NEW YORK, March 12, 2008 — Dow Jones Indexes today announced the Dow Jones-AIG Grains Sub-Index has been licensed to Horizons BetaPro Funds to underlie two leveraged commodity exchange-traded funds. The Horizons BetaPro DJ-AIG(sm) Agricultural Grains Bull Plus ETF and Horizons BetaPro DJ-AIG(sm) Agricultural Bear Plus ETF launched today on the Toronto Stock Exchange.

This is the first time the Dow Jones-AIG Grains Sub-Index will serve as the basis of Canadian ETFs.

“Commodities continue to be a popular choice among market participants seeking to gain exposure to alternative asset classes. Since the launch of the broadly diversified Dow Jones-AIG Commodity Index, we’ve expanded the lineup to include single commodity and sector indexes, which provide specific views of the commodity futures markets. The Dow Jones-AIG Grains Sub-Index is an ideal benchmark of the performance of the corn, soybeans and wheat futures markets,” said Michael A. Petronella, president of Dow Jones Indexes.

The Dow Jones-AIG Commodity Index is a diversified and highly liquid benchmark for the commodities markets. It is composed of futures contracts on 19 physical commodities and was introduced in 1998.

As of the end of the fourth quarter of 2007, there is an estimated $42 billion tracking the DJ-AIGCI, out of a total of approximately $155 billion tracking commodities using long-only index strategies. Index methodology and futures contracts used to calculate the index are published in the DJ-AIGCI Handbook. The handbook can be requested via www.djindexes.com or http://www.aigfp.com.

As of March 11, 2008, the one-year performance of the Dow Jones- AIG Grains Sub-Index is 62.50%.
