An incoming BBO ISO shall execute against the CHX Book at prices not to exceed the more restrictive of its limit price or the contra-side displayed best bid or offer. Any unexecuted balance of the BBO ISO shall be immediately cancelled if -1- marked Immediate Or Cancel, as defined under paragraph (d)(4) below, or -2- the incoming BBO ISO sell (buy) order could execute against any resting order(s) priced below (above) the displayed best bid (offer), regardless of the attached order duration modifier(s). If the unexecuted balance of the BBO ISO would not be cancelled as described above, it shall be ranked on the CHX Book, pursuant to Article 20, Rule 8(b), and displayed at its limit price, subject to Article 20, Rule 8(b)(6). A limit order marked BBO ISO may not be marked Do Not Display, as defined under paragraph (c)(2) below. The Matching System, in executing the ISO as soon as the order is received by the Matching System, shall not take any of the actions described in Article 20, Rule 5 to prevent an improper trade-through or any of the actions described in Article 20, Rule 6 to prevent a locked or crossed market; provided, however, that, in executing any initially unexecuted balance of the ISO that is placed in the Matching System, the requirements of Article 20, Rule 5 will be followed. These orders shall be executed on the assumption that the Participant routing the order to the Matching System has already satisfied the quotations of other markets as required by Rule 600(b)(30) and shall be displayed because the Participant routing the order to the Rules of the Chicago Stock Exchange, Inc. Page 17

Matching System has already satisfied the quotations of other markets as required by Article 20, Rule 6(c)(3). A limit order marked BBO ISO shall be deemed to have been received Do Not Route, as defined under paragraph (b)(3)(a), which cannot be overridden by the order sender. (B) "Cancel On Halt": a limit order modifier that requires an order to be automatically cancelled by the Matching System if a trading halt, pause or suspension is declared in that security by the Exchange. All limit orders, except for SNAP AOOs, as defined under paragraph (h)(3), shall be deemed to have been received Cancel On Halt, which cannot be overridden by an order sender. (C) CHX Only : a limit order modifier that requires an order to be ranked and executed on the Exchange pursuant to Article 20, Rule 8, without routing away to another Trading Center and is eligible for the CHX Only Price Sliding Processes, detailed below. An order sender may not opt out of the CHX Only Price Sliding Processes if the order is marked CHX Only. An order sender can enter instructions to have all limit orders default to CHX Only. A limit order marked CHX Only shall be deemed to have been received Do Not Route, as defined under paragraph (b)(3)(a), which cannot be overridden by the order sender. The CHX Only Price Sliding Processes utilized by the Matching System include both Regulation NMS Price Sliding ( NMS Price Sliding ) and Short Sale Price Sliding. All CHX Only orders that are eligible for the CHX Only Price Sliding Processes may be subject to either NMS Price Sliding or Short Sale Price Sliding. CHX Only orders shall also be eligible for Limit Up-Limit Down Price Sliding ( LULD Price Sliding ), pursuant to Article 20, Rule 2A(b)(2). (i) NMS Price Sliding. (a) Initial NMS Price Sliding. A CHX Only order that, at the time of entry, would lock or cross a Protected Quotation of an external market in violation of Rule 610(d) of Regulation NMS; is priced at or through a contra-side Protected Quotation of an external market and is for an Odd Lot; or is priced through a contra-side Protected Quotation of an external market and is marked Do Not Display, as defined under Article 1, Rule 2(c)(2), will be executable at the locking price in the Matching System and, if not marked Do Not Display, will be displayed or displayable by the Matching System at one minimum price variation below the current Rules of the Chicago Stock Exchange, Inc. Page 18

