                    ACQUISITION AGREEMENT AND PLAN OF MERGER


         THIS ACQUISITION AGREEMENT AND PLAN OF MERGER (this "Agreement") dated
October 23, 2000, is between Quanex Corporation, a Delaware corporation
("Parent"), Quanex Five, Inc., a Delaware corporation and wholly owned
subsidiary of Parent ("Sub"), and Temroc Metals, Inc., a Minnesota corporation
("Temroc").

         WHEREAS, Temroc is engaged in the business of manufacturing and selling
customized aluminum extrusions and fabricated metal products and operations
incidental thereto (the "Business");

         WHEREAS, Parent, Sub and Temroc wish to set forth the representations,
warranties, agreements and conditions under which the merger of Sub with and
into Temroc (the "Merger") will occur;

         NOW THEREFORE, in consideration of the mutual agreements and covenants
contained in this Agreement and for other good, fair and valuable consideration,
the receipt and sufficiency of which are acknowledged, Parent, Sub and Temroc
agree as follows:

         1. GENERAL DESCRIPTION OF THE MERGER.

                  1.1 EFFECTIVENESS OF THE MERGER. Subject to the terms and
conditions of this Agreement, Sub shall be merged with and into Temroc in
accordance with the General Corporation Law of the State of Delaware (the
"Delaware Law") and the Minnesota Business Corporation Act (the "Minnesota
Act"). Subject to the provisions of Articles 6 and 7 of this Agreement
(regarding conditions to the Merger), the closing of the Merger shall take place
in the manner and at the time described in Article 2 of this Agreement. The
Merger shall be effective at the time (the "Effective Time") when (i) a properly
executed certificate of merger (the "Certificate of Merger") in substantially
the form attached to this Agreement as Exhibit A (together with any other
documents required by the Delaware Law to effect the Merger) shall have been
filed with the Secretary of State of Delaware and (ii) properly executed
articles of merger (the "Articles of Merger") in substantially the form attached
to this Agreement as Exhibit B (together with any other documents required by
the Minnesota Act to effect the Merger) shall have been filed with the Secretary
of State of Minnesota.

                  1.2 NAME AND GOVERNING LAW OF THE SURVIVING CORPORATION.
Following the Merger, the separate corporate existence of Sub shall cease and
Temroc shall continue as the surviving corporation (the "Surviving Corporation")
under the name "Temroc Metals, Inc.", and shall be organized under and be
governed by the Minnesota Law. The Surviving Corporation shall possess all the
rights, privileges, powers and franchises and be subject to all the
restrictions, disabilities and duties of each of Temroc and Sub.

                  1.3 CHARTER DOCUMENTS OF THE SURVIVING CORPORATION. (a) At the
Effective Time of the Merger, the articles of incorporation of the Surviving
Corporation shall be the amended and restated articles of incorporation of
Temroc as provided in the Articles of Merger, and shall continue as the Amended
and Restated Articles of Incorporation of the Surviving Corporation until
further amended in the manner provided by the Minnesota Act.

   14

                  (b) At the Effective Time of the Merger, the bylaws of the
Surviving Corporation shall be the bylaws attached to this Agreement as Exhibit
C, until amended in the manner provided therein or by the provisions of the
Minnesota Act or the Amended and Restated Articles of Incorporation of the
Surviving Corporation.

                  1.4 OFFICERS AND DIRECTORS OF THE SURVIVING CORPORATION. (a)
The directors of Sub at the Effective Time of the Merger shall be the directors
of the Surviving Corporation and shall hold office until the earlier of their
resignation or removal or until their successors are duly elected and qualified.

                  (b) The officers of Sub at the Effective Time of the Merger
shall be the officers of the Surviving Corporation and shall hold office until
the earlier of their resignation or removal or until their successors are duly
elected and qualified.

                  1.5 DISPOSITION OF PARTNERSHIP INTERESTS AND AACRON CAPITAL
STOCK. Immediately prior to the Closing, Temroc will sell, distribute or
otherwise transfer all of its right, title and interest in and to the Medina
Parks, Highway 55 and 18 and JGM Energy Investments - Mon. Dak. - - 1981-3
Drilling Fund partnerships (the "Partnerships") and all of the capital stock of
Aacron, Inc. ("Aacron"), so that as a result of such sales, distributions or
transfers, Temroc shall not have any direct or indirect ownership interest in
the Partnerships or Aacron.. All of the agreements relating to those sales,
distributions and transfers shall be subject to written agreements, which shall
contain provisions releasing Temroc and its affiliates and successors from any
liabilities with respect to the interests and stock sold and the assets of the
Partnerships and Aacron and indemnifying them with respect to those liabilities.
The form and substance of the provisions releasing Temroc and its affiliates and
survivors from those liabilities and indemnifying them with respect to those
liabilities shall be in a form reasonably satisfactory to Parent.

                  1.6 CONVERSION OF STOCK. In reliance on the representations
and warranties of Temroc contained in this Agreement, and on the terms and
subject to the conditions set forth in this Agreement, except as provided in
Section 1.7 (regarding shares held by dissenting shareholders), Parent shall pay
the shareholders of Temroc a total consideration of $18,771,300, plus the
adjustments described in Section 1.9, as applicable (the "Merger
Consideration"). Subject to the terms and conditions set forth in this
Agreement, as of the Effective Time of the Merger, by virtue of the Merger and
without any action on the part of the holders of shares of the Class A Common
stock, $.10 par value per share, of Temroc (the "Class A Stock"), the holders of
shares of the Class B Common stock, $.10 par value, of Temroc (the "Class B
Stock" and, together with the Class A Stock, the "Temroc Stock") or Parent, as
the sole stockholder of Sub:

                  (a) each share of Class A Stock outstanding immediately before
the Effective Time shall be converted at the Effective Time into the right to
receive in cash $291.99 per share (the "Class A Consideration") plus the
allocable portion of the purchase price adjustment described in Section 1.9;

                  (b) each share of Class B Stock outstanding immediately before
the Effective Time shall be converted at the Effective Time into the right to
receive in cash $583.98 per share



                                       2
   15

(the "Class B Consideration") plus the allocable portion of the purchase price
adjustment described in Section 1.9.

                  (c) each share of Sub's common stock, $.01 par value per share
(the "Sub Stock"), outstanding immediately before the Effective Time shall
remain outstanding and constitute one share of common stock, $.01 par value per
share, of the Surviving Corporation.

         As of and after the Effective Time, except as set forth in Section 1.7,
no holder of any certificate that immediately before the Effective Time
represented shares of Temroc Stock shall have any rights as a shareholder of
Temroc other than to receive the applicable Merger Consideration and the
allocable portion of the Escrow Consideration, in accordance with the terms of
this Agreement. Immediately after the Effective Time, Parent shall be the sole
shareholder of the Surviving Corporation.

                  1.7 SHARES OF DISSENTING SHAREHOLDERS. Notwithstanding
anything in this Agreement to the contrary, any issued and outstanding shares of
Temroc Stock held by persons who object to the Merger and comply with all the
provisions of the Minnesota Act concerning the right of holders of Temroc Stock
to dissent from the Merger and require appraisal of their shares of Temroc Stock
(each a "Dissenting Shareholder" and, collectively, the "Dissenting
Shareholders"), shall not be converted as described in Section 1.6 but shall
only be entitled to such rights as are granted by the Minnesota Act; provided,
however, that shares of Temroc Stock outstanding immediately prior to the
Effective Time of the Merger and held by a Dissenting Shareholder who shall,
after the Effective Time of the Merger, withdraw his demand for appraisal or
lose his right of appraisal, shall be deemed to be converted, as of the
Effective Time of the Merger, only into the right to receive the Merger
Consideration. Temroc shall give Sub prompt notice of any written demands for
appraisal of shares of Temroc Stock received by Temroc. The Surviving
Corporation shall make any and all payments due to Dissenting Shareholders.

                  1.8 ADDITIONAL ESCROW CONSIDERATION. In reliance on the
representations and warranties of Temroc contained in this Agreement, and on the
terms and subject to the conditions set forth in this Agreement, Sub shall pay,
as additional consideration for the Merger, $900,000 (the "Escrow
Consideration") by wire transfer of immediately available funds to an escrow
account under the terms of an escrow agreement in substantially the form of
Exhibit D (the "Escrow Agreement").

                  1.9 PURCHASE PRICE ADJUSTMENTS.

                  (a) PURCHASE PRICE ADJUSTMENT AT CLOSING. The Net Asset Value
as of December 31, 1999 was $5,227,368. If, based on Temroc's financial
statements as of July 31, 2000, the Net Asset Value as of July 31, 2000 exceeds
$5,227,368, then Parent shall pay at Closing, in addition to the Merger
Consideration, an amount equal to such excess (the "Additional Closing
Consideration"). If the Net Asset Value as of July 31, 2000 does not exceed
$5,227,368, then Parent shall not pay any amount in addition to the Merger
Consideration at the time of the Closing. Any cash proceeds received by Temroc
pursuant to the disposition of its interests in the Partnerships and the stock
of Aacron will be in addition to the Merger Consideration and shall be
distributed to the shareholders of Temroc at the Closing.

   16

                  (b) PREPARATION OF THE POST-CLOSING DATE BALANCE SHEET. Within
sixty (60) calendar days after the Closing, Parent shall cause the accounting
firm of Deloitte & Touche LLP to prepare an audited balance sheet of Temroc as
of the Closing Time (the "Closing Date Balance Sheet"). The Closing Date Balance
Sheet shall be prepared in accordance with generally accepted accounting
principles ("GAAP") applied on a basis consistent with the preparation of
Temroc's financial statements as of December 31, 1999 and for the twelve months
then ended, subject to such interpretations and modifications of GAAP as are set
forth on SCHEDULE 1.9(b). Parent shall cause a copy of the Closing Date Balance
Sheet to be delivered to Elmer Schumer (the "Temroc Representative") promptly
upon its completion.

