I. Self-Regulatory Organization's Statement of the Terms of Substance
of the Proposed Rule Change

    Nasdaq is proposing to integrate the operations of the existing
Nasdaq Market Center, along with Nasdaq's Brut Facility and Nasdaq's
INET Facility to create the fairest, fastest, most efficient and most
transparent system in Nasdaq's 35-year history. This integration will
benefit investors by creating a single pool of liquidity from three,
thereby increasing order interaction, and execution speed and fill
rates. Integration will enable Nasdaq to further reduce the cost to
investors of executing trades on Nasdaq by, for example, reducing the
cost for subscriber connectivity and increasing the efficiency of the
resulting facility.
    Nasdaq is currently on schedule to launch the proposed integrated
system timely to comply with the requirements of the Fair Access and
Order Protection rules, Rules 610 and 611 of Regulation NMS under the
Act (``Regulation NMS''). The integrated system will be designed to
enable Nasdaq to operate its execution system as that of a national
securities exchange rather than as an association, pursuant to the
Commission order, dated January 13, 2006, approving Nasdaq's
application to register as a national securities exchange.\4\ Below is
the text of the proposed rule change. Proposed new language is
italicized and proposed deletions are in [brackets].

2006), 71 FR 3550 (January 23, 2006) (``January 13, 2006 Order'').

4120. Trading Halts

(a) Authority To Initiate Trading Halts
    In circumstances in which Nasdaq deems it necessary to protect
investors and the public interest, Nasdaq may, pursuant to the
procedures set forth in paragraph (b):
    (1) Halt trading on Nasdaq of a Nasdaq-listed security to permit
the dissemination of material news; or
    (2) Halt trading on Nasdaq of a security listed on another national
securities exchange during a trading halt imposed by such exchange to
permit the dissemination of material news; or
    (3) Halt trading [by] on Nasdaq: (i) [ITS/CAES Market Makers] in a
security listed on another national securities exchange when such
exchange imposes a trading halt in that security because of an order
imbalance or influx (``operational trading halt''); or (ii) [Nasdaq
market makers] in a security listed on Nasdaq, when the security is a
derivative or component of a security listed on another national
securities exchange and such exchange imposes an operational trading
halt in that security. [ITS/CAES Market Makers and] In the event that
Nasdaq halts trading, Nasdaq Participants [Market Makers] may commence
quotations and trading at any time following initiation of operational
trading halts, without regard to procedures for resuming trading set
forth in paragraph (b); or
    (4) Halt trading in an American Depository Receipt (``ADR'') or
other security listed on Nasdaq, when the Nasdaq-listed security or the
security underlying the ADR is listed on or registered with another
national or foreign securities exchange or market, and the national or
foreign securities exchange or market, or regulatory authority
overseeing such exchange or market, halts trading in such security for
regulatory reasons; or
    (5) Halt trading in a security listed on Nasdaq when Nasdaq
requests from the issuer information relating to:
    (A) Material news;
    (B) The issuer's ability to meet Nasdaq listing qualification
requirements, as set forth in the Rule 4300, 4400, and 4800 Series; or
    (C) Any other information which is necessary to protect investors
and the public interest.
    (6) Halt trading in a security listed on Nasdaq when
    (A) Extraordinary market activity in the security is occurring,
such as the execution of a series of transactions for a significant
dollar value at prices substantially unrelated to the current market
for the security, as measured by the national best bid and offer, and
    (B) Nasdaq determines that such extraordinary market activity is
likely to have a material effect on the market for the security; and
    (C)(i) Nasdaq believes that such extraordinary market activity is
caused by the misuse or malfunction of an electronic quotation,
communication, reporting, or execution system operated by, or linked
to, Nasdaq;
    (ii) After consultation with another national securities exchange
trading the security on an unlisted trading privileges basis, Nasdaq
believes that such extraordinary market activity is caused by the
misuse or malfunction of an electronic quotation, communication,
reporting, or execution system operated

by, or linked to, such other national securities exchange; or
    (iii) After consultation with NASD regarding an NASD facility
trading the security, Nasdaq believes that such extraordinary market
activity is caused by the misuse or malfunction of such NASD facility
or an electronic quotation, communication, reporting, or execution
system linked to such NASD facility.
    (7) Halt trading in a security that is the subject of an Initial
Public Offering on Nasdaq.
(b) Procedure for Initiating a Trading Halt
    (1) Nasdaq issuers are required to notify Nasdaq of the release of
certain material news prior to the release of such information to the
public as required by Rules 4310(c)(16) and 4320(e)(14).
    (2) Notification shall be provided directly to Nasdaq's MarketWatch
Department by telephone, facsimile, or other compatible means of
electronic communication.\5\ Information communicated orally by
authorized representatives of a Nasdaq issuer should be confirmed
promptly in writing.
---------------------------------------------------------------------------

    \5\ Notification may be provided to the MarketWatch Department
by telephone 1-800-537-3929 and<PHONE_NUMBER>. Between 7 p.m. and
7:30 a.m. eastern time, voice mail messages may be left on either
number. The fax number is<PHONE_NUMBER>.
---------------------------------------------------------------------------

    (3) Upon receipt of information, from the issuer or other source,
Nasdaq will promptly evaluate the information, estimate its potential
impact on the market and determine whether a trading halt in the
security is appropriate.
    (4) Should Nasdaq determine that a basis exists under Rule 4120(a)
for initiating a trading halt, the commencement of the trading halt
will be effective at the time specified by Nasdaq in a notice posted on
a publicly available Nasdaq Web site. In addition, Nasdaq shall
disseminate notice of the commencement of a trading halt through major
wire services.
    (5) Trading in a halted security shall resume at the time specified
by Nasdaq in a notice posted on a publicly available Nasdaq Web site.
In addition, Nasdaq shall disseminate notice of the resumption of
trading through major wire services.
    (6)(i) In the case of a trading halt under Rule 4120(a)(6) based on
the misuse or malfunction of an electronic quotation, communication,
reporting, or execution system that is not operated by Nasdaq, Nasdaq
will promptly contact the operator of the system in question (as well
as any national securities exchange or NASD facility to which such
system is linked) to ascertain information that will assist Nasdaq in
determining whether a misuse or malfunction has occurred, what effect
the misuse or malfunction is having on trading in a security, and what
steps are being taken to address the misuse or malfunction. If the
operator of the system is unavailable when contacted by Nasdaq, Nasdaq
will continue efforts to contact the operator of the system to
ascertain information that will assist Nasdaq in determining whether
the trading halt should be terminated.
    (ii) A trading halt initiated under Rule 4120(a)(6) shall be
terminated as soon as Nasdaq determines either that the system misuse
or malfunction that caused the extraordinary market activity will no
longer have a material effect on the market for the security or that
system misuse or malfunction is not the cause of the extraordinary
market activity.
    (7)(a) A trading halt initiated under Rule 4120(a)(1), (4), (5) or
(6) shall be terminated when Nasdaq releases the security for trading.
Prior to terminating the halt, there will be a 5-minute Display Only
Period during which market participants may enter quotations and orders
in that security in Nasdaq systems. At the conclusion of the 5-minute
Display Only Period, the security shall be released for trading unless
Nasdaq extends the Display Only Period for an additional 1-minute
period pursuant to subparagraph (c) below. There shall be a period of
between zero and 15 seconds (randomly selected) at which point the
Display Only Period shall end and trading shall resume pursuant to Rule
4753.
     (b) A trading halt initiated under Rule 4120(a)(7) shall be
terminated when Nasdaq releases the security for trading. Prior to
terminating the halt, there will be a 15-minute Display Only P[p]eriod
during which market participants may enter quotes and orders in that
security in Nasdaq systems. At the conclusion of the 15-minute Display
Only P[p]eriod, [the halt shall be terminated and the security released
for trading.] the security shall be released for trading unless Nasdaq
extends the Display Only Period for one, two or three additional 5-
minute Display Only Periods pursuant to subparagraph (c) below. At the
conclusion of the Display Only Period(s), there shall be an additional
delay of between zero and 15 seconds (randomly selected) and then
trading shall resume pursuant to Rule 4753.
    (c) If at the end of a Display Only Period, Nasdaq detects a
liquidity imbalance in the security. Nasdaq will extend the Display
Only Period as permitted under subparagraphs (a) and (b) above.
Liquidity Imbalances shall be established when (1) the Current
Reference Prices, as defined in Rule 4705(a)(2), disseminated 15
seconds and immediately prior to the end of the Display Only Period
differ by greater than (i) 10 percent or (ii) 50 cents (whichever is
greater), or (2) all buy or sell market orders will not be executed in
the cross.

necessary to protect the integrity of Nasdaq's systems. For example,

traffic. The scope of any such restrictions shall be communicated to
the affected Nasdaq Market Maker, Nasdaq ECN or Order Entry Firm in
writing.

