No Options Participant or person associated with an Options Participant shall circulate, in any manner, rumors of a character which might affect market conditions in any security; provided, however, that this Rule shall not prohibit discussion of unsubstantiated information, so long as its source and unverified nature are disclosed.

Adopted October 23, 2019 (SR-BX-2019-039).

(a) Every Options Participant shall establish, maintain and enforce written policies and procedures reasonably designed, taking into consideration the nature of the Participant's business, to prevent the misuse of material nonpublic information by such Participant or persons associated with such Participant in violation of the federal securities laws or the Rules thereunder, and the Rules of the Exchange.

(b) Misuse of material nonpublic information includes, but is not limited to:

(1) trading in any securities issued by a corporation, or in any related securities or related options or other derivative securities, while in possession of material nonpublic information concerning that corporation;

(2) trading in an underlying security or related options or other derivative securities, while in possession of material nonpublic information concerning imminent transactions in the underlying security or related securities; and

(3) disclosing to another person any material nonpublic information involving a corporation whose shares are publicly traded or disclosing an imminent transaction in an underlying security or related securities for the purpose of facilitating the possible misuse of such material nonpublic information.

(1) All associated persons must be advised in writing of the prohibition against the misuse of material nonpublic information.

(3) Records of all brokerage accounts maintained by the Participant and all associated persons must be acquired and maintained for at least three (3) years, the first two (2) years in an easily accessible place, and such brokerage accounts must be reviewed periodically by the Participant for the purpose of detecting the possible misuse of material nonpublic information.

(4) Any business dealings the Participant may have with any corporation whose securities are publicly traded, or any other circumstances that may result in the Participant receiving, in the ordinary course of business, material nonpublic information concerning any such corporation, must be identified and documented.

(d) Participants that are required to file Form X-17A-5 under the Exchange Act or Rules thereunder, with the Exchange on an annual basis only, shall, contemporaneously with those submissions, file attestations signed by such Participants stating that the procedures mandated by this Rule have been established, enforced and maintained.

(e) Any Options Participant or associated person who becomes aware of any possible misuse of material nonpublic information must promptly notify BX Regulation.

(f) It may be considered conduct inconsistent with just and equitable principles of trade for any Participant or person associated with a Participant who has knowledge of all material terms and conditions of:

(2) an order being facilitated or submitted to BX Options for price improvement, or

(3) orders being crossed;

the execution of which are imminent, to enter, based on such knowledge, an order to buy or sell an option for the same underlying security as any option that is the subject of the order, or an order to buy or sell the security underlying such class, or an order to buy or sell any related instrument until (a) the terms and conditions of the order and any changes in the terms and conditions of the order of which the Participant or person associated with the Participant has knowledge are disclosed, or (b) the trade can no longer reasonably be considered imminent in view of the passage of time since the order was received.

Adopted October 23, 2019 (SR-BX-2019-039).

Significant Business Transactions of Options Clearing Participants shall be governed by this Rule and not by BX Rule 1017. All other Significant Business Transactions of Options Participants shall be subject to BX Rule 1017.

(1) the combination, merger or consolidation between the Participant and another person engaged in the business of effecting, executing, clearing or financing transactions in securities or futures products;

(2) the transfer from another person, Market Maker, broker-dealer, or customer of securities or futures accounts that are significant in size or number to the business of the Participant;

(3) the assumption or guarantee by the Participant of liabilities of another person engaged in the business of effecting, executing, clearing or financing transactions in securities or futures products, in connection with a direct or indirect acquisition of all or substantially all of the person's assets; or

(4) termination of the Participant's clearing business or any material part thereof.

(b) Notification of any of the following SBTs shall be made in writing to BX Regulation, not later than five (5) business days from the date on which the SBT becomes effective:

(1) the sale by the Clearing Participant of a significant part of its assets to another person;

(2) a change in the identity of any general partner or a change in the beneficial ownership of ten percent (10%) or more of any class of the outstanding stock of any corporate general partner;

(3) a change in the beneficial ownership of twenty percent (20%) or more of any class of the outstanding stock of the Participant or the issuance of any capital stock of the Participant; or

(4) the acquisition by the Clearing Participant of assets of another person that would constitute a "business" that is "significant," as those terms are defined in Section 11-01 of Regulation S-X under the Exchange Act.

(c) A Clearing Participant is required to notify BX Regulation in writing thirty (30) days prior to a proposed SBT included in paragraph (a) of this Rule, and such SBT shall be subject to the prior approval of BX Regulation, if the Participant's Market Maker clearance activities exceed, or would exceed as a result of the proposed SBT, any of the following parameters:

(1) fifteen percent (15%) of cleared BX Options Market Maker contract volume for the most recent three (3) months;

(2) an average of fifteen percent (15%) of the number of BX Options Market Makers as of each month and for the most recent three (3) months; or

(3) twenty-five percent (25%) of BX Options Market Maker gross deductions (haircuts) defined by Rule 15c3-1(a)(6) or (c)(2)(x) under the Exchange Act carried by the Clearing Participant in relation to the aggregate of such haircuts carried by all other Clearing Participants for any month end within the most recent three (3) months.

