To All Zoran Employees,

I am pleased to announce that Zoran has signed an agreement to merge with CSR, a leader in Bluetooth and GPS solutions for handsets, automotive, consumer electronics, PCs and health and fitness markets. A copy of the press release issued earlier today can be accessed on the Zoran web site at www.zoran.com

Together we will provide differentiated, integrated product lines to enhance the end user experience in a broad range of devices such as handsets, audio, automotive, entertainment and lifestyle products by offering platform solutions that include connectivity, location-based technologies, image processing and embedded software.

With CSR’s complementary, synergistic, and connectivity-oriented product portfolio, we expect to be able to accelerate the adoption of emerging wireless media and connected home entertainment applications to our served markets. This transaction also meaningfully increases both our scale and global reach, which will enable us to reduce costs, improve operations, efficiently support our customer base, and ultimately create value for our shareholders.

Importantly, we believe that this combination will offer an even more promising future for Zoran employees as part of a larger, better positioned company. We look forward to beginning a new chapter of growth and success with CSR.

We are extremely pleased that the Zoran team will be joining CSR. We look forward to working with the innovative team that has contributed new wireless and location-based technology solutions to our industry. In addition, we believe that with industry-leading customers, the combined company will benefit from the integration of our technologies and multiple cross-selling opportunities that can provide profitable growth for both the near term and in the future.

We expect the transaction to close in the second quarter of 2011, subject to CSR and Zoran shareholder, regulatory and other customary closing approvals. Until then, both companies will continue to operate as separate companies and it will remain business as usual at Zoran. You will hear more about the acquisition at the upcoming Communication Meeting at your local site.

On Monday 21^st February 2011 we intend to broadcast a live video/audio webcast to our investors and analysts. The presentations and Q&A sessions can be accessed below:

Today’s announcement has the potential to lead to increased interest in our company and it is important that we speak with one voice on this matter. If you receive any inquiries from the media or other interested third parties, please refer them to Betty Watkins.

I want to take this opportunity to acknowledge you, our innovative employees; your collective achievements have made today’s announcement possible. I thank you all for your continued dedication and please keep up the great work.
