                          AMENDED AND RESTATED GUARANTY

THIS AMENDED AND RESTATED GUARANTY (this "Agreement"), dated as of June 20,
2003, is made by NS Group, Inc., a Kentucky corporation ("Parent"), Erlanger
Tubular Corporation, an Oklahoma corporation and a wholly-owned subsidiary of
Parent ("Erlanger"), and Northern Kentucky Management, Inc., a Kentucky
corporation and a wholly-owned subsidiary of Parent ("NK Management"; Parent,
Erlanger and NK Management are referred to herein individually as a "Guarantor"
and, collectively, as the "Guarantors"), in favor of The CIT Group/Business
Credit, Inc., a New York corporation, as agent for itself and the Lenders
referred to below ("Agent"). Capitalized terms used but not defined herein shall
have the meaning given to them in the Financing Agreement (as defined below).

                                    RECITALS

         A. Newport Steel Corporation, a Kentucky corporation ("Newport"), and
Koppel Steel Corporation, a Pennsylvania corporation ("Koppel"; Newport and
Koppel are referred to herein, individually, as a "Company" and, collectively,
as the "Companies") have entered into that certain Amendment No. 1 to Financing
and Security Agreement dated as of May 19, 2003 (the "Amendment") among Agent
and the lenders from time to time party thereto (the "Lenders"), and the
Companies, amending, upon the satisfaction of specified conditions, that certain
Financing and Security Agreement dated as of March 29, 2002 (the "Original
Financing Agreement"), among the Agent, the Lenders, and the Companies (the
Original Financing Agreement together with the Amendment, as the same may
hereafter be amended, restated, modified or otherwise supplemented from time to
time, is referred to herein as the "Financing Agreement").

         B. Each of Guarantors has executed and delivered to the Agent, for the
benefit of the Lenders, a guaranty dated as of March 29, 2002 (as amended,
restated, modified or otherwise supplemented from time to time, the "Existing
Guaranty") of all of the Obligations (as such term is defined in the Original
Financing Agreement).

         C. As a condition precedent to the effectiveness of the Amendment and
the further extension of credit to or for the account of the Companies in
connection therewith, the Secured Party and the Lenders require that Guarantors
amend and restate the Existing Guaranty in the form of this Guaranty.

         NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which hereby are acknowledged, the Existing Guaranty is amended
and restated in its entirety as follows:

         1.       Each Guarantor hereby, jointly and severally, unconditionally
guarantees and agrees to be liable for the full and indefeasible payment in
full, in cash and the performance when due of all Obligations owed by the
Companies to Agent and the Lenders. In addition to the Obligations, each

<PAGE>

Guarantor, jointly and severally, agrees to pay Agent on demand: (a) the amount
of all costs, fees and expenses (including reasonable attorney's fees) incurred
by Agent in connection with (i) the collection of any of the Obligations,
whether from any Company, any other obligor or Guarantor, and (ii) the
enforcement of Agent's and Lenders' rights against the Collateral (including the
costs, fees and expenses associated with the repossession, repair, maintenance,
liquidation, sale and foreclosure of or upon any Collateral); and (b) interest
at the default rate of interest under the Financing Agreement (not to exceed the
highest lawful rate) on all amounts payable to Agent and Lenders hereunder, even
if such interest cannot be collected from either Company because of the
application of any bankruptcy law or the ruling of any bankruptcy court. To the
extent Agent receives payment on account of any of the Obligations, which
payment is thereafter set aside or required to be repaid by Agent or the Lenders
in whole or in part, then, to the extent of any sum not finally retained by
Agent or the Lenders (regardless of whether such sum is recovered from Agent or
the Lenders by either Company, its trustee, or any other party acting for, on
behalf of or through either Company or its respective representatives), each
Guarantor's obligation to the Lenders under this Guaranty, as amended, modified
or supplemented, shall remain in full force and effect (or be reinstated) until
such Guarantor has made payment to Agent therefor, which payment shall be due
upon demand.

         2.       This Guaranty is executed by each Guarantor as an inducement
to the Lenders to extend credit to the Companies. Each Guarantor agrees that the
Lenders' extension of credit to the Companies shall be deemed to have been done
in consideration of and in reliance upon the execution of this Guaranty.

