On February 7, 2013, Accuray Incorporated ("Accuray") announced the pricing of its offering of $100 million aggregate principal amount of its 3.50% Convertible Senior Notes due 2018 (the "Notes") to certain qualified institutional buyers (collectively, the "QIBs"). The Notes were offered and sold to the QIBs (the "Offering") pursuant to Rule 144A under the Securities Act of 1933, as amended (the "Securities Act"). Accuray received net proceeds of approximately $96.1 million from the Offering, after deducting the initial purchasers' discount and commission and the estimated expenses of the Offering payable by Accuray. The closing of the Offering is expected to occur on February 13, 2013. Accuray has also granted to the initial purchasers of the notes the right to purchase up to an additional $15 million aggregate principal amount of notes.

The Notes will be governed by an indenture between Accuray and The Bank of New York Mellon Trust Company, N.A., as trustee (the "Indenture"), to be dated February 13, 2013.

The Notes will bear interest at a rate of 3.50% per year, payable semi-annually in arrears in cash on February 1 and August 1 of each year, beginning on August 1, 2013. The Notes will mature on February 1, 2018, unless earlier repurchased or converted.

The Notes are convertible, as described below, into common stock of Accuray at an initial conversion rate equal to 187.6877 shares of common stock per $1,000 principal amount of the Notes, which is equivalent to a conversion price of approximately $5.33 per share of common stock, subject to adjustment.

Holders of the Notes may convert their Notes at any time until the close of business on the business day immediately preceding the maturity date.

Holders of the Notes who convert their Notes in connection with a make-whole fundamental change, as defined in the Indenture, may be entitled to a make-whole premium in the form of an increase in the conversion rate. Additionally, in the event of a fundamental change, as defined in the Indenture, holders of the Notes may require Accuray to purchase all or a portion of their Notes at a fundamental change repurchase price equal to 100% of the principal amount of Notes, plus accrued and unpaid interest, if any, to, but not including, the fundamental change repurchase date.