                  (c) PROCEDURE FOR OBJECTING TO AND FINALLY DETERMINING THE
CLOSING DATE BALANCE SHEET. If the Temroc Representative has not given any
notice of objection with respect to the Closing Date Balance Sheet within ten
(10) calendar days after its receipt by the Temroc Representative, then the
calculation of the Closing Date Net Asset Value described in this Section 1.9
shall be based on the Closing Date Balance Sheet. If, however, the Temroc
Representative has given a notice of objection with respect to the Closing Date
Balance Sheet within such ten (10) calendar day period, then the Temroc
Representative and Parent shall attempt to resolve their differences. If the
Temroc Representative and Parent cannot agree on appropriate changes to be made
to the Closing Date Balance Sheet within fifteen (15) business days after the
Temroc Representative has delivered his notice of objection, then the Temroc
Representative and Parent shall submit the Closing Date Balance Sheet, along
with the written objections of the Temroc Representative and Parent, to KPMG LLP
(the "Alternate Accounting Firm"). The Temroc Representative and Parent shall
request the Alternate Accounting Firm to determine only those aspects of the
Closing Date Balance Sheet that are in controversy and to make that
determination in accordance with the terms of this Agreement within 30 days
after the request. The Alternate Accounting Firm shall make its determination
based solely on presentations by the Temroc Representative and Parent, and not
by independent review, and its determination shall be conclusive and binding
upon the parties and unreviewable by any court. In resolving any disputed item,
the Alternate Accounting Firm (1) shall be bound by the provisions of Section
1.9(b) and (2) may not assign a value to any item greater than the greatest
value for such item claimed by either party or less than the smallest value for
such item claimed by either party. The Closing Date Net Asset Value described in
this Section 1.9 shall then be based on the Closing Date Balance Sheet as
adjusted to take into account the Alternate Accounting Firm's determinations of
those matters that are in controversy. Any fees of the Alternate Accounting Firm
(1) shall be borne by Parent in the proportion that the aggregate dollar amount
of such disputed items so submitted that are unsuccessfully disputed by Parent
bears to the aggregate dollar amount of such items so submitted and (2) shall be
borne by the Temroc Representative (out of the funds deposited into the escrow
account under the Escrow Agreement described in Section 1.8) in the proportion
that the aggregate dollar amount of such disputed items so submitted that are
successfully disputed by Parent bears to the aggregate dollar amount of such
items so submitted. Parent and the Temroc Representative shall make available to
the other their respective work papers generated in connection with the
preparation or review of the Closing Date Balance Sheet.

                  (d) PAYMENT OF ADJUSTMENT AMOUNT. If the Net Asset Value,
based on the Closing Date Balance Sheet (the "Closing Date Net Asset Value"), is
greater than the sum of



                                       4
   17

$5,227,368 and the Additional Closing Consideration, Parent shall pay the Temroc
shareholders an Adjustment Amount equal to the excess of the Net Asset Value
over the sum of $5,227,368 and the Additional Closing Consideration, plus
interest on such excess amount based on an annual rate of 7.5% from the date of
the Closing until the date of payment by the Parent. If the Net Asset Value is
less than the sum of $5,227,368 and the Additional Closing Consideration, the
Escrow Agent (as defined in the Escrow Agreement) shall pay Parent an Adjustment
Amount equal to the excess of the sum of $5,227,368 and the Additional Closing
Consideration over the amount of the Closing Date Net Asset Value, plus interest
on the Additional Closing Consideration based on an annual rate of 7.5%, from
the date of the Closing until the date of payment by the Escrow Agent. An
illustration of the calculation required by this Section 1.9(d) is set forth on
SCHEDULE 1.9(d). The Adjustment Amount shall be paid within five (5) business
days after its determination in accordance with this Section 1.9. The Adjustment
Amount shall be payable by wire transfer of immediately available funds to the
account designated in writing by the party to receive it.

                  (e) DEFINITION OF NET ASSET VALUE. For purposes of this
Agreement, "Net Asset Value" means the excess of the total assets of Temroc,
(exclusive of intercompany accounts), as shown on the Balance Sheet for July 31,
2000 or the Closing Date Balance Sheet as applicable, over the total liabilities
of Temroc as shown on the Balance Sheet for July 31, 2000, or the Closing Date
Balance Sheet, as applicable. Transactions between Temroc and Aacron or any
Partnership reflected on the Closing Date Balance Sheet shall not be treated as
intercompany accounts.

         2. CLOSING.

                  2.1 TIME AND PLACE OF THE CLOSING. Subject to the satisfaction

organized, validly existing and in good standing under the laws of the State of
Minnesota and has the corporate power and authority to own, operate and lease
its properties and carry on its business as now owned, operated, leased or
conducted. To the extent Temroc does business outside its jurisdiction of
incorporation, it is duly qualified to conduct its business and is in good
standing in such jurisdictions, each of which is listed on SCHEDULE 3.1 attached
hereto, except where the failure to be so qualified would not have a material
adverse effect on the operations or financial condition of Temroc. True and
correct copies of the articles of incorporation and the bylaws of Temroc as in
effect on the date of this Agreement have been provided to Parent.

                  3.2 AUTHORITY, CAPACITY AND ENFORCEABILITY. Temroc has all
requisite corporate power and authority to enter into, deliver and perform this
Agreement and any other agreement or document necessary to perform this
Agreement and to consummate the Merger and other transactions described in this
Agreement. This Agreement has been duly executed and delivered by Temroc
pursuant to all necessary corporate action. Assuming the due authorization,
execution and delivery by Parent and Sub, this Agreement constitutes the legal,
valid and binding obligation of Temroc, enforceable against Temroc in accordance
with its terms, except as may be limited by principles of equity or bankruptcy,
insolvency, reorganization, moratorium or similar laws or judicial decisions
relating to or affecting the enforcement of creditors' rights or equitable
remedies.

                  3.3 CAPITALIZATION. The authorized capital stock of Temroc
consists of 100,000 shares of Class A Stock, 56,948 shares of which are issued
and outstanding, and 60,000 shares of Class B Stock, 3,670 shares of which are
issued and outstanding. Each issued and outstanding share of Class A Stock and
each issued and outstanding share of Class B Stock is duly authorized, validly
issued, fully paid and nonassessable and has not been issued, and is not owned
or held, in violation of any preemptive right of shareholders or other persons.
All issued and outstanding shares of the Class A Stock and Class B Stock are
owned of record by the persons and in the amounts set forth on SCHEDULE 3.3, and
to Temroc's knowledge, except as set forth on SCHEDULE 3.3, all such shares are
free and clear of all liens, judgments, claims, security interest, pledges,
attachments, mortgages, restrictions on transfer and encumbrances
("Encumbrances"), stockholders' agreements and voting trusts, and there are no
other beneficial owners of that stock. Except pursuant to this Agreement, there
is no commitment, plan or arrangement to issue, and no outstanding option,
warrant or other right calling for the issuance of, any share of capital stock
of Temroc, or any security or other instrument convertible into, or exercisable
or exchangeable for, capital stock of Temroc. No security or other instrument
convertible into or exchangeable for capital stock of Temroc is issued and
outstanding.

                  3.4 INTERESTS IN OTHER ENTITIES AND SCOPE OF BUSINESS. Except

"Facilities"). Temroc has not engaged in any activities and has not conducted
any operations other than those activities and operations that are incident to
the Business.

                  3.5 NO CONFLICT. Neither the execution and delivery by Temroc
of this Agreement, the consummation of the Merger and the transactions described
in this Agreement by Temroc nor compliance by Temroc with any of the provisions
of this Agreement will violate, conflict with, result in a breach of or
constitute a default under (a) Temroc's articles of incorporation or bylaws, (b)
any material contracts, commitments or agreements to which Temroc is a party or
by which any assets of Temroc are bound, (c) any law, statute, code, act,
ordinance, order, judgment, decree, injunction, rule, regulation, permit,

as defined in Section 3.10 (collectively, "Legal Requirements"), by which Temroc
is subject or bound, or (d) any Environmental Law, as defined in Section 3.10,
by which Temroc is subject or bound.

the same terms and conditions as currently apply, assuming that there is no
material change in the nature of the Business after the Closing Time. To the

periods extending beyond their terminations of employment, other than coverage
mandated by the Consolidated Omnibus Budget Reconciliation Act of 1985, as

medical, surgical, hospitalization or life insurance coverage for any current or

compensation due any such employee or officer by Temroc.

proposed Alternative Transaction or a reasonably detailed description of any
such information requested from it after the date hereof or of any such
negotiations or discussions being sought to be initiated or continued with the
Company after the date hereof in respect of a proposed Alternative Transaction.

The foregoing notwithstanding, this Agreement shall not prohibit the Board of
Directors of Temroc from, prior to the vote of Temroc's shareholders, furnishing
nonpublic information to or entering into discussions or negotiations with, any
person or entity that makes an unsolicited Superior Proposal (as defined below),
if, and only to the extent that:

                  (a) the Board of Directors reasonably and in good faith
determines that failure to take such action would be inconsistent with the
fiduciary duties of the Board of Directors to its stockholders under applicable
law, based on written advice from legal counsel for Temroc, a copy of which is
provided to Parent;

                  (b) prior to first furnishing nonpublic information to, or
first entering into any substantive discussions and negotiations with, such
person or entity after the date hereof, Temroc provides written notice to Parent
to the effect that it intends to furnish information to, or enter into
discussions or negotiations with, a person or entity making a Superior Proposal,
and naming and identifying the person or entity making the Superior Proposal;

                  (c) Temroc provides Parent with all non-public information to
be provided to such person or entity which Parent has not previously received
from Temroc, and Temroc keeps Parent informed, on a regular basis, of the
status, terms and conditions and all other material information with respect to
any such discussions or negotiations.

Nothing in this Section 5.10 shall (x) permit Temroc to terminate this Agreement
(except as specifically provided in Article 8 hereof), or (y) permit Temroc to
enter into any agreement providing for an Alternative Transaction (other than as
specifically provided in Article 8 hereof, and in the circumstances and under
the conditions set forth, above) for as long as this Agreement remains in
effect.