         3.       To the full extent permitted by applicable law, each Guarantor
hereby waives notice of (a) acceptance of this Guaranty, the making of loans or
advances to the Companies or the extension of any other financial accommodation
to the Companies under the Loan Documents, (b) the amendment, extension or
termination of the Promissory Notes or the amendment, modification, supplement,
renewal, restatement or extension of, or the increase or decrease in the amount
of, the Obligations or the Loan Documents and any Collateral, as applicable, and
the guaranty made herein shall apply to the Obligations as so amended, modified,
supplemented, renewed, restated, extended, increased or decreased, (c) any other
changes in terms of, or extensions of the time of payment of, the Obligations
owed by the Companies to the Lenders, (d) the taking and releasing of the
Collateral for, or other guarantors of, the Obligations owed by the Companies to
the Lenders, (e) the settlement, compromise or release of any of the Obligations
owed by the Companies to the Lenders, (f) any waiver of, or consent to either
Company's deviation from, any term, condition or covenant set forth in the Loan
Documents by Agent or the Lenders, and (g) presentment, demand, protest, notice
of protest, notice of non-payment and all other notices to which any Guarantor
may be entitled under applicable law (except as expressly provided in this
Guaranty), and each Guarantor agrees that the amount of the Obligations and the
validity and enforceability of this Guaranty shall not be diminished or affected
by the failure to provide such Guarantor with any such notice or by Agent's or
the Lenders' doing any of the foregoing. This Guaranty is a guaranty of payment
and performance and not merely a guaranty of collection, and accordingly each
Guarantor also agrees that neither Agent nor the Lenders need attempt to collect
any Obligations from the Companies or any other obligor or guarantor with
respect thereto, or to realize upon any Collateral, prior to making demand upon
any Guarantor under this Guaranty. This Guaranty is absolute, unconditional and
continuing,

                                       2

<PAGE>

regardless of the validity, regularity or enforceability of any of the
Obligations or Loan Documents or the fact that a security interest or lien in
any Collateral or security therefor may not be enforceable by Agent or the
Lenders or may otherwise be subject to equities, defenses or prior claims in
favor of others, or may be invalid or defective in any way and for any reason,
including any action, or failure to act, on Agent's or the Lenders' part. It is
the intent of each Guarantor by this paragraph to waive any to the full extent
permitted by applicable law, and all suretyship defenses available to such
Guarantor with respect to the Obligations, whether or not specifically
enumerated above.

         4.       Payment in cash by each Guarantor shall be made from time to
time on demand as Obligations become due to Agent, and one or more successive or
concurrent actions may be brought hereon against each Guarantor either in the
same action or in separate actions. In the event any claim or action based on
this Guaranty is made or brought against any Guarantor, such Guarantor agrees
not to assert against Agent or the Lenders any set-off or counterclaim which
either Company may have against Agent or the Lenders (other than the assertion
of a defense of payment), and further, each Guarantor agrees not to deduct,
set-off, or seek to counterclaim for or recoup, any amounts which are or may be
owed by Agent or the Lenders to any Guarantor, or for any loss of contribution
from any other guarantor. Each Guarantor hereby consents to the in personam
jurisdiction of the courts of the State of Illinois. In the event that Agent or
the Lenders bring any action or suit in any court of record in Illinois (whether
state or federal) to enforce any or all of the Obligations, service of process
may be made upon any Guarantor by mailing a copy of the summons to such
Guarantor at the address set forth below.

         5.       All sums at any time to the credit of any Guarantor and any
property of any Guarantor on which Agent at any time has a lien or security
interest, or of which Agent at any time has possession, shall secure payment and
performance of all Obligations and indebtedness of this Guaranty.

         6.       Upon the occurrence of any of the following events:

                  (a) any Event of Default under the Loan Documents; or

                  (b) the failure of any Guarantor to observe or perform any
         agreements, warranties or covenants contained herein;

then immediately, the liability of each Guarantor for the entire amount of the
Obligations shall mature, even if the liability of the Companies therefor does
not.

         7.       This Guaranty may be terminated by the Guarantors (or any one
of them) only upon actual receipt by Agent of at least thirty (30) days prior
written notice of termination sent by registered or certified mail; provided,
however, that the terminating Guarantor(s) shall remain bound hereunder, and
this Guaranty shall continue in full force and effect, with respect to any and
all Obligations created or arising prior to the effective date of such
termination and with respect to any and all extensions, renewals or
modifications of said pre-existing Obligations. Termination shall not

                                       3

<PAGE>

relieve any Guarantor from liability for any post-termination collection
expenses or interest which accrues hereunder.

         8.       Agent's books and records showing the Revolving Loan Account
shall be admissible in evidence in any action or proceeding as prima facie proof
of the items therein set forth. Agent's statements, if any, rendered to the
Companies shall be binding upon each Guarantor (whether or not such Guarantor
received copies thereof) and shall constitute an account stated between Agent
and the Companies unless Agent shall have received a written statement of the
Companies' exceptions in the manner provided in the Loan Documents.

         9.       Each Guarantor expressly waives any and all rights of
subrogation, reimbursement, indemnity, exoneration, contribution or any other
claim which it may now or hereafter have against either Company or any other
person directly or contingently liable for the Obligations, or against or with
respect to either Company's property (including, without limitation, property
securing the Obligations owed by the Company to Agent or the Lenders) arising
from the existence or performance of this Guaranty.

