Subscriber and Sponsored Participant orders that are placed in the UBS ATS will have an opportunity to interact with UBS BD’s US equity order flow – liquidity that includes client agency order flow, including Direct Market Access (“DMA”) and algorithmic trading, and principal order flow from UBS BD trading desks. In addition, Subscriber orders will interact with orders from other Subscribers. Orders routed to and received by the UBS ATS are not routed out to any other market center. 2.1 Hours of Operation Please see Section 2.1 in Exhibit F of our Form ATS filing for details on Hours of Operation. 2.2 Eligible Stocks All NMS Stocks, unless otherwise specified. UBS ATS publishes a monthly list of symbols that it will not trade. Orders sent for symbols on this list will be rejected. Please email OL-UBSATS-SUPPORT@ubs.com with a request to be added to this email distribution list. UBS ATS will accept, but not execute, production test symbols such as ZVZZT. 3 Order Types Please see Section 2.2 in Exhibit F of our Form ATS filing for details on Order Types. 4 Order Entry 4.1 Minimum Quantity Orders may be routed to the UBS ATS with a minimum quantity value specified. UBS ATS will only cross where at least this number of shares is available from a single eligible contra side order. 4.2 Maximum Quantity The UBS ATS will enforce a maximum order size equal to 50% of the stock’s ADV, per order, subject to change. All orders are subject to risk checks in compliance with SEC Rule 15c3-5. 4.3 Routing Restrictions Please see Section 3.1 in Exhibit F of our Form ATS filing for details on Routing Restrictions. 4.4 Crossing Restrictions Please see Section 3.3 in Exhibit F of our Form ATS filing for details on Crossing Restrictions. 4.5 Notification of Crossing Restrictions Please see Section 3.4 in Exhibit F of our Form ATS filing for details on Notice of Crossing Restrictions. 4.6 Short Sale Orders Please see Section 3.5 in Exhibit F of our Form ATS filing for details on Short Sale Orders. 1 4.7 Availability UBS reserves the right to temporarily disconnect Subscribers due to technology issues either with the UBS ATS, a Subscriber, or within the UBS BD.
