`
`I, Brian Gelber, 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 am Chairman of Gelber Group, LLC, located at 141 W. Jackson, 21st Floor,
`2.
`Chicago, IL 60604. Gelber Group has been a Full Clearing Member of the Chicago
`Board ofTrade ("CBOT") and the Chicago Mercantile Exchange ("CME") since 1989.
`Gelber Group is also a Full Clearing Member of OneChicago and NQLX and an
`Exchange Member ofEurex, LIFFE Connect and Matif. Gelber Group accounts for
`approximately 5-10% of the total electronic volume traded on the CBOT and the CME.
`
`I have over 25 years experience in the trading world. I started my career as a
`3.
`broker in 1977 on the T -bond floor of the CBOT. In 1979, I began trading for my own
`account on the floor. From 1979 to 1985, I was one ofthe largest brokers and local
`traders ofT-bond futures at the CBOT. In 1986, I left the floor. Gelber Group first
`started trading interactively by computer in 1998.
`
`In 1999, Gelber Group chose Patsystems as its primary vendor for electronic
`4.
`trading software. This decision was based primarily on cost.
`
`After TT launched MD Trader, TT became Gelber Group's primary vendor. The
`5.
`decision to switch was based primarily on the fact that Gelber Group's traders found TT's
`product, and in particular the MD Trader tool, to be a premium product offering more
`information for those who interactively traded as compared to the competition. Gelber
`Group made this switch despite the fact that TT's software was more expensive than the
`Patsystems software. I recall that some of the reasons why Gelber Group's traders liked
`MD Trader had to do with an improved visual appearance in which it was easy to see
`movements in the market and with other functionality of the tool.
`
`I declare under penalty of peijury that the foregoing is true and correct. Executed on
`August _3_, 2004.
