Each of the parties hereto, by entering into this Trust Agreement, (i) expresses its intention that the Shares will qualify under applicable tax law as interests in a grantor trust which holds the Trust Estate, (ii) agrees that it will file its own U.S. federal, state and local income, franchise and other tax returns in a manner that is consistent with clause ‎(i) of this ‎Section 1.6 and with the classification of the Trust as a grantor trust, unless required otherwise by a final “determination” within the meaning of Section 1313(a) of the Code, and (iii) agrees to use reasonable efforts to notify the Sponsor promptly upon a receipt of any notice from any taxing authority having jurisdiction over such holders of Shares with respect to the treatment of the Shares as anything other than interests in a grantor trust.

Section 1.7 Legal Title. Legal title to all of the Trust Estate shall be vested in the Trust as a separate legal entity; provided, however, that if applicable law in any jurisdiction requires legal title to any portion of the Trust Estate to be vested otherwise, the Sponsor may cause legal title to such portion of the Trust Estate to be held by or in the name of the Sponsor or any other Person (other than a Shareholder) as nominee.

Article II

THE TRUSTEE

Section 2.1 Term; Resignation; Removal.

(a) CSC Delaware Trust Company has been appointed and hereby agrees to serve as the Trustee of the Trust. The Trust shall have only one Trustee unless otherwise determined by the Sponsor. The Trustee shall serve until such time as the Trust is terminated or if the Sponsor removes the Trustee or the Trustee resigns. The Trustee is appointed to serve as the trustee of the Trust in the State of Delaware and shall at all times satisfy the requirements of Section 3807(a) of the Delaware Trust Statute and be authorized to exercise corporate trust powers under the laws of Delaware, having a combined capital, surplus and undivided profits of at least $50,000,000 and subject to supervision or examination by federal or state authorities. If the Trustee publishes reports of condition at least annually, pursuant to law or to the requirements of the

aforesaid supervising or examining authority, then for the purposes of this ‎Article II the combined capital, surplus and undivided profits of the Trustee shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. In case at any time the Trustee shall cease to be eligible to serve as trustee of the Trust in accordance with the provisions of this ‎Section 2.1, the Trustee shall resign promptly in the manner and with the effect specified in this ‎Article II. The Trustee may have normal banking and trust relationships with the Sponsor and their respective Affiliates; provided that none of (i) the Sponsor, (ii) any Person involved in the organization or operation of the Sponsor or the Trust or (iii) any Affiliate of any of them may be the Trustee hereunder. The Trust shall have at least one trustee with a principal place of business in Delaware. It is understood and agreed by the parties hereto that the Trustee shall have none of the duties or liabilities of the Sponsor and shall have no obligation to supervise or monitor the Sponsor or otherwise manage the Trust.

(b) The Trustee is permitted to resign upon at least one hundred and eighty (180) days’ notice to the Sponsor upon which date such resignation shall be effective.

(c) If at any time the Trustee shall cease to be eligible to serve as trustee of the Trust in accordance with the provisions of this Trust Agreement, or if at any time the Trustee shall become incapable of acting, or shall be adjudged bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then the Sponsor may remove the Trustee and appoint a successor trustee by written instrument, in duplicate, which instrument shall be delivered to the Trustee so removed and the successor trustee. The Sponsor may at any time, upon sixty (60) days’ prior notice to the Trustee, remove the Trustee and appoint a successor trustee by written instrument or instruments, in triplicate, signed by the Sponsor or its attorney-in-fact duly authorized, one complete set of which instruments shall be delivered to the Trustee so removed and one complete set to the successor so appointed.

Section 2.2 Powers. Except to the extent expressly set forth in ‎Section 1.3 and this ‎Article II, the duty and authority to manage the affairs of the Trust is vested in the Sponsor, which duty and authority the Sponsor may further delegate as provided herein, all pursuant to Section 3806(b)(7) of the Delaware Trust Statute. The duties of the Trustee shall be limited to (i) accepting legal process served on the Trust in the State of Delaware, (ii) 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 Section 3811 of the Delaware Trust Statute, and (iii) any other duties specifically allocated to the Trustee in this Trust Agreement. For the avoidance of doubt, the duties of the Trustee will in no event be deemed to include any duties related to Staking or the making of investment or discretionary decisions. The Trustee shall provide prompt notice to the Sponsor of its performance of any of the foregoing. The Sponsor shall reasonably keep the Trustee informed of any actions taken by the Sponsor with respect to the Trust that would reasonably be expected to affect the rights, obligations or liabilities of the Trustee hereunder or under the Delaware Trust Statute.

Section 2.3 Compensation and Expenses of the Trustee. The Trustee shall be entitled to receive from the Sponsor, as a Sponsor-paid Expense, reasonable compensation for its services hereunder as set forth in a separate fee agreement and shall be entitled to be reimbursed by the Sponsor on behalf of the Trust for reasonable out-of-pocket expenses incurred by it in the

performance of its duties hereunder, including without limitation, the reasonable compensation, out-of-pocket expenses and disbursements of counsel, any experts and such other agents as the Trustee may employ in connection with the exercise and performance of its rights and duties hereunder (together, the “Trust Expenses”). To the extent that the Sponsor fails to pay the Trust Expenses, the Trust will be responsible for such Trust Expenses. Though it is not intended that the Trustee will receive or handle Trust funds in the ordinary course, to the extent that the Trustee does receive such funds the following shall provide notice and authorization that the Trustee may earn compensation in the form of short-term interest (“float”) on items like uncashed distribution checks (from the date issued until the date cashed), funds that the Trustee is directed not to invest, deposits awaiting investment direction or received too late to be invested overnight in previously directed investments.

Section 2.4 Indemnification.

