          - [Release No. 34-98303; File No. 4-546]

                    Pursuant to Section 11A(a)(3) of the Securities Exchange Act of 1934                           ( print page 62611)                        (“Act”) [1]                                          and Rule 608 thereunder,[2]                                          notice is hereby given that on August 29, 2023, MEMX, LLC (“MEMX” or “Exchange”) filed with the Securities and Exchange Commission (“Commission”) an amendment to the Options Order Protection and Locked/Crossed Market Plan (“Plan”).[3]                                          The amendment adds MEMX as a Participant [4]                                          to the Plan. The Commission is publishing this notice to solicit comments on the amendment from interested persons.                

## I. Description and Purpose of the Amendment

                    The Plan requires the options exchanges to establish a framework for providing order protection and addressing locked and crossed markets in eligible options classes. The amendment to the Plan adds MEMX as a Participant. The other Plan Participants are BATS, BOX, BX, C2, CBOE, EDGX, Emerald, ISE, ISE Gemini, ISE Mercury, MIAX, Nasdaq, Pearl, Phlx, NYSE MKT, and NYSE Arca. MEMX has submitted an executed copy of the Plan to the Commission in accordance with the procedures set forth in the Plan regarding new Participants. Section 3(c) of the Plan provides for the entry of new Participants to the Plan. Specifically, Section 3(c) of the Plan provides that an Eligible Exchange [5]                                          may become a Participant in the Plan by: (i) executing a copy of the Plan, as then in effect; (ii) providing each current Participant with a copy of such executed Plan; and (iii) effecting an amendment to the Plan, as specified in Section 4(b) of the Plan.[6] 

Section 4(b) of the Plan sets forth the process by which an Eligible Exchange may effect an amendment to the Plan. Specifically, an Eligible Exchange must: (a) execute a copy of the Plan with the only change being the addition of the new Participant's name in Section 3(a) of the Plan; and (b) submit the executed Plan to the Commission. The Plan then provides that such an amendment will be effective when the amendment is approved by the Commission or otherwise becomes effective pursuant to Section 11A of the Act and Rule 608 thereunder.

## II. Effectiveness of the Proposed Linkage Plan Amendment

                    The foregoing Plan amendment has become effective pursuant to Rule 608(b)(3)(iii) [7]                                          because it has been designated as involving solely technical or ministerial matters. At any time within sixty days of the filing of this amendment, the Commission may summarily abrogate the amendment and require that it be refiled pursuant to paragraph (a)(1) of Rule 608,[8]                                          if it appears to the Commission that such action is necessary or appropriate in the public interest, for the protection of investors, or the maintenance of fair and orderly markets, to remove impediments to, and perfect the mechanisms of, a national market system or otherwise in furtherance of the purposes of the Act.
