 of owning Shares.

This discussion is based on the Code, administrative pronouncements, judicial decisions and final, temporary and proposed Treasury regulations as of the date hereof, changes to any of which subsequent to the date hereof may affect the tax consequences described herein. For the avoidance of doubt, this summary does not discuss any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction.

Shareholders are urged to consult their tax advisers about the application of the U.S. federal income tax laws to their particular situations, as well as any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction.

Tax Treatment of the Trust

The Sponsor intends to take the position that the Trust is properly treated as a grantor trust for U.S. federal income tax purposes. Assuming that the Trust is a grantor trust, the Trust will not be subject to U.S. federal income tax. Rather, if the Trust is a grantor trust, each beneficial owner of Shares will be treated as directly owning its pro rata share of the Trust’s assets and a pro rata portion of the Trust’s income, gains, losses and deductions will “flow through” to each beneficial owner of Shares.

Although not free from doubt due to the lack of authority directly addressing certain aspects of the Trust’s affairs, and based on the assumption that the Staking Condition will be satisfied before the Trust engages in any staking activity, in the opinion of Davis Polk the Trust should be classified as a “grantor trust” for U.S. federal income tax purposes. An opinion of counsel is not binding on the IRS or any court, and there are significant uncertainties regarding the application of existing authorities to certain aspects of SUI and the Trust. Accordingly, there can be no complete assurance that the Trust will be treated as a grantor trust for those purposes.

In particular, if the Staking Condition is satisfied and the Trust engages in Staking activity, the Sponsor intends to continue to take the position that the Trust is properly treated as a grantor trust for U.S. federal income tax purposes and that any Staking activity undertaken by the Trust in compliance with the opinion, ruling or other guidance relied upon to satisfy the Staking Condition will not prevent the Trust from continuing to qualify as a grantor trust for such purposes. However, due to the uncertainty regarding the ability

of a grantor trust to engage in Staking activities, there can be no assurance that the IRS or any court would agree with
