Explanation of Responses:

1. The securities disclosed in this Form 4 are owned by certain funds (the "Funds") managed by Monroe Capital LLC and/or its affiliates ("Monroe"). Theodore L. Koenig is the Chief Executive Officer of Monroe. By reason of the provisions of Rules 13d-3 and 16a-1 under the Securities Exchange Act of 1934, as amended, Mr. Koenig may be deemed to be the beneficial owner of the securities beneficially owned by the Funds. The filing of this statement shall not be deemed an admission that Mr. Koenig is the beneficial owner of the securities reported herein for purposes of Section 16 of the Securities Exchange Act of 1934, as amended, or otherwise. Mr. Koenig hereby disclaims beneficial ownership of all such securities, except to the extent of any indirect pecuniary interest therein.

2. Due to an inadvertent error, in a Form 4 filing made on December 10, 2021, the Reporting Person reported 6,233,333 shares beneficially owned, rather than the correct number of 250,000 in Table I, Column 5. The result of the error in subsequent filings was to over report direct holdings by the Reporting Person by 5,983,333 shares. This filing properly reflects the correct number of shares as of December 10, 2021. As of December 28, 2021, the reporting person beneficially owned 1,704,441 shares.
