Sterlite Industries (India) Limited Announcement Regarding Change in Equity to ADS Ratio

On April 26, 2010, Sterlite Industries (India) Limited (the “Company”) announced that the Board of Directors of the Company has, subject to the approval of the Shareholders, recommended:

• a dividend of Rs. 3.75 per equity share, par value Rs. 2 per equity share (the “Rs. 2 Shares”),
• a split of each of the Company’s Rs. 2 Shares into two equity shares, par value Re. 1 per equity share (the “Re. 1 Shares”), and
• a bonus issue of the Company’s Re. 1 Shares (sub-divided) in the ratio of 1:1,

The Company expects that dividend payments to holders of its American Depositary Shares (“ADSs”) shall be made in accordance with the terms of the Company’s Deposit Agreement (the “Deposit Agreement”) by and among the Company, Citibank N.A., as depositary (the “Depositary”) and the holders and beneficial owners of the Company’s ADSs issued thereunder. The payment of dividend is expected by June 16, 2010.

Following the stock split and bonus issue, each Rs. 2 Share held by a shareholder of the Company on the applicable record date will automatically convert into four Re. 1 Shares. On May 24, 2010, the Company notified the Depositary that the Company intends to give effect to the bonus issue and stock split by changing its ADS-to-equity share ratio such that following the distribution of equity shares in connection with the bonus issue and stock split, each ADS would represent four Re. 1 Shares. Each of the Company’s ADSs currently represents one Rs. 2 Share. As a result of the change of its ADS-to-equity share ratio, the Company does not intend to issue additional ADSs or split its ADSs in connection with the bonus issue and stock split.

The Company intends to announce the record and effective date for the bonus issue and stock split following the Annual General Meeting of the Company’s shareholders to be held on June 11, 2010.

In October 2009, the Company issued US$500 million in aggregate principal amount of 4.00% Convertible Senior Notes Due 2014 (the “Notes”). The Company does not expect that the conversion rate of the outstanding Notes will be required to be adjusted as a result of the dividend, bonus issue or stock split, except that if the bonus issue and stock split are approved by the shareholders, then with effect from the effective date of the bonus issue and stock split, the Notes will become convertible into ADSs, each of which will represent four Re. 1 shares.
