Institutional Subscribers may elect to only interact with trading interest of other institutional Subscribers in Confirm mode. Institutional Subscribers that make such an election will not interact with ILLC's trading interest, including orders submitted via an ILLC algorithm (that is, the ATS views orders submitted via an ILLC algorithm as being submitted by ILLC and not by the underlying customer). Institutional Subscribers may request that ILLC identify trading interest submitted via ILLC algorithms as representing trading interest of an underlying "institutional" Subscriber. Institutional Subscribers that wish to opt-out of interacting with broker-dealer trading interest must contact their ILLC sales representative, who will help implement the request. 

Institutional Subscribers may elect to only interact with trading interest of other institutional Subscribers in Confirm Mode. Subscribers that make such an election will not interact with trading interest of ILLC's broker-dealer affiliates. Institutional Subscribers that wish to opt-out of interacting with broker-dealer trading interest must contact their ILLC sales representative, who will help implement the request. 

As discussed above, only institutional Subscribers may make elections regarding order interaction. 

BACKGROUND: For purposes of this Form ATS-N, Subscribers to the ATS will, where necessary, be termed Direct or Indirect Subscribers. Direct Subscribers are ILLC clients that have been approved to direct their orders to the ATS (i.e., Subscribers who have elected not to utilize the electronic trading products offered by ILLC to route their orders or trading interest to the ATS). Direct Subscribers include both those Subscribers that have directed their orders to the ATS via FIX (See discussion in this Part II, Item 5 under the headings Front End for additional details regarding the Front End) and Subscribers who have elected to utilize the blotter integration functionality (See Part III, Item 5) of the Front End to submit orders and trading interest to the ATS.

Indirect Subscribers are ILLC clients that have been approved to use one or more of the Instinet order and execution management systems ("Instinet OMSs"), the Instinet Execution suite of algorithms ("Instinet Algorithms"), or the Instinet Smart Order Router ("SOR"), all of which may route Indirect Subscriber orders to the ATS based on routing determinations made by the relevant product. Direct and Indirect Subscribers are collectively referred to as "Subscribers." Clients may be both Direct and Indirect Subscribers, depending on the method the Subscriber used to access the ATS.

The use of the Instinet Algorithms and SOR services to enter orders into the ATS is discussed in Part III, Item 5(a). Additionally, ILLC offers its clients order routing and execution support services through the component groups of ILLC's trading desk listed in Part II, Item 1. The Instinet Algorithms, SOR, and Instinet OMSs are referred to herein as the "Instinet Trading Products."

Subscribers submit orders to BlockCross via the Front End. Subscribers may submit trading interest to the Front End automatically via blotter integration (See Part III, Item 5) or manually via FIX connection. Subscribers may also manually submit orders to the Front End by using the BlockCross Desktop Application. All trading interest accesses the ATS via the Front End, including orders routed to BlockCross by the Instinet Algorithms and SOR. ILLC offers these products and services to all Subscribers.

Use of these products and services is governed by ILLC's client agreement (the "Client Agreement"), which contain no specific terms and conditions for routing orders into the ATS. Orders entering BlockCross by any of the products or services listed above will be prioritized, matched, and executed in accordance with matching and execution logic outlined in Part III, Item 11.

ILLC PRODUCTS AND SERVICES: SMART ORDER ROUTER: The SOR is a customizable tool that explores liquidity in various market centers. Clients may elect to utilize the standard SOR configuration to access various market centers (ILLC determines the venues and the order in which client order flow is routed). Clients may also elect to customize the SOR in which case the client may choose the specific venue(s) to which their order flow is routed (to the extent permitted by regulatory requirements) as well as select the sequence in which their order flow is routed to each venue. The SOR will include the ATS as a potential venue, provided the client has not elected to limit its strategy to exclude the ATS. Subscribers may also customize the SOR to access only the ATS. Users of the SOR must be on-boarded as ILLC clients with access to the SOR. Use of the SOR is governed by the Client Agreement, which contains no specific terms and conditions for routing orders into the ATS. Orders routed to the ATS by the SOR will be prioritized, matched, and executed in accordance with the ATS' standard prioritization, matching and execution logic.

INSTINET ALGORITHMS: The Instinet Algorithms include a number of strategies designed to achieve a client's selected trading strategy. Orders routed via the Instinet Algorithms may include the ATS as a possible destination. Clients may customize the operation of the Instinet Algorithms, including limiting the venues accessed (to the extent permitted by regulatory requirements). Trading interest sent to the ATS by an Instinet Algorithm is subject to the ATS' standard prioritization, matching and execution logic. Unless a client has elected otherwise, trading interest entered into to the ATS by an Instinet Algorithm is treated as representing ILLC's trading interest (i.e., broker-dealer agency trading interest) and not the trading interest of the underlying Subscriber. Users of the Instinet Algorithms must be on-boarded as ILLC clients with access to the Instinet Algorithms. Use of the Instinet Algorithms is governed by the Client Agreement, which contains no specific terms and conditions for routing orders into the ATS. Orders entering the ATS through any of the Instinet Algorithms strategies will be prioritized, matched, and executed in accordance with the ATS' standard prioritization, matching and execution logic.

OMS/EMS: ILLC offers the following proprietary order/execution management systems: (1) Newport; (2) Trading Portal; and (3) Tradespeed (collectively, the "Instinet OMSs"). The Instinet OMSs allow users to access the ATS in the following ways: (i) by directing trading interest to the ATS via FIX (such orders are submitted to the ATS via the Front End), (ii) by utilizing an Instinet Algorithm (to the extent offered by the Instinet OMS and permissioned to access the ATS,) and (iii) by otherwise submitting a non-directed order to ILLC for further handling by trading desk personnel or by entering the order in the SOR. Each Instinet OMS allows users to limit accessible trading venues. In the event an order, or a portion of an order, reaches the ATS via an Instinet OMS, the order is subject to the standard prioritization, matching and execution procedures described herein. Users of an Instinet OMS must be on-boarded as ILLC clients with access to an Instinet OMS. Use of the Instinet OMSs is governed by the Client Agreement, which contains no specific terms and conditions for the management of orders ultimately routed to the ATS, and do not differ based on which OMS is utilized.

FRONT END: ILLC owns and operates a front end system (the "Front End"). The Front End is a separate, stand-alone system specific to the BlockCross ATS that includes certain algorithmic and order routing functionality. The Front End allows users to seek contra-side interest for their trading interest outside of BlockCross while simultaneously allowing for matching and execution within BlockCross. Only orders entered into the Front End for possible matching and execution within BlockCross are eligible to access the Front End's algorithmic and order routing functionality. Orders routed from the Front End may include an Instinet ATS other than the BlockCross as a routing destination.

The means by which the order reached the ATS (e.g., Instinet Algorithms, SOR, OMS, FIX) does not affect the order's priority, matching, or execution.

ILLC PRODUCTS AND SERVICES SPECIFIC TO BLOCKCROSS: In addition to the Instinet Trading Products, ILLC offers certain products and services specific to BlockCross.

FRONT END: The Front End is a separate, stand-alone system specific to BlockCross that includes certain messaging and order routing functionality. The Front End allows users to seek contra-side interest for their trading interest in other market centers while simultaneously allowing for matching and execution within BlockCross. Only trading interest registered to the Front End for possible matching and execution within BlockCross is eligible to utilize the Front End's messaging and order routing functionality. Orders routed from the Front End may include other market centers, including an Instinet ATS other than BlockCross, as a routing destination. Users of the Front End must be on-boarded as an ILLC client with access to BlockCross. Use of the Front End is governed by the Client Agreement, which contains no specific terms and conditions for the use of the Front End. Orders entering the ATS by way of the Front End will be prioritized, matched, and will execute in accordance with the matching and execution logic outlined in Part III, Item 11.

DESKTOP APPLICATION: ILLC offers Subscribers the BlockCross Desktop Application (the "Desktop Application") to manually manage orders and trading interest that have been entered on the Front End (e.g. designate orders as committed or uncommitted, select a specific trading mode, or send and receive IOI messages). A user of the Desktop Application must be on-boarded as an ILLC client with access to Desktop Application. Use of the Desktop Application is governed by the Client Agreement, which contains no specific terms and conditions for the use of the Desktop Application. 

BACKGROUND AND SCOPE: Subscribers' confidential trading information includes Subscriber order and execution information and excludes post-execution transaction information of the type made public under reporting rules or regulations, or of an aggregated nature (e.g., aggregated and anonymous order and execution statistics aged at least one day (T+1) from the date of execution) to be Subscriber confidential information.

ILLC utilizes Amazon Web Services, Inc. ("AWS") for cloud computing on the Platform as a Service (PaaS) model for data storage and retention. 

As stated in response to Part II Item 6(a), the Instinet BD Affiliates are wholly owned subsidiaries of IHI and are affiliates of ILLC. The Instinet BD Affiliates may, on behalf of their clients, send orders for execution in U.S. markets to ILLC's trading desks, SOR, and algorithmic trading strategies, many of which include the ATS as a destination. 

BACKGROUND AND SCOPE: ILLC's system comprises an integrated Core Messaging System with numerous applications providing, reading, and consuming data messages from the Core Messaging System. The ATS system (e.g., matching engine and associated applications) and ILLC's systems used to support its agency broker-dealer business run on the Core Messaging System. ILLC maintains policies and procedures designed to safeguard the confidential trading information of Subscribers as well as virtual barriers to prevent unauthorized access to such information.

ILLC's Core Messaging System is the conduit through which all firm-wide order information is processed (e.g., ATS and agency broker-dealer order and execution information). All orders routed to the ATS pass through the Core Messaging System. This information is processed by data messages which are readable only by the applications on the Core Messaging System that have been designed and permissioned by ILLC to do so.

Each application subscribes to different message types and is permissioned to subscribe only to the message types necessary for its designated function. For example, the Instinet Trading Products (Instinet Algorithms, SOR, and OMS/EMS) are subscribed to utilize messages regarding the orders routed by the relevant product, including where orders were routed and/or executed, which may include the ATS or any other market center. The Instinet Trading Products may not access data messages related to other ILLC functions, including data messages related to the ATS generally, Direct Subscriber orders, ATS order priority, or counterparty information.

The BlockCross ATS consists of standalone hardware comprising dedicated servers (collectively the ''BlockCross System'') and software applications separate from the ILLC systems described above.

The connection between the Core Messaging System and the BlockCross System is limited. Instinet Trading Products, housed on the Core Messaging System may access the BlockCross ATS and, by extension, the BlockCross System through FIX connections, similar to any external market center. Additionally, BlockCross order and execution information are periodically copied onto the Core Messaging System, as further discussed below.

EMPLOYEES WITH ACCESS TO SUBSCRIBER CONFIDENTIAL TRADING INFORMATION: Instinet does not have any employees solely responsible for the ATS. The employees described in response to Part II, Item 6(a) have access to Subscriber confidential trading information. These employees are prohibited from sharing any Subscriber confidential trading information with persons not expressly permissioned to receive such information under Instinet policy, as described in Part II, Item 7(a) of this form.

