Guggenheim Special Acquisition Corp. I., a Cayman Islands exempted
company and blank check company (the “Maker”), promises to pay to the order of Guggenheim Partners Holdings,
LLC, or its registered assigns or successors in interest (the “Payee”), or order, the principal sum of three
hundred thousand U.S. dollars ($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 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 on the earlier of: (i) December 31, 2021 or (ii) the date on which Maker consummates an initial public offering of its

2. Drawdown Requests. Maker and Payee agree that Maker
may request, from time to time, up to Three Hundred Thousand Dollars ($300,000) in draw downs under this Note to be used for costs

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

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

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.
