ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER

Investors’ Rights Agreement

Atlas X and certain other stockholders of the Issuer entered into a Second Amended and Restated Investors’ Rights Agreement dated April 2, 2018 (the “Investors’ Rights Agreement”), with the Issuer. Under the Investors’ Rights Agreement, holders of registrable securities are entitled to rights with respect to the registration of these securities under the Securities Act of 1933, as amended (the “Securities Act”). The Investors’ Rights Agreement includes demand registration rights, short-form registration rights and piggyback registration rights. All fees, costs and expenses incurred in connection with registrations under the Investors’ Rights Agreement will be borne by the Issuer, and all selling expenses, including underwriting discounts and selling commissions, will be borne by the holders of the shares being registered.

 

   

 

CUSIP 55910K108 Page 11 of 14

 

Demand Registration Rights

The holders of registrable securities are entitled to demand registration rights. The Issuer will be required, upon the request of holders of at least 25% of outstanding registrable securities, to file a registration statement with an anticipated offering amount of at least $3.0 million and use commercially reasonable efforts to effect the registration of these shares for public resale. The Issuer is required to effect up to two registrations pursuant to this provision of the Investors’ Rights Agreement.

Short Form Registration Rights

The holders of registrable securities are also entitled to short form registration rights. Pursuant to the Investors’ Rights Agreement, if the Issuer is eligible to file a registration statement on Form S-3, upon the request of holders of at least 10% of outstanding registrable securities to sell registrable securities with an anticipated aggregate offering amount of at least $1.0 million, the Issuer will be required to use commercially reasonable efforts to effect a registration of such shares. The Issuer is required to effect up to two registrations in any twelve month period pursuant to this provision of the Investors’ Rights Agreement.

Piggyback Registration Rights

The holders of registrable securities are entitled to piggyback registration rights. If the Issuer registers any of its securities either for its own account or for the account of other security holders, the holders of outstanding registrable securities are entitled to include their shares in the registration. Subject to certain exceptions contained in the Investors’ Rights Agreement, the Issuer and the underwriters may limit the number of shares included in the underwritten offering if the underwriters determine that marketing factors require a limitation of the number of shares to be underwritten.

Indemnification

The Investors’ 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 the Issuer, and they are obligated to indemnify the Issuer for material misstatements or omissions attributable to them.

 

Expiration of Registration Rights

The registration rights granted under the Investors’ Rights Agreement will terminate upon the earlier of (i) a deemed liquidation event, as defined in the Issuer’s amended and restated certificate of incorporation (as in effect prior to the completion of its initial public offering) or certain other events constituting a sale of the Issuer, (ii) at such time after the Issuer’s initial public offering when all registrable securities could be sold under Rule 144 of the Securities Act or a similar exemption without limitation during a three-month period without registration or (iii) the fifth anniversary of the Issuer’s initial public offering.
