shall cause the Lender (or its custodian, nominee or other designee) to become the registered holder thereof, or cause each issuer of such securities to agree that it will comply with instructions originated by the Lender with respect to such
securities without further consent by Debtors. If any Collateral consists of security entitlements, Debtors shall transfer such security entitlements to the Lender (or its custodian, nominee or other designee) or cause the applicable securities

3



---

Amendment), shall be delivered to the Lender in respect of the Additional Collateral to be pledged pursuant to this
Agreement. Each Debtor hereby authorizes the Lender to attach each Pledge Amendment to this Agreement and agrees that all certificates or instruments listed on any Pledge Amendment delivered to the Lender shall for all purposes hereunder constitute
Collateral.

4.5 If Debtor shall receive, by virtue of Debtor being or having been an owner of any Collateral, any (i) stock
certificate (including, without limitation, any certificate representing a stock dividend or distribution in connection with any increase or reduction of capital, reclassification, merger, consolidation, sale of assets, combination of shares, stock
split, spin-off or split-off), promissory note or other instrument, (ii) option or right, whether as an addition to, substitution for, or in exchange for, any Collateral, or otherwise, (iii) dividends payable in cash (except such dividends
permitted to be retained by Debtor pursuant to Section 5.2 hereof) or in securities or other property or (iv) dividends or other distributions in connection with a partial or total liquidation or dissolution or in connection with a
reduction of capital, capital surplus or paid-in surplus, Debtor shall receive such stock certificate, promissory note, instrument, option, right, payment or distribution in trust for the benefit of the Lender, shall segregate it from Debtors
other property and shall deliver it forthwith to the Lender, in the exact form received, with any necessary endorsement and/or appropriate stock powers duly executed in blank, to be held by the Lender as Collateral and as further collateral security
for the Obligations.

5. Distribution.

5.1 So long as no Event of Default exists, Debtors shall be entitled to exercise all voting power pertaining to any of the Collateral, provided such
exercise is not contrary to the interests of the Lender and does not impair the Collateral.

5.2. At any time an Event of Default exists or
has occurred, all rights of Debtors, upon notice given by the Lender, to exercise the voting power and receive payments, which it would otherwise be entitled to pursuant to Section 5.1, shall cease and all such rights shall thereupon become
vested in the Lender, which shall thereupon have the sole right to exercise such voting power and receive such payments.

5.3 All
dividends, distributions, interest and other payments which are received by Debtors contrary to the provisions of Section 5.2 shall be received in trust for the benefit of the Lender as security and Collateral for payment of the Obligations
shall be segregated from other funds of Debtors, and shall be forthwith paid over to the Lender as Collateral in the exact form received with any necessary endorsement and/or appropriate stock powers duly executed in blank, to be held by the Lender
as Collateral and as further collateral security for the Obligations.

6. Further Action By Debtors; Covenants and
Warranties.

6.1 The Lender at all times shall have a perfected security interest in the Collateral, the Securities, Additional
Collateral (the Perfected Collateral). Each Debtor has and will continue to have full title to the Collateral free from any liens, leases, encumbrances, judgments or other claims. The Lenders security interest in the Collateral
constitutes and will continue to constitute a first, prior and indefeasible security interest in favor of the Lender; provided, however, that Guarantor shall be permitted to obtain a working capital line of credit from a third party commercial
lender secured by its accounts receivable to Blue Bird, Inc. in an amount up to $750,000 (the Permitted Liens) and the Lender agrees to execute such documents as may be necessary or appropriate to subordinate its security interest in
such accounts receivable to such commercial lender. Each Debtor will do all acts and things, and will execute and file all instruments (including, but not limited to, security agreements, financing statements, continuation statements, etc.)
reasonably requested by the Lender to establish, maintain and continue the perfected security interest of the



4



---

Lender in the Perfected Collateral, and will promptly on demand, pay all costs and expenses of filing and recording,
including the costs of any searches reasonably deemed necessary by the Lender from time to time to establish and determine the validity and the continuing priority of the security interest of the Lender, and also pay all other claims and charges
that, in the opinion of the Lender, exercised in good faith, are reasonably likely to materially prejudice, imperil or otherwise affect the Collateral or the Lenders security interests therein.

