Tethys Technology Announces Significant Options Trading Enhancements to its
Execta(TM) EMS Platform

Tethys adds enhanced options trading functionality to its Execta(TM) execution
management platform

NEW YORK, April 27 /PRNewswire/ -- Tethys Technology, Inc. a leading provider
of high-performance global multi-asset trading software and analytics,
announced today it has released a powerful new module for options auto-quoting
and centralized risk managed trading as an extension of its Execta execution
management system. The new options module enables users to instantaneously
take advantage of market opportunities in an automated fashion and to
efficiently manage risk on large portfolios of options.

Tethys' Execta(TM) EMS Platform is the most powerful and flexible
broker-neutral algorithmic trading and portfolio management solution available
today. It supports global trading in equities, options, futures and F/X. With
the release of the new module, Execta has further solidified its rating as the
top institutional options trading platform.

"Rising volatility over the last year has resulted in a surge in activity for
volatility based investment and hedging strategies. Increasing market data
rates and fast-moving, fragmented markets have made managing options orders
and hedges a significant challenge. Execta Options Spread Trading and Execta
Auto-Quote strategies allow managers and traders to automate this process to
improve execution performance and lower risk," says Nitin Gambhir, CEO of
Tethys. "In addition our Options Portfolio module provides the ability to
monitor all the 'greeks' and trade vega and delta exposures in a unique manner
that enhances execution efficiency and reduces risk."

Execta Users can upload their fair value volatility curves via text file, API
or link to Excel, then auto-quote on one or both sides of the market using
either embedded risk management and quote price adjustment controls or create
custom logic with our high performance scripting language. Traders can also
specify complex multi-leg spread trades to execute on an automated or
semi-automated basis to achieve their defined spread limits, subject to a
variety of user specified execution and performance constraints

"Options traders can especially benefit from automated algorithmic solutions
that increase their span of control to capture opportunities while containing
their risks across a large universe of available contracts and along the
volatility curve. Tethys has created a sophisticated options trading and
auto-quoting solution that is seamlessly integrated with its world-class
algorithmic trading and smart order routing capabilities," said Andrew Marks
de Chabris, Director of Strategy and Sales at Tethys. "The Execta EMS
comprises a powerful options trading toolset and offers a flexible, low
latency technology environment designed to satisfy even the most demanding
trading operations."
