costs were primarily
related to employee severance and certain other nonrecurring charges resulting
from the effects of the reorganization of the Company's business groups. The
restructuring costs included the costs associated with the combination or
elimination of certain functions or operations which were identified as
redundant. The $4,000 restructuring charge recorded in the third quarter
included $2,727 for employee-related costs consisting primarily

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
 
of severance costs, $585 for the noncash write-down of plant assets where
operations have been or will be terminated, and $688 for other nonrecurring
severance costs for personnel that have been terminated or will be terminated in
future periods. The employee severance costs relate to the reduction of
approximately 42 employees as of December 31, 1996 and future reductions of
approximately 28 employees. Of the total $4,000 charge, approximately $777 had
been incurred through December 31, 1996. The remaining accrual primarily relates
to employee severance costs and costs associated with the closure of two
facilities.
 
     During 1994, the Company recorded restructuring costs of $1,300 relating to
the consolidation of the plant in Switzerland into a plant in Germany. The
$1,300 charge is comprised of $700 in costs associated with plant closures and
relocation of machinery and equipment, $500 in severance costs related to
approximately 35 administrative staff and plant personnel at the closed Swiss
facility and $100 in other costs. The Company substantially completed the
restructuring by the end of 1994.
 
     The Company continues to evaluate its operations with an intent to
streamline operations, improve productivity and reduce costs and may implement
additional rationalization programs in the future.
 
9. RETIREMENT PLANS
 
     The Company offers substantially all of its domestic employees a retirement
savings plan under Section 401(k) of the Internal Revenue Code. Employees may
elect to enter a written salary deferral agreement under which a maximum of 15%
of their salaries may be contributed to the plan, subject to aggregate limits
required under the Internal Revenue Code. The Company is required to make a
mandatory contribution of 2% of qualified employee earnings. In addition, the
Company will match a percentage of the employees' contribution up to a specified
maximum percentage of their salaries and may make a discretionary contribution
from profits upon resolution of its Board of Directors. For the years ended
December 31, 1994, 1995 and 1996, the Company made contributions to the defined
contribution plans of approximately $2,448, $3,406 and $3,923, respectively.
 
     CTD, Carbidie and AMT had defined benefit pension plans covering
substantially all domestic employees with the exception of AMT non-union
employees when they were acquired by the Company. All of these plans were frozen
in 1995, and benefits were frozen at 1995 levels. In addition, Rule had a
defined benefit pension plan for certain employees for which the benefits had
been frozen prior to the Company's acquisition of Rule in January 1996. The
Company's funding policy with respect to such plans is to contribute annually
the minimum amount required under ERISA. Plan assets include marketable equity
securities, U.S. government securities, federal agency obligations, corporate
debt instruments, money market funds and other fixed income securities.
 
     In connection with the CTD and Carbidie acquisitions in 1994, the Company
recorded an aggregate net liability of $6,051 in purchase accounting
representing the excess of the estimated projected benefit obligation (PBO) over
the fair value of plan assets. During 1996, the Company recorded a net liability
of $700 in purchase accounting for the excess of the PBO over the fair value of
the plan assets in connection with the Rule acquisition.
 
     The following tables set forth the defined benefit pension plans' net
periodic pension costs for the years ended December 31, 1995 and 1996 and the
plans' net funded status, amounts recorded in the consolidated balance sheet,
and other summary information at December 31, 1995 and 1996:

10. POSTRETIREMENT BENEFITS
 
     Under Statement of Financial Accounting Standards No. 106, "Employers'
Accounting for Postretirement Benefits Other Than Pensions," the Company is
required to recognize the cost of providing health care and other benefits to
retirees over the term of the employees' service. Prior to the acquisitions of
CTD and Carbidie, the Company provided no postretirement benefits other than
those related to the 401(k) plans described in Note 9. CTD and a certain other
subsidiary provides health care insurance benefits to certain of its retired
employees. All of these plans were frozen in 1995, and benefits were frozen at
1995 levels. In connection with the CTD acquisition in 1994, the Company
recorded a liability of $11,939 in purchase accounting representing the
estimated discounted present value of the expected future retiree benefits
attributed to employees' service rendered in periods prior to Greenfield's
acquisition.
 
     The following tables set forth the plans' net periodic postretirement
benefit cost for the years ended December 31, 1995 and 1996, the accumulated
postretirement benefit obligation (APBO) at December 31, 1995 and 1996 and other
summary information:

     The assumed health care cost trend rate used in measuring the APBO for 1995

health care cost trend rates were increased by 1%, the APBO for 1995 and 1996
would have increased approximately $558 and $434, respectively.

     There are no plan assets and the Company expects to continue to fund these
benefit costs on a pay-as-you-go basis. During 1995 and 1996, the Company made
payments of approximately $1,018 and $1,400, respectively, related to these
benefits.
 
11. 1993 EXECUTIVE STOCK OPTIONS
 
     In 1993, the Company established the 1993-1 Executive Stock Option Plan
(1993-1 Plan) and granted to certain officers of Rogers Tool Works, Inc., a
wholly-owned subsidiary of the Company (RTW), non-qualified stock options to
purchase an aggregate of 438,258 shares of common stock at a price of $0.51 per
share, subject to adjustment, in exchange for the cancellation of RTW shares
held by these officers. In addition, the Company cancelled the promissory notes
of each of these officers issued to finance the purchase of their RTW shares.
The exercise price with respect to the options granted was determined to
preserve the original purchase price per share of the RTW shares cancelled. The
options became exercisable as to 25% of the shares issuable thereunder on
January 26, 1994, and as to a cumulative 35%, 50% and 100% of the shares
issuable thereunder on each succeeding six-month anniversary thereof. As of
December 31, 1995 all of the options had been exercised. During the years ended
December 31, 1994 and 1995, 153,367 and 284,891 shares, respectively, were
issued in connection with the 1993-1 Plan.
 
     In 1993, the Company also adopted the 1993-2 Executive Stock Option Plan
(1993-2 Plan) pursuant to which nonqualified stock options were granted to
certain existing shareholders prior to the initial public offering to acquire an
aggregate 453,350 shares of the Company's common stock, subject to adjustment,
by tendering existing common stock in payment thereof. The exercise price of all
options was the current market price on the date of exercise and all options
were exercised only by exchanging shares of previously owned common stock. The
grant and exercise of options under the 1993-2 Plan did not result in any
increase in the beneficial ownership of common stock by the plan participants
from the number of shares owned immediately after the initial public offering.
Under the terms of the 1993-2 Plan, the options were exercised immediately after
the initial public offering and the shares of common stock issued thereunder
became freely transferable by each participant as to 25% of the shares issuable
to such participants on January 31, 1994 and as to a cumulative 35%, 50% and
100% of the shares issuable to such participant on each succeeding six-month
anniversary thereof. The shares tendered in exercise of options granted under
the 1993-2 Plan were issued under promissory notes due in 1998 through 2002. The
notes are reflected in stock subscriptions receivable, included in additional
paid-in capital and other, in the accompanying consolidated financial
statements.
 
12. STOCK OPTION AND STOCK INCENTIVE PLANS
 
STOCK OPTION PLANS
 
     The Company has three stock options plans: the Employee Stock Option Plan
(Employee Plan), the 1995 Directors Non-Qualified Stock Option Plan (Directors
Plan) and the 1993 Directors Non-Qualified Stock Option Plan (1993 Directors
Plan).
 
     The Employee Plan provides for the granting of options to purchase up to
1,000,000 shares of common stock to the Company's executive officers and key
employees at prices equal to the fair market value of the stock on the date of
grant. The Employee Plan was amended effective May 6, 1997, to, among other
things, increase the number of options to purchase shares of common stock from
1,000,000 to 2,000,000. Options outstanding at December 31, 1996 entitle the
holders to purchase common stock at prices ranging between $16.00 and $37.00 per
share, subject to adjustment. Options shall become exercisable with respect to
one-fourth of the shares covered thereby on each anniversary of the date of
grant, commencing on the second anniversary of such date. The right to exercise
the options expires ten years from the date of grant, or earlier if an option
holder ceases to be employed by the Company.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
 
     The Directors Plan provides for the granting of options to purchase up to
125,000 shares of common stock to the Company's Directors who are not employees
of the Company at prices equal to the fair market value of the stock on the date
of grant. Options are granted to each eligible Director on the date such person
is first elected to the board of directors of the Company and on each subsequent
re-election date. The Directors Plan was approved in May 1996 by the
stockholders. Options outstanding at December 31, 1996 entitle the holders to
purchase common stock at a price of $37.00 per share, subject to adjustment.
Options granted upon re-election shall become exercisable in full on the first
anniversary of such date. All other options shall become exercisable with
respect to one-fourth of the shares covered thereby on each anniversary date of
the date of grant, commencing on the second anniversary of such date. The right
to exercise the options expires ten years from the date of grant, or earlier, if
an option holder ceases to be a Director of the Company.
 
     The 1993 Directors Plan provides for the granting of options to purchase up
to 100,000 shares of common stock to the Company's Directors who are not
employees of the Company at prices equal to the fair market value of the stock
on the date of grant. Options are granted to each eligible Director on the date
such person is first elected to the board of directors of the Company. Options
outstanding at December 31, 1996 entitle the holders to purchase common stock at
prices ranging between $15.50 and $25.75 per share, subject to adjustment.
Options shall become exercisable with respect to one-fourth of the shares
covered thereby on each anniversary of the date of grant, commencing on the
second anniversary of such date. The right to exercise the options expires ten
years from the date of grant, or earlier if an option holder ceases to be a
Director of the Company. Subsequent to the May 1996 approval of the Directors
Plan, no further grants will be issued under the 1993 Directors Plan.
 
     A summary of the status of the Company's stock option plans as of December
31, 1994, 1995 and 1996, and changes during the years then ended are presented

     In connection with the resignation of a member of the Company's Board of
Directors, in 1994 the Company exchanged options for 10,000 shares of common
stock previously granted to the Director with a warrant to purchase 10,000
shares of common stock at an exercise price equal to the exercise price of the
options.
 
STOCK INCENTIVE PLANS
 
     The Company has two stock incentive plans: the 1995 Equity Incentive Plan
(Incentive Plan) and the 1995 Restricted Stock Bonus Plan (Ownership Plan). Both
plans were approved in May 1996 by the stockholders of the Company.
 
     The Incentive Plan provides for the granting of up to 273,000 shares of
common stock to certain senior executives of the Company in time-lapse
restricted stock, performance contingent restricted stock and performance
shares. Time-lapse restricted stock vests in one-third increments over a
three-year period commencing four years after the date of the award. Performance
contingent restricted stock is earned when the price for the Company's stock
reaches certain predetermined levels, and then vests over a three- or five-year
period. Performance shares are earned based on attainment of a predetermined
four-year cumulative earnings per share level. Attainment of between 50% and
200% of the predetermined objective will entitle the participants to receive
restricted performance shares of between 50% and 200% of the target award, which
then vest over a three-year period. No performance shares are earned if less
than 50% of the performance objective is obtained.
 
     The Ownership Plan provides for the issuance of up to 250,000 shares of
common stock to certain employees, by allowing such employees to elect to defer
up to 50% of their annual cash bonus and receive, in lieu thereof, shares of the
Company's common stock. The Company will increase the employees' deferred bonus
by either 20% or 35% (depending on the employees' selection of 3 or 5 years,
respectively, for the restriction period).
 
     Shares issued under these plans are restricted and are subject to
forfeiture upon termination of employment. During the period that the shares are
restricted, award holders have the right to vote and to receive dividends on
such shares.
 
     A summary of stock earned and issued pursuant to the Incentive Plan and
Ownership Plan for the year ended December 31, 1996 follows:

     The Company awarded up to 273,000 shares of restricted stock to certain
senior executives under the Incentive Plan, subject to the attainment of certain
performance levels, as discussed above. The weighted average fair value of the
shares on the grant date was $30.73. The Company applies APB 25 and related
interpretations in accounting for stock awards under the Incentive and Ownership
Plans. Under APB 25, the Company recorded $1,500 of compensation expense during
1996 attributable to these awards, which is included in selling, general and
administrative expenses in the 1996 consolidated statement of operations.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
 
     Shares which have been issued but which remain restricted are recorded as
deferred compensation, a reduction to additional paid-in capital. The increase
in additional paid-in capital of $761 during 1996 represents the issuance of
executive stock awards and is net of this deferred compensation. As the shares
vest and become unrestricted, the deferred compensation will be recorded as
compensation expense and additional paid-in capital will increase.
 
PRO FORMA DISCLOSURES
 
     The Company applies APB 25 and related interpretations in accounting for
its stock option plans. Accordingly, except for the Incentive and Ownership
Plans as described above, no compensation cost has been recognized for the stock
options because the options were granted with an exercise price equal to the
stock price on the date of grant. Had compensation costs for the Company's stock
option plans been determined based on the fair value of the options on the grant
dates consistent with the methodology prescribed by FAS 123, the Company's net
income and earnings per share would have been reduced to the pro forma amounts
indicated below. Due to the adoption of the methodology prescribed by FAS 123,
the pro forma results shown below only reflect the impact of options and stock
awards granted in 1995 and 1996. Because future options and stock awards may be
granted, the pro forma impact for 1995 and 1996 is not necessarily indicative of
the impact in future years.

13. RELATED PARTIES
 
     Harbour Group Investments, L.P. (HGI, L.P.) was the Company's principal
stockholder prior to HGI, L.P.'s sale of substantially all of its shares in a
secondary stock offering in March 1994. Under terms of a corporate development
consulting and advisory services agreement, the Company incurred fees totaling
$1,109, $445 and $580 in 1994, 1995 and 1996, respectively, payable to an
affiliate of HGI, L.P. related to corporate development services provided in
identifying, negotiating and consummating certain acquisitions.
 
     Under terms of a management consulting and advisory services agreement,
Harbour Group, Ltd. (HGL), an affiliate of HGI, L.P., charges the Company for
direct management and administrative services provided to the Company based on
HGL's approximate costs for such services. These charges totaled approximately
$250, $182 and $53 for the years ended December 31, 1994, 1995 and 1996,
respectively, and are reflected in selling, general and administrative expenses

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
 
     At December 31, 1995 and 1996, a member of HGL management owned 80,000
shares of the Company's common stock partially financed with promissory notes
totaling $101 due in 1998 through 2003. The notes are reflected in stock
subscriptions receivable, included in additional paid-in capital and other, in
the accompanying consolidated financial statements.
 
14. COMMITMENTS AND CONTINGENCIES
 
     The Company is involved in certain claims and legal proceedings in which
monetary damages are sought. The Company is vigorously contesting these claims.
However, resolution of these claims is not expected to occur quickly and their
ultimate outcome presently cannot be predicted. It is the opinion of management
that any liability of the Company for claims or proceedings will not materially
affect its financial position.
 
     In connection with the acquisition of CTD, the Company recorded a liability
of $2,600 in purchase accounting for certain estimated environmental clean-up
costs to be incurred relative to acquired CTD facilities. This estimated
potential liability, which is included in other accrued liabilities, has not
been reduced for any expected proceeds from other potentially responsible third
parties. At December 31, 1996, the liability balance was approximately $2,200.
 
15. SEGMENT INFORMATION
 
     Worldwide operations data, as required by Statement of Financial Accounting
Standards No. 14, "Financial Reporting for Segments of a Business Enterprise,"
are listed below. Profitability of the Company's foreign operations by
geographic area was determined based on ultimate sales to unaffiliated
customers. Income from operations was included in the geographic area of the
entity transacting the final sale. Intercompany sales have been eliminated in
consolidation.

18. SUBSEQUENT EVENTS (UNAUDITED)
 
     On October 10, 1997, the Company entered into a definitive merger agreement
with Kennametal Inc. (Kennametal), whereby Kennametal Acquisition Corp. (a
wholly-owned subsidiary of Kennametal) commenced a tender offer on October 17,
1997 for all of the outstanding shares of the Company for $38 per share. The
tender offer expired on November 14, 1997 and approximately 98% of the Company's
shares were tendered. The merger was completed on November 18, 1997. Under the
terms of the merger agreement, all outstanding options to acquire shares of the
Company were cancelled in exchange for a payment equal to the difference between
$38 per share and the strike price.
 
     In the fourth quarter of 1997, pursuant to a plan approved by the Company's
board of directors, the Company recorded a $11.5 million charge for nonrecurring
expenses primarily related to the restructuring of the Company's South
Deerfield, Massachusetts operations. These costs primarily included write-downs
of inventory

and machinery and equipment to estimated net realizable values, severance costs
and other miscellaneous expenses relative to the Company's decision to
discontinue the manufacture and sale of certain low margin product lines. The
restructuring will result in a reduction in personnel, thereby eliminating
excessive costs and redundancies in future periods. The Company expects to
record additional nonrecurring expenses of approximately $2.0 million in 1998
related to the rearrangement of the remaining operations at its South Deerfield,
Massachusetts facility.

                               PROSPECTUS SUMMARY
 
     The following summary is qualified in its entirety by the more detailed
information and the consolidated financial statements and the related notes
thereto appearing elsewhere in this Prospectus. On November 17, 1997, Kennametal
Acquisition Corp. ("Acquisition Corp."), a wholly-owned subsidiary of
Kennametal, purchased in accordance with its tender offer (the "Tender Offer")
approximately 98% of the outstanding common stock of Greenfield pursuant to an
Agreement and Plan of Merger dated as of October 10, 1997 (the "Merger
Agreement"), among Kennametal, Greenfield and Acquisition Corp. and, on November
18, 1997, Acquisition Corp. was merged into Greenfield and Greenfield became a
wholly-owned subsidiary of Kennametal. Except as otherwise noted or unless the
context otherwise requires, (i) "fiscal" in connection with a year means the 12
months ended June 30 of the calendar year specified, and (ii) the information in
this Prospectus assumes no exercise of the Underwriters' over-allotment options.
Unless the context indicates otherwise, any reference in this Prospectus to the
"Company" or "Kennametal" refers to Kennametal Inc. and its consolidated
subsidiaries other than Greenfield.
 
     This Prospectus contains certain forward-looking statements (as such term
is defined in the Securities Act) concerning the Company's operations,
performance and financial condition, including, in particular, the likelihood of
the Company's success in integrating the acquisition of Greenfield. These
statements are based upon a number of assumptions and estimates which are
inherently subject to significant uncertainties and contingencies, many of which
are beyond the control of the Company. Actual results may differ materially from
those expressed or implied by such forward-looking statements to the extent that
economic conditions in the United States, Europe and, to a lesser extent, the
Asia Pacific region change from the Company's expectations and to the extent
that the Company does not effectively integrate the acquisition of Greenfield
and achieve expected synergistic benefits.
 
                                  THE COMPANY
 
     The Company is a vertically integrated global manufacturer, marketer and
distributor of a broad range of consumable tools, supplies and services for the
metalworking, mining and highway construction industries. Kennametal specializes
in developing and manufacturing tools utilizing tungsten carbide powder
metallurgy for the three primary metalcutting methods--turning, milling and
drilling. In addition, through its 80%-owned subsidiary, JLK Direct Distribution
Inc. ("JLK"), the Company markets and distributes a broad line of consumable
metalcutting tools, as well as abrasives, machine tool accessories, hand tools,
measuring equipment and other industrial supplies used in the metalworking
industry. The Company is a recognized leader in turning and milling consumable
metalcutting tools and believes it is the largest North American and the second
largest global provider of consumable metalcutting tools and supplies.
Leveraging its expertise in tungsten carbide powder metallurgy, the Company has
developed innovative consumable tools for the mining and construction industries
and believes it is the largest global manufacturer, marketer and distributor of
such tools to these markets.
 
     In November 1997, the Company acquired Greenfield Industries, Inc., the
leading North American manufacturer of drilling and other rotary high-speed
steel consumable metalcutting tools for the metalworking industry. Kennametal
believes that Greenfield's operations strongly complement its core businesses
and that the acquisition of Greenfield, in addition to providing the Company
with opportunities for substantial cost savings, offers significant strategic
benefits, including: (i) providing an important new channel of traditional
industrial distributors through which to sell the Company's products; (ii)
expanding and enhancing the Company's line of drilling products; (iii) allowing
the Company to diversify into new markets such as certain wear products by
leveraging its material science expertise in tungsten carbide powder metallurgy;
and (iv) providing the opportunity to introduce and sell each company's products
into the markets served by the other company.
 
     End users of the Company's metalworking products include manufacturers and
suppliers in the aerospace, automotive, construction and farm machinery,
railroad equipment, power generation and transmission equipment, home appliance,
electrical equipment, and oil field services and gas exploration industries. The
Company markets its products through: a technically skilled direct sales force;
JLK's catalogs, showrooms and other direct marketing efforts; JLK's integrated
industrial supply programs; and, with the acquisition of Greenfield, a network
of traditional industrial distributors. This multi-channel marketing approach
enables the Company to meet the
 
                                       S-4
<PAGE>   206
 
varying needs of metalworking customers of all sizes which range from same-day
ordering and rapid delivery of products to outsourcing the entire procurement
and inventory management process for metalworking and related products. The
Company estimates there are approximately 250,000 metalworking industrial sites
in the United States. The Company's multi-channel distribution network,
comprehensive product offering and global presence allow customers of all sizes
the advantage of a single source of supply for most metalworking needs.
 
     The Company believes five significant trends are currently impacting the
metalworking industry: (i) consolidation of fragmented distribution channels as
customers seek a single source of supply for their metalworking needs; (ii)
increasing demand from large customers to outsource procurement and inventory
management processes through integrated supply programs; (iii) growing demand
for suppliers that can provide a complete selection of tools, supplies and
services globally; (iv) demand for world class capabilities including customer
service, technical application support and information and product technology
while, at the same time, maintaining or reducing costs; and (v) continuing
advances in customers' metalworking manufacturing technology requiring more
technically advanced tools. These factors are resulting in a restructuring and
consolidation in the metalworking industry as tooling manufacturers and
distributors are forced to either become more competitive or seek stronger
partners. The Company's business strategy is designed to capitalize on these and
other trends.
 
BUSINESS STRATEGY
 
     The Company's objective is to become the supplier of first choice of
consumable tools, related supplies, and services to the worldwide metalworking
industry and to other industries which can benefit from tungsten carbide
products. The Company believes its market-leadership position results from the
successful implementation of its business strategy, the major elements of which
include:
 
     - Expanding Customer Base Through Multi-Channel Distribution.  The Company
       seeks to access potential customers through all primary distribution
       channels. The Company serves its traditional base of large and
       medium-sized metalworking customers through a direct sales force. JLK
       direct markets a broad range of tiered ("good," "better" and "best")
       metalworking consumables and other related products targeted at small and
       medium-sized metalworking customers and offers integrated supply programs
       targeted at large industrial metalworking customers. The acquisition of
       Greenfield, which sells its consumable tools, related products and
       services through a network of more than 2,500 traditional industrial
       distributors, provides Kennametal with access to approximately 50% of the
       North American metalworking market.
 
