ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS

     Effective August 28, 1997, Metal Management, Inc. (the "Company" or the
"Registrant") closed its acquisition of the scrap recycling businesses of
Proler Southwest, Inc., a Texas corporation ("Southwest") and Proler
Steelworks, L.L.C., a Delaware limited liability company
("Steelworks")(together, the "Proler Group"), headquartered in Houston, Texas.

     Southwest and Steelworks were founded in 1992 and 1994, respectively,
principally by William and Ronald Proler.  The Proler Group operates a
recycling facility in Houston, Texas and a recycling facility in Jackson,
Mississippi.  The Company intends to continue such use of these facilities.

     The Company acquired the Proler Group for consideration consisting of: (i)
$7.5 million in cash; (ii) promissory notes in the aggregate amount of
$2,400,000 maturing two years from the closing date and bearing interest at 7%
per year; (iii) promissory notes in the aggregate amount of $8,100,000 maturing
March 1, 1998 and bearing interest at 8% per year for the first ninety days
following closing, and increasing to 10%, 12% and 14% per year for each of the
subsequent thirty-day periods; (iv) 1,750,000 shares of Common Stock of the
Company; and (v) warrants exercisable for a period of five years to purchase up
to 375,000 shares of Common Stock of the Company at an exercise price of $6.00
per share.  The Company paid the cash portion of the consideration from working
capital. The amount of consideration paid by the Company in the acquisition of
the Proler Group was determined in arm's-length negotiations with the Proler
Group.

     William T. Proler has joined the Company as a director and entered into a
five-year employment agreement with the Company.  The employment agreement
provides for an annual salary of $225,000, plus a guaranteed bonus equal to
twenty five percent of the base salary. Additionally, four other previous
shareholders of the Proler Group entered into employment agreements with the
Company.

All of the statements herein, other than historical facts, are forward-looking
statements made in reliance upon the Safe Harbor Provisions of the Private
Securities Litigation Reform Act of 1995.  As such, they involve risks and 
uncertainties and are subject to change at any time.  These statements reflect
the Company's current expectations regarding the future profitability of the 
Company and its subsidiaries and the benefits to be derived from the Company's
execution of its industry consolidation strategy.  There can be no assurance 
that the Company's actual future performance or that of its subsidiaries will 
meet the Company's expectations for growth and profitability.  The statements 
in this Form 8-K involve known and unknown risks, uncertainties, and other 
factors which may cause actual results, performance, or achievements to be 
materially different from any future results, performance, or achievements 
expressed or implied by these forward-looking statements.  As discussed in the
Company's annual report for the period ended March 31, 1997 and its quarterly 
report for the period ended June 30, 1997, some of  the factors which could 
affect the Company's performance include, among other things, cyclicality of 
the scrap metal recycling industry, price fluctuations in commodity markets, 
adverse economic conditions, inability to successfully access capital, 
unavailability of suitable acquisition opportunities, the cost of 

                                      1

complying with environmental laws and regulations, the risk that announced 
mergers are not consummated, the risk of challenges by the Company's 
competition, and the risk that the Company will face difficulties in 
consolidating and controlling operations in diverse geographic locations.

Company with and into Acquisition (the "Merger") pursuant to which the shares

      WHEREAS, the parties hereto wish to set forth the representations,
warranties, agreements and conditions under which a merger (the "Merger") of

                        THE MERGER AND RELATED MATTERS

      1.1   MERGER.

            (a)   Upon the terms and subject to the conditions of this 
      Agreement, the Company shall be merged with and into Acquisition in
      accordance with the Texas Business Corporation Act ("TBCA"). Acquisition

      Corporation").  The Surviving Corporation shall continue its corporate
      existence under and be organized under and be governed by the TBCA and
      possess all the rights and assets of Acquisition and the Company and be

<PAGE>   3


            (b)   The Articles of Incorporation and the Bylaws of Acquisition,  
      as in effect immediately prior to the date and time when the Merger shall
      become effective (the "Effective Time"), shall be the Articles of
      Incorporation and Bylaws, respectively, of the Surviving Corporation
      until thereafter amended, except that Article One of the Articles of
      Incorporation of Acquisition shall be amended to change the name of
      Acquisition to "Proler Southwest Inc."

            (c)   The directors of Acquisition immediately prior to the         
      Effective Time shall be the directors of the Surviving Corporation and

      Surviving Corporation, or as otherwise provided by law.

            (d)   The Merger shall have the effects set forth in the TBCA.  If

      record or otherwise, in the Surviving Corporation, all rights, title and
      interests in all real estate and other property and all privileges,
      powers and franchises of the Company and Acquisition, the Surviving
      Corporation and its proper officers and directors, in the name and on
      behalf of the Company and Acquisition, shall execute and deliver all such
      proper deeds, assignments and assurances in law and do all things

      purpose of this Agreement, and the proper officers and directors of the
      Surviving Corporation are fully authorized in the name of the Company or
      otherwise to take any and all such action.

be effective when properly executed Articles of Merger (together with any other
documents required by law to effectuate the Merger) shall have been filed with
the Secretary of State of the State of Texas in accordance with the provisions
of the TBCA, which filing shall be made as soon as practical on or after the
Effective Time.

