These acquisitions or dispositions may occur in open market transactions, privately negotiated transactions or through other methods.

Additionally, the F2 Funds may distribute shares of Common Stock that they directly hold to their respective limited partners, members and/or shareholders, as applicable.

In connection with the foregoing, and as may be appropriate from time to time, each of the Reporting Persons may consider the feasibility and advisability of various alternative courses of action with respect to the Reporting Persons’ investment in the Issuer, including, without limitation: (a) the acquisition or disposition of Common Stock, including through derivative transactions which may include security-based swaps and short sales; (b) an extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Issuer or any of its subsidiaries; (c) a sale or transfer of a material amount of assets of the Issuer or any of its subsidiaries; (d) changes in the present board of directors or management of the Issuer; (e) a material change in the present capitalization or dividend policy of the Issuer; (f) other material changes in the Issuer’s business or corporate structure; (g) changes in the Issuer’s articles of incorporation or bylaws or other actions that may impede the acquisition of control of the Issuer by any person; (h) causing any class of the Issuer’s securities to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association; (i) causing a class of equity securities of the Issuer to become eligible for termination of registration pursuant to Section 12 of the Exchange Act; or (j) any action similar to those enumerated above. Except as described in Item 6 and this Item 4 and any plans or proposals that may from time to time be discussed or considered by the directors of the Issuer, including Morana Jovan-Embiricos, who is the founding director and shareholder of each of Globeways I and Globeways II and who is a member of the Issuer’s board of directors, in her fiduciary capacity as a director of the Issuer, the Reporting Persons do not currently have any plans or proposals that relate to or would result in any of the actions specified in clause (a) through (j) of this paragraph.

The Reporting Persons intend to review their investment in the Issuer from time to time on the basis of various factors, including the Issuer’s business, financial condition, results of operations and prospects, general economic and industry conditions, the securities markets in general and those for the Issuer’s stock in particular, as well as other developments.

The information set forth in Items 3 and 6 hereof is incorporated by reference in its entirety into this Item 4.

Amended and Restated Investors’ Rights Agreement

In May 2019, the Reporting Persons and certain other stockholders of the Issuer entered into an amended and restated investors’ rights agreement with the Issuer (the “Investor Rights Agreement”). Pursuant to the Investor Rights Agreement and subject to the terms and conditions therein, the parties agreed that:

Registration Rights

Following the closing of the IPO, the holders of a certain number of shares of Common Stock, or their transferees, became entitled to the registration rights set forth below with respect to registration of the resale of such shares under the Securities Act pursuant to the Investors Rights Agreement.

Demand Registration Rights

Beginning 180 days after the effective date of the registration statement for the IPO, upon the written request from the holders of a majority of the outstanding registrable securities (as defined in the Investor Rights Agreement), the Issuer will be required to file a registration statement and use commercially reasonable efforts to effect the registration of all or a portion of their registrable securities for public resale so long as the total amount of registrable shares requested to be registered has an anticipated aggregate offering price to the public, net of selling expenses, of least $50.0 million. The Issuer is required to effect only one registration pursuant to this provision of the Investor Rights Agreement.

Short-Form Registration Rights

Pursuant to the Investor Rights Agreement, if the Issuer is eligible to file a registration statement on Form S-3, upon the written request of the holders of a majority of Issuer’s outstanding registrable securities, the Issuer will be required to file a Form S-3 registration statement with respect to their registrable securities so long as the total amount of registrable securities requested to be registered has an anticipated aggregate offering price to the public, net of selling expenses, of least $25.0 million. The Issuer is required to effect only one registration in any twelve-month period pursuant to this provision of the Investor Rights Agreement. The right to have such shares registered on Form S-3 is further subject to other specified conditions and limitations.

Piggyback Registration Rights

Pursuant to the Investor Rights Agreement, if the Issuer registers any securities either for its own account or for the account of other security holders, the holders of registrable securities are entitled to include their shares in the registration. Subject to certain exceptions contained in the Investor Rights Agreement, the Issuer and the underwriters may limit the number of shares included in the underwritten offering to the number of shares which the Issuer and the underwriters determine in its sole discretion will not jeopardize the success of the offering.

Indemnification

The Investor Rights Agreement contains customary cross-indemnification provisions, under which the Issuer is obligated to indemnify holders of registrable securities in the event of material misstatements or omissions in the registration statement attributable to it, and the holders of registrable securities are obligated to indemnify the Issuer for material misstatements or omissions attributable to them.

Expiration of Registration Rights

The demand registration rights, short-form registration rights and piggyback registration rights granted under the Investor Rights Agreement will terminate on the fifth anniversary of the IPO.