     - Providing Most Complete Product Offering.  The Company seeks to provide
       the most complete and comprehensive product offering in the metalworking
       industry. As a result of various acquisitions and internal development,
       the Company markets and distributes what it believes is one of the
       broadest lines of tools and services typically used by metalworking
       customers. The recent acquisition of Greenfield and its consumable
       high-speed steel rotary cutting tools and related products provides the
       Company with the capability to manufacture all of the major consumable
       tools needed by customers in their metalcutting manufacturing processes.
 
     - Expanding Strong Global Presence.  Kennametal is committed to growing its
       global presence as demonstrated by its position as the second largest
       provider of tools to the European metalworking industry, the world's
       largest metalworking market, and its plans to expand its presence in the
       Asia Pacific region. The Company recently completed construction of a
       cutting tool manufacturing facility in Shanghai, China, for a total
       investment of about $20 million, and has increased to 100% its ownership
       interest in a sales and marketing subsidiary in Japan. The Company also
       has targeted marketing efforts in Eastern Europe and Russia and other
       developing countries.
 
     - Providing Superior Customer Service, Product Availability, and Technical
       Support.  The Company's skills in rapidly filling orders, maintaining
       high levels of product availability and providing technical product
       application support are vital to the ability of its metalworking
       customers to meet their production and delivery schedules in a cost
       effective manner. Kennametal's sophisticated order entry and inventory
       management systems enable the Company to ship more than 90 percent of its
       products from stock. In addition, the Company's technically skilled
       direct sales force of more than 700 persons provide on-site product
       selection and application support to enable customers to optimize their
       metalcutting processes.
 
                                       S-5
<PAGE>   207
 
       The addition of Greenfield's more than 70 technical specialists broadens
       the Company's technical support capability into high-speed steel drilling
       applications.
 
     - Maintaining Leadership in Product Innovation.  As a result of its
       commitment to research and development, the Company has brought to market
       during the past few years a number of new or improved metalcutting
       products. The exacting requirements of modern high-precision
       metalcutting, along with advances in manufacturing technology, exacting
       manufacturing specifications, and new workpiece materials are driving the
       demand for new and improved consumable tools and systems capable of
       achieving superior technical performance with high and uniform quality.
       The Company believes that its reputation for supplying high quality and
       technologically innovative consumable metalcutting tools and supplies to
       the metalworking industry has been very significant in achieving its
       market position.
 
     - Leveraging Use of Information Technology.  The Company's decision to
       invest nearly $40 million in a business information system utilizing SAP
       R-3 software demonstrates its commitment to the use of information
       technology. This system, which is expected to be fully operational in
       fiscal 1999, will link sales, distribution, manufacturing, purchasing and
       accounting activities at all major sites throughout Kennametal and is
       designed to enhance customer service, operational effectiveness and
       management decision-making.
 
     In addition to the above business strategies, the Company seeks to continue
to improve operating efficiencies as well as to pursue selected acquisitions
that enhance its distribution channels, complement its existing product
offerings and strengthen its geographic presence.
 
                              RECENT DEVELOPMENTS
GREENFIELD ACQUISITION
 
     On November 17, 1997, the Company purchased in the Tender Offer
approximately 98% of Greenfield's common stock and acquired the balance by a
merger on the following day. The total purchase price for the acquisition of
Greenfield (including estimated transaction costs and assumed Greenfield debt
and convertible redeemable preferred securities of approximately $320 million)
is estimated to be $1.0 billion. Greenfield is the largest North American
manufacturer of consumable rotary metalcutting tools as well as a leading
manufacturer of consumable tools and related products, wear products and marine
products.
 
NEW BANK CREDIT FACILITY
 
     In connection with the acquisition of Greenfield, the Company, on November
17, 1997, entered into a $1.4 billion credit agreement with the banks named
therein (the "New Bank Credit Facility") under which, as of November 18, 1997,
the Company had borrowed $500 million in term loans and approximately $300
million in revolving credit loans. The proceeds from the loans were principally
used to pay for the shares of common stock of Greenfield purchased in the Tender
Offer and the merger, to pay transaction costs, to refinance certain
indebtedness of Greenfield and to refinance certain indebtedness of the Company.
 
OTHER ACQUISITIONS
 
     The Company recently acquired Rubig G.m.b.H. of Munich, Germany, Presto
Engineers Cutting Tools Limited of Sheffield, United Kingdom, and Car-Max Tool &
Cutter Sales, Inc. The companies had aggregate annual sales of approximately $46

acquire GRS Industrial Supply Company, with annual sales of approximately $20
million in 1996.
 
FELINE PRIDES OFFERING
 
     Concurrently with the Offerings, the Company and Kennametal Financing I, a
Delaware business trust the common securities of which are owned by the Company,
are undertaking the FELINE PRIDES Offering of $       ,000,000 FELINE PRIDES(SM)
($       ,000,000 if the underwriters for the FELINE PRIDES(SM) exercise their

                              RECENT DEVELOPMENTS
GREENFIELD ACQUISITION
 
     On October 10, 1997, Kennametal and Acquisition Corp. entered into the
Merger Agreement with Greenfield pursuant to which Acquisition Corp. commenced
on October 17, 1997, the Tender Offer for all of the outstanding shares of
common stock of Greenfield at $38 per share and purchased on November 17, 1997,
approximately 16,179,976 shares (98% of the outstanding) of Greenfield's common
stock. The Merger occurred on November 18, 1997, and Greenfield became a
wholly-owned subsidiary of Kennametal on that date. The total purchase price for
the acquisition of Greenfield (including estimated transaction costs and assumed
Greenfield debt and convertible redeemable preferred securities of approximately
$320 million) is estimated to be $1.0 billion. There can be no assurance that
the Company will effectively integrate and manage the acquired business or
retain the management and the numerous distributorship customers of Greenfield.
In addition there can be no assurance that the anticipated benefits of the
Greenfield acquisition will be achieved. If Kennametal does not successfully
integrate and manage the acquisition, there could be a material adverse effect
on the Company.
 
NEW BANK CREDIT FACILITY
 
     In connection with the acquisition of Greenfield, the Company, on November
17, 1997, entered into the New Bank Credit Facility with BankBoston, N.A.,
Deutsche Bank AG, New York Branch and/or Cayman Islands Branch, Mellon Bank,
N.A. and PNC Bank, National Association. As of November 18, 1997, the Company
had borrowed $500 million in term loans and approximately $300 million in
revolving credit loans under the New Bank Credit Facility. The proceeds from the
loans were principally used to pay for the shares of common stock of Greenfield
purchased in the Tender Offer and the Merger, to pay transaction costs, to
refinance certain indebtedness of Greenfield, including purchasing convertible
redeemable preferred securities, and to refinance certain indebtedness of the
Company. Subject to certain conditions, the New Bank Credit Facility permits
revolving credit loans of up to $900 million for working capital requirements,
capital expenditures, and general corporate purposes. The New Bank Credit
Facility initially is secured by all of the stock of certain of Kennametal's
significant domestic subsidiaries, by guarantees of certain of such subsidiaries
and by 65% of the stock of Kennametal's significant foreign subsidiaries. The
New Bank Credit Facility contains various restrictive covenants and affirmative
covenants requiring the maintenance of certain financial ratios. The term loans
under the New Bank Credit Facility are subject to mandatory prepayments
commencing on November 30, 1998 and all loans mature on August 31, 2002.
Proceeds from the Offerings will be used to prepay term loans under the New Bank
Credit Facility. See "Capitalization," "Use of Proceeds" and "Management's
Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources--Financial Condition."
 
OTHER ACQUISITIONS
 
     The Company recently acquired Rubig G.m.b.H. of Munich, Germany, a marketer
of carbide precision tools for milling, drilling and other metalcutting
applications, Presto Engineers Cutting Tools Limited of Sheffield, United
Kingdom, a manufacturer of industrial high-speed steel cutting tools, and
Car-Max Tool & Cutter Sales, Inc., which is engaged in the distribution of
metalcutting tools and industrial supplies in the Midwest. The companies had
aggregate annual sales of approximately $46 million in 1996. The Company has
recently entered into an agreement to acquire GRS Industrial Supply Company,
which is engaged in the distribution of metalcutting tools and industrial
supplies in the Midwest, with annual sales of approximately $20 million in 1996.
 
FELINE PRIDES OFFERING
 
     Concurrently with the Offerings, the Company and Kennametal Financing I, a
Delaware business trust the common securities of which are owned by the Company,
are offering $          ,000,000 FELINE PRIDES ($          ,000,000 if the
underwriters for the FELINE PRIDES exercise their over-allotment option in
full). The Offerings are not contingent upon the consummation of the FELINE
PRIDES Offering and the FELINE PRIDES Offering is not contingent upon the
consummation of the Offerings. The net proceeds to the Company from the sale of
FELINE PRIDES will be used to prepay term loans under the New Bank Credit
Facility. This Prospectus does not constitute an offer to buy or the
solicitation of an offer to sell the securities being offered by the FELINE
PRIDES Offering. The FELINE PRIDES Offering will be made only by means of the
FELINE PRIDES Offering prospectus.

                                USE OF PROCEEDS
 
     The net proceeds to be received by the Company from the sale of the shares
of Common Stock, after deducting estimated underwriting discounts and expenses
of the Offerings payable by the Company, are expected to be approximately $
million (or approximately $     million if the Underwriters' over-allotment
options are exercised in full). See "Underwriting." The net proceeds from the
FELINE PRIDES Offering (assuming it is completed and the over-allotment option
is not exercised) is estimated to be $     million. The net proceeds from the
Offerings and the FELINE PRIDES Offering will be used to prepay term loans under
the New Bank Credit Facility, which indebtedness was incurred by the Company in
connection with the acquisition of Greenfield, and has a weighted average
interest rate of   %.

     The Company has paid cash dividends in every quarter since fiscal 1947. The
Board of Directors intends to continue its present policy of declaring regular
quarterly dividends when justified by the financial condition of the Company.
The amount of future dividends, if any, will depend on general business
conditions encountered by the Company, earnings, financial condition and capital
requirements of the Company, and such other factors as the Board of Directors
may deem relevant. The payment of dividends is subject to compliance with
certain financial covenants in the New Bank Credit Facility (see "Description of
Common Stock--Covenant Restrictions") and will be subject to certain
restrictions in connection with the FELINE PRIDES Offering (see "Description of
the FELINE PRIDES Offering").

             PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION
 
     The following Pro Forma Condensed Consolidated Statements of Income, the
Pro Forma Condensed Consolidated Balance Sheet and the pro forma data under
"Prospectus Summary--Summary Condensed Consolidated Financial Information" are
based on the historical financial statements of the Company and Greenfield
adjusted to give effect to the acquisition of Greenfield, the Offerings and the
FELINE PRIDES Offering. The Pro Forma Condensed Consolidated Statements of
Income for the year ended June 30, 1997, and for the three months ended
September 30, 1997, assume that the acquisition of Greenfield occurred as of the
first day of the Company's 1997 fiscal year (July 1, 1996). Since Greenfield has
a fiscal year-end of December 31, the historical information included in the Pro
Forma Condensed Consolidated Statement of Income for the year ended June 30,
1997 has been derived from Greenfield's operating results for the twelve months
ended June 30, 1997. The Pro Forma Condensed Consolidated Balance Sheet gives
effect to the acquisition of Greenfield, the Offerings and the FELINE PRIDES
Offering as if they had occurred on September 30, 1997.
 
     The pro forma financial information reflects the purchase method of
accounting for the acquisition of Greenfield, and accordingly is based on
estimated purchase accounting adjustments that are subject to further revision
depending upon completion of appraisals or other studies of the fair value of
Greenfield's assets and liabilities. Final purchase accounting adjustments will
differ from the pro forma adjustments presented herein and described in the
accompanying notes due to the results of operations of Greenfield from September
30, 1997, to the date of closing (November 18, 1997). See Note 18 to the
Company's consolidated financial statements included herein.
 
     The pro forma financial information reflects certain assumptions described
above and in the Notes to Pro Forma Condensed Consolidated Statements of Income
and Pro Forma Condensed Consolidated Balance Sheet which follow. The pro forma
financial information, including notes thereto, should be read in conjunction
with the consolidated financial statements of the Company and of Greenfield, and
the related notes thereto, and "Management's Discussion and Analysis of
Financial Condition and Results of Operations" included elsewhere in this
Prospectus. The pro forma financial information is provided for informational
purposes only and does not purport to present what the Company's results of
operations would actually have been if the acquisition of Greenfield had
occurred on the assumed dates, as specified above, or to project the Company's
financial condition or results of operations for any future period. See "Recent
Developments--Greenfield Acquisition" and "Business."

                            YEAR ENDED JUNE 30, 1997
 
(a) Represents additional depreciation expense related to excess purchase price
    assigned to property, plant and equipment.
 
(b) Represents amortization of excess purchase price allocated to goodwill over
    40 years of approximately $15.5 million less the elimination of historical

</TABLE>
 
(b) Reflects the costs related to the restructuring of Greenfield's South
    Deerfield, Massachusetts operations. In November 1997, Greenfield recorded
    an $11.5 million charge for non-recurring expenses primarily related to the
    restructuring of its South Deerfield operations. These costs primarily
    included inventory and machinery and equipment reserves, severance costs and
    other miscellaneous expenses related to Greenfield's decision to discontinue
    the manufacture and sale of certain low-margin product lines. The
    restructuring will result in a reduction in personnel, thereby eliminating
    excessive costs and redundancies in future periods. Greenfield also expects
    to record additional non-recurring expenses of approximately $2.0 million in
    1998 related to the further restructuring of its South Deerfield operations.
    These amounts are not included in the restructuring charge.

    $13.1 million to establish the New Bank Credit Facility.

    $1,024.0 million to: (i) acquire Greenfield (approximately $665.5 million);
    (ii) repay approximately $230.4 million of certain debt of Greenfield and
    Kennametal; (iii) repay $115.0 million of outstanding indebtedness of
    Greenfield-obligated, mandatorily redeemable convertible preferred
    securities of subsidiary Greenfield Capital Trust; and (iv) pay transaction
    fees of approximately $13.1 million related to the New Bank Credit Facility.

    related to the FELINE PRIDES.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
RESULTS OF OPERATIONS
 
THREE MONTHS ENDED SEPTEMBER 30, 1997 COMPARED TO THREE MONTHS ENDED SEPTEMBER
30, 1996
 
     SALES AND MARKETS.  During the quarter ended September 30, 1997,
consolidated sales were $310.8 million, up 13 percent from $275.2 million in the
same quarter last year. Sales rose 16 percent excluding unfavorable foreign
currency translation effects. The increase in sales was primarily attributable
to higher sales of metalworking products in North America and from higher sales
of industrial supplies sold by J&L Industrial Supply ("J&L") and by integrated
industrial supply programs ("Full Service Supply programs"), both operating
within JLK.
 
     Net income for the first quarter ended September 30, 1997, was $17.5
million, or $0.67 per share, as compared with net income of $15.2 million, or
$0.57 per share, in the same quarter last year. The results included expenses of
$5.2 million, or $0.12 per share, for the completion of the relocation and
related expenses incurred in connection with the construction of the new world
headquarters. Earnings benefited from higher sales of metalcutting and related
products in North America and Europe as well as from higher production levels
and productivity improvements related to its focused factory initiative of
rearranging manufacturing layout to improve productivity. This was partially
offset by unfavorable foreign currency translation effects.
 
     During the September 1997 quarter, sales in the North America Metalworking
market increased 7 percent from the previous year. Sales of metalcutting inserts
and toolholding devices in North America increased due to improved economic
conditions in the United States in most major end markets and from continued
emphasis on milling and drilling products. Additionally, sales of metalcutting
and toolholding devices sold through all sales channels in North America,
including sales through the industrial supply market, increased 11 percent.
 
     Sales in the Europe Metalworking market on a local currency basis increased
13 percent over the same quarter a year ago. Including unfavorable foreign
currency translation effects, sales in the Europe Metalworking market were flat.
Demand for metalworking products continued to show improvement during the
quarter in most key end markets as a result of improved market conditions in
Europe, principally in Germany. Sales in the European market have posted
double-digit order gains for four consecutive months.
 
     The Company recently acquired Rubig G.m.b.H. of Munich, Germany, Presto
Engineers Cutting Tools Limited of Sheffield, United Kingdom, and Car-Max Tool &
Cutter Sales, Inc. The companies had aggregate annual sales of approximately $46
million in 1996. The acquisitions were accounted for using the purchase method
of accounting. The consolidated financial statements include the operating
results of each business from the date of acquisition. The Company has also
recently entered into an agreement to acquire GRS Industrial Supply Company,
with annual sales of approximately $20 million in 1996.
 
     In the Asia Pacific Metalworking market, sales decreased slightly as
results were affected by weak economic conditions in Korea, Singapore and
Thailand. Excluding unfavorable foreign currency translation effects, sales in
the Asia Pacific Metalworking market increased 3 percent. Additionally,
effective August 1, 1997, the Company acquired 100 percent of Kennako Japan from
its joint venture partner, Kobe Steel.
 
     Sales in the industrial supply market rose 35.0 percent as a result of
increased sales through mail order, Full Service Supply programs and from
acquisitions. Excluding the acquisitions, sales increased approximately 24
percent. Sales increased because of four additional showrooms, from the
integration of new showroom locations from acquired companies, from further
penetration of existing customers, and from an expanded product offering of more
than 10,000 new stock keeping units ("SKUs") in J&L's 1998 master catalog issued
September 1, 1997.
 
     During the September 1997 quarter, sales in the mining and construction
market increased 10 percent from the previous year as a result of increased
domestic demand for highway construction tools. International sales of mining
and highway construction tools also improved as a result of strong market demand
in South Africa and China.

     COSTS AND EXPENSES.  As a percentage of sales, gross profit margin for the
September 1997 quarter was 42.5 percent as compared with 41.7 percent in the
prior year. The gross profit margin increased primarily as a result of
productivity improvements related in part to the focused factory initiative and
from higher production levels. This increase was partially offset by unfavorable
foreign currency translation effects.
 
     Operating expenses as a percentage of sales were 31.7 percent compared to
31.6 percent last year. Operating expenses increased 13 percent primarily
because of relocation and related costs incurred in connection with the
construction of the new world headquarters, which amounted to approximately $5.2
million during the first quarter. The project is now successfully completed.
Operating expenses also increased because of higher costs related to
acquisitions, and from the JLK showroom expansion program, including higher
direct mail costs and increased direct marketing costs in new territories in the
United States and in Europe.
 
     Interest expense for the September 1997 quarter was $1.2 million compared
to $2.6 million in the same quarter of a year ago. Interest expense decreased as
a result of lower debt balances as the Company used the proceeds received from
the initial public offering ("IPO") of approximately 4.9 million shares of
common stock of JLK.
 
     The effective tax rate for the September 1997 quarter was 39.0 percent
compared to an effective tax rate of 38.9 percent in the prior year.
 
FISCAL YEAR 1997 COMPARED TO FISCAL YEAR 1996
 
     OVERVIEW.  Net income for 1997 was $72.0 million, compared to $69.7 million
last year. While revenues and earnings rose to record highs, earnings were
affected by weakness in the European market, primarily in Germany, and from
negative effects of foreign currency translations due to the strength of the
U.S. dollar. Earnings for 1997 also were affected by additional costs related to
the J&L showroom expansion program, integration of new client-server information
systems and relocation and related costs associated with the construction of a
new world headquarters in Latrobe, Pennsylvania. Earnings in 1997 benefited from
slightly higher sales of metalworking products in North America and from higher
sales of metalworking products and industrial supplies sold to the Industrial
Supply market through mail order and Full Service Supply programs.

     SALES AND MARKETS.  Sales for the year ended June 30, 1997, were $1.2
billion, up 7 percent from $1.1 billion last year. Sales primarily increased in
1997 because of higher sales of metalworking products and industrial
 
                                      S-21
<PAGE>   223
 
supplies sold to the Industrial Supply market by J&L and by Full Service Supply
programs. The increase in sales was offset in part by lower sales of
metalworking products in Europe due to weak economic conditions, especially the
German market, and from negative foreign currency translation effects.
 
     Sales in the North America Metalworking market increased 3 percent over
1996, despite the transfer of small customer accounts to J&L, as a result of
improved economic conditions in the United States and from the continued
emphasis on milling and drilling products. Sales in Canada rose 15 percent
because of increased sales of metalworking products to aerospace and automotive
companies. Additionally, sales of traditional metalworking products sold through
all sales channels in North America, including sales through the Industrial
Supply market, increased 7 percent.
 
     Sales in the Europe Metalworking market decreased 7 percent. Demand for
metalworking products continued to be slow due to weak economic conditions in
Europe, primarily in the German market. Demand in Europe was weak for most of
1997 but began to show improvement during the fourth quarter of fiscal 1997.
Despite the economic situation in Europe, sales continued to post gains in the
United Kingdom and France. In the Asia Pacific Metalworking market, sales rose
16 percent as a result of increased demand in China, Japan and Taiwan, although
sales were affected by soft economic conditions in Korea and Thailand. Excluding
foreign currency translation effects, sales in the Europe Metalworking market
decreased 2 percent, while sales in the Asia Pacific Metalworking market
increased 21 percent.
 
     The Industrial Supply market was the major contributor to the overall sales
increase because of the continued growth of mail order and Full Service Supply
programs. Sales rose 28 percent primarily because of the expanded product
offering of over 20,000 new SKUs in the J&L 1997 master catalog, from the
addition of five new showrooms and from innovative marketing programs. Full
Service Supply programs increased, to a lesser extent, from the continued
ramp-up of existing Full Service Supply programs. Also contributing to the sales
increase was the acquisition of two industrial supply companies during the
fourth quarter of 1997. The acquired companies had annual sales of $36 million
in their latest fiscal year and will provide four additional showroom locations
in the Midwest. Excluding these acquisitions, the Industrial Supply market sales
increased 26 percent. At June 30, 1997, the Company operated a total of 28
showrooms, including six distribution centers in the United States and one in
the United Kingdom, and provided Full Service Supply programs to around 60
customers covering about 120 different facilities.
 
     Sales in the Mining and Construction market increased 6 percent from 1996
as a result of increased domestic and international demand for mining tools.
Highway construction tool sales were flat in the United States, while
international sales declined slightly as a result of weak economic conditions in
Europe.
 
     COSTS AND EXPENSES.  As a percentage of sales, gross profit margin for the
year ended June 30, 1997, was 42.2 percent, compared to 42.1 percent last year.
The gross profit margin improved slightly as a result of the positive effects of
productivity improvements related to the focused factory initiative. These
benefits were partially offset by a less favorable sales mix coupled with
unfavorable foreign currency translation effects.
 