4612. Registration as a Nasdaq Market Maker

    (a) Quotations and quotation sizes may be entered into the Nasdaq
Market Center only by a member registered as a Nasdaq Market Maker or
other entity approved by Nasdaq to function in a market-making
capacity.

interface with Nasdaq's systems or by contacting Nasdaq Market
Operations. Registration shall become effective on the day the

    (c) A Nasdaq Market Maker's registration in an issue shall be
terminated by Nasdaq if the market maker fails to enter quotations in

registration in the issue becomes effective.
    [(d) In cases where a Nasdaq Market Maker has more than one trading
location, a fifth character geographic indicator shall be appended to
the Nasdaq Market Maker's identifier for that security to identify the
branch location where the security is traded. The fifth-character
branch indicators are established by Nasdaq and published from time to
time in the Nasdaq symbol directory.]

4613. Character of Quotations

    A member registered as a Nasdaq Market Maker shall engage in a
course of dealings for its own account to assist in the maintenance,
insofar as reasonably practicable, of fair and orderly markets in
accordance with this Rule.
(a) Quotation Requirements and Obligations
    (1) Two-Sided Quote Obligation. For each security in which a member
is registered as a Nasdaq Market Maker, the member shall be willing to
buy and sell such security for its own account on a continuous basis
and shall enter and maintain a two-sided quotation (``Principal
Quote''), which is attributed to the market maker by a special maker
participant identifier (``MPID'') and is displayed in the Nasdaq Market
Center at all times, subject to the procedures for excused withdrawal
set forth in Rule 4619.
    (A) A registered market maker [in a Nasdaq-listed security] must
display a quotation size for at least one normal unit of trading (or a
larger multiple thereof) when it is not displaying a limit order in
compliance with SEC Rule 604, provided, however, that a registered
Nasdaq Market Maker may augment its

displayed quotation size to display limit orders priced at the market
maker's quotation. Unless otherwise designated, a ``normal unit of
trading'' shall be 100 shares.
    (B) [Minimum Price Variation for Decimal-based Quotations--The
minimum quotation increment for Nasdaq securities authorized for
decimal pricing shall be $0.01. Quotations failing to meet this
standard shall be rejected.] The minimum quotation increment for
quotations of $1.00 or above in all System Securities shall be $0.01.
The minimum quotation increment in the System for quotations below
$1.00 in System Securities shall be $0.0001.
(b) Firm Quotations
    (1) All quotations and orders to buy or sell entered into the
System by Nasdaq Market Makers, Nasdaq ECNs, and Nasdaq Order Entry
firms are firm and automatically executable for their displayed and
non-displayed size in the System. [A Nasdaq Market Maker that receives
an offer to buy or sell from another member shall execute a transaction
for at least a normal unit of trading at its displayed quotations as
disseminated in the Nasdaq Market Center at the time of receipt of any
such offer. If a Nasdaq Market Maker displays a quotation for a size
greater than a normal unit of trading, it shall, upon receipt of an
offer to buy or sell from another member, execute a transaction at
least at the size displayed.]
    [(2) If a Nasdaq Market Maker, upon receipt of an offer to buy or
sell from another member in any amount that is at least one normal unit
of trading greater than its published quotation size as disseminated in
the Nasdaq Market Center at the time of receipt of any such offer,
executes a transaction in an amount of shares less than the size of the
offer, then such market maker shall, immediately after such execution,
display a revised quotation at a price that is inferior to its previous
published quotation. The failure of a Nasdaq Market Maker to execute
the offer in an amount greater than its published quotation size shall
not constitute a violation of subparagraph (c) of this rule.]
(c) Quotations Reasonably Related to the Market
    A Nasdaq Market Maker shall enter and maintain quotations that are
reasonably related to the prevailing market. Should it appear that a
market maker's quotations are no longer reasonably related to the
prevailing market, Nasdaq may require the market maker to re-enter its
quotations. If a Nasdaq Market Maker whose quotations are no longer
reasonably related to the prevailing market fails to re-enter its
quotations, Nasdaq may suspend the market maker's quotations in one or
all securities.
    In the event that a Nasdaq Market Maker's ability to enter or
update quotations is impaired, the market maker shall immediately
contact Nasdaq Market Operations to request the withdrawal of its
quotations.
    In the event that a Nasdaq Market Maker's ability to enter or
update quotations is impaired and the market maker elects to remain in
Nasdaq, the Nasdaq Market Maker shall execute an offer to buy or sell
received from another member at its quotations as disseminated through
the Nasdaq Market Center.
    (d) Reserved
    (e) Locked and Crossed Markets
    (1) Locked and Cross Markets within the System: Any quotes or
orders that are entered into the System that would lock or cross
another order in the System will be executed by the System. This
processing, set forth in Rule 4757, ensures that no locked or crossed
markets can exist within the System and that price improvement is
allocated fairly.
    (2) Inter-market Locked and Crossed Markets
    (A) Definitions. For purposes of this Rule, the following
definitions shall apply:
    (i) The terms automated quotation, effective national market system
plan, intermarket sweep order, manual Quotation, NMS stock, protected
quotation, regular trading hours, and trading center shall have the
meanings set forth in Rule 600(b) of Regulation NMS under the
Securities Exchange Act of 1934.
    (ii) The term crossing quotation shall mean the display of a bid
for an NMS stock during regular trading hours at a price that is higher
than the price of an offer for such NMS stock previously disseminated
pursuant to an effective national market system plan, or the display of
an offer for an NMS stock during regular trading hours at a price that
is lower than the price of a bid for such NMS stock previously
disseminated pursuant to an effective national market system plan.
    (iii) The term locking quotation shall mean the display of a bid
for an NMS stock during regular trading hours at a price that equals
the price of an offer for such NMS stock previously disseminated
pursuant to an effective national market system plan, or the display of
an offer for an NMS stock during regular trading hours at a price that
equals the price of a bid for such NMS stock previously disseminated
pursuant to an effective national market system plan.
    (B) Prohibition. Except for quotations that fall within the
provisions of paragraph (D) of this Rule, Nasdaq members shall
reasonably avoid displaying, and shall not engage in a pattern or
practice of displaying any quotations that lock or cross a protected
quotation, and any manual quotations that lock or cross a quotation
previously disseminated pursuant to an effective national market system
plan.
    (C) Manual Quotations. If a member of the Exchange displays a
manual quotation that locks or crosses a quotation previously
disseminated pursuant to an effective national market system plan, such
member of the Exchange shall promptly either withdraw the manual
quotation or route an intermarket sweep order to execute against the
full displayed size of the locked or crossed quotation.
    (D) Exceptions.
    (i) The locking or crossing quotation was displayed at a time when
the trading center displaying the locked or crossed quotation was
experiencing a failure, material delay, or malfunction of its systems
or equipment.
    (ii) The locking or crossing quotation was displayed at a time when
a protected bid was higher than a protected offer in the NMS stock.
    (iii) The locking or crossing quotation was an automated quotation,
and the Nasdaq member displaying such automated quotation
simultaneously routed an intermarket sweep order to execute against the
full displayed size of any locked or crossed protected quotation.
    (iv) The locking or crossing quotation was a manual quotation that
locked or crossed another manual quotation, and the member of the
Exchange displaying the locking or crossing manual quotation
simultaneously routed an intermarket sweep order to execute against the
full displayed size of the locked or crossed manual quotation.
    [(1) A Nasdaq Market Maker shall not, except under extraordinary
circumstances, enter or maintain quotations in Nasdaq during normal
business hours if:
    (A) The bid quotation entered is equal to (``lock'') or greater
than (``cross'') the asked quotation of another Nasdaq Market Maker
entering quotations in the same security; or
    (B) The asked quotation is equal to (``lock'') or less than
(``cross'') the bid quotation of another Nasdaq Market Maker entering
quotations in the same security.

    (2) A Nasdaq Market Maker shall, prior to entering a quotation that
locks or crosses another quotation, make reasonable efforts to avoid
such locked or crossed market by executing transactions with all Nasdaq
Market Makers whose quotations would be locked or crossed. Pursuant to
the provisions of paragraph (b) of this Rule, a Nasdaq Market Maker
whose quotations are causing a locked or crossed market is required to
execute transactions at its quotations as displayed through Nasdaq at
the time of receipt of any order.
    (3) For purposes of this rule, the term ``market maker'' shall
include:
    (A) Any Nasdaq member that enters into an ECN, as that term is
defined in SEC Rule 600, a priced order that is displayed in the Nasdaq
Market Center;
    (B) Any Nasdaq member that operates the ECN when the priced order
being displayed has been entered by a person or entity that is not a
Nasdaq member;
    (C) Any Nasdaq member that enters into an ATS, as that term is
defined in SEC Regulation ATS, an order that is displayed in the Nasdaq
Market Center; and
    (D) Any Nasdaq member that operates the ATS when the order being
displayed has been entered by a person or entity that is not a Nasdaq
member.]

