Dear Mr. Silver:

This will confirm the agreement between Guggenheim Securities, LLC (“Guggenheim”) and Silver Sustainable Solutions Corp. (the “Host”) to second Crosby Fish (the “Secondee”) to the Host on the terms set forth below.

Secondment

Secondee will be made available to support the Host beginning as of the date set forth above (the “Effective Date”) and concluding on the date that is six months after the Effective Date (or any extension thereof that may be agreed to by and between Guggenheim, the Host and the Secondee) (the “Secondment Period”). For each full month that the Secondee provides services to the Host, the Host agrees to pay Guggenheim a fee of up to $33,333 (the “Secondment Fee”) for the Secondee’s services, which shall be accrued and paid on a quarterly basis. Any Secondment Fee shall be prorated for any partial months. The Secondment Period may be terminated by either party on ten days written notice and may be extended if mutually agreed in writing by Guggenheim and the Host.

All services provided by Secondee will be provided either remotely or in an office space of, or arranged by, the Host. Secondee will be seconded to the Host on a full-time basis, will work under the supervision of the Host which will determine the matters to which Secondee is assigned will oversee his work. Both parties agree to inform the other as soon as reasonably practicable of any significant matter that may arise during the Secondment Period relating to the Secondee.

Conflicts of Interest

During the Secondment Period, the Secondee will not work in any Guggenheim office or on any Guggenheim matters, nor will he have access to Guggenheim systems except for limited e-mail access and third-party data platforms as needed for due diligence purposes. During and after the Secondment Period, Secondee will have obligations to Guggenheim and the Host with respect to Confidential Information, as that term and such obligations are described in Appendix A hereto, excerpts from the Secondment Agreement between Secondee and Guggenheim concerning Confidential Information. During the Secondment Period, Secondee shall owe a duty of loyalty exclusively to the Host, notwithstanding that he will remain an employee of Guggenheim.

Employment of Secondee

The Host acknowledges and agrees that Secondee is and shall remain during the Secondment Period an employee of Guggenheim, which shall continue to provide compensation, subject to applicable withholdings, and all applicable benefits and coverages associated with Secondee’s employment with Guggenheim including, but not limited to, health care coverage and workers compensation coverage. Secondee shall also continue to be eligible for leave and vacation as per Guggenheim policies, but shall coordinate logistics with the Host.

During the Secondment Period, Guggenheim agrees to indemnify and hold the Host harmless for any claims for unpaid wages, bonuses, fringe benefits or other compensation Secondee could bring based on monies or benefits owed by Guggenheim. Guggenheim will not, however, be responsible for compensation (if any) promised by the Host to which Guggenheim has not agreed. The Host acknowledges that it is not authorized to make representations or agreements about compensation to Secondee, nor shall it make any payments to Secondee with respect to the Secondment Period without Guggenheim’s approval. Notwithstanding the foregoing, the Host shall be responsible for reimbursing to the Secondee any reasonable travel, accommodation and other expenses, if any, wholly, exclusively and necessarily incurred by Secondee during the Secondment Period provided such expenses are incurred and documented in a manner specified by Host.

To the extent any claims are asserted against Guggenheim or against Secondee in connection with his work on behalf of the Host during the Secondment Period, the Host agrees to defend, indemnify and hold Guggenheim and Secondee harmless from and against any such claims and all associated costs and expenses to the extent that the Host would defend or indemnify any employee of Host against such claims.

Miscellaneous

This agreement represents the entire agreement between Guggenheim and the Host in connection with the Secondee and neither is relying on any statements or representations not set out herein. This agreement shall be governed by the laws of the State of New York, without regard to conflict of law provisions.

We are pleased to be able to offer this arrangement. If you accept the terms of this Agreement, please execute and return this letter to me.

Sincerely,

Appendix A