For purposes of this Agreement, a "Superior Proposal" shall mean a proposal for
an Alternative Transaction that the Board of Directors of Temroc has reasonably
and in good faith determined (with the advice of its financial advisors and
taking into account all legal, financial and regulatory aspects of the
likelihood of the consummation of such Alternative Transaction, including, but
not limited to, the conditions to consummation and the consequences under such
Alternative Transaction proposal of any material adverse effects or changes in
Temroc) to be more favorable to Temroc's shareholders than the transactions
contemplated by this Agreement.

                  5.11 EMPLOYEE BENEFITS. All employees of Temroc shall receive
recognition for their service with Temroc for purposes of seniority, eligibility
to participate, eligibility for benefits and vesting under any plans, agreements
or arrangements of Parent to which those employees may become eligible for after
Closing. Parent shall take into account, under the employee benefit plans of
Parent, any medical or dental welfare expenses incurred under any plan of Temroc
during the plan year or other coverage period in which those employees are first



                                       24
   37

provided coverage under the employee benefit plans of Parent, for purposes of
satisfying applicable deductible, coinsurance and maximum out-of-pocket
provisions.

                  5.12 QUANEX NONCOMPETITION COVENANT. For a period of three (3)
years following the Closing, Parent shall not, directly or indirectly, engage or
invest in, own, manage, operate, finance, control, or participate in the
ownership, management, operation, financing, or control of, be associated with,
or in any manner connected with, lend the name of Quanex or any similar name to,
lend credit to, or render services or advice to, any anodizing business located
in the states of Illinois, Iowa, Minnesota, North Dakota, South Dakota or
Wisconsin. Notwithstanding the foregoing sentence, Parent or any of its
affiliates may acquire any business in the above-described geographical areas
and own, manage, operate, finance, control and participate in the ownership,
management, operation, financings and control of the business, be associated
with the business, lend its name to the business, lend credit to the business
and render services or advice to the business, if at the time of the acquisition
of the business, less than 20% of its revenues for its last fiscal year were
attributable to providing anodizing services.

                  5.13 RELATIONSHIP WITH AACRON. For a period of three years
following the Closing, Parent will cause the Surviving Corporation to cooperate
with Aacron to continue and maintain the business relationship between the two
companies as it exists as of the date of Closing; provided, however, that this
Section 5.13 shall not be deemed to require either Parent or the Surviving
Corporation to conduct business with Aacron with respect to (i) any existing
customer of Temroc if Aacron cannot or does not continue to provide services to
that customer meeting current standards with respect to that customer, (ii) any
new customers of the Surviving Corporation if there is a commercially compelling
reason to conduct the business relationship with a third party after Aacron has
had an opportunity to bid on the business project with the third party or (iii)
any customers of the Surviving Corporation if the business project involves
technologies that differ from those currently used by Aacron.

                  (f) By either Parent or Temroc if, at the Temroc shareholders'

date in the event of termination pursuant to Section 8.1(g) (by wire transfer of

         SECTION 2.04. Special Meeting. Special meetings of the shareholders,
for any purpose or purposes, unless otherwise prescribed by statute or by the
Articles of Incorporation, may be called by the Chairman of the Board or by the
President of the corporation or by the Board of Directors or by written order of
a majority of the directors and shall be called by the President or the
Secretary at the request in writing of shareholders owning a majority in amount
of the entire capital stock of the corporation issued and outstanding and
entitled to vote. Such request shall state the purposes of the proposed meeting.
The Chairman of the Board or the President of the corporation or directors so
calling, or the shareholders so requesting, any such meeting shall fix the time
and any place, either within or without the State of Minnesota, as the place for
holding such meeting.

         SECTION 2.05. Notice of Meeting. Written notice of the annual, and each
special meeting of shareholders, stating the time, place, and purpose or
purposes thereof, shall be given to each shareholder entitled to vote thereat,
not less than 10 nor more than 60 days before the meeting.

         SECTION 2.06. Quorum. The holders of a majority of the shares of the
corporation's capital stock issued and outstanding and entitled to vote thereat,
present in person or represented by proxy, shall constitute a quorum at any
meeting of shareholders for the transaction of business, except as otherwise
provided by statute or by the Articles of Incorporation. Notwithstanding the
other provisions of the Articles of Incorporation or these bylaws, the holders
of a majority of the shares of the corporation's capital stock entitled to vote
thereat, present in person or represented by proxy, whether or not a quorum is
present, shall have power to adjourn the meeting from time to time, without
notice other than announcement at the meeting, until a quorum shall be present
or represented. If the adjournment is for more than 30 days, or if after the
adjournment a new record date is fixed for the adjourned meeting, a notice of
the adjourned meeting shall be given to each shareholder of record entitled to
vote at the meeting. At such adjourned meeting at which a quorum shall be
present or represented, any business may be transacted which might have been
transacted at the meeting as originally notified.

         SECTION 2.07. Voting. When a quorum is present at any meeting of the
shareholders, the vote of the holders of a majority of the shares of the
corporation's capital stock having voting power present in person or represented
by proxy shall decide any question brought before such meeting, unless the
question is one upon which, by express provision of the statutes, of the
Articles of Incorporation or of these bylaws, a different vote is required, in
which case such express provision shall govern and control the decision of such
question. Every shareholder having the right to vote shall be entitled to vote
in person, or by proxy appointed by an instrument in writing subscribed by such
shareholder, bearing a date not more than three years prior to voting, unless
such instrument provides for a longer period, and filed with the Secretary of
the corporation before, or at the time of, the meeting. If such instrument shall
designate two or more persons to act as proxies, unless such instrument shall
provide the contrary, a majority of such persons present at any meeting at which
their powers thereunder are to be exercised shall have and may exercise all the
powers of voting or giving consents thereby conferred, or if only one be
present, then such powers may be exercised by that one; or, if an even number
attend and a majority do not agree on any particular issue, each proxy so
attending shall be entitled to

                                       2
   58


exercise such powers in respect of the same portion of the shares as he is of
the proxies representing such shares.

         SECTION 2.08. Consent of Shareholders. Whenever the vote of
shareholders at a meeting thereof is required or permitted to be taken for or in
connection with any corporate action by any provision of the statutes, the
meeting and vote of shareholders may be dispensed with if all the shareholders
who would have been entitled to vote upon the action if such meeting were held
shall consent in writing to such corporate action being taken.

         SECTION 2.09. Voting of Stock of Certain Holders. Shares of the
corporation's capital stock standing in the name of another corporation,
domestic or foreign, may be voted by such officer, agent, or proxy as the bylaws
of such corporation may prescribe, or in the absence of such provision, as the
Board of Directors of such corporation may determine. Shares standing in the
name of a deceased person may be voted by the executor or administrator of such
deceased person, either in person or by proxy. Shares standing in the name of a
guardian, conservator, or trustee may be voted by such fiduciary, either in
person or by proxy, but no such fiduciary shall be entitled to vote shares held
in such fiduciary capacity without a transfer of such shares into the name of
such fiduciary. Shares standing in the name of a receiver may be voted by such
receiver. A shareholder whose shares are pledged shall be entitled to vote such
shares, unless in the transfer by the pledgor on the books of the corporation,
he has expressly empowered the pledgee to vote thereon, in which case only the
pledgee, or his proxy, may represent the stock and vote thereon.

         SECTION 2.10. Authorized, but Unissued Stock. The corporation shall not
vote, directly or indirectly, shares of its own capital stock owned by it; and
such shares shall not be counted in determining the total number of outstanding
shares of the corporation's capital stock.

         SECTION 2.11. Fixing Record Date. The Board of Directors may fix in
advance a date, which shall not be more than 60 days nor less than 10 days
preceding the date of any meeting of shareholders, nor more than 60 days
preceding the date for payment of any dividend or distribution, or the date for
the allotment of rights, or the date when any change, or conversion or exchange
of capital stock shall go into effect, or a date in connection with obtaining a
consent, as a record date for the determination of the shareholders entitled to
notice of, and to vote at, any such meeting and any adjournment thereof, or
entitled to receive payment of any such dividend or distribution, or to receive
any such allotment of rights, or to exercise the rights in respect of any such
change, conversion or exchange of capital stock, or to give such consent, and in
such case such shareholders and only such shareholders as shall be shareholders
of record on the date so fixed, shall be entitled to such notice of, and to vote
at, any such meeting and any adjournment thereof, or to receive payment of such
dividend or distribution, or to receive such allotment of rights, or to exercise
such rights, or to give such consent, as the case may be, notwithstanding any
transfer of any stock on the books of the corporation after any such record date
fixed as aforesaid.

                               BOARD OF DIRECTORS

         SECTION 3.01. Powers. The business and affairs of the corporation shall
be managed by its Board of Directors, which may exercise all such powers of the
corporation and do all such lawful acts and things as are not by statute or by
the Articles of Incorporation or by these bylaws directed or required to be
exercised or done by the shareholders.

         SECTION 3.02. Number, Election and Term. The number of directors that
shall constitute the whole Board of Directors shall be not less than one. Such
number of directors shall from time to time be fixed and determined by the
directors and shall be set forth in the notice of any meeting of shareholders
held for the purpose of electing directors. The directors shall be elected at
the annual meeting of shareholders, except as provided in Section 3.03, and each
director elected shall hold office until his successor shall be elected and
shall qualify. Directors need not be residents of Minnesota or shareholders of
the corporation.

         SECTION 3.03. Vacancies, Additional Directors, and Removal From Office.
If any vacancy occurs in the Board of Directors caused by death, resignation,
retirement, disqualification, or removal from office of any director, or
otherwise, or if any new directorship is created by an increase in the
authorized number of directors, a majority of the directors then in office,
though less than a quorum, or a sole remaining director, may choose a successor
or fill the newly created directorship; and a director so chosen shall hold
office until the next election and until his successor shall be duly elected and
shall qualify, unless sooner displaced. Any director may be removed either for
or without cause at any special meeting of shareholders duly called and held for
such purpose.

         SECTION 3.04. Regular Meeting. A regular meeting of the Board of
Directors shall be held each year, without other notice than this bylaw, at the
place of, and immediately following, the annual meeting of shareholders; and
other regular meetings of the Board of Directors shall be held each year, at
such time and place as the Board of Directors may provide, by resolution, either
within or without the State of Minnesota, without other notice than such
resolution.

