Re:
SEC v. Binance Holdings Limited, et al. (1:23-cv-01599)
Dear Counsel:
In an effort to narrow the issues in dispute consistent with the Court’s recommendations at
the September 18, 2023 hearing, attached are requests for specific documents and communications
that fall within the SEC’s June 23, 2023 Requests for Production. (See Attachment A). We have
included representative citations to deposition transcripts where applicable. As previously
discussed, please also provide updated certified interrogatory responses, including those set forth
in the Proposed Order to the SEC’s Motion to Compel. (See Dkt. 102, Proposed Order at ¶ 8.)
Please complete your production of these materials, consistent with the SEC’s data delivery
standards by October 6, 2023. We are open to discussing an expedited timeline for production of
these materials, but many of the documents should be readily identifiable, having already been
identified in deposition or our prior discussions. As the Court noted at the hearing this week, a
more complete production prior to depositions will best facilitate the examination of the deponents
and help avoid having to call witnesses back because of subsequent productions.
In addition, as requested in my September 19 email, please provide available dates for inperson depositions in Washington, D.C. for the individuals listed below, preferably in the order
they are identified. For certain individuals, we are open to discussing scheduling more than one
deposition on a given day and remote options.

We welcome the opportunity to meet and confer regarding the scope and time allotment
for the 30(b)(6) deposition. As discussed, we believe such deposition testimony on the identified
topics would be an efficient and effective way to address many of the key issues and may alleviate
the need for, or at least help streamline, the depositions of some of the other individuals.
We reserve our rights to amend or add requests or notice additional depositions.
We appreciate your prompt attention to this matter. Feel free to contact us with any
questions or concerns.
Respectfully,