(a) The Trust hereby agrees to be primary obligor and shall indemnify, defend and hold harmless the Trustee and any of the officers, directors, employees and agents of the Trustee (the “Indemnified Persons”) from and against any and all losses, damages, liabilities, claims, actions, suits, costs, expenses, disbursements (including the reasonable fees and expenses of counsel and fees and expenses incurred in connection with enforcement of its indemnification rights hereunder), taxes and penalties of any kind and nature whatsoever (collectively, “Expenses”), to the extent that such Expenses arise out of or are imposed upon or asserted at any time against such Indemnified Persons with respect to the performance of this Trust Agreement, the creation, operation or termination of the Trust or the transactions contemplated hereby; provided, however, that the Trust shall not be required to indemnify any Indemnified Person for any Expenses which are a result of the willful misconduct, bad faith or gross negligence of an Indemnified Person. If the Trust shall have insufficient assets or improperly refuses to pay an Indemnified Person within sixty (60) days of a request for payment owed hereunder, the Sponsor shall, as secondary obligor, compensate or reimburse the Trustee or indemnify, defend and hold harmless an Indemnified Person as if it were the primary obligor hereunder; provided, however, that the Sponsor shall not be required to indemnify any Indemnified Person for any Expenses which are a result of the willful misconduct, bad faith or gross negligence of an Indemnified Person. To the fullest extent permitted by law and by the requirement for treatment of the Trust as a grantor trust for tax purposes, Expenses to be incurred by an Indemnified Person shall, from time to time, be advanced by, or on behalf of, the Sponsor prior to the final disposition of any matter upon receipt by the Sponsor of an undertaking by, or on behalf of, such Indemnified Person to repay such amount if it shall be determined that the Indemnified Person is not entitled to be indemnified under this Trust Agreement.

(b) As security for any amounts owing to the Trustee hereunder, the Trustee shall have a lien against the Trust property, which lien shall be prior to the rights of the Sponsor or any other Shareholder. The obligations of the Sponsor and the Trust to indemnify the Indemnified Persons under this ‎Section 2.4 shall survive the termination of this Trust Agreement.

Section 2.5 Successor Trustee. Upon the resignation or removal of the Trustee, the Sponsor shall appoint a successor Trustee by delivering a written instrument to the outgoing Trustee. Any successor Trustee must satisfy the requirements of Section 3807 of the Delaware Trust Statute. The successor Trustee shall become fully vested with all of the rights, powers, duties

and obligations of the outgoing Trustee under this Trust Agreement, with like effect as if originally named as Trustee, and the outgoing Trustee shall be discharged of its duties and obligations under this Trust Agreement. Any business entity into which the Trustee may be merged or converted or with which it may be consolidated, or any entity resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any entity succeeding to all or substantially all of the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, to the fullest extent permitted by law without the execution or filing of any paper or any further act on the part of any of the parties hereto.

Section 2.6 Liability of Trustee. Except as otherwise provided in this ‎Article II, in accepting the trust created hereby, CSC Delaware Trust Company acts solely as Trustee hereunder and not in its individual capacity, and all Persons having any claim against CSC Delaware Trust Company by reason of the transactions contemplated by this Trust Agreement and any other agreement to which the Trust is a party shall look only to the Trust Estate for payment or satisfaction thereof. The Trustee shall not be liable or accountable hereunder to the Trust or to any other Person or under any other agreement to which the Trust is a party, except for the Trustee’s own fraud, gross negligence, bad faith or willful misconduct. In particular, but not by way of limitation:

its capacity as Trustee and individually) security or indemnity satisfactory to it against the costs, expenses and liabilities that may be incurred by CSC Delaware Trust Company (including, without limitation, the reasonable fees and expenses of its counsel) therein or thereby;

(i) Notwithstanding anything contained herein to the contrary, the Trustee shall not be required to take any action in any jurisdiction other than in the State of Delaware if the taking of such action will (i) require the consent or approval or authorization or order of, or the giving of notice to, or the registration with or taking of any action in respect of, any state or other governmental authority or agency of any jurisdiction other than the State of Delaware, (ii) result in any fee, tax or other governmental charge becoming payable by the Trustee under the laws of any jurisdiction or any political subdivision thereof other than the State of Delaware or (iii) subject the Trustee to personal jurisdiction, other than in the State of Delaware, for causes of action arising from personal acts unrelated to the consummation of the actions of the Trustee contemplated by this Trust Agreement;

(j) To the extent that, at law or in equity, the Trustee has duties (including fiduciary duties) and liabilities relating thereto to the Trust, the Shareholders or any other Person, the Trustee, acting under this Trust Agreement, shall not be liable to the Trust, the Shareholders or any other Person for its good faith reliance on the provisions of this Trust Agreement, and the provisions of this Trust Agreement, to the extent that they restrict or eliminate the duties and liabilities of the Trustee otherwise existing at law or in equity are agreed by the parties hereto to replace such other duties and liabilities of the Trustee; and

(k) The Trustee shall not be liable for punitive, exemplary, consequential or similar damages for a breach of the Trust Agreement under any circumstances.

Section 2.7 Reliance; Advice of Counsel.

(a) In the absence of bad faith, the Trustee may conclusively rely upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Trust Agreement in determining the truth of the statements and the correctness of the opinions contained therein, and shall incur no liability to anyone in acting or not acting on any signature, instrument, notice, resolution, request, consent, order, certificate, report, opinion, bond or other document or paper believed by it to be genuine and believed by it to be signed by the proper party or parties and need not investigate any fact or matter pertaining to, or contained in, any such document; provided, however, that the Trustee shall have examined any certificates and opinions so as to reasonably determine compliance of such certificates and opinions with the requirements of this Trust Agreement. The Trustee may accept a certified copy of a resolution of the board of directors or other governing body of any corporate party as conclusive evidence that such resolution has been duly adopted by such body and that such resolution is in full force and effect. As to any fact or matter the method of the determination of which is not specifically prescribed in this Trust Agreement, the Trustee may for all purposes hereof rely on a certificate, signed by the president, any vice president, the treasurer or any other authorized officers of the relevant party, as to such fact or matter, and such certificate shall constitute full protection to the Trustee for any action taken or omitted to be taken by it in good faith in reliance thereon.

(b) In the exercise or administration of the Trust hereunder and in the performance of its duties and obligations under this Trust Agreement, the Trustee, at the expense of the Trust (i) may act directly or through its agents, attorneys, custodians or nominees pursuant to agreements entered into with any of them, and the Trustee shall not be liable for the conduct or misconduct of such agents, attorneys, custodians or nominees if such agents, attorneys, custodians or nominees shall have been selected by the Trustee with reasonable care and (ii) may consult with counsel, accountants and other skilled professionals to be selected with reasonable care by it.

Subject to the foregoing, neither the Sponsor nor any other Covered Person shall be personally liable for the return or repayment of all or any portion of the SUI transferred, or the purchase price otherwise paid, by a Shareholder for its Shares, it being expressly agreed that any such return made pursuant to this Trust Agreement shall be made solely from the assets of the Trust without any rights of contribution from the Sponsor or any other Covered Person. A Covered Person shall not be liable for the conduct or misconduct of any delegate selected by the Sponsor with reasonable care.