Makers whose quotes are open prior to 9:30 a.m. Eastern time or after 4
p.m. eastern time shall be obligated to comply, while their quotes are

an official interpretation of Nasdaq, inapplicable to any part of the 7
a.m. to 9:30 a.m. or 4 p.m. to [6:30] 8 p.m. eastern time period.

4618. Clearance and Settlement

    (a) All transactions through the facilities of the Nasdaq Market
Center shall be cleared and settled through a registered clearing
agency using a continuous net settlement system. This requirement may
be satisfied by direct participation, use of direct clearing services,
or by entry into a correspondent clearing arrangement with another
member that clears trades through such an agency.
    (b) Notwithstanding paragraph (a), transactions in Nasdaq listed
securities may be settled ``ex-clearing'' provided that both parties to
the transaction agree.

4619. Withdrawal of Quotations and Passive Market Making

    (a) Except as provided in paragraph (b) of this Rule, a market
maker that wishes to withdraw quotations in a security or have its
quotations identified as the quotations of a passive market maker shall
contact Nasdaq MarketWatch to obtain excused withdrawal status prior to
withdrawing its quotations or identification as a passive market maker.
Withdrawals of quotations or identifications of quotations as those of
a passive market maker shall be granted by Nasdaq MarketWatch only upon
satisfying one of the conditions specified in this Rule.
    (b) A Nasdaq Market Maker that wishes to obtain excused withdrawal
status based on a market maker's systemic equipment problems, such as
defects in a Nasdaq Market Maker's software or hardware systems or
connectivity problems associated with the circuits connecting Nasdaq
Market Center systems with the Nasdaq Market Maker's systems, shall
contact Nasdaq Market Operations. Nasdaq Market Operations may grant
excused withdrawal status based on systemic equipment problems for up
to five (5) business days, unless extended by Nasdaq Market Operations.
    (c)(1) For Nasdaq-listed securities, e[E]xcused withdrawal status
based on circumstances beyond the Nasdaq Market Maker's control, other
than systemic equipment problems, may be granted for up to five (5)
business days, unless extended by Nasdaq MarketWatch. Excused
withdrawal status based on demonstrated legal or regulatory
requirements, supported by appropriate documentation and accompanied by
a representation that the condition necessitating the withdrawal of
quotations is not permanent in nature, may, upon

notification, be granted for not more than sixty (60) days (unless such
request is required to be made pursuant to paragraph (e) below).
Excused withdrawal status based on religious holidays may be granted
only if written notice is received by Nasdaq one business day in
advance and is approved by Nasdaq. Excused withdrawal status based on
vacation maybe granted only if:
    ([1]A) The written request for withdrawal is received by Nasdaq one

    ([3]C) The request is made by a Nasdaq Market Maker with three (3)
or fewer Nasdaq level 3 terminals. Excused withdrawal status may be
granted to a Nasdaq Market Maker that has withdrawn from an issue prior
to the public announcement of a merger or acquisition and wishes to re-
register in the issue pursuant to the same-day registration procedures
contained in Rule 4611 above, provided the Nasdaq Market Maker has
remained registered in one of the affected issues. The withdrawal of
quotations because of pending news, a sudden influx of orders or price
changes, or to effect transactions with competitors shall not
constitute acceptable reasons for granting excused withdrawal status.
    (2) For ITS Securities, a Nasdaq Market Maker that wishes to
withdraw quotations shall contact Nasdaq MarketWatch to obtain excused
withdrawal status prior to withdrawing its quotations. Excused
withdrawal status based on illness, vacations or physical circumstances
beyond the Market Maker's control may be granted for up to five (5)
business days, unless extended by Nasdaq MarketWatch. Excused
withdrawal status based on investment activity or advice of legal
counsel, accompanied by a representation that the condition
necessitating the withdrawal of quotations is not permanent in nature,
may, upon written request, be granted for not more than sixty (60)
days. The withdrawal of quotations because of pending news, a sudden
influx of orders or price changes, or to effect transactions with
competitors shall not normally constitute acceptable reasons for
granting excused withdrawal status, unless Nasdaq has initiated a
trading halt for Market Makers in the security. pursuant to Rule 4120.
    (d) Excused withdrawal status may be granted to a Nasdaq Market
Maker that fails to maintain a clearing arrangement with a registered
clearing agency or with a member of such an agency and is withdrawn
from participation in the trade reporting service of the Nasdaq Market
Center, thereby terminating its registration as a Nasdaq Market Maker.
Provided however, that if Nasdaq finds that the Nasdaq Market Maker's
failure to maintain a clearing arrangement is voluntary, the withdrawal
of quotations will be considered voluntary and unexcused pursuant to
Rule 4620 and the Rule 4700 Series governing the Nasdaq Market Center.
Nasdaq Market Makers that fail to maintain a clearing relationship will
have their Nasdaq Market Center system status set to ``suspend'' and be
thereby prevented from entering, or executing against, any quotes/
orders in the system.
    (e) Excused withdrawal status or passive market maker status may be
granted to a Nasdaq Market Maker that is a distribution participant
(or, in the case of excused withdrawal status, an affiliated purchaser)
in order to comply with SEC Rule 101, 103, or 104 under the Act on the
following conditions:
    (1) A member acting as a manager (or in a similar capacity) of a
distribution of a security that is a subject security or reference
security under SEC Rule 101 and any member that is a distribution
participant or an affiliated purchaser in such a distribution that does
not have a manager shall provide written notice to Nasdaq MarketWatch
and the Market Regulation Department of NASD Regulation, Inc. no later
than the business day prior to the first entire trading session of the
one-day or five-day restricted period under SEC Rule 101, unless later
notification is necessary under the specific circumstances.
    (A) The notice required by subparagraph (e)(1) of this Rule shall
be provided by submitting a completed Underwriting Activity Report that
includes a request on behalf of each Nasdaq Market Maker that is a
distribution participant or an affiliated purchaser to withdraw the
Nasdaq Market Maker's quotations, or that includes a request on behalf
of each Nasdaq Market Maker that is a distribution participant (or an
affiliated purchaser of a distribution participant) that its quotations
be identified as those of a passive market maker and includes the
contemplated date and time of the commencement of the restricted
period.
    (B) The managing underwriter shall advise each Nasdaq Market Maker
that it has been identified as a distribution participant or an
affiliated purchaser to Nasdaq MarketWatch and that its quotations will
be automatically withdrawn or identified as passive market maker
quotations, unless a market maker that is a distribution participant
(or an affiliated purchaser of a distribution participant) notifies
Nasdaq MarketWatch as required by subparagraph (e)(2), below.
    (2) A Nasdaq Market Maker that has been identified to Nasdaq
MarketWatch as a distribution participant (or an affiliated purchaser
of a distribution participant) shall promptly notify Nasdaq MarketWatch
and the manager of its intention not to participate in the prospective
distribution or not to act as a passive market maker in order to avoid
having its quotations withdrawn or identified as the quotations of a
passive market maker.
    (3) If a Nasdaq Market Maker that is a distribution participant
withdraws its quotations in a Nasdaq security in order to comply with
the net purchases limitation of SEC Rule 103 or with any other
provision of SEC Rules 101, 103, or 104 and promptly notifies Nasdaq
MarketWatch of its action, the withdrawal shall be deemed an excused
withdrawal. Nothing in this subparagraph shall prohibit Nasdaq from
taking such action as is necessary under the circumstances against a
member and its associated persons for failure to contact Nasdaq
MarketWatch to obtain an excused withdrawal as required by
subparagraphs (a) and (e) of this Rule.
    (4) The quotations of a passive market maker shall be identified on
Nasdaq as those of a passive market maker.
    (5) A member acting as a manager (or in a similar capacity of a
distribution subject to subparagraph (e)(1) of this Rule shall submit a
request to Nasdaq MarketWatch and the Market Regulation Department of
NASD Regulation, Inc. to rescind the excused withdrawal status or
passive market making status of distribution participants and
affiliated purchasers, which request shall include the date and time of
the pricing of the offering, the offering price, and the time the
offering terminated, and, if not in writing, shall be confirmed in
writing no later than the close of business the day the offering
terminates. The request by this subparagraph may be submitted on the
Underwriting Activity Report.
    (f) The Market Operations Review Committee shall have jurisdiction
over proceedings brought by Nasdaq Market Makers seeking review of the
denial of an excused withdrawal pursuant to this Rule 4619, or the
conditions imposed on their reentry.

