The weekly Regulatory Bulletin is delivered to all effective members to satisfy this requirement. Copyright © 2004 Chicago Board Options Exchange, Incorporated Regulatory Circulars Regulatory Circular RG05-71 To: The Membership From: Division of Regulatory Services Date: August 31, 2005 Subject: Broad-Based Index Portfolio Margin Program for Certain Customers Exchange Contacts: James Adams (312) 786-7718 KEY POINTS • On July 14, 2005, the Securities and Exchange Commission (the “SEC” or “Commission”) approved rule filings by the Chicago Board Options Exchange (the “CBOE” or “Exchange”) and New York Stock Exchange that permit member organizations to compute a margin requirement for broad-based index options and related exchange traded funds of certain customers using a portfolio (risk-based) methodology. • With the exception of a broker-dealer customer or member of a national futures exchange,1 a customer must have or establish, and maintain, equity of not less than five million dollars across one or more accounts with the member organization in order to open a portfolio margin and/or a cross-margin account (see 4th bullet below). Member organizations may combine all accounts (including futures accounts) carried for the same customer in identical ownership name for the purpose of meeting the minimum equity requirement. • Only the theoretical option prices supplied by The Options Clearing Corporation (“OCC”) may be used by member organizations for computing gains and losses on option positions used to produce the portfolio margin requirement. The customer portfolio margin program utilizes the same framework now used by member organizations to compute risk-based capital charges (haircuts) and the data are obtained from the OCC in the same manner. • For member organizations that are also futures commission merchants (“FCM”),2 the approved rules also provide for a separate customer cross-margin account in which broad-based index futures and options on such futures can be combined with corresponding securities index options and exchange traded funds, and for a margin requirement to be computed by applying the portfolio margin methodology. 1 The five million dollar minimum account equity requirement does not apply to cross-margining of a member of a national futures exchange provided the member is hedging its index futures / options positions with securities index options. 2 In addition to being a FCM, member organizations must be a clearing member of a futures clearing organization or have an affiliate that is a clearing member of a futures clearing organization. If a member organization has a customer omnibus relationship with another broker-dealer, that broker-dealer must meet the foregoing requirements. Regulatory Circulars continued Regulatory Circular RG05-71 continued • However, a cross-margin account must be carried as a securities account, and until such time as relief is granted by the Commodity Futures Trading Commission (“CFTC”), member organizations must comply with the customer protection requirements of both the SEC and CFTC in respect of futures and options on futures carried in a customer cross-margin account. • Clearing members that wish to take advantage of customer portfolio margin and/or cross-margin at the clearing house level should contact The Options Clearing Corporation. DISCUSSION The broad-based index portfolio margin program for certain customers is codified under new Rule 12.4 – Portfolio Margin and Cross-Margin for Index Options. The rule specifies which instruments are eligible for the portfolio margin and cross-margin accounts, market ranges for computing the margin requirement, which persons are eligible to participate, requirements for opening a portfolio margin or cross-margin account, the manner in which a margin requirement is to be computed and actions required in the event of a deficiency in the required margin or the required minimum account equity. As noted above, a customer must have and maintain a minimum account equity in order to be eligible for portfolio margining. On or before the date of an initial transaction in a portfolio margin account, a customer must be provided with a special written disclosure statement describing the nature and risks of portfolio margining and cross-margining, and the customer must sign and return an acknowledgement form. If a cross-margin account is opened, there is a separate acknowledgement form that must also be returned. Generally, the rules prohibit an underlying instrument (i.e., an exchange traded fund) from being carried in a portfolio margin or cross-margin account, or futures / options on futures from being carried in a cross-margin account, unless there is an offsetting position. The portfolio margin requirement is both an initial and maintenance margin requirement. Guarantees by any other account for purposes of margin requirements are not permitted. There will be a minimum margin requirement of $.375 for each listed option contract and related instrument multiplied by the contract or instrument’s multiplier, not to exceed the market value in the case of long positions in listed options and options on futures contracts. If at any time, the equity in a portfolio margin or cross-margin account is less than the margin required, the member organization must obtain sufficient margin to cover the deficit within one business day (T+1). Member organizations are required under new Exchange Rule 13.5 – Customer Portfolio Margin Accounts, to limit gross customer portfolio margin requirements, including margin required in cross-margin accounts, to not more than 10 times net capital. Member organizations are also required under new Exchange Rule 15.8A – Risk Analysis of Portfolio Margin Accounts, to establish and maintain written procedures for assessing and monitoring the potential risk to the member organization’s capital in connection with its customer portfolio margin and cross-margin accounts. A more detailed summary of the portfolio margin and cross-margin rules is available. A copy may be requested from, and any questions concerning portfolio margin and cross-margin accounts should be directed to, James Adams at (312) 786–7718. The summary may also be found at the following web site: www.cboe.com/Institutional/Margin.aspx#changes. RB2 September 7, 2005, Volume RB16, Number 36 Rule Changes, Interpretations and Policies APPROVED RULE CHANGE(S) The Securities and Exchange Commission (“SEC”) has approved the following change(s) to Exchange Rules pursuant to Section 19(b) of the Securities Exchange Act of 1934, as amended (“the Act”).

