The Issuer, RiverVest II, RiverVest II (Ohio), RiverVest III, RiverVest III (Ohio), 3x5 RiverVest II, 3x5 RiverVest II-B and certain other investors are party to an amended and restated investor rights agreement, as amended (the “Investor Rights Agreement”), dated November 30, 2017, giving such parties the right to demand that the Issuer file a registration statement or request that the investors’ shares of Common Stock be covered by a registration statement that the Issuer otherwise files. The registration rights terminate upon the earliest of (i) the date that is three years after the closing of the IPO and (ii) as to a given holder of registration rights, the date after the closing of the IPO when such holder of registration rights can sell all of such holder’s registrable securities during any ninety day period pursuant to Rule 144 of the Securities Act of 1933, as amended.

This foregoing description of the Investor Rights Agreement is qualified in its entirety by reference to the Investor Rights Agreement, a copy of which is filed as Exhibit B hereto and is incorporated herein by reference.

The Issuer, along with its directors, executive officers and substantially all of its other stockholders, including RiverVest II, RiverVest II (Ohio), RiverVest III, RiverVest III (Ohio), 3x5 RiverVest II, and 3x5 RiverVest II-B, have agreed with the underwriters for the IPO that, for a period of 180 days following July 18, 2018, they will not offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise dispose of any shares of the Common Stock (including any shares issued in the IPO), or any options or warrants to purchase any shares of Common Stock, or any securities convertible into, exchangeable for or that represent the right to receive shares of Common Stock, whether now owned or later acquired, owned directly or with respect to which they have beneficial ownership within the rules and regulations of the SEC, subject to specified exceptions. The representatives of the underwriters, on behalf of the underwriters, may, in their sole discretion, at any time without prior notice, release all or any portion of the shares from the restrictions in any such agreement.
