This Collar Loan Annex (this “Annex”) is entered into as of 3 August 2026 and forms part of the Loan and Security Agreement (the “Agreement”) between ChainFi, Inc. d/b/a Arch Lending, a Delaware corporation with its principal place of business at 595 Broadway, 4th Floor, New York, NY 10012 (“Lender”), and US Digital Mining and Hosting Co., LLC, a Florida limited liability company whose address is 1200 W Platt Street, Suite 100, Tampa, FL 33606 (“Borrower”). This Annex sets out the terms on which Lender will make available to Borrower a non-recourse, collared, 30-day rolling loan secured by Bitcoin (each such loan, a “Collar Loan”).
1. INCORPORATION, SCOPE AND ORDER OF PRECEDENCE
ChainFi, Inc. d/b/a Arch Lending · Confidential · Annex A - Collar Loan Annex to the Master Loan Agreement 1

Doc ID: dad2598bb2c97cc0141b180f10bf994564f945fb
2. DEFINITIONS
For the purposes of each Collar Loan, the following definitions apply:
“Applicable LTV” means the LTV as at the Reset Time on the Trade Date or, for each subsequent Rolling Period, as at the Reset Time on the Reset Date on which that Rolling Period begins, as specified in the Reset Confirmation for that Rolling Period. The Applicable LTV is the struck figure from which the Floor Price for that Rolling Period is derived. It is recorded once and does not change during the Rolling Period. It is to be distinguished from the LTV, which moves throughout the Rolling Period as the price of the Collateral moves.
“Ceiling Percentage” means the Ceiling Price expressed as a percentage of the Reference Price. It is a derived figure and is not required to be recorded in the Reset Confirmation. The Ceiling Percentage is solved against the Interest Rate for the relevant Rolling Period and is expected to change at each Reset.
“Ceiling Price” means for each Rolling Period, the price per unit of Collateral specified as the Ceiling Price in the Reset Confirmation for that Rolling Period, being an amount equal to the Reference Price multiplied by the Ceiling Percentage. The Ceiling Price, not the Ceiling Percentage, is the figure recorded.
“Collar” means the combination, in respect of each Rolling Period, of the Floor Price and the Ceiling Price, together with any Hedge Transaction entered into by Lender in respect of them.
“Collar Collateral Account” means the segregated wallet or account at the Depository designated as such by Lender and notified to Borrower. All references in the Agreement to the “Depository Account” are, in respect of each Collar Loan, references to the Collar Collateral Account, and the definition of “Depository Account” in Section 3 of the Agreement is amended accordingly so that the account is segregated and not commingled, save in respect of units used under Section 10.2 of this Annex.
“Collar Settlement Value” means in respect of each unit of Collateral and any date of determination, an amount equal to max(Floor Price, min(Reference Price, Ceiling Price)); and, in respect of the Collateral as a whole, that amount multiplied by the number of Pledged Units.
“Coverage” means at any time, the aggregate value of the Pledged Units at the Floor Price then in effect, expressed as a percentage of the Total Loan Amount. Coverage of 100% or more means that the Pledged Units, valued at the Floor Price, are sufficient to discharge the Total Loan Amount in full. Interest accruing during a Rolling Period is not taken into account in Coverage, in the LTV or in the Applicable LTV; it becomes payable on the Reset Date under Section 7.2 of this Annex. The exclusion of interest from Coverage and from the LTV is for measurement purposes only: accrued and unpaid interest forms part of the Secured Obligations, is secured by the Collateral and is recoverable from the Collateral under Sections 6.3 and 8 of this Annex.
“Cure Period” means the period specified as such in the Reset Confirmation for the relevant Rolling Period or, where none is specified, twenty-four (24) hours, in each case running from the Election Deadline on the relevant Reset Date, within which Borrower, having elected by the Election Deadline to roll under Section 5.5(b)(iii) of this Annex, may deliver additional Collateral or make payment so as to eliminate the Floor Shortfall. The Cure Period applies to delivery and payment only, and not to the election itself.
“Election Deadline” means the time on each Reset Date specified as such in the Reset Confirmation, being the latest time by which Borrower may accept the terms recorded in that Reset Confirmation and make its elections under this Annex, in each case by notice to Lender under Section 4.3(c) of this Annex and without any requirement of signature, subject to Lender's discretion to permit a later time under Section 5.7(b) of this Annex.
“Equivalent Units” means units of the same Digital Asset, and of the same number, as the Pledged Units in question. Units of a Digital Asset are fungible for this purpose, and Lender is not obliged to redeliver the identical units originally delivered by Borrower.
“Event of Default” means any event or circumstance specified in Section 12.1 of the Agreement, as amended by Section 9.1 of this Annex, upon the occurrence of which Borrower is stated to be in default.
“Excess Appreciation” means in respect of any Rolling Period, an amount equal to (a) the Reference Price on the relevant Reset Date minus the Ceiling Price for that Rolling Period, multiplied by (b) the number of Pledged Units,

