`
`preexisting systems, to send orders without risk of error required multiple steps. To the
`extent they permitted one—click order entry, the trader risked having the order sent in at an
`incorrect price if the prices changed on the screen at the moment the trader clicked. MD
`Trader also provided the ability to see working orders in the same window in which the
`trader was viewing market information and trading. In addition, MD Trader had a unique
`one click recentering feature that allowed a trader to easily bring the market back to the
`center of the trading window in a volatile market. This allowed the trader to set a point
`of reference from which to view the market going forward.
`
`I had never seen any of the features described above in a trading application
`7.
`before seeing MD Trader.
`
`Because of the unique features discussed above, MD Trader has been a
`8.
`revolutionary product providing great benefit to electronic traders. The main benefit is
`speed. Because of its more intuitive display and its fast order entry, MD Trader allows
`traders to react quicker and enter orders with less error. The previous systems were far
`slower and much more labor intensive. When I first saw MD Trader, I as struck by how
`different it was than the many existing systems available at the time. It was not just an
`incremental improvement. Another benefit of MD Trader is that it is far easier to use and
`learn, especially for new traders.
`
`Easyscreen initially responded to TT’s MD Trader with a vertical screen in which
`9.
`the market prices were displayed vertically. The problem with this initial response was
`that it did not keep the prices fixed on the screen. The best bid and best ask prices were
`still displayed at designated locations on the screen. Because of this, market movement
`could not be visualized and it still had the same order entry problems as the previous
`
`systems.
`
`Over the years, most every independent software vendor (“ISV”) has replicated
`10.
`MD Trader.
`I have been involved with many meetings or demonstrations in which
`representatives of ISVs have tried to sell their trading applications.
`I recall that these
`sales representatives would often describe their offerings as something similar to or just
`like TT’s MD Trader.
`
`I declare under penalty of perjury that the foregoing is true and correct. Executed on
`
`August
