ITEM 5.  OTHER EVENTS

         On March 31, 1998, Metal Management, Inc., a Delaware corporation (the
"Company") and its subsidiaries entered into a Credit Agreement (the "Senior
Credit Facility") with BT Commercial Corporation, as agent for the lenders (the
"Agent"), and certain commercial lending institutions. The Senior Credit
Facility provides for a revolving credit and letter of credit facility of
$200,000,000 terminating on March 31, 2001. The Senior Credit Facility bears
interest at a floating rate per annum equal to (at the Company's option): (i)
1.75% over LIBOR or (ii) 0.5% over Bankers Trust Company's prime rate as in
effect from time to time. The Senior Credit Facility is available for working
capital and general corporate purposes,including acquisitions. The Company and
its subsidiaries are required under the Senior Credit Facility to pay the Agent
certain fees and expenses which include an unused line fee on a monthly basis.
The obligations of the Company under the Senior Credit Facility are secured by a
security interest in substantially all of the assets and properties of the
Company and its subsidiaries. Availability of loans and letters of credit under
the Senior Credit Facility is limited to a borrowing base constituted of
eligible accounts receivable and inventory and a fixed asset sublimit that
amortizes on a quarterly basis.

         The Senior Credit Facility contains a number of covenants that, among
other things, restrict the ability of the Company to dispose of assets, incur
additional indebtedness, pay dividends or make distributions, create liens on
assets, enter into sale and leaseback transactions, make investments, loans or
advances, make acquisitions, engage in mergers or consolidations and form
subsidiaries and otherwise restrict certain corporate activities. In addition,
the Company is required to comply with specified financial ratios and tests.

         The Senior Credit Facility contains various events of default,
including defaults relating to payments, breaches of representations, warranties
and covenants, certain events of bankruptcy and insolvency, defaults on certain
other indebtedness, certain liens and encumbrances on assets and certain changes
of control of the Company.

         Subject to the terms and conditions set forth in this Credit Agreement,
and in reliance on the representations and warranties of the Borrowers set forth
herein, on and after the Closing Date and to but excluding the Expiration Date,
each Lender severally agrees to make loans and advances to the Borrowers on a
joint and several basis (each a "REVOLVING LOAN") in an amount not to exceed at
any time its Proportionate Share of the lesser at such time of (a) the Line of
Credit and (b) the Borrowing Base MINUS, in each case, the then outstanding
Letter of Credit Obligations. The Revolving Loans shall be evidenced by a
Revolving Note dated as of the Closing Date, issued to the Agent and executed by
each of the Borrowers in the amount of the Line of Credit.

         2.2      BORROWING OF REVOLVING LOANS.

         Revolving Loans may be made available to the Funds Admini-

strator for the account of the Borrowers directly by the Lenders ("LENDER
ADVANCES") or, in the circumstances described in SECTION 2.2(b), from the Agent
acting on behalf of the Lenders ("AGENT ADVANCES").

                  (a) LENDER ADVANCES. Subject to the determination by the Agent
         and the Lenders that the conditions for borrowing contained in SECTION
         5.2 are satisfied, upon receipt of a Notice of Borrowing from the Funds
         Administrator received by the Agent before 12:00 noon Chicago time on a
         Business Day, Lender Advances of Revolving Loans shall be made to the
         extent



                                      -23-

<PAGE>   30

of each Lender's Proportionate Share of the requested Borrowing.

                  (b) AGENT ADVANCES. The Agent is authorized by the Lenders,
         but is not obligated, to make Agent Advances upon a receipt of any
         Notice of Borrowing received by the Agent before 3:00 P.M. Chicago time
         on a Business Day. Agent Advances shall be subject to periodic
         settlement with the Lenders under SECTION 2.4. Agent Advances may be
         made only in the following circumstances:

                             (i) NORMAL COURSE AGENT ADVANCES. For
                  administrative convenience, the Agent may, but is not
                  obligated, to make Agent Advances up to the amount available
                  for borrowing under SECTION 2.1 in reliance upon the actual or
                  deemed representations of the Borrowers under SECTION 5.2 that
                  the conditions for borrowing are satisfied.

                            (ii) OTHER AGENT ADVANCES. When the conditions for
                  borrowing under SECTION 5.2 cannot be fulfilled, and
                  notwithstanding the Borrowing Base limitation of SECTION 2.1,
                  the Agent may, but is not obligated, to continue to make Agent
                  Advances for seven (7) Business Days or until sooner
                  instructed by the Majority Lenders to cease, in an aggregate
                  amount at any time not to exceed $5,000,000.

                  (c)      DISBURSEMENT OF REVOLVING LOANS.  The proceeds of
         Revolving Loans shall be transmitted:  (x) in the circum-

         stances described in SECTION 3.5, by the Agent directly to the Issuing
         Bank, and (y) in all other circumstances, by the Agent or Lenders, as
         the case may be, to the Disbursement Account.

                  (d) NOTICES OF BORROWING. Notices of Borrowing may be given
         under this Section by telephone or facsimile transmission, and, if by
         telephone, promptly shall be confirmed in writing. The Funds
         Administrator shall specify in each Notice of Borrowing whether the
         conditions for the requested Borrowing are satisfied. The Borrowers may
         request one or more Borrowings of Revolving Loans constituting Prime
         Rate Loans on the same Business Day. Each Notice of Borrowing for LIBOR
         Rate Loans shall be given not later than noon Chicago time on the third
         Business Day prior to the proposed Borrowing. Each Notice of Borrowing
         shall, unless otherwise specifically provided herein, consist entirely
         of Revolving Loans of the same Type and, if such Borrowing is to
         consist of LIBOR Rate Loans, shall be in an aggregate amount of not
         less than $1,000,000 or an integral multiple of $100,000 in excess
         thereof. The right of the Borrowers to choose LIBOR Rate Loans is
         subject to the provisions of SECTION 4.13. Once given, a Notice of
         Borrowing is irrevocable and binding on the 



                                      -24-

<PAGE>   31

         Borrowers. The Funds Administrator shall provide to the Agent a list,
         with specimen signatures, of officers and other Persons, if any,
         authorized to request Revolving Loans. The Agent is entitled to rely
         upon such list until it is replaced by the Funds Administrator.

         2.3      NOTICE OF REQUEST FOR LENDER ADVANCES.

         Subject to the last sentence of this Section, the Agent shall give each
Lender prompt notice by telephone or facsimile transmission of a Notice of
Borrowing that is received pursuant to SECTION 2.2(a) and is to be satisfied by
Lender Advances. No later than 3:00 P.M. Chicago time on the date of receipt of
such notice, each Lender shall make available for the account of its Applicable
Lending Office to the Agent at the Agent's address for deposit into the
Disbursement Account, its Proportionate Share of such Borrowing in immediately
available funds. Unless the Agent receives contrary written notice prior to any
such Borrowing, it is entitled to assume that each Lender will make available
its Proportionate Share of the Borrowing and in reliance upon that assumption,
but without any obligation to do so, may advance such Proportionate Share on
behalf of the Lender, without the necessity of giving daily notice to each
Lender of the receipt of a Notice of Borrowing.

         2.4      PERIODIC SETTLEMENT OF AGENT ADVANCES; INTEREST AND FEES;
                  STATEMENTS.

                  (a) THE SETTLEMENT DATE; ALLOCATION OF INTEREST AND FEES. The
         amount of each Lender's Proportionate Share of Revolving Loans shall be
         computed weekly (or more frequently in the Agent's discretion) and
         shall be adjusted upward or downward based on all Revolving Loans
         (including Agent Advances) and repayments received by the Agent as of
         5:00 P.M. Chicago time on the last Business Day of the period specified
         by the Agent (such date, the "SETTLEMENT DATE").

                  (b) SUMMARY STATEMENTS; SETTLEMENTS. The Agent shall deliver
         to each of the Lenders promptly after the Settlement Date a summary
         statement of the account of outstanding Revolving Loans (including
         Agent Advances) for the period, the amount of repayments received for
         the period, and the amount allocated to each Lender of the interest and
         Unused Line Fee for the period. After application of payments under
         SECTION 4.11, as reflected on the summary statement, (i) the Agent
         shall transfer to each Lender its allocated share of interest and
         Unused Line Fee, and its Proportionate Share of repayments received by
         the Agent in respect of the period covered by such summary statement;
         and (ii) each Lender shall transfer to the Agent, or the Agent shall
         transfer to each Lender, such amounts as are necessary to insure that,
         after giving effect to all such transfers, the amount of Revolving
         Loans made by



                                      -25-

<PAGE>   32

         each Lender shall be equal to such Lender's Proportionate Share of the
         aggregate amount of Revolving Loans outstanding as of such Settlement
         Date. If the summary statement requires transfers to be made to the
         Agent by the Lenders and is received by the Lenders prior to 12:00 noon
         Chicago time on a Business Day, such transfers shall be made in
         immediately available funds no later than 3:00 P.M. Chicago time that
         day; and, if received after 12:00 noon Chicago time, then no later than
         3:00 P.M. Chicago time on the next Business Day. The obligation of each
         Lender to transfer such funds is irrevocable, unconditional and without
         recourse to or warranty by the Agent.

                  (c) DISTRIBUTION OF INTEREST AND UNUSED LINE FEES. Interest on
         the Revolving Loans (including Agent Advances) and the Unused Line Fee
         shall be allocated by the Agent to each Lender (i) in the case of
         interest, in accordance with the Revolving Loans actually advanced by
         and repaid to such Lender and (ii) in the case of the Unused Line Fee,
         in accordance with the Proportionate Share of such Lender. Interest
         shall accrue from and including the date Revolving Loans are advanced
         and to but excluding the date such Revolving Loans are either repaid by
         the Borrowers or, if later, actually settled under this Section.
         Promptly after the end of each month, the Agent shall distribute to
         each Lender its portion, allocated as provided above, of the interest
         and Unused Line Fee which has been received by the Agent during such
         month.

         2.5      SHARING OF PAYMENTS.

         If any Lender shall obtain any payment (whether made voluntarily or
involuntarily, or through the exercise of any right of set-off, or otherwise) on
account of the Revolving Loans made by it or its participations in the Letter of
Credit Obligations in excess of its Proportionate Share of payments on account
of the Revolving Loans or Letter of Credit Obligations obtained by all the
Lenders, such Lender shall forthwith purchase from the other Lenders such
participations in the Revolving Loans made by them or in their participation in
Letters of Credit as shall be necessary to cause such purchasing Lender to share
the excess payment ratably with each of them; PROVIDED, THAT if all or any
portion of such excess payment is thereafter recovered from such purchasing
Lender, such purchase from each other Lender shall be rescinded and each such
other Lender shall repay to the purchasing Lender the purchase price to the
extent of such recovery, together with an amount equal to such other Lender's
ratable share (according to the proportion of (i) the amount of such Lender's
required repayment to (ii) the total amount so recovered from the purchasing
Lender) of any interest or other amount paid or payable by the purchasing Lender
in respect to the total amount so recovered. The Borrowers agree that any Lender
so purchasing a participation from another Lender



                                      -26-

<PAGE>   33

pursuant to this SECTION 2.5, to the fullest extent permitted by law, may
exercise all of its rights of payment (including the right of set-off) with
respect to such participation as fully as if such Lender were the direct
creditor of the Borrowers in the amount of such participation.