      1.3   CONVERSION OF STOCK.

            (a)   At the Effective Time, by virtue of the Merger and without any

      the 10,000 shares of Company Common Stock outstanding immediately prior
      to the Effective Time shall be converted into 


                                      2
<PAGE>   4


      the right of the Shareholders to receive in the manner allocated on 
      Annex A hereto, upon the surrender of the certificates formerly
      representing such shares the following (the "Merger Consideration"):

                 (i)    1,750,000 shares of MTLM Common Stock, of which 250,000
                        shares shall be placed in escrow pursuant to an Escrow
                        Agreement (the "Escrow Shares"), the form of which
                        Escrow Agreement is attached hereto as Exhibit A and
                        made a part hereof;

                 (ii)   $2,000,000 principal amount of purchase notes
                        ("Purchase Notes") in the form of Exhibit B attached
                        hereto and made a part hereof;

                 (iii)  Warrants in the forms of Exhibits C, D and E,
                        respectively, to purchase 100,000 shares of MTLM Common
                        Stock (the "Conversion Warrant"), 225,000 shares of
                        MTLM Common Stock (the "Cash Warrant") and 50,000
                        shares of MTLM Common Stock (the "Employee Warrant");

                 (iv)   $7,500,000 principal amount of 180-day promissory notes
                        (the "180-day Notes") in the form of Exhibit F attached
                        hereto and made a part hereof;

                 (v)    $600,000 principal amount of notes reflecting the
                        post-tax earnings of the Company from January 1, 1997
                        to March 18, 1997 (the "Earnings Notes") in the form of
                        Exhibit G attached hereto and made a part hereof; and;

                 (vi)   $5,500,000 in cash.

            (b)  No fractional shares of MTLM Common Stock shall be issued to   
      any holder of Company Common Stock in the Merger.  To the extent the
      application of the conversion rate to all shares of Company Common Stock
      held by a Shareholder would result in a fractional number of shares of
      MTLM Common Stock being issued to such holder in the Merger, the number
      of shares of MTLM Common Stock issuable to such holder in respect of all
      such shares in the Merger shall be rounded up to the next whole number of
      shares of MTLM Common Stock.

            (c)  Each share of Acquisition Common Stock outstanding immediately
      prior to the Effective Time shall continue to be one share of stock in the
      Surviving Corporation.

            (d)  As of and after the Effective Time, no holder of any   
      certificate that immediately prior to the Effective Time represented
      shares of Company Common Stock shall have any rights as a holder of
      Company Common Stock other than to receive the Merger Consideration
      issuable to such holder pursuant to the Merger.


                                      3

      1.4 ESCROW.

      The Escrow Shares will be held under the Escrow Agreement for a period of
one year for the purposes of satisfying the amount, if any, due the Company or
MTLM as a result of any breaches of the Company's representations and
warranties that occur within said one year period.  At the end of such one year
period shares not deducted from the escrow, as provided above, shall be
delivered by the Escrow Agent to the Shareholders.

      1.5 EXCHANGE.

      At the Closing, each Shareholder shall surrender to MTLM the certificates
for Company Common Stock owned by such Shareholder.  Until so surrendered,
certificates for shares of Company Common Stock shall represent, after the
Effective Time, solely the right to receive the Merger Consideration issuable
in respect of such shares determined pursuant to Section 1.3 hereof.


                                  ARTICLE II

                        REPRESENTATIONS AND WARRANTIES

to the Company, (i) the name, address and federal taxpayer identification
number of, and the number of outstanding shares of each class of its capital
stock owned by each shareholder of record as of the close of business on the

identification number of, and number of shares of each class of its capital
stock beneficially owned by, each beneficial owner of outstanding shares of
capital stock (to the extent that record and beneficial ownership is
different).  The Shareholders are the holders of all issued and outstanding
shares of capital stock of the Company and the Shareholders own such shares as
set forth on Schedule 3.5, free and clear of all Liens, restrictions and claims
of any kind, except as set forth on Schedule 3.5.  Such shares are not subject
to any voting trust agreement, proxy or other Contract.

                               INDEMNIFICATION

      8.1  AGREEMENT BY THE SHAREHOLDERS TO INDEMNIFY.  The Shareholders agree  
to severally indemnify, defend and hold MTLM harmless (with each Shareholder's
liability to MTLM being equal to such Shareholder's proportionate share, as set
forth in Schedule 3.1 hereto, of any Indemnifiable Damages, subject to the
limitations set forth in Section 8.1(e) below) from and against the aggregate
of all Indemnifiable Damages (as defined below).

