The Cooperation Agreement provides that it will terminate on the date that is the earlier of (i) one hundred fifty (150) days prior to the 2022 annual meeting of stockholders of the Issuer (the “2022 Annual Meeting”) and (ii) one hundred fifty (150) days prior to the first anniversary of the 2021 Annual Meeting, except that if the Issuer notifies the Reporting Persons that the Board has determined to nominate Mr. Robotti for election at the 2022 Annual Meeting by no later than the earlier of (i) one hundred sixty-five (165) days prior to the 2022 Annual Meeting and (ii) one hundred sixty-five (165) days prior to the first anniversary of the 2021 Annual Meeting, the term of the Cooperation Agreement will be extended until the date that is the earlier of (i) one hundred fifty (150) days prior to the 2023 annual meeting of stockholders of the Issuer and (ii) one hundred fifty (150) days prior to the first anniversary of the 2022 Annual Meeting.