         2.6      DEFAULTING LENDERS.

                  (a) A Lender who fails to pay the Agent its Proportionate
         Share of any Revolving Loans (including Agent Advances) made available
         by the Agent on such Lender's behalf, or who fails to pay any other
         amounts owing by it hereunder to the Agent, is a "DEFAULTING LENDER."
         The Agent is entitled to recover from such Defaulting Lender all such
         amounts owing by such Defaulting Lender on demand. If the Defaulting
         Lender does not pay such amounts on the Agent's demand, the Agent shall
         promptly notify the Funds Administrator and the Borrowers shall pay
         such amounts to the Agent (to the extent the Agent has made such
         amounts available to or for the account of the Borrowers) within five
         (5) Business Days of the receipt by the Funds Administrator of such
         notice. In addition, the Defaulting Lender or the Borrowers shall pay
         to the Agent for its own account interest on such amount for each day
         from the date it was made available by the Agent to the Borrowers to
         the date it is recovered by the Agent at a rate per annum equal to (x)
         the overnight Federal Funds Rate if paid by the Defaulting Lender, or
         (y) the then applicable rate of interest calculated under SECTION 4.1,
         if paid by the Borrowers; plus, in each case, the Expenses and losses,
         if any, incurred as a result of the Defaulting Lender's failure to
         perform its obligations. Nothing herein shall be deemed to relieve any
         Lender of its obligation to fulfill its commitments hereunder or to
         prejudice any rights which the Borrowers may have against any Lender as
         a result of any default by such Lender hereunder, including, without
         limitation, the right of the Borrowers to seek reimbursement from any
         Defaulting Lender for any amounts paid by the Borrowers under CLAUSE
         (y) above on account of such Defaulting Lender's default.

                  (b) The failure of any Lender to fund its Proportionate Share
         of a Revolving Loan shall not relieve any other Lender of its
         obligation to fund its Proportionate Share of a Revolving Loan.
         Conversely, no Lender shall be responsible for the failure of another
         Lender to fund its Proportionate Share of a Revolving Loan.

                  (c) The Agent shall not be obligated to transfer to a
         Defaulting Lender any payment made by the Borrowers to the Agent for
         the Defaulting Lender's benefit; nor shall a Defaulting Lender be
         entitled to the sharing of any payment



                                      -27-

<PAGE>   34

         hereunder. Amounts payable to a Defaulting Lender shall instead be paid
         to or retained by the Agent. The Agent may hold and, in its discretion,
         re-lend to the Borrowers the amount of all such payments received by it
         for the account of such Lender. For purposes of voting or consenting to
         matters with respect to the Credit Documents and determining
         Proportionate Shares, such Defaulting Lender shall be deemed not to be
         a "LENDER" and such Lender's Commitment shall be deemed to be zero
         (-0-). This section shall remain effective with respect to such Lender
         until (x) the Obligations shall have been declared or shall have become
         immediately due and payable or (y) the Majority Lenders, the Agent and
         the Borrowers shall have waived such Lender's default in writing. The
         operation of this Section shall not be construed to increase or
         otherwise affect the Commitment of any Lender, or relieve or excuse the
         performance by the Borrowers of their respective duties and obligations
         hereunder.

         2.7      ALLOCATION OF REVOLVING LOANS AND EXPENSES.

                  (a) The Borrowers maintain an integrated cash management
         system reflecting their interdependence on one another and the mutual
         benefits shared among them as a result of their respective operations.
         In order to efficiently fund and operate their respective businesses
         and minimize the number of Borrowings which they will make under this
         Credit Agreement and thereby reduce the administrative costs and record
         keeping required in connection therewith, including the necessity to
         enter into and maintain separately identified and monitored borrowing
         facilities, the Borrowers have requested, and the Agent and the Lenders
         have agreed that, subject to SECTION 11.16, (i) all Revolving Loans
         will be advanced to and for the account of the Borrowers on a joint and
         several basis to the Disbursement Account and (ii) all Letters of
         Credit will be issued pursuant to an application therefor executed by
         the Funds Administrator on behalf and for the account of the Borrower
         or Borrowers specified by the Funds Administrator in such application.
         Each of the Borrowers hereby acknowledges that it will be receiving a
         direct benefit from each Revolving Loan made and each Letter of Credit
         issued pursuant to this Credit Agreement.

                  (b) In order to track more precisely the respective recipients
         of the proceeds of each Revolving Loan and the Borrower receiving the
         primary benefit from the issuance of each Letter of Credit, and to
         assist the Funds Administrator, the Borrowers, the Agent and the
         Lenders in administering the Revolving Loans and the Letters of Credit,
         each of the Borrowers has agreed with the Agent and the Lenders to
         cause the Funds Administrator to establish and maintain, and the Funds
         Administrator hereby agrees to establish and maintain,



                                      -28-

<PAGE>   35

         accounts with respect to each Borrower (each Borrower's "ALLOCATION
         ACCOUNT") in which the Funds Administrator shall record its good faith
         allocation to each of the Borrowers of (w) the proceeds, if any, of
         each Revolving Loan received by or for the account of such Borrower,
         (x) payments made to the Agent on account of the Obligations of such
         Borrower, (y) the aggregate face amount of all outstanding Letters of
         Credit covering goods which such Borrower will receive and (z) all
         previously unallocated Expenses.

                  (c) As soon as available, but not later than fifteen (15)
         Business Days after the last Business Day of each month ending after
         the Closing Date, the Funds Administrator shall
         deliver to the Agent and each Borrower a report prepared by or under
         the supervision of the chief financial officer of the Funds
         Administrator, and certified by such officer, setting forth with
         respect to each Borrower the balance of the Allocation Account of such
         Borrower as of the end of, and all activity occurring in such

         such monthly statement shall be final, conclusive and binding on the
         respective Borrowers.


                          ARTICLE 3. LETTERS OF CREDIT.

         3.1      ISSUANCE OF LETTERS OF CREDIT.

         Subject to the terms and conditions hereof and in reliance on the
representations and warranties of the Borrowers set forth herein, the Agent
shall cause the Issuing Bank to issue Letters of Credit hereunder at the request
of the Funds Administrator and for its account, as more specifically described
below. The Agent shall not be obligated to cause the Issuing Bank to issue any
Letter of Credit if:

                  (a) issuance of the requested Letter of Credit (i) would cause
         the Letter of Credit Obligations then outstanding to exceed $50,000,000
         or (ii) would cause the sum of the Revolving Loans PLUS the Letter of
         Credit Obligations then outstanding to exceed the lesser of (x) the
         Line of Credit and (y) the Borrowing Base, in each case then in effect;
         or

                  (b) issuance of the Letter of Credit is enjoined, restrained
         or prohibited by any Governmental Authority, Requirement of Law or any
         request or directive of any Governmental Authority (whether or not
         having the force of law) or would impose upon the Agent or the Issuing
         Bank any material restriction, reserve, capital requirement, loss, cost
         or expense (for which the Agent or the Issuing Bank is not



                                      -29-

         otherwise compensated) not in effect or known as of the Closing Date.

         3.2      TERMS OF LETTERS OF CREDIT.

         The proposed amount, terms and conditions, and form of each Letter of
Credit (and of any drafts or acceptances thereunder) shall be subject to
approval by the Issuing Bank. The term of each standby Letter of Credit shall
not exceed 360 days, but may be subject to annual renewal. The term of each
documentary Letter of Credit shall not exceed 120 days. No Letter of Credit
shall have an expiry date later than five (5) Business Days prior to the 
Expiration Date.

         3.3      NOTICE OF ISSUANCE.

         A request for issuance of a Letter of Credit (a "LETTER OF CREDIT
REQUEST") may be given in writing or electronically and, if given electronically
and if requested by the Agent, promptly shall be confirmed in writing. A Letter
of Credit Request must be received by the Agent no later than 1:00 P.M. Chicago
time at least three (3) Business Days (or such shorter period as may be agreed
to by the Issuing Bank) in advance of the proposed date of issuance.

         3.4      LENDERS' PARTICIPATION.

         Immediately upon issuance, amendment or extension of any Letter of
Credit, each Lender shall be deemed to have irrevocably and unconditionally
purchased and received from the Issuing Bank, without recourse or warranty, an
undivided interest and participation in all rights and obligations under such
Letter of Credit (other than fees and other amounts owing to the Issuing Bank)
in accordance with such Lender's Proportionate Share.

         3.5      PAYMENTS OF AMOUNTS DRAWN UNDER LETTERS OF CREDIT.

         The Agent shall notify the Funds Administrator of the receipt by the
Agent of notice from the Issuing Bank of a draft or other presentation for
payment or drawing under a Letter of Credit not later than 11:00 A.M. Chicago
time on the Business Day immediately prior to the date on which the Issuing Bank
intends to honor such drawing. Unless the procedures set forth in SECTION 9.2(c)
shall be applicable, the Funds Administrator shall be deemed to have
concurrently given a Notice of Borrowing to the Agent to make a Revolving Loan
in the amount of and at the time of such drawing (which Revolving Loan shall be
a Prime Rate Loan), the proceeds of which shall be applied directly by the Agent
to reimburse the Issuing Bank for the amount of such drawing.

         3.6      PAYMENT BY LENDERS.

         If a Revolving Loan is not made in an amount sufficient to reimburse
the Issuing Bank in full for the amount of any draw under a Letter of Credit,
the Agent shall promptly notify each Lender of the unreimbursed amount of such
drawing and of such Lender's respective participation therein. Each Lender shall
make available to the Agent, for the account of the Issuing Bank, the amount of
its participation in immediately available funds not later than 1:00 P.M.
Chicago time on the next Business Day after such Lender receives notice from the
Agent of the amount of such Lender's participation in such unreimbursed amount.
If any Lender fails to make available to the Agent the amount of such Lender's
participation, the Issuing Bank shall be entitled to recover such amount on
demand from such Lender together with interest at the Federal Funds Rate for the
first three Business Days and thereafter at the Prime Lending Rate. For each
Letter of Credit, the Agent shall promptly distribute to each Lender which has
funded the amount of its participation its Proportionate Share of all payments
subsequently received by the Agent from the Borrowers in reimbursement of
honored drawings.

         3.7      OBLIGATIONS ABSOLUTE.

         The joint and several obligations of the Borrowers to reimburse the
Lenders under SECTION 3.5 hereof shall be unconditional and irrevocable and
shall be paid strictly in accordance with the terms of this Credit Agreement
under all circumstances including, without limitation, upon the occurrence and
during the continuance of an Event of Default.

         3.8      AGENT'S EXECUTION OF APPLICATIONS AND OTHER ISSUING BANK
                  DOCUMENTATION; RELIANCE ON CREDIT AGREEMENT BY ISSUING
                  BANK.

         The Agent shall be authorized to execute, deliver and perform on behalf
of the Lenders such letter of credit applications, shipping indemnities, letter
of credit modifications and consents and other undertakings for the benefit of
the Issuing Bank as may be reasonably necessary or appropriate in connection
with the issuance or modification of Letters of Credit requested by the
Borrowers hereunder. The Lenders, the Agent, the Borrowers and the Funds
Administrator all expressly agree that the terms of this ARTICLE 3 and various
other provisions of this Credit Agreement identifying the Issuing Bank are also
intended to benefit the Issuing Bank and the Issuing Bank shall be entitled to
enforce the provisions hereof which are for its benefit.

