NON-NEGOTIABLE PROMISSORY NOTE

1.    Principal. For value received, as herein provided, Mohawk Group Holdings, Inc., a Delaware corporation (“Borrower”), promises to pay to 9830 Macarthur LLC, a Wyoming limited liability company (“MacArthur”), on behalf of the Lenders (as defined below), the principal amount set forth above (the “Original Principal Amount”), together with interest thereon from the date of this Promissory Note (“Loan”). Interest shall accrue on any portion of the Loan not repaid within 180 days of the date of this Promissory Note at a per annum rate equal to 3.0%, compounded annually, and shall be charged for the actual number of days elapsed, and such interest shall be paid on the Termination Date (as defined below); provided that, if Borrower is late in its payment in respect of any SKU of Specified Inventory, then the per annum rate of 3.0% will increase to 10% solely on the unpaid amount of such SKU and not on the entire outstanding balance of this Promissory Note. Interest shall not accrue on any portion of the Loan repaid within 180 days of the date of this Promissory Note. This Promissory Note is being provided to MacArthur, on behalf of the Lenders, pursuant to that certain Asset Purchase Agreement, dated as of even date herewith, by and among Borrower, MacArthur, Reliance Equities Group, LLC, a Wyoming limited liability company (“Reliance Equities Group”), ZN Direct LLC, a Wyoming limited liability company (“ZN Direct” and together with MacArthur and Reliance Equities Group, collectively, the “Lenders”), and Jelena Puzovic (the “Asset Purchase Agreement”). Capitalized terms used in this Promissory Note without definition shall have the respective meanings set forth in the Asset Purchase Agreement.

2.    Maturity; Payment of the Loan. If any amount remains outstanding hereunder on December 31, 2022 (the “Termination Date”), then such outstanding amount shall be deemed to be no longer outstanding hereunder and shall be added to the Phase 2 Earn Out Amount and have the same repayment rights and obligations as the Phase 2 Earn Out Amount; provided that, prior to the Termination Date, within 30 days of the time at which the remaining amount owed in respect of a particular SKU of Specified Inventory under this Promissory Note is 5% or less than the portion of the Original Principal Amount attributable to such SKU of Specified Inventory at Closing (as noted in Exhibit A attached hereto), then Borrower shall pay to MacArthur the

1

remaining balance of the then outstanding principal value under this Promissory Note attributable to such SKU of Specified Inventory, which payment shall reduce on a dollar-for-dollar basis the then outstanding principal amount under this Promissory note in respect of such SKU of Specified Inventory. Payments shall be made in lawful money of the United States of America. Such payment shall be made at the principal office of MacArthur, or at such other place as MacArthur may from time to time designate in writing to Borrower. Payment shall be credited first to accrued interest due and payable and the remainder applied to principal. If any payment of principal or interest on this Note is due on a day which is not a Business Day, such payment shall be due on the next succeeding Business Day, and such extension of time shall be taken into account in calculating the amount of interest payable under this Promissory Note. “Business Day” means any day other than a Saturday, Sunday or legal holiday in the State of New York.

3.    Repayment of Principal. Each Monthly Inventory Repayment Amount paid by Borrower pursuant to Section 2.8(b) of the Asset Purchase Agreement shall be deemed to be a pro rata repayment of any outstanding principal amount and any accrued interest thereon owing to MacArthur hereunder.

4.    Prepayment. This Promissory Note may be prepaid in full or in part at any time without penalty or premium.

5.    Subordination. MacArthur agrees that it shall promptly take all actions requested by Borrower to effect a subordination of this Promissory Note to any existing or future indebtedness incurred by Borrower with any bank, financial institution or other commercial lender or lessor, whether or not secured, including without limitation, entering into any agreement reasonably requested by such third party, in form reasonably acceptable to MacArthur and its counsel, to implement the foregoing within any reasonable timeframe so requested.

6.    No Waiver By Lender. No waiver of any default shall be implied from any failure of MacArthur to take any action or any delay by MacArthur in taking action with respect to any such default or from any previous waiver of any similar or unrelated default. A waiver of any term of this Promissory Note must be made in writing and shall be limited to the express written terms of such waiver. This Promissory Note shall inure to the benefit of, and be binding upon, Borrower, MacArthur and their respective successors.

7.    Certain Waivers. Borrower and all endorsers jointly and severally waive diligence, grace, demand, presentment for payment, exhibition of this Promissory Note, protest, notice of protest, notice of dishonor, notice of demand, notice of nonpayment, notice of default or delinquency, notice of acceleration, notice of costs or expenses and interest thereon, and notice of any late charges and any and all exemption rights against the indebtedness evidenced by this Promissory Note, and agree to any and all extensions or renewals from time to time without notice and to any partial payments of this Promissory Note made before or after maturity, and that no such extension, renewal or partial payment shall release any one or all of them from the obligation of payment of this Promissory Note or any installment of this Promissory Note, and consent to offsets of any sums owed to any one or all of them by MacArthur at any time.

8.    Loss, Theft, Destruction or Mutilation of Promissory Note. In the event of the loss,

theft or destruction of this Promissory Note, upon Borrower’s receipt of a reasonably satisfactory indemnification agreement executed in favor of Borrower by MacArthur, Borrower shall execute and deliver to MacArthur, a new promissory note in form and content identical to this Promissory Note in lieu of the lost, stolen, destroyed or mutilated Promissory Note.