4620. Voluntary Termination of Registration

    (a) A market maker may voluntarily terminate its registration in a
security by withdrawing its two-sided quotation

from the Nasdaq Market Center. A Nasdaq Market Maker that voluntarily
terminates its registration in a security may not re-register as a
market maker in that security for twenty (20) business days in the case
of Nasdaq-listed securities or for one (1) business day in the case of
ITS securities. Withdrawal from participation as a Nasdaq Market Maker
in the Nasdaq Market Center shall constitute termination of
registration as a market maker in that security for purposes of this
Rule; provided, however, that a Nasdaq Market Maker that fails to
maintain a clearing arrangement with a registered clearing agency or
with a member of such an agency and is withdrawn from participation in
the Nasdaq Market Center and thereby terminates its registration as a
Nasdaq Market Maker may register as a market maker at any time after a
clearing arrangement has been reestablished unless Nasdaq finds that
the Nasdaq Market Maker's failure to maintain a clearing arrangement is
voluntary, in which case the withdrawal of quotations will be
considered voluntary and unexcused.
    (b) Notwithstanding the above, a Nasdaq Market Maker that
accidentally withdraws as a Nasdaq Market Maker may be reinstated if:
    (1) The Nasdaq Market Maker notified MarketWatch of the accidental
withdrawal as soon as practicable under the circumstances, but within
at least one hour of such withdrawal, and immediately thereafter
provided written notification of the withdrawal and reinstatement
request;
    (2) It is dear that the withdrawal was inadvertent and the market
maker was not attempting to avoid its market making obligations; and
    (3) The Nasdaq Market Maker's firm would not exceed the following
reinstatement limitations:
    (A) For firms that simultaneously made markets in less than 250
stocks during the previous calendar year, the firm can receive no more
than two (2) reinstatements per year;
    (B) For firms that simultaneously made markets in 250 or more but
less than 500 stocks during the previous calendar year, the firm can
receive no more than three (3) reinstatements per year; and
    (C) For firms that simultaneously made markets in 500 or more
stocks during the previous calendar year, the firm can receive no more
than six (6) reinstatements per year.
    (c) Factors that Nasdaq will consider in granting a reinstatement
under paragraph (b) of this rule include, but are not [be] limited to:
    (1) The number of accidental withdrawals by the Nasdaq Market Maker
in the past, as compared with Nasdaq Market Makers making markets in a
comparable number of stocks;
    (2) The similarity between the symbol of the stock that the Nasdaq
Market Maker intended to withdraw from and the symbol of the stock that
the Nasdaq Market Maker actually withdrew from;
    (3) Market conditions at the time of the withdrawal;
    (4) Whether, given the market conditions at the time of the
withdrawal, the withdrawal served to reduce the exposure of the
member's position in the security at the time of the withdrawal to
market risk; and
    (5) The timeliness with which the Nasdaq Market Maker notified
MarketWatch of the error.
    (d) For purposes of paragraph (a) of this Rule, a market maker
shall not be deemed to have voluntarily terminated its registration in
a security by voluntarily withdrawing its two-sided quotation from the
Nasdaq Market Center if the Nasdaq Market Maker's two-sided quotation
in the subject security is withdrawn by Nasdaq's systems due to issuer
corporate action related to a dividend, payment or distribution, or due
to a trading halt, and one of the following conditions is satisfied:
    (1) The Nasdaq Market Maker enters a new two-sided quotation prior
to the close of the regular market session on the same day when
Nasdaq's systems withdrew such a quotation;
    (2) The Nasdaq Market Maker enters a new two-sided quotation on the
day when trading resumes following a trading halt, or, if the
resumption of trading occurs when the market is not in regular session,
the Nasdaq Market Maker enters a new two-sided quotation prior to the
opening of the next regular market session; or
    (3) Upon request from the market maker, Nasdaq MarketWatch
authorizes the market maker to enter a new two-sided quotation,
provided that Nasdaq MarketWatch receives the market maker's request
prior to the close of the regular market session on the next regular
trading day after the day on-which the market maker became eligible to
re-enter a quotation pursuant to subparagraph (d)(1) or (d)(2) hereof
and determines that the market maker was not attempting to avoid its
market making obligations by failing to re-enter such a quotation
earlier.
    (e) The Market Operations Review Committee shall have jurisdiction
over proceedings 29 brought by market makers seeking review of their
denial of a reinstatement pursuant to paragraphs (b) or (d) of this
Rule.

4621. Suspension and Termination of Quotations

    Nasdaq may, pursuant to the procedures set forth in the Rule 9000
Series, suspend, condition, limit, prohibit or terminate the authority
of a Nasdaq Market Maker, Nasdaq ECN, or Order Entry Firm [or ITS/CAES
Market Maker] to enter quotations in one or more authorized securities
for violations of applicable requirements or prohibitions.

4622. Termination of Nasdaq Service

    Nasdaq may, upon notice, terminate Nasdaq service in the event that
a Nasdaq Market Maker, Nasdaq ECN, or Order Entry Firm [or ITS/CAES
Market Maker] fails to qualify under specified standards of eligibility
or fails to pay promptly for services rendered by Nasdaq.

4623. Alternative Trading Systems

    (a) Nasdaq may provide a means to permit alternative trading
systems (``ATSs''), as such term is defined in Regulation ATS, and
electronic communications networks (``ECNs''), as such term is defined
in SEC Rule 600,
    (1) To comply with SEC Rule 301(b)(3);
    (2) To comply with the terms of the ECN display alternative
provided for in SEC Rule 602(b)(5)(ii)(A) and (B) (``ECN display
alternatives''); or
    (3) To provide orders to Nasdaq voluntarily.
    In providing any such means, Nasdaq shall establish a mechanism
that permits the ATS or ECN to display the best prices and sizes of
orders entered into the ATS or ECN by [Nasdaq market makers (and other]
subscribers of the ATS or ECN, if the ECN or ATS so chooses or is
required by SEC Rule 301(b)(3) to display a subscriber's order in
Nasdaq[)], and allows any Nasdaq member the electronic ability to
effect a transaction with such priced orders that is equivalent to the
ability to effect a transaction with a Nasdaq market maker quotation in
Nasdaq operated systems.
    (b) An ATS or ECN that seeks to utilize the Nasdaq-provided means
to comply with SEC Rule 301(b)(3), the ECN display alternatives, or to
provide orders to Nasdaq voluntarily shall:
    (1) Demonstrate to Nasdaq that it is in compliance with Regulation
ATS or that it qualifies as an ECN meeting the definition in the SEC
Rule 600;
    (2) Be registered as a Nasdaq member;
    (3) Enter into and comply with the terms of applicable agreements
with Nasdaq;

    (4) Agree to provide for Nasdaq's dissemination in the quotation
data made available to quotation vendors the prices and sizes of
[Nasdaq market maker orders (and orders from other] subscriber[s]
orders of the ATS or ECN, if the ATS or ECN so chooses or is required
by SEC Rule 301(b)(3) to display a subscriber's order in Nasdaq[)], at
the highest buy price and the lowest sell price for each Nasdaq
security entered in and widely disseminated by the ATS or ECN; and
prior to entering such prices and sizes, register with Nasdaq Market
Operations as an ATS or ECN;
    (5) Provide an automatic[ ed] execution [or, if the price is no
longer available, an automated rejection] of any quote or order [routed
to] entered into the System by the ATS or ECNJ through the Nasdaq-
provided display alternative.]
    [(6) Not charge to broker-dealers that access the ATS or ECN
through the Nasdaq Market Center any fee that is inconsistent with the
requirements of SEC Rule 301(b)(4) or that exceeds $0.003 per share].
    [(c) When a Nasdaq member attempts to electronically access through
a Nasdaq-provided system an ATS or ECN-displayed order by sending an
order that is larger than the ATS's or ECN's Nasdaq-displayed size and
the ATS or ECN is displaying the order in Nasdaq on a reserved size
basis, the Nasdaq member that operates the ATS or ECN shall execute
such Nasdaq-delivered order:]
    [(1) Up to the size of the Nasdaq-delivered order, if the ATS or
ECN order (including the reserved size and displayed portions) is the
same size or larger than the Nasdaq-delivered order; or]
    [(2) Up to the size of the ATS or ECN order (including the reserved
size and displayed portions), if the Nasdaq-delivered order is the same
size or larger than the ATS or ECN order (including the reserved size
and displayed portions).]
    [No ATS or ECN operating in Nasdaq pursuant to this rule is
permitted to provide a reserved-size function unless the size of the
order displayed in Nasdaq is 100 shares or greater. For purposes of
this rule, the term ``reserved size'' shall mean that a customer
entering an order into an ATS or ECN has authorized the ATS or ECN to
display publicly part of the full size of the customer's order with the
remainder held in reserve on an undisplayed basis to be displayed in
whole or in part as the displayed part is executed.]
    [Nothing in this Rule shall require the provision to Nasdaq of a
locking or crossing bid or offer, if such locking or crossing bid or
offer is instead provided to another display alternative operated by a
national securities exchange or national securities association.]

