FOURTH AMENDMENT TO CREDIT AGREEMENT
                         ------------------------------------

    THIS AMENDMENT is entered into effective as of June 30, 1996, between
MAGNETEK, INC., a Delaware corporation ("BORROWER"), certain Lenders,
NATIONSBANK OF TEXAS, N.A. ("AGENT"), as Agent for Lenders, and CIBC INC., THE
FIRST NATIONAL BANK OF CHICAGO, and LTCB TRUST COMPANY as Co-Agents for Lenders.

    Borrower, Agent, Co-Agents, and certain Lenders are party to the Credit
Agreement (as renewed, extended, and amended, the "CREDIT AGREEMENT") dated as
of March 31, 1995, providing for a $225,000,000 revolving credit facility, which
facility has been reduced to $200,000,000, and a $75,000,000 term loan, which
term loan has been repaid.  Borrower, Agent, and Lenders have agreed, upon the
following terms and conditions, to amend the Credit Agreement to provide for,
among other things, (a) the reduction of the Commitments for the Revolving
Facility to $170,000,000, and (b) changes to certain pricing terms and financial
covenants.

    Accordingly, for adequate and sufficient consideration, Borrower, Agent,
and Determining Lenders agree as follows:

    1.   TERMS AND REFERENCES.  Unless otherwise stated in this amendment (a)
terms defined in the Credit Agreement have the same meanings when used in this
amendment and (b) references to "SECTIONS," "SCHEDULES," and "EXHIBITS" are to
the Credit Agreement's sections, schedules, and exhibits.

    2.   AMENDMENT TO CREDIT AGREEMENT.  The Credit Agreement is amended
effective as of June 30, 1996, as follows:

         (a)  The recital paragraph of the Credit Agreement is entirely amended
    as follows:

              BORROWER ORIGINALLY REQUESTED THAT LENDERS EXTEND CREDIT TO
         BORROWER NOT TO EXCEED A TOTAL OUTSTANDING PRINCIPAL AMOUNT OF
         $300,000,000 (AS THAT AMOUNT MAY BE REDUCED BY CERTAIN BORROWING BASE
         RESTRICTIONS) TO BE USED BY BORROWER AS PROVIDED IN SECTION 7.1 AND
         ALLOCATED AS (A) A TERM LOAN OF $75,000,000 (THE "TERM LOAN") TO BE
         FUNDED BY LENDERS ON THE CLOSING DATE, WHICH HAS BEEN REPAID, AND (B)A
         REVOLVING-CREDIT FACILITY OF $225,000,000, WHICH HAS BEEN REDUCED TO
         $170,000,000 (THE "REVOLVING FACILITY"), TO BE FUNDED BY LENDERS FROM
         TIME TO TIME IN A COMBINATION OF ADVANCES AND LETTERS OF CREDIT.
         LENDERS ARE WILLING TO EXTEND THE REQUESTED CREDIT ON THE TERMS AND
         CONDITIONS OF THIS AGREEMENT.

         TO BE 2.25% FOR LIBOR-RATE BORROWINGS AND 1.00% FOR BASE-RATE

         (c)  SECTION 1.1 is amended by adding or entirely amending the
    following terms:

         INCLUDED IN THE CALCULATION OF EBITDA.

              EXCLUDED CHARGES MEANS, WITH RESPECT TO THE DETERMINATION OF
