ITEM 2.     ACQUISITION OR DISPOSITION OF ASSETS.

            On April 18, 1997, Quanex Corporation, a Delaware corporation (the
            "Company"), completed the sale of LaSalle Steel Company
            ("LaSalle"), a Delaware corporation and wholly owned subsidiary of
            the Company, to Niagara Cold Drawn Corp., a Delaware corporation
            and wholly owned subsidiary of Niagara Corporation, pursuant to the
            Stock Purchase Agreement dated as of April 18, 1997 (the
            "Agreement").  Under the terms of the Agreement, the Company
            received cash consideration of approximately $65 million, subject
            to post closing adjustment.

            The disposition of LaSalle was structured as a sale of all of the
            capital stock of LaSalle.  The principle followed in fixing the
            purchase price for LaSalle under the Agreement was based on
            negotiations between the parties.

            A copy of the press release announcing the closing of the Agreement
            is filed as Exhibit 99.1 and is hereby incorporated herein by
            reference.



ITEM 7.     FINANCIAL STATEMENTS AND EXHIBITS.

            (a)  Financial Statements of Business Acquired.

            Not applicable.

            (b)  Pro Forma Financial Information.

            The following unaudited pro forma consolidated statements of income
            for the year ended October 31, 1996 and the three months ended
            January 31, 1997 give effect to the disposition of LaSalle as if
            the sale and the resulting debt reduction occurred on November 1,
            1995 and November 1, 1996, respectively.  The following unaudited
            pro forma consolidated balance sheet as of January 31, 1997 gives
            effect to the disposition of LaSalle as if the sale and the
            reduction of long-term debt with the net proceeds thereof occurred
            as of that date.

            The pro forma financial information does not purport to be
            indicative of either a)  the results of operations which would have
            actually been obtained if the disposition had occurred on the dates
            indicated, or b) the results of operations which will be reported
            in the future.

            The pro forma income statements do not reflect the anticipated gain
            on the sale of LaSalle.  Quanex treated LaSalle as a discontinued
            operation and, accordingly, the gain is not part of the pro forma
            requirements.

 For the Year Ended October 31, 1996 and the Three Months Ended January 31, 1997
                                  (Unaudited)


Balance Sheet

The pro forma adjustments to the consolidated balance sheet as of January
31, 1997 reflect the following:

a)       Record accounts receivable from LaSalle  Steel Company ("LaSalle")
         which previously was eliminated in consolidation.

b)       The disposition of LaSalle for $65.5 million, net of transaction 
         costs of $1.6 million, and the resulting reduction of debt of 
         $63.9 million.

c)       The recognition of anticipated gain from the sale and related income
         taxes.



Income Statement

The pro forma adjustments to the consolidated statements of income reflect
the following:

a)       The elimination of LaSalle operations for the year ended October 31,
         1996.

b)       The decrease in interest expense for the year ended October 31, 1996,
         resulting from the debt repayment of $63.9 million, reduced by
         estimated quarterly payment of income taxes related to the gain on
         sale, at an interest rate of 6.3%.  The decrease in interest expense
         for the three months ended January 31, 1997, resulting from the debt
         repayment of $63.9 million at an interest rate of 6.4%.

c)       The tax effect of pro forma adjustments at the Company's effective
         rate of 42% for the year ended October 31, 1996 and 35% for the three

         Sheet"), together with the related audited statements of (i) income
         and retained earnings and (ii) cash flows, each for the period
         November 1, 1996 through the Closing Financial Statement Date
         (collectively with the Closing Balance Sheet, once finalized and
         binding in accordance with this Section 1.7, the "Closing Financial
         Statements"), prepared (i) from the books and records of the Company,
         (ii) in accordance with generally accepted accounting principles
         applicable to a fiscal year end ("GAAP"), (iii) on a basis consistent
         with (x) the audited balance sheet of the Company as at October 31,
         1996 (the "1996 Balance Sheet") and the related audited statements of
         (A) income and retained earnings and (B) cash flows, each for the
         fiscal year then ended and (y) the unaudited balance sheet of the
         Company as at January 31, 1997, and the related unaudited statements
         of (A) income and retained earnings and (B) cash flows, each for the

         Balance Sheet and without reflecting any adjustment for settlements,
         curtailments or business combinations relating to the sale of the
         Shares to the Buyer pursuant to this Agreement and (v) fairly
         presenting the financial condition and results of operations of the
         Company as of the Closing Financial Statement Date and for the portion
         of the fiscal year then ending; provided,however, that the Closing
         Balance Sheet (which shall be prepared in accordance with GAAP) shall
         not reflect any reserves, provisions, or accruals for any Taxes (other
         than deferred income Taxes) relating to any consolidated federal
         income Tax Returns or any consolidated, combined, affiliated or
         unitary state, local or foreign income Tax Returns (including, but not
         limited to, Indiana Corporation Income Tax Returns filed on a combined
         basis) which include the Company, including, but not limited to, such
         reserves, provisions or accruals for "Income Taxes Payable to Parent"
         (which the Parties acknowledge and agree will be subtracted from any
         intercompany receivable to the Company from the Seller or added to any
         intercompany payable by the Company to the Seller, as the case may be,
         in connection with the preparation and finalization of the Closing
         Balance Sheet).  The costs and expenses incurred in connection with
         the preparation and delivery of the Closing Financial Statements shall
         be borne by the Seller.

                 (b)      From time to time following the Closing and until the
         Closing Financial Statements have been finalized in accordance with
         this Section 1.7, Niagara and the Buyer on the one hand, and the
         Seller on the other hand, shall give each other, and any of its or
         their independent accountants and authorized representatives,
         reasonable access during normal business hours to the properties,
         books, records and personnel of the Seller and the Company, and shall
         use its or their reasonable best efforts (which shall not be deemed to
         require the Seller to make any unreasonable expenditures) to cause the
         Company's independent accountants to make available to each such
         Party, and its or their authorized representatives, their work papers
         generated in connection with their





                                       3
<PAGE>   7
         review and audit of the Company's financial statements, in each case
         relating to periods ending on or prior to the Closing Date, for
         purposes of preparing, reviewing and resolving any disputes concerning
         the Closing Financial Statements.  All such information and access
         shall be conducted in a manner which does not unreasonably interfere
         with such other Party's business and operations and shall be subject
         to the provisions of Section 4.4(a) hereof.

                 (c)      Niagara and the Buyer shall have 45 days following
         delivery of the financial statements referred to in Section 1.7(a)
         hereof during which to submit to the Seller, in accordance with
         Section 7.9 hereof, a written statement (a "Buyer's Statement")
         setting forth any disputed item (and shall provide, in reasonable
         detail, the basis for such dispute) in such financial statements.  In
         this regard, it is understood and agreed that Niagara and the Buyer
         may themselves prepare financial statements of the Company as of the
         Closing Date and for the portion of the fiscal year then ended or
         submit specific changes to the financial statements delivered by the
         Seller to Niagara and the Buyer  pursuant to Section 1.7(a) hereof.
         The Seller shall cooperate with Niagara and the Buyer as reasonably
         requested in the preparation of any such financial statements.  The
         costs and expenses incurred in connection with the preparation and
         delivery of a Buyer's Statement shall be borne by the Buyer.  If
         Niagara and the Buyer fail to submit a Buyer's Statement within such
         45-day period, then the financial statements delivered by the Seller
         to Niagara and the Buyer pursuant to Section 1.7(a) hereof shall be
         deemed the Closing Financial Statements.

                 (d)      In the event Niagara and the Buyer deliver to the
         Seller a Buyer's Statement, the Parties shall consult and attempt to
         resolve, as soon as practicable, all disputes set forth therein.  In
         the event the Parties are unable to resolve any such dispute within 30
         days of the delivery of the Buyer's Statement, such disputes shall be
         resolved by Arthur Andersen & Co. (the "Independent Accounting Firm").
         If, for any reason, Arthur Andersen & Co. cannot serve as the
         Independent Accounting Firm or declines to so serve, then such dispute
         shall be resolved by Coopers & Lybrand and such accounting firm shall
         be the Independent Accounting Firm for purposes of this Agreement.
         If, for any reason, Coopers & Lybrand cannot serve as the Independent
         Accounting Firm or declines to so serve, then such disputes shall be
         resolved by KPMG Peat Marwick and such accounting firm shall be the
         Independent Accounting Firm for purposes of this Agreement.  The
         Independent Accounting Firm shall be instructed to make its
         determination as promptly as practicable and such determination shall
         be final and binding upon the Parties enforceable by appropriate
         judicial proceedings.  The fees and expenses of the Independent
         Accounting Firm in performing such function shall be shared equally by
         Niagara or the Buyer, on the one hand, and the Seller, on the other
         hand.  The financial statements delivered by the Seller to Niagara and
         the Buyer pursuant to Section 1.7(a) hereof, as modified to reflect
         the resolution of disputes by the Parties or by the Independent
         Accounting Firm in accordance with this Section 1.7, shall be the
         "Closing Financial Statements."

