ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

         Acquisition of HouTex Metals Company, Inc.

         On January 7, 1997 (the "Effective Date"), the Registrant, Metal
Management, Inc. (the "Company" or the "Registrant"), acquired all of the assets
of HouTex Metals Company, Inc., a Texas corporation ("HouTex") by means of a
reverse triangular merger in which the Company's wholly owned subsidiary, MTLM
Merger, Inc., a Texas corporation ("Sub"), was merged with and into HouTex, with
HouTex remaining as the surviving corporation, pursuant to a Merger Agreement
dated as of December 10, 1996, as amended by a First Amendment to Merger
Agreement dated December 10, 1996 (collectively the "Merger Agreement") among
the Company, Sub, HouTex, and the beneficial owners of HouTex's Common Stock
(the "Acquisition"). HouTex is a Houston, Texas-based scrap metal dealer. In
the Acquisition, the purchase price paid to the former shareholders of HouTex
consisted of an aggregate of (i) 475,000 shares of Common Stock of the Company,
(ii) warrants to purchase an aggregate of an additional 250,000 shares of Common
Stock of the Company, (iii) promissory notes for an aggregate of $1,655,268 due
on April 30, 1997, payable to Mike Melnik and Zalman Melnik (the "Melnik
Notes"), (iv) a promissory note for $5,000,000 due on June 30, 1997, payable to
Clend Investment Holdings, Ltd. ("Clend"), a British Virgin Islands corporation
indirectly controlled by Mike Melnik and Zalman Melnik (the "Clend Note"), and
(v) $750,000 in cash. Under the terms of the Acquisition, former HouTex
shareholder Clend, as holder of the Clend Note, also was granted the conditional
right to receive warrants for up to an additional 250,000 shares of Common Stock
of the Registrant if the Clend Note is not paid in full prior to its maturity
date. The holder of the Clend Note also has the option prior to April 30, 1997,
to convert up to $1 million of the remaining principal balance of the Clend Note
into Common Stock of the Registrant at a price per share equal to 75% of the
average closing price of the Registrant's Common Stock over the five trading
days immediately preceding the exercise of the option. Under certain conditions,
the holder of the Clend Note also has the option to convert prior to April 30,
1997, up to an additional $1 million of the remaining principal balance of the
Clend Note into shares of Common Stock of the Registrant at a price per share of
either $5.00 or $5.48, depending upon whether the average closing price of the
Registrant's stock is either more or less than $7.25 at the time the option is
exercised. At the same time as the Melnik Notes are due, on April 30, 1997, in
an aggregate amount of $1,655,268, a note in the amount of $405,268 is due to
HouTex from the Melniks in payment for certain HouTex assets that were
transferred to the Melniks.  The cash payments by the Registrant were paid out
of general working capital of the Registrant. The amount of consideration paid
by the Registrant in the Acquisition was determined in arm's-length negotiations
with the shareholders of HouTex. The Registrant also entered into a long-term
lease (the "Lease"), with an option to purchase, with respect to approximately
46 acres of real property and improvements in Houston, Texas, on which HouTex's
headquarters are located. This Lease is between the Company and an affiliate of
the former shareholders of HouTex that owns the real estate and improvements.
The purchase option feature of the Lease provides for fixed periods of time
during the term of the Lease in which the Registrant can purchase the property
for $4 million. The Lease also designates periods during the term of the Lease
in which the owner of the property can require the Registrant to purchase the
property for $4 million.  The earliest that either the Registrant or the owner
of the property may cause either the sale or the purchase of the property,
respectively, is during the 54th month of the Lease term.  The Registrant
intends to continue to utilize the leased premises as headquarters for HouTex's
scrap metal operations and to continue to utilize the assets of HouTex for scrap
metal recycling.

         The Melnik Notes and the Clend Note are secured by 100% of the capital
stock of HouTex, which was issued to the Registrant in connection with the
closing of the Acquisition. The Registrant is obligated to use its reasonable
best efforts to obtain replacement financing adequate to retire the Melnik Notes
and the Clend Note prior to their maturity dates. If the Registrant obtains
<PAGE>   3
such financing prior to April 30, 1997, the Registrant will be required under
the Merger Agreement to pay the Melnik Notes and the Clend Note in full within
five business days after receipt of the proceeds of such financing. The Merger
Agreement further provides that, if the Registrant uses its reasonable best
efforts to obtain replacement financing but has not done so before April 30,
1997, the obligations reflected by the Notes and the stock pledge and security
agreements entered into by the Registrant shall become non-recourse, and the
sole remedy available to the holders of the Melnik Notes and the Clend Note
shall be for the holders to exercise their rights under the stock pledge and
security agreements and foreclose on the shares of HouTex common stock issued to
the Registrant at the closing.

         Prior to the closing of the Acquisition, the Registrant, the
Registrant's affiliates, directors, officers, and associates of such directors
and officers had no material relationship with HouTex or any of its
shareholders, including Mike Melnik, Zalman Melnik or Clend. At the closing of
the Acquisition, Mike Melnik was elected to the Board of Directors of the
Registrant and Mike Melnik and Zalman Melnik signed five-year employment
agreements with the Registrant to serve as Chief Executive Officer and Chief
Operating Officer, respectively, of HouTex. Messrs. Mike Melnik and Zalman
Melnik were also elected by the Registrant following the closing of the
Acquisition to serve on the Board of Directors of HouTex.

         The Registrant has agreed to utilize as much as $4.5 million
of a $10 million short-term financing facility obtained through LaSalle National
Bank, Chicago, Illinois, ("LaSalle National") to refinance the line of credit
financing for HouTex and to provide additional working capital for HouTex. 
Approximately $3.5 million of this $4.5 million total is structured as a 
direct line of credit from LaSalle National to HouTex, and the remaining $1.0 
million of the $4.5 million total is structured as an unsecured line of 
credit from the Company to HouTex. (See Item 5. Other Events.)

         The Acquisition is intended to be treated as a purchase for financial
accounting purposes.

ITEM 5.  OTHER EVENTS

         On January 7, 1997, the Company and HouTex obtained a $10 million
short-term financing facility from LaSalle National. The credit facility
consists of a $6.5 million term loan to the Company (the "Company Loan") at an
interest rate of LIBOR plus 1.75%, and a revolving credit facility of $3.5
million to HouTex (the "HouTex Loan") at an interest rate of the prime rate plus
1%. Both loans are due June 30, 1997, but they may be extended until September
30, 1997, for a fee of $25,000. The HouTex Loan was secured by a first lien on
the assets of HouTex, as well as personal guaranties by certain officers and
directors of the Company. The Company Loan was unsecured, except for personal
guaranties from certain officers and directors of the Company. The officers and
directors guaranteeing the loans to the Company and HouTex have received 
warrants to purchase an aggregate of 500,000 shares of Common Stock of the 
Company for a price of $4.00 per share in consideration for making such 
guaranties. In connection with the Company Loan, the Company made available to
HouTex an additional $1 million pursuant to a Revolving Credit Note due 
contemporaneously with the other loans at an interest rate of the prime rate 
plus 1%, and subordinated such loan to the HouTex Loan.

The Share Consideration, the Warrants, the Cash Consideration, the Melnik Notes
and the Clend Note, as adjusted in accordance with this Agreement, shall be
collectively referred to as the "Merger Consideration".

         1.4      POST CLOSING ADJUSTMENT TO MERGER CONSIDERATION.

                  (a) Within 30 days after the Closing Date, MTLM will prepare
         and deliver to the HouTex Shareholders a draft balance sheet (the
         "Closing Date Balance Sheet") for HouTex as of the opening of business
         on the Closing Date. MTLM will prepare the Draft Closing Date Balance
         Sheet in accordance with GAAP. If the HouTex Shareholders have any
         objections to the Draft Closing Date Balance Sheet, they will deliver a
         detailed written statement describing their objections to MTLM within
         15 days after receiving the Draft Closing Date Balance Sheet. MTLM and
         the HouTex Shareholders will use reasonable efforts to resolve any such
         objections themselves. However, if MTLM and the HouTex Shareholders do
         not obtain a final resolution within 10 days after MTLM has received
         the written statement of objections from the HouTex Shareholders, MTLM
         and the HouTex Shareholders will select an accounting firm, mutually
         acceptable to them to resolve any remaining objections. If MTLM and the
         HouTex Shareholders are unable to agree on the choice of an accounting
         firm, they will select a "Big Six" accounting firm by lot (after
         excluding their respective outside accounting firms). The determination
         of any accounting firm so selected will be set forth in writing and
         will be conclusive and binding upon the parties. MTLM will revise the
         Draft Closing Date Balance Sheet as appropriate to reflect the
         resolution of any objections thereto pursuant to this Section 1.4. The
         "Closing Date Balance Sheet" shall mean the Draft Closing Date Balance
         Sheet together with any revisions thereto pursuant to this Section 1.4.
         In the event the parties submit any unresolved objections to an
         accounting firm for resolution as provided in this Section 1.4, MTLM
         and the HouTex Shareholders will share equally the responsibility for
         the fees and expenses of the accounting firm selected. MTLM will make
         the work papers


                                      - 3 -

<PAGE>   11
         and back-up materials used in preparing the Draft Closing Date Balance
         Sheet, and the books and records of HouTex, available to the HouTex
         Shareholders and their accountants and representatives at reasonable
         times upon reasonable notice at any time during (i) the preparation of
         the Draft Closing Date Balance Sheet by MTLM; (ii) the review by the
         HouTex Shareholders of the Draft Closing Date Balance Sheet, and (iii)
         the resolution by the parties of any objections thereto.

                  (b) Pursuant to Section 5.15 hereof, the HouTex Shareholders
         have covenanted that HouTex shall have an after tax net income
         determined in accordance with Section 5.15 for the twelve month period
         ending on the Minimum Net Income Determination Date (as defined in
         Section 5.15) of not less than the Minimum Net Income (as defined in
         Section 5.15). In the event the actual after tax net income of HouTex
         determined in accordance with Section 5.15 for the twelve month period
         ending on the Minimum Net Income Determination Date is less than the
         Minimum Net Income, the HouTex Shareholders will pay MTLM an amount
         equal to such deficiency (plus interest thereon at the Applicable Rate)
         by the wire transfer or delivery of other immediately available funds
         within three (3) business days after notification by MTLM in writing of
         the actual after tax net income of HouTex determined in accordance with
         Section 5.15 for the twelve (12) month period ending on the Minimum Net
         Income Determination Date. MTLM shall have the option of recouping all
         or any part of any amount the HouTex Shareholders owe MTLM pursuant to
         this 1.4 (b) by notifying the HouTex Shareholders that MTLM is reducing
         (in accordance with Article VIII) pro rata the Held Back Shares or
         setting off such amount owed by the HouTex Shareholders against: (a)
         amounts due to Mike and Sol Melnik or any entity which they form to
         hold title to the Japhet Property (as such property is defined in
         Section 5.14 hereof), or their or its respective successors in interest
         under the Lease (such person, persons or entity being hereafter
         referred to as the "Lessor"), or (b) amounts due under the Melnik
         Notes, or (c) amounts due under the Clend Note. Any dispute arising
         between MTLM and the HouTex Shareholders with regard to the accuracy of
         MTLM's determination of HouTex's actual net income determined in
         accordance with Section 5.15 hereof for the period ending on the
         Minimum Net Income Determination Date shall be resolved in the same
         manner as a dispute arising under Section 1.4 (a) hereof.

         1.5      DETERMINATION OF EXERCISE PRICE FOR WARRANTS. The exercise 
price per share for the Five Year Warrants and Limited Warrants shall be fixed
at Closing in an amount equal to the average of the closing bid and asked prices
(the "Closing Stock Price") of MTLM's common stock on the Nasdaq National Market
System on the last business day preceding the Closing Date.

                              ADDITIONAL AGREEMENTS

         5.1 FURTHER ASSURANCES. Each party shall execute and deliver such
additional instruments and other documents and shall take such further actions
as may be necessary or appropriate to effectuate, carry out and comply with all
of the terms of this Agreement and the transactions contemplated hereby.


                                     - 32 -
<PAGE>   40
         5.2 COMPLIANCE WITH COVENANTS. The HouTex Shareholders shall cause
HouTex to comply with all of the respective covenants of HouTex under this
Agreement.

         5.3 COOPERATION. Each of the parties agrees to cooperate with the other
in the preparation and filing of all forms, notifications, reports and
information, if any, required or reasonably deemed advisable pursuant to any
law, rule or regulation or the rules of any exchange on which the MTLM Common
Stock is listed (the Nasdaq Stock Market) in connection with the transactions
contemplated by this Agreement and to use their respective best efforts to agree
jointly on a method to overcome any objections by any Governmental Authority to
any such transactions.

         5.4 ACCESS TO INFORMATION. From the date hereof to the Effective Time,
HouTex and HouTex Shareholders shall (and shall cause the directors, officers,
employees, auditors, counsel and agents of HouTex to) afford MTLM and MTLM's
officers, employees, auditors, counsel and agents reasonable access at all
reasonable times to its properties, offices, and other facilities, to its
officers and employees and to all books and records, and shall furnish such
persons with all financial, operating and other data and information as may be
requested. No information provided to or obtained by MTLM shall affect any
representation or warranty in this Agreement. MTLM agrees to provide Mike Melnik
and Sol Melnik access to senior executive officers and directors of both MTLM
and any of its operating subsidiaries, as well as the right to investigate MTLM,
its business and assets.

         5.5 NOTIFICATION OF CERTAIN MATTERS. The HouTex Shareholders shall give
prompt notice to MTLM of the occurrence or non-occurrence of any event which
would likely cause any representation or warranty contained herein to be untrue
or inaccurate, or any covenant, condition, or agreement contained herein not to
be complied with or satisfied. MTLM will use its reasonable best efforts to
advise HouTex of any breach of any of HouTex's representations, warranties,
covenants or agreements contained herein which become known to MTLM.

         5.6 TAX TREATMENT. MTLM, HouTex, and the HouTex Shareholders
acknowledge that the Merger does not qualify as a tax free reorganization under
the provisions of Section 368(a) of the Code and is therefore taxable. All
parties hereto agree to fully and completely comply with the reporting
requirements of the Internal Revenue Service.

         5.7 CONFIDENTIALITY; PUBLICITY. Except as may be required by law or as
otherwise permitted or expressly contemplated herein, no party hereto or their
respective Affiliates, employees, agents and representatives shall disclose to
any third party this Agreement or the subject matter or terms hereof without the
prior consent of the other parties hereto. No press release or other public
announcement related to this Agreement or the transactions contemplated hereby
shall be issued by any party hereto without the prior approval of the


                                     - 33 -
<PAGE>   41
other parties, except that MTLM may make such public disclosure which it
believes in good faith to be required by law or by the terms of any listing
agreement with or requirements of a securities exchange (in which case MTLM will
consult with Mike or Sol Melnik prior to making such disclosure).

         5.8 NO OTHER DISCUSSIONS. HouTex, the HouTex Shareholders, and their
respective Affiliates, employees, agents and representatives will not (i)
initiate, encourage the initiation by others of discussions or negotiations with
third parties or respond to solicitations by third persons relating to any
merger, sale or other disposition of any substantial part of the assets,
business or properties of HouTex (whether by merger, consolidation, sale of
stock or otherwise) or (ii) enter into any agreement or commitment (whether or
not binding) with respect to any of the foregoing transactions. The HouTex
Shareholders will immediately notify MTLM if any third party attempts to
initiate any solicitation, discussion or negotiation with respect to any of the
foregoing transactions.

         5.9 RESTRICTIVE COVENANTS. In order to assure that MTLM will realize
the benefits of this Agreement and in consideration of the transactions set
forth in this Agreement, Mike and Sol Melnik jointly and severally, each agree
with MTLM that they will not for a period of three years from the later of the
Effective Time or the date they cease to be an employee, officer or director of
the MTLM Companies:

              (a) directly or indirectly, alone or as a partner, joint venturer,
officer, director, employee, consultant, agent, independent contractor or
stockholder of any company or business, engage in any business activity in the
State of Texas which is directly or indirectly in competition with the business
conducted by HouTex at the Effective Time; provided, however, that, the
beneficial ownership of less than five percent (5%) of the shares of stock of
any corporation having a class of equity securities actively traded on a
national securities exchange or over-the-counter market shall not be deemed, in
and of itself, to violate the prohibitions of this Section;

              (b) directly or indirectly (i) induce any Person which is a
customer of HouTex at the Effective Time to patronize any business directly or
indirectly in competition with the business conducted by HouTex; (ii) canvass,
solicit or accept from any Person which is a customer of HouTex, any such
competitive business, or (iii) request or advise any Person which is a customer
of HouTex at the Effective Time to withdraw, curtail or cancel any such
customer's business with HouTex;

              (c) directly or indirectly employ, or knowingly permit any company
or business directly or indirectly controlled by him, to employ, any person who
was employed by HouTex at or within six months prior to the Effective Time, or
in any manner seek to induce any such Person to leave his or her employment;


                                     - 34 -
<PAGE>   42
              (d) directly or indirectly, at any time following the Effective
Time, in any way utilize, disclose, copy, reproduce or retain in his possession
any of HouTex's proprietary rights or records, including, but not limited to,
any of their customer lists.

Mike Melnik and Sol Melnik agree and acknowledge that the restrictions contained
in this Section 5.9 are reasonable in scope and duration and are necessary to
protect MTLM Companies after the Effective Time. If any provision of this
Section as applied to any party or to any circumstance is adjudged by a court to
be invalid or unenforceable, the same will in no way affect any other
circumstance or the validity or enforceability of this Agreement. If any such
provision, or any part thereof, is held to be unenforceable because of the
duration of such provision or the area covered thereby, the parties agree that
the court making such determination shall have the power to reduce the duration
and/or area of such provision, and/or to delete specific words or phrases, and
in its reduced form, such provision shall then be enforceable and shall be
enforced. The parties agree and acknowledge that the breach of this Section will
cause irreparable damage to the MTLM Companies and upon breach of any provision
of this Section, the MTLM Companies shall be entitled to injunctive relief,
specific performance or other equitable relief; provided, however, that, this
shall in no way limit any other remedies which the MTLM Companies may have
(including, without limitation, the right to seek monetary damages).

         5.10 ENVIRONMENTAL ASSESSMENT. MTLM shall be entitled to have conducted
prior to Closing an environmental assessment of the Owned Properties and Leased
Premises (hereinafter referred to as "Environmental Assessment"). The
Environmental Assessment may include, but not be limited to, a physical
examination of the Owned Property or Leased Premises, and any structures,
facilities, or equipment located thereon, soil samples, ground and surface water
samples, storage tank testing, review of pertinent records, documents, and
Licenses of HouTex. The HouTex Shareholders shall provide MTLM or its designated
agents or consultants with the access to such property which MTLM, its agents or
consultants require to conduct the Environmental Assessment. Notwithstanding any
other provision of this Agreement, the HouTex Shareholders agree that if the
results of the Environmental Assessment are not satisfactory to MTLM in its sole
discretion, then MTLM may elect not to close the transactions contemplated by
this Agreement.

Prior to the date hereof, MTLM retained ENVIRON Corporation, Emeryville,
California ("ENVIRON") to conduct a Phase I Environmental Audit of certain Owned
Property of HouTex located in Houston, Texas. A draft of ENVIRON's written
report dated September 13, 1996 has been furnished to the HouTex Shareholders
(the "ENVIRON Report"). The ENVIRON Report identifies certain environmental
issues concerning HouTex's Owned Property located at (i) 15 Japhet Street and 21
Japhet Street, Houston, Texas (the "Japhet Property"), (ii) 12000 Hirsch Road,
Houston, Texas (the "Hirsch Property"), and (iii) 215 Emile Street, Houston,
Texas (the


                                     - 35 -
<PAGE>   43
"Emile Property"). After consultation with their respective attorneys and
consultants, MTLM and the HouTex Shareholders agree that certain specified
conditions at the Japhet Property should be promptly remediated as set forth
below and that the HouTex Shareholders should indemnify the MTLM Companies under
Section 8.1(f) hereof (in lieu of the general indemnification provisions in
Section 8.1(a)-(e)) from any further liabilities or obligations arising from, or
related to the Hirsch Property or the Emile Property. Remedies available to the
MTLM Companies in the event of liabilities or obligations related to the Hirsch
Property or the Emile Property shall include the rights of setoff subject to the
terms and conditions described in Article 8 hereof. The specified conditions to
be promptly remediated at the Japhet Property, and the method of sharing the
costs of remediation shall be as follows:

                  (a) Scope of Prompt Japhet Property Remediation. The ENVIRON
         Report identifies on page five certain recommended remedial work
         concerning chemical use and storage on the Japhet Property. The HouTex
         Shareholders and MTLM agree that following the Closing MTLM will cause
         HouTex to develop and implement a Spill Prevention Control and
         Countermeasure (SPCC) Plan and to provide secondary containment for the
         diesel fuel and oily wastewater storage tanks, in order to comply with
         federal regulations. The cost estimated by ENVIRON to develop the SPCC
         Plan is $5,000 to $10,000 and the costs of providing secondary
         containment for the diesel fuel and oily wastewater storage tanks were
         estimated by ENVIRON to be in the range of $60,000 to $90,000. The
         parties agree that all of the work described above should be performed
         as promptly as practicable following Closing, such work being hereafter
         referred to as the "Agreed Remediation."

                  (b) Costs of Agreed Remediation. The actual costs of all
         Agreed Remediation shall be allocated and paid as follows:

<TABLE>
<CAPTION>
                  Party Bearing Expense              Amount
                  ---------------------              ------
                  <S>                                <C>    
                  HouTex                             first $75,000
                  HouTex Shareholders                next $75,000
                  HouTex                             all amounts over $150,000;
</TABLE>

         In the event the HouTex Shareholders fail to pay their allocable share
         of the actual costs of Agreed Remediation within ten (10) days
         following delivery of an invoice for such actual costs, MTLM is
         authorized to setoff the HouTex Shareholders' allocable share of such
         actual costs against the Held Back Shares or the payments owed by
         HouTex or MTLM under the Lease.

                  (c) Future Remediation Costs. All future costs of, and
         liabilities associated with, undertaking and completing the evaluation
         and remediation of contamination present on the Japhet Property as of
         the Closing Date, other than the costs of undertaking and


                                     - 36 -
<PAGE>   44
         completing the Agreed Remediation which shall be allocated and paid by
         HouTex and the HouTex Shareholders as described in clause (a) above,
         shall be borne by the HouTex Shareholders under and pursuant to the
         indemnification procedures specified in Article VIII hereof, regardless
         of whether or not such other contamination was referenced, discussed or
         otherwise identified in the Environmental Assessment or any other part
         of MTLM's due diligence investigation of HouTex. In any event, the
         ENVIRON Report and the other environmental due diligence investigations
         of HouTex by MTLM shall not affect any representation or warranty of
         the HouTex Shareholders under this Agreement.

         5.11 TRADING IN MTLM COMMON STOCK. Except as otherwise expressly
consented to by MTLM, from the date of this Agreement until the Effective Time,
neither HouTex nor the HouTex Shareholders (nor any Affiliates thereof) will
directly or indirectly purchase or sell (including short sales) any shares of
MTLM Common Stock in any transactions effected on the Nasdaq Stock Market or
otherwise.

         5.12 ELECTION OF NEW DIRECTOR. Immediately following the Closing, Mike
Melnik will be added to MTLM's Board of Directors in accordance with the terms
and conditions of a resolution of the MTLM Board of Directors adopted prior to
the Closing which elects Mike Melnik to the Board of MTLM, contingent only upon
(i) the Closing having occurred and (ii) Mike Melnik having agreed in writing
following the Closing to serve as a director of MTLM.