Rule 4.11 - Position Limits Rule 4.11. Except with the prior permission of the President or his designee, to be confirmed in writing, no member shall make, for any account in which it has an interest or for the account of any customer, an opening transaction on any exchange if the member has reason to believe that as a result of such transaction the member or its customer would, acting alone or in concert with others, directly or indirectly, (a) control an aggregate position in an option contract dealt in on the Exchange in excess of 13,500 or 22,500 or 31,500 or 60,000 or 75,000 option contracts (whether long or short), except that for a pilot program period of 6 months (“Rule 4.11 Pilot Program Period”) from August 24, 2005 through February 23, 2006, the position limits shall be 25,000 or 50,000 or 75,000 or 200,000 or 250,000 option contracts (whether long or short), of the put type and the call type on the same side of the market respecting the same underlying security, combining for purposes of this position limit long positions in put options with short positions in call options, and short positions in put options with long positions in call options, or such other number of option contracts as may be fixed from time to time by the Exchange as the position limit for one or more classes or series of options, or (b) exceed the applicable position limit fixed from time to time by another exchange for an option contract not dealt in on the Exchange, when the member is not a member of the other exchange on which the transaction was effected. In addition, should a member have reason to believe that a position in any account in which it has an interest or for the account of any customer is in excess of the applicable limit, such member shall promptly take the action necessary to bring the position into compliance. Reasonable notice shall be given of each new position limit fixed by the Exchange, by publicly posting notice thereof. Limits shall be determined in the manner described in Interpretations .02 and .04 below. September 7, 2005, Volume RB16, Number 356 RB3 Rule Changes, Interpretations and Policies continued PROPOSED RULE CHANGE(S) Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934, as amended (“the Act”), and Rule 19b-4 thereunder, the Exchange has filed the following proposed rule change(s) with the Securities and Exchange Commission (“SEC”). Copies of the rule change filing(s) are available at www.cboe.com/legal/submittedsecfilings.aspx. Members may submit written comments to the Legal Division. The effective date of a proposed rule change will be the date of approval by the SEC, unless otherwise noted. SR-CBOE-2005-65 Automated RFQ Auction Mechanism On August 24, 2005, the Exchange filed Rule Change File No. SR-CBOE-2005-65, which filing proposes to amend CBOE Rule 6.53C to provide for an automated RFQ auction mechanism for incoming eligible complex orders and to make certain other revisions to the existing complex order book rule text. Any questions regarding the rule change may be directed to Angelo Evangelou, Legal Division, at 312-786-7464. The text of the proposed rule amendments is set forth below. Proposed new language is underlined. Proposed deleted language is [bracketed and stricken-through]. Rule 6.53C. Complex Orders on the Hybrid System RULE 6.53C. (a) – (b) No change. (c) Complex Order Book (i) No change. [(ii) Priority of Complex Orders in the COB: Orders from public customers have priority over orders from non-public customers. Multiple public customer complex orders at the same price are accorded priority based on time.] [(iii)](ii) Execution of Complex Orders in the COB: Complex orders resting in the COB may be executed without consideration to prices of the same complex orders that might be available on other exchanges. Complex orders resting in the COB may trade in the following way: (1) Orders and Quotes in the [Electronic Book (“E]Book[”)]: A complex order in the COB will automatically execute against individual orders or quotes residing in the [E]Book provided the complex order can be executed in full (or in a permissible ratio) by the orders and quotes in the [E]Book. (2) Orders in COB: Complex orders in the COB that are marketable against each other will automatically execute. The allocation of a complex order within the COB shall be pursuant to the rules of trading priority otherwise applicable to incoming electronic orders in the individual component legs. (3) Market participants, as defined in CBOE Rule 6.45A or 6.45B, as applicable, may submit orders or quotes to trade against orders in the COB. The allocation of complex orders among market participants shall be done pursuant to CBOE Rule 6.45A(c) or 6.45B(c), as applicable. RB4 September 7, 2005, Volume RB16, Number 36 Rule Changes, Interpretations and Policies continued SR-CBOE-2005-65 continued [(iv)](iii) Complex orders in the COB may be designated as day orders or good-til-cancelled orders. Only those complex orders with no more than four legs and having a ratio of one-tothree or lower, as determined by the appropriate Exchange committee, are eligible for placement into the COB. (d) Process for Complex Order RFQ Auction: Prior to routing to the COB, eligible incoming complex orders will be subject to an automated request for quotes process. (i) For purposes of paragraph (d): (A) “COA” is the automated complex order