Mylan Announces Completion of Add-On Offering of Senior Notes

PITTSBURGH, August 13, 2010 — Mylan Inc. (Nasdaq: MYL) today announced that it has completed a private placement of $300 million aggregate principal amount of Senior Notes due 2020. The notes were issued at an issue price of 105.5% with a coupon of 7.875%, or an effective yield to maturity of 7.087%. The notes were issued as additional notes under an existing indenture under which Mylan issued $700 million aggregate principal amount of 7.875% Senior Notes due 2020 on May 19, 2010. The notes issued in this offering and the previously issued 7.875% Senior Notes due 2020 are treated as a single class of notes under the indenture.

Mylan intends to use the net proceeds of this offering to finance a portion of the $550 million purchase price for the previously-announced acquisition of all of the equity of Bioniche Pharma Holdings Limited, a privately held, global injectable pharmaceutical company. If the Bioniche Pharma acquisition is not consummated, Mylan intends to use the net proceeds from the offering for general corporate purposes, which may include repayment of indebtedness or business development opportunities.

The notes were sold only to qualified institutional buyers in the U.S. in reliance on Rule 144A under the Securities Act of 1933, and outside the U.S. to non-U.S. persons in reliance on Regulation S under the Securities Act. The notes are not and will not be registered under the Securities Act, and may not be offered or sold in the U.S. absent registration or an applicable exemption from registration requirements. This press release shall not constitute an offer to sell, or the solicitation of an offer to buy, any securities, nor shall there be any sale of securities mentioned in this press release in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state.

Mylan Inc. ranks among the leading generic and specialty pharmaceutical companies in the world and provides products to customers in more than 140 countries and territories. The company maintains one of the industry’s broadest and highest quality product portfolios supported by a robust product pipeline; operates one of the world’s largest active pharmaceutical ingredient manufacturers; and runs a specialty business focused on respiratory, allergy and psychiatric therapies.