4624. Penalty Bids and Syndicate Covering Transactions

    (a) A Nasdaq Market Maker [or ITS/CAES Market Maker] acting as a
manager (or in a similar capacity) of a distribution of a security that
is a subject or reference security under SEC Rule 101 shall provide
written notice to the Corporate Financing Department of NASD
Regulation, Inc. of its intention to impose a penalty bid on syndicate
members or to conduct syndicate covering transactions pursuant to SEC
Rule 104 prior to imposing the penalty bid or engaging in the first
syndicate covering transaction. A Nasdaq Market Maker [or ITS/CAES
Market Maker] that intends to impose a penalty bid on syndicate members
may request that its quotation be identified as a penalty bid on Nasdaq
pursuant to paragraph (c) below.
    (b) The notice required by paragraph (a) shall include:
    (1) The identity of the security and its symbol;
    (2) The date the member is intending to impose the penalty bid and/
or conduct syndicate covering transactions.
    (c) Notwithstanding paragraph (a), a Nasdaq Market Maker [or ITS/
CAES Market Maker] may request that its quotation be identified as a
penalty bid on Nasdaq display by providing notice to Nasdaq
MarketWatch, which notice shall include the date and time that the
penalty bid identifier should be entered on Nasdaq and, if not in
writing, shall be confirmed in writing no later than the close of
business the day the penalty bid identifier is entered on Nasdaq.
    (d) The written notice required by this Rule may be submitted on
the Underwriting Activity Report.

4625. Obligation To Provide Information

    (a) A Nasdaq Market Maker, Nasdaq ECN, or Order Entry Firm [or ITS/
CAES Market Maker] operating in or participating in the Nasdaq Market
Center or other Nasdaq-operated system shall provide information
orally, in writing, or electronically (if such information is, or is
required to be, maintained in electronic form) to the staff of Nasdaq
when:
    (1) Nasdaq MarketWatch staff makes an oral, written, or
electronically communicated request for information relating to a
specific Nasdaq rule, SEC rule, or provision of a joint industry plan
(e.g., ITS, UTP, CTA, and CQA) (as promulgated and amended from time-
to-time) that Nasdaq MarketWatch is responsible for administering or to
other duties and/or obligations imposed on Nasdaq MarketWatch by
Nasdaq; this shall include, but not be limited to, information relating
to:
    (A) A locked or crossed market; or
    (B) Reserved
    (C) Trading activity, rumors, or information that a member may
possess that may assist in determining whether there is a basis to
initiate a trading halt, pursuant to Nasdaq Rule 4120 and IM-4120-1; or
    (D) A quotation that appears not to be reasonably related to the
prevailing market; or
    (E) A clearly erroneous transaction, pursuant to Nasdaq Rule 11890;
or
    (F) A request for an excused withdrawal or reinstatement, pursuant
to Nasdaq Rules 4619[,] and 4620[, and 5222]; or
    (G) The resolution of a trade-through complaint, or other
transaction, pursuant to Nasdaq Rules 4759 [, 5262, 5265,] and 11890;
or
    (H) A request to submit a stabilizing bid, pursuant to Nasdaq Rule
4614, or a request to have a quotation identified as a penalty bid on
Nasdaq, pursuant to Nasdaq Rule 4624.
    (2) Nasdaq Market Operations staff makes an oral, written, or
electronically communicated request for information relating to a
specific Nasdaq rule, SEC rule, provision of a joint industry plan
(e.g., ITS, UTP, CTA, and CQA) (as promulgated and amended from time-
to- time) that Nasdaq Market Operations is responsible for
administering or to other duties and/or obligations for which Nasdaq
Market Operations is responsible, this shall include, but not be
limited to, information relating to an equipment failure.
    (b) A failure to comply in a timely, truthful, and/or complete
manner with a request for information made pursuant to this rule may be
deemed conduct inconsistent with just and equitable principles of
trade.

4626. Limitation of Liability

    (a) Except as provided for in paragraph (b) below, Nasdaq and its
affiliates shall not be liable for any losses, damages, or other claims
arising out of the Nasdaq Market Center or its use. Any losses,
damages, or other claims, related to a failure of the Nasdaq Market
Center to deliver, display, transmit, execute, compare, submit for
clearance and settlement, adjust, retain priority for, or otherwise
correctly process an order, Quote/Order, message, or other data entered
into, or created by,

the Nasdaq Market Center shall be absorbed by the member, or the member
sponsoring the customer, that entered the order, Quote/Order, message,
or other data into the Nasdaq Market Center.
    (b) Nasdaq, subject to the express limits set forth below, may
compensate users of the Nasdaq Market Center or Nasdaq's Brut [order
execution] system for losses directly resulting from the systems'
actual failure to correctly process an order, Quote/Order, message, or
other data, provided the Nasdaq Market Center, or Brut system, as
applicable, has acknowledged receipt of the order, Quote/Order,
message, or data.
    (1) For one or more claims made by a single market participant
related to the use of the Nasdaq Market Center or Brut system on a
single trading day, Nasdaq's liability shall not exceed the larger of
$100,000, or the amount of any recovery obtained by Nasdaq under any
applicable insurance policy.

single calendar month, Nasdaq's liability shall not exceed the larger
of $500,000, or the amount of the recovery obtained by Nasdaq under any
applicable insurance policy.
    (4) In the event all of the claims arising out of the use of the
Nasdaq Market Center or Brut system cannot be fully satisfied because
in the aggregate they exceed the maximum amount of liability provided
for in this Rule, then the maximum amount will be proportionally
allocated among all such claims arising on a single trading day, or
during a single calendar month, as applicable.
    (5) All claims for compensation pursuant to this Rule shall be in
writing and must be submitted no later than the opening of trading on
the next business day following the day on which the use of the Nasdaq
Market Center or the Brut system gave rise to such claims. Nothing in
this rule shall obligate Nasdaq or Brut to seek recovery under any
applicable insurance policy.

4627. Obligation To Honor System Trades

    (a) If a Participant, or clearing member acting on a Participant's
behalf, is reported by the System, or shown by the activity reports
generated by the System, as constituting a side of a System trade, such
Participant, or clearing member acting on its behalf, shall honor such
trade on the scheduled settlement date.
    (b) Nasdaq shall have no liability if a Participant, or a clearing
member acting on the Participant's behalf, fails to satisfy the
obligations in paragraph (a).

under paragraphs (a)(2) of Rule 4611 shall be notified when Nasdaq
exercises it authority under paragraph (b)(1) above.
    (3) The authority and procedures contained in this paragraph (b) do
not otherwise limit Nasdaq's authority, contained in other provisions
of the Nasdaq Rules, to enforce its rules or impose any fitting
sanction.