Section 6.6 Fiduciary Duty.

(a) To the extent that, at law or in equity, the Sponsor has duties (including fiduciary duties) and liabilities relating thereto to the Trust, the Shareholders or any other Person, the Sponsor acting under this Trust Agreement shall not be liable to the Trust, the Shareholders or any other Person for its good faith reliance on the provisions of this Trust Agreement subject to the standard of care set forth in ‎Section 6.5 herein. The provisions of this Trust Agreement, to the extent that they restrict or eliminate the duties and liabilities of the Sponsor otherwise existing at law or in equity are agreed by the parties hereto to replace such other duties and liabilities of the Sponsor. To the fullest extent permitted by law, no Person other than the Sponsor and the Trustee shall have any duties (including fiduciary duties) or liabilities at law or in equity to the Trust, the Shareholders or any other Person.

(b) Unless otherwise expressly provided herein, (i) whenever a conflict of interest exists or arises between the Sponsor or any of its Affiliates, on the one hand, and the Trust, any Shareholder or any other Person, on the other hand; or (ii) whenever this Trust Agreement or any other agreement contemplated herein provides that the Sponsor shall act in a manner that is, or provides terms that are, fair and reasonable to the Trust, any Shareholder or any other Person, the Sponsor shall resolve such conflict of interest, take such action or provide such terms, considering in each case the relative interest of each party (including its own interest) to such conflict, agreement, transaction or situation and the benefits and burdens relating to such interests, any customary or accepted industry practices, and any applicable generally accepted accounting practices or principles. In the absence of bad faith by the Sponsor, the resolution, action or terms so made, taken or provided by the Sponsor shall not constitute a breach of this Trust Agreement or any other agreement contemplated herein or of any duty or obligation of the Sponsor at law or in equity or otherwise.

(c) The Sponsor and any Affiliate of the Sponsor may engage in or possess an interest in profit-seeking or business ventures of any nature or description, independently or with others, whether or not such ventures are competitive with the Trust and the doctrine of corporate opportunity, or any analogous doctrine, shall not apply to the Sponsor. If the Sponsor acquires knowledge of a potential transaction, agreement, arrangement or other matter that may be an opportunity for the Trust, it shall have no duty to communicate or offer such opportunity to the Trust, and the Sponsor shall not be liable to the Trust or to the Shareholders for breach of any fiduciary or other duty by reason of the fact that the Sponsor pursues or acquires for, or directs such opportunity to, another Person or does not communicate such opportunity or information to the Trust. Neither the Trust nor any Shareholder shall have any rights or obligations by virtue of this Trust Agreement or the trust relationship created hereby in or to such independent ventures or the income or profits or losses derived therefrom, and the pursuit of such ventures, even if competitive with the purposes of the Trust, shall not be deemed wrongful or improper. Except to the extent expressly provided herein, the Sponsor may engage or be interested in any financial or other transaction with the Trust, the Shareholders or any Affiliate of the Trust or the Shareholders.

(d) To the fullest extent permitted by law and notwithstanding any other provision of this Trust Agreement or in any agreement contemplated herein or applicable provisions of law or equity or otherwise, whenever in this Trust Agreement a Person is permitted or required to make a decision (i) in its “sole discretion” or “discretion” or under a grant of similar authority or latitude, the Person shall be entitled to consider only such interests and factors as it desires, including its own interests, and shall have no duty or obligation to give any consideration to any interest of or factors affecting the Trust, the Shareholders or any other Person, or (ii) in its “good faith” or under another express standard, the Person shall act under such express standard and shall not be subject to any other or different standard. The term “good faith” as used in this Trust Agreement shall mean subjective good faith as such term is understood and interpreted under Delaware law.

(a) The Sponsor shall be indemnified by the Trust against any losses, judgments, liabilities, expenses and amounts paid in settlement of any claims sustained by it in connection with its activities for the Trust, provided that (i) the Sponsor was acting on behalf of,

or performing services for, the Trust and has determined, in good faith, that such course of conduct was in the best interests of the Trust and such liability or loss was not the result of fraud, gross negligence, bad faith, willful misconduct, or a material breach of this Trust Agreement on the part of the Sponsor and (ii) any such indemnification will be recoverable only from the Trust Estate. All rights to indemnification permitted herein and payment of associated expenses shall not be affected by the dissolution or other cessation of existence of the Sponsor, or the withdrawal, adjudication of bankruptcy or insolvency of the Sponsor, or the filing of a voluntary or involuntary petition in bankruptcy under Title 11 of the United States Code by or against the Sponsor.

(b) Notwithstanding the provisions of ‎Section 6.7(a) above, the Sponsor, any Authorized Participant and any other Person acting as a broker-dealer for the Trust shall not be indemnified for any losses, liabilities or expenses arising from or out of an alleged violation of U.S. federal or state securities laws unless (i) there has been a successful adjudication on the merits of each count involving alleged securities law violations as to the particular indemnitee and the court approves the indemnification of such expenses (including, without limitation, litigation costs), (ii) such claims have been dismissed with prejudice on the merits by a court of competent jurisdiction as to the particular indemnitee and the court approves the indemnification of such expenses (including, without limitation, litigation costs) or (iii) a court of competent jurisdiction approves a settlement of the claims against a particular indemnitee and finds that indemnification of the settlement and related costs should be made.

(c) The Trust shall not incur the cost of that portion of any insurance that insures any party against any liability, the indemnification of which is herein prohibited.

(d) Expenses incurred in defending a threatened or pending civil, administrative or criminal action suit or proceeding against the Sponsor shall be paid by the Trust in advance of the final disposition of such action, suit or proceeding, if (i) the legal action relates to the performance of duties or services by the Sponsor on behalf of the Trust; (ii) the legal action is initiated by a third party who is not a Shareholder or the legal action is initiated by a Shareholder and a court of competent jurisdiction specifically approves such advance; and (iii) the Sponsor undertakes to repay the advanced funds with interest to the Trust in cases in which it is not entitled to indemnification under this ‎Section 6.7.

(e) The term “Sponsor” as used only in this ‎Section 6.7 shall include, in addition to the Sponsor, any other Covered Person performing services on behalf of the Trust and acting within the scope of the Sponsor’s authority as set forth in this Trust Agreement.