                 (e)      On the tenth business day following the delivery of
         the Closing Financial Statements (the "Adjustment Date") either (i)
         the Buyer shall pay to the Seller the difference between the Purchase
         Price (as defined below) and the Estimated Purchase Price, if the
         Purchase Price exceeds the Estimated Purchase Price or (ii) the Seller
         shall pay to the Buyer the difference between the Purchase Price and
         the Estimated Purchase Price, if the Estimated Purchase Price exceeds
         the Purchase Price, in either case by interbank or wire transfer of
         immediately available funds to an account designated in writing by the
         recipient of such payment at least two business days prior to the
         Adjustment Date.  In this regard, it is understood and agreed that any
         payable to or receivable from the Seller as of the Closing Financial
         Statement Date shall be cancelled without any payment by one Party to
         another Party in respect thereof.  For purposes of this Agreement, (i)
         "Purchase Price" shall mean the sum of (x) $58,862,000 and (y) Total
         Equity (as defined below) reduced by Estimated Total Equity (as
         defined below); (ii) "Total Equity" shall mean the sum of (x) total
         stockholder's equity stated on the Closing Balance Sheet and (y) the
         amount of any intercompany payable from the Company to the Seller
         stated on the Closing Balance Sheet reduced by the amount of any
         intercompany receivable of the Company from the Seller stated on the
         Closing Balance Sheet and (iii) "Estimated Total Equity" shall mean
         $4,709,000, which is the total stockholder's equity stated on the 1996
         Balance Sheet reduced by the amount of the intercompany receivable due
         the Company from the Seller (other than in respect of Taxes) stated on
         the 1996 Balance Sheet.

                 (f)      The rights to indemnification in favor of any Buyer
         Indemnified Party (as defined in Section 6.3 hereof) pursuant to
         Section 6.3(i) hereof (and any limitations on such rights) shall not
         be deemed to limit,





                                       4
<PAGE>   8
         supersede or otherwise affect the rights of the Buyer and the Seller
         for a full purchase price adjustment pursuant to this Section 1.7,
         provided that no claim for indemnification may be made pursuant to
         Section 6.3(i) hereof with respect to any Losses (as defined in
         Section 6.3 hereof) to the extent that such Losses are included as a
         liability on the Closing Balance Sheet.

                 (g)      Within two business days of the Closing Date, the
         Seller shall deliver to Niagara and the Buyer, by overnight delivery
         (Federal Express) to the addresses set forth in Section 7.9 hereof, a
         statement (the "Intercompany Statement") of the results of the cash
         activity in the intercompany account between the Seller and the
         Company (taking into account (i) cash transfers to and from the Seller
         and (ii) non-cash billings from the Seller only to the extent that
         such billings result from cash disbursements made by the Seller on
         behalf of the Company) from (but not including) the Closing Financial
         Statement Date through (and including) the Closing Date (the "Interim
         Period"), together with appropriate supporting documentation
         (including any such supporting documentation that Niagara or the Buyer
         may reasonably request).  Within seven business days of the Closing
         Date, and notwithstanding the delivery of a Buyer's Intercompany
         Statement (as defined below), the Buyer shall pay to the Seller, or
         the Seller shall pay to the Buyer, the amount of the intercompany
         payable in respect of such activity as set forth on such statement
         (the "Intercompany Payment"), in either case by interbank or wire
         transfer of immediately available funds to an account designated in
         writing by the recipient of such payment at least one business day
         prior to such date.  From and after the Closing, the Seller shall
         promptly deliver all funds and mail of any kind or form relating to
         the Business or the Company to the Company's administrative offices in
         Hammond, Indiana.  Niagara and the Buyer shall have 30 days following
         delivery of the Intercompany Statement during which to submit to the
         Seller, in accordance with Section 7.9 hereof, a written statement (a
         "Buyer's Intercompany Statement") setting forth any disputed item (and
         shall provide, in reasonable detail, the basis for such dispute) in
         the Intercompany Statement.  In the event Niagara and the Buyer
         deliver to the Seller a Buyer's Intercompany Statement, the Parties
         shall consult and attempt to resolve, as soon as practicable, all
         disputes set forth therein.  In the event the Parties are unable to
         resolve any such dispute within 15 days of the delivery of a Buyer's
         Intercompany Statement, such disputes shall be resolved by the
         Independent Accounting Firm.  The Independent Accounting Firm shall be
         instructed to make its determination as promptly as practicable and
         such determination shall be final and binding upon the Parties
         enforceable by appropriate judicial proceedings.  The fees and
         expenses of the Independent Accounting Firm in performing such
         function shall be shared equally by Niagara or the Buyer, on the one
         hand, and the Seller, on the other hand.  On the fifth business day
         following the resolution of all disputes set forth in the Buyer's
         Intercompany Statement (either by the Parties or by the Independent
         Accounting Firm) in accordance with this Section 1.7(g), the Buyer or
         the Seller, as the case may be, shall make a payment to the other in
         an amount that reflects the resolution of all such disputes.  Such
         payment shall be made by interbank or wire transfer of immediately
         available funds to an account designated in writing by the recipient
         of such payment at least two business days prior to such payment date.

         tangible personal property of the Company are in good and normal
         operating condition and repair (ordinary wear and tear excepted).

         2.13  Certain Contracts.  Schedule 2.13(a) of the Disclosure Schedule

and all amendments and other modifications thereto, have been delivered to or
been made available for inspection by Niagara and the Buyer.  All Material
Contracts (x) are valid and binding obligations of the Company and, to the
knowledge of those Persons identified on Schedule 2.13(b) of the Disclosure
Schedule, the other parties thereto, (y) are in full force and effect and are
enforceable as to the Company and, to the knowledge of those Persons identified
on Schedule 2.13(c) of the Disclosure Schedule, the other parties thereto, in
accordance with their respective terms and (z) except for any Material Contract
that is a Designated Plan, have not been amended or terminated except in the
ordinary course of business consistent with past practice.  The Company is not
in default under nor has it breached in any respect any Material Contract.  No
other party to any Material Contract (i) has, to the knowledge of those Persons

default thereunder, (ii) has given notice that it intends to terminate such
Material Contract or (iii) has altered, in any way adverse to the Company, its
performance under such Material Contract.  No event or condition has occurred
(or is alleged by any other party to a Material Contract to have occurred)
which, with or without due notice or lapse of time or both, would constitute, a
breach or event of default on the part of the Company, would provide a basis
for a valid claim or acceleration under any Material Contract as against the
Company or would prevent the Company from exercising and obtaining the full
benefits of any rights or options contained therein.  For purposes of this
Agreement, "Contracts" shall mean and include all leases, contracts,
agreements, license agreements, purchase orders, invoices, sales orders,
instruments evidencing indebtedness for borrowed money, mortgages or other
documents securing any indebtedness for borrowed money, commitments and
understandings, written or oral, and all amendments or modifications thereto,
to which the Company is a party or by which the Company, or any of the
Company's business, properties or assets, is bound; and "Material Contracts"
shall mean and include all (a) Contracts evidencing or relating to indebtedness
for borrowed money, (b) Contracts relating to the Real Property, (c) Contracts
for the development of the Intellectual Property, the license agreements set
forth on Schedule 2.19(b) of the Disclosure Schedule and assignments of any
Intellectual Property, (d) leases of personal property by or to the Company
involving monetary obligations of more than $25,000 per year, (e) purchase or
supply Contracts with terms extending for a period of more than three months
involving monetary obligations by or to the Company of more than $25,000 per
year  ( but specifically excluding the informal arrangement identified on
Schedule 2.13(a)-1 of the Disclosure Schedule), (f) Contracts with any other
direct or indirect subsidiary of the Seller providing for payments in excess of
$25,000 or Contracts with any Seller's Affiliate other than such subsidiaries,

$25,000 per year and (i) Contracts which otherwise are material to the
Business.

         2.14  Compliance with Laws and Permits.  (a)  The Business has been
conducted and is now being conducted in all material respects in compliance
with all Laws and orders, judgments, injunctions, awards, decrees, writs and
similar actions ("Orders") of all Governmental Authorities having jurisdiction
over the Company and all franchises, licenses, certificates, registrations,
permits, authorizations, approvals of, and any required registration with, all
Governmental Authorities ("Permits") relating to any of its properties or
applicable to the Business.

                 (b)      To the knowledge of those Persons identified on
         Schedule 2.14(a) of the Disclosure Schedule, the Company possesses all
         Permits necessary to own and operate its properties and assets and to
         conduct its business as it is currently conducted.  To the knowledge
         of those Persons identified on Schedule 2.14(b) of the Disclosure
         Schedule, such Permits are valid, subsisting and in full force and
         effect, and the Company has fulfilled its obligations under each of
         such Permits, and no event has occurred or condition or state of facts
         exists which constitutes or, after notice or lapse of time or both,
         would constitute, a default or violation under any of such Permits or
         would permit revocation or termination of any of such Permits.  In
         respect of any such Permits, no proceeding is pending for which notice
         has been provided to the Company or the Seller or, to the knowledge of
         those Persons identified on Schedule 2.14(c) of the Disclosure
         Schedule, threatened, looking toward revocation or termination of any
         such Permits.