Doc ID: dad2598bb2c97cc0141b180f10bf994564f945fb
where such amount is positive; and zero in all other cases.
“Floor Percentage” means the Floor Price expressed as a percentage of the Reference Price. It is a derived figure and is not required to be recorded in the Reset Confirmation. On the Trade Date, and at each Reset, the Floor Percentage is solved so that Coverage is approximately 100% for the Rolling Period then beginning, taking account of any additional Collateral delivered under Section 5.5(b)(iii) and any adjustment to the Total Loan Amount under Section 5.3 of this Annex, and accordingly approximates the Applicable LTV for that Rolling Period. The Floor Price is a quoted commercial figure and may sit marginally above or below the level at which Coverage is exactly 100%; Section 5.5(a) of this Annex applies to any such difference and any resulting shortfall is borne by Lender.
“Floor Price” means for each Rolling Period, the price per unit of Collateral specified as the Floor Price in the Reset Confirmation for that Rolling Period, being an amount equal to the Reference Price multiplied by the Floor Percentage. The Floor Price, not the Floor Percentage, is the figure recorded.
“Floor Shortfall” means at any time, the amount by which the Total Loan Amount exceeds the aggregate Collateral Market Value of the Pledged Units. A Floor Shortfall will ordinarily arise where the Reference Price is below the Floor Price, and is borne by Lender in accordance with Sections 3.2(d) and 5.5(f) of this Annex.
“Hedge Transaction” means any option, forward, swap or other derivative transaction, or any purchase or sale of Digital Assets, entered into by Lender with a third party for the purpose of hedging, funding or offsetting Lender's exposure under the Collar.
“Interest Rate” means in respect of each Rolling Period, the rate per annum specified as such in the Reset Confirmation for that Rolling Period.
“LTV” means at any time, the Total Loan Amount expressed as a percentage of the aggregate Collateral Market Value of the Pledged Units at that time. The LTV moves continuously with the price of the Collateral throughout each Rolling Period. The definition of “LTV” in Section 3 of the Agreement applies, save that for each Collar Loan
(a) the numerator is the Total Loan Amount and excludes interest accruing during the current Rolling Period, which is dealt with under Section 7.2 of this Annex, and (b) the LTV has no operative consequence during a Rolling Period: it triggers no margin call, no Trigger Event, no cure obligation and no right of Lender to liquidate, at any level, as provided in Sections 5.2 and 6 of this Annex.
“Non-Recourse Carve-Outs” means the matters set out in Section 3.3 of this Annex.
“Pledged Units” means the number of units of Collateral specified as such in the Reset Confirmation, being the units held in the Collar Collateral Account in support of the Collar Loan. Units of Collateral held for Borrower otherwise than in the Collar Collateral Account are not Pledged Units and are not subject to the Collar.
“Reference Price” means the market value of one unit of Collateral, being the last trade price per unit determined by Lender in accordance with Section 7 of the Agreement, as at the Reset Time on the relevant Reset Date (or, in the case of the initial Rolling Period, as at the Reset Time on the Trade Date, subject to re-determination on the Disbursement Date under Section 4.5 of this Annex).
“Repayment Period” means in respect of each Collar Loan, the Rolling Period then in effect. The definition of “Repayment Period” in Section 3 of the Agreement (which is determined by reference to the number of scheduled payments in the Disclosure Statement) does not apply to any Collar Loan.
“Reset” means the re-striking of the Floor Price, the Ceiling Price and the Interest Rate on a Reset Date in accordance with Section 5 of this Annex.
“Reset Confirmation” means the record of the terms of a Rolling Period set out in Schedule 1 to this Annex, completed and issued by Lender for that Rolling Period. Schedule 1 as executed with this Annex is the Reset Confirmation for the initial Rolling Period. For each subsequent Rolling Period, Lender completes and issues a restated Schedule 1, which forms part of this Annex for that Rolling Period on Borrower's acceptance of it under Section 4.3(c) of this Annex. Borrower is not required to execute or countersign any Reset Confirmation, and no term sheet is entered into for any Rolling Period. Terms communicated by Lender at or before a Reset are indicative only until recorded in a Reset Confirmation.

