`
`I, David Clark, 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.
`
`2.
`
`My office is at 141 W. Jackson, Chicago, Illinois.
`
`I have been trading futures for over 10 years. From 1994-1998, I traded for
`3.
`Transmarket Group L.L.C., a private trading and investment company. When I first
`started, I was trading futures on the 2 year treasury notes on the floor at the Chicago
`Board of Trade ("CBOT"). I began using Project A to trade electronically in the
`afternoons shortly after it first carne out sometime in 1998. Project A was the first
`electronic trading system provided by the CBOT.
`
`In 1998, I began trading independently. In the fall of2000, I started trading
`4.
`electronically using TT software and, in particular, TT' s MD Trader product. I continue
`to use TT's MD Trader product to trade electronically today. At the time I decided to
`license TT's software, I was aware of the Project A front-end and software offered by
`Yes Trader. I choose TT and MD Trader because it was far superior to these other front(cid:173)
`ends.
`
`MD Trader was superior because it simplified order entry and sped up the process
`5.
`of trading. By allowing a trader to enter orders with one click at fixed price levels with
`no risk of the prices changing, MD Trader eliminated steps required by the other trading
`systems at the time. This allowed traders to enter orders quicker and with more
`confidence. MD Trader also provided a more efficient graphical representation of the
`market than the other trading systems at the time by displaying the market information
`relative to a fixed range of prices such that the market moved up and down on the screen.
`This allowed a trader to recognize market movement with much less mental effort than
`required by the other systems at the time. This was so because the other systems required
`the trader to focus on numbers and mentally recognize and calculate differences in those
`numbers.
`
`Speed is everything in electronic trading. Anything that allows an electronic
`6.
`trader to act quicker or make decisions faster is invaluable. MD Trader does just that by

`
`
`allowing a trader to move at a faster pace and enter orders quicker than the other systems
`that were available at the time it was first released.
`
`I declare under penalty of perjury that the foregoing is true and correct. Executed on July
`-;;.13t) ' 2004.