            (a)  For purposes of this Agreement, "Indemnifiable Damages" means,
      without duplication, the aggregate of all actual expenses, losses, costs,
      deficiencies, liabilities and damages (including, without limitation,
      related counsel and paralegal fees and expenses) incurred or suffered by
      MTLM, on a pre-tax consolidated basis to the extent (i) resulting from
      any breach or inaccuracy of a representation or warranty made by the
      Company or the Shareholders in or pursuant to this Agreement, (ii)
      resulting from any breach of the covenants or agreements made by the
      Company or the Shareholders pursuant to this Agreement, (iii) resulting
      from any inaccuracy in any certificate or environmental report delivered
      by the Company or any Shareholders pursuant to this Agreement, or (iv)
      resulting from, arising out of, relating to, in the nature of, or caused
      by any liability of the Company (x) for any Taxes of the Company with
      respect to any tax year or portion thereof ending on or before the
      Closing Date to the extent such Taxes are not reflected in the reserve
      for tax liability (rather than any reserve for deferred Taxes established
      to reflect timing differences between book and tax income) shown on the
      face of the Current Balance Sheet (rather than any notes thereto) and (y)
      for the unpaid Taxes of any Person (other than the Company) as a
      transferee or successor by contract, or otherwise.

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

            (c)  Each of the representations and warranties made by the         
      Shareholders in this Agreement or pursuant hereto shall survive for a
      period of 12 months after the Closing Date except as follows:  (i) the
      representations and warranties of the Shareholders contained in Section
      3.19, to the extent relating to tax attributes or liabilities with
      respect to Taxes of the Company, shall expire at the time the period of
      limitations (including any extensions thereof pursuant to the delivery of
      waivers (agreed to by the Shareholders) 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 


                                      34
<PAGE>   36


      warranties of the Shareholders contained in Sections 3.13 and 3.18 shall  
      survive for a period of 24 months after the Closing Date; and (iii) the
      representations and warranties of the 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 against the 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 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)  If MTLM believes it is entitled to a claim for any 
      Indemnifiable Damages hereunder, MTLM shall promptly give written notice  
      to the Shareholders of such claim and the amount or the estimated amount
      of such claim, and the basis for such claim.  If the Shareholders do not
      pay the amount of the claim for Indemnifiable Damages to MTLM within 10
      days, then MTLM may exercise its respective rights under Section 8.4
      and/or take any action or exercise any remedy available to it by
      appropriate legal proceedings to collect the Indemnifiable Damages.

            (e)  Notwithstanding anything to the contrary contained in this 
      Section 8.1, the Shareholders' liability for Indemnifiable Damages shall
      be limited as follows:

                 (i)    MTLM shall have no claim for Indemnifiable Damages
                        unless and until all Indemnifiable Damages incurred by
                        MTLM exceed an aggregate of $250,000, in which event
                        the Shareholders shall be liable for only such
                        Indemnifiable Damages in excess of $250,000; provided,
                        however, that the $250,000 deductible provided above
                        shall not be applicable for any Indemnifiable Damages
                        relating to Taxes; and

                 (ii)   the total amount of Indemnifiable Damages for which the
                        Shareholders shall be liable to MTLM shall not exceed
                        the principal and interest due on the Purchase Notes
                        and the value of the Escrow Shares, which shall be
                        valued as provided in Section 8.4(a)(iv).

            (f)  The remedies set forth in this Section 8.1 shall be the 
      exclusive remedies of MTLM under this Agreement.

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


                                      35
<PAGE>   37


            (a)  For purposes of this Agreement, "Shareholders Indemnifiable    
      Damages" means, without duplication, the aggregate of all expenses,
      losses, costs, deficiencies, liabilities and damages (including, without
      limitation, reasonable related counsel and paralegal fees and expenses)
      incurred or suffered by the 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 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 Shareholders Indemnifiable Damages, the
      Shareholders 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 Closing Date, notwithstanding any investigation at any time made by
      or on behalf of the Shareholders, and upon expiration of such one year
      period, such representations and warranties shall expire, except for the
      representations contained in Sections 2.1, 2.2, 2.3 and 2.4 shall not
      expire, but shall continue indefinitely.  No claim for the recovery of
      Shareholders Indemnifiable Damages may be asserted by the Shareholders
      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 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 Shareholders believe they are entitled   
      to a claim for any Indemnifiable Damages hereunder, the 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 contained in this     
      Section 8.2, the Shareholders shall have no claim for Indemnifiable
      Damages unless and until all Indemnifiable Damages incurred by the
      Shareholders shall exceed an aggregate of $250,000, in which event MTLM
      shall be liable for only such Indemnifiable Damages in excess of
      $250,000.



