	Principal Amount: Up to U.S.$300,000	  	Dated as of February 17, 2021

 FOR VALUE RECEIVED and subject to the terms and conditions set forth herein, RMG Acquisition Corp. IV, a
Cayman Islands exempted company (“Maker”), promises to pay to RMG Sponsor IV, LLC, a Delaware limited liability company (“Payee”), or order, the principal sum of Three Hundred Thousand U.S. Dollars (U.S.$300,000) 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 in full on the earlier of:
(i) December 31, 2021, 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 Three Hundred Thousand U.S. Dollars (U.S.$300,000) in draw downs 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 U.S. Dollars (U.S.$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 Three Hundred Thousand U.S. Dollars (U.S.$300,000). 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. 












 5. Events of Default. The following shall constitute an event of default (“Event of
Default”): 
 (a) Failure to Make Required Payments. Failure by Maker to pay the principal amount due pursuant to this Note
on the Maturity Date. 
 (b) Voluntary Bankruptcy, Etc. The commencement by Maker of a voluntary case under any applicable bankruptcy,
insolvency, reorganization, rehabilitation or other similar law, or the consent by it to the appointment of or taking possession by a receiver, liquidator, assignee, trustee, custodian, sequestrator (or other similar official) of Maker or for any
substantial part of its property, or the making by it of any assignment for the benefit of creditors, or the failure of Maker generally to pay its debts as such debts become due, or the taking of corporate action by Maker in furtherance of any of
the foregoing. 
 (c) Involuntary Bankruptcy, Etc. The entry of a decree or order for relief by a court having jurisdiction in the
premises in respect of Maker in an involuntary case under any applicable bankruptcy, insolvency or other similar law, or appointing a receiver, liquidator, assignee, custodian, trustee, sequestrator (or similar official) of Maker or for any
substantial part of its property, or ordering the winding-up or liquidation of its affairs, and the continuance of any such decree or order unstayed and in effect for a period of sixty (60) consecutive
days. 
 6. Remedies. 
 (a) Upon the
occurrence of an Event of Default specified in Section 5(a) hereof, Payee may, by written notice to Maker, declare this Note to be due immediately and payable, whereupon the unpaid principal amount of this Note, and all other amounts payable

notwithstanding. 
 (b) Upon the occurrence of an Event of Default specified in Sections 5(b) or 5(c), the unpaid principal balance of this
Note, and all other sums payable with regard to this Note, shall automatically and immediately become due and payable, in all cases without any action on the part of Payee. 

7. Waivers. Maker and all endorsers and guarantors of, and sureties for, this Note waive presentment for payment, demand, notice of dishonor,
protest, and notice of protest with regard to the Note, all errors, defects and imperfections in any proceedings instituted by Payee under the terms of this Note, and all benefits that might accrue to Maker by virtue of any present or future laws
exempting any property, real or personal, or any part of the proceeds arising from any sale of any such property, from attachment, levy or sale under execution, or providing for any stay of execution, exemption from civil process, or extension of
time for payment; and Maker agrees that any real estate that may be levied upon pursuant to a judgment obtained by virtue hereof, on any writ of execution issued hereon, may be sold upon any such writ in whole or in part in any order desired by
Payee. 
 8. Unconditional Liability. Maker hereby waives all notices in connection with the delivery, acceptance, performance, default, or
enforcement of the payment of this Note, and agrees that its liability shall be unconditional, without regard to the liability of any other party, and shall not be affected in any manner by any indulgence, extension of time, renewal, waiver or
modification granted or consented to by Payee, and consents to any and all extensions of time, renewals, waivers or modifications that may be granted by Payee with respect to the payment or other provisions of this Note, and agrees that additional
makers, endorsers, guarantors, or sureties may become parties hereto without notice to Maker or affecting Maker’s liability hereunder.