National Best Offer ( NBO ) (for bids) or at one minimum price variation above the current National Best Bid ( NBB ) (for offers) ( Permitted Display Price ). CHX Only orders subject to NMS Price Sliding will retain their original limit prices irrespective of the prices at which such orders are executable or displayed. If the NBB (NBO) is priced below (above) the Lower (Upper) Price Band, an incoming CHX Only sell (buy) order that, at the time of entry, is priced below (above) the Lower (Upper) Price Band, shall be executable and, if not marked Do Not Display, displayed or displayable at the Lower (Upper) Price Band, pursuant to Article 20, Rule 2A(b)(2)(A)(i). (b) Multiple NMS Price Sliding. Following the initial ranking and display of an order subject to NMS Price Sliding, the order will be continuously price slid until the order is executed, cancelled or its original limit price is reached. A CHX Only order subject to NMS Price Sliding will only be price slid to the extent it achieves a more aggressive price, based upon changes to the prevailing National Best Bid and Offer ( NBBO ); provided however that an order may be price slid to a less aggressive price, subject to subparagraphs (3) to (6) below. (1) In the event the NBBO changes such that a CHX Only order subject to NMS Price Sliding could be executable at a higher trading increment (for buy orders) or lower trading increment (for sell orders), without crossing a Protected Quotation of an external market, the order will be executable at the current locking price. If, however, the NBB (NBO) moves to a price below (above) the Lower (Upper) Price Band, the executable price of the CHX Only sell (buy) order shall be price slid to the Lower (Upper) Price Band, pursuant to Article 20, Rule 2A(b)(2)(A)(ii). (2) Re-display. In the event that the NBBO changes such that a CHX Only order subject to NMS Price Sliding could be redisplayed or re-displayable at a higher trading increment (for buy orders) or lower trading increment (for sell orders), without locking or crossing a Protected Quotation of an external market, the order will be re-displayed at the current Permitted Display Price. If, however, the NBB (NBO) moves to a price below (above) the Lower (Upper) Price Band, the resting CHX Only order shall be redisplayed at the Lower (Upper) Price Band, pursuant to Article 20, Rule 2A(b)(2)(A)(ii). Rules of the Chicago Stock Exchange, Inc. Page 19

(3) External Protected Quotation Locks Displayed or Displayable Price. In the event that the Protected Quotation of an external market locks the displayed or displayable price of a resting price slid order and the Matching System receives a marketable contra-side order, the Matching System will price slide the executable price of the resting price slid order to the displayed or displayable price. Such event will not result in a change in priority for the resting price slid order at its displayed price. (4) External Protected Quotation Crosses Displayed Price. In the event that the Protected Quotation of an external market crosses the displayed price of a resting price slid order, the Matching System shall price slide and display the resting order based on the first uncrossed NBBO calculated pursuant to paragraph.01(d) of Article 20, Rule 5, if necessary. In the event the first uncrossed NBBO is locked, the resting order shall be subject to subparagraph (3). In the event the first uncrossed NBBO is not locked, the resting order shall be subject to subparagraphs (1) and (2). (5) CHX Only orders marked Do Not Display. In the event that a Protected Offer (Bid) of an external market crosses a resting CHX Only bid (offer) marked Do Not Display, the resting bid (offer) marked Do Not Display shall be price slid to lock the Protected Offer (Bid) of the external market. (6) CHX Only orders marked Reserve Size. A resting CHX Only order marked Reserve Size shall be price slid to a less aggressive price if a refreshed display of the order would lock or cross a Protected Quotation of an external market and shall receive execution priority pursuant to Article 20, Rule 8(b)(4). (ii) Short Sale Price Sliding. A limit order marked Sell Short, as defined under Article 1, Rule 2(b)(3)(D), must comply with the requirements of Article 20, Rule 8(d)(4). If the Sell Short order is marked CHX Only, the order shall be price slid as follows: (a) Initial Short Sale Price Sliding. A CHX Only Sell Short order that, at the time of entry, could not be executed or displayed in compliance with Rule 201 of Regulation SHO will be repriced (and displayed, if applicable) by the Matching System at one minimum price variation above the current NBB ( Permitted Price ). CHX Only orders Rules of the Chicago Stock Exchange, Inc. Page 20

subject to Short Sale Price Sliding will retain their original limit prices, notwithstanding price sliding. If the Permitted Price is priced below the Lower Price Band, an incoming CHX Only Sell Short order that, at the time of entry, is priced below the Lower Price Band, shall be repriced (and displayed, if applicable) at the Lower Price Band, pursuant to Article 20, Rule 2A(b)(2)(A)(i). (b) Multiple Short Sale Price Sliding. To reflect declines in the NBB, the Matching System will continue to reprice (and re-display, if applicable) a CHX Only Sell Short order to the greater of the Permitted Price or the Lower Price Band, until the order is executed, cancelled or its original limit price is reached, pursuant to Article 20, Rule 2A(b)(2)(A)(ii). To reflect increases in the NBB, the Matching System will continue to reprice an undisplayed CHX Only Sell Short order to the greater of the Permitted Price or the Lower Price Band, until the order is executed, cancelled or its original limit price is reached, pursuant to Article 20, Rule 2A(b)(2)(A)(ii). (c) Priority over NMS Price Sliding. When a short sale price test restriction under Rule 201 of Regulation SHO is in effect for a particular security, Short Sale Price Sliding will take priority over NMS Price Sliding, with respect to CHX Only sell short orders in that security that are subject to Short Sale Price Sliding. (d) Exemptions. (1) As detailed under Article 20, Rule 8(d)(4), when a short sale price test restriction under Rule 201 of Regulation SHO is in effect, the Matching System may execute a CHX Only Sell Short order at a price below the Permitted Price if, at the time of initial display of the CHX Only Sell Short order, the order was at a price above the then current NBB. Notwithstanding this exemption, a CHX Only Sell Short order may never execute (or be displayed, if applicable) at a price below the Lower Price Band. (2) CHX Only orders marked Short Exempt shall not be subject to Short Sale Price Sliding. (iii) Lock-Only Price Sliding. An order sender may enter an instruction to only use the CHX Only Price Sliding Processes if the display of the CHX Only order at the time of order entry would lock the NBBO. If such an instruction is given and the display of an order would cross the NBBO at the time of entry, the order will be rejected from the Matching System. Rules of the Chicago Stock Exchange, Inc. Page 21

