The conversion rate of the Notes, and the corresponding conversion price, will be subject to adjustment for certain events, but will not be adjusted for accrued interest. In addition, following certain corporate transactions that occur on or prior to the maturity date for the Notes, VIVUS will increase the conversion rate for a holder that elects to convert its Notes in connection with such a corporate transaction.VIVUS may not redeem the Notes prior to the maturity date for the Notes, and there is no sinking fund provided for the Notes. If VIVUS undergoes a fundamental change prior to the maturity date for the Notes, holders may require VIVUS to purchase for cash all or any portion of their Notes at a fundamental change purchase price equal to 100% of the principal amount of the Notes to be purchased, plus accrued and unpaid interest to, but excluding, the fundamental change purchase date. The capped call transaction to be entered into between VIVUS and the hedge counterparty is expected generally to reduce the potential dilution and/or offset potential cash payments in excess of the principal amount of converted Notes upon conversion of the Notes near maturity in the event that the market price of VIVUS's common stock, as measured under the terms of the capped call transaction, is greater than the strike price of the capped call transaction, which initially corresponds to the conversion price of the Notes, and will be subject to anti-dilution adjustments similar (although not identical) to those applicable to the conversion rate of the Notes. However, if the market price of the VIVUS's common stock, as measured under the terms of the capped call transaction, exceeds the cap price of the capped call transaction, the cash or number of shares of common stock VIVUS expects to receive upon exercise of the capped call transaction will be capped based on the amount by which the cap price exceeds the strike price of the capped call transaction. The capped call transaction provides for exercise upon final conversion under the Notes and interim conversion dates under the Notes will not entitle VIVUS to make corresponding exercises under the capped call transaction, but will instead result in a partial early termination of the capped call transaction.
