Note 4 – Service Providers and Related Party Agreements

The Trustee

CSC Delaware Trust Company, a Delaware trust company, acts as the Trustee of the Trust as required to create a Delaware statutory trust in accordance with the Trust Agreement and the DSTA. Under the Trust Agreement, the duties of the Trustee are limited to (i) accepting legal process served on the Trust in the State of Delaware and (ii) at the direction of the Sponsor, the execution of any certificates required to be filed with the Secretary of State of the State of Delaware which the Trustee is required to execute under the DSTA.

The Sponsor

Invesco Capital Management LLC is the Sponsor of the Trust. The Sponsor arranged for the creation of the Trust and is responsible for the ongoing registration of the Shares for their public offering, the listing of Shares on the Exchange and valuing the SOL held by the Trust. The Sponsor is a limited liability company formed in the state of Delaware on February 7, 2003, and is a wholly-owned subsidiary of Invesco Ltd. Invesco Ltd. and its subsidiaries, including the Sponsor, are an independent global investment management group.

The Trust pays the Sponsor a unified fee (the “Sponsor Fee”) in an amount equal to 0.25% per annum of the daily total net assets of the Trust as compensation for services performed under the Trust Agreement. The Trust’s only ordinary recurring expense is the Sponsor Fee. The Sponsor Fee is accrued daily and paid monthly in arrears on the first Business Day of the month in U.S. dollars, and is calculated by the Administrator. The Sponsor also paid the costs of the Trust’s organization.

To cover the Sponsor Fee, and extraordinary expenses not assumed by the Sponsor, the Sponsor or its delegate will cause the Trust (or its delegate) to instruct the Execution Agent to convert SOL held by the Trust into U.S. dollars. Extraordinary expenses

include, but are not limited to, taxes and governmental charges, any applicable brokerage commissions, financing fees, Solana network fees and similar transaction fees, expenses and costs of any extraordinary services performed by the Sponsor (or any other service provider) on behalf of the Trust to protect the Trust or the interests of Shareholders (including, for example, in connection with any fork of the Solana blockchain), any indemnification of the Sponsor, Cash Custodian, Solana Custodian, Administrator or other agents, service providers or counterparties of the Trust and extraordinary legal fees and expenses, including any legal fees and expenses incurred in connection with litigation, regulatory enforcement or investigation matters. The NAV of the Trust and the number of SOL represented by a Share will decline each time the Trust accrues the Sponsor Fee or any Trust expenses not assumed by the Sponsor. The Trust is not responsible for paying any costs associated with the transfer of SOL to or from the Trust in connection with paying the Sponsor Fee or in connection with creation and redemption transactions.

The Administrator

BNYM serves as the Trust’s Administrator. Under the trust administration and accounting agreement, the Administrator provides necessary administrative, tax and accounting services and financial reporting for the maintenance and operations of the Trust, including calculating the NAV of the Trust, determining the net assets of the Trust, and calculating the size of the creation baskets.

The Transfer Agent

BNYM also serves as the Transfer Agent for the Trust. The Transfer Agent is responsible for (1) issuing and redeeming Shares in connection with creation and redemption transactions, (2) responding to correspondence by Shareholders and others relating to its duties, (3) maintaining Shareholder accounts and (4) making periodic reports to the Trust.

The Solana Custodian

Coinbase Custody Trust Company, LLC serves as the Trust’s Solana Custodian. Under the Solana Custody Agreement, the Solana Custodian is responsible for (1) safekeeping all of the SOL owned by the Trust, (2) opening an account that holds the Trust’s SOL and (3) facilitating the transfer of SOL required for the operation of the Trust, as directed by the Sponsor. The Solana Custodian is chartered as a limited purpose trust company by the New York State Department of Financial Services (“NYSDFS”) and is authorized by the NYSDFS to provide digital asset custody services. The Solana Custodian is a wholly-owned subsidiary of Coinbase Global, Inc.

Under the Cash Custody Agreement, the Cash Custodian is responsible for holding the Trust's cash in connection with creation and redemption transactions effected in cash. The Cash Custodian is a New York state-chartered bank and a member of the Federal Reserve System.

The Staking Provider

Galaxy Blockchain Infrastructure LLC, an affiliate of the Execution Agent (as defined below), serves as a Staking Provider with respect to the Trust’s SOL. The Staking Provider stakes the Trust’s SOL as the node operator and will operate a validator by which the Trust’s SOL is staked. The Staking Provider will perform its staking services in collaboration with the Solana Custodian, as the SOL is staked directly from the Trust’s account with the Solana Custodian.

The Marketing Agent

Invesco Distributors, Inc. (the “Marketing Agent”) is responsible for: (1) working with the Transfer Agent to review and approve, or reject, purchase and redemption orders of Creation Baskets placed by Authorized Participants with the Transfer Agent; and (2) reviewing and approving the marketing materials prepared by the Trust for compliance with applicable SEC and Financial Industry Regulatory Authority advertising laws, rules, and regulations.

The Execution Agent

The Sponsor has entered into an agreement with Galaxy Digital Funds LLC, a subsidiary of Galaxy Digital LP (“Galaxy”), to serve as Execution Agent. The Trust from time to time will be required to sell SOL in such quantities as necessary to permit payment of the Sponsor Fee and any Trust expenses and liabilities not assumed by the Sponsor. The Sponsor has engaged the Execution Agent to sell SOL on the Trust’s behalf in such circumstances. The Sponsor or its delegate will cause the Trust (or its delegate) to instruct the Execution Agent to sell SOL at approximately the price at which it is valued by the Trust and in the smallest amounts required to permit such payments as they become due, with the intention of minimizing the Trust’s holdings of assets other than SOL. Accordingly, the amount of SOL to be sold may vary from time to time depending on the level of the Trust’s expenses and liabilities and the market price of SOL. The Trust also may utilize the services of the Execution Agent to purchase or sell SOL in connection with cash creations and redemptions.

In addition, as part of this agreement, the Execution Agent has agreed to co-brand and co-market the Trust, and the Sponsor has licensed the use of certain Galaxy trademarks, service marks and trade names in connection with the Trust.

Galaxy is a subsidiary of Galaxy Digital Holdings LP (“Galaxy Holdings”). Galaxy Digital Holdings Ltd., which holds a limited partner interest in Galaxy Holdings, is listed on the Toronto Stock Exchange under the symbol “GLXY.”
