PROMISSORY NOTE





	 	(Secondment)	 
	Principal Amount: Up to $400,000	 	Dated as of September 7, 2021


 


Silver Sustainable Solutions Corp., a Delaware corporation (the “Maker”),
promises to pay to the order of Metric Finance Holdings III, LLC, or its registered assigns or successors in interest (the “Payee”),
the principal sum of four hundred thousand U.S. dollars
($400,000) or such lesser amount as shall have been advanced by Payee to Maker and shall remain unpaid under this Note upon the consummation
of an Initial Business Combination (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. To the extent drawn upon, as
set described in Section 2 below and as set forth on Schedule A, the principal balance of this Note shall be repaid to Payee
upon the date (the “Maturity Date”) on which the Maker consummates a merger, capital stock exchange, asset acquisition,
stock purchase, reorganization or similar business combination with one or more businesses (together, an “Initial Business Combination”);
provided, however, that in the event that the Maker does not consummate an Initial Business Combination, then any principal balance
remaining will be due when funds are released from Maker’s trust account and shall be paid out of funds held outside of the Maker’s
trust account available for distribution, if any.


 


2. Drawdown Requests. Maker and Payee agree
that Maker may request, from time to time, up to an aggregate of four hundred thousand U.S. dollars ($400,000) under this Note to be used
for costs and expenses related to Maker’s secondment arrangement with Payee. Principal of this Note may be drawn down from time
to time prior to the consummation of an Initial Business Combination 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 greater than one-hundred thousand dollars ($100,000)
per quarter (i.e., March 31, June 30, September 30 and December 31), with such amounts to be evidenced on Schedule A hereto. Payee
acknowledges that all amounts drawn under this Note shall accrue only when such amounts are actually drawn upon, as reflected on Schedule
A, with such amounts to become due and upon each Maturity Date. 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 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 thirty (30) days following its Initial Business Combination.


 


(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 4(a) hereof, Payee may, by written notice to Maker, declare this Note to be immediately due and payable, whereupon
the unpaid principal amount of this Note, and all other amounts payable hereunder, shall become immediately due and payable without presentment,
demand, protest or other notice of any kind, all of which are hereby expressly waived, anything contained herein or in the documents evidencing
the same to the contrary notwithstanding.


 


(b) Upon the occurrence of an Event of Default
specified in Sections 4(b) or 4(c), the unpaid principal balance of this Note, and all other sums payable with regard to this Note, shall

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, or 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.

11. Severability. Any provision contained
in this Note which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability
in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.


 


12. Trust Waiver. Notwithstanding anything
herein to the contrary, the Payee hereby waives any and all right, title, interest or claim of any kind (“Claim”) in
or to any distribution of or from the trust account to be established in which the proceeds of the initial public offering (the “IPO”)
conducted by the Maker (including the deferred underwriting discounts and commissions) and the proceeds of the sale of the warrants issued
in a private placement to occur prior to the effectiveness of the IPO are to be deposited, as described in greater detail in the registration
statement and prospectus to be filed with the Securities and Exchange Commission in connection with the IPO, and hereby agrees not to
seek recourse, reimbursement, payment or satisfaction for any Claim against the trust account for any reason whatsoever.
