WORKHORSE GROUP, INC.

Amended and Restated Subordinated Convertible Note

FOR VALUE RECEIVED, Workhorse Group, Inc., a Nevada corporation (the “Company”), hereby promises to pay to Motive GM Holdings II LLC or its permitted registered assigns (“Holder”) the amount set forth above as the Original Principal Amount (the “Principal”) when due, whether upon the Maturity Date, or upon acceleration or otherwise (in each case in accordance with the terms hereof) and to pay interest (“Interest”) on any outstanding Principal at the applicable Interest Rate (as defined below) from the date set forth above as the Issuance Date (the “Issuance Date”) until the same becomes due and payable, whether upon the Maturity Date or upon acceleration, conversion or otherwise (in each case in accordance with the terms hereof). Certain capitalized terms used herein are defined in Section 22.

1. Payments of Principal. Subject to Section 3, on the Maturity Date, the Company shall pay to the Holder an amount in cash representing all outstanding Principal and accrued and unpaid Interest (and for purposes of clarity, the Company shall not be required to make any payments of Interest in cash prior to the Maturity Date, including on any Interest Date (as defined below)). Other than as specifically permitted by this Subordinated Secured Convertible Note (this “Note”), the Company may not prepay any portion of the outstanding Principal or accrued and unpaid Interest.

2. Interest; Interest Rate.

(a) Interest on this Note shall commence accruing on the Issuance Date and shall be computed on the basis of a 360-day year and twelve 30-day months. On the first Business Day of each Fiscal Quarter (each, an “Interest Date”), any accrued and unpaid Interest shall be compounded and become additional Principal outstanding hereunder as of such Interest Date (each, a “Quarterly Compounding”).

(b) Prior to a Quarterly Compounding, interest on this Note shall accrue at the Interest Rate and be payable by way of inclusion of the Interest in the Purchase Amount on any Conversion Date in accordance with Section 3 or any required payment upon any Bankruptcy Event of Default. From and after the occurrence and during the continuance of any Event of Default, the Interest Rate shall automatically be increased to the applicable Default Rate. In the event that such Event of Default is subsequently cured or waived in writing in accordance with the terms of this Note and the other Transaction Documents (and no other Event of Default then exists, including, without limitation, for the Company’s failure to pay such Interest at the Default Rate on the applicable Interest Date), the adjustment referred to in the preceding sentence shall cease to be effective as of the calendar day immediately following the date of such cure or waiver; unless expressly provided therein, any such cure or waiver shall not relieve the Company of its obligation to pay Interest at the Default Rate for the period from the occurrence of such Event of Default through and including the date of such cure or waiver of such Event of Default.

3. Conversion of Note. If there is an Equity Financing in connection with, or after, the Closing (as defined in the Merger Agreement) but on or before the Maturity Date of this Note, on the initial closing date of such Equity Financing (the “Conversion Date”), this Note will automatically convert into the number of shares of Holder Stock equal to the Purchase Amount divided by the Conversion Price. In connection with the automatic conversion of this Note into shares of Holder Stock, the Holder will execute and deliver to the Company all of the transaction documents (the “Equity Documents”) related to the Equity Financing; provided, that such documents are the same documents to be entered into with the purchasers of Standard Stock, with appropriate variations for the Holder Stock if applicable.

The remedies provided in this Note shall be cumulative and in addition to all other remedies available under this Note and any of the other Transaction Documents at law or in equity (including a decree of specific performance and/or other injunctive relief), and nothing herein shall limit the Holder’s right to pursue actual and consequential damages for any failure by the Company to comply with the terms of this Note. No failure on the part of the Holder to exercise, and no delay in exercising, any right, power or remedy hereunder shall operate as a waiver thereof; nor shall any single or partial exercise by the Holder of any right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy. In addition, the exercise of any right or remedy of the Holder at law or equity or under this Note or any of the documents shall not be deemed to be an election of Holder’s rights or remedies under such documents or at law or equity. The Company covenants to the Holder that there shall be no characterization concerning this instrument other than as expressly provided herein. Amounts set forth or provided for herein with respect to payments, conversion and the like (and the computation thereof) shall be the amounts to be received by the Holder and shall not, except as expressly provided herein, be subject to any other obligation of the Company (or the performance thereof). The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Holder and that the remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach, the Holder shall be entitled, in addition to all other available remedies, to specific performance and/or temporary, preliminary and permanent injunctive or other equitable relief from any court of competent jurisdiction in any such case without the necessity of proving actual damages and without posting a bond or other security. The Company shall provide all information and documentation to the Holder that is requested by the Holder to enable the Holder to confirm the Company’s compliance with the terms and conditions of this Note.