         2.15  Litigation and Arbitration.  (a)  Neither the Company nor the
Seller is subject to any Order affecting the Company or the Business.  Neither
the Company nor, with respect to the Company, the Seller, is a party to, is
bound by, or has any obligation under any settlement agreement affecting the
Business or any agreement, waiver or Consent tolling any statute of
limitations.  Except as and to the extent set forth on Schedule 2.15(a) of the
Disclosure Schedule and except for workers compensation claims, there are no
claims, actions, causes of action, suits, proceedings, inquiries or

Business, and no such claim, action, suit, inquiry, proceeding or investigation
has been pending (for which notice was provided to the Seller or the Company)
during the three-year period preceding the date hereof except as and to the
extent set forth on Schedule 2.15(c) of the Disclosure Schedule.  Schedule
2.15(d) of the Disclosure Schedule sets forth a complete and correct list of
all workers compensation claims in excess of $10,000 brought by employees of
the Company during the three years prior to the date hereof, together with the
amount of all workers compensation claims brought by employees of the Company
for each such year.  None of the Persons identified on Schedule 2.15(e) of the
Disclosure Schedule has knowledge of any fact or circumstance which could
reasonably be expected to result in any other claim, action, cause of action,
suit, proceeding, inquiry, investigation or Order against the Company or the
Business.

                 (b)      No claim, action, suit, proceeding, inquiry or
         investigation set forth on Schedules 2.15(a) or (d) of the Disclosure
         Schedule, individually or in the aggregate, if adversely decided,
         could have a material adverse affect on the Company or the Business or
         prevent the consummation of the transactions contemplated by this
         Agreement or the Other Documents executed and delivered pursuant
         hereto or in connection herewith.

including, without limitation, plans that provide retirement income or result
in a deferral of income by employees for periods extending to termination of
employment or beyond, and plans that provide medical, surgical, or hospital

employment contracts, retention incentive agreements, non-competition

currently in effect or were maintained within three years of the date hereof,
or have been approved before this date but are not yet effective, for the
benefit of directors, officers, employees or former employees (or their
beneficiaries) of the Company (Plans and Benefit Arrangements being
collectively referred to herein as "Designated Plans").  Schedule 2.16(a) of
the Disclosure Schedule identifies each of the Plans that is subject to Section
302 or Title IV of ERISA or Section 412 of the Code.

                 (b)      With respect to each Designated Plan, the Seller or
         the Company has heretofore delivered to Niagara and the Buyer,
         complete and correct copies of each of the following documents:

                          (i)     the Designated Plan and any amendments

                 the Designated Plan;

                          (vii)   the most recent financial statement; and

                 of the Code.

<PAGE>   16
                 (c)      No asset of the Company, or any entity (whether or
         not incorporated) that is treated as a single employer together with
         the Company under Section 414 of the Code (an "ERISA Affiliate"), is
         the subject of any lien arising under Section 302(f) of ERISA or
         Section 412(n) of the Code; no Company or ERISA Affiliate has been
         required to post any security under Section 307 of ERISA or Section
         401(a)(29) of the Code; and no fact or event exists that could
         reasonably be expected to give rise to any such lien or requirement to
         post any such security.

                 (d)      The Pension Benefit Guaranty Corporation ("PBGC") has
         not instituted proceedings to terminate any pension benefit plan as
         defined in Section 3(1) of ERISA that is maintained or contributed to
         by the Company or any ERISA Affiliate and no condition exists that
         presents a material risk that such proceedings will be instituted.

                 (e)      Except as and to the extent set forth on Schedule
         2.16(b) of the Disclosure Schedule, no pension benefit plan as defined
         in Section 3(1) of ERISA that is maintained or contributed to by the
         Company or any ERISA Affiliate had an accumulated funding deficiency
         as defined in Section 302 of ERISA and Section 412 of the Code,
         whether or not waived, as of the last day of the most recent fiscal
         year of the Plan ending on or prior to the Closing Date.  All
         contributions required to be made with respect to any Plan on or prior
         to the Closing Date have been timely made or will be reflected on the
         Closing Balance Sheet.

                 (f)       Neither the Company nor any entity that was at any
         time during the six-year period ending on the date hereof an ERISA
         Affiliate has ever maintained, had an obligation to contribute to,
         contributed to, or incurred any liability with respect to a plan that
         is both a multiemployer plan (as defined in Section 3(37) of ERISA)
         and a pension benefit plan (as defined in Section 3(1) of ERISA) or a
         plan described in Section 4063(a) of ERISA.

                 (g)      To the knowledge of the Seller and the Company,
         neither the Company nor any other entity has engaged in a transaction
         that could reasonably be expected to result in the imposition upon the
         Company of a civil penalty under Section 409 or 502(i) of ERISA or a
         tax under Section 4975 or 4976 of the Code with respect to any
         Designated Plan.

                 (h)      Each Designated Plan has been operated and
         administered in all material respects in accordance with its terms and
         applicable Law, including but not limited to ERISA and the Code.

                 (i)      The terms of all Designated Plans that are intended
         to qualify under Section 401(a) of the Code (i) have been determined
         by the IRS to qualify under Section 401(a) of the Code or (ii) of the
         applicable remedial amendment periods under Section 401(b) of the Code
         will not have expired prior to the Closing Date.  The Seller and the
         Company have no knowledge of any event or circumstance that could
         reasonably be expected to cause the IRS to disqualify any Designated
         Plan that is intended to qualify under Section 401(a) of the Code.  To
         the knowledge of the Seller and the Company, each Designated Plan that
         is intended to satisfy the requirements of Section 501(c)(9) of the
         Code has satisfied such requirements.

                 (j)      Schedule 2.16(a) of the Disclosure Schedule
         identifies each Designated Plan that provides medical, surgical,
         hospitalization, or life insurance benefits (whether or not insured by
         a third party) for employees or former employees of the Company for
         periods extending beyond their retirements or other terminations of
         service, other than (i) coverage mandated by applicable Law, (ii)
         death benefits under any pension benefit plan as defined in Section
         3(1) of ERISA, or (iii) benefits the full cost of which is borne by
         the current or former employee (or his beneficiary).

                 (k)      Except as and to the extent set forth on Schedule
         2.16(c) of the Disclosure Schedule, the consummation of the
         transactions contemplated by this Agreement and the Other Documents,
         either alone or in conjunction with another event (such as a
         termination of employment), will not (i) entitle any current or former
         employee or officer of the Company, to severance pay, or any other
         payment under a Designated Plan, (ii) accelerate the time of payment
         or vesting of benefits under a Designated Plan or (iii) increase the
         amount of compensation due any such employee or officer.

                 (l)      There is no litigation, action, proceeding, or claim
         pending, or to the knowledge of the Seller and the Company, threatened
         or contemplated relating to any Designated Plan (other than routine
         claims for benefits).

                 (m)      Except as and to the extent set forth on Schedule
         2.16(d) of the Disclosure Schedule, neither the Company nor any entity
         that was at any time during the six-year period ending on the date
         hereof an ERISA Affiliate has incurred any liability under Title IV of
         ERISA that has not been satisfied in full (other than liability to the
         PBGC for the payment of premiums pursuant to Section 4007 of ERISA).
         No condition exists for which the PBGC is authorized to seek from the
         Company or an ERISA Affiliate a late payment charge under Section
         4007(b) of ERISA.  Except as and to the extent set forth on Schedule
         2.16(e) of the Disclosure Schedule, no condition exists that presents
         a risk that the Company or an ERISA Affiliate will incur any liability
         under Title IV of ERISA (other than liability to the PBGC for the
         payment of premiums pursuant to Section 4007 of ERISA).

                 (n)      During the six-year period ending on the day before
         the Closing Date, no "reportable event" within the meaning of Section
         4043(c) of ERISA with respect to which the 30-day notice requirement
         has not been waived by the PBGC has occurred with respect to the
         LaSalle Steel Company Pension Plan for Hourly Employees.

         the Disclosure Schedule, as of the date prior to the date hereof,
         neither the Company nor the Seller has received notification that any
         of the current employees of the Company presently plans to terminate
         his or her employment during the 1997 calendar year, whether by reason
         of the transactions contemplated by this Agreement (and the Other
         Documents) or otherwise.

         relationship.

                 (c)      During the last four years, the Company has not
         effectuated (i) a "plant closing" (as defined in the Worker Adjustment
         Retraining Notification Act of 1988 (the "WARN Act")) affecting any

                              ADDITIONAL COVENANTS

         4.1  Benefit Matters.

                 (a)      Salaried Pension Plan.