(f) In the event the Trust is made a party to any claim, dispute, demand or litigation or otherwise incurs any loss, liability, damage, cost or expense as a result of or in connection with any Shareholder’s (or assignee’s) obligations or liabilities unrelated to Trust affairs, such Shareholder (or assignees cumulatively) shall indemnify, defend, hold harmless, and reimburse the Trust for all such loss, liability, damage, cost and expense incurred, including attorneys’ and accountants’ fees.

Section 6.8 Expenses and Limitations Thereon.

(a) Sponsor’s Fee.

(i) The Trust shall pay to the Sponsor a fee (the “Sponsor’s Fee”), payable in SUI (except as provided in ‎Section 6.8(a)(iv)), which shall accrue daily in U.S. Dollars at an annual rate of 2.5% of the NAV Fee Basis Amount of the Trust as of 4:00 p.m., New York time, on each day; provided that for a day that is not a Business Day, the calculation shall be based on the NAV Fee Basis Amount from the most recent Business Day, reduced by the accrued and unpaid Sponsor’s Fee for such most recent Business Day and for each day after such most recent Business Day and prior to the relevant calculation date. The amount of SUI payable in respect of each daily U.S. Dollar accrual shall be determined by reference to the same Reference Rate Price used to determine such accrual. The Sponsor’s Fee is payable to the Sponsor daily in arrears.

(ii) Except as provided in ‎Section 6.8(a)(iv), to cause the Trust to pay the Sponsor’s Fee, the Sponsor shall instruct the Custodian to withdraw from the SUI Account the number of SUI equal to the accrued but unpaid Sponsor’s Fee and transfer such SUI to the account designated by the Sponsor at such times as the Sponsor determines in its absolute discretion.

(iii) After the payment of the Sponsor’s Fee to the Sponsor, the Sponsor may elect to convert the SUI it receives into U.S. Dollars. The Shareholders acknowledge that the rate at which the Sponsor converts such SUI to U.S. Dollars may differ from the rate at which the Sponsor’s Fee was initially converted into SUI. The Trust shall not be responsible for any fees and expenses incurred by the Sponsor to convert SUI received in payment of the Sponsor’s Fee into U.S. Dollars.

(iv) If the Trust holds any Incidental Rights and/or IR Virtual Currency at any time, the Trust may pay the Sponsor’s Fee, in whole or in part, with such Incidental Rights and/or IR Virtual Currency by transferring such Incidental Rights and/or IR Virtual Currency to the Sponsor; provided that the Trust shall use Incidental Rights and/or IR Virtual Currency to pay the Sponsor’s Fee only if such transfer does not otherwise conflict with the terms of this Trust Agreement. In the case of Incidental Rights or IR Virtual Currency, such Incidental Rights or IR Virtual Currency shall be transferred at a value to be determined in good faith by the Sponsor. If the Trust pays the Sponsor’s Fee in Incidental Rights and/or IR Virtual Currency, in whole or in part, the amount of SUI that would otherwise have been used to satisfy such payment shall be correspondingly reduced.

(v) The Sponsor may, from time to time, temporarily waive all or a portion of the Sponsor’s Fee in its sole discretion.

(vi) As partial consideration for receipt of the Sponsor’s Fee, the Sponsor shall assume and pay all fees and other expenses incurred by the Trust in the ordinary course of its affairs, excluding taxes, but including: (A) the Marketing Fee, (B) the Administrator Fee, (C) the Custodian Fee, (D) the Transfer Agent fee, (E) the Trustee fee, (F) the fees and expenses related to the listing, quotation or trading of the Shares on any Secondary Market (including customary legal, marketing and audit fees and expenses) in an amount up to $600,000 in any given Fiscal Year, (G) ordinary course legal fees and expenses, (H) audit fees, (I) regulatory fees, including, if applicable, any fees relating to the registration of the Shares under the Securities Act or the Exchange Act, (J) printing and

mailing costs, (K) costs of maintaining the Trust’s website and (L) applicable license fees (each, a “Sponsor-paid Expense” and together, the “Sponsor-paid Expenses”), provided that any expense that qualifies as Additional Trust Expenses as set forth in ‎Section 6.8(b) shall be deemed to be Additional Trust Expenses and not a Sponsor-paid Expense.

(vii) In addition to the Sponsor’s Fee, and as partial consideration for the Sponsor’s facilitation of Staking, but only if (and, then, only to the extent that) the Staking Condition has been satisfied with respect thereto, the Sponsor shall be entitled to receive a fee (the “Sponsor’s Staking Fee”), payable in SUI, which shall accrue daily in U.S. Dollars in an amount calculated as a per annum percentage of any Native Staking Consideration received by the Trust, as may be directed by the Sponsor in its sole discretion and disclosed in the Trust’s Memorandum from time to time. The Sponsor’s Staking Fee is payable to the Sponsor daily in arrears.

(viii) The Sponsor may, from time to time, temporarily waive all or a portion of the Sponsor’s Staking Fee in its sole discretion

(b) Additional Trust Expenses.

(i) The Trust shall pay any expenses incurred by the Trust in addition to the Sponsor’s Fee and the Sponsor’s Staking Fee that are not Sponsor-paid Expenses, including, but not limited to, (A) taxes and governmental charges, (B) 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 in connection with any Incidental Rights or any IR Virtual Currency), (C) any indemnification of the Custodian, Administrator, or other agents, service providers or counterparties of the Trust, (D) the fees and expenses related to the listing, quotation or trading of the Shares on any Secondary Market (including legal, marketing and audit fees and expenses) to the extent exceeding $600,000 in any given Fiscal Year and (E) extraordinary legal fees and expenses, including any legal fees and expenses incurred in connection with litigation, regulatory enforcement or investigation matters (collectively, “Additional Trust Expenses”).

(ii) To cause the Trust to pay the Additional Trust Expenses, if any, the Sponsor or its delegates (A) shall instruct the Custodian to withdraw SUI from the SUI Account in such quantity as may be necessary to permit payment of such Additional Trust Expenses and (B) may either (x) cause the Trust (or its delegate) to convert such SUI into U.S. Dollars or other fiat currencies at the Actual Exchange Rate or (y) cause the Trust (or its delegate) to deliver such SUI in kind in satisfaction of such Additional Trust Expenses.

