ISE and SuperDerivatives Establish Marketing Alliance

The International Securities Exchange (NYSE: ISE) and
SuperDerivatives(R), announced today that the companies have
established a marketing and sales alliance to jointly promote their
products and services. In the coming weeks, the two companies will
proactively reach out to investors about the benefits of this new
relationship.
   SuperDerivatives provides tools that allow accurate pricing and
monitoring of derivative portfolios, including SD-EQ(TM), its equity
options pricing system for options pricing, risk management and
independent revaluations. SD-EQ is designed to be a bridge between the
exchange-traded and over-the-counter (OTC) markets, enabling investors
to easily price options and manage their options on US stocks
denominated in their own currencies. Accurate prices for all equity
options, combined with risk management tools and accurate end of day
revaluations will promote increased transparency in the exotic and OTC
options market.
   "We look forward to working with SuperDerivatives to offer
investors their enhanced options pricing model. While many investors
appreciate the advantages of using equity options to hedge portfolios,
in some cases the lack of transparency for pricing of more exotic, OTC
instruments may minimize their willingness to use them. We believe
that by further promoting innovative pricing models in the market, we
can continue to improve the level of transparency and liquidity in
equity options," states Bruce Goldberg, chief marketing officer of
ISE.
   "ISE, the first all-electronic US equity options exchange, has had
a huge impact in making the market more transparent and accessible.
Similarly, SuperDerivatives has revolutionized pricing in the once
opaque foreign exchange market. Together, we intend to bring the same
benefits to the equity options market. By making accurate option
pricing tools available to everyone through our SD-EQ product, we
believe the market will further expand as all users will be able to
price any US equity option in real-time as accurately as the most
sophisticated traders in the top-tier investment houses" adds David
Gershon, chief executive officer of SuperDerivatives.
