**NOW, THEREFORE**, pursuant to <u>Section 10.1(a)(i)</u> of the Trust Agreement, the Trustee and the Sponsor hereby amend the Trust Agreement as set forth below.

**ARTICLE I AMENDMENTS**

SECTION 1.1 *Amendments*.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) <u>Section 1.2</u> of the Trust Agreement is hereby amended and restated in its entirety to read as follows:

SECTION 1.2 *Name*.

The name of the Trust is "Grayscale Sui Staking ETF" in which name the Trustee and the Sponsor shall cause the Trust to carry out its purposes as set forth in <u>Section 1.5</u>, make and execute contracts and other instruments in the name and on behalf of the Trust and sue and be sued in the name and on behalf of the Trust.

SECTION 6.8 *Expenses and Limitations Thereon*.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) <u>Sponsor's Fee</u>.