(iii) If the Trust holds any Incidental Rights and/or IR Virtual Currency at any time, the Trust may pay any Additional Trust Expenses, in whole or in part, with such Incidental Rights and/or IR Virtual Currency by entering into an agreement with the relevant payee and transferring such Incidental Rights and/or IR Virtual Currency to that payee at a value to be determined in good faith by the Sponsor; provided that the Trust shall use Incidental Rights and/or IR Virtual Currency to pay Additional Trust Expenses only if such transfer does not otherwise conflict with the terms of this Trust Agreement. In

the case of Incidental Rights or IR Virtual Currency, such Incidental Rights or IR Virtual Currency shall be transferred at a value to be determined in good faith by the Sponsor. If the Trust pays the Additional Trust Expenses in Incidental Rights and/or IR Virtual Currency, in whole or in part, the amount of SUI that would otherwise have been used to satisfy such payment shall be correspondingly reduced.

(c) The Sponsor or any Affiliate of the Sponsor may be reimbursed only for the actual cost to the Sponsor or such Affiliate of any expenses that it advances on behalf of the Trust for payment of which the Trust is responsible. In addition, payment to the Sponsor or such Affiliate for indirect expenses incurred in performing services for the Trust in its capacity as the Sponsor (or an Affiliate of the Sponsor) of the Trust, such as salaries and fringe benefits of officers and directors, rent or depreciation, utilities and other administrative items generally falling within the category of the Sponsor’s “overhead,” is prohibited.

(a) The Sponsor shall not cease to be a Sponsor of the Trust merely upon the occurrence of its making an assignment for the benefit of creditors, filing a voluntary petition in bankruptcy, filing a petition or answer seeking for itself any reorganization, arrangement, composition, readjustment, liquidation, dissolution or similar relief under any statute, law or regulation, filing an answer or other pleading admitting or failing to contest material allegations of a petition filed against it in any proceeding of this nature or seeking, consenting to or acquiescing in the appointment of a trustee, receiver or liquidator for itself or of all or any substantial part of its properties.

(b) To the fullest extent permitted by law, and on sixty (60) days’ prior written notice to the Shareholders of their right to vote thereon, if any such transaction is other than with an affiliated entity, nothing in this Trust Agreement shall be deemed to prevent the merger of the Sponsor with another corporation or other entity, the reorganization of the Sponsor into or with any other corporation or other entity, the transfer of all the capital stock of the Sponsor or the assumption of the rights, duties and liabilities of the Sponsor by, in the case of a merger,

reorganization or consolidation, the surviving corporation or other entity by operation of law. Without limiting the foregoing, none of the transactions referenced in the preceding sentence shall be deemed to be a voluntary withdrawal for purposes of ‎Section 6.9 or an Event of Withdrawal for purposes of ‎Section 12.1(a)(iv).

Article VII

THE SHAREHOLDERS

Section 7.1 No Management or Control; Limited Liability; Exercise of Rights through an Authorized Participant.

Section 7.3 Limitation of Liability.

(a) Except as provided in ‎Section 6.7(f) hereof, and as otherwise provided under Delaware law, the Shareholders shall be entitled to the same limitation of personal liability extended to stockholders of private corporations for profit organized under the General Corporation Law of Delaware and no Shareholder shall be liable for claims against, or debts of the Trust in excess of its Percentage Interest of the Trust Estate, except in the case of a Shareholder that is an Authorized Participant, in the event that the liability is founded upon misstatements or omissions contained in such Shareholder’s Authorized Participant Agreement. In addition, and subject to the exceptions set forth in the immediately preceding sentence, the Trust shall not make a claim against a Shareholder with respect to amounts distributed to such Shareholder or amounts received by such Shareholder upon redemption of such Shareholder’s Shares unless, under Delaware law, such Shareholder is liable to repay such amount.

(b) The Trust shall indemnify to the full extent permitted by law and the other provisions of this Trust Agreement, and to the extent of the Trust Estate, each Shareholder against any claims of liability asserted against such Shareholder solely because it is a beneficial owner of one or more Shares as a Shareholder.

(c) Every written note, bond, contract, instrument, certificate or undertaking made or issued by the Sponsor on behalf of the Trust shall give notice to the effect that the same was executed or made by or on behalf of the Trust and that the obligations of such instrument are not binding upon the Shareholders individually but are binding only upon the assets and property of the Trust, and no resort shall be had to the Shareholders’ personal property for satisfaction of any obligation or claim thereunder, and appropriate references may be made to this Trust Agreement and may contain any further recital that the Sponsor deems appropriate, but the omission thereof shall not operate to bind the Shareholders individually or otherwise invalidate any such note, bond, contract, instrument, certificate or undertaking. Nothing contained in this ‎Section 7.3 shall diminish the limitation on the liability of the Trust to the extent set forth in ‎Section 3.6 hereof.

Section 7.4 Derivative Actions. Subject to any other requirements of applicable law including Section 3816 of the Delaware Trust Statute, no Shareholder shall have the right, power or authority to bring or maintain a derivative action, suit or other proceeding on behalf of the Trust unless two or more Shareholders who (i) are not Affiliates of one another and (ii) collectively hold at least 10% of the outstanding Shares join in the bringing or maintaining of such action, suit or other proceeding.

AMENDMENT OF TRUST AGREEMENT; MEETINGS

Section 10.1 Amendments to the Trust Agreement.

(a) Amendment Generally.

(i) Except as otherwise specifically provided in this ‎Section 10.1, the Sponsor, in its sole discretion and without Shareholder consent, may amend or otherwise supplement this Trust Agreement by making an amendment, an agreement supplemental hereto, or an amended and restated declaration of trust and trust agreement. Any such restatement, amendment and/or supplement hereto shall be effective on such date as designated by the Sponsor in its sole discretion; provided that unless, (x) pursuant to a final “determination” within the meaning of Section 1313(a) of the Code, it shall have been established that the Trust is other than a grantor trust for U.S. federal income tax purposes, (y) (A) the proposed amendment should not cause the Trust to be treated as other than a grantor trust for U.S. federal income tax purposes and (B) the Sponsor shall have received a written opinion of a Tax Advisor to that effect or (z) the proposed amendment is necessary or desirable, as determined by the Sponsor in its reasonable discretion, to conform to any Tax Guidance setting forth, or relating to, the conditions under which a trust may engage in one or more forms of Staking while continuing to be classified as a grantor trust for U.S. federal income tax purposes, the Sponsor shall not be permitted to make any such restatement, amendment, or otherwise supplement this Trust Agreement, if such restatement, amendment or supplement could permit the Sponsor, the Trustee or any other Person to vary the investment of the Shareholders (within the meaning of Treasury Regulations Section 301.7701-4(c)) or could otherwise adversely affect the status of the Trust as a grantor trust for U.S. federal income tax purposes.

