(a)-(b)

Beneficial Ownership Subject to the Conversion Cap

As of the date of this Amendment No. 10, the Reporting Persons beneficially own 10,968,840 shares of Common Stock, constituting approximately 19.90% of the outstanding shares of Common Stock, based on 44,150,959 shares of Common Stock reported to be outstanding as of May 6, 2021 in the Issuer’s quarterly report on Form 10-Q filed on May 10, 2021 (the “Reported Outstanding Share Number”). Based on the Reported Outstanding Share Number, the Conversion Cap as of the date of this Amendment No. 10 is 10,968,840 shares of Common Stock, and the Reporting Persons would not be deemed to beneficially own any shares of Common Stock in excess of such amount.

Beneficial Ownership Without Giving Effect to the Conversion Cap

Without giving effect to the Conversion Cap, based on the Reported Outstanding Share Number, as of the date of this Amendment No. 10, the Reporting Persons would beneficially own 14,939,845 shares of Common Stock, which is the number of shares of Common Stock that would be issuable upon conversion of 268,917 shares of Series A Preferred Stock held by Silver Holdings without giving effect to the Conversion Cap, constituting approximately 25.28% of the outstanding shares of Common Stock.

In addition, as of the date of this Amendment No. 10, Siris Capital Group and Siris Group GP would beneficially own (i) 32,038 shares of Common Stock received upon the vesting of restricted stock awards assigned by Messrs. Baker and Berger to Siris Capital Group pursuant to assignment agreements between Siris Capital Group, such individual and the Issuer, each dated as of February 15, 2018 (the “Assignment Agreements”) and (ii) 99,626 shares of Common Stock underlying exercisable stock options assigned by Messrs. Baker and Berger to Siris Capital Group pursuant to the Assignment Agreements, which constitute an additional approximately .30% of the outstanding shares of Common Stock. See “Restricted Stock Awards” and “Stock Option Awards” below.

Series A Preferred Stock and the Conversion Cap

Pursuant to the Certificate of Designations for the Series A Preferred Stock, dated as of February 15, 2018, filed by the Issuer with the State of Delaware (the “Certificate of Designations”), if Silver Holdings or any affiliates of Silver Holdings with which it has formed a “group” within the meaning of Rule 13d-5 under the Exchange Act (Silver Holdings, collectively with each such affiliate, the “Capped Holders”) have elected to convert some or all of their shares of Series A Preferred Stock and if the sum, without duplication, of (i) the aggregate number of shares of Common Stock issued to such holders upon such conversion and any shares of Common Stock previously issued to such holders upon conversion, plus (ii) the number of shares of Common Stock underlying shares of Series A Preferred Stock held at such time by such holders (after giving effect to such conversion), would exceed 19.90% of the issued and outstanding shares of the Issuer’s voting stock on an as converted basis (the “Conversion Cap”), then such holders would only be entitled to convert such number of shares as would result in the sum of clauses (i) and (ii) (after giving effect to such conversion) being equal to the Conversion Cap (after giving effect to any such limitation on conversion). In addition, pursuant to the Certificate of Designations, if the sum, without duplication, of (i) the aggregate voting power of the shares of Common Stock previously issued to the Capped Holders upon conversion of shares of Series A Preferred Stock at the applicable record date, plus (ii) the aggregate voting power of the shares of Series A Preferred Stock held by the Capped Holders as of such record date, would exceed 19.99% of the total voting power of the Issuer’s outstanding voting stock at such record date, then, with respect to such shares, the Capped Holders would only be entitled to cast a number of votes equal to 19.99% of such total voting power and therefore would not have the power to vote, or to direct the voting of, shares of Common Stock in excess of that amount. Based on the Reported Outstanding Share Number, the Capped Holders would be permitted to exercise their right to convert approximately 195,069 shares of the Series A Preferred Stock into shares of Common Stock.
