Charlesbank Increases Purchase Price for DEI Holdings

Vista, CA – June 19, 2011 – DEI Holdings, Inc. (PinkSheets: DEIX.PK) today announced that funds affiliated with Charlesbank Capital Partners have agreed to acquire all of the outstanding common shares of DEI Holdings at an increased price that is expected to result in a per share consideration of approximately $4.45 - $4.47 in cash, subject to certain terms and conditions.

As previously announced, DEI Holdings entered into a definitive merger agreement on May 12, 2011 to be acquired by Charlesbank in an all-cash transaction. Under the original terms of the merger agreement, DEI Holdings shareholders would have received approximately $3.79 - $3.80 per share in cash. DEI Holdings subsequently received a non-binding written proposal from Gibson Guitar Corp. to be acquired for approximately $4.47 per share in cash, subject to certain terms and conditions. The Gibson proposal indicated that it intended to finance the entire purchase price with debt financing. After learning of the Gibson proposal, Charlesbank offered to match the Gibson proposal, subject to the transaction being approved by DEI Holdings’ shareholders by 5:00 p.m., Eastern time, on June 20, 2011.

Consistent with its fiduciary duties, the DEI Holdings Board of Directors carefully reviewed the Gibson offer and discussed the merits and risks associated with completing such a transaction. Among other factors, the Board of Directors considered Gibson’s need to conduct additional due diligence, the fact that Gibson’s proposed debt financing was subject to numerous conditions outside the control of DEI Holdings, and the expected delay in closing on Gibson’s offer. Based on its review, the Board of Directors determined that the Gibson proposal presented a high degree of uncertainty and execution risk when compared to the likelihood of completing a transaction with Charlesbank on an expedited basis.

The DEI Holdings Board of Directors, after consultation with its independent financial advisor and outside legal counsel, determined that acceptance of Charlesbank’s increased price is advisable and in the best interests of the company’s shareholders. As a result, DEI Holdings entered into an amendment to the merger agreement with Charlesbank on June 19, 2011, a copy of which is available at www.deiholdings.com. The Board of Directors recommends that shareholders vote for the adoption of the merger agreement, as amended, and approval of the merger at the special meeting of shareholders scheduled for Monday, June 20 at 10:00 a.m. Pacific time.