13. Payment of Collection, Enforcement and Other Costs. If (a) this Note is placed in the hands of an attorney for collection or enforcement or is collected or enforced through any legal proceeding or the Holder otherwise takes action to collect amounts due under this Note or to enforce the provisions of this Note or (b) there occurs any bankruptcy, reorganization, receivership of the Company or other proceedings affecting Company creditors’ rights and involving a claim under this Note, then the Company shall pay the reasonable, documented (without having the effect of waiving any attorney-client privilege), out-of-pocket costs incurred (the “Collection Costs”) by the Holder for such collection, enforcement or action or in connection with such bankruptcy, reorganization, receivership or other proceeding, including, without limitation, attorneys’ fees and disbursements. The Company expressly acknowledges and agrees that no amounts due under this Note shall be affected, or limited, by the fact that the purchase price paid for this Note was less than the original Principal amount hereof.

14. Construction; Headings. This Note shall be deemed to be jointly drafted by the Company and the initial Holder and shall not be construed against any such Person as the drafter hereof. The headings of this Note are for convenience of reference and shall not form part of, or affect the interpretation of, this Note. Unless the context clearly indicates otherwise, each pronoun herein shall be deemed to include the masculine, feminine, neuter, singular and plural forms thereof. The terms “including,” “includes,” “include” and words of like import shall be construed broadly as if followed by the words “without limitation.” The terms “herein,” “hereunder,” “hereof” and words of like import refer to this entire Note instead of just the provision in which they are found. Unless expressly indicated otherwise, all section references are to sections of this Note. Terms used in this Note and not otherwise defined herein, but defined in the other Transaction Documents, shall have the meanings ascribed to such terms on the Issuance Date in such other Transaction Documents unless otherwise consented to in writing by the Holder.

15. Failure or Indulgence Not Waiver. No failure or delay on the part of the Holder in the exercise of any power, right or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such power, right or privilege preclude other or further exercise thereof or of any other right, power or privilege. No waiver shall be effective unless it is in writing and signed by an authorized representative of the waiving party.

16. Notices; Currency; Payments.

Any notices, consents, waivers or other communications required or permitted to be given under the terms of this Note must be in writing and will be deemed to have been delivered: (i) upon receipt, when delivered personally; (ii) upon receipt, when sent by electronic mail (provided that such sent email is kept on file (whether electronically or otherwise) by the sending party and the sending party does not receive an automatically generated message from the recipient’s email server that such e-mail could not be delivered to such recipient); or (iii) one (1) Business Day after deposit with an overnight courier service with next day delivery specified, in each case, properly addressed to the party to receive the same.

18. Waiver of Notice. To the extent permitted by law, the Company hereby irrevocably waives demand, notice, presentment, protest and all other demands and notices in connection with the delivery, acceptance, performance, default or enforcement of this Note and the other Transaction Documents.

19. Governing Law. This Note shall be construed and enforced in accordance with, and all questions concerning the construction, validity, interpretation and performance of this Note shall be governed by, the internal laws of the State of New York, without giving effect to any provision or rule (whether of the State of New York or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of New York.

Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law.

THE COMPANY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE TO, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH OR ARISING OUT OF THIS NOTE OR ANY TRANSACTION CONTEMPLATED HEREBY.

20. Severability. If any provision of this Note is prohibited by law or otherwise determined to be invalid or unenforceable by a court of competent jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be deemed amended to apply to the broadest extent that it would be valid and enforceable, and the invalidity or unenforceability of such provision shall not affect the validity of the remaining provisions of this Note so long as this Note as so modified continues to express, without material change, the original intentions of the parties as to the subject matter hereof and the prohibited nature, invalidity or unenforceability of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations of the parties or the practical realization of the benefits that would otherwise be conferred upon the parties. The parties will endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s), the effect of which comes as close as possible to that of the prohibited, invalid or unenforceable provision(s).
