However, we also note your tabular disclosure on pages 152-153, which indicates that certain of your officers and directors currently serve on the board of the Fifth SPAC.

 loans. Also state the price at which the sponsor acquired the founder
shares. Finally,
 please provide a cross-reference, highlighted by prominent type or in
another manner,
 to the locations of related disclosures in the prospectus.
4. Where you discuss material dilution to your public shareholders, please
expand to
 state whether the cashless exercise of the private placement warrants,
the conversion
 of the working capital loans into warrants, and any other adjustments to
the number of
 Class B shares at the time of the offering or initial business
combination may result in
 a material dilution of the purchasers' equity interests. See Item
1602(a)(3) of
 Regulation S-K.
Summary, page 1

5. Please file as exhibits any agreements or contracts related to the
support M3 Partners
 and Brigade have agreed to provide to you in your pursuit of an initial
business
 combination, as you discuss on pages 3-4 and 110-111. See Item
601(b)(10) of
 Regulation S-K.
6. Please provide an analysis as to whether M3 Partners and Brigade are
affiliates of the
 sponsor or are promoters, each within the meaning of Securities Act Rule
405. If so,
 please provide related conflicts of interest disclosures on the cover
page and in
 the summary pursuant to Items 1602(a)(5) and (b)(7) of Regulation S-K.
7. Please expand your disclosure on pages 10 or 30, as appropriate, to
describe any
 limitations on extensions, including the number of times. See Item
1602(b)(4) of
 Regulation S-K.
8. Please revise to describe any plans to seek additional financings and
how the terms of
 additional financings may impact unaffiliated security holders. See Item
1602(b)(5) of
 Regulation S-K.
9. Please expand your disclosure outside of the table on page 13 to
describe the extent to
 which the conversion of working capital loans into warrants may result
in a material
 dilution of the purchasers' equity interests. See Item 1602(b)(6) of
Regulation S-K.
10. Please expand your disclosure on pages 42-43 to also describe conflicts
of interest
 relating to payments to your sponsor, officers or directors, or your or
their affiliates
 for services rendered prior to or in connection with the consummation of
your initial
 business combination, as referenced on page 41. See Item 1602(b)(7) of

Proceeds to be held in trust account, page 29

11. We note the disclosure in this section and elsewhere that the proceeds
in the trust
 account will not be released until "(i) the completion of our initial
business
 combination or an earlier redemption in connection with the commencement
of the
 procedures to consummate the initial business combination if we
determine it is
 desirable to facilitate the completion of the initial business
combination." We also
 note that Nasdaq Rule IM-5101-2(a) states that "[a]t least 90% of the
gross proceeds
 from the initial public offering . . . must be deposited in a trust
account maintained by
 an independent trustee . . . ." It is unclear how the release of funds
earlier than the
 consummation of the initial business combination would comport with this
listing
 standard. Please revise for consistency with the Nasdaq Listing Rules.

third party.
 However, we also note your tabular disclosure on pages 152-153, which
indicates that
 certain of your officers and directors currently serve on the board of
the Fifth SPAC.