“Reset Date” means the last day of each Rolling Period, being the maturity date of that Rolling Period, and each date on which a Collar Loan is otherwise re-struck by agreement of the parties.
“Reset Time” means the time on each Reset Date specified as such in the Reset Confirmation.
“Rolling Period” means each period of approximately 30 consecutive calendar days beginning on (and including) the Disbursement Date, in the case of the initial Rolling Period, or the day immediately following a Reset Date, in the case of each subsequent Rolling Period; the last day of each such period being the Reset Date for that Rolling Period, subject to extension under Section 9.3 of this Annex, which is not an Event of Default.
“Secured Obligations” means at any time, the aggregate of the Total Loan Amount and all accrued and unpaid interest, late payment fees payable under Section 7.3 of this Annex, Excess Appreciation and Collection Costs then outstanding in respect of the Collar Loan; excluding any Excess Appreciation arising on the date on which the Collar Loan is settled, which is given effect through the cap contained in the definition of Collar Settlement Value and is not additionally recoverable.
“Total Loan Amount” means in respect of each Collar Loan, the aggregate principal amount outstanding from time to time, as increased by any amount added under Section 5.3(c) or Section 5.5(b)(iii) of this Annex and as recorded in the Reset Confirmation then in effect and in Lender's internal records under Section 5.11 of the Agreement. The definition of “Total Loan Amount” in Section 3 of the Agreement (which is determined by reference to the Disclosure Statement) does not apply to any Collar Loan.
“Trade Date” means the date of this Annex.
The collar economics are set in Schedule 1, not here. The Floor Price, Ceiling Price, Applicable LTV, Interest Rate, Reference Price, Reset Time and Election Deadline are defined in this Annex by reference only. Their values are set, and re-set, exclusively in the Reset Confirmation at Schedule 1, which Lender completes and issues for each Rolling Period. Nothing in this Annex fixes any of them. Figures that do not vary by Rolling Period are set in this Annex and are not Reset Confirmation variables. These include the 30/360 interest convention in Section 7.1, the late payment fee in Section 7.3, the judgment threshold in Section 9.1A(d), the arbitration threshold in Section 11.3(b) and the notice and cure periods specified in Sections 4 to 9.