(ii) To the extent that a restatement, amendment or supplement to this Trust Agreement materially adversely affects the interests of the Shareholders as determined by the Sponsor in its sole discretion, such restatement, amendment or supplement shall not be effective any earlier than twenty (20) calendar days after receipt by the affected Shareholders of a notice provided by the Sponsor with respect to any such restatement, amendment or supplement of this Trust Agreement. Notice pursuant to this ‎Section 10.1(a)(ii) may be given by the Sponsor to the Shareholder by email or other

electronic transmission and shall be deemed given upon receipt without requirement of confirmation

(iii) In lieu of restating, amending or supplementing this Trust Agreement pursuant to ‎Section 10.1(a)(ii), the Sponsor may, in its sole discretion, condition any restatement, amendment and/or supplement to this Trust Agreement upon the approval of Shareholders holding Shares equal to at least a majority (over 50%) of the Shares (not including Shares held by the Sponsor and its Affiliates). In the Sponsor’s sole discretion, the Sponsor may, but is not obligated to, provide that a Shareholder shall be deemed to approve to a restatement, amendment or supplement of this Trust Agreement pursuant to this ‎Section 10.1(a)(iii) if the Sponsor has notified such Shareholder in writing of the proposed restatement, amendment or supplement and the Shareholder has not, within twenty (20) calendar days of such notice, notified the Sponsor in writing that the Shareholder objects to such modification or amendment. Notice pursuant to this ‎Section 10.1(a)(iii) may be given by the Sponsor to the Shareholder by email or other electronic transmission and shall be deemed given upon receipt without requirement of confirmation.

(b) Without limitation of the foregoing, the Sponsor may, without the approval of the Shareholders, amend the provisions of this Trust Agreement if the Trust is advised at any time by the Trust’s accountants or legal counsel that the amendments made are necessary to ensure that the Trust’s status as a grantor trust will be respected for U.S. federal income tax purposes.

(c) No amendment affecting the rights or duties of the Trustee shall be binding upon or effective against the Trustee unless consented to by the Trustee in writing. No amendment shall be made to this Trust Agreement without the consent of the Trustee if the Trustee reasonably believes that such amendment adversely affects any of its rights, duties or liabilities. The Trustee shall be under no obligation to execute any amendment to the Trust Agreement or to any agreement to which the Trust is a party until it has received an instruction letter from the Sponsor, in form and substance reasonably satisfactory to the Trustee (i) directing the Trustee to execute such amendment, (ii) representing and warranting to the Trustee that such execution is authorized and permitted by the terms of the Trust Agreement and (if applicable) such other agreement to which the Trust is a party and does not conflict with or violate any other agreement to which the Trust is a party and (iii) confirming that such execution and acts related thereto are covered by the indemnity provisions of the Trust Agreement in favor of the Trustee and do not adversely affect the Trustee.

(d) Upon amendment of this Trust Agreement, the Certificate of Trust shall also be amended, if required by the Delaware Trust Statute, to reflect such change. At the expense of the Sponsor, the Trustee shall execute and file any amendment to the Certificate of Trust if so directed by the Sponsor.

(e) To the fullest extent permitted by law, no provision of this Trust Agreement may be amended, waived or otherwise modified orally but only by a written instrument adopted in accordance with this ‎Section 10.1.

Section 10.2 Meetings of the Trust. Meetings of the Shareholders may be called by the Sponsor in its sole discretion. The Sponsor shall furnish written notice to all Shareholders thereof

of the meeting and the purpose of the meeting, which shall be held on a date, not less than ten (10) nor more than sixty (60) days after the date of mailing of said notice, at a reasonable time and place. Any notice of meeting shall be accompanied by a description of the action to be taken at the meeting. Shareholders may vote in person or by proxy at any such meeting.

Section 10.3 Action Without a Meeting. Any action required or permitted to be taken by Shareholders by vote may be taken without a meeting by written consent setting forth the actions so taken. Such written consents shall be treated for all purposes as votes at a meeting. If the vote or consent of any Shareholder to any action of the Trust or any Shareholder, as contemplated by this Trust Agreement, is solicited by the Sponsor, the solicitation shall be effected by notice to each Shareholder given in the manner provided in ‎Section 13.6. The vote or consent of each Shareholder so solicited shall be deemed conclusively to have been cast or granted as requested in the notice of solicitation, whether or not the notice of solicitation is actually received by that Shareholder, unless the Shareholder expresses written objection to the vote or consent by notice given in the manner provided in ‎Section 13.6 and actually received by the Trust within twenty (20) days after the notice of solicitation is sent. The Covered Persons dealing with the Trust shall be entitled to act in reliance on any vote or consent that is deemed cast or granted pursuant to this ‎Section 10.3 and shall be fully indemnified by the Trust in so doing. Any action taken or omitted in reliance on any such deemed vote or consent of one or more Shareholders shall not be void or voidable by reason of any communication made by or on behalf of all or any of such Shareholders in any manner other than as expressly provided in ‎Section 13.6.

Each Shareholder (and any assignee thereof) expressly agrees that in the event of his or her death, he or she waives on behalf of himself or herself and his or her estate, and he or she directs the legal representative of his or her estate and any person interested therein to waive the furnishing of any inventory, accounting or appraisal of the Trust Estate and any right to an audit or examination of the books of account for the Trust, except for such rights as are set forth in Article VIII hereof relating to the books of account and reports of the Trust.

Section 12.2 Distributions on Dissolution. Upon the dissolution of the Trust, the Sponsor (or in the event there is no Sponsor, such person (the “Liquidating Trustee”) as the majority in interest of the Shareholders may propose and approve) shall take full charge of the Trust Estate. Any Liquidating Trustee so appointed shall have and may exercise, without further authorization or approval of any of the parties hereto, all of the powers conferred upon the Sponsor under the terms of this Trust Agreement, subject to all of the applicable limitations, contractual and otherwise, upon the exercise of such powers, and provided that the Liquidating Trustee shall not have general liability for the acts, omissions, obligations and expenses of the Trust.

