  Units. 
 Each Unit (“Unit”) consists of one (1) share of common stock, par value $0.0001 per share (“Common
Stock”), of Legato Merger Corp., a Delaware corporation (the “Company”), and one warrant of the Company (“Warrant”). Each Warrant entitles the holder to purchase one share of Common Stock for $11.50 per
share (subject to adjustment). Each Warrant will become exercisable on the later of (i) 30 days after the Company’s completion of an initial merger, capital stock exchange, asset acquisition, or other similar business combination with one or
more businesses or entities (a “Business Combination”) and (ii) 12 months from the closing of the Company’s initial public offering (“IPO”), and will expire unless exercised before 5:00 p.m., New York City
Time, on the fifth anniversary of the completion of an initial Business Combination, or earlier upon redemption or liquidation. The Common Stock and Warrant(s) comprising the Unit(s) represented by this certificate are not transferable separately
until ninety (90) days following the IPO, unless EarlyBirdCapital, Inc. informs the Company of its decision to allow earlier separate trading, except that in no event will the Common Stock and Warrants be separately tradeable until the Company
has filed an audited balance sheet reflecting the Company’s receipt of the gross proceeds of its initial public offering and issued a press release announcing when such separate trading will begin. The terms of the Warrants are governed by a
Warrant Agreement, dated as of            , 2020, between the Company and Continental Stock Transfer & Trust Company, as Warrant Agent, and are subject to the terms and provisions
contained therein, all of which terms and provisions the holder of this certificate consents to by acceptance hereof. Copies of the Warrant Agreement are on file at the office of the Warrant Agent at 1 State Street, 30th Floor, New York, New York 10004, and are available to any Warrant holder on written request and without cost. 

This certificate is not valid unless countersigned by the Transfer Agent and Registrar of the Company. Witness the facsimile seal of the Company and the
facsimile signatures of its duly authorized officers.
