Units.

 

Each
Unit (“Unit”) consists of one (1) ordinary share, par value US$0.0001 (“Ordinary Share”), of
Lakeshore Acquisition II Corp., a Cayman Islands exempted company with limited liability (the “Company”), one-half
of one redeemable warrant of the Company (“Warrant”), and one right (“Right”). Each whole Warrant
entitles the holder to purchase one Ordinary Share for US$11.50 per share (subject to adjustment). Each Warrant will become exercisable
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 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. Each right entitles the holder to receive one-tenth (1/10) of one ordinary share upon consummation of the Company’s
initial Business Combination and will expire if the Company is unable to consummate its initial Business Combination within 15
months. The Ordinary Shares, Warrant(s) and Right(s) comprising the Unit(s) represented by this certificate are not transferable
separately until fifty-two (52) days following the IPO, unless Network 1 Financial Securities, Inc. informs the Company of its decision
to allow earlier separate trading, except that in no event will the Ordinary Shares, Warrants and Rights 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 and Rights are governed by a Warrant
Agreement and a Rights Agreement, dated as of ___________, 2022 and ___________, 2022, respectively, between the Company and Continental
Stock Transfer & Trust Company, as Warrant and Rights 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 and Rights Agreement

to any Warrant holder on written request and without cost.