                  (a) Interest on the unpaid principal amount of Revolving Loans
         which are Prime Rate Loans shall be payable monthly in arrears, on the
         first Business Day of each month, at an interest rate per annum equal
         to the Prime Lending Rate PLUS one-half of one percent (0.5%)
         calculated on the unpaid principal amount of Revolving Loans at the
         close of business each day during the immediately preceding month. The
         rate hereunder shall change each day the Prime Lending Rate changes.

                  (b) Interest on the unpaid principal amount of Revolving Loans
         which are LIBOR Rate Loans shall be payable on the earliest to occur of
         (i) the last day of each Interest Period with respect to such LIBOR
         Rate Loans, (ii) ninety (90) days following the commencement of the
         applicable Interest Period for such LIBOR Rate Loans, (iii) the date of
         conversion of such LIBOR Rate Loans (or a portion thereof) to a Prime
         Rate Loan (on the portion so converted) and (iv) the maturity of such
         LIBOR Rate Loans, at an interest rate per annum equal during the
         Interest Period for such LIBOR Rate Loans to the LIBOR Rate for the
         Interest Period in effect for such LIBOR Rate Loans PLUS one and
         three-quarters percent (1.75%). After maturity of such LIBOR Rate Loans
         (whether by acceleration or otherwise), interest shall be payable upon
         demand. The Agent upon determining the LIBOR Rate for any Interest
         Period shall promptly notify the Funds Administrator and the Lenders by
         telephone (confirmed promptly in writing) or in writing thereof. Each
         determination by the Agent of an interest rate hereunder shall be
         conclusive and binding for all purposes, absent demonstrable error.

                  (c) Notwithstanding the provisions of SECTION 4.1(b), the
         Borrowers shall pay to each Lender, so long as and to the extent such
         Lender shall be required under regulations of the Board of Governors of
         the Federal Reserve System to maintain reserves with respect to
         liabilities or assets consisting of or including Eurocurrency
         Liabilities, additional interest on the unpaid principal amount of each
         Revolving Loan comprised of LIBOR Rate Loans of such Lender, from the
         date of such LIBOR Rate Loan until such principal amount is paid in
         full, at an interest rate per annum equal at all times to the remainder
         obtained by subtracting (i) the LIBOR Rate for the applicable Interest
         Period for such LIBOR Rate Loan from (ii) the rate obtained by dividing
         such LIBOR Rate by a percentage equal to 1 MINUS the stated maximum
         rate (stated as a decimal) applicable two (2) Business Days before the
         first day of such Interest Period of all reserves, if any, required to
         be maintained against "EUROCURRENCY LIABILITIES" as specified in
         Regulation D (or against any other category of liabilities 



                                      -32-

          which includes deposits by reference to which the interest rate on
          LIBOR Rate Loans is determined or any category of extensions of credit
          or other assets which includes loans by a non-United States office of
          any Lender to United States residents) having a term equal to the
          Interest Period applicable to such LIBOR Rate Loan. Such Lender shall
          as soon as practicable provide notice to the Agent and the Funds
          Administrator of any such additional interest arising in connection
          with such LIBOR Rate Loan, which notice shall be conclusive and
          binding, absent demonstrable error.

         4.2      UNUSED LINE FEE.

         The Borrowers shall pay to the Agent, for the ratable benefit of the
Lenders, a non-refundable fee (the "UNUSED LINE FEE") equal to three-eighths of
one percent (0.375%) per annum of the unused portion of the Line of Credit (with
any outstanding Letters of Credit constituting usage of the Line of Credit). The
Unused Line Fee shall accrue daily from the Closing Date until the Expiration
Date, and shall be due and payable monthly in arrears, on the first Business Day
of each month and on the Expiration Date.

         4.3      LETTER OF CREDIT FEES.

                  (a) The Agent, for the ratable benefit of the Lenders, shall

         Business Day of each month, a fee (the "LETTER OF CREDIT FEE"), in an
         amount equal to one and three-quarters percent (1.75%) per annum of the
         daily weighted average undrawn amount of Letters of Credit outstanding
         during the immediately preceding month. In addition, the Agent, for its
         own account, shall be entitled to charge to the account of the
         Borrowers on the date of issuance of any standby Letter of Credit, a
         facing fee equal to one-half of one percent (0.50%) on the initial face
         amount of each such standby Letter of Credit (the "L/C FACING FEE").

                  (b) The Agent shall also be entitled to charge to the account
         of the Borrowers, as and when incurred by the Agent or any Lender, the
         customary charges, fees, costs and expenses charged to the Agent or any
         Lender for the Borrower's account by any Issuing Bank (the "ISSUING
         BANK FEES") in connection with the issuance, transfer, drawing,
         amendment or negotiation of any Letters of Credit by the Issuing Bank.
         Each determination by the Agent of Letter of Credit Fees, L/C Facing
         Fees, Issuing Bank Fees and other fees, costs and expenses charged
         under this Section shall be conclusive and binding for all purposes,

                  DEFAULT.

         From the date of occurrence of an Event of Default (after giving effect
to any applicable grace period) until the earlier of the date upon which (i) all
Obligations shall have been paid and satisfied in full or (ii) such Event of
Default shall have been cured or waived, interest on the Revolving Loans and
Letter of Credit Fees on Letter of Credit Obligations shall each be payable on
demand at a rate per annum equal to, with respect to the Revolving Loans, the 
rate in effect under SECTION 4.1, PLUS two percent (2%), and with respect to the
Letter of Credit Obligations, the rate at which Letter of Credit Fees are
charged pursuant to the first sentence of SECTION 4.3(a), PLUS two percent (2%).

         4.5      COLLATERAL MONITORING FEE.

         The Borrowers shall pay to the Agent, for its own account, a
non-refundable annual collateral monitoring fee (the "COLLATERAL MONITORING

earned and payable on the Closing Date and on each anniversary thereof.

         4.6      EXPENSES.

                  COMMITMENTS.

                  (a) Except during the period described in SECTION 2.2(b)(ii),
         the aggregate outstanding principal amount of Revolving Loans PLUS
         Letter of Credit Obligations at any time in excess of the lesser at
         such time of (i) the Line of Credit and (ii) the Borrowing Base, shall
         be immediately due and payable without the necessity of any demand.

                  (b) On the Expiration Date, the Commitment of each Lender
         shall automatically reduce to zero (-0-).

                  (c) The Borrowers may reduce or terminate the Line of Credit
         in whole, or in part at any time and from time to time; PROVIDED, that
         each such reduction must be in an amount not less than $5,000,000 (and
         in increments of $1,000,000 in excess thereof). Once reduced, no
         portion of the Line of Credit may be reinstated. If the Borrowers seek
         to reduce the Line of Credit to less than $25,000,000, then the Line of
         Credit shall be automatically and permanently reduced to zero ($0).

         4.8      MAINTENANCE OF LOAN ACCOUNT; STATEMENTS OF ACCOUNT.

         The Agent shall maintain an account on its books in the name of the
Borrowers (the "LOAN ACCOUNT") in which the Borrowers will be charged with all
loans and advances made by the Lenders to the Borrowers or for the account of
the Borrowers, including the Revolving Loans and all Letter of Credit
Obligations, the Fees, the Expenses and any other Obligations, as and when such
payments become due. The Loan Account will be credited with all payments

including all amounts received in the BT Account from the Collection Banks.
After the end of each month, the Agent shall send the Funds Administrator a
monthly statement accounting for the charges, loans, advances and other
transactions occurring among and between the Agent, the Lenders and the
Borrowers during that month, PROVIDED, THAT the failure of the Agent to send
such statement to the Funds Administrator shall not relieve the Borrowers of any
Obligations. Absent demonstrable error, each monthly statement shall be an
account stated and shall be final, conclusive and binding on the Borrowers.

         4.9      PAYMENT PROCEDURES.

         Payments of Fees, principal of and interest on the Revolving Loans and
Expenses payable to the Agent or any Lender shall be made in each case not later
than 2:00 P.M. Chicago time on the day when due, in immediately available
dollars, to the offices of the Agent, at the address set forth in SECTION 11.7,
or as the Agent may otherwise direct the Funds Administrator. The Borrowers
hereby authorize the Agent to charge the Loan Account with the amount of all
payments to be made hereunder and under the other Credit Documents, including
all Fees and Expenses, as and when such payments become due. The joint and
several obligations of the Borrowers to the Lenders with respect to such
payments shall be discharged by making such payments to the Agent pursuant to
this Section or by the charging of the Loan Account by the Agent.

         4.10     COLLECTION OF ACCOUNTS.

         Until instructed otherwise by the Agent, each Borrower shall be
entitled to receive Collections directly from account debtors in accordance with
its historical practices. On or prior to the Closing Date, each Borrower, the
Agent and financial institutions selected by such Borrower and reasonably
acceptable to the Agent (the "COLLECTION BANKS") shall enter into agreements in
form and substance satisfactory to Agent (the "DEPOSITARY ACCOUNT AGREEMENTS"),
which among other things shall provide for the opening of an account for the
deposit of Collections (a "COLLECTION ACCOUNT") at a Collection Bank. All
Collections and other amounts received by each Borrower from any account debtor,
in addition to all other cash received in respect of any other Collateral, shall
upon receipt be deposited into a Collection Account. Termination of such
arrangements shall also be subject to approval by the



                                      -35-
<PAGE>   42

Agent. Upon the terms and subject to the conditions set forth in the Depositary
Account Agreements, all available amounts held in each Collection Account shall
be wired each Business Day into an account (the "BT ACCOUNT") maintained by the
Agent at Bankers Trust Company. Amounts received in the BT Account from the
Collection Banks shall be credited to the Loan Account and distributed and
applied as set forth in SECTION 4.11.

         4.11     DISTRIBUTION AND APPLICATION OF COLLECTIONS AND OTHER
                  AMOUNTS.

         All Collections received by the Agent, and all other amounts received
by the Borrowers and delivered to the Agent, shall be credited to the Loan
Account; PROVIDED, that if an Event of Default has occurred and is continuing,
all Collections and other amounts received by Agent shall be distributed and
applied in the following order: FIRST, to the payment of any Fees, Expenses or
other Obligations due and payable to the Agent under any of the Credit
Documents, including Agent Advances and any other amounts advanced by the Agent
on behalf of the Lenders; SECOND, to the payment of any Fees, Expenses or other
Obligations due and payable to the Issuing Bank under any of the Credit
Documents; THIRD, to the ratable payment of any Fees, Expenses or other
Obligations due and payable to the Lenders under any of the Credit Documents
other than those Obligations specifically referred to in this Section; FOURTH,
to the ratable payment of interest due on the Revolving Loans; and, FIFTH, to
the ratable payment of principal due on the Revolving Loans.

         4.12     CALCULATIONS.

         All calculations of (i) interest hereunder and (ii) Fees, including,
without limitation, Unused Line Fees and Letter of Credit Fees, shall be made by
the Agent, on the basis of a year of 360 days, or, if such computation would
cause the interest and fees chargeable hereunder to exceed the Highest Lawful
Rate, 365/366 days, in each case for the actual number of days elapsed
(including the first day but excluding the last day) occurring in the period for
which such interest or Fees are payable. Each determination by the Agent of an
interest rate, Fee or other payment hereunder shall be conclusive and binding
for all purposes, absent demonstrable error.