     Operating expenses as a percentage of sales were 31 percent, compared to
30.4 percent last year, excluding the effects of the one-time restructuring
charge in fiscal 1996. Operating expenses increased primarily because of higher
costs related to the J&L showroom expansion program, including higher direct
mail costs and increased direct marketing in new territories in the United
States and in Europe. Operating expenses also increased from higher costs to
support new and existing Full Service Supply programs, from the integration of
new client-server information systems, from higher research and development
costs and from relocation and related costs of $4.7 million associated with the
construction of a new world headquarters.
 
     Interest expense decreased 8 percent because of lower average borrowings
coupled with slightly lower interest rates. The effective tax rate was 38.4
percent in 1997, compared to 38.6 percent in 1996. The decrease in the effective
tax rate resulted from additional tax benefits derived from international
operations.
 
FISCAL YEAR 1996 COMPARED TO FISCAL YEAR 1995
 
     OVERVIEW.  Net income for 1996 was $69.7 million, up 2 percent from $68.3
million in 1995. The 1996 results included a restructuring charge totaling $2.7
million ($0.06 per share) for the relocation of the North
 
                                      S-22
<PAGE>   224
 
America Metalworking Headquarters and for the closure of a manufacturing
facility in Canada. Excluding the restructuring charge, net income for 1996 was
up 5 percent.
 
     Earnings for 1996 increased because of the rapid growth in industrial
supply sales, primarily through mail order and Full Service Supply programs and
from slightly higher sales of metalcutting products in each of the three
metalworking markets. Earnings were affected by a less favorable sales mix and
lower production levels. Further, costs associated with the implementation of
new client-server information systems and focused factory programs reduced
pretax earnings by $10.4 million during 1996.
 
     SALES AND MARKETS.  Sales for the year ended June 30, 1996, were $1.1
billion, up 10 percent from $984 million in 1995. Sales increased in each of the
five markets over 1995. Sales increased in 1996 because of slightly higher sales
volumes and modest price increases.
 
     Sales in the North America Metalworking market were flat compared to the
prior year. Sales of metalcutting inserts and toolholding devices in the United
States were flat, as sales growth was affected by weak economic conditions.
Sales of metalworking products in Canada increased 11 percent because of
increased demand.
 
     In the Europe Metalworking market, sales increased 7 percent because of
higher sales volumes. Demand for metalworking products was slow in Germany,
while sales grew at a faster pace in the United Kingdom and France. Demand in
Europe was stronger in the first half of the fiscal year but slowed as the year
progressed. In the Asia Pacific Metalworking market, sales rose 11 percent as a
result of increased demand. Sales also increased because, effective July 1,
1995, Kennametal began to consolidate its majority-owned subsidiaries in China
and Japan. Excluding foreign currency translation effects, sales in the Europe
and Asia Pacific Metalworking markets increased 6 and 7 percent, respectively.
 
     The Industrial Supply market accounted for the largest percentage sales
gain because of the rapid growth of mail order and Full Service Supply programs.
Sales rose 28 percent as a result of aggressive marketing programs, the
successful geographic showroom expansion program at J&L and new and existing
Full Service Supply programs with large customers. During fiscal 1996, J&L
opened seven showroom locations and at the end of fiscal 1996 operated a total
of 18 showrooms in the United States and one location in the United Kingdom.
Full Service Supply added 18 new contracts, bringing the total number to
slightly more than 50 contracts covering more than 100 plant locations in 1996.
Also, during June 1996, the Company began transferring small customer accounts
from the North America Metalworking market to J&L to provide added customer
service and to further leverage J&L's full complement of metalcutting supplies.
 
     Sales in the Mining and Construction market increased 9 percent over 1995
as a result of strong domestic demand for both mining and highway construction
tools. International sales rose only slightly because of increased competition.
 
     COSTS AND EXPENSES.  As a percentage of sales, gross profit margin for the
year ended June 30, 1996, was 42.1 percent, compared to 43.0 percent in 1995.
The gross profit margin benefited from higher sales volumes and modest price
increases. These benefits were offset by a less favorable sales mix, slightly
higher raw material costs, costs associated with the implementation of focused
factory programs and reduced manufacturing efficiencies because of lower
production levels.
 
     Operating expenses as a percentage of sales were 30.4 percent, compared to
29.9 percent in 1995. Operating expenses increased 12 percent primarily because
of costs related to the implementation of new client-server information systems,
costs necessary to support the higher sales levels, and marketing and showroom
expansion programs at J&L. Results of operations also included a restructuring
charge related to the consolidation of the North America Metalworking
headquarters from Raleigh, North Carolina, to Latrobe, Pennsylvania, and the
closure of a manufacturing facility in Canada. These pretax items were recorded
during the fourth quarter of fiscal 1996 and amounted to $2.7 million.
 
     Interest expense decreased 12 percent because of lower average borrowings
and slightly lower interest rates. The effective tax rate was 38.6 percent in
1996, compared to 39.7 percent in 1995. The decrease in the effective tax rate
resulted from additional tax benefits derived from international operations.

     RESTRUCTURING CHARGE.  During the fourth quarter of fiscal 1996, the
Company recorded a pretax charge of $2.7 million to relocate its North America
Metalworking headquarters from Raleigh, North Carolina, to Latrobe,
Pennsylvania, and to close a manufacturing facility in Canada. The relocation
was made to globalize key functions and to provide a more efficient corporate
structure. As a result, a pretax charge of $2.7 million was recorded to cover
the related one-time costs of employee separation arrangements and early
retirements. In connection with the relocation, the Company is constructing a
new world headquarters building estimated to cost $20 million.
 
     Certain costs resulting from the relocation of employees, hiring and
training new employees, and other costs resulting from the temporary duplication
of certain operations were not included in the one-time charge and will be
included in operating expenses as incurred. The costs related to these items
were estimated to be $9 million pretax and will be incurred during fiscal 1997
and 1998.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     On October 10, 1997, Kennametal and Acquisition Corp. entered into the
Merger Agreement with Greenfield pursuant to which Acquisition Corp. purchased
at $38 per share on November 17, 1997 approximately 16,179,976 shares (98
percent of the outstanding) of Greenfield's common stock. The Merger occurred on
November 18, 1997 and Greenfield became a wholly-owned subsidiary of Kennametal
on that date. The total purchase price for the acquisition of Greenfield
(including estimated transaction costs and assumed Greenfield debt and
convertible redeemable preferred securities of approximately $320 million) is
estimated to be $1.0 billion.
 
     In connection with the acquisition of Greenfield, the Company, on November
17, 1997, entered into the New Bank Credit Facility. As of November 18, 1997,
the Company had borrowed $500 million in term loans and approximately $300
million in revolving credit loans under the New Bank Credit Facility. The
proceeds from the loans were principally used to pay for the shares of common
stock of Greenfield purchased in the Tender Offer and the Merger, to pay
transaction costs, to refinance certain indebtedness of Greenfield and to
refinance certain indebtedness of the Company. Subject to certain conditions,
the New Bank Credit Facility permits revolving credit loans of up to $900
million for working capital requirements, capital expenditures, and general
corporate purposes. The New Bank Credit Facility initially will be secured by
all of the stock of certain of Kennametal's significant domestic subsidiaries,
by guarantees of certain of such subsidiaries and by 65 percent of the stock of
Kennametal's significant foreign subsidiaries. The New Bank Credit Facility
contains various restrictive covenants and affirmative covenants requiring the
maintenance of certain financial ratios. The term loans under the New Bank
Credit Facility are subject to mandatory prepayments commencing on November 30,
1998 and all loans mature on August 31, 2002. Proceeds from the Offerings and
the FELINE PRIDE Offering will be used to prepay term loans under the New Bank
Credit Facility.
 
     Kennametal's cash flow from operations is the primary source of financing
for capital expenditures and internal growth. The Company and its subsidiaries
generally obtain local financing through credit lines with commercial banks.
 
     During 1997, the Company generated $99.9 million in cash from operations.
Cash provided by operations increased from 1996 primarily because of lower
working capital requirements and slightly higher net income. Capital
expenditures, totaling $73.8 million, were made to construct a new world
headquarters in Latrobe, Pennsylvania, and a manufacturing facility in China,
for new client-server information systems and to upgrade machinery and
equipment. Additionally, the Company paid $17.5 million of cash dividends and
paid $19 million to acquire five small companies throughout 1997. The effects of
the acquisitions were not significant to the Company. During the quarter ended
September 30, 1997, the Company generated $40.6 million in cash from operations.
The increase in cash provided by operations resulted primarily from higher net
income and slightly lower incremental working capital requirements. Net cash
used in investing activities during the quarter ended September 30, 1997 was
$32.4 million. The increase in net cash used in investing activities resulted
from higher capital expenditures and from the acquisition of Rubig G.m.b.H. and
the remaining interest in Kennako Japan from its joint venture partner Kobe
Steel.

     On January 31, 1997, the Company initiated a stock repurchase program to
repurchase from time to time up to a total of 1.6 million shares of its
outstanding capital stock. During the year ended June 30, 1997, the Company
repurchased approximately 781,000 shares of its Common Stock at a total cost of
approximately $28.7 million. The repurchases were made in the open market or in
negotiated or other permissible transactions. The repurchase of Common Stock was
financed principally by cash from operations and short-term borrowings.
 
     On July 2, 1997, an IPO of approximately 4.9 million shares of common stock
of JLK at a price of $20 per share was consummated. JLK operates the industrial
supply operations consisting of the Company's wholly owned J&L subsidiary and
its Full Service Supply programs. The net proceeds from the offering were
approximately $90 million and represented the sale of approximately 20 percent
of JLK's common stock. The net proceeds were used by JLK to repay $20 million of
indebtedness related to a dividend to the Company and $20 million related to
intercompany obligations to the Company. The Company used these proceeds to
repay short-term debt. In connection with the IPO, the remaining net proceeds
were loaned to the Company, under an intercompany debt/investment and cash
management agreement at a fluctuating rate of interest equal to the Company's
short-term borrowing costs. The Company will maintain unused lines of credit to
enable it to repay any portion of the borrowed funds as the amounts are due on
demand by JLK. The Company owns approximately 80 percent of the outstanding
common stock of JLK and intends to retain a majority of both the economic and
voting interests of JLK.
 
     During 1996, the Company generated $85 million in cash from operations,
which was used primarily to finance $58 million of capital expenditures and to
pay $16 million of cash dividends. Capital expenditures were made to modernize
facilities, to upgrade machinery and equipment, and to acquire new information
systems. In January 1996, the Company announced plans to build a $20 million
facility in Shanghai, China to manufacture cemented carbide metalcutting tools.
Pilot production commenced in the second quarter of fiscal 1998 with full
production beginning in the third quarter of fiscal 1998.
 
     During 1995, the Company generated $57 million in cash from operations,
which was used primarily to finance $43 million of capital expenditures and to
pay $16 million of cash dividends. Capital expenditures were made to modernize
facilities, to upgrade machinery and equipment and to acquire new information
systems.
 
     Capital expenditures for fiscal 1998 (excluding) Greenfield are estimated
to be $70-$80 million of which $16.7 million has been spent through September
30, 1997, and will be used primarily to complete the construction of a new world
headquarters in Latrobe, Pennsylvania and a manufacturing facility in China, to
acquire additional client-server information systems, to construct or acquire a
new Midwest distribution center and to upgrade machinery and equipment.
 
FINANCIAL CONDITION
 
     Kennametal's financial condition continues to remain strong. Total assets
were $869 million in 1997, up 9 percent from $799 million in 1996. Net working
capital was $176 million, down 19 percent from the previous year. The ratio of
current assets to current liabilities was 1.6 in 1997, compared with 2.0 in
1996. Total assets were $920 million at September 30, 1997, up 6 percent from
$869 million at June 30, 1997. Net working capital was $258 million, up 47
percent from $176 million from the previous quarter and the ratio of current
assets to current liabilities was 2.1 as of September 30, 1997 and 1.6 as of
June 30, 1997.
 
     Accounts receivable increased 6 percent to $201 million because of
increased sales and from the effects of acquisitions. Inventories rose slightly
to $210 million due to the growth of sales to the Industrial Supply market, the
effects of acquisitions, offset by the Company's inventory reduction efforts of
manufactured products. Inventory turnover was 3.2 in 1997 and 3.0 in 1996. The
Company will continue to focus on ways to improve inventory turnover and overall
asset utilization.
 
     Total debt (including capital lease obligations) increased 33 percent to
$174 million in 1997. In 1997, total debt increased principally because of the
stock repurchase program and increased capital expenditures. The ratio of total
debt to total capital (i.e., total debt divided by the sum of total debt,
minority interest and shareholders' equity) was 27 percent in 1997 as compared
with 23 percent in 1996. Total debt decreased 42% to $101 million and the
Company's debt-to-capital ratio was 15 percent at September 30, 1997. Total debt
decreased as a result of
 
                                      S-25
<PAGE>   227
 
the application of net proceeds of $90 million received from the IPO of
approximately 4.9 million shares of common stock of JLK.
 
     After the acquisition of Greenfield, the Offerings and the FELINE PRIDES
Offering and the application of the net proceeds therefrom, total debt will
increase to approximately $668 million and the debt-to-capital ratio will
increase to approximately 40 percent. To maintain financial flexibility and to
optimize the cost of capital, Kennametal's financial objective, over the long
term, is to maintain a total debt-to-capital ratio of not more than 40 percent.
Cash from operations and the Company's debt capacity are expected to continue to
be sufficient to fund capital expenditures, dividend payments, stock
repurchases, acquisitions and operating requirements.
 
ENVIRONMENTAL MATTERS
 
     The Company has been involved in various environmental cleanup and
remediation activities at several of its manufacturing facilities. In addition,
the Company has been named as a potentially responsible party at several
Superfund sites in the United States. However, management believes that, based
on its evaluations and discussions with outside counsel and independent
consultants, that the ultimate resolution of these environmental matters will
not have a material adverse effect on the results of operations, financial
position or cash flows of the Company. See Note 14 to the consolidated financial
statements.
 
NEW ACCOUNTING STANDARDS
 
     The Financial Accounting Standards Board ("FASB") recently issued Statement
of Financial Accounting Standards ("SFAS") No. 128, "Earnings Per Share" and
SFAS No. 129, "Disclosure of Information about Capital Structures." SFAS No. 128
was issued in February 1997 and is effective for periods ending after December
15, 1997. This statement, upon adoption, will require all prior year earnings
per share ("EPS") data to be restated to conform to the provisions of the
statement. This statement's objective is to simplify the computations of EPS and
to make the U.S. standard for EPS computations more compatible with that of the
International Accounting Standards Committee. The Company will adopt SFAS No.
128 in fiscal 1998 and does not anticipate that the statement will have a
significant impact on its reported EPS.
 
     SFAS No. 129 was issued in February 1997 and is effective for periods
ending after December 15, 1997. This statement, upon adoption, will require all
companies to provide specific disclosure regarding their capital structure. SFAS
No. 129 will specify the disclosure for all companies, including descriptions of
their capital structure and the contractual rights of the holders of such
securities. The Company will adopt SFAS No. 129 in fiscal 1998 and does not
anticipate that the statement will have a significant impact on its disclosures.
 
     Additionally, in June 1997, the FASB issued SFAS No. 130, "Reporting
Comprehensive Income" (SFAS No. 130) and SFAS No. 131, "Disclosures About
Segments of an Enterprise and Related Information" (SFAS No. 131). SFAS No. 130
is effective for years ending after December 15, 1997. SFAS No. 130 establishes
standards for reporting and display of comprehensive income and its components
in a full set of general-purpose financial statements. The Company will adopt
SFAS No. 130 in fiscal 1998 and does not anticipate that the statement will have
a significant impact on its disclosures.
 
     SFAS No. 131 introduces a new model for segment reporting called the
"management approach." The management approach is based on the way the chief
operating decision-maker organizes segments within a company for making
operating decisions and assessing performance. SFAS No. 131 is effective for
fiscal years beginning after December 15, 1997. The Company is in the process of
evaluating the effect of applying this statement.
 
EFFECTS OF INFLATION
 
     Despite modest inflation in recent years, rising costs continue to affect
the Company's operations throughout the world. Kennametal strives to minimize
the effects of inflation through cost containment, productivity improvements and
price increases under highly competitive conditions.

                                    BUSINESS
 
     The Company is a vertically integrated global manufacturer, marketer and
distributor of a broad range of consumable tools, supplies and services for the
metalworking, mining and highway construction industries. Kennametal specializes
in developing and manufacturing tools utilizing tungsten carbide powder
metallurgy for the three primary metalcutting methods--turning, milling and
drilling. In addition, through JLK, the Company markets and distributes a broad
line of consumable metalcutting tools, as well as abrasives, machine tool
accessories, hand tools, measuring equipment and other industrial supplies used
in the metalworking industry. The Company is a recognized leader in turning and
milling consumable metalcutting tools and believes it is the largest North
American and the second largest global provider of consumable metalcutting tools
and supplies. Leveraging its expertise in tungsten carbide powder metallurgy,
the Company has developed innovative consumable tools for the mining and
construction industries and believes it is the largest global manufacturer,
marketer and distributor of such tools to these markets.
 
     In November 1997, the Company acquired Greenfield Industries, Inc., the
leading North American manufacturer of drilling and other rotary high-speed
steel consumable metalcutting tools for the metalworking industry. Kennametal
believes that Greenfield's operations strongly complement its core businesses
and that the acquisition of Greenfield, in addition to providing the Company
with opportunities for substantial cost savings, offers significant strategic
benefits, including: (i) providing an important new channel of traditional
industrial distributors through which to sell the Company's products; (ii)
expanding and enhancing the Company's line of drilling products; (iii) allowing
the Company to diversify into new markets such as certain wear products by
leveraging its material science expertise in tungsten carbide powder metallurgy
and (iv) providing the opportunity to introduce and sell each company's products
into the markets served by the other company.
 
     End users of the Company's metalworking products include manufacturers and
suppliers in the aerospace, automotive, construction and farm machinery,
railroad equipment, power generation and transmission equipment, home appliance,
electrical equipment, and oil field services and gas exploration industries. The
Company markets its products through: a technically skilled direct sales force;
JLK's catalogs, showrooms and other direct marketing efforts; JLK's integrated
industrial supply programs; and, with the acquisition of Greenfield, a network
of traditional industrial distributors. This multi-channel product marketing
approach enables the Company to meet the varying needs of metalworking customers
of all sizes which range from same-day ordering and rapid delivery of products
to outsourcing the entire procurement and inventory management process for
metalworking and related products. The Company estimates there are approximately
250,000 metalworking industrial sites in the United States. The Company's
multi-channel distribution network, comprehensive product offering and global
presence allow customers of all sizes the advantage of a single source of supply
for most metalworking needs.
 
     The Company believes five significant trends are currently impacting the
metalworking industry: (i) consolidation of fragmented distribution channels as
customers seek a single source of supply for their metalworking needs; (ii)
increasing demand from large customers to outsource procurement and inventory
management processes through integrated supply programs; (iii) growing demand
for suppliers that can provide a complete selection of tools, supplies and
services globally; (iv) demand for world class capabilities including customer
service, technical application support and information and product technology
while, at the same time, maintaining or reducing costs; and (v) continuing
advances in customers' metalworking manufacturing technology requiring more
technically advanced tools. These factors are resulting in a restructuring and
consolidation in the metalworking industry as tooling manufacturers and
distributors are forced to either become more competitive or seek stronger
partners. The Company's business strategy is designed to capitalize on these and
other trends.
 
     The address of the Company's principal executive office is Route 981 South
at Westmoreland County Airport, Latrobe, Pennsylvania 15650 and its telephone
number is (412) 539-5000.
 
BUSINESS STRATEGY
 
     The Company's objective is to become the supplier of first choice of
consumable tools, related supplies, and services to the worldwide metalworking
industry and to other industries which can benefit from tungsten carbide
products. The Company believes its market-leadership position results from
successful implementation of its business strategy, the major elements of which
include:
 
                                      S-27
<PAGE>   229
 
     - Expanding Customer Base Through Multi-Channel Distribution.  The Company
      seeks to access potential customers through all primary distribution
      channels. The Company serves its traditional base of large and
      medium-sized metalworking customers through a direct sales force. JLK
      direct markets a broad range of tiered ("good," "better" and "best")
      metalworking consumables and other related products targeted at small and
      medium-sized metalworking customers and offers integrated supply programs
      targeted at large industrial metalworking customers. The acquisition of
      Greenfield, which sells its consumable tools, related products and
      services through a network of more than 2,500 traditional industrial
      distributors, provides Kennametal with access to approximately 50% of the
      North American metalworking market.
 
     - Providing Most Complete Product Offering.  The Company seeks to provide
      the most complete and comprehensive product offering in the metalworking
      industry. As a result of various acquisitions and internal development,
      the Company markets and distributes what it believes is one of the
      broadest lines of tools and services typically used by metalworking
      customers. The recent acquisition of Greenfield and its consumable
      high-speed steel rotary cutting tools and related products provides the
      Company with the capability to manufacture all of the major consumable
      tools needed by customers in their metalcutting manufacturing processes.
 
     - Expanding Strong Global Presence.  Kennametal is committed to growing its
      global presence as demonstrated by its position as the second largest
      provider of tools to the European metalworking industry, the world's
      largest metalworking market, and its plans to expand its presence in the
      Asia Pacific region. The Company recently completed construction of a
      cutting tool manufacturing facility in Shanghai, China for a total
      investment of about $20 million, and has increased to 100% its ownership
      interest in a sales and marketing subsidiary in Japan. The Company also
      has targeted marketing efforts in Eastern Europe and Russia and other
      developing countries.
 
     - Providing Superior Customer Service, Product Availability, and Technical
      Support.  The Company's skills in rapidly filling orders, maintaining high
      levels of product availability and providing technical product application
      support are vital to the ability of its metalworking customers to meet
      their production and delivery schedules in a cost-effective manner.
      Kennametal's sophisticated order entry and inventory management systems
      enable the Company to ship more than 90 percent of its products from
      stock. In addition, the Company's technically skilled direct sales force
      of more than 700 persons provide on-site product selection and application
      support to enable customers to optimize their metalcutting processes. The
      addition of Greenfield's more than 70 technical specialists broadens the
      Company's technical support capability into high-speed steel drilling
      applications.
 
