Notice to US holders of OctoPlus Shares
The Offer will be made for the securities of a Dutch company and is subject to Dutch disclosure requirements, which are different from those of the United States. Some of the financial information included in this announcement has been prepared in accordance with International Financial Reporting Standards and thus may not be comparable to financial information of US companies or companies whose financial statements are prepared in accordance with generally accepted accounting principles in the United States. The Offer will be made in the United States pursuant to the applicable US tender offer rules and otherwise in accordance with the requirements of the Dutch Public Takeover Decree. Accordingly, the Offer will be subject to disclosure and other procedural requirements, including with respect to withdrawal rights, offer timetable, settlement procedures and timing of payments, that are different from those applicable under US domestic tender offer procedures and law.

The receipt of cash pursuant to the Offer by a US holder of OctoPlus shares may be a taxable transaction for US federal income tax purposes and under applicable state and local, as well as foreign and other tax laws. Each holder of OctoPlus shares is urged to consult his independent professional advisor immediately regarding the tax consequences of acceptance of the offer.

It may be difficult for US holders of OctoPlus shares to enforce their rights and claims arising out of the US federal securities laws, since OctoPlus is located in a country other than the United States, and some or all of its officers and directors may be residents of a country other than the United States. US holders of OctoPlus shares may not be able to sue a non-US company or its officers or directors in a non-US court for violations of the US securities laws. Further, it may be difficult to compel a non-US company and its affiliates to subject themselves to a US court’s judgment.

In accordance with normal Dutch practice and pursuant to Rule 14e-5(b) of the Securities Exchange Act of 1934, Dr. Reddy's or its nominees, or its brokers (acting as agents), may from time to time make certain purchases of, or arrangements to purchase, OctoPlus shares outside of the United States, other than pursuant to the Offer, before or during the period in which the Offer remains open for acceptance. These purchases may occur either in the open market at prevailing prices or in private transactions at negotiated prices. Any information about such purchases will be disclosed as required in the Netherlands, will be reported to the Netherlands Authority for the Financial Markets (Stichting Autoriteit Financiële Markten) and disclosed in the offer memorandum or by press release.