6.2 Other than in the ordinary course of business, for fair value and in cash, and except for Collateral which is substituted by assets of identical or
greater value (with the consent of the Lender) or which is inconsequential in value, each Debtor will not sell, transfer, assign or pledge those items of Collateral (or allow any such items to be sold, transferred, assigned or pledged), without the
prior written consent of the Lender other than a transfer of the Collateral to a wholly-owned United States formed and located wholly-owned subsidiary or to another Debtor on prior notice to the Lender, and provided the Collateral remains subject to
the security interest herein described. Although Proceeds of Collateral are covered by this Agreement, this shall not be construed to mean that the Lender consents to any sale of the Collateral, except as provided herein. Sales of Collateral in the
ordinary course of business shall be free of the security interest of the Lender and the Lender shall promptly execute such documents (including without limitation releases and termination statements) as may be required by Debtors to evidence or
effectuate the same.

6.3 Each Debtor will, at all reasonable times during regular business hours and upon reasonable notice, allow the
Lender or its representatives free and complete access to the Collateral and all of such Debtors records which in any way relate to the Collateral, for such inspection and examination as the Lender reasonably deems necessary.

6.4 Each Debtor, at its sole cost and expense, will protect and defend this Security Agreement, all of the rights of the Lender hereunder, and the
Collateral against the claims and demands of all other persons.

6.5 Debtors will promptly notify the Lender of any levy, distraint or
other seizure by legal process or otherwise of any part of the Collateral, and of any threatened or filed claims or proceedings that are reasonably likely to affect or impair any of the rights of the Lender under this Security Agreement in any
material respect.

6.6 Each Debtor, at its own expense, will obtain and maintain in force insurance policies covering losses or damage to
those items of Collateral which constitute physical personal property, which insurance shall be of the types customarily insured against by companies in the same or similar business, similarly situated, in such amounts (with such deductible amounts)
as is customary for such companies under the same or similar circumstances, similarly situated. The Lender is hereby irrevocably (until the Obligations are paid in full) appointed each Debtors attorney-in-fact to endorse any check or draft
that may be payable to such Debtor so that the Lender may collect the proceeds payable for any loss under such insurance. The proceeds of such insurance, less any costs and expenses incurred or paid by the Lender in the collection thereof, shall be
applied either toward the cost of the repair or replacement of the items damaged or destroyed, or on account of any sums secured hereby, whether or not then due or payable.

6.7 The Lender may, at its option, and without any obligation to do so, pay, perform and discharge any and all amounts, costs, expenses and liabilities
herein agreed to be paid or performed by Debtor. Upon Debtors failure to do so, all amounts expended by the Lender in so doing shall become part of the Obligations secured hereby, and shall be immediately due and payable by Debtor to
the Lender upon demand and shall bear interest at the lesser of 15% per annum or the highest legal amount from the dates of such expenditures until paid.

6.8 Upon the request of the Lender, Debtors will furnish to the Lender within five (5) business days
thereafter, or to any proposed assignee of this Security Agreement, a written statement in form reasonably satisfactory to the Lender, duly acknowledged, certifying the amount of the principal and interest and any other sum then owing under the
Obligations, whether to its knowledge any claims, offsets or defenses exist against the Obligations or against this Security Agreement, or any of the terms and provisions of any other agreement of Debtors securing the Obligations. In connection with
any assignment by the Lender of this Security Agreement, each Debtor hereby agrees to cause the insurance policies required hereby to be carried by such Debtor, if any, to be endorsed in form satisfactory to the Lender or to such assignee, with loss
payable clauses in favor of such assignee, and to cause such endorsements to be delivered to the Lender within ten (10) calendar days after request therefor by the Lender.

6.9 Each Debtor will, at its own expense, make, execute, endorse, acknowledge, file and/or deliver to the Lender from time to time such vouchers,
invoices, schedules, confirmatory assignments, conveyances, financing statements, transfer endorsements, powers of attorney, certificates, reports and other reasonable assurances or instruments and take further steps relating to the Collateral and
other property or rights covered by the security interest hereby granted, as the Lender may reasonably require to perfect its security interest hereunder.

6.10 Debtors represent and warrant that they are the true and lawful exclusive owners of the Collateral, free and clear of any liens and encumbrances other than Permitted Liens.

6.11 Each Debtor hereby agrees not to divest itself of any right under the Collateral except as permitted herein absent prior written approval of the
Lender, except to a subsidiary organized and located in the United States on prior notice to the Lender provided the Collateral remains subject to the security interest herein described.

