Forward-Looking Statements

This news release contains forward-looking statements regarding future events or results, including statements regarding Sirenza's current revenue projections for the second quarter ending June 30, 2005. Sirenza cautions readers that such statements are, in fact, predictions that are subject to risks and uncertainties, and that actual events or results may differ materially. Factors that could cause actual events or results to differ materially include, but are not limited to: reduced demand for Sirenza's products at major OEMs as the result of industry consolidation or otherwise; reduced demand for RF components or broadband products in general; possible delays by Sirenza's customers in the implementation of next-generation equipment; Sirenza's ability to successfully develop and release new products which meet customer demands and the acceptance and deployment of those products by Sirenza's intended customers; lower than expected OEM demand for increasing levels of integration; exertion of downward pressure on the pricing of Sirenza's components; Sirenza's lack of market knowledge relative to other participants in new markets into which it has or may diversify; Sirenza's ability to coordinate different development and engineering teams; Sirenza's ability to successfully manage the risks associated with and to grow its aerospace and defense business; Sirenza's ability to successfully differentiate itself from competitors in its markets; Sirenza's reliance on third parties for outsourced manufacturing, packaging and test services and supply; Sirenza's merger and acquisition activities and ability to successfully integrate the assets, personnel, operations and engineering teams and processes of any mergers or acquisitions with Sirenza; and/or Sirenza's ability to realize expected synergies of any mergers or acquisitions and the envisioned benefits to Sirenza. Each and all of these factors could be due to overall general economic or telecommunications market conditions, or conditions in the mobile and fixed wireless and wireline infrastructure markets, or otherwise. Other factors that could cause actual events or results to differ materially from those in the forward-looking statements are included in Sirenza's Annual Report on Form 10-K filed with the Securities and Exchange Commission in March 2005. Sirenza expressly disclaims any current intention to update its forward-looking statements, and the estimates and assumptions associated with them, at any time or for any reason.