Each Reset Confirmation forms part of this Annex and records the terms of that Rolling Period only. On Borrower's acceptance under paragraph (c) it is binding on both parties, and the terms recorded in the Reset Confirmation delivered under paragraph (b) apply from the commencement of the relevant Rolling Period, except where a notice of non-renewal has been given under Section 4.2 of this Annex or the Collar Loan is maturing under Section 4.4 or Section 5.7(c) of this Annex, in which case Section 8.3 of this Annex governs and the Floor Price and Ceiling Price for the Rolling Period then ending continue to apply until settlement is completed. This Section 4.3 is itself the parties' written agreement to that mechanic for the purposes of Section 16.9 of the Agreement.
(c) where the Reference Price is below the Floor Price, Borrower has not elected to roll and eliminate the Floor Shortfall in accordance with Section 5.5(b)(iii) of this Annex, that elimination being a condition of a roll and not an obligation. Where Borrower has so elected by the Election Deadline, the Collar Loan does not mature at the Election Deadline and instead matures only if the Floor Shortfall is not eliminated by the end of the Cure Period under Section 5.5(b)(iii) of this Annex. The election itself carries no grace period or extension. The Cure Period under Section 5.5(b)(iii) of this Annex extends the time for delivery and payment only, and not the time for electing. Save for that, and save as Lender may permit under Section 5.7(b) of this Annex, the terms quoted under Section 4.3(b) of this Annex lapse at the Election Deadline. A failure to agree is not itself an Event of Default, for the reason given in Section 4.4A, and Borrower has no liability for declining a quote.
(1) Business Day after maturity, or, where maturity results from a failed cure, within the period provided by Section

5. FLOOR AND CEILING MECHANICS; BORROWER OPTIONS AT EACH MATURITY
The table below summarizes the three price zones for convenience. It does not create, limit or vary any right or obligation, and in the event of any inconsistency between it and Sections 5.2 to 5.7 of this Annex, those Sections prevail.
REFERENCE PRICE AT MATURITY | BORROWER CLOSES OUT THE COLLAR LOAN | BORROWER ROLLS THE COLLAR LOAN |
Below the Floor Price | Debt satisfied. Borrower posts nothing and walks away. Lender simply retains the Pledged Units it already holds and the loan ends. Borrower keeps the Loan proceeds. The Pledged Units are worth less than the Total Loan Amount here; the Floor Shortfall is borne by Lender and there is no deficiency claim. Nothing is required of Borrower. Section 5.5(b)(i) of the Annex.
Repayment. Borrower may instead repay the Secured Obligations, and Lender redelivers all Pledged Units. Section 5.5(b)(ii) of the Annex. | Reset, conditional on cure. A roll is available only if Borrower elects by the Election Deadline and eliminates the Floor Shortfall within 24 hours after it, by sending additional Collateral, paying down the Total Loan Amount, or both, so that Coverage returns to approximately 100%. A new structure is then priced and executed at a Floor Price and Ceiling Price struck from the Reference Price. The Collar cost may be capitalized; the shortfall may not. If Borrower does not cure, no roll is available. Section 5.5(b)(iii) of the Annex. |

Between the Floor Price and the Ceiling Price
Standard maturity. Borrower repays the Secured Obligations, including accrued interest, and receives all Pledged Units back. Section 5.5(c) of the Annex.
Refinance. The Collar Loan is extended for a further Rolling Period with a new Floor Price, Ceiling Price and Reset Date, struck from the Reference Price. Section 5.5(c) of the Annex.
Above the Ceiling Price
Capped upside. Borrower repays the Secured Obligations, and Lender retains Pledged Units having a value equal to the Excess Appreciation, or accepts payment of the Excess Appreciation in USD or USDC instead, at Borrower's election. Section 5.5(d) of the Annex.
Refinance. The Collar Loan is rolled into a new structure with a higher Floor Price and Ceiling Price and a new Reset Date. The Excess Appreciation is settled under Sections
5.3 and 5.5(d) of the Annex.
Borrower elects which of paragraphs (a) to (d) applies at each Reset. If Borrower does not elect by the Election Deadline, or is unable to do so, paragraph (a) applies on the automatic maturity of the Collar Loan under Section 5.7(c) of this Annex. Any retention, sale or delivery of Pledged Units under paragraph (a): (i) is effected at Borrower's direction and standing authorization given in this Section; (ii) is not a liquidation of Collateral for the purposes of the Agreement; and (iii) is not subject to the Liquidation Fee under Section 8.6 of the Agreement.