         4.13     SPECIAL PROVISIONS RELATING TO LIBOR RATE LOANS.

                  (a) CONTINUATION. With respect to any Borrowing consisting of
         LIBOR Rate Loans, the Borrowers may, subject to the provisions of
         SECTION 4.13(c), elect to maintain such Borrowing or any portion
         thereof as consisting of LIBOR Rate Loans by selecting a new Interest
         Period for such Borrowing, which new Interest Period shall commence on
         the last day of 



                                      -36-

<PAGE>   43

          the immediately preceding Interest Period. Each selection of a new
          Interest Period shall be made by notice given not later than noon
          Chicago time on the third Business Day prior to the date of any such
          continuation relating to LIBOR Rate Loans, by the Funds Administrator
          to the Agent. Such notice by the Funds Administrator of a continuation
          (a "NOTICE OF CONTINUATION") shall be by telephone or facsimile
          transmission, and if by telephone, promptly confirmed in writing,
          substantially in the form of EXHIBIT C, in each case specifying (i)
          the date of such continuation, (ii) the aggregate amount of Revolving
          Loans subject to such continuation and (iii) the duration of the
          selected Interest Period. The Borrowers may elect to maintain more
          than one Borrowing consisting of LIBOR Rate Loans by combining such
          Borrowings into one Borrowing and selecting a new Interest Period
          pursuant to this SECTION 4.13(a). If the Borrowers shall fail to
          select a new Interest Period for any Borrowing consisting of LIBOR
          Rate Loans in accordance with this SECTION 4.13(a), such Revolving
          Loans will automatically, on the last day of the then existing
          Interest Period therefor, convert into Prime Rate Loans. The Agent
          shall give each Lender prompt notice by telephone or facsimile
          transmission of each Notice of Continuation.

                  (b) CONVERSION. The Borrowers may on any Business Day (so long
          as no Default or Event of Default has occurred and is continuing),
          upon notice (each such notice, a "NOTICE OF CONVERSION") given to the
          Agent, and subject to the provisions of SECTION 4.13(c), convert the
          entire amount of or a portion of all Revolving Loans of one Type
          comprising the same Borrowing into Revolving Loans of the other Type;
          PROVIDED, THAT any conversion of any LIBOR Rate Loans into Prime Rate
          Loans shall be made on, and only on, the last day of an Interest
          Period for such LIBOR Rate Loans and, upon conversion of any Prime
          Rate Loans into LIBOR Rate Loans, the Borrowers shall pay accrued
          interest to the date of conversion on the principal amount converted.
          Each such Notice of Conversion shall be given not later than Noon
          Chicago time on the Business Day prior to the date of any proposed
          conversion into Prime Rate Loans and on the third Business Day prior
          to the date of any proposed conversion into LIBOR Rate Loans. Subject
          to the restrictions specified above, each Notice of Conversion shall
          be by telephone or facsimile transmission, and if by telephone,
          promptly confirmed in writing, substantially in the form of EXHIBIT D,
          in each case specifying (i) the requested date of such conversion,
          (ii) the Type of Revolving Loans to be converted (iii) the portion of
          such Type of Revolving Loan to be converted, (iv) the Type of
          Revolving Loans such Revolving Loans are to be converted into and (v)
          if such conversion is into LIBOR Rate Loans, the duration of the
          Interest Period of such Revolving Loan. Each conversion shall



                                      -37-
<PAGE>   44

          be in an aggregate amount of not less than $1,000,000 or an integral
          multiple of $100,000 in excess thereof. The Borrowers may elect to
          convert the entire amount of or a portion of all Revolving Loans of
          one Type comprising more than one Borrowing into Revolving Loans of
          another Type by combining such Borrowings into one Borrowing;
          PROVIDED, THAT if the Borrowings so combined consist of LIBOR Rate
          Loans, such Loans shall have Interest Periods ending on the same date.

                  (c) CERTAIN LIMITATIONS ON LIBOR RATE LOANS. The right of the
          Borrowers to maintain, select, continue or convert LIBOR Rate Loans
          shall be limited as follows:

                             (i) If the Agent is advised by Bankers Trust
                  Company that it is not offering United States dollar deposits
                  (in the applicable amounts) in the London inter-bank market,
                  or the Agent determines that adequate and fair means do not
                  otherwise exist for ascertaining the LIBOR Rate or LIBOR Rate
                  Loans comprising any requested Borrowing, continuation or
                  conversion, the right of the Borrowers to select or maintain
                  LIBOR Rate Loans for such Borrowing or any subsequent
                  Borrowing shall be suspended until the Agent shall notify the
                  Funds Administrator and the Lenders that the circumstances
                  causing such suspension no longer exist, and each Revolving
                  Loan shall be made as a Prime Rate Loan.

                            (ii) If the Majority Lenders shall, at least two (2)
                  Business Days before the date of any requested Borrowing,
                  continuation or conversion, notify the Agent that the LIBOR
                  Rate for Revolving Loans comprising such Borrowing will not
                  adequately reflect the cost to such Lenders of making or
                  funding their respective Revolving Loans for such Borrowing,
                  the right of the Borrowers to select LIBOR Rate Loans for such
                  Borrowing shall be suspended until the Agent shall notify the
                  Funds Administrator and the Lenders that the circumstances
                  causing such suspension no longer exist, and each Revolving
                  Loan comprising such Borrowing and each other Borrowing
                  requested during such period of suspension shall be made as
                  a Prime Rate Loan.

                           (iii) If at any time any Lender determines (which
                  determination shall, absent demonstrable error, be conclusive
                  and binding on all parties) that the making, continuation or
                  conversion of any Revolving Loan as a LIBOR Rate Loan by such
                  Lender has become unlawful or impermissible by reason of
                  compliance by that Lender with any law, governmental rule,
                  regulation or order of any Governmental Authority (whether or
                  not having the force



                                      -38-

                  of law), then, and in any such event, such Lender may give
                  notice of that determination in writing, to the Agent and the
                  Funds Administrator and the Agent shall promptly transmit the
                  notice to each other Lender. Until such Lender gives notice
                  otherwise, the right of the Borrowers to select LIBOR Rate
                  Loans from that Lender shall be suspended and each Revolving
                  Loan made by that Lender, notwithstanding the Type of
                  Revolving Loan made by the other Lenders, shall be a Prime
                  Rate Loan and each LIBOR Rate Loan outstanding from that
                  Lender shall automatically, on the last day of the existing
                  Interest Period therefor (or earlier, if so required under
                  such law, rule, regulation or order), convert to a Prime Rate
                  Loan.

                            (iv) No Agent Advance shall be made as a LIBOR Rate
                  Loan.

                             (v) Subject to CLAUSE (vii) of this SECTION
                  4.13(c), no more than five (5) Interest Periods with respect
                  to LIBOR Rate Loans may be in effect at any time.

                            (vi) No Revolving Loans may be made, continued or
                  converted as or to LIBOR Rate Loans at any time that a Default
                  or Event of Default shall have occurred and be continuing.

                           (vii) Prior to the earliest to occur of (x) the
                  completion of the syndication by the Agent in the exercise of
                  its sole discretion, (y) ninety (90) days after the Closing
                  Date and (z) receipt by or for the account of MTLM of the net
                  proceeds of issuance of the Subordinated Notes, Borrowers may
                  only select LIBOR Loans having an Interest Period of one month
                  and only one such Interest Period may be in effect at any
                  time.

         (d)      COMPENSATION.

                             (i) Each Notice of Continuation and Notice of
                  Conversion shall be irrevocable by and binding on the
                  Borrowers. In the case of any Borrowing, continuation or
                  conversion that the related Notice of Borrowing, Notice of
                  Continuation or Notice of Conversion specifies is to be
                  comprised of LIBOR Rate Loans, the Borrowers shall indemnify
                  each Lender against any loss, cost or expense incurred by such
                  Person as a result of any failure to fulfill, on or before the
                  date for such Borrowing, continuation or conversion specified
                  in such Notice of Borrowing, Notice of Continuation or Notice
                  of Conversion, the applicable conditions set forth in ARTICLE
                  5, including, without limitation, any loss



                                      -39-
<PAGE>   46

                  (excluding loss of anticipated profits), cost or expense
                  incurred by reason of the liquidation or re-employment of
                  deposits or other funds acquired by such Lender to fund the
                  Revolving Loan to be made by such Lender as part of such
                  Borrowing, continuation or conversion.

                            (ii) If any payment of principal of, or conversion
                  or continuation of, any LIBOR Rate Loan is made other than on
                  the last day of the Interest Period for such Loan as a result
                  of a payment, prepayment, conversion or continuation of such
                  Loan or acceleration of the maturity of the Revolving Notes or
                  for any other reason, the Borrowers shall, upon demand by any
                  Lender (with a copy of such demand to the Agent), pay to the
                  Agent for the account of such Lender any amounts required to
                  compensate such Lender for any additional losses, costs or
                  expenses which it may reasonably incur as a result of such
                  payment, including, without limitation, any loss (excluding
                  loss of anticipated profits), cost or expense incurred by
                  reason of the liquidation or re-employment of deposits or
                  other funds acquired by any Lender to fund or maintain such
                  Loan.

                           (iii) Calculation of all amounts payable to a Lender
                  under this SECTION 4.13(d) shall be made as though such Lender
                  elected to fund all LIBOR Rate Loans by purchasing United
                  State dollar deposits in its LIBOR Lending Office's interbank
                  eurodollar market.

         4.14     INDEMNIFICATION IN CERTAIN EVENTS.

                  (a)      INCREASED COSTS.  If after the Closing Date, either
         (i) any change in or in the interpretation of any law or regulation is
         introduced, including, without limitation, with respect to reserve
         requirements applicable to the Agent, to any of the Lenders, Bankers
         Trust Company or any other affiliated banking or financial institution
         from whom any of the Lenders borrows funds or obtains credit (a
         "FUNDING BANK"), or (ii) the Agent, a Funding Bank or any of the
         Lenders complies with any future guideline or request from any central
         bank or other Governmental Authority proposed or promulgated after the
         date of the Agreement or (iii) the Agent, a Funding Bank or any of the
         Lenders reasonably determines that the adoption of any applicable law,
         rule or regulation regarding capital adequacy or any change therein, or
         any change in the interpretation or administration thereof by any
         Governmental Authority, central bank or comparable agency charged with
         the interpretation or administration thereof announced after the date
         of this Credit Agreement has or would have the effect described below,
         or the Agent, a Funding Bank or any of the Lenders complies with any
         request



                                      -40-
<PAGE>   47

         or directive regarding capital adequacy (whether or not having the
         force of law) of any such authority, central bank or comparable agency
         announced after the date of this Credit Agreement and in the case of
         any event set forth in this clause (iii), such adoption, change or
         compliance has or would have the effect of reducing the rate of return
         on any of such Person's capital as a consequence of its obligations
         hereunder to a level below that which such Person could have achieved
         but for such adoption, change or compliance (taking into consideration
         such Person's policies with respect to capital adequacy) by an amount
         reasonably deemed by such Person to be material, and any of the
         foregoing events described in CLAUSES (i), (ii) OR (iii) increases the
         cost to the Agent, or any of the Lenders of (a) funding or maintaining
         any Commitment or (b) issuing, causing the issuance of making or
         maintaining any Letter of Credit or of purchasing or maintaining any
         participation therein, or reduces the amount receivable in respect
         thereof by the Agent or any Lender, then the Borrowers shall upon
         demand by the Agent at any time within one hundred eighty (180) days
         after the date on which an officer of the Agent, such Funding Bank or
         such Lender, as the case may be, responsible for overseeing this Credit
         Agreement knows or has reason to know of its right to additional
         compensation under this SECTION 4.14(a), pay to the Agent, for the
         account of such Lender or, as applicable, the Agent or a Funding Bank,
         additional amounts sufficient to reimburse the Agent, such Funding Bank
         and such Lender against such increase in cost or reduction in amount
         receivable; PROVIDED, HOWEVER, that if the Agent or any such Lender or
         Funding Bank, as the case may be, fails to deliver such demand within
         such 180 day period, such entity shall only be entitled to additional
         compensation for any such costs incurred from and after the date that
         is one hundred eighty (180) days prior to the date the Borrowers
         received such demand; and PROVIDED FURTHER, HOWEVER, that before making
         any such demand, the Agent and each Lender agree to use reasonable
         efforts (consistent with such Person's internal policy and legal and
         regulatory restrictions) to mitigate or avoid such increased costs,
         including, without limitation, designating a different Applicable
         Lending Office if the making of such a designation would avoid the need
         for, or reduce the amount of, such increased cost and so long as such
         efforts would not, in the reasonable judgment of such Person, be
         otherwise disadvantageous to such Person. A certificate as to the
         amount of such increased cost, and setting forth in reasonable detail
         the calculation thereof, shall be submitted to the Funds Administrator
         by the Agent, or the applicable Lender or Funding Bank, and shall be
         conclusive absent demonstrable error.