     - Maintaining Leadership in Product Innovation.  As a result of its
      commitment to research and development, the Company has brought to market
      during the past few years a number of new or improved metalcutting
      products. The exacting requirements of modern high-precision metalcutting,
      along with advances in manufacturing technology, exacting manufacturing
      specifications, and new workpiece materials, are driving the demand for
      new and improved consumable tools and systems capable of achieving
      superior technical performance with high and uniform quality. The Company
      believes that its reputation for supplying high quality and
      technologically innovative consumable metalcutting tools and supplies to
      the metalworking industry has been very significant in achieving its
      market position.
 
     - Leveraging Use of Information Technology.  The Company's decision to
      invest nearly $40 million in a business information system utilizing SAP
      R-3 software demonstrates its commitment to the use of information
      technology. This system, which is expected to be fully operational in
      fiscal 1999, will link sales, distribution, manufacturing, purchasing and
      accounting activities at all major sites throughout Kennametal and is
      designed to enhance customer service, operational effectiveness and
      management decision-making.
 
     In addition to the above business strategies, the Company seeks to continue
to improve operating efficiencies as well as to pursue selected acquisitions
that enhance its distribution channels, complement its existing product
offerings and strengthen its geographic presence.

BUSINESS SEGMENT AND MARKETS
 
     The Company operates predominantly as a tooling supplier specializing in
powder metallurgy, which represents a single business segment. While many of the
Company's products are similar in composition, sales are classified into three
markets: metalworking, industrial supply, and mining and construction.
 
     METALWORKING MARKETS.  Kennametal markets, manufactures and distributes a
full line of products and services for the metalworking industry. The Company
provides metalcutting tools to manufacturing companies in a wide range of
industries throughout the world.
 
     A Kennametal tooling system usually consists of a steel toolholder and an
indexable cutting tool called an insert. During a metalworking operation, the
toolholder is positioned in a machine tool that provides the turning power.
While the workpiece or toolholder is rapidly rotating, the cutting tool insert
contacts the workpiece and cuts or shapes the workpiece. The cutting tool insert
is consumed during use and must be replaced periodically. Metalcutting
operations include turning, boring, threading, grooving, milling and drilling.
The Company also makes wear-resistant parts for use in abrasive environments and
specialty applications.
 
     INDUSTRIAL SUPPLY MARKET.  Kennametal distributes a full line of industrial
supplies to the metalworking industry principally through JLK. These products
include cutting tools, abrasives, precision measuring devices, power tools and
hand tools, machine tool accessories and, to a lesser extent, some maintenance,
repair and operating supplies. The majority of industrial supplies distributed
by the Company are purchased from other manufacturers, although the industrial
supply product offering does include Kennametal-manufactured items.
 
     MINING AND CONSTRUCTION MARKET.  Mining and construction cutting tools are
fabricated from steel parts and tipped with cemented carbide. Mining tools, used
primarily in the coal industry, include longwall shearer and continuous miner
drums, blocks, bits, pinning rods, augers and a wide range of mining tool
accessories. The Company also supplies compacts for mining, quarrying, water
well drilling and oil and gas exploration. Construction cutting tools include
carbide-tipped bits for ditching, trenching and road planing, grader blades for
site preparation and routine roadbed control, and snowplow blades and shoes for
winter road plowing.
 
     The Company also makes proprietary metallurgical powders for use as a basic
material in many of its metalworking, mining and construction products. In
addition, the Company produces a variety of metallurgical powders and related
materials for specialized markets. These products include intermediate carbide
powders, hardfacing materials and matrix powders that are sold to manufacturers
of cemented carbide products, oil and gas drilling equipment and diamond drill
bits.
 
     INTERNATIONAL OPERATIONS.  The Company's principal international operations
are conducted in Western Europe and Canada. In addition, the Company has joint
ventures in India, Italy, Poland and Russia, manufacturing and sales
subsidiaries in Asia Pacific and sales agents and distributors in eastern Europe
and other areas of the world.
 
     The Company's international operations are subject to the usual risks of
doing business in those countries, including currency fluctuations and changes
in social, political and economic environments. In management's opinion, the
Company's business is not materially dependent upon any one international
location involving significant risk.
 
MARKETING AND DISTRIBUTION
 
     The Company's products are sold through three distinct channels: a direct
sales force, Full Service Supply programs, and retail showrooms and mail-order
catalogs. The Company's manufactured products are sold to end users primarily
through a direct sales force. Service engineers and technicians directly assist
customers with product design, selection and application. In addition,
Kennametal-manufactured products, together with a broad range of purchased
products, are sold through Full Service Supply programs and retail showrooms and
mail-order catalogs. The Company also uses independent distributors and sales
agents in the United States and certain international markets.

GREENFIELD
 
     GENERAL.  Greenfield is a leading manufacturer of consumable cutting tools
and related products used primarily in industrial applications and is the
largest North American producer of expendable rotary cutting tools used to cut
metal and other industrial materials. Greenfield's products are sold in six
principal markets: industrial, electronics, energy and construction, engineered
products, consumer and marine. Greenfield offers products made from high-speed
steel and tungsten carbide materials; and each accounts for approximately half
of Greenfield's revenues. In addition, Greenfield manufactures and markets a
line of marine products.
 
     MARKETS AND PRODUCTS.  Greenfield manufactures and markets expendable
cutting tools and carbide products to the industrial, electronics, energy and
construction, engineered products, and consumer markets. Greenfield manufactures
a wide variety of cutting tools. High-speed steel is the predominant material
for rotary cutting tools, offering high performance in a broad range of
applications. Tungsten carbide materials are costlier and more durable and are
preferred in certain applications. Greenfield also manufactures and markets a
line of marine products. Greenfield's brand names enjoy a high degree of
recognition in their respective markets. Greenfield also supplies a number of
industrial and consumer private label customers with its products, including
Sears' line of Craftsman(R) drill bits.
 
     Greenfield is the largest producer in North America of rotary cutting tools
for industrial applications. Products sold in the industrial market include
rotary cutting tools and related products such as drills, reamers, taps, end
mills, burrs, routers, counterbores and countersinks. Greenfield also
manufactures and markets an extensive line of hardware products, primarily
stationary and portable power tool accessories for use in the industrial and
consumer markets. In 1996, the industrial market accounted for approximately 51%
of Greenfield's consolidated net sales.
 
     Greenfield manufactures and markets small diameter circuit board drills for
the electronics market. Greenfield believes that it is one of the largest
worldwide manufacturers of circuit board drills and routers. In 1996, the
electronics market accounted for approximately 12% of Greenfield's consolidated
net sales.
 
     Greenfield believes that it is the largest independent supplier of oilfield
compacts in the world. Compacts are the cutting edges of oil well drilling bits,
which are commonly referred to as "rock bits." Greenfield's compacts are used
both for oil and natural gas drilling. Natural gas reserves tend to be found
deeper than oil, thereby increasing the utilization of rock bits. Greenfield is
a significant producer of tungsten carbide-tipped mining bits for the United
States coal mining industry and manufactures mining bit accessories and
carbide-tipped bits used in highway road resurfacing. In 1996, the energy and
construction market accounted for approximately 12% of Greenfield's consolidated
net sales.
 
     Greenfield is an on-demand producer of custom-made tungsten carbide preform
wear parts for use in the tool and die industry including stamping dies, powder
metal tooling, container and impact tooling, seal rings, extruded rods, wear
parts and steel processing parts. Greenfield also manufactures tungsten carbide
balls used in rotary equipment such as pumps and mixers and seats which are
components in the check valves used in oil producing pumps, tungsten carbide
trim parts used in oil field chokes, mechanical face seals and ceramic-based
wear parts. In 1996, the engineered products market accounted for approximately
13% of Greenfield's consolidated net sales.
 
     Greenfield is an active supplier of consumer drill bits, saws, hand tools
and other products to the do-it-yourself market, which includes Sears, Home
Depot and other major retailers and includes products sold under private label
brands such as the Sears Craftsman(R) drill line, which Greenfield has supplied
for more than 65 years. In 1996, the consumer market accounted for approximately
7% of Greenfield's consolidated net sales.
 
                                      S-30
<PAGE>   232
 
     Greenfield also manufactures a line of marine products. Greenfield's marine
products include submersible pumps, activating switches, magnetic compasses,
DC-powered winches and various electronic instruments and gauges. In 1996, the
marine market accounted for approximately 5% of Greenfield's consolidated net
sales.
 
     MARKETING AND DISTRIBUTION.  Greenfield's cutting tool products are sold
primarily through selected distributors supported by Greenfield's technical
sales personnel. In addition to distributors, Greenfield sells cutting tool
products as well as other products directly to private label, catalog, large
industrial and other customers having special technical or other requirements.
Generally, Greenfield's major brands are represented by distinct sales forces.
Greenfield's sales force numbers approximately 150 and sells to over 2,500
independent distributors in North America and worldwide.
 
COMPETITION
 
     Kennametal is one of the world's leading producers of cemented carbide
tools and maintains a strong competitive position, especially in North America
and Europe. There is active competition in the sale of all products made by the
Company, with approximately 30 companies engaged in the cemented carbide
business in the United States and many more outside the United States. Several
competitors are divisions of larger corporations. In addition, several hundred
fabricators and toolmakers, many of whom operate out of relatively small shops,
produce tools similar to those made by the Company and buy the cemented carbide
components for such tools from cemented carbide producers, including the
Company. Major competition exists from both U.S.-based and international-based
concerns. In addition, the Company competes with thousands of industrial supply
distributors.
 
     The purchase price of consumable cutting tools is relatively small compared
to the customer's significant investment in production equipment, control
systems, work piece materials and a trained work force. However, use of the
customer's equipment and systems can be significantly impaired if consumable
cutting tools are of inconsistent quality, fail to meet technical
specifications, or are not readily available. The Company therefore believes
that its competitive strengths rest on the consistently high quality of its
products, state-of-the-art manufacturing capabilities, customer service,
multiple distribution channels, global presence, and its ability to develop new
and improved systems responsive to its customer's needs. These factors
frequently permit the Company to sell many of its products based on their value
added to the customer, rather than strictly on price.
 
SEASONALITY
 
     Seasonal variations do not have a major effect on the Company's and
Greenfield's business. However, to varying degrees, traditional summer vacation
shutdowns of metalworking customers' plants and holiday shutdowns often affect
the Company's first and second fiscal quarters and Greenfield's third and fourth
fiscal quarters.
 
RESEARCH AND DEVELOPMENT
 
     The Company is involved in research and development of new products and
processes. Research and development expenses totaled $18.7 million, $20.6
million and $24.1 million in 1995, 1996 and 1997, respectively. Additionally,
certain costs associated with improving manufacturing processes are included in
cost of goods sold. The Company holds a number of patents and licenses which, in
the aggregate, are not material to the operation of the business.
 
     The Company has brought a number of new products to market during the past
few years. These include metalcutting inserts that incorporate innovative tool
geometries or compositions for improved chip control and productivity. These new
compositions include KC994M* multi-coated metalcutting inserts for milling
applications, KC9010* and KC9025* multi-coated metalcutting inserts for turning
applications, Kyon 3500* ceramic metalcutting inserts for machining cast irons,
and KCD25* diamond-coated metalcutting inserts for machining aluminum alloys and
other nonferrous materials.

EMPLOYEES
 
     The Company employed approximately 7,500 persons at June 30, 1997, of which
4,700 were located in the United States and 2,800 in other parts of the world,
principally Europe and Asia Pacific. Approximately 1,100 employees were
represented by labor unions, of which 170 were hourly-rated employees located at
plants in the Latrobe, Pennsylvania area. The remaining 930 employees
represented by labor unions were employed at seven plants located outside of the
United States. The Company has not experienced any work stoppages in the last
five years and considers its labor relations to be generally good.
 
     At December 31, 1996, Greenfield had approximately 5,000 employees
worldwide. Approximately 1,000 employees at eight of Greenfield's facilities
were covered under collective bargaining agreements which expire through June
2002. Greenfield has not experienced any work stoppages in the last five years
and considers its relations with employees to be good.
 
REGULATION
 
     Compliance with government laws and regulations pertaining to the discharge
of materials or pollutants into the environment or otherwise relating to the
protection of the environment did not have a material effect on the Company's
capital expenditures, earnings or competitive position for fiscal 1997, nor is
such compliance expected to have a material effect in the future.
 
     The Company has been involved in various environmental cleanup and
remediation activities at several of its manufacturing facilities. In addition,
the Company has been named as a potentially responsible party at several
Superfund sites in the United States. However, in management's opinion, based on
its evaluations and discussions with outside counsel and independent
consultants, the ultimate resolution of these environmental matters will not
have a material adverse effect on the results of operations, financial position
or cash flows of the Company.
 
     The Company maintains a Corporate Environmental, Health and Safety ("EH&S")
Department as well as an EH&S Policy Committee to ensure compliance with
environmental regulations and to monitor and oversee remediation activities. In
addition, the Company has established an EH&S administrator at each of its
domestic manufacturing facilities. The Company's financial management team
periodically meets with members of the Corporate EH&S Department and the
Corporate Legal Department to review and evaluate the status of environmental
projects and contingencies. On a quarterly and annual basis, management
establishes or adjusts financial provisions and reserves for environmental
contingencies in accordance with Statement of Financial Accounting Standards No.
5, "Accounting for Contingencies."
 
     Greenfield regularly conducts an environmental assessment consistent with
recognized standards of due diligence on properties and businesses which it
acquires. To date, these assessments have not identified contamination, which
would result in material expenses, in respect of acquired properties that would
be reasonably likely to result in a material adverse effect on Greenfield's
business, results of operations or financial condition. As a general rule,
Greenfield intends to use such assessments as part of the evaluation of proposed
acquisitions. However, there can be no assurance that environmental assessments
have identified, or will in the future identify, all potential liabilities
relating to Greenfield's properties and businesses, that any indemnification
agreements that can be negotiated will cover all potential liabilities, or that
changes in cleanup requirements or subsequent events at Greenfield's properties
or at off-site locations will not result in significant costs to Greenfield.

(a) In January 1996, the Company announced plans to construct a $20 million
    facility in Shanghai, China, to manufacture cemented carbide metalcutting
    tools. Operations began in the second quarter of fiscal 1998.
 
     The Company also has a network of warehouses and customer service centers
located throughout North America, Western Europe, Asia and Australia, a
significant portion of which are leased. The majority of the Company's research
and development efforts are conducted in a corporate technology center located
adjacent to world headquarters in Latrobe, Pennsylvania and in Furth, Germany.
 
     All significant properties are used in the Company's dominant business of
powder metallurgy, tools, tooling systems and supplies. The Company's production
capacity is adequate for its present needs. The Company believes that its
properties have been adequately maintained, are generally in good condition and
are suitable for the Company's business as presently conducted.
 
     Greenfield's headquarters are located in Augusta, Georgia. Greenfield owns
significant manufacturing facilities in Arkansas, Georgia, Indiana,
Massachusetts, Michigan, North Carolina, Ohio, Pennsylvania, South Carolina and
Virginia, and leases significant facilities in Illinois, Massachusetts,
Missouri, Vermont and Wisconsin. Greenfield also maintains, through ownership or
leases, smaller manufacturing, office, warehouse and research facilities, as
well as property held for sale, in eight other states and seven other countries.
In the event of a cancellation or termination of a lease relating to any of
Greenfield's leased properties, Greenfield anticipates no difficulty in
connection with leasing alternate space at reasonable rates.
 
LEGAL MATTERS
 
     There are no material legal proceedings pending against the Company.

                          DESCRIPTION OF COMMON STOCK
 
     The following brief description of the Company's capital stock does not
purport to be complete and is subject in all respects to applicable Pennsylvania
law and to the provisions of the Company's Amended and Restated Articles of
Incorporation (the "Restated Articles") and its Amended and Restated By-Laws
(the "Restated By-Laws"), copies of which have been filed with the Commission.
 
COMMON STOCK
 
     The Company has authorized 70,000,000 shares of Capital Stock, par value
$1.25 per share ("Common Stock"). As of October 31, 1997, there were 26,264,454
shares of Common Stock outstanding. Holders of Common Stock are entitled to such
dividends as may be declared by the Board of Directors out of funds legally
available therefor after payment of dividends on any outstanding Preferred Stock
and are entitled to one vote for each share of Common Stock held by them with
respect to all matters upon which they are entitled to vote.
 
PREFERRED STOCK
 
     The Company has authorized 5,000,000 shares of Class A Preferred Stock, no
par value per share (the "Preferred Stock"). At present there are no shares of
Preferred Stock outstanding. The Board of Directors of the Company, without
further action by the stockholders, is authorized to designate and issue in
series Preferred Stock and to fix as to any series the dividend rate, redemption
prices, preferences on dissolution, the terms of any sinking fund, conversion
rights, voting rights, and any other preferences or special rights and
qualifications. The Board of Directors of the Company has authorized 200,000
shares of Series One Preferred Stock for use in the Rights Plan. See "Rights
Plan".
 
     Any Preferred Stock so issued may rank senior to the Common Stock with
respect to the payment of dividends or amounts upon liquidation, dissolution or
winding up, or both. In addition, any such shares of Preferred Stock may have
class or series voting rights. Issuances of Preferred Stock, while providing the
Company with flexibility in connection with general corporate purposes, may,
among other things, have an adverse effect on the rights of holders of Common
Stock. The Company has no present plans to issue any Preferred Stock.
 
COVENANT RESTRICTIONS
 
     The Company's New Bank Credit Facility contains financial and operating
covenants, including restrictions on the ability of the Company to, among other
things, incur additional debt, make advances and investments, create, incur or
permit the existence of certain liens, make loans or guarantees and requires the
Company to achieve and maintain certain financial ratios, including minimum net
worth, maximum leverage ratio and minimum fixed charge coverage ratio.
 
     The terms of the indenture under which the Company will issue
$     ,000,000 of      % debentures which mature on           , 200 in
connection with the FELINE PRIDES Offering, prohibits the Company from declaring
or paying any dividends on or making any distributions with respect to its
Common Stock unless the Company has made at that time all quarterly payments of
interest on the debentures. See "Description of FELINE PRIDES Offering."
 
CERTAIN CHARTER AND BY-LAW PROVISIONS
 
     Certain provisions of the Restated Articles and Restated By-Laws could have
an anti-takeover effect. These provisions are intended to enhance the likelihood
of continuity and stability in the composition of the Company's Board of
Directors and in the policies formulated by the Board and to discourage an
unsolicited takeover of the Company if the Board determines that such takeover
is not in the best interests of the Company and its shareholders. However, these
provisions could have the effect of discouraging certain attempts to acquire the
Company or remove incumbent management even if some or a majority of
shareholders deemed such an attempt to be in their best interests.
 
     The provisions in the Restated Articles and Restated By-Laws include: (i)
the classification of the Board of Directors into three classes; (ii) a
procedure which requires shareholders to nominate directors in advance of a
 
                                      S-35
<PAGE>   237
 
meeting to elect such directors; and (iii) the authority to issue additional
shares of Common Stock or Preferred Stock without shareholder approval.
 
     The Restated Articles also include a provision requiring a 75 percent
shareholder vote for certain mergers or other business combinations or
transactions with five percent shareholders; a provision requiring a 75 percent
shareholder vote to remove the entire Board, a class of the Board, any
individual member of the Board without cause, or to increase the size of the
Board to more than twelve members or decrease the size of the Board to fewer
than eight members; a provision requiring disinterested shareholder approval of
stock repurchases at a premium over market by the Company from certain four
percent Shareholders (as defined in the Restated Articles); and a provision
requiring a majority of disinterested shareholders to approve certain business
combinations involving a stockholder who beneficially owns more than 10 percent
of the voting power of the Company, unless certain minimum price, form of
consideration and procedural requirements are satisfied or the transaction is
approved by a majority of disinterested directors.
 
     Pursuant to the Restated Articles, the Board of Directors is permitted to
consider the effects of a change in control on non-shareholder constituencies of
the Company, such as its employees, suppliers, creditors, customers and the
communities in which it operates. Pursuant to this provision, the Board may be
guided by factors in addition to price and other financial considerations.
 
     PBCL Anti-Takeover Provisions.  The Pennsylvania Business Corporation Law
(the "PBCL") contains a number of statutory "anti-takeover" provisions,
including Subchapters E, F, G and H of Chapter 25 and Section 2538 of the PBCL,
which apply automatically to a Pennsylvania registered corporation (usually a
public company) unless such corporation elects to opt-out as provided in such
provisions. The Company, as a Pennsylvania registered corporation, has elected
in its Restated By-Laws to opt-out of certain of the anti-takeover provisions
entirely, namely Subchapters G and the related H.
 
     The following descriptions are qualified in their entirety by reference to
such provisions of the PBCL:
 
          Subchapter E (relating to control transactions) generally provides
     that if any person or group acquires 20% or more of the voting power of a
     covered corporation, the remaining shareholders may demand from such person
     or group the fair value of their shares, including a proportionate amount
     of any control premium.
 
          Subchapter F (relating to business combinations) generally delays for
     five years and imposes conditions upon "business combinations" between an
     "interested shareholder" and the corporation. The term "business
     combination" is defined broadly to include various transactions between a
     corporation and an interested shareholder including mergers, sales or
     leases of specified amounts of assets, liquidations, reclassifications and
     issuances of specified amounts of additional shares of stock of the
     corporation. An "interested shareholder" is defined generally as the
     beneficial owner of at least 20% of a corporation's voting shares.
 
          Section 2538 of the PBCL generally establishes certain shareholder
     approval requirements with respect to specified transactions with
     "interested shareholders."
 
TRANSFER AGENT AND REGISTRAR
 
     ChaseMellon Shareholder Services, L.L.C. is the Transfer Agent and
Registrar for the Common Stock.
 
RIGHTS AGREEMENT
 
     The Company has adopted a rights plan pursuant to which the Board of
Directors authorized and the Company distributed one preferred stock purchase
right (each a "right") for each outstanding share of Common Stock of the
Company. The terms of the rights are governed by a Rights Agreement between the
Company and Mellon Bank, N.A., as Rights Agent, dated as of October 25, 1990
(the "Rights Agreement"). The rights, which currently are automatically
transferred with the related shares of Common Stock and are not separately
transferable, will entitle the holder thereof to purchase one-hundredth of a
share of a new series of preferred stock of the Company at a price of $105
(subject to certain adjustments).
 
     Subject to certain restrictions, the rights become exercisable only if a
person or group of persons acquires or intends to make a tender offer for 20
percent or more of the Company's Common Stock. If any person acquires
 
                                      S-36
<PAGE>   238
 
20 percent of the Common Stock, each right will entitle the shareholder to
receive upon exercise that number of shares of Common Stock having a market
value of two times the exercise price. If the Company is acquired in a merger or
certain other business combinations, each right then will entitle the
shareholder to purchase at the exercise price, that number of shares of the
acquiring company having a market value of two times the exercise price.
 
     The rights will expire on November 2, 2000, and are subject to redemption
in certain circumstances by the Company at a redemption price of $0.01 per
right.
 