         5.13 EMPLOYMENT AGREEMENTS. MTLM and Mike Melnik agree that Mike Melnik
will sign, at Closing, an employment agreement in the form of Exhibit "C"
hereto. MTLM and Sol Melnik agree that Sol Melnik will sign, at Closing, an
employment agreement in the form of Exhibit "D" hereto. The parties agree that
the noncompetition covenants contained in the Employment Agreements for Mike and
Sol Melnik are an integral part of this Agreement.

         5.14 LEASE OF REAL PROPERTY. At the Closing, HouTex will enter into a
lease with an option to purchase (the "Lease") in the form attached hereto as
Exhibit "I" concerning the approximately forty-seven (47) acre tract of real
property (the "Japhet Property") located in Harris County, Texas which is
described in Exhibit "E" hereto with the Lessor (as defined in Section 1.4
hereof) who will be the record and beneficial owner of the Japhet Property on
the date of Closing. Mike and Sol Melnik acknowledge and agree that during the
period following Closing in which they serve as senior officers and/or directors
of HouTex, there will be potential conflicts of interest between their roles as
officers and directors of HouTex and their roles as controlling persons of the
Lessor under the Lease. Mike and Sol Melnik further acknowledge and agree that
no event of default under the Lease may be caused, directly or indirectly, by
the actions or failures to act, of Mike or Sol Melnik, while serving as officers
and/or directors of HouTex following the Closing. Also, none of the rights


                                     - 37 -
<PAGE>   45
granted to Mike and Sol Melnik, either directly or indirectly, as controlling
persons of the Lessor under the Lease are meant to relieve Mike and Sol Melnik
of the duties imposed upon officers and directors of corporations by the laws of
the State of Texas. In this regard, Mike and Sol Melnik shall not have the right
on behalf of HouTex to waive any default by Lessor under the Lease nor to agree
on behalf of HouTex to any modification of the Lease or its terms, without the
written consent of a majority of the disinterested members of the Board of
Directors of HouTex.

         5.15 POST CLOSING MINIMUM NET INCOME. The HouTex Shareholders hereby
covenant and agree with MTLM that HouTex shall have after tax net income of Nine
Hundred Thousand Dollars ($900,000), determined in accordance with GAAP as
adjusted in accordance with Exhibit "F" (the "Minimum Net Income") during the
period beginning on the first day of October, 1996 and ending on September 30,
1997 (the "Minimum Net Income Determination Date").

         5.16 HOUSTON COMPRESSED STEEL FINDERS FEE. In the event MTLM, or any of
its subsidiaries or affiliates merges with, or otherwise acquires all of the
stock or assets of Houston Compressed Steel within two years of the Closing
Date, MTLM shall pay a one time, aggregate lump sum finders fee of no more than
$600,000 and no less than $300,000 to Mike and Sol Melnik, jointly, and an
amount of up to $150,000 to Robert Stuart (in the event HouTex is legally
obligated to pay a finder's fee to Robert Stuart) on the date the stock or
assets of Houston Compressed Steel are acquired by MTLM.

         5.17 PRECLOSING AUDIT OF HOUTEX. MTLM agrees to retain Price Waterhouse
L.L.P. for the purposes of auditing HouTex's financial statements for the fiscal
year ending September 30, 1993, September 30, 1994 and September 30, 1995, as
well as for the period ending June 30, 1996. HouTex consents to cooperate fully
in connection with the planning, conduct and completion of the audits of HouTex
for such periods. HouTex agrees that it will provide all information, documents
and other materials requested by Price Waterhouse L.L.P. in connection with
these audits, and MTLM agrees to allow HouTex access to all work papers of Price
Waterhouse L.L.P. and access to a copy of the draft opinion of Price Waterhouse
together with all back-up materials which document the adjusting entries, if
any, proposed by Price Waterhouse. The Parties will negotiate in good faith any
disputes in connection with the issuance of the draft opinion.

         5.18 CORPORATE AUTHORITY. The MTLM Companies, HouTex and the HouTex
Shareholders agree to use their individual best efforts to obtain the
authorizations required for each to execute and deliver this Agreement and to
perform each of their respective obligations hereunder and to consummate the
transactions contemplated hereby.

         5.19 CERTIFICATION OF TAX STATUS. Each of the HouTex Shareholders shall
deliver to MTLM either: (i) a Certificate of Nonforeign Status under Treasury
Regulation Section


                                     - 38 -

1.1445-2(b)(1), or (ii) a Certificate meeting the requirements of Treasury
Regulation Sections 1.897-2(g) and 1.897-2(h)(2) that the HouTex shares do not
constitute a U.S. real property interest.

         5.20 NATIONSBANK FINANCING; RELEASE OF GUARANTORS. Mike Melnik and Sol
Melnik covenant and agree that prior to Closing they will use their individual
best efforts to cause NationsBank to consent to the Merger and agree that the
existing line of credit from NationsBank to HouTex (the "NationsBank Loan") will
remain in full force and effect at least through June 30, 1997 and that Mike and
Sol Melnik agree to remain as guarantors on the NationsBank Loan through no
later than June 30, 1997. MTLM covenants and agrees that it will pay off or
refinance the NationsBank Loan and obtain the release of Mike and Sol Melnik's
personal guarantees of the NationsBank Loan no later than June 30, 1997.

         5.21 EXTRANEOUS ASSETS. Mike Melnik and Sol Melnik covenant and agree
that prior to Closing they will purchase the Extraneous Assets described on
Exhibit "H". The purchase price for the Extraneous Assets shall consist of the

         8.1 AGREEMENT BY THE HOUTEX SHAREHOLDERS TO INDEMNIFY. The HouTex
Shareholders, jointly and severally, agree to indemnify and hold MTLM and HouTex
harmless from and against the aggregate of all Indemnifiable Damages (as defined
below).


                                     - 46 -
<PAGE>   54
              (a) For purposes of this Agreement, "Indemnifiable Damages" means,
without duplication, the aggregate of all expenses, losses, costs, deficiencies,
liabilities and damages (including, without limitation, related counsel and
paralegal fees and expenses) incurred or suffered by MTLM or HouTex, on a
pre-tax basis, to the extent (i) resulting from any breach of a representation
or warranty made by the HouTex Shareholders in or pursuant to this Agreement,
(ii) resulting from any breach of the covenants or agreements made by any HouTex
Shareholder in or pursuant to this Agreement, (iii) resulting from any breach by
Lessor under the Lease, or (iv) resulting from any inaccuracy in any certificate
delivered by any HouTex Shareholder pursuant to this Agreement.

              (b) Without limiting the generality of the foregoing, with respect
to the measurement of Indemnifiable Damages, MTLM and HouTex shall have the
right to be put in the same pre-tax financial position as each would have been
in had each of the representations and warranties of the HouTex Shareholders
hereunder been true and correct and had the covenants and agreements of the
HouTex Shareholders hereunder been performed in full.

              (c) Except as provided in paragraph 8.1(f) below, each of the
representations and warranties made by the HouTex Shareholders in this Agreement
or pursuant hereto shall survive for a period of fourteen (14) months after the
Effective Time, notwithstanding any investigation at any time made by or on
behalf of MTLM or HouTex and upon expiration of such fourteen (14) month period,
such representations and warranties shall expire except as follows: (i) the
representations and warranties of the HouTex Shareholders contained in Section
3.19, and to the extent relating to tax attributes or liabilities with respect
to Taxes of HouTex, shall expire at the time the period of limitations
(including any extensions thereof pursuant to the delivery of waivers of the
applicable period of limitations) expires for the assessment by the taxing
authority of additional Taxes with respect to which the representations and
warranties relate; (ii) the representations and warranties of the HouTex
Shareholders contained in Sections 3.13 and 3.16 shall expire at the time the
latest period of limitations expires for the enforcement by an applicable
Governmental Authority of any remedy with respect to which the particular
representations and warranties of the HouTex Shareholders relates and if there
is no such period of limitations, then the representations and warranties shall
continue indefinitely; and (iii) the representations and warranties of the
HouTex Shareholders contained in Sections 3.1, 3.2, 3.3, 3.4, and 3.5 shall not
expire, but shall continue indefinitely. No claim for the recovery of
Indemnifiable Damages may be asserted by MTLM and/or HouTex against the HouTex
Shareholders after such representations and warranties shall thus expire,
provided, however, that claims for Indemnifiable Damages first asserted within
the applicable period shall not thereafter be barred. Notwithstanding any
knowledge of facts determined or determinable by any party by investigation,
each party shall have the right to fully rely on the representations,
warranties, covenants and agreements of the other parties contained in this


                                     - 47 -
<PAGE>   55
Agreement or in any other documents or papers delivered in connection herewith.
Each representation, warranty, covenant and agreement of the parties contained
in this Agreement is independent of each other representation, warranty,
covenant and agreement. Anything to the contrary herein notwithstanding, all
representations and warranties of the HouTex Shareholders shall not survive a
"change in control" of MTLM which occurs at any time after the Closing. Solely
for purposes of this Section 8.1(c), a "change in control" shall be deemed to
have occurred at any point in time that neither T. Benjamin Jennings or Gerard
M. Jacobs serves as Chief Executive Officer of MTLM.

              (d) In the event that either MTLM or HouTex believe they are
entitled to a claim for any Indemnifiable Damages hereunder, MTLM and/or HouTex
shall promptly give written notice to the HouTex Shareholders of such claim and
the amount or the estimated amount of such claim, and the basis for such claim.
If the HouTex Shareholders do not pay the amount of the claim for Indemnifiable
Damages to MTLM or HouTex within ten (10) days, then MTLM may set off the amount
of such claim by selling some or all of the Held Back Shares and retaining the
net proceeds thereof as a set off against the claim in accordance with the
procedures, and subject to the HouTex Shareholders' right to contest such claim,
as set forth in Sections 8.3 and 8.4 below. Alternatively, MTLM may retain some
or all of the Held Back Shares as a direct set off against such claims in
accordance with the procedures, and subject to the HouTex Shareholders' right to
contest such claims, as set forth in sections 8.3 and 8.4 below. If the Held
Back Shares are insufficient to set off the claim (or have been delivered to the
HouTex Shareholders prior to the making or resolution of such claim), MTLM
and/or HouTex may take any action or exercise any remedy available to MTLM or
HouTex by appropriate legal proceedings to collect the Indemnifiable Damages,
including setting off the Indemnifiable Damages against either: (a) the Melnik
Notes, (b) the Clend Note, (c) rental or other payments due to Lessor from
HouTex (and guaranteed by MTLM) under the Lease, or (d) against the purchase
price to be paid to Lessor for the Premises by HouTex (payment of which is
guaranteed by MTLM) under the Lease.

              (e) Notwithstanding anything to the contrary in this Section 8.1,
except as set forth in 8.1(f) below, the HouTex Shareholders shall not be liable
to MTLM or HouTex with respect to any claim for Indemnifiable Damages unless all
Indemnifiable Damages incurred by MTLM and HouTex exceed an aggregate of
$50,000, in which case the HouTex Shareholders shall be liable for the full
amount of such Indemnifiable Damages in excess of $50,000; provided however, in
the event the Indemnifiable Damage arises from a breach of a representation or
warranty contained in Section 3.13 hereof relating to the Japhet Property (the
"Japhet Environmental Indemnifiable Damages"), the HouTex Shareholders shall not
be liable to MTLM or HouTex with respect to any claim for Japhet Environmental
Indemnifiable Damages unless all such Japhet Environmental Indemnifiable Damages
incurred by MTLM or HouTex exceed an aggregate of $75,000 in which case the
HouTex Shareholders shall be liable for the full amount of such Japhet
Environmental Indemnifiable Damages in excess of $75,000.

<PAGE>   56
              (f) Notwithstanding anything to the contrary in this Section 8.1,
the HouTex Shareholders shall be liable for all Indemnifiable Damages (including
engineering, consulting, and legal fees) incurred by MTLM and HouTex arising
from, or related in any way to, the Hirsch Property or the Emile Property. The
$50,000 and $75,000 monetary thresholds of liability for collection of
Indemnifiable Damages set forth in subparagraph 8.1(e) above shall not apply to
Indemnifiable Damages related to the Hirsch Property and the Emile Property.
Similarly, the survival periods for certain representations and warranties set
forth in subparagraph 8.1(c) above shall not apply to the representations and
warranties herein with regard to the Emile Property and the Hirsch Property; the
representations and warranties of the HouTex Shareholders herein shall survive
Closing and shall not expire as they relate to the Emile Property or the Hirsch
Property.

         8.2  AGREEMENT BY THE MTLM COMPANIES TO INDEMNIFY. MTLM agrees to
indemnify and hold the HouTex Shareholders harmless from and against the
aggregate of all HouTex Indemnifiable Damages (as defined below).

              (a) For purposes of this Agreement, "HouTex Indemnifiable Damages"
means, without duplication, the aggregate of all expenses, losses, costs,
deficiencies, liabilities and damages (including, without limitation, related
counsel and paralegal fees and expenses) incurred or suffered by the HouTex
Shareholders, on a pre-tax consolidated basis, to the extent (i) resulting from
any breach of a representation or warranty made by MTLM in or pursuant to this
Agreement, (ii) resulting from any breach of the covenants or agreements made by
MTLM in or pursuant to this Agreement, or (iii) resulting from any breach by
HouTex of the Lease; or (iv) resulting from any inaccuracy in any certificate
delivered by MTLM pursuant to this Agreement.

              (b) Without limiting the generality of the foregoing, with respect
to the measurement of HouTex Indemnifiable Damages, each HouTex Shareholder
shall have the right to be put in the same pre-tax consolidated financial
position as he, she or it would have been in had each of the representations and
warranties of MTLM hereunder been true and correct and had the covenants and
agreements of MTLM hereunder been performed in full.

              (c) Each of the representations and warranties made by MTLM in
this Agreement or pursuant hereto shall survive for a period of one year after
the Effective Time, notwithstanding any investigation at any time made by or on
behalf of the HouTex Shareholders, and upon expiration of such one year period,
such representations and warranties shall expire. No claim for the recovery of
HouTex Indemnifiable Damages may be asserted by the HouTex Shareholder against
MTLM after such representations and warranties shall thus expire, provided,
however, that claims for Indemnifiable Damages first asserted within the
applicable period shall not thereafter be barred. Notwithstanding any knowledge
of facts determined or determinable by any party by investigation, each party


                                     - 49 -
<PAGE>   57
shall have the right to fully rely on the representations, warranties, covenants
and agreements of the other parties contained in this Agreement or in any other
documents or papers delivered in connection herewith. Each representation,
warranty, covenant and agreement of the parties contained in this Agreement is
independent of each other representation, warranty, covenant and agreement.

              (d) In the event that the HouTex Shareholders believe they are
entitled to a claim for any Indemnifiable Damages hereunder, the HouTex
Shareholders shall promptly give written notice to MTLM of such claim and the
amount or the estimated amount of such claim, and the basis for such claim.

              (e) Notwithstanding anything to the contrary in this Section 8.2,
MTLM shall not be liable to the HouTex Shareholders with respect to any claim
for Indemnifiable Damages unless all Indemnifiable Damages incurred by the
HouTex Shareholders exceed an aggregate of $50,000, in which case the MTLM
Companies shall be liable for the full amount of such Indemnifiable Damages.

         8.3  CONDITIONS OF INDEMNIFICATION. The obligations and liabilities of
the HouTex Shareholders, MTLM and HouTex hereunder with respect to their
respective indemnities pursuant to this Article VIII resulting from any claim or
other assertion of liabilities by third parties (hereinafter called collectively
"Claims"), shall be subject to the following terms and conditions:

              (a) the party seeking indemnification (the "Indemnified Party")
must give the other party or parties, as the case may be (the "Indemnifying
Party"), notice of any such Claim promptly after the Indemnified Party receives
notice thereof;

              (b) the Indemnifying Party shall have the right to undertake, by
counsel or other representatives of it own choosing, the defense of such claim;

              (c) in the event that the Indemnifying Party shall elect not to
undertake such defense, or within a reasonable time after notice of any such
Claim from the Indemnified Party shall fail to defend, the Indemnified Party
(upon further written notice to the Indemnifying Party) shall have the right to
undertake the defense, compromise or settlement of such Claim, by counsel or
other representatives of its own choosing, on behalf of and for the account and
risk of the Indemnifying Party (subject to the right of the Indemnifying Party
to assume defense of such Claim at any time prior to settlement, compromise or
final determination thereof);

              (d) Anything in this Section 8.3 to the contrary notwithstanding,
(A) the Indemnified Party shall have the right, at its own cost and expense, to
have its own counsel


                                     - 50 -
<PAGE>   58
to protect its own interests and participate in the defense, compromise or
settlement of the Claim, (B) the Indemnifying Party shall not, without the
Indemnified Party's written consent, settle or compromise any Claim or consent
to entry of any judgement which does not include as an unconditional term
thereof the giving by the claimant or the plaintiff to the Indemnified Party of
a release from all liability in respect of such Claim, and (C) the Indemnified
Party, by counsel or other representatives of its own choosing and at its sole
cost and expense, shall have the right to consult with the Indemnifying Party
and its counsel or other representatives concerning such Claim, and the
Indemnifying Party and the Indemnified Party and their respective counsel shall
cooperate with respect to such Claim.

         8.4      HELD BACK SHARES AND RIGHTS OF SETOFF TO SECURE THE HOUTEX
SHAREHOLDERS' INDEMNIFICATION OBLIGATION. As security for the agreement by the
HouTex Shareholders to indemnify and hold MTLM and HouTex harmless as described
in Section 8.1, at the Closing, MTLM shall set aside and hold the certificates
representing the Held Back Shares issued pursuant to this Agreement.

                  (a)      MTLM may set off against the Held Back Shares any 
         loss, damage, cost or expense for which the HouTex Shareholders may be
         responsible pursuant to this Agreement (including without limitation,
         any Indemnifiable Damages for which the HouTex Shareholders may be
         responsible pursuant to this Agreement) whether or not indemnified
         pursuant to Section 8.1 of this Agreement, subject, however, to the
         following terms and conditions:

                           (1) MTLM shall give written notice to the HouTex
                  Shareholders of any claim for Indemnifiable Damages or any
                  other damages hereunder, which notice shall set forth (i) the
                  amount of Indemnifiable Damages or other loss, damage, cost or
                  expense which MTLM claims to have sustained by reason thereof,
                  and (ii) the basis of such claim;

                           (2) Such set off shall be effected on the later to
                  occur of the expiration of 10 days from the date of such
                  notice (the "Notice of Contest Period") or, if such claim is
                  contested, the date the dispute is resolved, and such set off
                  shall be charged proportionally against the shares set aside;

                           (3) If, prior to the expiration of the Notice of
                  Contest Period, the HouTex Shareholders shall notify MTLM in
                  writing of an intention to dispute the claim and if such
                  dispute is not resolved within 30 days after expiration of
                  such period (the "Resolution Period"), then MTLM may elect
                  that such dispute shall be resolved by a committee of three


                                     - 51 -
<PAGE>   59
                  arbitrators (one appointed by the HouTex Shareholders, one
                  appointed by MTLM and one appointed by the two arbitrators so
                  appointed), which shall be appointed within 60 days after the
                  expiration of the Resolution Period. The arbitrators shall
                  abide by the rules of the American Arbitration Association and
                  their decision shall be made within 45 days of being appointed
                  and shall be final and binding on all parties;

                           (4) As soon as the Held Back Shares are registered
                  and any restrictions on sale imposed under Rule 145 of the
                  Securities Act are terminated, the HouTex Shareholder may
                  instruct MTLM to sell some or all of the Held Back Shares and
                  the net proceeds thereof shall be substituted for such Held
                  Back Shares in any set off to be made by MTLM pursuant to any
                  claim hereunder subject to continued compliance with any
                  applicable securities and other regulations; and

                           (5) For purposes of this Section 8.4, the value for
                  purposes of set off of the shares of MTLM Common Stock not
                  sold as provided in clause (4) of this Section 8.4 shall be
                  valued at the average of the closing bid and asked prices of
                  MTLM's common stock on the Nasdaq National Market System on
                  the business day preceding the date of set off.

                  (b)      Except with respect to shares transferred pursuant to
         the foregoing right of set off (and in the case of such shares, until
         the same are transferred), all Held Back Shares shall be deemed to be
         owned by the HouTex Shareholders and the HouTex Shareholders shall be
         entitled to vote the same; provided, however, that, there shall also be
         deposited with MTLM subject to the terms of this Section 8.4, all
         shares of MTLM Common Stock issued to the HouTex Shareholders as a
         result of any stock dividend or stock split and all cash issuable to
         the HouTex Shareholders as a result of any cash dividend, with respect
         to the Held Back Shares. All stock and cash issued or paid upon Held
         Back Shares shall be distributed to the person or entity entitled to
         receive such Held Back Shares together with such Held Back Shares.

                  (c)      MTLM agrees to deliver to the HouTex Shareholders no 
         later than 90 days after the Effective Time any Held Back Shares then
         held by it (or proceeds from the Held Back Shares) unless there then
         remains unresolved any claim for Indemnifiable Damages or other damages
         hereunder as to which notice has been given, in which event any Held
         Back Shares remaining on deposit (or proceeds from the sale of Held
         Back Shares) after such claim shall have been satisfied shall be
         returned to the HouTex Shareholders promptly after the time of
         satisfaction.

<PAGE>   60
In addition to the Held Back Shares, MTLM and/or HouTex may set off all
Indemnifiable Damages owed by the HouTex Shareholders hereunder against either:
(a) the monthly payments of base or additional rent or against the purchase
payments for the Property due under the Lease to Mike and Sol Melnik or to their
respective successors in interest under the Lease, (b) amounts due under the
Melnik Notes, or (c) amounts due under the Clend Note; the determination of
whether to setoff first against the payments due under the Lease, the Melnik
Notes or the Clend Note shall be left to MTLM's sole discretion.

         8.5 ADJUSTMENT TO MERGER CONSIDERATION. All payments for Indemnifiable
Damages made pursuant to this Article VIII shall be treated as adjustments to
the consideration paid in the Merger under Section 1.3.

                                   ARTICLE IX

                             SECURITIES LAW MATTERS

         The parties agree as follows with respect to the sale or other
disposition after Effective Time of the MTLM Shares:

         9.1 DISPOSITION OF SHARES. The HouTex Shareholders represent and
warrant that the shares of MTLM Common Stock being acquired by them hereunder
are being acquired and will be acquired for their own respective accounts and
will not be sold or otherwise disposed of, except pursuant to (a) an exemption
from the registration requirements under the Securities Act, which does not
require the filing by the MTLM Companies with the SEC of any registration
statement, offering circular or other document, in which case the HouTex
Shareholders shall first supply to the MTLM Companies an opinion of counsel
(which counsel and opinions shall be satisfactory to the MTLM Companies) that
such exception is available, or (ii) an effective registration statement filed
by MTLM with the SEC under the Securities Act.

         9.2 LEGEND. The certificates representing the MTLM Shares shall bear
the following legend:

         THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE
         PROVISIONS OF RULE 145(D) PROMULGATED UNDER THE SECURITIES ACT OF 1933,
         AS AMENDED (THE "ACT"), AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE
         DISPOSED OF BY THE HOLDER EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION
         STATEMENT FILED UNDER THE ACT WITH RESPECT THERETO OR IN ACCORDANCE
         WITH AN OPINION OF COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE


                                     - 53 -
<PAGE>   61
         ISSUER THAT AN EXEMPTION FROM SUCH REGISTRATION IS AVAILABLE.