6.12 Each Debtor shall cause each Subsidiary of such Debtor in existence on the date hereof and each Subsidiary not in existence on the date hereof to
execute and deliver to the Lender promptly and in any event within 10 days after the formation, acquisition or change in status thereof (A) a guarantee guaranteeing the Obligations and (B) if requested by the Lender, a security and pledge
agreement substantially in the form of this Agreement together with (x) certificates evidencing all of the capital stock of each Subsidiary of and any entity owned by such Subsidiary, (y) undated stock powers executed in blank with
signatures guaranteed, and (z) such opinion of counsel and such approving certificate of such Subsidiary as the Lender may reasonably request in respect of complying with any legend on any such certificate or any other matter relating to such
shares and (C) such other agreements, instruments, approvals, legal opinions or other documents reasonably requested by the Lender in order to create, perfect, establish the first priority of or otherwise protect any lien purported to be
covered by any such pledge and security agreement or otherwise to effect the intent that all property and assets of such Subsidiary shall become Collateral for the Obligations. For purposes of this Agreement, Subsidiary means,
with respect to any entity at any date, any corporation, limited or general partnership, limited liability company, trust, estate, association, joint venture or other business entity) of which more than 50% of (A) the outstanding capital
stock having (in the absence of contingencies) ordinary voting power to elect a majority of the board of directors or other managing body of such entity, (B) in the case of a partnership or limited liability company, the interest in the capital
or profits of such partnership or limited liability company or (C) in the case of a trust, estate, association, joint venture or other entity, the beneficial interest in such trust, estate, association or other entity business is, at the time
of determination, owned or controlled directly or indirectly through one or more intermediaries, by such entity. Annex I annexed hereto contains a list of all Subsidiaries of the Debtors as of the date of this Agreement.

7. Power of Attorney.

At any time an Event of Default exists or has occurred, each Debtor hereby irrevocably constitutes and appoints the Lender as the true and lawful attorney
of such Debtor, with full power of substitution, in the place and stead of such Debtor and in the name of such Debtor or otherwise, at any time or times, in the discretion of the Lender, to take any action and to execute any instrument or document
which the Lender may deem necessary or advisable to accomplish the purposes of this Agreement. This power of attorney is coupled with an interest and is irrevocable until the Obligations are satisfied.

8. Performance By The Lender.

If a Debtor fails to perform any material covenant, agreement, duty or obligation of such Debtor under this Agreement, the Lender may, after any applicable cure period, at any time or times in its discretion, take
action to effect performance of such obligation. All reasonable expenses of the Lender incurred in connection with the foregoing authorization shall be payable by Debtors as provided in Paragraph 12.1 hereof. No discretionary right, remedy or power
granted to the Lender under any part of this Agreement shall be deemed to impose any obligation whatsoever on the Lender with respect thereto, such rights, remedies and powers being solely for the protection of the Lender.

9. Event of Default.

An event of default (Event of Default) shall be deemed to have occurred hereunder upon the occurrence of any event of default as defined and described in this Agreement, in the Notes, the Subscription Agreement, and any other
agreement to which Debtor and a Lender are parties. Upon and after any Event of Default, after the applicable cure period, if any, any or all of the Obligations shall become immediately due and payable at the option of the Lender, and the Lender may
dispose of Collateral as provided below. A default by Debtor of any of its material obligations pursuant to this Agreement and any of the Transaction Documents (as defined in the Subscription Agreement) shall be an Event of Default hereunder and an
Event of Default as defined in the Notes, and Subscription Agreement.

10. Disposition of Collateral.

Upon and after any Event of Default which is then continuing,

10.1 The Lender may exercise its rights with respect to each and every component of the Collateral, without regard to the existence of any other security
or source of payment for the Obligations. In addition to other rights and remedies provided for herein or otherwise available to it, the Lender shall have all of the rights and remedies of a lender on default under the Uniform Commercial Code then
in effect in the State of New York.

10.2 If any notice to Debtors of the sale or other disposition of Collateral is required by then
applicable law, ten business (10) days prior written notice (which Debtors agree is reasonable notice within the meaning of Section 9.612(a) of the Uniform Commercial Code) shall be given to Debtors of the time and place of any sale of
Collateral which Debtors hereby agree may be by private sale. The rights granted in this Section are in addition to any and all rights available to Lender under the Uniform Commercial Code.

10.3 The Lender is authorized, at any such sale, if the Lender deems it advisable to do so, in order to comply with any applicable securities laws, to
restrict the prospective bidders or purchasers to persons who will represent and agree, among other things, that they are purchasing the Collateral for their own account for investment, and not with a view to the distribution or resale thereof, or
otherwise to restrict such sale in such other manner as the Lender deems advisable to ensure such compliance. Sales made subject to such restrictions shall be deemed to have been made in a commercially reasonable manner.

