ISE Partners with UBS to Launch Two New Exchange-Traded Notes (ETNs)
Based on ISE’s Solid State Drive™ Index

NEW YORK, September 21, 2011 – The International Securities Exchange (ISE) has launched the ISE Solid State Drive™ Index (Ticker: BYT), a benchmark that allows investors to track companies actively involved in the solid state drive segment of the electronic storage industry. To be eligible for inclusion in the index, companies must either produce finished solid state drives or supply components used to manufacture solid state drives.

ISE has also partnered with UBS to launch two exchange-traded notes linked to this new index: ETRACS ISE Solid State Drive Index ETN (Ticker: SSDD) and the ETRACS Monthly 2xLeveraged ISE Solid State Drive Index ETN (Ticker: SSDL). These are the first such ETNs providing investors with exposure to this segment of the electronic storage industry. Both products began trading on NYSE Arca on September 15, 2011.

“The launch of the ISE Solid State Drive Index and these respective ETNs demonstrates the ongoing development of our successful collaboration with UBS,” said Kris Monaco, Head of New Product Development at ISE. “These additions to our product offering of both strategy-based and futures-based indexes further expand our portfolio of indexes that serve as actionable investment strategies for exchange-traded products (ETPs).”

These two new products are part of a portfolio of four UBS-issued ETNs based on ISE indexes. T here are currently 15 ETPs based on ISE’s proprietary indexes, including 11 ETFs. Aggregate assets under management (AUM) for the associated funds is approximately $1 billion.

Historical index values, real-time pricing information and methodology guides for ISE indexes are available on ISE’s website at www.ise.com/index .