request for quotes (“RFQ”) auction process. (B) A “COA-eligible order” means an incoming complex order that, as determined by the appropriate Exchange committee on a class-byclass basis, is eligible for a COA considering the order’s marketability (defined as a number of ticks away from the current market), size and complex order type, as defined in paragraph (a) above. All pronouncements regarding COA eligibility will be announced to the membership via Regulatory Circular. Complex orders processed through a COA may be executed without consideration to prices of the same complex orders that might be available on other exchanges. (C) The “Response Time Interval” means the period of time during which responses to the RFQ may be entered. (ii) Initiation of a COA: On receipt of a COA-eligible order, the Exchange will send an RFQ message to market participants who have subscribed to receive such RFQ messages (“RFQ Recipients”). The RFQ message will identify the component series, the size of the COA-eligible order and any contingencies, if applicable. (iii) Bidding and Offering in Response to RFQs: RFQ Recipients may submit responses to the RFQ message (“RFQ Responses”) during the Response Time Interval. (A) RFQ Response sizes will be capped at the size of the COAeligible order for allocation purposes. (B) The appropriate Exchange committee will determine the length of the Response Time Interval on a class-by-class basis; provided, however, that the duration shall not exceed three (3) seconds. All pronouncements regarding the Response Time Interval will be announced to the membership via Regulatory Circular. (iv) Processing of COA-Eligible Orders: At the expiration of the Response Time Interval, COA-eligible orders will be allocated in accordance with subparagraph (v) below or routed in accordance with subparagraph (vi) below. (v) Execution of COA-Eligible Orders: COA-eligible orders may be executed without consideration to prices of the same complex orders that might be available on other exchanges. COA-eligible orders may trade in the following way: September 7, 2005, Volume RB16, Number 356 RB5 Rule Changes, Interpretations and Policies continued SR-CBOE-2005-65 continued (1) The individual orders and quotes residing in the Book shall have first priority to trade against a COA-eligible order provided the COA-eligible order can be executed in full (or in a permissible ratio) by the orders and quotes in the Book. The allocation of a COA-eligible order against the Book shall be consistent with the UMA allocation described in Exchange Rules 6.45A or 6.45B, as applicable. (2) Public customer complex orders resting in the COB and public customer complex orders that are received during the Response Time Interval shall, collectively, have second priority to trade against a COA-eligible order. The allocation of a COA-eligible order against the public customer complex orders resting in the COB shall be according to time priority. (3) Non-public customer orders resting in the COB, non-public customer orders that are received during the Response Time Interval and RFQ responses shall, collectively, have third priority. The allocation of a COAeligible order against these opposing orders shall be consistent with the CUMA allocation described in Exchange Rules 6.45A or 6.45B, as applicable. (vi) Routing of COA-Eligible Orders: If a COA-eligible order cannot be filled in whole or in a permissible ratio, the order will route to the COB. (vii) Firm Quote Requirement for COA-Eligible Orders: The firm quote requirements of Exchange Rule 8.51 and SEC Rule 11Ac1-1 shall apply only to quotes as they may exist at the end of the Response Time Interval. In addition, RFQ Responses shall be firm only with respect to the COA-eligible order for which it is submitted, provided that RFQ Responses that exceed the size of a COA-eligible order are also eligible to trade with other incoming COA-eligible orders that are received during the Response Time Interval. Any RFQ Responses not accepted in whole or in a permissible ratio will expire at the end of the Response Time Interval. (viii) Handling of Related Complex Orders: Incoming complex orders that are received prior to the expiration of the Request Response Interval for a COAeligible order (the “original COA”) will impact the original COA as follows: (1) Incoming complex orders that are received prior to the expiration of the Request Response Interval for the original COA that are on the opposite side of the market and are marketable against the starting price of the original COA-eligible order will cause the original COA to end. The operation of the original COA will not change other than the early termination thereof. For purposes of this Rule, the “starting price,” shall mean the better of the original COA-eligible order’s limit price or the best price, on a net debit or credit basis, that existed in the Book or COB at the beginning of the Request Response Interval. (2) Incoming COA-eligible orders that are received prior to the expiration of the Request Response Interval for the original COA that are on the same side of the market and at the same price or worse than the original COA-eligible order will join the original COA. The operation of the original COA will not change. The priority of the original COA-eligible order and incoming COA-eligible order(s) shall be according to time priority.