8.3 of this Annex. Borrower may elect paragraph (i) or paragraph (ii) above at any time up to one (1) Business Day after the end of the Cure Period, and if it does not do so the Collar Loan is settled automatically under Section 5.7(c) of this Annex. A failure to complete the cure within the Cure Period is not an Event of Default, and for the purposes of Sections 4.4A and 9.1A(e) of this Annex the period for completing settlement runs from the end of that further one (1) Business Day and not from the Reset Date.
Borrower elects which of paragraphs (i) to (iii) applies at each Reset. A roll is available only under paragraph
(iii). Borrower is under no obligation to deliver additional Collateral or to make any payment, and may elect paragraph (i) in every case; but if Borrower does not eliminate the Floor Shortfall, no roll is available and the

Doc ID: dad2598bb2c97cc0141b180f10bf994564f945fb
Collar Loan is settled under paragraph (i) or paragraph (ii) or, failing an election, automatically under Section 5.7(c) of this Annex. A failure to eliminate the Floor Shortfall is not an Event of Default, is not a margin call for the purposes of Section 6 of this Annex, and entitles Lender to no remedy against Borrower. The only consequences are that no roll is available and that, absent an election, the Collar Loan matures automatically under Section 5.7(c) of this Annex, which is a maturity at term and not a remedy. If Borrower does not elect by the Election Deadline, or is unable to do so, the Collar Loan matures automatically under Section 5.7(c) of this Annex.
5.3 of this Annex. Borrower may elect either (i) to repay the Secured Obligations and close out, in which case Lender retains Pledged Units equal in value to the Excess Appreciation or accepts payment of it in USD or USDC instead, or (ii) to roll, in which case the Collar Loan is rolled into a new structure with a higher Floor Price and Ceiling Price and a new Reset Date, struck from the Reference Price. On a roll, the higher Floor Price raises the level of Borrower's downside protection for the next Rolling Period, and where Coverage then exceeds 100% Borrower may request the release of excess Pledged Units under Section 6.4 of this Annex.
8.3 of this Annex, the resulting shortfall is borne by Lender in accordance with Section 3.2(d) of this Annex, including where Lender has not hedged or a hedge counterparty fails. Any Hedge Transaction is entered into by Lender for its own account, Lender is under no obligation to Borrower to enter into or maintain one, and no Borrower protection under this Annex is conditional upon the existence, performance or sufficiency of any Hedge Transaction. Lender's right to use the Collateral to meet hedging costs is set out in Section 10.2 of this Annex.

10.2 of this Annex, Lender may sell or otherwise dispose of Pledged Units only: (a) to settle Excess Appreciation under Section 5.3 of this Annex; (b) at the written direction of Borrower, to effect repayment or prepayment of a Collar Loan; (c) on settlement of a Collar Loan under Section 8 of this Annex, or on an automatic maturity under Section 5.7(c)(ii) of this Annex; (d) following the occurrence and continuation of an Event of Default surviving under Section 9 of this Annex; or (e) to satisfy interest payable in cash under Section 7.2 of this Annex, or Excess Appreciation payable in cash under Section 5.3(b) of this Annex, which remains unpaid for five (5) Business Days after written notice - and in each case only to the extent, and with the effect, permitted by the non-recourse provisions of Section 3 of this Annex.
7. INTEREST

is calculated on a 30/360 basis, so that interest for a Rolling Period equals the outstanding principal balance multiplied by the Interest Rate multiplied by 30/360, irrespective of the actual number of calendar days in that Rolling Period, and the amount so calculated is specified in the Reset Confirmation. Interest is earned in full for each Rolling Period on the first day of that Rolling Period, and a repayment, prepayment or termination during a Rolling Period does not reduce the interest payable for that Rolling Period. Where Borrower rolls under Section 5.5(b)(iii) of this Annex, the new Rolling Period commences on the day immediately following the Reset Date notwithstanding that the cure is completed during the Cure Period, and interest for the new Rolling Period is earned in full on that day. Where a Rolling Period is extended under Section 9.3 of this Annex, interest continues to accrue for the additional days on a daily simple-interest basis using a 360-day year at the Interest Rate then in effect, and interest continues to accrue on the same daily basis after maturity until settlement is completed in accordance with Section 8.3 of this Annex. A Rolling Period shortened by a mid-period exit under Section 8.2 of this Annex does not reduce the interest payable for that Rolling Period.
8. REPAYMENT, PREPAYMENT AND SETTLEMENT