                  (b) Each Lender will promptly notify the Agent, and the Agent
         will promptly notify the Funds Administrator, of any 



                                      -41-

<PAGE>   48

         event of which it has knowledge that would entitle such entity to
         additional compensation under this SECTION 4.14. Neither the Agent nor
         any Lender shall request any additional compensation under this SECTION
         4.14 unless it is generally making similar requests of other borrowers
         similarly situated, and the Agent and each Lender agrees to use a
         reasonable basis for calculating amounts allocable to its commitment to
         lend or its Loans and Letter of Credit Obligations, if any, hereunder.

         4.15     SUBSTITUTION OF LENDERS.

         In the event the Borrowers become obligated to pay additional amounts
to any Lender pursuant to SECTION 4.14, or any Lender gives notice under SECTION
4.13(c)(iii), or any Lender is a Defaulting Lender, the Funds Administrator may
designate another Lender (with such other Lender's consent) reasonably
acceptable to the Agent (such other Lender herein called a "REPLACEMENT LENDER")
to purchase the Loans and other Obligations of such Lender and such Lender's
rights hereunder, without recourse to or warranty by, or expense to, such Lender
for a purchase price equal to the outstanding principal amount of the Loans
owing to such Lender PLUS any accrued but unpaid interest on such Loans and
other Obligations and accrued but unpaid Unused Line Fees in respect of such
Lender's Commitment and any other amounts payable to such Lender under this
Credit Agreement, and to assume all the obligations of such Lender hereunder
and, upon such purchase, such Lender shall on longer be a party hereto or have
any rights hereunder (other than indemnities and other similar rights applicable
to such Lender prior to the date of such assignment and assumption) and shall be
relieved from all obligations to the Borrowers hereunder, and the Replacement
Lender shall succeed to the rights and obligations of such Lender hereunder.


                        ARTICLE 5. CONDITIONS PRECEDENT.

         5.1      CONDITIONS PRECEDENT TO INITIAL REVOLVING LOAN AND LETTER
                  OF CREDIT.

         The obligation of each Lender to fund its Proportionate Share of the
initial Borrowing (or, if it shall occur earlier, the obligation of the Agent to
cause the issuance by the Issuing Bank of the initial Letter of Credit and of
each Lender to purchase a participation therein) is in each case subject to the
satisfaction or waiver of the following conditions precedent:

                  (a) CLOSING DOCUMENTS. The Agent and the Lenders shall have
         received each of the agreements, opinions, reports, approvals,
         consents, certificates and other documents set forth on the List of
         Closing Documents attached hereto as SCHEDULE A (the "CLOSING DOCUMENT
         LIST").

<PAGE>   49

                  (b) FEES AND EXPENSES. All Fees and Expenses payable by the
         Borrowers hereunder on or before the Closing Date shall have been paid
         in full.

                  (c) OTHER DOCUMENTS. Borrowers shall have delivered or caused
         to be delivered to the Agent, in each case in form and substance
         satisfactory to Agent, (i) all information required pursuant to SECTION
         7.2 and (ii) such other business and/or financial and data and other
         information as the Agent shall reasonably request.

                  (d) OFFICER'S CERTIFICATE. The Agent shall have received a
         certificate dated the Closing Date signed on behalf of the Funds
         Administrator and each of the Borrowers by a Responsible Officer of the
         Funds Administrator stating that all of the conditions set forth in
         SECTIONS 5.2(a) and (b) have been satisfied on and as of such date.

         5.2      CONDITIONS PRECEDENT TO ALL REVOLVING LOANS AND LETTERS
                  OF CREDIT.

         The obligation of each Lender to fund its Proportionate Share of any
requested Revolving Loan (or of the Agent to cause the Issuing Bank to issue any
requested Letter of Credit and of each Lender to purchase a participation
therein) is in each case subject to the satisfaction of the conditions precedent
set forth below. Each Notice of Borrowing, each Letter of Credit Request and
each issuance by any Borrower of a check drawn against, or request for transfer
from, the Disbursement Account shall constitute a representation and warranty to
the Agent and each Lender by the Borrowers that such conditions are satisfied.

                  (a) All representations and warranties contained in this
         Credit Agreement and the other Credit Documents are true and correct in
         all material respects on and as of the date of such Notice of
         Borrowing, Letter of Credit Request, or issuance of a check drawn
         against, or request for transfer from, the Disbursement Account both
         before and after giving effect thereto and to the application of the
         proceeds thereof, in each case as if then made, other than
         representations and warranties that expressly relate solely to an
         earlier date (in which case such representations and warranties shall
         have been true and accurate in all material respects on and as of such
         earlier date); and

                  (b) No Default or Event of Default shall have occurred or
         could reasonably be expected to result from the making of the requested
         Revolving Loan or the issuance of the requested Letter of Credit, which
         has not been cured or waived.

Agent and the Lenders that the representations and warranties contained in this

may be, duly organized, validly existing and in good standing under the laws of
the respective states or other jurisdictions of their formation, (ii) have the
power and authority to own their respective properties and assets and to
transact their respective businesses in which they presently are, or propose to
be, engaged and (iii) are duly qualified and are authorized to do business and
are in good standing in each of the respective jurisdictions where they
presently are, or propose to be, engaged in business, in each case, except where
any failures to do so could not reasonably be expected singly or in the
aggregate to have a Material Adverse Effect. SCHEDULE B, PART 6.1 lists all
jurisdictions in which each Credit Party and each Subsidiary of each Credit
Party are qualified to do business as foreign corporations, limited partnerships
or limited liability companies, as the case may be.

         6.2      AUTHORITY.

         Each Credit Party and each Subsidiary of each Credit Party has the
requisite power and authority to execute, deliver and perform the respective
Credit Documents to which they are parties. All corporate, partnership or
similar action necessary for the execution, delivery and performance of any of
the Credit Documents by each Credit Party and each Subsidiary of each Credit
Party which is a party thereto has been taken.

         6.3      ENFORCEABILITY.

         This Credit Agreement and each of the other Credit Documents are the
legal, valid and binding obligations of each Credit Party and each Subsidiary of

         6.4      NO CONFLICT.

         The execution, delivery and performance of each Credit Document by each
Credit Party and each Subsidiary of each Credit Party which are parties thereto
are not in contravention of (i) the Governing Documents of such Persons, or (ii)
any Requirement of Law, or (iii) any indenture, contract, agreement or
instrument or other commitment to which any or all of such Persons are parties
or by which any of such Persons or any of its properties are bound, and will
not, except as contemplated herein, result in the imposition of any Liens upon
any of the properties of any of such Persons.

         6.5      CONSENTS AND FILINGS.

         No consent, authorization, permit or filing is required in connection
with the execution, delivery and performance of this Credit Agreement or any
other Credit Document by any Credit Party or any Subsidiary of any Credit Party
which are parties thereto, or in connection with the continuing operations of
such Persons, except (i) those that have been obtained or made and (ii) filings
necessary to create, perfect or retain the perfection of Liens against the 
Collateral.

         6.6      GOVERNMENT REGULATION.

         No Borrower nor any Subsidiary of any Borrower is subject to regulation

         The present fair saleable value of the assets of each Borrower exceeds
all its probable liability on its existing debts as they become absolute and
matured, including those to be incurred pursuant to this Credit Agreement and
the other Credit Documents. No Borrower (i) has unreasonably small capital in
relation to the business in which it is or proposes to be engaged and (ii) has
incurred and believes that it will incur, after giving effect to the
transactions contemplated by this Credit Agreement, debts beyond its ability to
pay as such debts become due.

         6.8      RIGHTS IN COLLATERAL; PRIORITY OF LIENS.

         All property constituting Collateral is owned or leased by the
respective Borrowers, free and clear of any and all Liens in favor of third

<PAGE>   52

filing of the UCC financing and termination statements, in each case listed in
the Closing Document List, the security interests granted pursuant to the Credit
Documents constitute valid and enforceable first, prior (subject to Permitted
Liens) and perfected Liens on the Collateral, to the extent such Liens can be
perfected by the filing of such financing statements.

         6.9      FINANCIAL DATA.

                  (a) The Borrowers have provided or caused to be provided to

         following Financial Statements: (i) audited Financial Statements as of

         necessity of any request of the Majority Lenders or notice or other
         demand to the Funds Administrator or any of the Borrowers) the
         Commitments shall be immediately terminated and, at all times
         thereafter, all Revolving Loans made by any Lender pursuant to this
         Credit Agreement shall be at such Lender's sole discretion, unless such
         Event of Default is waived in accordance with SECTION 11.11, in which

         thereunder. Such deposit shall be held by the Agent and used to

         9.3      RESCISSION OF ACCELERATION.

         After acceleration of the maturity of all or any part of the
Obligations, if the Borrowers pay all accrued interest and all principal due
(other than by reason of the acceleration) and all Events of Default are waived
in accordance with SECTION 11.11, the Majority Lenders may elect in their sole
discretion, to rescind the acceleration and return to the Borrowers any cash
collateral, if any, deposited with the Agent pursuant to SECTION 9.2(c). (This
Section is intended only to bind all of the Lenders to a decision of the
Majority Lenders and not to confer any right on the Borrowers, even if the
described conditions for the Majority Lenders' election may be met.)

         9.4      REMEDIES.

         Upon the occurrence and during the continuance of an Event of Default,
upon the written request and at the direction of the Majority Lenders, the Agent
may exercise any rights and remedies available to it under applicable law
(including under the Code) and under the Collateral Documents. The foregoing
rights and remedies are not intended to be exhaustive and the full or partial
exercise of any right or remedy shall not preclude the full or partial exercise
of any other right or remedy available under this Credit Agreement, any other
Credit Document, at equity or at law.