BLOCKCROSS SYSTEMS WITH ACCESS TO DIRECT SUBSCRIBER CONFIDENTIAL TRADING INFORMATION: SUPPORT TOOLS: ILLC maintains support tools (i.e., applications) specific to BlockCross (the ''Support Tools'') designed to allow permissioned employees the ability to view certain types of data necessary to the performance of the employee's job function. Permissioned employees with access to the Support Tools may only access BlockCross data and cannot use the Support Tools to access data from other Instinet ATSs. As discussed below, ILLC grants employees access to the Support Tools necessary to perform their responsibilities and in line with ILLC's Regulation ATS WSPs.

ILLC may permission employees with full access to the Support Tools. Full access allows a permissioned employee to view and manage all data on the BlockCross System, including open orders in the ATS. Permissioned employees will also have the ability to cancel orders in BlockCross. Permissioned employees may also view each order's status (e.g. whether the order has been matched, exposed via the Subscriber IOI functionality, or has been routed out of the ATS via an Instinet Algorithm). Permissioned employees may also edit standing instructions on how the BlockCross System should handle each order that a Subscriber submits. Full access to the Support Tools is limited to personnel supporting the operations of the BlockCross System and compliance supervisory personnel. Employees responsible for operating the BlockCross System include Operations and Technology Personnel.

ILLC may also permission employees with read-only access to the Support Tools. Such employees can view all data described in the preceding paragraph, but they may not cancel orders or make any changes to standing instructions. Read-only access to the Support Tools is limited to Operations, Compliance, Technology, and ETP Personnel.

DESKTOP APPLICATION: The Desktop Application can transmit Subscribers' confidential trading information to the extent orders or trading interest is entered into the Front End or receives executions in BlockCross. Users with access to the Desktop Application may only access BlockCross data and cannot use the Desktop Application to access data from other Instinet ATSs.

ILLC may permission employees may with live access to the Desktop Application on a client-by-client basis. Such permissioned employees may view client orders, including open orders in the ATS specific to a given client. Permissioned employees may also view each order's status (e.g. whether the order has been matched, exposed via the Subscriber IOI functionality, or has been routed out of the ATS via an Instinet Algorithm). Technology and ETP Personnel responsible for customer support as well as Operations and compliance personnel may be permissioned, on a client-by-client basis, to access Subscribers' confidential trading information in this manner. Such personnel provide clients technology and order routing and execution support and, accordingly, are responsible for addressing Subscriber inquiries related to orders or trading interest that has been submitted to the Front End or has been executed in BlockCross. Sales and Trading Personnel may also be permissioned, on a client-by-client basis, to access the Desktop Application to provide order and execution support and analytics to clients who request it.

ILLC may permission employees may to access the Desktop Application on a post-execution basis, which allows a permissioned employee to view orders that have been executed in BlockCross, including the identity of the parties to each trade. Access to the post-execution view is limited to Technology and ETP Personnel responsible for customer support as well as Operations and compliance personnel. Sales and Trading Personnel may also be permissioned to access the Executions Support Tool to provide post-execution support and analytics to clients who request it.

PHYSICAL ACCESS: The data on the BlockCross System is accessible through direct access to the BlockCross System servers and databases. ILLC limits physical access to the BlockCross System servers and data bases to employees responsible for operating the system and further limits access to employees performing necessary IT functions. The BlockCross System servers and databases are housed in locked rooms requiring keycard access. Entry and exit is monitored via video surveillance.

CONNECTION TO ILLC SYSTEMS: Drop copies of BlockCross orders and executions are sent to the Core Messaging System at the end of each day in a single large batch file delivered after the close of trading. Each copy contains all relevant trade data for each order. BlockCross order information that has been drop copied to the Core Messaging System. However, the BlockCross System uses a dedicated FIX connection to transmit BlockCross execution information to the Core Messaging System, in real time, for the purposes of the clearance and settlement of transactions occurring in BlockCross.

ILLC SYSTEMS WITH ACCESS TO DIRECT SUBSCRIBER CONFIDENTIAL TRADING INFORMATION: ILLC data messages are periodically written to a database for storage and retention (the ''Core Database''). BlockCross orders and executions that have been copied to the Core Messaging System will also be written to the Core Database. This information includes both Direct and Indirect Subscriber order and execution information, as well as other ILLC data. Instinet maintains a Core Web Graphical User Interface (''Core Web GUI''), which allows a user to query the Core Database for the purposes of monitoring, reporting, and testing the Instinet systems and applications, including the ATS.

Access to the full Core Database via the Core Web GUI is limited to personnel supporting the operations of the Core Messaging System and related databases and compliance supervisory personnel. Employees responsible for operating the Core Messaging System include Operations and Technology Personnel and ETP Personnel whose responsibilities include the operation of the ATS. Members of the Liquidity Venues Team are permissioned to access Subscriber order and execution information. ATS data, including Direct and Indirect Subscriber order and execution information, is a subset of the data retained on the Core Web Database. ILLC personnel whose responsibilities include the operations of the ATS and related systems or its compliance with applicable rules, may be permissioned to access Subscriber order and execution information via the Core Web GUI. Other ILLC personnel may be permissioned for access to the Core Web GUI, but will be prevented from accessing Subscriber confidential trading information. ILLC reviews and permissions employees for access to the Core Web GUI in accordance with the policies and procedures outlined in Part II, Item 7(a) (ii) below.

ILLC limits physical access to its servers and databases to employees responsible for operating the system and generally further limits access to employees performing necessary IT functions. Instinet servers and databases are housed in locked rooms requiring keycard access. Entry and exit is monitored via video surveillance. ILLC reviews and permissions employees for physical access to Instinet's servers and databases in accordance with the policies and procedures outlined in Part II, Item 7(a) (ii) below.

As stated in response to Part II, Item 6, AWS provides cloud storage and retention of certain ILLC data. This information includes Direct and Indirect Subscriber order and execution information from the ILLC Core Messaging System, as well as other ILLC data. Initially, such information will be periodically transmitted to AWS for storage and retention in tandem with ILLC's internal Core Database. The purpose of this tandem transmission is to explore the feasibility of a third-party solution and replace the Core Database hardware and inhouse support tools described herein.

During this initial period, access to the Core Database will remain as described in this Part II, Item 7. Access to ILLC's data through AWS will be limited to Technology and Operations Personnel for the purpose of testing and implementing ILLC's transition to a third party solution for data storage and retention.

ILLC SYSTEMS WITH ACCESS TO INDIRECT SUBSCRIBER CONFIDENTIAL TRADING INFORMATION: The Newport OMS and Instinet Algorithms can transmit Subscribers' confidential trading information to the extent orders are managed by the Newport OMS or routed through an Instinet Algorithm. Data related to Indirect Subscriber orders managed by the Newport OMS or routed through an Instinet Algorithm is accessible through certain GUIs that can disseminate information regarding the destination market center for a given order (e.g., the ATS) and whether a previously routed order was executed or cancelled.

Through the Newport OMS, Technology and ETP Personnel who support the Instinet Algorithms or the OMS utilized may access real-time and post-trade Indirect Subscriber order and execution information routed or managed through the relevant strategy or OMS (Direct Subscriber order and execution information will not pass through an Instinet OMS or the Instinet Algorithm). Sales and Trading Personnel may also be permissioned, based on client coverage, to access real-time and post-trade order and execution via the Newport OMS. Note, certain members of the Electronic Sales Trading component group of the ILLC trading desk are considered client coverage for all clients utilizing the Instinet Algorithms.

The information available to such support or trading personnel is provided by systems supporting the relevant strategy or OMS and does not include information regarding an order's priority or status in the ATS or another market center. Information regarding ATS orders and executions that do not relate to the relevant strategy or were not managed by the OMS is not transmitted by these systems.

SUBSCRIBER CONFIDENTIAL TRADING INFORMATION SAFEGUARDS: ILLC requires permissioned logins to access Instinet Systems. Additionally, Instinet's global cyber security efforts, including measures to detect and prevent unauthorized access to Instinet systems, apply to ILLC and its affiliates, including the operation of the ATS. Relevant Principals and Supervisors must approve employee access to Instinet systems, including the ATS and the applications with the ability to access Subscriber confidential trading information outlined above.

SEPARATION: ILLC has implemented virtual information barriers to separate ATS data from other ILLC data and, in turn, separate personnel and systems with access to Subscriber confidential trading information from those not permitted to access such information.

ACCESS TO DIRECT SUBSCRIBER INFORMATION: Employees seeking to access the systems that may transmit or disseminate Direct Subscriber information (see above section titled Systems with Access to Direct Subscriber Confidential Trading Information) must receive approval from the ATS Operations Principal. In reviewing such requests, the ATS Operations Principal considers factors including the employee's current role and whether the employee performs a function related to the operations of the ATS and related systems or its compliance with applicable rules that requires access to Direct Subscriber information. An employee's request for access may be denied if, based on the ATS Operations Principal's review: (1) the employee's stated job function does not relate to the operations of the ATS and related systems or its compliance with applicable rules, (2) the employee has requested a type of permissioning (see below) that is too broad for the employee's stated job function, or (3) the employee can perform their stated duties without such access.

If an employee changes roles, the ATS Operations Principal will adjust the employee's access to appropriately reflect the employee's new role. Based on this review, the ATS Operations Principal or delegate may revoke, suspend, or modify access.

Decisions to approve access are subject to a periodic review pursuant to ILLC's Regulation ATS written supervisory procedures (''WSPs'') described below. On a monthly basis, the ATS Operations Principal or delegate conducts a review to confirm the appropriateness of user access to Subscriber confidential trading information, including verification that users whose roles have changed and/or, employees who have been inactive, transferred or terminated have their permissioned access modified accordingly. Based on this review, the ATS Operations Principal or delegate may revoke, suspend, or modify access.

ACCESS TO INDIRECT SUBSCRIBER INFORMATION: Employees seeking to access the systems that may transmit or disseminate Indirect Subscriber information (see above section entitled Systems with Access to Indirect Subscriber Confidential Trading Information) may be permissioned to do so on an as needed basis.

PERSONAL TRADING RESTRICTIONS: Instinet Incorporated maintains an Employee Investment Policy (the ''EIP'') which covers employees of all U.S. subsidiaries, and includes employees supporting the ATS. The EIP is designed to encourage long-term investments and prohibits employees from engaging in day-trading activities. Instinet prohibits all employees, including those with access to Subscriber confidential trading information, from trading based on non-public, or other confidential information.

The EIP requires employees to maintain EIP covered accounts at specified brokers that have agreed to provide Instinet daily trading information for employee personal accounts. EIP covered securities are subject to a 15-day holding period.

Prior to entering any trades in a personal account covered by the EIP, employees must enter a trade approval request via the Personal Trading Control Center (''PTCC'') tool and receive an approval from both their supervisor and PTCC group. The PTCC tool requires the employee to certify that the employee: (1) is not in possession of any material non-public information concerning the security or commodity the employee proposes to buy or sell; (2) does not know of a pending customer trade nor of a pending research report in the security or commodity; (3) is not engaging in personal trading activity that violates Instinet's policies and procedures, including the Code of Ethics, or any duties owed to Instinet or its clients; (4) has reviewed Instinet's restricted list and the proposed transaction is not on the restricted list; (5) has confirmed that the proposed transaction meets the holding period requirement; (6) agrees that the proposed transaction must be effected on the same day on which approval is given; and (7) has confirmed that the proposed transaction(s) does not involve the purchase of an initial public offering (IPO) or any other type of new equity issue.