         SECTION 3.05. Special Meeting. A special meeting of the Board of
Directors may be called by the Chairman of the Board of Directors or by the
President of the corporation and shall be called by the Secretary on the written
request of any two directors. The Chairman or President so calling, or the
directors so requesting, any such meeting shall fix the time and any place,
either within or without the State of Minnesota, as the place for holding such
meeting.

         SECTION 3.06. Notice of Special Meeting. Written notice of special
meetings of the Board of Directors shall be given to each director at least 48
hours prior to the time of such meeting. Any director may waive notice of any
meeting. The attendance of a


                                       4
   60


director at any meeting shall constitute a waiver of notice of such meeting,
except where a director attends a meeting for the purpose of objecting to the
transaction of any business because the meeting is not lawfully called or
convened. Neither the business to be transacted at, nor the purpose of, any
special meeting of the Board of Directors need be specified in the notice or
waiver of notice of such meeting, except that notice shall be given of any
proposed amendment to the bylaws if it is to be adopted at any special meeting
or with respect to any other matter where notice is required by statute.

         SECTION 3.07. Quorum. A majority of the Board of Directors shall
constitute a quorum for the transaction of business at any meeting of the Board
of Directors, and the act of a majority of the directors present at any meeting
at which there is a quorum shall be the act of the Board of Directors, except as
may be otherwise specifically provided by statute, by the Articles of
Incorporation or by these bylaws. If a quorum shall not be present at any
meeting of the Board of Directors, the directors present thereat may adjourn the
meeting from time to time, without notice other than announcement at the
meeting, until a quorum shall be present.

         SECTION 3.08. Action Without Meeting. Unless otherwise restricted by
the Articles of Incorporation or these bylaws, any action required or permitted
to be taken at any meeting of the Board of Directors, or of any committee
thereof as provided in Article IV of these bylaws, may be taken without a
meeting, if a written consent thereto is signed by all members of the Board of
Directors or of such committee, as the case may be, unless the action is one
which need not be approved by the shareholders, in which case such action shall
be effective if signed by the number of directors that would be required to take
the same action at a meeting at which all directors were present, and such
written consent is filed with the minutes of proceedings of the Board of
Directors or such committee.

         SECTION 3.09. Compensation. Directors, as such, shall not be entitled
to any stated salary for their services unless voted by the shareholders or the
Board of Directors; but by resolution of the Board of Directors, a fixed sum
and expenses of attendance, if any, may be allowed for attendance at each
regular or special meeting of the Board of Directors or any meeting of a
committee of directors. No provision of these bylaws shall be construed to
preclude any director from serving the corporation in any other capacity and
receiving compensation therefor.

                                   ARTICLE IV

                             COMMITTEES OF DIRECTORS

         SECTION 4.01. Designation, Powers and Name. The Board of Directors may,
by resolution passed by a majority of the whole Board of Directors, designate
one or more committees, including, if they shall so determine, an Executive
Committee, each such committee to consist of two or more of the directors of the
corporation. The committee shall have and may exercise such of the powers of the
Board of Directors in the management of the business and affairs of the
corporation as may be provided in such resolution. The committee may authorize
the seal of the corporation to be affixed to all papers that may require it. The
Board of Directors may designate one or more directors as alternate members of
any committee, who may replace

                                       5
   61


any absent or disqualified member at any meeting of such committee. In the
absence or disqualification of any member of such committee or committees, the
member or members thereof present at any meeting and not disqualified from
voting, whether or not he or they constitute a quorum, may unanimously appoint
another member of the Board of Directors to act at the meeting in the place of
any such absent or disqualified member. Such committee or committees shall have
such name or names and such limitations of authority as may be determined from
time to time by resolution adopted by the Board of Directors.

         SECTION 4.02. Minutes. Each committee of directors shall keep regular
minutes of its proceedings and report the same to the Board of Directors when
required.

         SECTION 4.03. Compensation. Members of special or standing committees
may be allowed compensation for attending committee meetings, if the Board of
Directors shall so determine.

                                     NOTICE

         SECTION 5.01. Methods of Giving Notice. Whenever under the provisions
of applicable statutes, the Articles of Incorporation or these bylaws, notice is
required to be given to any director, member of any committee, or shareholder,
such notice shall be in writing and delivered personally or mailed to such
director, member, or shareholder; provided that in the case of a director or a
member of any committee such notice may be given orally or by telephone or
telegram. If mailed, notice to a director, member of a committee, or shareholder
shall be deemed to be given when deposited in the United States mail first class
in a sealed envelope, with postage thereon prepaid, addressed, in the case of a
shareholder, to the shareholder at the shareholder's address as it appears on
the records of the corporation or, in the case of a director or a member of a
committee, to such person at his business address. If sent by telegraph, notice
to a director or member of a committee shall be deemed to be given when the
telegram, so addressed, is delivered to the telegraph company.

         SECTION 5.02. Waiver. Whenever any notice is required to be given under
the provisions of an applicable statute, the Articles of Incorporation, or these
bylaws, a waiver thereof in writing, signed by the person or persons entitled to
said notice, whether before or after the time stated therein, or attendance at
any meeting, shall be deemed equivalent thereto.

         SECTION 8.01. Issuance. Each shareholder of this corporation shall be
entitled to a certificate or certificates showing the number of shares of
capital stock registered in his name on the books of the corporation. The
certificates shall be in such form as may be determined by the Board of
Directors, shall be issued in numerical order and shall be entered in the books
of the corporation as they are issued. They shall exhibit the holder's name and
number of shares and shall be signed by the President or a Vice President and by
the Secretary or an Assistant Secretary. If any certificate is countersigned (1)
by a transfer agent other than the corporation or any employee of the
corporation, or (2) by a registrar other than the corporation or any employee of
the corporation, any other signature on the certificate may be a facsimile. If
the corporation shall be authorized to issue more than one class of stock or
more than one series of any class, the designations, preferences, and relative
participating, optional, or other special rights of each class of stock or
series thereof and the qualifications, limitations, or restrictions of such
preferences and rights shall be set forth in full or summarized on the face or
back of the certificate which the corporation shall issue to represent such
class of stock; provided that, except as otherwise provided by statute, in lieu
of the foregoing requirements there may be set forth on the face or back of the
certificate which the corporation shall issue to represent such class or series
of stock, a statement that the corporation will furnish to each shareholder who
so


                                       10
   66



requests the designations, preferences and relative, participating, optional or
other special rights of each class of stock or series thereof and the
qualifications, limitations, or restrictions of such preferences and rights. All
certificates surrendered to the corporation for transfer shall be canceled and
no new certificate shall be issued until the former certificate for a like
number of shares shall have been surrendered and canceled, except that in the
case of a lost, stolen, destroyed, or mutilated certificate a new one may be
issued therefor upon such terms and with such indemnity, if any, to the
corporation as the Board of Directors may prescribe. Certificates shall not be
issued representing fractional shares of stock.

         SECTION 8.02. Lost Certificates. The Board of Directors may direct a
new certificate or certificates to be issued in place of any certificate or
certificates theretofore issued by the corporation alleged to have been lost,
stolen, or destroyed, upon the making of an affidavit of that fact by the person
claiming the certificate of stock to be lost, stolen or destroyed. When
authorizing such issue of a new certificate or certificates, the Board of
Directors may, in its discretion and as a condition precedent to the issuance
thereof, require (1) the owner of such lost, stolen, or destroyed certificate or
certificates, or his legal representative, to advertise the same in such manner
as it shall require, (2) such owner to give the corporation a bond in such sum
as it may direct as indemnity against any claim that may be made against the
corporation with respect to the certificate or certificates alleged to have been
lost, stolen, or destroyed, or (3) both.

         SECTION 8.03. Transfers. Upon surrender to the corporation or the
transfer agent of the corporation of a certificate for shares duly endorsed or
accompanied by proper evidence of succession, assignment, or authority to
transfer, it shall be the duty of the corporation to issue a new certificate to
the person entitled thereto, cancel the old certificate, and record the
transaction upon its books. Transfers of shares shall be made only on the books
of the corporation by the registered holder thereof, or by his attorney
thereunto authorized by power of attorney and filed with the Secretary of the
corporation or the Transfer Agent.

         SECTION 8.04. Registered Shareholders. The corporation shall be
entitled to treat the holder of record of any share or shares of the
corporation's capital stock as the holder in fact thereof and, accordingly,
shall not be bound to recognize any equitable or other claim to or interest in
such share or shares on the part of any other person, whether or not it shall
have express or other notice thereof, except as otherwise provided by the laws
of the State of Minnesota.

                                   ARTICLE IX

                                    DIVIDENDS

         SECTION 9.01. Declaration. Dividends with respect to the shares of the
corporation's capital stock, subject to the provisions of the Articles of
Incorporation, if any, may be declared by the Board of Directors at any regular
or special meeting, pursuant to applicable law. Dividends may be paid in cash,
in property, or in shares of capital stock, subject to the provisions of the
Articles of Incorporation.


                                       11
   67


         SECTION 9.02. Reserve. Before payment of any dividend, there may be set
aside out of any funds of the corporation available for dividends such sum or
sums as the Board of Directors from time to time, in their absolute discretion,
think proper as a reserve or reserves to meet contingencies, or for equalizing
dividends, or for repairing or maintaining any property of the corporation, or
for such other purpose as the Board of Directors shall think conducive to the
interest of the corporation, and the Board of Directors may modify or abolish
any such reserve in the manner in which it was created.

                                    ARTICLE X

                                 INDEMNIFICATION

         SECTION 10.01. Third Party Actions. The corporation shall indemnify any
director or officer of the corporation, and may indemnify any other person, who
was or is a party or is threatened to be made a party to any threatened,
pending, or completed action, suit, or proceeding, whether civil, criminal,
administrative or investigative (other than an action by or in the right of the
corporation) by reason of the fact that he is or was a director, officer,
employee, or agent of the corporation, or is or was serving at the request of
the corporation as a director, officer, employee, or agent of another
corporation, partnership, joint venture, trust, or other enterprise, against
expenses (including attorneys' fees), judgments, fines, and amounts paid in
settlement actually and reasonably incurred by him in connection with such
action, suit, or proceeding if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. The termination of any
action, suit, or proceeding by judgment, order, settlement, or conviction, or
upon a plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which he
reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had
reasonable cause to believe that his conduct was unlawful.