         9.5      RIGHT OF SETOFF.

         In addition to and not in limitation of all rights of offset that any
Lender may have under applicable law, upon the occurrence and during the
continuance of any Event of Default, and whether or not any Lender has made any
demand or the Obligations of any Credit Party have matured, each Lender shall
have the right to appropriate and apply to the payment of the Obligations of
such Credit Party all deposits and other obligations then or thereafter owing by
such Lender to such Credit Party. Each Lender exercising such rights shall
notify the Agent thereof and any amount received as a result of the exercise of
such rights shall be shared by the Lenders in accordance with SECTION 2.5.

         9.6      LICENSE OF USE OF SOFTWARE AND OTHER INTELLECTUAL
                  PROPERTY.

         Unless expressly prohibited by the licensor thereof, if any, the Agent
is hereby granted a license to use all computer software programs, data bases,
processes and materials used by the Borrowers in connection with their
respective businesses or in connection with any Collateral. The Agent agrees not
to use any such license other than after the occurrence and during the
continuance of an Event of Default.

         9.7      APPLICATION OF PROCEEDS; SURPLUS; DEFICIENCIES.

         The net cash proceeds resulting from the Agent's exercise of any of the
foregoing rights against any Collateral (after deducting all of the Agent's
Expenses related thereto) shall be applied by the Agent to the payment of the
Obligations, whether due or to become due, in the order set forth in SECTION
4.11. The Borrowers shall remain liable to the Agent and the Lenders for any
deficiencies, and the Agent and the Lenders in turn agree to remit to the
Borrowers or its successors or assigns, any surplus resulting therefrom.


                             ARTICLE 10. THE AGENT.

         10.1     APPOINTMENT OF AGENT.

                  (a)      Each Lender hereby designates BTCC as Agent to act
         as herein specified.  Each Lender hereby irrevocably authorizes, and
         each holder of any Revolving Note, by the acceptance of such Note,
         shall be deemed irrevocably to authorize the Agent to take such action
         on its behalf under the provisions of this Credit Agreement and the
         other Credit Documents and any other instruments and agreements
         referred to herein and therein and to exercise such powers and to
         perform such duties hereunder and thereunder as are specifically
         delegated to or required of the Agent by the terms hereof and thereof
         and such other powers as are reasonably incidental thereto. The Agent
         shall hold all Collateral and all payments of principal, interest, Fees
         (other than Fees that are exclusively for the account of the Agent),
         charges and Expenses received pursuant to this Credit Agreement or any
         other Credit Document for the ratable benefit of the Lenders. The Agent
         may perform any of its duties hereunder by or through its agents or
         employees.

                  (b) Other than rights of the Credit Parties under SECTION
         10.9, the provisions of this ARTICLE 10 are for the benefit of the
         Agent and the Lenders only and none of the Credit Parties or any other
         Persons shall have any rights as a third party beneficiary of any of
         the provisions hereof. In performing its functions and duties under
         this Credit Agreement and the other Credit Documents, the Agent shall
         act only for the Lenders and does not assume and shall not be deemed to
         have assumed any obligation toward or relationship of agency or trust
         with or for any Credit Party.

<PAGE>   81

         10.2     NATURE OF DUTIES OF AGENT.

         The Agent has no duties or responsibilities except those expressly set
forth in the Credit Documents. Neither the Agent nor any of its officers,
directors, employees or agents shall be liable for any action taken or omitted
hereunder or in connection herewith, unless caused by its or their gross
negligence or willful misconduct. The duties of the Agent shall be mechanical
and administrative in nature; the Agent shall not have by reason of this Credit
Agreement or any of the other Credit Documents a fiduciary relationship in
respect of any Lender or any participant of any Lender; and nothing in this
Credit Agreement or any other Credit Document, expressed or implied, is intended
to or shall be so construed as to impose upon the Agent any obligations in
respect of this Credit Agreement or any other Credit Document, except as
expressly set forth herein or therein.

         10.3     LACK OF RELIANCE ON AGENT.

                  (a) Independently and without reliance upon the Agent, each
         Lender, to the extent it deems appropriate, has made and shall continue
         to make (i) its own independent investigation of the financial or other
         condition and affairs of each Credit Party in connection with the
         taking or not taking of any action in connection herewith and (ii) its
         own appraisal of the creditworthiness of each Credit Party, and, except
         as expressly provided in this Credit Agreement, the Agent shall have no
         duty or responsibility, either initially or on a continuing basis, to
         provide any Lender with any credit or other information with respect
         thereto, whether coming into its possession before the making of the
         Revolving Loans or at any time or times thereafter.

                  (b) The Agent shall not be responsible to any Lender for any
         recitals, statements, information, representations or warranties herein
         or in any document, certificate or other writing delivered in
         connection herewith or for the execution, effectiveness, genuineness,
         validity, enforceability, collectibility, priority or sufficiency of
         this Credit Agreement or any of the other Credit Documents or the
         financial or other condition of any Credit Party. The Agent shall not
         be required to make any inquiry concerning either the performance or
         observance of any other terms, provisions or conditions of this Credit
         Agreement or any of the other Credit Documents, or the financial
         condition of any Credit Party, or the existence or possible existence
         of any Default or Event of Default, unless specifically requested to do
         so in writing by any Lender.

         10.4     CERTAIN RIGHTS OF THE AGENT.

         The Agent shall have the right to request instructions from the Lenders
by notice to each of such Lenders. If the Agent shall 



                                      -75-

<PAGE>   82

request instructions from the Lenders with respect to any act or action
(including the failure to act) in connection with this Credit Agreement, the
Agent shall be entitled to refrain from such act or taking such action unless
and until the Agent shall have received instructions from such Lenders, and the
Agent shall not incur liability to any Person by reason of so refraining.
Without limiting the foregoing, no Lender shall have any right of action
whatsoever against the Agent as a result of the Agent acting or refraining from
acting hereunder in accordance with the instructions of the requisite Lenders
required to give such instructions hereunder. The Agent may give any notice
required under ARTICLE 9 hereof without the consent of any of the Lenders unless
otherwise directed by the Majority Lenders in writing and will, at the direction
of the Majority Lenders, give any such notice required under ARTICLE 9.

         10.5     RELIANCE BY AGENT.

         The Agent shall be entitled to rely, and shall be fully protected in
relying, upon any note, writing, resolution, notice, statement, certificate,
telex, teletype or telecopier message, cablegram, radiogram, order or other
documentary, facsimile or telephone message believed by it to be genuine and
correct and to have been signed, sent or made by the proper person. The Agent
may consult with legal counsel (including counsel for the Credit Parties with
respect to matters concerning the Credit Parties), independent public
accountants and other experts selected by it and shall not be liable for any
action taken or omitted to be taken by it in good faith in accordance with the
advice of such counsel, accountants or experts.

         10.6     INDEMNIFICATION OF AGENT.

         To the extent the Agent is not reimbursed and indemnified by the
Borrowers, each Lender will reimburse and indemnify the Agent, in proportion to
its respective Commitment, for and against all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses (including
counsel fees and disbursements) or disbursements of any kind or nature
whatsoever which may be imposed on, incurred by or asserted against the Agent in
performing its duties hereunder, in any way relating to or arising out of this
Credit Agreement; PROVIDED, THAT no Lender shall be liable for any portion of
such liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements resulting from the Agent's gross
negligence or willful misconduct.

         10.7     THE AGENT IN ITS INDIVIDUAL CAPACITY.

         With respect to its obligation to lend under this Credit Agreement, the
Revolving Loans made by it and the Revolving Notes 



                                      -76-

<PAGE>   83

issued to it and its participation in Letters of Credit issued hereunder, the
Agent shall have the same rights and powers hereunder as any other Lender or
holder of a Revolving Note or participation interests and may exercise the same
as though it was not performing the duties specified herein; and the terms
"Lenders," "Lenders," "Majority Lenders," "holders of Revolving Notes," or any
similar terms shall, unless the context clearly otherwise indicates, include the
Agent in its individual capacity. The Agent may accept deposits from, lend money
to, acquire equity interests in, and generally engage in any kind of banking,
trust, financial advisory or other business with any Credit Party or any
Affiliate of any Credit Party as if it were not performing the duties specified
herein, and may accept fees and other consideration from any Credit Party for
services in connection with this Credit Agreement and otherwise without having
to account for the same to the Lenders.

         10.8     HOLDERS OF NOTES.

         The Agent may deem and treat the payee of any Revolving Note as the
owner thereof for all purposes hereof unless and until a written notice of the
assignment or transfer thereof shall have been filed with the Agent. Any
request, authority or consent of any Person who, at the time of making such
request or giving such authority or consent, is the holder of any Revolving
Note, shall be conclusive and binding on any subsequent holder, transferee or
assignee of such Revolving Note or of any Revolving Note or Revolving Notes
issued in exchange therefor.

         10.9     SUCCESSOR AGENT.

                  (a) The Agent may, upon five (5) Business Days' notice to the
         Lenders and the Funds Administrator, resign at any time (effective upon
         the appointment of a successor Agent pursuant to the provisions of this
         SECTION 10.9) by giving written notice thereof to the Lenders and the
         Funds Administrator. Upon any such resignation, the Majority Lenders
         shall have the right, upon five (5) days' notice and approval by the
         Credit Parties (which approval shall not be unreasonably withheld or
         delayed) to appoint a successor Agent. If no successor Agent shall have
         been so appointed by the Majority Lenders and accepted such
         appointment, within thirty (30) days after the retiring Agent's giving
         of notice of resignation, then the retiring Agent may, on behalf of the
         Lenders (and with the approval of the Funds Administrator, which
         approval shall not be unreasonably withheld or delayed), appoint a
         successor Agent, which shall be a bank or a trust company or other
         financial institution which maintains an office in the United States,
         or a commercial bank organized under the laws of the United States of
         America or of any State thereof, or any Affiliate of such bank or trust
         company or other financial institution which is engaged in the banking
         business, having a combined capital and surplus of at least
         $500,000,000.

<PAGE>   84

                  (b) Upon the acceptance of any appointment as Agent hereunder
         by a successor Agent, such successor Agent shall thereupon succeed to
         and become vested with all the rights, powers, privileges and duties of
         the retiring Agent, and the retiring Agent shall be discharged from its
         duties and obligations under this Credit Agreement and the other Credit
         Documents. After any retiring Agent's resignation hereunder as Agent,
         the provisions of this ARTICLE 10 shall inure to its benefit as to any
         actions taken or omitted to be taken by it while it was Agent under or
         in connection with this Credit Agreement.

        10.10     COLLATERAL MATTERS.

                  (a) Each Lender authorizes and directs the Agent to enter into
         the Collateral Documents for the benefit of the Lenders. Each Lender
         hereby agrees, and each holder of any Revolving Note by the acceptance
         thereof will be deemed to agree, that, except as otherwise set forth
         herein or in the other Credit Documents, any action taken by the
         Majority Lenders in accordance with the provisions of this Credit
         Agreement and the other Credit Documents, and the exercise by the
         Majority Lenders of the powers set forth herein or therein, together
         with such other powers as are reasonably incidental thereto, shall be
         authorized and binding upon all of the Lenders. The Agent is hereby
         authorized on behalf of all of the Lenders, without the necessity of
         any notice to or further consent from any Lender, from time to time so
         long as an Event of Default shall not then exist, to take any action
         with respect to any Collateral or Collateral Documents which may be
         necessary to perfect and maintain the perfection of the Liens upon the
         Collateral granted pursuant to the Collateral Documents.

