Zarlink Provides Update on Shareholder Rights Plan

OTTAWA, ONTARIO--(Marketwire - July 29, 2011) - Zarlink Semiconductor Inc. (TSX:ZL) today announced that, further to the press release of Zarlink on July 25, 2011 announcing the adoption of a limited duration shareholder rights plan (the "Rights Plan"), the Toronto Stock Exchange (the "TSX") determined on July 27, 2011, in accordance with its rules, to defer its consideration of the acceptance for filing of the Rights Plan until the appropriate securities commission has had the opportunity to consider whether it will initiate proceedings under securities laws with respect to the Rights Plan. The deferral does not affect the operation of the Rights Plan which remains effective in accordance with its terms.

The TSX deferral is typical in situations in which a shareholder rights plan can be perceived to have been adopted in response to a take-over bid that has been made or is contemplated or in situations in which a limited duration shareholder rights plan for which shareholder approval will not be sought is adopted. As previously disclosed, the Rights Plan is intended to allow the Board of Directors to effectively enhance shareholder value and to ensure that all shareholders are treated fairly and equally in connection with any take-over bid for Zarlink. To date, no formal take-over bid has been made.