                                      36
<PAGE>   38


            (f)  The remedies set forth in this Section 8.2 shall be the        
      exclusive remedies of the Shareholders under this Agreement.

      8.3  CONDITIONS OF INDEMNIFICATION.  The obligations and liabilities of   
the Shareholders and MTLM 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 10 business days after
      the Indemnified Party receives notice thereof;

            (b)  the Indemnifying Party shall have the right to undertake, by   
      counsel or other representatives of its own choosing, the defense of such
      Claim; provided, however, if a Claim is made against MTLM, then MTLM
      shall have the right to control the defense of the Claim;

            (c)  if 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 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  ESCROW SHARES AND RIGHTS OF SETOFF TO SECURE THE SHAREHOLDERS'
INDEMNIFICATION OBLIGATION.  As security for the agreement by the Shareholders  
to indemnify and hold MTLM harmless as described in Section 8.1, at the
Closing, MTLM shall cause the certificates representing the Escrow Shares to be
held under the Escrow Agreement.

            (a)  MTLM may set off against the Purchase Notes and thereafter the
      Escrow Shares (provided, however, the Shareholders may elect to satisfy
      any indemnification 


                                      37
<PAGE>   39

      obligation payable in Escrow Shares by a payment in cash) for any loss,
      damage, cost or expense for which the Shareholders may be responsible
      pursuant to this Agreement (including without limitation, any
      Indemnifiable Damages for which the 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:

                 (i)    MTLM shall give written notice to the Shareholders of
                        any claim for Indemnifiable 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;

                 (ii)   Such set off shall be effected on the later to occur of
                        the expiration of 10 business 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 Purchase Notes and
                        thereafter the Escrow Shares;

                 (iii)  If, prior to the expiration of the Notice of Contest
                        Period, the 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 arbitrators (one appointed by the
                        Shareholders, one appointed by MTLM and one appointed
                        by the two arbitrators so appointed), which shall be
                        appointed within 30 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;

                 (iv)   For purposes of this Section 8.4, the value for
                        purposes of set off of the Escrow Shares shall be the
                        average of the closing bid and asked prices of MTLM's

      The Parties agree as follows with respect to the sale or other disposition
after the Closing Date of MTLM securities:

      9.1  DISPOSITION OF MTLM SECURITIES.  Each of the Shareholders represents 
and warrants that each of the MTLM Securities being acquired by him hereunder
is being acquired and will be acquired for his own account and will not be sold
or otherwise disposed of, except pursuant to (i) an exemption from the
registration requirements under the Securities Act, which does not require the
filing by MTLM with the SEC of any registration statement, offering circular or
other document, in which case the Shareholders shall first supply to MTLM an
opinion of counsel (which counsel and opinions shall be satisfactory to MTLM)
that such exception is available, or (ii) an effective registration statement
filed by MTLM with the SEC under the Securities Act.

      9.2  LEGEND.  Each of the MTLM securities shall bear the following legend:

      THE SHARES OF COMMON STOCK REPRESENTED BY THIS CERTIFICATE MAY NOT BE
      SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF BY THE HOLDER EXCEPT PURSUANT
      TO AN EFFECTIVE REGISTRATION STATEMENT FILED UNDER THE SECURITIES ACT OF
      1933, AS AMENDED WITH RESPECT THERETO OR IN ACCORDANCE WITH AN OPINION OF
      COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER THAT AN
      EXEMPTION FROM SUCH REGISTRATION IS AVAILABLE.

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

and authority to execute and deliver this Agreement, to perform its respective

      party with respect to any Environmental, Health and Safety Laws in
      connection with the ownership of its properties or assets or the

      satisfaction of the issuing Governmental Authority or third party, or
      which could have a Material Adverse Effect on Proler.

           (d) Proler is in compliance with, and is not in breach of or default
      under any applicable writ, order, judgment, injunction, governmental
      communication or decree issued pursuant to the Environmental, Health and

acquisitions in the line of business in which MTLM is engaged and related
businesses hereafter acquired.  MTLM shall promptly provide Proler with a copy
of any  of MTLM's press releases.  Furthermore, MTLM shall not declare a stock
split, stock dividend or similar transaction.  In addition, MTLM will use

Governmental Authority to any such transactions.

its own advice as to the tax treatment of the transactions covered by this

limiting the foregoing, it is understood that any violation of the restrictions
set forth in the preceding sentence by any Manager of Proler or any of its
subsidiaries or affiliates or any investment banker or other advisor to any

Other Agreements, and each party who is a married individual shall cause his
spouse to execute all consents requested by MTLM to consummate the transactions

filed with the United States Federal Trade Commission (the "FTC") and the
United State Department of Justice (the "DOJ") the notification and report form
required for the transactions contemplated hereby and any supplemental
information requested in connection therewith pursuant to the HSR Act.  Any
such notification and report form and supplemental information will be in

Proler and the Members will furnish to the others such necessary information
and reasonable assistance as the others may request in connection with the
preparation of any filing or submission which is necessary under the HSR Act. 
Each of Proler, the Members and MTLM will keep each other apprised of the

affiliates to not, directly or indirectly, (i) solicit for employment by any
such person, its affiliates or anyone else, any employee or then currently

      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 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.

