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 RG05-68 Date: August 15, 2005 From: Market Operations Department Re: Restrictions on Transactions in Lakes Entertainment, Inc. (LACOE/QWL) On the opening of business on August 10, 2005, Lakes Entertainment (QWL) was delisted from the Nasdaq. As of August 10, 2005, trading on CBOE in existing series of QWL options were subject to the following restrictions. Only closing transactions may be effected in any series of QWL options except for (i) opening transactions by Market-Makers executed to accommodate closing transactions of other market participants and (ii) opening transactions by CBOE member organizations to facilitate the closing transactions of public customers executed as crosses pursuant to and in accordance with CBOE Rule 6.74(b) or (d). The execution of opening transactions in QWL options, except as permitted above, and/or the misrepresentation as to whether an order is opening or closing, will constitute a violation of CBOE rules, and may result in disciplinary action. Member organizations should ensure that they have appropriate procedures in place to prevent their customers from entering opening orders in this restricted option class. There are no restrictions in place with respect to the exercise of QWL options. The provisions of this circular apply to any options on QWL traded on CBOE. Any questions regarding this circular may directed to Kerry Winters at (312) 786-7312 or Joanne Heenan-Hustad at (312) 786-7786. 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”). Copies are available on the CBOE public website at www.cboe.com/ legal/effectivefiling.aspx. The effective date of the rule change is the date of approval unless otherwise noted. SR-CBOE-2005-40 HOSS Opening Quote On August 10, 2005, the SEC approved Rule Change File No. SR-CBOE-2005-40, which proposes to allow the Hybrid Opening System (“HOSS”) to open an options series as long as any market participant, not just the DPM, has submitted an opening quote that complies with the legal width quote requirements. Any questions regarding the rule change may be directed to James Flynn, Legal Division, at 312-786-7070. The text of the amended rules is set forth below. New language is italicized. Rule 6.2B. Hybrid Opening System (“HOSS”) (a) No change. (b) After the Opening Notice is sent, the System will calculate and provide the Expected Opening Price (“EOP”) and expected opening size (“EOS”) given the current resting orders during the EOP Period (“EOP Period”). The appropriate FPC will establish the duration of the EOP Period on a class basis at between five and sixty seconds. The EOP, which will be calculated and disseminated to market participants every few seconds, is the price at which the greatest number of orders in the Book are expected to trade. After the Opening Notice is sent, quotes and orders may be submitted without restriction. An EOP may only be calculated if: (i) there are market orders in the Book, or the Book is crossed (highest bid is higher than the lowest offer) or locked (highest bid equals lowest offer), and (ii) at least one quote is present and complies with the legal width quote requirements of Rule 8.7(b)(iv). (c) - (d) No change. (e) The System will not open a series if one of the following conditions is met: (i)There is no quote present in the series that complies with the legal width quote requirements of Rule 8.7(b)(iv); (ii) The opening price is not within an acceptable range (as determined by the appropriate FPC and announced to the membership via Regulatory Circular) compared to the lowest quote offer and the highest quote bid; or (iii) (f) – (i) RB2 No change. No change. August 24, 2005, Volume RB16, Number 34 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-2005-60 Automated Improvement Mechanism (AIM) for Crossing Orders On August 4, 2005, the Exchange filed Rule Change File No. SR-CBOE-2005-60, which filing proposes to adopt an Automated Improvement Mechanism (“AIM”) for crossing orders. 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 strickenthrough]. Rule 6.45A. Priority and Allocation of Equity Option Trades on the CBOE Hybrid System Generally. The rules of priority and order allocation procedures set forth in this rule shall apply only to equity option classes designated by the Exchange to be traded on the CBOE Hybrid System and has no applicability to index option and options on ETF classes. The term “market participant” as used throughout this rule refers to a Market-Maker, an in-crowd DPM, an e-DPM, a Remote Market-Maker, and a floor broker representing orders in the trading crowd. The term “in-crowd market participant” only includes an in-crowd Market-Maker, in-crowd DPM, and floor broker representing orders in the trading crowd. (a)-(c) No change. (d) Quotes Interacting with Quotes (i) In the event that a Market-Maker’s disseminated quotes interact with the disseminated quote(s) of other Market-Makers, resulting in the dissemination of a “locked” quote (e.g., $1.00 bid - 