                 (i)      As soon as practicable following the determination of
         the Permitted Transfer Amount (as defined below) in accordance with
         Section 4.1(a)(ii) hereof, the Seller shall direct the trustee of the
         Quanex Corporation Salaried Employees' Pension Plan to transfer, in
         cash, from the trust maintained under the Quanex Corporation Salaried
         Employees' Pension Plan to the trust maintained under the LaSalle
         Steel Company Salaried Employees' Pension Plan (the "Buyer Salaried
         Pension Plan"), an amount equal to the amount required to be
         transferred pursuant to Section 414(1) of the Code (determined as of
         the Closing Date) with respect to current and former employees of the
         Company set forth on Schedule 4.1(a) of the Disclosure Schedule (the
         "Salaried Participants") and their beneficiaries calculated utilizing
         such actuarial assumptions as are agreed upon by the enrolled
         actuaries for the Quanex Corporation Salaried Employees' Pension Plan
         and the Buyer Salaried Pension Plan, which agreement shall not be
         withheld unreasonably  (the "Permitted Transfer Amount"), provided,
         however, that to the extent permitted by Section 414(1) of the Code,
         the Permitted Transfer Amount shall be equal to $6,709,000 adjusted
         for (i) contributions reflected on the Closing Balance Sheet and
         benefit distributions made to the Salaried Participants and their
         beneficiaries during the period (the "Adjustment Period") commencing
         on October 31, 1996 and ending on the date on which the transfer
         occurs (the "Transfer Date") and (ii) a pro rata share of the Quanex
         Corporation Salaried Employees' Pension Plan actual investment
         earnings or losses occurring during the Adjustment Period and Plan
         administrative expenses actually paid from the Quanex Corporation
         Salaried Employees' Pension Plan during the Adjustment Period (the
         "Fixed Transfer Amount"); provided, further, that (i) if the Permitted
         Transfer Amount is less than the Fixed Transfer Amount, then the
         Permitted Transfer Amount shall be transferred from trust to trust,
         and the Seller shall pay to the Buyer, in cash on the Transfer Date,
         the excess of the Fixed Transfer Amount over the Permitted Transfer
         Amount and (ii) if the Permitted Transfer Amount exceeds the Fixed
         Transfer Amount, then the Permitted Transfer Amount shall be
         transferred trust to trust, and the Buyer shall pay to the Seller, in
         cash on the Transfer Date, the excess of the Permitted Transfer Amount
         over the Fixed Transfer Amount.

                 (ii)     The Seller shall deliver to Niagara and the Buyer (in
         accordance with the provisions of Section 7.9 hereof) as soon as
         reasonably practicable, and in any event within 60 days of the Closing
         Date, a statement setting forth the proposed Fixed Transfer Amount and
         Permitted Transfer Amount (collectively, the "Transfer Amounts") as
         certified by the Seller's actuaries (the "Seller's Transfer Amount
         Statement").  The costs and expenses incurred in connection with the
         preparation and delivery of the Seller's Transfer Amount Statement
         shall be borne by the Seller.  Niagara and the Buyer shall have 45
         days following the delivery of the Seller's Transfer Amount Statement
         during which to submit to the Seller, in accordance with the
         provisions of Section 7.9 hereof, a written statement setting forth
         any dispute therewith (a "Buyer's Transfer Amount Statement").  The
         costs and expenses incurred in connection with the preparation of a
         Buyer's Transfer Amount Statement shall be borne by the Buyer.  If
         Niagara and the Buyer fail to submit a Buyer's Transfer Amount
         Statement within such 45-day period, then the proposed Transfer
         Amounts set forth on the Seller's Transfer Amount Statement, as
         further adjusted in accordance with Section 4.1(a) hereof, shall be
         deemed the Transfer Amounts.  In the event Niagara and the Buyer
         deliver a Buyer's Transfer Amount Statement, the Parties shall consult
         and attempt to resolve, as soon as practicable, all disputes set forth
         therein.  In the event the Parties are unable to resolve any such
         dispute within 30 days of the delivery of the Buyer's Transfer Amount
         Statement, such dispute shall be resolved by a nationally recognized
         independent actuarial firm mutually acceptable to the Parties (the
         "Independent Actuarial Firm").  The Independent Actuarial Firm shall
         be instructed to make its determination as promptly as practicable and
         such determination shall be final and binding upon the Parties
         enforceable by appropriate judicial proceedings.  The fees and
         expenses of the Independent Actuarial Firm shall be shared equally by
         the Buyer and the Seller.  The proposed Transfer Amounts set forth in
         the Seller's Transfer Amount Statement, as modified to reflect the
         resolution of disputes by the Parties or by the Independent Actuarial
         Firm in accordance with this Section 4.1, shall be the "Transfer
         Amounts".

                 (iii)    From time to time during the Adjustment Period,
         Niagara and the Buyer on the one hand, and the Seller on the other
         hand, shall give the other, and any of its or their independent
         actuaries and authorized representatives, reasonable access during
         normal business hours to the properties, books, records and personnel
         of the Seller and the Company, and shall use all reasonable efforts to
         cause their independent actuaries to make available to each such other
         Party and its or their authorized representatives their work papers
         generated in connection with the preparation of the Seller's Transfer
         Amount Statement and any Buyer's Transfer Amount Statement for
         purposes of resolving any disputes concerning the Transfer Amounts.

                 (iv)     As soon as reasonably practicable, the Parties shall
         cooperate with each other in making any required filings, including
         Forms 5310-A (with all attachments), reflecting the transfer of assets
         and assumption of liabilities pursuant to this Section 4.1(a).  In
         connection and concurrent with such transfer, the liabilities under
         the Quanex Corporation Salaried Employees' Pension Plan in respect of
         the Salaried Participants shall be transferred to the Buyer Salaried
         Pension Plan.

                 (b)      Savings Plans.  As soon as reasonably practicable,
         and in any event within 90 days of the Closing Date, each participant
         in the Quanex Corporation Employee Savings Plan or the Quanex
         Corporation Hourly Bargaining Unit Employee Savings Plan
         (collectively, the "Seller Savings Plans") who is an employee or
         former employee of the Company shall have the right to elect to
         receive a distribution of all or a portion of such employee's account
         balance in the applicable Seller Savings Plan (subject to, and in
         accordance with, the provisions of the respective plan and applicable
         Law).  The Buyer shall take any and all necessary action to cause the
         trustee of the Niagara Cold Drawn 401(k) Retirement Plan (the "Buyer
         Savings Plan"), if requested to do so by a distributee, to accept the
         "roll over" of all or a portion of any such distribution from the
         applicable Seller Savings Plan.

                 (c)      Group Benefits Plan.  The Buyer hereby assumes all
         liabilities under the Quanex Corporation Group Benefits Plan for all
         participants who are employees or former employees of the Company, as
         set forth on Schedule 4.1(b) of the Disclosure Schedule, and their
         dependents, as of the Closing Date (the "LaSalle Group Benefit Plan
         Participants") subject to the terms and conditions of such plan.
         Effective as of the Closing, the Seller shall (i) cause the Company to
         terminate its participation as an adopting employer with respect to
         the Quanex Corporation Group Benefits Plan and (ii) cause that portion
         of the Quanex Corporation Group Benefit Plan covering the LaSalle
         Group Benefits Plan Participants to be spun-off into a new welfare
         benefit plan entitled the "LaSalle Steel Company Group Benefits Plan"
         which shall be sponsored by the Company and which, as of the Closing,
         shall otherwise be substantially identical to the Quanex Corporation
         Group Benefits Plan.

                 (d)      Deferred Compensation Plan.  Effective as of the
         Closing, the Seller shall cause the Company to terminate its
         participation as an adopting employer with respect to the Quanex
         Corporation Deferred Compensation Plan maintained for the benefit of
         current and former key salaried employees of the Seller and its
         subsidiaries and their beneficiaries.  None of the Company, the Buyer
         or Niagara shall assume any liability with respect to the Quanex
         Corporation Deferred Compensation Plan.

                 (e)      Executive Incentive Compensation Plan.  Effective as
         of the Closing, the Seller shall cause the Company to terminate its
         participation as an adopting employer with respect to the Quanex
         Corporation Executive Incentive Compensation Plan maintained for the
         benefit of current and former key salaried employees of the Seller and
         its subsidiaries and their beneficiaries.  None of the Company, the
         Buyer or Niagara shall assume any liability with respect to the Quanex
         Corporation Executive Incentive Compensation Plan.

                 (f)      Management Incentive Program.  Effective as of the
         Closing, the Seller shall cause the Company to terminate its
         participation as an adopting employer with respect to the Quanex
         Corporation Management Incentive Program maintained for the benefit of
         current and former employees of the Seller and its subsidiaries and
         their beneficiaries.  Effective as of the Closing, the Seller shall
         cause that portion of the Quanex Corporation Management Incentive
         Program covering current and former salaried employees of the Company
         and their beneficiaries to be spun-off into a new deferred
         compensation plan entitled the "LaSalle Steel Company Management
         Incentive Program" which shall be solely a contractual obligation of
         the Company and which, as of the Closing, shall otherwise be
         substantially identical to the Quanex Corporation Management Incentive
         Program.

         employees of the Seller and its subsidiaries and their beneficiaries.
         Except as and to the extent reflected as a liability on the Closing

         current employees of the Seller and its subsidiaries.  None of the
         Company, the Buyer or Niagara shall assume any liability with respect
         to the Quanex Corporation Severance Allowance Policy.

         4.2  Further Assurances; Cooperation.

                 (a)      Each of the Parties shall from time to time after the
         Closing, upon the request of any other Party and without further
         consideration, execute, acknowledge and deliver in proper form such
         further instruments, and take such further actions, as such other
         Party may reasonably require, to carry out effectively the intent of
         this Agreement and the Other Documents.

                 (b)      The Seller shall, from time to time after the
         Closing, upon the request of Niagara, the Buyer or their designee, and
         without further consideration, execute, acknowledge and deliver in
         proper form such further instruments and take such further actions as
         Niagara or the Buyer may reasonably require, to record the Company or
         its designee as the record owner of any and all Intellectual Property
         owned by the Company which may currently be standing, as of record, in
         the name of the Company's predecessor in interest.

