ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

On November 5, 1997, Centrum Industries, Inc. (Centrum) acquired substantially
all of the assets of Northern Steel, Inc. (NSI), a privately held Seattle based
supplier of material handling equipment, through a subsidiary which will do
business as Northern Steel Company (Northern).

Centrum is a holding company with three manufacturing segments:  Metal Forming
Operations, Material Handling Systems, and Motor Production Systems.  Northern
will become part of Centrum's material handling systems segment.  Northern will
supply shelving, racks, conveyors and other storage and distribution equipment
as components of material handling systems.  Centrum's current subsidiary,
American Handling based in Ohio, primarily provides material handling systems
engineering and equipment integration.  The addition of Northern to the segment
will expand the depth of the markets addressed and provide a national presence.

The assets acquired were substantially all of the assets of NSI.  Those assets
principally consisted of accounts receivable, inventory and other assets
reduced by accounts payable and other liabilities.  The purchase price was
determined through negotiations between Centrum management and the management
of NSI and its parent corporation, based upon the fair value of NSI's assets,
customer base, and recent operating results.  This transaction will be 
accounted for under the purchase method of accounting. The total purchase 
price of approximately $2.8 million was financed by a draw of $1.5 million on 
a newly instituted line of credit with Huntington National Bank (Bank) at the 
material handling systems segment and $1.3 million in cash.  The terms of the 
line of credit are similar to the terms of the existing line of credit with 
the Bank at the metal forming operations.  Please see the 10-K filed for the 
fiscal year ended March 31, 1997 for a detailed discussion of those terms.

purchased by Buyer hereunder; and

by wire transfer at Closing in accordance with the Escrow Agreement in the form

Retained Liabilities (as defined in Section 2.8) and indemnification

                 (b)      The Purchase Price for all of the Assets shall be
allocated at Closing, exclusive of Centrum Subsidiary's acquisition costs, to
the Assets in accordance with Section 1060 of the Internal Revenue Code, as
amended, and as set forth in EXHIBIT D attached hereto and incorporated herein.
The parties agree that the Purchase Price allocations shall be based upon and
reflect the net fair market values of the Assets being purchased hereunder as
determined by the parties exclusive of Centrum Subsidiary's acquisition costs.
Neither Centrum Subsidiary nor the Company will do anything, or fail to take
any action, which by reason of such doing or such failure, would be considered
as inconsistent with any of the allocations set forth on EXHIBIT D for federal
or state income tax purposes or any other purpose.

                 2.5      PURCHASE PRICE ADJUSTMENT.

                 (a)      The Purchase Price shall be subject to adjustment
based upon the audited financial statements to be prepared as of Closing Date
(the "Closing Date Financial Statements").  The fees and costs of the Auditor
will be borne by the Company.  The Net Worth of the Company as of the Closing
Date (the "Closing Net Worth") shall be calculated by the Auditors in
accordance with GAAP applied on a consistent basis and reflecting changes from
operations from December 31, 1996 to the Closing Date and shall be delivered to
each of the Parties and to the Escrow Agent within forty-five (45) days of the
Closing Date (the "Net Worth Notification").  The Company and Centrum
Subsidiary shall cooperate with the Auditors to determine the Closing Net
Worth.  In that connection, Centrum Subsidiary shall permit Keller to assist in
preparation of the Closing Date Financial Statements and shall provide access
to the Company and the Auditors to all relevant records in Centrum Subsidiary's
possession.  The Auditors shall provide to the Buyer's independent certified
public accountants full access to its workpapers and reports related thereto,
any and all records and documentation necessary to perform an audit, including
any and all records and documentation in the possession of the Auditors.  In
the event Buyer and its independent certified public accountants agree with the
Auditor's determination of the