         SECTION 10.02. Actions by or in the Right of the Corporation. The
corporation shall indemnify any director or officer and may indemnify any other
person who was or is a party or is threatened to be made a party to any
threatened, pending, or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that he is
or was a director, officer, employee, or agent of the corporation, or is or was
serving at the request of the corporation as a director, officer, employee, or
agent of another corporation, partnership, joint venture, trust, or other
enterprise against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection with the defense or settlement of such action or
suit if he acted in good faith and in a manner he reasonably believed to be in
or not opposed to the best interests of the corporation and except that no
indemnification shall be made in respect of any claim, issue, or matter as to
which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the court in which such action or suit was
brought shall determine upon application that, despite the adjudication of
liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses as the court shall
deem proper.


                                       12
   68


         SECTION 10.03. Mandatory Indemnification. To the extent that a
director, officer, employee, or agent of the corporation has been successful on
the merits or otherwise in defense of any action, suit, or proceeding referred
to in Sections 10.01 and 10.02, or in defense of any claim, issue, or matter
therein, he shall be indemnified against expenses (including attorneys' fees)
actually and reasonably incurred by him in connection therewith.

         SECTION 10.04. Determination of Conduct. The determination that a
director, officer, employee, or agent has met the applicable standard of conduct
set forth in Sections 10.01 and 10.02 (unless indemnification is ordered by a
court) shall be made (1) by the Board of Directors by a majority vote of a
quorum consisting of directors who were not parties to such action, suit, or
proceeding, or (2) if such quorum is not obtainable, or, even if obtainable a
quorum of disinterested directors so directs, by independent legal counsel in a
written opinion, or (3) by the shareholders.

         SECTION 10.05. Payment of Expenses in Advance. Expenses incurred in
defending a civil or criminal action, suit, or proceeding shall be paid by the
corporation in advance of the final disposition of such action, suit, or
proceeding upon receipt of an undertaking by or on behalf of the director,
officer, employee, or agent to repay such amount if it shall ultimately be
determined that he is not entitled to be indemnified by the corporation as
authorized in this Article X.

         SECTION 10.06. Indemnity Not Exclusive. The indemnification and
advancement of expenses provided or granted hereunder shall not be deemed
exclusive of any other rights to which those seeking indemnification or
advancement of expenses may be entitled under the Articles of Incorporation, any
other bylaw, agreement, vote of shareholders, or disinterested directors or
otherwise, both as to action in his official capacity and as to action in
another capacity while holding such office.

         SECTION 10.07. Definitions. For purposes of this Article X:

     corporation, any constituent corporation (including any constituent of a
     constituent) absorbed in a consolidation or merger that, if its separate
     existence had continued, would have had power and authority to indemnify
     its directors, officers, and employees or agents, so that any person who is
     or was a director, officer, employee, or agent of such constituent
     corporation, or is or was serving at the request of such constituent
     corporation as a director, officer, employee, or agent of another
     corporation, partnership, joint venture, trust, or other enterprise, shall
     stand in the same position under this Article X with respect to the
     resulting or surviving corporation as he would have with respect to such
     constituent corporation if its separate existence had continued;

         (b) "other enterprises" shall include employee benefit plans;

         (c) "fines" shall include any excise taxes assessed on a person with

   69


         (d) "serving at the request of the corporation" shall include any
     service as a director, officer, employee, or agent of the corporation that
     imposes duties on, or involves services by, such director, officer,
     employee, or agent with respect to an employee benefit plan, its
     participants or beneficiaries; and

         (e) a person who acted in good faith and in a manner he reasonably
     believed to be in the interest of the participants and beneficiaries of an
     employee benefit plan shall be deemed to have acted in a manner "not
     opposed to the best interests of the corporation" as referred to in this
     Article X.

         SECTION 10.08. Continuation of Indemnity. The indemnification and
advancement of expenses provided or granted hereunder shall, unless otherwise
provided when authorized or ratified, continue as to a person who has ceased to
be a director, officer, employee, or agent and shall inure to the benefit of the
heirs, executors, and administrators of such a person.

                                   ARTICLE XI

_________________, 2000, among Quanex Corporation, a Delaware corporation
("Quanex"), Temroc Metals, Inc., a Minnesota corporation (the "Surviving
Corporation"), Elmer Schumer, as representative for the former shareholders of

Minnesota, a Minnesota state banking association (the "Escrow Agent");

                                   WITNESSETH:

         WHEREAS, Quanex, Quanex Five, Inc., a Delaware corporation ("Sub") and
Temroc Metals, Inc., a Minnesota corporation ("Temroc") have entered into an
Agreement and Plan of Merger dated October 23, 2000 (the "Merger Agreement"),
pursuant to which Sub will merge with and into Temroc, with Temroc surviving as
a wholly owned subsidiary of Quanex (the "Surviving Corporation");

         WHEREAS, the Merger Agreement provides that Sub is to pay $900,000 as
Additional Escrow Consideration to be placed in escrow;

         WHEREAS, Quanex, the Surviving Corporation and the Shareholder
Representative, on behalf of the former shareholders of Temroc and who are
listed on Exhibit A (the "Shareholders"), desire to enter into this Escrow
Agreement to create the escrow required by the Merger Agreement; and

         WHEREAS, Quanex and Sub have requested the Escrow Agent to act as the
escrow agent under this Escrow Agreement, and the Escrow Agent has agreed to do
so.

         NOW, THEREFORE, in consideration of the premises and for other good and
valuable consideration, the parties to this Escrow Agreement agree as follows:

         1. Effective Time. This Escrow Agreement shall be effective as of the
Effective Time of the Merger.

         2. Appointment of Escrow Agent. Quanex, the Surviving Corporation and

                                       1
   71

shall be under the sole and exclusive dominion and control of the Escrow Agent,
and neither Quanex, the Surviving Corporation nor the Shareholder Representative
shall have any right with respect to the Escrow Fund except as set forth in this
Escrow Agreement.

         4. Satisfaction of Claims with Escrow Fund.

                  (a) DISTRIBUTIONS TO PAY CLAIMS. At all times during the term
of this Escrow Agreement, the Escrow Fund will be retained by the Escrow Agent
and shall be distributed at any time, or from time to time, for the purpose of
paying any and all Claims (as defined below) pursuant to the terms of this
Escrow Agreement.

                  (b) THE ESCROW FUND. During the term hereof the Escrow Fund
shall be distributed at any time, or from time to time, for the purpose of
paying (1) any Adjustment Amount owed to Quanex or the Surviving Corporation
pursuant to Section 1.9 of the Merger Agreement, (2) any and all claims, losses,
costs, damages (whether actual, punitive or consequential and including strict
liability claims) or expenses of any kind or nature whatsoever, whether or not
the result of a third-party claim and including diminution in value, court
costs, attorneys' fees and expenses and consultants' fees and expenses (each, a
"Loss") that Quanex, the Surviving Corporation or any of their officers,
directors, employees, agents or affiliates (each, a "Quanex Indemnified Party")
shall suffer or incur arising out of or in connection with any breach of the
representations, warranties, covenants and agreements contained in the Merger
Agreement or in any document signed by Temroc referred to in Article 2 of the
Merger Agreement which was delivered by Temroc for the benefit of Quanex or the
Surviving Corporation (excluding the representations and warranties described in
Section 9(d), which expired at the Closing) (each a "Claim" and collectively,
the "Claims"), (3) any Loss that a Quanex Indemnified Party shall suffer or
incur arising out of the tax treatment, for federal and state law purposes, of
the sale, distribution or other transfer by Temroc of the stock of Aacron, Inc.
("Aacron") and Temroc's interests in the Medina Parks, Highway 55 and 18 and JGM
Energy Investments - Mon. Dak. -- 1981-3 Drilling Fund partnerships (the
"Partnerships") in accordance with the Merger Agreement, and (4) any Loss that a
Quanex Indemnified Party shall suffer or incur arising out of any liability or
obligation of Aacron or any of the Partnerships.

                  (c) DEFINITION AND SCOPE OF CLAIMS. A Claim shall include all
reasonable expenses, disbursements and advances, including reasonable attorneys'
fees, expenses and disbursements, incurred or made in the investigation, defense
or administration of a Claim by Quanex or the Surviving Corporation.
Notwithstanding anything contained in this Escrow Agreement to the contrary,
there shall be no obligation under this Agreement for indemnification or the
satisfaction of a Claim unless and until the aggregate amount of all Claims
exceeds $50,000, and then only for the amount of Claims in excess of $50,000.

                  (d) NOTICE AND PAYMENT OF CLAIMS. From time to time in
accordance with the terms of this Escrow Agreement, a Quanex Indemnified Party
may give written notice (the "Notice") of a Claim, including a description of
the nature and amount of the Adjustment Amount, Loss or other obligation for
which payment is requested, to the Shareholder Representative. A copy of the
Notice shall be contemporaneously provided to the Escrow Agent



                                       2
   72

and, if the Quanex Indemnified Party is a person other than Quanex, to Quanex.
The Shareholder Representative shall have a period of 15 days from the date of
receipt of the Notice in which the Shareholder Representative may make Quanex,
the Surviving Corporation and the Escrow Agent aware of, and attempt to settle,
any dispute the Shareholder Representative may have regarding the Claim. If the
Shareholder Representative has not notified Quanex and the Surviving Corporation
of any such dispute within that 15-day period, then Quanex shall so notify the
Escrow Agent and the Escrow Agent shall immediately disburse the amount of the
Claim to Quanex. If the Shareholder Representative has notified Quanex and the
Surviving Corporation of any such dispute within that 15-day period, then the
Shareholder Representative, Quanex and the Surviving Corporation shall instruct
the Escrow Agent to pay Quanex immediately any amount of the Claim that is not
in dispute. If Quanex believes it is entitled to additional funds beyond the
agreed upon amount, then Quanex shall commence an arbitration proceeding within
ten business days of receipt of the objection to the distribution. Unless
otherwise agreed to by all parties, the arbitration shall be conducted according
to the AAA Commercial Arbitration Rules and a hearing must be held within 45
days of the filing by Quanex. Quanex shall notify AAA that a decision must be
issued within 21 days of the conclusion of the hearing. The arbitration shall be
instituted to determine only the matter in dispute. The Shareholder
Representative shall cooperate fully with AAA and Quanex in causing the decision
to be issued on a timely basis. If there has been no determination of the
dispute within the period described above and the failure to obtain a
determination is due to any actions or inactions of the Shareholder
Representative, then (a) Quanex shall notify the Escrow Agent and the Escrow
Agent by submission of a sworn statement providing the amount to be distributed
and the facts and circumstances warranting distribution of the requested funds
and the Escrow Agent shall immediately disburse the disputed amount of the Claim
to Quanex, (b) the Shareholder Representative, Quanex and the Surviving
Corporation shall continue to resolve the dispute through the arbitration
process, and (c) to the extent that the arbitration decision is not in favor of
Quanex and the Surviving Corporation, Quanex shall repay to the Escrow Agent the
difference between the amount paid to Quanex under the foregoing clause (a) and
the amount to which Quanex is entitled under the arbitration decision.