1.00 offer), the following shall occur: (A) The Exchange will disseminate the locked market and both quotes will be deemed “firm” disseminated market quotes. (B) The Market-Makers whose quotes are locked will receive a quote update notification advising that their quotes are locked. (C) When the market locks, a [one-second] “counting period” will begin during which Market-Makers whose quotes are locked may eliminate the locked market. The duration of the counting period shall be set by the Exchange but may not exceed one-second. There shall be no counting period if at the time of the lock, an auction is in progress pursuant to Rule 6.74A. August 24, 2005, Volume RB16, Number 34 RB3 Rule Changes, Interpretations and Policies continued SR-CBOE-2005-60 continued Provided, however, that in accordance with subparagraph (A) above a MarketMaker will be obligated to execute customer and broker-dealer orders eligible for automatic execution pursuant to Rule 6.13 at his disseminated quote in accordance with Rule 8.51. If at the end of the [one-second] counting period the quotes remain locked, the locked quotes will automatically execute against each other in accordance with the allocation algorithm described above in Rule 6.45A(a). (e) No change. …Interpretations and Policies: .01 - .02. No change. ***** Rule 6.74A Automated Improvement Mechanism (“AIM”) Notwithstanding the provisions of Rule 6.74, a member that represents agency orders may electronically execute an order it represents as agent (“Agency Order”) against principal interest or against a solicited order provided it submits the Agency Order for electronic execution into the AIM auction (“Auction”) pursuant to this Rule. (a) Auction Eligibility Requirements. A member (the “Initiating Member”) may initiate an Auction provided all of the following are met: (1) the Agency Order is within the designated Auction order eligibility size parameters as such size parameters are determined by the appropriate Floor Procedure Committee; (2) if the Agency Order is for 50 contracts or more, the Initiating Member must stop the entire Agency Order as principal or with a solicited order at the better of the NBBO or the Agency Order’s limit price (if the order is a limit order); (3) if the Agency Order is for less than 50 contracts, the Initiating Member must stop the entire Agency Order as principal or with a solicited order at the better of (A) the NBBO price improved by one minimum price improvement increment, which increment shall be determined by the Exchange but may not be smaller than one cent; or (B) the Agency Order’s limit price (if the order is a limit order); and (4) at least three (3) Market-Makers are quoting in the relevant series. (b) Auction Process. Only one Auction may be ongoing at any given time in a series and Auctions in the same series may not queue or overlap in any manner. The Auction may not be canceled and shall proceed as follows: (1) Auction Period and Request for Responses (RFRs). RB4 August 24, 2005, Volume RB16, Number 34 Rule Changes, Interpretations and Policies continued SR-CBOE-2005-60 continued (A) To initiate the Auction, the Initiating Member must mark the Agency Order for Auction processing, and specify (i) a single price at which it seeks to cross the Agency Order (with principal interest or a solicited order) (a “single-price submission”), or (ii) that it is willing to automatically match as principal the price and size of all Auction responses (“auto-match”) in which case the Agency Order will be stopped at the NBBO (if 50 contracts or greater) or one cent/one minimum increment better than the NBBO (if less than 50 contracts). (B) When the Exchange receives a properly designated Agency Order for Auction processing, a Request for Responses (“RFR”) detailing the side and size of the order will be sent to all members that have elected to receive RFRs. (C) The RFR will last for a random time period that shall not be less than 3 seconds and shall not exceed 5 seconds. (D) Each Market-Maker quoting in the relevant option class may submit responses to the RFR (specifying prices and sizes). Such responses cannot cross the disseminated Exchange quote on the opposite side of the market. (E) Floor Brokers may submit responses to the RFR (specifying prices and sizes) only on behalf of orders resting at the top of the Exchange’s book (resting at the BBO) opposite the Agency Order. Such responses cannot cross the disseminated Exchange quote on the opposite side of the market, and may not exceed the size of the booked order being represented. (F) RFR responses shall not be visible to other Auction participants, and shall not be disseminated to OPRA. (G) The minimum price increment for RFR responses and for an Initiating Member’s single price submission shall not be smaller than the minimum price improvement increment established pursuant to subparagraph (a)(3) above. (H) An RFR response size at any given price point may not exceed the size of the Agency Order. (I) RFR responses may be modified