In approving or denying such a request, supervisors may review the employee's trades for any unusual activity, possible front-running customer trades or research, or conflicts with any of Instinet's businesses.

In addition, supervisors consider whether transactions are appropriate, given the employee's economic status and investment experience and whether the transactions are of such a frequency that they may distract the employee from his or her responsibilities at Instinet. Separately, the Compliance Department reviews personal trades daily and consults with managers if irregularities are identified. Generally, if an approval for an employee trade is given, it remains in force for the trading day in which it was received. Once an employee receives written confirmation approving a covered transaction, the employee may enter a trade in that symbol. Employee supervisors review each employee's trading activity on a post trade basis and check for irregularities and potential red flags. In the event any irregularities or red flags are discovered, supervisors are to escalate the matter to Instinet management and the ILLC Chief Compliance Officer. Instinet, in its discretion, may take any action against an employee found to have violated the EIP, up to and including termination.

CONFIDENTIAL INFORMATION AND INSIDER TRADING: Instinet Incorporated maintains a policy regarding confidential information and insider trading which covers employees of all U.S. subsidiaries, including employees supporting the ATS.

Employees must not disclose any confidential information to anyone who is not authorized by Instinet to receive it pursuant to these policies and may not use such information, other than in the course of their employment and in connection with the performance of the duties for which access to such information has been granted. Accordingly, employees may not use confidential information to: (1) trade securities for their own accounts, accounts in which they have a direct or indirect beneficial interest, or accounts over which they can exercise control; or (2) advise relatives, friends, or other persons about possible securities transactions. Nor may employees authorize anyone else to disclose or use confidential information in a manner that would violate these prohibitions.

WRITTEN PROCEDURES: ILLC's Regulation ATS WSPs provide specific guidelines for the initial review and approval process, as well as the ongoing evaluation of, employee access to ATS data. Prior to granting any employee access to Instinet's systems, including the ATS and the applications with the ability to access Subscriber confidential trading information must review and document each employee's level and type of access requested, the role and responsibilities of the employee, and the purpose for which access was requested. On a monthly basis, employee access is reviewed by the ATS Supervisor to determine whether their level of access to Instinet's systems, including the ATS and the applications with the ability to access Subscriber confidential trading information remains appropriate. The ATS Supervisor must document each review and the changes made, if any, to employee access.

Periodically, the Internal Audit group reviews the ATS operations generally. Such reviews typically include testing the ATS WSPs, assessing the ATS Supervisor's review of employee access, and confirming that each review has been properly documented. 

ILLC considers all Subscribers to the ATS to have consented to the disclosure of their confidential trading information as described in Part II, Items 6(a) and 7(a) above and in the following ways.

MARKETING: ILLC may include, in marketing materials or client presentations, aggregated and anonymous analysis related to order and execution statistics derived from orders and executions in the ATS. Subscribers do not have the ability to opt out of the use of their related order and execution information for ILLC marketing purposes.

CLIENT COVERAGE: ILLC may permission the systems and personnel described in Part II, Items 6(a) and 7(a) to access Subscriber (both Direct and Indirect Subscribers) confidential trading information. Subscribers may request to limit such disclosure, with respect to Sales and Trading Personnel, in accordance with the procedure described in response to Part II, Item 6(c) below. ILLC reserves the right, in its sole discretion, to honor such requests and will review each request on a case-by-case basis. Typically, ILLC will honor such requests by adjusting a client's coverage model to reflect the client's requested opt out.

THIRD PARTIES: ILLC does not disseminate Subscriber confidential trading information to third parties, other than those listed in Part II, Item 6(b), except where required by applicable law. Subscribers may request that ILLC share their confidential trading information with third parties at their discretion.

BlockCross advertises the BLKX ATS intraday real-time trading volumes via Bloomberg. Such trade advertising on Bloomberg includes all transactions executed in BLKX unless one or both Subscribers have opted out of participating in trade advertising. BlockCross Subscribers can opt out of participating in BlockCross trade advertising by contacting the BlockCross ATS Support team, either via phone or in writing (including electronic, however made). No identifying or confidential trading information is included in such advertising, which only includes the trading symbol and the quantity of shares crossed on the ATS. The advertised trades are identified as volume of the BlockCross ATS ("BLKX") and not of any specific Subscriber. As noted above, trades will not be included in such trade volume advertising on Bloomberg if that trade included a Subscriber who has opted out of participating in such advertising. Once a trade is executed on the BlockCross ATS, the transaction is reported and is concurrently run through BlockCross internal processes to determine if either side of the transaction is not a participant in BlockCross trade volume advertising. If so, that transaction is not submitted to Bloomberg for advertising. If not, that transaction is submitted to Bloomberg for advertising. 

Subscribers may request to withdraw their consent to the information described above by contacting their sales representative or the BlockCross ATS support team in writing via email or instant message. Subscribers making such requests will receive written notification regarding their request to opt-out as soon as practicable. ILLC conducts periodic reviews of opt out requests to ensure that such requests have been implemented. 

The persons described in response to Part II, Item 6(a) and (b) have access to Subscriber confidential trading information. The type of information that such persons can access along with the reasons for such access is described in response to Part II, Item 6(a) and (b). 

Only clients of ILLC with accounts approved for trading may be Subscribers of the ATS. Prior to establishing a trading account for a prospective client, ILLC will require (1) the client's name, address and other identifying information, as well as the name of any adviser/agent authorized to trade for the account; (2) the citizenship (or place of incorporation) of the client; (3) a Taxpayer Identification Number or equivalent; (4) the type of client, e.g., registered investment adviser, registered broker-dealer, etc.; (4) the names of the persons designated by the client for trading authorization; (5) clearing instructions, including, where applicable, the identity of the client's prime broker or custodian (ILLC does not custody customer securities); and (6) a completed account application, client agreement and supplementary documentation, as appropriate. ILLC does not admit natural persons as Subscribers to the ATS. Prospective clients must also pass ILLC's AML/KYC/CIP risk assessments, as well as any credit assessments.
ILLC reserves the right to prevent or otherwise limit a prospective Subscriber from accessing the ATS if they fail to meet the requirements to become a client, in ILLC's sole discretion. ILLC may prevent or otherwise limit any client's access to the ATS. Factors that may be considered in preventing or otherwise limiting a client from accessing the ATS include, but are not limited to, reputational risk to Instinet, failure to make timely and proper settlement of transactions, regulatory actions or findings suggesting inappropriate activity, or a failure to satisfactorily respond to an information request.

For purposes of access to the ATS, Subscribers are not required to enter into any specific clearing arrangement. 

ILLC may prevent or otherwise limit any Subscriber's access to the ATS if they fail to meet the requirements to become a client or ILLC decides to terminate its relationship with the client based on factors related to the client's activity within the ATS or otherwise. As set forth in the Client Agreement, ILLC may, at any time, without cause or notice, (i) suspend or terminate all or part of the ATS or other Instinet services or a client's access thereto, (ii) change the nature, composition or availability of all or a portion of the Instinet services or (iii) change any limits or restrictions on the trading or other activities a client may conduct through the Instinet services. If a client's passwords or other access methods ("Access Methods") are lost, stolen or compromised, ILLC will cancel or suspend the access methods upon receipt of notice from the client. ILLC may terminate, revoke, suspend, modify or change any or all of a client's Access Methods at any time, without prior notice, in its sole and exclusive discretion.

ILLC may, in its sole and absolute discretion, reject any order that exceeds established limits, appears to be entered in error, or is otherwise unacceptable.

ILLC may also terminate its relationship with a client, and by extension, prevent or otherwise limit a Subscriber's access to the ATS based on factors including, but not limited to, reputational risk to Instinet, failure to make timely and proper settlement of transactions, regulatory actions or findings suggesting inappropriate activity, or a failure to satisfactorily respond to an information request. For instance, ILLC has terminated client access to ILLC's services due to client failure to adequately address compliance questions relating to the client's trading activity.

Subscribers who have registered their trading interest on the Front End, and utilize the Desktop Application, may receive Activity Alerts (See Part III, Item 9) to notify the Subscriber of potential contra-side activity in the Front End.

Activity Alerts are automatically generated by the Front End from time to time throughout the trading day in accordance with parameters set by ILLC in its sole discretion. ILLC will work with Subscribers to customize such parameters thereby allowing Subscribers to tailor the amount and frequency in which they receive Activity Alerts. For example, Subscribers who have requested to receive no more than a certain number of Activity Alerts during a predetermined time period (e.g., over the course of one day) would not receive additional Activity Alerts once that threshold has been met. ILLC will implement such requests in its sole direction. 

As noted above, ILLC may, in its sole discretion, exclude a Subscriber from BlockCross, or suspend or withdraw access in whole or in part. Any suspension of ILLC, in its capacity as a Subscriber to the ATS, is likely to be temporary, and to arise from a technical issue or another event that presents a risk to the ATS system or another Instinet service. 

BlockCross accepts orders from 2 a.m. ET to 4 p.m. ET. BlockCross matches and executes orders from 9:30 a.m. ET to 4 p.m. ET. During market holidays or shortened trading days this period of operation will be amended. Orders received when BlockCross is not in operation are rejected and open orders, if any, are canceled back at the end of trading hours. 

BACKGROUND: ILLC offers its clients electronic order handling and execution products and services including the Instinet Trading Products (See Part II, Item 5), and direct access to the ATS. Additionally, ILLC offers its clients order routing and execution support services through the component groups of ILLC's trading desk listed in Part II, Item 1.

Subscribers submit orders to BlockCross via the Front End. Subscribers may submit trading interest to the Front End automatically via blotter integration or manually via FIX connection. Subscribers may also manually submit orders to the Front End by using the BlockCross Desktop Application. All trading interest accesses the ATS via the Front End, including orders routed to BlockCross by the Instinet Algorithms and SOR. All Subscribers may utilize these products and services.

INSTINET ALGORITHMS: A Subscriber utilizing an Instinet Algorithm may select a strategy that, where applicable, may route orders or trading interest to BlockCross. Instinet Algorithm orders routed to BlockCross access the ATS via the Front End. Orders routed to BlockCross by any of the specific Instinet Algorithms will be prioritized, matched, and executed in accordance with the matching and execution logic outlined in Part III, Item 11.

SOR: Orders that are routed to BlockCross via the SOR access the ATS via the Front End and will be prioritized, matched, and executed in accordance with the matching and execution logic outlined in Part III, Item 11.

OMS/EMS: The Instinet OMSs allow users to access the ATS in the following ways: (i) by directing trading interest to the ATS, (ii) by utilizing an Instinet Algorithm (to the extent offered by the Instinet OMS and permissioned to access the ATS), and (iii) by otherwise submitting a non-directed order to ILLC for further handling by trading desk personnel or by entering the order in the SOR. Orders that are routed to BlockCross by the above listed means access the ATS via the Front End and will be prioritized, matched, and executed in accordance with the matching and execution logic outlined in Part III, Item 11.

