Spring Valley Acquisition Sponsor, LLC (the “Sponsor”) shall take steps directly or indirectly to make
available to the Company certain office space, secretarial and administrative services as may be required by the Company from time
to time, situated at 2100 McKinney Ave, Suite 1675, Dallas, Texas 75201 (or any successor location). In exchange therefore, the
Company shall pay Sponsor or one of its affiliates a sum of $10,000 per month on the Effective Date and continuing monthly thereafter
until the Termination Date. Sponsor hereby agrees that it does not have any right, title, interest or claim of any kind (a “Claim”)
in or to any monies that may be set aside in a trust account (the “Trust Account”) that may be established

whatsoever.