     The foregoing summary description of the Rights Agreement does not purport
to be complete and is qualified in its entirety by reference to the Rights
Agreement, a copy of which has been filed with the Commission as an exhibit in
the Registration Statement of which this Prospectus forms a part. For a more
detailed description of the Rights Agreement, see the Company's Form 8-A filed
with the Commission with respect to the rights and incorporated by reference
into this Prospectus.

                     DESCRIPTION OF FELINE PRIDES OFFERING
 
     Concurrently with the Offerings, the Company and Kennametal Financing I are
offering        ,000,000 FELINE PRIDES. The gross proceeds from the FELINE
PRIDES Offering are expected to be approximately $     million ($     million if
the underwriters for the FELINE PRIDES Offering exercise their over-allotment
option in full). The consummation of the FELINE PRIDES Offering is not a
condition to the consummation of the Offerings.
 
     Each FELINE PRIDES offered hereby initially will consist of a unit
(referred to as an "Income PRIDES") with a Stated Amount of $50 (the "Stated
Amount") comprised of (a) a stock purchase contract (a "Purchase Contract")
under which (i) the holder will purchase from the Company on February 16, 2001
(the "Purchase Contract Settlement Date"), for an amount of cash equal to the
Stated Amount, a number of newly issued shares of the Common Stock of the
Company equal to the Settlement Rate described herein, and (ii) the Company will
pay the holder unsecured, subordinated contract adjustment payments ("Contract
Adjustment Payments") at the rate of        % of the Stated Amount per annum,
provided that if such rate is 0%, than the Company will not make any Contract
Adjustment Payments, and (b) either beneficial ownership of a        % Trust
Preferred Security(SM) (a "Trust Preferred Security"), having a stated
liquidation amount per Trust Preferred Security equal to the Stated Amount,
representing a preferred undivided beneficial interest in the assets of the
Trust or, upon the occurrence of a tax event redemption prior to the Purchase
Contract Settlement Date, the applicable ownership interest in the treasury
security portfolio.
 
     The number of new shares of Common Stock issuable upon settlement of each
Purchase Contract on the Purchase Contract Settlement Date (the "Settlement
Rate") will range from        to        shares and be calculated as follows
(subject to adjustment under certain circumstances): (a) if the Applicable
Market Value is equal to or greater than $          (the "Threshold Appreciation
Price"), the Settlement Rate will be           (b) if the Applicable Market
Value is less than the Threshold Appreciation Price but greater than
$          , the Settlement Rate will equal the Stated Amount divided by the
Applicable Market Value, and (c) if the Applicable Market Value is less than or
equal to $          , the Settlement Rate will be        . "Applicable Market
Value" means the average of the Closing Price (as defined) per share of Common
Stock on each of the thirty consecutive Trading Days (as defined) ending on the
third Trading Day immediately preceding the Purchase Contract Settlement Date.
 
     The Trust Preferred Securities have a stated liquidation amount per Trust
Preferred Security equal to the Stated Amount, and represent a preferred
undivided beneficial interest in the assets of Kennametal Financing I, a
Delaware business trust (the "Trust"). Kennametal owns all of the common equity
interests in the Trust. Holders of the Trust Preferred Securities are entitled
to receive cumulative cash distributions payable at the rate of     % of the
Stated Amount per annum. The sole asset of the Trust will consist of the
Company's      % Debentures, due February 3, 2003 (the "Debentures") and it will
make distributions only to the extent that the Company makes a corresponding
payment on the Debentures. The terms of the indenture pursuant to which the
Debentures will be issued permits the Company to defer quarterly payments of
interest on the Debentures by extending the payment dates for a period not to
exceed the maturity date of the Debentures. Any such deferred payments will
accrue interest at a compounded rate. During any such extension period, the
indenture provides that the Company may not declare or pay dividends on, make
distributions with respect to or repurchase (other than in certain limited
circumstances) its Common Stock. The Company has no present intention of
exercising its right to defer interest payments by extending the interest
payment period on the Debentures.
 
     The applicable distribution rate on the Trust Preferred Securities and the
interest rate on the related Debentures on and after the Purchase Contract
Settlement Date will be reset on the third Business Day (as defined) immediately
preceding the Purchase Contract Settlement Date to a rate per annum (the "Reset
Rate") to be determined by the Reset Agent (as defined herein) equal to the sum
of (x) a spread amount (the "Reset Spread") to be determined by the Reset Agent
on the tenth Business Day prior to the Purchase Contract Settlement Date and (y)
the rate of interest on the Two-Year Benchmark Treasury (as defined herein) in
effect on the third Business Day immediately preceding the Purchase Contract
Settlement Date, such sum being the distribution rate the Trust Preferred
Securities should bear in order for a Trust Preferred Security to have an
approximate market value of 100.5% of the Stated Amount on the third Business
Day immediately preceding the Purchase Contract Settlement Date, provided that
the Company may limit such Reset Spread to be no higher than 200 basis points
(2%). Such market value may be less than 100.5% if the Reset Spread is limited
to a maximum of 2%.

</TABLE>
 
     The Company has also entered into an international purchase agreement (the
"International Purchase Agreement") with certain underwriters outside the United
States and Canada (the "International Managers" and, together with the U.S.
Underwriters, the "Underwriters") for whom Merrill Lynch International, CIBC
Oppenheimer Corp., Goldman Sachs International and Lehman Brothers International
(Europe) are acting as lead managers (the "Lead Managers"). Subject to the terms
and conditions set forth in the International Purchase Agreement, and
concurrently with the sale of        shares of Common Stock to the U.S.
Underwriters pursuant to the U.S. Purchase Agreement, the Company has agreed to
sell to the International Managers, and the International Managers severally
have agreed to purchase from the Company, an aggregate of        shares of
Common Stock. The public offering price per share of Common Stock and the total
underwriting discount per share of Common Stock are identical under the U.S.
Purchase Agreement and the International Purchase Agreement.
 
     In the U.S. Purchase Agreement and the International Purchase Agreement,
the several U.S. Underwriters and the several International Managers,
respectively, have agreed, subject to the terms and conditions set forth
therein, to purchase all of the shares of Common Stock being sold pursuant to
each such agreement if any of the shares of Common Stock being sold pursuant to
such agreement are purchased. Under certain circumstances, under the U.S.
Purchase Agreement and the International Purchase Agreement, the commitments of
non-defaulting Underwriters may be increased. The closings with respect to the
sale of shares of Common Stock to be purchased by the U.S. Underwriters and the
International Managers are conditioned upon one another.
 
     The U.S. Representatives have advised the Company that the U.S.
Underwriters propose initially to offer the shares of Common Stock offered
hereby to the public at the public offering price set forth on the cover page of
this Prospectus Supplement, and to certain dealers at such price less a
concession not in excess of $       per share of Common Stock. The U.S.
Underwriters may allow, and such dealers may reallow, a discount not in excess
of $       per share of Common Stock on sales to certain other dealers. After
the public offering, the public offering price, concession and discount may be
changed.
 
     The Company has granted an option to the U.S. Underwriters, exercisable for
30 days after the date of this Prospectus Supplement, to purchase up to an
aggregate of        additional shares of Common Stock at the public offering
price set forth on the cover page of this Prospectus Supplement, less the
underwriting discount. The U.S. Underwriters may exercise this option only to
cover over-allotments, if any, made on the sale of the shares of Common Stock
offered hereby. To the extent that the U.S. Underwriters exercise this option,
each U.S. Underwriter will be obligated, subject to certain conditions, to
purchase a number of additional shares of Common Stock proportionate to such
U.S. Underwriter's initial amount reflected in the foregoing table. The Company
also has granted an option to the International Managers, exercisable for 30
days after the date of this
 
                                      S-39
<PAGE>   241
 
Prospectus Supplement, to purchase up to an aggregate of        additional
shares of Common Stock to cover over-allotments, if any, on terms similar to
those granted to the U.S. Underwriters.
 
     The Company has agreed not to (i) directly or indirectly, offer, pledge,
sell, contract to sell, sell any option or contract to purchase, purchase any
option or contract to sell, grant any option, right or warrant to purchase or
otherwise transfer or dispose of any shares of Common Stock or any securities
convertible into or exercisable or exchangeable for Common Stock or file any
registration statement under the Securities Act with respect to any of the
foregoing or (ii) enter into any swap or any other agreement or any transaction
that transfers, in whole or in part, directly or indirectly, the economic
consequence of ownership of the Common Stock or any securities convertible into
or exercisable or exchangeable for Common Stock whether any such swap or
transaction described in clause (i) or (ii) above is to be settled by delivery
of Common Stock or such other securities, in cash or otherwise, for a period of
90 days from the date of this Prospectus Supplement without the prior written
consent of Merrill Lynch, other than any shares of Common Stock: (i) to be sold
pursuant to the U.S. Purchase Agreement or the International Purchase Agreement;
(ii) issuable upon early settlement of the shares of FELINE PRIDES; (iii) issued
by the Company upon exercise of an option, warrant, or the conversion of a
security described herein (iv) issued, or options to purchase such shares
granted, pursuant to existing employee benefit plans described herein or (v)
issued pursuant to any non-employee director stock plan or dividend reinvestment
plan.
 
     The U.S. Underwriters and the International Managers have entered into an
intersyndicate agreement (the "Intersyndicate Agreement") that provides for the
coordination of their activities. Pursuant to the Intersyndicate Agreement, the
U.S. Underwriters and the International Managers are permitted to sell shares of
Common Stock to each other for purposes of resale at the public offering price,
less an amount not greater than the selling concession. Under the terms of the
Intersyndicate Agreement, the U.S. Underwriters and any dealer to whom they sell
shares of Common Stock will not offer to sell or sell shares of Common Stock to
persons who are non-U.S. or non-Canadian persons or to persons they believe
intend to resell to persons who are non-U.S. or non-Canadian persons, and the
International Managers and any dealer to whom they sell shares of Common Stock
will not offer to sell or sell shares of Common Stock to U.S. persons or to
Canadian persons or to persons they believe intend to resell to U.S. or Canadian
persons, except in the case of transactions pursuant to the Intersyndicate
Agreement.
 
     Each International Manager has agreed that: (i) it has not offered or sold
and, for a period of six months following consummation of the Offerings, will
not offer or sell any Common Stock to persons in the United Kingdom except to
persons whose ordinary activities involve them in acquiring, holding, managing
or disposing of investments (as principal or agent) for the purposes of their
businesses or otherwise in circumstances which do not constitute an offer to the
public in the United Kingdom within the meaning of the Public Offers of
Securities Regulations 1995; (ii) it has complied with and will comply with all
applicable provisions of the Public Offers of Securities Regulations 1995 and
the Financial Services Act 1986 with respect to anything done by it in relation
to the Common Stock in, from, or otherwise involving the United Kingdom; and
(iii) it has only issued or passed on and will only issue or pass on in the
United Kingdom any document received by it in connection with the issue or sale
of the Common Stock to a person who is of a kind described in Article 11(3) of
the Financial Services Act 1986 (Investment Advertisements) (Exemptions) Order
1996 or to a person to whom the document may otherwise lawfully be issued or
passed on.
 
     The Company has agreed to indemnify the U.S. Underwriters and the
International Managers against certain liabilities, including liabilities under
the Securities Act of 1933, as amended, or to contribute to payments the U.S.
Underwriters and the International Managers may be required to make in respect
hereof.
 
     Until the distribution of the shares of Common Stock is completed, rules of
the Securities and Exchange Commission may limit the ability of the Underwriters
and certain selling group members to bid for and purchase the Common Stock. As
an exception to these rules, the U.S. Representatives are permitted to engage in
certain transactions that stabilize the price of the shares of Common Stock.
Such transactions consist of bids or purchases for the purpose of pegging,
fixing or maintaining the price of shares of Common Stock.
 
     If the Underwriters create a short position in the Common Stock in
connection with the Offerings, i.e., if they sell more shares of Common Stock
than are set forth on the cover page of the Prospectus Supplement, the U.S.
Representatives may reduce that short position by purchasing shares of Common
Stock in the open market.
 
                                      S-40
<PAGE>   242
 
The U.S. Representatives may also elect to reduce any short position by
exercising all or part of the over-allotment option described above.
 
     The U.S. Representatives may also impose a penalty bid on certain
Underwriters and selling group members. This means that if the U.S.
Representatives purchase shares of Common Stock in the open market to reduce the
Underwriters' short position or to stabilize the price of the shares of Common
Stock, they may reclaim the amount of the selling concession from the
Underwriters and selling group members who sold those shares as part of the
Offerings.
 
     In general, purchases of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher than
it might be in the absence of such purchases. The imposition of a penalty bid
might also have an effect on the price of the Common Stock to the extent that it
discourages resales of the shares of Common Stock.
 
     Neither the Company nor any of the Underwriters makes any representation or
prediction as to the direction or magnitude of any effect that the transactions
described above may have on the price of the Common Stock. In addition, neither
the Company nor any of the Underwriters makes any representation that the U.S.
Representatives will engage in such transactions or that such transactions, once
commenced, will not be discontinued without notice.
 
     Merrill Lynch has from time to time provided investment banking advisory
services to the Company, for which it has received customary compensation, and
may continue to do so in the future. Merrill Lynch has acted as financial
advisor to the Company in connection with the Merger, including serving as
dealer manager with respect to the Tender Offer. In this regard, the Company has
agreed to indemnify Merrill Lynch against certain liabilities. CIBC Oppenheimer
Corp., Goldman, Sachs & Co. and Lehman Brothers Inc. have from time to time
provided investment banking or financial advisory services to the Company, and
may continue to do so in the future.
 
                                 LEGAL MATTERS
 
     The validity of the shares of Common Stock being offered hereby will be

                                    EXPERTS
 
     The consolidated financial statements of the Company as of June 30, 1996
and June 30, 1997 and for each of the three years in the period ended June 30,
1997, included in this Prospectus and elsewhere in the Registration Statement,

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Shareholders of Kennametal Inc.
 
We have audited the accompanying consolidated balance sheets of Kennametal Inc.
and subsidiaries as of June 30, 1996 and 1997, and the related consolidated
statements of income, shareholders' equity and cash flows for each of the three
years in the period ended June 30, 1997. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Kennametal Inc. and
subsidiaries as of June 30, 1996 and 1997, and the results of their operations
and their cash flows for each of the three years in the period ended June 30,
1997, in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1. NATURE OF OPERATIONS
 
     The Company is a global enterprise engaged in the manufacture, purchase and
distribution of a broad range of tools, tooling systems, supplies and services
for the metalworking, mining and highway construction industries.
 
NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     The summary of significant accounting policies is presented below to assist
in evaluating the Company's consolidated financial statements.
 
     PRINCIPLES OF CONSOLIDATION. The consolidated financial statements include
the accounts of the Company and its majority-owned subsidiaries. All significant
intercompany balances and transactions have been eliminated.
 
     USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS. The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
     CASH EQUIVALENTS. Temporary cash investments having original maturities of
three months or less are considered cash equivalents. Cash equivalents consist
principally of investments in money market funds and certificates of deposit.
 
     ACCOUNTS RECEIVABLE included $16.6 million and $12.8 million of receivables
from affiliates at June 30, 1996 and 1997, respectively.
 
     INVENTORIES are carried at the lower of cost or market. The Company uses
the last-in, first-out (LIFO) method for determining the cost of a significant
portion of its U.S. inventories. The remainder of inventories is determined
under the first-in, first-out (FIFO) or average cost methods.
 
     PROPERTY, PLANT AND EQUIPMENT are carried at cost. Major improvements are
capitalized, while maintenance and repairs are generally expensed as incurred.
Retirements and disposals are removed from cost and accumulated depreciation
accounts, with the gain or loss reflected in income. Interest is capitalized
during the construction of major facilities. Capitalized interest is included in
the cost of the constructed asset and is amortized over its estimated useful
life.
 
     Depreciation for financial reporting purposes is computed using the
straight-line method over the estimated useful lives of the assets ranging from
3 to 40 years. Leased property and equipment under capital leases are amortized
using the straight-line method over the terms of the related leases.
 
     INTANGIBLE ASSETS, which include the excess of cost over net assets of
acquired companies, are amortized using the straight-line method over periods
ranging from 3 to 40 years. The Company assesses the recoverability of goodwill
by determining whether the amortization of the goodwill balance over its
remaining life can be recovered through undiscounted future operating cash flows
of the acquired entities.
 
     RESEARCH AND DEVELOPMENT COSTS are expensed as incurred.
 
     INCOME TAXES. Deferred income taxes are recognized based on the future
income tax effects (using enacted tax laws and rates) of differences in the
carrying amounts of assets and liabilities for financial reporting and tax
purposes. A valuation allowance is recognized if it is "more likely than not"
that some or all of a deferred tax asset will not be realized.
 
     FOREIGN CURRENCY TRANSLATION. For the most part, assets and liabilities of
international operations are translated into U.S. dollars using year-end
exchange rates, while revenues and expenses are translated at average

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
 
exchange rates throughout the year. The resulting net translation adjustments
are recorded as a separate component of shareholders' equity.
 
     PENSION PLANS cover substantially all employees. Pension benefits are based
on years of service and, for certain plans, on average compensation immediately
preceding retirement. Pension costs are determined in accordance with Statement
of Financial Accounting Standards (SFAS) No. 87, "Employers' Accounting for
Pensions." The Company funds pension costs in accordance with the funding
requirements of the Employee Retirement Income Security Act of 1974 (ERISA) for
U.S. plans and in accordance with local regulations or customs for non-U.S.
plans.
 
     EARNINGS PER SHARE is computed using the weighted average number of shares
outstanding during the year.
 
     REVENUE RECOGNITION. The Company recognizes revenue from product sales upon
transfer of title to the customer.
 
     NEW ACCOUNTING STANDARDS. Effective July 1, 1996, the Company adopted SFAS
No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed of." The adoption of SFAS No. 121 did not have an impact
on the consolidated financial statements, as the statement is consistent with
existing Company policy.
 
     Additionally on July 1, 1996, the Company adopted SFAS No. 123, "Accounting
for Stock-Based Compensation." Under the provisions of SFAS No. 123, companies
may elect to account for stock-based compensation plans using a fair-value-based
method or may continue measuring compensation expense for those plans using the
intrinsic-value-based method. The Company will continue to use the
intrinsic-value-based method, which does not result in compensation cost. The
Company's stock compensation plans are discussed in Note 13.
 
     The Financial Accounting Standards Board recently issued SFAS No. 128,
"Earnings Per Share" and SFAS No. 129, "Disclosure of Information about Capital
Structures." SFAS No. 128 was issued in February 1997 and is effective for
periods ending after December 15, 1997. This statement, upon adoption, will
require all prior period earnings per share (EPS) data to be restated to conform
to the provisions of the statement. This statement's objective is to simplify
the computations of EPS and to make the U.S. standard for EPS computations more
compatible with that of the International Accounting Standards Committee. The
Company will adopt SFAS No. 128 in fiscal 1998 and does not anticipate that the
statement will have a significant impact on its reported EPS.
 
     SFAS No. 129 was issued in February 1997 and is effective for periods
ending after December 15, 1997. This statement, upon adoption, will require all
companies to provide specific disclosure regarding their capital structure. SFAS
No. 129 will specify the disclosure for all companies, including descriptions of
their capital structure and the contractual rights of the holders of such
securities. The Company will adopt SFAS No. 129 in fiscal 1998 and does not
anticipate that the statement will have a significant impact on its disclosures.
 
     Additionally, in June 1997, the FASB issued SFAS No. 130, "Reporting
Comprehensive Income" (SFAS No. 130) and SFAS No. 131, "Disclosures About
Segments of an Enterprise and Related Information" (SFAS No. 131). SFAS No. 130
is effective for years ending after December 15, 1997. SFAS No. 130 establishes
standards for reporting and display of comprehensive income and its components
in a full set of general-purpose financial statements. The Company will adopt
SFAS No. 130 in fiscal 1998 and does not anticipate that the statement will have
a significant impact on its disclosures.
 
     SFAS No. 131 introduces a new model for segment reporting called the
"management approach." The management approach is based on the way the chief
operating decision-maker organizes segments within a company for making

     INTERIM UNAUDITED FINANCIAL INFORMATION. The consolidated financial
statements as of, and for the three months ended September 30, 1996 and 1997 are
unaudited; however, in the opinion of management all adjustments (consisting
solely of normal recurring adjustments) necessary for a fair presentation have
been made. The results of interim periods are not necessarily indicative of the
results to be expected for the full fiscal year.
 
NOTE 3. ISSUANCE OF SUBSIDIARY STOCK
 
     On July 2, 1997, an initial public offering (IPO) of approximately 4.9
million shares of common stock at a price of $20 per share of JLK Direct
Distribution Inc. (JLK), a newly formed subsidiary of the Company, was
consummated. JLK operates the industrial supply operations consisting of the
Company's wholly owned J&L Industrial Supply (J&L) subsidiary and its Full
Service Supply programs. The net proceeds from the offering were approximately
$90 million and represented approximately 20 percent of JLK's common stock. The
transaction was accounted for as an equity transaction in the consolidated
financial statements. The net proceeds were used by JLK to repay $20 million of
indebtedness related to a dividend to the Company and $20 million related to
intercompany obligations to the Company. The Company used these proceeds to
repay short-term debt. In connection with the IPO, the remaining net proceeds
were loaned to the Company, under an intercompany debt/investment and cash
management agreement at a fluctuating rate of interest equal to the Company's
short-term borrowing costs. The Company will maintain unused lines of credit to
enable it to repay any portion of the borrowed funds as the amounts are due on
demand by JLK.
 
     The Company owns approximately 80 percent of the outstanding common stock
of JLK and intends to retain a majority of both the economic and voting
interests of JLK.

     Inventories are stated at the lower of cost or market. Cost is determined
using the last-in, first-out (LIFO) method for a significant portion of U.S.
inventories and the first-in, first-out (FIFO) method or average cost for other
inventories. The Company used the LIFO method of valuing its inventories for
approximately 55 and 56 percent of total inventories at June 30, 1996 and 1997,
respectively, and for approximately 45 percent of total inventories at September
30, 1997. The Company uses the LIFO method for valuing the majority of its
inventories in order to more closely match current costs with current revenues,
thereby reducing the effects of inflation on earnings.

NOTE 7. NOTES PAYABLE AND LINES OF CREDIT
 
     Notes payable to banks of $57.5 million and $120.2 million at June 30, 1996
and 1997, respectively, represent short-term borrowings under U.S. and
international credit lines with commercial banks. These credit lines totaled
approximately $280 million at June 30, 1997, of which $160 million was unused.
The weighted average interest rate for short-term borrowings was 5.6 percent and
6.3 percent at June 30, 1996 and 1997, respectively.
 