      Damages hereunder, MTLM shall promptly give written notice to the Members
      of such claim and the amount or the estimated amount of such claim, and
      the basis for such claim.  If the Members do not pay the amount of the
      claim for Indemnifiable Damages to MTLM within 10 days, then MTLM may
      exercise its respective rights under Section 8.4.

          (e) Notwithstanding anything to the contrary contained in this
      Section 8.1, the Members' liability for Indemnifiable Damages shall be
      limited as follows:

              (i) MTLM shall have no claim for Indemnifiable Damages unless
          and until all Indemnifiable Damages incurred by MTLM exceed an
          aggregate of $50,000, in which event the Members shall be liable
          for only such Indemnifiable Damages in excess of $50,000; provided,
          however, that the $50,000 deductible provided above shall not be
          applicable for any Indemnifiable Damages relating to Taxes; and

              (ii) the total amount of Indemnifiable Damages for which the
          Members shall be liable to MTLM shall not exceed the principal and
          interest due on the Purchase Notes.

      means, without duplication, the aggregate of all expenses, losses, costs,
      deficiencies, liabilities and damages (including, without limitation,
      reasonable related counsel and paralegal fees and expenses) incurred or
      suffered by the Members, 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 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 Members Indemnifiable Damages, the Members 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 Closing Date, notwithstanding any investigation at any time made by
      or on behalf of the Members, and upon expiration of such one year period,
      such representations and warranties shall expire, except for the
      representations contained in Sections 2.1, 2.2, 2.3 and 2.4 shall not
      expire, but shall continue indefinitely.  No claim for the recovery of
      Members Indemnifiable Damages may be asserted by the Members 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 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 Members believe they are entitled to a
      claim for any Indemnifiable Damages hereunder, the Members 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 contained in this
      Section 8.2, the Members shall have no claim for Indemnifiable Damages
      unless and until all Indemnifiable Damages incurred by the Members shall
      exceed an aggregate of $50,000, in which event MTLM shall be liable for 
      only such Indemnifiable Damages in excess of $50,000.

          (f) The remedies set forth in this Section 8.2 shall be the
      exclusive remedies of the Members under this Agreement.

          (c) If, prior to the expiration of the Notice of Contest Period, the
      Members shall notify MTLM in writing of an intention to dispute the claim

                              EMPLOYMENT AGREEMENT

     This Employment Agreement ("Agreement") is dated as of August 27, 1997, by
and between Metal Management, Inc., a Delaware corporation ("MTLM"), and
William T. Proler ("Employee").

     IT IS HEREBY AGREED:

     1. EMPLOYMENT.  On the terms and subject to the conditions set forth in
this Agreement, MTLM agrees to employ the Employee to perform such duties and
responsibilities as are consistent with such positions as may be assigned to
Employee, from time to time, by MTLM and are at least equivalent to those
duties and responsibilities performed by Employee as an employee of Proler
Southwest Inc. ("Proler Southwest").  Employee's duties hereunder shall be
performable for the Proler Southwest operations of MTLM only in the Houston,
Texas area, except that periodic trips to Proler Southwest's operations or
customers outside the Houston area or attending MTLM corporate meetings may be
required, and shall include, but not be limited to, participating in decisions
regarding finance, information systems, due diligence on financial and
operational aspects of acquisitions and the integration of acquisitions,
working with senior management of MTLM on budgets, contracts, scrap purchases
and personnel decisions for Proler Southwest.  For as long as Employee is so
employed, he will devote his full business time, energy and ability to his
duties, except for incidental attention to the management of his personal
affairs.

     2. TERM.  The term of employment under this Agreement shall commence on
the date hereof (the "Commencement Date") and shall continue for a period of
five (5) years thereafter (the "Employment Period"); provided, however, that on
each anniversary of the Commencement Date, the Employment Period shall be
automatically extended for an additional one (1) year (for an aggregate
remaining term of 5 years) unless at least sixty (60) days before any such
anniversary, either the Employee or MTLM, as the case may be, notifies the
other of its desire not to further extend the Employment Period; and provided,
further, that the Employment Period may terminate sooner upon the occurrence of
certain events as described in Sections 5, 6 and 7 hereof.  For purposes of
this Agreement, "Balance of the Term" shall mean the period beginning on the
date of termination of the Employment Period (the "Termination Date") and
ending on the date that the Employment Period would have ended pursuant to this
Section 2 due to lapse of time (assuming no further extensions of the
Employment Period beyond those already in effect as of the Termination Date),
without regard to Sections 5, 6 or 7 hereof.

