 Roman DBDR Tech Acquisition Corp. II, a Delaware corporation and blank check company (the
“Maker”), promises to pay to the order of Roman DBDR Tech Sponsor II LLC or its registered assigns or successors in interest (the “Payee”), or order, the principal sum of up to Three Hundred Thousand Dollars
($300,000) 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 the Maker to such
account as the Payee may from time to time designate by written notice in accordance with the provisions of this Note. 
 1.
Principal. The principal balance of this Note shall be payable by the Maker on the earlier of: (i) September 30, 2021 or (ii) the date on which Maker consummates an initial public offering of its securities. The principal
balance may be prepaid at any time. Under no circumstances shall any individual, including but not limited to any officer, director, employee or shareholder of the Maker, be obligated personally for any obligations or liabilities of the Maker
hereunder. 
 2. Interest. No interest shall accrue on the unpaid principal balance of this Note. 

3. Drawdown Requests. Maker and Payee agree that Maker may request up to Three Hundred Thousand Dollars ($300,000) for costs reasonably
related to Maker’s initial public offering of its securities. The principal of this Note may be drawn down from time to time prior to the earlier of: (i) September 30, 2021 or (ii) the date on which Maker consummates an initial
public offering of its securities, upon written 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 five (5) business days after receipt of a Drawdown Request; provided, however, that the maximum amount of drawdowns collectively
under this Note is Three Hundred Thousand Dollars ($300,000). Once an amount is drawn down under this Note, it shall not be available for future Drawdown Requests even if prepaid. No fees, payments or other amounts shall be due to Payee in
connection with, or as a result of, any Drawdown Request by Maker. Notwithstanding the foregoing, 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 attorneys’ fees, and then to the reduction of 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”):

five (5) business days of the date specified above.
