(f) Citizenship:

Prior to the initial public offering of Hudson Executive Investment Corp., a Delaware corporation (“HEC”) and the predecessor in interest to the Issuer, HEC Sponsor LLC, a Delaware limited liability company (the “Sponsor”) purchased 8,625,000 Class B ordinary shares of HEC for an aggregate purchase price of $25,000, or approximately $0.002 per share (the “Founder Shares”). On May 20, 2020, the Sponsor transferred 25,000 Founder Shares to Amy Schulman, a director, and on June 3, 2020 the Sponsor transferred 25,000 shares to Thelma Duggin, a director, resulting in the Sponsor holding an aggregate of 8,575,000 Founder Shares. In connection with HEC’s initial public offering, the Sponsor purchased warrants to purchase 10,280,000 Class A ordinary shares of HEC for an aggregate purchase price $10.28 million, or $1.00 per warrant (the “Private Placement Warrants”). On June 8, 2020, HEC effected a 1.2:1 stock split resulting in an increase in the total number of Founder Shares outstanding from 8,625,000 to 10,350,000 in order to maintain the ownership of Founder Shares by the Sponsor at 20% of the issued and outstanding ordinary shares of HEC upon consummation of its initial public offering. The Sponsor purchased the Founder Shares and Private Placement Warrants with its working capital.

In addition, HEC entered into a forward purchase agreement (the “FPA”) with HEC Master pursuant to which HEC Master committed to purchase from HEC up to 5,000,000 forward purchase units (the “Forward Purchase Units”), consisting of one share of Class A common stock (the “Forward Purchase Shares”) and one-half of one warrant to purchase one share of Class A common stock (the “Forward Purchase Warrants” and together with the Forward Purchase Units and the Forward Purchase Shares, the “Forward Purchase Securities”), for $10.00 per unit, or an aggregate amount of up to $50,000,000, in a private placement that closed concurrently with the closing of a Business Combination. The Reporting Persons used working capital to purchase the Forward Purchase Securities pursuant to the Forward Purchase Agreement.

On June 22, 2021, in connection with the closing of the Business Combination, each Founder Share automatically converted into one share of Common Stock of the Issuer for no additional consideration.

Following the conversion of the Founder Shares as a result of the closing of the Business Combination, the Sponsor distributed its shares of Common Stock to the Reporting Persons. The Reporting Persons collectively received 7,424,446 shares of Common Stock and 7,410,000 warrant to purchase Common Stock from the distribution from the Sponsor.

Business Combination

On January 12, 2021, HEC entered into Agreement and Plan of Merger, dated as of January 12, 2021 (the “Merger Agreement”), by and among HEC (which after the business combination became Talkspace), Groop Internet Platform, Inc. (“Old Talkspace”), Tailwind Merger Sub I, Inc., a Delaware corporation and a direct wholly owned subsidiary of HEC (“First Merger Sub”), and Tailwind Merger Sub II, LLC, a Delaware limited liability company (“Second Merger Sub”). Pursuant to the Merger Agreement, the parties thereto entered into a business combination transaction (the “Business Combination”) by which, (i) First Merger Sub merged with and into HEC with HEC being the surviving corporation in the merger (the “First Merger”) and (ii) Second Merger Sub merged with and into the surviving corporation with Second Merger Sub being the surviving entity in the merger (the “Second Merger” and, together with the First Merger, being collectively referred to as the “Mergers” and, together with the other transactions contemplated by the Merger Agreement, the “Transactions” and the closing of the Transactions, the “Closing”).

Forward Purchase Agreement

In addition, HEC entered into the FPA with HEC Master pursuant to which HEC Master committed to purchase from the Company up to 5,000,000 Forward Purchase Units, consisting of one Forward Purchase Share and one-half of one Forward Purchase Warrants, for $10.00 per unit, or an aggregate amount of up to $50,000,000, in a private placement that will close concurrently with the closing of a Business Combination. In connection with the signing of the Merger Agreement, HEC and HEC Master amended the FPA. Pursuant to the First Amendment to the Forward Purchase Agreement, dated January 12, 2021, HEC Master’s purchase obligations were amended such that HEC Master is obligated to purchase 2,500,000 Forward Purchase Units and backstop up to $25,000,000 of redemptions by HEC stockholders through the purchase of additional Forward Purchase Units, in each case valued at $10.00 per Forward Purchase Unit, in a private placement that closed concurrently with the closing of the Business Combination.

Registration Rights Agreement

Pursuant to a registration rights agreement entered into on June 8, 2020, the holders of the Founder Shares and Forward Purchase Securities (and any Class A common stock issuable upon the exercise of the Founder Shares or Forward Purchase Warrants are entitled to registration rights, requiring HEC to register such securities for resale (in the case of the Founder Shares, only after conversion to shares of Class A common stock). The holders of these securities are entitled to make up to three demands, excluding short form registration demands, that HEC register such securities. In addition, the holders will have certain “piggyback” registration rights with respect to registration statements filed subsequent to the completion of a Business Combination. HEC will bear the expenses incurred in connection with the filing of any such registration statements.

At the closing of the Business Combination, HEC, the Sponsor, Old Talkspace’s independent directors, certain former stockholders of Old Talkspace and certain other parties thereto entered into an Amended and Restated Registration Rights Agreement, pursuant to which pursuant to which the Issuer agreed to register for resale, pursuant to Rule 415 under the Securities Act, certain shares of Common Stock and other equity securities that are held by the parties thereto from time to time.