<PAGE>   16

Closing Net Worth or do not agree with the Auditors' determination of the
Closing Net Worth but the amount of the dispute is less than Ten Thousand
Dollars ($10,000.00) in the aggregate, the determination of the Auditors shall
prevail and the Company and the Buyer shall notify the Escrow Agent of the
Auditor's determination within fifteen (15) days of their receipt of the Net
Worth Notification.  In the event that the Buyer disputes the Closing Net Worth
as determined by the Auditors, and such dispute involves an aggregate of Ten
Thousand Dollars ($10,000.00) or more, the Buyer shall notify the Company and
Escrow Agent within fifteen (15) days of its receipt of the Net Worth
Notification.  If such dispute is not resolved by the Company and Centrum
Subsidiary and notified to Escrow Agent within ten (10) days of notification
thereof, it shall be submitted to the Disputes Auditor.  The decision of the
Disputes Auditor shall be final and shall be notified to the Parties and Escrow
Agent within thirty (30) days of submission.  The fees and expenses of the
Disputes Auditor shall be borne by the Company and Centrum Subsidiary equally.
Upon final determination of the Closing Net Worth, the Auditor (or the Disputes
Auditor, as the case may be) shall make the certification to the Escrow Agent
in the form of EXHIBIT A to the Escrow Agreement.

                 (b)      The Purchase Price shall be reduced dollar for dollar
for each dollar by which the Closing Net Worth is less than One Million Six
Hundred One Thousand Dollars ($1,601,000.00) (the "August 31, 1997 Net Worth").
There will be no increase in the Purchase Price in the event the Net Worth of
the Company as of the Closing Date exceeds the August 31, 1997 Net Worth.

                 (c)      Except for any increases subsequent to August 31,
1997 in the U S Bank Debt that are a direct result of inventory purchased in
the Ordinary Course of Business or accounts receivable resulting from sales of
products or services in the Ordinary Course of Business, the amount of the U S
Bank Debt as of the Closing Date for purposes of determining the Purchase Price
shall not exceed One Million Three Hundred Thousand Dollars ($1,300,000.00).

                 (d)      The Purchase Price shall be increased dollar for
dollar up to a maximum of Two Hundred Thousand Dollars ($200,000.00) for each
dollar by which the amount of the U S Bank Debt as of the Closing Date is less
than One Million Ninety-Seven Thousand Dollars ($1,097,000.00).  Amounts
deposited in lockboxes with automatic sweeps to Company's U S Bank account as
of the Closing Date shall be regarded as reductions in the amount of the U S
Bank debt as of such date for purposes of this Section 2.5(d) so long as the
Buyer is paid such amounts as contemplated in Section 2.4(a)(ii) hereof.

                 (e)      The term "Adjusted Purchase Price" shall mean the
Purchase Price after all the adjustments applicable under this Section 2.5.

                 2.6      ESCROW.

fluctuation in value and reasonably acceptable to the Company and Buyer, and
shall hold and disburse the Escrow Amounts and any interest accrued thereon in
accordance with the terms of the Escrow Agreement.

                 (b)      Upon final determination of the Adjusted Purchase
Price pursuant to Section 2.5(a), the Auditor (or Disputes Auditor, as the case
may be) shall deliver to the Escrow Agent a certification in the form of
EXHIBIT A to the Escrow Agreement.  The Escrow Agent shall disburse to the
Buyer the amount, if any, by which the Adjusted Purchase Price is less than the
Purchase Price (the "Price Adjustment"), plus accrued interest thereon, up to a
maximum of the Escrow Amounts and interest accrued thereon.  The Company shall
promptly deposit in escrow with the Escrow Agent the amount of the Price
Adjustment, plus interest accrued thereon, it being understood by the parties
hereto that after payment of the Price Adjustment to Buyer, there will
initially remain in escrow as the Indemnification Allowance the sum of One
Hundred Seventy-Five Thousand Dollars ($175,000.00).

                 (c)      In the event that the Price Adjustment exceeds the

making the deposit in escrow referred to in (b) above, shall remit the
difference, plus accrued interest thereon, calculated at the same rate as
interest on funds in escrow, to the Buyer within thirty (30) days.

satisfactory to it that the Company has paid or evidence that funds are needed

including the Closing Date, Escrow Agent shall disburse to the Company from the
Indemnification Allowance the amount paid by the Company to such taxing
authority.
                 (e)      Upon receipt of written instructions from the Company
and Centrum Subsidiary, Escrow Agent shall disburse all of the remaining
Indemnification Allowance, including interest accrued thereon, to the Company.

                 (f)      Unless on or prior to November 1, 1998 Centrum
Subsidiary shall have given written notice to the Company and Escrow Agent of a
claim or claims by Centrum Subsidiary against the Company arising from a breach
of the Company of any of the provisions of this Agreement (a "Buyer Claim"),
Escrow Agent shall disburse all of the remaining Indemnification Allowance,
including interest accrued thereon, to the Company.