MTLM may, unless a registration statement is in effect covering such shares,
place stop transfer orders with its transfer agents with respect to such
certificates in accordance with federal securities laws.

         9.3      REGISTRATION RIGHTS. The HouTex Shareholders shall have the
securities registration rights set forth in the Declaration of Registration
Rights attached hereto as Exhibit "G". The HouTex Shareholders acknowledge,
agree and understand that other individuals and entities possess either
identical or similar registration rights with regard to other presently issued
MTLM Common Stock. Also, MTLM may after the date hereof issue additional shares
of Common Stock which are also subject to similar registration rights. The
existence of such registration rights may have the effect of limiting the number
of shares of MTLM Common Stock issued to HouTex Shareholders eligible for
registration under certain provisions of the Declaration of Registration Rights.

         1997, to apply an aggregate, maximum of One Million Dollars
         ($1,000,000.00) of the unpaid principal balance of the Clend Note to
         purchase MTLM Common Stock, at a price per share equal to Seventy-Five
         Percent (75%) of the average closing price of MTLM Common Stock on the
         five (5) trading days immediately preceding the date of delivery by the
         holders of the Clend Note to MTLM of a written notice (the "Category
         One Notice") of the exercise of such right signed by all of the holders
         of the Clend Note. The Category One Notice shall specify the unpaid
         principal balance of the Clend Note being so applied to the purchase of
         MTLM Common Stock. The holder of the Clend Note shall have the right to

         any public announcement by MTLM of its execution of a letter of intent
         or a definitive agreement to acquire the stock or assets of a scrap
         metal recycling company with gross revenue for its most recent fiscal
         year in excess of


                                        1
<PAGE>   2
         $150,000,000-to apply an aggregate maximum of One Million Dollars
         ($1,000,000.00) of the unpaid principal balance of the Clend Note to
         purchase MTLM Common Stock, at a price per share equal to either.

                 (a)       Five Dollars ($5.00), if the average closing price of
                           MTLM Common Stock (the "Category Two Average Closing
                           Price") on the five (5) trading days immediately
                           preceding the date of delivery by the holder of the
                           Clend Note to MTLM of a written notice (the "Category
                           Two Notice") of the exercise of such right signed by
                           the holder of the Clend Note is less than Seven
                           Dollars Twenty-Five Cents ($7.25); or

                 (b)       Five Dollars Forty-Eight Cents ($5.48), if the
                           Category Two Average Closing Price is Seven Dollars
                           Twenty-Five Cents ($7.25) or greater.

         The Category Two Notice shall specify the unpaid principal balance of
         the Clend Note being so applied to the purchase of MTLM Common Stock.
         The holder of the Clend Note shall have the right to exercise the
         Category Two Conversion Rights only three (3) times with each such
         exercise to be in an amount of at least $250,000.

         3. Escrow of Conversion Shares. If the holder of the Clend Note
         exercises its rights under Paragraphs 1 and/or 2 above to apply a
         portion of the unpaid balance of the principal of the Notes to purchase
         MTLM Common Stock, then all of the MTLM Common Stock so purchased by
         the holder of the Clend Note shall be held in escrow (the "Escrowed
         Conversion Shares") in accordance with paragraph 8 below.

         4. Acquisition Financing. MTLM has received a commitment to place
         approximately $30,000,000 in convertible MTLM subordinated debt
         instruments (the "EVEREN Financing") from EVEREN Securities ("EVEREN").
         A copy of this commitment has previously been furnished to the HouTex
         Shareholders. The Parties agree that MTLM's receipt of the EVEREN
         Financing or any other financing (whether such financing is from a
         public offering or private placement of debt or equity or from bank
         loans, excluding, however, (i) the pending financing for the Reserve
         acquisition and (ii) the senior bank debt replacement financing
         currently being negotiated by MTLM) which provides MTLM with net
         proceeds in excess of $7,000,000 which are available to fund
         acquisitions (collectively the "Acquisition Financing") prior to the
         maturity of the Notes shall have a material effect on the terms of the
         Notes and on the liquidated damages received by the HouTex Shareholders
         in the event MTLM defaults on the Notes. MTLM agrees to use its
         reasonable best efforts to obtain such Acquisition Financing from
         either EVEREN or some other financing source.

         5. Modification to Cash Consideration and Notes. The Cash Consideration
         set forth in Section 1.3 of the Merger Agreement is hereby increased
         from $500,000 to $750,000 and the respective principal amounts of the
         Melnik Notes are hereby decreased by $250,000 to reflect


                                        2
<PAGE>   3
         such increase in Cash Consideration. Furthermore, the Notes and the
         Stock Pledge and Security Agreements attached as Exhibit B-5 to the
         Merger Agreement shall be modified to provide that (i) the obligations
         reflected by the Notes and the Stock Pledge and Security Agreements are
         entered into without recourse as to MTLM in the event that MTLM uses
         its reasonable best efforts to obtain the Acquisition Financing but the
         proceeds of the Acquisition Financing are not received prior to April
         30, 1997; and (ii) the sole remedy available to the Noteholders if an
         event of default occurs and, provided MTLM has used its reasonable best
         efforts to obtain the Acquisition Financing, the proceeds of the
         Acquisition Financing have not been so received by MTLM prior to April
         30, 1997, shall be to exercise the Noteholders respective rights under
         the Stock Pledge and Security Agreements and foreclose on the HouTex
         shares pledged as collateral under the Stock Pledge and Security
         Agreements.

         6. Liquidated Damages if Acquisition Financing Does Not Occur. In the
         event (i) MTLM does not receive the proceeds of the Acquisition
         Financing prior to April 30, 1997; (ii) the Notes are not paid in full
         at or prior to their respective maturity dates; and (iii) MTLM fails to
         cure such default within the time period allowed by the Escrow
         Agreements, then the HouTex Shareholders shall be entitled to retain as
         liquidated damages only the following:

                 (a)       all Cash Consideration paid by MTLM at Closing;

                 (b)       all Limited Warrants issued to the HouTex
                           Shareholders either at or following Closing; and

                 (c)       all rights of foreclosure on the HouTex stock held as
                           collateral under the Stock Pledge and Security
                           Agreements.

         Except as set forth above, the HouTex Shareholders shall be entitled to
         no damages or other remedies at law or in equity or to pursue, directly
         or indirectly, any claims against MTLM arising from MTLM's default
         under the Notes, if MTLM does not receive the proceeds of the
         Acquisition Financing prior to April 30, 1997. All Five-Year Warrants
         and Share Consideration issued to the HouTex Shareholders at Closing
         and all Escrowed Conversion Shares issued following Closing shall be
         returned to MTLM and cancelled under the terms of the escrow
         arrangement described in paragraph 8 below.

         7. Liquidated Damages if Acquisition Financing does Occur. The Notes
         shall be amended to provide for acceleration of the due dates of the
         Notes in the event MTLM does receive the proceeds of the Acquisition
         Financing prior to April 30, 1997. The Notes shall provide that MTLM
         will have an affirmative duty to pay the Notes in full within five (5)
         business days after the receipt of the proceeds of the Acquisition
         Financing. If MTLM fails to pay the Notes after acceleration, then the
         HouTex Shareholders shall be entitled to either:

                 (a)       retain as liquidated damages the following:



                                        3
<PAGE>   4

                           (iii)     all rights of foreclosure on the HouTex
                                     stock held as collateral under the Stock
                                     Pledge and Security Agreements;

                                     E.      all Escrowed Conversion Shares
                                             issued to the HouTex Shareholders

                  (ii)     seek specific performance under the Notes.

         Except as set forth above, the HouTex Shareholders shall be entitled to
         no damages or other remedies at law or in equity or to pursue, directly
         or indirectly, any claims against MTLM arising from MTLM's default
         under the Notes, if MTLM does receive the proceeds of Acquisition
         Financing prior to April 30, 1997. All Five-Year Warrants, Share
         Consideration and Escrowed Conversion Shares shall be delivered to the

                                        4
<PAGE>   5

         8. Escrow. The Parties agree that the Escrow Agreements shall be
         modified and expanded to provide for the escrow at Closing of (i) the
         Five-Year Warrants, (ii) the Share Consideration and the escrow
         thereafter of the Escrowed Conversion Shares, together with the shares
         of HouTex common stock pledged to the HouTex Shareholders under the
         Stock Pledge and Security Agreements. The Escrow Agreements, as
         modified, shall provide that, in the event MTLM defaults on the Notes
         and the HouTex Shareholders are only entitled to receive the liquidated
         damages specified under paragraph 6 above, then the escrow agent under
         the Escrow Agreements shall return the Five-Year Warrants, the Share
         Consideration, and the Escrowed Conversion Shares to MTLM for
         cancellation and shall return the escrowed HouTex common stock owned by
         MTLM to the HouTex Shareholders, subject to the terms and conditions of
         the Stock Pledge and Security Agreement. Similarly, the Escrow
         Agreements, as modified, shall provide that in the event MTLM defaults
         on the Notes and the HouTex Shareholders are entitled to receive the
         damages set forth in paragraph 7 above, the escrow agent under the
         Escrow Agreements shall deliver the Five-Year Warrants, the Share
         Consideration and the Escrowed Conversion Shares to the HouTex
         Shareholders.

         9. Termination of Lease and Guarantee Relationship. In the event MTLM
         fails to pay the Notes when they mature and the HouTex Shareholders
         foreclose on the stock of HouTex, the Lease will terminate and MTLM
         will be released from its guarantee obligations under the Lease and on
         all other obligations of HouTex which have been guaranteed by MTLM;
         provided, however, MTLM agrees that, in the event it guarantees
         HouTex's revolving credit obligations to NationsBank of Texas, N.A., it
         will agree to remain liable to NationsBank under such guarantee
         agreement. The HouTex Shareholders agree to use their reasonable best
         efforts to obtain a release of MTLM's guarantee obligation from
         NationsBank. In the event MTLM fails to pay the Notes when they mature
         and the HouTex Shareholders foreclose on the stock of HouTex owned by
         MTLM, but the HouTex Shareholders are unable to obtain a release of
         MTLM's guarantee obligation to NationsBank, MTLM shall have and retain
         subrogation rights against HouTex and the HouTex Shareholders in the
         event MTLM thereafter is required to pay any funds to NationsBank as a
         guarantor for HouTex.

         10. Modifications to Documents. The Parties agree that each of the
         Exhibits to the Merger Agreement and all other documents described in,
         or contemplated by, the Merger Agreement will be modified, amended, or
         restated in a manner consistent with the provisions of this First
         Amendment. The form of all such Exhibits and other documents, as
         modified, shall be mutually agreeable to all Parties and their
         respective legal counsel.

B.       Ratification of Merger Agreement. Except as specifically modified by 
the provisions of this First Amendment, all terms and conditions of the Merger
Agreement are hereby ratified by the Parties.

         IN WITNESS WHEREOF, the parties have executed this agreement on the
date first written above.

                                    GUARANTY

         THIS GUARANTY is dated as of January 7, 1997, by GERARD M. JACOBS
("Jacobs"), T. BENJAMIN JENNINGS ("Jennings"), DONALD MOOREHEAD ("D.
Moorehead"), HAROLD RUBENSTEIN ("Rubenstein"), GEORGE MOOREHEAD ("G. Moorehead")
and RAYMOND ZACK ("Zack") (Jacobs, Jennings, D. Moorehead, Rubenstein, G.
Moorehead and Zack are hereinafter referred to individually as a "Guarantor")
and collectively as the "Guarantors") to and for the benefit of LASALLE NATIONAL
BANK, a national banking association ("Lender").

                                    RECITALS:

         A. Pursuant to the terms and conditions of a certain Loan Agreement of
even date herewith (the "Loan Agreement") by and among HouTex, Lender and Metal
Management, Inc., a Delaware corporation ("MMI"), Lender has agreed, among other
things, to loan to MMI the principal amount of $6,500,000 (the "Loan").

         B. A condition precedent to Lender's extension of the Loan to MMI is
the execution and delivery of (i) this Guaranty, (ii) that certain Note of even
date herewith (the "Note") made by MMI and payable to the order of Lender to
evidence the Loan, and (iii) the other Loan Documents (as defined in the Loan
Agreement). All capitalized terms used herein which are not otherwise defined
shall have the meanings ascribed thereto in the Loan Agreement.

         NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which hereby are acknowledged, each Guarantor hereby agrees as
follows:

         1. GUARANTY OF PAYMENT. Each Guarantor hereby unconditionally and
irrevocably guaranties to Lender the punctual payment and performance when due,
whether at stated maturity or by acceleration or otherwise, of the indebtedness
and other obligations of MMI to Lender evidenced by the Note and any other
obligations or amounts that may become owing by MMI under the Loan Documents
(such indebtedness, obligations and other amounts are hereinafter referred to as
"MMI's Obligations"). Each Guarantor agrees that this Guaranty is a present and
continuing guaranty of payment and not of collectibility, and that Lender shall
not be required to prosecute collection, enforcement or other remedies against
MMI or any other guarantor of MMI's Obligations, or to enforce or resort to any
collateral for the repayment of MMI's Obligations or other rights or remedies
pertaining thereto, before calling on such Guarantor for payment. Each Guarantor
agrees that if for any reason MMI shall fail or be unable to pay, punctually and
fully, any of MMI's Obligations, such Guarantor shall pay such obligations to
Lender in full immediately upon demand. Each Guarantor agrees that one or more
successive actions may be brought against such Guarantor, as often as Lender
deems advisable, until all of MMI's Obligations are paid and performed in full.

         2. REPRESENTATIONS AND WARRANTIES. The following shall constitute
representations and warranties of each Guarantor and each Guarantor hereby
acknowledges that Lender intends to make the Loan in reliance thereon:
<PAGE>   2
                  (a) Such Guarantor is not in default and no event has occurred
         that with the passage of time and/or the giving of notice will
         constitute a default under any agreement to which such Guarantor is a
         party, the effect of which will impair performance by such Guarantor of
         his or its respective obligations under this Guaranty. Neither the
         execution and delivery of this Guaranty nor compliance with the terms
         and provisions hereof will violate any applicable law, rule,
         regulation, judgment, decree or order, or will conflict with or result
         in any breach of any of the terms, covenants, conditions or provisions
         of any indenture, mortgage, deed of trust, instrument, document,
         agreement or contract of any kind that creates, represents, evidences
         or provides for any lien, charge or encumbrance upon any of the
         property or assets of such Guarantor, or any other indenture, mortgage,
         deed of trust, instrument, document, agreement or contract of any kind
         to which such Guarantor is a party or to which such Guarantor or the
         property of such Guarantor may be subject.

                  (b) There is not any litigation, arbitration, governmental or
         administrative proceedings, actions, examinations, claims or demands
         pending, or to such Guarantor's knowledge, threatened that could
         adversely affect performance by such Guarantor of his or its respective
         obligations under this Guaranty.

                  (c) Neither this Guaranty nor any statement or certification
         as to facts previously furnished or required herein to be furnished to
         Lender by such Guarantor, contains any material inaccuracy or untruth
         in any representation, covenant or warranty or omits to state a fact
         material to this Guaranty.

         3. CONTINUING GUARANTY. Each Guarantor agrees that the obligations of
such Guarantor pursuant to Section 1 above and any other provision of any of the
Loan Documents shall be primary obligations, shall not be subject to any
counterclaim, set-off, abatement, deferment or defense based upon any claim that
such Guarantor may have against Lender, MMI, any other guarantor of MMI's
Obligations or any other person or entity, and shall remain in full force and
effect without regard to, and shall not be released, discharged or affected in
any way by, any circumstance or condition (whether or not such Guarantor shall
have any knowledge thereof), including without limitation:

                  (a) any lack of validity or enforceability of the Note or any
         of the other Loan Documents;

                  (b) any termination, amendment, modification or other change
         in the Note or any of the other Loan Documents, including, without
         limitation, any modification of the interest rate(s) described therein;

                  (c) any furnishing, exchange, substitution or release of any
         collateral securing repayment of the Loan, or any failure to perfect
         any lien in such collateral;

                  (d) any failure, omission or delay on the part of MMI, any
         Guarantor, any other guarantor of MMI's Obligations or Lender to
         conform or comply with any term of any of the

                                       -2-
<PAGE>   3
         Loan Documents or any failure of Lender to give notice of any Event of
         Default (as defined in the Loan Agreement);

                  (e) any waiver, compromise, release, settlement or extension
         of time of payment or performance or observance of any of the
         obligations or agreements contained in the Note or any of the other
         Loan Documents;

                  (f) any action or inaction by Lender under or in respect of
         the Note or any of the other Loan Documents, any failure, lack of
         diligence, omission or delay on the part of Lender to enforce, assert
         or exercise any right, power or remedy conferred on it in the Note or
         any of the other Loan Documents, or any other action or inaction on the
         part of Lender;

                  (g) any voluntary or involuntary bankruptcy, insolvency,
         reorganization, arrangement, readjustment, assignment for the benefit
         of creditors, composition, receivership, liquidation, marshalling of
         assets and liabilities or similar events or proceedings with respect to
         MMI, any Guarantor or any other guarantor of MMI's Obligations, as
         applicable, or any of their respective property or creditors, or any
         action taken by any trustee or receiver or by any court in any such
         proceeding;

                  (h) any merger or consolidation of MMI into or with any
         entity, or any sale, lease or transfer of any of the assets of MMI, any
         Guarantor or any other guarantor of MMI's Obligations to any other
         person or entity;

                  (i) any change in the ownership of MMI or any change in the
         relationship between MMI, any Guarantor or any other guarantor of MMI's
         Obligations, or any termination of any such relationship;

                  (j) any release or discharge by operation of law of MMI or any
         other guarantor of MMI's Obligations from any obligation or agreement
         contained in any of the Loan Documents; or

                  (k) any other occurrence, circumstance, happening or event,
         whether similar or dissimilar to the foregoing and whether foreseen or
         unforeseen, which otherwise might constitute a legal or equitable
         defense or discharge of the liabilities of a guarantor or surety or
         which otherwise might limit recourse against MMI or any Guarantor.

         4. WAIVERS. Each Guarantor unconditionally waives (i) notice of any of
the matters referred to in Section 3 above, (ii) all notices which may be
required by statute, rule of law or otherwise, now or hereafter in effect, to
preserve intact any rights against such Guarantor, including, without
limitation, any demand, presentment and protest, proof of notice of non-payment
under any of the Loan Documents and notice of any Event of Default or any
failure on the part of MMI, any Guarantor or any other guarantor of MMI's
Obligations to perform or comply with any covenant, agreement, term or condition
of any of the Loan Documents, (iii) any right to the enforcement, assertion or
exercise against MMI, any Guarantor or any other guarantor of MMI's Obligations
of any right or remedy conferred under any of the Loan Documents, (iv) any
requirement of diligence

                                       -3-
<PAGE>   4
on the part of any person or entity, (v) to the fullest extent permitted by law
and except as otherwise expressly provided in this Guaranty or the other Loan
Documents, any claims based on allegations that Lender has failed to act in a
commercially reasonable manner, (vi) any requirement to exhaust any remedies or
to mitigate the damages resulting from any default under any of the Loan
Documents, and (vii) any notice of any sale, transfer or other disposition of
any right, title or interest of Lender under any of the Loan Documents.

         5. SUBORDINATION. Each Guarantor agrees that any and all present and
future debts and obligations of MMI to such Guarantor hereby are subordinated to
the claims of Lender and hereby are assigned by such Guarantor to Lender as
security for MMI's Obligations and such Guarantor's obligations under this
Guaranty.

         6. SUBROGATION WAIVER. Until MMI's Obligations are paid in full and all
periods under applicable bankruptcy law for the contest of any payment by any
Guarantor or MMI as a preferential or fraudulent payment have expired, each
Guarantor knowingly, and with advice of counsel, waives, relinquishes, releases
and abandons all rights and claims to indemnification, contribution,
reimbursement, subrogation and payment which such Guarantor may now or hereafter
have by and from MMI and the successors and assigns of MMI, for any payments
made by such Guarantor to Lender, including, without limitation, any rights
which might allow MMI, MMI's successors, a creditor of MMI, or a trustee in
bankruptcy of MMI to claim in bankruptcy or any other similar proceedings that
any payment made by MMI or MMI's successors and assigns to Lender was on behalf
of or for the benefit of such Guarantor and that such payment is recoverable by
MMI, a creditor or trustee in bankruptcy of MMI as a preferential payment,
fraudulent conveyance, payment of an insider or any other classification of
payment which may otherwise be recoverable from Lender.

         7. REINSTATEMENT. The obligations of the Guarantors pursuant to this
Guaranty shall continue to be effective or automatically be reinstated, as the
case may be, if at any time payment of any of MMI's Obligations or the
Guarantors' obligations under this Guaranty is rescinded or otherwise must be
restored or returned by Lender upon the insolvency, bankruptcy, dissolution,
liquidation or reorganization of any Guarantor or MMI or otherwise, all as
though such payment had not been made.

         8. FINANCIAL STATEMENTS. Each Guarantor hereby represents and warrants
to Lender that (a) the financial statements of such Guarantor previously
submitted to Lender are true, complete and correct in all material respects,
disclose all actual and contingent liabilities, and fairly present the financial
condition of such Guarantor, and do not contain any untrue statement of a
material fact or omit to state a fact material to the financial statements
submitted or this Guaranty and (b) no material adverse change has occurred in
the financial statements from the dates thereof until the date hereof. Each
Guarantor shall furnish to Lender financial statements in accordance with the
terms and conditions set forth in the Loan Agreement.

         9. SUCCESSORS AND ASSIGNS; JOINT AND SEVERAL LIABILITIES. This Guaranty
shall inure to the benefit of Lender and its successors and assigns. This
Guaranty shall be binding on each

                                       -4-
<PAGE>   5
Guarantor and the heirs, legatees, successors and assigns of such Guarantor. The
Guarantors shall be jointly and severally liable for the obligations set forth
in this Guaranty.

         10. NO WAIVER OF RIGHTS. No delay or failure on the part of Lender to
exercise any right, power or privilege under this Guaranty or any of the other
Loan Documents shall operate as a waiver thereof, and no single or partial
exercise of any right, power or privilege shall preclude any other or further
exercise thereof or the exercise of any other power or right, or be deemed to
establish a custom or course of dealing or performance between the parties
hereto. The rights and remedies herein provided are cumulative and not exclusive
of any rights or remedies provided by law. No notice to or demand on any
Guarantor in any case shall entitle such Guarantor to any other or further
notice or demand in the same, similar or other circumstance.

         11. MODIFICATION. The terms of this Guaranty may be waived, discharged,
or terminated only by an instrument in writing signed by the party against which
enforcement of the change, waiver, discharge or termination is sought. No
amendment, modification, waiver or other change of any of the terms of this
Guaranty shall be effective without the prior written consent of Lender.

         12. JOINDER. Each Guarantor agrees that any action to enforce this
Guaranty may be brought against such Guarantor without any joinder of MMI or any
other guarantor of MMI's Obligations in such action.

         13. SEVERABILITY. In the event that any provision of this Guaranty is
deemed to be invalid by reason of the operation of law, or by reason of the
interpretation placed thereon by any administrative agency or any court, the
Guarantors and Lender shall negotiate an equitable adjustment in the provisions
of the same in order to effect, to the maximum extent permitted by law, the
purpose of this Guaranty and the validity and enforceability of the remaining
provisions, or portions or applications thereof, shall not be affected thereby
and shall remain in full force and effect.

         14. APPLICABLE LAW. This Guaranty shall be governed as to validity,
interpretation, effect and in all other respects by laws and decisions of the
State of Illinois.

