The following communication was sent to the Class B-2 shareholders by David Wescott nominee for Class B-2 director on or after May 7, 2012:

First, I would like to thank the FIA PTG for this endorsement. With all of the issues confronting our industry, many important decisions will be made by CME Group. Running this year has been a little different than in the past. Every aspect of our business seems to find its way into a headline or blog almost daily, from political comments on speculation to margins to tax treatment. In reaching out to our Class B-2 shareholders/ IMM seat holders, I’ve had the opportunity to discuss concerns that trading firms have about our industry. And frankly, I expect this to be an election where every vote counts.

Most of you should have received the Class B-2 proxies by now by mail or electronically, voting ends May 22nd. If you didn’t receive them, we can help you contact the CME to obtain your proxy control number (used for online voting). For help with this, call Michelle Barger at (312) 604 6028.

Thanks for your support,

Subject: CME Board Election - REMINDER

FIA PTG Members:

As we have discussed, participation in the CME Board Election by B-1 and B-2 members has historically been low - please remember to exercise your right to vote. The deadlines for voting are May 22 (online) and May 23 (at the annual meeting).

As you know we created a Working Group who interviewed the 6 candidates and presented their recommendations at last month’s FIA PTG Meeting. Please find a recap of that presentation below:



FIA PTG’s vetting committee spent nearly six hours interviewing the candidates who are campaigning for the B-1 and B-2 positions on the Board of CME Group. To evaluate each candidate’s overall knowledge of the issues and alignment with the interests of PTG, the committee posed 10 questions, in advance, for each candidate to study and discuss with us during our meeting.



The questions covered exchange fees, block trades, settlements, the role of implieds, regulatory reform, datacenters as profit centers, clearing of swaps, CME Group’s competitive position, industry concerns and any conflicts of interest.



The committee reached a unanimous decision that the following candidates would best represent our interests on the Board of CME Group and therefore recommend PTG Members vote for:



Gerard Shannon (B-1 Candidate); and


David Wescott (B-2 Candidate)