    (1) ``Attributable Orders,'' orders that are designated for display
(price and size) next to the Participant's MPID;
    (2) ''Non-Attributable Orders,'' orders that are entered by a
Participant that is designated for display (price and size) on an
anonymous basis in the order display service of the System; and
    (3) ``Non-Displayed Orders,'' a limit order that is not displayed
in the System, but nevertheless remains available for potential
execution against all incoming orders until executed in full or
cancelled.
    (f) The term ``Order Type'' shall mean the unique processing
prescribed for designated orders that are eligible for entry into the
System, and shall include:
    (1) ``Discretionary Orders'' are orders that have a displayed price
and size, as well as a non-displayed discretionary price range, at
which the entering party, if necessary, is also willing to buy or sell.
The non-displayed trading interest is not entered into the System book
ut is, along with the displayed size, converted to an IOC buy (sell)
order priced at the highest (lowest) price in the discretionary price
range when displayed shares become available or an execution takes
place at any price within the discretionary price range. The generation
of this IOC order is triggered by the cancellation of the open shares
of the Discretionary Order. If more than one Discretionary Order is
available for conversion to an IOC order, the system will convert all
such orders at the same time and priority will be given to the first
IOC order(s) that reaches the trading interest on the other side of the
market. If an IOC order is not executed in full, the unexecuted portion
of the order is automatically re-posted and displayed in the System
book with a new time stamp, at its original displayed price, and with
its non-displayed discretionary price range.
    (2) ``Reserve Orders'' are limit orders that have both a round-lot
displayed size as well as an additional non-displayed share amount.
Both the displayed and non-displayed portions of the Reserve Order are
available for potential execution against incoming orders. If the
round-lot displayed portion of a Reserve Order is reduced to less than
a normal unit of trading, the System will replenish the display portion
from reserve up to at least a single round-lot amount. A new timestamp
is created for the replenished portion of the order each time it is
replenished from reserve, while the reserve portion retains the time-
stamp of its original entry.
    (3) ``Limit Orders'' are orders to buy or sell a stock at a
specified price or better. A limit order is marketable when, for a
limit order to buy, at the time it is entered into the System, the
order is priced at the current inside offer or higher, or for a limit
order to sell, at the time it is entered into the System, the order is
priced at the inside bid or lower.
    (4) ``Pegged Orders'' are orders that, after entry, has their price
automatically adjusted by the System in response to changes in bids or
offers in the market, as appropriate. A Pegged Order can specify that
its price will equal the inside quote on the same side of the market
(``Primary Peg'') or the opposite side of the market (``Market Peg'').
A Pegged Order may have a limit price beyond which the order shall not
be executed. In addition, Pegged Orders may also establish their
pricing relative to the appropriate bids or offers by the selection of
one or more offset amounts that will adjust the price of the order by
the offset amount selected. A new timestamp is created for the order
each time it is automatically adjusted.
    (5) ``Minimum Quantity Orders'' are orders that require that a
specified minimum quantity of shares be obtained, or the order is
cancelled. Minimum Quantity Orders may only be entered with a time-in-
force designation of System Hours Immediate or Cancel or Market Hours
Immediate or Cancel. Minimum Quantity Orders with a Market Hours
Immediate or Cancel time in force received prior to the opening cross
or after 4 p.m. will be rejected.
    (6) ``Intermarket Sweep Order'' or ``ISO'' are limit orders that
are designated as ISOs in the manner prescribed by Nasdaq and are
executed within the System by Participants at multiple price levels
without respect to Protected Quotations of other market centers within
the meaning of Rule 600(b) of Regulation NMS under the Exchange Act of
1934. ISOs are immediately executable within the System pursuant to
Rule 4757 and shall not be eligible for routing as set out in Rule
4758.
    Simultaneously with the routing of an ISO to the System, one or
more additional limit orders, as necessary, are routed by the entering
party to execute against the full displayed size of any protected bid
or offer (as defined in Rule 600(b) of Regulation NMS under the Act) in
the case of a limit order to sell or buy with a price that is superior
to the limit price of the limit order identified as an intermarket
sweep order (as defined in Rule 600(b) of Regulation NMS under the
Act). These additional routed orders must be identified as intermarket
sweep orders.
    (7) ``Price to Comply Order'' are orders that, if, at the time of
entry, a Price to Comply Order would create a violation of Rule 610(d)
of Regulation NMS under the Exchange Act of 1934 by locking or crossing
the protected quote of an external market or would cause an Order
Protection Rule violation, the order will be converted by the System to
a Non-Displayed Order and re-priced to the current low offer (for bids)
or to the current best bid (for offers). Such Non-Displayed Orders will
be cancelled by the System if the market moves through the price of the
order after the order is accepted.
    (8) ``Price to Comply Post Order'' are orders that, if, at the time
of entry, a Price to Comply Post Order would create a violation of Rule
610(d) of Regulation NMS under the Exchange Act of 1934 by locking or
crossing the protected quote of an external market or would cause an
Order Protection Rule violation, the order will be re-priced and
displayed by the System to one MPV below the current low offer (for
bids) or to one penny above the current best bid (for offers). Price to
Comply Post Orders will not be routed outside of the System.
    (g) The term ``Order Size'' shall mean the number of shares up to
999,999 associated with a Quote or Order and shall include:
    (1) ``Normal unit of trading'': The round lot size for the

disseminate by electronic means an Order Imbalance Indicator every 5
seconds until market close.
    (2)(A) The Nasdaq Closing Cross will occur at the price that
maximizes the number of shares of Eligible Interest in the Nasdaq
Market Center to be executed.
    (B) If more than one price exists under subparagraph (A), the

Closing Cross.
    (E) If the Nasdaq Closing Cross Price established by subparagraphs
(A) through (D) above is outside the benchmarks established by Nasdaq
by a threshold amount, the Nasdaq Closing Cross will occur at a price
within the threshold amounts that best satisfies the conditions of
subparagraphs (A) through (D) above. Nasdaq management shall set and
modify such benchmarks and thresholds from time to time upon prior
notice to market participants.
    (3) If the Nasdaq Closing Cross price is selected and fewer than

4755. Order Entry Parameters

    ( a) System Orders
    (1) General--A System order is an order that is entered into the
System for display and/or execution as appropriate. Such orders are
executable against marketable contra-side orders in the System.
    (A) All System Orders shall indicate limit price and whether they
are a buy, short sale, short-sale exempt, or long sale. Systems Orders
can be designated as Market Hours Immediate or Cancel (``MIOC''),
Market Hours Good-till-Cancelled (``MGTC''), Market Hours Day
(``MDAY''), System Hours Expire Time (``SHEX''), System Hours Day
(``SDAY''), System Hours Immediate or Cancel (``SIOC''), System Hours

Intermarket Sweep Order, a Price to Comply Order, a Price to Comply
Post Order, or a Discretionary Order.
    (C) System Hours Pegged Orders. excluding System Hours Pegged
Orders ultimately sought to be directed to either the New York Stock
Exchange (``NYSE'') or the American Stock Exchange (``AMEX''), may only
be entered between 9:30 a.m. and 4:00 p.m. eastern time.
    (2) Short Sale Compliance--System orders to sell short shall not be
executed if the execution of such an order would violate any applicable
short sale regulation of the SEC or Nasdaq.
    (3) Routing--All System orders entered by Participants directing or
permitting routing to other market centers shall be routed for
potential display and/or execution as set forth in Rule 4758 in
Compliance with Regulation NMS.

    (4) Regulation NMS--Intermarket Sweep Orders shall be executed
exclusively within the System and the entering Participants shall be
responsible for compliance with Regulation NMS Order Protection Rule
and Locked and Crossed market rule with respect to such orders. Orders
eligible for execution outside the System shall be processed in
compliance with Regulation NMS, including accessing protected
quotations and resolving locked and crossed markets, as instructed.

4756. Entry and Display of Quotes and Orders

    (a) Entry of Orders--Participants can enter orders into the System,
subject to the following requirements and conditions:
    (1) Participants shall be permitted to transmit to the System
multiple orders at a single as well as multiple price levels. Each
order shall indicate the amount of Reserve Size (if applicable).
    (2) The System shall time-stamp an order which shall determine the
time ranking of the order for purposes of processing the order.
    (3) Orders can be entered into the System (or previously entered
orders cancelled) from 7 a.m. until 8 p.m. eastern time.
    (b) Entry of Quotes--Nasdaq Market Makers and Nasdaq ECNs can enter
Quotes into the system from 7 a.m. to 8 p.m. eastern time. When open,
Quotes will be processed as System Hours GTC Orders (SGTC). Nasdaq
Market Makers and Nasdaq ECNs may elect to utilize the Automatic Quote
Refresh functionality. Entry of Quotes will be subject to the
requirements and conditions set forth in section (a) above.
    (c) Display of Quotes and Orders--The System will display quotes
and orders submitted to the System as follows:
    (1) System Book Feed--Quotes and orders resident in the System
available for execution will be displayed via the System Book Feed.
    (2) Best Priced Order Display--For each System Security, the
aggregate size of all Quotes and Orders at the best price to buy and
sell resident in the System will be transmitted for display to the
appropriate network processor, unless the aggregate size is less than
one round lot in which case the aggregate size will be displayed in the
System Book Feed but not be transmitted to a network processor.
    (3) Exceptions-- The following exceptions shall apply to the
display parameters set forth in paragraphs (1 ) and (2) above:
    (A) Reserve Size--Reserve Size shall not be displayed in the
System, but shall be accessible as described in Rule 4757.
    (B) Discretionary Orders--The discretionary portion of
Discretionary Orders shall not be displayed but shall be made available
for execution only upon the appearance of contra-side marketable
trading interest, and shall be executed pursuant to 4751(f) and Rule
4757.
    (C) Non-Displayed Orders--Non-Displayed Orders are not displayed in
the System, and have lower priority within the System than an equally
priced Displayed Order, regardless of time stamp, and shall be executed
pursuant to Rule 4757.
    (D) ITS Trade-Through Compliance and Locked or Crossed Markets--If,
at the time of entry, a Displayed Order in an exchange-listed security
that the entering party has elected not to make eligible for routing
would lock or cross the market, it will be converted by the System into
a Non-Displayed Order. If, at the time of entry, a Displayed Order
would lock or cross the market or would cause a trade-through
violation, the order will be converted by the System to a Non-Displayed
Order and re-priced to the current low offer (for bids) or to the
current best bid (for offers). Such Non-Displayed Orders will be
cancelled by the System if the market moves through the price of the
order after the order is accepted. For securities subject to the SEC's
De Minimis Exemption for certain Exchange Traded Funds, if, at the time
of entry, a Displayed Order that the entering party has elected not to
make eligible for routing would lock or cross the market, it will be
converted by the System into a Non-Displayed Order. If, at the time of
entry, a Displayed Order would cross the market by more than 3 cents or
would cause a trade-through violation, the order will be converted by
the System to a Non-Displayed Order and re-priced to 3 cents above the
current low offer (for bids) or 3 cents below the current best bid (for
offers). Such Non-Displayed Orders will be cancelled by the System if
the market moves through the price of the order after the order is
accepted.
    (4) Pursuant to Rule 600(b)(4) of Regulation NMS under the Act,
Nasdaq has implemented such systems, procedures, and rules as are
necessary to render it capable of meeting the requirements for
automated quotations, as defined in Rule 600(b)(3) of Regulation NMS
under the Act; and immediately to identify its quotations as manual
whenever it has reason to believe it is not capable of displaying
automated quotations. Nasdaq has adopted policies and procedures for
notifying members and other trading centers that it has reason to
believe it is not capable of displaying automated quotations or, once
manual, that it has restored the ability to display automated
quotations and is preparing to identify its quotation as automated. In
addition, Nasdaq has adopted policies and procedures for responding to
notices that it receives from other trading centers indicating that
they have elected to use the ``self-help'' exception of Rule 611(b)(1)
of Regulation NMS under the Act.