         5. Investment of Escrow Fund.

                  (a) MEANS OF INVESTING. The Escrow Fund shall be invested by
the Escrow Agent in such investments as the Escrow Agent and the Shareholder
Representative shall agree upon from time to time. The foregoing
notwithstanding, such investments shall be in savings deposits, certificates of
deposit or government obligations.

                  (b) ALLOCATION OF INCOME. All income earned on the Escrow Fund
(the "Escrow Income") shall be paid in accordance with Section 6(c).

         6. Payment of Escrow Fund Amounts.

                  (a) PAYMENTS. If the amount in the Escrow Fund (excluding
Escrow Income) on an Applicable Date (as defined below) exceeds the sum of the
related Applicable Balance (as defined below) and the amount of any unpaid
Claims as of the Applicable Date, then the Escrow



                                       3
   73

Agent shall pay and distribute to the Shareholders (or cause the Paying Agent to
do so pursuant to the Paying Agent Agreement) the amount of that excess, unless
on or before the Applicable Date Quanex has given notice to the Shareholder
Representative and the Escrow Agent that Quanex is aware of a Claim with respect
to which it is unable to specify the amount of damages, in which case the Escrow
Agent shall make no payments to the Shareholders with respect to the Applicable
Date. For purposes of this Section 6(a), the "Applicable Dates" and the related
"Applicable Balances" are as follows:



                    Applicable Date                         Applicable Balance

                                                        
        ________, 2001 [one year after Closing]                  $800,000

       ________, 2002 [two years after Closing]                  $534,000

      ________, 2003 [three years after Closing]                 $268,000


On the fourth anniversary of the Closing (the "Termination Date"), the Escrow
Agent shall pay and distribute the remaining principal balance of the Escrow
Fund as of that date to the Shareholders unless (i) any Claims are then pending,
in which case the Escrow Agent shall retain in the Escrow Fund an amount equal
to the aggregate amount of those Claims and pay the balance, if any, to the
Shareholders or (ii) Quanex has given notice to the Shareholder Representative
and the Escrow Agent of any other Claim a Quanex Indemnified Party may have
under this Escrow Agreement with respect to which it is unable to specify the
amount of damages, in which case the entire amount of the Escrow Fund (excluding
Escrow Income) as of that date shall be retained by the Escrow Agent. Balances
retained in the Escrow Fund under clause (i) or (ii) of the immediately
preceding sentence shall not be distributed until the Escrow Agent receives
written instructions of Quanex and the Shareholder Representative, but in no
event shall any balance be retained in the Escrow Fund one year after the
Termination Date, regardless of whether any actual or potential Claim has been
resolved. Any of the Escrow Fund remaining after the resolution of all Claims,
including all matters relating to those Claims and counterclaims and other
claims arising out of those matters, described in clauses (i) and (ii) shall be
promptly distributed by the Escrow Agent to the Shareholders.

                  (b) ALLOCATION OF PAYMENTS AMONG SHAREHOLDERS. All
distributions to the Shareholders under this Escrow Agreement, including
distributions under Section 6(a), shall be made pro rata according to the
percentages set forth on Exhibit A.

                  (c) DISTRIBUTION OF INTEREST. During the period of any dispute
under Section 4(b), all interest earned on that part of the Escrow Fund which is
in dispute and which is ultimately determined to be payable to Quanex shall be
paid to Quanex concurrently with the payment of those funds to Quanex. Subject
to the foregoing sentence, the Shareholder Representative may request that the
Escrow Agent distribute to him all or a portion of any accrued interest held in
the Escrow Fund to pay the reasonable legal fees and expenses incurred by him in
connection with any dispute or defense of claims that he may undertake pursuant
to the terms of this Agreement. Except for interest on the Escrow Fund payable
in accordance with the



                                       4
   74

foregoing two sentences, all other interest earned on the Escrow Fund shall be
paid to the Shareholders on the Termination Date.

         7. Shareholder Representative. The Shareholders have irrevocably made,
constituted and appointed the Shareholder Representative as their agent and true
and lawful attorney-in-fact, for such person and in such person's name, (i) to
execute and deliver to the Buyer on behalf of all the Shareholders this Escrow
Agreement, and to take all other actions on behalf of all such Shareholders
which the Shareholder Representative deems appropriate in his discretion in
connection with this Escrow Agreement as effectively as such person could act
for himself, herself or itself, (ii) to receive all claim notices and all of the
notices and communications directed to such person under this Escrow Agreement
and to take any action (or to determine to take no action) with respect thereto
as the Shareholder Representative may deem appropriate in his discretion as
effectively as such person could act for himself, herself or itself, including,
without limitation, the settlement or compromise of any dispute relating to the
Escrow Agreement or the Escrow Fund, or any other dispute or controversy
relating to this Escrow Agreement, and (iii) to execute and deliver all
instruments and documents of every kind incident to the foregoing to all intents
and purposes and with the same effect as such person could do personally, and
each Shareholder has ratified and confirms as his, her or its own act, all that
the Shareholder Representative shall do or cause to be done pursuant to the
provisions hereof. Each Shareholder has further agreed to indemnify the
Shareholder Representative and to hold the Shareholder Representative harmless
against any loss, liability, cost or expense suffered or incurred without
negligent conduct or bad faith on the part of the Shareholder Representative and
arising out of or in connection with his duties as Shareholder Representative,
including the costs and expenses incurred by such Shareholder Representative in
defending against any claim of liability in connection herewith. The Shareholder
Representative is specifically authorized to reimburse himself for any and all
such loss, liability, cost or expense suffered or incurred without negligent
conduct or bad faith on the part of the Shareholder Representative out of any
portion of the Escrow Fund that becomes actually and finally payable and
distributable to Shareholders in accordance with the provisions of Section 6(a),
6(b) or 6(c) before such funds are disbursed or distributed to any of the
Shareholders.

         8. Rights and Duties of the Escrow Agent.

                  (a) GENERAL SCOPE AND LIMITATIONS. The duties of the Escrow
Agent under this Escrow Agreement shall be limited to the observance of the
provisions of this Escrow Agreement. The Escrow Agent will not be subject to, or
be obliged to recognize, any other agreement between Quanex, the Surviving
Corporation and the Shareholder Representative. The Escrow Agent shall not make
any payment or disbursement from or out of the Escrow Fund that is not
authorized pursuant to this Escrow Agreement. The Escrow Agent may rely on and
act based on any instrument received by it pursuant to the provisions of this
Escrow Agreement that it reasonably believes to be genuine and in conformity
with the requirements of this Escrow Agreement. The Escrow Agent will not be
liable for any error of judgment for any act done or any step taken by it in
good faith in compliance with the provisions of this Escrow Agreement, for any
mistake of fact or law or for anything that it might do or refrain from doing in
complying



                                       5

with this Escrow Agreement, except to the extent those actions shall be proved
to constitute gross negligence or willful misconduct on the part of the Escrow
Agent.

                  (b) INDEMNIFICATION OF THE ESCROW AGENT. Quanex, the Surviving
Corporation and the Shareholder Representative shall jointly and severally
indemnify and hold harmless the Escrow Agent from and against any and all
losses, costs, damages and expenses (including reasonable attorneys' fees) it
may sustain by reason of its services as Escrow Agent under this Escrow
Agreement, except those losses, costs, damages and expenses (including without
limitation reasonable attorneys' fees) incurred by reason of those acts or
omissions for which the Escrow Agent is liable or responsible under the last
sentence of Section 8(a).

                  (c) RESIGNATION OF ESCROW AGENT. The Escrow Agent may resign
from its duties under this Escrow Agreement by giving Quanex, the Surviving
Corporation and the Shareholder Representative not less than 30 days' prior
written notice of the effective date of its resignation (which effective date
shall be at least 30 days after the date the notice is given). If on or before
the effective date of the resignation, the Escrow Agent has not received written
instructions from the Surviving Corporation and the Shareholder Representative
regarding the transfer of the Escrow Fund to a substitute escrow agent, it may
institute a bill of interpleader and deposit the Escrow Fund with the registry
of a court of competent jurisdiction. The parties intend that a substitute
Escrow Agent will be appointed to fulfill the duties of the Escrow Agent under
this Escrow Agreement for the remaining term of this Escrow Agreement if the
Escrow Agent resigns.

                  (d) CONSULTATION WITH LEGAL COUNSEL. The Escrow Agent may
consult with its counsel or other counsel satisfactory to it in respect of any
question relating to its duties or responsibilities under this Escrow Agreement
and shall not be liable for any action taken, suffered or omitted by the Escrow
Agent in good faith on the advice of that counsel. The Escrow Agent may act
through its officers, employees, agents and attorneys.

         9. Fees and Expenses of the Escrow Agent. All fees of the Escrow Agent
for its services under this Escrow Agreement, together with any expenses
reasonably incurred by the Escrow Agent in connection with this Escrow
Agreement, shall be split, fifty percent (50%) being paid by Quanex and fifty
percent (50%) being paid from the Escrow Fund. The Escrow Agent's current fee
schedule is $800 on the execution and delivery of this Agreement and $800
annually thereafter.

