(d) N/A (e) N/A (f) United States 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. 8 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. 9 ITEM 5.

Date: December 3, 2008 Riley Investment Partners Master Fund, L.P. By: Riley Investment Management LLC, its General Partner By: /s/ Bryant R. Riley ---------------------- Bryant R. Riley Managing Member Riley Investment Management LLC By: /s/ Bryant R. Riley ---------------------- Bryant R. Riley Managing Member B. Riley & Co, LLC By: /s/ Bryant R.

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.