4757. Book Processing

    (a) System orders shall be executed through the Nasdaq Book Process
set forth below:
    (1) Execution Algorithm-Price/Time--The System shall execute
equally priced or better priced trading interest within the System in
price/time priority in the following order:
    (A) Displayed Orders;
    (B) Non-Displayed Orders, the reserve portion of Quotes and Reserve
Orders, in price/time priority among such interest;
    (C) The discretionary portion of Discretionary Orders as set forth
in Rule 4751(f).
    (2) Decrementation--Upon execution, an order shall be reduced by an
amount equal to the size of that execution.
    (3) Price Improvement--any potential price improvement resulting
from an execution in the System shall accrue to the taker of liquidity.
    Example:
    Buy order resides on System book at 10.
    Incoming order to sell priced at 9 comes into the System.
    Order executes at 10 (seller get $1 price improvement).

4758. Order Routing

    (a) Order Routing Process
    (1) The Order Routing Process shall be available to Participants
from 7 a.m. until 8 p.m. Eastern Time, and shall route orders as
described below:
    (A) Exchange-Listed Routing Options. The System provides four
routing options for orders in exchange-listed securities. Of these
four, only DOT is available for orders ultimately sought to be directed
to either the New York Stock Exchange (''NYSE'') or the American Stock
Exchange (``AMEX''). The System also allows firms to send individual
orders to the NYSE Direct + System, and to elect to have orders not be
sent to the AMEX. Except as noted below in SPDY, routed pegged orders
in securities listed on another exchange, the System will consider the
quotations of accessible markets. The four System routing

options for NYSE and/or Amex listed orders are:
    (i) DOT (``DOT'')--under this option, after checking the System for
available shares, orders are sent to other available market centers for
potential execution, per entering firm's instructions before the
destination exchange, so long as such price would not violate the Order
Protection Rule. Any un-executed portion will thereafter be sent to the
NYSE or AMEX, as appropriate, at the order's original limit order price
as a non-intermarket sweep order (ISO). This option may only be used
for orders with time-in-force parameters of either SDAY, SIOC, MDAY,
MIOC, GTMC or market-on-open/close.
    (ii) Reactive Electronic Only (``STGY'')--under this option, after
checking the System for available shares, orders are sent to other
available market centers for potential execution, per entering firm's
instructions, in compliance with the Order Protection Rule. When
checking the book, the System will seek to execute at the price it
would send the order to a destination market center. If shares remain
un-executed after routing, they are posted on the book and are not sent
to the NYSE or AMEX. Once on the book, should the order subsequently be
locked or crossed by another accessible market center, the System shall
route the order to the locking or crossing market center for potential
execution in order to resolve the locked or crossed market. With the
exception of the Minimum Quantity order type, all time-in-force
parameters and order types may be used in conjunction with this routing
option. This process is one of the routing strategies allowed by the
System for all securities.
    (iii) Electronic Only Scan (``SCAN'')--under this option, after
checking the System for available shares, orders are sent to other
available market centers for potential execution, per entering firm's
instructions, in compliance with Rule 6111 under Regulation NMS. When
checking the book, the System will seek to execute at the price it
would send the order to a destination market center. If shares remain
un-executed after routing, they are posted on the book and are not sent
to the NYSE or AMEX. Once on the book, should the order subsequently be
locked or crossed by another market center, the System will not route
the order to the locking or crossing market center. With the exception
of the Minimum Quantity order type, all time-in-force parameters and
order types may be used in conjunction with this routing option. This
process is one of the routing strategies allowed by the System for all
securities.
    (iv) Aggressive Electronic Only (``SPDY'')--under this option,
after checking the System for available shares, orders are sent to
other available market centers for potential execution, per entering
firm's instructions, in compliance with Rule 611 of Regulation NMS.
When checking the book, the System will seek to execute at the price it
would send the order to a destination market center. If shares remain
un-executed after routing, they are posted on the book and are not sent
to the NYSE or AMEX. Once on the book, should the order subsequently be
locked or crossed by another accessible market center, the System shall
route the order to the locking or crossing market center for potential
execution in order to resolve the locked or crossed market. Market
orders with the SPDY designation will, during a locked or crossed
market, have their price adjusted by the System to match the best price
displayed on the same side of the market as the market order (i.e., a
buy order to the bid, a sell to the offer). If the order is for a
security eligible for a de minimis exception to the trade-through rule
set forth in Section 8(d)(i) of the ITS Plan, the System will ignore
AMEX prices when adjusting the SPDY order during a locked or crossed
market. With the exception of the Minimum Quantity order type, all
time-in-force parameters and order types may be used in conjunction
with this routing option. The process is one of the routing strategies
allowed by the System for all securities.
    (B) Nasdaq-Listed Routing Options. The STGY, SPDY, and SCAN options
are the only routing options provided by the System for orders in
Nasdaq-listed securities not sought to be directed to either the NYSE
or AMEX. For routed pegged orders in Nasdaq-listed securities, the
System will consider accessible, automated quotes.
    (C) Priority of Routed Orders. Regardless of the routing option
selected, orders sent by the System to other markets do not retain time
priority with respect to other orders in the System and the System
shall continue to execute other orders while routed orders are away at
another market center. Once routed by the System, an order becomes
subject to the rules and procedures of the destination market
including, but not limited to, short-sale regulation and order
cancellation. If a routed order is subsequently returned, in whole or
in part, that order, or its remainder, shall receive a new time stamp
reflecting the time of its return to the System.

4759. ITS Commitments

    Until such time as Nasdaq withdraws from the ITS Plan, Quotes and
Orders that are eligible for ITS will be processed by the System and
routed to the appropriate Non-Nasdaq Participant Market as an ITS
Commitment in accordance with the requirements of the ITS Plan and all
applicable Nasdaq rules. Nasdaq shall participate in the ITS Plan as
set forth below.
    (a) Incorporation of ITS Rules.
    (1) Pre Opening Application. Nasdaq may use the System to
participate in the Pre Opening Application in accordance with Section 7
and Exhibit A of the ITS Plan as though they were set forth in their
entirety herein.
    (2) The System will comply with the Order Protection obligations
set forth in Section 8(d) and Exhibits B and C of the ITS Plan as
though they were set forth herein in their entirety.
    (b) Inbound ITS Commitments
    (1) If the ITS Commitment contains an obvious error, the Nasdaq
Market Center will decline it. For purposes of this Rule, a transaction
may have an obvious error in any term, such as price, number of shares
or other unit of trading, identification of the security, or if a
specific commitment to trade has been executed with the wrong Nasdaq
Market Maker.
    (2) If the ITS Commitment, if executed, would result in a violation
of SEC Rule 10a-1, the Nasdaq Market Center will decline it.
    (3) If the conditions described in subparagraphs (1) and (2) above
do not apply, the System will execute an inbound ITS Commitment in
accordance with applicable provisions of the ITS Plan.
    (c) Outbound Commitments: Any ``commitment to trade,'' which is
transmitted by an Nasdaq Participant to another Non-Nasdaq ITS
Participant Market through ITS, shall be firm and irrevocable for the
period of thirty seconds following transmission by the sender. All such
commitments to trade shall, at a minimum:
    (1) Direct the commitment to a particular Non-Nasdaq Participant
Market;
    (2) Specify the security which is the subject of the commitment;
    (3) Designate the commitment as either a commitment to buy or a
commitment to sell;
    (4) Specify the amount of the security to be bought or sold, which
amount shall be for one unit of trading or any multiple thereof;
    (5) Specify:
    (A) A price equal to the offer or bid price then being furnished by
the

destination Non-Nasdaq Participant Market, which price shall represent
the price at or below which the security is to be bought or the price
at or above which the security is to be sold, respectively;
    (B) A price at the execution price in the case of a commitment to
trade sent in compliance with the block trade rule; or
    (C) That the commitment is a commitment to trade ``at the market'';
    (6) Designate the commitment ``short'' or ``short exempt'' whenever
it is a commitment to sell which, if it should result in an execution
in the receiving market, would result in a short sale to which the
provisions of SEC Rule 10a-1(a) under the Act would apply.
    (d) Transactions in ITS securities executed in the System are
reported to the CTA Plan Processor by the System at the price specified
in the commitment or if executed at a better price, the execution
price.