(iv) Original Time Priority Retained. CHX Only orders subject to the Price Sliding Processes will retain their time priority versus other orders based upon the time those orders were initially received by the Matching System; provided, however, that the displayed portion of a Reserve Size CHX Only order that is refreshed shall have time priority based on the time the displayed order was refreshed. (D) Post Only : a limit order modifier that requires an order to be posted on the Exchange and not routed away to another trading center. A limit order marked Post Only shall be deemed to have been received Do Not Route, as defined under paragraph (b)(3)(a), which cannot be overridden by the order sender. A Post Only order will be immediately cancelled under the following circumstances: or (i) The Post Only order would remove liquidity from the CHX book; (ii) At the time of order entry, the Post Only order would lock or cross a Protected Quotation of an external market; provided, however, that if the Post Only order is marked CHX Only and is eligible for the CHX Only Price Sliding Processes, pursuant to Article 1, Rule 2(b)(1)(C), the Post Only order that would lock or cross a Protected Quotation of an external market shall be subject to the CHX Only Price Sliding Processes or Limit Up-Limit Down Price Sliding, pursuant to Article 20, Rule 2A(b), whichever is applicable, and shall not be immediately cancelled. (E) "Price-Penetrating ISO": a limit order modifier that marks an order as required by SEC Rule 600(b)(30) that is to be executed at or better than its limit price as soon as the order is received by the Matching System, with any unexecuted balance of the order to be immediately cancelled. Orders marked as Price- Penetrating ISO shall be executed against any eligible orders in the Matching System (including any Reserve Size or undisplayed orders) through multiple price points. The Matching System, in executing these orders, shall not take any of the actions described in Rule 5 to prevent an improper trade-through. A limit order marked Price-Penetrating ISO shall be deemed to have been received Immediate Or Cancel, as defined under paragraph (d)(3), which cannot be overridden by the order sender. (2) Cross Orders Only. The following order execution modifiers may be attributed to cross orders only: Rules of the Chicago Stock Exchange, Inc. Page 22

(A) "Benchmark": a cross order modifier, submitted by an Institutional Broker, to buy and sell the same security at a specific price, which meets the requirements of Rule 611(b)(7). A Benchmark order may execute at any price, without regard to the protected National Best Bid and Offer ( NBBO ) and may represent interest of one or more Participants of the Exchange. A Benchmark order may only be executed in an increment permitted by Article 20, Rule 4(a)(7)(b). (B) (C) Reserved Reserved (D) "Midpoint Cross": a cross order modifier with an instruction to execute it at the midpoint between the NBBO. If the NBBO is locked at the time a Midpoint Cross is received, the Midpoint Cross will execute at the locked NBBO. If the NBBO is crossed at the time a Midpoint Cross is received, the Midpoint Cross will be automatically cancelled. A Midpoint Cross order may only be executed in an increment permitted by Article 20, Rule 4(a)(7)(b). (E) "Qualified Contingent Trade": a cross order modifier that is part of a transaction consisting of two or more component orders, executed as agent or principal, where: (i) at least one component order is in an NMS stock; (ii) all components are effected with a product or price contingency that either has been agreed to by the respective counterparties or arranged for by a broker-dealer as principal or agent; (iii) the execution of one component is contingent upon the execution of all other components at or near the same time; (iv) the specific relationship between the component orders (e.g., the spread between the prices of the component orders) is determined at the time the contingent order is placed; (v) the component orders bear a derivative relationship to one another, represent different classes of shares of the same issuer, or involve the securities of participants in mergers or with intentions to merge that have been announced or since cancelled; and (vi) the Exempted NMS Stock Transaction is fully hedged (without regard to any prior existing position) as a result of the other component of the contingent trade. Rules of the Chicago Stock Exchange, Inc. Page 23

