EKSO BIONICS HOLDINGS, INC. WAIVER April 23, 2026 Reference is hereby made to that certain Secured Promissory Note and Security Agreement (the “Note”), dated as of September 12, 2025, by and between Ekso Bionics Holdings, Inc., a Nevada corporation (the “Company”), and B. Riley Commercial Capital, LLC, a Delaware limited liability company (the “Lender”). Capitalized terms used herein without definition shall have the same meanings as given to them in the Note. Pursuant to Section 6(a) of the Note, if the closing date of any transaction obligating the Company or any Loan Party to sell or transfer all or substantially all of the assets of the Loan Parties, on a consolidated basis, or which contemplates the sale of a majority of the voting equity interests of the Loan Parties (a “Subject Transaction”), is anticipated to occur earlier than the Maturity Date of the Note, the Lender has the right, but not the obligation, to elect to accelerate the Maturity Date, as to all or any portion of the principal and accrued and unpaid interest, to become concurrent with the closing date of such Subject Transaction. The Company has entered into that certain Contribution and Exchange Agreement, dated February 15, 2026, with APLD Intermediate HoldCo LLC, a Delaware limited liability company, APLD ChronoScale HoldCo LLC, a Delaware limited liability company, and Applied Digital Cloud Corporation, a Nevada corporation, as described in the Company’s Information Statement on Schedule 14C filed with the Securities and Exchange Commission Agreement on April 3, 2026 (the “Contribution and Exchange Agreement” and the transactions contemplated thereby and by the transaction documents executed in connection therewith, collectively, the “Contribution Transactions”). The Contribution Transactions may be deemed to constitute a Subject Transaction under the Note. Pursuant to Section 11(a) of the Note, no provision of the Note may be waived or amended unless the same shall be in writing and signed by the Lender and the Company. The Company and the Lender hereby agree that neither the execution, delivery or performance of the Contribution and Exchange Agreement nor the consummation of any of the Contribution Transactions shall constitute a Subject Transaction for any purpose under the Note, including, without limitation, for purposes of Section 6(a) of the Note. Without limiting the generality of the foregoing, the Lender hereby irrevocably and unconditionally waives, from and after the date hereof, any and all (i) notice, consent, approval or other procedural requirements under the Note that may be triggered by, or applicable to, the Company's execution, delivery and performance of its obligations under the Contribution and Exchange Agreement and/or the consummation of the Contribution Transactions, (ii) rights to elect to accelerate the Maturity Date, or to declare any principal, accrued and unpaid interest, or any other amounts outstanding under the Note to be
2 immediately due and payable, in each case arising from, in connection with, or as a result of the Contribution Transactions, (iii) rights to impose or collect any default rate, premium, penalty or other charge under theNote in connection therewith, and (iv) all other rights, remedies, claims and powers arisingunder theNote, at lawor in equity, ineachcase, solely to theextent arising from, inconnection with, or as a result of theCompany's execution, delivery and performance of its obligations under the Contribution and Exchange Agreement and/or the consummation of the Contribution Transactions, in each case other than any rights to convert theNote in connectionwith the Proposed Financing (as defined below) (the "Subject TransactionWaiver"). In addition, the execution, delivery and performance of the Contribution and Exchange Agreement and the consummation of the Contribution Transactions may give rise to, or result in, (i) a default oranevent of default (howsoeverdefined), or a right todeclare adefault or anevent of default, underor in respect of anyagreement, instrument or otherdocument evidencing, governingor relating to any indebtedness for borrowed money of the Company or any of its subsidiaries (other than the Note) (collectively, "Other Indebtedness"), and/or (ii) the acceleration of, or the right to cause the acceleration of, the maturity of any such Other Indebtedness, in each case, whether arising directly or indirectly from or in connection with the Contribution Transactions (each such occurrence described in clauses (i) and (ii), an "Indebtedness Cross-Default Event"), which Indebtedness Cross-Default Event may constitute an Event of Default under Section 7(b) of the Note. The Lender hereby irrevocably and unconditionally waives, from and after the date hereof, any and all Events of Default under the Note (including, without limitation, any Event of Default arising under Section 7(b) of the Note) that may arise from, in connection with, or as a result of any Indebtedness Cross-Default Event, together with any and all rights, remedies, claims and powers arising therefrom or in connection therewith under the Note or applicable law, including, without limitation, (a) any right to accelerate the Maturity Date or to declare any principal, interest or other amounts outstanding under the Note to be immediately due and payable pursuant to Section 8 of the Note or otherwise, (b) any right to impose or collect the Default Interest Rate or any other default rate, premium, penalty or charge under the Note, (c) any right to exercise any other right or remedy available under theNote, at law or in equity, and (d) any right to deliver any notice of default or notice of acceleration in respect of the foregoing (the“Cross-DefaultWaiver”). For the avoidance of doubt, the Cross-Default waiver shall apply regardless of whether such Indebtedness Cross-Default Event occurs prior to, on, or after the date hereof and regardless of whether the Lender had knowledge or notice of such Indebtedness Cross-Default Event. In addition, pursuant to Section 1(c) of the Note, the Note shall mature, and all of the outstanding LoanAmount, plus any accrued but unpaid interest thereon, and the Exit Fee applicable thereto, shall be due and payable in full in cash on the earlier of (x) the twelve (12)month anniversary of the date of the Note, or (y) the occurrence of aQualified Financing.

The Company and the Lender hereby agree that the Proposed Financing (i) shall not constitute a Qualified Financing for purposes of accelerating the Maturity Date of the Note pursuant to Section 1(c) thereof (the “Qualified Financing Waiver” and together with the Subject Transaction Waiver and theCross-Default, collectively, the“Waiver), but (ii) shall constituteaQualified Financing for all otherpurposes thereunder, including forpurposesof the conversion right in Section10 thereof.
