re  MTL Recapitalization/Refinancing
    Bank Commitment Letter
    


Ladies and Gentlemen:

     You have advised Bankers Trust Company ("BTCo") and Credit Suisse First
Boston ("CSFB" and, together with BTCo, each, an "Arranger" and, collectively,
the "Arrangers") that Sombrero Acquisition Corp, ("Acquisition Corp."), a
Florida corporation formed by Apollo Management, L.P. and its affiliates
(collectively, "Apollo") and one or more other investors acceptable to BTCo and
CSFB (together with Apollo, the "Equity Investors"), intends to consummate a
recapitalization (such transaction, together with the MTL Merger referred to
below, the "Recapitalization") of MTL, Inc. ("MTL"), as a result of which (x)
the Equity Investors would own approximately 90% of the issued and outstanding
shares of common stock of MTL and (y) the Holdover Shareholders (as defined
below) would own approximately 10% of the issued and outstanding shares of
common stock of MTL.  As part of the Recapitalization, (i) certain existing
shareholders of MTL (the "Holdover Shareholders") would retain equity capital in
MTL with a value of approximately $8.0 million (the "Equity Retention") and (ii)
cash in an aggregate amount of approximately $187.2 million will be distributed
to the existing shareholders of MTL (other than in respect of equity being
retained pursuant to the Equity Retention and net of the exercise of options).
We understand that the Recapitalization shall be effected by means of a merger
of Acquisition Corp. with and into MTL, with MTL as the surviving corporation of
such merger (the "MTL Merger").  We further understand that in connection with
the Recapitalization, certain existing indebtedness of MTL and its subsidiaries
in an aggregate principal amount not to exceed $65.0 million, consisting of
existing capitalized lease obligations, purchase money indebtedness, MTL's
existing 

 
senior credit facilities and certain subordinated indebtedness, will be
refinanced (the "Refinancing").

     We understand that the sources of funds needed to effect the
Recapitalization and the Refinancing, to pay all fees and expenses incurred in
connection therewith and to provide for the ongoing working capital needs and
general corporate requirements of MTL and its subsidiaries shall be provided
solely through (i) at least $60.0 million from the issuance by Acquisition Corp.
of common stock (the "Common Equity Issuance") to the Equity Investors, (ii) at
least $8.0 million provided by the Holdover Shareholders pursuant to the Equity
Retention, (iii) $140.0 million from the issuance by MTL of senior subordinated
notes (the "Senior Subordinated Notes") (or, in the event the Senior
Subordinated Notes are not issued, $60.0 million from the incurrence by MTL of
the Bridge Loan (as defined in the Bridge Loan Commitment Letter of even date
herewith (the "Bridge Loan Commitment Letter")) and (iv) the incurrence by MTL
of the Senior Bank Financing described below (the financing transactions
described in preceding clauses (i), (ii), (iii) and (iv) are herein collectively
referred to as the "Financing Transactions", with the Recapitalization, the
Refinancing and the Financing Transactions being herein collectively called the
"Transaction").

     BTCo and CSFB further understand that the senior secured bank financing
will be in the form of (i) a term loan facility (the "Term Loan Facility") in
the amount of $60.0 million (or, in the event the Senior Subordinated Notes are
not issued, $140.0 million), to be made available to MTL pursuant to a single
drawing on the date of the consummation of the Recapitalization (the "Initial
Borrowing Date") and (ii) a revolving credit facility (the "Revolving Credit
Facility" and, together with the Term Loan Facility, the "Senior Bank
Financing") in the amount of $100.0 million, to be made available to MTL after
the Initial Borrowing Date.  A preliminary summary of terms and conditions of
the Senior Bank Financing is attached as Exhibit A to this letter (the "Summary
of Terms").

     Each of BTCo and CSFB is pleased to advise you of its commitment, on a
several basis and subject to the terms and conditions contained herein and in
the attached Summary of Terms, to provide (x) 50%, in the case of BTCo and (y)
50%, in the case of CSFB, of the Senior Bank Financing.  In connection with the
Senior Bank Financing, BTCo and CSFB shall act as the sole agents (in such
capacity, each, an "Agent" and, collectively, the "Agents") on terms
satisfactory to BTCo, CSFB, MTL and you.  The Arrangers shall manage all aspects
of the syndication of the Senior Bank Financing.