Doc ID: dad2598bb2c97cc0141b180f10bf994564f945fb
as though that date were a Reset Date.
The Floor Price and Ceiling Price for the Rolling Period ending on that final Reset Date continue to apply until settlement is completed, and no new Rolling Period commences notwithstanding Section 4.3 of this Annex. Where Borrower elects paragraph (b), Borrower is credited with the actual net proceeds of sale rather than the Collar Settlement Value, and accordingly any movement in the price of the Collateral between the final Reset Time and completion of the sale is for Borrower's account, subject always to Borrower retaining the benefit of the Floor Price and Lender retaining any Excess Appreciation. Interest continues to accrue on the outstanding principal balance on a daily simple-interest basis at the Interest Rate from the final Reset Time until settlement is completed, notwithstanding that no new Rolling Period has commenced, and forms part of the Secured Obligations.
9. EVENTS OF DEFAULT
(a) the fifth bullet (Trigger Event) is deleted pursuant to Section 6.1(d) of this Annex; (b) the first bullet applies only to a failure to pay interest payable under Section 7.2 of this Annex, or Excess Appreciation payable in cash under Section 5.3(b), remaining unpaid for five (5) Business Days after written notice, and the qualification in that bullet that “your Collateral value is insufficient to cover it” does not apply, so that such non-payment is an Event of Default whether or not the Pledged Units are sufficient; (c) the bullet relating to death, legal incompetence and incapacity does not apply, Borrower being an entity and not an individual; (d) the bullet relating to a material adverse change in Borrower's financial condition or ability to repay is replaced by the defined triggers in Section 9.1A of this Annex; (e) the bullet relating to false, misleading or materially incomplete statements applies only to statements made at any time (and not only during the Repayment Period as redefined in Section 2 of this Annex) in respect of matters not

disapplied by Section 10.3 of this Annex; and (f) the fourth bullet (failure to comply with any other obligation) does not apply to any obligation disapplied by this Annex.
8.3 of this Annex, by neither repaying the Secured Obligations, nor directing Lender to sell Pledged Units, nor electing that Lender retain them.
For the avoidance of doubt, a decline in the market value of the Collateral, the Pledged Units being worth less than the Total Loan Amount, an LTV in excess of 100% at any time, the existence of a Floor Shortfall and a failure by Borrower to eliminate a Floor Shortfall are not adverse events under this Section and do not constitute an Event of Default.
10. CUSTODY, HEDGING AND ADDITIONAL REPRESENTATIONS

takes credit risk on Lender in respect of that obligation. Nothing in this Section increases Borrower's obligations, creates any recourse against Borrower beyond the Collateral, or affects any election available to Borrower under Section 5.3 or Section 5.5 of this Annex; and where Borrower elects that Lender retain the Pledged Units under Section 5.5(b)(i), that retention extends to Collateral used under this Section.
18 (Authorizations of Borrower), including the consumer credit report, references, spousal and social security number verification authorizations; Section 20 (Additional Disclosures); Section 21 (Notice to Customer); Section 22 (Acknowledgment and Consent); and Exhibit A (Consumer ACH Authorization and Agreement). In addition, because there is no Application in respect of a Collar Loan, Sections 2.1, 16.2 and 17.1 of the Agreement, and the words “including your Application” in Section 16.7, do not apply, and the definitions of “Application”, “Original LTV”, “Disclosure Statement” and “APR” in Section 3 of the Agreement are not applicable to any Collar Loan. Section 17.3 of the Agreement (Survival of Representations) applies at each Reset to the representations as so amended.