                 (c)      The Parties shall cooperate with each other in
         connection with any claim, action, suit, proceeding, inquiry or
         investigation by any other Person which relates to the execution and
         delivery of this Agreement or the Other Documents, or the consummation
         of the transactions contemplated hereunder and thereunder.

                 (d)      For a period of seven years following the Closing
         Date, each of the Parties will retain any records or files within its
         control after the Closing relating to the operations of the Company
         prior to the Closing (including those relating to the Taxes of the
         Company).  During such seven-year period, each Party shall afford any
         other Party, and such Party's counsel, accountants and other
         representatives, reasonable access to such records during normal
         business hours for any proper purpose.

         4.3     Notification of Certain Matters.   Niagara and the Buyer on
the one hand, and the Seller on the other hand, shall promptly notify the
other, in the manner provided in Section 7.9 hereof, of (i) any claim, action,
suit, proceeding, inquiry or investigation pending or, to such Party's
knowledge, threatened which relates to the execution and delivery of this
Agreement or the Other Documents, or the consummation of the transactions
contemplated hereunder or thereunder, (ii) any circumstance or development
which could adversely impair or affect its ability to perform its obligations
under this Agreement or the Other Documents, (iii) any notice or other
communication from any Person alleging that the consent of such Person is or
may be required in connection with the transactions contemplated by this
Agreement or the Other Documents or (iv) any notice or other communication from
any Governmental Authority in connection with the transactions contemplated by
this Agreement or the Other Documents.

         4.4     Confidentiality/Non-Competition.

                 (a)      The Seller acknowledges that Niagara and the Buyer
         would be irreparably damaged if Company Information (as defined below)
         were to be disclosed to or utilized on behalf of any Person, firm,
         corporation or other business organization that competes in any
         respect with the Business.  As used herein, "Company Information"
         shall include, without limitation, any and all proprietary or
         confidential information pertaining to the Company or its business or
         activities of any nature, including, without limitation, any
         information relating to (i) the Company's operation or management,
         finances or financial affairs, profits, profit





                                       23
<PAGE>   27
         margins, capital requirements, business methods, organization,
         procedures or Contracts, (ii) the Company's customers (including
         customer lists), suppliers or sources of supply, marketing strategies
         or data, products, product plans, service lines or pricing, (iii) the
         Company's personnel (including medical and salary information) and
         (iv) the Intellectual Property.  The Seller covenants and agrees that
         it will not, and will cause its agents, affiliates, advisors,
         directors, officers and employees (collectively, "Representatives")
         not to, at any time, without the prior written consent of Niagara, use
         or disclose any Company Information, except to employees and other
         authorized Representatives of Niagara or the Buyer; provided, however,
         that Company Information shall not include any information which (i)
         was or becomes generally available to or known by the public (other
         than as a result of a disclosure directly or indirectly by the Seller
         or its Representatives) or (ii) is available to the Seller on a
         non-confidential basis from a source other than Niagara, the Buyer or
         their Representatives; provided, further, however, that the Seller may
         use or disclose Company Information to the extent (i) required by Law
         and (ii) necessary in connection with its Tax filing obligations.  In
         the event that the Seller or any of its Representatives are legally
         compelled (by deposition, interrogatory, request for documents,
         subpoena, civil investigative demand or otherwise) to disclose any
         Company Information, such Person shall provide Niagara and the Buyer
         with prompt prior written notice of such demand so that Niagara or the
         Buyer may seek a protective order or other appropriate remedy or waive
         compliance with the provisions of this Section 4.4(a).  If a
         protective order or other remedy is not obtained and Niagara has not
         waived compliance with these provisions, the Seller or its
         Representatives, as the case may be, shall furnish only that portion
         of such Company Information which it is advised by its legal counsel
         is legally required to be disclosed.

                 (b)      The Seller agrees that for a period of two years
         following the Closing Date, it shall not directly or indirectly
         manufacture or invest in any entity which manufactures cold drawn or
         chrome-plated steel bars.

                 (c)      The Seller agrees that for a period of one year
         following the Closing Date, it shall neither solicit, persuade or
         induce any person employed by the Company to terminate his or her
         employment with the Company, nor, except for Persons whose employment
         has been terminated by the Company, employ any person employed by the
         Company as of the Closing Date or in the three-month period prior
         thereto without the consent of Niagara.

                 (d)      The Seller acknowledges and agrees that the
         provisions of this Section 4.4 are reasonable and necessary for the
         protection of Niagara, the Buyer and the Company.  It is understood
         and agreed that money damages would not be a sufficient remedy for any
         breach of this Section 4.4 by the Seller or its Representatives, and
         that Niagara and the Buyer shall be entitled to specific performance
         as a remedy for any such breach.  Such remedy shall not be deemed to
         be the exclusive remedy for any breach of this Section 4.4 but shall
         be in addition to all other remedies available pursuant to the terms
         of this Agreement.

         4.5     Expenses.  Except as otherwise specifically provided for
herein or in Paragraph 7 of the Letter of Intent (as defined in Section 7.3
hereof), each Party shall be solely responsible for all expenses incurred by it
or on its behalf in connection with the preparation and execution of this
Agreement and the Other Documents and the consummation of the transactions
contemplated hereby and thereby, including, without limitation, the fees and
expenses of its counsel, consultants, accountants, brokers, finders, investment
bankers, financial advisors and other representatives and advisors.

Section 338(h)(10) Election in accordance with any comparable provision of
applicable state or local Law, and the Parties responsible for filing any such
Section 338(h)(10) Election under applicable state or local Law shall promptly

taxing authority and provide written evidence of such filing to the other
Parties.  The Parties shall report the purchase by the Buyer of the Shares
consistent with the Section 338(h)(10) Election, and no Party shall take any

prepare and file all Tax Returns to be filed with any taxing authority in a
manner consistent with such allocation and shall take no position inconsistent
with such allocation in any Tax Return, any proceeding before any taxing
authority or otherwise, except in connection with the resolution of a Tax
Dispute in accordance with the provisions of Section 5.7 hereof.  In the event
that such allocation is disputed by any taxing authority, the Party receiving
notice of such dispute shall promptly notify and consult with the other Parties
concern- ing such dispute.

all Losses (as defined in Section 6.2 hereof) asserted against, resulting to,
imposed upon, or incurred by such Buyer Indemnified Party, directly or

         included the Company for all periods or portions thereof ending on or
         before the Closing Financial Statement Date, and (B) any state, local

         but not being limited to, the Tax Returns described in Section 5.6(a);

                 (ii)     any and all Taxes (other than Taxes described in

         Section 5.2(a)(i)) imposed upon the Company with respect to any
         taxable period beginning before and ending after the Closing Financial

<PAGE>   29
                 (vi)     any and all Taxes imposed upon the Company pursuant
         to Treasury Regulations Section 1.1502-6 (or any comparable provision
         under state, local, or foreign Tax Law imposing several liability upon

                 (vii)    any and all Taxes imposed upon the Company as a
         result of the Section 338(h)(10) Election.

         (b)     The indemnifications in favor of the Buyer Indemnified Parties
contained in subsections (ii), (iii), (iv) and (v) of Section 5.2(a) hereof
shall not be effective until the aggregate amount of all Losses in respect
thereof exceeds the Tax Accrual (as defined herein), and then only to the
extent such Losses exceed the Tax Accrual.  For purposes of this Agreement,
"Tax Accrual" shall mean and include the aggregate amount of accruals, reserves
and provisions for Taxes on the Closing Balance Sheet and the worksheets
thereto, it being understood that the Tax Accrual shall not include amounts on
the Closing Balance Sheet for "Deferred Income Taxes."

         (c)     Except as provided in Sections 5.2(a)(vi) and (vii) hereof,
nothing contained in this Section 5.2 shall require the Seller to indemnify any
Buyer Indemnified Party for any Losses with respect to any Taxes with respect
to any taxable period beginning after the Closing Financial Statement Date (a
"Post-Closing Period") or any portion beginning after the Closing Financial
Statement Date of any Straddle Period (a "Post-Closing" portion of such
Straddle Period).

         5.3     Tax Indemnity by Niagara and the Buyer.

         (a)     Without duplication, and subject to the provisions of this
Article V, Niagara and the Buyer shall, jointly and severally,  indemnify,
defend and hold harmless each Seller Indemnified Party (as defined in Section
6.3 hereof) from and against any and all Losses asserted against, resulting to,
imposed upon or incurred by such Seller Indemnified Party, directly or
indirectly, by reason of or resulting from:

                 (i)      to the extent provided in Section 5.3(b), any and all
         Taxes imposed upon the Company with respect to any Pre-Closing Period
         and for the Pre-Closing portion of any Straddle Period other than
         Taxes de- scribed in Sections 5.2(a)(i), (vi) and (vii) hereof;

                 (ii)     any and all Taxes imposed upon the Company with
         respect to any Post-Closing Period and the Post-Closing portion of any
         Straddle Period, other than Taxes described in Sections 5.2(a)(vi) and
         (vii) hereof;

                 (iii)    the breach or nonperformance of any covenant or
         agreement of Niagara or the Buyer contained in or made pursuant to
         this Article V.

         (b)     The indemnifications in favor of the Seller Indemnified
Parties contained in subsection (i) of Section 5.3(a) hereof shall not exceed,
in the aggregate, the amount of the Tax Accrual.

