Futures, and CBOT® Dow JonesTM US Real Estate Index Futures. Hereafter in this regulation, DJIA
Index futures, mini-sized Dow ($5 Multiplier) futures, and DJIA Index ($25 Multiplier) futures and CBOT®
Dow JonesTM US Real Estate Index futures shall be referenced as “DJIA futures”. Daily price limits and
trading halts in DJIA futures shall be coordinated with trading halts in the underlying stocks listed for trading
in the primary securities market.

For purposes of this regulation, the primary contract expiration month for each of the above
mentioned DJIA futures contracts shall be defined as the futures contract that trades in the lead month
configuration. The Executive Committee or its designee shall have the responsibility of determining whether
the primary contract expiration month is limit bid or offered.

For the first day of trading in a newly listed contract expiration month, there will be an implied
previous business day’s settlement price, created by the Exchange for the sole purpose of establishing price
limits. The implied settlement price will be created by extrapolating the annualized percentage carry
between the two contract months immediately prior to the newly listed contract.

Price Limits: For cach calendar quarter, there shall be three successive price limits: Level 1, Level
2, and Level 3. The limit thresholds that define Levels 1, 2, and 3 shall be calculated at the beginning of the
pertinent calendar quarter, using the average daily closing value of the DJIA for the calendar month prior to
the beginning of such calendar quarter. The Level | limit threshold shall equal 10% of such average daily
closing value, the Level 2 limit threshold shall equal 20% of such average daily closing value, and the Level
3 limit threshold shall equal 30% of such average daily closing value. Each limit threshold shall be rounded
to the nearest fifty DJIA index points.

These three limit thresholds, so computed, shall remain in effect throughout the pertinent calendar quarter,
until the next calculation. These limit thresholds shall be used to calculate price limits for each trading
session within the pertinent calendar quarter, as follows:

Level | shail equal the settlement price of the preceding regular trading session minus the Level | limit
threshold.

Level 2 shall equal the settlement price of the preceding regular trading session minus the Level 2 limit
threshold.

Level 3 shall equal the settlement price of the preceding regular trading session minus the Level 3 limit
threshold.

Price Limits During Regular Trading Hours: The following price limits and trading halts shall
apply to open auction and electronic trading, in the primary contract expiration month only, during the
Exchange’s regular trading hours. For purposes of this regulation, “regular trading hours” are defined for all
DJIA futures to begin with the time of the open for open auction trading in DJIA futures, and to end with the
later of the time of the close of open auction trading, or the conclusion of any daytime electronic trading
session that is part of the same trading day.

(a) Level |:

Except as provided below, the Level | price limit shall be in effect until a trading halt has been
declared in the primary securities market, trading in the primary securities market has resumed, and fifty
percent (50%) of the stocks underlying the DJIA (selected according to capitalization weights) have
reopened. The Level 2 price limit shall apply for all DJIA futures to such reopening.