or cancelled. (2) Conclusion of Auction. The Auction shall conclude at the sooner of (A) through (D) below with the Agency Order executing pursuant to paragraph (3) below. (A) The end of the RFR period; (B) Upon receipt by the Hybrid System of an unrelated order (in the same series as the Agency Order) that is marketable against either the Exchange’s disseminated quote (when such quote is the NBBO) or the RFR responses; August 24, 2005, Volume RB16, Number 34 RB5 Rule Changes, Interpretations and Policies continued SR-CBOE-2005-60 continued (C) Upon receipt by the Hybrid System of an unrelated limit order (in the same series as the Agency Order and on the opposite side of the market as the Agency Order) that improves any RFR response; or (D) Any time an RFR response matches the Exchange’s disseminated quote on the opposite side of the market. (3) Order Allocation. At the conclusion of the Auction, the Agency Order will be allocated at the best price(s) pursuant to the matching algorithm in effect for the class subject to the following: (A) Such best prices may include non-Auction quotes and orders. (B) Public customer orders in the book shall have priority. (C) No participation entitlement shall apply to orders executed pursuant to this Rule. (D) If an unrelated market order on the opposite side of the market as the Agency Order was received during the Auction and ended the Auction, such unrelated market order shall trade against the Agency Order at the midpoint of the best RFR response and the NBBO on the other side of the market (rounded towards the disseminated quote when necessary). (E) If an unrelated limit order on the opposite side of the market as the Agency Order was received during the Auction and ended the Auction, such unrelated limit order shall trade against the Agency Order at the midpoint of the best RFR response and the unrelated order’s limit price (rounded towards the unrelated order’s limit price when necessary). (F) If the best price equals the Initiating Member’s single-price submission, the Initiating Member’s single-price submission shall be allocated the greater of one contract or 40% of the order. However, if only one Market-Maker matches the Initiating Member’s single price submission then the Initiating Member shall be allocated 50% of the order. (G) If the Initiating Member selected the auto-match option of the Auction, the Initiating Member shall be allocated its full size at each price point until a price point is reached where the balance of the order can be fully executed. At such price point, the Initiating Member shall be allocated the greater of one contract or 40% of the remainder of the order. RB6 August 24, 2005, Volume RB16, Number 34 Rule Changes, Interpretations and Policies continued SR-CBOE-2005-60 continued (H) If the Auction does not result in price improvement over the Exchange’s disseminated price at the time the Auction began, resting unchanged quotes or orders that were disseminated at the best price before the Auction began shall have priority after any public customer order priority and the Initiating Member’s priority (40%) have been satisfied. Any unexecuted balance on the Agency Order shall be allocated to RFR responses provided that those RFR responses will be capped to the size of the unexecuted balance and that the Initiating Member may not participate on any such balance unless the Agency Order would otherwise go unfilled. (I) If the final Auction price locks a customer order in the book on the same side of the market as the Agency Order, then, unless there is sufficient size in the Auction responses to execute both the Agency Order and the booked customer order (in which case they will both execute at the final Auction price), the Agency Order will execute against the RFR responses at one minimum RFR response increment worse than the final Auction price against the Auction participants that submitted the final Auction price and any balance shall trade against the customer order in the book at such order’s limit price. If an unexecuted balance remains on the Auction responses after the Agency Order has been executed and such balance could trade against any unrelated order(s) that caused the Auction to conclude, then the RFR balance will trade against the unrelated order(s). …Interpretations and Policies: .01 The Auction may be used only where there is a genuine intention to execute a bona fide transaction. .02 A pattern or practice of submitting unrelated orders that cause an Auction to conclude before the end of the RFR period may be deemed conduct inconsistent with just and equitable principles of trade and a violation of Rule 4.1 and other Exchange Rules. .03 Initially, and for at least a Pilot Period expiring on July 18, 2006, there will be no minimum size requirement for orders to be eligible for the Auction.

