Pursuant to the Letter Agreement, A.T.

Holdings II or any equity holders of any subsidiary of A.T. Holdings II other than A.T. Holdings II or any affiliates of A.T.

Further, the foregoing restrictions also do not apply to pledges to Oaktree (as defined below) pursuant to debt agreements and any transfers to Oaktree upon foreclosure, and transfers in connection with a change-of-control transaction. In addition, A.T. Holdings II has agreed that, if during the restricted period, the Issuer launches and closes an underwritten equity primary financing resulting in at least $50 million net proceeds (after underwriting discount and commission), it will enter into a customary 90-day lockup agreement with the underwriters of such offering.

Settlement Term Sheet for Credit and Security Agreement

As previously disclosed, A.T. Holdings II is a borrower under the Credit and Security Agreement. On February 2, 2023, A.T. Holdings II entered into a binding term sheet with Oaktree Fund Administration, LLC, as Agent under the Credit and Security Agreement (the “Agent”), and Oaktree Capital Management, L.P., on behalf of the lenders party to the Credit and Security Agreement (collectively, “Oaktree”), which sets forth the principal terms of a settlement with respect to the indebtedness under the Credit and Security Agreement (the “Settlement Term Sheet”). Pursuant to the Settlement Term Sheet, the net cash proceeds from the Registered Sale will be used to repay a portion of A.T. Holdings II’s obligations under the Credit and Security Agreement. Pursuant to the Settlement Term Sheet, Oaktree and A.T. Holdings II agreed to enter into an amended and restated Credit and Security Agreement (the “Amended Credit and Security Agreement”) within 15 days following the closing of the Registered Sale that will have a maturity date of April 15, 2024.

As partial consideration for Oaktree’s agreement to enter into the Amended Credit and Security Agreement and its other undertakings pursuant to the Settlement Term Sheet, Oaktree will receive a consent fee, including certain share distributions (the “Oaktree Share Distributions”) set forth in a distribution agreement to be entered into by A.T. Holdings II and Oaktree. Pursuant to the Settlement Term Sheet, if the obligations under the Credit and Security Agreement are not repaid in full within 14 days following the closing of the Registered Sale, then following repayment in full of all obligations under the Amended Credit and Security Agreement, 25% of the Common Shares held by A.T. Holdings II after giving effect to the Registered Sale and the ADCPS Share Distribution (as defined below) but before giving effect to any additional sales of Common Shares by A.T. Holdings II (such amount, the “Remaining ADCT Shares”) shall be transferred to Oaktree. If the obligations under the Credit and Security Agreement are repaid in full within 14 days following the closing of the Registered Sale, then following repayment in full of all obligations under the Amended Credit and Security Agreement, 15% of the Remaining ADCT Shares shall be transferred to Oaktree. Pursuant to the Settlement Term Sheet, the Forbearance Period for the Credit and Security Agreement was extended to February 6, 2023, and if the Registered Sale is consummated on or before February 6, 2023, and the net proceeds from the Registered Sale are applied in accordance with the Settlement Term Sheet and no other breach of the Settlement Term Sheet or the financing documents in connection with the Credit and Security Agreement has occurred, the Forbearance Period will be extended to February 21, 2023.

In addition, following the consummation of the Registered Sale, 100% of the net cash proceeds from any future sales of Common Shares by A.T. Holdings II that Oaktree will permit in its sole discretion shall be used to repay A.T. Holdings II’s obligations under the Amended Credit and Security Agreement. Further, A.T. Holdings II will use best efforts to cause ADC Products to effectively distribute all Common Shares held by it to its shareholders, including A.T. Holdings II, on a pro rata basis within a reasonable timeframe (the “ADCPS Share Distribution”), and any such Common Shares distributed to A.T. Holdings II will remain subject to a perfected first priority security interest in favor of Agent.

The Settlement Term Sheet further provides that following the Registered Sale, Oaktree (solely with respect to the Oaktree Share Distribution and Common Shares received in the event Oaktree enforces its rights under the Amended Credit and Security Agreement or any related financing documents) and A.T. Holdings II will each enter into a lock-up agreement, pursuant to which they will agree not to sell Common Shares held by them into the public market until the later of (i) 365 days after the date of the final prospectus relating to the Registered Sale and (ii) 90 days following a bona fide underwritten equity primary financing of at least $50 million net proceeds launched and closed by the Issuer on or before 365 days after the date of the final prospectus relating to the Registered Sale; provided that Oaktree and A.T. Holdings II shall not be prevented from selling such Common Shares with the permission of the Issuer. Further, pursuant to the Settlement Term Sheet, the Issuer will enter into a registration rights agreement with Oaktree, which shall provide for registration rights with respect to the Common Shares held as collateral for the obligations under the Amended Credit and Security Agreement in the event Oaktree enforces its rights under the Amended Credit and Security Agreement or any related financing documents against any such Common Shares.