         5.4     Transfer Taxes.  Notwithstanding anything contained in this
Agreement to the contrary, any and all sales, use, transfer, stamp,
documentary, gains and other similar Taxes, and any transfer, recording or
similar fees and charges, imposed in connection with the consummation of the
transactions contemplated by this Agreement (collectively, "Transfer Taxes")
shall be borne one-half by the Buyer and one-half by the Seller.  The Parties
agree to use their commercially reasonable efforts to minimize the Transfer
Taxes.  Each of the Buyer and the Seller shall cause to be prepared and timely
filed all Tax Returns relating to Transfer Taxes ("Transfer Tax Returns") which
such Party has primary responsibility for filing under applicable Law and shall
cause all such Transfer Taxes to be duly and timely paid in full.  The Party
that has prepared any such Transfer Tax Return shall cause each such Transfer
Tax Return, together with all relevant work papers and other information, to be
delivered to the other Parties for their review and approval no later than 30
days prior to the due date for the filing of such Transfer Tax Return (giving
effect to any and all extensions thereof).  As between the Buyer and the
Seller, the Party not required to file such Transfer Tax Return under this
Section 5.4 shall pay to the other such Party's share of the Transfer Taxes due
and payable not later than seven days prior to the due date for payment of such
Transfer Taxes (giving effect to any and all extensions thereof).

         5.5     Allocation of Certain Taxes.  In the case of any Tax that
relates to any Straddle Period, the portion of such Tax attributable to the
Pre-Closing and Post-Closing portions of such Straddle Period shall be
determined as follows (provided, however, that this Section 5.5 shall not apply
with respect to any and all Taxes described in Sections 5.2(a)(vi) or (vii)
hereof):

         (a)     In the case of any franchise Tax based on capital and any ad
valorem Tax, the portion attributable to the Pre-Closing portion of such
Straddle Period shall be the amount of such Tax for the entire taxable period
multiplied by a fraction the numerator of which is the number of days
(including the Closing Financial Statement Date) in the Pre- Closing portion of
such Straddle Period and the denominator of which is the number of days in the
entire taxable period.  The amount of such Tax remaining after subtracting the
portion attributable to the Pre-Closing portion of such Straddle Period (as
determined in accordance with the preceding sentence) shall be the amount of
such Tax attributable to the Post-Closing portion of such Straddle Period.

         (b)     In the case of any such Tax not described in Section 5.5(a)
above, the portion attributable to the Pre- Closing portion of such Straddle
Period shall be determined on the basis of an interim closing of the books as
of and including the Closing Financial Statement Date, provided, however, that
for purposes of this Section 5.5(b), no amount attributable to the Section
338(h)(10) Election shall be taken into account.

         5.6     Return Filings, Refunds and Credits.

         (a)     The Seller shall (i) cause the Company to be included in the
consolidated federal income Tax Returns of the affiliated group (within the
meaning of Section 1504 of the Code) of which the Seller is the common parent
(within the meaning of Section 1504 of the Code) and the Indiana Corporation
Income Tax Returns (filed on a combined basis) that include the Seller and the
Company for (A) the taxable year of the Seller ended October 31, 1996 and (B)
the taxable year of the Seller that will end on October 31, 1997 (the "1997
Consolidated Returns"), which 1997 Consolidated Returns will include the tax
items of the Company for the portion of such taxable year ending on the Closing
Financial Statement Date, (ii) timely file such Tax Returns and (iii) timely
pay any Taxes shown as due on such Tax Returns.

         (b)     With respect to each Tax Return (other than the Tax Returns
described in Section 5.6(a) hereof) of the Company for Pre-Closing Periods
which have not been filed on or before the Closing Date,

                 (i)      the Seller shall prepare or cause to be prepared each
         such income Tax Return and franchise Tax Return; and

                 (ii)     the Buyer shall prepare or cause the Company to
         prepare all Tax Returns not described in Section 5.6(b)(i) hereof (to
         the extent not prepared before the Closing Date).

Subject to Sections 5.2, 5.3, 5.6(d) and 5.6(e) hereof, the Buyer shall timely
file or cause the Company to timely file the Tax Returns described in this
Section 5.6(b) and shall timely pay or cause to be timely paid all Taxes shown
as due thereon.  Subject to Sections 5.6(d) and 5.6(e) hereof, seven days prior
to the due date for the filing of each Tax Return referred to in this Section
5.6(b), the Seller shall pay to the Company the excess, if any, of (i) the
aggregate amount which will have been paid (when the amount of Taxes shown as
due on such Tax Return has been paid) by Niagara, the Buyer or the Company (to
any Seller Indemnified Party or to any taxing authority, as applicable)
pursuant to Section 5.3(a)(i) (including, but not limited to, payments made
under this Section 5.6) over (ii) the sum of (x) the Tax Accrual and (y) the
total aggregate amount previously paid to any Buyer Indemnified Party pursuant
to this Section 5.6.

         (c)     Subject to Sections 5.2, 5.3 and 5.6(d) and 5.6(e) hereof, the
Buyer shall prepare or cause to be prepared each Tax Return (other than the Tax
Returns described in Section 5.6(a) hereof) with respect to the Company for
Straddle Periods, shall timely file or cause the Company to timely file all
such Tax Returns, and shall timely pay or cause to be timely paid all Taxes
shown as due thereon.  Subject to Section 5.6(d) and 5.6(e) hereof, seven days
prior to the due date for the filing of each Tax Return referred to in this
Section 5.6(c),  the Seller shall pay to the Company the excess, if any, of (i)
the aggregate amount which will have been paid (when the amount of Taxes shown
as due on such Tax Return has been paid) by the Buyer or the Company (to a
Seller Indemnified Party or to any taxing authority, as applicable) pursuant to
Section 5.3(a)(i) (including, but not limited to, payments made under this
Section 5.6) over (ii)





                                       27
<PAGE>   31
the sum of (x) the Tax Accrual and (y) the total aggregate amount previously
paid to any Buyer Indemnified Party pursuant to this Section 5.6.

         (d)     The Tax Returns referred to in Sections 5.6(b) and 5.6(c)
hereof shall be prepared in a manner consistent with past practice (including,
without limitation, as to accounting methods and methods of measuring sales,
income, property values or other relevant items), unless a contrary treatment
is required by an intervening change in applicable Law.  The Seller shall cause
any Tax Return that is described in Section 5.6(b)(i) hereof, together with all
relevant work papers and any other information, to be delivered to Niagara and
the Buyer (in accordance with the provisions of Section 7.9 hereof) for their
review and approval at least 30 calendar days prior to the due date (giving
effect to any and all extensions thereof) for filing such Tax Return.  The
Buyer shall cause any Tax Return that is described in Section 5.6(b)(ii) or
5.6(c) hereof, together with all relevant work papers and other information, to
be delivered to the Seller (in accordance with the provisions of Section 7.9
hereof) for its review and approval at least 30 calendar days prior to the due
date (giving effect to any and all extensions thereof) for filing such Tax
Return.  With respect to any Tax Return described in Section 5.6(c) hereof
which is delivered to the Seller pursuant to the previous sentence, the Buyer
shall simultaneously deliver to the Seller (in accordance with the provisions
of Section 7.9 hereof) a statement (the "Buyer's Tax Statement") calculating
the portion of the Taxes shown as due on such Tax Return that is attributable
to the Pre-Closing portion of the Straddle Period under Section 5.5 hereof.
The costs and expenses incurred in connection with the preparation and delivery
of the Tax Returns referred to in Section 5.6(a) and (b)(i) hereof shall be
borne by the Seller.  The costs and expenses incurred in connection with the
preparation and delivery of the Tax Returns referred to in Section 5.6(b)(ii)
and (c) hereof and the Buyer's Tax Statement shall be borne by the Buyer.