---

10.4 All proceeds received by the Lender in respect of any sale, collection or other enforcement or
disposition of Collateral, shall be applied (after deduction of any amounts payable to the Lender pursuant to Paragraph 12.1 hereof) against the Obligations. Upon payment in full of all Obligations, Debtors shall be entitled to the return of all
Collateral, including cash, which has not been used or applied toward the payment of Obligations or used or applied to any and all costs or expenses of the Lender incurred in connection with the liquidation of the Collateral (unless another person
is legally entitled thereto). Any assignment of Collateral by the Lende to Debtors shall be without representation or warranty of any nature whatsoever and wholly without recourse. To the extent allowed by law, Lender may purchase the Collateral and
pay for such purchase by offsetting the purchase price with sums owed to Lender by Debtors arising under the Obligations or any other source.

11.
Waiver of Automatic Stay. Debtor acknowledges and agrees that should a proceeding under any bankruptcy or insolvency law be commenced by or against Debtor, or if any of the Collateral should become the subject of any bankruptcy or insolvency
proceeding, then the Lender should be entitled to, among other relief to which the Lender may be entitled under the Note, Subscription Agreement and any other agreement to which the Debtor and Lender are parties, (collectively Loan
Documents) and/or applicable law, an order from the court granting immediate relief from the automatic stay pursuant to 11 U.S.C. Section 362 to permit the Lender to exercise all of its rights and remedies pursuant to the Loan Documents
and/or applicable law. DEBTOR EXPRESSLY WAIVES THE BENEFIT OF THE AUTOMATIC STAY IMPOSED BY 11 U.S.C. SECTION 362. FURTHERMORE, DEBTOR EXPRESSLY ACKNOWLEDGES AND AGREES THAT NEITHER 11 U.S.C. SECTION 362 NOR ANY OTHER SECTION OF THE BANKRUPTCY CODE
OR OTHER STATUTE OR RULE (INCLUDING, WITHOUT LIMITATION, 11 U.S.C. SECTION 105) SHALL STAY, INTERDICT, CONDITION, REDUCE OR INHIBIT IN ANY WAY THE ABILITY OF THE LENDER TO ENFORCE ANY OF ITS RIGHTS AND REMEDIES UNDER THE LOAN DOCUMENTS AND/OR
APPLICABLE LAW. Debtor hereby consents to any motion for relief from stay which may be filed by the Lender in any bankruptcy or insolvency proceeding initiated by or against Debtor, and further agrees not to file any opposition to any motion for
relief from stay filed by the Lender. Debtor represents, acknowledges and agrees that this provision is a specific and material aspect of this Agreement, and that the Lender would not agree to the terms of this Agreement if this waiver were not a
part of this Agreement. Debtor further represents, acknowledges and agrees that this waiver is knowingly, intelligently and voluntarily made, that neither the Lender nor any person acting on behalf of the Lender has made any representations to
induce this waiver, that Debtor has been represented (or has had the opportunity to be represented) in the signing of this Agreement and in the making of this waiver by independent legal counsel selected by Debtor and that Debtor has had the
opportunity to discuss this waiver with counsel.

12. Miscellaneous.

12.1 Expenses. Debtors shall pay to the Lender, on demand, the amount of any and all reasonable expenses, including, without limitation,
attorneys fees, legal expenses and brokers fees, which the Lender may incur in connection with (a) sale, collection or other enforcement or disposition of Collateral; (b) exercise or enforcement of any the rights, remedies or
powers of the Lender hereunder or with respect to any or all of the Obligations upon breach or threatened breach; or (c) failure by Debtors to perform and observe any agreements of Debtors contained herein which are performed by the Lender.

12.2 Waivers, Amendment and Remedies. No course of dealing by the Lender and no failure by the Lender to exercise, or delay by the
Lender in exercising, any right, remedy or power hereunder shall operate as a waiver thereof, and no single or partial exercise thereof shall preclude any other or further



8



---

exercise thereof or the exercise of any other right, remedy or power of the Lender. No amendment, modification or waiver
of any provision of this Agreement and no consent to any departure by Debtors therefrom, shall, in any event, be effective unless contained in a writing signed by the Lender, and then such waiver or consent shall be effective only in the specific
instance and for the specific purpose for which given. The rights, remedies and powers of the Lender, not only hereunder, but also under any instruments and agreements evidencing or securing the Obligations and under applicable law are cumulative,
and may be exercised by the Lender from time to time in such order as the Lender may elect.
