Re: Security Futures Products Rule Submission and Rule Certification

Dear Ms. Donovan:

On behalf of my client, OneChicago, LLC, and pursuant to sectionSc(c)(1) of the
Commodity Exchange Act, as amended (the “‘Act”), and section 41.24 of the regulations
promulgated by the Commission under the Act, submitted herewith is a rule amendment
to the OneChicago, LLC (“OneChicago”) Rules 144, 404, 406 and 416 relating to the
OneChicago System, Acceptable Orders, Execution of Orders by the OneChicago System
and Exchange of Futures for Physical (“EFP”) transactions, respectively, and conforming
non-substantive amendments. These changes are being made in conjunction with the
initiation of the OneChicago Block & EFP Trading System (“OneChicago BETS”), an
electronic system which will permit authorized traders to trade and report block and
Block Roll trades and provide a matching and reporting system for EFP transactions.
OneChicago Rules 416 and 417 dealing with EFPs and block trades will apply to
OneChicago BETS. Thus, each party to a block trade or Block Roll on OneChicago
BETS must qualify as an “eligible contract participant” as such term is defined in Section
1a(12) of the Act.

The rule amendments will be effective on July 20, 2007.

There are no opposing views that are not incorporated into this rule amendment.
This rule change has also been filed with the Securities and Exchange Commission.


Off-Exchange Transactions
416. Exchange of Future for Physical

(a) No Change

(b) No Change

(c) No Change

(d) No Change

(e) No Change

(f) An Exchange Member or Access Person authorized by a Clearing

Member, whose bid or offer for an Exchange of Future for Physical is

matched _to a counterparty by OneChicago BETS, is obligated to
complete the transaction unless some other provision of these Rules

provides otherwise.



On behalf of OneChicago, I hereby certify that that the amendment to the
Reporting Procedures has been filed with Securities and Exchange Commission and
complies with the Act and regulations promulgated thereunder.

Regards,