FRONT END: The Front End allows for possible matching and execution within BlockCross and also offers the client the ability to utilize Instinet Algorithms to seek contra-side interest for their trading interest. Additionally, the Front End allows users to utilize the conditional order and IOI functionalities discussed in Part III, Item 9. Orders entering the ATS via the Front End will be prioritized, matched, and executed in accordance with the matching and execution logic outlined in Part III, Item 11.

In addition to the means of accessing the ATS listed above, Subscribers may submit trading interest to the Front End manually via FIX connection or by integrating the Subscriber's order book (in whole or in part) via blotter integration. Blotter integration occurs when the Front End is integrated directly with another system that contains information relating to that Subscriber's trading interest, such as a Subscriber's order management system. Blotter integration is an automated solution that allows a Subscriber to copy and continuously and automatically "synchronize" all or a designated portion of its order blotter into the Front End. Only Subscribers that utilize the Front End in conjunction with the BlockCross Desktop Application may utilize blotter integration.

Trading interest registered to the Front End will reach the ATS once a potential match is identified and following the post-match requirements of each trading mode (e.g., Firm up process for trading interest submitted in Confirm Mode) and any verification required by the order type (e.g., uncommitted orders).

DESKTOP APPLICATION: The Desktop Application allows users to "manually" manage their trading interest registered to the Front End (e.g., designate orders as committed or uncommitted, select a specific trading mode, or utilize the conditional order and IOI functionalities discussed in Part III, Item 9). Only Subscribers that utilize the Desktop Application may "manually" manage their trading interest registered to the Front End or receive Activity Alerts, Subscriber Generated IOIs, or Agency IOIs (See Part III, Item 9). Subscribers that do not utilize the Desktop Application may set personalized rules regarding the handling and automatic routing of trading interest registered on the Front End. 

Only Subscribers that utilize the Desktop Application in conjunction with the Front End may utilize blotter integration. Only Subscribers that utilize the Desktop Application may "manually" manage their trading interest in the ATS. Subscribers that do not have the Desktop Application may set personalized rules regarding the handling and automatic routing of orders submitted to the Front End.

Subscribers who have registered their trading interest on the Front End, and utilize the Desktop Application, may receive Activity Alerts (See Part III, Item 9) to notify the Subscriber of potential contra-side activity in the Front End.

Activity Alerts are automatically generated by the Front End from time to time throughout the trading day in accordance with parameters set by ILLC in its sole discretion. ILLC will work with Subscribers to customize such parameters thereby allowing Subscribers to tailor the amount and frequency in which they receive Activity Alerts. For example, Subscribers who have requested to receive no more than a certain number of Activity Alerts during a predetermined time period (e.g., over the course of one day) would not receive additional Activity Alerts once that threshold has been met. ILLC will implement such requests in its sole direction. 

ORDER TYPES: The ATS accepts both "buy" and "sell" orders. BlockCross offers market orders, limit orders, and pegged orders. "Market" is an order to buy or sell immediately at the best available price. "Limit" is an order to buy or sell at a specified price or better. "Pegged" is an order to buy or sell at a price relative to a benchmark reference price.

All Subscribers may submit orders to sell "long" or "short," but only broker-dealer Subscribers may submit orders marked "short sale exempt." All of the above listed order types are available across all forms of connectivity to the ATS. All of the above pricing instructions are available for both committed and uncommitted orders and in both AutoEx and Confirm modes.

PRIORITY: BlockCross supports two trading modes: AutoEx and Confirm mode (See Part III, Item 11 for a discussion of Trading Modes). Both AutoEx and Confirm modes allow for "committed" and "uncommitted" orders. Orders submitted in any trading mode, whether committed or uncommitted, are executed based on strict time priority, marketability and in accordance with the order's designated trading mode and any Subscriber-selected counterparty restrictions (i.e. for priority purposes, the ATS does not differentiate between orders based on trading mode or whether the order is committed or uncommitted). Additionally, uncommitted orders retain their time priority when converted to and from committed orders.

No two orders can enter BlockCross at precisely the same time, so time priority is determined by the actual time an order is received by BlockCross. The ATS does not adjust the time of receipt of pegged orders to account for reference price changes. Except as otherwise noted herein, all orders will retain the original time-stamp received upon entry to the ATS.

PRICING INSTRUCTIONS: BlockCross currently supports the following reference prices for pegged orders: (1) Last Executed Price: limit is derived from the last executed trade price as published to the consolidated tape; (2) Volume Weighted Average Price: limit is the trading day's current volume-weighted average price as determined by IMDS; (3) Midpoint: limit is the current midpoint of the NBBO; (4) Market: limit is the current national best offer ("NBO") for buy orders and current national best bid ("NBB") for sell orders; and (5) Primary: limit is the current NBB for buy orders and current NBO for sell orders. The ATS does not adjust the time of receipt of pegged orders to account for reference price changes.

Orders pegged to the NBB or NBO may include a peg-offset (e.g., Buy 100 shares XYZ pegged at the NBB plus/minus $.02). For orders priced at $1.00 per share or higher, peg-offsets may only be expressed in whole penny amounts. Orders pegged to the midpoint of the NBBO may not include a peg-offset.

COMMITTED AND UNCOMMITTED ORDERS: Subscribers may submit orders to the ATS designated as "committed" or "uncommitted." A committed order is an order submitted by a Subscriber for execution on BlockCross where the shares are unavailable for execution on any other platform. An uncommitted order is a "conditional" order submitted by a Subscriber to BlockCross where the shares underlying the order are being represented at another market center. Uncommitted orders are not executed on BlockCross until BlockCross has verified that the Subscriber's shares are still available.

Generally, Subscribers registering trading interest on the Front End may submit both committed and uncommitted orders. Trading interest submitted to the Front End automatically via blotter integration is submitted on an uncommitted basis.

TIME IN FORCE: Subscribers that submit orders or trading interest to the Front End for possible matching and execution in BlockCross through a FIX connection may designate their orders as either "day" or immediate or cancel ("IOC"). The IOC instruction is available in both AutoEx and Confirm mode. Orders designated as immediate or cancel may only be submitted as committed orders and are canceled promptly following their submission unless those orders are immediately matched (i.e., against an existing resting order) in BlockCross. In either mode, following an initial match, the matching logic will repeat until the IOC order is fully filled or no longer matches a contra order. Subscribers submitting orders as IOC must set standing instructions regarding the handling of IOC orders following a match (i.e., preselect an amount of time where the matching logic will attempt subsequent matches prior to cancelling the IOC order).

By default, BlockCross designates all orders submitted manually to BlockCross by Subscribers using the Desktop Application as "day" orders.

BlockCross Subscribers utilizing the Desktop Application may also utilize the following timing options: (1) Automatic cancelation of "day" orders in the event the remaining shares are less than 2,500 shares after a partial fill; (2) Automatic cancelation of "day" orders that have not received a partial fill from BlockCross within a period of time configurable by the Subscriber (the configured period of time will reset after each partial fill); (3) Automatic cancelation of "day" orders where the Subscriber logs out of or is otherwise disconnected from the Desktop Application, unless the relevant Subscriber has provided a separate standing instruction to the Firm indicating this event should not result in the removal of any orders from the ATS; and (4) Automatic cancelation of "market" orders for Subscribers that have instructed that every order have a limit and the Subscriber has submitted an order through the Front End without a limit.

Subscribers not electing to utilize the Desktop Application may also include the following timing options: (1) Automatic cancelation of "day" orders in the event the remaining shares are less than 2,500 shares after a partial fill; (2) Automatic cancelation of "day" orders in the event that the connectivity between the Subscriber's systems and the ATS or Front End, as applicable, is disconnected; (3) Automatic cancelation of "day" orders that have not received a partial fill from BlockCross within a period of time configurable by the Subscriber (the configured period of time will reset after each partial fill); and (4) Automatic cancelation of "market" orders for Subscribers that have instructed that every order have a limit and the Subscriber has submitted an order through the Front End without a limit.

BlockCross treats all uncommitted orders as "day" orders. However, if the ATS is informed that the shares underlying an uncommitted order have been removed from the Subscriber's blotter, the ATS will cancel the relevant uncommitted order.

ORDER MODIFICATION: Subscribers may modify, replace, or cancel their orders at their discretion. Except as noted below, modifications to a Subscriber order (e.g. switching trading modes for a specific order or changing the orders designation as committed or uncommitted) do not affect the order's priority. Orders that are cancelled will not maintain their original priority.

As described in Part III, Item 8 below, BlockCross has certain minimum size requirements. In the event a Subscriber enters an order or trading interest in Confirm Mode, in a quantity below the required minimum, and subsequently raises the share quantity to a value at or above the minimum size requirement, that order will not retain its original priority.

ROUTABILITY: Subscribers may route orders through the Front End to the ATS and to other market centers, including other alternative trading systems operated by ILLC. Subscribers may elect to represent in the ATS, on a conditional basis, trading interest routed to another market center (i.e., submit an uncommitted order to the ATS where "firm" trading interest has been submitted to another market center). Where eligible contra-side interest exists, the ATS will request that the Front End "confirm" an uncommitted order in the ATS. Following such a confirmation, the ATS will release any unexecuted shares back to the Front End, which may route those shares to another market center, including other alternative trading systems operated by ILLC. The ATS is not involved in any such routing determinations. 

Only broker-dealer Subscribers may submit orders marked short-sell exempt. 

MINIMUM SIZE REQUIREMENTS: AutoEx orders must have a minimum quantity of 2,500 shares per match. Subscribers may register trading interest of any size on the Front End. Trading interest less than 2,500 shares is ineligible for matching within BlockCross. For example, a Subscriber utilizing blotter integration may allow AutoEx orders comprising less than 2,500 shares to be registered on the Front End; however, such orders will be ineligible for matching. Subscribers may also elect to have the Front End system disregard AutoEx orders for less than 2,500 shares (i.e., the blotter integration functionality would not register specific trading interest on the Front End for such a Subscriber unless such trading interest is for 2,500 shares or more). BlockCross does not aggregate orders for matching or execution.

Confirm Mode orders must have the minimum quantities set forth below as determined by the underlying security's 30-day average daily trading volume: Micro - 0 to 1,000,000 average daily volume - 5,000 share minimum quantity; Medium - 1,000,001 to 10,000,000 average daily volume - 25,000 share minimum quantity; Large - 10,000,001 and up average daily volume - 100,000 share minimum quantity. Trading interest submitted in Confirm Mode that fails to meet these minimum quantities are ineligible for matching within BlockCross. For example, a Subscriber utilizing blotter integration may allow Confirm mode orders comprising less than the required minimum shares to be registered to the Front End; however, such orders will be ineligible for matching. Subscribers may also elect to have the Front End system disregard Confirm mode orders comprising less than the required minimum shares.

ACTIVITY ALERTS AND INDICATIONS OF INTEREST: The Front End includes certain messaging and conditional order functionality as discussed in Part III, Item 9. Activity Alerts are system generated messages indicating contra-side activity that has been submitted to the Front End in AutoEx mode. Accordingly, to be eligible to receive Activity Alerts Subscribers must have contraside interest registered to the Front End, set for AutoEx mode, and comprising at least 5,000 shares. Additionally, the system will not generate Activity Alerts for trading interest registered to the Front End that comprises less than 5,000 shares or that has been submitted in Confirm mode.

