(a) The following transactions may be executed outside of the Exchange's central markets, in
accordance with the requirements of this Regulation.
(i) Exchanges of futures for, or in connection with, cash commodities (“Exchange for
Physical Transactions” or “EFPs”). EFPs may be executed in all CBOT futures
contracts.
(ii) Exchanges of futures for, or in connection with, swap transactions (“Exchange for

Swap Transactions” or “EFSs”). EFSs may be executed only in U.S. Treasury
Bond futures; Long Term, Medium Term. and Short Term U.S. Treasury Note

Futures. The OTC component of an EFR must comply with any applicable

(iv) Options on futures are not a permissible component of an EFP, EFS or EFR.

For purposes of this Regulation, all EFPs, EFSs and EFRs shall be referred to as Exchanges of Futures
for Related Positions.

(b) The Related Position (cash, swap, or OTC derivative) must involve the commodity
underlying the futures contract, or must be a derivative, by-product or related product of such
commodity that has a reasonable degree of price correlation to the commodity underlying
the futures contract.

(c) An Exchange of Futures for a Related Position consists of two discrete, but related
simultaneous transactions. One party must be the buyer of (or have the long market
exposure associated with) the Related Position and the seller of the corresponding futures,
and the other party must be the seller of (or have the short market exposure associated with)
the Related Position and the buyer of the corresponding futures. However, a member firm
may facilitate, as principal, the Related Position on behalf of a customer, provided that the
member firm can demonstrate that the Related Position was passed through to the customer
that received the futures position as part of the Exchange of Futures for Related Position
transaction.

(d) The accounts involved on each side of an Exchange of Futures for a Related Position: (a)
must have different beneficial ownership; or (b) must be under separate control; or (c) must

involve separate legal entities.

The quantity covered by the Related Position must be approximately equivalent to the
quantity covered by the futures contracts.

Exchanges of Futures for Related Positions may be entered into in accordance with the
applicable trading increments set forth in the rules governing such futures contracts, at such
prices as are mutually agreed upon by the two parties to the transaction.

Clearing firms on opposite sides of an Exchange of Futures for a Related Position must
subsequently approve the terms of the transaction, including the clearing firm (division),
price, quantity, commodity, contract month and date prior to submitting the transaction to the
Clearing Services Provider. All Exchanges of Futures for Related Positions must be
submitted to the Clearing Services Provider by a clearing firm acting on its own behalf or for
the beneficial account of a customer who is a party to the transaction.

Each Exchange of Futures for a Related Position shall be designated as such, and cleared
through the Exchange's Clearing Services Provider as if it were a transaction executed in the
Exchange’s central markets. The transaction shall be submitted to the Clearing Services
Provider within the time period and in the manner specified by the Clearing Services
Provider.

The time of execution of an Exchange of Futures for a Related Position must be recorded on
the futures order ticket, and on the record submitted to the Exchange’s Clearing Services
Provider.

Parties to any Exchange of Futures for a Related Position must maintain all documents
relevant to the futures and the cash, swap, or OTC transactions, including all documents
customarily generated in accordance with cash or other relevant market practices and any
documents reflecting payment and transfer of title, and must provide such documents to the
Exchange upon its request.

or a member firm that carries for another person, aggregate positions in excess of those specified in the

chart below,

shall be subject to the following provisions:

- Such person shall provide, in a timely manner upon request by the Exchange, information regarding
the nature of the position, trading strategy, and hedging information if applicable.

- Such person shall be deemed to have consented, when so ordered by the Exchange acting in its
discretion, not to further increase the positions which exceed the levels specified in the chart below.

- Such positions must be initiated and liquidated in an orderly manner.

For purposes of this regulation, all positions in accounts for which a person, by power of attorney or
otherwise, directly or indirectly controls trading shall be included with the positions held by such person.

an expressed or implied agreement or understanding, the same as if the positions were held by a single