         (e)     The amount of Taxes shown to be due on any Tax Return
described in Section 5.6(b) or 5.6(c) hereof and on any Buyer's Tax Statement
related thereto described in Section 5.6(d) hereof shall be final and binding
upon the Parties, unless whichever of the Parties did not prepare or cause the
preparation of such Tax Return or the Buyer's Tax Statement, as the case may be
(the "Other Party"), shall have delivered to the Party that prepared or caused
the preparation of such Tax Return (within 10 calendar days after the date of
the Other Party's receipt of such Tax Return and, if applicable, the Buyer's
Tax Statement related thereto) a written report containing all changes that the
Other Party proposes to make to such Tax Return and, if applicable, to the
Buyer's Tax Statement related thereto, which report shall set forth in
reasonable detail the basis for such changes.  The Parties shall undertake to
resolve any issues raised in any such report described in the first sentence of
this paragraph prior to the due date (including any extension thereof) for
filing such Tax Return and to mutually consent to the filing of such Tax Return
and, if applicable, to agree on the determination to be set forth in the
Buyer's Tax Statement related thereto, in which case the information and total
amount of Taxes shown to be due on such agreed Tax Return or, if applicable,
shown on such Buyer's Tax Statement (as agreed to) shall be final and binding
on the Parties.  In the event the Parties are unable to resolve any dispute by
the date that is 15 calendar days prior to the due date for filing of the Tax
Return in question (including any extension thereof), the Parties shall jointly
engage the Independent Accounting Firm to make its independent determination
with respect to the item or items in dispute and the amount or amounts related
thereto.  The Buyer and the Seller shall each bear and pay one-half of the fees
and other costs charged by the Independent Accounting Firm to perform such
function.  If the Independent Accounting Firm is so engaged, the Parties agree
to provide the Independent Accounting Firm with all books, records and other
information relevant to the determination of the disputed items and the
Independent Accounting Firm shall be instructed to make its determination as
soon as possible.  The Independent Accounting Firm's determination with respect
to the Tax treatment of any disputed item shall be made on the basis of the Tax
treatment for which the Independent Accounting Firm determines there is
substantial authority (or, if there is substantial authority for two or more
Tax treatments of such disputed item, the Tax treatment for which the weight of
the authorities supporting such Tax treatment is most substantial in relation
to the weight of authorities supporting the other Tax treatment or treatments).
The determination of the Independent Accounting Firm shall be final and binding
on the Parties enforceable by appropriate judicial proceedings.  In any case
where a disputed item has not been resolved (either by mutual agreement of the
Parties or by a determination of the Independent Accounting Firm) 10 calendar
days prior to the due date (including any extension thereof) for filing such
Tax Return, then the Party required to file such Tax Return under Section
5.6(b) or 5.6(c) hereof, as the case may be, shall cause such Tax Return to be
filed on the due date (including any extension thereof) for filing such Tax
Return without the Parties' mutual agreement or the Independent Accounting
Firm's determination with respect thereto and (i) the Independent Accounting
Firm shall make a determination with respect to any such disputed item and (ii)
the amount of Taxes determined to be due with respect to such Tax Return or, if
applicable, determined to be properly set forth on the Buyer's Tax Statement
related to such Tax Return, shall be the amount of Taxes that would have been
due on such Tax Return or, if applicable, be the amount of Taxes that would be
properly set forth on the Buyer's Tax





                                       28
<PAGE>   32
Statement related to such Tax Return, after giving effect to the Independent
Accounting Firm's determination.  Any overpayments or underpayments as between
the Parties shall be equitably adjusted to take into account the determination
of the Independent Accounting Firm, with interest on any such payments to be
paid, from the date of payment, at the rate charged by the IRS for
underpayments under Section 6621 of the Code.

         (f)     Any refunds or credits of Taxes of the Company for any
Pre-Closing Period or any Pre-Closing portion of any Straddle Period together
with any after-tax interest received or credited thereon shall be for the
account of the Seller and shall be paid by Niagara, the Buyer or the Company to
the Seller within 10 days after such Person receives or utilizes such refund or
credit (or interest thereon).  Any refunds or credits of Taxes of the Company
for any Post- Closing Period or any Post-Closing portion of any Straddle Period
together with any after-tax interest received or credited thereon shall be for
the account of the Buyer and shall be paid by the Seller to the Buyer within
ten days after the Seller receives or utilizes such refund or credit (or
interest thereon).  In applying the provisions of the first two sentences of
this Section 5.6(f), any refunds or credits of Taxes of the Company for any
Straddle Period together with any after-tax interest received or credited
thereon shall be allocated between the Seller and the Buyer in a manner
consistent with Section 5.5 hereof.

         5.7     Tax Contests.

         (a)     If any taxing authority proposes any adjustment or questions
the treatment of any item, which adjustment or question could, if pursued
successfully, result in or give rise to solely a claim for indemnification
against the Seller by any Buyer Indemnified Party under Section 5.2 hereof (a
"Seller Tax Claim"), solely a claim for indemnification against Niagara or the
Buyer by any Seller Indemnified Party under Section 5.3 hereof (a "Buyer Tax
Claim"), or both a Seller Tax Claim and a Buyer Tax Claim (a "Joint Tax
Claim"), then the Party first receiving notice of such adjustment or question
(a "Tax Dispute") shall promptly notify the other Parties in writing of such
Tax Dispute.

         (b)     In the case of a Buyer Tax Claim, the Buyer shall have the
right, at its sole cost and expense, to control the defense, prosecution,
settlement or compromise of the Tax Dispute underlying such Buyer Tax Claim.

         (c)     In the case of a Seller Tax Claim, the Seller shall have the
right, at its sole cost and expense, to control the defense, prosecution,
settlement or compromise of the Tax Dispute underlying such Seller Tax Claim.

         (d)     In the case of a Joint Tax Claim, the Buyer Indemnified Party
and the Seller Indemnified Party shall first attempt to separate such Joint Tax
Claim into two, one involving the Buyer Tax Claim portion thereof (which shall
be subject to the provisions of Section 5.7(b) hereof) and the other involving
the Seller Tax Claim portion thereof (which shall be subject to the provisions
of Section 5.7(c) hereof).  If the Buyer Indemnified Party and the Seller
Indemnified Party are not successful in accomplishing such separation, the
Buyer Indemnified Party and the Seller Indemnified Party shall, and shall cause
their respective affiliates to, consult and cooperate with each other in
controlling such audit, examination, investigation, or administrative, court,
or other proceeding, shall not compromise or settle such Joint Tax Claim
without the other's prior written consent (which consent shall not be
unreasonably withheld or delayed), and shall share the costs and expenses
associated with such Joint Tax Claim on such equitable basis as the Parties
shall mutually agree.  If the Buyer Indemnified Party and the Seller
Indemnified Party cannot agree with respect to any matter involving any such
Joint Tax Claim, the Buyer Indemnified Party and the Seller Indemnified Party
shall jointly engage independent tax counsel that is mutually acceptable to the
Buyer Indemnified Party and the Seller Indemnified Party to make its decision
with respect to such matter, which decision shall be final and binding on the
Parties, the Buyer Indemnified Party and the Seller Indemnified Party.  The
Buyer and the Seller shall each bear and pay one-half of the fees and other
costs charged by such counsel.

         (e)     The Party that controls a Tax Dispute under the provisions of
this Section 5.7 shall keep the other Parties informed of all significant
events and developments relating to such Tax Dispute and the other Parties, or
their authorized representatives, shall be entitled, at their own expense, to
attend (but not control) all conferences, meetings and proceedings with the
relevant taxing authority relating to such Tax Dispute.

         5.8     Cooperation.  The Parties shall, and Niagara and the Buyer
shall cause the Company to, cooperate, and shall cause their respective
directors, officers, employees, agents, accountants and representatives to
cooperate, in preparing and filing all Tax Returns (including amended Tax
Returns and claims for refund), in handling audits,





                                       29
<PAGE>   33
examinations, investigations, and administrative, court or other proceedings
relating to Taxes covered by this Agreement, in resolving all disputes, audits
and refund claims with respect to such Tax Returns and Taxes, and any earlier
Tax Returns and Taxes of the Company, and in all other Tax matters to which
this Agreement relates, in each case including making employees available to
assist the requesting Party, timely providing information reasonably requested,
maintaining and making available to each other all records necessary in
connection therewith, and the execution and delivery of IRS Form 2848 (or a
successor form or forms) and comparable forms for foreign, state and local Tax
purposes, as appropriate, when the requesting party reasonably requires such
forms in connection with any Tax Dispute and claims for refund.  Any
information obtained by a Party or its affiliates from another Party or its
affiliates in connection with any Tax matters to which this Agreement relates
shall be kept confidential, except (i) as may be otherwise necessary in
connection with the filing of Tax Returns or claims for refund or in conducting
an audit or other proceeding relating to Taxes or as may be otherwise
reasonably required by applicable Law, (ii) for any external disclosure in
audited financial statements or regulatory filings which a Party reasonably
believes is required by applicable law or stock exchange rules or (iii) for any
disclosure which a Party or its affiliates, as the case may be, reasonably
believes is required by an entity which has made financing available to such
Party or affiliate or to which such Party or affiliate has applied for
financing in connection with this Agreement or with any other agreement (a
"Lender"), provided that such Lender shall have agreed to keep all such
information confidential.

         5.9     Termination of Tax Sharing Agreements.  Except as provided in
this Agreement, any and all Tax allocation agreements, Tax sharing agreements,
intercompany agreements, intercompany Indebtedness, or other agreements or
arrangements between the Company and the Seller or any of the Seller's
Affiliates and relating to any Tax matters shall be terminated with respect to
the Company as of the Closing Financial Statement Date, and from and after such
time will have no further force or effect for any taxable period (whether past,
current, or future taxable periods).

         5.10    Purchase Price.  Unless otherwise required by applicable Law,
the Parties shall treat any payments of Taxes made pursuant to this Article V
as an adjustment to the Purchase Price for federal, state and local Tax
purposes.

         5.11    Payments.  Except as otherwise provided in this Article V, any
amount to which a Party is entitled under this Article V shall be promptly paid
in immediately available funds to such Party by the Party or Parties obligated
to make such payment within five business days after written notice to the
Party so obligated stating that the Taxes to which such amount relates are due
or have been paid and providing details supporting the calculation of such
amount, but in no event shall such payment be required to be made earlier than
seven calendar days before the due date (giving effect to any and all valid
extensions) for payment of such Taxes.

         5.12    Survival.  All representations and warranties contained in
Section 2.18 hereof, and all covenants and agreements contained in or made
pursuant to this Article V, shall survive until 90 calendar days following
expiration of the applicable statute of limitations (including any and all
valid extensions thereof), provided, however, that a claim for indemnification
made within the applicable survival period in respect of any such
representation, warranty, covenant or agreement may continue to be asserted
beyond such period.