Section 12.3 Termination; Certificate of Cancellation.

Notwithstanding anything to the contrary contained in this Trust Agreement, the existence of the Trust as a separate legal entity shall continue until the filing of such certificate of cancellation.

Article XIII

MISCELLANEOUS

Section 13.1 Governing Law. The validity and construction of this Trust Agreement and all amendments hereto shall be governed by the laws of the State of Delaware, and the rights of all parties hereto and the effect of every provision hereof shall be subject to and construed according to the laws of the State of Delaware without regard to the conflict of laws provisions thereof;

provided, however, that causes of action for violations of U.S. federal or state securities laws shall not be governed by this ‎Section 13.1, and provided, further, that the parties hereto intend that the provisions hereof shall control over any contrary or limiting statutory or common law of the State of Delaware (other than the Delaware Trust Statute) and that, to the maximum extent permitted by applicable law, there shall not be applicable to the Trust, the Trustee, the Sponsor, the Shareholders or this Trust Agreement any provision of the laws (statutory or common) of the State of Delaware (other than the Delaware Trust Statute) pertaining to trusts that relate to or regulate in a manner inconsistent with the terms hereof: (a) the filing with any court or governmental body or agency of trustee accounts or schedules of trustee fees and charges, (b) affirmative requirements to post bonds for trustees, officers, agents, or employees of a trust, (c) the necessity for obtaining court or other governmental approval concerning the acquisition, holding or disposition of real or personal property, (d) fees or other sums payable to trustees, officers, agents or employees of a trust, (e) the allocation of receipts and expenditures to income or principal, (f) restrictions or limitations on the permissible nature, amount or concentration of trust investments or requirements relating to the titling, storage or other manner of holding of trust assets or (g) the establishment of fiduciary or other standards or responsibilities or limitations on the acts or powers of trustees or managers that are inconsistent with the limitations on liability or authorities and powers of the Trustee or the Sponsor set forth or referenced in this Trust Agreement. Section 3540 of Title 12 of the Delaware Code shall not apply to the Trust. The Trust shall be of the type commonly called a “statutory trust,” and without limiting the provisions hereof, but subject to ‎Section 1.5 and ‎Section 1.6, the Trust may exercise all powers that are ordinarily exercised by such a statutory trust under Delaware law. Subject to ‎Section 1.5 and ‎Section 1.6, the Trust specifically reserves the right to exercise any of the powers or privileges afforded to statutory trusts and the absence of a specific reference herein to any such power, privilege or action shall not imply that the Trust may not exercise such power or privilege or take such actions.

Section 13.2 Provisions In Conflict With Law or Regulations.

(a) The provisions of this Trust Agreement are severable, and if the Sponsor shall determine, with the advice of counsel, that any one or more of such provisions (the “Conflicting Provisions”) are in conflict with the Code, the Delaware Trust Statute, the Securities Act, if applicable, or other applicable U.S. federal or state laws or the rules and regulations of any Secondary Market, the Conflicting Provisions shall be deemed never to have constituted a part of this Trust Agreement, even without any amendment of this Trust Agreement pursuant to this Trust Agreement; provided, however, that such determination by the Sponsor shall not affect or impair any of the remaining provisions of this Trust Agreement or render invalid or improper any action taken or omitted prior to such determination. No Sponsor or Trustee shall be liable for making or failing to make such a determination.

(b) If any provision of this Trust Agreement shall be held invalid or unenforceable in any jurisdiction, such holding shall not in any manner affect or render invalid or unenforceable such provision in any other jurisdiction or any other provision of this Trust Agreement in any jurisdiction.

Section 13.3 Counsel to the Trust. Counsel to the Trust may also be counsel to the Sponsor and its Affiliates. The Sponsor may execute on behalf of the Trust and the Shareholders any consent to the representation of the Trust that counsel may request pursuant to the New York

Rules of Professional Conduct or similar rules in any other jurisdiction (the “Rules”). The Shareholders acknowledge that the Trust has selected Davis Polk & Wardwell LLP as legal counsel to the Trust (“Trust Counsel”). Trust Counsel shall not represent any Shareholder in the absence of a clear and explicit agreement to such effect between the Shareholder and Trust Counsel (and that only to the extent specifically set forth in that agreement), and in the absence of any such agreement Trust Counsel shall owe no duties directly to a Shareholder. Each Shareholder agrees that, in the event any dispute or controversy arises between any Shareholder and the Trust, or between any Shareholder or the Trust, on the one hand, and the Sponsor (or an Affiliate thereof that Trust Counsel represents), on the other hand, that Trust Counsel may represent either the Trust or the Sponsor (or its Affiliate), or both, in any such dispute or controversy to the extent permitted by the Rules, and each Shareholder hereby consents to such representation. Each Shareholder further acknowledges that, regardless of whether Trust Counsel has in the past represented any Shareholder with respect to other matters, Trust Counsel has not represented the interests of any Shareholder in the preparation and negotiation of this Trust Agreement.

Section 13.4 Merger and Consolidation. Subject to the provisions of ‎Section 1.5 and ‎Section 1.6, the Sponsor may cause (i) the Trust to be merged into or consolidated with, converted to or to sell all or substantially all of its assets to, another trust or entity; (ii) the Shares of the Trust to be converted into beneficial interests in another statutory trust (or series thereof); or (iii) the Shares of the Trust to be exchanged for shares in another trust or company under or pursuant to any U.S. state or federal statute to the extent permitted by law. For the avoidance of doubt, subject to the provisions of ‎Section 1.5, the Sponsor, with written notice to the Shareholders, may approve and effect any of the transactions contemplated under (i), (ii) and (iii) above without any vote or other action of the Shareholders.

Section 13.5 Construction. In this Trust Agreement, unless the context otherwise requires, words used in the singular or in the plural include both the plural and singular and words denoting any gender include all genders. The title and headings of different parts are inserted for convenience and shall not affect the meaning, construction or effect of this Trust Agreement.

Section 13.6 Notices. All notices or communications under this Trust Agreement (other than notices of pledge or encumbrance of Shares, and reports and notices by the Sponsor to the Shareholders) shall be in writing and shall be effective upon personal delivery, or if sent by mail, postage prepaid, or if sent electronically, by email, or by overnight courier; and addressed, in each such case, to the address set forth in the books and records of the Trust or such other address as may be specified in writing, of the party to whom such notice is to be given, upon the deposit of such notice in the United States mail, upon transmission and electronic confirmation thereof or upon deposit with a representative of an overnight courier, as the case may be.

