Employee FAQs #5

1. Now that there is a revised merger Agreement, what are the steps that need to be completed to close the transaction? And what is the projected close date?

• Zoran’s June 16, 2011, 8-K filing with the SEC lists specific conditions to close the merger

• Both companies must file proxy statements that explain the details of the transaction and set a voting date for shareholders

• Shareholders of both companies must vote to approve the transaction

• Our expectation is that the transaction will close in mid Q3

2. What does the revised merger Agreement mean for Zoran stockholders?

• Under the revised terms, Zoran stockholders will receive a cash component, thereby increasing the certainty of the price to be realized, while still retaining upside in the combined company’s larger scale and synergies through a stock component.

3. Where are the synergy numbers coming from? It appears as if they have risen from $50M to $100M? Also, did Zoran really cut $30M in costs already?

• In the February transaction announcement – CSR announced Synergy target of $50M for 2012, which they stated at the time was in addition to ongoing cost reduction programs at Zoran

• In the June announcement, CSR re-iterated the $50M synergy target and made explicit mention of an additional $50M from two sources:

• $30M annual savings due to Zoran’s expense cutting. This is a result of steps undertaken by Zoran this month and earlier this year, relative to Zoran’s expense level in Q1 2011 and reductions through the end of this year.

• $20M increase to the original $50M savings target, identified during integration planning. See next question.

• It is important to note that not all the synergies come from the Zoran business - $15M is targeted from third-party suppliers (part of “cost of sales”) and some will come from the CSR side.

4. The additional $20M savings that Joep mentioned – does it include closing Zoran product lines and is there a target number of headcount to be reduced?

• CSR and Zoran recognize that some re-shaping of the combined businesses will be necessary. It is still too early to make definitive statements on individual business areas and headcount, as this will be worked through during the integration planning.

5. What about DVD and STB, were they mentioned on the video webcast?

• Yes, on the call Joep said “there are other opportunities in IPs such as DVDs and set-top boxes.”

• STB, like DVD, is not listed on the slide addressing the leading market positions since STB is not a market leading product line.

• As mentioned in the previous question, as part of the integration process we are working on the decisions and planning for our future individual businesses including STB and DVD.

6. “Resizing” was mentioned – is it symmetrical (both CSR and Zoran) or only Zoran.

• The resizing will be done by looking at both companies and trying to identify the most effective opportunities for resizing. We do not know yet the conclusion of this process.

7. Are the actions taken at ZCO, including headcount reductions, the last ones or are we expected to have more within Zoran?

• At this time, we do not have any further such plans; however, we will continue the on-going evaluation process required to enhance our efficiency and effectiveness.

8. What is the commitment to the employees? When they will know if they will stay or go?

• Our goal is to be able to let all employees know within eight weeks following the close of the merger of their future roles or timing for transitioning of responsibilities. This will depend on the progress achieved through the work of the integration teams.

9. What happens with our employee stock options? Does it make any difference if they are vested, unvested or underwater? What about our outstanding RSUs?

• In the merger each Zoran share will convert into the right to receive a combination of 0.14725 CSR ADSs (which will be equivalent to 0.589 CSR shares) and $6.26 in cash.

• As of the closing of the transaction, each outstanding and unexercised stock option to acquire Zoran common stock and each restricted stock unit, or RSU, with respect to Zoran common stock will be assumed by CSR.

• The assumed options and RSUs will be converted into options or RSUs for either CSR ADSs or CSR ordinary shares, at the election of CSR.

• The number of CSR ADSs or CSR ordinary shares issuable for each converted option or RSU will equal the number of Zoran common shares subject to the award multiplied by an exchange ratio derived from the merger consideration.

• The exchange ratio for awards settled in CSR ADSs is 0.14725 plus the quotient obtained by dividing (x) $6.26 converted to pounds, by (y) the product of four (4) multiplied by the trading price for CSR ordinary shares on the day prior to the merger.

• The exchange ratio for awards settled in CSR ordinary shares is 0.589 plus the quotient obtained by dividing (x) $6.26 converted to pounds, by (y) the trading price for a CSR ordinary share on the day prior to the merger.

• In addition, the per share exercise price of each converted option will be adjusted by dividing the current exercise price by the CSR ADS exchange ratio or the CSR ordinary share exchange ratio, depending on which security is issuable upon exercise, with the result rounded up to the nearest whole cent.

• We expect that employees outside Europe and India will have their Zoran options and RSUs converted to options and RSUs for CSR ADSs, while employees in Europe and India will have their Zoran options and RSUs converted to options and RSUs for CSR ordinary shares.

10. What happens if shareholders do not approve? What will be our business strategy, operation cost strategy and plan to find other opportunities?

• If there is no transaction, then we will continue to focus on improving our performance on all fronts as we have been doing.

• We are constantly looking for the best way to enhance our strategic and operational position and to benefit from opportunities to create profitable growth. We will continue to do that.

11. Will CSR change to a new name or remain CSR after the merger?

• The combined company is expected be known as CSR.

12. How will the new company’s global offices be combined?

• The integration team is evaluating leases, space needs and requirements for combining the legal entities of both organizations

• The plan for the best use of global office space will be announced after the close

13. Will compensation and benefits change after the merger?

• CSR’s compensation and benefits are very similar to Zoran’s

• These topics are being considered as part of the integration plan

14. Will we sign new employee contracts?

• An integration team made up of members of both companies has been formed to work through areas such as employee benefits, compensation, and employment status, based on local labor law requirements.

• We will let you know once the integration team completes it work and submits it recommendations