         15. NOTICE. All notices, communications and waivers under this Guaranty
shall be in writing and shall be (i) delivered in person or (ii) mailed, postage
prepaid, either by registered or certified mail, return receipt requested, or
(iii) sent by overnight express carrier, addressed in each case as follows:

                                    GUARANTY

         THIS GUARANTY is dated as of January 7, 1997, by METAL MANAGEMENT INC.,
a Delaware corporation ("MMI"), GERARD M. JACOBS ("Jacobs"), T. BENJAMIN
JENNINGS ("Jennings"), DONALD MOOREHEAD ("D. Moorehead"), HAROLD RUBENSTEIN
("Rubenstein"), GEORGE MOOREHEAD ("G. Moorehead") and RAYMOND ZACK ("Zack")
(MMI, Jacobs, Jennings, D. Moorehead, Rubenstein, G. Moorehead and Zack are
hereinafter referred to individually as a "Guarantor" and collectively as the
"Guarantors") to and for the benefit of LASALLE NATIONAL BANK, a national
banking association ("Lender").

                                    RECITALS:

         A. Pursuant to the terms and conditions of a certain Loan Agreement of
even date herewith (the "Loan Agreement") by and among MMI, Lender and HouTex
Metals Company, Inc., a Texas corporation ("HouTex"), Lender has agreed, among
other things, to make available to HouTex a working capital line of credit in
the maximum principal amount of $3,500,000 (any and all amounts drawn by HouTex
under said working capital line of credit are hereinafter collectively referred
to as the "Loan").

         B. A condition precedent to Lender's extension of the Loan to HouTex is
the execution and delivery of (i) this Guaranty, (ii) that certain Note of even
date herewith (the "Note") made by HouTex and payable to the order of Lender to
evidence the Loan, and (iii) the other Loan Documents (as defined in the Loan
Agreement). All capitalized terms used herein which are not otherwise defined
shall have the meanings ascribed thereto in the Loan Agreement.

         NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which hereby are acknowledged, each Guarantor hereby agrees as
follows:

         1. GUARANTY OF PAYMENT. Each Guarantor hereby unconditionally and
irrevocably guaranties to Lender the punctual payment and performance when due,
whether at stated maturity or by acceleration or otherwise, of the indebtedness
and other obligations of HouTex to Lender evidenced by the Note and any other
obligations or amounts that may become owing by HouTex under the Loan Documents
(such indebtedness, obligations and other amounts are hereinafter referred to as
"HouTex's Obligations"). Each Guarantor agrees that this Guaranty is a present
and continuing guaranty of payment and not of collectibility, and that Lender
shall not be required to prosecute collection, enforcement or other remedies
against HouTex or any other guarantor of HouTex's Obligations, or to enforce or
resort to any collateral for the repayment of HouTex's Obligations or other
rights or remedies pertaining thereto, before calling on such Guarantor for
payment. Each Guarantor agrees that if for any reason HouTex shall fail or be
unable to pay, punctually and fully, any of HouTex's Obligations, such Guarantor
shall pay such obligations to Lender in full immediately upon demand. Each
Guarantor agrees that one or more successive actions may be brought against such
Guarantor, as often as Lender deems advisable, until all of HouTex's Obligations
are paid and performed in full.

         2. REPRESENTATIONS AND WARRANTIES. The following shall constitute
representations and warranties of each Guarantor and each Guarantor hereby
acknowledges that Lender intends to make the Loan in reliance thereon:


                                      
<PAGE>   2
                  (a) Such Guarantor is not in default and no event has occurred
         that with the passage of time and/or the giving of notice will
         constitute a default under any agreement to which such Guarantor is a
         party, the effect of which will impair performance by such Guarantor of
         his or its respective obligations under this Guaranty. Neither the
         execution and delivery of this Guaranty nor compliance with the terms
         and provisions hereof will violate any applicable law, rule,
         regulation, judgment, decree or order, or will conflict with or result
         in any breach of any of the terms, covenants, conditions or provisions
         of any indenture, mortgage, deed of trust, instrument, document,
         agreement or contract of any kind that creates, represents, evidences
         or provides for any lien, charge or encumbrance upon any of the
         property or assets of such Guarantor, or any other indenture, mortgage,
         deed of trust, instrument, document, agreement or contract of any kind
         to which such Guarantor is a party or to which such Guarantor or the
         property of such Guarantor may be subject.

                  (b) There is not any litigation, arbitration, governmental or
         administrative proceedings, actions, examinations, claims or demands
         pending, or to such Guarantor's knowledge, threatened that could
         adversely affect performance by such Guarantor of his or its respective
         obligations under this Guaranty.

                  (c) Neither this Guaranty nor any statement or certification
         as to facts previously furnished or required herein to be furnished to
         Lender by such Guarantor, contains any material inaccuracy or untruth
         in any representation, covenant or warranty or omits to state a fact
         material to this Guaranty.

         3. CONTINUING GUARANTY. Each Guarantor agrees that the obligations of
such Guarantor pursuant to Section 1 above and any other provision of any of the
Loan Documents shall be primary obligations, shall not be subject to any
counterclaim, set-off, abatement, deferment or defense based upon any claim that
such Guarantor may have against Lender, HouTex, any other guarantor of HouTex's
Obligations or any other person or entity, and shall remain in full force and
effect without regard to, and shall not be released, discharged or affected in
any way by, any circumstance or condition (whether or not such Guarantor shall
have any knowledge thereof), including without limitation:

                  (a) any lack of validity or enforceability of the Note or any
         of the other Loan Documents;

                  (b) any termination, amendment, modification or other change
         in the Note or any of the other Loan Documents, including, without
         limitation, any modification of the interest rate(s) described therein;

                  (c) any furnishing, exchange, substitution or release of any
         collateral securing repayment of the Loan, or any failure to perfect
         any lien in such collateral;

                  (d) any failure, omission or delay on the part of HouTex, any
         Guarantor, any other guarantor of HouTex's Obligations or Lender to
         conform or comply with any term of any of the Loan Documents or any
         failure of Lender to give notice of any Event of Default (as defined in
         the Loan Agreement);

                                     - 2 -

<PAGE>   3
                  (e) any waiver, compromise, release, settlement or extension
         of time of payment or performance or observance of any of the
         obligations or agreements contained in the Note or any of the other
         Loan Documents;

                  (f) any action or inaction by Lender under or in respect of
         the Note or any of the other Loan Documents, any failure, lack of
         diligence, omission or delay on the part of Lender to enforce, assert
         or exercise any right, power or remedy conferred on it in the Note or
         any of the other Loan Documents, or any other action or inaction on the
         part of Lender;

                  (g) any voluntary or involuntary bankruptcy, insolvency,
         reorganization, arrangement, readjustment, assignment for the benefit
         of creditors, composition, receivership, liquidation, marshalling of
         assets and liabilities or similar events or proceedings with respect to
         HouTex, any Guarantor or any other guarantor of HouTex's Obligations,
         as applicable, or any of their respective property or creditors, or any
         action taken by any trustee or receiver or by any court in any such
         proceeding;

                  (h) any merger or consolidation of HouTex into or with any
         entity, or any sale, lease or transfer of any of the assets of HouTex,
         any Guarantor or any other guarantor of HouTex's Obligations to any
         other person or entity;

                  (i) any change in the ownership of HouTex or any change in the
         relationship between HouTex, any Guarantor or any other guarantor of
         HouTex's Obligations, or any termination of any such relationship;

                  (j) any release or discharge by operation of law of HouTex or
         any other guarantor of HouTex's Obligations from any obligation or
         agreement contained in any of the Loan Documents; or

                  (k) any other occurrence, circumstance, happening or event,
         whether similar or dissimilar to the foregoing and whether foreseen or
         unforeseen, which otherwise might constitute a legal or equitable
         defense or discharge of the liabilities of a guarantor or surety or
         which otherwise might limit recourse against HouTex or any Guarantor.

         4. WAIVERS. Each Guarantor unconditionally waives (i) notice of any of
the matters referred to in Section 3 above, (ii) all notices which may be
required by statute, rule of law or otherwise, now or hereafter in effect, to
preserve intact any rights against such Guarantor, including, without
limitation, any demand, presentment and protest, proof of notice of non-payment
under any of the Loan Documents and notice of any Event of Default or any
failure on the part of HouTex, any Guarantor or any other guarantor of HouTex's
Obligations to perform or comply with any covenant, agreement, term or condition
of any of the Loan Documents, (iii) any right to the enforcement, assertion or
exercise against HouTex, any Guarantor or any other guarantor of HouTex's
Obligations of any right or remedy conferred under any of the Loan Documents,
(iv) any requirement of diligence on the part of any person or entity, (v) to
the fullest extent permitted by law and except as otherwise expressly provided
in this Guaranty or the other Loan Documents, any claims based on allegations
that Lender has failed to act in a commercially reasonable manner, (vi) any
requirement to exhaust any remedies or to mitigate the damages resulting from
any default under any of the Loan 

                                     - 3 -

<PAGE>   4
Documents, and (vii) any notice of any sale, transfer or other disposition of
any right, title or interest of Lender under any of the Loan Documents.

         5. SUBORDINATION. Each Guarantor agrees that any and all present and
future debts and obligations of HouTex to such Guarantor hereby are subordinated
to the claims of Lender and hereby are assigned by such Guarantor to Lender as
security for HouTex's Obligations and such Guarantor's obligations under this
Guaranty.

         6. SUBROGATION WAIVER. Until HouTex's Obligations are paid in full and
all periods under applicable bankruptcy law for the contest of any payment by
any Guarantor or HouTex as a preferential or fraudulent payment have expired,
each Guarantor knowingly, and with advice of counsel, waives, relinquishes,
releases and abandons all rights and claims to indemnification, contribution,
reimbursement, subrogation and payment which such Guarantor may now or hereafter
have by and from HouTex and the successors and assigns of HouTex, for any
payments made by such Guarantor to Lender, including, without limitation, any
rights which might allow HouTex, HouTex's successors, a creditor of HouTex, or a
trustee in bankruptcy of HouTex to claim in bankruptcy or any other similar
proceedings that any payment made by HouTex or HouTex's successors and assigns
to Lender was on behalf of or for the benefit of such Guarantor and that such
payment is recoverable by HouTex, a creditor or trustee in bankruptcy of HouTex
as a preferential payment, fraudulent conveyance, payment of an insider or any
other classification of payment which may otherwise be recoverable from Lender.

         7. REINSTATEMENT. The obligations of the Guarantors pursuant to this
Guaranty shall continue to be effective or automatically be reinstated, as the
case may be, if at any time payment of any of HouTex's Obligations or the
Guarantors' obligations under this Guaranty is rescinded or otherwise must be
restored or returned by Lender upon the insolvency, bankruptcy, dissolution,
liquidation or reorganization of any Guarantor or HouTex or otherwise, all as
though such payment had not been made.

         8. FINANCIAL STATEMENTS. Each Guarantor hereby represents and warrants
to Lender that (a) the financial statements of such Guarantor previously
submitted to Lender are true, complete and correct in all material respects,
disclose all actual and contingent liabilities, and fairly present the financial
condition of such Guarantor, and do not contain any untrue statement of a
material fact or omit to state a fact material to the financial statements
submitted or this Guaranty and (b) no material adverse change has occurred in
the financial statements from the dates thereof until the date hereof. Each
Guarantor shall furnish to Lender financial statements in accordance with the
terms and conditions set forth in the Loan Agreement.

         9. SUCCESSORS AND ASSIGNS; JOINT AND SEVERAL LIABILITIES. This Guaranty
shall inure to the benefit of Lender and its successors and assigns. This
Guaranty shall be binding on each Guarantor and the heirs, legatees, successors
and assigns of such Guarantor. The Guarantors shall be jointly and severally
liable for the obligations set forth in this Guaranty.

         10. NO WAIVER OF RIGHTS. No delay or failure on the part of Lender to
exercise any right, power or privilege under this Guaranty or any of the other
Loan Documents shall operate as a waiver thereof, and no single or partial
exercise of any right, power or privilege shall preclude any other or 



                                     - 4 -

<PAGE>   5
further exercise thereof or the exercise of any other power or right, or be
deemed to establish a custom or course of dealing or performance between the
parties hereto. The rights and remedies herein provided are cumulative and not
exclusive of any rights or remedies provided by law. No notice to or demand on
any Guarantor in any case shall entitle such Guarantor to any other or further
notice or demand in the same, similar or other circumstance.

         11. MODIFICATION. The terms of this Guaranty may be waived, discharged,
or terminated only by an instrument in writing signed by the party against which
enforcement of the change, waiver, discharge or termination is sought. No
amendment, modification, waiver or other change of any of the terms of this
Guaranty shall be effective without the prior written consent of Lender.

         12. JOINDER. Each Guarantor agrees that any action to enforce this
Guaranty may be brought against such Guarantor without joinder of HouTex or any
other guarantor of HouTex's Obligations in such action.

         13. SEVERABILITY. In the event that any provision of this Guaranty is
deemed to be invalid by reason of the operation of law, or by reason of the
interpretation placed thereon by any administrative agency or any court, the
Guarantors and Lender shall negotiate an equitable adjustment in the provisions
of the same in order to effect, to the maximum extent permitted by law, the
purpose of this Guaranty and the validity and enforceability of the remaining
provisions, or portions or applications thereof, shall not be affected thereby
and shall remain in full force and effect.

         14. APPLICABLE LAW. This Guaranty shall be governed as to validity,
interpretation, effect and in all other respects by laws and decisions of the
State of Illinois.

         15. NOTICE. All notices, communications and waivers under this Guaranty
shall be in writing and shall be (i) delivered in person or (ii) mailed, postage
prepaid, either by registered or certified mail, return receipt requested, or

                                 LOAN AGREEMENT

         THIS LOAN AGREEMENT is dated as of January 7, 1997, by and among METAL
MANAGEMENT, INC., a Delaware corporation ("MMI"), HOUTEX METALS COMPANY, INC., a
Texas corporation ("HouTex") (jointly, the "Borrowers"), and LASALLE NATIONAL
BANK, a national banking association ("Lender").

                                    RECITALS:

         A. MMI desires to obtain a $6,500,000 term loan from Lender to provide
funds to MMI to acquire certain entities currently engaged in businesses related
to the business of MMI, including HouTex, and to provide MMI with necessary
working capital.

         B. HouTex desires to obtain a $3,500,000 revolving line of credit from
Lender to refinance certain existing indebtedness of HouTex and to provide
HouTex with necessary working capital.

         C. Lender is willing to make such loans subject to the terms and
conditions set forth herein.

         NOW, THEREFORE, it is agreed as follows:


1.       DEFINITIONS AND DETERMINATIONS.

         1.1 Definitions. As used in this Loan Agreement and in the other Loan
Documents, unless otherwise expressly indicated herein or therein, the following
terms shall have the following meanings (such meanings to be applicable equally
both to the singular and plural terms defined):

                  Accountants: any independent certified public accounting firm
         selected by the Borrowers and reasonably satisfactory to Lender.

                  Accounts: all of HouTex's now existing or hereafter arising or
         acquired accounts receivable, chattel paper, contract rights, letters
         of credit, instruments, documents and all other rights to payment,
         however created, including, without limitation, any right to payment
         for goods sold or leased or for services rendered, whether arising out
         of the sale of inventory or otherwise and whether or not it has been
         earned by performance, and any and all notes, drafts, acceptances,
         general intangibles and other obligations arising out of or
         representing a right to payment, however created.

                  Affiliate: any Person that directly or indirectly, through one
         or more intermediaries, controls or is controlled by or is under common
         control with another Person. The term "control" means possession,
         directly or indirectly, of the power to direct or cause the direction
         of the management and policies of a Person, whether through the
         ownership of voting securities, by contract or otherwise. For the
         purposes hereof, any Person which owns 
<PAGE>   7
         or controls, directly or indirectly, 10% or more of the voting
         securities of another Person shall be deemed to "control" such Person.

                  Borrowing Base: at any time and subject to change from time to
         time in Lender's reasonable discretion following notice to Borrower,
         the sum of (i) 90% of Eligible Accounts, plus (ii) 65% of the Value of
         Eligible Inventory.

                  Borrowing Base Certificate: a certificate of HouTex in a form
         satisfactory to Lender summarizing the Eligible Accounts and Eligible
         Inventory and including (a) a calculation of the Borrowing Base,
         together with any supporting documentation requested by Lender, and (b)
         a certified statement by the chief financial officer or president of
         HouTex that (i) to the best knowledge of such Person, no HouTex Event
         of Default or any other event or condition that, with the giving of
         notice or the lapse of time, or both, would become a HouTex Event of
         Default then exists, and (ii) the representations and warranties
         pertaining to HouTex set forth in this Loan Agreement are true and
         correct in all material respects as of the date of such certificate as
         though remade on such date.

                  Borrowers' Obligations: (i) any and all Indebtedness due or to
         become due, now existing or howsoever arising of the Borrowers to
         Lender pursuant to the terms of this Loan Agreement or the other Loan
         Documents, and (ii) the performance of the covenants of the Borrowers
         contained in this Loan Agreement and the other Loan Documents.

2.       LOANS AND TERMS OF PAYMENT.

         2.1      Revolving Loan.

                  2.1.1 Amount. The Revolver is a revolving loan which shall be
         made available to HouTex by Lender from time to time on and after the
         Closing Date through the day immediately preceding the Maturity Date
         (or the Extended Maturity Date, if applicable) in the maximum principal
         amount outstanding at any one time equal to the Maximum Revolving Loan
         Amount at such time. Subject to the limitations set forth in this
         Section 2, from the Closing Date through the day immediately preceding
         the Maturity Date (or the Extended Maturity Date, if applicable),
         HouTex may reborrow all or any portion of the Revolver that is repaid
         or prepaid.

                  2.1.2 Procedure for Borrowing. Each request for a Revolver
         Advance shall be irrevocable and shall be made by HouTex in writing or
         by telephone and shall only be acceptable if made by one of the Persons
         listed on Exhibit E. If a request for a Revolver Advance is made prior
         to 1:00 p.m. Chicago time on a Business Day, then such Revolver Advance
         shall be made by Lender on the date of such request. If such request is
         made at or after 1:00 p.m. Chicago time, then such Revolver Advance
         shall be made by Lender on the next Business Day. Each request for a
         Revolver Advance shall be deemed a certification by HouTex that no
         HouTex Event of Default or event or circumstance that with the passage
         of time, the giving of notice or both would constitute a HouTex Event
         of Default then exists or will be created if the requested Revolver
         Advance is made. Lender shall not be obligated to make any Revolver
         Advance if (i) a HouTex Event of Default or event or circumstance that
         with the passage of time, the giving of notice or both would constitute
         a HouTex Event of Default then exists or will be created if the
         requested Revolver Advance is made, or (ii) after making such Revolver
         Advance, the outstanding aggregate principal amount of the Revolver
         will exceed the Maximum Revolving Loan Amount.

                  2.1.3 Interest Payments. Except as otherwise provided herein
         or in the Revolver Note, accrued and unpaid interest on the outstanding
         principal balance of the Revolver shall be due and payable monthly in
         arrears on the first Business Day of each month commencing February
         1997.

                  2.1.4 Principal Payment. The outstanding principal balance of
         the Revolver shall be paid in full not later than the Maturity Date (or
         the Extended Maturity Date, if applicable).

                  2.1.5 Revolver Note. HouTex shall execute and deliver to
         Lender on the Closing Date the Revolver Note to evidence the Revolver.

                  2.1.6 Use of Proceeds of Revolver. The proceeds of the
         Revolver shall be used by HouTex to refinance certain existing
         indebtedness of HouTex and to provide working capital.

                                       10
<PAGE>   16
                  2.1.7 Mandatory Prepayment. If the outstanding principal
         balance of the Revolver at any time exceeds the amount of the Maximum
         Revolving Loan Amount at such time, HouTex shall immediately repay the
         amount of such excess without notice or demand.

         2.2      Term Loan.

                  2.2.1 Amount of Term Loan. Subject to the terms and conditions
         set forth in this Loan Agreement, Lender hereby agrees to make to MMI a
         term loan on the Closing Date (the "Term Loan") in the principal amount
         of $6,500,000.

                  2.2.2 Principal and Interest Payments; Maturity.

                           (i) Except as otherwise provided herein or in the
                  Term Note, accrued and unpaid interest on the outstanding
                  principal balance of the Term Loan shall be due and payable
                  monthly in arrears on the first Business Day of each month
                  commencing February 1997.

                           (ii) The remaining unpaid principal balance of the
                  Term Loan, together with all accrued and unpaid interest
                  thereon, if not sooner declared to be due in accordance with
                  the provisions of this Loan Agreement, shall be due and
                  payable in full on the Maturity Date (or the Extended Maturity
                  Date, if applicable).

                  2.2.3 Term Note. MMI shall execute and deliver to Lender on
         the Closing Date the Term Note to evidence the Term Loan.

         2.3 General Interest Provisions.

                  2.3.1 Interest Rate. The principal balance of the Loans
         outstanding from time to time shall bear interest at the per annum
         rates set forth in the Notes.

                  2.3.2 Interest Computation. Interest shall be (a) computed on
         the basis of a year consisting of 360 days and (b) payable for the
         actual number of days during the period for which interest is being
         charged.

                  2.3.3 Maximum Interest. Notwithstanding any provision to the
         contrary contained herein or in any of the other Loan Documents, Lender
         shall not collect a rate of interest on any obligation or liability due
         and owing by the Borrowers to Lender in excess of the maximum contract
         rate of interest permitted by applicable law. Lender and the Borrowers
         have agreed that the interest laws of the State of Illinois shall
         govern the relationship between them, but in the event of a final
         adjudication to the contrary, the Borrowers shall be obligated to pay
         to Lender only such interest as then shall be permitted by the laws of
         the state found to govern the contract relationship between Lender and
         the Borrowers. All interest found in excess of that rate of interest
         allowed and collected by Lender shall be applied to the 

                                       11
<PAGE>   17
         principal balance of the Loans in such manner as to prevent the payment
         and collection of interest in excess of the rate permitted by
         applicable law.

         2.4 Prepayments.

                  2.4.1 No Premiums. Except as otherwise provided in the Term
         Note, all or a portion of the principal balance(s) of the Loans may be
         prepaid at any time and from time to time without premium or penalty.

                  2.4.2 Payment of Additional Sums. All prepayments of the Loans
         pursuant to this Section shall be accompanied by the payment of any
         accrued and unpaid interest on the portion of the principal balance
         being prepaid to the date on which Lender is in receipt of Good Funds,
         and any other sums which are due and payable pursuant to the terms of
         the Loan Documents.

         2.5 Default Rate. During a Default Period that arises due to an MMI
Event of Default, the aggregate outstanding principal balance of the Term Loan
shall bear interest at the Default Rate. During a Default Period that arises due
to a HouTex Event of Default, the aggregate outstanding principal balance of the
Revolver shall bear interest at the Default Rate.

         2.6 Method of Payment; Good Funds. All payments to be made by the
Borrowers pursuant to the Loan Documents shall be delivered to Lender at 135
South LaSalle Street, Chicago, Illinois, or to such other address as Lender
shall notify the Borrowers. Payment shall not be deemed to have been received by
Lender until Lender is in receipt of Good Funds.