The following terms shall have the meaning specified in the Rule solely for the purpose of this Section E under Chapter VI: (1)-(8) No change. (9) “Firm Customer Quote Size” with respect to a P/A Order means the size of the disseminated quotation of the Participant receiving the P/A Order. [the lesser of (a) the number of option contracts that the Participant Exchange sending a P/A Order guarantees it will automatically execute at its disseminated quotation in a series of an Eligible Option Class for Customer orders entered directly for execution in that market; or (b) the number of option contracts that the Participant Exchange receiving a P/A Order guarantees it will automatically execute at its disseminated quotation in a series of an Eligible Option Class for Customer orders entered directly for execution in that market. The Firm Customer Quote Size will be at least 10 contracts for each series of an Eligible Option Class unless the receiving Participant Exchange is disseminating a quotation of less than 10 contracts, in which case this number may equal such quotation size.] (10)-(21) No change. ***** Rule 6.81 — Operation of the Linkage Rule 6.81. By subscribing to the Plan, the Exchange has agreed to comply with, and enforce compliance by its members with, the Plan. In this regard, the following shall apply: (a) No change. (b) P/A Orders September 7, 2005, Volume RB16, Number 356 RB7 Rule Changes, Interpretations and Policies continued SR-CBOE-2005-68 continued (1) Sending of P/A Orders for Sizes No Larger than the Firm Customer Quote Size. A Market-Maker may send through the Linkage a P/A Order that is equal to or less than the size of [for execution in the automatic execution system of a Participant Exchange if the size of such P/A Order is no larger than] the Firm Customer Quote Size for automatic execution, if available. [Except as provided in subparagraph (b)(2)(ii) below, a Market-Maker may not break up an order of a Customer that is larger than the Firm Customer Quote Size into multiple P/A Orders, one or more of which is equal to or smaller than the Firm Customer Quote Size, so that such orders could be represented as multiple P/A Orders through the Linkage.] (2) Sending of P/A Orders [for Sizes] Larger than the Firm Customer Quote Size. If the size of a P/A Order is larger than the Firm Customer Quote Size, a Market-Maker may send through the Linkage such P/A Order in one of two ways: (i) The Market-Maker may send a P/A Order representing the entire Customer order. If a receiving Participant Exchange’s disseminated quotation is equal to or better than the Reference Price when the P/A Order arrives at that market, that exchange will execute the P/A Order at its disseminated quotation for at least the Firm Customer Quote Size (an automatic execution is not required if the P/A Order is larger than the Firm Customer Quote Size). Within 15 seconds of receipt of such order, the receiving Participant Exchange will inform the Market-Maker of the amount of the order executed and the amount, if any, that was canceled. (ii) Alternatively, the Market-Maker may send an initial P/A Order for the Firm Customer Quote Size pursuant to subparagraph (b)(1) above. If one or more of the Participant Exchanges that executed the P/A Order continues to disseminate the same quotation at the NBBO [15 seconds] after reporting the execution of the initial P/A Order, the Market-Maker may send an additional P/A Order to such Participant Exchanges. If sent, such additional P/A Order must be for at least the lesser of: (i) the size of the disseminated quotation; (ii) 100 contracts; or (iii) the entire remainder of the Customer order. If the sending Participant Exchange initially sent P/A Orders to more than one Participant Exchange for up to the Firm Customer Quote Size, the sending Participant Exchange may send additional P/A Orders to the same Participant Exchanges as long as such orders are, in the aggregate, for at least the lesser of 100 contracts or the entire remainder of the Customer Order; provided that the sending Participant Exchange may limit the size of any single additional P/A Order to the size of the Participant Exchange’s currently-disseminated quotation. In any situation where a receiving Participant Exchange does not execute a P/A Order in full, such exchange is required to move its quotation to a price inferior to the Reference Price of the P/A Order. (c)- (e) No change. RB8 September 7, 2005, Volume RB16, Number 36
