Master Fund, L.P. and 720,973 shares held in managed accounts by its investment

LLC. Mr. Riley is the Chairman and indirect sole equity owner of B. Riley & Co.,
LLC. Includes 32,765 shares owned by B. Riley & Co. Retirement Trust. Because
Mr. Riley, in his role as Trustee of the B. Riley & Co. Retirement Trust,
controls its voting and investment decisions, Mr. Riley may be deemed to have
beneficial ownership of these shares. Includes 8,400 shares of Common Stock
owned by custodial accounts of Mr. Riley's children. Includes 2,000 shares of
Common Stock held in a joint account with Mr. Riley's spouse.

advisory clients, Mr. Riley disclaims beneficial ownership of the non-affiliated
shares.

ITEM 3.         SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.
                --------------------------------------------------

                The source of funding for the purchase of Common Stock was the
general working capital of the respective purchasers. (See the responses set
forth in Row 4 on the cover pages for each Reporting Person.) Some of the shares
are held in margin or leveraged accounts together with other securities, and
part of the purchase price of such shares may have been purchased through margin
borrowing or other leverage.

ITEM 4.         PURPOSE OF TRANSACTION.
                ----------------------

                The Reporting Persons acquired the shares of Common Stock
based on the Reporting Persons' belief that the Common Stock represent an
attractive investment opportunity.

                  On December 3, 2008, RIM sent a letter to the Issuer's Board
of Directors. In the letter, among other things, RIM, while complimenting the
Issuer on its operational improvements, stated its belief that shareholder value
would be best maximized through a sale of the company. RIM encouraged the Issuer
to not only review a sale to a single buyer but also to consider selling the
company in pieces. RIM believes this process, although time consuming and
difficult, may result in each of the Issuer's business unit receiving full value
as opposed to a sale of the company as a whole to a single buyer who may
discount the businesses they do not want. RIM asked that the Issuer begin a
sales process immediately and asked for a board seat. The foregoing description
of the letter is qualified in its entirety by Exhibit A.

                  The Reporting Persons may, from time to time, evaluate various
other alternatives that they might consider in order to influence the
performance of the Issuer and the activities of its Board of Directors.
Depending on various factors, the Reporting Persons may take such actions as
they deem appropriate including, without limitation, engaging in discussions
with management and the Board of Directors of the Issuer, communicating with
other stockholders, making proposals to the Issuer concerning the capitalization
and operations of the Issuer, seeking representation on the Board of Directors,
purchasing additional shares of Common Stock or selling some or all of their
shares of Common Stock or seeking to make a significant equity investment or to
otherwise acquire the Issuer.

                  The Reporting Persons may determine to change their investment
intent with respect to the Issuer in the future. The Reporting Persons intend to
vote their respective shares of Common Stock individually as each Reporting
Person deems appropriate from time to time. In determining whether to sell or
retain their shares of Common Stock, the applicable Reporting Person will take
into consideration such factors as it deems relevant, including without
limitation Issuer's business and prospects, anticipated future developments,
existing and anticipated market conditions, general economic conditions, capital
requirements of the Reporting Person and other opportunities available to the
Reporting Person. The Reporting Persons reserve the right to acquire securities
of the Issuer in the open market, in privately negotiated transactions, or
otherwise, to dispose of all or a portion of its holdings in Issuer's
securities, or to change their intention with respect to any or all of the
matters referred to in this Item 4.

                  Except as stated in response to this Item 4, the Reporting
Persons have no current plans or proposals with respect to the Company or its
securities of the types enumerated in paragraphs (a) through (j) of Item 4 to
the form Schedule 13D promulgated under the Act.

                                [RIM Letterhead]

December 3, 2008

Board of Directors
Magnetek, Inc.
N49 W13650 Campbell Drive
Menomonee Falls WI 53051

To the Board of Directors:

As you may know, Riley Investment Management LLC has been an investor in
Magnetek for over 7 years. During this time, we have seen the Company transform
itself from a bloated undisciplined company to a business with a significant
presence in strong niche markets. While we have been pleased with the Company's
operational performance, the devotion of the management team and the improved
balance sheet, we strongly believe that the best course of action for the
shareholders would be to immediately begin a sale process of the Company. We
believe that this process could garner a price at significant premiums to the
current market capitalization and attract multiple large bidders.

The Company's most recent quarter was impressive. Revenues of $26.4 million were
up 16%, your book to bill was 118% and your cash increased to $16 million. Most
importantly, operating income almost doubled from last year. These numbers were
particularly strong given your investment in the alternative wind business. We
applaud your improvements to the operations.

However, we believe that your market size, market capitalization and ongoing
pension liability will make it difficult for your shareholders to receive fair
value on the open market. Conversely, it is our opinion that larger corporations
who have long been interested in the Magnetek brand and niche markets will be
willing to acquire the Company's businesses at significantly higher values than
the current market capitalization.

Moreover, we believe that value may be best maximized by selling your businesses
in pieces as opposed to a total sale. This process, while perhaps more time
consuming and difficult, can result in each business unit receiving full value
as opposed to a sale to a single buyer who will discount the pieces that they
don't want.

We urge you to formally begin this process right away. Additionally, as a large
shareholder with a significant track record in creating shareholder value we
request a board seat immediately. Given our involvement in the sales of
companies with several business units (i.e. Alliance Semiconductor, Celeritek),
we believe we can be a great help in this process. Additionally, it is our
experience that a large shareholder involved not only adds a sense of urgency
but also creates an environment in which service fees are more carefully
reviewed and possible options are more broadly considered.


                                      A-1





We have written many letters to the board over the last few years and made many
requests of management. This one is unique in that we hold the Board and
management of Magnetek in high regard. However, our view that shareholders would
recognize more value through a formal sales process is strong, and we hope that
this message is well received. We will continue to evaluate all of our options
as it relates to our Magnetek position.

Sincerely,

Riley Investment Management LLC