                 (g)      If Escrow Agent receives written notice from Centrum
Subsidiary of a Buyer Claim prior to November 1, 1998, Escrow Agent shall hold,
retain and not





                                       12


<PAGE>   18

disburse the amount of such Buyer Claim from the Indemnification Allowance
unless and until Escrow Agent receives written notice from the Company and
Centrum Subsidiary, or a final order of a court of competent jurisdiction,
directing Escrow Agent to disburse the Indemnification Allowance to the
Company, any taxing authority or any claimant whose Buyer Claim is based upon a
Retained Liability.  Escrow Agent shall, however, disburse to the Company the
amount by which the Indemnification Allowance exceeds the sum of all Buyer
Claims.

                 (h)      All costs and fees for the administration and
handling of the Escrow Amounts will be paid by Buyer.

any Tax for which no return was required, for any period for which a payment as
to such type of Tax has been made; or (C) any Tax for any period for which a
Tax Return is due but has not been filed.  There is no dispute or claim

action taken prior to or on the date hereof, a United States real property
holding corporation within the meaning of Code Sec. 897(c)(2) (or any

Company disclosed on its federal income Tax Returns all positions taken therein
that could give rise to a substantial understatement of federal income Tax
within the meaning of Code Sec. 6661 or Code Sec. 6662 or any penalty under the
Code (or any corresponding provisions of state, local or foreign income tax
Law).  The Company has at all times prior to and including the date hereof with

In the event that the Buyer is requested or required (by oral question or
request for information or documents in any legal proceeding, interrogatory,
subpoena, civil investigative demand, or similar process) to disclose any
Confidential Information, the Buyer will notify the Company, promptly of the
request or requirement so that the Company may seek an appropriate protective
order or the receipt of a waiver of compliance with the provisions of this
Section 6(b).  If, in the absence of a protective order or the receipt of a
waiver hereunder, the Buyer is, on the advice of counsel, compelled to disclose
the Confidential Information to the tribunal or else stand liable for contempt,
the Buyer may disclose the Confidential Information to the tribunal; provided,
however, that the Buyer shall use all its best efforts to obtain, at the
request of the Company, an order or other assurance that confidential treatment
will be accorded to such portion of the Confidential Information required to be
disclosed as the Company shall designate.  The foregoing provisions shall not
apply to any Confidential Information which is generally available to the
public immediately prior to the time of disclosure through no fault of Buyer.
As used in this Agreement, the term "Confidential Information" means all trade
secrets, proprietary information, confidential business information, and/or
confidential or proprietary Know-How of the Company disclosed to the Buyer
(including ideas, formulas, compositions, inventions (whether patentable or
unpatentable and whether or not reduced to practice), drawings, specifications,

with Company or Buyer; (iii) is independently developed by or for the Buyer by

the Company owned by it after the Closing Date, Duke shall become liable for all
of the Company's obligations under this Agreement, including without limitation,
all provisions of Article 8 hereof.

requesting Party (unless the requesting Party is entitled to indemnification
therefor under Section 8 below).  The Company acknowledges and agrees that from

documents, books, records, agreements, and financial data of any sort relating

event that the Company is requested or required (by oral question or request
for information or documents in any legal proceeding, interrogatory, subpoena,
civil investigative demand, or similar process) to disclose any Confidential
Information, the Company will notify the Buyer, promptly of the request or
requirement so that the Buyer may seek an appropriate protective order or the

entitled to indemnification therefor under Section 8 below).

                 (d)      TRANSITION.  The Company will not take any action

Company will refer all customer inquiries relating to the business of the
Company to the Buyer from and after the Closing.

under terms and conditions satisfactory to Centrum Subsidiary.  The Company
will assist Buyer in hiring any of such employees and for a period of three (3)
years will not directly or indirectly employ any of such employees in the
employ of Buyer without first having obtained Buyer's consent.  It is

or engage all or substantially all of the employees of the Company.  The
Company will pay all severance pay or benefits, vacation pay, sick pay, accrued
pension benefits, wages, commissions, and other compensation due to Company's
employees up to and including the Closing Date.  In view of the foregoing, the

accounts receivable to the Company so that the Company may pursue collection
efforts.  Thereafter, at no expense to the Company, Buyer shall make reasonable
efforts to assist the Company in the collection of such accounts and continue

that are deposited into Buyer's lockbox and promptly deliver such collections
to Company.