         2.7 Extension Right. MMI and HouTex shall each have the right (the
"Extension Right") to extend the terms of the MMI Loan and the HouTex Loan,
respectively, for one additional three month period commencing on the Maturity
Date and ending on the Extended Maturity Date, subject to the following terms,
provisions and conditions:

                  (i) MMI and/or HouTex, as applicable, shall give written
         notice (the "Extension Notice") to Lender of its or their election to
         exercise the Extension Right no later than May 31, 1997;

                  (ii) Concurrently with the delivery of an Extension Notice,
         the Borrowers shall pay to Lender a nonrefundable extension fee equal
         to $25,000 in the aggregate;

                  (iii) If MMI seeks to exercise its Extension Right, then no
         MMI Event of Default or event that with the passage of time, the giving
         of notice or both would constitute an MMI Event of Default exists as of
         the date on which such Extension Notice is delivered or on the Maturity
         Date, and if HouTex seeks to exercise its Extension Right, then no
         HouTex Event of Default or event that with the passage of time, the
         giving of notice or both would constitute a HouTex Event of Default
         exists as of the date on which such Extension Notice is delivered or on
         the Maturity Date.

         or this Loan Agreement, all of the other terms, provisions and
         conditions of the Notes and the other Loan Documents shall remain in
         full force and effect in accordance with their respective terms,
         including, without limitation, the obligation to make monthly payments
         of interest at the then applicable rate(s) of interest; and

                  (v) There shall have been no material adverse change in the
         projected income and expenses of the Individual Guarantors in the
         aggregate or either Borrower, or in any other financial information
         provided by the Individual Guarantors in the aggregate or either
         Borrower to Lender.

similar laws affecting the enforcement of creditors' rights generally and by
equitable principles.

         4.6 Business and Properties of the Borrowers.

                  4.6.1 Business Activity. Neither Borrower is engaging in any
         business or activities other than scrap metal recycling or the

         the Borrowers shall own upon Closing and any licenses and permits
         issued to the Borrowers in connection with their respective businesses
         constitute all of the Property, licenses and permits which are

         and as proposed to be conducted after the Closing.

                  4.6.2 Operating Agreements. All Operating Agreements are in
         full force and effect and no event has occurred which could result in
         the cancellation or termination of any Operating Agreement, which
         cancellation or termination could have a Material Adverse Effect.

                  4.6.3 Business Sites. There is set forth in Exhibit A the
         locations of all inventory (other than inventory that is in transit to
         customers in the ordinary course of the Borrowers' businesses),
         equipment, goods and offices presently used in the operation of the
         businesses of the Borrowers. None of such locations shall be changed
         without the prior written consent of Lender, which consent shall not be
         unreasonably withheld.

                  4.6.4 Operation and Maintenance of Equipment. To the best of
         each Borrower's knowledge, the equipment owned or to be acquired on the

made an assignment for the benefit of its creditors, (iii) has had a trustee or

hereby acknowledges 

                                       15
<PAGE>   21
that (a) the Borrowers may have incurred or may hereafter incur seller debt in
connection with the acquisition of the stock or assets of businesses related to
the business of the Borrowers, (b) the Borrowers shall be unable to service such
debt if they are unable to refinance the same prior to the maturity thereof, and
(c) the existence of such debt shall not be deemed a violation of the terms of
this Section prior to the maturity thereof or a default with respect thereto.

         4.9 Financial Statements. The Borrowers have delivered to Lender the
financial statements described on Exhibit C. To the best of each Borrower's
knowledge, said financial statements contain no material misstatements, nor are
the same based upon assumptions or facts known by such Borrower to be false or
misleading.

         4.10 Litigation. There are no actions, suits, arbitration proceedings
or claims pending or, to the best knowledge of each Borrower, threatened at law
or in equity or before any Governmental Body which, if adversely determined,
could have a Material Adverse Effect. There are no proceedings pending or, to
the best knowledge of each Borrower, threatened which call into question the
validity or enforceability of any of this Loan Agreement or the other Loan
Documents or any of the transactions contemplated hereby or thereby.

         4.11 Conflicting Agreements. Neither Borrower is in default under any
material agreement to which it is a party or by which such Borrower or any of
its Property is bound. No provision of any mortgage, indenture, contract,
agreement, statute, rule, regulation, judgment, decree or order binding on
either Borrower or affecting the business or Property of either Borrower
conflicts with or in any way would prevent the execution, delivery or
performance of the terms of any of the Loan Documents. The execution, delivery
and carrying out of the terms of the Loan Documents shall not constitute a
default under any such mortgage, indenture, contract or agreement, or result in
the creation or imposition of or obligation to create any Lien upon the Property
of either Borrower pursuant to the terms thereof.

         4.12 Taxes of Borrowers. Any charges, accruals and reserves on the
books of each Borrower with respect to all federal, state, local and other taxes
are considered by the management of such Borrower to be adequate, and neither
Borrower has knowledge of any unpaid assessment which is or might be due and
payable against such Borrower, or its business or Property, except such
assessments as are being contested in good faith and by appropriate proceedings
diligently conducted and for which adequate reserves have been set aside in
accordance with GAAP.

         4.13 Compliance with Applicable Laws. Neither Borrower is in default in
respect of any judgment, order, writ, injunction, decree or decision of any
Governmental Body. Each Borrower is in compliance in all material respects with
all applicable statutes and regulations of all Governmental Bodies.

                                       16
<PAGE>   22
conducted and as proposed to be conducted, without any known conflict with the
rights of others and, in each case, free of any Lien other than the Permitted
Liens.

         4.15 Environmental Matters. To the best knowledge of each Borrower,
except as otherwise disclosed on Exhibit D no portion of such Borrower's
Property has been used as a land fill, and there are not any known Hazardous
Materials generated, manufactured, released, stored, buried or deposited over,
beneath, in or on (or used in the construction and/or renovation of) such
Property, except in compliance with all applicable laws.

         4.16 Application of Certain Laws and Regulations.

         the sale of electricity, gas, steam, water, telephone, telegraph or

bound by any franchise, agreement, deed, lease or other instrument, which is so
unusual or burdensome, so as to cause, in the foreseeable future, a material and
adverse effect upon, or impair the financial condition, operations, business,

                                       17
<PAGE>   23
prospects or Property of such Borrower. Neither Borrower presently anticipates
that future expenditures needed to meet the provisions of federal or state
statutes, orders, rules or regulations will be so burdensome so as to have a
Material Adverse Effect on such Borrower. Notwithstanding the foregoing, Lender
hereby acknowledges that (a) the Borrowers may have incurred or may hereafter
incur seller debt in connection with the acquisition of the stock or assets of
businesses related to the business of the Borrowers, (b) the Borrowers shall be
unable to service such debt if they are unable to refinance the same prior to
the maturity thereof, and (c) the existence of such debt shall not be deemed a
violation of the terms of this Section prior to the maturity thereof or a
default with respect thereto.

         4.20 Employee Benefit Plans. Any Plan of a Borrower is in material
compliance with the applicable provisions of ERISA and the Code, and all reports
required to be filed by ERISA and the Code in respect of each such Plan have
been filed. Each Borrower has met all requirements imposed by ERISA and the Code
in respect of the funding of all Plans. No Plan which is subject to Part 3 of
Subtitle B of Title I of ERISA or Section 412 of the Code ever has incurred an
"accumulated funding deficiency" as such term is defined in Section 302 of ERISA
or Section 412(a) of the Code (whether or not waived). There has been no
non-exempt prohibited transaction (within the meaning of Section 4975 of the
Code or Part 4 of Subtitle B of Title I of ERISA) with respect to any Plan.
Since the effective date of ERISA, there have not been, and there do not now
exist, any events or conditions which would permit any Plan to be terminated
under circumstances which would cause the Lien provided under Section 4068 of
ERISA to attach to the Property of a Borrower. Since the effective date of
ERISA, no "reportable event", as defined in Title IV of ERISA, which may
constitute grounds for the termination of any Plan under Title IV of ERISA, has
occurred and no Plan has been terminated in whole or in part. No liability to
the PBGC (other than required premiums, all of which have been paid to the
extent that they were due and payable) or to any Plan has been or is expected to
be incurred by a Borrower. As of the Closing Date, the present value of all
accrued benefits under each Plan, calculated on the basis of the actuarial
assumptions specified in the most recent actuarial valuation for such Plan, will
not exceed the fair market value of the assets of such Plan allocable to such
benefits.

         4.21 Employee Matters. As of the date hereof, the employees of the
Borrowers are not subject to any collective bargaining agreement, and there are
no strikes, work stoppages or controversies pending, or to the best knowledge of
the Borrowers, threatened against either Borrower by any of its employees.

         4.22 Eligible Inventory. With respect to Eligible Inventory referred to
in any Borrowing Base Certificate, the completion and sale or other disposition
of such Inventory by a Person other than HouTex would not require the consent of
any Person or constitute a breach of any contract to which HouTex is a party or
to which the Inventory is subject.

         4.23 Eligible Accounts. With respect to Eligible Accounts referred to
in any Borrowing Base Certificate, as of the date of such Borrowing Base
Certificate: (a) the Eligible Accounts are genuine, are in all respects what
they purport to be, and are not evidenced by a judgment; (b) the Eligible
Accounts represent undisputed, bona fide transactions completed in accordance
with the 

                                       18
<PAGE>   24
terms and provisions contained in the documents delivered to Lender with respect
thereto; (c) the amounts reflected on the applicable Borrowing Base Certificate
and on HouTex's books and records and all invoices and statements which may be
delivered to Lender with respect thereto are owing solely to HouTex and are not
in any way contingent (except with respect to Accounts in connection with which
account debtors are entitled to return Inventory solely on the basis of the
quality of such Inventory); (d) no payments have been made in respect of such
Eligible Accounts or the portion thereof reflected in such Borrowing Base
Certificate; (e) there are no setoffs, counterclaims or disputes asserted or, to
the best of HouTex's knowledge, existing with respect thereto and HouTex has not
made any agreement with any account debtor for any deduction therefrom except a
discount or allowance allowed by HouTex in the ordinary course of its business
for prompt payment which has been reflected by a corresponding reduction in the
amount of the Eligible Accounts; (f) to the best of HouTex's knowledge, there
are no facts, events or occurrences which in any way impair the validity or
enforcement thereof or tend to reduce the amount payable thereunder as shown on
the respective Borrowing Base Certificate, HouTex's books and records and all
invoices and statements delivered to Lender with respect thereto; (g) to the
best of HouTex's knowledge without inquiry, all account debtors with respect to
the Eligible Accounts have the capacity to contract and are solvent; and (h) to
the best of HouTex's knowledge without inquiry, there are no proceedings or
actions which are threatened or pending against any account debtor with respect
to the Eligible Accounts which could reasonably be expected to result in any
material adverse change in such account debtor's financial condition.

         4.24 Bailment Relationships. Exhibit A lists all locations at which
HouTex stores Inventory pursuant to agreements with warehousemen, consignees or
other bailees. All such agreements are in full force and effect and, to HouTex's
knowledge, no claim has been made or default asserted against HouTex thereunder.
HouTex has paid all storage costs and other charges which are due and payable by
it under its agreements with all warehousemen, consignees and other bailees.

         4.25 Owned and Leased Property. HouTex owns no real property. The only
real property leased by HouTex is described on Exhibit A attached hereto. HouTex
has not leased or subleased any of its Property to any other Person.

5.       AFFIRMATIVE COVENANTS.  Until all of Borrowers' Obligations are paid 
and performed in full, each Borrower covenants to Lender only for itself and not
as to the other Borrower as follows:

         5.1 Legal Existence; Good Standing. Each Borrower shall maintain its
existence and shall remain in good standing (or shall have such good standing
reinstated within 15 days after the loss thereof) in its jurisdiction of
incorporation and maintain its qualification in all other jurisdictions in which
the failure to do so could have a Material Adverse Effect on such Borrower.

         5.2 Inspection of Books and Records. Each Borrower shall permit
representatives of Lender to visit its offices to examine its books and records
and Accountants' reports relating thereto, 

                                       19
<PAGE>   25
and to make copies or extracts therefrom, and to discuss its business and
affairs with its employees, all at reasonable times during normal business
hours, upon reasonable prior notice.

         5.3 Inspection of Collateral. Lender (by any of its officers, employees
and/or agents) shall have the right, during normal business hours and upon
reasonable notice to the Borrowers prior to the occurrence of an Event of
Default (and after the occurrence of an Event of Default, at any time or times)
to inspect the Collateral and all related records (and the premises upon which
it is located) and to verify the amount and condition of or any other matter
relating to the Collateral. All reasonable costs, fees and expenses incurred by
Lender in connection with all such field examinations shall constitute part of
Borrowers' Obligations, payable by the Borrowers to Lender on demand.

         5.4 Financial Statements and Other Information. Each Borrower will
maintain a system of accounting in accordance with GAAP and furnish to Lender:

                  5.4.1 Annual Statements. As soon as available and in any event
         within 90 days after the close of each fiscal year, each Borrower shall
         furnish to Lender a copy of its (a) balance sheet as of the end of such
         year, and (b) statements of income and cash flow for such year, setting
         forth in each case in comparative form the corresponding figures for
         the preceding year, all in reasonable detail, and in each case audited
         by the Accountants. Such annual statements shall be accompanied by a
         report of the Accountants which states that in preparing the financial
         statements of such Borrower, nothing came to the attention of the
         Accountants that caused them to believe that such Borrower was not in
         compliance with the terms, covenants, provisions, or conditions of any
         of the Loan Documents or that there shall have occurred a condition or
         event that constitutes an Event of Default (or, if applicable,
         specifying in such certificate the nature and status of any instances
         of non-compliance or Events of Default), and which is otherwise in a
         form reasonably satisfactory to Lender.

                  5.4.2 Monthly Statements. As soon as available and in any
         event within 15 days after the end of each month, each Borrower shall
         furnish to Lender a copy of its (a) unaudited balance sheet as of the
         end of such month, and (b) unaudited statements of income and cash flow
         for such month and for the period from the beginning of the then
         current fiscal year to the end of such month, all in reasonable detail
         and containing such information as Lender may require and certified by
         the chief financial officer of such Borrower.

                  5.4.3 Notice of Defaults; Loss. Immediate written notice of
         the following: (i) any Indebtedness of either Borrower is declared or
         becomes due and payable prior to its declared or stated maturity, or

         evidence of Indebtedness, certificate or security evidencing any such
         Indebtedness of either Borrower has the right to declare such
         Indebtedness due and payable prior to its stated maturity, (iii) there
         shall occur and be continuing a Default or Event of Default, and such
         notice shall be accompanied by a statement of the president of each
         Borrower setting forth what action the Borrowers propose to take in
         respect thereof, or (iv) any event within either 

                                       20
<PAGE>   26
         Borrower's control that causes a material loss or depreciation in the
         value of assets of such Borrower or otherwise results in a Material
         Adverse Effect.

                  5.4.4 Notice of Suits, Adverse Events. Immediate written
         notice of the following: (i) the issuance of any citation, summons,
         subpoena, order to show cause or other order naming either Borrower a

         Material Adverse Effect, together with a copy of such citation,
         summons, subpoena, order to show cause or other order, (ii) any lapse

         Governmental Body or any other Person to renew or extend any such
         material license, permit, franchise, agreement or other authorization,

         special reports filed by either Borrower with any Governmental Body or

         are requested by Lender, and copies of any material notices and other
         communications from any Governmental Body or Person which specifically

                  time.

         5.5 Reports to Governmental Bodies and Other Persons. Each Borrower
shall file, all on a timely basis, all reports, applications, documents,
instruments and information required to be filed pursuant to all rules,
regulations or requests of any Governmental Body or other Persons having

                                       21
<PAGE>   27
HouTex shall deliver to Lender the following, all of which are to be in form and

Hazardous Materials, or (ii) any notice from any Governmental Body or any other

HouTex from the operation or ownership of its business or otherwise if a HouTex
Event of Default or event or circumstance that with the passage of time, the
giving of notice or both would constitute a HouTex Event of Default then exists.

         6.3 Amendments of Agreements. Neither Borrower shall consent to any
amendment to any agreements, franchises, licenses or permits which are required
in order to conduct the businesses of such Borrower if such amendment could have
a Material Adverse Effect on such Borrower.

Plan which would result in any material liability of such Borrower to the PBGC,
(ii) permit the occurrence of any "reportable event" (as defined in Title IV of
ERISA), or any other event or condition, which presents a risk of such a
termination by the PBGC of any Plan, or (iii) withdraw or effect a partial

<PAGE>   29
         7.1 Events of Default. The occurrence of any of the following shall
constitute an "MMI Event of Default" under the Loan Documents:

         portion of its obligations under any of the Loan Documents on or before
         the date on which the same become due and payable.

                  7.1.2 Breach of Covenants.

                           (a) If MMI shall fail to observe or perform any

                           (b) If MMI shall fail to observe or perform any

                  after written notice of such failure is given by Lender.

                           (c) If MMI shall fail to observe or perform any
                  covenant or agreement (other than those referred to in
                  subparagraphs (a) and (b) above) made by MMI in any of the
                  Loan Documents; provided, however, that if such failure by its
                  nature can be cured, then MMI shall have a period of thirty
                  days after written notice from Lender of such failure to cure
                  the same and an MMI Event of Default shall not be deemed to
                  exist during such period, provided further that if MMI
                  commences to cure such failure during such period and is
                  diligently and in good faith attempting to effect such cure,
                  such period shall be extended for thirty additional days, but
                  in no event shall such period be longer than sixty days in the
                  aggregate.

                  7.1.3 Breach of Representation. Any representation or warranty
         made by MMI in or pursuant to any of the Loan Documents or in any
         instrument or document furnished in compliance with the Loan Documents
         shall prove to be false or misleading in any material respect on the
         date as of which such representation or warranty is made.

         shall be in default (as principal or guarantor or other surety) in the
         payment of any principal of or premium or interest on any Indebtedness
         for Borrowed Money (other than Borrowers' Obligations), beyond the

         of any stock or assets of or other interest in a business acquired by
         MMI), and the aggregate amount of such payments then in default beyond
         such grace period shall exceed $100,000, or (ii) if MMI at any time
         shall be in default in respect of any issue of Indebtedness for
         Borrowed Money (other than 

                                       24
<PAGE>   30

         such issue of Indebtedness for Borrowed Money, and such default shall
         continue beyond the grace period, if any, applicable thereto
         (including, without limitation, Indebtedness for Borrowed Money owing
         by MMI to the seller of any stock or assets of or other interest in a
         business acquired by MMI).

                  7.1.5 Bankruptcy.

                           (a) If MMI or any Individual Guarantor shall (i)
                  generally not be paying debts as they become due, (ii) file,
                  or consent, by answer or otherwise, to the filing against MMI
                  or Individual Guarantor, of a petition for relief or
                  reorganization or arrangement or any other petition in

                  substantial part of the Property owned by MMI or Individual
                  Guarantor, (v) be adjudicated insolvent, or (vi) take action

                  jurisdiction shall enter an order appointing a custodian,
                  receiver, trustee or other officer with similar powers with
                  respect to MMI or Individual Guarantor without MMI's or such
                  Individual Guarantor's consent, or with respect to any

or penalties thereon, and agree to hold Lender harmless with respect thereto.

and the validity and enforceability of the remaining provisions, and this Loan

provision of any of the Loan Documents shall be effective unless the same shall
be in writing, and then such waiver or consent shall be effective only in the
specific instance and for the purpose for which given. No notice to or demand on
the Borrowers in any case shall entitle them to any other or further notice or
demand in the same, similar or other circumstances.

reference only and shall not limit or otherwise affect the meaning hereof.

         10.9 Sale of Interest. Neither Borrower may sell, assign or transfer

         10.11 Remedies Cumulative. All rights and remedies of Lender pursuant
to this Loan Agreement, any other Loan Documents or otherwise, shall be
cumulative and non-exclusive, and may be exercised singularly or concurrently.
One or more successive actions may be brought against the Borrowers as often as
Lender deems advisable, until all of Borrowers' Obligations are paid and
performed in full.

         10.12 Entire Agreement. This Loan Agreement and the other Loan

or thereby and supersede any prior agreements, whether written or oral, relating
to the subject matter hereof.

FORUM BASED ON LACK OF VENUE. SHOULD A BORROWER, AFTER BEING SO SERVED, FAIL TO
APPEAR OR ANSWER TO ANY SUMMONS, COMPLAINT, PROCESS OR PAPERS SO SERVED WITHIN
THE NUMBER OF DAYS PRESCRIBED BY LAW AFTER THE MAILING THEREOF, SUCH BORROWER
SHALL BE DEEMED IN DEFAULT AND AN ORDER AND/OR JUDGMENT MAY BE ENTERED BY LENDER

                  shall equal $25,000;

                           (iii) No Event of Default or event or circumstance

                           (iv) Except as expressly provided to the contrary in
                  this Note or the Loan Agreement, all of the other terms,
                  provisions and conditions of this Note and the other Loan
                  Documents shall remain in full force and effect in accordance
                  with their respective terms, including, without limitation,
                  the obligation to make monthly payments of interest at the
                  then applicable rate(s) of interest;

                           (v) There shall have been no material adverse change
                  in the projected income and expenses of the Individual
                  Guarantors in the aggregate or Maker, or in any other material
                  financial information provided by Maker or the Individual
                  Guarantors to Lender.

                  (d) This is a revolving credit facility and any portion of the
         principal balance of this Note that is repaid may thereafter be
         reborrowed, subject to the terms and conditions set forth in the Loan
         Agreement.

         5. Application. All payments and prepayments on account of the Loan
shall be first applied to accrued and unpaid interest on the unpaid principal
balance of this Note, second, to all other sums (other than principal) then due
Lender hereunder or under any of the other Loan Documents, and third, to the
outstanding balance of the Loan.

         6. Default Rate. After maturity or the earlier acceleration of the
indebtedness evidenced by this Note, or if said indebtedness has not been
accelerated, during any period in which an Event of Default exists under this
Note, Maker shall pay interest on the balance of principal remaining unpaid
during any such period at the Default Rate then in effect under this Note. The
interest accruing under this Section shall be immediately due and payable by
Maker to the holder of this Note and shall be additional indebtedness evidenced
by this Note.

         7. Late Charge. In the event any payment of interest or principal due
hereunder is not made when such payment is due in accordance with the terms
hereof, then, in addition to the payment of the amount so due, Maker shall pay
to Lender a "late charge" of five cents for each whole dollar so overdue to
defray part of the cost of collection and handling such late payment. Maker
agrees that the damages to be sustained by the holder hereof for the detriment
caused by any late payment is extremely difficult and impractical to ascertain,
and that the amount of five cents for each one dollar due is a reasonable
estimate of such damages, does not constitute interest, and is not a penalty.

         8. Prepayment. Maker reserves the right, without cost, premium or
penalty, to prepay all or any part of the indebtedness evidenced by this Note at
any time and from time to time.

         9. Loan Documents. This Note is the "Revolver Note" referred to in the
Loan Agreement and is secured by the liens, security interest and encumbrances
created by the Loan Documents. Reference is hereby made to the Loan Documents
(which are incorporated herein by reference as fully and with the same effect as
if set forth herein at length) for a statement of the covenants and agreements
contained therein, a statement of the rights, remedies, and security afforded
thereby, and all matters therein contained.

         10. Events of Default. The occurrence of a HouTex Event of Default
under the terms of the Loan Agreement shall constitute an "Event of Default"
under this Note.