(a) Notwithstanding Sections ‎3.1, ‎3.3, ‎6.4(a) and ‎6.4(b), the Trust may, and the Sponsor shall have the power to cause the Trust to, create and issue Baskets in exchange for the receipt of cash from an Authorized Participant, but only if such creation and issuance is made in compliance with all of the following requirements:

(i) On the date and by no later than the specified time established for the settlement of such creation and issuance, which date and time shall be fixed, under procedures to be adopted by the Sponsor, on the date a Cash Order for creation is placed and accepted, the Trust shall have received and be simultaneously in possession of (A) from the applicable Liquidity Provider, SUI in an amount equal to the Total Basket Amount in respect of such Cash Order (the “Required Creation SUI”) and (B) from such Authorized Participant, cash in an amount at least equal to the full purchase price to be paid by the Trust to such Liquidity Provider in exchange for the Required Creation SUI (such purchase price, the “Required Creation Cash,” and such receipt and simultaneous possession of the Required Creation SUI and the Required Creation Cash at or prior to such specified time, the “Creation Settlement Condition”); provided, that such cash shall be held by the Trust in a non-interest bearing account established solely for the purpose of creating, issuing and redeeming Shares in accordance with the terms of this ‎Section 13.13;

(ii) If the Creation Settlement Condition is met with respect to such Cash Order, the Sponsor shall cause the Trust to deliver, promptly and in full satisfaction of the Trust’s obligations to the applicable Liquidity Provider and such Authorized Participant in respect of such Cash Order, (A) to the applicable Liquidity Provider, the Required Creation Cash, and (B) to such Authorized Participant, (x) the Shares comprising the Creation Baskets to be issued pursuant to such Cash Order and (y) to the extent that the amount of cash previously received by the Trust from such Authorized Participant in connection with such Cash Order exceeded the Required Creation Cash, the amount of such excess cash;

(iii) If, for any or no reason, the Creation Settlement Condition is not met with respect to such Cash Order, the Sponsor shall cause the Trust to return, promptly and in full satisfaction of the Trust’s obligations to the applicable Liquidity Provider and Authorized Participant in respect of such Cash Order, any and all cash and SUI previously received by the Trust in connection with such Cash Order to such Authorized Participant (in the case of cash) or Liquidity Provider (in the case of SUI); and

(iv) The Sponsor, such Authorized Participant and the applicable Liquidity Provider shall have agreed, as a condition to the participation in the consummation of such Cash Order, (A) to fully (and without exception) exculpate the Trust with respect to, and to irrevocably waive any and all claims against the Trust or the Trust Estate arising from or in connection with, such Cash Order and (B) to fully indemnify and

hold the Trust harmless against any failure by such person to perform its obligations in respect of such Cash Order.

(b) Notwithstanding ‎Section 5.2, during any time at which the Sponsor has authorized a redemption program, the Trust may, and the Sponsor shall have the power to cause the Trust to, redeem Baskets in exchange for the delivery of cash to an Authorized Participant, but only if such redemption is made in compliance with all of the following requirements:

(i) On the date and by no later than the specified time established for the settlement of such redemption, which date and time shall be fixed, under procedures to be adopted by the Sponsor, on the date a Cash Order for redemption is placed and accepted, the Trust shall have received and be simultaneously in possession of (A) from the applicable Liquidity Provider, cash proceeds from the sale of SUI in an amount equal to the Total Basket Amount in respect of such Cash Order (the “Required Redemption Cash”), provided, that such cash shall be held by the Trust in a non-interest bearing account established solely for the purpose of creating, issuing and redeeming Shares in accordance with the terms of this ‎Section 13.13, and (B) from such Authorized Participant, the Shares comprising the Baskets to be redeemed pursuant to such Cash Order (such Shares, the “Required Redemption Shares,” and such receipt and simultaneous possession of the Required Redemption Cash and the Required Redemption Shares at or prior to such specified time, the “Redemption Settlement Condition”);

(ii) If the Redemption Settlement Condition is met with respect to such Cash Order, the Sponsor shall cause the Trust to deliver, promptly and in full satisfaction of the Trust’s obligations to the applicable Liquidity Provider and such Authorized Participant in respect of such Cash Order, (A) to the applicable Liquidity Provider, SUI in an amount equal to the Total Basket Amount in respect of such Cash Order, and (B) to such Authorized Participant, the Required Redemption Cash;

(iii) If, for any or no reason, the Redemption Settlement Condition is not met with respect to such Cash Order, the Sponsor shall cause the Trust to return, promptly and in full satisfaction of the Trust’s obligations to the applicable Liquidity Provider and Authorized Participant in respect of such Cash Order, any and all cash and Shares previously received by the Trust in connection with such Cash Order to such Authorized Participant (in the case of Shares) or Liquidity Provider (in the case of cash); and

(c) The Sponsor from time to time may, but shall have no obligation to, modify or supplement the requirements set forth in ‎Section 13.13(a) and ‎Section 13.13(b), but only if the Sponsor, with advice of counsel, has determined that creating or redeeming Shares (as the case

may be) pursuant to such modified or supplemented requirements should not cause the Trust to be treated other than as a grantor trust for U.S. federal income tax purposes.

(d) By the purchase and acceptance or other lawful delivery, acceptance or holding of the Shares, the Shareholders shall be deemed to have acknowledged and agreed that any action taken in the manner contemplated by this ‎Section 13.13 shall be permitted under ‎Section 1.5 and ‎Section 6.4(p). For the avoidance of doubt, the definitions of any defined terms used in this Trust Agreement shall be deemed modified or supplemented to the extent necessary for the Sponsor and the Trust to effectuate any action taken in the manner contemplated by this ‎Section 13.13; provided, however, that neither the Required Creation Cash nor the Required Redemption Cash shall be considered to be part of the Trust Estate.

Section 13.14 Corporate Transparency Act. The Corporate Transparency Act (31 U.S.C. § 5336) and its implementing regulations (collectively, the “CTA”), may require the Trust to file reports with the U.S. Financial Crimes Enforcement Network. It shall be Sponsor’s duty, and not the Trustee’s duty, to prepare such filings, cause the Trust to make such filings, and to cause the Trust to comply with its obligations under the CTA, if any.