Subscriber Generated IOIs may only be sent by Front End users that have registered their trading interest in Auto Ex mode and such users may only IOI an amount of shares less than or equal to the amount of shares submitted in Auto Ex mode and cannot IOI less than the 5,000 share minimum quantity. Subscribers may receive Agency IOIs for any amount. 

BlockCross will accept any order subject to any instructions placed on such order by the Subscriber. BlockCross will execute any order that satisfies the minimum order quantity requirements, including a mixed lot order that is not an even multiple of one hundred shares. BlockCross will not execute odd-lot orders. 

BlockCross will execute any order that satisfies the minimum order quantity requirements, including a mixed lot order that is not an even multiple of one hundred shares. By default, mixed lots are treated the same as round lots. However, BlockCross ATS offers functionality to allow Subscribers to limit their order executions to round lots; if a Subscriber elects to use this functionality, BlockCross ATS automatically rounds down the execution amount for both sides of the potential trade to the nearest hundred shares. 

SUBSCRIBER GENERATED IOIS: BlockCross Subscribers that are institutional clients and broker-dealers that have submitted trading interest to the ATS on an agency basis may elect to transmit indications of interest ("IOIs") to BlockCross Subscribers that utilize the Desktop Application and have eligible contra-side registered on the Front End (whether that interest be committed or uncommitted and without regard to which trading mode the interest is set) and to one or more classes of users of third-party financial information aggregators (Bloomberg and NYSE's ioinet) (such IOIs, "Subscriber Generated IOIs"). Only Subscribers may generate such IOIs and, accordingly, neither the Front End, the ATS, nor ILLC determines whether to transmit such IOIs. Only Subscribers that utilize the Desktop Application and access the ATS via the Front End may manually transmit Subscriber Generated IOIs.

Subscriber Generated IOIs are disseminated by the Front End. However, to send a Subscriber Generated IOI, a Subscriber must have registered a committed or uncommitted order on the Front End for execution in AutoEx mode for at least the quantity of shares that are the subject of the IOI. Subscriber Generated IOIs must be for at least 5,000 shares.

Eligible recipients of Subscriber Generated IOIs include all Desktop Application users with eligible contra-side interest in the ATS (whether that interest be committed or uncommitted) and to certain classes of non-Subscribers, as determined by the Subscriber. When electing to send a Subscriber Generated IOI, the Subscriber can choose to display such IOIs to one or more of the following classes of non-Subscribers: (i) all buy-side institutions; (ii) the fifty largest buy-side institutions as measured by U.S. equity assets under management; and (iii) buy-side institutions with more than $10 billion in U.S. equity assets under management, in each case as determined by information provided by an independent third party data provider. Additionally, all Subscribers may request, from time to time, that a customized distribution list be created based upon particular recipient characteristics, provided, however, that ILLC would not expect any such customized list to be comprised of less than twenty institutions.

Subscriber Generated IOIs that are distributed to other BlockCross Subscribers (Subscriber must be a Desktop Application User and have contraside interest in the ATS) identify side, symbol and size. Subscribers receiving a Subscriber Generated IOI receive a "pop-up" message on their Desktop Application alerting the Subscriber to the trading opportunity. Such Subscribers then elect to trade by setting their trading interest for AutoEx, in which case execution occurs automatically, or the Subscriber may reject the IOI.

Subscriber Generated IOIs that are distributed to third-party financial information aggregators identify symbol and side. If the recipient of a Subscriber Generated IOI is not a Subscriber to BlockCross, it may contact a broker-dealer that is a Subscriber (e.g., ILLC) and instruct that broker-dealer to submit an order for execution to BlockCross.

The ATS does not differentiate between orders submitted in response a Subscriber Generated IOI and other trading interest submitted in ordinary course of operation. Accordingly, orders that are the basis for, or submitted in response to, a Subscriber Generated IOI are subject to the ATS' standard priority, matching, and execution logic. In essence, an order submitted in response to a Subscriber Generated IOI may execute with the trading interest underlying the IOI or may execute with other trading interest in the ATS based on priority.

AGENCY IOIS: ILLC is a Subscriber to the ATS. The ILLC agency trading desk may transmit IOIs to those ATS Subscribers that have elected to download and use versions of the BlockCross Desktop Application that include the IOI functionality (Subscribers may choose to continue to use certain legacy versions of the Desktop Application where this functionality was not in operation) and that have opted in to receiving IOIs in this manner (such IOIs, "Agency IOIs").

Only ILLC is permitted to submit Agency IOIs. Subscribers must notify ILLC that they would like to receive Agency IOIs and establish a relationship with the ILLC agency trading desk if they wish to receive Agency IOIs. The ILLC agency trading desk is notified of the Subscriber's identity so that they may establish a relationship with the Subscriber.

Agency IOIs notify the Subscriber of targeted trading opportunities on the ILLC agency trading desk by comparing the symbol and side of IOIs submitted by the ILLC trading desk to the Subscriber's trading position information in the Front End. This comparison occurs solely in the Front End and only Subscribers that have the relevant contra-side trading position represented in the Front End actually receive the Agency IOI. Accordingly, if the ILLC agency trading desk directs an Agency IOI to a particular Subscriber, the absence of a response from that Subscriber could be due to a lack of interest in entering into the transaction in the underlying security or because the Subscriber never received the Agency IOI because it did not have a contra-side trading position in the underlying security.

The ILLC agency trading desk does not have access to Subscriber order or trade position information in the Front End. Positions that are in the Front End, include those orders that are also submitted on a committed or uncommitted basis to BlockCross.

Subscribers receiving an Agency IOI would receive a "pop-up" message on their Desktop Application alerting the Subscriber to the trading opportunity. The "pop-up" message displays to the receiving Subscriber symbol, side, and size of the trading opportunity. If the Subscriber is interested in the trading opportunity presented by an Agency IOI, it may use functionality built into the BlockCross Desktop Application to establish communication with the ILLC agency trading desk and begin negotiations regarding a potential transaction related to the interest underlying the Agency IOI, or may communicate with the ILLC agency desk though other means. If the Subscriber elects to initiate a negotiation with the ILLC agency trading desk, the Subscriber's order or trading interest (whether the order or trading interest is represented in the Front End or the Front End and ATS) remains eligible for matching on BlockCross unless the Subscriber chooses to route the order to the ILLC agency desk or otherwise makes its order or trading interest ineligible for execution in BlockCross (e.g., cancelling, changing the terms (size, limit price, minimum quantity, etc.), or by switching the designated trading mode (AutoEx/Confirm Mode)). ILLC would act as broker and agent for both the Subscriber and the other party to the transaction that placed the order being represented by the Agency IOI. Such transactions would be negotiated and executed by the ILLC agency desk and would not be executed in the ATS.

If the Subscriber does not elect to initiate a transaction with the ILLC agency trading desk, no information is communicated to the ILLC agency trading desk regarding the Subscriber's order or trade position.

The Agency IOI functionality does not actually execute IOIs, nor does it allow for any Subscriber name, order or trade position information to flow from the Front End to the ILLC agency trading desk. However, as described above, the ILLC agency trading desk is aware of which Subscribers have opted in to receive Agency IOIs. The ILLC agency trading desk may elect (based upon which Subscribers it knows can receive Agency IOIs) to direct any particular Agency IOI to some, but not all, eligible Subscribers at its sole discretion. In these circumstances, the ILLC agency trading desk does not know whether any of the selected Subscribers have the relevant contra-side trading position that is necessary to actually receive the Agency IOI.

ACTIVITY ALERTS: Activity Alerts are a functionality of the Front End which notifies certain Subscribers of potential contra-side activity in the Front End that would otherwise be ineligible to match due to a variety of factors (e.g., when the Subscriber submitted the order in AutoEx mode, the Subscriber elected to set a minimum quantity that was greater than the available contraside interest). Activity Alerts notify Subscribers of such potential contra-side interest and allows the Subscribers on both sides to re-evaluate their previously selected order parameters (e.g., a Subscriber may remove their previously selected minimum quantity and accept a match for a lower number of shares).

Activity Alerts are automatically generated by the Front End from time to time throughout the trading day in accordance with parameters set by ILLC in its sole discretion. ILLC will work with Subscribers to customize such parameters thereby allowing Subscribers to tailor the amount and frequency in which they receive Activity Alerts. For example, Subscribers who have requested to receive no more than a certain number of Activity Alerts during a predetermined time period (e.g., over the course of one day) would not receive additional Activity Alerts once that threshold has been met. ILLC will implement such requests in its sole direction. The contra side information that may generate an Activity Alert includes both orders entered into the Front End System with an instruction from the Subscriber to automatically route to BlockCross and trading positions in a trade blotter integrated with the Front End System for which a Subscriber may or may not have provided instructions that its trading positions be routed to BlockCross. The Subscribers receiving an Activity Alert each receive a "pop-up" message on their Desktop Application. This message displays to each Subscriber the symbol and side of the potential trading opportunity and allows each Subscriber to accept or reject the message. In the event a Subscriber elects to accept the message, that Subscriber will receive an additional "pop-up" message and will be prompted to enter a size and limit price in the pop-up. If after each Subscriber makes the required entries, there is a match, the orders will execute (subject to any necessary verification of uncommitted trading interest) pursuant to the standard procedures described in Part III, Item 11(c). If one or both Subscribers receiving the message reject the Activity Alert, no matching occurs and the trading interest of both Subscribers retains its original parameters (e.g., price and size) and priority.

Activity Alerts do not identify the Subscriber with the contra side trade position or the size of the contra side order and will only be delivered to a Subscriber with contra-side interest in the Front End that satisfies the minimum trade order size requirements of BlockCross.

In order to receive Activity Alerts, a Subscriber must utilize the Front End in conjunction with the Desktop Application and have contraside interest that has been submitted in AutoEx mode. Those Subscribers that do not use the Desktop Application do not receive any Activity Alerts. Subscribers will only receive Activity Alerts related to contra-side activity submitted in AutoEx mode. Subscribers receiving Activity Alerts will not receive such alerts related to trading interest that has been submitted in Confirm Mode. Similarly, the Front End will not generate Activity Alerts based on trading interest submitted in Confirm Mode.

No Subscriber may opt out of having its information serve as the basis for an Activity Alert and no Subscriber that uses the Desktop Application functionality may opt out of receiving an Activity Alert.

UNCOMMITTED ORDERS: Subscribers may submit orders or trading interest designated as "committed" or "uncommitted." A committed order is an order submitted by a Subscriber for execution on BlockCross where the shares are unavailable for execution on any other platform. An uncommitted order is a "conditional" order submitted by a Subscriber to BlockCross where the shares underlying the order are being represented at another market center.
In the event of a match where shares on one or both sides of the trading opportunity are uncommitted, the order will not execute until BlockCross has verified that the Subscribers' shares are still available. The ATS verifies that uncommitted trading interest is available following a match with eligible contraside trading interest by sending a "message" to the Subscriber's OMS system requesting that the Subscriber's OMS route any necessary and available shares (i.e., the shares that may be executed based on the match) to the ATS. The Subscriber's OMS system either responds by submitting a firm order or responds with a message back informing the ATS that the uncommitted shares are no longer available. Such messages do not identify the Subscriber with the contra side trade position.