For purposes of this definition, (i) "NMS stock" means any security or class of securities, other than an option, for which transaction reports are collected, processed, and made available pursuant to an effective transaction reporting plan; and (ii) "Exempted NMS Stock Transaction" means any trade-through caused by the execution of an order involving one or more NMS stocks that are components of a Qualified Contingent Trade. (3) Applicable to Multiple Order Types (A) "Do Not Route": a limit or market order modifier that requires an order to only be executed or ranked within the Exchange's Matching System and not be routed to another market. (B) "Intermarket Sweep" or "ISO": a limit or cross order modifier that marks an order as required by SEC Rule 600(b)(30) that is to be executed against any orders at the Exchange's BBO (including any Reserve Size or undisplayed orders at that price) as soon as the order is received by the Matching System, with any unexecuted balance of the order to be immediately cancelled. The Matching System, in executing the ISO, shall not take any of the actions described in Article 20, Rule 5 to prevent an improper trade-through. A limit order marked ISO that is not marked BBO ISO, as defined under paragraph (b)(1)(a), shall be deemed to have been received Price-Penetrating ISO, as defined under paragraph (b)(1)(e), which cannot be overridden by the order sender. (C) "Not Held": an instruction specified by the customer, which permits an Exchange Participant to use her judgment in determining the price of execution and/or the time to execute the order. This instruction may only be applied to orders sent to an Exchange Participant and any order received by the Matching System marked Not Held shall be rejected. (D) "Sell Short": marks any order to sell a security "short" under Rule 200(g) of Regulation SHO. (E) Short Exempt : marks any order to sell a security that is exempt from the short sale price test restriction under Rule 201 of Regulation SHO. (F) Match Trade Prevention ( MTP ) Modifier (i) Enabling/Disabling MTP. The MTP modifier shall only be available for an order that originated from a Trading Account, as defined under Article 1, Rule 1(ll), that has been assigned to an MTP Trading Group, as defined under Article 1, Rule 1(mm). An order that originated from a Trading Account that is not part of an MTP Trading Group shall not be subject to MTP and any attached MTP modifiers shall be ignored. Any Exchange-approved changes to the applicability of Rules of the Chicago Stock Exchange, Inc. Page 24

MTP to a Trading Account shall be effective no earlier than the trading day following the request. (ii) Triggering MTP. An MTP modifier is comprised of a compulsory MTP Action, listed under subparagraph (iii), and an optional MTP sublevel designation. The MTP modifier on the incoming order shall control the interaction between the contra-side orders. An incoming limit or market order marked by an MTP modifier without an MTP sublevel designation will be prevented from executing against a resting opposite side order from the same MTP Trading Group. If the incoming order is marked by an MTP modifier with an MTP sublevel designation, the order will only be prevented from executing against a resting opposite side order from the same MTP Trading Group if the resting order is marked by the same MTP sublevel designation. MTP shall only be applicable to marketable contra-side orders that are both principal orders or are both agency orders. (iii) MTP Actions. An MTP Trading Group must be assigned a default MTP Action. The following MTP Actions may be applied to any incoming limit or market orders at the MTP Trading Group level as a default or at the individual order level ad hoc: (a) MTP Cancel Incoming ( N ): An incoming limit or market order marked N will not execute against opposite side resting interest originating from the same MTP Trading Group or MTP sublevel, if applicable. Only the incoming order will be cancelled pursuant to MTP. (b) MTP Cancel Resting ( O ): An incoming limit or market order marked O will not execute against opposite side resting interest originating from the same MTP Trading Group or MTP sublevel, if applicable. Only the resting order will be cancelled pursuant to MTP. (c) MTP Cancel Both ( B ): An incoming limit or market order marked B will not execute against opposite side resting interest originating from the same MTP Trading Group or MTP sublevel, if applicable. The entire size of both orders will be cancelled pursuant to MTP. (iv) MTP Inactivate ( I ): An incoming limit or market order marked I will inactivate the default MTP Action for the incoming order. I may only be applied at the order level ad hoc. An incoming order marked I may be marked by an optional MTP sublevel designation. (v) The MTP modifier is not compatible with the Fill Or Kill modifier, as defined under paragraph (d)(2). Any limit or market order marked MTP and Fill Or Kill shall be rejected by the Matching System. Rules of the Chicago Stock Exchange, Inc. Page 25