         11. Remedies. At the election of the holder hereof, and without notice,
the principal balance remaining unpaid under this Note, and all unpaid interest
accrued thereon, shall be and become immediately due and payable in full upon
the occurrence of any Event of Default. Failure to exercise this option shall
not constitute a waiver of the right to exercise same in the event of the
continuation of such Event of Default or any subsequent Event of Default. No
holder hereof shall, by any act of omission or commission, be deemed to waive
any of its rights, remedies or powers hereunder or otherwise unless such waiver
is in writing and signed by the holder hereof, and then only to the extent
specifically set forth therein. The rights, remedies and powers of the holder
hereof, as provided in this Note and in all of the other Loan Documents are
cumulative and concurrent, and may be pursued singly, successively or together
against Maker and the Individual Guarantors and any security given at any time
to secure the repayment hereof, all at the sole discretion of the holder hereof.
If any suit or action is instituted or attorneys are employed to collect this
Note or any part thereof, and Lender succeeds in obtaining any judgment or other
relief sought, Maker promises and agrees to pay all costs of collection,
including reasonable attorneys' fees and court costs.

         12. Waivers. Maker and all others who now or may at any time become
liable for all or any part of the obligations evidenced hereby, expressly agree
hereby to be jointly and severally bound and (i) waive and renounce any and all
homestead, redemption and exemption rights and the benefit of all valuation and
appraisement privileges against the indebtedness evidenced by this Note or by
any extension or renewal hereof; (ii) except for notices and demands expressly
provided for under this Note or any of the other Loan Documents, waive
presentment and demand for payment, notices of nonpayment and of dishonor,
protest of dishonor, and notice of protest; (iii) waive any and all notices in
connection with the delivery and acceptance hereof and all other notices in
connection with the performance, default, or enforcement of the payment hereof
or hereunder, except for notices and demands expressly provided for under this
Note or any of the other Loan Documents; (iv) waive any and all lack of
diligence and delays in the enforcement of the payment hereof; (v) agree that
the liability of each Maker, guarantor, endorser or obligor shall be
unconditional and without regard to the liability of any other person or entity
for the payment hereof, and shall not in any manner be affected by any
indulgence or forbearance granted or consented to by Lender to any of them with
respect hereto; (vi) consent to any and all extensions of time, renewals,
waivers, or modifications that may be granted by Lender with respect to the
payment or other provisions hereof, and to the release of any security at any
time given for the payment hereof, or any part thereof, with or without
substitution, and to the release of any person or entity liable for the payment
hereof; and (vii) consent to the addition of any and all other makers,
endorsers, guarantor, and other obligors for the payment hereof, and to the
acceptance of any and all other security for the payment hereof, and agree that
the addition of any such makers, endorsers, guarantors or other obligors, or
security shall not affect the liability of Maker, any guarantor and all others
now liable for all or any part of the obligations evidenced hereby.

         13. Business Loan. The Loan is a business loan which comes within the
purview of Section 205/4, paragraph (1)(c) of Chapter 815 of the Illinois
Compiled Statutes, as amended. 

                                       -4-
<PAGE>   5
Maker agrees that the obligation evidenced by this Note is an exempted
transaction under the Truth In Lending Act, 15 U.S.C., Section 1601, et seq.

         14. Time of the Essence. Time is of the essence hereof.

         15. Governing Law; Modification. This Note is governed and controlled
as to validity, enforcement, interpretation, construction, effect and in all
other respects by the statutes, laws and decisions of the State of Illinois.
This Note may not be changed or amended orally but only by an instrument in
writing signed by the party against whom enforcement of the change or amendment
is sought.

         16. No Partnership. Lender shall not be construed for any purpose to be
a partner, joint venturer, agent or associate of Maker or of any partner,
lessee, operator, concessionaire or licensee of Maker in the conduct of their
respective businesses, and by the execution of this Note, Maker agrees to
indemnify, defend, and hold Lender harmless from and against any and all

                  (g) Debtor shall reimburse Secured Party for all costs,
         expenses and fees, including, without limitation, court costs and

         any material adverse change in any facts or circumstances warranted or
         represented by Debtor in this Agreement or in any other writing
         furnished by Debtor to Secured Party in connection with the Collateral,
         the Obligations or the business and operation of Debtor or the
         Collateral; (vii) promptly notify Secured Party of any claim, action or
         proceeding affecting title to the Collateral, or any part thereof, or
         the security interest created herein, and, at the request of Secured

         proceeding; and (viii) promptly, after being requested by Secured
         Party, pay to Secured Party the amount of all expenses, including

         any kind or character.

                  (j) Should any part of the Collateral ever be in any manner
         converted by its issuer or maker into another type of property or any
         money or other proceeds ever be paid or delivered to Debtor as a result
         of Debtor's rights in the Collateral, then all such property, money and
         other proceeds shall become part of the Collateral, and Debtor
         covenants to forthwith pay or deliver to Secured Party all of the same
         which is susceptible of delivery and, at the same time, if Secured
         Party deems it necessary and so requests, Debtor will properly endorse
         or assign the same (provided that if no Event of Default then exists,
         Debtor shall not be required to deliver to Secured Party cash received
         in satisfaction of an account receivable, provided further that nothing
         in this clause is intended to affect or otherwise restrict the security
         interest granted to Secured Party in the proceeds of all Collateral).
         With respect to any of such property of a kind requiring any additional
         security agreement, financing statement or other writing to perfect a
         security interest therein in favor of Secured Party, Debtor will
         forthwith execute and deliver to Secured Party whatever Secured Party
         shall deem necessary or proper for such purpose.

                  (k) Should any covenant, duty or agreement of Debtor fail to
         be performed in accordance with its terms hereunder, Secured Party may,
         but shall never be obligated to, perform or attempt to perform such
         covenant, duty or agreement on behalf of Debtor, and any amount
         expended by Secured Party in such performance or attempted performance
         shall become a part of the indebtedness secured hereby, and, upon
         demand of Secured Party, Debtor agrees to pay such amount promptly to
         Secured Party, together with interest thereon at the Default Rate from
         the date of such expenditure by Secured Party until repaid to Secured
         Party.

         4. DEFAULT. An "Event of Default" shall occur under this Agreement only
upon the occurrence of (a) a breach by Debtor of any of the covenants,
agreements, representations, warranties or other provisions hereof which is not
cured or waived within the applicable grace or cure period, if any, set forth in
the Loan Agreement, or (b) a HouTex Event of Default described in the Loan
Agreement.

         5. SECURED PARTY'S RIGHTS AND REMEDIES. Secured Party shall have
available to it the following rights and remedies:

                  (a) Right to Assign. Secured Party may assign this Agreement,
         and if Secured Party does assign this Agreement, the assignee shall be
         entitled to the performance of all of Debtor's agreements and
         obligations under this Agreement, and the assignee shall be entitled to
         all the rights and remedies of Secured Party under this Agreement.
         Debtor expressly agrees that it will assert no claims or defenses it
         may have against Secured Party against the assignee except those
         available to it pursuant to this Agreement.

                  (b) Right to Discharge Debtor's Obligations. Secured Party
         may, at its option, discharge taxes, liens or security interests or
         other encumbrances at any time levied or placed on the Collateral, may
         remedy or cure any default of Debtor under the terms of any 

                                       -4-
<PAGE>   5
         lease, rental agreement, or other document which in any way pertains to
         or affects Debtor's title to or interest in any of the Collateral, may
         pay for insurance on the Collateral, and may pay for the maintenance
         and preservation of the Collateral, and Debtor agrees to reimburse
         Secured Party, on demand, for any payment made or any expense incurred
         by Secured Party, including reasonable attorneys' fees, pursuant to the
         foregoing authorization, together with interest at the Default Rate
         from the date so paid or incurred by Secured Party until repaid to
         Secured Party, which payments, expenses and interest shall be secured
         by this Agreement and by the other Loan Documents.

                  (c) Rights as Secured Creditor. Upon the occurrence of an
         Event of Default, Secured Party, in its sole and absolute discretion,
         may: (a) exercise any one or more of the rights and remedies afforded
         to secured parties under the Uniform Commercial Code in force in the
         State(s) in which the Collateral is located, together with any and all
         other rights and remedies otherwise provided and available to Secured
         Party at law or in equity; (b) enter, with process of law and without
         breach of the peace, any premises where the Collateral (or the books
         and records of Debtor related thereto) is or may be located, and
         without charge or liability to Secured Party therefor seize and remove
         the Collateral (and copies of Debtor's books and records in any way
         relating to the Collateral) from said premises and/or remain upon said
         premises and use the same (together with said books and records) for
         the purpose of collecting, preparing and liquidating the Collateral,
         all without cost to Secured Party; and (c) upon prior notice to Debtor
         as required by this Agreement, sell or otherwise dispose of the
         Collateral at public or private sale or auction for cash or credit
         (which sale or auction may, at the option of Secured Party, occur on
         the premises where the Collateral is located or elsewhere, at no cost
         to Secured Party) and from the proceeds of such sale or disposal retain
         (i) all costs and charges incurred by Secured Party in taking and
         causing the removal and sale or disposal of the Collateral, including
         reasonable attorneys' fees; and (ii) an amount equal to all other
         Obligations; provided, however, that Debtor shall be credited with the
         net proceeds of such sale only when such proceeds are actually received
         by Secured Party.

                  (d) Assembly of Collateral; Injunctive Relief. Upon the
         occurrence of an Event of Default, Debtor, immediately upon demand by
         Secured Party, shall assemble the Collateral and make it available to
         Secured Party at a place or places to be designated by Secured Party at
         Debtor's primary place of business or other reasonable locations within
         Texas. Debtor hereby acknowledges and agrees that if Debtor fails to
         perform, observe or discharge any of its obligations or liabilities
         under this Agreement, no remedy of law shall provide adequate relief to
         Secured Party, and that Secured Party shall be entitled to temporary
         and permanent injunctive relief in any such case without the necessity
         of proving actual damages or the posting of bond, surety or other
         security.

                  (e) Notice of Collateral Disposition. Any notice required to
         be given by Secured Party of a sale, lease or other disposition of the
         Collateral or any other intended action by Secured Party, sent by
         registered or certified United States mail, postage prepaid 

                                       -5-
<PAGE>   6
         and duly addressed to Debtor at Debtor's address set forth in the Loan
         Agreement not less than ten days prior to such proposed action, shall
         constitute commercially reasonable and fair notice to Debtor thereof.

                  (f) Matters Regarding Sale of Collateral. Debtor agrees that
         Secured Party may, if Secured Party deems it reasonable, postpone or
         adjourn any sale of Collateral from time to time by an announcement at
         the time and place of sale or by announcement at the time and place of
         such postponed or adjourned sale, without being required to give a new
         notice of sale. Debtor also waives and releases any right of Debtor to
         redeem the Collateral from such sale. At any sale or sales made
         pursuant to this Agreement or in a suit to foreclose the same, the
         Collateral, at the option of Secured Party or its assigns, may be sold
         in its entirety or separately, at the same or at different times, and
         the Collateral need not be present at the time or place of sale. At any
         such sale, Secured Party or the holder of the indebtedness hereby
         secured may bid for and purchase any of the property sold,
         notwithstanding that such sale is conducted by Secured Party or its
         attorneys, agents, or assigns, and no irregularity in the manner of
         sale or of giving notice shall operate to preclude Secured Party from
         recovering the Obligations.

                  (g) Replevin. If Secured Party seeks possession of the
         Collateral through replevin or other court action, Debtor hereby
         irrevocably waives (i) any bond, surety or security required as an
         incident to such possession, and (ii) any demand by Secured Party for
         possession of the Collateral prior to the commencement of any such suit
         or action.

                  (h) Enforcement Standards. Secured Party shall have the right
         at all times to enforce the provisions of this Agreement in strict
         accordance with the terms hereof, notwithstanding any conduct or custom
         on the part of Secured Party in refraining from so doing at any time or
         times. The failure of Secured Party at any time or times to enforce its
         rights under said provisions strictly in accordance with the same shall
         not be construed or operate as a waiver of any of the rights and
         remedies granted Secured Party hereunder or as having created a custom
         in any way or manner contrary to the specific provisions of this
         Agreement or as having in any way or manner modified the same. All
         rights and remedies of Secured Party are cumulative and concurrent, and
         the exercise of one right or remedy by Secured Party shall not be
         deemed a waiver or release of any other right or remedy.

         6. REPRESENTATIONS AND WARRANTIES. Debtor represents and warrants that:

                  (a)  Debtor has authority to execute and deliver this 
         Agreement;

                  (b)  no financing statement covering the Collateral, or any 
         part thereof, has been filed and remains in effect;

<PAGE>   7
                  (c) no other security agreement covering the Collateral, or
         any part thereof, has been made and no security interest, other than
         the one herein created, has attached or been perfected in the
         Collateral or in any part thereof;

                  (d) no material dispute, right of setoff, counterclaim or 
         defense exists with respect to any part of the Collateral;

                  (e) all information supplied and statements made in any
         financial or credit statements or application for credit prior to the
         execution of this Agreement are true and correct in all material
         respects as of the date hereof;

                  (f) at the time Secured Party's security interest attaches to
         any of the Collateral or its proceeds, Debtor will be the lawful owner
         with the right to transfer any interest therein, and Debtor will make
         such further assurances as to prove Secured Party's security interest
         in the Collateral as may be required and will defend the Collateral and
         its proceeds against the lawful claims and demands of all persons
         whomsoever.

                  (g) There is listed on EXHIBIT A hereto the location of the
         principal place of business of Debtor, all of the other places of
         business of Debtor and all locations where all tangible Collateral and

         location of (i) its places of business or its books and records, or
         (ii) any tangible Collateral, without in each case providing not less
         than thirty days prior written notice thereof to Secured Party.

                  (h) All trade or assumed names under which Debtor is doing
         business or proposes to do business are listed on EXHIBIT B. Debtor
         shall give Secured Party not less than thirty days prior written notice
         of any change in Debtor's name or any new or change in any trade name
         that Debtor uses in its business.

The delivery at any time by Debtor to Secured Party of the Collateral shall
constitute a representation and warranty by Debtor that, with respect to such
Collateral, and each item thereof, Debtor is owner of the Collateral and the
matters heretofore represented and warranted in this Paragraph 6 are true and
correct. Further, Debtor, upon the request of Secured Party, agrees to amend
this Agreement and any and all financing statements filed in connection
therewith for the purpose of setting forth in said Agreement and said financing
statements an accurate and itemized list of the Collateral now generally
described herein and in said financing statements and to include in said
accurate and itemized list an identification of the Collateral by make, model,
serial number and other appropriate descriptive data.

         7. SUBROGATION. If the Obligations, or any part thereof, are renewed or
extended, or applied toward the payment of any indebtedness secured by any
mortgage, pledge, security agreement or other lien, Secured Party shall be and
is hereby subrogated to all of the rights, titles, security interests and other
liens securing the indebtedness so renewed, extended or paid.

         8.       FURTHER AGREEMENTS.

                  (a) "Debtor" and "Secured Party" as used in this Agreement
         include the legal representatives, successors and assigns of those
         parties.

                  (b) Neither Debtor nor Secured Party shall be bound by any
         amendment not expressed in writing and signed by the party to be bound
         thereby.

                  (c) It is expressly intended, understood and agreed: (i) that
         this Agreement is made and entered into for the sole protection and
         benefit of Secured Party and Debtor, and their successors and assigns
         and no other person or persons shall have any right of action hereunder
         or rights to the proceeds of the Line of Credit at any time; (ii) that
         the proceeds of the Line of Credit do not constitute a trust fund for
         the benefit of any third party; and (iii) that no third party shall
         under any circumstances be entitled to any equitable lien on any
         undisbursed proceeds of the Line of Credit at any time. The
         relationship between Secured Party and Debtor is solely that of a
         lender and borrower, and nothing contained herein, or in the Note or

                           (iv) Except as expressly provided to the contrary in
                  this Note or the Loan Agreement, all of the other terms,
                  provisions and conditions of this Note and the other Loan
                  Documents shall remain in full force and effect in accordance
                  with their respective terms, including, without limitation,
                  the obligation to make monthly payments of interest at the

                  in the projected income and expenses of the Individual

                  financial information provided by Maker or the Individual
                  Guarantors to Lender.

         reborrowed.

                  (e) All payments and prepayments of the principal balance of
         this Note shall be applied first toward the Floating Loan, if
         applicable. If such payments or prepayments are in excess of the
         outstanding principal balance of the Floating Loan then, at Maker's
         option, either (i) such excess shall be applied against one or more
         LIBOR Loans, if applicable (such application to be made first against
         those LIBOR Loans with the earliest Interest Period expiration dates),
         in which event Maker shall pay, concurrently with the repayment of such
         LIBOR Loans, all of Lender's damages, costs and expenses (including
         prepayment premiums) arising in connection with the repayment of such
         LIBOR Loans (as more fully described below); or (ii) if applicable,
         Lender shall hold such excess (with interest being payable by Lender to
         Maker on the amount so held at the Commercial Paper Rate in effect on
         the date of such prepayment) until the next following expiration
         date(s) of existing Interest Period(s), at which time Lender shall
         apply such excess (plus interest accrued thereon as aforesaid) toward
         repayment of the LIBOR Loans to which such expiring Interest Period(s)
         apply until all of such excess is so applied. If the option described
         in clause (ii) above is selected, interest at the applicable Loan Rates
         shall continue to accrue and be payable to Lender on the entire
         outstanding principal balance of this Note (including those portions
         which will be repaid by such excess amount at the expiration of the
         applicable Interest Periods).

         5.       Conversion to or Continuation of LIBOR Loan.

                  (a) Notwithstanding anything to the contrary set forth above,
         but subject to the provisions of Sections 6 and 7 below, Maker shall
         have the option (i) to convert at any time the interest rate charged on
         all or any part of the Floating Loan (in excess of the minimum amount
         set forth below) from the Floating Rate to a Fixed Rate; and (ii) upon
         the expiration of any Interest Period applicable to a LIBOR Loan, to
         continue all or any portion of the same as a LIBOR Loan, and the
         succeeding Interest Period of such continued LIBOR Loan shall commence
         on the expiration date of the Interest Period applicable thereto,
         provided that no portion of the principal balance of the Loan may be
         continued as, or be converted into, a LIBOR Loan when any Event of
         Default has occurred and is continuing. Any partial 

                                       -4-
<PAGE>   5
         conversion to or continuation of a LIBOR Loan under this Section shall
         be in a minimum amount of $1,000,000. At the end of any Interest Period
         with respect to any LIBOR Loan, the portion of the principal balance
         constituting such LIBOR Loan shall automatically become part of the
         Floating Loan unless Maker has properly exercised an option to continue
         such LIBOR Loan as provided herein.

                  (b) If Maker desires to convert all or a portion of the
         Floating Loan to a LIBOR Loan or to continue all or any portion of a
         LIBOR Loan as the same, Maker shall notify Lender no later than 10:00
         a.m. (Chicago time) on the third Business Day prior to the proposed
         conversion or continuation date. Each notice shall specify (i) the
         proposed conversion or continuation date (which shall be a Business
         Day), (ii) the portion of the principal amount of the Floating Loan to
         be converted to or continued as a LIBOR Loan, and (iii) the requested
         Interest Period.

                  (c) Any notice for conversion to a LIBOR Loan, or continuation
         of a LIBOR Loan, shall be irrevocable and Maker shall be bound to
         convert or continue the LIBOR Loan in accordance therewith.

         6. Interest Periods. By giving notice as required under this Note,
Maker shall have the option, subject to the other provisions of this Section ,
to specify an interest period of 30, 60, or 90 days (each an "Interest Period")
during which all or a portion of the Loan shall bear interest at the applicable
Fixed Rate. The determination of Interest Periods shall be subject to the
following provisions:

                  (a) In the case of immediately successive Interest Periods
         with respect to a continued LIBOR Loan, each successive Interest Period
         shall commence on the day on which the immediately preceding Interest
         Period expires;

                  (b) If any Interest Period would otherwise expire on a day
         which is not a Business Day, the Interest Period shall be extended to
         expire on the next succeeding Business Day (unless the next succeeding
         Business Day is in the next calendar month, in which event the Interest
         Period shall expire on the immediately preceding Business Day);

                  (c) Maker may not select an Interest Period which terminates
         later than the Maturity Date (or the Extended Maturity Date, if the
         Extension Right has been timely and properly exercised prior to the
         selection of the Interest Period); and

                  (d) There shall be no more than two separate Interest Periods
         (and, therefore, no more than two separate LIBOR Loans) in effect at
         any one time.

         7.       Special Provisions Governing LIBOR Loans.

                  (a) If Maker has elected to convert to or continue a LIBOR
         Loan, then, as soon as practicable on the Interest Rate Determination
         Date applicable to such LIBOR Loan, 

                                       -5-
<PAGE>   6
         Lender shall determine (which determination shall conclusively be
         deemed to be correct absent manifest error) the Fixed Rate which shall
         apply to the requested LIBOR Loan and shall promptly give notice
         thereof to Maker. If on any Interest Rate Determination Date Lender is
         unable to obtain the applicable LIBOR Rate quotations, Lender shall
         give Maker prompt notice thereof and the LIBOR Loan requested shall
         continue to bear interest (or, in the case of a requested continuation
         of a LIBOR Loan, shall commence bearing interest at the end of the then
         current Interest Period therefor) at the Floating Rate.

                  (b) If, with respect to any Interest Period, (i) any change
         occurs in any applicable law or governmental rule, regulation or order
         (or any interpretation thereof and including the introduction of any
         new law or governmental rule, legislation or order) affecting the
         London interbank Eurodollar market for such Interest Period or (ii)
         other circumstances affecting the London interbank Eurodollar market
         for such Interest Period results in the then applicable Fixed Rates not
         adequately reflecting the cost to Lender of making, funding or
         maintaining the LIBOR Loans, Lender may, at its election, give notice
         thereof to Maker, whereupon until Lender has determined that the
         circumstances giving rise to such inadequacy no longer exist, (A) the
         right of Maker to elect to have any portion of the Loan bear interest
         at the Fixed Rate shall be suspended for such Interest Period, and (B)
         each outstanding LIBOR Loan shall bear interest at the Floating Rate
         commencing on the last day of the then current Interest Period
         therefor, notwithstanding any prior election by Maker to the contrary.

         8. Illegality. If Lender shall have reasonably determined that the
making or continuation of any LIBOR Loan has become prohibited or otherwise
unlawful under any law, governmental rule, regulation or order of any
governmental body, then Lender shall promptly give notice to Maker of such
determination. Upon delivery of such notice, Maker's right to request Lender to
make LIBOR Loans shall be immediately suspended to the extent unlawful, as
specified in such notice, and if any LIBOR Loans are then outstanding, each such
LIBOR Loan shall, if required by law, immediately commence bearing interest at
the Floating Rate in lieu of the applicable Fixed Rate. If Lender determines at
any time following delivery of the aforementioned notice that Lender may
lawfully make LIBOR Loans of the type referred to in such notice, Lender shall
promptly give notice to Maker of such determination, whereupon Maker's right to
request LIBOR Loans of such type shall be restored.

         9.       Reimbursement for Losses and Expenses; Increased Capital.

                  (a) Maker shall compensate Lender, within three Business Days
         following Maker's receipt of the written statement described below, for
         all actual losses, expenses and liabilities (including, without
         limitation, any loss or expense incurred by reason of liquidation or
         reemployment of deposits or other funds acquired by Lender to fund or
         maintain the LIBOR Loans to Maker) that Lender may sustain in
         connection with the funding or maintenance of LIBOR Loans (except to
         the extent resulting from Lender's negligent or intentional error),
         including, without limitation, expenses and liabilities incurred (i) if
         such LIBOR Loans are not made when requested, (ii) if any prepayment of


                                       -6-
<PAGE>   7
         any LIBOR Loan occurs for any reason on a date that is not the last day
         of the applicable Interest Period, or (iii) as a consequence of any
         required conversion of the interest rate applicable to a LIBOR Loan to
         a Floating Rate in the circumstances described in this Note. Lender
         shall deliver to Maker a written statement of such losses, expenses and
         liabilities promptly after the same have been determined (including the
         reason therefor and the calculation thereof), and such statement shall
         conclusively be deemed to be correct absent manifest error.