     The Company has available U.S. credit lines totaling $175 million that are
covered by a revolving credit agreement that amounts to $150 million and another
agreement totaling $25 million. The revolving credit agreement allows the
Company to borrow up to $150 million at fixed or variable interest rates. This
credit line expires during fiscal 2001 and requires the Company to pay a
facility fee on the total line. The Company has the option to terminate this
agreement in whole or in part at any time.
 
     During 1997, the Company's J&L subsidiary obtained a $25 million line of
credit with a bank and borrowed $20 million under the line of credit to fund a
dividend to the Company. Interest payable under the line of credit was based on
LIBOR plus 25 basis points. The Company guaranteed repayment of the line of
credit in the event of default by J&L. The line of credit was repaid and
canceled in full during July 1997.

     Deferred income taxes have not been provided on cumulative undistributed
earnings of international subsidiaries and affiliates. Any U.S. income taxes on
such earnings, if distributed, would generally be offset by available foreign
tax credits. In addition, there were no significant undistributed earnings of
unconsolidated affiliates at June 30, 1997.

     Included in deferred tax assets at June 30, 1997, are unrealized tax
benefits totaling $27.2 million related to net operating loss carryforwards. The
realization of these tax benefits is contingent on future taxable income in
certain international operations. Of this amount, approximately $23.6 million
relates to net operating loss carryforwards in Germany, which can be carried
forward indefinitely. The Company's operations in Germany are profitable.
 
     The remaining unrealized tax benefits relate to net operating loss
carryforwards in certain other international operations, which expire at various
dates through 2002. The Company established a valuation allowance of $3.6
million to offset the deferred tax benefits that may not be realized before the
expiration of the carryforward periods.

NOTE 10. OTHER POSTRETIREMENT AND POSTEMPLOYMENT BENEFITS
 
     The Company presently provides varying levels of postretirement health care
and life insurance benefits to most U.S. employees. Postretirement health care
benefits are available to employees and their spouses retiring at or after age
65 with five or more years of service after age 40. Employees (and their
spouses) retiring under age 65 before January 1, 1998, with 20 or more years of
service after age 40 also are eligible to receive postretirement health care
benefits. Beginning with retirements on or after January 1, 1998, Kennametal's
portion of the costs of postretirement health care benefits will be capped at
1996 levels.

       Ultimate rate in 2003 and after..................................  5.00%      5.00%
</TABLE>
 
     A 1 percent increase in the health care cost trend rate would have
increased other postretirement benefit costs by $0.1 million in 1997 and the
accumulated benefit obligation by $1.0 million at June 30, 1997.
 
     The Company provides for postemployment benefits pursuant to SFAS No. 112,
"Employers' Accounting for Postemployment Benefits." The Company accrues the
cost of separation and other benefits provided to former or inactive employees
after employment but before retirement. Postemployment benefit costs were not
significant in 1995, 1996 and 1997, respectively.
 
NOTE 11. RESTRUCTURING CHARGE
 
     On April 29, 1996, the Board of Directors approved the Company's plan (the
Plan) to relocate its North America Metalworking Headquarters from Raleigh,
North Carolina, to Latrobe, Pennsylvania. In connection with the Plan, the
Company is constructing a new world headquarters at an estimated cost of $20
million. The relocation was made to globalize key functions and to provide a
more efficient corporate structure. The action affected approximately 300
employees in Raleigh, North Carolina, all of whom were offered the opportunity
to move to Latrobe, Pennsylvania. As a result, a pretax charge of $2.0 million
was recorded in the fourth quarter of fiscal 1996. The charge was taken to cover
the one-time costs of employee separation arrangements and early retirement
costs.
 
     The costs resulting from the relocation of employees, hiring and training
new employees, and other costs resulting from the temporary duplication of
certain operations were not included in the one-time charge and will be included
in operating expenses as incurred. The costs related to these items were
estimated to be approximately $9.0 million pretax, $4.7 million that was
recorded in fiscal 1997 and the remainder that will be incurred in fiscal 1998.
 
     During the fourth quarter of fiscal 1996, the Company also recorded a
one-time pretax charge of $0.7 million related to the closure of a manufacturing
facility in Canada. The supply of products produced at this location will be
continued from other Company locations. The restructuring was substantially
complete in 1997.
 
NOTE 12. FINANCIAL INSTRUMENTS
 
     FAIR VALUE.  The Company had $21.9 million in cash and equivalents at June
30, 1997, which approximates fair value because of the short maturity of these
investments.
 
     The estimated fair value of term debt was $44.9 million at June 30, 1997.
Fair value was determined using discounted cash flow analysis and the Company's
incremental borrowing rates for similar types of arrangements.
 
     OFF-BALANCE-SHEET RISK.  The Company uses forward foreign exchange
contracts in the normal course of business to hedge foreign currency exposures
of underlying receivables and payables. These financial instruments involve
credit risk in excess of the amount recognized in the financial statements. The
Company controls credit risk through credit evaluations, limits and monitoring
procedures. There were no financial instruments with significant
off-balance-sheet risk at June 30, 1997.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
 
     CONCENTRATIONS OF CREDIT RISK.  Financial instruments that potentially
subject the Company to concentrations of credit risk consist primarily of
temporary cash investments and trade receivables. By policy, the Company makes
temporary cash investments with high credit quality financial institutions. With
respect to trade receivables, concentrations of credit risk are significantly
reduced because the Company serves numerous customers in many industries and
geographic areas. As of June 30, 1997, the Company had no significant
concentrations of credit risk.
 
NOTE 13. STOCK OPTIONS
 
     Under stock option plans approved by shareholders in 1996, 1992 and 1988,
stock options generally are granted to eligible employees at fair market value
at the date of grant. Options are exercisable under specified conditions for up
to 10 years from the date of grant. No options may be granted under the 1988
plan after October 1998, no options may be granted under the 1992 plan after
October 2002, and no options may be granted under the 1996 plan after October
2006. No charges to income have resulted from the operation of the plans.
 
     Under provisions of the plans, participants may deliver Kennametal stock in
payment of the option price and receive credit for the fair market value of the
shares on the date of delivery. Shares valued at $0.4 million (13,728 shares),
$0.9 million (22,740 shares) and $0.5 million (11,684 shares) were delivered in
1995, 1996 and 1997, respectively.
 
     Under the 1996, 1992 and 1988 plans, shares may be awarded to eligible
employees without payment. The respective plans specify such shares are awarded
in the name of the employee, who has all the rights of a shareholder, subject to
certain restrictions or forfeitures. Such awards were not significant in 1995,
1996 and 1997.
 
     The Company adopted the disclosure requirements of SFAS No. 123 effective
with the 1997 consolidated financial statements, but elected to continue to
measure compensation expense in accordance with Accounting Principles Board
Opinion No. 25, "Accounting for Stock Issued to Employees." Accordingly, no
compensation expense for stock options has been recognized in the accompanying
consolidated financial statements. If compensation expense had been determined
based on the estimated fair value of options granted in 1996 and 1997,
consistent with the methodology in SFAS No. 123, the effect on the Company's
1996 and 1997 net income and earnings per share would have been reduced to the
pro forma amounts indicated below:

NOTE 14. ENVIRONMENTAL MATTERS
 
     The Company has been involved in various environmental cleanup and
remediation activities at several of its manufacturing facilities. In addition,
the Company has been named as a potentially responsible party at several
Superfund sites in the United States. However, it is management's opinion, based
on its evaluations and discussions with outside counsel and independent
consultants, that the ultimate resolution of these environmental matters will
not have a material adverse effect on the results of operations, financial
position or cash flows of the Company.
 
     The Company maintains a Corporate Environmental, Health and Safety (EH&S)
Department as well as an EH&S Policy Committee to ensure compliance with
environmental regulations and to monitor and oversee remediation activities. In
addition, the Company has established an EH&S administrator at each of its
domestic manufacturing facilities. The Company's financial management team
periodically meets with members of the Corporate EH&S Department and the
Corporate Legal Department to review and evaluate the status of environmental
projects and contingencies. On a quarterly and annual basis, management
establishes or adjusts financial provisions and reserves for environmental
contingencies in accordance with SFAS No. 5, "Accounting for Contingencies."

NOTE 15. SHAREHOLDER RIGHTS PLAN
 
     Pursuant to the Company's Shareholder Rights Plan, one-half of a right is
associated with each share of capital stock. Each right entitles a shareholder
to buy 1/100th of a share of a new series of preferred stock at a price of $105
(subject to adjustment).
 
     The rights will be exercisable only if a person or group of persons
acquires or intends to make a tender offer for 20 percent or more of the
Company's capital stock. If any person acquires 20 percent of the capital stock,
each right will entitle the shareholder to receive that number of shares of
capital stock having a market value of two times the exercise price. If the
Company is acquired in a merger or other business combination, each right will
entitle the shareholder to purchase at the exercise price that number of shares
of the acquiring Company having a market value of two times the exercise price.
The rights will expire on November 2, 2000, and are subject to redemption by the
Company at $0.01 per right.
 
NOTE 16. ACQUISITIONS
 
     Fiscal 1997 results included sales of approximately $16 million from five
companies acquired during the year for a total consideration of approximately
$19 million. The acquisitions were accounted for using the purchase method of
accounting. The consolidated financial statements include the operating results
of each business from the date of acquisition. Pro forma results of operations
have not been presented because the effects of these acquisitions were not
significant.

     Intersegment transfers are accounted for at arm's-length prices, reflecting
prevailing market conditions within the various geographic areas. Such sales and
associated costs are eliminated in the consolidated financial statements.
 
     Identifiable assets are those assets that are identified with the
operations in each geographic area. Corporate assets consist mainly of cash and
cash equivalents, investments in affiliated companies and other assets.
 
     Sales to a single customer did not aggregate 10 percent or more of total
sales. Export sales from U.S. operations to unaffiliated customers were $27.4
million, $21.4 million and $15.1 million in 1995, 1996 and 1997, respectively.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
 
NOTE 18. SUBSEQUENT EVENTS
 
     The Company recently acquired Rubig G.m.b.H. of Munich, Germany, Presto
Engineers Cutting Tools Limited of Sheffield, United Kingdom, and Car-Max Tool &
Cutter Sales, Inc. The companies had aggregate annual sales of approximately $46
million in 1996. The acquisitions were accounted for using the purchase method
of accounting. The consolidated financial statements include the operating
results of each business from the date of acquisition. The Company has recently
entered into an agreement to acquire GRS Industrial Supply Company with annual
sales of approximately $20 million in 1996.
 
     On October 10, 1997, Kennametal and Kennametal Acquisition Corp.
(Acquisition Corp.) entered into the Merger Agreement with Greenfield pursuant
to which Acquisition Corp. purchased at $38 per share on November 17, 1997,
approximately 16,179,976 shares (98% of the outstanding) of Greenfield's common
stock. The Merger occurred on November 18, 1997, and Greenfield became a
wholly-owned subsidiary of Kennametal on that date. The total purchase price for
the acquisition of Greenfield (including estimated transaction costs and assumed
Greenfield debt and convertible redeemable preferred securities of approximately
$320 million) is estimated to be $1.0 billion.
 
     In connection with the acquisition of Greenfield, the Company, on November
17, 1997, entered into the New Bank Credit Facility. As of November 18, 1997,
the Company had borrowed $500 million in term loans and approximately $300
million in revolving credit loans under the New Bank Credit Facility. The
proceeds from these loans were principally used to pay for the shares of common
stock of Greenfield purchased in the Tender Offer and the Merger, to pay
transaction costs, to refinance certain indebtedness of Greenfield and to
refinance certain indebtedness of the Company. Subject to certain conditions,
the New Bank Credit Facility permits revolving credit loans of up to $900
million for working capital requirements, capital expenditures, and general
corporate purposes. The New Bank Credit Facility initially will be secured by
all of the stock of certain of Kennametal's significant domestic subsidiaries,
by guarantees of certain of such subsidiaries and by 65% of the stock of
Kennametal's significant foreign subsidiaries. The New Bank Credit Facility
contains various restrictive covenants and affirmative covenants requiring the
maintenance of certain financial ratios. The term loans under the New Bank
Credit Facility are subject to mandatory prepayments commencing on November 30,
1998, and all loans mature on August 31, 2002. Proceeds from the Common Stock
Offerings and the Feline PRIDES Offering will be used to prepay term loans under
the New Bank Credit Facility.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders
of Greenfield Industries, Inc.
 
     In our opinion, the accompanying consolidated balance sheets and the
related consolidated statements of operations, of changes in stockholders'
equity and of cash flows present fairly, in all material respects, the financial
position of Greenfield Industries, Inc. and its subsidiaries at December 31,
1995 and 1996, and the results of their operations and their cash flows for each
of the three years in the period ended December 31, 1996, in conformity with
generally accepted accounting principles. These financial statements are the
responsibility of the Company's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with generally accepted auditing
standards which require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

                 (DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)
 
1. BUSINESS
 
     Greenfield Industries, Inc. (Greenfield or the Company) is a global
manufacturer of expendable products for material cutting, material removal and
wear applications used in various industries. The Company also manufactures a
limited number of products (primarily bilge pumps) for the marine industry. The
Company markets its products through six product groups which are as follows:
(1) industrial products, (2) engineered products, (3) energy and construction
products, (4) electronics products, (5) consumer products, and (6) marine
products. The majority of the Company's products are made from either high-speed
steel or tungsten carbide. The Company's largest concentration of business is in
North America but it sells its products throughout the world.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     The policies utilized by the Company in the preparation of the consolidated
financial statements conform to generally accepted accounting principles, and
require management to make estimates and assumptions that affect the reported
amounts of assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual amounts could differ from these estimates.
 
     The significant accounting policies followed by the Company are described
below.
 
REVENUE RECOGNITION
 
     Revenue from the sale of the Company's products is recognized upon shipment
to the customer.
 
PRINCIPLES OF CONSOLIDATION
 
     The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries. All significant intercompany transactions and
balances are eliminated in consolidation.
 
INTERIM UNAUDITED FINANCIAL INFORMATION
 
     The interim consolidated financial information at September 30, 1997 and
for the nine months ended September 30, 1996 and 1997 and related disclosures in
the notes herein (including Note 18) is unaudited. However, in the opinion of
management, such information has been prepared on the same basis as the audited
consolidated financial statements and includes all adjustments, consisting only
of normal recurring adjustments, necessary for a fair presentation of the
results of operations for the periods presented. The interim results, however,
are not necessarily indicative of the results for any future period.
 
FOREIGN CURRENCY TRANSLATION
 
     The accounts of the Company's foreign subsidiaries are maintained in their
respective local currencies. The accompanying consolidated financial statements
have been translated and adjusted to reflect U.S. dollars on the bases presented
below.
 
     Assets and liabilities are translated into U.S. dollars at year-end
exchange rates. Income and expense items are translated at average rates of
exchange prevailing during the year. Adjustments resulting from the process of
translating the consolidated amounts into U.S. dollars are accumulated in a
separate translation adjustment account included in stockholders' equity. Common
stock and additional paid-in capital are translated at historical U.S. dollar
equivalents in effect at the date of acquisition. Foreign currency transaction
gains and losses are included in earnings currently. The Company recognized net
foreign currency transaction gains of $227, $540 and $599 for the years ended
December 31, 1994, 1995 and 1996, respectively.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
 
CASH
 
     For purposes of the consolidated statements of cash flows, the Company
considers all highly liquid investments with an original maturity of three
months or less to be cash. Cash overdrafts, if any, on the Company's
disbursement accounts are included in the balances outstanding under the
Company's revolving credit facilities.
 
CONCENTRATION OF CREDIT RISK
 
     The Company sells its products to distributors and end-users in the
industrial, energy and construction, electronics, engineered products, consumer
and marine markets. While most of the Company's business activity is with
customers located within North America, the Company also serves customers in
Europe and the Far East. The Company performs ongoing credit evaluations of its
customers and generally does not require collateral. The Company maintains
reserves for potential credit losses and historically such losses have been
within management's expectations. At December 31, 1996, the Company had no
significant concentrations of credit risk.
 
RELATIONSHIPS WITH SUPPLIERS
 
     The Company purchases tungsten carbide materials from multiple suppliers,
for which alternative suppliers also exist and are adequate. Although the
Company purchases the majority of its domestic high-speed steel requirements
from a single supplier, the Company believes that the supply of steel and the
number of alternative suppliers are adequate. The Company considers its
relationships with its primary suppliers to be strong.
 
INVENTORIES
 
     Inventories are stated at the lower of cost or market. Cost is determined
using the last-in, first-out (LIFO) method, for substantially all domestic
inventories. For various tax and statutory reasons, inventories of the Company's
foreign subsidiaries are stated at first-in, first-out (FIFO) cost. The effects
on the consolidated financial position and results of operations from applying
the FIFO method (versus the LIFO method) to certain inventories are immaterial.
If the FIFO method (which approximates replacement cost) had been used in
determining cost for all inventories, inventories would have been approximately
$5,181 and $5,675 higher at December 31, 1995 and 1996, respectively.
Inventories include the cost of materials, direct labor and manufacturing
overhead. Obsolete or unsaleable inventories are reflected at their estimated
net realizable values.
 
PROPERTY, PLANT AND EQUIPMENT
 
     Property, plant and equipment is carried at cost and is depreciated using
the straight-line method over the estimated useful lives of the assets which
range from 3 to 40 years. Properties held under capital leases are recorded at
the present value of the noncancelable lease payments over the term of the lease
and are amortized over the shorter of the lease term or the estimated useful
lives of the assets. Expenditures for repairs, maintenance and renewals are
charged to income as incurred. Expenditures which improve an asset or extend its
estimated useful life are capitalized. When properties are retired or otherwise
disposed of, the related cost and accumulated depreciation are removed from the
accounts and any gain or loss is included in income.
 
GOODWILL
 
     The excess of the purchase price over the fair value of net assets acquired
in business combinations is capitalized and amortized on a straight-line basis
over the estimated period benefited. The amortization period for all
acquisitions to date is 40 years. Amortization expense for the years ended
December 31, 1994, 1995 and 1996 was approximately $1,221, $2,636 and $4,279,
respectively. Accumulated amortization at December 31, 1995 and 1996 was
approximately $7,592 and $11,849, respectively. The carrying value of goodwill
is assessed for recoverability by management based on current and anticipated
conditions, including expected cash flows and

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
 
operating results generated by the underlying tangible assets. Management
believes that there has been no impairment at December 31, 1996.
 
OTHER ASSETS
 
     Other assets are primarily comprised of debt issuance and trademark costs.
At December 31, 1995, other assets also included an investment in Rule
Industries, Inc. stock as further described in Note 3. Debt issuance costs are
being amortized on a straight-line basis over the life of the related obligation
and trademarks are being amortized on a straight-line basis over 40 years.
Amortization expense for the years ended December 31, 1994, 1995 and 1996 was
approximately $270, $272 and $341, respectively. Accumulated amortization at
December 31, 1995 and 1996 was $3,471 and $3,568, respectively.
 
INCOME TAXES
 
     The Company accounts for income taxes under Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes" (FAS 109). Under FAS
109, the deferred tax provision is determined using the liability method,
whereby deferred tax assets and liabilities are recognized based upon temporary
differences between the financial statement and income tax bases of assets and
liabilities using presently enacted tax rates.
 
EARNINGS PER SHARE
 
     Fully diluted earnings per share primarily reflect the effects of
conversion of the Company's mandatorily redeemable convertible preferred
securities and elimination of the related dividends, net of applicable income
taxes (see Note 5). Primary earnings per share is computed by dividing net
income available to common stockholders by the weighted average number of common
and common equivalent shares outstanding during the period. Options under the
Company's employee and directors stock option plans are not included as common
stock equivalents for earnings per share purposes since they did not have a
material dilutive effect.
 
ENVIRONMENTAL LIABILITIES
 
     Environmental expenditures that relate to current operations are expensed
or capitalized as appropriate. Expenditures that relate to an existing condition
caused by past operations, and that do not contribute to current or future
revenue generation, are expensed. Liabilities are recorded when environmental
assessments and/or remedial efforts are probable, and the costs can be
reasonably estimated.
 
EMPLOYEE STOCK-BASED COMPENSATION
 
     The Company accounts for employee stock options and variable stock awards
in accordance with Accounting Principles Board No. 25, "Accounting for Stock
Issued to Employees" (APB 25). Under APB 25, the Company applies the intrinsic
value method of accounting. For employee stock options accounted for using the
intrinsic value method, no compensation expense is recognized because the
options are granted with an exercise price equal to the market value of the
stock on the date of grant. For variable stock awards accounted for using the
intrinsic value method, compensation cost is estimated and recorded each period
from the date of grant to the measurement date based on the market value of the
stock at the end of each period.
 
     During 1996, Statement of Financial Accounting Standards No. 123,
"Accounting for Stock-Based Compensation" (FAS 123), became effective for the
Company. FAS 123 prescribes the recognition of compensation expense based on the
fair value of options or stock awards determined on the date of grant. However,
FAS 123 allows companies to continue to apply the valuation methods set forth in
APB 25. For companies that continue to apply the valuation methods set forth in
APB 25, FAS 123 mandates certain pro forma disclosures as if the fair value
method had been utilized. See Note 12 for additional discussion.

</TABLE>
 
     During the past three years, the Company has made several acquisitions
which have significantly expanded its product lines. These acquisitions were
each accounted for using the purchase method of accounting and financed
primarily through bank borrowings, resulting in an increase in the Company's
outstanding debt. Results of operations of each acquired company have been
included in the Company's consolidated financial statements from the date of
acquisition. The purchase price of each acquisition was allocated to the assets
acquired and liabilities assumed based on their estimated fair value at the date
of acquisition. The excess of purchase price over the estimated fair value of
net assets acquired was, in each instance, recorded as goodwill. Except for
Rule, CTD and Carbidie, the pro forma effects, individually and collectively, of
the acquisitions on the Company's consolidated results of operations and
financial position are not material.
 
     The following table sets forth pro forma information for the Company as if
the acquisitions of Rule, CTD and Carbidie had taken place on January 1, 1994
and the acquisition of Rule had taken place on January 1, 1995, respectively.
This information is unaudited and does not purport to represent actual revenue,
net income and earnings per share had the acquisitions actually occurred on
January 1, 1994 and 1995, respectively. The pro forma effects of Rule, had the
acquisition taken place on January 1, 1996, are not material.

     In connection with a definitive merger agreement between Rule and the
Company, on September 11, 1995 Greenfield exercised its option to acquire
630,000 shares of Rule common stock for approximately $5,611, including
acquisition costs. The cost of the Rule common stock is reflected as other
assets on the December 31, 1995 consolidated balance sheet. On January 12, 1996,
Greenfield acquired the remaining outstanding shares of Rule common stock as
discussed further below.