CONFIRM MODE: Confirm mode allows Subscribers to submit conditional order interest to BlockCross that Subscribers must confirm or "firm-up" prior to any execution (such confirmation separate from verifying the availability of any uncommitted shares). The execution of an order in Confirm mode requires both Subscribers to a potential transaction to acknowledge a Preliminary Match (i.e., authorize the execution of their orders) within thirty seconds of the Preliminary Match.

Subscribers utilizing the Desktop Application are notified of a Preliminary Match by a "pop-up" message on their Desktop Application. This message displays symbol and side of the trading opportunity. Upon receipt of this message, each Subscriber may elect to trade, in which case each Subscriber must enter the number of shares they wish to trade. Subscribers may also elect to reject such messages. In the event both Subscribers elect to trade, the order will execute in the amount of the lesser of the two sizes entered (subject to any required verification of uncommitted shares) pursuant to the standard procedures described in Part III, Item 11(c). If one or both Subscribers receiving the message elect not to trade, no matching occurs and the trading interest of both Subscribers retains its original parameters (e.g., price and size) and priority. Desktop Application users may also establish a standing instruction to either (i) automatically accept, at the end of the thirty second confirmation time period, any Preliminary Matches under Confirm mode that the Subscriber has not otherwise manually rejected or accepted or (ii) automatically and immediately accept all Preliminary Matches under Confirm mode.

As stated above, Subscribers that use the Desktop Application may manually confirm a match; however Subscribers that do not utilize the Desktop Application must, to the extent they wish to utilize Confirm Mode, establish a standing instruction to automatically and immediately accept all Preliminary Matches.

Subscribers may submit uncommitted orders in confirm mode. In confirm mode, if a Subscriber integrates with the ATS through blotter integration, its order will always be designated as uncommitted. By default, the ATS will request the shares underlying an uncommitted order before notifying both parties of the match. If the shares are available, then the ATS will convert the order to a committed order for the duration of the match and notify both parties of the match. However, Subscribers that use the Desktop Application in conjunction with blotter integration may elect that the verification and conversion of an uncommitted order be delayed until the Subscriber has acknowledged a confirm match.

Once a Subscriber has been notified of a Preliminary Match, the order subject to that match becomes unavailable for other matching opportunities in the ATS during the "firm-up" period.

If a Subscriber on either side of a potential trade in Confirm trading mode fails to affirmatively acknowledge a match within the allotted thirty-second confirmation time period described above then no execution will result from the Preliminary Match. Further, where a Subscriber fails to affirmatively acknowledge a Preliminary Match within the thirty second confirmation time period, that Subscriber's order will be removed from the ATS, along with any other orders that Subscriber has in the ATS with the same symbol and side. If a Subscriber affirmatively acknowledges a Preliminary Match in circumstances where the other Subscriber to a potential trade does not, the Subscriber acknowledging the Preliminary Match will receive a message indicating that the match has timed out, although its order will not be cancelled and will retain its original time priority status. 

Only institutional Subscribers and broker-dealer Subscribers acting in an agency capacity that utilize the Desktop Application and access the ATS via the Front End may manually transmit Subscriber Generated IOIs. Only institutional clients that use the Desktop Application may receive Subscriber Generated IOIs.
Only ILLC may send Agency IOIs. Only those ATS Subscribers that have elected to download and use versions of the BlockCross Desktop Application that include the IOI functionality (Subscribers may choose to continue to use certain legacy versions of the Desktop Application where this functionality was not in operation) and that have opted in to receiving IOIs in this manner may receive Agency IOIs.
Only users of the Desktop Application may receive Activity Alerts.
Alerts are automatically generated by the Front End from time to time throughout the trading day in accordance with parameters set by ILLC in its sole discretion. ILLC will work with Subscribers to customize such parameters thereby allowing Subscribers to tailor the amount and frequency in which they receive Activity Alerts. For example, Subscribers who have requested to receive no more than a certain number of Activity Alerts during a predetermined time period (e.g., over the course of one day) would not receive additional Activity Alerts once that threshold has been met. ILLC will implement such requests in its sole direction.
Institutional clients (i.e., non-broker-dealer Subscribers) may elect to only interact with trading interest of other institutional Subscribers in confirm mode. This counterparty permissioning functionality is not available to broker-dealer Subscribers.
Subscribers that elect to use the Front End in conjunction with the Desktop Application may manually acknowledge a Preliminary Match in confirm mode, while other Subscribers may only use confirm mode by electing to use functionality whereby the order will automatically and immediately accept all Preliminary Matches in confirm mode. 

BlockCross does not perform an opening or reopening cross. BlockCross opens for trading on a security-by-security basis. Trading in a security begins once BlockCross has received a last sale eligible print in a security, during regular market hours, as reported by the SIP. Once BlockCross receives a last sale eligible print in a security, BlockCross applies the standard prioritization, matching, and execution rules noted in Part III Item 11(c).

BlockCross will accept orders beginning at 2:00 am. For priority purposes, an order's receipt time is the actual time of receipt by the ATS, regardless of whether an order is received prior, or during, regular trading hours (e.g., an order received at 2:30 a.m. ET has priority over an order received at 6:00 a.m. ET, and both orders have priority over an order received at 9:45 a.m. ET).

When BlockCross has received a notice that a security is subject to a regulatory halt, BlockCross automatically halts trading in the security. BlockCross does not cancel open order interest and continues to accept orders in a halted security. Order time of receipt, for priority purposes, is the time the order was actually received by the BlockCross system, and is not impacted by a trading halt (unless the trading halt delays BlockCross' receipt of the relevant order). BlockCross will resume trading in the security once it receives notice that the regulatory halt has been lifted.

Activity Alerts are not generated until the security has opened for trading on BlockCross. Subscribers may generate Subscriber Generated IOIs, and receive Agency IOIs even if the security has not opened for trading on BlockCross. 

BlockCross maintains a specific price priority regardless of whether the order is received pre-open. As noted above, orders received during or prior to a trading halt are not cancelled and BlockCross uses their actual time of receipt for order priority purposes. Following lifting of a trading halt, orders are matched in accordance with BlockCross' standard order matching logic and priority. See Part III Item11(c). 

BlockCross is a crossing system which allows Subscribers to enter orders in equity securities for prioritization and interaction with orders of other BlockCross Subscribers. BlockCross matches orders on a continuous basis during its hours of operation. All NMS Stocks are eligible for trading on BlockCross. The systems related to the ATS support multiple trading modes (see Part III, Item 11(c)), conditional orders, IOIs, and Activity Alerts (see Part III, Item 9), as well as order routing functionalities that allow Subscribers to seek contra-side interest for their trading interest in other market centers while simultaneously exploring matching opportunities in BlockCross (see Part III, Item 5).

ILLC offers BlockCross Subscribers the ability to integrate the Subscriber's order book (in whole or in part) via blotter integration. Blotter integration is an automated solution that allows a Subscriber to copy and continuously and automatically "synchronize" all or a designated portion of its order blotter into the Front End. Other than the functionalities described in response to Part III, Items 9,11, and 15, orders are not displayed. 

Only institutional Subscribers and broker-dealer Subscribers acting in an agency capacity may transmit Subscriber Generated IOIs. Only institutional clients that use the BlockCross Desktop Application may receive Subscriber Generated IOIs.

Only ILLC may send Agency IOIs. Only those ATS Subscribers that have elected to download and use versions of the BlockCross Desktop Application that include the IOI functionality (Subscribers may choose to continue to use certain legacy versions of the Desktop Application where this functionality was not in operation) and that have opted in to receiving IOIs in this manner may receive Agency IOIs.

Only users of the BlockCross Desktop Application may receive Activity Alerts.

Activity Alerts are automatically generated by the Front End from time to time throughout the trading day in accordance with parameters set by ILLC in its sole discretion. ILLC will work with Subscribers to customize such parameters thereby allowing Subscribers to tailor the amount and frequency in which they receive Activity Alerts. For example, Subscribers who have requested to receive no more than a certain number of Activity Alerts during a predetermined time period (e.g., over the course of one day) would not receive additional Activity Alerts once that threshold has been met. ILLC will implement such requests in its sole direction.

Institutional clients (i.e., non-broker-dealer Subscribers) may elect to only interact with other institutional Subscribers in Confirm Mode. This counterparty permissioning functionality is not available to broker-dealer Subscribers. 

ORDER INTERACTION: Orders submitted in any trading mode, whether committed or uncommitted, are executed based on time priority, marketability and in accordance with the order's designated trading mode and any Subscriber-selected counterparty restrictions (i.e. for priority purposes, the ATS does not differentiate between orders based on trading mode or whether the order is committed or uncommitted).

There is no "tiering" of Subscribers for matching and execution purposes in BlockCross and marketable orders are executed based on time priority. Subscribers within a particular class (e.g., broker-dealer or institutional) do not receive matching and execution priority as compared to Subscribers in another class, and all trading modes receive the same execution priority. Where an order has been submitted in both AutoEx and Confirm modes (i.e., the order is eligible for execution under either mode), the order will first match in AutoEx mode in the event the eligible contra-party interest with highest time priority exists in both modes.

Orders will match where both orders are eligible to execute at the midpoint of the NBBO or at a price within the NBBO spread. If two or more orders with eligible limit prices have the same symbol and side, priority is given to the order deemed by BlockCross to have been received first. BlockCross does not permit the execution of orders when the NBBO is locked or crossed.

BlockCross currently supports the following reference prices for pegged orders (see Part III, Item 7): (1) Last Executed Price; (2) Volume Weighted Average Price; (3) Midpoint; (4) Market; and (5) Primary. Such orders will become eligible to execute when the reference price to which the order is pegged falls within the NBBO. The ATS does not adjust the time of receipt of pegged orders to account for reference price changes.

If any order submitted for execution to BlockCross remains unexecuted or only partially executed at any time during the trading day, those orders remain in BlockCross until the earlier of: (a) their full execution in BlockCross; (b) the end of the relevant trading day; (c) the Subscriber cancels the order; (d) with respect to "uncommitted" orders, the ATS is notified that the underlying shares of the order were executed in another trading venue, (e) the Subscriber fails to confirm a System Match in the confirm trading mode; (f) the Subscriber receives notification of a System or Preliminary Match under the relevant trading mode with respect to an uncommitted order and the Subscriber's system fails to indicate that a sufficient quantity of the shares are available to execute the match; (g) in the event that the connectivity between the Subscriber's systems and the ATS or Front End, as applicable, is disconnected or (h) the Subscriber logs out of or is otherwise disconnected from the BlockCross Desktop Application, unless the relevant Subscriber has provided a separate standing written instruction to BlockCross indicating this event should not result in the removal of any orders from BlockCross. If the size of a partially executed order is below the system's relevant minimum trade quantity (see Part III, Item 8), the order will remain in BlockCross as an order ineligible for execution until the Subscriber either cancels the order, adds sufficient shares to make the order eligible for matching and execution or the order otherwise expires at the end of the trading day.

