Zarlink Board of Directors Responds to Unsolicited Bid Announcement by Microsemi Corporation

OTTAWA, CANADA--(Marketwire - Aug. 17, 2011) - Zarlink Semiconductor (TSX:ZL) today acknowledged that Microsemi Corporation announced that 0916753 B.C. ULC, an indirect wholly-owned subsidiary of Microsemi, has commenced unsolicited offers to acquire all of the outstanding shares of Zarlink for $3.35 per share and all of the outstanding convertible debentures of Zarlink for $1,367.35 per $1,000 principal amount of convertible debentures. Zarlink advises shareholders and debentureholders not to take any action until further notice.

On July 20, 2011, the Zarlink Board rejected as financially inadequate and opportunistic Microsemi's public non-binding proposal to acquire all of the outstanding shares of Zarlink at the same $3.35 price per share and stated that that price significantly undervalued Zarlink and its future prospects. The Zarlink Board will review Microsemi's unsolicited offer to determine the course of action that it believes is in the best interests of Zarlink and its stakeholders.

Zarlink advises its shareholders and debenture holders not to take any action concerning the Microsemi offers until they have received further communications from the Zarlink Board. The Zarlink Board will be issuing a Directors' Circular in accordance with applicable securities laws which will contain important information for shareholders and debentureholders, including the Board's recommendation as to the action in response to the Microsemi offer that it believes is in the best interest of stakeholders. The Directors' Circular will also be filed on SEDAR with Canadian securities regulators and on EDGAR with the U.S. Securities and Exchange Commission.

Zarlink notes Microsemi's statements in its press release and wishes to clarify that it is Microsemi that has chosen not to participate in Zarlink's strategic review process. Zarlink is disappointed that, despite its repeated invitations, Microsemi has declined to participate in Zarlink's strategic review process on reasonable terms that favour the best outcome for Zarlink and its stakeholders.

The Zarlink Board has deferred the "Separation Time" that would otherwise have occurred as a consequence of the Microsemi offers until a later date to be determined by the Board. The Rights will not be exercisable, nor will certificates representing the Rights be issued, unless and until the "Separation Time" occurs. In spite of the deferral of the Separation Time, the Shareholder Rights Plan remains in full force and effect.
