DECLARATION OF MARK A. MENDELSON
`
`I, Mark A. Mendelson, declare that:
`
`I am personally familiar with the facts set forth herein, and, if called as a witness,
`1.
`I could and would testify thereto of my own personal knowledge.
`
`I received a Business Degree from the University of Illinois in 1975. I started my
`2.
`career trading on the floor of the Chicago Board of Trade ("CBOT") in 1981.
`
`I started trading futures electronically in the 1998-99 time frame on Project A, the
`3.
`CBOT' s first effort in the area of electronic trading. I started using TT' s software to
`trade electronically sometime in 2000, shortly after TT launched MD Trader. In January
`of 2001, I left the floor and began trading exclusively electronically.
`
`I first saw MD Trader at a demonstration in around August of 2000. At the time,
`4.
`I was using Project A software to trade electronically at the CBOT. The MD Trader
`product was significantly different than the typical electronic order entry tools in
`existence at the time. When I first saw it, I thought MD Trader looked like a tremendous
`product that offered great advantages over the existing screens. Unlike those existing
`screens, MD Trader presented the trader with an intuitive display of the market
`information such that the trader could see the movement of the market information
`against a fixed range of prices. This improved visualization was significant because it
`reduced the mental calculations need to be performed by the trader when using the
`preexisting screens. MD Trader also allowed for error free one-click order entry because
`a trader was able to enter orders by clicking on cells in alignment with the fixed prices
`and there was no risk of the prices changing as in the preexisting screens.
`
`Soon after first seeing the demonstration of MD Trader, I became a customer of
`5.
`TT and began using MD Trader. When I started using the product, I experienced first(cid:173)
`hand the benefits that this product brought over the preexisting screens. For example, by
`reducing the mental burden on the trader, MD Trader increased the speed in which I
`could react to opportunities. Also, the fast and accurate order entry mechanism provided
`by MD Trader increased the speed in which I could enter an order and reduced errors in
`order entry. In addition, MD Trader has a one-click recentering feature that is very
`valuable because it allows the trader to easily and quickly bring the display of the market
`to the center of the screen and set a point of reference going forward. I had never seen
`any of these features in preexisting electronic trading tools.
`
`Because of the more intuitive trading screen and the improved order entry and
`6.
`management, the MD Trader screen substantially increases the speed in which traders can

`
`react to opportunities and enter orders. Speed of reaction and order entry are critical
`factors determining the success of an electronic trader. Anything that allows a trader to
`increase such speed is invaluable.
`
`Sometime after TT launched MD Trader, I recall that Future Dynamics came out
`7.
`with a trading screen called Crossfire that had similar features to MD Trader. I tried out
`the Future Dynamics product, but thought that TT's product was better.
`
`I declare under penalty of perjury that the foregoing is true and correct. Executed on July
`~.2004.
