As soon as practicable (and in any event within two Business Days) after the Effective Date, Odyssey shall instruct its transfer agent to issue the Settlement Shares to Monaco or its designee in accordance with the reasonable delivery instructions provided by Monaco to Odyssey on or prior to the Effective Date (the “Offering”). If Monaco does not provide delivery instructions to Odyssey on a timely basis, Odyssey shall instruct its transfer agent to deliver a physical stock certificate issued in Monaco’s name and representing all the Settlement Shares to the address for Monaco set forth in Section 9.02.

Section 3.04. Delivery of Settlement Cash. Odyssey shall deliver the Settlement Cash to Monaco or its designee as follows:

trust account, from the portion of the settlement proceeds due to Monaco and Odyssey, an amount equal to $2.5 million dollars, for the benefit of Monaco. Any Instruction delivered will be irrevocable absent Monaco’s written approval. If Beatrix Counsel receives both proceeds under the Beatrix Agreement and an Instruction on or before December 1, 2021, Odyssey shall be deemed not to be in breach of Section 3.04 if Beatrix Counsel delivers the $2.5 million to Monaco on or before December 8, 2021. Monaco shall not take, or fail to take, any action that would reasonably be expected to delay the proper disbursement of the $2.5 million by Beatrix Counsel.

Article 5

Section 5.01. Option to Convert. Monaco shall have the right at any time and from time to time during the period commencing on the Effective Date and ending the date on which Odyssey delivers $2.5 million in cash to Monaco in accordance with Section 3.04(b) (the “Conversion Period”), in accordance with the procedures set forth below, to convert all of the Secured Obligation into shares of Common Stock.

Section 5.02. Exercise of Option. If Monaco elects to exercise its right to convert the Secured Obligation, Monaco shall specify in a written notice to Odyssey (an “Exercise Notice”) (a) that Monaco elects to exercise its right to convert all of the Secured Obligation, and (b) whether the shares of Common Stock issued pursuant to this Article 5 are to be issued in the name of Monaco or a designee. As soon as practicable thereafter, Monaco shall receive one or more certificates, registered in the name of Monaco or its designee(s), representing the shares of Common Stock issued pursuant to this Article 5.

4

Section 5.03. Conversion Price. If Monaco elects to exercise its right to convert all or a portion of the Secured Obligation, then the number of shares of Common Stock that Monaco shall be entitled to receive (the “Conversion Shares”) shall equal the quotient determined by dividing (a) $2.5 million, by (b) the Conversion Price.

Section 5.04. Conversion Date. Any conversion of the Secured Obligation pursuant to this Article 5 shall be deemed to occur on the date which Monaco delivers the Exercise Notice to Odyssey (the “Conversion Date”), except that, if Monaco delivers an Exercise Notice on or after November 21, 2021, then the Conversion Date shall be December 1, 2021.