         10. Notices. All notices, requests, demands and other communications
made in connection with this Escrow Agreement shall be in writing and shall be

______________, 2000

Attention: ______________

Re: Paying Agent Agreement

Ladies and Gentlemen:

         This letter confirms our understanding with you in regard to the merger
(the "Merger") of Quanex Five, Inc., a Delaware corporation ("Sub") and wholly
owned subsidiary of Quanex Corporation, a Delaware corporation ("Quanex"), with
and into Temroc Metals, Inc., a Minnesota corporation ("Temroc"), pursuant to
which (1) except for any shares held by Dissenting Shareholders, each share of
Class A Common Stock, par value $.10 per share, of Temroc (the "Class A Shares")
that was outstanding immediately prior to the effective time of the Merger (the
"Effective Time") will be converted into the right to receive $291.99 in cash,
plus the applicable pro rata proportion of any purchase price adjustment under
Section 1.9(a) of the Agreement and Plan of Merger dated October 23, 2000 by and
among Quanex, Sub and Temroc (the "Merger Agreement") (the "Class A Merger
Consideration"), (2) except for any shares held by Dissenting Shareholders, each
share of Class B Common Stock, par value $.10 per share, of Temroc (the "Class B
Shares" and, together with the Class A Shares, the "Shares") that was
outstanding immediately prior to the Effective Time will be converted into the
right to receive $583.98 in cash, plus the applicable pro rata proportion of any
purchase price adjustment under Section 1.9(a) of the Merger Agreement (the
"Class B Merger Consideration"); for purposes of this agreement, the Class A
Merger Consideration and the Class B Merger Consideration shall collectively be
referred to as the "Merger Consideration") and (3) each issued and outstanding
shares of Class A Common Stock or Class B Common Stock that is held by
Dissenting Shareholders will be converted into the right to receive the
consideration as may be determined to be due such Dissenting Shareholders
pursuant to the laws of the State of Minnesota. You have agreed to act as paying
agent (the "Paying Agent") in connection with the Merger on the terms set forth
herein. The Effective Time is expected to be on _________, 2000. Until written
confirmation from Quanex or its counsel that the Effective Time has occurred,
the Merger Consideration shall be held by the Paying Agent for the exclusive
benefit of Quanex and Sub and shall not be distributed to any shareholder of
Temroc.

         1. Attached as Exhibit A hereto is a list of names, addresses and the
number of Class A Shares or Class B Shares owned by each of the holders of
Shares, except for Dissenting


   81
American Stock Transfer & Trust Company
__________, 2000
Page 2


Shareholders (the "Shareholder List"). Temroc shall update such list
periodically to reflect the ownership of Shares (except for shares held by
Dissenting Shareholders) immediately prior to the Effective Time. Promptly after
the Effective Time, Sub will deposit with the Paying Agent $_________ for the
Merger Consideration. Such funds will be held by the Paying Agent for the
purpose of paying to the holders of certificates formerly representing Shares
the Merger Consideration for each Share so converted. Pending payment by the
Paying Agent of any funds deposited with the Paying Agent pursuant to this
Paragraph 1, such funds will be invested in such short-term investments as
approved by Elmer Schumer, as the shareholder representative (the "Shareholder
Representative") and all proceeds of such investments as herein provided will be
paid to the holders of certificates formerly representing Shares in accordance
with the instructions of the Shareholder Representative. Any funds deposited
with the Paying Agent pursuant to this Paragraph 1, together with any interest
accrued thereon, that have not been used to make the payments described in this
Paragraph 1 within six months after the Effective Time will, at such time, be
paid to Temroc, and the Paying Agent will at such time deliver to Temroc the
Shareholder List. After such time, holders of the Shares will look only to
Temroc for payment.

         2. Upon the presentation and surrender to the Paying Agent of
certificates formerly representing Shares, together with a properly completed
and duly executed Letter of Transmittal, the Paying Agent will examine such
certificates and Letters of Transmittal to determine whether all signatures,
endorsements, stock powers, signature guarantees, evidence of authority and the
like required by the instructions to the Letter of Transmittal have been
provided. In the event such examination reveals any defect, the Paying Agent
will advise the person so surrendering the certificate or Letter of Transmittal
of such defects as soon as practicable. If there are no such defects noted, the
Paying Agent will promptly make payment to the registered owner (or such other
person who by accompanying documentation meeting normal transfer requirements,
including payment of any applicable transfer taxes, shall become the registered
owner) as set forth in Paragraph 1 hereof from the funds deposited with the
Paying Agent for such purpose pursuant to Paragraph 1 hereof.

         3. All certificates formerly representing Shares surrendered to the
Paying Agent with respect to which the Paying Agent has made payment as
contemplated herein will be canceled.

         4. The Paying Agent will take all such actions as may from time to time
be required by the Shareholder Representative, Quanex or Temroc to furnish
copies of the Letter of Transmittal and other documents relating to the Merger
in the possession of the Paying Agent to all persons requesting the same. Quanex
and Temroc will provide to the Paying Agent copies of such documents in such
quantities as the Paying Agent may reasonably request.

         5. The Paying Agent will comply with all of the requirements of the
Internal Revenue Code of 1986, as amended, and the Treasury Regulations
promulgated thereunder with respect to obtaining or retaining documents required
to be so obtained or retained by the Paying Agent with respect to payments,
including without limitation the obtaining and retaining of Substitute


   82
American Stock Transfer & Trust Company

Page 3

Forms W-9. On or before January 31, 2001, the Paying Agent will prepare and mail
to each holder of the Shares, other than holders who demonstrate their status as
nonresident aliens in accordance with the United States Treasury Regulations, a
Form 1099-B reporting any cash payments in accordance with the United States
Treasury Regulations. The Paying Agent will also prepare and file copies of such
Forms 1099-B by magnetic tape with the Internal Revenue Service in accordance
with United States Treasury Regulations. If the Paying Agent has not received
notice from the surrendering holder of the Shares of that holder's certified
Taxpayer Identification Number, the Paying Agent will deduct and withhold backup
withholding tax from any cash payment pursuant to Internal Revenue Code
regulations. Should any issue arise regarding federal income tax reporting or
withholding, the Paying Agent will take such action as Quanex or Temroc
instructs the Paying Agent in writing.

         6. The Paying Agent will furnish to Quanex and Temroc periodic reports
(on a weekly basis until 60 days after the Effective Time and thereafter on a
monthly basis by the 10th day of each month) showing the total number of Shares
surrendered and funds distributed. The Paying Agent will also furnish such other
information concerning its actions as Quanex or Temroc may reasonably request.

         7. The Paying Agent:

                  (a)      will have no obligations to make payments as set
                           forth in Paragraph 2 unless the funds therefor have
                           been deposited as set forth in Paragraph 1 hereof;

                  (b)      will have no duties or obligations other than those
                           specifically set forth herein, or as may subsequently
                           be agreed to by the Paying Agent, Quanex and Temroc;

                  (c)      may rely on and will be protected in acting upon any
                           certificate formerly representing Shares, instrument,
                           opinion, notice, letter, telegram or other document
                           delivered to the Paying Agent to be genuine and to
                           have been signed by the proper party or parties;

                  (d)      may rely on and will be protected in acting upon the
                           written or oral instructions, with respect to any
                           matter relating to its actions as the Paying Agent
                           specifically covered by this Agreement, of Quanex,
                           Temroc or their authorized representatives; and

                  (e)      may consult with counsel satisfactory to the Paying
                           Agent (including counsel for Quanex and Temroc) and
                           the advice or opinion of such counsel will be full
                           and complete authorization and protection in



   83
American Stock Transfer & Trust Company

Page 4
                           respect of any action taken or omitted to be taken by
                           the Paying Agent hereunder in good faith and in
                           accordance with such advice or opinion of such
                           counsel.

         8. For services rendered hereunder, __________ will pay to the Paying
Agent a fee of $____ plus any out-of-pocket expenses incurred by Paying Agent.
The Paying Agent will not be entitled to any additional compensation for its
services hereunder.

         9. Quanex and Temroc will jointly and severally indemnify and hold the
Paying Agent harmless against any costs, expenses, losses or damages that, in
the absence of negligence, misconduct or bad faith on the Paying Agent's part,
may be paid or incurred by the Paying Agent as a result of the performance of
its duties hereunder in accordance with the terms hereof. In no event will
Quanex or Temroc be liable under such indemnity with respect to any claim
asserted against the Paying Agent unless Quanex or Temroc shall have been
notified by the Paying Agent in writing of the assertion of such claim against
it after it receives notice of such claim from the person asserting the same.
Quanex and Temroc will be entitled to participate in the defense and, if it so
elects, to assume the defense of any suit or action brought to enforce any such
claim. In the event that it elects to assume the defense of any such suit or
action, Quanex and Temroc may select counsel of its own choosing for such
purpose and thereafter will not be liable for the fees or expenses of any
additional counsel retained by the Paying Agent. Notwithstanding the foregoing,
neither Quanex nor Temroc will have any obligation to indemnify the Paying Agent
with respect to any claim, suit or action that is compromised or settled by the
Paying Agent without Quanex's and Temroc's prior written consent.

         10. This agreement will be construed and enforced in accordance with
the substantive laws of the State of Minnesota without regard to the principles
of conflict of laws thereof.

         11. The instructions to the Paying Agent contained herein may at any
time or from time to time be modified or supplemented by further reasonable
written instructions delivered to the Paying Agent by Quanex or Temroc.

         12. The Paying Agent will supply a standard Letter of Transmittal
relating to holders of the Shares, a copy of which is attached hereto as Exhibit
A. Any inconsistency between the agreement, on the one hand, and the Letter of
Transmittal, on the other hand, will be resolved in favor of the latter.

         13. Capitalized terms used herein and not defined herein have the
meanings set forth in the Merger Agreement. A copy of the Merger Agreement is
attached to this letter as Exhibit B.