     The Arrangers reserve the right, prior to or after execution of the
definitive credit documentation for the Senior Bank Financing, to syndicate all
or a part of the Senior Bank Financing to one or more financial institutions
(together with the Arrangers, the "Lenders") approved by MTL (which approval
shall not be unreasonably withheld or delayed) that will become parties to such
definitive credit documentation pursuant to a syndication to be managed by the
Arrangers.  You agree actively to assist the Arrangers in achieving a
syndication that is satisfactory to the Arrangers and to you.  Such syndication
will be accomplished by a variety of means, including direct contact 

 
during the syndication between senior management and advisors of Acquisition
Corp. and MTL (including, without limitation, Apollo) and the proposed Lenders.
To assist the Arrangers in their syndication efforts, you hereby agree both
before and after the Initial Borrowing Date (i) to provide and cause your
advisors to provide the Arrangers and the other Lenders upon request with all
reasonable information deemed necessary by us to complete syndication, including
but not limited to, information and evaluations prepared by you and MTL and your
and its respective advisors and (ii) to assist the Arrangers upon request in the
preparation of an Information Memorandum to be used in connection with the
syndication of the Senior Bank Financing, including making available officers of
MTL and its subsidiaries from time to time to attend and make presentations
regarding the business and prospects of MTL and its subsidiaries, as
appropriate, at a meeting or meetings of Lenders or prospective Lenders.

     Each of BTCo's and CSFB's commitment to provide a portion of the Senior
Bank Financing is expressly subject to (a) there not having occurred since
December 31, 1996 any material adverse change in the business, properties,
assets, operations, liabilities, condition (financial or otherwise) or prospects
of MTL and its subsidiaries taken as a whole, both before and after giving
effect to the Transaction and (b) the absence of any material adverse change
after the date hereof in the market for syndicated facilities similar in nature
to the Senior Bank Financing and the absence of any material disruption of or a
material adverse change in financial, banking or capital markets generally, in
each case as determined by BTCo and CSFB in their reasonable discretion.

     To induce the Arrangers to issue this letter, you hereby agree that all
reasonable fees and expenses (including the reasonable fees and expenses of
counsel and consultants) of the Arrangers and their respective affiliates
arising in connection with the preparation, execution and delivery of this
letter and the definitive financing agreements (and our due diligence in
connection therewith) and in connection with the transactions described herein
(the "Transaction Expenses") shall be for your account in the event that the
Recapitalization and/or the Refinancing are consummated; provided, however, that
in the event you or any of your affiliates receives any termination fee or
expense reimbursement payable as a result of the termination of the definitive
agreements relating to the Recapitalization, you shall reimburse from the
aggregate amount of such termination fee and expense reimbursement so received
the Arrangers' and their respective affiliates' Transaction Expenses on a pro
rata basis with all others (including you and your affiliates) claiming expenses
in connection with the transactions described herein.  You further agree,
whether or not the Recapitalization or the Refinancing is consummated, the
Senior Bank Financing is made available or definitive credit documents are
executed, to indemnify and hold harmless each Arranger, its affiliates and each
director, officer, employee, agent and representative thereof (each, an
"indemnified person") from and against any and all actions, suits, proceedings
(including any investigations or inquiries), claims, losses, damages,
liabilities or expenses of any kind or nature whatsoever (other than the
Transaction Expenses, which shall be payable as provided in the first sentence
of this paragraph (and the proviso thereto)) which may be incurred by or
asserted against or involve such Arranger, such affiliate or any such

 
indemnified person as a result of or arising out of or in any way related to or
resulting from the Transaction (or any element thereof), this letter or the
extension of the Senior Bank Financing contemplated by this letter, or in any
way arising from any use or intended use of this letter or the proceeds of any
of the Senior Bank Financing contemplated by this letter and, upon demand, to
pay and reimburse each Arranger, each such affiliate and each indemnified person
for any reasonable legal or other out-of-pocket expenses incurred in connection
with investigating, defending or preparing to defend any such action, suit,
proceeding (including any inquiry or investigation) or claim (whether or not
such Arranger or any such indemnified person is a party to any action, suit or
proceeding out of which any such expenses arise and whether or not any such
action, suit or proceeding is between you and a Arranger or an indemnified
person or between a Arranger or an indemnified person and a third party or
otherwise); provided, however, that you shall not have to indemnify any Arranger
or indemnified person against any loss, claim, damage, expense or liability
which resulted primarily from the gross negligence or willful misconduct of such
Arranger, such affiliate or such indemnified person.  This letter is issued for
your benefit only and no other person or entity may rely thereon.  Neither any
Arranger nor any other Lender shall be responsible or liable to you or any other
person for any consequential damages which may be alleged as a result of this
letter or any failure to provide the Senior Bank Financing.

     Each Arranger reserves the right to employ the services of its affiliates
(including, without limitation, in the case of BTCO, BT Alex. Brown Incorporated
("BTAB")) in providing the services contemplated by this letter and to allocate,
in whole or in part, to such affiliates certain fees payable to the Arrangers in
such manner as the Arrangers and such affiliates may agree in their sole
discretion.  You acknowledge that the Arrangers may share with any of their
respective affiliates (including BTAB), and such affiliates may share with the
Arrangers, any information relating to Acquisition Corp., MTL and their
respective affiliates and subsidiaries (including, without limitation, any non-
public customer information regarding the creditworthiness of such entities) or
the Transaction, subject to the Arrangers' customary treatment of customer
confidential information; provided, that BTCo shall not share such information
with BTAB in its capacity as financial advisor to MTL in connection with the
Recapitalization and related transactions.  You also acknowledge that the
Arrangers and/or any of their respective affiliates may be providing other
services and/or other financing to you in connection with the Transaction and
that this letter relates only to the Senior Bank Financing, with all such other
services and financing to be agreed upon pursuant to other documentation.