                  (b) If either (i) the introduction of or any change in (or a
         change in the authoritative interpretation of) any law or regulation
         regarding capital adequacy or (ii) compliance by Lender with any
         guideline from any central bank or other governmental body regarding
         capital adequacy (whether or not having the force of law and whether or
         not the failure to comply therewith would be unlawful) has the effect
         of reducing the rate of return on Lender's capital as a consequence of
         its obligations hereunder to fund or maintain LIBOR Loans to a level
         below that which Lender would have achieved but for such introduction,
         change or compliance, then, upon demand by Lender, Maker shall, within
         three Business Days following Maker's receipt of the statement
         described below, pay to Lender additional amounts sufficient to
         compensate Lender for such reduction. Lender shall deliver to Maker a
         written statement of such amounts promptly after the same have been
         determined, and such statement shall conclusively be deemed to be
         correct absent manifest error.

         10.      LIBOR Rate Taxes.  Maker agrees that:

                  (a) Maker shall pay, prior to the date on which penalties
         attach thereto, all present and future stamp and other taxes, levies,
         or costs and charges whatsoever imposed, assessed, levied or collected
         on or in respect of the Loan as a result of the interest rate being
         determined by reference to the LIBOR Rate or any payments of principal,
         interest or other amounts made on or in respect of a LIBOR Loan (all
         such taxes, levies, costs and charges being herein collectively called
         "LIBOR Rate Taxes"); provided, however, that LIBOR Rate Taxes shall not
         include income or franchise taxes imposed by any jurisdic tion (except
         that Maker shall be liable for the payment of the amount of any
         additional net income or franchise taxes actually incurred by Lender 
         and directly attributable to payments made by Maker pursuant to this 
         Section ).

                  (b) Maker shall indemnify Lender against, and reimburse Lender
         within five Business Days after demand for, any LIBOR Rate Taxes paid
         by Lender.

         11. Application. Subject to the provisions of Section 4 above, all
payments and prepayments on account of the Loan shall be first applied to
accrued and unpaid interest on the unpaid principal balance of this Note,
second, to all other sums (other than principal) then due Lender hereunder or
under any of the other Loan Documents, third, to the outstanding balance of the
Floating Loan, and the remainder, if any, to the outstanding balances of the
LIBOR Loans in such manner and order as Lender determines.

         12. Default Rate. After maturity or the earlier acceleration of the
indebtedness evidenced by this Note, or if said indebtedness has not been
accelerated, during any period in which an Event of Default exists under this
Note, Maker shall pay interest on the balance of principal remaining unpaid
during any such period at the Default Rate then in effect under this Note. The
interest accruing under this Section shall be immediately due and payable by
Maker to the holder of this Note and shall be additional indebtedness evidenced
by this Note.

         13. Late Charge. In the event any payment of interest or principal due
hereunder is not made when such payment is due in accordance with the terms
hereof, then, in addition to the payment of the amount so due, Maker shall pay
to Lender a "late charge" of five cents for each whole dollar so overdue to
defray part of the cost of collection and handling such late payment. Maker
agrees that the damages to be sustained by the holder hereof for the detriment
caused by any late payment is extremely difficult and impractical to ascertain,
and that the amount of five cents for each one dollar due is a reasonable
estimate of such damages, does not constitute interest, and is not a penalty.

         14. Prepayment. Maker reserves the right, without cost, premium or
penalty (except as provided in Sections 4 and 9 above), to prepay all or any
part of the indebtedness evidenced by this Note at any time and from time to
time.

         15. Loan Documents. This Note is the "Term Note" referred to in the
Loan Agreement and is secured by the liens, security interest and encumbrances
created by the Loan Documents. Reference is hereby made to the Loan Documents
(which are incorporated herein by reference as fully and with the same effect as
if set forth herein at length) for a statement of the covenants and agreements
contained therein, a statement of the rights, remedies, and security afforded
thereby, and all matters therein contained.

         16. Events of Default. The occurrence of an MMI Event of Default under
the terms of the Loan Agreement shall constitute an "Event of Default" under
this Note.

         17. Remedies. At the election of the holder hereof, and without notice,
the principal balance remaining unpaid under this Note, and all unpaid interest
accrued thereon, shall be and become immediately due and payable in full upon
the occurrence of any Event of Default. Failure to exercise this option shall
not constitute a waiver of the right to exercise same in the event of the
continuation of such Event of Default or any subsequent Event of Default. No
holder hereof shall, by any act of omission or commission, be deemed to waive
any of its rights, remedies or powers hereunder or otherwise unless such waiver
is in writing and signed by the holder hereof, and then only to the extent
specifically set forth therein. The rights, remedies and powers of the holder
hereof, as provided in this Note and in all of the other Loan Documents are
cumulative and concurrent, and may be pursued singly, successively or together
against Maker and the Individual Guarantors and any security given at any time
to secure the repayment hereof, all at the sole discretion of the holder hereof.
If any suit or action is instituted or attorneys are employed to collect this
Note or any part thereof, and Lender succeeds in obtaining any judgment or other
relief 

                                       -8-
<PAGE>   9
sought, Maker promises and agrees to pay all costs of collection, including
reasonable attorneys' fees and court costs.

         18. Waivers. Maker and all others who now or may at any time become
liable for all or any part of the obligations evidenced hereby, expressly agree
hereby to be jointly and severally bound and (i) waive and renounce any and all
homestead, redemption and exemption rights and the benefit of all valuation and
appraisement privileges against the indebtedness evidenced by this Note or by
any extension or renewal hereof; (ii) except for notices and demands expressly
provided for under this Note or any of the other Loan Documents, waive
presentment and demand for payment, notices of nonpayment and of dishonor,
protest of dishonor, and notice of protest; (iii) waive any and all notices in
connection with the delivery and acceptance hereof and all other notices in
connection with the performance, default, or enforcement of the payment hereof
or hereunder, except for notices and demands expressly provided for under this
Note or any of the other Loan Documents; (iv) waive any and all lack of
diligence and delays in the enforcement of the payment hereof; (v) agree that
the liability of each Maker, guarantor, endorser or obligor shall be
unconditional and without regard to the liability of any other person or entity
for the payment hereof, and shall not in any manner be affected by any
indulgence or forbearance granted or consented to by Lender to any of them with
respect hereto; (vi) consent to any and all extensions of time, renewals,
waivers, or modifications that may be granted by Lender with respect to the
payment or other provisions hereof, and to the release of any security at any
time given for the payment hereof, or any part thereof, with or without
substitution, and to the release of any person or entity liable for the payment
hereof; and (vii) consent to the addition of any and all other makers,
endorsers, guarantor, and other obligors for the payment hereof, and to the
acceptance of any and all other security for the payment hereof, and agree that
the addition of any such makers, endorsers, guarantors or other obligors, or
security shall not affect the liability of Maker, any guarantor and all others
now liable for all or any part of the obligations evidenced hereby.

         19. Business Loan. The Loan is a business loan which comes within the
purview of Section 205/4, paragraph (1)(c) of Chapter 815 of the Illinois
Compiled Statutes, as amended.  agrees that the obligation evidenced by this 
Note is an exempted transaction under the Truth In Lending Act, 15 U.S.C.,
Section 1601, et seq.

         20. Time of the Essence.  Time is of the essence hereof.

         21. Governing Law; Modification. This Note is governed and controlled
as to validity, enforcement, interpretation, construction, effect and in all
other respects by the statutes, laws and decisions of the State of Illinois.
This Note may not be changed or amended orally but only by an instrument in
writing signed by the party against whom enforcement of the change or amendment
is sought.

         22. No Partnership. Lender shall not be construed for any purpose to be
a partner, joint venturer, agent or associate of Maker or of any partner,
lessee, operator, concessionaire or licensee of Maker in the conduct of their
respective businesses, and by the execution of this Note, Maker agrees to
indemnify, defend, and hold Lender harmless from and against any and all
damages, costs, 

                                       -9-
<PAGE>   10
expenses and liability that may be incurred by Lender as a
result of a claim that Lender is such partner, joint venturer, agent or

NOTE OR ANY OF THE OTHER LOAN DOCUMENTS SHALL BE LITIGATED IN THE CIRCUIT COURT
OF COOK COUNTY, ILLINOIS, OR THE UNITED STATES DISTRICT COURT FOR THE NORTHERN
DISTRICT OF ILLINOIS OR, IF LENDER INITIATES SUCH ACTION, ANY COURT IN WHICH
LENDER SHALL INITIATE SUCH ACTION AND WHICH HAS JURISDICTION. MAKER HEREBY

                                      -10-
<PAGE>   11
EXPRESSLY SUBMITS AND CONSENTS IN ADVANCE TO SUCH JURISDICTION IN ANY ACTION OR
PROCEEDING COMMENCED BY LENDER IN ANY OF SUCH COURTS, AND HEREBY WAIVES PERSONAL
SERVICE OF THE SUMMONS AND COMPLAINT, OR OTHER PROCESS OR PAPERS ISSUED THEREIN,
AND AGREES THAT SERVICE OF SUCH SUMMONS AND COMPLAINT OR OTHER PROCESS OR PAPERS

WOULD BE BASED UPON DIFFICULT AND COMPLEX ISSUES AND THEREFORE, THE PARTIES
AGREE THAT ANY COURT PROCEEDING ARISING OUT OF ANY SUCH CONTROVERSY WILL BE
TRIED IN A COURT OF COMPETENT JURISDICTION BY A JUDGE SITTING WITHOUT A JURY.

         IN WITNESS WHEREOF, Maker has executed this Note as of the day and year
first written above.

                             SUBORDINATION AGREEMENT

         This Subordination Agreement (this "AGREEMENT") is made as of January
7, 1997, by and between METAL MANAGEMENT, INC., a Delaware corporation (the
"UNDERSIGNED"), and LASALLE NATIONAL BANK, a national banking association
("LENDER").

                                R E C I T A L S:

         (A) The Undersigned desires for the Lender to extend credit to HouTex
Metals Company, Inc., a Texas corporation ("BORROWER"), pursuant to that certain
Loan Agreement, dated as of January 7, 1997, among the Lender, Borrower and the
Undersigned (the "Loan Agreement").

         (B) The Undersigned desires to extend credit to Borrower pursuant to a
certain Revolving Credit Note dated January 7, 1997, in the initial principal
amount of $1,000,000 (the "Note").

         (C) Lender has conditioned its obligations to lend pursuant to the
Notes referred to in paragraph (A) above, and its agreement to and approval of
the extension of credit referred to in paragraph (B) above, as well as any
continuations thereof, on the Undersigned's agreeing to subordinate its right to
receive payment on any present and future indebtedness due the Undersigned from
Borrower in the manner described in this Agreement.

         (D) The Undersigned owns one hundred percent (100%) of the issued and
outstanding capital stock of Borrower and the extension of credit, and any
continuation thereof, by the Undersigned to Borrower is necessary to the conduct
and operation of the business of Borrower, and will inure to the financial
benefit of the Undersigned.

         NOW, THEREFORE, in consideration of the agreement by the Lender to
allow the Undersigned to extend credit to Borrower pursuant to the Note, and for
other good and valuable consideration to the Undersigned, the receipt and
sufficiency of which is hereby acknowledged, the Undersigned hereby:

         (a) subordinates the indebtedness described above, as well as any other
indebtedness now or at any time or times hereafter owing by Borrower to the
Undersigned, whether such indebtedness is absolute or contingent, direct or
indirect and howsoever evidenced, including all interest thereon (collectively,
the "UNDERSIGNED'S CLAIMS"), to any and all debts, demands, claims, liabilities
or causes of action for which Borrower may now or at any time or times hereafter
in any way be liable to Lender under any agreement, instrument or document
executed and delivered or made by Borrower to Lender (collectively, the "LENDER
LOANS");

         (b) subordinates all security interests, liens, encumbrances and claims
which in any way secure the payment of the Undersigned's Claim (collectively,
the "UNDERSIGNED'S LIENS") to all security interests, liens, encumbrances and
claims which in any way secure the payment of the Lender Loans (collectively,
the "LENDER LIENS");
<PAGE>   2
         (c) after an occurrence and during the continuation of a "Houtex Event
of Default" under the Loan Agreement, agrees to instruct Borrower not to pay,
and the Undersigned agrees not to accept payment of, or assert or seek to
enforce against Borrower, the Undersigned's Claims unless and until Lender has,
in writing, notified the Undersigned that the Lender Loans have been paid in
full, or such HouTex Event of Default has been waived or cured;

         (d) subrogates Lender to the Undersigned's Claims and the Undersigned's
Liens and assigns and agrees to endorse, deliver and deposit with Lender all
agreements, instruments and documents evidencing the Undersigned's Claims and
the Undersigned's Liens;

         (e) agrees that in the event of any liquidation, dissolution or winding
up of Borrower, or of any execution, sale, receivership, insolvency, bankruptcy,
liquidation, readjustment, reorganization, or other similar proceeding relating
to Borrower or its property, all principal and interest owing on the Lender
Loans shall first be paid in full in cash before any payment is made upon the
Undersigned's Claims;

         (f) agrees to turn over to Lender any sum or sums at any time paid to,
or received by, the Undersigned, in violation of the terms of this Agreement and
to reimburse Lender for all costs, including reasonable attorneys' fees,
incurred by Lender in the course of collecting said sum or sums should the
Undersigned fail to voluntarily turn over same to Lender; and

         (g) agrees that the Undersigned shall not take or enjoy any additional
collateral to secure the Undersigned's Claims without obtaining Lender's prior
written consent.

         The Undersigned represents and warrants to Lender that, except as
provided herein, the Undersigned has not assigned or transferred the
Undersigned's Claims or the Undersigned's Liens, or any interest therein, to any
person, firm, association, corporation or party, that the Undersigned will make
no such assignment or transfer thereof and that all agreements, instruments and
documents evidencing the Undersigned's Claims and the Undersigned's Liens will
be endorsed with proper notice of this Agreement.

         TO INDUCE LENDER TO MAKE FINANCIAL ACCOMMODATIONS TO BORROWER, THE
UNDERSIGNED IRREVOCABLY AGREES THAT ALL ACTIONS ARISING DIRECTLY OR INDIRECTLY
AS A RESULT OR IN CONSEQUENCE OF THIS AGREEMENT SHALL BE INSTITUTED AND
LITIGATED ONLY IN COURTS HAVING SITUS IN THE CITY OF CHICAGO, ILLINOIS, AND THE
UNDERSIGNED HEREBY CONSENTS TO THE EXCLUSIVE JURISDICTION AND VENUE OF ANY STATE
OR FEDERAL COURT LOCATED AND HAVING ITS SITUS IN SAID CITY, AND WAIVES ANY
OBJECTION BASED ON FORUM NON CONVENIENS, AND THE UNDERSIGNED HEREBY WAIVES
PERSONAL SERVICE OF ANY AND ALL PROCESS, AND CONSENTS THAT ALL SUCH SERVICE OF
PROCESS MAY BE MADE BY CERTIFIED MAIL, RETURN RECEIPT REQUESTED, DIRECTED TO THE
UNDERSIGNED AT THE ADDRESS INDICATED BELOW THE UNDERSIGNED'S SIGNATURE ON THE
SIGNATURE PAGE HEREOF IN THE 

                                       -2-
<PAGE>   3
MANNER PROVIDED BY APPLICABLE STATUTE, LAW, RULE OF COURT, OR OTHERWISE.

         THE UNDERSIGNED WAIVES EVERY DEFENSE, CAUSE OF ACTION, COUNTERCLAIM OR
SETOFF, WHICH THE UNDERSIGNED NOW OR HEREAFTER MAY HAVE TO ANY ACTION BY LENDER
IN ENFORCING THIS AGREEMENT AND RATIFIES AND CONFIRMS WHATEVER LENDER MAY DO
PURSUANT TO THE TERMS HEREOF AND AGREES THAT LENDER SHALL NOT BE LIABLE FOR ANY
ERRORS OF JUDGMENT OR MISTAKE OF FACT OR LAW EXCEPT FOR THOSE ERRORS OR MISTAKES
ARISING EXCLUSIVELY FROM LENDER'S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. THE
UNDERSIGNED KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVES IRREVOCABLY, THE
RIGHT IT MAY HAVE TO TRIAL BY JURY WITH RESPECT TO ANY LEGAL PROCEEDING BASED
HEREON, OR ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT AND ANY
AGREEMENT CONTEMPLATED TO BE EXECUTED IN CONJUNCTION HEREWITH OR ANY COURSE OF
CONDUCT OR DEALING IN WHICH LENDER AND THE UNDERSIGNED ARE ADVERSE PARTIES. THIS
PROVISION IS A MATERIAL INDUCEMENT FOR LENDER TO MAKE THE LENDER LOANS.

         This Agreement shall constitute a continuing agreement of
subordination, and Lender may continue, without notice to the Undersigned, to
lend monies, extend credit and make other accommodations to or for the account
of Borrower on the faith hereof until written notice of revocation of this
Agreement shall be delivered to Lender by the Undersigned. Any such notice of
revocation shall not affect this Agreement in relation to any obligations or
liabilities of Borrower then existing or created thereafter pursuant to any
previous commitment of Lender or Undersigned to Borrower, or any extensions or
renewals of any such commitment, obligations or liabilities, and as to all such
obligations and liabilities and extensions or renewals thereof, this Agreement
shall continue effective until the same shall have been fully discharged with
interest.

         The Undersigned consents and agrees that all obligations and
liabilities of Borrower to Lender shall be deemed to have been made or incurred
at the request of the Undersigned and in reliance upon this Agreement.

         No waiver shall be deemed to be made by Lender of any of its rights
hereunder unless the same shall be in writing signed by Lender and each such
waiver, if any, shall be a waiver only with respect to the specific matter or
matters to which the waiver relates and shall in no way impair the rights of
Lender or the obligations of the Undersigned to Lender in any other respect at
any other time.

         This Agreement shall be continuing, irrevocable and binding on the
Undersigned and on its heirs, successors and assigns, including a
debtor-in-possession on behalf of the Undersigned and shall inure to the benefit
of Lender, its successors and assigns.

                              REVOLVING CREDIT NOTE



$1,000,000.00                                       Date: as of January 7, 1997
Chicago, Illinois                                   Due:  June 30, 1997


         On or before the Maturity Date, HouTex Metals Company, Inc., a Texas
corporation ("Borrower"), whose address is 21 Japhet Street, Houston, Texas
77020, for value received, promises to pay to the order of Metal Management,
Inc., a Delaware corporation (hereinafter, together with any holder hereof,
called "Lender"), whose address is 500 North Dearborn, Suite 405, Chicago,
Illinois 60610, the principal sum of ONE MILLION AND NO/100 DOLLARS
($1,000,000.00) or if less, the aggregate unpaid principal amount of all
Advances under this Revolving Credit Note (this "Note") made available to
Borrower by Lender pursuant hereto. The unpaid principal amount hereof shall
bear interest at the rate of the Prime Rate plus one percent (1.0%) per annum;
provided, however, that after the occurrence and during the continuance of an
Event of Default, the unpaid principal amount hereof shall bear interest at the
rate of the Prime Rate plus four percent (4.0%) per annum.

         This Note evidences a revolving loan (the "Loan") which shall be made
available to Borrower by Lender from time to time on and after the date hereof
through the day immediately preceding the Maturity Date in the maximum principal
amount outstanding at any one time equal to $1,000,000.00 from the date hereof
through the day immediately preceding the Maturity Date. Borrower may reborrow
all or any portion of the Loan that is repaid or prepaid. This Loan may be
prepaid or repaid in whole or in part at any time without premium or penalty.
The "Maturity Date" means the earliest of: (i) June 30, 1997 (or September 30,
1997, if the "Extended Maturity Date" is in effect under the "Loan Agreement"
defined below); (ii) the date on which the Maximum Revolving Loan Amount under
the Loan Agreement is increased to or exceeding $5,500,000.00; or (iii) the date
ninety (90) days after Metal Management, Inc. ceases to own all of the issued
and outstanding capital stock of Borrower.

         Each request for an Advance hereunder shall be irrevocable and shall be
made by Borrower in writing or by telephone. If a request for an Advance is made
prior to 1:00 p.m. Chicago time on a Business Day, then such Advance shall be
made by Lender on the date of such request. If such request is made at or after
1:00 p.m. Chicago time, then such Advance shall be made by Lender on the next
Business Day. Each request for an Advance shall be deemed a certification by
Borrower that no Event of Default exists or will be created if the requested
Advance is made. Lender shall not be obligated to make any Advance if: (i) an
Event of Default exists or will be created if the requested Advance is made; or
(ii) after making such Advance, the outstanding aggregate principal amount of
the Loan will exceed $1,000,000.00. "Business Day" means any day other than a
Saturday, Sunday or other day on which commercial banks in Chicago, Illinois are
required or permitted to be closed.
<PAGE>   2
         Interest shall be payable monthly in arrears from the date the proceeds
of any Advance under the Loan are made available to Borrower by Lender
hereunder, on the aggregate unpaid principal amount of the outstanding balance
outstanding from time to time, on the first Business Day of each month occurring
after the date of the first Advance under the Loan and continuing until the
Maturity Date of the Loan, whether by acceleration or otherwise. Principal owing
under the Loan shall be paid upon maturity of the Loan, whether by acceleration
or otherwise. Principal and interest shall be paid to Lender at its address set
forth above or at such other place as the holder of this Note shall designate in
writing to Borrower.

         As used herein, the term "Prime Rate" means the rate which LaSalle
National Bank, a national banking association ("LaSalle"), announces, publishes
or designates from time to time as its prime lending rate in effect at its
principal office in Chicago, Illinois. The Prime Rate is a reference rate and
does not necessarily represent the lowest or best rate actually charged by
LaSalle to any customer. Any change in the Prime Rate shall be effective for
purposes of this Note on the date of such change without notice to Borrower.
Interest shall be computed on the basis of a year consisting of 360 days and
shall be paid for the actual number of days elapsed.

         This Note is secured by a Security Agreement of even date herewith, and
all obligations of Borrower under this Note are subject to the terms and
conditions of a Subordination Agreement of even date herewith.

         It is understood and agreed that if any of the following events (herein
called an "Event of Default") shall occur:

         1.       Borrower fails to make any payment due and owing hereunder;

         2.       A "HouTex Event of Default" has occurred and is continuing
                  under the Loan Agreement dated as of January 7, 1997, by and
                  among Borrower, Lender and LaSalle (the "Loan Agreement")
                  beyond any applicable cure periods; or a default or event of
                  default has occurred or is continuing under any other
                  agreement of Borrower: (a) in respect of money borrowed, (b)
                  evidenced by a note, debenture or other like written
                  obligation to pay money, (c) in respect of rent or hire of
                  property (real, personal or mixed, whether tangible or
                  intangible) under capitalized leases or for the deferred
                  purchase price of any such property or (d) in respect of
                  obligations under conditional sales or other title retention
                  agreements, and all guaranties of any and all of the
                  foregoing;

         3.       Borrower applies for, consents to, or acquiesces in the
                  appointment of a trustee, receiver or other custodian for
                  Borrower, or in the absence of such application, a trustee,
                  receiver or other custodian is appointed for Borrower, or any
                  bankruptcy, reorganization, dissolution or liquidation
                  proceeding is instituted by or against Borrower;


                                       -2-

                  (h) Debtor shall (i) from time to time promptly execute and

         promptly notify Secured Party of any material adverse change in any
         facts or circumstances warranted or represented by Debtor in this

         sequestration, other legal or equitable process, or any encumbrance of
         any kind or character.