COMMITTED AND UNCOMMITTED ORDERS: Uncommitted orders are not executed on BlockCross until BlockCross has verified that the Subscriber's shares are still available. Committed orders are available for matching and execution with other committed orders as well as uncommitted orders, so long as both orders have been submitted in the same trading mode. The ATS will attempt to verify uncommitted trading interest, following an initial match in either trading mode. The verification is an automated, system-to-system messaging process wherein the ATS communicates directly with a Subscriber's OMS/EMS system via FIX connection. The ATS has the ability to use other message types, as may be required by a Subscriber's systems. The verification process generally takes approximately 4.5 seconds. If after 4.5 seconds the Subscriber's system has not responded, the ATS will consider the shares unavailable.

TRADING MODES: Generally, trading interest submitted in AutoEx mode may be executed without further instruction from the Subscriber. The ATS must confirm the availability of any "uncommitted" shares submitted in AutoEx mode prior to execution. Trading interest submitted in Confirm mode must be confirmed or "firmed-up" prior to execution (such confirmation separate from confirming the availability of any uncommitted shares). Subscribers utilizing the Desktop Application may utilize both AutoEx and Confirm Modes to manually manage their trading interest in the Front End. Subscribers that do not utilize the Desktop Application may submit orders in AutoEx mode but must, to the extent they wish to utilize Confirm mode, establish a standing instruction to automatically and immediately accept all Preliminary Matches for their orders submitted in Confirm mode.

Orders submitted in AutoEx mode are available for matching and execution with other orders submitted in AutoEx mode but are not eligible for matching with orders submitted in Confirm mode. Orders submitted in Confirm mode are available for matching and execution with other order submitted in Confirm mode but are not eligible for matching with orders AutoEx mode.

AUTOEX MODE: Subscribers submitting orders in AutoEx mode may select any available pricing instructions (see Part III, Item 7), an ultimate limit price, and may designate a minimum quantity. In AutoEx mode, a committed order will be executed automatically when eligible committed contra-side interest is identified. Following a match where one or both sides of the match are uncommitted, the ATS must first verify that the uncommitted shares are still available ("Preliminary Match").

Following a Preliminary Match, and during the verification process, neither an uncommitted order nor a committed order will be available for other matching opportunities in the ATS.

After a Preliminary Match and after the ATS has completed the verification process, the following may occur: (1) Shares underlying the uncommitted order are available: The ATS will convert the uncommitted order to a committed order and, to the extent eligible committed contra-side interest remains available, the order is automatically executed in BlockCross. In the event the contra-side interest is no longer available, the match will not result in an execution and the initially uncommitted order will be converted back to an uncommitted order and will retain its original priority; (2) Shares underlying an uncommitted order are unavailable: The uncommitted order will not be converted to a committed order, the match will not result in an execution, and the uncommitted order will be cancelled; (3) Both sides available but match and execution result in a partial fill: If the match and execution result in a partial fill of the Subscriber's formerly uncommitted order, the remaining shares retain the designation of committed in BlockCross for a limited time to allow the system to seek other matching opportunities. This period of time generally takes no more than five seconds from the time of the Subscriber's last execution and is reset following each execution for a maximum of 45 seconds. In each case, following the release of any shares underlying a committed order, the order associated with those shares returns to the status of uncommitted in BlockCross ATS and retains its original time priority status.

BlockCross will price all AutoEx-mode orders at the midpoint of the NBBO at the time of automatic execution.

AutoEx-mode orders that are pegged to a reference price will execute only where the midpoint is: (i) for buy orders, equal to or lower than the pegged price at the time of execution; or (ii) for sell orders, equal to or higher than the pegged price at the time of execution. No execution will take place where the midpoint is: (i) higher than the pegged price for buy orders; or (ii) lower than the pegged price for sell orders.

ACTIVITY ALERTS: In the event a Subscriber receives an Activity Alert (see Part III, Item 9) a message will appear on the Subscriber's Desktop Application alerting the Subscriber of potential contra-side activity in the Front End. Activity Alerts display the symbol and side of the orders and do not display the size of the order or the identity of the potential counter party. Upon receiving the Activity Alert, each Subscriber may accept or reject the notification. In the event both Subscribers accept, each Subscriber will receive a pop-up on their Desktop Application that will allow each Subscriber to enter a quantity and limit price at which they are willing to trade. If after this process the match is eligible for execution, the order will execute in accordance with the process listed above. If after this process the match is ineligible for execution, no execution will occur and each order retains its original priority as well as its original price and size conditions. In the event one or both of the Subscribers reject the Activity Alert, no match will occur and each order retains its original priority as well as its original price and size conditions.

CONFIRM MODE: Confirm mode allows Subscribers to submit conditional order interest that Subscribers must confirm or "firm-up" prior to any execution (such confirmation separate from verifying the availability of any uncommitted shares). Subscribers submitting orders or trading interest in Confirm mode may select any available pricing instructions (see Part III, Item 7) and set an ultimate limit price. In the event the Front End identifies a natural trading opportunity (e.g. the pricing instructions for both sides have been met and the orders are eligible for trading), both the buyer and the seller will receive notification of the potential trading opportunity ("System Match"). The notification received will identify the symbol and side of the trading opportunity and allow the Subscriber to enter the amount of shares they are willing to trade.

The execution of an order in Confirm mode requires both Subscribers to a potential transaction to acknowledge a System Match (i.e., authorize the execution of their orders) within thirty seconds of the System Match. Once a Subscriber has been notified of a System Match, the order subject to that match becomes unavailable for other matching opportunities in the ATS during the "firm-up" period (see also Part III, Item 9). Subscribers that use the BlockCross Desktop Application may manually confirm a match. Additionally, Desktop Application users may establish a standing instruction to either (i) automatically accept, at the end of the thirty second confirmation time period, any System Matches under Confirm mode that the Subscriber has not otherwise manually rejected or accepted or (ii) automatically and immediately accept all System Matches under Confirm mode. Subscribers that do not utilize the Desktop Application must, to the extent they wish to utilize Confirm mode, establish a standing instruction to automatically and immediately accept all System Matches.

If a Subscriber on either side of a potential trade in Confirm trading mode fails to affirmatively acknowledge a match within the allotted thirty-second confirmation time period described above then no execution will result from the System Match. Further, where a Subscriber fails to affirmatively acknowledge a System Match within the thirty second confirmation time period, that Subscriber's order will be removed from the ATS, along with any other orders from that Subscriber with the same symbol and side.

If a Subscriber affirmatively acknowledges a System Match in circumstances where the other Subscriber to a potential trade does not, the Subscriber acknowledging the System Match will receive a message indicating that the match has timed out, although its order will not be cancelled and will retain its original time priority status.

As noted above, Subscribers may submit uncommitted orders in Confirm Mode. In Confirm Mode, if a Subscriber integrates with the ATS through blotter integration, its order will always be designated as uncommitted, unless the Subscriber then elects to set all or a portion of the order as an AutoEx order.

By default, the ATS will request the shares underlying an uncommitted order before notifying both parties of the match. If the shares are available, then the ATS will convert the order to a committed order for the duration of the match and notify both parties of the match. However, Subscribers that use the Desktop Application in conjunction with blotter integration may elect that the verification and conversion of an uncommitted order be delayed until the Subscriber has acknowledged a confirm match.
As noted above, Subscribers that do not use the Desktop Application cannot manually acknowledge a System Match and may only use Confirm Mode by electing to use a standing instruction to automatically and immediately accept all System Matches in Confirm Mode. Separately, only Subscribers that use the Desktop Application in conjunction with blotter integration may elect that the conversion of an uncommitted order be delayed until the acknowledgment of a Confirm Match.

CONFIRM (BUYER RESPONDS FIRST): When two orders are eligible to match at the midpoint of the NBBO, BlockCross captures the midpoint of the NBBO at the times that each of the buyer and seller affirmatively acknowledge a match and prices and executes all orders at the lower of these two midpoints. However, if the lower of these two midpoints is no longer within the NBBO at the time of order print, the execution price will be increased to the best (i.e., highest) available bid price at the time of order print (if such bid is higher than the lower of these two captured midpoints at such time) or decreased to the midpoint of the NBBO at the time of order print (if the best offer at the time of order print is lower than the lower of these two captured midpoints). Additionally, if the ATS cannot effect a transaction at a designated execution price (as described above) no transaction will occur (that is, the ATS will NOT effect a transaction at the closest eligible execution price).

CONFIRM (SELLER RESPONDS FIRST): When two orders are eligible to match at the midpoint of the NBBO, BlockCross ATS captures the midpoint of the NBBO at the times that each of the buyer and seller affirmatively acknowledge a match and prices and executes all orders at the higher of these two midpoints. However, if the higher of these two midpoints is no longer within the NBBO at the time of order print, the execution price will be increased to the midpoint of the NBBO at the time of order print (if the best bid at the time of order print is higher than the higher of these two captured midpoints at such time) or decreased to the best (i.e., lowest) available offer price at the time of order print (if such offer is lower than the higher of these two midpoints). Additionally, if the ATS cannot effect a transaction at a designated execution price (as described above) no transaction will occur (that is, the ATS will NOT effect a transaction at the closest eligible execution price).

PRICE PROTECTION: Confirm mode offers an optional "price protection" feature in Confirm Mode to mitigate the impact of price movement during the thirty second confirmation time period. This feature is a default functionality of BlockCross, but Subscribers may affirmatively elect to have it deactivated for their confirm mode trades. The price protection feature calculates a standardized maximum and standardized minimum allowable trade execution price for each of the buyer and seller, respectively, based on criteria (e.g., spreads that vary based on range of publicly traded price of the underlying security) set by BlockCross in its sole discretion. If the actual trade execution price, as calculated above, would violate these maximum or minimum prices, there will be no trade. See Exhibit 3.

SHORT SALES: BlockCross is designed to operate in compliance with the requirements of Reg. SHO when accepting or executing orders. Accordingly, once a circuit breaker has been triggered, the Rule 201 price test restriction will apply to short sale orders in that security for the remainder of the day and the following day, unless an exemption applies. BlockCross will only accept orders marked "short exempt" from broker-dealer Subscribers.

EXECUTION ERRORS: For bona fide errors (as defined in FINRA Rule 6191) and other general errors made by ILLC or a client, ILLC handles execution errors occurring within the ATS in accordance with the Firm's internal policies and procedures (the "Error Procedures").
The Error Procedures require that a relevant Principal or delegate be notified of any error occurring within the ATS. For general errors (e.g., technology, administrative) ILLC will determine the best course of action, including cancelling both sides of the erroneous trade, based on internal policy and, on a case-by-case basis, the facts and circumstances of each error. ILLC handles executions at clearly erroneous prices in accordance with the applicable rules of the SRO, including FINRA Rule 11891.. Following a determination of erroneous trading by the primary market, ILLC will cancel both sides of any erroneous trade. 

See response to Part III, Item 11(b). 

SEGMENTATION BASED ON SUBSCRIBER TYPE: BlockCross categorizes Subscribers as either (x) broker-dealer or (y) institutional firms. Categorization is performed at the Subscriber level (i.e., BlockCross does not look through the Subscriber to the identity of any underlying order flow). All Subscriber registered with the SEC as broker-dealers are included in the "broker-dealer" category, and all other Subscribers are included in the "institutional" category. Notwithstanding the foregoing, Subscribers may instruct ILLC to identify orders submitted via an Instinet Algorithm as originating from the Subscriber.