     You are not authorized to show or circulate this letter or any portion
thereof to any other person or entity (other than your legal and financial
advisors in connection with your evaluation hereof) until such time as you have
accepted this letter as provided in the penultimate paragraph hereof.  In any
event, neither you nor your affiliates is authorized to disclose the terms of
the related fee letter (the "Fee Letter") without our prior written consent,
unless (and then only to the extent) required by law.  If this letter is not
accepted by you as provided in the penultimate paragraph hereof, you are to
immediately return this letter (and any copies hereof) to the undersigned.

 
     Except as otherwise expressly set forth herein, the provisions of the three
preceding paragraphs shall survive any termination of this letter.

     Each of the Arrangers shall have the right to review and approve all public
announcements and filings relating to the Transaction which refer to BTCo, CSFB
or the other Lenders before they are made (such approval not to be unreasonably
withheld or delayed).

     The willingness of each of BTCo and CSFB to provide their respective
commitments as set forth above will terminate on June 30, 1998, unless
definitive documentation evidencing the Senior Bank Financing, satisfactory in
form and substance to BTCo and CSFB, shall have been entered into prior to such
date and the Initial Borrowing Date shall have occurred.

     If you are in agreement with the foregoing, please sign and return to BTCo
and CSFB the enclosed copy of this letter, together with an executed copy of the
Fee Letter.  This offer shall terminate at 5:00 P.M., New York time, on February
24, 1998 unless a signed copy of this letter, together with a signed copy of the

                     $140.0 million) (the "Term Loan Facility").

Maturity:            The Term Loan Facility will mature on the date (the "Term
                     Loan Facility Maturity Date") that occurs on the sixth
                     anniversary of the Initial Borrowing Date.

Amortizations:  Annual amortization (payable in four equal quarterly
                     installments) of the loans under the Term Loan Facility
                     (the "Term Loans") shall be required in an amount for each
                     such annual period equal to 1% of the initial aggregate

                       of Revolving Loans to the extent in excess of such
                       commitments as so reduced).

                 agreed upon and excluding any equity issued as consideration in
                 connection with, or the proceeds of which are used to effect,
                 Permitted Acquisitions, (d) 75% (or 50%, if the Total Debt-to-
                 EBITDA Ratio is less than a mutually agreed upon level) of

                 "Qualified Preferred Stock" shall mean any preferred stock of
                 the Borrower, the express terms of which shall provide that
                 dividends thereon shall not be required to be paid at any time
                 (and to the extent) that such payment would be prohibited by
                 the terms of the Credit Agreement or any other agreement of the
                 Borrower relating to outstanding indebtedness and which, by its
                 terms (or by the terms of any security into which it is
                 convertible or for which it is exchangeable), or upon the
                 happening of any event (including any change of control event),

                 optional redemption by the issuer thereof) and is not
                 mandatorily redeemable, pursuant to a sinking fund obligation
                 or otherwise, and is not redeemable, or required to be
                 repurchased, at the sole option of the holder thereof
                 (including, without limitation, upon the occurrence of a change
                 of control event), in whole or in part, on or prior to the
                 second anniversary of the Term Loan Maturity Date.

Events of 
Default:         Those typical for these types of facilities and any additional
                 ones appropriate in the context of the proposed transaction
                 including, without limitation, payment, material
                 misrepresentations, covenant defaults, bankruptcy and a Change
                 of Control Event (to be defined).

Assignments and
Participations:  The Borrower may not assign its rights or obligations under the
                 Senior Bank Financing without the prior written consent of the
                 Agents and the Lenders. Any Lender may assign, and may sell
                 participations in, its rights and obligations under the Senior

                 restrictions on the voting rights of the participants
                 and (y) in the case of assignments, to a minimum assignment
                 requirement of $5,000,000 (or to the extent the amount held by
                 such Lender is less than $5,000,000, such lesser amount) and
                 such other limitations as may be established by the
                 Administrative Agent. So long as no event of default exists
                 pursuant to the Senior Bank Financing, the consent of the
                 Borrower shall be required with respect to assignments of Loans
                 (other than assignments to (x) affiliates of the respective
                 Lender or (y) any entity which is already a Lender), such
                 consent not to be unreasonably withheld or delayed. The Senior
                 Bank Financing shall provide for a mechanism which will allow
                 for each assignee to become a direct signatory to the Senior
                 Bank Financing and will relieve the assigning Lender of its
                 obligations with respect to the assigned portion of its
                 commitment.

Governing Law:   The rights and obligations of the parties under the Credit
