Lock-up Agreement

Pursuant to lock-up agreements (each, a “Lock-Up Agreement”) signed in connection with the Issuer’s initial public offering, Pivotal, certain other stockholders of the Issuer and each director and officer of the Issuer agreed with the representatives of the underwriters in the initial public offering (the “Representatives”), subject to certain exceptions, not to offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to sale of or otherwise dispose of or transfer any shares of Common Stock or any securities convertible into or exercisable or exchangeable for shares of Common Stock, request or demand that the Issuer file a registration statement related to the Common Stock, or enter into any swap or other agreement that transfers to another, in whole or in part, directly or indirectly, the economic consequence of ownership of the Common Stock, for a period ending on the date that is 180 days after the date of the prospectus in connection with the Issuer’s initial public offering, except with the prior written consent of the Representatives.

 

15


Investor Rights Agreement

On June 26, 2020, the Issuer, Pivotal and certain other parties entered into investors’ rights agreement (the “Investor Rights Agreement”). Beginning 180 days after the effectiveness of the Issuer’s registration statement filed in connection with its initial public offering, the Investor Rights Agreement provides Pivotal and other parties thereto with certain demand registration rights, including shelf registration rights, in respect of the shares of Common Stock issued to it upon conversion of the Preferred Shares or upon exercise of the Warrants, subject to certain conditions. The stockholders may only require two registration statements on Form S-3 in a 12-month period. In addition, in the event that the Issuer registers additional shares of Common Stock for sale to the public, it will be required to give notice of such registration to Pivotal and certain other parties of its intention to effect such a registration, and, subject to certain limitations, include the shares of Common Stock held by them in such registration. The registration rights will expire, with respect to any particular holder, five years following the Issuer’s initial public offering. The Investor Rights Agreement contains customary cross-indemnification provisions, pursuant to which the Issuer is obligated to indemnify Pivotal and other parties in the event of material misstatements or omissions in the registration statement attributable to the Issuer or any violation or alleged violation whether by action or inaction by the Issuer under certain securities laws and Pivotal is obligated to indemnify the Issuer for material misstatements or omissions in the registration statement attributable to it.

The descriptions of the Lock-Up Agreement and the Investor Rights Agreement contained in this Item 6 are qualified in their entirety by reference to the full text of the agreements, which are attached hereto as Exhibit 2 and Exhibit 3, and incorporated by reference herein.