         5.13    Exclusivity of Article V.  Notwithstanding anything in this
Agreement to the contrary, this Article V shall be the exclusive agreement
among the Parties with respect to indemnification for any Losses in respect of
Taxes.


                                   ARTICLE VI

                        SURVIVAL OF REPRESENTATIONS AND
                          WARRANTIES; INDEMNIFICATION

         6.1     Survival of Representations and Warranties.  All
representations and warranties of the Parties contained herein shall survive
the Closing and any investigation at any time made by or on behalf of any Party
for a period of two years after the Closing Date; provided, however, that the
representations and warranties contained in Section 2.18 (Taxes)  hereof shall
survive in accordance with the provisions of Section 5.12 hereof.  Provided
that a claim with respect to a breach of representation or warranty is made
within the applicable period, it may continue to be asserted beyond such period
with respect to the representation or warranty to which such claim relates.

         6.2     Indemnification by the Seller.  Subject to the provisions of
this Article VI, and in addition to the obligations of the Seller pursuant to
Section 5.2 hereof, the Seller shall indemnify, defend and hold harmless
Niagara, the Buyer, any parent, subsidiary or affiliate of, and any director,
officer, employee, agent or advisor of, any of them, or any of their respective
heirs, successors or assigns (a "Buyer Indemnified Party"), from and against
any and all demands, claims, actions, causes of action, assessments, losses,
damages, liabilities, judgments, settlements, fines, penalties, sanctions,
costs, deficiencies and expenses (including, without limitation, reasonable
attorneys' fees and disbursements, interest and penalties, and all other
reasonable costs of investigating and defending third party claims as incurred)
(collectively, "Losses") asserted against, resulting to, imposed upon or
incurred by any Buyer Indemnified Party, directly or indirectly, by reason of
or resulting from:

                          (i)     the breach of or any inaccuracy in any of the
                 representations and warranties of the Seller contained in or
                 made pursuant to this Agreement;

                          (ii)    the breach or nonperformance of any covenant
                 or agreement of the Seller contained in or made pursuant to
                 this Agreement; and

                          (iii)   any guarantee by the Company, made  prior to
                 the Closing, of Indebtedness of the Seller or any Seller's
                 Affiliate.

         6.3     Indemnification by Niagara and the Buyer.  Subject to the
provisions of this Article VI, and in addition to the obligations of Niagara
and the Buyer under Section 5.3 hereof, Niagara and the Buyer shall, jointly
and severally, indemnify, defend and hold harmless the Seller, any parent,
subsidiary or affiliate of the Seller, and any director, officer, employee,
agent or advisor of any of them or any of their respective heirs, successors or
assigns (a "Seller Indemnified Party"), from and against any and all Losses
asserted against, resulting to, imposed upon or incurred by any Seller
Indemnified Party, directly or indirectly, by reason of or resulting from:

                          (i)     the breach of or any inaccuracy in any of the
                 representations and warranties of Niagara or the Buyer
                 contained in or, made pursuant to this Agreement;

                          (ii)    the breach or non-performance of any covenant
                 or agreement of Niagara or the Buyer contained in or made
                 pursuant to this Agreement; and

                          (iii)   any actions or omissions by a Buyer
                 Indemnified Party or the Company following the Closing with
                 respect to any Designated Plan that is sponsored by the
                 Company immediately prior to the Closing; and

                          (iv)    any matter relating to the Buyer Salaried
                 Pension Plan (as defined in Section 4.1(a) hereof), the

         6.5     Indemnification Procedures.

                 (a)      Notice.  If any legal proceeding shall be threatened
         or instituted or any claim or demand shall be asserted by any Buyer
         Indemnified Party or Seller Indemnified Party in respect of which
         indemnification may be sought under the provisions of this Agreement,
         the Party seeking indemnification (the "Claiming Party") shall
         promptly cause written notice of the assertion of any such claim,
         demand or proceeding of which it has knowledge to be forwarded to the
         Party from whom it is claiming indemnification (the "Indemnitor").
         Such notice shall contain a reference to the provisions hereof or of
         such other agreement, instrument or certificate delivered pursuant
         hereto, in respect of which such claim is being made, and shall
         specify, in reasonable detail, the amount of such Loss if determinable
         at such time.  The Claiming Party's failure to give the Indemnitor
         prompt notice shall not preclude the Claiming Party from seeking
         indemnification from the Indemnitor unless the Claiming Party's
         failure has materially prejudiced the Indemnitor's ability to defend
         the claim, demand or proceeding.

                 (b)      Third Party Claims.  If the Claiming Party seeks
         indemnification from the Indemnitor as a result of a claim or demand
         being made by a third party (a "Third Party Claim"), the Indemnitor
         shall have the right to promptly assume the control of the defense of
         such Third Party Claim, including, at its own expense, employment by
         it of counsel reasonably satisfactory to the Claiming Party. The
         Claiming Party may, in its sole discretion and at its own expense,
         employ counsel to represent it in the defense of the Third Party
         Claim, and in such event counsel for the Indemnitor shall cooperate
         with counsel for the Claiming Party in such defense, provided that the
         Indemnitor shall direct and control the defense of such Third Party
         Claim or proceeding.  The Indemnitor shall not consent to the entry of
         any judgment, except with the written consent of the Claiming Party,
         and shall not enter into any settlement of such Third Party Claim
         without the written consent of the Claiming Party which (i) does not
         include as an unconditional term thereof the release of the Claiming
         Party from all liability in respect of such Third Party Claim or (ii)
         results in the imposition on the Claiming Party of any remedy other
         than money damages.  If the Indemnitor elects not to exercise its
         rights to assume the defense of the Third Party Claim, or if
         injunctive relief is sought which would have an adverse effect on the
         Claiming Party (or the Company if a Buyer Indemnified Party is the
         Claiming Party), the Claiming Party may, but shall have no obligation
         to, defend against such Third Party Claim or legal proceeding in such
         manner as it may deem appropriate, and the Claiming Party may
         compromise or settle such Third Party Claim and proceeding without the
         Indemnitor's consent.

                 (c)      Payment.  After any final judgment or award shall
         have been rendered by a court, arbitration board or administrative
         agency of competent jurisdiction and the time in which to appeal
         therefrom shall have expired, or a settlement shall have been
         consummated, or the Claiming Party and the Indemnitor shall arrive at
         a mutually binding agreement with respect to each separate matter
         alleged to be indemnified by the Indemnitor hereunder, the Claiming
         Party shall forward to the Indemnitor notice of any sums due and owing
         by it with respect to such matter (in accordance with Section 7.9
         hereof) and the Indemnitor shall pay all of the sums so owing to the
         Claiming Party by wire transfer, certified or bank cashier's check
         within 10 days after the date of such notice.

         6.6     Application to Taxes.  Notwithstanding anything in this
Agreement to the contrary, Article V shall be the exclusive agreement among the
Parties with respect to indemnification for any Losses in respect of Taxes.

         6.7     Remedies.  Except for Losses resulting from fraud, the rights
and remedies specifically provided for in this Agreement shall be the exclusive
rights and remedies of the Parties.  Without limiting the foregoing, each of
Niagara and the Buyer waives any rights and remedies it may have against the
Seller under any Environmental Law, including without limitation the
Comprehensive Environmental Response, Compensation and Liability Act, the
Indiana Responsible Property Transfer Law and the Indiana Hazardous Substances
Response Trust Fund Law.  For purposes of this Agreement, any statement made by
the Company in a notice delivered or filed pursuant to the Indiana Responsible
Property Transfer Law in connection with the financing arrangements of the
Buyer and its affiliates shall not be deemed to be a representation, warranty,
agreement or covenant pursuant to this Agreement and the Parties acknowledge
that the Seller shall not have any responsibility concerning the preparation,
delivery or filing of such notice.

assigned by any of the Parties without the prior written consent of the other
Parties.

                 (b)      This Agreement is not intended, nor shall it be
         construed, to confer upon any Person, except the Parties and their
         respective successors and permitted assigns, any rights or remedies
         under or by reason of this Agreement.

         7.2     Exhibits and Disclosure Schedule.  All Exhibits annexed hereto

instruments referred to herein, together with the letter agreement dated the
date hereof by and among the Parties, embody the entire agreement and
understanding of the Parties in respect of the transactions contemplated by

         7.4     Waiver of Compliance.  No amendment, modification, alteration,
supplement or waiver of compliance with any obligation, covenant, agreement or
provision hereof or consent pursuant to this Agreement shall be effective
unless evidenced by an instrument in writing executed by both of the Parties or
in the case of a waiver, the Party against whom enforcement of any waiver, is
sought.  Any waiver or failure to insist upon strict compliance with such
obligation, covenant, agreement, or provision shall not operate as a waiver of,
or estoppel with respect to, any subsequent or other failure.

         7.5     Validity.  The invalidity or unenforceability of any provision
of this Agreement shall not affect the validity or enforceability of any other
provisions of this Agreement, each of which shall remain in full force and
effect.

         7.6     Counterparts.  This Agreement may be executed in counterparts,
each of which shall be deemed an original but all of which together shall
constitute one and the same instrument.
