PROMISSORY NOTE DATED September 11, 2026 (“Note”).

PROMISE TO PAY. Heritage Global Inc. ("Borrower") promises to pay to C3bank, National Association ("Lender"), or order, in lawful money of the United States of America, the principal amount of Ten Million & 00/100 Dollars ($10,000,000.00) or so much as may be outstanding, together with interest on the unpaid outstanding principal balance of each advance. Interest shall be calculated from the date of each advance until repayment of each advance.

PAYMENT. Borrower will pay this loan in one payment of all outstanding principal plus all accrued unpaid interest on January 11, 2028. In addition, Borrower will pay regular monthly payments of all accrued unpaid interest due as of each payment date, beginning October 9, 2026, with all subsequent interest payments to be due on the same day of each month after that. Unless otherwise agreed or required by applicable law, payments will be applied first to any accrued unpaid interest; then to principal; then to any late charges; and then to any unpaid collection costs. Borrower will pay Lender at Lender's address shown above or at such other place as Lender may designate in writing.

VARIABLE INTEREST RATE. The interest rate on this Note is subject to change from time to time based on changes in an independent index which is the Prime rate as published in the Wall Street Journal (the "Index"). The Index is not necessarily the lowest rate charged by Lender on its loans. Lender will tell Borrower the current Index rate upon Borrower's request. The interest rate change will not occur more often than each day. Borrower understands that Lender may make loans based on other rates as well. The Index currently is 6.750% per annum. Interest on the unpaid principal balance of this Note will be calculated as described in the "INTEREST CALCULATION METHOD" paragraph using a rate of 1.000 percentage point over the Index (the "Margin"), adjusted if necessary for any minimum and maximum rate limitations described below, resulting in an initial rate of 7.750%. If Lender determines, in its sole discretion, that the Index has become unavailable or unreliable, either temporarily, indefinitely, or permanently, during the term of this Note, Lender may amend this Note by designating a substantially similar substitute index. Lender may also amend and adjust the Margin to accompany the substitute index. The change to the Margin may be a positive or negative value, or zero. In making these amendments, Lender may take into consideration any then-prevailing market convention for selecting a substitute index and margin for the specific Index that is unavailable or unreliable. Such an amendment to the terms of this Note will become effective and bind Borrower 10 business days after Lender gives written notice to Borrower without any action or consent of the Borrower. NOTICE: Under no circumstances will the interest rate on this Note be less than 7.750% per annum or more than the maximum rate allowed by applicable law.

INTEREST CALCULATION METHOD. Interest on this Note is computed on a 365/360 basis; that is, by applying the ratio of the interest rate over a year of 360 days, multiplied by the outstanding principal balance, multiplied by the actual number of days the principal balance is outstanding. All interest payable under this Note is computed using this method. This calculation method results in a higher effective interest rate than the numeric interest rate stated in this Note.

UNUSED LINE FEE. Borrower shall pay to Lender a fee (the "Unused Line Fee") equal to twelve and one-half basis points (0.125%) per annum on the average daily unused portion of the maximum Loan amount. The Unused Line Fee shall accrue commencing on the closing date of this modification (the "Modification Closing Date") and continuing through the maturity date, and shall be calculated and payable in arrears within ten (10) business days following the end of each calendar quarter (each, a "Calculation Period"), with the first payment due for the partial quarter, if any, beginning on the Modification Closing Date. For each Calculation Period, the Unused Line Fee shall be computed by multiplying (i) the average daily unused portion of the maximum Loan amount during such Calculation Period (determined by subtracting, for each day in the Calculation Period, the outstanding principal balance of the Loan on such day from the maximum Loan amount, and then averaging such daily differences over the number of days in the Calculation Period), by (ii) 0.125%, and by (iii) a fraction, the numerator of which is the actual number of days in the Calculation Period and the denominator of which is 360. The Unused Line Fee shall be in addition to, and not in lieu of, interest and all other fees, costs, and expenses payable under the Loan Documents, and shall be fully earned when due and non-refundable when paid.

PRINCIPAL DEPOSITORY REQUIREMENT; RATE ADJUSTMENT. Borrower shall at all times maintain the Principal Depository Requirement as defined in and required by the Business Loan Agreement. In the event Borrower fails to satisfy or maintain the Principal Depository Requirement in accordance with the terms of the Business Loan Agreement, the interest rate then in effect on this Note shall automatically increase by one percentage point (1.00%) per annum (the "Depository Rate Adjustment") above the rate otherwise applicable under this Note, effective immediately following the date on which Lender provides written notice to Borrower of such failure. The Depository Rate Adjustment shall remain in effect for so long as the failure to satisfy the Principal Depository Requirement continues, and shall be removed within five (5) days immediately following the date on which Borrower has, to Lender's reasonable satisfaction, cured such failure and restored full compliance with the Principal Depository Requirement. For the avoidance of doubt, the Depository Rate Adjustment shall be in addition to any other interest rate increase or default rate that may be applicable under this Note or any related Loan Document, and in no event shall the total interest rate on this Note exceed the maximum rate permitted under applicable law.