     3. COMPENSATION.

        (a) Base Compensation.  The base compensation to be paid to Employee 
            for his services under this Agreement shall be $225,000 per year,
            payable in equal periodic installments in accordance with the usual
            payroll practices 

<PAGE>   2

            of MTLM, but no less frequently than monthly commencing on the date
            hereof. MTLM and the Employee agree that Employee's base
            compensation shall be subject to annual review for cost of living
            and merit factors, with any adjustments being mutually agreed
            upon.  The foregoing is hereafter referred to as Employee's "Base
            Compensation."

        (b) Bonuses.  The parties acknowledge and agree that on the 
            Commencement  Date, Proler Southwest shall pay Employee a bonus
            equal to twenty-five percent (25%) of Employee's base salary during
            the period from January 1, 1997 through the Commencement Date. 
            During the Employment Period, Employee shall earn a so-called
            "guaranteed bonus" in regard to each year of employment by MTLM
            equal to twenty-five percent (25%) of Employee's Base Compensation
            under Section 3(a) hereof during such year.  During the Employment
            Period, Employee shall also be eligible to receive a so-called
            "discretionary bonus" in regard to each year of employment by MTLM,
            in an amount to be determined by the Executive Committee of MTLM in
            consultation with William T. Proler based primarily upon the
            financial results of the Proler Southwest operating region during
            such year, provided that the discretionary bonus for Employee shall
            be determined in accordance with the bonus  standards and criteria
            then being used by the Executive Committee of MTLM to determine the
            discretionary bonuses for senior management officers of MTLM.

     4. FRINGE BENEFITS.  MTLM shall furnish Employee with accident and health
insurance and reimbursement of all documented reasonable and necessary
out-of-pocket expenses incurred by Employee on behalf of MTLM by reason of
Employee's duties hereunder.  Further, MTLM shall furnish Employee with all of
the additional fringe benefits made generally available by MTLM to its
executive officers recognizing that such fringe benefits may be changed from
time to time provided Employee will be deemed immediately eligible for any such
fringe benefits.  Employee shall be entitled to take five (5) weeks of paid
vacation per year, and shall be paid on all national and state holidays, during
the Employment Period.  Vacation allowances shall not be cumulative from year
to year.  MTLM shall include Employee as a covered person under MTLM's
directors and officers insurance policy.  MTLM shall furnish Employee with
appropriate office space, equipment, supplies, and such other facilities and
personnel as necessary or appropriate (de minimis use thereof by Employee for
personal reasons shall not be deemed a breach of this Agreement).  MTLM will
pay the Employee's dues in such societies and organizations as MTLM deems
appropriate, and will pay on behalf of Employee (or reimburse Employee for)
documented reasonable out-of-pocket expenses incurred by Employee in attending
conventions, seminars, trade shows and other business meetings and business
entertainment and promotional expenses.  MTLM shall permit Employee to continue
to use the automobile currently used by Employee as an employee of Proler
Southwest as of the Commencement Date and pay Employee an automobile allowance
of $500 per month.

                                      2

     5. DEATH OR PERMANENT DISABILITY.  If, during the Employment Period,
Employee dies (as confirmed by a certificate of death) or Employee is
permanently disabled such that, in the opinion of a physician selected by MTLM,
Employee is rendered incapable of performing the services contemplated under
this Agreement for a period of twelve (12) consecutive months by reason of
illness, accident, or other physical or mental disability ("Permanent
Disability"), this Agreement shall be deemed to be terminated as of the date of
such death or of the determination of Permanent Disability.  Notwithstanding
the foregoing, the payments hereunder shall continue to be paid to the Employee
or his estate, as the case may be, for the Balance of the Term.

     6. INVOLUNTARY TERMINATION.  Except in the case of termination for Cause
pursuant to Section 7 hereof, if MTLM terminates Employee's employment
hereunder without Employee's consent, all of Employee's benefits under this
Agreement shall cease immediately upon the date of such termination, provided
that Employee shall continue to be entitled to receive the compensation
provided in Section 3 hereof for the Balance of the Term.

     7. TERMINATION VOLUNTARY OR FOR CAUSE.

     In the event: (i)  Employee voluntarily terminates his employment
hereunder; or (ii) Employee's employment hereunder is terminated for Cause, all
of his benefits under this Agreement shall cease immediately upon the date of
such termination, provided that Employee shall be entitled to receive the
compensation provided in Section 3 hereof paid on a pro rata basis to the date
of such termination.