IM 4759-1. Contemporaneous Sending of ITS Commitments

    With respect to trading of ITS Securities only, the terms ``trade-
through'' and ``third participating market center trade-through'' do
not include the situation where a member who initiates the purchase (
sale) of an ITS Security, at a price which is higher (lower) than the
price at which the security is being offered (bid) in another ITS
Participant Market, sends contemporaneously through ITS to such ITS
Participant Market a commitment to trade at such offer (bid) price or
better and for at least the number of shares displayed with that market
center's better-priced offer (bid). A trade-through complaint sent in
these circumstances is not valid, even if the commitment sent in
satisfaction cancels or expires, and even if there is more stock behind
the quote in the other market.

4760. Anonymity

    (a) Transactions executed in the System shall be cleared and
settled anonymously. The transaction reports produced by the System
will indicate the details of the transactions, and shall not reveal
contra party identities.
    (b) Nasdaq shall reveal a Participant's identity in the following
circumstances:
    (1) When a registered clearing agency ceases to act for a
participant. or the Participant's, clearing firm, and the registered
clearing agency determines not to guarantee the settlement of the
Participant's trades;
    (2) For regulatory purposes or to comply with an order of an
arbitrator or court;
    (3) If both Participants to the transaction consent;
    (4) Unless otherwise instructed by a member, Nasdaq will reveal to
a member, no later than the end of the day on the date an anonymous
trade was executed, when the member's Quote or Order has been
decremented by another Quote or Order submitted by that same member.

4761. Adjustment of Open Quotes and/or Orders

    The Nasdaq Market Center will automatically purge all open quotes
and/or orders in all Nasdaq Market Center eligible securities resident
in the system in response to issuer corporate actions related to a
dividend, payment or distribution, on the ex-date of such actions,
except where a cash dividend or distribution is less than one cent
($0.01).

4762. Clearly Erroneous Transactions

    All matters related to clearly erroneous transactions executed in
the System shall be initiated and adjudicated pursuant to Rule 11890.

A. Self-Regulatory Organization's Statement of the Purpose of, and
Statutory Basis for, the Proposed Rule Change

1. Purpose
    Nasdaq currently operates three execution systems: (1) The Nasdaq
Market Center, formerly known as Supermontage (``NMC Facility''); (2)
the Brut ECN, a registered broker-dealer which is a Nasdaq subsidiary
(``Brut Facility''); and (3) the INET ECN which is also operated by
Brut, LLC, a subsidiary of Nasdaq (``INET Facility'') (collectively,
the ``Nasdaq Facilities'').\6\ The Nasdaq Facilities are all linked,
but each operates pursuant to independent Commission-approved rules,
the NMC Facility under the 4700 Series, the Brut Facility under the
4900 Series, and the INET Facility under the 4950 Series.
---------------------------------------------------------------------------

    \6\ Nasdaq states that, until January 31, 2006, INET ATS, Inc.
was a registered broker-dealer and a member of the NASD. On February
1, 2006, the INET broker-dealer was merged into the Brut broker-
dealer which is a member of the New York Stock Exchange. Nasdaq
states that it will continue to operate the Brut Facility and INET
Facility under the rubric of a single broker-dealer until the
Integrated System is fully operational.
---------------------------------------------------------------------------

    Through this filing, Nasdaq is proposing to integrate the three
matching systems operating in the Nasdaq Facilities into a single
matching system (the ``Integrated System'' or ``System''), governed by
a single set of rules, and subject to a single fee schedule. Nasdaq
states that, to ease the transition for Nasdaq participants, the
Integrated System will utilize the same connectivity by which users
access each of the Nasdaq Facilities, and leverage functionality that
is already approved and operational within one or more of the Nasdaq
Facilities. For example, the Integrated System will use slightly
modified functionality from the INET Facility for order entry, display,
processing, and routing and draw on functionality in the NMC Facility
for the opening and closing processes. Participants will remain subject
to general obligations applicable to all Nasdaq Facilities, including
honoring System trades, complying with all Commission and Nasdaq rules,
and properly clearing and settling trades.
    As described in more detail below, Nasdaq is also proposing limited
modifications that are: (1) Designed to ensure Nasdaq's compliance with
Regulation NMS; (2) utilized when Nasdaq operates as an exchange; and
(3) improvements to how the System serves investors, for example, by
requiring participation in the System on an automated basis.
    1. Reorganization and Simplification of Rules. Nasdaq states that
merging the three Nasdaq Facilities into a single platform provides
Nasdaq with an opportunity to simplify its rule manual and make it more
transparent to investors. Nasdaq will merge five sets of rules (the
4600, 4700, 4900, 4950, and 5200 Series) into two (the 4600 and 4750
Series). First, Nasdaq is proposing to eliminate two complete sets of
rules, those governing the Brut Facility (4900 Series) and those
governing the INET Facility (4950 Series). Because the Integrated
System draws from both the current NMC Facility rules as well as

the INET Facility rules, Nasdaq determined to create an entirely new
set of rules for the Integrated System, the 4750 Series, rather than
attempt to modify the current NMC Facility rules.
    Second, since the Integrated System provides a single platform for
the trading of stocks listed on the Nasdaq exchange as well as other
exchanges, Nasdaq is merging the rules governing members that trade
both sets of securities. Specifically, Nasdaq is proposing to eliminate
the Nasdaq Rule 5200 Series governing securities eligible to trade via
the Intermarket Trading System (``ITS Securities''). Nasdaq will retain
the obligations set forth in the Nasdaq Rule 5200 Series, many of which
overlap completely with rules in the Nasdaq Rule 4600 Series that
currently apply only to market makers in Nasdaq-listed securities.
Nasdaq will insert into similar rules already contained in the Nasdaq
Rule 4600 Series governing Nasdaq-listed securities. As a result, the
proposed Nasdaq Rule 4600 Series will set forth the obligations of all
Nasdaq participants--market makers, order entry firms, and ECNs--in all
securities traded on Nasdaq.
    Nasdaq states that, because market makers in ITS Securities are
already subject to strict regulations applicable to those for Nasdaq
securities, Nasdaq is able to merge these rule sets with the assistance
of only a single new rule. Proposed Nasdaq Rule 4602 sets forth
definitions formerly contained in Nasdaq Rule 5210 that are specific to
the trading of ITS Securities. All other market maker obligations from
the Nasdaq Rule 5200 Series will reside in the Nasdaq Rule 4600 Series
with minor changes or none at all. Specifically, Nasdaq is proposing to
merge former Nasdaq Rule 5220 regarding ITS/CAES Registration into
proposed Nasdaq Rule 4611; former Nasdaq Rule 5221 (Obligations of ITS/
CAES Market Makers) into proposed Nasdaq Rules 4612 and 4613; former
Nasdaq Rule 5222 (Withdrawal of Quotations) into proposed Nasdaq Rule
4619; former Nasdaq Rule 5223 (Voluntary Termination of Registration)
into proposed Nasdaq Rule 4620; former Nasdaq Rule 5224 (Suspension and
Termination of Quotations) into proposed Nasdaq Rule 4621; former
Nasdaq Rule 5265 (Authority to Cancel or Adjust Transactions) into
proposed Nasdaq Rule 4762); and former Nasdaq Rule 5266 (Market
Participant Identifiers) into proposed Nasdaq Rule 4613. As a result,
Nasdaq market makers will have virtually uniform obligations across all
securities under those rules. As described in more detail in Section 2
below, the remainder of the Nasdaq Rule 5200 Series obligations will be
retained in proposed Nasdaq Rule 4959 governing ITS Commitments.