         10       This Guaranty embodies the whole agreement of the parties and
may not be modified except in writing, and no course of dealing between Agent or
the Lenders and the Guarantors shall be effective to change or modify this
Guaranty. Agent's or the Lenders' failure to exercise any right hereunder shall
not be construed as a waiver of the right to exercise the same or any other
right at any other time and from time to time thereafter, and such rights shall
be considered as cumulative rather than alternative. Agent's or any Lender's
knowledge of any breach or other nonobservance by any Guarantor of the terms and
provisions of this Guaranty shall not constitute a waiver thereof, nor a waiver
of any obligations to be performed by any Guarantor hereunder.

         11.      This Guaranty may be assigned by Agent and shall inure to the
benefit of Agent, on behalf of the Lenders, and for the benefit of any of
Agent's assignees or transferees, and shall cover all Obligations owed to the
Lenders and to Agent at the time of assignment or transfer as well as any and
all future Obligations under the Loan Documents owed by the Company to such
assignees or transferees. This Guaranty shall be binding jointly and severally
upon the Guarantors and their respective successors and assigns and shall
pertain to the Companies and their respective successors and assigns.

         12.      Anything contained in this Guaranty to the contrary
notwithstanding, the obligations of each Guarantor hereunder shall be limited to
a maximum aggregate amount equal to the greatest amount that would not render
such Guarantor's obligations hereunder subject to avoidance as a fraudulent
transfer or conveyance under Section 548 of Title 11 of the United States Code
or any provisions of applicable state law (collectively, the "Fraudulent
Conveyance Laws"), in each case after giving effect to all other liabilities of
such Guarantor, contingent or otherwise, that are relevant under the Fraudulent
Conveyance Laws (specifically excluding, however, any liabilities of such
Guarantor in respect of intercompany indebtedness to the Companies or affiliates
of the Companies to the extent such indebtedness would be discharged in an
amount equal to the amount paid by such Guarantor hereunder) and after giving
effect as assets to the value (as determined under the

                                       4

<PAGE>

applicable provisions of the Fraudulent Conveyance Laws) of any rights of
subrogation, contribution, reimbursement, indemnity or similar rights of such
Guarantor pursuant to applicable law or any agreement providing for an equitable
allocation among Guarantors and other Affiliates of the Companies of obligations
arising under guaranties by such parties.

         13.      After giving effect to the transactions contemplated by this
Guaranty and the other Loan Documents to which Erlanger or NK Management is a
party, (i) neither Erlanger or NK Management intends to incur or believes that
it will incur, debts beyond its ability to pay such debts as they become due,
and (ii) each of Erlanger and NK Management (a) owns and will own property, the
fair salable value of which is (1) greater that the total amount of its
liabilities (including contingent liabilities) and (2) greater than the amount
that will be required to pay the probable liabilities of its then existing debts
as they become absolute and matured, and (b) has and will have capital that is
not unreasonably small in relation to its business as presently conducted and as
proposed to be conducted.

         14.      THE OBLIGATIONS OF EACH GUARANTOR HEREUNDER ARE SECURED BY THE
SECURITY INTERESTS GRANTED BY SUCH GUARANTOR TO AGENT, FOR THE BENEFIT OF THE
LENDERS, PURSUANT TO THE SECURITY AGREEMENT (AS AMENDED, RESTATED, MODIFIED OR
OTHERWISE SUPPLEMENTED FROM TIME TO TIME) EXECUTED BY SUCH GUARANTOR IN FAVOR OF
AGENT, FOR THE BENEFIT OF THE LENDERS.

         15.      This instrument is executed and given in addition to, and not
in substitution, reduction, replacement, or satisfaction of, any other
endorsements or guarantees of the Obligations, now existing or hereafter
executed by the Guarantors or others in favor of Agent or the Lenders.

         16.      All notices, approvals, requests, demands and other
communications hereunder shall be given (i) if to a Guarantor, to such
Guarantor's address set forth on the signature page hereto and (ii) if to Agent,
to Agent's address set forth in the Financing Agreement, in each case in
accordance with the notice provisions of the Financing Agreement.

         17.      When used in this agreement, all pronouns shall, wherever
applicable, be deemed to include the singular and plural as well as the
masculine, feminine, and neuter genders.

         18.      Each Guarantor hereby acknowledges that it has received a copy
of the Loan Documents and is familiar with the terms and provisions thereof.

         19.      This Guaranty shall be governed by and construed in accordance
with the internal laws of the State of Illinois, without regard for its conflict
of law principles.

         20.      EACH OF THE GUARANTORS, AGENT AND THE LENDERS HEREBY WAIVES
ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING ARISING OUT OF THIS
GUARANTY.

                                       5

<PAGE>

         21.      The Existing Guaranty is amended and restated in its entirety
in the form hereof; provided, however, that any representation and warranties
made by such Guarantor to the Agent and the Lenders (as defined in the Existing
Guaranty) shall survive the execution and delivery hereof.
