Seaport Global Acquisition II Corp., a Delaware corporation (“Maker”),
promises to pay to the order of Seaport Global SPAC II, LLC, a Delaware limited liability company, or its registered assigns or successors
in interest (collectively, “Payee”), or order, the principal sum of Four Hundred Thousand Dollars ($400,000) or such
lesser amount as shall have been advanced by Payee to Maker and shall remain unpaid under this Note on the Maturity Date (as defined below)
in lawful money of the United States of America, on the terms and conditions described below. All payments on this Note shall be made
by check or wire transfer of immediately available funds or as otherwise determined by Maker to such account as Payee may from time to
time designate by written notice in accordance with the provisions of this Note.


 


1.            Principal.
The entire unpaid principal balance of this Note shall be due and payable on the earlier of: (i) June 21, 2022, and (ii) the
date on which Maker consummates an initial public offering of its securities (such earlier date of (i) and (ii), the “Maturity
Date”) unless accelerated upon the occurrence of an Event of Default (as defined below). The principal balance may be prepaid
at any time by Maker, at its election and without penalty. Under no circumstances shall any individual, including but not limited to any
officer, director, employee or shareholder of Maker, be obligated personally for any obligations or liabilities of Maker hereunder.


 


2.            Drawdown
Requests. Maker and Payee agree that Maker may request, from time to time, up to Four Hundred Thousand Dollars ($400,000) in drawdowns
under this Note to be used for costs and expenses related to Maker’s proposed initial public offering of its securities (the “IPO”),
including its formation. The principal of this Note may be drawn down from time to time prior to the Maturity Date upon request from Maker
to Payee (each, a “Drawdown Request”). Each Drawdown Request must state the amount to be drawn down, and must not be
an amount less than Ten Thousand Dollars ($10,000) unless agreed upon by Maker and Payee. Payee shall fund each Drawdown Request no later
than three (3) business days after receipt of a Drawdown Request; provided, however, that the maximum amount of drawdowns
outstanding under this Note at any time may not exceed Four Hundred Thousand Dollars ($400,000). No fees, payments or other amounts shall
be due to Payee in connection with, or as a result of, any Drawdown Request by Maker.


 


3.            Interest.
No interest shall accrue on the unpaid principal balance of this Note.


 


4.            Application
of Payments. All payments shall be applied first to payment in full of any costs incurred in the collection of any sum due under this
Note, including (without limitation) reasonable attorney’s fees, then to the payment in full of any late charges and finally to
the reduction of the unpaid principal balance of this Note.