benefits under the Nonassignable Contract in exchange for Buyer undertaking all
of Company's obligations under the Nonassignable Contract.

sought (the "Indemnifying Party") prompt written notice of any claims with
respect to which the Indemnifying Party has agreed to indemnify the Indemnified
Party under Section 8(b) and Section 8(c).  Upon request, the Indemnified Party
shall give the Indemnifying Party access to such





                                       56


<PAGE>   62

information possessed by the Indemnified Party as the Indemnifying Party
reasonably requests relating to such claim.

                          (ii)    The Indemnified Party shall initially
undertake the defense of any third party claim (at the expense of the
Indemnifying Party) until the Indemnifying Party notifies the Indemnified Party
in writing that the Indemnifying Party is assuming the defense of such claim,
whether or not involving litigation; provided, however, that the Indemnifying
Party may assume such defense while reserving the right to contest the
Indemnified Party's entitlement to indemnification; and provided further that
the Indemnified Party may at any time, at its election, participate (including
through representation by attorneys of its own) in such defense; provided that
such participation shall be at the Indemnified Party's own expense unless the
named parties to such claim (including any impleaded parties) include both the
Indemnified Party and the Indemnifying Party and the Indemnified Party shall
have been advised by counsel that there are one or more legal defenses
available to it which are different from or additional to those available to
the Indemnifying Party, it being understood, however, that in such case the
Indemnifying Party shall not, in connection with any one such action or
separate but substantially similar or related actions in the same jurisdiction
arising out of the same general allegations or circumstances, be liable for the
reasonable fees and expenses of more than one separate firm of attorneys.  At
the Indemnifying Party's reasonable request, the Indemnified Party will
cooperate with the Indemnifying Party in the preparation of such defense if the
Indemnifying Party reimburses the Indemnified Party for the reasonable expenses
incurred in connection with such request.  The Indemnifying Party shall not
settle any such claim for consideration other than money without the prior
written consent of the Indemnified Party and the Indemnifying Party shall not,
without the prior written consent of the Indemnified Party, settle or
compromise any claim or consent to the entry of any judgment that does not
include as an unconditional term thereof the giving by the claimant or
plaintiff to the Indemnified Party of a release from all liability in respect
of such claim (or, if the claims by the claimant or plaintiff are broader than
the Indemnifying Party's indemnification obligation, in respect of such portion
of such claim to which the Indemnifying Party has an indemnification
obligations under this Section 8.)  The Indemnifying Party contesting or
defending a third party claim shall afford to the Indemnified Party and its
counsel an opportunity to be present (as long as no participant to such
conferences objects) in conferences with all persons, including governmental
authorities, asserting such claims and conferences with representatives or
counsel for such persons at such other party's sole cost and expense.

                          (iii)   If the Indemnifying Party does not assume the
defense of a third party claim in a timely manner, then the Indemnified Party
may do so upon reasonable notice to the Indemnifying Party.  Reasonable
attorneys' fees and court costs incurred by the Indemnified Party for such
defense shall, without duplication be included as Adverse Consequences for
which the Indemnifying Party is responsible to the extent otherwise provided in
this Agreement.

                          (iii)    Anything to the contrary contained in this

significance.  If any Party has breached any representation, warranty, or
covenant contained herein in any respect, the fact that there exists another
representation, warranty, or covenant relating to the same subject matter
(regardless of the relative levels of specificity) which the Party has not
breached shall not detract from or mitigate the fact that the Party is in
breach of the first representation, warranty, or covenant.

proceeding may be heard and determined in any such court, and agrees not to
bring any action or proceeding arising out of or relating to this Agreement in
any other court.  Each of the Parties waives any defense of inconvenient forum
to the maintenance of any action or proceedings so brought and waives any bond,
surety, or other security that might be required of any other Party with
respect thereto.  Any Party may make service on any other Party by sending or
delivering a copy of the process to the Party to be served at the address and

conclusive and may be enforced by suit on the judgment or in any other manner
provided by Law.