                                    EXHIBIT B
   87

                                                             Exhibit F to
                                                    Agreement and Plan of Merger

                           OPINION OF TEMROC'S COUNSEL

         1. Temroc is a corporation duly organized, validly existing and in good
standing under the laws of the State of Minnesota and has the corporate power
and authority to own, operate and lease its properties and carry on its business
in all material respects as now owned, operated, leased or conducted. Temroc is
duly qualified to conduct its business and is in good standing in each
jurisdiction in which the failure to be so qualified would have a material
adverse effect on Temroc's business.

         2. Temroc has all requisite corporate power and authority to enter
into, deliver and perform the Agreement and each agreement that is an exhibit to
the Agreement and to which Temroc is a party and to consummate the transactions
described in the Agreement. The Agreement has been duly executed and delivered
by Temroc pursuant to all necessary corporate action.

         3. The authorized capital stock of the Company consists of 100,000
shares of Class A Stock, $.10 par value, and 60,000 shares of Class B Stock,
$.10 par value, and based solely on our review of Temroc's minute book and stock
ledger there are 56,948 shares of Class A Stock and 3,670 shares of Class B
Stock which are issued and outstanding. Based solely on our review of Temroc's
minute book and stock ledger, each issued and outstanding share of Temroc's
Class A Stock and Class B Stock is duly authorized, validly issued, fully paid
and nonassessable and, to our knowledge, has not been issued and is not owned or
held, in violation of any preemptive right of shareholders. Based solely on our
review of Temroc's minute book and stock ledger, all issued and outstanding
shares of Temroc's Class A Stock and Class B Stock are owned of record by the
persons named on Exhibit A attached hereto.

         4. Neither the execution and delivery by Temroc of the Agreement, the
consummation of the transactions described in the Agreement by Temroc nor
compliance by Temroc with any other provisions of the Agreement will conflict
with, result in a breach of or constitute a default under (a) Temroc's Articles
of Incorporation or Bylaws, (b) any contracts, commitments or agreements listed
in a schedule to the Agreement or (c) any law, statue, ordinance, regulation or,
to our knowledge, court or administrative order by which Temroc is subject or
bound.

         5. Except as specifically set forth in the Agreement, to our knowledge,
Temroc is not required to submit any notice, report or other filing with any
governmental or regulatory authority or instrumentality in connection with the
execution, delivery or performance of the Agreement by Temroc and the
consummation of the transactions described in the Agreement.

         6. The Agreement is the legal, valid and binding obligation of Temroc;
and, except as may be limited by principles of equity or bankruptcy, insolvency,
reorganization, moratorium or other similar laws or judicial decision relating
to or affecting the enforcement of creditors' rights, is enforceable against
Temroc in accordance with its terms.



                                       1
   88



         7. Assuming no shareholder of Temroc duly exercises such shareholders'
rights of dissent pursuant to Section 302A.471 of the Minnesota Business
Corporation Act or makes any claim of fraudulent activity with respect to the
Merger, no shareholder will be entitled to the payment of any amounts in
connection with shares of Temroc stock with respect to the Merger, other than he
consideration described in the Agreement and, if applicable, the Escrow
Agreement.

                                                    Agreement and Plan of Merger


                           OPINION OF QUANEX'S COUNSEL

         (a) Each of Quanex and Quanex Subsidiary is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Delaware.

         (b) Each of Quanex and Quanex Subsidiary has all requisite corporate
power and authority to enter into, deliver and perform the Agreement and each
agreement that is an exhibit to the Agreement and to which Quanex or Quanex
Subsidiary is a party (excluding the Noncompetition Agreement) and to consummate
the transactions described in the Agreement. The Agreement has been duly
executed and delivered by Quanex and Quanex Subsidiary pursuant to all necessary
corporate action.

         (c) Neither the execution and delivery by Quanex or Quanex Subsidiary
of the Agreement, the consummation of the transactions described in the
Agreement by Quanex or Quanex Subsidiary nor compliance by Quanex or Quanex
Subsidiary with any of the provisions of the Agreement will conflict with,
result in a breach of or constitute a default under (a) the certificate of
incorporation or bylaws of Quanex or Quanex Subsidiary, (b) any contracts,
commitments or agreements listed as an exhibit to Quanex's Annual Report on Form
10-K for the year ended October 31, 1999, to which Quanex or Quanex Subsidiary
is a party or by which the assets of Quanex or Quanex Subsidiary are bound, or
(c) any law, statute, ordinance, regulation or, to our knowledge, court or
administrative order by which Quanex or Quanex Subsidiary is subject or bound.

         (d) Except as specifically set forth in the Agreement, to our
knowledge, neither Quanex nor Quanex Subsidiary is required to submit any
notice, report or other filing with any governmental or regulatory authority or
instrumentality in connection with the execution, delivery or performance of the
Agreement by Quanex and Quanex Subsidiary and the consummation of the
transactions described in the Agreement.

         (e) The Agreement is the legal, valid and binding obligation of Quanex
and Quanex Subsidiary, as applicable; and except as may be limited by principles
of equity or bankruptcy, insolvency, reorganization, moratorium or other similar
laws or judicial decisions relating to or affecting the enforcement of
creditors' rights, is enforceable against Quanex and Quanex Subsidiary in
accordance with its terms.

                                                    Agreement and Plan of Merger

   92

purchased by a customer listed on Exhibit B. Schumer and Crown agree that this
covenant is reasonable with respect to its duration, geographical area, and
scope. Schumer and Crown agree that the restrictions of this Section 3(b) shall

employees of Quanex or any of its subsidiaries other than Temroc or an Aluminum
Extrusion and Fabrication Subsidiary, except insofar as any such statement is
accurate, expresses ascertainable facts and does not express opinion or
speculation, and is necessary to the conduct of the business of Schumer or Crown
or (ii) is reasonably likely to have a material adverse effect on the ability of
Temroc or any Aluminum Extrusion and Fabrication Subsidiary to engage in any
business acquisition, except insofar as any such statement is accurate,
expresses ascertainable facts and does not express opinion or speculation, and
is necessary to the conduct of the business of Schumer or Crown.

         (f) Schumer shall, for a period of two years after the Closing, advise

4.       ADDITIONAL CONSIDERATION

($200,000), at Closing.

5.       ADDITIONAL AGREEMENTS

         (a) Quanex and Temroc agree that Schumer's ownership of Aacron and
Norfab and the activities of Aacron and Norfab shall not constitute a breach of
this Agreement with respect to the lines of business in which Aacron and Norfab
are currently engaged.

         (b) For a period of two years after the Closing, neither Quanex nor
Temroc shall make any statements, oral or written, that could negatively affect
Aacron or Norfab or any of their shareholders, directors, officers, employees or
agents except insofar as any such statement is accurate, expresses ascertainable
facts and does not express opinion or speculation, and is necessary to the
conduct of the business of Quanex and Temroc.

6.       REMEDIES

remedies:

         (a) monetary damages from Schumer and Crown, severally and not jointly;
and

         (b) In addition to its right to damages and any other rights it may
have, injunctive or other equitable relief to restrain any breach or threatened
breach or otherwise to specifically enforce the provisions of Section 4 of this
Agreement, it being agreed that money damages alone would be inadequate to
compensate Quanex and Temroc and would be an inadequate remedy for such breach.

         The rights and remedies of the parties to this Agreement shall be
cumulative and not alternative.

6.       SUCCESSORS AND ASSIGNS

         This Agreement will be binding on Quanex, Temroc, Schumer and Crown and
will inure to the benefit of Quanex, Temroc and their respective affiliates,
successors and assigns, and Schumer and his assigns, heirs and legal
representatives.

7.       WAIVER

         No failure or delay by any party in exercising any right, power or
privilege under this Agreement will operate as a waiver of any right, power or
privilege, and no single or partial exercise of any right, power or privilege
under this Agreement will preclude any other or further exercise of any right,
power or privilege or the exercise of any other right, power, or privilege. To
the maximum extent permitted by applicable law, (a) no claim or right arising
out of this Agreement can be discharged by one party, in whole or in part, by a
waiver or renunciation of the


                                       4
   94


claim or right unless in writing signed by the other party; (b) no waiver that
may be given by a party will be applicable except in the specific instance for
which it is given; and (c) no notice to or demand by a party to this Agreement
will be deemed to be a waiver of any obligation of that party to take further
action without notice or demand.

8.       GOVERNING LAW

         This Agreement will be governed by the internal laws of the State of
Minnesota without regard to conflicts of laws principles of any jurisdiction.

9.       SEVERABILITY

         Whenever possible each provision and term of this Agreement will be
interpreted in a manner to be effective and valid but if any provision or term
of this Agreement is held to be prohibited or invalid, then the provision or
term will be ineffective only to the extent of the applicable prohibition or
invalidity, without invalidating or affecting the remainder of the provision or
term or the remaining provisions or terms of this Agreement. Upon a
determination that any provision or term of this Agreement is prohibited or
invalid, the parties to this Agreement shall negotiate in good faith to modify
this Agreement to effect the original intent of the parties as closely as
possible in an acceptable manner, to the end that the transactions contemplated
by this Agreement are fulfilled to the extent possible. If any of the covenants
set forth in Section 3 are held to be unreasonable, arbitrary or against public
policy, it is the intention of the parties that the applicable covenants shall
not be terminated but shall be deemed amended to the extent required to render
them valid and enforceable.

10.      COUNTERPARTS

         This Agreement may be executed in one or more counterparts, each of
which shall be deemed to be an original copy of this Agreement and all of which,
when taken together, shall be deemed to constitute one and the same agreement.

11.      SECTION HEADINGS, CONSTRUCTION

         The headings of sections in this Agreement are provided for convenience
only and shall not affect its construction or interpretation. All references to
"Section" or "Sections" refer to the corresponding Section or Sections of this
Agreement unless otherwise specified. All words used in this Agreement shall be
construed to be of such gender or number as the circumstances require. Unless
otherwise expressly provided, the word "including" does not limit the preceding
words or terms.

12.      NOTICES

Agreement shall be in writing and shall be deemed to have been duly given when
(a) delivered by hand (with written confirmation of receipt), (b) sent by

addressee, if sent by a nationally recognized overnight delivery service