(d) An SBT that comes within paragraph (c) of this Rule may be disapproved or conditioned within the thirty (30) day period if BX Regulation determines that such SBT has the potential to threaten the financial or operational integrity of Market Maker transactions. In making this determination, BX Regulation may consider, among other relevant matters, the following:

(1) The effect of the proposed SBT on the capital size and structure of the resulting Clearing Participant(s), the potential for financial failure and the consequences of any such failure on the BX Options market as a whole, and the potential for increased or decreased operational efficiencies arising from the proposed transaction.

(2) The effect of the proposed SBT upon overall concentration of Market Makers, including a comparison of the following measures before and after the proposed transaction:

(A) proportion of BX Options Market Maker contract volume cleared;

(B) proportion of BX Options Market Makers cleared; and

(C) proportion of Market Maker gross deductions (haircuts) as defined by Rule 15c3-1(a)(6) or (c)(2)(x) under the Exchange Act carried by the Clearing Participant(s) in relation to the aggregate of such deductions carried by other Participants that clear Market Maker transactions.

(3) The regulatory history of the affected Participants, specifically as it may indicate a tendency to financial or operational weakness.

(e) Transactions that come within paragraph (c) of this Rule shall be reviewed according to the following procedures:

(1) A Participant must provide promptly, in writing, all information reasonably requested by BX Regulation. Any information disclosed by Participants pursuant to the requirements of this Rule shall be kept confidential by BX Regulation until such information is otherwise publicly disclosed and shall be used only for purposes of reviewing the proposal.

(2) If BX Regulation determines, prior to the expiration of the thirty (30) day period, that a proposed SBT may be approved without conditions, BX Regulation shall promptly so advise the Participant.

(3) All decisions to disapprove or condition a proposed SBT or to impose extraordinary requirements shall be in writing, shall include a statement setting forth the grounds for the decision, and the Participant shall be promptly notified of any such decisions by BX Regulation.

(4) Notwithstanding any other provisions of the BX Options Rules, the Participant may appeal a decision to disapprove or condition a proposed SBT directly to the Board by filing an application for review with the Secretary of the Exchange within fifteen (15) days of the date of service of the decision. Appeal to the Board shall be the exclusive method of reviewing such a decision.

(5) An appeal to the Board of a decision to disapprove or condition a proposed SBT shall not operate as a stay of that decision during the pendency of the appeal.

(6) BX Regulation shall file notice with the SEC in accordance with the provisions of Section 19(d)(1) of the Exchange Act of all final decisions to disapprove or condition a proposed SBT.

(f) BX Regulation may impose additional financial and/or operational requirements on a Participant that clears Market Maker trades at any time when it determines that the Participant's continuance in business without such requirements has the potential to threaten the financial or operational integrity of Market Maker transactions.

(g) The provisions of this Rule do not preclude summary action under Chapter X, Discipline and Summary Suspensions, of these Rules, or other BX Regulation action pursuant to the BX Options Rules.

(h) BX Regulation, upon approval by the Chief Regulatory Officer of BX, may exempt a Participant from the requirements of this Rule, either generally or in respect of specific types of transactions, based on the limited proportion of Market Maker trades on BX Options that are cleared by the Participant or on the limited importance that the clearing of Market Maker trades bears to the total business of the Participant.

(a) Whenever it is determined from the reports of uncovered short positions submitted pursuant to Options 6E, Section 2 of these Rules (Reports of Uncovered Short Positions), viewed in light of current market conditions in options and in underlying securities, that there are outstanding an excessive number of uncovered short positions in options contracts of a given class traded on BX Options or that an excessively high percentage of outstanding short positions in options contracts of a given class traded on BX Options are uncovered, BX Regulation may determine to prohibit Options Participants from any further opening writing transactions on any exchange in options contracts of that class unless the resulting short position will be covered, and BX Regulation may prohibit the uncovering of any existing covered short positions in one or more series of options of that class, as it deems appropriate in the interest of maintaining a fair and orderly market in options contracts or in underlying securities.

(b) BX Regulation may exempt transactions of Options Market Makers from restrictions imposed under this Rule. Such restrictions shall be rescinded upon a determination that they are no longer appropriate.

Adopted October 23, 2019 (SR-BX-2019-039).

(B) in the case of a distribution being offered pursuant to rights, less than the amount by which the underwriters' stabilization bid in the underlying security at the subscription price exceeds the exercise price of such option.
