Employee FAQs #6

1. Is there an ESPP program in CSR and if so, will it be effective for all Zoran employees? If not, will there be compensation to the employees for the loss of this benefit?

• CSR has authorization to operate ESPP-like plans in the UK and US.

• CSR is reviewing these plans along with overall benefit programs globally for the merged company and decisions will be communicated post closing.

2. Many employees are leaving Zoran and it is difficult to attract new candidates. Something will need to change in the atmosphere. Does CSR have a plan for this?

• CSR has an active recruitment program. Throughout the year different CSR locations also participate in graduate fairs and opening days. PR is also a valuable tool in raising awareness locally when combined with our global Social Responsibility program, CSR is receiving recognition as an organisation that people want to be part of.

• CSR strongly believes in the engagement and development of its people. We have invested significantly over the past few years in both the measurement of employee engagement and in learning and development solutions that support this goal. Over the coming year, we will be continuing to work with teams and individuals to help engage and integrate them into CSR, and to offer appropriate opportunities for structured development, that will help to progress both technical and professional skills. We believe this will further encourage people to engage with the growing and maturing business that CSR is becoming and, as a result, help us to retain the fantastic talent that we have within the business.

3. Zoran has had a flat headcount the last few years; are there any plans to grow and develop the business and, as a result, grow the company?

• The overall goal when companies merge is to achieve synergies and effectively leverage all resources so that the combined company can become more competitive and grow in its markets. This does not happen immediately, but that is the long term direction for the new combined company. Company growth may or may not depend on the growth of the total headcount, but rather the redeployment and best use of today’s headcount.

4. Will underwater options convert?

• Yes, as of the closing of the transaction, CSR will assume each outstanding stock option to acquire Zoran stock and each restricted stock unit, or RSU, with respect to Zoran stock.

5. Please explain how shares, RSUs and options will convert.

• Shares

• Each share of Zoran stock will convert into the right to receive a combination of $6.26 in cash and 0.14725 CSR ADSs (equivalent to 0.589 CSR ordinary shares, as each CSR ADS will represent four CSR ordinary shares). Fractional CSR ADSs will be paid in cash.

• For example, 1,000 Zoran shares that you acquired through the ESPP or vesting of RSUs would convert into

• $6,260 (1,000 x $6.26) in cash and

• 147 CSR ADSs (1,000 x 0.14725)

• RSUs and options

• Each outstanding and unexercised stock option to acquire Zoran stock and each RSU with respect to Zoran stock will be assumed by CSR and converted into options or RSUs for CSR equity.

• The exchange ratio for awards converted to CSR ADSs (applicable to employees outside India and Europe) will be (1) 0.14725 plus (2) a ratio representing the equivalent in CSR ADSs of the $6.26 cash portion of the merger consideration, calculated based on the trading price for CSR ordinary shares on the day before the closing of the merger.

• The exchange ratio for awards converted to CSR ordinary shares (applicable to employees in India and Europe) will be (1) 0.589 plus (2) a ratio representing the equivalent in CSR ordinary shares of the $6.26 cash portion of the merger consideration, calculated based on the trading price for a CSR ordinary share on the day before the closing of the merger.

• Example for options converted to CSR ADSs: assuming the closing price of CSR ordinary shares on the day before the closing of the merger is the equivalent of $5, an option for 1,000 shares of Zoran stock with a strike price of $8 would convert into an option for 460 CSR ADSs with a strike price of $17.39, calculated as follows:

• The exchange ratio per share of Zoran stock subject to the option would be 0.46025, calculated as 0.14725 plus 0.313 (the quotient of $6.26 divided by $20, where $20 represents the value of a CSR ADS, which represents four CSR ordinary shares)

• The number of CSR shares subject to the option would be 460, determined as 1,000 x 0.46025, rounded down.

• The strike price per CSR ADS would be $17.39, calculated as $8 ÷ 0.46025, rounded up.

• Example for RSUs converted to CSR ADSs: again assuming the closing price of CSR ordinary shares on the day before the closing of the merger is the equivalent of $5, RSUs for 1,000 Zoran shares would convert into

RSUs for 460 CSR ADSs, calculated as 1,000 x 0.46025 (the exchange ratio as determined in the previous bullet).

• The actual exchange ratio used to convert your awards will depend on the closing price of CSR ordinary shares and the pound/dollar exchange rate on the day before the closing of the merger.

• The vesting schedules and other terms of Zoran options and RSUs will not change.

• For full details, please see CSR’s Form F-4 filing with the U.S. Securities and Exchange Commission, which contains Zoran’s draft proxy statement for the transaction, at http://sec.gov/Archives/edgar/data/1368358/000119312511182948/df4a.htm

6. Has there been any resolution to the Israel tax related issues identified earlier in the filings?

• We expect to receive rulings from the Israeli Tax Authority regarding the Israeli tax issues before the closing of the merger.

• Please see the revised proxy statement for further details.

• We will provide you additional updates when the Israeli Tax Authority has finalized its position.

7. What are the tax implications related to the cash element of the deal for employees with RSUs or options?

• The tax implications will be based on the tax laws that are applicable based on location of employment, such as China, Israel, or U.S.

• Please check with your personal tax advisor, who should be able to advise you regarding the tax implications for your location.