     TERMINATION FOR CAUSE.  Any of the following events shall be considered as
"Cause" for the immediate termination of the Employment Period by MTLM:

      (a)  final and non-appealable conviction of Employee for a 
           felony; or
     
      (b)  final and non-appealable conviction of Employee for 
           misappropriation by Employee of funds or property of 
           MTLM or the commission of other acts of dishonesty 
           relating to his employment; or
     
      (c)  willful breach or material neglect by Employee of 
           any of his material duties hereunder; or
     
      (d)  conduct on the part of Employee which is materially 
           adverse to any known interest of MTLM that continues 
           unabated, or uncured to the reasonable satisfaction 
           of Employer, after the expiration of 10 days 
           following receipt of written notice by Employee 
           from MTLM.

                                      3


<PAGE>   4

     Notwithstanding the foregoing, the Employee shall not be deemed to have
been terminated for Cause unless and until there shall have been delivered to
him a written termination notice signed by the Chairman of the Board of
Directors of MTLM.

     ACCELERATION OF PAYMENTS.

     For this Agreement, the following terms shall have the following meanings:

     "Good Reason" shall mean the occurrence of any of the following events
without Employee's express written consent:  (a) a reduction by MTLM of
Employee's compensation provided in Section 3 hereof; (b) any material breach
by MTLM of any provisions of this Agreement which is not cured by MTLM within
10 days following receipt by MTLM of written notice of such breach from
Employee; (c) a requirement by MTLM that Employee perform his duties outside
the Houston, Texas area, except that periodic trips to Proler Southwest
operations or customers outside Houston, Texas and periodic MTLM corporate
meetings outside Houston, Texas shall not be deemed to be a breach or (d) the
assignment of the Executive by MTLM without his consent to a position,
responsibility or duties of a material lesser status or degree of
responsibility than his position, responsibilities or duties as of the
Commencement Date.

     A "Change of Control" shall be deemed to have occurred if any "person" as
such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of
1934, as then in effect, other than:  (i) MTLM; (ii) any "person" who on the
date hereof is a director or officer of MTLM; or (iii) Albert A. Cozzi, Frank
J. Cozzi and Gregory P. Cozzi and their respective affiliates and heirs, is or
becomes the "beneficial owner" as defined in Rule 13d-3 under such Act,
directly or indirectly, of securities of MTLM representing 51% or more of the
combined voting power of MTLM's then outstanding securities on a fully diluted
basis.

     "Trigger Date" means the date on which a Triggering Event occurs.

     "Triggering Event" means any of:  (a) a Change of Control; (b) a
resignation of Employee as an employee of MTLM due to Good Reason; (c)
termination of the Employment Period under Section 5 hereof; or (d) involuntary
termination of the Employment Period, except in the case of termination for
Cause.

     Occurrence of Triggering Event.  Upon the occurrence of a Triggering
Event, Employee shall receive from MTLM a lump sum payment equal to the Base
Compensation provided under Section 3(a) hereof that otherwise would have been
payable to Employee for the Balance of the Term but for the occurrence of a
Triggering Event, plus any earned bonuses as set forth in Section 3(b) hereof
(determined on a pro rated basis in comparison to Employee's bonus, if any,
from the prior year) for the year in which the Triggering Event occurred.
Furthermore, any unvested stock options or unvested long term incentive plan
compensation shall immediately become vested and be exercisable for the 270
days following the date of the Triggering Event.

     Time of Payment.  All accelerated payments of Base Compensation, bonuses,
and long term incentive plan compensation due to Employee pursuant to this
Section shall be paid

promptly but in any event within thirty (30) days after the Trigger Date.  If
the full amount of such accelerated payments is not paid within five (5)
business days after the Trigger Date, such amounts shall be evidenced by a
promissory note from MTLM to Employee bearing interest at the rate of 12% per
annum from the Trigger Date until paid.

     8.  NON-COMPETITION.  In addition to any other obligations of Employee
under any other agreement with MTLM, in order to assure that MTLM will realize
the benefits of this Agreement and in consideration of the employment set forth
in this Agreement, Employee agrees that he shall not, during the Employment
Period and for a period of sixty (60) months from the Termination Date:

     (a) directly or indirectly, whether through an affiliate or otherwise, 
         alone or as a partner, joint venturer, member, officer, director,
         employee, consultant, agent, independent contractor, stockholder, or
         in any other capacity of any company or business, engage in any
         business activity in the States of Texas or Mississippi, which is
         directly or indirectly in competition with the business conducted by
         MTLM or any subsidiary or affiliate of MTLM on the Termination Date;
         provided, however; that, the beneficial ownership of less than 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 
         MTLM  or any subsidiary or affiliate of MTLM on the Termination Date
         to patronize any business directly or indirectly in competition with
         the business conducted by MTLM or any subsidiary or affiliate of MTLM
         on the Termination Date; (ii) canvass, solicit or accept from any
         person which is a customer of MTLM or any subsidiary or affiliate of
         MTLM on the Termination Date, any such competitive business, or (iii)
         request or advise any person which is a customer of MTLM or any
         subsidiary or affiliate of MTLM on the Termination Date to withdraw,
         curtail or cancel any  such customer's business with MTLM or any
         subsidiary or affiliate of MTLM on the Termination Date;

     (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 any of MTLM or any then subsidiary or
         affiliate of MTLM at or within six months prior to the Termination
         Date, or in any manner seek to induce any such person to leave his or
         her employment;

     (d) directly or indirectly, at any time following the Termination Date, 
         in any way utilize, disclose, copy, reproduce or retain in his
         possession any of MTLM's or any subsidiary's or affiliate's    
         proprietary rights or records, including, but not limited to, any of
         their customer or price lists.