PREPAYMENT. Borrower may pay without penalty all or a portion of the amount owed earlier than it is due. Early payments will not, unless agreed to by Lender in writing, relieve Borrower of Borrower's obligation to continue to make payments of accrued unpaid interest. Rather, early payments will reduce the principal balance due. Borrower agrees not to send Lender payments marked "paid in full", "without recourse", or similar language. If Borrower sends such a payment, Lender may accept it without losing any of Lender's rights under this Note, and Borrower will remain obligated to pay any further amount owed to Lender. All written communications concerning disputed amounts, including any check or other payment instrument that indicates that the payment constitutes "payment in full" of the amount owed or that is tendered with other conditions or limitations or as full satisfaction of a disputed amount must be mailed or delivered to: C3bank, National Association; Encinitas Office; 850 S Coast Hwy 101; Encinitas, CA 92024.

LATE CHARGE. If a payment is 11 days or more late, Borrower will be charged 6.000% of the regularly scheduled payment or $5.00, whichever is greater.

INTEREST AFTER DEFAULT. Upon maturity of this Note, whether the scheduled maturity date or due to this loan being accelerated by Lender because of a default under this Note, at Lender's option, and if permitted by applicable law, Lender may add any unpaid accrued interest to principal and such sum will bear interest therefrom until paid at the rate provided in this Note (including any increased rate). Upon maturity of this Note, whether the scheduled maturity date or due to this loan being accelerated by Lender because of a default under this Note, the interest rate on this Note shall immediately become 17.000%. However, in no event will the interest rate applied under this paragraph exceed the maximum interest rate permitted under applicable law.

DEFAULT. Each of the following shall constitute an event of default ("Event of Default") under this Note:

Payment Default. Borrower fails to make any payment when due under this Note.

Other Defaults. Borrower fails to comply with or to perform any other term, obligation, covenant or condition contained in this Note or in any of the related documents or to comply with or to perform any term, obligation, covenant or condition contained in any other agreement between Lender and Borrower.

Default in Favor of Third Parties. Borrower or any Grantor defaults under any loan, extension of credit, security agreement, purchase or sales agreement, or any other agreement, in favor of any other creditor or person that may materially affect any of Borrower's property or Borrower's ability to repay this Note or perform Borrower's obligations under this Note or any of the related documents.

False Statements. Any warranty, representation or statement made or furnished to Lender by Borrower or on Borrower's behalf under this Note or the related documents is false or misleading in any material respect, either now or at the time made or furnished or becomes false or misleading at any time thereafter.

Insolvency. The dissolution or termination of Borrower's existence as a going business, the insolvency of Borrower, the appointment of a receiver for any part of Borrower's property, any assignment for the benefit of creditors, any type of creditor workout, or the commencement of any proceeding under any bankruptcy or insolvency laws by or against Borrower.

Creditor or Forfeiture Proceedings. Commencement of foreclosure or forfeiture proceedings, whether by judicial proceeding, self-help, repossession or any other method, by any creditor of Borrower or by any governmental agency against any collateral securing the loan. This includes a garnishment of any of Borrower's accounts, including deposit accounts, with Lender. However, this Event of Default shall not apply if there is a good faith dispute by Borrower as to the validity or reasonableness of the claim which is the basis of the creditor or forfeiture proceeding and if Borrower gives Lender written notice of the creditor or forfeiture proceeding and deposits with Lender monies or a surety bond for the creditor or forfeiture proceeding, in an amount determined by Lender, in its sole discretion, as being an adequate reserve or bond for the dispute.

Events Affecting Guarantor. Any of the preceding events occurs with respect to any guarantor, endorser, surety, or accommodation party of any of the indebtedness or any guarantor, endorser, surety, or accommodation party dies or becomes incompetent, or revokes or disputes the validity of, or liability under, any guaranty of the indebtedness evidenced by this Note.

Change In Ownership. Any change in ownership of twenty-five percent (25%) or more of the common stock of Borrower.

Adverse Change. A material adverse change occurs in Borrower's financial condition, or Lender believes the prospect of payment or performance of this Note is impaired.

Cure Provisions. If any default, other than a default in payment, is curable and if Borrower has not been given a notice of a breach of the same provision of this Note within the preceding twelve (12) months, it may be cured if Borrower, after Lender sends written notice to Borrower demanding cure of such default: (1) cures the default within fifteen (15) days; or (2) if the cure requires more than fifteen (15) days, immediately initiates steps which Lender deems in Lender's sole discretion to be sufficient to cure the default and thereafter continues and completes all reasonable and necessary steps sufficient to produce compliance as soon as reasonably practical.

LENDER'S RIGHTS. Upon default, Lender may declare the entire unpaid principal balance under this Note and all accrued unpaid interest immediately due, and then Borrower will pay that amount.

ATTORNEYS' FEES; EXPENSES. Lender may hire or pay someone else to help collect this Note if Borrower does not pay. Borrower will pay Lender that amount. This includes, subject to any limits under applicable law, Lender's attorneys' fees and Lender's legal expenses, whether or not there is a lawsuit, including attorneys' fees, expenses for bankruptcy proceedings (including efforts to modify or vacate any automatic stay or injunction), and appeals. Borrower also will pay any court costs, in addition to all other sums provided by law.

GOVERNING LAW. This Note will be governed by federal law applicable to Lender and, to the extent not preempted by federal law, the laws of the State of California without regard to its conflicts of law provisions. This Note has been accepted by Lender in the State of California.
