  Shareholder Rights Law Firm Johnson & Weaver, LLP Announces Investigation of
  Power-One Inc. Proposed Acquisition by ABB Ltd.

Business Wire

SAN DIEGO -- April 22, 2013

Shareholder Rights Law Firm Johnson & Weaver, LLP is investigating whether
members of the board of directors of Power-One Inc. (Nasdaq:PWER) breached
their fiduciary duties in connection with the proposed acquisition by ABB Ltd.

On April 22, 2013, ABB announced that it had entered into a definitive merger
agreement to acquire all outstanding shares of Power-One for $6.35 per share.

The investigation will determine whether the board of directors breached their
fiduciary duties to stockholders by failing to satisfactorily shop the company
before entering into this agreement. Jim Baker, lead analyst for Johnson &
Weaver, stated that, "ABB’s offer appears to be inadequate and not in the best
interest of Power-One's shareholders." In particular, Baker noted that
Power-One is debt free, has over $266 million in cash and has doubled its
market share in a key segment of the business over the last several years.

If you are a Power-One shareholder and are interested in learning more about
the investigation or your legal rights and remedies, please contact lead
analyst Jim Baker (jimb@johnsonandweaver.com) at 619-230-0063.