<PAGE>   4
                  (j) Should any part of the Collateral ever be in any manner
         converted by its issuer or maker into another type of property or any
         money or other proceeds ever be paid or delivered to Debtor as a result
         of Debtor's rights in the Collateral, then all such property, money and
         other proceeds shall become part of the Collateral, and Debtor
         covenants to forthwith pay or deliver to Secured Party all of the same
         which is susceptible of delivery and, at the same time, if Secured
         Party deems it necessary and so requests, Debtor will properly endorse
         or assign the same (provided that if no Event of Default then exists,
         Debtor shall not be required to deliver to Secured Party cash received
         in satisfaction of an account receivable, provided further that nothing
         in this clause is intended to affect or otherwise restrict the security
         interest granted to Secured Party in the proceeds of all Collateral).
         With respect to any of such property of a kind requiring any additional
         security agreement, financing statement or other writing to perfect a
         security interest therein in favor of Secured Party, Debtor will
         forthwith execute and deliver to Secured Party whatever Secured Party
         shall deem necessary or proper for such purpose.

                  (k) Should any covenant, duty or agreement of Debtor fail to
         be performed in accordance with its terms hereunder, Secured Party may,
         but shall never be obligated to, perform or attempt to perform such
         covenant, duty or agreement on behalf of Debtor, and any amount
         expended by Secured Party in such performance or attempted performance
         shall become a part of the indebtedness secured hereby, and, upon
         demand of Secured Party, Debtor agrees to pay such amount promptly to
         Secured Party, together with interest thereon at the Default Rate from
         the date of such expenditure by Secured Party until repaid to Secured
         Party.

         4. DEFAULT. An "Event of Default" shall occur under this Agreement only
upon the occurrence of (a) a breach by Debtor of any of the covenants,
agreements, representations, warranties or other provisions hereof which is not
cured or waived within the applicable grace or cure period, if any, set forth in
the Note, or (b) any breach by Debtor of any of its obligations under this
Agreement.

         5. SECURED PARTY'S RIGHTS AND REMEDIES. Secured Party shall have
available to it the following rights and remedies:

                  (a) Right to Assign. Secured Party may assign this Agreement,
         and if Secured Party does assign this Agreement, the assignee shall be
         entitled to the performance of all of Debtor's agreements and
         obligations under this Agreement, and the assignee shall be entitled to
         all the rights and remedies of Secured Party under this Agreement.
         Debtor expressly agrees that it will assert no claims or defenses it
         may have against Secured Party against the assignee except those
         available to it pursuant to this Agreement.

                  (b) Right to Discharge Debtor's Obligations. Secured Party
         may, at its option, discharge taxes, liens or security interests or
         other encumbrances at any time levied or placed on the Collateral, may
         remedy or cure any default of Debtor under the terms of any lease,


                                        4
<PAGE>   5
         rental agreement, or other document which in any way pertains to or
         affects Debtor's title to or interest in any of the Collateral, may pay
         for insurance on the Collateral, and may pay for the maintenance and
         preservation of the Collateral, and Debtor agrees to reimburse Secured
         Party, on demand, for any payment made or any expense incurred by
         Secured Party, including reasonable attorneys' fees, pursuant to the
         foregoing authorization, together with interest at the Default Rate
         from the date so paid or incurred by Secured Party until repaid to
         Secured Party, which payments, expenses and interest shall be secured
         by this Agreement and by the other Loan Documents.

                  (c) Rights as Secured Creditor. Upon the occurrence of an
         Event of Default, Secured Party, in its sole and absolute discretion,
         may: (a) exercise any one or more of the rights and remedies afforded
         to secured parties under the Uniform Commercial Code in force in the
         State(s) in which the Collateral is located, together with any and all
         other rights and remedies otherwise provided and available to Secured
         Party at law or in equity; (b) enter, with process of law and without
         breach of the peace, any premises where the Collateral (or the books
         and records of Debtor related thereto) is or may be located, and
         without charge or liability to Secured Party therefor seize and remove
         the Collateral (and copies of Debtor's books and records in any way
         relating to the Collateral) from said premises and/or remain upon said
         premises and use the same (together with said books and records) for
         the purpose of collecting, preparing and liquidating the Collateral,
         all without cost to Secured Party; and (c) upon prior notice to Debtor
         as required by this Agreement, sell or otherwise dispose of the
         Collateral at public or private sale or auction for cash or credit
         (which sale or auction may, at the option of Secured Party, occur on
         the premises where the Collateral is located or elsewhere, at no cost
         to Secured Party) and from the proceeds of such sale or disposal retain
         (i) all costs and charges incurred by Secured Party in taking and
         causing the removal and sale or disposal of the Collateral, including
         reasonable attorneys' fees; and (ii) an amount equal to all other
         Obligations; provided, however, that Debtor shall be credited with the
         net proceeds of such sale only when such proceeds are actually received
         by Secured Party.

                  (d) Assembly of Collateral; Injunctive Relief. Upon the
         occurrence of an Event of Default, Debtor, immediately upon demand by
         Secured Party, shall assemble the Collateral and make it available to
         Secured Party at a place or places to be designated by Secured Party.
         Debtor hereby acknowledges and agrees that if Debtor fails to perform,
         observe or discharge any of its obligations or liabilities under this
         Agreement, no remedy of law shall provide adequate relief to Secured
         Party, and that Secured Party shall be entitled to temporary and
         permanent injunctive relief in any such case without the necessity of
         proving actual damages or the posting of bond, surety or other
         security.

                  (e) Notice of Collateral Disposition. Any notice required to
         be given by Secured Party of a sale, lease or other disposition of the
         Collateral or any other intended action by Secured Party, sent by
         registered or certified United States mail, postage prepaid and duly
         addressed to Debtor at Debtor's address set forth in the Note not less
         than ten days prior to

                                        5
<PAGE>   6
         such proposed action, shall constitute commercially reasonable and fair
         notice to Debtor thereof.

                  (f) Matters Regarding Sale of Collateral. Debtor agrees that
         Secured Party may, if Secured Party deems it reasonable, postpone or
         adjourn any sale of Collateral from time to time by an announcement at
         the time and place of sale or by announcement at the time and place of
         such postponed or adjourned sale, without being required to give a new
         notice of sale. Debtor also waives and releases any right of Debtor to
         redeem the Collateral from such sale. At any sale or sales made
         pursuant to this Agreement or in a suit to foreclose the same, the
         Collateral, at the option of Secured Party or its assigns, may be sold
         in its entirety or separately, at the same or at different times, and
         the Collateral need not be present at the time or place of sale. At any
         such sale, Secured Party or the holder of the indebtedness hereby
         secured may bid for and purchase any of the property sold,
         notwithstanding that such sale is conducted by Secured Party or its
         attorneys, agents, or assigns, and no irregularity in the manner of
         sale or of giving notice shall operate to preclude Secured Party from
         recovering the Obligations.

                  (g) Replevin. If Secured Party seeks possession of the
         Collateral through replevin or other court action, Debtor hereby
         irrevocably waives (i) any bond, surety or security required as an
         incident to such possession, and (ii) any demand by Secured Party for
         possession of the Collateral prior to the commencement of any such suit
         or action.

                  (h) Enforcement Standards. Secured Party shall have the right
         at all times to enforce the provisions of this Agreement in strict
         accordance with the terms hereof, notwithstanding any conduct or custom
         on the part of Secured Party in refraining from so doing at any time or
         times. The failure of Secured Party at any time or times to enforce its
         rights under said provisions strictly in accordance with the same shall
         not be construed or operate as a waiver of any of the rights and
         remedies granted Secured Party hereunder or as having created a custom
         in any way or manner contrary to the specific provisions of this
         Agreement or as having in any way or manner modified the same. All
         rights and remedies of Secured Party are cumulative and concurrent, and
         the exercise of one right or remedy by Secured Party shall not be
         deemed a waiver or release of any other right or remedy.

         6. REPRESENTATIONS AND WARRANTIES. Debtor represents and warrants that:

                  (a) Debtor has authority to execute and deliver this
         Agreement;

                  (b) no financing statement covering the Collateral, or any
         part thereof, has been filed and remains in effect, other than securing
         a first lien on the Collateral in favor of LaSalle National Bank;


                                        6
<PAGE>   7
                  (c) no other security agreement covering the Collateral, or
         any part thereof, has been made and no security interest, other than
         the one herein created, has attached or been perfected in the
         Collateral or in any part thereof other than to LaSalle National Bank;

                  (d) no material dispute, right of setoff, counterclaim or
         defense exists with respect to any part of the Collateral;

                  (e) all information supplied and statements made in any
         financial or credit statements or application for credit prior to the
         execution of this Agreement are true and correct in all material
         respects as of the date hereof;

                  (f) at the time Secured Party's security interest attaches to
         any of the Collateral or its proceeds, Debtor will be the lawful owner
         with the right to transfer any interest therein, and Debtor will make
         such further assurances as to prove title to the Collateral in Secured
         Party as may be required and will defend the Collateral and its
         proceeds against the lawful claims and demands of all persons
         whomsoever.

                  (g) There is listed on EXHIBIT A hereto the location of the
         principal place of business of Debtor, all of the other places of
         business of Debtor and all locations where all tangible Collateral and
         the books and records of Debtor are kept. Debtor shall not change the
         location of (i) its places of business or its books and records, or
         (ii) any tangible Collateral, without in each case providing not less
         than thirty days prior written notice thereof to Secured Party.

                  (h) All trade or assumed names under which Debtor has done or
         proposes to do business are listed on EXHIBIT B. Debtor shall give
         Secured Party not less than thirty days prior written notice of any
         change in Debtor's name or any new or change in any trade name that
         Debtor uses in its business.

The delivery at any time by Debtor to Secured Party of the Collateral shall
constitute a representation and warranty by Debtor that, with respect to such
Collateral, and each item thereof, Debtor is owner of the Collateral and the
matters heretofore represented and warranted in this Paragraph 6 are true and
correct. Further, Debtor, upon the request of Secured Party, agrees to amend
this Agreement and any and all financing statements filed in connection
therewith for the purpose of setting forth in said Agreement and said financing
statements an accurate and itemized list of the Collateral now generally
described herein and in said financing statements and to include in said
accurate and itemized list an identification of the Collateral by make, model,
serial number and other appropriate descriptive data.

         7. SUBROGATION. If the Obligations, or any part thereof, are renewed or
extended, or applied toward the payment of any indebtedness secured by any
mortgage, pledge, security agreement or other lien, Secured Party shall be and
is hereby subrogated to all of the rights, titles, security interests and other
liens securing the indebtedness so renewed, extended or paid.

         8. FURTHER AGREEMENTS.

                  (a) "Debtor" and "Secured Party" as used in this Agreement
         include the legal representatives, successors and assigns of those
         parties.

                  (b) Neither Debtor nor Secured Party shall be bound by any
         amendment not expressed in writing and signed by the party to be bound
         thereby.

                  (c) It is expressly intended, understood and agreed: (i) that
         this Agreement is made and entered into for the sole protection and
         benefit of Secured Party and Debtor, and their successors and assigns
         and no other person or persons shall have any right of action hereunder
         or rights to the proceeds of the Line of Credit at any time; (ii) that
         the proceeds of the Line of Credit do not constitute a trust fund for
         the benefit of any third party; and (iii) that no third party shall
         under any circumstances be entitled to any equitable lien on any
         undisbursed proceeds of the Line of Credit at any time. The
         relationship between Secured Party and Debtor is solely that of a
         lender and borrower, and nothing contained herein, or in the Note, the
         Guaranty or any of the other Loan Documents shall in any manner be
         construed as making the parties hereto partners, joint venturers or as
         creating any relationship other than lender and borrower.

                  (d) This Agreement shall be construed in accordance with and
         governed by the laws of the State of Illinois. In the event that any
         provision of this Agreement is deemed to be invalid by reason of the
         operation of law, or by reason of the interpretation placed thereon by
         any administrative agency or any court, Debtor and Secured Party shall
         negotiate an equitable adjustment in the provisions of the same in
         order to effect, to the maximum extent permitted by law, the purpose of
         this Agreement and the validity and enforceability of the remaining
         provisions, or portions or applications thereof, shall not be affected
         thereby and shall remain in full force and effect.

                  (e) To the extent permitted by law, Debtor hereby waives any
         and all rights to require marshalling of assets.

                  (f) All notices, demands, requests and other correspondence
         which are required or permitted to be given hereunder shall be deemed
         sufficiently given when delivered or mailed in the manner and to the
         address of Debtor or Secured Party, as the case may be, as specified in
         the Note.

                  (g) This Agreement shall inure to the benefit of Secured Party
         and its successors and assigns and shall be binding upon Debtor and its
         successors and assigns.

                  (h) DEBTOR AND SECURED PARTY ACKNOWLEDGE AND AGREE THAT ANY
         CONTROVERSY WHICH MAY ARISE UNDER THE NOTE, THIS AGREEMENT, THE
         GUARANTY, THE NOTE OR ANY OF THE OTHER LOAN

                                        8
<PAGE>   9
         DOCUMENTS OR WITH RESPECT TO THE TRANSACTIONS CONTEMPLATED HEREIN AND
         THEREIN WOULD BE BASED UPON DIFFICULT AND COMPLEX ISSUES. ACCORDINGLY,
         TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, DEBTOR AND SECURED
         PARTY HEREBY KNOWINGLY AND VOLUNTARILY MUTUALLY (A) WAIVE THE RIGHT TO
         TRIAL BY JURY IN ANY CIVIL ACTION, CLAIM, COUNTERCLAIM, CROSS-CLAIM,
         THIRD-PARTY CLAIM, DISPUTE, DEMAND, SUIT OR PROCEEDING ARISING OUT OF
         OR IN ANY WAY CONNECTED WITH THE NOTE THIS AGREEMENT, THE GUARANTY, THE
         NOTE OR ANY OF THE OTHER LOAN DOCUMENTS, THE LINE OF CREDIT, OR ANY
         RENEWAL, EXTENSION OR MODIFICATION THEREOF, OR ANY CONDUCT OF ANY PARTY
         RELATING THERETO, AND (B) AGREE THAT ANY SUCH ACTION, CLAIM, SUIT OR
         PROCEEDING SHALL BE TRIED BEFORE A JUDGE AND NOT BEFORE A JURY.

         IN WITNESS WHEREOF, the undersigned has executed this Agreement as of
the day and year first above written.

                                LETTER AGREEMENT


         This Letter Agreement ("Agreement"), is made and entered into as of the
7th day of January, 1997, by and between Metal Management, Inc., a Delaware
corporation ("MMI"), and HouTex Metals Company, Inc., a Texas corporation
("HouTex").

                                R E C I T A L S:

         A. MMI and HouTex have executed a loan agreement (the "Loan Agreement")
with LaSalle National Bank, a national banking association ("Lender"), of even
date herewith, whereby Lender has agreed to provide MMI with a term loan in the
amount of $6,500,000, and to HouTex a revolving line of credit in the maximum
amount of $3,500,000.

         B. In connection with the Loan Agreement, there are certain obligations
delegated to MMI and HouTex jointly, which the parties desire to divide among
themselves.

         NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties agree as follows:

         1. All capitalized terms not otherwise defined in this Agreement shall
have the meanings ascribed to such terms in the Loan Agreement.

         2. In Section 2.7 of the Loan Agreement, MMI and HouTex are granted the
right to extend the MMI Loan and the HouTex Loan for an additional period of
three months by delivering a written notice to the Lender and paying a
non-refundable extension fee equal to $25,000 (the "Extension Fee"). In the
event that both MMI and HouTex extend the MMI Loan and the HouTex Loan, MMI
shall pay $13,750 of the Extension Fee, and HouTex shall pay the remaining
$11,250 of the Extension Fee.

         3. Pursuant to Section 2.8 of the Loan Agreement, MMI and HouTex have
agreed to pay to Lender a non-refundable loan fee in the amount of $15,000. MMI
and HouTex hereby agree that such fee shall be payable in full by MMI on the
Closing Date of the Loan Agreement.


         4. Pursuant to Section 9 of the Loan Agreement, MMI and HouTex have
agreed to pay to the Lender on demand all fees paid and expenses incurred by
Lender in connection with the transactions contemplated by the Loan Agreement,
any amendments, modifications or waivers under or in respect of any of the Loan
Documents and in connection with the preparation of the Loan Documents (the
"Transactions Fees"). MMI and HouTex hereby agree that all of the Transaction
Fees incurred in connection with the initial loan Closing shall be paid by MMI,
and HouTex shall be responsible only for the fees and expenses incurred in
enforcement of Lender's rights against HouTex pursuant to the Loan Agreement or
for any modifications of the HouTex Loan.


                                       1
<PAGE>   2
         5. In the event that HouTex exercises its Extension Right pursuant to
Section 2.7 of the Loan Agreement, MMI does hereby agree to exercise its
Extension Right unless either (a) Lender has increased the amount available to
HouTex under the HouTex Loan to at least $5,500,000, or (b) MMI has obtained
other financings or has funds otherwise available sufficient to fund the
Revolving Credit Note from HouTex to MMI in the initial principal amount of
$1,000,000 dated January 7, 1997 (the "HouTex Revolver") and MMI agrees to
extend the HouTex Revolver to the Extended Maturity Date pursuant to the Loan
Agreement.

         IN WITNESS WHEREOF, the parties have executed this Letter Agreement as
of the date and year first above written.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                        (ALL DOLLAR AMOUNTS IN THOUSANDS)



NOTE 1 - THE COMPANY AND ITS SIGNIFICANT ACCOUNTING POLICIES:

Hou-Tex Metals Company, Inc. (the Company) is engaged in the dismantling,
processing, marketing, brokering and recycling of ferrous and nonferrous metals.
These services are provided through its location in Houston, Texas, on property
which has barge access to the Houston Ship Channel.

Consolidated financial statements

The accompanying consolidated financial statements include the accounts of the
Company and its majority-owned subsidiary. All significant intercompany accounts
and transactions have been eliminated in consolidation.

Fiscal year

The Company's fiscal year ends on September 30.

Uses of estimates

The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results may differ from these estimates.

Cash equivalents

Highly liquid investments with original maturities of three months or less are
classified as cash equivalents.

Accounts receivable

Accounts receivable represent amounts due from customers on product sales. An
allowance for doubtful accounts has not been provided as losses are not
anticipated on the realization of the accounts receivable. A reserve for tonnage
variances has been provided at June 30, 1996 to account for differences in
shipment weights which are settled on a quarterly basis.

Inventories

Inventories consist of ferrous, nonferrous, pipe and other material and are
carried at the lower of first-in, first-out cost or market.

Property and equipment

Property and equipment are recorded at cost less accumulated depreciation. Major
renewals and improvements are capitalized while repairs and maintenance are
expensed as incurred. Depreciation is computed using the straight-line method
over estimated useful lives of 31.5 to 39 years for buildings and improvements,
5 to 7 years for equipment, furniture and fixtures and 3 to 5 years for
vehicles. When assets are sold or otherwise disposed of, the cost and related
accumulated depreciation are removed from the accounts and any gain or loss is
included in results of operations.

Revenue recognition

The Company recognizes revenue when title passes to the customer, which
generally occurs at the time of shipment.

Income taxes

The Company utilizes the liability method of accounting for income taxes, as set
forth in Statement of Financial Accounting Standards No. 109, "Accounting for
Income Taxes". Under the liability method, deferred income taxes are determined
based on the difference between the financial statement and tax bases of assets
and liabilities using enacted tax rates in effect in the years in which the
differences are expected to reverse.

Investment securities

As of October 1, 1994, the Company adopted Statement of Financial Accounting
Standards No. 115 (SFAS 115), Accounting for Certain Investments in Debt and
Equity Securities. In accordance with SFAS 115, prior year's financial
statements have not been restated to reflect the change in accounting method.
Under this statement, the Company's marketable securities have been classified
as available for sale and are recorded at current market value with an
offsetting adjustment to stockholders' equity. The adoption of this statement
did not have a significant effect on the Company's consolidated financial
position. At September 30, 1994, marketable securities were carried at the lower
of cost or market.

Major customers and concentration of credit risk

Three customers represented 83%, 86% and 78% of revenues for the nine months
ended June 30, 1996 and the years ended September 30, 1995 and 1994,
respectively. These customers comprised approximately 90%, 78% and 80% of
accounts receivable at June 30, 1996, September 30, 1995 and September 30, 1994,
respectively. No other customer comprised more
<PAGE>   8
                                      - 3 -

than 10% of total sales for any period or more than 10% of accounts receivable
for any period presented.

Financial instruments that potentially subject the Company to significant
concentration of credit risk are primarily trade accounts receivable. The
Company sells its products primarily to scrap metal brokers and steel mills
located in the southwestern region of the United States. Generally, the Company
does not require collateral or other security to support customer receivables.
Historically, the Company has not experienced material losses from the
noncollection of receivables.

NOTE 5 - LONG-TERM DEBT:

In March 1992, the Company entered into a $1,000 revolving line of credit with a
commercial lender which was subsequently increased to $2,000, $3,500 and $6,000
as of September 30, 1994, September 30, 1995 and June 30, 1996, respectively.
The line of credit matures June 30, 1997. Borrowings against the line of credit
bear interest at prime plus 1% and are secured by the Company's accounts
receivable and inventories. The Company is presently in default of its covenants
related to its line of credit. Consequently, this debt is payable on demand.

The Company leases certain equipment under a capital lease agreement with an
effective interest rate of 10 percent. Future minimum lease payments under these
agreements are included in other long-term debt.

Income taxes have been provided based on the statutory graduated tax rates
adjusted for items which are allowed as deductions for federal income tax
reporting purposes but not for book purposes. The primary differences between
the statutory rates and the Company's effective rates relate to nondeductible
expenses and an alternative minimum tax credit carryforward.

NOTE 7 - COMMITMENTS AND CONTINGENCIES:

Leases

The Company leases vehicles and equipment under noncancelable operating lease
agreements. The leases expire at various dates through January 1997. As of June
30, 1996, future minimum lease payments under these agreements were $14 and $8
for the three months ended September 30, 1996 and fiscal year ended September
30, 1997, respectively.

Rent expense totaled $14 for the nine months ended June 30, 1996, $14 for the
year ended September 30, 1995 and $58 for the year ended September 30, 1994.

Litigation

The Company is party to various lawsuits and claims arising in the normal course
of its business. In management's opinion, based on discussion with legal
counsel, the ultimate disposition of these lawsuits and claims will not have a
material adverse effect upon the Company's financial position or operations.

NOTE 8 - SUBSEQUENT EVENT:

Subsequent to June 30, 1996, the Company entered into a letter of intent to sell
all of its stock to an unrelated third party. These financial statements make no
provision for the outcome of this transaction.

                        REPORT OF INDEPENDENT ACCOUNTANTS


January 6, 1997

To the Board of Directors and Stockholders of
Hou-Tex Metals Company, Inc.


In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of income, of stockholders' equity and of cash flows
present fairly, in all material respects, the financial position of Hou-Tex
Metals Company, Inc. at June 30, 1996, September 30, 1995 and September 30,
1994, and the results of their operations and their cash flows for the nine
months ended June 30, 1996 and the years ended September 30, 1995 and 1994, in
conformity with generally accepted accounting principles. These financial
statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audit. We conducted our audit of these statements in accordance with
generally accepted auditing standards which require that we plan and perform the
audit to obtain reasonable assurance about whether the financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audit provides a reasonable basis for the opinion expressed
above.

As discussed in Note 5, the Company is not in compliance with all of its debt
covenants related to its line of credit. Consequently, this line of credit is
payable on demand.