Nullification and Adjustment of Equity Options Transactions This Rule governs the nullification and adjustment of transactions involving equity options. Rule 24.16 governs the nullification and adjustment of transactions involving index options and options on ETFs and HOLDRs. Paragraphs (a)(1), and (2) of this Rule have no applicability to trades executed in open outcry. (a) Trades Subject to Review A member or person associated with a member may have a trade adjusted or nullified if, in addition to satisfying the procedural requirements of paragraph (b) below, one of the following conditions is satisfied: (1) Obvious Price Error: An obvious pricing error occurs when the execution price of an electronic transaction is above or below the Theoretical Price for the series by an amount equal to at least the amount shown below: RB8 Theoretical Price Minimum Amount Below $2 $0.25 $2 to $5 $0.40 Above $5 to $10 $0.50 Above $10 to $20 $0.80 Above $20 $1.00 August 24, 2005, Volume RB16, Number 34 Rule Changes, Interpretations and Policies continued SR-CBOE-2005-63 continued Definition of Theoretical Price. For purposes of this Rule only, the Theoretical Price of an option series is, for series traded on at least one other options exchange, the last bid price with respect to an erroneous sell transaction and the last offer price with respect to an erroneous buy transaction, just prior to the trade, disseminated by the competing options exchange that has the most liquidity in that option class in the previous two calendar months. If there are no quotes for comparison, designated Trading Officials will determine the Theoretical Price. For transactions occurring as part of the Rapid Opening System (“ROS trades”) or Hybrid Opening System (“HOSS”), Theoretical Price shall be the first quote after the transaction(s) in question that does not reflect the erroneous transaction(s). Price Adjustment or Nullification: Obvious Pricing Errors will be adjusted or nullified in accordance with (i), (ii), (iii) or (iv) below or any combination thereof [the following]: (i) Transactions Between CBOE Market-Makers: Where both parties to the transaction are CBOE Market-Makers, the execution price of the transaction will be adjusted by Trading Officials to the prices provided in Paragraphs (A) and (B) below, minus (plus) an adjustment penalty (“adjustment penalty”), unless both parties agree to adjust the transaction to a different price or agree to bust the trade within fifteen (15) minutes of being notified by Trading Officials of the Obvious Error. A. Erroneous buy transactions will be adjusted to their Theoretical Price plus an adjustment penalty of either $.15 if the Theoretical Price is under $3 or $.30 if the Theoretical Price is at or above $3. B. Erroneous sell transactions will be adjusted to their Theoretical Price minus an adjustment penalty of either $.15 if the Theoretical Price is under $3 or $.30 if the Theoretical Price is at or above $3. (ii) Transactions Between a non-broker-dealer Customer and CBOE MarketMaker(s): After the fifteen minute notification period as described in (b)(1) below and until 3:30 P.M. on the subject trade date, where parties to the transaction are a non-broker-dealer Customer and CBOE Market-Maker(s), the non-broker-dealer Customer may request review of the subject transaction, and the execution price of the transaction will be adjusted (provided the adjustment does not violate the customer’s limit price) by Trading Officials to the prices provided in Paragraphs (A) and (B) above, without the adjustment penalty, unless both parties agree to adjust the transaction to a different price or agree to bust the trade within fifteen (15) minutes of being notified by Trading Officials of the Obvious Error. The option contract quantity of any adjustment shall not exceed the disseminated size by the competing options exchange that has the most liquidity in that option class in the previous two calendar months. In the event a non-CBOE Market-Maker is also party to the transaction, the adjustment procedures described below shall apply. (iii) Transactions Between a non-broker-dealer Customer and at least one nonCBOE Market-Maker(s): After the fifteen minute notification period as described in (b)(1) below and until 3:30 P.M. on the subject trade date, where parties to the transaction are a non-broker-dealer Customer and a non-CBOE Market-Maker(s), the non-broker-dealer Customer may request review of the subject transaction and, the execution price of the transaction will be adjusted (provided the adjustment does not violate non-CBOE Market-Maker’s limit price) by Trading Officials to the prices provided in Paragraphs (A) and (B) above, without the adjustment penalty, unless both parties agree to adjust the transaction to a different price or agree to bust the trade within fifteen (15) minutes of being notified by Trading Officials of the Obvious Error. The adjustment price shall not exceed the non-CBOE Market-Maker’s limit price. The option contract quantity of any adjustment shall not exceed the disseminated size by the competing options exchange that has the most liquidity in that option class in the previous two calendar months.