Subscribers of BlockCross may use two modes for executing orders: (1) AutoEx and (2) Confirm. Subject to the ability of a Subscriber to opt out of matching with its affiliates, all orders submitted by a Subscriber for execution under the AutoEx trading mode are subject to matching with orders of any other Subscriber submitted in that same trading mode. Institutional Subscribers are able to limit the class of Subscribers with whom their orders will interact in Confirm mode. Specifically, institutional Subscribers may designate that all orders submitted for execution in Confirm mode may only match with orders submitted by other institutional Subscribers. Institutional/broker-dealer categorization does not otherwise impact order interaction. Such an election is made by the Subscriber and will remain in force until the Subscriber directs ILLC to remove the election. ILLC does not override such elections.
Separately, only institutional Subscribers and broker-dealer Subscribers acting in an agency capacity may transmit Subscriber Generated IOIs. Only institutional clients that use the Desktop Application may receive Subscriber Generated IOIs.

SEGMENTATION BASED ON ACTIVITY: Subscribers who have submitted orders or trading interest to the Front End system may receive Activity Alerts (See Part III, Item 9).
Activity Alerts are automatically generated by the Front End from time to time throughout the trading day in accordance with algorithmic parameters set by ILLC in its sole discretion, which parameters consider, among other things, the aggregate number of activity alerts sent out by the Front End during the trading day and the type of response by the relevant Subscriber to Activity Alerts in the same symbol sent earlier in the trading day. Specifically, a Subscriber that affirmatively rejects an Activity Alert or affirmatively accepts an Activity Alert but ultimately does not submit an order to BlockCross in response to that activity alert is less likely to receive another Activity Alert in that same security than a Subscriber that took no action whatsoever in response to the Activity Alert.
Note, this functionality does not impact orders and trading interest submitted in Confirm Mode, nor does it impact whether orders and trading interest submitted in AutoEx mode will match and execute with contraside AutoEx trading interest outside of the Activity Alert functionality. 

During the standard onboarding process for all potential ILLC clients, clients provide certain information and documentation that confirms each client's classification (e.g. Form BD submitted during the onboarding of a broker-dealer client). As discussed in Part III, Item 13(a), available functionality is dependent upon the Subscriber's classification. Generally, the functionalities offered to each Subscriber classification are discussed with each Subscriber during the onboarding process and all clients may request additional information regarding the products, services, and related features as necessary. 

Institutional Subscribers may elect to only interact with other institutional Subscribers in confirm mode. This functionality is not available in AutoEx Mode. All Subscribers may elect to not interact with one or more of their affiliates in any trading mode. 

Only institutional Subscribers may elect to only interact with other institutional Subscribers in confirm mode; such counterparty permissioning functionality is not available to broker-dealer Subscribers. 

All orders submitted to BlockCross pass through the Front End system. Where an order passes through the Front End, including where a previously submitted order is modified, the terms of such order, including the identity of the Subscriber submitting the order, are displayed to the Front End. The Front End also receives messages indicating when an order has been executed in the ATS (in whole or in part) and where an order has been cancelled (in whole or in part). Additionally, the Front End receives messages related to the status of conditional trading interest, including: (1) where an uncommitted order has been changed to a committed order; (2) System Matches of trading interest (e.g., requests to "firm up" in Confirm Mode) and Subscriber responses; (3) Preliminary Matches of trading interest submitted in AutoEx Mode and Subscriber responses (e.g. matches involving uncommitted orders).

ACTIVITY ALERTS: Activity Alerts display only symbol and side of the contra-side interest and are only received by Desktop Application Users. Activity Alerts are only displayed to BlockCross Subscribers.

CONFIRM MODE: System Matches of trading interest (e.g., requests to "firm up" in Confirm Mode) display only symbol and side of the contra-side interest and are only received by Desktop Application Users. System Matches are only displayed to BlockCross Subscribers and remain displayed for no more than 30 seconds.

SUBSCRIBER GENERATED IOIS: Subscriber Generated IOIs are displayed to the market participants listed in Part III, Item 9 and to BlockCross Subscribers utilizing the Desktop Application. Subscriber Generated IOIs are displayed as "BLKX" on Bloomberg and NYSE's ioinet and include symbol and side but the identity of the Subscriber sending the IOI is not displayed. IOIs received by Subscribers utilizing the Desktop Application display only symbol and side. Subscribers may elect to send an IOI once, or may elect to have the system resend the IOI , at intervals that must be at least 30 minutes long.

AGENCY IOIS: The Agency IOI functionality does not allow for any Subscriber name, order or trade position information to flow from the Front End to the ILLC agency trading desk. However, as described in response to Part III, Item 9, the ILLC agency trading desk is aware of the identity of Subscribers that are eligible to receive Agency IOIs. Subscribers will remain eligible to receive Agency IOIs unless the Subscriber elects to no longer receive such IOIs.

Subscribers receiving an Agency IOI would receive a "pop-up" message on their Desktop Application alerting the Subscriber to the trading opportunity. The "pop-up" message displays to the receiving Subscriber symbol, side, and size of the trading opportunity.

Other than the functionalities described above and in response to Part III, Items 9 and 11, orders are not displayed. 

Subscribers may route orders through the Front End to the ATS and to other market centers, including other alternative trading systems operated by ILLC. Subscribers may elect to represent in the ATS, on a conditional basis, firm trading interest that the Subscriber has routed to another market center (i.e., submit an uncommitted order to the ATS where "firm" trading interest is submitted to another market center).

Where eligible contra-side interest exists, the ATS will request that the Front End "confirm" an uncommitted order in the ATS. Following the execution, or attempted execution, of the committed shares, the ATS will thereafter release any unexecuted shares back to the Front End. Thereafter, the Subscriber may elect to route those shares to another market center, including other alternative trading systems operated by ILLC. However, the ATS will retain an uncommitted order representing the released shares. All decisions to route orders or trading interest away from the ATS are made by the Subscriber by making such elections on an order-by-order basis on the Desktop Application. The ATS is not involved in any routing determinations. 

ILLC charges Direct Subscribers to BlockCross on a per share basis. ILLC does not charge Subscribers access fees (e.g. monthly access fees, hookup fees, port fees, or connection fees). Fees charged for executions within BlockCross are not standardized.

For Direct Subscriber order flow to BlockCross, Subscribers are charged a commission in the range of $0 - $0.02 per share for executions in BlockCross.
The fee associated with BlockCross may vary within the ranges above based on the Direct Subscriber's trading volume and or the level of service required by each client, including, but not limited to, whether a client will utilize ILLC execution services, research services, analytics tools, Instinet Instinet Algorithms, or OMS/EMS systems. Additionally, the level of custom modifications to each product requested by the client may impact pricing. 

Fees charged for Indirect Subscriber order flow (orders and trading interest routed by an Instinet Trading Product or submitted to an Instinet Trading Desk for further handling and execution) are not standardized and are individually negotiated.
Instinet generally operates under two pricing models, All-In and Cost Plus. Clients utilizing the All-In pricing model would pay an agreed upon per-share commission regardless of destination. ILLC may charge a commission in the range of $0.0001 - $0.10.
Clients utilizing the Cost Plus model would pay the cost of execution plus commission (e.g. client would pay $0 - $0.02 per share for executions in BlockCross plus that client's individually negotiated commission).
The variables that impact pricing include the expected trading volume of the client and the level of service required by each client, including, but not limited to, Subscriber clearing type, whether a client will utilize ILLC execution services, research services, analytics tools, Instinet Algorithms, or OMS/EMS systems. Additionally, the level of custom modifications to each product requested by the client may impact pricing.
Each client's category (broker-dealer or institutional) is not considered in each such clients commission rates. 

BlockCross does not offer rebates or discounts to Subscribers. 

The BlockCross system operator can halt trading during periods when the system is not operating as expected. BlockCross may suspend trading for technology or compliance related reasons. Matching can be paused where new orders will continue to be accepted and prioritized as they would during normal trading without any matching taking place. BlockCross also has the ability to reject all new orders should situations dictate. Once the pause is lifted, trading will begin in each security with the first quote update that appears on the consolidated tape.

ILLC trading desk personnel provide clients notice of a suspension or stoppage in trading on an as needed basis. Clients may request that notice of a suspension or stoppage of trading be provided.
BlockCross may suspend trading for individual NMS stocks with a symbology update.

The ATS Principal monitors activity on the ATS for compliance with Reg. ATS and SCI, including whether, during at least four of the last six months, it had with respect to NMS stocks (i) 5% or more in any single NMS stock, and 0.25% or more in all NMS stocks, of the average daily dollar volume reported by an effective transaction reporting plan, or (ii) 1% or more, in all NMS stocks, of the average daily dollar volume reported.

If the ATS had 0.25% or more of the average daily dollar volume reported by an effective transaction reporting plan in all NMS stocks, and an individual security has breached the 5% threshold in three out of six months, the symbol will be set to "route only" mode. The "route only" mode will prevent the Instinet Trading products from routing the symbol to the ATS. Orders in such a symbol routed to the ATS via third-party algorithms, smart routers, or otherwise will be rejected.

When the 1% threshold for all NMS stocks is breached for the first, second, and third time in a six month span, ILLC may take a range of action, in its sole discretion. 

Clients may request that notice of a suspension or stoppage of trading be provided. Those clients who have requested such notice will be notified as soon as practicable. Clients who have not requested notice of a suspension or stoppage of trading may be provided notice on an as needed or as necessary basis. 

ILLC reports all equities transactions executed in BlockCross to the FINRA/NASDAQ Trade Reporting Facility (TRF) located in Carteret. 

ILLC is a self-clearing broker and a member of the National Securities Clearing Corporation ("NSCC") and the Depository Trust Company ("DTC"). ILLC becomes a counterparty to each side of any transaction executed on the ATS. ILLC does not custody funds or securities for Subscribers and settles all transactions effected on the ATS with the Subscriber or the Subscriber's custodian, prime broker or other settlement agent, in accordance with settlement instructions provided by the Subscriber to ILLC. For Subscribers settling via the facilities of the NSCC, ILLC submits each transaction to the NSCC for clearance (either for trade matching with the NSCC member contra or on a locked-in basis, such as through a Qualified Special Representative arrangement), with the legal obligation for settlement of the transaction transferring from ILLC to NSCC once NSCC has novated the submitted transaction and final settlement through the facilities of the DTC. For Subscribers settling via the facilities of the DTC, ILLC submits transaction information to OMGEO or DTC for affirmation prior to final settlement via the facilities of the DTC.

ILLC utilizes certain Broadridge Financial Solutions, Inc. systems and services for the purposes of recordkeeping, clearance and trade settlement processing. 

BlockCross consumes the Securities Information Processor feed (SIP) for matching purposes as well as for Activity Alerts, Subscriber Generated IOIs, and Agency IOIs. The SIP data feeds are combined by an ILLC market data consolator that sits outside of the ATS and calculates a consolidated NBBO based on the SIP. The ATS utilizes the NBBO to price, prioritize and execute orders as described in Part III, Item 11.

The ATS is designed to operate in compliance with all applicable rules and regulations (e.g., Reg NMS, Reg SHO, etc.). The ATS can also use market data from the SIP to interpret any condition disseminated by the marketplace (e.g. Limit Up/Limit Down bands).