                  (b)      The Lenders hereby authorize the Agent, at its
         option and in its discretion, to release any Lien granted to or held by
         the Agent upon any Collateral (i) upon termination of the Commitments
         and payment and satisfaction of all of the Obligations at any time
         arising under or in respect of this Credit Agreement or the other
         Credit Documents or the transactions contemplated hereby or thereby, 
         (ii) if approved, authorized or ratified in writing by the Majority
         Lenders, unless such release is required to be approved by all of the
         Lenders pursuant to SECTION 11.11; or (iii) constituting property sold
         or to be sold or disposed of as part of or in connection with any
         disposition thereof permitted hereunder. Upon request by the Agent at
         any time, the Lenders will confirm in writing the Agent's authority to
         release particular types or items of Collateral pursuant to this
         SECTION 10.10.

<PAGE>   85

                  (c) The Agent shall have no obligation whatsoever to the
         Lenders or to any other Person to assure that the Collateral exists or
         is owned by any Borrower or is cared for, protected or insured or that
         the Liens granted to the Agent in or pursuant to any of the Collateral
         Documents have been properly or sufficiently or lawfully created,
         perfected, protected or enforced or are entitled to any particular
         priority, or to exercise or to continue exercising at all or in any
         manner or under any duty of care, disclosure or fidelity any of the
         rights, authorities and powers granted or available to the Agent in
         this SECTION 10.10 or in any of the Collateral Documents, it being
         understood and agreed that in respect of the Collateral, or any act,
         omission or event related thereto, the Agent may act in any manner it
         may deem appropriate, in its sole discretion, given the Agent's own
         interest in the Collateral as one of the Lenders and that the Agent
         shall have no duty or liability whatsoever to the Lenders, except for
         its gross negligence or willful misconduct. The Agent agrees to conduct
         or cause to be conducted at least one audit of the Collateral during
         each year that this Credit Agreement shall remain in effect.

        10.11     ACTIONS WITH RESPECT TO DEFAULTS.

        In addition to the Agent's right to take actions on its own accord as
permitted under this Credit Agreement, the Agent shall take such action with
respect to a Default or Event of Default as shall be directed by the Majority
Lenders; PROVIDED, THAT until the Agent shall have received such directions, the
Agent may (but shall not be obligated to) take such action, or refrain from
taking such action, with respect to such Default or Event of Default as it shall
deem advisable and in the best interests of the Lenders.

        10.12     DELIVERY OF INFORMATION.

        The Agent shall not be required to deliver to any Lender originals or
copies of any documents, instruments, notices, communications or other
information received by the Agent from any of the Credit Parties or any
Subsidiary of any of the Credit Parties, the Majority Lenders, any Lender or any
other Person under or in connection with this Credit Agreement or any other
Credit Document except (i) as specifically provided in this Credit Agreement or
any other Credit Document and (ii) as specifically requested from time to time
in writing by any Lender with respect to a specific document, instrument, notice
or other written communication received by and in the possession of the Agent at
the time of receipt of such request and then only in accordance with such
specific request.

         consent of the Agent and, in the case of any such assignment to a bank
         or financial institution not disclosed to the Funds Administrator on or
         prior to the Closing Date, the consent of the Funds Administrator
         (which consent, in the case of the Funds Administrator, shall not be
         unreasonably withheld or delayed), and upon execution and delivery to
         the Agent, for its acceptance and recording in the Register, of an
         agreement in substantially the form of EXHIBIT G (an "ASSIGNMENT AND
         ASSUMPTION AGREEMENT"), together with surrender of any Revolving Note
         or Revolving Notes subject to such assignment and a processing and
         recordation fee of $2,500, such assignment shall be effective and ANNEX
         I hereto shall be deemed to be modified accordingly. No such assignment
         shall be for less than $10,000,000 of the Commitments unless it is to
         another Lender or is an assignment of all of such Lender's rights and
         obligations under this Credit Agreement. (This Section does not apply
         to branches and Affiliates of a Lender, it being understood that a
         Lender may make, carry or transfer Revolving Loans at or for the
         account of any of its branch offices or Affiliates without consent of
         the Borrowers, the Agent or any other Lender.)

                  (c) AGENT'S REGISTER. The Agent shall maintain a register of
         the names and addresses of the Lenders, their Commitments, and the
         principal amount of their Revolving Loans (the "REGISTER") at the
         address specified for the Agent in SECTION 11.7. The Agent shall also
         maintain a copy of each Assignment and Assumption Agreement delivered
         to and accepted by it, and modify the Register to give effect to each
         Assignment and Assumption Agreement. Upon its receipt of each




                                      -82-

<PAGE>   89
         Assignment and Assumption Agreement and surrender of the affected
         Revolving Note or Revolving Notes, the Agent will give prompt notice
         thereof to the Funds Administrator and deliver to the Funds
         Administrator a copy of the Assignment and Assumption Agreement and the
         surrendered Revolving Note or Revolving Notes. Within five Business
         Days after its receipt of such notice, the Borrowers shall execute and
         deliver to the Agent a substitute Revolving Note or Revolving Notes to
         the order of the assignee in the amount of the Commitment or
         Commitments assumed by it and to the assignor in the amount of the
         Commitment or Commitments retained by it, if any. Such substitute
         Revolving Note or Revolving Notes shall re-evidence the Indebtedness
         outstanding under the surrendered Revolving Note or Revolving Notes and
         shall be dated as of the Closing Date. The Agent shall be entitled to
         rely upon the Register exclusively for purposes of identifying the
         Lenders hereunder. The Register shall be available for inspection by
         the Credit Parties and the Lenders (or any of them) at any reasonable
         time and from time to time upon reasonable notice to the Agent.

                  (d) PARTICIPATIONS. Each Lender may sell participations
         (without the consent of the Agent, any Credit Party or any other
         Lender) to one or more parties in or to all or a portion of its rights
         and obligations under this Credit Agreement, the Revolving Notes and
         the other Credit Documents. Notwithstanding a Lender's sale of a
         participation interest, its obligations hereunder shall remain
         unchanged. The Credit Parties, the Agent, and the other Lenders shall
         continue to deal solely and directly with such Lender. No participant
         shall have rights to approve any amendment or waiver of this Credit
         Agreement or any of the other Credit Documents except to the extent
         such amendment or waiver would (i) increase the participant's
         obligation in respect of the Commitment of the Lender from whom the
         participant purchased its participation interest; (ii) reduce the
         principal of, or stated rate or amount of interest on, the Revolving
         Loans subject to such participation, (iii) postpone any maturity date
         fixed for final payment of principal of the Revolving Loans subject to
         the participation interest and (iv) release any guarantor of the
         Obligations or all or a substantial portion of the Collateral, other
         than when otherwise permitted hereunder.

         11.9     CONFIDENTIALITY.

                  (a) Each Lender agrees that it will use its best efforts not
         disclose to any Person, without the prior consent of the Funds
         Administrator, any information with respect to any of the Credit
         Parties or any Subsidiary of any of the Credit Parties which is
         furnished pursuant to this Credit Agreement and which is designated by
         the respective Credit Parties to 




                                      -83-

<PAGE>   90

         the Lenders in writing as confidential (the "CREDIT PARTY
         INFORMATION"), PROVIDED, THAT, each Lender may disclose any such
         information (i) to its employees, auditors, or counsel, or to another
         Lender if the disclosing Lender or such disclosing Lender's holding or
         parent company in its sole discretion determines that any such party
         should have access to such information, (ii) as has become generally
         available to the public, (iii) as may be required in any report,
         statement or testimony submitted to any Governmental Authority having
         or claiming to have jurisdiction over such Lender, (iv) as may be
         required in response to any summons or subpoena or in connection with
         any litigation, (v) in order to comply with any Requirement of Law, and
         (vi) to any actual or prospective transferee or participant in
         connection with any contemplated transfer or participation of any of
         the Revolving Notes or Commitments or any interest therein by such
         Lender, so long as prior to such disclosure such prospective or actual
         transferee or participant has agreed to preserve the confidentiality of
         such information on terms substantially similar to those set forth in
         this SECTION 11.9 or on terms otherwise satisfactory to the Funds
         Administrator.

                  (b) In the event that the Agent or any Lender is requested or
         becomes legally compelled (by interrogatories, requests for information
         or documents, subpoena, civil investigative demand or similar process)
         to disclose any of the Credit Party Information, such Person will (i)
         provide the Funds Administrator with prompt written notice so that the
         Credit Parties may seek a protective order or other appropriate remedy
         and/or waive compliance with the provisions of this SECTION 11.9; (ii)
         unless the Credit Parties waive compliance by such Person with the
         provisions of this SECTION 11.9, make a timely objection to the request
         or compulsion to provide such Credit Party Information on the basis
         that such Credit Party Information is confidential and subject to the
         agreements contained in this SECTION 11.9; and (iii) take action as is
         necessary to preserve such confidentiality, such as seeking a
         protective order or other appropriate remedy.

         In the event that a protective order or other remedy is not obtained,
or the Credit Parties waive compliance with the provisions of this SECTION 11.9,
such Person will furnish only that portion of the Credit Party Information which
is legally required to be furnished and will exercise such Person's best efforts
to obtain reliable assurance that confidential treatment will be accorded to the
Credit Party Information.

        11.10     INDEMNIFICATION.

        The Borrowers hereby jointly and severally indemnify and agree to defend
and hold harmless the Agent and each of the Lenders and their respective
directors, officers, agents, employees and counsel from and against any and all
losses, claims, damages, liabilities, deficiencies, judgments or expenses
incurred by any of them (except to the extent that it is finally judicially
determined to have resulted from their own gross negligence or willful
misconduct) arising out of or by reason of (a) any litigations, investigations,
claims or proceedings which arise out of (i) this Credit Agreement or the
transactions contemplated hereby, (ii) the issuance of the Letters of Credit,
(iii) the failure of the Issuing Bank to honor a drawing under any Letter of
Credit, as a result of any act or omission, whether rightful or wrongful, of any
present or future de jure or de facto government or Governmental Authority, (iv)
any actual or proposed use by any Borrower of the proceeds of the Revolving
Loans or (v) the Agent's or the Lenders' entering into this Credit Agreement,
the other Credit Documents or any other agreements and documents relating
hereto, including, without limitation, amounts paid in settlement, court costs
and the fees and disbursements of counsel incurred in connection with any such
litigation, investigation, claim or proceeding or any advice rendered in
connection with any of the foregoing and (b) any remedial or other action taken
by any of the Borrowers or any of the Lenders in connection with compliance by
any of the Borrowers or any Subsidiary of any of the Borrowers, or any of their
respective properties, with any federal, state or local environmental laws,
acts, rules, regulations, orders, directions, ordinances, criteria or
guidelines.

