| 1. The shares represent restricted stock units received by Daniel Sundheim ("Mr. Sundheim"), which vest in full on the earlier of (i) the date of the Issuer's next annual meeting of stockholders (or the date immediately prior to such meeting if Mr. Sundheim's service as a director ends at such meeting due to Mr. Sundheim's failure to be re-elected or Mr. Sundheim not standing for re-election) or (ii) the one-year anniversary of the grant date, in each case subject to Mr. Sundheim's continued service through such date. |
| 2. Represents securities held by Mr. Sundheim. Mr. Sundheim may be deemed to hold the securities reported herein for the benefit of certain funds and accounts to which the Investment Manager (as defined below) serves as the investment manager or investment consultant. |
| 3. This statement is filed by D1 Capital Partners L.P. (the "Investment Manager") and Mr. Sundheim. The foregoing persons are hereinafter sometimes referred to as the "Reporting Persons." The filing of this statement should not be construed as an admission that any Reporting Person is, for the purposes of Section 16 of the Securities Exchange Act of 1934, as amended, the beneficial owner of the securities reported except to the extent of its pecuniary interest therein, if any. |
| 4. The securities reported herein are held by D1 Master Holdco I LLC ("D1 Master Holdco"), certain related entities, GCM Grosvenor IC SPV, LLC ("GCM IC") and GCM Grosvenor IC SPV 2, LLC ("GCM IC 2").