     In connection with the Company's acquisition of Rule in January 1996, the
Company recorded a restructuring reserve of $2,600 in purchase accounting
primarily related to the closing of two Rule facilities (including the corporate
office) and the involuntary termination of a substantial number of Rule
employees. Of the $2,600 reserve, $1,240 related to employee severance costs,
$346 related to the closure of the two facilities, and $1,014 related to other
nonrecurring costs associated with terminating certain Rule operations. This
restructuring has resulted in a reduction in personnel and the elimination of
certain duplicate functions. The employee severance costs related to the
reduction of approximately 62 employees from the acquisition date. Of the total
$2,600 reserve, substantially all of the costs had been paid as of December 31,
1996.
 
     The Company, as part of the acquisition of CTD, recorded a restructuring
and plant consolidation liability of $10,480 in purchase accounting relating to
the consolidation of certain facilities of CTD into existing facilities of the
Company. The $10,480 liability included $8,430 in costs associated with plant
closures, $2,000 in severance pay and $50 in other costs. Substantially all of
these costs had been paid as of December 31, 1996.
 
     On March 27, 1997, the Company acquired the outstanding shares of Hanita
Metal Works, Ltd., an Israeli-based company, and its U.S. subsidiary Hanita
Cutting Tools, Inc. (collectively, Hanita) for approximately $20,800 (including
cash acquired) and assumed indebtedness of approximately $14,600. Hanita, with
its primary manufacturing, sales and distribution operations in Israel, is a
leading manufacturer of high-quality, high performance end mills and other
cutting tools for the metalworking industry. Hanita also sells and distributes
products around the world, including the United States. The acquisition was
accounted for using the purchase method of accounting and was financed through
the Company's existing unsecured credit facility. For the year ended December
31, 1996, Hanita had net sales of approximately $27,000. The pro forma effects
of the acquisition on the Company's results of operations are not material. The
results of operations of Hanita are included in the Company's consolidated
financial statements from the date of acquisition.

domestic unsecured revolving credit facilities. The new agreement provides for a
$130,000 multi-currency unsecured revolving facility and a $50,000 U.S. dollar
acquisition facility. The multi-currency revolving facility provides for loans
of up to DM 30,000 and Sterling 15,000. The facility requires commitment fees of
0.20% or 0.25% per annum (as determined by the Company's ratio of total
indebtedness to cash flow) payable quarterly on any unused portion of the multi-
currency facility. As of December 31, 1996 and September 30, 1997, interest on
borrowings under the multi-currency facility ranged from 6.3% to 8.3% per annum
and from 4.0% to 8.2% per annum, respectively. At December 31, 1996 and

existing indebtedness and for general corporate purposes.
 
     On August 16, 1995, the Company, through CTD, issued $7,200 in City of
Solon, Ohio Industrial Development Revenue Bonds (The Cleveland Twist Drill
Company Project) Series 1995 (Ohio Bonds) to pay for the construction of a new

     On March 31, 1995, the Company, in conjunction with the South Carolina
Jobs-Economic Development Authority, issued $7,200 in Tax-Exempt Adjustable Mode

expansion of its facility in Clemson, South Carolina. The South Carolina Bonds
mature on March 1, 2015 and bear interest at 4.3% at December 31, 1996. The
proceeds from the South Carolina Bonds are held in trust until needed for the
expansion. Approximately $5,602 has been received from the South Carolina Bonds

foreign credit facility. The amended agreement provided for a DM 21 million
unsecured credit facility and a Sterling 4.5 million unsecured credit facility.
In connection with the acquisition of Cleveland Europe Limited, during December

Sterling Facility to Sterling 9.5 million. As discussed above, this foreign
revolving credit facility was replaced in December 1996.
 
     During November 1994, the Company amended its existing unsecured credit
facility. The amended agreement provided for a $110,000 domestic revolving
facility and a $20,000 acquisition facility. The facility required commitment
fees of 0.25% or 0.375% per annum (as determined by the Company's ratio of total
indebtedness to cash flow) payable quarterly on any unused portion of the
domestic and foreign revolving credit facilities. As discussed above, the
domestic revolving facility and the acquisition facility were replaced in
December 1996.
 
     The financing agreements contain provisions which limit additional
borrowings and capital expenditures, require maintenance of certain debt to
capital and debt to cash flow ratios and net worth levels. At December 31, 1995
and 1996, and at September 30, 1997, the Company was in compliance with such
provisions.

5. MANDATORILY REDEEMABLE CONVERTIBLE PREFERRED SECURITIES
 
     On April 24, 1996, the Company completed a private placement to
institutional investors of $115,000 of 6% Convertible Preferred Securities
(liquidation preference of $50 per Convertible Preferred Security). The
placement was made through the Company's wholly-owned subsidiary, Greenfield
Capital Trust (Trust), a newly-formed Delaware business trust. The securities
represent undivided beneficial ownership interests in the Trust. The sole asset
of the Trust is the $118,557 aggregate principal amount of the 6% Convertible
Junior Subordinated Deferrable Interest Debentures Due 2016 which were acquired
with the proceeds from the private placement of the Convertible Preferred
Securities and the offering and sale of Common Securities to the Company. The
Company's obligations under the Convertible Junior Subordinated Debentures, the
Indenture pursuant to which they were issued, the Amended and Restated
Declaration of Trust of the Trust and the Guarantee of Greenfield, taken
together, constitute a full and unconditional guarantee by Greenfield of amounts
due on the Convertible Preferred Securities. The Convertible Preferred
Securities are convertible at the option of the holders at any time into the
common stock of Greenfield at an effective conversion price of $41.25 per share
and are redeemable at Greenfield's option after April 15, 1999. The net proceeds
of the offering of approximately $110,746 were used by Greenfield to retire
indebtedness. A registration statement relating to resales of such Convertible
Preferred Securities was declared effective by the Securities and Exchange
Commission on September 26, 1996.
 
     Upon consummation of the merger described in Note 18, the effective
conversion price of the Convertible Preferred Securities was adjusted to
approximately $36.05.
 
6. LEASE COMMITMENTS
 
     The Company leases certain of its equipment under noncancelable lease
agreements. These agreements extend for a period of up to 42 months and contain
purchase or renewal options on a month-to-month basis. The leases are reflected
in the consolidated financial statements as capitalized leases in accordance
with the requirements of Statement of Financial Accounting Standards No. 13,
"Accounting for Leases."

     The deferred tax asset valuation allowance at December 31, 1996 primarily
represents excess deductible temporary differences over taxable temporary
differences for foreign operations and potential nonrealization of certain other
deferred tax assets. The tax benefits, if any, from the future recognition of
certain deductible temporary differences present at the date of the acquisition
of CTD and Rule, but not recognized at that time, will be applied to reduce
goodwill.
 
     The provision for income taxes differs from the amount of income tax
determined by applying the applicable U.S. statutory federal income tax rate to
pretax income as a result of the following differences:

8. RESTRUCTURING COSTS
 
     The results of operations for the year ended December 31, 1996 included
restructuring costs of $4,000 (approximately $2,400 net of related tax benefits,
or $0.15 per common share), on a primary basis. These costs were primarily
related to employee severance and certain other nonrecurring charges resulting
from the effects of the reorganization of the Company's business groups. The
restructuring costs included the costs associated with the combination or
elimination of certain functions or operations which were identified as
redundant. The $4,000 restructuring charge recorded in the third quarter
included $2,727 for employee-related costs consisting primarily

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
 
of severance costs, $585 for the noncash write-down of plant assets where
operations have been or will be terminated, and $688 for other nonrecurring
severance costs for personnel that have been terminated or will be terminated in
future periods. The employee severance costs relate to the reduction of
approximately 42 employees as of December 31, 1996 and future reductions of
approximately 28 employees. Of the total $4,000 charge, approximately $777 had
been incurred through December 31, 1996. The remaining accrual primarily relates
to employee severance costs and costs associated with the closure of two
facilities.
 
     During 1994, the Company recorded restructuring costs of $1,300 relating to
the consolidation of the plant in Switzerland into a plant in Germany. The
$1,300 charge is comprised of $700 in costs associated with plant closures and
relocation of machinery and equipment, $500 in severance costs related to
approximately 35 administrative staff and plant personnel at the closed Swiss
facility and $100 in other costs. The Company substantially completed the
restructuring by the end of 1994.
 
     The Company continues to evaluate its operations with an intent to
streamline operations, improve productivity and reduce costs and may implement
additional rationalization programs in the future.
 
9. RETIREMENT PLANS
 
     The Company offers substantially all of its domestic employees a retirement
savings plan under Section 401(k) of the Internal Revenue Code. Employees may
elect to enter a written salary deferral agreement under which a maximum of 15%
of their salaries may be contributed to the plan, subject to aggregate limits
required under the Internal Revenue Code. The Company is required to make a
mandatory contribution of 2% of qualified employee earnings. In addition, the
Company will match a percentage of the employees' contribution up to a specified
maximum percentage of their salaries and may make a discretionary contribution
from profits upon resolution of its Board of Directors. For the years ended
December 31, 1994, 1995 and 1996, the Company made contributions to the defined
contribution plans of approximately $2,448, $3,406 and $3,923, respectively.
 
     CTD, Carbidie and AMT had defined benefit pension plans covering
substantially all domestic employees with the exception of AMT non-union
employees when they were acquired by the Company. All of these plans were frozen
in 1995, and benefits were frozen at 1995 levels. In addition, Rule had a
defined benefit pension plan for certain employees for which the benefits had
been frozen prior to the Company's acquisition of Rule in January 1996. The
Company's funding policy with respect to such plans is to contribute annually
the minimum amount required under ERISA. Plan assets include marketable equity
securities, U.S. government securities, federal agency obligations, corporate
debt instruments, money market funds and other fixed income securities.
 
     In connection with the CTD and Carbidie acquisitions in 1994, the Company
recorded an aggregate net liability of $6,051 in purchase accounting
representing the excess of the estimated projected benefit obligation (PBO) over
the fair value of plan assets. During 1996, the Company recorded a net liability
of $700 in purchase accounting for the excess of the PBO over the fair value of
the plan assets in connection with the Rule acquisition.
 
     The following tables set forth the defined benefit pension plans' net
periodic pension costs for the years ended December 31, 1995 and 1996 and the
plans' net funded status, amounts recorded in the consolidated balance sheet,
and other summary information at December 31, 1995 and 1996:

10. POSTRETIREMENT BENEFITS
 
     Under Statement of Financial Accounting Standards No. 106, "Employers'
Accounting for Postretirement Benefits Other Than Pensions," the Company is
required to recognize the cost of providing health care and other benefits to
retirees over the term of the employees' service. Prior to the acquisitions of
CTD and Carbidie, the Company provided no postretirement benefits other than
those related to the 401(k) plans described in Note 9. CTD and a certain other
subsidiary provides health care insurance benefits to certain of its retired
employees. All of these plans were frozen in 1995, and benefits were frozen at
1995 levels. In connection with the CTD acquisition in 1994, the Company
recorded a liability of $11,939 in purchase accounting representing the
estimated discounted present value of the expected future retiree benefits
attributed to employees' service rendered in periods prior to Greenfield's
acquisition.
 
     The following tables set forth the plans' net periodic postretirement
benefit cost for the years ended December 31, 1995 and 1996, the accumulated
postretirement benefit obligation (APBO) at December 31, 1995 and 1996 and other
summary information:

and 1996 decreased gradually to 6% (until 2002 and thereafter). If the assumed
health care cost trend rates were increased by 1%, the APBO for 1995 and 1996
would have increased approximately $558 and $434, respectively.

     There are no plan assets and the Company expects to continue to fund these
benefit costs on a pay-as-you-go basis. During 1995 and 1996, the Company made
payments of approximately $1,018 and $1,400, respectively, related to these
benefits.
 
11. 1993 EXECUTIVE STOCK OPTIONS
 
     In 1993, the Company established the 1993-1 Executive Stock Option Plan
(1993-1 Plan) and granted to certain officers of Rogers Tool Works, Inc., a
wholly-owned subsidiary of the Company (RTW), non-qualified stock options to
purchase an aggregate of 438,258 shares of common stock at a price of $0.51 per
share, subject to adjustment, in exchange for the cancellation of RTW shares
held by these officers. In addition, the Company cancelled the promissory notes
of each of these officers issued to finance the purchase of their RTW shares.
The exercise price with respect to the options granted was determined to
preserve the original purchase price per share of the RTW shares cancelled. The
options became exercisable as to 25% of the shares issuable thereunder on
January 26, 1994, and as to a cumulative 35%, 50% and 100% of the shares
issuable thereunder on each succeeding six-month anniversary thereof. As of
December 31, 1995 all of the options had been exercised. During the years ended
December 31, 1994 and 1995, 153,367 and 284,891 shares, respectively, were
issued in connection with the 1993-1 Plan.
 
     In 1993, the Company also adopted the 1993-2 Executive Stock Option Plan
(1993-2 Plan) pursuant to which nonqualified stock options were granted to
certain existing shareholders prior to the initial public offering to acquire an
aggregate 453,350 shares of the Company's common stock, subject to adjustment,
by tendering existing common stock in payment thereof. The exercise price of all
options was the current market price on the date of exercise and all options
were exercised only by exchanging shares of previously owned common stock. The
grant and exercise of options under the 1993-2 Plan did not result in any
increase in the beneficial ownership of common stock by the plan participants
from the number of shares owned immediately after the initial public offering.
Under the terms of the 1993-2 Plan, the options were exercised immediately after
the initial public offering and the shares of common stock issued thereunder
became freely transferable by each participant as to 25% of the shares issuable
to such participants on January 31, 1994 and as to a cumulative 35%, 50% and
100% of the shares issuable to such participant on each succeeding six-month
anniversary thereof. The shares tendered in exercise of options granted under
the 1993-2 Plan were issued under promissory notes due in 1998 through 2002. The
notes are reflected in stock subscriptions receivable, included in additional
paid-in capital and other, in the accompanying consolidated financial
statements.
 
12. STOCK OPTION AND STOCK INCENTIVE PLANS
 
STOCK OPTION PLANS
 
     The Company has three stock options plans: the Employee Stock Option Plan
(Employee Plan), the 1995 Directors Non-Qualified Stock Option Plan (Directors
Plan) and the 1993 Directors Non-Qualified Stock Option Plan (1993 Directors
Plan).
 
     The Employee Plan provides for the granting of options to purchase up to
1,000,000 shares of common stock to the Company's executive officers and key
employees at prices equal to the fair market value of the stock on the date of
grant. The Employee Plan was amended effective May 6, 1997, to, among other
things, increase the number of options to purchase shares of common stock from
1,000,000 to 2,000,000. Options outstanding at December 31, 1996 entitle the
holders to purchase common stock at prices ranging between $16.00 and $37.00 per
share, subject to adjustment. Options shall become exercisable with respect to
one-fourth of the shares covered thereby on each anniversary of the date of
grant, commencing on the second anniversary of such date. The right to exercise
the options expires ten years from the date of grant, or earlier if an option
holder ceases to be employed by the Company.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
 
     The Directors Plan provides for the granting of options to purchase up to
125,000 shares of common stock to the Company's Directors who are not employees
of the Company at prices equal to the fair market value of the stock on the date
of grant. Options are granted to each eligible Director on the date such person
is first elected to the board of directors of the Company and on each subsequent
re-election date. The Directors Plan was approved in May 1996 by the
stockholders. Options outstanding at December 31, 1996 entitle the holders to
purchase common stock at a price of $37.00 per share, subject to adjustment.
Options granted upon re-election shall become exercisable in full on the first
anniversary of such date. All other options shall become exercisable with
respect to one-fourth of the shares covered thereby on each anniversary date of
the date of grant, commencing on the second anniversary of such date. The right
to exercise the options expires ten years from the date of grant, or earlier, if
an option holder ceases to be a Director of the Company.
 
     The 1993 Directors Plan provides for the granting of options to purchase up
to 100,000 shares of common stock to the Company's Directors who are not
employees of the Company at prices equal to the fair market value of the stock
on the date of grant. Options are granted to each eligible Director on the date
such person is first elected to the board of directors of the Company. Options
outstanding at December 31, 1996 entitle the holders to purchase common stock at
prices ranging between $15.50 and $25.75 per share, subject to adjustment.
Options shall become exercisable with respect to one-fourth of the shares
covered thereby on each anniversary of the date of grant, commencing on the
second anniversary of such date. The right to exercise the options expires ten
years from the date of grant, or earlier if an option holder ceases to be a
Director of the Company. Subsequent to the May 1996 approval of the Directors
Plan, no further grants will be issued under the 1993 Directors Plan.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
 
     In connection with the resignation of a member of the Company's Board of
Directors, in 1994 the Company exchanged options for 10,000 shares of common
stock previously granted to the Director with a warrant to purchase 10,000
shares of common stock at an exercise price equal to the exercise price of the
options.
 
STOCK INCENTIVE PLANS
 
     The Company has two stock incentive plans: the 1995 Equity Incentive Plan
(Incentive Plan) and the 1995 Restricted Stock Bonus Plan (Ownership Plan). Both
plans were approved in May 1996 by the stockholders of the Company.
 
     The Incentive Plan provides for the granting of up to 273,000 shares of
common stock to certain senior executives of the Company in time-lapse
restricted stock, performance contingent restricted stock and performance
shares. Time-lapse restricted stock vests in one-third increments over a
three-year period commencing four years after the date of the award. Performance
contingent restricted stock is earned when the price for the Company's stock
reaches certain predetermined levels, and then vests over a three- or five-year
period. Performance shares are earned based on attainment of a predetermined
four-year cumulative earnings per share level. Attainment of between 50% and
200% of the predetermined objective will entitle the participants to receive
restricted performance shares of between 50% and 200% of the target award, which
then vest over a three-year period. No performance shares are earned if less
than 50% of the performance objective is obtained.
 
     The Ownership Plan provides for the issuance of up to 250,000 shares of
common stock to certain employees, by allowing such employees to elect to defer
up to 50% of their annual cash bonus and receive, in lieu thereof, shares of the
Company's common stock. The Company will increase the employees' deferred bonus
by either 20% or 35% (depending on the employees' selection of 3 or 5 years,
respectively, for the restriction period).
 
     Shares issued under these plans are restricted and are subject to
forfeiture upon termination of employment. During the period that the shares are
restricted, award holders have the right to vote and to receive dividends on
such shares.
 
     A summary of stock earned and issued pursuant to the Incentive Plan and
Ownership Plan for the year ended December 31, 1996 follows:

</TABLE>
 
     The Company awarded up to 273,000 shares of restricted stock to certain
senior executives under the Incentive Plan, subject to the attainment of certain
performance levels, as discussed above. The weighted average fair value of the
shares on the grant date was $30.73. The Company applies APB 25 and related
interpretations in accounting for stock awards under the Incentive and Ownership
Plans. Under APB 25, the Company recorded $1,500 of compensation expense during
1996 attributable to these awards, which is included in selling, general and
administrative expenses in the 1996 consolidated statement of operations.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
 
     Shares which have been issued but which remain restricted are recorded as
deferred compensation, a reduction to additional paid-in capital. The increase
in additional paid-in capital of $761 during 1996 represents the issuance of
executive stock awards and is net of this deferred compensation. As the shares
vest and become unrestricted, the deferred compensation will be recorded as
compensation expense and additional paid-in capital will increase.
 
PRO FORMA DISCLOSURES
 
     The Company applies APB 25 and related interpretations in accounting for
its stock option plans. Accordingly, except for the Incentive and Ownership
Plans as described above, no compensation cost has been recognized for the stock
options because the options were granted with an exercise price equal to the
stock price on the date of grant. Had compensation costs for the Company's stock
option plans been determined based on the fair value of the options on the grant
dates consistent with the methodology prescribed by FAS 123, the Company's net
income and earnings per share would have been reduced to the pro forma amounts
indicated below. Due to the adoption of the methodology prescribed by FAS 123,
the pro forma results shown below only reflect the impact of options and stock
awards granted in 1995 and 1996. Because future options and stock awards may be
granted, the pro forma impact for 1995 and 1996 is not necessarily indicative of
the impact in future years.

13. RELATED PARTIES
 
     Harbour Group Investments, L.P. (HGI, L.P.) was the Company's principal
stockholder prior to HGI, L.P.'s sale of substantially all of its shares in a
secondary stock offering in March 1994. Under terms of a corporate development
consulting and advisory services agreement, the Company incurred fees totaling
$1,109, $445 and $580 in 1994, 1995 and 1996, respectively, payable to an
affiliate of HGI, L.P. related to corporate development services provided in
identifying, negotiating and consummating certain acquisitions.
 
     Under terms of a management consulting and advisory services agreement,
Harbour Group, Ltd. (HGL), an affiliate of HGI, L.P., charges the Company for
direct management and administrative services provided to the Company based on
HGL's approximate costs for such services. These charges totaled approximately
$250, $182 and $53 for the years ended December 31, 1994, 1995 and 1996,
respectively, and are reflected in selling, general and administrative expenses
in the accompanying consolidated financial statements.

                          GREENFIELD INDUSTRIES, INC.
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
 
     At December 31, 1995 and 1996, a member of HGL management owned 80,000
shares of the Company's common stock partially financed with promissory notes
totaling $101 due in 1998 through 2003. The notes are reflected in stock
subscriptions receivable, included in additional paid-in capital and other, in
the accompanying consolidated financial statements.
 
14. COMMITMENTS AND CONTINGENCIES
 
     The Company is involved in certain claims and legal proceedings in which
monetary damages are sought. The Company is vigorously contesting these claims.
However, resolution of these claims is not expected to occur quickly and their
ultimate outcome presently cannot be predicted. It is the opinion of management
that any liability of the Company for claims or proceedings will not materially
affect its financial position.
 
     In connection with the acquisition of CTD, the Company recorded a liability
of $2,600 in purchase accounting for certain estimated environmental clean-up
costs to be incurred relative to acquired CTD facilities. This estimated
potential liability, which is included in other accrued liabilities, has not
been reduced for any expected proceeds from other potentially responsible third
parties. At December 31, 1996, the liability balance was approximately $2,200.
 
15. SEGMENT INFORMATION
 
     Worldwide operations data, as required by Statement of Financial Accounting
Standards No. 14, "Financial Reporting for Segments of a Business Enterprise,"
are listed below. Profitability of the Company's foreign operations by
geographic area was determined based on ultimate sales to unaffiliated
customers. Income from operations was included in the geographic area of the
entity transacting the final sale. Intercompany sales have been eliminated in
consolidation.