        11.11     AMENDMENTS AND WAIVERS.

        No amendment or waiver of any provision of this Credit Agreement, any
part of SCHEDULE B, or any other Credit Document shall be effective unless in
writing and signed by the Majority Lenders (or by the Agent on their behalf),
except that:

                  (a) the consent of all the Lenders is required to (i) increase
        the Commitments, (ii) reduce the principal of, or interest on, any
        Revolving Note, any Letter of Credit reimbursement obligations or any
        Fees hereunder (other than Fees that are exclusively for the account of
        the Agent), (iii) postpone any date fixed for any payment in respect of
        principal of, or interest on, any Revolving Note, any Letter of Credit
        reimbursement obligations or any Fees hereunder, (iv) change the
        percentage of the Commitments, or any minimum requirement necessary for
        the Lenders or the Majority Lenders to take any action hereunder, (v)
        amend or waive this SECTION 11.11(a), or change the definition of
        Majority Lenders or (vi) except as otherwise expressly provided in this
        Credit Agreement, and other than in connection with the financing,
        refinancing, sale or other disposition of any asset of a Borrower
        permitted under this Credit Agreement, release any Liens in favor of the
        Agent on any of the Collateral; and




                                      -85-

<PAGE>   92

                  (b) the consent of the Agent shall be required for any
        amendment, waiver or consent affecting the rights or duties of the Agent
        under any Credit Document, in addition to the consent of the Lenders
        otherwise required by this Section.

        Neither the consent of the Funds Administrator nor any other Credit
Party shall be required for any amendment, modification or waiver of the
provisions of ARTICLE 10 (other than SECTION 10.9). The Funds Administrator, the
other Credit Parties and the Lenders each hereby authorize the Agent to modify
this Credit Agreement by unilaterally amending or supplementing ANNEX I to
reflect assignments of the Commitments. Notwithstanding the foregoing, the
Credit Parties may amend SCHEDULE B, PARTS 6.1, 6.10, 6.14 and 6.16, without the
consent of the Majority Lenders.

        11.12     COUNTERPARTS AND EFFECTIVENESS.

        This Credit Agreement and any waiver or amendment hereto may be executed
in any number of counterparts and by the different parties hereto in separate
counterparts, each of which when so executed and delivered shall be an original,
but all of which shall together constitute one and the same instrument. This
Credit Agreement shall become effective on the date on which all of the parties
hereto shall have signed a copy hereof (whether the same or different copies)
and shall have delivered the same to the Agent.

        11.13     SEVERABILITY.

        In case any provision in or obligation under this Credit Agreement, the
Revolving Notes or any of the other Credit Documents shall be invalid, illegal
or unenforceable in any jurisdiction, the validity, legality and enforceability
of the remaining provisions or obligations, or of such provision or obligation
in any other jurisdiction, shall not in any way be affected or impaired thereby.

        11.14     MAXIMUM RATE.

        Notwithstanding anything to the contrary contained elsewhere in this
Credit Agreement or in any other Credit Document, the Borrowers, the Agent, and
the Lenders hereby agree that all agreements among them under this Credit
Agreement and the other Credit Documents, whether now existing or hereafter
arising and whether written or oral, are expressly limited so that in no
contingency or event whatsoever shall the amount paid, or agreed to be paid, to
the Agent or any Lender for the use, forbearance, or detention of the money
loaned to the Borrowers and evidenced hereby or thereby or for the performance
or payment of any covenant or obligation contained herein or therein, exceed the
Highest Lawful Rate. If due to any circumstance whatsoever, fulfillment of any
provisions of this Credit Agreement or any of the other Credit Documents at the
time performance of such provision shall be due 



                                      -86-

<PAGE>   93

shall exceed the Highest Lawful Rate, then, automatically, the obligation to be
fulfilled shall be modified or reduced to the extent necessary to limit such
interest to the Highest Lawful Rate, and if from any such circumstance any
Lender should ever receive anything of value deemed interest by applicable law
which would exceed the Highest Lawful Rate, such excessive interest shall be
applied pursuant to the terms hereof to the reduction of the principal amount
then outstanding hereunder or on account of any other then outstanding
Obligations and not to the payment of interest, or if such excessive interest
exceeds the principal unpaid balance then outstanding hereunder and such other
then outstanding Obligations, such excess shall be refunded to the Borrowers.
All sums paid or agreed to be paid to the Agent or any Lender for the use,
forbearance, or detention of the Obligations and other Indebtedness of the
Borrowers to the Agent or any Lender, to the extent permitted by applicable law,
shall be amortized, prorated, allocated and spread throughout the full term of
such Indebtedness, until payment in full thereof, so that the actual rate of
interest on account of all such Indebtedness does not exceed the Highest Lawful
Rate throughout the entire term of such Indebtedness. The terms and provisions
of this SECTION 11.14 shall control over every other provision of this Credit
Agreement, the other Credit Documents, and all agreements among the Borrower,
the Agent and the Lenders.

        11.15     ENTIRE AGREEMENT; SUCCESSORS AND ASSIGNS.

        This Credit Agreement and the other Credit Documents constitute the
entire agreement among the Credit Parties, the Agent and the Lenders, supersede
any prior agreements among them, and shall bind and benefit each of such Persons
and their respective successors and permitted assigns.

        11.16     JOINT AND SEVERAL LIABILITY OF BORROWERS.

                  (a) Each of the Borrowers shall be jointly and severally
        liable hereunder and under each of the other Credit Documents with
        respect to all Obligations, regardless of which of the Borrowers
        actually receives the proceeds of the Revolving Loans or the benefit of
        any other extensions of credit hereunder, or the manner in which the
        Funds Administrator, the Borrowers, the Agent or the Lenders account
        therefor in their respective books and records. Notwithstanding the
        foregoing, (i) each Borrower's obligations and liabilities with respect
        to proceeds of Revolving Loans which it receives or Letters of Credit
        issued for its account, and related fees, costs and expenses, and (ii)
        each Borrower's obligations and liabilities arising as a result of the
        joint and several liability of the Borrowers hereunder with respect to
        proceeds of Revolving Loans received by, or Letters of Credit issued for
        the account of, any of the other Borrowers, together with the related
        fees, costs and 



                                      -87-

<PAGE>   94
         expenses, shall be separate and distinct obligations, both of which are
         primary obligations of such Borrower. Neither the joint and several
         liability of, nor the Liens granted to the Agent under the Collateral
         Documents by, any of the Borrowers shall be impaired or released by (a)
         the failure of Agent or any Lender, any successors or assigns thereof,
         or any holder of any Note or any of the Obligations to assert any claim
         or demand or to exercise or enforce any right, power or remedy against
         the Funds Administrator, any Borrower, any Subsidiary of any Borrower,
         any other Person, the Collateral or otherwise; (b) any extension or
         renewal for any period (whether or not longer than the original period)
         or exchange of any of the Obligations or the release or compromise of
         any obligation of any nature of any Person with respect thereto; (c)
         the surrender, release or exchange of all or any part of any property
         (including without limitation the Collateral) securing payment,
         performance and/or observance of any of the Obligations or the
         compromise or extension or renewal for any period (whether or not
         longer than the original period) of any obligations of any nature of
         any Person with respect to any such property; (d) any action or
         inaction on the part of Agent or any Lender, or any other event or
         condition with respect to any other Borrower, including any such action
         or inaction or other event or condition, which might otherwise
         constitute a defense available to, or a discharge of, such other
         Borrower, or a guarantor or surety of or for any or all of the
         Obligations; and (E) any other act, matter or thing (other than payment
         or performance of the Obligations) which would or might, in the absence
         of this provision, operate to release, discharge or otherwise
         prejudicially affect the obligations of such or any other Borrower.

                  (b) Each Borrower understands and acknowledges that if the
        Agent forecloses judicially or nonjudicially against any Collateral
        consisting of real property, that foreclosure could impair or destroy
        any ability that such Borrower may have to seek reimbursement,
        contribution or indemnification from any other Borrower or Borrowers or
        from others based on any right such Borrower may have of subrogation,
        reimbursement, contribution or indemnification in respect of its joint
        and several liability hereunder. Each Borrower further understands and
        acknowledges that in the absence of this SECTION 11.16(b), such
        potential impairment or destruction of such Borrower's rights, if any,
        may entitle such Borrower to assert a defense to its joint and several
        liability hereunder based on Section 580d of the California Code of
        Civil Procedure as interpreted in Union Bank v. Gradsky, 265 Cal.App.2d
        40 (1968). By executing this Agreement, each Borrower freely,
        irrevocably and unconditionally: (i) waives and relinquishes that
        defense and agrees that such Borrower will be fully liable hereunder and
        under the other Credit Documents even though the Agent may 



                                      -88-

<PAGE>   95

         foreclose judicially or nonjudicially against any real property
         security for the Obligations; (ii) agrees that such Borrower will not
         assert that defense in any action or proceeding which the Agent or any
         of the Lenders may commence to enforce this Agreement; (iii)
         acknowledges and agrees that the rights and defenses waived by such
         Borrower hereunder include any right or defense that such Borrower may
         have or be entitled to assert based upon or arising out of any one or
         more of Sections 580a, 580b, 580d or 726 of the California Code of
         Civil Procedure or Section 2848 of the California Civil Code; and (iv)
         acknowledges and agrees that the Agent and each of the Lenders is
         relying on this waiver in making the Revolving Loan and other
         extensions of credit hereunder, and that this waiver is a material part
         of the consideration which the Agent and each Lender is receiving
         therefor.

                  (c) Each Borrower waives any rights and defenses that are or
        may become available to such Borrower by reason of Sections 2787 to
        2855, inclusive, of the California Civil Code.

                  (d) Each Borrower waives all rights and defenses that such
        Borrower may have because the Revolving Loans and other Obligations are
        secured in part by real property. This means, among other things:

                             (i) the Lenders may collect from such Borrower
                  without first foreclosing on any real or personal property
                  Collateral pledged by such or any other Borrower or any other
                  Person.

                            (ii) If the Agent forecloses on any real property
                  Collateral pledged by any Borrower or any other Person:

                                    (A) The amount of the Obligations may be
                                reduced only by the price for which that
                                Collateral is sold at the foreclosure sale, even
                                if the Collateral is worth more than the sale
                                price.

                                    (B) Lenders may collect from such Borrower
                                even if the Agent, by foreclosing on the real
                                property Collateral, has destroyed any right
                                such Borrower may have to collect from any other
                                Borrower or Person.

         This SECTION 11.16(d) is an unconditional and irrevocable waiver of any
rights and defenses any Borrower may have because the Obligations are secured in
part by real property. These rights and defenses include, but are not limited
to, any rights or defenses based upon Section 580a, 580b, 580d, or 726 of the
California Code of Civil Procedure.

        11.17     JOINDER OF ADDITIONAL BORROWERS.

        Subsequent to the Closing Date, additional wholly-owned Subsidiaries of
MTLM constituting permitted Investments pursuant to SECTION 8.8 may become
joined as Borrowers hereunder and under certain of the other Credit Documents by
executing and delivering to the Agent (i) a joinder agreement in form and
substance satisfactory to the Agent and (ii) such other agreements, documents
and instruments as the Agent shall reasonably deem necessary or desirable in
connection therewith.

These statement 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 the Company's industry consolidation
strategy. As discussed in the Company's annual report for the period ended
March 31, 1997, its quarterly reports for the periods ended June 30, 1997,
September 30, 1997 and December 31, 1997, its proxy statement dated November
20, 1997, and its Registration Statements on Form S-3 effective as of January
14, 1998 and March 12, 1998, some of the factors which could affect the
Company's performance include, among other things; possible inability to
replace short term financing with longer term capital commitments, possible
inability to obtain capital through debt and/or equity placements sufficient to
fund cash requirements under acquisition and merger agreements, risk of
expansion strategy, cyclicality of operating results, price fluctuations,
existing and future debt of the Company, competition in the scrap metal
industry, immediate and future capital requirements, substantial leverage,
reliance on management and principal stockholders, and environmental matters.
