Pursuant to the TSA, the Company agreed to a delayed draw new money financing in which the Company (i) may cause to be issued to the Purchasers (including OCS) an aggregate principal amount of $25.0 million in the form of a new stapled security, comprised of (A) second lien PIK convertible notes (the “Notes”) and (B) shares of Series B Preferred Stock (as defined below), (ii) facilitated the exchange of $100.0 million of the aggregate principal amount of the term loans under the 2022 Credit Agreement held by certain of the Preferred Equityholders (including OCS) for Notes and Series B Preferred Stock as described below and (iii) agreed to certain other changes to the terms of the 2022 Credit Agreement, including modifications of the financial covenants thereunder.

The Notes are convertible into Shares at a fixed conversion price of $12.50 (as adjusted for the Reverse Stock Split and subject to adjustment as provided in the Note Purchase Agreement (as defined below)).

On June 15, 2023 (the “Closing Date”), the Company completed the Transaction, which was approved by the Company’s stockholders at the Company’s annual meeting of stockholders held on June 13, 2023. On the Closing Date, certain previously executed agreements became effective, including (i) Amendment No. 2 to the 2022 Credit Agreement (the “Credit Agreement Amendment”), by, among others, Opco, Holdings, Barclays Bank PLC, as administrative agent and issuing bank (the “Administrative Agent”), and the lenders party thereto (including certain of the Reporting Persons), which amends the 2022 Credit Agreement, (ii) a Second Lien Note Purchase Agreement (the “Original Note Purchase Agreement”), by, among others, the Company, Wilco Holdco, Inc. (“Wilco”), Holdings, Opco, the purchasers from time to time party thereto (including OCS, the “Purchasers”) and Wilmington Savings Fund Society, FSB, as purchaser representative (the “Purchaser Representative”) and (iii) certain other definitive agreements relating to the Transaction (such documents referred to collectively as the “Signing Date Definitive Documents”).

In addition, on the Closing Date, the Company entered into or filed with the Secretary of State of the State of Delaware, as applicable, certain other agreements (collectively, the “Closing Date Definitive Documents”) to implement certain terms of the TSA. The Closing Date Definitive Documents include (i) the First Amendment to Note Purchase Agreement (together with the Original Note Purchase Agreement, the “Note Purchase Agreement”), dated as of the Closing Date, by and among the Company, Wilco, Holdings, Opco, the Purchasers party thereto (in such capacity, the “First Amendment Purchasers”, which includes OCS)) and the Purchaser Representative, pursuant to which the First Amendment Purchasers agreed to purchase, and the Company agreed to issue, an additional $3,243,302.02 aggregate principal amount of Notes (including $286,719.49 to OCS), (ii) the Consent to Amendment No. 2 to Credit Agreement, dated as of the Closing Date, by, among others, Opco, Holdings, the lenders party thereto and the Administrative Agent, which amends the Credit Agreement Amendment, (iii) the First Amended and Restated Certificate of Designation of Series A Senior Preferred Stock of the Company, dated as of June 15, 2023 (the “A&R Series A COD”), which, as agreed under the TSA, (A) revised the Preferred Equityholders’ preexisting rights to designate and elect one director to the Board to provide that the Preferred Equityholders have the right to appoint three additional directors to the Board (resulting in the right of the Preferred Equityholders to appoint a total of four directors to the Board) until such time after the Closing Date that the Lead Purchaser (in each case, as defined in certain of the transaction agreements entered into in connection with the original issuance of the Series A Senior Preferred Stock) ceases to hold at least 50.1% of the Series A Preferred Senior Stock held by it as of the Closing Date, and (B) removed the provision that eliminated the Preferred Equityholders’ director designation rights upon the Company’s achievement of certain amounts of EBITDA; (iv) the First Amendment to that certain Investors’ Rights Agreement (as amended, the “Investors’ Rights Agreement”), dated as of February 24, 2022, by and among the Company and the Preferred Equityholders listed therein, which made changes similar to those under the A&R Series A COD and further provided that (A) all designee directors of the Preferred Equityholders will be subject to consideration by the Board (acting in good faith and consistent with their review of other Board candidates) and (B) at least one director appointed in accordance with the A&R Series A COD be unaffiliated with (and independent of) the Preferred Equityholders and meet the definition of “independent” under the listing standards of the New York Stock Exchange, and by the Securities and Exchange Commission; (v) the Certificate of Designation of Series B Preferred Stock of the Company, dated as of June 15, 2023 (the “Series B COD”), which Series B Preferred Stock is further described below, (vi) the Registration Rights Agreement, dated as of June 15, 2023, by and among the Company and the Purchasers with respect to the resale of shares of Common Stock into which the Notes are convertible; and (vii) such other related documents and ancillary agreements required to implement the Transaction.

Issuance of New Second Lien PIK Convertible Notes and Series B Preferred Stock

On the Closing Date, pursuant to the Note Purchase Agreement and the other Signing Date Definitive Documents, the Company (i) exchanged $100.0 million of the aggregate principal amount of the term loans under the 2022 Credit Agreement held by certain of the Preferred Equityholders for $100.0 million aggregate principal amount of a new stapled security, comprised of (A) Notes and (B) shares of Series B Preferred Stock, par value $0.0001 per share (the “Series B Preferred Stock”), which provide the holder thereof with voting rights such that the holders thereof have the right to vote on corporate matters on an as-converted basis as if the conversion occurred at an initial price per share equal to $12.87, and (ii) issued to the First Amendment Purchasers, and the First Amendment Purchasers purchased from the Company, an aggregate principal amount of $3,243,302.02 million in Notes and shares of stapled Series B Preferred Stock.