18. SUBSEQUENT EVENTS (UNAUDITED)
 
     On October 10, 1997, the Company entered into a definitive merger agreement
with Kennametal Inc. (Kennametal), whereby Kennametal Acquisition Corp. (a
wholly-owned subsidiary of Kennametal) commenced a tender offer on October 17,
1997 for all of the outstanding shares of the Company for $38 per share. The
tender offer expired on November 14, 1997 and approximately 98% of the Company's
shares were tendered. The merger was completed on November 18, 1997. Under the
terms of the merger agreement, all outstanding options to acquire shares of the
Company were cancelled in exchange for a payment equal to the difference between
$38 per share and the strike price.
 
     In the fourth quarter of 1997, pursuant to a plan approved by the Company's
board of directors, the Company recorded a $11.5 million charge for nonrecurring
expenses primarily related to the restructuring of the Company's South
Deerfield, Massachusetts operations. These costs primarily included write-downs
of inventory

and machinery and equipment to estimated net realizable values, severance costs
and other miscellaneous expenses relative to the Company's decision to
discontinue the manufacture and sale of certain low margin product lines. The
restructuring will result in a reduction in personnel, thereby eliminating
excessive costs and redundancies in future periods. The Company expects to
record additional nonrecurring expenses of approximately $2.0 million in 1998
related to the rearrangement of the remaining operations at its South Deerfield,
Massachusetts facility.

               CERTAIN U.S. TAX CONSEQUENCES TO NON-U.S. HOLDERS
 
     The following is a general discussion of certain United States federal
income and estate tax consequences of the ownership and disposition of Common
Stock by a Non-U.S. Holder. For this purpose, a "Non-U.S. Holder" is any person
who is, for United States federal income tax purposes, a foreign corporation, a
non-resident alien individual, a foreign partnership or a foreign estate or
trust. This discussion does not address all aspects of United States federal
income and estate taxes and does not deal with foreign, state and local
consequences that may be relevant to such Non-U.S. Holders in light of their
personal circumstances. Furthermore, this discussion is based on provisions of
the Internal Revenue Code of 1986, as amended (the "Code"), existing and
proposed regulations promulgated thereunder and administrative and judicial
interpretations thereof, as of the date hereof, all of which are subject to
change. EACH PROSPECTIVE PURCHASER OF COMMON STOCK IS ADVISED TO CONSULT A TAX
ADVISOR WITH RESPECT TO CURRENT AND POSSIBLE FUTURE TAX CONSEQUENCES OF
ACQUIRING, HOLDING AND DISPOSING OF COMMON STOCK AS WELL AS ANY TAX CONSEQUENCES
THAT MAY ARISE UNDER THE LAWS OF ANY U.S. STATE, MUNICIPALITY OR OTHER TAXING
JURISDICTION.
 
DIVIDENDS
 
     Dividends paid to a Non-U.S. Holder of Common Stock generally will be
subject to withholding of United States federal income tax at a 30% rate or such
lower rate as may be specified by an applicable income tax treaty. However,
dividends that are effectively connected with the conduct of a trade or business
by the Non-U.S. Holder within the United States or, where certain tax treaties
apply, are attributable to a United States permanent establishment of the
Non-U.S. Holder, are not subject to the withholding tax, but instead are subject
to United States federal income tax on a net income basis at applicable
graduated individual or corporate rates. Certain certification and disclosure
requirements must be complied with in order to be exempt from withholding under
such effectively connected income exemption. Any such effectively connected
dividends received by a foreign corporation may, under certain circumstances, be
subject to an additional "branch profits tax" at a 30% rate or such lower rate
as may be specified by an applicable income tax treaty.
 
     Under current law, dividends paid to an address outside the United States
are presumed to be paid to a resident of such country (unless the payer has
knowledge to the contrary) for purposes of the withholding tax discussed above
and, under the current interpretation of United States Treasury regulations, for
purposes of determining the applicability of a tax treaty rate. Under recently
finalized United States Treasury regulations (the "Final Regulations"), a
Non-U.S. Holder of Common Stock who wishes to claim the benefit of an applicable
treaty rate (and avoid back-up withholding as discussed below) for dividends
paid after December 31, 1998, will be required to satisfy applicable
certification and other requirements.
 
     A Non-U.S. Holder of Common Stock eligible for a reduced rate of United
States withholding tax pursuant to an income tax treaty may obtain a refund of
any excess amounts withheld by filing an appropriate claim for refund with the
Internal Revenue Service (the "IRS").
 
GAIN ON DISPOSITION OF COMMON STOCK
 
     A Non-U.S. Holder generally will not be subject to United States federal
income tax with respect to gain recognized on a sale or other disposition of
Common Stock unless (i) the gain is effectively connected with a trade or
business of the Non-U.S. Holder in the United States, or, where certain tax
treaties apply, is attributable to a United States permanent establishment of
the Non-U.S. Holder, (ii) in the case of a Non-U.S. Holder who is an individual
and holds the Common Stock as a capital asset, such holder is present in the
United States for 183 or more days in the taxable year of the sale or other
disposition and certain other conditions are met, or (iii) the Company is or has
been a "U.S. real property holding corporation" for United States federal income
tax purposes. The Company does not believe that it is or will become a U.S. real
property holding corporation.
 
     An individual Non-U.S. Holder described in clause (i) above will be subject
to tax on the net gain derived from the sale under regular graduated United
States federal income tax rates. An individual Non-U.S. Holder described in
clause (ii) above will be subject to a flat 30% tax on the gain derived from the
sale, which may be
<PAGE>   292
 
                                                                [ALTERNATE PAGE]
 
offset by United States source capital losses (even though the individual is not
considered a resident of the United States). If a Non-U.S. Holder that is a
foreign corporation falls under clause (i) above, it will be subject to tax on
its gain under regular graduated United States federal income tax rates and, in
addition, may be subject to the branch and profits within the meaning of the
Code for the taxable year, as adjusted for certain items, unless it qualifies
for a lower rate under an applicable income tax treaty.
 
FEDERAL ESTATE TAX
 
     Common Stock held by an individual Non-U.S. Holder at the time of death
will be included in such holder's gross estate for United States federal estate
tax purposes, unless an applicable estate tax treaty provides otherwise.
 
INFORMATION REPORTING AND BACK-UP WITHHOLDING
 
     The Company must report annually to the IRS and to each Non-U.S. Holder the
amount of dividends paid to such holder and the tax withheld with respect to
such dividends, regardless of whether withholding was required. Copies of the
information returns reporting such dividends and withholding may also be made
available to the tax authorities in the country in which the Non-U.S. Holder
resides under the provisions of an applicable income tax treaty.
 
     Under current law, back-up withholding at the rate of 31% generally will
not apply to dividends paid to a Non-U.S. Holder at an address outside the
United States (unless the payer has knowledge that the payee is a U.S. person).
Under the Final Regulations, however, a Non-U.S. Holder will be subject to
back-up withholding unless applicable certification requirements are met.
 
     Payment of the proceeds of a sale of Common Stock by or through a United
States office of a broker is subject to both back-up withholding and information
reporting unless the beneficial owner certifies under penalties of perjury that
it is a Non-U.S. Holder or otherwise establishes an exemption. In general,
back-up withholding and information reporting will not apply to a payment of the
proceeds of a sale of Common Stock by or through a foreign office of a broker.
If, however, such person, a controlled foreign corporation, or a foreign person
that derives 50% or more of its gross income for a certain period from the
conduct of a trade or business in the United States, such payments will be
subject to information reporting, but not back-up withholding, unless (1) such
broker has documentary evidence in its records that the beneficial owner is a
Non-U.S. Holder and certain other conditions are met, or (2) the beneficial
owner otherwise establishes an exemption.
 
     Any amounts withheld under the back-up withholding rules may be allowed as
a refund or a credit against such holder's U.S. federal income tax liability
provided the required information is furnished to the IRS.

                                  UNDERWRITING
 
     Merrill Lynch International, CIBC Oppenheimer Corp., Goldman Sachs
International and Lehman Brothers International (Europe) are acting as lead
managers (the "Lead Managers") for certain underwriters outside the United
States and Canada (the "International Managers"). Subject to the terms and
conditions set forth in an international purchase agreement (the "International
Purchase Agreement") among the Company and the International Managers, and
concurrently with the sale of        shares of Common Stock to the U.S.
Underwriters (as defined below), the Company has agreed to sell to the
International Managers, and each of the International Managers severally and not
jointly has agreed to purchase from the Company, the number of shares of Common
Stock set forth opposite its name below.

</TABLE>
 
     The Company has also entered into a U.S. purchase agreement (the "U.S.
Purchase Agreement") with certain underwriters in the United States and Canada
(the "U.S. Underwriters" and, together with the International Managers, the
"Underwriters") for whom Merrill Lynch, Pierce, Fenner & Smith Incorporated
("Merrill Lynch"), CIBC Oppenheimer Corp., Goldman, Sachs & Co. and Lehman
Brothers Inc. are acting as representatives (the "U.S. Representatives") of each
of the U.S. Underwriters. Subject to the terms and conditions set forth in the
U.S. Purchase Agreement, and concurrently with the sale of        shares of
Common Stock to the International Managers, the Company has agreed to sell to
the U.S. Underwriters, and each of the U.S. Underwriters severally and not
jointly has agreed to purchase from the Company, an aggregate of        shares
of Common Stock. The public offering price per share of Common Stock and the
total underwriting discount per share of Common Stock are identical under the
International Purchase Agreement and the U.S. Purchase Agreement.
 
     In the International Purchase Agreement and the U.S. Purchase Agreement,
the several International Managers and the several U.S. Underwriters,
respectively, have agreed, subject to the terms and conditions set forth
therein, to purchase all of the shares of Common Stock being sold pursuant to
each such agreement if any of the shares of Common Stock being sold pursuant to
such agreement are purchased. Under certain circumstances, under the
International Purchase Agreement and the U.S. Purchase Agreement, the
commitments of non-defaulting Underwriters may be increased. The closings with
respect to the sale of shares of Common Stock to be purchased by the
International Managers and the U.S. Underwriters are conditioned upon one
another.
 
     The Lead Managers have advised the Company that the International Managers
propose initially to offer the shares of Common Stock offered hereby to the
public at the public offering price set forth on the cover page of this
Prospectus Supplement, and to certain dealers at such price less a concession
not in excess of $       per share of Common Stock. The International Managers
may allow, and such dealers may reallow, a discount not in excess of $       per
share of Common Stock on sales to certain other dealers. After the public
offering, the public offering price, concession and discount may be changed.
 
     The Company has granted an option to the International Managers,
exercisable for 30 days after the date of this Prospectus Supplement, to
purchase up to an aggregate of        additional shares of Common Stock at the
public offering price set forth on the cover page of this Prospectus Supplement,
less the underwriting discount. The International Managers may exercise this
option only to cover over-allotments, if any, made on the sale of the shares of
Common Stock offered hereby. To the extent that the International Managers
exercise this option, each International Manager will be obligated, subject to
certain conditions, to purchase a number of additional shares of Common Stock
proportionate to such International Manager's initial amount reflected in the
foregoing table. The Company also has granted an option to the U.S.
Underwriters, exercisable for 30 days after the date of this

Prospectus Supplement, to purchase up to an aggregate of        additional
shares of Common Stock to cover over-allotments, if any, on terms similar to
those granted to the International Managers.
 
     The Company has agreed not to (i) directly or indirectly, offer, pledge,
sell, contract to sell, sell any option or contract to purchase, purchase any
option or contract to sell, grant any option, right or warrant to purchase or
otherwise transfer or dispose of any shares of Common Stock or any securities
convertible into or exercisable or exchangeable for Common Stock or file any
registration statement under the Securities Act with respect to any of the
foregoing or (ii) enter into any swap or any other agreement or any transaction
that transfers, in whole or in part, directly or indirectly, the economic
consequence of ownership of the Common Stock or any securities convertible into
or exercisable or exchangeable for Common Stock whether any such swap or
transaction described in clause (i) or (ii) above is to be settled by delivery
of Common Stock or such other securities, in cash or otherwise, for a period of
90 days from the date of this Prospectus Supplement without the prior written
consent of Merrill Lynch, other than any shares of Common Stock: (i) to be sold
pursuant to the International Purchase Agreement or the U.S. Purchase Agreement;
(ii) issuable upon early settlement of the shares of FELINE PRIDES; (iii) issued
by the Company upon exercise of an option, warrant, or the conversion of a
security described herein (iv) issued, or options to purchase such shares
granted, pursuant to existing employee benefit plans described herein or (v)
issued pursuant to any non-employee director stock plan or dividend reinvestment
plan.
 
     The International Managers and the U.S. Underwriters have entered into an
intersyndicate agreement (the "Intersyndicate Agreement") that provides for the
coordination of their activities. Pursuant to the Intersyndicate Agreement, the
International Managers and the U.S. Underwriters are permitted to sell shares of
Common Stock to each other for purposes of resale at the public offering price,
less an amount not greater than the selling concession. Under the terms of the
Intersyndicate Agreement, the International Managers and any dealer to whom they
sell shares of Common Stock will not offer to sell or sell shares of Common
Stock to U.S. persons or to Canadian persons or to persons they believe intend
to resell to U.S. or Canadian persons, and the U.S. Underwriters and any dealer
to whom they sell shares of Common Stock will not offer to sell or sell shares
of Common Stock to persons who are non-U.S. or non-Canadian persons or to
persons they believe intend to resell to persons who are non-U.S. or
non-Canadian persons, except in the case of transactions pursuant to the
Intersyndicate Agreement.
 
     Each International Manager has agreed that: (i) it has not offered or sold
and, for a period of six months following consummation of the Offerings, will
not offer or sell any Common Stock to persons in the United Kingdom except to
persons whose ordinary activities involve them in acquiring, holding, managing
or disposing of investments (as principal or agent) for the purposes of their
businesses or otherwise in circumstances which do not constitute an offer to the
public in the United Kingdom within the meaning of the Public Offers of
Securities Regulations 1995; (ii) it has complied with and will comply with all
applicable provisions of the Public Offers of Securities Regulations 1995 and
the Financial Services Act 1986 with respect to anything done by it in relation
to the Common Stock in, from, or otherwise involving the United Kingdom; and
(iii) it has only issued or passed on and will only issue or pass on in the
United Kingdom any document received by it in connection with the issue or sale
of the Common Stock to a person who is of a kind described in Article 11(3) of
the Financial Services Act 1986 (Investment Advertisements) (Exemptions) Order
1996 or to a person to whom the document may otherwise lawfully be issued or
passed on.
 
     The Company has agreed to indemnify the International Managers and the U.S.
Underwriters against certain liabilities, including liabilities under the
Securities Act of 1933, as amended, or to contribute to payments the
International Managers and the U.S. Underwriters may be required to make in
respect hereof.
 
     Until the distribution of the shares of Common Stock is completed, rules of
the Securities and Exchange Commission may limit the ability of the Underwriters
and certain selling group members to bid for and purchase the Common Stock. As
an exception to these rules, the Underwriters are permitted to engage in certain
transactions that stabilize the price of the shares of Common Stock. Such
transactions consist of bids or purchases for the purpose of pegging, fixing or
maintaining the price of shares of Common Stock.
<PAGE>   295
 
                                                                [ALTERNATE PAGE]
 
     If the Underwriters create a short position in the Common Stock in
connection with the Offerings, i.e., if they sell more shares of Common Stock
than are set forth on the cover page of the Prospectus Supplement, the
Underwriters may reduce that short position by purchasing shares of Common Stock
in the open market. The Underwriters may also elect to reduce any short position
by exercising all or part of the over-allotment option described above.
 
     The Lead Managers may also impose a penalty bid on certain Underwriters and
selling group members. This means that if the Lead Managers purchase shares of
Common Stock in the open market to reduce the Underwriters' short position or to
stabilize the price of the shares of Common Stock, they may reclaim the amount
of the selling concession from the Underwriters and selling group members who
sold those shares as part of the Offerings.
 
     In general, purchases of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher than
it might be in the absence of such purchases. The imposition of a penalty bid
might also have an effect on the price of the Common Stock to the extent that it
discourages resales of the shares of Common Stock.
 
     Neither the Company nor any of the Underwriters makes any representation or
prediction as to the direction or magnitude of any effect that the transactions
described above may have on the price of the Common Stock. In addition, neither
the Company nor any of the Underwriters makes any representation that the
Underwriters will engage in such transactions or that such transactions, once
commenced, will not be discontinued without notice.
 
     Merrill Lynch, an affiliate of Merrill Lynch International, has from time
to time provided investment banking advisory services to the Company, for which
it has received customary compensation, and may continue to do so in the future.
Merrill Lynch has acted as financial advisor to the Company in connection with
the Merger, including serving as dealer manager with respect to the Tender
Offer. In this regard, the Company has agreed to indemnify Merrill Lynch against
certain liabilities. CIBC Oppenheimer Corp., Goldman, Sachs & Co. and Lehman
Brothers Inc. have from time to time provided investment banking or financial
advisory services to the Company, and may continue to do so in the future.

Pittsburgh, Pennsylvania. William R. Newlin, Chairman of the Board of the
Company, is a shareholder in Buchanan Ingersoll Professional Corporation. As of
          , Mr. Newlin owned        shares of Common Stock, stock credits

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Subchapter D of Chapter 17 of the Pennsylvania Business Corporation Law
(the "PBCL") provides in general that a corporation may indemnify any person,
including its directors, officers and employees who was or is a party or is
threatened to be made a party to any threatened, pending or completed action or
proceeding, whether civil, criminal, administrative or investigative (including
actions by or in the right of the corporation) by reason of the fact that he or
she is or was a representative of or serving at the request of the corporation,
against expenses (including attorney's fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by him or her in connection with
the action or proceedings if he or she is determined by the board of directors,
or in certain circumstances by independent legal counsel to the shareholders, to
have acted in good faith and in a manner he or she reasonably believed to be in,
or not opposed to, the best interests of the corporation and, with respect to
any criminal proceeding, had no reason to believe his conduct was unlawful. In
the case of actions by or in the right of the corporation, indemnification is
not permitted in respect of any claim, issue or matter as to which the person
has been adjudged to be liable to the corporation except to the extent a court
determines that the person is fairly and reasonably entitled to indemnification.
In any case, to the extent that the person has been successful on the merits or
otherwise in defense of any claim, issue or matter, he or she shall be
indemnified against expenses (including attorney's fees) actually and reasonably
incurred by him or her in connection therewith. Subchapter D also provides that
the indemnification permitted or required by Subchapter D is not exclusive of
any other rights to which a person seeking indemnification may be entitled.
 
     The Company's By-Laws provide that except as prohibited by law, every
director and officer of the Company is entitled to be indemnified by the Company
against reasonable expenses and any liability paid or incurred by such person in
connection with any actual or threatened claim, action, suit or proceeding,
civil, criminal, administrative, investigative or other in which he or she may
be involved by reason of being or having been a Director or Officer of the
Company or by reason that such person is or was serving at the request of the
Company as a director, officer, employee, fiduciary or other representative of
another corporation, partnership, joint venture, trust, employee benefit plan or
other entity. Such indemnification includes the right to have expenses incurred
paid in advance by the Company prior to final disposition, subject to such
conditions as may be prescribed by law. Persons who are not directors or
officers of the Company may be similarly indemnified in respect of service to
the Company or to another such entity at the request of the Company, to the
extent the Board of Directors designates. Expenses included fees and expenses of
counsel selected by such person, and liability includes amount of judgments,
excise taxes, fines and penalties, and amounts paid in settlement.
Indemnification pursuant to this provision of the Company's By-laws is not
permitted in any case in which the act or failure to act
 
                                      II-1
<PAGE>   298
 
giving rise to the claim for indemnification is determined by a court to have
constituted willful misconduct or recklessness. There may be other circumstances
where indemnification may not be permitted as a matter of public policy.
 
     The By-Laws of the Company also provide that to the fullest extent that the
laws of the Commonwealth of Pennsylvania, as now in effect or as hereafter
amended, permit elimination of limitation of the liability of directors, no
director of the Company shall be personally liable for monetary damages as such
for any action taken, or any failure to take any action, as a director. Under
Section 1713 of the PBCL, the personal liability of a director may not be
eliminated or limited if: (1) the director has breached or failed to perform the
duties of his office under Subchapter B of Chapter 17 of the PBCL (relating to
the fiduciary duties of directors); and (2) the breach or failure to perform
constitutes self-dealing, willful misconduct or recklessness. Furthermore, this
limitation to the personal liability of directors of the Company does not apply
to (1) the responsibility or liability of a director pursuant to any criminal
statute; or (2) the liability of a director for the payment of taxes pursuant to
local, state or federal law.
 
     The Company purchases director and officer liability insurance covering its
directors and officers with respect to liability which they may incur in
connection with their serving as such. Under the insurance, the Company will
receive reimbursement for amounts as to which the directors and officers are
indemnified under the Company's By-Laws. The insurance may also provide certain
additional coverage for the directors and officers against certain liability
even though such liability is not subject to indemnification under the Company's
By-Laws.

ITEM 17. UNDERTAKINGS
 
     (A) RULE 415 OFFERING.
 
     The undersigned registrants hereby undertake:
 
          (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 material information with respect to the plan of
        distribution not previously disclosed in the registration statement or
        any material change to such information in the registration statement;
 
          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at 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) FILINGS INCORPORATING SUBSEQUENT EXCHANGE ACT DOCUMENTS BY REFERENCE.
 
     The undersigned Registrants hereby undertake that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Company's annual report pursuant to Section 13(a) or 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.
 
                                      II-4
<PAGE>   301
 
     (C) EQUITY OFFERINGS OF NONREPORTING REGISTRANT.
 
     Kennametal Financing I hereby undertakes to provide to the underwriters at
the closing specified in the underwriting agreements certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.
 
     (H) REQUEST FOR ACCELERATION OF EFFECTIVE DATE.
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrants pursuant to the foregoing provisions, or otherwise, the Registrants
have been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrants of expenses
incurred or paid by a director, officer or controlling person of the Registrants
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 Registrants 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
a final adjudication of such issue.
 
     (I) REGISTRATION STATEMENTS PERMITTED BY RULE 430A.
 
     The undersigned Registrants hereby undertake that:
 
          (1) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of this Registration Statement in reliance upon Rule 430A and contained in
     the form of prospectus filed by the Registrant pursuant to Rule 424(b)(1)
     or (4) or 497(h) under the Securities Act shall be deemed to be part of
     this Registration Statement as of the time it was declared effective.
 
          (2) For the purpose of determining liability under the Securities Act
     of 1933, each post-effective amendment that contains a form of prospectus
     shall be deemed to be a new registration statement relating to the
     securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.
 
     (J) TRUST INDENTURE APPLICATION.
 
     The undersigned Registrants hereby undertake to file an application for the
purpose of determining the eligibility of the trustee to act under subsection
(a) of section 310 of the Trust Indenture Act ("Act") in accordance with the
rules and regulations prescribed by the Commission under section 305(b)(2) of
the Act.
