CAMARILLO, Calif.--(BUSINESS WIRE)--June 11, 2008--Power-One, Inc. (NASDAQ: PWER) today announced that it intends to offer, subject to market and other conditions, $75 million in aggregate principal amount of senior secured convertible notes due June 2013, to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended. Power-One also expects to grant the initial purchaser of the notes a 30-day over-allotment option to purchase up to an additional $5 million in aggregate principal amount of the notes. The notes are expected to pay interest quarterly and to be convertible into shares of Power-One's common stock at a conversion price to be determined. The notes will be secured by a pledge of Power-One's interests in certain of its subsidiaries and other property and assets.

Power-One intends to use the net proceeds from the proposed offering, after deducting the initial purchaser's discount and estimated offering expenses, of approximately $70.5 million (or $75.3 million if the initial purchaser's over-allotment option is exercised in full), to repay in full the $50.2 million outstanding loan, (including interest) to PWER Bridge, LLC, and to use the balance for working capital and general corporate purposes.

The notes being offered and any shares of common stock issuable upon conversion of the notes have not been registered under the Securities Act or any state securities laws and may not be offered or sold in the United States absent registration under, or an applicable exemption from, the registration requirements of the Securities Act or any applicable state securities laws.

This press release shall not constitute an offer to sell or a solicitation of an offer to buy the notes or the common stock issuable upon conversion of the notes nor shall there be any sale of such securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction.
