NOTE 12: SUBSEQUENT EVENTS

On October 31, 2012, we issued $60.0 million aggregate principal amount of 4.50% convertible senior subordinated notes due November 15, 2017, and on November 6, 2012 we issued an additional $10.0 million aggregate principal amount of 4.50% convertible senior subordinated notes due November 15, 2017 pursuant to an over-allotment provision (“4.50% notes”). These notes are convertible into shares of our common stock at a conversion rate of 607.1645 shares per $1,000 principal amount of notes, a conversion price of approximately $1.65 per share. We may not redeem the notes prior to their maturity date although investors may convert the 4.50% notes into Quantum common stock until November 14, 2017 at their option. In addition, since purchasers are qualified institutional investors, as defined in Rule 144A under the Securities Act of 1933 (“Securities Act”), the 4.50% notes have not been registered under the Securities Act. We will pay 4.50% interest per annum on the principal amount of the notes semi-annually on May 15 and November 15 of each year beginning in May 2013. Interest began to accrue on October 31, 2012. The terms of the 4.50% notes are governed by an agreement dated October 31, 2012 between Quantum and U.S. Bank National Association. The 4.50% notes are subordinated to any existing indebtedness and other liabilities.

We repaid all outstanding borrowings under the WF credit agreement with $49.5 million of the proceeds from the 4.50% notes on October 31, 2012.