     The Employee agrees and acknowledges that the restrictions contained in
this Section 8 are reasonable in scope and duration and are necessary to
protect MTLM after the Commencement Date.  If any provision of this Section 8
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 MTLM and upon breach of any provision of this Section,
MTLM 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 MTLM may have (including, without limitation, the right to seek
monetary damages).

     9. CONFIDENTIALITY OF INFORMATION; DUTY OF NON-DISCLOSURE.  The Employee 
acknowledges and agrees that his employment by MTLM under this Agreement
necessarily involves his understanding of and access to certain trade secrets
and confidential information pertaining to the business of MTLM or any
subsidiary or affiliate of MTLM. Accordingly, the Employee agrees that after
the date of this Agreement at all times he will not, directly or indirectly,
without the prior written consent of MTLM, disclose to or use for the benefit
of any person, corporation or other entity, or for himself any and all files,
trade secrets or other confidential information concerning the internal affairs
of MTLM or any subsidiary or affiliate of MTLM, including, but not limited to,
confidential information pertaining to clients, services, products, earnings,
finances, operations, methods or other activities; provided, however, that the
foregoing shall not apply to information which is of public record or is
generally known, disclosed or available to the general public or the industry
generally.  Further, the Employee agrees that he shall not, directly or
indirectly, remove or retain, without the express prior written consent of
MTLM, and upon termination of this Agreement for any reason shall return to
MTLM, any confidential figures, calculations, letters, papers, records,
computer disks, computer print-outs, lists, documents, instruments, drawings,
designs, programs, brochures, sales literature, or any copies thereof, or any
information or instruments derived therefrom, or any other similar information
of any type or description, however such information might be obtained or
recorded, arising out of or in any way relating to the business of MTLM or any
subsidiary or affiliate of MTLM or obtained as a result of his employment by
MTLM or any subsidiary or affiliate of MTLM.  The Employee acknowledges that
all of the foregoing are proprietary information, and are the exclusive
property of MTLM.  The covenants contained in this Section 9 shall survive
the termination of this Agreement.

     10. GOODWILL.  MTLM has invested substantial time and money in the
development of its products, services, territories, advertising and marketing
thereof, soliciting clients and creating goodwill.  By accepting employment
with MTLM, the Employee acknowledges that the customers are the customers of
MTLM and its subsidiaries and affiliates, and that any goodwill created by
the Employee belongs to and shall inure to the benefit of MTLM.

     11. SUCCESSOR COMPANIES.  This Agreement shall be binding upon and inure 
to  the benefit of the successors and assigns of MTLM, whether by merger, sale 
of assets or otherwise.

     12. NOTICES.  Any notice or request to be given hereunder to either party 
hereto shall be deemed effective only if in writing and either (1) delivered
personally to Employee (in the case of a notice to Employee) or to the
President of MTLM, or (2) sent by certified or registered mail, postage
prepaid, to the addresses set forth on the signature page hereof or to such
other address as either party may hereafter specify to the other by notice 
similarly served.

     13. ASSIGNMENT.  This Agreement and the rights and obligations of the 
parties hereto shall bind and inure to the benefit of each of the parties
hereto, and shall also bind and inure to the benefit of Employee's heirs and
legal representatives and any successor or successors of MTLM by merger or
consolidation and any assignee of all or substantially all of MTLM's business
and properties; except as to any such successor or assignee of MTLM, neither
this Agreement nor any duties, rights or benefits hereunder may be assigned by 
MTLM or by Employee without the express written consent of Employee or MTLM, 
as the case may be.

     14. GOVERNING LAW.  This Agreement shall be construed and enforced in 
accordance with the laws of the State of Texas without reference to its 
choice-of-law principles.

     15. MODIFICATION.  No modification or waiver of any provision hereof shall 
be made unless it be in writing and signed by both of the parties hereto.

     16. SCOPE OF AGREEMENT.  This Agreement constitutes the whole of the 
agreement between the parties on the subject matter, superseding all prior oral
and written conversations, negotiations, understandings, and agreements in 
effect as of the date of this Agreement.

     17. SEVERABILITY.  To the extent that any provision of this Agreement 
may be deemed or determined to unenforceable for any reason, such
unenforceability shall not impair or affect any other provision, and this
Agreement shall be interpreted so as to most fully give effect to its terms and
still be enforceable.
